 (b) if, as a
result of the termination of Executive’s employment, Executive and Executive’s spouse and dependent children are eligible for and timely (and properly) elect COBRA continuation coverage under the Company’s group health plan(s), the

continuation coverage under the Company’s group health plan(s), whichever period is the shortest, but only to the extent that the Company would have paid such premiums had Executive remained employed by the Company; 
 (c) severance payments equal, in the aggregate, to one (1) times Executive’s annual base salary as of the date of the Notice of
Termination, payable as provided in Section 7.8(b). 
 7.3 Termination Other than for Cause or for Good Reason During

 (a) “Good Reason” shall mean the occurrence of any of the following conditions, without the consent of Executive:

  

	 	(i)	a material reduction in Executive’s base compensation; 

  

	 	(ii)	a material reduction in Executive’s authority, duties or responsibilities; provided, however, that a change in the person or office to which Executive reports,
without a corresponding reduction in authority, duties or responsibilities, shall not constitute Good Reason; 

  

	 	(iii)	a material reduction in the budget over which Executive retains authority; 

  

	 	(iv)	requirement by a Successor Company that Executive relocate Executive’s principal place of employment to a location that is more than fifty (50) miles from the

	 	(v)	any other action or inaction that constitutes a material breach by the Company or a Successor Company of this Agreement. 

 (b) Notwithstanding any provision in this Agreement to the contrary, termination of employment by Executive will not be for Good Reason
unless (i) Executive notifies the Company or the Successor Company in writing of the existence of the condition which Executive believes constitutes Good Reason within ninety (90) days of the initial existence of such condition (which
notice specifically identifies such condition), (ii) the Company or the Successor Company fails to remedy such condition within thirty (30) days after the date on which it receives such notice (the “Remedial
Period”), and (iii) Executive actually terminates employment within thirty (30) days after the expiration of the Remedial Period and before the Company or the Successor Company remedies such condition. If Executive terminates
employment before the expiration of the Remedial Period or after the Company or the Successor Company remedies the condition (even if after the end of the Remedial Period), then Executive’s termination will not be considered to be for Good
Reason. Executive may combine the notice required by this Section 7.5(b) with the Notice of Termination.

 7.7 Change in Control 
 As used herein, a “Change in

Business Combination (including, without limitation, a corporation which as a result of such transaction owns the Company or all or substantially all of the Company’s assets either directly or through one or more subsidiaries), (B) no
Person (excluding (1) any one or more Series B Purchasers, (2) any corporation resulting from such Business Combination, or (3) any employee benefit plan (or related trust) of the Company or such corporation resulting from such

	 	(i)	 If Code Section 409A does not apply to the payments that would be made during the first sixty (60) days following the Termination Date, then
payments shall begin as of the first semi-monthly pay day following the date on which



  

 -10- 









	 	 
Executive’s release under Section 9(a) becomes effective. The initial payment shall include any such installments that would have been paid prior to such pay day had payments commenced
on the first semi-monthly pay day following the Termination Date; and 


  

	 	(ii)	If Code Section 409A applies to the payments that would be made during the first sixty (60) days following the Termination Date, then payments shall begin as

 (c) Subject to Section 21,
any payments payable to Executive pursuant to Sections 7.3(b) and (e) shall be made to Executive in a lump sum on the first business day following the date on which Executive’s release under Section 9(a) becomes effective, unless
any portion of such payments is subject to Code Section 409A, in which case they shall be made on the first business day that is at least sixty-one (61) days following the Termination Date. 
 7.9 Parachute Payments. 
 (a) Notwithstanding any other provision in this Agreement, in the event any payments or benefits Executive receives or would become entitled to receive from the Company, any person whose actions result in
a Change in Control or any person affiliated with the Company or such person (in the aggregate, the “Payments”) would (i) constitute a “parachute payment” within the meaning of Section 280G of the Code,
and (ii) but for this sentence, be subject to the excise tax imposed by Section 4999 of the Code or any similar or successor provision (the “Excise Tax”), then the amount of the Payments shall be equal to either
(x) the largest portion of the Payments that would result in no portion of the Payments being subject to the Excise Tax (the “Reduced Amount”), or (y) the full amount of the Payments, whichever of the foregoing
amounts, after taking into account all applicable federal, state and local employment taxes, income taxes, and the Excise Tax (all computed at the highest marginal rate applicable to individuals in the year in which the Payments are to be made),
results in Executive’s receipt, on an after-tax basis, of the greatest amount of the Payments notwithstanding that all or some portion of the Payments may be subject to the Excise Tax. If a reduction in the Payments is required so that the
amount of the Payments equals the Reduced Amount, the Payments shall be reduced in the following order: (1) reduction of cash Payments otherwise payable to Executive that are exempt from Section 409A of the Code; (2) cancellation of
accelerated vesting of equity awards (other than stock options) that are exempt from Section 409A of the Code; (3) cancellation of accelerated vesting of stock options that are exempt from Section 409A of the Code; (4) reduction
of any other payments and benefits otherwise payable to Executive that are exempt from Section 409A of the Code; and (5) reduction of any other benefits and payments otherwise payable to Executive on a pro-rata basis or such other manner
that complies with Section 409A of the Code, as determined by the Company. If acceleration of vesting of Executive’s stock options or other equity awards is to be reduced pursuant to clauses

  

 -11- 








 
(2) or (3) of the immediately preceding sentence, such acceleration of vesting shall be cancelled by first canceling such acceleration for the vesting installment that will vest last and
continuing by canceling as a first priority such acceleration for the vesting installment with the latest vesting. 
 (b) All
computations and determinations called for by this Section 7.9 shall be made and reported in writing to the Company and Executive by an independent accounting firm or independent tax counsel appointed by the Company (the
“Tax Advisor”), and all such computations and determinations shall be conclusive and binding on the Company and Executive. For purposes of such calculations and determinations, the Tax Advisor may rely on reasonable,
good faith interpretations concerning the application of Sections 280G and 4999 of the Code. The Company and Executive shall furnish to the Tax Advisor such information and documents as the Tax Advisor may reasonably request in order to make their
required calculations and determinations. The Company shall bear all fees and expenses charged by the Tax Advisor in connection with its services. 
 7.10 Withholding 
 The Company may deduct from any amounts payable under
this Agreement, any amounts that it is required by law to withhold, including, without limitation, social security taxes, federal and state income taxes, and state disability insurance; provided, however, that any and all such obligations shall be
Executive’s responsibility. 
 8. Non-competition and Non-solicitation

 During the Term and for a period of twelve (12) months after the Termination Date, Executive shall not directly or indirectly work or otherwise engage in research, development, manufacture, sale or distribution of any product, method

 (b) For any research institution whose research efforts pertain to the same products manufactured or marketed by the Company during
Executive’s employment with the Company or under research or development by the Company during Executive’s employment with the Company (and on which the Company has expended at least $500,000), unless Executive is not involved in any
manner in the design, conduct or supervision of such research efforts, or unless such research is being conducted solely for scientific and not for commercial purposes. 
 Executive shall be deemed to be engaged in a business if such business is carried on by partnership in which Executive is a general or limited partner, consultant or employee, or a corporation or
association of which Executive is a shareholder, officer, director, employee, member, consultant or agent; provided, that nothing herein shall prevent the purchase or ownership by Executive of shares of less than one percent (1%) of the
outstanding shares in a publicly or privately held corporation. 
  

 -12- 








 Said twelve (12) months’ period shall commence on the day on which Executive
actually leaves Executive’s employment with the Company, even if this date is prior to the expiration of any given Notice of Termination.

whatsoever, arising out of any contracts, express or implied, any covenant of good faith and fair dealing, express or implied, any theory of wrongful discharge, any legal restriction on the Company’s right to terminate employment, or any
federal, state or other governmental statute or ordinance, including, without limitation, Title VII of the Civil Rights Act of 1964, the federal Age Discrimination in Employment Act, the Americans with Disabilities Act, the Family and Medical Leave
Act, the Washington Law Against Discrimination, or any other legal limitation on the employment relationship. Such release and waiver must be executed and effective (and the applicable revocation period must have expired without the release and
waiver being revoked) not more than sixty (60) days after the Termination Date or Executive shall not be entitled to any such payments or benefits. 
 (b) In addition, the payments and benefits contemplated by Section 7 (other than Accrued Obligations) are expressly contingent upon Executive’s full compliance with Executive’s obligations
towards the Company, including, without limitation, the terms of the Inventions Agreement and the non-competition provision of Section 8.1. In the event Executive materially breaches the Inventions Agreement or Section 8.1,
Executive’s right to any payments or benefits under Section 7 (including those that have already been made or provided), other than Accrued

  

 -13- 








 
Obligations, shall be forfeited and extinguished, regardless of whether the Company takes legal action or otherwise tries to enforce its rights. In such event, the Company shall cease payments,
and Executive shall immediately return to the Company any payments already made. The Company reserves all rights it may have under contract or law to relief or damages in addition to termination of the above-described payments. 
 10. Return of Materials 
 All documents, records, notebooks, notes, memoranda, drawings or other documents made or compiled by Executive at any time while employed by the Company, or in Executive’s possession, including any and all copies thereof, shall be the
property of the Company and shall be held by Executive in trust and solely for the benefit of the Company, and shall be delivered to the Company by Executive upon termination of employment or at any other time upon request by the Company.

 11. Notice and Cure of Breach 
 Except as provided otherwise in Section 7.5(b), whenever a breach of this Agreement by either party is relied upon as justification for any action taken by the other party pursuant to any provision
of this Agreement, other than clauses (a), (b), or (c) of Section 7.6, before such action is taken, the party asserting the breach of this Agreement shall give the other party at least twenty (20) days’ prior written notice of
the existence and the nature of such breach before taking further action hereunder and shall give the party purportedly in breach of this Agreement the opportunity to correct such breach during the twenty (20) day period. 
 12. No Violation of Other Agreements 
 In order to induce the Company to enter into this Agreement, Executive represents and warrants to the Company that neither the execution nor the performance of this Agreement by Executive shall violate or
conflict in any way with any other agreement or obligations by which Executive may be bound. 
 13. Rights of Assignment or Delegation 

 This Agreement is personal to Executive and shall not be assignable by Executive. The Company may assign its rights hereunder
to (a) any corporation resulting from any merger, consolidation, or other reorganization to which the Company is a party or (b) any corporation, partnership, association, or other person to which the Company may transfer all or
substantially all of the assets in business of the Company existing at such time. As used in this Agreement, “Company” shall mean ZymoGenetics, Inc. and any successor to its business and/or assets that assumes and agrees to
perform this Agreement by operation of law, or otherwise. All the terms and provisions of this Agreement shall be binding upon and shall inure to the benefit and be enforceable by the parties hereto and their respective heirs, legal or personal
representatives, successors and permitted assigns.

 14. Waiver 
 No delay or failure by any party in exercising, protecting or enforcing any of its rights, titles, interests, or remedies hereunder and no course of dealing or performance with respect thereto, shall
constitute a waiver. The express waiver by a party of any right, title, interest, or remedy in a particular instance or circumstance shall not constitute a waiver in any other instance or circumstance. All rights and remedies shall be cumulative and
not exclusive of any rights or remedies. 
 15. Arbitration 
 Any controversies or claims arising out of or relating to this Agreement shall be settled finally and fully by arbitration in Seattle, Washington in accordance with the Employment Arbitration Rules of the
American Arbitration Association then in effect (the “AAA Rules”), conducted by one arbitrator, mutually agreed upon by the Company and Executive or chosen in accordance with the AAA Rules, except the parties thereto shall have any right
to discovery that would be permitted by the Federal Rules of Civil Procedure for a period of ninety (90) days following the commencement of such arbitration and the arbitrator shall resolve any dispute which arises in connection with such
discovery. The prevailing parties shall be entitled to costs, expenses, reasonable attorneys’ fees, and judgment upon the award rendered by the arbitrator. The award may be entered in any court having jurisdiction. To the extent necessary to
prevent Executive from being subject to any additional tax pursuant to Code Section 409A(a)(1)(B), any amounts payable to Executive pursuant to this paragraph shall be paid in no event later than the year following the year during which such
costs and fees were incurred. 
 16. Amendments in Writing 
 No amendment, modification, waiver, termination or discharge of any provision of this Agreement, nor consent to any departure by either party, shall in any event be effective unless the same shall be in
writing, specifically identifying this Agreement and the provision intended to be amended, modified, waived, terminated, or discharged and assigned by the Company and Executive. Each such amendment, modification, waiver, termination, or discharge
shall be effective only in the specific instance and for the specific purpose for which given. No provision of this Agreement shall be varied, contradicted, or explained by any oral agreement, course of dealing or performance or any other matter not
set forth in agreement in writing and signed by the Company and Executive. 
 17. Notices

 -15- 








 To Executive: 
 Darren R. Hamby 
 2820 31st
Avenue W. 
 Seattle, WA 98199 
 or to such other address, as to either party, as such party shall from time to time designate by like notice to the other. 
 18. Entire Agreement 
 This Agreement supersedes and replaces the Original
Agreement and constitutes the entire agreement between the Company and Executive with respect to the subject matter hereof, and all prior or contemporaneous oral or written communications, understandings or agreements between the Company and
Executive with respect to such subject matter, are hereby superseded and nullified in their entireties, except that the Inventions Agreement shall continue in full force and effect. 
 19. Governing Law 
 This Agreement is made under and shall be governed by
and construed in accordance with the laws of the State of Washington (without regard to any rules governing conflict of laws), except to the extent preempted by Federal law. 
 20. Severability 
 If any provision of this Agreement shall be held invalid,
illegal or unenforceable in any jurisdiction, for any reason, including without limitation, the duration of such provision, its geographical scope or the extent of the activities prohibited or required by it, then, to the full extent permitted by
law (a) all other provisions hereof shall remain in full force and effect and such provision shall be liberally construed in order to carry out the intent of the parties as nearly as may be possible, (b) such invalidity, illegality, or
unenforceability shall not affect the validity, legality or enforceability of any other provision, and (c) any court or arbitrator having jurisdiction thereover shall have the power to reform such provision to the extent necessary for such
provision to be enforceable under applicable law. 
 21. 409A Interpretation Provision 
 The parties intend that this Agreement and the benefits provided hereunder be exempt from the requirements of Code Section 409A to the
maximum extent possible, whether pursuant to the short-term deferral exception described in Treasury Regulation Section 1.409A-1(b)(4), the involuntary separation pay plan exception described in Treasury Regulation
Section 1.409A-1(b)(9)(iii), or otherwise. To the extent Code Section 409A is applicable to this Agreement, the parties intend that this Agreement comply with the deferral, payout and other limitations and restrictions imposed under Code
Section 409A. Notwithstanding any other provision of this Agreement to the contrary, this Agreement shall be interpreted, operated and administered in a manner consistent with such intentions. Without limiting the generality of the foregoing,
and notwithstanding any other provision of this Agreement to the contrary, with respect to any

  

 -16- 








 
payments and benefits under this Agreement to which Code Section 409A applies, all references in this Agreement to the termination of Executive’s employment are intended to mean
Executive’s “separation from service,” within the meaning of Code Section 409A(a)(2)(A)(i). In addition, if Executive is a “specified employee,” within the meaning of Code Section 409A, then to the extent necessary
to avoid subjecting Executive to the imposition of any additional tax under Code Section 409A, amounts that would otherwise be payable under this Agreement during the six (6) month period immediately following Executive’s
“separation from service,” within the meaning of Code Section 409A(a)(2)(A)(i), shall not be paid to Executive during such period, but shall instead be accumulated and paid to Executive (or, in the event of Executive’s death,
Executive’s estate) in a lump sum on the first business day after the earlier of the date that is six (6) months following Executive’s separation from service or Executive’s death. If the Company or Executive determines that any
provision of this Agreement is or might be inconsistent with the requirements of Code Section 409A, the parties shall attempt in good faith to agree on such amendments to this Agreement as may be necessary or appropriate to avoid subjecting
Executive to the imposition of any additional tax under Code Section 409A. Notwithstanding the foregoing, no provision of this Agreement shall be interpreted or construed to transfer any liability for failure to comply with Code
Section 409A from Executive or any other individual to the Company or any of its affiliates. 
 22. Multiple Copies 
 This Agreement may be executed in two (2) or more counterparts of like tenor and effect, each of which shall be deemed an original but
all of which together shall constitute one and the same instrument. 
 IN WITNESS WHEREOF, the parties have executed and entered
into this Agreement as of the Effective Date.
