      (d) Liability of Committee Members.

          No member of the Board or the Committee will be liable for any action
or determination made in good faith by the Board or the Committee with respect
to the Plan.

      (e) Administration of the Plan Following a Change in Control.

          Within 30 days after the occurrence of a Change in Control, the
Committee shall appoint an independent organization which shall thereafter
administer the Plan and have all of the powers and duties formerly held and
exercised by the Committee pursuant to Section 3(c) with respect to the Plan.
Upon such appointment, the Committee shall cease to have any responsibility with
respect to the administration of the Plan.

      4. PARTICIPATION.

      Each Eligible Employee who elects to defer base salary under the Plan in
accordance with the Rules or who makes a deferral election available under the
terms of the Management Incentive Plan or the Long-Term Incentive Plan, shall
automatically become a Participant in the Plan.

      5. DEFERRED COMPENSATION.

          The Committee shall promulgate Rules governing (i) elections by
Eligible Employees to defer base salary and (ii) the establishment of Accounts
to which shall be credited amounts deferred by an Eligible Employee pursuant to
an election described in (i) or any deferral election made available under the

designation of investments to be used to measure the value of such Accounts, the
crediting of interest or earnings to such Accounts, and the time, form and value
of distributions from such Accounts.

      6. AMENDMENT OR TERMINATION OF THE PLAN.

          Except as otherwise provided in this Section 6, the Board may amend,
suspend or terminate the Plan at any time. In the event of such termination, the
Accounts of Participants shall be paid at such times and in such forms as shall
be determined pursuant to the Rules, unless the Board prescribes a different
time or times for payment of such Accounts. No amendment, suspension or
termination (other than an amendment to discontinue future salary deferrals)
approved by the Board after six months prior to the public announcement of a
proposed transaction which, when effected, is a Change in Control or before the
date which is two years

                                       3
<PAGE>
after the date of a Change in Control (the `Benefit Protection Period') shall be
valid or effective if such amendment, suspension or termination would alter the
terms of these resolutions or adversely affect the amount of a Participant's
Account under the Plan, whether or not the Participant's employment had
terminated at the time the amendment, suspension or termination was approved;
provided, however, any amendment, suspension or termination may be effected,
even if so approved after such a public announcement, if (a) the amendment,
suspension or termination is approved after any plans have been abandoned to
effect the transaction which, if effected, would have constituted a Change in
Control and the event which would have constituted the Change in Control has not
occurred, and (b) within a period of six months after such approval, no other
event constituting a Change in Control shall have occurred, and no public
announcement of a proposed event which would constitute a Change in Control
shall have been made, unless thereafter any plans to effect the Change in
Control have been abandoned and the event which would have constituted the
Change in Control has not occurred. Any amendment, suspension or termination of
the Plan which is so approved prior to a Change in Control at the request of a
third party who effectuates a Change in Control shall be deemed to be an
amendment, suspension or termination approved during the Benefit Protection
Period.

      7. GENERAL.

         (a) No Right of Employment.

             Nothing contained in the Plan nor any action of the Committee
pursuant to the Plan shall give any employee any right to remain in the employ
of the Corporation or to impair the Corporation's right to terminate the
employment of any employee at any time, with or without cause, which right is
hereby reserved.

         (b) Designation of Beneficiaries.

             Participants may designate on the prescribed form one or more
Beneficiaries to whom distribution shall be made of any outstanding Account
balance at the time of the Participant's death. A Participant may change such
designation at any time by filing the prescribed form with the Committee. If a
Beneficiary has not been designated or if no designated Beneficiary survives the
Participant, distribution will be made to the Participant's surviving spouse as
Beneficiary if then living or, if not, in equal shares to the then living
children of the Participant as Beneficiaries or, if none, to the Participant's
estate as Beneficiary.

         (c) Domestic Relations Orders.

             The procedures established by the Corporation for the determination
of the qualified status of domestic relations orders and for making
distributions under qualified domestic relations orders, as provided in Section
206(d) of ERISA, shall apply to the Plan.

         (d) Costs of the Plan.

             The costs and expenses of administering the Plan shall be borne by
the Corporation.

                                       4
<PAGE>

         (e) Severability.

             The provisions of the Plan shall be deemed severable and the
validity or unenforceability of any provision shall not affect the validity or
enforceability of the other provisions hereof.

         (f) Binding Effect of Plan.

             The Plan shall be binding upon and shall inure to the benefit of
the Corporation, its successors and assigns, and the Corporation shall require
any successor or assign to expressly assume and agree to perform the Plan in the
same manner and to the same extent that the Corporation would be required to
perform it if no such succession or assignment had taken place. The term "the
Corporation" as used herein shall include such successors and assigns. The term
"successors and assigns" as used herein shall mean a corporation or other entity
acquiring all or substantially all the assets and business of the Corporation
(including the Plan) whether by operation of law or otherwise.

         (g) No Waiver of Breach.

             No waiver by either party hereto at any time of any breach by the
other party hereto of, or compliance with, any condition or provision of the
Plan to be performed by such other party shall be deemed a waiver of similar or
dissimilar provisions of conditions at the same or at any prior or subsequent
time.

         (h) No Assignment.

             The interest and property rights of any Participant under the Plan
shall not be subject to option nor be assignable either by voluntary or
involuntary assignment or by operation of law, including (without limitation)
bankruptcy, garnishment, attachment or other creditor's process, and any act in
violation of this Section 7(i) shall be void.

         (i) Applicable Law.

            The Plan shall be administered, construed and governed in accordance
with ERISA and, to the extent not preempted by ERISA, the laws of the State of
California.

         (j) Participant's Rights Unsecured.

             This Plan is not intended and shall not be construed to require the
Corporation to fund any of the benefits provided hereunder or to establish a
trust for such purpose. The interest under the Plan of any Participant and such
Participant's right to receive a distribution of his or her Account shall be an
unsecured claim against the general assets of the Corporation. The Account shall
be a bookkeeping entry only and no Participant shall have any interest in or
claim against any specific asset of the Company pursuant to the Plan.

                                       5
<PAGE>

         (k) Authority to Establish a Grantor Trust.

             The Committee is authorized in its sole discretion to establish a
grantor trust for the purpose of providing security for the payment of benefits
under the Plan; provided, however, that no Participant shall be considered to
have a beneficial ownership interest (or any other sort of interest) in any
specific asset of the Corporation or of its subsidiaries or affiliates as a
result of the creation of such trust or the transfer of funds or other property
to such trust.

         (l) Other Benefit Plans.

             To the extent permitted by applicable law, a Participant's deferral
elections made pursuant to this Plan shall be disregarded for purposes of
determining the Participant's benefits under any other benefit plan or program
established or maintained by the Corporation or its Subsidiaries.
