1.      LONG-TERM CASH AWARD SUBJECT TO 2004 PERFORMANCE INCENTIVE PLAN

        The Long-Term Cash Award (the "CASH AWARD") referred to in the attached
Notice of Grant of Long-Term Cash Award and Long-Term Cash Award Agreement -
Employees (the "NOTICE") is awarded under the Western Digital Corporation (the
"CORPORATION") Amended and Restated 2004 Performance Incentive Plan (the
"PLAN"). The Cash Award is subject to the terms and provisions of the Notice,
these Standard Terms and Conditions for Long-Term Cash Award - Employees (these
"STANDARD TERMS"), and the Plan. To the extent any information in the Notice or
other information provided by the Corporation conflicts with the Plan and/or
these Standard Terms, then the Plan or these Standard Terms, as applicable,
shall control. To the extent any terms and provisions in these Standard Terms
conflict with the terms and provisions of the Plan, the Plan shall control. The
Notice and these Standard Terms, together, constitute the "AGREEMENT" with
respect to the Cash Award pursuant to Section 5.3 of the Plan. The holder of the
Cash Award is referred to herein as the "PARTICIPANT." Capitalized terms not
defined herein have the meanings set forth in the Plan.

2.      PERFORMANCE GOALS

        The Compensation Committee of the Board of Directors of the Corporation
(the "COMMITTEE") shall set one or more objective performance goals for
Participant for the Measurement Period, in accordance with Section 5.2 of the
Plan ("PERFORMANCE GOALS"). Upon determination by the Committee of the
Performance Goals, the Performance Goals for the Measurement Period shall be
attached as Exhibit A hereto.

3.      DETERMINATION AND PAYMENT OF CASH AWARD PAYMENT AMOUNT

        Within a reasonable period of time following the end of the Measurement
Period, the Committee shall determine, in accordance with the Performance Goals
and related criteria and methodology established by the Committee described on
Exhibit A hereto, the extent to which the Performance Goals have been achieved
and authorize the cash payment of an award, if any, to Participant (the "CASH
AWARD PAYMENT AMOUNT"). The Cash Award Payment Amount shall equal the dollar
amount of the Cash Award set forth on the Notice of Grant of Cash Performance
Award ("TARGET CASH AWARD") multiplied by a percentage that shall be determined
by the Committee in accordance with the Performance Goals and related criteria
and methodology described on Exhibit A hereto (the "CASH AWARD PERFORMANCE
PERCENTAGE"), subject to adjustment as described in this Agreement. Subject to
Sections 5 and 6 below, payment of the Cash Award Payment Amount shall be made
to Participant or, in the event of Participant's death, to Participant's legal
representative, as soon as practicable after the certification of awards by the
Committee (but no later than seventy-five days following completion of the
Measurement Period), net of amounts withheld in satisfaction of the requirements
of Section 8(b) below. THE CASH AWARD PERFORMANCE PERCENTAGE AND THE CASH AWARD
PAYMENT AMOUNT ARE SUBJECT TO ADJUSTMENT (WHICH MAY REDUCTION) AS PROVIDED IN
THIS AGREEMENT.

4.      TERMINATION AT PAYMENT OF CASH AWARD

        Unless terminated earlier under Section 5 below, a Participant's rights
under this Agreement with respect to the Cash Award awarded under this Agreement
shall terminate at the time any Cash Award Payment Amount is paid to Participant
or at such time that the Cash Award is no longer eligible to become paid, as
determined by the Administrator or the Committee.

<PAGE>
5.      TERMINATION OF EMPLOYMENT; CHANGE IN CONTROL EVENTS

        Subject to Section 7.2 or 7.3 of the Plan and subject to adjustment as
provided in Section 6 hereof, if the Participant ceases to be employed by or to
provide services to the Corporation and its Subsidiaries (regardless of the
reason for such termination, whether with or without cause, voluntarily or
involuntarily, or due to disability), the Participant's Cash Award and any right
to receive a Cash Award Payment Amount shall terminate to the extent a Cash
Award Payment Amount has not yet been determined by the Committee as described
in Section 3, as of the date the Participant's employment or services terminate;
provided, however, that in the event of the Participant's death at a time when
the Participant is employed by or providing services to the Corporation or any
of its Subsidiaries, a pro-rata portion of the Cash Award Payment Amount shall
be paid (equal to the Cash Award Payment Amount that the Participant would have
been entitled to had he or she continued to be employed through the applicable
payment date, multiplied by a fraction the numerator of which is the number of
days in the Measurement Period that the Participant was employed by the
Corporation or one of its Subsidiaries prior to the Participant's death and the
denominator of which is the total number of days in the Measurement Period) to
the Participant's legal representative at the same time as Cash Award Payment
Amounts are paid generally with respect to the Measurement Period. The
Administrator shall be the sole judge, for purposes of the Cash Award, as to
whether the Participant continues to render services the Corporation or its
Subsidiaries and the date, if any, upon which such services shall be deemed to
have terminated.

6.      ADJUSTMENTS; PERFORMANCE-BASED COMPENSATION

        (a) Adjustments. In determining the Cash Award Performance Percentage
and the Cash Award Payment Amount with respect to the Measurement Period, the
Committee may adjust the Performance Goals previously determined by the
Committee to the extent permitted pursuant to Section 5.2.2 of the Plan.

        (b) Reduction of Cash Award Payment Amount. Notwithstanding Section 3 or
any other term of this Agreement, the Committee may in its sole and absolute
discretion reduce the Cash Award Payment Amount, if the Committee determines
that such reduction is necessary or advisable due to current business conditions
or for any other reason, including the Committee's judgment that the Performance
Goals have become an inappropriate measure of achievement, a change in the
employment status, position or duties of the Participant, unsatisfactory
performance of the Participant, or the Participant's service for less than the
Measurement Period.

        (c) Performance-Based Compensation. Cash Awards are intended to be
Performance-Based Awards based on Business Criteria, as described in Section 5.2
of the Plan. Compensation attributable to the Agreement is intended to
constitute qualified performance-based compensation under Section 162(m) of the
Code and the regulations thereunder. This Agreement shall be construed and
administered by the Committee in a manner consistent with this intent.

7.      ACKNOWLEDGMENT OF NATURE OF PLAN AND CASH AWARDS

In accepting the Cash Award, Participant acknowledges that:

        (a) the Plan is established voluntarily by the Corporation, it is
discretionary in nature and may be modified, amended, suspended or terminated by
the Corporation at any time, as provided in the Plan;

        (b) the Award of this Cash Award is voluntary and occasional and does
not create any contractual or other right to receive future awards of Cash
Awards, or benefits in lieu of Cash Awards even if Cash Awards have been awarded
repeatedly in the past;

        (c) all decisions with respect to future awards, if any, will be at the
sole discretion of the Corporation; and

        (d) Participant's participation in the Plan is voluntary.

8.      TAXES

        (a) Responsibility for Tax-Related Items. Regardless of any action the
Corporation or Participant's actual employer takes with respect to any or all
income tax (including federal, state and local taxes), social insurance, payroll
tax or other tax-related withholding ("TAX RELATED ITEMS"), Participant
acknowledges that the ultimate liability for all Tax Related Items legally due
by Participant is and remains Participant's responsibility and that the
Corporation and/or the Participant's actual employer (i) make no representations
or undertakings regarding the treatment of any Tax Related Items in connection
with any aspect of the Cash Award, including the grant of the Cash Award, the
determination of the Cash Award Payment Amount or the payment of the Cash Award
Payment Amount; and (ii) do not commit to structure the terms of the grant or
any aspect of the Cash Award to reduce or eliminate the Participant's liability
for Tax Related Items.

        (b) Withholding Taxes. The Corporation (or any of its Subsidiaries last
employing the Participant) shall be entitled to withhold from any Cash Award
Payment Amount an amount necessary to satisfy any withholding obligations of the
Corporation or any Subsidiary with respect to such payment.

9.      NONTRANSFERABILITY

        Prior to the time that a Cash Award Payment Amount is paid to
Participant, no Cash Award or right to receive a Cash Award Payment Amount, any
interest therein, nor any amount payable in respect thereof, may be sold,
assigned, transferred, pledged or otherwise disposed of, alienated or
encumbered, either voluntarily or involuntarily. The transfer restrictions in
the preceding sentence shall not apply to (a) transfers to the Corporation, or
(b) subject to Section 5, transfers by will or the laws of descent and
distribution.

10.     NO RIGHT TO EMPLOYMENT

        Nothing contained in this Agreement or the Plan constitutes an
employment or service commitment by the Corporation or any of its Subsidiaries,
affects the Participant's status, if he or she is an employee, as an employee at
will who is subject to termination without cause, confers upon the Participant
any right to remain employed by or in service to the Corporation or any
Subsidiary, interferes in any way with the right of the Corporation or any
Subsidiary at any time to terminate such employment or service, or affects the
right of the Corporation or any Subsidiary to increase or decrease the
Participant's other compensation.

11.     ARBITRATION

        Any controversy arising out of or relating to this Agreement (including
these Standard Terms) and/or the Plan, their enforcement or interpretation, or
because of an alleged breach, default, or misrepresentation in connection with
any of their provisions, or any other controversy arising out of or related to
the Cash Award, including, but not limited to, any state or federal statutory
claims, shall be submitted to arbitration in Orange County, California, before a
sole arbitrator selected from Judicial Arbitration and Mediation Services, Inc.,
Orange, California, or its successor ("JAMS"), or if JAMS is no longer able to
supply the arbitrator, such arbitrator shall be selected from the American
Arbitration Association, and shall be conducted in accordance with the
provisions of California Code of Civil Procedure Sections 1280 et seq. as the
exclusive forum for the resolution of such dispute; provided, however, that
provisional injunctive relief may, but need not, be sought by either party to
this Agreement in a court of law while arbitration proceedings are pending, and
any provisional injunctive relief granted by such court shall remain effective
until the matter is finally determined by the arbitrator. Final resolution of
any dispute through arbitration may include any remedy or relief which the
arbitrator deems just and equitable, including any and all remedies provided by
applicable state or federal statutes. At the conclusion of the arbitration, the
arbitrator shall issue a written decision that sets forth the essential findings
and conclusions upon which the arbitrator's award or decision is based. Any
award or relief granted by the arbitrator hereunder shall be final and binding
on the parties hereto and may be enforced by any court of competent
jurisdiction. The parties acknowledge and agree that they are hereby waiving any
rights to trial by jury in any action, proceeding or counterclaim brought by
either of the parties against the other in connection with any matter whatsoever
arising out of or in any way connected with any of the matters referenced in the
first sentence above. The parties agree that Corporation shall be responsible
for payment of the forum costs of any arbitration hereunder, including the
arbitrator's fee. The parties further agree that in any proceeding with respect
to such matters, each party shall bear its own attorney's fees and costs (other

in connection with the resolution of the dispute. By

13.     DEFERRALS; CONSTRUCTION

        (a) To the extent permitted under the Corporation's Amended and Restated

Subsidiary's) bonus program in which the Participant participates for the bonus
cycle in which the Participant's date of termination occurs (with such pro-rata
portion based on the number of days in the applicable bonus cycle during which
the Participant was employed (not to exceed six (6) months) and assuming 100% of
the performance target(s) subject to the bonus award are met regardless of
actual funding by the Company or a Subsidiary). The payment shall be paid in one
lump-sum cash payment within thirty (30) days of the Participant's compliance
with all provisions of Section 7.

        6.4 Equity Awards. Notwithstanding anything in the applicable stock
incentive plan and/or award agreement to the contrary, upon a Participant's
termination of employment, the Participant's then outstanding stock options and
restricted stock or stock unit awards that are subject to time-based vesting
will vest and become exercisable or payable, as applicable, as if the
Participant had remained employed with the Company or a Subsidiary for an
additional six (6) months. For avoidance of doubt, the foregoing is not intended
to apply to any equity awards held by the Participant that are subject to
performance-based vesting or to supersede any more favorable provision in any
stock incentive plan and/or award agreement regarding accelerated vesting in the
event of the Participant's termination of employment. Notwithstanding anything
to the contrary herein, the post-termination exercisability of the Participant's
then outstanding stock options shall continue to be governed by the stock
incentive plan and stock option agreement applicable to such options.

<PAGE>
        6.5 Outplacement Services. A Participant shall be eligible for
outplacement services, provided by a vendor chosen by the Company or applicable
Subsidiary and at the Company's or applicable Subsidiary's expense, after the
Participant's termination of employment for up to the number of months set forth
below:

                (a) Tier I Executive: 12 months

                (b) Tier II Executives: 12 months

                (c) Tier III Executive: 12 months

        6.6 Continued Health Care Coverage. If the Participant elects COBRA
continuation coverage within the applicable election period, the Company or
applicable Subsidiary shall make the applicable COBRA premium payments following
the expiration of the Participant's company-provided medical, dental, and/or
vision coverage existing as of the Participant's termination date for the number
of months set forth below:

                (a) Tier I Executive: 24 months

                (b) Tier II Executives: 18 months

                (c) Tier III Executive: 12 months

        Notwithstanding anything in the Plan to the contrary, there shall be no
obligation to make such COBRA premium payments on behalf of any Participant if
the Participant otherwise becomes eligible for equivalent coverage under another
employer's plan.

7.      CONDITIONS TO SEVERANCE BENEFITS

        7.1 Release. Notwithstanding anything to the contrary contained herein,
the Company's or applicable Subsidiary's obligation to pay benefits to a
Participant under Section 6 is subject to the condition precedent that the
Participant execute a valid and effective release of any and all claims in a
form and manner acceptable to the Company, and such release is received by the
Company no earlier than, and no later than fourteen (14) days (or such other
period as required by law) after, the Participant's termination date and is not
revoked by the Participant (pursuant to any revocation rights afforded by
applicable law) or otherwise rendered unenforceable by the Participant.
Notwithstanding anything else contained herein to the contrary, the Company or
applicable Subsidiary will have no obligation to pay any benefit to the
Participant under the Plan unless and until that Participant's release (in such
form) has been fully executed by the Participant (and the Participant's spouse,
to the extent required by the Company), has been received by the Company, and
has become effective and irrevocable by the Participant.

        7.2 Departure and Entitlement Procedure. As a condition to becoming a
Participant and receiving the severance benefits described in Section 6, the
Executive must return and deliver to the Administrator or his or her designee
all Company and Subsidiary property within seven (7) days of the Executive's
termination date. In addition, except as otherwise provided by

<PAGE>
the Company, if an Executive resigns prior to his/her scheduled termination
date, then he/she shall not be entitled to any severance payments or any other
severance benefits provided herein.

        7.3 Offsets. Except as expressly provided below, a Participant shall not
be required to mitigate the amount of any payments provided for by the Plan by
seeking employment or otherwise, nor shall the amount of any cash payments or
benefits provided under the Plan be reduced by any compensation or benefits
earned by the Participant after his or her termination of employment with the
Company or applicable Subsidiary. All severance payments under the Plan shall be
subject to legal deductions, and the Company and/or applicable Subsidiary
reserves the right to offset the benefits payable under the Plan by any advanced
monies the Participant owes the Company or a Subsidiary. The benefits and
amounts payable under the Plan shall be reduced (but not below zero) by any
severance pay or benefits to which a Participant is or becomes entitled under
any other severance pay plan, policy, agreement or arrangement. In addition, in
no event shall a Participant become entitled to a duplication of benefits under
the Plan and any other severance plan or program of the Company or a Subsidiary.
Without limiting the generality of the foregoing, in no event shall a
Participant receive benefits under the Plan in connection with his her
termination of employment if such Participant is entitled to benefits under the
Company's Amended and Restated Change of Control Severance Plan in connection
with such termination of employment. Notwithstanding any provision of the Plan
to the contrary, to the extent that any Participant is entitled to any period of
paid notice under Federal or state law including, but not limited to, the Worker
Adjustment Retraining Notification Act, 29 U.S.C. Sections 2101 et seq., the
benefits and amounts payable under the Plan shall be reduced (but not below
zero) by the Base Pay received by the Participant during the period of such paid
notice.

        7.4 Limitation On Employee Rights. The Plan shall not give any employee
the right to be retained in the service of the Company or to interfere with or
restrict the right of the Company or applicable Subsidiary to discharge any
employee at any time, with or without Cause.

8.      RESOLUTION OF DISPUTES

        8.1 Claim. If a Participant or any other individual (herein referred to
as a "Claimant") believes that benefits under the Plan are being wrongfully
denied, that the Plan is not being operated properly, that fiduciaries of the
Plan have breached their duties, or that the Claimant's legal rights are being
violated with respect to the Plan, the Claimant must file a formal claim with
the Administrator. Any such claim for benefits must be filed in writing within
90 days of the date upon which the Participant first knew or should have known
the facts upon which the claim is based.

        8.2 Claim Decision. If any claim for benefits under the Plan is denied,
in whole or in part, the Claimant shall be so notified by the Administrator
within thirty (30) calendar days of the date such person's claim is delivered to
the Administrator. At the same time, the Administrator shall notify the Claimant
of his or her right to a review by the Administrator and shall set forth, in a
manner calculated to be understood by the Claimant, specific reasons for such
decision, specific references to pertinent Plan provisions on which the decision
is based, a description of any additional material or information necessary for
the Claimant to perfect his or her request for

<PAGE>
review, an explanation of why such material or information is necessary, and an
explanation of the Plan's review procedure.

        8.3 Request for Review. Any Claimant or duly authorized representative
may appeal from such decision by submitting to the Administrator within sixty
(60) calendar days after the date of such notice of its decision a written
statement:

                (a) requesting a review of the claim for benefits by the
        Administrator;

                (b) setting forth all of the grounds upon which the request for
        review is based and any facts in support thereof; and

                (c) setting forth any issues or comments which the Claimant
        deems relevant to the claim.

        The Administrator shall act upon such appeal within sixty (60) calendar
days after the latter of receipt of the Claimant's request for review by it or
receipt of all additional materials reasonably requested by it from such
Claimant.

        8.4 Review of Decision. The Administrator shall make a full and fair
review of an appeal and all written materials submitted by the Claimant in
connection therewith and may require the Claimant to submit, within ten (10)
calendar days of written notice by the Administrator, such additional facts,
documents or other evidence as the Administrator, in its sole discretion, deems
necessary or advisable in making such a review. On the basis of its review, the
Administrator shall make an independent determination of the Claimant's
eligibility for an allowance and the amount of such allowance, if any, under
this Plan. The decision of the Administrator on any appeal shall be final and
conclusive upon all persons if supported by substantial evidence in the record.

        8.5 Denial on Review. If on review of a decision, the Administrator
denies a claim in whole or in part, it shall give written notice of its decision
to the Claimant setting forth, in a manner calculated to be understood by the
Claimant, the specific reasons for such denial and specific references to the
pertinent Plan provisions on which its decision was based. If a Claimant
believes that the Administrator's determination on appeal is incorrect, the
Claimant or duly authorized representative may invoke the arbitration procedures
described in Section 8.6 or file suit related to such determination; provided
that any legal action must be taken by the Claimant within ninety (90) days
after the date upon which the Administrator's written decision on review was
sent to the Claimant.

        8.6 Arbitration. A Claimant who has followed the procedures in Sections
8.1 through 8.5, but who has not obtained full relief on his or her claim for
benefits, may, within ninety (90) days following his or her receipt of the
Administrator's written decision on review pursuant to Section 8.5, apply in
writing to the Administrator for expedited and binding arbitration of his or her
claim in Orange County, California, before a sole arbitrator selected from
Judicial Arbitration and Mediation Services, Inc., Orange County, California, or
its successor ("JAMS"), or if JAMS is no longer able to supply the arbitrator,
such arbitrator shall be selected from the American

<PAGE>
Arbitration Association, and shall be conducted in accordance with the
provisions of California Code of Civil Procedure Sections 1280 et seq. as the
exclusive forum for the resolution of such dispute. Pursuant to California Code
of Civil Procedure Section 1281.8, provisional injunctive relief may, but need
not, be sought by the Company, a Subsidiary or an Executive in a court of law
while arbitration proceedings are pending, and any provisional injunctive relief
granted by such court shall remain effective until the matter is finally
determined by the Arbitrator. Final resolution of any dispute through
arbitration may include any remedy or relief which the Arbitrator deems just and
equitable, including any and all remedies provided by applicable state or
federal statutes. At the conclusion of the arbitration, the Arbitrator shall
issue a written decision that sets forth the essential findings and conclusions
upon which the Arbitrator's award or decision is based. Any award or relief
granted by the Arbitrator hereunder shall be final and binding on the parties
hereto and may be enforced by any court of competent jurisdiction. Any rights to
trial by jury in any action, proceeding or counterclaim brought by any of the
Company, a Subsidiary or an Executive in connection with any matter whatsoever
arising out of or in any way connected with the Plan are hereby waived. The
Company or applicable Subsidiary shall be responsible for payment of the forum
costs of any arbitration hereunder, including the Arbitrator's fee. In any
proceeding to enforce the terms of the Plan, the prevailing party shall be
entitled to its or his reasonable attorneys' fees and costs (other than forum
costs associated with the arbitration) incurred by it or him in connection with
resolution of the dispute in addition to any other relief granted.

        8.7 Legal Fees and Expenses. If any dispute arises between the parties
with respect to the interpretation or performance of the Plan, the prevailing
party in any arbitration or proceeding shall be entitled to recover from the
other party its attorneys' fees, arbitration or court costs and other expenses
incurred in connection with any such proceeding. Amounts, if any, paid to the
Executive under this Section 8.7 shall be in addition to all other amounts due
to the Executive pursuant to the Plan.

9.      ADMINISTRATION

        9.1 Administrator. Except as provided herein, the Plan shall be
administered and operated by the Administrator. The Administrator is empowered
to construe and interpret the provisions of the Plan and to decide all questions
of eligibility for benefits under the Plan and shall make such determinations in
its sole and absolute discretion. The Administrator may at any time delegate to
any other named person or body, or reassume therefrom, any of its
responsibilities or administrative duties with respect to the Plan.

        9.2 Experts; Rules. The Administrator may contract with one or more
persons to render advice with regard to any responsibility it has under the
Plan. Subject to the limitations of the Plan, the Administrator shall from time
to time establish such rules for the administration of the Plan as it may deem
desirable.

        9.3 Indemnity. The Company shall, to the extent permitted by law, by the
purchase of insurance or otherwise, indemnify and hold harmless the
Administrator and each other fiduciary with respect to the Plan for liabilities
or expenses they and each of them incur in carrying out

<PAGE>
their respective duties under the Plan, other than for any liabilities or
expenses arising out of such fiduciary's gross negligence or willful misconduct.

10.     AMENDMENT

        The Committee (or the Board) reserves the right to amend, suspend and/or
terminate the Plan at any time in its sole discretion. No amendment, suspension
or termination shall diminish benefits to which a Participant is currently
entitled under the Plan. Any modification or other amendment of the Plan shall
be in writing, signed by either the Company's Chief Executive Officer or Vice
President, Human Resources.

11.     GENERAL

        11.1 Assignment by Participants. None of the benefits, payments,
proceeds or claims of any Executive or Participant shall be subject to any claim
of any creditor and, in particular, the same shall not be subject to attachment
or garnishment or other legal process by any creditor, nor shall any such
Executive have any right to alienate, anticipate, commute, pledge, encumber or
assign any of the benefits or payments or proceeds that he or she may expect to
receive, contingently or otherwise, under the Plan. Notwithstanding the
foregoing, benefits that are in pay status may be subject to a court order of
garnishment or wage assignment, or similar order, or a tax levy. The Plan shall
inure to the benefit of and be enforceable by each Participant's personal or
legal representatives, executors, administrators, successors, heirs,
distributees, devisees, and legatees. If a Participant dies while any amount
would still be payable to him or her hereunder had he or she continued to live,
all such amounts, unless otherwise provided herein, shall be paid to the
Participant's beneficiary in accordance with the terms of the Plan.

        11.2 Binding Effect. The Company or applicable Subsidiary will require
any successor (whether by purchase of assets, merger, consolidation or
otherwise) to all or substantially all of the business and/or assets of the
Company or applicable Subsidiary to expressly assume and agree to perform all of
the obligations of the Company or applicable Subsidiary under the Plan
(including the obligation to cause any subsequent successor to also assume the
obligations of the Plan) unless such assumption occurs by operation of law. For
avoidance of doubt, in the event that a successor of a Subsidiary (whether by
purchase of assets, merger, consolidation or otherwise) assumes the Subsidiary's
obligations under the Plan, the Company will have no obligations under the Plan
with respect to the Executives employed by such Subsidiary.

        11.3 No Waiver. No waiver of any term, provision or condition of the
Plan, whether by conduct or otherwise, in any one or more instances shall be
deemed or be construed as a further or continuing waiver of any such term,
provision or condition or as a waiver of any other term, provision or condition
of the Plan.

        11.4 Expenses; Unsecured General Creditor. The benefits and costs of the
Plan shall be paid by the Company and/or a Subsidiary out of its general assets.
The status of a claim against the Company or a Subsidiary with respect to the
benefits provided hereunder shall be same as the status of a claim against the
Company or applicable Subsidiary by any general or unsecured creditor.

<PAGE>
        11.5 ERISA. The Plan is an unfunded compensation arrangement for a
select group of management or highly compensated employees of the Company or a
Subsidiary and any exemptions under ERISA applicable to such an arrangement
shall be applicable to the Plan.

        11.6 Section 409A. The Plan shall be construed and interpreted so as to
avoid the imputation of any tax liability (penalty or otherwise) pursuant to
Section 409A of the Code. The Company may suspend the payment of any benefit
pursuant to the Plan to any "specified employee" (within the meaning of Section
409A of the Code) to a date no earlier than the date that is six months after
the employee's separation of service to the extent, if any, the Administrator
determines that such suspension is reasonably necessary to satisfy Code Section
409A(a)(2)(B)(i) (in which case the benefits that would have otherwise been paid
during such six month period shall be paid, without interest, as soon as
practical following the end of such six month period).

        11.7 WARN Act. Benefits payable under the Plan are intended to satisfy,
where applicable, any Company obligations under the Federal Worker Adjustment
and Retraining Notification Act and any similar obligations that the Company or
its Subsidiaries may have under any successor or other severance pay statute.

        11.8 Construction. The masculine pronoun shall include the feminine
pronoun and the feminine pronoun shall include the masculine pronoun and the
singular pronoun shall include the plural pronoun and the plural pronoun shall
include the singular pronoun, unless the context clearly indicates otherwise.

        11.9 Governing Law. The Plan shall be construed according to the laws of
the State of California, except to the extent such laws are preempted by federal
law.

        11.10 Severability. If any provision of the Plan is held to be illegal,
invalid or unenforceable under any present or future law, and if the rights or
obligations of any party hereto under the Plan will not be materially and
adversely affected hereby, (i) such provision will be fully severable, (ii) the
Plan will be construed and enforced as if such illegal, invalid or unenforceable
provision had never comprised a part hereof, (iii) the remaining provisions of
the Plan will remain in full force and effect and will not be affected by the
illegal, invalid or unenforceable provision or by its severance herefrom and
(iv) in lieu of such illegal, invalid or unenforceable provision, there will be
added automatically as a part of the Plan a legal, valid and enforceable
provision as similar in terms to such illegal, invalid or unenforceable
provision as may be possible.

<PAGE>
        11.11 Notices. Any notice required or permitted by the Plan shall be in
writing, delivered by hand, or sent by registered or certified mail, return
receipt requested, or by recognized courier service (regularly providing proof
of delivery), addressed as follows:
