A.Restricted (Vesting) Period. The Restricted Period is the period during which this RSU Award is subject to forfeiture and is eligible to vest. The RSU Award will vest with respect to one-third of this RSUs subject to the RSU Award on each of the First, Second, and Third anniversaries of the Grant Date (each a “Vesting Date”) as shown in the box above, except as otherwise provided in Article II below. No voting rights apply to this RSU Award. No fractional shares will be issued upon settlement of the RSU Award; all calculations are subject to rounding.
B.Dividend Equivalents. During the period commencing on the Grant Date and ending on the date immediately prior to the date the RSU Awards are settled in accordance with paragraph I(C), dividend equivalents will be accrued for the holder (“you”) if and to the extent dividends are paid by the Company on Merck Common Stock. Payment of such dividends will be made in cash via local payroll, without interest or earnings, at or around the time of distribution of the shares of Common Stock in settlement of the underlying RSUs. If any portion of this RSU Award lapses, is forfeited or expires, no dividend equivalents will be credited or paid on such portion. Any payment of dividend equivalents will be reduced to the extent necessary for the Company to satisfy any tax or other withholding obligations in accordance with paragraph IV.
C.Distribution (Settlement of RSU Award). Upon vesting of the RSU Award (including as a result of the events set forth in Article II), you (or your estate, in the event the RSU Award vests pursuant to paragraph II(E)) will be issued a number of shares of Merck Common Stock equal to the number of RSUs (unless otherwise provided in paragraph II(H)) with respect to which the RSU Award has vested and the dividend equivalents that accrued on that portion; provided, however, that in the event the RSU Awards vests upon a Change in Control (as defined below) pursuant to paragraph II(H) that does not constitute a “change in control event” within the meaning of U.S. Treasury Regulations Section 1.409A-3(i)(5), the RSU Awards will instead be settled on the original Vesting Dates set forth in paragraph I(A). Any amount required to be withheld, including amounts required to satisfy Tax-Related Items, in connection with the distribution of the

RSU Award (or otherwise arising from your participation in the Plan) will be recovered from you as described in paragraph IV.
D.409A Compliance. Anything to the contrary notwithstanding, no distribution of RSUs may be made unless in compliance with Section 409A of the Code or any successor thereto. Specifically, distributions made upon or by reference to the date of an employment termination shall not be paid unless such termination constitutes a “separation from service (as defined in Section 409A)” and any such payment to a “Specified Employee” as defined in Treas. Reg. Sec. 1.409A-1(i) or any successor thereto, to the extent required by Section 409A of the Code will instead be made on the first day the seventh month following the separation from service, in the same form as they would have been made had this restriction not applied; provided further, that dividend equivalents that otherwise would have accrued will accrue during the period during which distribution is suspended.
E.Subject to Recoupment. This RSU Award will be subject to recoupment in the event of certain violations of Company policy in accordance with the Company’s Policy and Procedures for Discretionary Recoupment of Compensation for Compliance Violations, as set forth in Appendix A.1, and with the Company’s Policy and Procedures for Recoupment of Incentive-Based Compensation, applicable only for Section 16 Officers, as set forth in Appendix A.2 (as may be amended from time to time).
II.TERMINATION OF EMPLOYMENT
If your employment with the Company or, if different, the subsidiary, affiliate or joint venture (“JV”) of the Company by which you are employed (the “Employer”) is terminated during the Restricted Period described in paragraph I(A), your right to the RSU Award will be determined according to the terms in this Article II and for grantees outside the United States, also in paragraph 12 of Section A (“Nature of Grant”) of Appendix B, Part I. For avoidance of doubt, if your employment terminates on a Vesting Date not for misconduct, you will be entitled to vest in that unvested portion of the RSU Award that is scheduled to vest on that Vesting Date.
A.General Rule. If your employment is terminated during the Restricted Period for any reason other than those specified in the following paragraphs, the unvested portion of this RSU Award (and any accrued dividend equivalents) will be forfeited on the date your employment terminates. If your employment is terminated as described in this paragraph and you are later rehired by the Company or the Employer, as applicable, this grant nevertheless will expire according to this paragraph notwithstanding such rehire.
B.Involuntary Termination. If the Company determines that your employment is involuntarily terminated during the Restricted Period on or after the first anniversary of the Grant Date, the RSU Award will vest on the next subsequent Vesting Date following your employment termination with respect to a pro rata portion of your unvested RSU Award and dividend equivalents that have accrued through the corresponding Vesting Date equal to (i) the total number of RSUs subject to the RSU Award (whether or not vested), multiplied by (ii) a fraction, numerator of which is equal to the number of completed monthly periods during the period commencing on the Grant Date and ending the date employment terminates, and the denominator of which is 36, (iii) reduced by the number of RSUs that have vested pursuant to paragraph A. The remaining portion, if any, of the RSU Award and any accrued dividends will be forfeited on the date your employment terminates. An “involuntary termination” includes termination of your employment by the Company or the Employer, as applicable, as the result of a restructuring or job elimination, but excludes non-performance of your duties and the reasons listed under paragraphs C through H of this section. If your employment is terminated as described in this paragraph and you are later rehired by the Company or the Employer, as applicable, this RSU Award nevertheless will be forfeited according to this paragraph notwithstanding such rehire.
C.Sale. If your employment is terminated during the Restricted Period and the Company determines that such termination resulted from the sale of your subsidiary, affiliate, division or JV, the RSU Award will continue to vest on the following original Vesting Date(s) set forth in paragraph I(A) with respect to the following unvested portion of your RSU Award and dividend equivalents that have accrued through the corresponding Vesting Dates: if employment terminates on or after the Grant Date but before the first anniversary thereof, then one-third of your RSU Award will vest on the first Vesting Date; if employment terminates on or after the first anniversary of the Grant Date, the portion of your RSU Award that was eligible to vest on the

second and third Vesting Dates, respectively, will vest on the corresponding Vesting Dates. The remaining portion, if any, of the RSU Award that does not vest pursuant to the foregoing sentence will be forfeited on the date your employment terminates. Notwithstanding the foregoing, the Committee may determine, for purposes of this RSU Award, whether employment with an entity that is established from the Company’s spin off, split off, split up or distribution of equity securities in connection with that entity constitutes a termination of employment, and may make adjustments, if any, as it deems appropriate, and to the extent not inconsistent with the Plan, at the time of the distribution of such equity securities, in the kind and/or number of shares subject to this RSU Award. If your employment is terminated as described in this paragraph and you are later rehired by the Company or the Employer, as applicable, this RSU Award nevertheless will be forfeited according to this paragraph notwithstanding such rehire.
D.Retirement. If your employment terminates by retirement during the Restricted Period, the RSU Award will vest on the next subsequent Vesting Date following your termination with respect to a pro rata portion of your unvested RSU Award and dividend equivalents that have accrued through the corresponding Vesting Date equal to (i) the total number of RSUs subject to this RSU Award (whether or not vested), multiplied by (ii) a fraction, the numerator of which is equal to the number of completed monthly periods during the period commencing on the Grant Date and ending on the date employment terminates, and the denominator of which is 36, (iii) reduced by the number of RSUs that have vested pursuant to paragraph A. The remaining portion of the RSU Award and any accrued dividends will be forfeited on the date your employment terminates. For grantees who are employed in the U.S., “retirement” means a termination of employment after attaining the earliest of (a) age 55 with at least 10 years of service (b) such age and service that provides eligibility for subsidized retiree medical coverage or (c) age 65 without regard to years of service. For other grantees, “retirement” is determined by the Company. If your employment is terminated as described in this paragraph and you are later rehired by the Company or the Employer, as applicable, this grant nevertheless will expire according to this paragraph notwithstanding such rehire.
E.Death. If your employment terminates due to your death during the Restricted Period but prior to an employment termination contemplated under paragraphs B, C, D, G or H, the RSU Award will immediately vest with respect to any portion of this RSU Award that has not vested as of your death and dividend equivalents that have accrued though such date. If you die during the Restricted Period, but after your employment terminates for the reasons listed under paragraphs B, C, D, G or H of this section, the RSU Award will immediately vest with respect to the remaining, non-forfeited portion of this RSU Award and dividend equivalents that have accrued through the date of death.
F.Misconduct. If your employment is terminated as a result of your deliberate, willful or gross misconduct, this RSU Award and accrued dividend equivalents will be forfeited immediately upon your receipt of notice of such termination.
G.Disability. If your employment is terminated during the Restricted Period and the Company determines that such termination resulted from inability to perform the material duties of your role by reason of a physical or mental infirmity that is expected to last for at least six months or to result in your death, whether or not you are eligible for disability benefits from any applicable disability program, then the RSU Award will continue to vest on the original Vesting Dates set forth in paragraph I(A) with respect to the unvested portion of RSU Award and dividend equivalents that have accrued through the corresponding Vesting Date. If your employment is terminated as described in this paragraph and you are later rehired by the Company or the Employer, as applicable, this RSU Award nevertheless will expire according to this paragraph notwithstanding such rehire.
H.Change in Control. If this RSU Award is assumed, converted or otherwise remains outstanding in connection with a Change in Control and your employment is terminated during the Restricted Period without Cause before the second anniversary of the closing of the Change in Control, then the RSU Award will continue to vest on the original Vesting Dates set forth in paragraph I(A) with respect to the unvested portion of the RSU Award and dividend equivalents that have accrued through the corresponding Vesting Date. If this RSU Award does not remain outstanding following the Change in Control and is not converted into a successor RSU, then the RSU Award will immediately vest with respect to the portion of the RSU

Award that is unvested as of the Change in Control and dividend equivalents that have accrued though such date and, at the election of the Company, you will be entitled to receive cash for such portion of this RSU Award in an amount equal to the fair market value of the consideration paid to Merck stockholders for a share of Merck Common Stock in the Change in Control. On the second anniversary of the closing of the Change in Control, this paragraph shall expire. “Cause” and “Change in Control” are defined in the Merck & Co., Inc. Change in Control Separation Benefits Plan (excluding an MSD Change in Control).
I.Transfer of Employment. Transfer of employment between the Company, a subsidiary, affiliate, JV, JV partner or affiliate of the Company who provides services to the JV with such partner or affiliate or other entity in which the Company has determined that it has a significant business or ownership interest (together, the “Company Group”) is not considered termination of employment for purposes of this RSU Award. Such employment must be approved by the Company and contiguous with employment by the entity in the Company Group you were employed by immediately prior to the relevant transfer. The terms set out in paragraphs A through H above shall continue to apply to this RSU Award following a transfer of employment accordance with this section.
III.TRANSFERABILITY
Prior to distribution pursuant to Article I(C), the RSU Award and any interest therein shall not be sold, assigned, transferred, pledged or otherwise disposed of, alienated or encumbered, either voluntarily or involuntarily, other than by will or the laws of descent and distribution in connection with your death.
IV.TAX WITHHOLDING
Regardless of any action the Company and/or the Employer take with respect to any or all income tax, social insurance, payroll tax, payment on account or other tax-related items arising out of your participation in the Plan and legally applicable or deemed applicable to you (“Tax-Related Items”), you acknowledge that the ultimate liability for all Tax-Related Items is and remains your responsibility and may exceed the amount actually withheld by the Company and/or the Employer, if any. You further acknowledge that the Company and/or the Employer (i) make no representations or undertakings regarding the treatment of any Tax-Related Items in connection with any aspect of the RSU Award or underlying shares of Common Stock, including, but not limited to, the grant, vesting or settlement of the RSU, the subsequent sale of shares of Common Stock acquired upon the lapsing of the Restricted Period and the receipt of any dividends and/or dividend equivalents; and (ii) do not commit and are under no obligation to structure the terms of the grant or any aspect of the RSU Award to reduce or eliminate your liability for Tax-Related Items or achieve any particular tax result. Furthermore, if you have become subject to tax in more than one jurisdiction, you acknowledge that the Company and/or the Employer (or former employer, as applicable) may be required to withhold or account for Tax-Related Items in more than one jurisdiction.
Prior to the relevant taxable or tax withholding event, as applicable, you shall pay or make arrangements satisfactory to the Company and/or the Employer to satisfy any applicable withholding obligations or rights with regard to all Tax-Related Items. In this regard, you authorize the Company and/or the Employer, or their respective agents, at their discretion, to satisfy the Tax-Related Items by one or a combination of the following: (i) withholding from your wages or other cash compensation paid to you by the Company, the Employer and/or any subsidiary, affiliate or JV of the Company; or (ii) withholding from proceeds of the sale of shares of Common Stock acquired at lapsing of the Restricted Period either through a voluntary sale or through a mandatory sale arranged by the Company (on your behalf pursuant to this authorization); or (iii) withholding in shares of Common Stock to be issued upon lapsing of the Restricted Period; provided, however, that if you are a Section 16 officer of the Company under the Exchange Act, then the Company will satisfy the Tax-Related Items (other than U.S. Federal Insurance Contribution Act taxes or other Tax-Related Items which become payable in a year prior to the year in which shares of Common Stock are issued upon settlement of the RSUs) by withholding in shares of Common Stock pursuant to (iii) above, unless the use of such withholding method is problematic under applicable tax or securities law or has materially adverse accounting consequences, in which case, the obligation for Tax-Related Items may be satisfied by a one or a combination of (i) or (ii) above.

The Company may withhold or account for Tax-Related Items by considering applicable minimum statutory withholding amounts or other applicable withholding rates, including maximum applicable rates in your jurisdiction(s). In the event of over-withholding, you may receive a refund of any over-withheld amount in cash (with no entitlement to the equivalent in Common Stock), or if not refunded, you may seek a refund from the local tax authorities. In the event of under-withholding, you may be required to pay additional Tax-Related Items directly to the applicable tax authority or to the Company and/or the Employer. If the obligation for Tax-Related Items is satisfied by withholding in shares of Common Stock, for tax purposes, you will be deemed to have been issued the full number of shares of Common Stock subject to the vested RSUs, notwithstanding that a number of the shares is held back solely for the purpose of paying the Tax-Related Items due as a result of any aspect of your participation in the Plan.
You shall pay to the Company or the Employer any amount of Tax-Related Items that the Company or the Employer may be required to withhold or account for as a result of your participation in the Plan that cannot be satisfied by the means previously described in this section. The Company may refuse to issue or deliver the shares of Common Stock or the proceeds of the sale of shares if you fail to comply with your obligations in connection with the Tax-Related Items.

APPENDIX A.2
Policy and Procedures for Recoupment of
Incentive-Based Compensation
Policy
The Compensation and Management Development Committee (the “Committee”) of the Board of Directors (the “Board”) has adopted this Incentive‐Based Compensation Recoupment Policy (the “Policy”) to comply with Section 10D of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), Rule 10D‐1 promulgated thereunder (“Rule 10D‐1”) and Paragraph 303A.14 of the Listing Standards Manual of the New York Stock Exchange (“NYSE”), which require the recovery of certain Incentive‐Based Compensation in the event of an accounting restatement resulting from a material error in the consolidated financial statements of Merck & Co, Inc.

This Policy shall be administered by the Committee, which shall have express discretionary authority to interpret and construe this Policy and to make all determinations with respect to this Policy, in its sole discretion. It is intended that this Policy be interpreted in a manner that is consistent with the requirements of Section 10D of the Exchange Act and Rule 10D‐1 (or any successor statute or rule) and any other applicable rules or listing standards adopted by the U.S. Securities and Exchange Commission (the “SEC”) or NYSE. All interpretations, constructions and determinations made by the Committee under this Policy shall be final and binding on all parties. This Policy may be amended with the approval of the Committee and may be amended from time to time as necessary to reflect changes in applicable regulations and/or listing standards adopted by the SEC or NYSE. Compliance with this Policy cannot be waived.

Incentive‐Based Compensation may include awards under the Executive Incentive Plan and Performance Share Units under the Merck & Co., Inc. 2019 Stock Incentive Plan, or any successor thereto. Incentive‐Based Compensation does not include (i) base salary; (ii) “sign‐on” bonuses or other compensation granted solely due to the commencement of employment with the Company; (iii) compensation exclusively based on completion of a specific period of employment or service, without any performance condition; or (iv) compensation awarded based on subjective, non‐financial, strategic, or operational measures that are not financial reporting measures.
6.Incentive‐Based Compensation is deemed to be “received” in the fiscal period during which the financial reporting measure specified in the Incentive‐Based Compensation award is attained, even if the payment or grant of the Incentive‐Based Compensation occurs after the end of that fiscal period. Incentive‐Based Compensation in the form of an equity award that vests solely upon the basis of a financial reporting measure performance condition will be deemed to be received in the fiscal period in which it vests.
7.“Recoupment Period” is the three completed fiscal years of the Company immediately preceding the date, and any transition period of less than nine months that results from a change in the Company’s fiscal year within or immediately following those three completed fiscal years, on which the Company is required to perform an Accounting Restatement, which date is the earlier of (i) the date the Board, or a committee of the Board, concludes, or reasonably should have

concluded, that the Company is required to perform an Accounting Restatement; or (ii) a date that a court, regulator or other legallyauthorized body directs the Company to perform an Accounting Restatement.
Procedures for Recoupment of Incentive‐Based Compensation
1.In the event the Company is required to perform an Accounting Restatement, the Company shall, as promptly as reasonably possible, recoup any Incentive‐Based Compensation erroneously received by a Covered Officer during the Recoupment Period. The amount of erroneously received Incentive‐Based Compensation will be the excess of the Incentive‐Based Compensation received by the Covered Officer (whether in cash or in shares) based on the erroneous data in the original financial statements over the Incentive‐Based Compensation (whether in cash or in shares) that would have been received by the Covered Officer had it been based on the restated results, without respect to any tax liabilities incurred or paid by the Covered Officer. For Incentive‐Based Compensation based on total shareholder return or Company stock price, where the amount of erroneously awarded compensation is not subject to mathematical recalculation directly from the information in the Accounting Restatement, the amount shall be based on the Committee’s reasonable estimate of the effect of the Accounting Restatement on the applicable measure and the Committee shall maintain documentation of the determination of that reasonable estimate and provide it to the NYSE. Notwithstanding the foregoing, Incentive‐Based Compensation shall not be recouped under this Policy to the extent received by any person before the date such person served as a Covered Officer.
2.The Committee shall determine, in its sole discretion, the method of recouping any erroneously received Incentive‐Based Compensation pursuant to this Policy.
3.No recoupment shall be required if any of the following conditions are met and the Committee determines that, on such basis, recovery would be impracticable: (i) the direct expense paid to a third party to assist in enforcing this Policy would exceed the amount to be recouped, which determination must be made only after a reasonable and documented attempt by the Company to recoup the Incentive‐Based Compensation (with documentation of such reasonable attempt to recover to be provided to the NYSE); (ii) recovery would violate home country law where that law was adopted prior to November 28, 2022, which determination must be made only after the Company has obtained an opinion of home country counsel, acceptable to the NYSE, that recovery would result in such violation (with a copy of such opinion to be provided to the NYSE); or (iii) recoupment would likely cause an otherwise tax‐qualified retirement plan, under which benefits are broadly available to Company employees, to fail to meet the requirements of Section 401(a)(13) or Section 411(a) of the Internal Revenue Code of 1986, as amended, and U.S. Treasury regulations promulgated thereunder.
Indemnification Not Permitted
The Company shall not indemnify any current or former Covered Officer against the loss of erroneously awarded compensation, and shall not pay, or reimburse any Covered Officer for, premiums incurred or paid for any insurance policy to fund such Covered Officer’s potential recoupment obligations.
Disclosure of Recoupment Decisions
The Company will comply with all applicable securities laws and regulations, including SEC disclosure requirements, with respect to this Policy, and any applicable NYSE listing standard or requirements. The Company may also, but is not obligated to, provide additional disclosure beyond that required by law when the Company deems it to be appropriate and determines that such disclosure is in the best interest of the Company and its shareholders.
Effective Date
This Policy shall be effective as of December 1, 2023 (the “Effective Date”). The terms of this Policy shall apply to any Incentive‐Based Compensation that is received by Covered Officers on or after the Effective Date, even if such Incentive‐Based Compensation was approved, awarded, granted, or paid to Covered Officers prior to the Effective Date.
Miscellaneous
Nothing in this Policy shall limit or otherwise affect any of the following: 1) management’s ability to take any disciplinary action with respect to any Covered Officer; 2) the Committee’s ability to use its negative discretion with respect to any Incentive‐Based Compensation performance target at any time; or 3) the Committee’s or management’s ability to reduce the amount (in whole or in part) of a current or future bonus or other cash or non‐cash incentive compensation award to any executive or other employee for any reason as they may deem appropriate and to the extent permitted by law. Any right of recoupment under this Policy is in addition to, and not in lieu of, any other

remedies or rights of recoupment that may be available to the Company pursuant to the terms of any similar policy in any incentive plan, employment agreement, equity award agreement, or similar agreement and any other legal remedies available to the Company. This Policy shall be binding and enforceable against all Covered Officers and their beneficiaries, heirs, executors, administrators, or other legal representatives.

This Appendix, which is part of the Global Terms and Conditions for 2024 Restricted Stock Unit Grants under the Merck & Co., Inc. 2019 Incentive Stock Plan, contains additional “terms and conditions” that will apply to you if you reside outside the United States.
The terms and conditions in Part I of this Appendix apply to all grantees who reside outside the United States. The additional terms and conditions in Part II of this Appendix will also apply to you if you reside in one of the countries referenced in Part II.
The information in this Appendix is based on the laws in effect in the respective countries as of November 2023. Such laws are often complex and change frequently.

In addition, the information contained in this Appendix is general in nature and may not apply to your particular situation, and the Company is not in a position to assure you of a particular result. Accordingly, you should seek appropriate professional advice as to how the relevant laws in your country may apply to your situation.
Finally, if you are a citizen or resident of a country, or are considered a resident of a country, other than that in which you are currently working, or transfer residence and/or employment after the Grant Date, the information contained herein may not apply to you in the same manner. The Company shall, in its sole discretion, determine to what extent the terms and conditions included herein will apply under these circumstances.

Local insider trading laws and regulations may prohibit the cancellation or amendment of orders you placed before you possessed inside information. Furthermore, you could be prohibited from (i) disclosing the inside information to any third party and (ii) “tipping” third parties or causing them otherwise to buy or sell securities.

Director Notification If you are a director (including an alternate, substitute, associate or shadow director) of a Singaporean subsidiary, affiliate or JV of the Company, you are subject to certain notification requirements under the Singapore Companies Act. Among these requirements is an obligation to notify the Singapore subsidiary, affiliate or JV in writing when you receive an interest (e.g., RSU Awards, shares of Common Stock) in the Company or any related companies. In addition, you must notify the Singaporean subsidiary, affiliate or JV when you sell shares of the Company’s Common Stock or any related company (including when you sell shares of Common Stock acquired upon the expiration of the Restricted Period).

Spain | Labor Law Acknowledgment This provision supplements the “Nature of Grant” section in Part I of this Appendix B: By accepting this RSU Award, you acknowledge that you understand and agree that you consent to participation in the Plan and that you have received a copy of the Plan. You understand that the Company, in its sole discretion, has unilaterally and gratuitously decided to distribute Awards under the Plan to individuals who may be employees of the Company or its subsidiaries, affiliates or JVs throughout the world. The decision is a limited decision that is entered into upon the express assumption and condition that any grant will not economically or otherwise bind the Company or any of its subsidiaries, affiliates or JVs over and above the specific terms of the Plan on an ongoing basis. Consequently, you understand that any RSU Award is given on the assumption and condition that it shall not become a part of any employment contract (either with the Company or any of its subsidiaries, affiliates or JVs) and shall not be considered a mandatory benefit, salary for any purposes (including severance compensation) or any other right whatsoever. Further, you understand and freely accept that there is no guarantee that any benefit whatsoever shall arise from any gratuitous and discretionary Award since the future value of the RSU Award and shares of Common Stock is unknown and unpredictable. In addition, you understand that the RSU Award would not be made to you but for the assumptions and conditions referred to above; thus, you acknowledge and freely accept that should any or all of the assumptions be mistaken or should any of the conditions not be met for any reason, then any RSU Award shall be null and void. You also understand and agree that, as a condition of the grant of the RSU Award, the termination of your employment for any reason (including the reasons listed below), the RSU Award will cease vesting immediately effective on the date you are no longer providing services to the Employer or the Company or any of its subsidiaries, affiliates or JVs, unless otherwise specifically provided in the Terms. In particular, you understand and agree that the RSU Award will be forfeited without entitlement to the underlying shares of Common Stock or to any amount as indemnification in the event of a termination of your employment as described in the Terms prior to expiration of the Restricted Period by reason of, including but not limited to, resignation, retirement, disciplinary dismissal adjudged to be with cause, disciplinary dismissal adjudged or recognized to be without good cause (i.e., subject to “despido improcednte”), individual or collective dismissal on objective grounds, whether adjudged or recognized to be with or without cause, material modification of the terms of employment under Article 41 of the Workers’ Statute, relocation under Article 40 of the Workers’ Statute, Article 50 of the Workers’ Statute, unilateral withdrawal by the Employer and under Article 10.3 of the Royal Decree 1382/1985. Securities Law Information No “offer of securities to the public,” as defined under Spanish law, has taken place or will take place in the Spanish territory in connection with the grant of the RSU Award. The Plan and the Terms have not been nor will they be registered with the Comisión Nacional del Mercado de Valores, and do not constitute a public offering prospectus.

Sweden | Authorization to Withhold The following provision supplements the “Tax Withholding” section of the Terms: Without limiting the Company’s and the Employer’s authority to satisfy their withholding obligations for Tax-Related Items as set forth in the “Tax Withholding” section of the Terms, in accepting the RSU Award, you authorize the Company and/or the Employer to withhold shares of Common Stock or to sell shares of Common Stock otherwise deliverable to you upon vesting to satisfy Tax-Related Items, regardless of whether the Company and/or the Employer have an obligation to withhold such Tax-Related Items.
Switzerland | Securities Law Information The offering of participation in the Plan is considered a private offering in Switzerland; therefore, it is not subject to registration in Switzerland. Neither this document nor any other materials relating to the Plan (i) constitute a prospectus according to articles 35 et seq. of the Swiss Federal Act on Financial Services (“FinSA”), (ii) may be publicly distributed nor otherwise made publicly available in Switzerland to any person other than an employee of the Company or Employer or (iii) has been or will be filed with, approved or supervised by any Swiss reviewing body according to article 51 FinSA or any Swiss regulatory authority, including the Swiss Financial Market Supervisory Authority.
Taiwan | Securities Law Information The RSU Award and the shares of Common Stock to be issued pursuant to the Plan are available only to Eligible Employees of the Company and its subsidiaries, affiliates and JVs. The grant of the RSU Award and offer of participation in the Plan do not constitute a public offer of securities by a Taiwanese company.
Thailand | There are no country-specific provisions.
Türkiye | Securities Law Information Under Turkish law, you are not permitted to sell shares of the Company’s Common Stock in Türkiye; instead, the sale must take place outside Türkiye, which will be the case if the shares of Common Stock are sold on the New York Stock Exchange on which the shares are currently listed. You may be required to engage a Turkish financial intermediary to assist with the sale of shares of Common Stock acquired under the Plan. While you should not need to engage a Turkish financial intermediary with respect to the acquisition of such shares of Common Stock (as no consideration is paid for the RSU Award or underlying shares of Common Stock), this is less certain. In light of this uncertainty, you should consult your personal legal advisor prior to the expiration of the Restricted Period or any sale of shares of Common Stock to ensure compliance with the financial intermediary requirements.
Ukraine | Payment of Award Any RSU Award granted to you will be settled in cash only. This means that upon vesting of your RSU Award, you will receive in cash the value of the underlying shares of Common Stock at vesting, less any Tax-Related Items and broker’s fees or commissions, which will be remitted to you via local payroll. The Company reserves the right to settle the RSU Award in shares of Common Stock and to force the immediate sale of such shares of Common Stock depending on the development of applicable tax laws and regulations.

You also agree to indemnify and keep indemnified the Company and, if different, your Employer against any Tax-Related Items that they are required to pay or withhold or have paid or will pay to HMRC (or any other tax authority or any other relevant authority) on your behalf. Notwithstanding the foregoing, if you are a director or executive officer of the Company (within the meaning of Section 13(k) of the U.S. Securities Exchange Act of 1934, as amended), the amount of any income tax not collected from or paid by you within ninety (90) days of the end of the U.K. tax year in which the event giving rise to the Tax-Related Items occurs may constitute a benefit to you on which additional income tax and National Insurance contributions may be payable. You understand that you will be responsible for reporting and paying any income tax due on this additional benefit directly to HMRC under the self-assessment regime and for paying to the Company and/or the Employer (as appropriate) the amount of any employee National Insurance contributions due on this additional benefit, which may also be recovered from you through any means set forth in the “Tax Withholding” section of the Terms.

The remainder and any accrued dividend equivalents will be forfeited on the date your employment ends.

C. Salg. Hvis dit ansættelsesforhold inden for den Betingede Periode (som defineret i Vilkårene) ophører, og Selskabet vurderer, at ophøret skyldes et salg af dit datterselskab, afdeling eller joint venture, vil følgende del af din Tildeling og eventuelt optjent udbyttemodværdi blive udbetalt til dig på det tidspunkt, hvor sådan udbetaling ville være sket, hvis dit ansættelsesforhold ikke var ophørt: En tredjedel, hvis ansættelsesforholdet ophører på eller efter Tildelingstidspunktet, men før 1-årsdagen for tildelingen; og hele Tildelingen, hvis ansættelsesforholdet ophører på eller efter 1-årsdagen for tildelingen.

Hvis du dør i den begrænsede periode, men efter at dit ansættelsesforhold ophører af de årsager, der er anført i B, C, D, G eller H, vil den resterende, ikke-fortabte del af denne Award og optjente udbytteækvivalenter som er optjent indtil dødsdagen straks optjenes. | E. Death. If your employment terminates due to your death during the Restricted Period but prior to an employment termination contemplated in B, C, D, G or H, all of this Award and accrued dividend equivalents will immediately vest.

Misconduct. If your employment is terminated as a result of your deliberate, willful or gross misconduct, this Award and accrued dividend equivalents will be forfeited immediately upon your receipt of notice of such termination.

G. Uarbejdsdygtighed.

Disability. If your employment is terminated during the Restricted Period and the Company determines that such termination resulted from inability to perform the material duties of your role by reason of a physical or mental infirmity that is expected to last for at least six months or to result in your death, whether or not you are eligible for disability benefits from any applicable disability program, then this Award will continue and be distributable in accordance with its terms as if employment had continued and will be distributed at the time active employees receive distributions with respect to this Award.
H. Kontrolskifte. Hvis Selskabet eller noget moderselskabs, datterselskabs, tilknyttet parts eller joint venture af Selskabet inden for den Betingede Periode uden Berettigelse bringer dit ansættelsesforhold til ufrivillig opsigelse før den anden årsdag for gennemførelsen af et hvilket som helst Kontrolskifte (defineret som Change in Control i følgende plan: Merck & Co., Inc.

Dette afsnit bortfalder, når der er gået 2 år fra Kontrolskiftets gennemførelse. | H. Change in Control.

Change in Control Separate Benefits Plan (excluding an MSD Change in Control)), then this Award will continue in accordance with its terms as if employment had continued and will be distributed at the time active employees receive distributions with respect to this Award. If this Award does not remain outstanding following the change in control and is not converted into a successor Award, then this Award will immediately vest with respect to the portion of the Award that is unvested as of the Change in Control and dividend equivalents that have accrued through such date and, at the election of the Company, you will be entitled to receive cash for such portion of this Award in an amount equal to the fair market value of the consideration paid to Company stockholders for a share of Company Common Stock in the Change in Control. On the second anniversary of the closing of the Change in Control, this paragraph shall expire.

I. Transfer of Employment. Overførsel af ansættelsesforhold mellem Selskabet, et datterselskab, tilknyttet part, Joint Venture, Joint Venture partner eller tilknyttet part til Selskabet der yder ydelser til UV med en sådan partner eller tilknyttet part eller enhver anden enhed, som Selskabet har bestemt at Selskabet har en betydelig forretningsinteresse eller ejerandel i (samlet: " Selskabsgruppen"), anses i forhold til denne Tildeling ikke for ophør af ansættelsesforholdet. Sådan ansættelse skal godkendes af Selskabet og være sammenhængende med ansættelsen i enheden i Selskabsgruppen som du var ansat i umiddelbart inden den pågældende overførsel. Vilkårene i punkt A til H ovenfor finder fortsat anvendelse på denne Tildeling efter en overførsel af ansættelsesforhold i overensstemmelse med dette punkt. | I. Transfer of Employment. Transfer of employment between the Company, a subsidiary, affiliate, JV, JV partner or affiliate of the Company who provides services to the UV with such partner or affiliate or other entity in which the Company has determined that it has a significant business or ownership interested (together, the “Company Group”) is not considered termination of employment for purposes of this Award.

The terms set out in paragraphs A though H above shall continue to apply to this Award following a transfer of employment in accordance with this section.
6. Økonomiske aspekter ved deltagelse i Planen | 6. Financial aspects of participating in the Plan
Tildelingen har ingen umiddelbare økonomiske konsekvenser for dig. Det er først ved modning af Tildelingen og det efterfølgende salg af de modtagne ordinære aktier ved modning, at du vil kunne realisere nogen indtægt under Planen. | The grant of the Award has no immediate financial consequences for you. It is not until vesting of the Award and the subsequent sale of shares of Common Stock acquired at vesting that you may realize any income under the Plan.
Værdien af Tildelingen indgår ikke i beregningen af feriepenge, pensionsbidrag, fratrædelsesgodtgørelse, godtgørelser eller andre lovpligtige, vederlagsafhængige ydelser. | The value of the Award is not taken into account when calculating holiday allowances, pension contributions, severance pay, statutory allowance, compensation or other statutory remuneration calculated on the basis of salary.
Investering i aktier er ikke uden økonomisk risiko. Værdien af aktierne på modningstidspunkterne afhænger ikke kun af Selskabets økonomiske udvikling, men også af den generelle udvikling på aktiemarkedet. Der kan derfor ikke gives nogen garanti for, at en investering i aktier vil være overskudsgivende. | Investing in shares of Common Stock involves some financial risk. The value of the shares at the time of vesting and sale will not only be dependent on the Company's financial development, but also on the general development on the stock market. Consequently, there is no guarantee that investment in shares of Common Stock will yield a profit.
Denne erklæring berører ikke de skattemæssige konsekvenser af deltagelse i Planen, modtagelse af eventuelt udbytte eller et efterfølgende salg af de i medfør af Planen erhvervede ordinære aktier. Du anbefales at drøfte dette med din personlige økonomiske rådgiver eller skatterådgiver. | This statement does not address the tax consequences of participating in the Plan, the receipt of any dividends or the subsequent sale of any shares of Common Stock acquired under the Plan. You are encouraged to discuss this matter with your personal financial or tax advisor.
