                                   ARTICLE I
                              NAME OF CORPORATION

                        The name of this corporation is:

                          WESTERN DIGITAL CORPORATION

                                   ARTICLE II
                               REGISTERED OFFICE

         The address of the registered office of the corporation in the State

                                  ARTICLE III
                                    PURPOSE

         The purpose of the corporation is to engage in any lawful act or
activity for which corporations may be organized under the General Corporation
Law of the State of Delaware.

                                   ARTICLE IV
                            AUTHORIZED CAPITAL STOCK

         The corporation shall be authorized to issue two classes of shares of
stock to be designated, respectively, "Preferred Stock" and "Common Stock"; the
total number of shares which the corporation shall have authority to issue is
230 Million (230,000,000); the total number 


                                       1
   2

of shares of Preferred Stock shall be Five Million (5,000,000) and each such 
share shall have a par value of one cent ($0.01); and the total number of 
shares of Common Stock shall be 225 Million (225,000,000) and each such 
share shall have a par value of one cent ($0.01).

         The shares of Preferred Stock may be issued from time to time in one
or more series.  The Board of Directors is hereby vested with authority to fix
by resolution or resolutions the designations and the powers, preferences and
relative, participating, optional or other special rights, and qualifications,
limitations or restrictions thereof, including without limitation the dividend
rate, conversion rights, redemption price and liquidation preference, of any
series of shares of Preferred Stock, and to fix the number of shares
constituting any such series, and to increase or decrease the number of shares
of any such series (but not below the number of shares thereof then
outstanding).  In case the number of shares of any such series shall be so
decreased, the shares constituting such decrease shall resume the status which
they had prior to the adoption of the resolution or resolutions originally
fixing the number of shares of such series.

                                   ARTICLE V
                 SERIES A JUNIOR PARTICIPATING PREFERRED STOCK

         Section 1.       Designation and Amount.  The Board of Directors has
designated a series of Preferred Stock as "Series A Junior Participating
Preferred Stock" and the number of shares constituting such series shall be
500,000.  Such number of shares may be increased or decreased by resolution of
the Board of Directors; provided, that no decrease shall reduce the number of
shares of Series A Junior Participating Preferred Stock to a number less than
the number of shares then outstanding plus the number of shares reserved for
issuance upon the exercise of outstanding options, rights or warrants or upon
the conversion of any outstanding securities issued by the corporation
convertible into Series A Junior Participating Preferred Stock.

         Section 2.       Dividends and Distributions.

         (A)     Subject to the prior and superior rights of the holders of any
shares of any series of Preferred Stock ranking prior and superior to the
shares of Series A Preferred Stock with respect to dividends, the holders of
shares of Series A Preferred Stock shall be entitled to receive, when, as and
if declared by the Board of Directors out of funds legally available for the
purpose, quarterly dividends payable in cash on the 15th day of January, April,
July and October in each year (each such date being referred to herein as a
"Quarterly Dividend Payment Date"), commencing on the first Quarterly Dividend
Payment date after the first issuance of a share or fraction of a share of
Series A Preferred Stock, in an amount per share (rounded to the nearest cent)
equal to the greater of (a) $0.25 or (b) subject to the provision for
adjustment hereinafter set forth, 100 times the aggregate per share amount of
all cash dividends, and 100 times the aggregate per share amount (payable in
kind) of all non-cash dividends or other distributions other than a dividend
payable in shares of Common Stock or a subdivision of the outstanding shares of
Common Stock (by reclassification or otherwise), declared on the Common Stock
since the immediately preceding Quarterly Dividend Payment Date, or, with
respect to the first Quarterly Dividend Payment Date, since the first issuance
of any share or fraction of a share of Series A Preferred Stock.  In the event
the corporation shall at any time after December 1, 1988 (the "Rights
Declaration Date") (i) declared any dividend on Common Stock payable in shares
of



                                        2
   3
Common Stock, (ii) subdivide the outstanding Common Stock or (iii) combine the
outstanding Common Stock into a smaller number of shares, then in each such
case the amount to which holders of shares of Series A Preferred Stock were
entitled immediately prior to such event under clause (b) of the preceding
sentence shall be adjusted by multiplying such amount by a fraction the
numerator of which is the number of shares of Common Stock outstanding
immediately after such event and the denominator of which is the number of
shares of Common Stock that were outstanding immediately prior to such event.

         (B)     The corporation shall declare a dividend or distribution on
the Series A Preferred Stock as provided in paragraph (A) above immediately
after it declares a dividend or distribution on the Common Stock (other than a
dividend payable in shares of Common Stock); provided that, in the event no
dividend or distribution shall have been declared on the Common Stock during
the period between any Quarterly Dividend Payment Date, a dividend of $0.25 per
share on the Series A Preferred Stock shall nevertheless be payable on such
subsequent Quarterly Dividend Payment Date.

         (C)     Dividends shall begin to accrue and be cumulative on
outstanding shares of Series A Preferred Stock from the Quarterly Dividend
Payment Date next preceding the date of issue of such shares of Series A
Preferred Stock, unless the date of issue of such shares is prior to the record
date for the first Quarterly Dividend Payment Date, in which case dividends on
such shares shall begin to accrue from the date of issue of such shares, or
unless the date of issue is a Quarterly Dividend Payment Date or is a date
after the record date for the determination of holders of shares of Series A
Preferred Stock entitled to receive a quarterly dividend and before such
Quarterly Dividend Payment Date, in either of which events such dividends shall
begin to accrue and be cumulative from such Quarterly Dividend Payment Date.
Accrued but unpaid dividends shall not bear interest.  Dividends paid on the
shares of Series A Preferred Stock in an amount less than the total amount of
such dividends at the time accrued and payable on shares shall be allocated pro
rata on a share-by-share basis among all such shares at the time outstanding.
The Board of Directors may fix a record date for the determination of holders
of shares of Series A Preferred Stock entitled to receive payment of a dividend
or distribution declared thereon, which record date shall be no more than 30
days prior to the date fixed for the payment thereof.

         Section 3.       Voting Rights.  The holders of shares of Series A
Preferred Stock shall have the following voting rights:

         (A)     Subject to the provision for adjustment hereinafter set forth,
each share of Series A Preferred Stock shall entitle the holders thereof to 100
votes on all matters submitted to a vote of the stockholders of the
corporation.  In the event the corporation shall at any time after the Rights
Declaration Date (i) declare any dividend on Common Stock payable in shares of
Common Stock, (ii) subdivide the outstanding Common Stock, or (iii) combine the
outstanding Common Stock into a smaller number of shares, then in each case the
number of votes per share to which holders of shares of Series A Preferred
Stock were entitled immediately prior to such event shall be adjusted by
multiplying such number by a fraction the numerator of which is the number of
shares of Common Stock outstanding immediately after such event and the
denominator of which is the number of shares of Common Stock that were
outstanding immediately prior to such event.





                                       3
   4
         (B)     Except as otherwise provided herein or by law, the holders of
shares of Series A Preferred Stock and the holders of shares of Common Stock
shall vote together as one class on all matters submitted to a vote of
stockholders of the corporation.

         (C)     Except as set forth herein, holders of Series A Preferred
Stock shall have no special voting rights and their consent shall not be
required (except to the extent they are entitled to vote with holders of Common
Sock as set forth herein) for taking any corporate action.

         Section 4.       Certain Restrictions.

         (A)     Whenever quarterly dividends or other dividends or
distributions payable on the Series A Preferred Stock as provided in Section 2
are in arrears, thereafter and until all accrued and unpaid dividends and
distributions, whether or not declared, on shares of Series A Preferred Stock
outstanding shall have been paid in full, the corporation shall not

                          (i) declare or pay dividends on, make any other
                 distribution on, or redeem or purchase or otherwise acquire
                 for consideration any shares of stock ranking junior (either
                 as to dividends or upon liquidation, dissolution or winding
                 up) to the Series A Preferred Stock;

                          (ii)    declare or pay dividends on or make any other
                 distributions on any shares of stock ranking on a parity
                 (either as to dividends or upon liquidation, dissolution or
                 winding up) with the Series A Preferred Stock, except
                 dividends paid ratably on the Series A Preferred Stock and all
                 such parity stock on which dividends are payable or in arrears
                 in proportion to the total amounts to which the holders of all
                 such shares are then entitled;

                          (iii)   redeem or purchase or otherwise acquire for
                 consideration shares of any stock ranking on a parity (either
                 as to dividends or upon liquidation, dissolution or winding
                 up) with the Series A Preferred Stock, provided that the
                 corporation may at any time redeem, purchase or otherwise
                 acquire shares of any such parity stock in exchange for shares
                 of any stock of the corporation ranking junior (either as to
                 dividends or upon dissolution, liquidation or winding up) to
                 the Series A Preferred Stock;

                          (iv)    purchase or otherwise acquire for
                 consideration any shares of Series A Preferred Stock, or any
                 shares of stock ranking on a parity with the Series A
                 Preferred Stock, except in accordance with a purchase offer
                 made in writing or by publication (as determined by the Board
                 of Directors) to all holders of such shares upon such terms as
                 the Board of Directors, after consideration of the respective
                 annual dividend rates and other relative rights and
                 preferences of the respective series and classes, shall
                 determine in good faith will result in fair and equitable
                 treatment among the respective series or classes.





                                       4
   5
         (B)     The corporation shall not permit any subsidiary of the
corporation to purchase or otherwise acquire for consideration any shares of
stock of the corporation unless the corporation could, under paragraph (A) of
this Section 4, purchase or otherwise acquire such shares at such time and in
such manner.

         Section 5.       Reacquired Shares.  Any shares of Series A Preferred
Stock purchased or otherwise acquired by the corporation in any manner
whatsoever shall be retired and cancelled promptly after the acquisition
thereof.  All such shares shall upon their cancellation become authorized but
unissued shares of Preferred Stock and may be reissued as part of a new series
of Preferred Stock to be created by resolution or resolutions of the Board of
Directors, subject to the conditions and restrictions on issuance set forth
herein.

         Section 6.       Liquidation, Dissolution or Winding Up.

         (A)     Upon any liquidation (voluntary or otherwise), dissolution or
winding up of the corporation, no distribution shall be made to the holders of
stock ranking junior (either as to dividends or upon liquidation, dissolution
or winding up) to the Series A Preferred Stock unless, prior thereto, the
holders of shares of Series A Preferred Stock shall have received $100 per
share, plus an amount equal to accrued and unpaid dividends and distributions
thereon, whether or not declared, to the date of such payment (the "Series A
Liquidation Preference").  Following the payment of the full amount of the
Series A Liquidation Preference, no additional distributions shall be made to
the holders of shares of Series A Preferred Stock unless, prior thereto, the
holders of shares of Common Stock shall have received an amount per share (the
"Common Adjustment") equal to the quotient obtained by dividing (i) the Series
A Liquidation Preference by (ii) 100 (as appropriately adjusted as set forth in
subparagraph C below to reflect such events as stock splits, stock dividends
and recapitalizations with respect to the Common Stock) (such number in clause
(ii), the "Adjustment Number").  Following the payment of the full amount of
the Series A Liquidation Preference and the Common Adjustment in respect of all
outstanding shares of Series A Preferred Stock and Common Stock, respectively,
holders of Series A Preferred Stock and holders of shares of Common Stock shall
receive their ratable and proportionate share of remaining assets to be
distributed in the ratio of the Adjustment Number to 1 with respect to such
Preferred Stock and Common Stock, on a per share basis, respectively.

         (B)     In the event, however, that there are not sufficient assets
available to permit payment in full of the Series A Liquidation Preference and
the liquidation preferences of all other series of Preferred Stock, if any
which rank on a parity with the Series A Preferred Stock, then such remaining
assets shall be distributed ratably to the holders of such parity shares in
proportion to their respective liquidation preferences.  In the event, however,
that there are not sufficient assets available to permit payment in full of the
Common Adjustment, then such remaining assets shall be distributed ratably to
the holders of Common Stock.

         (C)     In the event the corporation shall at any time after the
Rights Declaration Date (i) declare any dividend on Common Stock payable in
shares of Common Stock, (ii) subdivide the outstanding Common Stock, or (iii)
combine the outstanding Common Stock into a smaller number of shares, then in
each such case the Adjustment Number in effect immediately prior to such event
shall be adjusted by multiplying such Adjustment Number by a fraction the
numerator





                                       5
   6
of which is the number of shares of Common Stock outstanding immediately after
such event and the denominator of which is the number of shares of Common Stock
that were outstanding immediately prior to such event.

         Section 7.       Consolidation, Merger, etc.  In case the corporation
shall enter into any consolidation, merger, combination or other transaction in
which the shares of Common Stock are exchanged for or changed into other stock
or securities, cash and/or any other property, then in any such case the shares
of Series A Preferred Stock shall at the same time be similarly exchanged or
changed in an amount per share (subject to the provision for adjustment
hereinafter set forth) equal to 100 times the aggregate amount of stock,
securities, cash and/or any other property (payable in kind), as the case may
be, into which or for which each share of Common Stock is changed or exchanged.
In the event the corporation shall at any time after the Rights Declaration
Date (i) declare any dividend on Common Stock payable in shares of Common
Stock, (ii) subdivide the outstanding Common Stock, or (iii) combine the
outstanding Common Stock into a smaller number of shares, then in each such
case the amount set forth in the preceding sentence with respect to the
exchange or change of shares of Series A Preferred Stock shall be adjusted by
multiplying such amount by a fraction the numerator of which is the number of
shares of Common Stock outstanding immediately after such event and the
denominator of which is the number of shares of Common Stock that were
outstanding immediately prior to such event.

         Section 8.        No Redemption.  The shares of Series A Preferred
Stock shall not be redeemable.

         Section 9.       Ranking.  The Series A Preferred Stock shall rank
junior to all other series of the corporation's preferred stock, if any, as to
the payment of dividends and the distribution of assets, unless the terms of
any such series shall provide otherwise.

         Section 10.      Amendment.  The Certificate of Incorporation of the
corporation shall not be further amended in any manner which would materially
alter or change the powers, preferences or special rights of the Series A
Preferred Stock so as to affect them adversely without the affirmative vote of
the holders of a majority or more of the outstanding shares of Series A
Preferred Stock, voting separately as a class.

         Section 11.      Fractional Shares.  Series A Preferred Stock may be
issued in fractions of a share, which shall entitle the holder, in proportion
to such holder's fractional shares, to exercise voting rights, receive
dividends, participate in distributions and to have the benefit of all other
rights of holders of Series A Preferred Stock.

                                   ARTICLE VI
                          BOARD POWER REGARDING BYLAWS

         In furtherance and not in limitation of the powers conferred by
statute, the Board of Directors is expressly authorized to make, repeal, alter,

                             ELECTION OF DIRECTORS

         Elections of directors need not be by written ballot unless the Bylaws
of the corporation shall so provide.

                                  ARTICLE VIII
                        LIMITATION OF DIRECTOR LIABILITY

         To the fullest extent permitted by the General Corporation Law of the
State of Delaware as the same exists or may hereafter be amended, a director of
this corporation shall not be liable to the corporation or its stockholders for
monetary damages for breach of fiduciary duty as director.

                                   ARTICLE IX
                 NO ACTIONS BY WRITTEN CONSENT OF SHAREHOLDERS

         No action required to be taken or which may be taken at any annual or
special meeting of stockholders of the corporation may be taken without a
meeting, and the power of stockholders to consent in writing without a meeting
to the taking of any action is specifically denied.

                                   ARTICLE X
                                CORPORATE POWER

         The corporation reserves the right to amend, alter, change or repeal
any provision contained in this Certificate of Incorporation, in the manner now
or hereafter prescribed by statute, and all rights conferred on stockholders
herein are granted subject to this reservation.

                                   ARTICLE XI
                       CREDITOR COMPROMISE OR ARRANGEMENT

         Whenever a compromise or arrangement is proposed between this
corporation and its creditors or any class of them and/or between this
corporation and its stockholders or any class of them, any court of equitable
jurisdiction within the State of Delaware may, on the application in a summary
way of this corporation or of any creditor or stockholder thereof or on the
application of any receiver or receivers appointed for this corporation under
the provisions of Section 291 of Title 8 of the Delaware Code or on the
application of trustees in dissolution or of any receiver or receivers
appointed for this corporation under the provisions of Section 279 of Title 8
of the Delaware Code order a meeting of the creditors or class of creditors,
and/or of the stockholders or class of stockholders of this corporation, as the
case may be, to be summoned in such manner as the said court directs.  If a
majority in number representing three-fourths in value of the creditors or
class of creditors, and/or of the stockholders or class of stockholders of this
corporation, as the case may be, agree to any compromise or arrangement and to
any reorganization of this corporation as a consequence of such compromise or
arrangement, the said compromise or arrangement and the said reorganization
shall, if sanctioned by the court to which the said application has been made,
be binding on all the creditors or class of creditors, and/or on all the
stockholders or class of stockholders, of this corporation, as the case may be,
and also on this corporation.
