Right to Severance Benefits. The Executive shall be entitled to receive from the Company Severance Benefits if:

solely with respect to termination of Executive’s employment pursuant to 4.2(a), the Executive is not (i) offered employment by the Company or any subsidiary or affiliate of the Company whether in a salaried, hourly, temporary, or full-time capacity, or (ii) offered a contract to serve as a consultant or contractor by the Company or any subsidiary or affiliate of the Company, or (iii) offered employment or a contract to serve as a consultant or contractor by an entity acquiring the Company.

Qualifying Termination. The occurrence of any one or more of the following events within twenty-four (24) full calendar months following the effective date of a CIC of the Company shall trigger the payment of Severance Benefits to the Executive under this Agreement:

An involuntary termination of the Executive’s employment by the Company, authorized by the Company’s Senior Vice President overseeing Human Resources,

for reasons other than for Cause, mandatory Retirement under the Company’s applicable policies, or the Executive’s death, Disability, or voluntary termination of employment (including voluntary Retirement) without Good Reason; or  

a voluntary termination by the Executive for Good Reason.

Description of Severance Benefits. In the event that the Executive becomes entitled to receive Severance Benefits (and further contingent on the proper execution of the Non-Competition and Release Agreement as set forth in Section 4.8), as provided in Sections 4.1 and 4.2, the Company shall pay to the Executive and provide him with the following:

An amount equal to three (3) times the highest rate of the Executive’s annualized Base Salary rate in effect at any time up to and including the Effective Date of Termination.

An amount equal to three (3) times the Executive’s target annual bonus established for the bonus plan year in which the Executive’s Effective Date of Termination occurs (or, if higher, the target annual bonus established for the bonus plan year in which the CIC occurs).

An amount equal to the Executive’s unpaid Base Salary and accrued vacation pay through the Executive’s last day of work.

An amount equal to the Executive’s unpaid actual annual bonus, paid for the plan year in which the Executive’s Effective Date of Termination occurs, multiplied by a fraction, the numerator of which is the number of days completed in the then-existing fiscal year through the Effective Date of Termination and the denominator of which is three hundred sixty-five (365). Any payments hereunder are in lieu of any bonuses otherwise payable under the Company’s applicable annual incentive plans.

A lump sum payment of seventy-five thousand dollars ($75,000) (net of required payroll and income tax withholding) in order to assist the Executive in paying for replacement health and welfare coverage for a reasonable period following the Executive’s Effective Date of Termination.

Full vesting of the Executive’s benefits under any and all supplemental retirement plans in which the Executive participates. For purposes of determining the amount of an Executive’s benefits in such plans, such benefits shall be calculated under the assumption that the Executive’s employment continued following the Effective Date of Termination for three (3) full years (i.e., three (3) additional years of age and service credits shall be added); provided, however, that for purposes of determining “final average pay” under such programs, the Executive’s actual pay history as of the effective date of termination shall be used. Payout of such amounts shall occur at the time established under such plans.

To the extent that the Executive is subject to a reduction of such benefits due to application of any early retirement provisions, the three (3) additional years of age shall be incorporated in the early retirement reduction calculation so as to offset

such reduction. Also, three (3) additional years of age, but not any additional service, shall be used to determine the Executive’s eligibility for early retirement benefits.

Unless otherwise provided in the instrument evidencing the Equity Award or in a written employment or other agreement between the Executive and the Company and subject to the requirements of Section 409A of the Code, to the extent applicable:

Termination for Disability. Following a CIC of the Company, if the Executive’s employment is terminated due to Disability, no compensation or benefits shall be payable under this Agreement and the Executive shall instead receive his Base Salary through the Effective Date of Termination, at which point in time the Executive’s benefits shall be determined in accordance with the Company’s disability and other applicable compensation and benefits plans and programs then in effect.

Termination for Retirement or Death. Following a CIC of the Company, if the Executive’s employment is terminated by reason of his death or voluntary Retirement other than for Good Reason, no compensation or benefits shall be payable under this Agreement and the Executive’s benefits shall instead be determined in accordance with the Company’s retirement and other applicable compensation and benefits plans and programs then in effect.

Termination for Cause or by the Executive Other Than for Good Reason or Retirement. Following a CIC of the Company, if the Executive’s employment is terminated either (i) by the Company for Cause or (ii) by the Executive (other than for Disability or death) and other than for Good Reason, no compensation or benefits shall be payable under this Agreement and the Executive’s benefits shall instead be determined in accordance with the Company’s applicable compensation and benefits plans and programs then in effect.

Notice of Termination. Any termination by the Company or by the Executive for Good Reason under this Article 4 shall be communicated by a Notice of Termination, which shall be delivered to the Executive (or to the Senior Vice President overseeing Human Resources, as

applicable) no later than the Effective Date of Termination, unless the Executive is terminated for Cause, in which case no Notice of Termination is required. For purposes of this Agreement, a “Notice of Termination” shall mean a written notice that shall indicate the specific termination provision in this Agreement relied upon, and shall set forth in reasonable detail the facts and circumstances claimed to provide a basis for termination of the Executive’s employment under the provision so indicated.

Delivery of Non-Competition and Release Agreement. The payment of Severance Benefits is conditioned on the Executive’s timely execution of the Non-Competition and Release Agreement. The Company will deliver the Non-Competition and Release Agreement when it provides a Notice of Termination to the Executive or promptly following the Company’s receipt of a Notice of Termination from the Executive. The Non-Competition and Release Agreement shall be deemed effective upon the expiration of the required waiting periods under applicable state and/or federal laws as more specifically described therein.

Removal from Representative Boards.  In the event the terminating Executive occupies any board of directors seats solely as a Company representative, as a condition to receiving the severance set forth in Section 4.3 the Executive shall immediately resign such position upon Executive’s termination of employment with the Company and in any event by the deadline for returning the Non-Competition and Release Agreement described in Section 4.8, unless specifically requested in writing by the Company otherwise.

Form and Timing of Severance Benefits. The Severance Benefits described in Sections 4.3(a), 4.3(b), 4.3(c) and 4.3(e) shall be paid in cash to the Executive in a single lump sum, subject to the Non-Competition and Release Agreement referred to in Section 4.8, as soon as practicable following the Effective Date of Termination, but in no event beyond thirty (30) days from the later of the Effective Date of Termination and the successful expiration of the waiting periods described in Section 4.8 and in no event later than the payment deadline for short-term deferrals under Treas. Reg. § 1.409A-1(b)(4) (or any successor provision).  The Severance Benefit described in Section 4.3(d) shall be paid in cash to the Executive in a single lump sum, subject to the Non-Competition and Release Agreement described in Section 4.8, as soon as practicable following the end of the year in which the Executive’s Effective Date of Termination occurs and in no event later than the payment deadline for short-term deferrals under Treas. Reg. § 1.409A-1(b)(4) (or any successor provision), subject to any deferral election by the Executive under an available deferred compensation plan that is applicable to such amount.

Withholding of Taxes. The Company shall be entitled to withhold from any amounts payable under this Agreement all taxes as legally shall be required (including, without limitation, any United States federal taxes and any other state, city, or local taxes).

Payment Obligations Absolute. Except as provided in this Article 6 and Article 7, the Company’s obligation to make the payments and the arrangements provided for hereof shall be absolute and unconditional, and shall not be affected by any circumstances, including, without limitation, any offset, counterclaim, recoupment, defense, or other right that the Company may have against the Executive or anyone else. All amounts payable by the Company hereunder shall be paid without notice or demand. Except as provided in this Article 6 and in Article 7, each and every payment made hereunder by the Company shall be final, and the Company shall not seek to recover all or any part of such payment from the Executive or from whosoever may be entitled thereto, for any reasons whatsoever.  

Contractual Rights to Benefits. Subject to Article 1 and Section 6.3, this Agreement establishes and vests in the Executive a contractual right to the benefits to which he may become entitled hereunder. However, nothing herein contained shall require or be deemed to require, or prohibit or be deemed to prohibit, the Company to segregate, earmark, or otherwise set aside any funds or other assets, in trust or otherwise, to provide for any payments to be made or required hereunder.

Forfeiture of Severance Benefits and Other Payments. Notwithstanding any other provision of this Agreement to the contrary, if it is determined by the Company that the Executive has violated any of the restrictive covenants contained in the Executive’s Non-Competition and Release Agreement, the Executive shall be required to repay to the Company an amount equal to the economic value of all Severance Benefits and other payments already provided to the Executive under this Agreement and the Executive shall forever forfeit the Executive’s rights to any unpaid Severance Benefits and other payments hereunder.  The Severance Benefits shall be subject to (a) forfeiture provisions in any other agreements between the Executive and the Company, and (b) any recoupment, clawback or similar policy of the Company as it may be in effect from time to time, as well as any similar provisions of applicable law, any of which could in certain circumstances require repayment or forfeiture of previously paid compensation.

Claims Procedure.  The Executive may file a written claim with the Company’s Senior Vice President overseeing Human Resources, who shall consider such claim and notify the Executive in writing of his or her decision with respect thereto within ninety (90) days (or within such longer period not to exceed one hundred eighty (180) days, as the Senior Vice President overseeing Human Resources determines is necessary to review the claim, provided that the Senior Vice President overseeing Human Resources notifies the Executive in writing of the extension within the original ninety (90) day period).  If the claim is denied, in whole or in part, the Executive may appeal such denial to the Committee, provided the Executive does so in writing within sixty (60) days of receiving the determination by the Senior Vice President overseeing Human Resources.  The Committee shall consider the appeal and notify the Executive in writing of its decision with respect thereto within sixty (60) days (or within such longer period not to exceed one hundred twenty (120)

days as the Committee determines is necessary to review the appeal, provided that the Committee notifies the Executive in writing of the extension within the original sixty (60) day period).  

Finality of Determination.  The determination of the Committee with respect to any question arising out of or in connection with the administration, interpretation, and application of this Agreement shall be final, binding, and conclusive on all persons and shall be given the greatest deference permitted by law.

Successors to the Company. The Company will require any successor (whether direct or indirect, by purchase, merger, consolidation, or otherwise) of all or substantially all of the business and/or assets of the Company or of any division or subsidiary thereof to expressly assume and agree to perform the Company’s obligations under this Agreement in the same manner and to the same extent that the Company would be required to perform them if no such succession had taken place. Failure of the Company to obtain such assumption and agreement prior to the effective date of any such succession shall be a material breach of this Agreement and shall entitle the Executive to compensation from the Company in the same amount and on the same terms as he would be entitled to hereunder if he had terminated his employment with the Company voluntarily for Good Reason.

For the purposes of implementing the foregoing, the date on which any such succession becomes effective shall be deemed the Effective Date of Termination.

Assignment by the Executive. This Agreement shall inure to the benefit of and be enforceable by each Executive’s personal or legal representatives, executors, administrators, successors, heirs, distributees, devisees, and legatees. If the Executive dies while any amount would still be payable to him hereunder had he continued to live, all such amounts, unless otherwise provided herein, shall be paid in accordance with the terms of this Agreement to the Executive’s Beneficiary. If the Executive has not named a Beneficiary, then such amounts shall be paid to the Executive’s devisee, legatee, or other designee, or if there is no such designee, to the Executive’s estate.

Employment Status. Except as may be provided under any other agreement between the Executive and the Company, the employment of the Executive by the Company is “at will” and, prior to the effective date of a CIC, may be terminated by either the Executive or the Company at any time, subject to applicable law.  

Beneficiaries. The Executive may designate one or more persons or entities as the primary and contingent Beneficiaries of any Severance Benefits owing to the Executive under this Agreement. Such designation must be in the form of a signed writing acceptable to the Committee and pursuant to such other procedures as the Committee may decide.  If no such designation is on file with the Company at the time of the Executive’s death, or if no designated Beneficiaries survive the Executive for more than fourteen (14) days, any Severance Benefits owing to the Executive under this Agreement shall be paid to the Executive’s estate.

Gender and Number. Except where otherwise indicated by the context, any masculine term used herein also shall include the feminine, the plural shall include the singular, and the singular shall include the plural.

Severability. In the event any provision of this Agreement shall be held illegal or invalid for any reason, the illegality or invalidity shall not affect the remaining parts of this Agreement, and this Agreement shall be construed and enforced as if the illegal or invalid provision had not been included. Further, the captions of this Agreement are not part of the provisions hereof and shall have no force and effect.

Modification. Except as provided in Article 1, no provision of this Agreement may be modified, waived, or discharged following a CIC unless such modification, waiver, or discharge is agreed to in writing and signed by the Executive and by an authorized member of the Committee, or by the respective parties’ legal representatives and successors.  

Effect of Agreement. This Agreement shall completely supersede and replace any and all portions of any contracts, plans, provisions, or practices pertaining to severance entitlements owing to the Executive from the Company other than the Severance Agreement, and is in lieu of any notice requirement, policy, or practice. As such, the Severance Benefits described herein shall serve as the Executive’s sole recourse with respect to termination of employment by the Company following a CIC.  In addition, Severance Benefits shall not be counted as “compensation,” or any equivalent term, for purposes of determining benefits under other agreements, plans, provisions, or

practices owing to the Executive from the Company, except to the extent expressly provided therein. Except as otherwise specifically provided for in this Agreement, the Executive’s rights under all such agreements, plans, provisions, and practices continue to be subject to the respective terms and conditions thereof.

Applicable Law. To the extent not preempted by the laws of the United States, the laws of the state of Washington shall be the controlling law in all matters relating to this Agreement.
