3.ELIGIBILITY FOR SEVERANCE BENEFITS (RELEASE REQUIRED)

Chief Financial Officer shall be entitled to receive the

date. If termination of Chief Financial Officers employment is made in anticipation of, connection with, or within two (2) years following a Change in Control, then Chief Financial Officer shall be entitled only to those

4.SEVERANCE BENEFITS (RELEASE REQUIRED)

A. SEVERANCE PAY

If the Chief Financial Officer meets all of the eligibility requirements of Section 3 above, the Chief Financial Officer shall receive his Severance Pay, in a lump sum provided the Chief Financial Officer
executes the Release described in Section 3C above within the minimum period required by Section 201 of the Older Workers Benefit Protection Act of 1990, as amended, to make such release effective. The lump sum will be paid within
fifteen (15) days after the Chief Financial Officers execution of an unrevoked release, (but not later than two and one-half (2 1/2) months after the end of the calendar year following the Chief Financial Officers termination of employment).

B. COMPANY PAID COBRA

The Company shall pay
for existing group employee benefit coverage continuation under the Consolidated Omnibus Budget Reconciliation Act of 1985 (COBRA) as provided by the Companys group agreements for twenty-four (24) months, beginning the
calendar month after Chief Executive Officers termination and provided at regular employee rates, or until Chief Executive Officer becomes eligible for group insurance benefits from another employer, whichever occurs first. If the full amount
of time allowable under COBRA as applied by the California Continuation Benefits Replacement Act, California Health and Safety Code § 1366.27 (Cal-COBRA) and the Companys group health plan is less than twenty-four
(24) months, then the Company shall pay for the cost of comparable coverage for the remainder of the 24-month period. Chief Executive Officer shall have an obligation to inform Company if he receives group coverage from another employer while
receiving COBRA or continued medical coverage from the Company. Chief Executive Officer may not increase the number of designated dependants, if any, during this time unless Chief Executive Officer does so at his own expense in accordance with the
applicable benefit Agreement. The period of such Company-paid COBRA coverage shall be considered part of Chief Executive Officers COBRA and Cal-COBRA coverage entitlement period, and may, for tax purposes, be considered income to the Chief
Executive Officer.

C. TAX LAW LIMITATIONS

Notwithstanding any other provision in this Agreement to the contrary, to the extent that any of the payments and benefits provided for in this Agreement or otherwise payable to the Chief Financial Officer are
presumed by a taxing authority to constitute parachute payments within the meaning of Section 280G of the Internal Revenue Code of 1986 as amended (Code), and the total payments provided for in this Agreement exceed the
amount triggering excise tax under the Code and but for this Section 4.C. would otherwise be presumed to be subject to the excise tax imposed by Section 4999 of the Code (the Excise Tax), the parties agree to cooperate with
each other under Paragraph 4.D. of the separate Change in Control Agreement executed by Chief Financial Officer on August 1, 2003.

5.WITHHOLDING TAXES ON BENEFITS

Notwithstanding any other provision of the Agreement, all severance benefits shall be reduced by any applicable federal, state, or local tax withholding requirements and as permitted by law.

6.NO OTHER SIMILAR BENEFITS

Except as provided for herein, the
severance benefits provided by the Agreement are in lieu of any other severance benefits provided by the Company under any other applicable agreement, practice or policy. This Severance Agreement expressly supercedes and makes inapplicable any other
severance agreement, practice, or policy related to severance benefits provided in the absence of a Change in Control. If there is a Change in Control as defined in Section 2.E above, the Change in Control Agreement executed by
Chief Financial Officer on August 1, 2003 alone shall govern Chief Financial Officers termination and severance benefits and this Agreement shall have no effect.

7.SET OFF/TERMINATION OF SEVERANCE BENEFITS

No payments or benefits payable to the Chief Financial Officer pursuant
to this Agreement shall be reduced by any amount the Chief Financial Officer may be entitled to receive as pension or retirement benefits, if any.

Subsequent employment by the Company, or any Company successor or affiliates prior to the payment of severance benefits will disqualify Chief Financial Officer from severance benefits.

8.DEATH

In the event Chief Financial Officer dies before the
severance monies are paid, payment shall be made to the designated beneficiary of the Chief Financial Officer in the same amount and at the same time that payment would have been made to the Chief Financial Officer.

9.LIMITATION ON TRANSFERABILITY

Except as provided in
Section 8 above, the interest of the Chief Financial Officer in the benefits described in this Agreement may not be sold, assigned, transferred or otherwise disposed of in any way, and any attempted sale, assignment, transfer or other
disposition shall be null and void. If Chief Financial Officer attempts to sell, assign, transfer or otherwise encumber his or her rights or interest in the Agreement, other than as permitted by Section 8, such act will be treated as an
election by the Chief Financial Officer to discontinue participation in the Agreement.

10.ARBITRATION

Chief Financial Officer and the Company agree that any dispute or claim, including all contract, tort, discrimination and other statutory claims, arising under or
relating to benefits under this Agreement or related to Chief Financial Officers employment or termination of employment (arbitrable claims) shall be resolved by arbitration. HOWEVER, Chief Financial Officer and the Company agree
that this arbitration provision shall not apply to any disputes or claims relating to or arising out of the misuse or misappropriation of trade secrets or proprietary

information. Arbitration shall be final and binding on the parties and shall be the exclusive remedy for arbitrable claims. Chief Financial Officer and the
Company hereby waive any rights each may have to a jury trial in regard to the arbitrable claims. Chief Financial Officer and the Company further agree that the arbitrator shall have the sole authority to determine arbitrability of any such
arbitrable claims. Arbitration shall be conducted by the American Arbitration Association in Orange County, California (or other mutually agreed upon city) under the National Rules for the Resolution of Employment Disputes. As, in any arbitration,
the burden of proof shall be allocated as provided by applicable law. The Company agrees to pay the fees and costs of the arbitrator. However, the arbitrator shall have the same authority as a court to award equitable relief, damages, costs, and
fees (excluding the costs and fees for the arbitrator) as provided by law for the particular claims asserted. This arbitration clause shall be governed by and construed in all respects under the terms of the Federal Arbitration Act
(FAA).

11.SETTLEMENT OF CLAIMS

The
Companys obligation to make the payments provided for in this Agreement and otherwise to perform its obligations hereunder shall not be affected by any circumstances, including, without limitation, any set-off, counterclaim, recoupment,
defense or other right which the Company may have against the Chief Financial Officer or others.

12.SEVERABILITY

If any term, provision, covenant or condition of this Agreement is held to be invalid, void, or unenforceable, the remainder of the provisions of this Agreement shall
remain in full force and effect and shall in no way be affected, impaired or invalidated thereby.

13.ENTIRE AGREEMENT; AMENDMENTS; WAIVER

This Agreement, together with all stock option agreements, restricted stock agreemetns and/or plans, any Employee Secrecy Agreements, and/or any
Proprietary Information and Inventions Agreements, is the entire agreement between the parties hereto concerning the subject matter hereof and supersedes and replaces all prior or contemporaneous agreements or understandings between the parties.
This Agreement may not be amended or modified in any manner, except by an instrument in writing signed by the Chief Financial Officer and an officer of the Company as designated by the Board. Except with respect to Good Reason in
Section 2.D, failure of either party to enforce any other provisions of this Agreement or any rights with respect thereto or failure to exercise any election provided for herein shall in no way be considered to be a waiver of such provisions,
rights or elections, or in any way effect the validity of this Agreement, except for the deemed consent and acquiesce provided for in Section 2.D. The failure of either party to exercise any of the provisions, rights or elections in this
Agreement, except for those described in Section 2.D, shall not preclude or prejudice such party from later enforcing or exercising those same provisions, rights or elections which it may have under this Agreement.

14.GOVERNING LAW

This Agreement shall be governed by and construed
in all respects in accordance with the laws of the State of California or the FAA, as applicable.

15.ATTORNEYS FEES

In the event of any action for the breach of this Agreement, the prevailing party shall be entitled to reasonable attorneys fees, costs and expenses incurred in connection with such action.

16.AT WILL EMPLOYMENT

Nothing herein is intended to alter the
at-will employment status of the Chief Financial Officer. Specifically, the Chief Financial Officers employment with the Company is at-will. Either the Company or the Chief Financial Officer may terminate his employment with or
without cause or good reason, and with or without notice. In addition, the Company has the right to change the Chief Financial Officers compensation, duties, assignments and responsibilities or location of employment at any time, with or
without cause or notice.

IN WITNESS WHEREOF, the parties have executed this Agreement as of the day and year first above written.
