PROXY STATEMENT
FOR THE 2004 ANNUAL MEETING OF STOCKHOLDERS
JUNE 17, 2004

QUESTIONS AND ANSWERS ABOUT THIS PROXY MATERIAL AND VOTING

WHY AM I RECEIVING THESE MATERIALS?

We sent you this proxy statement and the enclosed proxy card because the board of directors of Nektar Therapeutics is soliciting your proxy to vote at the 2004 annual meeting of stockholders. We invite you to attend the annual meeting to vote on the proposals described in this proxy statement. However, you do not need to attend the meeting to vote your shares. Instead, you may simply complete, sign and return the enclosed proxy card, or follow the instructions below to submit your proxy over the telephone or on the Internet.

We intend to mail this proxy statement and accompanying proxy card on or about May 10, 2004 to all stockholders of record entitled to vote at the annual meeting.

WHO CAN VOTE AT THE ANNUAL MEETING?

Only stockholders of record at the close of business on April 19, 2004 will be entitled to vote at the annual meeting. On this record date, there were 83,518,975 shares of common stock outstanding and entitled to vote.

Stockholder of Record: Shares Registered in Your Name

If on April 19, 2004 your shares were registered directly in your name with our transfer agent, Mellon Investor Services LLC, then you are a stockholder of record. As a stockholder of record, you may vote in person at the meeting or vote by proxy. Whether or not you plan to attend the meeting, we urge you to fill out and return the enclosed proxy card or vote by proxy over the telephone or on the Internet as instructed below to ensure your vote is counted.

Beneficial Owner: Shares Registered in the Name of a Broker or Bank

If on April 19, 2004 your shares were held in an account at a brokerage firm, bank, dealer, or other similar organization, then you are the beneficial owner of shares held in "street name" and these proxy materials are being forwarded to you by that organization. The organization holding your account is considered the stockholder of record for purposes of voting at the annual meeting. As a beneficial owner, you have the right to direct your broker or other agent on how to vote the shares in your account. You are also invited to attend the annual meeting. However, since you are not the stockholder of record, you may not vote your shares in person at the meeting unless you request and obtain a valid proxy from your broker or other agent.

WHAT AM I VOTING ON?

There are three matters scheduled for a vote:

•: Election of three directors to serve until the 2007 annual meeting of stockholders;
•: Approval of a proposed 900,000 share increase in the number of shares of common stock authorized for issuance under our 2000 Equity Incentive Plan, as amended and restated (the "Plan"); and
•: Ratification of Ernst & Young LLP as our independent auditors for our fiscal year ending December 31, 2004.

HOW DO I VOTE?

You may either vote "For" all the nominees to the board of directors or you may abstain from voting for any nominee you specify. For each of the other matters to be voted on, you may vote "For" or "Against" or abstain from voting. The procedures for voting are fairly simple:

Stockholder of Record: Shares Registered in Your Name

If you are a stockholder of record, you may vote in person at the annual meeting, vote by proxy using the enclosed proxy card, vote by proxy over the telephone, or vote by proxy on the Internet. Whether or not you plan to attend the meeting, we urge you to vote by proxy to ensure your vote is counted. You may still attend the meeting and vote in person if you have already voted by proxy.

1.: To vote in person, come to the annual meeting and we will give you a ballot when you arrive.
2.: To vote using the proxy card, simply complete, sign and date the enclosed proxy card and return it promptly in the envelope provided. If you return your signed proxy card to us before the annual meeting, we will vote your shares as you direct.
3.: To vote over the telephone, dial toll-free (800) 435-6710 using a touch-tone phone and follow the recorded instructions. You will be asked to provide the company number and control number from the enclosed proxy card. Your vote must be received by 11:59 p.m., Eastern Time on June 16, 2004 to be counted.
4.: To vote on the Internet, go to www.eproxy.com/nktr to complete an electronic proxy card. You will be asked to provide the company number and control number from the enclosed proxy card. Your vote must be received by 11:59 p.m., Eastern Time on June 16, 2004 to be counted.

Beneficial Owner: Shares Registered in the Name of Broker or Bank

If you are a beneficial owner of shares registered in the name of your broker, bank, or other agent, you should have received a proxy card and voting instructions with these proxy materials from that organization rather than from us. Simply complete and mail the proxy card to ensure that your vote is counted. Alternatively, you may vote by telephone or over the Internet as instructed by your broker or bank. To vote in person at the annual meeting, you must obtain a valid proxy from your broker, bank, or other agent. Follow the instructions from your broker or bank included with these proxy materials, or contact your broker or bank to request a proxy form.

We provide Internet proxy voting to allow you to vote your shares on-line, with procedures designed to ensure the authenticity and correctness of your proxy vote instructions. However, please be aware that you must bear any costs associated with your Internet access, such as usage charges from Internet access providers and telephone companies.

HOW MANY VOTES DO I HAVE?

On each matter to be voted upon, you have one vote for each share of common stock you own as of April 19, 2004.

WHAT IF I RETURN A PROXY CARD BUT DO NOT MAKE SPECIFIC CHOICES?

If you return a signed and dated proxy card without marking any voting selections, your shares will be voted "For" the election of all three nominees for director, "For" a 900,000 share increase in the number of shares of common stock authorized for issuance under the Plan, and "For" the ratification of the audit committee's selection of Ernst & Young LLP as our independent auditors for the fiscal year ending December 31, 2004. If any other matter is properly presented at the meeting, your proxy (one of the individuals named on your proxy card) will vote your shares using his best judgment.

WHO IS PAYING FOR THIS PROXY SOLICITATION?

We will pay for the entire cost of soliciting proxies. In addition to these mailed proxy materials, our directors and employees may also solicit proxies in person, by telephone, or by other means of communication. We will not pay our directors and employees any additional compensation for soliciting proxies. We may also reimburse brokerage firms, banks and other agents for the cost of forwarding proxy materials to beneficial owners.

WHAT DOES IT MEAN IF I RECEIVE MORE THAN ONE PROXY CARD?

If you receive more than one proxy card, your shares are registered in more than one name or are registered in different accounts. Please complete, sign and return each proxy card to ensure that all of your shares are voted.

CAN I CHANGE MY VOTE AFTER SUBMITTING MY PROXY?

Yes. You can revoke your proxy at any time before the final vote at the meeting. You may revoke your proxy in any one of three ways:

1.: You may submit another properly completed proxy card with a later date.
2.: You may send a written notice that you are revoking your proxy to our Secretary, care of Nektar Therapeutics, at 150 Industrial Road, San Carlos, California 94070.
3.: You may attend the annual meeting and vote in person. Simply attending the meeting will not, by itself, revoke your proxy.

WHEN ARE STOCKHOLDER PROPOSALS DUE FOR NEXT YEAR'S ANNUAL MEETING?

To be considered for inclusion in next year's proxy materials, your proposal must be submitted in writing by January 10, 2005, to our Secretary, care of Nektar Therapeutics, 150 Industrial Road, San Carlos, California 94070. If you wish to submit a proposal that is not to be included in next year's proxy statement or nominate a director, pursuant to our bylaws you must provide specified information to us no earlier than the close of business on March 19, 2005 and no later than the close of business on April 18, 2005. You are also advised to review our bylaws, which contain additional requirements with respect to advance notice of stockholder proposals and director nominees.

HOW ARE VOTES COUNTED?

Votes will be counted by the inspector of election appointed for the meeting, who will separately count "For" and with respect to the second and third proposals, "Against" votes, abstentions and broker non-votes. Abstentions will be counted towards the vote total for each proposal, and will have the same

effect as "Against" votes for proposals 2 and 3. Broker non-votes have no effect and will not be counted towards the vote total for any proposal.

If your shares are held by your broker as your nominee (that is, in "street name"), you will need to obtain a proxy form from the institution that holds your shares and follow the instructions included on that form regarding how to instruct your broker to vote your shares. If you do not give instructions to your broker, your broker can vote your shares with respect to "discretionary" items, but not with respect to "non-discretionary" items. Discretionary items are proposals considered routine under the rules of the New York Stock Exchange on which your broker may vote shares held in street name in the absence of your voting instructions. On non-discretionary items for which you do not give your broker instructions, the shares will be treated as broker non-votes.

HOW MANY VOTES ARE NEEDED TO APPROVE EACH PROPOSAL?

•: For the election of directors, the three nominees receiving the most "For" votes (among votes properly cast in person or by proxy) will be elected. Broker non-votes will have no effect.
•: To be approved, Proposal No. 2 approving the proposed 900,000 share increase in the number of shares of common stock authorized for issuance under the Plan must receive a "For" vote from the majority of the shares present and entitled to vote either in person or by proxy. If you "Abstain" from voting, it will have the same effect as an "Against" vote. Broker non-votes will have no effect.
•: To be approved, Proposal No. 3 ratifying the audit committee's selection of Ernst & Young LLP as our independent auditors for our fiscal year ending December 31, 2004 must receive a "For" vote from the majority of the shares present and entitled to vote either in person or by proxy. If you "Abstain" from voting, it will have the same effect as an "Against" vote. Broker non-votes will have no effect.

WHAT IS THE QUORUM REQUIREMENT?

A quorum of stockholders is necessary to hold a valid meeting. A quorum will be present if at least a majority of the outstanding shares entitled to vote are represented by stockholders present at the meeting or by proxy. On the record date, there were 83,518,975 outstanding and entitled to vote.

Your shares will be counted towards the quorum only if you submit a valid proxy vote or vote at the meeting. Abstentions and broker non-votes will be counted towards the quorum requirement. If there is no quorum, the chairman of the meeting or a majority of the votes present at the meeting may adjourn the meeting to another date.

HOW CAN I FIND OUT THE RESULTS OF THE VOTING AT THE ANNUAL MEETING?

Preliminary voting results will be announced at the annual meeting. Final voting results will be published in our quarterly report on Form 10-Q for the second quarter of 2004.

PROPOSAL 1

ELECTION OF DIRECTORS

Our board of directors is divided into three classes. Each class consists, as nearly as possible, of one-third of the total number of directors, and each class has a three year term. Vacancies on the board may be filled only by persons elected by a majority of the remaining directors. A director elected by the board to fill a vacancy in a class shall serve for the remainder of the full term of that class until that director's successor is elected and qualified, including vacancies created by an increase in the number of directors.

The board of directors is presently comprised of nine members. There are three directors in the class whose term of office expires in 2004: Christopher A. Kuebler, Irwin Lerner and John S. Patton, Ph.D. Each of the nominees listed below, except for Mr. Kuebler, is currently a director of the Company who was previously elected by the stockholders. The board appointed Mr. Kuebler in December 2001. If elected at the annual meeting, each of these nominees would serve until the 2007 annual meeting and until their successors are elected and have qualified, or until the earlier of their death, resignation or removal. It is our policy to encourage all members of our board of directors and nominees recommended by the nominating and corporate governance committee to attend the annual meeting of stockholders. All of the nominees for election as a director and all other directors attended the 2003 annual meeting of stockholders.

The following is a brief biography of each nominee and each director whose term of office as a director will continue after the annual meeting.

INDEPENDENCE OF THE BOARD OF DIRECTORS

As required under the Nasdaq Stock Market, Inc. ("Nasdaq") listing standards, a majority of the members of a listed company's board of directors must qualify as "independent," as affirmatively determined by the board of directors. Our board consults with our counsel to ensure that its determinations are consistent with all relevant securities and other laws and regulations regarding the definition of "independent," including those set forth in pertinent Nasdaq listing standards, as in effect from time to time.

Consistent with these considerations, after review of all relevant transactions or relationships between each director, or any of his or her family members, and us, our senior management and our independent auditors, the board has affirmatively determined that all of our directors are independent directors within the meaning of the applicable Nasdaq listing standards, except for Mr. Chess, our Executive Chairman, Mr. Gill, our President and Chief Executive Officer and Dr. Patton, our Co-Founder and Chief Scientific Officer.

INFORMATION REGARDING THE BOARD OF DIRECTORS AND ITS COMMITTEES

In 2003, the board of directors documented the governance practices we follow by adopting our Corporate Governance Policy Statement to assure that the board will have the necessary authority and practices in place to review and evaluate our business operations as needed and to make decisions that are independent of our management. The guidelines are also intended to align the interests of directors and management with those of our stockholders. The Corporate Governance Policy Statement sets forth certain practices the board will follow with respect to board composition, board committees, board nomination, director qualifications, and evaluation of the board and committees. The board adopted the Corporate Governance Policy Statement to, among other things, reflect changes to the Nasdaq listing standards and Securities and Exchange Commission rules adopted to implement provisions of the Sarbanes-Oxley Act of 2002. The Corporate Governance Policy Statement, as well as the charters for each committee of the board, may be viewed at www.nektar.com.

As required under new Nasdaq listing standards, our independent directors will meet in regularly scheduled executive sessions at which only independent directors are present. If the chairperson of the board is independent, the chairperson will preside over such meetings. In the event that the chairperson is not independent, the lead director will preside over such meetings. If no lead director is appointed, an independent director, on a rotational basis, will serve as chairperson of such meetings, commencing with the most senior member among the independent directors.

The board has three committees: an audit committee, an organization and compensation committee, and a nominating and corporate governance committee. The following table provides membership and meeting information for fiscal year 2003 for each of the board committees:

*: Committee Chairperson
(1): Mr. Glavin resigned from our board and organization and compensation committee on December 10, 2003.
(2): Ms. Wang was elected to our board and audit committee on December 10, 2003.

Below is a description of each committee of the board of directors. The board of directors has determined that each member of each committee meets the applicable rules and regulations regarding "independence" and that each member is free of any relationship that would interfere with his or her individual exercise of independent judgment with regard to us.

AUDIT COMMITTEE

The audit committee of the board of directors oversees our corporate accounting and financial reporting process. For this purpose, the audit committee performs several functions. The audit committee evaluates the performance of and assesses the qualifications of the independent auditors; determines whether to retain or terminate the existing independent auditors or to appoint and engage new independent auditors; establishes guidelines and procedures with respect to the rotation of audit partners and other senior personnel engaged in providing audit services; reviews and approves the retention of the independent auditors for any permissible non-audit services; at least annually, discusses with the independent auditors and reviews that auditors' independence; reviews with the independent auditors any management or internal control letter issued or, to the extent practicable, proposed to be issued by the independent auditors and management's response; reviews with management and the independent auditors the scope, adequacy and effectiveness of our financial reporting controls; establishes and maintains procedures for the receipt, retention and treatment of complaints regarding accounting, internal accounting controls or auditing matters, including procedures for the confidential and anonymous submission by employees of concerns regarding questionable accounting or auditing matters; investigates and resolves any disagreements between our management and the independent auditors regarding our financial reporting, accounting practices or accounting policies; meets with senior management and the independent auditors in separate executive sessions; reviews the financial statements to be included in our Quarterly Report on Form 10-Q and our Annual Report on Form 10-K; and discusses with management and the independent auditors the results of the independent auditors' review of our quarterly financial statements and the results of our annual audit. The audit committee has the authority to retain special legal, accounting or other consultants to advise the committee as it deems necessary, at our expense, to carry out its duties and to determine the compensation of any such advisors. Four directors comprise the audit committee: Mr. Christopher A. Kuebler, Dr. Melvin Perelman, Mr. Roy A. Whitfield and Ms. Susan Wang. Ms. Wang was elected to the audit committee in December 2003. The audit committee has adopted a written audit committee charter that is attached as Appendix A to these proxy materials and is available on our corporate website at www.nektar.com.

The board of directors annually reviews the Nasdaq listing standards definition of independence for audit committee members and has determined that all members of our audit committee are independent (as independence is currently defined in Rule 4350(d)(2)(A)(i) and (ii) of the Nasdaq listing standards). The board of directors has determined that Ms. Susan Wang qualifies as an "audit committee financial expert," as defined in applicable SEC rules. The board made a qualitative assessment of Ms. Wang's level of knowledge and experience based on a number of factors, including her formal education and experience as a chief financial officer for a public reporting company. In addition to our audit committee, Ms Wang also serves on the audit committees of Avanex Corporation, Altera Corporation and Calpine Corporation. The board of directors does not believe that such simultaneous service impairs Ms. Wang's ability to effectively serve on our audit committee.

ORGANIZATION AND COMPENSATION COMMITTEE

The organization and compensation committee of the board of directors reviews management's recommendations for organization structure and development and the type and levels of compensation for our directors, officers, employees and compensation consultants, and to recommend compensation actions to the board of directors. The organization and compensation committee reviews and approves the structure and guidelines for various incentive compensation and benefit plans; reviews and approves the

qualitative criteria of the variable compensation program; grants stock options under the various incentive compensation and benefit plans; recommends to the board for approval the compensation levels for the Chairman and Chief Executive Officer and approves the compensation levels for the other executive officers and the vice presidents; recommends for the board's approval, the compensation levels for the members of the board who are outside directors; reviews on a periodic basis the operation and policies for the administration of our executive compensation programs to determine whether they remain supportive of our business objectives; and reviews management recommendations on organization structure and development. We also have an option grant subcommittee that may award stock options pursuant to our 2000 Non-Officer Equity Incentive Plan and 2000 Equity Incentive Plan. Our organization and compensation committee charter can be found on our corporate website at www.nektar.com. Two directors comprise the organization and compensation committee: Messrs. Michael A. Brown and Irwin Lerner. All members of our organization and compensation committee are independent (as independence is currently defined in Rule 4200(a)(15) of the Nasdaq listing standards).

NOMINATING AND CORPORATE GOVERNANCE COMMITTEE

The nominating and corporate governance committee of the board of directors is responsible for identifying, reviewing and recommending for the board's selection candidates to serve as directors, evaluating board composition and recommending nominations and re-election of directors, administering and overseeing all aspects of our corporate governance functions on behalf of the board, and making recommendations to the board regarding corporate governance issues. Our nominating and corporate governance committee charter can be found on our corporate website at www.nektar.com. Three directors comprise the nominating and corporate governance committee: Messrs. Michael A. Brown, Irwin Lerner, and Roy A. Whitfield. All members of the nominating and corporate governance committee are independent (as independence is currently defined in Rule 4200(a)(15) of the Nasdaq listing standards).

The nominating and corporate governance committee believes that candidates for director should possess the highest personal and professional ethics, integrity and values, be committed to represent our long-term interests and that of our shareholders, possess diverse experience at policy-making levels in business, science and technology, possess key personal characteristics such as strategic thinking, objectivity, independent judgment, intellect and the courage to speak out and actively participate in meetings as well as have sufficient time to carry out the duties and responsibilities of a board member effectively.

Candidates for director nominees are reviewed in the context of the current composition of the board, our operating requirements and the long-term interests of stockholders. In conducting this assessment, the committee considers diversity, age, skills, and such other factors as it deems appropriate given our current needs and that of our board, to maintain a balance of knowledge, experience and capability. In the case of incumbent directors whose terms of office are set to expire, the nominating and corporate governance committee reviews such directors' overall service to us during their term, including the number of meetings attended, level of participation, quality of performance, and any other relationships and transactions that might impair such directors' independence. In the case of new director candidates, the nominating and corporate governance committee also determines whether the nominee must be independent for Nasdaq purposes, which determination is based upon applicable Nasdaq listing standards, applicable SEC rules and regulations and the advice of counsel, if necessary. The committee then uses its network of contacts to compile a list of potential candidates, but may also engage, if it deems appropriate, a professional search firm. The nominating and corporate governance committee conducts any appropriate and necessary inquiries into the backgrounds and qualifications of possible candidates after considering the function and needs of the board. The nominating and corporate governance committee meets to discuss and consider such candidates' qualifications and then selects a nominee for recommendation to the board by majority vote. We have paid fees to third party search firms in the past to assist in our process of identifying or evaluating director candidates.

The nominating and corporate governance committee of our board of directors will consider for nomination any qualified director candidates recommended by our stockholders. Any stockholder who wishes to recommend a director candidate is directed to submit in writing the candidate's name, biographical information and relevant qualifications to our Secretary according to the requirements for timely submission of stockholder proposals as set forth in our bylaws. All timely submitted written submissions received from our stockholders will be reviewed by the nominating and corporate governance committee at the next appropriate meeting. The nominating and corporate governance committee will evaluate any director nominees received from our stockholders in the same manner as recommendations received from management, committee members or members of our board.

MEETINGS OF THE BOARD OF DIRECTORS

The board of directors met seven times during the last fiscal year. Each board member attended 75% or more of the aggregate of the meetings of the board and of the committees on which he or she served, held during the period for which he or she was a director or committee member, respectively.

STOCKHOLDER COMMUNICATIONS WITH THE BOARD OF DIRECTORS

The board of directors will consider any written or electronic communication from our stockholders to the board, a committee of the board or any individual director. Any stockholder who wishes to communicate to the board of directors, a committee of the board or individual director, will be directed to submit written or electronic communications to our Secretary, which shall include contact information for such stockholder. All communications from stockholders received shall be forwarded by our Secretary to the board of directors, a committee of the board or an individual director, as appropriate, by our Secretary on a periodic basis, but in any event no later than the board of director's next scheduled meeting. The board of directors, a committee of the board, or individual directors, as appropriate, will consider and review carefully any communications from stockholders forwarded by our Secretary.

CODE OF BUSINESS CONDUCT AND ETHICS

We have adopted a code of business conduct and ethics that applies to all employees, including our principal executive officer, principal financial officer, principal accounting officer or controller, or persons performing similar functions. The code of business conduct and ethics is available free of charge upon written request to: Investor Relations, Nektar Therapeutics, 150 Industrial Road, San Carlos, California 94070. If we make any substantive amendments to the code of business conduct and ethics or grant any waiver from a provision of the code to an executive officer or director, we will file a Current Report on Form 8-K.

PROPOSAL 2

APPROVAL OF THE 2000 EQUITY INCENTIVE PLAN, AS AMENDED AND RESTATED

In February 1994, the board adopted, and the shareholders subsequently approved, our 1994 Equity Incentive Plan (the "1994 Equity Incentive Plan"). The 1994 Equity Incentive Plan was an amendment and restatement of our 1992 Stock Option Plan. In March 1996, the board and shareholders approved an increase in the number of shares reserved for issuance under the 1994 Equity Incentive Plan to a total of 7,800,000 shares of common stock (as adjusted for the stock split on August 22, 2000). In April 1998, the board amended and restated the 1994 Equity Incentive Plan to increase the number of shares reserved for issuance under the 1994 Equity Incentive Plan to a total of 9,350,000 shares of common stock.

In April 2000, our 1994 Equity Incentive Plan was amended and restated in its entirety and renamed the "2000 Equity Incentive Plan." As part of such amendment, the board and stockholders approved (i) an increase in the number of shares reserved for issuance under the Plan by 1,000,000 shares to a total of 10,350,000 shares of common stock (as adjusted for the stock split on August 22, 2000); (ii) the extension of the term of the Plan from 2004 to 2010; (iii) the inclusion of provisions accelerating vesting of options upon an optionholder's death under certain circumstances; and (iv) other amendments as to bring the Plan into conformity with law and prevalent plan design terms.

Pursuant to the 2000 Equity Incentive Plan (the "Plan"), we may grant or issue incentive stock options to employees and officers and non-qualified stock options, rights to acquire restricted stock and stock bonuses to consultants, employees, officers and employee directors.

In April 2004, our board amended and restated the Plan subject to stockholder approval, to (i) increase the number of shares of common stock authorized for issuance under the Plan from a total of 10,350,000 shares to a total of 11,250,000 shares, (ii) provide that the number of shares of common stock reserved for issuance under the Plan will be reduced by 1.5 shares for each share granted pursuant to a stock bonus or restricted stock award under the Plan, (iii) provide that the maximum term of stock options granted under the Plan will be eight years, except that in certain cases, the maximum term of incentive stock options will be five years (see "Eligibility"), and (iv) provide that the exercise price of each nonstatutory stock option granted under the Plan may not be less than 100% of the fair market value of the common stock subject to the option on the date of grant. Our board adopted this amendment in order to attract and retain qualified personnel, to provide additional incentives to our employees, officers, consultants and employee directors and to promote the success of our business. In the event that this proposal is not approved by the stockholders at our 2004 annual meeting of stockholders, the proposed amendment to the Plan will not be effected and the Plan will remain in full force and effect.

As of December 31, 2003, 965,290 shares of common stock are available for future grant under the Plan. In addition, there are 4,919,891 shares of common stock issuable upon the exercise of stock options outstanding as of December 31, 2003, with a weighted average exercise price of $15.337 and a weighted average term of expiration of ten years. During the fiscal year ending December 31, 2003, we granted options under the Plan to purchase 529,875 shares of common stock at exercise prices ranging from $5.063 per share to $13.09 per share.

Stockholders are requested in this Proposal 2 to approve the increase in the number of shares of common stock authorized under the Plan. The affirmative vote of the holders of a majority of the shares present in person or represented by proxy and entitled to vote at the meeting will be required to approve the Plan, as amended. Abstentions will be counted toward the tabulation of votes cast on proposals presented to the stockholders and will have the same effect as negative votes. Broker non-votes are counted towards a quorum, but are not counted for any purpose in determining whether this matter has been approved. If stockholders fail to approve this Proposal 2, the Plan will remain as is without any changes thereto.

THE BOARD OF DIRECTORS RECOMMENDS
A VOTE "FOR" PROPOSAL 2.

The essential features of the Plan, as amended and restated, are outlined below:

PURPOSE

The purpose of the Plan is to attract and retain qualified personnel, to provide additional incentives to our employees, officers, consultants and employee directors and to promote the success of our business. The Plan provides a means by which eligible recipients may be given an opportunity to benefit from increases in value of the common stock through the granting of the following awards: (i) incentive stock options, (ii) nonstatutory stock options, (iii) stock bonuses and (iv) rights to acquire restricted stock. We currently have approximately 700 employees, including three directors who are also employees, and approximately 60 consultants who are eligible to participate in the Plan.

ADMINISTRATION

Our board of directors administers the Plan. The board has the final power to construe and interpret the Plan and, subject to the provisions of the Plan, to determine the persons to whom and the dates on which awards will be granted, whether an award granted will be an incentive stock option, a nonstatutory stock option, a stock bonus, a right to purchase restricted stock, or a combination of the foregoing, the number of shares to be subject to each award, the time or times during the term of each award within which all or a portion of such award may be exercised, the exercise price, the type of consideration and other terms of the award. The board has the power, to delegate administration of the Plan to a committee consisting solely of two or more independent directors. As used herein with respect to the Plan, the "board" refers to any committee the board appoints and to the board.

STOCK SUBJECT TO THE PLAN

Subject to this proposal, an aggregate of 11,250,000 shares of common stock is reserved for issuance under the Plan. Subject to this proposal, the number of shares of common stock reserved for issuance under the Plan will be decreased by 1.5 shares for each share granted pursuant to a stock bonus or restricted stock award under the Plan. If awards granted under the Plan expire, lapse or otherwise terminate without being exercised (or vested in the case of unvested shares), the shares of common stock not purchased under such awards again become available for issuance under the Plan.

ELIGIBILITY

Incentive stock options may be granted under the Plan only to our employees and employees of our affiliates. Consultants, employees and directors are eligible to receive other awards under the Plan.

No incentive stock option may be granted under the Plan to any person who, at the time of grant, owns (or is deemed to own) stock possessing more than 10% of the total combined voting power of us or our affiliates, unless the option exercise price is at least 110% of the fair market value of the stock subject to the option on the date of grant, and the term of the option does not exceed five years from the date of grant. For incentive stock options granted under the Plan, the aggregate fair market value, determined at the time of grant, of the shares of common stock with respect to which such options are exercisable for the first time by an optionholder during any calendar year (under all such plans of ours and our affiliates) may not exceed $100,000.

No employee may be granted options covering more than 800,000 shares of the common stock within a calendar year. The purpose of this limitation is to ensure that we generally will continue to be able to deduct for tax purposes the compensation attributable to the exercise of options granted under the Plan with an exercise price at or above the fair market value of our common stock on the date of grant. To date, we have not granted to any employee in any calendar year awards to purchase a number of shares equal to the limitation, and we do not currently have any intention of granting such number of awards to any employee. There can be no assurance, however, that the board will not determine in some future

circumstances that it would be in our best interests and the best interests of our stockholders to grant awards to purchase such number of shares to a single employee during a calendar year.

No consultant may be granted stock awards under the Plan if, at the time of grant, a Form S-8 registration statement is not available to register either the offer or the sale of our securities to the consultant because of the nature of the services provided by the consultant, or because the consultant is not a natural person or as otherwise provided by law, unless we determine that (i) such grants shall be registered in another manner under the Securities Act or does not require registration and (ii) such grant complies with the securities laws of all other relevant jurisdictions.

TERMS OF OPTIONS

The following is a description of the permissible terms of options under the Plan. Individual option grants may be more restrictive as to any or all of the permissible terms described below.

Exercise Price; Payment. The exercise price of incentive stock options under the Plan may not be less than the fair market value of the common stock subject to the option on the date of the option grant, and in some cases (see "Eligibility" above), may not be less than 110% of such fair market value. Subject to this proposal, the exercise price of nonstatutory options under the Plan may not be less than 100% of the fair market value of the common stock subject to the option on the date of the option grant. On March 31, 2004, the closing price of the common stock as reported on the Nasdaq National Market was $21.52 per share.

The exercise price of options granted under the Plan must be paid either: (a) in cash at the time the option is exercised; (b) at the discretion of the board, (i) by delivery of our common stock, or (ii) pursuant to a deferred payment arrangement; or (c) in any other form of legal consideration acceptable to the board.

Option Exercise. Options granted under the Plan may become exercisable in cumulative increments ("vest") as determined by the Board.

Options generally vest in monthly installments beginning one year from the date of grant, with the effect that such shares are fully vested after five years from the date of grant. However, if the optionholder's service to the Company and its affiliates terminates due to death, then subject to certain restrictions, the vesting of the option will accelerate.

Shares covered by options granted in the future under the Equity Incentive Plan may be subject to different vesting terms. The board has the power to accelerate the time during which an option may be exercised. In addition, options granted under the Plan may permit exercise prior to vesting, but in such event the optionholder may be required to enter into an early exercise stock purchase agreement that allows us to repurchase shares not yet vested at their exercise price should the optionholder's service to us or our affiliates end before vesting. To the extent provided by the terms of an option, an optionholder may satisfy any federal, state or local tax withholding obligation relating to the exercise of such option by a cash payment upon exercise, by authorizing the Company to withhold a portion of the stock otherwise issuable to the optionholder, by delivering already-owned stock or by a combination of these means.

Term. Subject to this proposal, the maximum term of options under the Plan is eight years, except that in certain cases (see "Eligibility") the maximum term of incentive stock options is five years. Options under the Plan generally terminate three months after termination of the optionholder's employment or relationship as a consultant or director to us or our affiliates, unless (a) such termination is due to such person's permanent and total disability (as defined in the Internal Revenue Code of 1986, as amended (the "Code"), in which case the option may, but need not, provide that it may be exercised at any time within twelve months following such termination; (b) the optionholder dies while employed by or serving a consultant or director to us or our affiliates, or within three months after termination of such relationship,

in which case the option may, but need not, provide that it may be exercised (to the extent the option was exercisable at the time of the optionholder's death) within eighteen months following the optionholder's death by the person or persons to whom the rights to such option pass by will or by the laws of descent and distribution; or (c) the option by its terms specifically provides otherwise. Individual options by their terms may provide for exercise within a longer or shorter period of time following termination of employment or the consulting relationship. The option term may also be extended in the event that exercise of the option within these periods is prohibited for specified reasons.

TERMS OF STOCK BONUSES AND PURCHASES OF RESTRICTED STOCK

Purchase Price; Payment. The purchase price under each stock purchase agreement will be determined by the board but in any event may be no less than 85% of the fair market value of our common stock on the date of grant.

The purchase price of stock pursuant to a stock purchase agreement must be paid either: (i) in cash at the time of purchase; (ii) at the discretion of the board, according to a deferred payment or other arrangement with the person to whom the common stock is sold; or (iii) in any other form of legal consideration that may be acceptable to the board in its discretion. Eligible participants may also be awarded stock pursuant to a stock bonus agreement in consideration of past services actually rendered to us for our benefit.

Repurchase. Shares of the common stock sold or awarded under the Plan may, but need not, be subject to a repurchase option in our favor in accordance with a vesting schedule determined by the board. In the event a person ceases to be an employee of or ceases to serve as a director of or consultant to us or our affiliates, we may repurchase or otherwise reacquire any or all of the shares of the common stock held by that person that have not vested as of the date of termination under the terms of the stock bonus or restricted stock purchase agreement between us and such person.

ADJUSTMENT PROVISIONS

If there is any change in the stock subject to the Plan or subject to any award granted under the Plan (through merger, consolidation, reorganization, recapitalization, stock dividend, dividend in property other than cash, stock split, liquidating dividend, combination of shares, exchange of shares, change in corporate structure or otherwise), the Plan and awards outstanding thereunder will be appropriately adjusted as to the type of security and the maximum number of shares subject to such plan and the type of security, the maximum number of shares which may be granted to an employee during a calendar year, and the type of security, number of shares and price per share of stock subject to such outstanding awards.

EFFECT OF CERTAIN CORPORATE EVENTS

In the event of our dissolution or liquidation, outstanding awards will terminate if not exercised prior to such event. In the event of a specified type of merger or corporate reorganization (a "corporate transaction"), then the surviving or acquiring corporation may assume or replace outstanding awards. If it declines to do so, the vesting and exercisability of awards held by persons whose service to us and our affiliates has not terminated will be accelerated prior to the corporate transaction, and such awards and any other outstanding awards under the Plan will terminate if not exercised prior to the corporate transaction. If there is an acquisition of majority ownership of us and such event does not constitute a corporate transaction, then the vesting and exercisability of awards held by persons whose service to us and our affiliates has not terminated also will be accelerated but outstanding awards will not terminate due to such event.

The acceleration of an award in the event of an acquisition or similar corporate event may be viewed as an anti-takeover provision, which may have the effect of discouraging a proposal to acquire or otherwise obtain control of us.

DURATION, AMENDMENT AND TERMINATION

The board may suspend or terminate the Plan without stockholder approval or ratification at any time or from time to time. The rights and obligations under any stock award granted while the Plan is in effect shall not be impaired by suspension or termination of the Plan, except with the written consent of the optionholder. Unless sooner terminated, the Plan will terminate in February 2010. The Board may also amend the Plan at any time or from time to time. However, no amendment will be effective unless approved by the stockholders of the Company to the extent stockholder approval is necessary to satisfy the requirements of Section 422 of the Code, Rule 16b-3 promulgated under the Exchange Act, other applicable law, or any Nasdaq or securities exchange listing requirements.

RESTRICTIONS ON TRANSFER

Under the Plan, an incentive stock option may not be transferred by the optionholder otherwise than by will or by the laws of descent and distribution. A nonstatutory stock option may be transferred to the extent permitted in the individual optionholder's agreement. During the lifetime of an optionholder, only the optionholder may exercise an option. No rights under a stock bonus or restricted stock purchase agreement are transferable except as expressly authorized by the terms of the applicable stock bonus or restricted stock purchase agreement. In addition, shares subject to our repurchase under an early exercise stock purchase agreement may be subject to restrictions on transfer that the board deems appropriate.

FEDERAL INCOME TAX INFORMATION

Incentive Stock Options. Incentive stock options under the Plan are intended to be eligible for the favorable federal income tax treatment accorded "incentive stock options" under the Code. There generally are no federal income tax consequences to the optionholder or to us by reason of the grant or exercise of an incentive stock option. However, the exercise of an incentive stock option may increase the optionholder's alternative minimum tax liability, if any.

If an optionholder holds stock acquired through exercise of an incentive stock option for at least two years from the date on which the option is granted and at least one year from the date on which the shares are transferred to the optionholder upon exercise of the option, any gain or loss on a disposition of such stock will be a capital gain or loss. Generally, if the optionholder disposes of the stock before the expiration of either of these holding periods (a "disqualifying disposition"), at the time of disposition, the optionholder will realize taxable ordinary income equal to the lesser of (a) the excess of the stock's fair market value on the date of exercise over the exercise price, and (b) the optionholder's actual gain, if any, on the purchase and sale. The optionholder's additional gain, or any loss, upon the disqualifying disposition will be a capital gain or loss, which will be long-term or short-term depending on the length of time that the stock was held. Capital gains currently are generally subject to lower tax rates than ordinary income. The maximum long-term capital gains rate for federal income tax purposes is currently 15% while the maximum ordinary income rate is effectively 35% at the present time. Slightly different rules may apply to optionholders who acquire stock subject to certain repurchase options or who are subject to Section 16(b) of the Exchange Act.

To the extent the optionholder recognizes ordinary income by reason of a disqualifying disposition, the Company will generally be entitled (subject to the requirement of reasonableness, the provisions of Section 162(m) of the Code and the satisfaction of a tax reporting obligation) to a corresponding business expense deduction in the tax year in which the disqualifying disposition occurs.

Nonstatutory Stock Options. Nonstatutory stock options granted under the Plan generally have the following federal income tax consequences:

There are no tax consequences to the optionholder or the Company by reason of the grant of a nonstatutory stock option. Upon exercise of a nonstatutory stock option, the optionholder normally will

recognize taxable ordinary income equal to the excess of the stock's fair market value on the date of exercise over the option exercise price. Generally, with respect to employees, we are required to withhold from regular wages or supplemental wage payments an amount based on the ordinary income recognized. Subject to the requirement of reasonableness, the provisions of Section 162(m) of the Code and the satisfaction of any tax reporting obligation, we will generally be entitled to a business expense deduction equal to the taxable ordinary income recognizable by the optionholder. Upon disposition of the stock, the optionholder will recognize a capital gain or loss equal to the difference between the selling price and the sum of the amount paid for such stock plus any amount recognized as ordinary income upon exercise of the option. Such gain or loss will be long-term or short-term depending on the length of time the stock was held.

Slightly different rules may apply to optionholders who acquire stock subject to certain repurchase options or who are subject to Section 16(b) of the Exchange Act.

Restricted Stock And Stock Bonuses. Restricted stock and stock bonuses granted under the Plan generally have the following federal income tax consequences:

Upon acquisition of stock under a restricted stock or stock bonus award, the recipient normally will recognize taxable ordinary income equal to the excess of the stock's fair market value over the purchase price, if any. However, to the extent the stock is subject to certain types of vesting restrictions, the taxable event will be delayed until the vesting restrictions lapse, unless the recipient elects to be taxed on receipt of the stock. Generally, with respect to employees, the Company is required to withhold from regular wages or supplemental wage payments an amount based on the ordinary income recognized.

Subject to the requirement of reasonableness, Section 162(m) of the Code and the satisfaction of any tax reporting obligation, the Company will generally be entitled to a business expense deduction equal to the taxable ordinary income recognizable by the recipient. Upon disposition of the stock, the recipient will recognize a capital gain or loss equal to the difference between the selling price and the sum of the amount paid for such stock, if any, plus any amount recognized as ordinary income upon acquisition (or vesting) of the stock. Such gain or loss will be long-term or short-term depending on the length of time the stock was held. Slightly different rules may apply to persons who acquire stock subject to forfeiture under Section 16(b) of the Exchange Act.

Potential Limitation On Company Deductions. As part of the Omnibus Budget Reconciliation Act of 1993, the U.S. Congress amended the Code to add Section 162(m) which denies a deduction to any publicly held corporation for compensation paid to certain employees in a taxable year to the extent that compensation exceeds $1 million for a covered employee. It is possible that compensation attributable to awards under the Plan, when combined with all other types of compensation received by a covered employee from us, may cause this limitation to be exceeded in any particular year.

Certain kinds of compensation, including qualified "performance-based compensation," are disregarded for purposes of the deduction limitation. In accordance with Treasury Regulations issued under Section 162(m) of the Code, compensation attributable to stock options will qualify as performance-based compensation, provided that: (i) the stock award plan contains a per-employee limitation on the number of shares for which stock options may be granted during a specified period; (ii) the per-employee limitation is approved by the stockholders; (iii) the award is granted by a compensation committee comprised solely of "outside directors;" and (iv) the exercise price of the award is no less than the fair market value of the stock on the date of grant. Restricted stock and stock bonuses qualify as performance-based compensation under these Treasury Regulations only if: (i) the award is granted by a compensation committee comprised solely of "outside directors;" (ii) the award is granted (or exercisable) only upon the achievement of an objective performance goal established in writing by the compensation committee while the outcome is substantially uncertain; (iii) the compensation committee certifies in writing prior to the granting (or exercisability) of the award that the performance goal has been satisfied; and (iv) prior to the granting (or exercisability) of the award, stockholders have approved the material terms of the award

(including the class of employees eligible for such award, the business criteria on which the performance goal is based, and the maximum amount (or formula used to calculate the amount) payable upon attainment of the performance goal. We have taken steps to ensure that options granted at fair market value qualify as performance-based compensation.

PROPOSAL 3

RATIFICATION OF SELECTION OF INDEPENDENT AUDITORS

The audit committee of the board of directors has selected Ernst & Young LLP as our independent auditors for the fiscal year ending December 31, 2004, and has further directed that management submit the selection of independent auditors for ratification by the stockholders at the annual meeting. Ernst & Young LLP has audited our financial statements since our inception in 1990. Representatives of Ernst & Young LLP are expected to be present at the annual meeting. They will have an opportunity to make a statement if they so desire and will be available to respond to appropriate questions.

Neither our bylaws nor other governing documents or law require stockholder ratification of the selection of Ernst & Young LLP as our independent auditors. However, the audit committee is submitting the selection of Ernst & Young LLP to the stockholders for ratification as a matter of good corporate practice. If the stockholders fail to ratify the selection, the audit committee will reconsider whether or not to retain that firm. Even if the selection is ratified, the audit committee in its discretion may direct the appointment of different independent auditors at any time during the year if they determine that such a change would be in our best interests and our stockholders' best interest.

The affirmative vote of the holders of a majority of the shares present in person or represented by proxy and entitled to vote at the annual meeting will be required to ratify the selection of Ernst & Young LLP. Abstentions will be counted toward the tabulation of votes cast on proposals presented to the stockholders and will have the same effect as negative votes. Broker non-votes are counted towards a quorum, but are not counted for any purpose in determining whether this matter has been approved.

INDEPENDENT AUDITORS' FEES

The following table represents aggregate fees billed to us for fiscal years ended December 31, 2003 and December 31, 2002, by Ernst & Young LLP, our principal accountant.

		Fiscal Year Ended
		2003		2002
Audit Fees		$	478,200	$	262,000
Audit-related Fees (includes fees for accounting research and consultation)			34,000		135,000
Tax Fees (includes fees for tax preparation and compliance)			78,500		107,000

	Total Fees	$	590,700	$	504,000

The audit committee approved all fees described above.

PRE-APPROVAL POLICIES AND PROCEDURES.

The audit committee has adopted a policy and procedures for the pre-approval of audit and non-audit services rendered by our independent auditor, Ernst & Young LLP. The policy generally pre-approves specified services in the defined categories of audit services, audit-related services, and tax services up to specified amounts. Pre-approval may also be given as part of the audit committee's approval of the scope of the engagement of the independent auditor or on an individual explicit case-by-case basis before the independent auditor is engaged to provide each service. The pre-approval of services may be delegated to one or more of the audit committee's members, but the decision must be reported to the full audit committee at its next scheduled meeting.

The audit committee has determined that the rendering of the services other than audit services by Ernst & Young LLP is compatible with maintaining the principal accountant's independence.

THE BOARD OF DIRECTORS RECOMMENDS

In April 2004, our board amended and restated the Non-Officer Plan, upon the stockholders' approval of Proposal 2 at the 2004 annual meeting of stockholders, to (i) provide that the number of shares of common stock reserved for issuance under the Non-Officer Plan will be reduced by 1.5 shares for each share granted pursuant to a stock bonus or restricted stock award under the Non-Officer Plan, (ii) provide that the maximum term of stock options granted under the Non-Officer Plan will be eight years, and (iii) provide that the exercise price of each stock option granted under the Non-Officer Plan may not be less than 100% of the fair market value of the Common Stock subject to the option on the date of grant. In the event that Proposal 2 is not approved by the stockholders at the 2004 annual meeting of stockholders, the proposed amendment to the Non-Officer Plan will not be effective. The essential features of the Non-Officer Plan, as amended and restated, are outlined below.

GENERAL

The Non-Officer Plan provides for the grant of nonstatutory stock options, stock bonuses and restricted stock purchase awards. Nonstatutory stock options granted under the Non-Officer Plan are not intended to qualify as incentive stock options under the Code. An aggregate of 12,750,000 shares of common stock are reserved for issuance under the Non-Officer Plan.

PURPOSE

The board adopted the Non-Officer Plan to provide a means by which our and our affiliates' employees and consultants who are not officers or directors may be given an opportunity to purchase our stock, to assist in retaining the services of such persons, to secure and retain the services of persons capable of filling such positions and to provide incentives for such persons to exert maximum efforts for our success and our affiliates' success.

ADMINISTRATION

The board administers the Non-Officer Plan. Subject to the provisions of the Non-Officer Plan, the board has the power to construe and interpret the Non-Officer Plan and to determine the persons to whom and the dates on which awards will be granted, the number of shares of common stock to be subject to each award, the time or times during the term of each award within which all or a portion of such award may be exercised, the exercise price, the type of consideration and other terms of the award.

The board has the power to delegate administration of the Non-Officer Plan to a committee composed of not fewer than one member of the board. As used herein with respect to the Non-Officer Plan, the "board" refers to any committee the board appoints as well as to the board itself.

STOCK SUBJECT TO THE NON-OFFICER PLAN

An aggregate of 12,750,000 shares of common stock is reserved for issuance under the Non-Officer Plan. Subject to Proposal 2, the number of shares of common stock reserved for issuance under the Non-Officer Plan will be decreased by 1.5 shares for each share granted pursuant to a stock bonus or restricted stock purchase award under the Non-Officer Plan. If awards granted under the Non-Officer Plan expire or otherwise terminate without being exercised, the shares of common stock not acquired pursuant to such awards again become available for issuance under the Non-Officer Plan. If we reacquire unvested stock issued under the Non-Officer Plan, the reacquired stock will again become available for reissuance under the Non-Officer Plan for awards.

ELIGIBILITY

Our employees and consultants, and our affiliates' employees and consultants, who are neither officers nor directors, are eligible to receive awards under the Non-Officer Plan.

TERMS OF AWARDS

Exercise Price; Payment. Subject to Proposal 2, the exercise price of options under the Non-Officer Plan may not be less than 100% of the fair market value of the common stock subject to the option on the date of the option grant. The purchase price of restricted stock purchase awards are determined by the board. Stock bonuses may be awarded in consideration for past services actually rendered to us or any of our affiliates.

The exercise price of options granted under the Non-Officer Plan must be paid either (i) in cash at the time the option is exercised, or (ii) or at the discretion of the board at the time of the grant, by delivery to us of our common stock, pursuant to a deferred payment arrangement or in any other form of legal consideration acceptable to the board. The purchase price of restricted stock purchase awards granted under the Non-Officer Plan must be paid (i) in cash at the time of purchase, (ii) at the discretion of the board, according to a deferred payment arrangement or (iii) in any other form of legal consideration acceptable to the board.

Vesting. Awards granted by the board under the Non-Officer Plan may become exercisable or released from our repurchase option in cumulative increments as determined by the board. The board has the power to accelerate the time at which an award may vest or be exercised. In addition, options granted

under the Non-Officer Plan may include an early exercise provision to permit exercise prior to vesting, but the unvested portion may be subject to our repurchase option or to any other restriction determined by the board as appropriate.

Term. The board shall have sole discretion over the term of options granted under the Non-Officer Plan, provided, however, subject to Proposal 2, the maximum term of options granted under the Non-Officer Plan is eight years. In the event that a holder's continuous service with us or an affiliate of ours terminates other than due to the death or disability of such holder, the holder may exercise his or her options, if applicable, at any time within the earlier of (i) three months (or such other period as specified in an option agreement between the holder and us) after such termination or (ii) the expiration of the term of the option as set forth in an option agreement between the holder and us. In the event that a holder's continuous service with us or an affiliate of ours terminates due to the holder's permanent and total disability, the holder may exercise his or her options, if applicable, at any time within the earlier of (i) twelve months (or such other period as specified in an option agreement between the holder and us) after such termination or (ii) the expiration of the term of the option as set forth in an option agreement. In the event that a holder's continuous service with us or an affiliate of ours terminates due to the holder's death, the option will become fully vested and exercisable as of the date of termination, and may be exercised at any time within the earlier of (i) eighteen months (or such other period as specified in an option agreement between the holder and us) after death or (ii) the expiration of the term of the option as set forth in an option agreement. In the event that a holder dies within a certain time period following termination of service, the option may be exercised, if applicable, at any time within the earlier of (i) eighteen months (or such other period as specified in an option agreement between the holder and us) after death or (ii) the expiration of the term of the option as set forth in an option agreement. A holder may designate a beneficiary who may exercise the option following the holder's death. Individual option grants by their terms may provide for exercise within a longer period of time following termination of service.

The option term generally is extended in the event that exercise of the option within these periods is prohibited. A holder's option agreement may provide that if the exercise of the option following the termination of the holder's service would result in liability under the Securities Act of 1933, as amended (the "1933 Act"), then the option shall terminate on the earlier of (i) the expiration of the term of the option as set forth in the option agreement or (ii) three months (or such other period as specified in an option agreement between the holder and us) after the termination of the holder's service during which the exercise of the option would not be in violation of such registration requirements.

RESTRICTIONS ON TRANSFER

Options may be transferable to the extent provided in the option agreement. If the option does not provide for transferability, then the option shall not be transferable except by will or by the laws of descent and distribution, and shall be exercisable during the lifetime of the holder only by the holder. The holder may designate a third party to exercise the option in the event of the death of the holder. Stock bonus and restricted stock awards may be transferable only upon such terms and conditions as set forth in the stock award agreement, so long as the stock awarded remains subject to the agreement.

ADJUSTMENT PROVISIONS

Transactions not involving receipt of consideration by us, such as a merger, consolidation, reorganization, recapitalization, reincorporation, stock dividend, dividend in property other than cash, stock split, liquidating dividend, combination of shares, exchange of shares, change in corporate structure or other transactions not involving the receipt of consideration by us, may change the class(es) and number of shares of common stock subject to the Non-Officer Plan and outstanding awards. In that event, the Non-Officer Plan will be appropriately adjusted as to the class(es) and the maximum number of shares of

common stock subject to the Non-Officer Plan, and outstanding awards will be adjusted as to the class(es), number of shares and price per share of common stock subject to such awards.

EFFECT OF CERTAIN CORPORATE TRANSACTIONS

In the event of (i) the sale, lease or other disposition of all or substantially all of our assets, (ii) a merger or consolidation in which we are not the surviving corporation or (iii) a reverse merger in which we are the surviving corporation but the shares of common stock outstanding immediately preceding the merger are converted by virtue of the merger into other property (collectively, "corporate transaction"), then any surviving or acquiring corporation shall assume awards outstanding under the Non-Officer Plan or shall substitute similar awards. If any surviving or acquiring corporation refuses to assume such awards or to substitute similar awards, then with respect to awards held by holders whose service with us or an affiliate of ours has not terminated, the vesting of such awards (and, if applicable, the time during which such awards may be exercised) will be accelerated in full and the awards will terminate if not exercised (if applicable) at or prior to such corporate transaction.

The Non-Officer Plan also provides that, in the event of an acquisition by any person, entity or group within the meaning of Section 13(d) or 14(d) of the Securities and Exchange Act of 1934, as amended (the "1934 Act"), of the beneficial ownership (within the meaning of Rule 13d-3 promulgated under the 1934 Act) of our securities representing at least fifty percent of the combined voting power entitled to vote in the election of directors and provided that such acquisition is not as a result of, and does not constitute, a corporate transaction, then with respect to stock awards held by holder whose service with us or an affiliate of ours has not terminated, the vesting of such awards (and, if applicable, the time during which such stock awards may be exercised) shall be accelerated in full.

The acceleration of an award in the event of an acquisition, corporate transaction or a change in control event may be viewed as an anti-takeover provision, which may have the effect of discouraging a proposal to acquire or otherwise obtain our control.

DURATION, AMENDMENT AND TERMINATION

The board may suspend or terminate the Non-Officer Plan without stockholder approval or ratification at any time or from time to time; provided, however, that no amendment may impair the rights of any outstanding stock award under the Non-Officer Plan without the holder's consent.

FEDERAL INCOME TAX INFORMATION

Nonstatutory Stock Options, Restricted Stock Purchase Awards and Stock Bonuses. Nonstatutory stock options, restricted stock purchase awards and stock bonuses granted under the Non-Officer Plan generally have the following federal income tax consequences.

There are no tax consequences to the holder or us by reason of the grant. Upon acquisition of the stock, the holder normally will recognize taxable ordinary income equal to the excess, if any, of the stock's fair market value on the acquisition date over the purchase price. However, to the extent the stock is subject to certain types of vesting restrictions, the taxable event will be delayed until the vesting restrictions lapse unless the participant elects to be taxed on receipt of the stock. With respect to employees, we are generally required to withhold from regular wages or supplemental wage payments an amount based on the ordinary income recognized. Subject to the requirement of reasonableness and the satisfaction of a tax reporting obligation, we will generally be entitled to a business expense deduction equal to the taxable ordinary income recognized by the holder.

Upon disposition of the stock, the holder will recognize a capital gain or loss equal to the difference between the selling price and the sum of the amount paid for such stock plus any amount recognized as ordinary income upon acquisition (or vesting) of the stock. Such gain or loss will be long-term or short-term depending on whether the stock was held for more than one year.

SECTION 16(A) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

Section 16(a) of the 1934 Act requires our directors and executive officers, and persons who own more than ten percent of a registered class of our equity securities, to file with the SEC initial reports of ownership and reports of changes in ownership of our common stock and other equity securities. Officers, directors and greater than ten percent stockholders are required by SEC regulation to furnish us with copies of all Section 16(a) forms they file.

To our knowledge, based solely on a review of the copies of such reports furnished to us and written representations that no other reports were required, during the fiscal year ended December 31, 2003, all Section 16(a) filing requirements applicable to its officers, directors and greater than ten percent beneficial owners were complied with.

EXECUTIVE AND DIRECTOR COMPENSATION

COMPENSATION OF DIRECTORS

Under our compensation arrangement, each of our non-employee directors receives an annual retainer of $15,000, plus $1,000 per board meeting and $500 per committee meeting, including telephonic meetings. The chairman of the audit committee receives an additional $5,000 per year, payable quarterly. If a non-employee director is the chairman of any other committee, such director receives an additional $2,500 per year, payable quarterly. In the fiscal year ended December 31, 2003, we paid $107,875 total cash compensation to our non-employee directors for service as directors. The members of the board are also eligible for reimbursement for their expenses incurred in connection with attendance at board meetings in accordance with our policy.

Upon their election and reelection, to the extent shares are available under our 1994 Non-Employee Directors' Stock Option Plan (the "Non-Employee Directors' Plan"), each member of our board who is not an employee is automatically granted under the Non-Employee Directors' Plan without the board's or the stockholders' further action, an option to purchase 30,000 shares of our common stock for each three-year term to which he or she is elected. The non-employee directors who began with a one or a two-year term when we first instituted the staggered board or who are appointed to the board mid-term were granted 10,000 and 20,000 shares of common stock, respectively. The options vest monthly over the period of the term being served (in the event a non-employee director resigns during the year, our practice has been to vest the options monthly based on such director's actual service). Only non-employee directors are eligible to receive options under the Non-Employee Directors' Plan. Options granted under the Non-Employee Directors' Plan are intended not to qualify as incentive stock options under the Code. The exercise price of options granted under the Non-Employee Directors' Plan is 100% of the fair market value of the common stock subject to the option on the date of the option grant. Option grants under the Non-Employee Directors' Plan are non-discretionary. The term of options granted under the Non-Employee Directors' Plan is ten years. In the event of a merger with or into another corporation or a consolidation in which we are the surviving corporation, with the outstanding shares of our common stock immediately preceding the merger being converted by virtue of the merger into other property, or any other capital reorganization in which 50% of our shares entitled to vote are exchanged, the vesting of each option will accelerate in full and the option will terminate if not exercised prior to the consummation of the transaction. The acceleration of an award in the event of an acquisition, corporate transaction or a change in control event may be viewed as an anti-takeover provision, which may have the effect of discouraging a proposal to acquire or otherwise obtain our control.

There are currently options to purchase 14,600 shares available under the Non-Employee Directors' Plan. To the extent shares have been unavailable under the Non-Employee Directors' Plan, our practice has been for the board of directors to make grants under our 2000 Equity Incentive Plan in the amounts to which the non-employee directors otherwise would have been entitled under the Non-Employee Directors' Plan. Each non-employee director who has served on our board will receive an option to purchase 12,500 shares of our common stock under the 2000 Equity Incentive Plan upon the date of the board's meeting in September of each year. Such options vest monthly over one year. Non-employee directors are also eligible for discretionary grants of options under our 2000 Equity Incentive Plan.

In connection with this arrangement, Messrs. Glavin and Whitfield were each granted options to purchase 30,000 shares of our common stock in June 2003 in connection with their elections for a three-year term. In September 2003, Messrs. Brown, Glavin, Kuebler, Lerner and Whitfield and Dr. Perelman were granted options to purchase 12,500 shares of our common stock. In December 2003, Ms. Wang was granted options to purchase 37,375 shares of our common stock.

Options to purchase an aggregate of 518,475 shares of common stock have been granted to current non-employee directors under the Non-Employee Directors' Plan and the 2000 Equity Incentive Plan as of January 31, 2004, of which options to purchase 33,600 shares have been exercised. Options to purchase an

aggregate of 4,328,792 shares of common stock have been granted to directors who are our employees as of January 31, 2004, of which options to purchase 1,606,601 shares have been exercised.

EMPLOYMENT, SEVERANCE AND CHANGE OF CONTROL AGREEMENTS

In January 1995, the board amended the provisions of existing option grant forms under our 2000 Equity Incentive Plan to provide that upon a change in control, the vesting of all outstanding options held by executive officers would be accelerated by two years. This acceleration also applies to all subsequent grants made to executive officers. Options also accelerate and vest in full upon a change in control, asset sale, merger, consolidation or reverse merger, as described in our 2000 Equity Incentive Plan, in the event the acquiring company does not assume the options or does not substitute similar options. The options will also accelerate and vest in full upon certain securities acquisitions, as described in our 2000 Equity Incentive Plan.

In December 2002, the board adopted the Nektar Therapeutics Severance Benefit Plan (the "Benefit Plan"), pursuant to which a Named Executive Officer may participate and receive benefits. Under the Benefit Plan, the board has discretion on the amount of severance benefit a Named Executive Officer may receive.

On June 29, 2001, Nektar AL entered into an agreement with Dr. J. Milton Harris, pursuant to which Dr. Harris will receive additional compensation if he is terminated under certain circumstances. If Dr. Harris is terminated without cause (as cause is defined in the agreement) before June 29, 2005, he is entitled to (1) continuation of his base salary in effect at the time of termination for a 12 month period following the termination date and (2) accelerated vesting of an option to purchase 100,000 shares of our Common Stock (the "Option") such that, in addition to the number of shares vested as of the termination date, the number of shares that would have vested over the 12 month period following the termination date shall be vested as of the termination date. If Dr. Harris is terminated without cause (as cause is defined in the agreement) after June 29, 2005 and before June 29, 2006, he is entitled to (1) continuation of his base salary in effect at the time of termination until June 29, 2006 and (2) accelerated vesting of the Option such that, in addition to the number of shares vested as of the termination date, the number of shares that would have vested following the termination date until June 29, 2006 shall be vested as of the termination date.

On January 28, 2003, we entered into an offer letter with Mr. Bansal, our Chief Financial Officer, setting forth his initial base salary of $276,000 per year, a targeted variable compensation of $92,000 per year, and an initial bonus payment of $100,000. Mr. Bansal agreed to reimburse us for the full amount of the initial bonus if his employment terminates other than "without cause" by us or if he resigns before his first anniversary. Mr. Bansal was granted stock options to purchase 90,000 shares of our common stock at an exercise price set at the closing price of our stock on the day preceding Mr. Bansal's date of hire. In addition, we agreed to reimburse Mr. Bansal for certain relocation expenses, subject to forfeiture if his employment terminates other than "without cause" by us or if he resigns within one year after the relocation expenses have been reimbursed. We also agreed to provide Mr. Bansal with yearly mortgage or rental differential payments of $35,000, $27,000, and $20,000 for the first three years of service to us. On April 3, 2003, we entered into an addendum to the offer letter with Mr. Bansal providing for a $10,000 relocation allowance, subject to forfeiture.

REPORT OF THE AUDIT COMMITTEE OF THE BOARD OF DIRECTORS

The audit committee is currently comprised of four non-employee directors, Mr. Kuebler, Dr. Perelman, Ms. Wang and Mr. Whitfield. Under currently applicable rules, all members of the audit committee are considered independent. The board has amended the audit committee's written charter as of December 2003, which is attached as Appendix A to this proxy statement.

The audit committee acts on behalf of the board in fulfilling the board's oversight responsibility with respect to the financial statements and financial reporting process, the systems of internal accounting and financial controls, the annual independent audit of the financial statements, and the qualifications, independence and performance of the independent auditors.

The audit committee's primary responsibility is to oversee the financial reporting process, including the direct oversight of the independent auditors. The management is responsible for preparing the financial statements, and the independent auditors are responsible for auditing the financial statements.

The audit committee held nine meetings during 2003, all of which were attended by the company's independent auditors. The meetings were designed to facilitate and encourage private communication between the audit committee and the independent auditors, Ernst & Young LLP.

During these meetings, the audit committee reviewed and discussed the audited financial statements with management and Ernst & Young LLP. The audit committee believes that management maintains an effective system of internal controls that results in fairly presented financial statements. Based on these discussions, the audit committee recommended to the board that the audited financial statements be included in the Annual Report on Form 10-K. In April 2004, Nektar announced the restatement of non-cash gain, net loss and net loss per share reported for the fourth quarter and year ended December 31, 2003 included in the audited financial statements. The audit committee approved the restatement following extensive review and discussion with management and Ernst & Young, LLP.

The audit committee determined that the provision of the non-audit services by Ernst & Young LLP during 2003 was compatible with maintaining the principal auditors' independence.

The discussions with Ernst & Young LLP also included the matters required by Statement on Auditing Standards No. 61. The audit committee received written disclosures and the letter from Ernst & Young LLP regarding its independence as required by Independence Standards Board Standard No. 1. This information was discussed with Ernst & Young LLP.

REPORT OF THE ORGANIZATION AND COMPENSATION COMMITTEE OF THE BOARD OF DIRECTORS ON EXECUTIVE COMPENSATION

The board has delegated to the organization and compensation committee the authority to establish and administer compensation programs. The organization and compensation committee is comprised of two independent non-employee directors: Messrs. Michael A. Brown and Irwin Lerner. The organization and compensation committee is responsible for: (i) determining the most effective total executive compensation strategy, based upon our business objectives, needs and consistent with stockholders' interests; (ii) administering executive compensation plans, programs and policies; (iii) monitoring corporate performance and its relationship to compensation of executive officers; (iv) making appropriate recommendations to the board regarding the compensation levels for the Chairman and Chief Executive Officer; and (v) approving compensation levels for other executive officers and vice presidents.

COMPENSATION PHILOSOPHY

The primary goals of the compensation program are to help drive the attainment of key business objectives while enabling us to attract, retain and reward capable executives who can contribute to our continued success. Equity participation and a strong alignment to stockholders' interests are key elements of our compensation philosophy. Four key goals form the basis for compensation decisions for all employees:

1.: To attract and retain the most highly qualified management and employee team;
2.: To emphasize sustained performance by aligning rewards with stockholder interests, especially through the use of equity participation programs;
3.: To pay competitively compared to similar drug delivery and biopharmaceutical companies and to provide appropriate reward opportunities for achieving high levels of performance with regards to business objectives and to similar organizations in the marketplace; and
4.: To motivate executives and employees to achieve our annual and long-term business goals.

To meet these goals, the organization and compensation committee has adopted a mix of compensation elements, including salary, stock options and incentives (variable compensation program.).

BASE SALARY

The organization and compensation committee recognizes the importance of maintaining compensation practices and levels of compensation competitive with drug delivery and biopharmaceutical companies in comparable stages of development. Base salary represents the fixed component of the executive compensation program. The philosophy regarding base salaries is conservative, maintaining salaries approximately at the competitive industry median. Base salary levels are established based on an annual review of marketplace competitiveness and on the basis of individual performance. In this context base salaries for executives were increased for fiscal 2003 to a level consistent with the industry median. In 2003, we continued the variable compensation program implemented in 1996 for all employees, including all executive officers, which provides that a portion of total cash compensation is variable based on certain qualitative and quantitative criteria for both the company and the employee.

BONUSES (VARIABLE COMPENSATION)

Bonus awards are another component of the compensation program. Bonuses, if any, are linked to the achievement of specified corporate goals. Corporate performance goals on which 2003 bonuses were based on four broad categories:

1.: building product pipeline;

2.: building a long term business;
3.: organizational capabilities and infrastructure; and
4.: financial performance.

In July 2003, the organization and compensation committee reviewed the corporate performance goals for the first half of 2003 and determined that these goals had been substantially achieved. Based on such achievement, the organization and compensation committee awarded bonuses for all executive officers and other employees. In January 2004, the organization and compensation committee reviewed the corporate performance goals for the second half of 2003 and determined that these goals had been substantially achieved, and awarded bonuses for all executive officers and other employees.

STOCK OPTIONS

The option plans offered by the Company have been established to provide all the executive officers with an opportunity to share, along with stockholders, in our long-term performance. The organization and compensation committee strongly believes that a goal of the compensation program should be to provide key employees who have significant responsibility for driving our success with an opportunity to increase their ownership and potentially gain financially from stock price increases. The interests of stockholders, executives and employees are thereby closely aligned. Executives and other employees receive stock options at time of hire and are further eligible to receive stock options annually based on performance. All grants must be exercised according to the provisions of the relevant stock option plans. All outstanding options currently expire ten years from the date of grant.

As the base salaries for the executive officers are in the mid-range for comparable companies, the organization and compensation committee has used stock options as a primary incentive to attract and retain executive officers. Option amounts are based on an employee's level within our salary structure and the individual's performance. After considering the criteria relating to awarding stock options, the organization and compensation committee determined that all executive officers, including the Chief Executive Officer, would receive option grants in fiscal 2003. The options granted to executive officers in fiscal 2003 vest monthly over five years commencing upon the date of grant.

Section 162(m) of the Code limits deduction for federal income tax purposes of no more than $1 million of compensation paid to certain Named Executive Officers in a taxable year. Compensation above $1 million may be deducted if it is "performance-based compensation" within the meaning of the Code. The organization and compensation committee believes that at the present time it is unlikely that the compensation paid to any Named Executive Officer in a taxable year, which is subject to the deduction limit, will exceed $1 million. However, the organization and compensation committee has determined that stock awards granted under the Equity Incentive Plan with an exercise price at least equal to the fair market value of the common stock on the date of grant shall be treated as performance-based compensation.

CHIEF EXECUTIVE OFFICER COMPENSATION

The organization and compensation committee determines compensation for the Chief Executive Officer by analyzing the same factors and criteria upon which other executive officers' compensation is based. In the June 2003 meeting, the organization and compensation committee awarded Mr. Gill a bonus of approximately 50% of his base salary based on the determination that the corporate performance goals established in 2002 had been substantially achieved. Also at the June 2003 meeting, the organization and compensation committee agreed to recommend to the board that Mr. Gill receive an increase in salary and stock option grants for these same reasons. Under our executive compensation program, the total compensation mix for senior executives, including our Chief Executive Officer, emphasizes longer-term

rewards in the form of stock options. In June 2003, Mr. Gill received option grants to purchase 150,000 shares of Nektar common stock at the fair market value of the common stock on the date of grant.

SUMMARY

The organization and compensation committee believes that the compensation of the executives is appropriate and competitive with the compensation programs provided by other drug delivery and biopharmaceutical companies with whom we compete for talented people. The organization and compensation committee believes the compensation strategy, principles and practices result in a compensation program tied to stockholder returns and linked to the achievement of our annual and longer-term financial and operational results on behalf of the stockholders.

ORGANIZATION AND COMPENSATION COMMITTEE INTERLOCKS
AND INSIDER PARTICIPATION

The organization and compensation committee consists of two non-employee members: Michael A. Brown and Irwin Lerner. James B. Glavin was a member of the organization and compensation committee until December 10, 2003. Mr. Brown, Mr. Lerner and Mr. Glavin are not and have never been officers or employees of us. None of our executive officers serve as a member of a compensation committee of any entity that has one or more executive officers serving as a member of our organization and compensation committee.

We have not declared cash dividends on our common stock. Stockholder returns over the indicated period should not be considered indicative of future returns.

CERTAIN TRANSACTIONS

Our bylaws provide that we will indemnify our directors and may indemnify our 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 Amended and Restated Certificate of Incorporation, as amended, provides that the liability of 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 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 us or our stockholders; (ii) acts or omissions; (iii) violation of 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 or federal environmental laws.

In 2003, we paid $300,000 as rent for a facility in Alabama to Shearwater Polymers, LLC, of which Dr. Harris is a member. Dr. Harris is our Chief Scientific Officer, Nektar AL, and until March 4, 2004 he was our President, Nektar Therapeutics, AL, Corporation. We believe the rent reflects the fair market rate for comparable facilities in the geographic area. Further, in 2003, we paid $500,000 for legal services rendered by Alston & Bird LLP of which Paul F. Pedigo, Esq. is a partner. Mr. Pedigo is a relative by marriage to Dr. Harris. These transactions were approved by our audit committee. We believe this amount represents the fair market value of the services rendered.

On January 28, 2003, we entered into an offer letter with Ajay Bansal, our Chief Financial Officer. Please see "Employment, Severance and Change of Control Agreements" for a further description of this arrangement.

In June 2003 and July 2003, Alexandra Global Master Fund Ltd. and entities affiliated with Citigroup Inc., each a beneficial owner of more than five percent of our common stock, were issued approximately $3.0 million and $32.5 million, respectively, in aggregate principal amount of convertible subordinated notes which are convertible at the option of the holder, at any time on or prior to maturity, into shares of our common stock. The notes were sold only in the United States to certain qualified institutional buyers under an exemption from registration provided by Rule 144A of the 1933 Act. The notes are convertible at an initial conversion price of $11.35 per share, which is equal to a conversion rate of approximately 88.1057 shares per $1,000 principal amount of notes, subject to adjustment. Interest on the notes will accrue at a rate of 3.0% per year.

In October 2003, Alexandra Global Master Fund Ltd. and entities affiliated with Citigroup Inc., each a beneficial owner of more than five percent of our common stock, in privately negotiated transactions, exchanged and cancelled approximately $43.3 million and $32.5 million, respectively, in aggregate principal amount of our outstanding 3.5% convertible subordinated notes due October 2007, for the issuance of approximately $29.1 million and $21.9 million, respectively, in aggregate principal amount of newly issued 3% convertible subordinated notes due June 2010. The notes due June 2010 issued in the exchanges bear interest at a rate of 3% per annum and will mature in June 2010. The notes due June 2010 are convertible

into shares of our Common Stock at the rate of approximately 88.1057 shares per $1,000 principal amount of notes, which is equivalent to an initial conversion price of $11.35 per share.

In February 2004, Alexandra Global Master Fund Ltd., a beneficial owner of more than five percent of our common stock, in a privately negotiated transaction, converted approximately $29.1 million in aggregate principal amount of our outstanding 3% convertible subordinated notes due June 2010 (issued in October 2003) for shares of our common stock. The conversion price was $11.35 per share, for an aggregate of approximately 2.6 million shares of our common stock. In connection with the conversion, we agreed to pay $85.00 per $1,000 of the notes to be converted, for an aggregate payment of approximately $2.5 million.

HOUSEHOLDING OF PROXY MATERIALS

The SEC has adopted rules that permit companies and intermediaries (e.g., brokers) to satisfy the delivery requirements for proxy statements and annual reports with respect to two or more stockholders sharing the same address by delivering a single proxy statement addressed to those stockholders. This process, which is commonly referred to as "householding," potentially means extra convenience for stockholders and cost savings for companies.

This year, a number of brokers with account holders who are Nektar Therapeutics stockholders will be "householding" our proxy materials. A single proxy statement will be delivered to multiple stockholders sharing an address unless contrary instructions have been received from the affected stockholders. Once you have received notice from your broker that they will be "householding" communications to your address, "householding" will continue until you are notified otherwise or until you revoke your consent. If, at any time, you no longer wish to participate in "householding" and would prefer to receive a separate proxy statement and annual report, please notify your broker, direct your written request to Nektar Therapeutics, Secretary, 150 Industrial Road, San Carlos, California 94070 or contact our Secretary at (650) 631-3100. Stockholders who currently receive multiple copies of the proxy statement at their address and would like to request "householding" of their communications should contact their broker.

OTHER MATTERS

The board of directors knows of no other matters that will be presented for consideration at the annual meeting. If any other matters are properly brought before the meeting, it is the intention of the persons named in the accompanying proxy to vote on such matters in accordance with their best judgment.

A copy of our Annual Report to the Securities and Exchange Commission on Form 10-K for the fiscal year ended December 31, 2003, as amended, is available without charge upon written request to: Secretary, Nektar Therapeutics, 150 Industrial Road, San Carlos, California 94070.

APPENDIX A

NEKTAR THERAPEUTICS

AMENDED AND RESTATED AUDIT COMMITTEE CHARTER

This Charter governs the operations of the Audit Committee (the "Committee"). The Committee shall review and reassess the adequacy of the Charter annually or at such other times as the Committee deems appropriate and recommend any proposed changes to the Board of Directors (the "Board") for approval.

COMPOSITION OF THE COMMITTEE

The Board shall appoint members to the Committee. The Committee shall be comprised of at least three (3) directors who shall satisfy the independence and financial literacy requirements established by applicable law, rules and regulations of the Securities and Exchange Commission ("SEC") and the rules of the Nasdaq Stock Market ("Nasdaq"). All Committee members shall have a working familiarity with basic finance or accounting practices and be able to read and understand financial statements. To the extent required by applicable laws, rules and regulations, at least one member of the Committee shall satisfy the applicable Nasdaq financial experience requirements as in effect from time to time.

STATEMENT OF POLICY

The Committee shall act on behalf of the Board in fulfilling the Board's oversight responsibility to the stockholders, potential stockholders and the investment community relating to the Company's financial statements and the financial reporting process, the systems of internal accounting and financial controls, the annual independent audit of the Company's financial statements and the qualifications, independence and performance of the certified public accountants engaged as the Company's outside auditors.

In so doing, it is the responsibility of the Committee to maintain free and open communication between the Committee, the Company's independent auditors and the Company's management. In discharging its oversight role, the Committee is empowered to investigate any matter brought to its attention with full access to all books, records, facilities, and personnel of the Company.

The operation of the Committee shall be subject to the Bylaws of the Company as in effect from time to time and Section 141 of the Delaware General Corporation Law.

RESPONSIBILITIES AND PROCESSES

The primary responsibility of the Committee is to oversee the Company's financial reporting process (including direct oversight of the auditors) on behalf of the Board and report these activities to the Board. Management is responsible for preparing the Company's financial statements, and the independent auditors are responsible for auditing those financial statements.

The Committee's policies and procedures should remain flexible, in order to best react to changing conditions and circumstances. The Committee should take the appropriate actions to assure the stockholders and the Board that the Company maintains high quality financial reporting, sound business risk practices, and ethical behavior relating to accounting, internal accounting controls, auditing matters and financial disclosure and reporting.

To the extent the Committee believes appropriate based upon its periodic review thereof, the following shall be the principal recurring processes of the Committee in carrying out its oversight responsibilities. The processes are set forth as a guide with the understanding that the Committee may

A-1

supplement or, except as otherwise required by applicable laws, rules and regulations, deviate from them as appropriate. The Committee shall:

1. Evaluate the performance of the independent auditors, assess their qualifications, determine whether to retain or to terminate the existing auditors or to appoint and engage new independent auditors for the ensuing year. The Committee shall have the sole and exclusive authority with respect to such matters and the oversight of the independent auditors as a whole.

2. Review and determine the engagement of the independent auditors, including the overall scope and plans for their respective audits, the adequacy of staffing and compensation. Negotiate and execute, on behalf of the Company, any engagement letters with the Company's independent auditors with respect to such engagement, which actions may be pursuant to preapproval policies and procedures, including the delegation of preapproval authority to one or more Committee members so long as any such preapproval decisions are presented to the full Committee at the next scheduled meeting.

3. Establish guidelines and procedures with respect to the rotation of audit partners and other senior personnel engaged in providing audit services in accordance with applicable law and SEC and Nasdaq regulations (including regulations with respect to the independence of the independent auditors).

4. Review and approve the retention of the independent auditors for any permissible non-audit services in accordance with applicable law and SEC and Nasdaq regulations and the fees or other compensation for such services (such approval may be delegated to one or more Committee members, provided that all approvals of permissible non-audit services pursuant to this delegated authority be presented to the full Committee at its next meeting).

5. At least annually, discuss with the independent auditors and review the auditors' independence from management and the Company, including the provision of non-audit services, past employment by the independent auditors of current or prospective Company personnel, the matters included in the written disclosures required by the Independence Standards Board and other relationships or services that could affect the objectivity of the independent auditors and assess and otherwise take appropriate action to oversee the independence of the independent auditors.

6. Review with the independent auditors any management or internal control letter issued or, to the extent practicable, proposed to be issued by the independent auditors and management's response, if any, to such letter, as well as additional material written communications between the independent auditors and management.

7. Review with management and the independent auditors the scope, adequacy and effectiveness of the Company's financial reporting controls, including analysis reports prepared by management and the independent auditors of significant financial reporting issues and judgments made in connection with the preparation of the Company's financial statements, including any special audit steps taken in the event of material control deficiencies, and an analysis of the effect of alternative GAAP methods on the Company's financial statements.

8. Establish and maintain procedures for the receipt, retention and treatment of complaints received by the Company (whether initiated by employees of the Company or third parties) with respect to accounting, internal accounting controls or auditing matters, which shall include procedures for the confidential and anonymous submission by employees of concerns regarding questionable accounting or auditing matters.

9. Undertake the responsibility to investigate and resolve any disagreements between the Company's management and the independent auditors regarding the Company's financial reporting, accounting practices or accounting policies.

10. Meet as deemed necessary, but not less than twice annually, with senior management and the independent auditors in separate executive sessions. In connection with separate executive sessions held

A-2

with the independent auditors, discuss matters relevant to the quality and integrity of the Company's financial reporting, the results of the independent auditors' examinations and inquire as to the independent auditors' evaluation of the Company's financial and accounting policies and controls.

11. Discuss with management and the independent auditors the results of the independent auditors' review of the Company's quarterly financial statements, prior to public disclosure or prior to the filing of the Company's Quarterly Report on Form 10-Q with the SEC. Such review shall include all matters required by applicable laws, rules and regulations to be discussed with the independent auditors prior to the filing of such report as well as such matters required to be communicated to the Committee by the independent auditors under Statement on Auditing Standards No. 61.

12. Discuss with management and the independent auditors the financial statements to be included in the Company's Annual Report on Form 10-K (or the annual report to stockholders if distributed prior to the filing of Form 10-K). Discuss with management and the independent auditors the results of the annual audit, including the auditors' judgment about the quality, not just acceptability, of accounting principles, any changes in accounting procedures, the reasonableness of significant judgments and estimates (including material changes in estimates), the clarity of the disclosures in the financial statements and any audit adjustments noted or proposed by the auditors (whether "passed" or implemented in the financial statements).
