 WHEREAS, the Company desires to continue the employment of the
Executive as the Chief Executive Officer of the Company and to pay all of the Executive’s compensation other than certain equity awards described in this Agreement; and 

WHEREAS, Parent desires the Executive to continue to be its Chief Executive Officer, to grant the Executive certain equity awards

 WHEREAS,
the Company, Parent and the Executive desire to enter into this Agreement as to the terms of the Executive’s employment with the Company. 

NOW, THEREFORE, in consideration of the foregoing, of the mutual promises contained herein and of other good and valuable
consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto hereby agree as follows: 
 1. POSITION
AND DUTIES. 
 (a) During the Employment Term (as defined in Section 2 hereof), the Executive shall serve as the Chief
Executive Officer of the Company and Parent. In this capacity, the Executive shall have the duties, authorities and responsibilities commensurate with the duties, authorities and responsibilities of persons in similar capacities in similarly sized
companies, and such other duties, authorities and responsibilities as may reasonably be assigned to the Executive that are not inconsistent with the Executive’s position as Chief Executive Officer of the Company. The Executive shall serve as a
member of the Board of Managers (or similar governing body) of Parent (the “Board”) and of the Board of Directors of the Company. The Executive’s principal place of employment with the Company shall be in Pittsburgh,
Pennsylvania, provided that the Executive understands and agrees that the Executive will be required to travel frequently for business purposes. The Executive shall report directly to the Board. 

(b) During the Employment Term, the Executive shall devote all of the Executive’s business time, energy, business judgment, knowledge and
skill and the Executive’s reasonable best efforts to the performance of the Executive’s duties with the Company, provided that the foregoing shall not prevent the Executive from (i) serving on the boards of directors of
non-profit organizations and, with the prior written approval of the Board, other for profit companies; 

  
 1 

 
provided that the Executive shall be permitted to serve on the board of directors of Allegheny Energy, Inc. or FirstEnergy Corp., (ii) participating in charitable, civic, educational,
professional, community or industry affairs, and (iii) managing the Executive’s passive personal investments so long as such activities in the aggregate do not violate Section 10 hereof, interfere or conflict with the
Executive’s duties hereunder or create a business or fiduciary conflict. 
 2. EMPLOYMENT TERM. The Company agrees to employ the
Executive pursuant to the terms of this Agreement, and the Executive agrees to be so employed, from the Effective Date until June 30, 2017 (the “Employment Term”). Notwithstanding the foregoing, the Executive’s employment
hereunder may be earlier terminated in accordance with Section 7 hereof, subject to Section 8 hereof. 
 3. BASE
SALARY. The Company agrees to pay the Executive a base salary at an annual rate of not less than $1,000,000, payable in accordance with the regular payroll practices of the Company, but not less frequently than monthly. The Executive’s base
salary shall be subject to annual review by the Board (or a committee thereof) during the first ninety (90) days of each calendar year, and the base salary in respect of such calendar year may be increased above, but not decreased below, its
level for the preceding calendar year, by the Board. The base salary as determined herein and adjusted from time to time shall constitute “Base Salary” for purposes of this Agreement. 

4. ANNUAL BONUS. 
 (a)
During the Employment Term, the Executive shall be eligible for an annual cash performance bonus (an “Annual Bonus”) in respect of each calendar year that ends during the Employment Term, to the extent earned based on performance
against objective performance criteria. The performance criteria for any particular calendar year shall be determined in good faith by the Board, after consultation with the Executive, no later than ninety (90) days after the commencement of
such calendar year. The Executive’s targeted Annual Bonus for a calendar year shall equal 150% of the Executive’s Base Salary for such calendar year (the “Target Bonus”) if target levels of performance for such year are
achieved, with greater or lesser amounts (including zero) paid for performance above and below target (such greater and lesser amounts to be determined by a formula established by the Board for such year when it establishes the targets and
performance criteria for such year). The Executive’s Target Bonus shall be subject to annual review by the Board (or a committee thereof) during the first ninety (90) days of each calendar year, and the Target Bonus for such calendar year
may be increased above, but not decreased below, the levels for the preceding calendar year, by the Board. 
 (b) The Executive’s
Annual Bonus for a calendar year shall be determined by the Board after the end of the applicable calendar year based on the level of achievement of the applicable performance criteria, and shall be paid to the Executive in the calendar year
following the calendar year to which such Annual Bonus relates at the same time annual bonuses are paid to other senior executives of the Company, subject to continued employment at the time of payment (except as otherwise provided in
Section 8 hereof).

 5. EQUITY AWARD. Upon the Effective Date, the Executive shall be granted by Parent an
equity award on such terms and conditions as are set forth in the Subscription Agreement attached as Exhibit A hereto.  

6. EMPLOYEE BENEFITS. 

(a) BENEFIT PLANS. During the Employment Term, the Executive shall be entitled to participate in any employee benefit plan that the
Company, Parent or any of their direct or indirectly controlled subsidiaries (each an “Affiliate”) has adopted or may adopt, maintain or contribute to and which benefit any of the senior executives of the Company, Parent or any
Affiliate, on a basis no less favorable than that applicable to any such senior executives, subject to satisfying the applicable eligibility requirements, except to the extent such plans are duplicative of the benefits otherwise provided hereunder.
The Executive’s participation in any such employee benefit plan shall be subject to the terms of the applicable plan documents and generally applicable Company policies. Notwithstanding the foregoing, the Company may modify or terminate any
employee benefit plan at any time, if and to the extent allowed pursuant to the terms of such plan, provided that any such amendment may have no more adverse affect on the Executive than on any other participant in such plan. The Company may provide
perquisites to the Executive at the discretion of the Board. 
 (b) VACATIONS. During the Employment Term, the Executive shall be
entitled to paid vacation in accordance with the Company’s policy on accrual and use applicable to employees as in effect from time to time based; provided that the Executive’s vacation accrual shall be calculated as if the
Executive had thirty (30) years of employment with the Company. 
 (c) RETIREMENT BENEFITS. The Company shall provide the
Executive with a retirement benefit in accordance with Exhibit B attached hereto (the “Retirement Benefit”). For purposes of determining the Executive’s retirement benefit, (i) on the Effective Date, the
Executive shall be treated as having eighteen (18) Years of Service Credit with the Company, (ii) if the Executive is employed by the Company on June 17, 2013, the Executive shall be granted an additional six (6) Years of Service
Credit with the Company (for a total of twenty-four (24) Years of Service Credit with the Company), and (iii) if the Executive is employed by the Company on June 17, 2014, the Executive shall be granted an additional six
(6) Years of Service Credit with the Company (for a total of thirty (30) Years of Service Credit with the Company). Upon a Change in Control while the Executive is employed by the Company, the Executive shall be granted Years of Service
Credit with the Company sufficient to reach an aggregate of thirty (30) Years of Service Credit with the Company. For the sake of clarity, in no event shall the Executive receive more than an aggregate of thirty (30) Years of Service
Credit with the Company. Notwithstanding any other provision herein to the contrary, in the event that the Executive’s employment is terminated (A) by the Company for Cause, or (B) by the Executive without Good Reason, in either case,
prior to June 17, 2013, the Executive shall be deemed to have zero (0) Years of Service Credit with the Company for purposes of this Section 6(c) and Exhibit B attached hereto. 

(d) BUSINESS EXPENSES. Upon presentation of reasonable substantiation and documentation as the Company may specify from time to time,
the Executive shall be reimbursed in accordance with the Company’s expense reimbursement policies as in effect from 

  
 3 

 
time to time, for all reasonable out-of-pocket business expenses incurred and paid by the Executive during the Employment Term and in connection with the performance of the Executive’s
duties hereunder. 
 (e) LEGAL FEES. Upon presentation of an invoice therefor, the Company shall pay or reimburse the
Executive’s reasonable counsel fees incurred in connection with the negotiation and documentation of this Agreement and the other documents ancillary thereto. 

7. TERMINATION. The Executive’s employment and the Employment Term shall terminate on the first of the following to occur: 

(a) DISABILITY. Upon ten (10) days’ prior written notice by the Company to the Executive of termination due to
Disability. For purposes of this Agreement, “Disability” shall be defined as the inability of the Executive to have performed the Executive’s material duties hereunder due to a physical or mental injury, infirmity or
incapacity, which inability shall continue for one hundred and twenty (120) consecutive days or for one hundred eighty (180) days (including weekends and holidays) in any 365-day period as determined by the Board in its reasonable
discretion. The Executive shall cooperate in all respects with the Company if a question arises as to whether the Executive has become disabled (including, without limitation, submitting to reasonable examinations by one or more medical doctors and
other health care specialists selected by the Company and authorizing such medical doctors and other health care specialists to discuss the Executive’s condition with the Company). 

(b) DEATH. Automatically upon the date of death of the Executive. 

(c) CAUSE. Immediately upon written notice by the Company to the Executive of a termination for Cause. “Cause” shall
mean the Executive’s (i) continued failure to follow the lawful directives of the Board after written notice from the Board and a period of no less than thirty (30) days to cure such failure; (ii) willful misconduct or gross
negligence in the performance of the Executive’s duties; (iii) conviction of, or pleading of guilty or nolo contendere to, a felony; (iv) material violation of a material Company policy that is not cured within fifteen
(15) days of written notice from the Board; (v) performance of any material act of theft, embezzlement, fraud or misappropriation of or in respect of the Company’s property; (vi) continued failure to cooperate in any audit or
investigation of financial or business practices of the Company after written request for cooperation from the Board and a period of no less than ten (10) days to cure such failure; or (vii) breach of any of the restrictive covenants set
forth in Section 10 hereof or in any other written agreement between the Executive and the Company and/or its affiliates that causes material and demonstrable harm to the Company and that is not cured within fifteen (15) days of
written notice from the Board (a “Material Covenant Violation”). 
 For purposes of this Section 7(c), no act,
or failure to act, on the part of the Executive shall be considered “willful” unless it is done, or omitted to be done, by the Executive in bad faith or without reasonable belief that the Executive’s action or omission was in the best
interests of the Company. Any act, or failure to act, based upon (A) authority given pursuant to a resolution duly adopted by the Board or the board of directors of the Company or (B) the advice of counsel for the Company or Parent shall
be conclusively presumed to be done, or omitted to 

  
 4 

 
be done, by the Executive in good faith and in the best interests of the Company. The cessation of employment of the Executive shall not be deemed to be for Cause unless and until there shall
have been delivered to the Executive a copy of a resolution duly adopted by the affirmative vote of not less than a majority of the entire membership of the Board (excluding the Executive, if the Executive is a member of the Board) at a meeting of
the Board called and held for such purpose (after reasonable notice is provided to the Executive and the Executive is given an opportunity, together with counsel for the Executive, to be heard before the Board), finding that, in the good faith
opinion of the Board, the Executive is guilty of the conduct described in one or more of clauses (i) through (vii) of the preceding paragraph, and specifying the particulars thereof in detail. 

(d) WITHOUT CAUSE. Immediately upon written notice by the Company to the Executive of an involuntary termination without Cause (other
than for death or Disability). 
 (e) GOOD REASON. Upon written notice by the Executive to the Company of a termination for Good
Reason. “Good Reason” shall mean the occurrence of any of the following events, without the express written consent of the Executive, unless such events are fully corrected in all material respects by the Company or Parent (as
applicable) within thirty (30) days following written notification by the Executive to the Company of the occurrence of one of the reasons set forth below: (i) the material diminution in the Executive’s position, duties or authorities
or assignment of duties materially inconsistent with the Executive’s position with Parent, including but not limited to the Executive ceasing to be the sole Chief Executive Officer of Parent, and a member of the Board; (ii) the
Executive’s relocation of the Executive’s primary work location by more than thirty-five (35) miles from its then current location; (iii) a reduction in Base Salary or Target Bonus; or (iv) the Company’s material breach
of this Agreement. The Executive shall provide the Company with a written notice detailing the specific circumstances alleged to constitute Good Reason within ninety (90) days after the Executive first gains actual knowledge of the occurrence
of such circumstances, and actually terminate employment within thirty (30) days following the expiration of the Company’s thirty (30)-day correction period described above. Otherwise, any claim of such circumstances as “Good
Reason” shall be deemed irrevocably waived by the Executive. 
 (f) WITHOUT GOOD REASON. Upon one years’ prior written
notice by the Executive to the Company of the Executive’s voluntary termination of employment without Good Reason (which the Company may, in its sole discretion, make effective earlier than the expiration of the notice period). In such event,
the last day of employment as provided in the notice period, or an earlier date at the Company’s option, shall be the Executive’s termination date for all purposes of this Agreement, including without limitation, the termination date for
determining termination benefits pursuant to Section 8 hereof. The Company’s election to accelerate the Executive’s termination date shall not be considered a termination by the Company without Cause or constitute Good Reason
hereunder. In addition, the Company may transition Executive’s duties and responsibilities to others during the notice period and such diminution of duties and responsibilities shall not constitute Good Reason as provided for herein. 

(g) EXPIRATION OF EMPLOYMENT TERM. Upon the expiration of the Employment Term on July 1, 2017 pursuant to Section 2
hereof. For the sake of clarity, such expiration shall occur by the terms of this Agreement (unless sooner terminated) and neither party is required to give notice with respect to such expiration.

 8. CONSEQUENCES OF TERMINATION. 

(a) DEATH. In the event that the Executive’s employment and the Employment Term ends on account of the Executive’s death, the
Executive’s estate shall be entitled to the following (with the amounts due under Sections 8(a)(i) through 8(a)(v) hereof to be paid, unless otherwise provided below, within sixty (60) days following termination of
employment, or such earlier date as may be required by applicable law): 
 (i) any unpaid Base Salary through the date of termination;

 (ii) any Annual Bonus earned but unpaid with respect to the calendar year ending on or preceding the date of termination; 

(iii) an amount equal to the pro-rata portion of the Executive’s Target Bonus for the calendar year of termination (determined by
multiplying the Target Bonus for the year of termination by a fraction, the numerator of which is the number of days during the calendar year of termination that the Executive is employed by the Company and the denominator of which is 365);
provided that to the extent that the payment of such amount constitutes “nonqualified deferred compensation” for purposes of “Code Section 409A” (as defined in Section 24 hereof), such payment shall be
made on the sixtieth (60th) day following such termination; 
 (iv) reimbursement
for any unreimbursed business expenses incurred through the date of termination; 
 (v) payment in respect of any accrued but unused
vacation time in accordance with Company policy; 
 (vi) subject to Section 6(c), the Retirement Benefit; and

compensation arrangement or benefit, equity or fringe benefit plan or program or grant or this Agreement (collectively, Sections 8(a)(i) through 8(a)(vii) hereof shall be hereafter referred to as the “Accrued
Benefits”). 
 (b) DISABILITY. In the event that the Executive’s employment and/or Employment Term ends on account of
the Executive’s Disability, the Company shall pay or provide the Executive with the Accrued Benefits. 
 (c) TERMINATION FOR CAUSE
OR WITHOUT GOOD REASON OR AS A RESULT OF AN EXPIRATION OF THE EMPLOYMENT TERM. If the Executive’s employment is terminated (x) by the Company for Cause, (y) by the Executive without Good Reason, or (z) as a result of the
expiration of the Employment Term, the Company shall pay to the Executive the Accrued Benefits; provided that, in the event of a termination for Cause, the Executive shall not be entitled to the benefits described in
Sections 8(a)(ii) and 8(a)(iii); and provided further that, in the event of a resignation by the Executive without Good Reason with less than one year’s notice, the Executive shall not be entitled to the
benefits described in Section 8(a)(iii). 

  
 6 

 (d) TERMINATION WITHOUT CAUSE OR FOR GOOD REASON. If the Executive’s employment by
the Company is terminated (x) by the Company other than for Cause (and, for the sake of clarity, other than due to the Executive’s death or Disability) pursuant to Section 7(d) hereof or (y) by the Executive for Good
Reason, the Company shall pay or provide the Executive with the following, subject to the provisions of Section 24 hereof: 

(i) the Accrued Benefits; 
 (ii)
subject to the Executive’s not engaging in a Material Covenant Violation or a material breach of Section 11 hereof that is not cured within fifteen (15) days of written notice from the Board (a “Material Cooperation
Violation”), the Executive shall be entitled to one (but not both) of the following payments, as applicable: 
 (A) if the
Executive’s employment is terminated pursuant to this Section 8(d) prior to June 17, 2013, an amount equal to three (3) multiplied by the sum of the Executive’s Base Salary, and Target Bonus for the year of
termination (the “Clause A Severance Amount”), paid in equal monthly installments for a period of twenty-four (24) months following such termination; provided that to the extent that the payment of any amount constitutes
“nonqualified deferred compensation” for purposes of Code Section 409A, any such payment scheduled to occur during the first sixty (60) days following the termination of employment shall not be paid until the sixtieth (60th) day following such termination and shall include payment of any amount that was otherwise scheduled to be paid prior thereto; or 

(B) if the Executive’s employment is terminated pursuant to this Section 8(d) on or after June 17, 2013, an amount
equal to two (2) multiplied by the sum the Executive’s Base Salary, and Target Bonus for the year of termination (the “Clause B Severance Amount”), paid in equal monthly installments for a period of twenty-four
(24) months following such termination; provided that to the extent that the payment of any amount constitutes “nonqualified deferred compensation” for purposes of Code Section 409A, any such payment scheduled to occur
during the first sixty (60) days following the termination of employment shall not be paid until the sixtieth (60th) day following such termination and shall include payment of any amount
that was otherwise scheduled to be paid prior thereto; and 
 (iii) subject to (A) the Executive’s timely election of continuation
coverage under the Consolidated Omnibus Budget Reconciliation Act of 1985, as amended (“COBRA”), (B) the Executive’s continued copayment of premiums at the same level and cost to the Executive as if the Executive were an
employee of the Company (excluding, for purposes of calculating cost, an employee’s ability to pay premiums with pre-tax dollars), (C) the Executive’s not engaging in a Material Covenant Violation or a Material Cooperation Violation,
and (D) the Company not being subject to material tax or other penalties, continued participation in the Company’s group health plan (to the extent permitted under applicable law) which covers the Executive (and the Executive’s
eligible dependents) for a period of thirty-six (36) months (if the Clause A Severance Amount is payable) or twenty-four (24) months (if the Clause B Severance Amount is payable) following the Executive’s date of termination, at the
Company’s 

  
 7 

 
expense, provided that if the Company’s group health plan is self-insured, the Company will report to the appropriate tax authorities taxable income to the Executive equal to the
portion of the deemed cost of such participation (based on applicable COBRA rates) not paid by the Executive; and provided, further, that in the event that the Executive obtains other employment that offers group health benefits, such
continuation of coverage by the Company under this Section 8(d)(iii) shall immediately cease. 
 Payments and benefits provided in this
Section 8(d) shall be in lieu of any termination or severance payments or benefits for which the Executive may be eligible under any of the plans, policies or programs of the Company or under the Worker Adjustment Retraining Notification
Act of 1988 or any similar state statute or regulation. 
 (e) CHANGE IN CONTROL. 

(i) This Section 8(e) shall apply if the Executive’s employment by the Company is terminated (x) by the Company other
than for Cause pursuant to Section 7(d) hereof, or (y) by the Executive for Good Reason, in either case, during the Employment Term and the two (2)-year period commencing upon a Change in Control. Subject to the Executive’s not
engaging in a Material Covenant Violation or a Material Cooperation Violation, upon a termination described in the preceding sentence, the Executive shall receive the benefits set forth in Section 8(d) hereof, except that in lieu of
receiving the Clause A Severance Amount or the Clause B Severance Amount, as applicable, in installments as contemplated under Sections 8(d)(ii)(A) and 8(d)(ii)(B) hereof, the Executive shall receive a lump sum payment equal to the
Clause A Severance Amount or the Clause B Severance Amount, as applicable, on the date of such termination; provided that to the extent that the payment of the applicable amount constitutes “nonqualified deferred compensation” for
purposes of Code Section 409A, such payment shall be made on the sixtieth (60th) day following such termination. 

(ii) For purposes of this Agreement, the term “Change in Control” shall mean the consummation of the first transaction
following the Effective Date, whether in a single transaction or in a series of related transactions, in which any individual, entity or group (within the meaning of Section 13(d)(3) or 14(d)(2) of the Securities Exchange Act of 1934, as
amended) (a “Group”), other than Bain Capital Partners, any private equity fund managed by it, or any Group which includes Bain Capital Partners or any private equity fund managed by it, (A) acquires (whether by merger,
consolidation, or transfer or issuance of equity interests or otherwise) equity interests of Parent (or any surviving or resulting entity) representing more than fifty percent (50%) of the outstanding voting securities or economic value of
Parent (or any surviving or resulting entity), or (B) acquires assets constituting all or substantially all (more than eighty percent (80%)) of the assets of Parent and its subsidiaries (as determined on a consolidated basis). 

(f) CODE SECTION 280G. To the extent that any amount or benefit that may be paid or otherwise provided to or in respect of the
Executive by the Company or any affiliated company, whether pursuant to this Agreement or otherwise, exceeds the limitations of Section 280G of the Internal Revenue Code of 1986, as amended (the “Code”) such that an excise tax
would be imposed under Section 4999 of the Code, the provisions of Exhibit C attached hereto shall be applicable. 

  
 8 

 (g) OTHER OBLIGATIONS. Upon any termination of the Executive’s employment with the
Company, the Executive shall promptly resign from the Board and any other position as an officer, director or fiduciary of the Company, Parent and any Affiliate. 

9. RELEASE; NO MITIGATION; NO SET-OFF. Any and all amounts payable and benefits or additional rights provided pursuant to this
Agreement beyond the Accrued Benefits (other than the amount described in Section 8(a)(iii) hereof) shall only be payable if the Executive delivers to the Company and does not revoke a general release of claims in favor of the Company in
substantially the form of Exhibit D attached hereto. Such release shall be executed and delivered (and no longer subject to revocation, if applicable) within sixty (60) days following termination. In no event shall the Executive be
obligated to seek other employment or take any other action by way of mitigation of the amounts payable to the Executive under any of the provisions of this Agreement, nor shall the amount of any payment hereunder be reduced by any compensation
earned by the Executive as a result of employment by a subsequent employer (except as provided in Section 8(d)(iii) hereof). The Company’s obligations to pay the Executive amounts hereunder shall not be subject to set-off,
counterclaim or recoupment of amounts owed by the Executive to the Company or any of its affiliates. 
 10. RESTRICTIVE COVENANTS.

 (a) CONFIDENTIALITY. During the course of the Executive’s employment with the Company and its Affiliates, the Executive
will learn confidential information regarding Parent and its Affiliates (the “Parent Group”). The Executive agrees that the Executive shall not, directly or indirectly, use, make available, sell, disclose or otherwise communicate to
any person, other than in the course of the Executive’s assigned duties and for the benefit of the Parent Group, either during the period of the Executive’s employment or at any time thereafter, any business and technical information or
trade secrets, nonpublic, proprietary or confidential information, knowledge or data relating to the Parent Group, or received from third parties subject to a duty on the Parent Group’s part to maintain the confidentiality of such information
and to use it only for certain limited purposes, in each case which shall have been obtained by the Executive during the Executive’s employment by the Parent Group. The foregoing shall not apply to information that (i) was known to the
public prior to its disclosure to the Executive; (ii) becomes generally known to the public subsequent to disclosure to the Executive through no wrongful act of the Executive or any representative of the Executive; or (iii) the Executive
is required to disclose by applicable law, regulation or legal process (provided that the Executive provides the Company with prior notice of the contemplated disclosure and cooperates with the Company at its expense in seeking a protective
order or other appropriate protection of such information). The terms and conditions of this Agreement shall remain strictly confidential, and the Executive hereby agrees not to disclose the terms and conditions hereof to any person or entity, other
than immediate family members, legal advisors or personal tax or financial advisors, or prospective future employers solely for the purpose of disclosing the limitations on the Executive’s conduct imposed by the provisions of this
Section 10 who, in each case, shall be instructed by the Executive to keep such information confidential. 
 (b)
NONCOMPETITION. The Executive acknowledges that the Executive performs services of a unique nature for the Parent Group that are irreplaceable, and that the Executive’s performance of such services to a competing business will result in
irreparable harm 

  
 9 

 
to the Parent Group. Accordingly, during the Executive’s employment hereunder and for a period of two (2) years thereafter, the Executive agrees that the Executive will not, directly or
indirectly, own, manage, operate, control, be employed by (whether as an employee, consultant, independent contractor or otherwise, and whether or not for compensation) or render services to any person, firm, corporation or other entity, in whatever
form, engaged in competition with any material business of the Parent or any Affiliate or in any other material business in which the Parent or any Affiliate has taken material steps and has material plans, on or prior to the date or termination, to
be engaged in on or after such date, in any locale of any country in which the Company or such Affiliate conducts business. Notwithstanding the foregoing, nothing herein shall prohibit the Executive from being a passive owner of not more than one
percent (1%) of the equity securities of a publicly traded corporation engaged in a business that is in competition with Parent or any of its Affiliates, so long as the Executive has no active participation in the business of such corporation.

 (c) NONSOLICITATION; NONINTERFERENCE. During the Executive’s employment with the Company and for a period of two
(2) years thereafter, the Executive agrees that the Executive shall not, except in the furtherance of the Executive’s duties hereunder, directly or indirectly, individually or on behalf of any other person, firm, corporation or other
entity, (i) solicit, aid or induce any customer of Parent or an Affiliate to purchase goods or services then sold by Parent or any Affiliate from another person, firm, corporation or other entity or assist or aid any other persons or entity in
identifying or soliciting any such customer, (ii) solicit, aid or induce any employee, representative or agent of Parent or any Affiliate to leave such employment or retention or, in the case of employees, to accept employment with or render
services to or with any other person, firm, corporation or other entity unaffiliated with Parent or any Affiliate, or hire or retain any such employee, or take any action to materially assist or aid any other person, firm, corporation or other
entity in identifying, hiring or soliciting any such employee, or (iii) interfere, or aid or induce any other person or entity in interfering, with the relationship between Parent or any Affiliate and any of their respective vendors, joint
venturers or licensors. An employee, representative or agent shall be deemed covered by this Section 10(c) while so employed or retained and for a period of six (6) months thereafter. Notwithstanding the foregoing, the provisions of
this Section 10(c) shall not be violated by general advertising or solicitation not specifically targeted at Parent or Affiliate-related individuals or entities. 

(d) INVENTIONS. (i) The Executive acknowledges and agrees that all ideas, methods, inventions, discoveries, improvements, work
products, developments or works of authorship (“Inventions”), whether patentable or unpatentable, (A) that relate to the Executive’s work with the Parent Group, made or conceived by the Executive, solely or jointly with
others, during the Employment Term, or (B) suggested by any work that the Executive performs in connection with the Parent Group, either while performing the Executive’s duties with the Parent Group or on the Executive’s own time,
shall belong exclusively to the Company (or its designee), whether or not patent applications are filed thereon. The Executive will keep full and complete written records (the “Records”), in the manner prescribed by the Company, of
all Inventions, and will promptly disclose all Inventions completely and in writing to the Company. The Records shall be the sole and exclusive property of the member of the Parent Group designated by Parent, and the Executive will surrender them
upon the termination of the Employment Term, or upon the Company’s request. The Executive will assign to the member of 

  
 10 

 
the Parent Group designated by Parent the Inventions and all patents that may issue thereon in any and all countries, whether during or subsequent to the Employment Term, together with the right
to file, in the Executive’s name or in the name of the member of the Parent Group designated by Parent, applications for patents and equivalent rights (the “Applications”). The Executive will, at any time during and subsequent
to the Employment Term, make such applications, sign such papers, take all rightful oaths, and perform all acts as may be requested from time to time by the Company with respect to the Inventions. The Executive will also execute assignments to the
member of the Parent Group designated by Parent of the Applications, and give the member of the Parent Group designated by Parent and its attorneys all reasonable assistance (including the giving of testimony) to obtain the Inventions for the Parent
Group’s benefit, all without additional compensation to the Executive from the Parent Group. 
 (ii) In addition, the Inventions will
be deemed Work for Hire, as such term is defined under the copyright laws of the United States, on behalf of the Parent Group and the Executive agrees that the member of the Parent Group designated by Parent will be the sole owner of the Inventions,
and all underlying rights therein, in all media now known or hereinafter devised, throughout the universe and in perpetuity without any further obligations to the Executive. If the Inventions, or any portion thereof, are deemed not to be Work for
Hire, the Executive hereby irrevocably conveys, transfers and assigns to the member of the Parent Group designated by Parent, all rights, in all media now known or hereinafter devised, throughout the universe and in perpetuity, in and to the
Inventions, including, without limitation, all of the Executive’s right, title and interest in the copyrights (and all renewals, revivals and extensions thereof) to the Inventions, including, without limitation, all rights of any kind or any
nature now or hereafter recognized, including, without limitation, the unrestricted right to make modifications, adaptations and revisions to the Inventions, to exploit and allow others to exploit the Inventions and all rights to sue at law or in
equity for any infringement, or other unauthorized use or conduct in derogation of the Inventions, known or unknown, prior to the date hereof, including, without limitation, the right to receive all proceeds and damages therefrom. In addition, the
Executive hereby waives any so-called “moral rights” with respect to the Inventions. To the extent that the Executive has any rights in the results and proceeds of the Inventions that cannot be assigned in the manner described herein, the
Executive agrees to unconditionally waive the enforcement of such rights. The Executive hereby waives any and all currently existing and future monetary rights in and to the Inventions and all patents that may issue thereon, including, without
limitation, any rights that would otherwise accrue to the Executive’s benefit by virtue of the Executive being an employee of or other service provider to the Parent Group. 

(e) RETURN OF COMPANY PROPERTY. On the date of the Executive’s termination of employment with the Company for any reason (or at
any time prior thereto at the Company’s request), the Executive shall return all property belonging to the Company or its Affiliates (including, but not limited to, any Company-provided laptops, computers, cell phones, wireless electronic mail
devices or other equipment, or documents and property belonging to the Company). The Executive may retain the Executive’s rolodex and similar address books provided that such items only include contact information. 

(f) REASONABLENESS OF COVENANTS. In signing this Agreement, the Executive gives Parent and the Company assurance that the Executive has
carefully read and 

  
 11 

 
considered all of the terms and conditions of this Agreement, including the restraints imposed under this Section 10. The Executive agrees that these restraints are necessary for the
reasonable and proper protection of the Company and its Affiliates and their trade secrets and confidential information and that each and every one of the restraints is reasonable in respect to subject matter, length of time and geographic area, and
that these restraints, individually or in the aggregate, will not prevent the Executive from obtaining other suitable employment during the period in which the Executive is bound by the restraints. The Executive acknowledges that each of these
covenants has a unique, very substantial and immeasurable value to the Company and its Affiliates and that the Executive has sufficient assets and skills to provide a livelihood while such covenants remain in force. The Executive further covenants
that the Executive will not challenge the reasonableness or enforceability of any of the covenants set forth in this Section 10, other than in response to an attempt by the Company or an Affiliate to enforce such covenants against the
Executive. It is also agreed that the Affiliates will have the right to enforce all of the Executive’s obligations to such Affiliates under this Agreement, including without limitation pursuant to this Section 10. 

(g) REFORMATION. If it is determined by a court of competent jurisdiction in any state that any restriction in this
Section 10 is excessive in duration or scope or is unreasonable or unenforceable under applicable law, it is the intention of the parties that such restriction may be modified or amended by the court to render it enforceable to the
maximum extent permitted by the laws of that state. 
 (h) TOLLING. In the event of any violation of the provisions of this
Section 10, the Executive acknowledges and agrees that the post-termination restrictions contained in this Section 10 shall be extended by a period of time equal to the period of such violation, it being the intention of the
parties hereto that the running of the applicable post-termination restriction period shall be tolled during any period of such violation. 

(i) SURVIVAL OF PROVISIONS. The obligations contained in Sections 10 and 11 hereof shall survive the termination or
expiration of the Employment Term and the Executive’s employment with the Company and shall be fully enforceable thereafter. 
 11.
COOPERATION. Upon the receipt of reasonable notice from the Company (including through outside counsel), the Executive agrees that while employed by the Company and thereafter (to the extent it does not materially interfere with the
Executive’s employment or other business activities after employment by the Company), the Executive will respond and provide information with regard to matters in which the Executive has knowledge as a result of the Executive’s employment
with the Company, and will provide reasonable assistance to the Company, the Affiliates and their respective representatives in defense of all claims that may be made against the Company or the Affiliates, and will assist the Company and the
Affiliates in the prosecution of all claims that may be made by the Company or the Affiliates, to the extent that such claims may relate to the period of the Executive’s employment with the Company. The Executive also agrees to promptly inform
the Company (to the extent that the Executive is legally permitted to do so) if the Executive is asked to assist in any investigation of the Company or the Affiliates (or their actions), regardless of whether a lawsuit or other proceeding has then
been filed against the Company or Affiliates with respect to such investigation, and shall not do so unless legally required. Upon presentation of appropriate documentation, the Company shall pay or reimburse the Executive for all reasonable
out-of-pocket travel, duplicating, telephonic, counsel and other expenses incurred by the Executive in complying with this Section 11. 

  
 12 

 12. EQUITABLE RELIEF AND OTHER REMEDIES. The Executive acknowledges and agrees that the
remedies at law for a breach or threatened breach of any of the provisions of Section 10 hereof or Section 11 hereof would be inadequate and, in recognition of this fact, the Executive agrees that, in the event of such a
breach or threatened breach, in addition to any remedies at law, Parent and/or the Company shall be entitled to obtain equitable relief in the form of specific performance, a temporary restraining order, a temporary or permanent injunction or any
other equitable remedy which may then be available. In the event of a Material Covenant Violation or a Material Cooperation Violation by the Executive, any severance being paid to the Executive pursuant to this Agreement or otherwise shall
immediately cease.  
 13. NO ASSIGNMENTS. This Agreement is personal to each of the parties hereto. Except as provided in
this Section 13 hereof, no party may assign or delegate any rights or obligations hereunder without first obtaining the written consent of the other party hereto. Parent shall assign this Agreement to any successor to all or
substantially all of the business and/or assets of Parent, provided that Parent shall require such successor to expressly assume and agree to perform this Agreement in the same manner and to the same extent that the Company would be required
to perform it if no such succession had taken place. As used in this Agreement, “Parent” shall mean Parent and any successor to all or substantially all of its business and/or assets, which assumes and agrees to perform the duties
and obligations of Parent under this Agreement by operation of law or otherwise. In the event of a sale of the Company (or all or substantially all of its business) to an independent third party in connection with a transaction that does not
constitute a Change in Control, the Company and the Executive shall assign the Company’s rights and obligations hereunder to Parent or to a mutually agreed upon direct or indirect subsidiary of Parent, and the Company shall be released from its
obligations hereunder. 
 14. NOTICES. For purposes of this Agreement, notices and all other communications provided for in this
Agreement shall be in writing and shall be deemed to have been duly given (a) on the date of delivery, if delivered by hand, (b) on the date of transmission, if delivered by confirmed facsimile or electronic mail, (c) on the first

in this Agreement are included solely for convenience and shall not affect, or be used in connection with, the interpretation of this Agreement. In the event of any inconsistency between the terms of this Agreement (including the Exhibits hereto)
and any form, award, plan or policy of the Company, the terms of this Agreement shall govern and control. 
 16. SEVERABILITY. The
provisions of this Agreement shall be deemed severable and the invalidity or unenforceability of any provision shall not affect the validity or enforceability of the other provisions hereof. 

17. COUNTERPARTS. This Agreement may be executed in several counterparts, each of which shall be deemed to be an original but all of
which together will constitute one and the same instrument. 
 18. INDEMNIFICATION. The Company hereby agrees to indemnify the
Executive and hold the Executive harmless to the fullest extent allowable under applicable law against and in respect of any and all actions, suits, proceedings, claims, demands, judgments, costs, expenses (including attorney’s fees, and the
advancement of such fees subject to any legally required repayment undertaking), losses, and damages resulting from the Executive’s performance of the Executive’s duties and obligations with the Company. This obligation shall survive the
termination of the Executive’s employment with the Company. 
 19. LIABILITY INSURANCE. The Company shall cover the Executive
under directors’ and officers’ liability insurance both during and, while potential liability exists, after the Employment Term in the same amount and to the same extent as the Company covers its other officers and directors. 

20. GOVERNING LAW. This Agreement, the rights and obligations of the parties hereto, and any claims or disputes relating thereto, shall
be governed by and construed in accordance with the laws of the State of Delaware (but not including any choice of law rule thereof that would cause the laws of another jurisdiction to apply). 

  
 14 

 21. DISPUTE RESOLUTION. Each of the parties agrees that any dispute between the parties
shall be resolved only in the courts of the State of Delaware or the United States District Court for the District of Delaware and the appellate courts having jurisdiction of appeals in such courts. In that context, and without limiting the
generality of the foregoing, each of the parties hereto irrevocably and unconditionally (a) submits in any proceeding relating to this Agreement or the Executive’s employment by the Company or any Affiliate, or for the recognition and
enforcement of any judgment in respect thereof (a “Proceeding”), to the exclusive jurisdiction of the courts of the State of Delaware, the court of the United States of America for the District of Delaware, and appellate courts
having jurisdiction of appeals from any of the foregoing, and agrees that all claims in respect of any such Proceeding shall be heard and determined in such Delaware State court or, to the extent permitted by law, in such federal court,
(b) consents that any such Proceeding may and shall be brought in such courts and waives any objection that the Executive or the Company may now or thereafter have to the venue or jurisdiction of any such Proceeding in any such court or that
such Proceeding was brought in an inconvenient court and agrees not to plead or claim the same, (c) WAIVES ALL RIGHT TO TRIAL BY JURY IN ANY PROCEEDING (WHETHER BASED ON CONTRACT, TORT OR OTHERWISE) ARISING OUT OF OR RELATING TO THIS AGREEMENT
OR THE EXECUTIVE’S EMPLOYMENT BY THE COMPANY OR ANY AFFILIATE OF THE COMPANY, OR THE EXECUTIVE’S OR THE COMPANY’S PERFORMANCE UNDER, OR THE ENFORCEMENT OF, THIS AGREEMENT, (d) agrees that service of process in any such Proceeding
may be effected by mailing a copy of such process by registered or certified mail (or any substantially similar form of mail), postage prepaid, to such party at the Executive’s or the Company’s address as provided in Section 14
hereof, and (e) agrees that nothing in this Agreement shall affect the right to effect service of process in any other manner permitted by the laws of the State of Delaware. Each party shall be responsible for its own legal fess incurred in
connection with any dispute hereunder. 
 22. MISCELLANEOUS. No provision of this Agreement may be modified, waived or discharged
unless such waiver, modification or discharge is agreed to in writing and signed by the Executive and such officer or director as may be designated by the Board. No waiver by either party hereto at any time of any breach by the other party hereto
of, or compliance with, any condition or provision of this Agreement to be performed by such other party shall be deemed a waiver of similar or dissimilar provisions or conditions at the same or at any prior or subsequent time. This Agreement
together with all exhibits hereto sets forth the entire agreement of the parties hereto in respect of the subject matter contained herein and supersedes any and all prior agreements or understandings between the Executive and the Company with
respect to the subject matter hereof, whether written or oral and, on the Effective Date, supersedes and terminates the Employment Agreement dated as of June 17, 2010 among the parties hereto. No agreements or representations, oral or
otherwise, express or implied, with respect to the subject matter hereof have been made by either party which are not expressly set forth in this Agreement. 

23. REPRESENTATIONS; ACTIONS BY PRIOR EMPLOYERS. The Executive represents and warrants to the Company that (a) the Executive has
used the 

  
 15 

 
Executive’s best efforts to provide the Company with (i) each agreement with a predecessor employer which may have any bearing on the Executive’s legal right to enter into this
Agreement and to perform all of the obligations on the Executive’s part to be performed hereunder in accordance with its terms, or (ii) a summary of the applicable provisions of each such agreement which the Executive may not provide to
the Company due to an existing confidentiality obligation, and (b) other than the agreements referenced in the preceding clause (a), the Executive is not a party to any agreement or understanding, whether written or oral, and is not subject to
any restriction (including, without limitation, any non-competition restriction from a prior employer), which, in either case, could prevent the Executive from entering into this Agreement or performing all of the Executive’s duties and
obligations hereunder. The Executive understands that the foregoing representations are a material inducement to Parent and the Company entering into this Agreement, and to the extent that either of such representations is untrue in any material
respect at any time or for any reason, this Agreement shall be voidable by Parent and the Company such that the parties hereunder shall be relieved of all of their respective duties and obligations hereunder; provided that any termination of
the Executive’s employment resulting from the Company exercising its rights pursuant to this sentence shall be treated as a termination of employment by the Executive without Good Reason. If any prior employer of the Executive, or any affiliate
of any such prior employer, challenges the Executive’s right to enter into this Agreement and to perform all of the Executive’s obligations hereunder (whether by action against the Executive, the Company, Parent and/or an Affiliate), the
Company, Parent (on behalf of itself and all Affiliates) and the Executive each agree to use their reasonable best efforts to defend against such challenge, and the Company further agrees to pay as incurred (within 10 days following the
Company’s receipt of an invoice from the Executive), at any time from the Effective Date through the Executive’s remaining lifetime (or, if longer, through the 20th anniversary of the
Effective Date), all legal fees and expenses that the Executive may reasonably incur as a result of his personal defense of such challenge. 

24. TAX MATTERS. 
 (a)
WITHHOLDING. The Company may withhold from any and all amounts payable under this Agreement or otherwise such federal, state and local taxes as may be required to be withheld pursuant to any applicable law or regulation. 

(b) SECTION 409A COMPLIANCE. 

(i) The intent of the parties is that payments and benefits under this Agreement comply with Section 409A of the Code and the regulations
and guidance promulgated thereunder (collectively “Code Section 409A”) and, accordingly, to the maximum extent permitted, this Agreement shall be interpreted to be in compliance therewith. To the extent that any provision
hereof is modified in order to comply with Code Section 409A, such modification shall be made in good faith and shall, to the maximum extent reasonably possible, maintain the original intent and economic benefit to the Executive and the Company
of the applicable provision without violating the provisions of Code Section 409A. Any such modification shall require the written consent of the Executive. In no event whatsoever shall the Company be liable for any additional tax, interest or
penalty that may be imposed on the Executive by Code Section 409A or damages for failing to comply with Code Section 409A; provided that the Company makes any modification reasonably requested by the Executive in accordance with the
second sentence of this Section 24(b)(i). 

  
 16 

 (ii) A termination of employment shall not be deemed to have occurred for purposes of any
provision of this Agreement providing for the payment of any amounts or benefits upon or following a termination of employment unless such termination is also a “separation from service” within the meaning of Code Section 409A and,
for purposes of any such provision of this Agreement, references to a “termination,” “termination of employment” or like terms shall mean “separation from service.” If the Executive is deemed on the date of termination
to be a “specified employee” within the meaning of that term under Code Section 409A(a)(2)(B), then with regard to any payment or the provision of any benefit that is considered “nonqualified deferred compensation” under
Code Section 409A payable on account of a “separation from service,” such payment or benefit shall be made or provided at the date which is the earlier of (A) the expiration of the six (6)-month period measured from the date of
such “separation from service” of the Executive, and (B) the date of the Executive’s death, to the extent required under Code Section 409A. Upon the expiration of the foregoing delay period, all payments and benefits delayed
pursuant to this Section 24(b)(ii) (whether they would have otherwise been payable in a single sum or in installments in the absence of such delay) shall be paid or reimbursed to the Executive in a lump sum and all remaining payments and
benefits due under this Agreement shall be paid or provided in accordance with the normal payment dates specified for them herein. 
 (iii)
To the extent that reimbursements or other in-kind benefits under this Agreement constitute “nonqualified deferred compensation” for purposes of Code Section 409A, (A) all expenses or other reimbursements hereunder shall be made
on or prior to the last day of the taxable year following the taxable year in which such expenses were incurred by the Executive, (B) any right to reimbursement or in-kind benefits shall not be subject to liquidation or exchange for another
benefit, and (C) no such reimbursement, expenses eligible for reimbursement, or in-kind benefits provided in any taxable year shall in any way affect the expenses eligible for reimbursement, or in-kind benefits to be provided, in any other
taxable year. 
 (iv) For purposes of Code Section 409A, the Executive’s right to receive installment payments pursuant to this
Agreement shall be treated as a right to receive a series of separate and distinct payments. Whenever a payment under this Agreement specifies a payment period with reference to a number of days, the actual date of payment within the specified
period shall be within the sole discretion of the Company. 

  
 17 

 25. FURTHER ASSURANCES; PARENT GUARANTEE. The Company and the Executive shall cooperate
with each other prior to the Closing and do, or procure the doing of, all acts and things, and execute, or procure the execution of, all documents, as may reasonably be required to give full effect to this Agreement (including, without limitation,
the Company taking such actions as are necessary to form Parent under applicable law and cause Parent to execute this Agreement prior to the Closing). Parent hereby guarantees the performance of the obligations of the Company to pay all cash amounts
due to the Executive pursuant to this Agreement. In the event that the Company is unable or unwilling to pay any such amounts when due, upon notice of such non-payment received by Parent from the Executive, Parent shall immediately pay such amounts,
or take any and all actions necessary to cause one or more Affiliates to pay such amounts, on behalf of the Company.

transferee) the number of Vested Securities from the Participating Securityholder which such Participating Securityholder would have been entitled to sell pursuant to Sections 5(b) to 5(d) (inclusive). If the prospective transferee

(ii) raise no objections against, such sale or the process pursuant to which such sale was arranged; (iii) waive any dissenter’s rights, appraisal rights or similar rights to such sale, if such sale is structured as a merger or
consolidation; (iv) vote for and consent to any such Approved Sale; and (v) upon request from the Board or the Bain Investors, transfer a proportionate number of such Executive’s Executive Securities or rights to acquire Securities on
the terms and conditions approved by the Board for all Securities that are the subject of the Approved Sale. Each Executive Securityholder shall take all necessary or desirable actions in connection with the consummation of the Approved Sale as
reasonably requested by the Bain Investors or the Board. If the Bain Investors do not exercise their rights under this Section 6, any Transfer will be subject to Section 5 (Tag Along Rights). 

(b) Distributions upon an Approved Sale. In the event of an Approved Sale, each Executive Securityholder who has been sent an Approved
Sale Notice shall receive in exchange for each Vested Security transferred, the price per Vested Security that the Executive Securityholder would have been entitled to receive in relation his Vested Securities if the aggregate net proceeds received
in the Transfer to which this Section 6 applied were to be paid as a liquidating distribution of the Company in accordance with the terms of this Agreement and the Articles. To the extent any Vested Incentive Securities of the Executive
Securityholder have been transferred as a result of the Executive Securityholder having received an Approved Sale Notice (the “Dragged Vested Incentive Securities”), the Executive Securityholder will be entitled to receive on any
subsequent sale of Bain Securities by one or more Bain Investors any amounts that he would have received had (i) he been holding his Dragged Vested Incentive Securities at the time of any such subsequent sale and (ii) the aggregate net
proceeds received in the subsequent sales been paid as a liquidating distribution of the Company in accordance with the terms of this Agreement and the Articles. 

  
 17 

 (c) Costs. Each Executive Securityholder who sells Executive Securities pursuant to this
Section 6 will bear (out of the proceeds of sale of his Executive Securities) his pro rata share (based on the amount of consideration received by such Executive Securityholder pursuant to such Approved Sale) of the costs incurred
by the Company, the Commandité and/or the Transferring Securityholder in connection with the sale of such Executive Securities to the extent that such costs are incurred for the benefit of all of the holders of the Securities being sold
pursuant to such Approved Sale. 
 (d) All Executives Securityholders who sell Executive Securities pursuant to this Section 6
shall provide the same indemnities, representations and warranties and shall take all actions required under Section 5(f). 

(e) Termination. The provisions of this Section 6 shall terminate upon the termination of the restrictions on Transfer, as
set forth in Section 4(g). 
 7. Public Offering. 

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

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

(ii) If the Board and the managing underwriters agree that it will be more beneficial to either the Bain Investors or the
Public Offering to effect the Public Offering using a Newco or a Subsidiary organized under the laws of a jurisdiction other than Luxembourg, the Company shall form or, if applicable, reorganize or recapitalize such entity, and the holders of
Executive Securities shall, if requested by the Board, contribute all of their Securities to such Newco or Subsidiary in exchange for common stock in Newco or the relevant Subsidiary. 

The Newco Common issued to the holders of Executive Securities shall be allocated among such holders so that, immediately after such exchange, each such
holder of Executive Securities holds 

  
 18 

 
Newco Common having an aggregate value (based on the Public Offering price to the public) equal to the amount which such holder of the Executive Securities would have received if, immediately
prior to such exchange, the Company had distributed to the Securityholders an aggregate amount equal to the Implicit Pre-IPO Value of the Newco Common in a complete liquidation. Shares of Newco Common shall be allocated among such holders as
determined by the rights and preferences set out in the Articles of Association. 
 (c) Cooperation. Subject to the terms and
conditions of this Section 7, each holder of Executive Securities in such Person’s capacity as such, agrees that it shall assist and cooperate with the other holders of Securities and the Board in doing all things necessary, proper
or advisable to consummate and make effective, in the most expeditious manner practicable, any Public Offering and shall otherwise act in a manner conducive to maximizing the aggregate offering proceeds. Each holder of Executive Securities agrees
that if he/she is an Executive on the date of the Public Offering, such Person shall, in his/her capacity as an Executive, provide such representations and warranties as may be reasonably requested by the underwriters, in addition to any
representations and warranties provided by him/her in such Person’s capacity as a Securityholder; provided that such representations and warranties shall be (x) reasonable and customary and (y) consistent with current market
practice at the time of the Public Offering. Subject to the terms and conditions of this Section 7, each of the Company (on behalf of itself, and to the extent applicable, on behalf of Newco and its Subsidiaries) and each holder of
Executive Securities agrees that it shall not take any actions inconsistent with the procedures set out in this Section 7 or that would otherwise undermine the process for a Public Offering undertaken in accordance with this
Section 7. The parties agree that they may carry out or change the form of the reorganization contemplated in Section 7(b) so as to maximize the aggregate tax efficiencies associated with such reorganization, taking into
account the tax position of all the Securityholders; provided that, notwithstanding the foregoing and for the avoidance of doubt, any such reorganization may negatively affect the tax position of individual Securityholders. Furthermore, the
parties agree that, in the event that any prospective Public Offering is not consummated, and the Board shall so elect, they will assist and cooperate with the other holders of Securities and the Board in doing all things necessary to reverse as
expeditiously as reasonably practicable any reorganization of the Company and its Subsidiaries and, to the extent reasonably practicable, to return the Company and Subsidiaries to their corporate forms and capitalization prior to any reorganization
or recapitalization. 
 (d) Waiver. Without limiting the generality of the foregoing, each holder of Executive Securities hereby
waives any dissenter’s rights, appraisal rights or similar rights in connection with any recapitalization, reorganization and/or exchange pursuant to this Section 7. 

(e) Registration Rights. In the event that the Bain Investors become entitled to any registration rights in connection with any Public
Sale, the Executive Securityholders shall, solely with respect to their Vested Securities and only to the extent consistent with applicable law, have the right to participate in such Public Sale on a pro rata basis with the Bain Investors
participating therein (such Executive Securityholder’s “Participating Percentage”), subject to reasonable cutbacks determined by the managing underwriters and the Registration Rights Agreement; provided that, to the
extent an Executive Securityholder did not have enough Vested Securities to be able to sell his full Participating Percentage at the time of the original sale, such Executive Securityholder shall (subject to reasonable cutbacks determined by the
managing 

  
 19 

 
underwriter) be entitled to participate on the next secondary offering also with such number of Vested Securities equal to the difference between the Executive Securityholder’s Participating
Percentage and the number of Vested Securities sold by such Executive Securityholder in the original sale (including any Vested Securities that were cutback from the original sale as determined by the managing underwriters). Each Executive
Securityholder who elects to participate in a Public Sale pursuant to this Section 7(e) shall enter into a Registration Rights Agreement. 

8. “Material Covenant Violation” or a “Material Cooperation Violation.” In the event of a Material Covenant
Violation or a Material Cooperation Violation (each, as defined in the Employment Agreement), (i) any Incentive Securities which have not at the time of such Material Covenant Violation or a Material Cooperation Violation (the “MCV
Date”) become Vested Securities and (ii) any Incentive Securities that became Vested Securities in the preceding 6-month period ((i) and (ii) together, the “MCV Securities”) may be purchased by the Company or the
Bain Investors or such other Person as the Bain Investors may identify, at the lower of Fair Market Value and their Original Cost in accordance with the procedures set forth below in Section 9(b)(iv). 

9. Right to Purchase the Incentive Securities. 

(a) Call Option - Non-Achievement of Performance Threshold. In the event that the Performance Vesting Incentive Securities do
not become Vested Securities as a result of the Performance Threshold not being achieved upon a Change in Control or Public Offering in accordance with Section 2(f), such Performance Vesting Incentive Securities may be purchased
by the Company or the Bain Investors or such other Person as the Bain Investors may identify, at the lower of Fair Market Value and their Original Cost in accordance with the procedure set forth in Section 9(b)(iv). 

(b) Call Option. In the event the Executive ceases to be employed by the Company or any of its Subsidiaries, the Incentive Securities
then held by the Executive (or his Permitted Transferees, as applicable) may be purchased by the Company or the Bain Investors or such other Person as the Bain Investors may identify, in accordance with the procedure set forth in
Section 9(b)(iv) (the “Call Option”). 
 (i) Good Leaver. If the Executive is a Good
Leaver, then at any time on or after the Executive’s Termination Date, the Company or the Bain Investors, as applicable, may purchase all or any portion of the Incentive Securities which are Vested Securities at Fair Market Value and, subject
to the proviso below in this Section 9(b)(i), the entire portion of the Incentive Securities which are Unvested Securities at the lower of their Fair Market Value and their Original Cost in accordance with the procedures set forth in
Section 9(b)(iv), provided that, the Executive (or any of his Permitted Transferees, if applicable) shall be permitted for a period of 12 months from the Executive’s Termination Date (the “Post Termination
Period”) to retain any of the Unvested Performance Vesting Incentive Securities (the “Unvested Post-Termination Securities”). If during the Post Termination Period, the Performance Threshold is achieved in connection with a
Change in Control or Public Offering, the Unvested Post-Termination Securities shall become Vested Securities (and shall, for the avoidance of 

  
 20 

 
doubt, be treated as Vested Securities for all purposes of this Agreement). If, however, the Performance Threshold is not achieved during the Post Termination Period, after the expiration of such
period, the Unvested Post-Termination Securities shall no longer be capable of vesting and may be purchased at the lower of their Fair Market Value and their Original Cost in accordance with the procedures set forth in Section 9(b)(iv).

 (ii) Medium Leaver. If an Executive’s Termination is the result of the Executive’s voluntary resignation
without Good Reason, then on or after the Executive’s Termination Date, the Company or the Bain Investors, as applicable, may purchase (a) all or any portion of the Incentive Securities which are Vested Securities at Fair Market Value
(provided, that, if Executive provides the Company with less than one years’ notice prior to Executive’s intended effective date of his voluntary resignation without Good Reason, then, notwithstanding the foregoing, on or after the
Executive’s Termination Date, the Company or the Bain Investors, as applicable, may purchase all or any portion of the Incentive Securities which are both New Securities and Vested Securities at the lower of their Fair Market Value and their
Original Cost and the portion (if any) of the balance of the Catch up Amount attributable to the Executive’s vested New Securities (and any vested Incentive Securities of any Permitted Transferee thereof) shall be forfeited and retained by the
Company) and (b) the entire portion of the Incentive Securities which are Unvested Securities at the lower of their Fair Market Value and their Original Cost, in each case in accordance with the procedures set forth below; provided,
that, in the case of this Section 9(b)(ii), the Company’s election to accelerate the Executive’s Termination Date shall not be considered a Termination by the Company without Cause or constitute Good Reason hereunder and,
accordingly, shall not entitle the Executive Securityholders to any vesting pursuant to clause (I) of the final paragraph of Section 2(e). 

(iii) Bad Leaver. If the Executive’s Termination is the result of the Executive’s Termination by the Company
or one of its Subsidiaries occurring for Cause, then on or after the Executive’s Termination Date, the Company or the Bain Investors, as applicable, may purchase all of the Incentive Securities (including both Vested Securities and Unvested
Securities) at the lower of Fair Market Value and their Original Cost in accordance with the procedures set forth below and the portion (if any) of the balance of the Catch up Amount attributable to the Executive’s vested Incentive Securities
(and any vested Incentive Securities of any Permitted Transferee thereof) shall be forfeited and retained by the Company. 

(iv) Call Option Exercise Procedures. At the Board’s discretion, the Company or the Bain Investors or such other
Person as the Bain Investors may identify, as applicable, may purchase and, except as otherwise provided below, the Executive Securityholders shall sell all or any portion of the Incentive Securities held by the Executive Securityholders, upon
delivery, by the Company or the Bain Investors, as applicable, of a written notice (the “Call Option Exercise Notice”) to such Executive Securityholders (i) subject to clauses (ii), (iii) and (iv) below, during the
180-day period following the Executive’s Termination Date, (ii) with respect to Unvested Post-Termination Securities during the 180-day period commencing on the earlier of the date such Securities vest and the expiration of the Post
Termination Period, (iii) with respect 

  
 21 

 
to any Performance Vesting Incentive Securities which have not become Vested Securities under Section 2(f), within 180 days following a Change in Control or Public Offering or
(iv) with respect to the MCV Securities, during the 180-day period commencing on the MCV Date (each of the foregoing periods collectively, the “Call Option Exercise Period”). The Company may at any time during the Call Option
Exercise Period assign its right to exercise the Call Option to the Bain Investors. The Call Option Exercise Notice will set forth the amount of such Incentive Securities to be acquired, the aggregate consideration to be paid for such Incentive
Securities, the Board’s determination of Fair Market Value in accordance with Section 10(a) (if any Incentive Securities are to be purchased for a price equal to Fair Market Value) and the time and place for the anticipated closing
of the transaction. If any of the Incentive Securities is held by Permitted Transferees, the Company or the Bain Investors, as applicable, shall purchase the Incentive Securities from such holder(s) pro rata according to the number of Incentive
Securities held by such holder(s) at the time of delivery of such Call Option Exercise Notice (determined as nearly as practicable to the nearest Ordinary Share). 

(v) Assignment Rights. If any of the Company or any Bain Investor (or its respective assignee) shall have elected to
exercise its respective Call Option to purchase Incentive Securities, then at any time prior to the closing of such transaction, any of the Company or any Bain Investor (or its respective assignees) may resell such of the Incentive Securities as
have been purchased, or assign the right to buy such Incentive Securities as would have been purchased, to any employee of the Company or its subsidiaries or any other designee in such amount(s) as the Board or such Bain Investor, as the case may
be, shall determine in its respective full discretion and such employee or designee shall have agreed to purchase. Such offer shall be effective with respect to all or any portion of the Call Option. 

(vi) Closing. The closing of the transactions contemplated by this Section 9(b) will take place on the date
designated by the Company or the Bain Investors and in any event no later than the later of (a) the end of the Call Option Exercise Period and (b) the 10th day following the determination of Fair Market Value in accordance with
Section 10. The Bain Investors and/or the Company, as the case may be, will pay for the Incentive Securities to be purchased pursuant to the Call Option by wire transfer of immediately available funds to the holder of such Incentive
Securities, in the aggregate amount equal to the purchase price for such Incentive Securities. The Bain Investors and/or the Company, as the case may be, shall receive from each seller regarding the sale of the Incentive Securities to the relevant
purchaser, representations and warranties that such seller has good and marketable title to the Incentive Securities to be transferred, free and clear of all liens, claims and other encumbrances and that such seller can validly enter into and be
bound by the agreement of sale together with such other representations and warranties as may be reasonable and customary at the time of sale. If the Company elects to purchase any Incentive Securities subject to the Call Option (that are not to be
resold or for which such purchase rights are not assigned pursuant to Section 9(b)(v)), the Incentive Securities so acquired by the Company shall be redeemed in accordance with the provisions of Article 49-8 of the law of 10 August
1915 on commercial companies, as amended. 
 (vii) Termination of Repurchase Right. The Call Option, and the
associated rights of the Calling Person to purchase Executive Securities pursuant to Section 9(b) shall terminate upon the completion of a Public Sale or a Sale of the Company. 

  
 22 

 10. Fair Market Value. 

(a) The Fair Market Value of Incentive Securities subject to the Call Right shall be determined by the Board in its good faith discretion and,
to the extent any Incentive Securities are to be purchased for a price equal to Fair Market Value, included in the Call Option Exercise Notice, but shall be subject to adjustment in accordance with this Section 10. 

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

(c) Within 30 days starting on the day after receipt of the Call Option Exercise Notice, the Executive shall notify the Board in writing if
the Executive does not agree with the Board’s calculation of Fair Market Value (a “Disagreement Notice”). 
 (d) If
the Executive does not provide the Board with a Disagreement Notice within the 30-day period referred to in Section 10(c), the calculation of the Fair Market Value provided by the Board shall be final and binding and shall constitute the
Fair Market Value. If the Executive provides the Board with a Disagreement Notice within the 30-day period referred to in Section 10(c), the Executive may appoint a nationally recognized firm experienced in the valuation of private
companies to determine the Fair Market Value (the “Executive Valuator”). The Company shall promptly provide all data reasonably requested by the Executive Valuator (including but not limited to financial data) which the Executive
Valuator determines in good faith is necessary in order for it to determine Fair Market Value. 
 (e) If, within 60 days starting on the day
after receipt of the Disagreement Notice (or such longer period as may be agreed by the Executive and the Board), the Executive (being advised by the Executive Valuator) and the Board have not agreed to the Fair Market Value, the Executive and the
Board shall refer the matters in dispute to a nationally recognized independent firm of accountants agreed by the parties in writing. If the Executive and the Board are unable to agree on the appointment of an independent firm of accountants after a
further 21 days, an independent firm of accountants will be appointed on the application of either party to the President at that time of the American Institute of Certified Public Accountants (the “Independent Valuator”) for the
purposes of determining the Fair Market Value which shall be either the number originally included in the Call Option Exercise Notice or the number submitted by the Executive to the Independent Valuator. 

(f) If the final Fair Market Value, as determined pursuant to the process described above, is 110% or more of the Fair Market Value originally
determined by the Board and included in the Call Option Exercise Notice, then the Company will pay the cost of the Executive Valuator and, if applicable, the Independent Valuator, and if such final Fair Market Value is less than 110% of the Fair
Market Value originally determined by the Board, then the Executive will pay the cost of the Executive Valuator and, if applicable, the Independent 

  
 23 

 
Valuator. Notwithstanding the above, in choosing the Independent Valuator, if applicable, the Board and the Executive shall take into account the cost thereof, with a view of retaining a firm
which charges not more than $200,000 for such valuation. 
 11. Preemptive Rights. 

(a) Each Executive Securityholder irrevocably and unconditionally waives to the fullest extent any and every pre-emptive right, present or
future, that he/she/it may have in respect of any issuance of shares by the Company (droit de souscription préférentiel) for the whole period during which the Executive Securityholder is a shareholder of the Company. By signing
this Agreement, the Executive Securityholder grants an irrevocable power of attorney (procuration) to the Commandité to take any action, including for the avoidance of doubt, the signing of any notarial deed in the name and on behalf
of the Executive Securityholder to waive his/her/its pre-emptive right in respect of a particular issuance of shares by the Company (droit de souscription préférentiel). Such power of attorney includes the right for the
Commandité to sign in the name and on behalf of the Executive Securityholder one or several powers of attorney (procurations) to represent the Executive Securityholder at any shareholders’ meeting of the Company to formally waive
any such pre-emptive right. 
 (b) Notwithstanding Section 11(a), in the event that an Executive Securityholder becomes entitled
to purchase Securities in connection with an issuance of Securities to other persons and the Bain Investors determine in good faith that it is in the best interest of the Company or its Subsidiaries that such an issuance be conducted on an
accelerated basis (relative to the time periods otherwise afforded to such Executive Securityholder to elect to exercise such rights or fund such purchase) due to cash or liquidity requirements (including, but not limited to, a prospective breach of
a liquidity covenant) (an “Emergency Equity Offering”), then such issuance may be completed prior to the expiration of such time periods; provided that the purchaser(s) of the Equity Securities offered pursuant to the
Emergency Equity Offering shall: 
 (i) be required promptly, and in any event not later than ten (10) days after the
date of completion of such Emergency Equity Offering, to offer to sell to the Executive Securityholders such Securities as such holders would have been entitled to subscribe for had such issuance been effected within the otherwise applicable time
periods at the price and on the other terms thereof; and 
 (ii) not vote such Equity Securities prior to completion of the
sales, if any, to the Executive Securityholders pursuant to this Section 11(b). 
 (c) In the event any of the transactions set
forth in Section 5 (Tag Along) or Section 6 (Drag-Along Right) occur after the date of completion of an Emergency Equity Offering and prior to the issuance of Equity Securities pursuant to an Executive Securityholder
exercising its rights under Section 11(b), the Equity Securities to be issued to such Executive Securityholder under Section 11(b) shall be included for the purpose of determining the number of Executive Securities to be
transferred in a Transfer pursuant to Section 5 (Tag Along) or Section 6 (Drag-Along Right), as applicable. 

  
 24 

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

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

13. 83(b) Election. The Executive will make an election pursuant to Section 83(b) of the U.S. Internal Revenue Code in respect of
the Incentive Securities within 30 days following the issuance thereof to the Executive. The Incentive Securities are intended to constitute, and shall be treated for all purposes, as “profits interests” within the meaning of Revenue
Procedures 93-27 and 2001-43 and any other official guidance promulgated thereafter. 
 14. Amendment and Waiver. Subject to
Section 15, the provisions of this Agreement may be amended, modified or waived only with the prior written consent of the Company, holders of a majority of the Executive Securities and holders of a majority of the Bain Securities. No
course of dealing or the failure of any party to enforce any of the provisions of this Agreement shall in any way operate as a waiver of such provisions or affect the right of such party thereafter to enforce each and every provision of this
Agreement in accordance with its terms. The provisions of this Section 14 shall remain unaffected by any amendment, modification or waiver of this Agreement. 

  
 25 

 15. Severability. Whenever possible, each provision of this Agreement shall be interpreted
in such manner as to be effective and valid under applicable law, but if any provision of this Agreement is held to be invalid, illegal or unenforceable in any respect under any applicable law or rule in any jurisdiction, such invalidity, illegality
or unenforceability shall not affect the validity, legality or enforceability of any other provision of this Agreement in such jurisdiction or affect the validity, legality or enforceability of any provision in any other jurisdiction, but this
Agreement shall be reformed, construed and enforced in such jurisdiction as if such invalid, illegal or unenforceable provision had never been contained herein. 

16. Entire Agreement. Except as otherwise expressly set forth herein, this Agreement and the documents referred to herein embody the
complete agreement and understanding among the parties hereto with respect to the subject matter hereof and supersede and pre-empt any prior understandings, agreements or representations by or among the parties, written or oral, which may have
related to the subject matter hereof in any way. 
 17. Successors and Assigns. Except as otherwise provided herein, this Agreement
shall bind and inure to the benefit of and be enforceable by the Company and the Commandité and their respective permitted successors and assigns, the holders of Executive Securities and the respective permitted successors and assigns of each
of them, so long as they hold Executive Securities, and the holders of Bain Securities and the respective permitted successors and assigns of each of them, so long as they hold Bain Securities. 

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

20. Notices. All notices, demands or other communications to be given or delivered under or by reason of the provisions of this
Agreement shall be in writing and shall be deemed to have been received (a) when delivered personally to the recipient, (b) when telecopied to the recipient (with hard copy sent to the recipient by internationally reputable overnight
courier service (charges prepaid) that same day) if telecopied before 5:00 p.m., local time in the jurisdiction of recipient on a Business Day, and otherwise on the next Business Day, or (c) two Business Days after being sent to the recipient
by internationally reputable overnight courier service (charges prepaid). Such notices, demands and other communications shall be sent to the

 BAIN CAPITAL EVEREST MANAGER HOLDING S.C.A. 

9A, Rue Gabriel Lippmann 

L-5365 Munsbach 
 Grand
Duchy of Luxembourg 
 April 18, 2013 

Mr. Christopher Pappas 
 615 East Drive 

Sewickley, PA 15143 
 U.S.A. 

Dear Mr. Pappas: 
 Reference is made to the
Subscription and Securityholder’s Agreement (the “Agreement”) dated April 18, 2013 by and among you and Bain Capital Everest Manager Holding S.C.A. (the “Company”), Bain Capital Everest Manager, and
certain other Bain Investors (as defined in the Agreement). Capitalized terms used but not otherwise defined herein shall have the meanings given to such terms in the Agreement. 

You subscribed for and purchased (i) 14,525 shares of the Company’s Class H Ordinary Shares, (ii) 14,524 shares of the
Company’s Class I Ordinary Shares, (iii) 14,523 shares of the Company’s Class J Ordinary Shares, (iv) 14,523 shares of the Company’s Class K Ordinary Shares, and (v) 14,523 shares of the Company’s Class L Ordinary
Shares (collectively, the “Shares”) on April 18, 2013. 
 As of the date hereof, the Company believes that the net
liquidation value of the Company currently does not exceed $615,694,000 (the “Company Value”). This letter is entered into in order to ensure that your Shares do not represent an interest in such existing liquidation value, but
rather represents only an interest in future appreciation, and hence is a “profits” interest within the meaning of IRS Revenue Procedure 93-27. The sum of (i) the Company Value plus (ii) the amount of the Company Value that would
be received by the recipients of the Shares if the Company were liquidated immediately after the date hereof and the net liquidation proceeds distributed, shall be referenced herein as the “Target Value.” 

Upon execution of this letter, you hereby agree that upon any liquidation or dissolution of the Company, if the aggregate amount distributed
or received after the subscription of the Shares in respect of all outstanding equity interests in the Company (the “Received Value”) is (i) less than the Company Value, then you shall pay the Company 100% of the amount you
have received in respect of the Shares or (ii) greater than the Company Value but less than the Target Value, then you shall pay the Company an amount equal to the Applicable Percentage of the amount you have received in respect of the Shares;
provided that your payment to the Company shall not exceed the lesser of (A) 100% of the net amount of proceeds received by you on account of your Shares and (B) the amount of the Company Value that would be received by you as a
result of the subscription of the Shares in respect of your Shares if the Company were liquidated immediately after the subscription of the Shares and the net liquidation 

 
proceeds distributed (the “Equity Shortfall”). The “Applicable Percentage” means the percentage determined by dividing the excess of the Target Value over the
Received Value by the excess of the Target Value over the Company Value. Notwithstanding the preceding sentence, if one or more other persons is subject to a give-back agreement similar to this agreement, equity proceeds received by such other
persons with respect to the portion of their interest subject to the give-back agreement shall be disregarded in determining the Equity Shortfall to such extent the Company determines is necessary to cause your interest in the Shares to constitute a
“profits” interest within the meaning of IRS Revenue Procedure 93-27. 
 In addition to the foregoing, you hereby agree that any
successor or assign of your Shares, or any portion thereof, shall be bound by and have all the obligations that you have with respect to such Shares.

 EXHIBIT C 

SECTION 280G PROVISIONS 

This Exhibit C sets forth the terms and provisions applicable to the Executive pursuant to the provisions of Section 8 of the Agreement.
This Exhibit C shall be subject in all respects to the terms and conditions of the Agreement. Capitalized terms used without definition in this Exhibit C shall have the meanings set forth in the Agreement. 

 

	1.	Change in Control Prior to Publicly Traded Equity of Company. So long as the Company is described in Section 280G(b)(5)(A)(ii)(I) of the Code, in the event that any payment that is either received by the
Executive or paid by the Company on the Executive’s behalf or any property, or any other benefit provided to the Executive under the Agreement or under any other plan, arrangement or agreement with the Company or any other person whose payments
or benefits are treated as contingent on a change of ownership or control of the Company (or in the ownership of a substantial portion of the assets of the Company) or any person affiliated with the Company or such person (but only if such payment
or other benefit is in connection with the Executive’s employment by the Company) (collectively the “Company Payments”), would be subject to the tax imposed by Section 4999 of the Code (and any similar tax that may
hereafter be imposed by any taxing authority) (the “Excise Tax”), the Company shall, with respect to such Company Payments, use its reasonable best efforts to obtain a vote satisfying the requirements of Section 280G(b)(5) of
the Code, such that no portion of the Company Payments will be subject to such Excise Tax. In the event that a vote satisfying the requirements of Section 280G(b)(5) of the Code is not obtained for any reason, then the Executive will be
entitled to receive a portion of the Company Payments having a value equal to $1 less than three (3) times the Executive’s “base amount” (as such term is defined in Section 280G(b)(3)(A) of the Code). Any reduction of the
Company Payments pursuant to the foregoing shall occur in the following order: (i) any cash severance payable by reference to the Executive’s base salary or annual bonus; (ii) any other cash amount payable to the Executive;
(iii) any benefit valued as a “parachute payment;” and (iv) acceleration of vesting of any equity award. 

  

	2.	Change in Control Upon or Following Publicly Traded Equity of Company. In the event that Company Payments become payable to the Executive during any period in which the Company is not described in
Section 280G(b)(5)(A)(ii)(I) of the Code, the following shall apply: 

  

	 	(a)	In the event that such Company Payments will be subject to the Excise Tax, the Company shall pay to the Executive an additional amount (the “Gross-Up Payment”) such that the net amount retained by the
Executive, after deduction of any Excise Tax on the Company Payments and any U.S. federal, state, and local income or payroll tax upon the Gross-Up Payment provided for by this clause 2(a), but before deduction for any U.S. federal, state, and local
income or payroll tax on the Company Payments, shall be equal to the Company Payments. 

  
 C-1 

	 	(b)	For purposes of determining whether any of the Company Payments and Gross-Up Payment (collectively, the “Total Payments”) will be subject to the Excise Tax and the amount of such Excise Tax,
(i) the Total Payments shall be treated as “parachute payments” within the meaning of Section 280G(b)(2) of the Code, and all “parachute payments” in excess of the “base amount” (as defined under
Section 280G(b)(3) of the Code) shall be treated as subject to the Excise Tax, unless and except to the extent that, in the opinion of the Company’s independent certified public accountants appointed prior to any change in ownership (as
defined under Section 280G(b)(2) of the Code) or tax counsel selected by such accountants or the Company (the “Accountants”) such Total Payments (in whole or in part) are not subject to the Excise Tax, and (ii) the value
of any non-cash benefits or any deferred payment or benefit shall be determined by the Accountants in accordance with the principles of Section 280G of the Code. In the event that the Accountants are serving as accountants or auditors for the
individual, entity or group effecting the change in control (within the meaning of Section 280G of the Code), the Company shall appoint another nationally recognized accounting firm to make the determinations hereunder (which accounting firm
shall then be referred to as the “Accountants” hereunder). All determinations hereunder shall be made by the Accountants, who shall provide detailed supporting calculations both to the Company and the Executive at such time as it is
requested by the Company or the Executive. The determination of the Accountants shall be final and binding upon the Company and the Executive. 

  

	 	(c)	For purposes of determining the amount of the Gross-Up Payment, the Executive’s marginal blended actual rates of federal, state and local income taxation in the calendar year in which the change in ownership or
effective control that subjects the Executive to the Excise Tax occurs shall be used. In the event that the Excise Tax is subsequently determined by the Accountants to be less than the amount taken into account hereunder at the time the Gross-Up
Payment is made, the Executive shall promptly repay to the Company, at the time that the amount of such reduction in Excise Tax is finally determined, the portion of the prior Gross-Up Payment attributable to such reduction (plus the portion of the
Gross-Up Payment attributable to the Excise Tax and U.S. federal, state and local income tax imposed on the portion of the Gross-Up Payment being repaid by the Executive), plus interest on the amount of such repayment at the rate provided in
Section 1274(b)(2)(B) of the Code. In the event that the Excise Tax is later determined by the Accountants or the Internal Revenue Service to exceed the amount taken into account hereunder at the time the Gross-Up Payment is made (including by
reason of any payment the existence or amount of which cannot be determined at the time of the Gross-Up Payment), the Company shall make an additional Gross-Up Payment in respect of such excess (plus any interest or penalties payable with respect to
such excess imposed by the applicable taxing authority) promptly after the amount of such excess is finally determined. 

  

	 	(d)	 The Gross-Up Payment or portion thereof provided for in clause 2(c) above shall be paid not later than the sixtieth (60th) day following an event
occurring which subjects the Executive to the Excise Tax; provided, however, that if the amount of 

  
 C-2 

	 	
such Gross-Up Payment or portion thereof cannot be finally determined on or before such day, the Company shall pay to the Executive on such day an estimate, as determined in good faith by the
Accountants, of the minimum amount of such payments and shall pay the remainder of such payments (together with interest at the rate provided in Section 1274(b)(2)(B) of the Code), subject to further payments pursuant to clause 2(c) above, as
soon as the amount thereof can reasonably be determined. Subject to clauses 2(c) and 2(h) of this Exhibit C, in the event that the amount of the estimated payments exceeds the amount subsequently determined to have been due, such excess shall
constitute a loan by the Company to the Executive, payable on the fifth (5th) day after demand by the Company (together with interest at the rate provided in Section 1274(b)(2)(B) of the Code). 

 

	 	(e)	The Executive shall promptly notify the Company in writing of any claim by any taxing authority that, if successful, would require the payment by the Company of a Gross-Up Payment; provided, however, that
failure by the Executive to give such notice promptly shall not result in a waiver or forfeiture of any of the Executive’s rights under this Exhibit C except to the extent of actual damages suffered by the Company as a result of such failure.
If the Company notifies the Executive in writing within 15 days after receiving such notice that it desires to contest such claim (and demonstrates to the reasonable satisfaction of the Executive its ability to pay any resulting Gross-Up Payment),
the Executive shall: 

  

	 	(i)	give the Company any information reasonably requested by the Company relating to such claim; 

  

	 	(ii)	take such action in connection with contesting such claim as the Company shall reasonably request in writing from time to time, including, without limitation, accepting legal representation with respect to such claim by
an attorney selected by the Company that is reasonably acceptable to the Executive; 

  

	 	(iii)	cooperate with the Company in good faith in order effectively to contest such claim; and 

  

	 	(iv)	permit the Company to participate in any proceedings relating to such claim; 

 provided,
however, that the Company’s actions do not unreasonably interfere with or prejudice Executive’s disputes with the taxing authority as to other issues; and provided, further, that the Company shall bear and pay on an
after-tax and as-incurred basis, all attorneys fees, costs and expenses (including additional interest, penalties and additions to tax) incurred in connection with such contest (including but not limited to those of the Executive’s personal
counsel) and shall indemnify and hold the Executive harmless, on an after-tax and as-incurred basis, for all resulting taxes (including, without limitation, income and excise taxes), interest, penalties and additions to tax. 

  
 C-3 

	 	(f)	The Company shall be responsible for all charges of the Accountants. 

  

	 	(g)	The Company and the Executive shall promptly deliver to each other copies of any written communications, and summaries of any verbal communications, with any taxing authority regarding the Excise Tax covered by this
Exhibit C. 

  

	 	(h)	Nothing in this Exhibit C is intended to violate the Sarbanes-Oxley Act of 2002 and to the extent that any advance or repayment obligation hereunder would do so, such obligation shall be modified so as to make the
advance a nonrefundable payment to the Executive and the repayment obligation null and void. 

  

	 	(i)	Notwithstanding the foregoing, any payment or reimbursement made pursuant to this clause 2 shall be paid to the Executive promptly and in no event later than the end of the calendar year next following the calendar year
in which the related tax is paid by the Executive or as otherwise provided under Treasury Regulation §1.409A-3(i)(1)(v). 

  

	3.	The provisions of this Exhibit C shall survive the termination of the Executive’s employment with the Company for any reason and any amount payable under this Exhibit C shall be subject to the provisions of
Sections 8(e) and 24 of the Agreement.

Release and do not revoke this General Release within the time period permitted hereafter. Such payments and benefits will not be considered compensation for purposes of any employee benefit plan, program, policy or arrangement maintained or
hereafter established by the Company or its affiliates. 
 2. Except as provided in paragraphs 4 and 5 below and except for the provisions of the Agreement
which expressly survive the termination of my employment with the Company, I knowingly and voluntarily (for myself, my heirs, executors, administrators and assigns) release and forever discharge the Company and the other Released Parties from any
and all claims, suits, controversies, actions, causes of action, cross-claims, counter-claims, demands, debts, compensatory damages, liquidated damages, punitive or exemplary damages, other damages, claims for costs and attorneys’ fees, or
liabilities of any nature whatsoever in law and in equity, both past and present (through the date this General Release becomes effective and enforceable) and whether known or unknown, suspected, or claimed against the Company or any of the Released
Parties which I, my spouse, or any of my heirs, executors, administrators or assigns, may have, which arise out of or are connected with my employment with, or my separation or termination from, the Company (including, but not limited to, any

Company; or any claim for wrongful discharge, breach of contract, infliction of emotional distress, defamation; or any claim for costs, fees, or other expenses, including attorneys’ fees
incurred in these matters) (all of the foregoing collectively referred to herein as the “Claims”). 
 3. I represent that I have made no
assignment or transfer of any right, claim, demand, cause of action, or other matter covered by paragraph 2 above.

does not waive or release any rights or claims that I may have under the Age Discrimination in Employment Act of 1967 which arise after the date I execute this General Release. I acknowledge and agree that my separation from employment with the
Company in compliance with the terms of the Agreement shall not serve as the basis for any claim or action (including, without limitation, any claim under the Age Discrimination in Employment Act of 1967). 

5. I agree that I hereby waive all rights to sue or obtain equitable, remedial or punitive relief from any or all Released Parties of any kind whatsoever in
respect of any Claim, including, without limitation, reinstatement, back pay, front pay, and any form of injunctive relief. Notwithstanding the above, I further acknowledge that I am not waiving and am not being required to waive any right that
cannot be waived under law, including the right to file an administrative charge or participate in an administrative investigation or proceeding; provided, however, that I disclaim and waive any right to share or participate in any monetary award
resulting from the prosecution of such charge or investigation or proceeding. Additionally, I am not waiving any right to the Accrued Benefits or claims for indemnity or contribution. 

6. In signing this General Release, I acknowledge and intend that it shall be effective as a bar to each and every one of the Claims hereinabove mentioned or
implied. I expressly consent that this General Release shall be given full force and effect according to each and all of its express terms and provisions, including those relating to unknown and unsuspected Claims (notwithstanding any state or local
statute that expressly limits the effectiveness of a general release of unknown, unsuspected and unanticipated Claims), if any, as well as those relating to any other Claims hereinabove mentioned or implied. I acknowledge and agree that this waiver
is an essential and material term of this General Release and that without such waiver the Company would not have agreed to the terms of the Agreement. I further agree that in the event I should bring a Claim seeking damages against the Company, or
in the event I should seek to recover against the Company in any Claim brought by a governmental agency on my behalf, this General Release shall serve as a complete defense to such Claims to the maximum extent permitted by law. I further agree that
I am not aware of any pending claim of the type described in paragraph 2 as of the execution of this General Release. 
 7. I agree that neither this
General Release, nor the furnishing of the consideration for this General Release, shall be deemed or construed at any time to be an admission by the Company, any Released Party or myself of any improper or unlawful conduct. 

8. I agree that if I violate this General Release by suing the Company or the other Released Parties, I will pay all costs and expenses of defending against
the suit incurred by the Released Parties, including reasonable attorneys’ fees.

not to disclose the same to anyone. The Company agrees to disclose any such information only to any tax, legal or other counsel of the Company as required by law.

this General Release.

acknowledge that I may hereafter discover claims or facts in addition to or different than those which I now know or believe to exist with respect to the subject matter of the release set forth in paragraph 2 above and which, if known or suspected
at the time of entering into this General Release, may have materially affected this General Release and my decision to enter into it.

(the “Company”), Bain Capital Everest Manager Holding SCA, a Luxembourg incorporated company (“Parent”) and Curtis S. Shaw (the “Executive”). 

W I T N E S S E T H 

WHEREAS, the Company desires to employ the Executive as the Executive Vice President & General Counsel of the Company and
to pay all of the Executive’s compensation other than certain equity awards described in this Agreement; and 

WHEREAS, Parent desires the Executive to be its Executive Vice President & General Counsel, to grant the Executive
certain equity awards described in this Agreement and to guarantee the cash compensation of the Executive payable by the Company hereunder; and 
 WHEREAS, the Company, Parent and the Executive desire to enter into this Agreement as to the terms of the Executive’s employment with the Company. 

NOW, THEREFORE, in consideration of the foregoing, of the mutual promises contained herein and of other good and valuable
consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto hereby agree as follows: 

1. POSITION AND DUTIES. 
 (a) During the Employment Term (as defined in Section 2 hereof), the Executive shall serve as the Executive Vice President & General Counsel of the Company and Parent. In this
capacity, the Executive shall have the duties, authorities and responsibilities commensurate with the duties, authorities and responsibilities of persons in similar capacities in similarly sized companies, and such other executive duties,
authorities and responsibilities as may reasonably be assigned to the Executive that are not inconsistent with the Executive’s position as Executive Vice President & General Counsel of the Company. The Executive’s principal place
of employment with the Company shall be in either Pittsburgh or Philadelphia, Pennsylvania, to be determined in the Company’s sole discretion following the date hereof (such city as chosen by the Company, the “Headquarters
City”); provided that (i) the Executive understands and agrees that the Executive will be required to travel frequently for business purposes and (ii) the Executive and the Company agree that Executive shall continue to
maintain his residence and domicile in Dallas, Texas through the end of calendar year 2010. The Executive shall report directly to the Company’s Chief Executive Officer. Executive will relocate his primary residence to the Headquarters City
metropolitan area as soon as reasonably practicable following the end of calendar year 2010. 
 (b) During the Employment Term,
the Executive shall devote all of the Executive’s business time, energy, business judgment, knowledge and skill and the Executive’s reasonable 

  
 1 

 
best efforts to the performance of the Executive’s duties with the Company, provided that the foregoing shall not prevent the Executive from (i) serving on the boards of
directors of non-profit organizations and, with the prior written approval of the Board, other for profit companies, (ii) participating in charitable, civic, educational, professional, community or
industry affairs, and (iii) managing the Executive’s passive personal investments so long as such activities in the aggregate do not violate Section 11 hereof, interfere or conflict with the Executive’s duties hereunder or
create a business or fiduciary conflict. 
 2. EMPLOYMENT TERM. The Company agrees to employ the Executive pursuant to
the terms of this Agreement, and the Executive agrees to be so employed, for a term of three (3) years (the “Initial Term”) commencing upon the Effective Date. On each anniversary of the Effective Date following the Initial
Term, the term of this Agreement shall be automatically extended for successive one-year periods, provided, however, that either party hereto may elect not to extend this Agreement by giving
written notice to the other party at least ninety (90) days prior to any such anniversary date. Notwithstanding the foregoing, the Executive’s employment hereunder may be earlier terminated in accordance with Section 7 hereof,
subject to Section 8 hereof. The period of time between the Effective Date and the termination of the Executive’s employment hereunder shall be referred to herein as the “Employment Term.” 

3. BASE SALARY. The Company agrees to pay the Executive a base salary for calendar year 2010 at an annual rate of not less than
$510,000, payable in accordance with the regular payroll practices of the Company, but not less frequently than monthly. The Executive’s base salary shall be subject to annual review by the Board (or a committee thereof) during the first ninety
(90) days of each calendar year, and the base salary in respect of such calendar year may be increased above, but not decreased below, its level for the preceding calendar year, by the Board. The base salary as determined herein and adjusted
from time to time shall constitute “Base Salary” for purposes of this Agreement. 
 4. ANNUAL BONUS.
During the Employment Term, the Executive shall be eligible for an annual cash performance bonus (an “Annual Bonus”) in respect of each calendar year that ends during the Employment Term, to the extent earned based on performance
against objective performance criteria. The performance criteria for any particular calendar year shall be determined in good faith by the Board, no later than ninety (90) days after the commencement of such calendar year. The Executive’s
targeted Annual Bonus for a calendar year shall equal 75% of the Executive’s Base Salary for such calendar year (the “Target Bonus”) if target levels of performance for such year are achieved, with greater or lesser amounts
(including zero) paid for performance above and below target (such greater and lesser amounts to be determined by a formula established by the Board for such year when it establishes the targets and performance criteria for such year);
provided that the Executive’s maximum Annual Bonus for any calendar year during the Employment Term shall equal 200% of the Target Bonus for such calendar year. The Executive’s Annual Bonus for a calendar year shall be determined by
the Board after the end of the applicable calendar year based on the level of achievement of the applicable performance criteria, and shall be paid to the Executive in the calendar year following the calendar year to which such Annual Bonus relates
at the same time annual bonuses are paid to other senior executives of the Company, subject to continued employment at the time of payment (except as otherwise provided in Section 8 hereof).

 5. EQUITY AWARD. On the Effective Date, you will be granted incentive securities or
interests in one or more incentive securities, generally representing the right to participate in 0.55% of the capital appreciation of Parent. 
 6. EMPLOYEE BENEFITS. 
 (a) BENEFIT PLANS. During the Employment
Term, the Executive shall be entitled to participate in any employee benefit plan that the Company, Parent or any of their direct or indirectly controlled subsidiaries (each an “Affiliate”) h as adopted or may adopt, maintain or
contribute to and which benefit any of the senior executives of the Company, Parent or any Affiliate, on a basis no less favorable than that applicable to any such senior executives, subject to satisfying the applicable eligibility requirements,
except to the extent such plans are duplicative of the benefits otherwise provided hereunder. The Executive’s participation in any such employee benefit plan shall be subject to the terms of the applicable plan documents and generally
applicable Company policies. Notwithstanding the foregoing, the Company may modify or terminate any employee benefit plan at any time, if and to the extent allowed pursuant to the terms of such plan, provided that any such amendment may have no more
adverse affect on the Executive than on any other participant in such plan. The Company may provide perquisites to the Executive at the discretion of the Board. In addition, during the Employment Term, the Executive will be entitled to payment(s)
and/or the provision of service(s) pursuant to the Company’s relocation policy in connection with his relocation to the Headquarters City, provided that notwithstanding the terms of such policy, the sum of any capital loss (taking into account
transaction fees and broker’s commissions) and carrying costs experienced by the Executive associated with the sale of his Dallas, Texas residence, up to an additional $100,000, which are not covered by such policy shall be reimbursed to the
Executive. 
 (b) VACATIONS. During the Employment Term, the Executive shall be entitled to four (4) weeks of paid
vacation in accordance with the Company’s policy on accrual and use applicable to employees as in effect from time to time. 
 (c) BUSINESS EXPENSES. Upon presentation of reasonable substantiation and documentation as the Company may specify from time to time, the Executive shall be reimbursed in accordance with the
Company’s expense reimbursement policies as in effect from time to time, for all reasonable out-of-pocket business expenses incurred and paid by the Executive
during the Employment Term and in connection with the performance of the Executive’s duties hereunder. 
 7.
TERMINATION. The Executive’s employment and the Employment Term shall terminate on the first of the following to occur: 
 (a) DISABILITY. Upon ten (10) days’ prior written notice by the Company to the Executive of termination due to Disability. For purposes of this Agreement, “Disability”
shall be defined as the inability of the Executive to have performed the Executive’s material duties hereunder due to a physical or mental injury, infirmity or incapacity, which inability shall continue for one hundred and twenty
(120) consecutive days or for one hundred eighty (180) days (including weekends and holidays) in any 365-day period as determined by the Board in its reasonable discretion. The Executive shall
cooperate in all respects with the Company if a 

  
 3 

 
question arises as to whether the Executive has become disabled (including, without limitation, submitting to reasonable examinations by one or more medical doctors and other health care
specialists selected by the Company and authorizing such medical doctors and other health care specialists to discuss the Executive’s condition with the Company). 
 (b) DEATH. Automatically upon the date of death of the Executive. 
 (c)
CAUSE. Immediately upon written notice by the Company to the Executive of a termination for Cause. “Cause” shall mean the Executive’s (i) continued failure to follow the lawful directives of the Board or any

practices of the Company after written request for cooperation from the Board and a period of no less than ten (10) days to cure such failure; or (vii) breach of any of the restrictive covenants set forth in Section 11 hereof
or in any other written agreement between the Executive and the Company and/or its affiliates that causes material and demonstrable harm to the Company and that is not cured within fifteen (15) days of written notice from the Board (a
“Material Covenant Violation”). 
 (d) WITHOUT CAUSE. Immediately upon written notice by the Company to
the Executive of an involuntary termination without Cause (other than for death or Disability). 
 (e) GOOD REASON. Upon
written notice by the Executive to the Company of a termination for Good Reason. “Good Reason” shall mean the occurrence of any of the following events, without the express written consent of the Executive, unless such events are
fully corrected in all material respects by the Company or Parent (as applicable) within thirty (30) days following written notification by the Executive to the Company of the occurrence of one of the reasons set forth below: (i) the
material diminution in the Executive’s position, duties or authorities or assignment of duties materially inconsistent with the Executive’s position, including the Executive being required to report to someone other than the Company’s

notice of non-extension of this Agreement; or (v) the Company’s material breach of this Agreement. The Executive shall provide the Company with a written notice detailing the specific circumstances
alleged to constitute Good Reason within ninety (90) days the occurrence of such circumstances, and actually terminate employment within thirty (30) days following the expiration of the Company’s thirty
(30)-day correction period described above. Otherwise, any claim of such circumstances as “Good Reason” shall be deemed irrevocably waived by the Executive. 

(f) WITHOUT GOOD REASON. Upon ninety (90) days’ prior written notice by the Executive to the Company of the
Executive’s voluntary termination of employment without 

  
 4 

 
Good Reason (which the Company may, in its sole discretion, make effective earlier than any notice date). 
 (g) EXPIRATION OF EMPLOYMENT TERM; NON-EXTENSION OF AGREEMENT. Upon the expiration of the Employment Term due to a
non-extension of the Agreement by the Company or the Executive pursuant to the provisions of Section 2 hereof (in the case of a non-extension by the Company,
without the Executive having terminated for Good Reason in respect of such non-extension). 
 8. CONSEQUENCES OF TERMINATION. 
 (a) DEATH. In the event that the
Executive’s employment and the Employment Term ends on account of the Executive’s death, the Executive or the Executive’s estate, as the case may be, shall be entitled to the following (with the amounts due under Sections
8(a)(i) through 8(a)(v) hereof to be paid, unless otherwise provided below, within sixty (60) days following termination of employment, or such earlier date as may be required by applicable law): 

(i) any unpaid Base Salary through the date of termination; 
 (ii) any Annual Bonus earned but unpaid with respect to the calendar year ending on or preceding the date of termination; 

(iii) an amount equal to the pro-rata portion of the Executive’s Target
Bonus for the calendar year of termination (determined by multiplying the Target Bonus for the year of termination by a fraction, the numerator of which is the number of days during the calendar year of termination that the Executive is employed by
the Company and the denominator of which is 365); provided that to the extent that the payment of such amount constitutes “nonqualified deferred compensation” for purposes of “Code Section 409A” (as defined in
Section 25 hereof), such payment shall be made on the sixtieth (60th) day following such termination; 
 (iv) reimbursement for any unreimbursed
business expenses incurred through the date of termination; 
 (v) payment in respect of any accrued but unused vacation time in
accordance with Company policy; and 
 (vi) all other payments, benefits or fringe benefits to which the Executive shall be
entitled under the terms of any applicable compensation arrangement or benefit, equity or fringe benefit plan or program or grant or this Agreement (collectively, Sections 8(a)(i) through 8(a)(vi) hereof shall be hereafter referred to
as the “Accrued Benefits”). 
 (b) DISABILITY. In the event that the Executive’s employment and/or
Employment Term ends on account of the Executive’s Disability, the Company shall pay or provide the Executive with the Accrued Benefits. 
 (c) TERMINATION FOR CAUSE OR WITHOUT GOOD REASON OR AS A RESULT OF EXECUTIVE NON-EXTENSION OF THIS AGREEMENT. If the Executive’s employment is
terminated (x) by the Company for Cause or (y) by the Executive 

  
 5 

 
without Good Reason, the Company shall pay to the Executive the Accrued Benefits (other than the benefits described in Sections 8(a)(ii) and 8(a)(iii) hereof). 

(d) TERMINATION WITHOUT CAUSE OR FOR GOOD REASON. If the Executive’s employment by the Company is terminated (x) by the
Company other than for Cause pursuant to Section 7(c) hereof, or (y) by the Executive for Good Reason, the Company shall pay or provide the Executive with the following, subject to the provisions of Section 25 hereof:

 (i) the Accrued Benefits; 
 (ii) subject to the Executive’s not engaging in a Material Covenant Violation or a material breach of Section 11 hereof that is not cured within fifteen (15) days of written notice
from the Board (a “Material Cooperation Violation”), the Executive shall be entitled to an amount equal to one and one-half (1.5) multiplied by the sum of the Executive’s Base Salary
and Target Bonus for the year of termination (the “Severance Amount”), paid in equal monthly installments for a period of eighteen (18) months following such termination; provided that to the extent that the payment of
any amount constitutes “nonqualified deferred compensation” for purposes of Code Section 409A, any such payment scheduled to occur during the first sixty (60) days following the termination of employment shall not be paid until
the sixtieth (60th) day following such termination
and shall include payment of any amount that was otherwise scheduled to be paid prior thereto; and 
 (iii) subject to
(A) the Executive’s timely election of continuation coverage under the Consolidated Omnibus Budget Reconciliation Act of 1985, as amended (“COBRA”), (B) the Executive’s continued copayment of premiums at the same
level and cost to the Executive as if the Executive were an employee of the Company (excluding, for purposes of calculating cost, an employee’s ability to pay premiums with pre-tax dollars), and
(C) the Executive’s not engaging in a Material Covenant Violation or a Material Cooperation Violation, continued participation in the Company’s group health plan (to the extent permitted under applicable law) which covers the
Executive (and the Executive’s spouse) through the date Executive turns 65 (or, in the case of coverage for Executive’s current spouse, through the date that she turns 65 so long as she is then Executive’s spouse), at the
Company’s expense, provided that if the Company’s group health plan is self-insured, the Company will report to the appropriate tax authorities taxable income to the Executive equal to the portion of the deemed cost of such
participation (based on applicable COBRA rates) not paid by the Executive; and provided, further, that in the event that the Executive obtains other employment that offers group health benefits, such continuation of coverage by the
Company under this Section 8(d)(iii) shall immediately cease. For the sake of clarity, if the period specified in this Section 8(d)(iii) exceeds the statutory period during which the Executive may elect continuation coverage
under COBRA, the Company will provide the applicable benefits to Executive through procurement of an individual policy with respect to the Executive or by any other means chosen by the Company, at a cost to Executive no greater than the cost
specified in clause (B) of this Section 8(d)(iii). 
 Payments and benefits provided in this Section 8(d) shall be
in lieu of any termination or severance payments or benefits for which the Executive may be eligible under any of the plans, policies or programs of the Company or under the Worker Adjustment Retraining Notification Act of 1988 or any similar state
statute or regulation.

 (e) CHANGE IN CONTROL. 

(i) This Section 8(e) shall apply if the Executive’s employment by the Company is terminated
(x) by the Company other than for Cause pursuant to Section 7(c) hereof, or (y) by the Executive for Good Reason, in either case, during the two (2)-year period commencing upon a Change
in Control. Subject to the Executive’s not engaging in a Material Covenant Violation or a Material Cooperation Violation, upon a termination described in the preceding sentence, the Executive shall receive the benefits set forth in
Section 8(d) hereof, except that in lieu of receiving the Severance Amount in installments as contemplated under Section 8(d)(ii) hereof, the Executive shall receive a lump sum payment equal to the Severance Amount on the
date of such termination; provided that to the extent that the payment of the applicable amount constitutes “nonqualified deferred compensation” for purposes of Code Section 409A, such payment shall be made on the sixtieth
(60th) day following such termination. 

(ii) For purposes of this Agreement, the term “Change in Control” shall mean the consummation off the first transaction
following the Effective Date, whether in a single transaction or in a series of related transactions, in which any individual, entity or group (within the meaning of Section 13(d)(3) or 14(d)(2) of the Securities Exchange Act of 1934, as
amended) (a “Group”), other than Bain Capital Partners, any private equity fund managed by it, or any Group which includes Bain Capital Partners or any private equity fund managed by it, (A) acquires (whether by merger,
consolidation, or transfer or issuance of equity interests or otherwise) equity interests of the Company (or any surviving or resulting entity) representing more than fifty percent (50%) of the outstanding voting securities or economic value of
the Company (or any surviving or resulting entity), or (B) acquires assets constituting all or substantially all (more than eighty percent (80%)) of the assets of the Company and its subsidiaries (as determined on a consolidated basis).

 (f) CODE SECTION 280G. So long as the Company is described in Section 280G(b)(5)(A)(ii)(I) of the Code, in the
event that any payment that is either received by the Executive or paid by the Company on the Executive’s behalf or any property, or any other benefit provided to the Executive under the Agreement or under any other plan, arrangement or
agreement with the Company or any other person whose payments or benefits are treated as contingent on a change of ownership or control of the Company (or in the ownership of a substantial portion of the assets of the Company) or any person
affiliated with the Company or such person (but only if such payment or other benefit is in connection with the Executive’s employment by the Company) (collectively the “Company Payments”), would be subject to the tax imposed
by Section 4999 of the Code (and any similar tax that may hereafter be imposed by any taxing authority) (the “Excise Tax”), the Company shall, with respect to such Company Payments, use its reasonable best efforts to obtain a
vote satisfying the requirements of Section 280G(b)(5) of the Code, such that no portion of the Company Payments will be subject to such Excise Tax. In the event that a vote satisfying the requirements of Section 280G(b)(5) of the Code is
not obtained for any reason, then the Executive will be entitled to receive a portion of the Company Payments having a value equal to $1 less than three (3) times the Executive’s “base amount” (as such term is defined in
Section 280G(b)(3)(A) of the Code). Any reduction of the Company Payments pursuant to the foregoing shall occur in the following order: (i) any cash severance payable by reference to the Executive’s base salary or annual bonus;
(ii) any other 

  
 7 

 
cash amount payable to the Executive; (iii) any benefit valued as a “parachute payment;” and (iv) acceleration of vesting of any equity award. 

9. OTHER OBLIGATIONS. Upon any termination of the Executive’s employment with the Company, the Executive shall promptly
resign from any other position as an officer, director or fiduciary of the Company, Parent and any Affiliate. 
 10. RELEASE;
NO MITIGATION; NO SET-OFF. Any and all amounts payable and benefits or additional rights provided pursuant to this Agreement beyond the Accrued Benefits (other than the amount described in
Section 8(a)(iii) hereof) shall only be payable if the Executive delivers to the Company and does not revoke a general release of claims in favor of the Company in substantially the form of Exhibit A attached hereto. Such release
shall be executed and delivered (and no longer subject to revocation, if applicable) within sixty (60) days following termination. In no event shall the Executive be obligated to seek other employment or take any other action by way of
mitigation of the amounts payable to the Executive under any of the provisions of this Agreement, nor shall the amount of any payment hereunder be reduced by any compensation earned by the Executive as a result of employment by a subsequent employer
(except as provided in Section 8(d)(iii) hereof). The Company’s obligations to pay the Executive amounts hereunder shall not be subject to set-off, counterclaim or recoupment of amounts owed
by the Executive to the Company or any of its affiliates. 
 11. RESTRICTIVE COVENANTS. 

(a) CONFIDENTIALITY. During the course of the Executive’s employment with the Company, the Executive will learn confidential
information regarding the Company. The Executive agrees that the Executive shall not, directly or indirectly, use, make available, sell, disclose or otherwise communicate to any person, other than in the course of the Executive’s assigned
duties and for the benefit of the Company, either during the period of the Executive’s employment or at any time thereafter, any business and technical information or trade secrets, nonpublic, proprietary or confidential information, knowledge
or data relating to the Company or any of its Affiliates, or received from third parties subject to a duty on the Company’s and its Affiliates’ part to maintain the confidentiality of such information and to use it only for certain limited
purposes, in each case which shall have been obtained by the Executive during the Executive’s employment by the Company. The foregoing shall not apply to information that (i) was known to the public prior to its disclosure to the
Executive; (ii) becomes generally known to the public subsequent to disclosure to the Executive through no wrongful act of the Executive or any representative of the Executive; or (iii) the Executive is required to disclose by applicable
law, regulation or legal process (provided that the Executive provides the Company with prior notice of the contemplated disclosure and cooperates with the Company at its expense in seeking a protective order or other appropriate protection
of such information). The terms and conditions of this Agreement shall remain strictly confidential, and the Executive hereby agrees not to disclose the terms and conditions hereof to any person or entity, other than immediate family members, legal
advisors or personal tax or financial advisors, or prospective future employers solely for the purpose of disclosing the limitations on the Executive’s conduct imposed by the provisions of this Section 11 who, in each case, shall be
instructed by the Executive to keep such information confidential. 

  
 8 

 (b) NONCOMPETITION. The Executive acknowledges that the Executive performs services
of a unique nature for the Company that are irreplaceable, and that the Executive’s performance of such services to a competing business will result in irreparable harm to the Company. Accordingly, during the Executive’s employment
hereunder and for a period of one (1) year thereafter, the Executive agrees that the Executive will not, directly or indirectly, own, manage, operate, control, be employed by (whether as an employee, consultant, independent contractor or
otherwise, and whether or not for compensation) or render services to any person, firm, corporation or other entity, in whatever form, engaged in competition with any material business of the Company or any Affiliate or in any other material
business in which the Company or any Affiliate has taken material steps and has material plans, on or prior to the date or termination, to be engaged in on or after such date, in any locale of any country in which the Company or such Affiliate
conducts business. Notwithstanding the foregoing, nothing herein shall prohibit the Executive from being a passive owner of not more than one percent (1%) of the equity securities of a publicly traded corporation engaged in a business that is
in competition with the Company or any of its affiliates, so long as the Executive has no active participation in the business of such corporation. In no event shall the provisions of this Section 11(b) apply to the Executive’s
practice as an attorney to the extent prohibited by law. 
 (c) NONSOLICITATION; NONINTERFERENCE. During the
Executive’s employment with the Company and for a period of one (1) year thereafter, the Executive agrees that the Executive shall not, except in the furtherance of the Executive’s duties hereunder, directly or indirectly,
individually or on behalf of any other person, firm, corporation or other entity, (i) solicit, aid or induce any customer of the Company or an Affiliate to purchase goods or services then sold by the Company or any Affiliate from another
person, firm, corporation or other entity or assist or aid any other persons or entity in identifying or soliciting any such customer, (ii) solicit, aid or induce any employee, representative or agent of the Company or any Affiliate to leave
such employment or retention or, in the case of employees, to accept employment with or render services to or with any other person, firm, corporation or other entity unaffiliated with the Company or any Affiliate, or hire or retain any such
employee, or take any action to materially assist or aid any other person, firm, corporation or other entity in identifying, hiring or soliciting any such employee, or (iii) interfere, or aid or induce any other person or entity in interfering,
with the relationship between the Company or any Affiliate and any of their respective vendors, joint venturers or licensors. An employee, representative or agent shall be deemed covered by this Section 11(c) while so employed or
retained and for a period of six (6) months thereafter. Notwithstanding the foregoing, the provisions of this Section 11(c) shall not be violated by general advertising or solicitation not specifically targeted at Company or
Affiliate-related individuals or entities. 
 (d) INVENTIONS. (i) The Executive acknowledges and agrees that all
ideas, methods, inventions, discoveries, improvements, work products, developments or works of authorship, in any such case, of a scientific nature (“Inventions”), whether patentable or unpatentable, (A) that relate to the
Executive’s work with the Company, made or conceived by the Executive, solely or jointly with others, during the Employment Term, or (B) suggested by any work that the Executive performs in connection with the Company, either while
performing the Executive’s duties with the Company or on the Executive’s own time, shall belong exclusively to the Company (or its designee), whether or not patent applications are filed thereon. The Executive will keep full and complete
written records (the “Records”), in the 

  
 9 

 
manner prescribed by the Company, of all Inventions, and will promptly disclose all Inventions completely and in writing to the Company. The Records shall be the sole and exclusive property of
the Company, and the Executive will surrender them upon the termination of the Employment Term, or upon the Company’s request. The Executive will assign to the Company the Inventions and all patents that may issue thereon in any and all
countries, whether during or subsequent to the Employment Term, together with the right to file, in the Executive’s name or in the name of the Company (or its designee), applications for patents and equivalent rights (the
“Applications”). The Executive will, at any time during and subsequent to the Employment Term, make such applications, sign such papers, take all rightful oaths, and perform all acts as may be requested from time to time by the
Company with respect to the Inventions. The Executive will also execute assignments to the Company (or its designee) of the Applications, and give the Company and its attorneys all reasonable assistance (including the giving of testimony) to obtain
the Inventions for the Company’s benefit, all without additional compensation to the Executive from the Company. 
 (ii) In
addition, the Inventions will be deemed Work for Hire, as such term is defined under the copyright laws of the United States, on behalf of the Company and the Executive agrees that the Company will be the sole owner of the Inventions, and all
underlying rights therein, in all media now known or hereinafter devised, throughout the universe and in perpetuity without any further obligations to the Executive. If the Inventions, or any portion thereof, are deemed not to be Work for Hire, the
Executive hereby irrevocably conveys, transfers and assigns to the Company, all rights, in all media now known or hereinafter devised, throughout the universe and in perpetuity, in and to the Inventions, including, without limitation, all of the
Executive’s right, title and interest in the copyrights (and all renewals, revivals and extensions thereof) to the Inventions, including, without limitation, all rights of any kind or any nature now or hereafter recognized, including, without
limitation, the unrestricted right to make modifications, adaptations and revisions to the Inventions, to exploit and allow others to exploit the Inventions and all rights to sue at law or in equity for any infringement, or other unauthorized use or
conduct in derogation of the Inventions, known or unknown, prior to the date hereof, including, without limitation, the right to receive all proceeds and damages therefrom. In addition, the Executive hereby waives any
so-called “moral rights” with respect to the Inventions. To the extent that the Executive has any rights in the results and proceeds of the Inventions that cannot be assigned in the manner described
herein, the Executive agrees to unconditionally waive the enforcement of such rights. The Executive hereby waives any and all currently existing and future monetary rights in and to the Inventions and all patents that may issue thereon, including,
without limitation, any rights that would otherwise accrue to the Executive’s benefit by virtue of the Executive being an employee of or other service provider to the Company. 

(e) RETURN OF COMPANY PROPERTY. On the date of the Executive’s termination of employment with the Company for any reason (or
at any time prior thereto at the Company’s request), the Executive shall return all property belonging to the Company or its Affiliates (including, but not limited to, any Company-provided laptops, computers, cell phones, wireless electronic
mail devices or other equipment, or documents and property belonging to the Company). The Executive may retain the Executive’s rolodex and similar address books provided that such items only include contact information. 

  
 10 

 (f) REASONABLENESS OF COVENANTS. In signing this Agreement, the Executive
gives the Company assurance that the Executive has carefully read and considered all of the terms and conditions of this Agreement, including the restraints imposed under this Section 11. The Executive agrees that these restraints are
necessary for the reasonable and proper protection of the Company and its Affiliates and their trade secrets and confidential information and that each and every one of the restraints is reasonable in respect to subject matter, length of time and
geographic area, and that these restraints, individually or in the aggregate, will not prevent the Executive from obtaining other suitable employment during the period in which the Executive is bound by the restraints. The Executive acknowledges
that each of these covenants has a unique, very substantial and immeasurable value to the Company and its Affiliates and that the Executive has sufficient assets and skills to provide a livelihood while such covenants remain in force. The Executive
further covenants that the Executive will not challenge the reasonableness or enforceability of any of the covenants set forth in this Section 11, other than in response to an attempt by the Company or an Affiliate to enforce such
covenants against the Executive. It is also agreed that the Affiliates will have the right to enforce all of the Executive’s obligations to such Affiliates under this Agreement, including without limitation pursuant to this
Section 11. 
 (g) REFORMATION. If it is determined by a court of competent jurisdiction in any state
that any restriction in this Section 11 is excessive in duration or scope or is unreasonable or unenforceable under applicable law, it is the intention of the parties that such restriction may be modified or amended by the court to
render it enforceable to the maximum extent permitted by the laws of that state. 
 (h) TOLLING. In the
event of any violation of the provisions of this Section 11, the Executive acknowledges and agrees that the post-termination restrictions contained in this Section 11 shall be extended by a period of time equal to the period
of such violation, it being the intention of the parties hereto that the running of the applicable post-termination restriction period shall be tolled during any period of such violation. 

(i) SURVIVAL OF PROVISIONS. The obligations contained in Sections 11 and 12 hereof shall survive the
termination or expiration of the Employment Term and the Executive’s employment with the Company and shall be fully enforceable thereafter. 
 12. COOPERATION. Upon the receipt of reasonable notice from the Company (including through outside counsel), the Executive agrees that while employed by the Company and thereafter (to the extent it
does not materially interfere with the Executive’s employment or other business activities after employment by the Company), the Executive will respond and provide information with regard to matters in which the Executive has knowledge as a
result of the Executive’s employment with the Company, and will provide reasonable assistance to the Company, the Affiliates and their respective representatives in defense of all claims that may be made against the Company or the Affiliates,
and will assist the Company and the Affiliates in the prosecution of all claims that may be made by the Company or the Affiliates, to the extent that such claims may relate to the period of the Executive’s employment with the Company. The
Executive also agrees to promptly inform the Company (to the extent that the Executive is legally permitted to do so) if the Executive is asked to assist in any investigation of the Company or the Affiliates (or their actions), regardless of whether
a lawsuit or other proceeding has then 

  
 11 

 
been filed against the Company or Affiliates with respect to such investigation, and shall not do so unless legally required. Upon presentation of appropriate documentation, the Company shall pay
or reimburse the Executive for all reasonable out-of-pocket travel, duplicating, telephonic, counsel and other expenses incurred by the Executive in complying with this
Section 12. 
 13. EQUITABLE RELIEF AND OTHER REMEDIES. The Executive acknowledges and agrees that the
Company’s remedies at law for a breach or threatened breach of any of the provisions of Section 11 hereof or Section 12 hereof would be inadequate and, in recognition of this fact, the Executive agrees that, in the event
of such a breach or threatened breach, in addition to any remedies at law, the Company shall be entitled to obtain equitable relief in the form of specific performance, a temporary restraining order, a temporary or permanent injunction or any other
equitable remedy which may then be available. In the event of a Material Covenant Violation or a Material Cooperation Violation by the Executive, any severance being paid to the Executive pursuant to this Agreement or otherwise shall immediately
cease. 
 14. NO ASSIGNMENTS. This Agreement is personal to each of the parties hereto. Except as provided in this
Section 14 hereof, no party may assign or delegate any rights or obligations hereunder without first obtaining the written consent of the other party hereto. The Company shall assign this Agreement to any successor to all or
substantially all of the business and/or assets of the Company or Parent, provided that the Company shall require such successor to expressly assume and agree to perform this Agreement in the same manner and to the same extent that the
Company would be required to perform it if no such succession had taken place, and provided that the Company agrees to perform such obligations if such successor fails to do so in a timely manner. As used in this Agreement,
“Company” shall mean the Company and any successor to all or substantially all of its business and/or assets, which assumes and agrees to perform the duties and obligations of the Company under this Agreement by operation of law or
otherwise. 
 15. NOTICES. For purposes of this Agreement, notices and all other communications provided for in this
Agreement shall be in writing and shall be deemed to have been duly given (a) on the date of delivery, if delivered by hand, (b) on the date of transmission, if delivered by confirmed facsimile or electronic mail, (c) on the first

16. SECTION HEADINGS; INCONSISTENCY. The section headings used in this Agreement are included solely for convenience and shall not
affect, or be used in connection with, the interpretation of this Agreement. In the event of any inconsistency between the terms of this Agreement (including the Exhibits hereto) and any form, award, plan or policy of the Company, the terms of this
Agreement shall govern and control. 
 17. SEVERABILITY. The provisions of this Agreement shall be deemed severable and
the invalidity or unenforceability of any provision shall not affect the validity or enforceability of the other provisions hereof. 
 18. COUNTERPARTS. This Agreement may be executed in several counterparts, each of which shall be deemed to be an original but all of which together will constitute one and the same instrument.

 19. INDEMNIFICATION. The Company hereby agrees to indemnify the Executive and hold the Executive harmless to the
fullest extent allowable under applicable law against and in respect of any and all actions, suits, proceedings, claims, demands, judgments, costs, expenses (including attorney’s fees, and the advancement of such fees subject to any legally
required repayment undertaking), losses, and damages resulting from the Executive’s performance of the Executive’s duties and obligations with the Company. This obligation shall survive the termination of the Executive’s employment
with the Company. 
 20. LIABILITY INSURANCE. The Company shall cover the Executive under directors’ and
officers’ liability insurance both during and, while potential liability exists, after the Employment Term in the same amount and to the same extent as the Company covers its other officers and directors. 

21. GOVERNING LAW. This Agreement, the rights and obligations of the parties hereto, and any claims or disputes relating thereto,
shall be governed by and construed in accordance with the laws of the State of Delaware (but not including any choice of law rule thereof that would cause the laws of another jurisdiction to apply). 

22. DISPUTE RESOLUTION. Each of the parties agrees that any dispute between the parties shall be resolved only in the courts of
the State of Delaware or the United States District Court for the District of Delaware and the appellate courts having jurisdiction of appeals in such courts. In that context, and without limiting the generality of the foregoing, each of the parties
hereto irrevocably and unconditionally (a) submits in any proceeding relating to this Agreement or the Executive’s employment by the Company or any affiliate, or for the recognition and enforcement of any judgment in respect thereof (a
“Proceeding”), to the exclusive jurisdiction of the courts of the State of Delaware, the court of the United States of America for the District of Delaware, and appellate courts having jurisdiction of appeals from

  
 13 

 
any of the foregoing, and agrees that all claims in respect of any such Proceeding shall be heard and determined in such Delaware State court or, to the extent permitted by law, in such federal
court, (b) consents that any such Proceeding may and shall be brought in such courts and waives any objection that the Executive or the Company may now or thereafter have to the venue or jurisdiction of any such Proceeding in any such court or
that such Proceeding was brought in an inconvenient court and agrees not to plead or claim the same, (c) WAIVES ALL RIGHT TO TRIAL BY JURY IN ANY PROCEEDING (WHETHER BASED ON CONTRACT, TORT OR OTHERWISE) ARISING OUT OF OR RELATING TO THIS
AGREEMENT OR THE EXECUTIVE’S EMPLOYMENT BY THE COMPANY OR ANY AFFILIATE OF THE COMPANY, OR THE EXECUTIVE’S OR THE COMPANY’S PERFORMANCE UNDER, OR THE ENFORCEMENT OF, THIS AGREEMENT, (d) agrees that service of process in any such
Proceeding may be effected by mailing a copy of such process by registered or certified mail (or any substantially similar form of mail), postage prepaid, to such party at the Executive’s or the Company’s address as provided in
Section 15 hereof, and (e) agrees that nothing in this Agreement shall affect the right to effect service of process in any other manner permitted by the laws of the State of Delaware. Each party shall be responsible for its own
legal fess incurred in connection with any dispute hereunder. 
 23. MISCELLANEOUS. No provision of this Agreement may be
modified, waived or discharged unless such waiver, modification or discharge is agreed to in writing and signed by the Executive and such officer or director as may be designated by the Board. No waiver by either party hereto at any time of any
breach by the other party hereto of, or compliance with, any condition or provision of this Agreement to be performed by such other party shall be deemed a waiver of similar or dissimilar provisions or conditions at the same or at any prior or
subsequent time. This Agreement together with all exhibits hereto sets forth the entire agreement of the parties hereto in respect of the subject matter contained herein and supersedes any and all prior agreements or understandings between the
Executive and the Company with respect to the subject matter hereof, whether written or oral. No agreements or representations, oral or otherwise, express or implied, with respect to the subject matter hereof have been made by either party which are
not expressly set forth in this Agreement. 
 24. REPRESENTATIONS; ACTIONS BY PRIOR EMPLOYERS. The Executive represents
and warrants to the Company that (a) the Executive has used the Executive’s best efforts to provide the Company with (i) each agreement with a predecessor employer which may have any bearing on the Executive’s legal right to
enter into this Agreement and to perform all of the obligations on the Executive’s part to be performed hereunder in accordance with its terms, or (ii) a summary of the applicable provisions of each such agreement which the Executive may
not provide to the Company due to an existing confidentiality obligation, and (b) other than the agreements referenced in the preceding clause (a), the Executive is not a party to any agreement or understanding, whether written or oral, and is
not subject to any restriction (including, without limitation, any non-competition restriction from a prior employer), which, in either case, could prevent the Executive from entering into this Agreement or
performing all of the Executive’s duties and obligations hereunder. The Executive understands that the foregoing representations are a material inducement to the Company entering into this Agreement, and to the extent that either of such
representations is untrue in any material respect at any time or for any reason, this Agreement shall be voidable by the Company such that the parties hereunder shall be relieved of all of their respective duties and obligations 

  
 14 

 
hereunder; provided that any termination of the Executive’s employment resulting from the Company exercising its rights pursuant to this sentence shall be treated as a termination of
employment by the Executive without Good Reason. If any prior employer of the Executive, or any affiliate of any such prior employer, challenges the Executive’s right to enter into this Agreement and to perform all of the Executive’s
obligations hereunder (whether by action against the Executive, the Company, Parent and/or an Affiliate), the Company, Parent (on behalf of itself and all Affiliates) and the Executive each agree to use their reasonable best efforts to defend
against such challenge. 
 25. TAX MATTERS. 
 (a) WITHHOLDING. The Company may withhold from any and all amounts payable under this Agreement or otherwise such federal, state and local taxes as may be required to be withheld pursuant to any
applicable law or regulation. 
 (b) SECTION 409A COMPLIANCE. 

(i) The intent of the parties is that payments and benefits under this Agreement comply with Section 409A of the Code and the
regulations and guidance promulgated thereunder (collectively “Code Section 409A”) and, accordingly, to the maximum extent permitted, this Agreement shall be interpreted to be in compliance therewith. To the extent that any
provision hereof is modified in order to comply with Code Section 409A, such modification shall be made in good faith and shall, to the maximum extent reasonably possible, maintain the original intent and economic benefit to the Executive and
the Company of the applicable provision without violating the provisions of Code Section 409A. Any such modification shall require the written consent of the Executive. In no event whatsoever shall the Company be liable for any additional tax,
interest or penalty that may be imposed on the Executive by Code Section 409A or damages for failing to comply with Code Section 409A; provided that the Company makes any modification reasonably requested by the Executive in
accordance with the second sentence of this Section 25(b)(i). 
 (ii) A termination of employment shall not be
deemed to have occurred for purposes of any provision of this Agreement providing for the payment of any amounts or benefits upon or following a termination of employment unless such termination is also a “separation from service” within
the meaning of Code Section 409A and, for purposes of any such provision of this Agreement, references to a “termination,” “termination of employment” or like terms shall mean “separation from service.” If the
Executive is deemed on the date of termination to be a “specified employee” within the meaning of that term under Code Section 409A(a)(2)(B), then with regard to any payment or the provision of any benefit that is considered
“nonqualified deferred compensation” under Code Section 409A payable on account of a “separation from service,” such payment or benefit shall be made or provided at the date which is the earlier of (A) the expiration of
the six (6)-month period measured from the date of such “separation from service” of the Executive, and (B) the date of the Executive’s death, to the extent required under Code
Section 409A. Upon the expiration of the foregoing delay period, all payments and benefits delayed pursuant to this Section 25(b)(ii) (whether they would have otherwise been payable in a single sum or in installments in the absence
of such delay) shall be paid or reimbursed to the Executive in a lump sum and all remaining payments and benefits due 

  
 15 

 
under this Agreement shall be paid or provided in accordance with the normal payment dates specified for them herein. 
 (iii) To the extent that reimbursements or other in-kind benefits under this Agreement constitute “nonqualified deferred compensation” for purposes of
Code Section 409A, (A) all expenses or other reimbursements hereunder shall be made on or prior to the last day of the taxable year following the taxable year in which such expenses were incurred by the Executive, (B) any right to
reimbursement or in-kind benefits shall not be subject to liquidation or exchange for another benefit, and (C) no such reimbursement, expenses eligible for reimbursement, or
in-kind benefits provided in any taxable year shall in any way affect the expenses eligible for reimbursement, or in-kind benefits to be provided, in any other taxable
year. 
 (iv) For purposes of Code Section 409A, the Executive’s right to receive installment payments pursuant to
this Agreement shall be treated as a right to receive a series of separate and distinct payments. Whenever a payment under this Agreement specifies a payment period with reference to a number of days, the actual date of payment within the specified
period shall be within the sole discretion of the Company. 
 26. FURTHER ASSURANCES; PARENT GUARANTEE. The parties
hereto shall cooperate with each other and do, or procure the doing of, all acts and things, and execute, or procure the execution of, all documents, as may reasonably be required to give full effect to this Agreement. Parent hereby guarantees the
performance of the obligations of the Company to pay all cash amounts due to the Executive pursuant to this Agreement. In the event that the Company is unable or unwilling to pay any such amounts when due, upon notice of such non-payment received by Parent from the Executive, Parent shall immediately pay such amounts, or take any and all actions necessary to cause one or more Affiliates to pay such amounts, on behalf of the Company.

 EXHIBIT A 
 GENERAL RELEASE 
 I, Curtis S. Shaw, in consideration of and subject
to the performance by Bain Capital Everest US Holding, Inc. (together with its subsidiaries, the “Company” ), of its obligations under the Employment Agreement, dated as of July 1, 2010 (the “Agreement” ), do
hereby release and forever discharge as of the date hereof the Company and its respective “Affiliates” (as defined in the Agreement) and all present, former and future directors, officers, employees, successors and assigns of the Company
and its Affiliates and direct or indirect owners (collectively, the “Released Parties” ) to the extent provided below. The Released Parties are intended third-party beneficiaries of this General Release, and this General Release may
be enforced by each of them in accordance with the terms hereof in respect of the rights granted to such Released Parties hereunder. Terms used herein but not otherwise defined shall have the meanings given to them in the Agreement. 

1. I understand that any payments or benefits paid or granted to me under Section 8 of the Agreement represent, in part, consideration for signing
this General Release and are not salary, wages or benefits to which I was already entitled. I understand and agree that I will not receive certain of the payments and benefits specified in Section 8 of the Agreement unless I execute this
General Release and do not revoke this General Release within the time period permitted hereafter. Such payments and benefits will not be considered compensation for purposes of any employee benefit plan, program, policy or arrangement maintained or
hereafter established by the Company or its affiliates. 
 2. Except as provided in paragraphs 4 and 5 below and except for the provisions of
the Agreement which expressly survive the termination of my employment with the Company, I knowingly and voluntarily (for myself, my heirs, executors, administrators and assigns) release and forever discharge the Company and the other Released
Parties from any and all claims, suits, controversies, actions, causes of action, cross-claims, counter-claims, demands, debts, compensatory damages, liquidated damages, punitive or exemplary damages, other damages, claims for costs and
attorneys’ fees, or liabilities of any nature whatsoever in law and in equity, both past and present (through the date this General Release becomes effective and enforceable) and whether known or unknown, suspected, or claimed against the
Company or any of the Released Parties which I, my spouse, or any of my heirs, executors, administrators or assigns, may have, which arise out of or are connected with my employment with, or my separation or termination from, the Company (including,
but not limited to, any allegation, claim or violation, arising under: Title VII of the Civil Rights Act of 1964, as amended; the Civil Rights Act of 1991; the Age Discrimination in Employment Act of 1967, as amended (including the Older Workers
Benefit Protection Act); the Equal Pay Act of 1963, as amended; the Americans with Disabilities Act of 1990; the Family and Medical Leave Act of 1993; the Worker Adjustment Retraining and Notification Act; the Employee Retirement Income Security Act
of 1974; any applicable Executive Order Programs; the Fair Labor Standards Act; or their state or local counterparts; or under any other federal, state or local civil or human rights law, or under any other local, state, or federal law, regulation
or ordinance; or under any public policy, contract or tort, or under common law; or arising under any policies, practices or procedures of the Company; or any claim for wrongful discharge, breach of contract, infliction of emotional

  
 A-1

 
distress, defamation; or any claim for costs, fees, or other expenses, including attorneys’ fees incurred in these matters) (all of the foregoing collectively referred to herein as the
“Claims”). 
 3. I represent that I have made no assignment or transfer of any right, claim, demand, cause of action, or other
matter covered by paragraph 2 above. 
 4. I agree that this General Release does not waive or release any rights or claims that I may have
which arise after the date I execute this General Release, including, without limitation, Claims under the Age Discrimination in Employment Act of 1967. I acknowledge and agree that my separation from employment with the Company in compliance with
the terms of the Agreement shall not serve as the basis for any claim or action (including, without limitation, any claim under the Age Discrimination in Employment Act of 1967). 
 5. I agree that I hereby waive all rights to sue or obtain equitable, remedial or punitive relief from any or all Released Parties of any kind whatsoever in respect of any Claim, including, without
limitation, reinstatement, back pay, front pay, and any form of injunctive relief. Notwithstanding the above, I further acknowledge that I am not waiving and am not being required to waive any right that cannot be waived under law, including the
right to file an administrative charge or participate in an administrative investigation or proceeding; provided, however, that I disclaim and waive any right to share or participate in any monetary award resulting from the prosecution of such
charge or investigation or proceeding. Additionally, I am not waiving any right to the Accrued Benefits or claims for indemnity or contribution. 
 6. In signing this General Release, I acknowledge and intend that it shall be effective as a bar to each and every one of the Claims hereinabove mentioned or implied. I expressly consent that this General
Release shall be given full force and effect according to each and all of its express terms and provisions, including those relating to unknown and unsuspected Claims (notwithstanding any state or local statute that expressly limits the
effectiveness of a general release of unknown, unsuspected and unanticipated Claims), if any, as well as those relating to any other Claims hereinabove mentioned or implied. I acknowledge and agree that this waiver is an essential and material term
of this General Release and that without such waiver the Company would not have agreed to the terms of the Agreement. I further agree that in the event I should bring a Claim seeking damages against the Company, or in the event I should seek to
recover against the Company in any Claim brought by a governmental agency on my behalf, this General Release shall serve as a complete defense to such Claims to the maximum extent permitted by law. I further agree that I am not aware of any pending
claim of the type described in paragraph 2 as of the execution of this General Release. 
 7. I agree that neither this General Release, nor the
furnishing of the consideration for this General Release, shall be deemed or construed at any time to be an admission by the Company, any Released Party or myself of any improper or unlawful conduct. 

8. I agree that if I violate this General Release by suing the Company or the other Released Parties, I will pay all costs and expenses of defending
against the suit incurred by the Released Parties, including reasonable attorneys’ fees. 

  
 A-2

 9. I agree that this General Release and the Agreement are confidential and agree not to disclose any
information regarding the terms of this General Release or the Agreement, except to my immediate family and any tax, legal or other counsel I have consulted regarding the meaning or effect hereof or as required by law, and I will instruct each of
the foregoing not to disclose the same to anyone. The Company agrees to disclose any such information only to any tax, legal or other counsel of the Company as required by law. 
 10. Any non-disclosure provision in this General Release does not prohibit or restrict me (or my attorney) from responding to any inquiry about this General Release
or its underlying facts and circumstances by the Securities and Exchange Commission (SEC), the Financial Industry Regulatory Authority (FINRA), any other self-regulatory organization or any governmental entity. 

11. I hereby acknowledge that Sections 8, 10, 11, 12, 13, 15, 17, 18, 19, 21, 22, 25 and 26 of the Agreement shall survive my execution of this General
Release. 
 12. I represent that I am not aware of any claim by me other than the claims that are released by this General Release. I
acknowledge that I may hereafter discover claims or facts in addition to or different than those which I now know or believe to exist with respect to the subject matter of the release set forth in paragraph 2 above and which, if known or suspected
at the time of entering into this General Release, may have materially affected this General Release and my decision to enter into it. 
 13.
Notwithstanding anything in this General Release to the contrary, this General Release shall not relinquish, diminish, or in any way affect any rights or claims arising out of any breach by the Company or by any Released Party of the Agreement after
the date hereof. 
 14. Whenever possible, each provision of this General Release shall be interpreted in, such manner as to be effective and
valid under applicable law, but if any provision of this General Release is held to be invalid, illegal or unenforceable in any respect under any applicable law or rule in any jurisdiction, such invalidity, illegality or unenforceability shall not
affect any other provision or any other jurisdiction, but this General Release shall be reformed, construed and enforced in such jurisdiction as if such invalid, illegal or unenforceable provision had never been contained herein. 

BY SIGNING THIS GENERAL RELEASE, I REPRESENT AND AGREE THAT: 
  

	 	1.	I HAVE READ IT CAREFULLY; 

  

	 	2.	I UNDERSTAND ALL OF ITS TERMS AND KNOW THAT I AM GIVING UP IMPORTANT RIGHTS, INCLUDING BUT NOT LIMITED TO, RIGHTS UNDER THE AGE DISCRIMINATION IN EMPLOYMENT ACT OF
1967, AS AMENDED, TITLE VII OF THE CIVIL RIGHTS ACT OF 1964, AS AMENDED; THE EQUAL PAY ACT OF 1963, THE AMERICANS WITH DISABILITIES ACT OF 1990; AND THE EMPLOYEE RETIREMENT INCOME SECURITY ACT OF 1974, AS AMENDED; 

 

	 	3.	I VOLUNTARILY CONSENT TO EVERYTHING IN IT; 

  
 A-3

	 	4.	I HAVE BEEN ADVISED TO CONSULT WITH AN ATTORNEY BEFORE EXECUTING IT AND I HAVE DONE SO OR, AFTER CAREFUL READING AND CONSIDERATION I HAVE CHOSEN NOT TO DO SO OF MY OWN
VOLITION;

 AMENDMENT NO. 2 TO EMPLOYMENT AGREEMENT 

THIS AMENDMENT NO. 2 TO EMPLOYMENT AGREEMENT (this “Amendment”) is made and entered into as of February 14,
2012, by and among Bain Capital Everest US Holding, Inc., a Delaware corporation (the “Company”), Bain Capital Everest Manager Holding SCA, a Luxembourg incorporated company (“Parent”) and Curtis S. Shaw (the
“Executive”). 
 W I T N E S S E T H:

 WHEREAS, the Company, Parent and the Executive entered into an Employment Agreement dated as of July 1, 2010,
which was amended on August 18, 2010 (collectively, the “Agreement”); and 
 WHEREAS, the Company,
Parent and the Executive desire to amend certain terms and conditions of the Agreement as set forth herein. 
 NOW,
THEREFORE, in consideration of the mutual covenants set forth in this Amendment, the Company, Parent and the Executive hereby agree as follows: 
 1. Amendment. Section 8(f) of the Agreement is hereby amended and restated to read in full as follows: 
 “(f) CODE SECTION 280G. 
 (i) Change in Control
Prior to Publicly Traded Equity of Company. So long as the Company is described in Section 280G(b)(5)(A)(ii)(I) of the Code, in the event that any payment that is either received by the Executive or paid by the Company on the
Executive’s behalf or any property, or any other benefit provided to the Executive under the Agreement or under any other plan, arrangement or agreement with the Company or any other person whose payments or benefits are treated as contingent
on a change of ownership or control of the Company (or in the ownership of a substantial portion of the assets of the Company) or any person affiliated with the Company or such person (but only if such payment or other benefit is in connection with
the Executive’s employment by the Company) (collectively the “Company Payments”), would be subject to the tax imposed by Section 4999 of the Code (and any similar tax that may hereafter be imposed by any taxing authority)
(the “Excise Tax”), the Company shall, with respect to such Company Payments, use its reasonable best efforts to obtain a vote satisfying the requirements of Section 280G(b)(5) of the Code, such that no portion of the Company
Payments will be subject to such Excise Tax. In the event that a vote satisfying the requirements of Section 280G(b)(5) of the Code is not obtained for any reason, then the Executive will be entitled to receive a portion of the Company Payments
having a value equal to $1 less than three (3) times the Executive’s “base amount” (as such term is defined in Section 280G(b)(3)(A) of the Code) (the “Safe

 
Harbor Amount”). Any reduction of the Company Payments pursuant to the foregoing shall occur in the following order: (A) any cash severance payable by reference to the
Executive’s base salary or annual bonus; (B) any other cash amount payable to the Executive; (C) any benefit valued as a “parachute payment;” and (D) acceleration of vesting of any equity award. 

(ii) Change in Control Upon or Following Publicly Traded Equity of Company. In the event that Company Payments
become payable to the Executive during any period in which the Company is not an entity described in Section 280G(b)(5)(A)(ii)(I) of the Code, if the Company Payments will be subject to the Excise Tax, then the Executive will be entitled to
receive either (A) the full amount of the Company Payments, or (B) a portion of the Company Payments having a value equal to the Safe Harbor Amount, whichever of clauses (A) and (B), after taking into account applicable federal,
state, and local income taxes and the Excise Tax, results in the receipt by the Executive on an after-tax basis, of the greatest portion of the Company Payments. Any reduction of the Company Payments pursuant to the foregoing shall occur in the same
manner as provided in the last sentence of Section 8(f)(i) hereof. 
 (iii) Accountants. Any
determination required under this Section 8(f) shall be made in writing by the independent public accountants of the Company, whose determination shall be conclusive and binding for all purposes upon the Company and the Executive. For purposes
of making any calculation required by this Section 8(f), such accountants may make reasonable assumptions and approximations concerning applicable taxes and may rely on reasonable, good-faith interpretations concerning the application of
Sections 280G and 4999 of the Code.” 
 2. Affirmation. This Amendment is to be read and construed with the
Agreement as constituting one and the same agreement. Except as specifically modified by this Amendment, all remaining provisions, terms and conditions of the Agreement shall remain in full force and effect. 

3. Defined Terms. All terms not herein defined shall have the meanings ascribed to them in the Agreement. 

4. Counterparts. This Amendment may be executed in one or more counterparts, each of which shall be deemed to be an original but
all of which together shall constitute one and the same instrument.
