b. Severance Consideration. The consideration set forth in this Section 1(b) is
referred to collectively as the Severance Consideration.

(i) Severance Payment. The Company agrees to pay
Executive, in a single lump sum cash payment, an amount equal to one million five hundred and seventy-five thousand dollars ($1,575,000), less applicable withholding, on the Companys first payroll date occurring after the Effective Date (as
defined below in Section 25) of this Agreement, which reflects eighteen (18) months of salary and target annual incentive bonus.

(ii) Pro-Rata Incentive Bonus. The Company agrees to pay Executive, in a single lump sum cash payment, an amount equal to one hundred and fifty-three thousand and one hundred and twenty-five
dollars ($153,125), less applicable withholding, on the Companys first payroll date occurring after the Effective Date, which reflects the pro-rata portion of Executives annual incentive bonus for the year of the Separation Date.

(iii) Cash Retention Award. The Company agrees to pay Executive, in a single lump cash payment, an amount equal to
two hundred and eight-three thousand dollars ($283,000), less applicable withholding, on the Companys first payroll date occurring after the Effective Date, which reflects the unvested portion of the retention payment set forth in the
Retention Agreement.

(iv) Equity Awards. The Company agrees that, to the extent not already fully vested, the vesting
of each Equity Award listed on Appendix A shall be fully accelerated as of the Separation Date. The Company intends that Appendix A includes all of the outstanding stock options and restricted stock units granted to Executive. Each of
Executives stock option awards listed on Appendix A shall be amended, to the extent necessary, so as to provide Executive with a period equal to the lesser of (A) eighteen (18) months after the end of the consulting period described
below in Section 1(b)(vi), or (B) the remaining term of the stock option to exercise such stock options. For example, if such stock options had been granted with a ten (10) year maximum term, then Executive would have until the end of
such maximum term or eighteen (18) months from the end of the consulting period, whichever is less, to exercise such stock options. The Equity Awards shall in all other respects remain subject to all of the other terms and conditions of the
applicable Stock Agreements (as amended and/or modified by the terms of the Severance Agreement or Retention Agreement).

(v)
Benefits. The Company agrees to reimburse Executive for premiums incurred to continue group health benefits for Executive, his spouse and any children, provided the Executive makes the appropriate health continuation election pursuant to the
Consolidated Omnibus Budget Reconciliation Act of 1985 (COBRA), until the first to occur of (A) eighteen (18) months following the Separation Date, or (B) the date Executive obtains comparable coverage. The Company will
make the reimbursements described in the preceding sentence on a monthly basis. Notwithstanding anything to the contrary in this Section 1(b)(v), if the Company determines in its sole discretion that it cannot provide the COBRA benefits without
potentially violating applicable law (including, without limitation, Section 2716 of the Public Health Service Act), the Company will in lieu thereof provide to Executive a taxable monthly payment in an amount equal to the monthly COBRA premium
that Executive would be required to pay to continue his group health coverage in effect on the date of his termination of employment (which amount will be based on the premium for the first month of COBRA coverage), which payments will be made
regardless of whether Executive elects COBRA continuation coverage and will end on the earlier of (x) the date upon which Executive becomes covered under similar plans or (y) the last day of the eighteenth (18th) calendar month
following the month in which Executive terminations employment.

(vi) Consulting Services. Executive shall serve as a consultant, as reasonably
requested by the Company to assist with an orderly transition of duties and responsibilities, for a period of three (3) months following the Separation Date. Executive will be compensated at a monthly rate equal to forty-three thousand and six
hundred and sixty-six dollars ($43,666) per month. The Company will also reimburse Executive for any related business expenses in accordance with standard Company policies. Executive will make himself reasonably available to provide the consulting
services, but notwithstanding anything to the contrary in this Agreement, Executive shall not be required to perform any services under the Consulting Agreement that would result in Executive providing services at a level greater than twenty percent
(20%) of the average level of services Executive performed for the Company during the thirty-six (36) month period immediately preceding the Separation Date.

c. Executive specifically acknowledges that Executive is not entitled to receive any additional severance, termination payments, wages, bonus or other form of compensation from the Company.

2. Benefits. Executives health insurance benefits will cease on the last day of April 2011, subject to Executives
right to continue his health insurance under COBRA. Executives participation in all benefits and incidents of employment, including, but not limited to, the accrual of bonuses, vacation, and paid time off, ceased as of the Separation Date.

3. Payment of Salary and Receipt of All Benefits. Executive acknowledges and represents that, other than the
consideration set forth in this Agreement, the Company has paid or provided all salary, wages, bonuses, accrued vacation/paid time off, premiums, leaves, housing allowances, relocation costs, interest, severance, outplacement costs, fees,
reimbursable expenses, commissions, stock, stock options, vesting, and any and all other benefits and compensation due to Executive.

4. Release of Claims. Executive agrees that the foregoing consideration represents settlement in full of all outstanding obligations owed to Executive by the Company and its current and former
officers, directors, employees, agents, investors, attorneys, shareholders, administrators, affiliates, benefit plans, plan administrators, insurers, trustees, divisions, and subsidiaries, and predecessor and successor corporations and assigns
(collectively, the Releasees). Executive, on his own behalf and on behalf of his respective heirs, family members, executors, agents, and assigns, hereby and forever releases the Releasees from, and agrees not to sue concerning, or in
any manner to institute, prosecute, or pursue, any claim, complaint, charge, duty, obligation, or cause of action relating to any matters of any kind, whether presently known or unknown, suspected or unsuspected, that Executive may possess against
any of the Releasees arising from any omissions, acts, facts, or damages that have occurred up until and including the date Executive signs this Agreement, including, without limitation:

relationship;

Executive agrees that the release set forth in this section shall be and remain in effect in all respects as a complete general release as to the matters released. This release does not extend to any
obligations incurred under this Agreement or to Executives vested rights in retirement or similar plans, programs or accounts. This release does not release claims that cannot be released as a matter of law, including, but not limited to,
Executives right to file a charge with or participate in a charge by the Equal Employment Opportunity Commission, or any other local, state, or federal administrative body or government agency that is authorized to enforce or administer laws
related to employment, against the Company (with the understanding that any such filing or participation does not give Executive the right to recover any monetary damages against the Company; Executives release of claims herein bars Executive
from recovering such monetary relief from the Company).

In addition, nothing in this release shall (i) operate to
release or waive Executives rights, if any, under contract, law, as an employee, officer or director of the Company, to be defended and indemnified by the Company against, any and all liability incurred with respect to any claim or proceeding
to which Executive is or is threatened to be made a party because of Executives service as an employee, officer or director, or Chairman of the Board of the Company, or (ii) operate to release or waive Executives rights, as an
employee, officer or director of the Company, to be named, protected by and have coverage rights under the Companys insurance policies.

As a condition to receiving the Severance Consideration, within seven (7) days after the Separation Date, Executive agrees to sign and return to the Company the form of Release of Claims Agreement
attached hereto as Appendix B (the Release Agreement). If Executive revokes such Release Agreement he shall not be entitled to any Severance Consideration.

5. Acknowledgment of Waiver of Claims under ADEA. Executive understands and
acknowledges that he is waiving and releasing any rights he may have under the Age Discrimination in Employment Act of 1967 (ADEA), and that this waiver and release is knowing and voluntary. Executive understands and agrees that this
waiver and release does not apply to any rights or claims that may arise under the ADEA after the Effective Date of this Agreement. Executive understands and acknowledges that the consideration given for this waiver and release is in addition to
anything of value to which Executive was already entitled.

Executive further understands and acknowledges that he has been
advised by this writing that: (a) he should consult with an attorney prior to executing this Agreement; (b) he has twenty-one (21) days within which to consider and sign this Agreement; (c) he has seven (7) days
following his execution of this Agreement to revoke this Agreement; (d) this Agreement shall not be effective until after the revocation period has expired; and (e) nothing in this Agreement prevents or precludes Executive from challenging
or seeking a determination in good faith of the validity of this waiver under the ADEA, nor does it impose any condition precedent, penalties, or costs for doing so, unless specifically authorized by federal law. In the event Executive signs this
Agreement and returns it to the Company in less than the 21-day period identified above, Executive hereby acknowledges that he has freely and voluntarily chosen to waive the time period allotted for considering this Agreement. Executive acknowledges
and understands that revocation must be accomplished by a written notification to the Companys Corporate Secretary at 2601 Elliott Avenue, Seattle, Washington, 98121, that is received prior to the Effective Date. The Parties agree that changes
to this Agreement, whether material or immaterial, do not restart the running of the 21-day period.

6. Unknown Claims.
Executive acknowledges that he has been advised to consult with legal counsel and that he is familiar with the principle that a general release does not extend to claims that the releaser does not know or suspect to exist in his favor at the time of
executing the release, which, if known by him, must have materially affected his settlement with the released party. Executive being aware of said principle agrees to expressly waive any rights he may have to that effect, as well as under any other
statute or common law principles of similar effect.

7. No Pending or Future Lawsuits. Executive and the Company
represent that they have no lawsuits, claims, or actions pending in their respective names, or on behalf of any other person or entity, against each other, or in Executives case, against any of the Releasees. Executive also represents that he
does not intend to bring any claims on his own behalf or on behalf of any other person or entity against the Releasees. The Company represents that as of the Effective Date of this Agreement, the Company and its directors and executive officers do
not intend to bring against Executive, any claim, complaint, charge, duty, obligation, or cause of action of any kind or nature. If, within one year following the Separation Date, the Company commences any formal arbitration or other formal legal
proceeding in a court of law against Executive, Executive shall be relieved of any and all of the obligations under Sections 10(a) and 12 of this Agreement.

8. Confidentiality. Executive agrees to maintain in complete confidence the existence of this Agreement, the contents and terms of this Agreement, and the consideration for this Agreement
(hereinafter collectively referred to as Separation Information). Except as required by law or as provided below in this Section 8, Executive may disclose Separation Information only to his immediate family members, the Court in any
proceedings to enforce the terms of this Agreement, Executives undersigned counsel, and Executives accountant and any professional tax advisor to the extent that they need to know the Separation Information in order to provide advice on
tax treatment or to prepare tax returns, and must prevent disclosure of any Separation Information to all other third parties. Executive agrees that he will not publicize, directly or indirectly, any Separation Information.

Executive acknowledges and agrees that the confidentiality of the Separation Information is
of the essence. The Parties agree that if the Company proves that Executive breached this Confidentiality provision, the Company shall be entitled to an award of its costs spent enforcing this provision, including all reasonable attorneys fees
associated with the enforcement action, without regard to whether the Company can establish actual damages from Executives breach, except to the extent that such breach constitutes a legal action by Executive that directly pertains to the
ADEA. Any such individual breach or disclosure shall not excuse Executive from his obligations hereunder, nor permit him to make additional disclosures. Executive warrants that he has not disclosed, orally or in writing, directly or indirectly, any
of the Separation Information to any unauthorized party.

Prior to the disclosure of this Agreement pursuant to any applicable
securities laws, the Company agrees to keep the Separation Information confidential except for legitimate business reasons on a need-to-know basis. Notwithstanding the foregoing, if the Company discloses Separation Information in any press release,
public securities filing or otherwise (except to Company employees, agents and advisors), then Executive may disclose or discuss any Separation Information that the Company has disclosed.

9. Confidentiality Agreement. Executive agrees to abide by the terms of the Confidentiality Agreement, specifically including the
provisions therein regarding nondisclosure of the Companys trade secrets and confidential and proprietary information. Executives signature below constitutes his acknowledgement and agreement that upon the Companys request, he
shall promptly return all documents and other items provided to Executive by the Company, developed or obtained by Executive in connection with his employment with the Company, or otherwise belonging to the Company.

10. No Cooperation With Third Parties.

a. Executive agrees that he will not counsel or assist any attorneys or their clients in the presentation or prosecution of any disputes, differences, grievances, claims, charges, or complaints by any
third party against the Company and/or any officer, director, employee, agent, representative, shareholder or attorney of the Company, unless under a subpoena, court order, or other legal obligation to do so.

b. Executive agrees to immediately notify the General Counsel of the Company upon receipt of any court order, subpoena, or any legal
discovery device that seeks or might require the disclosure or production of the existence or terms of this Agreement, and to furnish, within three (3) business days of its receipt, a copy of such subpoena or legal discovery device to the
Company. The Company agrees to immediately notify Executive upon receipt of any court order, subpoena, or any legal discovery device that seeks or might require the disclosure or production of the existence or terms of this Agreement, and to
furnish, within three (3) business days of its receipt, a copy of such subpoena or legal discovery device to Executive.

11. Cooperation with Company. Executive agrees that Executive shall reasonably cooperate with the Company in the resolution of any
matters in which Executive was involved in during the course of Executives employment, or about which Executive has knowledge, and in the defense or prosecution of any claims or actions now in existence or which may be brought or threatened in
the future against or on behalf of the Company, including any claims or actions against its officers, directors and employees.

Executives cooperation in connection with such matters, actions and claims shall include, without limitation, being available to
consult with the Company regarding matters in which Executive has been involved or has knowledge; to assist the Company in preparing for any proceeding (including, without limitation, depositions, consultation, discovery or trial); to provide
affidavits reflecting truthful written testimony; to assist with any audit, inspection, proceeding or other inquiry; and to act as a witness to provide truthful testimony in connection with any litigation or other legal proceeding affecting the
Company. Executive agrees to keep the Company apprised of his current contact information, including telephone numbers, work address, home address, and email address(es), and to promptly respond to communications from the Company in connection with
this Section 11. Executive further



Page 6 of 15

agrees that should Executive be contacted (directly or indirectly) by any person or entity adverse to the Company, or any representative of such person or entity, Executive shall promptly, and no
later than within 48 hours of such contact, notify the Chief Executive Officer and General Counsel of the Company (or in the absence of a Chief Executive Officer, notify the President of the Company, and in the absence of a General Counsel, notify
the Deputy General Counsel of the Company).

The Company agrees to compensate Executive for all reasonable time incurred
pursuant to this Section 11 at a rate of $550 per hour. Executive shall also be reimbursed for any documented and reasonable costs and expenses incurred in connection with providing such cooperation under this Section.

12. Non-Disparagement, No-Hire, Non-Solicitation and Non-Competition. As a condition of receiving the Severance Consideration,
Executive agrees to remain subject to the Non-Disparagement, No-Hire and Non-Solicitation provisions of Section 4(b) of the Severance Agreement; provided, however, that the Non-Disparagement provision will not apply to any statements
that Executive makes in addressing any disparaging statements made by the Company, its officers and/or its directors regarding Executive or Executives performance as an employee of the Company so long as Executives statements are
truthful. The Company shall instruct its officers and directors to refrain from any disparaging statements about Executive for the same period for which Executive is subject to a Non-Disparagement requirement under this Section 12 and subject
to Section 7; provided, however, that the Non-Disparagement provision will not apply to any statements that Company or its officers and directors make in addressing any disparaging statements made by Executive regarding the Company or
its officers and directors so long as such statements are truthful.

As a further condition of receiving the Severance
Consideration, Executive agrees for a period of one year following the Separation Date, Executive will not, either directly or indirectly, (i) serve as an advisor, agent, consultant, director, employee, officer, partner, proprietor or otherwise
of, (ii) have any ownership interest in (except for passive ownership of one percent (1%) or less of any entity whose securities have been registered under the Securities Act of 1933, as amended, or Section 12 of the Securities
Exchange Act of 1934, as amended) or (iii) participate in the organization, financing, operation, management or control of, any business in competition with the Companys business as conducted by the Company as of the Separation Date. The
foregoing covenant shall cover Executives activities in every part of the Territory. Territory shall mean (i) all counties in the State of Washington, (ii) all other states of the United States of America and
(iii) all other countries of the world.

The covenants contained in this Section 12 shall be construed as a series
of separate covenants, one for each city, county and state of any geographic area in the Territory. Except for geographic coverage, each such separate covenant shall be deemed identical in terms to the covenant contained in this Section 12. If,
in any judicial proceeding, a court refuses to enforce any of such separate covenants (or any part thereof), then such unenforceable covenant (or such part) shall be eliminated from this Agreement to the extent necessary to permit the remaining
separate covenants (or portions thereof) to be enforced. In the event the provisions this Section 12 are deemed to exceed the time, geographic or scope limitations permitted by applicable law, then such provisions shall be reformed to the
maximum time, geographic or scope limitations, as the case may be, then permitted by such law.

13. Breach. Executive
acknowledges and agrees that any material breach of this Agreement, unless such breach constitutes a legal action by Executive challenging or seeking a determination in good faith of the validity of the waiver herein under the ADEA, or of any
provision of the Confidentiality Agreement, shall entitle the Company immediately to recover and/or cease providing the Severance Consideration provided to Executive under this Agreement and to obtain damages, except as provided by law.

14. No Admission of Liability. Executive understands and acknowledges that this
Agreement constitutes a compromise and settlement of any and all actual or potential disputed claims by Executive. No action taken by the Company hereto, either previously or in connection with this Agreement, shall be deemed or construed to be
(a) an admission of the truth or falsity of any actual or potential claims or (b) an acknowledgment or admission by the Company of any fault or liability whatsoever to Executive or to any third party.

15. Costs. The Parties shall each bear their own costs, attorneys fees, and other fees incurred in connection with the
preparation of this Agreement.

16. Jurisdiction; Venue. The parties agree that any and all disputes arising out of the
terms of this Agreement, their interpretation and any matters governed by this Agreement, shall be resolved in a court of competent jurisdiction in King County, Washington. The parties irrevocably consent to personal and exclusive jurisdiction and
venue in the state and federal courts in King County, Washington.

17. Tax Consequences. The Company makes no
representations or warranties with respect to the tax consequences of the Severance Consideration and any other consideration provided to Executive or made on his behalf under the terms of this Agreement. Executive agrees and understands that he is
responsible for payment, if any, of local, state, and/or federal taxes on the payments and any other consideration provided hereunder by the Company and any penalties or assessments thereon. Executive further agrees to indemnify and hold the Company
harmless from any claims, demands, deficiencies, penalties, interest, assessments, executions, judgments, or recoveries by any government agency against the Company for any amounts claimed due on account of (a) Executives failure to pay
or the Companys failure to properly withhold, or Executives delayed payment of, federal or state taxes, or (b) damages sustained by the Company by reason of any such claims, provided that the Company will not seek indemnification
from Executive until after Executive has been adjudicated by a court of competent jurisdiction to have failed to pay or improperly delayed payment of any taxes.

18. Authority. The Company represents and warrants that the undersigned has the authority to act on behalf of the Company and to bind the Company and all who may claim through it to the terms and
conditions of this Agreement. Executive represents and warrants that he has the capacity to act on his own behalf and on behalf of all who might claim through him to bind them to the terms and conditions of this Agreement. Executive warrants and
represents that there are no liens or claims of lien or assignments in law or equity or otherwise of or against any of the claims or causes of action released herein.

19. No Representations. Executive represents that he has had an opportunity to consult with an attorney, and has carefully read and understands the scope and effect of the provisions of this
Agreement. Executive has not relied upon any representations or statements made by the Company that are not specifically set forth in this Agreement.

20. Severability. In the event that any provision or any portion of any provision hereof or any surviving agreement made a part hereof becomes or is declared by a court of competent jurisdiction or
arbitrator to be illegal, unenforceable, or void, this Agreement shall continue in full force and effect without said provision or portion of provision.

21. Section 409A. Any amount paid under this Agreement that satisfies the requirements of the short-term deferral rule set forth in Section 1.409A-1(b)(4) of the final
treasury regulations issued under Section 409A of the Code (the Treasury Regulations) shall not constitute deferred compensation for purposes of Section 409A of the Code. Each payment and benefit payable under this Agreement is
intended to constitute separate payments for purposes of Section 1.409A-2(b)(2) of the Treasury Regulations. Any amount paid under this Agreement that qualifies as a payment made as a result of an involuntary separation from service pursuant to
Section 1.409A-1(b)(9)(iii) of the Treasury Regulations that does not exceed the Section 409A Limit (as defined below) shall not constitute deferred compensation subject to Section 409A of the Code. For purposes of this



Page 8 of 15



---

Section 21, Section 409A Limit will mean the lesser of two (2) times: (i) Executives annualized compensation based upon the annual rate of pay paid to Executive
during the Companys taxable year preceding the Companys taxable year of Executives termination of employment as determined under Treasury Regulation 1.409A-1(b)(9)(iii)(A)(1); or (ii) the maximum amount that may be taken into
account under a qualified plan pursuant to Section 401(a)(17) of the Code for the year in which the Separation Date occurs. With respect to reimbursements (whether such reimbursements are for business expenses or, to the extent permitted under
the Companys policies, other expenses) and/or in-kind benefits, in each case, that constitute deferred compensation subject to Section 409A of the Code, each of the following shall apply: (1) no reimbursement of expenses incurred by
the Executive during any taxable year shall be made after the last day of the following taxable year of the Executive, (2) the amount of expenses eligible for reimbursement, or in-kind benefits provided, during a taxable year of the Executive
shall not affect the expenses eligible for reimbursement, or in-kind benefits to be provided, to the Executive in any other taxable year, and (3) the right to reimbursement of such expenses or in-kind benefits shall not be subject to
liquidation or exchange for another benefit. The Company and Executive agree that this Agreement and the rights granted to the Executive hereunder are intended to meet the requirements of paragraphs (2), (3) and (4) of
Section 409A(a)(1)(A) of the Code. Notwithstanding anything to the contrary in this Agreement, no severance payments will become payable under this Agreement until Employee has a separation from service within the meaning of
Section 409A of the Code.

This Section 21 is intended to comply with the requirements of Section 409A of the
Code so that none of the severance payments and benefits to be provided hereunder will be subject to either (1) the six (6) month delay which may otherwise be required with respect to payments of deferred compensation to specified
employees as defined in Section 409A, and (b) any additional tax imposed under Section 409A, and any ambiguities herein will be interpreted to so comply. The Company and Executive 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 Executive under Section 409A.

22. Entire Agreement. This Agreement represents the entire agreement and understanding between the Company and Executive
concerning the subject matter of this Agreement and Executives employment with and separation from the Company and the events leading thereto and associated therewith, and supersedes and replaces any and all prior agreements and understandings
concerning the subject matter of this Agreement and Executives relationship with the Company, including (but not by way of limitation) the Severance Agreement, Retention Agreement, and Confidentiality Agreement, but with the exception of the
Stock Agreements and Section 4(b) of the Severance Agreement, all of which shall survive this Agreement.

23. No Oral
Modification. This Agreement may only be amended in a writing signed by Executive and the Companys then acting Chief Executive Officer or a specifically-authorized member of the Board.

24. Governing Law. This Agreement shall be governed by the laws of the State of Washington, without regard for choice-of-law
provisions. Executive consents to personal and exclusive jurisdiction and venue in the State of Washington.

25. Effective
Date.

a. Executive has seven (7) days after the date that he signs this Agreement to revoke it. This Agreement will
become effective on the eighth (8th) day after Executive signed this Agreement, so long as it has been signed by the Parties and has not been revoked by Executive before that date.

b. Executive has seven (7) days after the date that he signs the Release Agreement to

Effective Date).

APPENDIX B

RELEASE AGREEMENT

Executive agrees that the Severance Consideration represents settlement in full of all outstanding obligations owed to Executive by the Company and its current and former officers, directors, employees,
agents, investors, attorneys, shareholders, administrators, affiliates, benefit plans, plan administrators, insurers, trustees, divisions, and subsidiaries, and predecessor and successor corporations and assigns (collectively, the
Releasees). Executive, on his own behalf and on behalf of his respective heirs, family members, executors, agents, and assigns, hereby and forever releases the Releasees from, and agrees not to sue concerning, or in any manner to
institute, prosecute, or pursue, any claim, complaint, charge, duty, obligation, or cause of action relating to any matters of any kind, whether presently known or unknown, suspected or unsuspected, that Executive may possess against any of the
Releasees arising from any omissions, acts, facts, or damages that have occurred up until and including the date Executive signs this Agreement, including, without limitation:

a. any and all claims relating to or arising from Executives employment relationship with the Company and the termination of that relationship;

b. any and all claims relating to, or arising from, Executives right to purchase, or actual purchase of shares of stock 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 under any state or federal law;

c. any and all claims under the law of any jurisdiction including, but not limited to, wrongful discharge of employment; constructive
discharge from employment; termination in violation of public policy; discrimination; harassment; retaliation; breach of contract, both express and implied; breach of covenant of good faith and fair dealing, both express and implied; promissory
estoppel; negligent or intentional infliction of emotional distress; fraud; negligent or intentional misrepresentation; negligent or intentional interference with contract or prospective economic advantage; unfair business practices; defamation;
libel; slander; negligence; personal injury; assault; battery; invasion of privacy; false imprisonment; conversion; and disability benefits;

d. any and all claims for violation of any federal, state, or municipal statute, including, but not limited to, Title VII of the Civil Rights Act of 1964; the Civil Rights Act of 1991; the Rehabilitation
Act of 1973; the Americans with Disabilities Act of 1990; the Equal Pay Act; the Fair Labor Standards Act, except as prohibited by law; the Fair Credit Reporting Act; the Age Discrimination in Employment Act of 1967; the Older Workers Benefit

Employment and Reemployment Rights Act; Washington State Law Against Discrimination, as amended (Wash. Rev. Code §§ 49.60.010 et seq.); Washington Equal Pay Law, as amended (Wash. Rev. Code § 49.12.175); Washington sex discrimination
law (Wash. Rev. Code § 49.12.200); Washington age discrimination law (Wash. Rev. Code § 49.44.090); Washington whistleblower protection law (Wash. Rev. Code §§ 49.60.210, 49.12.005, and 49.12.130); Washington genetic testing

e. any and all claims for violation of the federal or any state constitution;

f. any and all claims arising out of any other laws and regulations relating to employment or employment discrimination;

g. any claim for any loss, cost, damage or expense arising out of any dispute over Company withholding the incorrect amount from any of
the proceeds received by Executive as a result of this Agreement; and

h. any and all claims for attorneys fees and
costs.

Executive agrees that the release set forth in this section shall be and remain in effect in all respects as a
complete general release as to the matters released. This release does not extend to any obligations incurred under this Agreement or to Executives vested rights in retirement or similar plans, programs or accounts. This release does not
release claims that cannot be released as a matter of law, including, but not limited to, Executives right to file a charge with or participate in a charge by the Equal Employment Opportunity Commission, or any other local, state, or federal
administrative body or government agency that is authorized to enforce or administer laws related to employment, against the Company (with the understanding that any such filing or participation does not give Executive the right to recover any
monetary damages against the Company; Executives release of claims herein bars Executive from recovering such monetary relief from the Company).

In addition, nothing in this release shall (i) operate to release or waive Executives rights, if any, under contract, law, as an employee, officer or director of the Company, to be defended and
indemnified by the Company against, any and all liability incurred with respect to any claim or proceeding to which Executive is or is threatened to be made a party because of Executives service as an employee, officer or director, or Chairman
of the Board of the Company, or (ii) operate to release or waive Executives rights, as an employee, officer or director of the Company, to be named, protected by and have coverage rights under the Companys insurance policies.

Acknowledgment of Waiver of Claims under ADEA. Executive understands and acknowledges that he is waiving and releasing
any rights he may have under the Age Discrimination in Employment Act of 1967 (ADEA), and that this waiver and release is knowing and voluntary. Executive understands and agrees that this waiver and release does not apply to any rights
or claims that may arise under the ADEA after the Effective Date of this Agreement. Executive understands and acknowledges that the consideration given for this waiver and release is in addition to anything of value to which Executive was already
entitled.

Executive further understands and acknowledges that he has been advised by this writing that: (a) he should
consult with an attorney prior to executing this Release Agreement; (b) he has twenty-one (21) days within which to consider and sign this Release Agreement; (c) he has seven (7) days following his execution of this
Release Agreement to revoke this Release Agreement; (d) this Release Agreement shall not be effective until after the revocation period has expired; and (e) nothing in this Release Agreement prevents or precludes Executive from challenging
or seeking a determination in good faith of the validity of this waiver under the ADEA, nor does it impose any condition precedent, penalties, or costs for doing so, unless specifically authorized by federal law. In the event Executive signs this
Release Agreement and returns it to the Company in less than the 21-day period identified above, Executive hereby acknowledges that he has freely and voluntarily chosen to waive the time period allotted for considering this Release Agreement.
Executive acknowledges and understands that revocation must be accomplished by a written notification to the Companys Corporate Secretary at 2601 Elliott Avenue, Seattle, Washington, 98121, that is received prior to the Effective Date. The
Parties agree that changes to this Agreement, whether material or immaterial, do not restart the running of the 21-day period.

Unknown Claims. Executive acknowledges that he has been advised to consult with legal
counsel and that he is familiar with the principle that a general release does not extend to claims that the releaser does not know or suspect to exist in his favor at the time of executing the release, which, if known by him, must have materially
affected his settlement with the released party. Executive being aware of said principle agrees to expressly waive any rights he may have to that effect, as well as under any other statute or common law principles of similar effect.

IN WITNESS WHEREOF, the Parties have executed this Release Agreement on the respective dates set forth below (which shall be no earlier
than the Separation Date)
