(2.5x) the Bain Outflows (the “G Shares Performance Threshold”). A Performance Vesting G Share shall become a Vested Security if, and only if, it has both time vested and performance vested in accordance with this paragraph.
The time vesting criteria shall be satisfied as follows: (i) 40% of the Performance Vesting G Shares shall be time vested on the second anniversary of the date of Closing and (ii) 20% of Performance Vesting G Shares shall be time vested on
each of the third, fourth and fifth anniversary of the date of Closing. A Performance Vesting G Share shall not be performance vested unless and until (i) a Change in Control or a Public Offering occurs and (ii) the G Shares Performance

(iii) Performance Vesting G Shares becoming Vested Securities, if and when such Performance Vesting G Shares become Vested

 provided that if the Catch up Amount includes securities, such securities will be subject to the transfer restrictions set out in this Agreement. 

(i) Catch up Amount Account. The Company shall retain an amount equal to the aggregate Catch up Amount to which
each Executive Securityholder is entitled pursuant to this Section 2 until such time as the Catch up Amount in respect of such Executive Securityholder’s Incentive Securities becomes payable in accordance with Section 2(h).
Upon the Executive’s Termination Date or the Investment Termination Date, the portion of the Catch up Amount attributable to Unvested Securities shall be forfeited by the Executive Securityholders and retained by the Company. The Catch up
Amount for all Executive Securityholders shall be retained in the same account.

applicable state securities laws or an exemption from such registration is available.

 (ii) no agreement exists
which would prevent the Executive from fulfilling his/her obligations under his/her employment or consultancy or business manager agreement with the Company or any of its direct or indirect subsidiaries. 

4. Restrictions on Transfer of Executive Securities. 
 (a) General Restrictions on Transfer of Executive Securities. No Executive Securityholder shall sell, transfer, assign, pledge, hypothecate or otherwise dispose of, directly or indirectly, (whether
with or without consideration and whether voluntarily or involuntarily or by operation of law) any interest in such holder’s Executive Securities (a “Transfer”) without the prior written consent of the Commandité, except
pursuant to (i) Section 4(c), (ii) Section 5 (Tag Along Rights), (iii) Section 6 (Drag Along Right); (iv) Section 8 (Right to Purchase the Executive Securities); or (v) the
Registration Rights Agreement in respect of such Executive Securityholder Vested Securities, provided that in all circumstances described in (i) to (v) any the shareholder’s guidelines adopted by the Board and in force (as amended)
from time to time are complied with on and after the Transfer. 
 (b) Indirect Transfer Restriction. No Executive
Securityholder will, without the prior written consent of the Commandité: (i) in the case of any Executive Securityholder that is (x) a Permitted Transferee of the Executive, and (y) not a natural Person, permit the issuance of
additional interests in itself or any of its Affiliates; and (ii) make any transfer of any indirect interest in any Executive Securities which, if made by the direct holder of such Executive Securities, would not be permitted by the terms of
this Agreement. 
 (c) Permitted Transfers. Notwithstanding anything to the contrary in this Agreement, the restrictions
on Transfer set forth in this Section 4 shall not apply with respect to any Transfer of Executive Securities by a holder of Executive Securities to Permitted Transferees after delivering written notice of such Permitted Transfer to the
Commandité. For the purposes of this Agreement, “Permitted Transferees” shall mean holders of Executive Securities by way of a Transfer (i) pursuant to applicable laws of descent and distribution or (ii) among the
Executive’s Family Members; provided that, the restrictions contained in this Section 4(c) will continue to be applicable to the Executive Securities after any such Transfer and any Executive Securities Transferred pursuant
to this Section 4 shall be returned to the transferor promptly upon the transferee ceasing to be Family Member of the Executive Securityholder. The Company 

  
 16 

 
hereby undertakes to give effect to any Transfer of Executive Securities which is expressly permitted by, and transferred in accordance with, this Agreement. 

(d) Transfer Procedures. Prior to transferring any Executive Securities (other than pursuant to Section 5 (Tag Along
Rights), Section 6 (Drag Along Right), Section 8 (Right to Purchase the Executive Securities) or a Public Sale) to any Person (including, for the avoidance of doubt, a Permitted Transferee), the transferring Executive
Securityholder shall cause the prospective transferee to be bound by this Agreement by executing and delivering to the Company a Deed of Adherence (in accordance with Section 4(f) below) and a Power of Attorney; provided that,
such prospective transferee may not be required to make the representations and warranties set forth in Section 3 of this Agreement. 
 (e) Transfers in Violation of Agreement. Any Transfer or attempted Transfer of any Executive Securities in violation of any provision of this Agreement shall be void and of no effect, and the
Company shall not give effect to such Transfer nor record such Transfer on its books or treat any purported transferee of such Executive Securities as the owner of such Executive Securities for any purpose. 

(f) Execution of Deed of Adherence. In the event that any Person who is not a holder of Executive Securities on the date hereof
and subsequently becomes a holder of Executive Securities through a Transfer in accordance with the terms of this Agreement, such Person shall execute and deliver a Deed of Adherence to the Company prior to such Transfer or issuance. Any Person who
has entered into a Deed of Adherence pursuant to this Agreement shall have the benefit of and be subject to the burden of all the provisions of this Agreement as if such Person was an original party hereto in the capacity designed in the Deed of
Adherence and this Agreement shall be interpreted accordingly. Nothing in this provision shall be construed as requiring any party to perform again any obligation or discharge again any liability already performed or discharged or entitle any party
to receive again any benefit already enjoyed. The Company undertakes that no Person shall be registered as a holder of Securities unless such Person has executed and delivered to the Company, on its own behalf and on behalf of all the other parties
to this Agreement, a Deed of Adherence agreeing to be bound by this Agreement. 
 (g) Termination of Restrictions. Except
as otherwise provided in Section 4(a) above and only for so long as such restrictions may continue to apply in accordance with applicable law, the restrictions set forth in this Section 4 shall continue with respect to each
Executive Security until the later of (i) the Exit Date and (ii) the date such Executive Security is listed for trading on a public securities exchange, subject to rights and obligations under the Registration Rights Agreement. 

5. Tag Along Rights. 
 (a) Delivery of Investor Sale Notice. At least thirty (30) days prior to any Transfer or series of related Transfers of Bain Securities to a third party which results in the aggregate number
of Securities held by the Bain Investors as at the date hereof being reduced by more than 20% (other than pursuant to (i) a Public Sale, (ii) any Transfer pursuant to the Registration Rights Agreement, or (iii) any Transfer to
employees, consultants or advisors (or 

  
 17 

 
any entity formed for the benefit of any of the foregoing), under a management incentive plan, each Bain Investor making such Transfer or series of Transfers (the “Transferring
Securityholder”) shall deliver a written notice (the “Bain Investor Sale Notice”) to the holders of Executive Securities, specifying in reasonable detail the identity of the prospective transferee(s), the number and types
of securities to be transferred, the price and the other terms and conditions of the Transfer, including copies of any definitive agreements. 
 (b) Election to Participate. Any holder of Executive Securities may elect to participate (a “Participating Securityholder”) in the contemplated Transfer only with respect to his
Vested Securities (“Vested Securities”) by, in each case, delivering written notice to the Transferring Securityholder within fifteen (15) days after delivery of the Bain Investor Sale Notice in accordance with
Section 19. If any holders of Vested Securities have elected to participate in such Transfer, the Transferring Securityholder and such Participating Securityholders shall be entitled to sell in the contemplated Transfer as set out below.

 (c) Pro Rata Participation. If any Executive Securityholder elects to participate in the contemplated Transfer, the
Transferring Securityholder and each Participating Securityholder shall be entitled and under an obligation to sell in the contemplated Transfer such number of Bain Securities and Vested Securities, respectively, as is equal to the product of:
(i) the quotient determined by dividing the number of Bain Securities or Vested Securities (as applicable) held by such transferring Person by the aggregate number of Securities then issued and outstanding (but excluding all Unvested
Securities); and (ii) the total number of Securities to be sold in the contemplated Transfer. The foregoing calculation shall be applied separately with respect to each type of Security. Each Participating Securityholder shall be required, to
the extent possible, to transfer all of such Participating Securityholder’s Vested Securities of the same type and in the same proportion as the Bain Securities proposed to be transferred by the Transferring Securityholder pursuant to the Bain
Investor Sale Notice. Notwithstanding the foregoing, an Executive may elect to participate in such Transfer with respect to the Executive’s Co-Invest Securities, alone or with respect to the Co-Invest Security and the Incentive Securities that
are Vested Securities. 
 (d) Consideration. The consideration per Security for any Transfer by each Participating
Securityholder pursuant to this Section 5 shall be equal to the proceeds that the Participating Securityholder would have been entitled to receive in relation his Securities if the aggregate net proceeds received in the Transfer to which
this Section 5 applied were to be paid as a liquidating distribution of the Company in accordance with the terms of this Agreement and the Articles. 
 (e) Prospective Transferees. No Transferring Securityholder shall Transfer any of its Bain Securities to any prospective transferee described in Section 5(a) unless:
(i) simultaneously with such Transfer, each such prospective transferee purchases from the Participating Securityholders the Vested Securities which the Participating Securityholders are entitled to sell to the prospective transferee pursuant
to Sections 5(b) to 5(d) (inclusive) above on terms and conditions no less favourable than those applying to the Transferring Securityholders; or (ii) if such prospective transferee declines to allow the participation of the
Participating Securityholders, simultaneously with such transfer, the Transferring Securityholder purchases (on terms and conditions no less favourable that those on which its own Securities are sold to the

  
 18 

 
transferee) the number of Vested Securities from the Participating Securityholder which such Participating Securityholder would have been entitled to sell pursuant to Sections 5(b) to 5(d)
(inclusive). If the prospective transferee fails to purchase Vested Securities from any Participating Securityholder as to which such Participating Securityholder has exercised its rights under this Section 5 and the Transferring
Securityholder fails to purchase such Vested Securities from the Participating Securityholder, the Transferring Securityholder shall not be permitted to make the proposed Transfer and any such attempted Transfer shall be subject to the penalty
provisions of Section 4(e). 
 (f) Actions. Each holder of Executive Securities transferring Securities
pursuant to this Section 5 or Section 6 below shall: 
 (i) in such Person’s
capacity as a Securityholder, be obligated (a) to provide reasonable representations and warranties, customary for Transfers of this kind, with respect to title to and ownership of such Person’s Executive Securities and such
Person’s capacity to enter into and be bound by the Transfer agreement, (b) to provide the representations and warranties, if any, to be provided by the Transferring Securityholder with respect to the Company and its Subsidiaries and their
business, (c) join on a pro rata basis (based on the amount of proceeds to be received) in any indemnification or other obligation that the Transferring Securityholder agrees to provide with respect to such representations and
warranties and (d) take all other customary, necessary or desirable actions as reasonably requested by the Transferring Securityholder in connection with the Transfer; and 

(ii) if such holder of Executive Securities shall be an Executive on the date of Transfer, in such Person’s capacity
as an Executive provide such representations and warranties, in addition to any representations and warranties provided by the Transferring Securityholder, as may be requested by the transferees; provided that, such representations and
warranties are (x) reasonable and customary, (y) consistent with current market practice at the time of the Transfer for transactions of that kind and (z) shall, at a minimum, include the representations and warranties provided in
Section 3 above. 
 (g) Costs. All costs incurred by an Executive Securityholder in connection with a
Transfer of his Executive Securities pursuant to this Section 5 which are not costs incurred for the benefit of all of the holders of the Securities being sold pursuant to such Transfer shall be borne solely by such Executive
Securityholder. In addition, such Executive Securityholder will bear (out of the proceeds of the Transfer of his Executive Securities) his pro rata share (based on the amount of consideration received by him/it pursuant to this
Section 5) of the costs of sale of such Executive Securityholder’s Executive Securities to the extent that such costs are incurred for the benefit of all of the holders of the Securities being sold pursuant to such Transfer.

 (h) Termination. The rights granted pursuant to this Section 5 shall terminate upon the termination of the
restrictions on Transfer, as set forth in Section 4(g). 

  
 19 

 6. Drag Along Right. 

(a) Approved Sale. If at any time the Bain Investors or the Board decide to effect a Sale of the Company (an “Approved
Sale”), the Bain Investors or the Board may deliver a written notice (an “Approved Sale Notice”) with respect to such proposed Approved Sale at least 10 Business Days prior to the anticipated closing date of such Approved
Sale to each Executive Securityholder with the material details of the transaction. In connection with an Approved Sale, each Executive Securityholder shall (i) raise no objections against, such sale or the process pursuant to which such sale
was arranged; (ii) waive any dissenter’s rights, appraisal rights or similar rights to such sale, if such sale is structured as a merger or consolidation; (iii) vote for and consent to any such Approved Sale; and (iv) upon
request from the Board or the Bain Investors, transfer a proportionate number of such Executive’s Executive Securities or rights to acquire Securities on the terms and conditions approved by the Board for all Securities that are the subject of
the Approved Sale. Each Executive Securityholder shall take all necessary or desirable actions in connection with the consummation of the Approved Sale as reasonably requested by the Bain Investors and the Board. If the Bain Investors do not
exercise their rights under this Section 6, any Transfer will be subject to Section 5 (Tag Along Rights). 
 (b) Distributions upon an Approved Sale. In the event of an Approved Sale, each Executive Securityholder who has been sent an Approved Sale Notice shall receive in exchange for each Vested Security
transferred, the price per Vested Security that the Executive would have been entitled to receive in relation his Vested Securities if the aggregate net proceeds received in the Transfer to which this Section 6 applied were to be paid as
a liquidating distribution of the Company in accordance with the terms of this Agreement and the Articles. To the extent any Vested Incentive Securities of the Executive Securityholder have been transferred as a result of the Executive
Securityholder having received an Approved Sale Notice (the “Dragged Vested Incentive Securities”), the Executive Securityholder will be entitled to receive on any subsequent sale of Bain Securities any amounts that he would have
received had (i) he been holding his Dragged Vested Incentive Securities at the time of any such subsequent sale and (ii) the aggregate net proceeds received in the subsequent sales been paid as a liquidating distribution of the Company in
accordance with the terms of this Agreement and the Articles. Notwithstanding anything to the contrary contained in this Section 6, any proceeds received in respect of unvested Incentive Securities pursuant to this Section 6
shall be placed by the Company Group in a reserve account. Upon any Incentive Securities becoming Vested Securities, the Company Group shall pay to each applicable Executive Securityholder the proceeds in respect of his Incentive Securities that are
then Vested Securities (if any). Any proceeds held in respect of unvested Incentive Securities shall be forfeited by the Executive Securityholder and paid to the Company Group on the earlier of the Executive’s Termination Date and the
Investment Termination Date. 
 (c) Costs. Each Executive Securityholder who sells Executive Securities pursuant to this
Section 6 will bear (out of the proceeds of sale of his Executive Securities) his pro rata share (based on the amount of consideration received by such Executive Securityholder pursuant to such Approved Sale) of the costs of sale
of such Executive Securities to the extent that such costs are incurred for the benefit of all of the holders of the Securities being sold pursuant to such Approved Sale. 

  
 20 

 (d) All Executives Securityholders who sell Executive Securities pursuant to this
Section 6 shall provide the same indemnities, representations and warranties and shall take all actions required under Section 5(f). 
 (e) Termination. The provisions of this Section 6 shall terminate upon the termination of the restrictions on Transfer set forth in Section 4(a). 

7. Public Offering. 
 (a) By the Company. If at any time the Board approves a Public Offering, each holder of Executive Securities (in his/her capacity as a Securityholder) shall vote for and consent to (to the extent
it has any voting or consent right) and raise no objections against such Public Offering and each holder of Executive Securities shall take all reasonable actions in connection with the consummation of such Public Offering as requested by the Board
and consistent with current market practice at the time of such Public Offering (including, without limitation, those actions described in Section 7(c) below but excluding, for the avoidance of doubt, any obligation for any Executive
Securityholder to execute an employment agreement or give any restrictive covenant undertakings with a greater length or scope than the Executive Securityholder is otherwise subject to). 

(b) Reorganization. In connection with any Public Offering subject to this Section 7, each holder of Executive
Securities shall agree to effectuate such Public Offering as follows: 
 (i) If the public company vehicle
(“Newco”) is to be a Luxembourg entity, the Company shall be converted into a société anonyme (public company with limited liability or S.A.) under the laws of the Grand Duchy of Luxembourg, and the shares held
by the holders will be reclassified as described below into the securities of Newco to be offered in such Public Offering (the “Newco Common”); or 

(ii) If the Board and the managing underwriters agree that it will be more beneficial to either the Bain Investors or the
Public Offering to effect the Public Offering using a Newco or a Subsidiary organized under the laws of a jurisdiction other than Luxembourg, the Company shall form or, if applicable, reorganize or recapitalize such entity, and the holders of
Executive Securities shall, if requested by the Board, contribute all of their Securities to such Newco or Subsidiary in exchange for common stock in Newco or the relevant Subsidiary. 
 The Newco Common issued to the holders of Executive Securities shall be allocated among such holders so that, immediately after such exchange, each such holder of Executive Securities holds Newco Common
having an aggregate value (based on the Public Offering price to the public) equal to the amount which such holder of the Executive Securities would have received if, immediately prior to such exchange, the Company had distributed to the
Securityholders an aggregate amount equal to the Implicit Pre-IPO Value of the Newco Common in a complete liquidation immediately prior to such exchange. Shares of Newco Common shall be allocated among such holders as determined by the rights and
preferences set out in the Articles of Association. 

  
 21 

 (c) Cooperation. Subject to the terms and conditions of this Section 7,
the Company and each holder of Executive Securities in such Person’s capacity as such, agrees that it shall assist and cooperate with the other holders of Securities and the Board in doing all things necessary, proper or advisable to consummate
and make effective, in the most expeditious manner practicable, any Public Offering and shall otherwise act in a manner conducive to maximizing the aggregate offering proceeds. Each holder of Executive Securities agrees that if he/she is an
Executive on the date of the Public Offering, such Person shall, in his/her capacity as an Executive, provide such representations and warranties as may be reasonably requested by the underwriters, in addition to any representations and warranties
provided by him/her in such Person’s capacity as a Securityholder; provided that such representations and warranties shall be (x) reasonable and customary and (y) consistent with current market practice at the time of the
Public Offering. Subject to the terms and conditions of this Section 7, Newco, the Company and its Subsidiaries and each holder of Executive Securities agrees that it shall not take any actions inconsistent with the procedures set out in
this Section 7 or that would otherwise undermine the process for a Public Offering undertaken in accordance with this Section 7. The parties agree that they may carry out or change the form of the reorganization contemplated
in Section 7(b) so as to maximize the aggregate tax efficiencies associated with such reorganization, taking into account the tax position of all the Securityholders; provided that, notwithstanding the foregoing and for the
avoidance of doubt, any such reorganization may negatively affect the tax position of individual Securityholders. Furthermore, the parties agree that, in the event that any prospective Public Offering is not consummated, and the Board shall so
elect, they will assist and cooperate with the other holders of Securities and the Board in doing all things necessary to reverse as expeditiously as reasonably practicable any reorganization of the Company and its Subsidiaries and, to the extent
reasonably practicable, to return the Company and Subsidiaries to their corporate forms and capitalization prior to any reorganization or recapitalization. 
 (d) Waiver. Without limiting the generality of the foregoing, each holder of Executive Securities hereby waives any dissenter’s rights, appraisal rights or similar rights in connection with
any recapitalization, reorganization and/or exchange pursuant to this Section 7. 
 (e) Registration Rights.
In the event that the Bain Investors become entitled to any registration rights in connection with any Public Sale, the Executive Securityholders shall, solely with respect to their Vested Securities and only to the extent consistent with applicable
law, have the right to participate in such Public Sale on a pro rata basis with the Bain Investors participating therein (the Executive “Participating Percentage”), subject to reasonable cutbacks determined by the managing
underwriters and the Registration Rights Agreement, provided that, to the extent an Executive Securityholder did not have enough Vested Securities to be able to sell his full Participating Percentage at the time of the original sale, such Executive
shall (subject to reasonable cutbacks determined by the managing underwriter) be entitled to participate on the next secondary offering also with such number of Vested Securities equal to the difference between the Executive’s Participating
Percentage and the number of Vested Securities sold by such Executive in the original sale (including any Vested Shares that were cutback from the original sale as determined by the managing underwriters). Each Executive Securityholder who elects to
participate in a Public Sale pursuant to this Section 7(e) shall enter into a Registration Rights Agreement. 

  
 22 

 8. Right to Purchase the Executive Securities 

(a) Call Option - Non-Achievement of Performance Threshold. In the event that the Performance Vesting Incentive Securities and/or
the Performance Vesting G Shares do not become Vested Securities as a result of the Performance Threshold or the G Shares Performance Threshold not being achieved by the Investment Termination Date, such Performance Vesting Incentive

of the Closing, the Company or the Bain Investors, as applicable, may purchase all or any portion of the Incentive Securities which are Vested Securities at Fair Market Value and the portion of the Incentive Securities which are Unvested Securities
at the lower of their Fair Market Value and their Original Cost in accordance with the procedures set forth in Section 8(iv). 
 (iii) Bad Leaver. If (i) the Executive’s Termination is the result of the Executive’s Termination by the Company or one of its Subsidiaries for Cause or the Executive’s

(iv) Call Option Exercise Procedures. At the Board’s discretion the Company or the Bain Investors or such
other Person as the Bain Investors may identify, as applicable, may purchase and, except as otherwise provided below, the Executive and the Executive’s Permitted Transferees shall sell all or any portion of the Executive Securities held by the
Executive and his Permitted Transferees, upon delivery, by the Company or the Bain Investors, as applicable, of a written notice (the “Call Option Exercise Notice”) to the holder or holders of the Executive Securities
(i) during the 180-day period following the Executive’s Termination Date, (ii) in the case of unvested Performance Vesting Incentive Securities, within 180 days of the Investment Termination Date or (iii) within 180 days of a
Covenant Breach (the “Call Option Exercise Period”). The Company may at any time during the Call Option Exercise Period assign its right to exercise the Call Option to the Bain Investors. The Call Option Exercise Notice will set
forth the amount of such Executive Securities to be acquired, the aggregate consideration to be paid for such Executive Securities, the Board’s determination of Fair Market Value in accordance with Section 9(a) (if any Executive
Securities are to be purchased for a price equal to Fair Market Value) and the time and place for the anticipated closing of the transaction. If any of the Executive Securities is held by Permitted Transferees, the Company or the Bain Investors, as
applicable, shall purchase the Executive Securities from such holder(s) pro rata according to the number of Executive Securities held by such holder(s) at the time of delivery of such Call Option Exercise Notice (determined as nearly as practicable
to the nearest Ordinary Share). 
 (v) Assignment Rights. If the Company or the Bain Investors (or their
assignees) shall have elected to exercise its Call Option to purchase Executive Securities, then at any time prior to the closing of such transaction, the Company or the Bain Investors (or their assignees) may resell such of the Executive Securities
as have been purchased to any employee of the Company or its subsidiaries in such amount(s) as the Board shall determine in its full discretion and the relevant employee shall have agreed to purchase. Such offer shall be effective with respect to
all or any portion of the Call Option. 
 (vi) Closing. The closing of the transactions contemplated by
Section 8(b) will take place on the date designated by the Company or the Bain Investors and in any event no later than the end of the applicable Call Option Exercise Period. The Bain Investors and/or the Company, as the case may
be, will pay for the Executive Securities to be purchased pursuant to the Call Option by (i) wire transfer of immediately available funds to the holder of such Executive Securities, in the aggregate amount equal to the purchase price for such
Executive Securities, (ii) in the case of an Executive Securityholder’s Incentive Securities only, issuing a subordinated promissory note payable at Exit in the aggregate amount equal to the purchase price of such Executive Securities or
(iii) offsetting, to the extent permitted by Section 409A of the Internal Revenue Code of 1986, as amended, any then existing documented bona fide monetary debts owed by such Executive to the Company or its subsidiaries. The Bain Investors
and/or the Company, as the case may be, shall receive from each seller regarding the sale 

  
 24 

 
of the Executive Securities to the relevant purchaser, representations and warranties that such seller has good and marketable title to the Executive Securities to be transferred, free and clear
of all liens, claims and other encumbrances and that such seller can validly enter into and be bound by the agreement of sale together with such other representations and warranties as may be reasonable and customary at the time of sale. If the
Company purchases any Executive Securities subject to the Call Option, the Executive Securities so acquired shall be redeemed in accordance with the provisions of Article 49-8 of the law of 10 August 1915 on commercial companies, as amended.

 (vii) Termination of Repurchase Right. The Call Option, and the associated rights of the Calling Person
to purchase Executive Securities pursuant to Section 8(b) shall terminate upon the date specified in Section 4(g). 
 9. Fair Market Value. 
 (a) The Fair Market Value of Executive Securities
subject to the Call Right shall be determined by the Board in its good faith discretion and, to the extent any Executive Securities are to be purchased for a price equal to Fair Market Value, included in the Call Option Exercise Notice. 

(b) Fair Market Value shall be determined as at the Executive’s Termination Date. 

10. Restricted Securities Legend. The Executive Securities have not been registered under the Securities Act and, therefore, in
addition to the other restrictions on Transfer contained in this Agreement, cannot be sold unless subsequently registered under the Securities Act or an exemption from such registration is then available. Any certificate evidencing Executive
Securities and any certificate issued in exchange for or upon the Transfer of any Executive Securities shall be stamped or otherwise imprinted with a legend in substantially the following form: 

“THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE
“ACT”), AND MAY NOT BE SOLD OR TRANSFERRED IN THE UNITED STATES OR ANY OF ITS TERRITORIES OR POSSESSIONS OR AREAS SUBJECT TO ITS JURISDICTION OR TO ANY PERSON WHO IS A NATIONAL, CITIZEN OR RESIDENT THEREOF OR PERSON NORMALLY RESIDENT
THEREIN OR TO ANY PERSON PURCHASING FOR RESALE TO ANY SUCH PERSON IN THE ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT UNDER THE ACT OR AN EXEMPTION FROM REGISTRATION THEREUNDER. IN ADDITION, THE SECURITIES REPRESENTED BY THIS CERTIFICATE ARE
SUBJECT TO THE PROVISIONS OF THE EXECUTIVE SUBSCRIPTION AND SECURITYHOLDER’S AGREEMENTS, AS AMENDED AND MODIFIED FROM TIME TO TIME, AMONG THE COMPANY AND CERTAIN SECURITYHOLDERS OF THE COMPANY AND MAY NOT BE SOLD, TRANSFERRED, PLEDGED,
HYPOTHECATED OR OTHERWISE 

  
 25 

 
DISPOSED OF EXCEPT IN ACCORDANCE THEREWITH. COPIES OF THE EXECUTIVE SUBSCRIPTION AND SECURITYHOLDER’S AGREEMENTS ARE ON FILE AT THE REGISTERED OFFICE OF THE COMPANY. THE SECURITIES MAY NOT
BE PUBLICLY OFFERED PURSUANT TO THE LAWS OF THE GRAND DUCHY OF LUXEMBOURG.” 
 The Company shall imprint such legend on certificates
evidencing Executive Securities. The legend set forth above shall be removed from the certificates evidencing any Securities of the Company which cease to be Executive Securities in accordance with the definition thereof. 

11. 83(b) Election. The Executive will make an election pursuant to Section 83(b) of the U.S. Internal Revenue Code in
respect of the Incentive Securities within 30 days following the issuance thereof to the Executive. The Incentive Securities are intended to constitute, and shall be treated for all purposes, as “profits interests” within the meaning of
Revenue Procedures 93-27 and 2001-43 and any other official guidance promulgated thereafter. 
 12. Amendment and Waiver.
Subject to Section 13, the provisions of this Agreement may be amended, modified or waived only with the prior written consent of the Company, holders of a majority of the Executive Securities and holders of a majority of the Bain
Securities, provided that no amendment of this Agreement shall be made which materially adversely affects the interests of any Executive Securityholder without such Executive Securityholder’s written consent. No course of dealing or the failure
of any party to enforce any of the provisions of this Agreement shall in any way operate as a waiver of such provisions and shall not affect the right of such party thereafter to enforce each and every provision of this Agreement in accordance with
its terms. The provisions of this Section 12 shall remain unaffected by any amendment, modification or waiver of this Agreement. 
 13. Severability. Whenever possible, each provision of this Agreement shall be interpreted in such manner as to be effective and valid under applicable law, but if any provision of this Agreement
is held to be invalid, illegal or unenforceable in any respect under any applicable law or rule in any jurisdiction, such invalidity, illegality or unenforceability shall not affect the validity, legality or enforceability of any other provision of
this Agreement in such jurisdiction or affect the validity, legality or enforceability of any provision in any other jurisdiction, but this Agreement shall be reformed, construed and enforced in such jurisdiction as if such invalid, illegal or
unenforceable provision had never been contained herein. 
 14. Restrictive Covenants. As consideration for the
opportunity to subscribe for, and purchase, the Executive Securities, the Executive agrees that he shall comply with, and be bound by, the terms and conditions of Exhibit E hereto. 

15. Entire Agreement. Except as otherwise expressly set forth herein, this Agreement and the documents referred to herein embodies
the complete agreement and understanding among the parties hereto with respect to the subject matter hereof and supersedes and preempts any prior understandings, agreements or representations by or among the parties, written or oral, which may have
related to the subject matter hereof in any way. 

  
 26 

 16. Successors and Assigns. Except as otherwise provided herein, this Agreement shall

them, so long as they hold Executive Securities, and the holders of Bain Securities and the respective permitted successors and assigns of each of them, so long as they hold Bain Securities. 

17. Counterparts. This Agreement may be executed in multiple counterparts, each of which shall be an original and all of which
taken together shall constitute one and the same agreement. 
 18. Remedies. Any person having rights under any provision
of this Agreement shall be entitled to enforce their rights under this Agreement specifically, to recover damages by reason of any breach of any provision of this Agreement and to exercise all other rights existing in their favor. The parties hereto
agree and acknowledge that money damages would not be an adequate remedy for any breach of the provisions of this Agreement and that the Company, the Commandité, any holder of Executive Securities and any holder of Bain Securities may in its,
his/her sole discretion apply for specific performance and/or injunctive relief (without posting a bond or other security) in order to enforce or prevent any violation of the provisions of this Agreement.

hereof, and (e) agrees that nothing in this Agreement shall affect the right to effect service of process in any other manner permitted by the laws of Delaware. Each party shall be responsible for its own legal fess incurred in connection with
any dispute hereunder. 
 22. Joinder. The Executive Securityholder, upon the request of the Board, will execute and
deliver either a counterpart or a joinder to any applicable securityholders agreement and/or any other agreements governing the terms of the equity interests in the Company; provided that no such agreement may provide the Executive Securityholder

equity interests represented by the Executive Securities. 
 23. Governing Law. This Agreement is governed by and

 EXHIBIT E  

RESTRICTIVE COVENANTS 
 1. TERMS. Capitalized terms not otherwise defined herein shall have the meaning set forth in the Subscription Agreement to which this Exhibit is attached. 

2. CONFIDENTIALITY. During the course of the Executive’s employment with the Company and its direct and indirect Subsidiaries
(collectively, the “Company Group”), the Executive will learn confidential information on behalf of the Company Group. The Executive agrees that the Executive shall not, directly or indirectly, use, make available, sell, disclose or
otherwise communicate to any person, other than in the course of the Executive’s assigned duties and for the benefit of the Company Group, either during the period of the Executive’s employment or at any time thereafter, any business and
technical information or trade secrets, nonpublic, proprietary or confidential information, knowledge or data relating to the Company Group, any of its subsidiaries, affiliated companies or businesses, or received from third parties subject to a
duty on the Company Group’s and its subsidiaries’ and affiliates’ part to maintain the confidentiality of such information and to use it only for certain limited purposes, in each case which shall have been obtained by the Executive
during the Executive’s employment by the Company Group (or any predecessor). The foregoing shall not apply to information that (a) was known to the public prior to its disclosure to the Executive, (b) becomes generally known to the
public subsequent to disclosure to the Executive through no wrongful act of the Executive or any representative of the Executive, or (c) the Executive is required to disclose by applicable law, regulation or legal process (provided that the
Executive provides the Company Group with prior notice of the contemplated disclosure and cooperates with the Company Group at its expense in seeking a protective order or other appropriate protection of such information). The terms and conditions
of this Agreement shall remain strictly confidential, and the Executive hereby agrees not to disclose the terms and conditions hereof to any person or entity, other than (i) to immediate family members, legal advisors or personal tax or
financial advisors, or prospective future employers solely for the purpose of disclosing the limitations on the Executive’s conduct imposed hereunder who, in each case, agree to keep such information confidential or (ii) if the Executive
is required to disclose by applicable law, regulation or legal process. 
 3. NONCOMPETITION. The Executive acknowledges
that the Executive performs services of a unique nature for the Company Group that are irreplaceable, and that the Executive’s performance of such services to a competing business will result in irreparable harm to the Company Group.
Accordingly, during the Executive’s employment and for a period of one (1) year thereafter, the Executive agrees that the Executive will not, directly or indirectly, own, manage, operate, control, be employed by (whether as an Executive,

 5. INVENTIONS. (a) The Executive

thereon. The Executive will keep full and complete written records (the “Records”), in the manner prescribed by the Company Group, of all Inventions, and will promptly disclose all Inventions completely and in writing to the Company Group.
The Records shall be the sole and exclusive property of the Company Group, and the Executive will surrender them upon termination of employment, or upon the Company Group’s request. The Executive will assign to the Company Group the Inventions
and all patents that may issue thereon in any and all countries, whether during or subsequent to the period of employment with the Company 

  
 42 

 
Group, together with the right to file, in the Executive’s name or in the name of the Company Group (or its designee), applications for patents and equivalent rights (the
“Applications”). The Executive will, at any time during and subsequent to the period of employment with the Company Group, make such applications, sign such papers, take all rightful oaths, and perform all acts as may be requested from
time to time by the Company Group with respect to the Inventions. The Executive will also execute assignments to the Company Group (or its designee) of the Applications, and give the Company Group and its attorneys all reasonable assistance
(including the giving of testimony) to obtain the Inventions for the Company Group’s benefit, all without additional compensation to the Executive from the Company Group.

Group will be the sole owner of the Inventions, and all underlying rights therein, in all media now known or hereinafter devised, throughout the universe and in perpetuity without any further obligations to the Executive. If the Inventions, or any
portion thereof, are deemed not to be Work for Hire, the Executive hereby irrevocably conveys, transfers and assigns to the Company Group, all rights, in all media now known or hereinafter devised, throughout the universe and in perpetuity, in and
to the Inventions, including, without limitation, all of the Executive’s right, title and interest in the copyrights (and all renewals, revivals and extensions thereof) to the Inventions, including, without limitation, all rights of any kind or
any nature now or hereafter recognized, including, without limitation, the unrestricted right to make modifications, adaptations and revisions to the Inventions, to exploit and allow others to exploit the Inventions and all rights to sue at law or
in equity for any infringement, or other unauthorized use or conduct in derogation of the Inventions, known or unknown, prior to the date hereof, including, without limitation, the right to receive all proceeds and damages therefrom. In addition,
the Executive hereby waives any so-called “moral rights” with respect to the Inventions. To the extent that the Executive has any rights in the results and proceeds of the Inventions that cannot be assigned in the manner described herein,
the Executive agrees to unconditionally waive the enforcement of such rights. The Executive hereby waives any and all currently existing and future monetary rights in and to the Inventions and all patents that may issue thereon, including, without
limitation, any rights that would otherwise accrue to the Executive’s benefit by virtue of the Executive being an Executive of or other service provider to the Company Group. 

7. RETURN OF COMPANY GROUP PROPERTY. On the date of the Executive’s termination of employment with the Company Group for any
reason (or at any time prior thereto at the Company Group’s request), the Executive shall return all property belonging to the Company Group or its affiliates (including, but not limited to, any Company Group-provided laptops, computers, cell
phones, wireless electronic mail devices or other equipment, or documents and property belonging to the Company Group). The Executive may retain the Executive’s rolodex and similar address books provided that such items only include contact
information. 
 8. REASONABLENESS OF COVENANTS. In signing this Agreement, the Executive gives the Company Group
assurance that the Executive has carefully read and considered all of the terms and conditions of this Agreement and the restraints imposed on the Executive’s conduct hereunder. The Executive agrees that these restraints are necessary for the

  
 43 

 
reasonable and proper protection of the Company Group and its affiliates and their trade secrets and confidential information and that each and every one of the restraints is reasonable in
respect to subject matter, length of time and geographic area, and that these restraints, individually or in the aggregate, will not prevent the Executive from obtaining other suitable employment during the period in which the Executive is bound by
the restraints. The Executive acknowledges that each of these covenants has a unique, very substantial and immeasurable value to the Company Group and its affiliates and that the Executive has sufficient assets and skills to provide a livelihood
while such covenants remain in force. The Executive further covenants that the Executive will not challenge the reasonableness or enforceability of any of the covenants set forth in this Agreement. It is also agreed that each of the Company
Group’s affiliates will have the right to enforce all of the Executive’s obligations to that affiliate under this Agreement. 
 9. AFFILIATES. For purposes of this Agreement, any reference to an “affiliate” or “affiliates” shall only apply to Bain Capital Everest Manager Holding SCA
(“Parent”) or any direct or indirectly controlled subsidiary of the Company or Parent. 
 10.
REFORMATION. If it is determined by a court of competent jurisdiction in any state that any restriction in this Agreement is excessive in duration or scope or is unreasonable or unenforceable under applicable law, it is the intention of the
parties that such restriction may be modified or amended by the court to render it enforceable to the maximum extent permitted by the laws of that state. 
 11. TOLLING. In the event of any violation of the provisions of this Agreement, the Executive acknowledges and agrees that the post-termination restrictions contained herein shall be extended by a
period of time equal to the period of such violation, it being the intention of the parties hereto that the running of the applicable post-termination restriction period shall be tolled during any period of such violation. 

12. SURVIVAL OF PROVISIONS. The obligations contained in this Agreement shall survive the termination of the Executive’s
employment with the Company Group and shall be fully enforceable thereafter. 
 13. EQUITABLE RELIEF AND OTHER REMEDIES.
The Executive acknowledges and agrees that the Company Group’s remedies at law for a breach or threatened breach of any of the provisions of this Agreement would be inadequate and, in recognition of this fact, the Executive agrees that, in
the event of such a breach or threatened breach, in addition to any remedies at law, the Company Group shall be entitled to obtain equitable relief in the form of specific performance, a temporary restraining order, a temporary or permanent
injunction or any other equitable remedy which may then be available, without the necessity of showing actual monetary damages or the posting of a bond or other security. 
 14. SEVERABILITY. To the extent that any provision of this Agreement or portion thereof shall be invalid or unenforceable, it shall be considered deleted therefrom and the remainder of such
provision and of this Agreement shall be unaffected and shall continue in full force and effect.

Note and (iii) duly executed subscription forms for the Executive Securities. Following receipt of the above, the Company effected a share capital increase and issued the relevant Executive Securities. Immediately following the issuance of the
Executive Securities, the Company entered the Executive’s name or, if applicable, the name of his nominee or custodian, on the Company’s securityholder register as the holder of the number of Securities identified to the Executive by the
Commandité pursuant to Section 2(a). 
 (d) Vesting of Incentive Securities. 

(i) Types of Vesting. Except as provided in Section 2(g), 75% of all the issued Incentive Securities will be

Section 2(f) (the “Performance Vesting Incentive Securities”). 
 (ii) Continuous
Employment. Other than as stated in clause (i) of the final paragraph of Section 2(e) below, the Time Vesting Incentive Securities shall only vest if the Executive remains in the continuous employment with the Company or any of

	 	(A)	Time Vesting Incentive Securities becoming Vested Securities, if and when such Time Vesting Incentive Securities become Vested Securities, the Company shall pay to such
Executive the Catch up Amount in respect thereof; and 

  

	 	(B)	Performance Vesting Incentive Securities becoming Vested Securities, if and when such Performance Vesting Incentive Securities become Vested Securities in accordance
with Section 2(f) below, the Company will pay to such Executive the Catch up Amount in respect thereof. 

 (iv) Catch up Amount Account. The Company shall retain an amount equal to the aggregate Catch up Amount to which each Executive holder is entitled pursuant to this Section 2 until such
time as the Catch up Amount in respect of such Executive’s Time Vesting Incentive Securities or Performance Vesting Incentive 

  
 10 

 
Securities (as applicable) becomes payable in accordance with Section 2(d)(iii). In the event any amount retained by the Company never becomes payable to the Executive hereunder, such

 Notwithstanding the foregoing, (i) if the
Executive’s Termination is a result of (A) the Executive’s death or permanent Disability, (B) a Termination of the Executive by the Company or one of its Subsidiaries without Cause, or (C) the Executive’s voluntary
resignation for Good Reason (each of (A), (B) and (C), a “Good Reason”), the Time Vesting Incentive Securities which would have become vested and become Vested Securities in the 12 months following the Termination Date had the
Executive’s employment continued for such 12 months will vest and become Vested Securities on the Termination Date, and (ii) all Time Vesting Incentive Securities shall be deemed to be 100% vested upon consummation of a Change in Control
(but excluding a Change in Control resulting from a Public Offering). 
 (f) Performance Vesting Incentive Securities.
The Performance Vesting Incentive Securities will vest and become Vested Securities upon the occurrence of either a Change in Control or a Public Offering in which the Bain Inflows immediately following such Change in Control or Public Offering (as
determined on the applicable measurement date) are at least two times (2x) the Bain Outflows (the “Performance Threshold”). 
 (g) Vesting of Class G Ordinary Shares. Notwithstanding the provisions of Sections 2(d), 2(e) and 2(f), and subject to the completion of the Redemption, all of the Class G

himself that: 
 (a) In connection with the subscription and issuance of the Executive Securities hereunder, this Agreement
constitutes the legal, valid and binding obligation of the Executive, enforceable in accordance with its terms, and the execution, delivery and performance of this Agreement by the Executive does not and will not conflict with, violate or cause a

securities laws and the Executive Securities shall not be disposed of in contravention of any applicable securities laws, and the Executive understands and acknowledges that, if applicable, United States federal and state securities laws shall
govern and restrict his/her or its right to offer, sell or otherwise dispose of any Executive Securities unless such offer, sale or disposal is registered and qualified under the Securities Act and applicable United States state securities laws, and
the Executive agrees that he/she shall not offer, sell or otherwise dispose of any Executive Securities in contravention of any applicable securities laws or in any manner which would require the Company to file any registration statement with the
United States Securities and Exchange Commission (or any similar filing under state law) or to amend or supplement any such filing or to cause the Company to violate the Securities Act, the rules and regulations promulgated thereunder or any other
United States state or federal law.

applicable state securities laws or an exemption from such registration is available.

(g) Except for the existing employment, business manager or consultancy agreements (including all amendments and supplements thereto), as
applicable between the Executive and the Company or any of its direct or indirect Subsidiaries, there are no agreements between the Executive or a Relative or Related Person, as the case may be, on the one side and

  
 12 

 
the Company or any of its direct or indirect Subsidiaries on the other side. Neither the Company nor any of its direct or indirect Subsidiaries has granted any security for the benefit of the

(ii) no agreement exists which would prevent the Executive from fulfilling his/her obligations under his/her employment or
consultancy or business manager agreement with the Company or any of its direct or indirect subsidiaries. 
 4. Restrictions
on Transfer of Executive Securities. 
 (a) General Restrictions on Transfer of Executive Securities. No Executive
shall sell, transfer, assign, pledge, hypothecate or otherwise dispose of, directly or indirectly, (whether with or without consideration and whether voluntarily or involuntarily or by operation of law) any interest in such holder’s Executive
Securities (a “Transfer”) without the prior written consent of the Commandité, except pursuant to (i) Section 4(c), (ii) Section 5 (Tag Along Rights), (iii) Section 6 (Drag
Along Right), (iv) Section 9 (Right to Purchase the Executive Securities), or (v) pursuant to the Registration Rights Agreement. 
 (b) Indirect Transfer Restriction. No Executive will, without the prior written consent of the Commandité: (i) in the case of any Executive that is (x) a Permitted Transferee of
the Executive, and (y) not a natural Person, permit the issuance of additional interests in itself or any of its Affiliates; and (ii) make any transfer of any indirect interest in any Executive Securities which, if made by the direct
holder of such Investor Securities, would not be permitted by the terms of this Agreement. 
 (c) Permitted Transfers.
Notwithstanding anything to the contrary in this Agreement, the restrictions on Transfer set forth in this Section 4 shall not apply with respect to 

  
 13 

 
any Transfer of Executive Securities by a holder of Executive Securities to Permitted Transferees after delivering written notice of such Permitted Transfer to the Commandité. For the
purposes of this Agreement, “Permitted Transferees” shall mean holders of Executive Securities by way of a Transfer (i) pursuant to applicable laws of descent and distribution or (ii) among the Executive’s Family
Members; provided that, the restrictions contained in this Section 4(c) will continue to be applicable to the Executive Securities after any such Transfer and any Executive Securities Transferred pursuant to this
Section 4 shall be returned to the transferor promptly upon the transferee ceasing to be Family Member of the Executive. The Company hereby undertakes to give effect to any Transfer of Executive Securities which is expressly permitted
by, and transferred in accordance with, this Agreement. 
 (d) Transfer Procedures. Prior to transferring any Executive
Securities (other than pursuant to Section 5 (Tag Along Rights), Section 6 (Drag Along Right), Section 9 (Right to Purchase the Executive Securities) or a Public Sale) to any Person (including, for the avoidance
of doubt, a Permitted Transferee), the transferring Executive shall cause the prospective transferee to be bound by this Agreement by executing and delivering to the Company a Deed of Adherence (in accordance with Section 4(f) below) and
a Power of Attorney; provided that, such prospective transferee may not be required to make the representations and warranties set forth in Section 3 of this Agreement. 

(e) Transfers in Violation of Agreement. Any Transfer or attempted Transfer of any Executive Securities in violation of any
provision of this Agreement shall be void and of no effect, and the Company shall not give effect to such Transfer nor record such Transfer on its books or treat any purported transferee of such Executive Securities as the owner of such Executive
Securities for any purpose. 
 (f) Execution of Deed of Adherence. In the event that any Person who is not a holder of
Executive Securities on the date hereof and subsequently becomes a holder of Executive Securities through a Transfer in accordance with the terms of this Agreement, such Person shall execute and deliver a Deed of Adherence to the Company prior to
such Transfer or issuance. Any Person who has entered into a Deed of Adherence pursuant to this Agreement shall have the benefit of and be subject to the burden of all the provisions of this Agreement as if such Person was an original party hereto
in the capacity designed in the Deed of Adherence and this Agreement shall be interpreted accordingly. Nothing in this provision shall be construed as requiring any party to perform again any obligation or discharge again any liability already
performed or discharged or entitle any party to receive again any benefit already enjoyed. The Company undertakes that no Person shall be registered as a holder of Securities unless such Person has executed and delivered to the Company, on its own
behalf and on behalf of all the other parties to this Agreement, a Deed of Adherence agreeing to be bound by this Agreement. 

(g) Termination of Restrictions. Except as otherwise provided in Section 4(a) above and only for so long as such
restrictions may continue to apply in accordance with applicable law, the restrictions set forth in this Section 4 shall continue with respect to each Executive Security until the occurrence of a Public Offering.

 5. Tag Along Rights. 

(a) Delivery of Investor Sale Notice. At least thirty (30) days prior to any Transfer or series of related Transfers of Bain
Securities to a third party which results in the aggregate number of Securities held by the Bain Investors as at the date hereof being reduced by more than 20% (other than pursuant to (i) a Public Sale, (ii) any Transfer pursuant to the
Registration Rights Agreement, or (iv) any Transfer to employees, consultants or advisors (or any entity formed for the benefit of any of the foregoing), under a management incentive plan, each Bain Investor making such Transfer or series of
Transfers (the “Transferring Securityholder”) shall deliver a written notice (the “Bain Investor Sale Notice”) to the holders of Executive Securities, specifying in reasonable detail the identity of the prospective
transferee(s), the number and types of securities to be transferred, the price and the other terms and conditions of the Transfer, including copies of any definitive agreements. 

(b) Election to Participate. Any holder of Executive Securities may elect to participate (a “Participating
Securityholder”) in the contemplated Transfer only with respect to his Vested Securities by delivering written notice to the Transferring Securityholder within fifteen (15) days after delivery of the Bain Investor Sale Notice in
accordance with Section 19. If any holders of Executive Securities have elected to participate in such Transfer, the Transferring Securityholder and such Participating Securityholders shall be entitled to sell in the contemplated
Transfer as set out below. 
 (c) Pro Rata Participation. If any Executive elects to participate in the contemplated
Transfer, the Transferring Securityholder and each Participating Securityholder shall be entitled and under an obligation to sell in the contemplated Transfer such number of Bain Securities and Vested Securities, respectively, as is equal to the
product of: (i) the quotient determined by dividing the number of Bain Securities or Vested Securities (as applicable) held by such transferring Person by the aggregate number of Securities then issued and outstanding (but excluding all
Unvested Securities); and (ii) the total number of Securities to be sold in the contemplated Transfer. The foregoing calculation shall be applied separately with respect to each type of Security. Each Participating Securityholder shall be
required, to the extent possible, to transfer all of such Participating Securityholder’s Vested Securities of the same type and in the same proportion as the Bain Securities proposed to be transferred by the Transferring Securityholder pursuant
to the Bain Investor Sale Notice. Notwithstanding the foregoing, an Executive may elect to participate in such Transfer only with respect to the Executive’s Co-Invest Securities and not the Executive’s Incentive Securities. 

(d) Consideration. The consideration per Security for any Transfer by each Participating Securityholder pursuant to this
Section 5 shall be equal to the proceeds that the Participating Securityholder would have been entitled to receive in relation his Securities if the aggregate net proceeds received in the Transfer to which this Section 5 applied
were to be paid as a liquidating distribution of the Company in accordance with the terms of this Agreement and the Articles. 

(e) Prospective Transferees. No Transferring Securityholder shall Transfer any of its Bain Securities to any prospective
transferee described in Section 5(a) unless: (i) simultaneously with such Transfer, each such prospective transferee purchases from the 

  
 15 

 
Participating Securityholders the Vested Securities which the Participating Securityholders are entitled to sell to the prospective transferee pursuant to Sections 5(b) to 5(d) (inclusive)
above on terms and conditions no less favourable than those applying to the Transferring Securityholders; or (ii) if such prospective transferee declines to allow the participation of the Participating Securityholders, simultaneously with such
transfer, the Transferring Securityholder purchases (on terms and conditions no less favourable that those on which its own Securities are sold to the transferee) the number of Vested Securities from the Participating Securityholder which such
Participating Securityholder would have been entitled to sell pursuant to Sections 5(b) to 5(d) (inclusive). If the prospective transferee fails to purchase Vested Securities from any Participating Securityholder as to which such
Participating Securityholder has exercised its rights under this Section 5 and the Transferring Securityholder fails to purchase such Vested Securities from the Participating Securityholder, the Transferring Securityholder shall not be
permitted to make the proposed Transfer and any such attempted Transfer shall be subject to the penalty provisions of Section 4(e). 
 (f) Actions. Each holder of Executive Securities transferring Securities pursuant to this Section 5 or Section 6 below shall: 

(i) in such Person’s capacity as a Securityholder, be obligated (a) to provide reasonable representations and
warranties, customary for Transfers of this kind, with respect to title to and ownership of such Person’s Executive Securities and such Person’s capacity to enter into and be bound by the Transfer agreement, (b) to provide the
representations and warranties, if any, to be provided by the Transferring Securityholder with respect to the Company and its Subsidiaries and their business, (c) join on a pro rata basis (based on the amount of proceeds to be received)
in any indemnification or other obligation that the Transferring Securityholder agrees to provide with respect to such representations and warranties and (d) take all other customary, necessary or desirable actions as reasonably requested by
the Transferring Securityholder in connection with the Transfer; and 
 (ii) if such holder of Executive
Securities shall be an Executive on the date of Transfer, in such Person’s capacity as an Executive provide such representations and warranties, in addition to any representations and warranties provided by the Transferring Securityholder, as
may be requested by the transferees; provided that, such representations and warranties are (x) reasonable and customary, (y) consistent with current market practice at the time of the Transfer for transactions of that kind and
(z) shall, at a minimum, include the representations and warranties provided in Section 3 above. 
 (g)
Costs. All costs incurred by an Executive in connection with a Transfer of his/her Executive Securities pursuant to this Section 5 shall be borne solely such Executive. In addition, such Executive will bear its pro rata
share (based on the amount of consideration received by him/it pursuant to this Section 5) of the costs of sale of such Executive’s Executive Securities to the extent that such costs are incurred for the benefit of all of the
holders of the Securities being sold pursuant to such Transfer. 

  
 16 

 (h) Termination. The rights granted pursuant to this Section 5 shall
terminate upon the termination of the restrictions on Transfer set forth in Section 4(a). 
 6. Drag Along
Right. 
 (a) Approved Sale. If at any time the Bain Investors or the Board decide to effect a Sale of the Company
(an “Approved Sale”), the Bain Investors or the Board may deliver a written notice (an “Approved Sale Notice”) with respect to such proposed Approved Sale at least 10 Business Days prior to the anticipated closing
date of such Approved Sale to each Executive with the material details of the transaction. In connection with an Approved Sale, each Executive shall (i) conduct itself in a manner conducive to maximizing the aggregate sale proceeds,
(ii) raise no objections against, such sale or the process pursuant to which such sale was arranged; (iii) waive any dissenter’s rights, appraisal rights or similar rights to such sale, if such sale is structured as a merger or
consolidation; (iv) vote for and consent to any such Approved Sale; and (v) upon request from the Board or the Bain Investors, transfer a proportionate number of such Executive’s Executive Securities or rights to acquire Securities on
the terms and conditions approved by the Board. Each Executive shall take all necessary or desirable actions in connection with the consummation of the Approved Sale as reasonably requested by the Bain Investors and the Board. If the Bain Investors
do not exercise their rights under this Section 6, any Transfer will be subject to Section 5 (Tag Along Rights). 
 (b) Distributions upon an Approved Sale. In the event of an Approved Sale, each Executive who has been sent an Approved Sale Notice shall receive in exchange for each Vested Security transferred,
the price per Vested Security that the Executive would have been entitled to receive in relation his Vested Securities if the aggregate net proceeds received in the Transfer to which this Section 6 applied were to be paid as a liquidating
distribution of the Company in accordance with the terms of this Agreement and the Articles. To the extent any Vested Incentive Securities of the Executive have been transferred as a result of the Executive having received an Approved Sale Notice
(the “Dragged Vested Incentive Securities”), the Executive will be entitled to receive on any subsequent sale of Bain Securities any amounts that he would have received had (i) he been holding his Dragged Vested Incentive
Securities at the time of any such subsequent sale and (ii) the aggregate net proceeds received in the subsequent sales been paid as a liquidating distribution of the Company in accordance with the terms of this Agreement and the Articles.

 (c) Costs. Each Executive who sells Executive Securities pursuant to this Section 6 will bear their pro
rata share (based on the amount of consideration received by such Executive pursuant to such Approved Sale) of the costs of sale of such Executive Securities to the extent that such costs are incurred for the benefit of all of the holders of the
Securities being sold pursuant to such Approved Sale. 
 (d) All Executives who sell Executive Securities pursuant to this
Section 6 shall provide the same indemnities, representations and warranties and shall take all actions required under Section 5(f). 
 (e) Termination. The provisions of this Section 6 shall terminate upon the termination of the restrictions on Transfer set forth in Section 4(a). 

  
 17 

 7. Public Offering. 

(a) By the Company. If at any time the Board approves a Public Offering, each holder of Executive Securities (in his/her capacity
as a Securityholder) shall vote for and consent to (to the extent it has any voting or consent right) and raise no objections against such Public Offering and each holder of Executive Securities shall take all reasonable actions in connection with
the consummation of such Public Offering as requested by the Board and consistent with current market practice at the time of such Public Offering (including, without limitation, those actions described in Section 7(c) below).

 (b) Reorganization. In connection with any Public Offering subject to this Section 7, each holder of
Executive Securities shall agree to effectuate such Public Offering as follows: 
 (i) If the public company
vehicle (“Newco”) is to be a Luxembourg entity, the Company shall be converted into a société anonyme (public company with limited liability or S.A.) under the laws of the Grand Duchy of Luxembourg, and the
shares held by the holders will be reclassified as described below into the securities of Newco to be offered in such Public Offering (the “Newco Common”); or 

(ii) If the Board and the managing underwriters agree that it will be more beneficial to either the Bain Investors or the
Public Offering to effect the Public Offering using a Newco or a Subsidiary organized under the laws of a jurisdiction other than Luxembourg, the Company shall form or, if applicable, reorganize or recapitalize such entity, and the holders of
Executive Securities shall, if requested by the Board, contribute all of their Securities to such Newco or Subsidiary in exchange for common stock in Newco or the relevant Subsidiary. 
 The Newco Common issued to the holders of Executive Securities shall be allocated among such holders so that, immediately after such exchange, each such holder of Executive Securities holds Newco Common
having an aggregate value (based on the Public Offering price to the public) equal to the amount which such holder of the Executive Securities would have received if, immediately prior to such exchange, the Company had distributed to the
Securityholders an aggregate amount equal to the Implicit Pre-IPO Value of the Newco Common in a complete liquidation immediately prior to such exchange. Shares of Newco Common shall be allocated among such holders as determined by the rights and
preferences set out in the Articles of Association. 
 (c) Cooperation. Subject to the terms and conditions of this
Section 7, the Company and each holder of Executive Securities in such Person’s capacity as such, agrees that it shall assist and cooperate with the other holders of Securities and the Board in doing all things necessary, proper or
advisable to consummate and make effective, in the most expeditious manner practicable, any Public Offering and shall otherwise act in a manner conducive to maximizing the aggregate offering proceeds. Each holder of Executive Securities agrees that
if he/she is an Executive on the date of the Public Offering, such Person shall, in his/her capacity as an Executive, provide such representations and warranties as may be reasonably requested by the underwriters, in addition to any representations
and warranties provided by him/her in such 

  
 18 

 
Person’s capacity as a Securityholder; provided that such representations and warranties shall be (x) reasonable and customary and (y) consistent with current market
practice at the time of the Public Offering. Subject to the terms and conditions of this Section 7, Newco, the Company and its Subsidiaries and each holder of Executive Securities agrees that it shall not take any actions inconsistent
with the procedures set out in this Section 7 or that would otherwise undermine the process for a Public Offering undertaken in accordance with this Section 7. The parties agree that they may carry out or change the form of
the reorganization contemplated in Section 7(b) so as to maximize the aggregate tax efficiencies associated with such reorganization, taking into account the tax position of all the Securityholders; provided that, notwithstanding
the foregoing and for the avoidance of doubt, any such reorganization may negatively affect the tax position of individual Securityholders. Furthermore, the parties agree that, in the event that any prospective Public Offering is not consummated,
and the Board shall so elect, they will assist and cooperate with the other holders of Securities and the Board in doing all things necessary to reverse as expeditiously as reasonably practicable any reorganization of the Company and its
Subsidiaries and, to the extent reasonably practicable, to return the Company and Subsidiaries to their corporate forms and capitalization prior to any reorganization or recapitalization. 

(d) Waiver. Without limiting the generality of the foregoing, each holder of Executive Securities hereby waives any
dissenter’s rights, appraisal rights or similar rights in connection with any recapitalization, reorganization and/or exchange pursuant to this Section 7. 
 (e) Registration Rights Agreement. In connection with any Public Offering, Newco and the Executive Securityholders shall enter into a Registration Rights Agreement which shall be consistent with
the terms of this Section 7 and in a form and substance satisfactory to the Board. For the avoidance of doubt, in the event that the Bain Investors become entitled to any registration rights in connection with a Public Offering, the
Executives shall, to the extent consistent with applicable law, have the right to participate on a pro rata basis on all registrations, listings and qualifications made by the Company of its Bain Securities, subject to any reasonable cutbacks
determined by the managing underwriter. 
 8. “Material Covenant Violation” or a “Material Cooperation
Violation”. 
 In the event of a Material Covenant Violation or a Material Cooperation Violation (each, as defined in
the Employment Agreement), (i) any Incentive Securities which have not at the time of such Material Covenant Violation or a Material Cooperation Violation (the “MCV Date”) become Vested Securities and (ii) any Incentive
Securities that became Vested Securities in the preceding 6-month period ((i) and (ii) together, the “MCV Securities”) may be purchased by the Company or the Bain Investors or such other Person as the Bain Investors may
identify, at the lower of Fair Market Value and their Original Cost in accordance with the procedures set forth below in Section 9(b)(iv). 
 9. Right to Purchase the Incentive Securities 
 (a) Call Option -
Non-Achievement of Performance Threshold. In the event that the Performance Vesting Incentive Securities do not become Vested Securities as a result of the Performance Threshold not being achieved upon a Change in Control or Public Offering in
accordance with Section 2(f), such Performance Vesting Incentive Securities may be purchased the Company or the Bain Investors or such other Person as the Bain Investors may identify, at

  
 19 

 
the lower of Fair Market Value and their Original Cost in accordance with the procedure set forth in Section 9(b)(iv). 

(b) Call Option. In the event of the Executive’s ceases to be employed by the Company or any of its Subsidiaries, the
Incentive Securities then held by the Executive (or his Permitted Transferees, as applicable) may be purchased the Company or the Bain Investors or such other Person as the Bain Investors may identify, in accordance with the procedure set forth in
Section 9(b)(iv) (the “Call Option”). 
 (i) Good Leaver. If the Executive
is a Good Leaver, then at any time on or after the Executive’s Termination Date, the Company or the Bain Investors, as applicable, may purchase all or any portion of the Incentive Securities which are Vested Securities at Fair Market Value and,
subject to the proviso below in this Section 9(b)(i), the entire portion of the Incentive Securities which are Unvested Securities at the lower of their Fair Market Value and their Original Cost in accordance with the procedures set
forth in Section 9(iv), provided that, the Executive (or any of his Permitted Transferees, if applicable) shall be permitted for a period of 12 months from the Executive’s Termination Date (the “Post Termination
Period”) to retain any of the Unvested Performance Vesting Incentive Securities (the “Unvested Post-Termination Securities”). If during the Post Termination Period, the Performance Threshold is achieved in connection with a
Change in Control or Public Offering, the Unvested Post-Termination Securities shall become Vested Securities (and shall, for the avoidance of doubt, be treated as Vested Securities for all purposes of this Agreement). If, however, the Performance
Threshold is not achieved during the Post Termination Period, after the expiration of such period, the Unvested Post-Termination Securities shall no longer be capable of vesting and may be purchased at the lower of their Fair Market Value and their
Original Cost in accordance with the procedures set forth in Section 9(iv). 
 (ii) Medium
Leaver. If an Executive’s Termination is the result of the Executive’s voluntary resignation without Good Reason, then on or after the Executive’s Termination Date, the Company or the Bain Investors, as applicable, may purchase
all or any portion of the Incentive Securities which are Vested Securities at Fair Market Value and the entire portion of the Incentive Securities which are Unvested Securities at the lower of their Fair Market Value and their Original Cost in
accordance with the procedures set forth below. 
 (iii) Bad Leaver. If the Executive’s Termination
is the result of the Executive’s Termination by the Company or one of its Subsidiaries occurring for Cause, then on or after the Executive’s Termination Date, the Company or the Bain Investors, as applicable, may purchase all of the
Incentive Securities (including both Vested Securities and Unvested Securities) at the lower of Fair Market Value and their Original Cost in accordance with the procedures set forth below. 

(iv) Call Option Exercise Procedures. At the Board’s discretion the Company or the Bain Investors or such
other Person as the Bain Investors may identify, as applicable, may purchase and, except as otherwise provided below, the Executive and the Executive’s Permitted Transferees shall sell all or any portion of the Incentive

  
 20 

 
Securities held by the Executive and his Permitted Transferees, upon delivery, by the Company or the Bain Investors, as applicable, of a written notice (the “Call Option Exercise
Notice”) to the holder or holders of the Incentive Securities (i) during the 180-day period following the Executive’s Termination Date, (ii) with respect to Unvested Post-Termination Securities during the 180-day period
commencing on the earlier of the date such Securities vest and the expiration of the Post Termination Period, (iii) during the 180 day period following a Change in Control or Public Offering, in relation to any Performance Vesting Incentive

rata according to the number of Incentive Securities held by such holder(s) at the time of delivery of such Call Option Exercise Notice (determined as nearly as practicable to the nearest Ordinary Share). 

(v) Assignment Rights. If the Company or the Bain Investors (or their assignees) shall have elected to exercise
its Call Option to purchase Incentive Securities, then at any time prior to the closing of such transaction, the Company or the Bain Investors (or their assignees) may resell such of the Incentive Securities as have been purchased to any
Executive(s) in such amount(s) as the Board shall determine in its full discretion and the relevant Executive shall have agreed to purchase. Such offer shall be effective with respect to all or any portion of the Call Option. 

(vi) Closing. The closing of the transactions contemplated by Section 9(b) will take place on the date
designated by the Company or the Bain Investors and in any event no later than the later of (a) the 180th day following the Termination Date or following vesting in relation to any Unvested Post-Termination Securities that have become Vested
Securities in accordance with Section 9(b)(i) above or following the end of the Post-Termination Period in relation to any Unvested Post-Termination Securities that have not become Vested Securities or following a Change in Control or
Public Offering, in relation to any Performance Vesting Incentive Securities which have not become Vested Securities under Section 2(f), or following the MCV Date in relation to the MCV Securities and (b) the 10th day
following the determination of the Fair Market Value in accordance with Section 10. The Bain Investors and/or the Company, as the case may be, will pay for the Incentive Securities to be purchased pursuant to the Call Option by wire
transfer of immediately available funds to the holder of such Incentive Securities, in the aggregate amount equal to the purchase price for such Incentive Securities, The Bain Investors and/or the Company, as the case may be, shall receive from each
seller regarding the sale of the Incentive Securities to the relevant purchaser, representations and warranties that such seller has good and marketable title to the 

  
 21 

 Incentive Securities to be transferred, free and clear of all liens, claims and other
encumbrances and that such seller can validly enter into and be bound by the agreement of sale together with such other representations and warranties as may be reasonable and customary at the time of sale. If the Company purchases any Incentive
Securities subject to the Call Option, the Incentive Securities so acquired shall be redeemed in accordance with the provisions of Article 49-8 of the law of 10 August 1915 on commercial companies, as amended. 

(vii) Termination of Repurchase Right. The Call Option, and the associated rights of the Calling Person to purchase
Executive Securities pursuant to Section 9(b) shall terminate upon the completion of a Public Sale or a Sale of the Company. 
 10. Fair Market Value. 
 (a) The Fair Market Value of Incentive Securities
subject to the Call Right shall be determined by the Board in its good faith discretion and, to the extent any Incentive Securities are to be purchased for a price equal to Fair Market Value, included in the Call Option Exercise Notice, but shall be
subject to adjustment in accordance with Section 10. 
 (b) Fair Market Value shall be determined as at the
Executive’s Termination Date. 
 (c) Within 30 days starting on the day after receipt of the Call Option Exercise Notice,
the Executive shall notify the Board in writing if the Executive does not agree with the Board’s calculation of Fair Market Value (a “Disagreement Notice”). 

(d) If the Executive does not provide the Board with a Disagreement Notice within the 30-day period referred to in
Section 10(c), the calculation of the Fair Market Value provided by the Board shall be final and binding and shall constitute the Fair Market Value. If the Executive provides the Board with a Disagreement Notice within the 30-day period
referred to in Section 10(c), the Executive may appoint a nationally recognised firm experienced in the valuation of private companies to determine the Fair Market Value (the “Executive Valuator”). The Company shall
promptly provide all data reasonably requested by the Executive Valuator (including but not limited to financial data) which the Executive Valuator determines in good faith is necessary in order for it to determine Fair Market Value. 

(e) If, within 60 days starting on the day after receipt of the Disagreement Notice (or such longer period as may be agreed by the
Executive and the Board), the Executive (being advised by the Executive Valuator) and the Board have not agreed to the Fair Market Value, the Executive and the Board shall refer the matters in dispute to a nationally recognised independent firm of
accountants agreed by the parties in writing. If the Executive and the Board are unable to agree on the appointment of an independent firm of accountants after a further 21 days, an independent firm of accountants will be appointed on the
application of either party to the President at that time of the American Institute of Certified Public Accountants (the “Independent Valuator”) for the purposes of determining the Fair Market Value which shall be

  
 22 

 either the number originally included in the Call Option Exercise Notice or the number submitted by the
Executive to the Independent Valuator. 
 (f) If the final Fair Market Value, as determined pursuant to the process described
above, is 110% or more of the Fair Market Value originally determined by the Board and included in the Call Option Exercise Notice, then the Company will pay the cost of the Executive Valuator and, if applicable, the Independent Valuator, and if
such final Fair Market Value is less than 110% of the Fair Market Value originally determined by the Board, then the Executive will pay the cost of the Executive Valuator and, if applicable, the Independent Valuator. Notwithstanding the above, in
choosing the Independent Valuator, if applicable, the Board and the Executive shall take into account the cost thereof, with a view of retaining a firm which charges not more than $200,000 for such valuation. 

11. Restricted Securities Legend. The Executive Securities have not been registered under the Securities Act and, therefore, in
addition to the other restrictions on Transfer contained in this Agreement, cannot be sold unless subsequently registered under the Securities Act or an exemption from such registration is then available. Any certificate evidencing Executive
Securities and any certificate issued in exchange for or upon the Transfer of any Executive Securities shall be stamped or otherwise imprinted with a legend in substantially the following form: 

“THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE
“ACT”), AND MAY NOT BE SOLD OR TRANSFERRED IN THE UNITED STATES OR ANY OF ITS TERRITORIES OR POSSESSIONS OR AREAS SUBJECT TO ITS JURISDICTION OR TO ANY PERSON WHO IS A NATIONAL, CITIZEN OR RESIDENT THEREOF OR PERSON NORMALLY RESIDENT
THEREIN OR TO ANY PERSON PURCHASING FOR RESALE TO ANY SUCH PERSON IN THE ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT UNDER THE ACT OR AN EXEMPTION FROM REGISTRATION THEREUNDER. IN ADDITION, THE SECURITIES REPRESENTED BY THIS CERTIFICATE ARE
SUBJECT TO THE PROVISIONS OF THE EXECUTIVE SUBSCRIPTION AND SECURITYHOLDER’S AGREEMENTS, AS AMENDED AND MODIFIED FROM TIME TO TIME, AMONG THE COMPANY AND CERTAIN SECURITYHOLDERS OF THE COMPANY AND MAY NOT BE SOLD, TRANSFERRED, PLEDGED,
HYPOTHECATED OR OTHERWISE DISPOSED OF EXCEPT IN ACCORDANCE THEREWITH. COPIES OF THE EXECUTIVE SUBSCRIPTION AND SECURITYHOLDER’S AGREEMENTS ARE ON FILE AT THE REGISTERED OFFICE OF THE COMPANY. THE SECURITIES MAY NOT BE PUBLICLY OFFERED PURSUANT
TO THE LAWS OF THE GRAND DUCHY OF LUXEMBOURG.” 
 The Company shall imprint such legend on certificates evidencing Executive Securities.
The legend set forth above shall be removed from the certificates evidencing any Securities of the Company which cease to be Executive Securities in accordance with the definition thereof. 

  
 23 

 12. 83(b) Election. The Executive will make an election pursuant to
Section 83(b) of the U.S. Internal Revenue Code in respect of the Incentive Securities within 30 days following the issuance thereof to the Executive. The Incentive Securities are intended to constitute, and shall be treated for all purposes,
as “profits interests” within the meaning of Revenue Procedures 93-27 and 2001-43 and any other official guidance promulgated thereafter. 
 13. Amendment and Waiver. Subject to Section 14, the provisions of this Agreement may be amended, modified or waived only with the prior written consent of the Company, holders of a
majority of the Executive Securities and holders of a majority of the Bain Securities. No course of dealing or the failure of any party to enforce any of the provisions of this Agreement shall in any way operate as a waiver of such provisions and
shall not affect the right of such party thereafter to enforce each and every provision of this Agreement in accordance with its terms. The provisions of this Section 12 shall remain unaffected by any amendment, modification or waiver of
this Agreement. 
 14. Severability. Whenever possible, each provision of this Agreement shall be interpreted in such
manner as to be effective and valid under applicable law, but if any provision of this Agreement is held to be invalid, illegal or unenforceable in any respect under any applicable law or rule in any jurisdiction, such invalidity, illegality or
unenforceability shall not affect the validity, legality or enforceability of any other provision of this Agreement in such jurisdiction or affect the validity, legality or enforceability of any provision in any other jurisdiction, but this
Agreement shall be reformed, construed and enforced in such jurisdiction as if such invalid, illegal or unenforceable provision had never been contained herein. 
 15. Entire Agreement. Except as otherwise expressly set forth herein, this Agreement and the documents referred to herein embodies the complete agreement and understanding among the parties hereto
with respect to the subject matter hereof and supersedes and preempts any prior understandings, agreements or representations by or among the parties, written or oral, which may have related to the subject matter hereof in any way.

 18. Remedies. Any person having rights under any provision of this Agreement shall be entitled to enforce their rights
under this Agreement specifically, to recover damages by reason of any breach of any provision of this Agreement and to exercise all other rights existing in their favor. The parties hereto agree and acknowledge that money damages would not be an
adequate remedy for any breach of the provisions of this Agreement and that the Company, the Commandite, any holder of Executive Securities and any holder of Bain Securities may in its, 

  
 24
