4.875% Series NN Notes due 2029

MARRIOTT INTERNATIONAL, INC., a corporation duly organized and existing under the laws of Delaware (herein called the “Company,” which term includes any successor Person under the Indenture hereinafter referred to), for value received, hereby promises to pay to Cede & Co., or registered assigns, the principal sum of     Dollars on May 15, 2029 and to pay interest thereon from February 22, 2024, semi-annually on May 15 and November 15 in each year, commencing on May 15, 2024, at the rate of 4.875% per annum until the principal hereof is paid or made available for payment.

All such payments of principal, interest and premium, if any, shall be paid in immediately available funds. The interest so payable, and punctually paid or duly provided for, on any Interest Payment Date will, as provided in such Indenture, be paid to the Person in whose name this Security (or one or more Predecessor Securities) is registered at the close of business on the Regular Record Date for such interest, which shall be the May 1 or November 1 (whether or not a Business Day), as the case may be, next preceding such Interest Payment Date. Any such interest not so punctually paid or duly provided for will forthwith cease to be payable to the Holder on such Regular Record Date and may either be paid to the Person in whose name this Security (or one or more Predecessor Securities) is registered at the close of business on a Special Record Date for the payment of such Defaulted Interest to be fixed by the Trustee, notice whereof shall be given to Holders of Securities of this series not less than 10 days prior to such Special Record Date, or be paid at any time in any other lawful manner not inconsistent with the requirements of any securities exchange on which the Securities of this series may be listed, and upon such notice as may be required by such exchange, all as more fully provided in said Indenture.

Payment of the principal of (and premium, if any) and interest on this Security will be made at the office or agency of the Trustee maintained for that purpose in New York, New York, in such coin or currency of the United States of America as at the time of payment is legal tender for payment of public and private debts; provided, however, that payment of interest may be made by check mailed to the address of the Person entitled thereto as such address shall appear in the Security Register; and provided, further, that notwithstanding the foregoing, the Person in whose name this Security is registered may elect to receive payments of interest on this Security (other than at Maturity) by electronic funds transfer of immediately available funds to an account maintained by such Person, provided such Person so elects by giving written notice to a Paying Agent designating such account, no later than the May 1 or November 1 immediately preceding the May 15 or November 15 Interest Payment Date, as the case may be. Unless such designation is revoked by such Person, any such designation made by such Person with respect to such Securities shall remain in effect with respect to any future payments with respect to such Securities payable to such Person. If any Interest Payment Date, the stated maturity date or redemption or repurchase date for the Securities is not a Business Day, the payment otherwise required to be made on such date will be made on the next Business Day without any additional payment as a result of such delay.

Reference is hereby made to the further provisions of this Security set forth on the reverse hereof, which further provisions shall for all purposes have the same effect as if set forth at this place.

Unless the certificate of authentication hereon has been executed by the Trustee referred to on the reverse hereof by manual, electronic or facsimile signature, this Security shall not be entitled to any benefit under the Indenture or be valid or obligatory for any purpose.

[Signature Page – Global Note]

[Reverse of Security]

This Security is one of a duly authorized issue of securities of the Company (herein called the “Securities”), issued and to be issued in one or more series under an Indenture, dated as of November 16, 1998 (herein called the “Indenture”, which term shall have the meaning assigned to it in such instrument), between the Company and The Bank of New York Mellon, successor to JPMorgan Chase Bank, N.A., formerly known as The Chase Manhattan Bank, as Trustee (herein called the “Trustee”, which term includes any successor trustee under the Indenture), and reference is hereby made to the Indenture for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee and the Holders of the Securities and of the terms upon which the Securities are, and are to be, authenticated and delivered, as modified by the provisions set forth below and on the face hereof. This Security is one of the series designated on the face hereof, limited initially in aggregate principal amount to $500,000,000. The Company may subsequently issue additional securities as part of this series of Securities under the Indenture.

The Company may redeem the Securities in whole or in part, at any time and from time to time, at its option, prior to April 15, 2029 (one month prior to the maturity date of the Securities) (the “Par Call Date”), at a Redemption Price (expressed as a percentage of principal amount and rounded to three decimal places) equal to the greater of (1) (a) the sum of the present values of the remaining scheduled payments of principal and interest thereon discounted to the Redemption Date (assuming the Securities matured on the Par Call Date) on a semiannual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate plus 15 basis points less (b) interest accrued to the date of redemption, and (2) 100% of the principal amount of the Securities to be redeemed, plus, in either case, accrued and unpaid interest thereon to the Redemption Date.

On or after the Par Call Date, the Company may redeem the Securities in whole or in part, at any time and from time to time, at its option, at a Redemption Price equal to 100% of the principal amount of the Securities being redeemed plus accrued and unpaid interest thereon to the Redemption Date.

The Company’s actions and determinations in determining the Redemption Price shall be conclusive and binding for all purposes, absent manifest error.

Notice of any redemption shall be mailed or electronically delivered (or otherwise transmitted in accordance with the depositary’s procedures) at least 10 days but not more than 60 days before the Redemption Date to each Holder of Securities to be redeemed.

In the case of a partial redemption, selection of the Securities for redemption shall be made by lot. No Securities of a principal amount of $2,000 or less shall be redeemed in part. If any Security is to be redeemed in part only, the notice of redemption that relates to the Security shall state the portion of the principal amount of the Security to be redeemed. A new Security in a principal amount equal to the unredeemed portion of the Security shall be issued in the name of the Holder of the Security upon surrender for cancellation of the original Security. For so long as the Securities are held by DTC (or another Depositary), the redemption of the Securities shall be done in accordance with the policies and procedures of the Depositary.

Unless the Company defaults in payment of the Redemption Price, on and after the Redemption Date, interest will cease to accrue on the Securities or portions thereof called for redemption.

1

“Treasury Rate” means, with respect to any Redemption Date, the yield determined by the Company in accordance with the following two paragraphs.

The Treasury Rate shall be determined by the Company after 4:15 p.m., New York City time (or after such time as yields on U.S. government securities are posted daily by the Board of Governors of the Federal Reserve System), on the third business day preceding the date of the notice of redemption based upon the yield or yields for the most recent day that appear after such time on such day in the most recent statistical release published by the Board of Governors of the Federal Reserve System designated as “Selected Interest Rates (Daily)—H.15” (or any successor designation or publication) (“H.15”) under the caption “U.S. government securities–Treasury constant maturities–Nominal” (or any successor caption or heading). In determining the Treasury Rate, the Company shall select, as applicable: (1) the yield for the Treasury constant maturity on H.15 exactly equal to the period from the Redemption Date to the Par Call Date (the “Remaining Life”); or (2) if there is no such Treasury constant maturity on H.15 exactly equal to the Remaining Life, the two yields – one yield corresponding to the Treasury constant maturity on H.15 immediately shorter than and one yield corresponding to the Treasury constant maturity on H.15 immediately longer than the Remaining Life – and shall interpolate to the Par Call Date on a straight-line basis (using the actual number of days) using such yields and rounding the result to three decimal places; or (3) if there is no such Treasury constant maturity on H.15 shorter than or longer than the Remaining Life, the yield for the single Treasury constant maturity on H.15 closest to the Remaining Life. For purposes of this paragraph, the applicable Treasury constant maturity or maturities on H.15 shall be deemed to have a maturity date equal to the relevant number of months or years, as applicable, of such Treasury constant maturity from the Redemption Date.

If on the third business day preceding the date of the notice of redemption H.15 or any successor designation or publication is no longer published, the Company shall calculate the Treasury Rate based on the rate per annum equal to the semiannual equivalent yield to maturity at 11:00 a.m., New York City time, on the second business day preceding such redemption notice date of the United States Treasury security maturing on, or with a maturity that is closest to, the Par Call Date, as applicable. If there is no United States Treasury security maturing on the Par Call Date but there are two or more United States Treasury securities with a maturity date equally distant from the Par Call Date, one with a maturity date preceding the Par Call Date and one with a maturity date following the Par Call Date, the Company shall select the United States Treasury security with a maturity date preceding the Par Call Date. If there are two or more United States Treasury securities maturing on the Par Call Date or two or more United States Treasury securities meeting the criteria of the preceding sentence, the Company shall select from among these two or more United States Treasury securities the United States Treasury security that is trading closest to par based upon the average of the bid and asked prices for such United States Treasury securities at 11:00 a.m., New York City time. In determining the Treasury Rate in accordance with the terms of this paragraph, the semiannual yield to maturity of the applicable United States Treasury security shall be based upon the average of the bid and asked prices (expressed as a percentage of principal amount) at 11:00 a.m., New York City time, of such United States Treasury security, and rounded to three decimal places.

If a Change of Control Repurchase Event (as defined below) occurs, unless the Company has exercised its right to redeem the Securities of this series, the Company will make an offer to each Holder of the Securities of this series to repurchase all or any part (in excess of $2,000 in integral multiples of $1,000) of that Holder’s Securities of this series at a repurchase price in cash equal to 101% of the aggregate principal amount of the Securities of this series repurchased plus

2

any accrued and unpaid interest on the Securities of this series repurchased to the date of purchase. Within 30 days following any Change of Control Repurchase Event or, at the Company’s option, prior to any Change of Control (as defined below), but after the public announcement of the Change of Control, the Company will deliver a notice to each Holder, with a copy to the Trustee, describing the transaction or transactions that constitute or may constitute the Change of Control Repurchase Event and offering to repurchase the Securities of this series on the payment date specified in the notice, which date will be no earlier than 30 days and no later than 60 days from the date such notice is sent. The notice shall, if sent prior to the date of consummation of the Change of Control, state that the offer to purchase is conditioned on the Change of Control Repurchase Event occurring on or prior to the payment date specified in the notice. The Company will comply with the requirements of Rule 14e-1 under the Securities Exchange Act of 1934, as amended, and any other securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with the repurchase of the Securities of this series as a result of a Change of Control Repurchase Event. To the extent that the provisions of any securities laws or regulations conflict with the Change of Control Repurchase Event provisions herein, the Company will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under the Change of Control Repurchase Event provisions herein by virtue of such conflict.

On the Change of Control Repurchase Event payment date, the Company will, to the extent lawful:

1. accept for payment all Securities of this series or portions of Securities of this series properly tendered pursuant to the Company’s offer;

2. deposit with the Paying Agent an amount equal to the aggregate purchase price in respect of all Securities of this series or portions of Securities of this series properly tendered; and

3. deliver or cause to be delivered to the Trustee the Securities of this series properly accepted, together with an Officers’ Certificate stating the aggregate principal amount of the Securities being purchased by the Company.

The Paying Agent will promptly pay to each Holder of the Securities of this series properly tendered the purchase price for the Securities, and the Trustee will promptly authenticate and deliver (or cause to be transferred by book-entry) to each Holder a new Security equal in principal amount to any unpurchased portion of any Securities surrendered; provided that each new Security will be in a principal amount of $2,000 or an integral multiple of $1,000.

The Company will not be required to make an offer to repurchase the Securities of this series upon a Change of Control Repurchase Event if a third party makes such an offer in the manner, at the times and otherwise in compliance with the requirements for an offer made by the Company and such third party purchases all Securities of this series properly tendered and not withdrawn under its offer.

“Below Investment Grade Rating Event” means the Securities of this series are rated below Investment Grade (as defined below) by both Rating Agencies (as defined below) on any date from the date of the public notice of an arrangement that could result in a Change of Control until the end of the 60-day period following public notice of the occurrence of a Change of Control (which

3

period shall be extended so long as the rating of the Securities of this series is under publicly announced consideration for possible downgrade by either of the Rating Agencies); provided that a Below Investment Grade Rating Event otherwise arising by virtue of a particular reduction in rating shall not be deemed to have occurred in respect of a particular Change of Control (and thus shall not be deemed a Below Investment Grade Rating Event for purposes of the definition of Change of Control Repurchase Event herein) if the Rating Agencies making the reduction in rating to which this definition would otherwise apply do not announce or publicly confirm or inform the Company in writing at its request that the reduction was the result, in whole or in part, of any event or circumstance comprised of or arising as a result of, or in respect of, the applicable Change of Control (whether or not the applicable Change of Control shall have occurred at the time of the Below Investment Grade Rating Event).

“Change of Control” means the consummation of any transaction (including, without limitation, any merger or consolidation) the result of which is that any “person” (as that term is used in Section 13(d)(3) of the Securities Exchange Act of 1934, as amended) becomes the beneficial owner, directly or indirectly, of more than 50% of the Company’s Voting Stock, measured by voting power rather than number of shares. Notwithstanding the foregoing, a transaction effected to create a holding company for the Company will not be deemed to involve a Change of Control if: (1) pursuant to such transaction the Company becomes a direct or indirect wholly owned subsidiary of such holding company and (2)(A) the direct or indirect holders of the Voting Stock of such holding company immediately following that transaction are substantially the same as the holders of the Company’s Voting Stock immediately prior to that transaction or (B) immediately following that transaction no person (other than a holding company satisfying the requirements of this sentence) is the beneficial owner, directly or indirectly, of more than 50% of the Voting Stock of such holding company, measured by voting power rather than number of shares.

“Change of Control Repurchase Event” means the occurrence of both a Change of Control and a Below Investment Grade Rating Event.

“Investment Grade” means a rating of Baa3 or better by Moody’s (or its equivalent under any successor rating categories of Moody’s); a rating of BBB- or better by S&P (or its equivalent under any successor rating categories of S&P); and the equivalent investment grade credit rating from any replacement Rating Agency or Rating Agencies selected by the Company.

“Moody’s” means Moody’s Investors Service, Inc. and its successors.

“Rating Agency” means (1) each of Moody’s and S&P; and (2) if either of Moody’s or S&P ceases to rate the Securities of this series or fails to make a rating of the Securities of this series publicly available for reasons outside of the Company’s control, a Substitute Rating Agency.

“S&P” means S&P Global Ratings and its successors.

“Substitute Rating Agency” means a “nationally recognized statistical rating organization” within the meaning of Section 3(a)(62) under the Securities Exchange Act of 1934, as amended, selected by the Company (as certified by a resolution of the Company’s board of directors) as a replacement agency for Moody’s or S&P, or both, as the case may be.

4

“Voting Stock” of any specified “person” (as that term is used in Section 13(d)(3) of the Securities Exchange Act of 1934, as amended) as of any date means the capital stock of such person that is at the time entitled to vote generally in the election of the board of directors of such person.

The Indenture contains provisions for defeasance at any time of the entire indebtedness of this Security or certain restrictive covenants and Events of Default with respect to this Security, in each case upon compliance with certain conditions set forth in the Indenture.

If an Event of Default with respect to Securities of this series shall occur and be continuing, the principal of the Securities of this series may be declared due and payable in the manner and with the effect provided in the Indenture.

The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the rights of the Holders of the Securities of each series to be affected under the Indenture at any time by the Company and the Trustee with the consent of the Holders of 50% in principal amount of the Securities at the time Outstanding of each series to be affected. The Indenture also contains provisions permitting the Holders of specified percentages in principal amount of the Securities of each series at the time Outstanding, on behalf of the Holders of all Securities of such series, to waive compliance by the Company with certain provisions of the Indenture and certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Security shall be conclusive and binding upon such Holder and upon all future Holders of this Security and of any Security issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Security.

As provided in and subject to the provisions of the Indenture, the Holder of this Security shall not have the right to institute any proceeding with respect to the Indenture or for the appointment of a receiver or trustee or for any other remedy thereunder, unless such Holder shall have previously given the Trustee written notice of a continuing Event of Default with respect to the Securities of this series, the Holders of not less than 25% in principal amount of the Securities of this series at the time Outstanding shall have made written request to the Trustee to institute proceedings in respect of such Event of Default as Trustee and offered the Trustee indemnity satisfactory to it, and the Trustee shall not have received from the Holders of a majority in principal amount of Securities of this series at the time Outstanding a direction inconsistent with such request, and shall have failed to institute any such proceeding, for 60 days after receipt of such notice, request and offer of indemnity. The foregoing shall not apply to any suit instituted by the Holder of this Security for the enforcement of any payment of principal hereof or any premium or interest hereon on or after the respective due dates expressed herein.

No reference herein to the Indenture and no provision of this Security or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of and any premium and interest on this Security at the times, place and rate, and in the coin or currency, herein prescribed.

As provided in the Indenture and subject to certain limitations therein set forth, the transfer of this Security is registrable in the Security Register, upon surrender of this Security for registration of transfer at the office or agency of the Trustee in any place where the principal of and any premium and interest on this Security are payable, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Company and the Security Registrar duly executed by, the Holder hereof or his attorney duly authorized in writing, and thereupon one or more new Securities of this series and of like tenor, of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees.

5

The Securities of this series are issuable only in registered form without coupons in denominations of $2,000 and integral multiples of $1,000 in excess thereof. As provided in the Indenture and subject to certain limitations therein set forth, Securities of this series are exchangeable for a like aggregate principal amount of Securities of this series and of like tenor of a different authorized denomination, as requested by the Holder surrendering the same.

In addition to the circumstances specified in Clause (2) of the last paragraph of Section 305 of the Indenture in which a Global Security of such series may be exchanged in whole or in part for Securities of such series registered, and any transfer of such Global Security in whole or in part may be registered, in the name of Persons other than the Depositary for such Global Security or a nominee thereof, the Company may, in its sole discretion, determine that such Global Security will be exchangeable for Securities registered in the name of Persons other than the Depositary or a nominee thereof and notify the Trustee of its decision.

No service charge shall be made for any such registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith.

Prior to due presentment of this Security for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name this Security is registered as the owner hereof for all purposes, whether or not this Security be overdue, and neither the Company, the Trustee nor any such agent shall be affected by notice to the contrary.

All terms used in this Security which are defined in the Indenture shall have the meanings assigned to them in the Indenture.

Payment of the principal of (and premium, if any) and interest on this Security will be made at the office or agency of the Trustee maintained for that purpose in New York, New York, in such coin or currency of the United States of America as at the time of payment is legal tender for payment of public and private debts; provided, however, that payment of interest may be made by check mailed to the address of the Person entitled thereto as such address shall appear in the Security Register; and provided, further, that notwithstanding the foregoing, the Person in whose name this Security is registered may elect to receive payments of interest on this Security (other than at Maturity) by electronic funds transfer of immediately available funds to an account maintained by such Person, provided such Person so elects by giving written notice to a Paying Agent designating such account, no later than the May 1 or November 1 immediately preceding the May 15 or November 15 Interest Payment Date, as the case may be. Unless such designation is revoked by such Person, any such designation made by such Person with respect to such Securities shall remain in effect with respect to any future payments with respect to such Securities payable to such Person. If any Interest Payment Date, the stated maturity date or redemption or repurchase date for the Securities is not a Business Day, the payment otherwise required to be made on such date will be made on the next Business Day without any additional payment as a result of such delay.

Reference is hereby made to the further provisions of this Security set forth on the reverse hereof, which further provisions shall for all purposes have the same effect as if set forth at this place.

Unless the certificate of authentication hereon has been executed by the Trustee referred to on the reverse hereof by manual, electronic or facsimile signature, this Security shall not be entitled to any benefit under the Indenture or be valid or obligatory for any purpose.

This is one of the Securities of the series designated therein referred to in the within-mentioned Indenture.

[Signature Page – Global Note]

[Reverse of Security]

This Security is one of a duly authorized issue of securities of the Company (herein called the “Securities”), issued and to be issued in one or more series under an Indenture, dated as of November 16, 1998 (herein called the “Indenture”, which term shall have the meaning assigned to it in such instrument), between the Company and The Bank of New York Mellon, successor to JPMorgan Chase Bank, N.A., formerly known as The Chase Manhattan Bank, as Trustee (herein called the “Trustee”, which term includes any successor trustee under the Indenture), and reference is hereby made to the Indenture for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee and the Holders of the Securities and of the terms upon which the Securities are, and are to be, authenticated and delivered, as modified by the provisions set forth below and on the face hereof. This Security is one of the series designated on the face hereof, limited initially in aggregate principal amount to $1,000,000,000. The Company may subsequently issue additional securities as part of this series of Securities under the Indenture.

The Company may redeem the Securities in whole or in part, at any time and from time to time, at its option, prior to February 15, 2034 (three months prior to the maturity date of the Securities) (the “Par Call Date”), at a Redemption Price (expressed as a percentage of principal amount and rounded to three decimal places) equal to the greater of (1) (a) the sum of the present values of the remaining scheduled payments of principal and interest thereon discounted to the Redemption Date (assuming the Securities matured on the Par Call Date) on a semiannual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate plus 20 basis points less (b) interest accrued to the date of redemption, and (2) 100% of the principal amount of the Securities to be redeemed, plus, in either case, accrued and unpaid interest thereon to the Redemption Date.

On or after the Par Call Date, the Company may redeem the Securities in whole or in part, at any time and from time to time, at its option, at a Redemption Price equal to 100% of the principal amount of the Securities being redeemed plus accrued and unpaid interest thereon to the Redemption Date.

The Company’s actions and determinations in determining the Redemption Price shall be conclusive and binding for all purposes, absent manifest error.

Notice of any redemption shall be mailed or electronically delivered (or otherwise transmitted in accordance with the depositary’s procedures) at least 10 days but not more than 60 days before the Redemption Date to each Holder of Securities to be redeemed.

In the case of a partial redemption, selection of the Securities for redemption shall be made by lot. No Securities of a principal amount of $2,000 or less shall be redeemed in part. If any Security is to be redeemed in part only, the notice of redemption that relates to the Security shall state the portion of the principal amount of the Security to be redeemed. A new Security in a principal amount equal to the unredeemed portion of the Security shall be issued in the name of the Holder of the Security upon surrender for cancellation of the original Security. For so long as the Securities are held by DTC (or another Depositary), the redemption of the Securities shall be done in accordance with the policies and procedures of the Depositary.

1

Unless the Company defaults in payment of the Redemption Price, on and after the Redemption Date, interest will cease to accrue on the Securities or portions thereof called for redemption.

“Treasury Rate” means, with respect to any Redemption Date, the yield determined by the Company in accordance with the following two paragraphs.

The Treasury Rate shall be determined by the Company after 4:15 p.m., New York City time (or after such time as yields on U.S. government securities are posted daily by the Board of Governors of the Federal Reserve System), on the third business day preceding the date of the notice of redemption based upon the yield or yields for the most recent day that appear after such time on such day in the most recent statistical release published by the Board of Governors of the Federal Reserve System designated as “Selected Interest Rates (Daily)—H.15” (or any successor designation or publication) (“H.15”) under the caption “U.S. government securities–Treasury constant maturities–Nominal” (or any successor caption or heading). In determining the Treasury Rate, the Company shall select, as applicable: (1) the yield for the Treasury constant maturity on H.15 exactly equal to the period from the Redemption Date to the Par Call Date (the “Remaining Life”); or (2) if there is no such Treasury constant maturity on H.15 exactly equal to the Remaining Life, the two yields – one yield corresponding to the Treasury constant maturity on H.15 immediately shorter than and one yield corresponding to the Treasury constant maturity on H.15 immediately longer than the Remaining Life – and shall interpolate to the Par Call Date on a straight-line basis (using the actual number of days) using such yields and rounding the result to three decimal places; or (3) if there is no such Treasury constant maturity on H.15 shorter than or longer than the Remaining Life, the yield for the single Treasury constant maturity on H.15 closest to the Remaining Life. For purposes of this paragraph, the applicable Treasury constant maturity or maturities on H.15 shall be deemed to have a maturity date equal to the relevant number of months or years, as applicable, of such Treasury constant maturity from the Redemption Date.

If on the third business day preceding the date of the notice of redemption H.15 or any successor designation or publication is no longer published, the Company shall calculate the Treasury Rate based on the rate per annum equal to the semiannual equivalent yield to maturity at 11:00 a.m., New York City time, on the second business day preceding such redemption notice date of the United States Treasury security maturing on, or with a maturity that is closest to, the Par Call Date, as applicable. If there is no United States Treasury security maturing on the Par Call Date but there are two or more United States Treasury securities with a maturity date equally distant from the Par Call Date, one with a maturity date preceding the Par Call Date and one with a maturity date following the Par Call Date, the Company shall select the United States Treasury security with a maturity date preceding the Par Call Date. If there are two or more United States Treasury securities maturing on the Par Call Date or two or more United States Treasury securities meeting the criteria of the preceding sentence, the Company shall select from among these two or more United States Treasury securities the United States Treasury security that is trading closest to par based upon the average of the bid and asked prices for such United States Treasury securities at 11:00 a.m., New York City time. In determining the Treasury Rate in accordance with the terms of this paragraph, the semiannual yield to maturity of the applicable United States Treasury security shall be based upon the average of the bid and asked prices (expressed as a percentage of principal amount) at 11:00 a.m., New York City time, of such United States Treasury security, and rounded to three decimal places.

2

If a Change of Control Repurchase Event (as defined below) occurs, unless the Company has exercised its right to redeem the Securities of this series, the Company will make an offer to each Holder of the Securities of this series to repurchase all or any part (in excess of $2,000 in integral multiples of $1,000) of that Holder’s Securities of this series at a repurchase price in cash equal to 101% of the aggregate principal amount of the Securities of this series repurchased plus any accrued and unpaid interest on the Securities of this series repurchased to the date of purchase. Within 30 days following any Change of Control Repurchase Event or, at the Company’s option, prior to any Change of Control (as defined below), but after the public announcement of the Change of Control, the Company will deliver a notice to each Holder, with a copy to the Trustee, describing the transaction or transactions that constitute or may constitute the Change of Control Repurchase Event and offering to repurchase the Securities of this series on the payment date specified in the notice, which date will be no earlier than 30 days and no later than 60 days from the date such notice is sent. The notice shall, if sent prior to the date of consummation of the Change of Control, state that the offer to purchase is conditioned on the Change of Control Repurchase Event occurring on or prior to the payment date specified in the notice. The Company will comply with the requirements of Rule 14e-1 under the Securities Exchange Act of 1934, as amended, and any other securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with the repurchase of the Securities of this series as a result of a Change of Control Repurchase Event. To the extent that the provisions of any securities laws or regulations conflict with the Change of Control Repurchase Event provisions herein, the Company will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under the Change of Control Repurchase Event provisions herein by virtue of such conflict.

On the Change of Control Repurchase Event payment date, the Company will, to the extent lawful:

1. accept for payment all Securities of this series or portions of Securities of this series properly tendered pursuant to the Company’s offer;

2. deposit with the Paying Agent an amount equal to the aggregate purchase price in respect of all Securities of this series or portions of Securities of this series properly tendered; and

3. deliver or cause to be delivered to the Trustee the Securities of this series properly accepted, together with an Officers’ Certificate stating the aggregate principal amount of the Securities being purchased by the Company.

The Paying Agent will promptly pay to each Holder of the Securities of this series properly tendered the purchase price for the Securities, and the Trustee will promptly authenticate and deliver (or cause to be transferred by book-entry) to each Holder a new Security equal in principal amount to any unpurchased portion of any Securities surrendered; provided that each new Security will be in a principal amount of $2,000 or an integral multiple of $1,000.

The Company will not be required to make an offer to repurchase the Securities of this series upon a Change of Control Repurchase Event if a third party makes such an offer in the manner, at the times and otherwise in compliance with the requirements for an offer made by the Company and such third party purchases all Securities of this series properly tendered and not withdrawn under its offer.

3

“Below Investment Grade Rating Event” means the Securities of this series are rated below Investment Grade (as defined below) by both Rating Agencies (as defined below) on any date from the date of the public notice of an arrangement that could result in a Change of Control until the end of the 60-day period following public notice of the occurrence of a Change of Control (which period shall be extended so long as the rating of the Securities of this series is under publicly announced consideration for possible downgrade by either of the Rating Agencies); provided that a Below Investment Grade Rating Event otherwise arising by virtue of a particular reduction in rating shall not be deemed to have occurred in respect of a particular Change of Control (and thus shall not be deemed a Below Investment Grade Rating Event for purposes of the definition of Change of Control Repurchase Event herein) if the Rating Agencies making the reduction in rating to which this definition would otherwise apply do not announce or publicly confirm or inform the Company in writing at its request that the reduction was the result, in whole or in part, of any event or circumstance comprised of or arising as a result of, or in respect of, the applicable Change of Control (whether or not the applicable Change of Control shall have occurred at the time of the Below Investment Grade Rating Event).

“Change of Control” means the consummation of any transaction (including, without limitation, any merger or consolidation) the result of which is that any “person” (as that term is used in Section 13(d)(3) of the Securities Exchange Act of 1934, as amended) becomes the beneficial owner, directly or indirectly, of more than 50% of the Company’s Voting Stock, measured by voting power rather than number of shares. Notwithstanding the foregoing, a transaction effected to create a holding company for the Company will not be deemed to involve a Change of Control if: (1) pursuant to such transaction the Company becomes a direct or indirect wholly owned subsidiary of such holding company and (2)(A) the direct or indirect holders of the Voting Stock of such holding company immediately following that transaction are substantially the same as the holders of the Company’s Voting Stock immediately prior to that transaction or (B) immediately following that transaction no person (other than a holding company satisfying the requirements of this sentence) is the beneficial owner, directly or indirectly, of more than 50% of the Voting Stock of such holding company, measured by voting power rather than number of shares.

“Change of Control Repurchase Event” means the occurrence of both a Change of Control and a Below Investment Grade Rating Event.

“Investment Grade” means a rating of Baa3 or better by Moody’s (or its equivalent under any successor rating categories of Moody’s); a rating of BBB- or better by S&P (or its equivalent under any successor rating categories of S&P); and the equivalent investment grade credit rating from any replacement Rating Agency or Rating Agencies selected by the Company.

“Moody’s” means Moody’s Investors Service, Inc. and its successors.

“Rating Agency” means (1) each of Moody’s and S&P; and (2) if either of Moody’s or S&P ceases to rate the Securities of this series or fails to make a rating of the Securities of this series publicly available for reasons outside of the Company’s control, a Substitute Rating Agency.

“S&P” means S&P Global Ratings and its successors.

“Substitute Rating Agency” means a “nationally recognized statistical rating organization” within the meaning of Section 3(a)(62) under the Securities Exchange Act of 1934, as amended, selected by the Company (as certified by a resolution of the Company’s board of directors) as a replacement agency for Moody’s or S&P, or both, as the case may be.

4

“Voting Stock” of any specified “person” (as that term is used in Section 13(d)(3) of the Securities Exchange Act of 1934, as amended) as of any date means the capital stock of such person that is at the time entitled to vote generally in the election of the board of directors of such person.

The Indenture contains provisions for defeasance at any time of the entire indebtedness of this Security or certain restrictive covenants and Events of Default with respect to this Security, in each case upon compliance with certain conditions set forth in the Indenture.

If an Event of Default with respect to Securities of this series shall occur and be continuing, the principal of the Securities of this series may be declared due and payable in the manner and with the effect provided in the Indenture.

The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the rights of the Holders of the Securities of each series to be affected under the Indenture at any time by the Company and the Trustee with the consent of the Holders of 50% in principal amount of the Securities at the time Outstanding of each series to be affected. The Indenture also contains provisions permitting the Holders of specified percentages in principal amount of the Securities of each series at the time Outstanding, on behalf of the Holders of all Securities of such series, to waive compliance by the Company with certain provisions of the Indenture and certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Security shall be conclusive and binding upon such Holder and upon all future Holders of this Security and of any Security issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Security.

As provided in and subject to the provisions of the Indenture, the Holder of this Security shall not have the right to institute any proceeding with respect to the Indenture or for the appointment of a receiver or trustee or for any other remedy thereunder, unless such Holder shall have previously given the Trustee written notice of a continuing Event of Default with respect to the Securities of this series, the Holders of not less than 25% in principal amount of the Securities of this series at the time Outstanding shall have made written request to the Trustee to institute proceedings in respect of such Event of Default as Trustee and offered the Trustee indemnity satisfactory to it, and the Trustee shall not have received from the Holders of a majority in principal amount of Securities of this series at the time Outstanding a direction inconsistent with such request, and shall have failed to institute any such proceeding, for 60 days after receipt of such notice, request and offer of indemnity. The foregoing shall not apply to any suit instituted by the Holder of this Security for the enforcement of any payment of principal hereof or any premium or interest hereon on or after the respective due dates expressed herein.

No reference herein to the Indenture and no provision of this Security or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of and any premium and interest on this Security at the times, place and rate, and in the coin or currency, herein prescribed.

5

As provided in the Indenture and subject to certain limitations therein set forth, the transfer of this Security is registrable in the Security Register, upon surrender of this Security for registration of transfer at the office or agency of the Trustee in any place where the principal of and any premium and interest on this Security are payable, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Company and the Security Registrar duly executed by, the Holder hereof or his attorney duly authorized in writing, and thereupon one or more new Securities of this series and of like tenor, of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees.

The Securities of this series are issuable only in registered form without coupons in denominations of $2,000 and integral multiples of $1,000 in excess thereof. As provided in the Indenture and subject to certain limitations therein set forth, Securities of this series are exchangeable for a like aggregate principal amount of Securities of this series and of like tenor of a different authorized denomination, as requested by the Holder surrendering the same.

In addition to the circumstances specified in Clause (2) of the last paragraph of Section 305 of the Indenture in which a Global Security of such series may be exchanged in whole or in part for Securities of such series registered, and any transfer of such Global Security in whole or in part may be registered, in the name of Persons other than the Depositary for such Global Security or a nominee thereof, the Company may, in its sole discretion, determine that such Global Security will be exchangeable for Securities registered in the name of Persons other than the Depositary or a nominee thereof and notify the Trustee of its decision.

No service charge shall be made for any such registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith.

Prior to due presentment of this Security for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name this Security is registered as the owner hereof for all purposes, whether or not this Security be overdue, and neither the Company, the Trustee nor any such agent shall be affected by notice to the contrary.

All terms used in this Security which are defined in the Indenture shall have the meanings assigned to them in the Indenture.

Registration Statement on Form S-3 (File No. 333-277039)

Ladies and Gentlemen:

We have acted as counsel to Marriott International, Inc., a Delaware corporation (the “Company”), in connection with the preparation and filing with the Securities and Exchange Commission (the “Commission”) of a prospectus supplement, dated February 20, 2024 (the “Prospectus Supplement”), filed with the Commission on February 21, 2024, pursuant to Rule 424(b) of the Securities Act of 1933, as amended (the “Securities Act”), and the offering by the Company pursuant thereto of $500,000,000 aggregate principal amount of the Company’s 4.875% Series NN Notes due 2029 (the “Series NN Notes”) and $1,000,000,000 aggregate principal amount of the Company’s 5.300% Series OO Notes due 2034 (the “Series OO Notes” and, together with the Series NN Notes, the “Notes”). In connection therewith, we have examined the registration statement on Form S-3, File No. 333-277039 (the “Registration Statement”), under the Securities Act and the prospectus included therein.

The Notes have been issued pursuant to the Indenture, dated as of November 16, 1998 (the “Base Indenture”), entered into between the Company and The Bank of New York Mellon, as successor indenture trustee to JPMorgan Chase Bank, N.A., formerly known as The Chase Manhattan Bank (the “Trustee”), as supplemented by the Officers’ Certificate pursuant to Section 301 of the Base Indenture, dated February 22, 2024, relating to the Notes (the “301 Certificate”), between the Company and the Trustee.

In arriving at the opinions expressed below, we have examined originals, or copies certified or otherwise identified to our satisfaction as being true and complete copies of the originals, of the Base Indenture, the 301 Certificate and the Notes and such other documents, corporate records, certificates of officers of the Company and of public officials and other instruments as we have deemed necessary or advisable to enable us to render these opinions. In our examination, we have assumed, without independent investigation, the genuineness of all signatures, the legal capacity and competency of all natural persons, the authenticity of all documents submitted to us as originals and the conformity to original documents of all documents submitted to us as copies. As to any facts material to these opinions, we have relied to the extent we deemed appropriate and without independent investigation upon statements and representations of officers and other representatives of the Company and others.

A. We render no opinion herein as to matters involving the laws of any jurisdiction other than the State of New York and the Delaware General Corporation Law.

This opinion is limited to the effect of the current state of the laws of the State of New York and the Delaware General Corporation Law and the facts as they currently exist. We assume no obligation to revise or supplement this opinion in the event of future changes in such laws or the interpretations thereof or such facts.
