COOPERATION AGREEMENT

This Cooperation Agreement (this “Agreement”) dated February 3, 2017, is by and among the persons and entities listed on Schedule A (collectively, the “Àshe Group”, and individually a “member” of the Àshe Group), Allison Transmission Holdings, Inc. (the “Company”) and William R. Harker, in his individual capacity and as a member of the Àshe Group (the “Àshe Designee”).

WHEREAS, the Àshe Group currently beneficially owns 10,031,115 shares of the common stock, par value $0.01 per share, of the Company (the “Common Stock”), which represents approximately 6.07% of the issued and outstanding shares of Common Stock.

WHEREAS, the Nominating and Governance Committee of the Board (the “Nominating Committee”) and the Company’s Board of Directors (the “Board”) have considered the qualifications of the Àshe Designee and conducted such review as they have deemed appropriate.

WHEREAS, the Board has determined that it is in the best interests of the Company to agree to the appointment of the Àshe Designee on the terms and subject to the conditions set forth in this Agreement.

NOW, THEREFORE, In consideration of and reliance upon the mutual covenants and agreements contained herein, and for other good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged, the parties hereto agree as follows:

1. Board Nomination.

(a) If (i) either (1) a person affiliated with ValueAct Capital Management, L.P. or its affiliates (“ValueAct”) (currently Gregory P. Spivy) or (2) a person affiliated with Longview Asset Management, LLC or its affiliates (“Longview”) (currently James A. Star), ceases to serve as a member of the Board for any reason in a circumstance, in either case, in which a replacement director that is a person affiliated with such stockholder is not promptly appointed, the Board shall promptly appoint the Àshe Designee to serve as a director on the Board and thereafter nominate or renominate, as applicable, the Ashe Designee for election to the Board at the Company’s 2017 and 2018 annual meeting of stockholders; (ii) the Board fails to nominate both a director who is a person affiliated with ValueAct and a person affiliated with Longview for election to the Board at the Company’s 2017 or 2018 annual meeting of stockholders, the Board shall nominate or renominate, as applicable, the Àshe Designee for election as a director at the Company’s 2017 and 2018 annual meetings of stockholders; or (iii) either ValueAct or Longview ceases to beneficially own at least 5% of the Company’s outstanding Common Stock, the Board shall nominate or renominate, as applicable, the Àshe Designee for election as a director at the Company’s 2017 and 2018 annual meetings of stockholders; provided that, in the case of any of the foregoing clauses (i) to (iii) of this Section 1(a), (x) the Company shall have completed, to its satisfaction, a customary background check on the Àshe Designee, (y) the Board does not conclude in good faith, after consultation with outside legal counsel, that such appointment would constitute a breach of the directors’ fiduciary duties (it being acknowledged that to the extent the Board makes such a determination the Company shall promptly inform the Ashe Group of such determination and a replacement candidate shall be selected pursuant to Section 1(e) below), and (z) under no circumstances shall the Board be obligated to appoint, nominate or renominate more than one Àshe Designee to the Board pursuant to this Section 1(a).

(b) As a condition to the Àshe Designee’s appointment to the Board, the Àshe Group, including the Àshe Designee, agrees to provide to the Company information required to be or customarily disclosed for directors, candidates for directors, and their affiliates and representatives in a proxy statement or other filings under applicable law or stock exchange rules or listing standards, information in connection with assessing eligibility, independence and other criteria applicable to directors or satisfying compliance and legal obligations, and such other information as reasonably requested by the Company from time to time with respect to the Àshe Group and the Àshe Designee.

1

(c) The Àshe Designee agrees that, at all times while serving as a member of the Board, he will (i) meet all director independence and other standards of the Company, the New York Stock Exchange and the Securities and Exchange Commission (“SEC”) and applicable provisions of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and the rules and regulations promulgated thereunder, including Rule 10A-3; and (ii) be qualified to serve as a director under the Delaware General Corporation Law (the “DGCL”) (clauses (i) and (ii), the “Conditions”). The Àshe Designee will promptly advise the Nominating Committee if he ceases to satisfy any of the Conditions.

(d) At all times while serving as a member of the Board, the Àshe Designee shall comply with all policies, procedures, processes, codes, rules, standards and guidelines applicable to Board members, including the Company’s Code of Business Conduct, Insider Trading Policy, Executive Stock Ownership Policy as in effect on the date hereof, and Corporate Governance Guidelines, and (except as permitted by the Confidentiality Agreement (as defined in Section 7 below)) preserve the confidentiality of Company business and information, including discussions or matters considered in meetings of the Board or Board committees to the extent not disclosed publicly by the Company.

(e) So long as the Àshe Group collectively beneficially owns, in the aggregate, at least 5% of the outstanding Common Stock, if, during the Covered Period, a vacancy on the Board is created as a result of the Àshe Designee’s ceasing to serve as a director for any reason then the Àshe Group and the Company (acting through the Board) shall work together in good faith to fill such vacancy or replace such nominee with an individual who (A) meets the Conditions, (B) meets the historical standards and criteria applied by the Company in nominating and appointing directors, and (C) is otherwise mutually acceptable (in each of their sole discretion) to the Àshe Group and the Company, and thereafter such individual shall serve and/or be nominated as the “Àshe Designee” under this Agreement.

(f) The Company’s obligations hereunder shall terminate immediately, and the Àshe Designee shall promptly offer to resign from the Board, and any committee of the Board on which he then sits (and, if requested by the Company, promptly deliver his written resignation to the Board (which shall provide for his immediate resignation) it being understood that it shall be in the Board’s sole discretion whether to accept or reject such resignation) if: (i) members of the Àshe Group, collectively, cease to beneficially own at least 5% of the Company’s outstanding Common Stock; (ii) the Àshe Designee ceases to satisfy the conditions set forth in clauses (c)-(d) above; (iii) a member of the Àshe Group, including the Àshe Designee, otherwise ceases to comply or breaches any of the terms of this Agreement or the Confidentiality Agreement in any material respect and such breach continues after notice from the Company and a 10 day opportunity to cure; or (iv) the employment of the Àshe Designee with the Àshe Group is terminated for any reason. The Àshe Group agrees to cause the Àshe Designee to resign from the Board if the Àshe Designee fails to resign if and when requested pursuant to this Section 1(f). Notwithstanding the foregoing, in the event of the occurrence of an event set forth in subsection (ii) or (iv) above, the provisions of Section 1(e) must be complied with and the Company’s obligations hereunder shall not terminate.

(g) The percentage thresholds set forth in clauses (e) and (f) above shall not be deemed unsatisfied to the extent a failure to maintain the specified ownership thresholds is the result of share issuances or similar Company actions that increase the number of outstanding shares of Common Stock.

2. Standstill.

(a) Each member of the Àshe Group agrees that, during the Covered Period, (unless specifically requested in writing by the Company, acting through a resolution of a majority of the Company’s directors not including the Àshe Designee), it shall not, and shall cause each of its Affiliates or Associates (as such terms are defined in Rule 12b-2 promulgated by the SEC under the Exchange Act) (collectively and individually, the “Àshe Affiliates”), not to, directly or indirectly, in any manner, alone or in concert with others:

2

(ii) form, join, encourage, influence, advise or in any way participate in any Group (as such term is defined in Section 13(d)(3) of the Exchange Act) with any persons who are not Àshe Affiliates with respect to any securities of the Company or otherwise in any manner agree, attempt, seek or propose to deposit any securities of the Company in any voting trust or similar arrangement, or subject any securities of the Company to any arrangement or agreement with respect to the voting thereof, except as expressly set forth in this Agreement;

(iv) sell, offer or agree to sell directly or indirectly, through swap or hedging transactions or otherwise, the securities of the Company or any rights decoupled from the underlying securities of the Company held by the Àshe Group or any Àshe Affiliate to any person or entity not a (A) party to this Agreement, (B) member of the Board, (C) officer of the Company or (D) Àshe Affiliate (any person or entity not set forth in clauses (A)-(D) shall be referred to as a “Third Party”), that would knowingly result in such Third Party, together with its affiliates and associates, owning, controlling or otherwise having any beneficial or other ownership interest in the aggregate of more than 4.9% of the shares of Common Stock outstanding at such time, except in a transaction approved by the Board;

(v) effect or seek to effect, offer or propose to effect, cause or participate in, or in any way assist or facilitate any other person to effect or seek, offer or propose to effect or participate in, any tender or exchange offer, merger, consolidation, acquisition, scheme, arrangement, business combination, recapitalization, reorganization, sale or acquisition of material assets, liquidation, dissolution or other extraordinary transaction involving the Company or any of its subsidiaries or joint ventures or any of their respective securities (each, an “Extraordinary Transaction”), or make any public statement with respect to an Extraordinary Transaction; provided, however, that this clause shall not preclude the tender by the Àshe Group or a Àshe Affiliate of any securities of the Company into any tender or exchange offer or vote by the Àshe Group or a Àshe Affiliate of any securities of the Company with respect to any Extraordinary Transaction;

(vi) engage in any short sale or any purchase, sale or grant of any option, warrant, convertible security, stock appreciation right, or other similar right (including, without limitation, any put or call option or “swap” transaction) with respect to any security (other than a broad-based market basket or index) that includes, relates to or derives any significant part of its value from a decline in the market price or value of the securities of the Company;

(xii) request, directly or indirectly, any amendment or waiver of the foregoing.

The foregoing provisions of this Section 2(a) shall not be deemed to prohibit the Àshe Group or its directors, officers, partners, employees, members or agents (acting in such capacity) (“Representatives”) from communicating privately with the Company’s directors, officers or advisors so long as such communications are not intended to, and would not reasonably be expected to, require any public disclosure of such communications.

(b) Each member of the Àshe Group shall, during the Covered Period, cause all shares of Common Stock beneficially owned, directly or indirectly, by it, or by any Àshe Affiliate, to be present for quorum purposes and to be voted, at the Company’s annual and special stockholder meetings and at any adjournments or postponements thereof, and further agrees that at all such meetings they shall vote in favor of (i) all directors nominated by the Board for election at such meeting and (ii) in accordance with the Board’s recommendation with respect to any proposals that may be the subject of stockholder action at such meeting, other than with respect to (a) an Extraordinary Transaction, (b) any proposed issuance of Company securities or (c) any proposal to implement any takeover defense measures or any other proposal that would diminish or otherwise impair in any material respect the rights of Company shareholders.

(c) The Àshe Group acknowledges that the Àshe Designee shall have all of the rights and obligations, including fiduciary duties to the Company and its stockholders, of a director under applicable law and the Company’s organizational documents while the Àshe Designee is serving on the Board.

10. Miscellaneous. The parties agree that irreparable damage would occur in the event any of the provisions of this Agreement were not performed in accordance with the terms hereof and that such damage would not be adequately compensable in monetary damages. Accordingly, the parties hereto shall be entitled to an injunction or injunctions to prevent breaches of this Agreement, to enforce specifically the terms and provisions of this Agreement exclusively in the Court of Chancery or other federal or state courts of the State of Delaware and to require the resignation of the Àshe Designee from the Board commencing on the date that is 10 days following the date that the Àshe Designee and/or the Àshe Group materially breaches its obligations under this Agreement, provided, that, such breach has not been cured prior to the expiration of such 10-day period, in addition to any other remedies at law or in equity, and each party agrees it will not take any action, directly or indirectly, in opposition to another party seeking relief. Each of the parties hereto agrees to waive any bonding requirement under any applicable law, in the case any other party seeks to enforce the terms by way of equitable relief. Furthermore, each of the parties hereto (a) consents to submit itself to the personal jurisdiction of the Court of Chancery or other federal or state courts of the State of Delaware in the event any dispute arises out of this Agreement or the transactions contemplated by this Agreement, (b) agrees that it shall not attempt to deny or defeat such personal jurisdiction by motion or other request for leave from any such court, (c) agrees that it shall not bring any action relating to this Agreement or the transactions contemplated by this Agreement in any court other than the Court of Chancery or other federal or state courts of the State of Delaware, and each of the parties irrevocably waives the right to trial by jury, and (d) each of the parties irrevocably consents to service of process by a reputable overnight mail delivery service, signature requested, to the address set forth in Section 13 of this Agreement or as otherwise provided by applicable law.

This Agreement may be amended only by an agreement in writing executed by the parties hereto, and no waiver of compliance with any provision or condition of this Agreement and no consent provided for in this Agreement shall be effective unless evidenced by a written instrument executed by the party against whom such waiver or consent is to be effective. No failure or delay by a party in exercising any right, power or privilege hereunder shall operate as a waiver thereof, nor shall any single or partial exercise thereof preclude any other or further exercise thereof or the exercise of any right, power or privilege hereunder.

All notices, consents, requests, instructions, approvals and other communications provided for herein and all legal process in regard hereto shall be in writing and shall be deemed validly given, made or served, when delivered in person or sent by overnight courier, when actually received during normal business hours at the address specified in this subsection:

14. Severability. If at any time subsequent to the date hereof, any provision of this Agreement shall be held by any court of competent jurisdiction to be illegal, void or unenforceable, such provision shall be of no force and effect, but the illegality or unenforceability of such provision shall have no effect upon the legality or enforceability of any other provision of this Agreement.

15. Counterparts. This Agreement may be executed in two or more counterparts either manually or by electronic or digital signature (including by facsimile or electronic mail transmission), each of which shall be deemed to be an original and all of which together shall constitute a single binding agreement on the parties, notwithstanding that not all parties are signatories to the same counterpart.

16. No Third Party Beneficiaries; Assignment. This Agreement is solely for the benefit of the parties hereto and is not binding upon or enforceable by any other persons. No party to this Agreement may assign its rights or delegate its obligations under this Agreement, whether by operation of law or otherwise, and any assignment in contravention hereof shall be null and void. Nothing in this Agreement, whether express or implied, is intended to or shall confer any rights, benefits or remedies under or by reason of this Agreement on any persons other than the parties hereto, nor is anything in this Agreement intended to relieve or discharge the obligation or liability of any third persons to any party.
