RECITALS

A. Employee is an at-will employee of Company, working pursuant to an employment agreement dated February 27, 2013 and a November 12, 2014 amendment thereto;

B. Employee will separate from Company effective June 3, 2015 (the “Separation Date”); and

C. The Parties want to resolve any and all actual or potential disputes arising out of or relating to Employee’s employment with Company or the cessation of that employment.

Company and Employee hereby agree as follows:

1. Severance Benefit. In consideration of the covenants and releases in this Agreement, Company will: (a) pay Employee a severance benefit of six months of Employee’s annual base salary effective as of the Separation Date (reflecting Employee’s annual base salary as recently increased to reflect a five business day work week), less withholdings authorized or required by law, in accordance with Company’s normal payroll cycle, commencing on the first payroll cycle after the Effective Date of this Agreement; and (b) reimburse Employee for six months, starting the month immediately after the Effective Date, for Employee’s monthly COBRA premiums, subject to applicable laws and requirements and Employee’s eligibility and compliance with COBRA and insurance requirements. After the six-month period referenced herein, Company will no longer pay or reimburse Employee for any COBRA or other health insurance premiums. However, if Employee obtains other health insurance coverage from another employer, company, or business entity within the six months after the Effective Date, Company will no longer be required to pay for or reimburse Employee for COBRA. Employee is required to inform Company immediately after Employee learns she will be covered by other health insurance and when that coverage begins. Together, Sections 1(a)-(b) hereof are the “Severance Benefit”. Employee must comply with all of the terms of this Agreement, and her Employee Proprietary Information and Assignment of Inventions Agreement (“Confidentiality Agreement”) in order to receive, or continue to receive, the Severance Benefit. Employee acknowledges and agrees that but for her agreement to enter into, and provide the releases in, this Agreement, she is not entitled to the Severance Benefit. Employee further acknowledges and agrees that the Severance Benefit does not constitute, in any way, any sort of severance plan.

2. Wages and Vacation Time Paid. Employee acknowledges that Company paid Employee on Separation Date all of Employee’s wages due and owing and paid for all accrued-but-unused paid time off. Employee acknowledges that she has received all wages or

Page 1 of 6

compensation that Company owes her. Additionally, Employee acknowledges that Company has reimbursed her for all Company business expenses she has incurred up through the Separation Date. Employee’s receipt of these wages, accrued benefits, and reimbursements was not conditioned upon the execution of this Agreement.

Health Benefits. Company provided Employee with health insurance during her employment with Company. If Employee wants to continue her health insurance coverage, she acknowledges she must do so through COBRA. Except as set forth above in Section 1. Company will not be paying for or reimbursing Employee for any health insurance costs or premiums (COBRA) after her separation from Company.

4. Equity. Employee is vested in options to purchase (i) 45,000 shares of Common Stock granted pursuant to the Company’s 2005 Stock Plan and (ii) 37,500 shares of Common Stock granted pursuant to the Company’s 2015 Equity Incentive Plan. Such Options may be exercised for three (3) months from the date hereof, pursuant to the provisions of the respective plan under which they were granted.

5. Reference Requests. If contacted by prospective employers, Company will release information concerning only the dates of Employee’s employment and the last position held. Company will inform prospective employers that it is Company policy to release only this information.

6. Release and Waiver by Employee: Employee, on behalf of herself and her heirs, executors, administrators, assigns and successors, fully and forever releases and discharges Company, and, as applicable, its current, former and future subsidiaries and related entities, successors, officers, directors, shareholders, agents, employees and assigns (collectively “Releasees”), from any and all claims, liabilities and causes of action, of every nature, kind and description, in law, equity or otherwise, which have arisen, occurred or existed at any time prior to her signing of this Agreement, including, without limitation, any and all claims, liabilities and causes of action arising out of or relating to Employee’s employment with Company or the cessation of that employment.

7. Waiver of Employment-Related Claims. Employee waives and releases, except the potential claims identified below, all rights, remedies, or claims she may have had or now has against Company or any of the Releasees regarding employment-related causes of action, that are applicable to Employee and Company and to which Company is subject, including without limitation, claims of wrongful discharge, breach of contract, retaliation, breach of the covenant of good faith and fair dealing, fraud, violation of public policy, claims that she is or was a “whistleblower,” defamation, discrimination, personal injury, physical injury, emotional distress, claims under Title VII of the Civil Rights Act of 1964, the Americans With Disabilities Act, Age Discrimination in Employment Act of 1967, the Older Workers Benefit Protection Act of 1990, the Federal Rehabilitation Act, the California Fair Employment and Housing Act, the California Family Rights Act, the Equal Pay Act of 1963, the provisions of the California Labor Code and any other federal, state or local laws and regulations relating to employment, conditions of employment (including wage and hour laws) and/or employment discrimination. Claims not covered by the Employee’s waiver and release are: (a) claims for unemployment insurance benefits, (b) claims under California’s Workers Compensation laws, (c) claims relating to the

Page 2 of 6

Company’s express obligations under this Agreement, (d) claims that cannot be waived or released as a matter of law (including, without limitation, administrative claims before the United States Equal Employment Opportunity Commission (“EEOC”), including Employee testifying, assisting or participating in an investigation or proceeding by the EEOC or any comparable state or local agency), and (e) claims under that certain Indemnification Agreement with the Company dated as of June 24, 2014. Employee represents and warrants that she does not believe she currently has any work related injuries. Employee’s waiver and release, however, are intended to be a complete bar to any recovery or personal benefit by or to Employee regarding any claim (except those which cannot be released under law), including those raised through a charge with the EEOC. Accordingly, nothing in this section will be deemed to limit Company’s right to seek immediate dismissal of the charge or complaint on the basis that Employee’s signing of this Agreement constitutes a full release of any individual rights under the federal discrimination laws, or to seek restitution to the extent permitted by law of the economic benefits provided to Employee under this Agreement in the event Employee successfully challenges the validity of this release and prevails in any claim under the federal discrimination laws.

8. Waiver of Unknown Claims. In executing this Agreement, Employee waives and relinquishes all rights and benefits granted to Employee under the provisions of Section 1542 of the California Civil Code or any similar statute or doctrine. Civil Code section 1542 provides as follows:

A general release does not extend to claims which the creditor does not know or suspect to exist in his or her favor at the time of executing the release, which if known by him or her must have materially affected his or her settlement with the debtor.

Employee acknowledges that she has read all of this Agreement, including the above Civil Code section, and that both the general release and Employee’s release of all rights and benefits pursuant to Civil Code section 1542 are fully understood. In waiving the provisions of Section 1542 of the California Civil Code, Employee acknowledges that she may later discover facts in addition to or different from those which she now believes to be true with respect to the matters released in this Agreement. But, she agrees that she has taken that possibility into account in reaching this Agreement, and that the releases in this Agreement will remain in effect as full and complete releases notwithstanding the discovery or existence of additional or different facts.

9. Severability. If a Court rules that any provision in this Agreement is unenforceable, it will not affect the enforceability of the remaining provisions. The Court may enforce all remaining provisions to the extent permitted by law.

10. Confidentiality of Agreement. The Parties will not disclose to others, and will keep confidential, unless compelled by legal process or other legal requirements, including without limitation the Company’s compliance with its obligations under the U.S. securities laws, both the fact of and terms of this Agreement. The Parties may disclose this information to attorneys, accountants and other professional advisors to whom the disclosure is necessary to accomplish the purposes for which these professional advisors were retained. Employee may

disclose the terms of this Agreement to her family members if they agree in advance to keep this Agreement and its terms confidential. The Parties may disclose the terms of this Agreement as necessary to enforce its terms or to remedy for the breach of its terms. Employee acknowledges that keeping confidential the fact and terms of this Agreement is a material provision of this Agreement, and the breach of this provision will relieve Company of its obligation to pay or continue to pay the Severance Benefit and will allow Company to seek recovery of any amounts paid to Employee under this Agreement, subject to applicable laws.

11. Confidential Information. Employee acknowledges that, as a condition to her employment with Company, she executed the Confidentiality Agreement. This Agreement in no way affects, alters, or waives Employee’s obligations or Company’s rights under the Confidentiality Agreement (together with its attached exhibits).

Employee agrees not to disparage, in any manner, Company, its parents, successors, sister companies, divisions or affiliates; provided, however, that Employee may respond accurately and fully to any question, inquiry or request for information when required by legal process.

Company. Employee’s full cooperation will include, but not be limited to, meeting with representatives of Company and/or meeting with Company counsel (and providing truthful responses to any questions by Company or its counsel), cooperating in discovery, providing affidavits and testimony as may be required or deemed necessary by Company, and informing Company of any requests by any third party for Employee’s testimony or information or documents in Employee’s possession.

14. Return of Company Property. In order to receive the Severance Benefit, Employee must return all Company property in Employee’s possession, custody or control no later than five business days after the Separation Date.
