ARTICLES III: PARTICIPATION AND VESTING

3.1 Eligibility and Participation.

(a) Eligibility. Eligibility to participate in the Plan is limited to those key employees of the Employer that are designated, from time to time, by the Board.

(b) Participation. An employee’s participation in the Plan shall be effective upon notification of such person by the Committee of eligibility to participate, completion of a Participation Agreement by such person, and acceptance of the Participation Agreement by the Committee. Except as modified by paragraph 3.2 below, participation in the Plan shall continue until such time as the Participant terminates employment with the Employer and as long thereafter as the Participant is eligible to receive benefits under this Plan.

3.2 Change in Employment Status. If the Board determines that a Participant’s employment performance is no longer at a level which deserves reward through participation in this Plan, but does not terminate the Participant’s employment with the Employer, participation herein and eligibility to receive benefits hereunder shall be limited to the Participant’s vested interest in such benefits as of the date designated by the Board. In such an event, the benefits payable to the Participant shall be based solely on the Participant’s Years of Credited Service and Compensation as of the date designated by the Board.

3.3 Vesting. A Participant whose employment with the Employer terminates because of Disability, Normal Retirement, Death or within 24 months after a Change in Control shall be 100% vested in the Participant’s Supplemental Retirement Benefit.

3.4 Suicide; Misrepresentation. Notwithstanding the provisions of Section 3.3 and Article IV and V, no benefit shall be paid to a Beneficiary if the Participant’s death occurs as a result of suicide during the 24 successive calendar months beginning with the calendar month

following the commencement of an individual’s participation in this Plan. Similarly, no benefit shall be paid if death occurs within the 24 successive calendar months following commencement of an individual’s participation in the Plan if the Participant has made a material misrepresentation in any form or document provided by the Participant to or for the benefit of the Employer.

3.5 Discharge for Cause. Notwithstanding the provisions of Section 3.3 and Articles IV and V, no benefit shall be paid hereunder if a Participant’s employment has been terminated for “cause.” A termination for cause is a termination by reason of the Board’s good faith determination that the Participant (i)acted dishonestly or engaged in willful misconduct in the performance of his duties for the Employer, (ii) breached a fiduciary duty to the Employer for personal profit to himself, (iii) intentionally failed to perform reasonably assigned duties, or (iv) willfully violated any law, rule or regulation (other than traffic violations or similar offenses) or any final cease and desist order. Notwithstanding the foregoing, in no event will the Participant be subject to termination for cause pursuant to clause (ii) or (iii) above until the Board shall have given written notice to the Participant specifically setting forth the claimed cause, and Participant shall have failed to cure, correct, or prevent the alleged default from continuing within 30 days after receipt of such written notice.

(a) Amount. The amount of the pre-termination survivor benefit shall be equal to the greater of the accrued Supplemental Retirement Benefit or 36 times the Participant’s Final Average Compensation.

(b) Payment. The pre-termination survivor benefit shall be paid to the Beneficiary in the form of 10 equal annual installments, without interest, with the first installment paid as soon as practicable after death and the remaining installments paid on the anniversary of the date of death.

4.2 Post-Termination Survivor Benefit.

(a) Death Prior to Commencement of Benefits. Subject to Section 3.4, if a Participant dies following his termination of employment with the Employer and prior to the commencement of benefits hereunder, the Employer shall pay a survivor benefit to the Participant’s Beneficiary as follows:

(i) Amount. The amount of the post-termination survivor benefit shall be equal to the Actuarial Equivalent value of the Participant’s Supplemental Retirement Benefit determined under Article V, calculated as of the date benefits were to have commenced had the Participant survived.

(ii) Payment. The post-termination survivor benefit shall be paid to the Beneficiary in the form of 10 equal annual installments, without interest, with

the first installment paid as soon as practicable after death and the remaining installments paid on the anniversary of the date of death.

(b) Death After Commencement of Benefits.

5.8 Payment to Guardian. If a Plan benefit is payable to a minor or a person declared incompetent or to a person incapable of handling the disposition of his property, the Committee may direct payment of such Plan benefit to the guardian, legal representative or such person having the care and custody of such minor, incompetent or person. The Committee may require proof of incompetency, minority, incapacity or guardianship as it may deem appropriate prior to distribution of the Plan benefit. Such distribution shall completely discharge the Committee and the Employer from all liability with respect to such benefit.

ARTICLE VI: BENEFICIARY DESIGNATION

6.1 Beneficiary Designation. Each Participant shall have the right, at any time, to designate any person or persons as his Beneficiary or Beneficiaries (both primary as well as secondary) to whom benefits under this Plan shall be paid in the event of his death prior to complete distribution to the Participant of the benefits due under the Plan. Each Beneficiary designation shall be in a written form prescribed by the Committee, and will be effective only when filed with the Committee during the Participant’s lifetime.

6.2 Amendments; Marital Status. Any Beneficiary designation may be changed by a Participant without the consent of any designated Beneficiary by the filing of a new Beneficiary designation with the Committee.

-10-

6.3 No Participant Designation. In the absence of an effective Beneficiary designation, or if all designated Beneficiaries predecease the Participant or die prior to complete distribution of the Participant’s benefits, then the Participant’s designated Beneficiary shall be deemed to be the Participant’s estate.

The Board may amend this Plan at any time or from time to time. Any amendment may provide different benefits or amounts of benefits from those herein set forth. However, no such termination, suspension or amendment shall adversely affect the benefits of Participants which have accrued prior to such action, the benefits of any Participant who has previously retired, or the benefits of any Beneficiary of a Participant who has previously died. Furthermore, no termination, suspension or amendment shall alter the applicability of the vesting schedule in Section 33 with respect to a Participant’s accrued benefit at the time of such termination, suspension or amendment.

ARTICLE X: MISCELLANEOUS

10.1 Unfunded Plan. This Plan is intended to be an unfunded plan maintained primarily to provide deferred compensation benefits for a select group of “management or highly compensation employees” within the meaning of Sections 201, 301, and 401 of the Employee Retirement Income Security act of 1974, as amended (“ERISA”), and therefore to be exempt from the provisions of Parts 2, 3, and 4 of Title I of ERISA. Accordingly, the Plan shall terminate and no further benefits shall be paid hereunder in the event it is determined by a court of competent jurisdiction or by an opinion of counsel that the Plan constitutes an employee pension benefit plan within the meaning of Section 3(2) of ERISA which is not so exempt.

10.2 Unsecured General Creditor. Participants and their Beneficiaries, heirs, successors, and assigns shall have no legal or equitable rights, interest or claims in any property or assets of the Employer, nor shall they be Beneficiaries of, or have any rights, claims or interests in any life insurance policies, annuity contracts, or the proceeds therefrom owned or which may be acquired by the Employer. Except as may be provided in Section 10.3, such policies, annuity contracts or other assets of the Employer shall not be held under any trust for the benefit of Participants, their Beneficiaries, heirs, successors or assigns, or held in any way as

-12-

collateral security for the fulfilling of the obligations of the Employer under this Plan. Any and all of the Employer’s assets and policies shall be, and remain, the general, unpledged, unrestricted assets of the Employer. The Employer’s obligation under the Plan shall be that of an unfunded and unsecured promise to pay money in the future.

10.3 Trust Fund. The Employer shall be responsible for the payment of all benefits provided under the Plan. At its discretion, the Employer may establish one or more trusts, with such trustees as the Board may approve, for the purpose of providing for the payment of such benefits. Such trust or trusts may be irrevocable, but the assets thereof shall be subject to the claims of the Employer’s creditors. To the extent any benefits provided under the Plan are actually paid from any such trust, the Employer shall have no further obligation with respect thereto, but to the extent not so paid, such benefits shall remain the obligation of, and shall be paid by, the Employer.

10.4 Nonassignability. Neither a Participant nor any other person shall have any right to commute, sell, assign, transfer, pledge, anticipate, mortgage or otherwise encumber, transfer, hypothecate or convey in advance of actual receipt the amounts, if any, payable hereunder, or any part thereof, which are, and all rights to which are, expressly declared to be unassignable and nontransferable. No part of the amount payable shall, prior to actual payment, be subject to seizure or sequestration for the payment of any debts, judgments, alimony or separate maintenance owed by a Participant or any other person, nor be transferable by operation of law in the event of a Participant’s or any other person’s bankruptcy or insolvency.

10.5 Not a Contract of Employment. The terms and conditions of this Plan shall not be deemed to constitute a contract of employment between the Employer and the Participant, and the Participant (or his Beneficiary) shall have no rights against the Employer except as may otherwise be specifically provided herein. Moreover, nothing in this Plan shall be deemed to give a Participant the right to be retained in the service of the Employer or to interfere with the right of the Employer to discipline or discharge him at any time.

10.6 Protective Provisions. A Participant will cooperate with the Employer by furnishing any and all information requested by the Employer, in order to facilitate the payment of benefit hereunder, and by taking such physical examinations as the Employer may deem necessary and taking such other action as may be requested by the Employer.

10.7 Terms. Whenever any words are used herein in the masculine, they shall be construed as though they were used in the feminine in all cases where they would so apply; and wherever any words are used herein in the singular or in the plural, they shall be construed as though they were used in the plural or singular, as the case may be, in all cases where they would so apply.

10.8 Captions. The captions of the articles, sections, and paragraphs of this Plan are for convenience only and shall not control or affect the meaning or construction of any of its provisions.

-13-

10.9 Governing Law. The provisions of this Plan shall be construed, interpreted, and governed in all respects in accordance with applicable federal law and, to the extent not preempted by such federal law, in accordance with the laws of the State of California.

10.10 Validity. If any provision of this Plan shall be held illegal or invalid for any reason, the remaining provisions shall nevertheless continue in full force and effect without being impaired or invalidated in any way.

10.11 Notice. Any notice or filing required or permitted to be given to the Committee under the Plan shall be sufficient in writing and hand delivered, or sent by registered or certified mail, to any member of the Committee, or to the Employer’s statutory agent. Such notice shall be deemed given as of the date of delivery or, if delivery is made by mail, as of the date shown on the postmark on the receipt for registration or certification.

10.12 Successors. The provisions of this Plan shall bind and inure to the benefit of the Employer and its successors and assigns. The term successors as used herein shall include any corporate or other business entity which shall, whether by merger, consolidation, purchase or otherwise acquire all or substantially all of the business and assets of the Employer, and successors of any such corporation or other business entity.
