STERIS Corporation, an Ohio corporation (the “Company”), agrees with you as follows:

SECTION 1. AUTHORIZATION OF NOTES.

Section 1.1. Series A Notes. The Company will authorize the issuance and sale of (a) $40,000,000 aggregate principal amount of its 4.20% Senior Notes, Series A-1, due December 15, 2008 (the “Series A-1 Notes”), (b) $40,000,000 aggregate principal amount of its 5.25% Senior Notes, Series A-2, due December 15, 2013 (the “Series A-2 Notes”) and (c) $20,000,000 aggregate principal amount of its 5.38% Senior Notes, Series A-3, due December 15, 2015 (the “Series A-3 Notes”; the Series A-1 Notes, the Series A-2 Notes and the Series A-3 Notes are hereinafter referred to as the “Series A Notes”). The Series A Notes shall be substantially in the form set out in Exhibit 1-A, Exhibit 1-B and Exhibit 1-C, respectively, 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.

Section 1.2. Subsequent Series. Subsequent Series of promissory notes (collectively, the “Supplemental Notes”) may be issued pursuant to Supplemental Note Purchase Agreements as provided in Section 2.3 in an aggregate principal amount not to exceed $50,000,000 and: (a) shall be sequentially identified as “Series B Notes”, “Series C Notes”, “Series D Notes” et seq. and may consist of more than one different and separate tranches, but all such different and separate tranches of the same Series shall constitute one Series; (b) shall be in the aggregate principal amount of not less than $5,000,000 per each such series, (c) shall be dated the date of such Supplemental Note Purchase Agreement, (d) shall bear interest from such date at the rate per annum to be determined as of such date, (e) shall bear interest on overdue principal (including any overdue optional prepayment of principal) and premium, if any, and, to the extent permitted by law, on any overdue installment of interest at the stated rate plus 2%, (f) shall be

subject to required and optional prepayments, and (g) shall be expressed to mature on the stated maturity date, all as set forth in the Supplemental Note Purchase Agreement relating thereto and shall otherwise be substantially in the form attached hereto as Exhibit 1.2; provided, no Supplemental Notes shall be issued if at the time of issuance thereof and after giving effect to the application of proceeds therefor, any Default or Event of Default shall have occurred and be continuing. The Series A Notes, and the Supplemental Notes are herein sometimes collectively referred to as the “Notes.” As used herein, the term “Notes” shall include, without limitation, each Note delivered pursuant to this Agreement, the Other Agreements and any other Supplemental Note Purchase Agreement at the Closing and/or at any Supplemental Closing and each Note delivered in substitution or exchange for any such Note pursuant hereto.

SECTION 2. SALE AND PURCHASE OF NOTES; SUBSEQUENT SALES.

Section 2.1. Initial Sale of Notes. Subject to the terms and conditions of this Agreement, the Company will issue and sell to you and you will purchase from the Company, at the Closing provided for in Section 3, Series A Notes in the principal amount and of the tranche specified opposite your name in Schedule A at the purchase price of 100% of the principal amount thereof.

You and the Other Purchasers are herein sometimes collectively referred to as the “Initial Purchasers”. Your obligation hereunder, and the obligations of the Other Purchasers under the Other Agreements, are several and not joint obligations, and you shall have no obligation under any Other Agreement and no liability to any Person for the performance or nonperformance by any Other Purchaser thereunder. Without limiting the foregoing, the Company understands and agrees that your commitment and that of the Other Purchasers under the Other Agreements to purchase the Series A Notes as herein and therein contemplated does not constitute a commitment, obligation or indication of interest to purchase any Supplemental Notes.

The Pledge Agreements and any other instruments, documents, agreements related hereto pursuant to which the Company or any Subsidiary agrees to grant Liens in favor of the Collateral Agent for the ratable benefit of the Creditors are hereinafter referred to as the “Collateral Documents”. The Collateral Documents and the Subsidiary Guaranty are hereinafter collectively referred to as the “Security Documents.”

(c) The enforcement of the rights and benefits in respect of the Security Documents and the allocation of proceeds thereof will be subject to an intercreditor agreement dated as of December 17, 2003 entered into by the Agent on behalf of the Banks, the Collateral Agent and you, substantially in the form of Exhibit 2.2(c) attached hereto and made a part hereof (as the same may be further amended, supplemented or otherwise modified from time to time, the “Intercreditor Agreement”).

All such additional guaranties shall be given to the holders of the Notes pursuant to Section 9.7 of this Agreement.

(e) The holders of the Notes agree that the obligations of any Subsidiary under the Subsidiary Guaranty and the Liens of the Collateral Documents in respect of all or any part of the Collateral therein described shall be automatically released and discharged without the necessity of further action on the part of the holders of the Notes if, and to the extent, the corresponding guaranty or Lien given pursuant to the terms of the Bank Credit Agreement is released and discharged, provided that in the event the Company or any Subsidiary shall again become obligated under or with respect to the previously discharged Subsidiary Guaranty or again grant the discharged Lien, as the case may be, pursuant to the terms and provisions of the Subsidiary Guaranty, Pledge Agreement, the Bank Credit Agreement or any additional bank loan agreement entered into by the Company pursuant to which such lenders make available to the Company credit facilities which are pari passu with the Notes, then the Lien granted by the Company or its Subsidiaries under the Pledge Agreement or other Collateral Document or obligations of such Subsidiary under the Subsidiary Guaranty, as the case may be, shall be reinstated and any release thereof previously given shall be deemed null and void, and such Subsidiary Guaranty shall again benefit the holders of the Notes on an equal and pro rata basis

From and after such date, unless the Company 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 cancelled and shall not be reissued, and no Note shall be issued in lieu of any prepaid principal amount of any Note.

Section 8.5. Purchase of Notes. The Company will not and will not permit any Affiliate to purchase, redeem, prepay or otherwise acquire, directly or indirectly, any of the outstanding tranches of the Notes of any Series except (a) upon the payment or prepayment of each tranche of the Notes of such Series in accordance with the terms of this Agreement or the applicable Supplemental Note Purchase Agreement pursuant to which the Notes of such Series were issued or (b) pursuant to an offer to purchase made by the Company or an Affiliate pro rata to the holders of all Notes of such Series at the time outstanding upon the same terms and conditions. Any such offer shall provide each holder with sufficient information to enable it to make an informed decision with respect to such offer, and shall remain open for at least 15 Business Days. If the holders of more than 51% of the principal amount of the Notes of such Series then outstanding accept such offer, the Company shall promptly notify the remaining holders of such fact and the expiration date for the acceptance by holders of Notes of such Series of such offer shall be extended by the number of days necessary to give each such remaining holder at least 10 Business Days from its receipt of such notice to accept such offer. The Company will promptly cancel all Notes acquired by it or any Affiliate pursuant to any payment, prepayment or purchase of Notes pursuant to any provision of this Agreement or the applicable Supplemental Note Purchase Agreement and no Notes may be issued in substitution or exchange for any such Notes.

Section 8.6. 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 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

-20-


STERIS CORPORATION		NOTE PURCHASE AGREEMENT

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, 0.50% over the yield to maturity implied by (a) 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 “Page USD” of the Bloomberg Financial Markets Services Screen (or, if not available, any other national recognized trading screen reporting on-line intraday trading in the U.S. Treasury securities) for actively traded on-the-run U.S. Treasury securities having a maturity equal to the Remaining Average Life of such Called Principal as of such Settlement Date, or (b) if such yields are not reported as of such time or the yields reported as of such time are not ascertainable, 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 on-the-run 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 (i) converting U.S. Treasury bill quotations to bond-equivalent yields in accordance with accepted financial practice and (ii) interpolating linearly between (1) the actively traded on-the-run U.S. Treasury security with the maturity closest to and greater than the Remaining Average Life and (2) the actively traded on-the-run U.S. Treasury security with the maturity closest to and less than the Remaining Average Life.

“Remaining Average Life” means, with respect to any Called Principal, the number of years (calculated to the nearest one-twelfth year) obtained by dividing (a) such Called Principal into (b) the sum of the products obtained by multiplying (i) the principal component of each Remaining Scheduled Payment with respect to such Called Principal by (ii) 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 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 or has become or is declared to be immediately due and payable pursuant to Section 12.1, as the context requires.
