performed, BMP shall be entitled to receive upon consummation of: 
 (i) any such acquisition, divestiture, disposition,
merger, consolidation, restructuring or recapitalization, a non-refundable and irrevocable fee equal to (x) 1% of the aggregate enterprise value of the acquired, divested, merged, consolidated, restructured or recapitalized entity (calculated,

financing or similar transaction, it will notify the Advisors of such determination in writing. Promptly thereafter, upon the request of BMP, the parties will negotiate in good faith to agree upon appropriate services, compensation and
indemnification for the Company or such subsidiary to hire BMP or one of its Affiliates for such services. The Company and its subsidiaries may not hire any person, other than BMP or one of its Affiliates, to perform any such services unless all of
the following conditions have been satisfied: (i) the parties are unable to agree upon the terms of the engagement of BMP or its Affiliate to render such services after 30 days following receipt by BMP of such written notice; (ii) such
other person has a reputation that is at least equal to the reputation of BMP or its Affiliate in respect of such services; (iii) ten business days have elapsed after the Company or such subsidiary provides a written notice to BMP of its
intention to hire such other person, which 

  

 3 

 
notice shall identify such other person and shall describe in reasonable detail the nature of the services to be provided, the compensation to be paid and
the indemnification to be provided; (iv) the compensation to be paid is not more than BMP or its Affiliate was willing to accept in the negotiations described above; and (v) the indemnification to be provided is not more favorable to the
Company or the applicable subsidiary than the indemnification that BMP or its affiliate was willing to accept in the negotiations described above. 
 SECTION 4. Advisory Fee. 
 (a) In consideration of the Services being rendered by the Advisors, the Company will
pay, or will cause to be paid, to the Advisors an annual non-refundable and irrevocable advisory fee (the “Advisory Fee”; the term “Advisory Fee” as used in this Agreement with respect to any annual period means all
amounts payable with respect to such annual period pursuant to Sections 4(b) or (c) hereof, as applicable; provided that notwithstanding anything to the contrary contained in this Agreement, the minimum annual Advisory Fee payable to the
Advisors shall be $10,000,000). 
 (b) The Advisory Fee for the year ending June 30, 2007 shall be equal to $2,219,200, which shall be
paid, or caused to be paid, by the Company at the Closing in respect of Services to be rendered from the Closing Date to June 30, 2007. 
 (c) The Advisory Fee for fiscal year 2008 and each subsequent year shall be equal to the greater of $10,000,000 or 3% of Consolidated EBITDA (as defined in the Credit Agreement dated as of April 10, 2007, by and among the Company;
Morgan Stanley Senior Funding, Inc. as administrative agent, collateral agent, swing line lender, joint lead arranger and joint bookrunner; Goldman Sachs Credit Partners L.P., as joint lead arranger, joint bookrunner and syndication agent; Bank of
America, NA., as joint bookrunner and co-documentation agent; Bear Stearns Corporate Lending Inc. as joint bookrunner and co-documentation agent; General Electric Capital Corporation, as co-documentation agent; and the lenders from time to time
party thereto). The Company will pay, or cause to be paid, to the Advisors, $10,000,000 on July 1, 2007, and thereafter on July 1 of each subsequent year. Following the preparation of the Company’s audited financial statements for
each fiscal year beginning with the fiscal year ending June 30, 2008, the Company shall calculate Consolidated EBITDA for such fiscal year. If 3% of Consolidated EBITDA for such year exceeds $10,000,000, the Company shall pay the Advisors the
amount of such excess. 
 (d) In the event the Company or any of its subsidiaries enters into a business combination transaction with another
entity that is large enough to constitute a “significant subsidiary” of the Company under any of the relevant tests contained in Regulation S-X as promulgated by the Securities and Exchange Commission, the Company and BMP will mutually
agree, following good faith negotiations, on an appropriate increase in the minimum annual Advisory Fee as warranted by the increase in the Company’s size. Such increase will be based on the percentage increase in the Company’s EBITDA
determined on a pro forma basis giving effect to such business combination transaction. 
 (e) To the extent the Company cannot pay, or cause
to be paid, the Advisory Fee for any reason, including by reason of any prohibition on such payment pursuant to any 

  

 4 

 
applicable law or the terms of any debt financing of the Company or its subsidiaries, the payment by the Company or any of its subsidiaries to the Advisors
of the accrued and payable Advisory Fee will be payable immediately on the earlier of (i) the first date on which the payment of such deferred Advisory Fee is no longer prohibited under any contract applicable to the Company and the Company or
its subsidiaries, as applicable, is otherwise able to make such payment, or cause such payment to be made, and (ii) total or partial liquidation, dissolution or winding up of the Company. Notwithstanding anything to the contrary herein, under
any applicable law or under any contract applicable to the Company or its subsidiaries, any forbearance of collection of the Advisory Fee by the Advisors shall not be deemed to be a subordination of such payments to any other person, entity or
creditor of the Company or its subsidiaries. Any such forbearance shall be at BMP’s sole option and discretion and shall in no way impair any Advisor’s right to collect such payments. Any installment of the Advisory Fee not paid on the
scheduled due date will bear interest, payable in cash on each scheduled due date, at an annual rate of 10%, compounded quarterly, from the date due until paid. 
 (f) Notwithstanding anything to the contrary contained in this Agreement, BMP may elect (on behalf of the Advisors) (in its sole discretion by the delivery of written notice to the Company) at any time in connection
with or in anticipation of a change of control of the Company, a sale of all or substantially all of the Company’s assets or an initial public offering of the equity of the Company or its successor (or at any time thereafter) to receive, in
consideration of the termination of the Services and for any remaining Advisory Fees payable by the Company under this Agreement and in addition to any fees owing to the BMP in connection with such transaction pursuant to Section 3(b) hereof, a
single lump sum non-refundable and irrevocable cash payment (the “Lump Sum Fee”) equal to the then present value (using a discount rate equal to the yield to maturity on the date of such written notice of the class of outstanding
U.S. government bonds having a final maturity closest to the tenth anniversary of the date of this agreement (the “Discount Rate”)) of all then current and future Advisory Fees payable under this Agreement, assuming the Termination
Date is the tenth anniversary of the date of such election. Promptly after the receipt of such written notice, the Company shall pay the Lump Sum Fee to the Advisors by wire transfer in same-day funds to the bank account or accounts designated by
the Advisors, which payment shall not be refundable under any circumstances. Following the payment of the Lump Sum Fee, the obligation of the Advisors to provide the Services hereunder, and the obligations of the Company to pay Advisory Fees, shall
be terminated, but all other provisions of this Agreement shall continue unaffected. 
 (g) To the extent the Company does not pay, or cause
to be paid, any portion of the Lump Sum Payment by reason of any prohibition on such payment pursuant to any applicable law, the terms of any agreement or indenture governing indebtedness of the Company or its subsidiaries, any unpaid portion of the
Lump Sum Payment shall be paid to the Advisors on the first date on which the payment of such unpaid amount is permitted under such agreement or indenture. Notwithstanding anything to the contrary herein, under any applicable law or under any
contract applicable to the Company or its subsidiaries, any forbearance of collection of the Lump Sum Fee by the Advisors shall not be deemed to be a subordination of such payments to any other person, entity or creditor of the Company or its
subsidiaries. Any such forbearance shall be at BMP’s sole option and discretion and shall in no way impair any Advisor’s right to collect such payments. Any portion of the Lump Sum Payment not paid on the scheduled due date shall bear
interest at an annual rate equal to the Discount Rate, compounded quarterly, from the date due until paid. 
  

 5 

 (h) Each of the Advisors shall receive its Pro Rata Share of the Advisory Fee and the Lump Sum Payment.

 SECTION 5. Reimbursements. In addition to the fees payable pursuant to this Agreement, the Company will pay, or cause to
be paid, directly, or reimburse the Advisors and each of their Affiliates for, their respective Out-of-Pocket Expenses (as defined below). For the purposes of this Agreement, the term “Out-of-Pocket Expenses” means the out-of-pocket
costs and expenses incurred by the advisors and their Affiliates in connection with the Transactions and the Services or other services provided by them under this Agreement (including prior to the Effective Time), or in order to make Securities and
Exchange Commission and other legally required filings relating to the ownership of equity securities of the Company or its successor by the Advisors or their Affiliates, or otherwise incurred by the Advisors or their Affiliates from time to time in
the future in connection with the ownership or subsequent sale or transfer by the Advisors or their Affiliates of capital stock of the Company or its successor, including, without limitation, (a) fees and disbursements of any independent
professionals and organizations, including independent accountants, outside legal counsel or consultants, retained by an Advisor or any of its Affiliates, (b) costs of any outside services or independent contractors such as financial printers,
couriers, business publications, on-line financial services or similar services, retained or used by an Advisor or any of its Affiliates, and (c) transportation, per diem costs, word processing expenses or any similar expense not associated

reimbursement in accordance with this Agreement, to the bank account indicated to the Company by the relevant payee. 
 SECTION 6. Indemnification. 
 The Company will indemnify and hold harmless the Advisors, their Affiliates and their
respective partners (both general and limited), members (both managing and otherwise), officers, directors, employees, agents and representatives (each such person being an “Indemnified Party”) from and against any and all actions,
suits, investigations, losses, claims, damages and liabilities, including in connection with seeking indemnification, whether joint or several (the “Liabilities”), related to, arising out of or in connection with the Services or
other services contemplated by this Agreement or the engagement of the Advisors pursuant to, and the performance by the Advisors of the Services or other services contemplated by, this Agreement, whether or not pending or threatened, whether or not
an Indemnified Party is a party, whether or not resulting in any liability and whether or not such action, claim, suit, investigation or proceeding is initiated or brought by the Company. The Company will reimburse any Indemnified Party 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, claim, suit, investigation or proceeding for which the Indemnified Party would be entitled to indemnification under the terms of the previous sentence, or any action or proceeding arising therefrom, whether or not such Indemnified Party is a
party thereto. The Company agrees that it will not, without the 

  

 6 

 
prior written consent of the Indemnified Party, settle, compromise or consent to the entry of any judgment in any pending or threatened claim, action or
proceeding relating to the matters contemplated hereby (if any Indemnified Party is a party thereto or has been threatened to be made a party thereto) unless such settlement, compromise or consent includes an unconditional release of the Indemnified
Party from all liability, without future obligation or prohibition on the part of the Indemnified Party, arising or that may arise out of such claim, action or proceeding, and does not contain an admission of guilt or liability on the part of the
Indemnified Party. The Company will not be liable under the foregoing indemnification provision with respect to any particular loss, claim, damage, liability, cost or expense of an Indemnified Party that is determined by a court, in a final judgment
from which no further appeal may be taken, to have resulted solely from the gross negligence or willful misconduct of such Indemnified Party. The attorneys’ fees and other expenses of an Indemnified Party shall be paid by the Company as they
are incurred upon receipt, in each case, of an undertaking by or on behalf of the Indemnified Party to repay such amounts if it is finally judicially determined that the Liabilities in question resulted solely from the gross negligence or willful
misconduct of such Indemnified Party. 
 The rights of an Indemnified Party to indemnification hereunder will be in addition to any other
rights and remedies any such person may have under any other agreement or instrument to which each Indemnified Party is or becomes a party or is or otherwise becomes a beneficiary or under any law or regulation. 
 SECTION 7. Accuracy of Information. The Company shall furnish or cause to be furnished to the Advisors such information as an Advisor
believes reasonably appropriate to rendering the Services and other services contemplated by this Agreement and to comply with the Securities and Exchange Commission or other legal requirements relating to the beneficial ownership by the Advisors or
their Affiliates of equity securities of the Company (all such information so furnished, the “Information”). The Company recognizes and confirms that the Advisors (a) will use and rely primarily on the Information and on
information available from generally recognized public sources in performing the Services and other services contemplated by this Agreement without having independently verified the same, (b) do not assume responsibility for the accuracy or
completeness of the Information and such other information and (c) are entitled to rely upon the Information without independent verification. 
 Section 8. Term. This Agreement will become effective as of the Effective Time and (except as otherwise provided herein) will continue until the “Termination Date,” which is the earliest of (i) the
tenth anniversary of the date hereof, (ii) such time as the Affiliated Investors beneficially own less than 5% of the total common equity of the Company in the aggregate, (iii) with respect to any Advisor, such Advisor’s Affiliated
Investors no longer hold at least 50% of the Units acquired by such Advisor’s Affiliated Investors on the date hereof and (iii) such earlier date as the Company and the Advisors may mutually agree upon in writing; provided, that
(x) the occurrence of the Termination Date will not affect the obligations of the Company to pay, or cause to be paid, any amounts accrued but not yet paid as of such date, (y) Section 5 hereof will remain in effect after the
Termination Date with respect to Out-of-Pocket Expenses that were incurred prior to or within a reasonable period of time after the Termination Date, but which have not been paid to the Advisors in accordance with Section 5 hereof, and
(z) the provisions of Sections 4(e), 4(g), 4(h), 6, 7, 9 and 10 hereof will survive after the Termination Date. The Advisory Fee will accrue and be payable with respect to the entire fiscal year of the Company in which the Termination Date

investment funds or portfolio companies), on the other hand, may engage in the same or similar activities or lines of business and have an interest in the same areas of corporate opportunities, in recognition of the benefits to be derived by the
Company hereunder, and in recognition of the difficulties which may confront any advisor who desires and endeavors fully to satisfy such advisor’s duties in determining the full scope of such duties in any particular situation, the provisions
of this Section 9(b) are set forth to regulate, define and guide the conduct of certain affairs of the Company as they may involve the Advisors. Except as the Advisors may otherwise agree in writing after the date hereof:

limitation, any business activities or lines of business that are the same as or similar to those pursued by, or competitive with, the Company and its subsidiaries); (B) to directly or indirectly do business with any client or customer of the
Company and its subsidiaries; (C) to take any other action that the Advisor believes in good faith is necessary to or appropriate to fulfill its obligations as described in the first sentence of this Section 9(b); and (D) not to
present potential transactions, matters or business opportunities to the Company or any of its subsidiaries, and to pursue, directly or indirectly, any such opportunity for themselves, and to direct any such opportunity to another person.

 (ii) The Advisors and their Affiliates shall have no duty (contractual or otherwise) to communicate or present any
corporate opportunities to the Company or any of its affiliates or to refrain from any actions specified in Section 9(b)(i) hereof, and the Company, on its own behalf and on behalf of its affiliates, hereby irrevocably waives any right to
require the Advisors or any of its Affiliates to act in a manner inconsistent with the provisions of this Section 9(b). 
 (iii) Neither the Advisors nor any of their Affiliates shall be liable to the Company or any of its affiliates for breach of any duty (contractual or otherwise) by reason of any activities or omissions of the types referred to in this
Section 9(b) or of any such person’s participation therein. 
  

 8 

 (c) Release. The Company hereby irrevocably and unconditionally releases and forever discharges
the Advisors and their Affiliates and their respective partners (both general and limited), members (both managing and otherwise), officers, directors, employees, agents and representatives from any and all liabilities, claims and causes of action
in connection with the Services or other services contemplated by this Agreement or the engagement of the Advisors pursuant to, and the performance by the Advisors of the Services or other services contemplated by, this Agreement that the Company
may have, or may claim to have, on or after the date hereof, except with respect to any act or omission that constitutes gross negligence or willful misconduct as determined by a final, non-appealable determination of a court of competent
jurisdiction. 
 (d) Limitation of Liability. In no event will the Advisors or any of their Affiliates be liable to the Company or any
of its affiliates for any indirect, special, incidental or consequential damages, including, without limitation, lost profits or savings, whether or not such damages are foreseeable, or for any third-party claims (whether based in contract, tort or
otherwise), relating to, in connection with or arising out of this Agreement, including, without limitation, the services to be provided by the Advisors or any of their Affiliates hereunder, or for any act or omission that does not constitute gross
negligence or willful misconduct as determined by a final, non-appealable determination of a court of competent jurisdiction or in excess of the fees actually received by the Advisors hereunder. 
 SECTION 10. Miscellaneous. 
 (a) No amendment or waiver of any provision of this Agreement, or consent to any departure by any party hereto from any such provision, will be effective unless it is in writing and signed by each of the parties hereto. Any amendment,
waiver or consent will be effective only in the specific instance and for the specific purpose for which given. The waiver by any party of any breach of this Agreement will not operate as or be construed to be a waiver by such party of any
subsequent breach.

 SECURITYHOLDERS AGREEMENT 
 This Securityholders Agreement (this “Agreement”) is entered into as of May 7, 2007 by and among PTS Holdings Corp., a Delaware
corporation (the “Company”), Blackstone Healthcare Partners V L.P., a Delaware limited partnership (“Blackstone”), BHP PTS Holdings, L.L.C. , a Delaware limited liability company (“Holdings”),
parties to this Agreement who are identified as Employees on the signature page hereto (each, an “Employee” and, collectively, the “Employees”), and each other holder of Securities who hereafter executes a separate
agreement to be bound by the terms hereof (Blackstone, the Employees and each other Person that is or may become a party to this Agreement as contemplated hereby are sometimes referred to herein collectively as the “Securityholders”
and individually as a “Securityholder”). Certain capitalized terms used herein are defined in Section 7.1. 
 The
parties hereto agree as follows: 
 ARTICLE I 
 REPRESENTATIONS AND WARRANTIES OF THE PARTIES 
 1.1 Representations and Warranties of the Company.
The Company hereby represents and warrants to the Securityholders that as of the date of this Agreement: 
 (a) it is a corporation, validly
existing and in good standing under the laws of the State of Delaware, it has full power and authority to execute, deliver and perform this Agreement and to consummate the transactions contemplated hereby, and the execution, delivery and performance
by it of this Agreement and the consummation of the transactions contemplated hereby have been duly authorized by all necessary corporate action; 
 (b) this Agreement has been duly and validly executed and delivered by the Company and constitutes a legal and binding obligation of the Company, enforceable against the Company in accordance with its terms; and 
 (c) the execution, delivery and performance by the Company of this Agreement and the consummation by the Company of the transactions contemplated hereby
will not, with or without the giving of notice or lapse of time, or both (i) violate any provision of law, statute, rule or regulation to which the Company is subject, (ii) violate any order, judgment or decree applicable to the Company,
or (iii) conflict with, or result in a breach or default under, any term or condition of the Company’s organizational documents or any agreement or instrument to which the Company is a party or by which it is bound. 

 1.2 Representations and Warranties of the Securityholders. Each Securityholder (as to himself or
itself only) represents and warrants to the Company and the other Securityholders that, as of the time such Securityholder becomes a party to this Agreement: 
 (a) this Agreement (or the separate joinder agreement executed by such Securityholder) has been duly and validly executed and delivered by such Securityholder, and this Agreement constitutes a legal and binding
obligation of such Securityholder, enforceable against such Securityholder in accordance with its terms; and 
 (b) the execution, delivery
and performance by such Securityholder of this Agreement (or any joinder to this Agreement) and the consummation by such Securityholder of the transactions contemplated hereby (and thereby) will not, with or without the giving of notice or lapse of
time, or both, (i) violate any provision of law, statute, rule or regulation to which such Securityholder is subject, (ii) violate any order, judgment or decree applicable to such Securityholder, or (iii) conflict with, or result in a
breach or default under, any term or condition of any agreement or other instrument to which such Securityholder is a party or by which such Securityholder is bound. 
 ARTICLE II 
 VOTING AGREEMENTS 
 2.1 Election of Directors. 
 (a) On or prior to the Lapse Date, each Person, other than the Company,
that is a party to this Agreement hereby agrees that such Person will vote, or cause to be voted, all voting securities of the Company over which such Person has the power to vote or direct the voting, and will take all other necessary or desirable
action within such Person’s control, and the Company will take all necessary and desirable actions within its control, to cause the authorized number of directors for each of the respective boards of directors of the Company and its
Subsidiaries to be established at up to seven directors, and to elect or cause to be elected to the respective boards of directors of the Company and each of its Subsidiaries and cause to be continued in office, such individuals as are designated
from time to time by Holdings. 
 (b) If at any time on or prior to the Lapse Date, Holdings shall notify the other parties to this Agreement
of their desire to remove, with or without cause, any individual from a Company or Subsidiary directorship, all such parties so notified will vote, or cause to be voted, all voting securities of the Company and the aforementioned Subsidiaries over
which they have the power to vote or direct the voting, and shall take all such other actions promptly as shall be necessary or desirable to cause the removal of such director. 
 (c) If at any time on or prior to the Lapse Date, any director ceases to serve on the board of directors of the Company or any of its Subsidiaries
(whether due to resignation, removal or otherwise), Holdings shall be entitled to designate a successor member/director to fill the vacancy created thereby. Each Person that is a party hereto agrees to vote, or cause to be voted, all voting
securities of the Company and the aforementioned Subsidiaries over which such Person has the power to vote or direct the voting, and shall take all such other actions as shall be necessary or desirable to cause the designated successor to be elected
to fill such vacancy. 
  

 2 

 (d) Nothing in this Agreement shall be construed to impair any rights that the unitholders or
stockholders of the Company or any Subsidiary of the Company may have to remove any director for cause under applicable law or the organizational documents of the Company or such Subsidiary, as the case may be. No such removal of an individual
designated pursuant to this Section 2.1 for cause shall affect any of Holdings’ rights to designate a different individual pursuant to this Section 2.1 to fill the position from which such individual was removed. 
 (e) The provisions of this Section 2.1 shall remain in effect following the first Public Offering. 
 2.2 Other Voting Matters. 
 (a) Each
party to this Agreement hereby agrees that such party will vote, or cause to be voted, all voting securities of the Company and its Subsidiaries over which such party has the power to vote or direct the voting, either in person or by proxy, whether
at a securityholders meeting, or by written consent, in the manner in which Holdings directs in connection with the approval of any amendment or amendments to the Company’s organizational documents, the merger, security exchange, combination or
consolidation of the Company with any other Person or Persons, the sale, lease or exchange of all or substantially all of the property and assets of the Company and its Subsidiaries on a consolidated basis, and the reorganization, recapitalization,
liquidation, dissolution or winding-up of the Company; provided, however, that this shall not apply with respect to any change in the Company’s organizational documents that would have a material adverse effect on the management of the Company.

 (b) In order to effectuate the provisions of Sections 2.1 and 2.2 hereof, each holder of Employee Securities hereby grants to John Lowry,
or if John Lowry shall cease to be the Chief Executive Officer of the Company, to his successor in such position with the Company, or if the Chief Executive Officer of the Company shall be unable to exercise this proxy due to illness or absence or
if the position of Chief Executive Officer of the Company shall be vacant, to the General Counsel of the Company, a proxy to vote at any annual or special meeting of Securityholders, or to take any action by written consent in lieu of such meeting
with respect to, or to otherwise take action in respect of, all of the Securities owned or held of record by such holder in connection with the matters set forth in Sections 2.1 and 2.2 hereof in accordance with the provisions of Sections 2.1 and
2.2 hereof. Each of the proxies granted hereby is irrevocable and is coupled with an interest. To effectuate the provisions of this Section 2.2(b), the Secretary of each of the Company and each of the aforementioned Subsidiaries of the Company,
or if there be no Secretary such other officer or employee of the Company or such Subsidiaries as the board of directors of the Company or such Subsidiaries may appoint to fulfill the duties of the Secretary, shall not record any vote or consent or
other action contrary to the terms of this Section 2.2(b). 
  

 3 

 ARTICLE III 
 TRANSFERS OF SECURITIES 
 3.1 Restrictions on Transfer of Employee Securities. Prior to the earliest
of (i) a Qualified Public Offering, (ii) the occurrence of a Change of Control and (ii) the fifth anniversary of the date hereof (the “Lapse Date”), no holder of Employee Securities may Transfer any Employee
Securities except in an Exempt Employee Transfer. 
 3.2 Right of First Refusal. 
 (a) If, at any time on or after the Lapse Date and prior to a Qualified Public Offering, any holder of Employee Securities (for purposes of this
Section 3.2(a), a “Selling Employee Holder”) proposes to sell any or all of his Employee Securities (other than in an Exempt Employee Transfer) to a third party (a “Proposed Sale”), such Selling Employee Holder
shall first notify the Company in writing. Such Selling Employee Holder’s notice to the Company (the “Proposed Sale Notice”) shall (i) state such Selling Employee Holder’s intention to sell Employee Securities to one
or more persons, the amount of Employee Securities to be sold, the purchase price therefor, and the other material terms of the Proposed Sale and (ii) contain an irrevocable offer to sell such Employee Securities to the Company (in the manner
set forth below) at a purchase price equal to the price contained in, and on the same terms and conditions of, the Proposed Sale. 
 (b) At
any time within fifteen (15) days after the date of the receipt by the Company of the Proposed Sale Notice, the Company shall have the right and option to purchase, or to arrange for a third party to purchase, all of the Employee Securities
covered by the Proposed Sale Notice at the same price and on the same terms and conditions of the Proposed Sale (or, if the Proposed Sale includes any consideration other than cash, then, at the sole option of the Company, at the equivalent all cash
price, determined in good faith by the board directors of the Company taking into account the value of the property), by delivering a certified bank check or checks in the appropriate amount (or by wire transfer of immediately available funds, if
the Selling Employee Holder provides to the Company wire transfer instructions) (and any such non-cash consideration to be paid) to the Selling Employee Holder at the principal office of the Company against delivery of certificates or other
instruments representing the Employee Securities so purchased, appropriately endorsed by the Selling Employee Holder. If at the end of the 15-day period, the Company or such third party has not tendered the purchase price for such Employee
Securities in the manner set forth above, the Selling Employee Holder may, during the succeeding 60-day period, sell not less than all of the Employee Securities covered by the Proposed Sale to a third party on terms no less favorable to the Selling
Employee Holder than those contained in the Proposed Sale Notice. Promptly after such sale, the Selling Employee Holder shall notify the Company of the consummation thereof and shall furnish such evidence of the completion and time of completion of
such sale and of the terms thereof as may reasonably be requested by the Company. If, at the end of sixty (60) days following the expiration of the 15-day period during which the Company is entitled hereunder to purchase the Employee
Securities, the 

  

 4 

 
Selling Employee Holder has not completed the sale of such Employee Securities as aforesaid, all of the restrictions on sale, transfer or assignment
contained in this Agreement shall again be in effect with respect to such Employee Securities. 
 3.3 Restrictions on Transfers of
Blackstone Securities. 
 (a) Tag-Along Rights. Subject to the next paragraph, prior to making any Transfer of Blackstone
Securities (other than a Transfer described in Section 3.3(b)) held by Blackstone on the Closing Date, any holder of Blackstone Securities proposing to make such a Transfer (for purposes of this Section 3.3, a “Selling Blackstone
Holder”) shall give at least twenty one (21) days’ prior written notice to each holder of Employee Securities (for purposes of this Section 3.3, each an “Other Holder”) and the Company, which notice (for
purposes of this Section 3.3, the “Sale Notice”) shall identify the type and amount of Blackstone Securities to be sold (for purposes of this Section 3.3, the “Offered Securities”), describe the terms and
conditions of such proposed Transfer, and identify each prospective transferee. Any of the Other Holders may, within fourteen (14) days of the receipt of the Sale Notice, give written notice (each, a “Tag-Along Notice”) to the
Selling Blackstone Holder that such Other Holder wishes to participate in such proposed Transfer upon the terms and conditions set forth in the Sale Notice, which Tag-Along Notice shall specify the Employee Securities such Other Holder desires to
include in such proposed Transfer; provided, however, that (1) each Other Holder shall be required, as a condition to being permitted to sell Employee Securities pursuant to this Section 3.3(a) in connection with a Transfer of Offered
Securities, to elect to sell Employee Securities of the same type and class and in the same relative proportions as the Securities which comprise the Offered Securities, (2) Employee Securities that are subject to vesting shall not be entitled
to be sold pursuant to this Section 3.3(a) unless such Employee Security has fully vested; and (3) to exercise its tag-along rights hereunder, each Other Holder must agree to make to the transferee the same representations, warranties,
covenants, indemnities and agreements as the Selling Blackstone Holder agrees to make in connection with the Transfer of the Offered Securities (except that in the case of representations and warranties pertaining specifically to, or covenants made
specifically by, the Selling Blackstone Holder, the Other Holders shall make comparable representations and warranties pertaining specifically to (and, as applicable, covenants by) themselves), and must agree to bear his or its ratable share (which
may be joint and several but shall be based on, and limited to, the value of Securities that are Transferred by each such Securityholder) of all liabilities to the transferees arising out of representations, warranties, covenants and indemnities
(other than those representations, warranties, covenants and indemnities that pertain specifically to a given Securityholder, who shall bear all of the liability related thereto) or other agreements made in connection with the Transfer. Each
Securityholder will bear (x) its or his own costs of any sale of Securities pursuant to this Section 3.3(a) and (y) its or his pro-rata share (based upon the relative amount of proceeds received for the Securities sold) of the costs
of any sale of Securities pursuant to this Section 3.3(a) (excluding all amounts paid to any Securityholder or his or its Affiliates as a transaction fee, broker’s fee, finder’s fee, advisory fee, success fee, or other similar fee or
charge related to the consummation of such sale) to the extent such costs are incurred for the benefit of all Securityholders and are not otherwise paid by the transferee. 
  

 5 

 If none of the Other Holders gives the Selling Blackstone Holder a timely Tag-Along Notice with respect
to the Transfer proposed in the Sale Notice, then (notwithstanding the first sentence of Section 3.3(a)) the Selling Blackstone Holder may Transfer such Offered Securities on the terms and conditions set forth, and to or among any of the
transferees identified (or Affiliates of transferees identified), in the Sale Notice at any time within ninety (90) days after expiration of the fourteen-day period for giving Tag-Along Notices with respect to such Transfer. Any such Offered
Securities not Transferred by the Selling Blackstone Holder during such ninety-day period will again be subject to the provisions of this Section 3.3(a) upon subsequent Transfer. If one or more Other Holders give the Selling Blackstone Holder a
timely Tag-Along Notice, then the Selling Blackstone Holder shall use its reasonable efforts to obtain the agreement of the prospective transferee(s) to the participation of the Other Holders in any contemplated Transfer, on the same terms and
conditions as are applicable to the Offered Securities, and no Selling Blackstone Holder shall transfer any of its units or shares, as the case may be, to any prospective transferee if such prospective transferee(s) declines to allow the
participation of the Other Holders. If the prospective transferee(s) is unwilling or unable to acquire all of the Offered Securities and all of the Employee Securities specified in a timely Tag-Along Notice upon such terms, then the Selling
Blackstone Holder may elect either to cancel such proposed Transfer or to allocate the maximum number of each class of Securities that the prospective transferees are willing to purchase (the “Allocable Shares”) among the Selling
Blackstone Holder and the Other Holders giving timely Tag-Along Notices as follows (it being understood that the prospective transferees shall be required to purchase Securities of the same class on the same terms and conditions taking into account
the provisions of clause (1) of Section 3.3(a), and to consummate such Transfer on those terms and conditions): 
 (i) each participating Securityholder (including the Selling Blackstone Holder) shall be entitled to sell a number of shares or units of each class of Securities (taking into account the provisions of clause (1) of Section 3.3(a))
(not to exceed, for any Other Holder, the number of shares or units of such class of Securities identified in such Other Holder’s Tag-Along Notice) equal to the product of (A) the number of Allocable Shares of such class of Securities and
(B) a fraction, the numerator of which is such Securityholder’s Ownership Percentage of such class of Securities and the denominator of which is the aggregate Ownership Percentage for all participating Securityholders of such class of
Securities; provided, however, that if a Securityholder was unable to sell Securities in one or more prior Transfers effected pursuant to this Section 3.3(a) because of clause (2) of Section 3.3(a) and, as a result, the
aggregate percentage of Securities sold by such Securityholder in Transfers effected pursuant to this Section 3.3(a) is less than the aggregate percentage of Securities sold by Blackstone in such Transfers, then additional Allocable Shares
shall be allocated to such Securityholder (not to exceed the number of Securities identified in such Securityholder’s Tag-Along Notice) in priority over other Securityholders until, after giving effect to the Transfer proposed to be effected,
the aggregate percentage of Securities sold by Blackstone and such Securityholder are equal; and 
  

 6 

 (ii) if after allocating the Allocable Shares of any class of Securities to such
Securityholders in accordance with clause (i) above, there are any Allocable Shares of such class that remain unallocated, then they shall be allocated (in one or more successive allocations on the basis of the allocation method specified in
clause (i) above) among the Selling Blackstone Holder and each such Other Holder that has elected in its Tag-Along Notice to sell a greater number of shares or units of such class of Securities than previously has been allocated to it pursuant
to clause (i) and this clause (ii) (all of whom (but no others) shall, for purposes of clause (i) above, be deemed to be the participating Securityholders) until all such Allocable Shares have been allocated in accordance with this
clause (ii). 
 (b) Excluded Transfers. The rights and restrictions contained in Section 3.3(a) shall not apply with respect to
any of the following Transfers of Securities: 
 (i) any Transfer of Blackstone Securities to any Person or group of Persons
on or prior to the six month anniversary of the Closing Date in connection with the syndication of such Blackstone Securities; 
 (ii) any Transfer of Blackstone Securities in a Public Sale (subject to the registration rights of holders of Employee Securities in Article V); 
 (iii) any Transfer of Blackstone Securities to and among the members, partners or Affiliates of Blackstone and the members, partners, securityholders and employees of such partners (subject to compliance with Sections
3.4 and 3.5 hereof); 
 (iv) any Transfer of Blackstone Securities in accordance with Section 4.1; 
 (v) any Transfer of Blackstone Securities incidental to the exercise, conversion or exchange of such securities in accordance with their
terms or any reclassification or combination of shares (including any reverse stock split) or any recapitalization, reorganization or reclassification of, or any merger or consolidation involving, the Company; and 
 (vi) any Transfer of Blackstone Securities to employees or directors of, or consultants to, any of the Company and its Subsidiaries.

 (c) Excluded Securities. No Securities that have been transferred by the Selling Blackstone Holder or an Other Holder in a Transfer
pursuant to the provisions of Section 3.3(a) (“Excluded Securities”) shall be subject again to the restrictions set forth in Section 3.3(a), nor shall any Securityholder holding Excluded Securities be entitled to exercise
any rights as an Other Holder under Section 3.3(a) with respect to such Excluded Securities, and no Excluded Securities held by a Selling Blackstone Holder or any Other Holder shall be counted in determining the respective participation rights
of such holders in a Transfer subject to Section 3.3(a). 
  

 7 

 (d) The provisions of this Section 3.3 shall remain in effect following the first Public Offering.

 3.4 Securities Act Compliance. No Securities may be transferred by a holder of Employee Securities (other than pursuant to an
effective registration statement under the Securities Act) unless such Securityholder first delivers to the Company an opinion of counsel, which opinion and counsel shall be reasonably satisfactory to the Company, to the effect that such Transfer is
not required to be registered under the Securities Act. 
 3.5 Certain Transferees Bound by Agreement. Subject to compliance with the
other provisions of this Article III, any Securityholder may Transfer any Securities held by such Securityholder in accordance with applicable law; provided, however, that if the Transfer is not made pursuant to a Public Sale or a transaction the
consummation of which will cause the termination of this Agreement pursuant to Article VI, then the transferor of such Security shall first deliver to the Company a written agreement of the proposed transferee (excluding a transferee that is a
Limited Partner) to become a Securityholder and to be bound by the terms of this Agreement (unless such proposed transferee is already a Securityholder). All Employee Securities will continue to be Employee Securities in the hands of any transferee
(other than the Company, Blackstone or any transferee in a Public Sale); provided that Employee Securities Transferred pursuant to an exercise of tag-along rights as an Other Holder under Section 3.3(a) shall not be subject to the provisions of
Section 3.1 in the hands of the transferee or any subsequent transferee. All Blackstone Securities will continue to be Blackstone Securities in the hands of any transferee (other than the Company, the Employees or a transferee in a Public
Sale). 
 3.6 Transfers in Violation of Agreement. Any Transfer or attempted Transfer of any Securities in violation of any provision
of this Agreement shall be void, and the Company shall not record such Transfer on its books or treat any purported transferee of such Securities as the owner of such Securities for any purpose. 
 ARTICLE IV 
 DRAG-ALONG RIGHTS ON APPROVED SALE

 4.1 Drag-Along Rights. 
 (a) Subject to the next paragraph, if Blackstone or Holdings elects to consummate, or to cause the Company to consummate, a transaction constituting a Change of Control, Blackstone or Holdings, as applicable, shall notify the Company and
the other Securityholders in writing of that election, the other Securityholders will consent to and raise no objections to the proposed transaction, and the Securityholders and the Company will take all other actions reasonably necessary or
desirable to cause the consummation of such transaction on the terms proposed by Blackstone or Holdings (a “Drag Along Sale”). Without limiting the foregoing, (i) if the proposed Drag Along Sale is structured as a sale of
assets or a merger or consolidation, or otherwise requires 

  

 8 

 
Securityholders approval, the Securityholders and the Company will vote or cause to be voted all Securities that they hold or with respect to which such
Securityholder has the power to direct the voting and which are entitled to vote on such transaction in favor of such transaction and will waive any appraisal rights which they may have in connection therewith, and (ii) if the proposed Drag
Along Sale is structured as or involves a sale or redemption of Securities, the Securityholders will agree to sell their pro-rata share of the Securities being sold in such Drag Along Sale on the terms and conditions approved by Blackstone or
Holdings, and the Securityholders will execute any merger, asset purchase, security purchase, recapitalization or other sale agreement approved by Blackstone in connection with such Change of Control. 
 (b) The obligations of the Securityholders with respect to the Drag Along Sale are subject to the satisfaction of the following conditions: (i) upon
the consummation of the Drag Along Sale, all of the holders of a particular class or series of Securities (if any consideration is to be received by any of them) shall receive the same form and amount of consideration per share, unit or amount of
Securities, or if any holders of a particular class or series of Securities are given an option as to the form and amount of consideration to be received, all holders of such class or series will be given the same option and (ii) if
consideration is to be received by holders of Securities, all holders of then currently exercisable rights to acquire a particular class or series of Securities will be given an opportunity to either (A) exercise such rights prior to the
consummation of the Drag Along Sale and participate in such sale as holders of such Securities or (B) upon the consummation of the Drag Along Sale, receive in exchange for such rights consideration equal to the amount determined by multiplying
(1) the same amount of consideration per share, unit or amount of Securities received by the holders of such type and class of Securities in connection with the Drag Along Sale less the exercise price per share, unit or amount of such rights to
acquire such Securities by (2) the number of shares, units or aggregate amount of Securities represented by such rights. 
 (c) Each
Securityholder will bear its or his pro-rata share (based upon the relative amount of proceeds received for the Securities sold) of the reasonable costs of any sale of Securities pursuant to a Drag Along Sale to the extent such costs are incurred
for the benefit of all Securityholders and are not otherwise paid by the Company or the acquiring party. Costs incurred by or on behalf of a Securityholder for its or his sole benefit will not be considered costs of the transaction hereunder. In the
event that any transaction that Blackstone elects to consummate or cause to be consummated pursuant to this Section 4.1 is not consummated for any reason, the Company will reimburse Blackstone for all actual and reasonable expenses paid or
incurred by Blackstone in connection therewith. No Securityholder shall be required to make any representation, warranty, covenant or indemnity that pertains specifically to any other Securityholder, nor shall any Securityholder be required to enter
into any non-competition agreement in connection with such Change of Control transaction. 
 (d) Notwithstanding any provision in this
Agreement to the contrary, Blackstone and its Affiliates shall be entitled to be paid customary and reasonable fees by Holdings, the Company or any Subsidiary for any investment banking services provided by it in connection with a Change of Control.

  

 9 

 (e) The provisions of this Section 4.1 shall remain in effect following the first Public Offering.

 ARTICLE V 
 PIGGYBACK RIGHTS

 5.1 Piggyback Rights. The parties hereto agree that, with respect to the Employee Securities, the Employees shall have all of the
piggyback rights of a Securityholder as set forth under Article IV of the Holdings Securityholders Agreement. 
 ARTICLE VI 
 AMENDMENT AND TERMINATION 
 6.1 Amendment
and Waiver. Except as otherwise provided herein, no modification, amendment or waiver of any provision of this Agreement shall be effective against the Company or the Securityholders unless such modification, amendment or waiver is approved in
writing by each of the Company and Holdings; provided that no such modification, amendment or waiver may materially and adversely affect Section 2.2(a) of this Agreement, Employee Securities or the rights or obligations hereunder of
holders of Employee Securities unless approved in writing by the Employee Majority Holders. The failure of any party to enforce any of the provisions of this Agreement shall in no way be construed as a waiver of such provisions and shall not affect
the right of such party thereafter to enforce each and every provision of this Agreement in accordance with its terms. 
 6.2 Termination
of Agreement. This Agreement will terminate in respect of all Securityholders (a) with the written consent of the Company, Holdings and the Employee Majority Holders, (b) upon the dissolution, liquidation or winding-up of the Company
or (c) upon the consummation of a Change of Control (except with respect to the registration rights under Article V, which shall survive). The termination of this Agreement will not affect any indemnification and contribution obligations under
Article V, which shall survive. 
 6.3 Termination as to a Party. Any Person who ceases to hold any Securities shall cease to be a
Securityholder and shall have no further rights or obligations under this Agreement (except with respect to any indemnification and contribution obligations under Article V).
