BOOKING HOLDINGS INC.,
a corporation duly organized and existing under the laws of the State of Delaware (herein called the “Company”, which
term includes any successor Person under the Indenture referred to on the reverse hereof), for value received, hereby promises
to pay to Cede & Co. or registered assigns, the principal sum as set forth in the attached Schedule of Increases and 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, semi-annually in arrears on April 13 and October 13 of each year, in U.S. dollars,
commencing on October 13, 2020, on said principal sum at said office or agency, in like coin or currency, at the rate of 4.500%
per annum. Interest on the Notes (as defined on the reverse hereof) will accrue from the most recent date from which interest has
been paid, or if no interest has been paid, from April 13, 2020, until payment of said principal sum has been made or duly provided
for. The interest so payable on April 13 and October 13 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 April 1 and
October 1, preceding such April 13 and October 13, respectively, 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 thirty days preceding such special record date or may be
paid in any other lawful manner.  Interest on this Note will be calculated on the basis of a 360 day year comprised of
twelve 30 day months.


 


If any interest payment
date or the maturity date falls on a day that is not a business day, the required payment will be made on the next succeeding business
day and no interest on such payment will accrue in respect of the delay. The term ‘‘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 are authorized
or required by law or executive order to close.

[REVERSE OF NOTE]


 


1.            Notes.


 


This Note is one of a duly authorized issue
of Senior Notes of the Company (herein called the “Notes”), issued and to be issued in one or more series under
an Officers’ Certificate of the Company, dated as of April 13, 2020 (the “Officers’ Certificate”),
pursuant to the Indenture dated as of August 8, 2017 (the “Base Indenture” and, together with the Officer’s
Certificate, the “Indenture”) between the Company and U.S. Bank National Association, 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 and of the terms upon which the Notes are, and are to be, authenticated and delivered. This Note is
one of the series designated on the face hereof as “4.500% Senior Notes due 2027,” issued in an initial aggregate principal
amount of $750,000,000. The Notes will be issued only in minimum denominations of $2,000 and integral multiples of $1,000 in excess
thereof. All terms used in this Note which are defined in the Indenture shall have the meanings assigned to them in the Indenture.


 


2.            No Sinking Fund.


 


The Notes will not be entitled to the benefit
of any sinking fund.


 


3.            Optional Redemption.


 


(a) At the Company’s option, the Notes
may be redeemed in whole or in part on or after February 13, 2027 (the “Par Call Date”), at 100% of the principal
amount of the Notes to be redeemed, plus accrued and unpaid interest thereon, if any, to, but excluding, the date of redemption.


 


(b) At the Company’s option, the Notes
may be redeemed prior to the Par Call Date, in whole or in part, at any time. If the Company elects to redeem the Notes prior to
the Par Call Date, the Company will pay a redemption price equal to the greater of the following amounts, plus, in each case, accrued
and unpaid interest thereon, if any, to, but excluding, the redemption date: (1) 100% of the aggregate principal amount of the
Notes to be redeemed and (2) as determined by a Quotation Agent, the sum of the present values of the remaining scheduled payments
of principal and interest thereon redeemed that would have been payable in respect of such Notes calculated as if the maturity
date of such Notes was the Par Call Date, not including any portion of the payments of interest accrued to, but excluding, the
date of redemption, discounted to such redemption date on a semi-annual basis (assuming a 360 day year consisting of twelve 30
day months) at the Adjusted Treasury Rate, plus 50 basis points. Neither the Trustee nor the Paying Agent shall have any responsibility
for calculating the redemption price.


 


“Adjusted Treasury Rate”
means, with respect to any redemption date, the rate per annum equal to the semi-annual equivalent yield to maturity of the Comparable
Treasury Issue, assuming a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to
the Comparable Treasury Price for such redemption date.


 






     


     


    

 


“Comparable Treasury Issue”
means, with respect to the Notes, the United States Treasury security selected by the Quotation Agent as having an actual or interpolated
maturity comparable to the remaining term of the Notes (assuming the Notes matured on February 13, 2027) that would be utilized,
at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate debt securities
of comparable maturity to the remaining term of the Notes (assuming the Notes matured on February 13, 2027).


 


“Comparable Treasury Price”
means, with respect to any redemption date, the average of the Reference Treasury Dealer Quotations for such redemption date.


 


“Quotation Agent” means
the Reference Treasury Dealer appointed as such agent by the Company.


 


“Reference Treasury Dealer Quotations”
means, with respect to any Reference Treasury Dealer and any redemption date, the average, as determined by the Quotation Agent,
of the bid and asked prices for the applicable Comparable Treasury Issue (expressed in each case as a percentage of its principal
amount) quoted in writing to the Quotation Agent by that Reference Treasury Dealer at 5:00 p.m., New York City time, on the third
business day preceding that redemption date.


 


“Reference Treasury Dealers”
means each of (i) BofA Securities, Inc., Deutsche Bank Securities Inc., Goldman Sachs & Co. LLC and J.P. Morgan Securities
LLC or an Affiliate or successor thereof, unless any such entity ceases to be a primary U.S. Government securities dealer in the
United States (a “Primary Treasury Dealer”), in which case the Company shall substitute another Primary Treasury
Dealer; and (ii) any two other Primary Treasury Dealers selected by the Company.


 


4.            Selection and Notice
of Redemption.


 


(a)           If
less than all of the Notes are to be redeemed, in the case of certificated Notes, the Trustee will select Notes for redemption
pro rata or by lot, or by a method that complies with applicable depositary requirements. In the case of global Notes, the
Depositary in coordination with the Paying Agent may select global Notes for redemption pursuant to its applicable procedures.
The Trustee, in the case of certificated Notes shall select Notes and portions of Notes in amounts of $2,000 and integral multiples
of $1,000 in excess thereof. The Depositary, in connection with the Paying Agent, in the case of global Notes, shall select Notes
and portions of Notes in amounts of $2,000 and integral multiples of $1,000 in excess thereof.


 


(b)           Notices
of redemption will be sent at least 30 but not more than 60 days before the redemption date to each Holder of Notes to be redeemed
at its registered address. Notices of redemption may be conditional.


 






     


     


    

 


5.            Acceleration Upon
Event of Default.


 


(a) If an Event of Default occurs and is
continuing, the Trustee by notice to the Company, or the Holders of at least 25% in principal amount of the then outstanding Notes
by written notice to the Company and the Trustee, may, and the Trustee at the written request of such holders shall, declare all
the Notes to be due and payable immediately. Notwithstanding the foregoing, in the case of an Event of Default arising from certain
events of bankruptcy or insolvency with respect to the Company, all outstanding Notes will become due and payable immediately without
further action or notice. Holders may not enforce the Indenture or the Notes except as provided in the Indenture. Subject to certain
limitations, Holders of a majority in principal amount of the then outstanding Notes may direct the Trustee in its exercise of
any trust or power.


 


(b) The Holders of a majority in aggregate
principal amount of the Notes then outstanding by notice to the Trustee may on behalf of the Holders of all Notes waive any existing
Default and its consequences under the Indenture except (i) a continuing Default in the payment of interest on, or the principal
of, the Notes (provided, however, that the Holders of a majority in aggregate principal amount of the then outstanding
Notes may rescind an acceleration and its consequences, including any related payment default that resulted from such acceleration),
(ii) a Default arising from the failure to redeem the Notes when required pursuant to the Indenture or (iii) a Default in respect
of a provision that under Section 9.02 of the Indenture cannot be amended without the consent of each Holder of the Notes.


 


(c) The Indenture provides that if a Default
occurs and is continuing and if it is actually known to a Responsible Officer of the Trustee, the Trustee shall mail to each Holder
notice of the Default within 90 days after it occurs. Except in the case of a Default in the payment of principal of or interest
on any Note, the Trustee may withhold the notice if and so long as it in good faith determines that withholding the notice is in
the interests of Holders. In addition, the Company is required to deliver to the Trustee, within 120 days after the end of each
Fiscal Year, an Officers’ Certificate stating that in the course of the performance by the signers of their duties as Officers
of the Company they would normally have knowledge of any Default and whether or not the signers know of any Default that occurred
during such period. The Company is also required to deliver to the Trustee, within 30 days after the Company first gains knowledge
of the occurrence thereof, written notice in the form of an Officers’ Certificate of any event which with the giving of notice
or the lapse of time would become an Event of Default, its status and what action the Company is taking or proposes to take with
respect thereto (provided that, solely with respect to an Event of Default arising from certain events of bankruptcy or
insolvency, no such status or description of action is required).


 


6.            Amendment and Modification.


 


The Indenture permits, with certain exceptions
as therein provided, the amendment of the Notes or the Indenture and the modification of the rights and obligations of the Company
and the rights of the Holders under the Indenture at any time by the Company and the Trustee with the consent of the Holders of
not less than a majority in principal amount of the Securities of all Series under the Indenture then outstanding and affected
by such amendment, voting as a single class.


 






     


     


    

 


7.            No Impairment of
Obligation to Pay or Right to Convert.


 


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, premium, if any, and interest on this Note at the times, places and rate, and in the coin or currency,
herein prescribed.


 


8.            Transfer and Exchange.


 


As provided in the Indenture and subject
to certain limitations set forth therein, the Notes shall be transferable only upon the surrender of a Note for registration of
transfer. When a Note is presented to the Registrar with a request to register a transfer, the Registrar will register the transfer
as requested if the requirements of the Indenture are satisfied. When Notes are presented to the Registrar with a request to exchange
them for an equal principal amount of Notes of other denominations, the Registrar shall make the exchange as requested if the requirements
of the Indenture are met. To permit registration of transfers and exchanges, the Company will execute and the Trustee will authenticate
Notes at the Registrar’s request.


 


9.            No Service Charge.


 


No service charge shall be made for any
such registration of transfer or exchange, but the Company may require payment by the Holder of a sum sufficient to pay all taxes,
assessments or other governmental charges in connection therewith.


 


10.          Treatment as Owner.


 


The registered Holder of a Note will be
treated as the owner of it for all purposes.


 


11.          Payment of Interest.


 


For Notes in definitive form, interest on
such Notes will be payable (i) to Holders holding an aggregate principal amount of Notes of $1.0 million or less, by check mailed
to the Holders of those Notes and (ii) to Holders holding an aggregate principal amount of Notes of more than $1.0 million, 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, in writing, the Registrar to the contrary.


 


The Company shall pay the principal of and
interest on Notes in global form registered in the name of or held by Cede & Co. or its respective nominees in immediately
available funds to Cede & Co. or its respective nominees, as the case may be, as the registered Holder of such global Notes.


 






     


     


    

 


12.          No Liability.


 


No past, present or future director, officer,
employee, incorporator or stockholder of the Company, as such, shall have any liability (except in the case of bad faith or willful
misconduct) for any obligations of the Company under the Notes or the Indenture or for any claim based on, in respect of, or by
reason of, such obligations or their creation. Each Holder by accepting a Note waives and releases all such liability. Such waiver
and release are part of the consideration for the issuance of the Notes.


 


13.          Governing Law.


 


THE INDENTURE AND THE NOTES SHALL BE GOVERNED
BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK BUT WITHOUT GIVING EFFECT TO APPLICABLE PRINCIPLES OF CONFLICTS
OF LAW TO THE EXTENT THAT THE APPLICATION OF THE LAWS OF ANOTHER JURISDICTION WOULD BE REQUIRED THEREBY.
