Each determination by the Agent of an interest rate hereunder shall be conclusive and binding for all purposes, absent manifest error.

(c) Whenever any payment hereunder or under the Notes shall be stated to be due on a day other than a Business Day, such payment shall be made on the next succeeding Business Day, and such extension of time shall in such case be included in the computation of payment of interest, fee or commission, as the case may be; provided, however, that, if such extension would cause payment of interest on or principal of Eurodollar Rate Advances to be made in the next following calendar month, such payment shall be made on the next preceding Business Day.

(d) Unless the Agent shall have received notice from the Borrower prior to the date on which any payment is due to the Lenders hereunder that the Borrower will not make such payment in full, the Agent may assume that the Borrower has made such payment in full to the Agent on such date and the Agent may, in reliance upon such assumption, cause to be distributed to each Lender on such due date an amount equal to the amount then due such Lender. If and to the extent the Borrower shall not have so made such payment in full to the Agent, each Lender shall repay to the Agent forthwith on demand such amount distributed to such Lender together with interest thereon, for each day from the date such amount is distributed to such Lender until the date such Lender repays such amount to the Agent, at the Federal Funds Rate.

SECTION 2.14 Taxes. (a) Any and all payments by the Borrower to or for the account of any Lender or the Agent hereunder or under the Notes or any other documents to be delivered hereunder shall be made, in accordance with Section 2.13 or the applicable provisions of such other documents, free and clear of and without deduction for any and all present or future taxes, levies, imposts, deductions, charges or withholdings, and all liabilities with respect thereto, excluding, in the case of each Lender and the Agent or any other recipient of any payment made by or on account of any obligation of the Borrower hereunder, in each case inclusive of all liabilities with respect thereof, (i) all taxes imposed on or measured by its overall net income (however denominated), franchise taxes imposed on it in lieu of net income taxes and branch profits taxes imposed on it (A) by the jurisdiction (or any political subdivision thereof) under the laws of which such Lender or the Agent (as the case may be) is organized or has its principal place of business, (B) by a jurisdiction solely as a result of a present or former connection between the Agent or such Lender and such jurisdiction (other than any such connection arising from such recipient having executed, delivered or performed its obligations or received a

payment under, or enforced, or otherwise with respect to, any of the Loan Documents), or (C) in the case of each Lender, by the jurisdiction of such Lender’s Applicable Lending Office or any political subdivision thereof, (ii) any withholding or backup withholding tax that (A) is imposed under a law in effect at the time such Lender becomes a party hereto or otherwise acquires an interest herein (or designates a new lending office) or (B) is attributable to such Lender’s failure (or unreasonable delay) to comply with Section 2.14(e) or Section 2.14(f), except to the extent that such Lender (or its assignor, if any) was otherwise entitled, at the time of designation of a new lending office (or assignment), to receive additional amounts from the Borrower with respect to such withholding tax pursuant to this Section 2.14(a), and (iii) any tax that results from a recipient’s gross negligence or willful misconduct (all such non-excluded taxes, levies, imposts, deductions, charges, withholdings and liabilities in respect of payments hereunder or under the Notes being hereinafter referred to as “Taxes”). If the Borrower shall be required by law to deduct any Taxes from or in respect of any sum payable hereunder or under any Note or any other documents to be delivered hereunder to any Lender or the Agent, (i) the sum payable shall be increased as may be necessary so that after making all required deductions (including deductions applicable to additional sums payable under this Section 2.14) such Lender or the Agent (as the case may be) receives an amount equal to the sum it would have received had no such deductions been made, (ii) the Borrower shall make such deductions and (iii) the Borrower shall pay the full amount deducted to the relevant taxation authority or other authority in accordance with applicable law.

(b) In addition, the Borrower shall pay any present or future stamp or documentary taxes or any other excise or property taxes, charges or similar levies that arise from any payment made hereunder or under the Notes or any other documents to be delivered hereunder or from the execution, delivery or registration of, performing under, or otherwise with respect to, this Agreement or the Notes or any other documents to be delivered hereunder (hereinafter referred to as “Other Taxes”).

(c) The Borrower shall indemnify each Lender and the Agent for and hold it harmless against the full amount of Taxes or Other Taxes (including, without limitation, taxes of any kind imposed or asserted by any jurisdiction on amounts payable under this Section 2.14) imposed on or paid by such Lender or the Agent (as the case may be) and any liability (including penalties, interest and expenses) arising therefrom or with respect thereto. A certificate of the Agent or a Lender setting forth in reasonable detail the amount or amounts necessary to compensate the Agent or such Lender shall be delivered to the Borrower by the applicable Lender (with a copy to the Agent), or by the Agent on its own behalf or on behalf of the applicable Lender. This indemnification shall be made within 30 days from the date such Lender or the Agent (as the case may be) delivers such certificate therefor.

(d) Within 30 days after the date of any payment of Taxes, the Borrower shall furnish to the Agent, at its address referred to in Section 8.02, the original or a certified copy of a receipt evidencing such payment to the extent such a receipt is issued therefor, or other written proof of payment thereof that is reasonably satisfactory to the Agent. For purposes of subsection (e) and subsection (f), the terms “United States” and “United States person” shall have the meanings specified in Section 7701 of the Internal Revenue Code.

(e) Each Lender organized under the laws of a jurisdiction outside the United States, on or prior to the date of its execution and delivery of this Agreement in the case of each Initial Lender and on the date of the Assignment and Acceptance pursuant to which it becomes a Lender in the case of each other Lender, and from time to time thereafter as reasonably requested in writing by the Borrower (but only so long as such Lender remains lawfully able to do so), shall provide each of the Agent and the Borrower with two original Internal Revenue Service Forms W-8BEN or W-8ECI, as appropriate, or any successor or other form prescribed by the Internal Revenue Service, certifying that such Lender is exempt from or entitled to a reduced rate of United States withholding tax on payments pursuant to this Agreement or the Notes. If the form provided by a Lender at the time such Lender first becomes a party to this Agreement indicates a United States interest withholding tax rate in excess of zero, withholding tax at such rate shall be considered excluded from Taxes unless and until such Lender provides the appropriate forms certifying that a lesser rate applies, whereupon withholding tax at such lesser rate only shall be considered excluded from Taxes for periods governed by such form. If any form or document referred to in this subsection (e) requires the disclosure of information, other than information necessary to compute the tax payable and information required on the date hereof by Internal Revenue Service Form W-8BEN or W-8ECI, that the Lender reasonably considers to be confidential, the Lender shall give notice thereof to the Borrower and shall not be obligated to include in such form or document such confidential information.

(f) Any Lender that is a United States person and has not otherwise established to the reasonable satisfaction of the Borrower and the Agent that it is an exempt recipient (as defined in section 6049(b)(4) of the Internal Revenue Code and the United States Treasury Regulations thereunder) shall deliver to the Borrower and the Agent (in such number of copies as shall be reasonably requested by the recipient) on or prior to the date on which such Lender becomes a Lender under this Agreement (and from time to time thereafter upon the request of the Borrower or the Agent or as otherwise prescribed by applicable law, but only if such Lender is legally entitled to do so), duly executed and properly completed copies of Internal Revenue Service Form W-9.

(g) Any Lender claiming any additional amounts payable pursuant to this Section 2.14 agrees to use reasonable efforts (consistent with its internal policy and legal and regulatory restrictions) to change the jurisdiction of its Eurodollar Lending Office if the making of such a change would avoid the need for, or materially reduce the amount of, any such additional amounts that may thereafter accrue and would not, in the reasonable judgment of such Lender, be otherwise disadvantageous to such Lender.

(h) If the Agent or a Lender determines, in its good faith discretion, that it has received a refund of any Taxes or Other Taxes as to which it has been indemnified by the Borrower or with respect to which the Borrower has paid additional amounts pursuant to this Section, it shall pay to the Borrower an amount equal to such refund (but only to the extent of indemnity payments made, or additional amounts paid, by the Borrower under this Section with respect to Taxes or Other Taxes giving rise to such refund), net of all out-of-pocket expenses of the Agent or such Lender and without interest (other than any interest paid by the relevant governmental authority with respect to such refund); provided that the Borrower, upon the request of the Agent or such Lender, agrees to repay the amount paid over to the Borrower (plus any penalties, interest or other charges imposed by the relevant governmental authority) to the

Agent or such Lender in the event the Agent or such Lender is required to repay such refund to such governmental authority. This paragraph shall not be construed to require the Agent or any Lender to make available its tax returns (or any other information relating to its taxes that it deems confidential) to the Borrower or any other person.

SECTION 2.15 Sharing of Payments, Etc. If any Lender shall obtain any payment (whether voluntary, involuntary, through the exercise of any right of set-off, or otherwise) on account of the Advances owing to it (other than (x) pursuant to Section 2.11, 2.14 or 8.04(c)) in excess of its ratable share of payments on account of the Advances obtained by all the Lenders, such Lender shall forthwith purchase from the other Lenders such participations in the Advances owing to them as shall be necessary to cause such purchasing Lender to share the excess payment ratably with each of them; provided, however, that if all or any portion of such excess payment is thereafter recovered from such purchasing Lender, such purchase from each Lender shall be rescinded and such Lender shall repay to the purchasing Lender the purchase price to the extent of such recovery together with an amount equal to such Lender’s ratable share (according to the proportion of (i) the amount of such Lender’s required repayment to (ii) the total amount so recovered from the purchasing Lender) of any interest or other amount paid or payable by the purchasing Lender in respect of the total amount so recovered. The Borrower agrees that any Lender so purchasing a participation from another Lender pursuant to this Section 2.15 may, to the fullest extent permitted by law, exercise all its rights of payment (including the right of set-off) with respect to such participation as fully as if such Lender were the direct creditor of the Borrower in the amount of such participation.

SECTION 2.16 Evidence of Debt. (a) Each Lender shall maintain in accordance with its usual practice an account or accounts evidencing the indebtedness of the Borrower to such Lender resulting from each Advance owing to such Lender from time to time, including the amounts of principal and interest payable and paid to such Lender from time to time hereunder in respect of Advances. The Borrower agrees that upon notice by any Lender to the Borrower (with a copy of such notice to the Agent) to the effect that a Note is required or appropriate in order for such Lender to evidence (whether for purposes of pledge, enforcement or otherwise) the Advances owing to, or to be made by, such Lender, the Borrower shall promptly execute and deliver to such Lender a Note payable to the order of such Lender in a principal amount equal to the Commitment of such Lender.

(b) The Register maintained by the Agent pursuant to Section 8.07(d) shall include a control account, and a subsidiary account for each Lender, in which accounts (taken together) shall be recorded (i) the date and amount of each Borrowing made hereunder, the Type of Advances comprising such Borrowing and, if appropriate, the Interest Period applicable thereto, (ii) the terms of each Assignment and Acceptance delivered to and accepted by it, (iii) the amount of any principal or interest due and payable or to become due and payable from the Borrower to each Lender hereunder and (iv) the amount of any sum received by the Agent from the Borrower hereunder and each Lender’s share thereof.

(c) Entries made in good faith by the Agent in the Register pursuant to subsection (b) above, and by each Lender in its account or accounts pursuant to subsection (a) above, shall be prima facie evidence of the amount of principal and interest due and payable or to become due and payable from the Borrower to, in the case of the Register, each Lender and, in

the case of such account or accounts, such Lender, under this Agreement, absent manifest error; provided, however, that the failure of the Agent or such Lender to make an entry, or any finding that an entry is incorrect, in the Register or such account or accounts shall not limit or otherwise affect the obligations of the Borrower under this Agreement.

SECTION 2.17 Use of Proceeds. The proceeds of the Advances (a) shall be contributed to State M Corporation and used by State M Corporation to fund the Tender Offer and the Acquisition (including paying fees, commissions and expenses in connection with the Tender Offer and the Acquisition) and (b) may be used to repurchase the Komag Subordinated Notes.

(c) Maintenance of Insurance. Maintain, and cause each of its Subsidiaries to maintain, insurance with responsible and reputable insurance companies or associations in such amounts and covering such risks as is usually carried by companies engaged in similar businesses and owning similar properties in the same general areas in which the Borrower or such Subsidiary operates; provided, however, that the Borrower and its Subsidiaries may self-insure to the same extent as other companies engaged in similar businesses and owning similar properties in the same general areas in which the Borrower or such Subsidiary operates and to the extent consistent with prudent business practice.

(h) Transactions with Affiliates. Conduct, and cause each of its Subsidiaries to conduct, all material transactions otherwise permitted under this Agreement with any of their Affiliates on terms that are fair and reasonable and no less favorable to the Borrower or such Subsidiary than it would obtain in a comparable arm’s-length transaction with a Person not an Affiliate, other than (i) transactions between the Borrower and its Subsidiaries, or between two or more Subsidiaries, (ii) compensation arrangements for directors or executive officers approved by the Board of Directors or the compensation committee of the board of directors and (iii) transactions incurred in the ordinary course of business with Persons that have directors who are also directors or executive officers of the Borrower.

Each Lender hereby appoints and authorizes the Agent to take such action as agent on its behalf and to exercise such powers and discretion under this Agreement as are delegated to the Agent by the terms hereof, together with such powers and discretion as are reasonably incidental thereto. As to any matters not expressly provided for by this Agreement (including, without limitation, enforcement or collection of the Notes), the Agent shall not be required to exercise any discretion or take any action, but shall be required to act or to refrain from acting (and shall be fully protected in so acting or refraining from acting) upon the instructions of the Required Lenders, and such instructions shall be binding upon all Lenders and all holders of Notes; provided, however, that the Agent shall not be required to take any action that exposes the Agent to personal liability or that is contrary to this Agreement or applicable law. The Agent agrees to give to each Lender prompt notice of each notice given to it by the Borrower pursuant to the terms of this Agreement. In performing its functions and duties hereunder, the Agent shall act solely as an agent of Lenders and does not assume and shall not be deemed to have assumed any obligation towards or relationship of agency or trust with or for the Borrower or any of its Subsidiaries. The Agent shall not have, by reason hereof or any of the other Loan Documents, a fiduciary relationship in respect of any Lender; and nothing herein or any of the other Loan Documents, expressed or implied, is intended to or shall be so construed as to impose upon the Agent any obligations in respect hereof or any of the other Loan Documents except as expressly set forth herein or therein.

Neither the Agent nor any of its directors, officers, agents or employees shall be liable for any action taken or omitted to be taken by it or them under or in connection with this Agreement, except for its or their own gross negligence or willful misconduct. Without limitation of the generality of the foregoing, the Agent: (i) may treat the Lender that made any Advance as the holder of the Debt resulting therefrom until the Agent receives and accepts an Assignment and Acceptance entered into by such Lender, as assignor, and an Eligible Assignee, as assignee, as provided in Section 8.07; (ii) may consult with legal counsel (including counsel for the Borrower), independent public accountants and other experts selected by it and shall not be liable for any action taken or omitted to be taken in good faith by it in accordance with the advice of such counsel, accountants or experts; (iii) makes no warranty or representation to any Lender and shall not be responsible to any Lender for any statements, warranties or representations (whether written or oral) made in or in connection with this Agreement; (iv) shall not have any duty to ascertain or to inquire as to the performance, observance or satisfaction of any of the terms, covenants or conditions of this Agreement on the part of the Borrower or the existence at any time of any Default or to inspect the property (including the books and records) of the Borrower; (v) shall not be responsible to any Lender for the due execution, legality, validity, enforceability, genuineness, sufficiency or value of, or the perfection or priority of any lien or security interest created or purported to be created under or in connection with, this Agreement or any other instrument or document furnished pursuant hereto; and (vi) shall incur no liability under or in respect of this Agreement by acting upon any notice, consent, certificate or other instrument or writing (which may be by telecopier or telegram) believed by it to be genuine and signed or sent by the proper party or parties.

SECTION 7.03 GSCP and Affiliates. With respect to its Commitments, the Advances made by it and the Note, if any, issued to it, GSCP shall have the same rights and powers under this Agreement as any other Lender and may exercise the same as though it were not the Agent; and the term “Lender” or “Lenders” shall, unless otherwise expressly indicated, include GSCP in its individual capacity. GSCP and its Affiliates may accept deposits from, lend money to, act as trustee under indentures of, accept investment banking engagements from and generally engage in any kind of business with, the Borrower, any of its Subsidiaries and any Person who may do business with or own securities of the Borrower or any such Subsidiary, all as if GSCP were not the Agent and without any duty to account therefor to the Lenders. The Agent shall have no duty to disclose any information obtained or received by it or any of its Affiliates relating to the Borrower or any of its Subsidiaries to the extent such information was obtained or received in any capacity other than as Agent. In the event that GSCP or any of its Affiliates shall be or become an indenture trustee under the Trust Indenture Act of 1939 (as amended, the “Trust Indenture Act”) in respect of any securities issued or guarantied by the Borrower, the parties hereto acknowledge and agree that any payment or property received in satisfaction of or in respect of any obligation of the Borrower hereunder or under any other Loan Document by or on behalf of GSCP in its capacity as the Agent for the benefit of any Lender under this Agreement or any Note (other than GSCP or an Affiliate of GSCP) and which is applied in accordance with this Agreement shall be deemed to be exempt from the requirements of Section 311 of the Trust Indenture Act pursuant to Section 311(b)(3) of the Trust Indenture Act.

SECTION 7.04 Lender Credit Decision. Each Lender acknowledges that it has, independently and without reliance upon the Agent or any other Lender and based on the

financial statements referred to in Section 4.01 and such other documents and information as it has deemed appropriate, made its own credit analysis and decision to enter into this Agreement. Each Lender also acknowledges that it will, independently and without reliance upon the Agent or any other Lender and based on such documents and information as it shall deem appropriate at the time, continue to make its own credit decisions in taking or not taking action under this Agreement.

SECTION 7.05 Indemnification.

(a) The Lenders agree to indemnify the Agent (to the extent not reimbursed by the Borrower), ratably according to the sum of the respective principal amounts of the Advances then owed to each of them and the Unused Commitments of each of them (or if no Advances are at the time outstanding, ratably according to the respective amounts of their Commitments), from and against any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind or nature whatsoever that may be imposed on, incurred by, or asserted against the Agent in any way relating to or arising out of this Agreement or any action taken or omitted by the Agent in its capacity as such under this Agreement (collectively, the “Indemnified Costs”), provided that no Lender shall be liable for any portion of the Indemnified Costs resulting from the Agent’s gross negligence or willful misconduct. Without limitation of the foregoing, each Lender agrees to reimburse the Agent promptly upon demand for its ratable share of any out-of-pocket expenses (including counsel fees) incurred by the Agent in connection with the preparation, execution, delivery, administration, modification, amendment or enforcement (whether through negotiations, legal proceedings or otherwise) of, or legal advice in respect of rights or responsibilities under, this Agreement, to the extent that the Agent is not reimbursed for such expenses by the Borrower. In the case of any investigation, litigation or proceeding giving rise to any Indemnified Costs, this Section 7.05 applies whether any such investigation, litigation or proceeding is brought by the Agent, any Lender or a third party.

(b) The failure of any Lender to reimburse the Agent promptly upon demand for its Ratable Share of any amount required to be paid by the Lenders to the Agent as provided herein shall not relieve any other Lender of its obligation hereunder to reimburse the Agent for its Ratable Share of such amount, but no Lender shall be responsible for the failure of any other Lender to reimburse the Agent for such other Lender’s Ratable Share of such amount. Without prejudice to the survival of any other agreement of any Lender hereunder, the agreement and obligations of each Lender contained in this Section 7.05 shall survive the payment in full of principal, interest and all other amounts payable hereunder and under the Notes. The Agent agrees to return to the Lenders their respective Ratable Shares of any amounts paid under this Section 7.05 that are subsequently reimbursed by the Borrower.

SECTION 7.06 Successor Agent. The Agent may resign at any time by giving written notice thereof to the Lenders and the Borrower and may be removed at any time with or without cause by the Required Lenders. Upon any such resignation or removal, the Required Lenders shall have the right to appoint a successor Agent with the consent of the Borrower, not to be unreasonably withheld or delayed. If the Required Lenders have not appointed a successor Agent, the Agent shall have the right to appoint a financial institution to act as Agent hereunder with the consent of the Borrower, not to be unreasonably withheld or delayed, and in any case,

the Agent’s resignation shall become effective on the thirtieth day after such notice of resignation. If neither the Required Lenders nor the Agent have appointed a successor Agent, the Required Lenders shall be deemed to succeed to and become vested with all the rights, powers, privileges and duties of the retiring Agent. Upon the acceptance of any appointment as Agent hereunder by a successor Agent, such successor Agent shall thereupon succeed to and become vested with all the rights, powers, discretion, privileges and duties of the retiring Agent, and the retiring Agent shall be discharged from its duties and obligations under this Agreement. After any retiring Agent’s resignation or removal hereunder as Agent, the provisions of this Article VII shall inure to its benefit as to any actions taken or omitted to be taken by it while it was Agent under this Agreement.

All such notices and communications shall, when mailed, telecopied or e-mailed, be effective when deposited in the mails, telecopied or confirmed by e-mail, respectively, except that notices and communications to the Agent pursuant to Article II, III or VII shall not be effective until received by the Agent. Delivery by telecopier of an executed counterpart of any amendment or waiver of any provision of this Agreement or the Notes or of any Exhibit hereto to be executed and delivered hereunder shall be effective as delivery of a manually executed counterpart thereof.

(b) So long as GSCP or any of its Affiliates is the Agent, materials required to be delivered pursuant to Section 5.01(i)(i), (ii) and (iv) shall be delivered to the Agent in an electronic medium in a format acceptable to the Agent and the Lenders by e-mail at ***@***. The Borrower agrees that the Agent may make such materials, as well as any other written information, documents, instruments and other material relating to the Borrower, any of its Subsidiaries or any other materials or matters relating to this Agreement, the Notes or any of the transactions contemplated hereby (collectively, the “Communications”) available to the Lenders by posting such notices on Intralinks or a substantially similar electronic system (the “Platform”). The Borrower acknowledges that (i) the distribution of material through an electronic medium is not necessarily secure and that there are confidentiality and other risks associated with such distribution, (ii) the Platform is provided “as is” and “as available” and (iii) neither the Agent nor any of its Affiliates warrants the accuracy, adequacy or completeness of the Communications or the Platform and each expressly disclaims liability for errors or omissions in the Communications or the Platform. No warranty of any kind, express, implied or statutory, including, without limitation, any warranty of merchantability, fitness for a particular purpose, non-infringement of third party rights or freedom from viruses or other code defects, is made by the Agent or any of its Affiliates in connection with the Platform.

(c) The Borrower and each Lender acknowledge that certain of the Lenders may be “public-side” Lenders (Lenders that do not wish to receive material non-public information with respect to the Borrower, its Subsidiaries or their securities) and, if documents or notices required to be delivered pursuant to this Agreement or otherwise are being distributed through the Platform, any document or notice that the Borrower has indicated contains material non-public information with respect to the Borrower, its Subsidiaries or their securities shall not be posted on that portion of the Platform designated for such public-side Lenders. If the Borrower has not indicated whether a document or notice delivered pursuant to this Agreement contains any such material non-public information, the Agent reserves the right to post such document or notice solely on that portion of the Platform designated for Lenders who wish to receive material nonpublic information with respect to the Borrower, its Subsidiaries and their securities.

(d) Each Lender agrees that notice to it (as provided in the next sentence) (a “Notice”) specifying that any Communications have been posted to the Platform shall

constitute effective delivery of such information, documents or other materials to such Lender for purposes of this Agreement; provided that if requested by any Lender the Agent shall deliver a copy of the Communications to such Lender by email or telecopier. Each Lender agrees (i) to notify the Agent in writing of such Lender’s e-mail address to which a Notice may be sent by electronic transmission (including by electronic communication) on or before the date such Lender becomes a party to this Agreement (and from time to time thereafter to ensure that the Agent has on record an effective e-mail address for such Lender) and (ii) that any Notice may be sent to such e-mail address.

SECTION 8.03 No Waiver; Remedies. No failure on the part of any Lender or the Agent to exercise, and no delay in exercising, any right hereunder or under any Note shall operate as a waiver thereof; nor shall any single or partial exercise of any such right preclude any other or further exercise thereof or the exercise of any other right. The remedies herein provided are cumulative and not exclusive of any remedies provided by law.

SECTION 8.04 Costs and Expenses. (a) The Borrower agrees to pay on demand all reasonable documented out of pocket costs and expenses of the Agent in connection with the preparation, execution, delivery, modification and amendment of this Agreement, the Notes and the other documents to be delivered hereunder, including, without limitation, (A) all due diligence, syndication (including printing, distribution and bank meetings), transportation, computer, duplication, appraisal, consultant, and audit expenses and (B) the reasonable fees and expenses of counsel for the Agent with respect thereto and with respect to advising the Agent as to its rights and responsibilities under this Agreement. The Borrower further agrees to pay on demand all costs and expenses of the Agent and the Lenders, if any (including, without limitation, reasonable counsel fees and expenses), in connection with the enforcement (whether through negotiations, legal proceedings or otherwise) of this Agreement, the Notes and the other documents to be delivered hereunder, including, without limitation, reasonable fees and expenses of counsel for the Agent and each Lender in connection with the enforcement of rights under this Section 8.04(a).

(b) The Borrower agrees to indemnify and hold harmless the Agent and each Lender and each of their Affiliates and their officers, directors, partners, employees, agents and advisors (each, an “Indemnified Party”) from and against any and all claims, damages, losses, penalties, liabilities and expenses (including, without limitation, reasonable fees and expenses of counsel) incurred by or asserted or awarded against any Indemnified Party, in each case arising out of or in connection with or by reason of (including, without limitation, in connection with any investigation, litigation or proceeding or preparation of a defense in connection therewith) (i) the Notes, this Agreement, any of the transactions contemplated herein or the actual or proposed use of the proceeds of the Advances or (ii) the actual or alleged presence of Hazardous Materials on any property of the Borrower or any of its Subsidiaries or any Environmental Action relating in any way to the Borrower or any of its Subsidiaries, except to the extent such claim, damage, loss, liability or expense has resulted from such Indemnified Party’s gross negligence or bad faith. In the case of an investigation, litigation or other proceeding to which the indemnity in this Section 8.04(b) applies, such indemnity shall be effective whether or not such investigation, litigation or proceeding is brought by the Borrower, its directors, equityholders or creditors or an Indemnified Party or any other Person, whether or not any Indemnified Party is otherwise a party thereto and whether or not the transactions contemplated hereby are consummated. The

Borrower also agrees not to assert any claim for special, indirect, consequential or punitive damages against the Agent, any Lender, any of their Affiliates, or any of their respective directors, officers, partners, employees, attorneys and agents, on any theory of liability, arising out of or otherwise relating to the Notes, this Agreement, any of the transactions contemplated herein or the actual or proposed use of the proceeds of the Advances. To the extent duplicative of the provisions of Section 2.14, this Section 8.04 shall not apply to Taxes or Other Taxes.

(c) If any payment of principal of, or Conversion of, any Eurodollar Rate Advance is made by the Borrower to or for the account of a Lender other than on the last day of the Interest Period for such Advance, as a result of a payment or Conversion pursuant to Section 2.07(d) or (e), 2.10 or 2.12, acceleration of the maturity of the Notes pursuant to Section 6.01 or for any other reason, or by an Eligible Assignee to a Lender other than on the last day of the Interest Period for such Advance upon an assignment of rights and obligations under this Agreement pursuant to Section 8.07 as a result of a demand by the Borrower pursuant to Section 8.07(a), the Borrower shall, upon demand by such Lender (with a copy of such demand to the Agent), pay to the Agent for the account of such Lender any amounts required to compensate such Lender for any additional losses, costs or expenses that it may reasonably incur as a result of such payment or Conversion, including, without limitation, any loss (including loss of anticipated profits), cost or expense incurred by reason of the liquidation or reemployment of deposits or other funds acquired by any Lender to fund or maintain such Advance.

(d) Without prejudice to the survival of any other agreement of the Borrower hereunder, the agreements and obligations of the Borrower contained in Sections 2.11, 2.14 and 8.04 shall survive the payment in full of principal, interest and all other amounts payable hereunder and under the Notes.

SECTION 8.05 Right of Set-off. Upon either (a) the occurrence and during the continuance of any Event of Default under Section 6.01(a) or 6.01(e) or (b) (i) the occurrence and during the continuance of any other Event of Default and (ii) the making of the request or the granting of the consent specified by Section 6.01 to authorize the Agent to declare the Notes due and payable pursuant to the provisions of Section 6.01, each Lender and each of its Affiliates is hereby authorized at any time and from time to time, to the fullest extent permitted by law, to set off and apply any and all deposits (general or special, time or demand, provisional or final) at any time held and other indebtedness at any time owing by such Lender or such Affiliate to or for the credit or the account of the Borrower against any and all of the obligations of the Borrower now or hereafter existing under this Agreement and the Note held by such Lender, whether or not such Lender shall have made any demand under this Agreement or such Note and although such obligations may be unmatured. Each Lender agrees promptly to notify the Borrower after any such set-off and application, provided that the failure to give such notice shall not affect the validity of such set-off and application. The rights of each Lender and its Affiliates under this Section are in addition to other rights and remedies (including, without limitation, other rights of set-off) that such Lender and its Affiliates may have.

SECTION 8.06 Binding Effect. This Agreement shall become effective (other than Section 2.01, which shall only become effective upon satisfaction of the conditions precedent set forth in Section 3.01) when it shall have been executed by the Borrower and the Agent and when the Agent shall have been notified by each Initial Lender that such Initial Lender has executed it

and thereafter shall be binding upon and inure to the benefit of the Borrower, the Agent and each Lender and their respective successors and assigns, except that the Borrower shall not have the right to assign its rights hereunder or any interest herein without the prior written consent of the Lenders.

SECTION 8.07 Assignments and Participations. (a) Each Lender may and, if demanded by the Borrower (so long as no Default shall have occurred and be continuing and following a demand by such Lender pursuant to Section 2.11 or 2.14) upon at least five Business Days’ notice to such Lender and the Agent, will, assign to one or more Persons all or a portion of its rights and obligations under this Agreement (including, without limitation, all or a portion of its Commitment, the Advances owing to it and the Note or Notes held by it); provided, however, that (i) each such assignment shall be of a constant, and not a varying, percentage of all rights and obligations under this Agreement, (ii) except in the case of an assignment to a Person that, immediately prior to such assignment, was a Lender or an assignment of all of a Lender’s rights and obligations under this Agreement, the amount of the Commitment of the assigning Lender being assigned pursuant to each such assignment (determined as of the date of the Assignment and Acceptance with respect to such assignment) shall in no event be less than $5,000,000 or an integral multiple of $1,000,000 in excess thereof, (iii) each such assignment shall be to an Eligible Assignee, (iv) each such assignment made as a result of a demand by the Borrower pursuant to this Section 8.07(a) shall be arranged by the Borrower after consultation with the Agent and shall be either an assignment of all of the rights and obligations of the assigning Lender under this Agreement or an assignment of a portion of such rights and obligations made concurrently with another such assignment or other such assignments that together cover all of the rights and obligations of the assigning Lender under this Agreement, (v) no Lender shall be obligated to make any such assignment as a result of a demand by the Borrower pursuant to this Section 8.07(a) unless and until such Lender shall have received one or more payments from either the Borrower or one or more Eligible Assignees in an aggregate amount at least equal to the aggregate outstanding principal amount of the Advances owing to such Lender, together with accrued interest thereon to the date of payment of such principal amount and all other amounts accrued or payable to such Lender under this Agreement, and (vi) the parties to each such assignment shall execute and deliver to the Agent, for its acceptance and recording in the Register, an Assignment and Acceptance, together with any Note subject to such assignment and a processing and recordation fee of $3,500 payable by the parties to each such assignment, provided, however, that in the case of each assignment made as a result of a demand by the Borrower, such recordation fee shall be payable by the Borrower except that no such recordation fee shall be payable in the case of an assignment made at the request of the Borrower to an Eligible Assignee that is an existing Lender. Upon such execution, delivery, acceptance and recording, from and after the effective date specified in each Assignment and Acceptance, (x) the assignee thereunder shall be a party hereto and, to the extent that rights and obligations hereunder have been assigned to it pursuant to such Assignment and Acceptance, have the rights and obligations of a Lender hereunder and (y) the Lender assignor thereunder shall, to the extent that rights and obligations hereunder have been assigned by it pursuant to such Assignment and Acceptance, relinquish its rights (other than its rights under Sections 2.11, 2.14 and 8.04 to the extent any claim thereunder relates to an event arising prior to such assignment) and be released from its obligations (other than its obligations under Section 7.05 to the extent any claim thereunder relates to an event arising prior to such assignment) under this Agreement (and, in the case of an Assignment and Acceptance covering all or the remaining portion of an assigning

Lender’s rights and obligations under this Agreement, such Lender shall cease to be a party hereto).

(b) By executing and delivering an Assignment and Acceptance, the Lender assignor thereunder and the assignee thereunder confirm to and agree with each other and the other parties hereto as follows: (i) other than as provided in such Assignment and Acceptance, such assigning Lender makes no representation or warranty and assumes no responsibility with respect to any statements, warranties or representations made in or in connection with this Agreement or the execution, legality, validity, enforceability, genuineness, sufficiency or value of, or the perfection or priority of any lien or security interest created or purported to be created under or in connection with, this Agreement or any other instrument or document furnished pursuant hereto; (ii) such assigning Lender makes no representation or warranty and assumes no responsibility with respect to the financial condition of the Borrower or the performance or observance by the Borrower of any of its obligations under this Agreement or any other instrument or document furnished pursuant hereto; (iii) such assignee confirms that it has received a copy of this Agreement, together with copies of the financial statements referred to in Section 4.01 and such other documents and information as it has deemed appropriate to make its own credit analysis and decision to enter into such Assignment and Acceptance; (iv) such assignee will, independently and without reliance upon the Agent, such assigning Lender or any other Lender and based on such documents and information as it shall deem appropriate at the time, continue to make its own credit decisions in taking or not taking action under this Agreement; (v) such assignee confirms that it is an Eligible Assignee; (vi) such assignee appoints and authorizes the Agent to take such action as agent on its behalf and to exercise such powers and discretion under this Agreement as are delegated to the Agent by the terms hereof, together with such powers and discretion as are reasonably incidental thereto; and (vii) such assignee agrees that it will perform in accordance with their terms all of the obligations that by the terms of this Agreement are required to be performed by it as a Lender.

(c) Upon its receipt of an Assignment and Acceptance executed by an assigning Lender and an assignee representing that it is an Eligible Assignee, together with any Note or Notes subject to such assignment, the Agent shall, if such Assignment and Acceptance has been completed and is in substantially the form of Exhibit C hereto, (i) accept such Assignment and Acceptance, (ii) record the information contained therein in the Register and (iii) give prompt notice thereof to the Borrower.

(d) The Agent, acting for this purpose as an agent of the Borrower, shall maintain at its address referred to in Section 8.02 a copy of each Assignment and Acceptance delivered to and accepted by it and a register for the recordation of the names and addresses of the Lenders and the Commitment of, and principal amount of the Advances owing to, each Lender from time to time (the “Register”). The entries in the Register shall be conclusive and binding for all purposes, absent manifest error, and the Borrower, the Agent and the Lenders may treat each Person whose name is recorded in the Register as a Lender hereunder for all purposes of this Agreement. The Register shall be available for inspection by the Borrower or any Lender at any reasonable time and from time to time upon reasonable prior notice.

(e) Each Lender may sell participations to one or more banks or other entities (other than the Borrower or any of its Affiliates) in or to all or a portion of its rights and

obligations under this Agreement (including, without limitation, all or a portion of its Commitment, the Advances owing to it and any Note or Notes held by it); provided, however, that (i) such Lender’s obligations under this Agreement (including, without limitation, its Commitment to the Borrower hereunder) shall remain unchanged, (ii) such Lender shall remain solely responsible to the other parties hereto for the performance of such obligations, (iii) such Lender shall remain the holder of any such Note for all purposes of this Agreement, (iv) the Borrower, the Agent and the other Lenders shall continue to deal solely and directly with such Lender in connection with such Lender’s rights and obligations under this Agreement and (v) no participant under any such participation shall have any right to approve any amendment or waiver of any provision of this Agreement or any Note, or any consent to any departure by the Borrower therefrom, except to the extent that such amendment, waiver or consent would reduce the principal of, or interest on, the Notes or any fees or other amounts payable hereunder, in each case to the extent subject to such participation, or postpone any date fixed for any payment of principal of, or interest on, the Notes or any fees or other amounts payable hereunder, in each case to the extent subject to such participation. Each Lender shall, acting for this purpose as an agent of the Borrower, maintain at one of its offices a register substantially similar to the Register (the “Participant Register”) for the recordation of the names and addresses of its participants, and the amount and terms of its participations; provided that no Lender shall be required to disclose or share the information contained in its Participant Register with the Borrower or any other person, except as required by applicable law. No sale of participating interests in the rights of a Lender hereunder and under the other Loan Documents shall be effective until properly recorded in the Participant Register.

(f) Any Lender may, in connection with any assignment or participation or proposed assignment or participation pursuant to this Section 8.07, disclose to the assignee or participant or proposed assignee or participant, any information relating to the Borrower furnished to such Lender by or on behalf of the Borrower; provided that, prior to any such disclosure, the assignee or participant or proposed assignee or participant shall agree to preserve the confidentiality of any Borrower Information relating to the Borrower received by it from such Lender.

(g) Notwithstanding any other provision set forth in this Agreement, any Lender may at any time create a security interest in all or any portion of its rights under this Agreement (including, without limitation, the Advances owing to it and any Note or Notes held by it) in favor of any Federal Reserve Bank in accordance with Regulation A of the Board of Governors of the Federal Reserve System.

SECTION 8.08 Confidentiality. Neither the Agent nor any Lender may disclose to any Person any confidential, proprietary or non-public information of the Borrower furnished to the Agent or the Lenders by the Borrower and identified as such in writing (such information being referred to collectively herein as the “Borrower Information”), except that each of the Agent and each of the Lenders may disclose Borrower Information (i) to its and its affiliates’ employees, officers, directors, agents and advisors (it being understood that the Persons to whom such disclosure is made will be informed of the confidential nature of such Borrower Information and instructed to keep such Borrower Information confidential on substantially the same terms as provided herein), (ii) to the extent requested by any regulatory authority, (iii) to the extent required by applicable laws or regulations or by any subpoena or similar legal process, (iv) to

any other party to this Agreement, (v) in connection with the exercise of any remedies hereunder or any suit, action or proceeding relating to this Agreement or the enforcement of rights hereunder, (vi) subject to an agreement containing provisions substantially the same as those of this Section 8.08, to any assignee or participant or prospective assignee or participant or to any direct, indirect, actual or prospective counterparty (and its advisor) to any swap, derivative or securitization transaction related to the obligations of the Borrower under this Agreement, (vii) to the extent such Borrower Information (A) is or becomes generally available to the public on a non-confidential basis other than as a result of a breach of this Section 8.08 by the Agent or such Lender, or (B) is or becomes available to the Agent or such Lender on a nonconfidential basis from a source other than the Borrower and (viii) with the consent of the Borrower. In addition, the Agent and each Lender may disclose the existence of this Agreement and the information about this Agreement to market data collectors, similar services providers to the lending industry, and service providers to the Agent and the Lenders in connection with the administration and management of this Agreement and the other Loan Documents.

SECTION 8.09 Governing Law. This Agreement and the other Loan Documents (except as otherwise expressly set forth in any such Loan Document), and the rights and obligations of the parties hereunder and thereunder, shall be governed by, and shall be construed and enforced in accordance with, the laws of the State of New York.

SECTION 8.10 Execution in Counterparts. This Agreement may be executed in any number of counterparts and by different parties hereto in separate counterparts, each of which when so executed shall be deemed to be an original and all of which taken together shall constitute one and the same agreement. Delivery of an executed counterpart of a signature page to this Agreement by telecopier shall be effective as delivery of a manually executed counterpart of this Agreement.

SECTION 8.11 Jurisdiction, Etc. (a) Each of the parties hereto hereby irrevocably and unconditionally submits, for itself and its property, to the nonexclusive jurisdiction of any New York State court or federal court of the United States of America sitting in New York City, and any appellate court from any thereof, in any action or proceeding arising out of or relating to this Agreement or the Notes, or for recognition or enforcement of any judgment, and each of the parties hereto hereby irrevocably and unconditionally agrees that all claims in respect of any such action or proceeding may be heard and determined in any such New York State court or, to the extent permitted by law, in such federal court. The Borrower hereby further consents to the service of process in any action or proceeding in such courts by the mailing thereof by any parties hereto by registered or certified mail, postage prepaid, to the Borrower at its address specified pursuant to Section 8.02. Each of the parties hereto agrees that a final judgment in any such action or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by law. Nothing in this Agreement shall affect any right that any party may otherwise have to bring any action or proceeding relating to this Agreement or the Notes in the courts of any jurisdiction.

(b) Each of the parties hereto irrevocably and unconditionally waives, to the fullest extent it may legally and effectively do so, any objection that it may now or hereafter have to the laying of venue of any suit, action or proceeding arising out of or relating to this Agreement or the Notes in any New York State or federal court. Each of the parties hereto

hereby irrevocably waives, to the fullest extent permitted by law, the defense of an inconvenient forum to the maintenance of such action or proceeding in any such court.

SECTION 8.12 Patriot Act Notice. Each Lender and the Agent (for itself and not on behalf of any Lender) hereby notifies the Borrower that pursuant to the requirements of the Patriot Act, it is required to obtain, verify and record information that identifies the Borrower, which information includes the name and address of the Borrower and other information that will allow such Lender or the Agent, as applicable, to identify the Borrower in accordance with the Patriot Act. The Borrower shall provide, to the extent commercially reasonable, such information and take such actions as are reasonably requested by the Agent or any Lenders in order to assist the Agent and the Lenders in maintaining compliance with the Patriot Act.

SECTION 8.13 Waiver of Jury Trial. Each of the Borrower, the Agent and the Lenders hereby irrevocably waives all right to trial by jury in any action, proceeding or counterclaim (whether based on contract, tort or otherwise) arising out of or relating to this Agreement or the Notes or the actions of the Agent or any Lender in the negotiation, administration, performance or enforcement thereof.

SECTION 8.14 No Fiduciary Duty. The Agent, each Lender and their Affiliates (collectively, solely for purposes of this paragraph, the “Lenders”), may have economic interests that conflict with those of the Borrower. The Borrower agrees that nothing in the Loan Documents or otherwise will be deemed to create an advisory, fiduciary or agency relationship or fiduciary or other implied duty between the Lenders and the Borrower, its stockholders or its affiliates. The Borrower acknowledges and agrees that (i) the transactions contemplated by the Loan Documents are arm’s-length commercial transactions between the Lenders, on the one hand, and the Borrower, on the other, (ii) in connection therewith and with the process leading to such transaction each of the Lenders is acting solely as a principal and not the agent or fiduciary of the Borrower, its management, stockholders, creditors or any other person, (iii) no Lender has assumed an advisory or fiduciary responsibility in favor of the Borrower with respect to the transactions contemplated hereby or the process leading thereto (irrespective of whether any Lender or any of its affiliates has advised or is currently advising the Borrower on other matters) or any other obligation to the Borrower except the obligations expressly set forth in the Loan Documents and (iv) the Borrower has consulted its own legal and financial advisors to the extent it deemed appropriate. The Borrower further acknowledges and agrees that it is responsible for making its own independent judgment with respect to such transactions and the process leading thereto. The Borrower agrees that it will not claim that any Lender has rendered advisory services of any nature or respect, or owes a fiduciary or similar duty to the Borrower, in connection with such transaction or the process leading thereto.

IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be executed by their respective officers thereunto duly authorized, as of the date first above written.

EXHIBIT A — FORM OF NOTE

U.S.$ ____________________

Dated: ___________, 2007

FOR VALUE RECEIVED, the undersigned, WESTERN DIGITAL TECHNOLOGIES, INC., a Delaware corporation (the “Borrower”), HEREBY PROMISES TO PAY to the order of ___(the “Lender”) for the account of its Applicable Lending Office on the Maturity Date (each as defined in the Credit Agreement referred to below) the principal sum of U.S.$[amount of the Lender’s Commitment in figures] or, if less, the unpaid principal amount of all Advances made by the Lender to the Borrower pursuant to the Credit Agreement dated as of August 30, 2007 among the Borrower, the Lender and certain other lenders party thereto, Citicorp Global Capital Markets and JPMorgan Chase Bank, N.A., as co-syndication agents, and Goldman Sachs Credit Partners L.P., as Agent for the Lender and such other lenders (as amended, supplemented or otherwise modified from time to time, the “Credit Agreement”; the terms defined therein and not otherwise defined herein being used herein as therein defined).

The Borrower promises to pay interest on the unpaid principal amount of each Advance from the date of such Advance until such principal amount is paid in full, at such interest rates, and payable at such times, as are specified in the Credit Agreement.

Both principal and interest are payable in lawful money of the United States of America to GSCP, as Agent, at the Agent’s Account, in same day funds. Each Advance owing to the Lender by the Borrower pursuant to the Credit Agreement, and all payments made on account of principal thereof, shall be recorded by the Lender and, prior to any transfer hereof, endorsed on the grid attached hereto which is part of this Promissory Note.

This Promissory Note is one of the Notes referred to in, and is entitled to the benefits of, the Credit Agreement. The Credit Agreement, among other things, (i) provides for the making of Advances by the Lender to the Borrower from time to time in an aggregate amount not to exceed at any time outstanding the U.S. dollar amount first above mentioned, the indebtedness of the Borrower resulting from each such Advance being evidenced by this Promissory Note and (ii) contains provisions for acceleration of the maturity hereof upon the happening of an Event of Default and also for prepayments on account of principal hereof prior to the maturity hereof upon the terms and conditions therein specified.

Whenever any payment on this Promissory Note shall be stated to be due on a day other than a Business Day, such payment shall be made on the next succeeding Business Day, and such extension of time shall be included in the computation of the payment of interest on this Promissory Note; provided, however, that if such extension would cause payment of interest on or principal of Eurodollar Rate Advances to be made in the next following calendar month, such payment shall be made on the next preceding Business Day.

This Promissory Note is subject to restrictions on transfer or assignment as provided in the Credit Agreement.

This Promissory Note and the rights and obligations of the Borrower and the Lender hereunder shall be governed by, and shall be construed and enforced in accordance with, the laws of the State of New York.
