Item 1.01

Entry into a Material Definitive Agreement

On May 15, 2015, STERIS Corporation (the “Company” or “STERIS”) entered into a Note Purchase Agreement with various institutional investors (the “Note Purchase Agreement”), providing for the private issuance and sale on the same date by the Company of $350 million in aggregate principal amount of the Company’s Series A Senior Notes (the “Senior Notes”). The Company’s obligations under the Note Purchase Agreement and the Senior Notes are unsecured but guaranteed by certain of the Company’s domestic subsidiaries pursuant to an Affiliate Guaranty. The net proceeds of the sales will be used to repay debt and for other corporate purposes. On May 15, 2015, the Company repaid all outstanding debt under its bank credit facility. A total of $690 million of fixed rate debt of the Company was outstanding after giving effect to the sale of the Senior Notes.

The Senior Notes have maturities of 10, 12 and 15 years. Details are as follows:


Series	Aggregate Principal Amount		Interest Rate			Maturity Date
A-1	$	125 million		3.45	%	5/14/25
A-2	$	125 million		3.55	%	5/14/27
A-3	$	100 million		3.70	%	5/14/30

The weighted average maturity and interest rates of the Senior Notes are approximately 12.1 years and 3.56% respectively. The Senior Notes are payable in full together with accrued and unpaid interest at their specified maturities or are payable in whole or in part on such earlier dates as may be required or permitted by the terms of the Note Purchase Agreement. Interest on the Senior Notes accrues from May 15, 2015 and is payable in arrears, beginning in November, 2015 and every 6 months thereafter. Depending on the circumstances, a prepayment penalty may be payable for prepayments made prior to stated maturity.

The Note Purchase Agreement contains customary representations and warranties and covenants, including restrictions on liens, limitations on dispositions, leverage limitations and interest coverage requirements. The Note Purchase Agreement also contains customary events of default, which include payment and other covenant defaults, breaches of representations and warranties, certain defaults in respect of other material indebtedness and certain ERISA defaults or failures to pay money judgments. Upon the occurrence of any of these events the Company’s payment obligations under the Senior Notes could be accelerated.

As a result of the execution of the Note Purchase Agreement and issuance of the Senior Notes, under the terms of the Amended and Restated 364-Day Bridge Credit Agreement (“Bridge Agreement”) dated March 31, 2015 of the Company and New STERIS Limited with Bank of America, N.A. as administrative agent and the lenders party thereto, the commitments of the Bridge Agreement lenders were reduced by $297.45 million. This resulted in new Bridge Agreement commitments of $232.55 million and £340 million.

A number of the Senior Note purchasers also hold notes issued by the Company in 2003, 2008 and 2012-13 private placements.

The above summary of certain terms and conditions of the Note Purchase Agreement does not purport to be a complete discussion of that agreement or related documents and is qualified in its entirety by reference to the Note Purchase Agreement, a copy of which is attached to this report as Exhibit 10.1. Capitalized terms used above and not defined herein have the meanings given under the Note Purchase Agreement.

The Note Purchase Agreement and Affiliate Guaranty attached to this report and the above description have been included to provide investors and security holders with information regarding the terms of such documents. They are not intended to provide any other factual information about the Company or its respective subsidiaries or affiliates or equity holders. The representations, warranties and covenants contained in such documents were made only for purposes of those agreements and as of specific dates; were solely for the benefit of the parties to such documents, as applicable; and may be subject to limitations agreed upon by the parties, including being qualified by confidential disclosures made by each contracting party to the other for the purposes of allocating contractual risk between them that differ from those applicable to investors. Investors should be aware that the representations,

warranties and covenants or any description thereof may not reflect the actual state of facts or condition of the Company or any of its respective subsidiaries, affiliates, businesses, or equity holders. Moreover, information concerning the subject matter of the representations, warranties and covenants may change after the date of such documents, as applicable, which subsequent information may or may not be fully reflected in public disclosures by the Company. Accordingly, investors should read the representations and warranties in such documents not in isolation but only in conjunction with the other information about the Company that it includes in reports, statements and other filings it makes with the U.S. Securities and Exchange Commission.

Disclosure requirements of the UK Takeover Code

Under Rule 8.3(a) of the Code, any person who is interested in 1% or more of any class of relevant securities of an offeree company or of any securities exchange offeror (being any offeror other than an offeror in respect of which it has been announced that its offer is, or is likely to be, solely in cash) must make an Opening Position Disclosure following the commencement of the offer period and, if later, following the announcement in which any securities exchange offeror is first identified. An Opening Position Disclosure must contain details of the person’s interests and short positions in, and rights to subscribe for, any relevant securities of each of (i) the offeree company and (ii) any securities exchange offeror(s). An Opening Position Disclosure by a person to whom Rule 8.3(a) applies must be made by no later than 3.30 pm (London time) on the 10th business day following the commencement of the offer period and, if appropriate, by no later than 3.30 pm (London time) on the 10th business day following the announcement in which any securities exchange offeror is first identified. Relevant persons who deal in the relevant securities of the offeree company or of a securities exchange offeror prior to the deadline for making an Opening Position Disclosure must instead make a Dealing Disclosure.

Under Rule 8.3(b) of the Code, any person who is, or becomes, interested in 1% or more of any class of relevant securities of the offeree company or of any securities exchange offeror must make a Dealing Disclosure if the person deals in any relevant securities of the offeree company or of any securities exchange offeror. A Dealing Disclosure must contain details of the dealing concerned and of the person’s interests and short positions in, and rights to subscribe for, any relevant securities of each of (i) the offeree company and (ii) any securities exchange offeror, save to the extent that these details have previously been disclosed under Rule 8. A Dealing Disclosure by a person to whom Rule 8.3(b) applies must be made by no later than 3.30 pm (London time) on the business day following the date of the relevant dealing.

If two or more persons act together pursuant to an agreement or understanding, whether formal or informal, to acquire or control an interest in relevant securities of an offeree company or a securities exchange offeror, they will be deemed to be a single person for the purpose of Rule 8.3.

Opening Position Disclosures must also be made by the offeree company and by any offeror and Dealing Disclosures must also be made by the offeree company, by any offeror and by any persons acting in concert with any of them (see Rules 8.1, 8.2 and 8.4).

Details of the offeree and offeror companies in respect of whose relevant securities Opening Position Disclosures and Dealing Disclosures must be made can be found in the Disclosure Table on the Takeover Panel’s website at www.thetakeoverpanel.org.uk, including details of the number of relevant securities in issue, when the offer period commenced and when any offeror was first identified. You should contact the Panel’s Market Surveillance Unit on +44 (0)20 7638 0129 if you are in any doubt as to whether you are required to make an Opening Position Disclosure or a Dealing Disclosure.

No Offer or Solicitation

This communication is provided for informational purposes only and does not constitute an offer to sell, or an invitation to subscribe for, purchase or exchange, any securities or the solicitation of any vote or approval in any jurisdiction, nor shall there be any sale, issuance, exchange or transfer of the securities referred to in this communication in any jurisdiction in contravention of applicable law.

Forward-Looking Statements

This communication may contain statements concerning certain trends, expectations, forecasts, estimates, or other forward-looking information affecting or relating to Synergy or STERIS or its industry, products or activities that are intended to qualify for the protections afforded “forward-looking statements” under the Private Securities Litigation Reform Act of 1995 and other laws and regulations. Forward-looking statements speak only as to the date of this communication and may be identified by the use of forward- looking terms such as “may,” “will,” “expects,” “believes,” “anticipates,” “plans,” “estimates,” “projects,” “targets,” “forecasts,” “outlook,” “impact,” “potential,” “confidence,” “improve,” “optimistic,” “deliver,” “comfortable,” “trend”, and “seeks,” or the negative of such terms or other variations on such terms or comparable terminology. Many important factors could cause actual results to differ materially from those in the forward-looking statements including, without limitation, disruption of production or supplies, changes in market conditions, political events, pending or future claims or litigation, competitive factors, technology advances, actions of regulatory agencies, and changes in laws, government regulations, labeling or product approvals or the application or interpretation thereof. Other risk factors are described herein and in STERIS and Synergy’s other securities filings, including Item 1A of STERIS’s Annual Report on Form 10-K for the year ended March 31, 2014 dated May 29, 2014 and in Synergy’s annual report and accounts for the year ended 30 March 2014 (section headed “principal risks and uncertainties”). Many of these important factors are outside of STERIS’s or Synergy’s control. No assurances can be provided as to any result or the timing of any outcome regarding matters described in the communication or otherwise with respect to any regulatory action, administrative proceedings, government investigations, litigation, warning letters, consent decree, cost reductions, business strategies, earnings or revenue trends or future financial results. References to products and the consent decree are summaries only and should not be considered the specific terms of the decree or product clearance or literature. Unless legally required, STERIS and Synergy do not undertake to update or revise any forward-looking statements even if events make clear that any projected results, express or implied, will not be realized. Other potential risks and uncertainties that could cause actual results to differ materially from those in the

forward-looking statements include, without limitation, (a) the receipt of approval of both STERIS’s shareholders and Synergy’s shareholders, (b) the regulatory approvals required for the transaction not being obtained on the terms expected or on the anticipated schedule, (c) the parties’ ability to meet expectations regarding the timing, completion and accounting and tax treatments of the transaction, (d) the possibility that the parties may be unable to achieve expected synergies and operating efficiencies in connection with the transaction within the expected time-frames or at all and to successfully integrate Synergy’s operations into those of STERIS, (e) the integration of Synergy’s operations into those of STERIS being more difficult, time-consuming or costly than expected, (f) operating costs, customer loss and business disruption (including, without limitation, difficulties in maintaining relationships with employees, customers, clients or suppliers) being greater than expected following the transaction, (g) the retention of certain key employees of Synergy being difficult, (h) changes in tax laws or interpretations that could increase our consolidated tax liabilities, including, if the transaction is consummated, changes in tax laws that would result in New STERIS being treated as a domestic corporation for United States federal tax purposes, (i) the potential for increased pressure on pricing or costs that leads to erosion of profit margins, (j) the possibility that market demand will not develop for new technologies, products or applications or services, or business initiatives will take longer, cost more or produce lower benefits than anticipated, (k) the possibility that application of or compliance with laws, court rulings, certifications, regulations, regulatory actions, including without limitation those relating to FDA warning notices or letters, government investigations, the outcome of any pending FDA requests, inspections or submissions, or other requirements or standards may delay, limit or prevent new product introductions, affect the production and marketing of existing products or services or otherwise affect STERIS’s or Synergy’s performance, results, prospects or value, (l) the potential of international unrest, economic downturn or effects of currencies, tax assessments, adjustments or anticipated rates, raw material costs or availability, benefit or retirement plan costs, or other regulatory compliance costs, (m) the possibility of reduced demand, or reductions in the rate of growth in demand, for STERIS’s or Synergy’s products and services, (n) the possibility that anticipated growth, cost savings, new product acceptance, performance or approvals, or other results may not be achieved, or that transition, labor, competition, timing, execution, regulatory, governmental, or other issues or risks associated with STERIS and Synergy’s businesses, industry or initiatives including, without limitation, the consent decree or those matters described in STERIS’s Form 10-K for the year ended March 31, 2014 and other securities filings, may adversely impact STERIS’s or Synergy’s performance, results, prospects or value, (o) the possibility that anticipated financial results or benefits of recent acquisitions, or of STERIS’s restructuring efforts will not be realized or will be other than anticipated, (p) the effects of the contractions in credit availability, as well as the ability of STERIS’s and Synergy’s customers and suppliers to adequately access the credit markets when needed, and (q) those risks described in STERIS’s Annual Report on Form 10-K for the year ended March 31, 2014, and other securities filings.

Important Additional Information Regarding the Transaction Will Be Filed With the SEC

Following its conversion to a public limited company, it is expected that the shares of New STERIS to be issued to Synergy Shareholders in the English law scheme of arrangement transaction that forms a part of the transaction will be issued in reliance upon the exemption from the registration requirements of the Securities Act of 1933, as amended, provided by Section 3(a)(10) thereof.

In connection with the issuance of New STERIS shares to STERIS shareholders pursuant to the merger that forms a part of the transaction, New STERIS has filed with the SEC a Registration Statement on Form S-4, which was declared effective on February 6, 2014, that contains a proxy statement of STERIS as well as a prospectus of New STERIS relating to the merger that forms a part of the transaction, which we refer to together as the Proxy Statement/Prospectus.

INVESTORS AND SECURITY HOLDERS ARE URGED TO READ THE PROXY STATEMENT/PROSPECTUS, AND OTHER DOCUMENTS FILED WITH THE SEC IN CONNECTION WITH THE TRANSACTION CAREFULLY AND IN THEIR ENTIRETY, BECAUSE THEY CONTAIN IMPORTANT INFORMATION ABOUT THE TRANSACTION, THE PARTIES TO THE TRANSACTION AND THE RISKS ASSOCIATED WITH THE TRANSACTION. Those documents, as well as STERIS’s and New STERIS’s other public filings with the SEC may be obtained without charge at the SEC’s website at www.sec.gov, at STERIS’s

website at www.steris-ir.com. Security holders and other interested parties may obtain, without charge, a copy of the Proxy Statement/Prospectus and other relevant documents (when available) by directing a request by mail or telephone [email protected] or (440) 392-7245. Security holders may also read and copy any reports, statements and other information filed with the SEC at the SEC public reference room at 100 F Street N.E., Room 1580, Washington, D.C. 20549. Please call the SEC at (800) 732-0330 or visit the SEC’s website for further information on its public reference room.

STERIS, its directors and certain of its executive officers may be considered participants in the solicitation of proxies in connection with the transactions contemplated by the Proxy Statement/Prospectus. Information about the directors and executive officers of STERIS is set forth in its Annual Report on Form 10-K for the year ended March 31, 2014, which was filed with the SEC on May 29, 2014, and its proxy statement for its 2014 annual meeting of shareholders, which was filed with the SEC on June 9, 2014. Other information regarding potential participants in the proxy solicitations and a description of their direct and indirect interests, by security holdings or otherwise, is contained in the Proxy Statement/Prospectus.

Synergy and New STERIS are each organized under the laws of England and Wales. Some of the officers and directors of Synergy and New STERIS are residents of countries other than the United States. As a result, it may not be possible to sue Synergy, New STERIS or such persons in a non-US court for violations of US securities laws. It may be difficult to compel Synergy, New STERIS and their respective affiliates to subject themselves to the jurisdiction and judgment of a US court or for investors to enforce against them the judgments of US courts.

PREPAYMENT OF THE NOTES.

Section 8.1. Required Prepayments. No regularly scheduled prepayment of the principal of any tranche of the Series A Notes is required prior to the final maturity thereof.

(a) The Company may, at its option, upon notice as provided below, prepay at any time all, or from time to time any part of, any Series of the Notes, in an amount not less than 10% of the aggregate principal amount of such Series of the Notes then outstanding (but if in the case of a partial prepayment, then against each tranche within such Series of Notes in proportion to the aggregate principal amount outstanding of each tranche of such Series), at 100% of the principal amount so prepaid, together with interest accrued thereon to the date of such prepayment, plus the Make-Whole Amount determined for the prepayment date with respect to such principal amount. The Company will give each holder of the Series of Notes to be prepaid written notice of each optional prepayment under this Section 8.2 not less than 10 days and not more than 60 days prior to the date fixed for such prepayment. Each such notice shall specify such date, the aggregate principal amount of the Series of the Notes to be prepaid on such date, the principal amount of each Note held by such holder to be prepaid (determined in accordance with Section 8.3), and the interest to be paid on the prepayment date with respect to such principal amount being prepaid, and shall be accompanied by a certificate of a Senior Financial Officer as to the estimated Make-Whole Amount due in connection with such prepayment (calculated as if the date of such notice were the date of the prepayment), setting forth the details of such computation. Two Business Days prior to such prepayment, the Company shall deliver to each holder of the Series of Notes to be prepaid a certificate of a Senior Financial Officer specifying the calculation of such Make-Whole Amount as of the specified prepayment date.

(b) Notwithstanding anything contained in this Section 8.2 to the contrary, if and so long as any Default or Event of Default shall have occurred and be continuing, any prepayment of the Notes pursuant to the provisions of Section 8.2(a) shall be allocated among all of the Notes of all Series at the time outstanding in proportion, as nearly as practicable, to the respective unpaid principal amounts thereof.

Section 8.3. Allocation of Partial Prepayments. In the case of any partial prepayment of the Notes of any Series pursuant to Section 8.2, the principal amount of the Notes of such Series to be prepaid shall be allocated among each tranche of the Notes of such Series at the time outstanding in proportion, as nearly as practicable, to the respective unpaid principal amounts of each tranche of the Notes of such Series not theretofore called for prepayment.

Section 8.4. Maturity; Surrender, Etc.

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 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 ask-side 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 PX1” of the Bloomberg Financial Markets Services Screen (or, if not available, any other nationally recognized trading screen reporting on-line intraday trading in the

-21-


STERIS CORPORATION		NOTE PURCHASE AGREEMENT

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 (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 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.

Section 8.7. Change in Control.

(a) Notice of Change in Control or Control Event. Subject to compliance with applicable law and other Company obligations, the Company will, within five Business Days after any Responsible Officer has knowledge of the occurrence of any Change in Control or Control Event, give written notice of such Change in Control or Control Event to each holder of Notes unless notice in respect of such Change in Control (or the Change in Control contemplated

(c) Offer to Prepay Notes. The offer to prepay Notes contemplated by subparagraphs (a) and (b) of this Section 8.7 shall be an offer to prepay, in accordance with and subject to this Section 8.7, all, but not less than all, of the Notes held by each holder (in this case only, “holder” in respect of any Note registered in the name of a nominee for a disclosed beneficial owner shall mean such beneficial owner) on a date specified in such offer (the “Proposed Prepayment Date”).

The Reporting Entity will, and will cause its Restricted Subsidiaries to, conduct all material transactions otherwise permitted under this Agreement with any of their Affiliates (excluding the members of the Consolidated Group) on terms that are fair and reasonable and no less favorable to the Reporting Entity or such Restricted Subsidiary than it would obtain in a comparable arm’s-length transaction with a Person not an Affiliate; provided that the restrictions of this Section 9.10 shall not apply to the following:

(a) the payment of dividends or other distributions (whether in cash, securities or other property) with respect to any Equity Interests in a member of the Consolidated Group, or any payment (whether in cash, securities or other property), including any sinking fund or similar deposit, on account of the purchase, redemption, retirement, acquisition, cancellation or termination of any such Equity Interests in such Person or any option, warrant or other right to acquire any such Equity Interests in such Person;

Section 12.1. Acceleration. (a) If an Event of Default with respect to the Reporting Entity or the Company (if the Company is not the Reporting Entity) 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.

The Company acknowledges, and the parties hereto agree, that each holder of a Note has the right to maintain its investment in the Notes free from repayment by the Company (except as herein specifically provided for), and that the provision for payment of a Make-Whole Amount by the Company 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.

Section 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, in any Note or in any Security Document, 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.

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.

Section 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, by any Note or by any Security Document 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.

Notices and other communications sent electronically shall be deemed received on the day such notices or other communications are sent unless such notice or other communication is not sent during the normal business hours of the recipient, in which case such notice or communication shall be deemed to have been sent at the opening of business on the next business day.

SECTION 19.

REPRODUCTION OF DOCUMENTS.

This Agreement (including any Supplemental Note Purchase Agreement and any Security Document) and all documents relating thereto, including, without limitation, (a) consents, waivers and modifications that may hereafter be executed, (b) documents received by any Purchaser at the Closing (except the Notes themselves), and (c) financial statements, certificates and other information previously or hereafter furnished to any Purchaser, may be reproduced by such Purchaser by any photographic, photostatic, microfilm, microcard, miniature photographic or other similar process and such Purchaser may destroy any original document so reproduced. The Company agrees and stipulates for itself and on behalf of the Reporting Entity that, to the extent permitted by applicable law, any such reproduction shall be admissible in evidence as the original itself in any judicial or administrative proceeding (whether or not the original is in existence and whether or not such reproduction was made by such Purchaser in the regular course of business) and any enlargement, facsimile or further reproduction of such reproduction shall likewise be admissible in evidence. This Section 19 shall not prohibit the Company or any other holder of Notes from contesting any such reproduction to the same extent that it could contest the original, or from introducing evidence to demonstrate the inaccuracy of any such reproduction.

SECTION 20.

CONFIDENTIAL INFORMATION.

For the purposes of this Section 20, “Confidential Information” means information delivered to any Purchaser by or on behalf of the Reporting Entity or any Subsidiary in connection with the transactions contemplated by or otherwise pursuant to this Agreement that is confidential and/or proprietary in nature and that was clearly marked or labeled or otherwise adequately identified in writing (or verbally in the case of oral communication) when received by such Purchaser as being confidential information of the Reporting Entity or such Subsidiary; provided that such term does not include information that (a) was publicly known or otherwise known to such Purchaser prior to the time of such disclosure, (b) subsequently becomes publicly known through no act or omission by such Purchaser or any Person acting on its behalf,

-47-


STERIS CORPORATION		NOTE PURCHASE AGREEMENT

(c) otherwise becomes known to such Purchaser other than through disclosure by the Reporting Entity or any Subsidiary or any other holder of any Note, (d) constitutes financial statements delivered to such Purchaser under Section 7.1 that are otherwise publicly available or (e) relates to the “tax treatment” or “tax structure” of the transactions contemplated by this Agreement, as such terms are defined in Section 1.6011-4 of the Treasury Department regulations issued under the Code, and all materials of any kind that are provided to such Purchaser relating to such tax treatment or tax structure, except to the extent that disclosure of such information is not permitted under any applicable securities laws, and except with respect to any item that contains information concerning the tax treatment or tax structure of a transaction as well as Confidential Information, this clause (e) shall only apply to that portion of the item relating to tax treatment or tax structure. Each Purchaser will maintain the confidentiality of such Confidential Information in accordance with reasonable procedures adopted by it in good faith to protect confidential information of third parties delivered to it; provided that such Purchaser may deliver or disclose Confidential Information to (i) its directors, trustees, officers, employees, agents, attorneys and Affiliates (which Affiliates have agreed to hold confidential the confidential information) (to the extent such disclosure reasonably relates to the administration of the investment represented by its Notes), (ii) its financial advisors and other professional advisors who agree to hold confidential the Confidential Information substantially in accordance with the terms of this Section 20, (iii) any other holder of any Note, (iv) any Institutional Investor to which it sells or offers to sell such Note or any part thereof or any participation therein (if such Person has agreed in writing prior to its receipt of such Confidential Information to be bound by the provisions of this Section 20, and such written agreement shall name the Company as a third party beneficiary thereof), (v) any Person from which it offers to purchase any security of the Reporting Entity (if such Person has agreed in writing prior to its receipt of such Confidential Information to be bound by the provisions of this Section 20), (vi) any federal or state regulatory authority having jurisdiction over it to the extent required or requested, (vii) the National Association of Insurance Commissioners or any similar organization, or any nationally recognized rating agency that requires access to information about its investment portfolio to the extent required or requested, or (viii) any other Person to which such delivery or disclosure may be required (w) to effect compliance with any law, rule, regulation or order applicable to such Purchaser, (x) in response to any subpoena or other legal process, (y) in connection with any litigation to which such Purchaser is a party or (z) if an Event of Default has occurred and is continuing, to the extent it may reasonably determine such delivery and disclosure to be necessary or appropriate in the enforcement or for the protection of the rights and remedies under its Notes and this Agreement. Each holder of a Note, by its acceptance of a Note, will be deemed to have agreed to be bound by and to be entitled to the benefits of this Section 20 as though it were a party to this Agreement. On reasonable request by the Company in connection with the delivery to any holder of a Note of information required to be delivered to such holder under this Agreement or requested by such holder (other than a holder that is a party to this Agreement or its nominee or any other holder that has previously delivered such confirmation), such holder will enter into an agreement with the Company confirming in writing that it is bound by the provisions of this Section 20.

SECTION 21.

SUBSTITUTION OF PURCHASER.

Each Purchaser shall have the right to substitute any one of its Affiliates as the purchaser of the Notes that it has agreed to purchase hereunder, by written notice to the Company, which

-48-


STERIS CORPORATION		NOTE PURCHASE AGREEMENT

notice shall be signed by both such Purchaser and such Affiliate, shall contain such Affiliate’s agreement to be bound by this Agreement and shall contain a confirmation by such Affiliate of the accuracy with respect to it of the representations set forth in Section 6. Upon receipt of such notice, any reference to such Purchaser in this Agreement (other than in this Section 21), shall be deemed to refer to such Affiliate in lieu of such original Purchaser. In the event that such Affiliate is so substituted as a Purchaser hereunder and such Affiliate thereafter transfers to such original Purchaser all of the Notes then held by such Affiliate, upon receipt by the Company of notice of such transfer, any reference to such Affiliate as a “Purchaser” in this Agreement (other than in this Section 21), shall no longer be deemed to refer to such Affiliate, but shall refer to such original Purchaser, and such original Purchaser shall again have all the rights of an original holder of the Notes under this Agreement.

SECTION 22.

MISCELLANEOUS.

Section 22.1. Successors and Assigns. All covenants and other agreements contained in this Agreement (including any Supplemental Note Purchase Agreement) by or on behalf of any of the parties hereto bind and inure to the benefit of their respective successors and assigns (including, without limitation, any subsequent holder of a Note) whether so expressed or not.

Section 22.2. Payments Due on Non-Business Days. Anything in this Agreement or the Notes to the contrary notwithstanding, any payment of principal of or Make-Whole Amount or interest on any Note that is due on a date other than a Business Day shall be made on the next succeeding Business Day without including the additional days elapsed in the computation of the interest payable on such next succeeding Business Day.

Section 22.3. Severability. Any provision of this Agreement that is prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof, and any such prohibition or unenforceability in any jurisdiction shall (to the full extent permitted by law) not invalidate or render unenforceable such provision in any other jurisdiction.

Section 22.4. Construction. Each covenant contained herein shall be construed (absent express provision to the contrary) as being independent of each other covenant contained herein, so that compliance with any one covenant shall not (absent such an express contrary provision) be deemed to excuse compliance with any other covenant. Where any provision herein refers to action to be taken by any Person, or which such Person is prohibited from taking, such provision shall be applicable whether such action is taken directly or indirectly by such Person.

Where the character or amount of any asset or liability or item of income or expense is required to be determined or any consolidation or other accounting computation is required to be made by the Reporting Entity for the purposes of this Agreement, the same shall be done by the Reporting Entity in accordance with GAAP, to the extent applicable, except where such principles are inconsistent with the requirements of this Agreement.

For purposes of determining compliance with this Agreement (including, without limitation, Section 9, Section 10 and the definition of “Debt”), any election by the Reporting

-49-


STERIS CORPORATION		NOTE PURCHASE AGREEMENT

Entity or any Restricted Subsidiary to measure any financial liability using fair value (as permitted by Financial Accounting Standards Board Accounting Standards Codification Topic No. 825-10-25 – Fair Value Option, International Accounting Standard 39 – Financial Instruments: Recognition and Measurement or any similar accounting standard) shall be disregarded and such determination shall be made as if such election had not been made.

Notwithstanding the foregoing, if there is a change in GAAP after the date of this Agreement, the result of which is to cause the Reporting Entity to be in default in respect of any covenant contained in Section 10, then such default shall be stayed and no Default or Event of Default shall occur hereunder. The Reporting Entity shall then, in consultation with its independent accountants, negotiate in good faith with the holders of Notes for a period of 60 days to make any necessary adjustments to such covenant or any component of financial computations used to calculate such covenant to provide the holders of the Notes with substantially the same protection as such covenant provided prior to the relevant change in GAAP. In the event that no agreement is reached by the end of such 60-day negotiation period, then, at the Reporting Entity’s election, the Reporting Entity’s compliance with such covenant shall be determined on the basis of GAAP in effect immediately prior to such change and each subsequent set of financial statements delivered to holders of Notes pursuant to Section 7.1(a) or (b) shall include detailed reconciliations reasonably satisfactory to the Required Holders as to the effect of such change in GAAP.

Section 22.5. Counterparts. This Agreement may be executed in any number of counterparts, each of which shall be an original but all of which together shall constitute one instrument. Each counterpart may consist of a number of copies hereof, each signed by less than all, but together signed by all, of the parties hereto.

Section 22.6. Governing Law. This Agreement shall be construed and enforced in accordance with, and the rights of the parties shall be governed by, the law of the State of New York, excluding choice-of-law principles of the law of such State that would require the application of the laws of a jurisdiction other than such State.

Section 22.7. Submission to Jurisdiction; Waiver of Jury Trial. (a) The Reporting Entity and the Company hereby irrevocably submit and consent to the jurisdiction of the federal court located within the County of New York, State of New York (or if such court lacks jurisdiction, the State courts located therein), and irrevocably agrees that all actions or proceedings relating to this Agreement and the Notes may be litigated in such courts, and each of the Reporting Entity and the Company waives any objection which it may have based on improper venue or forum non conveniens to the conduct of any proceeding in any such court and waives personal service of any and all process upon it, and consents that all such service of process be made by delivery to it at the address of such Person set forth in Section 18 above or to its agent referred to below at such agent’s address set forth below (with a courtesy copy to the Reporting Entity and the Company at the address set forth in Section 18) and that service so made shall be deemed to be completed upon actual receipt. Nothing contained in this section shall affect the right of any holder of Notes to serve legal process in any other manner permitted by law or to bring any action or proceeding in the courts of any jurisdiction against the Company or the Reporting Entity or to enforce a judgment obtained in the courts of any other jurisdiction.

(b) The parties hereto waive any right to have a jury participate in resolving any dispute, whether sounding in contract, tort, or otherwise, between them arising out of, connected with, related to or incidental to the relationship established between them in connection with this Agreement and the Notes, any financing agreement, any loan party document or any other instrument, document or agreement executed or delivered in connection herewith or the transactions related hereto. The parties hereto hereby agree and consent that any such claim, demand, action or cause of action shall be decided by court trial without a jury and that any of them may file an original counterpart or a copy of this Agreement with any court as written evidence of the consent of the parties hereto to the waiver of their right to trial by jury.

SECTION 23.

TAX INDEMNIFICATION; PAYMENT IN U.S. DOLLARS.

In the event, in accordance with Section 10.4, the entity which results from the consolidation or merger described therein or the Person to whom the Company has sold or otherwise disposed of all or substantially all of its assets is organized under the laws of any jurisdiction other than any state of the United States or the District of Columbia the following shall apply:

(a) Each payment by the Company (or applicable successor in accordance with Section 10.4) shall be made, under all circumstances, without setoff, counterclaim or reduction for, and free from and clear of, and without deduction for or because of, any and all present or future taxes, levies, imposts, duties, fees, charges, deductions, withholding, restrictions or conditions of any nature whatsoever (hereinafter called “Relevant Taxes”) imposed, levied, collected, assessed, deducted or withheld by the government of any country or jurisdiction (or any authority therein or thereof), other than the United States of America or any political subdivision or authority therein or thereof, from or through which payments hereunder or on or in respect of the Notes are actually made (each a “Taxing Jurisdiction”), unless such imposition, levy, collection, assessment, deduction, withholding or other restriction or condition is required by law. If the Company is required by law to make any payment under this Agreement or the Notes subject to such deduction, withholding or other restriction or condition, then the Company shall forthwith (i) pay over to the government or taxing authority imposing such tax the full amount required to be deducted, withheld from or otherwise paid by the Company (including the full amount required to be deducted or withheld from or otherwise paid by the Company in respect of the Tax Indemnity Amounts (as defined below)); (ii) pay each Holder such additional amounts (“Tax Indemnity Amounts”) as may be necessary in order that the net amount of every payment made to each Holder, after provision for payment of such Relevant Taxes (including any required deduction, withholding or other payment of tax on or with respect to such Tax Indemnity Amounts), shall be equal to the amount which such holder would have received had there been no imposition, levy, collection, assessment, deduction, withholding or other restriction or condition. Notwithstanding the foregoing provisions of this Section 23(a), no such Tax Indemnity Amounts shall be payable for or on account of any tax, assessment or other governmental charge that is imposed or withheld by reason of the failure of the holder of a Note to complete, execute, update and deliver to the Company any form or document to the extent applicable to such holder that may be required by law or by reason of

-51-


STERIS CORPORATION		NOTE PURCHASE AGREEMENT

administration of such law and which is reasonably requested in writing to be delivered by the Company in order to enable the Company to make payments pursuant to this Section 23(a) without deduction or withholding for taxes, assessments or governmental charges, or with deduction or withholding of such lesser amount, which form or document shall be delivered within one hundred twenty days of a written request therefor by the Company. If in connection with the payment of any such Tax Indemnity Amounts, any holder of a Note that is a United States person within the meaning of the Code or a foreign person engaged in a trade or business within the United States of America, incurs taxes imposed by the United States of America or any political subdivision or taxing authority therein (“United States Taxes”) on such Tax Indemnity Amounts, the Company shall pay to such holder such further amount as will insure that the net expenditure of the holder for United States Taxes due to receipt of such Tax Indemnity Amounts (after taking into account any withholding, deduction, tax credit or tax benefit in respect of such further amount or any Tax Indemnity Amount) is no greater than it would have been had no Tax Indemnity Amounts been paid to the holder.

(b) Any payment made by the Company to any holder of a Note for the account of any such holder in respect of any amount payable by the Company shall be made in the lawful currency of the United States of America (“U.S. Dollars”). Any amount received or recovered by such holder other than in U.S. Dollars (whether as a result of, or of the enforcement of, a judgment or order of any court, or in the liquidation or dissolution of the Company or otherwise) in respect of any such sum expressed to be due hereunder or under the Notes shall constitute a discharge of the Company only to the extent of the amount of U.S. Dollars which such holder is able, in accordance with normal banking procedures, to purchase with the amount so received or recovered in that other currency on the date of the receipt or recovery (or, if it is not practicable to make that purchase on such date, on the first date on which it is practicable to do so). If the amount of U.S. Dollars so purchased is less than the amount of U.S. Dollars expressed to be due hereunder or under the Notes, the Company agrees as a separate and independent obligation from the other obligations herein, notwithstanding any such judgment, to indemnify the holder against the loss. If the amount of U.S. Dollars so purchased exceeds the amount of U.S. Dollars expressed to be due hereunder or under the Notes, then such holder agrees to remit such excess to the Company.

Any Holder may, at its option, proceed hereunder against any Guarantor in the first instance to collect monies when due, the payment of which is guaranteed hereby, without first proceeding against the Company or any other Person and without first resorting to any direct or indirect security for the Notes or for this Guaranty or any other remedy. The liability of each Guarantor hereunder shall in no way be affected or impaired by any acceptance by any Holder of any direct or indirect security for, or other guaranties of, any Debt, liability or obligation of the Company or any other Person to any Holder or by any failure, delay, neglect or omission by any Holder to realize upon or protect any such guaranties, Debt, liability or obligation or any notes or other instruments evidencing the same or any direct or indirect security therefor or by any approval, consent, waiver, or other action taken, or omitted to be taken by any such Holder.

(c) Subject to Section 13 hereof, the obligations of the Guarantors hereunder shall be binding upon the Guarantors and their successors and assigns, and shall remain in full force and effect until the entire principal, interest and Make-Whole Amount, if any, on the Notes and all other sums due pursuant to Section 2 shall have been paid and such obligations shall not be affected, modified or impaired upon the happening from time to time of any event, including without limitation any of the following, whether or not with notice to or the consent of the Guarantors:

(12) any defense whatsoever that: (i) the Company or any other Person might have to the payment of the Notes (principal, Make-Whole Amount, if any, or interest), other than payment thereof in Federal or other immediately available funds, or (ii) the Company or any other Person might have to the performance or observance of any of the provisions of the Notes, the Note Purchase Agreement or any other agreement, whether through the satisfaction or purported satisfaction by the Company, any other Guarantor or any other Person of its debts due to any cause such as bankruptcy, insolvency, receivership, merger, consolidation, reorganization, dissolution, liquidation, winding-up or otherwise, other than the defense of indefeasible payment in full in cash of the Notes; or

(13) any act or failure to act with regard to the Notes, the Note Purchase Agreement, this Guaranty or any other agreement or anything which might vary the risk of any Guarantor or any other Person; or

E-2.2(a)-8

provided that the specific enumeration of the above-mentioned acts, failures or omissions shall not be deemed to exclude any other acts, failures or omissions, though not specifically mentioned above, it being the purpose and intent of this Guaranty and the parties hereto that the obligations of each Guarantor shall be absolute and unconditional and shall not be discharged, impaired or varied except pursuant to Section 13 hereof and by the payment of the principal of, Make-Whole Amount, if any, and interest on the Notes in accordance with their respective terms whenever the same shall become due and payable as in the Notes provided and all other sums due and payable under the Note Purchase Agreement, at the place specified in and all in the manner and with the effect provided in the Notes and the Note Purchase Agreement, as each may be amended or modified from time to time. Without limiting the foregoing, it is understood that repeated and successive demands may be made and recoveries may be had hereunder as and when, from time to time, the Company shall default under or in respect of the terms of the Notes or the Note Purchase Agreement and that notwithstanding recovery hereunder for or in respect of any given default or defaults by the Company under the Notes or the Note Purchase Agreement, this Guaranty shall remain in full force and effect and shall apply to each and every subsequent default.

(d) All rights of any Holder may be transferred or assigned at any time and shall be considered to be transferred or assigned at any time or from time to time upon the transfer of such Note in accordance with the Note Purchase Agreement whether with or without the consent of or notice to the Guarantors under this Guaranty or to the Company.

(e) To the extent of any payments made under this Guaranty, the Guarantors shall be subrogated to the rights of the Holder or Holders upon whose Notes such payment was made, but each Guarantor covenants and agrees that such right of subrogation shall be junior and subordinate in right of payment to the prior indefeasible final payment in cash in full of all amounts due and owing by the Company with respect to the Notes and the Note Purchase Agreement and by the Guarantors under this Guaranty, and the Guarantors shall not take any action to enforce such right of subrogation, and the Guarantors shall not accept any payment in respect of such right of subrogation, until all amounts due and owing by the Company under or in respect of the Notes and the Note Purchase Agreement and all amounts due and owing by the Guarantors hereunder have indefeasibly been finally paid in cash in full. If any amount shall be paid to any Guarantor in violation of the preceding sentence at any time prior to the indefeasible payment in cash in full (or other satisfaction agreed to by the Holders) of the Notes and all other amounts payable under the Notes, the Note Purchase Agreement and this Guaranty, such amount shall be held in trust for the benefit of the Holders and shall, except to the extent the Holders have received payment, promptly be paid to the Holders to be credited and applied to the amounts due or to become due with respect to the Notes and all other amounts payable under the Note Purchase Agreement and this Guaranty, whether matured or unmatured. Each Guarantor acknowledges that it has received direct and indirect benefits from the financing arrangements contemplated by the Note Purchase Agreement and that the waiver set forth in this paragraph (e) is knowingly made as a result of the receipt of such benefits.

E-2.2(a)-9

(f) To the extent of any payments made under this Guaranty, each Guarantor making such payment shall have a right of contribution from the other Guarantors, but such Guarantor covenants and agrees that such right of contribution shall be subordinate in right of payment to the rights of the Holders for which full payment has not been made or provided for and, to that end, such Guarantor agrees not to claim or enforce any such right of contribution unless and until all of the Notes and all other sums due and payable under the Note Purchase Agreement have been fully and irrevocably paid and discharged.

(g) Each Guarantor agrees that to the extent the Company, any other Guarantor or any other Person makes any payment on any Note, which payment or any part thereof is subsequently invalidated, voided, declared to be fraudulent or preferential, set aside, recovered, rescinded, or otherwise defeased or is required to be retained by or repaid to a trustee, receiver, or any other Person under any bankruptcy code, common law, or equitable cause, then and to the extent of such payment, the obligation or the part thereof intended to be satisfied shall be revived and continued in full force and effect with respect to the Guarantors’ obligations hereunder, as if said payment had not been made. The liability of the Guarantors hereunder shall not be reduced or discharged, in whole or in part, by any payment to any Holder from any source that is thereafter paid, returned or refunded in whole or in part by reason of the assertion of a claim of any kind relating thereto, including, but not limited to, any claim for breach of contract, breach of warranty, preference, illegality, invalidity, or fraud asserted by any account debtor or by any other Person.

(h) No Holder shall be under any obligation: (1) to marshal any assets in favor of the Guarantors or in payment of any or all of the liabilities of the Company under or in respect of the Notes or the obligations of the Guarantors hereunder or (2) to pursue any other remedy that the Guarantors may or may not be able to pursue themselves and that may lighten the Guarantors’ burden, any right to which each Guarantor hereby expressly waives.

(i) The obligations of each Guarantor under this Guaranty rank pari passu in right of payment with all other Debt of such Guarantor which is not secured or which is not expressly subordinated in right of payment to any other unsecured Debt of such Guarantor.

SECTION 5.

REPRESENTATIONS AND WARRANTIES OF THE GUARANTORS.

Each Guarantor represents and warrants to each Holder that:

(a) Such Guarantor is a corporation or other legal entity duly organized, validly existing and in good standing under the laws of its jurisdiction of organization (if applicable), and is duly qualified as a foreign corporation or other legal entity 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 would not, individually or in the aggregate, reasonably be expected to have a material adverse effect on (1) the business, operations, affairs, financial condition, assets or properties of the Company and its subsidiaries, taken as a whole, or (2) the ability of such Guarantor to perform its obligations under this Guaranty, or (3) the validity or enforceability of this Guaranty. Such Guarantor has the 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 Guaranty and to perform the provisions hereof.

E-2.2(a)-10

(b) This Guaranty has been duly authorized by all necessary action on the part of such Guarantor, and upon execution and delivery of this Guaranty and of the Note Purchase Agreement and receipt of consideration for the Note Purchase Agreement and the Notes, this Guaranty will constitute a legal, valid and binding obligation of such Guarantor enforceable against such Guarantor in accordance with its terms, except as such enforceability may be limited by (1) applicable bankruptcy, insolvency, reorganization, moratorium or other similar laws affecting the enforcement of creditors’ rights generally and (2) general principles of equity (regardless of whether such enforceability is considered in a proceeding in equity or at law).

(c) The execution, delivery and performance by such Guarantor of this Guaranty will not (1) 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 such Guarantor under any indenture, mortgage, deed of trust, loan, purchase or credit agreement, lease, charter document or by-law, or any other material agreement or instrument to which such Guarantor is bound or by which such Guarantor or any of its properties may be bound or affected, (2) 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 such Guarantor or (3) violate any provision of any statute or other rule or regulation of any Governmental Authority applicable to such Guarantor.

(d) No consent, approval or authorization of, or registration, filing or declaration with, any Governmental Authority by the Guarantor is required in connection with the execution, delivery or performance by such Guarantor of this Guaranty.

(e) Such Guarantor on a consolidated basis has capital not unreasonably small in relation to its business or any contemplated or undertaken transaction and has assets having a value both at fair valuation and at present fair salable value greater than the amount required to pay its debts as they become due and greater than the amount that will be required to pay its probable liability on its existing debts as they become absolute and matured. Such Guarantor does not intend to incur or believe that it will incur, debts beyond its ability to pay such debts as they become due. Such Guarantor will not be rendered insolvent by the execution and delivery of, and performance of its obligations under, this Guaranty. Such Guarantor does not intend to hinder, delay or defraud its creditors by or through the execution and delivery of, or performance of its obligations under, this Guaranty.

SECTION 6.

GUARANTOR COVENANTS.

From and after the date hereof and continuing so long as any amount on the Notes remains unpaid (i) each Guarantor (other than the Reporting Entity) agrees to comply with the terms and provisions of Sections 9.1, 9.2, 9.3, 9.4 and 9.5 of the Note Purchase Agreement, insofar as such provisions apply to such Guarantor, as if such provisions referred to such Guarantor, and (ii) the Reporting Entity agrees to comply with the terms and provisions of the Note Purchase Agreement, insofar as such provisions apply to the Reporting Entity.

(a) Each payment by a Foreign Guarantor shall be made, under all circumstances, without reduction for, and free from and clear of, and without deduction or withholding for or because of, any and all present or future taxes, levies, imposts, duties or similar governmental assessments and charges (but not including, for the avoidance of doubt, any taxes, levies, imposts, duties or other governmental assessments or charges imposed on or measured by reference to the income, receipts or gains of the relevant Holder, or any branch profits taxes, or any taxes, levies, imposts, duties or other governmental assessments or charges imposed as a result of a present or former connection of the relevant Holder with the jurisdiction imposing such tax, levy, impost, duty or other governmental assessment or charge) imposed, levied, collected, assessed, or required to be deducted or withheld by the government of any country or jurisdiction (or any authority therein or thereof), other than the United States of America or any political subdivision or authority therein or thereof, from which payments hereunder or on or in respect of the Notes are actually made (hereinafter called “Non-U.S. Taxes”), unless such imposition, levy, collection, assessment, deduction or withholding is required by law. If a Foreign Guarantor is required by law to make any payment pursuant to this Guaranty subject to such deduction or withholding, then such Guarantor shall forthwith (a) pay over to the government or taxing authority imposing such tax the full amount required to be so deducted or withheld (including the full amount required to be deducted or withheld from or otherwise paid by such Guarantor in respect of the Tax Indemnity Amounts (as defined below)), and (b) pay each Holder such additional amounts (“Tax Indemnity Amounts”) as may be necessary in order that the net amount of every payment made to each Holder, after provision for payment of such Non-U.S. Taxes (including any required deduction, withholding or other payment of tax on or with respect to such Tax Indemnity Amounts), shall be equal to the amount which such Holder would have received had there been no deduction or withholding. Notwithstanding the provisions of this Section 7(a), no such Tax Indemnity Amounts shall be payable for or on account of any tax, levy, impost, duty, assessment or other governmental charge that is imposed or withheld by reason of the failure of the Holder to complete, execute and deliver to such Guarantor any form or document to the extent applicable to such Holder that would enable such Guarantor to make payments pursuant to this Section 7 in the Guaranty without, or at a reduced rate of, deduction or withholding for taxes, levies, imposts, duties, assessments or governmental charges, which form or document shall be delivered prior to the making of any payment by such Guarantor hereunder, and in any event within twenty days of a written request therefor by such Guarantor (and any such Holder shall promptly provide such updated forms or documents in the event forms or documents previously submitted by such Holder become inaccurate or obsolete). Notwithstanding anything to the contrary herein, Tax Indemnity Amounts shall be payable pursuant to this Section 7 only to the extent that the net amount that would otherwise be received by a Holder with respect to a payment by a Foreign Guarantor pursuant to this Guaranty, after such Foreign Guarantor has deducted or withheld any Non-U.S. Taxes as required by law, is less than the net amount such Holder would have received had such payment been made by the Company on the applicable Notes.

(b) HMRC DT Treaty Passport Scheme

Any Holder who holds a passport under the HMRC DT Treaty Passport Scheme, and which wishes that scheme to apply to this Guaranty, shall include an indication to that effect by

E-2.2(a)-12

providing its HMRC DT Treaty Passport Scheme reference number and its jurisdiction of tax residence as follows: (a) in the case of each Purchaser, providing such information (i) in Schedule A to the Note Purchase Agreement at the date of the Note Purchase Agreement or (ii) in a written notice delivered to the Reporting Entity in accordance with Section 18 of the Note Purchase Agreement prior to the date that a Holder has proceeded against any United Kingdom resident Guarantor under this Guaranty, and (b) in the case of any transferee of a Note, providing such information in writing to the Reporting Entity in accordance with Section 18 of the Note Purchase Agreement at the time of transfer.

Where a Holder has provided its HMRC DT Treaty Passport Scheme reference number and jurisdiction of tax residence as provided above, the Reporting Entity shall use its commercially reasonable efforts to file (if it is an entity resident in the United Kingdom) or cause to be filed in respect of any United Kingdom resident Guarantor a duly completed form DTTP2 or any prescribed replacement form in respect of such Holder with HMRC within 30 business days after a Holder has proceeded against any United Kingdom resident Guarantor under this Guaranty and shall provide such Holder with a copy of that filing if so requested by such Holder.

SECTION 8.

GOVERNING LAW.

(a) THIS GUARANTY SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK APPLICABLE THEREIN.

(b) Each Guarantor hereby (1) irrevocably submits and consents to the jurisdiction of the federal court located within the County of New York, State of New York (or if such court lacks jurisdiction, the State courts located therein), and irrevocably agrees that all actions or proceedings relating to this Guaranty may be litigated in such courts, and (2) waives any objection which it may have based on improper venue or forum non conveniens to the conduct of any proceeding in any such court and waives personal service of any and all process upon it, and (3) consents that all such service of process be made by delivery to it at the address of such Person set forth in Section 11 below or to its agent referred to below at such agent’s address set forth below (with a courtesy copy to such Guarantor at the address set forth in Section 11) and that service so made shall be deemed to be completed upon actual receipt. Each Guarantor hereby irrevocably appoints the Company, as its agent for the purpose of accepting service of any process. In the event the Company (or any successor thereto) shall in accordance with the terms of the Note Purchase Agreement be organized under the laws of any jurisdiction other than any state of the United States or the District of Columbia, each Guarantor agrees it shall irrevocably appoint CT Corporation System, with an office on the date hereof at 111 Eighth Avenue, New York, New York 10011, as its agent for the purpose of accepting service of any process within the State of New York. Nothing contained in this section shall affect the right of any Holder to serve legal process in any other manner permitted by law or to bring any action or proceeding in the courts of any jurisdiction against a Guarantor or to enforce a judgment obtained in the courts of any other jurisdiction.

E-2.2(a)-13

Guaranty, any financing agreement, any loan party document or any other instrument, document or agreement executed or delivered in connection herewith or the transactions related hereto. The parties hereto hereby agree and consent that any such claim, demand, action or cause of action shall be decided by court trial without a jury and that any of them may file an original counterpart or a copy of this Guaranty with any court as written evidence of the consent of the parties hereto to the waiver of their right to trial by jury.

SECTION 9.

CURRENCY OF PAYMENTS, INDEMNIFICATION.

Any payment made by a Guarantor to any Holder for the account of any such Holder in respect of any amount payable by a Guarantor shall be made in the lawful currency of the United States of America (“U.S. Dollars”). Any amount received or recovered by such Holder other than in U.S. Dollars (whether as a result of, or of the enforcement of, a judgment or order of any court, or in the liquidation or dissolution of a Guarantor or otherwise) in respect of any such sum expressed to be due hereunder or under the Notes shall constitute a discharge of a Guarantor only to the extent of the amount of U.S. Dollars which such Holder is able, in accordance with normal banking procedures, to purchase with the amount so received or recovered in that other currency on the date of the receipt or recovery (or, if it is not practicable to make that purchase on such date, on the first date on which it is practicable to do so). If the amount of U.S. Dollars so purchased is less than the amount of U.S. Dollars expressed to be due hereunder or under the Notes, such Guarantor agrees as a separate and independent obligation from the other obligations herein, notwithstanding any such judgment, to indemnify the Holder against the loss. If the amount of U.S. Dollars so purchased exceeds the amount of U.S. Dollars expressed to be due hereunder or under the Notes, then such Holder agrees to promptly remit such excess to such Guarantor.

SECTION 10.

AMENDMENTS, WAIVERS AND CONSENTS.

(a) This Guaranty may be amended, and the observance of any term hereof may be waived (either retroactively or prospectively), with (and only with) the written consent of each Guarantor and the Required Holders; provided, that without the written consent of all of the Holders, no such waiver, modification, alteration or amendment shall be effective which will reduce the scope of the guaranty set forth in this Guaranty, amend any of the terms or provisions of Section 2 or 6 hereof or amend this Section 10. No such amendment or modification shall extend to or affect any obligation not expressly amended or modified or impair any right consequent thereon.

(b) The Guarantors will provide each Holder (irrespective of the amount of Notes then owned by it) with sufficient information, sufficiently far in advance of the date a decision is required, to enable such Holder to make an informed and considered decision with respect to any proposed amendment, waiver or consent in respect of any of the provisions hereof. The Guarantors will deliver executed or true and correct copies of each amendment, waiver or consent effected pursuant to the provisions of this Section 10 to each Holder promptly following the date on which it is executed and delivered by, or receives the consent or approval of, the requisite Holders.

E-2.2(a)-14

(c) The Company will not directly or indirectly pay or cause to be paid any remuneration, whether by way of fee or otherwise, or grant any security, to any Holder as consideration for or as an inducement to the entering into by any Holder of any waiver or amendment of any of the terms and provisions hereof unless such remuneration is concurrently paid, or security is concurrently granted, on the same terms, ratably to each Holder even if such Holder did not consent to such waiver or amendment.

(d) Any amendment or waiver consented to as provided in this Section 10 applies equally to all Holders and is binding upon them and upon each future Holder and upon the Guarantors. No such amendment or waiver will extend to or affect any obligation, covenant or agreement not expressly amended or waived or impair any right consequent thereon. No course of dealing between the Guarantors and any Holder nor any delay in exercising any rights hereunder shall operate as a waiver of any rights of any Holder. As used herein, the term “this Guaranty” and references thereto shall mean this Guaranty as it may from time to time be amended or supplemented.

(e) Solely for the purpose of determining whether the Holders of the requisite percentage of the aggregate principal amount of Notes then outstanding approved or consented to any amendment, waiver or consent to be given under this Guaranty, Notes directly or indirectly owned by any Guarantor, the Company or any of their respective subsidiaries or Affiliates shall be deemed not to be outstanding.

SECTION 11.

NOTICES.

All notices and communications provided for hereunder shall be in writing and sent (a) electronically (including by telefacsimile if the sender on the same day sends a confirming copy of such notice by a recognized overnight delivery service (charges prepaid) or e-mail) or (b) by registered or certified mail with return receipt requested (postage prepaid), or (c) by a recognized overnight delivery service (with charges prepaid). Any such notice must be sent:

(1) if to a Holder listed on Schedule A of the Note Purchase Agreement or such Holder’s nominee, to such Holder or such Holder’s nominee at the address specified for such communications on Schedule A, or at such other address as such Holder or such Holder’s nominee shall have specified to any Guarantor or the Company in writing,

(2) if to any other Holder, to such Holder at such address as such Holder shall have specified to any Guarantor or the Company in writing, or

(3) if to any Guarantor, to such Guarantor c/o the Company at its address set forth at the beginning of the Note Purchase Agreement to the attention of Corporate Treasurer, or at such other address as such Guarantor shall have specified to the Holders in writing.

Notices under this Section 11 will be deemed given only when actually received. Notices and other communications sent electronically shall be deemed received on the day such notices or other communications are sent unless such notice or other communication is not sent during the normal business hours of the recipient, in which case such notice or communication shall be deemed to have been sent at the opening of business on the next business day.

E-2.2(a)-15

SECTION 12.

MISCELLANEOUS.

(a) No remedy herein conferred upon or reserved to any Holder is intended to be exclusive of any other available remedy or remedies, but each and every such remedy shall be cumulative and shall be in addition to every other remedy given under this Guaranty now or hereafter existing at law or in equity. No delay or omission to exercise any right or power accruing upon any default, omission or failure of performance hereunder shall impair any such right or power or shall be construed to be a waiver thereof but any such right or power may be exercised from time to time and as often as may be deemed expedient. In order to entitle any Holder to exercise any remedy reserved to it under the Guaranty, it shall not be necessary for such Holder to physically produce its Note in any proceedings instituted by it or to give any notice, other than such notice as may be herein expressly required.

(b) The Guarantors will pay all sums becoming due under this Guaranty by the method and at the address specified in the Note Purchase Agreement, or by such other method or at such other address as any Holder shall have from time to time specified to the Guarantors in writing for such purpose, without the presentation or surrender of this Guaranty or any Note.

(c) Any provision of this Guaranty that is prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof, and any such prohibition or unenforceability in any jurisdiction shall (to the full extent permitted by law) not invalidate or render unenforceable such provision in any other jurisdiction.

(d) If the whole or any part of this Guaranty shall be now or hereafter become unenforceable against any one or more of the Guarantors for any reason whatsoever or if it is not executed by any one or more of the Guarantors, this Guaranty shall nevertheless be and remain fully binding upon and enforceable against each other Guarantor as if it had been made and delivered only by such other Guarantors.

(e) This Guaranty shall be binding upon each Guarantor and its successors and assigns and shall inure to the benefit of each Holder and its successors and assigns so long as its Notes remain outstanding and unpaid.

(f) This Guaranty may be executed in any number of counterparts, each of which shall be an original but all of which together shall constitute one instrument. Each counterpart may consist of a number of copies hereof, each signed by less than all, but together signed by all, of the parties hereto.

SECTION 13.

RELEASE.

Notwithstanding anything that may be contained herein to the contrary, the Holders agree that, in accordance with, and pursuant to the requirements of, Section 2.2(e) of the Note Purchase

E-2.2(a)-16

Agreement, this Guaranty (other than, if New Steris Limited is the Reporting Entity, with respect to New Steris Limited) shall be automatically released and discharged without the necessity of further action on the part of the Holders if, and to the extent, the corresponding guaranty given pursuant to the terms of each Material Credit Facility is released and discharged; provided that in the event the Guarantor shall again become obligated under or with respect to the previously discharged Guaranty pursuant to the terms and provisions of the Note Purchase Agreement, then the obligations of such Guarantor under this Guaranty shall be reinstated and any release thereof previously given shall be deemed null and void, and such Guaranty shall again benefit the Holders on an equal and pro rata basis. Any release by the Holders shall be deemed to have occurred concurrently with the release and discharge under the Material Credit Facilities. The Company shall promptly notify the Holders of any release of a Affiliate Guaranty pursuant to this Section 13 and shall deliver evidence of any release or discharge of a guaranty or Lien in customary form.

(7) any order, judgment, decree, ruling or regulation (whether or not valid) of any court of any nation or of any political subdivision thereof or any body, agency, department, official or administrative or regulatory agency of any thereof or any other action, happening, event or reason whatsoever which shall delay, interfere with, hinder or prevent, or in any way adversely affect, the performance by the Company, any Guarantor or any other Person of its respective obligations under or in respect of the Notes, the Note Purchase Agreement, this Guaranty or any other agreement; or

(8) the failure of any Guarantor to receive any benefit from or as a result of its execution, delivery and performance of this Guaranty; or

Guarantor or any other Person to keep and perform any obligation, covenant or agreement under the terms of the Notes, the Note Purchase Agreement, this Guaranty or any other agreement or failure to resort for payment to the Company, any other Guarantor or to any other Person or to any other guaranty or to any property, security, Liens or other rights or remedies; or

effect provided in the Notes and the Note Purchase Agreement, as each may be amended or modified from time to time. Without limiting the foregoing, it is understood that repeated and successive demands may be made and recoveries may be had hereunder as and when, from time to time, the Company shall default under or in respect of the terms of the Notes or the Note Purchase Agreement and that notwithstanding recovery hereunder for or in respect of any given default or defaults by the Company under the Notes or the Note Purchase Agreement, this Guaranty shall remain in full force and effect and shall apply to each and every subsequent default.

(e) To the extent of any payments made under this Guaranty, the Guarantors shall be subrogated to the rights of the Holder or Holders upon whose Notes such payment was made, but each Guarantor covenants and agrees that such right of subrogation shall be junior and subordinate in right of payment to the prior indefeasible final payment in cash in full of all amounts due and owing by the Company with respect to the Notes and the Note Purchase Agreement and by the Guarantors under this Guaranty, and the Guarantors shall not take any action to enforce such right of subrogation, and the Guarantors shall not accept any payment in respect of such right of subrogation, until all amounts due and owing by the Company under or in respect of the Notes and the Note Purchase Agreement and all amounts due and owing by the Guarantors hereunder have indefeasibly been finally paid in cash in full. If any amount shall be paid to any Guarantor in violation of the preceding sentence at any time prior to the indefeasible payment in cash in full (or other satisfaction agreed to by the Holders) of the Notes and all other amounts payable under the Notes, the Note Purchase Agreement and this Guaranty, such amount shall be held in trust for the benefit of the Holders and shall, except to the extent the Holders have received payment, promptly be paid to the Holders to be credited and applied to the amounts due or to become due with respect to the Notes and all other amounts payable under the Note Purchase Agreement and this Guaranty, whether matured or unmatured. Each Guarantor acknowledges that it has received direct and indirect benefits from the financing arrangements contemplated by the Note Purchase Agreement and that the waiver set forth in this paragraph (e) is knowingly made as a result of the receipt of such benefits.

rescinded, or otherwise defeased or is required to be retained by or repaid to a trustee, receiver, or any other Person under any bankruptcy code, common law, or equitable cause, then and to the extent of such payment, the obligation or the part thereof intended to be satisfied shall be revived and continued in full force and effect with respect to the Guarantors’ obligations hereunder, as if said payment had not been made. The liability of the Guarantors hereunder shall not be reduced or discharged, in whole or in part, by any payment to any Holder from any source that is thereafter paid, returned or refunded in whole or in part by reason of the assertion of a claim of any kind relating thereto, including, but not limited to, any claim for breach of contract, breach of warranty, preference, illegality, invalidity, or fraud asserted by any account debtor or by any other Person.

SECTION 5.

REPRESENTATIONS AND WARRANTIES OF THE GUARANTORS.

Each Guarantor represents and warrants to each Holder that:

SECTION 7.

PAYMENTS FREE AND CLEAR OF TAXES.

collected, assessed, or required to be deducted or withheld by the government of any country or jurisdiction (or any authority therein or thereof), other than the United States of America or any political subdivision or authority therein or thereof, from which payments hereunder or on or in respect of the Notes are actually made (hereinafter called “Non-U.S. Taxes”), unless such imposition, levy, collection, assessment, deduction or withholding is required by law. If a Foreign Guarantor is required by law to make any payment pursuant to this Guaranty subject to such deduction or withholding, then such Guarantor shall forthwith (a) pay over to the government or taxing authority imposing such tax the full amount required to be so deducted or withheld (including the full amount required to be deducted or withheld from or otherwise paid by such Guarantor in respect of the Tax Indemnity Amounts (as defined below)), and (b) pay each Holder such additional amounts (“Tax Indemnity Amounts”) as may be necessary in order that the net amount of every payment made to each Holder, after provision for payment of such Non-U.S. Taxes (including any required deduction, withholding or other payment of tax on or with respect to such Tax Indemnity Amounts), shall be equal to the amount which such Holder would have received had there been no deduction or withholding. Notwithstanding the provisions of this Section 7(a), no such Tax Indemnity Amounts shall be payable for or on account of any tax, levy, impost, duty, assessment or other governmental charge that is imposed or withheld by reason of the failure of the Holder to complete, execute and deliver to such Guarantor any form or document to the extent applicable to such Holder that would enable such Guarantor to make payments pursuant to this Section 7 in the Guaranty without, or at a reduced rate of, deduction or withholding for taxes, levies, imposts, duties, assessments or governmental charges, which form or document shall be delivered prior to the making of any payment by such Guarantor hereunder, and in any event within twenty days of a written request therefor by such Guarantor (and any such Holder shall promptly provide such updated forms or documents in the event forms or documents previously submitted by such Holder become inaccurate or obsolete). Notwithstanding anything to the contrary herein, Tax Indemnity Amounts shall be payable pursuant to this Section 7 only to the extent that the net amount that would otherwise be received by a Holder with respect to a payment by a Foreign Guarantor pursuant to this Guaranty, after such Foreign Guarantor has deducted or withheld any Non-U.S. Taxes as required by law, is less than the net amount such Holder would have received had such payment been made by the Company on the applicable Notes.

(b) HMRC DT Treaty Passport Scheme

Any Holder who holds a passport under the HMRC DT Treaty Passport Scheme, and which wishes that scheme to apply to this Guaranty, shall include an indication to that effect by providing its HMRC DT Treaty Passport Scheme reference number and its jurisdiction of tax residence as follows: (a) in the case of each Purchaser, providing such information (i) in Schedule A to the Note Purchase Agreement at the date of the Note Purchase Agreement or (ii) in a written notice delivered to the Reporting Entity in accordance with Section 18 of the Note Purchase Agreement prior to the date that a Holder has proceeded against any United Kingdom resident Guarantor under this Guaranty, and (b) in the case of any transferee of a Note, providing such information in writing to the Reporting Entity in accordance with Section 18 of the Note Purchase Agreement at the time of transfer.

SECTION 8.

GOVERNING LAW.

(a) THIS GUARANTY SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK APPLICABLE THEREIN.

(c) The parties hereto waive any right to have a jury participate in resolving any dispute, whether sounding in contract, tort, or otherwise, between them arising out of, connected with, related to or incidental to the relationship established between them in connection with this Guaranty, any financing agreement, any loan party document or any other instrument, document or agreement executed or delivered in connection herewith or the transactions related hereto. The parties hereto hereby agree and consent that any such claim, demand, action or cause of action shall be decided by court trial without a jury and that any of them may file an original counterpart or a copy of this Guaranty with any court as written evidence of the consent of the parties hereto to the waiver of their right to trial by jury.

SECTION 11.

NOTICES.

All notices and communications provided for hereunder shall be in writing and sent (a) electronically (including by telefacsimile if the sender on the same day sends a confirming copy of such notice by a recognized overnight delivery service (charges prepaid) or e-mail) or (b) by registered or certified mail with return receipt requested (postage prepaid), or (c) by a recognized overnight delivery service (with charges prepaid). Any such notice must be sent:

(2) if to any other Holder, to such Holder at such address as such Holder shall have specified to any Guarantor or the Company in writing, or

SECTION 12.

MISCELLANEOUS.

(a) No remedy herein conferred upon or reserved to any Holder is intended to be exclusive of any other available remedy or remedies, but each and every such remedy shall be

cumulative and shall be in addition to every other remedy given under this Guaranty now or hereafter existing at law or in equity. No delay or omission to exercise any right or power accruing upon any default, omission or failure of performance hereunder shall impair any such right or power or shall be construed to be a waiver thereof but any such right or power may be exercised from time to time and as often as may be deemed expedient. In order to entitle any Holder to exercise any remedy reserved to it under the Guaranty, it shall not be necessary for such Holder to physically produce its Note in any proceedings instituted by it or to give any notice, other than such notice as may be herein expressly required.

SECTION 13.

RELEASE.

Notwithstanding anything that may be contained herein to the contrary, the Holders agree that, in accordance with, and pursuant to the requirements of, Section 2.2(e) of the Note Purchase Agreement, this Guaranty (other than, if New Steris Limited is the Reporting Entity, with respect to New Steris Limited) shall be automatically released and discharged without the necessity of further action on the part of the Holders if, and to the extent, the corresponding guaranty given pursuant to the terms of each Material Credit Facility is released and discharged; provided that in the event the Guarantor shall again become obligated under or with respect to the previously discharged Guaranty pursuant to the terms and provisions of the Note Purchase Agreement, then the obligations of such Guarantor under this Guaranty shall be reinstated and any release thereof

previously given shall be deemed null and void, and such Guaranty shall again benefit the Holders on an equal and pro rata basis. Any release by the Holders shall be deemed to have occurred concurrently with the release and discharge under the Material Credit Facilities. The Company shall promptly notify the Holders of any release of a Affiliate Guaranty pursuant to this Section 13 and shall deliver evidence of any release or discharge of a guaranty or Lien in customary form.
