                  time, to designate his or her Beneficiary (both primary as

                  completing and signing the Beneficiary Designation Form, and

                  previously filed shall be cancelled. The Committee shall be
                  entitled to rely on the last Beneficiary Designation Form
                  filed by the Participant and accepted by the Committee before
                  his or her death.

5.3               Acknowledgment. No designation or change in designation of a
                  Beneficiary shall be effective until received, accepted and

                  agent.

                  designate a Beneficiary as provided in Sections 5.1, 5.2 and

                  Participant or die prior to complete distribution of the
                  Participant's benefits, then the Participant's designated
                  Beneficiary shall be deemed to be his or her surviving spouse.
                  If the Participant has no surviving spouse, the benefits
                  remaining under the Plan to be paid to a Beneficiary shall be

                  Participant's estate.

5.5               Doubt as to Beneficiary. If the Committee has any doubt as to
                  the proper Beneficiary to receive payments pursuant to this
                  Plan, the Committee shall have the right, exercisable in its
                  discretion, before a Change in Control, to cause the Trustee

                  Committee's satisfaction.

5.6               Discharge of Obligations. The payment of benefits under the
                  Plan to a Beneficiary shall fully and completely discharge all
                  Employers and the Committee from all further obligations under
                  this Plan with respect to the Participant, and the
                  Participant's Plan Agreement shall terminate upon such full
                  payment of benefits.

                  Before Change in Control. Prior to one year before a Change in

                  or modify the Plan or any related Plan Agreement, in whole or
                  in part, with respect to Participants whose services are
                  retained by the Employer. Notwithstanding the foregoing, no
                  termination, amendment or modification shall be effective to
                  decrease or reduce a Participant's potential benefits under
                  this Plan below the balance in his or her Participant's
                  Account as of the effective date of the termination, amendment
                  or modification.

                  corporation, trust or other person that succeeds to all or any
                  substantial portion of the assets of the Company shall have
                  the right to terminate, amend or modify the Plan and/or any
                  Plan Agreement in effect prior to such Change in Control, and
                  all benefits under the Plan and any such Plan Agreement shall
                  thereafter be paid in accordance with the terms of the Plan
                  and such Plan Agreement, as in effect immediately prior to
                  such Change in Control. If the Plan is terminated, amended, or
                  modified within one year before the Change in Control, such
                  termination, amendment or modification shall be considered
                  void as of the date of the termination, amendment or
                  modification. Any provision of this Plan or any Plan Agreement
                  to the contrary shall be construed in accordance with this

                  Agreement of any Participant shall terminate upon the full
                  payment of the applicable benefit provided under Article 4.

                  Trustee, Participant and a Participant's Beneficiary as to the
                  assets of the Trust. The Employers shall at all times remain

                                    administrative expenses of the Trust to

                                    expenses, including all taxes, of the Trust

                           above shall qualify for and be treated as separate

                                    such material or information is necessary;
                                    and

                  review promptly, and not later than 60 days after the filing

                  provisions of this Article 11 is a mandatory prerequisite to a

                  any claim for benefits under this Plan.

                                   ARTICLE 12
                                  MISCELLANEOUS

12.1              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 an Employer. Any and all of an Employer's assets
                  shall be, and remain, the general, unpledged and unrestricted
                  assets of the Employer. An Employer's obligation under the
                  Plan shall be merely that of an unfunded and unsecured promise
                  to pay money in the future.

12.2              Employer's Liability. An Employer's liability for the payment
                  of benefits shall be defined only by the Plan and the Plan
                  Agreement, as entered into between the Employer and a
                  Participant. An Employer shall have no obligation to a
                  Participant under the Plan except as expressly provided in the
                  Plan and his or her Plan Agreement.

12.3              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 non-transferable, except that the foregoing
                  shall not apply to any family support obligations set forth in
                  a court order. No part of the amounts payable shall, prior to
                  actual payment, be subject to seizure or sequestration for the

                  be transferable by operation of law in the event of a
                  Participant's or any other person's bankruptcy or insolvency.

12.4              Not a Contract of Employment. The terms and condition of this
                  Plan shall not be deemed to constitute a contract of
                  employment between any Employer and the Participant. Such
                  employment is hereby acknowledged to be an "at will"
                  employment relationship that can be terminated at any time for
                  any reason, with or without cause, unless expressly provided
                  in a written employment agreement. Nothing in this Plan shall
                  be deemed to give a Participant the right to be employed in
                  the service of any Employer, or to interfere with the right of
                  any Employer to discipline or discharge the Participant at any
                  time.

12.5              Furnishing Information. A Participant will cooperate with the
                  Committee by furnishing any and all information requested by
                  the Committee and take such other actions as may be requested
                  in order to facilitate the administration of the Plan and the
                  payments of benefits hereunder, including but not limited to
                  taking such physical examinations as the Committee may deem
                  necessary.

12.6              Terms. Whenever 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 the singular, as the case may be, in all
                  cases where they would so apply.

12.7              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.

12.8              Governing Law. The provisions of this Plan shall be construed
                  and interpreted according to the laws of the State of
                  California.

12.9              Validity. In case any provision of this Plan shall be illegal
                  or invalid for any reason, said illegality or invalidity shall
                  not affect the remaining parts hereof, but this Plan shall be
                  construed and enforced as if such illegal and invalid
                  provision had never been inserted herein.

12.10             Notice. Any notice or filing required or permitted to be given
                  to the Committee under this Plan shall be sufficient if in
                  writing and hand-delivered, or sent by registered or certified
                  mail, to the address below:

                  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.

                  Any notice or filing required or permitted to be given to a
                  Participant under this Plan shall be sufficient if in writing
                  and hand-delivered, or sent by mail, to the last known address
                  of the Participant.

12.11             Successors. The provisions of this Plan shall bind and inure
                  to the benefit of the Participant's Employer and its
                  successors and assigns and the Participant, the Participant's
                  Beneficiaries, and their permitted successors and assigns.

12.12             Spouse's Interest. The interest in the benefits hereunder of a
                  spouse of a Participant who has predeceased the Participant
                  shall automatically pass to the Participant and shall not be
                  transferable by such spouse in any manner, including but not
                  limited to such spouse's will, nor shall such interest pass
                  under the laws of intestate succession.

12.13             Incompetent. If the Committee determines in its discretion
                  that a benefit under this Plan is to be paid to a minor, a
                  person declared incompetent or to a person incapable of
                  handling the disposition of that person's property, the
                  Committee may direct payment of such benefit to the guardian,
                  legal representative or person having the care and custody of
                  such minor, incompetent or incapable person. The Committee may
                  require proof of minority, incompetency, incapacity or
                  guardianship, as it may deem appropriate prior to distribution
                  of the benefit. Any payment of a benefit shall be a payment
                  for the account of the Participant and the Participant's
                  Beneficiary, as the case may be, and shall be a complete
                  discharge of any liability under the Plan for such payment
                  amount.

12.14             Distribution in the Event of Taxation. If, for any reason, all
                  or any portion of a Participant's benefit under this Plan
                  becomes taxable to the Participant prior to the Vesting Date,
                  a Participant may petition the Committee, if prior to a Change
                  in Control, or the Trustee, after a Change in Control, for a
                  distribution of assets sufficient to meet the Participant's
                  tax liability (including additions to tax, penalties and
                  interest). Upon the grant of such a petition, which grant
                  shall not be unreasonably withheld, the Trustee shall
                  distribute to the Participant from the Trust immediately
                  available funds in an amount equal to that Participant's
                  federal, state and local tax liability associated with such
                  taxation, which liability shall be

                  measured by using that Participant's then current highest
                  federal, state and local marginal tax rate, plus the rates or
                  amounts for the applicable additions to tax, penalties and
                  interest. If the petition is granted, the tax liability
                  distribution shall be made within 90 days of the date when the
                  Participant's petition is granted.
