EXCHANGES

Section 2.1 Exchange of Exchangeable Units for Class A Common Stock.

(a) The Exchanges.

(i) Elective Exchanges.

(A) Subject to Section 2.1(c), and otherwise upon the terms and subject to the conditions hereof and of the Partnership Agreement, each Partnership Unitholder shall have the right from time to time (but subject to the Class C Holder Restriction) to surrender Exchangeable Units in at least the Minimum Exchangeable Amount (in each case, free and clear of all liens, encumbrances, rights of first refusal and similar restrictions, except for those arising under this Agreement, the Policies and the Partnership Agreement) to the Partnership and to thereby cause the Partnership to deliver to that Partnership Unitholder (or its designee) the Exchange Consideration as set forth herein (an “Elective Exchange”).

(B) A Partnership Unitholder shall exercise its right to an Elective Exchange by delivering to the Partnership, with a contemporaneous copy delivered to the Company, in each case during normal business hours at the principal executive offices of the Partnership and the Company, respectively, a written election of exchange in respect of the Exchangeable Units to be exchanged substantially in the form of Exhibit A hereto (an “Elective Exchange Notice”), duly executed by such Partnership Unitholder.

(C) A Partnership Unitholder may specify, in an applicable Elective Exchange Notice, that the Elective Exchange is to be contingent (including as to timing) upon the occurrence of any transaction or event, including the consummation of a purchase by another Person (whether in a tender or exchange offer, an underwritten offering, block trade, change of control transaction or otherwise) of shares of Class A Common Stock or any merger, consolidation or other business combination. The termination of a transaction or event specified in the preceding sentence, prior to the consummation thereof, shall terminate all of the exchanging Partnership Unitholder’s, Partnership’s and Company’s rights and obligations under this Section 2.1(a)(i) arising from that particular Elective Exchange Notice, and all actions taken to effect the Elective Exchange contemplated by that Elective Exchange Notice shall be deemed rescinded.

4

(D) After the Elective Exchange Notice has been delivered to the Partnership, and unless such Partnership Unitholder timely has delivered a Retraction Notice pursuant to Section 1.1(a)(i)(E) or the Partnership has refused to honor the request in full pursuant to Section 2.1(b)(i), the Partnership will effect the Elective Exchange in accordance with the Policies and inform the Partnership Unitholder of the effective date of such Elective Exchange (the “Elective Exchange Date”).

(E) Notwithstanding anything herein to the contrary, if a Retraction Event occurs after the delivery of an Elective Exchange Notice and prior to 5:00 p.m., New York City time, on the Business Day immediately prior to the applicable Elective Exchange Date (the “Retraction Deadline”), a Partnership Unitholder may withdraw or amend its Elective Exchange Notice, in whole or in part, by giving written notice at any time prior to the Retraction Deadline (a “Retraction Notice”) to the Partnership (with a copy to the Company) specifying (A) the number of withdrawn Exchangeable Units and (B) the number of Exchangeable Units as to which the Elective Exchange Notice remains in effect. The timely delivery of a Retraction Notice indicating an entire withdrawal of the Elective Exchange Notice shall terminate all of the exchanging Partnership Unitholder’s, Partnership’s and Company’s rights and obligations under this Section 2.1(a)(i) arising from that particular Elective Exchange Notice, and all actions taken to effect the Elective Exchange contemplated by that Elective Exchange Notice shall be deemed rescinded.

(ii) Mandatory Exchanges.

(A) Upon the occurrence of any of the circumstances set out in Section 7.8.2 of the Partnership Agreement and in accordance with the terms and conditions thereof, the General Partner or the Class B Committee, as applicable, may exercise its right to cause a mandatory exchange of a Partnership Unitholder’s Exchangeable Units (a “Mandatory Exchange”) by delivering to the Partnership Unitholder a written notice pursuant to the notice provisions of the Partnership Agreement (an “Mandatory Exchange Notice”) specifying the basis for the Mandatory Exchange, the Exchangeable Units of the Partnership to which the Mandatory Exchange applies and the effective date of such Mandatory Exchange (the “Mandatory Exchange Date”), which shall be no earlier than ten (10) Business Days after delivery of the Mandatory Exchange Notice. Upon the Mandatory Exchange Date, unless the Partnership has determined such Mandatory Exchange would be in breach of Section 2.1(b)(i), the Partnership will effect the Mandatory Exchange in accordance with the Policies.

(b) Additional Terms Applying to Exchanges.

(i) For the avoidance of doubt, and notwithstanding anything else in this Agreement or the Partnership Agreement to the contrary: (A) the Company may elect to settle an Exchange, in whole or in part, by delivery of the Cash Settlement as to all or any portion of the total number of Exchangeable Units being surrendered and delivery of Class A Common Stock as to any remaining portion not satisfied by the Cash Settlement; and (B) the Board of Directors (or a committee to which the Board of Directors has delegated such authority) may, in its reasonable discretion, deny or limit, in whole or in part, any Exchange that fails to comply with any requirements therefor that the Company, the Partnership, or the Board of Directors may have established, or that, if effected, would adversely affect the trading markets in the Company’s Common Stock as determined by the Board of Directors (or a committee thereof to which the Board of Directors has delegated such authority) in its reasonable discretion. In particular, a Partnership Unitholder shall not be entitled to an Exchange, and the Company and Partnership shall have the right to refuse to honor any request for an Exchange, at any time or during any period if the Company or the Partnership determines, after consultation with counsel, that such Exchange (x) would be prohibited by law or regulation (including, without limitation, the unavailability of a registration of such Exchange under the Securities Act or an exemption from the registration requirements thereof) or (y) would not be permitted under any agreement with the Company, the Partnership or any of their subsidiaries to which the applicable Partnership Unitholder is party (including, without limitation, the Partnership Agreement) or (solely in the case of an Exchange requested by an officer, director or other personnel of the Company, the Partnership or any of their subsidiaries) any written policies of the Company related to restrictions on trading applicable to its officers, directors or other personnel.

(ii) On an Exchange Date, all rights of the exchanging Partnership Unitholder as a holder of the Exchangeable Units shall cease, and unless the Company has elected Cash Settlement as to all Exchangeable Units tendered, such Partnership Unitholder (or its designee) shall be treated for all purposes as having become the record holder of the shares of Class A Common Stock to be received by the exchanging Partnership Unitholder in respect of such Exchange.

5

(iii) At least two Business Days before the Exchange Date, the Company shall give written notice (the “Contribution Notice”) to the Partnership (with a copy to the exchanging Partnership Unitholders) of its intended settlement method; provided that if the Company does not timely deliver a Contribution Notice, the Company shall be deemed not to have elected the Cash Settlement method.

(c) Exchange Consideration. On or promptly after an Exchange Date, provided the Partnership Unitholder has satisfied its obligations under Section 2.1(b)(i), the Company shall cause the Transfer Agent to register electronically in the name of such Partnership Unitholder (or its designee) in book-entry form the shares of Class A Common Stock issuable upon the applicable Exchange, or, if the Company has so elected, shall deliver or cause to be delivered to such Partnership Unitholder (or its designee), the Cash Settlement. Notwithstanding the foregoing, the Company shall have the right but not the obligation (in lieu of the Partnership) to have the Company acquire Exchangeable Units directly from an exchanging Partnership Unitholder in exchange for shares of Class A Common Stock or, at the option of the Company, the Cash Settlement. If an exchanging Partnership Unitholder receives the shares of Class A Common Stock or the Cash Settlement that such Partnership Unitholder is entitled to receive from the Company pursuant to this Section 2.1(c), the Partnership Unitholder shall have no further right to receive shares of Class A Common Stock from the Partnership or the Company in connection with that Exchange. Notwithstanding anything set forth in this Section 2.1(c) to the contrary, to the extent the Class A Common Stock is settled through the facilities of The Depository Trust Company, the Partnership or the Company will, pursuant to the Exchange Notice submitted by the Partnership Unitholder, deliver the shares of Class A Common Stock deliverable to such exchanging Partnership Unitholder through the facilities of The Depository Trust Company to the account of the participant of The Depository Trust Company designated by such exchanging Partnership Unitholder in the Exchange Notice. Upon any Exchange, the Partnership or the Company, as applicable, shall take such actions as (A) may be required to ensure that such Partnership Unitholder receives the shares of Class A Common Stock or the Cash Settlement that such exchanging Partnership Unitholder is entitled to receive in connection with such Exchange pursuant to this Section 2.1 and (B) may be reasonably within its control that would cause such Exchange to be treated for purposes of the Tax Receivable Agreement as an “Exchange” (as such term is defined in the Tax Receivable Agreement). Notwithstanding any other provisions of this Agreement to the contrary, in the event that the Company elects a Cash Settlement, the Company shall only be obligated to contribute to the Partnership (or, if the Company elects to settle directly pursuant to Section 2.1(a)(ii), settle directly for an amount equal to), an amount in respect of such Cash Settlement equal to the net proceeds (after deduction of any underwriters’ discounts and commissions) from the sale by the Company of a number of shares of Class A Common Stock equal to the number of Exchangeable Units being Exchanged for such Cash Settlement. Except as otherwise required by applicable law, the Company shall, for U.S. federal income tax purposes, be treated as paying an appropriate portion of the selling expenses described in the previous sentence as agent for and on behalf of the exchanging Partnership Unitholder.

(d) Joinder to Stockholders’ Agreement. For clarity, any Exchange of Class C Units for shares of Class A Common Stock shall be accompanied by and conditioned on delivery by such exchanging Partnership Unitholder of a joinder to the Stockholders’ Agreement, in form and substance acceptable to the Company.

(e) Expenses. Subject to any other arrangement or agreement among the Partnership and an applicable Partnership Unitholder, the Company, the Partnership, and each exchanging Partnership Unitholder shall bear their own expenses in connection with the consummation of any Exchange, whether or not any such Exchange is ultimately consummated, except that the Company shall bear any transfer taxes, stamp taxes or duties, or other similar taxes in connection with, or arising by reason of, any Exchange; provided, however, that if any shares of Class A Common Stock are to be delivered pursuant to an Elective Exchange in a name other than that of the Partnership Unitholder that requested the Exchange (or The Depository Trust Company or its nominee for the account of a participant of The Depository Trust Company that will hold the shares for the account of such Partnership Unitholder) or the Cash Settlement is to be paid to a Person other than the Partnership Unitholder that requested the Exchange, then such Partnership Unitholder or the Person in whose name such shares are to be delivered or to whom the Cash Settlement is to be paid shall pay to the Company the amount of any transfer taxes, stamp taxes or duties, or other similar taxes in connection with, or arising by reason of, such Exchange or shall establish to the reasonable satisfaction of the Company that such tax has been paid or is not payable.

(f) Publicly Traded Partnership. Notwithstanding anything to the contrary herein, if the General Partner of the Partnership determines that an Exchange would pose a material risk that the Partnership would become a “publicly traded partnership” under Section 7704 of the Code, the Exchange shall be null and void.

6

Section 2.2 Adjustment. To the extent not reflected in an adjustment to the Exchange Rate, if there is any stock split, reverse split, stock dividend, stock combination, reclassification, recapitalization, reorganization, merger, consolidation, other business combination or other similar event or transaction relating to, affecting or in respect of the Class A Common Stock (an “Adjustment Transaction”), including any Adjustment Transaction in which the Class A Common Stock is converted or changed or exchanged into or for another security, securities or other property, then upon any subsequent Exchange, an exchanging Partnership Unitholder shall be entitled to receive the amount of such security, securities or other property that such exchanging Partnership Unitholder would have received if such Exchange had occurred immediately prior to the effective date of such Adjustment Transaction, including taking into account any adjustment as a result of any subdivision (by any split, distribution or dividend, reclassification, reorganization, recapitalization or otherwise) or combination (by reverse split, reclassification, recapitalization or otherwise) of such security, securities or other property that occurs after the effective time of such Adjustment Transaction. For the avoidance of doubt, if there is any Adjustment Transaction in which the Class A Common Stock is converted or changed or exchanged into or for another security, securities or other property, this Section 2.2 shall continue to be applicable, mutatis mutandis, with respect to such security or other property.

Section 2.3 Class A Common Stock to be Issued.

(a) Class A Common Stock Reserve. The Company shall at all times reserve and keep available out of its authorized but unissued Class A Common Stock, solely for the purpose of issuance upon an Exchange, such number of shares of Class A Common Stock as shall be deliverable under this Agreement upon all such Exchanges; provided, however, that nothing contained herein shall be construed to preclude the Company from satisfying its obligations in respect of any such Exchange by delivery of unencumbered purchased shares of Class A Common Stock (which may or may not be held in the treasury of the Company or any subsidiary thereof).

(b) Rule 16(b) Exemption. The Company has taken and will take all such steps as may be required to cause to qualify for exemption under Rule 16b-3(d) or (e), as applicable, under the Exchange Act, and be exempt for purposes of Section 16(b) under the Exchange Act, any acquisitions or dispositions of equity securities of the Company (including derivative securities with respect thereto) and any securities that may be deemed to be equity securities or derivative securities of the Company for such purposes that result from the transactions contemplated by this Agreement, by each director or officer of the Company (including directors-by-deputization) who may reasonably be expected to be subject to the reporting requirements of Section 16(a) of the Exchange Act with respect to the Company upon the registration of any class of equity security of the Company pursuant to Section 12 of the Exchange Act.

(c) Takeover Law. If any Takeover Law or other similar law or regulation becomes or is deemed to become applicable to this Agreement or any of the transactions contemplated hereby, the Company shall use its reasonable best efforts to render such law or regulation inapplicable to all of the foregoing.

(d) Validity of Class A Common Stock. The Company covenants that all shares of Class A Common Stock issued upon an Exchange will, upon issuance, be validly issued, fully paid and non-assessable and not subject to any preemptive right of stockholders of the Company or to any right of first refusal or other right in favor of any Person.

Section 2.4 Withholding.

(a) Withholding of Class A Common Stock Permitted. If the Company or the Partnership shall be required to withhold any amounts by reason of any federal, state, local or foreign tax laws or regulations in respect of any Exchange, the Company or the Partnership, as the case may be, shall be entitled to take such action as it deems appropriate in order to ensure compliance with such withholding requirements, including, at its option, withholding shares of Class A Common Stock with a fair market value equal to the amount of any taxes that the Company or the Partnership, as the case may be, may be required to withhold with respect to such Exchange. To the extent that amounts are (or property is) so withheld and paid over to the appropriate taxing authority, such withheld amounts (or property) shall be treated for all purposes of this Agreement as having been paid (or delivered) to the applicable Partnership Unitholder.

7

(b) Notice of Withholding. If the Company or the Partnership determines that any amounts by reason of any federal, state, local or foreign tax laws or regulations are required to be withheld in respect of any Exchange, the Company or the Partnership, as the case may be, shall use commercially reasonable efforts to promptly notify the exchanging Partnership Unitholder and shall consider in good faith any theories, positions or alternative arrangements that such Partnership Unitholder raises (reasonably in advance of the date on which the Company or the Partnership believes withholding is required) as to why withholding is not required or that may avoid the need for such withholding, provided that none of the Company or the Partnership is required to incur additional costs as a result of such obligation and this Section 2.4(b) shall not in any manner limit the authority of the Company or the Partnership to withhold taxes with respect to an exchanging Partnership Unitholder pursuant to Section 2.4(a).

Section 2.5 Tax Treatment. Unless otherwise required by applicable law, the parties hereto acknowledge and agree that an Exchange with the Partnership or the Company shall be treated as a direct exchange between the Company and the Partnership Unitholder for U.S. federal and applicable state and local income tax purposes. The parties hereto intend to treat any Exchange consummated hereunder as a taxable exchange for U.S. federal and applicable state and local income tax purposes except as otherwise agreed to in writing by the exchanging Partnership Unitholder and the Company or required by applicable law. This Agreement shall be treated as part of the partnership agreement of the Partnership as described in Section 761(c) of the Code and Sections 1.704-1(b)(2)(ii)(h) and 1.761-1(c) of the Treasury Regulations promulgated thereunder.

Section 2.6 Contribution of the Company. In connection with any Exchange between a Partnership Unitholder and the Partnership, the Company shall contribute to the Partnership the shares of Class A Common Stock or Cash Settlement that the Partnership Unitholder is entitled to receive in such Exchange. Unless the Partnership Unitholder has timely delivered a Retraction Notice as provided in Section 1.1(a)(i)(E), on the Exchange Date (to be effective immediately prior to the close of business on the Exchange Date) (i) the Company shall make a capital contribution to the Partnership (in the form of the shares of Class A Common Stock or the Cash Settlement that the Partnership Unitholder is entitled to receive in such Exchange) required under this Section 2.6 and (ii) the Partnership shall issue to the Company a number of Class A Units equal to the number of Exchangeable Units surrendered by the Partnership Unitholder. The timely delivery of a Retraction Notice shall terminate all of the Partnership’s and the Company’s rights and obligations under this Section 2.6 arising from the Exchange Notice.

Section 2.7 Apportionment of Distributions. Distributions with a Distribution Record Date (as defined in Section 4.7.1 of the Partnership Agreement) on or before the Exchange Date shall be made to the Exchanging Partnership Unitholder.

Section 2.8 Nature of Determinations. All determinations, interpretations, calculations, adjustments and other actions of the Partnership, the Company, the Board of Directors (or a committee to which the Board of Directors has delegated such authority), the General Partner or a designee of any of the foregoing that are within such Person’s authority hereunder shall be reasonable and made in good faith.

ARTICLE IV

MISCELLANEOUS

Section 4.1 Additional Partnership Unitholders. If a Partnership Unitholder validly transfers any or all of such holder’s Class C Units to another Person in a transaction in accordance with, and not in contravention of, the Partnership Agreement, then such transferee (each, a “Permitted Transferee”) shall, as a condition to such transfer, be required to execute and deliver a joinder to this Agreement, substantially in the form of Exhibit B hereto, whereupon

9

such Permitted Transferee shall become a Partnership Unitholder hereunder. To the extent the Partnership issues Exchangeable Units in the future to a Person who is not a Partnership Unitholder, then the Partnership shall, as a condition to such issuance, require each holder of such Exchangeable Units to execute and deliver a joinder to this Agreement, substantially in the form of Exhibit B hereto, whereupon such holder shall become a Partnership Unitholder hereunder. Other than to a Permitted Transferee, a Partnership Unitholder may not assign or transfer any of its rights or obligations under this Agreement. No Person shall have any rights hereunder until he, she, or it has executed this Agreement (including by executing a joinder thereto).

Section 4.2 Term; Termination. This Agreement shall remain in effect (i) as to the Partnership and the Company, until the date on which no Class C Units remain outstanding and there exist no rights to acquire Exchangeable Units, and (ii) as to any Partnership Unitholder, until the date such Partnership Unitholder no longer holds or has any right to acquire Exchangeable Units.

Section 4.3 Notifications. Any notice, demand, consent, election, approval, request, or other communication (collectively, a “notice”) required or permitted under this Agreement must be in writing or electronic form and either delivered personally, sent by certified or registered mail, postage prepaid, return receipt requested or sent by recognized overnight delivery service, electronically or by facsimile transmittal.

Section 4.5 Applicable Law; Venue; Waiver of Jury Trial.

(a) Applicable Law. The parties hereto hereby agree that all questions concerning the construction, validity and interpretation of this Agreement and the performance of the obligations imposed by this Agreement shall be governed by, and construed in accordance with, the internal laws of the State of Delaware without giving effect to any choice of law or conflict of law provision or rule, notwithstanding that public policy in Delaware or any other forum jurisdiction might indicate that the laws of that or any other jurisdiction should otherwise apply based on contacts with such state or otherwise.

(b) Venue. Each of the parties hereto submits to the exclusive jurisdiction of the Court of Chancery in the State of Delaware (or, if (but only if) such court lacks jurisdiction, any state or federal court of the State of Delaware) in any action or proceeding arising out of or relating to this Agreement and agrees that all claims in respect of the action or proceeding may be heard and determined solely and exclusively in such court and the appellate courts therefrom. Each party hereto also agrees not to bring any action or proceeding arising out of or relating to this Agreement in any court other than as aforesaid. Each of the parties hereto waives any defense of inconvenient forum to the maintenance of any action or proceeding so brought and waives any bond, surety, or other security that might be required of any other party hereto with respect thereto. The parties hereto each agree that final judgment in any such suit, action or proceeding brought in such a court shall be conclusive and binding on it and may be enforced in any court to the jurisdiction of which it is subject by a suit upon such judgment.

(c) Waiver of Jury Trial. EACH PARTY HERETO ACKNOWLEDGES AND AGREES THAT ANY CONTROVERSY THAT MAY ARISE UNDER THIS AGREEMENT IS LIKELY TO INVOLVE COMPLICATED AND DIFFICULT ISSUES, AND THEREFORE EACH SUCH PARTY HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES ANY RIGHT SUCH PARTY MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS AGREEMENT, OR THE BREACH, TERMINATION OR VALIDITY OF THIS AGREEMENT, OR THE TRANSACTIONS CONTEMPLATED BY THIS AGREEMENT. EACH PARTY HERETO CERTIFIES AND ACKNOWLEDGES THAT (A) NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER, (B) EACH SUCH PARTY UNDERSTANDS AND HAS CONSIDERED THE IMPLICATIONS OF THIS WAIVER, (C) EACH SUCH PARTY MAKES THIS WAIVER VOLUNTARILY, AND (D) EACH SUCH PARTY HAS BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS Section 4.5.

Section 4.6 References to this Agreement; Headings. Unless otherwise indicated, “Sections,” “clauses” and “Exhibits” mean and refer to designated Sections, clauses, and Exhibits of this Agreement. Words such as “herein,” “hereby,” “hereinafter,” “hereof,” “hereto,” and “hereunder” refer to this Agreement as a whole, unless the context indicates otherwise. All headings in this Agreement are for convenience of reference only and are not intended to define or limit the scope or intent of this Agreement. All exhibits and schedules referred to herein, and as the same may be amended from time to time, are by this reference made a part hereof as though fully set forth herein.

Section 4.7 Binding Provisions. This Agreement is binding upon, and inures to the benefit of, the parties hereto and their respective personal and legal representatives, heirs, executors, successors and Permitted Transferees.

Section 4.8 Construction. Common nouns and pronouns and any variations thereof shall be deemed to refer to masculine, feminine, or neuter, singular or plural, as the identity of the Person, Persons or other reference in the context requires. Every covenant, term and provision of this Agreement shall be construed simply according to its fair meaning and not strictly for or against any party hereto. Any reference to any statute, law, or regulation, form or schedule shall include any amendments, modifications, or replacements thereof. Any reference to any agreement, contract or schedule, unless otherwise stated, shall include any amendments, modifications, or replacements thereof. Whenever used herein, (i) “or” shall include both the conjunctive and disjunctive unless the context requires otherwise, (ii) “any” shall mean “one or more,” and (iii) “including”, “include” and “includes” shall be deemed followed by the words “without limitation.”

11

Section 4.9 Severability. It is expressly understood and agreed that if any provision of this Agreement or the application of any such provision to any party or circumstance shall be determined by any court of competent jurisdiction to be invalid or unenforceable to any extent, the remainder of this Agreement, or the application of such provision to any party or circumstance other than those to which it is so determined to be invalid or unenforceable, shall not be affected thereby, and each provision hereof shall be enforced to the fullest extent permitted by law so long as the economic or legal substance of the matters contemplated by this Agreement is not affected in any manner materially adverse to any party. If the final judgment of a court of competent jurisdiction declares or finds that any term or provision hereof is invalid or unenforceable, the parties hereto agree that the court making the determination of invalidity or unenforceability shall have the power to reduce the scope, duration or portion of the term or provision, or to delete specific words or phrases, and to replace any invalid or unenforceable term or provision with a term or provision that is valid and enforceable and that comes closest to expressing the intention of the invalid or unenforceable term or provision, and this Agreement shall be enforceable as so modified. If such court of competent jurisdiction does not so replace an invalid or unenforceable term or provision, the parties hereto will 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 to the end that the matters contemplated hereby are fulfilled to the fullest extent possible.

Section 4.10 Counterparts. This Agreement and any amendments may be executed simultaneously in two or more counterparts and delivered via facsimile or .pdf, each of which shall be deemed an original and all of which, when taken together, shall constitute one and the same document. The signature of any party to any counterpart shall be deemed a signature to, and may be appended to, any other counterpart.

Section 4.11 No Third-Party Beneficiaries. Each Partnership Unitholder on the date hereof is expected to become a party to this Agreement. Each of their Permitted Transferees and each Person who is or becomes a Partnership Unitholder may become a party hereto, subject to their execution and delivery to the Partnership and the Company of an executed joinder to this Agreement in form and substance acceptable to the Partnership and the Company. This Agreement is not otherwise intended to, and does not, provide or create any rights or benefits in any Person.

Section 4.12 Mutual Drafting. The parties hereto are sophisticated and have been advised by attorneys throughout the transactions contemplated hereby who have carefully negotiated the provisions hereof. As a consequence, the parties do not intend that the presumptions of laws or rules relating to the interpretation of contracts against the drafter of any particular clause should be applied to this Agreement or any agreement or instrument executed in connection herewith, and therefore waive their effects.

Section 4.13 Rights and Remedies Cumulative. The rights and remedies provided by this Agreement are cumulative and the use of any one right or remedy by any party shall not preclude or waive the right to use any or all other remedies. Such rights and remedies are given in addition to any other rights the parties may have by law, statute, ordinance or otherwise. 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 4.14 Amendment. The provisions of this Agreement may be amended only by an instrument in writing approved by the affirmative vote or written or electronic consent of each of (i) the Company, (ii) the Partnership, and (iii) Partnership Unitholders holding a majority of the then outstanding Class C Units; provided that no amendment may disproportionately and adversely affect the rights of a Partnership Unitholder in respect of the Class C Units compared to the rights of other Partnership Unitholders in respect of the Class C Units without the consent of such affected Partnership Unitholder

Section 4.15 Specific Performance. The parties recognize that irreparable injury will result from a breach of any provision of this Agreement and that money damages would be inadequate to fully remedy the injury. Accordingly, in the event of a breach or threatened breach of one or more of the provisions of this Agreement, any party that may be injured (in addition to any other remedies that may be available to that party) shall be entitled (without the need to post any bond, surety, or other security) to one or more preliminary or permanent orders (a) restraining and enjoining any act that would constitute a breach or (b) compelling the performance of any obligation that, if not performed, would constitute a breach.

12

Section 4.16 Independent Nature of Partnership Unitholders’ Rights and Obligations. The obligations of each Partnership Unitholder hereunder are several and not joint with the obligations of any other Partnership Unitholder, and no Partnership Unitholder shall be responsible in any way for the performance of, or failure to perform, the obligations of any other Partnership Unitholder hereunder. The decision of each Partnership Unitholder to enter into this Agreement has been made by such Partnership Unitholder independently of any other Partnership Unitholder. Nothing contained herein, and no action taken by any Partnership Unitholder pursuant hereto, shall be deemed to constitute the Partnership Unitholders as a partnership, an association, a joint venture or any other kind of entity, or create a presumption that the Partnership Unitholders are in any way acting in concert or as a group with respect to such obligations or the transactions contemplated hereby and the Company acknowledges that the Partnership Unitholders are not acting in concert or as a group, and the Company will not assert any such claim, with respect to such obligations or the transactions contemplated hereby.
