The Series A Notes shall be substantially in the form set out in Exhibit 1-A, Exhibit 1-B and Exhibit 1-C, respectively, with such changes therefrom, if any, as may be approved by the Purchasers and the Company. Certain capitalized

permitted by law, on any overdue installment of interest at the stated rate plus 2%, (f) shall be subject to required amortization, if any, and optional prepayments, and (g) shall be expressed to mature on the stated maturity date, all as
set forth in the Supplemental Note Purchase Agreement relating thereto and shall otherwise be substantially in the form attached hereto as Exhibit 1.2; provided, no Supplemental Notes shall be issued if at the time of issuance
thereof and after giving effect to the application of proceeds therefor, any Default or Event of Default shall have occurred and be continuing. The Series A Notes, and the Supplemental Notes are herein sometimes collectively referred to as the
“Notes” and individually as a “Note.” As used herein, the term “Notes” shall include, without limitation, each Note delivered pursuant to this Agreement and any other Supplemental Note Purchase Agreement
at the Closing and/or at any Supplemental Closing and each Note delivered in substitution or exchange for any such Note pursuant hereto. 
  

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

Section 2.1. Initial Sale of Notes. Subject to the terms and conditions of this Agreement, the Company will issue and sell to each
Purchaser and each Purchaser will purchase from the Company, at the Initial Closing provided for in Section 3, Series A Notes in the principal amount and of the tranche specified opposite such Purchaser’s name in
Schedule A at the purchase price of 100% of the principal amount thereof. The Purchasers named in Schedule A hereto are herein sometimes collectively referred to as the “Initial Purchasers.” The
Purchasers’ obligations hereunder are several and not joint obligations and no Purchaser shall have any liability to any Person for the performance or non-performance of any obligation by any other
Purchaser hereunder. Without limiting the foregoing, the Company understands and agrees that each Purchaser’s commitment to purchase the Series A Notes as herein contemplated does not constitute a commitment, obligation or indication of
interest to purchase any Supplemental Notes. 
 Section 2.2. Guarantees. (a) The payment by the Company of all amounts due
with respect to the Notes and the performance by the Company of its obligations under this Agreement will be absolutely and unconditionally guaranteed by the Reporting Entity (if the Reporting Entity is New STERIS Limited) and the Affiliates of the

“Guarantors”) pursuant to the guaranty agreement substantially in the form of Exhibit 2.2(a) attached hereto and made a part hereof (as the same may be amended, modified, extended or renewed, the
“Affiliate Guaranty”). 
 (b) Any instruments, documents and agreements pursuant to which the Reporting
Entity or any Subsidiary agrees to grant Liens in favor of a collateral agent (the “Collateral Agent”) for the benefit of the holders of Notes are hereinafter referred to as the “Collateral
Documents.” The Collateral Documents and the Affiliate Guaranties are hereinafter collectively referred to as the “Security Documents.”

or result therefrom), provided that in the event the Reporting Entity or any Affiliate shall again become obligated under or with respect to the previously discharged Affiliate Guaranty, or again grant the discharged Lien, as the case may be,

	SECTION 8.	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. 
 Section 8.2. Optional Prepayments with
Make-Whole Amount. (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. In the case of each prepayment of Notes of any Series pursuant to this Section 8, the
principal amount of each Note to be prepaid shall mature and become due and payable on the date fixed for such prepayment, together with interest on such principal amount accrued to such date and the applicable
Make-Whole Amount, if any. 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 

  
 -22- 

			
	STERIS CORPORATION		NOTE PURCHASE AGREEMENT

  

 
by such Control Event) shall have been given pursuant to subparagraph (b) of this Section 8.7. If a Change in Control has occurred, such notice shall contain and constitute an
offer to prepay Notes as described in subparagraph (c) of this Section 8.7 and shall be accompanied by the certificate described in subparagraph (g) of this Section 8.7. 

(b) Condition to Company Action. The Company will not take any action that consummates a Change in Control unless (i) at least 15
Business Days prior to such action it shall have given to each holder of Notes written notice containing and constituting an offer to prepay Notes as described in subparagraph (c) of this Section 8.7, accompanied by the certificate
described in subparagraph (g) of this Section 8.7, and (ii) subject to subparagraph (d), contemporaneously with the consummation of such Change in Control, it prepays all Notes required to be prepaid in accordance with
this Section 8.7. 
 (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”). If such Proposed Prepayment Date is in connection
with an offer contemplated by subparagraph (a) of this Section 8.7, such date shall be (subject to subparagraph (f)) not less than 30 days and not more than 120 days after the date of such offer (if the Proposed Prepayment
Date shall not be specified in such offer, the Proposed Prepayment Date shall be the first Business Day after the 45th day after the date of such offer). 

(d) Acceptance/Rejection. A holder of Notes may accept the offer to prepay made pursuant to this Section 8.7 by causing a
notice of such acceptance to be delivered to the Company on or before the date specified in the certificate described in paragraph (g) of this Section 8.7. A failure by a holder of Notes to respond to an offer to prepay made
pursuant to this Section 8.7, or to accept an offer as to all the Notes held by the holder, within such time period shall be deemed to constitute rejection of such offer by such holder. 

(e) Prepayment. Prepayment of the Notes to be prepaid pursuant to this Section 8.7 shall be at 100% of the principal
amount of such Notes, together with interest on such Notes accrued to the date of prepayment, but without Make-Whole Amount or other premium. The prepayment shall be made on the Proposed Prepayment Date except
as provided in subparagraph (f) of this Section 8.7. 
 (f) Deferral Pending Change in Control. The obligation of
the Company to prepay Notes pursuant to the offers required by subparagraphs (a) and (b) and accepted in accordance with subparagraph (d) of this Section 8.7 is subject to the occurrence of the Change in Control in respect
of which such offers and acceptances shall have been made. In the event that such Change in Control has not occurred on the Proposed Prepayment Date in respect thereof, the prepayment shall be deferred until, and shall be made on, the date on which
such Change in Control occurs. Subject to compliance with applicable law and other Company obligations, the Company shall keep each holder of Notes reasonably and timely informed of (i) any such deferral of the date of prepayment, (ii) the
date on which such Change in Control and the 

  
 -23-

prepayment are expected to occur, and (iii) any determination by the Company that efforts to effect such Change in Control have ceased or been abandoned (in which case the offers and

permits, franchises and other governmental authorizations necessary to the ownership of their respective properties or to the conduct of their respective businesses, in each case to the extent necessary to ensure that
non-compliance with such laws, ordinances or governmental rules or regulations or failures to obtain or maintain in effect such licenses, certificates, permits, franchises and other governmental authorizations
would not reasonably be expected, individually or in the aggregate, to have a Material Adverse Effect. 
 Section 9.2.
Insurance. The Reporting Entity will, and will cause each of its Restricted Subsidiaries to, maintain, with financially sound and reputable insurers, insurance with respect to their respective properties and businesses against such casualties

 Section 9.3. Maintenance of Properties. The Reporting Entity will, and will cause
each of its Restricted Subsidiaries to, maintain and keep, or cause to be maintained and kept, their respective properties in good repair, working order and condition (other than ordinary wear and tear or any casualty which would not, individually
or in the aggregate, have a Material Adverse Effect), so that the business carried on in connection therewith may be properly conducted at all times; provided that this Section 9.3 shall not prevent the Reporting Entity or any
Restricted Subsidiary from discontinuing the operation and the maintenance of any of its properties if such discontinuance is desirable in the conduct of its business and the Reporting Entity has concluded that such discontinuance would not,
individually or in the aggregate, have a Material Adverse Effect. 
 Section 9.4. Payment of Taxes. The Reporting Entity will,
and will cause each of its Restricted Subsidiaries to, file all income tax or similar tax returns required to be filed in any jurisdiction and to pay and discharge all taxes shown to be due and payable on such returns and all other taxes,
assessments, governmental charges, or levies payable by any of them, to the extent such taxes and assessments have become due and payable and before they have become delinquent; provided that neither the Reporting Entity nor any Restricted
Subsidiary need pay any such tax or assessment if (a) the amount, applicability or validity thereof is contested by the Reporting Entity or such Restricted Subsidiary on a timely basis in good faith and in appropriate proceedings, and the
Reporting Entity or a Restricted Subsidiary has established adequate reserves therefor in accordance with GAAP (or English GAAP, as applicable) on the books of the Reporting Entity or such Subsidiary or (b) the nonpayment of all such taxes and
assessments in the aggregate would not reasonably be expected to have a Material Adverse Effect.

Existence, Etc. Except as permitted by Section 10.4, the Reporting Entity will at all times preserve and keep in full force and effect its legal existence. Except as permitted by Sections 10.4 and 10.5, the
Reporting Entity will at all times preserve and keep in full force and effect the legal existence of each of its Restricted Subsidiaries (unless merged into the Restricted Entity or a Restricted Subsidiary) and all rights and franchises of the
Reporting Entity and its Restricted Subsidiaries unless, in the good faith judgment of the Reporting Entity, the termination of or failure to preserve and keep in full force and effect such corporate existence, right or franchise would not,
individually or in the aggregate, have a Material Adverse Effect. 
 Section 9.6. Notes to Rank Pari Passu. The Notes and all
other obligations under this Agreement of the Company are and at all times shall rank at least pari passu in right of payment with all other present and future unsecured Debt (actual or contingent) of the Company which is not expressed to be

 Section 9.7. Guaranty. The Reporting Entity will cause each Affiliate (other than
the Company) which delivers a Guaranty of outstanding borrowings or available borrowing capacity (subject only to customary conditions) under a Material Credit Facility or becomes an obligor, co-obligor,
borrower or co-borrower of outstanding borrowings or has available borrowing capacity (subject only to customary conditions) under a Material Credit Facility to concurrently enter into an Affiliate Guaranty,
and as promptly as reasonably practicable will deliver to each of the holders of the Notes the following items:

establish the existence and, if applicable, good standing of such Affiliate and the authorization of the transactions contemplated by the Affiliate Guaranty; 

(d) an opinion of counsel reasonably satisfactory to the Required Holders to the effect that such Affiliate Guaranty has been
duly authorized, executed and delivered and constitutes the legal, valid and binding contract and agreement of such Affiliate enforceable in accordance with its terms, subject to customary exceptions, assumptions and qualifications; provided
that an opinion from a nationally recognized law firm and/or in-house counsel of the Company shall be reasonably satisfactory to the Required Holders; and 

(e) with respect to any Foreign Guarantor, evidence of the acceptance by the Company or CT Corporation System, as applicable,

May 14, 2031. 
 For the avoidance of doubt, New STERIS Limited is not a guarantor of outstanding borrowings or available borrowing
capacity (subject only to customary conditions) and is not an obligor, co-obligor, borrower or co-borrower of outstanding borrowings or that has available borrowing
capacity (subject only to customary conditions), in each case under the Bank Credit Agreement and the Bridge Facility, each as in effect on the date hereof prior to the Synergy Closing Date.

Notes (a) all such certificates, resolutions, legal opinions and other related items in substantially the same forms as those delivered to and accepted by such Creditors and such other documentation reasonably acceptable to the Required Holders
in substance and in form, including, without limitation, an intercreditor agreement and opinions of counsel from counsel that is reasonably accepted to the Required Holders (provided that, an opinion from a nationally recognized law firm
and/or in-house counsel of the Company shall be reasonably satisfactory to the Required Holders) and (b) all such amendments to this Agreement and the Collateral Documents as may reasonably be deemed
necessary by the holders of the Notes in order to reflect the existence of such Lien on the assets of the Reporting Entity or such Subsidiary, as applicable, and the Company’s compliance with the requirements of Section 9.6 with
respect to any such security granted to or for the benefit of the holders of the Notes and to or for the benefit of such Creditors. This Section 9.8 shall not apply to any pledge, grant, assignment, conveyance or Lien contemplated to be
granted to any of the agents, lenders or their affiliates in connection with any cash collateral in connection with letters of credit contemplated under the Bank Credit Agreement or any substantially similar pledge, grant, assignment, conveyance or
Lien contemplated by any other Material Credit Facility. 
 Section 9.9. Restricted Subsidiaries. (a) Subject to
paragraphs (b) and (c) below the Reporting Entity will at all times, (i) maintain the aggregate value of the assets of the Reporting Entity and the then existing Restricted Subsidiaries, at not less than 92.5% of Consolidated Total
Assets and (ii) ensure that not less than 92.5% of Consolidated EBITDA for each period is attributable to the Reporting Entity and the then existing Restricted Subsidiaries.

Subsidiaries does not account for 92.5% or more of Consolidated Total Assets or (ii) less than 92.5% of Consolidated EBITDA for a period is attributable to the Reporting Entity and the then existing Restricted Subsidiaries, the Company shall
promptly designate, pursuant to Section 10.7, such other Subsidiaries of the Reporting Entity (which would not otherwise be Restricted Subsidiaries) to be Restricted Subsidiaries hereunder so that such 92.5% thresholds are satisfied.

 (c) Without limiting the foregoing, in the event the Company is not the Reporting Entity, the Company shall, and shall cause each
Guarantor to, be and remain (until such time as such entity is no longer a Guarantor) a Restricted Subsidiary.

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

accounting, appraisal or investment banking firm that is in the good faith determination of the Reporting Entity qualified to render such letter, which letter states that such transaction is on terms that are no less favorable to the Reporting
Entity or the relevant member of the Consolidated Group, as applicable, than would be obtained in a comparable arm’s length transaction with a Person that is not an Affiliate.

default which arises with respect to Synergy Health plc and its Subsidiaries will be deemed not to be a breach of covenant or an Event of Default, as the case may be, if: 

(i) it is capable of remedy and reasonable steps are being taken to remedy it; 

(ii) the circumstances giving rise to it have not been procured or authorized by the Company knowingly in breach of this
Agreement; 
 (iii) it is not reasonably likely to have a material adverse effect on the Reporting Entity and its
Subsidiaries, on a consolidated basis; and 
 (iv) it is not a breach of Section 9.7. 

If the relevant circumstances are continuing on or after the Clean-up Date, there shall be a breach of covenant or
Event of Default, as the case may be, notwithstanding the above. 
  

	SECTION 12.	REMEDIES ON DEFAULT, ETC. 

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. 

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

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

	STERIS CORPORATION		NOTE PURCHASE AGREEMENT

  

 Upon any Note becoming due and payable under this Section 12.1, whether
automatically or by declaration, such Note will forthwith mature and the entire unpaid principal amount of such Note, plus (i) all accrued and unpaid interest thereon and (ii) the Make-Whole Amount
determined in respect of such principal amount (to the full extent permitted by applicable law), shall all be immediately due and payable, in each and every case without presentment, demand, protest or further notice, all of which are hereby waived.
The 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. 
 Section 12.3.
Rescission. At any time after any Series of Notes have been declared due and payable pursuant to clause (b) or (c) of Section 12.1, the holders of not less than 51% in principal amount of each such Series of the Notes, by
written notice to the Company, may rescind and annul any such declaration and its consequences if (a) the Company has paid all overdue interest on the Notes, all principal of and Make-Whole Amount, if
any, on any Notes that are due and payable and are unpaid other than by reason of such declaration, and all interest on such overdue principal and Make-Whole Amount, if any, and (to the extent permitted by
applicable law) any overdue interest in respect of the Notes, at the Default Rate, (b) all Events of Default and Defaults, other than non-payment of amounts that have become due solely by reason of such
declaration, have been cured or have been waived pursuant to Section 17, and (c) no judgment or decree has been entered for the payment of any monies due pursuant hereto or to the Notes. No rescission and annulment under this
Section 12.3 will extend to or affect any subsequent Event of Default or Default or impair any right consequent thereon. 

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. Without

limiting the obligations of the Company under Section 15, the Company will pay to the holder of each Note on demand such further amount as shall be sufficient to cover all costs and

of such Note or its attorney duly authorized in writing and accompanied by the address for notices of each transferee of such Note or part thereof), the Company shall execute and deliver, at the Company’s expense (except as provided below), one
or more new Notes (as requested by the holder thereof) of the same Series (and of the same tranche if such Series has separate tranches) in exchange therefor, in an aggregate principal amount equal to the unpaid principal amount of the surrendered
Note. Each such new Note shall be payable to such Person as such holder may request and shall be substantially in the form of Exhibit 1-A,
Exhibit 1-B, Exhibit 1-C or Exhibit 1.5, as the case may be. Each such new Note shall be dated and bear interest from the date to

mutilation), and 
 (a) in the case of loss, theft or destruction, of indemnity reasonably satisfactory to it
(provided that if the holder of such Note is, or is a nominee for, an original Purchaser or another holder of a Note with a minimum net worth of at least $50,000,000, such Person’s own unsecured agreement of indemnity shall be deemed to
be satisfactory), or

 the Company at its own expense shall execute and deliver, in lieu thereof, a new Note of the same Series (and

mutilated Note if no interest shall have been paid thereon.

may be, or by such other method or at such other address as such Purchaser shall have from time to time specified to the Company in writing for such purpose, without the presentation or surrender of such Note or the making of any notation thereon,
except that upon written request of the Company made concurrently with or reasonably promptly after payment or prepayment in full of any Note, such Purchaser shall surrender such Note for cancellation, reasonably promptly after any such request, to
the Company at its principal executive office or at the place of payment most recently designated by the Company pursuant to Section 14.1. Prior to any sale or other disposition of any Note held by a Purchaser or its nominee it will, at
its election, either endorse thereon the amount of principal paid thereon and the last date to which interest has been paid thereon or surrender such Note to the Company in exchange for a new Note or Notes of the same Series and tranche pursuant to
Section 13.2. The Company will afford the benefits of this Section 14.2 to any Institutional Investor that is the direct or indirect transferee of any Note purchased by a Purchaser under this Agreement and that has made the

Agreement and any Supplemental Note Purchase Agreement and the Notes embody the entire agreement and understanding between each Purchaser and the Company and supersede all prior agreements and
understandings relating to the subject matter hereof. 
  

	SECTION 17.	AMENDMENT AND WAIVER. 

 Section 17.1.
Requirements. (a) This Agreement (and/or any Supplemental Note Purchase Agreement) and the Notes may be amended, and the observance of any term hereof or of the Notes may be waived (either retroactively or prospectively), with (and only
with) the written consent of the Company and the Required Holders, except that (a) no amendment or waiver of any of the provisions of Section 1, 2.1, 2.3, 3, 4, 5 (subject to permitted amendments
or supplements pursuant to Supplemental Note Purchase Agreements in respect to Notes issued thereunder), 6 or 21 hereof, or any defined term (as it is used therein), will be effective as to any Purchaser unless consented to by such
Purchaser in writing, and (b) no such amendment or waiver may, without the written consent of the holder of each Note at the time outstanding affected thereby, (i) subject to the provisions of Section 12 relating to
acceleration or rescission, change the amount, time or allocation of any prepayment or payment of principal of, or reduce the rate or change the time of payment or method of computation of interest or of the
Make-Whole Amount on, the Notes, (ii) change the percentage of the principal amount of the Notes the holders of which are required to consent to any such amendment or waiver, or (iii) amend any of
Section 8, 11(a), 11(b), 12, 17 or 20. As used herein and in the Notes, the term “this Agreement” and references thereto shall mean this Agreement as it may from time to time be amended or
supplemented and, without limiting the generality of the foregoing, shall include all Supplemental Note Purchase Agreements. 
 (b) Any
Collateral Document may be amended in the manner prescribed in such document, and the Affiliate Guaranties may be amended in the manner prescribed in such documents, and all amendments to any Security Document obtained in conformity with such
requirements shall bind all holders of the Notes. 
 Section 17.2. Solicitation of Holders of Notes. 

(a) Solicitation. The Company will provide each holder of the Notes (irrespective of the amount, Series or tranche 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 or of the Notes or of any of the Security Documents. The Company will deliver executed or true and correct copies of each amendment, waiver or consent effected pursuant to the provisions of this Section 17 or of any of
the Security Documents to each holder of outstanding Notes promptly following the date on which it is executed and delivered by, or receives the consent or approval of, the requisite holders of Notes. 

(b) Payment. Neither the Reporting Entity nor the Company will directly or indirectly pay or cause to be paid any remuneration,
whether by way of supplemental or additional interest, fee or otherwise or issue any Guaranty, or grant any security, to any holder of any Series or tranche of Notes as consideration for or as an inducement to the entering into by any holder of

  
 -45- 

			
	STERIS CORPORATION		NOTE PURCHASE AGREEMENT

  

 
Notes of any waiver or amendment of any of the terms and provisions hereof or of any Note or any Security Document unless such remuneration is concurrently paid, or Guaranty or security is
concurrently granted, on the same terms, ratably to each of the holders of each Series and tranche of the Notes then outstanding even if such holder did not consent to such waiver or amendment. 

(c) Consent in Contemplation of Transfer. Any consent made pursuant to this Section 17 by the holder of any Note that has
transferred or has agreed to transfer such Note to the Company, any Subsidiary or any Affiliate of the Company and has provided or has agreed to provide such written consent as a condition to such transfer shall be void and of no force or effect
except solely as to such holder, and any amendments effected or waivers granted or to be effected or granted that would not have been or would not be so effected or granted but for such consent (and the consents of all other holders of Notes that
were acquired under the same or similar conditions) shall be void and of no force or effect except solely as to such transferring holder. 

Section 17.3. Binding Effect, Etc. Any amendment or waiver consented to as provided in this Section 17 applies equally
to all holders of each Series and tranche of Notes and is binding upon them and upon each future holder of any Note of any Series and tranche and upon the Company without regard to whether such Note has been marked to indicate such amendment or
waiver. No such amendment or waiver will extend to or affect any obligation, covenant, agreement, Default or Event of Default not expressly amended or waived or impair any right consequent thereon. No course of dealing between the Company and the
holder of any Note of any Series or tranche of Notes nor any delay in exercising any rights hereunder or under any Note shall operate as a waiver of any rights of any holder of each Series and tranche of such Note. 

Section 17.4. Notes Held by Company, Etc. 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 Agreement, the Notes or any Security Document, or have directed the taking of any action provided herein or in
the Notes or any Security Document to be taken upon the direction of the holders of a specified percentage of the aggregate principal amount of Notes then outstanding, Notes directly or indirectly owned by the Company or any of its Affiliates shall
be deemed not to be outstanding.

such other holder shall have specified to the Company in writing, or 
 (iii) if to the Company or the Reporting Entity, to

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.

	No. [            ]		[Date]
	$[        ]		PPN 859152 E*7

 FOR VALUE RECEIVED, the undersigned, STERIS
CORPORATION (herein called the “Company”), a corporation organized and existing under the laws of the State of Ohio, hereby promises to pay to
[                    ], or registered assigns, the principal sum of [            ]
DOLLARS on May 14, 2025, with interest (computed on the basis of a 360-day year of twelve 30-day months) (a) on the unpaid balance thereof at,
subject to the second paragraph of this Note, the rate of 3.45% per annum from the date hereof, payable semiannually, on the 14th day of May and November in each year, commencing with the May or November next succeeding the date hereof,
until the principal hereof shall have become due and payable, and (b) to the extent permitted by law on any overdue payment (including any overdue prepayment) of principal, any overdue payment of interest and any overdue payment of any Make-Whole Amount (as defined in the Note Purchase Agreement referred to below), payable semiannually as aforesaid (or, at the option of the registered holder hereof, on demand), at, subject to the second paragraph
of this Note, a rate per annum from time to time equal to the Default Rate. Capitalized terms used in this Note and not otherwise defined shall have the meanings set forth in the hereinafter defined Note Purchase Agreement. 

In the event the ratio of Consolidated Total Debt to Consolidated EBITDA as of the last day of any fiscal quarter of the Reporting Entity is
above 3:00 to 1:00, the applicable rate of interest per annum of this Note set forth in clause (a) and (b) of the first paragraph of this Note shall be increased by 0.75% per annum. Changes to the applicable rate of interest shall be
effective as of the first day of the first calendar month after the date upon which the Reporting Entity has delivered the financial statements required pursuant to Sections 7.1(a) and 7.1(b) of the Note Purchase Agreement and the
officer’s certificate pursuant to Section 7.2(a) of the Note Purchase Agreement evidencing that the ratio of Consolidated Total Debt to Consolidated EBITDA as of the last day of any fiscal quarter of the Reporting Entity is
above 3:00 to 1:00 until the first day of the first calendar month after the date upon which the Reporting Entity has delivered the financial statements pursuant to Sections 7.1(a) and 7.1(b) of the Note Purchase Agreement and the
officer’s certificate pursuant to Section 7.2(a) of the Note Purchase Agreement evidencing that the ratio of Consolidated Total Debt to Consolidated EBITDA as of the last day of any fiscal quarter of the Reporting Entity is
equal to or less than 3:00 to 1:00; provided that the applicable rate of interest per annum of this Note set forth in clause (a) and (b) of the first paragraph of this Note shall be increased by 0.75% per annum effective as of
the first day of the first calendar month after the date upon which the Reporting Entity fails to deliver the financial statements required pursuant to Sections 7.1(a) and 7.1(b) of the Note Purchase Agreement and the officer’s
certificate required pursuant to Section 7.2(a) of the Note Purchase Agreement, in each case, on or prior to the end of the month in which occurs the applicable 

  
 EXHIBIT 1-A 
 (to Note Purchase Agreement) 

 
deadline specified in the Note Purchase Agreement for such delivery, until the delivery thereof, and beginning on the date of such delivery, the applicable rate of interest per annum shall be
based on the ratio of Consolidated Total Debt to Consolidated EBITDA reflected in such financial statements and officer’s certificate. 

Notwithstanding the foregoing, during the period from and after the Synergy Closing Date to and until the first day of the first calendar
month after the date upon which the Reporting Entity has delivered the financial statements pursuant to Section 7.1(a) and 7.1(b) of the Note Purchase Agreement and the officer’s certificate pursuant to
Section 7.2(a) of the Note Purchase Agreement with respect to the first full fiscal quarter ending after the Synergy Closing Date, the applicable rate of interest per annum of this Note shall be as set forth in clause (a) and
(b) of the first paragraph of this Note. 
 Payments of principal of, interest on and any
Make-Whole Amount with respect to this Note are to be made in lawful money of the United States of America at Bank of New York in New York, New York or at such other place as the Company shall
have designated by written notice to the holder of this Note as provided in the Note Purchase Agreement referred to below. 
 This Note is
one of the 3.45% Senior Notes, Series A-1, due May 14, 2025 (the “Series A-1 Notes”) of the Company in the aggregate principal amount of
$125,000,000 which, together with the Company’s, $125,000,000 aggregate principal amount 3.55% Senior Notes, Series A-2, due May 14, 2027 (the
“Series A-2 Notes”) and $100,000,000 aggregate principal amount 3.70% Senior Notes, Series A-3, due May 14, 2030 (the “Series A-3 Notes”; the Series A-1 Notes, the Series A-2 Notes and the
Series A-3 Notes being hereinafter referred to collectively as the “Series A Notes”) outstanding under that Note Purchase Agreement, dated as of May 15, 2015 (as from time to
time amended, amended and restated or supplemented, the “Note Purchase Agreement”), between the Company and the Purchasers named therein, is entitled to the benefits thereof together with additional Series of Notes from time to time
issued thereunder (the “Supplemental Notes,” and collectively with the Series A Notes, the “Notes”). Each holder of this Note will be deemed, by its acceptance hereof, (i) to have agreed to the
confidentiality provisions set forth in Section 20 of the Note Purchase Agreement and (ii) to have made the representation set forth in Section 6.1 and Section 6.2 and (iii) to have agreed to the
covenants and agreements of the holders set forth in the Note Purchase Agreement. 
 This Note is a registered Note and, as provided in the

(1) extend in whole or in part (by renewal or otherwise), modify, change, compromise, release or extend the duration of the
time for the performance or payment of any Debt, liability or obligation of the Company or of any other Person secondarily or otherwise liable for any Debt, liability or obligations of the Company on the Notes, or waive any Default with respect
thereto, or waive, modify, amend or change any provision of any other agreement or this Guaranty; or 
 (2) sell, release,
surrender, modify, impair, exchange or substitute any and all property, of any nature and from whomsoever received, held by, or for the benefit of, any such Holder as direct or indirect security for the payment or performance of any Debt, liability
or obligation of the Company or of any other Person secondarily or otherwise liable for any Debt, liability or obligation of the Company on the Notes; or 

(3) settle, adjust or compromise any claim of the Company against any other Person secondarily or otherwise liable for any
Debt, liability or obligation of the Company on the Notes. 

  
 E-2.2(a)-5 

 Each Guarantor hereby ratifies and confirms any such extension, renewal, change, sale, release,
waiver, surrender, exchange, modification, amendment, impairment, substitution, settlement, adjustment or compromise and that the same shall be binding upon it, and hereby waives, to the fullest extent permitted by law, any and all defenses,
counterclaims or offsets which it might or could have by reason thereof, it being understood that such Guarantor shall at all times be bound by this Guaranty and remain liable hereunder. 

(b) Each Guarantor hereby waives, to the fullest extent permitted by law: 

(1) notice of acceptance of this Guaranty by the Holders or of the creation, renewal or accrual of any liability of the
Company, present or future, or of the reliance of such Holders upon this Guaranty (it being understood that every Debt, liability and obligation described in Section 2 hereof shall conclusively be presumed to have been created,
contracted or incurred in reliance upon the execution of this Guaranty); 
 (2) demand of payment by any Holder from the
Company or any other Person indebted in any manner on or for any of the Debt, liabilities or obligations hereby guaranteed; and 

(3) presentment for the payment by any Holder or any other Person of the Notes or any other instrument, protest thereof and
notice of its dishonor to any party thereto and to such Guarantor. 
 The obligations of each Guarantor under this Guaranty and the rights
of any Holder to enforce such obligations by any proceedings, whether by action at law, suit in equity or otherwise, shall not be subject to any reduction, limitation, impairment or termination (other than by payment in full of the Notes and the
obligations of the Company under the Note Purchase Agreement), whether by reason of any claim of any character whatsoever or otherwise and shall not be subject to any defense, set-off, counterclaim (other than
any compulsory counterclaim), recoupment or termination whatsoever. 
 (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: 
 (1) the genuineness, validity, regularity or
enforceability of the Notes, the Note Purchase Agreement or any other agreement or any of the terms of any thereof, the continuance of any obligation on the part of the Company, any other Guarantors or any

  
 E-2.2(a)-6 

 
other Person on or in respect of the Notes or under the Note Purchase Agreement or any other agreement or the power or authority or the lack of power or authority of the Company to issue the

continuance of the Company or any other Person as a legal entity; or

otherwise, in the performance by the Company, any other Guarantor or any other Person of any obligations of any kind or character whatsoever under the Notes, the Note Purchase Agreement, this Guaranty or any other agreement; or

any other Person or in respect of the property of the Company, any other Guarantor or any other Person or any merger, consolidation, reorganization, dissolution, liquidation, the sale of all or substantially all of the assets of or winding up of the
Company, any other Guarantor or any other Person; or 
 (4) impossibility or illegality of performance on the part of the
Company, any other Guarantor or any other Person of its obligations under the Notes, the Note Purchase Agreement, this Guaranty or any other agreements; or

declared), civil commotion, acts of God or the public enemy, delays or failure of suppliers or carriers, inability to obtain materials, action of any Federal or state regulatory body or agency, change of law or any other causes affecting
performance, or any other force majeure, whether or not beyond the control of the Company, any other Guarantors or any other Person and whether or not of the kind hereinbefore specified; or 

(6) any attachment, claim, demand, charge, Lien, order, process, encumbrance or any other happening or event or reason, similar
or dissimilar to the foregoing, or any withholding or diminution at the source, by reason of any taxes, assessments, expenses, Debt, obligations or liabilities of any character, foreseen or unforeseen, and whether or not valid, incurred by or
against the Company, any Guarantor or any other Person or any claims, demands, charges or Liens of any nature, foreseen or unforeseen, incurred by the Company, any Guarantor or any other Person, or against any sums payable in respect of the Notes or
under the Note Purchase Agreement or this Guaranty, so that such sums would be rendered inadequate or would be unavailable to make the payments herein provided; or

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

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 
 (10) the acceptance of any additional security or other guaranty, the advance of additional money
to the Company or any other Person, the renewal or extension of the Notes or amendments, modifications, consents or waivers with respect to the Notes, the Note Purchase Agreement or any other agreement, or the sale, release, substitution or exchange
of any security for the Notes; or 
 (11) any merger or consolidation of the Company, any other Guarantor or any other Person
into or with any other Person or any sale, lease, transfer or other disposition of any of the assets of the Company, any other Guarantor or any other Person to any other Person, or any change in the ownership of any shares of the Company, any other
Guarantor or any other Person; or 
 (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 
 (14) any
other circumstance which might otherwise constitute a defense available to, or a discharge of, any Guarantor or any other Person in respect of the obligations of any Guarantor or other Person under this Guaranty or any other agreement, other than
the defense of indefeasible payment in full in cash of the Notes; 

  
 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. 

  
 E-2.2(a)-11 

	SECTION 7.	PAYMENTS FREE AND CLEAR OF TAXES. 

(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. 
 (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 

  
 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.

form.
