therein or necessary in order to make the statements therein not misleading; on the date of any filing pursuant to Rule 424(b) and

on the Closing Date, the Final Prospectus (together with any supplement thereto) will not include any untrue statement of a material

fact or omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which

Company makes no representations or warranties as to (i) that part of the Registration Statement which shall constitute the Statement

in or omitted from the Registration Statement, the Final Prospectus (or any supplement thereto) or the Canadian Offering Memorandum in

(c)            At

the Execution Time, the Disclosure Package, when taken together as a whole, does not contain any untrue statement of a material fact

and in conformity with written information furnished to the Company by any Underwriter through the Representatives specifically for use

therein, it being understood and agreed that the only such information furnished by or on behalf of any Underwriter consists of the information

described as such in Section 7 hereof.

3

(d)            At

the earliest time after the filing of the Registration Statement that the Company or another offering participant made a bona fide offer

(within the meaning of Rule 164(h)(2)) of the Securities, the Company was not and is not an Ineligible Issuer (as defined in Rule 405),

without taking account of any determination by the Commission pursuant to Rule 405 that it is not necessary that the Company be

considered an Ineligible Issuer.

(e)            Each

Issuer Free Writing Prospectus and the final term sheet prepared and filed pursuant to Section 4(A)(g) hereto do not include

any information that conflicts with the information contained in the Registration Statement, including any document incorporated therein

and any prospectus supplement deemed to be a part thereof that has not been superseded or modified. The foregoing sentence does not apply

to statements in or omissions from the Disclosure Package based upon and in conformity with written information furnished to the Company

by any Underwriter through the Representatives specifically for use therein, it being understood and agreed that the only such information

furnished by or on behalf of any Underwriter consists of the information described as such in Section 7 hereof.

(f)            (i) At

the time of filing the Registration Statement, (ii) at the time of the most recent amendment thereto for the purposes of complying

with Section 10(a)(3) of the Act (whether such amendment was by post-effective amendment, incorporated report filed pursuant

to Sections 13 or 15(d) of the Exchange Act or form of prospectus), and (iii) at the time the Company or any person acting

on its behalf (within the meaning, for this clause only, of Rule 163(c)) made any offer relating to the Securities in reliance on

the exemption in Rule 163, the Company was or is (as the case may be) a “well-known seasoned issuer” as defined in Rule 405.

The Company agrees to pay the fees required by the Commission relating to the Securities within the time required by Rule 456(b)(1) without

regard to the proviso therein and otherwise in accordance with Rules 456(b) and 457(r).

2.            Purchase

and Sale. Subject to the terms and conditions and in reliance upon the representations and warranties herein set forth, the Company

agrees to sell to each Underwriter, and each Underwriter agrees, severally and not jointly, to purchase from the Company, at the purchase

price set forth in Schedule I hereto, the respective principal amounts of the Securities set forth opposite each respective Underwriter’s

name in Schedule II hereto, except that, if Schedule I hereto provides for the sale of Securities pursuant to delayed delivery arrangements,

the respective principal amounts of Securities to be purchased by the Underwriters shall be as set forth in Schedule II hereto, less

the respective amounts of Contract Securities determined as provided below. Securities to be purchased by the Underwriters are herein

sometimes called the “Underwriters’ Securities” and Securities to be purchased pursuant to Delayed Delivery Contracts

as hereinafter provided are herein called “Contract Securities”.

4

If so provided in Schedule I hereto, the Underwriters

are authorized to solicit offers to purchase Securities from the Company pursuant to delayed delivery contracts (“Delayed Delivery

Contracts”), substantially in the form of Schedule IV hereto but with such changes therein as the Company may authorize or approve.

The Underwriters will endeavor to make such arrangements and, as compensation therefor, the Company will pay to the Representatives,

for the account of underwriters, on the Closing Date, the percentage set forth in Schedule I hereto of the principal amount of the Securities

for which Delayed Delivery Contracts are made. Delayed Delivery Contracts are to be with institutional investors, including commercial

and savings banks, insurance companies, pension funds, investment companies and educational and charitable institutions. The Company

will make Delayed Delivery Contracts in all cases where sales of Contract Securities arranged by the Underwriters have been approved

by the Company but, except as the Company may otherwise agree, each such Delayed Delivery Contract must be for not less than the minimum

principal amount set forth in Schedule I hereto and the aggregate principal amount of Contract Securities may not exceed the maximum

aggregate principal amount set forth in Schedule I hereto. The Underwriters will not have any responsibility in respect of the validity

or performance of Delayed Delivery Contracts. The principal amount of Securities to be purchased by each Underwriter as set forth in

Schedule II hereto shall be reduced by an amount which shall bear the same proportion to the total principal amount of Contract Securities

as the principal amount of Securities set forth opposite the name of such Underwriter bears to the aggregate principal amount set forth

in Schedule II hereto, except to the extent that you determine that such reduction shall be otherwise than in such proportion and so

advise the Company in writing; provided, however, that the total principal amount of Securities to be purchased by all

Underwriters shall be the aggregate principal amount set forth in Schedule II hereto, less the aggregate principal amount of Contract

Securities.

It is understood and agreed that the offering

of the Securities in Canada by the Underwriters as contemplated herein shall be made in the provinces of Canada on a private placement

basis in accordance with applicable exemptions from the prospectus requirements of applicable Canadian Securities Laws.

3.             Delivery

and Payment. Delivery of and payment for the Underwriters’ Securities shall be made at the office, on the date and at the time

specified in Schedule I hereto, which date and time may be postponed by agreement between the Representatives and the Company or as provided

in Section 8 hereof (such date and time of delivery and payment for the Securities being called the “Closing Date”).

Delivery of the Underwriters’ Securities shall be made to the Representatives for the respective accounts of the several Underwriters

against payment by the several Underwriters through the Representatives of the purchase price thereof to or upon the order of the Company

by certified or official bank check or checks payable, or wire transfers, in immediately available funds. The Securities will be issued

in the form of one or more definitive global Securities in book-entry form in the name of CDS & Co., as nominee of CDS Clearing

and Depository Services Inc. (“CDS”). Delivery of the Securities shall be made through the facilities of CDS unless the Company

and the Representatives shall otherwise agree. The Underwriters shall cause their Canadian counsel to deposit the certificates representing

the Securities with CDS.

4.             Agreements.

(A)           The

Company agrees with the several Underwriters that:

(a)            The

Company will file the Final Prospectus, properly completed, pursuant to the applicable paragraph of Rule 424(b) within the

time period prescribed and will provide evidence satisfactory to the Representatives of such timely filing. The Company will promptly

advise the Representatives (i) when any amendment to the Registration Statement relating to the Securities shall have become effective,

(ii) of any request by the Commission for any amendment of the Registration Statement or amendment of or supplement to the Final

Prospectus or for any additional information, (iii) of any request by any securities regulatory authority in any province of Canada

(collectively, the “Canadian Securities Authorities”) for any amendment to the Canadian Offering Memorandum or for

any additional information, (iv) of the issuance by the Commission or Canadian Securities Authorities of any stop order suspending

the effectiveness of the Registration Statement or the Canadian Offering Memorandum or of any notice that would prevent their use or

the institution or threatening of any proceeding for that purpose and (v) of the receipt by the Company of any notification with

respect to the suspension of the qualification of the Securities for sale in any jurisdiction or the initiation or threatening of any

proceeding for such purpose. The Company will use its best efforts to prevent the issuance of any such stop order and, if issued, to

obtain as soon as possible the withdrawal thereof. The Company will not file any amendment of the Registration Statement or supplement

to the Final Prospectus unless the Company has furnished you a copy for your review prior to filing and will not file any such proposed

amendment or supplement to which you reasonably object.

5

(b)            If,

at any time when a prospectus relating to the Securities is required to be delivered under the Act (including in circumstances where

such requirement may be satisfied pursuant to Rule 172) or the Canadian Offering Memorandum is required to be delivered under applicable

Canadian Securities Laws, any event occurs as a result of which the Final Prospectus or Canadian Offering Memorandum as then amended

or supplemented would include any untrue statement of a material fact or omit to state any material fact necessary to make the statements

therein in the light of the circumstances under which they were made not misleading or contain a “misrepresentation” as defined

under the applicable Canadian Securities Laws, as applicable, or if it shall be necessary to amend or supplement the Final Prospectus

or Canadian Offering Memorandum to comply with the Act, the Exchange Act, the respective rules thereunder or the applicable Canadian

Securities Laws, the Company will give the Representatives immediate notice of the occurrence of such event and promptly will prepare

and file with the Commission, subject to the first sentence of paragraph (a) of this Section 4, an amendment or supplement

which will correct such statement or omission or an amendment which will effect such compliance.

(c)            The

Company will make generally available to its security holders and to the Representatives as soon as practicable, but not later than 45

days after the end of the 12-month period beginning at the end of the current fiscal quarter of the Company, an earning statement (which

need not be audited) of the Company and its subsidiaries, covering a period of at least 12 months beginning after the end of the current

fiscal quarter of the Company, which will satisfy the provisions of Section 11(a) of the Act and Rule 158 thereunder.

(d)            The

Company will furnish to the Representatives and counsel for the Underwriters, without charge, copies of the Registration Statement (including

exhibits thereto) and each amendment thereto which shall become effective on or prior to the Closing Date and, so long as delivery of

a prospectus by an Underwriter or dealer may be required by the Act (including in circumstances where such requirement may be satisfied

pursuant to Rule 172), as many copies of any Preliminary Final Prospectus, the Final Prospectus, any Preliminary Canadian Offering

Memorandum, the Canadian Offering Memorandum and each Issuer Free Writing Prospectus and any amendments thereof and supplements thereto

as the Representatives may reasonably request.

6

(e)            The

Company will arrange for the qualification of the Securities for sale under the laws of such jurisdictions as the Representatives may

designate, will maintain such qualifications in effect so long as required for the distribution of the Securities and will arrange for

the determination of the legality of the Securities for purchase by institutional investors.

(f)            Until

the earlier of the day on which the distribution of the Securities is completed or the business day following the Closing Date, the Company

will not, without the consent of the Representatives, offer or sell, or announce the offering of, any Canadian dollar denominated debt

securities covered by the Registration Statement or any other registration statement filed under the Act.

(g)            The

Company will prepare a final term sheet, containing solely a description of the Securities, in a form approved by you, and will file

such term sheet pursuant to Rule 433(d) within the time required by such Rule.

(h)            If

there occurs an event or development as a result of which the Disclosure Package would include an untrue statement of a material fact

or would omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances then prevailing,

not misleading or contain a “misrepresentation” as defined under applicable Canadian Securities Laws, the Company will notify

promptly the Representatives so that any use of the Disclosure Package may cease until it is amended or supplemented.

(i)            The

Company agrees that, unless it obtains the prior written consent of the Representatives, it has not made and will not make any offer

relating to the Securities that would constitute an Issuer Free Writing Prospectus or that would otherwise constitute a “free writing

prospectus” (as defined in Rule 405) required to be filed by the Company with the Commission or retained by the Company under

Rule 433, other than the final term sheet prepared and filed pursuant to Section 4(A)(g) hereto; provided that the prior

written consent of the parties hereto shall be deemed to have been given in respect of the Free Writing Prospectuses included in Schedule

III hereto. Any such free writing prospectus consented to by the Representatives is hereinafter referred to as a “Permitted Free

Writing Prospectus.” The Company agrees that (x) it has treated and will treat, as the case may be, each Permitted Free Writing

Prospectus as an Issuer Free Writing Prospectus and (y) it has complied and will comply, as the case may be, with the requirements

of Rules 164 and 433 applicable to any Permitted Free Writing Prospectus, including in respect of timely filing with the Commission,

legending and record keeping.

(j)            The

Company will cause to be provided or filed all documents required to be provided to or filed with the applicable Canadian Securities

Authorities in connection with the offering of Securities in the provinces of Canada in accordance with applicable Canadian Securities

Laws, including, without limitation, any offering memorandum (under applicable Canadian Securities Laws) and, subject to the compliance

by each Underwriter with its obligations under Section 4(B)(o) hereof, any reports of trade on Form 45-106F1 – Report

of Exempt Distribution (“Form 45-106F1”) prescribed by National Instrument 45-106 – Prospectus Exemptions

(“NI 45-106”), as applicable.

7

(k)            The

Company will use its commercially reasonable efforts to cause the eligibility of the Securities for clearance and settlement through

the facilities of CDS.

(l)             The

Company will pay all fees and expenses of the Company in connection with the approval of the Securities by CDS (as defined herein) for

“book-entry” transfer, all fees payable in connection with the filing of any Form 45-106F1 with applicable Canadian

securities regulatory authorities and any levy or fees payable to the Canadian Investment Regulatory Organization.

(B)            Each

Underwriter agrees severally with the Company that:

(a)            The

Representatives will pay the expenses of printing and distributing all documents relating to the offering.

(b)            The

Representatives will pay the reasonable fees and disbursements of outside counsel for the Company and the Underwriters relating to the

offering.

(c)            The

Representatives will pay any fees of Moody’s Investors Service, Inc. (“Moody’s”), Fitch Ratings Inc. (“Fitch”)

and S&P Global Ratings, a division of S&P Global Inc. (“S&P”) relating to the rating of the Securities.

(d)            The

Representatives will pay the fees and disbursements of PricewaterhouseCoopers LLP relating to the preparation of the letter required

by Section 5(e) of this Agreement.

Representatives will pay the reasonable fees and expenses of The Bank of New York Mellon, as Trustee.

(f)            The

Representatives will pay any and all fees associated with listing the Securities on any United States or foreign securities exchange.

(g)            The

Representatives will pay any and all travel expenses incurred by the Company in connection with the offering of the Securities.

(h)            The

Representatives will pay any and all other miscellaneous expenses and/or taxes associated with the offering.

(i)            Such

Underwriter will furnish the Company with a copy of each proposed Free Writing Prospectus to be prepared by or on behalf of such Underwriter

before its first use and not to use any Free Writing Prospectus, to which the Company reasonably objects, provided, however, that without

consent of the Company each Underwriter may use the final term sheet prepared and filed pursuant to Section 4(A)(g) hereto

and one or more preliminary term sheets relating to the Securities containing customary information.

8

(j)            The

sale and delivery of any Security to any purchaser located or resident in Canada (each, a “Canadian Purchaser”) by such Underwriter

will be made only in accordance with the condition that such Canadian Purchaser: (i) is an “accredited investor” as

defined in Section 73.3 of the Securities Act (Ontario) or in Section 1.1 of NI 45-106 purchasing or deemed to be purchasing

the Security as principal; (ii) is not a person created or being used solely to purchase or hold securities as an accredited investor

as described in paragraph (m) of the definition of “accredited investor” in section 1.1 of NI 45-106; and (iii) is

a “permitted client” as defined in National Instrument 31-103 – Registration Requirements, Exemptions and Ongoing

and will obtain, as necessary, and retain relevant information and documentation to evidence the steps taken to verify compliance with

the AI Requirements in accordance with its usual document retention policies and procedures in compliance with applicable laws, and will

provide to the Company forthwith upon written request all such information or documentation as the Company may reasonably request in

good faith and solely for the purpose of verifying compliance with the AI Requirements;

(k)            Such

Underwriter has not provided and will not provide any Canadian Purchaser any document or other material that would constitute an “offering

memorandum” within the meaning of Canadian Securities Laws (other than the Preliminary Canadian Offering Memorandum and the Canadian

Offering Memorandum) with respect to the private placement of the Securities in Canada;

(l)            Such

Underwriter, except as disclosed in the Canadian Offering Memorandum, is not a person or company in respect of which the Company is a

“connected issuer” or a “related issuer” within the respective meanings of those terms in National Instrument

33-105 – Underwriting Conflicts of the Canadian Securities Administrators;

(m)            Such

Underwriter is duly registered as an “investment dealer” or “exempt market dealer” as defined under Canadian

Securities Laws or is otherwise exempt from the dealer registration requirements of Canadian Securities Laws in the applicable Canadian

provinces in connection with the offer and sale of the Securities to Canadian Purchasers;

(n)            Such

Underwriter will comply in all material respects with all relevant Canadian Securities Laws in distributing the Securities; and

(o)            Such

Underwriter will, as soon as available and in any event within three (3) business days following the Closing Date, provide to the

Company the information pertaining to each such Canadian Purchaser of the Securities as required to be disclosed in Schedule I of Form 45-106F1

under NI 45-106, which Form 45-106F1 is required to be filed by the Company under NI 45-106 with the Canadian Securities Authorities

in the provinces of Canada in which each such Canadian Purchaser resides.

to the Obligations of the Underwriters. The obligations of the Underwriters to purchase the Underwriters’ Securities shall

be subject to the accuracy of the representations and warranties on the part of the Company contained herein as of the Execution Time,

as of the date of the effectiveness of any amendment to the Registration Statement filed prior to the Closing Date (including the filing

of any document incorporated by reference therein) and as of the Closing Date, to the accuracy of the statements of the Company made

in any certificates pursuant to the provisions hereof, to the performance by the Company of its obligations hereunder and to the following

filings by Rule 433; and no stop order suspending the effectiveness of the Registration Statement, as amended from time to time,

or any notice that would prevent its use shall have been issued and no proceedings for that purpose shall have been instituted or threatened.

(b)            The

Company shall have furnished to the Representatives:

(i)            the

opinion of the General Counsel, an Assistant General Counsel, an Associate General Counsel or other senior counsel of the Company, dated

the Closing Date, to the effect that:

(A)            the

Company has been duly incorporated and is validly existing as a corporation in good standing under the laws of the State of New York,

with full corporate power and authority to own its properties and conduct its business as described in the Disclosure Package, the Final

Prospectus and the Canadian Offering Memorandum, and is duly qualified to do business as a foreign corporation and is in good standing

under the laws of each jurisdiction within the United States which requires such qualifications wherein it owns or leases material properties

or conducts material business;

(B)            the

Securities conform in all material respects to the description thereof contained in the Disclosure Package, Final Prospectus and Canadian

Offering Memorandum;

(C)            the

Indenture has been duly authorized, executed and delivered, has been duly qualified under the Trust Indenture Act, and constitutes a

legal, valid and binding obligation enforceable against the Company in accordance with its terms (subject to applicable bankruptcy, insolvency,

fraudulent transfer, reorganization, moratorium and other similar laws affecting creditors’ rights generally from time to time

in effect, and subject, as to enforceability, to general principles of equity, regardless of whether such enforceability is considered

in a proceeding in equity or at law); and the Securities have been duly authorized and, when executed and authenticated in accordance

with the provisions of the Indenture and delivered to and paid for by the Underwriters pursuant to this Agreement, in the case of the

Underwriters’ Securities, or by the purchasers thereof pursuant to Delayed Delivery Contracts, in the case of any Contract Securities,

will constitute legal, valid and binding obligations of the Company entitled to the benefits of the Indenture (subject to applicable

bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium, and other similar laws affecting creditors’ rights generally

from time to time in effect);

10

(D)            to

the best knowledge of such counsel, there is no pending or threatened action, suit or proceeding before any court or governmental agency,

authority or body or any arbitrator involving the Company or any of its subsidiaries, of a character required to be disclosed in the

Registration Statement which is not adequately disclosed in the Disclosure Package, the Final Prospectus and the Canadian Offering Memorandum,

and there is no franchise, contract or other document of a character required to be described in the Registration Statement, Final Prospectus

or Canadian Offering Memorandum, or to be filed as an exhibit, which is not described or filed as required;

(E)            the

Registration Statement and any amendments thereto have become effective under the Act; any required filing of the Basic Prospectus, any

Preliminary Final Prospectus and the Final Prospectus, and any supplements thereto, pursuant to Rule 424(b) has been made in

the manner and within the time period required by Rule 424(b); to the best knowledge of such counsel, no stop order suspending the

effectiveness of the Registration Statement, as amended, or any notice that would prevent its use, has been issued, and no proceedings

for that purpose have been instituted or are pending or contemplated under the Act;

(F)            this

Agreement and any Delayed Delivery Contracts have been duly authorized, executed and delivered by the Company;

(G)            no

authorization, approval or other action by, and no notice to, consent of, order of, or filing with, any United States Federal or New

York governmental authority or regulatory body is required for the consummation of the transactions contemplated herein or in any Delayed

Delivery Contracts, except such as have been obtained under the Act and such as may be required under the blue sky laws of any jurisdiction

in connection with the purchase and distribution of the Securities and such other approvals (specified in such opinion) as have been

obtained;

(H)            such

counsel has no reason to believe that (1) the Registration Statement and the Final Prospectus (except the financial statements and

the notes thereto and other information of an accounting or financial nature included therein, and the Statement of Eligibility (Form T-1)

included as an exhibit to the Registration Statement, as to which such counsel need express no view) were not appropriately responsive

in all material respects to requirements of the Act and the applicable rules and regulations of the Commission thereunder or (2) the

Registration Statement or any amendment thereof at the time it became effective or at the Execution Time contained any untrue statement

of a material fact or omitted to state any material fact required to be stated therein or necessary to make the statements therein not

misleading or that neither the Final Prospectus nor the Canadian Offering Memorandum, as amended or supplemented, either as of their

respective date or the Closing Date contains or contained any untrue statement of a material fact or omits or omitted to state a material

fact necessary to make the statements therein, in light of the circumstances under which they were made, not misleading (in each case

except for the financial statements and the notes thereto and other information of an accounting or financial nature included therein,

as to which such counsel need express no view);

11

(I)              none

of the issue and sale of the Securities, the consummation of any other of the transactions herein contemplated or the fulfillment of

the terms hereof or of any Delayed Delivery Contracts will conflict with, result in a breach of, or constitute a default under, the charter

or by-laws of the Company or the terms of any indenture or other agreement or instrument known to such counsel and to which the Company

or any of its subsidiaries is a party or bound, or any decree or regulation known to such counsel to be applicable to the Company or

any of its subsidiaries of any court, regulatory body, administrative agency, governmental body or arbitrator having jurisdiction over

the Company or any of its subsidiaries; and

(J)             such

counsel has no reason to believe that the Disclosure Package, at the Execution Time, contained any untrue statement of a material fact

or omitted to state any material fact necessary in order to make the statements therein, in the light of circumstances under which they

were made, not misleading.

The statements described in one or more

of paragraphs (B), (C), (E), (F), (G), (H) and (J) of this subsection 5(b)(i) may be omitted from the opinion of such

counsel; provided, however, that in such event the Company shall also have furnished to the Representatives the corresponding opinion

or letter of Allen Overy Shearman Sterling US LLP, counsel for the Company, described in subsection 5(b)(ii) or 5(b)(iii) immediately

following.

(ii)            in

the event that the statements described in one or more of paragraphs (B), (C), (E), (F) or (G) of foregoing subsection 5(b)(i) is

omitted from the opinion delivered pursuant to such subsection, the opinion of Allen Overy Shearman Sterling US LLP, counsel for the

Company, dated the Closing Date, to the effect of the statements so omitted.

In rendering such opinions, such counsel

may rely (A) as to matters involving the application of laws of any jurisdiction other than the State of New York, the general corporation

law of the State of Delaware or the United States, to the extent they deem proper and specified in such opinion, upon the opinion of

other counsel of good standing whom they believe to be reliable and who are satisfactory to counsel for the Underwriters; and (B) as

to matters of fact, to the extent they deem proper, on certificates of responsible officers of the Company and public officials.

12

(iii)            in

the event that the statements in paragraph (H) or (J) of subsection 5(b)(i) are omitted from the opinion provided pursuant

to such subsection, a letter of Allen Overy Shearman Sterling US LLP dated the Closing Date to the effect that, having participated in

conferences with certain officers of, and with the accountants for, the Company and having made certain inquiries and investigations

in connection with the preparation of the Registration Statement, the Disclosure Package and the Final Prospectus, such counsel has no

reason to believe that (i) the Registration Statement and the Final Prospectus (except the financial statements and the notes thereto

and other information of an accounting or financial nature included therein, and the Statement of Eligibility (Form T-1) included

as an exhibit to the Registration Statement, as to which such counsel need express no view) were not appropriately responsive in all

material respects with requirements of the Act and the applicable rules and regulations of the Commission thereunder or (ii) the

Registration Statement at the Effective Date or the Execution Time contained an untrue statement of a material fact or omitted to state

a material fact required to be stated therein or necessary to make the statements therein not misleading, the Disclosure Package at the

Execution Time contained any untrue statement of a material fact or omitted to state a material fact necessary to make the statements

therein, in light of the circumstances under which they were made, not misleading, or the Final Prospectus, either as of its date or

on the Closing Date, includes any untrue statement of a material fact or omits to state a material fact necessary in order to make the

statements therein, in light of the circumstances under which they were made, not misleading (in each case except for the financial statements

and the notes thereto and other information of an accounting or financial nature included therein, as to which such counsel need express

no view).

(c)            The

Representatives shall have received from Davis Polk & Wardwell LLP, counsel for the Underwriters, such opinion or opinions,

dated the Closing Date, with respect to the issuance and sale of the Securities, the Indenture, any Delayed Delivery Contracts, the Registration

Statement, the Final Prospectus, Disclosure Package and other related matters as the Representatives may reasonably require, and the

Company shall have furnished to such counsel such documents as they request for the purpose of enabling them to pass upon such matters.

(d)            The

Representatives shall have received from Osler, Hoskin & Harcourt LLP, Canadian counsel for the Company, such opinion or opinions,

dated the Closing Date with respect to such matters as the Representatives shall reasonably request.

(e)            The

Representatives shall have received from McCarthy Tétrault LLP, Canadian counsel for the Underwriters, such opinion or opinions,

dated the Closing Date with respect to such matters as the Representatives shall reasonably request.

(f)            The

Company shall have furnished to the Representatives a certificate of the Company, signed by the principal financial or accounting officer

(or Vice President and Treasurer) of the Company, dated the Closing Date, to the effect that the signer of such certificate has carefully

examined the Registration Statement, the Disclosure Package, the Final Prospectus and any supplements or amendments thereto and this

Agreement and that:

(i)            the

representations and warranties of the Company in this Agreement are true and correct in all material respects on and as of the Closing

Date with the same effect as if made on the Closing Date and the Company has complied with all the agreements and satisfied all the conditions

on its part to be performed or satisfied at or prior to the Closing Date;

13

(ii)            no

stop order suspending the effectiveness of the Registration Statement, as amended, or any notice that would prevent its use has been

issued and no proceedings for that purpose have been instituted or, to the Company’s knowledge, threatened;

(iii)            since

the date of the most recent financial statements included or incorporated in the Disclosure Package or the Final Prospectus, there has

been no material adverse change in the condition (financial or other), earnings, business or properties of the Company and its subsidiaries,

whether or not arising from transactions in the ordinary course of business, except as set forth in or contemplated in the Disclosure

Package and the Final Prospectus; and

(iv)            no

order, ruling or decision of any Canadian federal or provincial court or Canadian Securities Authority restricting or ceasing trading

in all of the securities of the Company or suspending or preventing the use of the Preliminary Canadian Offering Memorandum or the Canadian

Offering Memorandum has been issued and no notification from any Canadian federal or provincial court or Canadian Securities Authority

of the institution or threatening of any proceeding for such purpose has been received.

(g)            At

the Closing Date, PricewaterhouseCoopers LLP shall have furnished to the Representatives a letter or letters with respect to the consolidated

financial statements and certain financial information of the Company (which may refer to a letter previously delivered to one or more

of the Representatives), dated as of the Closing Date, in form and substance satisfactory to the Representatives, confirming that they

are independent accountants within the meaning of the Act and the Exchange Act and the respective applicable published rules and

regulations thereunder, that the response, if any, to Item 10 of the Registration Statement is correct insofar as it relates to them

and stating in effect that:

(i)            in

their opinion the audited financial statements and schedules thereto included or incorporated in the Registration Statement, the Disclosure

Package, the Final Prospectus and the Canadian Offering Memorandum and reported on by them comply as to form in all material respects

with the applicable accounting requirements of the Exchange Act and the published rules and regulations thereunder with respect

to financial statements and financial statement schedules included or incorporated in annual reports on Form 10-K under the Exchange

Act;

(ii)            on

the basis of a reading of the unaudited financial statements included or incorporated in the Registration Statement, the Disclosure Package,

the Final Prospectus and the Canadian Offering Memorandum and of the latest unaudited financial statements made available by the Company

and its subsidiaries; carrying out certain specified procedures (but not an examination in accordance with generally accepted auditing

standards) which would not necessarily reveal matters of significance with respect to the comments set forth in such letter; a reading

of the minutes of the meetings of the stockholders, directors and executive committees of the Company and the subsidiaries since the

date of the latest audited balance sheet, through a specified date not more than five business days prior to the date of the letter;

and inquiries of certain officials of the Company who have responsibility for financial and accounting matters of the Company and its

subsidiaries as to transactions and events subsequent to the date of the most recent financial statements incorporated in the Registration

Statement, the Final Prospectus and the Canadian Offering Memorandum, nothing came to their attention which caused them to believe that:

14

(1)            any

unaudited financial statements included or incorporated in the Registration Statement, the Disclosure Package, the Final Prospectus and

the Canadian Offering Memorandum do not comply as to form in all material respects with applicable accounting requirements, and with

the published rules and regulations of the Commission with respect to financial statements included or incorporated in quarterly

reports on Form 10-Q under the Exchange Act; and said unaudited financial statements are not stated on a basis substantially consistent

with that of the audited financial statements included or incorporated in the Registration Statement, the Final Prospectus and the Canadian

Offering Memorandum;

(2)            with

respect to the period subsequent to the date of the most recent financial statements incorporated in the Registration Statement, the

Disclosure Package, the Final Prospectus and the Canadian Offering Memorandum, there were, at a specified date not more than five business

days prior to the date of the letter, any increases in long-term debt of the Company and its subsidiaries or decreases in the capital

stock of the Company or decreases in the stockholders’ equity of the Company and its subsidiaries as compared with the amounts

shown on the most recent consolidated balance sheet included or incorporated in the Registration Statement, the Disclosure Package, the

Final Prospectus and the Canadian Offering Memorandum, except in all instances for increases or decreases set forth in such letter, in

which case the letter shall be accompanied by an explanation by the Company as to the significance thereof unless said explanation is

not deemed necessary by the Representatives; and

(iii)           they

have performed certain other procedures as a result of which they determined that the information described in a schedule to be delivered

on behalf of the Underwriters of an accounting, financial or statistical nature (which is limited to accounting, financial or statistical

information derived from the general ledger of the Company) set forth in the Registration Statement, as amended, the Disclosure Package,

the Final Prospectus, as amended or supplemented, the Canadian Offering Memorandum and in Exhibit 12 to the Registration Statement

(including selected accounting, financial or statistical information included or incorporated in the Company’s Annual Report on

Form 10-K incorporated in the Final Prospectus or any of the Company’s Quarterly Reports on Form 10-Q incorporated therein),

agrees with the general ledger of the Company and its subsidiaries, excluding any questions of legal interpretation.

References to the Final Prospectus

in this paragraph (e) include any supplements thereto at the date of the letter.

(h)            Subsequent

to the respective dates of which information is given in the Registration Statement, the Disclosure Package, the Final Prospectus and

the Canadian Offering Memorandum, there shall not have been (i) any change or decrease specified in the letter or letters referred

to in paragraph (e) of this Section 5 or (ii) any change, or any development involving a prospective change, in or affecting

the business or properties of the Company and its subsidiaries the effect of which, in any case referred to in clause (i) or (ii) above,

is, in the judgment of the Representatives, so material and adverse as to make it impractical or inadvisable to proceed with the public

offering or the delivery of the Securities as contemplated by the Registration Statement, the Disclosure Package, the Final Prospectus

and the Canadian Offering Memorandum.

15

(i)            Prior

to the Closing Date, the Company shall have furnished to the Representatives such further information, certificates and documents as

the Representatives may reasonably request.

(j)            The

Company shall have accepted Delayed Delivery Contracts in any case where sales of Contract Securities arranged by the Underwriters have

been approved by the Company.

(k)            Subsequent

to the Execution Time, there shall not have been any decrease in the ratings of any of the Securities by Moody’s, Fitch or S&P

and neither Moody’s nor Fitch nor S&P shall have publicly announced that it has placed any of the Securities on a credit watch

with negative implications.

(l)            The

Securities shall be eligible for clearance and settlement through the facilities of CDS.

If any of the conditions specified in this Section 5

shall not have been fulfilled in all material respects when and as provided in this Agreement, or if any of the opinions and certificates

mentioned above or elsewhere in this Agreement shall not be in all material respects reasonably satisfactory in form and substance to

the Representatives and their counsel, this Agreement and all obligations of the Underwriters hereunder may be canceled at, or at any

time prior to, the Closing Date by the Representatives. Notice of such cancelation shall be given to the Company in writing or by telephone

confirmed in writing.

6.             Reimbursement

of Underwriters’ Expenses. If the sale of the Securities provided for herein is not consummated because any condition to the

obligations of the Underwriters set forth in Section 5 hereof is not satisfied or because of any refusal, inability or failure on

the part of the Company to perform any agreement herein or comply with any provision hereof other than by reason of a default by any

of the Underwriters, the Company will reimburse the Underwriters severally upon demand for all out-of-pocket expenses (including reasonable

fees and disbursements of counsel) that shall have been incurred by them in connection with the proposed purchase and sale of the Securities.

7.             Indemnification

and Contribution.

(a)            The

Company agrees to indemnify and hold harmless each Underwriter and each person who controls any Underwriter within the meaning of either

the Act or the Exchange Act against any and all losses, claims, damages or liabilities, joint or several, to which they or any of them

may become subject under the Act, the Exchange Act or other Federal or state statutory law or regulation, at common law or otherwise,

insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement

or alleged untrue statement of a material fact contained in the Registration Statement for the registration of the Securities as originally

filed or in any amendment thereof, or in the Basic Prospectus, any Preliminary Final Prospectus, any Preliminary Canadian Offering Memorandum,

the Final Prospectus, the Canadian Offering Memorandum or any Issuer Free Writing Prospectus, or in any amendment thereof or supplement

thereto, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein

or necessary to make the statements therein not misleading, or a “misrepresentation” as defined under the applicable Canadian

Securities Laws, as applicable, and agrees to reimburse each such indemnified party for any legal or other expenses reasonably incurred,

as incurred, by them in connection with investigating or defending any such loss, claim, damage, liability or action; provided,

however, that the Company will not be liable in any such case to the extent that any such loss, claim, damage or liability arises

out of or is based upon any such untrue statement or alleged untrue statement or omission or alleged omission made therein in reliance

upon and in conformity with written information furnished to the Company by or on behalf of any Underwriter through the Representatives

specifically for use in connection with the preparation thereof. This indemnity agreement will be in addition to any liability which

the Company may otherwise have.

16

(b)            Each

Underwriter severally agrees to indemnify and hold harmless the Company, each of its directors, each of its officers who signs the Registration

Statement, and each person who controls the Company within the meaning of either the Act or the Exchange Act, to the same extent as the

foregoing indemnity from the Company to each Underwriter, but only with reference to written information relating to such Underwriter

furnished to the Company by or on behalf of such Underwriter through the Representatives specifically for use in the preparation of the

documents referred to in the foregoing indemnity. This indemnity agreement will be in addition to any liability which any Underwriter

may otherwise have. The Company acknowledges that the statements set forth in the last paragraph of the cover page of the Final

Prospectus (including as incorporated in the Canadian Offering Memorandum) and under the heading “Underwriting” or “Plan

of Distribution” and, if Schedule I hereto provides for sales of Securities pursuant to delayed delivery arrangements, in the last

sentence under the heading “Delayed Delivery Arrangements” in any Preliminary Final Prospectus or the Final Prospectus (including

as incorporated in any Preliminary Canadian Offering Memorandum or the Canadian Offering Memorandum, as applicable), constitute the only

information furnished in writing by or on behalf of the several Underwriters for inclusion in the Basic Prospectus, any Preliminary Final

Prospectus, any Preliminary Canadian Offering Memorandum, the Final Prospectus, the Canadian Offering Memorandum or any Issuer Free Writing

Prospectus, and you, as the Representatives, confirm that such statements are correct.

(c)            Promptly

after receipt by an indemnified party under this Section 7 of notice of the commencement of any action, such indemnified party will,

if a claim in respect thereof is to be made against the indemnifying party under this Section 7, notify the indemnifying party in

writing of the commencement thereof; but the omission so to notify the indemnifying party will not relieve it from any liability which

it may have to any indemnified party otherwise than under this Section 7. In case any such action is brought against any indemnified

party, and it notifies the indemnifying party of the commencement thereof, the indemnifying party will be entitled to appoint counsel

satisfactory to such indemnified party to represent the indemnified party in such action; provided, however, if the defendants

in any such action include both the indemnified party and the indemnifying party and the indemnified party shall have reasonably concluded

that there may be legal defenses available to it and/or other indemnified parties which are different from or additional to those available

to the indemnifying party, the indemnified party or parties shall have the right to select separate counsel to defend such action on

behalf of such indemnified party or parties. Upon receipt of notice from the indemnifying party to such indemnified party of its election

so to appoint counsel to defend such action and approval by the indemnified party of counsel, the indemnifying party will not be liable

to such indemnified party under this Section 7 for any legal or other expenses subsequently incurred by such indemnified party in

connection with the defense thereof unless (i) the indemnified party shall have employed separate counsel in accordance with the

proviso to the next preceding sentence (it being understood, however, that the indemnifying party shall not be liable for the expenses

of more than one separate counsel (in addition to any local counsel), approved by the Representatives in the case of paragraph (b) of

this Section 7, representing the indemnified parties under such paragraph (b) who are parties to such action), (ii) the

indemnifying party shall not have employed counsel reasonably satisfactory to the indemnified party to represent the indemnified party

within a reasonable time after notice of commencement of the action or (iii) the indemnifying party has authorized the employment

of counsel for the indemnified party at the expense of the indemnifying party; and except that, if clause (i) or (iii) is applicable,

such liability shall be only in respect of the counsel referred to in such clause (i) or (iii).

17

(d)            In

order to provide for just and equitable contribution in circumstances in which the indemnification provided for in paragraph (b) of

this Section 7 is due in accordance with its terms but is for any reason held by a court to be unavailable from the Company on grounds

of policy or otherwise, the Company and the Underwriters shall contribute to the aggregate losses, claims, damages and liabilities (including

legal or other expenses reasonably incurred in connection with investigating or defending same) to which the Company and one or more

of the Underwriters may be subject in such proportion so that the Underwriters are responsible for that portion represented by the percentage

that the underwriting discount bears to the sum of such discount and the purchase price of the Securities set forth on Schedule I hereto

and the Company is responsible for the balance; provided, however, that (y) in no case shall any Underwriter (except

as may be provided in any agreement among underwriters relating to the offering of the Securities) be responsible for any amount in excess

of the underwriting discount applicable to the Securities purchased by such Underwriter hereunder and (z) no person guilty of fraudulent

misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was

not guilty of such fraudulent misrepresentation. For purposes of this Section 7, each person who controls an Underwriter within

the meaning of either the Act or the Exchange Act shall have the same rights to contribution as such Underwriter, and each person who

controls the Company within the meaning of either the Act or the Exchange Act, each officer of the Company who shall have signed the

Registration Statement and each director of the Company shall have the same rights to contribution as the Company, subject in each case

to clauses (y) and (z) of this paragraph (d). Any party entitled to contribution will, promptly after receipt of notice of

commencement of any action, suit or proceeding against such party in respect of which a claim for contribution may be made against another

party or parties under this paragraph (d), notify such party or parties from whom contribution may be sought, but the omission to so

notify such party or parties shall not relieve the party or parties from whom contribution may be sought from any other obligation it

or they may have hereunder or otherwise than under this paragraph (d).

8.            Default

by an Underwriter. If any one or more Underwriters shall fail to purchase and pay for any of the Securities agreed to be purchased

by such Underwriter or Underwriters hereunder and such failure to purchase shall constitute a default in the performance of its or their

obligations under this Agreement, the remaining Underwriters shall be obligated severally to take up and pay for (in the respective proportions

which the amount of Securities set forth opposite their names in Schedule II hereto bears to the aggregate amount of Securities set forth

opposite the names of all the remaining Underwriters) the Securities which the defaulting Underwriter or Underwriters agreed but failed

to purchase; provided, however, that in the event that the aggregate amount of Securities which the defaulting Underwriter

or Underwriters agreed but failed to purchase shall exceed 10% of the aggregate amount of Securities set forth in Schedule II hereto,

the remaining Underwriters shall have the right to purchase all, but shall not be under any obligation to purchase any, of the Securities,

and if such nondefaulting Underwriters do not purchase all the Securities, this Agreement will terminate without liability to any nondefaulting

Underwriter or the Company. In the event of a default by any Underwriter as set forth in this Section 8, the Closing Date shall

be postponed for such period, not exceeding seven days, as the Representatives shall determine in order that the required changes in

the Registration Statement, the Disclosure Package, the Final Prospectus, the Canadian Offering Memorandum or in any other documents

or arrangements may be effected. Nothing contained in this Agreement shall relieve any defaulting Underwriter of its liability, if any,

to the Company and any nondefaulting Underwriter for damages occasioned by its default hereunder.

18

9.            Recognition

of the U.S. Special Resolution Regimes.

(a)            In

the event that any Underwriter that is a Covered Entity becomes subject to a proceeding under a U.S. Special Resolution Regime, the transfer

from such Underwriter of this Agreement, and any interest and obligation in or under this Agreement, will be effective to the same extent

as the transfer would be effective under the U.S. Special Resolution Regime if this Agreement, and any such interest and obligation,

were governed by the laws of the United States or a state of the United States.

(b)            In

the event that any Underwriter that is a Covered Entity or a BHC Act Affiliate of such Underwriter becomes subject to a proceeding under

a U.S. Special Resolution Regime, Default Rights under this Agreement that may be exercised against such Underwriter are permitted to

be exercised to no greater extent than such Default Rights could be exercised under the U.S. Special Resolution Regime if this Agreement

were governed by the laws of the United States or a state of the United States.

(c)            For

purposes of this Section 9:

“BHC Act Affiliate” has

the meaning assigned to the term “affiliate” in, and shall be interpreted in accordance with, 12 U.S.C. § 1841(k).

“Covered Entity” means

any of the following:

(i)            a

“covered entity” as that term is defined in, and interpreted in accordance with, 12 C.F.R. § 252.82(b);

(ii)           a

“covered bank” as that term is defined in, and interpreted in accordance with, 12 C.F.R. § 47.3(b); or

(iii)          a

“covered FSI” as that term is defined in, and interpreted in accordance with, 12 C.F.R. § 382.2(b).

19

“Default Right” has the

meaning assigned to that term in, and shall be interpreted in accordance with, 12 C.F.R. §§ 252.81, 47.2 or 382.1, as applicable.

“U.S. Special Resolution Regime”

means each of (i) the Federal Deposit Insurance Act and the regulations promulgated thereunder and (ii) Title II of the Dodd-Frank

Wall Street Reform and Consumer Protection Act and the regulations promulgated thereunder.

10.            Termination.

This Agreement shall be subject to termination in the absolute discretion of the Representatives, by notice given to the Company prior

to delivery of and payment for the Securities, if prior to such time (i) trading in securities generally on the New York Stock Exchange

shall have been suspended or limited or minimum prices shall have been established on such Exchange, (ii) a banking moratorium shall

have been declared either by Federal, New York State or Canadian authorities or (iii) there shall have occurred any outbreak or

material escalation of hostilities or other calamity or crisis the effect of which on the financial markets of the United States or Canada

is such as to make it, in the judgment of the Representatives, impracticable to market the Securities.

11.            Representations

and Indemnities to Survive. The respective agreements, representations, warranties, indemnities and other statements of the Company

or its officers and of the Underwriters set forth in or made pursuant to this Agreement will remain in full force and effect, regardless

of any investigation made by or on behalf of any Underwriter or the Company or any of the officers, directors or controlling persons

referred to in Section 7 hereof, and will survive delivery of and payment for the Securities. The provisions of Sections 6 and 7

hereof shall survive the termination or cancelation of this Agreement.

12.            Notices.

All communications hereunder will be in writing and effective only on receipt, and, if sent to the Representatives, will be mailed at

the address specified in Schedule I hereto; or, if sent to the Company, will be mailed at 1 New Orchard Road, Armonk, New York 10504;

attention of the Treasurer.

13.            Successors.

This Agreement will inure to the benefit of and be binding upon the parties hereto and their respective successors and the officers and

directors and controlling persons referred to in Section 7 hereof, and no other person will have any right or obligation hereunder.

14.           Applicable

Law. This Agreement will be governed by and construed in accordance with the laws of the State of New York.

20

15.            Arms-Length

Transaction. The Company acknowledges and agrees that (i) the purchase and sale of the Securities pursuant to this Agreement

is an arm’s-length commercial transaction between the Company, on the one hand, and the several Underwriters, on the other, (ii) in

connection therewith and with the process leading to such transaction each Underwriter is acting solely as a principal and not the agent

or fiduciary of the Company, (iii) no Underwriter has assumed an advisory of fiduciary responsibility in favor of the Company with

respect to the offering contemplated hereby or the process leading thereto (irrespective of whether such Underwriter has advised or is

currently advising the Company on other matters) or any other obligation to the Company except the obligations expressly set forth in

this Agreement and (iv) the Company has consulted its own legal and financial advisors to the extent it deemed appropriate. The

Company agrees that it will not claim that the Underwriters, or any of them, has rendered advisory services of any nature or respect,

or owes a fiduciary or similar duty to the Company, in connection with such transaction or the process leading thereto.

16.            Submission

to Jurisdiction. Each party hereto hereby irrevocably submits to the jurisdiction of any New York State court sitting in the Borough

of Manhattan in the City of New York or any federal court sitting in the Borough of Manhattan in the City of New York in respect of any

suit, action or proceeding arising out of or relating to this Agreement, the Basic Prospectus, the Final Prospectus, the Canadian Offering

Memorandum or the offering of the Securities, and irrevocably accepts for itself and in respect of its property, generally and unconditionally,

jurisdiction of the aforesaid courts. To the extent that the Company has or hereafter may acquire any immunity (on the grounds of sovereignty

or otherwise) from the jurisdiction of any court or from any legal process with respect to itself or its property, the Company irrevocably

waives, to the fullest extent permitted by law, such immunity in respect of any such suit, action or proceeding.

17.           Waiver

of Jury Trial.      The Company and each of the Underwriters

hereby irrevocably waives, to the fullest extent permitted by applicable law, any and all right to trial by jury in any legal proceeding

arising out of or relating to this Agreement or the transactions contemplated hereby.

Items specified pursuant to Section 5(g)(iii) to

Other Terms:

1.            Section 4(B)(a) -

(h) are deleted.

2.            Each

of the Underwriters severally agrees that it will not offer, sell, or deliver any of the Securities, directly or indirectly, or distribute

the prospectus supplement or prospectus or any other offering material relating to the Securities, in or from any jurisdiction except

under circumstances that will, to the best of such Underwriter’s knowledge and belief, result in compliance with the applicable

laws and regulations and which will not impose any obligations on the Company.

Each of the Underwriters

also severally agrees to abide by the following offering restrictions:

Prohibition of Sales to

European Economic Area (“EEA”) Retail Investors

Each Underwriter represents

and agrees that it has not offered, sold, distributed or otherwise made available and will not offer, sell, distribute or otherwise make

available any Securities to any retail investor in the EEA. For the purposes of this provision:

(a)            the

expression “retail investor” means a person who is one (or more) of the following:

(i)            a

retail client as defined in point (11) of Article 4(1) of Directive 2014/65/EU (as amended, “MiFID II”);

I-2

(ii)            a

customer within the meaning of Directive (EU) 2016/97 (as amended, the “Insurance Distribution Directive”), where that customer

would not qualify as a professional client as defined in point (10) of Article 4(1) of MiFID II; or

(iii)            not

a qualified investor as defined in Regulation (EU) 2017/1129, as amended; and

(b)            the

expression “an offer” includes the communication in any form and by any means of sufficient information on the terms of the

offer and the Securities to be offered so as to enable an investor to decide to purchase or subscribe for the Securities.

Consequently, no key information

document required by Regulation (EU) No 1286/2014 (as amended, the “PRIIPs Regulation”) for offering, distributing or selling

the Securities or otherwise making them available to retail investors in the EEA has been prepared, and therefore offering, distributing

or selling the Securities or otherwise making them available to any retail investor in the EEA may be unlawful under the PRIIPs Regulation.

Prohibition of Sales to

United Kingdom (“U.K.”) Retail Investors

Each Underwriter represents

and agrees that it has not offered, sold, distributed or otherwise made available and will not offer, sell, distribute or otherwise make

available any Securities to any retail investor in the U.K. For the purposes of this provision:

(a)            the

expression “retail investor” means a person who is either one or both of the following:

(i)            not

a professional client, as defined in point (8) of Article 2(1) of Regulation (EU) No. 600/2014 as it forms part of

domestic law by virtue of the European Union (Withdrawal) Act 2018 (the “EUWA”); or

(ii)            not

a qualified investor as defined in paragraph 15 of Schedule 1 to the Public Offers and Admissions to Trading Regulations 2024 (“POATRs”);

and

(b)            the

expression “offer” includes the communication in any form and by any means of sufficient information on the terms of the

offer and the Securities to be offered so as to enable an investor to decide to buy or subscribe for the Securities.

Consequently, no disclosure

document required by the FCA Product Disclosure Sourcebook (“DISC”) for offering, selling or distributing the Securities

or otherwise making them available to retail investors in the U.K. has been prepared and therefore offering, selling or distributing

the Securities or otherwise making them available to any retail investor in the U.K. may be unlawful under DISC and the Consumer Composite

Investments (Designated Activities) Regulations 2024.

I-3

Each Underwriter severally

represents and agrees that it and each of its affiliates:

(a)            has

only communicated or caused to be communicated and will only communicate or cause to be communicated an invitation or inducement to engage

in investment activity (within the meaning of Section 21 of the Financial Services and Markets Act 2000, as amended (the “FSMA”))

received by it in connection with the issue or sale of the Securities in circumstances in which Section 21(1) of the FSMA does

not apply to the Company; and

(b)            has

complied with, and will comply with, all applicable provisions of the FSMA and the Financial Services Act 2012 with respect to anything

done by it in relation to the Securities in, from or otherwise involving the U.K.

3.            The

last sentence of Section 7(b) shall be deleted and replaced by the following text:

The Company acknowledges that the statements

set forth in the last paragraph of the cover page of the Preliminary Final Prospectus, (including as incorporated in the Preliminary

Canadian Offering Memorandum) and the Final Prospectus (including as incorporated in the Canadian Offering Memorandum), the sentence

“The underwriters have informed IBM that they intend to make a market in the Notes but are under no obligation to do so and such

market making may be terminated at any time without notice.” and the statements contained in the fourth paragraph, seventh through

ninth paragraphs and the first, fourth, fifth, sixth and seventh sentences of the tenth paragraph under the caption “Underwriting”

in the Preliminary Final Prospectus (including as incorporated in the Preliminary Canadian Offering Memorandum) and the Final Prospectus

(including as incorporated in the Canadian Offering Memorandum) constitute the only information furnished in writing by or on behalf

of the several Underwriters for inclusion in the Basic Prospectus, any Preliminary Final Prospectus, any Preliminary Canadian Offering

Memorandum, the Disclosure Package, any Issuer Free Writing Prospectus, the Final Prospectus or the Canadian Offering Memorandum, and

you, as the Representatives, confirm that such statements are correct.

4.            The

following shall be an additional condition added to Section 5:

The Company shall have furnished to

the Representatives the opinion of Allen Overy Shearman Sterling US LLP, counsel to the Company, dated the Closing Date to the effect

that the statements under the caption “United States Taxation” in the Disclosure Package, the Final Prospectus and the Canadian

Offering Memorandum constitute a fair presentation of the material U.S. federal income tax consequences to holders of Securities.

5.            For

purposes of Section 8, the 2030 Notes and the 2034 Notes shall be treated as two separate series of Securities, and Section 8

shall apply to each series as if this Underwriting Agreement applied solely to such series.

6.            The

following shall be a new Section 18:

18.          Electronic

Signatures. This Agreement may be executed by any one or more of the parties hereto in any number of counterparts (which may include

counterparts delivered by any standard form of telecommunication), each of which shall be deemed to be an original, but all such respective

counterparts shall together constitute one and the same Agreement. Counterparts may be delivered via facsimile, electronic mail (including

any electronic signature covered by the U.S. federal ESIGN Act of 2000, Uniform Electronic Transactions Act, the Electronic Signatures

and Records Act or other applicable law, e.g., www.docusign.com) or other transmission method and any counterpart so delivered shall

be deemed to have been duly and validly delivered and be valid and effective for all purposes.

INTERNATIONAL BUSINESS MACHINES

CORPORATION, a corporation duly organized and existing under the laws of the State of New York (herein called the “Company”,

which term includes any successor corporation under the Indenture referred to on the reverse hereof), for value received, hereby promises

to pay to CDS & Co. or registered assigns, the principal sum as set forth in the attached Schedule of Increases or Decreases,

at the office or agency of the Company in the Borough of Manhattan, The City and State of New York, or any other office or agency designated

by the Company for that purpose, on August 15, 2030, in the coin or currency of Canada, and to pay interest, semi-annually in arrears

on February 15 and August 15 of each year, commencing February 15, 2027, on said principal sum at said office or agency,

in like coin or currency, at the rate of 4.100% per annum, from the August 15 or February 15 next preceding the date of this

Note to which interest has been paid, unless the date hereof is a date to which interest has been paid, in which case from the date of

this Note, or unless no interest has been paid on the Notes (as defined on the reverse hereof), in which case from August 17, 2026,

until payment of said principal sum has been made or duly provided for. Notwithstanding the foregoing, if the date hereof is after the

record date and before the immediately following August 15 or February 15 interest payment date, this Note shall bear interest

from such August 15 or February 15 immediately following interest payment date; provided, however, that if the Company shall

default in the payment of interest due on such August 15 or February 15, then this Note shall bear interest from the next preceding

August 15 or February 15 to which interest has been paid, or, if no interest has been paid on the Notes, from August 17,

2026. The interest so payable on any August 15 or February 15 will, subject to certain exceptions provided in the Indenture

referred to on the reverse hereof, be paid to the person in whose name this Note is registered at the close of business on the preceding

February 1 or August 1 of the next applicable interest payment date (whether or not a Business Day), unless the Company shall

default in the payment of interest due on such interest payment date, in which case such defaulted interest, at the option of the Company,

may be paid to the person in whose name this Note is registered at the close of business on a special record date for the payment of

such defaulted interest established by notice to the registered holders of Notes not less than ten days preceding such special record

date or may be paid in any other lawful manner not inconsistent with the requirements of any securities exchange on which the Notes may

be listed. The Company will pay the principal of, interest on and additional amounts, if any, in respect of this Note in immediately

available funds. For a full semi-annual interest period, interest on this Note will be computed on the basis of a 360-day year consisting

of twelve 30-day months. For an interest period that is not a full semi-annual interest period, interest on the Notes will be computed

on the basis of a 365-day year and the actual number of days in such interest period (Actual/Actual Canadian Compound Method). Solely

for the purpose of disclosure under the Interest Act (Canada), the yearly rate of interest to which the rate used in such computation

is equivalent during any particular period is the rate so used (x) multiplied by the actual number of days in the calendar year

in which the period for which such interest or fee is payable (or compounded) ends, and (y) divided by the number of days based

on which such rate is calculated. Initially, Computershare Advantage Trust of Canada will act as paying agent. The Company reserves the

right at any time to vary or terminate the appointment of any paying agent, to appoint additional or other paying agents and to approve

any change in the office through which any paying agent acts. Reference is made to the further provisions of this Note set forth on the

reverse hereof. Such further provisions shall for all purposes have the same effect as though fully set forth at this place.

This Note shall not be valid

or become obligatory for any purpose until the certificate of authentication hereon shall have been signed by the Trustee under the Indenture

referred to on the reverse hereof.

Authorized Signatory

[Signature Page to CAD 2030 Note]

This security is one of a

duly authorized issue of unsecured debentures, notes or other evidences of indebtedness of the Company (hereinafter called the “Securities”),

of the series hereinafter specified, all issued or to be issued under an indenture dated as of October 1, 1993, duly executed and

delivered by the Company to The Bank of New York Mellon, a New York banking corporation, as trustee (hereinafter called the “Trustee”),

as supplemented by the First Supplemental Indenture dated as of December 15, 1995, between the Company and the Trustee, as trustee

(together, hereinafter called the “Indenture”), to which Indenture and all indentures supplemental thereto reference is hereby

made for a description of the respective rights and duties thereunder of the Trustee, the Company and the holders of the Securities.

The Securities may be issued in one or more series, which different series may be issued in various aggregate principal amounts, may

mature at different times, may bear interest at different rates, may have different conversion prices (if any), may be subject to different

redemption provisions, may be subject to different sinking, purchase or analogous funds, may be subject to different covenants and Events

of Default and may otherwise vary as in the Indenture provided. This Security is one of a series designated as the 4.100% Notes due 2030

of the Company (hereinafter called the “Notes”) issued under the Indenture.

In case an Event of Default

with respect to the Notes, as defined in the Indenture, shall have occurred and be continuing, the principal hereof together with interest

accrued thereon, if any, may be declared, and upon such declaration shall become, due and payable, in the manner, with the effect and

subject to the conditions provided in the Indenture.

The Indenture contains provisions

permitting the Company and the Trustee, with the consent of the holders of not less than a majority in aggregate principal amount of

the Securities at the time outstanding of all series to be affected (acting as one class), to execute supplemental indentures adding

any provisions to or changing in any manner or eliminating any of the provisions of the Indenture or of any supplemental indenture or

modifying in any manner the rights of the holders of the Securities of such series to be affected; provided, however, that no such supplemental

indenture shall, among other things, (i) change the fixed maturity of the principal of, or any installment of principal of or interest

on, or the currency of payment of, any Security; (ii) reduce the principal amount thereof or the rate of interest thereon or any

premium payable upon the redemption thereof; (iii) impair the right to institute suit for the enforcement of any such payment on

or after the fixed maturity thereof (or, in the case of redemption, on or after the redemption date); (iv) reduce the percentage

in principal amount of the outstanding Securities of any series, the consent of whose holders is required for any such supplemental indenture,

or the consent of whose holders is required for any waiver (of compliance with certain provisions of the Indenture or certain defaults

thereunder and their consequences) provided for in the Indenture; (v) change any obligation of the Company, with respect to outstanding

Securities of a series, to maintain an office or agency in the places and for the purposes specified in the Indenture for such series;

or (vi) modify any of the foregoing provisions or the provisions for the waiver of certain covenants and defaults, except to increase

any applicable percentage of the aggregate principal amount of outstanding Securities the consent of the holders of which is required

or to provide with respect to any particular series the right to condition the effectiveness of any supplemental indenture as to that

series on the consent of the holders of a specified percentage of the aggregate principal amount of outstanding Securities of such series

or to provide that certain other provisions of the Indenture cannot be modified or waived without the consent of the holder of each outstanding

Security affected thereby. It is also provided in the Indenture that the holders of a majority in aggregate principal amount of the Securities

of a series at the time outstanding may on behalf of the holders of all the Securities of such series waive any past default under the

Indenture with respect to such series and its consequences, except a default in the payment of the principal of, premium, if any, or

interest, if any, on any Security of such series or in respect of a covenant or provision which cannot be modified without the consent

of the Holder of each outstanding Security of the series affected. Any such consent or waiver by the holder of this Note shall be conclusive

and binding upon such holder and upon all future holders and owners of this Note and any Notes which may be issued in exchange or substitution

herefor, irrespective of whether or not any notation thereof is made upon this Note or such other Notes.

No reference herein to the

Indenture and no provision of this Note or of the Indenture shall alter or impair the obligation of the Company, which is absolute and

unconditional, to pay the principal of, if any, and interest on this Note at the place, at the respective times, at the rate and in the

coin or currency herein prescribed.

The Indenture permits the

Company to Discharge its obligations with respect to the Notes on the 91st day following the satisfaction of the conditions set forth

in the Indenture, which include the deposit with the Trustee of money or Foreign Government Securities or a combination thereof sufficient

to pay and discharge each installment of principal of (including premium, if any, on) and interest, if any, on the outstanding Notes.

If the Company shall, in

accordance with Section 901 of the Indenture, consolidate with or merge into any other corporation or convey or transfer its properties

and assets substantially as an entirety to any Person, the successor shall succeed to, and be substituted for, the Person named as the

“Company” on the face of this Note, all on the terms set forth in the Indenture.

The Notes are issuable in

registered form without coupons in denominations of C$2,000 and any integral multiple of C$1,000 in excess thereof. In the manner and

subject to the limitations provided in the Indenture, but without the payment of any service charge, Notes may be exchanged for an equal

aggregate principal amount of Notes of other authorized denominations at the office or agency of the Company maintained for such purpose

in the Borough of Manhattan, The City and State of New York, or any other office or agency designated by the Company for such purpose.

All payments of principal,

interest and additional amounts, if any, including payments made upon any redemption of the Notes, will be made in Canadian dollars.

If Canadian dollars are unavailable to the Company due to the imposition of exchange controls or other circumstances beyond the Company’s

control or if Canadian dollars are no longer used for the settlement of transactions by public institutions of or within the international

banking community, then all payments in respect of this Note will be made in U.S. dollars until Canadian dollars are again available

to the Company or so used. In such circumstances, the amount payable on any date in Canadian dollars will be converted into U.S. dollars

on the basis of the most recently available market exchange rate for the Canadian dollar. Any payment in respect of this Note so made

in U.S. dollars will not constitute an Event of Default as defined in the Indenture.

The Company will, subject

to the exceptions and limitations set forth below, pay as additional interest on this Note such additional amounts as are necessary in

order that the net payment by the Company or a paying agent of the principal of and interest on the Notes to a holder who is not a United

States person (as defined below), after deduction for any present or future tax, assessment or other governmental charge of the United

States or a political subdivision or taxing authority of or in the United States, imposed by withholding with respect to the payment,

will not be less than the amount provided in this Note to be then due and payable; provided, however, that the foregoing obligation to

pay additional amounts shall not apply:

not have been entitled to the payment of an additional amount had the beneficiary, settlor, beneficial owner or member received directly

its beneficial or distributive share of the payment;

(3)            to

any tax, assessment or other governmental charge that is imposed otherwise or withheld solely by reason of a failure of the holder or

regulation of the United States Treasury Department or by an applicable income tax treaty to which the United States is a party as a

with the implementation thereof;

(9)            with

respect to any payment to the extent such payment could have been made without such deduction or withholding if the holder or beneficial

owner of the Notes had presented the Notes for payment (where presentation is permitted or required for payment) within 30 days after

As used in this Note, the

term “United States” means the United States of America (including the states and the District of Columbia) and its territories,

possessions and other areas subject to its jurisdiction, and the term “United States person” means any individual who is

a citizen or resident of the United States, a corporation, partnership or other entity created or organized in or under the laws of the

United States, any state of the United States or the District of Columbia (other than a partnership that is not treated as a United States

person under any applicable Treasury regulations), or any estate or trust the income of which is subject to United States federal income

taxation regardless of its source.

If, as a result of any change

in, or amendment to, the laws (or any regulations or rulings promulgated under the laws) of the United States (or any political subdivision

or taxing authority of or in the United States), or any change in, or amendments to, an official position regarding the application or

interpretation of such laws, regulations or rulings, which change or amendment is announced or becomes effective on or after August 10,

2026, the Company becomes, or based upon a written opinion of independent counsel selected by the Company, will become obligated to pay

additional amounts as described above with respect to this Note, then the Company may at its option redeem, in whole, but not in part,

this Note on not less than 30 nor more than 60 days prior notice, at a redemption price equal to 100% of its principal amount, together

with interest accrued but unpaid on this Note to the date fixed for redemption.

The Notes will be redeemable,

as a whole or in part, at the Company’s option, at any time or from time to time (in C$1,000 increments, provided that any remaining

principal amount thereof shall be at least the minimum authorized denomination thereof), on at least 10 days’, but not more than

60 days’, prior notice (by mail, electronic delivery or otherwise in accordance with the procedures of CDS) to the holders of the

Notes to be redeemed (with a copy to the Trustee and the paying agent). Prior to the Par Call Date, as defined below, the redemption

price for the Notes will be equal to the greater of:

· 100%

of the principal amount of the Notes to be redeemed; and

· the

Canada Yield Price with respect to the Notes to be redeemed,

plus, in each case, accrued and unpaid interest

on the Notes to be redeemed to, but excluding, the Redemption Date.

On and after the Par Call

Date, the redemption price for the Notes will be equal to 100% of the principal amount of the Notes to be redeemed plus accrued and unpaid

interest to, but excluding, the Redemption Date.

“Business Day”

means any day other than a Saturday or Sunday that is not a day on which banking institutions in the City of New York, New York, United

States or Toronto, Ontario, Canada are authorized or required by law or executive order to close.

“Canada Yield Price”

means, in respect of any Notes being redeemed, the price, in respect of the principal amount of such Notes, calculated by the Company

as of the third Business Day prior to the Redemption Date of such Notes, equal to the sum of the present values of the Remaining Scheduled

Payments using a discount rate equal to the Government of Canada Yield on such Business Day plus 20 basis points.

“Government of Canada

Yield” means, on any date, the bid-side yield to maturity on such date as determined by the arithmetic average (rounded to three

decimal places) of the yields quoted at 10:00 a.m. (Toronto time) by any two investment dealers in Canada selected by the Company,

assuming semi-annual compounding and calculated in accordance with generally accepted financial practice, which a non-callable Government

of Canada bond would carry if issued in Canadian dollars in Canada at 100% of its principal amount on such date with a term to maturity

that most closely approximates the remaining term of the Notes to the Par Call Date.

“Par Call Date”

means July 15, 2030 (one month prior to the maturity date of the Notes).

“Remaining Scheduled

Payments” means, with respect to each Note to be redeemed, the remaining scheduled payments of the principal thereof and interest

thereon that would be due after the related Redemption Date if the Note were redeemed on the Par Call Date. If the Redemption Date is

not an interest payment date with respect to such Note, the amount of the next succeeding scheduled interest payment thereon will be

reduced by the amount of interest accrued thereon to, but excluding, the Redemption Date.

The Company will notify the

Trustee and the paying agent of the redemption price promptly after the calculation thereof and the Trustee and the paying agent shall

not be responsible or liable for any calculation of the redemption price or of any component thereof.

On and after the Redemption

Date, interest will cease to accrue on the Notes or any portion thereof called for redemption (unless we default in the payment of the

redemption price and accrued and unpaid interest). On or before the Redemption Date, we will deposit with a paying agent money sufficient

to pay the redemption price of and accrued and unpaid interest on the Notes to be redeemed on that date.

If any Note is to be redeemed

in part, such Note must be redeemed in a minimum principal amount of C$1,000 and in integral multiples of C$1,000 in principal amount

in excess thereof (provided that any remaining principal amount thereof shall be at least the minimum authorized denomination thereof).

For so long as the Notes are held by CDS, the redemption and the selection of Notes to be redeemed shall be in accordance with the policies

and procedures of CDS and its participants.

Upon due presentation for

registration of transfer of this Note at the office or agency of the Company for such registration in the Borough of Manhattan, The City

and State of New York, or any other office or agency designated by the Company for such purpose, a new Note or Notes of authorized denominations

for an equal aggregate principal amount will be issued to the transferee in exchange herefor, subject to the limitations provided in

the Indenture, without charge except for any tax or other governmental charge imposed in connection therewith.

Prior to due presentment

for registration of transfer of this Note, the Company, the Trustee and any agent of the Company or the Trustee may deem and treat the

registered holder hereof as the absolute owner of this Note (whether or not this Note shall be overdue) for the purpose of receiving

payment of the principal of, premium, if any, and interest on this Note, as herein provided, and for all other purposes, and neither

the Company nor the Trustee nor any agent of the Company or the Trustee shall be affected by any notice of the contrary. All payments

made to or upon the order of such registered holder shall, to the extent of the sum or sums paid, effectually satisfy and discharge liability

for moneys payable on this Note.

If the Company issues definitive

Notes, interest on such Notes will be payable either by check mailed to each holder or, upon application by a holder to the registrar

not later than the relevant record date, by wire transfer in immediately available funds to that holder’s account, which application

shall remain in effect until the holder notifies the registrar, in writing, to the contrary.

No recourse for the payment

Company or any successor corporation, whether by virtue of any constitution, statute or rule of law or by the enforcement of any

assessment or penalty or otherwise, all such liability being, by the acceptance hereof and as part of the consideration for the issue

hereof, expressly waived and released. Unless otherwise defined in this Note, all terms used in this Note which are defined in the Indenture

referred to on the reverse hereof, be paid to the person in whose name this Note is registered at the close of business on the preceding

February 1 or August 1 of the next applicable interest payment date (whether or not a Business Day), unless the Company shall

default in the payment of interest due on such interest payment date, in which case such defaulted interest, at the option of the Company,

may be paid to the person in whose name this Note is registered at the close of business on a special record date for the payment of

such defaulted interest established by notice to the registered holders of Notes not less than ten days preceding such special record

date or may be paid in any other lawful manner not inconsistent with the requirements of any securities exchange on which the Notes may

be listed. The Company will pay the principal of, interest on and additional amounts, if any, in respect of this Note in immediately

available funds. For a full semi-annual interest period, interest on this Note will be computed on the basis of a 360-day year consisting

of twelve 30-day months. For an interest period that is not a full semi-annual interest period, interest on the Notes will be computed

on the basis of a 365-day year and the actual number of days in such interest period (Actual/Actual Canadian Compound Method). Solely

for the purpose of disclosure under the Interest Act (Canada), the yearly rate of interest to which the rate used in such computation

is equivalent during any particular period is the rate so used (x) multiplied by the actual number of days in the calendar year

in which the period for which such interest or fee is payable (or compounded) ends, and (y) divided by the number of days based

on which such rate is calculated. Initially, Computershare Advantage Trust of Canada will act as paying agent. The Company reserves the

right at any time to vary or terminate the appointment of any paying agent, to appoint additional or other paying agents and to approve

any change in the office through which any paying agent acts. Reference is made to the further provisions of this Note set forth on the

reverse hereof. Such further provisions shall for all purposes have the same effect as though fully set forth at this place.

This Note shall not be valid

or become obligatory for any purpose until the certificate of authentication hereon shall have been signed by the Trustee under the Indenture

referred to on the reverse hereof.

IN WITNESS WHEREOF, the Company

has caused this instrument to be duly executed under its corporate seal.

THE BANK OF NEW YORK MELLON, as Trustee

By COMPUTERSHARE ADVANTAGE TRUST OF CANADA

As Authenticating Agent

by

Authorized Signatory

[Signature Page to CAD 2034 Note]

This security is one of a

duly authorized issue of unsecured debentures, notes or other evidences of indebtedness of the Company (hereinafter called the “Securities”),

of the series hereinafter specified, all issued or to be issued under an indenture dated as of October 1, 1993, duly executed and

delivered by the Company to The Bank of New York Mellon, a New York banking corporation, as trustee (hereinafter called the “Trustee”),

as supplemented by the First Supplemental Indenture dated as of December 15, 1995, between the Company and the Trustee, as trustee

(together, hereinafter called the “Indenture”), to which Indenture and all indentures supplemental thereto reference is hereby

made for a description of the respective rights and duties thereunder of the Trustee, the Company and the holders of the Securities.

The Securities may be issued in one or more series, which different series may be issued in various aggregate principal amounts, may

mature at different times, may bear interest at different rates, may have different conversion prices (if any), may be subject to different

redemption provisions, may be subject to different sinking, purchase or analogous funds, may be subject to different covenants and Events

of Default and may otherwise vary as in the Indenture provided. This Security is one of a series designated as the 4.750% Notes due 2034

of the Company (hereinafter called the “Notes”) issued under the Indenture.

In case an Event of Default

with respect to the Notes, as defined in the Indenture, shall have occurred and be continuing, the principal hereof together with interest

accrued thereon, if any, may be declared, and upon such declaration shall become, due and payable, in the manner, with the effect and

subject to the conditions provided in the Indenture.

The Indenture contains provisions

permitting the Company and the Trustee, with the consent of the holders of not less than a majority in aggregate principal amount of

the Securities at the time outstanding of all series to be affected (acting as one class), to execute supplemental indentures adding

any provisions to or changing in any manner or eliminating any of the provisions of the Indenture or of any supplemental indenture or

modifying in any manner the rights of the holders of the Securities of such series to be affected; provided, however, that no such supplemental

indenture shall, among other things, (i) change the fixed maturity of the principal of, or any installment of principal of or interest

on, or the currency of payment of, any Security; (ii) reduce the principal amount thereof or the rate of interest thereon or any

premium payable upon the redemption thereof; (iii) impair the right to institute suit for the enforcement of any such payment on

or after the fixed maturity thereof (or, in the case of redemption, on or after the redemption date); (iv) reduce the percentage

in principal amount of the outstanding Securities of any series, the consent of whose holders is required for any such supplemental indenture,

or the consent of whose holders is required for any waiver (of compliance with certain provisions of the Indenture or certain defaults

thereunder and their consequences) provided for in the Indenture; (v) change any obligation of the Company, with respect to outstanding

Securities of a series, to maintain an office or agency in the places and for the purposes specified in the Indenture for such series;

or (vi) modify any of the foregoing provisions or the provisions for the waiver of certain covenants and defaults, except to increase

any applicable percentage of the aggregate principal amount of outstanding Securities the consent of the holders of which is required

or to provide with respect to any particular series the right to condition the effectiveness of any supplemental indenture as to that

series on the consent of the holders of a specified percentage of the aggregate principal amount of outstanding Securities of such series

or to provide that certain other provisions of the Indenture cannot be modified or waived without the consent of the holder of each outstanding

Security affected thereby. It is also provided in the Indenture that the holders of a majority in aggregate principal amount of the Securities

of a series at the time outstanding may on behalf of the holders of all the Securities of such series waive any past default under the

Indenture with respect to such series and its consequences, except a default in the payment of the principal of, premium, if any, or

interest, if any, on any Security of such series or in respect of a covenant or provision which cannot be modified without the consent

of the Holder of each outstanding Security of the series affected. Any such consent or waiver by the holder of this Note shall be conclusive

and binding upon such holder and upon all future holders and owners of this Note and any Notes which may be issued in exchange or substitution

herefor, irrespective of whether or not any notation thereof is made upon this Note or such other Notes.

No reference herein to the

Indenture and no provision of this Note or of the Indenture shall alter or impair the obligation of the Company, which is absolute and

unconditional, to pay the principal of, if any, and interest on this Note at the place, at the respective times, at the rate and in the

coin or currency herein prescribed.

The Indenture permits the

Company to Discharge its obligations with respect to the Notes on the 91st day following the satisfaction of the conditions set forth

in the Indenture, which include the deposit with the Trustee of money or Foreign Government Securities or a combination thereof sufficient

to pay and discharge each installment of principal of (including premium, if any, on) and interest, if any, on the outstanding Notes.

If the Company shall, in

accordance with Section 901 of the Indenture, consolidate with or merge into any other corporation or convey or transfer its properties

and assets substantially as an entirety to any Person, the successor shall succeed to, and be substituted for, the Person named as the

“Company” on the face of this Note, all on the terms set forth in the Indenture.

The Notes are issuable in

registered form without coupons in denominations of C$2,000 and any integral multiple of C$1,000 in excess thereof. In the manner and

subject to the limitations provided in the Indenture, but without the payment of any service charge, Notes may be exchanged for an equal

aggregate principal amount of Notes of other authorized denominations at the office or agency of the Company maintained for such purpose

in the Borough of Manhattan, The City and State of New York, or any other office or agency designated by the Company for such purpose.

All payments of principal,

interest and additional amounts, if any, including payments made upon any redemption of the Notes, will be made in Canadian dollars.

If Canadian dollars are unavailable to the Company due to the imposition of exchange controls or other circumstances beyond the Company’s

control or if Canadian dollars are no longer used for the settlement of transactions by public institutions of or within the international

banking community, then all payments in respect of this Note will be made in U.S. dollars until Canadian dollars are again available

to the Company or so used. In such circumstances, the amount payable on any date in Canadian dollars will be converted into U.S. dollars

on the basis of the most recently available market exchange rate for the Canadian dollar. Any payment in respect of this Note so made

in U.S. dollars will not constitute an Event of Default as defined in the Indenture.

The Company will, subject

to the exceptions and limitations set forth below, pay as additional interest on this Note such additional amounts as are necessary in

order that the net payment by the Company or a paying agent of the principal of and interest on the Notes to a holder who is not a United

States person (as defined below), after deduction for any present or future tax, assessment or other governmental charge of the United

States or a political subdivision or taxing authority of or in the United States, imposed by withholding with respect to the payment,

will not be less than the amount provided in this Note to be then due and payable; provided, however, that the foregoing obligation to

pay additional amounts shall not apply:

(1)            to

any tax, assessment or other governmental charge that is imposed or withheld solely by reason of the holder, or a fiduciary, settlor,

beneficiary, member or shareholder of the holder if the holder is an estate, trust, partnership or corporation, or a person holding a

power over an estate or trust administered by a fiduciary holder, being considered as:

(a)            being

or having been present or engaged in a trade or business in the United States or having had a permanent establishment in the United States;

(b)            having

(e)            being

a bank receiving payments on an extension of credit made pursuant to a loan agreement entered into in the ordinary course of its trade

or business;

(2)            to

any holder that is not the sole beneficial owner of the Notes, or a portion of the Notes, or that is a fiduciary or partnership, but

only to the extent that a beneficiary or settlor with respect to the fiduciary, a beneficial owner or member of the partnership would

not have been entitled to the payment of an additional amount had the beneficiary, settlor, beneficial owner or member received directly

its beneficial or distributive share of the payment;

(3)            to

any tax, assessment or other governmental charge that is imposed otherwise or withheld solely by reason of a failure of the holder or

any other person to comply with certification, identification or information reporting requirements concerning the nationality, residence,

identity or connection with the United States of the holder or beneficial owner of the Notes, if compliance is required by statute, by

regulation of the United States Treasury Department or by an applicable income tax treaty to which the United States is a party as a

precondition to exemption from such tax, assessment or other governmental charge;

(4)            to

any tax, assessment or other governmental charge that is imposed otherwise than by withholding by the Company or a paying agent from

the payment;

(5)            to

or judicial interpretation that becomes effective more than 15 days after the payment becomes due or is duly provided for, whichever

occurs later;

(6)            to

any estate, inheritance, gift, sales, excise, transfer, wealth or personal property tax or similar tax, assessment or other governmental

charge;

(7)            to

any tax, assessment or other governmental charge required to be withheld by any paying agent from any payment of principal of or interest

on any Notes, if such payment can be made without such withholding by any other paying agent;

(8)            to

any taxes that are imposed or withheld pursuant to Sections 1471 through 1474 of the Code (or any amended or successor version of such

Sections), any Treasury regulations promulgated thereunder, any official interpretations thereof or any agreements entered into in connection

with the implementation thereof;

(9)            with

respect to any payment to the extent such payment could have been made without such deduction or withholding if the holder or beneficial

owner of the Notes had presented the Notes for payment (where presentation is permitted or required for payment) within 30 days after

the date on which such payment became due and payable or date on which payment thereof is duly provided for, whichever is later, except

for additional amounts with respect to taxes that would have been imposed had the Holder or beneficial owner presented the Notes for

payment within such 30-day period; and

(10)          in

the case of any combination of items (1), (2), (3), (4), (5), (6), (7), (8) and (9).

This Note is subject in all

cases to any tax, fiscal or other law or regulation or administrative or judicial interpretation applicable to this Note. Except as specifically

provided in this Note, the Company shall not be required to make any payment with respect to any tax, assessment or other governmental

charge imposed by any government or a political subdivision or taxing authority of, or in any government or political subdivision.

As used in this Note, the

term “United States” means the United States of America (including the states and the District of Columbia) and its territories,

possessions and other areas subject to its jurisdiction, and the term “United States person” means any individual who is

a citizen or resident of the United States, a corporation, partnership or other entity created or organized in or under the laws of the

United States, any state of the United States or the District of Columbia (other than a partnership that is not treated as a United States

person under any applicable Treasury regulations), or any estate or trust the income of which is subject to United States federal income

taxation regardless of its source.

If, as a result of any change

in, or amendment to, the laws (or any regulations or rulings promulgated under the laws) of the United States (or any political subdivision

or taxing authority of or in the United States), or any change in, or amendments to, an official position regarding the application or

interpretation of such laws, regulations or rulings, which change or amendment is announced or becomes effective on or after August 10,

2026, the Company becomes, or based upon a written opinion of independent counsel selected by the Company, will become obligated to pay

additional amounts as described above with respect to this Note, then the Company may at its option redeem, in whole, but not in part,

this Note on not less than 30 nor more than 60 days prior notice, at a redemption price equal to 100% of its principal amount, together

with interest accrued but unpaid on this Note to the date fixed for redemption.

The Notes will be redeemable,

as a whole or in part, at the Company’s option, at any time or from time to time (in C$1,000 increments, provided that any remaining

principal amount thereof shall be at least the minimum authorized denomination thereof), on at least 10 days’, but not more than

60 days’, prior notice (by mail, electronic delivery or otherwise in accordance with the procedures of CDS) to the holders of the

Notes to be redeemed (with a copy to the Trustee and the paying agent). Prior to the Par Call Date, as defined below, the redemption

price for the Notes will be equal to the greater of:

· 100%

of the principal amount of the Notes to be redeemed; and

· the

Canada Yield Price with respect to the Notes to be redeemed,

plus, in each case, accrued and unpaid interest

on the Notes to be redeemed to, but excluding, the Redemption Date.

On and after the Par Call

Date, the redemption price for the Notes will be equal to 100% of the principal amount of the Notes to be redeemed plus accrued and unpaid

interest to, but excluding, the Redemption Date.

“Business Day”

means any day other than a Saturday or Sunday that is not a day on which banking institutions in the City of New York, New York, United

States or Toronto, Ontario, Canada are authorized or required by law or executive order to close.

“Canada Yield Price”

means, in respect of any Notes being redeemed, the price, in respect of the principal amount of such Notes, calculated by the Company

as of the third Business Day prior to the Redemption Date of such Notes, equal to the sum of the present values of the Remaining Scheduled

Payments using a discount rate equal to the Government of Canada Yield on such Business Day plus 30 basis points.

“Government of Canada

Yield” means, on any date, the bid-side yield to maturity on such date as determined by the arithmetic average (rounded to three

decimal places) of the yields quoted at 10:00 a.m. (Toronto time) by any two investment dealers in Canada selected by the Company,

assuming semi-annual compounding and calculated in accordance with generally accepted financial practice, which a non-callable Government

of Canada bond would carry if issued in Canadian dollars in Canada at 100% of its principal amount on such date with a term to maturity

that most closely approximates the remaining term of the Notes to the Par Call Date.

“Par Call Date”

means June 15, 2034 (two months prior to the maturity date of the Notes).

“Remaining Scheduled

Payments” means, with respect to each Note to be redeemed, the remaining scheduled payments of the principal thereof and interest

thereon that would be due after the related Redemption Date if the Note were redeemed on the Par Call Date. If the Redemption Date is

not an interest payment date with respect to such Note, the amount of the next succeeding scheduled interest payment thereon will be

reduced by the amount of interest accrued thereon to, but excluding, the Redemption Date.

The Company will notify the

Trustee and the paying agent of the redemption price promptly after the calculation thereof and the Trustee and the paying agent shall

not be responsible or liable for any calculation of the redemption price or of any component thereof.

On and after the Redemption

Date, interest will cease to accrue on the Notes or any portion thereof called for redemption (unless we default in the payment of the

redemption price and accrued and unpaid interest). On or before the Redemption Date, we will deposit with a paying agent money sufficient

to pay the redemption price of and accrued and unpaid interest on the Notes to be redeemed on that date.

If any Note is to be redeemed

in part, such Note must be redeemed in a minimum principal amount of C$1,000 and in integral multiples of C$1,000 in principal amount

in excess thereof (provided that any remaining principal amount thereof shall be at least the minimum authorized denomination thereof).

For so long as the Notes are held by CDS, the redemption and the selection of Notes to be redeemed shall be in accordance with the policies

and procedures of CDS and its participants.

Upon due presentation for

registration of transfer of this Note at the office or agency of the Company for such registration in the Borough of Manhattan, The City

and State of New York, or any other office or agency designated by the Company for such purpose, a new Note or Notes of authorized denominations

for an equal aggregate principal amount will be issued to the transferee in exchange herefor, subject to the limitations provided in

the Indenture, without charge except for any tax or other governmental charge imposed in connection therewith.

Prior to due presentment

for registration of transfer of this Note, the Company, the Trustee and any agent of the Company or the Trustee may deem and treat the

registered holder hereof as the absolute owner of this Note (whether or not this Note shall be overdue) for the purpose of receiving

payment of the principal of, premium, if any, and interest on this Note, as herein provided, and for all other purposes, and neither

the Company nor the Trustee nor any agent of the Company or the Trustee shall be affected by any notice of the contrary. All payments

made to or upon the order of such registered holder shall, to the extent of the sum or sums paid, effectually satisfy and discharge liability

for moneys payable on this Note.

If the Company issues definitive

Notes, interest on such Notes will be payable either by check mailed to each holder or, upon application by a holder to the registrar

not later than the relevant record date, by wire transfer in immediately available funds to that holder’s account, which application

shall remain in effect until the holder notifies the registrar, in writing, to the contrary.

No recourse for the payment

of the principal of, premium, if any, or interest on this Note, or for any claim based hereon or otherwise in respect hereof, and no

recourse under or upon any obligation, covenant or agreement of the Company in the Indenture or any indenture supplemental thereto or

in any Note, or because of the creation of any indebtedness represented thereby, shall be had against any incorporator, stockholder,

officer or director, as such, past, present or future, of the Company or of any successor corporation, either directly or through the

Company or any successor corporation, whether by virtue of any constitution, statute or rule of law or by the enforcement of any

assessment or penalty or otherwise, all such liability being, by the acceptance hereof and as part of the consideration for the issue

hereof, expressly waived and released. Unless otherwise defined in this Note, all terms used in this Note which are defined in the Indenture

shall have the meanings assigned to them in the Indenture.

THIS NOTE SHALL BE GOVERNED

BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK.

INTERNATIONAL BUSINESS MACHINES CORPORATION

Office of the Vice President, Assistant General

Counsel and Secretary

Armonk, New York 10504

August 14, 2026

International Business Machines Corporation

One New Orchard Road

Armonk, NY 10504

Ladies and Gentlemen:

I am the Vice President, Assistant

General Counsel and Secretary of International Business Machines Corporation (herein called the “Company”) and an attorney

duly admitted to practice in the State of New York.

The Company has filed with

the Securities and Exchange Commission a Registration Statement on Form S-3 (File No. 333-276739) (the “Registration Statement”)

for the purpose of registering under the Securities Act of 1933, as amended (the “Securities Act”), debt and other securities

to be issued from time to time by the Company, including C$1,750,000,000 aggregate principal amount of the Company’s 4.100% Notes

due 2030 and C$1,000,000,000 aggregate principal amount of the Company’s 4.750% Notes due 2034 (together, the “Securities”).

The Securities are to be issued

pursuant to the Indenture (the “Indenture”) dated as of October 1, 1993, between the Company and The Bank of New York Mellon,

as trustee (the “Trustee”), as supplemented by the First Supplemental Indenture dated as of December 15, 1995. The Securities

are to be sold pursuant to the Underwriting Agreement dated August 10, 2026 (the “Underwriting Agreement”) among the Company

and the several underwriters named therein (the “Underwriters”).

I, working together with members

of the Company’s legal department, have reviewed such documents and records as I have deemed necessary or appropriate to enable

me to express an informed and reasoned legal opinion with respect to the matters covered hereby. I am also familiar with the proceedings

by which such instruments and the transactions contemplated thereby were authorized by the Company.

Based on the foregoing, I

am of the opinion that the Securities, when executed and authenticated in accordance with the provisions of the Indenture and delivered

to and paid for by the Underwriters pursuant to the Underwriting Agreement, and assuming that the Securities are duly authenticated by

or on behalf of the Trustee, will be validly issued and will constitute valid and binding obligations of the Company, enforceable against

the Company in accordance with their terms (subject to applicable bankruptcy, insolvency, reorganization, fraudulent conveyance, moratorium

or other similar laws in effect and subject to general principles of equity, regardless of whether such enforceability is considered in

a proceeding in equity or at law).

In giving this opinion, I

express no opinion as to any laws other than the laws of the State of New York and the Federal Laws of the United States of America.

I hereby consent to the filing

of this opinion letter as Exhibit 5.1 to the Company’s Current Report on Form 8-K dated August 14, 2026, its incorporation into

the Registration Statement and to the use of my name under the caption “Legal Opinions” in the prospectus supplements relating

to the Securities included in the Registration Statement. In giving this consent, I do not admit that I am within the category of persons

whose consent is required under Section 7 of the Securities Act.

Very truly yours,
