Shares subject to an Option until the Participant has given written notice of exercise of the Option, paid in full for such Shares and, if applicable, has satisfied any other conditions imposed by the Committee pursuant to the Plan, provided, in
each case, that the Participant tenders cash or its equivalent to pay any applicable withholding or other applicable taxes (unless otherwise permitted by the Committee).

articles of association (as may be amended from time to time), and the Committee may cause a legend or legends to be put on any such certificates or entries in the register of members of the Company to make appropriate reference to such
restrictions. 
 9.    Transferability. An Option may not be assigned, alienated, pledged, attached, sold or

unenforceable against the Company or any Affiliate; provided that the designation of a beneficiary shall not constitute an assignment, alienation, pledge, attachment, sale, transfer or encumbrance. No such permitted transfer of an Option to heirs or
legatees of the Participant shall be effective to bind the Company unless the Committee shall have been furnished with written notice thereof and a copy of such evidence as the Committee may deem necessary to establish the validity of the transfer
and the acceptance by the transferee or transferees of the terms and conditions thereof. During the Participant’s lifetime, an Option is exercisable only by the Participant. 

10.    Withholding. No Shares shall be delivered pursuant to any exercise of the Vested Portion of an Option until
payment in full of the Exercise Price therefor is received by the Company and the Participant has paid to the Company an amount equal to any Federal, state, local and non-U.S. income and employment taxes and
other applicable taxes required to be withheld in accordance with the terms of this Agreement and the Plan. The Participant shall be required to pay to the Company or any Affiliate and the Company or its Affiliates shall have the right and are
authorized to withhold any applicable withholding or other applicable taxes in respect of an Option, its exercise, or any payment or transfer under or with respect to an Option and to take such other action as may be necessary in the opinion of the
Committee to satisfy all obligations for the payment of such withholding or other applicable taxes.

3.    Vesting of the Options; Expiration of Unvested Options. 

(a)    Vesting of the Tier I Option. 

 (i) In General. Subject to the Participant’s continued Employment
through each applicable vesting date, the Tier I Option shall vest and become exercisable with respect to twenty percent (20%) of the Shares subject to such Tier I Option on each of the first five anniversaries of the Date of Grant. 

(ii) Change in Control. Notwithstanding the foregoing, in the event of a Change in Control during the
Participant’s continued Employment, the Tier I Option shall, to the extent not then vested or previously forfeited or cancelled, become fully vested and exercisable. 

(b)    Vesting of the Tier II Option and the Tier IV Option. Subject to the Participant’s continued Employment
through the applicable vesting date, each of the Tier II Option and the Tier IV Option shall vest if, on or after a Liquidity Event and on or prior to July 3, 2022, Sponsor shall have received net cash proceeds generated together with all
Sponsor Outflows received, in each case, in respect of all Shares sold by it or in connection with an Asset Sale, as applicable, that results in either (i) a return of at least 2.0 times the amount of the Sponsor’s cumulative invested
capital in respect of such sold Shares or (ii) an annual internal rate of return of at least fifteen percent (15%) on the Sponsor’s cumulative invested capital in respect of such sold Shares. For the avoidance of doubt, following
July 3, 2022, each of the Tier II Option and the Tier IV Option, to the extent not then vested, shall not be eligible to become vested and shall automatically be immediately canceled without consideration. In connection with any
Liquidity Event in which the Tier II Option and the Tier IV Option are expected to become vested, the Committee may permit the Participant to deliver a conditional exercise election, in a form approved by the Committee, whereby the Participant
irrevocably elects to exercise the Tier II Option and/or the Tier IV Option as of such Liquidity Event, subject to the conditions precedent that (x) the Liquidity Event actually occurs and (y) the Tier II Option and Tier IV Option become
vested upon such Liquidity Event. 
 (c)    Vesting of the Tier III Option. Subject to the Participant’s
continued Employment through the applicable vesting date, the Tier III Option shall vest if, on or after a Liquidity Event and on or prior to July 3, 2022, Sponsor shall have received net cash proceeds generated together with all Sponsor
Outflows received, in each case, in respect of all Shares sold by it or in connection with an Asset Sale, as applicable, that results in either (A) a return of at least 2.5 times the amount of the Sponsor’s cumulative invested capital in
respect of such sold Shares or (B) an annual internal rate of return of at least twenty percent (20%) on the Sponsor’s cumulative invested capital in respect of such sold Shares. For the avoidance of doubt, following July 3, 2022, the
Tier III Option, to the extent not then vested, shall not be eligible to become vested and shall automatically be immediately canceled without consideration. In connection with any Liquidity Event in which the Tier III Option is expected to become
vested, the Committee may permit the Participant to deliver a conditional exercise election, in a form approved by the Committee, whereby the Participant irrevocably elects to exercise the Tier III Option as of such Liquidity Event, subject to the
conditions precedent that (x) the Liquidity Event actually occurs and (y) the Tier III Option becomes vested upon such Liquidity Event. 

(d)     Termination of Employment. If the Participant’s Employment terminates for any reason,
the Options, to the extent not then vested and exercisable, shall automatically be immediately canceled without consideration and the Vested Portion of an Option shall remain exercisable for the period set forth in Section 4(a). 

 (e)    Exit by Blackstone. Notwithstanding any provision of
Section 3(b) or Section 3(c) to the contrary, if the Sponsor shall cease to own any Shares, each of the Tier II Option, the Tier III Option and the Tier IV Option, to the extent not then vested and exercisable, shall automatically be
immediately canceled without consideration. 
 4.    Exercise of Options. 

(a)    Period of Exercise. Subject to the provisions of the Plan and this Agreement, the Participant may exercise
all or any part of the Vested Portion of an Option at any time prior to the Expiration Date. Notwithstanding the foregoing, if the Participant’s Employment terminates prior to the Expiration Date, the Vested Portion of an Option shall remain
exercisable for the period set forth below: 
 (i) Death or Disability. If the Participant’s Employment
terminates due to the Participant’s death or Disability, the Participant may exercise the Vested Portion of an Option for a period ending on the earlier of (x) the one year anniversary of such termination of Employment and (y) the
Expiration Date; 
 (ii) Termination by the Company Other than for Cause and Other than Due to Death or Disability or by
the Participant for Good Reason. If the Participant’s Employment is terminated (x) by the Company or any of its Subsidiaries other than for Cause and not due to the Participant’s death or Disability or (y) by the Participant
for Good Reason, in each case, the Participant may exercise the Vested Portion of an Option for a period ending on the earlier of (A) the 90th day following such termination of Employment and
(B) the Expiration Date; 
 (iii) Termination by the Participant without Good Reason When Grounds for Cause Do Not
Exist. If the Participant’s Employment is terminated by the Participant without Good Reason at a time when grounds do not exist for a termination by the Company or any of its Subsidiaries for Cause, the Participant may exercise the Vested
Portion of an Option for a period ending on the earlier of (A) the 30th day following such termination of Employment and (B) the Expiration Date; and 

(iv) Termination by the Company for Cause; Resignation by the Participant without Good Reason when Grounds for Cause Exist;

(b)    Method of Exercise. 

(i) Subject to Section 4(a) of this Agreement and Section 6(d) of the Plan, the Vested Portion of an Option may be
exercised by delivering to the Company at its 

 
principal office written notice of intent to so exercise; provided that, the Option may be exercised with respect to whole Shares only. Such notice shall specify the number of Shares for
which the Option is being exercised and shall be accompanied by payment in full of the Exercise Price. The payment of the Exercise Price may be made at the election of the Participant (A) in cash or its equivalent (e.g., by check or, if
permitted by the Committee, a full-recourse promissory note), (B) to the extent permitted by the Committee in its sole discretion, (1) in Shares having a Fair Market Value equal to the aggregate Exercise Price for the Shares being purchased and
satisfying such other requirements as may be imposed by the Committee; provided, that such Shares have been held by the Participant for any period as established from time to time by the Committee in order to avoid adverse accounting treatment
applying generally accepted accounting principles, (2) if there is a public market for the Shares at such time, subject to such rules as may be established by the Committee, through the delivery of irrevocable instructions to a broker to sell
Shares obtained upon the exercise of the Option and to deliver promptly to the Company an amount out of the proceeds of such sale equal to the aggregate exercise price for the Shares being purchased, (3) using a net settlement mechanism whereby
the number of Shares delivered upon the exercise of the Option will be reduced by a number of Shares that has a Fair Market Value equal to the Exercise Price, or (4) using any combination of the permitted exercise methods, or (C) following
the date of a Change in Control or a Liquidity Event, using a net settlement mechanism whereby the number of Shares delivered upon the exercise of the Option will be reduced by a number of Shares that has a Fair Market Value equal to the Exercise
Price provided that, for the avoidance of doubt, the Participant tenders cash or its equivalent to pay any applicable withholding or other applicable taxes. The Participant shall not have any rights to dividends or other rights of a stockholder with
respect to Shares subject to an Option until the Participant has given written notice of exercise of the Option, paid in full for such Shares and, if applicable, has satisfied any other conditions imposed by the Committee pursuant to the Plan,
provided, in each case, that the Participant tenders cash or its equivalent to pay any applicable withholding or other applicable taxes (unless otherwise permitted by the Committee). 

(ii) Notwithstanding any other provision of the Plan or this Agreement to the contrary, absent an available exemption to
registration or qualification, an Option may not be exercised prior to the completion of any registration or qualification of an Option or the Shares under applicable state and federal securities or other laws, or under any ruling or regulation of
any governmental body or national securities exchange that the Committee shall in its sole discretion determine to be necessary or advisable; provided, that the Company shall use commercially reasonable efforts to take such actions as are necessary
and appropriate to register or qualify the Shares subject to the Option so it may be exercised. 
 (iii) Upon the
Company’s determination that an Option has been validly exercised as to any of the Shares, the Company may issue certificates in the Participant’s name for such Shares or the Company may cause the appropriate entries to be made in the
register of members of the Company in respect of the issuance of such shares. However, neither the Committee nor the Company shall be liable to the Participant for damages relating to any delays in issuing the certificates to the Participant or
making the 

 
entries in the register of members of the Company, any loss by the Participant of the certificates or entries, or any mistakes or errors in the issuance of the certificates or in the certificates
themselves or entries. 
 (iv) In the event of the Participant’s death, the Vested Portion of an Option shall remain
exercisable by the Participant’s executor or administrator, or the person or persons to whom the Participant’s rights under this Agreement shall pass by will or by the laws of descent and distribution as the case may be, to the extent set
forth in Section 4(a) of this Agreement. Any heir or legatee of the Participant shall take rights herein granted subject to the terms and conditions hereof. 

5.    Confidential Information; Post-Employment Restrictive Covenants. 

(a)    This Agreement. The terms of this Agreement constitute confidential information, which the Participant shall
not disclose to anyone other than the Participant’s spouse, attorneys, tax advisors, or as required by law. The Company may disclose the terms of this Agreement subject to applicable law. The terms of this Section 5 shall supplement, but
not supersede or replace, any similar restrictive covenants to which the Participant has otherwise agreed to be bound. 

(b)    Company Property. All written materials, records, data, and other documents prepared or possessed by the
Participant during the Participant’s Employment are the Company’s property. All memoranda, notes, records, files, correspondence, drawings, manuals, models, specifications, computer programs, maps, and all other documents, data, or
materials of any type embodying such information, ideas, concepts, improvements, discoveries, and inventions are the Company’s property. 

(i) All information, ideas, concepts, improvements, discoveries, and inventions that are conceived, made, developed, or
acquired by the Participant individually or in conjunction with others during the Participant’s Employment (whether during business hours and whether on the Company’s or any of its Subsidiaries’ premises or otherwise) which relate to
the Company’s or any of its Subsidiaries’ business, products, or services are the Company’s property. The Participant agrees to make prompt and full disclosure to the Company or its Subsidiaries, as the case may be, of all ideas,
discoveries, trade secrets, inventions, innovations, improvements, developments, methods of doing business, processes, programs, designs, analyses, drawings, reports, data, software, firmware, logos and all similar or related information (whether or
not patentable and whether or not reduced to practice) that relate to the Company’s or its Subsidiaries’ actual or anticipated business, research and development, or existing or future products or services and that are conceived,
developed, acquired, contributed to, made, or reduced to practice by the Participant (either solely or jointly with others) during the Participant’s Employment and for a period of one (1) year thereafter (collectively, “Work
Product”). Any copyrightable work falling within the definition of Work Product shall be deemed a “work made for hire” under the copyright laws of the United States, and ownership of all rights therein shall vest in the Company or one
or more of its Subsidiaries. To the extent that any Work Product is not deemed to be a “work made for hire,” the Participant hereby assigns and agrees to assign to the Company 

 
or such Subsidiary all right, title and interest, including without limitation, the intellectual property rights that the Participant may have in and to such Work Product. The Participant shall
promptly perform all actions reasonably requested by the Committee (whether during or after the Employment period) to establish and confirm the Company’s or such Subsidiary’s ownership (including, without limitation, providing testimony
and executing assignments, consents, powers of attorney, and other instruments). 
 (ii) At the termination of the
Participant’s Employment with the Company or any of its Subsidiaries for any reason, the Participant shall return all of the Company’s or any of its Subsidiaries’ property to the Company. 

(c)    Confidential Information; Non-Disclosure. The Participant
acknowledges that the business of the Company and its Subsidiaries is highly competitive and that the Company has provided and will provide the Participant with access to Confidential Information relating to the business of the Company and its
Subsidiaries. “Confidential Information” means and includes the Company’s confidential and/or proprietary information and/or trade secrets that have been developed or used and/or will be developed and that cannot be obtained readily
by third parties from outside sources. Confidential Information includes, by way of example and without limitation, the following: information regarding customers, employees, contractors, and the industry not generally known to the public;
strategies, methods, books, records, and documents; technical information concerning products, equipment, services, and processes; procurement procedures and pricing techniques; the names of and other information concerning customers, investors, and
business affiliates (such as contact name, service provided, pricing for that customer, amount of services used, credit and financial data, and/or other information relating to the Company’s relationship with that customer); pricing strategies
and price curves; plans and strategies for expansion or acquisitions; budgets; customer lists; research; weather data; financial and sales data; trading terms; evaluations, opinions, and interpretations of information and data; marketing and
merchandising techniques; prospective customers’ names and marks; grids and maps; electronic databases; models; specifications; computer programs; internal business records; contracts benefiting or obligating the Company; bids or proposals
submitted to any third party; technologies and methods; training methods and training processes; organizational structure; salaries of personnel; payment amounts or rates paid to consultants or other service providers; and other such confidential or
proprietary information. The Participant acknowledges that this Confidential Information constitutes a valuable, special, and unique asset used by the Company or its Subsidiaries in their business to obtain a competitive advantage over their
competitors. The Participant further acknowledges that protection of such Confidential Information against unauthorized disclosure and use is of critical importance to the Company and its Subsidiaries in maintaining their competitive position. 

(i) The Participant also will have access to, or knowledge of, Confidential Information of third parties, such as actual and
potential customers, suppliers, partners, joint venturers, investors, financing sources and the like, of the Company and its Subsidiaries. 

(ii) The Participant agrees that the Participant will not, at any time during or after the Participant’s Employment with
the Company, make any unauthorized disclosure of any Confidential Information of the Company or its Subsidiaries, or make 

 
any use thereof, except in the carrying out responsibilities related to the Participant’s Employment or as may be lawfully required by a court or other governmental authority. The
Participant also agrees to preserve and protect the confidentiality of third party Confidential Information to the same extent, and on the same basis, as the Company’s Confidential Information. 

(iii) Nothing in this Agreement shall prohibit or impede the Participant from communicating, cooperating or filing a complaint
with any U.S. federal, state or local governmental or law enforcement branch, agency or entity (collectively, a “Governmental Entity”) with respect to possible violations of any U.S. federal, state or local law or regulation, or
otherwise making disclosures to any Governmental Entity, in each case, that are protected under the whistleblower provisions of any such law or regulation, provided that in each case such communications and disclosures are consistent with applicable
law. The Participant understands and acknowledges that an individual shall not be held criminally or civilly liable under any Federal or State trade secret law for the disclosure of a trade secret that is made (i) in confidence to a Federal,
