Form of Non-employee Director Stock Option Agreement



 EXHIBIT 10.3 
 NEKTAR THERAPEUTICS 
 2000 EQUITY
INCENTIVE PLAN 
 STOCK OPTION AGREEMENT 
 Pursuant to the Stock Option Grant Notice (“Option Notice”) and this Stock Option Agreement, Nektar Therapeutics (the
“Company”) has granted you an option under its 2000 Equity Incentive Plan (the “Plan”) to purchase the number of shares of the Company’s Common Stock indicated in the Option Notice at the exercise
price indicated in the Option Notice. Defined terms not explicitly defined in this Stock Option Agreement but defined in the Plan shall have the same definitions as in the Plan. 
 The details of your option are as follows: 
 1. VESTING. Subject to the limitations contained herein, your option will vest as provided in the Option Notice, provided that vesting will cease upon the termination of your Continuous
Service. Notwithstanding the foregoing, (i) in the event your Continuous Service is terminated as a result of your death, your option shall become fully vested and exercisable as of the date of your death, or (ii) upon the closing of a
Corporate Transaction, your option shall become fully vested and exercisable. 
 2. NUMBER OF
SHARES AND EXERCISE PRICE. The number of shares subject to your option and your exercise price per share referenced in the Option Notice may be adjusted
from time to time for capitalization adjustments, as provided in the Plan. 
 3. EXERCISE RESTRICTION
FOR NON-EXEMPT EMPLOYEES. If you are an Employee eligible for overtime compensation under the Fair Labor Standards Act of 1938, as amended (i.e., a “Non-Exempt
Employee”), you may not exercise your option until at least six (6) months following the Date of Grant specified in your Option Notice, notwithstanding any other provision of your option. 
 4. METHOD OF PAYMENT. Payment of the exercise price is due in full upon
exercise of all or any part of your option. You may elect to make payment of the exercise price in one or more of the following forms: 
 (a) In cash or by check; 
 (b) In the Company’s sole discretion at the time your option is exercised and
provided that at the time of exercise the Common Stock is publicly traded and quoted regularly in The Wall Street Journal, pursuant to a program developed under Regulation T as promulgated by the Federal Reserve Board which, prior to the
issuance of Common Stock, results in either the receipt of cash (or check) by the Company or the receipt of irrevocable instructions to pay the aggregate exercise price to the Company from the sales proceeds; or 


					
		  	1.	  	









 (c) In the Company’s sole discretion at the time your option is granted (or subsequently, if
your option is a nonstatutory stock option) and provided that at the time of exercise the Common Stock is publicly traded and quoted regularly in The Wall Street Journal, by delivery of already-owned shares of Common Stock either that you
have held for the period required to avoid a charge to the Company’s reported earnings (generally six months) or that you did not acquire, directly or indirectly from the Company, that are owned free and clear of any liens, claims, encumbrances
or security interests, and that are valued at Fair Market Value on the date of exercise. “Delivery” for these purposes, in the sole discretion of the Company at the time your option is exercised, shall include delivery to the Company of
your attestation of ownership of such shares of Common Stock in a form approved by the Company. Notwithstanding the foregoing, your option may not be exercised by tender to the Company of Common Stock to the extent such tender would constitute a
violation of the provisions of any law, regulation or agreement restricting the redemption of the Company’s stock. 
 5.
SECURITIES LAW COMPLIANCE. Notwithstanding anything to the contrary contained herein, your option may not be exercised unless the shares issuable upon exercise of your
option are then registered under the Securities Act or, if such shares are not then so registered, the Company has determined that such exercise and issuance would be exempt from the registration requirements of the Securities Act. The exercise of
your option must also comply with other applicable laws and regulations governing the option, and the option may not be exercised if the Company determines that the exercise would not be in material compliance with such laws and regulations.

 6. TERM. The term of your option commences on the Date of Grant and expires upon the
earliest of the following: 
 (a) three (3) months after the termination of your Continuous Service for any reason
other than death or Disability, provided that (i) if during any part of such three (3)-month period the option is not exercisable solely because of the condition set forth in Section 5, the option shall not expire until the earlier of the
Expiration Date indicated on the Option Notice or until it shall have been exercisable for an aggregate period of three (3) months after the termination of your Continuous Service, and (ii) if (x) you are a Non-Exempt Employee,
(y) you terminate your Continuous Service within six (6) months after the Date of Grant specified in your Option Notice, and (z) you have vested in a portion of your option at the time of your termination of Continuous Service, your
option shall not expire until the earlier of (A) the later of the date that is seven (7) months after the Date of Grant specified in your Option Notice or the date that is three (3) months after the termination of your Continuous
Service or (B) the Expiration Date; 
 (b) twelve (12) months after the termination of your Continuous Service due to
Disability; 
 (c) eighteen (18) months after your death if you die either during your Continuous Service or within three
(3) months after your Continuous Service terminates for a reason other than death; 


					
		  	2.	  	









 (d) the Expiration Date indicated in the Option Notice; or 
 (e) the eighth (8th) anniversary of the Date of Grant. 
 Note, if your option is an incentive stock option, to obtain the federal income tax advantages associated with an “incentive stock option,” the Code requires that at all times beginning on the Date of Grant
of your option and ending on the day three (3) months before the date of your option’s exercise, you must be an employee of the Company or an Affiliate, except in the event of your death or Disability. The Company has provided for extended
exercisability of your option under certain circumstances for your benefit but cannot guarantee that your option will necessarily be treated as an “incentive stock option” if you continue to provide services to the Company or an Affiliate
as a Consultant or Director after your employment terminates or if you otherwise exercise your option more than three (3) months after the date your employment terminates. 
 7. EXERCISE. 
 (a)
You may exercise the vested portion of your option during its term by delivering a Notice of Exercise (in a form designated by the Company) together with the exercise price to the Secretary of the Company, or to such other person as the Company
may designate, during regular business hours, together with such additional documents as the Company may then require. 
 (b) By
exercising your option you agree that, as a condition to any exercise of your option, the Company may require you to enter an arrangement providing for the payment by you to the Company of any tax withholding obligation of the Company arising by
reason of (1) the exercise of your option, (2) the lapse of any substantial risk of forfeiture to which the shares of Common Stock are subject at the time of exercise, or (3) the disposition of shares of Common Stock acquired upon
such exercise. 
 (c) If your option is an incentive stock option, by exercising your option you agree that you will notify the
Company in writing within fifteen (15) days after the date of any disposition of any of the shares of the Common Stock issued upon exercise of your option that occurs within two (2) years after the date of your option grant or within one
(1) year after such shares of Common Stock are transferred upon exercise of your option. 
 8.
TRANSFERABILITY. Your option is not transferable, except by will or by the laws of descent and distribution, and is exercisable during your life only by you. Notwithstanding the foregoing, by
delivering written notice to the Company, in a form satisfactory to the Company, you may designate a third party who, in the event of your death, shall thereafter be entitled to exercise your option. 
 9. OPTION NOT A SERVICE CONTRACT. Your
option is not an employment or service contract, and nothing in your option shall be deemed to create in any way whatsoever any obligation on your part to continue in the employ of the Company or an Affiliate, or of the Company or an Affiliate to
continue your employment. In addition, nothing in your option shall 



					
		  	3.	  	









 
obligate the Company or an Affiliate, their respective shareholders, Boards of Directors, Officers or Employees to continue any relationship that you might
have as a Director or Consultant for the Company or an Affiliate. 
 10. WITHHOLDING OBLIGATIONS.

 (a) At the time your option is exercised, in whole or in part, or at any time thereafter as requested by the Company, you hereby
authorize withholding from payroll and any other amounts payable to you, and otherwise agree to make adequate provision for (including by means of a “cashless exercise” pursuant to a program developed under Regulation T as promulgated by
the Federal Reserve Board to the extent permitted by the Company), any sums required to satisfy the federal, state, local and foreign tax withholding obligations of the Company or an Affiliate, if any, which arise in connection with your option.

 (b) Upon your request and subject to approval by the Company, in its sole discretion, and compliance with any applicable conditions
or restrictions of law, the Company may withhold from fully vested shares of Common Stock otherwise issuable to you upon the exercise of your option a number of whole shares having a Fair Market Value, determined by the Company as of the date of
exercise, not in excess of the minimum amount of tax required to be withheld by law (or such lower amount as may be necessary to avoid variable award accounting). Shares of Common Stock shall be withheld solely from fully vested shares of Common
Stock determined as of the date of exercise of your option that are otherwise issuable to you upon such exercise. Any adverse consequences to you arising in connection with such share withholding procedure shall be your sole responsibility.

 (c) Your option is not exercisable unless the tax withholding obligations of the Company and/or any Affiliate are satisfied.
Accordingly, you may not be able to exercise your option when desired even though your option is vested, and the Company shall have no obligation to issue a certificate for such shares of Common Stock or release such shares of Common Stock from any
escrow provided for herein unless such obligations are satisfied. 
 11. NOTICES. Any
notices provided for in your option or the Plan shall be given in writing and shall be deemed effectively given upon receipt or, in the case of notices delivered by the Company to you, five (5) days after deposit in the United States mail,
postage prepaid, addressed to you at the last address you provided to the Company. 
 12. GOVERNING PLAN
DOCUMENT. Your option is subject to all the provisions of the Plan, the provisions of which are hereby made a part of your option, and is further subject to all interpretations, amendments, rules and
regulations which may from time to time be promulgated and adopted pursuant to the Plan. In the event of any conflict between the provisions of your option and those of the Plan, the provisions of the Plan shall control.
