Explanation of Responses:

*	If the form is filed by more than one reporting person, see Instruction 4(b)(v).
**	Intentional misstatements or omissions of facts constitute Federal Criminal Violations. See 18 U.S.C. 1001 and 15 U.S.C. 78ff(a).
(1)	This option was granted on February 6, 2013 and vests in monthly installments over the four-year period following the grant date.
(2)	This stock option is subject to both time-based vesting and performance-based vesting conditions, both of which must be met before the shares subject to the option become vested and exerciseable. The time-based vesting is on a monthly pro-rata basis over a period of four (4) years from the grant date (February 6, 2013). The performance-based vesting condition will be met only if Nektar (or a licensee) files a new drug registration with the FDA or the European Medicines Agency for a significant drug candidate program including, without limitation, the following: (1) naloxegol (an oral peripherally-acting opioid antagonist); (2) etirinotecan pegol (a topoisomerase I inhibitor); (3) NKTR-061/Amikacin Inhale (a drug-device combination for an inhaled solution of amikacin); or (4) BAX-855 (a longer-acting (PEGylated) form of a full-length recombinant factor VIII (rFVIII) protein).

Note: File three copies of this Form, one of which must be manually signed. If space is insufficient, see Instruction 6 for procedure.
