OFFICER’S CERTIFICATE PURSUANT TO

SECTIONS 3.01 AND 3.03 OF THE INDENTURE IDENTIFIED BELOW

The undersigned officer of Exxon Mobil Corporation (the “Company”), acting pursuant to authorization contained in resolutions of the Board of Directors of the Company duly adopted on January 30, 2024, does hereby authorize, adopt and approve the following terms for a series of the Company’s debt securities designated as “Floating Rate Notes due 2074” (the “Notes”), to be issued under an indenture dated as of March 20, 2014 (the “Base Indenture”), as amended and supplemented by a first supplemental indenture dated as of June 26, 2020 (together with the Base Indenture, as further amended, supplemented or otherwise modified, the “Indenture”), each between the Company and Deutsche Bank Trust Company Americas, as trustee (the “Trustee”), which Notes have been registered for sale with the Securities and Exchange Commission pursuant to a Registration Statement on Form S-3 (No. 333-270460) under the Securities Act of 1933, as amended. Capitalized terms used but not defined herein shall have the meanings set forth in the Indenture.

I. The Notes are entitled “Floating Rate Notes due 2074.”

II. The Notes are limited in aggregate principal amount to U.S.$171,968,000, subject to (i) the Company’s right from time to time, without giving notice to or seeking the consent of the Holders of the Notes, to issue an unlimited amount of additional securities having the same ranking and the same interest rate, maturity and other terms as the Notes other than issue date, issue price and the payment of interest accruing prior to the issue date of the additional securities (such additional securities having such similar terms, together with the Notes, constituting a single series of securities under the Indenture); provided that if such additional securities are not fungible with the then-outstanding Notes for U.S. federal income tax purposes, the additional securities shall have a separate CUSIP, ISIN or other identifying number, as applicable, and (ii) Notes authenticated and delivered upon registration of transfer of, or in exchange for, or in lieu of, other Notes pursuant to the provisions of the Indenture.

III. The Notes shall mature on October 15, 2074, subject to the provisions of the Indenture and this Officer’s Certificate relating to acceleration and subject to the provisions of the Indenture and this Officer’s Certificate relating to optional redemption, repayment and shortened maturity date.

A “Business Day” means each Monday, Tuesday, Wednesday, Thursday and Friday which is not a day on which banking institutions in New York City (or other Place of Payment specified pursuant to the Indenture) are authorized or obligated by law or executive order to close.

IV. Interest on the Notes

The Notes shall bear interest at a floating rate per annum equal to Compounded SOFR (as defined herein) minus 0.450% (negative 0.450%, the “Margin”) payable quarterly in arrears on January 15, April 15, July 15 and October 15 of each year, commencing on January 15, 2025, to the persons in whose names such Notes were registered at the close of business on the immediately preceding December 31, March 31, June 30 and September 30, respectively (whether or not a Business Day).

1

Interest on the Notes shall be computed on the basis of a 360-day year and the actual number of days in the Observation Period (as defined herein). If any Interest Payment Date falls on a day that is not a Business Day, the Company shall make the interest payment on the next succeeding Business Day unless that Business Day is in the next succeeding calendar month, in which case (other than in the case of the maturity date, a redemption date or a repayment date) the Company shall make the interest payment on the immediately preceding Business Day. If an interest payment is made on the next succeeding Business Day, no interest shall accrue as a result of the delay in payment. If the maturity date, a redemption date or a repayment date of the Notes falls on a day that is not a Business Day, the payment due on such date shall be postponed to the next succeeding Business Day, and no further interest shall accrue in respect of such postponement.

On each Interest Payment Determination Date (as defined herein) relating to the applicable Interest Payment Date, the Calculation Agent shall calculate the amount of accrued interest payable on the Notes by multiplying (i) the outstanding principal amount of the Notes by (ii) the product of (a) the interest rate for the relevant interest period multiplied by (b) the quotient of the actual number of calendar days in such Observation Period divided by 360. In no event shall the interest rate on the Notes be less than zero.

The term “interest period,” with respect to the Notes, means (i) the period from and including any Interest Payment Date (or, with respect to the initial interest period only, from and including October 8, 2024) to but excluding the next succeeding Interest Payment Date, (ii) in the case of the last such period, the period from and including the Interest Payment Date immediately preceding the maturity date to but excluding the maturity date, or (iii) in the event of any redemption or repayment of the Notes, the period from and including the Interest Payment Date immediately preceding the applicable redemption or repayment date to but excluding such date.

Compounded SOFR

“Compounded SOFR” shall be determined by the Calculation Agent in accordance with the following formula (and the resulting percentage shall be rounded, if necessary, to the nearest one hundred-thousandth of a percentage point):

where:

“SOFR Index_Start” = For periods other than the initial interest period, the SOFR Index value on the preceding Interest Payment Determination Date, and, for the initial interest period, the SOFR Index value on October 4, 2024;

“SOFR Index_End” = The SOFR Index value on the Interest Payment Determination Date relating to the applicable Interest Payment Date (or, in the final interest period, relating to the maturity date, or in the case of a redemption or repayment of the Notes, relating to the applicable redemption or repayment date); and

2

“d_c” is the number of calendar days in the relevant Observation Period.

For purposes of determining Compounded SOFR:

“Interest Payment Determination Date” means the date that is two U.S. Government Securities Business Days before each Interest Payment Date (or, in the final interest period, before the maturity date or, in the case of a redemption or repayment of the Notes, before the applicable redemption or repayment date).

“Observation Period” means, in respect of each interest period, the period from and including the date that is two U.S. Government Securities Business Days preceding the first date in such interest period to but excluding the date that is two U.S. Government Securities Business Days preceding the Interest Payment Date for such interest period (or, in the final interest period, preceding the maturity date or, in the case of a redemption or repayment of the Notes, preceding the applicable redemption or repayment date).

“SOFR Index” means, with respect to any U.S. Government Securities Business Day, the SOFR Index value as published by the SOFR Administrator (as defined herein) as such index appears on the SOFR Administrator’s Website at 3:00 p.m. (New York time) on such U.S. Government Securities Business Day (the “SOFR Index Determination Time”); provided that if a SOFR Index value does not so appear as specified above at the SOFR Index Determination Time, then: (i) if a Benchmark Transition Event and its related Benchmark Replacement Date have not occurred with respect to SOFR, then Compounded SOFR shall be the rate determined pursuant to the “SOFR Index Unavailable Provisions” described below, or (ii) if a Benchmark Transition Event and its related Benchmark Replacement Date have occurred with respect to SOFR, then Compounded SOFR shall be the rate determined pursuant to the “—Effect of Benchmark Transition Event” provisions described below.

“SOFR” means the daily secured overnight financing rate as provided by the SOFR Administrator on the SOFR Administrator’s Website.

“SOFR Administrator” means the Federal Reserve Bank of New York (or a successor administrator of SOFR).

“SOFR Administrator’s Website” means the website of the Federal Reserve Bank of New York, currently at http://www.newyorkfed.org, or any successor source.

“U.S. Government Securities Business Day” means any day except for a Saturday, a Sunday or a day on which the Securities Industry and Financial Markets Association recommends that the fixed income departments of its members be closed for the entire day for purposes of trading in U.S. government securities.

Notwithstanding anything to the contrary in the documentation relating to the Notes, if the Company (or its designee) determines on or prior to the relevant Reference Time (as defined herein) that a Benchmark Transition Event and its related Benchmark Replacement Date have occurred with respect to determining Compounded SOFR, then the benchmark replacement provisions set forth below under “—Effect of Benchmark Transition Event” shall thereafter apply to all determinations of the rate of interest payable on the Notes.

3

For the avoidance of doubt, in accordance with the benchmark replacement provisions, after a Benchmark Transition Event and its related Benchmark Replacement Date have occurred, the interest rate for each interest period on the Notes shall be an annual rate equal to the sum of the Benchmark Replacement and the Margin.

SOFR Index Unavailable Provisions

If a SOFR Index_Start or SOFR Index_End is not published on the associated Interest Payment Determination Date and a Benchmark Transition Event and its related Benchmark Replacement Date have not occurred with respect to SOFR, “Compounded SOFR” means, for the applicable interest period for which such index is not available, the rate of return on a daily compounded interest investment calculated in accordance with the formula for SOFR averages, and definitions required for such formula, published on the SOFR Administrator’s Website, initially located at https://www.newyorkfed.org/markets/treasury-repo-reference-rates-information. For the purposes of this provision, references in the SOFR Averages compounding formula and related definitions to “calculation period” shall be replaced with “Observation Period” and the words “that is, 30-, 90-, or 180-calendar days” shall be removed. If SOFR does not so appear for any day “i” in the Observation Period, SOFRi for such day “i” shall be SOFR published in respect of the first preceding U.S. Government Securities Business Day for which SOFR was published on the SOFR Administrator’s Website.

Effect of Benchmark Transition Event

Benchmark Replacement. If the Company (or its designee) determines that a Benchmark Transition Event and its related Benchmark Replacement Date have occurred prior to the Reference Time in respect of any determination of the Benchmark on any date, the Benchmark Replacement shall replace the then-current Benchmark for all purposes relating to the Notes in respect of such determination on such date and all determinations on all subsequent dates.

Benchmark Replacement Conforming Changes. In connection with the implementation of a Benchmark Replacement, the Company (or its designee) shall have the right to make Benchmark Replacement Conforming Changes from time to time.

Decisions and Determinations. Any determination, decision or election that may be made by the Company (or its designee) pursuant to the benchmark replacement provisions described in this subsection “—Effect of Benchmark Transition Event,” including any determination with respect to tenor, rate or adjustment or of the occurrence or non-occurrence of an event, circumstance or date and any decision to take or refrain from taking any action or any selection, shall be conclusive and binding absent manifest error, shall be made in the Company’s (or its designee’s) sole discretion, and, notwithstanding anything to the contrary in the documentation relating to the Notes, shall become effective without consent from the Holders of the Notes or any other party.

4

Certain Defined Terms. As used herein, the following terms have the following meanings:

“Benchmark” means, initially, Compounded SOFR, as such term is defined above; provided that if a Benchmark Transition Event and its related Benchmark Replacement Date have occurred with respect to Compounded SOFR (or the published SOFR Index used in the calculation thereof) or the then-current Benchmark, then “Benchmark” means the applicable Benchmark Replacement.

“Benchmark Replacement” means the first alternative set forth in the order below that can be determined by the Company (or its designee) as of the Benchmark Replacement Date:

“Benchmark Replacement Adjustment” means the first alternative set forth in the order below that can be determined by the Company (or its designee) as of the Benchmark Replacement Date:

The Benchmark Replacement Adjustment shall not include the Margin specified herein and such Margin shall be applied to the Benchmark Replacement to determine the interest payable on the Notes.

“Benchmark Replacement Conforming Changes” means, with respect to any Benchmark Replacement, any technical, administrative or operational changes (including changes to the definitions or interpretations of “interest period,” the timing and frequency of determining rates and making payments of interest, the rounding of amounts or tenors, and other administrative matters) that the Company (or its designee) decides may be appropriate to reflect the adoption of

5

such Benchmark Replacement in a manner substantially consistent with market practice (or, if the Company (or its designee) decides that adoption of any portion of such market practice is not administratively feasible or if the Company (or its designee) determines that no market practice for use of the Benchmark Replacement exists, in such other manner as the Company (or its designee) determines is reasonably necessary or practicable).

“Benchmark Replacement Date” means the earliest to occur of the following events with respect to the then-current Benchmark:

For the avoidance of doubt, if the event giving rise to the Benchmark Replacement Date occurs on the same day as, but earlier than, the Reference Time in respect of any determination, the Benchmark Replacement Date shall be deemed to have occurred prior to the Reference Time for such determination.

“Benchmark Transition Event” means the occurrence of one or more of the following events with respect to the then-current Benchmark:

“ISDA Definitions” means the 2021 ISDA Definitions published by the International Swaps and Derivatives Association, Inc. or any successor thereto, as amended or supplemented from time to time, or any successor definitional booklet for interest rate derivatives published from time to time.

6

“ISDA Fallback Adjustment” means the spread adjustment (which may be a positive or negative value or zero) that would apply for derivatives transactions referencing the ISDA Definitions to be determined upon the occurrence of an index cessation event with respect to the Benchmark for the applicable tenor.

“ISDA Fallback Rate” means the rate that would apply for derivatives transactions referencing the ISDA Definitions to be effective upon the occurrence of an index cessation date with respect to the Benchmark for the applicable tenor excluding the applicable ISDA Fallback Adjustment.

“Reference Time” with respect to any determination of the Benchmark means (1) if the Benchmark is Compounded SOFR, the SOFR Index Determination Time, as such time is defined above, and (2) if the Benchmark is not Compounded SOFR, the time determined by the Company (or its designee) in accordance with the Benchmark Replacement Conforming Changes.

“Relevant Governmental Body” means the Federal Reserve Board and/or the Federal Reserve Bank of New York, or a committee officially endorsed or convened by the Federal Reserve Board and/or the Federal Reserve Bank of New York or any successor thereto.

“Unadjusted Benchmark Replacement” means the Benchmark Replacement excluding the Benchmark Replacement Adjustment.

All determinations made by the Calculation Agent shall, in the absence of manifest error, be conclusive for all purposes and binding on us and the Holders of the Notes. So long as Compounded SOFR is required to be determined with respect to the Notes, there will at all times be a Calculation Agent. In the event that any then acting Calculation Agent shall be unable or unwilling to act, or that such Calculation Agent shall fail duly to establish Compounded SOFR for any interest period, or the Company proposes to remove such Calculation Agent, the Company shall appoint another Calculation Agent.

V. Principal and interest on the Notes shall be payable, and the Notes may be surrendered for registration of transfer or exchange, at the office or agency of the Company maintained for that purpose, pursuant to the Indenture, which shall initially be the Corporate Trust Office of the Trustee located at 1 Columbus Circle, 17^th Floor, Mail Stop: NYC01-1710, New York, New York 10019, 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 debt.

The Company, by or through the Trustee, may at its option pay interest by United States dollar check mailed to the address of the Person entitled thereto as such address shall appear in the Security Register; provided, however, that payments in connection with Global Securities to The Depository Trust Company (“DTC”) shall be made by wire transfer of immediately available funds to the account of DTC or its nominee.

7

VI. Any or all of the Notes may be redeemed at the Company’s option at any time or from time to time, in amounts of $1,000 or any multiple of $1,000 in excess thereof, at the following redemption prices (in each case expressed as a percentage of the principal amount), if redeemed during the twelve-month periods beginning on October 15 as set forth below:

and thereafter at 100.000% of the principal amount, in each case, together with any accrued and unpaid interest thereon to but excluding the redemption date.

The Company shall send notice of any redemption at least 10 days but not more than 60 days before the redemption date to each registered Holder of the Notes to be redeemed, with such notice to be sent in accordance with the provisions of the Indenture. Once notice of redemption is sent, the Notes called for redemption shall become due and payable on the redemption date and at the applicable redemption price, plus accrued and unpaid interest to the redemption date, subject to any conditions precedent specified in such notice.

On and after the redemption date, interest shall cease to accrue on the Notes or any portion of the Notes called for redemption (unless the Company defaults in the payment of the redemption price and accrued interest). On or before the redemption date, the Company shall deposit with a paying agent or the Trustee money sufficient to pay the redemption price of and accrued interest on the Notes to be redeemed on that date. If less than all of the Notes are to be redeemed, the Notes to be redeemed shall be selected by the Trustee pro rata, by lot, or by such other method the Trustee deems to be fair and appropriate, in each case in accordance with the applicable procedures of DTC.

VII. The Notes shall be repayable at the option of a Holder of the Notes, in whole or in part, on the repayment dates and at the repayment prices (in each case expressed as a percentage of the principal amount) as set forth below:

8

and on October 15 of every second year thereafter, through and including October 15, 2071, at 100.000% of the principal amount, in each case, together with any accrued and unpaid interest thereon to but excluding the repayment date.

In order for a Note to be repaid at the option of a Holder, the Trustee must receive, at least 30 but not more than 60 days before the optional repayment date,

The repayment option may be exercised by the Holder of a Note for less than the entire principal amount of the Note but, in that event, the principal amount of the Note remaining outstanding after repayment must be in an authorized denomination.

9

VIII. If a tax event (as defined herein) occurs, the Company shall have the right to shorten the maturity of the Notes, without the consent of the Holders of the Notes,

in each case, to the extent deductible under current law, as determined in good faith by the Company’s Board of Directors, after receipt of an opinion of that counsel regarding the applicable legal standards. In that case, the amount payable on the Notes on that new maturity date shall be equal to 100.000% of the principal amount of the Notes, together with any accrued and unpaid interest thereon to but excluding that new maturity date.

If the Company elects to exercise its right to shorten the maturity of the Notes when a tax event occurs, the Company shall give notice to each Holder of the Notes not more than 60 days after the occurrence of the tax event, stating the new maturity date of the Notes. If the Notes are solely registered in the name of Cede & Co. and traded through DTC, then such notice shall be delivered to DTC, and transmitted by DTC in accordance with its practices.

“Tax event” means that the Company shall have received an opinion of nationally recognized independent tax counsel to the effect that, as a result of:

in each case, occurring on or after October 4, 2024, there is more than an insubstantial increase in the risk that interest the Company pays on the Notes is not, or will not be, deductible, in whole or in part, by the Company for U.S. federal income tax purposes.

For the avoidance of doubt, following the exercise by the Company of its right to shorten the maturity of the Notes when a tax event occurs, any references to “maturity date” herein shall refer to the new maturity date of the Notes.

IX. The Notes shall not be entitled to the benefit of any mandatory redemption or sinking fund.

X. The Notes shall be issued only in denominations of $1,000 and integral multiples thereof.

XII. Upon issuance, the Notes of each series shall be represented by one or more global Securities representing all of the aggregate principal amount of such Notes and shall be registered in the name of the nominee of DTC, which will act as depositary. DTC, or any successor depositary for the Notes permitted by the terms of the Indenture, this Officer’s Certificate and the Notes, is hereinafter referred to as the “Depositary.” Except as set forth in the Indenture, owners of beneficial interests in the Notes shall not be entitled to have Notes registered in their names, shall not receive or be entitled to receive Notes in definitive form and shall not be considered Holders of Notes under the Indenture. Notwithstanding any other provisions of the Indenture, this Officer’s Certificate or the Notes, unless and until exchanged in whole or in part for the individual Securities represented thereby, the global Security or Securities representing all or a portion of the Notes of the applicable series may not be transferred except, as provided in Section 3.05 of the Indenture, by the Depositary to another nominee of the Depositary for the Notes, or by a nominee of such Depositary to such Depositary or another nominee of such Depositary, or by such Depositary or any such nominee to a successor Depositary or nominee of such successor Depositary.

XIII. The Notes shall be defeasible pursuant to Section 4.03 of the Indenture.

XIV. The issue price of the Notes to public shall be 100.000% of the principal amount thereof.

[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 March 20, 2014 between the Company and Deutsche Bank Trust Company Americas, as Trustee (herein called the “Trustee,” which term includes any successor trustee under the Indenture), as amended and supplemented by a first supplemental indenture dated as of June 26, 2020 between the Company and the Trustee, and as further supplemented by the Officer’s Certificate setting forth the terms of the Securities dated as of the date hereof (herein collectively called the “Indenture”), to which Indenture and all indentures supplemental thereto reference is hereby made 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. This Security is one of the series designated on the face hereof, limited in aggregate principal amount to U.S.$171,968,000, subject to (i) the Company’s right from time to time, without giving notice to or seeking the consent of the Holders of the Securities, to issue an unlimited amount of additional securities in one or more series having the same ranking and the same interest rate, maturity and other terms as the Securities other than issue date, issue price and the payment of interest accruing prior to the issue date of the additional securities (such additional securities having such similar terms, together with the Securities of this series, constituting a single issue of Securities under the Indenture); provided that if such additional securities are not fungible with the then-outstanding Securities of this series for U.S. federal income tax purposes, the additional securities shall have a separate CUSIP, ISIN or other identifying number, as applicable, and (ii) Securities of this series authenticated and delivered upon registration of transfer of, or in exchange for, or in lieu of, other Securities of this series pursuant to the provisions of the Indenture. The Securities of this series are issuable as Securities only in registered form, without coupons in denominations of $1,000 or integral multiples 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 any authorized denominations, as requested by the Holder surrendering the same, upon surrender of the Security or Securities to be exchanged at any office or agency described below where Securities of this series may be presented for registration of transfer.

Compounded SOFR

“Compounded SOFR” shall be determined by the Calculation Agent in accordance with the following formula (and the resulting percentage shall be rounded, if necessary, to the nearest one hundred-thousandth of a percentage point):

where:

“SOFR Index_Start” = For periods other than the initial interest period, the SOFR Index value on the preceding Interest Payment Determination Date, and, for the initial interest period, the SOFR Index value on October 4, 2024;

A-6

“SOFR Index_End” = The SOFR Index value on the Interest Payment Determination Date relating to the applicable Interest Payment Date (or, in the final interest period, relating to the maturity date, or in the case of a redemption or repayment of the Securities of this series, relating to the applicable redemption or repayment date); and

“d_c” is the number of calendar days in the relevant Observation Period.

For purposes of determining Compounded SOFR:
