The Obligors have authorized the issue and sale of $450,000,000 aggregate principal amount of its Senior Notes consisting of (i) $50,000,000 aggregate principal amount of their 4.63% Senior Notes, Series A-1, due March 25, 2013 (the “Series A-1 Notes”); (ii) $250,000,000 aggregate principal amount of their 5.17% Senior Notes, Series A-2, due March 25, 2015 (the “Series A-2 Notes”); and (iii) $150,000,000 aggregate principal amount of

their 5.75% Senior Notes, Series A-3, due March 25, 2018 (the “Series A-3 Notes” and, collectively with the Series A-1 Notes and the Series A-2 Notes, the “Notes,” such term to include any such notes issued in substitution therefor pursuant to Section 13 of this Agreement). The Notes shall be substantially in the forms set out in Exhibits 1(a) through 1(c), with such changes therefrom, if any, as may be approved by you and the Company. Certain capitalized terms used in this Agreement are defined in Schedule B; references to a “Schedule” or an “Exhibit” are, unless otherwise specified, to a Schedule or an Exhibit attached to this Agreement.

1.2. Additional Interest.

If the Debt to Adjusted EBITDA Ratio at any time exceeds 3.50 to 1.00, as evidenced by an Officer’s Certificate delivered pursuant to Section 7.2(a), the interest rate payable on the Notes shall be increased by 0.75% (the “Incremental Interest”). Such Incremental Interest shall begin to accrue on the first day of the fiscal quarter following the fiscal quarter in respect of which such Certificate was delivered, and shall continue to accrue until the Company has provided an Officer’s Certificate pursuant to Section 7.2(a) demonstrating that, as of the last day of the fiscal quarter in respect of which such Certificate is delivered, the Debt to Adjusted EBITDA Ratio is not more than 3.50 to 1.00. In the event such Officer’s Certificate is delivered, the Incremental Interest shall cease to accrue on the last day of the fiscal quarter in respect of which such Certificate is delivered.

2. SALE AND PURCHASE OF NOTES.

Subject to the terms and conditions of this Agreement, the Obligors will issue and sell to you and each of the other purchasers named in Schedule A (the “Other Purchasers”), and you and the Other Purchasers will purchase from the Obligors, at the Closing provided for in Section 3, Notes in the principal amount and series specified opposite your names in Schedule A at the purchase price of 100% of the principal amount thereof. Your obligation hereunder and the obligations of the Other Purchasers are several and not joint obligations and you shall have no liability to any Person for the performance or non-performance by any Other Purchaser hereunder.

2

5. REPRESENTATIONS AND WARRANTIES OF THE COMPANY.

Each Obligor represents and warrants to you that:

5.1. Organization; Power and Authority.

Each Obligor is a corporation or limited partnership duly organized, validly existing and in good standing under the laws of its jurisdiction of organization, and is duly qualified as a foreign corporation or foreign limited partnership and is in good standing in each jurisdiction in which such qualification is required by law, other than those jurisdictions as to which the failure to be so qualified or in good standing could not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect. Each Obligor has the corporate or partnership power and authority to own or hold under lease the properties it purports to own or hold under lease, to transact the business it transacts and proposes to transact, to execute and deliver this Agreement and the Notes and to perform the provisions hereof and thereof.

5.2. Authorization, etc.

This Agreement and the Notes have been duly authorized by all necessary corporate or partnership action on the part of each Obligor, and this Agreement constitutes, and upon execution and delivery thereof each Note will constitute, a legal, valid and binding obligation of each Obligor enforceable against each Obligor in accordance with its terms, except as such enforceability may be limited by (i) applicable bankruptcy, insolvency, reorganization, moratorium or other similar laws affecting the enforcement of creditors’ rights generally and (ii) general principles of equity (regardless of whether such enforceability is considered in a proceeding in equity or at law).

5

5.3. Disclosure.

The Obligors, through their agent, J.P. Morgan Securities Inc., have delivered to you and each Other Purchaser a copy of a Confidential Private Placement Memorandum, dated February 2008, including the Company’s Annual Reports on Form 10-K for the fiscal years ended April 28, 2007 and April 29, 2006, the Company’s Quarterly Report on Form 10-Q for the fiscal quarters ended January 26, 2008 and October 27 and July 28, 2007 (the “Memorandum”), relating to the transactions contemplated hereby.

Except as disclosed in Schedule 5.3, this Agreement, the Memorandum, the documents, certificates or other writings delivered to you by or on behalf of the Obligors in connection with the transactions contemplated hereby and the financial statements listed in Schedule 5.5, taken as a whole, do not contain any untrue statement of a material fact or omit to state any material fact necessary to make the statements therein not misleading in light of the circumstances under which they were made.

Each such Subsidiary has the corporate or other power and authority to own or hold under lease the properties it purports to own or hold under lease and to transact the business it transacts and proposes to transact.

6

5.6. Compliance with Laws, Other Instruments, etc.

The execution, delivery and performance by each Obligor of this Agreement and the Notes will not (i) contravene, result in any breach of, or constitute a default under, or result in the creation of any Lien in respect of any property of any Obligor or any other Subsidiary under, any indenture, mortgage, deed of trust, loan, purchase or credit agreement, lease, corporate charter or by-laws, or any other agreement or instrument to which any Obligor or any other Subsidiary is bound or by which any Obligor or any other Subsidiary or any of their respective properties may be bound or affected, (ii) conflict with or result in a breach of any of the terms, conditions or provisions of any order, judgment, decree, or ruling of any court, arbitrator or Governmental Authority applicable to any Obligor or any other Subsidiary or (iii) violate any provision of any statute or other rule or regulation of any Governmental Authority applicable to any Obligor or any other Subsidiary.

The Company knows of no basis for any other tax or assessment that could reasonably be expected to have a Material Adverse Effect. The charges, accruals and reserves on the books of the Company and its Subsidiaries in respect of Federal, state or other taxes for all fiscal periods are adequate.

(c) to the best knowledge of each Obligor, there is no Material violation by any Person of any right of any Obligor or any other Subsidiary with respect to any patent, copyright, service mark, trademark, trade name or other right owned or used by the any Obligor or any other Subsidiary.

5.12. Compliance with ERISA.

(a) The Company and each ERISA Affiliate have operated and administered each Plan in compliance with all applicable laws except for such instances of noncompliance as have not resulted in and could not reasonably be expected to result in a Material Adverse Effect. Neither the Company nor any ERISA Affiliate has incurred any liability pursuant to Title I or IV of ERISA or the penalty or excise tax provisions of the Code relating to employee benefit plans (as defined in Section 3 of ERISA), and no event, transaction or condition has occurred or exists that could reasonably be expected to result in the incurrence of any such liability by the Company or any ERISA Affiliate, or in the imposition of any Lien on any of the rights, properties or assets of the Company or any ERISA Affiliate, in either case pursuant to Title I or IV of ERISA or to such penalty or excise tax provisions or to Section 401(a)(29) or 412 of the Code, other than such liabilities or Liens as would not be individually or in the aggregate Material.

(b) The present value of the aggregate benefit liabilities under each of the Plans (other than Multiemployer Plans), determined as of the end of such Plan’s most recently ended plan year on the basis of the actuarial assumptions specified for funding purposes in such Plan’s most recent actuarial valuation report, did not exceed the aggregate current value of the assets of such Plan allocable to such benefit liabilities. The term “benefit liabilities” has the meaning specified in section 4001 of ERISA and the terms “current value” and “present value” have the meaning specified in section 3 of ERISA.

(c) The Company and its ERISA Affiliates have not incurred withdrawal liabilities (and are not subject to contingent withdrawal liabilities) under section 4201 or 4204 of ERISA in respect of Multiemployer Plans that individually or in the aggregate are Material.

(d) The expected postretirement benefit obligation (determined as of the last day of the Company’s most recently ended fiscal year in accordance with Financial Accounting Standards Board Statement No. 106, without regard to liabilities attributable to continuation coverage mandated by section 4980B of the Code) of the Company and its Subsidiaries is not Material.

(e) The execution and delivery of this Agreement and the issuance and sale of the Notes hereunder will not involve any transaction that is subject to the prohibitions of

9

section 406 of ERISA or in connection with which a tax could be imposed pursuant to section 4975(c)(1)(A)-(D) of the Code. The representation by the Company in the first sentence of this Section 5.12(e) is made in reliance upon and subject to the accuracy of your representation in Section 6.2 as to the sources of the funds used to pay the purchase price of the Notes to be purchased by you.

5.13. Private Offering by the Company.

Neither any Obligor nor anyone acting on its behalf has offered the Notes or any similar securities for sale to, or solicited any offer to buy any of the same from, or otherwise approached or negotiated in respect thereof with, any person other than you and the Other Purchasers and not more than 31 other Institutional Investors, each of which has been offered the Notes at a private sale for investment. Neither any Obligor nor anyone acting on its behalf has taken, or will take, any action that would subject the issuance or sale of the Notes to the registration requirements of Section 5 of the Securities Act.

5.14. Use of Proceeds; Margin Regulations.

The Obligors will apply the proceeds of the sale of the Notes to refinance Debt of the Company as set forth in Schedule 5.14 and for general corporate purposes, including repurchases of the Company’s Capital Stock and business or asset acquisitions. No part of the proceeds from the sale of the Notes will be used, directly or indirectly, for the purpose of buying or carrying any margin stock within the meaning of Regulation U of the Board of Governors of the Federal Reserve System (12 CFR 221) so as to involve any Obligor or any holder of Notes in a violation of such Regulation (or so as to require any holder of Notes to make any filing under such Regulation), or for the purpose of buying or carrying or trading in any securities under such circumstances as to involve any Obligor in a violation of Regulation X of said Board (12 CFR 224) or to involve any broker or dealer in a violation of Regulation T of said Board (12 CFR 220). Margin stock does not constitute more than 10% of the value of the consolidated assets of the Company and its Subsidiaries and the Obligors do not have any present intention that margin stock will constitute more than 10% of the value of such assets. As used in this Section, the terms “margin stock” and “purpose of buying or carrying” shall have the meanings assigned to them in said Regulation U.

5.15. Existing Debt; Future Liens.

(a) Except as described therein, Schedule 5.15 sets forth a complete and correct list of all outstanding Debt of the Company and its Subsidiaries as of March 1, 2008, since which date there has been no Material change in the amounts, interest rates, sinking funds, installment payments or maturities of the Debt of the Company or its Subsidiaries. Neither any Obligor nor any other Subsidiary is in default and no waiver of default is currently in effect, in the payment of any principal or interest on any Debt of any Obligor or any other Subsidiary and no event or condition exists with respect to any Debt of any Obligor or any other Subsidiary that would permit (or that with notice or the lapse of time, or both, would permit) one or more Persons to cause such Debt to become due and payable before its stated maturity or before its regularly scheduled dates of payment.

10

(b) Except as disclosed in Schedule 5.15, neither any Obligor nor any other Subsidiary has agreed or consented to cause or permit in the future (upon the happening of a contingency or otherwise) any of its property, whether now owned or hereafter acquired, to be subject to a Lien not permitted by Section 10.4.

5.16. Foreign Assets Control Regulations, Anti-Terrorism Order, etc.

Neither the sale of the Notes by the Obligors hereunder nor their use of the proceeds thereof will violate (a) the Trading with the Enemy Act, as amended, (b) any of the foreign assets control regulations of the United States Treasury Department (31 CFR, Subtitle B, Chapter V, as amended) or any enabling legislation or executive order relating thereto, (c) the Anti-Terrorism Order or (d) the United States Foreign Corrupt Practices Act of 1997, as amended. Without limiting the foregoing, neither any Obligor nor any other Subsidiary (i) is a blocked person described in Section 1 of the Anti-Terrorism Order or (ii) engages in any dealings or transactions, or is otherwise associated, with any such person.

5.17. Status under Certain Statutes.

Neither any Obligor nor any other Subsidiary is subject to regulation under the Investment Company Act of 1940, as amended, the ICC Termination Act, as amended, or the Federal Power Act, as amended.

5.18. Environmental Matters.

Neither any Obligor nor any other Subsidiary has knowledge of any claim or has received any notice of any claim, and no proceeding has been instituted raising any claim against any Obligor or any other Subsidiary or any of their respective real properties now or formerly owned, leased or operated by any of them or other assets, alleging any damage to the environment or violation of any Environmental Laws, except, in each case, such as could not reasonably be expected to result in a Material Adverse Effect. Except as otherwise disclosed to you in writing,

(a) neither any Obligor nor any other Subsidiary has knowledge of any facts which would give rise to any claim, public or private, of violation of Environmental Laws or damage to the environment emanating from, occurring on or in any way related to real properties now or formerly owned, leased or operated by any of them or to other assets or their use, except, in each case, such as could not reasonably be expected to result in a Material Adverse Effect;

(b) neither any Obligor nor any other Subsidiary has stored any Hazardous Materials on real properties now or formerly owned, leased or operated by any of them and has not disposed of any Hazardous Materials in a manner contrary to any Environmental Laws in each case in any manner that could reasonably be expected to result in a Material Adverse Effect; and

(c) all buildings on all real properties now owned, leased or operated by any Obligor or any other Subsidiary are in compliance with applicable Environmental Laws, except where failure to comply could not reasonably be expected to result in a Material Adverse Effect.

11

5.19. Solvency of Obligors.

After giving effect to the transactions contemplated herein, (i) the present value of the assets of each Obligor, at a fair valuation, is in excess of the amount that will be required to pay its probable liability on its existing debts as said debts become absolute and matured, (ii) each Obligor has received reasonably equivalent value for issuing and selling the Notes, (iii) the property remaining in the hands of each Obligor is not an unreasonably small capital, and (iv) each Obligor is able to pay its debts as they mature.

From and after such date, unless the Obligors shall fail to pay such principal amount when so due and payable, together with the interest and Make-Whole Amount, if any, as aforesaid, interest on such principal amount shall cease to accrue. Any Note paid or prepaid in full shall be surrendered to the Company and canceled and shall not be reissued, and no Note shall be issued in lieu of any prepaid principal amount of any Note.

21

8.6. Purchase of Notes.

The Obligors will not and will not permit any Affiliate to purchase, redeem, prepay or otherwise acquire, directly or indirectly, any of the outstanding Notes except upon the payment or prepayment of the Notes in accordance with the terms of this Agreement and the Notes. The Company will promptly cancel all Notes acquired by any Obligor or any Affiliate pursuant to any payment, prepayment or purchase of Notes pursuant to any provision of this Agreement and no Notes may be issued in substitution or exchange for any such Notes.

8.7. Make-Whole Amount.

The term “ Make-Whole Amount ” means, with respect to any Note, an amount equal to the excess, if any, of the Discounted Value of the Remaining Scheduled Payments with respect to the Called Principal of such Note over the amount of such Called Principal, provided that the Make-Whole Amount may in no event be less than zero. For the purposes of determining the Make-Whole Amount, the following terms have the following meanings:

“ Called Principal ” means, with respect to any Note, the principal of such Note that is to be prepaid pursuant to Section 8.2(a) or has become or is declared to be immediately due and payable pursuant to Section 12.1, as the context requires.

“ Discounted Value ” means, with respect to the Called Principal of any Note, the amount obtained by discounting all Remaining Scheduled Payments with respect to such Called Principal from their respective scheduled due dates to the Settlement Date with respect to such Called Principal, in accordance with accepted financial practice and at a discount factor (applied on the same periodic basis as that on which interest on the Notes is payable) equal to the Reinvestment Yield with respect to such Called Principal.

“ Reinvestment Yield ” means, with respect to the Called Principal of any Note, .50% over the yield to maturity implied by (i) the yields reported, as of 10:00 A.M. (New York City time) on the second Business Day preceding the Settlement Date with respect to such Called Principal, on the display designated as the “PX1 Screen” on the Bloomberg Financial Market Service (or such other display as may replace the PX1 Screen on Bloomberg Financial Market Service) for actively traded U.S. Treasury securities having a maturity equal to the Remaining Average Life of such Called Principal as of such Settlement Date, or (ii) if such yields are not reported as of such time or the yields reported as of such time are not ascertainable (including by way of interpolation), the Treasury Constant Maturity Series Yields reported, for the latest day for which such yields have been so reported as of the second Business Day preceding the Settlement Date with respect to such Called Principal, in Federal Reserve Statistical Release H.15 (519) (or any comparable successor publication) for actively traded U.S. Treasury securities having a constant maturity equal to the Remaining Average Life of such Called Principal as of such Settlement Date. Such implied yield will be determined, if necessary, by (a) converting U.S. Treasury bill quotations to bond-equivalent yields in accordance with accepted financial practice and (b) interpolating linearly between (1) the actively traded U.S. Treasury security with the maturity closest to and greater than the Remaining Average Life and (2) the actively traded U.S. Treasury security with the maturity closest to and less than the Remaining Average Life.

22

“ Remaining Average Life ” means, with respect to any Called Principal, the number of years (calculated to the nearest one-twelfth year) obtained by dividing (i) such Called Principal into (ii) the sum of the products obtained by multiplying (a) the principal component of each Remaining Scheduled Payment with respect to such Called Principal by (b) the number of years (calculated to the nearest one-twelfth year) that will elapse between the Settlement Date with respect to such Called Principal and the scheduled due date of such Remaining Scheduled Payment.

“ Remaining Scheduled Payments ” means, with respect to the Called Principal of any Note, all payments of such Called Principal and interest thereon that would be due after the Settlement Date with respect to such Called Principal if no payment of such Called Principal were made prior to its scheduled due date, provided that if such Settlement Date is not a date on which interest payments are due to be made under the terms of the Notes, then the amount of the next succeeding scheduled interest payment will be reduced by the amount of interest accrued to such Settlement Date and required to be paid on such Settlement Date pursuant to Section 8.2(a) or 12.1.

“ Settlement Date ” means, with respect to the Called Principal of any Note, the date on which such Called Principal is to be prepaid pursuant to Section 8.2(a) or has become or is declared to be immediately due and payable pursuant to Section 12.1, as the context requires.

9. AFFIRMATIVE COVENANTS.

The Obligors, jointly and severally, covenant that so long as any of the Notes are outstanding:

9.1. Compliance with Law.

The Obligors will, and will cause each other Subsidiary to, comply with all laws, ordinances or governmental rules or regulations to which each of them is subject, including, without limitation, Environmental Laws, and will obtain and maintain in effect all licenses, certificates, permits, franchises and other governmental authorizations necessary to the ownership of their respective properties or to the conduct of their respective businesses, in each case to the extent necessary to ensure that non-compliance with such laws, ordinances or governmental rules or regulations or failures to obtain or maintain in effect such licenses, certificates, permits, franchises and other governmental authorizations could not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect.

9.2. Insurance.

The Obligors will, and will cause each other Subsidiary to, maintain, with financially sound and reputable insurers, insurance with respect to their respective properties and businesses against such casualties and contingencies, of such types, on such terms and in such amounts (including deductibles, co-insurance and self-insurance, if adequate reserves are maintained with respect thereto) as is customary in the case of entities of established reputations engaged in the same or a similar business and similarly situated.

23

9.3. Maintenance of Properties.

The Obligors will, and will cause each other Subsidiary to, maintain and keep, or cause to be maintained and kept, their respective properties in good repair, working order and condition (other than ordinary wear and tear), so that the business carried on in connection therewith may be properly conducted at all times, provided that this Section shall not prevent any Obligor or any other Subsidiary from discontinuing the operation and the maintenance of any of its properties if such discontinuance is desirable in the conduct of its business and the Company has concluded that such discontinuance could not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect.

9.4. Payment of Taxes and Claims.

The Obligors will, and will cause each other Subsidiary to, file all income tax or similar tax returns required to be filed in any jurisdiction and to pay and discharge all taxes shown to be due and payable on such returns and all other taxes, assessments, governmental charges, or levies imposed on them or any of their properties, assets, income or franchises, to the extent such taxes and assessments have become due and payable and before they have become delinquent and all claims for which sums have become due and payable that have or might become a Lien on properties or assets of any Obligor or any other Subsidiary, provided that neither any Obligor nor any other Subsidiary need pay any such tax or assessment or claims if (i) the amount, applicability or validity thereof is contested by such Obligor or such Subsidiary on a timely basis in good faith and in appropriate proceedings, and an Obligor or another Subsidiary has established adequate reserves therefor in accordance with GAAP on its books or (ii) the nonpayment of all such taxes and assessments in the aggregate could not reasonably be expected to have a Material Adverse Effect.

12. REMEDIES ON DEFAULT, ETC.

12.1. Acceleration.

(a) If an Event of Default with respect to any Obligor described in paragraph (g) or (h) of Section 11 (other than an Event of Default described in clause (i) of paragraph (g) or described in clause (vi) of paragraph (g) by virtue of the fact that such clause encompasses clause (i) of paragraph (g)) has occurred, all the Notes then outstanding shall automatically become immediately due and payable.

(b) If any other Event of Default has occurred and is continuing, holders of at least 51% in principal amount of the Notes at the time outstanding may at any time at its or their option, by notice or notices to the Obligors, declare all the Notes then outstanding to be immediately due and payable.

(c) If any Event of Default described in paragraph (a) or (b) of Section 11 has occurred and is continuing, any holder or holders of Notes at the time outstanding affected by such Event of Default may at any time, at its or their option, by notice or notices to the Company, declare all the Notes held by it or them to be immediately due and payable.

Upon any Notes becoming due and payable under this Section 12.1, whether automatically or by declaration, such Notes will forthwith mature and the entire unpaid principal amount of such Notes, plus (w) all accrued and unpaid interest thereon and (x) any applicable Make-Whole Amount determined in respect of such principal amount (to the full extent permitted by applicable law), shall all be immediately due and payable, in each and every case without presentment, demand, protest or further notice, all of which are hereby waived. The Obligors acknowledge, and the parties hereto agree, that each holder of a Note has the right to

32

maintain its investment in the Notes free from repayment by the Obligors (except as herein specifically provided for) and that the provision for payment of a Make-Whole Amount by the Obligors in the event that the Notes are prepaid or are accelerated as a result of an Event of Default, is intended to provide compensation for the deprivation of such right under such circumstances.

12.2. Other Remedies.

If any Default or Event of Default has occurred and is continuing, and irrespective of whether any Notes have become or have been declared immediately due and payable under Section 12.1, the holder of any Note at the time outstanding may proceed to protect and enforce the rights of such holder by an action at law, suit in equity or other appropriate proceeding, whether for the specific performance of any agreement contained herein or in any Note, or for an injunction against a violation of any of the terms hereof or thereof, or in aid of the exercise of any power granted hereby or thereby or by law or otherwise.

12.3. Rescission.

At any time after any Notes have been declared due and payable pursuant to clause (b) or (c) of Section 12.1, the holders of at least 51% in principal amount of the Notes then outstanding, by written notice to the Obligors, may rescind and annul any such declaration and its consequences if (a) the Obligors have paid all overdue interest on the Notes, all principal of and any Make-Whole Amount on any Notes that are due and payable and are unpaid other than by reason of such declaration, and all interest on such overdue principal and any Make-Whole Amount and (to the extent permitted by applicable law) any overdue interest in respect of the Notes, at the Default Rate, (b) all Events of Default and Defaults, other than non-payment of amounts that have become due solely by reason of such declaration, have been cured or have been waived pursuant to Section 17, and (c) no judgment or decree has been entered for the payment of any monies due pursuant hereto or to the Notes. No rescission and annulment under this Section 12.3 will extend to or affect any subsequent Event of Default or Default or impair any right consequent thereon.

12.4. No Waivers or Election of Remedies, Expenses, etc.

No course of dealing and no delay on the part of any holder of any Note in exercising any right, power or remedy shall operate as a waiver thereof or otherwise prejudice such holder’s rights, powers or remedies. No right, power or remedy conferred by this Agreement or by any Note or the Subsidiary Guaranty upon any holder thereof shall be exclusive of any other right, power or remedy referred to herein or therein or now or hereafter available at law, in equity, by statute or otherwise. Without limiting the obligations of the Obligors under Section 15, the Obligors will pay to the holder of each Note on demand such further amount as shall be sufficient to cover all costs and expenses of such holder incurred in any enforcement or collection under this Section 12, including, without limitation, reasonable attorneys’ fees, expenses and disbursements.

34

(b) in the case of mutilation, upon surrender and cancellation thereof,

the Obligors at their own expense shall execute and deliver within five Business Days, in lieu thereof, a new Note of the same series, dated and bearing interest from the date to which interest shall have been paid on such lost, stolen, destroyed or mutilated Note or dated the date of such lost, stolen, destroyed or mutilated Note if no interest shall have been paid thereon.
