which the Board of Directors determines to expand the Board of Directors to add an additional Independent Director as contemplated by Section 2.1(a), one (1) individual nominated by Board of Directors who qualifies as an Independent
Director; and 
 (vi) at such time as the Company ceases to be a Controlled Company, such additional number of
Directors as is determined by the Board of Directors, which additional Directors shall be nominated and elected as provided in the Second Amended and Restated Certificate of Incorporation of the Company (as in effect on the Effective Date, and as
thereafter further amended from time to time, the “Certificate of Incorporation”) and the Bylaws. 
 (c) The
Chairman of the Board will be elected by a majority of the members of the Board of Directors, with the approval of at least one Carlyle Director, if at such time there is at least one Carlyle Director then serving on the Board of Directors, and one
Onex Director, if at such time there is at least one Onex Director then serving on the Board of Directors, and must be a U.S. citizen who is eligible to be issued a DoD personnel security clearance at the level of the Company’s facility
security clearance. An Onex Director may not be appointed to serve as Chairman of the Board. 

  
 10 









 (d) The Onex Directors, in their capacity as Directors, shall not have DoD personnel
security clearances through the Company or the Subsidiaries, regardless of citizenship. The Onex Directors shall not have access to classified information and export-controlled information entrusted to the Company or the Subsidiaries except as
permissible under the National Industrial Security Program and other applicable U.S. laws and regulations; shall refrain from taking any action to control or influence the Company or the Subsidiaries’ classified contracts, their participation
in classified programs, or their corporate policies concerning the security of classified and export controlled information; shall neither seek nor accept classified or export controlled information entrusted to the Company or the Subsidiaries
except as permissible under the National Industrial Security Program and other applicable U.S. laws and regulations; and shall advise the GSC promptly upon becoming aware of (i) any violation or attempted violation of the SCA or contract
provisions regarding industrial security or export controls, or (ii) actions inconsistent with the National Industrial Security Program and other applicable U.S. laws and regulations. The Board of Directors shall not repeal the resolutions
previously adopted by the Board of Directors formally excluding the Onex Directors from access to the classified information entrusted to the Company or the Subsidiaries. 
 (e) Each Stockholder hereby agrees to vote all Voting Shares owned or held of record by such Stockholder at each annual or special meeting of stockholders of the Company at which Directors of the Company
are to be elected, in favor of, or to take all actions by written consent in lieu of any such meeting as are necessary, or other Necessary Action, to cause the election as members of the Board of Directors of those individuals described in
Section 2.1(b)(i)-(iv) in accordance with, and to otherwise effect the intent of, the provisions of this Section 2.1. A Director designated by any Investor Stockholder or group of Investor Stockholders may be removed
from the Board of Directors only by the Investor Stockholder(s), if any, entitled to designate such Director pursuant to this Article II; provided that nothing in this Agreement shall be construed to impair the rights that the
stockholders of the Company may have to remove any Director for cause. 
 (f) The removal of an Outside Director shall not
become effective until the parties shall have complied with the applicable terms of the SCA, which terms currently require that such Outside Director, the Company and DSS be notified, that DSS approve the removal, and that a successor who is
qualified to become an Outside Director within the terms of the SCA be approved by DSS. Notwithstanding the foregoing, however, if immediate removal of an Outside Director is deemed necessary to prevent an actual or possible violation of any statute
or regulation or actual or possible damage to the Company, the Outside Director may be removed at once, although DSS shall be notified prior to or concurrently with such removal. Any Director may resign at any time upon notice to the Company.
Directors need not be stockholders of the Company. 
 (g) The Company shall reimburse the Directors for all reasonable
out-of-pocket expenses incurred in connection with their attendance at meetings of the Board, the board of directors of any of the Company’s Subsidiaries and any committees thereof, including travel, lodging and meal expenses, and the Company
may provide reasonable compensation for service of directors who are not employees of any of the Onex Stockholders, the Carlyle Stockholders or the Company, or any of their respective Affiliates. 

  
 11 









 (h) The Company shall cause the individuals designated in accordance with
Section 2.1(b) to be nominated for election to the Board of Directors, shall solicit proxies in favor thereof, and at each meeting of the stockholders of the Company at which directors of the Company are to be elected, shall recommend
that the stockholders of the Company elect to the Board of Directors each such individual nominated for election at such meeting. 
 (i) The Directors shall be allocated among the three classes of the Board of Directors as follows: (i) so long as the Carlyle Stockholders have the right to designate three Carlyle Directors, one
Carlyle Director shall be allocated to each of Class I, Class II and Class III; (ii) so long as the Onex Stockholders have the right to designate two Onex Directors, one Onex Director shall be allocated to each of Class I and Class II; and
(iii) so long as the Carlyle Stockholders have the right to designate three Carlyle Directors and the Onex Stockholders have the right to designate two Directors, (A) the Management Director shall be allocated to Class III; and
(B) one Outside Director shall be allocated to each of Class II and Class III (and any new Director position created as a result of the expansion of the Board prior to the first anniversary of the Effective Date shall be allocated to Class I).

 (j) Notwithstanding the foregoing, this Section 2.1 confers upon the Investor Stockholders the right, but not the
obligation, to designate Directors, and any Investor Stockholder may, at its option, elect not to exercise any such right to designate a Director or Directors; provided that no election by any Investor Stockholder to refrain from exercising
any such right shall in any way affect such Investor Stockholder’s obligations under this Agreement. 
 SECTION
2.2 Removal. If any Investor Stockholder or group of Investor Stockholders that is entitled to designate a Director notifies the Company and the other Stockholders that such Investor Stockholder or group of Investor Stockholders desires
to remove any Director previously designated by such Investor Stockholder or group of Investor Stockholders, with or without cause, then such Director shall be removed from the Board of Directors and each Stockholder shall take all Necessary Action
to cause such removal of such Director, including voting all Voting Shares in favor of, or executing a written consent authorizing, such removal. In the event that any Investor Stockholder or group of Investor Stockholders ceases to have the right
to designate an individual to serve as a Director pursuant to Section 2.1(b), (i) such Investor Stockholder’s or group’s designee to the Board of Directors shall resign immediately or each Stockholder shall take all
Necessary Action to cause the removal of such individual, including voting all Voting Shares in favor of, or executing a written consent authorizing, such removal, and (ii) the vacancy created by such resignation or removal shall be filled as
provided in the Certificate of Incorporation and the Bylaws. 
 SECTION 2.3 Vacancies. In the event that a vacancy
is created on the Board of Directors at any time by the death, disability, retirement, resignation or removal of any member of the Board of Directors, or for any other reason there shall exist or occur any vacancy on the Board of Directors, each
Stockholder hereby agrees to take such actions as will result in the election or appointment as a Director of an individual designated to fill such vacancy and serve as a Director by the Investor Stockholder(s), if any, that had, pursuant to
Section 2.1(b), 

  
 12 









 
designated the Director whose death, disability, retirement, resignation or removal resulted in such vacancy on the Board of Directors. In the event that no Investor Stockholder has, pursuant to
Section 2.1(b), the right to designate an individual to fill such vacancy, then such vacancy shall be filled as provided in the Certificate of Incorporation and the Bylaws. With respect to the Outside Directors, replacements may be
elected or appointed only with the approval of DSS. Vacancies on the Board of Directors shall not exist for a period of more than ninety (90) days after a director’s retirement, resignation, death, disability or removal unless DSS is
notified of the delay. 
 SECTION 2.4 Covenant to Vote. Each Stockholder hereby agrees to take all Necessary Action
to call, or cause the Company and the appropriate officers and directors of the Company to call, an annual meeting (and when circumstances so require, a special meeting) of stockholders of the Company and to vote all Voting Shares owned or held of
record by such Stockholder at any such meeting and at any other annual or special meeting of stockholders in favor of, or take all actions by written consent in lieu of any such meeting as may be necessary to cause, the election as members of the
Board of Directors of those individuals designated in accordance with Section 2.1(b)(i)-(iv) and to otherwise effect the intent of this Article II. 

SECTION 2.5 Restrictions on Other Agreements. No Stockholder shall grant any proxy or enter into or agree to be bound by any
voting trust with respect to its Shares nor shall any Stockholder enter into any other agreements or arrangements of any kind with any Person with respect to its Shares on terms which conflict with the provisions of this Agreement (whether or not
such proxy, voting trust, agreements or arrangements are with other Stockholders, holders of Common Shares that are not parties to this Agreement or otherwise). 
 SECTION 2.6 Additional Management Provisions. 
 (a) Each Stockholder
and the Company agrees and acknowledges that the directors designated by the Carlyle Stockholders or the Onex Stockholders may share confidential, non-public information about the Company and its subsidiaries with the Carlyle Stockholders and the
Onex Stockholders, respectively, subject to applicable law. 
 (b) The Stockholders and the Company hereby agree,
notwithstanding anything to the contrary in any other agreement or at law or in equity, and subject at all times to the requirements of the SCA, that when the Carlyle Stockholders and/or the Onex Stockholders take any action under this Agreement to
give or withhold its consent, the Carlyle Stockholders and/or the Onex Stockholders, as applicable, shall have no duty (fiduciary or other) to consider the interests of the Company or the other Stockholders and may act exclusively in its own
interest and shall have only the duty to act in good faith; provided, however, that the foregoing shall in no way affect the obligations of the parties hereto to comply with the provisions of this Agreement. 

(c) The Company shall take all Necessary Action to ensure that the Bylaws do not, at any time, conflict with the provisions of this
Agreement or the SCA. 

  
 13 









 (d) In accordance with the SCA, the Board of Directors shall maintain a GSC consisting of
the Outside Directors and the Management Director. The duties and responsibilities of the GSC shall be as described in the SCA. 

ARTICLE III 

TRANSFERS OF SHARES 
 SECTION 3.1 Restrictions on Transfer. 
 (a) Each Carlyle Stockholder
and each Onex Stockholder agrees that it will not Transfer any Shares pursuant to Rule 144 under the Securities Act without the prior written consent of the Onex Stockholders or the Carlyle Stockholders, respectively (such consent not to be
unreasonably withheld); provided, however, that (A) if the Carlyle Stockholders in the aggregate do not then hold Shares representing five percent (5%) or more of the then-outstanding Common Shares, then (i) the Carlyle
Stockholders may Transfer any Shares pursuant to Rule 144 under the Securities Act without obtaining the prior written consent of the Onex Stockholders and (ii) the Onex Stockholders may Transfer any Shares pursuant to Rule 144 under the
Securities Act without obtaining the prior written consent of the Carlyle Stockholders, and (B) if the Onex Stockholders in the aggregate do not then hold Shares representing five percent (5%) or more of the then-outstanding Common Shares,
then the (i) Onex Stockholders may Transfer any Shares pursuant to Rule 144 under the Securities Act without obtaining the prior written consent of the Carlyle Stockholders and (ii) the Carlyle Stockholders may Transfer any Shares pursuant
to Rule 144 under the Securities Act without obtaining the prior written consent of the Onex Stockholders. 
 (b) During the
Restricted Period, without the prior written consent of the Company authorized by affirmative vote of a majority of the members of the Board of Directors, each Restricted Management Stockholder will not Transfer any Pre-IPO Shares to any Person
other than (i) any Transfer to a Permitted Transferee of such Restricted Management Stockholder and (ii) Transfers by such Restricted Management Stockholder following the date that is six months after the closing of the Initial Public
Offering (the “Initial Lockup Expiration Date”) of an aggregate number of Pre-IPO Shares (adjusted for any stock split, stock dividend, sub-division of capital stock and the like) representing not more than the percentage of such
Restricted Management Stockholder’s Pre-IPO Shares equal to the greater of (A) 15% of such Restricted Management Stockholder’s Pre-IPO Shares, which percentage shall increase by 15% of such Restricted Management Stockholder’s
Pre-IPO Shares (up to a maximum of 45% of such Restricted Management Stockholder’s Pre-IPO Shares) on each anniversary of the Initial Lockup Expiration Date and (B) the percentage of Pre-IPO Shares of the Carlyle Stockholders and the Onex
Stockholders Transferred by the Carlyle Stockholders and the Onex Stockholders (excluding Transfers to Permitted Transferees of the Carlyle Stockholders and the Onex Stockholders) on or prior to such date; provided, however, that
following the termination of such Restricted Management Stockholder’s employment with the Company or Allison Transmission, Inc., this clause (ii) shall not prohibit a Transfer of Pre-IPO Shares by such Restricted Management Stockholder to
the extent clause (ii) would prevent a Restricted Management Stockholder from obtaining from such Transfer the net proceeds required to pay the exercise price and/or taxes related to an exercise of Vested Options. 

  
 14 









 SECTION 3.2 Endorsement of Certificates. All certificates representing Shares
issued to or acquired by any of the Stockholders prior to the execution of this Agreement were endorsed as follows: 
 THE SECURITIES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO, AND ARE TRANSFERABLE ONLY UPON COMPLIANCE WITH, THE PROVISIONS OF A STOCKHOLDERS AGREEMENT, DATED AUGUST 7, 2007, AMONG THE COMPANY AND ITS
STOCKHOLDERS. COPIES OF THE ABOVE REFERENCED AGREEMENTS ARE ON FILE AT THE PRINCIPAL EXECUTIVE OFFICE OF THE COMPANY AND MAY BE OBTAINED FROM THE COMPANY AT ITS PRINCIPAL EXECUTIVE OFFICE. 

THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933 OR THE SECURITIES
LAWS OF ANY STATE AND MAY NOT BE TRANSFERRED EXCEPT PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT, OR AN EXEMPTION FROM REGISTRATION, UNDER SAID ACT AND SUCH LAWS. 
 Upon the execution of this Agreement, in addition to any other legend which the Company may deem advisable under the Securities Act and applicable state securities laws, all certificates, if any,
representing Shares hereafter issued by the Company to any of the Stockholders shall bear the following legend, and the Shares represented by such certificates shall be subject to the applicable provisions of this Agreement: 

THE SECURITIES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO THE PROVISIONS OF THAT CERTAIN AMENDED AND RESTATED
STOCKHOLDERS AGREEMENT, DATED MARCH 12, 2012, AMONG THE COMPANY AND CERTAIN OF ITS STOCKHOLDERS. COPIES OF THE ABOVE REFERENCED AGREEMENT ARE ON FILE AT THE PRINCIPAL EXECUTIVE OFFICE OF THE COMPANY AND MAY BE OBTAINED FROM THE COMPANY AT ITS

At the request of the Stockholder, the Company shall remove the legend referring to the Securities Act from the certificates representing
its Shares and upon the earliest of the following events: (i) when such Shares are Transferred in a Public Offering; (ii) when such Shares are Transferred after an Initial Public Offering pursuant to Rule 144 under the Securities Act; or
(iii) when such Shares are Transferred in any other transaction if the seller delivers to the 

  
 15 









 
Company an opinion of its counsel, which counsel and opinion shall be reasonably satisfactory to the Company, to the effect that such legend is no longer necessary in order to protect the Company
against a violation by it of the Securities Act upon any sale or other disposition of such Shares without registration thereunder. The Company covenants that it shall keep a copy of this Agreement on file for the purpose of furnishing copies to the
holders of record of Shares. At the request of the Stockholder, the Company shall remove the legend referring to the Stockholders Agreement at such time as this Agreement no longer imposes restrictions on the Shares. 

ARTICLE IV 

TAG-ALONG RIGHTS 

SECTION 4.1 Tag-Along Rights. 
 (a) If a Carlyle Stockholder or an Onex Stockholder proposes to Transfer (each, a “Disposing Stockholder”) (other than Transfers permitted pursuant to Section 4.2(a)(i) or
(ii) or any Transfer to be effected pursuant to a Public Offering or Rule 144 under the Securities Act), any of its issued and outstanding Shares or securities convertible into, or exchangeable or exercisable for Shares (the
“Tag-Along Securities”), such Disposing Stockholder shall refrain from effecting such transaction or transactions unless, prior to the consummation thereof, the other Investor Stockholders (the “Tag-Along
Stockholders”) shall have been afforded the opportunity to join in such transaction or transactions on a pro rata basis, as hereinafter provided. 
 (b) Prior to consummation of any proposed Transfer of shares of the Tag-Along Securities described in Section 4.1(a), the Disposing Stockholder or Stockholders shall cause the Person or group
of Persons that proposes to acquire such Shares (the “Proposed Purchaser”) to offer (the “Purchase Offer”) in writing to each other Investor Stockholder, such that the number of Shares so offered to be purchased
from such Investor Stockholder shall be equal to the product of (i) the total number of Shares then owned by such Investor Stockholder multiplied by (ii) a fraction, the numerator of which is the aggregate number of Shares proposed to be
purchased by the Proposed Purchaser from all Investor Stockholders and the denominator of which is the aggregate number of Shares then held by all Investor Stockholders (for these purposes, all securities and other rights convertible into or
exchangeable or exercisable for Shares shall be deemed to have been so converted, exchanged, or exercised, other than any such securities or other rights that have an exercise or conversion price per Share greater than the price per Share to be paid
by the Proposed Purchaser). Such purchase shall be made at the same price per Share and on such other terms and conditions as the Proposed Purchaser has offered to purchase the Tag-Along Securities to be sold by the Disposing Stockholder or
Stockholders. Each Tag-Along Stockholder shall have five (5) business days from the date of receipt of the Purchase Offer to accept such Purchase Offer, and the closing of such purchase shall occur simultaneously with the purchase of the
Tag-Along Securities from the Disposing Stockholder(s). Unless the Proposed Purchaser agrees to purchase 100% of the Shares then held by all Investor Stockholders, the number of Shares to be sold to the Proposed Purchaser by the Disposing
Stockholder or Stockholders shall be reduced by the aggregate number of Shares purchased by the Proposed Purchaser from the Tag-Along Stockholders pursuant to the provisions of this Section 4.1(b). 

  
 16 









 (c) Any Transfer of Shares by a Tag-Along Stockholder to the Proposed Purchaser pursuant to
this Section 4.1 shall be on the same terms and conditions (including price, time of payment and form of consideration) as the Transfer of the Tag-Along Securities by the Disposing Stockholder(s) to the Proposed Purchaser;
provided that, in order to be entitled to exercise its tag along right pursuant to this Section 4.1, each Tag-Along Stockholder must agree to make to the Proposed Purchaser representations, warranties, covenants, indemnities and
agreements the same mutatis mutandis as those made by the Disposing Stockholder(s) in connection with the relevant transaction and agree to the same conditions to the relevant transaction as the Disposing Stockholder(s) agrees.

 (d) Notwithstanding anything to the contrary in this Section 4.1, the provisions of this Section 4.1
shall terminate if either (i) the Carlyle Stockholders in the aggregate do not hold Shares representing five percent (5%) or more of the then-outstanding Common Shares or (ii) the Onex Stockholders in the aggregate do not hold Shares
representing five percent (5%) or more of the then-outstanding Common Shares. 
 SECTION 4.2 Exceptions to
Tag-Along Rights. 
 (a) The provisions of Section 4.1 shall not apply to any of the following Transfers:
(i) any Transfer of Shares from any Onex Stockholder to any of its Permitted Transferees; or (ii) any Transfer of Shares from any Carlyle Stockholder to any of its Permitted Transferees; provided that, in each case set forth in
clauses (i) and (ii) of this Section 4.2(a), the transferee in question becomes a party to this Agreement and agrees to be bound hereby by executing a supplemental signature page to this Agreement in the form attached hereto as
Exhibit A. 
 (b) Each Permitted Transferee of any Investor Stockholder to which Shares are Transferred shall, and
such Investor Stockholder shall cause such Permitted Transferee to, Transfer back to such Investor Stockholder (or to another Permitted Transferee of such Investor Stockholder) any Shares it owns if such Permitted Transferee ceases to be a Permitted
Transferee of such Investor Stockholder. 
 ARTICLE V 
 REGISTRATION RIGHTS 
 SECTION 5.1 Demand Registrations. 

(a) Demand by Holders. At any time and from time to time, the Qualified Investor Stockholders may make a written request to the
Company for Registration of Registrable Securities held by such Qualified Investor Stockholders and any other Holders of Registrable Securities. Any such requested Registration shall hereinafter be referred to as a “Demand
Registration.” Any Demand Registration may request that the Company register Registrable Securities on an appropriate form, including a Shelf Registration Statement and, if the Company is a WKSI, an automatic shelf registration statement.
Each request for a Demand Registration shall specify the kind and aggregate amount of Registrable Securities to be Registered and the intended methods of disposition thereof. Within thirty (30) days of a request for a Demand Registration, the
Company shall file a Registration Statement relating to such Demand 

  
 17 









 
Registration (a “Demand Registration Statement”), and shall use its best efforts to cause such Demand Registration Statement to promptly (but in any event within 180 days of
receipt of the written request for a Demand Registration) be declared effective under the Securities Act; provided that, to the extent the Company will be a WKSI at the time such Demand Registration Statement is filed with the SEC, the
Company shall file such Demand Registration Statement within five (5) business days of such Demand Registration. 
 (b)
Limitation on Demand Registration. The Company shall not be obligated to file a Demand Registration Statement under this Section 5.1 unless the aggregate purchase price of the Registrable Securities to be included in the requested
registration (determined by reference to the offering price on the cover of the registration statement proposed to be filed) is greater than $25,000,000. 
 (c) Demand Withdrawal. A Holder may withdraw its Registrable Securities from a Demand Registration at any time prior to the effectiveness of the applicable Demand Registration Statement. Upon
receipt of notices from all initiating Holders to such effect, the Company shall cease all efforts to secure effectiveness of the applicable Demand Registration Statement. 
 (d) Effective Registration. A registration request pursuant to Section 5.1(a) shall not be deemed a Demand Registration unless the Demand Registration Statement is declared effective by
the SEC (or, in the case of a Demand Registration Statement filed with the SEC when the Company is a WKSI, when such Demand Registration Statement is so filed) and remains effective for not less than 180 days (or such shorter period as will
terminate when all Registrable Securities covered by such Demand Registration Statement have been sold) or, if such Registration Statement relates to an Underwritten Offering, such longer period as in the opinion of counsel for the underwriter or
underwriters a Prospectus is required by law to be delivered in connection with sales of Registrable Securities by an underwriter or dealer (the applicable period, the “Demand Period”). No Demand Registration shall be deemed to have
been effected if (i) during the Demand Period such registration is interfered with by any stop order, injunction or other order or requirement of the SEC or other governmental agency or court or (ii) the conditions to closing specified in
the underwriting agreement, if any, entered into in connection with such registration are not satisfied other than by reason of a wrongful act, misrepresentation or breach of such applicable underwriting agreement by a participating Holder.

 (e) Demand Notice. Other than in connection with the Initial Public Offering, promptly upon receipt of any request for
a Demand Registration pursuant to Section 5.1(a) (but in no event more than five (5) business days thereafter or, if the Company is a WKSI at the time such Demand Registration is submitted to the Company, one (1) business day
thereafter), the Company shall deliver a written notice (a “Demand Notice”) of any such Registration request to all other Holders of Registrable Securities, and the Company shall include in such Demand Registration (other than a
Demand Registration related to the Initial Public Offering) all such Registrable Securities with respect to which the Company has received written requests for inclusion therein within ten (10) business days or, if the Company is a WKSI at the
time such Demand Registration is submitted to the Company, three (3) business days, in each case, after the date that the Demand Notice has been delivered. All requests made pursuant to this Section 5.1(e) shall specify the
aggregate amount of Registrable Securities to be registered and 

  
 18 









 
the intended method of distribution of such securities. The parties acknowledge and agree that an Initial Public Offering shall constitute a Demand Registration effected pursuant to
Section 5.1(a) of the Agreement. 
 (f) Preemption. If not more than thirty (30) days prior to receipt
of any request for a Demand Registration pursuant to Section 5.1(a) the Company shall have (i) circulated to prospective underwriters and their counsel a draft of a Registration Statement for a primary offering of equity securities
on behalf of the Company, (ii) solicited bids for a primary offering of Common Shares, or (iii) otherwise reached an understanding with an underwriter with respect to a primary offering of Common Shares, the Company may preempt the Demand
Registration with such primary offering by delivering written notice of such intention (the “Preemption Notice”) to the Holders making a request for a Demand Registration within three (3) business days after the Company has
received the request. The period of preemption may be up to forty-five (45) days following the date of the Preemption Notice. Notwithstanding anything to the contrary herein, the Company shall not be entitled to exercise its right to preempt a
Demand Registration pursuant to this Section 5.1(f) more than once during any twelve (12) month period. 
 (g)
Delay in Filing; Suspension of Registration. If the filing, initial effectiveness or continued use of a Demand Registration Statement at any time would require the Company to make an Adverse Disclosure, the Company may, upon giving prompt
written notice of such action to the Holders, delay the filing or initial effectiveness of, or suspend use of, the Demand Registration Statement (a “Demand Suspension”); provided, however, that the Company shall not be
permitted to exercise a Demand Suspension (i) more than once during any twelve (12) month period or (ii) for a period exceeding thirty (30) days on any one occasion. In the case of a Demand Suspension, the Holders agree to
suspend use of the applicable Prospectus in connection with any sale or purchase, or offer to sell or purchase, Registrable Securities, upon receipt of the notice referred to above. The Company shall immediately notify the Holders upon the
termination of any Demand Suspension, amend or supplement the Prospectus, if necessary, so it does not contain any untrue statement or omission and furnish to the Holders such numbers of copies of the Prospectus as so amended or supplemented as the
Holders may request. The Company agrees, if necessary, to supplement or make amendments to the Demand Registration Statement, if required by the registration form used by the Company for the Demand Registration or by the instructions applicable to
such registration form or by the Securities Act or the rules or regulations promulgated thereunder or as may be requested by the Holders of a majority of the Registrable Securities that are included in such Demand Registration Statement. 

(h) Underwritten Offering. If the Holders of not less than a majority of the Registrable Securities requesting a Demand
Registration so elect, such offering of Registrable Securities shall be in the form of an Underwritten Offering. The Holders of a majority of such Registrable Securities included in such Underwritten Offering shall have the right to select the
managing underwriter or underwriters to administer the offering; provided that such managing underwriter or underwriters shall be reasonably acceptable to the Company. 
 (i) Priority of Securities Registered Pursuant to Demand Registrations. If the managing underwriter or underwriters of a proposed Underwritten Offering of the Registrable Securities included in a
Demand Registration (or, in the case of a Demand Registration not being underwritten, the Holders of a majority of the Registrable Securities included therein), advise the 

  
 19 









 
Holders initiating such Demand Registration in writing that, in its or their opinion, the number of securities requested to be included in such Demand Registration exceeds the number which can be
sold in such offering without being likely to have a significant adverse effect on the price, timing or distribution of the securities offered or the market for the securities offered, then the Company will include in such registration,
(i) first, the number of Registrable Securities requested by all Holders of Registrable Securities to be included in such registration that, in the opinion of such managing underwriter(s), can be sold, such amount to be allocated among
all such Holders of Registrable Securities pro rata on the basis of the respective number of Registrable Securities then held by each such Holder, (ii) second, only if all of the Registrable Securities referred to in
clause (i) have been included in such Registration, the securities the Company proposes to sell and (iii) third, only if all of the securities referred to in clause (ii) have been included in such Registration, any other
securities eligible for inclusion in such Registration. 
 SECTION 5.2 Piggyback Registration. 

(a) Participation. Other than in connection with the Initial Public Offering, if the Company at any time proposes to file a
Registration Statement under the Securities Act with respect to any offering of its Common Shares for its own account or for the account of any other Persons (other than (i) a Registration under Section 5.1, (ii) a Registration
on Form S-4 or S-8 or any successor form to such Forms or (iii) a Registration of securities solely relating to an offering and sale to employees or directors of the Company pursuant to any employee stock plan or other employee
benefit plan arrangement), then, as soon as practicable (but in no event less than thirty (30) days prior to the proposed date of filing such Registration Statement), the Company shall give written notice of such proposed filing to all Holders
of Registrable Securities, and such notice shall offer the Holders of such Registrable Securities the opportunity to Register under such Registration Statement such number of Registrable Securities as each such Holder may request in writing (a
“Piggyback Registration”). Subject to Section 3.1(b) and Section 5.2(b), the Company shall include in such Registration Statement all such Registrable Securities which are requested to be included therein
within fifteen (15) days or, if the Company is a WKSI at such time, five (5) business days, in each case, after the receipt by such Holder of any such notice; provided, however, that if at any time after giving written notice
of its intention to Register any securities and prior to the effective date of the Registration Statement filed in connection with such Registration, the Company shall determine for any reason not to Register or to delay Registration of such
securities, the Company shall give written notice of such determination to each Holder of Registrable Securities and, thereupon, (i) in the case of a determination not to Register, shall be relieved of its obligation to Register any Registrable
Securities in connection with such Registration (but not from its obligation to pay the Registration Expenses in connection therewith), without prejudice, however, to the rights of any Holders of Registrable Securities entitled to request that such
Registration be effected as a Demand Registration under Section 5.1, and (ii) in the case of a determination to delay registering, in the absence of a request for a Demand Registration, shall be permitted to delay registering any
Registrable Securities, for the same period as the delay in registering such other securities. If the offering pursuant to such Registration Statement is to be underwritten, then each Holder making a request for a Piggyback Registration pursuant to
this Section 5.2(a) must, and the Company shall make such arrangements with the managing underwriter or underwriters so that each such Holder may, participate in such Underwritten Offering. If the offering pursuant


  
 20 









 
to such Registration Statement is to be on any other basis, then each Holder making a request for a Piggyback Registration pursuant to this Section 5.2(a) must, and the Company shall
make such arrangements so that each such Holder may, participate in such offering on such basis. Each Holder of Registrable Securities shall be permitted to withdraw all or part of such Holder’s Registrable Securities from a Piggyback
Registration at any time prior to the effective date of such Registration. 
 (b) Priority of Piggyback Registration. If
the managing underwriter or underwriters of any proposed Underwritten Offering of Registrable Securities included in a Piggyback Registration informs the Company in writing that, in its or their opinion, the number of securities which such Holders
and any other Persons intend to include in such offering exceeds the number which can be sold in such offering without being likely to have a significant adverse effect on the price, timing or distribution of the securities offered or the market for
the securities offered, then the securities to be included in such Registration shall be (i) first, the number of Registrable Securities that the Company proposes to sell, that, in the opinion of such managing underwriter(s), can be
sold, (ii) second, only if all securities referred to in clause (i) have been included in such Registration, the number of Registrable Securities requested by all Holders of Registrable Securities to be included in such
Registration, that, in the opinion of such managing underwriter(s), can be sold, such amount to be allocated among all such Holders of Registrable Securities pro rata on the basis of the respective number of Registrable Securities then
held by each such Holder, and (iii) third, only if all securities referred to in clauses (i) and (ii) have been included in such Registration, the number of Registrable Securities that any other Person exercising a contractual
right to demand Registration proposes to sell, that, in the opinion of such managing underwriter(s), can be sold. 
 (c) No
Effect on Demand Registrations. No Registration of Registrable Securities effected pursuant to a reasonable request under this Section 5.2 shall be deemed to have been effected pursuant to Section 5.1 or shall relieve the
Company of its obligations under Section 5.1. 
 SECTION 5.3 Registration Procedures.

Registrable Securities covered by such Registration Statement, copies of all documents prepared to be filed or used, which documents shall be subject to the review of such underwriters and such Holders and their respective counsel and
(y) except in the case of a Registration under Section 5.2, not file or use any Registration Statement or Prospectus or amendments or supplements thereto or any free writing prospectus related thereto to which the Holders of a

effectiveness of such Registration Statement or any order by the SEC or any other regulatory authority preventing or suspending the use of any preliminary or final Prospectus or the initiation or threatening of any proceedings for such purposes,
(d) if, at any time, the representations and warranties of the Company in any applicable underwriting agreement cease to be true and correct and in all material respects, and (e) of the receipt by the Company of any notification with
respect to the suspension of the qualification of the Registrable Securities for offering or sale in any jurisdiction or the initiation or threatening of any proceeding for such purpose; 

(v) promptly notify each selling Holder of Registrable Securities and the managing underwriter or underwriters, if any,
when the Company becomes aware of the happening of any event as a result of which the applicable Registration Statement or the Prospectus included in such Registration Statement (as then in effect) or any free writing prospectus related thereto or
the information conveyed to any purchaser at the time of sale to such purchaser contains any untrue statement of a material fact or omits to state a material fact necessary to make the statements therein (in the case of such Prospectus, any
preliminary Prospectus, any free writing prospectus and any information conveyed to any purchaser at the time of the sale to such purchaser, in light of the circumstances under which they were made) not misleading or, if for any other reason it
shall be 

  
 22 









 
necessary during such time period to amend or supplement such Registration Statement or Prospectus, any free writing prospectus related thereto or any information conveyed to any purchaser at the
time of the sale to such purchaser in order to comply with the Securities Act and, in either case as promptly as practicable thereafter, prepare and file with the SEC, and furnish without charge to the selling Holders and the managing underwriter or

notified of the matters to be incorporated in such Prospectus supplement or post-effective amendment; 
 (viii)

consents to the use of such Prospectus or any amendment or supplement thereto or any free writing prospectus relating thereto by each of the selling Holders of Registrable Securities and the underwriters, if any, in connection with the offering and
sale of the Registrable Securities covered by such Prospectus or any amendment or supplement thereto) and such other documents as such selling Holder or underwriter may request in order to facilitate the disposition of the Registrable Securities by
such Holder or underwriter;

 (xi) cooperate with the selling Holders of Registrable Securities and the managing underwriter or underwriters, if any, to facilitate the timely preparation and delivery of certificates representing

the underwriters or agents, if any, in form, substance and scope as are customarily made by issuers in secondary underwritten public offerings;

 24 









 (xvii) obtain for delivery to the Holders of Registrable Securities being
registered and to the underwriter or underwriters, if any, an opinion or opinions from counsel for the Company dated the effective date of the Registration Statement or, in the event of an Underwritten Offering, the date of the closing under the

(xviii) in the case of an Underwritten Offering, use its reasonable best efforts to obtain for delivery to the Company and
the managing underwriter or underwriters, with copies to the Holders of Registrable Securities included in such Registration, a cold comfort letter from the Company’s independent certified public accountants in customary form and covering such

 (xxii) use its reasonable best efforts to comply with all applicable securities laws and make available to its security holders, as soon as practicable, an earnings statement satisfying the provisions of
Section 11(a) of the Securities Act and the rules and regulations promulgated thereunder; 
 (xxiii) provide
and cause to be maintained a transfer agent and registrar for all Registrable Securities covered by the applicable Registration Statement from and after a date not later than the effective date of such Registration Statement; 

  
 25 









 (xxiv) use its reasonable best efforts to cause all Registrable Securities
covered by the applicable Registration Statement to be listed on each securities exchange on which any of the Company’s securities are then listed or quoted and on each inter dealer quotation system on which any of the Company’s securities

 (xxv) make available upon reasonable notice at reasonable times and for reasonable periods
for inspection by a representative appointed by the Holders of a majority of Registrable Securities covered by the applicable Registration Statement, by any underwriter participating in any disposition to be effected pursuant to such Registration
Statement and by any attorney, accountant or other agent retained by such Holders or any such underwriter, all pertinent financial and other records, pertinent corporate documents and properties of the Company, and use its reasonable best efforts to
cause all of the Company’s officers, directors and employees and the independent public accountants who have certified its financial statements to make themselves available to discuss the business of the Company and to supply all information
requested by any such Person in connection with such Registration Statement as shall be necessary to enable them to exercise their due diligence responsibility; provided, however, that any such Person gaining access to information
regarding the Company pursuant to this Section 5.3(a)(xxv) shall agree to hold in strict confidence and shall not make any disclosure or use any information regarding the Company which the Company determines in good faith to be
confidential, and of which determination such Person is notified, unless (w) the release of such information is requested or required (by deposition, interrogatory, requests for information or documents by a governmental entity, subpoena or
similar process), (x) such information is or becomes publicly known without a breach of this or any other agreement of which such Person has knowledge, (y) such information is or becomes available to such Person on a non-confidential basis
from a source other than the Company or (z) such information is independently developed by such Person; 

(xxvi) in the case of an Underwritten Offering, cause the senior executive officers of the Company to participate in the
customary “road show” presentations that may be reasonably requested by the managing underwriter or underwriters in any such Underwritten Offering and otherwise to facilitate, cooperate with, and participate in each proposed offering
contemplated herein and customary selling efforts related thereto. 
 (xxvii) take all reasonable action to
ensure that any free writing prospectus utilized in connection with any registration covered by Section 5.1 or 5.2 complies in all material respects with the Securities Act, is filed in accordance with the Securities Act to the
extent required thereby, is retained in accordance with the Securities Act to the extent required thereby and, when taken together with the related Prospectus, Prospectus supplement and related documents, will not contain any untrue statement of a
material fact or omit to state a material fact necessary to make the statements therein, in light of the circumstances under which they were made, not misleading; and 

(xxviii) in connection with any Underwritten Offering, if at any time the information conveyed to a purchaser at the time
of sale to such purchaser includes any untrue statement of a material fact or omits to state any material fact necessary in order to 

  
 26 









 
make the statements therein, in light of the circumstances under which they were made, not misleading, promptly file with the SEC such amendments or supplements to such information as may be
necessary so that the statements as so amended or supplemented will not, in light of the circumstances, be misleading. 
 To the
extent the Company is a well-known seasoned issuer (as defined in Rule 405 under the Securities Act) (a “WKSI”) at the time any Demand Registration is submitted to the Company, and such Demand Registration requests that the
Company file an automatic shelf registration statement (as defined in Rule 405 under the Securities Act) (an “Automatic Shelf Registration Statement”) on Form S-3, the Company shall file an Automatic Shelf Registration
Statement which covers those Registrable Securities which are requested to be registered. If the Company does not pay the filing fee covering the Registrable Securities at the time the Automatic Shelf Registration Statement is filed, the Company
agrees to pay such fee at such time or times as the Registrable Securities are to be sold. If the Automatic Shelf Registration Statement has been outstanding for at least three (3) years, at the end of the third year the Company shall refile a
new Automatic Shelf Registration Statement covering the Registrable Securities. If at any time when the Company is required to re-evaluate its WKSI status the Company determines that it is not a WKSI, the Company shall use its reasonable best
efforts to refile the Automatic Shelf Registration Statement on Form S-3 and, if such form is not available, Form S-1 and keep such registration statement effective during the period during which such registration statement is required to
be kept effective. 
 If the Company files any Shelf Registration Statement for the benefit of the holders of any of its
securities other than the Holders, the Company agrees that it shall include in such Shelf Registration Statement such disclosures as may be required by Rule 430B (referring to the unnamed selling security holders in a generic manner by
identifying the initial offering of the securities to the Holders) in order to ensure that the Holders may be added to such Shelf Registration Statement at a later time through the filing of a Prospectus supplement rather than a post-effective
amendment. 
 (b) The Company may require each seller of Registrable Securities as to which any Registration is being effected
to furnish to the Company such information regarding the distribution of such securities and such other information relating to such Holder and its ownership of Registrable Securities as the Company may from time to time request in writing. Each
Holder of Registrable Securities agrees to furnish such information to the Company and to cooperate with the Company as reasonably necessary to enable the Company to comply with the provisions of this Agreement. 

(c) Each Holder of Registrable Securities agrees that, upon receipt of any notice from the Company of the happening of any event of the
kind described in Section 5.3(a)(v), such Holder will forthwith discontinue disposition of Registrable Securities pursuant to such Registration Statement until such Holder’s receipt of the copies of the supplemented or amended
Prospectus contemplated by Section 5.3(a)(v), or until such Holder is advised in writing by the Company that the use of the Prospectus may be resumed, and if so directed by the Company, such Holder shall deliver to the Company (at the
Company’s expense) all copies, other than permanent file copies then in such Holder’s possession, of the Prospectus covering such Registrable Securities current at the time of receipt of such notice. In the event the Company shall give any
such 

  
 27 









 
notice, the period during which the applicable Registration Statement is required to be maintained effective shall be extended by the number of days during the period from and including the date
of the giving of such notice to and including the date when each seller of Registrable Securities covered by such Registration Statement either receives the copies of the supplemented or amended Prospectus contemplated by
Section 5.3(a)(v) or is advised in writing by the Company that the use of the Prospectus may be resumed. 
 (d) If
any such Registration Statement or comparable statement under “Blue Sky” laws refers to any Holder by name or otherwise as the Holder of any securities of the Company, then such Holder shall have the right to require (i) the insertion
therein of language, in form and substance satisfactory to such Holder and the Company, to the effect that the holding by such Holder of such securities is not to be construed as a recommendation by such Holder of the investment quality of the
Company’s securities covered thereby and that such holding does not imply that such Holder will assist in meeting any future financial requirements of the Company, or (ii) in the event that such reference to such Holder by name or
otherwise is not in the judgment of the Company, as advised by counsel, required by the Securities Act or any similar federal statute or any state “Blue Sky” or securities law then in force, the deletion of the reference to such Holder.

 SECTION 5.4 Underwritten Offerings. 
 (a) Demand Registrations. If requested by the underwriters for any Underwritten Offering requested by Holders of Registrable Securities pursuant to a Demand Registration under
Section 5.1, the Company shall enter into an underwriting agreement with such underwriters for such offering, such agreement to be in substance, form and otherwise reasonably satisfactory in substance and form to the Holders of a
majority of the Registrable Securities to be included in such underwriting, and to contain such representations and warranties by the Company and such other terms as are generally prevailing in agreements of that type, including indemnities no less
favorable to the recipient thereof than those provided in Section 5.6. The Holders of the Registrable Securities proposed to be distributed by such underwriters shall cooperate with the Company in the negotiation of the underwriting
agreement and shall give consideration to the reasonable suggestions of the Company regarding the form thereof. Such Holders of Registrable Securities to be distributed by such underwriters shall be parties to such underwriting agreement, which
underwriting agreement shall (i) contain such representations and warranties by, and the other agreements on the part of, the Company to and for the benefit of such Holders of Registrable Securities as are customarily made by issuers to selling
stockholders in secondary underwritten public offerings and (ii) provide that any or all of the conditions precedent to the obligations of such underwriters under such underwriting agreement also shall be conditions precedent to the obligations
of such Holders of Registrable Securities. 
 (b) Piggyback Registrations. If the Company proposes to register any of its
securities under the Securities Act as contemplated by Section 5.2 and such securities are to be distributed in an Underwritten Offering through one or more underwriters, the Holders of Registrable Securities to be distributed by such
underwriters shall be parties to the underwriting agreement between the Company and such underwriters, which underwriting agreement shall (i) be in a form approved by the Company and (ii) provide that any or all of the conditions precedent
to the obligations of such underwriters under such underwriting agreement also shall be conditions precedent to the obligations of such Holders of Registrable Securities. 

  
 28 









 (c) Participation in Underwritten Registrations. No Person may participate in any
Underwritten Offering hereunder unless such Person (i) agrees to sell such Person’s securities on the basis provided in, and agrees to become a party to, any underwriting arrangements approved by the Persons entitled to approve such
arrangements and (ii) completes and executes all questionnaires, powers of attorney, indemnities, underwriting agreements and other documents required under the terms of such underwriting arrangements. 

(d) Price and Underwriting Discounts. In the case of an Underwritten Offering under Section 5.1, the price,
underwriting discount and other financial terms for the Registrable Securities shall be determined by the Holders of a majority of the Registrable Securities included in the Underwritten Offering. In addition, in the case of any Underwritten
Offering, each of the Holders may withdraw their request to participate in the registration pursuant to Section 5.1 after being advised of such price, discount and other terms and shall not be required to enter into any agreements or
documentation that would require otherwise. 
 SECTION 5.5 Registration Expenses. All expenses incident to the
Company’s performance of or compliance with this Agreement shall be paid by the Company, including (i) all registration and filing fees, and any other fees and expenses associated with filings required to be made with the SEC or FINRA,
(ii) all fees and expenses in connection with compliance with any securities or “Blue Sky” laws and determination of the eligibility of the Registrable Securities for investment under the laws of the various jurisdictions,
(iii) all printing, duplicating, word processing, messenger, telephone, facsimile and delivery expenses (including expenses of printing certificates for the Registrable Securities in a form eligible for deposit with The Depository Trust Company
and of printing prospectuses), (iv) all fees and disbursements of counsel for the Company and of all independent certified public accountants of the Company (including the expenses of any special audit and cold comfort letters required by or
incident to such performance), (v) Securities Act liability insurance or similar insurance if the Company so desires or the underwriters so require in accordance with then-customary underwriting practice, (vi) all fees and expenses
incurred in connection with the listing of the Registrable Securities on any securities exchange or quotation of the Registrable Securities on any inter-dealer quotation system, (vii) all applicable rating agency fees with respect to the
Registrable Securities, (viii) all reasonable fees and disbursements of (A) one law firm or other counsel selected by the Holders of a majority of the Registrable Securities owned by the Carlyle Stockholders and their Affiliates being
registered and (B) one law firm or other counsel selected by the Holders of a majority of the Registrable Securities owned by the Onex Stockholders and their Affiliates being registered, (ix) any reasonable fees and disbursements of
underwriters customarily paid by issuers or sellers of securities, (x) all fees and expenses of any special experts or other Persons retained by the Company in connection with any Registration, (xi) fees and expenses of a Qualified
Independent Underwriter (as such term is defined in FINRA Rule 5121(f)(12)) and its counsel, if any, (xii) all fees and disbursements of the underwriters (other than underwriting discounts and commissions) and (xiii) all expenses incurred
in connection with promotional efforts or “roadshows”. All such expenses are referred to herein as “Registration Expenses”. 

  
 29 









 SECTION 5.6 Indemnification. 

(a) Indemnification by the Company. The Company agrees to indemnify and hold harmless, to the full extent permitted by law, each
Holder of Registrable Securities, each member, limited or general partner thereof, each member, limited or general partner of each such member, limited or general partner, each of their respective Affiliates, officers, directors, stockholders,
employees, advisors, and agents and each Person who controls (within the meaning of the Securities Act or the Exchange Act) such Persons and each of their respective representatives from and against any and all losses, penalties, judgments, suits,
costs, claims, damages, liabilities and expenses, joint or several (including reasonable costs of investigation and legal expenses) (each, a “Loss” and collectively “Losses”) arising out of or based upon
(i) any untrue or alleged untrue statement of a material fact contained in any Registration Statement under which such Registrable Securities were registered under the Securities Act (including any final, preliminary or summary Prospectus
contained therein or any amendment thereof or supplement thereto or any documents incorporated by reference therein) or contained in any free writing prospectus utilized in connection therewith or in any information conveyed to any purchaser at the
time of the sale to such purchaser, or any other disclosure document produced by or on behalf of the Company or any of its Subsidiaries, including reports and other documents filed under the Exchange Act, (ii) any omission or alleged omission
to state therein a material fact required to be stated therein or necessary to make the statements therein (in the case of a Prospectus, preliminary Prospectus, free writing prospectus related thereto or the information conveyed to any purchaser at
the time of the sale to such purchaser, in light of the circumstances under which they were made) not misleading, (iii) any actions or inactions or proceedings in respect of the foregoing whether or not such indemnified party is a party thereto
or (iv) any registration or qualification of securities under “Blue Sky” laws; provided, however, that the Company shall not be liable to any particular indemnified party to the extent that any such Loss arises out of or
is based upon an untrue statement or alleged untrue statement or omission or alleged omission made in any such Registration Statement or other disclosure document in reliance upon and in conformity with written information furnished to the Company
by such indemnified party expressly for use in the preparation thereof. This indemnity shall be in addition to any liability the Company may otherwise have. Such indemnity shall remain in full force and effect regardless of any investigation made by
or on behalf of such Holder or any indemnified party and shall survive the Transfer of such securities by such Holder. The Company shall also indemnify underwriters, selling brokers, dealer managers and similar securities industry professionals
participating in the distribution, their officers and directors and each Person who controls such Persons (within the meaning of the Securities Act or the Exchange Act) to the same extent as provided above with respect to the indemnification of the
indemnified parties. 
 (b) Indemnification by the Selling Holder of Registrable Securities. Each selling Holder of
Registrable Securities agrees (severally and not jointly) to indemnify and hold harmless, to the fullest extent permitted by law, the Company, its directors and officers and each Person who controls the Company (within the meaning of the Securities
Act or the Exchange Act) from and against any Losses resulting from (i) any untrue statement of a material fact contained in any Registration Statement under which such Registrable Securities were registered under the Securities Act (including
any final, preliminary or summary Prospectus contained therein or any amendment thereof or supplement thereto or any documents incorporated by reference therein) or contained in any free writing prospectus utilized in connection therewith, or
(ii) any omission to state therein a material fact required to be stated therein or necessary to make the statements 

  
 30 









 
therein (in the case of a Prospectus, preliminary Prospectus or free writing prospectus related thereto, in light of the circumstances under which they were made) not misleading, to the extent,
but only to the extent, that such untrue statement or omission is contained in any information furnished in writing by such selling Holder to the Company specifically for inclusion in such Registration Statement and has not been corrected in a
subsequent writing prior to or concurrently with the sale of the Registrable Securities to the Person asserting the claim. In no event shall the liability of any selling Holder of Registrable Securities hereunder be greater in amount than the dollar
amount of the net proceeds received by such Holder under the sale of Registrable Securities giving rise to such indemnification obligation. 
 (c) Conduct of Indemnification Proceedings. Any Person entitled to indemnification hereunder shall (1) give prompt written notice to the indemnifying party of any claim with respect to which
it seeks indemnification (provided that any delay or failure to so notify the indemnifying party shall relieve the indemnifying party of its obligations hereunder only to the extent, if at all, that it is actually and materially prejudiced by
reason of such delay or failure) and (2) permit such indemnifying party to assume the defense of such claim, jointly with any other indemnifying party, with counsel reasonably satisfactory to the indemnified party; provided,
however, that any Person entitled to indemnification hereunder shall have the right to select and employ separate counsel and to participate in the defense of such claim, but the fees and expenses of such counsel shall be at the expense of
such Person unless (i) the indemnifying party has agreed in writing to pay such fees or expenses, (ii) the indemnifying party shall have failed to assume the defense of such claim within a reasonable time after receipt of notice of such
claim from the Person entitled to indemnification hereunder and employ counsel reasonably satisfactory to such Person, (iii) the indemnified party has reasonably concluded (based upon advice of its counsel) that there may be legal defenses
available to it or other indemnified parties that are different from or in addition to those available to the indemnifying party, or (iv) in the reasonable judgment of any such Person (based upon advice of its counsel) a conflict of interest
may exist between such Person and the indemnifying party with respect to such claims (in which case, if the Person notifies the indemnifying party in writing that such Person elects to employ separate counsel at the expense of the indemnifying
party, the indemnifying party shall not have the right to assume the defense of such claim on behalf of such Person). If the indemnifying party assumes the defense, the indemnifying party shall not have the right to settle such action without the
consent of the indemnified party. No indemnifying party shall consent to entry of any judgment or enter into any settlement unless such judgment or settlement (A) includes as an unconditional term thereof the giving by the claimant or plaintiff
to such indemnified party of an unconditional release from all liability in respect to such claim or litigation, (B) does not include a statement as to or an admission of fault, culpability or a failure to act, by or on behalf of any
indemnified party, and (C) does not require any action other than the payment of money by the indemnifying party. If such defense is not assumed by the indemnifying party, the indemnifying party will not be subject to any liability for any
settlement made without its prior written consent, but such consent may not be unreasonably withheld. It is understood that the indemnifying party or parties shall not, in connection with any proceeding or related proceedings in the same
jurisdiction, be liable for the reasonable fees, disbursements or other charges of more than one separate firm admitted to practice in such jurisdiction at any one time unless (x) the employment of more than one counsel has been authorized in
writing by the indemnifying party or parties, (y) an indemnified party has reasonably concluded (based on the advice of counsel) that there may be legal defenses available to it that are different from or in addition to those available to the


  
 31 









 
other indemnified parties or (z) a conflict or potential conflict exists or may exist (based upon advice of counsel to an indemnified party) between such indemnified party and the other
indemnified parties, in each of which cases the indemnifying party shall be obligated to pay the reasonable fees and expenses of such additional counsel or counsels. 
 (d) Contribution. If for any reason the indemnification provided for in paragraphs (a) and (b) of this Section 5.6 is unavailable to an indemnified party or insufficient in
respect of any Losses referred to therein, then the indemnifying party shall contribute to the amount paid or payable by the indemnified party as a result of such Loss (i) in such proportion as is appropriate to reflect the relative fault of
the indemnifying party, on the one hand, and the indemnified party or parties, on the other hand, in connection with the acts, statements or omissions that resulted in such Losses, as well as any other relevant equitable considerations. In
connection with any Registration Statement filed with the SEC by the Company, the relative fault of the indemnifying party, on the one hand, and the indemnified party, on the other hand, shall be determined by reference to, among other things,
whether any untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the indemnifying party or by the indemnified party and the parties’ relative
intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The parties hereto agree that it would not be just or equitable if contribution pursuant to this Section 5.6(d) were determined by
pro rata allocation or by any other method of allocation that does not take account of the equitable considerations referred to in the immediately preceding sentence. Notwithstanding the foregoing, no Person guilty of fraudulent
misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any Person who was not guilty of such fraudulent misrepresentation. The amount paid or payable by an indemnified party
as a result of the Losses referred to in Sections 5.6(a) and 5.6(b) shall be deemed to include, subject to the limitations set forth above, any legal or other expenses reasonably incurred by such indemnified party in connection
with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 5.6(d), in connection with any Registration Statement filed by the Company, a selling Holder of Registrable Securities shall not be
required to contribute any amount in excess of the dollar amount of the net proceeds received by such Holder under the sale of Registrable Securities giving rise to such contribution obligation. If indemnification is available under this
Section 5.6, the indemnifying parties shall indemnify each indemnified party to the full extent provided in Sections 5.6(a) and 5.6(b) without regard to the provisions of this Section 5.6(d). The remedies
provided for in this Section 5.6 are not exclusive and shall not limit any rights or remedies which may otherwise be available to any indemnified party at law or in equity. 

SECTION 5.7 Rules 144 and 144A and Regulation S. The Company covenants that, at its own expense, it will file the reports
required to be filed by it under the Securities Act and the Exchange Act and the rules and regulations adopted by the SEC thereunder. Upon the request of any Holder of Registrable Securities, the Company will deliver to such Holder a written
statement as to whether it has complied with such requirements and, if not, the specifics thereof (and such Holder shall be entitled to rely upon the accuracy of such written statement). 

SECTION 5.8 Waiver of Registration Rights. Notwithstanding anything to the contrary in this Agreement, the Carlyle
Stockholders and the Onex Stockholders, acting together in good faith, may waive compliance by the Company with any provision of this Article V, including 

  
 32 









 
waiving any obligation to include Registrable Securities in connection with any offering or Registration; provided that no such waiver shall result in any Stockholder being adversely and
disproportionately affected. 
 SECTION 5.9 Holdback Agreement. If the Company at any time shall register
Registrable Securities (including any registration pursuant to terms hereof) for sale to the public or undertake any other Public Offering in which the Company sells Common Shares for its own account, the Qualified Investor Stockholders (if any) and
the Management Stockholders will, at the request of the Company, enter into agreements with the managing underwriters, if any, in connection with any such Public Offering pursuant to which such Stockholders agree not to (i) offer, pledge, sell,
contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant for the sale of, or otherwise dispose of or Transfer any Common Shares or any securities convertible into or
exchangeable or exercisable for Common Shares, whether now owned or hereafter acquired by any such Stockholder or with respect to which any such Stockholder undersigned has or hereafter acquires the power of disposition (collectively, the
“Lock-Up Securities”) and (ii) enter into any swap or any other agreement or any transaction that Transfers, in whole or in part, directly or indirectly, the economic consequence of ownership of the Lock-Up Securities, whether
any such swap or transaction is to be settled by delivery of Common Shares or other securities, in cash or otherwise (in each case, other than those Common Shares included in such registration pursuant to this Article V) without the
prior written consent of the Company (and any managing underwriters of such Public Offering), for a period designated by the Company in writing to such Stockholders, which period shall not begin more than ten (10) days prior to the
effectiveness of the Registration Statement pursuant to which such Public Offering shall be made and shall not last more than (i) 180 days after the Effective Date, and (ii) 90 days after the effective date of any other Registration
Statement. The Company shall obtain the agreement of any Person permitted to sell shares in a Registration to be bound by and to comply with this Section 5.9 as if such Person was a Management Stockholder hereunder. 

ARTICLE VI 

RIGHT TO REPURCHASE CERTAIN SECURITIES 
 SECTION 6.1 Certain Call Rights Upon Termination of Employment. Except as otherwise agreed in writing by the Company, if the employment of any Management Stockholder with the Company or any of
its Subsidiaries terminates for any reason other than a mutually agreeable retirement (the date of such termination being referred to as the “Termination Date”), the Company shall have the right, but not the obligation, to purchase,
for cash, in one or more transactions, all or any portion of the Shares and Vested Options held by such Management Stockholder and issued pursuant to the Equity Incentive Plan of Allison Transmission Holdings, Inc., the Allison Transmission
Holdings, Inc. 2011 Equity Incentive Award Plan (or any similar equity-based plans approved by the Board of the Directors, including any shares purchased pursuant to a directed share program) (the “Equity Call Option” and such
Shares and Vested Options subject to the Equity Call Option, the “Call Equity Securities”) at the Equity Call Purchase Price. 

  
 33 









 SECTION 6.2 Procedures for Purchasing Equity Call Option. 

(a) If the Company desires to exercise the Equity Call Option, it shall deliver written notice thereof (a “Call Notice”)
to the Management Stockholder in question no later than the first anniversary of the later of (i) the Termination Date and (ii) the date of exercise of any Vested Options that constitute Call Equity Securities (the “Call
Period”), which notice shall set forth the number of and identify the Call Equity Securities of the Management Stockholder the Company desires to repurchase, the Equity Call Purchase Price for each such Call Equity Security, and the
proposed closing date of the transaction. 
 (b) All sales of Call Equity Securities to the Company pursuant to this
Article VI shall be consummated at the offices of the Company at such time specified in the Call Notice, or at such other time and/or place as the Company may otherwise agree. The delivery of certificates or other instruments evidencing
such Call Equity Securities duly endorsed for transfer (or, in the case of any Call Equity Securities that are Vested Options, accompanied by appropriate instruments of cancellation of such Vested Options) shall be made on such date against payment
of the purchase price for such Call Equity Securities. 
 (c) Notwithstanding anything in this Article VI to the
contrary, if during the Call Period, (i) any restrictions prohibit the repurchase of Call Equity Securities hereunder which the Company is otherwise entitled to make or a repurchase would not be permitted under, or would violate, applicable
law, (ii) any restrictions prohibit dividends or other transfers of funds from one or more Subsidiaries to the Company to enable such repurchases, or (iii) there exists and is continuing a default or an event of default on the part of the
Company or any Subsidiary of the Company under any bond indenture or any loan, guarantee or other agreement under which the Company or any Subsidiary of the Company has borrowed money or if the repurchase by the Company referred to in this
Article VI would result in a default or an event of default on the part of the Company or any Subsidiary of the Company under any such agreement (any such occurrence referred to in clause (i), (ii) or (iii) being an
“Event”), the Company shall be permitted to delay the repurchase of the Call Equity Securities from the Management Stockholder until the first business day which is thirty (30) calendar days after all Events have ceased to
exist. In the event of a delay due to an Event, the Call Purchase Price shall be set as of the date of the Call Notice provided in accordance with this Article VI. 
 (d) Notwithstanding the foregoing, if the Company formally elects not to effect a repurchase of the Call Equity Securities, then subject to the terms of the SCA and applicable law, the Carlyle
Stockholders and the Onex Stockholders may, but shall not be obligated to, effect such repurchases on a pro rata basis based on the number of Shares then held by the Carlyle Stockholders and the Onex Stockholders.

Director or any Affiliate thereof, as applicable, directly or indirectly, pursues or acquires such opportunity for itself, directs such opportunity to another Person, or does not present such opportunity to the Company or its Subsidiaries unless, in
the case of any such Person who is a Director, such opportunity is expressly offered to such Director in writing solely in his or her capacity as a Director.
