specified in Section 4 shall not have been fulfilled to such Purchaser’s satisfaction, such Purchaser shall, at its election, be relieved of all further obligations under this Agreement, without thereby waiving any rights such Purchaser
may have by reason of such failure or such nonfulfillment. 
 SECTION 4.
CONDITIONS TO CLOSING. 
 Each Purchaser’s obligation to purchase and
pay for the Notes to be sold to such Purchaser at the Closing is subject to the fulfillment to such Purchaser’s satisfaction, prior to or at the Closing, of the following conditions:

the application of the proceeds thereof as contemplated by Section 5.14) no Default or Event of Default shall have occurred and be continuing. Neither the Company nor any Subsidiary shall have entered into any transaction since the date of the
Presentation that would have been prohibited by Section 10.1, 10.5, 10.6 or 10.7 had such Sections applied since such date.

T, U or X of the Board) and (c) not subject such Purchaser to any tax, penalty or liability under or pursuant to any applicable law or regulation, which law or regulation was not in effect on the date hereof. If requested by such Purchaser,
such Purchaser shall have received an Officer’s Certificate certifying as to such matters of fact as such Purchaser may reasonably specify to enable such Purchaser to determine whether such purchase is so permitted. 

Section 4.6. Sale of Other Notes. Contemporaneously with the Closing the Company shall sell to each other

Section 4.7. Payment of Special Counsel Fees. Without limiting the provisions of Section 15.1, the

 Section 4.9. Changes in Corporate Structure. No Obligor
shall have changed its jurisdiction of incorporation or organization, as applicable, or been a party to any merger or consolidation or succeeded to all or any substantial part of the liabilities of any other entity, at any time following the date of
the most recent financial statements referred to in Section 5.5 except in a transaction wherein, the resulting entities shall be organized under the laws of the United States or any state thereof and such transaction would have been permitted

transferee bank, (ii) such transferee bank’s ABA number and (iii) the account name and number into which the purchase price for the Notes is to be deposited. Each Purchaser has the right, but not the obligation, upon written notice
(which may be by email) to the Company, to elect to deliver a micro deposit (less than $50.00) to the account identified in the written instructions no later than two (2) Business Days prior to Closing. If a Purchaser delivers a micro
deposit, a Responsible Officer must verbally verify the receipt and amount of the micro deposit to such Purchaser on a telephone call initiated by such Purchaser prior to Closing. The Company shall not be obligated to return the amount of the
micro deposit, nor will the amount of the micro deposit be netted against the Purchaser’s purchase price of the Notes.

OF THE COMPANY.,

Company represents and warrants to each Purchaser that: 
 Section 5.1. Organization; Power and Authority.
The Company is a corporation duly organized, validly existing and in good standing under the laws of its jurisdiction of incorporation, and is duly qualified as a foreign corporation and is in good standing in each jurisdiction in which such
qualification is required by law, other than those jurisdictions as to which the failure to be so qualified or in good standing could not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect. The Company has
the corporate 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, except where the failure to have such corporate power or authority
could not reasonably be expected to have a Material Adverse Effect. The Company has the corporate power and authority to execute and deliver this Agreement and the Notes and to perform the provisions hereof and thereof.

	Waters Corporation	  	Note Purchase Agreement

  

 Section 5.2. Authorization, Etc. This Agreement and the
Notes have been duly authorized by all necessary corporate action on the part of the Company, and this Agreement constitutes, and upon execution and delivery thereof each Note will constitute, a legal, valid and binding obligation of the Company
enforceable against the Company in accordance with its terms, except as such enforceability may be limited by (i) applicable bankruptcy, insolvency, reorganization, moratorium or other similar laws affecting the enforcement of creditors’
rights generally and (ii) general principles of equity (regardless of whether such enforceability is considered in a proceeding in equity or at law). 

Section 5.3. Disclosure. The Company, through its agents, MUFG Securities Americas Inc. and U.S. Bancorp
Investments, Inc., has delivered to each Purchaser a copy of a Private Placement Investor Presentation dated November 5, 2020 (the “Presentation”), relating to the transactions contemplated hereby. The Presentation provides an
overview of recent corporate events and other selected Company information. This Agreement, the Presentation, the financial statements listed in Schedule 5.5 and the documents, certificates or other writings delivered to the Purchasers by or on
behalf of the Company in connection with the transactions contemplated hereby and identified in Schedule 5.3 and the financial statements described in Section 5.5 (this Agreement, the Presentation and such documents, certificates or other
writings, and such financial statements delivered to each Purchaser prior to November 19, 2020 being referred to, collectively, as the “Disclosure Documents”), taken as a whole, do not contain any untrue statement of a material
fact or omit to state any material fact necessary to make the statements therein not misleading in light of the circumstances under which they were made provided, that with respect to projected financial information, the Company represents
only that such information was prepared in good faith based upon assumptions believed to be reasonable at the time. Except as disclosed in the Disclosure Documents, since December 31, 2019, there has been no change in the financial condition,
operations, business, properties or prospects of the Company or any Subsidiary except changes that individually or in the aggregate could not reasonably be expected to have a Material Adverse Effect. There is no fact known to the Company that could
reasonably be expected to have a Material Adverse Effect that has not, been set forth herein or in the Disclosure Documents. 

Section 5.4. Organization and Ownership of Shares of Subsidiaries; Affiliates. (a) Schedule 5.4
contains (except as noted therein) complete and correct lists (i) of the Company’s Subsidiaries, showing, as to each Subsidiary, the correct name thereof, the jurisdiction of its organization, the percentage of shares of each class of its
capital stock or similar equity interests outstanding owned by the Company and each other Subsidiary and whether such Subsidiary is a Guarantor, (ii) to the knowledge of the Company, of the Company’s Affiliates, other than Subsidiaries,
and (iii) of the Company’s directors and senior officers. 
 (b) All of the outstanding shares of capital stock or similar equity
interests of each Subsidiary shown in Schedule 5.4 as being owned by the Company and its Subsidiaries have been validly issued, are, in the case of Domestic Subsidiaries, fully paid and nonassessable and, in all cases, are owned by the Company
or another Subsidiary free and clear of any Lien other than a Lien which would not be prohibited by Section 10.5.

	Waters Corporation	  	Note Purchase Agreement

  

 (c) Each Subsidiary identified in Schedule 5.4 is a corporation or other legal entity
duly organized, validly existing and in good standing under the laws of its jurisdiction of organization, and is duly qualified as a foreign corporation or 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 could not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect. Each such Subsidiary has the
corporate or other power and authority to own or hold under lease the properties it purports to own or hold under lease and to transact the business it transacts and proposes to transact except where the failure to have such corporate or other power
and authority could not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect. 
 (d) No Subsidiary is
a party to, or otherwise subject to any Material legal, Material regulatory, contractual or other restriction (other than this Agreement, the agreements listed on Schedule 5.4 and customary limitations imposed by corporate law or similar
statutes) restricting the ability of such Subsidiary to pay dividends out of profits or make any other similar distributions of profits to the Company or any of its Subsidiaries that owns outstanding shares of capital stock or similar equity
interests of such Subsidiary except for restrictions contained in agreements or contracts which would be permitted by the provisions of Section 10.8. 

Section 5.5. Financial Statements; Material Liabilities. The Company has delivered to each Purchaser copies
of the financial statements of the Company and its consolidated Subsidiaries for the fiscal year ended December 31, 2019. All of said financial statements (including in each case the related schedules and notes) fairly present in all material

 Section 5.12. Compliance with

transaction that is subject to the prohibitions of section 406 of ERISA or in connection with which a tax could be imposed pursuant to section 4975(c)(1)(A)-(D) of the Code. The representation by the
Company to each Purchaser in the first sentence of this Section 5.12(d) is made in reliance upon and subject to the accuracy of such Purchaser’s representation in Section 6.2 as to the sources of the funds to be used to pay the

any Securities under such circumstances as to involve the Company in a violation of Regulation X of said Board (12 CFR 224) or to involve any broker or dealer in a violation of Regulation T of said Board (12 CFR 220). Margin
stock does not constitute more than 5.00% of the value of the consolidated assets of the Company and its Subsidiaries and the Company does not have any present intention that margin stock will constitute more than 5.00% of the value of such assets.

Subsidiaries. Neither the Company nor any Subsidiary is in default and no waiver of default is currently in effect, in the payment of any principal or interest on any Debt of the Company or such Subsidiary which, individually, relates to a committed
or outstanding principal amount of not less than $30,000,000 and no event or condition exists with respect to any such Debt of the Company or any Subsidiary that would permit (or that with notice or the lapse of time, or both, would permit) one or
more Persons to cause such Debt to become due and payable before its stated maturity or before its regularly scheduled dates of payment.

 Section 8.4. Maturity; Surrender, Etc. In the case of
each prepayment of Notes 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 (which shall be a Business Day), together with interest on such

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 Controlled Affiliate to purchase, redeem, prepay or otherwise acquire, directly or indirectly, any of the outstanding Notes except (a) upon the payment or prepayment of the
Notes in accordance with the terms of this Agreement and the Notes or (b) pursuant to an offer to purchase made by the Company or a Controlled Affiliate pro rata to the holders of all Notes 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 20 Business Days. If the holders of more than 25% of the
principal amount of the Notes 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 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 Controlled Affiliate pursuant to any payment,
prepayment or purchase of Notes pursuant to any provision of this Agreement and no Notes may be issued in substitution or exchange for any such Notes. 

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. 

  
 -18- 















			
	Waters Corporation	  	Note Purchase Agreement

  

 Reinvestment Yield” means, with respect to the Called Principal of any Note, the
sum of (a) 0.50% plus (b) the yield to maturity implied by the “Ask-Yield(s)” 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” (or such other display as may replace Page PX1) on Bloomberg Financial Markets for the most recently issued actively traded on-the-run U.S. Treasury securities (“Reported”) having a maturity equal to the Remaining Average Life of such Called Principal as of such Settlement Date. If there are no such U.S. Treasury
securities Reported having a maturity equal to such Remaining Average Life, then such implied yield to maturity will be determined by (a) converting U.S. Treasury bill quotations to bond equivalent yields in accordance with accepted financial
practice and (b) interpolating linearly between the “Ask-Yields” Reported for the applicable most recently issued actively traded
on-the-run U.S. Treasury securities with the maturities (1) closest to and greater than such Remaining Average Life and (2) closest to and less than such
Remaining Average Life. The Reinvestment Yield shall be rounded to the number of decimal places as appears in the interest rate of the applicable Note. 

If such yields are not Reported or the yields Reported as of such time are not ascertainable (including by way of interpolation), then
“Reinvestment Yield” means, with respect to the Called Principal of any Note, the sum of (x) 0.50% plus (y) the yield to maturity implied by the U.S. Treasury constant maturity 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 (or any comparable successor publication) for the U.S. Treasury constant
maturity having a term equal to the Remaining Average Life of such Called Principal as of such Settlement Date. If there is no such U.S. Treasury constant maturity having a term equal to such Remaining Average Life, such implied yield to maturity
will be determined by interpolating linearly between (1) the U.S. Treasury constant maturity so reported with the term closest to and greater than such Remaining Average Life and (2) the U.S. Treasury constant maturity so reported with the
term closest to and less than such Remaining Average Life. The Reinvestment Yield shall be rounded to the number of decimal places as appears in the interest rate of the applicable Note. 

“Remaining Average Life” means, with respect to any Called Principal, the number of years obtained by dividing (i) such
Called Principal into (ii) the sum of the products obtained by multiplying (a) the principal component of each Remaining Scheduled Payment with respect to such Called Principal by (b) the number of years, computed on the basis of a 360-day year comprised of twelve 30-day months and calculated to two decimal places, 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 

  
 -19- 















			
	Waters Corporation	  	Note Purchase Agreement

  

 
which interest payments are due to be made under 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 Section 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. The Company will, within five (5) Business Days after the occurrence of any Change in Control,
give written notice (the “Change of Control Notice”) of such Change in Control to each holder of Notes. Such Change of Control Notice shall contain and constitute an offer to prepay the Notes as described in Section 8.7(c)
hereof and shall be accompanied by the certificate described in Section 8.7(e). 
 (b) Offer to Prepay Notes. The offer to prepay
Notes contemplated by paragraph (a) of this Section 8.7 shall be an offer to prepay, in accordance with and subject to this Section 8.3, all, but not less than all, 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 Change of Control Notice (the “Proposed Prepayment Date”). Such date shall be
not less than 30 days and not more than 90 days after the date of such offer. 
 (c) Acceptance. 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 not later than 10 days prior to the Proposed Prepayment Date. A failure by a holder of Notes to respond to
an offer to prepay made pursuant to this Section 8.3 shall be deemed to constitute a rejection of such offer by such holder. 
 (d)
Prepayment. Prepayment of the Notes to be prepaid pursuant to this Section 8.7 shall be at 100% of the principal amount of the Notes together with accrued and unpaid interest thereon but without any
Make-Whole Amount. The prepayment shall be made on the Proposed Prepayment Date.

Control.

that, following the completion of a Material Acquisition that, on a pro forma basis, giving effect to any related incurrence or repayment of Debt, would result in an increase in the Company’s Leverage Ratio, if the Company shall so elect by a
notice delivered to the holders of Notes as of the last day of the fiscal quarter the Material Acquisition was consummated (a “Leverage Ratio Increase Election”), such maximum Leverage Ratio shall be increased to 4.00:1.00 at the
end of and for the fiscal quarter during which such Material Acquisition shall have been consummated and at the end of and for each of the following three consecutive fiscal quarters (the period during which any such increase in the Leverage Ratio
shall be in effect being called a “Leverage Ratio Increase Period”), and in which event, the Company shall be obligated to pay the Incremental Interest Payment provided for in Section 10.9(c). The Company may terminate any
Leverage Ratio Increase Period by a notice delivered to the holders of Notes, whereupon, on the last day of the fiscal quarter during which such notice is given and on the last day of each fiscal quarter thereafter until another Leverage Ratio
Increase Period has commenced as provided in this Section, the maximum Leverage Ratio shall be 3.50:1.00. If a Leverage Ratio Increase Election shall have been made under this Section, the Company may not make another Leverage Ratio Increase
Election unless, following the termination or expiration of the most recent prior Leverage Ratio Increase Period, the Leverage Ratio as of the last day of at least two consecutive full fiscal quarters of the Company shall not have exceeded
3.50:1.00. Notwithstanding the foregoing, the Company shall not be permitted to make more than two Leverage Ratio Increase Elections during the term of this Agreement.

demonstrating that, as of the last day of the fiscal quarter in respect of which such Officer’s Certificate is delivered, the Leverage Ratio is not more than 3.50 to 1.00. In the event such Officer’s Certificate evidencing that the
Leverage Ratio is not more than 3.50 to 1.00 is delivered, the Incremental Interest shall cease to accrue on the last day of the fiscal quarter in respect of which such Officer’s Certificate is delivered. 

(c) Within 10 Business Days of the delivery of an Officer’s Certificate pursuant to Section 7.2(a) evidencing that
the Leverage Ratio exceeds 3.50 to 1.00, the Company shall pay to each holder of a Note the amount attributable to the Incremental Interest (the “Incremental Interest Payment”) which shall be the product of (i) the
aggregate outstanding principal amount of Notes held by such holder (or its predecessor(s) in interest) as of the first day that Incremental Interest begins to accrue, (ii) 0.50% (to reflect the Incremental Interest) and (iii) 0.25% (to reflect
that the Incremental Interest is payable quarterly). The Incremental Interest Payment, if any, shall be paid quarterly by wire transfer of immediately available funds to each holder of the Notes in accordance with the terms of this Agreement.

SECTION 12. REMEDIES ON DEFAULT,
ETC. 
 Section 12.1. Acceleration. (a) If an Event of Default with
respect to the Company described in Section 11(g) or (h) (other than an Event of Default described in clause (i) of Section 11(g) or described in clause (vi) of Section 11(g) by virtue of the fact that such clause
encompasses clause (i) of Section 11(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 50% in principal amount of the Notes at
the time outstanding may at any time at its or their option, by notice or notices to the Company, declare all the Notes then outstanding to be immediately due and payable. 

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

Upon any Notes becoming due and payable under this Section 12.1, whether automatically or by declaration, such Notes will forthwith
mature and the entire unpaid principal amount of such Notes, plus (x) all accrued and unpaid interest thereon (including, but not limited to, interest accrued thereon at the Default Rate) and (y) the
Make-Whole Amount, if any, 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, if any, 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 or in any Note or in any Guarantee Agreement, 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 Section 12.1(b) or (c), 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) neither the Company nor any other Person shall have paid any amounts which have become due solely by reason of such declaration, (c) 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 (d) 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, the Guarantee
Agreement or by any Note 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 expenses of such holder incurred in any enforcement or collection under this Section 12,
including, without limitation, reasonable attorneys’ fees, expenses and disbursements.

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. If any holder of one or more Notes is a nominee, then (a) the name and address of the beneficial owner of such Note or Notes shall also be registered in such register as an owner and
holder thereof and (b) at any such beneficial owner’s option, either such beneficial owner or its nominee may execute any amendment, waiver or consent pursuant to this Agreement. Prior to due presentment for registration of transfer, the
Person(s) in whose name any Note(s) 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

 Section 13.2. Transfer and Exchange of Notes. Upon surrender
of any Note to the Company at the address and to the attention of the designated officer (all as specified in Section 18(iii)), for registration of transfer or exchange (and in the case of a surrender for registration of transfer accompanied by
a written instrument of transfer duly executed by the registered holder of such Note or such holder’s attorney duly authorized in writing and accompanied by the relevant name, address and other information for notices of each transferee of such
Note or part thereof), within ten Business Days thereafter, 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) 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 with respect to the Series N Notes and Exhibit 1-B with respect to the Series O Notes. 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 representation set forth in Section 6.2. If a transferee is relying on
clauses (c), (d), (e) or (g) of Section 6.2, it shall provide the written disclosure required in such clauses to the Company at least six Business Days prior to the transfer of a Note and if the Company reasonably determines, based upon an
opinion of counsel it furnishes to the transferor and the transferee not less than one Business Day prior to the proposed transfer, that the transfer could reasonably be prohibited under section 406 of ERISA, such transfer shall not be
effectuated until such time, if any, as the transferee represents that it is relying on other clauses of Section 6.2 or the Company determines that the proposed transfer would not be prohibited by section 406 of ERISA. 

Section 13.3. Replacement of Notes. Upon receipt by the Company at the address and to the attention of the
designated officer (all as specified in Section 18(iii)) 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 $25,000,000 or a Qualified Institutional Buyer, 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, 

within ten Business Days thereafter, the Company at its own expense shall execute and deliver, in lieu thereof, a new Note, 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.

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, such Purchaser 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 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 same agreement relating to such Note as the Purchasers
have made in this Section 14.2. 
 Section 14.3. FATCA Information. By acceptance of any Note,
the holder of such Note agrees that such holder will with reasonable promptness duly complete and deliver to the Company, or to such other Person as may be reasonably requested by the Company, from time to time (a) in the case of any such
holder that is a United States Person, such holder’s United States tax identification number or other Forms reasonably requested by the Company necessary to establish such holder’s status as a United States Person under FATCA and as may
otherwise be necessary for the Company to comply with its obligations under FATCA and (b) in the case of any such holder that is not a United States Person, such documentation prescribed by applicable law (including as prescribed by
section 1471(b)(3)(C)(i) of the Code) and such additional documentation as may be necessary for the Company to comply with its obligations under FATCA and to determine that such holder has complied with such holder’s obligations under
FATCA or to determine the amount (if any) to deduct and withhold from any such payment made to such holder. Nothing in this Section 14.3 shall require any holder to provide information that is confidential or proprietary to such holder unless
the Company is required to obtain such information under FATCA and, in such event, the Company shall treat any such information it receives as confidential.

AND WARRANTIES; ENTIRE AGREEMENT. 
 All representations and
warranties contained herein shall survive the execution and delivery of this Agreement and the Notes, the purchase or transfer by any Purchaser 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 or on behalf of such Purchaser or any other holder of a Note. All statements contained in any certificate or other instrument delivered by or on behalf of the

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 the Guarantee 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 the Guarantee Agreement to each

 Section 17.3. Binding Effect, Etc. Any amendment or
waiver consented to as provided in this Section 17 or the Guarantee Agreement applies equally to all holders of Notes and is binding upon them and upon each future holder of any Note 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 any holder of any Note and no delay in exercising any rights hereunder or under any Note or Guarantee Agreement shall operate as a waiver of any rights of any holder of such Note. As used herein, the term
“this Agreement” and references thereto shall mean this Agreement as it may from time to time be amended or supplemented. 

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 Guarantee Agreement or the Notes, or have directed the taking of any
action provided herein or in the Guarantee Agreement or the Notes 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

Schedule A, or at such other address as such Purchaser or nominee shall have specified to the Company in writing, 
 (ii) if
to any other holder of any Note, to such holder at such address as such other holder shall have specified to the Company in writing, or

	Waters Corporation	  	Note Purchase Agreement

  

 
Company agrees and stipulates 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 Company or any Subsidiary in connection with the transactions contemplated by or otherwise pursuant to this Agreement 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 not as a result of any violation of this Section 20 which violation was known by such Purchaser, (b) subsequently becomes publicly known
through no act or omission by such Purchaser or any person acting on such Purchaser’s behalf, (c) otherwise becomes known to such Purchaser other than through disclosure by the Company or any Subsidiary not as a result of any violation of
this Section 20 which violation was known by such Purchaser or (d) constitutes financial statements delivered to such Purchaser under Section 7.1 that are otherwise publicly available. Each Purchaser will maintain the confidentiality
of such Confidential Information in accordance with procedures adopted by such Purchaser in good faith to protect confidential information of third parties delivered to such Purchaser, provided that such Purchaser may deliver or disclose
Confidential Information to (i) its directors, officers, employees, agents, attorneys, trustees and affiliates (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), (v) any Person from which it offers 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 such Purchaser, (vii) the NAIC or the SVO or, in each case, any similar organization, or any nationally recognized rating agency that requires access to information
about such Purchaser’s investment portfolio, or (viii) any other Person to which such delivery or disclosure may be necessary or appropriate (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 such Purchaser 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 such Purchaser’s Notes, this Agreement or the Guarantee 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), such holder will enter into an agreement with the
Company embodying the provisions of this Section 20.

	Waters Corporation	  	Note Purchase Agreement

  

 In the event that as a condition to receiving access to information relating to the Company
or its Subsidiaries in connection with the transactions contemplated by or otherwise pursuant to this Agreement, any Purchaser or holder of a Note is required to agree to a confidentiality undertaking (whether through IntraLinks, another secure
website, a secure virtual workspace or otherwise) which is different from this Section 20, this Section 20 shall not be amended thereby and, as between such Purchaser or such holder and the Company, this Section 20 shall supersede any
such other confidentiality undertaking. 
 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 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 by
or on behalf of any of the parties hereto bind and inure to the benefit of their respective successors and assigns (including any subsequent holder of a Note) whether so expressed or not, except that, subject to Section 10.2, the Company may
not assign or otherwise transfer any of its rights or obligations hereunder or under the Notes without the prior written consent of each holder. Nothing in this Agreement, expressed or implied, shall be construed to confer upon any Person (other
than the parties hereto and their respective successors and assigns permitted hereby) any legal or equitable right, remedy or claim under or by reason of this Agreement. 

Section 22.2. Payments Due on Non-Business Days.
Anything in this Agreement or the Notes to the contrary notwithstanding (but without limiting the requirement in Section 8.4 that the notice of any optional prepayment specify a Business Day as the date fixed for such prepayment), 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


  
 -36- 















			
	Waters Corporation	  	Note Purchase Agreement

  

 
without including the additional days elapsed in the computation of the interest payable on such next succeeding Business Day; provided that if the maturity date of any Note is a date other than
a Business Day, the payment otherwise due on such maturity date shall be made on the next succeeding Business Day and shall include the additional days elapsed in the computation of interest payable on such next succeeding Business Day. 

Section 22.3. Accounting Terms. (a) All accounting terms used herein which are not expressly
defined in this Agreement have the meanings respectively given to them in accordance with GAAP. Except as otherwise specifically provided herein, (i) all computations made pursuant to this Agreement shall be made in accordance with GAAP, and
(ii) all financial statements shall be prepared in accordance with GAAP. 
 (b) If the Company notify the holders of Notes that, in the
Company’s reasonable opinion, or if the Required Holders notify the Company that, in the Required Holders’ reasonable opinion, as a result of changes in applicable GAAP after the date of this Agreement (“Subsequent
Changes”), any of the covenants contained in Sections 10.5 through 10.10, inclusive, or any of the defined terms used therein no longer apply as intended such that such covenants are materially more or less restrictive to the
Company than as at the date of this Agreement, the Company and the holders of Notes shall negotiate in good faith to reset or amend such covenants or defined terms so as to negate such Subsequent Changes, or to establish alternative covenants or
defined terms. Until the Company and the Required Holders so agree to reset, amend or establish alternative covenants or defined terms, the covenants contained in Sections 10.5 through 10.10, inclusive, together with the relevant defined terms,
shall continue to apply and compliance therewith shall be determined assuming that the Subsequent Changes shall not have occurred (“Static GAAP”). During any period that compliance with any covenants shall be
determined pursuant to Static GAAP, the Company shall include relevant reconciliations in reasonable detail between then applicable GAAP and Static GAAP with respect to the applicable covenant compliance calculations contained in each certificate of
a Senior Financial Officer delivered pursuant to Section 7.2(a) during such period. 
 (c) Without limiting the foregoing, leases shall
continue to be classified and accounted for on a basis consistent with that reflected in the financial statements of the Company and its consolidated Subsidiaries for the fiscal year ended December 31, 2018 for all purposes of this Agreement,
notwithstanding any change in GAAP relating thereto, unless the parties hereto shall enter into a mutually acceptable amendment addressing such changes, as provided for above. For the avoidance of doubt, the Company shall include relevant
reconciliations in reasonable detail between GAAP in place at the applicable time to GAAP in place (related to such treatment of leases) for the fiscal year ended December 31, 2018 with respect to the applicable covenant compliance calculations
contained in each certificate of Senior Financial Officer delivered pursuant to Section 7.2(a) during such period. Notwithstanding the foregoing, in the event that the Primary Credit Agreement is amended or modified with the effect that any
provision (including but not limited to the leverage covenant contained therein) shall include a lease of property of a Person as lessee as debt for purposes of such provision (notwithstanding that such lease would not have been included as debt
under GAAP as in effect on December 31, 2018), then such lease shall be included as a Capital Lease under this Agreement.

 Section 22.4. 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 22.5. Construction, Etc. 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. 

Defined terms herein shall apply equally to the singular and plural forms of the terms defined. Whenever the context may require, any pronoun
shall include the corresponding masculine, feminine and neuter forms. The words “include,” “includes” and “including” shall be deemed to be followed by the phrase “without limitation.” The word
“will” shall be construed to have the same meaning and effect as the word “shall.” Unless the context requires otherwise (a) any definition of or reference to any agreement, instrument or other document herein shall be
construed as referring to such agreement, instrument or other document as from time to time amended, supplemented or otherwise modified (subject to any restrictions on such amendments, supplements or modifications set forth herein) and, for purposes
of the Notes, shall also include any such notes issued in substitution therefor pursuant to Section 13, (b) subject to Section 22.1, any reference herein to any Person shall be construed to include such Person’s successors and
assigns, (c) the words “herein,” “hereof” and “hereunder,” and words of similar import, shall be construed to refer to this Agreement in its entirety and not to any particular provision hereof, (d) all
references herein to Sections and Schedules shall be construed to refer to Sections of, and Schedules to, this Agreement, and (e) any reference to any law or regulation herein shall, unless otherwise specified, refer to such law or regulation
as amended, modified or supplemented from time to time. 
 For the avoidance of doubt, all Schedules and Exhibits attached to this Agreement shall be deemed
to be a part hereof. 
 Section 22.6. Counterparts; Electronic Contracting. 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. The parties agree to electronic contracting and signatures with respect to this Agreement. Delivery of an electronic signature to, or a signed copy of, this Agreement by email or other electronic transmission shall be fully binding
on the parties to the same extent as the delivery of the signed originals and shall be admissible into evidence for all purposes. 

Section 22.7. 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 permit the
application of the laws of a jurisdiction other than such State.

Trial. (a) The Company irrevocably submits to the non-exclusive jurisdiction of any New York State or federal court sitting in the Borough of Manhattan, The City of New York, over any
suit, action or proceeding arising out of or relating to this Agreement or the Notes. To the fullest extent permitted by applicable law, the Company irrevocably waives and agrees not to assert, by way of motion, as a defense or otherwise, any claim
that it is not subject to the jurisdiction of any such court, any objection that it may now or hereafter have to the laying of the venue of any such suit, action or proceeding brought in any such court and any claim that any such suit, action or
proceeding brought in any such court has been brought in an inconvenient forum. 
 (b) The Company agrees, to the fullest extent permitted by
applicable law, that a final judgment in any suit, action or proceeding of the nature referred to in Section 22.7(a) brought in any such court shall be conclusive and binding upon it subject to rights of appeal, as the case may be, and may be
enforced in the courts of the United States of America or the State of New York (or any other courts to the jurisdiction of which it or any of its assets is or may be subject) by a suit upon such judgment. 

(c) The Company consents to process being served by or on behalf of any holder of Notes in any suit, action or proceeding of the nature
referred to in Section 22.8(a) by mailing a copy thereof by registered, certified, priority or express mail (or any substantially similar form of mail), postage prepaid, return receipt or delivery confirmation requested, to it at its address
specified in Section 18 or at such other address of which such holder shall then have been notified pursuant to said Section. The Company agrees that such service upon receipt (i) shall be deemed in every respect effective service of
process upon it in any such suit, action or proceeding and (ii) shall, to the fullest extent permitted by applicable law, be taken and held to be valid personal service upon and personal delivery to it. Notices hereunder shall be conclusively
presumed received as evidenced by a delivery receipt furnished by the United States Postal Service or any reputable commercial delivery service. 

(c) Nothing in this Section 22.8 shall affect the right of any holder of a Note to serve process in any manner permitted by law, or limit
any right that the holders of any of the Notes may have to bring proceedings against the Company in the courts of any appropriate jurisdiction or to enforce in any lawful manner a judgment obtained in one jurisdiction in any other jurisdiction. 

(d) THE PARTIES HERETO HEREBY WAIVE TRIAL
BY JURY IN ANY ACTION BROUGHT ON OR WITH RESPECT TO THIS
AGREEMENT, THE NOTES OR ANY OTHER DOCUMENT EXECUTED IN CONNECTION HEREWITH
OR THEREWITH.

contrary provision herein or in the Notes or in any Guarantee Agreement, if the Company shall request the release under a Guarantee Agreement (x) of any Subsidiary to be sold or otherwise disposed of (including through the sale or disposition
of any Subsidiary owning such Subsidiary) to a Person other than the Company or a Subsidiary in a transaction permitted under the terms of this Agreement or (y) of any Subsidiary because such Subsidiary has become an Excluded Subsidiary, and,
in other

Excluded Subsidiary will comply with the terms of this Agreement, (ii) such Subsidiary shall not be a guarantor or obligor under a Primary Credit Agreement or any note purchase agreement of the Company from time to time (“Note Purchase
Agreement” together with the Primary Credit Agreement, the “Material Agreements”), and (iii) (A) if such Subsidiary Guarantor is a guarantor or is otherwise liable for or in respect of any Material Agreement, then such
Subsidiary Guarantor has been released and discharged (or will be released and discharged concurrently with the release of such Subsidiary Guarantor under its Subsidiary Guaranty) under the Material Agreements, (B) at the time of, and after
giving effect to, such release and discharge, no Default or Event of Default shall be existing, (C) no amount is then due and payable under such Subsidiary Guaranty and (D) if in connection with such Subsidiary Guarantor being released and
discharged under any Material Agreement any fee or other form of consideration is given to any holder of Debt under such Material Agreement for such release, the holders of the Notes shall receive equivalent consideration substantially concurrently
therewith. In the event of any such release, for purposes of Section 10.6, all Debt of such Subsidiary shall be deemed to have been incurred concurrently with such release.

 Reference is made to the Note Purchase Agreement dated

the Purchasers, together with their successors, assigns or any other future holder of the Notes (as defined below), from time to time party thereto, the “Holders”). Capitalized terms used herein and not defined herein shall have the
meanings assigned to such terms in the Note Purchase Agreement. 
 The Purchasers have agreed to purchase from the Company (i)

Subsidiary Guarantors acknowledges that it will derive substantial benefit from the sale of the Notes to the Purchasers. The obligations of the Purchasers to purchase the Notes are conditioned on, among other things, the execution and delivery by
the Subsidiary Guarantors of this Subsidiary Guarantee Agreement. In order to induce the Purchasers to purchase the Notes, the Subsidiary Guarantors are willing to execute this Agreement. 

Accordingly, the parties hereto agree as follows: 

SECTION 1. GUARANTEE. 

Each Subsidiary Guarantor unconditionally guarantees, jointly with the other Subsidiary Guarantors and severally, as a primary obligor and not
merely as a surety, the due and punctual payment of (a) the principal of and Make-Whole Amount, if any, and other premium, if any, and interest (including interest accruing during the pendency of any
bankruptcy, insolvency, receivership or other similar proceeding, regardless of whether allowed or allowable in such proceeding) on the Notes issued by the Company, when and as due, whether at maturity, by acceleration, upon one or more dates set
for prepayment or otherwise, and (b) each payment required to be made by the Company under the terms of the Notes and the Note Purchase Agreement, and (c) all other monetary obligations, including fees, costs, expenses and indemnities,
whether primary, secondary, direct, contingent, fixed or otherwise (including monetary obligations incurred during the pendency of any bankruptcy, insolvency, receivership or other similar proceeding, regardless of whether allowed or allowable in
such proceeding), of the Company and the Subsidiary Guarantors under the Note Purchase Agreement, Notes and this Agreement (the obligations referred to in the preceding clauses (a), (b), and (c) being collectively called the
“Obligations”). Each Subsidiary Guarantor agrees that the Obligations may be extended or renewed, in whole or in part, without notice to or further assent from it, and that it will remain bound upon its guarantee notwithstanding any
extension or renewal of any Obligation. 
 Each Subsidiary Guarantor further agrees that the due and punctual payment of such Obligations
may be extended or renewed, in whole or in part, without notice to or further assent from it, and that it will remain bound upon its guarantee hereunder notwithstanding any such extension or renewal of any such Obligation. 

  
 I-C-2 













 Each Subsidiary Guarantor waives presentment to, demand of payment from and protest to the
Company of any of the Obligations, and also waives notice of acceptance of its obligations and notice of protest for nonpayment. The obligations of the Subsidiary Guarantors hereunder shall not be affected by (a) the failure of any Holder to
assert any claim or demand or to enforce any right or remedy against the Company or any Subsidiary Guarantor under the provisions of the Note Purchase Agreement, the Notes, this Agreement or otherwise; (b) any extension or renewal of any of the
Obligations; (c) any rescission, waiver, amendment or modification of, or release from, any of the terms or provisions of the Note Purchase Agreement, the Notes, this Agreement or any other agreement; (d) any default, failure or delay,
willful or otherwise, in the performance of any of the Obligations; or (e) any other act, omission or delay to do any other act which may or might in any manner or to any extent vary the risk of any Subsidiary Guarantor or otherwise operate as
a discharge of a guarantor as a matter of law or equity or which would impair or eliminate any right of any Subsidiary Guarantor to subrogation. 

Each Subsidiary Guarantor further agrees that its agreement hereunder constitutes a guarantee of payment when due (whether or not any
bankruptcy or similar proceeding shall have stayed the accrual or collection of any of the Obligations or operated as a discharge thereof) and not merely of collection, and waives any right to require that any resort be had by any Holder to any
balance of any deposit account or credit on the books of any Holder in favor of the Company or any other Person. 
 The obligations of the
Subsidiary Guarantors hereunder shall not be subject to any reduction, limitation, impairment or termination for any reason, including any claim of waiver, release, surrender, alteration or compromise of any of the Obligations, and shall not be
subject to any defense or setoff, counterclaim, recoupment or termination whatsoever, by reason of the invalidity, illegality or unenforceability of any of the Obligations (including lack of due authorization or execution of the Note Purchase
Agreement, the Notes, this Agreement or any other instrument or agreement), any impossibility in the performance of any of the Obligations or otherwise. Without limiting the generality of the foregoing, the obligations of each Subsidiary Guarantor
hereunder shall not be discharged or impaired or otherwise affected by the failure of any Holder to assert any claim or demand or to enforce any remedy under the Note Purchase Agreement or any other instrument or agreement, by any waiver or
modification of any provision of any thereof, by any default, failure or delay, willful or otherwise, in the performance of the Obligations, or by any other act or omission that may or might in any manner or to any extent vary the risk of any
Subsidiary Guarantor or that would otherwise operate as a discharge of each Subsidiary Guarantor as a matter of law or equity (other than the payment in full in cash of all the Obligations). 

Each Subsidiary Guarantor further agrees that its obligations hereunder shall continue to be effective or be reinstated, as the case may be,
if at any time payment, or any part thereof, of any Obligation is rescinded or must otherwise be restored by any Holder upon the bankruptcy or reorganization of the Company or otherwise. 

In furtherance of the foregoing and not in limitation of any other right which any Holder may have at law or in equity against any Subsidiary
Guarantor by virtue hereof, upon the failure of the Company to pay any Obligation when and as the same shall become due, whether at maturity, by acceleration, after notice of prepayment or otherwise, each Subsidiary Guarantor hereby promises to and
will, upon receipt of written demand by any Holder, forthwith pay, or cause to be paid, to the applicable Holders in cash an amount equal to the unpaid principal amount of such Obligations then due, together with accrued and unpaid interest thereon.
Each Subsidiary Guarantor further agrees that if payment in respect of any Obligation shall be due in a currency other than U.S. Dollars and/or at a place of payment other than New York and if, by reason of any change in law, disruption of
currency or foreign exchange markets, war or civil disturbance or other event, payment of such Obligation in such currency or at such place of payment shall be impossible or, in the reasonable judgment of any Holder, not consistent with the
protection of its rights or interests, then, at the election of the Required Holders, such Subsidiary Guarantor shall make payment of such Obligation in U.S. Dollars (based upon the applicable exchange rate in effect on the date of payment) and/or
in New York, and shall indemnify each Holder against any losses or reasonable out-of-pocket expenses that it shall sustain as a result of such alternative payment.


  
 I-C-3 













 Upon payment by any Subsidiary Guarantor of any sums as provided above, all rights of such
Subsidiary Guarantor against the Company arising as a result thereof by way of right of subrogation or otherwise shall in all respects be subordinated and junior in right of payment to the prior indefeasible payment in full of all the Obligations
owed by the Company to the Holders. 
 Nothing shall discharge or satisfy the liability of any Subsidiary Guarantor hereunder except the
full performance and payment of the Obligations. 
 SECTION 2. DEFENSES OF THE
COMPANY WAIVED. 
 To the fullest extent permitted by applicable law, each of the Subsidiary Guarantors waives
any defense based on or arising out of any defense of the Company or any other Subsidiary Guarantor or the unenforceability of the Obligations or any part thereof from any cause, or the cessation from any cause of the liability of the Company or any
other Subsidiary Guarantor, other than the final payment in full in cash of the Obligations. The Holders may, at their election, foreclose on any security held by one or more of them by one or more judicial or nonjudicial sales, accept an assignment
of any such security in lieu of foreclosure, compromise or adjust any part of the Obligations, make any other accommodation with the Company, any Subsidiary Guarantor or any other guarantor or exercise any other right or remedy available to them
against the Company, any Subsidiary Guarantor or any other guarantor, without affecting or impairing in any way the liability of any Subsidiary Guarantor hereunder except to the extent the Obligations have been fully, finally and indefeasibly paid
in cash. Pursuant to applicable law, each of the Subsidiary Guarantors waives any defense arising out of any such election even though such election operates, pursuant to applicable law, to impair or to extinguish any right of reimbursement or
subrogation or other right or remedy of such Subsidiary Guarantor against the Company or any other Subsidiary Guarantor or guarantor, as the case may be, or any security. 

SECTION 3. SUBORDINATION. 

Upon payment by any Subsidiary Guarantor of any sums as provided herein, all rights of such Subsidiary Guarantor against the Company arising as
a result thereof by way of indemnity, contribution or subrogation or otherwise shall be fully subordinated to the indefeasible payment in full in cash of the Obligations. The subordination effected by this Section 3 shall prohibit (i) any
exercise of a set-off in respect of the subordinated obligations, (ii) the commencement of any action seeking to enforce the subordinated obligations and (iii) the assignment of subordinated
obligations. Any Subsidiary Guarantor receiving any payment in respect of a subordinated obligation in violation of this Section 3 shall be deemed to have received such payment in trust for the benefit of the Holders and immediately turn over
such amount to the Holders for application in respect of the Obligations. 

  
 I-C-4 













 SECTION 4. INFORMATION. 

Each of the Subsidiary Guarantors assumes all responsibility for being and keeping itself informed of the Company’s and the other
Subsidiary Guarantors’ financial condition and assets, and of all other circumstances bearing upon the risk of nonpayment of the Obligations and the nature, scope and extent of the risks that such Subsidiary Guarantor assumes and incurs
hereunder, and agrees that none of the Holders will have any duty to advise any of the Subsidiary Guarantors of information known to it or any of them regarding such circumstances or risks. 

SECTION 5. REPRESENTATIONS AND WARRANTIES; AGREEMENTS. 

Each Subsidiary Guarantor represents and warrants to each Holder that: 

(a) Such Subsidiary Guarantor is a corporation or other legal entity duly organized, validly existing and in good standing under the laws of
its jurisdiction of organization, and is duly qualified as a foreign corporation or 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 Subsidiary Guarantor to perform its obligations under this Agreement, or (3) the validity or enforceability of this Agreement. Such Subsidiary 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 Agreement and to perform the provisions hereof. 

(b) This Agreement has been duly authorized by all necessary action on the part of such Subsidiary Guarantor, and this Agreement constitutes a
legal, valid and binding obligation of such Subsidiary Guarantor enforceable against such Subsidiary 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 Subsidiary Guarantor of this Agreement 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 Subsidiary Guarantor or any of its subsidiaries under any indenture, mortgage, deed of trust, loan, purchase or credit agreement, lease,
charter document or by-law, or any other agreement or instrument to which such Subsidiary Guarantor or any of its subsidiaries is bound or by which such Subsidiary Guarantor or any of its subsidiaries or any
of their respective 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 Subsidiary Guarantor or any of its subsidiaries or (3) violate any provision of any statute or other rule or regulation of any Governmental Authority applicable to the such Subsidiary Guarantor or any of its
subsidiaries. 
 (d) No consent, approval or authorization of, or registration, filing or declaration with, any Governmental Authority is
required in connection with the execution, delivery or performance by such Subsidiary Guarantor of this Agreement. 

  
 I-C-5 













 (e) Without in any way limiting the generality of the warranties and representations
contained in Section 5 of the Note Purchase Agreement, each of such warranties and representations is, insofar as it refers to any Subsidiary, true and correct with respect to the Subsidiary Guarantor. 

Each Subsidiary Guarantor will comply with each of the provisions of Section 9 and Section 10 of the Note Purchase Agreement, and
each other covenant and agreement contained therein, that is applicable to any Subsidiary generally. 
 SECTION 6.
TERMINATION. 
 The guarantees made hereunder (a) shall, subject to clause (b) below, terminate when all the
Obligations have been indefeasibly paid in full in cash and (b) shall continue to be effective or be reinstated, as the case may be, if at any time payment, or any part thereof, of any Obligation is rescinded or must otherwise be restored by
any Holder or any Subsidiary Guarantor upon the bankruptcy or reorganization of the Company, any Subsidiary Guarantor or otherwise. The guarantee hereunder of any Subsidiary Guarantor shall be automatically released if all the capital stock of such
Subsidiary Guarantor owned by the Company or any Subsidiary shall be sold in a transaction not prohibited by the terms of the Note Purchase Agreement. 

SECTION 7. LIMITATION OF LIABILITY. 

Each Subsidiary Guarantor hereby confirms that it is the intention of such Subsidiary Guarantor that the guarantee by such Subsidiary Guarantor
pursuant to this Agreement not constitute a fraudulent transfer or conveyance for purposes of Title 11 of the United States Code, the Uniform Fraudulent Conveyance Act, the Uniform Fraudulent Transfer Act or any similar applicable Federal or state
law (all such statutes and laws are collectively referred to as “Fraudulent Conveyance Laws”). To effectuate the foregoing intention, each Subsidiary Guarantor hereby irrevocably agrees that the obligations of such Subsidiary
Guarantor under this Agreement shall be limited to the amount as will, after giving effect to all rights to receive any collections from or payments by or on behalf of any other Subsidiary Guarantor in respect of the obligations of such other
Subsidiary Guarantor pursuant to Section 7 hereof, result in the obligations of such Subsidiary Guarantor under this Agreement not constituting such a fraudulent transfer or conveyance. In the event that the liability of any Subsidiary
Guarantor hereunder is limited pursuant to this Section 7 to an amount that is less than the total amount of the Obligations, then it is understood and agreed that the portion of the Obligations for which such Subsidiary Guarantor is liable
hereunder shall be the last portion of the Obligations to be repaid. 
 SECTION 8. BINDING AGREEMENT;
ASSIGNMENTS. 
 Whenever in this Agreement any of the parties hereto is referred to, such reference shall be deemed to include
the successors and assigns of such party; and all covenants, promises and agreements by or on behalf of the Subsidiary Guarantors that are contained in this Agreement shall bind and inure to the benefit of each party hereto and their respective
successors and assigns. This Agreement shall become effective as to any Subsidiary Guarantor when a counterpart hereof executed on behalf of such Subsidiary Guarantor shall have been delivered to the Holders and thereafter shall be binding upon such
Subsidiary Guarantor and its successors and assigns, and shall inure to the benefit of the Holders, and their respective successors and assigns, except that no Subsidiary Guarantor shall have the right to assign its rights or obligations hereunder
or any interest herein, and any such attempted assignment shall be void. This Agreement shall be construed as a separate agreement with respect to each Subsidiary Guarantor and may be amended, modified, supplemented, waived or released with respect
to any Subsidiary Guarantor without the approval of any other Subsidiary Guarantor and without affecting the obligations of any other Subsidiary Guarantor hereunder. 

  
 I-C-6 













 SECTION 9. WAIVERS; AMENDMENT. 

(a) No failure or delay of any Holder in exercising any power or light hereunder shall operate as a waiver thereof, nor shall any single or
partial exercise of any such right or power, or any abandonment or discontinuance of steps to enforce such a right or power, preclude any other or further exercise thereof or the exercise of any other right or power. The rights and remedies of any
Holder hereunder or under the Note Purchase Agreement, the Notes or this Agreement are cumulative and are not exclusive of any rights or remedies that they would otherwise have. No waiver of any provision of this Agreement or consent to any
departure by any Subsidiary Guarantor therefrom shall in any event be effective unless the same shall be permitted by paragraph (b) below, and then such waiver or consent shall be effective only in the specific instance and for the purpose for
which given. No notice or demand on any Subsidiary Guarantor in any case shall entitle such Subsidiary Guarantor to any other or further notice or demand in similar or other circumstances. 

(b) Neither this Agreement nor any provision hereof may be waived, amended or modified except pursuant to a written agreement entered into
between the Subsidiary Guarantors to which such waiver, amendment or modification relates and the Required Holders. 
 SECTION 10.
GOVERNING LAW. 
 THIS AGREEMENT SHALL BE
GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE
OF NEW YORK. 
 SECTION 11. NOTICES. 

All communications and notices hereunder shall be in writing and given as provided in Section 18 of the Note Purchase Agreement. All
communications and notices hereunder to each Subsidiary Guarantor shall be given to it in care of the Company. 
 SECTION 12.
SURVIVAL OF AGREEMENT; SEVERABILITY. 
 (a) All covenants, agreements,
representations and warranties made by the Subsidiary Guarantors herein and in the certificates or other instruments prepared or delivered in connection with or pursuant to this Agreement shall be considered to have been relied upon by the
Purchasers and shall survive the purchasing of the Notes by the Purchasers, regardless of any investigation made by any of them or on their behalf, and shall continue in full force and effect as long as the principal of or any accrued interest on
any Note or any other fee or amount payable under the Note Purchase Agreement, the Notes or this Agreement is outstanding and unpaid. 
 (b)
In the event any one or more of the provisions contained in this Agreement should be held invalid, illegal or unenforceable in any respect, the validity, legality and enforceability of the remaining provisions contained herein shall not in any way
be affected or impaired thereby (it being understood that the invalidity of a particular provision in a particular jurisdiction shall not in and of itself affect the validity of such provision in any other jurisdiction). The parties shall endeavor
in good-faith negotiations to replace the invalid, illegal or unenforceable provisions with valid provisions the economic effect of which comes as close as possible to that of the invalid, illegal or
unenforceable provisions. 

  
 I-C-7 













 SECTION 13. COUNTERPARTS. 

This Agreement may be executed in counterparts, each of which shall constitute an original, but all of which when taken together shall
constitute a single contract, and shall become effective as provided in Section 8. Delivery of an executed signature page to this Agreement by facsimile transmission shall be as effective as delivery of a manually executed counterpart of this
Agreement. 
 SECTION 14. JURISDICTION; CONSENT TO SERVICE OF
PROCESS. 
 (a) Each Subsidiary Guarantor hereby irrevocably and unconditionally submits, for itself and its property, to the
nonexclusive jurisdiction of any New York State Court or Federal Court of the United States of America sitting in New York City, and any appellate court from any thereof, in any action or proceeding arising out of or relating to this
Agreement, or for recognition or enforcement of any judgment, and each of the parties hereto hereby irrevocably and unconditionally agrees that all claims in respect of any such action or proceeding may be heard and determined in such New York
State or, to the extent permitted by law, in such Federal court. Each of the parties hereto agrees that a final judgment in any such action or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in
any other manner provided by law. Nothing in this Agreement shall affect any right that any Holder may otherwise have to bring any action or proceeding relating to this Agreement against any Subsidiary Guarantor or its properties in the courts of
any jurisdiction. 
 (b) Each Subsidiary Guarantor hereby irrevocably and unconditionally waives, to the fullest extent it may legally and
effectively do so, any objection that it may now or hereafter have to the laying of venue of any suit, action or proceeding arising out of or relating to this Agreement in any New York State or Federal court. Each of the parties hereto hereby
irrevocably waives, to the fullest extent permitted by law, the defense of an inconvenient forum to the maintenance of such action or proceeding in any such court. 

(c) Each party to this Agreement irrevocably consents to service of process in the manner provided for notices in Section 11. Nothing in
this Agreement will affect the right of any party to this Agreement to serve process in any other manner permitted by law. 

SECTION 15. WAIVER OF JURY TRIAL. 

EACH PARTY HERETO HEREBY WAIVES, TO
THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE
TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION DIRECTLY OR
INDIRECTLY ARISING OUT OF, UNDER OR IN CONNECTION WITH THIS AGREEMENT.
EACH PARTY HERETO (A) CERTIFIES THAT NO REPRESENTATIVE, AGENT OR ATTORNEY
OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH
OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE
THE FOREGOING WAIVER AND (B) ACKNOWLEDGES THAT IT AND THE OTHER
PARTIES HERETO HAVE BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY,
AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION. 

  
 I-C-8 













 SECTION 16. ADDITIONAL SUBSIDIARY
GUARANTORS. 
 Pursuant to Section 9.5 of the Note Purchase Agreement, certain additional Subsidiaries may be required
under the terms of the Note Purchase Agreement from time to time to enter into this Agreement as Subsidiary Guarantors. Upon execution and delivery by a Subsidiary of an instrument in the form of Annex I, such Subsidiary shall become a Subsidiary
Guarantor hereunder with the same force and effect as if originally named as a Subsidiary Guarantor herein. The execution and delivery of such instrument shall not require the consent of any Subsidiary Guarantor hereunder. The rights and obligations
of each Subsidiary Guarantor hereunder shall remain in full force and effect notwithstanding the addition of any new Subsidiary Guarantor as a party to this Agreement. 

SECTION 17. RIGHT OF SETOFF. 

If an Event of Default shall have occurred and be continuing, each of the Holders is hereby authorized at any time and from time to time, to
the fullest extent permitted by law, to set off and apply any and all deposits (general or special, time or demand, provisional or final) at any time held and other Debt at any time owing by such Person to or for the credit or the account of any
Subsidiary Guarantor against any or all the obligations of such Subsidiary Guarantor now or hereafter existing under this Agreement held by such Person, irrespective of whether or not such Person shall have made any demand under this Agreement and
although such obligations may be unmatured. The rights of each Person under this Section are in addition to other rights and remedies (including other rights of setoff) which such Person may have. 

SECTION 18. CONVERSION OF CURRENCIES. 

(a) If, for the purpose of obtaining judgment in any court, it is necessary to convert a sum owing hereunder in one currency into another
currency, each party hereto agrees, to the fullest extent that it may effectively do so, that the rate of exchange used shall be that at which in accordance with normal banking procedures in the relevant jurisdiction the first currency could be
purchased with such other currency on the Business Day immediately preceding the day on which final judgment is given. 
 (b) The obligations
of each Subsidiary Guarantor in respect of any sum due to any party hereto or any holder of the obligations owing hereunder (the “Applicable Holder”) shall, notwithstanding any judgment in a currency (the “Judgment
Currency”) other than the currency in which such sum is stated to be due hereunder (the “Agreement Currency”), be discharged only to the extent that, on the Business Day following receipt by the Applicable Holder of any sum
adjudged to be so due in the Judgment Currency, the Applicable Holder may in accordance with normal banking procedures in the relevant jurisdiction purchase the Agreement Currency with the Judgment Currency; if the amount of the Agreement Currency
so purchased is less than the sum originally due to the Applicable Holder in the Agreement Currency, such Subsidiary Guarantor agrees, as a separate obligation and notwithstanding any such judgment, to indemnify the Applicable Holder against such
loss. The obligations of the Subsidiary Guarantors contained in this Section 18 shall survive the termination of this Agreement and the payment of all other amounts owing hereunder.

A. Reference is made to the Note Purchase Agreement dated March 2, 2021 (as amended, supplemented or otherwise modified from time to
time, the “Note Purchase Agreement”), among the Company and the Purchasers named on Schedule A thereto (the “Purchasers”); the Purchasers, together with their successors, assigns or any other future holder of the

 C.
The Subsidiary Guarantors have entered into the Subsidiary Guarantee Agreement in order to induce the Purchasers to purchase the Notes. The undersigned Subsidiary of the Company (the “New Subsidiary Guarantor”) is executing this

Section 3. This Supplement may be executed in counterparts, each of which shall constitute an original, but all of

unenforceable provisions. 
 Section 7. All communications and notices hereunder shall be in writing and given as
