August 9, 2007


Mr. Tim Harkness
[Personal Address]
[Personal Address]


Dear Tim:

I am pleased and excited to offer you the position of Senior Vice President and
Chief Financial Officer of Nektar Therapeutics ("Nektar" or the "Company")
reporting directly to me. Accordingly, I present you with this offer letter
agreement setting forth certain terms and conditions of your employment.
Capitalized terms used herein and not defined shall have the meanings ascribed
to them in the Company's Change of Control Severance Benefit Plan, as it may be
amended from time to time (the "COC Plan").

Your annual cash compensation will consist of two components: base salary and an
annual performance bonus. Your base salary will be $440,000 on an annual basis
and paid in accordance with Nektar's regular payroll schedule. Your annual
performance bonus target each year will be at least 50% of your annual base
salary for each annual period and $220,000 pro-rated for your partial period of
service in 2007 ("Target Annual Bonus"). Your base salary and Target Annual
Bonus shall be subject to annual performance review by the Compensation
Committee of the Board of Directors ("Compensation Committee") in consultation
with me for appropriate upward adjustment. The actual amount of your annual
performance bonus will range from 0% to 150% of the Target Annual Bonus based on
the Compensation Committee's assessment in consultation with me of the
achievement of a combination of annual corporate objectives and your achievement
of personal objectives agreed upon by you and me at the beginning of each annual
performance period; provided that your objectives for your partial period of
service in 2007 will be agreed upon by you and I as soon as practicable
following your start date. Your annual performance bonus for the prior year will
be paid in the first calendar quarter of each year within the period of time
required to avoid taxes and penalties under Section 409A of the Internal Revenue
Code.

Subject to approval by the Compensation Committee prior to and effective as of
your first day of full-time employment with Nektar ("Start Date"), you will be
granted (i) a stock option to purchase 200,000 shares of Nektar common stock
(the "Initial Option", which together with any subsequent stock options you may
receive, are the "Stock Options") under Nektar's 2000 Equity Incentive Plan
("2000 Plan") and (ii) a restricted stock unit for 10,000 shares ("RSU") of
Nektar common stock under the 2000 Plan. The maximum number of shares subject to
the Stock Options will be granted as incentive stock options within the meaning
of Section 422 of the Internal Revenue Code to the extent permissible under
Section 10(d) of the 2000 Plan. The remainder of shares subject to the Stock
Options will be granted as non-statutory stock options. The exercise price will
be set at the closing price of Nektar's common stock on Nasdaq on your Start
Date in the case of the Initial Option or at the date determined by the
Compensation Committee in the case of any subsequent Stock Options. The shares
subject to the Initial Option will vest according to a 4-year vesting schedule
for so long as you provide Continuous Service (as defined in the 2000 Plan) to
the Company with 25% of the shares subject to the Initial Option vesting on the
one year anniversary of your Start Date and the remainder vesting monthly on a
pro-rata basis over the following 3 years. The shares subject to the RSU will
vest according to a 4-year vesting schedule for so long as you provide
Continuous Service to the Company with 25% of the shares subject to the RSU
vesting on the one year anniversary of your Start Date and the remainder vesting
on an annual pro-rata basis over the following 3 years.

                                       5

You will be eligible for annual equity awards, in the sole discretion of the Compensation Committee, based on the Compensation Committee's review, in consultation with me, of your individual performance and annual equity compensation levels of chief financial officers of comparator companies as analyzed by a reputable, nationally-recognized, independent compensation consultancy firm. You will also be eligible to participate in Nektar's executive benefits program including medical, dental and vision insurance, term life insurance, 401(k), the flexible health spending plan, short & long-term disability upon the terms specified in those plans, and the COC Plan. Your employment is by continued mutual agreement and may be terminated at will with or without cause by either you or Nektar at any time with or without advanced notice. You will also be required to enter into Nektar's standard Employment Agreement, a copy of which is attached as Exhibit A hereto. As we have discussed, we currently expect your Start Date to be on August 24, 2007. In the event of your death or Disability (as defined in the 2000 Plan), (a) 50% of the unvested shares under your Stock Options will automatically vest in the event of your Disability and 100% shall automatically vest in the event of your death, (b) Nektar will pay to you or your estate, as applicable, all unreimbursed expenses, all of your then accrued but unpaid base salary, and your target bonus prorated for the portion of the last year in which you were employed by Nektar prior to death or Disability, and (c) you and your dependents shall be entitled to continued medical, dental, and vision insurance for yourself and your dependents, at your or their expense, at the same level of coverage as was provided to you and your dependents under Nektar's insurance and benefits plans immediately prior to the termination by electing COBRA continuation coverage in accordance with applicable law. In the event your employment is terminated for reasons not related to a Change of Control (a) by the Company without Cause; or (b) by you for a Good Reason Resignation, then you and the Company will meet in good faith to discuss the terms of an appropriate separation. In any event, at a minimum, the Company will enter into a severance arrangement with you which will include the following: (i) a fully effective mutual waiver and release in such form as the Company may reasonably require, (ii) a cash severance payment equal to your total annual cash compensation target (defined as your current monthly base salary annualized for 12 months, plus your bonus target multiplied by the expected pay-out percentage used by the Company for its GAAP financial statements in the previous calendar quarter, but not to exceed 100%), payable in accordance with the severance payment schedule described in the COC Plan and subject to such delay in payment required for compliance with Section 409A, (iii) pro-rata vesting credit (based on conversion of the vesting schedule to a monthly vesting schedule) on your Initial Option through the date of termination if your termination occurs prior to the first anniversary of the Start Date, based on months completed since your Start Date, (iv) the exercise period for the vested and unexercised portion of your Initial Option shall be 12 months following the termination date and (v) the Company shall pay all applicable COBRA payments for you and your family for one year after the termination date (such payments shall cease in the event that you become eligible for comparable benefits with another employer). 6

In compliance with the terms of the Federal Immigration Reform and Control Act, you will be required to provide us with proof of authorization to work and proof of identity. The terms, compensation and benefits set forth in this letter, which shall be governed by California law, without reference to principles of conflicts of laws, may not be reduced without your prior written consent and shall be binding upon and inure to the benefit of (a) your heirs, executors, and legal representatives upon your death and (b) any person or entity which at any time, whether by purchase, merger, or otherwise, directly or indirectly acquires all or a majority of the assets, business, capital stock, or voting stock of the Nektar. Any such person or entity shall be deemed substituted for the Nektar under this letter for all purposes. 7

Tim, I am delighted at the prospect of your leadership at Nektar as Senior Vice President and Chief Financial Officer. Please feel free to call me if you have any questions and I look forward to working with you. Sincerely, /s/ Howard W. Robin Howard W.

Employment at Will. I agree that this Agreement does not guarantee my continued employment with the Company. I acknowledge that, unless I enter into a written employment agreement with the Company that provides for a specified period of employment, I am employed "at-will," meaning that either the Company or I may terminate the employment relationship at any time, for any or no reason, with or without cause or prior notice. 3. Assignment of Developments: a. Assignment to Company. If at any time or times during my employment or other association with the Company, I shall (either alone or with others) make, conceive, create, discover, invent or reduce to practice any development that (i) relates to the business of the Company or any of the products or services being explored, developed, manufactured or sold by the Company or which may be used in relation therewith; or (ii) results from tasks assigned to me by the Company; or (iii) results from the use of premises or personal property (whether tangible or intangible) owned, leased or contracted for by the Company (hereinafter collectively referred to as "Developments"), then all such Developments and the benefits thereof are and shall immediately become the sole and absolute property of the Company and its assigns, as works made for hire or otherwise.

b. Requirement to Provide Assistance. I agree to assist the Company, or its designee, at the Company's expense, in every proper way to secure the Company 's rights in the Developments and any copyrights, patents, trademarks, and trade secret rights or other intellectual property rights in connection with any such Developments in any and all countries, including the disclosure to the Company of all pertinent information and data with respect thereto, the execution of all applications, specifications, oaths, assignments and all other instruments which the Company shall deem necessary in order to apply for and obtain such rights and in order to assign and convey to the Company, its successors, assigns, and nominees the sole and exclusive rights, title and interest in and to such Developments, and any copyrights, patents, trademark and other intellectual property rights relating thereto. I further agree that my obligation to execute or cause to be executed, when it is in my power to do so, any such instrument or papers shall continue after the termination of this Agreement. If the Company is unable, because of my mental or physical incapacity or for any other reason, to secure my signature to apply for or to pursue any application for any United States or foreign patents or copyright registrations covering Developments or original works of authorship assigned to the Company as above, then I hereby irrevocably designate and appoint the Company and its duly authorized officers and agents as my agent and attorney in fact, to act for and in my behalf and stead to execute and file any such applications and to do all other lawfully permitted acts to further the prosecution and issuance of letters patent or copyright registrations thereon with the same legal force and effect as if executed by me. c.
