hereunder to the best of his abilities in a diligent, trustworthy, businesslike and efficient manner. 
 3. Board Membership.

 (a) Base Salary. For all services to be rendered by Executive pursuant to this Agreement, the Company shall pay Executive
Four Hundred Thousand Dollars ($400,000) per annum or such higher rate as the Board may determine from time to time (as adjusted from time to time, the “Base Salary”), which salary shall be payable by the Company in regular
installments in accordance with the Company’s general payroll practices. The Base Salary will be evaluated at least annually by the Company’s Compensation Committee commencing at the 2008 meeting to evaluate compensation of the

Board and its Compensation Committee. A summary of the Company’s benefits is attached to this Agreement as Exhibit B. Other than as specified in paragraph (f) of this section, nothing contained in this Agreement shall be construed

 5. Term. 
 (a)
At-Will Employment. Executive’s employment with the Company shall be “at-will” employment under the laws of California, which means employment may be terminated by either the Company or Executive at any time and for any
reason or for no reason, with or without notice. Without limiting the effect of the foregoing, the Employment Period shall continue until terminated: 
 (i) by Executive’s resignation (with or without Good Reason (as defined below)); 
  

 2 








 (ii) by Executive’s death or his mental or physical disability or incapacity (each
as determined by the Board in its good faith judgment); or 
 (iii) by the Company at any time (with or without Cause (as
defined below)). 
 (b) Termination of Employment. If the Employment Period is terminated by the Company without
Cause or by Executive with Good Reason, Executive shall be entitled to continue to receive (i) his Base Salary payable in regular installments as special severance payments from the date of termination and (ii) medical and dental benefits
on the same terms as such benefits were provided as of immediately before such termination, in each case through the one (1) year anniversary of the date of termination. Notwithstanding anything herein to the contrary, no amounts shall be
payable pursuant to this Section 5(b) unless and until Executive has executed and delivered to the Company a general release in favor of the Company in form and substance reasonably satisfactory to the Board and only so long as Executive
has not breached the provisions of Sections 7, 8 and 9 hereof. Except as provided in this Section 5(b), Executive shall not be entitled to any other salary, compensation or benefits after termination of the Employment Period.
Notwithstanding the foregoing, if Executive is a “specified employee” of the Company (as defined in Treasury Regulation Section 1.409A-1(i)), any severance payments that would otherwise be paid within six months after the last day of
the Employment Period that exceed the lesser of (x) two times the compensation limit under Section 401(a)(17) of the Internal Revenue Code of 1986, as amended, for the calendar year of the last day of the Employment Period, and
(y) two times Executive’s annual compensation for the calendar year prior to the calendar year of the last day of termination shall instead be paid on the six month anniversary of the last day of the Employment Period. 
 (c) If the Employment Period is terminated by the Company for Cause, by Executive’s resignation without Good Reason, or due to
Executive’s death or his mental or physical disability for a period of ninety (90) consecutive days in which Executive is incapable, after reasonable accommodation, of performing Executive’s duties, Executive shall only be entitled to
receive his Base Salary through the date of termination or expiration and shall not be entitled to any other salary, compensation or benefits from the Company or its subsidiaries thereafter. 
 (d) Except as otherwise expressly provided herein, all of Executive’s rights to salary, bonuses, fringe benefits and other
compensation hereunder which accrue or become payable after the termination or expiration of the Employment Period shall cease upon such termination or expiration, other than those expressly required under applicable law (such as COBRA). The Company
may offset any amounts Executive owes it or its subsidiaries against any amounts it or its subsidiaries owes Executive hereunder.

corporation, limited liability corporation, partnership, joint venture, trust or other enterprise, including service with respect to employee benefit plans, whether or not the basis of such Proceeding is Executive’s alleged action in an

 7. Confidential Information. Executive acknowledges that the information, observations and data (including trade secrets) obtained by him while employed by the Company and its subsidiaries concerning the
business or affairs of the Company or any of its subsidiaries (“Confidential Information”) are the property of the Company or such subsidiary. Therefore, Executive agrees that he shall not disclose to any unauthorized person or use
for his own purposes any Confidential Information without the prior written consent of the Board, unless and to the extent that the Confidential Information becomes generally known to and available for use by the public other than as a result of
Executive’s acts or omissions. Executive shall deliver to the Company at the termination or expiration of the Employment Period, or at any other time the Company may request, all memoranda, notes, plans, records, reports, computer tapes,

have under his control.

 10. Enforcement. If, at the time of enforcement of Sections 7, 8 and 9 of this
Agreement, a court holds that the restrictions stated herein are unreasonable under circumstances then existing, the parties hereto agree that the maximum period or scope under such circumstances shall be substituted for the stated period or scope.
Because Executive’s services are unique and because Executive has access to Confidential Information and Work Product, the parties hereto agree that money damages would not be an adequate remedy for any breach of this Agreement. Therefore, in
the event a breach or threatened breach of this Agreement, the Company or its successors or assigns, in addition to other rights and remedies existing in their favor, shall be entitled to specific performance and/or injunctive or other equitable
relief from a court of competent jurisdiction in order to enforce, or prevent any violations of, the provisions hereof (without posting a bond or other security). In addition, in the event of a breach or violation by Executive of
Section 9, the nonsolicitation period shall be tolled until such breach or violation has been duly cured. Executive acknowledges that the restrictions contained in Section 9 are reasonable and that he has reviewed the
provisions of this Agreement with his legal counsel. 
 11. Executive’s Representations. Executive hereby represents and
warrants to the Company that (i) the execution, delivery and performance of this Agreement by Executive do not and shall not conflict with, breach, violate or cause a default under any contract, agreement, instrument, order, judgment or decree
to which Executive is a party or by which he is bound, (ii) Executive is not a party to or bound by any employment agreement or noncompete agreement with any other person or entity, and (iii) upon the execution and delivery of this
Agreement by the Company, this Agreement shall be the valid and binding obligation of Executive, enforceable in accordance with its terms. Executive hereby acknowledges and represents that he has consulted with independent legal counsel regarding
his rights and obligations under this Agreement and that he fully understands the terms and conditions contained herein. 
 12.
Survival. Sections 6 through 21 shall survive and continue in full force in accordance with their terms notwithstanding the expiration or termination of the Employment Period.
