2.



---

resignation, (2) allow the Company (or any successor, as applicable) at least 30 days from receipt of such written notice to cure such event, and (3) if such event is not reasonably
cured within such period, the Executives resignation from all positions he then holds with the Company and any successor entity is effective not later than 90 days after the expiration of the cure period.

benefit plan of the Company or any of its respective subsidiaries (in its capacity as such), (iii) an underwriter temporarily holding securities pursuant to an offering of such securities.

2. DUTIES; SCOPE OF EMPLOYMENT; COMPENSATION AND
BENEFITS.

(a) Position and Duties. The Company will employ the Executive to the position of Senior
Vice President, General Counsel. The Executive will devote substantially all of the Executives business efforts and time to the Company. The Executive agrees not to actively engage in any other employment, occupation or consulting activity for
any direct or indirect remuneration without the prior approval of the Chief Executive Officer, provided, however, that the Executive may engage in the following as long as such activities do not materially interfere with the Executives
duties and responsibilities with the Company: (i) serve on the board of one (1) unaffiliated corporation or the board of a trade association or charitable organization; (ii) engage in charitable activities and community affairs; or
(iii) manage the Executives personal investments and affairs; provided, however, that service on the board on an unaffiliated corporation, association or organization will be subject to the reasonable prior approval of the Chief
Executive Officer, which will not be unreasonably withheld or delayed.

(b) Annual Base Salary. The Executives
Annual Base Salary will be $250,000. This amount shall be reviewed annually in January of each year by the Board or Chief Executive Officer and, in the sole discretion of the Board or CEO, may be adjusted upward with such adjustments effective
January 1 of the respective year.

(c) Bonus. The Executives target bonus opportunity will be twenty
(20%) of the Executives Annual Base Salary, with a target range of 0-40%. The Executives actual bonus earned will be determined based on the Executives performance and achievement of corporate objectives and such other terms
as determined by the Board or the Chief Executive Officer, as applicable. For performance in 2010, the Executive will be eligible to earn the full amount of the bonus, payable in cash, as well as a performance-based stock option grant with a target
value of 6,700 shares and a performance-based restricted stock unit (RSU) award with a target value of 2,800 shares. The stock awards will be granted under the Companys Amended and Restated 2005 Equity Incentive Plan (the
Plan) and will be subject to the standard form of award agreement thereunder. In order to earn any bonus, the Executive must remain employed through the last day of the applicable performance period, and, with respect to the equity
grants, and to the extent otherwise required in the bonus plan document, through the actual payment date. Any earned bonus will be paid no later than March 15 of the year following the year of performance.

(d) Employee Benefits. The Executive and the Executives dependents, if
applicable, will be entitled to participate in all employee benefit plans, practices, policies and programs sponsored by the Company, on the same terms and conditions as generally applicable to employees of the Company, including but not limited to
medical, dental and vision insurance, paid time off, life insurance, and 401(k) retirement savings plan.

(e) Equity Plans. Subject to Board approval, the Company will grant the Executive an option (the
Option) to purchase 28,000 shares of the Companys common stock pursuant to the Plan at an exercise price equal to 100% of the fair market value of the Companys common stock on the date of grant. The Option will be subject to
a four-year vesting period subject to the Executives continued services with the Company, with twenty-five percent (25%) of the shares subject to the Option vesting on the one year anniversary of the vesting commencement date, and
one-forty-eighth (1/48th) of the shares subject to
the Option vesting for each month of continued service thereafter. The Option will be governed by the terms and conditions of the Plan and the Executives individual Option agreement. In the future, the Executive may be eligible for additional
equity awards granted pursuant to the Companys equity incentive plans, upon such terms as the Board may determine in its sole discretion.

3. TERMINATION. The Executives employment relationship with the Company is at-will. Accordingly, either the Executive and the
Company may terminate the employment relationship at any time, with or without cause, and with or without advance notice. However, if on or within 12 months following the closing of a Change in Control, (a) the Company or a successor
corporation terminates the Executives employment without Cause and other than as a result of death or disability, or (b) the Executive resigns for Good Reason, and provided such termination constitutes a separation from
service (as defined under Treasury Regulation Section 1.409A-1(h)) (a Separation from Service), then subject to the Executives obligations below, the Executive will be entitled to receive (collectively, the Change
in Control Severance Benefits):



| | (a) | a cash lump-sum payment in an amount equal to (i) 12 months of the Executives Annual Base Salary, if the termination occurs on or before the first
anniversary of the Effective Date, and (ii) 6 months of the Executives Annual Base Salary, if the termination occurs at any time thereafter, in either case at the rate of Annual Base Salary in effect on the effective date of the
termination, ignoring any decrease in Annual Base Salary that forms the basis for Good Reason (the Lump Sum Salary);
| | --- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (b) | if the Executive timely elects continued coverage under COBRA for himself and his covered dependents under the Companys group health plans
following such termination or resignation of employment, then the Company will pay the COBRA premiums necessary to continue the health insurance coverage in effect for the Executive and his eligible dependents on the termination date until the
earliest of (i) the close of (A) the 12 month period following the termination of employment if the termination occurs on or before the first anniversary of the Effective Date, and (B) the 6 month period following the termination date
if the termination occurs any time thereafter, (ii) the expiration of his eligibility for the continuation coverage under COBRA, or (ii) the date when he becomes eligible

| | for substantially equivalent health insurance coverage in connection with new employment or self-employment; and
| | ----------------------------------------------------------------------------------------------------------------



| | (c) | full acceleration of the vesting of all of the Executives then-outstanding compensatory stock grants as of the date of termination.
| | --- | ------------------------------------------------------------------------------------------------------------------------------------

Such Severance Benefits are conditional upon (a) the Executive continuing to comply with his obligations under his Proprietary
Information and Inventions Agreement following the termination date; and (b) the Executive delivering to the Company an effective, general release of claims in favor of the Company in a form acceptable to the Company within 60 days following
his termination date. The Lump Sum Salary will be paid on 60th day following the termination date.

4. SECTION 409A
COMPLIANCE. It is intended that all of the severance benefits and other payments payable under this Agreement satisfy, to the greatest extent possible, the exemptions from the application of Internal Revenue Code Section 409A
provided under Treasury Regulations 1.409A-1(b)(4), 1.409A-1(b)(5) and 1.409A-1(b)(9), and this Agreement will be construed to the greatest extent possible as consistent with those provisions. For purposes of Section 409A (including, without
limitation, for purposes of Treasury Regulation Section 1.409A-2(b)(2)(iii)), the Executives right to receive any installment payments under this Agreement (whether severance payments, reimbursements or otherwise) will be treated as a
right to receive a series of separate payments and, accordingly, each installment payment hereunder will at all times be considered a separate and distinct payment. Notwithstanding any provision to the contrary in this letter, if the Executive is
deemed by the Company at the time of the Separation from Service to be a specified employee for purposes of Section 409A(a)(2)(B)(i), and if any of the payments upon Separation from Service set forth herein and/or under any other
agreement with the Company are deemed to be deferred compensation, then to the extent delayed commencement of any portion of such payments is required in order to avoid a prohibited distribution under Section 409A(a)(2)(B)(i) and
the related adverse taxation under Section 409A, such payments will not be provided to the Executive prior to the earliest of (i) the expiration of the six-month period measured from the date of the Separation from Service with the
Company, (ii) the date of the Executives death or (iii) such earlier date as permitted under Section 409A without the imposition of adverse taxation. Upon the first business day following the expiration of such applicable
Section 409A(a)(2)(B)(i) period, all payments deferred pursuant to this paragraph will be paid in a lump sum to the Executive, and any remaining payments due will be paid as otherwise provided herein or in the applicable agreement.

5. PROPRIETARY INFORMATION AND INVENTIONS. The Executive agrees to
continue to be bound and abide by the terms of his Proprietary Information and Inventions Agreement. Executive acknowledges that nothing in this Agreement relieves the Executive of his obligations under that agreement.

6. MISCELLANEOUS.

(a) Arbitration. In the event of any dispute under the provisions of this Agreement, other than a dispute in which the primary relief sought is an equitable remedy such as an injunction, the
parties will be required to have the dispute, controversy or claim settled by



5.



---

arbitration in San Diego, California in accordance with the National Rules for the Resolution of Employment Disputes then in effect of the American Arbitration Association, before a panel of
three arbitrators, two of whom will be selected by the Company and the Executive, respectively, and the third of whom will be selected by the other two arbitrators. Any award entered by the arbitrators will be final, binding and nonappealable and
judgment may be entered thereon by either party in accordance with applicable law in any court of competent jurisdiction. This arbitration provision will be specifically enforceable. The arbitrators will have no authority to modify any provision of
this Agreement or to award a remedy for a dispute involving this Agreement other than a benefit specifically provided under or by virtue of the Agreement.

(b) Offsets. The severance benefits provided under this Agreement are intended to satisfy, to the greatest extent possible, any and all statutory obligations that may arise out of the
Executives termination of employment including, without limitation, the Worker Adjustment and Retraining Notification Act.

(c) Notices. For the purpose of this Agreement, notices and all other communications provided for in this Agreement will be in writing and will be deemed to have been duly given when
delivered or mailed by United States certified mail, return receipt requested, postage prepaid, addressed to the respective addresses set forth below, or to such other address as either party may have furnished to the other in writing in accordance
