Merck & Co., Inc.Change in Control Separation Benefits Plan



 Exhibit 10.14 
 MERCK & CO., INC. 
 CHANGE IN CONTROL SEPARATION BENEFITS PLAN

 (Effective as Amended and Restated, as of the Restatement Date) 
 ARTICLE I  
 PURPOSE 
 All capitalized terms used in this Article I are defined in Article II, below. 
 The MSD Board originally adopted the Merck & Co., Inc. Change in Control Separation Benefits Plan, effective November 23,
2004, in recognition that the possibility of a Change in Control existed and that the threat or the occurrence of a Change in Control would have resulted in significant distractions of its key executive personnel because of the uncertainties
inherent in such a situation. In addition, the MSD Board determined that it was essential and in the best interest of MSD and its stockholders at that time to retain the services of its key executive personnel in the event of a threat of a Change in
Control and to ensure their continued dedication and efforts in such event without undue concern for their personal financial and employment security. 
 In light of the Merck/Schering Plough Merger and the belief that the same Change in Control risks continue to exist, the Compensation & Benefits Committee of the MSD Board, pursuant to its
authority under the terms of the Plan, amended and restated the Plan to be effective as of the Restatement Date. Consistent with the intent of the original Plan, the amended and restated Plan, maintains the protections and benefits for key executive
personnel of MSD and its subsidiaries that were established by the original Plan. Changes reflected in the amendment and restatement include, generally, (1) an update to the definition of Change in Control to reflect that the applicable
triggering event under the terms of the Plan is a Change in Control of the Company (but not MSD), subject to the amendment provisions regarding the effectiveness of this amendment, and (2) other technical changes that have been determined to be
necessary for the proper operation of the Plan in light of the Merck/Schering-Plough Merger. 
 In addition to the MSD
Board’s Compensation & Benefits Committee action, in order to retain and acknowledge the protections and benefits provided under the Plan to key executive personnel of MSD and its subsidiaries, the Board has also adopted, effective as
of the Restatement Date, the Plan as set forth in this document.

purposes of the Plan, be considered a member of the Incumbent Board; and provided, further, however, that no individual shall be considered a member of the Incumbent Board if such individual initially assumed office as a result
of an actual or threatened solicitation of proxies or consents by or on behalf of a Person other than the Board (a “Proxy Contest”), including by reason of any agreement intended to avoid or settle any Proxy Contest; or 
 (c) The consummation of: 
 (i) A merger, consolidation or reorganization (x) with or into the Company or (y) in which securities of the Company are issued (a “Merger”), unless such Merger is a “Non-Control Transaction.” A
“Non-Control Transaction” shall mean a Merger in which:

(20%) or more of the combined voting power of the outstanding voting securities or common stock of (x) the Surviving Corporation, if there is no Parent Corporation, or (y) if there is one or more than one Parent Corporation, the
ultimate Parent Corporation; provided, however, that any Person described in clause (4) of this subsection (C) may not, immediately following the Merger, Beneficially Own more than thirty percent (30%) of the combined
voting power of the outstanding voting securities of the Surviving Corporation or the Parent Corporation, as applicable, for the Merger to constitute a Non-Control Transaction; 
 (ii) A complete liquidation or dissolution of the Company; or

Person (other than (x) a transfer to a Related Entity or (y) the distribution to the Company’s shareholders of the stock of a Related Entity or any other assets). 
 Notwithstanding the foregoing, a Change in Control shall not be deemed to occur solely because any Person (the “Subject Person”)
acquired Beneficial Ownership of more than the permitted amount of the then outstanding Shares or Voting Securities as a result of the acquisition of Shares or Voting Securities by the Company which, by reducing the number of Shares or Voting
Securities then outstanding, increases the proportional number of Shares Beneficially Owned by the Subject Persons; provided that if a Change in Control would occur (but for the operation of this sentence) as a result of the acquisition of
Shares or Voting Securities by the Company and, after such acquisition by the Company, the Subject Person becomes the Beneficial Owner of any additional Shares or Voting Securities and such Beneficial Ownership increases the percentage of the then
outstanding Shares or Voting Securities Beneficially Owned by the Subject Person, then a Change in Control shall occur.

Executive Committee Member as of the Restatement Date who is employed by an Employer shall automatically be a Participant in the Plan as of the Restatement Date. Each individual who is designated by the Chief Executive Officer as an Executive
Committee Member following the Restatement Date and who is employed by an Employer shall automatically be a Participant in the Plan as of the date of such designation. 
 (b) Other Executives. Each Other Executive as of the Restatement Date who is employed by an Employer shall automatically be a Participant in the Plan as of the Restatement Date. Each individual who
is employed by an Employer and becomes an Other Executive (whether by reason of being hired by an Employer or promoted from lower grades) shall automatically be a Participant in the Plan as of the date that he or she becomes an Other Executive.

 (c) Further Participation Restrictions. An Executive Committee Member or Other Executive must be an employee of an
Employer to be eligible to participate in the Plan. 
 3.2. Duration of Participation. 
 (a) Executive Committee Members. A Participant who is an Executive Committee Member shall cease to be a Participant in the Plan
(i) if, prior to a Change in Control (but subject to Sections 4.2 and 8.2), he or she ceases to be an Executive Committee Member, or (ii) if his or her employment with an Employer is terminated under circumstances where he or she is not
entitled to Severance Benefits under the terms of this Plan; provided, however, that, subject to Sections 4.2 and 8.2, if an Executive Committee Member ceases to be an Executive Committee Member but remains an Other Executive, he or
she shall continue to participate in the Plan as an Other Executive. 
 (b) Other Executives. A Participant who is an
Other Executive shall cease to be a Participant in the Plan (i) if, prior to a Change in Control (but subject to Sections 4.2 and 8.2), he or she ceases to be an Other Executive (other than by reason of becoming an Executive Committee Member),
or (ii) if his or her employment is terminated under circumstances where he or she is not entitled to Severance Benefits under the terms of this Plan. 
 (c) Notwithstanding anything to the contrary, in the event of a Change in Control, a Participant on or immediately prior to such Change in Control shall continue to be a Participant after the Change in
Control even if his or her employment is transferred to an Affiliate either on or following the Change in Control.

 (d) A Participant entitled to Severance Benefits under the terms of this Plan shall remain a
Participant in the Plan until the full amount of the Severance Benefits has been paid to him or her. 
 ARTICLE IV 

 SEVERANCE BENEFITS 
 4.1. Right to Severance Benefits. 
 (a) Subject to Section 4.1(b): 

a Participant shall be entitled to receive Severance Benefits from the Employer in the amount provided in Section 4.3(a) if
(i) a Change in Control has occurred and (ii) within two years thereafter, the Participant’s employment with the Employer terminates for any reason, except that, notwithstanding the foregoing provisions of this Section 4.1(a)(i),
no Severance Benefits under Section 4.3(a) shall be payable to a Participant should the Participant’s termination of employment be (A) initiated by the Employer for Cause, (B) by reason of Permanent Disability, (C) initiated
by the Participant other than for Good Reason, (D) by reason of the Participant’s death or (E) an Excluded Termination (as defined in Section 4.1(c)); and 
 a Participant shall be entitled to receive Severance Benefits from the Employer in the amount provided in Section 4.3(b) if (i) a
Change in Control has occurred and (ii) within two years thereafter, the Participant’s employment with the Employer terminates for any reason, except that, notwithstanding the foregoing provisions of this Section 4.1(a)(ii), no
Severance Benefits under Section 4.3(b) shall be payable to a Participant should the Participant’s termination of employment be (A) initiated by the Employer for Cause, (B) by reason of Permanent Disability, (C) initiated by
the Participant other than for Good Reason or (D) by reason of the Participant’s death. 
 (b) No Severance Benefits
shall be provided to a Participant unless the Participant has properly executed and delivered to the Employer a release of claims and that release of claims has become irrevocable as provided therein. Such release of claims shall not be accepted by
the Employer unless it is executed on or after the Participant’s Termination Date. The initial release of claims is attached to this Plan as Appendix A. Prior to the occurrence of a Change in Control, but subject to Section 8.2, the
release of claims may be revised by the Employer. The Employer may in any event modify the release of claims to conform it to the laws of the local jurisdiction applicable to a Participant so long as such modification does not increase the
obligations of the Participant thereunder. 
 (c) If, following a Change in Control, a Participant’s employment with the
Employer terminates in connection with the sale, divestiture or other disposition of the stock or assets of any Operating Unit (or part thereof) (a “Transaction”), such termination shall not be a termination of employment of the
Participant for purposes of the Plan, and (notwithstanding the rights provided to the Participant by Section 4.1(a)(i)) the Participant shall not be entitled to Severance Benefits as a result of such termination of employment if (i) the
Participant is offered

  

 13 








 
continued employment, or continues in employment, with the divested Operating Unit (or part thereof) or the purchaser of the stock or assets of the Operating Unit (or part thereof), or one of
their respective Affiliates (the “Post-Transaction Employer”), as the case may be, on terms and conditions that would not constitute Good Reason and (ii) the Company obtains an agreement from the acquiror of the stock or assets of the
divested Operating Unit (or part thereof), enforceable by the Participant, to provide or cause the Post-Transaction Employer to provide severance pay and benefits, if the Participant accepts the offered employment or continues in employment with the
Post-Transaction Employer or its Affiliates following the Transaction, (A) at least equal to the Severance Benefits set forth in Section 4.3(a) and (B) payable upon a termination of the Participant’s employment with the
Post-Transaction Employer and its Affiliates within such portion of the two-year period described in Section 4.1(a)(i) as is then remaining and under the same circumstances set forth in Section 4.1(a)(i). For purposes of this
Section 4.1(c), the terms “Cause” and “Good Reason” shall have the meanings ascribed to them in Sections 2.6 and 2.16 respectively, but the term “Employer” as it is used in those Sections shall be deemed to refer
to the entity employing the Participant after the Transaction, the term “Company” as used in those Sections shall be deemed to refer to such entity or, if applicable, the ultimate parent corporation of such entity, and the term
“Board” as used in those Sections shall refer to the body serving the function of a board of directors for such entity or, if applicable, the ultimate parent corporation of such entity. 
 A termination of employment described in this Section 4.1(c) is herein referred to as an “Excluded Termination.” In the
circumstances described in this Section 4.1(c), the Participant shall not be entitled to receive Severance Benefits under Section 4.3(a) of this Plan whether or not the Participant accepts the offered employment or continues in employment.
The provisions of this Section 4.1(c) do not create any entitlement to Severance Benefits from the Employer in any circumstances whatsoever and are to be construed solely as a limitation on such entitlement in the circumstances herein set
forth. 
 (d) For purposes of determining a Participant’s and the Employer’s rights and obligations under the Plan,
the transfer of employment of a Participant from the Employer or one of its subsidiaries to an Affiliate of an Employer, or from such Affiliate to the Employer or one of its subsidiaries, in each case whether before or after the Change in Control,
shall not constitute a termination of employment for purposes of the Plan; provided, however, that if such transfer takes place on or after the Change in Control, the Affiliate employing the Participant shall, with respect to that
Participant, become the Employer for all purposes under the Plan. 
 4.2. If (i) a Participant’s employment is
terminated by the Employer without Cause prior to the date of a Change in Control or (ii) an action is taken with respect to the Participant prior to the date of a Change in Control that would constitute Good Reason if taken after a Change in
Control, and the Participant reasonably demonstrates that such termination or action (A) was at the request of a third party that has indicated an intention or taken steps reasonably calculated to effect a Change in Control or
(B) otherwise arose in connection with, or in anticipation of, a Change in Control that has been threatened or proposed, such termination or action shall be deemed to have occurred after such Change in Control for purposes of the Plan, so long
as such Change in Control actually occurs. If any such termination or action occurs while an agreement is pending and the effective provisions of such agreement provide for a transaction or transactions which if consummated would constitute a Change
in Control, then such termination or action shall conclusively be presumed to have occurred in connection with a Change in Control. 
  

 14 








 4.3. Amount of Severance Benefits. 
 (a) Subject to Sections 4.3(c) through 4.3(f), if a Participant’s employment is terminated in circumstances entitling him or her to the
Severance Benefits provided in this Section 4.3(a), such Participant shall be entitled to each of the following: 
 (i)
The Employer shall pay to the Participant a Pro-Rata Bonus in a lump sum within thirty days following the Termination Date. 
 (ii) The Employer shall pay to the Participant, as severance pay and in lieu of any further Base Salary for periods subsequent to the Termination Date, an amount of cash equal to the Multiple times the sum of (A) the Base Salary and
(B) the Bonus Amount, with such severance pay to be paid in substantially equal installments not less often than monthly over a number of years equal to the Multiple, or, as to any Participant whose Multiple has been reduced pursuant to the
following proviso, over the period from the Termination Date through the date on which the Participant attains age 65; provided, however, that, for purposes of this Section 4.3(a)(2), (i) the Multiple shall be reduced if the
number of days from the Termination Date to the date on which the Participant attains age 65 is less than (x) 1,095, if the Multiple applicable to the Participant is three, (y) 730, if the Multiple applicable to the Participant is two or
(z) 547, if the Multiple applicable to the Participant is one and one-half (in each case determined without regard to the proviso) (whichever of (x), (y) or (z) is applicable to the Participant, the “Applicable Number”), and
(ii) the Multiple as so reduced shall be determined by multiplying the Multiple (determined without regard to this proviso) times a fraction, the numerator of which is the number of days from the Termination Date through the date that the
Participant attains age 65 and the denominator of which is the Applicable Number. 
 (iii) For Participants
who are U.S.-based employees eligible to participate in the Health Plan and Life Insurance Plan, for a period (the “Continuation Period”) equal to the lesser of (i) the number of full and partial years subsequent to the
Participant’s Termination Date equal to the Multiple or (ii) the period beginning on the Participant’s Termination Date and ending on his or her 65th birthday, the Employer shall continue, on behalf of the Participant and his or her
dependents and beneficiaries, the medical, dental and life insurance benefits that were being provided to the Participant and his or her dependents and beneficiaries under the Health Plan and Life Insurance Plan immediately prior to the Change in
Control or, if greater, as of the Termination Date. The cost to the Participant of such coverage and the terms and conditions of such coverage, in each case during the Continuation Period, shall be the same as those applicable to similarly situated
active U.S-based employees of the Employer during the Continuation Period. Following the Continuation Period, the Participant and his or her dependents and beneficiaries shall be eligible to elect medical and/or dental continuation coverage pursuant
to Section 601 of ERISA and Section 4980B of the Code, and the cost of such medical and dental continuation coverage shall be the same as is charged to terminated former salaried U.S.-based employees of the Employer and its subsidiaries
during such period. The obligation under this Section 4.3(a)(3) with respect to the foregoing benefits shall be reduced to the extent that the Participant obtains any such benefits pursuant to a

  

 15 








 
subsequent employer’s benefit plans, in which case the Employer may reduce or eliminate the coverage and benefits it is required to provide the Participant hereunder as long as the aggregate
coverages and benefits of the combined benefit plans are no less favorable to the Participant than the coverages and benefits required to be provided hereunder. In addition, no benefits shall be provided pursuant to this Section 4.3(a)(3) to
the extent that the Participant is entitled to the same type of benefits as a retiree of the Employer, including those eligible for treatment as a retiree under Section 4.3(b)(2), Section 4.3(b)(3) or Section 4.3(b)(4). 
 (iv) If the Participant is U.S.-based and is eligible to receive Employer-provided financial planning services as of the Termination Date,
the Employer shall, at its expense, continue to provide such financial planning services to the Participant during the calendar year in which the Termination Date occurs and during the next following calendar year. 
 (v) The Employer shall, at its expense, permit the Participant to participate in outplacement assistance services which are (1) as to
Executive Committee Members, at a level appropriate for senior management of a public company but not less than the same as at the highest level provided under the MSD Separation Benefits Plan for Nonunion Employees as in effect from time to time
and (2) as to Other Executives, the same as at the highest level provided under the MSD Separation Benefits Plan for Nonunion Employees as in effect from time to time. Outplacement benefits shall be provided in kind; cash shall not be paid in
lieu thereof, nor will cash Severance Benefits be increased if a Participant declines or does not use the outplacement benefits. 
 (b) Subject to Sections 4.3(c) through 4.3(f), if a Participant’s employment is terminated in circumstances entitling him or her to the Severance Benefits provided in this Section 4.3(b), such Participant shall be entitled to each
of the following: 
 (i) The Participant shall be entitled to the pension benefits as described in Appendix B. 
 (ii) For Participants who are U.S.-based employees eligible to participate in the Health Plan, if the Participant on his or her Termination
Date is not at least age 55 with the requisite amount of service with an Employer to satisfy the requirements to be considered a retiree under the Health Plan but would attain at least age 50 and meet the service requirements to be considered a
retiree under the Health Plan within two years following the date of the Change in Control (assuming continued employment during the entirety of such two-year period), then the Participant shall be eligible for retiree healthcare benefits under the
Health Plan on his or her Termination Date on the same terms and conditions applicable to salaried U.S.-based employees of the Employer whose employment terminated the last day of the month prior to the Participant’s Termination Date who were
treated as retirees under the Health Plan as of that date. 
 (iii) For Participants who are U.S.-based employees eligible to
participate in the Executive Health Plan who on their Termination Date are not eligible to be considered retirees under the Health Plan (including under Section 4.3(b)(2)), if the Participant on his or her Termination Date does not satisfy the
age requirement (or for Participants who are Executive Committee Members, the age or service requirements) to be considered a retiree under

  

 16 








 
the Executive Health Plan but would satisfy such requirements to be considered a retiree under the Executive Health Plan within two years following the date of the Change in Control (assuming
continued employment during the entirety of such two-year period), then the Participant shall be eligible for retiree healthcare benefits under the Executive Health Plan on his or her Termination Date on the same terms and conditions applicable to
salaried U.S.-based employees of the Employer whose employment terminated the last day of the month prior to the Participant’s Termination Date who were treated as retirees under the Executive Health Plan as of that date. 
 (iv) For Participants who are U.S.-based employees eligible to participate in the Life Insurance Plan, if the Participant on his or her
Termination Date is not either at least age 65 or at least age 55 with the requisite amount of service with an Employer to satisfy the requirements to be considered a retiree under the Life Insurance Plan but would attain at least age 65 or at least
age 50 and meet the service requirements to be considered a retiree under the Life Insurance Plan within two years following the date of the Change in Control (assuming continued employment during the entirety of such two-year period), then the
Participant shall be eligible for retiree life insurance benefits under the Life Insurance Plan on his or her Termination Date on the same terms and conditions applicable to salaried U.S.-based employees of the Employer whose employment terminated
the last day of the month prior to the Participant’s Termination Date who were treated as retirees under the Life Insurance Plan as of that date. 
 (v) The Employer may, to the extent it deems necessary or appropriate (including to comply with applicable law and to preserve grandfathered status of arrangements subject to Section 409A of the
Code), (1) cause the benefits set forth in Appendix B to be paid from the Supplemental Plan, from new arrangements or otherwise from the Employer’s general assets and (2) cause the benefits set forth in Section 4.3(b)(2),
4.3(b)(3) or 4.3(b)(4) to be provided from insured arrangements (including the Executive Health Plan), or pursuant to new arrangements, individual arrangements or otherwise. 
 (c) The payments and benefits under this Plan to a Participant are intended to constitute the exclusive payments in the nature of severance
or termination pay that shall be due to a Participant upon termination of his or her employment without Cause or for Good Reason following a Change in Control and shall be in lieu of any such other payments under any agreement, plan, practice or
policy of the Company or its subsidiaries, including the Employer,. Accordingly, if a Participant is a party to an employment, severance, termination, salary continuation or other or similar agreement with the Company or its subsidiaries, including
the Employer, or is a participant in any other severance plan, practice or policy of the Company or its subsidiaries, including the Employer, the severance pay to which the Participant is entitled under this Plan shall be reduced (but not below
zero) by the amount of severance pay to which he or she is entitled under such other agreement, plan, practice or policy; provided that the reduction set forth in this sentence shall not apply as to any other such agreement, plan, practice or
policy that contains a reduction provision substantially similar to this Section 4.3(c) so long as the reduction provision of such other agreement, plan, practice or policy is applied. The severance pay to which a Participant is otherwise
entitled shall be further reduced (but not below zero) by any cash payments to which the Participant may be entitled (x) under any federal, state or local plant-closing (or similar or analogous) law (including, without limitation, pursuant to
the U.S.

  

 17 








 
Worker Adjustment and Retraining Notification Act) or (y) under any law outside the U.S. with respect to the payment of severance, termination indemnities or other, similar payments. In
addition, cash Severance Benefits shall be reduced by the amount of short-term or long term disability benefits payable to a Participant under any plan, program or arrangement of the Company or its subsidiaries, including the Employer, in the event
that cash Severance Benefits payable hereunder cannot, by law, reduce the amount of short-term or long-term disability benefits payable to a Participant under such plan, program, or arrangement. Non-cash Severance Benefits shall be provided under
this Plan without duplication of the same or similar benefits to which a Participant may be entitled under any such agreement, plan, practice or policy. 
 (d) The Participant shall not be required to mitigate the amount of any payment provided for in this Plan by seeking other employment or otherwise and, except as provided in Section 4.3(a)(3), no
such payment shall be offset or reduced by the amount of any compensation or benefits provided to the Executive in any subsequent employment. 
 (e) The Employer’s obligation to provide the Severance Benefits to a Participant, other than those set forth in Section 4.3(b)(1), shall be conditioned on the Participant’s continued
compliance in all material respects with the restrictive covenants set forth in Section 6 of the release of claims attached hereto as Appendix A. 
 (f) Any action taken by the Company or its subsidiaries, including the Employer, that (i) forms a basis of a Participant’s termination of employment for Good Reason or (ii) is taken
following the provision of a Notice of Termination and would constitute Good Reason shall be disregarded in calculating the payments and benefits to be provided pursuant to this Section 4.3. 
 ARTICLE V  
 TERMINATION OF EMPLOYMENT 
 5.1. Written Notice Required. Any purported termination of employment,
whether by the Employer or by the Participant, shall be communicated by written Notice of Termination to the other. With respect to communications addressed to the Employer, such communication shall be sent to the Corporate Secretary of the Company
at its headquarters. 
 5.2. Termination Date. In the case of the Participant’s death, the Participant’s
Termination Date shall be his or her date of death. In all other cases, the Participant’s Termination Date shall be the date specified in the Notice of Termination subject to the following: 
 (a) If the Participant’s employment is terminated by the Employer for Cause or due to Permanent Disability, the date specified in the
Notice of Termination shall be at least 30 days from the date the Notice of Termination is given to the Participant, provided that in the case of Permanent Disability the Participant shall not have returned to the full-time performance of his or her
duties during such period of at least thirty days; and 
 (b) If the Participant terminates his or her employment for Good
Reason, the date specified in the Notice of Termination shall not be more than sixty days from the date the Notice of Termination is given to the Employer. 
  

 18 








 5.3. If the Participant terminates his or her employment for Good Reason, the Employer may,
in its discretion, require the Participant to remain employed for transition purposes for not more than thirty days after the Termination Date (such period, the “Extension Period”). If the Employer elects to continue the Participant’s
employment during the Extension Period pursuant to this Section 5.3, then (i) during the Extension Period, the Participant shall continue to receive compensation and employee benefits that are the same as in effect prior to the
commencement of the Extension Period and (ii) no act, circumstance or occurrence during the Extension Period shall affect the right of the Participant to receive the Severance Benefits determined as of the Termination Date, or if greater,
determined as of the end of the Extension Period. 
 ARTICLE VI  
 EFFECT OF SECTIONS 280G AND 4999 OF THE CODE 
 6.1.
Executive Committee Members. This Section 6.1 shall be applicable solely to Participants who are Executive Committee Members. 
 (a) Anything in this Plan to the contrary notwithstanding, in the event it shall be determined that any Payment to or in respect of a Participant would be subject to the Excise Tax, then the Participant
shall be entitled to receive an additional payment (the “Gross-Up Payment”) in an amount such that, after payment by the Participant of all taxes (and any interest or penalties imposed with respect to such taxes), including, without
limitation, any income taxes (and any interest and penalties imposed with respect thereto) and Excise Tax imposed upon the Gross-Up Payment, the Participant retains an amount of the Gross-Up Payment equal to the Excise Tax imposed upon the Payments.
The Employer’s obligation to make Gross-Up Payments under this Section 6.1 shall not be conditioned upon the Participant’s termination of employment. 
 (b) Subject to the provisions of Section 6.1(c), all determinations required to be made under this Section 6.1, including whether and when a Gross-Up Payment is required, the amount of such
Gross-Up Payment and the assumptions to be utilized in arriving at such determination, shall be made by the Company’s independent accounting firm (the “Accounting Firm”). The Accounting Firm shall provide detailed supporting
calculations both to the Employer and the Participant within thirty business days of the receipt of notice from the Participant that there has been a Payment or such earlier time as is requested by the Employer. In the event that the Accounting Firm
is serving as accountant or auditor for the individual, entity or group effecting the Change in Control, the Company shall appoint another nationally recognized accounting firm to make the determinations required hereunder (which accounting firm
shall then be referred to as the Accounting Firm hereunder). All fees and expenses of the Accounting Firm shall be borne solely by the Company. Any Gross-Up Payment, as determined pursuant to this Section 6.1, shall be paid by the Employer to
the Participant within thirty days of the receipt of the Accounting Firm’s determination. Any determination by the Accounting Firm shall be binding upon the Employer and the Participant. As a result of the uncertainty in the application of
Section 4999 of the Code at the time of the initial determination by the Accounting Firm hereunder, it is possible that Gross-Up Payments that will not have been made by the Employer should have been made (the “Underpayment”),
consistent with the calculations required to be made hereunder. In the event the Employer exhausts its remedies pursuant to

  

 19 








 
Section 6.1(c) and the Participant thereafter is required to make a payment of any Excise Tax, the Accounting Firm shall determine the amount of the Underpayment that has occurred and any
such Underpayment shall be promptly paid by the Employer to or for the benefit of the Participant. 
 (c) The Participant shall
notify the Employer in writing of any claim by the Internal Revenue Service that, if successful, would require the payment by the Employer of the Gross-Up Payment. Such notification shall be given as soon as practicable, but no later than ten
business days after the Participant is informed in writing of such claim. The Participant shall apprise the Employer of the nature of such claim and the date on which such claim is requested to be paid. The Participant shall not pay such claim prior
to the expiration of the thirty-day period following the date on which the Participant gives such notice to the Employer (or such shorter period ending on the date that any payment of taxes with respect to such claim is due). If the Employer
notifies the Participant in writing prior to the expiration of such period that the Employer desires to contest such claim, the Participant shall: 
 (i) give the Employer any information reasonably requested by the Employer relating to such claim, 
 (ii) take such action in connection with contesting such claim as the Employer shall reasonably request in writing from time to time, including, without limitation, accepting legal representation with
respect to such claim by an attorney reasonably selected by the Employer, 
 (iii) cooperate with the Employer in good faith in
order effectively to contest such claim, and 
 (iv) permit the Employer to participate in any proceedings relating to such
claim; 
 provided, however, that the Employer shall bear and pay directly all costs and expenses (including
additional interest and penalties) incurred in connection with such contest, and shall indemnify and hold the Participant harmless, on an after-tax basis, for any Excise Tax or income tax (including interest and penalties) imposed as a result of
such representation and payment of costs and expenses. Without limitation on the foregoing provisions of this Section 6.1(c), the Employer shall control all proceedings taken in connection with such contest, and, at its sole discretion, may
pursue or forego any and all administrative appeals, proceedings, hearings and conferences with the applicable taxing authority in respect of such claim and may, at its sole discretion, either pay the tax claimed to the appropriate taxing authority
on behalf of the Participant and direct the Participant to sue for a refund or contest the claim in any permissible manner, and the Participant agrees to prosecute such contest to a determination before any administrative tribunal, in a court of
initial jurisdiction and in one or more appellate courts, as the Employer shall determine; provided, however, that, if the Employer pays such claim and directs the Participant to sue for a refund, the Employer shall indemnify and hold
the Participant harmless, on an after-tax basis, from any Excise Tax or income tax (including interest or penalties) imposed with respect to such payment or with respect to any imputed income in connection with such payment; and provided,
further, that any extension of the statute of

  

 20 








 
limitations relating to payment of taxes for the taxable year of the Participant with respect to which such contested amount is claimed to be due is limited solely to such contested amount.
Furthermore, the Employer’s control of the contest shall be limited to issues with respect to which the Gross-Up Payment would be payable hereunder, and the Participant shall be entitled to settle or contest, as the case may be, any other issue
raised by the Internal Revenue Service or any other taxing authority. 
 (d) If, after the receipt by the Participant of a
Gross-Up Payment or payment by the Employer of an amount on the Participant’s behalf pursuant to Section 6.1(c), the Participant becomes entitled to receive any refund with respect to the Excise Tax to which such Gross-Up Payment relates
or with respect to such claim, the Participant shall (subject to the Employer’s complying with the requirements of Section 6.1(c), if applicable) promptly pay to the Employer the amount of such refund (together with any interest paid or
credited thereon after taxes applicable thereto). If, after payment by the Employer of an amount on the Participant’s behalf pursuant to Section 6.1(c), a determination is made that the Participant shall not be entitled to any refund with
respect to such claim and the Employer does not notify the Participant in writing of its intent to contest such denial of refund prior to the expiration of 30 days after such determination, then the amount of such payment shall offset, to the extent
thereof, the amount of Gross-Up Payment required to be paid. 
 Notwithstanding any other provision of this Section 6.1,
the Employer may, in its sole discretion, withhold and pay over to the Internal Revenue Service or any other applicable taxing authority, for the benefit of the Participant, all or any portion of any Gross-Up Payment, and the Participant hereby
consents to such withholding and payment. 
 6.2. Other Executives. This Section 6.2 shall be applicable solely to
Participants who are Other Executives. 
 (a) Anything in this Plan to the contrary notwithstanding, in the event it shall be
determined that any Payment to or in respect of a Participant would be subject to the Excise Tax, then the Payments shall be reduced (but not below zero) if and to the extent that a reduction in the Payments would result in the Participant retaining
a larger amount, on an after-tax basis (taking into account federal, state and local income taxes and the Excise Tax) than if the Participant received the entire amount of such Payments. Unless the Participant shall have given prior written notice
specifying a different order to the Employer to effectuate the foregoing, the Employer shall reduce or eliminate the Payments by first reducing or eliminating the portion of the Payments which are not payable in cash and then by reducing or
eliminating cash payments, in each case in reverse order beginning with payments or benefits which are to be paid the farthest in time from the Determination (as defined below). Any notice given by the Participant pursuant to the preceding sentence
shall take precedence over the provisions of any other plan, arrangement or agreement governing the Participant’s rights and entitlements to any benefits or compensation. 
 (b) The determination of whether the Payments shall be reduced as provided in Section 6.2(a) and the amount of such reduction shall be
made at the Employer’s expense by the Accounting Firm, which shall provide its determination (the “Determination”), together with detailed supporting calculations and documentation to the Employer and the Participant within

  

 21 








 
thirty business days after the Termination Date. If the Accounting Firm determines that no Excise Tax is payable by the Participant with respect to the Payments, it shall furnish the Participant
with an opinion reasonably acceptable to the Participant that no Excise Tax will be imposed with respect to any such payments and, absent manifest error, such Determination shall be binding, final and conclusive upon the Employer and the
Participant. 
 ARTICLE VII  
 SUCCESSORS TO EMPLOYER 
 7.1. Successors. This Plan shall bind any
successor (whether direct or indirect, by purchase, merger, consolidation or otherwise) to all or substantially all of the business and/or assets of the Company and its subsidiaries including the Employer, in the same manner and to the same extent
that the Company and its subsidiaries including the Employer would be obligated under this Plan if no succession had taken place. In the case of any transaction in which a successor would not by the foregoing provision or by operation of law be
bound by this Plan, the Company shall require such successor expressly and unconditionally to assume and agree to perform the obligations of the Company and each Employer under this Plan, in the same manner and to the same extent that the Company
and each Employer would be required to perform if no such succession had taken place. 
 7.2. Impact of Merck/Schering-Plough
Merger. 
 (a) This Plan, as amended and restated shall be assumed by Merck & Co, Inc. upon the effective time of the
Merck/Schering-Plough Merger. 
 (b) For Participant’s who were active Participants in the Plan prior to the Restatement
Date, with respect to the determination of such Participant’s right to Severance Benefits, and for all other purposes under the Plan, a “Change in Control” shall mean both a “Change in Control” defined in Section 2.7 of
the Plan and an “MSD Change in Control” defined in Section 2.26 of the Plan for the period beginning on the Restatement Date and ending on the first anniversary of the Restatement Date. 
 (c) With respect to awards of stock options, restricted stock, restricted stock units or other forms of equity awards issued pursuant to the
MSD 2007 Stock Incentive Plan (formerly known as the Merck & Co., Inc. Stock Incentive Plan) or any other incentive plans of the Company or its subsidiaries following the effective date of the Merck/Schering-Plough Merger, a “Change in
Control” shall mean a “Change in Control” defined in Section 2.7 of the Plan; provided, however, that for any stock options, restricted stock, restricted stock units or other forms of equity awards that were issued prior
to the effective date of the Merck/Schering-Plough Merger pursuant to the MSD 2007 Stock Incentive Plan and the Prior Equity Plans, a “Change in Control” shall mean both a “Change in Control” defined in Section 2.7 of the
Plan and an “MSD Change in Control” defined in Section 2.26 of the Plan for the remaining term of such outstanding awards.

 ARTICLE VIII  
 DURATION, AMENDMENT AND PLAN TERMINATION 
 8.1.
Duration. This Plan shall continue in effect until terminated in accordance with Section 8.2. If a Change in Control occurs, this Plan shall continue in full force and effect and shall not terminate or expire until after all Participants
who have become entitled to Severance Benefits hereunder shall have received such payments in full. 
 8.2. Amendment and
Termination. Prior to a Change in Control, the Plan may be amended or modified in any respect, and may be terminated, in any such case by resolution adopted by two-thirds of the Compensation and Benefits Committee of the Board; provided,
however, that no such amendment, modification or termination that would adversely affect the benefits or protections hereunder of any individual who is a Participant as of the date such amendment, modification or termination is adopted shall
be effective as it relates to such individual unless no Change in Control occurs within one year after such adoption, any such attempted amendment, modification or termination adopted within one year prior to a Change in Control being null and void
ab initio as it relates to all such individuals who were Participants prior to such adoption (it being understood, however, that, subject to Section 4.2, the hiring, termination of employment, promotion or demotion of any employee of the
Employer or transfer of an employee’s employment from an Employer to an Affiliate that is not an Employer prior to a Change in Control shall not be construed to be an amendment, modification or termination of the Plan); provided,
further, however, that the Plan may not be amended, modified or terminated, (i) at the request of a third party who has indicated an intention or taken steps to effect a Change in Control and who effectuates a Change in Control or
(ii) otherwise in connection with, or in anticipation of, a Change in Control which actually occurs, any such attempted amendment, modification or termination being null and void ab initio. Any action taken to amend, modify or
terminate the Plan which is taken after the execution of an agreement providing for a transaction or transactions which, if consummated, would constitute a Change in Control shall conclusively be presumed to have been taken in connection with a
Change in Control. From and after the occurrence of a Change in Control, the Plan may not be amended or modified in any manner that would in any way adversely affect the benefits or protections provided hereunder to any individual who is a
Participant in the Plan on the date the Change in Control occurs. The revision of the release of claims attached hereto as Appendix A shall be deemed to be a modification of the Plan for purposes of this Section 8.2. 
 8.3. Form of Amendment. The form of any amendment or termination of the Plan in accordance with Section 8.2 hereof shall be a
written instrument signed by a duly authorized officer or officers of the Company, certifying that the amendment or termination has been approved by the Compensation and Benefits Committee of the Board. 
 ARTICLE IX  
 SECTION 409A OF THE CODE 
 9.1. General. To the extent applicable, the provisions of this Plan shall be
construed in a manner consistent with Section 409A of the Code and Department of Treasury regulations and other interpretive guidance issued thereunder (collectively, “Section 409A”). If the Compensation and Benefits Committee of the
Board believes, at any time, that any benefit or

  

 23 








 
right to which a Participant is entitled under the Plan that is either subject to Section 409A or exempt from Section 409A does not so comply, the Compensation and Benefits Committee of
the Board may in its sole discretion adopt such amendments to this Plan or take such other actions that the Compensation and Benefits Committee of the Board determines are necessary or appropriate to either exempt the such benefits and rights from
Section 409A or comply with the requirements of Section 409A; provided, however, that this Section 9.1 shall not create any obligation on the part of the Compensation and Benefits Committee of the Board to adopt any such amendment or
take any other action. 
 9.2. Distributions on Account of Separation from Service. Notwithstanding anything to the
contrary, if and to the extent required to comply with Section 409A, any payment or benefit required to be paid under this Plan as part of the Participant’s Severance Benefits shall be made upon the Participant incurring a “separation
of service” within the meaning of Code Section 409A as of the Participant’s Termination Date, or day after the end of any Extension Period, as set forth in Section 5.3, if later. 
 9.3. Timing of Severance Payments. In the case where this Plan provides for the payment of an amount that constitutes nonqualified
deferred compensation under Section 409A to be made to the Participant within a designated period (e.g. within 30 days after the Termination Date) and such period begins and ends in different calendar years, the exact payment date within such
range shall, subject to Section 9.4 below, be determined by the Compensation and Benefits Committee of the Board, in its sole discretion, and the Participant shall have no right to designate the year in which the payment shall be made.

 9.4. Delay of Payments for Specified Employees. Notwithstanding anything in this Plan to the contrary, if the
Participant is deemed to be a “specified employee” for purposes of Section 409A, no Severance Benefits or other payments pursuant to, or contemplated by, this Plan shall be made to the Participant before the date that is six months
after the Participant’s “separation from service” (or, if earlier, the date of the Participant’s death) if and to the extent that such payment or benefit constitutes deferred compensation (or may be nonqualified deferred
compensation) under Section 409A. Any payment or benefit delayed by reason of the prior sentence shall be paid out or provided in a single lump sum without interest at the end of such required delay period in order to catch up to the original
payment schedule. 
 9.5. No Acceleration of Payments. No payment or benefit that is subject to Section 409A may be
accelerated, except in compliance with Section 409A and the provisions of this Plan, and no amount that is subject to Section 409A shall be paid prior to the earliest date on which it may be paid without violating Section 409A.

 9.6. Treatment of Each Installment as a Separate Payment. For purposes of applying the provisions of Section 409A
to this Plan, each separately identified amount to which a Participant is entitled under this Plan as part of the Severance Benefits shall be treated as a separate payment. In addition, to the extent permissible under Section 409A, any series
of installment payments under this Plan as part of the Severance Benefits shall be treated as a right to a series of separate payments. 
  

 24 








 9.7. Gross Up. In the event a Participant becomes entitled to a Gross-Up Payment
under Article VI, the Gross-Up Payment shall in no event be made later than December 31 of the year following the year during which the related Excise Tax is remitted to the Internal Revenue Service. 
 9.8. Continued Health Benefits. In the event that Participant receives continued health benefits pursuant to Section 4.3 of this
Plan that is not otherwise exempt under Section 409A, such expense or reimbursement shall meet the following requirements: (i) the amount of expenses eligible for reimbursement provided to the Participant during any calendar year will not
affect the amount of expenses eligible for reimbursement or in-kind benefits provided to the Participant in any other calendar year, (ii) the reimbursements for expenses for which the Participant is entitled to be reimbursed shall be made on or
before the last day of the calendar year following the calendar year in which the applicable expense is incurred, and (iii) the right to payment or reimbursement on in-kind benefits hereunder may not be liquidated or exchanged for any other
benefit. 
 9.9. Reimbursements. Notwithstanding anything in this Plan to the contrary, any payment, to the extent such
payment constitutes deferral of compensation under Section 409A, to reimburse the Participant, including but not limited to reimbursements pursuant to Section 9.8 above, shall be made no later than the end of the Participant’s taxable
year next following the Participant’s taxable year in which the Participant incurs such expense. 
 ARTICLE X 

 MISCELLANEOUS 
 10.1. Legal Fees and Expenses. The Employer shall pay all legal fees and related expenses (including the costs of experts, evidence and counsel) reasonably and in good faith incurred by a
Participant if the Participant prevails on his or her claim for relief in an action (i) by the Participant to obtain or enforce any right or benefit provided by this Plan or (ii) by the Company or the Employer to enforce post-termination
covenants against the Participant. 
 10.2. Employment Status. This Plan does not constitute a contract of employment or
impose on any Employer any obligation to retain any Participant as an employee, to change the status of any Participant’s employment as an Executive Committee Member or Other Executive (as applicable), or to change any employment policies of
any Employer. 
 10.3. Withholding of Taxes. The Employer shall withhold from any amounts payable under this Plan all
federal, state, local or other taxes that are legally required to be withheld. 
 10.4. No Effect on Other Benefits.
Severance Benefits shall not be counted as compensation for purposes of determining benefits under other benefit plans, programs, policies and agreements, except to the extent expressly provided therein or herein. 
 10.5. Validity and Severability. The invalidity or unenforceability of any provision of the Plan shall not affect the validity or
enforceability of any other provision of the Plan, which shall remain in full force and effect, and any prohibition or unenforceability in any jurisdiction shall not invalidate or render unenforceable such provision in any other jurisdiction.

  

 25 








 10.6. Settlement of Claims. The Employer’s obligation to make the
payments provided for in this Plan and otherwise to perform its obligations hereunder shall not be affected by any circumstances, including, without limitation, any set-off, counterclaim, defense, recoupment, or other right which the Employer may
have against a Participant or others. 
 10.7. Unfunded Obligation. All Severance Benefits provided under this Plan shall
constitute an unfunded obligation of the Employer. Payments shall be made, as due, from the general funds of the Employer. This Plan shall constitute solely an unsecured promise by the Employer to provide such benefits to Participants to the extent
provided herein. For avoidance of doubt, any pension, health or life insurance benefits to which a Participant may be entitled under this Plan shall be provided under other applicable employee benefit plans of the Company or the Employer. This Plan
does not provide the substantive benefits under such other employee benefit plans, and nothing in this Plan shall restrict the Company’s or Employer’s ability to amend, modify or terminate such other employee benefit plans (whether before
or after a Change in Control (but subject to Section 2.17 following a Change in Control)). 
 10.8. Governing Law.
It is intended that the Plan be an “employee welfare benefit plan” within the meaning of Section 3(1) of ERISA, and the Plan shall be administered in a manner consistent with such intent. The Plan and all rights thereunder shall be
governed and construed in accordance with ERISA and, to the extent not preempted by federal law, with the laws of the state of New Jersey, wherein venue shall lie for any dispute arising hereunder. This Plan shall also be subject to all applicable
non-U.S. laws as to Participants employed by subsidiaries of the Company located outside of the United States. Subject to the express terms and conditions set forth in the Plan, the Compensation and Benefits Committee of the Board shall have the
power from time to time to construe and interpret the Plan and to establish, amend and revoke rules and regulations for the administration of the Plan, including, but not limited to, correcting any defect or supplying any omission, or reconciling
any inconsistency in the Plan, in the manner and to the extent it shall deem necessary or advisable, including so that the Plan and the operation of the Plan complies with the Code and other applicable law, and otherwise to make the Plan fully
effective. 
 10.9. Assignment. This Plan shall inure to the benefit of and shall be enforceable by a Participant’s
personal or legal representatives, executors, administrators, successors, heirs, distributees, devisees and legatees. If a Participant should die while any amount is still payable to the Participant under this Plan had the Participant continued to
live, all such amounts, unless otherwise provided herein, shall be paid in accordance with the terms of this Plan to the Participant’s estate. A Participant’s rights under this Plan shall not otherwise be transferable or subject to lien or
attachment. 
 10.10. Enforcement. This Plan is intended to constitute an enforceable contract between the Employer and
each Participant subject to the terms hereof. 
 10.11. Restatement Date. This Plan was originally effective as of
November 23, 2004 and is Amended and Restated effective as of the date of the consummation of the Merck/Schering-Plough Merger.

 Appendix B 
 Description of Change-in-Control Benefits under the MSD Salaried Retirement Plan 
 This Appendix describes benefits under the Pension Plan and the Supplemental Plan provided to a Participant in the Plan if such Participant
signs and returns the release of claims in use under the Plan. 
 1. If a Participant’s employment is terminated in
circumstances entitling him or her to the Severance Benefits provided in Section 4.3(b) of the Plan, 
 a) For a
Participant who participates in the Pension Plan and on his or her Termination Date is not at least age 55 with at least ten years of Credited Service under the Pension Plan but would attain at least age 50 and have at least ten years of Credited
Service under the Pension Plan within two years following the date of the Change in Control (assuming continued employment during the entirety of such two-year period), then the Participant shall be deemed to be eligible for a subsidized early
retirement benefit under the Pension Plan commencing no earlier than age 55 based on his or her Credited Service under the Pension Plan accrued as of his or her Termination Date. 
 b) For a Participant who participates in the Pension Plan and on his or her Termination Date is not at least age 65 but would attain at
least age 65 within two years following the date of the Change in Control without regard to years of Credited Service (assuming continued employment during the entirety of such two-year period), then the Participant shall be deemed to be eligible
for a benefit unreduced for early commencement under the Pension Plan commencing as soon after his or her Termination Date that he or she elects to commence to receive benefits. 
 c) For a Participant who participates in the Pension Plan and on his or her Termination Date is not eligible for the “Rule of 85
Transition Benefit” (as such term is defined in the Pension Plan) but would have been eligible for the Rule of 85 Transition Benefit within two years following the date of the Change in Control (assuming continued employment during the entirety
of such two-year period), then the Participant shall be deemed to be eligible for the Rule of 85 Transition Benefit upon commencement of his or her pension benefit under the Pension Plan. 
 2. If a Participant’s employment is terminated in circumstances entitling him or her to the Severance Benefits provided in
Section 4.3(a) of the Plan, 
 a) If the Participant participates in the Supplemental Plan at any time prior to the
Termination Date, the Employer shall adjust the benefit payable thereunder (a) by adding a number of years of additional Credited Service to the Participant’s existing Credited Service as of the Termination Date equal to the Multiple,
(b) by assuming for each of the years of Credited Service added pursuant to clause (a) that the Participant’s Compensation (as such term is defined in the Pension Plan) was equal to the sum of the Participant’s Base Salary and
Bonus Amount, (c) by adding a number of years of age to the Participant thereunder equal to the Multiple and (d) then by calculating the Participant’s pension in accordance with the formula provided therein as of immediately prior to
the Change in Control or, if greater, as of the Termination Date. Anything in this Article II to the contrary notwithstanding, the application of the Multiple and any additional years of age shall not cause the Participant’s total years of
Credited Service or age to exceed the amount that would have applied to the Participant if his or her employment had continued to age 65. 
  

 32 








 3. The benefits described in Article I of this Appendix shall be payable from the Pension
Plan and, to the extent that such benefits cannot be paid from the Pension Plan, then such benefits shall be paid under the Supplemental Plan or under new arrangements or from the Employer’s general assets as provided by Section 4.3(b)(5)
of the Plan. The benefits provided under Article II shall be paid from the Supplemental Plan or under new arrangements or from the Employer’s general assets as provided by Section 4.3(b)(5) of the Plan.
