Termination Date, to sell to the Company, and the Company shall be required to purchase (subject to the provisions of Section 5 hereof), on one occasion
from Executive, all (or any portion) of Executive’s Class A Units and Vested Units at a price per Unit equal to Fair Market Value (measured as of the purchase date); provided that the exercise of such right may be delayed by the Company to
the extent any such delay is necessary to avoid the application of adverse accounting treatment to the Company. 
 (b) If Executive or
Executive’s Family Group, as applicable, desires to exercise its option to require the Company to repurchase Class A Units and Vested Units pursuant to Section 4.1(a), Executive or Executive’s Family Group, as applicable, shall
send written notice to the Company setting forth Executive’s or Executive’s Family Group, as applicable, intention to sell all of his or their Class A Units and Vested Units, as applicable, pursuant to Section 4.1(a) (the

the Class A Units purchased on the Closing Date) and Vested Units at a price per Unit equal to the applicable purchase price determined as follows: 
 (i) Termination for Cause. If Executive’s service with the Company and its Subsidiaries is terminated by the Company or any of its Subsidiaries for Cause, the purchase price per Unit will be the lesser of
(A) Fair Market Value (measured as of the purchase date) and (B) Cost; or 
 (ii) Termination of Service Other
than for Cause. If Executive’s service with the Company and its Subsidiaries is terminated for any reason other than by the Company or any of its Subsidiaries for Cause, the purchase price per Unit will be Fair Market Value (measured as of
the purchase date). 
 (b) If the Company desires to exercise its option to purchase such Units and Vested Units pursuant to
Section 4.2(a), the Company shall, not later than 181 days after the Termination Date, send written notice to Executive of its intention to purchase such Units, specifying the number of Units to be purchased (the “Call
Notice”). Subject to the provisions of Section 5, the closing of the purchase shall take place at the principal office of the Company on a date specified by the Company no later than the 30th day after the giving of the Call Notice.

 (c) Notwithstanding the foregoing, if the Company elects not to exercise its option to purchase Units pursuant to Section 4.2 and
Executive’s employment with the Company and its Subsidiaries terminated for any of the reasons set forth in clauses (a)(i) or (a)(ii) above prior to the Lapse Date, Blackstone may elect to purchase such Units on the same terms and 

  

 7

expiration of the Company’s 181 day call window following the Termination Date.

 5.1 Deferral of Purchases. (a) Notwithstanding anything to the contrary contained herein, the Company shall not be obligated to purchase any Units at any time pursuant to Section 4, regardless of

promulgated or entered by any federal, state, local or foreign court or governmental authority applicable to the Company or any of its Subsidiaries or any of its or their property or (B) after giving effect thereto, a Financing Default,
(ii) if immediately prior to such purchase there exists a Financing Default which prohibits such purchase or (iii) to the extent there is a lack of available cash on hand of the Company and no cash is available to the Company. The Company

effect as of the date of the exercise of the call right or at the applicable Applicable Federal Rate at such time, if greater; provided, however, that the Company shall fully satisfy its obligation under the note sooner if the purchase price is no
longer restricted under Section 5.1(a), with such amount paid to Executive or Executive’s Family Group, as applicable, within fifteen (15) days after the date the prohibition is lifted or (y) if purchase by delivery of a note as
described in clause (x) is not permitted due to the terms of any outstanding Company indebtedness, or otherwise, then, for the applicable purchase price (measured as of the actual purchase date) on or prior to the fifteenth (15th) day after such date or dates that the purchase of such Units are no longer prohibited under Section 5.1(a) and the Company shall give Executive
five (5) days’ prior notice of any such purchase. Notwithstanding the anything herein to the contrary, prior to the payment of the purchase price under this Section 5.1, Executive or Executive’s Family Group may withdraw the
Units subject to the put option described in Section 4.1. 
 5.3 Payment for Units. If at any time the Company elects to

 (a) the
offer and sale of Shares have not been registered under the Securities Act;

continue to bear the economic risk of the investment in the Shares unless the offer and sale of the Shares are subsequently registered under the Securities Act and all applicable state securities laws or an exemption from such registration is
available; 
 (c) there is no established market for the Shares and it is not anticipated that there will be any public market for the Shares
in the foreseeable future; 
 (d) a restrictive legend in the form set forth below and the legends set forth in Section 7.2 of the
Securityholders Agreement shall be placed on the certificates representing the Common Stock: 
 “THE SECURITIES
REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO CERTAIN REPURCHASE OPTIONS AND OTHER PROVISIONS SET FORTH IN A MANAGEMENT EQUITY SUBSCRIPTION AGREEMENT WITH THE ISSUER DATED AS OF ____ __, ____, AS AMENDED AND MODIFIED FROM TIME TO TIME, A COPY OF
WHICH MAY BE OBTAINED BY THE HOLDER HEREOF AT THE ISSUER’S PRINCIPAL PLACE OF BUSINESS WITHOUT CHARGE”; and

represents and warrants that: 
 (a) Executive’s financial situation is such that Executive can afford to bear the economic risk of

providing for Executive’s current needs and personal contingencies, and can afford to suffer a complete loss of Executive’s investment in the
Shares;

the merits and risks of the investment in the Shares;

involves a high degree of risk of loss of Executive’s investment therein, there are substantial restrictions on the transferability of the Shares and, on the Closing Date and for an indefinite period following the Closing, there will be no

 (d) the terms of this Agreement provide that, with respect to the Shares received upon exercise of the Option only, if Executive ceases to be an employee of the Company or its Subsidiaries, the Company and its

Executive’s representatives concerning the Shares or the Company or their prospects or other matters;

	4.	Certain Sales Upon Termination of Employment 

 4.1 Put
Option 
 (a) If Executive’s employment with the Company and its Subsidiaries terminates due to the Disability or death of the
Executive prior to the Lapse Date, the Executive and the Executive’s Family Group shall have the right, subject to the provisions of Section 5 hereof, for one year following the later of (x) the Termination Date or (y) the date
of receipt of the Shares following exercise of the Option, to sell to the Company, and the Company shall be required to purchase (subject to the provisions of Section 5 hereof), on one occasion from Executive, all (or any portion) of
Executive’s Shares at a price per Share equal to Fair Market Value (measured as of the purchase date); provided that the exercise of such right may be delayed by the Company to the extent any such delay is necessary to avoid the application of
adverse accounting treatment to the Company. 
 (b) If Executive or Executive’s Family Group, as applicable, desires to exercise its
option to require the Company to repurchase Shares pursuant to Section 4.1(a), Executive or Executive’s Family Group, as applicable, shall send written notice to the Company setting forth Executive’s or Executive’s Family Group,
as applicable, intention to sell all of his or their Shares, as applicable, pursuant to Section 4.1(a) (the “Put Notice”). Subject to the provisions of Section 5, the closing of the purchase shall take place at the
principal office of the Company on a date specified by the Company no later than the 60th day after the giving of such notice. 
 4.2 Call
Option. 
 (a) If Executive’s employment with the Company and its Subsidiaries terminates for any of the reasons set forth in clauses
(i) or (ii) below prior to the Lapse Date, the Company shall have the right and option, but not the obligation, to purchase any or all of Executive’s Shares issuable or issued upon exercise of the Option for a period of 181 days (or
such longer period as is necessary in order to avoid the application of adverse accounting treatment to the Company) following the later of (x) the Termination Date or (y) the date of receipt of the Shares following exercise of the Option,
in each case, at a price per Share equal to the applicable purchase price determined as follows: 
 (i) Termination for
Cause. If Executive’s employment with the Company and its Subsidiaries is terminated by the Company or any of its Subsidiaries for Cause, the purchase price per Share will be the lesser of (A) Fair Market Value (measured as of the
purchase date) and (B) Cost; or 
 (ii) Termination of Employment Other than for Cause. If Executive’s
employment with the Company and its Subsidiaries is terminated for any reason other than by the Company or any of its Subsidiaries for Cause, the purchase price per Share will be Fair Market Value (measured as of the purchase date). 
 (b) If the Company desires to exercise its option to purchase such Shares pursuant to Section 4.2(a), the Company shall, not later than 181 days
following the later of (x) the Termination Date or (y) the date of receipt of the Shares following exercise of the Option, send written notice to Executive of its intention to purchase Shares, specifying the number of Shares to be
purchased (the “Call Notice”). Subject to the provisions of Section 5, the closing of the purchase shall take place at the principal office of the Company on a date specified by the Company no later than the 30th day after the
giving of the later of the Call Notice. 
  

 6 

 (c) Notwithstanding the foregoing, if the Company elects not to exercise its option to purchase Shares
pursuant to this Section 4 and Executive’s employment with the Company and its Subsidiaries terminated for any of the reasons set forth in clauses (a)(i) or (a)(ii) above prior to the Lapse Date, Blackstone may elect to purchase such
Shares on the same terms and conditions set forth in this Section 4.2 by providing written notice to Executive of its intention to purchase Shares within 30 days after the expiration of the Company’s 181 day call window following the later
of (x) the Termination Date or (y) the date of receipt of the Shares following exercise of the Option. 
  

	5.	Certain Limitations on the Company’s Obligations to Purchase Shares. 

 5.1 Deferral of Purchases. (a) Notwithstanding anything to the contrary contained herein, the Company shall not be obligated to purchase any Shares at any time pursuant to Section 4, regardless of
whether it has delivered a Call Notice or received a Put Notice, (i) to the extent that the purchase of such Shares would result in (A) a violation of any law, statute, rule, regulation, policy, order, writ, injunction, decree or judgment
promulgated or entered by any federal, state, local or foreign court or governmental authority applicable to the Company or any of its Subsidiaries or any of its or their property or (B) after giving effect thereto, a Financing Default,
(ii) if immediately prior to such purchase there exists a Financing Default which prohibits such purchase, or (iii) to the extent that there is a lack of available cash on hand of the Company and no cash is available to the Company. The
Company shall, within fifteen (15) days of learning of any such fact, so notify Executive that it is not obligated to purchase hereunder. 
 (b) Notwithstanding anything to the contrary contained in Section 4, provided the Lapse Date
has not occurred, any Shares which Executive or Executive’s Family Group, as applicable, has elected to sell or the Company has elected to purchase, but which in accordance with Section 5.1(a) is not purchased at the applicable time
provided in Section 4, shall be purchased by the Company (x) by delivery of a note for the applicable purchase price payable in equal installments of up to three (3) years, bearing interest at the prime lending rate in effect as of
the date of the exercise of the call right or at the applicable Applicable Federal Rate at such time, if greater; provided, however, that the Company shall fully satisfy its obligation under the note sooner if the purchase price is no longer
restricted under Section 5.1(a), with such amount paid to Executive or Executive’s Family Group, as applicable, within fifteen (15) days after the date the prohibition is lifted or (y) if purchase by delivery of a note as
described in clause (x) is not permitted due to the terms of any outstanding Company indebtedness, or otherwise, then, for the applicable purchase price (measured as of the actual purchase date) on or prior to the fifteenth (15th) day after such date or dates that the purchase of such Shares are no longer prohibited under Section 5.1(a) and the Company shall give Executive
five (5) days’ prior notice of any such purchase. Notwithstanding the anything herein to the contrary, prior to the payment of the purchase price under this Section 5.1, Executive or Executive’s Family Group may withdraw the
Shares subject to the put option described in Section 4.1. 
 5.2 Payment for Shares. If at any time the Company elects to
purchase any Shares pursuant to Section 4, unless otherwise provided for herein, the Company shall pay the purchase price for the Shares it purchases (i) first, by the cancellation of any indebtedness owing from Executive to the Company or
any of its Subsidiaries and (ii) then, by the Company’s delivery of a check or wire transfer of immediately available funds for the remainder of the purchase price, 
  

 7 

 
if any, against delivery of the certificates or other instruments representing the Shares so purchased, duly endorsed. 
  

	6.	Noncompetition; Nonsolicitation; Confidentiality.

 (i) Executive will not, whether on Executive’s own behalf or on behalf of or in conjunction with any person, firm, partnership, joint venture,
association, corporation or other business organization, entity or enterprise whatsoever (“Person”), directly or indirectly, solicit or assist in soliciting in competition with the Company or any of its Subsidiaries, the business of
any client or prospective client:

business which the Company or any of its Subsidiaries have plans to engage in as of the date of Executive’s termination of employment) in any geographical area where the Company or any of its Subsidiaries conduct business (a
“Competitive Business”); 

  

	 	(2)	enter the employ of, or render any services to, any Person (or any division or controlled or controlling Affiliate of any Person) who or which engages in a Competitive Business;

  

 8 

	 	(3)	acquire a financial interest in, or otherwise become actively involved with, any Competitive Business, directly or indirectly, as an individual, partner, shareholder, officer,

and customers, clients, suppliers, or investors of the Company or any of its Subsidiaries. 

 Notwithstanding
anything to the contrary in this Agreement, Executive may, directly or indirectly own, solely as an investment, securities of any entity engaged in the business of the Company or any of its Subsidiaries which are publicly traded on a national or

reasonable, if a final judicial determination is made by a court of competent jurisdiction that the time or territory or any other restriction contained in this Agreement is an unenforceable restriction against Executive, the provisions of this
Agreement shall not be rendered void but shall be deemed amended to apply as to such maximum time and territory and to such maximum extent as such court may judicially determine or indicate to be enforceable. Alternatively, if any court of competent
jurisdiction finds that any restriction contained in this Agreement is unenforceable, and such restriction cannot be amended so as to make it enforceable, such finding shall not affect the enforceability of any of the other restrictions contained
herein

treatment.

its Affiliates); provided, that Executive may disclose to any prospective future employer the provisions of Section 6.1 of this Agreement provided they agree to maintain the confidentiality of such terms.

Company, within ten (10) business days following the first date on which Executive first breaches such provisions, an amount equal to the excess, if any, of (A) the aggregate proceeds Executive received upon the sale or other disposition
of, or distributions in respect of, Executive’s Shares over (B) the aggregate Cost of such Shares. 
 6.4 Notwithstanding anything
herein to the contrary, in the event of any conflict between the terms of Sections 6.1 and 6.2 and the terms of any employment, non-competition or confidentiality agreement between Executive and the Company and its Subsidiaries, the terms of such
employment, non-competition or confidentiality agreement shall govern.

undertaking to be bound by the terms of this Agreement and (b) acknowledging that the Shares transferred to such Person will continue to be Shares for purposes of this Agreement in the hands of such Person. Any transfer or attempted transfer of

purpose.

 11 

 7.5 Binding Effect. The provisions of this Agreement shall be binding upon and accrue to the
benefit of the parties hereto and their respective heirs, legal representatives, successors and assigns; provided, however, that no transferee shall derive any rights under this Agreement unless and until such transferee has executed and delivered
