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 30 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

Amount as of the specified prepayment date.

 -19- 

			
	 STERIS CORPORATION

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 

  

 -20- 

			
	 STERIS CORPORATION
	  	NOTE PURCHASE AGREEMENT

  

 
respect to such Called Principal, in accordance with accepted financial practice and at a discount factor (applied on the same periodic basis as that on
which interest on the Notes is payable) equal to the Reinvestment Yield with respect to such Called Principal. 
  
 “Reinvestment Yield” means, with respect to the Called Principal of any Note, 0.50% over the yield to maturity implied by
(a) the yields reported, as of 10:00 A.M. (New York City time) on the second Business Day preceding the Settlement Date with respect to such Called Principal, on the display designated as “Page USD” of the Bloomberg Financial Markets
Services Screen (or, if not available, any other national recognized trading screen reporting on-line intraday trading in the U.S. Treasury securities) for actively traded on-the-run U.S. Treasury securities having a maturity equal to the Remaining
Average Life of such Called Principal as of such Settlement Date, or (b) if such yields are not reported as of such time or the yields reported as of such time are not ascertainable, the Treasury Constant Maturity Series Yields reported, for the
latest day for which such yields have been so reported as of the second Business Day preceding the Settlement Date with respect to such Called Principal, in Federal Reserve Statistical Release H.15 (519) (or any comparable successor publication) for
actively traded on-the-run U.S. Treasury securities having a constant maturity equal to the Remaining Average Life of such Called Principal as of such Settlement Date. Such implied yield will be determined, if necessary, by (i) converting U.S.
Treasury bill quotations to bond-equivalent yields in accordance with accepted financial practice and (ii) interpolating linearly between (1) the actively traded on-the-run U.S. Treasury security with the maturity closest to and greater than the
Remaining Average Life and (2) the actively traded on-the-run U.S. Treasury security with the maturity closest to and less than the Remaining Average Life. 
  
 “Remaining Average Life” means, with respect to any Called Principal, the number of years (calculated to the nearest
one-twelfth year) obtained by dividing (a) such Called Principal into (b) the sum of the products obtained by multiplying (i) the principal component of each Remaining Scheduled Payment with respect to such Called Principal by (ii) the number of
years (calculated to the nearest one-twelfth year) that will elapse between the Settlement Date with respect to such Called Principal and the scheduled due date of such Remaining Scheduled Payment. 
  
 “Remaining Scheduled Payments” means, with
respect to the Called Principal of any Note, all payments of such Called Principal and interest thereon that would be due after the Settlement Date with respect to such Called Principal if no payment of such Called Principal were made prior to its
scheduled due date; provided that if such Settlement Date is not a date on which interest payments are due to be made under the terms of the Notes, then the amount of the next succeeding scheduled interest payment will be reduced by the
amount of interest accrued to such Settlement Date and required to be paid on such Settlement Date pursuant to Section 8.2 or 12.1. 
  
 “Settlement Date” means, with respect to the Called Principal of any Note, the date on which such Called Principal is to
be prepaid pursuant to Section 8.2 or has become or is declared to be immediately due and payable pursuant to Section 12.1, as the context requires.

expected, individually or in the aggregate, to have a Material Adverse Effect. 
  
 Section 9.2. Insurance. The Company will, and will cause each of its Restricted Subsidiaries to, maintain, with financially sound and reputable insurers, insurance with respect to their respective properties

Company 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 Company has concluded that such discontinuance would not,

appropriate proceedings, and the Company or a Restricted Subsidiary has established adequate reserves therefor in accordance with GAAP on the books of the Company or such Subsidiary or (b) the nonpayment of all such taxes and assessments in the

outstanding may at any time at its or their option, by notice or notices to the Company, declare all the Notes then outstanding to be immediately due and payable.

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 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 the Notes then outstanding, 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

 SECTION 13. REGISTRATION; EXCHANGE;
SUBSTITUTION OF NOTES. 
  
 Section 13.1. Registration of Notes. The Company shall keep at its principal executive office a register for the registration and registration of transfers of Notes. The name and address of each holder of one or more Notes, each
transfer thereof and the name and address of each transferee of one or more Notes shall be registered in such register. Prior to due presentment for registration of transfer, the Person in whose name any Note shall be registered shall be deemed and
treated as the owner and holder thereof for all purposes hereof, and the Company shall not be affected by any notice or knowledge to the contrary. The Company shall give to any holder of a Note that is an Institutional Investor promptly upon request
therefor, a complete and correct copy of the names and addresses of all registered holders of Notes. 
  
 Section 13.2. Transfer and Exchange of Notes. Subject to compliance with applicable law, upon surrender of any Note at the principal executive
office of the Company for registration of transfer or exchange (and in the case of a surrender for registration of transfer, duly endorsed or accompanied by a written instrument of transfer duly executed by the registered holder 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 or Exhibit 1.2, as the case may be. Each such new Note shall be dated and bear interest from the date to which interest
shall have been paid on the surrendered Note or dated the date of the surrendered Note if no interest shall have been paid thereon. The Company may require payment of a sum sufficient to cover any stamp tax or governmental charge imposed in respect
of any such transfer of Notes. Notes shall not be transferred in denominations of less than $100,000; provided that if necessary to enable the registration of transfer by a holder of its entire holding of Notes, one Note may be in a
denomination of less than $100,000. Any transferee, by its acceptance of a Note registered in its name (or the name of its nominee), shall be deemed to have made the representations set forth in Section 6.1 and Section 6.2. 

 
 Section 13.3. Replacement of Notes. Upon receipt by the Company of
evidence reasonably satisfactory to it of the ownership of and the loss, theft, destruction or mutilation of any Note (which evidence shall be, in the case of an Institutional Investor, notice from such Institutional Investor of such ownership and
such loss, theft, destruction or 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 
  
 (b) in the case of mutilation, upon surrender and cancellation thereof, 
  

 -35- 

			
	 STERIS CORPORATION
	  	NOTE PURCHASE AGREEMENT

  

 the Company at its own expense shall execute and deliver, in lieu thereof, a new Note of the same Series (and of the
same tranche if such Series has separate tranches), dated and bearing interest from the date to which interest shall have been paid on such lost, stolen, destroyed or mutilated Note or dated the date of such lost, stolen, destroyed or mutilated Note
if no interest shall have been paid thereon. 
  
 SECTION 14. PAYMENTS ON NOTES. 
  
 Section 14.1. Place of Payment. Subject to Section 14.2, payments of principal, Make-Whole Amount, if any, and interest becoming due and
payable on the Notes shall be made in New York, New York at the principal office of Bank of New York in such jurisdiction. The Company may at any time, by notice to each holder of a Note, change the place of payment of the Notes so long as such
place of payment shall be either the principal office of the Company in such jurisdiction or the principal office of a bank or trust company in such jurisdiction. 
  
 Section 14.2. Home Office Payment. So long as you or your nominee shall be the holder of any Note, and
notwithstanding anything contained in Section 14.1 or in such Note to the contrary, the Company will pay all sums becoming due on such Note for principal, Make-Whole Amount, if any, and interest by the method and at the address specified for
such purpose below your name in Schedule A or in a Supplemental Note Purchase Agreement, as the case may be, or by such other method or at such other address as you 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, you
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 you or your nominee you will, at your 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 you under this Agreement and that has made the same agreement relating to such Note as you have made in this Section 14.2. 
  
 SECTION 15. EXPENSES, ETC. 
  
 Section 15.1. Transaction Expenses. (a) Whether or not the transactions contemplated hereby are consummated, the
Company will pay all costs and expenses (including reasonable attorneys’ fees of a special counsel and, if reasonably required, local or other counsel) incurred by you and each Other Purchaser or holder of a Note in connection with such
transactions and in connection with any amendments, waivers or consents under or in respect of this Agreement (and/or any Supplemental Note Purchase Agreement), the Notes, any Security Document or the Intercreditor Agreement (whether or not such

harmless from, all claims in respect of any fees, costs or expenses, if any, of brokers and finders (other than those retained by you).

 SECTION 16. SURVIVAL
OF REPRESENTATIONS AND WARRANTIES; ENTIRE AGREEMENT. 
  
 All representations and warranties contained herein shall survive the execution and delivery of this Agreement (including any Supplemental Note Purchase
Agreement) and the Notes, the purchase or transfer by you of any Note or portion thereof or interest therein and the payment of any Note, and may be relied upon by any subsequent holder of a Note, regardless of any investigation made at any time by

under this Agreement. Subject to the preceding sentence, this Agreement and any Supplemental Note Purchase Agreement and the Notes embody the entire agreement and understanding between you and the Company and supersede all prior agreements and

 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 you unless consented to by you 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) The Collateral Documents may be amended in the manner prescribed in the Intercreditor Agreement, and the Subsidiary Guaranty and the Intercreditor
Agreement may be amended in the manner prescribed in each such document, and all amendments to the Security Documents and the Intercreditor Agreement 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 or the Intercreditor Agreement. 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 or the Intercreditor Agreement 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. The Company will not 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 Notes of any waiver or amendment of any of the terms and provisions hereof 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.

 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, any
Security Document or the Intercreditor Agreement, or have directed the taking of any action provided herein or in the Notes, any Security Document or the Intercreditor Agreement 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.

administrative proceeding (whether or not the original is in existence and whether or not such reproduction was made by you 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 you by or on behalf of the Company 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 you as being confidential information
of the Company or such Subsidiary; provided that such term does not include information that (a) was publicly known or otherwise known to you prior to the time of such disclosure, (b) subsequently becomes publicly known through no act or
omission by you or any Person acting on your behalf, (c) otherwise becomes known to you other than through disclosure by the Company or any Subsidiary or any other holder of any Note, (d) constitutes financial statements delivered to you 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 you 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. You will maintain the confidentiality of such Confidential Information in accordance with reasonable procedures adopted by you in good faith to protect confidential information of third parties delivered to you;
provided that you may deliver or disclose Confidential Information to (i) your 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 your Notes), (ii) your 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 you sell or offer 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), (v) any Person from which you offer to purchase any
security of the Company (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 you
to the extent required, (vii) the National Association of Insurance Commissioners or any similar organization, or any nationally recognized rating agency that requires access to information about your investment portfolio to the extent required 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 you, (x) in response to any subpoena or other legal process, (y) in connection with any
litigation to which you are a party or (z) if an Event of Default has occurred and is continuing, to the extent you 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 your 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. 
  
 You shall have the right to substitute any one of your Affiliates as the purchaser of the Notes that you have agreed to purchase hereunder, by written notice to the Company, which notice shall be signed by both you
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, wherever the word “you” is used in this Agreement (other than in this Section 21), such word shall be deemed to refer to such Affiliate in lieu of you. In the event that such Affiliate is so substituted as a
purchaser hereunder and such Affiliate thereafter transfers to you all of the Notes then held by such Affiliate, upon receipt by the Company of notice of such transfer, wherever the word “you” is used in this Agreement (other than in this
Section 21), such word shall no longer be deemed to refer to such Affiliate, but shall refer to you, and you shall 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 Company for the purposes of this Agreement, the same shall be done by the Company in accordance
with GAAP, to the extent applicable, except where such principles are inconsistent with the requirements of this Agreement. 
  
 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 Company hereby 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 Agreement and the Notes may be litigated in such courts, 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 Company at the address set forth in Section 18) and that service so made shall be deemed to be completed upon
actual receipt. The Company hereby irrevocably appoints

jurisdiction against the Company 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.
