 Section 1.3 Other Definitional and Interpretation Provisions. 

(a) The words “hereof,” “herein” and “hereunder” and words of similar import when used in this Agreement shall
refer to this Agreement as a whole and not to any particular provision of this Agreement, and Article and Section references are to this Agreement unless otherwise specified. Whenever the words “include,” “includes” or

 (b) The
meanings given to terms defined herein shall be equally applicable to both the singular and plural forms of such terms. 
 (c) [Reserved].

 (d) Notwithstanding anything herein to the contrary, when one Stockholder (the “Parent Stockholder”) indirectly
holds an economic or beneficial interest in Shares through another Stockholder that directly holds the Shares (the “Record Holder Stockholder”) then: 

(i) The number of Shares deemed Beneficially Owned by the Parent Stockholder will be deemed to be equal to the number of Shares
that would be distributed to such Parent Stockholder if the Record Holder Stockholder (and any intermediate holding entities) were to distribute all of the Shares held by such Record Holder Stockholder to such Record Holder Stockholder’s (and
any such intermediate holding entities’) holders of Equity Securities; 
 (ii) Subject to the proviso in the definition
of “Transfer,” any direct or indirect (including by issuance of Equity Securities), sale, transfer, assignment, pledge, encumbrance, hypothecation, or similar disposition (by operation of law or otherwise), either voluntarily or
involuntarily, of Equity Securities of such Parent Stockholder, or the entry into any contract, option or other arrangement or other understanding with respect to any of the foregoing, shall be deemed to be a Transfer of a proportionate number of
Shares held by the relevant Record Holder Stockholder;

Article V, as applicable; and (B) be considered the Financial Investor (if applicable) and entitled to exercise the rights of a Financial Investor pursuant to Article X (subject to the right of such Financial Investor to assign
its actual right to purchase to its Parent Stockholder(s)); and 
 (iv) In the event of any Transfer as a result of the
application of Section 1.3(d)(ii) above, the Eligible Tag-Along Stockholders pursuant to Section 4.4 will have the right to directly Transfer Shares in such
transaction solely to the extent such Eligible Tag-Along Stockholders would have such right with respect to a direct Transfer to such transferee by the Record Holder Stockholder of the same number of Shares
deemed transferred pursuant to Section 1.3(d)(ii). 

  
 18 

 ARTICLE II 

CORPORATE GOVERNANCE 
 
Section 2.1 Boards of Directors. 
 (a) [Reserved]. 

(b) [Reserved]. 
 (c)
Board Representation. Unless both Sponsors otherwise agree in writing: 
 (i) The Carlyle Entities will have the right
to nominate a number of individuals for election to the Company Board equal to the Carlyle Board Representation Number (with each of such individuals being nominated by the Carlyle Sponsor and/or such other Carlyle Entities as the Carlyle Sponsor
shall from time to time designate in writing to the Company) (each, a “Carlyle Nominee”) and the H&F Entities will have the right to nominate a number of individuals for election to the Company Board equal to the H&F
Board Representation Number (with each of such individuals being nominated by the H&F Sponsors and/or such other H&F Entities as the H&F Sponsors shall from time to time designate in writing to the Company) (each, an “H&F
Nominee”). 
 (ii) For so long as the Carlyle Entities or the H&F Entities have the right to nominate any
Carlyle Nominee or any H&F Nominee, respectively, in connection with each election of Directors, (A) the Company shall nominate each such Carlyle Nominee or H&F Nominee, as the case may be, for election as a Director as part of the
slate that is included in the proxy statement (or consent solicitation or similar document) of the Company relating to the election of Directors, and shall provide the highest level of support for the election of each such Carlyle Nominee or H&F
Nominee, as the case may be, as it provides to any other individual standing for election as a Director as part of the Company’s slate of Directors, and the Company Board shall recommend that the stockholders of the Company elect to the Company
Board each such Carlyle Nominee or H&F Nominee, and (B) the Company shall include in the slate that is included in the proxy statement (or consent solicitation or similar document) of the Company relating to the election of Directors only
(1) the H&F Nominees nominated by the H&F Entities in accordance with this Section 2.1, (2) the Carlyle Nominees nominated by the Carlyle Entities in accordance with this Section 2.1
and (3) the other Director nominees (if any) nominated by the Company Board (or a committee thereof), provided that each of such other Director nominees shall be (A) an Independent Director unanimously approved by the Carlyle
Entities (but only if the Carlyle Entities then have a right to nominate a Carlyle Nominee) and the H&F Entities (but only if the H&F Entities then have a right to nominate an H&F Nominee) (in each case, such approval not unreasonably to
be withheld) or (B) the individual then serving as the chief executive officer of the Company. For so long as the Carlyle Entities or the H&F Entities have the right to nominate any Carlyle Nominee or any H&F Nominee, respectively, the
Company Board (and any committee thereof) shall not nominate (and the Company shall not include in the slate that is included in the proxy statement (or consent solicitation or similar document) of the Company relating to the election of Directors)
a number of nominees for any election of Directors that exceeds nine (9) Directors, and the size of the Company Board shall not exceed nine (9) Directors, unless the Carlyle Entities (but only if the Carlyle Entities then have a right to
nominate a Carlyle Nominee) and the H&F Entities (but only if the H&F Entities then have a right to nominate an H&F Nominee) have otherwise agreed in writing. For so long as the Company’s certificate of incorporation shall provide
for the division of directors into three classes, the Company Board shall determine which director class each director shall serve and shall apportion such nominees among the classes so as to maintain the number of Carlyle Nominees and H&F
Director Nominees in each class as nearly equal as possible. 

  
 19 

 (iii) If, from time to time, the Carlyle Board Representation Number or the
H&F Board Representation Number shall decrease, the Carlyle Entities or the H&F Entities, as applicable, and the Company shall take all necessary action to cause the applicable number of Carlyle Nominees or H&F Nominees, as applicable,
to resign or be removed immediately. Subject to the immediately foregoing sentence, in the event that a Carlyle Nominee or an H&F Nominee shall cease to serve as a Director for any reason (including any removal thereof), the Carlyle Entities or
the H&F Entities, respectively, shall have the right to appoint another Carlyle Nominee or an H&F Nominee, respectively, to fill any vacancy resulting therefrom. For the avoidance of doubt, it is understood that the failure of the
stockholders of the Company to elect any Carlyle Nominee or any H&F Nominee, shall not affect the right of the Carlyle Entities or the H&F Entities, as applicable, to designate the Carlyle Nominees or the H&F Nominees, as the case may
be, for election pursuant to this Section 2.1(c) in connection with any future election of Directors. 

(iv) Each Financial Investor that holds, or otherwise has voting control over, Voting Securities agrees with the Company (and
only with the Company) that it shall vote or cause to be voted all of such Voting Securities in favor of each individual standing for election as a director of the Company as part of the Company’s slate of directors that is included in the
proxy statement (or consent solicitation or similar document) of the Company relating to the election of directors in accordance with this Section 2.1(c) and whose election the Company Board has recommended. 

(d) Subsidiary Boards. The Company agrees with each of the Sponsors that for so long as both the Carlyle Entities and the H&F
Entities have the right to nominate at least one Director pursuant to this Section 2.1, if any H&F Nominee or Carlyle Nominee serves on the board of directors (or equivalent governing body) of any Subsidiary of the
Company, then unless otherwise agreed by the Sponsors, the Company shall cause such board of directors (or equivalent governing body) to be comprised of the same members as the Company Board. 

(e) Other Board of Directors Matters. 

(i) The Company shall reimburse the directors for all reasonable out-of-pocket expenses incurred in connection with their attendance at meetings of the Company Board and any committees thereof, including travel, lodging and meal expenses. 

(ii) The Company shall obtain, for each director nominated by a Sponsor Investor Group, customary director and officer
indemnity insurance on commercially reasonable terms as determined by the Company Board and that is reasonably acceptable to each Sponsor Investor Group that is then entitled to designate or nominate at least one director. 

  
 20 

 (iii) In addition to any other indemnification rights that the directors
have pursuant to the certificate of incorporation and the bylaws (or equivalent governing documents) of the Company, each person nominated by a Sponsor Investor Group to serve on the Company Board in accordance with this
Section 2.1 shall have the right to enter into, and the Company agrees to enter into, an indemnification agreement in a form consistent with indemnification agreements customarily entered into between companies and their
independent board members.

(y) such Limited Investor does not have a Director nominated by such Limited Investor serving on the on the Company Board, without limitation of or prejudice to any of the rights provided to such Limited Investor hereunder, the Company shall,

provided to the members of the Company Board; provided that the Company shall be entitled to redact portions of such materials to the extent that (i) such redaction is reasonably necessary to preserve attorney-client (or other similar)
privilege with respect to a matter or to protect highly confidential proprietary information or (ii) there exists, with respect to any such materials, an actual or potential conflict of interest between such Limited Investor and the Company;
provided further, that the Company shall not provide any such information to any Limited Investor for such long as such Limited Investor elects not to exercise its right to appoint a non-voting board
observer pursuant to Section 2.1(f)(i)(A). 
 (ii) For so long as a Limited Investor has the right
to designate one (1) non-voting board observer to the Company Board pursuant to Section 2.1(f)(i) (the “Limited Investor Board Observer”), if any H&F Nominee
or any Carlyle Nominee serves on the board of directors (or equivalent governing body) of any Subsidiary of the Company, then, the Company shall offer to such Limited Investor to include the Limited Investor Board Observer as a non-voting board observer to such board of directors (or equivalent governing body) and at the request of such Limited Investor, the Company shall cause such board of directors (or equivalent governing body) to
include such Limited Investor Board 

  
 21 

 Obersever as a non-voting board observer who will be
entitled to attend all meetings of such board of directors (or equivalent governing body) and participate in all deliberations of such board of directors (or equivalent governing body); provided that such observer shall have no voting rights
with respect to actions taken or elected not to be taken by such board of directors (or equivalent governing body); provided, further, that such board of directors (or equivalent governing body) shall be entitled to exclude such
observer from such portions of any of its meetings to the extent (x) such observer’s presence would be reasonably likely to result in the waiver of attorney-client (or other similar) privilege, (y) there exists, with respect to any
such materials, an actual or potential conflict of interest between such Limited Investor and the Company or (z) the removal of such observer is required under applicable law or the rules of any stock exchange applicable to the Company. The

directors (or equivalent governing body); provided that the Company or such Subsidiary shall be entitled to redact portions of such materials to the extent that (i) such redaction is reasonably necessary to preserve attorney-client (or
other similar) privilege with respect to a matter or to protect highly confidential proprietary information or (ii) there exists, with respect to any such materials, an actual or potential conflict of interest between such Limited Investor and
the Company or Subsidiary.

Company Board; provided that, (a) until such time as the Carlyle Entities are no longer entitled to nominate any directors pursuant to Section 2.1, to the extent permitted by Law and the rules of any stock
exchange on which the Shares may be listed, the Carlyle Entities shall be entitled to appoint at least one member to each committee of the Company Board, (b) until such time as the H&F Entities are no longer entitled to nominate any

necessary to preserve attorney-client privilege with respect to a matter or to protect highly confidential proprietary information or (ii) there exists, with respect to any such materials, an actual or potential conflict of interest between the
Blue Spectrum Investor or the GIC Investor, as applicable, and the Company; and, provided, further, that, for the avoidance of doubt, the Blue Spectrum Investor and/or the GIC Investor may at any time elect in writing not to receive such
materials and on receipt of such election, the Company shall cease to provide copies of any materials to the Blue Spectrum Investor and/or the GIC Investor, as applicable, and (y) any directors pursuant to Section 2.1,

 TRANSFER RESTRICTIONS 

Section 4.1 General Limitations on Transfers.

Agreement or subsequently acquired) by such Stockholder, unless such Transfer is made in accordance with the requirements of this Article IV, as may be applicable. 

(b) Transfer Books. The Company shall not record upon its books any attempted Transfer of Shares or Options held or Beneficially Owned

(c) Securities Laws Matters. Notwithstanding any other provision of this Agreement, no Stockholder shall Transfer any Shares or Options
unless (i) the Transfer is effected pursuant to an effective registration statement under the Securities Act and in compliance with any other applicable federal securities laws and state securities or “blue sky” laws or (ii) the
transferor shall have furnished the Company with such evidence as shall be reasonably acceptable to the Company to the effect that no such registration is required because of the availability of an exemption from registration under the Securities
Act and under any applicable state securities or “blue sky” laws and that the Transfer otherwise complies with any other applicable federal securities laws and state securities or “blue sky” laws and such representations and
covenants of the transferor as are reasonably requested by the Company to ensure compliance with any applicable federal securities laws and state securities or “blue sky” laws. 

  
 25

Transferee that involves a direct or indirect Transfer of an interest in the Stockholder but not a direct Transfer of Shares by such Stockholder, (y) sales of Shares pursuant to a registration statement under the Securities Act or
(z) subject to Section 4.1(f), under Rule 144 or in an In-Kind Distribution, no Transfer of Shares or Options (other than to the Company or its Subsidiaries or any
Stockholder) that would be otherwise permitted pursuant to this Agreement shall be effective unless (i) the transferee shall have executed an appropriate document (a “Joinder Agreement”) substantially in the form
attached hereto as Annex A or otherwise in form and substance reasonably satisfactory to the Company confirming that (A) the transferee takes such Shares or Options, as applicable, subject to all the terms and conditions of this
Agreement to the same extent as its transferor was bound by and entitled to the benefits of such provisions and (B) the Shares shall bear legends, substantially in the forms required by Section 4.8, and (ii) such

Shares acquired upon exercise of Options). 
 (e) [Reserved]. 

(f) Restrictions on Transfers by the Sponsor Investors. The Sponsor Investors shall not Transfer any Shares or Options to any other
Person (other than (x) any Transfer to Permitted Transferees effected in compliance with Section 4.2 or (y) any Charitable IKD made in connection with a Transfer pursuant to Article V), without the prior
written consent of all Sponsors, if such Transfer occurs prior to first anniversary of an IPO. Notwithstanding anything to the contrary set forth in this Agreement, in no event shall any Sponsor Investor be permitted to Transfer any Shares pursuant
to Rule 144 or to effect any distribution or similar Transfer of Shares to its partners, members, stockholders or other equityholders or beneficiaries (an “In-Kind Distribution”)

acceptable to the Company, the preservation of the Company’s privileged and confidential information. 
 (g) Restrictions on
Transfers by Stockholders Other than Sponsor Investors Prior to the first anniversary of an IPO. Prior to the first anniversary of an IPO, the Managers, the Blue Spectrum Entities and the GIC Entities shall not Transfer any Shares or Options to
any other Person without the prior written consent of the Company Board, other than Transfers of Shares (i) to Permitted Transferees pursuant to and in compliance with Section 4.2, (ii) to any other

  
 26 

 
Person pursuant to and in compliance with Section 4.4, (iii) in a Public Offering pursuant to and in compliance with Article V, (iv) pursuant to and in

indirect owners’ (as applicable) qualification for benefits under Section 892 of the Code or (y) solely as a result of the continued ownership of the Shares, require any of the Blue Spectrum Entities, or any of their direct or

Section 4.2 Permitted Transfers. Subject only to the restrictions in Section 4.1 and this
Section 4.2, any Stockholder may Transfer Shares to any Permitted Transferee, in whole at any time or in part from time to time; provided, however, that, if at any time after such a Transfer of Shares by a
Stockholder to a Person that is, at such time, a Permitted Transferee, such Person ceases to be a Permitted Transferee of such Stockholder (except as a result of (i) a bona fide restructuring of (x) The Carlyle Group or any one or more
business segments or business lines thereof, if such Stockholder or Person is a Carlyle Entity or (y) Hellman & Friedman LLC or any one or more business segments or business lines thereof, if such Stockholder or Person is an H&F
Entity, in each case, including any restructuring in connection with an initial public offering or (ii) following any such restructuring contemplated by clause (i), any change of control of any public company that controls such Stockholder or
such Person that, as a result of such prior restructuring, is not a change of control of such Person or such Stockholder, respectively), such Person shall transfer such Shares to such Stockholder or a Permitted Transferee of such Stockholder (or,
subject to the written consent of all Sponsors, the Company or any other Sponsor Investor) for cash consideration equal to the Fair Market Value of such Shares (or such other consideration (if any) to which such Person and such Stockholder agree);
provided, further, that at no time shall the aggregate number of holders of Shares by (1) the Blue Spectrum Entities or the GIC Entities as applicable, exceed twenty (20) at any one time or (2) any Manager Group exceed
three (3) at any one time or, in each case, such larger number to which the Company shall consent in writing (such consent not to be unreasonably withheld, conditioned or delayed). Notwithstanding the foregoing, without the prior written
consent of all Financial Investors, (x) no Carlyle Entity may Transfer any Shares pursuant to this Section 4.2 to any Permitted Transferee (other than a Permitted Sponsor Transferee) of such Carlyle Entity and (y) no H&F Entity
may Transfer any Shares pursuant to this Section 4.2 to any Permitted Transferee other than a Permitted Sponsor Transferee. 

Section 4.3 [Reserved]. 

Section 4.4 Tag-Along Rights. 

(a) Sale Notice. If, at any time (except with the prior written consent of all Financial Investors) prior to the first anniversary of an IPO,
any Sponsor Investor Group (the “Stockholder Sellers”) proposes to Transfer any of the Shares held by such Stockholder Sellers (other than any Transfer of Shares (i) to any Permitted Transferee pursuant to and in
compliance with Section 4.2, (ii) to the Company or (iii) pursuant to and in compliance with Article V or any 

  
 27 

 
Charitable IKD made in connection with a Transfer pursuant to Article V, then the Stockholder Sellers shall first give written notice (the “Sale Notice”) to each of
the Stockholders who are not part of that Sponsor Investor Group (each such other Stockholder, an “Eligible Tag-Along Stockholder”), stating that the Stockholder Sellers desire to make
such Transfer, referring to this Section 4.4, specifying the number of Shares proposed to be Transferred by the Stockholder Sellers (the “Offer Shares”), and specifying the price, the form of
consideration, name and description of the proposed Transferee (including, to the extent known by the Stockholder Sellers, the controlling Persons of such Transferee) (the “Proposed Transferee”), the other material terms
pursuant to which such Transfer is proposed to be made and, if the form of consideration is not solely cash payable in immediately available funds or cash equivalents, to the extent reasonably requested by any Eligible
Tag-Along Stockholder that is a Financial Investor, sufficient financial and other information in order for such Eligible Tag-Along Stockholders to reasonably evaluate
the consideration proposed to be delivered. Upon the written request by any Eligible Tag-Along Stockholder that is a Financial Investor within five (5) Business Days of delivery of the Sale Notice, the
Stockholder Sellers shall use commercially reasonable efforts to provide such other information related to the Proposed Transferee and/or proposed Transfer, as is reasonably requested by such Eligible
Tag-Along Stockholder. 
 (b) Tag-Along Election.
Within ten (10) Business Days of the date of receipt of the Sale Notice, each Eligible Tag-Along Stockholder that desires to participate in such Transfer (any Eligible
Tag-Along Stockholder that exercises such right, a “Tag-Along Stockholder” and, together with the Stockholder Sellers and all other Persons that
are exercising contractual or other rights to Transfer Shares in such transaction, the “Tag-Along Sellers”) shall deliver to the Stockholder Sellers and to the Company a written notice
stating how many Shares such Eligible Tag-Along Stockholder elects to Transfer (subject to the following sentences of this Section 4.4(b), such
Tag-Along Stockholder’s “Tag-Along Shares”). Subject to this Section 4.4, such
Tag-Along Stockholder may Transfer up to a number of Shares equal to its, his or her Tag-Along Pro Rata Portion to such Proposed Transferee on the Same Terms and
Conditions as the Stockholder Sellers and subject to the same indemnification (on a several and not joint basis) as the Stockholder Sellers. An election pursuant to the first sentence of this Section 4.4 shall constitute an
irrevocable commitment, subject to the terms of this Section 4.4, including Section 4.4(c), by the Tag-Along Stockholder making such election to sell such Tag-Along Shares to the Proposed Transferee if the sale of Offer Shares to the Proposed Transferee occurs on the terms set forth in the Sale Notice. Such terms shall include a maximum number of Shares such Proposed
Transferee is willing to purchase, and, in the event that the Proposed Transferee is not willing to acquire all the Shares offered, each Tag-Along Seller shall be cut back pro rata based on the number of
Shares such Tag-Along Seller offered to sell in accordance with the terms of Section 4.4(a) or this Section 4.4(b), as applicable, or, in the case of each Tag-Along Seller other than the Stockholder Sellers and the Tag-Along Stockholders, in accordance with such Tag Along Seller’s contract or other right to Transfer. With
respect to any Shares for which a Tag-Along Stockholder holds exercisable and vested but unexercised Options, to the extent that such Shares are to be sold pursuant to this
Section 4.4, such Tag-Along Stockholder must exercise the relevant Option (which exercise may be conditioned upon the closing of the Transfer pursuant to this
Section 4.4 and which may include an exercise effected on a “net exercise” basis to the extent permitted by the terms of such Option) and transfer the relevant Shares (rather than the Option), in each case, net of
any amounts required to be withheld by the Company in connection with such exercise. Notwithstanding anything to the contrary set forth in this Agreement, in no event may any Stockholder Transfer any Restricted Shares pursuant to this
Section 4.4. 

  
 28 

 (c) Rights to Transfer. 

(i) Third-Party Sale; Tag-Along Buyer. The Stockholder Sellers may not
consummate any Transfer that is subject to the provisions of this Section 4.4 unless the Proposed Transferee purchases, within 120 days of the date of the Sale Notice (subject to extension to the extent (x) necessary
to obtain required governmental approvals or clearances or (y) approved in writing by all Sponsors) (the “Tag-Along Sale Period”), simultaneously with the purchase of Shares from
the Stockholder Sellers, all of the Tag-Along Shares (subject to the cutback in Section 4.4(b)) on the Same Terms and Conditions, which terms and conditions include the same price as
set forth in the Sale Notice and otherwise are not materially less favorable than those set forth in the Sale Notice (the “Tag-Along Right”); provided, however, if, prior
to consummation, the terms of such proposed Transfer shall change with the result that the per share price shall be different (by more than a de minimis amount) than the per share price set forth in the Sale Notice or the other terms and conditions
shall be materially more or less favorable to any Tag-Along Stockholder than those set forth in the Sale Notice (including, for the avoidance of doubt, a material portion of the cash consideration being
changed to non-cash consideration, or vice versa), the acceptance by each Tag-Along Stockholder shall be deemed to be revoked, and it shall be necessary for a separate
Sale Notice to be furnished, and the terms and provisions of this Section 4.4 separately complied with, in order to consummate such Transfer pursuant to this Section 4.4. For purposes of the
preceding sentence, the price received by the Stockholder Sellers shall be deemed to include all compensation of any nature and type as is received by the Stockholder Sellers in respect of the Offer Shares. If at the end of the Tag-Along Sale Period, the Transfer has not been completed, the Sale Notice shall be null and void and each Tag-Along Stockholder shall be released from such Tag-Along Stockholder’s obligation in connection with the Sale Notice and it shall be necessary for a separate Sale Notice to be furnished and the terms and provisions of this
Section 4.4 separately complied with, in order to consummate such proposed Transfer pursuant to this Section 4.4. 

(ii) Sale Agreement. Each Tag-Along Stockholder agrees to cooperate in
consummating such Transfer, including by (A) becoming a party to the sale agreement and all other appropriate related agreements on the Same Terms and Conditions as the Stockholder Sellers, (B) delivering, at or before the consummation of
such Transfer, the stock certificates for such Shares, duly endorsed, or with stock (or equivalent) powers duly endorsed, for transfer with signature guaranteed, free and clear of any Encumbrances, with any stock (or equivalent) transfer tax stamps
affixed, against delivery of the applicable consideration, and (C) voting or consenting in favor of such transaction (to the extent a vote or consent is required), in each case, on the Same Terms and Conditions as the Stockholder Sellers, and
taking any other commercially reasonable necessary or appropriate action in furtherance thereof, including the execution and delivery of any other appropriate agreements, certificates, instruments and other documents. 

  
 29 

 (iii) Costs and Expenses. Each of the
Tag-Along Sellers shall be severally responsible for its proportionate share (apportioned pro rata based on the number of Shares the Tag-Along Sellers are Transferring
in such transaction) of the third-party expenses of the Transfer incurred by the Sponsor Investors in connection with such Transfer (except to the extent paid or reimbursed by the Company or the Proposed Transferee) and liabilities for
indemnification with respect to breaches of representations and warranties made in connection with such Transfer by the Company or any of its Subsidiaries or by the Tag-Along Sellers with respect to the
Company, any of its Subsidiaries or any of the Company’s or its Subsidiaries’ businesses, and shall also include amounts paid into escrow or subject to holdbacks, and amounts subject to post-closing purchase price adjustments;
provided, however, that all such obligations are on a several and not joint basis to the Tag-Along Sellers based on the number of Shares Transferred by the
Tag-Along Sellers in such Transfer. The foregoing notwithstanding, (A) the amount of such obligations and liabilities for which each Tag-Along Seller shall be
responsible shall not exceed the consideration actually received by such Tag-Along Seller in such Transfer, (B) a Tag-Along Seller shall not be required to make any
representations or warranties in connection with such Transfer except with respect to such Tag-Along Seller, the ownership of and title to its Shares and Options, its organization, its authority and its
absence of conflicts and consents, (C) a Tag-Along Seller shall not be responsible for any indemnification obligations and liabilities (other than through escrow or holdback arrangements if the breaching
Tag Along Seller indemnifies the other Tag Along Sellers for such liabilities) for breaches of representations and warranties and related escrow or holdback claims made by any other Tag-Along Seller with
respect to such other Tag-Along Seller’s (1) ownership of and title to its, his or her Shares, (2) organization, (3) authority or (4) absence of conflicts and consents and any other matter
concerning such other Tag-Along Seller, or for breaches of any covenant specifically relating to a Stockholder made by any other Tag-Along Seller, and (D) no Tag-Along Seller that is a Financial Investor shall be required in connection with such Transfer to (x) be subject to any restrictive covenant that the Sponsor Investors are not also subject to or
(y) enter into any (1) covenant or agreement not to solicit or hire employees (unless such covenant or agreement (A) excludes portfolio companies of such Financial Investor, except where such Financial Investor directs, encourages or
facilitates such solicitation or hiring and (B) excludes general solicitations (e.g., newspaper advertisements and hiring fairs) not targeted at specific employees) or (2) covenant not to compete. All costs and expenses incurred by the
Company or its Subsidiaries in connection with the proposed Transfer pursuant to this Section 4.4 (whether or not consummated), including all attorneys’ fees and expenses, all accounting fees and charges and all
finders, brokerage or investment banking fees, charges or commissions, will be paid by the Company or its Subsidiaries. Except as otherwise set forth in this Section 4.4(c)(iii), any costs and expenses incurred by or on
behalf of any or all Tag-Along Sellers in connection with any proposed Transfer pursuant to this Section 4.4 (whether or not consummated) will be borne by the applicable Tag-Along Seller. 
 (iv) Securities Law Considerations. Notwithstanding anything to
the contrary in this Section 4.4, in the event the consideration to be paid for Shares that are to be sold pursuant to this Section 4.4 includes any securities, and the receipt thereof by a Tag-Along Stockholder would require under applicable law (a) the registration or qualification of such securities or of any Person as a broker or dealer or agent with respect to such securities

  
 30 

 
where such registration or qualification is not otherwise required for the Transfer pursuant to this Section 4.4 by the Stockholder Sellers, or (b) the provision to
any Tag-Along Stockholder of any specified information regarding the Company or any of its Subsidiaries, such securities or the issuer thereof that is not otherwise required to be provided for such Transfer
pursuant to this Section 4.4 by the Stockholder Sellers, then (x) if such Tag-Along Stockholder is not a Financial Investor, such
Tag-Along Stockholder shall not have the option to sell Shares in such proposed Transfer pursuant to this Section 4.4, and (y) if such
Tag-Along Stockholder is a Financial Investor and the Proposed Transferee is not willing to effect such registration or provide such information, such Tag-Along
Stockholder shall have the option to sell Shares in such proposed Transfer and receive in lieu of such securities cash in an amount equal to the Fair Market Value of such Shares as of the date such securities otherwise would have been issued. In
such event, the Stockholder Sellers shall have the right, but not the obligation, to cause to be paid to such Tag-Along Stockholder in lieu of such securities, against surrender of the Shares which would have
otherwise been sold by such Tag-Along Stockholder to the Proposed Transferee in the proposed Transfer, an amount in cash equal to the Fair Market Value of such Shares as of the date such securities otherwise
would have been issued in exchange for such Shares. 
 (v) No Liability. Notwithstanding any other provision contained
in this Section 4.4, there shall be no liability on the part of the Company or the Stockholder Sellers in the event that any Transfer of Offer Shares pursuant to this Section 4.4 is not
consummated, except to the extent that the Company has failed to comply with Section 4.4. The decision whether to effect a Transfer subject to this Section 4.4 shall be in the sole and absolute
discretion of the Stockholder Sellers. 
 Section 4.5 [Reserved]. 

Section 4.6 [Reserved]. 

Section 4.7 [Reserved].

APPLICABLE STATE SECURITIES LAWS. 
 (ii) THE SECURITIES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO THE TERMS AND
CONDITIONS SET FORTH IN A[N] [SECOND AMENDED AND RESTATED] [AMENDED AND RESTATED] STOCKHOLDERS AGREEMENT, DATED AS OF [ , 2020][NOVEMBER 11, 2019][MAY 11, 2017], AS 

  
 31 

 
AMENDED, RESTATED OR SUPPLEMENTED FROM TIME TO TIME, COPIES OF WHICH MAY BE OBTAINED FROM THE ISSUER WITHOUT CHARGE UPON REQUEST. NO TRANSFER OF SUCH SECURITIES WILL BE MADE ON THE BOOKS OF THE

Agreement shall be filed with the corporate secretary of the Company, and kept with the records of the Company, and shall be made available for inspection by any holder of Shares at the principal executive offices of the Company. 

(c) Termination of Legend Restrictions. The legend required pursuant to Section 4.8(a)(i) shall be removed
from any certificates representing Shares following the written request of the holder thereof to the Company if (a) in the opinion of counsel with respect to federal U.S. securities laws (reasonably acceptable to the Company) or such other
evidence as shall be reasonably acceptable to the Company, the restriction described in such legend is no longer required in order to assure compliance with the Securities Act and the state securities or “blue sky” laws, or (b) such
Shares have been sold pursuant to an effective registration statement under the Securities Act or transferred pursuant to Rule 144 in accordance with the terms of this Agreement. The legend required pursuant to
Section 4.8(a)(ii) shall be removed from any certificates representing any particular Shares following the written request of the holder thereof to the Company if, in the reasonable judgment of the Company, the provisions
of this Agreement are no longer applicable to such Shares or this Agreement shall have terminated in accordance with its terms. Whenever a holder shall be entitled to removal of one or both legends required pursuant to
Section 4.8(a), the holder thereof shall be entitled to receive from the Company, without expense (other than applicable transfer taxes, if any, if such unlegended Shares are being delivered and transferred to any Person
other than the registered holder thereof), new certificates for a like number of Shares not bearing the relevant legend(s) set forth in Section 4.8(a).

Sponsor is participating, if neither clause (f) nor clause (g) includes the reasonable fees and disbursements of one counsel retained by such Sponsor, then the reasonable fees and disbursements of one counsel retained by such Sponsor,

 (o) “Shelf Registration Statement” means a Registration Statement of the Company filed with the SEC on Form S-3 or on Form S-1 for an offering to be made on a delayed or continuous basis pursuant to Rule 415 under the Securities Act (or any similar rule that may be adopted by the

Take-Down” means any offering or sale of Registrable Securities by a Shelf Holder pursuant to a Shelf Registration Statement.

Section 5.2 Shelf Registration. 

(a) Filing. Subject to the Company’s rights under Section 5.2(c) and the limitations set forth in
Section 5.2(d), the Company shall (i) use its reasonable best efforts to file and cause to be effective on the first Business Day of the thirteenth calendar month following an IPO, a Shelf Registration Statement with
the SEC (which, unless all Sponsor Holders request otherwise, shall be designated by the Company as an Automatic Shelf Registration Statement if the Company is a Well-Known Seasoned Issuer at the time of filing such Shelf Registration Statement with
the SEC), (ii) promptly (but in any event no later than fifteen (15) days prior to the filing of such Shelf Registration Statement) give written notice of the anticipated date of the filing of such Shelf Registration Statement to all Financial
Investor Holders and (iii) promptly (but in any event no later than eight (8) days prior to the filing of such Shelf Registration Statement) give written notice of the anticipated date of the filing of such Shelf Registration Statement
(including 

  
 35 

 
the Shelf Percentage applicable to such Shelf Registration Statement) to all Holders other than the Financial Investor Holders. The Company further agrees to use its good faith efforts to provide
advance notice as soon as reasonably practicable to the Financial Investor Holder(s) of its intention to file a Shelf Registration Statement; provided, however, the Company shall not be obligated hereby to provide any such advance
notice and, if provided, such advance notice shall not be binding in any respect. Such Shelf Registration Statement will permit or facilitate the sale and distribution of (x) all or such portion of the Registrable Securities the Financial
Investor Holder(s) joining in such registration as are specified in a written demand received by the Company within ten (10) Business Days after such written notice is given to such Financial Investor Holder(s) pursuant to clause
(ii) above, (y) all or such portion of the Registrable Securities of any Holder or Holders (other than the Financial Investor Holders) joining in such registration as are specified in a written demand received by the Company within five
(5) Business Days after such written notice is given to such other Holders pursuant to clause (iii) above (such amount not in any event to exceed for any such Holder (other than the Sponsor Holders) the Shelf Percentage applicable to such
Registration Statement multiplied by the number of Registrable Securities held by such Holder as of the date of such initial filing) (each such Holder and Financial Investor Holder, a “Shelf Holder”) and (z) all or such
portion of the Shares of any Third Party Holder that joins in such registration (each such Third Party Holder, a “Third Party Shelf Holder”); provided, however, that if the Company is permitted by applicable
law, rule or regulation to add selling stockholders and/or additional Registrable Securities to a Shelf Registration Statement without filing a post-effective amendment, or if the applicable Shelf Registration Statement is an Automatic Shelf
Registration Statement and the Company is a Well-Known Seasoned Issuer, a Holder may request the inclusion of such Holder’s Registrable Securities (such amount, in the case of any Holder other than a Sponsor Holder, together with all other
Registrable Securities of such Holder registered at any time on such Shelf Registration Statement not in any event to exceed the Shelf Percentage of the total Registrable Securities held by such Shelf Holder as of the date of the applicable initial
filing) in such Shelf Registration Statement at any time or from time to time, and the Company shall add such Registrable Securities to the Shelf Registration Statement as promptly as reasonably practicable, and such Holder shall be deemed a Shelf
Holder. If, on the date of any such demand, the Company does not qualify to file a Shelf Registration Statement, then the provisions of Section 5.3 hereof shall apply instead of this Section 5.2.

 (b) Continued Effectiveness. Except as otherwise agreed by all Sponsors, the Company shall use its reasonable best efforts to keep
each Shelf Registration Statement filed pursuant to Section 5.2(a) hereof continuously effective under the Securities Act (including by filing and having declared effective an additional Shelf Registration Statement if the
then effective Shelf Registration Statement is not permitted to be used pursuant to Rule 415(a)(5) under the Securities Act) in order to permit the Prospectus forming a part thereof to be usable by the Shelf Holders until the earlier of (i) the
date as of which all Registrable Securities registered by such Shelf Registration Statement have been sold pursuant to such Shelf Registration Statement or have otherwise ceased to be Registrable Securities and (ii) such shorter period as all
of the Sponsor Holders may agree with the Company in writing (such period of effectiveness, the “Shelf Period”). 
 (c)
Suspension of Filing or Registration. If the Company shall furnish to the Sponsor Holders that have requested inclusion of Registrable Securities in such Shelf Registration Statement, a certificate signed by the Chief Executive Officer or
equivalent senior executive of the Company, stating that the filing, effectiveness or continued use of a Shelf Registration Statement 

  
 36 

 
would require the Company to make an Adverse Disclosure, then the Company shall have a period of not more than sixty (60) days after the receipt of such certificate or such longer period as
such Sponsor Holders shall consent to in writing, within which to delay the filing or effectiveness (but not the preparation for filing and effectiveness) of such Shelf Registration Statement or, in the case of a Shelf Registration Statement that
has been declared effective, to suspend the use by Shelf Holders of such Shelf Registration Statement (in each case, a “Shelf Suspension”); provided, however, that, unless consented to in writing by all
Sponsors, the Company shall not be permitted to exercise more than two (2) Shelf Suspensions pursuant to this Section 5.2(c) and Demand Delays pursuant to Section 5.3(a)(ii) in the aggregate,
or aggregate Shelf Suspensions pursuant to this Section 5.2(c) and Demand Delays pursuant to Section 5.3(a)(ii) of more than an aggregate of ninety (90) days, in each case, during any
twelve-month (12) period. The Company shall deliver a copy of such certificate to each of the Shelf Holders and each Shelf Holder shall keep confidential the fact that a Shelf Suspension is in effect and such certificate and its contents for
the permitted duration of the Shelf Suspension or until otherwise notified by the Company; provided, however, that each Shelf Holder may disclose such information to Persons and in circumstances to whom and in which, as applicable,
Section 7.2 would permit disclosure of the terms of this Agreement. In the case of a Shelf Suspension that occurs after the effectiveness of the Shelf Registration Statement, the Shelf Holders agree to suspend use of the
applicable Prospectus for the permitted duration of such Shelf Suspension in connection with any sale or purchase of, or offer to sell or purchase, Registrable Securities, upon receipt of the certificate referred to above. The Company shall
immediately notify the Shelf Holders upon the termination of any Shelf Suspension, and (i) in the case of a Shelf Registration Statement that has not been declared effective, shall promptly thereafter file the Shelf Registration Statement and
use its reasonable best efforts to have such Shelf Registration Statement declared effective under the Securities Act and (ii) in the case of an effective Shelf Registration Statement, shall amend or supplement the Prospectus, if necessary, so
it does not contain any untrue statement of a material fact or omission to state a material fact required to be stated therein or necessary to make the statements therein not misleading prior to the expiration of the Shelf Suspension and furnish to
the Shelf Holders such numbers of copies of the Prospectus as so amended or supplemented as the Shelf Holders may reasonably request. The Company agrees, if necessary, to supplement or make amendments to the Shelf Registration Statement if required
by the registration form used by the Company for the Shelf Registration Statement or by the instructions applicable to such registration form or by the Securities Act or the rules or regulations promulgated thereunder or as may reasonably be
requested by the Shelf Holders of a majority of the Registrable Securities then outstanding. 
 (d) Shelf Take-Downs. 

(i) Right to Initiate and Participate in Shelf Take-Downs. A Shelf Take-Down may be initiated by any Shelf Holder;
provided that, subject to the terms and limitations of this Article V, only one or more Financial Investors may initiate a Marketed Underwritten Shelf Take-Down pursuant to Section 5.2(d)(iii) or request that
a Shelf Take-Down be effected by means of an underwritten offering pursuant to Section 5.2(d)(iv) and, provided, further, that none of the GIC Holders or Blue Spectrum Holders (as applicable) may initiate a
Shelf Take-Down if any of the GIC Holders or Blue Spectrum Holders, respectively, have participated in any sale of Registrable Securities pursuant to this Article V during the prior six months. Except with respect to Restricted Shelf
Take-Downs to the extent provided by Section 5.2(d)(ii) and Marketed Underwritten Shelf Take-Downs, no Shelf Holder initiating a Shelf Take-Down shall be required to permit the offer and sale of Registrable Securities by
any other Shelf Holder in connection with such Shelf Take-Down. 

  
 37 

 (ii) Restricted Shelf Take-Downs. 

(A) Subject to clause (E) below, with respect to each Shelf Take-Down (other than a Marketed Underwritten Shelf Take-Down)
that is initiated by a Financial Investor Holder (a “Restricted Shelf Take-Down”), such Financial Investor Holder shall provide written notice (a “Restricted Shelf Take-Down Notice”) of such Restricted
Shelf Take-Down to the Company and each Eligible Take-Down Holder with respect to such Restricted Shelf Take-Down as far in advance of such Restricted Shelf Take-Down as shall be reasonably practicable in light of the circumstances applicable to
such Restricted Shelf Take-Down, which Restricted Shelf Take-Down Notice shall set forth (I) the total number of Registrable Securities expected to be offered and sold in such Restricted Shelf Take-Down, (II) the expected plan of
distribution of such Restricted Shelf Take-Down, (III) the fraction, expressed as a percentage, determined by dividing the number of Registrable Securities anticipated to be sold by such Financial Investor Holder in such Restricted Shelf
Take-Down by the total number of Registrable Securities held by such Financial Investor Holder (the “Shelf Take-Down Percentage”), (IV) an invitation to each Eligible Take-Down Holder to elect (Eligible Take-Down Holders who
make such an election being “Take-Down Tagging Holders” and, together with such Financial Investor Holder, and all Third Party Shelf Holders that exercise a contractual or other right to Transfer Shares in connection with
such Restricted Shelf Take-Down, the “Restricted Take-Down Selling Holders”) to include in the Restricted Shelf Take-Down Registrable Securities held by such Take-Down Tagging Holder and registered on such Shelf Registration
Statement and (V) the action or actions required (including the timing thereof) in connection with such Restricted Shelf Take-Down with respect to each Eligible Take-Down Holder that elects to exercise such right (including the delivery of one
or more stock certificates representing Registrable Securities of such Eligible Take-Down Holder to be sold in such Restricted Shelf Take-Down). For the avoidance of doubt, it is understood that the Restricted Shelf Take-Down Notice need not include
the price per Registrable Security or the other terms and conditions with respect to payment for the Registrable Securities to be sold in such Restricted Shelf Take-Down. Each Financial Investor Holder further agrees to use its good faith efforts to
provide advance notice as soon as reasonably practicable to the other Financial Investor Holders that are Eligible Take-Down Holders of such first Financial Investor Holder’s intention to deliver a Restricted Take-Down Notice; provided,
however, that no Financial Investor Holder shall be obligated hereby to provide any such advance notice and, if provided, such advance notice shall not be binding in any respect. 

  
 38 

 (B) Subject to clause (E) below, upon delivery of a Restricted Shelf
Take-Down Notice, each Eligible Take-Down Holder may elect to sell Registrable Securities in such Restricted Shelf Take-Down, at the same price per Registrable Security and pursuant to the same terms and conditions with respect to payment for the
Registrable Securities as agreed to by such Financial Investor Holder, by sending an irrevocable written notice (a “Restricted Take-Down Participation Notice”) to such Financial Investor Holder within the time period
specified in such Restricted Shelf Take-Down Notice (which shall be no sooner than five (5) days after such Sponsor Holder’s delivery of the applicable Restricted Shelf Take-Down Notice), indicating its, his or her election to sell up to
the number of Registrable Securities in the Restricted Shelf Take-Down specified by such Eligible Take-Down Holder in such Restricted Take-Down Participation Notice (subject to the limitations in Section 5.2(d)(ii)(C) and,
if applicable, Section 5.2(d)(iv)). Following the time period specified in such Restricted Shelf Take-Down Notice, each Take-Down Tagging Holder that has delivered a Restricted Take-Down Participation Notice shall be
permitted to sell in such Restricted Shelf Take-Down on the terms and conditions set forth in the Restricted Shelf Take-Down Notice, concurrently with such Financial Investor Holder and the other Restricted Take-Down Selling Holders, the number of
Registrable Securities calculated pursuant to Section 5.2(d)(ii)(C). For the avoidance of doubt, in the event that a Restricted Shelf Take-Down contemplates the distribution of Registrable Securities by means of an
underwritten offering, it is understood that in order to be entitled to exercise its, his or her right to sell Registrable Securities in a Restricted Shelf Take-Down pursuant to this Section 5.2(d)(ii), each Take-Down
Tagging Holder must comply with Section 5.2(d)(iv). 
 (C) Subject to clause (F) below, each
of the Restricted Take-Down Selling Holders shall be entitled to sell in the Restricted Shelf Take-Down a number of Registrable Securities calculated as follows: 

(1) first there shall be allocated to each Restricted Take-Down Selling Holder a number of Registrable Securities equal to the
lesser of (A) the maximum number of Registrable Securities such Restricted Take-Down Selling Holder has elected to sell in the Restricted Shelf Take-Down in its, his or her Restricted Shelf Take-Down Notice or Restricted Take-Down Participation
Notice and (B) the number of Registrable Securities determined by multiplying (x) the number of Registrable Securities subject to the Restricted Shelf Take-Down by (y) a fraction the numerator of which is the number of Registrable
Securities held by such Restricted Take-Down Selling Holder and the denominator of which is the total Registrable Securities held by all Restricted Take-Down Selling Holders (the “Pro Rata Take-Down Share”); and 

(2) any remaining Registrable Securities subject to the Restricted Shelf Take-Down shall be allocated to the Restricted
Take-Down Selling Holders that elected to sell in excess of their Pro Rata Take-Down Share, pro rata to such Restricted Take-Down Selling Holders based upon such Restricted Take-Down Selling Holders’ relative Pro Rata Take-Down Shares (subject,
in the case of each Restricted Take-Down Selling Holder, to the maximum number of Registrable Securities contemplated in Section 5.2(d)(ii)(C)(1)(A)), or as such Restricted Take-Down Selling Holders may otherwise agree in
writing among themselves. 

  
 39 

 (D) Notwithstanding the delivery of any Restricted Shelf Take-Down Notice,
all determinations as to whether to complete any Restricted Shelf Take-Down and as to the timing, manner, price and other terms of any Restricted Shelf Take-Down shall be at the sole discretion of the initiating Financial Investor Holder. In
furtherance of this Section 5.2(d)(ii), each of the Financial Investors agrees to reasonably cooperate with each of the Eligible Take-Down Holders (as applicable from time to time) to establish notice, delivery and
documentation procedures and measures to facilitate such Eligible Take-Down Holder’s participation in future potential Restricted Shelf Take-Downs pursuant to this Section 5.2(d)(ii). 

(E) Anything in this Section 5.2(d) to the contrary notwithstanding, any Restricted Shelf Take-Down
must involve the offer and sale by the Financial Investor Holders initiating such Restricted Shelf Take-Down of Registrable Securities having a reasonably anticipated net aggregate offering price (after deduction of underwriter commissions and
offering expenses) of at least $75,000,000 unless such Restricted Shelf Take-Down is for all of the Registrable Securities then held by such Financial Investor Holders and their Permitted Transferees (in which case there is no minimum other than the
inclusion of all of such Registrable Securities). 
 (iii) Marketed Underwritten Shelf Take-Downs. Subject to clauses
(D) and (E) below, if the Company shall receive from a Financial Investor Holder a written notification (a “Marketed Take-Down Notice”) that a Shelf Take-Down by such Financial Investor Holder contemplates the
distribution of Registrable Securities by means of an underwritten offering that will involve a customary “road show” (including any “electronic road show”) or other substantial marketing efforts by the underwriter or
underwriters over a period of at least 48 hours (a “Marketed Underwritten Shelf Take-Down”), the Company will: 

(A) promptly (but in no less than ten (10) Business Days prior to the expected date of consummation of such Marketed
Underwritten Shelf Take-Down) give written notice of the proposed Marketed Underwritten Shelf Take-Down to all other Shelf Holders; and 

(B) use its reasonable best efforts to effect such Marketed Underwritten Shelf Take-Down as soon as practicable as will permit
or facilitate the sale and distribution of all or such portion of such Financial Investor Holders’ Registrable Securities as are specified in such Marketed Take-Down Notice, together with all or such portion of the Registrable Securities
registered on such Shelf Registration Statement of any other Shelf Holders joining in such Marketed Underwritten Shelf Take-Down as are specified in a written notice received by the Company within ten (10) Business Days after such written
notice is given by the Company pursuant to Section 5.2(d)(iii)(A), in each case except as set forth in Section 5.2(d)(iv) below. 

  
 40 

 (C) Each Financial Investor Holder further agrees to use its good faith
efforts to provide advance notice as soon as reasonably practicable to the other Financial Investor Holders that are Shelf Holders of such first Financial Investor Holder’s intention to deliver a Marketed Take-Down Notice; provided, however,
that no Financial Investor Holder shall be obligated hereby to provide any such advance notice and, if provided, such advance notice shall not be binding in any respect. 

(D) Anything in this Section 5.2(d) to the contrary notwithstanding, any Marketed Underwritten Shelf
Take-Down must involve the offer and sale by the Financial Investor Holders initiating such Restricted Shelf Take-Down of Registrable Securities having a reasonably anticipated net aggregate offering price (after deduction of underwriter commissions
and offering expenses) of at least $100,000,000. 
 (E) Anything in this Section 5.2(d) to the contrary notwithstanding,
(1) the GIC Holders (collectively) shall only be entitled to initiate a total of one Marketed Underwritten Shelf Take-Down or one Demand Registration in aggregate, (2) the Blue Spectrum Holders (collectively) shall only be entitled to
initiate a total of one Marketed Underwritten Shelf Take-Down or one Demand Registration in aggregate and (3) the GIC Holders and the Blue Spectrum Holders cannot deliver a Marketed Take-Down Notice or a written demand for Demand Registration
prior to the second anniversary of the IPO. 
 (iv) Underwriting. If a Financial Investor Holder delivering a
Restricted Shelf Take-Down Notice or a Marketed Take-Down Notice intends to distribute the Registrable Securities in such Shelf Take-Down by means of an underwritten offer, it shall so advise the Company and the Eligible Take-Down Holders in such
Restricted Shelf Take-Down Notice or the Company in such Marketed Take-Down Notice, as applicable (and, in the case of a Marketed Take-Down Notice, the Company shall include such information in the written notice referred to in
Section 5.2(d)(iii)(A)). In such event, the right of any Shelf Holder to participate in such Shelf Take-Down pursuant to this Section 5.2(d) shall be conditioned upon such Shelf Holder’s
participation in such underwriting and the inclusion of such Shelf Holder’s Registrable Securities in the underwriting to the extent provided herein. The Sponsors (and if the Financial Investor Holder initiating such offering is an Blue
Spectrum Holder or a GIC Holder, such Holder) will cooperate in good faith to mutually select the underwriter or underwriters for such offer; provided that, a Sponsor will not be entitled to participate in the selection of the underwriter or
underwriters unless the Restricted Take-Down Selling Holders include at least one member of such Sponsor’s Sponsor Investor Group. The Company shall, together with all holders of Registrable Securities of the Company proposing to distribute
Registrable Securities through such underwriting, enter into an underwriting agreement in customary form with such underwriter or underwriters, and each Shelf Holder participating in such underwriting shall perform its obligations under such
underwriting agreement. Notwithstanding any other provision of this Section 5.2(d), if the underwriter or underwriters shall advise the Company and the Financial Investor Holders participating in such Shelf Take-Down that
marketing factors (including an adverse effect on the per share offering price) require a 

  
 41 

 limitation of the number of Shares to be underwritten, then the Company shall so advise all
Shelf Holders participating in such Shelf Take-Down pursuant to this Section 5.2(d), and the number of shares of Registrable Securities that may be included in the underwriting shall be allocated in the following manner:
first, among the Shelf Holders participating in such Shelf Take-Down on a pro rata basis based on the total number of Registrable Securities held by such Holders, and second, among any Third Party Shelf Holders that are exercising a contractual or
other right to dispose of Shares in such underwriting thereof and the Company on a pro rata basis based on the total number of Shares held by such Third Party Shelf Holders or proposed to be offered by the Company. No Registrable Securities or other
Shares excluded from the underwriting by reason of the underwriter’s marketing limitation shall be included in such registration. 

Section 5.3 Demand Registration. 

(a) Financial Investor Holders’ Demand for Registration. If, (i) after the earlier of (x) the twelfth
calendar month following the IPO and (y) such other date as may be agreed in writing by all Sponsors, the Company shall receive from one or more of the Sponsor Holders or (ii) after the second anniversary of the IPO, the Company shall
receive from one or more of the Blue Spectrum Entities or the GIC Entities (as applicable, the Sponsor Holders, together with, subject to the limitations in this Section 5.3, the Blue Spectrum Entities and the GIC Entities,
each a “Demand Holder”) a written demand that the Company effect any registration (a “Demand Registration”) of Registrable Securities of such Holders having a reasonably anticipated net aggregate
offering price (after deduction of underwriter commissions and offering expenses) of at least $100,000,000, the Company will: 

(i) promptly (but in any event no less than ten (10) days prior to the date such registration becomes effective under the
Securities Act) give written notice of the proposed registration to all other Holders; and 
 (ii) use its reasonable best
efforts to effect such registration as soon as practicable as will permit or facilitate the sale and distribution of all or such portion of such Demand Holders’ Registrable Securities as are specified in such demand, together with all or such
portion of the Registrable Securities of any other Holders joining in such Demand Registration as are specified in a written demand received by the Company within five (5) days after such written notice is given by the Company pursuant to
Section 5.3(a)(i) (provided, that such period for responding shall be ten (10) Business Days if the distribution of Registrable Securities in connection therewith will be by means of an underwritten offering
that will involve a customary “road show” (including any “electronic road show”) or other substantial marketing efforts by the underwriter or underwriters over a period of at least 48 hours), except as set forth in
Section 5.3(b) below; provided that the Company shall not be obligated to file any Registration Statement or other disclosure document pursuant to this Section 5.3 (but shall be obligated to
continue to prepare such Registration Statement or other disclosure document) if the Company shall furnish to such Demand Holder and the Sponsors a certificate signed by the Chief Executive Officer or equivalent senior executive of the Company,
stating that the filing or effectiveness of such Registration Statement would require the Company to make an Adverse Disclosure, in which case the Company shall have an additional period (each, a “Demand Delay”) of not

  
 42 

 more than sixty (60) days (or such longer period as may be agreed upon by such Demand
Holder) within which to file such Registration Statement; provided, however, that the Company shall not exercise more than two (2) Demand Delays pursuant to this Section 5.3(a)(ii) and Shelf Suspensions
pursuant to Section 5.2(c) in the aggregate, or aggregate Demand Delays pursuant to this Section 5.3(a)(ii) and Shelf Suspensions pursuant to Section 5.2(c) of more than
an aggregate of ninety (90) days, in each case, during any twelve-month (12) month period. The Company shall deliver a copy of such certificate to each of the Holders and such Holders shall keep confidential the fact that a Demand Delay is
in effect and the certificate referred to above and its contents for the permitted duration of the Demand Delay or until otherwise notified by the Company; provided, however, that each Shelf Holder may disclose such information to
Persons and in circumstances to whom and in which, as applicable, Section 7.2 would permit disclosure of the terms of this Agreement. 

Each Financial Investor Holder further agrees to use its good faith efforts to provide advance notice as soon as reasonably practicable to the other Financial
Investor Holder(s) of such first Financial Investor Holder’s intention to deliver to the Company a Demand Registration notice; provided, however, that no Financial Investor Holder shall be obligated hereby to provide any such
advance notice and, if provided, such advance notice shall not be binding in any respect. 
 (b) Underwriting. If the Demand Holder
intends to distribute the Registrable Securities covered by its demand by means of an underwritten offer, it shall so advise the Company as part of its demand made pursuant to this Section 5.3, and the Company shall include
such information in the written notice referred to in Section 5.3(a)(i). In such event, the right of any Holder to participate in such registration pursuant to this Section 5.3 shall be conditioned
upon such Holder’s participation in such underwriting and the inclusion of such Holder’s Registrable Securities in the underwriting to the extent provided herein. The Sponsors (and, if the Demand Holder is a Financial Investor Holder other
than a Sponsor Investor, such Demand Holder) will cooperate in good faith to mutually select the underwriter or underwriters for such offer; provided that, a Sponsor will not be entitled to participate in the selection of the underwriter or
underwriters unless at least one member of such Sponsor’s Sponsor Investor Group proposes to include its Registrable Securities in such offering. The Company shall, together with all holders of Registrable Securities of the Company proposing to
distribute their securities through such underwriting, enter into an underwriting agreement in customary form with the underwriter or underwriters selected by the Demand Holder and reasonably satisfactory to the Company, and each Holder
participating in such underwriting shall perform its obligations under such underwriting agreement. Notwithstanding any other provision of this Section 5.3, if the underwriter shall advise the Company and the Sponsors (and,
if the Demand Holder is a Financial Investor other than a Sponsor Investor, such Demand Holder) participating in such underwritten offering that marketing factors (including an adverse effect on the per share offering price) require a limitation of
the number of shares to be underwritten, then the Company shall so advise all Holders of Registrable Securities that have requested to participate in such offering, and the number of shares of Registrable Securities that may be included in the
registration and underwriting shall be allocated in the following manner (except as all Sponsors (and, if the Demand Holder is a Financial Investor other than a Sponsor Investor, such Demand Holder) otherwise may agree in writing): first,
among the Holders participating in such underwritten offering on a pro rata basis based on the total number of Registrable Securities held by such Holders, and second, among any Third Party Holders that

  
 43 

 
are exercising a contractual or other right to dispose of Shares in such underwriting thereof and the Company on a pro rata basis based on the total number of Shares held by such Third Party
Holders or proposed to be offered by the Company. No Registrable Securities or other Shares excluded from the underwriting by reason of the underwriter’s marketing limitation shall be included in such registration or proposed to be offered by
the Company. 
 (c) Effective Registration. The Company shall be deemed to have effected a Demand Registration if the Registration
Statement pursuant to such registration is declared effective by the SEC and remains effective for (x) not less than one hundred eighty (180) days (or if such Registration Statement relates to an underwritten offering, such longer period
as, in the opinion of counsel for the underwriters, a prospectus is required by law to be delivered in connection with sales of Registrable Securities by an underwriter or dealer) or until the Holder or Holders have completed the distribution
relating thereto or (y) for such longer period as may be prescribed herein (the applicable period, the “Demand Period”). 

(d) Right to Terminate or Withdraw a Demand Registrations. A Demand Holder may withdraw its Registrable Securities from a Demand
Registration at any time prior to the effectiveness of the applicable Registration Statement. Upon delivery of a notice by the Sponsors (and, if the Demand Holder is a Financial Investor other than a Sponsor Investor, such Demand Holder)
participating in such Demand Registration to the following effect, the Company shall cease all efforts to secure effectiveness of the applicable Registration Statement. In addition, any other Holder that has requested its Registrable Securities be
included in a Demand Registration pursuant to Section 5.3(a)(ii) may withdraw its Registrable Securities from a Demand Registration at any time prior to the effectiveness of the applicable Registration Statement. 

(e) Limitation on Certain Demand Holders. Notwithstanding anything to the contrary in this Agreement, (x) under no circumstances
shall the Company be obligated to effect a Demand Registration by any Blue Spectrum Entity or GIC Entity prior to the two year anniversary of the IPO and (y) the right of the Blue Spectrum Holders and the GIC Holders to request a Demand
Registration is subject to clause (E) of Section 5.2(d)(iii). 
 Section 5.4 Piggyback
Registration. 
 (a) Registrations. If at any time or from time to time, the Company shall determine to register any of its Equity
Securities, either for its own account or for the account of security holders (other than (1) in a registration relating solely to employee benefit plans, (2) a Registration Statement on Form S-4 or S-8 (or such other similar successor forms then in effect under the Securities Act), (3) a registration pursuant to which the Company is offering to exchange its own securities for other securities, (4) a
Registration Statement relating solely to dividend reinvestment or similar plans, (5) a Shelf Registration Statement pursuant to which only the initial purchasers and subsequent transferees of debt securities or preferred stock of the Company
or any of its Subsidiary that are convertible or exchange for Shares and that are initially issued pursuant to Rule 144A (or any analogous successor provision) and/or Regulation S (or any analogous successor provision) promulgated under the
Securities Act may resell such notes or preferred stock and sell the Shares into which such notes may be converted or exchanged or (6) a registration pursuant to Section 5.2 or Section 5.3
hereof, the Company will: 
 (i) promptly (but in no event less than ten (10) days before the effective date of the
relevant Registration Statement) give to each Holder written notice thereof; and 

  
 44 

 (ii) include in such registration (and any related qualification under state
securities laws or other compliance), and in any underwriting involved therein, all the Registrable Securities specified in a written request or requests made within five (5) days after receipt of such written notice from the Company by any
Holder or Holders, except as set forth in Section 5.4(b) below (provided, that such period for providing a written request shall be ten (10) Business Days if the distribution of Registrable Securities in
connection therewith will be by means of an underwritten offering that will involve a customary “road show” (including any “electronic road show”) or other substantial marketing efforts by the underwriter or underwriters over a
period of at least 48 hours). 
 The Company further agrees to use its good faith efforts to provide advance notice as soon as reasonably practicable to the
Financial Investor Holders of its intention to deliver a notice pursuant to clause (i); provided, however, that the Company shall not be obligated hereby to provide any such advance notice and, if provided, such advance notice shall
not be binding in any respect. Notwithstanding the foregoing, this Section 5.4 shall not apply to any Holder with respect to any such registration unless one or more of the Sponsor Investors elect to participate in such
registration. 
 (b) Underwriting. If the registration of which the Company gives notice is for a registered public offering involving an
underwriting, the Company shall so advise the Holders as a part of the written notice given pursuant to Section 5.4(a)(i). In such event the right of any Holder to participate in such registration pursuant to this
Section 5.4 shall be conditioned upon such Holder’s participation in such underwriting and the inclusion of such Holder’s Registrable Securities in the underwriting to the extent provided herein. All Holders
proposing to distribute their Registrable Securities through such underwriting, together with the Company and the other parties distributing their securities through such underwriting, shall enter into an underwriting agreement in customary form
with the underwriter or underwriters selected for such underwriting by the Company, and each Holder participating in such underwriting shall perform its obligations under such underwriting agreement. Notwithstanding any other provision of this
Section 5.4, if the underwriters shall advise the Company that marketing factors (including, without limitation, an adverse effect on the per share offering price) require a limitation of the number of shares to be
underwritten, then the Company may limit the number of Registrable Securities to be included in the registration and underwriting, subject to the terms of this Section 5.4. The Company shall so advise all Holders of
Registrable Securities that have requested to participate in such offering, and the number of shares of Registrable Securities that may be included in the registration and underwriting shall be allocated in the following manner: first, to the
Company and second, to the Holders and any Third Party Holders exercising a contractual or other right to dispose of Registrable Securities in such underwriting on a pro rata basis based on the total number of Shares held by such Persons. No
such reduction shall reduce the securities being offered by the Company for its own account to be included in the registration and underwriting. No Registrable Securities or other Shares excluded from the underwriting by reason of the
underwriter’s marketing limitation shall be included in such registration. Notwithstanding anything to the contrary herein, the Sponsors acting together may mutually waive the rights of Holders under this Section 5.4
to include any Registrable Securities in a registration so long as none of the Sponsor Investors include Registrable Securities in such registration. 

  
 45 

 (c) Right to Terminate or Withdraw a Registration. The Company shall have the right
to terminate or withdraw any registration initiated by it under this Section 5.4 prior to the effectiveness of such registration whether or not any Holder has elected to include securities in such registration. 

Section 5.5 Expenses of Registration. All Registration Expenses incurred in connection with all registrations effected pursuant to
Section 5.2, Section 5.3 or Section 5.4, shall be borne by the Company. For the avoidance of doubt, it is understood that the Company shall not be required to pay stock
transfer taxes or underwriters’ discounts or selling commissions relating to Registrable Securities. 
 Section 5.6 Obligations
of the Company. Whenever required under this Article V to effect the registration or offering of any Registrable Securities, the Company shall, as expeditiously as reasonably possible: 

(a) prepare and file with the SEC a Registration Statement with respect to such Registrable Securities and use its reasonable best efforts to
cause such Registration Statement to become effective and keep such Registration Statement effective for (x) not less than one hundred eighty (180) days (or if such Registration Statement relates to an underwritten offering, such longer
period as, in the opinion of counsel for the underwriters, a prospectus is required by law to be delivered in connection with sales of Registrable Securities by an underwriter or dealer) or until the Holder or Holders have completed the distribution
relating thereto or (y) for such longer period as may be prescribed herein; 
 (b) prepare and file with the SEC such amendments and
supplements to such Registration Statement and the prospectus used in connection with such Registration Statement as may be necessary to keep such Registration Statement effective and to comply with the provisions of the Securities Act with respect
to the disposition of all Registrable Securities covered by such Registration Statement in accordance with the intended methods of disposition by sellers thereof set forth in such Registration Statement; 

(c) permit any Holder that (in the good faith reasonable judgment of such Holder) might be deemed to be a controlling person of the Company to
participate in good faith in the preparation of such Registration Statement and to cooperate in good faith to include therein material, furnished to the Company in writing, that in the reasonable judgment of such Holder and its counsel should be
included; 
 (d) furnish to the Holders such numbers of copies of the Registration Statement and the related Prospectus, including all
exhibits thereto and documents incorporated by reference therein and a preliminary prospectus, in conformity with the requirements of the Securities Act, and such other documents as they may reasonably request in order to facilitate the disposition
of Registrable Securities owned by them; 

  
 46 

 (e) in the event of any underwritten public offering of Registrable Securities, enter into
and perform its obligations under an underwriting agreement and any related agreements, in usual and customary form, with the managing underwriter(s) of such offering; 

(f) notify each Sponsor Holder (and, in connection with any Demand Registration for which the Demand Holder is a Financial Investor other than
a Sponsor Investor, such Demand Holder) of Registrable Securities covered by such Registration Statement as soon as reasonably possible after notice thereof is received by the Company of any written comments by the SEC or any request by the SEC or
any other federal or state governmental authority for amendments or supplements to such Registration Statement or such prospectus or for additional information; 

(g) notify each Holder of Registrable Securities covered by such Registration Statement, at any time when a prospectus relating thereto is
required to be delivered under the Securities Act, of the happening of any event as a result of which the prospectus included in such Registration Statement, as then in effect, includes an untrue statement of a material fact or omits to state a
material fact required to be stated therein or necessary to make the statements therein not misleading in the light of the circumstances then existing; 

(h) notify each Holder of Registrable Securities covered by such Registration Statement as soon as reasonably practicable after notice thereof
is received by the Company of the issuance by the SEC of any stop order suspending the effectiveness of such Registration Statement or any order by the SEC or any other regulatory authority preventing or suspending the use of any preliminary or
final prospectus or the initiation or threatening of any proceedings for such purposes, or any notification with respect to the suspension of the qualification of the Registrable Securities for offering or sale in any jurisdiction or the initiation
or threatening of any proceeding for such purpose; 
 (i) use its reasonable best efforts to prevent the issuance of any stop order
suspending the effectiveness of any Registration Statement or of any order preventing or suspending the use of any preliminary or final prospectus and, if any such order is issued, to obtain the withdrawal of any such order as soon as practicable;

 (j) make available for inspection by each Holder including Registrable Securities in such registration, any underwriter participating in
any distribution pursuant to such registration, and any attorney, accountant or other agent retained by such Holder or underwriter, all financial and other records, pertinent corporate documents and properties of the Company, as such parties may
reasonably request, and cause the Company’s officers, directors and employees to supply all information reasonably requested by any such Holder, underwriter, attorney, accountant or agent in connection with such Registration Statement; 

(k) use its reasonable best efforts to register or qualify, and cooperate with the Holders of Registrable Securities covered by such
Registration Statement, the underwriters, if any, and their respective counsel, in connection with the registration or qualification of such Registrable Securities for offer and sale under the securities or “Blue Sky” laws of each state
and other jurisdiction of the United States as any such Holder or underwriters, if any, or their respective counsel reasonably request in writing, and do any and all other things reasonably necessary or 

  
 47 

 
advisable to keep such registration or qualification in effect for such period as required by Section 5.2(b) and Section 5.3(c), as applicable;
provided that the Company shall not be required to qualify generally to do business in any jurisdiction where it is not then so qualified or take any action which would subject it to taxation or service of process in any such jurisdiction
where it is not then so subject; 
 (l) obtain for delivery to the Holders of Registrable Securities covered by such Registration Statement
and to the underwriters, if any, an opinion or opinions from counsel for the Company, dated the effective date of the Registration Statement or, in the event of an underwritten offering, the date of the closing under the underwriting agreement, in
customary form, scope and substance, which opinions shall be reasonably satisfactory to such holders or underwriters, as the case may be, and their respective counsel; 

(m) in the case of an underwritten offering, obtain for delivery to the Company and the underwriters, with copies to the Holders of Registrable
Securities included in such registration, a cold comfort letter from the Company’s independent certified public accountants in customary form and covering such matters of the type customarily covered by cold comfort letters as the managing
underwriter or underwriters reasonably request, dated the date of execution of the underwriting agreement and brought down to the closing under the underwriting agreement;

(2) Business Days prior to any sale of Registrable Securities; 
 (q) use its reasonable best efforts to comply with all applicable
securities laws and make available to its Holders, as soon as reasonably practicable, an earnings statement satisfying the provisions of Section 11(a) of the Securities Act and the rules and regulations promulgated thereunder; and 

(r) in the case of an underwritten offering, cause the senior executive officers of the Company to participate in the customary “road
show” presentations that may be reasonably requested by the underwriters and otherwise to facilitate, cooperate with and participate in each proposed offering contemplated herein and customary selling efforts related thereto.

 Section 5.7 Indemnification. 

(a) The Company will, and does hereby undertake to, indemnify and hold harmless each Holder of Registrable Securities and each of such
Holder’s officers, directors, trustees, employees, partners, managers, members, stockholders, beneficiaries, affiliates and agents and each Person, if any, who controls such Holder, within the meaning of either Section 15 of the Securities
Act or Section 20 of the Exchange Act, with respect to any registration, qualification, compliance or sale effected pursuant to this Article V, and each underwriter, if any, and each Person who controls any underwriter, of the
Registrable Securities held by or issuable to such Holder, against all claims, losses, damages and liabilities (or actions in respect thereto) to which they may become subject under the Securities Act, the Exchange Act, or other federal or state law
arising out of or based on (A) any untrue statement (or alleged untrue statement) of a material fact contained in any Registration Statement, Prospectus, offering circular, free writing prospectus or other document incident to any such
registration, qualification, compliance or sale effected pursuant to this Article V, or based on any omission (or alleged omission) to state therein a material fact required to be stated therein or necessary to make the statements therein not
misleading, (B) any violation or alleged violation by the Company of any federal, state or common law rule or regulation applicable to the Company in connection with any such registration, qualification, compliance or sale, or (C) any
failure to register or qualify Registrable Securities in any state where the Company or its agents have affirmatively undertaken or agreed in writing that the Company (including pursuant to Section 5.6(k)) that the Company
(the undertaking of any underwriter in connection with any such offering of Registrable Securities being attributed to the Company) will undertake such registration or qualification on behalf of the Holders of such Registrable Securities
(provided that in such instance the Company shall not be so liable if it has undertaken its reasonable best efforts to so register or qualify such Registrable Securities) and will reimburse, as incurred, each such Holder, each such
underwriter and each such director, officer, trustee, employee, partner, manager, member, stockholder, beneficiary, affiliate, agent and controlling person, for any legal and any other expenses reasonably incurred in connection with investigating or
defending any such claim, loss, damage, liability or action; provided that the Company will not be liable in any such case to the extent that any such claim, loss, damage, liability or expense arises out of or is based on any untrue statement
or omission made in reliance and in conformity with written information furnished to the Company by such Holder or underwriter expressly for use therein. 

(b) Each Holder (if Registrable Securities held by or issuable to such Holder are included in such registration, qualification, compliance or
sale pursuant to this Article V) does hereby undertake (severally and not jointly) to indemnify and hold harmless the Company, each of its officers, directors, employees, stockholders, affiliates and agents and each Person, if any, who
controls the Company within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act, each underwriter, if any, and each Person who controls any underwriter of the Registrable Securities covered by such a
Registration Statement, and each other Holder, each of such other Holder’s officers, directors, trustees, employees, partners, managers, members, stockholders, beneficiaries, affiliates and agents and each Person, if any, who controls such
Holder within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act, against all claims, losses, damages and liabilities (or actions in respect thereof) arising out of or based on any untrue statement (or
alleged untrue statement) of a material fact contained in any such Registration Statement, Prospectus, offering circular, free writing prospectus or other document, or any omission (or alleged omission) to state therein a material fact required to
be stated therein or necessary to make the statements therein not misleading, and will reimburse, as incurred, the Company, each such underwriter, each such other Holder, and each such officer, director, trustee, employee, partner, manager, member,
stockholder, beneficiary, affiliate, agent 

  
 49 

 
and controlling person of the foregoing, for any legal or any other expenses reasonably incurred in connection with investigating or defending any such claim, loss, damage, liability or action,
in each case to the extent, but only to the extent, that such untrue statement (or alleged untrue statement) or omission (or alleged omission) was made in such Registration Statement, Prospectus, offering circular, free writing prospectus or other
document, in reliance upon and in conformity with written information relating to such Holder furnished to the Company by such Holder expressly for use therein; provided, however, that the aggregate liability of each Holder hereunder
shall be limited to the proceeds (after underwriting discounts and commissions) received by such Holder upon the sale of the Registrable Securities giving rise to such indemnification obligation. It is understood and agreed that the indemnification
obligations of each Holder pursuant to any underwriting agreement entered into in connection with any Registration Statement shall be limited to the obligations contained in this Section 5.7(b). 

(c) Each party entitled to indemnification under this Section 5.7 (the “Indemnified Party”)
shall give notice to the party required to provide such indemnification (the “Indemnifying Party”) of any claim as to which indemnification may be sought promptly after such Indemnified Party has actual knowledge thereof, and
shall permit the Indemnifying Party to assume the defense of any such claim or any litigation resulting therefrom; provided that counsel for the Indemnifying Party, who shall conduct the defense of such claim or litigation, shall be subject
to approval by the Indemnified Party (whose approval shall not be unreasonably withheld) and the Indemnified Party may participate in such defense at the Indemnifying Party’s expense if representation of such Indemnified Party would be
inappropriate due to actual or potential differing interests between such Indemnified Party and any other party represented by such counsel in such proceeding; and provided, further, that the failure of any Indemnified Party to give notice as
provided herein shall not relieve the Indemnifying Party of its obligations under this Article V, except to the extent that such failure to give notice materially prejudices the Indemnifying Party in the defense of any such claim or any such
litigation. An Indemnifying Party, in the defense of any such claim or litigation, may, without the consent of each Indemnified Party, consent to entry of any judgment or enter into any settlement if and only if it (i) includes as a term
thereof the giving by the claimant or plaintiff therein to such Indemnified Party of an unconditional release from all liability with respect to such claim or litigation and (ii) does not include a statement as to or an admission of fault,
culpability or a failure to act by or on behalf of such Indemnified Party, and provided that any sums payable in connection with such settlement are paid in full by the Indemnifying Party. 

(d) In order to provide for just and equitable contribution in case the indemnification contemplated by
Section 5.7(a) or Section 5.7(b) is prohibited or limited by law, the Indemnifying Party, in lieu of indemnifying such Indemnified Party, shall contribute to the amount paid or payable by such
Indemnified Party as a result of such losses, claims, damages or liabilities in such proportion as is appropriate to reflect the relative fault of the Indemnifying Party and Indemnified Party in connection with the actions which resulted in such
losses, claims, damages or liabilities, as well as any other relevant equitable considerations. The relative fault of such Indemnifying Party and Indemnified Party shall be determined by reference to, among other things, whether any action in
question, including any untrue or alleged untrue statement of material fact or omission or alleged omission to state a material fact, has been made by, or relates to information supplied by, such Indemnifying Party or Indemnified Party, and such
Party’s relative intent, knowledge, access to information and opportunity to correct or prevent such actions;  

  
 50 

 
provided, however, that, in any case, (i) no Holder will be required to contribute any amount in excess of the proceeds (after underwriting discounts and commissions) received
by such Holder upon the sale of the Registrable Securities giving rise to such contribution obligation and (ii) no Person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) will be entitled
to contribution from any Person who was not guilty of fraudulent misrepresentation. The parties hereto agree that it would not be just or equitable if contribution pursuant to this Section 5.7(d) were determined by pro rata
allocation or by any other method of allocation that does not take account of the equitable considerations referred to in this Section 5.7(d). For the avoidance of doubt, it is understood that if and to the extent
indemnification is available under this Section 5.7, the Indemnifying Parties shall indemnify each Indemnified Party to the full extent provided in Section 5.7(a) and
Section 5.7(b) hereof without regard to the provisions of this Section 5.7(d). 
 (e) The
indemnities and contribution provided in this Section 5.7 shall survive the transfer of any Registrable Securities by such Holder. 

Section 5.8 Information by Holder. The Holder or Holders of Registrable Securities included in any registration shall furnish to
the Company such information regarding such Holder or Holders and the distribution proposed by such Holder or Holders as the Company may reasonably request in writing and as shall be required in connection with any registration, qualification or
compliance referred to in this Article V. 
 Section 5.9 Transfer of Registration Rights. The rights contained in
Section 5.2, Section 5.3 or Section 5.4 hereof to cause the Company to register the Registrable Securities may be assigned or otherwise conveyed by a Holder pursuant to a
Transfer of Shares or Options solely if and to the extent such Transfer is permitted under Article IV. Any assigned or conveyance in derogation of the foregoing shall be null and void ab initio. 

Section 5.10 Delay of Registration. No Holder shall have any right to obtain, and hereby waives any right to seek, an injunction
restraining or otherwise delaying any such registration as the result of any controversy that might arise with respect to the interpretation or implementation of this Article V. 

Section 5.11 Limitations on Subsequent Registration Rights. The Company shall not, without the prior written consent of all
Sponsors, enter into any agreement with any holder or prospective holder of any Equity Securities of the Company that would allow such holder or prospective holder to (a) require the Company to effect a registration or (b) include any
Shares in any registration filed under Section 5.2, Section 5.3 or Section 5.4 hereof, unless, in each case, under the terms of such agreement, such holder or prospective
holder may include such Shares in any such registration only to the extent that the inclusion of such Share will not diminish the amount of Registrable Securities that are included in such registration. 

Section 5.12 Rule 144 Reporting. With a view to making available to the Holders the benefits of certain rules and regulations of
the SEC that may permit the sale of the Registrable Securities to the public without registration, the Company, following an IPO, agrees to use its reasonable best efforts to: 

(a) make and keep current public information available, within the meaning of Rule 144, at all times after it has become subject to the
reporting requirements of the Exchange Act; 

  
 51 

 (b) file with the SEC, in a timely manner, all reports and other documents required of the
Company under the Securities Act and Exchange Act (after it has become subject to such reporting requirements); and 
 (c) so long as a
Holder owns any Registrable Securities, furnish to such Holder forthwith upon request a written statement by the Company as to its compliance with the reporting requirements of said Rule 144 (at any time commencing ninety (90) days after the
effective date of the first registration filed by the Company for an offering of its Securities to the general public), the Securities Act and the Exchange Act (at any time after it has become subject to such reporting requirements), a copy of the
most recent annual or quarterly report of the Company and such other reports and documents as a Holder may reasonably request in availing itself of any rule or regulation of the SEC allowing it to sell any such Securities without registration. 

Section 5.13 “Market Stand Off” Agreement. Each Holder hereby agrees that during such period (which
period shall in no event exceed (x) in the case of an IPO, one hundred eighty (180) days or (y) otherwise, ninety (90) days) following the effective date of a Registration Statement of the Company filed under the Securities Act
with respect to an IPO or any registration in which any Sponsor Holder is participating (or with respect to which all Sponsors agree in writing that this Section 5.13 should apply) (or, if later in the case of an Marketed
Underwritten Shelf Take-Down, the date the underwriting agreement for such Marketed Underwritten Shelf Take-Down is entered into) as requested by the Company or any underwriter or underwriters of such underwritten offering, such Holder and its
Affiliates shall not, to the extent requested by the Company and/or any underwriter, sell, pledge, hypothecate, transfer, make any short sale of, loan, grant any option or right to purchase of, or otherwise transfer or dispose of (other than to
donees who agree to be similarly bound), or enter into any transaction which is designed to, or might reasonably be expected to, result in the disposition of (whether by actual disposition or effective economic disposition due to cash settlement or
otherwise), any Shares, Options or other securities exercisable or exchangeable for, or convertible into, Shares, in each case held by it at any time during such period, except for Shares included in such registration; provided that any
release from such agreement shall be effected among the Holders on a pro rata basis according to the Shares then Beneficially Owned by them. Each Holder agrees that it shall deliver to the underwriter or underwriters of any offering to which clause
(i) or (ii) is applicable a customary agreement reflecting its agreement set forth in this Section 5.13. 

Section 5.14 Termination of Registration Rights. The rights of any particular Holder to cause the Company to register Registrable
Securities under Section 5.2, Section 5.3 or Section 5.4 hereof shall terminate as to any Holder on the date such Holder no longer holds any Registrable Securities.

ARTICLE VIII 

INDEMNIFICATION 

Section 8.1 Indemnification of Financial Investors. The Company will, and will cause their respective Subsidiaries to, jointly and
severally, indemnify, exonerate and hold the Financial Investors and each of their respective partners, stockholders, members, Affiliates, directors, officers, fiduciaries, managers, controlling Persons, employees and agents and each of the
partners, stockholders, members, Affiliates, directors, officers, fiduciaries, managers, controlling Persons, employees and agents of each of the foregoing (collectively, the “Indemnitees”) free and harmless from and against
any and all liabilities, losses, damages and costs and out-of-pocket expenses in connection therewith (including reasonable attorneys’ fees and expenses) incurred
by the Indemnitees or any of them before or after the Closing (collectively, the “Indemnified Liabilities”), arising out of any action, cause of action, suit, litigation, investigation, inquiry, arbitration or claim by any
Person (other than the Company or any of its Subsidiaries) against any Indemnitee (each, an “Action”) arising directly or indirectly out of, or in any way relating to, (i) any actual or alleged fiduciary or similar
duties to the Company, any of its Subsidiaries (including Jaguar I) or their respective current or former stockholders arising from 

  
 54 

 
such Financial Investor’s, or its Affiliates’ ownership of Shares or other securities of the Company or any of its Subsidiaries or such Financial Investor’s, or its
Affiliates’ control or ability to influence the Company or any of its Subsidiaries (other than any such Indemnified Liabilities (x) to the extent such Indemnified Liabilities arise out of any breach of this Agreement by such Indemnitee or
its Affiliates or other related Persons or the breach of any fiduciary or other duty or obligation of such Indemnitee to its direct or indirect equity holders, creditors or Affiliates or (y) to the extent such control or the ability to control
the Company or any of its Subsidiaries derives from such Financial Investors’ or its Affiliates’ capacity as an officer or director of the Company or any of its Subsidiaries) or (ii) the business, operations, properties, assets or
other rights or liabilities of the Company or any of its Subsidiaries. The Company will, and will cause its Subsidiaries to, jointly and severally, reimburse any Indemnitee for all reasonable costs and expenses (including reasonable attorneys’
fees and expenses and any other litigation-related expenses) as they are incurred in connection with investigating, preparing, pursuing, defending or assisting in the defense of any Action for which the Indemnitee would be entitled to
indemnification under the terms of this Article VIII, or any action or proceeding arising therefrom, whether or not such Indemnitee is a party thereto. The Company or its Subsidiaries, in the defense of any Action for which an Indemnitee
would be entitled to indemnification under the terms of this Article VIII, may, without the consent of such Indemnitee (which consent shall not be unreasonably withheld), consent to entry of any judgment or enter into any settlement if and
only if it (i) includes as a term thereof the giving by the claimant or plaintiff therein to such Indemnitee of an unconditional release from all liability with respect to such Action and (ii) does not include a statement as to or an
admission of fault, culpability or a failure to act by or on behalf of such Indemnitee, and provided that any sums payable in connection with such settlement are paid in full by the Company and/or its Subsidiaries. Notwithstanding anything to the
contrary set forth herein, in no event shall the Company or any of its Subsidiaries have any liability to any Indemnitee for any Indemnified Liabilities arising from any failure of the Company or any of its Subsidiaries to agree to any conditions,
restrictions, obligations or requirements in connection with applicable antitrust laws, except to the extent such failure arises in connection with a transaction in which the Company or any of its Subsidiaries is a party and, with respect to any
antitrust filing or approval for such transaction, does not involve the failure of such Indemnitee or one or more of its applicable Financial Investors or their Affiliates to properly and timely make any such required filing, or provide accurate and
not misleading information to, any governmental antitrust authority. 
 Section 8.2 Jointly Indemnifiable Claims. The Company
acknowledges and agrees that the Company shall, and to the extent applicable shall cause its Subsidiaries to, be fully and primarily responsible for the payment to the Indemnitee in respect of Indemnified Liabilities in connection with any Jointly
Indemnifiable Claims (as defined below), pursuant to and in accordance with (as applicable) the terms of (i) the Delaware General Corporation Law, as amended, (ii) the certificate of incorporation, as amended, of the Company,
(iii) the bylaws, as amended, of the Company, (iv) any director indemnification agreement, (v) this Agreement, (vi) any other agreement between the Company or any Subsidiary and the Indemnitee pursuant to which the Indemnitee is
indemnified, (vii) the laws of the jurisdiction of incorporation or organization of any Subsidiary of the Company and/or (viii) the certificate of incorporation, certificate of organization, bylaws, partnership agreement, operating
agreement, certificate of formation, certificate of limited partnership or other organizational or governing documents of any Subsidiary of the Company ((i) through (viii) collectively, the “Indemnification Sources”),
irrespective of any right of recovery the Indemnitee may have from any corporation, limited 

  
 55 

 liability company, partnership, joint venture, trust, employee benefit plan or other enterprise (other than
the Company, any of its Subsidiaries or the insurer under and pursuant to an insurance policy of the Company or any of its Subsidiaries) from whom an Indemnitee may be entitled to indemnification with respect to which, in whole or in part, the
Company or any of its Subsidiaries may also have an indemnification obligation (collectively, the “Indemnitee-Related Entities”). Under no circumstance shall the Company or any of its Subsidiaries be entitled to any right of
subrogation or contribution by the Indemnitee-Related Entities and no right of advancement or recovery the Indemnitee may have from the Indemnitee-Related Entities shall reduce or otherwise alter the rights of the Indemnitee or the obligations of
the Company or any of its Subsidiaries under the Indemnification Sources. In the event that any of the Indemnitee-Related Entities shall make any payment to the Indemnitee in respect of indemnification with respect to any Jointly Indemnifiable
Claim, (x) the Company shall, and to the extent applicable shall cause the Controlled Entities to, reimburse the Indemnitee-Related Entity making such payment to the extent of such payment promptly upon written demand from such
Indemnitee-Related Entity, (y) to the extent not previously and fully reimbursed by the Company and/or any of its Subsidiaries pursuant to clause (x), the Indemnitee-Related Entity making such payment shall be subrogated to the extent of the
outstanding balance of such payment to all of the rights of recovery of the Indemnitee against the Company and/or any of its Subsidiaries, as applicable, and (z) Indemnitee shall execute all papers reasonably required and shall do all things
that may be reasonably necessary to secure such rights, including the execution of such documents as may be necessary to enable the Indemnitee-Related Entities effectively to bring suit to enforce such rights. The Company and Indemnitee agree that
each of the Indemnitee-Related Entities shall be third-party beneficiaries with respect to this Section 8.2, entitled to enforce this Section 8.2 as though each such Indemnitee-Related Entity were
a party to this Agreement. The Company shall cause each of the Controlled Entities to perform the terms and obligations of this Section 8.2 as though each such Subsidiary was a party to this Agreement. For purposes of this
Section 8.2, the term “Jointly Indemnifiable Claims” shall be broadly construed and shall include any Indemnified Liabilities for which the Indemnitee shall be entitled to indemnification from both
(1) the Company and/or any of its Subsidiaries pursuant to the Indemnification Sources, on the one hand, and (2) any Indemnitee-Related Entity pursuant to any other agreement between any Indemnitee-Related Entity and the Indemnitee
pursuant to which the Indemnitee is indemnified, the laws of the jurisdiction of incorporation or organization of any Indemnitee-Related Entity and/or the certificate of incorporation, certificate of organization, bylaws, partnership agreement,
operating agreement, certificate of formation, certificate of limited partnership or other organizational or governing documents of any Indemnitee-Related Entity, on the other hand. 

Section 8.3 Non-Exclusive Right. The rights of any Indemnitee to indemnification this
Article VIII will be in addition to any other rights any such Person may have under any other Section of this Agreement (including Section 5.7) or any other agreement or instrument to which such Indemnitee is or
becomes a party or is or otherwise becomes a beneficiary or under law or regulation or under the certificate of incorporation or bylaws (or equivalent governing documents) of the Company or any of its Subsidiaries.

Section 10.1 Call Right.  

(a) Except as otherwise agreed to by the Sponsors and a Manager, with respect to all Shares and all other Equity Securities held by a Manager
(“Applicable Shares”), as applicable, (i) in connection with any Termination of Service, during the period beginning on the date of a Termination of Service of such Manager’s Applicable Employee and ending on the
first anniversary of the later of (a) the date of such Termination of Service or (b) as applicable, the date of the last exercise, exchange or conversion of any portion of any Options or other Equity Securities held by the Manager, or
(ii) in connection with any Restrictive Covenant Breach, during the period beginning on the date of such Restrictive Covenant Breach and ending on the first anniversary of such date (as applicable, the “Repurchase
Period”), the Company have the option (the “Call Right”) to repurchase the Manager’s Applicable Shares on the terms and subject to the conditions set forth in this Article X. The Call Right may be
exercised more than once and for some or all of the Applicable Shares held by the Manager. 
 Section 10.2 Exercise of Call
Right. The Company shall exercise the Call Right (if so elected) by written notice to the Manager within the Repurchase Period, specifying a date within such period on which the Call Right shall be exercised and the number of Shares as to which
the Call Right is being exercised. Upon such notification, the Manager shall promptly surrender to the Company any certificates representing the Shares being purchased, together with a duly executed stock power for the transfer of such Shares to
Company, free and clear of any Encumbrances. Except as provided below, upon the Company’s receipt of the certificates from the Manager, the Company shall deliver to him, her or it payment of the Repurchase Price (as defined below) for the
Shares being purchased. 
 Section 10.3 Repurchase Price. The purchase price payable by the Company upon exercise of the Call
Right (the “Repurchase Price”) will be as follows: 
 (a) In the event of any Termination of Service other than a
Termination of Service by the Company for Cause, the Fair Market Value, as of the date the Call Right is being exercised, of the Shares with respect to which the Call Right is being exercised; and 

(b) In the event of any Termination of Service by the Company for Cause, or in connection with any Restrictive Covenant Breach, the lesser of
(i) the Fair Market Value, as of the date the Call Right is being exercised, of the Shares with respect to which the Call Right is being exercised and (ii) the aggregate purchase price paid for such Shares by the Manager’s Applicable
Employee, as proportionately adjusted for any splits, reverse stock splits, combinations, recapitalizations or similar transactions (which price shall be zero for any Shares that were formerly Restricted Shares). 

  
 57 

 Section 10.4 Repurchase Notes. In the sole discretion of the Company Board, the
Company may pay the Repurchase Price in cash, check or by issuing a promissory note (a “Repurchase Note”) to Manager in the amount of the Repurchase Price. The Repurchase Note shall (a) bear simple interest at the prime
rate as published in The Wall Street Journal on the date such payment is due and owing from such date to the date such payment is made and (b) have such other reasonable terms and conditions as may be determined by the Company. All payments of
interest accrued under the promissory note shall be paid only at the date of payment by the Company of the principal amount of such promissory note. 

Section 10.5 Extension of Repurchase Period. Notwithstanding anything herein to the contrary, no payment shall be made under this
Article X if such payment (or the direct or indirect distribution to the Company by its Subsidiaries of the cash necessary to make such payment) would (i) cause the Company or its Subsidiaries to violate any applicable law, or any rights
or preference of preferred stockholders of the Company, (ii) violate the terms of any banking agreement or loan or other financial covenant of any indebtedness of the Company or its Subsidiaries or (iii) in the good faith judgment of the
Company’s Board of Directors, be reasonably likely to result in the Company or its Subsidiaries not retaining sufficient restricted payment capacity under the terms of any credit agreement, indenture, note or other operative agreement relating
to indebtedness of the Company or its Subsidiaries to permit interest payments with respect to the Debt Financing (as defined in the Merger Agreement) to be paid entirely in cash, in each case, regardless of when such agreement, loan, financial
covenant, indebtedness, indenture, note or operative agreement was created, incurred or assumed. Any payment under this Section that would cause such violation or default shall result in an extension of the Repurchase Period, in the sole discretion
of the Company, until such payment shall no longer cause any such violation or default and at which time the Call Right may be exercised. 

Section 10.6 [Reserved].

 60

effort to agree upon a suitable and equitable substitute provision to effect the original intent of the parties. 
 Section 11.3
Entire Agreement; Third Party Beneficiaries. Except as otherwise expressly set forth herein, this Agreement, together with the several agreements and other documents and instruments referred to herein or annexed hereto, embody the complete
agreement and understanding among the parties hereto with respect to the subject matter hereof and supersede and preempt any prior understandings, agreements or representations by or among the parties, written or oral, that may have related to the
subject matter hereof in any way. Without limiting the generality of the foregoing, to the extent that any of the terms hereof are inconsistent with the terms of any other agreement among the parties, the terms of this Agreement shall govern;
provided, that if the terms hereof are inconsistent with the terms of a Manager Side Agreement, the terms of such Manager Side Agreement shall govern with respect to the Manager that is party to such Manager Side Agreement. Except for
Section 2.1(e), Section 5.7, Section 7.4, Article VIII, Section 11.14, Section 11.16, and this
Section 11.3 (which will be for the benefit of the applicable Persons set forth therein, and any such Person will have the rights provided for therein), this Agreement does not create any rights, claims or benefits inuring
to any Person that is not a party hereto, and it does not create or establish any third party beneficiary hereto.

Successors and Assign; Assignments. Except as otherwise provided in this Agreement to the contrary, this Agreement shall be binding upon and inure to the benefit of the Stockholders, their distributees, heirs, legal representatives,
executors, administrators, successors and permitted assigns. The rights and obligations hereunder shall not be assignable without the prior written consent of all the Sponsors, except as otherwise expressly set forth herein subject, in each case, to
the limitations contained herein; provided that, (i) except as otherwise expressly set forth herein, a party may assign this Agreement in whole or in part to its Permitted Transferees in connection with any Transfer of Shares to such

this Agreement be assigned in whole or in part to any Carlyle Co-Investor Entity) and (ii) notwithstanding anything herein to the contrary, a Sponsor Investor may assign to any other member of its Sponsor
Investor Group any rights hereunder as an Eligible Tag-Along Stockholder under Section 4.4 or as a Holder under Article V. Any assignment of rights or obligations in violation
of this Section 11.4 shall be null and void. 

  
 61 

 Section 11.5 Counterparts. This Agreement may be executed in separate
counterparts each of which shall be an original and all of which taken together shall constitute one and the same agreement. 

Section 11.6 Remedies. 

(a) Each party hereto acknowledges that monetary damages would not be an adequate remedy in the event that each and every one of the covenants
or agreements in this Agreement is not performed in accordance with its terms, and it is therefore agreed that, in addition to and without limiting any other remedy or right it may have (but subject to the limitations set forth in
Section 5.10), the non-breaching party will have the right to an injunction, temporary restraining order or other equitable relief in any court of competent jurisdiction enjoining any
such breach and enforcing specifically each and every one of the terms and provisions hereof. Each party hereto agrees not to oppose the granting of such relief in the event a court determines that such a breach has occurred, and to waive any
requirement for the securing or posting of any bond in connection with such remedy. 
 (b) All rights, powers and remedies provided under
this Agreement or otherwise available in respect hereof at law or in equity shall be cumulative and not alternative, and the exercise or beginning of the exercise of any thereof by any party shall not preclude the simultaneous or later exercise of
any other such right, power or remedy by such party. 
 Section 11.7 Notices. All notices and other communications hereunder
shall be in writing and shall be deemed given if delivered personally, telecopied or emailed (upon telephonic confirmation or written confirmation (other than an automatically generated written reply) of receipt), on the first Business Day following
the date of dispatch if delivered by a recognized next day courier service, or on the third Business Day following the date of mailing if delivered by registered or certified mail, return receipt requested, postage prepaid; provided, however, that

 Section 11.8
Governing Law; Consent to Jurisdiction. 
 (a) This Agreement shall be governed by and construed in accordance with the laws of the
State of Delaware (without regard to conflict of laws principles to the extent they would result in the application of any other Law). The parties hereto agree that any suit, action or proceeding (“Litigation”) seeking to
enforce any provision of, or based on any matter arising out of or in connection with, this Agreement or the transactions contemplated hereby shall be brought in any federal court located in the State of Delaware or any Delaware state court. Each of
the parties hereto hereby irrevocably and unconditionally waives, and agrees not to assert, by way of motion, as a defense, counterclaim or otherwise, in any such Litigation, the defense of sovereign immunity, any claim that it is not personally
subject to the jurisdiction of the aforesaid courts for any reason, other than the failure to serve process in accordance with this Section 11.8(a), that it or its property is exempt or immune from jurisdiction of any such
court or from any legal process commenced in such courts (whether through service of notice, attachment prior to judgment, attachment in aid of execution of judgment, execution of judgment or otherwise), and to the fullest extent permitted by
applicable law, that the Litigation in any such court is brought in an inconvenient forum, that the venue of such Litigation is improper, or that this Agreement, or the subject matter hereof, may not be enforced in or by such particular courts and
further irrevocably waives, to the fullest extent permitted by applicable law, the benefit of any defense that would hinder, fetter or delay the levy, execution or collection of any amount to which the party is entitled pursuant to the final
judgment of any court having jurisdiction. 

  
 65 

 (b) Each of the parties hereto irrevocably consents to the service of process out of any of
the aforementioned courts in any such Litigation by the mailing of copies thereof by registered mail, postage prepaid, to such party at its address set forth in this Agreement, such service of process to be effective upon acknowledgment of receipt
of such registered mail. 
 (c) The parties hereto each expressly acknowledge that the foregoing waivers are intended to be irrevocable under
the laws of the State of Delaware and of the United States of America; provided that consent by the parties hereto to jurisdiction and service contained in this Section 11.8 is solely for the purpose referred to in
this Section 11.8 and shall not be deemed to be a general submission to said courts or in the State of Delaware other than for such purpose. 

Section 11.9 Waiver of Jury Trial. EACH PARTY ACKNOWLEDGES AND AGREES THAT ANY CONTROVERSY WHICH MAY ARISE UNDER THIS AGREEMENT IS
LIKELY TO INVOLVE COMPLICATED AND DIFFICULT ISSUES, AND THEREFORE SUCH PARTY HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES ANY RIGHT SUCH PARTY MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION DIRECTLY OR INDIRECTLY ARISING OUT OF OR
RELATING TO THIS AGREEMENT, OR THE TRANSACTIONS CONTEMPLATED BY THIS AGREEMENT. EACH PARTY CERTIFIES AND ACKNOWLEDGES THAT (i) NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER

Section 7.4, Section 11.16 and Article VIII shall survive any termination of this Agreement or the expiration or termination of any such provision.

such member of such Manager Group is hereby deemed to have so designated and appointed) such Manager Group Representative, as the sole representative of such Manager Group under this Agreement, with sole power and authority to exercise all rights of
the members of the such Manager Group hereunder and to perform all such acts as are required, authorized or contemplated by this Agreement to be performed by any member of such Manager Group under this Agreement, including delivering any notice or

members of such Manager Group, provided that notice thereof is given by such new Manager Group Representative to the Company. Without limiting the generality of the foregoing, with respect to each Manager Group, each member of such Manager Group
hereby irrevocably makes, constitutes and appoints (and each Permitted Transferee of such member is hereby deemed to have so made, constituted and appointed) the Applicable Employee of such Manager Group (and each successor to such Manager Group
Representative) the true and lawful attorney-in-fact of such member (or such Permitted Transferee), with full power and authority, for, on behalf of and in the name of
such member (or such Permitted Transferee) to execute and deliver on behalf of such member (or such Permitted Transferee) any and all instruments, agreements, notices, consents and other documents that are necessary or advisable to exercise the
rights and perform the acts contemplated by this Section 11.14. 
 Section 11.15 Aggregation of
Shares. All Shares Beneficially Owned by a Financial Investor Group or a Manager Group shall be aggregated together for purposes of determining the rights or obligations of any member of such Financial Investor Group or Manager Group, or
application of any restrictions to any member of such Financial Investor Group or Manager Group, under this Agreement, in each instance in which such right, obligation or restriction is determined by any ownership threshold. Within (i) each
Sponsor Investor Group, the applicable Sponsor, (ii) the Financial Investor Group comprised of the Blue Spectrum Entities, the Blue Spectrum Investor, (iii) the Financial Investor Group comprised of the GIC Entities, the GIC Investor, and
(iv) each Manager Group, the applicable Manager Group Representative, in each case, may allocate the ability to exercise any rights of the members of such Financial Investor Group or Manager Group under this Agreement (including any rights to
sell shares as an Eligible Tag-Along Stockholder or any rights to purchase Shares pursuant to Article X and any right to sell Registrable Securities pursuant to Article V) in any manner among the
members of such Financial Investor Group or Manager Group that such Sponsor, Blue Spectrum Investor, GIC Investor or Manager Group Representative, respectively, sees fit.

representation or warranty made in or in connection with this Agreement or as an inducement to enter into this Agreement), may be made only against the entities that are expressly identified as parties hereto; and no past, present or future
director, officer, employee, incorporator, member, partner, stockholder, Affiliate, agent, attorney or representative of any party hereto (including any Person negotiating or executing this Agreement on behalf of a party hereto), unless party to

performance of this Agreement (including a representation or warranty made in or in connection with this Agreement or as an inducement to enter into this Agreement).

action shall be deemed given if the record holders of a majority of the Shares held of record by the H&F Entities at such time provide such consent, approval or action in writing at such time.

shall be deemed given if the record holders of a majority of the Shares held of record by the Managers at such time provide such consent, approval or action in writing at such time. 

  
 68 

 Section 11.18 Several and not Joint. The obligations of each party under this
Agreement are several and not joint with the obligations of any other party, and no party shall be responsible in any way for the performance of the obligations of any other party under this Agreement. Nothing in this Agreement and no actions taken
by the parties under this Agreement shall be deemed to constitute the parties as, and the Company acknowledges that the parties do not so constitute, a partnership, association, a joint venture or other kind of group or co-operative entity between any of the parties, constitute any party the agent of any other party for any purpose, or create a presumption that the parties are in any way acting in concert or as a group or entity
with respect to such obligations or the transactions contemplated by this Agreement. 
 Section 11.19 Effectiveness. This
Agreement and the obligations of the Stockholders hereunder (and the amendment and restatement of the A&R Agreement pursuant hereto) shall become effective (the “Effective Time”) upon the execution and delivery of this

EAGLE HOLDING COMPANY I

 David
Simmons 
 Dear David: 
 Reference is made to
(i) the Stockholders Agreement, dated as of May 11, 2017 (the “Stockholders Agreement”), by and among Eagle Holding Company I, a Delaware corporation (together with any successor, the “Company”), Carlyle
Partners VI Holdings II, L.P., a Delaware limited partnership, Carlyle Partners VI, L.P., a Delaware limited partnership, CP VI Coinvestment A, L.P., a Delaware limited partnership, CP VI Coinvestment B, L.P., a Delaware limited partnership,
Hellman & Friedman Capital Partners VII, L.P., a Cayman Islands limited partnership, Hellman & Friedman Capital Partners VII (Parallel), L.P., a Cayman Islands limited partnership, HFCP VII
(Parallel-A), L.P., a Delaware limited partnership, and H&F Executives VII, L.P., a Cayman Islands limited partnership, Hellman & Friedman Capital Partners VIII, L.P., a Cayman Islands limited
partnership, Hellman & Friedman Capital Partners VIII (Parallel), L.P., a Cayman Islands limited partnership, HFCP VIII (Parallel-A), L.P., a Delaware limited partnership, H&F Executives VIII,
L.P., a Cayman Islands limited partnership, and H&F Associates VIII, L.P., a Cayman Islands limited partnership, Blue Spectrum ZA 2015 L.P., Clocktower Investment Pte Ltd., a Singaporean private limited company and any other Persons who become
parties thereto from time to time, to which you have become a party, effective as of the date hereof, (ii) the Stock Option Agreement, dated as of the date hereof, between you and the Company (the “Stock Option Agreement”),
(iii) the Eagle Holding Company I 2017 Equity Incentive Plan, dated as of the date hereof (the “Plan”), (iv) the Employment Agreement, dated as of May 17, 2012, by and among you, the Company and Pharmaceutical Product
Development, LLC, as may be amended from time to time in accordance therewith (the “Employment Agreement”) and (v) the Merger Agreement (as defined in the Stockholders Agreement). Capitalized terms used herein but not defined
herein shall have the meanings ascribed to them in the Stockholders Agreement and if such capitalized term does not have a meaning ascribed to it in the Stockholders Agreement, such term shall have the meaning ascribed to it in the Stock Option
Agreement or the Plan; provided, that “Change of Control Transaction” shall be as defined in the Stock Option Agreement. Notwithstanding anything herein to the contrary, (i) references to Shares or Options held or Beneficially
Owned by you shall also be deemed for purposes of the Stockholders Agreement and this letter agreement to include and apply to Shares or Options held or Beneficially Owned by the 2015 Simmons Family Gift Trust U/A June 18, 2015
(“Trust”) and any references herein to “you”, “your Shares”, “Tag-Along Stockholder”, “Participation Stockholder” and “your Registrable
Securities” shall be deemed to include, as appropriate, the Shares held by the Trust and such Shares shall be treated consistent with the treatment of your Shares pursuant to the Stockholders Agreement and this letter agreement and
(ii) the Trust shall constitute a member of your Manager Group and Shares and Options held or Beneficially Owned by the Trust shall be subject to the Call Right set out in Article X of the Stockholders Agreement (unless as otherwise agreed
pursuant to the terms of this letter agreement). 

 Notwithstanding anything to the contrary in the Stockholders Agreement, the undersigned
acknowledge and agree as follows: 
 1. Transfer Restrictions. Except as may be required by applicable law, the restrictions and
limitations set forth in Article IV of the Stockholders Agreement shall cease to apply to Transfers of Shares or Options held or Beneficially Owned by you upon the earliest to occur of (i) the one year anniversary of an IPO (subject to the
ability to dispose of Shares necessary to effect the cashless exercise of, or the net settlement of withholding taxes with respect to, any vested Options expiring during such one year period), (ii) a Liquidity Event that occurs prior to an IPO, and
(iii) a Change of Control Transaction provided that any securities you receive as consideration in such Change of Control Transaction are listed on a national stock exchange. 

2. Tag-Along Rights. In the event that you become a
Tag-Along Stockholder pursuant to Section 4.4 of the Stockholders Agreement, any Shares issuable in respect of vested Options held by you whether or not exercised (including any Options that would vest as
a result of the consummation of the Transfer to the Proposed Transferee) shall, at your sole discretion, be Tag-Along Shares and shall constitute Shares Beneficially Owned by you for purposes of determining
your Tag-Along Pro Rata Portion. Your rights set forth in Section 4.4 of the Stockholders Agreement shall terminate upon the earlier to occur of (i) the one year anniversary of an IPO and (ii) a
Liquidity Event that occurs prior to an IPO. With respect to Transfers subject to Section 4.4 of the Stockholders Agreement, if the form of consideration is not solely cash payable in immediately available funds or cash equivalents, you, in
your capacity as an Eligible Tag-Along Stockholder, may reasonably request financial and other information in order to reasonably evaluate the consideration proposed to be delivered. In the event that
(x) the consideration payable for Shares to be sold pursuant to Section 4.4 of the Stockholders Agreement includes securities and (y) applicable law would require the provision to you, in your capacity as an Eligible Tag-Along Stockholder or Tag-Along Stockholder, of any specified information regarding the Company or any of its parents or subsidiaries, such securities or the issuer thereof
that is not otherwise required to be provided for such Transfer pursuant to Section 4.4 of the Stockholders Agreement, then notwithstanding Section 4.4(c)(iv) of the Stockholders Agreement, you, in your capacity as a Tag-Along Stockholder, shall have the right to sell Shares in such proposed Transfer pursuant to Section 4.4 of the Stockholders Agreement; provided, that the Stockholder Sellers shall have the right,
but not the obligation, to cause to be paid to you, in your capacity as a Tag-Along Stockholder, in lieu of such securities described in the preceding sentence, an amount in cash equal to the Fair Market Value
of such Shares as of the date such securities otherwise would have been issued in exchange for such Shares. You will not be required to agree to a non-compete agreement as a condition to participating in a
Transfer as a Tag-Along Stockholder or otherwise in connection with such Transfer (it being understood that any existing non-compete agreement then in effect between you
and the Company or one of its parents or subsidiaries shall not terminate solely as a result of such Transfer). For the avoidance of doubt, you shall be deemed to be a Stockholder for purposes of the Stockholders Agreement as long as you hold vested
equity in the Company. 

  
 2 

 3. Drag-Along Right. In the event that you become a Participating Stockholder Seller
pursuant to Section 4.5 of the Stockholders Agreement, all Shares issuable in respect of vested “in the money” Options held by you whether or not exercised (including any Options that would vest as a result of the consummation of the
Change of Control Transaction) shall constitute Shares held by you for purposes of the calculation set forth in the first sentence of Section 4.5(a) of the Stockholders Agreement (provided, notwithstanding anything to the contrary in
Section 4.5 of the Stockholders Agreement, you shall be required to exercise only the applicable “in the money” Options with respect to such Shares in accordance therewith). In the event that (x) the consideration payable for
Shares to be sold pursuant to Section 4.5 of the Stockholders Agreement includes securities and (y) applicable law would require the provision to you, in your capacity as a Participating Stockholder Seller or Drag-Along Seller, as
applicable, of any specified information regarding the Company or any of its parents or subsidiaries, such securities or the issuer thereof that is not otherwise required to be provided for such Transfer pursuant to Section 4.5 of the
Stockholders Agreement, then notwithstanding Section 4.5(f) of the Stockholders Agreement, you, in your capacity as a Participating Stockholder Seller or Drag-Along Seller, as applicable, shall have the right to sell Shares in such proposed
Transfer pursuant to Section 4.5 of the Stockholders Agreement; provided, that the Sponsor Investor Sellers shall have the right, but not the obligation, to cause to be paid to you, in your capacity as a Drag-Along Seller, in lieu of
such securities described in the preceding sentence, an amount in cash equal to the Fair Market Value of such Shares as of the date such securities otherwise would have been issued in exchange for such Shares. The Drag-Along Right of the Sponsors
shall terminate upon the earlier to occur of (i) an IPO and (ii) a Liquidity Event. The Drag-Along Right of the Sponsors shall not include a right to require you to sign a non-compete agreement (it
being understood that any existing non-compete agreement then in effect between you and the Company or one of its parents or subsidiaries shall not terminate solely as a result of such Transfer). Any unvested
or “out-of-the money” vested Options shall be treated in accordance with the applicable award agreement. 

4. Participation Stockholder. With respect to each Post-Closing Issuance for which a Participation Notice is delivered pursuant to
Section 6.1 of the Stockholders Agreement, in the event that a Sponsor Investor elects to become an Accepting Participation Stockholder with respect to such Post-Closing Issuance, you will be entitled to participate in such Post-Closing
Issuance as a Participation Stockholder; provided, that if such Post-Closing Issuance is for shares of Voting Securities, the Company shall have the right to issue to you securities having the same economic terms and conditions as such Voting
Securities but without any voting rights. 
 5. Put Right. 

(a) In the event you incur a Termination of Service as a result of your death or by you for Good Reason, or a Termination of Service by the
Company or one of its parents or subsidiaries due to your Disability or without Cause (in each case in this letter agreement as defined in the Employment Agreement, including a notice of non-renewal of the
Term of the Employment Agreement by the Company or Pharmaceutical Product Development, LLC (or any successor thereto)), you or your guardian, executor, administrator, or applicable trustee generally having control over your Shares, including the
Trustee(s) of the Trust (the “Trustee”) shall have the right (the “Put Right”) to require that the Company purchase all, or any portion of, the Shares held by you or, if applicable, the Trustee and, subject to the
proviso in the immediately following sentence, Shares issuable in respect of vested Options held by you or, if applicable, the Trustee (whether or not exercised) on the terms described in this paragraph 5; provided, however, that

  
 3 

 
the Company will not be obligated to purchase any Put Securities (as defined below) if (i) such purchase (or the direct or indirect distribution to the Company by subsidiaries of the Company
of the cash necessary to make such purchase) (x) is prohibited by any applicable law or regulation, (y) would violate any financing agreement, indenture or similar document and, in this regard, the Company agrees that it will use
commercially reasonable efforts to not agree to such a restriction or permit any subsidiary to agree to such restriction unless such restriction is commercially reasonable in light of the contemplated transaction as determined by the Company in its
good faith, or (z) in the good faith determination of the Company’s Board of Directors is reasonably likely to result in the Company and its subsidiaries not retaining sufficient restricted payment capacity under the terms of any financing
agreement, indenture or similar document to permit interest payments with respect to outstanding indebtedness of the Company or any of its subsidiaries to be paid entirely in cash (in which event the Put Notice may only be effected once the
Company’s and its’ subsidiaries’ restricted payment capacity is sufficient to enable the Put) or (ii) the Company determines in good faith that the Company’s liquidity position is such that the repurchase of the Put
Securities would have or reasonably be expected to result in a material negative impact on the operations or financial position of the Company and its parents and subsidiaries (in which event the Put Notice may only be effected once the
Company’s liquidity position is sufficient to enable the Put). The Put Right shall be exercised by written notice (the “Put Notice”) to the Company given in accordance with Section 11.7 of the Stockholders Agreement on or
prior to the first anniversary of your Termination of Service, which Put Notice shall specify the number of Shares and Shares issuable in respect of vested Options that you or, if applicable, the Trustee is requesting that the Company purchase (the
“Put Securities”), provided, however, that if the Company reasonably determines that the repurchase of the Put Securities would otherwise result in any Options (including any Options held by other Service Providers)
being classified as a liability as contemplated by Financial Accounting Standards Board Accounting Standard Codification (ASC) Section 718, Compensation — Stock Compensation (FASB ASC 718), including any amendments and
interpretations thereto, the Put Right shall not apply to vested Options and any Shares that are to be purchased by the Company or its designee under paragraph 5 of this letter agreement may only be so purchased if and when such Shares have been
held by you or the Trustee, as applicable, for at least six months. Any such Put Notice shall be irrevocable. The parties hereto acknowledge and agree that the Company may, at its sole discretion, designate any other Person to purchase all or part
of the Put Securities in lieu of the Company in accordance with the time periods set forth in this paragraph 5. The purchase price payable by the Company or its designee (the “Put Purchase Price”) for the Put Securities shall be the
amount equal to the Fair Market Value of such Put Securities on the date of delivery of the Put Notice. 
 (b) Subject to the provisos to the
first and second sentences of paragraph 5(a), the purchase of the Put Securities shall take place on the later of (i) the date specified by the Company, which shall in no event be later than thirty (30) days following the determination of
the Fair Market Value of the Put Securities or, if the Company does not have sufficient liquidity or sufficient restricted payment capacity as set forth in paragraph 5(a)(i)(z), ten (10) days following the date its liquidity or restricted
payment capacity is sufficient to enable the Put, and (ii) within ten (10) days following the receipt by the Company of all necessary governmental approvals. On such date, you or, if applicable, the Trustee shall transfer the Put
Securities to the Company or its designee, free and clear of all liens and encumbrances, by delivering to the Company or its designee the certificates representing the Shares to be purchased, duly endorsed for transfer to the Company or its designee
or accompanied by a stock power duly executed in blank, and the Company or its designee shall pay to you or, if applicable, the Trustee the Put Purchase Price. 

  
 4 

 (c) The Company shall be entitled to deduct and withhold from any amounts payable to you or,
if applicable, the Trustee pursuant to this paragraph 5 such amounts as it is required to deduct and withhold under all applicable tax laws and such amounts so withheld shall be treated for all purposes of this letter agreement as having been paid
to you or the Trustee, as applicable. 
 (d) The Put Right shall terminate on the one year anniversary of an IPO. 

6. Call Right. 
 (a)
Notwithstanding anything to the contrary in Article X of the Stockholders Agreement, if (i) you incur a Termination of Service without Cause or by you for Good Reason, (ii) within six months following such Termination of Service, a
Qualifying Post-Termination Event is consummated and (iii) prior to the consummation of such Qualifying Post-Termination Event, Shares or other Equity Securities had been repurchased from you pursuant to Article X of the Stockholders Agreement,
you shall receive a cash payment equal to the excess (if any) of (x) the Fair Market Value of the consideration that would have been paid to you in respect of such Shares or other Equity Securities upon the consummation of the Qualifying
Post-Termination Event had such Shares or other Equity Securities not been repurchased pursuant to Article X of the Stockholders Agreement over (y) the consideration paid to you in respect of such repurchase of Shares pursuant to Article X of
the Stockholders Agreement. 
 (b) Notwithstanding anything to the contrary in Article X of the Stockholders Agreement, Article X shall
terminate in respect of Shares held by you upon the earlier to occur of a (i) Change of Control Transaction and (ii) an IPO. Notwithstanding any provisions of the Plan or any Option award agreement incorporating the terms of the Plan, the
Call Right provided in Article X of the Stockholders Agreement (as modified herein) shall exclusively govern, and any similar call rights established by the Plan or Option award agreement incorporating the terms of the Plan, will not be applicable.
For the avoidance of doubt, however, in the event of any Termination of Service in which Options may remain eligible to vest in the future (either as a result of a Qualifying Post-Termination Event or the occurrence of a subsequent Liquidity Event),
any Shares acquired upon the exercise of such Options following vesting shall be subject to repurchase under Article X of the Stockholders Agreement commencing on the date of exercise of any such Options and ending one year thereafter. 

(c) For purposes of the Stockholders Agreement and this letter agreement, (i) the covenants applicable for the determination of a
Restrictive Covenant Breach shall be limited to Sections 5(a) and (b) of your Employment Agreement, as in effect on the date hereof and (ii) no Restrictive Covenant Breach shall have occurred unless the applicable conduct continues
following the cure period described in the Stockholders Agreement. 

  
 5 

 (d) Notwithstanding anything in the Plan, the Stockholders Agreement or this letter
agreement to the contrary, in the event the Repurchase Period (as modified by this letter agreement) would otherwise expire prior to the later of (i) the 10th day after the last date any of the Principal Stockholders makes its determination of
the value of the Company as of the most recently completed calendar quarter for purposes of reporting such value to its limited partners (such date of determination, the “Quarterly Valuation Date”) or (ii) the date the
Independent Expert makes its determination of Fair Market Value (such date of determination, the “Expert Valuation Date”), the Repurchase Period shall automatically be extended until the 10th day after the Quarterly Valuation Date
or Expert Valuation Date, as applicable. Notwithstanding anything in the Stockholders Agreement (as modified by this letter agreement) or this letter agreement to the contrary, in the event of a Termination of Service in which
Section 2.1(b)(iii), Section 2.2(c), Section 2.3(c) or Section 2.5, in each case, of the Stock Option Agreement applies, then Shares issuable with respect to any Options that may become vested pursuant to such Sections (other
than Section 2.5 of the Stock Option Agreement) on or prior to a Change of Control Transaction or an IPO shall not be repurchased by the Company until such Options become vested and Shares issuable with respect to any Options that become vested
under Section 2.5 of the Stock Option Agreement on or prior to a Change of Control Transaction or an IPO shall not be repurchased by the Company until the earlier of the date such Options become vested or the first anniversary of your
Termination of Service. 
 (e) Notwithstanding anything in the Plan, the Stockholders Agreement or this letter agreement to the contrary, for
purposes of Section 10.3(b)(ii) of the Stockholders Agreement, the purchase price paid for each Share received by you pursuant to the Rollover Agreement entered into by you, dated as of April 26, 2017, shall be deemed to be $27.086 less
any amounts paid to you by way of dividends and/or distributions of any kind with respect to such Share (such price as proportionately adjusted for any stock split, reverse stock split or similar event with respect to the Shares occurring after the
Closing). 
 7. Fair Market Value; Dividend Payments. 

(a) Notwithstanding anything in the Plan, the Stockholders Agreement or this letter agreement to the contrary, in each case in which the term
“Fair Market Value” is used in the Stockholders Agreement or this letter agreement, it shall have the following meaning to the extent used with respect to you or your Shares or Options, except in the event of a Termination of Service for
Cause or in connection with a Restrictive Covenant Breach, (i) Fair Market Value shall be determined as of the last day of the most recently completed calendar quarter and without regard to any minority, illiquidity, lack of marketability or
similar discounts, (ii) in no event shall Fair Market Value be less than the average of the values of the Company determined by the Principal Stockholders and reported to the limited partners of the Principal Stockholders as of the last day of
the most recently completed calendar quarter, and (iii) in the event you disagree with the Company Board’s determination of Fair Market Value in accordance with the foregoing, you may request an independent third party to determine the
relevant Fair Market Value (the “Independent Expert”). The Independent Expert shall be selected by the Company from one of (a) a nationally recognized investment bank, (b) a nationally recognized accounting firm,
(c) a nationally recognized valuation expert or (d) Duff & Phelps Corporation, subject to your approval (such approval not to be unreasonably withheld or delayed in the case of an Independent Expert selected pursuant to clause
(a), (b), or (c)) and shall determine the relevant Fair Market Value within 30 business days of the date of its appointment, or such longer period as the Company and you may agree. The Independent Expert’s decision shall be (in the absence

  
 6 

 
of manifest error) final and binding on the parties hereto. In the event the Independent Expert determines that the relevant Fair Market Value is less than 110% of the value determined by the
Company Board in accordance with clauses (i) and (ii) of the first sentence of this Section 7(a), you shall pay all of the fees and expenses of the Independent Expert, failing which the Company shall pay all of the fees and expenses of the
Independent Expert. 
 (b) With respect to any dividend equivalents payable in respect of any unvested Options which remain unpaid at the
time of any Termination of Service (“Unvested Dividend Payments”), to the extent that any of such Termination of Service, a Qualifying Post-Termination Event or a subsequent Liquidity Event results in vesting of the Options to which
the Unvested Dividend Payments relate, such Unvested Dividend Payment shall be paid within five (5) business day following the date upon which the applicable Options vest. In addition, in the event you incur a Termination of Service as of
result of your death or by you for Good Reason, or a Termination of Service by the Company or one of its parents or subsidiaries due to your Disability or without Cause (including a notice of non-renewal of
the Term of the Employment Agreement by the Company or Pharmaceutical Product Development, LLC (or any successor thereto)), you or your Trustee (as defined in paragraph 5(a)) shall be paid the unvested dividend equivalents on any vested Options on
the 60th day following the date of such Termination of Service. 
 8. Definition of
“Same Terms and Conditions”. Notwithstanding clause (b) of the definition of “Same Terms and Conditions”, in any transaction in which you are to receive consideration on the Same Terms and Conditions as the Sponsor
Investors, the form of consideration paid to Sponsor Investors, on the one hand, and you, on the other hand, may (without your consent) differ only if payment of the same form of consideration (i) is not permitted by applicable law,
(ii) would require additional information disclosure to you that is not provided to the Sponsor Investors or (iii) would require additional disclosure to, or approvals or consents of, regulatory authorities that would not be required in
connection with the payment of such form of consideration to the Sponsor Investors; provided, that if such consideration is for shares of Voting Securities, you may receive securities having the same economic terms and conditions as such
Voting Securities but without any voting rights. 
 9. SEC Filings. The Company shall file a Registration Statement on Form S-8 (or its successor form), if then available, and which Registration Statement contains a “reoffer prospectus” naming you as a reseller of control securities (as such terms are defined in Instruction C
to the General Instructions to Form S-8) with the SEC no later than five (5) business days after the date of an IPO covering any Shares subject to the Option granted to you under the Stock Option
Agreement that have vested or remain eligible to vest as of such date. 
 10. Amendments. (a) No amendment or modification to the
Stockholders Agreement that adversely affects the Manager Groups shall be effective against the Manager Groups unless the Managers who are officers of the Company or its subsidiaries with a title of, and more senior to, Senior Vice President (the
“Senior Managers”), consent to such amendment or modification in writing, provided, that such consent will be effective at such time as the Senior Managers then holding a majority of Shares held by all Senior Managers provide
such consent, provided, further, that all outstanding vested Options of the Senior Managers shall be included as Shares for the purposes of the foregoing calculation. No amendment or modification

  
 7 

 
to the Stockholders Agreement that adversely affects your rights or obligations under the Stockholders Agreement in a manner that is materially disproportionate to the manner in which it
adversely affects the rights or obligations of the Senior Managers as a whole shall be effective against you unless you consent to such amendment or modification in writing. Notwithstanding any provision of this letter agreement to the contrary, in
no event shall this letter agreement be amended without your consent. 
 11. Termination. So long as you hold Shares or Options, no
termination of the Stockholders Agreement prior to the consummation of a Change of Control Transaction will be effective against you unless you consent to such termination in writing, provided, however, that a termination of the
Stockholders Agreement effective in connection with an IPO will be effective against you (whether or not you consent) if (i) your rights under Article V survive such termination or (ii) you are otherwise granted registration rights with
respect to your Registrable Securities that are not, in any material respect, less advantageous to you than your rights under Article V and provided, further, that in the event of an IPO that occurs after the termination of the
Stockholders Agreement but during which the transfer restrictions set forth in Article IV of the Stockholders Agreement (as amended by paragraph 1 of this letter agreement) continue to apply, then the rights set forth in Section 4.4 of the
Stockholders Agreement (as amended by paragraph 2 of this letter agreement) shall continue to apply until the earlier of (x) such transfer restrictions ceasing to apply and (y) the one year anniversary of such IPO. Nothing herein shall be
deemed to waive your rights under paragraph 9 of this letter agreement which shall survive any termination of the Stockholders Agreement. 

12. Certain Arbitration Matters. For the avoidance of doubt, notwithstanding paragraph 13 below, any dispute regarding the nature of
your Termination of Service, including, without limitation, whether “Cause” existed, shall be resolved for all purposes by arbitration proceedings in Wilmington, North Carolina in accordance with the arbitration terms and conditions set
forth in the Employment Agreement. 
 13. Miscellaneous; Incorporation by Reference. This letter agreement shall be deemed to amend
the Stockholders Agreement solely with respect to the matters set forth herein, and (subject to paragraph 10 above) in the event of any conflicts between this letter agreement and the Stockholders Agreement, this letter agreement will control
(notwithstanding the fact that you may execute the Stockholders Agreement after this letter agreement). Except as expressly amended herein, the Stockholders Agreement shall remain in full force and effect. Sections 11.2, 11.4, 11.5, 11.7, 11.8
(subject to paragraph 12 hereof), 11.9, 11.10, 11.11, 11.12 (subject to paragraph 11 hereof), 11.13 (subject to the terms of this letter agreement with respect to such subsequent Shares or Options) and 11.14 of the Stockholders Agreement are
incorporated by reference herein and shall apply to this letter agreement (and the Stockholders Agreement as amended hereby), mutatis mutandis. 

14. Company Representations. The Company represents and warrants to you that (i) the execution, delivery and performance of this
letter agreement has been fully and validly authorized by all necessary corporate actions, including any approvals required by the board of directors of the Company pursuant to the Stockholders Agreement, (ii) the officer signing this letter
agreement on behalf of the Company is duly authorized to do so and (iii) upon execution and delivery of this letter agreement by you and the Company, it shall be a valid and 

  
 8 

 
binding obligation of the Company enforceable against it in accordance with its terms, except to the extent that enforceability may be limited by applicable bankruptcy, insolvency, or similar
laws affecting the enforcement of creditors’ rights generally.
