Exhibit 10.7

FORM OF DIRECTOR AND OFFICER INDEMNIFICATION AGREEMENT

THIS INDEMNIFICATION AGREEMENT (the “Agreement”), between Portillo’s Inc., a Delaware corporation (the “Company”), and the undersigned (“Indemnitee”), dated as of the date last written below, is effective as of the date of the effectiveness of the Company’s Registration Statement on Form S-1 relating to its initial public offering. Capitalized terms not defined elsewhere in this Agreement are used as defined in Section 13.

WHEREAS, the Board of Directors of the Company (the “Board”) has determined that it is reasonable, prudent and necessary for the Company contractually to obligate itself to indemnify, hold harmless, exonerate and to advance expenses on behalf of, persons who serve the Company and its direct and indirect subsidiaries to the fullest extent permitted by applicable law in order to, among other things, support the retention of highly competent persons who may be hesitant to serve in such roles without such protections;

WHEREAS, this Agreement is a supplement to and in furtherance of the Company’s Amended and Restated Certificate of Incorporation (the “Charter”) and the Amended and Restated Bylaws (the “Bylaws” and together with the Charter, the “Organizational Documents”), in each case, as may be amended from time to time, and any resolutions adopted pursuant thereto, as well as any rights of Indemnitees under any directors’ and officers’ policies of liability insurance, and shall not be deemed a substitute therefor, nor to diminish or abrogate any rights of Indemnitee thereunder;

WHEREAS, Indemnitee may not be willing to serve as an officer or director without adequate protection, and the Company desires Indemnitee to serve in such capacity, and Indemnitee is willing to serve, continue to serve, and to take on additional service for or on behalf of the Company on the condition that Indemnitee be so indemnified; and

[WHEREAS, Indemnitee has certain rights to indemnification and/or insurance provided by Berkshire Partners LLC (the “Berkshire Sponsor”), which Indemnitee and the Berkshire Sponsor intend to be secondary to the primary obligation of the Company to indemnify Indemnitee as provided herein, with the Company’s acknowledgement and agreement to the foregoing being a material condition to Indemnitee’s willingness to serve on the Board.]¹

NOW, THEREFORE, in consideration of the Indemnitee’s agreement to serve as a director or officer of the Company from and after the date hereof, and the premises and the covenants contained herein, the Company and Indemnitee do hereby covenant and agree as follows:

1. Indemnity of Indemnitee. The Company hereby agrees to hold harmless and indemnify Indemnitee to the fullest extent permitted by law, as such may be amended from time to time. In furtherance of the foregoing indemnification, and without limiting the generality thereof:

(a) Proceedings Other Than Proceedings by or in the Right of the Company. Indemnitee shall be entitled to the rights of indemnification provided in this Section l(a) if, by reason of Indemnitee’s Corporate Status, Indemnitee is, or is threatened to be made, a party to or participant in any Proceeding other than a Proceeding by or in the right of the Company. Pursuant to this Section 1(a), Indemnitee shall be indemnified against all Expenses, judgments, penalties, fines and amounts paid in settlement actually and reasonably incurred by Indemnitee, or on Indemnitee’s behalf, in connection with such Proceeding or any claim, issue or matter therein, if Indemnitee acted in good faith and in a manner Indemnitee reasonably believed to be in or not opposed to the best interests of the Company, and with respect to any criminal Proceeding, had no reasonable cause to believe Indemnitee’s conduct was unlawful.

(b) Proceedings by or in the Right of the Company. Indemnitee shall be entitled to the rights of indemnification provided in this Section 1(b) if, by reason of Indemnitee’s Corporate Status, Indemnitee is, or is threatened to be made, a party to or participant in any Proceeding brought by or in the right of the Company. Pursuant to this Section 1(b), Indemnitee shall be indemnified against all Expenses actually and reasonably incurred by Indemnitee, or on Indemnitee’s behalf, in connection with such Proceeding if Indemnitee acted in good faith and in a manner Indemnitee reasonably believed to be in or not opposed to the best interests of the Company; provided, however, if applicable law so provides, no indemnification against such Expenses shall be made in respect of any claim, issue or matter in such Proceeding as to which Indemnitee shall have been adjudged to be liable to the Company unless and to the extent that the Court of Chancery of the State of Delaware shall determine that such indemnification may be made.

(c) Indemnification for Expenses of a Party Who is Wholly or Partly Successful. Without limiting any other provision of this Agreement, to the extent that Indemnitee is, by reason of Indemnitee’s Corporate Status, a party to and is successful, on the merits or otherwise, in any Proceeding, he shall be indemnified to the maximum extent permitted by law, as such may be amended from time to time, against all Expenses actually and reasonably incurred by Indemnitee or on Indemnitee’s behalf in connection therewith. If Indemnitee is not wholly successful in such Proceeding but is successful, on the merits or otherwise, as to one or more but less than all claims, issues or matters in such Proceeding, the Company shall indemnify Indemnitee against all Expenses actually and reasonably incurred by Indemnitee or on Indemnitee’s behalf in connection with each successfully resolved claim, issue or matter. For purposes of this Section 1(c) and without limitation, the termination of any claim, issue or matter in such a Proceeding by dismissal, with or without prejudice, without payment of any judgment, penalty or fine by Indemnitee, or on Indemnitee’s behalf, in connection with such claim issue or matter, shall be deemed to be a successful result as to such claim, issue or matter.

(d) Partial Indemnification. If Indemnitee is entitled under any provision of this Agreement to indemnification by the Company for some or a portion of Expenses, but not, however, for the total amount thereof, the Company shall nevertheless indemnify Indemnitee for the portion thereof to which Indemnitee is entitled.

2

2. Additional Indemnity. In addition to, and without regard to any limitations on, the indemnification provided for in Section 1 of this Agreement, the Company shall and hereby does indemnify and hold harmless Indemnitee against all Expenses, judgments, penalties, fines and amounts paid in settlement actually and reasonably incurred by Indemnitee or on Indemnitee’s behalf if, by reason of Indemnitee’s Corporate Status, Indemnitee is, or is threatened to be made, a party to or participant in any Proceeding (including a Proceeding by or in the right of the Company), including, without limitation, all liability arising out of the negligence or active or passive wrongdoing of Indemnitee. The only limitation that shall exist upon the Company’s obligations pursuant to this Agreement shall be that the Company shall not be obligated to make any payment to Indemnitee that is finally determined (under the procedures, and subject to the presumptions, set forth in Sections 6 and 7 hereof) to be unlawful.

3. Contribution.

(a) Whether or not the indemnification provided in Sections 1 and 2 hereof is available, in respect of any threatened, pending or completed action, suit or proceeding in which the Company is jointly liable with Indemnitee (or would be if joined in such action, suit or proceeding), the Company shall pay, in the first instance, the entire amount of any judgment or settlement of such action, suit or proceeding without requiring Indemnitee to contribute to such payment and the Company hereby waives and relinquishes any right of contribution it may have against Indemnitee.

(b) Without diminishing or impairing the obligations of the Company set forth in the preceding subparagraph, if, for any reason, Indemnitee shall elect or be required to pay all or any portion of any judgment or settlement in any threatened, pending or completed action, suit or proceeding in which the Company is jointly liable with Indemnitee (or would be if joined in such action, suit or proceeding), the Company shall contribute to the amount of Expenses, judgments, fines and amounts paid in settlement actually and reasonably incurred and paid or payable by Indemnitee in proportion to the relative benefits received by the Company and all officers, directors or employees of the Company, other than Indemnitee, who are jointly liable with Indemnitee (or would be if joined in such action, suit or proceeding), on the one hand, and Indemnitee, on the other hand, from the transaction from which such action, suit or proceeding arose; provided, however, that the proportion determined on the basis of relative benefit may, to the extent necessary to conform to law, be further adjusted by reference to the relative fault of the Company and all officers, directors or employees of the Company other than Indemnitee who are jointly liable with Indemnitee (or would be if joined in such action, suit or proceeding), on the one hand, and Indemnitee, on the other hand, in connection with the events that resulted in such expenses, judgments, fines or settlement amounts, as well as any other equitable considerations which the Law may require to be considered. The relative fault of the Company and all officers, directors or employees of the Company, other than Indemnitee, who are jointly liable with Indemnitee (or would be if joined in such action, suit or proceeding), on the one hand, and Indemnitee, on the other hand, shall be determined by reference to, among other things, the degree to which their actions were motivated by intent to gain personal profit or advantage, the degree to which their liability is primary or secondary and the degree to which their conduct is active or passive.

(c) The Company hereby agrees to fully indemnify and hold Indemnitee harmless from any claims of contribution that may be brought by officers, directors or employees of the Company, other than Indemnitee, who may be jointly liable with Indemnitee.

3

(d) To the fullest extent permissible under applicable law, if the indemnification provided for in this Agreement is unavailable to Indemnitee for any reason whatsoever, the Company, in lieu of indemnifying Indemnitee, shall contribute to the amount incurred by Indemnitee, whether for judgments, fines, penalties, excise taxes, amounts paid or to be paid in settlement and/or for Expenses, in connection with any claim relating to an indemnifiable event under this Agreement, in such proportion as is deemed fair and reasonable in light of all of the circumstances of such Proceeding in order to reflect (i) the relative benefits received by the Company and Indemnitee as a result of the event(s) and/or transaction(s) giving cause to such Proceeding; and/or (ii) the relative fault of the Company (and its directors, officers, employees and agents) and Indemnitee in connection with such event(s) and/or transaction(s).

4. Indemnification for Expenses of a Witness. Notwithstanding any other provision of this Agreement, to the extent that Indemnitee is, by reason of Indemnitee’s Corporate Status, a witness, or is made (or asked to) respond to discovery requests, in any Proceeding to which Indemnitee is not a party, he shall be indemnified against all Expenses actually and reasonably incurred by Indemnitee or on Indemnitee’s behalf in connection therewith.

5. Advancement of Expenses. Notwithstanding any other provision of this Agreement, the Company shall advance all Expenses incurred by or on behalf of Indemnitee in connection with any Proceeding by reason of Indemnitee’s Corporate Status within thirty (30) days after the receipt by the Company of a statement or statements from Indemnitee requesting such advance or advances from time to time, whether prior to or after final disposition of such Proceeding. Such statement or statements shall reasonably evidence the Expenses incurred by Indemnitee and shall include or be preceded or accompanied by a written undertaking by or on behalf of Indemnitee to repay any Expenses advanced if it shall ultimately be determined that Indemnitee is not entitled to be indemnified against such Expenses. Any advances and undertakings to repay pursuant to this Section 5 shall be unsecured and interest free.

6. Procedures and Presumptions for Determination of Entitlement to Indemnification. It is the intent of this Agreement to secure for Indemnitee rights of indemnity that are as favorable as may be permitted under the DGCL and public policy of the State of Delaware. Accordingly, the parties agree that the following procedures and presumptions shall apply in the event of any question as to whether Indemnitee is entitled to indemnification under this Agreement:

(a) To obtain indemnification under this Agreement, Indemnitee shall submit to the Corporate Secretary of the Company a written request, including therein or therewith such documentation and information as is reasonably available to Indemnitee and is reasonably necessary to determine whether and to what extent Indemnitee is entitled to indemnification. The Corporate Secretary of the Company shall, promptly upon receipt of such a request for indemnification, advise the Board in writing that Indemnitee has requested indemnification. Notwithstanding the foregoing, any failure of Indemnitee to provide such a request to the Company, or to provide such a request in a timely fashion, shall not relieve the Company of any liability that it may have to Indemnitee unless, and to the extent that, such failure actually and materially prejudices the interests of the Company.

4

(b) Upon written request by Indemnitee for indemnification pursuant to the first sentence of Section 6(a) hereof, a determination with respect to Indemnitee’s entitlement thereto shall be made in the specific case by one of the following four methods, which shall be at the election of the Board: (1) by a majority vote of the Disinterested Directors, even though less than a quorum, (2) by a committee of Disinterested Directors designated by a majority vote of the Disinterested Directors, even though less than a quorum, (3) if there are no Disinterested Directors, or if the Disinterested Directors so direct, by Independent Counsel in a written opinion to the Board, a copy of which shall be delivered to Indemnitee, or (4) if so directed by the Board, by the stockholders of the Company; provided, however, that if a Change in Control has occurred, the determination with respect to Indemnitee’s entitlement to indemnification shall be made by Independent Counsel.

(c) In the event the determination of entitlement to indemnification is to be made by Independent Counsel, the Independent Counsel shall be selected as provided in this Section 6(c). If a Change in Control has not occurred, the Independent Counsel shall be selected by the Board (including a vote of a majority of the Disinterested Directors, if obtainable), and the Company shall give written notice advising the Indemnitee of the identity of the Independent Counsel so selected. Indemnitee may, within 10 days after such written notice of selection shall have been given, deliver to the Company a written objection to such selection; provided, however, that such objection may be asserted only on the ground that the Independent Counsel so selected does not meet the requirements of “Independent Counsel” as defined in Section 13 of this Agreement, and the objection shall set forth with particularity the factual basis of such assertion. Absent a proper and timely objection, the person so selected shall act as Independent Counsel. If a written objection is made, the Independent Counsel selected may not serve as Independent Counsel unless and until such objection is withdrawn or a court has determined that such objection is without merit. If a Change in Control has occurred, the Independent Counsel shall be selected by the Indemnitee (unless the Indemnitee shall request that such selection be made by the Board, in which event the preceding sentence shall apply), and approved by the Board (which approval shall not be unreasonably withheld). If (i) an Independent Counsel is to make the determination of entitlement pursuant to this Section 6, and (ii) within 20 days after submission by Indemnitee of a written request for indemnification pursuant to Section 6(a) hereof, no Independent Counsel shall have been selected and not objected to, either the Company or Indemnitee may petition the Court of Chancery of the State of Delaware or other court of competent jurisdiction for resolution of any objection which shall have been made by Indemnitee to the Company’s selection of Independent Counsel and/or for the appointment as Independent Counsel of a person selected by the court or by such other person as the court shall designate, and the person with respect to whom all objections are so resolved or the person so appointed shall act as Independent Counsel under Section 6(b) hereof. The Company shall pay any and all reasonable fees and expenses of Independent Counsel incurred by such Independent Counsel in connection with acting pursuant to Section 6(b) hereof, and the Company shall pay all reasonable fees and expenses incident to the procedures of this Section 6(c), regardless of the manner in which such Independent Counsel was selected or appointed.

5

(d) In making a determination with respect to entitlement to indemnification hereunder, the person or persons or entity making such determination shall presume that Indemnitee is entitled to indemnification under this Agreement. Anyone seeking to overcome this presumption shall have the burden of proof and the burden of persuasion by clear and convincing evidence. Neither the failure of the Company (including by its directors or independent legal counsel) to have made a determination prior to the commencement of any action pursuant to this Agreement that indemnification is proper in the circumstances because Indemnitee has met the applicable standard of conduct, nor an actual determination by the Company (including by its directors or independent legal counsel) that Indemnitee has not met such applicable standard of conduct, shall be a defense to the action or create a presumption that Indemnitee has not met the applicable standard of conduct.

(e) Indemnitee shall be deemed to have acted in good faith if Indemnitee’s action is based on the records or books of account of the Enterprise, including financial statements, or on information supplied to Indemnitee by the officers of the Enterprise in the course of their duties, or on the advice of legal counsel for the Enterprise or on information or records given or reports made to the Enterprise by an independent certified public accountant or by an appraiser or other expert selected with reasonable care by the Enterprise. The provisions of this Section 6(e) shall not be deemed to be exclusive or to limit in any way the other circumstances in which the Indemnitee may be deemed to have met the applicable standard of conduct set forth in this Agreement. In addition, the knowledge and/or actions, or failure to act, of any director, officer, agent or employee of the Enterprise shall not be imputed to Indemnitee for purposes of determining the right to indemnification under this Agreement. Whether or not the foregoing provisions of this Section 6(e) are satisfied, it shall in any event be presumed that Indemnitee has at all times acted in good faith and in a manner he reasonably believed to be in or not opposed to the best interests of the Company. Anyone seeking to overcome this presumption shall have the burden of proof and the burden of persuasion by clear and convincing evidence.

(f) If the person, persons or entity empowered or selected under this Section 6 to determine whether Indemnitee is entitled to indemnification shall not have made a determination within sixty (60) days after receipt by the Company of the request therefor, the requisite determination of entitlement to indemnification shall be deemed to have been made and Indemnitee shall be entitled to such indemnification absent (i) a misstatement by Indemnitee of a material fact, or an omission of a material fact necessary to make Indemnitee’s statement not materially misleading, in connection with the request for indemnification, or (ii) a prohibition of such indemnification under applicable law; provided, however, that such 60-day period may be extended for a reasonable time, not to exceed an additional thirty (30) days, if the person, persons or entity making such determination with respect to entitlement to indemnification in good faith requires such additional time to obtain or evaluate documentation and/or information relating thereto; and provided, further, that the foregoing provisions of this Section 6(f) shall not apply if the determination of entitlement to indemnification is to be made by the stockholders pursuant to Section 6(b) of this Agreement and if (A) within fifteen (15) days after receipt by the Company of the request for such determination, the Board or the Disinterested Directors, if appropriate, resolve to submit such determination to the stockholders for their consideration at an annual meeting thereof to be held within seventy-five (75) days after such receipt and such determination is made thereat, or (B) a special meeting of stockholders is called within fifteen (15) days after such receipt for the purpose of making such determination, such meeting is held for such purpose within sixty (60) days after having been so called and such determination is made thereat.

6

(g) Indemnitee shall cooperate with the person, persons or entity making such determination with respect to Indemnitee’s entitlement to indemnification, including providing to such person, persons or entity upon reasonable advance request any documentation or information, which is not privileged or otherwise protected from disclosure and which is reasonably available to Indemnitee and reasonably necessary to such determination. Any Independent Counsel, member of the Board or stockholder of the Company shall act reasonably and in good faith in making a determination regarding Indemnitee’s entitlement to indemnification under this Agreement. Any costs or expenses (including attorneys’ fees and disbursements) incurred by Indemnitee in so cooperating with the person, persons or entity making such determination shall be borne by the Company (irrespective of the determination as to Indemnitee’s entitlement to indemnification) and the Company hereby indemnifies and agrees to hold Indemnitee harmless therefrom.

(h) The Company acknowledges that a settlement or other disposition short of final judgment may be successful if it permits a party to avoid expense, delay, distraction, disruption and uncertainty. In the event that any action, claim or proceeding to which Indemnitee is a party is resolved in any manner other than by adverse judgment against Indemnitee (including, without limitation, settlement of such action, claim or proceeding with or without payment of money or other consideration) it shall be presumed that Indemnitee has been successful on the merits or otherwise in such action, suit or proceeding. Anyone seeking to overcome this presumption shall have the burden of proof and the burden of persuasion by clear and convincing evidence.

(i) The termination of any Proceeding or of any claim, issue or matter therein, by judgment, order, settlement or conviction, or upon a plea of nolo contendere or its equivalent, shall not (except as otherwise expressly provided in this Agreement) of itself adversely affect the right of Indemnitee to indemnification or create a presumption that Indemnitee did not act in good faith and in a manner which he reasonably believed to be in or not opposed to the best interests of the Company or, with respect to any criminal Proceeding, that Indemnitee had reasonable cause to believe that Indemnitee’s conduct was unlawful.

7. Remedies of Indemnitee.

(a) In the event that (i) a determination is made pursuant to Section 6 of this Agreement that Indemnitee is not entitled to indemnification under this Agreement, (ii) advancement of Expenses is not timely made pursuant to Section 5 of this Agreement, (iii) no determination of entitlement to indemnification is made pursuant to Section 6(b) of this Agreement within 90 days after receipt by the Company of the request for indemnification, (iv) payment of indemnification is not made pursuant to this Agreement within ten (10) days after receipt by the Company of a written request therefor or (v) payment of indemnification is not made within ten (10) days after a determination has been made that Indemnitee is entitled to indemnification or such determination is deemed to have been made pursuant to Section 6 of this Agreement, Indemnitee shall be entitled to an adjudication in an appropriate court of the State of Delaware, or in any other court of competent jurisdiction, of Indemnitee’s entitlement to such indemnification, contribution or advancement of Expenses. Alternatively, Indemnitee, at such person’s option, may seek an award in arbitration to be conducted by a single arbitrator pursuant to the Commercial Arbitration Rules of the American Arbitration Association. Except as set forth herein, the provisions of Delaware law (without regard to its conflict of law rules) shall apply to any such arbitration. The Company shall not oppose Indemnitee’s right to seek any such adjudication or award in arbitration.

7

(b) In the event that a determination shall have been made pursuant to Section 6(b) of this Agreement that Indemnitee is not entitled to indemnification, any judicial proceeding commenced pursuant to this Section 7 shall be conducted in all respects as a de novo trial, or arbitration, on the merits, and Indemnitee shall not be prejudiced by reason of the adverse determination under Section 6(b). In any judicial proceeding or arbitration commenced pursuant to this Section 7, Indemnitee shall be presumed to be entitled to indemnification under this Agreement and the Company shall have the burden of proving Indemnitee is not entitled to indemnification or advancement of Expenses, as the case may be, and the Company may not refer to or introduce into evidence any determination pursuant to Section 6(b) of this Agreement adverse to Indemnitee for any purpose. If Indemnitee commences a judicial proceeding or arbitration pursuant to this Section 7, Indemnitee shall not be required to reimburse the Company for any advances pursuant to Section 5 until a final determination is made with respect to Indemnitee’s entitlement to indemnification (as to which all rights of appeal have been exhausted or lapsed).

(c) If a determination shall have been made pursuant to Section 6(b) of this Agreement that Indemnitee is entitled to indemnification, the Company shall be bound by such determination in any judicial proceeding commenced pursuant to this Section 7, absent (i) a misstatement by Indemnitee of a material fact, or an omission of a material fact necessary to make Indemnitee’s misstatement not materially misleading in connection with the application for indemnification, or (ii) a prohibition of such indemnification under applicable law.

(d) In the event that Indemnitee, pursuant to this Section 7, seeks a judicial adjudication of Indemnitee’s rights under, or to recover damages for breach of, this Agreement, or to recover under any directors’ and officers’ liability insurance policies maintained by the Company, the Company shall pay on Indemnitee’s behalf, in advance, any and all expenses (of the types described in the definition of Expenses in Section 13 of this Agreement) actually and reasonably incurred by Indemnitee in such judicial adjudication, regardless of whether Indemnitee ultimately is determined to be entitled to such indemnification, advancement of expenses or insurance recovery.

(e) The Company shall be precluded from asserting in any judicial proceeding commenced pursuant to this Section 7 that the procedures and presumptions of this Agreement are not valid, binding and enforceable and shall stipulate in any such court that the Company is bound by all the provisions of this Agreement. It is the intent of the Company that, to the fullest extent permitted by law, the Indemnitee not be required to incur legal fees or other Expenses associated with the interpretation, enforcement or defense of Indemnitee’s rights under this Agreement by litigation or otherwise because the cost and expense thereof would substantially detract from the benefits intended to be extended to the Indemnitee hereunder. The Company shall indemnify Indemnitee against any and all Expenses and, if requested by Indemnitee, shall (within ten (10) days after receipt by the Company of a written request therefore) advance, to the extent not prohibited by law, such expenses to Indemnitee, which are incurred by Indemnitee in connection with any action brought by Indemnitee for indemnification or advance of Expenses from the Company under this Agreement or under any directors’ and officers’ liability insurance policies maintained by the Company, regardless of whether Indemnitee ultimately is determined to be entitled to such indemnification, advancement of Expenses or insurance recovery, as the case may be.

8

(f) Notwithstanding anything in this Agreement to the contrary, no determination as to entitlement to indemnification under this Agreement shall be required to be made prior to the final disposition of the Proceeding.

8. Non-Exclusivity; Survival of Rights; Insurance; Primacy of Indemnification; Subrogation.

(a) The rights of indemnification and to receive advancement of expenses as provided by this Agreement shall not be deemed exclusive of any other rights to which Indemnitee may at any time be entitled under applicable law, the Organizational Documents, any agreement, a vote of stockholders, a resolution of directors or otherwise, of the Company. No amendment, alteration or repeal of this Agreement or of any provision hereof shall limit or restrict any right of Indemnitee under this Agreement in respect of any action taken or omitted by such Indemnitee in such person’s Corporate Status prior to such amendment, alteration or repeal. To the extent that a change in the DGCL, whether by statute or judicial decision, permits greater indemnification than would be afforded currently under the Organizational Documents and this Agreement, it is the intent of the parties hereto that Indemnitee shall enjoy by this Agreement the greater benefits so afforded by such change. No right or remedy herein conferred is intended to be exclusive of any other right or remedy, and every other right and remedy shall be cumulative and in addition to every other right and remedy given hereunder or now or hereafter existing at law or in equity or otherwise. The assertion or employment of any right or remedy hereunder, or otherwise, shall not prevent the concurrent assertion or employment of any other right or remedy.

(b) The Company shall obtain and maintain in effect during the entire period for which the Company is obligated to indemnify Indemnitee under this Agreement, one or more policies of insurance with one or more reputable insurance companies to provide the directors and officers of the Company with coverage for losses from wrongful acts and omissions and to ensure the Company’s performance of its indemnification obligations under this Agreement. Indemnitee shall be covered by such policy or policies in accordance with its or their terms to the maximum extent of the coverage available for any such director or officer under such policy or policies. In all such insurance policies, Indemnitee shall be named as an insured in such a manner as to provide Indemnitee with the same rights and benefits as are accorded to the most favorably insured of the Company’s directors and officers. At the time of the receipt of a notice of a claim pursuant to the terms hereof, the Company shall give prompt notice of the commencement of such proceeding to the insurers in accordance with the procedures set forth in the respective policies. The Company shall thereafter take all necessary or desirable action to cause such insurers to pay, on behalf of Indemnitee, all amounts payable as a result of such proceeding in accordance with the terms of such policies.

9

(c) [The Company hereby acknowledges that Indemnitee has certain rights to indemnification, advancement of expenses and/or insurance provided by the Berkshire Sponsor and certain affiliates that, directly or indirectly, (i) are controlled by, (ii) control or (iii) are under common control with, the Berkshire Sponsor (collectively, the “Fund Indemnitors”). The Company hereby agrees (i) that it is the indemnitor of first resort (i.e., its obligations to Indemnitee are primary and any obligation of the Fund Indemnitors to advance expenses or to provide indemnification for the same expenses or liabilities incurred by Indemnitee are secondary), (ii) that it shall be required to advance the full amount of expenses incurred by Indemnitee and shall be liable for the full amount of all Expenses, judgments, penalties, fines and amounts paid in settlement to the extent legally permitted and as required by the terms of this Agreement and the Certificate of Incorporation or By-laws of the Company (or any other agreement between the Company and Indemnitee), without regard to any rights Indemnitee may have against the Fund Indemnitors, and, (iii) that it irrevocably waives, relinquishes and releases the Fund Indemnitors from any and all claims against the Fund Indemnitors for contribution, subrogation or any other recovery of any kind in respect thereof. The Company further agrees that no advancement or payment by the Fund Indemnitors on behalf of Indemnitee with respect to any claim for which Indemnitee has sought indemnification from the Company shall affect the foregoing and the Fund Indemnitors shall have a right of contribution and/or be subrogated to the extent of such advancement or payment to all of the rights of recovery of Indemnitee against the Company. The Company and Indemnitee agree that the Fund Indemnitors are express third party beneficiaries of the terms of this Section 8(d).]²

(d) [Except as provided in Section 8(c) above, i][I]n the event of any payment under this Agreement, the Company shall be subrogated to the extent of such payment to all of the rights of recovery of Indemnitee [(other than against the Fund Indemnitors)], who shall execute all papers required and take all action necessary to secure such rights, including execution of such documents as are necessary to enable the Company to bring suit to enforce such rights.

(e) [Except as provided in Section 8(c) above, t][T]he Company shall not be liable under this Agreement to make any payment of amounts otherwise indemnifiable hereunder if and to the extent that Indemnitee has otherwise actually received such payment under any insurance policy, contract, agreement or otherwise.

(d) in connection with any Proceeding (or any part of any Proceeding) initiated by Indemnitee, including any Proceeding (or any part of any Proceeding) initiated by Indemnitee against the Company or its directors, officers, employees or other indemnitees, unless (i) the Company has joined in or the Board authorized the Proceeding (or any part of any Proceeding) prior to its initiation, (ii) the Company provides the indemnification, in its sole discretion, pursuant to the powers vested in the Company under applicable law, or (iii) the Proceeding is one to enforce Indemnitee’s rights under this Agreement.

Without limiting the generality of the foregoing, this Agreement is intended to confer upon Indemnitee indemnification rights to the fullest extent permitted by applicable laws.

14

15. Enforcement and Binding Effect.

(a) The Company expressly confirms and agrees that it has entered into this Agreement and assumed the obligations imposed on it hereby in order to induce Indemnitee to serve as a director or officer of the Company, and the Company acknowledges that Indemnitee is relying upon this Agreement in serving in such capacity.

(b) Without limiting any of the rights of Indemnitee under the Charter or By-laws of the Company as they may be amended from time to time, this Agreement constitutes the entire agreement between the parties hereto with respect to the subject matter hereof and supersedes all prior agreements and understandings, oral, written and implied, between the parties hereto with respect to the subject matter hereof.

(c) The indemnification and advancement of expenses provided by, or granted pursuant to this Agreement shall be binding upon and be enforceable by the parties hereto and their respective successors and assigns (including any direct or indirect successor by purchase, merger, consolidation or otherwise to all or substantially all of the business or assets of the Company), shall continue as to an Indemnitee who has ceased to be a director, officer, employee or agent of the Company or of any other Enterprise at the Company’s request, and shall inure to the benefit of Indemnitee and such person’s spouse, assigns, heirs, devisees, executors and administrators and other legal representatives.

(d) The Company shall require and cause any successor (whether direct or indirect by purchase, merger, consolidation or otherwise) to all, substantially all or a substantial part, of the business and/or assets of the Company to expressly to assume and agree to perform this Agreement in the same manner and to the same extent that the Company would be required to perform if no such succession had taken place.

(e) The Company and Indemnitee agree herein that a monetary remedy for breach of this Agreement, at some later date, may be inadequate, impracticable and difficult of proof, and further agree that such breach may cause Indemnitee irreparable harm. Accordingly, the parties hereto agree that Indemnitee may enforce this Agreement by seeking injunctive relief and/or specific performance hereof, without any necessity of showing actual damage or irreparable harm and that by seeking injunctive relief and/or specific performance, Indemnitee shall not be precluded from seeking or obtaining any other relief to which he may be entitled. The Company and Indemnitee further agree that Indemnitee shall be entitled to such specific performance and injunctive relief, including temporary restraining orders, preliminary injunctions and permanent injunctions, without the necessity of posting bonds or other undertaking in connection therewith. The Company acknowledges that in the absence of a waiver, a bond or undertaking may be required of Indemnitee by the Court, and the Company hereby waives any such requirement of such a bond or undertaking.

16. Modification and Waiver. No supplement, modification, termination or amendment of this Agreement shall be binding unless executed in writing by both of the parties hereto. No waiver of any of the provisions of this Agreement shall be deemed or shall constitute a waiver of any other provisions hereof (whether or not similar) nor shall such waiver constitute a continuing waiver.

15

17. Notice by Indemnitee. Indemnitee agrees promptly to notify the Company in writing upon being served with or otherwise receiving any summons, citation, subpoena, complaint, indictment, information or other document relating to any Proceeding or matter which may be subject to indemnification covered hereunder. The failure to so notify the Company shall not relieve the Company of any obligation which it may have to Indemnitee under this Agreement or otherwise.

18. Notices. All notices and other communications given or made pursuant to this Agreement shall be in writing and shall be deemed effectively given: (a) upon personal delivery to the party to be notified, (b) when sent by confirmed electronic mail or facsimile if sent during normal business hours of the recipient, and if not so confirmed, then on the next business day, (c) five (5) days after having been sent by registered or certified mail, return receipt requested, postage prepaid, or (d) one (1) day after deposit with a nationally recognized overnight courier, specifying next day delivery, with written verification of receipt.

ARTICLE I

DEFINITIONS

Section 1.1 Definitions. As used in this Agreement, the terms set forth in this Article I shall have the following meanings (such meanings to be equally applicable to both the singular and plural forms of the terms defined).

“Acquired Units” means the Units acquired by the Corporate Taxpayer in the Reorganization.

“Actual Tax Liability” means, with respect to any Taxable Year, the sum of (i) (A) the liability for U.S. federal income Taxes of the Corporate Taxpayer as reported on its IRS Form 1120 (or any successor form) for such taxable year, or, if applicable, determined in accordance with a Determination (and if applicable, in accordance with Section 2.4(b)), plus (B) without duplication, the portion of any liability for U.S. federal income Taxes imposed directly on OpCo (and OpCo’s applicable subsidiaries) under Section 6225 or any similar provision of the Code that is allocable to the Corporate Taxpayer under Section 704 of the Code, and (ii) the product of the amount of the U.S. federal taxable income for such taxable year reported on the Corporate Taxpayer’s IRS Form 1120 (or any successor form) (or, if applicable, determined in accordance with a Determination) and the Assumed State and Local Tax Rate.

2

“Affiliate” means, with respect to any Person, any other Person that directly or indirectly, through one or more intermediaries, Controls, is Controlled by, or is under common Control with, such first Person.

“Agreed Rate” means a per annum rate of LIBOR plus 100 basis points.

“Agreement” has the meaning set forth in the Preamble to this Agreement.

“Alternate Source” has the meaning set forth in the definition of “LIBOR.”

“Amended Schedule” has the meaning set forth in Section 2.4(b) of this Agreement.

“Assumed State and Local Tax Rate” means the Tax rate equal to the sum of the products of (x) the Corporate Taxpayer’s income and franchise tax apportionment factor for each state and local jurisdiction in which the Corporate Taxpayer files income or franchise Tax Returns for the relevant Taxable Year and (y) the highest corporate income and franchise Tax rate(s) for each such state and local jurisdiction in which the Corporate Taxpayer files income or franchise Tax Returns for each relevant Taxable Year. As an illustration of the calculation of the Assumed State and Local Tax Rate for a Taxable Year, if the Corporate Taxpayer solely files Tax Returns in State 1 and State 2 in a Taxable Year, the maximum applicable corporate Tax rates in effect in such states in such Taxable Year are 6.5% and 5.5%, respectively, and the apportionment factors for such states in such Taxable Year are 55% and 45% respectively, then the Assumed State and Local Tax Rate for such Taxable Year is equal to 6.05% (i.e., 6.5% multiplied by 55% plus 5.5% multiplied by 45%).

“Attributable” means the portion of any Tax Attribute of the Corporate Taxpayer that is “Attributable” to the Blocker Shareholders or to any present or former Unit Holder, as the case may be, determined under the following principles:

(i) any Blocker Attributes shall be determined separately with respect to each Blocker based on the Blocker Attributes attributable to such Blocker at the time of the Reorganization and are Attributable to the Blocker Shareholders of each Blocker to which such Blocker Attributes relate in proportion to each Blocker Shareholder’s interest in such Blocker prior to the Reorganization;

(ii) any Blocker Transferred Basis shall be determined separately with respect to each Blocker based on the Blocker Transferred Basis associated with the Units that were acquired as a result of the participation of such Blocker in the Reorganization and is Attributable to the Blocker Shareholders of each Blocker to which such Blocker Transferred Basis relates in proportion to each Blocker Shareholder’s interest in such Blocker prior to the Reorganization;

(iii) any IPO Basis shall be determined separately with respect to each Blocker Shareholder and Unit Holder and is Attributable to each Blocker Shareholder or Unit Holder, as applicable, in an amount equal to the product of the total IPO Basis and the IPO Basis Percentage of such Blocker Shareholder or Unit Holder, as applicable;

3

(iv) any Exchange Basis shall be determined separately with respect to each Exchanging Holder and is Attributable to each Exchanging Holder in an amount equal to the Exchange Basis associated with the Units transferred upon an Exchange;

(v) the Basis Adjustments shall be determined separately with respect to each Exchanging Holder, using reasonable methods for tracking such Basis Adjustments, and are Attributable to each Exchanging Holder in an amount equal to the total Basis Adjustment relating to such Units delivered to the Corporate Taxpayer by such Exchanging Holder in the Exchange (for the avoidance of doubt, with respect to any Basis Adjustments attributable to a distribution or redemption, the Exchanging Holder shall be the Unit Holder relinquishing its interest in the Reference Asset); and

(vi) any deduction to the Corporate Taxpayer with respect to a Taxable Year in respect of Imputed Interest is Attributable to the Person that is required to include the Imputed Interest in income, determined as if it were a U.S. person generally subject to U.S. federal income tax (without regard to whether such Person is actually subject to Tax thereon).

“Attribute Schedule” has the meaning set forth in Section 2.2 of this Agreement.

“Basis Adjustment” means the adjustment to the Tax basis of a Reference Asset including under Sections 732, 734(b), 707(a), 737 and/or 1012 of the Code (in situations where, as a result of one or more Exchanges, OpCo becomes an entity that is disregarded as separate from its owner for U.S. federal income tax purposes) or under Sections 734(b), 743(b) and/or 754 of the Code (in situations where, following an Exchange, OpCo remains in existence as an entity treated as a partnership for U.S. federal income tax purposes) , as a result of an Exchange and the payments made pursuant to this Agreement in respect of such Exchange. For the avoidance of doubt, the amount of any Basis Adjustment resulting from an Exchange of one or more Units shall be determined without regard to any Pre-Exchange Transfer of such Units and as if any such Pre-Exchange Transfer had not occurred. The amount of any Basis Adjustment shall be determined using the Market Value at the time of the Exchange.

“Beneficial Owner” means, with respect to any security, a Person who directly or indirectly, through any contract, arrangement, understanding, relationship or otherwise, has or shares: (i) voting power, which includes the power to vote, or to direct the voting of, such security; and/or (ii) investment power, which includes the power to dispose of, or to direct the disposition of, such security. The term “Beneficial Ownership” shall have a correlative meaning.

“Berkshire Blocker” means PHD Berkshire Fund VIII-A Blocker Corporation, a Delaware corporation.

Notwithstanding the foregoing, the term “Blocker Attribute” shall not include any Tax attribute of a Blocker that is used to offset Taxes of such Blocker, if such offset Taxes are attributable to taxable periods (or portion thereof) ending on or prior to the date of the Reorganization.

“Blocker Shareholder” means, a Person who, after the GP Contribution and immediately prior to the Reorganization, holds equity interests of a Blocker, and as a result of the Reorganization, holds Class A Shares.

“Blocker Transferred Basis” means, with respect to a Blocker Shareholder, the share of Tax basis of the Reference Assets that are amortizable under Section 197 of the Code or that are otherwise reported as amortizable on IRS Form 4562 for U.S. federal income tax purposes associated with the Acquired Units of such Blocker acquired by the Corporate Taxpayer in the Reorganization, determined as of the time of the Reorganization; provided, that any Tax basis included in the IPO Basis Attributable to the Blockers (with respect to Acquired Units) or included in Blocker Attributes shall be excluded from the determination of the Blocker Transferred Basis.

thereon) attributable to the Exchange Basis or Basis Adjustments (other than Basis Adjustments resulting from Tax Benefit Payments attributable to the IPO Basis) will be treated as subsequent upward purchase price adjustments with respect to the Units exchanged in the applicable Exchange that have the effect of creating additional Basis Adjustments to Reference Assets for the Corporate Taxpayer in the year of payment, (D) all Tax Benefit Payments (other than Imputed Interest thereon) attributable to the IPO Basis Attributable to an Exchanging Holder will be treated as subsequent upward purchase price adjustments with respect to the Threshold Exchange Units that have the effect of creating additional Basis Adjustments to Reference Assets for the Corporate Taxpayer in the year of payment, (E) as a result, any additional Basis Adjustments will be incorporated into the current year calculation and into future year calculations, as appropriate, and (F) the Actual Tax Liability will take into account the deduction of the portion of the Tax Benefit Payment that must be accounted for as Imputed Interest.

(ii) Applicable Principles of Section 734(b) Exchanges. Notwithstanding any provisions to the contrary in this Agreement, the foregoing treatment set out in Section 2.3(b)(i) shall not be required to apply to payments hereunder to an Exchanging Holder in respect of a Section 734(b) Exchange by such Exchanging Holder. For the avoidance of doubt, payments made under this Agreement relating to a Section 734(b) Exchange shall not be treated as resulting in a Basis Adjustment to the extent such payments are treated as Imputed Interest. The parties intend that (A) an Exchanging Holder that has made a Section 734(b) Exchange shall, with respect to the Basis Adjustment resulting from such Section 734(b) Exchange or any payments hereunder in respect of such Section 734(b) Exchange, be entitled to Tax Benefit Payments attributable to such Basis Adjustments only to the extent such Basis Adjustments are allocable to the Corporate Taxpayer following such Section 734(b) Exchange (without taking into account any concurrent or subsequent Exchanges) and (B) if, as a result of a subsequent Exchange, an increased portion of the Basis Adjustments resulting from such Section 734(b) Exchange or any payments hereunder in respect of such Section 734(b) Exchange becomes allocable to the Corporate Taxpayer, then the Unit Holder that makes such subsequent Exchange shall be entitled to a Tax Benefit Payment calculated in respect of such increased portion. For purposes of this Agreement, such Basis Adjustments allocable to the Corporate Taxpayer as a result of subsequent Exchanges as described in (B) in the previous sentence shall be reported and treated like Exchange Basis for purposes of this Agreement, but for the avoidance of doubt, may include adjustments to assets that are not amortizable as provided in the definition of Exchange Basis.

(iii) Applicable Principles for Adjustments under Section 743(b). Any adjustments to tax basis occurring pursuant to section 743(b) shall also refer to any new section 743(b) adjustments with respect to the same Units that occur in tax-deferred transactions.

Section 2.4 Procedures, Amendments.

(a) Procedure. Every time PubCo delivers to a TRA Party an applicable Schedule under this Agreement, including any Amended Schedule, PubCo shall also (x) deliver to such TRA Party supporting schedules and work papers, as determined by PubCo or as reasonably requested by such TRA Party, providing reasonable detail regarding data and calculations that were relevant for purposes of preparing such Schedule and (y) allow such TRA Party reasonable access at no cost to the appropriate representatives at PubCo, as determined by PubCo or as reasonably requested by such TRA Party, in connection with a review of such Schedule. Without limiting the

17

generality of the preceding sentence, PubCo shall ensure that any Tax Benefit Schedule that is delivered to a TRA Party, along with any supporting schedules and work papers, provides a reasonably detailed presentation of the calculation of the Actual Tax Liability (the “with” calculation) and the Hypothetical Tax Liability (the “without” calculation) and identifies any material assumptions or operating procedures or principles that were used for purposes of such calculations. An applicable Schedule or amendment thereto shall become final and binding on all parties thirty (30) calendar days from the date on which all relevant TRA Parties are treated as having received the applicable Schedule or amendment thereto under Section 7.1 unless the TRA Party Representative (i) within thirty (30) calendar days from such date provides PubCo with written notice of a material objection to such Schedule (“Objection Notice”) made in good faith or (ii) provides a written waiver of such right of any Objection Notice within the period described in clause (i) above, in which case such Schedule or amendment thereto becomes binding on the date the waiver is received by PubCo. If PubCo and the TRA Party Representative, for any reason, are unable to successfully resolve the issues raised in the Objection Notice within thirty (30) calendar days after receipt by PubCo of an Objection Notice, PubCo and the TRA Party Representative shall employ the reconciliation procedures as described in Section 7.9 of this Agreement (the “Reconciliation Procedures”).

(b) Amended Schedule. The applicable Schedule for any Taxable Year shall be amended from time to time by PubCo (i) in connection with a Determination affecting such Schedule, (ii) to correct inaccuracies in the Schedule identified as a result of the receipt of additional factual information relating to a Taxable Year after the date the Schedule was provided to a TRA Party, (iii) to comply with an Expert’s determination under the Reconciliation Procedures, (iv) to reflect a change in the Realized Tax Benefit, or the Realized Tax Detriment for such Taxable Year attributable to a carryback or carryforward of a loss or other Tax item to such Taxable Year, (v) to reflect a change in the Realized Tax Benefit or the Realized Tax Detriment for such Taxable Year attributable to an amended Tax Return filed for such Taxable Year or (vi) to adjust an applicable TRA Party’s Attribute Schedule to take into account payments made pursuant to this Agreement (any such Schedule, an “Amended Schedule”). PubCo shall provide an Amended Schedule to each TRA Party when PubCo delivers the Attribute Schedule for the following taxable year.

ARTICLE III

TAX BENEFIT PAYMENTS

Section 3.1 Payments.

(a) Payments. Within five (5) calendar days after a Tax Benefit Schedule delivered to a TRA Party becomes final in accordance with Section 2.4(a) and Section 7.9, if applicable, PubCo shall pay such TRA Party for such Taxable Year the Tax Benefit Payment determined pursuant to Section 3.1(b) that is in respect of the Tax Attributes Attributable to the relevant TRA Party. Each such Tax Benefit Payment shall be made by wire transfer of immediately available funds to the bank account previously designated by such TRA Party to PubCo or as otherwise agreed by PubCo and such TRA Party. For the avoidance of doubt, (x) no Tax Benefit Payment shall be made in respect of estimated Tax payments, including, without limitation, U.S. federal estimated income Tax payments and (y) the payments provided for pursuant to the above sentence shall be computed separately for each TRA Party.

18

(b) A “Tax Benefit Payment” in respect of a TRA Party for a Taxable Year means an amount, not less than zero, equal to the Net Tax Benefit that is Attributable to such TRA Party and the Interest Amount with respect thereto. For the avoidance of doubt, for Tax purposes, the Interest Amount shall not be treated as interest, but instead, shall be treated as additional consideration in the applicable transaction, unless otherwise required by law. Subject to Section 3.3, the “Net Tax Benefit” for a Taxable Year shall be an amount equal to the excess, if any, of 85% of the Cumulative Net Realized Tax Benefit as of the end of such Taxable Year, over the total amount of payments previously made under the first sentence of Section 3.1(a) (excluding payments attributable to Interest Amounts); provided, for the avoidance of doubt, that no such recipient shall be required to return any portion of any previously made Tax Benefit Payment. The “Interest Amount” shall equal the interest on the Net Tax Benefit calculated at the Agreed Rate from the due date (without extensions) for filing IRS Form 1120 (or any successor form) of the Corporate Taxpayer with respect to Taxes for such Taxable Year until the payment date under Section 3.1(a).

(c) Maximum Payments. Notwithstanding anything to the contrary in this Agreement, with respect to the Reorganization, Initial Sales of Units and each other Exchange by or with respect to any TRA Party, if such TRA Party notifies PubCo in writing of a stated maximum selling price (within the meaning of Treasury Regulations Section 15A.453-1(c)(2)), then the amount of the consideration received in connection with the Reorganization, Initial Sales of Units or any other such Exchange and the aggregate Tax Benefit Payments to such TRA Party in respect of the Reorganization, Initial Sales of Units or any other such Exchange (other than amounts accounted for as interest under the Code) shall not exceed such stated maximum selling price.

Section 3.2 No Duplicative Payments. It is intended that the provisions of this Agreement will not result in duplicative payment of any amount (including interest) required under this Agreement. The provisions of this Agreement shall be construed in the appropriate manner to ensure such intentions are realized.

Section 3.3 Pro Rata Payments; Late Payments; Excess Payments.

(a) Pro Rata Payments. Notwithstanding anything in Section 3.1 to the contrary, to the extent that the aggregate Realized Tax Benefit of the Corporate Taxpayer with respect to the Tax Attributes is limited in a particular Taxable Year because the Corporate Taxpayer does not have sufficient taxable income, the Net Tax Benefit for that Taxable Year shall be allocated among all parties then-eligible to receive Tax Benefit Payments under this Agreement in proportion to the amounts of Net Tax Benefit for that Taxable Year, respectively, that would have been Attributable to each TRA Party if the Corporate Taxpayer had sufficient taxable income so that there were no such limitation. For the avoidance of doubt, the determination of whether Tax Benefit Payments are held-back pursuant to Section 3.4, shall not be relevant in the determination of whether a Net Tax Benefit is eligible to be allocated to the relevant TRA Party for purposes of this Section 3.3. To the extent any part of the limitation on the Realized Tax Benefit is allocated in a manner that differs from the order prescribed in the applicable rules of the Code and the Treasury Regulations regarding the utilization, or deemed utilization, of such Tax items, appropriate adjustments, consistent with the principles of this Section 3.3, shall be made in future Taxable Years to take into account such differing allocation.

19

(b) Late Payments. If for any reason the Corporate Taxpayer does not fully satisfy its payment obligations to make all Tax Benefit Payments due under this Agreement in respect of a particular Taxable Year, then the Corporate Taxpayer and the TRA Parties agree that (i) the Tax Benefit Payments for such Taxable Year shall be allocated to all parties eligible to receive Tax Benefit Payments under this Agreement in such Taxable Year in proportion to the amounts of Tax Benefit Payments, respectively, that would have been made to each TRA Party if the Corporate Taxpayer had sufficient cash available to make such Tax Benefit Payments and (ii) no Tax Benefit Payment shall be made in respect of any Taxable Year until all Tax Benefit Payments to all TRA Parties in respect of all prior Taxable Years have been made in full; provided, however, that any payments that were not made by the Corporate Taxpayer to a TRA Party as a result of the operation of Section 3.4 but have since become due and payable pursuant to Section 3.4 shall be made prior to any other Tax Benefit Payments.

(c) Excess Payments. To the extent the Corporate Taxpayer makes a payment to a TRA Party in respect of a particular Taxable Year under Section 3.1(a) of this Agreement (taking into account Section 3.3(a) and (b)) in an amount in excess of the amount of such payment that should have been made to such TRA Party in respect of such Taxable Year, then (a) such TRA Party shall not receive further payments under Section 3.1(a) until such TRA Party has foregone an amount of payments equal to such excess and (b) the Corporate Taxpayer will pay the amount of such TRA Party’s foregone payments to the other Persons to whom a payment is due under this Agreement in a manner such that each such Person to whom a payment is due under this Agreement, to the maximum extent possible, receives aggregate payments under Section 3.1(a) (taking into account Section 3.3(a) and (b)) in the amount it would have received if there had been no excess payment to such TRA Party.

Section 3.4 IPO Basis. Notwithstanding anything to the contrary herein, any and all Tax Benefit Payments that would otherwise be made pursuant to this Agreement with respect to any IPO Basis shall not be payable to the applicable TRA Party until such time as such TRA Party has exchanged Units in one or more Exchanges equal to more than [5]% of the Units held by such TRA Party determined prior to the Reorganization (such Units, with respect to each TRA Party, such TRA Party’s “Threshold Exchange Units”). Promptly following the time any such TRA Party has exchanged, in the aggregate, a number of Units equal to or exceeding the Threshold Exchange Units, such amount shall be paid by PubCo to the applicable TRA Party. Notwithstanding anything herein to the contrary, all Blocker Shareholders (with respect to the Acquired Units) shall be deemed to have exchanged any Threshold Exchange Units held by such Blocker Shareholders in the Reorganization, and, therefore, no amounts shall be held back pursuant to this Section 3.4.

20

ARTICLE IV

TERMINATION

Section 4.1 Early Termination of Agreement; Breach of Agreement.

(a) PubCo may terminate this Agreement with respect to all amounts payable to the TRA Parties and with respect to all of the Units held by the TRA Parties at any time by simultaneously paying to each TRA Party the Early Termination Payment in respect of such TRA Party; provided, however, that this Agreement shall only terminate upon the receipt of the Early Termination Payment by all TRA Parties, and provided, further, that PubCo may withdraw any notice to execute its termination rights under this Section 4.1(a) prior to the time at which any Early Termination Payment has been paid. Upon payment of the Early Termination Payment in respect of each TRA Party by PubCo, PubCo shall have no further payment obligations under this Agreement, other than for any (a) Tax Benefit Payments due and payable and that remain unpaid as of the Early Termination Notice and (b) Tax Benefit Payment due for the Taxable Year ending with or including the date of the Early Termination Notice (except to the extent that the amount described in clause (b) is included in the Early Termination Payment). If an Exchange occurs after PubCo makes all of the required Early Termination Payments, PubCo shall have no obligations under this Agreement with respect to such Exchange.

(b) In the event that (1) PubCo breaches any of its material obligations under this Agreement, whether as a result of failure to make any payment when due, failure to honor any other material obligation required hereunder or by operation of law as a result of the rejection of this Agreement in a case commenced under the Bankruptcy Code or otherwise or (2)(A) the Corporate Taxpayer shall commence any case, proceeding or other action (i) under any existing or future law of any jurisdiction, domestic or foreign, relating to bankruptcy, insolvency, reorganization or relief of debtors, seeking to have an order for relief entered with respect to it, or seeking to adjudicate a bankruptcy or insolvency, or seeking reorganization, arrangement, adjustment, winding-up, liquidation, dissolution, composition or other relief with respect to it or its debts or (ii) seeking an appointment of a receiver, trustee, custodian, conservator or other similar official for it or for all or any substantial part of its assets, or it shall make a general assignment for the benefit of creditors or (B) there shall be commenced against the Corporate Taxpayer any case, proceeding or other action of the nature referred to in clause (A) above that remains undismissed or undischarged for a period of sixty (60) calendar days, all obligations hereunder shall be automatically accelerated and shall be immediately due and payable, and such obligations shall be calculated as if an Early Termination Notice had been delivered on the date of such breach and shall include, but not be limited to, (x) the Early Termination Payments calculated as if an Early Termination Notice had been delivered on the date of such breach, (y) any Tax Benefit Payment due and payable and that remains unpaid as of the date of such breach, and (z) any Tax Benefit Payment in respect of any TRA Party due for the Taxable Year ending with or including the date of such breach; provided, that procedures similar to the procedures of Section 4.2 shall apply with respect to the determination of the amount payable by PubCo pursuant to this sentence. Notwithstanding the foregoing, in the event that PubCo breaches this Agreement, to the fullest extent permitted by applicable law, each TRA Party shall be entitled to elect to receive the amounts set forth in clauses (x), (y) and (z) above or to seek specific performance of the terms hereof. The parties agree that the failure to make any payment due pursuant to this Agreement within three (3)

21

months of the date such payment is due shall be deemed to be a breach of a material obligation under this Agreement for all purposes of this Agreement, and that it will not be considered to be a breach of a material obligation under this Agreement to make a payment due pursuant to this Agreement within three (3) months of the date such payment is due. Notwithstanding anything in this Agreement to the contrary, it shall not be a breach of a material obligation of this Agreement if the Corporate Taxpayer fails to make any Tax Benefit Payment when due to the extent that the Corporate Taxpayer has insufficient funds to make such payment; provided, that (i) PubCo has used reasonable efforts to obtain such funds and (ii) the interest provisions of Section 5.2 shall apply to such late payment.

(c) Changes of Control.

(i) In the event of a Change of Control, unless the TRA Party Representative elects otherwise, all obligations of PubCo hereunder shall be accelerated and such obligations shall be calculated as if an Early Termination Notice had been delivered on the date of such Change of Control and utilizing the Valuation Assumptions by substituting in each case the terms “the closing date of a Change of Control” in each place where the phrase “Early Termination Date” appears. Such obligations shall include (1) the Early Termination Payments calculated as if the Early Termination Date is the date of such Change of Control, (2) any Tax Benefit Payment due and payable and that remains unpaid as of the date of such Change of Control, and (3) any Tax Benefit Payment in respect of any TRA Party due for any Taxable Year ending prior to, with or including the date of such Change of Control (except to the extent any amounts described in clause (2) or (3) are included in the Early Termination Payment). For the avoidance of doubt, Sections 4.2 and 4.3 shall apply to a Change of Control, mutatis mutandis.

(ii) If the TRA Party Representative elects not to accelerate PubCo’s obligations hereunder, then in the event of a Change of Control, each TRA Party shall continue as a TRA Party under this Agreement after such Change of Control, in which case such TRA Party will not be entitled to receive the amounts set forth in Section 4.1(c)(i) above and Valuation Assumptions (1), (4), (5) and (6) shall apply, substituting the terms “the closing date of a Change of Control” in each place where the phrase “Early Termination Date” appears.

Section 4.2 Early Termination Notice. If PubCo chooses to exercise its right of early termination under Section 4.1(a) above, PubCo shall deliver to the TRA Party Representative notice of such intention to exercise such right (“Early Termination Notice”) and a schedule (the “Early Termination Schedule”) showing in reasonable detail the calculation of the Early Termination Payment(s) due for each relevant TRA Party. Concurrently with the delivery of the Early Termination Notice and the Early Termination Schedule pursuant to the preceding sentence, Pubco shall deliver to each TRA Party a copy of the Early Termination Notice and such portion of the Early Termination Schedule that relates to such TRA Party. The Early Termination Schedule shall become final and binding on all parties thirty (30) calendar days from the first date on which the TRA Party Representative is treated as having received such Schedule or amendment thereto under Section 7.1 unless the TRA Party Representative (i) within thirty (30) calendar days after such date provides PubCo with notice of a material objection to such Schedule made in good faith (“Material Objection Notice”) or (ii) provides a written waiver of such right of a Material Objection Notice within the period described in clause (i) above, in which case such Schedule becomes binding on the date the waiver is received by PubCo. If PubCo and the TRA Party

22

Representative, for any reason, are unable to successfully resolve the issues raised in such notice within thirty (30) calendar days after receipt by PubCo of the Material Objection Notice, PubCo and the TRA Party Representative shall employ the Reconciliation Procedures set forth in Section 7.9 in which case such Schedule becomes binding ten (10) calendar days after the conclusion of the Reconciliation Procedures.

Section 4.3 Payment upon Early Termination.

(a) Within three (3) Business Days after an Early Termination Effective Date, PubCo shall pay to each relevant TRA Party an amount equal to the Early Termination Payment in respect of such TRA Party. Such payment shall be made by wire transfer of immediately available funds to a bank account or accounts designated by such TRA Party or as otherwise agreed by PubCo and such TRA Party or, in the absence of such designation or agreement, by check mailed to the last mailing address provided by such TRA Party to the Corporate Taxpayer.

(b) “Early Termination Payment” in respect of a TRA Party shall equal the present value, discounted at the Early Termination Rate as of the applicable Early Termination Effective Date, of all Tax Benefit Payments in respect of such TRA Party that would be required to be paid by PubCo beginning from the Early Termination Date and assuming that the Valuation Assumptions in respect of such TRA Party are applied and that each Tax Benefit Payment for the relevant Taxable Year would be due and payable on the due date (without extensions) under applicable law as of the Early Termination Effective Date for filing of IRS Form 1120 (or any successor form) of the Corporate Taxpayer.

ARTICLE V

SUBORDINATION AND LATE PAYMENTS

Section 5.1 Subordination. Notwithstanding any other provision of this Agreement to the contrary, any Tax Benefit Payment required to be made by PubCo to the TRA Parties under this Agreement shall rank subordinate and junior in right of payment to any principal, interest or other amounts due and payable in respect of any obligations in respect of indebtedness for borrowed money of PubCo and its Subsidiaries (“Senior Obligations”) and shall rank pari passu in right of payment with all current or future unsecured obligations of PubCo that are not Senior Obligations. To the extent that any payment under this Agreement is not permitted to be made at the time payment is due as a result of this Section 5.1 and the terms of agreements governing Senior Obligations, such payment obligation nevertheless shall accrue for the benefit of TRA Parties and PubCo shall make such payments at the first opportunity that such payments are permitted to be made in accordance with the terms of the Senior Obligations. Notwithstanding any other provision of this Agreement to the contrary, to the extent that PubCo or any of its Affiliates enters into future Tax receivable or other similar agreements (“Future TRAs”), PubCo shall ensure that the terms of any such Future TRA shall provide that the Tax Attributes subject to this Agreement are considered senior in priority to any Tax attributes subject to any such Future TRA for purposes of calculating the amount and timing of payments under any such Future TRA.

23

Section 5.2 Late Payments by PubCo. The amount of all or any portion of any Tax Benefit Payment or Early Termination Payment not made to the TRA Parties when due under the terms of this Agreement, whether as a result of Section 5.1 or otherwise, shall be payable together with any interest thereon, computed at the Default Rate and commencing from the date on which such Tax Benefit Payment or Early Termination Payment was first due and payable to the date of actual payment.

ARTICLE VI

NO DISPUTES; CONSISTENCY; COOPERATION

Section 6.1 Participation in the Corporate Taxpayer’s and OpCo’s Tax Matters. Except as otherwise provided herein, and except as provided in the OpCo Agreement, the Corporate Taxpayer shall have full responsibility for, and sole discretion over, all Tax matters concerning the Corporate Taxpayer and OpCo, including without limitation the preparation, filing or amending of any Tax Return and defending, contesting or settling any issue pertaining to Taxes. Notwithstanding the foregoing, PubCo shall notify the TRA Party Representative of, and keep the TRA Party Representative reasonably informed with respect to, the portion of any audit, examination or any other administrative or judicial proceeding (a “Tax Proceeding”) of the Corporate Taxpayer and OpCo by a Taxing Authority the outcome of which is reasonably expected to materially and adversely affect the rights and obligations of a TRA Party under this Agreement, (ii) shall provide to the TRA Party Representative reasonable opportunity to provide information and other input to the Corporate Taxpayer, OpCo and their respective advisors concerning the conduct of any such portion of such audit, and (iii) shall not enter into any settlement with respect to any such portion of a Tax Proceeding that could have a material and adverse effect on the TRA Parties’ rights (including the right to receive payments) under this Agreement without the written consent of the TRA Party Representative, such consent not to be unreasonably withheld, conditioned, or delayed; provided, however, that the Corporate Taxpayer and OpCo shall not be required to take any action that is inconsistent with any provision of the OpCo Agreement; provided, further, that, notwithstanding anything to the contrary contained herein, the Corporate Taxpayer shall prepare, file, and/or amend all Tax Returns in accordance with applicable law (including with respect to the calculation of taxable income and any calculations required to be made under this Agreement) and nothing in this Agreement shall prevent the TRA Party Representative from disputing such Tax matters in accordance with Section 7.9.

Section 6.2 Consistency. PubCo and the TRA Parties agree to report and cause to be reported for all purposes, including U.S. federal, state and local Tax purposes and financial reporting purposes, all Tax-related items (including, without limitation, the Basis Adjustments and each Tax Benefit Payment) in a manner consistent with that contemplated by this Agreement or specified by PubCo in any Schedule required to be provided by or on behalf of PubCo under this Agreement unless otherwise required by law. PubCo shall (and shall cause OpCo and its other Subsidiaries to) use commercially reasonable efforts (for the avoidance of doubt, taking into account the interests and entitlements of all TRA Parties under this Agreement) to defend the Tax treatment contemplated by this Agreement and any Schedule in any audit, contest or similar proceeding with any Taxing Authority.

24

Section 6.3 Cooperation. Each of the TRA Parties shall (a) furnish to PubCo in a timely manner such information, documents and other materials as PubCo may reasonably request for purposes of making any determination or computation necessary or appropriate under this Agreement, preparing any Tax Return or contesting or defending any audit, examination or controversy with any Taxing Authority, (b) make itself available to PubCo and its representatives to provide explanations of documents and materials and such other information as PubCo or its representatives may reasonably request in connection with any of the matters described in clause (a) above, and (c) reasonably cooperate in connection with any such matter, and PubCo shall reimburse each TRA Party for any reasonable and documented out-of-pocket costs and expenses incurred pursuant to this Section 6.3. Upon the request of a TRA Party, the Corporate Taxpayer shall cooperate in taking any action reasonably requested by such TRA Party in connection with its tax or financial reporting and/or the consummation of any assignment or transfer of any of its rights and/or obligations under this Agreement, including without limitation, providing any information or executing any documentation.

Upon such determination that any term or other provision is invalid, illegal or incapable of being enforced, the parties hereto shall negotiate in good faith to modify this Agreement so as to effect the original intent of the parties as closely as possible in an acceptable manner in order that the transactions contemplated hereby are consummated as originally contemplated to the greatest extent possible.

Section 7.6 Successors; Assignment; Amendments; Waivers.

(a) Each TRA Party may assign all or any portion of its rights under this Agreement to any Person as long as such transferee has executed and delivered, or, in connection with such transfer, executes and delivers, a joinder to this Agreement, substantially in form of Exhibit A hereto, agreeing to become a TRA Party for all purposes of this Agreement, except as otherwise provided in such joinder.

(b) No provision of this Agreement may be amended unless such amendment is approved in writing by each of PubCo and by the TRA Parties who would be entitled to receive at least two-thirds of the total amount of the Early Termination Payments payable to all TRA Parties hereunder if PubCo had exercised its right of early termination on the date of the most recent Exchange prior to such amendment (excluding, for purposes of this sentence, all payments made to any TRA Party pursuant to this Agreement since the date of such most recent Exchange); provided, that no such amendment shall be effective if such amendment will have a disproportionate effect on the payments one or more TRA Parties receive under this Agreement

26

unless such amendment is consented in writing by such TRA Parties disproportionately affected who would be entitled to receive at least two-thirds of the total amount of the Early Termination Payments payable to all TRA Parties disproportionately affected hereunder if PubCo had exercised its right of early termination on the date of the most recent Exchange prior to such amendment (excluding, for purposes of this sentence, all payments made to any TRA Party pursuant to this Agreement since the date of such most recent Exchange). No provision of this Agreement may be waived unless such waiver is in writing and signed by the party against whom the waiver is to be effective.

(c) All of the terms and provisions of this Agreement shall be binding upon, shall inure to the benefit of and shall be enforceable by the parties hereto and their respective successors, assigns, heirs, executors, administrators and legal representatives. PubCo shall require and cause any direct or indirect successor (whether by purchase, merger, consolidation or otherwise) to all or substantially all of the business or assets of PubCo, by written agreement, expressly to assume and agree to perform this Agreement in the same manner and to the same extent that PubCo would be required to perform if no such succession had taken place and this agreement shall be construed in a manner to preserve the rights of the TRA Parties in the event of such a succession.

(d) No failure by any party to insist upon the strict performance of any covenant, duty, agreement, or condition of this Agreement, or to exercise any right or remedy consequent upon a breach thereof, shall constitute a waiver of any such breach or any other covenant, duty, agreement, or condition.

Section 7.7 Titles and Subtitles. The titles of the sections and subsections of this Agreement are for convenience of reference only and are not to be considered in construing this Agreement.

Section 7.8 Consent to Jurisdiction; Waiver of Jury Trial.

(a) Each party hereby irrevocably submits to the jurisdiction of the United States District Court for the State of Delaware and the state courts of the State of Delaware for the purposes of any suit, action or other proceeding arising out of this Agreement or any transaction contemplated hereby. Each party hereto further agrees that service of any process, summons, notice or document by United States certified or registered mail (in each such case, prepaid return receipt requested) to such party’s respective address set forth in PubCo’s books and records or such other address or to the attention of such other person as the recipient party has specified by prior written notice to the sending party shall be effective service of process in any action, suit or proceeding in Delaware with respect to any matters to which it has submitted to jurisdiction as set forth above in the immediately preceding sentence. Each party hereby waives, to the fullest extent permitted by applicable law, any objection which they now or hereafter may have to personal jurisdiction or to the laying of venue of any such ancillary suit, action or proceeding brought in the United States District Court for the State of Delaware and the state courts located in the State of Delaware and the parties agree not to plead or claim the same.

(b) Because disputes arising in connection with complex transactions are most quickly and economically resolved by an experienced and expert person and the parties wish applicable state and federal laws to apply (rather than arbitration rules), the parties desire that their disputes be resolved by a judge applying such applicable laws. Therefore, to achieve the best combination of the benefits of the judicial system and of arbitration, each party to this Agreement (including PubCo) hereby waives all rights to trial by jury in any action or proceeding brought to resolve any dispute between or among any of the parties hereto, whether arising in contract, tort, or otherwise, arising out of, connected with, related or incidental to this agreement, the transactions contemplated hereby and/or the relationships established among the parties hereunder.

Section 7.9 Reconciliation. In the event that PubCo and the TRA Party Representative are unable to resolve a disagreement with respect to the matters governed by Sections 2.4 and 4.2 within the relevant period designated in this Agreement (“Reconciliation Dispute”), the Reconciliation Dispute shall be submitted for determination to a nationally recognized expert (the “Expert”) in the particular area of disagreement mutually acceptable to both parties. The Expert shall be a partner or principal in a nationally recognized accounting or law firm, and unless PubCo and the TRA Party Representative agree otherwise, the Expert shall not, and the firm that employs the Expert shall not, have any material relationship with PubCo or the TRA Party Representative or other actual or potential conflict of interest. If PubCo and the TRA Party Representative are unable to agree on an Expert within fifteen (15) calendar days of receipt by the respondent(s) of written notice of a Reconciliation Dispute, then the Expert shall be appointed by the International Chamber of Commerce Centre for Expertise. The Expert shall resolve any matter relating to the TRA Party’s Attribute Schedule or an amendment thereto or the Early Termination Schedule or an amendment thereto within thirty (30) calendar days and shall resolve any matter relating to a Tax Benefit Schedule or an amendment thereto within fifteen (15) calendar days or as soon thereafter as is reasonably practicable, in each case after the matter has been submitted to the Expert for resolution. Notwithstanding the preceding sentence, if the matter is not resolved before any payment that is the subject of a disagreement would be due (in the absence of such disagreement) or any Tax Return reflecting the subject of a disagreement is due, the undisputed amount shall be paid on the date prescribed by this Agreement and such Tax Return may be filed as prepared by the Corporate Taxpayer, subject to adjustment or amendment upon resolution. The costs and expenses relating to the engagement of such Expert or amending any Tax Return shall be borne by PubCo. Any dispute as to whether a dispute is a Reconciliation Dispute within the meaning of this Section 7.9 shall be decided by the Expert. The Expert shall finally determine any Reconciliation Dispute and the determinations of the Expert pursuant to this Section 7.9 shall be binding on the Corporate Taxpayer and each of the TRA Parties and may be entered and enforced in any court having jurisdiction.

Section 7.10 Withholding. PubCo and its Affiliates and representatives shall be entitled to deduct and withhold from any payment payable pursuant to this Agreement such amounts as PubCo is required to deduct and withhold with respect to the making of such payment under the Code or any provision of state, local or foreign Tax law; provided, that prior to deducting or withholding any such amounts, PubCo shall notify the applicable TRA Party and shall consult in good faith with such TRA Party regarding the basis for such deduction or withholding. To the extent that amounts are so withheld and paid over to the appropriate Taxing Authority by PubCo, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the Person in respect of whom such withholding was made. Each TRA Party shall promptly provide PubCo, OpCo or other applicable withholding agent with any applicable Tax forms and certifications (including IRS Form W-9 or the applicable version of IRS Form W-8) reasonably requested, in connection with determining whether any such deductions and withholdings are required under the Code or any provision of U.S. state, local or foreign Tax law.

Section 7.11 Admission of PubCo into a Consolidated Group; Transfers of Corporate Assets.

(a) If PubCo is or becomes a member of an affiliated or consolidated group of corporations that files a consolidated income Tax Return pursuant to Sections 1501 et seq. of the Code or any corresponding provisions of state or local law, then: (i) the provisions of this Agreement shall be applied with respect to the group as a whole; and (ii) Tax Benefit Payments, Early Termination Payments and other applicable items hereunder shall be computed with reference to the consolidated taxable income of the group as a whole.

(b) If the Corporate Taxpayer (or any member of a group described in Section 7.11(a)) transfers or is deemed to transfer any Unit or any Reference Asset to a transferee that is treated as a corporation for U.S. federal income tax purposes (other than a member of a group described in Section 7.11(a)) in a transaction in which the transferee’s basis in the property acquired is determined in whole or in part by reference to such transferor’s basis in such property, then PubCo shall cause such transferee to assume the obligation to make payments hereunder with respect to the applicable Tax Attributes associated with any Reference Asset or interest therein acquired (directly or indirectly) in such transfer (taking into account any gain recognized in the transaction) in a manner consistent with the terms of this Agreement as the transferee (or one of its Affiliates) actually realizes Tax benefits from the Tax Attributes. If OpCo transfers (or is deemed to transfer for U.S. federal income tax purposes) any Reference Asset to a transferee that is treated as a corporation for U.S. federal income tax purposes (other than a member of a group described in Section 7.11(a)) in a transaction in which the transferee’s basis in the property acquired is determined in whole or in part by reference to such transferor’s basis in such property, then for the purposes of calculating payments under this Agreement, OpCo shall be treated as having disposed of the Reference Asset in a wholly taxable transaction. The consideration deemed to be received by OpCo in a transaction contemplated in the prior sentence shall be equal to the fair market value of the deemed transferred asset, plus, to the extent applicable, the amount of any debt that would increase the transferor’s “amount realized” for U.S. federal income tax purposes in connection with such transfer, in the case of a transfer of an encumbered asset (including an interest in an entity classified for U.S. federal income tax purposes as a partnership which has debt outstanding). If any member of a group described in Section 7.11(a) that owns any Unit deconsolidates from the group (or the Corporate Taxpayer deconsolidates from the group), then PubCo shall cause such member (or the parent of the consolidated group in a case where the Corporate Taxpayer deconsolidates from the group) to assume the obligation to make payments hereunder with respect to the applicable Tax Attributes associated with any Reference Asset it owns (directly or indirectly) in a manner consistent with the terms of this Agreement as the member (or one of its Affiliates) actually realizes Tax benefits. If a transferee or a member of a group described in Section 7.11(a) assumes an obligation to make payments hereunder pursuant to either of the foregoing sentences, then the initial obligor is relieved of the obligation assumed.

29

(c) If the Corporate Taxpayer (or any member of a group described in Section 7.11(a)) transfers (or is deemed to transfer for U.S. federal income tax purposes) any Unit in a transaction that is wholly or partially taxable, then for purposes of calculating payments under this Agreement, OpCo shall be treated as having disposed of the portion of any Reference Asset that is indirectly transferred by the Corporate Taxpayer (i.e., taking into account the number of Units transferred) in a wholly or partially taxable transaction in which all income, gain or loss is allocated to the Corporate Taxpayer. The consideration deemed to be received by OpCo shall be equal to the fair market value of the deemed transferred asset, plus, to the extent applicable, the amount of any debt that would increase the transferor’s “amount realized” for U.S. federal income tax purposes in connection with such transfer, in the case of a transfer of an encumbered asset (including an interest in an entity classified for U.S. federal income tax purposes as a partnership which has debt outstanding).

Section 7.12 Confidentiality.

(a) Subject to the last sentence of Section 6.3, each TRA Party and each of their assignees acknowledge and agree that the information of PubCo is confidential and, except in the course of, and to the extent reasonably required in connection with, performing any duties as necessary for PubCo and its Affiliates, as required by law or legal process (in which case, the TRA Party shall provide prompt written notice of such requirement to PubCo) or to enforce the terms of this Agreement, such person shall keep and retain in the strictest confidence and not disclose to any Person any confidential matters or confidential information, acquired pursuant to this Agreement, of PubCo and its Affiliates and successors, concerning OpCo and its Affiliates and successors or the Members, learned by the TRA Party heretofore or hereafter. This Section 7.12 shall not apply to (i) any information that has been made publicly available by PubCo or any of its Affiliates, becomes public knowledge (except as a result of an act of the TRA Party in violation of this Agreement) or is generally known to the business community, (ii) the disclosure of information to the extent necessary for the TRA Party to prosecute or defend claims arising under or relating to this Agreement, and (iii) the disclosure of information to the extent necessary for the TRA Party to prepare and file its Tax Returns, to respond to any inquiries regarding the same from any Taxing Authority or to prosecute or defend any action, proceeding or audit by any Taxing Authority with respect to such returns. Notwithstanding anything to the contrary herein, each TRA Party and each of its assignees (and each employee, representative or other agent of the TRA Party or its assignees, as applicable) may disclose to any and all Persons, without limitation of any kind, the Tax treatment and Tax structure of PubCo, OpCo and their Affiliates, and any of their transactions, and all materials of any kind (including opinions or other Tax analyses) that are provided to the TRA Party relating to such Tax treatment and Tax structure.

(b) If a TRA Party or an assignee commits a breach, or threatens to commit a breach, of any of the provisions of this Section 7.12, PubCo shall have the right and remedy to have the provisions of this Section 7.12 specifically enforced by injunctive relief or otherwise by any court of competent jurisdiction without the need to post any bond or other security, it being acknowledged and agreed that any such breach or threatened breach shall cause irreparable injury to PubCo or any of its Subsidiaries or the TRA Parties and the accounts and funds managed by PubCo and that money damages alone shall not provide an adequate remedy to such Persons. Such rights and remedies shall be in addition to, and not in lieu of, any other rights and remedies available at law or in equity.

Section 7.13 Change in Law. Notwithstanding anything herein to the contrary, if, in connection with an actual or proposed change in law, a TRA Party reasonably believes that the

30

existence of this Agreement could cause income (other than income arising from receipt of a payment under this Agreement) recognized by the TRA Party upon any Exchange by such TRA Party to be treated as ordinary income rather than capital gain (or otherwise taxed at ordinary income rates) for U.S. federal income tax purposes or would have other material adverse Tax consequences to such TRA Party, then at the written election of such TRA Party in its sole discretion (in an instrument signed by such TRA Party and delivered to PubCo) and to the extent specified by such TRA Party, this Agreement (i) shall cease to have further effect with respect to such TRA Party, (ii) shall not apply to an Exchange by such TRA Party occurring after a date specified by such TRA Party, or (iii) shall otherwise be amended in a manner determined by such TRA Party and PubCo as it relates to such TRA Party, provided, that such amendment shall not result in an increase in payments under this Agreement at any time as compared to the amounts and times of payments that would have been due in the absence of such amendment.

Section 7.14 Independent Nature of Rights and Obligations. The rights and obligations of each TRA Party hereunder are several and not joint with the rights and obligations of any other Person. A TRA Party shall not be responsible in any way for the performance of the obligations of any other Person hereunder, nor shall a TRA Party have the right to enforce the rights or obligations of any other Person hereunder (other than PubCo). The obligations of a TRA Party hereunder are solely for the benefit of, and shall be enforceable solely by, PubCo. Nothing contained herein or in any other agreement or document delivered at any closing, and no action taken by any TRA Party pursuant hereto or thereto, shall be deemed to constitute the TRA Parties acting as a partnership, an association, a joint venture or any other kind of entity, or create a presumption that the TRA Parties are in any way acting in concert or as a group with respect to such rights or obligations or the transactions contemplated hereby, and PubCo acknowledges that the TRA Parties are not acting in concert or as a group and will not assert any such claim with respect to such rights or obligations or the transactions contemplated hereby.]

Section 7.15 TRA Party Representative. The TRA Party Representative may resign upon thirty (30) days’ written notice to PubCo. All reasonable, documented out-of-pocket costs and expenses incurred by the TRA Party Representative in its capacity as such shall be promptly reimbursed by PubCo upon invoice and reasonable support therefor by the TRA Party Representative. To the fullest extent permitted by law, none of the TRA Party Representative, any of its Affiliates, or any of the TRA Party Representative’s or Affiliate’s directors, officers, employees, owners or other agents (each a “Covered Person”) shall be liable, responsible or accountable in damages or otherwise to any TRA Party, OpCo or PubCo for damages arising from any action taken or omitted to be taken by the TRA Party Representative or any other Person with respect to any TRA Party, OpCo or PubCo (or any of their Affiliates), except in the case of any action or omission which constitutes, with respect to such Person, willful misconduct or fraud. Each of the Covered Persons may consult with legal counsel, accountants, and other experts selected by it, and any act or omission suffered or taken by it on behalf of any TRA Party, OpCo or PubCo (or any of their Affiliates) or in furtherance of the interests of any TRA Party, OpCo or PubCo (or any of their Affiliates) in good faith in reliance upon and in accordance with the advice of such counsel, accountants, or other experts shall create a rebuttable presumption of the good faith and due care of such Covered Person with respect to such act or omission; provided, that such counsel, accountants, or other experts were selected with reasonable care. Each of the Covered Persons may rely in good faith upon, and shall have no liability to OpCo, PubCo or the TRA Parties (or any of their Affiliates) for acting or refraining from acting upon, any resolution, certificate, statement, instrument, opinion, report, notice, request, consent, order, bond, debenture, or other paper or document reasonably believed by it to be genuine and to have been signed or presented by the proper party or parties.

31

Section 7.16 Exercising Optionholders. Notwithstanding anything to the contrary herein, any TRA Party that holds Units issued after January 1, 2021 as a result of the exercise of an option to purchase such Units, will have no rights hereunder of any kind in respect of such Units, treating such Units as the last to be Exchanged by such TRA Party.
