Delivery of Purchase Notice and Debentures. This Purchase Notice can be used only if Debentures are to be delivered with it to the Paying Agent or a surrender of Debentures is being made concurrently by book-entry transfer to the Paying Agent's account at DTC.

The term "agent's message" means a message transmitted to DTC and received by the Paying Agent and forming a part of a book-entry transfer, that states that DTC has received an express acknowledgement that the undersigned agrees to be bound by this Purchase Notice and that the Company may enforce this Purchase Notice against the undersigned. Delivery of documents to DTC, the Company or Western Digital Corporation does not constitute delivery to the Paying Agent. The method of delivery of all documents, including Debentures, this Purchase Notice and any other required documents, is at the election and risk of the surrendering Holder(s). If delivery is by mail, registered mail with return receipt requested, properly insured, is recommended. The Company will not accept any alternative, conditional or contingent surrenders. Each surrendering Holder, by execution of this Purchase Notice, waives any right to receive any notice of the acceptance of his or her surrender. 2. Guarantee of Signatures. No signature guarantee is required if either: (a) this Purchase Notice is signed by the registered Holder(s) of the Debentures (which term, for purposes of this Purchase Notice, includes any participant in DTC whose name appears on a security position listing as the Holder of such Debentures) surrendered with the Purchase Notice, unless such Holder has completed the box entitled "Special Issuance Instructions" and/or "Special Delivery Instructions" above; or (b) the Debentures surrendered with this Purchase Notice are surrendered for the account of an eligible guarantor institution, as defined in Rule 17Ad-15 under the Exchange Act (each, an "Eligible Institution"). In all other cases an Eligible Institution must guarantee the signatures on this Purchase Notice. See Instruction 5. 3. Inadequate Space. If the space provided in the box captioned "Description of Debentures Being Surrendered for Purchase" is inadequate, the Debenture certificate numbers, 8 the principal amount represented by the Debentures and the principal amount surrendered should be listed on a separate signed schedule and attached to this Purchase Notice. 4. Partial Surrenders and Unpurchased Debentures. (Not applicable to Holders who surrender by book-entry transfer.)

The Company also reserves the absolute right to waive any defect or irregularity in the surrender of any particular Debentures. No surrender of Debentures will be deemed to be properly made until all defects and irregularities have been cured or waived. Unless waived, any defects or irregularities in connection with surrenders must be cured within such time as the Company shall determine.

This Purchase Notice and related documents cannot be processed until the procedures for replacing mutilated, lost, stolen or destroyed certificates have been followed. 9. Questions and Requests for Assistance and Additional Copies. Questions and requests for assistance may be directed to Steven M. Slavin, the Company's Vice President, Taxes and Treasurer, at (949) 672-7826, and additional copies of the Company Notice and this Purchase Notice may also be obtained from the Paying Agent at its addresses set forth above or the Company's Investor Relations at (800) 695-6399. 10. Withdrawal Rights. You may withdraw previously surrendered Debentures at any time until 5:00 p.m., New York City time, on February 18, 2003. You may also withdraw surrendered Debentures at any time after the expiration of 40 business days from the date of the Company Notice if your Debentures have not yet been accepted for payment. See Section 4 of the Company Notice for a more detailed description of withdrawal rights. 11. Transfer Taxes. Except as set forth in this Instruction 11, the Company will pay or cause to be paid any transfer taxes with respect to the transfer and purchase of Debentures 10 to it, or to its order, pursuant to the Company Notice. If payment of the Purchase Price is to be made to, or if Debentures not surrendered or purchased are to be registered in the name of, any persons other than the registered Holders, or if surrendered Debentures are registered in the name of any persons other than the persons signing this Purchase Notice, the amount of any transfer taxes (whether imposed on the registered Holder(s) or such other person) payable on account of the transfer to such other person will be deducted from the Purchase Price unless satisfactory evidence of the payment of such taxes or an exemption therefrom is submitted. 12. Taxpayer Identification Number. Each Holder surrendering Debentures is required to provide the Paying Agent with the Holder's correct taxpayer identification number ("TIN"), generally the Holder's Social Security or federal employer identification number, and certain other information, on Substitute Form W-9, which is provided below, or, alternatively, to establish another basis for exemption from backup withholding. Additionally, a Holder must cross out item (2) in the Certification box on Substitute Form W-9 if the Holder is subject to backup withholding. Failure to provide the information on the form may subject the Holder to a $50 penalty imposed by the Internal Revenue Service and 30% federal income tax backup withholding on the payments made to the Holder or to the payee with respect to Debentures purchased pursuant to the Company Notice. The box in Part 3 of the form should be checked if the Holder has not been issued a TIN and has applied for a TIN or intends to apply for a TIN within 60 days, thereafter the Paying Agent will withhold 30% on all payments of the Purchase Price until a TIN is provided to the Paying Agent. If this applies, the Holder must complete the "Certificate of Awaiting Taxpayer Identification Number" below. Certain Holders (including, among others, all corporations and certain foreign persons) are not subject to these backup withholding and reporting requirements. Exempt Holders should indicate their exempt status on the Substitute Form W-9. A foreign person may qualify as an exempt recipient by submitting to the Paying Agent a properly completed Internal Revenue Service Form W-8BEN, signed under penalties of perjury, attesting to that Holder's exempt status. A Form W-8BEN can be obtained from the Paying Agent. See the enclosed "Guidelines for Certification of Taxpayer Identification Number on Substitute Form W-9" for additional instructions. If backup withholding applies, the Paying Agent is required to withhold 30% of any Purchase Price payments made to the Holder or to the payee. Backup withholding is not an additional federal income tax. Rather, the federal income tax liability of persons subject to backup withholding will be reduced by the amount of tax withheld. If withholding results in an overpayment of taxes, a refund may be obtained by filing a tax return with the Internal Revenue Service. The Paying Agent cannot refund amounts withheld by reason of backup withholding. PURPOSE OF SUBSTITUTE FORM W-9 To prevent backup withholding on Purchase Price payments made with respect to the Debentures surrendered pursuant to the Company Notice, the Holder is required to provide the Paying Agent with: - the Holder's correct TIN (or, if applicable, the TIN of the payee) by completing the "Substitute Form W-9" below, certifying that the TIN provided on Substitute Form 11 W-9 is correct (or that such Holder is awaiting a TIN), that the Holder is a U.S. person (including a U.S. resident alien), and that: o such Holder is exempt from backup withholding, o the Holder has not been notified by the Internal Revenue Service that the Holder is subject to backup withholding as a result of failure to report all interest or dividends, or o the Internal Revenue Service has notified the Holder that the Holder is no longer subject to backup withholding; and - if applicable, an adequate basis for exemption. 12 WHAT NUMBER TO GIVE THE PAYING AGENT The Holder is required to give the Paying Agent his or her TIN (e.g., Social Security Number or Employer Identification Number). If the Debentures are held in more than one name or are held not in the name of the actual owner, consult the enclosed "Guidelines for Certification of Taxpayer Identification Number on Substitute Form W-9" for additional guidance on which number to report.
