(ii) Any merger or consolidation of the Company with any other corporation that has been approved by the stockholders of the Company, other than a merger or consolidation which would result in the voting securities of the Company outstanding immediately prior thereto continuing to represent (either by remaining outstanding or by being converted into voting securities of the surviving entity) more than fifty percent (50%) of the total voting power represented by the voting securities of the Company or such surviving entity outstanding immediately after such merger or consolidation, or the stockholders of the Company approve a plan of complete liquidation of the Company;

4. At-Will Employment. Subject to the terms and conditions hereof including without limitation Sections 6 and 7, the Company and the Employee acknowledge that the Employee’s employment is and shall continue to be terminable at-will, either party able to terminate the employment relationship with or without Cause.

5. Compensation and Benefits

(iii) the same level of health (i.e., medical, vision and dental) coverage and benefits as in effect for the Employee on the day immediately preceding the Termination Date; provided, however, that (A) the Employee constitutes a qualified beneficiary, as defined in Section 4980B(g)(1) of the Internal Revenue Code of 1986, as amended (the “Code”); and (B) Employee elects continuation coverage pursuant to the Consolidated Omnibus Budget Reconciliation Act of 1985, as amended (“COBRA”), within the time period prescribed pursuant to COBRA.

(iv) Fifty percent (50%) of the Employee’s then unvested stock options shall immediately vest and become exercisable and Employee shall have twelve (12) months following the Termination Date to exercise such vested shares and fifty percent (50%) of the Employee’s then unvested restricted stock units (RSUs) shall immediately vest; provided, however, that in the event of a conflict between the terms and conditions of any such stock option agreement or Notice of Grant of Restricted Stock Units and Restricted Stock Unit Agreement, as the case may be, and this Agreement, the terms and conditions of this Agreement shall prevail unless the conflicting provision(s) in any such stock option agreement or Notice of Grant of Restricted Stock Units and Restricted Stock Unit Agreement, as the case may be, shall be more favorable to Employee in which case the provision(s) more favorable to Employee shall govern; provided further, however, that notwithstanding the foregoing in no event shall the extended twelve (12) month exercise period specified in this Section 6(b)(iv) modify or extend the Expiration Date of any stock option as set forth in such stock option agreement.

(d) Death. In the event of Employee’s death while employed hereunder, Employee’s beneficiary (or such other person(s) specified by will or the laws of descent and distribution) will receive (i) continuing payments of severance pay (less applicable withholding taxes) at a rate equal to Employee’s base salary for a period of ninety (90) days from Employee’s death, to be paid periodically in accordance with the Company’s normal payroll policies, (ii) Company-paid COBRA benefits as specified in Section 6(b)(iii) above for ninety (90) days from Employee’s death, and (iii) have the right to exercise Employee’s stock options which are vested as of the date of Employee’s death for one (1) year following Employee’s death.

7. Change of Control Benefits. If Employee (i) is terminated other than for Cause by the Company within ninety (90) days prior to a Change of Control or as a result of or in connection with a Change of Control or (ii) is terminated other than for Cause by the Company (or its successor corporation) or resigns for Good Reason within twelve (12) months following a Change of Control, and provided that Employee signs and does not revoke a Release, then Employee shall be entitled to the same benefits as set forth in Sections 6(b)(i) through 6(b)(iv) above.

Notwithstanding the foregoing, in the event that the benefits provided for in this Section 7 (i) constitute “parachute payments” within the meaning of Section 280G of the Code, and (ii) would be subject to the excise tax imposed by Section 4999 of the Code (the “Excise Tax”), then Employee’s benefits otherwise payable under this Section 7 shall be reduced by the minimum extent necessary such that no portion of such benefits would be subject to the Excise Tax. Unless the Company and Employee otherwise agree in writing, any determination required under this Section 7 shall be made in writing by the Company’s independent public accountants (the “Accountants”), whose determination shall be conclusive and binding upon Employee and the Company for all purposes. For purposes of making the calculations required by this Section 7, the Accountants may make reasonable assumptions and approximations concerning applicable taxes and may rely on reasonable, good faith interpretations concerning the application of Section 280G and 4999 of the Code. The Company and Employee shall furnish to the Accountants such information and documents as the Accountants may reasonably request in order to make a determination under this Section 7. The Company shall bear all costs the Accountants may reasonably incur in connection with any calculations contemplated by this Section 7. Any reduction in payments and/or benefits required by this Section 7 shall occur in the following order unless the Employee elects in writing a different order prior to the date on which the event that triggers the severance payments and benefits due hereunder occurs: (1) reduction of cash payments; and (2) reduction of other benefits paid to the Employee. In the event that acceleration of vesting of equity award compensation is to be reduced, such acceleration of vesting shall be cancelled in the reverse order of the date of grant for the Employee’s equity awards unless the Employee elects in writing a different order for cancellation prior to the triggering event.

8. No Impediment to Agreement. Employee hereby represents to the Company that Employee is not, as of the date hereof, and will not be during Employee’s employment with the Company, employed under contract, oral or written, by any other person, firm or entity, and is not and will not be bound by the provisions of any restrictive covenant or confidentiality agreement which would constitute an impediment to, or restriction upon, Employee’s ability to enter this Agreement and to perform the duties of Employee’s employment.

9. Supplementary Terms of Employment. Employee agrees, as a condition to Employee’s employment with the Company, to execute the Company’s standard form of Supplementary Terms of Employment attached hereto as Exhibit A.

10. Reserved.

11. Successors; Personal Services. The services and duties to be performed by the Employee hereunder are personal and may not be assigned or delegated. This Agreement shall be binding upon and inure to the benefit of the Company and its successors and assigns, and the Employee and Employee’s heirs and representatives.

12. Notices. Notices and all other communications contemplated by this Agreement shall be in writing and shall be deemed to have been duly given when personally delivered or when mailed by U.S. registered or certified mail, return receipt requested and postage prepaid. In the case of the Employee, mailed notices shall be addressed to Employee at the home address, which Employee most recently communicated to the Company in writing, with a copy to Employee’s counsel as designated by Employee whose address is provided below. In the case of the Company, mailed notices shall be addressed to its corporate headquarters, and all notices shall be directed to the attention of its General Counsel.

13. Code Section 409A.

(a) Notwithstanding anything to the contrary in this Agreement, if the Employee is a “specified employee” within the meaning of Section 409A of the Code, and the final regulations and any guidance promulgated thereunder (“Section 409A”) at the time of the Employee termination of employment (other than due to death), then the severance benefits payable to the Employee under this Agreement, if any, and any other severance payments or separation benefits that may be considered deferred compensation under Section 409A (together, the “Deferred Compensation Separation Benefits”) otherwise due to the Employee on or within the six (6) month period following the Termination Date will accrue during such six (6) month period and will become payable in a lump sum payment (less applicable withholding taxes) on the date six (6) months and one (1) day following the Termination Date. All subsequent payments, if any, will be payable in accordance with the payment schedule applicable to each payment or benefit. Notwithstanding anything herein to the contrary, if the Employee dies following his or her termination of employment but prior to the six (6) month anniversary of the Termination Date, then any payments delayed in accordance with this paragraph will be payable in a lump sum (less applicable withholding taxes) to the Employee’s estate as soon as administratively practicable after the date of the Employee’s death and all other Deferred Compensation Separation Benefits will be payable in accordance with the payment schedule applicable to each payment or benefit.

(b) This provision is intended to comply with the requirements of Section 409A so that none of the severance payments and benefits to be provided hereunder will be subject to the additional tax imposed under Section 409A, and any ambiguities herein will be interpreted to so comply. The Company and the Employee agree to work together in good faith to consider amendments to this Agreement and to take such reasonable actions which are necessary, appropriate or desirable to avoid imposition of any additional tax or income recognition prior to actual payment to the Employee under Section 409A.

(b) Entire Agreement. This Agreement (including exhibits) shall supersede and replace all prior agreements or understandings relating to the subject matter hereof, and no agreements, representations or understandings (whether oral or written or whether express or implied) which are not expressly set forth in this Agreement have been made or entered into by either party with respect to the relevant matter hereof.

(c) Choice of Law. The validity, interpretation, construction and performance of this Agreement shall be governed by the internal substantive laws of the State of Washington without reference to any choice of law rules.

The Company may assign its rights under this Agreement to an affiliate (as defined under the Securities Exchange Act of 1934), and an affiliate may assign its rights under this Agreement to another affiliate of the Company or to the Company. In the case of any such assignment, the term “Company” when used in a section of this Agreement shall mean the corporation that actually employs the Employee.

(i) Counterparts. This Agreement may be executed in counterparts, each of which shall be deemed an original, but all of which together will constitute one and the same instrument.
