(a)Pursuant to Section 8(a) of the Employment Agreement and this Separation Agreement, Executive’s receipt of severance is subject to Executive executing and not revoking this Separation Agreement. In consideration of Executive executing and not revoking this Separation Agreement, the Company agrees to pay (or provide, as applicable) Executive a lump sum cash payment of $1,000,000, comprised of 1.0 times Executive’s base salary plus 1.0 times Executive’s Target Amount as defined in Section 2(b) of the Employment Agreement, without proration, within five (5) business days of the Termination Date, and provide the other benefits in this Separation Agreement. Executive acknowledges that such consideration will be in full satisfaction of the payments and obligations provided under the Employment Agreement or otherwise from the Company (except for salary and customary benefits payable between the Effective Date and the Terminate Date), and he will not be entitled to any additional payments, salary, wages, bonuses, accrued vacation, housing allowances, relocation costs, interest, severance, stock, stock options, outplacement costs, fees, commissions or any other benefits and compensation, except as provided in any Company employee welfare or pension benefit plans as defined by the Executive Retirement Income Security Act of 1974, as amended (“ERISA”) (such plans, the “Benefit Plans”), this Separation Agreement, the Indemnification Agreement and/or the Equity Agreements.

(b)Stock. Executive acknowledges that as of the Termination Date, and after taking into account any accelerated vesting provided by the Employment Agreement or Equity Agreements, he will then hold vested and exercisable stock options to acquire shares of Company common stock and no more, and will hold vested restricted stock units settled for shares of Company common stock and no more as set forth in the Equity Report attached here to as Exhibit A, including the vesting of 35,000 restricted stock units granted under grant number 109218 and identified on such Exhibit A as unvested. All other equity awards will be automatically forfeited effective when Executive’s employment with the Company terminates. The exercise of any stock options and the settlement of any restricted stock units shall continue to be subject to the terms and conditions of the applicable Equity Agreement and the Employment Agreement, but after March 16, 2018 these equity grants, including the underlying shares, shall not be subject to any otherwise applicable stock ownership guidelines or stock retention requirements adopted by the Company’s Board of Directors or a committee thereof.

(c)Benefits. Executive’s health insurance benefits will cease on the last day of the month of the Termination Date, subject to Executive’s right to elect to continue his health insurance under the Consolidated Omnibus Budget Reconciliation Act of 1985 (“COBRA”) until the earliest of (i) twelve months after the Termination Date, or (ii) the date when Executive commences receiving substantially equivalent health insurance coverage in connection with new employment (with such premiums to be reimbursed by the Company as provided in the Employment Agreement). In addition, the Executive shall receive the following payments on the Termination Date: (i) all unpaid salary, and unpaid vacation accrued (if applicable), through the Termination Date, and (ii) any unreimbursed business expenses submitted within 30 days after the Termination Date and in accordance with the Company’s standard reimbursement policies and procedures. Subject to this Separation Agreement, the Employment Agreement, the Indemnification Agreement, the Equity Agreements and/or the Benefit Plans, Executive’s participation in all other benefits and incidents of employment (including, but not limited to, the accrual of vacation and paid time off, and the vesting of stock options and restricted stock units) will cease on the Termination Date.

(d)Directors and Officers Insurance. Executive will continue to be covered by the directors’ and officers’ liability policies paid for by the Company for his action on behalf of the Company through the Termination Date.

2.Confidential Information. Executive shall continue to comply with the terms and conditions of the Proprietary Rights Agreement, and maintain the confidentiality of all of the Company’s confidential and proprietary information; provided, however, that nothing in the Proprietary Rights Agreement or this Separation Agreement shall prevent Executive from disclosing such information if legally compelled to do so as part of the legal, judicial or administrative process; provided that the Executive gives the Company prior written notice of the compelled disclosure reasonably in advance of disclosure (unless prohibited from doing so by legal process) and cooperates and provides the Company an opportunity to seek confidentiality or other limitations on the disclosure. Executive also shall return to the Company all of the Company’s property, including all confidential and proprietary information, in Executive’s possession, on or before the Termination Date.

The Company agrees to fully and forever release Executive from any claim, duty, obligation or cause of action for monetary damages relating to any matters of any kind arising out of or relating to Executive’s employment by the Company or any agreement or arrangement with the Company, or Executive’s service as an officer of the Company and/or a director of the Company, whether presently known or unknown, suspected or unsuspected, other than (i) with respect to knowing violations of law, or receiving an improper personal benefit, fraud, theft or similar improper conduct, and (ii) claims for breaches of duties owed to the Company and its shareholders or for violations of securities rules and regulations. The Company represents that it is not aware of any claim against Executive other than the claims that are released by this Separation Agreement. For clarity, the foregoing release does not include claims pursuant to this Separation Agreement or enforcement of the Proprietary Rights Agreement and Section 8(c) of the Employment Agreement.

Executive agrees that the consideration set forth in this Separation Agreement represents settlement in full of all outstanding obligations owed to Executive by the Company. Executive, on his own behalf and on behalf of his respective heirs, family members, executors, agents, and assigns, hereby fully and forever releases the Company and its current and former: officers, directors, employees, agents, investors, attorneys, shareholders, administrators, affiliates, divisions, subsidiaries, predecessor and successor corporations and assigns (the “Releasees”) from, and agrees not to sue any of the Releasees concerning, any claim, duty, obligation or cause of action for monetary damages relating to any matters of any kind arising out of or relating to his employment by the Company or any agreement or arrangement with the Company, or his service as an officer of the Company and/or a director of the Company, whether presently known or unknown, suspected or unsuspected, that Executive may possess arising from any omissions, acts or facts that have occurred up until and including the Termination Date, excluding the “Excluded Claims” (as defined below) and including, without limitation:

(a)any and all claims relating to or arising from Executive’s employment with the Company, or the termination of that employment;

(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; breach of contract, both express and implied; breach of a covenant of good faith and fair dealing, both express and implied; promissory estoppel; negligent or intentional infliction of emotional distress; 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; and conversion;

4.Acknowledgement of Waiver of Claims Under ADEA. Executive acknowledges that he is waiving and releasing any rights he may have against the Releasees for monetary damages under the Age Discrimination in Employment Act of 1967 (“ADEA”) and that this waiver and release is knowing and voluntary. Executive and the Company agree that this waiver and release does not apply to any rights or claims that may arise under the ADEA after the Termination Date. Executive acknowledges that the consideration given for this waiver and release Agreement is in addition to anything of value to which Executive was already entitled. Executive further acknowledges that he has been advised by this writing that:

(a)he should consult with an attorney prior to executing this Separation Agreement;

(b)he has up to twenty-one (21) days within which to consider this Separation Agreement;

(c)he has seven (7) days following his execution of this Separation Agreement to revoke this Separation Agreement;

(d)this ADEA waiver shall not be effective until the revocation period has expired; and,

(e)nothing in this Separation 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.

5.Unknown Claims. The Parties represent that they are not aware of any claim by either of them other than the claims that are released by this Separation Agreement. Executive acknowledges that he has been advised by legal counsel and are familiar with the principle that a general release does not extend to claims which the releasor does not know or suspect to exist in his favor at the time of executing this Separation Agreement, which if known by him must have materially affected his settlement with the Releasee. Executive, being aware of said principle, agrees to expressly waive any rights Executive may have to that effect, as well as under any other statute or common law principles of similar effect.

6.Application for Employment. Executive understands and agrees that, as a condition of this Separation Agreement, he shall not be entitled to any employment with the Company, its subsidiaries, or any successor, and he hereby waives any alleged right of employment or re-employment with the Company, its subsidiaries or related companies, or any successor.

7.Company Interests. Executive will continue to act in the best interests of the Company prior to the Termination Date. Executive agrees both to immediately notify the Company upon receipt of any such subpoena or court order, and to furnish, within three (3) business days of its receipt, a copy of such subpoena or court order to the Company. If otherwise approached by anyone for counsel or assistance in the presentation or prosecution of any disputes, differences, grievances, claims, charges, or complaints against any of the Releasees, Executive shall state no more than that he cannot provide such counsel or assistance.

8.Costs. The Parties shall each bear their own costs, expert fees, attorney fees and other fees incurred in connection with the preparation of this Separation Agreement, except that the Company shall pay Executive’s attorney fees and costs incurred in connection with the preparation of this Separation Agreement (and any amendments thereto).

9.Arbitration. The Parties agree that any and all disputes arising out of, or relating to, the terms of this Separation Agreement, their interpretation, and any of the matters herein released, shall be subject to binding arbitration as described in Section 9(c) of the Employment Agreement.

10.No Representations. Each Party represents that it has had the opportunity to consult with an attorney, and has carefully read and understands the scope and effect of the provisions of this Separation Agreement. Neither Party has relied upon any representations or statements made by the other Party hereto which are not specifically set forth in this Separation Agreement.

11.No Oral Modification. Any modification or amendment of this Separation Agreement, or additional obligation assumed by either Party in connection with this Separation Agreement, shall be effective only if placed in writing and signed by both Parties or their authorized representatives.

12.Entire Agreement. This Separation Agreement, the Employment Agreement, the Indemnification Agreement, the Benefit Plans, the Proprietary Rights Agreement and the Equity Agreements represent the entire agreement and understanding between the Company and Executive concerning the subject matter of this Separation Agreement and Executive’s relationship with the Company, and supersede and replace any and all prior agreements and understandings between the Parties concerning the subject matter of this Separation Agreement and Executive’s relationship with the Company.

13.Governing Law. This Separation Agreement shall be governed by the laws of the State of Oregon, without regard for choice of law provisions.

14.Effective Date. This Separation Agreement is only effective after it has been signed by both parties and after eight (8) days have passed following the date Executive signed the Agreement without Executive revoking this Separation Agreement (the “Effective Date”).

15.Voluntary Execution of Release. This Separation Agreement is executed voluntarily and with the full intent of releasing all claims, and without any duress or undue influence by any of the Parties. The Parties acknowledge that:

(a)They have read this Separation Agreement;

(b)They have been represented in the preparation, negotiation, and execution of this Separation Agreement by legal counsel of their own choice or that they have voluntarily declined to seek such counsel;

(c)They understand the terms and consequences of this Separation Agreement and of the releases it contains; and

17. Non-solicitation and Non-competition. The receipt of any severance benefits will be subject to Executive agreeing that during his employment with the Company and for the 12 month period after the Termination Date (the “Continuance Period”), Executive will not (i) solicit any employee of the Company for employment other than at the Company, or (ii) directly or indirectly engage in (including as an officer, employee, consultant or advisor), have any ownership interest in or participate in or with any entity that as of the Termination Date, directly competes with the Company in any substantial business of the Company or any business reasonably expected to become a substantial business (i.e., at least 5% of the Company’s gross revenues) of the Company during the Continuance Period. Executive’s passive ownership of not more than 1% of any publicly traded company and/or 5% ownership of any privately held company will not constitute a breach of this Section 17. The Parties agree that Executive’s non-competition obligations pursuant to this Section 17 will apply to the companies set forth in Exhibit B attached hereto.

18. Non-disparagement. During his employment with the Company and the Continuance Period, Executive will not knowingly publicly disparage, criticize, or otherwise make any derogatory statements regarding the Company, its directors, or its officers. The Company’s then and future directors will not knowingly publicly disparage, criticize, or otherwise make any derogatory statements regarding Executive during his employment with the Company or the Continuance Period. The Company will also instruct its officers to not knowingly publicly disparage, criticize, or otherwise make any derogatory statements regarding Executive during his employment with the Company or the Continuance Period. Notwithstanding the foregoing, nothing contained in this Separation Agreement will be deemed to restrict Executive, the Company or any of the Company’s current or former officers and/or directors from communicating with any government agencies or otherwise participating in any investigation or proceeding that may be conducted by any government agency, including providing documents or other information, without notice to the Company if directed by the governmental agency.

IN WITNESS WHEREOF, each of the Parties has executed this Separation Agreement, in the case of the Company by a duly authorized officer, as of the day and year written below.
