                 (v)       except for the "Permitted Title Exceptions" set

                           property are supplied with utilities and other

                 (viii)    except for the "Permitted Title Exceptions" set
                           forth in the Escrow Agreement, to the knowledge of
                           Company, there are no liens, restrictions or other
                           encumbrances against the title to the Real Property
                           which will be binding upon Motorola or the Real
                           Property after the Closing Date and which will
                           materially adversely affect the use or value of the
                           Real Property.

With respect to the representation and warranty set forth in Section 7.08(viii)
above, Motorola waives any right to proceed against Company to the extent any
nondisclosed matter is covered by the title insurance policy procured by
Company pursuant to the Escrow Agreement.

         7.08    Inventories.

         All inventories of raw materials and work-in-process related to the
Wafer Fab Operations to be included in the Acquisition Assets, which are
assigned a value in Schedule 2.01(b) attached hereto, consist only of items of
a quality and quantity usable or salable by the Company in the Ordinary Course
of Business.  All such inventory is merchantable and fit for the purpose for
which it was procured or manufactured, and none of which is slow-moving,
obsolete, damaged, or defective.  It is understood and agreed that in the event
that any of the wafers within the inventories covered by this Section 7.08 are
later designated by the Company to be scrap material, the provisions of the
Wafer Supply Agreement will govern the consequences of scrapping such material
and, as a result, any such event will not be deemed a breach of this Section
7.08.

         7.09    Commitments.

         To the best knowledge and belief (after due inquiry and investigation)
of the Company, except as disclosed in Schedule 7.09 attached hereto, all
contracts and agreements included in the Assumed Liabilities are valid,
binding, enforceable, fully assignable and in full force and effect and will
not expire prior to January 1, 1994 (except for such contracts and agreements
which will be renewed on substantially similar economic terms).  Neither the
Company nor, to the best knowledge of the Company, any other party to any such
contract or agreement is in default, or will be in default upon Closing Date,
under any such contract or agreement (including, but not limited to, any event
which would, with the giving of notice or the passage of time or both,
constitute an event of default).  True, correct and complete copies of all such
written contracts and agreements have been previously given to Motorola.  The
Company is not a party to any employment, consulting or similar agreement with
or for the benefit of any of its employees involved in the Wafer Fab
Operations.  The Company does not expect that any change is reasonably likely
to occur in the relationships of the Company with suppliers to its Wafer Fab
Operations which change would be materially adverse to the Wafer Fab Operations
(provided that this representation and warranty shall not include changes in
such relationships arising due to this transaction).

         7.10    Absence of Certain Changes.

         Since September 25, 1993 there has not been:

         (a)     any change in the nature of the Wafer Fab Operations, or
                 manner of conducting the Wafer Fab Operations which has had,
                 or may reasonably be expected to have, a material adverse
                 effect on the Wafer Fab Operations;

         (b)     any material damage, destruction or other casualty loss
                 (whether or not covered by insurance) affecting the
                 Acquisition Assets;

         (c)     any increase in the compensation payable or to become payable
                 by the Company to any Listed Employees or to agents directly
                 involved in the Wafer Fab Operations over the amount paid, at
                 September 25, 1993, other than normal merit increases,
                 increases which are not material and increases consented to by
                 Motorola in writing;

         (d)     any sale, lease, transfer or assignment of any of the
                 Acquisition Assets, tangible or intangible, other than
                 nonmaterial transfers (such as transfers of finished goods)
                 for a fair consideration in the Ordinary Course of Business;

         (e)     any material acceleration, termination, modification or
                 cancellation of any contract, lease, sublease, license, or
                 sublicense (or series of related contracts, leases, subleases,
                 licenses, and sublicenses) relating to the Wafer Fab
                 Operations or the Real Property to which the Company is a
                 party or by which it is bound;

         (f)     any delaying or postponing by the Company (beyond practice in
                 the Ordinary Course of Business) of the payment of accounts
                 payable and other liabilities related to the Wafer Fab
                 Operations;

         (g)     any loan to, or entry into any other transaction with, any of
                 the Listed Employees substantially involved in the Wafer Fab
                 Operations outside the Ordinary Course of Business;

         (h)     any entry into or commitment to enter into any employment
                 contract or collective bargaining agreement, written or oral,
                 with Listed Employees or modification of the terms of any such
                 existing contract or agreement;

                 Employees, or any modification or termination of any such
                 existing plan, contract or commitment; or

         (j)     any commitment to do any of the foregoing.

         7.11    Intellectual Property.

         (a)     Pursuant to law, the Company owns or has the right to use
                 under license, sublicense, agreement, or permission all
                 Relevant Intellectual Property.  As used herein, "Relevant
                 Intellectual Property" means only the copyrighted works, mask

                 Intellectual Property is hereby licensed to Motorola by the
                 Company as otherwise will be available for use by Motorola on
                 identical terms and conditions to those under which each item
                 of Relevant Intellectual Property is used or is available for
                 use by the Company.

         (b)     With respect to each such item of Relevant Intellectual
                 Property:

                           of time would constitute a breach or default or
                           permit termination, modification, or acceleration
                           thereunder;

                           the Company s knowledge, is threatened which
                           challenges the legality, validity, or enforceability
                           of the underlying item of Relevant Intellectual
                           Property.

                 including any amendment thereof.


       (b)       The Company has withheld and paid all Taxes required to have
                 been withheld and paid in connection with amounts paid

                 relating to a matter covered by any such representation or
                 warranty, whether or not such claim is valid.



December 16, 1993                                                       Page 32

         10.03     Matters Involving Third Parties.

         If any third party shall notify any party hereto (the "Indemnified
Party") with respect to any matter which may give rise to a claim for
indemnification against any other party (the "Indemnifying Party") under this
Section, then the Indemnified party shall notify each Indemnifying Party
thereof promptly; provided, however, that no delay on the part of the
Indemnified Party in notifying any Indemnifying Party shall relieve the
Indemnifying Party from any liability or obligation hereunder unless (and then
solely to the extent) the Indemnifying Party thereby is damaged.

         In the event any Indemnifying Party notifies the Indemnified Party
within 15 days after the Indemnified Party has given notice of the matter
giving rise to the claim that the Indemnifying Party is assuming the defense
thereof, (a) the Indemnifying Party will defend the Indemnified Party against
the matter with counsel of the Indemnifying Party s choice reasonably
satisfactory to the Indemnified Party, (b) the Indemnified Party may retain
separate co-counsel at its sole cost and expense (except that the Indemnifying
Party will be responsible for the fees and expenses of the separate co-counsel
to the extent the Indemnified Party reasonably concludes that the counsel the
Indemnifying Party has selected has a conflict of interest), (c) the
Indemnified Party will not consent to the entry of any judgment or enter into
any settlement with respect to the matter without the written consent of the
Indemnifying Party, such consent not to be unreasonably withheld), and (d) the
Indemnifying Party will not consent to the entry of any judgment with respect
to the matter, or enter into any settlement which does not include a provision
whereby the plaintiff or claimant in the matter releases the Indemnified Party
from all liability with respect thereto, without the written consent of the
Indemnified Party such consent not to be unreasonably withheld.

         However, in the event that the Indemnifying Party does not notify the
Indemnified Party with 15 days after receipt of notice from the Indemnified
Party, that the Indemnifying Party will be assuming the defense thereof, the
Indemnified Party may defend against, or enter into any settlement with respect
to, the matter in any manner it deems appropriate.

         10.04     Other Indemnification Provision.

         The foregoing indemnification provisions are in addition to, and not
in derogation of, any statutory or common law remedy any party may have for
breach of representation, warranty, or covenant.



December 16, 1993                                                       Page 33

         10.05     Tax Indemnification Procedure.

         If any Tax arises out of the Wafer Fab Operations or the Acquisition
Assets before the Closing Date is assessed or claimed on or after such date by
a taxing authority, Motorola shall notify the Company and it will take over the
defense of each such tax claim as well as the liability for any settlement,
penalty, interest or tax due.  Motorola will take such action as is necessary
to cooperate in any proceedings with respect to any such tax or proposed tax.

         If any Sales Tax payment arising out of Motorola s purchase of the
Acquisition Assets is challenged by a taxing authority, Motorola and the
Company shall mutually agree on the defense of such claim and split the cost of
such defense equally.  Any additional tax, penalty or interest shall be split
equally.  Any tax refund shall likewise be split equally.


         11.     Miscellaneous.

         11.01     Survival.

         With the exception of (i) the representations and warranties with
respect to the condition of certain Acquisition Assets in Sections 7.07(a) and
7.08 hereof, which shall survive the Closing Date for one (1) year, (ii) any
representation and warranty covering Taxes which shall survive until expiration
of applicable statute(s) of limitation and (iii) the license and other rights
granted to Motorola pursuant to Section 7.11 hereof which shall survive the
Closing Date forever, all of the other representations and warranties of the
parties contained in Sections 7 and 8 of this Agreement shall survive the
Closing Date hereunder for five (5) years.  All of the covenants and
indemnities of the parties contained in this Agreement shall survive the
Closing Date forever.

         11.02     Press Releases and Announcements.

         No party shall issue any press release or announcement relating to the
subject matter of this Agreement prior to the Closing Date without the prior
written approval of the other parties; provided, however, that any party may
make any public disclosure it believes in good faith is required by law or
regulation (in which case the disclosing party will advise the other parties
prior to making the disclosure).

         11.03     No Third Party Beneficiaries.

         This Agreement shall not confer any rights or remedies upon any person
other than the parties and their respective successors and permitted assigns.

         11.04     Entire Agreement.

         This Agreement (including the documents referred to herein)
constitutes the entire agreement between the parties and supersedes any prior
understandings, agreements, or representations by or between the parties,
written or oral, that may have related in any way to the subject matter hereof.

         11.05     Succession and Assignment.

         This Agreement shall be binding upon and inure to the benefit of the
parties named herein and their respective successors and permitted assigns.  No
party may assign either this Agreement or any of its rights, interests, or
obligations hereunder without the prior written approval of the other party;
provided, however, that Motorola may (i) assign any or all of its rights and
interests hereunder to one or more of its Subsidiaries and (ii) designate one
or more of its Subsidiaries to perform its obligations hereunder (in any or all
of which Motorola nonetheless shall remain liable and responsible for the
performance of all of its obligations hereunder).

         11.06     Counterparts.

         This Agreement may be executed in one or more counterparts, each of
which shall be deemed an original but all of which together will constitute one
and the same instrument.

         11.07     Headings.

         The section headings contained in this Agreement are inserted for
convenience only and shall not affect in any way the meaning or interpretation
of this Agreement.

         11.08     Notices.

         All notices, requests, demands, claims, and other communications
hereunder will be in writing.  Any notice, request, demand, claim, or other
communication hereunder shall be deemed duly given if (and then two business
days after) it is sent by registered or certified mail, return receipt
requested, postage prepaid, and addressed to the intended recipient as set
forth below:

         Any party may give any notice, request, demand, claim, or other
communication hereunder using any other means (including personal delivery,
expedited courier, messenger service, telecopy, telex, ordinary mail, or
electronic mail), but no such notice, request, demand, claim, or other
communication shall be deemed to have been duly given unless and until it
actually is received by the individual for whom it is intended.  Any party may
change the address to which notices, requests, demands, claims, and other
communications hereunder are to be delivered by giving the other party notice
in the manner herein set forth.

         11.09     Governing Law.

         This Agreement shall be governed by and construed in accordance with
the internal laws (and not the law of conflicts) of the State of California.

         11.10     Amendments and Waivers.

         No amendment of any provision of this Agreement shall be valid unless
the same shall be in writing and signed by the Company and Motorola.  No waiver
by any party of any default, misrepresentation, or breach of warranty or
covenant hereunder, whether intentional or not, shall be deemed to extend to
any prior or subsequent default, misrepresentation, or breach of warranty or
covenant hereunder or affect in any way any rights arising by virtue of any
prior or subsequent such occurrence.

         11.11     Severability.

         Any term or provision of this Agreement that is invalid or
unenforceable in any situation in any jurisdiction shall not affect the
validity or enforceability of the remaining terms and provisions hereof or the
validity or enforceability of the offending term or provision in any other
situation or in any other jurisdiction.  If the final judgment of a court of
competent jurisdiction declares that any term or provision hereof is invalid or
unenforceable, the parties agree that the court making the determination of
invalidity or unenforceability shall have the power to reduce the scope,
duration, or area of the term or provision, to delete specific words or
phrases, or to replace any invalid or

unenforceable term or provision with a term or provision that is valid
and enforceable and that comes closest to expressing the intention of the
invalid or unenforceable term or provision, and this Agreement shall be
enforceable as so modified after the expiration of the time within which the
judgment may be appealed.

         11.12     Construction.

         The language used in this Agreement will be deemed to be the language
chosen by the parties to express their mutual intent, and no rule of strict
construction shall be applied against any party.  Any reference to any federal,
state, local, or foreign statute or law shall be deemed also to refer to all
rules and regulations promulgated thereunder, unless the context requires
otherwise.  Nothing in the Schedules shall be deemed adequate to disclose an
exception to a representation or warranty made herein unless the Schedules
identify the exception with reasonable particularity and describes the relevant
facts in reasonable detail.  The parties intend that each representation,
warranty, and covenant contained herein shall have independent significance.
If any party has breached any representation, warranty, or covenant contained
herein in any respect, the fact that there exists another representation,
warranty, or covenant relating to the same subject matter (regardless of the
relative levels of specificity) which the party has not breached shall not
detract from or mitigate the fact that the party is in breach of the first
representation, warranty, or covenant.

         11.13     Incorporation of Exhibits and Schedule.

         The Exhibits and Schedules identified in this Agreement are
incorporated herein by reference and made a part hereof.

         11.14     Specific Performance.

         Each of the parties acknowledges and agrees that the other parties
would be damaged irreparably in the event any of the provisions of this
Agreement are not performed in accordance with their specific terms or
otherwise are breached.  Accordingly, each of the parties agrees that the other
parties shall be entitled to an injunction or injunctions to prevent breaches
of the provisions of this Agreement and to enforce specifically this Agreement
and the terms and provisions hereof in any action instituted in any court of
the United States or any state thereof having jurisdiction over the parties and
the matter (subject to the provisions set forth below), in addition to any
other remedy to which it may be entitled, at law or in equity.

         11.15     Alternative Dispute Resolution.

         The parties will attempt to settle any claim or controversy arising
out of this Agreement through consultation and negotiation in good faith and in
a spirit of mutual cooperation.  If those attempts fail, then such dispute will
be mediated by a mutually-


December 16, 1993                                                       Page 37
Revision 7



   38
acceptable mediator to be chosen by the parties within fifteen (15)
business days after written notice by one of the parties demanding mediation. 
Neither the Company nor Motorola may unreasonably withhold consent to the
selection of the mediator.  By mutual agreement, however, the Company and
Motorola may postpone mediation until the Company and Motorola have each
completed some specified but limited discovery regarding the dispute.  The
parties may also mutually agree to replace mediation with some other form of
alternative dispute resolution ("ADR"), such as neutral fact-finding or a
mini-trial.

         Any dispute which the parties cannot resolve through negotiation,
mediation or another form of ADR within forty-five (45) days of the date of the
initial demand for ADR by one of the parties may be submitted to any federal or
state court of competent jurisdiction located in the State of California for
resolution.  The Company and Motorola agree to waive any objection to personal
jurisdiction or venue in any forum located in the State of California.  The use
of any ADR procedures will not be construed under the doctrine of laches,
waiver or estoppel to affect adversely the rights of any party.  Nothing in
this Section 11.15 will prevent any party from resorting to judicial
proceedings if (i) good faith efforts to resolve the dispute under these
procedures have been unsuccessful, or (ii) interim relief from a court is
necessary to prevent serious and irreparable injury to such party.

         11.16     Mutual Release.

         Motorola releases the Company and the Company releases Motorola from
every claim of infringement of every patent (whether a U.S. patent or
otherwise) for any acts carried out anywhere in the world at any time on or
before the Closing Date.

         12.01     Further Assistance.

         From and after the Closing Date, upon the request of Motorola, the
Company shall execute, acknowledge and deliver to Motorola (or cause to be
executed, acknowledged and delivered by others) all such further bills of sale,
assignments, transfers, conveyances, and other documents, in a form reasonably
satisfactory to Motorola, as may be required to convey, transfer and deliver to
Motorola, and protect Motorola's right, title and interest in the Acquisition
Assets, and as otherwise may be

appropriate to carry out the transactions contemplated by this Agreement.

         12.02     Regulatory Filings.

         Each of the parties hereto will furnish to the other parties hereto
such necessary information and reasonable assistance as such other parties may
reasonably request in connection with its preparation of necessary filings or
submissions to any governmental agency.

         12.03     [intentionally omitted]

         12.04     Litigation and IRS Support.

         In the event and for so long as any party actively is contesting or
defending against any charge, complaint, action, suit, proceeding, hearing,
investigation, claim, or demand in connection with (i) any transaction
contemplated under the agreement or (ii) any fact, situation, circumstance,
status, condition, activity, practice, plan, occurrence, event, incident,
action, failure to act, or transaction on or prior to the Closing Date
involving the Company, each of the other parties will cooperate with the
contesting or defending party and his or its counsel in the contest or defense,
make available his or its personnel, and provide such testimony and access to
his or its books and records as shall be necessary in connection with the
contest or defense, all at the sole cost and expense of the contesting or
defending party (unless the contesting or defending party is entitled to
indemnification therefor).

Agreement to be signed by their respective corporate seals to be affixed

Dear Rick:
           Reference is made to the Asset Purchase Agreement dated as of
December 16, 1993 (the "Agreement") by and between Motorola Inc.  ("Motorola")
and Western Digital Corporation (the "Company").  As used herein, the terms
"Closing" and "Closing Date" shall have the meanings ascribed to them in the
Agreement.  In consideration of the mutual promises contained herein, Motorola
and the Company hereby agree as follows:

           1.      Section 2.01(b) of the Agreement provides for calculation of
the amount to be paid by Motorola to the Company for raw material and
work-in-process inventories based on Schedule 2.01(b) to the Agreement, to be
updated as of 4:00 p.m. on the Closing Date.  The parties have agreed to use
the dollar amount set forth in such Schedule 2.01(b) ($6,735,267.65) for
purposes of the Closing and hereby agree to adjust that amount to reflect the
final raw material and work-in-process schedule which will be prepared in a
manner consistent with such Schedule 2.01(b) and will be available after the
Closing.  If the adjusted amount is higher than the amount used for Closing,
Motorola will pay the additional amount to the Company in two equal
installments at the time of payments on the Buyer Note.  If the adjusted amount
is lower, then the difference will be offset against the two installments due
under the Buyer Note.

           2.      Sections 3.01 and 4.07 of the Agreement, as well as other
sections of the Agreement, refer to "Listed Employees" as reflected in Schedule
3.01 to the Agreement.  Such Schedule 3.01 has been prepared as of the most
recent

practicable time prior to the Closing; however, the parties are
continuing the process of determining whether certain additional Company
employees (approximately 15 or less in number) will become "Listed Employees"
subject to such additional employees qualifying under Motorola's employment
policies.  The persons to be added to the list of "Listed Employees" will be
designated in writing by Motorola in its discretion prior to January 1, 1994.

        3.  Schedule 1.03 (Excluded Assets) to the Agreement contains,
among other things, a schedule of excluded supplies which will need to be
updated as of 4:00 p.m. on the Closing Date.  Since this update will not be
available until after the Closing, the parties agree to complete such update in
a manner consistent with the schedule of excluded supplies which is included in
such Schedule 1.03 as of the Closing.

        4.   The allocation referred to in Section 2.02 of the Agreement
will be completed and agreed to by the parties by January 30, 1994.

                   
                                Very truly yours,
                                Western Digital Corporation
