ABOUT OUR BUSINESS THE FOLLOWING IS A SHORT SUMMARY OF OUR BUSINESS. YOU SHOULD CAREFULLY READ THE "RISK FACTORS" SECTION OF THIS PROSPECTUS AND OUR AMENDED ANNUAL REPORT ON FORM 10-K/A FOR THE YEAR ENDED DECEMBER 31, 1999 FOR MORE INFORMATION ON OUR BUSINESS AND THE RISKS INVOLVED IN INVESTING IN THE NOTES AND THE COMMON STOCK ISSUABLE UPON CONVERSION OF THE NOTES. IN ADDITION TO THE HISTORICAL INFORMATION CONTAINED IN THIS PROSPECTUS, THIS PROSPECTUS CONTAINS FORWARD-LOOKING STATEMENTS WITHIN THE MEANING OF SECTION 27A OF THE SECURITIES ACT AND SECTION 21E OF THE EXCHANGE ACT THAT INVOLVE RISKS AND UNCERTAINTIES. OUR ACTUAL RESULTS COULD DIFFER MATERIALLY FROM OUR EXPECTATIONS. FACTORS THAT COULD CAUSE OR CONTRIBUTE TO SUCH DIFFERENCES ARE DISCUSSED IN "RISK FACTORS" BEGINNING AT PAGE 3 OF THIS PROSPECTUS AND IN "MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS" AND "BUSINESS" IN OUR AMENDED ANNUAL REPORT. We are creating a drug delivery system to easily and painlessly deliver a wide range of drugs, including peptides, proteins, and other molecules, by inhalation to the deep lung for treatment of systemic and respiratory diseases. We are using this system principally to enable non-invasive delivery of macromolecule drugs currently administered by injection. Our most advanced program, which is sponsored by Pfizer Inc., is inhaleable insulin. Pfizer commenced dosing for its Phase III human clinical trials in June 1999. In addition to our insulin program with Pfizer, we have development collaborations with Biogen, Inc., Aventis Behring LLC (a division of Aventis S.A.), and Eli Lilly and Co. We also have early stage feasibility and research collaborations with several other companies and have tested eight drugs in human clinical trials. Currently there are approximately 35 macromolecule drugs marketed in the United States and about 120 other such drugs in human clinical trials. Sales of the top 15 genetically engineered protein drugs (a subset of macromolecule drugs) were estimated at $15.6 billion worldwide in 1999. Most of these drugs are currently delivered by injection. Injections are undesirable for numerous reasons including patient discomfort, inconvenience and risk of infection. Poor patient acceptance of, and compliance with, injectable therapies can lead to increased incidence of medical complications and higher disease management costs. Alternatives to injection such as oral, transdermal and nasal delivery have to date been shown generally to be commercially unattractive due to low natural bioavailability-the amount of drug absorbed from the delivery site into the bloodstream relative to injection. As an alternative to the invasiveness of injection, we believe a deep lung inhalation delivery system could expand the market for protein drug therapies by increasing patient acceptance and improving compliance and may enable new therapeutic uses of certain macromolecule drugs. We are creating a proprietary technology platform integrating customized formulation, dry powder processing and packaging with a proprietary inhalation devices to enable efficient, reproducible delivery of macromolecule drugs for systemic and local lung indications. For specific drug products, we formulate and process bulk drugs supplied by collaborative partners into dry powders which are packaged into individual dosing units referred to as blisters. The blisters are designed to be loaded into our devices, which patients then activate to inhale the aerosolized drugs. We have developed an inhalation device that is being used several times per day for several months in outpatient trials for insulin. In addition, we have demonstrated room temperature stability of a year or more for a number of macromolecule drugs, and have scaled-up our powder processing and packaging for late stage clinical trials and small scale production for certain drugs. Our most advanced product is inhaleable insulin for Type 1 and Type 2 diabetes, which is being developed through a collaborative program with Pfizer. Worldwide insulin and insulin delivery systems sales were estimated to be $3.2 billion in 1998. Data published by Pfizer and clinical investigators from a 190 person Phase IIb human clinical trial using our drug delivery system showed that inhaleable insulin provided statistically equivalent control of diabetes when compared with injectable mealtime insulin for diabetics on insulin, and improved control of diabetes when compared with injectable mealtime insulin for diabetics on insulin, and improved control of diabetes for patients poorly 3 controlled on oral therapies. The Phase III trials involve approximately 120 clinical sites. In November 1998, Pfizer announced that it entered into a co-development and co-promotion arrangement with Aventis for inhaleable insulin. Pfizer and Aventis have reported plans to invest over 300 million DM (approximately US$134 million) for the construction of a jointly-owned manufacturing facility in Germany for the supply of insulin for pulmonary delivery. This state-of-the-art insulin plant is projected to be the largest of its kind in the world. We will receive royalties on inhaleable insulin products marketed by Pfizer and Aventis as well as revenues for supplying devices and powders. In a typical collaboration, our partner will provide the drug, fund clinical development and market the resulting commercial product. We will supply the delivery system and receive revenues from powder manufacturing, device supply and royalties from sales of any commercial products. Prior to commercialization, we receive revenues from our partners for research and development funding and progress payments upon achievement of certain developmental milestones. In addition to Pfizer's sponsorship of our inhaleable insulin program, we have active pulmonary delivery development programs with Biogen for AVONEX-Registered Trademark-, an interferon beta drug used in the treatment of Multiple Sclerosis; Aventis Behring for an alpha-1 antitrypsin proteinase inhibitor being used for the treatment of genetic emphysema; and Lilly for Forteo-TM-, a parathyroid hormone, or PTH 1-34, being developed for the treatment of osteoporosis. These and other ongoing projects in various stages of research, formulation and clinical development have been selected as focus programs by us because we believe our approach may have significant advantages over current therapies. We anticipate that any product that may be developed would be commercialized with a collaborative partner and believe our partnering strategy will enable us to reduce the investment required to develop a large and diversified potential product portfolio.

ALL FORWARD-LOOKING STATEMENTS AND REASONS WHY RESULTS MAY DIFFER INCLUDED IN THIS PROSPECTUS ARE MADE AS OF THE DATE HEREOF AND WE ASSUME NO OBLIGATION TO UPDATE ANY SUCH FORWARD-LOOKING STATEMENT OR REASON WHY ACTUAL RESULTS MIGHT DIFFER. WE DO NOT KNOW IF OUR DEEP LUNG DRUG DELIVERY SYSTEM IS COMMERCIALLY FEASIBLE. We are in an early stage of development. There is a risk that our deep lung drug delivery technology will not be commercially feasible. Even if our deep lung delivery technology is commercially feasible, it may not be commercially accepted across a range of large and small molecule drugs. We have tested eight deep lung delivery formulations in humans, but many of our potential formulations have not been tested in humans. Many of the underlying drug compounds contained in our deep lung formulations have been tested in humans by other companies using alternative delivery routes. Our potential products require extensive research, development and preclinical (animal) and clinical (human) testing. Our potential products also may involve lengthy regulatory review before they can be sold. We do not know if, and cannot assure you that any of our potential products will prove to be safe and effective or meet regulatory standards. There is a risk that any of our potential products will not be able to be produced in commercial quantities at acceptable cost or marketed successfully. Our failure to achieve commercial feasibility, demonstrate safety, achieve clinical efficacy, obtain regulatory approval or, together with partners, successfully market products will negatively impact our revenues and results of operations. WE DO NOT KNOW IF OUR DEEP LUNG DRUG DELIVERY SYSTEM IS EFFICIENT. We may not be able to achieve the total system efficiency needed to be competitive with alternative routes of delivery. Total system efficiency is determined by the amount of drug loss during manufacture, in the delivery device, in reaching the site of absorption, and during absorption from that site into the bloodstream. Deep lung bioavailability is the percentage of a drug that is absorbed into the bloodstream when that drug is delivered directly to the lungs as compared to injection. Bioavailability is the initial screen for whether deep lung delivery of any systemic drug is commercially feasible. We would not consider a drug to be a good candidate for development and commercialization if its drug loss is excessive at any one stage or cumulatively in the manufacturing and delivery process or if its deep lung bioavailability is too low. 5 WE DO NOT KNOW IF OUR DEEP LUNG DRUG FORMULATIONS ARE STABLE. We may not be able to identify and produce powdered versions of drugs that retain the physical and chemical properties needed to work with our delivery device. Formulation stability is the physical and chemical stability of the drug over time and under various storage, shipping and usage conditions. Formulation stability will vary with each deep lung formulation and the type and amount of ingredients that are used in the formulation. Problems with powdered drug stability would negatively impact our ability to develop and market our potential products or obtain regulatory approval. WE DO NOT KNOW IF OUR DEEP LUNG DRUG DELIVERY SYSTEM IS SAFE. We may not be able to prove potential products to be safe. Our products require lengthy laboratory, animal and human testing. Most of our products are in preclinical testing or the early stage of human testing. If we find that any product is not safe, we will not be able to commercialize the product. The safety of our deep lung formulations will vary with each drug and the ingredients used in its formulation. WE DO NOT KNOW IF OUR DEEP LUNG DRUG DELIVERY SYSTEM PROVIDES CONSISTENT DOSES OF MEDICINE. We may not be able to provide reproducible dosages of stable formulations sufficient to achieve clinical or commercial success. Reproducible dosing is the ability to deliver a consistent and predictable amount of drug into the bloodstream over time both for a single patient and across patient groups. Reproducible dosing requires the development of: - an inhalation device that consistently delivers predictable amounts of dry powder formulations to the deep lung; - accurate unit dose packaging of dry powder formulations; and - moisture resistant packaging. We may not be able to develop reproducible dosing of any potential product. The failure to do so means that we would not consider it a good candidate for development and commercialization. WE DEPEND ON PARTNERS FOR REGULATORY APPROVALS AND COMMERCIALIZATION OF OUR PRODUCTS. Because we are in the business of developing technology for delivering drugs to the lungs and licensing this technology to companies that make and sell drugs, we do not have the people and other resources to do the following things: - make bulk drugs to be used as medicines; - design and carry out large scale clinical studies; - prepare and file documents necessary to obtain government approval to sell a given drug product; and - market and sell our products when and if they are approved. When we sign a collaborative development agreement or license agreement to develop a product with a drug company, the drug company agrees to do some or all of the things described above. If our partner fails to do any of these things, we cannot complete the development of the product. WE MAY NOT OBTAIN REGULATORY APPROVAL FOR OUR PRODUCTS ON A TIMELY BASIS, OR AT ALL. There is a risk that we will not obtain regulatory approval for our products on a timely basis, or at all. Our product must undergo rigorous laboratory animal and human testing and an extensive review process mandated by the United States Food and Drug Administration ("FDA") and equivalent foreign 6 authorities. This process generally takes a number of years and requires the expenditure of substantial resources although the time required for completing such testing and obtaining such approvals is uncertain. We have not submitted any of our products to the FDA for marketing approval. We have no experience obtaining such regulatory approval. In addition, we may encounter delays or rejections based upon changes in FDA policy, including policy relating to good manufacturing practice compliance, or "cGMP", during the period of product development. We may encounter similar delays in other countries. Even if regulatory approval of a product is granted, the approval may limit the indicated uses for which we may market our product. In addition, our marketed product, our manufacturing facilities and Inhale, as the manufacturer, will be subject to continual review and periodic inspections. Later discovery from such review and inspection of previously unknown problems may result in restrictions on our product or on us, including withdrawal of our product from the market. The failure to obtain timely regulatory approval of our products, any product marketing limitations or a product withdrawal would negatively impact our revenues and results of operations. WE DO NOT KNOW IF OUR TECHNOLOGIES CAN BE INTEGRATED SUCCESSFULLY TO BRING PRODUCTS TO MARKET. We may not be able to integrate all of the relevant technologies to provide a deep lung drug delivery system. Our integrated approach to systems development relies upon several different but related technologies: - dry powder formulations; - dry powder processing technology; - dry powder packaging technology; and - a deep lung delivery device. At the same time, we must: - establish collaborations with partners; - perform laboratory and clinical testing of potential products; and - scale-up our manufacturing processes. We must accomplish all of these steps without delaying any aspect of technology development. Any delay in one component of our products or business development activities could delay our ability to develop, obtain approval of or market therapeutic products using our deep lung delivery technology. WE MAY NOT BE ABLE TO MANUFACTURE OUR PRODUCTS IN COMMERCIAL QUANTITIES. POWDER PROCESSING. We have no experience manufacturing products for commercial purposes. We have only performed powder processing on the small scale needed for testing formulations and for early stage and larger clinical trials. We may encounter manufacturing and control problems as we attempt to scale-up powder processing facilities. We may not be able to achieve such scale-up in a timely manner or at a commercially reasonable cost, if at all. Our failure to solve any of these problems could delay or prevent late stage clinical testing and commercialization of our products and could negatively impact our revenues and results of operations. To date, we have relied primarily on one particular method of powder processing. There is a risk that this technology will not work with all drugs or that the cost of drug production will preclude the commercial viability of certain drugs. Additionally, there is a risk that any alternative powder processing methods we may pursue will not be commercially practical for aerosol drugs or that we will not have, or be able to acquire the rights to use, such alternative methods. 7 POWDER PACKAGING. Our fine particle powders and small quantity packaging require special handling. We have designed and qualified automated filling equipment for small and moderate quantity packaging of fine powders. We face significant technical challenges in scaling-up an automated filling system that can handle the small dose and particle sizes of our powders in commercial quantities. There is a risk that we will not be able to scale-up our automated filling equipment in a timely manner or at commercially reasonable costs. Any failure or delay in such scale-up would delay product development or bar commercialization of our products and would negatively impact our revenues and results of operations. INHALATION DEVICES. We face many technical challenges in further developing our inhalation devices to work with a broad range of drugs, to produce such devices in sufficient quantities and to adapt the devices to different powder formulations. There is a risk that we will not successfully achieve any of these things. Our failure to overcome any of these things would negatively impact our revenues and results of operations. For late stage clinical trials and initial commercial production, we intend to use one or more contract manufacturers to produce our drug delivery devices. There is a risk that we will not be able to enter into or maintain arrangements with potential contract manufacturers or effectively scale-up production of our drug delivery devices through contract manufacturers that we identify. Our failure to do so would negatively impact our revenues and results of operations. WE DEPEND ON SOLE OR EXCLUSIVE SUPPLIERS FOR OUR INHALATION DEVICES AND BULK DRUGS. We plan to subcontract the manufacture of our pulmonary delivery devices before commercial production of our first products. We have identified contract manufacturers that we believe have the technical capabilities and production capacity to manufacture our devices and which can meet the requirements of good manufacturing practices. We cannot be assured that we will be able to obtain and maintain satisfactory contract manufacturing on commercially acceptable terms, if at all. Our dependence on third parties for the manufacture of our inhalation device may negatively impact our cost of goods and our ability to develop and commercialize products on a timely and competitive basis. We obtain the bulk drugs we use to formulate and manufacture the dry powders for our deep lung delivery systems from sole or exclusive sources of supply. For example, with respect to our source of bulk insulin, we have entered into a collaborative agreement with Pfizer which has, in turn, entered into an agreement with Aventis to manufacture biosynthetic recombinant insulin. Under the terms of their agreement, Pfizer and Aventis agreed to construct a jointly owned manufacturing plant in Frankfurt, Germany. Until its completion, Pfizer will provide us with insulin from Aventis's existing plant. If our sole or exclusive source suppliers fail to provide bulk drugs in sufficient quantities when required, our revenues and results of operations will be negatively impacted. WE DO NOT KNOW IF THE MARKET WILL ACCEPT OUR DEEP LUNG DRUG DELIVERY SYSTEM. The commercial success of our potential products depends upon market acceptance by health care providers, third-party payors like health insurance companies and Medicare, and patients. Our products under development use a new method of drug delivery and there is a risk that our potential products will not be accepted by the market. Market acceptance will depend on many factors, including: - the safety and efficacy results of our clinical trials; - favorable regulatory approval and product labeling; - the frequency of product use; - the availability of third-party reimbursement; - the availability of alternative technologies; and 8 - the price of our products relative to alternative technologies. There is a risk that health care providers, patients or third-party payors will not accept our deep lung drug delivery system. If the market does not accept our potential products, our revenues and results of operations would be significantly and negatively impacted. IF OUR PRODUCTS ARE NOT COST EFFECTIVE, GOVERNMENT AND PRIVATE INSURANCE PLANS WILL NOT PAY FOR OUR PRODUCTS. In both domestic and foreign markets, sales of our products under development will depend in part upon the availability of reimbursement from third-party payors, such as government health administration authorities, managed care providers, private health insurers and other organizations. In addition, such third-party payors are increasingly challenging the price and cost effectiveness of medical products and services. Significant uncertainty exists as to the reimbursement status of newly approved health care products. Legislation and regulations affecting the pricing of pharmaceuticals may change before our proposed products are approved for marketing. Adoption of such legislation and regulations could further limit reimbursement for medical products. A government or third-party payor decision to not provide adequate coverage and reimbursements for our products would limit market acceptance of such products. WE EXPECT TO CONTINUE TO LOSE MONEY FOR THE NEXT SEVERAL YEARS. We have never been profitable and, through September 30, 2000, have incurred a cumulative deficit of approximately $152.3 million. We expect to continue to incur substantial and increasing losses over at least the next several years as we expand our research and development efforts, testing activities and manufacturing operations, and as we further expand our late stage clinical and early commercial production facility. All of our potential products are in research or in the early stages of development except for our insulin collaboration. We have generated no revenues from approved product sales. Our revenues to date have consisted primarily of payments under short-term research and feasibility agreements and development contracts. To achieve and sustain profitable operations, we must, alone or with others, successfully develop, obtain regulatory approval for, manufacture, introduce, market and sell products using our deep lung drug delivery system. There is a risk that we will not generate sufficient product or contract research revenue to become profitable or to sustain profitability. WE MAY NEED TO RAISE ADDITIONAL CAPITAL THAT MAY NOT BE AVAILABLE. We anticipate that our existing capital resources will enable us to maintain currently planned operations through at least the next 34 months. However, this expectation is based on our current operating plan, which is expected to change as a result of many factors, and we may need additional funding sooner than anticipated. In addition, we may choose to raise additional capital due to market conditions or strategic considerations, even if we believe we have sufficient funds for our current or future operating plans. To the extent that additional capital is raised through the sale of equity or convertible debt securities, the issuance of such securities could result in dilution to our stockholders. We have no credit facility or other committed sources of capital. To the extent operating and capital resources are insufficient to meet future requirements, we will have to raise additional funds to continue the development and commercialization of our technologies. Such funds may not be available on favorable terms, or at all. In particular, our substantial leverage may limit our ability to obtain additional financing. If adequate funds are not available on reasonable terms, we may be required to curtail operations significantly or to obtain funds by entering into financing, supply or collaboration agreements on unattractive terms. Our inability to raise capital could negatively impact our business. 9 IF WE FAIL TO MANAGE OUR GROWTH EFFECTIVELY, OUR BUSINESS MAY SUFFER. Our ability to commercialize our products, achieve our expansion objectives, manage our growth effectively and satisfy our commitments under our collaboration agreements depends on a variety of factors. Key factors include our ability to develop products internally, enter into strategic partnerships with collaborators, attract and retain skilled employees and effectively expand our internal organization to accommodate anticipated growth including integration of any potential businesses that we may acquire. If we are unable to manage growth effectively, there could be a material adverse effect on our business, financial condition and results of operations. OUR PATENTS MAY NOT PROTECT OUR PRODUCTS AND OUR PRODUCTS MAY INFRINGE ON THIRD-PARTY PATENT RIGHTS. We have filed patent applications covering certain aspects of our device, powder processing technology, and powder formulations and deep lung route of delivery for certain molecules, and we plan to file additional patent applications. We currently have 100 issued U.S. and foreign patents that cover certain aspects of our technology and we have a number of patent applications pending. There is a risk that any of the patents applied for will not issue, or that any patents that issue or have issued will not be valid and enforceable. Enforcing our patent rights would be time consuming and costly. Our access or our partners' access to the drugs to be formulated will affect our ability to develop and commercialize our technology. Many drugs, including powder formulations of certain drugs that are presently under development by us, are subject to issued and pending U.S. and foreign patents that may be owned by our competitors. We know that there are issued patents and pending patent applications relating to the deep lung delivery of large molecule drugs, including several for which we are developing deep lung delivery formulations. This situation is highly complex, and the ability of any one company, including Inhale, to commercialize a particular drug is unpredictable. We intend generally to rely on the ability of our partners to provide access to the drugs that are to be formulated by us for deep lung delivery. There is a risk that our partners will not be able to provide access to such drug candidates. Even if such access is provided, there is a risk that our partners or we will be accused of, or determined to be, infringing a third-party's patent rights and will be prohibited from working with the drug or be found liable for damages that may not be subject to indemnification. Any such restriction on access to drug candidates or liability for damages would negatively impact our revenues and results of operations. OUR COMPETITORS MAY DEVELOP AND SELL BETTER DRUG DELIVERY SYSTEMS. We are aware of other companies engaged in developing and commercializing pulmonary drug delivery systems, including enhanced injectable and other drug delivery systems. Many of these companies have greater research and development capabilities, experience, manufacturing, marketing, financial and managerial resources than we do and represent significant competition for us. Acquisitions of or collaborations with competing drug delivery companies by large pharmaceutical companies could enhance our competitors' financial, marketing and other resources. Accordingly, our competitors may succeed in developing competing technologies, obtaining regulatory approval for products or gaining market acceptance before us. Developments by others could make our products or technologies uncompetitive or obsolete. Our competitors may introduce products or processes competitive with or superior to ours. INVESTORS SHOULD BE AWARE OF INDUSTRY-WIDE RISKS. In addition to the risks associated specifically with Inhale described above, investors should also be aware of general risks associated with drug development and the pharmaceutical industry. These include, but are not limited to: - changes in and compliance with government regulations; 10 - handling of hazardous materials; - hiring and retaining qualified people; and - insuring against product liability claims. WE EXPECT OUR STOCK PRICE TO REMAIN VOLATILE. Our stock price is volatile. In the twelve-month period ending January 11, 2001, based on closing prices on the Nasdaq National Market, our stock price ranged from $23.156 to $63.313. We expect it to remain volatile. A variety of factors may have a significant effect on the market price of our common stock, including: - fluctuations in our operating results; - announcements of technological innovations or new therapeutic products; - announcement or termination of collaborative relationships by Inhale or our competitors; - governmental regulation; - clinical trial results or product development delays; - developments in patent or other proprietary rights; - public concern as to the safety of drug formulations developed by Inhale or others; and - general market conditions. Any litigation brought against us as a result of this volatility could result in substantial costs and a diversion of our management's attention and resources, which could negatively impact our financial condition, revenues and results of operations. OUR SUBSTANTIAL INDEBTEDNESS MAY RESULT IN FUTURE LIQUIDITY PROBLEMS. As of September 30, 2000, we had approximately $242.6 million in long-term debt, and in October 2000, in connection with our build-to-suit lease transaction, we incurred an additional incremental lease liability, the present value of which approximates $46.2 million. Subsequent to Inhale's quarter ending September 30, 2000, the Company entered into privately negotiated agreements with certain holders of its outstanding 5.0% convertible subordinated notes due February 2007 providing for the conversion of their notes into shares of common stock in exchange for a cash payment. Approximately $168.6 million aggregate principal amount of such outstanding notes was converted into approximately 4.4 million shares of common stock for cash payments of approximately $25.5 million. The October 2000 issuance of the 3.5% convertible subordinated notes due 2007 increased our long term debt by approximately $230.0 million. This additional indebtedness has and will continue to impact us by: - increasing our interest expense and related debt service costs; - making it more difficult to obtain additional financing; and - constraining our ability to react quickly in an unfavorable economic climate. Currently, we are not generating sufficient cash flow from operations to satisfy the annual debt service payments that will be required as a result of the sale of the notes. This may require us to use a portion of the proceeds from the sale of the notes to pay interest or borrow additional funds or sell additional equity to meet out debt service obligations. If we are unable to satisfy our debt service requirements, substantial liquidity problems could result, which would negatively impact our future prospects. 11 THE NOTES ARE SUBORDINATED TO ANY EXISTING AND FUTURE SENIOR DEBT. The notes are contractually subordinated in right of payment to our existing and future Senior Debt. As of September 30, 2000, we had approximately $4.9 million of Senior Debt. In addition, in connection with a build-to-suit transaction completed in October 2000, we will incur incremental lease liability over a 16-year term, the present value of which approximates $46.2 million. This liability ranks senior to the notes. The indenture does not limit the creation of additional Senior Debt (or any other indebtedness). Any significant additional Senior Debt incurred may materially adversely impact our ability to service our debt, including the notes. Due to the subordination provisions, in the event of our insolvency, funds which we would otherwise use to pay the holders of the notes will be used to pay the holders of Senior Debt to the extent necessary to pay the Senior Debt in full. As a result of these payments, our general creditors may recover less, ratably, than the holders of our Senior Debt and such general creditors may recover more, ratably, than the holders of our notes or our other subordinated indebtedness. In addition, the holders of our Senior Debt may, under certain circumstances, restrict or prohibit us from making payments on the notes. OUR ABILITY TO REPURCHASE NOTES, IF REQUIRED, MAY BE LIMITED. In certain circumstances involving a Change of Control, the holders of the notes may require us to repurchase some or all of the holder's notes. We cannot assure you that we will have sufficient financial resources at such time or would be able to arrange financing to pay the repurchase price of the notes. Our ability to repurchase the notes in such event may be limited by law, the indenture, by the terms of other agreements relating to our Senior Debt and as such indebtedness and agreements may be entered into, replaced, supplemented or amended from time to time. We may be required to refinance our Senior Debt in order to make such payments. AN ACTIVE TRADING MARKET FOR THE NOTES MAY NOT DEVELOP. There is currently a limited trading market for the notes. Although the notes are eligible for trading in the PORTAL market, we cannot predict whether an active trading market for the notes will develop or be sustained. If an active market for the notes fails to develop or be sustained, the trading price of the notes could fall. If an active trading market were to develop, the notes could trade at prices that may be lower than the initial offering price of the notes. Whether or not the notes will trade at lower prices depends on many factors, including: - prevailing interest rates and the markets for similar securities; - general economic conditions; and - our financial condition, historic financial performance and future prospects. 12 WHERE YOU CAN FIND MORE INFORMATION We have filed with the SEC a registration statement on Form S-3 to register the notes and common stock offered by this prospectus.

The terms of the notes include those provided in the indenture and those provided in the registration rights agreement, which we entered into with the initial purchasers of the notes on October 17, 2000. The following description of provisions of the notes is not complete and is subject to, and qualified in its entirety by reference to, the notes, the indenture and the registration rights agreement. GENERAL The notes are general unsecured obligations of Inhale and rank junior in right of payment to all of our existing and future Senior Debt and are convertible into our common stock as described under "Conversion Rights" below. The notes will be limited to $230,000,000 aggregate principal amount and will mature on October 17, 2007, unless earlier redeemed by us or repurchased by us at the option of the holder upon the occurrence of a Change of Control (as defined below). The notes bear interest from October 17, 2000 at the rate of 3.5% per year, subject to adjustment upon the occurrence of a Reset Transaction. See "Interest Rate Adjustments" below. Interest is payable semi-annually on April 17 and October 17 of each year to holders of record at the close of business on the preceding April 2 and October 2, respectively, beginning April 17, 2001. We may pay interest on notes represented by certificated notes by check mailed to such holders. However, a holder of notes with an aggregate principal amount in excess of $5,000,000 will be paid by wire transfer in immediately available funds at the election of such holder. Interest will be computed on the basis of a 360-day year comprised of twelve 30-day months. Principal will be payable, and the notes may be presented for conversion, registration of transfer and exchange, without service charge, at our office or agency in New York City, which shall initially be the office or agency of the trustee in New York, New York. See "Form, Denomination and Registration" below. The indenture does not contain any financial covenants or any restrictions on the payment of dividends, the repurchase of our securities or the incurrence of Senior Debt or any other indebtedness. The indenture also does not contain any covenants or other provisions that afford protection to holders of notes in the event of a highly leveraged transaction or a Change in Control of Inhale except to the extent described under "Repurchase at Option of Holders Upon a Change of Control" below. INTEREST RATE ADJUSTMENTS If a Reset Transaction occurs, the interest rate will be adjusted to equal the Adjusted Interest Rate from the effective date of such Reset Transaction to, but not including, the effective date of any succeeding Reset Transaction. A "Reset Transaction" means: - a merger, consolidation or statutory share exchange to which the entity that is the issuer of the common stock into which the notes are then to be convertible into is a party; - a sale of all or substantially all the assets of that entity; - a recapitalization of that common stock; or - a distribution described in clause (4) of the fourth paragraph under "-Conversion Rights" below, after the effective date of which transaction or distribution the notes would be convertible into: - shares of an entity the common stock of which had a dividend yield for the four fiscal quarters of such entity immediately preceding the public announcement of the transaction or distribution 15 that was more than 2.5% higher than the dividend yield on our common stock (or other common stock then issuable upon conversion of the notes) for the four fiscal quarters preceding the public announcement of the transaction or distribution; or - shares of an entity that announces a dividend policy prior to the effective date of the transaction or distribution which policy, if implemented, would result in a dividend yield on that entity's common stock for the next four fiscal quarters that would result in such a 2.5% increase. The "Adjusted Interest Rate" with respect to any Reset Transaction will be the rate per year that is the arithmetic average of the rates quoted by two dealers engaged in the trading of convertible securities selected by us or our successor as the rate at which interest should accrue so that the fair market value, expressed in dollars, of a note immediately after the later of: - the public announcement of the Reset Transaction; or - the public announcement of a change in dividend policy in connection with the Reset Transaction, will equal the average Trading Price of a note for the 20 trading days preceding the date of public announcement of the Reset Transaction. However, the Adjusted Interest Rate will not be less than 5% per year. For purposes of the definition of Reset Transaction, the dividend yield on any security for any period means the dividends paid or proposed to be paid pursuant to an announced dividend policy on the security for that period divided by, if with respect to dividends paid on that security, the average Closing Price (as defined in the indenture) of the security during that period and, if with respect to dividends proposed to be paid on the security, the Closing Price of such security on the effective date of the related Reset Transaction. The "Trading Price" of a security on any date of determination means: - the closing sale price (or, if no closing sale price is reported, the last reported sale price) of a security (regular way) on the New York Stock Exchange ("NYSE") on that date; - if that security is not listed on the NYSE on that date, the closing sale price as reported in the composite transactions for the principal U.S. securities exchange on which that security is listed; - if that security is not so listed on a U.S. national or regional securities exchange, the closing sale price as reported by the Nasdaq National Market; - if that security is not so reported, the last price quoted by Interactive Data Corporation for that security or, if Interactive Data Corporation is not quoting such price, a similar quotation service selected by us; - if that security is not so quoted, the average of the mid-point of the last bid and ask prices for that security from at least two dealers recognized as market-makers for that security; or - if that security is not so quoted, the average of that last bid and ask prices for that security from a dealer engaged in the trading of convertible securities. FORM, DENOMINATION AND REGISTRATION The notes were issued in fully registered form, without coupons, in denominations of $1,000 principal amount and whole multiples of $1,000. GLOBAL NOTES: BOOK-ENTRY FORM. The notes were offered only to qualified institutional buyers as defined in Rule 144A under the Securities Act ("QIBs"). Except as provided below, the notes are and will continue to be evidenced by one or more global notes deposited with the trustee as custodian for 16 The Depository Trust Company, New York, New York ("DTC"), and registered in the name of Cede & Co. as DTC's nominee. The global notes and any notes issued in exchange therefore are subject to certain restrictions on transfer set forth in the global notes and in the indenture and bear a restrictive legend. Record ownership of the global notes may be transferred, in whole or in part, only to another nominee of DTC or to a successor of DTC or its nominee, except as set forth below. A QIB may hold its interests in a global note directly through DTC if such QIB is a participant in DTC, or indirectly through organizations which are direct DTC participants. Transfers between direct DTC participants will be effected in the ordinary way in accordance with DTC's rules and will be settled in same-day funds. QIBs may also beneficially own interests in the global notes held by DTC through certain banks, brokers, dealers, trust companies and other parties that clear through or maintain a custodial relationship with a direct DTC participant, either directly or indirectly. So long as Cede & Co., as nominee of DTC, is the registered owner of the global notes, Cede & Co. for all purposes will be considered the sole holder of the global notes. Except as provided below, owners of beneficial interests in the global notes will not be entitled to have certificates registered in their names, will not receive or be entitled to receive physical delivery of certificates in definitive form, and will not be considered holders thereof. The laws of some states require that certain persons take physical delivery of securities in definitive form. Consequently, the ability to transfer a beneficial interest in the global notes to such persons may be limited. We will wire, through the facilities of the trustee, principal, premium, if any, and interest payments on the global notes to Cede & Co., the nominee for DTC, as the registered owner of the global notes. Inhale, the trustee and any paying agent will have no responsibility or liability for paying amounts due on the global notes to owners of beneficial interests in the global notes. It is DTC's current practice, upon receipt of any payment of principal of and premium, if any, and interest on the global notes, to credit participants' accounts on the payment date in amounts proportionate to their respective beneficial interests in the notes represented by the global notes, as shown on the records of DTC, unless DTC believes that it will not receive payment on the payment date. Payments by DTC participants to owners of beneficial interests in notes represented by the global notes held through DTC participants will be the responsibility of DTC participants, as is now the case with securities held for the accounts of customers registered in "street name." If you would like to convert your notes into common stock pursuant to the terms of the notes, you should contact your broker or other direct or indirect DTC participant to obtain information on procedures, including proper forms and cut-off times, for submitting those requests. Because DTC can only act on behalf of DTC participants, who in turn act on behalf of indirect DTC participants and other banks, your ability to pledge your interest in the notes represented by global notes to persons or entities that do not participate in the DTC system, or otherwise take actions in respect of such interest, may be affected by the lack of a physical certificate. Neither Inhale nor the trustee (nor any registrar, paying agent or conversion agent under the indenture) will have any responsibility for the performance by DTC or direct or indirect DTC participants of their obligations under the rules and procedures governing their operations. DTC has advised us that it will take any action permitted to be taken by a holder of notes, including, without limitation, the presentation of notes for conversion as described below, only at the direction of one or more direct DTC participants to whose account with DTC interests in the global notes are credited and only for the principal amount of the notes for which directions have been given. DTC has advised us as follows: DTC is a limited purpose trust company organized under the laws of the State of New York, a member of the Federal Reserve System, a "clearing corporation" within the meaning of the Uniform Commercial Code and a "clearing agency" registered pursuant to the provisions of Section 17A of the Securities Exchange Act of 1934, as amended. DTC was created to 17 hold securities for DTC participants and to facilitate the clearance and settlement of securities transactions between DTC participants through electronic book-entry changes to the accounts of its participants, thereby eliminating the need for physical movement of certificates. Participants include securities brokers and dealers, banks, trust companies and clearing corporations and may include certain other organizations such as the initial purchasers of the notes. Certain DTC participants or their representatives, together with other entities, own DTC. Indirect access to the DTC system is available to others such as banks, brokers, dealers and trust companies that clear through, or maintain a custodial relationship with, a participant, either directly or indirectly. Although DTC has agreed to the foregoing procedures in order to facilitate transfers of interests in the global notes among DTC participants, it is under no obligation to perform or continue to perform such procedures, and such procedures may be discontinued at any time. If DTC is at any time unwilling or unable to continue as depositary and a successor depositary is not appointed by us within 90 days, we will cause notes to be issued in definitive form in exchange for the global notes. None of Inhale, the trustee or any of their respective agents will have any responsibility for the performance by DTC, direct or indirect DTC participants of their obligations under the rules and procedures governing their operations, including maintaining, supervising or reviewing the records relating to, or payments made on account of, beneficial ownership interests in global notes. According to DTC, the foregoing information with respect to DTC has been provided to its participants and other members of the financial community for informational purposes only and is not intended to serve as a representation, warranty or contract modification of any kind. CERTIFICATED NOTES. The notes represented by a global note will be exchangeable for notes in definitive form of like tenor as that global note in denominations of $1,000 and in any greater amount that is an integral multiple of $1,000 if: - DTC notifies us in writing that it is unwilling or unable to continue as depositary for that global note or if at any time DTC ceases to be a clearing agency registered under the Exchange Act and a successor depositary is not appointed by us within 90 days; - we, at our option, notify the trustee in writing that we elect to issue the notes in definitive form in exchange for all or any part of the notes represented by the global notes; or - there is, or continues to be, an event of default and the registrar has received a request from DTC for the issuance of the definitive notes in exchange for the global notes. Any note that is exchangeable pursuant to the preceding sentence is exchangeable for notes registered in the names which DTC will instruct the Trustee. It is expected that DTC's instructions may be based upon directions received by DTC from its participants with respect to ownership of beneficial interests in that global note. Subject to the foregoing, a global note is not exchangeable except for a global note or global notes of the same aggregate denominations to be registered in the name of the DTC participant or its nominee. RESTRICTIONS ON TRANSFER; LEGENDS. The notes are subject to certain transfer restrictions and certificates evidencing the notes bear a restrictive legend to such effect. CONVERSION RIGHTS The holders of notes may, at any time prior to the close of business on the final maturity date of the notes, convert any outstanding notes (or portions thereof) into our common stock, initially at the conversion price set forth on the cover page of this prospectus, subject to adjustment as described below. Holders may convert notes only in denominations of $1,000 and whole multiples of $1,000. Except as described below, no adjustment will be made on conversion of any notes for interest accrued thereon or dividends paid on any common stock. 18 If notes are converted after a record date for an interest payment but prior to the next interest payment date, those notes, other than notes called for redemption, must be accompanied by funds equal to the interest payable on the next interest payment date on the principal amount so converted. No payment will be required from a holder if we exercise our right to redeem such notes on a redemption date that is an interest payment date. We are not required to issue fractional shares of common stock upon conversion of notes and instead will pay a cash adjustment based upon the market price of our common stock on the last business day before the date of the conversion. In the case of notes called for redemption, conversion rights will expire at the close of business on the second business day preceding the date fixed for redemption, unless we default in payment of the redemption price. A holder may exercise the right of conversion by delivering the note to be converted to the specified office of a conversion agent, with a completed notice of conversion, together with any funds that may be required as described in the preceding paragraph. The conversion date will be the date on which the notes, the notice of conversion and any required funds have been so delivered. A holder delivering a note for conversion will not be required to pay any taxes or duties relating to the issuance or delivery of the common stock for such conversion, but will be required to pay any tax or duty which may be payable relating to any transfer involved in the issuance or delivery of the common stock in a name other than the holder of the note. Certificates representing shares of common stock will be issued or delivered only after all applicable taxes and duties, if any, payable by the holder have been paid. If any note is converted within two years after its original issuance, the common stock issuable upon conversion will not be issued or delivered in a name other than that of the holder of the note unless the applicable restrictions on transfer have been satisfied. The initial conversion price will be adjusted for certain events, including: 1) the issuance of our common stock as a dividend or distribution on our common stock; 2) certain subdivisions and combinations of our common stock; 3) the issuance to all holders of our common stock of certain rights or warrants to purchase our common stock (or securities convertible into our common stock) at less than (or having a conversion price per share less than) the current market price of our common stock; 4) the dividend or other distribution to all holders of our common stock or shares of our capital stock (other than common stock) or evidences of our indebtedness or our assets (including securities, but excluding those rights and warrants referred to above and dividends and distributions in connection with a reclassification, change, consolidation, merger, combination, sale or conveyance resulting in a change in the conversion consideration pursuant to the second succeeding paragraph or dividends or distributions paid exclusively in cash); 5) dividends or other distributions consisting exclusively of cash to all holders of our common stock to the extent that such distributions, combined together with (A) all other such all-cash distributions made within the preceding 12 months for which no adjustment has been made plus (B) any cash and the fair market value of other consideration paid for any tender offers by us or any of our subsidiaries for our common stock concluded within the preceding 12 months for which no adjustment has been made, exceeds 10% of our market capitalization on the record date for such distribution; market capitalization is the product of the then current market price of our common stock times the number of shares of our common stock then outstanding; and 6) the purchase of our common stock pursuant to a tender offer made by us or any of our subsidiaries to the extent that the same involves an aggregate consideration that, together with (A) any cash and the fair market value of any other consideration paid in any other tender offer by us or any of our subsidiaries for our common stock expiring within the 12 months 19 preceding such tender offer for which no adjustment has been made plus (B) the aggregate amount of any all-cash distributions referred to in clause (5) above to all holders of our common stock within 12 months preceding the expiration of tender offer for which no adjustments have been made, exceeds 10% of our market capitalization on the expiration of such tender offer. No adjustment in the conversion price will be required unless such adjustment would require a change of at least 1% in the conversion price then in effect at such time. Any adjustment that would otherwise be required to be made shall be carried forward and taken into account in any subsequent adjustment. Except as stated above, the conversion price will not be adjusted for the issuance of our common stock or any securities convertible into or exchangeable for our common stock or carrying the right to purchase any of the foregoing. In the case of: - any reclassification or change of our common stock (other than changes resulting from a subdivision or combination) or - a consolidation, merger or combination involving us or a sale or conveyance to another corporation of all or substantially all of our property and assets, in each case as a result of which holders of our common stock are entitled to receive stock, other securities, other property or assets (including cash or any combination thereof) with respect to or in exchange for our common stock, the holders of the notes then outstanding will be entitled thereafter to convert those notes into the kind and amount of shares of stock, other securities or other property or assets (including cash or any combination thereof) which they would have owned or been entitled to receive upon such reclassification, change, consolidation, merger, combination, sale or conveyance had such notes been converted into our common stock immediately prior to such reclassification, change, consolidation, merger, combination, sale or conveyance. We may not become a party to any such transaction unless its terms are consistent with the foregoing. If a taxable distribution to holders of our common stock or other transaction occurs which results in any adjustment of the conversion price, the holders of notes may, in certain circumstances, be deemed to have received a distribution subject to U.S. income tax as a dividend. In certain other circumstances, the absence of an adjustment may result in a taxable dividend to the holders of common stock. See "Certain United States Federal Income Tax Considerations." We may from time to time, to the extent permitted by law, reduce the conversion price of the notes by any amount for any period of at least 20 days. In that case we will give at least 15 days' notice of such decrease. We may make such reductions in the conversion price, in addition to those set forth above, as our board of directors deems advisable to avoid or diminish any income tax to holders of our common stock resulting from any dividend or distribution of stock (or rights to acquire stock) or from any event treated as such for income tax purposes. PROVISIONAL REDEMPTION We may redeem the notes, in whole or in part, at any time prior to October 17, 2003, at a redemption price equal to $1,000 per $1,000 principal amount of notes to be redeemed if the closing price of our common stock has exceeded 150% of the conversion price then in effect for at least 20 trading days within a period of 30 consecutive trading days ending on the trading day prior to the date of mailing of the provisional redemption notice (which date shall be not less than 20 nor more then 60 trading days prior to the provisional redemption date). Upon any provisional redemption, we will make an additional payment with respect to the notes called for redemption to holders on the notice date in an amount equal to $105.00 per $1,000 principal 20 amount of notes, less the amount of any interest actually paid on the notes prior to the provisional redemption date. We may make this additional payment, at our option, either in cash or in our common stock or a combination of cash and common stock, if such common stock has been registered under the Securities Act and we state in our notice that we expect such registration to remain effective and available for use for the 30 days following the provisional redemption date (if registration is required and if we satisfy certain other conditions specified in the indenture). We will specify the type of consideration for the additional payment in the redemption notice. Payments made in our common stock will be valued at 97% of the average of the closing sales prices of our common stock for the five trading days ending on the day prior to the provisional redemption date. We will be obligated to make this additional payment on all notes called for provisional redemption, including any notes converted after the notice date and before the provisional redemption date. OPTIONAL REDEMPTION BY INHALE Except as set forth above under the "Provisional Redemption", the notes are not redeemable prior to October 17, 2003. At any time on or after that date, we may redeem some or all of the notes on at least 20 but not more than 60 days' notice, at the following prices (expressed in percentages of the principal amount), together with accrued and unpaid interest to, but excluding, the date fixed for redemption, if the closing price of our common stock has exceeded 120% of the conversion price then in effect for at least 20 trading days within a period of 30 consecutive trading days ending on the trading day immediately prior to the date of mailing of the optional redemption notice. However, if a redemption date is an interest payment date, the semi-annual payment of interest becoming due on such date shall be payable to the holder of record as of the relevant record date and the redemption price shall not include such interest payment.
DURING THE TWELVE MONTHS COMMENCING REDEMPTION PRICE - ----------------------------------- ---------------- October 17, 2003............................................ 102.00% October 17, 2004............................................ 101.50% October 17, 2005............................................ 101.00% October 17, 2006............................................ 100.50%
If we do not redeem all of the notes, the trustee will select the notes to be redeemed in principal amounts of $1,000 or whole multiples of $1,000 by lot or on a pro rata basis. If any notes are to be redeemed in part only, a new note or notes in principal amount equal to the unredeemed principal portion thereof will be issued. If a portion of a holder's notes is selected for partial redemption and the holder converts a portion of its notes, the converted portion will be deemed to be taken from the portion selected for redemption. No sinking fund is provided for the notes. REPURCHASE AT OPTION OF HOLDERS UPON A CHANGE OF CONTROL If a Change of Control occurs, each holder of notes will have the right to require us to repurchase all of that holder's notes not previously called for redemption, or any portion of those notes that is equal to $1,000 or a whole multiple of $1,000, on the date that is 45 days after the date we give notice at a repurchase price equal to 100% of the principal amount of the notes to be repurchased, together with interest accrued and unpaid to, but excluding, the repurchase date. Instead of paying the repurchase price in cash, we may pay the repurchase price in common stock. The number of shares of common stock a holder will receive will equal the repurchase price divided by 95% of the average of the closing sales prices of our common stock for the five trading days immediately preceding and including the third day prior to the repurchase date. However, we may not 21 pay in common stock unless we satisfy certain conditions prior to the repurchase date as provided in the indenture. Within 30 days after the occurrence of a Change of Control, we are required to give notice to all holders of notes, as provided in the indenture, of the occurrence of the Change of Control and of their resulting repurchase right. We must also deliver a copy of our notice to the trustee. To exercise the repurchase right, a holder of notes must deliver prior to or on the 30th day after the date of our notice irrevocable written notice to the trustee of the holder's exercise of its repurchase right, together with the notes with respect to which the right is being exercised. A "Change of Control" will be deemed to have occurred at such time after the original issuance of the notes when the following has occurred: - the acquisition by any person, including any syndicate or group deemed to be a "person" under Section 13(d)(3) of the Securities Exchange Act of 1934, as amended (the "Exchange Act"), of beneficial ownership, directly or indirectly, through a purchase, merger or other acquisition transaction or series of transactions of shares of our capital stock entitling that person to exercise 50% or more of the total voting power of all shares of our capital stock entitled to vote generally in elections of directors, other than any acquisition by us, any of our subsidiaries or any of our employee benefit plans; or - our consolidation or merger with or into any other person, any merger of another person into us, or any conveyance, transfer, sale, lease or other disposition of all or substantially all of our properties and assets to another person, other than: 1) any transaction (A) that does not result in any reclassification, conversion, exchange or cancellation of outstanding shares of our capital stock and (B) pursuant to which holders of our capital stock immediately prior to the transaction have the entitlement to exercise, directly or indirectly, 50% or more of the total voting power of all shares of our capital stock entitled to vote generally in the election of directors of the continuing or surviving person immediately after the transaction; and 2) any merger solely for the purpose of changing our jurisdiction of incorporation and resulting in a reclassification, conversion or exchange of outstanding shares of common stock solely into shares of common stock of the surviving entity. However, a Change of Control will not be deemed to have occurred if the closing sales price per share of our common stock for any five trading days within the period of 10 consecutive trading days ending immediately after the later of the Change of Control or the public announcement of the Change of Control, in the case of a Change of Control under the first clause above, or the period of 10 consecutive trading days ending immediately before the Change of Control, in the case of a Change of Control under the second clause above, equals or exceeds 110% of the conversion price of the notes in effect on each such trading day. The beneficial owner shall be determined in accordance with Rule 13d-3 promulgated by the SEC under the Exchange Act. The term "person" includes any syndicate or group which would be deemed to be a "person" under Section 13(d)(3) of the Exchange Act. Rule 13e-4 under the Exchange Act, as amended, requires the dissemination of certain information to security holders if an issuer tender offer occurs and may apply if the repurchase option becomes available to holders of the notes. We will comply with this rule to the extent applicable at that time. We may, to the extent permitted by applicable law, at any time purchase the notes in the open market or by tender at any price or by private agreement. Any note so purchased by us may, to the extent permitted by applicable law, be reissued or resold or may be surrendered to the trustee for cancellation. Any notes surrendered to the trustee may not be reissued or resold and will be canceled promptly. 22 The foregoing provisions would not necessarily protect holders of the notes if highly leveraged or other transactions involving us occur that may adversely affect holders. Our ability to repurchase notes upon the occurrence of a Change in Control is subject to important limitations. The occurrence of a Change in Control could cause an event of default under, or be prohibited or limited by, the terms of Senior Debt that we may incur in the future. As a result, any repurchase of the notes would, absent a waiver, be prohibited under the subordination provisions of the indenture until the Senior Debt is paid in full. Further, we cannot assure you that we would have the financial resources, or would be able to arrange financing, to pay the repurchase price for all the notes that might be delivered by holders of notes seeking to exercise the repurchase right. Any failure by us to repurchase the notes when required following a Change in Control would result in an event of default under the indenture, whether or not such repurchase is permitted by the subordination provisions of the indenture. Any such default may, in turn, cause a default under Senior Debt that we may incur in the future. See "-Subordination" below. SUBORDINATION The notes are subordinated in right of payment to the prior payment in full of all our existing and future Senior Debt. The indenture provides that in the event of any distribution of our assets upon our dissolution, winding up, liquidation or reorganization, the holders of our Senior Debt shall first be paid in respect of all Senior Debt in full in cash or other payment satisfactory to the holders of Senior Debt before we make any payments of principal of, or premium, if any, and interest (including liquidated damages, if any) on the notes. In addition, if the notes are accelerated because of an event of default, the holders of any Senior Debt would be entitled to payment in full in cash or other payment satisfactory to the holders of Senior Debt of all obligations in respect of Senior Debt before the holders of the notes are entitled to receive any payment or distribution. Under the indenture, we must promptly notify holders of Senior Debt if payment of the notes is accelerated because of an event of default. The indenture further provides if any default by us has occurred and is continuing in the payment of principal of or premium, if any, or interest on, rent or other payment obligations in respect of, any Senior Debt, then no payment shall be made on account of principal of, premium, if any, or interest on the notes (including any liquidated damages), until all such payments due in respect of that Senior Debt have been paid in full in cash or other payment satisfactory to the holders of that Senior Debt. During the continuance of any event of default with respect to any Designated Senior Debt (other than a default in payment of the principal of or premium, if any, or interest on, rent or other payment obligations in respect of any Designated Senior Debt), permitting the holders thereof to accelerate the maturity thereof (or, in the case of any lease, permitting the landlord either to terminate the lease or to require us to make an irrevocable offer to terminate the lease following an event of default thereunder), no payment may be made by us, directly or indirectly, with respect to principal of or premium, if any, or interest on the notes (including any liquidated damages, if any) for 179 days following written notice to us, from any holder, representative or trustee under any agreement pursuant to which that Designated Senior Debt may have been issued, that such an event of default has occurred and is continuing, unless such event of default has been cured or waived or that Designated Senior Debt has been paid in full in cash or other payment satisfactory to the holders of that Designated Senior Debt. However, if the maturity of that Designated Senior Debt is accelerated (or, in the case of a lease, as a result of such events of default, the landlord under the lease has given us notice of its intention to terminate the lease or to require us to make an irrevocable offer to terminate the lease following an event of default thereunder), no payment may be made on the notes until that Designated Senior Debt has been paid in full in cash or other payment satisfactory to the holders of that Designated Senior Debt or such acceleration (or termination, in the case of the lease) has been cured or waived. 23 By reason of such subordination provisions, in the event of insolvency, funds which we would otherwise use to pay the holders of notes will be used to pay the holders of Senior Debt to the extent necessary to pay Senior Debt in full in cash or other payment satisfactory to the holders of Senior Debt. As a result of these payments, our general creditors may recover less, ratably, than holders of Senior Debt and such general creditors may recover more, ratably, than holders of notes. "Senior Debt" means the principal of, premium, if any, interest (including all interest accruing subsequent to the commencement of any bankruptcy or similar proceeding, whether or not a claim for post-petition interest is allowable as a claim in any such proceeding) and rent payable on or termination payment with respect to or in connection with, and all fees, costs, expenses and other amounts accrued or due on or in connection with, our Indebtedness, whether outstanding on the date of the indenture or subsequently created, incurred, assumed, guaranteed or in effect guaranteed by us (including all deferrals, renewals, extensions or refunding of, or amendments, modifications or supplements to, the foregoing), unless in the case of any particular Indebtedness, the instrument creating or evidencing such Indebtedness or the assumption or guarantee thereof expressly provides that that Indebtedness shall not be senior in right of payment to the notes or expressly provides that such Indebtedness is equal with or junior to the notes. The notes shall not be senior in right of payment to the outstanding 6( 3)/(4)% convertible subordinated debentures due October 2006 or 5% convertible subordinated notes due February 2007 and shall be equal with such debentures and notes. The term "Senior Debt" shall also include all Designated Senior Debt and shall not include our Indebtedness to any of our subsidiaries of which we own, directly or indirectly, a majority of the voting stock. "Indebtedness" means, with respect to any person: 1) all indebtedness, obligations and other liabilities (contingent or otherwise) of that person for borrowed money (including obligations in respect of overdrafts, foreign exchange contracts, currency exchange agreements, interest rate protection agreements, and any loans or advances from banks, whether or not evidenced by notes or similar instruments) or evidenced by bonds, debentures, notes or other instruments for the payment of money, or incurred in connection with the acquisition of any property, services or assets (whether or not the recourse of the lender is to the whole of the assets of such person or to only a portion thereof), other than any account payable or other accrued current liability or obligation to trade creditors incurred in the ordinary course of business in connection with the obtaining of materials or services; 2) all reimbursement obligations and other liabilities (contingent or otherwise) of that person with respect to letters of credit, bank guarantees, bankers' acceptances, surety bonds, performance bonds or other guaranty of contractual performance; 3) all obligations and liabilities (contingent or otherwise) in respect of (A) leases of such person required, in conformity with generally accepted accounting principles, to be accounted for as capitalized lease obligations on the balance sheet of such person, and (B) any lease or related documents (including a purchase agreement) in connection with the lease of real property which provides that such person is contractually obligated to purchase or cause a third party to purchase the leased property and thereby guarantee a minimum residual value of the leased property to the landlord and the obligations of such person under such lease or related document to purchase or to cause a third party to purchase the leased property; 4) all obligations of such person (contingent or otherwise) with respect to an interest rate or other swap, cap or collar agreement or other similar instrument or agreement or foreign currency hedge, exchange, purchase or similar instrument or agreement; 24 5) all direct or indirect guaranties or similar agreements by that person in respect of, and obligations or liabilities (contingent or otherwise) of that person to purchase or otherwise acquire or otherwise assure a creditor against loss in respect of, indebtedness, obligations or liabilities of another person of the kind described in clauses (1) through (4); 6) any indebtedness or other obligations described in clauses (1) through (4) secured by any mortgage, pledge, lien or other encumbrance existing on property which is owned or held by such person, regardless of whether the indebtedness or other obligation secured thereby shall have been assumed by such person; and 7) any and all deferrals, renewals, extensions and refundings of, or amendments, modifications or supplements to, any indebtedness, obligation or liability of the kind described in clauses (1) through (6). "Designated Senior Debt" means our Senior Debt which, at the date of determination, has an aggregate amount outstanding of, or under which, at the date of determination, the holders thereof are committed to lend up to, at least $25 million and is specifically designated in the instrument evidencing or governing that Senior Debt as "Designated Senior Debt" for purposes of the indenture. However, the instrument may place limitations and conditions on the right of that Senior Debt to exercise the rights of Designated Senior Debt. We had approximately $4.9 million of Senior Debt and no Designated Senior Debt at September 30, 2000. In addition, in connection with our build-to-suit lease transaction described under "Management's Discussion and Analysis of Financial Condition and Results of Operations--Liquidity and Capital Resources," we will incur incremental lease liability over a 16 year term, the present value of which approximates $46.2 million. This liability ranks senior to the notes. There are no restrictions in the indenture on the creation of Senior Debt or any other indebtedness in the future. The notes are our obligations exclusively and will be, in effect, subordinated to all Indebtedness (including trade payables) of any subsidiaries that we own in the future. The indenture does not limit the amount of Indebtedness or other liabilities any future subsidiaries may incur. Our ability to make required interest, principal, repurchase, cash conversion or redemption payments on the notes may be impaired as a result of the obligations of any future subsidiaries. Any future subsidiaries would be separate and distinct legal entities and would have no obligation, contingent or otherwise, to pay any amounts due pursuant to the notes or to make any funds available therefore, whether by dividends, loans or other payments. Any right we have to receive assets of any of our future subsidiaries upon the latter's liquidation or reorganization (and the consequent right of the holders of the notes to participate in those assets) will be effectively subordinated to the claims of that subsidiary's creditors, except to the extent that we are ourselves recognized as a creditor of that subsidiary, in which case our claims would still be subordinate to any security interests in the assets of that subsidiary and any indebtedness of that subsidiary senior to that held by us. There are no restrictions in the indenture on the ability of any of our future subsidiaries to incur Indebtedness or other liabilities. We are obligated to pay reasonable compensation to the trustee and to indemnify the trustee against any losses, liabilities or expenses incurred by it in connection with its duties relating to the notes. The trustee's claims for such payments will be senior to those of holders of the notes in respect of all funds collected or held by the trustee. EVENTS OF DEFAULT Each of the following constitutes an event of default under the indenture: 1) our failure to pay when due the principal of or premium, if any, on any of the notes at maturity, upon redemption or exercise of a repurchase right or otherwise, whether or not such payment is prohibited by the subordination provisions of the indenture; 25 2) our failure to pay an installment of interest (including liquidated damages, if any) on any of the notes for 30 days after the date when due, whether or not such payment is prohibited by the subordination provisions of the indenture; 3) our failure to perform or observe any other term, covenant or agreement contained in the notes or the indenture for a period of 60 days after written notice of such failure, requiring us to remedy the same, shall have been given to us by the trustee or to us and the trustee by the holders of at least 25% in aggregate principal amount of the notes then outstanding; 4) our failure to make any payment by the end of the applicable grace period, if any, after the maturity of any Indebtedness for borrowed money in an amount in excess of $5 million (PROVIDED that such failure will not constitute an event of default if (1) we determine, in good faith, that a lessor under a lease described in clause (3)(A) of the definition of Indebtedness set forth under "-Subordination" (that is, a sale/leaseback transaction) breached a covenant under the lease and we give notice of the breach to the lessor and the trustee and (2) as a result of the breach, we withhold payment under the lease) (a "Default Exception"), or the acceleration of Indebtedness for borrowed money in an amount in excess of $5 million because of a default with respect to such Indebtedness (other than a Default Exception) without such Indebtedness having been discharged or such acceleration having been cured, waived, rescinded or annulled, in either case, for a period of 30 days after written notice to us by the trustee or to us and the trustee by holders of at least 25% in aggregate principal amount of the notes then outstanding; and 5) certain events of our bankruptcy, insolvency or reorganization. The indenture provides that the trustee shall, within 90 days of the occurrence of a default, give to the registered holders of the notes notice of all uncured defaults known to it, but the trustee shall be protected in withholding such notice if it, in good faith, determines that the withholding of such notice is in the best interest of such registered holders, except in the case of a default in the payment of the principal of, or premium, if any, or interest on, any of the notes when due or in the payment of any redemption or repurchase obligation. If an event of default specified in clause (5) above occurs and is continuing, then automatically the principal of all the notes and the interest thereon shall become immediately due and payable. If an event of default shall occur and be continuing, other than with respect to clause (5) above (the default not having been cured or waived as provided under "-Meetings, Modifications and Waiver" below), the trustee or the holders of at least 25% in aggregate principal amount of the notes then outstanding may declare the notes due and payable at their principal amount together with accrued interest, and thereupon the trustee may, at its discretion, proceed to protect and enforce the rights of the holders of notes by appropriate judicial proceedings. Such declaration may be rescinded or annulled either with the written consent of the holders of a majority in aggregate principal amount of the notes then outstanding or a majority in aggregate principal amount of the notes represented at a meeting at which a quorum (as specified under "-Meetings, Modifications and Waiver" below) is present, in each case upon the conditions provided in the indenture. The indenture contains a provision entitling the trustee, subject to the duty of the trustee during default to act with the required standard of care, to be indemnified by the holders of notes before proceeding to exercise any right or power under the indenture at the request of such holders. The indenture provides that the holders of a majority in aggregate principal amount of the notes then outstanding through their written consent, or the holders of a majority in aggregate principal amount of the notes then outstanding represented at a meeting at which a quorum is present by a written resolution, may direct the time, method and place of conducting any proceeding for any remedy available to the trustee or exercising any trust or power conferred upon the trustee. 26 We are required to furnish annually to the trustee a statement as to the fulfillment of our obligations under the indenture. CONSOLIDATION, MERGER OR ASSUMPTION We may, without the consent of the holders of notes, consolidate with, merge into or transfer all or substantially all of our assets to any other corporation organized under the laws of the United States or any of its political subdivisions provided that: - the surviving corporation assumes all our obligations under the indenture and the notes; - at the time of such transaction, no event of default, and no event which, after notice or lapse of time, would become an event of default, shall have happened and be continuing; and - certain other conditions are met. MEETINGS, MODIFICATIONS AND WAIVER The indenture contains provisions for convening meetings of the holders of notes to consider matters affecting their interests. The indenture (including the terms and conditions of the notes) may be modified or amended by us and the trustee, without the consent of the holder of any note, for the purposes of, among other things: - adding to our covenants for the benefit of the holders of notes; - surrendering any right or power conferred upon us; - providing for conversion rights of holders of notes if any reclassification or change of our common stock or any consolidation, merger or sale of all or substantially all of our assets occurs; - providing for the assumption of our obligations to the holders of notes in the case of a merger, consolidation, conveyance, transfer or lease; - reducing the conversion price, provided that the reduction will not adversely affect the interests of holders of notes in any material respect; - complying with the requirements of the SEC in order to effect or maintain the qualification of the indenture under the Trust Indenture Act of 1939, as amended; - making any changes or modification to the indenture necessary in connection with the registration of the notes under the Securities Act as contemplated by the registration rights agreement, provided that this action does not adversely affect the interest of the holders of the notes in any material respects; - curing any ambiguity or correcting or supplementing any defective provision contained in the indenture; provided that such modification or amendment does not, in the good faith opinion of our board of directors and the trustee, adversely affect the interests of the holders of the notes in any material respect; or - adding or modifying any other provisions which we and the trustee may deem necessary or desirable and which will not adversely affect the interests of the holders of notes in any material respect. 27 Modifications and amendments to the indenture or to the terms and conditions of the notes may also be made, and past default by us may be waived, either: - with the written consent of the holders of at least a majority in aggregate principal amount of the notes at the time outstanding; or - by the adoption of a resolution at a meeting of holders by at least a majority in aggregate principal amount of the notes represented at such meeting. However, no such modification, amendment or waiver may, without the written consent or the affirmative vote of the holder of each note so affected: - change the maturity of the principal of or any installment of interest on that note (including any payment of liquidated damages); - reduce the principal amount of, or any premium or interest on (including any payment of liquidated damages), any note; - change the currency of payment of such note or interest thereon; - impair the right to institute suit for the enforcement of any payment on or with respect to any note; - modify our obligations to maintain an office or agency in New York City; - except as otherwise permitted or contemplated by provisions concerning corporate reorganizations, adversely affect the repurchase option of holders upon a Change of Control or the conversion rights of holders of the notes; - modify the subordination provisions of the notes in a manner adverse to the holders of notes; - reduce the percentage in aggregate principal amount of notes outstanding necessary to modify or amend the indenture or to waive any past default; or - reduce the percentage in aggregate principal amount of notes outstanding required for the adoption of a resolution or the quorum required at any meeting of holders of notes at which a resolution is adopted. The quorum at any meeting called to adopt a resolution will be persons holding or representing a majority in aggregate principal amount of the notes at the time outstanding and, at any reconvened meeting adjourned for lack of a quorum, 25% of that aggregate principal amount. SATISFACTION AND DISCHARGE We may discharge our obligations under the indenture while notes remain outstanding, subject to certain conditions, if - all outstanding notes will become due and payable at their scheduled maturity, within one year; or - all outstanding notes are scheduled for redemption within one year, and, in either case, we have deposited with the trustee an amount sufficient to pay and discharge all outstanding notes on the date of their scheduled maturity or the scheduled date of redemption. GOVERNING LAW The indenture and the notes are governed by, and construed in accordance with, the law of the State of New York. 28 INFORMATION CONCERNING THE TRUSTEE Chase Manhattan Bank and Trust Company, National Association, as trustee under the indenture, has been appointed by us as paying agent, conversion agent, registrar and custodian with regard to the notes. ChaseMellon Shareholder Services LLC is the transfer agent and registrar for our common stock. The trustee or its affiliates may from time to time in the future provide banking and other services to us in the ordinary course of their business. REGISTRATION RIGHTS We have, at our expense, filed with the SEC not later than the date 90 days after the earliest date of original issuance of any of the notes, subject to certain conditions set forth below, a shelf registration statement on Form S-3 covering resales by holders of the notes and the common stock issuable upon conversion of the notes. Under the terms of the registration rights agreement we have agreed to use our best efforts to: - cause the registration statement to become effective as promptly as is practicable, but in no event later than 180 days after the earliest date of original issuance of any of the notes; and - keep the registration statement effective until such date that is two years after the last date of original issuance of any of the notes (or such earlier date when the holders of the notes and the common stock issuable upon conversion of the notes are able to sell all such securities immediately without restriction pursuant to the volume limitation provisions of Rule 144 under the Securities Act or any successor rule thereto or otherwise). We have also agreed to provide to each registered holder copies of the prospectus, notify each registered holder when the shelf registration statement has become effective and take certain other actions as are required to permit unrestricted resales of the notes and the common stock issuable upon conversion of the notes. A holder who sells those securities pursuant to the shelf registration statement generally will be required to be named as a selling stockholder in the related prospectus and to deliver a prospectus to purchasers and will be bound by the provisions of the registration rights agreement, which are applicable to that holder (including certain indemnification provisions). If a shelf registration statement covering those securities is not effective, they may not be sold or otherwise transferred except pursuant to an exemption from registration under the Securities Act and any other applicable securities laws or in a transaction not subject to those laws. Each holder must notify us not later than three business days prior to any proposed sale by that holder pursuant to the shelf registration statement. This notice will be effective for five business days. We may suspend the holder's use of the prospectus for a reasonable period not to exceed 45 days (60 days under certain circumstances relating to a proposed or pending material business transaction, the disclosure of which would impede our ability to consummate such transaction) in any 90-day period, and not to exceed an aggregate of 90 days in any 12-month period, if we, in our reasonable judgment, believe we may possess material non-public information the disclosure of which would have a material adverse effect on us and our subsidiaries taken as a whole. Each holder, by its acceptance of a note, agrees to hold any communication by us in response to a notice of a proposed sale in confidence. If, - on the 180th day following the earliest date of original issuance of any of the notes, the shelf registration statement is not declared effective; or - the registration statement shall cease to be effective or fail to e usable without being succeeded within five business days by a post-effective amendment or a report filed with the SEC pursuant to the Exchange Act that cures the failure of the registration statement to be effective or usable; or 29 - on the 45th or 60th day, as the case may be, of any period that the prospectus has been suspended as described in the preceding paragraph, such suspension has not been terminated (each, a "registration default"), additional interest as liquidated damages will accrue on the notes, from and including the day following the registration default to but excluding the day on which the registration default has been cured. Liquidated damages will be paid semi-annually in arrears, with the first semi-annual payment due on the first interest payment date, as applicable, following the date on which such liquidated damages begin to accrue, and will accrue at a rate per year equal to: - an additional 0.25% of the principal amount to and including the 90th day following such registration default; and - an additional 0.5% of the principal amount from and after the 91st day following such registration default. In no event will liquidated damages accrue at a rate per year exceeding 0.5%. If a holder has converted some or all of its notes into common stock, the holder will be entitled to receive equivalent amounts based on the principal amount of the notes converted. We agreed to distribute a questionnaire to each holder to obtain certain information regarding the holder for inclusion in the prospectus. Holders were required to complete and deliver the questionnaire within 20 business days after receipt of the questionnaire to be named as selling stockholders in the related prospectus at the time of effectiveness. A holder will not be entitled to liquidated damages unless it has provided all information requested by the questionnaire prior to the deadline. The specific provisions relating to the registration described above are contained in the registration rights agreement which was entered into on the closing of the initial offering of the notes. DESCRIPTION OF CAPITAL STOCK The following description of our capital stock and certain provisions of our certificate of incorporation and bylaws is a summary and is qualified in its entirety by the provisions of our certificate of incorporation and bylaws. Our authorized capital stock consists of 300,000,000 shares of common stock, and 10,000,000 shares of preferred stock. COMMON STOCK As of January 2, 2001, there were 47,374,459 shares of our common stock outstanding. The holders of common stock are entitled to one vote for each share held of record on all matters submitted to a vote of the stockholders. The holders of common stock are not entitled to cumulative voting rights with respect to the election of directors, and as a consequence, minority stockholders are not able to elect directors on the basis of their votes alone. Subject to preferences that may be applicable to any shares of preferred stock issued in the future, holders of common stock are entitled to receive ratably such dividends as may be declared by the Board of Directors out of funds legally available therefore. In the event of a liquidation, dissolution or winding up of Inhale, holders of the common stock are entitled to share ratably in all assets remaining after payment of liabilities and the liquidation preference of any then outstanding preferred stock. Holders of common stock have no preemptive rights and no right to convert their common stock into any other securities. There are no redemption or sinking fund provisions applicable to the common stock. PREFERRED STOCK The Board of Directors has the authority, without further action by the stockholders, to issue up to 10,000,000 shares of preferred stock in one or more series and to fix the rights, preferences, privileges and restrictions thereof, including dividend rights, conversion rights, voting rights, terms of redemption, liquidation preferences, sinking fund terms and the number of shares constituting any series or the 30 designation of such series, without any further vote or action by stockholders. The issuance of preferred stock could adversely affect the voting power of holders of common stock and the likelihood that such holders will receive dividend payments and payments upon liquidation and could have the effect of delaying, deferring or preventing a change in control. We have no present plan to issue any shares of preferred stock. REGISTRATION RIGHTS Pfizer has the right to include shares of our common stock purchased pursuant to the purchase agreement relating to its equity investment in the first firmly underwritten public offering of our common stock effected after January 18, 2000. We are required to pay all expenses in connection with such registration, excluding the fees of counsel for Pfizer. ANTI-TAKEOVER EFFECTS OF PROVISIONS OF OUR CHARTER AND BYLAWS Our certificate of incorporation provides for the Board of Directors to be divided into three classes, with staggered three-year terms. As a result, only one class of directors will be elected at each annual meeting of stockholders, with the other classes continuing for the remainder of their respective three-year terms. Stockholders have no cumulative voting rights, and the stockholders representing a majority of the shares of common stock outstanding are able to elect all of the directors. Our certificate of incorporation also requires that any action required or permitted to be taken by our stockholders must be effected at a duly called annual or special meeting of the stockholders and may not be effected by a consent in writing and that the stockholders may amend our bylaws or adopt new bylaws, only by the affirmative vote of 66 2/3% of the outstanding voting securities. A special meeting of the stockholders may be called by the Chairman, the Chief Executive Officer, or by a resolution adopted by a majority of the total number of authorized directors or stockholders owning 10% or more of the outstanding voting capital stock. These provisions may have the effect of delaying, deferring or preventing a change in control. The classification of the Board of Directors and lack of cumulative voting will make it more difficult for our existing stockholders to replace the Board of Directors as well as for another party to obtain control of Inhale by replacing the Board of Directors. Since the Board of Directors has the power to retain and discharge our officers, these provisions could also make it more difficult for existing stockholders or another party to effect a change in management. These and other provisions may have the effect of deterring hostile takeovers or delaying changes in control or management. These provisions are intended to enhance the likelihood of continued stability in the composition of the Board of Directors and in the policies of the Board of Directors and to discourage certain types of transactions that may involve an actual or threatened change in control. These provisions are designed to reduce our vulnerability to an unsolicited acquisition proposal. The provisions also are intended to discourage certain tactics that may be used in proxy rights. However, such provisions could have the effect of discouraging others from making tender offers for our shares and, as a consequence, they also may inhibit fluctuations in the market price of the our shares that could result from actual or rumored takeover attempts. Such provisions also may have the effect of preventing changes in our management. SECTION 203 OF THE DELAWARE GENERAL CORPORATION LAW We are subject to Section 203 of the Delaware General Corporation Law, which, subject to certain exceptions, prohibits a Delaware corporation from engaging in any business combination with any interested stockholder for a period of three years following the time that such stockholder became an interested stockholder, unless: - prior to such time, the board of directors of the corporation approved either the business combination or the transaction that resulted in the stockholder becoming an interested holder; 31 - upon consummation of the transaction that resulted in the stockholder becoming an interested stockholder, the interested stockholder owned at least 85% of the voting stock of the corporation outstanding at the time the transaction commenced, excluding for purposes of determining the number of shares outstanding those shares owned (a) by persons who are directors and also officers and (b) by employee stock plans in which employee participants do not have the right to determine confidentially whether shares held subject to the plan will be tendered in a tender or exchange offer; or - at or subsequent to such time, the business combination is approved by the board of directors and authorized at an annual or special meeting of stockholders, and not by written consent, by the affirmative vote of at least 66( 2)/(3)% of the outstanding voting stock which is not owned by the interested stockholder. In general, Section 203 defines "business combination" to include the following: - any merger or consolidation involving the corporation and the interested stockholder; - any sale, transfer, pledge or other disposition of 10% or more of the assets of the aggregate market value of the assets of the corporation involving the interested stockholder; - subject to certain exceptions, any transaction that results in the issuance or transfer by the corporation of any stock of the corporation to the interested stockholder; - any transaction involving the corporation that has the effect of increasing the proportionate share of the stock or any class or series of the corporation beneficially owned by the interested stockholder; or - the receipt by the interested stockholder of the benefit of any loans, advances, guarantees, pledges or other financial benefits provided by or through the corporation. In general, Section 203 defines "interested stockholder" as an entity or person beneficially owning 15% or more of the outstanding voting stock of the corporation and any entity or person affiliated with or controlling or controlled by such entity or person. CERTAIN TRANSACTIONS Our bylaws provide that we will indemnify our directors and officers, employees and other agents to the fullest extent permitted by Delaware law. We are also empowered under our bylaws to enter into indemnification contracts with our directors and officers and to purchase insurance on behalf of any person whom we are required or permitted to indemnify. In addition, our certificate of incorporation provides that the liability of the directors for monetary damages shall be eliminated to the fullest extent permissible under Delaware law. Pursuant to Delaware law, our directors shall not be liable for monetary damages for breach of the directors' fiduciary duty of care to us and our stockholders. However, this provision does not eliminate the duty of care, and in appropriate circumstances, equitable remedies such as injunctive or other forms of nonmonetary relief that will remain available under Delaware law. In addition, each director will continue to be subject to liability for (i) breach of the directors duty of loyalty to the corporation or its stockholders, (ii) acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (iii) violating Section 174 of the Delaware General Corporation Law, or (iv) any transaction from which the director derived an improper personal benefit. The provision also does not affect a director's responsibilities under any other law, such as the federal securities laws or state of federal environmental laws. TRANSFER AGENT AND REGISTRAR ChaseMellon Shareholder Services LLC is the transfer agent and registrar for our common stock. 32 CERTAIN UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS The following is a general discussion of certain anticipated U.S. federal income tax consequences to a holder with respect to the purchase, ownership and disposition of the notes or our common stock acquired upon conversion of a note as of the date hereof. This summary is generally limited to holders who will hold the notes and the shares of common stock into which the notes are convertible as "capital assets" within the meaning of Section 1221 of the Internal Revenue Code of 1986, as amended (the "Code") and does not deal with special situations including those that may apply to particular holders such as exempt organizations, holders subject to the U.S. federal alternative minimum tax, dealers in securities, commodities or foreign currencies, financial institutions, insurance companies, regulated investment companies, holders whose "functional currency" is not the U.S. dollar and persons who hold the notes or shares of common stock in connection with a "straddle," "hedging," "conversion" or other risk reduction transaction. This discussion does not address the tax consequences arising under any state, local or foreign law. The federal income tax considerations set forth below are based upon the Code, existing and proposed Treasury Regulations, court decisions, and Internal Revenue Service rulings now in effect, all of which are subject to change. We have not sought any ruling from the IRS with respect to statements made and conclusions reached in this discussion and there can be no assurance that the IRS will agree with such statements and conclusions. Prospective investors should particularly note that any such change could have retroactive application so as to result in federal income tax consequences different from those discussed below. As used herein, the term "U.S. holder" means a beneficial owner of a note (or our common stock acquired upon conversion of a note) that is for U.S. federal income tax purposes: - a citizen or resident of the United States; - a corporation or partnership created or organized in or under the laws of the United States or of any political subdivision thereof (other than a partnership that is not treated as a U.S. person under any applicable Treasury Regulations); - an estate the income of which is subject to U.S. federal income taxation regardless of its source; - a trust, if a court within the U.S. is able to exercise primary jurisdiction over its administration and one or more U.S. persons within the meaning of Section 7701(a)(30) of the Code have authority to control all of its substantial decisions, or if the trust has a valid election in effect under applicable U.S. Treasury regulations to be treated as a U.S. person; or - certain trusts in existence on August 20, 1996 and treated as U.S. persons under the Code and applicable Treasury Regulations that elect to continue to be treated as U.S. persons. As used herein, a "non-U.S. holder" means a holder that is not a U.S. holder. Prospective investors are urged to consult their tax advisors regarding the tax consequences, in their particular circumstances, of purchasing, holding and disposing of the notes or our common stock, including the tax consequences arising under any state, local or foreign laws. While the following does not purport to discuss all tax matters relating to the notes or the common stock acquired upon conversion of a note, the following are the material tax consequences of the notes and common stock acquired upon conversion of a note, subject to the qualifications set forth below. Based on currently applicable authorities, we are treating the notes as indebtedness for U.S. federal income tax purposes. However, since the notes have certain equity characteristics, it is possible that the IRS will contend that the notes should be treated as an equity interest in, rather than indebtedness of Inhale. Except as otherwise noted, the remainder of this discussion assumes that the notes constitute indebtedness for U.S. tax purposes. 33 U.S. HOLDERS STATED INTEREST The notes were not issued with more than a DE MINIMIS amount of original issue discount within the meaning of Section 1273(a) of the Code. As a result, interest paid on a note will be includable in the income of a U.S. holder as ordinary income at the time it accrues or is actually or constructively received in accordance with the holder's method of accounting for U.S. federal income tax purposes. CONVERSION OR REPURCHASE FOR COMMON STOCK A U.S. holder will not recognize income, gain or loss upon conversion of the notes solely into our common stock or a repurchase for common stock of a note pursuant to exercise of the repurchase right (except with respect to any amounts attributable to accrued interest on the notes, which will be treated as interest for federal income tax purposes), and except with respect to cash received in lieu of fractional shares, and with respect to market discount, as described below under "-Market Discount." The U.S. holder's basis in the common stock received on conversion or repurchase of a note for common stock pursuant to the repurchase right will be the same as the U.S. holder's adjusted tax basis in the notes at the time of conversion or repurchase (reduced by any basis allocable to a fractional share), and the holding period for the common stock received on conversion or repurchase will include the holding period of the notes that were converted or repurchased. Cash received in lieu of a fractional share of common stock upon conversion of the notes into common stock or upon a repurchase for common stock of a note pursuant to exercise of the repurchase right will be treated as a payment in exchange for the fractional share of common stock. Accordingly, the receipt of cash in lieu of a fractional share of common stock generally will result in capital gain or loss measured by the difference between the cash received for the fractional share and the U.S. holder's adjusted tax basis in the fractional share. DIVIDENDS ON COMMON STOCK Generally, distributions will be treated as a dividend, subject to tax as ordinary income, to the extent of our current or accumulated earnings or profits, then as a tax-free return of capital to the extent of such U.S. holder's adjusted tax basis in the common stock and thereafter as gain from the sale or exchange of such common stock. Additionally, a dividend distribution to a corporate U.S. holder may qualify for a dividends received deduction. DISPOSITION, REDEMPTION OR REPURCHASE FOR CASH Except as set forth above under "-Conversion or Repurchase for Common Stock," and below under "-Market Discount," U.S. holders generally will recognize capital gain or loss upon the sale, redemption, including a repurchase for cash pursuant to the repurchase right, or other taxable disposition of the notes or common stock in an amount equal to the difference between: - the U.S. holder's adjusted tax basis in the notes or common stock (as the case may be); and - the amount of cash and fair market value of any property received from such disposition (other than amounts attributable to accrued interest on the notes, which will be treated as interest for federal income tax purposes). A U.S. holder's adjusted tax basis in a note generally will equal the cost of the note to such U.S. holder, increased by market discount previously included in income by the U.S. holder and reduced by any amortized premium. Such gain or loss from the taxable disposition of the notes or common stock generally will be long-term capital gain or loss if the notes were held for more than one year at the time of the disposition and, in the case of an individual holder, will be taxed at a maximum federal rate of 20%. 34 Short term capital gains realized by individual U.S. holders are taxed at a maximum federal rate of 39.6%. Corporate U.S. holders are subject to a maximum federal regular income tax rate of 35% on all capital gains and ordinary income. The deductibility of capital losses is subject to limitations. MARKET DISCOUNT The resale of notes may be affected by the impact on a purchaser of the "market discount" provisions of the Code. For this purpose, the market discount on a note generally will be equal to the amount, if any, by which the stated redemption price at maturity of the note immediately after its acquisition exceeds the U.S. holder's adjusted tax basis in the note. Subject to a DE MINIMIS exception, these provisions generally require a U.S. holder who acquires a note at a market discount to treat as ordinary income any gain recognized on the disposition of the note to the extent of the "accrued market discount" on the note at the time of disposition, unless the U.S. holder elects to include accrued market discount in income currently. This election to include market discount in income currently, once made, applies to all market discount obligations acquired on or after the first taxable year to which the election applies and may not be revoked without the consent of the IRS. In general, market discount will be treated as accruing on a straight-line basis over the remaining term of the note at the time of acquisition, or, at the election of the U.S. holder, under a constant yield method. A U.S. holder who acquires a note at a market discount and who does not elect to include accrued market discount in income currently may be required to defer the deduction of a portion of the interest on any indebtedness incurred or maintained to purchase or carry the note until the note is disposed of in a taxable transaction. If a U.S. holder acquires a note with market discount and receives common stock upon conversion of the note, the amount of accrued market discount not previously included in income with respect to the converted note through the date of conversion will be treated as ordinary income and will increase the U.S. holder's basis in the note. AMORTIZABLE PREMIUM A U.S. holder who purchases a note at a premium over its stated principal amount, plus accrued interest, generally may elect to amortize such premium ("Section 171 premium") from the purchase date to the note's maturity date under a constant-yield method that reflects semiannual compounding based on the note's payment period. Amortizable premium, however, will not include any premium attributable to a note's conversion feature. The premium attributable to the conversion feature is the excess, if any, of the note's purchase price over what the note's fair market value would be if there were no conversion feature. Amortized Section 171 premium is treated as an offset to interest income on a note and not as a separate deduction. Bond premium on a note held by a U.S. holder that does not make the election to amortize will decrease the gain or increase the loss otherwise recognized upon disposition of the note. The election to amortize premium on a constant yield method, once made, applies to all debt obligations held or subsequently acquired by the electing U.S. holder on or after the first day of the first taxable year to which the election applies and may not be revoked without the consent of the IRS. ADJUSTMENT OF CONVERSION PRICE The conversion price of the notes is subject to adjustment under certain circumstances. Under Section 305 of the Code and the Treasury Regulations issued thereunder, adjustments or the failure to make such adjustments to the conversion price of the notes may result in a taxable constructive distribution to the U.S. holders of notes if, and to the extent that, certain adjustments or failure to make adjustments in the conversion price that may occur in limited circumstances (for example, an adjustment to reflect a taxable dividend to holders of our common stock) increase the proportionate interest of a U.S. holder in our assets or earnings and profits whether or not the U.S. holders ever convert the notes. Such constructive distribution will be treated as a dividend, resulting in ordinary income (and a possible dividends received deduction in the case of corporate holders) to the extent of 35 our current and accumulated earnings and profits, with any excess treated first as a tax-free return of capital which reduces the U.S. holder's tax basis in the notes to the extent thereof and thereafter as gain from the sale or exchange of the notes. Generally, a U.S. holder's tax basis in a note will be increased to the extent any such constructive distribution is treated as dividend. Moreover, if there is an adjustment (or a failure to make an adjustment) to the conversion price of the notes that increases the proportionate interest of the holders of outstanding common stock in our assets or earnings and profits, then such increase in the proportionate interest of the holders of the common stock generally will be treated as a constructive distribution to such holders, taxable as described above. As a result, U.S. holders of notes could have taxable income as a result of an event pursuant to which they receive no cash or property. DEDUCTIBILITY OF INTEREST Generally, under Section 279 of the Code, an interest deduction in excess of $5.0 million is not permitted with respect to certain "corporate acquisition indebtedness." Corporate acquisition indebtedness includes any indebtedness that is: - issued to provide consideration for the direct or indirect acquisition of stock or assets of another corporation; - subordinated; - convertible directly or indirectly into the stock of the issuing corporation; and - issued by a corporation that has a debt to equity ratio that exceeds 2 to 1. Our ability to deduct all of the interest payable on the notes will depend on the application of the foregoing tests to us. The availability of an interest deduction with respect to the notes was not determinative in our issuance of the notes pursuant to this offering. Under Section 163(l) of the Code, no deduction is permitted for interest paid or accrued on any indebtedness of a corporation that is "payable in equity" of the issuer or a related party. Debt is treated as debt payable in equity of the issuer if the debt is part of an arrangement designed to result in payment of the instrument with or by reference to the equity. Such arrangements could include debt instruments that are convertible at the holder's option if it is substantially certain that the option will be exercised. The legislative history indicates that it is not expected the provision will affect debt with a conversion feature where the conversion price is significantly higher than the market price of the stock on the date of the debt issuance. Accordingly, we do not believe that our interest deduction with respect to interest payments on the notes will be adversely affected by these rules. BACKUP WITHHOLDING AND INFORMATION REPORTING We or our designated paying agent will, where required, report to U.S. holders of notes or common stock and the IRS the amount of any interest paid on the notes (or dividends paid with respect to the common stock or other reportable payments) in each calendar year and the amount of tax, if any, withheld with respect to such payments. Under the backup withholding provisions of the Code and the applicable Treasury Regulations, a U.S. holder of notes or our common stock acquired upon the conversion of a note may be subject to backup withholding at the rate of 31% with respect to dividends or interest paid on, or the proceeds of a sale, exchange or redemption of, notes or common stock, unless: - such holder is a corporation or comes within certain other exempt categories and when required demonstrates this fact; or - provides a correct taxpayer identification number, certifies as to no loss of exemption from backup withholding and otherwise complies with applicable requirements of the backup withholding rules. 36 The amount of any backup withholding from a payment to a U.S. holder will be allowed as a credit against the U.S. holder's federal income tax liability and may entitle such holder to a refund, provided that the required information is furnished to the IRS. Treasury Regulations, generally effective January 1, 2001, subject to certain transition rules, modify the currently effective information withholding and backup withholding procedures and requirements. Prospective investors should consult their own tax advisors concerning the application of the new withholding regulations. NON-U.S. HOLDERS PAYMENTS OF INTEREST Generally, payments of interest on the notes to, or on behalf of, a non-U.S. holder will not be subject to U.S. federal withholding tax where such interest is not effectively connected with the conduct of a trade or business within the U.S. by such non-U.S. holder if: - such non-U.S. holder does not actually or constructively own 10% or more of the total combined voting power of all classes of our stock within the meaning of Code Section 871(h)(3); - such non-U.S. holder is not (a) a controlled foreign corporation for U.S. federal income tax purposes that is related to us through stock ownership or (b) a bank that received the note on an extension of credit made pursuant to a loan agreement entered into in the ordinary course of its trade or business as described in Code Section 881(c)(3)(A); and - the non-U.S. holder provides a statement signed under penalties of perjury that includes its name and address and certifies that it is not a U.S. person in compliance with applicable requirements of the Treasury Regulations or an exemption is otherwise established. If certain requirements are satisfied, the certification described above may be provided by a securities clearing organization, a bank, or other financial institution that holds customer's securities in the ordinary course of its trade or business. For purposes of this exception, the non-U.S. holder of notes would be deemed to own constructively the common stock into which it could be converted. If these requirements cannot be satisfied, a non-U.S. holder will be subject to U.S. federal withholding tax at a rate of 30% (or lower treaty rate, if applicable) on interest payments on the notes unless: - the interest is effectively connected with the conduct of a U.S. trade or business, in which case the interest will be subject to U.S. federal income tax on net income that applies to U.S. persons generally; or - an applicable income tax treaty provides for a lower rate of, or exemption from, withholding tax. CONVERSION OF NOTES A non-U.S. holder generally will not be subject to U.S. federal withholding tax on the conversion of a note into common stock. To the extent a non-U.S. holder receives cash in lieu of a fractional share of common stock upon conversion, such cash may give rise to gain that would be subject to the rules described below with respect to the sale or exchange of a note or common stock. See "-Sale or Exchange of Notes or Common Stock" below. ADJUSTMENT OF CONVERSION PRICE The conversion price of the notes is subject to adjustment in certain circumstances. Any such adjustment could, in certain circumstances, give rise to a deemed distribution to non-U.S. holders of the notes. See "U.S. Holders-Adjustment of Conversion Price" above. In such case, the deemed 37 distribution would be subject to the rules below regarding withholding of U.S. federal tax on dividends in respect of common stock. DISTRIBUTIONS ON COMMON STOCK Distributions on common stock will constitute a dividend for U.S. federal income tax purposes to the extent of our current or accumulated earnings and profits as determined under U.S. federal income tax principles. Dividends paid on common stock held by a non-U.S. holder will be subject to U.S. federal withholding tax at a rate of 30% (or lower treaty rate, if applicable), unless the dividend is effectively connected with the conduct of a U.S. trade or business by the non-U.S. holder and, if required by a tax treaty, is attributable to a permanent establishment maintained in the United States, in which case the dividend will be subject to U.S. federal income tax on net income that applies to U.S. persons generally (and, with respect to corporate holders under certain circumstances, the branch profits tax). A non-U.S. holder may be required to satisfy certain certification requirements in order to claim a reduction of or exemption from withholding under the foregoing rules. However, prior to January 1, 2001, for purposes of an applicable tax treaty, if a stockholder's address is outside the United States it will be assumed that such stockholder is a citizen or resident of that country absent the payor's knowledge to the contrary. SALE OR EXCHANGE OF NOTES OR COMMON STOCK In general, a non-U.S. holder will not be subject to a U.S. federal withholding tax on gain recognized upon the sale or other disposition (including a redemption) of a note or common stock received upon conversion thereof unless the gain is effectively connected with the conduct of a U.S. trade or business by the non-U.S. holder and, if required by a tax treaty, is attributable to a permanent establishment maintained in the United States, or unless the non-U.S. holder: - is a nonresident alien individual who is present in the United States for 183 or more days in the taxable year in which the gain is realized and certain other conditions are satisfied; or - is subject to tax pursuant to the provisions of U.S. tax law applicable to certain U.S. expatriates. However, if the Company were to become a United States real property holding corporation (a "USRPHC"), a non-U.S. holder might be subject to federal income tax withholding with respect to gain realized on the disposition of notes or shares of common stock. In that case, any withholding tax withheld pursuant to the rules applicable to dispositions of a "United States real property interest" would be creditable against such non-U.S. holder's U.S. federal income tax liability and might entitle such non-U.S. holder to a refund upon furnishing required information to the IRS. We do not believe that we are a USRPHC or will become a USRPHC in the future. U.S. ESTATE TAX Notes owned or treated as owned by an individual who is not a citizen or resident (as specifically defined for U.S. federal estate tax purposes) of the United States at the time of death (a "nonresident decedent") will not be includable in the nonresident decedent's gross estate for U.S. federal estate tax purposes as a result of such nonresident decedent's death, provided that, at the time of death, the nonresident decedent does not own, actually or constructively, 10% or more of the total combined voting power of all classes of our stock and payments with respect to such notes would not have been effectively connected with the conduct of a U.S. trade or business by the nonresident decedent. Common stock owned or treated as owned by a nonresident decedent will be includable in the nonresident decedent's gross estate for U.S. federal estate tax purposes as a result of the nonresident decedent's death. Subject to applicable treaty limitations, if any, a nonresident decedent's estate may be subject to U.S. federal estate tax on property includable in the estate for U.S. federal estate tax purposes. 38 BACKUP WITHHOLDING AND INFORMATION REPORTING A non-U.S. holder will generally not be subject to IRS reporting or backup withholding if the payor has received appropriate certification statements from or on behalf of the non-U.S. holder and provided that the payor does not have actual knowledge that the non-U.S. holder is a U.S. person. However, with respect to distributions on common stock, prior to January 1, 2001, if a stockholder's address is outside of the United States it will be assumed that such stockholder is a citizen or resident of that country absent the payor's knowledge to the contrary. The payment of the proceeds from the disposition of the notes or common stock to or through the U.S. office of any U.S. or foreign broker will be subject to IRS reporting and possibly backup withholding unless the owner certifies as to its non-U.S. status under penalties of perjury or otherwise establishes an exemption, provided that the broker does not have actual knowledge that the holder is a U.S. person or that the conditions of any other exemption are not, in fact, satisfied. The payment of the proceeds from the disposition of a note or common stock to or through a non-U.S. office of a non-U.S. broker that is not a U.S. related person will not be subject to IRS or backup withholding. For this purpose, a "U.S. related person" is: - a "controlled foreign corporation" for U.S. federal income tax purposes; or - a non-U.S. person 50% or more of whose gross income from all sources for the three-year period ending with the close of its taxable year preceding the payment (or for such part of the period that the broker has been in existence) is derived from activities that are effectively connected with the conduct of a U.S. trade or business. In the case of the payment of proceeds from the disposition of notes or common stock to or through a non-U.S. office of a broker that is a U.S. related person, the applicable Treasury Regulations require IRS reporting on the payment unless the broker has documentary evidence in its files that the owner is a non-U.S. holder and the broker has no knowledge to the contrary. Backup withholding will not apply to payments made through foreign offices of a broker that is a U.S. person or a U.S. related person (absent actual knowledge that the payee is a U.S. person). Any amounts withheld under the backup withholding rates from a payment to a non-U.S. holder will be allowed as a credit against such holder's U.S. federal income tax liability, if any, or will otherwise be refundable, provided that the requisite procedures are followed. Non-U.S. holders of the notes or common stock should consult their own tax advisors regarding their qualification for exemption from backup withholding and the procedure for obtaining such an exemption, if applicable. The IRS has issued new withholding regulations generally effective January 1, 2001. The proposed regulations provide that information reporting, but not backup withholding, may apply to a payment made outside the United States of the proceeds of a sale of a note through an office outside the United States of a broker that is a foreign partnership if one or more of its partners are "U.S. persons," as defined in the Treasury Regulations, who in the aggregate hold more than 50% of the income or capital interest in the partnership or such foreign partnership is engaged in a U.S. trade or business, unless the broker has documentary evidence in its records that the holder is a non-U.S. person and does not have actual knowledge that the holder is a U.S. person, or the holder otherwise establishes an exemption. Non-U.S. holders should consult their own tax advisors with respect to the future impact of these new withholding regulations. The preceding discussion of certain U.S. federal income tax consequences is for general information only and is not tax advice. Accordingly, you should consult your own tax adviser as to particular tax consequences to you of purchasing, holding and disposing of the notes and our common stock, including the applicability and effect of any state, local or foreign tax laws, and of any proposed changes in applicable laws. 39 SELLING SECURITY HOLDERS The notes were originally issued by us and sold by the initial purchasers in a transaction exempt from the registration requirements of the Securities Act to persons reasonably believed by the initial purchasers to be qualified institutional buyers. Selling holders, including their transferees, pledgees or donees or their successors, may from time to time offer and sell pursuant to this prospectus any or all of the notes and common stock into which the notes are convertible. The following table sets forth information, as of January 11, 2001, with respect to the selling holders and the principal amounts of notes beneficially owned by each selling holder that may be offered under this prospectus. The information is based on information provided by or on behalf of the selling holders. The selling holders may offer all, some or none of the notes or common stock into which the notes are convertible. Because the selling holders may offer all or some portion of the notes or the common stock, no estimate can be given as to the amount of the notes or the common stock that will be held by the selling holders upon termination of any sales. In addition, the selling holders identified below may have sold, transferred or otherwise disposed of all or a portion of their notes since the date on which they provided the information regarding their notes in transactions exempt from the registration requirements of the Securities Act.

- ------------------------ Additional information regarding selling holders will be provided by amendment or supplement to this Registration Statement. With the exception of Merrill Lynch Pierce Fenner & Smith Inc. and Deutsche Bank Securities Inc., none of the selling holders nor any of their affiliates, officers, directors or principal equity holders has held any position or office or has had any material relationship with us within the past three years, although the selling holders may hold additional securities of Inhale. Merrill Lynch Pierce Fenner & Smith Inc. and Deutsche Bank Securities Inc. were initial purchasers of the notes. The selling holders purchased the notes in private transactions on or after October 27, 2000. All of the notes were "restricted securities" under the Securities Act prior to this registration. Information concerning the selling holders may change from time to time and any changed information will be set forth in supplements to this prospectus if and when necessary. In addition, the conversion rate and therefore, the number of shares of common stock issuable upon conversion of the notes, is subject to adjustment under certain circumstances. Accordingly, the aggregate principal amount of notes and the number of shares of common stock into which the notes are convertible may increase or decrease. 43 PLAN OF DISTRIBUTION The sellingholders and their successors, including their transferees, pledgees or donees or their successors, may sell the notes and the common stock into which the notes are convertible directly to purchasers or through underwriters, broker-dealers or agents, who may receive compensation in the form of discounts, concessions or commissions from the selling holders or the purchasers. These discounts, concessions or commissions as to any particular underwriter, broker-dealer or agent may be in excess of those customary in the types of transactions involved. The notes and the common stock into which the notes are convertible may be sold in one or more transactions at fixed prices, at prevailing market prices at the time of sale, at prices related to the prevailing market prices, at varying prices determined at the time of sale, or at negotiated prices. These sales may be effected in transactions, which may involve crosses or block transactions: - on any national securities exchange or U.S. inter-dealer system of a registered national securities association on which the notes or the common stock may be listed or quoted at the time of sale; - in the over-the-counter market; - in transactions otherwise than on these exchanges or systems or in the over-the-counter market; - through the writing of options, whether the options are listed on an options exchange or otherwise; or - through the settlement of short sales. In connection with the sale of the notes and the common stock into which the notes are convertible or otherwise, the selling holders may enter into hedging transactions with broker-dealers or other financial institutions, which may in turn engage in short sales of the notes or the common stock into which the notes are convertible in the course of hedging the positions they assume. The selling holders may also sell the notes or the common stock into which the notes are convertible short and deliver these securities to close out their short positions, or loan or pledge the notes or the common stock into which the notes are convertible to broker-dealers that in turn may sell these securities. The aggregate proceeds to the selling holders from the sale of the notes or common stock into which the notes are convertible offered by them will be the purchase price of the notes or common stock less discounts and commissions, if any. Each of the selling holders reserves the right to accept and, together with their agents from time to time, to reject, in whole or in part, any proposed purchase of notes or common stock to be made directly or through agents. We will not receive any of the proceeds from this offering. Our outstanding common stock is listed for trading on the Nasdaq National Market. We do not intend to list the notes for trading on any national securities exchange or on the Nasdaq National Market and can give no assurance about the development of any trading market for the notes. The notes are currently eligible for trading on the PORTAL market of the Nasdaq Stock Market. In order to comply with the securities laws of some states, if applicable, the notes and common stock into which the notes are convertible may be sold in these jurisdictions only through registered or licensed brokers or dealers. In addition, in some states the notes and common stock into which the notes are convertible may not be sold unless they have been registered or qualified for sale or an exemption from registration or qualification requirements is available and is complied with. The selling holders and any underwriters, broker-dealers or agents that participate in the sale of the notes and common stock into which the notes are convertible may be "underwriters" within the meaning of Section 2(11) of the Securities Act. Any discounts, commissions, concessions or profit they earn on any resale of the shares may be underwriting discounts and commissions under the Securities Act. Selling holders who are "underwriters" within the meaning of Section 2(11) of the Securities Act 44 will be subject to the prospectus delivery requirements of the Securities Act. The selling holders have acknowledged that they understand their obligations to comply with the provisions of the Exchange Act and the rules thereunder relating to stock manipulation, particularly Regulation M. In addition, any securities covered by this prospectus that qualify for sale pursuant to Rule 144 or Rule 144A of the Securities Act may be sold under Rule 144 or Rule 144A rather than pursuant to this prospectus. A selling holder may not sell any notes or common stock described in this prospectus and may not transfer, devise or gift these securities by other means not described in this prospectus. To the extent required, the specific notes or common stock to be sold, the names of the selling holders, the respective purchase prices and public offering prices, the names of any agent, dealer or underwriter, and any applicable commissions or discounts with respect to a particular offer will be set forth in an accompanying prospectus supplement or, if appropriate, a post-effective amendment to the registration statement of which this prospectus is a part. We entered into a registration rights agreement for the benefit of holders of the notes to register their notes and common stock under applicable federal and state securities laws under specific circumstances and at specific times. The registration rights agreement provides for cross-indemnification of the selling holders and us and their and our respective directors, officers and controlling persons against specific liabilities in connection with the offer and sale of the notes and the common stock, including liabilities under the Securities Act. We will pay substantially all of the expenses incurred by the selling holders incident to the offering and sale of the notes and the common stock.

ITEM 15. INDEMNIFICATION OF OFFICERS AND DIRECTORS. Under Section 145 of the Delaware General Corporation Law, Inhale has broad powers to indemnify our directors and officers against liabilities they may incur in such capacities, including liabilities under the Securities Act of 1933, as amended (the "Securities Act"). Inhale's certificate of incorporation, as amended provides for the elimination of liability for monetary damages for breach of the directors' fiduciary duty of care to Inhale and its stockholders. These provisions do not eliminate the directors' duty of care and, in appropriate circumstances, equitable remedies such an injunctive or other forms of non-monetary relief will remain available under Delaware law. In addition, each director will continue to be subject to liability for breach of the director's duty of loyalty to Inhale, for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, for any transaction from which the director derived an improper personal benefit and for violating Section 174 of the Delaware General Corporation Law. The provision does not affect a director's responsibilities under any other laws, such as the federal securities laws or state or federal environmental laws. Inhale has entered into agreements with its directors and executive officers that require Inhale to indemnify such persons against expenses, judgments, fines, settlements and other amounts actually and reasonably incurred (including expenses of a derivative action) in connection with any proceeding, whether actual or threatened, to which any such person may be made a party by reason of the fact that such person is or was a director or officer of Inhale or any of its affiliated enterprises, provided such person acted in good faith and in a manner such person reasonably believed to be in or not opposed to the best interests of Inhale and, with respect to any criminal proceeding, had no reasonable cause to believe his or her conduct was unlawful. The indemnification agreements also set forth certain procedures that will apply in the event of a claim for indemnification thereunder. II-1 ITEM 16. EXHIBITS

(16) Incorporated by reference to the indicated exhibit in Inhale's Current Report on Form 8-K, filed with the SEC on January 11, 2001. (17) Filed herewith. II-4 ITEM 17. UNDERTAKINGS The undersigned registrant hereby undertakes: (1) To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement: (i) To include any prospectus required by Section 10(a)(3) of The Securities Act of 1933. (ii) To reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than 20 percent change in the maximum aggregate offering price set forth in the "Calculation of Registration Fee" table in the effective registration statement. (iii) To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement; PROVIDED, HOWEVER, that paragraphs (1)(i) and (1)(ii) do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in periodic reports filed with or furnished to the Commission by Inhale pursuant to Section 13 or 15(d) of the Securities Exchange Act of 1934 that are incorporated by reference in the registration statement. (2) That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial BONA FIDE offering thereof. (3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering. (4) The undersigned Inhale hereby undertakes that, for purposes of determining any liability under the Securities Act of 1933, each filing of Inhale's annual report pursuant to Section 13(a) or 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan's annual report pursuant to Section 15(d) of the Exchange Act) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein and the offering of such securities at that time shall be deemed to be the initial BONA FIDE offering thereof. (5) Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of Inhale pursuant to provisions described in Item 15, or otherwise, Inhale has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by Inhale of expenses incurred or paid by a director, officer or controlling person of Inhale in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, Inhale will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue. II-5 SIGNATURES Pursuant to the requirements of the Securities Act of 1933, the registrant certifies that it has reasonable grounds to believe that it meets all of the requirements for filing on Form S-3 and has duly caused this registration statement to be signed on its behalf by the undersigned, thereunto duly authorized, in the City of San Carlos, County of San Mateo, State of California on January 11, 2001.

Ladies and Gentlemen:

         Inhale Therapeutic Systems, Inc., a Delaware corporation (the
"Company"), confirms its agreement with Merrill Lynch, Pierce, Fenner & Smith
Incorporated ("Merrill Lynch") and each of the other Initial Purchasers named in
SCHEDULE A hereto (collectively, the "Initial Purchasers", which term shall also
include any initial purchaser substituted as hereinafter provided in Section 8
hereof), for whom Merrill Lynch and Deutsche Bank Securities Inc. are acting as
representatives (in such capacity, the "Representatives"), with respect to the
issue and sale by the Company and the purchase by the Initial Purchasers, acting
severally and not jointly, of the respective principal amounts set forth in said
SCHEDULE I of $200,000,000 aggregate principal amount of the Company's 3 1/2%
Convertible Subordinated Notes due 2007 (the "Firm Notes"), and with respect to
the grant by the Company to the Initial Purchasers, acting severally and not
jointly, of the option described in Section 2(b) hereof (the "Option") to
purchase all or any part of an additional $50,000,000 principal amount of the
Company's 3 1/2% Convertible Subordinated Notes due 2007 to cover
over-allotments, if any (the "Optional Notes" and, together with the Firm Notes,
the "Notes").

         The Notes will be convertible into fully paid, nonassessable shares of
common stock of the Company, par value $0.0001 per share (the "Common Stock"),
on the terms, and subject to the conditions, set forth in the Indenture. As used
herein, "Conversion Shares" means the shares of Common Stock into which the
Notes are convertible. The Notes will be issued pursuant to an


                                       1


Indenture (the "Indenture") to be dated as of the First Delivery Date (as
defined in Section 2(a)), between the Company and Chase Manhattan Bank and Trust
Company, National Association, as Trustee (the "Trustee").

         The Notes will be offered and sold without being registered under the
Securities Act of 1933, as amended (the "Securities Act"), in reliance on
exemptions therefrom. The Company has prepared and delivered to each Initial
Purchaser copies of a preliminary offering memorandum dated October 9, 2000 (the
"Preliminary Offering Memorandum") and has prepared and will deliver to each
Initial Purchaser, on the date hereof or the next succeeding day, copies of a
final offering memorandum dated October 11, 2000 (the "Final Offering
Memorandum"), each for use by such Initial Purchaser in connection with its
solicitation of purchases of, or offering of, the Notes. "Offering Memorandum"
means, with respect to any date or time referred to in this Agreement, the most
recent offering memorandum (whether the Preliminary Offering Memorandum or the
Final Offering Memorandum, or any amendment or supplement to either such
document), including exhibits thereto and any documents incorporated therein by
reference, which has been prepared and delivered by the Company to the Initial
Purchasers in connection with their solicitation of purchases of, or offering
of, the Notes.

         Holders of the Notes (including the Initial Purchasers and their direct
and indirect transferees) will be entitled to the benefits of a Resale
Registration Rights Agreement, dated the First Delivery Date, between the
Company and the Initial Purchasers (the "Registration Rights Agreement"),
pursuant to which the Company will agree to file with the Securities and
Exchange Commission (the "Commission") a shelf registration statement pursuant
to Rule 415 under the Securities Act (the "Registration Statement") covering the
resale of the Notes and the Conversion Shares, and to use its best efforts to
cause the Registration Statement to be declared effective.

         This Agreement, the Indenture, the Notes and the Registration Rights
Agreement are referred to herein collectively as the "Operative Documents".

         Capitalized terms used herein without definition have the respective
meanings specified in the Offering Memorandum.

         1. REPRESENTATIONS, WARRANTIES AND AGREEMENTS OF THE COMPANY. The
Company represents and warrants to each Initial Purchaser as of the date hereof
and as of each Delivery Date (as defined in Section 2(b)) and agrees with each
Initial Purchaser, as follows:

         (a) Each of the Preliminary Offering Memorandum and the Offering
Memorandum, did not as of its respective date, and the Offering Memorandum will
not as of a Delivery Date (as defined in Section 2(b)), contain any untrue
statement of a material fact or omit to state a material fact necessary in order
to make the statements therein, in the light of the circumstances under which
they were made, not misleading; PROVIDED that the Company makes no
representation or warranty as to information contained in or omitted from the
Preliminary Offering Memorandum or the Offering Memorandum in reliance upon and
in conformity with written information furnished to the Company by or on the
behalf of any Initial Purchaser through the Representatives specifically for
inclusion therein.

                                       2


         (b) Assuming the accuracy of the representations and warranties of the
Initial Purchasers contained in Section 6 and their compliance with the
agreements set forth therein, it is not necessary, in connection with the
issuance and sale of the Notes to the Initial Purchasers and the offer, resale
and delivery of the Notes by the Initial Purchasers in the manner contemplated
by this Agreement, the Indenture, the Registration Rights Agreement and the
Offering Memorandum, to register the Notes or the Conversion Shares under the

         (c) The Company has been duly incorporated and is validly existing as a
corporation in good standing under the laws of the State of Delaware, is duly
qualified to do business and is in good standing as a foreign corporation in
each jurisdiction in which its ownership or lease of property or the conduct of
its businesses requires such qualification (except for where the failure to be

management, business, properties, financial condition, results of operations or
prospects of the Company, whether or not arising in the ordinary course of
business (a "Material Adverse Effect")), and has all power and authority
necessary to own or hold its properties and to conduct the businesses in which

the preemptive or other similar rights of any securityholder of the Company; the
capital stock of the Company conforms to the description thereof contained in

the instruments defining the same; the Conversion Shares, which are authorized
on the date hereof, have been duly and validly authorized and reserved for
issuance upon conversion of the Notes by all necessary corporate action and are
free of preemptive rights; all Conversion Shares, when so issued and delivered
upon such conversion in accordance with the terms of the Indenture, will be duly
and validly authorized and issued, fully paid and nonassessable and free and
clear of all liens, encumbrances, equities or claims; and the issuance of such
Conversion Shares upon such conversion will not be subject to the preemptive or
other similar rights of any securityholder of the Company.

         (e) The execution, delivery and performance of the Operative Documents
by the Company and the issuance of the Notes and the Conversion Shares and the
consummation of the transactions contemplated hereby and thereby will not (x)
conflict with or result in a breach or violation of any of the terms or
provisions of, or constitute a default under, any indenture, mortgage, deed of
trust, loan agreement or other agreement or instrument to which the Company is a
party or by which the Company is bound or to which any of the properties or
assets of the Company is subject, (y) result in any violation of the provisions
of the certificate of incorporation or bylaws of the Company or (z) result in
any violation of any statute or any order, rule or regulation of any court or
governmental agency or body having jurisdiction over the Company or any of its
properties or assets; and except (i) with respect to the transactions

Securities Act, the Trust Indenture Act and the rules and regulations
promulgated thereunder and (ii) as


                                       3


required by the state securities or "blue sky" laws, no consent, approval,
authorization or order of, or filing or registration with, any such court or
governmental agency or body is required for the execution, delivery and
performance of the Operative Documents by the Company, and the consummation of
the transactions contemplated hereby and thereby.

         (f) The Company has all necessary corporate right, power and authority
to execute and deliver this Agreement and perform its obligations hereunder; and

authorized, executed and delivered by the Company.

         (g) The Company has all necessary corporate right, power and authority
to execute and deliver the Indenture and perform its obligations thereunder; the
Indenture has been duly authorized by the Company, and upon the effectiveness of
the Registration Statement, will be qualified under the Trust Indenture Act; on
the First Delivery Date, the Indenture will have been duly executed and
delivered by the Company and, assuming due authorization, execution and delivery
of the Indenture by the Trustee, will constitute a legally valid and binding
agreement of the Company enforceable against the Company in accordance with its
terms, except as the enforceability thereof may be limited by bankruptcy,
insolvency, fraudulent transfer, reorganization, moratorium and other similar
laws relating to or affecting creditors' rights generally, subject to general
principles of equity and to limitations on availability of equitable relief,
including specific performance (whether considered in a proceeding in equity or
at law) and an implied covenant of good faith and fair dealing; and the

it will be a legally valid and binding agreement of the Company enforceable
against the Company in accordance with its terms, except as the enforceability
thereof may be limited by bankruptcy, insolvency, fraudulent transfer,
reorganization, moratorium and other similar laws relating to or affecting
creditors' rights generally, subject to general principles of equity and to
limitations on availability of equitable relief, including specific performance
(whether considered in a proceeding in equity or at law) and an implied covenant
of good faith and fair dealing, and except with respect to the rights of
indemnification and contribution thereunder, where enforcement thereof may be
limited by federal or state securities laws or the policies underlying such
laws; and the Registration Rights Agreement conforms in all material respects to
the description thereof contained in the Offering Memorandum and will be in

         (t) Except as disclosed in the Offering Memorandum, there are no legal
or governmental proceedings pending to which the Company is a party or of which
any property or asset of the Company is the subject which, if determined
adversely to the Company might have a Material Adverse Effect, or which might
reasonably be expected to materially and adversely affect the consummation of
the transactions contemplated by this Agreement or the performance by the
Company of its obligations hereunder; to the Company's knowledge, no such
proceedings are threatened or contemplated by governmental authorities or,
except as set forth or contemplated in the Offering Memorandum, threatened by
others; and the aggregate of all pending legal or governmental proceedings to
which the Company is a party or of which any of its property or assets is the
subject (other than the Company's patent applications currently pending before
the U.S. Patent and Trademark Office or before any foreign governmental
authority that administers the registration of patents), which are not described
in the Offering Memorandum, including ordinary routine litigation incidental to
the business, could not reasonably be expected to result in a Material Adverse
Effect.

         (u) No event has occurred nor has any circumstance arisen which, had
the Notes been issued on such Delivery Date, would constitute a default or an
Event of Default (as such term is defined in the Indenture).

         (v) The Company is not (i) in violation of its certificate of
incorporation or bylaws, (ii) in default, and no event has occurred which, with
notice or lapse of time or both, would constitute such a default, in the due
performance or observance of any term, covenant or condition contained in any
indenture, mortgage, deed of trust, loan agreement or other agreement or
instrument to which it is a party or by which it is bound or to which any of its
properties or assets is subject or (iii) in violation of any law, ordinance,
governmental rule, regulation or court decree to which it or its properties or
assets may be subject or has failed to obtain any license, permit, certificate,
franchise or other governmental authorization or permit necessary to the
ownership of its properties or to the conduct of its business, except to the
extent that any such default, event or violation described in the foregoing
clauses (i), (ii) and (iii) would not have a Material Adverse Effect.

         (w) The Company is in compliance in all material respects with all
presently applicable provisions of the Employee Retirement Income Security Act
of 1974, as amended, including the regulations and published interpretations
thereunder ("ERISA"); no "reportable event" (as defined in ERISA) has occurred
with respect to any "pension plan" (as defined in ERISA) for which the Company
would have any liability; the Company has not incurred and does not expect to
incur liability under (i) Title IV of ERISA with respect to termination of, or
withdrawal from, any "pension plan" or (ii) Sections 412 or 4971 of the Internal
Revenue Code of 1986, as amended, including the regulations and published
interpretations thereunder (the "Code"); and each "pension plan" for which the
Company would have any liability that is intended to be qualified under Section
401(a) of the Code is so qualified in all material respects and nothing has
occurred, whether by action or by failure to act, which would cause the loss of
such qualification.

         (x) The Company is subject to the reporting requirements of Section 13
or Section 15(d) of the Exchange Act. The Company has timely and properly filed
with the Commission all reports and other documents required to have been filed

refinement, transportation, handling or treatment of toxic wastes, medical
wastes, hazardous wastes or hazardous substances by the Company (or, to the
knowledge of the Company, any of its predecessors in interest) at, upon or from
any of the property now or previously owned or leased by the Company in
violation of any applicable law, ordinance, rule, regulation, order, judgment,
decree or permit or which would require remedial action under any applicable
law, ordinance, rule, regulation, order, judgment, decree or permit, except for
any violation or remedial action which would not have, or could not be
reasonably likely to have, singularly or in the aggregate with all such
violations and remedial actions a Material Adverse Effect; there has been no
material spill, discharge, leak, emission, injection, escape, dumping or release
of any kind onto such property or into the environment surrounding such property
of any toxic wastes, medical wastes, solid wastes, hazardous wastes or hazardous
substances due to or caused by the Company or with respect to which the Company
has knowledge, except for any such spill, discharge, leak, emission, injection,
escape, dumping or release which would not have or would not be reasonably
likely to have, singularly or in the aggregate with all such spills, discharges,
leaks, emissions, injections, escapes, dumpings and releases, a Material Adverse
Effect; and the terms "hazardous wastes", "toxic wastes", "hazardous substances"
and "medical wastes" shall have the meanings specified in any applicable local,
state, federal and foreign laws or regulations with respect to environmental
protection.

prospectus included in a registration statement on Form S-1 that has not been so
described.

         (cc) Since the date as of which information is given in the Offering
Memorandum through the date hereof, the Company has not (i) issued or granted

ordinary course of business, (iii) entered into any material transaction not in

                                       9

         (jj) None of the Company or any of its Affiliates (as defined in Rule
501(b) of Regulation D under the Securities Act ("Regulation D")) (other than
the Initial Purchasers, about

                                       10


which no representation is made by the Company), has, directly or through an
agent, engaged or will engage in any form of general solicitation or general
advertising in connection with the offering of the Notes (as those terms are
used in Regulation D) under the Securities Act or in any manner involving a
public offering within the meaning of Section 4(2) of the Securities Act; the
Company has not entered into any contractual arrangement with respect to the
distribution of the Notes except for this Agreement and the Company will not
enter into any such arrangement.

         (kk) None of the Company or any of its affiliates (other than the

         (ll) The Company has not taken, directly or indirectly, any action

         2. PURCHASE, SALE AND DELIVERY OF NOTES.

         (a) Subject to the terms and conditions and in reliance upon the
representations and warranties herein set forth, the Company agrees to sell to
each Initial Purchaser, and each Initial Purchaser agrees, severally and not
jointly, to purchase from the Company, at a purchase price of 97.00% of the
principal amount thereof (the "purchase price") the principal amount of Firm
Notes set forth opposite such Initial Purchaser's name in SCHEDULE I hereto (or
such number increased as set forth in Section 8).

         Delivery of and payment for the Firm Notes shall be made at the office
of Brown & Wood LLP, One World Trade Center, New York, New York 10048, at 10:00
a.m. (New York City time) on October 17, 2000, or such later date as the Initial
Purchasers shall designate, which date and time may be postponed by agreement
between the Initial Purchasers and the Company or as provided in Section 8 (such
date and time of delivery and payment for the Firm Notes being herein called the
"First Delivery Date"). Delivery of the Firm Notes shall be made to the Initial
Purchasers against payment of the purchase price by the Initial Purchasers.
Payment for the Firm Notes shall be effected either by wire transfer of
immediately available funds to an account with a bank in The City of New York,
the account number and the ABA number for such bank to be provided by the
Company to the Initial Purchasers at least two business days in advance of the
First Delivery Date, or by such other manner of payment as may be agreed by the
Company and the Initial Purchasers. It is understood that each Initial Purchaser
has authorized the Representatives, for its account, to accept delivery of,
issue a receipt for, and make payment of the purchase price for, the Firm Notes
that it has agreed to purchase. Merrill Lynch, individually and not as
representative of the Initial Purchasers, may (but shall not be obligated to)
make payment of the purchase price for the Firm Notes to be purchased by any
Initial Purchaser whose funds have not been received by the First Delivery Date
but such payment shall not relieve such Initial Purchaser from its obligations
hereunder.

                                       11


         (b) Subject to the terms and conditions and in reliance upon the
representations and warranties herein set forth, the Company hereby grants the
Option to the Initial Purchasers to purchase, severally and not jointly, the
Optional Notes at the same price as the Initial Purchasers shall pay for the
Firm Notes and the principal amount of the Optional Notes to be sold to each
Initial Purchaser shall be that principal amount which bears the same ratio to
the aggregate principal amount of Optional Notes being purchased as the
principal amount of Firm Notes set forth opposite the name of such Initial
Purchaser in SCHEDULE I hereto (or such number increased as set forth in Section
8). The Option may be exercised only to cover over-allotments in the sale of the
Firm Notes by the Initial Purchasers. The Option may be exercised once in whole
or in part at any time not more than 30 days subsequent to the date of this
Agreement upon notice in writing or by facsimile by the Representatives to the
Company setting forth the amount (which shall be an integral multiple of $1,000)
of Optional Notes as to which the Initial Purchasers are exercising the Option.

         The date for the delivery of and payment for the Optional Notes, being
herein referred to as an "Optional Delivery Date", which may be the First
Delivery Date (the First Delivery Date and the Optional Delivery Date, if any,
being sometimes referred to as a "Delivery Date"), shall be determined by the
Initial Purchasers but shall not be later than five full business days after
written notice of election to purchase Optional Notes is given. Delivery of the
Optional Notes shall be made to the Initial Purchasers against payment of the
purchase price by the Initial Purchasers. Payment for the Optional Notes shall
be effected either by wire transfer of immediately available funds to an account
with a bank in The City of New York, the account number and the ABA number for
such bank to be provided by the Company to the Initial Purchasers at least two
business days in advance of the Optional Delivery Date, or by such other manner
of payment as may be agreed by the Company and the Initial Purchasers. It is
understood that each Initial Purchaser has authorized the Representatives, for
its account, to accept delivery of, issue a receipt for, and make payment of the
purchase price for, the Optional Notes that it has agreed to purchase. Merrill
Lynch, individually and not as representative of the Initial Purchasers, may
(but shall not be obligated to) make payment of the purchase price for the
Optional Notes to be purchased by any Initial Purchaser whose funds have not
been received by the Delivery Date but such payment shall not relieve such
Initial Purchaser from its obligations hereunder.

         (c) The Company will deliver against payment of the purchase price the
Notes initially sold to qualified institutional buyers ("QIBs"), as defined in
Rule 144A under the Securities Act ("Rule 144A") in the form of one or more
permanent global certificates (the "Global Notes"), registered in the name of
Cede & Co., as nominee for The Depository Trust Company ("DTC"). Beneficial
interests in the Notes initially sold to QIBs will be shown on, and transfers
thereof will be effected only through, records maintained in book-entry form by
DTC and its participants.

         The Global Notes will be made available, at the request of the Initial
Purchasers, for checking at least 24 hours prior to such Delivery Date. The
Certificated Notes will be made available, at the request of the Initial
Purchasers, for checking at least 48 hours prior to such Delivery Date.

                                       12


         (d) Time shall be of the essence, and delivery at the time and place
specified pursuant to this Agreement is a further condition of the obligations
of the Initial Purchasers hereunder.

         3. FURTHER AGREEMENTS OF THE COMPANY. The Company further agrees with
each Initial Purchaser as follows:

         (a) The Company will advise the Initial Purchasers promptly of any
proposal to amend or supplement the Offering Memorandum and not to effect any
such amendment or supplement without the consent of the Initial Purchasers
and/or Brown & Wood LLP, counsel to the Initial Purchasers. Neither the consent
of the Initial Purchasers, nor the Initial Purchaser's delivery of any such
amendment or supplement, shall constitute a waiver of any of the conditions set
forth in Section 5. The Company will immediately notify each Initial Purchaser,
and confirm such notice in writing, of (i) any filing made by the Company of
information relating to the offering of the Notes by the Company with any
securities exchange or any other regulatory body in the United States or any
other jurisdiction, and (ii) prior to the completion of the placement of the
Notes by the Initial Purchasers as evidenced by a notice in writing from the
Initial Purchasers to the Company, any material changes in or affecting the
condition, financial or otherwise, or the earnings, business affairs or business
prospects of the Company which (x) make any statement in the Offering Memorandum
false or misleading or (y) are not disclosed in the Offering Memorandum. In such
event or if during such time any event shall occur or condition exist as a
result of which it is necessary to amend or supplement the Offering Memorandum
in order that the Offering Memorandum will not include an untrue statement of a
material fact or omit to state a material fact necessary in order to make the
statements therein, in the light of the circumstances existing at the time it is
delivered to a purchaser, not misleading, to promptly notify the Initial
Purchasers and/or Brown & Wood LLP, counsel to the Initial Purchasers, and
prepare, subject to the first sentence of this Section 3(a), such amendment or
supplement as may be necessary to correct such untrue statement or omission.

         (b) The Company will furnish to the Initial Purchasers and to Brown &
Wood LLP, counsel to the Initial Purchasers, copies of the Preliminary Offering
Memorandum and the Offering Memorandum (and all amendments and supplements
thereto) in each case as soon as available and in such quantities as the Initial
Purchasers reasonably request for internal use and for distribution to
prospective purchasers; and to furnish to the Initial Purchasers on the date
hereof four copies of the Offering Memorandum signed by duly authorized officers
of the Company, one of which will include the independent auditors' reports
therein manually signed by such independent auditors. The Company will pay the
expenses of printing and distributing to the Initial Purchasers all such
documents.

         (c) The Company will use its reasonable efforts to take such action as
the Initial Purchasers may reasonably request from time to time, to qualify the
Notes and the Conversion Shares for offering and sale under the securities laws
of such jurisdictions as the Initial Purchasers may request and to comply with
such laws so as to permit the continuance of sales and dealings therein in such
jurisdictions in the United States for as long as may be necessary to complete
the resale of the Notes; PROVIDED that in connection therewith, the Company
shall not be required to qualify as a foreign corporation or otherwise subject
itself to taxation in any jurisdiction in which it is not otherwise so qualified
or subject.

                                       13


         (d) The Company will apply the proceeds from the sale of the Notes as
set forth under "Use of Proceeds" in the Offering Memorandum.

         (e) During a period of 90 days from the date of the Offering
Memorandum, the Company will not, and will cause its directors and officers not
to, without the prior written consent of Merrill Lynch, (i) directly or
indirectly, offer, pledge, sell, contract to sell, sell any option or contract
to purchase, purchase any option or contract to sell, grant any option right or
warrant to purchase or otherwise transfer or dispose of any Common Stock or any
securities convertible into or exercisable or exchangeable for Common Stock
(collectively, the "Restricted Securities") or file any registration statement
under the Securities Act with respect to any Restricted Securities, or (ii)
enter into any swap or any other agreement or any transaction (other than the
Operative Documents) that transfers, in whole or in part, directly or
indirectly, the economic consequence of ownership of any Restricted Securities,
whether any such swap or transaction described in clause (i) or (ii) above is to
be settled by delivery of Restricted Securities, in cash or otherwise. The
foregoing sentence shall not apply to Authorized Grants, the issuance of shares
pursuant to Authorized Warrants, the Old Conversion Shares, the Conversion
Shares or the sale of up to $125 million in the aggregate of the Company's
Common Stock (as measured on the date of such sales(s)) only (x) in a private
placement or (y) in connection with the Company's acquisition of companies. The
Company further agrees not to permit to become effective under the Securities
Act during a period of 90 days from the date of the Offering Memorandum a
registration statement, other than a registration statement on Form S-4 relating
to the acquisition of the entity or of the outstanding securities of the entity
discussed under "Recent Events" in the Offering Memorandum, covering any shares
of the Company's Common Stock sold pursuant to a transaction described in
clauses (x) and (y) above. The Company further agrees to cause each officer and
director of the Company to furnish to the Initial Purchasers, prior to the First
Delivery Date, a letter or letters, in form and substance satisfactory to
counsel to the Initial Purchasers, pursuant to which each such person shall
agree not to enter into any transaction described in clause (i) or (ii) of the
first sentence of this paragraph; PROVIDED, HOWEVER, that such restrictions
shall not apply to the sale of up to 500,000 shares of Common Stock in the
aggregate by all such officers and directors.

         (f) The Company agrees that it will not, and will cause its Affiliates
(as defined in Rule 501(b) of Regulation D) not to, directly or indirectly,
solicit any offer to buy, sell or make any offer or sale of, or otherwise
negotiate in respect of, securities of the Company of any class if, as a result
of the doctrine of "integration" referred to in Rule 502 under the Securities
Act, such offer or sale would render invalid (for the purpose of (i) the sale of
the Notes by the Company to the Initial Purchasers, (ii) the resale of the Notes
by the Initial Purchasers to subsequent purchasers or (iii) the resale of the
Notes or Conversion Shares by such subsequent purchasers to others) the
exemption from the registration requirements of the Securities Act provided by
Section 4(2) thereof or by Rule 144A thereunder or otherwise. Notwithstanding
the foregoing, no stockholder of the Company that does not control, is not
controlled by or is not under common control with, an officer or director of the
Company shall be deemed to be an Affiliate for purposes of this paragraph.

         (g) For so long as any of the Notes are "restricted securities" within
the meaning of Rule 144(a)(3) under the Securities Act, the Company will provide
to any holder of the Notes or to any prospective purchaser of the Notes
designated by any holder, upon request of such holder

                                       14


or prospective purchaser, information required to be provided by Rule 144A(d)(4)
of the Securities Act if, at the time of such request, the Company is not
subject to the reporting requirements under Section 13 or 15(d) of the Exchange
Act.

         (h) Until the expiration of two years after the original issuance of
the Notes, the Company will not, and will cause its Affiliates (as defined in
Rule 501(b) of Regulation D) not to, resell any Notes or Conversion Shares which
are "restricted securities" (as such term is defined under Rule 144(a)(3) under
the Securities Act), whether as beneficial owner or otherwise (except as agent
acting as a securities broker on behalf of and for the account of customers in
the ordinary course of business in unsolicited broker's transactions).
Notwithstanding the foregoing, no stockholder of the Company that does not
control, is not controlled by or is not under common control with, an officer or
director of the Company shall be deemed to be an Affiliate for purposes of this
paragraph.

         (i) Each of the Notes will bear, to the extent applicable, the legend
contained in "Notice to Investors" in the Offering Memorandum for the time
period and upon the other terms stated therein, except after the Notes are
resold pursuant to a registration statement effective under the Securities Act.

         (j) The Company will take such steps as shall be necessary to ensure
that it shall not become an "investment company" within the meaning of such term
under the Investment Company Act, and the rules and regulations of the
Commission thereunder.

         (k) None of the Company or any of its affiliates will take, directly or
indirectly, any action which is designed to stabilize or manipulate, or which
constitutes or which might reasonably be expected to cause or result in
stabilization or manipulation, of the price of any security of the Company in
connection with the offering of the Notes.

         (l) The Company will execute and deliver the Registration Rights
Agreement in form and substance satisfactory to the Initial Purchasers.

         (m) The Company will use its best efforts to assist the Initial
Purchasers in arranging to cause the Notes to be accepted to trade in the PORTAL
market ("PORTAL") of the National Association of Securities Dealers, Inc.
("NASD").

         (n) The Company will use its best efforts to cause the Notes to be
accepted for clearance and settlement through the facilities of DTC.

         (o) The Company will use its best efforts to have the Conversion Shares
approved by the Nasdaq National Market ("Nasdaq") for inclusion prior to the
effectiveness of the Registration Statement.

         4. EXPENSES. The Company agrees to pay:

         (a) the costs incident to the authorization, issuance, sale and
delivery of the Notes, and any taxes payable in that connection;

                                       15

         (a) No Initial Purchaser shall have discovered and disclosed to the
Company prior to or on such Delivery Date that the Offering Memorandum or any
amendment or supplement thereto contains any untrue statement of a fact which,
in the opinion of counsel to the Initial Purchasers, is material or omits to
state any fact which is material and necessary to make the statements therein,
in the light of the circumstances under which they were made, not misleading.

                                       16


         (b) All corporate proceedings and other legal matters incident to the
authorization, form and validity of the Operative Documents and the Offering

and information that they may reasonably request to enable them to pass upon

         (c) Cooley Godward LLP shall have furnished to the Initial Purchasers
their written opinion, as counsel to the Company, addressed to the Initial
Purchasers and dated such Delivery Date, in form and substance satisfactory to
the Initial Purchasers, to the effect that:

                  (i) The Company has been duly organized and is validly
         existing as a corporation in good standing under the laws of the State
         of Delaware, and, based solely on certificates of public officials, is
         duly qualified to do business and is in good standing as a foreign
         corporation in each jurisdiction in which its ownership or lease of
         property or the conduct of its business requires such qualification,
         except where the failure to be so qualified would not have a material
         adverse effect on the Company, whether or not arising in the ordinary
         course of business, and has all corporate power and authority necessary
         to own or hold its properties and conduct the businesses in which it is
         engaged, as described in the Offering Memorandum; and, to the knowledge
         of such counsel, the Company has no subsidiaries;

                  (ii) the Conversion Shares, which are authorized on the date
         hereof, have been duly and validly authorized and reserved for issuance
         upon conversion of the Notes by all necessary corporate action and are
         free of preemptive rights; all Conversion Shares, when so issued and
         delivered upon such conversion in accordance with the terms of the
         Indenture, will be duly and validly authorized and issued, fully paid
         and nonassessable and free and clear of all liens, encumbrances,
         equities or claims imposed by or arising from actions of the Company;

                  (iii) The statements in the Offering Memorandum under the
         captions "Description of the Notes" and "Description of Capital Stock",
         insofar as they purport to summarize the provisions of the Indenture,
         the Registration Rights Agreement, the Notes and the Common Stock
         (including the Conversion Shares) are accurate and complete in all
         material respects to the extent required if such statements were
         contained in a registration statement on Form S-3 under the Securities
         Act;

                  (iv) There is no restriction upon the voting or transfer of,
         any shares of Common Stock pursuant to the Company's certificate of
         incorporation or bylaws;

                  (v) To the knowledge of such counsel and other than as set
         forth in the Offering Memorandum, there are no legal or governmental
         proceedings pending to which the Company is a party or of which any
         property or asset of the Company is the subject which, if determined
         adversely to the Company might have a material adverse effect on the
         Company or which might reasonably be expected to materially and
         adversely affect the consummation of the transactions contemplated by
         this Agreement or the performance by the Company of its obligations
         hereunder; to the actual knowledge of such counsel, no such proceedings
         are overtly threatened or contemplated by governmental authorities or,
         except as set forth or contemplated in the Offering Memorandum, overtly
         threatened by others; and, to the actual knowledge of

                                       17


         such counsel, the aggregate of all pending legal or governmental
         proceedings to which the Company is a party or of which any of its
         property or assets is the subject (other than the Company's patent
         applications currently pending before the U.S. Patent and Trademark
         Office or before any foreign governmental authority that administers
         the registration of patents) which are not described in the Offering
         Memorandum, including ordinary routine litigation incidental to the
         business, could not reasonably be expected to result in a material
         adverse effect on the Company.

                  (vi) The execution, delivery and performance of this
         Agreement, the Indenture and the Registration Rights Agreement and the
         issuance of the Notes and the Conversion Shares and the consummation of
         the transactions contemplated hereby and thereby do not result in any
         violation of the provisions of the certificate of incorporation or
         bylaws of the Company or any statute or any order, rule or regulation
         known to such counsel of any court or governmental agency or body
         having jurisdiction over the Company or any of its properties or
         assets; and, except as may be required by the securities or "blue sky"
         laws of any state of the United States in connection with the sale of
         the Notes, no consent, approval, authorization or order of, or filing
         or registration with, any such court or governmental agency or body is
         required for the execution, delivery and performance of this Agreement
         and the Indenture by the Company and the issuance of the Notes and the
         Conversion Shares and the consummation of the transactions contemplated
         hereby and thereby;

                  (vii) No registration of the Notes or the Conversion Shares
         under the Securities Act, and no qualification of the Indenture or an
         indenture under the Trust Indenture Act, is required in connection with
         the offer, sale and delivery of the Notes or in connection with the
         conversion of the Notes into Conversion Shares, in each case, in the
         manner contemplated by the Offering Memorandum, this Agreement and the
         Indenture;

                  (viii) The statements in the Offering Memorandum under the
         caption "Certain United States Federal Income Tax Considerations",
         insofar as they purport to constitute summaries of matters of United
         States federal income tax law and regulations or legal conclusions with
         respect thereto, constitute accurate summaries of the matters described
         therein in all material respects to the extent required if such
         statements were contained in a registration statement on Form S-3 under
         the Securities Act;

                  (ix) The Company is not an "investment company" within the
         meaning of the Investment Company Act of 1940, as amended;

                  (x) The Company has all necessary corporate right, power and
         authority to execute and deliver each of the Operative Documents to
         which it is a party and to perform its obligations thereunder and to
         issue, sell and deliver the Notes and the Conversion Shares to the
         Initial Purchasers;

                                       18


                  (xi) This Agreement has been duly authorized, executed and
         delivered by the Company;

                  (xii) The Indenture has been duly authorized, executed and
         delivered by the Company and, assuming due authorization, execution and
         delivery thereof by the Trustee, constitutes a legally valid and
         binding agreement of the Company enforceable against the Company in
         accordance with its terms except as the enforceability thereof may be
         limited by bankruptcy, insolvency, fraudulent transfer, reorganization,
         moratorium and other similar laws relating to or affecting creditors'
         rights generally, subject to general principles of equity and to
         limitations on availability of equitable relief, including specific
         performance (regardless of whether such enforceability is considered in
         a proceeding in equity or at law) or by an implied covenant of good
         faith and fair dealing;

                  (xiii) The Registration Rights Agreement has been duly
         authorized, executed and delivered by the Company and, assuming due
         authorization, execution and delivery thereof by the Initial
         Purchasers, constitutes a valid and legally binding agreement of the
         Company enforceable against the Company in accordance with its terms
         except as rights to indemnity contained therein may be limited by
         applicable law and except as the enforceability thereof may be limited
         by bankruptcy, insolvency, fraudulent transfer, reorganization,
         moratorium and other similar laws relating to or affecting creditors'
         rights generally, subject to general principles of equity and to
         limitations on availability of equitable relief, including specific
         performance (regardless of whether such enforceability is considered in
         a proceeding in equity or at law), by an implied covenant of good faith
         and fair dealing; and

                  (xiv) The Notes have been duly authorized by the Company and
         when executed, issued and authenticated in accordance with terms of the
         Indenture and delivered to and paid for by the Initial Purchasers, will
         constitute legally valid and binding obligations of the Company,
         entitled to the benefits of the Indenture and enforceable against the
         Company in accordance with their terms except as the enforceability
         thereof may be limited by bankruptcy, insolvency, fraudulent transfer,
         reorganization, moratorium and other similar laws relating to or
         affecting creditors' rights generally, subject to general principles of
         equity and to limitations on availability of equitable relief,
         including specific performance (regardless of whether such
         enforceability is considered in a proceeding in equity or at law) or by
         an implied covenant of good faith and fair dealing.

         In rendering such opinion, such counsel may state that its opinion is
limited to matters governed by the federal laws of the United States of America,
the laws of the State of New York and the Delaware General Corporation Law and
may state that it is relying, in respect of matters of New York law, upon Brown
& Wood LLP, and in respect of matters of fact, upon certificates of officers of
the Company, PROVIDED that such counsel shall state that it believes that the
Initial Purchasers and it are justified in relying upon such certificates. Such
counsel shall also have furnished to the Initial Purchasers a written statement,
addressed to the Initial Purchasers and dated such Delivery Date, in form and
substance satisfactory to the Initial Purchasers, to the effect that during the
course of preparing the Offering Memorandum, such counsel participated in
conferences with officers and other representatives of the Company, the
Company's independent public accountants, the Initial Purchasers and their
counsel, at which the contents of

                                       19


the Offering Memorandum were discussed, and while such counsel has not
independently verified and is not passing upon the accuracy, completeness or
fairness of the statements made in the Offering Memorandum except as explicitly
set forth above, no facts have come to the attention of such counsel which lead
it to believe that the Offering Memorandum (other than the financial statements,
financial and statistical data and supporting schedules as to which such counsel
shall make no statement), as of its date or as of such Delivery Date, contained
or contains any untrue statement of a material fact or omitted or omits to state
a material fact necessary in order to make the statements therein, in light of
the circumstances under which they were made, not misleading.

         (d) Stephen L. Hurst, Esq., General Counsel and Secretary of the
Company, shall have furnished to the Initial Purchasers his written opinion,
addressed to the Initial Purchasers and dated such Delivery Date, in form and
substance satisfactory to the Initial Purchasers, to the effect that:

             (i) The authorized, issued and outstanding capital stock of the
         Company, as of June 30, 2000, is as set forth in the Offering
         Memorandum under the column entitled "Actual" under the caption
         "Capitalization", and all of the issued and outstanding shares of
         capital stock of the Company have been duly and validly authorized and
         issued, are fully paid and nonassessable;

             (ii) Except as disclosed in the Offering Memorandum, there are no
         preemptive or other rights to subscribe for or to purchase from the
         Company, or any restriction upon the voting or transfer of, any shares
         of Common Stock pursuant to any agreement or other instrument to which
         the Company is a party known to such counsel; the issuance of the
         Conversion Shares, upon conversion of the Notes in accordance with the
         terms of the Indenture, will not be subject to the preemptive or other
         similar rights of any securityholder of the Company and

             (iii) The execution, delivery and performance of this Agreement,
         the Indenture and the Registration Rights Agreement and the issuance of
         the Notes and the Conversion Shares and the consummation of the
         transactions contemplated hereby and thereby do not result in a breach
         or violation of any of the terms or provisions of, or constitute a
         default under, any indenture, mortgage, deed of trust, loan agreement
         or other agreement or instrument known to such counsel to which the
         Company is a party or by which the Company is bound or to which any of
         the property or assets of the Company is subject.

         Such counsel shall also have furnished to the Initial Purchasers a
written statement, addressed to the Initial Purchasers and dated such Delivery
Date, in form and substance satisfactory to the Initial Purchasers, to the
effect that he has no reason to believe that the statements under the captions
"Risk Factors--Our patents may not protect our products and our products may
infringe on third-party patent rights" and "Patents and Proprietary Rights" in
the Offering Memorandum, as of its date or as of such Delivery Date, contained
or contains any untrue statement of a material fact or omitted or omits to state
a material fact necessary in order to make the statements therein, in light of
the circumstances under which they were made, not misleading.

                                       20


         (e) Brown & Wood LLP, shall have furnished to the Initial Purchasers
their written opinion, as counsel to the Initial Purchasers, addressed to the
Initial Purchasers and dated such Delivery Date, in form and substance
satisfactory to the Initial Purchasers.

         (f) With respect to the letter of Ernst & Young LLP delivered to the
Initial Purchasers concurrently with the execution of this Agreement (the
"initial letter"), the Company shall have furnished to the Initial Purchasers a

Purchasers and dated such Delivery Date (i) confirming that they are independent
accountants within the meaning of the Securities Act and are in compliance with
the applicable requirements relating to the qualification of accountants under
Rule 2-01 of Regulation S-X of the Commission, (ii) stating, as of the date of
the bring-down letter (or, with respect to matters involving changes or
developments since the respective dates as of which specified financial
information is given in the Offering Memorandum, as of a date not more than five
days prior to the date of the bring-down letter), the conclusions and findings
of such firm with respect to the financial information and other matters covered
by the initial letter and (iii) confirming in all material respects the
conclusions and findings set forth in the initial letter.

         (g) The Company shall have furnished to the Initial Purchasers on such
Delivery Date a certificate, dated such Delivery Date and delivered on behalf of
the Company by one of its co-chief executive officers and its chief financial
officer, in form and substance satisfactory to the Initial Purchasers, to the
effect that:

             (i) The representations, warranties and agreements of the Company
         in Section 1 are true and correct as of the date given and as of such
         Delivery Date; and the Company has complied in all material respects
         with all its agreements contained herein to be performed prior to or on
         such Delivery Date;

             (ii) (A) The Company has not sustained since the date of the latest
         audited financial statements included in the Offering Memorandum any
         loss or interference with its business from fire, explosion, flood or
         other calamity, whether or not covered by insurance, or from any labor
         dispute or court or governmental action, order or decree, except (x) as
         set forth or contemplated in the Offering Memorandum and (y) for
         operating losses incurred in the ordinary course of business, or (B)
         since such date there has not been any change in the capital stock or
         long-term debt of the Company (except for issuances of shares of Common
         Stock upon conversion of Old Debentures or exercise of outstanding
         options or warrants described in the Offering Memorandum or pursuant to
         Authorized Grants, Authorized Warrants or the Dressler Issuance), or
         any change, or any development involving a prospective change, in or
         affecting the general affairs, management, financial position,
         stockholders' equity or results of operations of the Company, except as
         set forth or contemplated in the Offering Memorandum; and

             (iii) Such officer has carefully examined the Offering Memorandum
         and, in such officer's opinion (A) the Offering Memorandum, as of its
         date, did not include any untrue statement of a material fact and did
         not omit to state any material fact necessary to make the statements
         therein, in the light of the circumstances under which they were made,
         not misleading, and (B) since the date of the Offering Memorandum, no
         event has

                                       21


         occurred which should have been set forth in a supplement or
         amendment to the Offering Memorandum.

         (h) The Indenture shall have been duly executed and delivered by the
Company and the Trustee and the Notes shall have been duly executed and
delivered by the Company and duly authenticated by the Trustee.

         (i) The Company and the Initial Purchasers shall have executed and
delivered the Registration Rights Agreement (in form and substance satisfactory
to the Initial Purchasers) and the Registration Rights Agreement shall be in
full force and effect.

         (j) The NASD shall have accepted the Notes for trading on PORTAL.

         (k) (i) The Company shall not have sustained since the date of the
latest audited financial statements included in the Offering Memorandum any loss
or interference with its business from fire, explosion, flood or other calamity,
whether or not covered by insurance, or from any labor dispute or court or
governmental action, order or decree, except (A) as set forth or contemplated in
the Offering Memorandum and (B) for operating losses incurred in the ordinary
course of business, or (ii) since such date there shall not have been any change
in the capital stock or long-term debt of the Company (except for issuances of
shares of Common Stock upon conversion of Old Debentures or exercise of
outstanding options or warrants described in the Offering Memorandum or pursuant
to Authorized Grants, Authorized Warrants or the Dressler Issuance), or any
change, or any development involving a prospective change, in or affecting the
general affairs, management, financial position, stockholders' equity or results
of operations of the Company, except as set forth or contemplated in the
Offering Memorandum, the effect of which, in any such case described in clause
(i) or (ii), is, in the reasonable judgment of the Initial Purchasers, so
material and adverse as to make it impracticable or inadvisable to proceed with
the sale or the delivery of the Notes being delivered on such Delivery Date on
the terms and in the manner contemplated in the Offering Memorandum.

         (l) The Company shall have furnished to the Initial Purchasers such
further information, certificates and documents as the Initial Purchasers may
reasonably request to evidence compliance with the conditions set forth in this
Section 5.

         All opinions, letters, evidence and certificates mentioned above or
elsewhere in this Agreement shall be deemed to be in compliance with the
provisions hereof only if they are in form and substance satisfactory to counsel
to the Initial Purchasers.

         If any condition specified in this Section 5 shall not have been
fulfilled when and as required to be fulfilled, this Agreement may be terminated
by the Representatives by notice to the Company at any time at or prior to the
First Delivery Date, and such termination shall be without liability of any
party to any other party except as provided in Section 4 and except that
Sections 1 and 7 shall survive any such termination and remain in full force and
effect.

         6. REPRESENTATIONS, WARRANTIES AND AGREEMENTS OF INITIAL PURCHASERS.
Each Initial Purchaser, severally and not jointly, represents and warrants that
such Initial Purchaser is a QIB. Each Initial Purchaser, severally and not
jointly, agrees with the Company that:

                                       22


         (a) The Notes and the Conversion Shares have not been and will not be
registered under the Securities Act in connection with the initial offering of
the Notes.

         (b) Such Initial Purchaser is a QIB;

         (c) Such Initial Purchaser will not offer or sell the Notes in the
United States by means of any form of general solicitation or general
advertising within the meaning of Rule 502(c) of Regulation D, including (i) any
advertisement, article, notice or other communication published in any
newspaper, magazine or similar medium or broadcast over television or radio, or
(ii) any seminar or meeting whose attendees have been invited by any general
solicitation or general advertising in the United States; and

         (d) Such Initial Purchaser has not offered or sold, and will not offer
or sell, any Notes in the United States except to persons whom it reasonably
believes to be QIBs.

         7. INDEMNIFICATION AND CONTRIBUTION.

         (a) The Company shall indemnify and hold harmless each Initial
Purchaser, its officers and employees and each person, if any, who controls any
Initial Purchaser within the meaning of Section 15 of the Securities Act or
Section 20 of the Exchange Act from and against any loss, claim, damage or
liability, joint or several, or any action in respect thereof (including, but
not limited to, any loss, claim, damage, liability or action relating to
purchases and sales of the Notes), to which that Initial Purchaser, officer,
employee or controlling person may become subject:

             (i) insofar as such loss, claim, damage, liability or action arises
         out of, or is based upon: (A) any untrue statement or alleged untrue
         statement of a material fact contained in (I) any Preliminary Offering
         Memorandum or the Offering Memorandum, or in any amendment or
         supplement thereto, or (II) any blue sky application or other document
         prepared or executed by the Company (or based upon any written
         information furnished by the Company) filed in any jurisdiction
         specifically for the purpose of qualifying any or all of the Notes
         under the securities laws of any state or other jurisdiction (such
         application, document or information being hereinafter called a "Blue
         Sky Application"), or (B) the omission or alleged omission to state
         therein any material fact necessary to make the statements therein not
         misleading; or

             (ii) to the extent of the aggregate amount paid in settlement of
         any litigation, or any investigation or proceeding by any governmental
         agency or body, commenced or threatened, or of any claim whatsoever
         based upon any such untrue statement or omission, or any such alleged
         untrue statement or omission; provided that (subject to Section 7(c))
         any such settlement is effected with the written consent of the
         Company,

and shall reimburse each Initial Purchaser and each such officer, employee and
controlling person promptly upon demand for any and all expense whatsoever, as
incurred (including the fees and disbursements of counsel chosen by Merrill
Lynch, except as reimbursement of such fees may be limited by Section 7(c)),
reasonably incurred by that Initial Purchaser, officer, employee or controlling
person in connection with investigating or defending or preparing to defend
against any such loss, claim, damage, liability or action as such expenses are
incurred;

                                       23


PROVIDED, HOWEVER, that the Company shall not be liable in any such case to the
extent that any such loss, claim, damage, liability or action arises out of, or
is based upon, any untrue statement or alleged untrue statement or omission or
alleged omission made in any Preliminary Offering Memorandum or the Offering
Memorandum, or in any such amendment or supplement, or in any Blue Sky
Application in reliance upon and in conformity with the written information
furnished to the Company by or on behalf of any Initial Purchaser specifically
for inclusion therein and described in Section 7(e); PROVIDED, FURTHER, that as
to any Preliminary Offering Memorandum, this indemnity agreement shall not inure
to the benefit of any Initial Purchaser, its officers or employees or any person
controlling that Initial Purchaser on account of any loss, claim, damage,
liability or action arising from the sale of Notes to any person by that Initial
Purchaser if that Initial Purchaser failed to send or give a copy of the
Offering Memorandum, as the same may be amended or supplemented, to that person,
and the untrue statement or alleged untrue statement of a material fact or
omission or alleged omission to state a material fact in such Preliminary
Offering Memorandum was corrected in the Offering Memorandum, unless such
failure resulted from non-compliance by the Company with Section 3(b). The
foregoing indemnity agreement is in addition to any liability which the Company
may otherwise have to any Initial Purchaser or to any officer, employee or
controlling person of that Initial Purchaser.

         (b) Each Initial Purchaser, severally and not jointly, shall indemnify
and hold harmless, the Company, its officers and directors, and each person, if
any, who controls the Company within the meaning of Section 15 of the Securities
Act or Section 20 of the Exchange Act from and against any loss, claim, damage
or liability, joint or several, or any action in respect thereof, to which the
Company or any such director, officer or controlling person may become subject,
insofar as such loss, claim, damage, liability or action arises out of, or is
based upon:

             (i) any untrue statement or alleged untrue statement of a material
         fact contained in any Preliminary Offering Memorandum or the Offering
         Memorandum or in any amendment or supplement thereto, or in any Blue
         Sky Application, or

             (ii) the omission or alleged omission to state therein any material
         fact necessary to make the statements therein not misleading,

but in each case only to the extent that such untrue statement or alleged untrue
statement or omission or alleged omission was made in reliance upon and in
conformity with the written information furnished to the Company by or on behalf
of that Initial Purchaser specifically for inclusion therein and described in
Section 7(e), and shall reimburse the Company and any such director, officer or
controlling person promptly upon demand for any legal or other expenses
reasonably incurred by the Company or any such director, officer or controlling
person in connection with investigating or defending or preparing to defend
against any such loss, claim, damage, liability or action as such expenses are
incurred. The foregoing indemnity agreement is in addition to any liability
which any Initial Purchaser may otherwise have to the Company or any such
director, officer or controlling person.

         (c) Promptly after receipt by an indemnified party under this Section 7
of notice of any claim or the commencement of any action, the indemnified party
shall, if a claim in respect thereof is to be made against the indemnifying
party under this Section 7, notify the

                                       24


indemnifying party in writing of the claim or the commencement of that action;
PROVIDED, HOWEVER, that the failure to notify the indemnifying party shall not
relieve it from any liability which it may have under this Section 7 except to
the extent it has been materially prejudiced by such failure and, PROVIDED,
FURTHER, that the failure to notify the indemnifying party shall not relieve it
from any liability which it may have to an indemnified party otherwise than
under this Section 7. If any such claim or action shall be brought against an
indemnified party, and it shall notify the indemnifying party thereof, the
indemnifying party shall be entitled to participate therein and, to the extent
that it wishes, jointly with any other similarly notified indemnifying party, to
assume the defense thereof with counsel satisfactory to the indemnified party.
After notice from the indemnifying party to the indemnified party of its
election to assume the defense of such claim or action, the indemnifying party
shall not be liable to the indemnified party under this Section 7 for any legal
or other expenses subsequently incurred by the indemnified party in connection
with the defense thereof other than reasonable costs of investigation; PROVIDED,
HOWEVER, that the Initial Purchasers shall have the right to employ counsel to
represent jointly the Initial Purchasers and their respective officers,
employees and controlling persons who may be subject to liability arising out of
any claim in respect of which indemnity may be sought by the Initial Purchasers
against the Company under this Section 7, if the Initial Purchasers shall have
reasonably concluded that there may be one or more legal defenses available to
the Initial Purchasers and their respective officers, employees and controlling
persons that are different from or additional to those available to the Company
and its officers, employees and controlling persons, the fees and expenses of a
single separate counsel shall be paid by the Company. No indemnifying party
shall:

             (i) without the prior written consent of the indemnified parties
         (which consent shall not be unreasonably withheld) settle or compromise
         or consent to the entry of any judgment with respect to any pending or
         threatened claim, action, suit or proceeding in respect of which
         indemnification or contribution may be sought hereunder (whether or not
         the indemnified parties are actual or potential parties to such claim
         or action) unless such settlement, compromise or consent (1) includes
         an unconditional release of each indemnified party from all liability
         arising out of such claim, action, suit or proceeding and (2) does not
         include a statement as to or an admission of fault, culpability or a
         failure to act by or on behalf of any indemnified party, or

             (ii) be liable for any settlement of any such action effected
         without its written consent (which consent shall not be unreasonably
         withheld) but if settled with its written consent or if there be a
         final judgment of the plaintiff in any such action, the indemnifying
         party agrees to indemnify and hold harmless any indemnified party from
         and against any loss of liability by reason of such settlement or
         judgment.

         (d) If the indemnification provided for in this Section 7 shall for any
reason be unavailable or insufficient to hold harmless an indemnified party
under Section 7(a) or 7(b) in respect of any loss, claim, damage or liability,
or any action in respect thereof, referred to therein, each indemnifying party
shall, in lieu of indemnifying such indemnified party, contribute to the amount
paid or payable by such indemnified party as a result of such loss, claim,
damage or liability, or action in respect thereof:

                                       25


             (i) in such proportion as shall be appropriate to reflect the
         relative benefits received by the Company on the one hand and the
         Initial Purchasers on the other from the offering of the Notes, or

             (ii) if the allocation provided by clause 7(d)(i) is not permitted
         by applicable law, in such proportion as is appropriate to reflect not
         only the relative benefits referred to in clause 7(d)(i) but also the
         relative fault of the Company on the one hand and the Initial
         Purchasers on the other with respect to the statements or omissions or
         alleged statements or alleged omissions that resulted in such loss,
         claim, damage or liability (or action in respect thereof), as well as
         any other relevant equitable considerations.

         The relative benefits received by the Company on the one hand and the
Initial Purchasers on the other with respect to such offering shall be deemed to
be in the same proportion as the total net proceeds from the offering of the
Notes purchased under this Agreement (before deducting expenses) received by the
Company on the one hand, and the total discounts and commissions received by the
Initial Purchasers with respect to the Notes purchased under this Agreement, on
the other hand, bear to the total gross proceeds from the offering of the Notes
under this Agreement, in each case as set forth in the table on the cover page
of the Offering Memorandum.

         The relative fault shall be determined by reference to whether the
untrue or alleged untrue statement of a material fact or omission or alleged
omission to state a material fact relates to information supplied by the Company
or the Initial Purchasers, the intent of the parties and their relative
knowledge, access to information and opportunity to correct or prevent such
statement or omission.

         The Company and the Initial Purchasers agree that it would not be just
and equitable if the amount of contributions pursuant to this Section 7(d) were
to be determined by PRO RATA allocation (even if the Initial Purchasers were
treated as one entity for such purpose) or by any other method of allocation
which does not take into account the equitable considerations referred to
herein. The amount paid or payable by an indemnified party as a result of the
loss, claim, damage or liability, or action in respect thereof, referred to
above in this Section 7(d) shall be deemed to include, for purposes of this
Section 7(d), any legal or other expenses reasonably incurred by such
indemnified party in connection with investigating, preparing or defending any
such litigation, investigation or proceeding by any governmental agency or body,
or commenced or threatened action or claim.

         Notwithstanding the provisions of this Section 7(d), no Initial
Purchaser shall be required to contribute any amount in excess of the amount by
which the total price at which the Notes resold by it in the initial placement
of such Notes were offered to investors exceeds the amount of any damages which
such Initial Purchaser has otherwise been required to pay by reason of such
untrue or alleged untrue statement or omission or alleged omission.

         No person guilty of fraudulent misrepresentation (within the meaning of
Section 11(f) of the Securities Act) shall be entitled to contribution from any
person who was not guilty of such fraudulent misrepresentation.

                                       26


         For purposes of this Section 7(d), each person, if any, who controls an
Initial Purchaser within the meaning of Section 15 of the Securities Act or
Section 20 of the Exchange Act shall have the same rights to contribution as
such Initial Purchaser, and each person, if any, who controls the Company within
the meaning of Section 15 of the Securities Act or Section 20 of the Exchange
Act shall have the same rights to contribution as the Company. The Initial
Purchasers' obligations to contribute as provided in this Section 7(d) are
several in proportion to their respective purchase obligations and not joint.

         (e) The Initial Purchasers severally confirm that the statements (i)
with respect to the offering of the Notes set forth in the third sentence of the
ninth paragraph on the cover page of the Offering Memorandum; (ii) in the third
sentence of the second paragraph under the heading "Plan of Distribution" in the
Offering Memorandum; (iii) in the fourth paragraph under "Plan of Distribution";
(iv) in the first paragraph under the heading "Plan of Distribution--Commissions
and Discounts" in the Offering Memorandum; (v) in the paragraph under the
heading "Plan of Distribution--Notes Are Not Being Registered" in the Offering
Memorandum; (vi) in the third and fourth sentences of the first paragraph under
the heading "Plan of Distribution--New Issue of Notes" in the Offering
Memorandum; and (vii) in the first and third sentences of the first paragraph
under the heading "Plan of Distribution--Price Stabilization and Short
Positions" in the Offering Memorandum are correct and constitute the only
information furnished in writing to the Company by or on behalf of the Initial
Purchasers specifically for inclusion in the Offering Memorandum.

         8. DEFAULTING INITIAL PURCHASERS.

         If, on any Delivery Date, any Initial Purchaser defaults in the
performance of its obligations under this Agreement, the remaining
non-defaulting Initial Purchasers shall be obligated to purchase the aggregate
principal amount of Notes which the defaulting Initial Purchaser agreed but
failed to purchase on such Delivery Date in the respective proportions which the
total aggregate principal amount of Notes set opposite the name of each
remaining non-defaulting Initial Purchaser in Schedule 1 hereto bears to the
total aggregate principal amount of Notes set opposite the names of all the
remaining non-defaulting Initial Purchasers in Schedule 1 hereto; PROVIDED,
HOWEVER, that the remaining non-defaulting Initial Purchasers shall not be
obligated to purchase any Notes on such Delivery Date if the total aggregate
principal amount of Notes which the defaulting Initial Purchasers agreed but
failed to purchase on such date exceeds 9.09% of the total aggregate principal
amount at maturity of Notes to be purchased on such Delivery Date, and any
remaining non-defaulting Initial Purchaser shall not be obligated to purchase
more than 110% of the aggregate principal amount at maturity of Notes which it
agreed to purchase on such Delivery Date pursuant to the terms of Section 2. If
the foregoing maximums are exceeded, the remaining non-defaulting Initial
Purchasers, or those other purchasers satisfactory to the Initial Purchasers who
so agree, shall have the right, but shall not be obligated, to purchase on such
Delivery Date, in such proportion as may be agreed upon among them, the total
aggregate principal amount of Notes to be purchased on such Delivery Date. If
the remaining Initial Purchasers or other purchasers satisfactory to the Initial
Purchasers do not elect to purchase on such Delivery Date the aggregate
principal amount of Notes which the defaulting Initial Purchasers agreed but
failed to purchase, this Agreement (or with respect to the Optional Delivery
Date, the obligation of the Initial Purchasers to purchase the Optional Notes)
shall terminate without liability on the part of any non-defaulting Initial
Purchasers and

                                       27


the Company, except that the Company will continue to be liable for the payment
of expenses to the extent set forth in Sections 4 and 10. As used in this
Agreement, the term "Initial Purchaser" includes, for all purposes of this
Agreement unless the context requires otherwise, any party not listed in
Schedule 1 hereto who, pursuant to this Section 8, purchases Notes which a
defaulting Initial Purchaser agreed but failed to purchase.

         Nothing contained herein shall relieve a defaulting Initial Purchaser
of any liability it may have to the Company for damages caused by its default.
If other purchasers are obligated or agree to purchase the Notes of a defaulting
or withdrawing Initial Purchaser, either the remaining non-defaulting Initial
Purchasers or the Company may postpone the Delivery Date for up to seven full
business days in order to effect any changes in the Offering Memorandum or in
any other document or arrangement that, in the opinion of counsel to the Company
or counsel to the Initial Purchasers, may be necessary.

         9. TERMINATION.

         (a) The obligations of the Initial Purchasers hereunder may be
terminated by the Initial Purchasers by notice given to and received by the
Company prior to delivery of and payment for the Notes if, prior to that time:
(i) there has occurred one of the events described in Section 5(k), or (ii)
there has occurred any material adverse change in the financial markets in the
United States, any outbreak of hostilities or escalation thereof or other
calamity or crisis or any change or development involving a prospective change
in national or international political, financial or economic conditions, in
each case the effect of which is such as to make it, in the judgment of the
Representatives, impracticable to market the Notes or to enforce contracts for
the sale of the Notes, or (iii) trading in any securities of the Company has
been suspended or materially limited by the Commission or the Nasdaq National
Market, or if trading generally on the American Stock Exchange or the New York
Stock Exchange or in The Nasdaq Stock Market has been suspended or materially
limited, or minimum or maximum prices for trading have been fixed, or maximum
ranges for prices have been required, by any of said exchanges or by such system
or by order of the Commission, the National Association of Securities Dealers,
Inc. or any other governmental authority, or (iv) a banking moratorium has been
declared by either Federal or New York authorities.

         (b) If this Agreement is terminated pursuant to this Section 9, such
termination shall be without liability of any party to any other party except as
provided in Section 10 and PROVIDED, FURTHER, that Sections 1, 7 and 13 shall
survive such termination and remain in full force and effect.

         10. REIMBURSEMENT OF INITIAL PURCHASERS' EXPENSES. If (a) the Company
shall fail to tender the Notes for delivery to the Initial Purchasers for any
reason permitted under this Agreement or (b) the Initial Purchasers shall
decline to purchase the Notes for any reason permitted under this Agreement
(including the termination of this Agreement pursuant to Section 9), the Company
shall reimburse the Initial Purchasers for the fees and expenses of their
counsel and for such other out-of-pocket expenses as shall have been incurred by
them in connection with this Agreement and the proposed purchase of the Notes,
and upon demand the Company shall pay the full amount thereof to the Initial
Purchasers. If this Agreement is terminated pursuant to Section 8 by reason of
the default of one or more Initial Purchasers, the

                                       28


Company shall not be obligated to reimburse any defaulting Initial Purchaser on
account of those expenses.

         11. NOTICES, ETC. All statements, requests, notices and agreements
hereunder shall be in writing, and:

         (a) if to the Initial Purchasers, shall be delivered or sent by mail,

7(c) shall be delivered or sent by mail, telex or facsimile transmission to each
such Initial Purchaser, which address will be supplied to any other party hereto
by Lehman Brothers Inc. upon request. Any such statements, requests, notices or
agreements shall take effect at the time of receipt thereof. The Company shall
be entitled to act and rely upon any request, consent, notice or agreement given
or made on behalf of the Initial Purchasers by Merrill Lynch.

         12. PERSONS ENTITLED TO BENEFIT OF AGREEMENT. This Agreement shall
inure to the benefit of and be binding upon the Initial Purchasers, the Company
and their respective successors. This Agreement and the terms and provisions
hereof are for the sole benefit of only those persons, except that the
representations, warranties, indemnities and agreements of the Company contained
in this Agreement shall also be deemed to be for the benefit of the officers and
employees of each Initial Purchaser and the person or persons, if any, who
control each Initial Purchaser within the meaning of Section 15 of the
Securities Act and any indemnity agreement of the Initial Purchasers contained
in Section 7(b) of this Agreement shall be deemed to be for the benefit of
directors, officers and employees of the Company, and any person controlling the
Company within the meaning of Section 15 of the Securities Act. Nothing
contained in this Agreement is intended or shall be construed to give any
person, other than the persons referred to in this Section 12, any legal or
equitable right, remedy or claim under or in respect of this Agreement or any
provision contained herein.

         13. SURVIVAL. The respective indemnities, representations, warranties
and agreements of the Company and the Initial Purchasers contained in this
Agreement or made by or on behalf of them, respectively, pursuant to this
Agreement, shall survive the delivery of and payment for the Notes and shall
remain in full force and effect, regardless of any termination or cancellation
of this Agreement or any investigation made by or on behalf of any of them or
any person controlling any of them.

         14. DEFINITION OF THE TERMS "BUSINESS DAY" AND "SUBSIDIARY". For
purposes of this Agreement, (a) "business day" means any day on which the New
York Stock Exchange, Inc. is open for trading and (b) "subsidiary" has the
meaning set forth in Rule 405 of the rules and regulations promulgated under the
Securities Act.

                                       29

in accordance with, the laws of the State of New York.

         16. COUNTERPARTS. This Agreement may be executed in one or more

shall together constitute one and the same instrument.

         Deadline"), cause to be filed a registration statement pursuant to Rule
         415 under the Securities Act (the "Shelf Registration Statement"),

         practicable, but in no event later than 180 days after the date hereof
         (the "Effectiveness Target Date"); and

            (iii) use its best efforts to keep the Shelf Registration Statement
         continuously effective, supplemented and amended as required by the
         provisions of Section 4(b) hereof to the extent necessary to ensure
         that (A) it is available for resales by the Holders of Transfer
         Restricted Securities entitled to the benefit of this Agreement and (B)
         conforms with the requirements of this Agreement and the Securities Act
         and the rules and regulations of the Commission promulgated thereunder
         as announced from time to time for a period (the "Effectiveness

                                       3



                (1) two years following the last date of original issuance of
            Notes; or

                (2) such shorter period that will terminate when (x) all of the
            Holders of Transfer Restricted Securities are able to sell all
            Transfer Restricted Securities immediately without restriction
            pursuant to Rule 144(k) under the Securities Act or any successor
            rule thereto, (y) when all Transfer Restricted Securities have

            Transfer Restricted Securities registered under the Shelf
            Registration Statement have been sold.

Transfer Restricted Securities in the Shelf Registration Statement pursuant to

"Questionnaire Deadline"), such information as the Issuer may reasonably request
for use in connection with the Shelf Registration Statement or the Prospectus or
preliminary Prospectus included therein and in any application to be filed with
or under state securities laws. In connection with all such requests for
information from Holders of Transfer Restricted Securities, the Issuer shall
notify such Holders of the requirements set forth in the preceding sentence. No
Holder of Transfer Restricted Securities shall be entitled to Liquidated Damages
pursuant to Section 3 hereof unless such Holder shall have provided all such
reasonably requested information prior to or on the Questionnaire Deadline. Each
Holder as to which the Shelf Registration Statement is being effected agrees to
furnish promptly to the Issuer all information required to be disclosed in order
to make information previously furnished to the Issuer by such Holder not
materially misleading.

         3. LIQUIDATED DAMAGES.

         (a) If:

            (i) the Shelf Registration Statement is not filed with the
         Commission prior to or on the Shelf Filing Deadline;

            (ii) the Shelf Registration Statement has not been declared
         effective by the Commission prior to or on the Effective Target Date;

            (iii) subject to the provisions of Section 4(b)(i) hereof, the Shelf
         Registration Statement is filed and declared effective but, during the
         Effectiveness Period, shall thereafter cease to be effective or fail to
         be usable for its intended purpose without being succeeded within five
         Business Days by a post-effective amendment to the Shelf Registration
         Statement or a report filed with the Commission pursuant to Section
         13(a), 13(c), 14 or 15(d) of the Exchange Act that cures such failure
         and, in the case of a post-effective amendment, is itself immediately
         declared effective; or

            (iv) prior to or on the 45th or 60th day, as the case may be, of any
         Suspension Period, such suspension has not been terminated,



                                       4


         (each such event referred to in foregoing clauses (i) through (iv),
         a "Registration Default"), the Issuer hereby agrees to pay liquidated
         damages ("Liquidated Damages") with respect to the Transfer Restricted
         Securities from and including the day following the Registration
         Default to but excluding the day on which the Registration Default has
         been cured:

                (A) in respect of the Notes, to each holder of Notes, (x) with
             respect to the first 90-day period during which a Registration
             Default shall have occurred and be continuing, in an amount per
             year equal to an additional 0.25% of the principal amount of the
             Notes, and (y) with respect to the period commencing on the 91st
             day following the day the Registration Default shall have occurred
             and be continuing, in an amount per year equal to an additional
             0.50% of the principal amount of the Notes; provided that in no
             event shall Liquidated Damages accrue at a rate per year exceeding
             0.50% of the principal amount of the Notes; and

                (B) in respect of any shares of Common Stock, to each holder of
             shares of Common Stock issued upon conversion of Notes, (x) with
             respect to the first 90-day period in which a Registration Default
             shall have occurred and be continuing, in an amount per year equal
             to 0.25% of the principal amount of the converted Notes, and (y)
             with respect to the period commencing the 91st day following the
             day the Registration Default shall have occurred and be continuing,
             in an amount per year equal to 0.50% of the principal amount of the
             converted Notes; provided that in no event shall Liquidated Damages
             accrue at a rate per year exceeding 0.50% of the principal amount
             of the converted Notes.

         (b) All accrued Liquidated Damages shall be paid in arrears to Record
Holders by the Issuer on each Damages Payment Date by wire transfer of
immediately available funds or by federal funds check. Following the cure of all
Registration Defaults relating to any particular Note or share of Common Stock,
the accrual of Liquidated Damages with respect to such Note or share of Common
Stock will cease.

         All obligations of the Issuer set forth in this Section 3 that are
outstanding with respect to any Transfer Restricted Security at the time such
security ceases to be a Transfer Restricted Security shall survive until such
time as all such obligations with respect to such Transfer Restricted Security
shall have been satisfied in full.

         The Liquidated Damages set forth above shall be the exclusive monetary
remedy available to the Holders of Transfer Restricted Securities for such
Registration Default.

         4. REGISTRATION PROCEDURES.

         (a) In connection with the Shelf Registration Statement, the Issuer
shall comply with all the provisions of Section 4(b) hereof and shall use its
best efforts to effect such registration to permit the sale of the Transfer
Restricted Securities being sold in accordance with the intended method or
methods of distribution thereof, and pursuant thereto, shall as expeditiously as
possible prepare and file with the Commission a Shelf Registration Statement
relating to the registration on any appropriate form under the Securities Act.

                                       5



         (b) In connection with the Shelf Registration Statement and any
Prospectus required by this Agreement to permit the sale or resale of Transfer
Restricted Securities, the Issuer shall:

            (i) Subject to any notice by the Issuer in accordance with this
         Section 4(b) of the existence of any fact or event of the kind
         described in Section 4(b)(iii)(D), use its best efforts to keep the
         Shelf Registration Statement continuously effective during the
         Effectiveness Period; upon the occurrence of any event that would cause
         the Shelf Registration Statement or the Prospectus contained therein
         (A) to contain a material misstatement or omission or (B) not be
         effective and usable for resale of Transfer Restricted Securities
         during the Effectiveness Period, the Issuer shall file promptly an
         appropriate amendment to the Shelf Registration Statement or a report
         filed with the Commission pursuant to Section 13(a), 13(c), 14 or 15(d)
         of the Exchange Act, in the case of clause (A), correcting any such
         misstatement or omission, and, in the case of either clause (A) or (B),
         use its best efforts to cause such amendment to be declared effective
         and the Shelf Registration Statement and the related Prospectus to
         become usable for their intended purposes as soon as practicable
         thereafter. Notwithstanding the foregoing, the Issuer may suspend the
         effectiveness of the Shelf Registration Statement by written notice to
         the Holders for a period not to exceed an aggregate of 45 days in any
         90-day period (each such period, a "Suspension Period") if:

                           (x) an event occurs and is continuing as a result of
                  which the Shelf Registration Statement would, in the Issuer's
                  reasonable judgment, contain an untrue statement of a material
                  fact or omit to state a material fact required to be stated
                  therein or necessary to make the statements therein not
                  misleading; and

                           (y) the Issuer reasonably determines that the
                  disclosure of such event at such time would have a material
                  adverse effect on the business of the Issuer (and its
                  subsidiaries, if any, taken as a whole);

PROVIDED that in the event the disclosure relates to a previously undisclosed
proposed or pending material business transaction, the disclosure of which would
impede the Issuer's ability to consummate such transaction, the Issuer may
extend a Suspension Period from 45 days to 60 days; provided, however, that
Suspension Periods shall not exceed an aggregate of 90 days in any 360-day
period.

            (ii) Prepare and file with the Commission such amendments and
         post-effective amendments to the Shelf Registration Statement as may be
         necessary to keep the Shelf Registration Statement effective during the
         Effectiveness Period; cause the Prospectus to be supplemented by any
         required Prospectus supplement, and as so supplemented to be filed
         pursuant to Rule 424 under the Securities Act, and to comply fully with
         the applicable provisions of Rules 424 and 430A under the Securities
         Act in a timely manner; and comply with the provisions of the
         Securities Act with respect to the disposition of all securities
         covered by the Shelf Registration Statement during the applicable
         period in accordance with the intended method or methods of
         distribution by the sellers thereof set forth in the Shelf Registration
         Statement or supplement to the Prospectus.



                                       6



            (iii) Advise the underwriter(s), if any, and selling Holders
         promptly (but in any event within five Business Days) and, if requested
         by such Persons, to confirm such advice in writing:

                (A) when the Prospectus or any Prospectus supplement or
             post-effective amendment has been filed, and, with respect to the
             Shelf Registration Statement or any post-effective amendment
             thereto, when the same has become effective,

                (B) of any request by the Commission for amendments to the Shelf
             Registration Statement or amendments or supplements to the
             Prospectus or for additional information relating thereto,

                (C) of the issuance by the Commission of any stop order
             suspending the effectiveness of the Shelf Registration Statement
             under the Securities Act or of the suspension by any state
             securities commission of the qualification of the Transfer
             Restricted Securities for offering or sale in any jurisdiction, or
             the initiation of any proceeding for any of the preceding purposes,
             or

                (D) of the existence of any fact or the happening of any event,
             during the Effectiveness Period, that makes any statement of a
             material fact made in the Shelf Registration Statement, the
             Prospectus, any amendment or supplement thereto, or any document
             incorporated by reference therein untrue, or that requires the
             making of any additions to or changes in the Shelf Registration
             Statement or the Prospectus in order to make the statements therein
             not misleading.

If at any time the Commission shall issue any stop order suspending the
effectiveness of the Shelf Registration Statement, or any state securities
commission or other regulatory authority shall issue an order suspending the
qualification or exemption from qualification of the Transfer Restricted
Securities under state securities or Blue Sky laws, the Issuer shall use its
reasonable best efforts to obtain the withdrawal or lifting of such order at the
earliest possible time.

             (iv) Furnish to each of the selling Holders and each of the
         underwriter(s), if any, before filing with the Commission, a copy of
         the Shelf Registration Statement and copies of any Prospectus included
         therein or any amendments or supplements to the Shelf Registration
         Statement or Prospectus (other than documents incorporated by reference
         after the initial filing of the Shelf Registration Statement), which
         documents will be subject to the review of such holders and
         underwriter(s), if any, for a period of at least ten Business Days, and
         the Issuer will not file any Shelf Registration Statement or Prospectus
         or any amendment or supplement to the Shelf Registration Statement or
         Prospectus (other than documents incorporated by reference) to which a
         selling Holder of Transfer Restricted Securities covered by the Shelf
         Registration Statement or the underwriter(s), if any, shall reasonably
         object within five Business Days after the receipt thereof. A selling
         Holder or underwriter, if any, shall be deemed to have reasonably
         objected to such filing if the Shelf Registration Statement, amendment,
         Prospectus or supplement, as applicable, as proposed to be filed,
         contains a material misstatement or omission. Notwithstanding the
         foregoing, the Issuer shall not be required to furnish the selling
         Holders with any


                                       7


         amendment or supplement to the Shelf Registration Statement or
         Prospectus filed solely to reflect changes to the amount of Notes held
         by any particular Holder at the request of such Holder or immaterial
         revisions to the information contained therein.

             (v) Make available at reasonable times for inspection by one or
         more representatives of the selling Holders, designated in writing by a
         Majority of Holders whose Transfer Restricted Securities are included
         in the Shelf Registration Statement, any underwriter participating in
         any distribution pursuant to the Shelf Registration Statement, and any
         attorney or accountant retained by such selling Holders or any of the
         underwriter(s), all financial and other records, pertinent corporate
         documents and properties of the Issuer as shall be reasonably necessary
         to enable them to exercise any applicable due diligence
         responsibilities, and cause the Issuer's officers, directors, managers
         and employees to supply all information reasonably requested by any
         such representative or representatives of the selling Holders,
         underwriter, attorney or accountant in connection with the Shelf
         Registration Statement after the filing thereof and before its
         effectiveness; provided, however, that any information designated by
         the Company as confidential at the time of delivery of such information
         shall be kept confidential by the recipient thereof.

             (vi) If requested by any selling Holders or the underwriter(s), if
         any, promptly incorporate in the Shelf Registration Statement or
         Prospectus, pursuant to a supplement or post-effective amendment if
         necessary, such information as such selling Holders and underwriter(s),
         if any, may reasonably request to have included therein, including,
         without limitation: (1) information relating to the "Plan of
         Distribution" of the Transfer Restricted Securities, (2) information
         with respect to the principal amount of Notes or number of shares of
         Common Stock being sold to such underwriter(s), (3) the purchase price
         being paid therefor and (4) any other terms of the offering of the
         Transfer Restricted Securities to be sold in such offering; and make
         all required filings of such Prospectus supplement or post-effective
         amendment as soon as reasonably practicable after the Issuer is
         notified of the matters to be incorporated in such Prospectus
         supplement or post-effective amendment. Notwithstanding the foregoing,
         following the effective date of the Shelf Registration Statement, the
         Issuer shall not be required to file more than one such supplement or
         post-effective amendment to reflect changes in the amount of Notes held
         by any particular Holder at the request of such Holder in any 30-day
         period.

             (vii) Furnish to each selling Holder and each of the
         underwriter(s), if any, without charge, at least one copy of the
         Shelf Registration Statement, as first filed with the Commission,
         and of each amendment thereto (and any documents incorporated by
         reference therein or exhibits thereto (or exhibits incorporated in
         such exhibits by reference) as such Person may request).

             (viii) Deliver to each selling Holder and each of the
         underwriter(s), if any, without charge, as many copies of the
         Prospectus (including each preliminary prospectus) and any amendment or
         supplement thereto as such Persons reasonably may request; subject to
         any notice by the Issuer in accordance with this Section 4(b) of the
         existence of any fact or event of the kind described in Section
         4(b)(iii)(D), the Issuer hereby consents to the use of the Prospectus
         and any amendment or supplement thereto by each of the


                                       8



         selling Holders and each of the underwriter(s), if any, in connection
         with the offering and the sale of the Transfer Restricted Securities
         covered by the Prospectus or any amendment or supplement thereto.

             (ix) If an underwriting agreement is entered into and the
         registration is an Underwritten Registration, the Issuer shall:

                 (A) upon request, furnish to each selling Holder and each
             underwriter, in such substance and scope as they may reasonably
             request and as are customarily made by issuers to underwriters in
             primary underwritten offerings, upon the date of closing of any
             sale of Transfer Restricted Securities in an Underwritten
             Registration:

                     (1) a certificate, dated the date of such closing, signed
                 by the Chief Financial Officer of the Issuer confirming, as of
                 the date thereof, the matters set forth in Section 5(g) of the
                 Purchase Agreement and such other matters as such parties may
                 reasonably request;

                     (2) opinions, each dated the date of such closing, of
                 counsel to the Issuer covering such of the matters set forth in
                 Sections 5(c) and 5(d) of the Purchase Agreement as are
                 customarily covered in legal opinions to underwriters in
                 connection with primary underwritten offerings of securities;
                 and

                     (3) customary comfort letters, dated the date of such
                 closing, from the Issuer's independent certified public
                 accountants (and from any other accountants whose report is
                 contained or incorporated by reference in the Shelf
                 Registration Statement), in the customary form and covering
                 matters of the type customarily covered in comfort letters to
                 underwriters in connection with primary underwritten offerings
                 of securities;

                 (B) set forth in full in the underwriting agreement, if any,
             indemnification provisions and procedures which provide rights no
             less protective than those set forth in Section 6 hereof with
             respect to all parties to be indemnified; and

                 (C) deliver such other documents and certificates as may be
             reasonably requested by such parties to evidence compliance with
             clause (A) above and with any customary conditions contained in the
             underwriting agreement or other agreement entered into by the
             selling Holders pursuant to this clause (ix).

             (x) Before any public offering of Transfer Restricted Securities,
         cooperate with the selling Holders, the underwriter(s), if any, and
         their respective counsel in connection with the registration and
         qualification of the Transfer Restricted Securities under the
         securities or Blue Sky laws of such jurisdictions as the selling
         Holders or underwriter(s), if any, may reasonably request and do any
         and all other acts or things necessary or advisable to enable the
         disposition in such jurisdictions of the Transfer Restricted Securities
         covered by the Shelf Registration Statement; provided, however,


                                       9


         that the Issuer shall not be required (A) to register or qualify as a
         foreign corporation or a dealer of securities where it is not now so
         qualified or to take any action that would subject it to the service of
         process in any jurisdiction where it is not now so subject or (B) to
         subject themselves to taxation in any such jurisdiction if they are not
         now so subject.

             (xi) Cooperate with the selling Holders and the underwriter(s), if
         any, to facilitate the timely preparation and delivery of certificates
         representing Transfer Restricted Securities to be sold and not bearing
         any restrictive legends (unless required by applicable securities
         laws); and enable such Transfer Restricted Securities to be in such
         denominations and registered in such names as the Holders or the
         underwriter(s), if any, may request at least two Business Days before
         any sale of Transfer Restricted Securities made by such underwriter(s).

             (xii) Use its best efforts to cause the Transfer Restricted
         Securities covered by the Shelf Registration Statement to be registered
         with or approved by such other U.S. governmental agencies or
         authorities as may be necessary to enable the seller or sellers thereof
         or the underwriter(s), if any, to consummate the disposition of such
         Transfer Restricted Securities.

             (xiii) Subject to Section 4(b)(i) hereof, if any fact or event
         contemplated by Section 4(b)(iii)(D) hereof shall exist or have
         occurred, use its reasonable best efforts to prepare a supplement or
         post-effective amendment to the Shelf Registration Statement or related
         Prospectus or any document incorporated therein by reference or file
         any other required document so that, as thereafter delivered to the
         purchasers of Transfer Restricted Securities, the Prospectus will not
         contain an untrue statement of a material fact or omit to state any
         material fact required to be stated therein or necessary to make the
         statements therein not misleading.

             (xiv) Provide CUSIP numbers for all Transfer Restricted Securities
         not later than the effective date of the Shelf Registration Statement
         and provide the Trustee under the Indenture with certificates for the
         Notes that are in a form eligible for deposit with The Depository Trust
         Company.

             (xv) Cooperate and assist in any filings required to be made with
         the NASD and in the performance of any due diligence investigation by
         any underwriter that is required to be retained in accordance with the
         rules and regulations of the NASD.

             (xvi) Otherwise use its best efforts to comply with all applicable
         rules and regulations of the Commission and all reporting requirements
         under the rules and regulations of the Exchange Act.

             (xvii) Cause the Indenture to be qualified under the TIA not later
         than the effective date of the Shelf Registration Statement required by
         this Agreement, and, in connection therewith, cooperate with the
         trustee and the holders of Notes to effect such changes to the
         Indenture as may be required for such Indenture to be so qualified in
         accordance with the terms of the TIA; and execute and use its best
         efforts to cause the trustee thereunder to execute all documents that
         may be required to effect such changes


                                       10



         and all other forms and documents required to be filed with the
         Commission to enable such Indenture to be so qualified in a timely
         manner.

             (xviii) Cause all Transfer Restricted Securities covered by the
         Shelf Registration Statement to be listed or quoted, as the case may
         be, on each securities exchange or automated quotation system on which
         similar securities issued by the Issuer are then listed or quoted.

             (xix) Provide promptly to each Holder upon written request each
         document filed with the Commission pursuant to the requirements of
         Section 13 and Section 15 of the Exchange Act after the effective date
         of the Shelf Registration Statement.

             (xx) If requested by the underwriters, make appropriate officers of
         the Issuer available to the underwriters for meetings with prospective
         purchasers of the Transfer Restricted Securities and prepare and
         present to potential investors customary "road show" material in a
         manner consistent with other new issuances of other securities similar
         to the Transfer Restricted Securities.

         (c) Each Holder agrees by acquisition of a Transfer Restricted Security
that, upon receipt of any notice from the Issuer of the existence of any fact of
the kind described in Section 4(b)(iii)(D) hereof, such Holder will, and will
use its reasonable best efforts to cause any underwriter(s) in an Underwritten
Offering to, forthwith discontinue disposition of Transfer Restricted Securities
pursuant to the Shelf Registration Statement until:

             (i) such Holder has received copies of the supplemented or amended
         Prospectus contemplated by Section 4(b)(xiii) hereof; or

             (ii) such Holder is advised in writing (the "Advice") by the Issuer
         that the use of the Prospectus may be resumed, and has received copies
         of any additional or supplemental filings that are incorporated by
         reference in the Prospectus.

If so directed by the Issuer, each Holder will deliver to the Issuer (at the
Issuer's expense) all copies, other than permanent file copies then in such
Holder's possession, of the Prospectus covering such Transfer Restricted
Securities that was current at the time of receipt of such notice of suspension.

         (d) Each Holder who intends to be named as a selling Holder in the
Shelf Registration Statement shall furnish to the Issuer in writing, within 20
Business Days after receipt of a request therefor as set forth in a
questionnaire, such information regarding such Holder and the proposed
distribution by such Holder of its Transfer Restricted Securities as the Issuer
may reasonably request for use in connection with the Shelf Registration
Statement or Prospectus or preliminary Prospectus included therein. (The form of
the questionnaire is attached hereto as Exhibit A.) Holders that do not complete
the questionnaire and deliver it to the Issuer shall not be named as selling
securityholders in the Prospectus or preliminary Prospectus included in the
Shelf Registration Statement and therefore shall not be permitted to sell any
Transfer Restricted Securities pursuant to the Shelf Registration Statement.
Each Holder who intends to be named as a selling Holder in the Shelf
Registration Statement shall promptly furnish to the Issuer in writing such
other information as the Issuer may from time to time reasonably request in
writing.



                                       11


         (e) Upon the effectiveness of the Shelf Registration Statement, each
Holder shall notify the Issuer at least three Business Days prior to any
intended distribution of Transfer Restricted Securities pursuant to the Shelf
Registration Statement (a "Sale Notice"), which notice shall be effective for
five Business Days. Each Holder of this Security, by accepting the same, agrees
to hold any communication by the Company in response to a Sale Notice in
confidence.

         5. REGISTRATION EXPENSES.

         (a) All expenses incident to the Issuer's performance of or compliance
with this Agreement shall be borne by the Issuer regardless of whether a Shelf
Registration Statement becomes effective, including, without limitation:

             (i) all registration and filing fees and expenses (including
         filings made by any Initial Purchasers or Holders with the NASD);

             (ii) all fees and expenses of compliance with federal securities
         and state Blue Sky or securities laws;

         and certificates for the Common Stock to be issued upon conversion of
         the Notes), messenger and delivery services and telephone;

             (iv) all fees and disbursements of counsel to the Issuer and,
         subject to Section 5(b) below, the Holders of Transfer Restricted
         Securities;

             (v) all application and filing fees in connection with listing (or
         authorizing for quotation) the Common Stock on a national securities
         exchange or automated quotation system pursuant to the requirements
         hereof; and

             (vi) all fees and disbursements of independent certified public
         accountants of the Issuer (including the expenses of any special audit
         and comfort letters required by or incident to such performance).

         The Issuer shall bear its internal expenses (including, without
limitation, all salaries and expenses of their officers and employees performing
legal, accounting or other duties), the expenses of any annual audit and the
fees and expenses of any Person, including special experts, retained by the
Issuer.

         (b) In connection with the Shelf Registration Statement required by
this Agreement, the Issuer shall reimburse the Initial Purchasers and the
Holders of Transfer Restricted Securities being registered pursuant to the Shelf
Registration Statement, as applicable, for the reasonable fees and disbursements
of not more than one counsel, which shall be Brown & Wood LLP, or such other
counsel as may be chosen by a Majority of Holders for whose benefit the Shelf
Registration Statement is being prepared.



                                       12



         6. INDEMNIFICATION AND CONTRIBUTION.

         (a) The Issuer shall indemnify and hold harmless each Holder, such
Holder's officers and employees and each person, if any, who controls such
Holder within the meaning of the Securities Act (each, an "Indemnified Holder"),
from and against any loss, claim, damage or liability, joint or several, or any
action in respect thereof (including, but not limited to, any loss, claim,
damage, liability or action relating to resales of the Transfer Restricted
Securities), to which such Indemnified Holder may become subject, insofar as any
such loss, claim, damage, liability or action arises out of, or is based upon:

             (i) any untrue statement or alleged untrue statement of a material
         fact contained in (A) the Shelf Registration Statement or Prospectus or
         any amendment or supplement thereto or (B) any blue sky application or
         other document or any amendment or supplement thereto prepared or
         executed by the Issuer (or based upon written information furnished by
         or on behalf of the Issuer expressly for use in such blue sky
         application or other document or amendment on supplement) filed in any
         jurisdiction specifically for the purpose of qualifying any or all of
         the Transfer Restricted Securities under the securities law of any
         state or other jurisdiction (such application or document being
         hereinafter called a "Blue Sky Application"); or

             (ii) the omission or alleged omission to state therein any material
         fact required to be stated therein or necessary to make the statements
         therein, in the light of the circumstances under which they were made,
         not misleading,

and shall reimburse each Indemnified Holder promptly upon demand for any legal
or other expenses reasonably incurred by such Indemnified Holder in connection
with investigating or defending or preparing to defend against any such loss,
claim, damage, liability or action as such expenses are incurred; provided,
however, that the Issuer shall not be liable in any such case to the extent that
any such loss, claim, damage, liability or action arises out of, or is based
upon, any untrue statement or alleged untrue statement or omission or alleged
omission made in the Shelf Registration Statement or Prospectus or amendment or
supplement thereto or Blue Sky Application in reliance upon and in conformity
with written information furnished to the Issuer by or on behalf of any Holder
(or its related Indemnified Holder) specifically for use therein. The foregoing
indemnity agreement is in addition to any liability which the Issuer may
otherwise have to any Indemnified Holder.

         (b) Each Holder, severally and not jointly, shall indemnify and hold
harmless the Issuer, its officers and employees and each person, if any, who
controls the Issuer within the meaning of the Securities Act, from and against
any loss, claim, damage or liability, joint or several, or any action in respect
thereof, to which the Issuer or any such officer, employee or controlling person
may become subject, insofar as any such loss, claim, damage or liability or
action arises out of, or is based upon:

             (i) any untrue statement or alleged untrue statement of any
         material fact contained in the Shelf Registration Statement or
         Prospectus or any amendment or supplement thereto or any Blue Sky
         Application; or


                                       13



             (ii) the omission or the alleged omission to state therein any
         material fact required to be stated therein or necessary to make the
         statements therein, in light of the circumstances under which they were
         made, not misleading,

but in each case only to the extent that such untrue statement or alleged untrue
statement or omission or alleged omission was made in reliance upon and in
conformity with written information furnished to the Issuer by or on behalf of
such Holder (or its related Indemnified Holder) specifically for use therein,
and shall reimburse the Issuer and any such officer, employee or controlling
person promptly upon demand for any legal or other expenses reasonably incurred
by the Issuer or any such officer, employee or controlling person in connection
with investigating or defending or preparing to defend against any such loss,
claim, damage, liability or action as such expenses are incurred. The foregoing
indemnity agreement is in addition to any liability which any Holder may
otherwise have to the Issuer and any such officer, employee or controlling
person.

         (c) Promptly after receipt by an indemnified party under this Section 6
of notice of any claim or the commencement of any action, the indemnified party
shall, if a claim in respect thereof is to be made against the indemnifying
party under this Section 6, notify the indemnifying party in writing of the
claim or the commencement of that action; provided, however, that the failure to
notify the indemnifying party shall not relieve it from any liability which it
may have under this Section 6 except to the extent it has been materially
prejudiced by such failure and, provided, further, that the failure to notify
the indemnifying party shall not relieve it from any liability which it may have
to an indemnified party otherwise than under this Section 6. If any such claim
or action shall be brought against an indemnified party, and it shall notify the
indemnifying party thereof, the indemnifying party shall be entitled to
participate therein and, to the extent that it wishes, jointly with any other
similarly notified indemnifying party, to assume the defense thereof with
counsel satisfactory to the indemnified party. After notice from the
indemnifying party to the indemnified party of its election to assume the
defense of such claim or action, the indemnifying party shall not be liable to
the indemnified party under this Section 6 for any legal or other expenses
subsequently incurred by the indemnified party in connection with the defense
thereof other than reasonable costs of investigation; provided, however, that a
Majority of Holders shall have the right to employ a single counsel to represent
jointly a Majority of Holders and their respective officers, employees and
controlling persons who may be subject to liability arising out of any claim in
respect of which indemnity may be sought by a Majority of Holders against the
Issuer under this Section 6, if a Majority of Holders shall have reasonably
concluded that there may be one or more legal defenses available to them and
their respective officers, employees and controlling persons that are different
from or additional to those available to the Issuer and its officers, employees
and controlling persons, the fees and expenses of a single separate counsel
shall be paid by the Issuer. No indemnifying party shall:

             (i) without the prior written consent of the indemnified parties
         (which consent shall not be unreasonably withheld) settle or compromise
         or consent to the entry of any judgment with respect to any pending or
         threatened claim, action, suit or proceeding in respect of which
         indemnification or contribution may be sought hereunder (whether or not
         the indemnified parties are actual or potential parties to such claim
         or action) unless such settlement, compromise or consent (1) includes
         an unconditional release of each


                                       14


         indemnified party from all liability arising out of such claim, action,
         suit or proceeding and (2) does not include a statement as to or an
         admission of fault, culpability or a failure to act by or on behalf of
         any indemnified party, or

             (ii) be liable for any settlement of any such action effected
         without its written consent (which consent shall not be unreasonably
         withheld), but if settled with its written consent or if there be a
         final judgment for the plaintiff in any such action, the indemnifying
         party agrees to indemnify and hold harmless any indemnified party from
         and against any loss of liability by reason of such settlement or
         judgment.

         (d) If the indemnification provided for in this Section 6 shall for any
reason be unavailable or insufficient to hold harmless an indemnified party
under Section 6(a) or 6(b) in respect of any loss, claim, damage or liability
(or action in respect thereof) referred to therein, each indemnifying party
shall, in lieu of indemnifying such indemnified party, contribute to the amount
paid or payable by such indemnified party as a result of such loss, claim,
damage or liability (or action in respect thereof):

             (i) in such proportion as is appropriate to reflect the relative
         benefits received by the Issuer from the offering and sale of the
         Transfer Restricted Securities on the one hand and a Holder with
         respect to the sale by such Holder of the Transfer Restricted
         Securities on the other, or

             (ii) if the allocation provided by clause (6)(d)(i) is not
         permitted by applicable law, in such proportion as is appropriate to
         reflect not only the relative benefits referred to in clause 6(d)(i)
         but also the relative fault of the Issuer on the one hand and the
         Holders on the other in connection with the statements or omissions or
         alleged statements or alleged omissions that resulted in such loss,
         claim, damage or liability (or action in respect thereof), as well as
         any other relevant equitable considerations.

         The relative benefits received by the Issuer on the one hand and a
Holder on the other with respect to such offering and such sale shall be deemed
to be in the same proportion as the total net proceeds from the offering of the
Notes purchased under the Purchase Agreement (before deducting expenses)
received by the Issuer as set forth in the table on the cover of the Offering
Memorandum, dated October 11, 2000, on the one hand, bear to the total proceeds
received by such Holder with respect to its sale if Transfer Restricted
Securities on the other.

         The relative fault of the parties shall be determined by reference to
whether the untrue or alleged untrue statement of a material fact or the
omission or alleged omission to state a material fact relates to information
supplied by the Issuer on the one hand or the Holders on the other, the intent
of the parties and their relative knowledge, access to information and
opportunity to correct or prevent such statement or omission.

         The Issuer and each Holder agree that it would not be just and
equitable if the amount of contribution pursuant to this Section 6(d) were
determined by pro rata allocation or by any other method of allocation that does
not take into account the equitable considerations referred to in the first
sentence of this paragraph (d). The amount paid or payable by an indemnified
party as a result of the loss, claim, damage or liability, or action in respect
thereof, referred to above in this



                                       15



Section 6 shall be deemed to include, for purposes of this Section 6, any legal
or other expenses reasonably incurred by such indemnified party in connection
with investigating, or defending or preparing to defend any such litigation,
investigation or proceeding by any governmental agency or body, or commenced or
threatened action or claim. Notwithstanding the provisions of this Section 6, no
Holder shall be required to contribute any amount in excess of the amount by
which the total price at which the Transfer Restricted Securities purchased by
it were resold exceeds the amount of any damages which such Holder has otherwise
been required to pay by reason of any untrue or alleged untrue statement or
omission or alleged omission.

         No person guilty of fraudulent misrepresentation (within the meaning of
Section 11(f) of the Securities Act) shall be entitled to contribution from any
person who was not guilty of such fraudulent misrepresentation. The Holders'
obligations to contribute as provided in this Section 6(d) are several and not
joint.

         7. RULE 144A. In the event the Issuer is not subject to Section 13 or
15(d) of the Exchange Act, the Issuer hereby agrees with each Holder, for so
long as any Transfer Restricted Securities remain outstanding, to make available
to any Holder or beneficial owner of Transfer Restricted Securities in
connection with any sale thereof and any prospective purchaser of such Transfer
Restricted Securities from such Holder or beneficial owner, the information
required by Rule 144A(d)(4) under the Securities Act in order to permit resales
of such Transfer Restricted Securities pursuant to Rule 144A.

         8. PARTICIPATION IN UNDERWRITTEN REGISTRATIONS. No Holder may
participate in any Underwritten Registration hereunder unless such Holder:

             (i) agrees to sell such Holder's Transfer Restricted Securities on
         the basis provided in any underwriting arrangements approved by the
         Persons entitled hereunder to approve such arrangements and

             (ii) completes and executes all reasonable questionnaires, powers
         of attorney, indemnities, underwriting agreements, lock-up letters and
         other documents required under the terms of such underwriting
         arrangements.

         9. SELECTION OF UNDERWRITERS. The Holders of Transfer Restricted
Securities covered by the Shelf Registration Statement who desire to do so may
sell such Transfer Restricted Securities in an Underwritten Offering. In any
such Underwritten Offering, the investment banker or investment bankers and
manager or managers that will administer the offering will be selected by a
Majority of Holders whose Transfer Restricted Securities are included in such
offering; provided, that such investment bankers and managers must be reasonably
satisfactory to the Issuer.

         10. MISCELLANEOUS.

         (a) REMEDIES. The Issuer acknowledges and agrees that any failure by
the Issuer to comply with its obligations under Section 2 hereof may result in
material irreparable injury to the Initial Purchasers or the Holders for which
there is no adequate remedy at law, that it will not be possible to measure
damages for such injuries precisely and that, in the event of any such failure,
the Initial Purchasers or any Holder may obtain such relief as may be required
to specifically


                                       16



enforce the Issuer's obligations under Section 2 hereof. The
Issuer further agrees to waive the defense in any action for specific
performance that a remedy at law would be adequate.

         (b) ADJUSTMENTS AFFECTING TRANSFER RESTRICTED SECURITIES. The Issuer
shall not, directly or indirectly, take any action with respect to the Transfer
Restricted Securities as a class that would adversely affect the ability of the
Holders of Transfer Restricted Securities to include such Transfer Restricted
Securities in a registration undertaken pursuant to this Agreement.

         (c) NO INCONSISTENT AGREEMENTS. The Issuer will not, on or after the
date of this Agreement, enter into any agreement with respect to its securities
that is inconsistent with the rights granted to the Holders in this Agreement or
otherwise conflicts with the provisions hereof. In addition, the Issuer shall
not grant to any of its security holders (other than the holders of Transfer
Restricted Securities in such capacity) the right to include any of its
securities in the Shelf Registration Statement provided for in this Agreement
other than the Transfer Restricted Securities. Other than the Stock Purchase
Agreement, dated January 18, 1995, between the Issuer and Pfizer, Inc., the
Stock Purchase Agreement, dated March 1, 1996, as amended, between the Issuer
and Baxter Healthcare Corporation and the Stock Issuance Agreement, dated
November 4, 1999, between the Issuer and Alliance Pharmaceutical Corp., the
Issuer has not previously entered into any agreement (which has not expired or
been terminated) granting any registration rights with respect to its securities
to any Person which rights conflict with the provisions hereof.

         (d) AMENDMENTS AND WAIVERS. This Agreement may not be amended, modified
or supplemented, and waivers or consents to or departures from the provisions
hereof may not be given, unless the Issuer has obtained the written consent of a
Majority of Holders.

         (e) NOTICES. All notices and other communications provided for or
permitted hereunder shall be made in writing by hand-delivery, first-class mail

consent or approval of Holders of a specified percentage of Transfer Restricted
Securities is required hereunder, Transfer Restricted Securities held by the

Securities Act) shall not be counted in determining whether such consent or
approval was given by the Holders of such required percentage.

         (i) HEADINGS. The headings in this Agreement are for convenience of
reference only and shall not limit or otherwise affect the meaning hereof.

         (j) GOVERNING LAW. This Agreement shall be governed by, and construed
in accordance with, the law of the State of New York, without regard to conflict
of laws principles thereof.

         (k) SEVERABILITY. If any one or more of the provisions contained
herein, or the application thereof in any circumstance, is held invalid, illegal
or unenforceable, the validity, legality and enforceability of any such
provision in every other respect and of the remaining provisions contained
herein shall not be affected or impaired thereby.

         (l) ENTIRE AGREEMENT. This Agreement is intended by the parties as a
final expression of their agreement and intended to be a complete and exclusive
statement of the agreement and understanding of the parties hereto in respect of
the subject matter contained herein. There are no restrictions, promises,
warranties or undertakings, other than those set forth or referred to


                                       18

                        INHALE THERAPEUTIC SYSTEMS, INC.

         FORM OF SELLING SECURITYHOLDER NOTICE AND QUESTIONNAIRE

         The undersigned beneficial holder of 3 1/2% Convertible Subordinated
Notes due 2007 (the "Notes") of Inhale TherapeutIC Systems, Inc. (the "Issuer"),
or common stock, par value $0.0001 per share (the "Shares" and together with the
Notes, the "Transfer Restricted Securities") of the Issuer understands that the
Issuer has filed, or intends to file, with the Securities and Exchange
Commission (the "Commission") a registration statement (the "Shelf Registration
Statement"), for the registration and resale under Rule 415 of the Securities
Act of 1933, as amended (the "Securities Act"), of the Transfer Restricted
Securities in accordance with the terms of the Registration Rights Agreement,
dated as of October 17, 2000 (the "Registration Rights Agreement") between the
Issuer and Merrill Lynch, Pierce, Fenner & Smith Incorporated, Lehman Brothers
Inc., Deutsche Bank Securities Inc. and U.S. Bancorp Piper Jaffray Inc. A copy
of the Registration Rights Agreement is available from the Issuer upon request
at the address set forth below. All capitalized terms not otherwise defined
herein have the meaning ascribed thereto in the Registration Rights Agreement.

         Each beneficial owner of Transfer Restricted Securities is entitled to
the benefits of the Registration Rights Agreement. In order to sell or otherwise
dispose of any Transfer Restricted Securities pursuant to the Shelf Registration
Statement, a beneficial owner of Transfer Restricted Securities generally will
be required to be named as a selling securityholder in the related Prospectus,
deliver a Prospectus to purchasers of Transfer Restricted Securities and be
bound by those provisions of the Registration Rights Agreement applicable to
such beneficial owner (including certain indemnification provisions, as
described below). BENEFICIAL OWNERS THAT DO NOT COMPLETE THIS NOTICE AND
QUESTIONNAIRE WITHIN 20 BUSINESS DAYS OF RECEIPT HEREOF AND DELIVER IT TO THE
ISSUER AS PROVIDED BELOW WILL NOT BE NAMED AS SELLING SECURITYHOLDERS IN THE
PROSPECTUS AND THEREFORE WILL NOT BE PERMITTED TO SELL ANY TRANSFER RESTRICTED
SECURITIES PURSUANT TO THE SHELF REGISTRATION STATEMENT.

         Certain legal consequences arise from being named as a selling
securityholder in the Shelf Registration Statement and the related Prospectus.
Accordingly, holders and beneficial owners of Transfer Restricted Securities are
advised to consult their own securities law counsel regarding the consequences
of being named or not being named as a selling securityholder in the Shelf
Registration Statement and the related Prospectus.

                                     NOTICE

pledge Transfer Restricted Securities to broker-dealers that in turn may sell
such securities.

State any exceptions here:

Note: In no event will such method(s) of distribution take the form of an
underwritten offering of the Transfer Restricted Securities without the prior

         The Company has duly authorized the creation of an issue of its 3 1/2%

                  NOW, THEREFORE, THIS INDENTURE WITNESSETH:

         For and in consideration of the premises and the purchase of the
Securities by the Holders thereof, it is mutually covenanted and agreed, for the

                                   ARTICLE 1

                          DEFINITIONS AND INCORPORATION
                                  BY REFERENCE

SECTION 1.1       DEFINITIONS.

         For all purposes of this Indenture and the Securities, the following
terms are defined as follows:

                 "Act", when used with respect to any Holder of a Security, has
         the meaning specified in Section 14.4(a) hereof.

                 "Adjusted Interest Rate" means, with respect to any Reset
         Transaction, the rate per annum that is the arithmetic average of the
         rates quoted by two Reference Dealers selected by the Company or its
         successor as the rate at which interest on the Securities should accrue
         so that the fair market value, expressed in dollars, of a Security
         immediately after the later of:

                           (1) the public announcement of such Reset
         Transaction; or

                           (2) the public announcement of a change in dividend
         policy in connection with such Reset Transaction,

will equal the average Trading Price of a Security for the 20 Trading Days
preceding the date of public announcement of such Reset Transaction; provided
that the Adjusted Interest Rate shall not be less than 5% per annum.

                 "Affiliate" of any specified Person means any other Person
         directly or indirectly controlling or controlled by or under direct or
         indirect common control with such specified Person. For the purposes of
         this definition, "control", when used with respect to any specified
         Person, means the power to direct the management and policies of such
         Person, directly or indirectly, whether through the ownership of voting
         securities, by contract or otherwise; and the terms "controlling" and
         "controlled" have meanings correlative to the foregoing.

                 "Bankruptcy Law" means Title 11 of the U.S. Code or any similar
         federal or state law for the relief of debtors.

                 "Board of Directors" means either the board of directors of the
         Company or any committee of that board empowered to act for it with
         respect to this Indenture.

                                 THE SECURITIES

         SECTION 2.1       TITLE AND TERMS.

         The Securities shall be known and designated as the "3 1/2% Convertible
Subordinated Notes due 2007"of the Company. The aggregate principal amount of
Securities which may be authenticated and delivered under this Indenture is
limited to $200,000,000 (or $250,000,000 if the over-allotment option set forth
in Section 2 of the Purchase Agreement is exercised in full), except for
securities authenticated and delivered upon registration of, transfer of, or in
exchange for, or in lieu of other Securities pursuant to Section 2.7, 2.8, 2.9,
2.12, 7.5, 10.8, 11.1 or 12.2 hereof. The Securities shall be issuable in
denominations of $1,000 or integral multiples thereof.

         The Securities shall mature on October 17, 2007.

         Interest shall accrue from October 17, 2000 at the Interest Rate until
the principal thereof is paid or made available for payment. Interest shall be
payable semiannually in arrears on April 17 and October 17, in each year,
commencing April 17, 2001.

         Interest on the Securities shall be computed (i) for any full
semiannual period for which a particular Interest Rate is applicable on the
basis of a 360-day year of twelve 30-day months and (ii) for any period for
which a particular Interest Rate is applicable shorter than a full semiannual
period for which interest is calculated, on the basis of a 30-day month and, for
such periods of less than a month, the actual number of days elapsed over a
30-day month. For purposes of determining the Interest Rate, the Trustee may
assume that a Reset Transaction has not occurred unless the Trustee has received
an Officers' Certificate stating that a Reset Transaction has occurred and

         A Holder of any Security at the close of business on a Regular Record
Date shall be entitled to receive interest (including Liquidated Damages, if
any) on such Security on the corresponding Interest Payment Date. A Holder of
any Security which is converted after the close of business on a Regular Record
Date and prior to the corresponding Interest Payment Date (other than any
Security whose Maturity is prior to such Interest Payment Date) shall be
entitled to receive interest (including Liquidated Damages, if any) on the
principal amount of such Security, notwithstanding the conversion of such
Security prior to such Interest Payment Date. However, any such Holder which
surrenders any such Security for conversion during the period between the close
of business on such Regular Record Date and ending with the opening of business
on the corresponding Interest Payment Date shall be required to pay the Company
an amount equal to the interest (including Liquidated Damages, if any) on the
principal amount of such Security so converted, which is payable by the Company
to such Holder on such Interest Payment Date, at the time such Holder surrenders
such Security for conversion. Notwithstanding the foregoing, any such Holder
which surrenders for conversion any Security which has been called for
redemption by the Company in a notice of redemption given by the Company
pursuant to Section 10.5 hereof shall be entitled to receive (and retain) such
interest (including Liquidated Damages, if any) and need not pay the Company an
amount equal to the


                                       15



interest (including Liquidated Damages, if any) on the principal amount of
such Security so converted at the time such Holder surrenders such Security
for conversion.

         Principal of, and premium, if any, and interest on, Global Securities
shall be payable to the Depositary in immediately available funds.

         Principal and premium, if any, on Physical Securities shall be payable
at the office or agency of the Company maintained for such purpose, initially

be payable by (i) U.S. Dollar check drawn on a bank in The City of New York

appear in the Register, or (ii) upon application to the Registrar not later than
the relevant Record Date by a Holder of an aggregate principal amount in excess
of $5,000,000, wire transfer in immediately available funds.

provided in Article 10 hereof.

expressly agree to such terms and provisions and to be bound thereby.

         Any of the Securities may have such letters, numbers or other marks of

regulation made pursuant thereto or with any rule or regulation of any

in accordance with the instructions given by the Holder thereof, as hereinafter
provided.

         Securities issued in exchange for interests in the Global Securities
pursuant to Section 2.8(d) hereof shall be issued in the form of permanent
definitive Securities (the "Physical Securities") in registered form without
interest coupons. The Physical Securities shall be substantially in the form set
forth in Exhibit A annexed hereto.

         The Securities shall be typed, printed, lithographed or engraved or
produced by any combination of these methods or may be produced in any other
manner permitted by the rules of any securities exchange on which the Securities
may be listed, all as determined by the Officers executing such Securities, as
evidenced by their execution of such Securities.

than Common Stock, if any, issued upon conversion thereof which shall bear the
legend set forth in Section 2.3(a)(ii), if applicable) shall bear a Restricted
Securities Legend in substantially the following form:

         AS DEFINED IN RULE 144A UNDER THE SECURITIES ACT; (2) AGREES THAT IT
         WILL NOT WITHIN TWO YEARS AFTER THE ORIGINAL ISSUANCE OF THIS SECURITY
         RESELL OR OTHERWISE TRANSFER THE SECURITY EVIDENCED HEREBY OR THE
         COMMON STOCK ISSUABLE UPON CONVERSION OF SUCH SECURITY EXCEPT (A) TO
         THE COMPANY OR ANY SUBSIDIARY THEREOF, (B) TO A QUALIFIED INSTITUTIONAL
         BUYER IN COMPLIANCE WITH RULE 144A UNDER THE SECURITIES ACT, (C)
         PURSUANT TO THE EXEMPTION FROM REGISTRATION PROVIDED BY RULE 144 UNDER
         THE SECURITIES ACT (IF AVAILABLE) OR (D) PURSUANT TO A REGISTRATION
         STATEMENT WHICH HAS BEEN DECLARED EFFECTIVE UNDER THE SECURITIES ACT
         AND WHICH CONTINUES TO BE EFFECTIVE AT THE TIME OF SUCH TRANSFER; AND
         (3) AGREES THAT IT WILL DELIVER TO EACH PERSON TO WHOM THE SECURITY
         EVIDENCED HEREBY IS TRANSFERRED (OTHER THAN A TRANSFER PURSUANT TO
         CLAUSE 2(D) ABOVE) A NOTICE SUBSTANTIALLY TO THE EFFECT OF THIS LEGEND.
         IN CONNECTION WITH ANY TRANSFER OF THE SECURITY EVIDENCED HEREBY WITHIN
         TWO YEARS AFTER THE ORIGINAL ISSUANCE OF SUCH SECURITY (OTHER THAN A
         TRANSFER PURSUANT TO CLAUSE (2)(D) ABOVE), THE HOLDER MUST CHECK THE
         APPROPRIATE BOX SET FORTH ON THE REVERSE HEREOF RELATING TO THE MANNER
         OF SUCH TRANSFER AND SUBMIT THIS CERTIFICATE TO THE TRUSTEE (OR ANY
         SUCCESSOR TRUSTEE, AS APPLICABLE). IF THE PROPOSED TRANSFER IS PURSUANT
         TO CLAUSE (2)(C) ABOVE, THE HOLDER MUST, PRIOR TO SUCH TRANSFER,
         FURNISH TO THE TRUSTEE (OR ANY SUCCESSOR TRUSTEE, AS APPLICABLE), SUCH
         CERTIFICATIONS, LEGAL OPINIONS OR OTHER INFORMATION AS THE COMPANY MAY
         REASONABLY REQUIRE TO CONFIRM THAT SUCH TRANSFER IS BEING MADE PURSUANT
         TO AN EXEMPTION FROM, OR IN A TRANSACTION NOT SUBJECT TO, THE
         REGISTRATION REQUIREMENTS OF THE SECURITIES ACT. THIS LEGEND WILL BE
         REMOVED UPON THE EARLIER OF THE TRANSFER OF THE SECURITY EVIDENCED
         HEREBY PURSUANT TO CLAUSE (2)(D) ABOVE OR THE EXPIRATION OF TWO YEARS
         FROM THE ORIGINAL ISSUANCE OF THE SECURITY EVIDENCED HEREBY. AS USED
         HEREIN, THE TERMS "UNITED STATES" AND "U.S. PERSON" HAVE THE MEANINGS
         GIVEN TO THEM BY REGULATION S UNDER THE SECURITIES ACT.

         (ii) Restricted Securities Legend for Common Stock Issued Upon
Conversion of the Securities.


                                       18


         Until two years after the original issuance date of any Security, any
stock certificate representing Common Stock issued upon conversion of such
Security shall bear a Restricted Securities Legend in substantially the
following form:

         THE SECURITY EVIDENCED HEREBY HAS NOT BEEN REGISTERED UNDER THE
         SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES ACT"), OR ANY STATE
         SECURITIES LAWS, AND MAY NOT BE OFFERED OR SOLD WITHIN THE UNITED
         STATES OR TO, OR FOR THE ACCOUNT OR BENEFIT OF, U.S. PERSONS EXCEPT AS
         SET FORTH IN THE FOLLOWING SENTENCE. THE HOLDER HEREOF AGREES THAT
         UNTIL THE EXPIRATION OF TWO YEARS AFTER THE ORIGINAL ISSUANCE OF THE
         SECURITY UPON THE CONVERSION OF WHICH THE COMMON STOCK EVIDENCED HEREBY
         WAS ISSUED, (1) IT WILL NOT RESELL OR OTHERWISE TRANSFER THE SECURITY
         EXCEPT (A) TO THE COMPANY OR ANY SUBSIDIARY THEREOF, (B) PURSUANT TO
         THE EXEMPTION FROM REGISTRATION PROVIDED BY RULE 144 UNDER THE
         SECURITIES ACT (IF AVAILABLE) OR (C) PURSUANT TO A REGISTRATION
         STATEMENT WHICH HAS BEEN DECLARED EFFECTIVE UNDER THE SECURITIES ACT
         AND WHICH CONTINUES TO BE EFFECTIVE AT THE TIME OF SUCH TRANSFER; (2)
         PRIOR TO ANY SUCH TRANSFER OTHER THAN A TRANSFER PURSUANT TO CLAUSE
         1(C) ABOVE, IT WILL FURNISH TO SUCH TRANSFER AGENT (OR ANY SUCCESSOR
         TRANSFER AGENT, AS APPLICABLE), SUCH CERTIFICATIONS, LEGAL OPINIONS OR
         OTHER INFORMATION AS THE COMPANY MAY REASONABLY REQUIRE TO CONFIRM THAT
         SUCH TRANSFER IS BEING MADE PURSUANT TO AN EXEMPTION FROM, OR IN A
         TRANSACTION NOT SUBJECT TO, THE REGISTRATION REQUIREMENTS OF THE
         SECURITIES ACT; AND (3) IT WILL DELIVER TO EACH PERSON TO WHOM THE
         COMMON STOCK EVIDENCED HEREBY IS TRANSFERRED (OTHER THAN A TRANSFER
         PURSUANT TO A CLAUSE (1)(C) ABOVE) A NOTICE SUBSTANTIALLY TO THE EFFECT
         OF THIS LEGEND. THIS LEGEND WILL BE REMOVED UPON THE EARLIER OF THE
         TRANSFER OF THE COMMON STOCK EVIDENCED HEREBY PURSUANT TO CLAUSE (1)(C)
         ABOVE OR THE EXPIRATION OF TWO YEARS FROM THE ORIGINAL ISSUANCE OF THE
         SECURITY UPON THE CONVERSION OF WHICH THE COMMON STOCK EVIDENCED HEREBY
         WAS ISSUED. AS USED HEREIN, THE TERMS "UNITED STATES" AND "U.S. PERSON"
         HAVE THE MEANINGS GIVEN TO THEM BY REGULATION S UNDER THE SECURITIES
         ACT.

        (iii) Removal of the Restricted Securities Legends.

         Each Security or share of Common Stock issued upon conversion of such
Security shall bear the Restricted Securities Legend set forth in Section
2.3(a)(i) or 2.3(a)(ii), as the case may be, until the earlier of:

                           (A) two years after the original issuance date of
                       such Security;


                                       19


                           (B) such Security or Common Stock has been sold
                       pursuant to a registration statement that has been
                       declared effective under the Securities Act (and which
                       continues to be effective at the time of such sale);
                       or

                           (C) such Common Stock has been issued upon
                       conversion of Securities that have been sold pursuant
                       to a registration statement that has been declared
                       effective under the Securities Act (and which
                       continues to be effective at the time of such sale).

The Holder must give notice thereof to the Trustee and any transfer agent for
the Common Stock, as applicable.

         Notwithstanding the foregoing, the Restricted Securities Legend may be
removed if there is delivered to the Company such satisfactory evidence, which
may include an opinion of independent counsel, as may be reasonably required by
the Company that neither such legend nor the restrictions on transfer set forth
therein are required to ensure that transfers of such Security will not violate
the registration requirements of the Securities Act. Upon provision of such
satisfactory evidence, the Trustee, at the written direction of the Company,
shall authenticate and deliver in exchange for such Securities another Security
or Securities having an equal aggregate principal amount that does not bear such
legend. If the Restricted Securities Legend has been removed from a Security as
provided above, no other Security issued in exchange for all or any part of such
Security shall bear such legend, unless the Company has reasonable cause to
believe that such other Security is a "restricted security" within the meaning
of Rule 144 and instructs the Trustee in writing to cause a Restricted
Securities Legend to appear thereon.

         Any Security (or security issued in exchange or substitution thereof)
as to which such restrictions on transfer shall have expired in accordance with
their terms or as to which the conditions for removal of the Restricted
Securities Legend set forth in Section 2.3(a)(i) as set forth therein have been
satisfied may, upon surrender of such Security for exchange to the Registrar in
accordance with the provisions of Section 2.7 hereof, be exchanged for a new
Security or Securities, of like tenor and aggregate principal amount, which
shall not bear the Restricted Securities Legend required by Section 2.3(a)(i).

         Any such Common Stock as to which such restrictions on transfer shall
have expired in accordance with their terms or as to which the conditions for
removal of the Restricted Securities Legend set forth in Section 2.3(a)(ii) as
set forth therein have been satisfied may, upon surrender of the certificates
representing such shares of Common Stock for exchange in accordance with the
procedures of the transfer agent for the Common Stock, be exchanged for a new
certificate or certificates for a like aggregate number of shares of Common
Stock, which shall not bear the Restricted Securities Legend required by Section
2.3(a)(ii).

         (b) GLOBAL SECURITY LEGEND.

         Each Global Security shall also bear the following legend on the face
thereof:

UNLESS THIS CERTIFICATE IS PRESENTED BY AN AUTHORIZED REPRESENTATIVE OF THE
DEPOSITORY TRUST COMPANY ("DTC") TO INHALE THERAPEUTIC


                                       20



SYSTEMS, INC. (OR ITS SUCCESSOR) OR ITS AGENT FOR REGISTRATION OF TRANSFER,
EXCHANGE, CONVERSION OR PAYMENT, AND ANY CERTIFICATE ISSUED IS REGISTERED IN THE
NAME OF CEDE & CO. OR IN SUCH OTHER ENTITY AS IS REQUESTED BY AN AUTHORIZED
REPRESENTATIVE OF DTC (AND ANY PAYMENT HEREON IS MADE TO CEDE & CO. OR TO SUCH
OTHER ENTITY AS IS REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF DTC), ANY
TRANSFER, PLEDGE OR OTHER USE HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON
IS WRONGFUL SINCE THE REGISTERED OWNER HEREOF, CEDE & CO., HAS AN INTEREST
HEREIN.

         SECTION 2.4       EXECUTION, AUTHENTICATION, DELIVERY AND DATING.

         Two Officers shall execute the Securities on behalf of the Company by
manual or facsimile signature. If an Officer whose signature is on a Security no
longer holds that office at the time the Security is authenticated, the Security
shall be valid nevertheless.

         At any time and from time to time after the execution and delivery of
this Indenture, the Company may deliver Securities executed by the Company to
the Trustee for authentication, together with a Company Order for the
authentication and delivery of such Securities, and the Trustee in accordance
with such Company Order shall authenticate and deliver such Securities as in
this Indenture provided and not otherwise.

         Each Security shall be dated the date of its authentication.

         No Security shall be entitled to any benefit under this Indenture, or
be valid or obligatory for any purpose, unless there appears on such Security a
certificate of authentication substantially in the form provided for herein
executed by or on behalf of the Trustee by manual signature, and such
certificate upon any Security shall be conclusive evidence, and the only
evidence, that such Security has been duly authenticated and delivered
hereunder.

         The Trustee may appoint an authenticating agent or agents reasonably
acceptable to the Company with respect to the Securities. Unless limited by the
terms of such appointment, an authenticating agent may authenticate Securities
whenever the Trustee may do so. Each reference in this Indenture to
authentication by the Trustee includes authentication by such agent.

          SECTION 2.5       REGISTRAR AND PAYING AGENT.

         The Company shall maintain an office or agency where Securities may be
presented for registration of transfer or for exchange (the "Registrar") and an
office or agency where Securities may be presented for payment (the "Paying
Agent"). The Registrar shall keep a register of the Securities (the "Register")
and of their transfer and exchange. The Company may appoint one or more
co-Registrars and one or more additional Paying Agents for the Securities. The
term "Paying Agent" includes any additional paying agent and the term
"Registrar" includes any additional registrar. The Company may change any Paying
Agent or Registrar without prior notice to any Holder.


                                       21


         The Company will cause each Paying Agent (other than the Trustee) to
execute and deliver to the Trustee an instrument in which such Paying Agent
shall agree with the Trustee, subject to the provisions of this Section, that
such Paying Agent will:

                       (1) hold all sums held by it for the payment of the
         principal of and premium, if any, or interest (including Liquidated
         Damages, if any) on Securities in trust for the benefit of the Persons
         entitled thereto until such sums shall be paid to such Persons or
         otherwise disposed of as provided in this Indenture;

                       (2) give the Trustee notice of any Default by the Company
         in the making of any payment of principal and premium, if any, or
         interest (including Liquidated Damages, if any); and

                       (3) at any time during the continuance of any such
         Default, upon the written request of the Trustee, forthwith pay to the
         Trustee all sums so held in trust by such Paying Agent.

         The Company shall give prompt written notice to the Trustee of the name
and address of any Agent who is not a party to this Indenture. If the Company
fails to appoint or maintain another entity as Registrar or Paying Agent, the
Trustee shall act as such. The Company or any Affiliate of the Company may act
as Paying Agent or Registrar; provided, however, that none of the Company, its
subsidiaries or the Affiliates of the foregoing shall act:

               (i) as Paying Agent in connection with redemptions, offers to
         purchase and discharges, as otherwise specified in this Indenture, and

               (ii) as Paying Agent or Registrar if a Default or Event of
         Default has occurred and is continuing.

         The Company hereby initially appoints the Trustee as Registrar and
Paying Agent for the Securities.

         SECTION 2.6       PAYING AGENT TO HOLD ASSETS IN TRUST.

         Not later than 11:00 a.m. (New York City time) on each due date of the
principal, premium, if any, and interest (including Liquidated Damages, if any)
on any Securities, the Company shall deposit with one or more Paying Agents
money in immediately available funds sufficient to pay such principal, premium,
if any, and interest (including Liquidated Damages, if any) so becoming due. The
Company at any time may require a Paying Agent to pay all money held by it to
the Trustee. Upon payment over to the Trustee, the Paying Agent (if other than
the Company) shall have no further liability for the money so paid over to the
Trustee.

         If the Company shall act as a Paying Agent, it shall, prior to or on
each due date of the principal of and premium, if any, or interest (including
Liquidated Damages, if any) on any of the Securities, segregate and hold in
trust for the benefit of the Holders a sum sufficient with monies held by all
other Paying Agents, to pay the principal and premium, if any, or interest
(including Liquidated Damages, if any) so becoming due until such sums shall be
paid to such


                                       22


Persons or otherwise disposed of as provided in this Indenture, and
shall promptly notify the Trustee of its action or failure to act.

         SECTION 2.7       GENERAL PROVISIONS RELATING TO TRANSFER AND EXCHANGE.

         The Securities are issuable only in registered form. A Holder may
transfer a Security only by written application to the Registrar stating the
name of the proposed transferee and otherwise complying with the terms of this
Indenture. No such transfer shall be effected until, and such transferee shall
succeed to the rights of a Holder only upon, final acceptance and registration
of the transfer by the Registrar in the Register. Furthermore, any Holder of a
Global Security shall, by acceptance of such Global Security, agree that
transfers of beneficial interests in such Global Security may be effected only
through a book-entry system maintained by the Holder of such Global Security (or
its agent) and that ownership of a beneficial interest in the Security shall be
required to be reflected in a book-entry. Notwithstanding the foregoing, in the
case of a Restricted Security, a beneficial interest in a Global Security being
transferred in reliance on an exemption from the registration requirements of
the Securities Act other than in accordance with Rule 144 and Rule 144A may only
be transferred for a Physical Security.

         When Securities are presented to the Registrar with a request to
register the transfer or to exchange them for an equal aggregate principal
amount of Securities of other authorized denominations, the Registrar shall
register the transfer or make the exchange as requested if its requirements for
such transactions are met (including that such Securities are duly endorsed or
accompanied by a written instrument of transfer duly executed by the Holder
thereof or by an attorney who is authorized in writing to act on behalf of the
Holder). Subject to Section 2.4 hereof, to permit registrations of transfers and
exchanges, the Company shall execute and the Trustee shall authenticate
Securities at the Registrar's request. No service charge shall be made for any
registration of transfer or exchange or redemption of the Securities, but the
Company may require payment of a sum sufficient to cover any transfer tax or
similar governmental charge payable in connection therewith (other than any such
transfer taxes or other similar governmental charge payable upon exchanges
pursuant to Section 2.14, 7.5 or 10.8 hereof).

         Neither the Company nor the Registrar shall be required to exchange or
register a transfer of any Securities:

                       (1) for a period of 15 Business Days prior to the day of
         any selection of Securities for redemption under Article 10 hereof;

                       (2) so selected for redemption or, if a portion of any
         Security is selected for redemption, such portion thereof selected for
         redemption; or

                       (3) surrendered for conversion or, if a portion of any
         Security is surrendered for conversion, such portion thereof
         surrendered for conversion.

         SECTION 2.8       BOOK-ENTRY PROVISIONS FOR THE GLOBAL SECURITIES.

         (a) The Global Securities initially shall:

               (i) be registered in the name of the Depositary (or a nominee
         thereof);


                                       23


               (ii) be delivered to the Trustee as custodian for such
         Depositary; and

               (iii) bear the Restricted Securities Legend as set forth in
         Section 2.3(a)(i) hereof.

         Members of, or participants in, the Depositary ("DTC Participants")
shall have no rights under this Indenture with respect to any Global Security
held on their behalf by the Depositary, or the Trustee as its custodian, or
under such Global Security, and the Depositary may be treated by the Company,
the Trustee and any agent of the Company or the Trustee as the absolute owner of
such Global Security for all purposes whatsoever. Notwithstanding the foregoing,
nothing contained herein shall prevent the Company, the Trustee or any agent of
the Company or Trustee from giving effect to any written certification, proxy or
other authorization furnished by the Depositary or impair, as between the
Depositary and the DTC Participants, the operation of customary practices
governing the exercise of the rights of a Holder of any Security.

         (b) The registered Holder of a Global Security may grant proxies and
otherwise authorize any Person, including DTC Participants and Persons that may
hold interests through DTC Participants, to take any action which a Holder is
entitled to take under this Indenture or the Securities.

         (c) A Global Security may not be transferred, in whole or in part, to
any Person other than the Depositary (or a nominee thereof), and no such
transfer to any such other Person may be registered. Beneficial interests in a
Global Security may be transferred in accordance with the rules and procedures
of the Depositary and the provisions of Section 2.9 hereof.

         (d) If at any time:

               (i) the Depositary notifies the Company in writing that it is no
         longer willing or able to continue to act as Depositary for the Global
         Securities, or the Depositary ceases to be a "clearing agency"
         registered under the Exchange Act and a successor depositary for the
         Global Securities is not appointed by the Company within 90 days of
         such notice or cessation;

               (ii) the Company, at its option, notifies the Trustee in writing
         that it elects to cause the issuance of the Securities in definitive
         form under this Indenture in exchange for all or any part of the
         Securities represented by a Global Security or Global Securities; or

               (iii) an Event of Default has occurred and is continuing and the
         Registrar has received a request from the Depositary for the issuance
         of Physical Securities in exchange for such Global Security or Global
         Securities,

the Depositary shall surrender such Global Security or Global Securities to the
Trustee for cancellation and the Company shall execute, and the Trustee, upon
receipt of an Officers' Certificate and Company Order for the authentication and
delivery of Securities, shall authenticate and deliver in exchange for such
Global Security or Global Securities, Physical Securities of like tenor as that
of the Global Securities in an aggregate principal amount equal to the aggregate
principal amount of such Global Security or Global Securities. Such Physical
Securities shall be registered in such names as the Depositary shall identify in
writing as


                                       24


the beneficial owners of the Securities represented by such Global
Security or Global Securities (or any nominee thereof).

         Notwithstanding the foregoing, in connection with any transfer of
beneficial interests in a Global Security to beneficial owners pursuant to
Section 2.8(d) hereof, the Registrar shall reflect on its books and records the
date and a decrease in the principal amount of such Global Security in an amount
equal to the principal amount of the beneficial interest in such Global Security
to be transferred.

         SECTION 2.9       SPECIAL TRANSFER PROVISIONS.

         Unless a Security is transferred after the time period referred to in
Rule 144(k) under the Securities Act or otherwise sold pursuant to a
registration statement that has been declared effective under the Securities Act
(and which continues to be effective at the time of such sale), the following
provisions shall apply.

         With respect to the registration of any proposed transfer of Securities
to a QIB:

               (i) If the Securities to be transferred consist of an interest in
         the Global Securities, the transfer of such interest may be effected
         only through the book-entry system maintained by the Depositary.

               (ii) If the Securities to be transferred consist of Physical
         Securities, the Registrar shall register the transfer if such transfer
         is being made by a proposed transferor who has checked the box provided
         for on the form of Security stating, or has otherwise advised the
         Company and the Registrar in writing, that the sale has been made in
         compliance with the provisions of Rule 144A to a transferee who has
         signed the certification provided for on the form of Security stating
         or has otherwise advised the Company and the Registrar in writing that:

               (A) it is purchasing the Securities for its own account or an
         account with respect to which it exercises sole investment discretion,
         in each case for investment and not with a view to distribution;

               (B) it and any such account is a QIB within the meaning of
         Rule 144A;

               (C) it is aware that the sale to it is being made in reliance on
         Rule 144A;

               (D) it acknowledges that it has received such information
         regarding the Company as it has requested pursuant to Rule 144A or has
         determined not to request such information; and

               (E) it is aware that the transferor is relying upon its foregoing
         representations in order to claim the exemption from registration
         provided by Rule 144A.


                                       25


         In addition, the Registrar shall reflect on its books and records the
date and an increase in the principal amount of the Global Securities in an
amount equal to the principal amount of the Physical Securities to be
transferred, and the Trustee shall cancel the Physical Securities so
transferred.

         By its acceptance of any Security bearing the Restricted Securities
Legend, each Holder of such a Security acknowledges the restrictions on transfer
of such Security set forth in this Indenture and agrees that it will transfer
such Security only as provided in this Indenture. The Registrar shall not
register a transfer of any Security unless such transfer complies with the
restrictions on transfer of such Security set forth in this Indenture. The
Registrar shall be entitled to receive and rely on written instructions from the
Company verifying that such transfer complies with such restrictions on
transfer. In connection with any transfer of Securities, each Holder agrees by
its acceptance of the Securities to furnish the Registrar or the Company such
certifications, legal opinions or other information as either of them may
reasonably require to confirm that such transfer is being made pursuant to an
exemption from, or a transaction not subject to, the registration requirements
of the Securities Act; provided that the Registrar shall not be required to
determine (but may rely on a determination made by the Company with respect to)
the sufficiency of any such certifications, legal opinions or other information.

         The Registrar shall retain copies of all letters, notices and other
written communications received pursuant to Section 2.8 hereof or this Section
2.9. The Company shall have the right to inspect and make copies of all such
letters, notices or other written communications at any reasonable time upon the
giving of reasonable written notice to the Registrar.

         SECTION 2.10      HOLDER LISTS.

         The Trustee shall preserve in as current a form as is reasonably
practicable the most recent list available to it of the names and addresses of
Holders and shall otherwise comply with Section 312(a) of the TIA. If the
Trustee is not the Registrar, the Company shall furnish to the Trustee prior to
or on each Interest Payment Date and at such other times as the Trustee may
request in writing a list in such form and as of such date as the Trustee may
reasonably require of the names and addresses of Holders relating to such
Interest Payment Date or request, as the case may be.

         SECTION 2.11      PERSONS DEEMED OWNERS.

         The Company, the Trustee and any agent of the Company or the Trustee
may treat the registered Holder of a Global Security as the absolute owner of
such Global Security for the purpose of receiving payment thereof or on account
thereof and for all other purposes whatsoever, whether or not such Security be
overdue, and notwithstanding any notice of ownership or writing thereon, or any
notice of previous loss or theft or other interest therein. The Company, the
Trustee and any agent of the Company or the Trustee may treat the Person in
whose name any Security is registered as the owner of such Security for the
purpose of receiving payment of principal of and premium, if any, and interest
(including Liquidated Damages, if any) on such Security and for all other
purposes whatsoever, whether or not such Security be overdue, and
notwithstanding any notice of ownership or writing thereon, or any notice of
previous loss or theft or other interest therein.


                                       26


         SECTION 2.12      MUTILATED, DESTROYED, LOST OR STOLEN SECURITIES.

         If any mutilated Security is surrendered to the Trustee, the Company
shall execute and the Trustee shall authenticate and deliver in exchange
therefor a new Security of like tenor and principal amount and bearing a number
not contemporaneously outstanding.

         If there is delivered to the Company and the Trustee

               (1) evidence to their satisfaction of the destruction, loss or
         theft of any Security, and

               (2) such security or indemnity as may be required by them to save
         each of them and any agent of either of them harmless, then, in the
         absence of notice to the Company or the Trustee that such Security has
         been acquired by a bona fide purchaser, the Company shall execute and,
         upon request, the Trustee shall authenticate and deliver, in lieu of
         any such destroyed, lost or stolen Security, a new Security of like
         tenor and principal amount and bearing a number not contemporaneously
         outstanding.

         In case any such mutilated, destroyed, lost or stolen Security has
become or is about to become due and payable, the Company in its discretion, but
subject to any conversion rights, may, instead of issuing a new Security, pay
such Security, upon satisfaction of the condition set forth in the preceding
paragraph.

         Upon the issuance of any new Security under this Section, the Company
may require the payment of a sum sufficient to cover any tax or other
governmental charge that may be imposed in relation thereto and any other
expenses (including the fees and expenses of the Trustee) connected therewith.

         Every new Security issued pursuant to this Section in lieu of any
destroyed, lost or stolen Security shall constitute an original additional
contractual obligation of the Company, whether or not the destroyed, lost or
stolen Security shall be at any time enforceable by anyone, and such new
Security shall be entitled to all the benefits of this Indenture equally and
proportionately with any and all other Securities duly issued hereunder.

         The provisions of this Section are exclusive and shall preclude (to the
extent lawful) all other rights and remedies with respect to the replacement or
payment of mutilated, destroyed, lost or stolen Securities.

         SECTION 2.13      TREASURY SECURITIES.

         In determining whether the Holders of the requisite principal amount of
Outstanding Securities are present at a meeting of Holders for quorum purposes
or have given any request, demand, authorization, direction, notice, consent or
waiver hereunder, Securities owned by the Company or any Affiliate of the
Company shall be disregarded and deemed not to be Outstanding, except that, in
determining whether the Trustee shall be protected in relying upon any such
determination as to the presence of a quorum or upon any such request, demand,
authorization, direction, notice, consent or waiver, only such Securities of
which the Trustee has received written notice and are so owned shall be so
disregarded.


                                       27


         SECTION 2.14      TEMPORARY SECURITIES.

         Pending the preparation of Securities in definitive form, the Company
may execute and the Trustee shall, upon written request of the Company,
authenticate and deliver temporary Securities (printed or lithographed).
Temporary Securities shall be issuable in any authorized denomination, and
substantially in the form of the Securities in definitive form but with such
omissions, insertions and variations as may be appropriate for temporary
Securities, all as may be determined by the Company. Every such temporary
Security shall be executed by the Company and authenticated by the Trustee upon
the same conditions and in substantially the same manner, and with the same
effect, as the Securities in definitive form. Without unreasonable delay, the
Company will execute and deliver to the Trustee Securities in definitive form
(other than in the case of Securities in global form) and thereupon any or all
temporary Securities (other than any such Securities in global form) may be
surrendered in exchange therefor, at each office or agency maintained by the
Company pursuant to Section 9.2 and the Trustee shall authenticate and deliver
in exchange for such temporary Securities an equal aggregate principal amount of
Securities in definitive form. Such exchange shall be made by the Company at its
own expense and without any charge therefor. Until so exchanged, the temporary
Securities shall in all respects be entitled to the same benefits and subject to
the same limitations under this Indenture as Securities in definitive form
authenticated and delivered hereunder.

         SECTION 2.15      CANCELLATION.

         All securities surrendered for payment, redemption, repurchase,
conversion, registration of transfer or exchange shall, if surrendered to any
Person other than the Trustee, be delivered to the Trustee. All Securities so
delivered shall be canceled promptly by the Trustee, and no Securities shall be
issued in lieu thereof except as expressly permitted by any of the provisions of
this Indenture. Upon written instructions of the Company, the Trustee shall
destroy canceled Securities and, after such destruction, shall deliver a
certificate of such destruction to the Company. If the Company shall acquire any
of the Securities, such acquisition shall not operate as a redemption or
satisfaction of the indebtedness represented by such Securities unless the same
are delivered to the Trustee for cancellation.

         SECTION 2.16      CUSIP NUMBERS.

         The Company in issuing the Securities may use "CUSIP" numbers (if then
generally in use), and the Trustee shall use CUSIP numbers in notices of
redemption or exchange as a convenience to Holders; provided that any such
notice shall state that no representation is made as to the correctness of such
numbers either as printed on the Securities or as contained in any such notice
and that reliance may be placed only on the other identification numbers printed
on the Securities, and any such redemption shall not be affected by any defect
in or omission of such numbers. The Company shall promptly notify the Trustee of
any change in the CUSIP numbers.


                                       28



         SECTION 2.17      DEFAULTED INTEREST.

         If the Company fails to make a payment of interest (including
Liquidated Damages, if any) on any Security when due and payable ("Defaulted
Interest"), it shall pay such Defaulted Interest plus (to the extent lawful) any
interest payable on the Defaulted Interest, in any lawful manner. It may elect
to pay such Defaulted Interest, plus any such interest payable on it, to the
Persons who are Holders of such Securities on which the interest is due on a
subsequent Special Record Date. The Company shall notify the Trustee in writing
of the amount of Defaulted Interest proposed to be paid on each such Security.
The Company shall fix any such Special Record Date and payment date for such
payment. At least 15 days before any such Special Record Date, the Company shall
mail to Holders affected thereby a notice that states the Special Record Date,
the Interest Payment Date, and amount of such interest (and such Liquidated
Damages, if any) to be paid.


                                       29


                                   ARTICLE 3

                           SATISFACTION AND DISCHARGE

         SECTION 3.1       SATISFACTION AND DISCHARGE OF INDENTURE.

         When:

               (1) The Company shall deliver to the trustee for cancellation all
         securities previously authenticated (other than any securities which
         have been destroyed, lost or stolen and in lieu of, or in substitution
         for which, other securities shall have been authenticated and
         delivered) and not previously canceled, or

               (2) (A) all the securities not previously canceled or delivered
         to the trustee for cancellation shall have become due and payable, or
         are by their terms to become due and payable within one year or are to
         be called for redemption within one year under arrangements
         satisfactory to the Trustee for the giving of notice of redemption,

                   (B) the Company shall deposit with the Trustee, in trust,
         cash in U.S. dollars and/or U.S. Government Obligations which through
         the payment of interest and principal in respect thereof, in accordance
         with their terms, will provide (and without reinvestment and assuming
         no tax liability will be imposed on such Trustee), not later than one
         day before the due date of any payment of money, an amount in cash,
         sufficient, in the opinion of a nationally recognized firm of
         independent public accountants expressed in a written certification
         thereof delivered to the Trustee, to pay principal of, premium, if any,
         or interest (including Liquidated Damages, if any) on all of the
         Securities (other than any Securities which shall have been mutilated,
         destroyed, lost or stolen and in lieu of or in substitution for which
         other Securities shall have been authenticated and delivered) not
         previously canceled or delivered to the Trustee for cancellation, on
         the dates such payments of principal, premium, if any, or interest
         (including Liquidated Damages, if any) are due to such date of
         maturity or redemption, as the case may be, and

                   (C) the Company shall have delivered to the Trustee an
         Officers' Certificate and an Opinion of Counsel to the effect that (x)
         the Company has received from, or there has been published by, the
         Internal Revenue Service a ruling or (y) since the date of execution of
         this Indenture, there has been a change in the applicable federal
         income tax law, in the case of either clause (x) or (y) to the effect
         that, and based thereon such Opinion of Counsel shall confirm that, the
         Holders will not recognize income, gain or loss for federal income tax
         purposes as a result of such deposit and discharge and will be subject
         to federal income tax on the same amount and in the same manner and at
         the same times as would have been the case if such deposit and
         discharge had not occurred, and

if, in the case of either clause (1) or (2), the Company shall also pay or cause
to be paid all other sums payable hereunder by the Company, then this Indenture
shall cease to be of further effect (except as to:


                                       30



                (i)   remaining rights of registration of transfer, substitution
          and exchange and conversion of Securities,

               (ii)   rights hereunder of Holders to receive payments of
         principal of and premium, if any, and interest (including Liquidated
         Damages, if any) on, the Securities and the other rights, duties and
         obligations of Holders, as beneficiaries hereof with respect to the
         amounts, if any, so deposited with the Trustee, and

                (iii) the rights, obligations and immunities of the Trustee
          hereunder),


and the Trustee, on demand of the Company accompanied by an Officers'
Certificate and an Opinion of Counsel and at the cost and expense of the
Company, shall execute proper instruments acknowledging satisfaction of and
discharging this Indenture; provided, however, the Company shall reimburse
the Trustee for all amounts due the Trustee under Section 5.8 hereof and for
any costs or expenses thereafter reasonably and properly incurred by the
Trustee and to compensate the Trustee for any services thereafter reasonably
and properly rendered by the Trustee in connection with this Indenture or the
Securities.

         SECTION 3.2   DEPOSITED MONIES TO BE HELD IN TRUST.

         Subject to Section 3.3 hereof, all monies deposited with the Trustee
pursuant to Section 3.1 hereof shall be held in trust and applied by it to the
payment, notwithstanding the provisions of Article 13 hereof, either directly or
through any Paying Agent (including the Company if acting as its own Paying
Agent), to the Holders of the particular Securities for the payment or
redemption of which such monies have been deposited with the Trustee, of all
sums due and to become due thereon for principal, premium, if any, and interest
(including Liquidated Damages, if any). All monies deposited with the Trustee
pursuant to Section 3.1 hereof (and held by it or any Paying Agent) for the
payment of Securities subsequently converted shall be returned to the Company
upon request of the Company.

         SECTION 3.3   RETURN OF UNCLAIMED MONIES.

         The Trustee and the Paying Agent shall pay to the Company any money
held by them for the payment of principal or premium, if any, or interest
(including Liquidated Damages, if any) that remains unclaimed for two years
after the date upon which such payment shall have become due. After payment to
the Company, Holders entitled to the money must look to the Company for payment
as general creditors unless an applicable abandoned property law designates
another Person, and all liability of the Trustee and such Paying Agent with
respect to such money shall cease.


                                      31



                                   ARTICLE 4

                             DEFAULTS AND REMEDIES

         SECTION 4.1   EVENTS OF DEFAULT.

         An "Event of Default" with respect to the Securities occurs when any of
the following occurs (whatever the reason for such Event of Default and whether
it shall be occasioned by the provisions of Article 13 hereof or be voluntary or
involuntary or be effected by operation of law or pursuant to any judgment,
decree or order of any court or any order, rule or regulation of any
administrative or governmental body):

         (a) the Company defaults in the payment of the principal of or
premium, if any, on any of the Securities when it becomes due and payable at
Maturity, upon redemption or exercise of a Repurchase Right or otherwise,
whether or not such payment is prohibited by Article 13 hereof; or

         (b) the Company defaults in the payment of interest (including
Liquidated Damages, if any) on any of the Securities when it becomes due and
payable and such default continues for a period of 30 days, whether or not
such payment is prohibited by Article 13 hereof; or

         (c) the Company fails to perform or observe any other term, covenant
or agreement contained in the Securities or this Indenture and the default
continues for a period of 60 days after written notice of such failure,
requiring the Company to remedy the same, shall have been given to the
Company by the Trustee or to the Company and the Trustee by the Holders of at
least 25% in aggregate principal amount of the Outstanding Securities; or

         (d) (i) the Company fails to make any payment by the end of the
applicable grace period, if any, after the maturity of any Indebtedness for
borrowed money in an amount in excess of $5,000,000 (provided that such
failure shall not constitute an Event of Default if (1) the Company
determines, in good faith, that a lessor under a lease described in clause
(3)(a) of the definition of Indebtedness breached a covenant under the lease
and the Company has given notice of the breach to the lessor and the Trustee
and (2) as a result of the breach, the Company withholds payment under the
lease) (a "Default Exception"), or (ii) there is an acceleration of any
Indebtedness for borrowed money in an amount in excess of $5,000,000 because
of a default with respect to such Indebtedness (other than a Default
Exception) without such Indebtedness having been discharged or such
acceleration having been cured, waived, rescinded or annulled, in the case of
either (i) or (ii) above, for a period of 30 days after written notice to the
Company by the Trustee or to the Company and the Trustee by Holders of at
least 25% in aggregate principal amount of the Outstanding Securities; or

         (e) the entry by a court having jurisdiction in the premises of (i)
a decree or order for relief in respect of the Company in an involuntary case
or proceeding under any applicable U.S. federal or state bankruptcy,
insolvency, reorganization or other similar law or (ii) a decree or order
adjudging the Company a bankrupt or insolvent, or approving as properly filed
a petition seeking reorganization, arrangement, adjustment or composition of
or in respect of the Company under any applicable U.S. federal or state law,
or appointing a custodian, receiver, liquidator,


                                      32



assignee, trustee, sequestrator or other similar official of the Company or
of any substantial part of its property, or ordering the winding up or
liquidation of its affairs, and the continuance of any such decree or order
for relief or any such other decree or order unstayed and in effect for a
period of 60 consecutive days; or

         (f) the commencement by the Company of a voluntary case or
proceeding under any applicable U.S. federal or state bankruptcy, insolvency,
reorganization or other similar law or of any other case or proceeding to be
adjudicated a bankrupt or insolvent, or the consent by the Company to the
entry of a decree or order for relief in respect of the Company in an
involuntary case or proceeding under any applicable U.S. federal or state
bankruptcy, insolvency, reorganization or other similar law or to the
commencement of any bankruptcy or insolvency case or proceeding against the
Company, or the filing by the Company of a petition or answer or consent
seeking reorganization or relief under any applicable U.S. federal or state
law, or the consent by the Company to the filing of such petition or to the
appointment of or the taking possession by a custodian, receiver, liquidator,
assignee, trustee, sequestrator or other similar official of the Company or
of any substantial part of its property, or the making by the Company of an
assignment for the benefit of creditors, or the admission by the Company in
writing of its inability to pay its debts generally as they become due, or
the taking of corporate action by the Company expressly in furtherance of any
such action.

         SECTION 4.2   ACCELERATION OF MATURITY; RESCISSION AND ANNULMENT.

         If an Event of Default with respect to Outstanding Securities (other
than an Event of Default specified in Section 4.1(e) or 4.1(f) hereof) occurs
and is continuing, the Trustee or the Holders of at least 25% in aggregate
principal amount of the Outstanding Securities, by written notice to the
Company, may declare due and payable 100% of the principal amount of all
Outstanding Securities plus any accrued and unpaid interest to the date of
payment. Upon a declaration of acceleration, such principal and accrued and
unpaid interest to the date of payment shall be immediately due and payable.

         If an Event of Default specified in Section 4.1(e) or 4.1(f) hereof
occurs, all unpaid principal and accrued and unpaid interest (including
Liquidated Damages, if any) on the Outstanding Securities shall become and be
immediately due and payable, without any declaration or other act on the part
of the Trustee or any Holder.

         Any payments by the Company on the Securities following any such
acceleration will be subject to the subordination provisions of Article 13 to
the extent provided therein.

         The Holders of a majority in aggregate principal amount of the
Outstanding Securities by written notice to the Trustee and the Company may
rescind and annul an acceleration and waive such defaults and their
consequences if:

                (1) all existing Events of Default, other than the nonpayment of
          principal of or interest on the Securities which have become due
          solely because of the acceleration, have been remedied, cured or
          waived,

                (2) the rescission would not conflict with any judgment or
          decree of a court of competent jurisdiction, and


                                      33



                (3) the principal of any Securities which has become due
          otherwise than by such declaration of acceleration and any interest
          thereon at the rate or rates prescribed therefor has been deposited
          with the Trustee;

provided, however, that in the event such declaration of acceleration has
been made based on the existence of an Event of Default under Section 4.1(d)
hereof and such Event of Default has been remedied, cured or waived in
accordance with Section 4.1(d) hereof, then, without any further action by
the Holders, such declaration of acceleration shall be rescinded
automatically and the consequences of such declaration shall be annulled. No
such rescission or annulment shall affect any subsequent Default or impair
any right consequent thereon.

         SECTION 4.3   OTHER REMEDIES.

         If an Event of Default with respect to Outstanding Securities occurs
and is continuing, the Trustee may pursue any available remedy by proceeding
at law or in equity to collect the payment of principal of or interest on the
Securities or to enforce the performance of any provision of the Securities.

         The Trustee may maintain a proceeding in which it may prosecute and
enforce all rights of action and claims under this Indenture or the
Securities, even if it does not possess any of the Securities or does not
produce any of them in the proceeding.

         SECTION 4.4   WAIVER OF PAST DEFAULTS.

         The Holders, either (a) through the written consent of not less than
a majority in aggregate principal amount of the Outstanding Securities, or
(b) by the adoption of a resolution, at a meeting of Holders of the
Outstanding Securities at which a quorum is present, by the Holders of at
least a majority in aggregate principal amount of the Outstanding Securities
represented at such meeting, may, on behalf of the Holders of all of the
Securities, waive an existing Default or Event of Default, except a Default
or Event of Default:

                   (1) in the payment of the principal of or premium, if any,
         or interest (including Liquidated Damages, if any) on any Security
         (provided, however, that subject to Section 4.7 hereof, the Holders
         of a majority in aggregate principal amount of the Outstanding
         Securities may rescind an acceleration and its consequences,
         including any related payment default that resulted from such
         acceleration); or

                   (2) in respect of a covenant or provision hereof which,
         under Section 7.2 hereof, cannot be modified or amended without the
         consent of the Holders of each Outstanding Security affected.

         Upon any such waiver, such Default shall cease to exist, and any Event
of Default arising therefrom shall be deemed to have been cured, for every
purpose of this Indenture; provided, however, that no such waiver shall extend
to any subsequent or other Default or impair any right consequent thereon.


                                      34



         SECTION 4.5   CONTROL BY MAJORITY.

         The Holders of a majority in aggregate principal amount of the
Outstanding Securities (or such lesser amount as shall have acted as a meeting
pursuant to the provisions of this Indenture) shall have the right to direct the
time, method and place of conducting any proceeding for any remedy available to
the Trustee or exercising any trust or power conferred on the Trustee. However,
the Trustee may refuse to follow any direction that:

                (1) conflicts with any law or with this Indenture;

                (2) the Trustee determines may be unduly prejudicial to the
          rights of the Holders not joining therein, or

                (3) may expose the Trustee to personal liability.

The Trustee may take any other action deemed proper by the Trustee which is not
inconsistent with such direction.

          SECTION 4.6   LIMITATION ON SUIT.

No Holder of any Security shall have any right to pursue any remedy with respect
to this indenture or the Securities (including, instituting any proceeding,
judicial or otherwise, with respect to this Indenture or for the appointment of
a receiver or trustee) unless:

                (1) such Holder has previously given written notice to the
          Trustee of an Event of Default that is continuing;

                (2) the Holders of at least 25% in aggregate principal amount of
          the Outstanding Securities shall have made written request to the
          Trustee to pursue the remedy;

                (3) such Holder or Holders have offered to the Trustee indemnity
          satisfactory to it against any costs, expenses and liabilities
          incurred in complying with such request;

                (4) the Trustee has failed to comply with the request for 60
          days after its receipt of such notice, request and offer of indemnity;
          and

                (5) during such 60-day period, no direction inconsistent with
          such written request has been given to the Trustee by the Holders of a
          majority in aggregate principal amount of the Outstanding Securities
          (or such amount as shall have acted at a meeting pursuant to the
          provisions of this Indenture);

provided, however, that no one or more of such Holders may use this Indenture to
prejudice the rights of another Holder or to obtain preference or priority over
another Holder.


                                      35



         SECTION 4.7  UNCONDITIONAL RIGHTS OF HOLDERS TO RECEIVE PAYMENT AND TO
                      CONVERT.

         Notwithstanding any other provision in this Indenture, the Holder of
any Security shall have the right, which is absolute and unconditional, to
receive payment of the principal of and premium, if any, and interest (including
Liquidated Damages, if any) on such Security on the Stated Maturity expressed in
such Security (or, in the case of redemption, on the Redemption Date, or in the
case of the exercise of a Repurchase Right, on the Repurchase Date) and to
convert such Security in accordance with Article 12, and to bring for the
enforcement of any such payment on or after such respective dates and right to
convert, and such rights shall not be impaired or affected without the consent
of such Holder.

         SECTION 4.8  COLLECTION OF INDEBTEDNESS AND SUITS FOR ENFORCEMENT BY
                      THE TRUSTEE.

         The Company covenants that if:

                     (1) a Default or Event of Default is made in the payment
         of any interest (including Liquidated Damages, if any) on any
         Security when such interest (including Liquidated Damages, if any)
         becomes due and payable and such Default or Event of Default
         continues for a period of 30 days, or

                     (2) a Default or Event of Default is made in the payment
         of the principal of or premium, if any, on any Security at the
         Maturity thereof,

the Company will, upon demand of the Trustee, pay to it, for the benefit of the
Holders of such Securities, the whole amount then due and payable (as expressed
therein or as a result of any acceleration effected pursuant to Section 4.2
hereof) on such Securities for principal and premium, if any, and interest
(including Liquidated Damages, if any) and, to the extent that payment of such
interest shall be legally enforceable, interest on any overdue principal and
premium, if any, and on any overdue interest (including Liquidated Damages, if
any), calculated using the Interest Rate, and, in addition thereto, such further
amount as shall be sufficient to cover the costs and expenses of collection,
including the reasonable compensation, expenses, disbursements and advances of
the Trustee, its agents and counsel.

         If the Company fails to pay such amounts forthwith upon such demand,
the Trustee, in its own name and as trustee of an express trust, may institute a
judicial proceeding for the collection of the sums so due and unpaid, may
prosecute such proceeding to judgment or final decree and may enforce the same
against the Company and collect the moneys adjudged or decreed to be payable in
the manner provided by law out of the property of the Company, wherever
situated.

         If an Event of Default occurs and is continuing, the Trustee may in its
discretion proceed to protect and enforce its rights and the rights of the
Holders of Securities by such appropriate judicial proceedings as the Trustee
shall deem most effectual to protect and enforce any such rights, whether for
the specific enforcement of any covenant or agreement in this Indenture or in
aid of the exercise of any power granted herein, or to enforce any other proper
remedy.


                                     36



         SECTION 4.9  TRUSTEE MAY FILE PROOFS OF CLAIM.

         In case of the pendency of any receivership, insolvency, liquidation,
bankruptcy, reorganization, arrangement, adjustment, composition or other
judicial proceeding relative to the Company or the property of the Company or
its creditors, the Trustee (irrespective of whether the principal of the
Securities shall then be due and payable as therein expressed or by declaration
or otherwise and irrespective of whether the Trustee shall have made any demand
on the Company for the payment of overdue principal or interest (including
Liquidated Damages, if any)) shall be entitled and empowered, by intervention in
such proceeding or otherwise,

                (1) to file and prove a claim for the whole amount of principal
          and premium, if any, and interest (including Liquidated Damages, if
          any) owing and unpaid in respect of the Securities and to file such
          other papers or documents as may be necessary or advisable in order to
          have the claims of the Trustee (including any claim for the reasonable
          compensation, expenses, disbursements and advances of the Trustee, its
          agents and counsel) and of the Holders of Securities allowed in such
          judicial proceeding, and

                (2) to collect and receive any moneys or other property payable
          or deliverable on any such claim and to distribute the same;

and any custodian, receiver, assignee, trustee, liquidator, sequestrator or
other similar official in any such judicial proceedings is hereby authorized by
each Holder of Securities to make such payments to the Trustee and, in the event
that the Trustee shall consent to the making of such payments directly to the
Holders of Securities, to pay to the Trustee any amount due to it for the
reasonable compensation, expenses, disbursements and advances of the Trustee,
its agents and counsel and any other amounts due the Trustee under Section 5.8.

         Nothing contained herein shall be deemed to authorize the Trustee to
authorize or consent to or accept, or adopt on behalf of any Holder of a
Security, any plan of reorganization, arrangement, adjustment or composition
affecting the Securities or the rights of any Holder thereof or to authorize the
Trustee to vote in respect of the claim of any Holder of a Security in any such
proceeding.

         SECTION 4.10  RESTORATION OF RIGHTS AND REMEDIES.

         If the Trustee or any Holder of a Security has instituted any
proceeding to enforce any right or remedy under this Indenture and such
proceeding has been discontinued or abandoned for any reason, or has been
determined adversely to the Trustee or to such Holder, then and in every such
case, subject to any determination in such proceeding, the Company, the Trustee
and the Holders of Securities shall be restored severally and respectively to
their former positions hereunder and thereafter all rights and remedies of the
Trustee and the Holders shall continue as though no such proceeding had been
instituted.

         SECTION 4.11  RIGHTS AND REMEDIES CUMULATIVE.

         Except as otherwise provided with respect to the replacement or payment
of mutilated, destroyed, lost or stolen Securities in the last paragraph of
Section 2.12, no right or remedy


                                      37



conferred in this Indenture upon or reserved to the Trustee or to the Holders
of Securities is intended to be exclusive of any other right or remedy, and
every right and remedy shall, to the extent permitted by law, be cumulative
and in addition to every other right and remedy given hereunder or hereafter
existing at law or in equity or otherwise. The assertion or employment of any
right or remedy hereunder, or otherwise, shall not prevent the concurrent
assertion or employment of any other appropriate right or remedy.

         SECTION 4.12  DELAY OR OMISSION NOT WAIVER.

         No delay or omission of the Trustee or of any Holder of any Security to
exercise any right or remedy accruing upon any Event of Default shall impair any
such right or remedy or constitute a waiver of any such Event of Default or any
acquiescence therein. Every right and remedy given by this Article or by law to
the Trustee or to the Holders of Securities may be exercised from time to time,
and as often as may be deemed expedient, by the Trustee or by the Holders of
Securities, as the case may be.

         SECTION 4.13  APPLICATION OF MONEY COLLECTED.

         Subject to Article 13, any money collected by the Trustee pursuant to
this Article shall be applied in the following order, at the date or dates fixed
by the Trustee and, in case of the distribution of such money on account of
principal or premium, if any, or interest (including Liquidated Damages, if
any), upon presentation of the Securities and the notation thereon of the
payment if only partially paid and upon surrender thereof if fully paid:

                  FIRST:  To the payment of all amounts due the Trustee;

                  SECOND: To the payment of the amounts then due and unpaid for
         principal of and premium, if any, and interest (including Liquidated
         Damages, if any) on the Securities and coupons in respect of which or
         for the benefit of which such money has been collected, ratably,
         without preference or priority of any kind, according to the amounts
         due and payable on such Securities for principal and premium, if any,
         and interest (including Liquidated Damages, if any), respectively; and

                  THIRD:  Any remaining amounts shall be repaid to the Company.

         SECTION 4.14  UNDERTAKING FOR COSTS.

         All parties to this Indenture agree, and each Holder of any Security by
such Holder's acceptance thereof shall be deemed to have agreed, that any court
may in its discretion require, in any suit for the enforcement of any right or
remedy under this Indenture, or in any suit against the Trustee for any action
taken, suffered or omitted by it as Trustee, the filing by any party litigant in
such suit of an undertaking to pay the costs of such suit, and that such court
may in its discretion assess reasonable costs, including reasonable attorneys'
fees, against any party litigant in such suit, having due regard to the merits
and good faith of the claims or defenses made by such party litigant; but the
provisions of this Section shall not apply to any suit instituted by the
Company, to any suit instituted by the Trustee, to any suit instituted by any
Holder, or group of Holders, holding in the aggregate more than 10% in aggregate
principal amount of the Outstanding Securities, or to any suit instituted by any
Holder of any Security for the


                                     38



enforcement of the payment of the principal of or premium, if any, or
interest (including Liquidated Damages, if any) on any Security on or after
the Stated Maturity expressed in such Security (or, in the case of redemption
or exercise of a Repurchase Right, on or after the Redemption Date) or for
the enforcement of the right to convert any Security in accordance with
Article 12.

         SECTION 4.15  WAIVER OF STAY OR EXTENSION LAWS.

         The Company covenants (to the extent that it may lawfully do so) that
it will not at any time insist upon, or plead, or in any manner whatsoever claim
to take the benefit or advantage of, any stay or extension law wherever enacted,
now or at any time hereafter in force, which may affect the covenants or the
performance of this Indenture; and the Company (to the extent that it may
lawfully do so) hereby expressly waives all benefit or advantage of any such law
and covenants that it will not hinder, delay or impede the execution of any
power herein granted to the Trustee, but will suffer and permit the execution of
every such power as though no such law had been enacted.


                                      39



                                  ARTICLE 5

                                 THE TRUSTEE

         SECTION 5.1  CERTAIN DUTIES AND RESPONSIBILITIES.

         (a)  Except during the continuance of an Event of Default,

                   (1) The Trustee undertakes to perform such duties and only
         such duties as are specifically set forth in this Indenture or the
         TIA, and no implied covenants or obligations shall be read into this
         Indenture against the Trustee; and

                   (2) In the absence of bad faith on its part, the Trustee
         may conclusively rely, as to the truth of the statements and the
         correctness of the opinions expressed therein, upon certificates or
         opinions furnished to the Trustee and conforming to the requirements
         of this Indenture; provided, however, that in the case of any such
         certificates or opinions which by any provision hereof are
         specifically required to be furnished to the Trustee, the Trustee
         shall examine the certificates or opinions to determine whether or
         not, on their face, they conform to the requirements to this
         Indenture (but need not investigate or confirm the accuracy of any
         facts stated therein).

         (b) In case an Event of Default actually known to a Responsible
Officer of the Trustee has occurred and is continuing, the Trustee shall
exercise such of the rights and powers vested in it by this Indenture, and
use the same degree of care and skill in their exercise, as a prudent person
would exercise or use under the circumstances in the conduct of such person's
own affairs.

         (c) No provision of this Indenture shall be construed to relieve the
Trustee from liability for its own negligent action, its own negligent
failure to act, or its own willful misconduct, except that:

                (1) This paragraph (c) shall not be construed to limit the
          effect of paragraph (a) of this Section 5.1;

                (2) The Trustee shall not be liable for any error of judgment
          made in good faith by a Responsible Officer, unless it shall be proved
          that the Trustee was negligent in ascertaining the pertinent facts;
          and

                (3) The Trustee shall not be liable with respect to any action
          taken or omitted to be taken by it in good faith in accordance with a
          direction received by it of the Holders of a majority in principal
          amount of the Outstanding Securities (or such lesser amount as shall
          have acted at a meeting pursuant to the provisions of this Indenture)
          relating to the time, method and place of conducting any proceeding
          for any remedy available to the Trustee, or exercising any trust or
          power conferred upon the Trustee, under this Indenture.


                                      40


         (d) Whether or not herein expressly so provided, every provision of
this Indenture relating to the conduct or affecting the liability of or
affording protection to the Trustee shall be subject to the provisions of
this Section 5.1.

         (e) No provision of this Indenture shall require the Trustee to
expend or risk its own funds or otherwise incur any liability in the
performance of any of its duties hereunder, or in the exercise of any of its
rights or powers. The Trustee may refuse to perform any duty or exercise any
right or power unless it receives indemnity reasonably satisfactory to it
against any loss, liability, cost or expense (including, without limitation,
reasonable fees of counsel).

         (f) The Trustee shall not be obligated to pay interest on any money
or other assets received by it unless otherwise agreed in writing with the
Company. Assets held in trust by the Trustee need not be segregated from
other funds except to the extent required by law.

         (g) The Trustee shall not be bound to make any investigation into
the facts or matters stated in any resolution, certificate, statement,
instrument, opinion, report, notice, request, direction, consent, order,
bond, debenture, note, coupon, other evidence of indebtedness or other paper
or document, but the Trustee, in its discretion, may make such further
inquiry or investigation into such facts or matters as it may see fit, and,
if the Trustee shall determine to make such further inquiry or investigation,
it shall be entitled to examine the books, records and premises of the
Company, personally or by agent or attorney.

         (h) The Trustee shall not be deemed to have notice or actual
knowledge of any Event of Default or a Registration Default (as such term is
defined in Section 3(a) of the Registration Rights Agreement) or the
obligation of the Company to pay Liquidated Damages unless a Responsible
Officer of the Trustee has actual knowledge thereof or unless written notice
of any event which is in fact a Default is received by the Trustee pursuant
to Section 14.2 hereof, and such notice references the Securities and this
Indenture.

         (i) The rights, privileges, protections, immunities and benefits
given to the Trustee hereunder, including, without limitation, its right to
be indemnified, are extended to, and shall be enforceable by, the Trustee in
each of its capacities hereunder, and each Paying Agent, authenticating
agent, Conversion Agent or Registrar acting hereunder.

         SECTION 5.2  CERTAIN RIGHTS OF TRUSTEE.

         Subject to the provisions of Section 5.1 hereof and subject to Section
315(a) through (d) of the TIA:

                   (1) The Trustee may rely on any document reasonably
         believed by it to be genuine and to have been signed or presented by
         the proper person. The Trustee need not investigate any fact or
         matter stated in the document.

                   (2) Before the Trustee acts or refrains from acting, it
         may require an Officers' Certificate or an Opinion of Counsel, or
         both. The Trustee shall not be liable for any action it takes or
         omits to take in good faith in reliance on the Officers' Certificate
         or Opinion of Counsel.


                                      41



                   (3) The Trustee may act through attorneys and agents and
         shall not be responsible for the misconduct or negligence of any
         attorney or agent appointed with due care.

                   (4) The Trustee shall not be liable for any action taken
         or omitted to be taken by it in good faith which it believed to be
         authorized or within the discretion or rights or powers conferred
         upon it by this Indenture, unless the Trustee's conduct constitutes
         negligence.

                   (5) The Trustee may consult with counsel of its selection
         and the written advice of such counsel as to matters of law shall be
         full and complete authorization and protection in respect of any
         action taken, omitted or suffered by it hereunder in good faith and
         in accordance with the advice or opinion of such counsel; provided,
         however, that the provisions shall not protect the Trustee from
         liability for its own gross negligence or willful misconduct.

                   (6) Unless otherwise specifically provided in this
         Indenture, any demand, request, direction or notice from the Company
         shall be sufficient if signed by an Officer of the Company.

                   (7) The permissive rights of the Trustee to do things
         enumerated in this Indenture shall not be construed as a duty unless
         so specified herein.

         SECTION 5.3  INDIVIDUAL RIGHTS OF TRUSTEE.

         The Trustee in its individual or any other capacity may become the
owner or pledgee of Securities and may otherwise deal with the Company or any
Affiliate of the Company with the same rights it would have if it were not
Trustee. However, in the event that the Trustee acquires any conflicting
interest (as such term is defined in Section 310(b) of the TIA), it must
eliminate such conflict within 90 days, apply to the SEC for permission to
continue as trustee (to the extent permitted under Section 310(b) of the TIA) or
resign. Any agent may do the same with like rights and duties. The Trustee is
also subject to Sections 5.11 and 5.12 hereof.

         Subject to the limitations imposed by the Trustee Indenture Act,
nothing in this Indenture shall prohibit the Trustee from becoming and acting as
trustee under other indentures under which other securities, or certificates of
interest of participation in other securities, of the Company are outstanding in
the same manner as if it were not Trustee hereunder.

         SECTION 5.4  MONEY HELD IN TRUST.

         Money held by the Trustee in trust hereunder need not be segregated
from other funds except to the extent required by law. The Trustee shall be
under no liability for interest on any money received by it hereunder except as
otherwise expressly agreed with the Company.

         SECTION 5.5  TRUSTEE'S DISCLAIMER.

         The recitals contained herein and in the Securities (except for those
in the certificate of authentication) shall be taken as the statements of the
Company, and the Trustee assumes no


                                     42



responsibility for their correctness. The Trustee makes no representations as
to the validity, sufficiency or priority of this Indenture or of the
Securities. The Trustee shall not be accountable for the use or application
by the Company of Securities or the proceeds thereof.

         SECTION 5.6  NOTICE OF DEFAULTS.

         Within 90 days after the occurrence of any Default or Event of
Default hereunder of which the Trustee has received written notice, the
Trustee shall give notice to Holders pursuant to Section 14.2 hereof, unless
such Default or Event of Default shall have been cured or waived; provided,
however, that, except in the case of a Default or Event of Default in the
payment of the principal of or premium, if any, or interest (including
Liquidated Damages, if any), or in the payment of any redemption or
repurchase obligation on any Security, the Trustee shall be protected in
withholding such notice if and so long as Responsible Officers of the Trustee
in good faith determine that the withholding of such notice is in the
interest of the Holders.

         SECTION 5.7  REPORTS BY TRUSTEE TO HOLDERS.

         The Trustee shall transmit to Holders such reports concerning the
Trustee and its actions under this Indenture as may be required by Section
313 of the TIA at the times and in the manner provided by the TIA.

         A copy of each report at the time of its mailing to Holders shall be
filed with the SEC, if required, and each stock exchange, if any, on which
the Securities are listed. The Company shall promptly notify the Trustee when
the Securities become listed on any stock exchange.

         SECTION 5.8  COMPENSATION AND INDEMNIFICATION.

         The Company covenants and agrees to pay to the Trustee from time to
time, and the Trustee shall be entitled to, reasonable compensation (which
shall not be limited by any provision of law in regard to the compensation of
a trustee of an express trust) and the Company covenants and agrees to pay or
reimburse the Trustee upon its request for all reasonable expenses,
disbursements and advances incurred or made by or on behalf of it in
accordance with any of the provisions of this Indenture (including the
reasonable compensation and the expenses and disbursements of its counsel and
of all agents and other persons not regularly in its employ), except to the
extent that any such expense, disbursement or advance is due to its
negligence or bad faith. When the Trustee incurs expenses or renders services
in connection with an Event of Default specified in Section 4.1 hereof, the
expenses (including the reasonable charges and expenses of its counsel) and
the compensation for the services are intended to constitute expenses of
administration under any bankruptcy law. The Company also covenants to
indemnify the Trustee and its officers, directors, employees and agents for,
and to hold such Persons harmless against, any loss, liability or expense
incurred by them, arising out of or in connection with the acceptance or
administration of this Indenture or the trusts hereunder or the performance
of their duties hereunder, including the costs and expenses of defending
themselves against or investigating any claim of liability in the premises,
except to the extent that any such loss, liability or expense was due to the
negligence or willful misconduct of such Persons. The obligations of the
Company under this Section 5.8 to compensate and indemnify the Trustee and
its officers, directors, employees and agents and to pay or reimburse such
Persons for expenses,


                                     43



disbursements and advances shall constitute additional indebtedness hereunder
and shall survive the satisfaction and discharge of this Indenture or the
earlier resignation or removal of the Trustee. Such additional indebtedness
shall be a senior claim to that of the Securities upon all property and funds
held or collected by the Trustee as such, except funds held in trust for the
benefit of the Holders of particular Securities, and the Securities are
hereby subordinated to such senior claim. "Trustee" for purposes of this
Section 5.8 shall include any predecessor Trustee, but the negligence or
willful misconduct of any Trustee shall not affect the indemnification of any
other Trustee.

         SECTION 5.9  REPLACEMENT OF TRUSTEE.

         A resignation or removal of the Trustee and appointment of a
successor Trustee shall become effective only upon the successor Trustee's
acceptance of appointment as provided in this Section 5.9.

         The Trustee may resign and be discharged from the trust hereby
created by so notifying the Company in writing. The Holders of at least a
majority in aggregate principal amount of Outstanding Securities may remove
the Trustee by so notifying the Trustee and the Company in writing. The
Company must remove the Trustee if:

                  (i) the Trustee fails to comply with Section 5.11 hereof or
          Section 310 of the TIA;

                 (ii) the Trustee becomes incapable of acting.

                (iii) the Trustee is adjudged a bankrupt or an insolvent or an
          order for relief is entered with respect to the Trustee under any
          Bankruptcy Law; or

                 (iv) a Custodian or public officer takes charge of the Trustee
          or its property.

         If the Trustee resigns or is removed or if a vacancy exists in the
office of the Trustee for any reason, the Company shall promptly appoint a
successor Trustee. The Trustee shall be entitled to payment of its fees and
reimbursement of its expenses while acting as Trustee. Within one year after the
successor Trustee takes office, the Holders of at least a majority in aggregate
principal amount of Outstanding Securities may appoint a successor Trustee to
replace the successor Trustee appointed by the Company.

         In the event the Trustee fails to comply with Section 5.11 hereof, (a)
the Company may remove the Trustee or (b) any Holder may, on behalf of himself
or herself and all others similarly situated, petition any court of competent
jurisdiction for the removal of the Trustee and the appointment of a successor
Trustee.

         If an instrument of acceptance by a successor Trustee shall not have
been delivered to the Trustee within 30 days after the giving of such notice of
resignation or removal, the resigning or removed Trustee, as the case may be,
may petition, at the expense of the Company, any court of competent jurisdiction
for the appointment of a successor Trustee.


                                      44



         A successor Trustee shall deliver a written acceptance of its
appointment to the retiring Trustee and to the Company. Thereupon the
resignation or removal of the retiring Trustee shall become effective, and the
successor Trustee shall have all the rights, powers and duties of the Trustee
under this Indenture. The Company shall mail a notice of the successor Trustee's
succession to the Holders. The retiring Trustee shall promptly transfer all
property held by it as Trustee to the successor Trustee. Notwithstanding
replacement of the Trustee pursuant to this Section 5.9, the Company's
obligations under Section 5.8 hereof shall continue for the benefit of the
retiring Trustee with respect to expenses, losses and liabilities incurred by it
prior to such replacement.

         SECTION 5.10  SUCCESSOR TRUSTEE BY MERGER, ETC.

         Subject to Section 5.11 hereof, if the Trustee consolidates with,
merges or converts into, or transfers or sells all or substantially all of its
corporate trust business to, another corporation or national banking
association, the successor entity without any further act shall be the successor
Trustee as to the Securities.

         SECTION 5.11  CORPORATE TRUSTEE REQUIRED; ELIGIBILITY.

         The Trustee shall at all times satisfy the requirements of Section
310(a)(1), (2) and (5) of the TIA. The Trustee shall at all times have (or, in
the case of a corporation included in a bank holding company system, the related
bank holding company shall at all times have), a combined capital and surplus of
at least $100 million as set forth in its (or its related bank holding
company's) most recent published annual report of condition. The Trustee is
subject to Section 310(b) of the TIA.

         SECTION 5.12  COLLECTION OF CLAIMS AGAINST THE COMPANY.

         The Trustee is subject to Section 311(a) of the TIA, excluding any
creditor relationship listed in Section 311(b) of the TIA. A Trustee who has
resigned or been removed shall be subject to Section 311(a) of the TIA to the
extent indicated therein.


                                     45



                                  ARTICLE 6

              CONSOLIDATION, MERGER, CONVEYANCE, TRANSFER OR LEASE

         SECTION 6.1  COMPANY MAY CONSOLIDATE, ETC., ONLY ON CERTAIN TERMS.

         The Company shall not consolidate with or merge into any other Person
or convey, transfer or lease its properties and assets substantially as an
entirety to any Person, and the Company shall not permit any Person to
consolidate with or merge into the Company or convey, transfer or lease its
properties and assets substantially as an entirety to the Company, unless:

                   (1) in the event that the Company shall consolidate with
         or merge into another Person or convey, transfer or lease its
         properties and assets substantially as an entirety to any Person,
         the Person formed by such consolidation or into which the Company is
         merged or the Person which acquires by conveyance or transfer, or
         which leases, the properties and assets of the Company substantially
         as an entirety shall be a corporation, limited liability company,
         partnership or trust organized and validly existing under the laws
         of the United States of America, any State thereof or the District
         of Columbia and, if the entity surviving such transaction or
         transferee entity is not the Company, then such surviving or
         transferee entity shall expressly assume, by an indenture

         It shall not be necessary for any Act of Holders of Securities under

indenture, but it shall be sufficient if such Act shall approve the substance
thereof.

         SECTION 7.3  COMPLIANCE WITH TRUST INDENTURE ACT.

         Every amendment to this Indenture or the Securities shall be set forth
in a supplemental indenture that complies with the TIA as then in effect.

         SECTION 7.4  REVOCATION OF CONSENTS AND EFFECT OF CONSENTS OR VOTES.

         Until an amendment, supplement or waiver becomes effective, a written
consent to it by a Holder is a continuing consent by the Holder and every
subsequent Holder of a Security or portion of a Security that evidences the same
debt as the consenting Holder's Security, even if notation of the consent is not
made on any Security; provided, however, that unless a record date shall have
been established, any such Holder or subsequent Holder may revoke the consent as
to its Security or portion of a Security if the Trustee receives written notice
of revocation before the date the amendment, supplement or waiver becomes
effective.

         An amendment, supplement or waiver becomes effective on receipt by the
Trustee of written consents from or affirmative votes by, as the case may be,
the Holders of the requisite percentage of aggregate principal amount of the
Outstanding Securities, and thereafter shall bind every Holder of Securities;
provided, however, if the amendment, supplement or waiver makes a change
described in any of the clauses (a) through (j) of Section 7.2 hereof, the
amendment, supplement or waiver shall bind only each Holder of a Security which
has consented to it or voted for it, as the case may be, and every subsequent
Holder of a Security or portion of a Security that evidences the same
indebtedness as the Security of the consenting or affirmatively voting, as the
case may be, Holder.

         SECTION 7.5  NOTATION ON OR EXCHANGE OF SECURITIES.

         If an amendment, supplement or waiver changes the terms of a Security:

         (a) the Trustee may require the Holder of a Security to deliver such
Securities to the Trustee, the Trustee may place an appropriate notation on
the Security about the changed terms and return it to the Holder and the
Trustee may place an appropriate notation on any Security thereafter
authenticated; or

         (b) if the Company or the Trustee so determines, the Company in
exchange for the Security shall issue and the Trustee shall authenticate a
new Security that reflects the changed terms.

         Failure to make the appropriate notation or issue a new Security shall
not affect the validity and effect of such amendment, supplement or waiver.


                                      50



         SECTION 7.6       TRUSTEE TO SIGN AMENDMENT, ETC.

         The Trustee shall sign any amendment authorized pursuant to this
Article 7 if the amendment does not adversely affect the rights, duties,
liabilities or immunities of the Trustee in any material respects. If the
amendment does adversely affect the rights, duties, liabilities or immunities of
the Trustee, the Trustee may but need not sign it. In signing or refusing to
sign such amendment, the Trustee shall be entitled to receive and shall be fully
protected in relying upon an Officers' Certificate and an Opinion of Counsel as
conclusive evidence that such amendment is authorized or permitted by this
Indenture.

entitled to one vote for each $1,000 principal amount of Securities held or
represented by him; provided, however, that no vote shall be cast or counted
at any meeting in respect of any Security challenged as not Outstanding and
ruled by the chairman of the meeting to be not Outstanding. The chairman of

proxy.

         The vote upon any resolution submitted to any meeting of Holders of
Securities shall be by written ballots on which shall be subscribed the

the inspectors of votes on any vote by ballot taken thereat and affidavits by
one or more Persons having knowledge of the facts setting forth a copy of the

of the meeting and one such copy shall be delivered to the Company and
another to the Trustee to be preserved by the Trustee, the latter to have
attached thereto the ballots voted at the meeting. Any record so signed and
verified shall be conclusive evidence of the matters therein stated.

         Any time prior to October 17, 2003, the Company may, at its option,
redeem the Securities in whole or in part on any date from time to time, upon
notice as set forth in Section 10.5, at a redemption price equal to $1,000
per $1,000 principal amount of the Securities redeemed (such amount, together
with the Make-Whole Payment described below, the "Provisional Redemption
Price"), on the date of redemption (the "Provisional Redemption Date") if (i)
the Closing Price of the Common Stock has exceeded 150% of the Conversion
Price (as defined in Article 12 and as such may be adjusted from time to
time) then in effect for at least 20 Trading Days in any consecutive
30-Trading Day period ending on the Trading Day prior to the date of mailing
of the provisional notice of redemption pursuant to Section 10.5 (the "Notice
Date"), and (ii) a registration statement covering resales of the Securities
and the Common Stock issuable upon conversion thereof is effective and
available for use and is expected to remain effective for the 30 days
following the Provisional Redemption Date (such redemption, a "Provisional
Redemption").

         Upon any such Provisional Redemption, the Company shall make an
additional payment (the "Make-Whole Payment") with respect to the Securities
called for redemption to Holders on the Notice Date in an amount equal to
$105.00 per $1,000 principal amount of the Securities, less the amount of any
interest actually paid on such Securities prior to the Provisional Redemption
Date. The Company shall make the Make-Whole Payment on all Securities called
for Provisional Redemption, including those Securities converted into Common
Stock between the Notice Date and the Provisional Redemption Date.

         The Company may elect to pay the Make-Whole Payment or any portion
thereof (i) in cash or, (ii) subject to the fulfillment by the Company of the
conditions set forth in the following paragraph, by delivering the number of
shares of Common Stock equal to (x) the Make-Whole Payment (or any portion
thereof that the Company elects to pay in shares of Common Stock) divided by
(y) 97% of the average of the Closing Prices per share of Common Stock for
the five consecutive Trading Days immediately preceding and including the
first Trading Day prior to the Provisional Redemption Date.

         The following shall constitute the conditions to any election by the
Company pursuant to this Section 10.1 to pay the Make-Whole Payment (or any
portion thereof) in shares of Common Stock:

         (a) The shares of Common Stock to be issued in payment of the
Make-Whole Payment (or any portion thereof) hereunder shall not require
registration under any federal securities law before such shares may be
freely transferable without being subject to any transfer restrictions under
the Securities Act, or, if registration is required, such registration shall
be completed and shall become effective prior to the Provisional Redemption
Date (and the Company shall state in the notice of Provisional Redemption
that the Company expects that such registration shall remain effective for at
least 30 days following the Provisional Redemption Date);


                                      58



         (b) The shares of Common Stock to be issued in payment of the
Make-Whole Payment (or any portion thereof) hereunder shall not require
registration with, or approval of, any governmental authority under any state
law or any other federal law before such shares may be validly issued or
delivered or if such registration is required or such approval must be
obtained, such registration shall be completed or such approval shall be
obtained prior to the Provisional Redemption Date;

         (c) The shares of Common Stock to be issued upon payment of the
Make-Whole Payment (or any portion thereof) hereunder are, or shall have
been, approved for listing on the Nasdaq National Market or the New York
Stock Exchange or listed on another national securities exchange, in any
case, prior to the Provisional Redemption Date;

         (d) All shares of Common Stock which may be issued upon payment of
the Make-Whole Payment (or any portion thereof) will be issued out of the
Company's authorized but unissued Common Stock and will, upon issue, be duly
and validly issued and fully paid and nonassessable and free of any
preemptive or similar rights; and

         (e) If any of the conditions set forth in clauses (a) through (d) of
this paragraph are not satisfied in accordance with the terms thereof, the
Make-Whole Payment shall be paid by the Company only in cash.

         SECTION 10.2      OPTIONAL REDEMPTION.

         Except as set forth under Section 10.1, the Securities are not
redeemable prior to October 17, 2003 (the "Optional Redemption Date"). On or
after October 17, 2003, the Company may, at its option, redeem the Securities
in whole at any time or in part from time to time, on any date prior to
maturity, upon notice as set forth in Section 10.5, at the redemption price
(expressed as percentages of the principal amount) set forth below if
redeemed during the 12-month period beginning October 17 of the years
indicated and ending October 16 of the following year:

During the Twelve Months Commencing Redemption Price ----------------- ---------------- 2003.............................. 102.00% 2004.............................. 101.50% 2005.............................. 101.00% 2006.............................. 100.50%
("the Optional Redemption Price"), plus any interest accrued but not paid prior to the Optional Redemption Date, only if the Closing Price of the Common Stock has exceeded 120% of the Conversion Price (as defined in Article 12 and as such may be adjusted from time to time) then in effect for at least 20 Trading Days in any consecutive 30 Trading Day period ending on the Trading Day immediately prior to the date of mailing of the notice of optional redemption pursuant to Section 10.5. 59 SECTION 10.3 NOTICE TO TRUSTEE. If the Company elects to redeem Securities pursuant to the redemption provisions of Section 10.1 or Section 10.2 hereof, it shall notify the Trustee at least 30 days prior to the Redemption Date of such intended Redemption Date, the principal amount of Securities to be redeemed, the CUSIP numbers of the Securities to be redeemed and, in the case of a Provisional Redemption, of whether the Make-Whole Payment shall be paid by the Company (x) in cash, (y) by delivery of shares of Common Stock or (z) in a combination of cash and delivery of shares of Common Stock, in which case, the portion of the Make-Whole Payment that will be paid in cash and the portion that will be paid in shares of Common Stock. SECTION 10.4 SELECTION OF SECURITIES TO BE REDEEMED. If fewer than all the Securities are to be redeemed, the Trustee shall select the particular Securities to be redeemed from the Outstanding Securities by a method that complies with the requirements of any exchange on which the Securities are listed, or, if the Securities are not listed on an exchange, on a pro rata basis or by lot or in accordance with any other method the Trustee considers fair and appropriate. Securities and portions thereof that the Trustee selects shall be in amounts equal to the minimum authorized denominations for Securities to be redeemed or any integral multiple thereof. If any Security selected for partial redemption is converted in part before termination of the conversion right with respect to the portion of the Security so selected, the converted portion of such Security shall be deemed to be the portion selected for redemption (provided, however, that the Holder of such Security so converted and deemed redeemed shall not be entitled to any additional interest payment as a result of such deemed redemption than such Holder would have otherwise been entitled to receive upon conversion of such Security). Securities which have been converted during a selection of Securities to be redeemed may be treated by the Trustee as Outstanding for the purpose of such selection. The Trustee shall promptly notify the Company and the Registrar in writing of the Securities selected for redemption and, in the case of any Securities selected for partial redemption, the principal amount thereof to be redeemed. For all purposes of this Indenture, unless the context otherwise requires, all provisions relating to the redemption of Securities shall relate, in the case of any Securities redeemed or to be redeemed only in part, to the portion of the principal amount of such Securities which has been or is to be redeemed. SECTION 10.5 NOTICE OF REDEMPTION. Notice of redemption shall be given in the manner provided in Section 14.2 hereof to the Holders of Securities to be redeemed. Such notice shall be given not less than 20 nor more than 60 days prior to the Redemption Date. All notices of redemption shall state: (1) the Redemption Date; 60 (2) the Redemption Price and interest accrued and unpaid to the Redemption Date, if any; (3) with respect to a Provisional Redemption, whether the Make-Whole Payment shall be paid by the Company (x) in cash, (y) by delivery of shares of Common Stock or (z) in a combination of cash and delivery of shares of Common Stock, in which case, the portion of the Make-Whole Payment that will be paid in cash and the portion that will be paid in shares of Common Stock; (4) if fewer than all the Outstanding Securities are to be redeemed, the aggregate principal amount of Securities to be redeemed and the aggregate principal amount of Securities which will be outstanding after such partial redemption; (5) that on the Redemption Date the Redemption Price and interest accrued and unpaid to the Redemption Date, if any, will become due and payable upon each such Security to be redeemed, and that interest thereon shall cease to accrue on and after such date; (6) the Conversion Price, the date on which the right to convert the principal of the Securities to be redeemed will terminate and the places where such Securities may be surrendered for conversion; (7) the place or places where such Securities are to be surrendered for payment of the Redemption Price and accrued and unpaid interest, if any; and (8) the CUSIP number of the Securities. The notice given shall specify the last date on which exchanges or transfers of Securities may be made pursuant to Section 2.1 hereof, and shall specify the serial numbers of Securities and the portions thereof called for redemption. Notice of redemption of Securities to be redeemed at the election of the Company shall be given by the Company or, at the Company's request, by the Trustee in the name of and at the expense of the Company. SECTION 10.6 EFFECT OF NOTICE OF REDEMPTION. Notice of redemption having been given as provided in Section 10.5 hereof, the Securities so to be redeemed shall, on the Redemption Date, become due and payable at the Redemption Price therein specified and from and after such date (unless the Company shall default in the payment of the Redemption Price and accrued and unpaid interest) such Securities shall cease to bear interest. Upon surrender of any such Security for redemption in accordance with such notice, such Security shall be paid by the Company at the Redemption Price; provided, however, the installments of interest on Securities whose Stated Maturity is prior to or on the Redemption Date shall be payable to the Holders of such Securities, or one or more Predecessor Securities, registered as such on the relevant Record Date according to their terms and the provisions of Section 2.1 hereof. 61 If any Security called for redemption shall not be so paid upon surrender thereof for redemption, the principal and premium, if any, shall, until paid, bear interest from the Redemption Date at the Interest Rate. SECTION 10.7 DEPOSIT OF REDEMPTION PRICE. Prior to or on any Redemption Date, the Company shall deposit with the Trustee or with a Paying Agent an amount of money sufficient to pay the Redemption Price of all the Securities to be redeemed on that Redemption Date, other than any Securities called for redemption on that date which have been converted prior to the date of such deposit, and accrued and unpaid interest, if any, on such Securities. If any Security called for redemption is converted, any money deposited with the Trustee or with a Paying Agent or so segregated and held in trust for the redemption of such Security shall (subject to any right of the Holder of such Security or any Predecessor Security to receive interest as provided in the fourth to last paragraph of Section 2.1 hereof) be paid to the Company at the Company's request or, if then held by the Company, shall be discharged from such trust. SECTION 10.8 SECURITIES REDEEMED IN PART. Any Security which is to be redeemed only in part shall be surrendered at an office or agency of the Company designated for that purpose pursuant to Section 9.2 hereof (with, if the Company or the Trustee so requires, due endorsement by, or a written instrument of transfer in form satisfactory to the Company and the Trustee duly executed by, the Holder thereof or the Holder's attorney duly authorized in writing), and the Company shall execute, and the Trustee shall authenticate and deliver to the Holder of such Security without service charge, a new Security or Securities of any authorized denomination as requested by such Holder in aggregate principal amount equal to and in exchange for the unredeemed portion of the principal of the Security so surrendered. 62 ARTICLE 11 REPURCHASE AT THE OPTION OF A HOLDER UPON A CHANGE OF CONTROL SECTION 11.1 REPURCHASE RIGHT. In the event that a Change in Control shall occur, each Holder shall have the right (the "Repurchase Right"), at the Holder's option, but subject to the provisions of Section 11.2 hereof, to require the Company to repurchase, and upon the exercise of such right the Company shall repurchase, all of such Holder's Securities not theretofore called for redemption, or any portion of the principal amount thereof that is equal to $1,000 or any integral multiple thereof (provided that no single Security may be repurchased in part unless the portion of the principal amount of such Security to be Outstanding after such repurchase is equal to $1,000 or integral multiples thereof), on the date (the "Repurchase Date") that is 45 days after the date of the Company Notice (as defined in Section 11.3) at a purchase price equal to 100% of the principal amount of the Securities to be repurchased (the "Repurchase Price"), plus interest accrued and unpaid to, but excluding, the Repurchase Date; provided, however, that installments of interest on Securities whose Stated Maturity is prior to or on the Repurchase Date shall be payable to the Holders of such Securities, or one or more Predecessor Securities, registered as such on the relevant Record Date according to their terms and the provisions of Section 2.1 hereof. Subject to the fulfillment by the Company of the conditions set forth in Section 11.2 hereof, the Company may elect to pay the Repurchase Price by delivering the number of shares of Common Stock equal to (i) the Repurchase Price divided by (ii) 95% of the average of the Closing Prices per share of Common Stock for the five consecutive Trading Days immediately preceding and including the third Trading Day prior to the Repurchase Date. Whenever in this Indenture (including Sections 2.2, 4.1(a) and 4.7 hereof) or Exhibit A annexed hereto there is a reference, in any context, to the principal of any Security as of any time, such reference shall be deemed to include reference to the Repurchase Price payable in respect to such Security to the extent that such Repurchase Price is, was or would be so payable at such time, and express mention of the Repurchase Price in any provision of this Indenture shall not be construed as excluding the Repurchase Price in those provisions of this Indenture when such express mention is not made; provided, however, that, for the purposes of Article 13 hereof, such reference shall be deemed to include reference to the Repurchase Price only to the extent the Repurchase Price is payable in cash. SECTION 11.2 CONDITIONS TO THE COMPANY'S ELECTION TO PAY THE REPURCHASE PRICE IN COMMON STOCK. (a) The shares of Common Stock to be issued upon repurchase of Securities hereunder: (i) shall not require registration under any federal securities law before such shares may be freely transferable without being subject to any transfer restrictions under the Securities Act upon repurchase or, if such registration is required, such registration shall be completed and shall become effective prior to the Repurchase Date; and 63 (ii) shall not require registration with, or approval of, any governmental authority under any state law or any other federal law before shares may be validly issued or delivered upon repurchase or if such registration is required or such approval must be obtained, such registration shall be completed or such approval shall be obtained prior to the Repurchase Date. (b) The shares of Common Stock to be listed upon repurchase of Securities hereunder are, or shall have been, approved for listing on the Nasdaq National Market or the New York Stock Exchange or listed on another national securities exchange, in any case, prior to the Repurchase Date. (c) All shares of Common Stock which may be issued upon repurchase of Securities will be issued out of the Company's authorized but unissued Common Stock and will, upon issue, be duly and validly issued and fully paid and nonassessable and free of any preemptive or similar rights. (d) If any of the conditions set forth in clauses (a) through (c) of this Section 11.2 are not satisfied in accordance with the terms thereof, the Repurchase Price shall be paid by the Company only in cash. SECTION 11.3 NOTICES; METHOD OF EXERCISING REPURCHASE RIGHT, ETC. (a) Unless the Company shall have theretofore called for redemption all of the Outstanding Securities, prior to or on the 30th day after the occurrence of a Change in Control, the Company, or, at the written request and expense of the Company prior to or on the 30th day after such occurrence, the Trustee, shall give to all Holders of Securities notice, in the manner provided in Section 14.2 hereof, of the occurrence of the Change of Control and of the Repurchase Right set forth herein arising as a result thereof (the "Company Notice"). The Company shall also deliver a copy of such notice of a Repurchase Right to the Trustee. Each notice of a Repurchase Right shall state: (1) the Repurchase Date; (2) the date by which the Repurchase Right must exercised; (3) the Repurchase Price and accrued and unpaid interest, if any, and whether the Repurchase Price shall be paid by the Company in cash or by delivery of shares of Common Stock; (4) a description of the procedure which a Holder must follow to exercise a Repurchase Right, and the place or places where such Securities, are to be surrendered for payment of the Repurchase Price and accrued and unpaid interest, if any; (5) that on the Repurchase Date the Repurchase Price and accrued and unpaid interest, if any, will become due and payable upon each such Security designated by the Holder to be repurchased, and that interest thereon shall cease to accrue on and after said date; 64 (6) the Conversion Rate then in effect, the date on which the right to convert the principal amount of the Securities to be repurchased will terminate and the place where such Securities may be surrendered for conversion, and (7) the place or places where such Securities, together with the Option to Elect Repayment Upon a Change of Control certificate included in Exhibit A annexed hereto are to be delivered for payment of the Repurchase Price and accrued and unpaid interest, if any. No failure of the Company to give the foregoing notices or defect therein shall limit any Holder's right to exercise a Repurchase Right or affect the validity of the proceedings for the repurchase of Securities. If any of the foregoing provisions or other provisions of this Article 11 are inconsistent with applicable law, such law shall govern. (b) To exercise a Repurchase Right, a Holder shall deliver to the Trustee prior to or on the 30th day after the date of the Company Notice: (1) written notice of the Holder's exercise of such right, which notice shall set forth the name of the Holder, the principal amount of the Securities to be repurchased (and, if any Security is to be repurchased in part, the serial number thereof, the portion of the principal amount thereof to be repurchased) and a statement that an election to exercise the Repurchase Right is being made thereby, and, in the event that the Repurchase Price shall be paid in shares of Common Stock, the name or names (with addresses) in which the certificate or certificates for shares of Common Stock shall be issued, and (2) the Securities with respect to which the Repurchase Right is being exercised. Such written notice shall be irrevocable, except that the right of the Holder to convert the Securities with respect to which the Repurchase Right is being exercised shall continue until the close of business on the Business Day immediately preceding the Repurchase Date. (c) In the event a Repurchase Right shall be exercised in accordance with the terms hereof, the Company shall pay or cause to be paid to the Trustee the Repurchase Price in cash or shares of Common Stock, as provided above, for payment to the Holder on the Repurchase Date or, if shares of Common Stock are to be paid, as promptly after the Repurchase Date as practicable, together with accrued and unpaid interest to the Repurchase Date payable in cash with respect to the Securities as to which the Repurchase Right has been exercised; provided, however, that installments of interest that mature prior to or on the Repurchase Date shall be payable in cash to the Holders of such Securities, or one or more Predecessor Securities, registered as such at the close of business on the relevant Regular Record Date. (d) If any Security (or portion thereof) surrendered for repurchase shall not be so paid on the Repurchase Date, the principal amount of such Security (or portion thereof, as the case may be) shall, until paid, bear interest to the extent permitted by applicable law from the Repurchase 66 Date at the Interest Rate, and each Security shall remain convertible into Common Stock until the principal of such Security (or portion thereof, as the case may be) shall have been paid or duly provided for. (e) Any Security which is to be repurchased only in part shall be surrendered to the Trustee (with, if the Company or the Trustee so requires, due endorsement by, or a written instrument of transfer in form satisfactory to the Company and the Trustee duly executed by the Holder thereof or his attorney duly authorized in writing), and the Company shall execute, and the Trustee shall authenticate and make available for delivery to the Holder of such Security without service charge, a new Security or Securities, containing identical terms and conditions, each in an authorized denomination in aggregate principal amount equal to and in exchange for the unrepurchased portion of the principal of the Security so surrendered. (f) Any issuance of shares of Common Stock in respect of the Repurchase Price shall be deemed to have been effected immediately prior to the close of business on the Repurchase Date and the Person or Persons in whose name or names any certificate or certificates for shares of Common Stock shall be issuable upon such repurchase shall be deemed to have become on the Repurchase Date the holder or holders of record of the shares represented thereby; provided, however, that any surrender for repurchase on a date when the stock transfer books of the Company shall be closed shall constitute the Person or Persons in whose name or names the certificate or certificates for such shares are to be issued as the record holder or holders thereof for all purposes at the opening of business on the next succeeding day on which such stock transfer books are open. No payment or adjustment shall be made for dividends or distributions on any Common Stock issued upon repurchase of any Security declared prior to the Repurchase Date. (g) No fractions of shares of Common Stock shall be issued upon repurchase of any Security or Securities. If more than one Security shall be repurchased from the same Holder and the Repurchase Price shall be payable in shares of Common Stock, the number of full shares which shall be issued upon such repurchase shall be computed on the basis of the aggregate principal amount of the Securities (or specified portions thereof) to be so repurchased. Instead of any fractional share of Common Stock which would otherwise be issued on the repurchase of any Security or Securities (or specified portions thereof), the Company shall pay a cash adjustment in respect of such fraction (calculated to the nearest one-100th of a share) in an amount equal to the same fraction of the Quoted Price of the Common Stock as of the Trading Day preceding the Repurchase Date. (h) Any issuance and delivery of certificates for shares of Common Stock on repurchase of Securities shall be made without charge to the Holder of Securities being repurchased for such certificates or for any tax or duty in respect of the issuance or delivery of such certificates or the Securities represented thereby; provided, however, that the Company shall not be required to pay any tax or duty which may be payable in respect of (i) income of the Holder or (ii) any transfer involved in the issuance or delivery of certificates for shares of Common Stock in a name other than that of the Holder of the Securities being repurchased, and no such issuance or delivery shall be made unless the Persons requesting such issuance or delivery has paid to the Company the amount of any such tax or duty or has established, to the satisfaction of the Company, that such tax or duty has been paid. 66 (i) All Securities delivered for repurchase shall be delivered to the Trustee to be canceled at the direction of the Trustee, which shall dispose of the same as provided in Section 2.15 hereof. 67 ARTICLE 12 CONVERSION OF SECURITIES SECTION 12.1 CONVERSION RIGHT AND CONVERSION PRICE. Subject to and upon compliance with the provisions of this Article, at the option of the Holder thereof, any Security or any portion of the principal amount thereof which is $1,000 or an integral multiple of $1,000 may be converted at the principal amount thereof, or of such portion thereof, into duly authorized, fully paid and nonassessable shares of Common Stock, at the Conversion Price, determined as hereinafter provided, in effect at the time of conversion. Such conversion right shall expire at the close of business on October 17, 2007. In case a Security or portion thereof is called for redemption, such conversion right in respect of the Security or the portion so called, shall expire at the close of business on the second Business Day preceding the Redemption Date, unless the Company defaults in making the payment due upon redemption. In the case of a Change of Control for which the Holder exercises its Repurchase Right with respect to a Security or portion thereof, such conversion right in respect of the Security or portion thereof shall expire at the close of business on the Business Day immediately preceding the Repurchase Date. The price at which shares of Common Stock shall be delivered upon conversion (the "Conversion Price") shall be initially equal to $50.46 per share of Common Stock. The Conversion Price shall be adjusted in certain instances as provided in paragraphs (a), (b), (c), (d), (e), (f), (h) and (i) of Section 12.4 hereof. SECTION 12.2 EXERCISE OF CONVERSION RIGHT. To exercise the conversion right, the Holder of any Security to be converted shall surrender such Security duly endorsed or assigned to the Company or in blank, at the office of any Conversion Agent, accompanied by a duly signed conversion notice substantially in the form attached to the Security to the Company stating that the Holder elects to convert such Security or, if less than the entire principal amount thereof is to be converted, the portion thereof to be converted. Securities surrendered for conversion during the period from the close of business on any Regular Record Date to the opening of business on the next succeeding Interest Payment Date (except in the case of any Security whose Maturity is prior to such Interest Payment Date) shall be accompanied by payment in New York Clearing House funds or other funds acceptable to the Company of an amount equal to the interest to be received on such Interest Payment Date on the principal amount of Securities being surrendered for conversion. Securities shall be deemed to have been converted immediately prior to the close of business on the day of surrender of such Securities for conversion in accordance with the foregoing provisions, and at such time the rights of the Holders of such Securities as Holders shall cease, and the Person or Persons entitled to receive the Common Stock issuable upon conversion shall be treated for all purposes as the record holder or holders of such Common Stock at such time. As promptly as practicable on or after the conversion date, the Company 68 shall cause to be issued and delivered to such Conversion Agent a certificate or certificates for the number of full shares of Common Stock issuable upon conversion, together with payment in lieu of any fraction of a share as provided in Section 12.3 hereof. In the case of any Security which is converted in part only, upon such conversion the Company shall execute and the Trustee shall authenticate and deliver to the Holder thereof, at the expense of the Company, a new Security or Securities of authorized denominations in aggregate principal amount equal to the unconverted portion of the principal amount of such Securities. If shares of Common Stock to be issued upon conversion of a Restricted Security, or Securities to be issued upon conversion of a Restricted Security in part only, are to be registered in a name other than that of the Holder of such Restricted Security, such Holder must deliver to the Conversion Agent a certificate in substantially the form set forth in the form of Security set forth in Exhibit A annexed hereto, dated the date of surrender of such Restricted Security and signed by such Holder, as to compliance with the restrictions on transfer applicable to such Restricted Security. Neither the Trustee nor any Conversion Agent, Registrar or Transfer Agent shall be required to register in a name other than that of the Holder shares of Common Stock or Securities issued upon conversion of any such Restricted Security not so accompanied by a properly completed certificate. The Company hereby initially appoints the Trustee as the Conversion Agent. SECTION 12.3 FRACTIONS OF SHARES. No fractional shares of Common Stock shall be issued upon conversion of any Security or Securities. If more than one Security shall be surrendered for conversion at one time by the same Holder, the number of full shares which shall be issued upon conversion thereof shall be computed on the basis of the aggregate principal amount of the Securities (or specified portions thereof) so surrendered. Instead of any fractional share of Common Stock which would otherwise be issued upon conversion of any Security or Securities (or specified portions thereof), the Company shall pay a cash adjustment in respect of such fraction (calculated to the nearest one-100th of a share) in an amount equal to the same fraction of the Quoted Price of the Common Stock as of the Trading Day preceding the date of conversion. SECTION 12.4 ADJUSTMENT OF CONVERSION PRICE. The Conversion Price shall be subject to adjustments, calculated by the Company, from time to time as follows: (a) In case the Company shall hereafter pay a dividend or make a distribution to all holders of the outstanding Common Stock in shares of Common Stock, the Conversion Price in effect at the opening of business on the date following the date fixed for the determination of stockholders entitled to receive such dividend or other distribution shall be reduced by multiplying such Conversion Price by a fraction: (i) the numerator of which shall be the number of shares of Common Stock outstanding at the close of business on the Record Date (as defined in Section 12.4(g)) fixed for such determination, and 69 (ii) the denominator of which shall be the sum of such number of shares and the total number of shares constituting such dividend or other distribution. Such reduction shall become effective immediately after the opening of business on the day following the Record Date. If any dividend or distribution of the type described in this Section 12.4(a) is declared but not so paid or made, the Conversion Price shall again be adjusted to the Conversion Price which would then be in effect if such dividend or distribution had not been declared. (b) In case the outstanding shares of Common Stock shall be subdivided into a greater number of shares of Common Stock, the Conversion Price in effect at the opening of business on the day following the day upon which such subdivision becomes effective shall be proportionately reduced, and conversely, in case outstanding shares of Common Stock shall be combined into a smaller number of shares of Common Stock, the Conversion Price in effect at the opening of business on the day following the day upon which such combination becomes effective shall be proportionately increased, such reduction or increase, as the case may be, to become effective immediately after the opening of business on the day following the day upon which such subdivision or combination becomes effective. (c) In case the Company shall issue rights or warrants (other than any rights or warrants referred to in Section 12.4(d)) to all holders of its outstanding shares of Common Stock entitling them to subscribe for or purchase shares of Common Stock (or securities convertible into Common Stock) at a price per share (or having a conversion price per share) less than the Current Market Price (as defined in Section 12.4(g)) on the Record Date fixed for the determination of stockholders entitled to receive such rights or warrants, the Conversion Price shall be adjusted so that the same shall equal the price determined by multiplying the Conversion Price in effect at the opening of business on the date after such Record Date by a fraction: (i) the numerator of which shall be the number of shares of Common Stock outstanding at the close of business on the Record Date plus the number of shares which the aggregate offering price of the total number of shares so offered for subscription or purchase (or the aggregate conversion price of the convertible securities so offered) would purchase at such Current Market Price, and (ii) the denominator of which shall be the number of shares of Common Stock outstanding on the close of business on the Record Date plus the total number of additional shares of Common Stock so offered for subscription or purchase (or into which the convertible securities so offered are convertible). Such adjustment shall become effective immediately after the opening of business on the day following the Record Date fixed for determination of stockholders entitled to receive such rights or warrants. To the extent that shares of Common Stock (or securities convertible into Common Stock) are not delivered pursuant to such rights or warrants, upon the expiration or termination of such rights or warrants the Conversion Price shall be readjusted to the Conversion Price which would then be in effect had the adjustments made upon the issuance of such rights or warrants been made on the basis of the delivery of only the number of shares of Common Stock (or 70 securities convertible into Common Stock) actually delivered. In the event that such rights or warrants are not so issued, the Conversion Price shall again be adjusted to be the Conversion Price which would then be in effect if such date fixed for the determination of stockholders entitled to receive such rights or warrants had not been fixed. In determining whether any rights or warrants entitle the holders to subscribe for or purchase shares of Common Stock at less than such Current Market Price, and in determining the aggregate offering price of such shares of Common Stock, there shall be taken into account any consideration received for such rights or warrants, the value of such consideration if other than cash, to be determined by the Board of Directors. (d) In case the Company shall, by dividend or otherwise, distribute to all holders of its Common Stock shares of any class of capital stock of the Company (other than any dividends or distributions to which Section 12.4(a) applies) or evidences of its indebtedness, cash or other assets, including securities, but excluding (1) any rights or warrants referred to in Section 12.4(c), (2) any stock, securities or other property or assets (including cash) distributed in connection with a reclassification, change, merger, consolidation, statutory share exchange, combination, sale or conveyance to which Section 12.11 hereof applies and (3) dividends and distributions paid exclusively in cash (the securities described in foregoing clauses (1), (2) and (3) hereinafter in this Section 12.4(d) called the "securities"), then, in each such case, subject to the second succeeding paragraph of this Section 12.4(d), the Conversion Price shall be reduced so that the same shall be equal to the price determined by multiplying the Conversion Price in effect immediately prior to the close of business on the Record Date (as defined in Section 12.4(g)) with respect to such distribution by a fraction: (i) the numerator of which shall be the Current Market Price (determined as provided in Section 12.4(g)) on such date less the fair market value (as determined by the Board of Directors, whose determination shall be conclusive and set forth in a Board Resolution) on such date of the portion of the securities so distributed applicable to one share of Common Stock (determined on the basis of the number of shares of the Common Stock outstanding on the Record Date), and (ii) the denominator of which shall be such Current Market Price. Such reduction shall become effective immediately prior to the opening of business on the day following the Record Date. However, in the event that the then fair market value (as so determined) of the portion of the securities so distributed applicable to one share of Common Stock is equal to or greater than the Current Market Price on the Record Date, in lieu of the foregoing adjustment, adequate provision shall be made so that each Holder shall have the right to receive upon conversion of a Security (or any portion thereof) the amount of securities such Holder would have received had such Holder converted such Security (or portion thereof) immediately prior to such Record Date. In the event that such dividend or distribution is not so paid or made, the Conversion Price shall again be adjusted to be the Conversion Price which would then be in effect if such dividend or distribution had not been declared. If the Board of Directors determines the fair market value of any distribution for purposes of this Section 12.4(d) by reference to the actual or when issued trading market for any securities 71 comprising all or part of such distribution, it must in doing so consider the prices in such market over the same period (the "Reference Period") used in computing the Current Market Price pursuant to Section 12.4(g) to the extent possible, unless the Board of Directors in a Board Resolution determines in good faith that determining the fair market value during the Reference Period would not be in the best interest of the Holder. Rights or warrants distributed by the Company to all holders of Common Stock entitling the holders thereof to subscribe for or purchase shares of the Company's capital stock (either initially or under certain circumstances), which rights or warrants, until the occurrence of a specified event or events ("Trigger Event"): (i) are deemed to be transferred with such shares of Common Stock; (ii) are not exercisable; and (iii) are also issued in respect of future issuances of Common Stock, shall be deemed not to have been distributed for purposes of this Section 12.4(d) (and no adjustment to the Conversion Price under this Section 12.4(d) will be required) until the occurrence of the earliest Trigger Event. If such right or warrant is subject to subsequent events, upon the occurrence of which such right or warrant shall become exercisable to purchase different securities, evidences of indebtedness or other assets or entitle the holder to purchase a different number or amount of the foregoing or to purchase any of the foregoing at a different purchase price, then the occurrence of each such event shall be deemed to be the date of issuance and record date with respect to a new right or warrant (and a termination or expiration of the existing right or warrant without exercise by the holder thereof). In addition, in the event of any distribution (or deemed distribution) of rights or warrants, or any Trigger Event or other event (of the type described in the preceding sentence) with respect thereto, that resulted in an adjustment to the Conversion Price under this Section 12.4(d): (1) in the case of any such rights or warrants which shall all have been redeemed or repurchased without exercise by any holders thereof, the Conversion Price shall be readjusted upon such final redemption or repurchase to give effect to such distribution or Trigger Event, as the case may be, as though it were a cash distribution, equal to the per share redemption or repurchase price received by a holder of Common Stock with respect to such rights or warrant (assuming such holder had retained such rights or warrants), made to all holders of Common Stock as of the date of such redemption or repurchase, and (2) in the case of such rights or warrants all of which shall have expired or been terminated without exercise, the Conversion Price shall be readjusted as if such rights and warrants had never been issued. For purposes of this Section 12.4(d) and Sections 12.4(a), 12.4(b) and 12.4(c), any dividend or distribution to which this Section 12.4(d) is applicable that also includes shares of Common Stock, a subdivision or combination of Common Stock to which Section 12.4(b) applies, or rights or warrants to subscribe for or purchase shares of Common Stock to which Section 12.4(c) applies (or any combination thereof), shall be deemed instead to be: 72 (3) a dividend or distribution of the evidences of indebtedness, assets, shares of capital stock, rights or warrants other than such shares of Common Stock, such subdivision or combination or such rights or warrants to which Sections 12.4(a), 12.4(b) and 12.4(c) apply, respectively (and any Conversion Price reduction required by this Section 12.4(d) with respect to such dividend or distribution shall then be made), immediately followed by (4) a dividend or distribution of such shares of Common Stock, such subdivision or combination or such rights or warrants (and any further Conversion Price reduction required by Sections 12.4(a), 12.4(b) and 12.4(c) with respect to such dividend or distribution shall then be made), except: (A) the Record Date of such dividend or distribution shall be substituted as (x) "the date fixed for the determination of stockholders entitled to receive such dividend or other distribution", "Record Date fixed for such determinations" and "Record Date" within the meaning of Section 12.4(a), (y) "the day upon which such subdivision becomes effective" and "the day upon which such combination becomes effective" within the meaning of Section 12.4(b), and (z) as "the date fixed for the determination of stockholders entitled to receive such rights or warrants", "the Record Date fixed for the determination of the stockholders entitled to receive such rights or warrants" and such "Record Date" within the meaning of Section 12.4(c), and (B) any shares of Common Stock included in such dividend or distribution shall not be deemed "outstanding at the close of business on the date fixed for such determination" within the meaning of Section 12.4(a) and any reduction or increase in the number of shares of Common Stock resulting from such subdivision or combination shall be disregarded in connection with such dividend or distribution. (e) In case the Company shall, by dividend or otherwise, distribute to all holders of its Common Stock cash (excluding any cash that is distributed upon a reclassification, change, merger, consolidation, statutory share exchange, combination, sale or conveyance to which Section 12.11 hereof applies or as part of a distribution referred to in Section 12.4(d) hereof), in an aggregate amount that, combined together with: (1) the aggregate amount of any other such distributions to all holders of Common Stock made exclusively in cash within the 12 months preceding the date of payment of such distribution, and in respect of which no adjustment pursuant to this Section 12.4(e) has been made, and (2) the aggregate of any cash plus the fair market value (as determined by the Board of Directors, whose determination shall be conclusive and set forth in a Board Resolution) of consideration payable in respect of any tender offer by the Company or any of its subsidiaries for all or any portion of the Common Stock concluded within the 12 months preceding the date of such distribution, and in respect of which no adjustment pursuant to Section 12.4(f) hereof has been made, 73 exceeds 10% of the product of the Current Market Price (determined as provided in Section 12.4(g)) on the Record Date with respect to such distribution times the number of shares of Common Stock outstanding on such date, then and in each such case, immediately after the close of business on such date, the Conversion Price shall be reduced so that the same shall equal the price determined by multiplying the Conversion Price in effect immediately prior to the close of business on such Record Date by a fraction: (i) the numerator of which shall be equal to the Current Market Price on the Record Date less an amount equal to the quotient of (x) the excess of such combined amount over such 10% and (y) the number of shares of Common Stock outstanding on the Record Date, and (ii) the denominator of which shall be equal to the Current Market Price on such date. However, in the event that the then fair market value (as so determined) of the portion of the securities so distributed applicable to one share of Common Stock is equal to or greater than the Current Market Price on the Record Date, in lieu of the foregoing adjustment, adequate provision shall be made so that each Holder shall have the right to receive upon conversion of a Security (or any portion thereof) the amount of cash such Holder would have received had such Holder converted such Security (or portion thereof) immediately prior to such Record Date. In the event that such dividend or distribution is not so paid or made, the Conversion Price shall again be adjusted to be the Conversion Price which would then be in effect if such dividend or distribution had not been declared. (f) In case a tender offer made by the Company or any of its subsidiaries for all or any portion of the Common Stock shall expire and such tender offer (as amended upon the expiration thereof) shall require the payment to stockholders (based on the acceptance (up to any maximum specified in the terms of the tender offer) of Purchased Shares (as defined below)) of an aggregate consideration having a fair market value (as determined by the Board of Directors, whose determination shall be conclusive and set forth in a Board Resolution) that combined together with: (1) the aggregate of the cash plus the fair market value (as determined by the Board of Directors, whose determination shall be conclusive and set forth in a Board Resolution), as of the expiration of such tender offer, of consideration payable in respect of any other tender offers, by the Company or any of its subsidiaries for all or any portion of the Common Stock expiring within the 12 months preceding the expiration of such tender offer and in respect of which no adjustment pursuant to this Section 12.4(f) has been made, and (2) the aggregate amount of any distributions to all holders of the Company's Common Stock made exclusively in cash within 12 months preceding the expiration of such tender offer and in respect of which no adjustment pursuant to Section 12.4(e) has been made, exceeds 10% of the product of the Current Market Price (determined as provided in Section 12.4(g)) as of the last time (the "Expiration Time") tenders could have been made pursuant to such tender offer 74 (as it may be amended) times the number of shares of Common Stock outstanding (including any tendered shares) on the Expiration Time, then, and in each such case, immediately prior to the opening of business on the day after the date of the Expiration Time, the Conversion Price shall be adjusted so that the same shall equal the price determined by multiplying the Conversion Price in effect immediately prior to close of business on the date of the Expiration Time by a fraction: (i)the numerator of which shall be the number of shares of Common Stock outstanding (including any tendered shares) at the Expiration Time multiplied by the Current Market Price of the Common Stock on the Trading Day next succeeding the Expiration Time, and (ii) the denominator shall be the sum of (x) the fair market value (determined as aforesaid) of the aggregate consideration payable to stockholders based on the acceptance (up to any maximum specified in the terms of the tender offer) of all shares validly tendered and not withdrawn as of the Expiration Time (the shares deemed so accepted, up to any such maximum, being referred to as the "Purchased Shares") and (y) the product of the number of shares of Common Stock outstanding (less any Purchased Shares) on the Expiration Time and the Current Market Price of the Common Stock on the Trading Day next succeeding the Expiration Time. Such reduction (if any) shall become effective immediately prior to the opening of business on the day following the Expiration Time. In the event that the Company is obligated to purchase shares pursuant to any such tender offer, but the Company is permanently prevented by applicable law from effecting any such purchases or all such purchases are rescinded, the Conversion Price shall again be adjusted to be the Conversion Price which would then be in effect if such tender offer had not been made. If the application of this Section 12.4(f) to any tender offer would result in an increase in the Conversion Price, no adjustment shall be made for such tender offer under this Section 12.4(f). (g) For purposes of this Section 12.4, the following terms shall have the meanings indicated: (1) "Current Market Price" shall mean the average of the daily Closing Prices per share of Common Stock for the ten consecutive Trading Days immediately prior to the date in question; provided, however, that if: (i) the "ex" date (as hereinafter defined) for any event (other than the issuance or distribution requiring such computation) that requires an adjustment to the Conversion Price pursuant to Section 12.4(a), (b), (c), (d), (e) or (f) occurs during such ten consecutive Trading Days, the Closing Price for each Trading Day prior to the "ex" date for such other event shall be adjusted by multiplying such Closing Price by the same fraction by which the Conversion Price is so required to be adjusted as a result of such other event; 75 (ii) the "ex" date for any event (other than the issuance or distribution requiring such computation) that requires an adjustment to the Conversion Price pursuant to Section 12.4(a), (b), (c), (d), (e) or (f) occurs on or after the "ex" date for the issuance or distribution requiring such computation and prior to the day in question, the Closing Price for each Trading Day on and after the "ex" date for such other event shall be adjusted by multiplying such Closing Price by the reciprocal of the fraction by which the Conversion Price is so required to be adjusted as a result of such other event; and (iii) the "ex" date for the issuance or distribution requiring such computation is prior to the day in question, after taking into account any adjustment required pursuant to clause (i) or (ii) of this proviso, the Closing Price for each Trading Day on or after such "ex" date shall be adjusted by adding thereto the amount of any cash and the fair market value (as determined by the Board of Directors in a manner consistent with any determination of such value for purposes of Section 12.4(d) or (f), whose determination shall be conclusive and set forth in a Board Resolution) of the evidences of indebtedness, shares of capital stock or assets being distributed applicable to one share of Common Stock as of the close of business on the day before such "ex" date. For purposes of any computation under Section 12.4(f), the Current Market Price of the Common Stock on any date shall be deemed to be the average of the daily Closing Prices per share of Common Stock for such day and the next two succeeding Trading Days; provided, however, that if the "ex" date for any event (other than the tender offer requiring such computation) that requires an adjustment to the Conversion Price pursuant to Section 12.4(a), (b), (c), (d), (e) or (f) occurs on or after the Expiration Time for the tender or exchange offer requiring such computation and prior to the day in question, the Closing Price for each Trading Day on and after the "ex" date for such other event shall be adjusted by multiplying such Closing Price by the reciprocal of the fraction by which the Conversion Price is so required to be adjusted as a result of such other event. For purposes of this paragraph, the term "ex" date, when used: (A) with respect to any issuance or distribution, means the first date on which the Common Stock trades regular way on the relevant exchange or in the relevant market from which the Closing Price was obtained without the right to receive such issuance or distribution; (B) with respect to any subdivision or combination of shares of Common Stock, means the first date on which the Common Stock trades regular way on such exchange or in such market after the time at which such subdivision or combination becomes effective, and (C) with respect to any tender or exchange offer, means the first date on which the Common Stock trades regular way on such exchange or in such market after the Expiration Time of such offer. 76 Notwithstanding the foregoing, whenever successive adjustments to the Conversion Price are called for pursuant to this Section 12.4, such adjustments shall be made to the Current Market Price as may be necessary or appropriate to effectuate the intent of this Section 12.4 and to avoid unjust or inequitable results as determined in good faith by the Board of Directors. (2) "fair market value" shall mean the amount which a willing buyer would pay a willing seller in an arm's length transaction. (3) "Record Date" shall mean, with respect to any dividend, distribution or other transaction or event in which the holders of Common Stock have the right to receive any cash, securities or other property or in which the Common Stock (or other applicable security) is exchanged for or converted into any combination of cash, securities or other property, the date fixed for determination of stockholders entitled to receive such cash, securities or other property (whether such date is fixed by the Board of Directors or by statute, contract or otherwise). (h) The Company may make such reductions in the Conversion Price, in addition to those required by Sections 12.4(a), (b), (c), (d), (e) or (f), as the Board of Directors considers to be advisable to avoid or diminish any income tax to holders of Common Stock or rights to purchase Common Stock resulting from any dividend or distribution of stock (or rights to acquire stock) or from any event treated as such for income tax purposes. To the extent permitted by applicable law, the Company from time to time may reduce the Conversion Price by any amount for any period of time if the period is at least 20 days and the reduction is irrevocable during the period and the Board of Directors determines in good faith that such reduction would be in the best interests of the Company, which determination shall be conclusive and set forth in a Board Resolution. Whenever the Conversion Price is reduced pursuant to the preceding sentence, the Company shall mail to the Trustee and each Holder at the address of such Holder as it appears in the Register a notice of the reduction at least 15 days prior to the date the reduced Conversion Price takes effect, and such notice shall state the reduced Conversion Price and the period during which it will be in effect. (i) No adjustment in the Conversion Price shall be required unless such adjustment would require an increase or decrease of at least 1% in such price; provided, however, that any adjustments which by reason of this Section 12.4(i) are not required to be made shall be carried forward and taken into account in any subsequent adjustment. All calculations under this Article 12 shall be made by the Company and shall be made to the nearest cent or to the nearest one hundredth of a share, as the case may be. No adjustment need be made for a change in the par value or no par value of the Common Stock. (j) In any case in which this Section 12.4 provides that an adjustment shall become effective immediately after a Record Date for an event, the Company may defer until the occurrence of such event (i) issuing to the Holder of any Security converted after such Record Date and before the occurrence of such event the additional shares of Common Stock issuable upon such conversion by reason of the adjustment required by such event over and above the 77 Common Stock issuable upon such conversion before giving effect to such adjustment and (ii) paying to such holder any amount in cash in lieu of any fraction pursuant to Section 12.3 hereof. (k) For purposes of this Section 12.4, the number of shares of Common Stock at any time outstanding shall not include shares held in the treasury of the Company but shall include shares issuable in respect of scrip certificates issued in lieu of fractions of shares of Common Stock. The Company will not pay any dividend or make any distribution on shares of Common Stock held in the treasury of the Company. (l) If the distribution date for the rights provided in the Company's rights agreement, if any, occurs prior to the date a Security is converted, the Holder of the Security who converts such Security after the distribution date is not entitled to receive the rights that would otherwise be attached (but for the date of conversion) to the shares of Common Stock received upon such conversion; provided, however, that an adjustment shall be made to the Conversion Price pursuant to clause 12.4(b) as if the rights were being distributed to the common stockholders of the Company immediately prior to such conversion. If such an adjustment is made and the rights are later redeemed, invalidated or terminated, then a corresponding reversing adjustment shall be made to the Conversion Price, on an equitable basis, to take account of such event. SECTION 12.5 NOTICE OF ADJUSTMENTS OF CONVERSION PRICE. Whenever the Conversion Price is adjusted as herein provided (other than in the case of an adjustment pursuant to the second paragraph of Section 12.4(h) for which the notice required by such paragraph has been provided), the Company shall promptly file with the Trustee and any Conversion Agent other than the Trustee an Officers' Certificate setting forth the adjusted Conversion Price and showing in reasonable detail the facts upon which such adjustment is based. Promptly after delivery of such Officers' Certificate, the Company shall prepare a notice stating that the Conversion Price has been adjusted and setting forth the adjusted Conversion Price and the date on which each adjustment becomes effective, and shall mail such notice to each Holder at the address of such Holder as it appears in the Register within 20 days of the effective date of such adjustment. Failure to deliver such notice shall not effect the legality or validity of any such adjustment. SECTION 12.6 NOTICE PRIOR TO CERTAIN ACTIONS. In case at any time after the date hereof: (1) the Company shall declare a dividend (or any other distribution) on its Common Stock payable otherwise than in cash out of its capital surplus or its consolidated retained earnings; (2) the Company shall authorize the granting to the holders of its Common Stock of rights or warrants to subscribe for or purchase any shares of capital stock of any class (or of securities convertible into shares of capital stock of any class) or of any other rights; (3) there shall occur any reclassification of the Common Stock of the Company (other than a subdivision or combination of its outstanding Common Stock, a 78 change in par value, a change from par value to no par value or a change from no par value to par value), or any merger, consolidation, statutory share exchange or combination to which the Company is a party and for which approval of any shareholders of the Company is required, or the sale, transfer or conveyance of all or substantially all of the assets of the Company; or (4) there shall occur the voluntary or involuntary dissolution, liquidation or winding up of the Company; the Company shall cause to be filed at each office or agency maintained for the purpose of conversion of securities pursuant to Section 9.2 hereof, and shall cause to be provided to the Trustee and all Holders in accordance with Section 14.2 hereof, at least 20 days (or 10 days in any case specified in clause (1) or (2) above) prior to the applicable record or effective date hereinafter specified, a notice stating: (A) the date on which a record is to be taken for the purpose of such dividend, distribution, rights or warrants, or, if a record is not to be taken, the date as of which the holders of Common Stock of record to be entitled to such dividend, distribution, rights or warrants are to be determined, or (B) the date on which such reclassification, merger, consolidation, statutory share exchange, combination, sale, transfer, conveyance, dissolution, liquidation or winding up is expected to become effective, and the date as of which it is expected that holders of Common Stock of record shall be entitled to exchange their shares of Common Stock for securities, cash or other property deliverable upon such reclassification, merger, consolidation, statutory share exchange, sale, transfer, dissolution, liquidation or winding up. Neither the failure to give such notice nor any defect therein shall affect the legality or validity of the proceedings or actions described in clauses (1) through (4) of this Section 12.6. SECTION 12.7 COMPANY TO RESERVE COMMON STOCK. The Company shall at all times use its best efforts to reserve and keep available, free from preemptive rights, out of its authorized but unissued Common Stock, for the purpose of effecting the conversion of Securities, the full number of shares of fully paid and nonassessable Common Stock then issuable upon the conversion of all Outstanding Securities. SECTION 12.8 TAXES ON CONVERSIONS. Except as provided in the next sentence, the Company will pay any and all taxes (other than taxes on income) and duties that may be payable in respect of the issue or delivery of shares of Common Stock on conversion of Securities pursuant hereto. A Holder delivering a Security for conversion shall be liable for and will be required to pay any tax or duty which may be payable in respect of any transfer involved in the issue and delivery of shares of Common Stock in a name other than that of the Holder of the Security or Securities to be converted, and no such issue or delivery shall be made unless the Person requesting such issue has paid to the Company 79 the amount of any such tax or duty, or has established to the satisfaction of the Company that such tax or duty has been paid. SECTION 12.9 COVENANT AS TO COMMON STOCK. The Company covenants that all shares of Common Stock which may be issued upon conversion of Securities will upon issue be fully paid and nonassessable and, except as provided in Section 12.8, the Company will pay all taxes, liens and charges with respect to the issue thereof. SECTION 12.10 CANCELLATION OF CONVERTED SECURITIES. All Securities delivered for conversion shall be delivered to the Trustee to be canceled by or at the direction of the Trustee, which shall dispose of the same as provided in Section 2.9. SECTION 12.11 EFFECT OF RECLASSIFICATION, CONSOLIDATION, MERGER OR SALE. If any of following events occur, namely: (i) any reclassification or change of the outstanding shares of Common Stock (other than a change in par value, or from par value to no par value, or from no par value to par value, or as a result of a subdivision or combination), (ii) any merger, consolidation, statutory share exchange or combination of the Company with another corporation as a result of which holders of Common Stock shall be entitled to receive stock, securities or other property or assets (including cash) with respect to or in exchange for such Common Stock or (iii) any sale or conveyance of the properties and assets of the Company as, or substantially as, an entirety to any other corporation as a result of which holders of Common Stock shall be entitled to receive stock, securities or other property or assets (including cash) with respect to or in exchange for such Common Stock, the Company or the successor or purchasing corporation, as the case may be, shall execute with the Trustee a supplemental indenture (which shall comply with the TIA as in force at the date of execution of such supplemental indenture if such supplemental indenture is then required to so comply) providing that such Security shall be convertible into the kind and amount of shares of stock and other securities or property or assets (including cash) which such Holder would have been entitled to receive upon such reclassification, change, merger, consolidation, statutory share exchange, combination, sale or conveyance had such Securities been converted into Common Stock immediately prior to such reclassification, change, merger, consolidation, statutory share exchange, combination, sale or conveyance assuming such holder of Common Stock did not exercise its rights of election, if any, as to the kind or amount of securities, cash or other property receivable upon such reclassification, change, merger, consolidation, statutory share exchange, combination, sale or conveyance (provided that, if the kind or amount of securities, cash or other 80 property receivable upon such reclassification, change, merger, consolidation, statutory share exchange, combination, sale or conveyance is not the same for each share of Common Stock in respect of which such rights of election shall not have been exercised ("Non-Electing Share"), then for the purposes of this Section 12.11 the kind and amount of securities, cash or other property receivable upon such reclassification, change, merger, consolidation, statutory share exchange, combination, sale or conveyance for each Non-Electing Share shall be deemed to be the kind and amount so receivable per share by a plurality of the Non-Electing Shares). Such supplemental indenture shall provide for adjustments which shall be as nearly equivalent as may be practicable to the adjustments provided for in this Article 12. If, in the case of any such reclassification, change, merger, consolidation, statutory share exchange, combination, sale or conveyance, the stock or other securities and assets receivable thereupon by a holder of shares of Common Stock includes shares of stock or other securities and assets of a corporation other than the successor or purchasing corporation, as the case may be, in such reclassification, change, merger, consolidation, statutory share exchange, combination, sale or conveyance, then such supplemental indenture shall also be executed by such other corporation and shall contain such additional provisions to protect the interests of the Holders of the Securities as the Board of Directors shall reasonably consider necessary by reason of the foregoing, including to the extent practicable the provisions providing for the Repurchase Rights set forth in Article 11 hereof. The Company shall cause notice of the execution of such supplemental indenture to be mailed to each Holder, at the address of such Holder as it appears on the Register, within 20 days after execution thereof. Failure to deliver such notice shall not affect the legality or validity of such supplemental indenture. The above provisions of this Section shall similarly apply to successive reclassifications, mergers, consolidations, statutory share exchanges, combinations, sales and conveyances. If this Section 12.11 applies to any event or occurrence, Section 12.4 hereof shall not apply. SECTION 12.12 RESPONSIBILITY OF TRUSTEE FOR CONVERSION PROVISIONS. The Trustee, subject to the provisions of Section 5.1 hereof, and any Conversion Agent shall not at any time be under any duty or responsibility to any Holder of Securities to determine whether any facts exist which may require any adjustment of the Conversion Price, or with respect to the nature or intent of any such adjustments when made, or with respect to the method employed, or herein or in any supplemental indenture provided to be employed, in making the same. Neither the Trustee, subject to the provisions of Section 5.1 hereof, nor any Conversion Agent shall be accountable with respect to the validity or value (of the kind or amount) of any Common Stock, or of any other securities or property, which may at any time be issued or delivered upon the conversion of any Security; and it or they do not make any representation with respect thereto. Neither the Trustee, subject to the provisions of Section 5.1 hereof, nor any Conversion Agent shall be responsible for any failure of the Company to make any cash payment or to issue, transfer or deliver any shares of stock or share certificates or other securities or property upon the surrender of any Security for the purpose of conversion; and the Trustee, subject to the provisions of Section 5.1 hereof, and any Conversion Agent shall not be 81 responsible or liable for any failure of the Company to comply with any of the covenants of the Company contained in this Article. 82 ARTICLE 13 SUBORDINATION SECTION 13.1 SECURITIES SUBORDINATED TO SENIOR DEBT. The Company covenants and agrees, and each Holder of Securities, by such Holder's acceptance thereof, likewise covenants and agrees, that the Indebtedness represented by the Securities and the payment of the principal of and premium, if any, and interest (including Liquidated Damages, if any) on each and all of the Securities is hereby expressly subordinated and junior, to the extent and in the manner set forth and as set forth in this Section 13.1, in right of payment to the prior payment in full of all Senior Debt. (a) In the event of any distribution of assets of the Company upon any dissolution, winding up, liquidation or reorganization of the Company, whether in bankruptcy, insolvency, reorganization or receivership proceedings or upon an assignment for the benefit of creditors or any other marshalling of the assets and liabilities of the Company or otherwise, the holders of all Senior Debt shall first be entitled to receive payment of the full amount due thereon in respect of all such Senior Debt and all other amounts due or provision shall be made for such amount in cash, or other payments satisfactory to the holders of Senior Debt, before the Holders of any of the Securities are entitled to receive any payment or distribution of any character, whether in cash, securities or other property, on account of the principal of or premium, if any, or interest (including Liquidated Damages, if any) on the Indebtedness evidenced by the Securities. (b) In the event of any acceleration of Maturity of the Securities because of an Event of Default, unless the full amount due in respect of all Senior Debt is paid in cash or other form of payment satisfactory to the holders of Senior Debt, no payment shall be made by the Company with respect to the principal of, premium, if any, or interest (including Liquidated Damages, if any) on the Securities or to acquire any of the Securities (including any redemption, conversion or cash repurchase pursuant to the exercise of the Repurchase Right), and the Company shall give prompt written notice of such acceleration to such holders of Senior Debt. (c) In the event of and during the continuance of any default in payment of the principal of or premium, if any, or interest on, rent or other payment obligation in respect of, any Senior Debt, unless all such payments due in respect of such Senior Debt have been paid in full in cash or other payments satisfactory to the holders of Senior Debt, no payment shall be made by the Company with respect to the principal of, premium, if any, or interest (including Liquidated Damages, if any) on the Securities or to acquire any of the Securities (including any redemption, conversion or cash repurchase pursuant to the exercise of the Repurchase Right). The Company shall give prompt written notice to the Trustee of any default under any Senior Debt or under any agreement pursuant to which Senior Debt may have been issued. (d) During the continuance of any event of default with respect to any Designated Senior Debt, as such event of default is defined under any such Designated Senior Debt or in any agreement pursuant to which any Designated Senior Debt has been issued (other than a default in payment of the principal of or premium, if any, or interest on, rent or other payment obligation in respect of any Designated Senior Debt), permitting the holder or holders of such Designated 83 Senior Debt to accelerate the maturity thereof (or in the case of any lease, permitting the landlord either to terminate the lease or to require the Company to make an irrevocable offer to terminate the lease following an event of default thereunder), no payment shall be made by the Company, directly or indirectly, with respect to principal of, premium, if any, or interest (including Liquidated Damages, if any) on the Securities for 179 days following notice in writing (a "Payment Blockage Notice") to the Company, from any holder or holders of such Designated Senior Debt or their representative or representatives or the trustee or trustees under any indenture or under which any instrument evidencing any such Designated Senior Debt may have been issued, that such an event of default has occurred and is continuing, unless such event of default has been cured or waived or such Designated Senior Debt has been paid in full; provided, however, if the maturity of such Designated Senior Debt is accelerated (or in the case of any lease, as a result of such event of default, the landlord under the lease has given the Company notice of its intention to terminate the lease or to require the Company to make an irrevocable offer to terminate the lease), no payment may be made on the Securities until such Designated Senior Debt has been paid in full in cash or other payment satisfactory to the holders of such Designated Senior Debt or such acceleration (or termination, in the case of a lease) has been cured or waived. For purposes of this Section 13.1(d), such Payment Blockage Notice shall be deemed to include notice of all other events of default under such indenture or instrument which are continuing at the time of the event of default specified in such Payment Blockage Notice. The provisions of this Section 13.1(d) shall apply only to one such Payment Blockage Notice given in any period of 365 days with respect to any issue of Designated Senior Debt, and no such continuing event of default that existed or was continuing on the date of delivery of any Payment Blockage Notice shall be, or shall be made, the basis for a subsequent Payment Blockage Notice. (e) In the event that, notwithstanding the foregoing provisions of Sections 13.1(a), 13.1(b), 13.1(c) and 13.1(d), any payment on account of principal, premium, if any, or interest (including Liquidated Damages, if any) on the Securities shall be made by or on behalf of the Company and received by the Trustee, by any Holder or by any Paying Agent (or, if the Company is acting as its own Paying Agent, money for any such payment shall be segregated and held in trust): (i) after the occurrence of an event specified in Section 13.1(a) or 13.1(b), then, unless all Senior Debt is paid in full in cash, or provision shall be made therefor, (ii) after the happening of an event of default of the type specified in Section 13.1(c) above, then, unless the amount of such Senior Debt then due shall have been paid in full, or provision made therefor or such event of default shall have been cured or waived, or (iii) after the happening of an event of default of the type specified in Section 13.1(d) above and delivery of a Payment Blockage Notice, then, unless such event of default shall have been cured or waived or the 179-day period specified in Section 13.1(d) shall have expired, 84 such payment (subject, in each case, to the provisions of Section 13.7 hereof) shall be held in trust for the benefit of, and shall be immediately paid over to, the holders of Designated Senior Debt (unless an event described in Section 13.1(a), (b) or (c) has occurred, in which case the payment shall be held in trust for the benefit of, and shall be immediately paid over to all holders of Senior Debt) or their representative or representatives or the trustee or trustees under any indenture under which any instruments evidencing any of the Designated Senior Debt or Senior Debt, as the case may be, may have been issued, as their interests may appear. SECTION 13.2 SUBROGATION. Subject to the payment in full of all Senior Debt to which the Indebtedness evidenced by the Securities is in the circumstances subordinated as provided in Section 13.1 hereof, the Holders of the Securities shall be subrogated to the rights of the holders of such Senior Debt to receive payments or distributions of cash, property or securities of the Company applicable to such Senior Debt until all amounts owing on the Securities shall be paid in full, and, as between the Company, its creditors other than holders of such Senior Debt, and the Holders of the Securities, no such payment or distribution made to the holders of Senior Debt by virtue of this Article which otherwise would have been made to the holders of the Securities shall be deemed to be a payment by the Company on account of such Senior Debt, provided that the provisions of this Article are and are intended solely for the purpose of defining the relative rights of the Holders of the Securities, on the one hand, and the holders of Senior Debt, on the other hand. SECTION 13.3 OBLIGATION OF THE COMPANY IS ABSOLUTE AND UNCONDITIONAL. Nothing contained in this Article or elsewhere in this Indenture or in the Securities is intended to or shall impair, as between the Company, its creditors other than the holders of Senior Debt, and the Holders of the Securities, the obligation of the Company, which is absolute and unconditional, to pay to the Holders of the Securities the principal of and premium, if any, and interest (including Liquidated Damages, if any) on the Securities as and when the same shall become due and payable in accordance with their terms, or is intended to or shall affect the relative rights of the Holders of the Securities and creditors of the Company other than the holders of Senior Debt, nor shall anything contained herein or therein prevent the Trustee or the Holder of any Security from exercising all remedies otherwise permitted by applicable law upon default under this Indenture, subject to the rights, if any, under this Article of the holders of Senior Debt in respect of cash, property or securities of the Company received upon the exercise of any such remedy. SECTION 13.4 MATURITY OF OR DEFAULT ON SENIOR DEBT. Upon the maturity of any Senior Debt by lapse of time, acceleration or otherwise, all principal of or premium, if any, or interest on, rent or other payment obligations in respect of all such matured Senior Debt shall first be paid in full, or such payment shall have been duly provided for, before any payment on account of principal, or premium, if any, or interest (including Liquidated Damages, if any) is made upon the Securities. 85 SECTION 13.5 PAYMENTS ON SECURITIES PERMITTED. Except as expressly provided in this Article, nothing contained in this Article shall affect the obligation of the Company to make, or prevent the Company from making, payments of the principal of, or premium, if any, or interest (including Liquidated Damages, if any) on the Securities in accordance with the provisions hereof and thereof, or shall prevent the Trustee or any Paying Agent from applying any moneys deposited with it hereunder to the payment of the principal of, or premium, if any, or interest (including Liquidated Damages, if any) on the Securities. SECTION 13.6 EFFECTUATION OF SUBORDINATION BY TRUSTEE. Each Holder of Securities, by such Holder's acceptance thereof, authorizes and directs the Trustee on such Holder's behalf to take such action as may be necessary or appropriate to effectuate the subordination provided in this Article and appoints the Trustee such Holder's attorney-in-fact for any and all such purposes. Upon any payment or distribution of assets of the Company referred to in this Article, the Trustee and the Holders of the Securities shall be entitled to rely upon any order or decree made by any court of competent jurisdiction in which any such dissolution, winding up, liquidation or reorganization proceeding affecting the affairs of the Company is pending or upon a certificate of the trustee in bankruptcy, receiver, assignee for the benefit of creditors, liquidating trustee or agent or other Person making any payment or distribution, delivered to the Trustee or to the Holders of the Securities, for the purpose of ascertaining the Persons entitled to participate in such payment or distribution, and as to other facts pertinent to the right of such Persons under this Article, and if such evidence is not furnished, the Trustee may defer any payment to such Persons pending judicial determination as to the right of such Persons to receive such payment. SECTION 13.7 KNOWLEDGE OF TRUSTEE. Notwithstanding the provision of this Article or any other provisions of this Indenture, the Trustee shall not be charged with knowledge of the existence of any Senior Debt, of any default in payment of principal of, premium, if any, or interest on, rent or other payment obligation in respect of any Senior Debt, or of any facts which would prohibit the making of any payment of moneys to or by the Trustee, or the taking of any other action by the Trustee, unless a Responsible Officer of the Trustee having responsibility for the administration of the trust established by this Indenture shall have received written notice thereof from the Company, any Holder of Securities, any Paying or Conversion Agent of the Company or the holder or representative of any class of Senior Debt, and, prior to the receipt of any such written notice, the Trustee shall be entitled in all respects to assume that no such default or facts exist; provided, however, that unless on the third Business Day prior to the date upon which by the terms hereof any such moneys may become payable for any purpose the Trustee shall have received the notice provided for in this Section 13.7, then, anything herein contained to the contrary notwithstanding, the Trustee shall have full power and authority to receive such moneys and apply the same to the purpose for which they were received, and shall not be affected by any notice to the contrary which may be received by it on or after such date. 86 SECTION 13.8 TRUSTEE'S RELATION TO SENIOR DEBT. The Trustee shall be entitled to all the rights set forth in this Article with respect to any Senior Debt at the time held by it, to the same extent as any other holder of Senior Debt and nothing in this Indenture shall deprive the Trustee of any of its rights as such holder. Nothing contained in this Article shall apply to claims of or payments to the Trustee under or pursuant to Section 5.8 hereof. With respect to the holders of Senior Debt, the Trustee undertakes to perform or to observe only such of its covenants and obligations as are specifically set forth in this Article, and no implied covenants or obligations with respect to the holders of Senior Debt shall be read into this Indenture against the Trustee. The Trustee shall not be deemed to owe any fiduciary duty to the holders of Senior Debt and the Trustee shall not be liable to any holder of Senior Debt if it shall pay over or deliver to Holders, the Company or any other Person moneys or assets to which any holder of Senior Debt shall be entitled by virtue of this Article or otherwise. SECTION 13.9 RIGHTS OF HOLDERS OF SENIOR DEBT NOT IMPAIRED. No right of any present or future holder of any Senior Debt to enforce the subordination herein shall at any time or in any way be prejudiced or impaired by any act or failure to act on the part of the Company or by any noncompliance by the Company with the terms, provisions and covenants of this Indenture, regardless of any knowledge thereof any such holder may have or be otherwise charged with. SECTION 13.10 MODIFICATION OF TERMS OF SENIOR DEBT. Any renewal or extension of the time of payment of any Senior Debt or the exercise by the holders of Senior Debt of any of their rights under any instrument creating or evidencing Senior Debt, including without limitation the waiver of default thereunder, may be made or done all without notice to or assent from the Holders of the Securities or the Trustee. No compromise, alteration, amendment, modification, extension, renewal or other change of, or waiver, consent or other action in respect of, any liability or obligation under or in respect of, or of any of the terms, covenants or conditions of any indenture or other instrument under which any Senior Debt is outstanding or of such Senior Debt, whether or not such release is in accordance with the provisions or any applicable document, shall in any way alter or affect any of the provisions of this Article or of the Securities relating to the subordination thereof. SECTION 13.11 CERTAIN CONVERSIONS NOT DEEMED PAYMENT. For the purposes of this Article 13 only: (1) the issuance and delivery of junior securities upon conversion of Securities in accordance with Article 12 hereof shall not be deemed to constitute a payment or distribution on account of the principal of, premium, if any, or interest (including Liquidated Damages, if any) on Securities or on account of the purchase or other acquisition of Securities, and 87 (2) the payment, issuance or delivery of cash (except in satisfaction of fractional shares pursuant to Section 12.3 hereof), property or securities (other than junior securities) upon conversion of a Security shall be deemed to constitute payment on account of the principal of, premium, if any, or interest (including Liquidated Damages, if any) on such Security. For the purposes of this Section 13.11, the term "junior securities" means: (a) shares of any common stock of the Company or (b) other securities of the Company that are subordinated in right of payment to all Senior Debt that may be outstanding at the time of issuance or delivery of such securities to substantially the same extent as, or to a greater extent that, the Securities are so subordinated as provided in this Article. Nothing contained in this Article 13 or elsewhere in this Indenture or in the Securities is intended to or shall impair, as among the Company, its creditors (other than holders of Senior Debt) and the Holders of Securities, the right, which is absolute and unconditional, of the Holder of any Security to convert such Security in accordance with Article 12 hereof. 88 ARTICLE 14 OTHER PROVISIONS OF GENERAL APPLICATION SECTION 14.1 TRUST INDENTURE ACT CONTROLS.

Principal and Interest. Inhale Therapeutic Systems, Inc., a Delaware corporation (the "Company") promises to pay interest on the principal amount of this Security at the Interest Rate from the date of issuance until repayment at Maturity, redemption or repurchase. The Company will pay interest on this Security semiannually in arrears on April 17 and October 17 of each year (each an "Interest Payment Date"), commencing April 17, 2001. Interest on the Securities shall be computed (i) for any full semiannual period for which a particular Interest Rate is applicable on the basis of a 360-day year of twelve 30-day months and (ii) for any period for which a particular Interest Rate is applicable shorter than a full semiannual period for which interest is calculated, on the basis of a 30-day month and, for such periods of less than a month, the actual number of days elapsed over a 30-day month. A Holder of any Security at the close of business on a Regular Record Date shall be entitled to receive interest on such Security on the corresponding Interest Payment Date. A Holder of any Security which is converted after the close of business on a Regular Record Date and prior to the corresponding Interest Payment Date (other than any Security whose Maturity is prior to such Interest Payment Date) shall be entitled to receive interest on the principal amount of such Security, notwithstanding the conversion of such Security prior to such Interest Payment Date. However, any such Holder which surrenders any such Security for conversion during the period between the close of business on such Regular Record Date and ending with the opening of business on the corresponding Interest Payment Date shall be required to pay the Company an amount equal to the interest on the principal amount of such Security so converted, which is payable by the Company to such Holder on such Interest Payment Date, at the time such Holder surrenders such Security for conversion. Notwithstanding the foregoing, any such Holder which surrenders for conversion any Security which has been called for redemption by the Company in a notice of redemption given by the Company pursuant to Section 10.5 of the Indenture shall be entitled to receive (and retain) such interest and need not pay the Company an amount equal to the interest on the principal amount of such Security so converted at the time such Holder surrenders such Security for conversion. In accordance with the terms of the Resale Registration Rights Agreement, dated October 17, 2000, between the Company and Merrill Lynch, Pierce, Fenner & Smith Incorporated, Deutsche Bank Securities Inc., Lehman Brothers Inc. and U.S. Bancorp Piper Jaffray Inc., during the first 90 days following a Registration Default (as defined in the Resale Registration Rights Agreement), the Interest Rate borne by the Securities shall be increased by 0.25% on: A-5 (A) January 17, 2001, if the shelf registration statement (the "Shelf Registration Statement") is not filed prior to or on January 16, 2001; (B) April 18, 2001, if the Shelf Registration Statement is not declared effective by the Securities and Exchange Commission prior to or on April 17, 2001; (C) the day after the fifth Business Day after the Shelf Registration Statement, previously declared effective, ceases to be effective or fails to be usable, if a post-effective amendment (or report filed pursuant to the Exchange Act) that cures the Shelf Registration Statement is not filed with the Securities and Exchange Commission during such five Business Day period; or (D) the day following the 45th or 60th day, as the case may be, of any period that the prospectus contained in the Shelf Registration Statement has been suspended, if such suspension has not been terminated. From and after the 91st day following such Registration Default, the Interest Rate borne by the Securities shall be increased by 0.50%. In no event shall the Interest Rate borne by the Securities be increased by more than 0.50%. Any amount of additional interest will be payable in cash semiannually, in arrears, on each Interest Payment Date and will cease to accrue on the date the Registration Default is cured. The Holder of this Security is entitled to the benefits of the Resale Registration Rights Agreement. 2. Method of Payment. Interest on any Security which is payable, and is punctually paid or duly provided for, on any Interest Payment Date shall be paid to the person in whose name that Security (or one or more Predecessor Securities) is registered at the close of business on the Regular Record Date for such interest. Principal of, and premium, if any, and interest on, Global Securities will be payable to the Depositary in immediately available funds. Principal and premium, if any, on Physical Securities will be payable at the office or agency of the Company maintained for such purpose, initially the Corporate Trust Office of the Trustee. Interest on Physical Securities will be payable by (i) U.S. Dollar check drawn on a bank in The City of New York mailed to the address of the Person entitled thereto as such address shall appear in the Register, or (ii) upon application to the Registrar not later than the relevant Record Date by a Holder of an aggregate principal amount in excess of $5,000,000, wire transfer in immediately available funds. 3. Paying Agent and Registrar. Initially, Chase Manhattan Bank and Trust Company, National Association, the Trustee under the Indenture, will act as Paying Agent and Registrar. The Company may change the Paying Agent or Registrar without notice to any Holder. A-6 4. Indenture. The Company issued this Security under an Indenture, dated as of October 17, 2000 (the "Indenture"), between the Company and Chase Manhattan Bank and Trust Company, National Association, as trustee (the "Trustee"). The terms of the Security include those stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act of 1939, as amended ("TIA"). This Security is subject to all such terms, and Holders are referred to the Indenture and the TIA for a statement of all such terms. To the extent permitted by applicable law, in the event of any inconsistency between the terms of this Security and the terms of the Indenture, the terms of the Indenture shall control. 5. Provisional Redemption. The Securities may be redeemed at the election of the Company, as a whole or from time to time in part or any date, at any time prior to October 17, 2003 (a "Provisional Redemption"), at a Redemption Price equal to $1,000 per $1,000 principal amount of the Securities, on the date of redemption (the "Provisional Redemption Date") if (i) the Closing Price of the Common Stock has exceeded 150% of the Conversion Price (as may be adjusted from time to time) then in effect for at least 20 Trading Days in any consecutive 30 Trading Day period ending on the Trading Day prior to the date of mailing of the provisional notice of redemption upon not less than 20 nor more than 60 days notice (the "Notice Date'), and (ii) a registration statement covering resales of the Securities and Common Stock issuable upon the conversion thereof is effective and available for use and is expected to remain effective for the 30 days following the Provisional Redemption Date. Upon any such Provisional Redemption, the Company shall make an additional payment (the "Make-Whole Payment") with respect to the Securities called for redemption to Holders on the Notice Date in an amount equal to $105.00 per $1,000 principal amount of the Securities, less the amount of any interest actually paid on such Securities prior to the Provisional Redemption Date. The Company shall make the Make-Whole Payment on all Securities called for Provisional Redemption, including those Securities converted into Common Stock between the Notice Date and the Provisional Redemption Date. The Company may elect to pay the Make-Whole Payment or any portion thereof (i) in cash or, (ii) subject to the fulfillment by the Company of the conditions set forth in Section 10.1 of the Indenture, by delivering the number of shares of Common Stock equal to (x) the Make-Whole Payment (or any portion thereof that the Company elects to pay in shares of Common Stock) divided by (y) 97% of the average of the Closing Prices per share of Common Stock for the five consecutive Trading Days immediately preceding and including the first Trading Day prior to the Provisional Redemption Date. 6. Optional Redemption. Except as provided above, this Security is not redeemable prior to October 17, 2003. This Security may be redeemed in whole or in part, upon not less than 20 nor more than 60 days' notice, at any time on or after October 17, 2003, at the option of the Company, at the Redemption Prices (expressed as percentages of the principal amount) set forth below if A-7 redeemed during the 12-month period beginning October 17 of the years indicated and ending October 16 of the following years, plus any interest accrued but not paid prior to the Optional Redemption Date, if the Closing Price of the Common Stock has exceeded 120% of the Conversion Price (as defined in Article 12 of the Indenture and as such may be adjusted from time to time) then in effect for at least 20 Trading Days in any consecutive 30 Trading Day period ending on the Trading Day immediately prior to the date of mailing of the notice of optional redemption pursuant to Section 10.5 of the Indenture, plus any interest accrued but unpaid to the Redemption Date.
DURING THE TWELVE MONTHS COMMENCING REDEMPTION PRICES ------------------------ ----------------- October 17, 2003.............................................. 102.00% October 17, 2004.............................................. 101.50% October 17, 2005.............................................. 101.00% October 17, 2006.............................................. 100.50%
Securities in original denominations larger than $1,000 may be redeemed in part. If any Security selected for partial redemption is converted in part before termination of the conversion right with respect to the portion of the Security so selected, the converted portion of such Security shall be deemed to be the portion selected for redemption (provided, however, that the Holder of such Security so converted and deemed redeemed shall not be entitled to any additional interest payment as a result of such deemed redemption than such Holder would have otherwise been entitled to receive upon conversion of such Security). Securities which have been converted during a selection of Securities to be redeemed may be treated by the Trustee as Outstanding for the purpose of such selection. On and after the Redemption Date, interest ceases to accrue on Securities or portions of Securities called for redemption, unless the Company defaults in the payment of the Redemption Price and accrued and unpaid interest. Notice of redemption will be given by the Company to the Holders as provided in the Indenture. 7. Repurchase Right Upon a Change of Control. If a Change in Control occurs, the Holder of Securities, at the Holder's option, shall have the right, in accordance with the provisions of the Indenture, to require the Company to repurchase the Securities (or any portion of the principal amount hereof that is at least $1,000 or an integral multiple thereof, provided that the portion of the principal amount of this Security to be Outstanding after such repurchase is at least equal to $1,000) at the Repurchase Price in cash, plus any interest accrued and unpaid to the Repurchase Date. A-8 Subject to the conditions provided in the Indenture, the Company may elect to pay the Repurchase Price by delivering a number of shares of Common Stock equal to (i) the Repurchase Price divided by (ii) 95% of the average of the Closing Prices per share for the five consecutive Trading Days immediately preceding and including the third Trading Day prior to the Repurchase Date. No fractional shares of Common Stock will be issued upon repurchase of any Securities. Instead of any fractional share of Common Stock which would otherwise be issued upon conversion of such Securities, the Company shall pay a cash adjustment as provided in the Indenture. A Company Notice will be given by the Company to the Holders as provided in the Indenture. To exercise a repurchase right, a Holder must deliver to the Trustee a written notice as provided in the Indenture. 8. Conversion Rights. Subject to and upon compliance with the provisions of the Indenture, the Holder of Securities is entitled, at such Holder's option, at any time before the close of business on October 17, 2007, to convert the Holder's Securities (or any portion of the principal amount hereof which is $1,000 or an integral multiple thereof), at the principal amount thereof or of such portion, into duly authorized, fully paid and nonassessable shares of Common Stock of the Company at the Conversion Price in effect at the time of conversion. In the case of a Security (or a portion thereof) called for redemption, such conversion right in respect of the Security (or such portion thereof) so called, shall expire at the close of business on the second Business Day preceding the Redemption Date, unless the Company defaults in making the payment due upon redemption. In the case of a Change of Control for which the Holder exercises its Repurchase Right with respect to a Security (or a portion thereof), such conversion right in respect of the Security (or portion thereof) shall expire at the close of business on the Business Day preceding the Repurchase Date. The Conversion Price shall be initially equal to $50.46 per share of Common Stock. The Conversion Price shall be adjusted under certain circumstances as provided in the Indenture. To exercise the conversion right, the Holder must surrender the Security (or portion thereof) duly endorsed or assigned to the Company or in blank, at the office of the Conversion Agent, accompanied by a duly signed conversion notice to the Company. Any Security surrendered for conversion during the period from the close of business on any Regular Record Date to the opening of business on the corresponding Interest Payment Date (other than any Security whose Maturity is prior to such Interest Payment Date), shall also be accompanied by payment in New York Clearing House funds or other funds acceptable to the Company of an amount equal to the interest payable on such Interest Payment Date on the principal amount of the Securities being surrendered for conversion. No fractional shares of Common Stock will be issued upon conversion of any Securities. Instead of any fractional share of Common Stock which would otherwise be issued upon conversion of such Securities, the Company shall pay a cash adjustment as provided in the Indenture. 9. Subordination. The Indebtedness evidenced by this Security is, to the extent and in the manner provided in the Indenture, subordinated and subject in right of payment to the prior payment in full of all A-9 amounts then due on all Senior Debt of the Company, and this Security is issued subject to such provisions of the Indenture with respect thereto. Each Holder of this Security, by accepting the same, (a) agrees to and shall be bound by such provisions, (b) authorizes and directs the Trustee on such Holder's behalf to take such action as may be necessary or appropriate to effectuate the subordination so provided and (c) appoints the Trustee such Holder's attorney-in-fact for any and all such purposes. 10. Denominations; Transfer; Exchange. The Securities are issuable in registered form, without coupons, in denominations of $1,000 and integral multiples of $1,000 in excess thereof. A Holder may register the transfer or exchange of Securities in accordance with the Indenture. The Registrar may require a Holder, among other things, to furnish appropriate endorsements and transfer documents and the Company may require a Holder to pay any taxes and fees required by law or permitted by the Indenture. In the event of a redemption in part, the Company will not be required (a) to register the transfer of, or exchange, Securities for a period of 15 days immediately preceding the date notice is given identifying the serial numbers of the Securities called for such redemption, or (b) to register the transfer of, or exchange, any such Securities, or portion thereof, called for redemption. In the event of redemption, conversion or repurchase of the Securities in part only, a new Security or Securities for the unredeemed, unconverted or unrepurchased portion thereof will be issued in the name of the Holder hereof. 11. Persons Deemed Owners. The registered Holder of this Security shall be treated as its owner for all purposes. 12. Unclaimed Money. The Trustee and the Paying Agent shall pay to the Company any money held by them for the payment of principal, premium, if any, or interest that remains unclaimed for two years after the date upon which such payment shall have become due. After payment to the Company, Holders entitled to the money must look to the Company for payment as general creditors unless an applicable abandoned property law designates another Person, and all liability of the Trustee and such Paying Agent with respect to such money shall cease. 13. Discharge Prior to Redemption or Maturity. Subject to certain conditions contained in the Indenture, the Company may discharge its obligations under the Securities and the Indenture if (1) (a) all of the Outstanding Securities shall become due and payable at their scheduled Maturity within one year or (b) all of the Outstanding Securities are scheduled for redemption within one year, and (2) the Company shall have deposited with the Trustee money and/or U.S. Government Obligations sufficient to pay the principal of, and premium, if any, and interest on, all of the Outstanding Securities on the date of Maturity or redemption, as the case may be. A-10 14. Amendment; Supplement; Waiver. The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the rights of the Holders of the Securities under the Indenture at any time by the Company and the Trustee with the consent of the Holders of a majority in aggregate principal amount of the Outstanding Securities (or such lesser amount as shall have acted at a meeting pursuant to the provisions of the Indenture). The Indenture also contains provisions permitting the Holders of specified percentages in principal amount of the Securities at the time Outstanding, on behalf of the Holders of all the Securities, to waive compliance by the Company with certain provisions of the Indenture and certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Security shall be conclusive and binding upon such Holder and upon all future Holders of this Security and of any Security issued upon registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Security or such other Security. No reference herein to the Indenture and no provision of this Security or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of and premium, if any, and interest (including Liquidated Damages, if any) on this Security at the times, places and rate, and in the coin or currency, herein prescribed or to convert this Security (or pay cash in lieu of conversion) as provided in the Indenture. 15. Defaults and Remedies. The Indenture provides that an Event of Default with respect to the Securities occurs when any of the following occurs: (a) the Company defaults in the payment of the principal of or premium, if any, on any of the Securities when it becomes due and payable at Maturity, upon redemption or exercise of a Repurchase Right or otherwise, whether or not such payment is prohibited by the subordination provisions of Article 13 of the Indenture; (b) the Company defaults in the payment of interest on any of the Securities when it becomes due and payable and such default continues for a period of 30 days, whether or not such payment is prohibited by the subordination provisions of Article 13 of the Indenture; (c) the Company fails to perform or observe any other term, covenant or agreement contained in the Securities or the Indenture and such default continues for a period of 60 days after written notice of such failure is given as specified in the Indenture; (d) (i) the Company fails to make any payment by the end of the applicable grace period, if any, after the maturity of any Indebtedness for borrowed money in an amount in excess of $5,000,000 (provided that such failure shall not constitute an Event of Default if (1) the Company determines, in good faith, that a lessor under a lease described in clause (3)(a) of the definition of Indebtedness set forth in the Indenture breached a covenant under the lease and the Company has given notice of the A-11 breach to the lessor and the Trustee and (2) as a result of the breach, the Company withholds payment under the lease) (a "Default Exception"), or (ii) there is an acceleration of any Indebtedness for borrowed money in an amount in excess of $5,000,000 because of a default with respect to such Indebtedness (other than a Default Exception) without such Indebtedness having been discharged or such acceleration having been cured, waived, rescinded or annulled, in the case of either clause (i) or (ii) above, for a period of 30 days after written notice is given to the Company as specified in the Indenture; and (e) there are certain events of bankruptcy, insolvency or reorganization of the Company. If an Event of Default shall occur and be continuing, the principal of all the Securities may be declared due and payable in the manner and with the effect provided in the Indenture. 16.

Registration Statement on Form S-3 on or about January 12, 2001 (the
"Registration Statement") with the Securities and Exchange Commission covering
the offering of up to $230,000,000 aggregate principal amount of 3.5%
Convertible Subordinated Notes due October 17, 2007 (the "Notes") and 4,558,065
shares of the Company's Common Stock, $.0001 par value issuable upon conversion
of the Notes (the "Shares" and together with the Notes, the "Securities").

In connection with this opinion, we have examined the Registration Statement and
related Prospectus, your Certificate of Incorporation and Bylaws, as amended,
and such other documents, records, certificates, memoranda and other instruments
as we deem necessary as a basis for this opinion. We have assumed the
genuineness and authenticity of all documents submitted to us as originals, the
