 EMPLOYMENT TRANSITION AND GENERAL RELEASE AGREEMENT 

This Employment Transition and General Release Agreement (“Agreement”) is entered between Rinko Ghosh
(“you” or “Employee”) and Nektar Therapeutics, a Delaware corporation (the “Company”). 
 1. Resignation Date and Transition Period.  
 (a) Resignation
Date. You agree to resign as an at-will employee of the Company on March 15, 2014 (the “Resignation Date”), unless you and the Company mutually agree to a different Resignation Date. 

(b) Title and Duties. From the Effective Date of this Agreement (as defined in Section 8(h) below) through the Resignation
Date (referred to herein as the “Transition Period”), your duties and responsibilities will include, but are not limited to, providing transition assistance and performing other duties as assigned by the Senior Vice President
of Human Resources of the Company. The current expectation is that you will be working on specified collaboration partnering activities during the Transition Period, the scope of which will be defined by the Senior Vice President of Human Resources.
During the Transition Period, (i) you will not supervise employees or have any employees report to you and you will work remotely and will only be required to be on-site at Nektar facilities as is agreed in advance between you and the Senior
Vice President of Human Resources; and (ii) you will have no authority to represent the Company to third parties or to bind the Company to any contractual obligations, whether written, oral or implied, or represent that you have such authority,
unless authorized to do so in writing by an officer of the Company. During the Transition Period, you shall continue to abide by all of the Company’s policies and procedures in effect from time to time and perform your job duties in good faith
to the best of your abilities. 
 (c) Compensation and Benefits. During the Transition Period, you will be paid at your
current base salary subject to applicable withholdings and deductions, payable on the Company’s customary payroll dates. Effective February 1, 2014, your base salary will increase by three percent (3%) from $455,100 to $468,753 per
annum. If eligible, you may continue to participate in the Company’s benefit plans, subject to the terms and conditions of those plans including without limitation the Company’s Change of Control Severance Benefit Plan. Stock options,
restricted stock units, and equity incentives, if any, will continue to vest, pursuant to the terms of any applicable equity incentive plans (the “Plans”) and any agreements issued to you pursuant to such plans (the
“Option Agreements”). During the Transition Period, you will not earn any bonus or performance-based incentive compensation, notwithstanding any provision to the contrary in any incentive compensation or bonus plan.

 2. Employee Acknowledgements. You acknowledge: (a) receipt of all compensation and benefits due through the date
of this Agreement, as a result of services performed for the Company; (b) you have reported to the Company any and all work-related injuries incurred during employment; (c) the Company properly provided any leave of absence because of your
or a family member’s health condition, and you have not been subjected to any improper treatment, conduct or actions due to a request for or taking such leave. 








 3. Consideration. In consideration of your promises in this Agreement and your
agreement to sign a supplemental resignation date release in the form attached to this Agreement after your actual Resignation Date, the Company will pay to you the gross amount of $204,795, subject to applicable deductions and withholdings, less
any amount due for a negative paid time off balance payable after this Agreement becomes effective as described below in Section 8(h). 
 4. Release.  
 (a) General Release. In exchange for the
consideration described above, you, personally and for your heirs, executors, administrators, successors and assigns, hereby generally and completely release the Company and its subsidiaries, successors, predecessors and affiliates, and its and
their respective partners, members, directors, officers, employees, stockholders, shareholders, agents, attorneys, predecessors, insurers, affiliates and assigns (all of whom are referred to throughout this Agreement as “Released
Parties”), from any and all claims, demands, actions, causes of action, suits, damages, losses, expenses, liabilities, and obligations, both known and unknown, individually or as part of a group action, that arise out of or are in any
way related to events, acts, conduct, or omissions occurring at any time through the date you sign this Agreement. This general release includes, but is not limited to, to all matters in law, equity, contract, tort, or pursuant to statute, including
but not limited to (i) any and all claims under Title VII of the Civil Rights Act of 1964, the Americans with Disabilities Act, and the Age Discrimination in Employment Act (“ADEA”), (ii) any and all claims relating
to, or arising from, any right to receive or purchase equity of the Company, including, without limitation, any claims for fraud, misrepresentation, breach of fiduciary duty, breach of duty under applicable state corporate law, and securities fraud,
and (iii) any and all claims under any state or federal law or any other federal, state or local statute, rule, ordinance, or regulation. 

You are releasing all rights under section 1542 of the California Civil Code. Section 1542 provides as follows: 

A general release does not extend to claims which the creditor does not know or suspect to exist in his or her favor at the time of
executing the release, which if known by him or her must have materially affected his or her settlement with the debtor. 
 You intend these
consequences even as to claims for damages that may exist as of the date this Agreement is executed that you do not know exist and which if known, would materially affect your decision to execute this Agreement, regardless of whether the lack of
knowledge is the result of ignorance, oversight, error, negligence or any other cause. 
 You represent that you have no lawsuits, claims or
actions pending in your name, or on behalf of any other person or entity, against the Released Parties or any of them.

(i) for unemployment or workers’ compensation, (ii) for vested rights under ERISA-covered employee benefit plans as applicable on the date you sign this Agreement, (iii) that may arise after you sign this Agreement, and
(iv) which cannot be released by private agreement. Nothing in this Agreement prevents you from filing a charge or complaint with or from participating in an investigation or proceeding conducted by any federal, state or local agency charged
with the enforcement of any employment laws, including but not limited to the Equal Employment Opportunity Commission (“EEOC”) and the National Labor Relations Board (“NLRB”), although by signing this
release you are waiving rights to individual relief based on claims asserted in such a charge or complaint. 
 5.
Confidentiality. Except as disclosed in the Company’s filings with the Securities and Exchange Commission, the provisions of this Agreement shall be held in strictest confidence by you and shall not be publicized or disclosed in any manner
whatsoever by you at any time to any person other than your lawyer or accountant, a governmental agency, or your immediate family without the prior written consent of an officer of the Company, except as necessary in any legal proceedings directly
related to the provisions and terms of this Agreement, to prepare and file income tax forms, or as required by court order after reasonable notice to the Company. Nothing in this Agreement shall prevent you from providing information to the NLRB
upon request, nor shall this provision prevent Employee from exercising Employee’s rights under Section 7 of the National Labor Relations Act. You and the Company specifically disclaim any intent to enter into this Agreement in exchange
for a promise not to reveal to any government entity, including any court or agency, conduct that could be construed as a violation of federal law. 
 6. Proprietary Information. You acknowledge access to and receipt of confidential business and proprietary information regarding the Company and its clients while working. This information may be
in a variety of paper and electronic forms. You agree not to make any such information known to any member of the public and to comply with all applicable ethical responsibilities related to client confidences and secrets. You further agree to

property, files or documents obtained as a result of employment with the Company, except those items that the Company specifically agrees in writing to permit you to retain. 
 7. Non-Disparagement. You agree to refrain from any disparaging statements about Nektar or any of the other Released Parties including, without limitation, the Company’s directors, officers,
employees, customers, collaboration partners, business, products, research, services, or methods of doing business. Similarly, Nektar agrees that its executive officers and directors shall not make any disparaging statements to any third party about
you. Notwithstanding the foregoing, it shall not be a violation of this Section 7 for either party to enforce the terms of this Release, initiate or engage in any legal proceeding to enforce any provision of this Release, provide truthful
statements in response to a subpoena, Court order or arbitral order, or provide truthful information to a governmental agency in connection with any governmental, regulatory or administrative agency proceeding.
