                        STANDARD TERMS AND CONDITIONS FOR
                        LONG-TERM CASH AWARD - EMPLOYEES

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.


                                       2



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.


                                       3



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
than forum costs associated with the arbitration) incurred by it or him or her
in connection with the resolution of the dispute. By


                                       4



accepting the Cash Award, the Participant consents to all of the terms and
conditions of this Agreement (including, without limitation, this Section 11).

construed in accordance with the laws of the State of Delaware (without regard
to conflict of law principles thereunder) and applicable federal law.

13.     DEFERRALS; CONSTRUCTION

        (a) To the extent permitted under the Corporation's Amended and Restated
Deferred Compensation Plan, as amended from time to time, Participant may elect
to defer receipt of any or all Cash Award Payment Amounts due hereunder. Such
election shall be made, and any such deferral shall be effected and
administered, in accordance with the Deferred Compensation Plan.

        (b) This Agreement shall be construed and interpreted to comply with
Section 409A. The Corporation reserves the right to amend this Agreement to the
extent it reasonably determines is necessary in order to preserve the intended
tax consequences of the Cash Award in light of Section 409A and any regulations
or other guidance promulgated thereunder.

14.     SEVERABILITY

        If the arbitrator selected in accordance with Section 11 or a court of

policy, then only the portions of this Agreement or the Plan, as applicable,
which are found to violate such statute or public policy shall be stricken, and
all portions of this Agreement and the Plan which are not found to violate any
statute or public policy shall continue in full force and effect. Furthermore,
it is the parties' intent that any order striking any portion of this Agreement
and/or the Plan should modify the stricken terms as narrowly as possible to give
as much effect as possible to the intentions of the parties hereunder.

15.     ENTIRE AGREEMENT

        This Agreement (including these Standard Terms) and the Plan together
constitute the entire agreement and supersede all prior understandings and
agreements, written or oral, of the parties hereto with respect to the subject
matter hereof. The Plan and this Agreement may be amended pursuant to Section
8.6 of the Plan. Such amendment must be in writing and signed by the
Corporation. The Corporation may, however, unilaterally waive any provision
hereof in writing to the extent such waiver does not adversely affect the
interests of the Participant hereunder, but no such waiver shall operate as or
be construed to be a subsequent waiver of the same provision or a waiver of any
other provision hereof.
