(a)           (i)  Subject to Section 2.1(a)(ii) hereof, from and after the first anniversary of the date of the closing of the initial public offering and sale of Class A Common Stock (as contemplated by the Corporation’s Registration Statement on Form S-1 (File No. 333-164217)) (the “IPO”), each Holdings Unitholder shall be entitled at any time and from time to time, upon the terms and subject to the conditions hereof, to surrender Holdings Units (other than Unvested Units) to the Corporation in exchange for the delivery by the Corporation of a number of shares of Class A Common Stock that is equal to the product of the number of Holdings Units surrendered multiplied by the Exchange Rate (such exchange, an “Exchange”); provided that any such Exchange is for a minimum of the lesser of 1,000 Holdings Units or all of the Holdings Units (other than Unvested Units) held by such Holdings Unitholder.

(ii)  Notwithstanding anything to the contrary herein, upon the occurrence of any Change in Control Event, each Holdings Unitholder shall be entitled, upon the terms and subject to the conditions hereof, to elect to Exchange Holdings Units for shares of Class A Common Stock; provided, that any such Exchange pursuant to this sentence shall be effective immediately prior to the consummation of the Change in Control (and, for the avoidance of doubt, shall not be effective if such Change of Control is not consummated); and provided further, that any such election pursuant to this Section 2.1(a)(ii) may be withdrawn by the

3

Holdings Unitholder who submitted such election by providing written notice to the Corporation not less than four business days prior to the consummation of the Change in Control.

(b)           A Holdings Unitholder shall exercise its right to Exchange Holdings Units as set forth in Section 2.1(a) above by delivering to the Corporation a written election of exchange in respect of the Holdings Units to be Exchanged substantially in the form of Exhibit A hereto, duly executed by such holder or such holder’s duly authorized attorney, in each case delivered during normal business hours at the principal executive offices of the Corporation.  Subject to Section 2.1(a)(ii), as promptly as practicable following the delivery of such a written election of exchange, and in any event within three business days, the Corporation shall deliver or cause to be delivered at the offices of the then-acting registrar and transfer agent of the Class A Common Stock or, if there is no then-acting registrar and transfer agent of the Class A Common Stock, at the principal executive offices of the Corporation, the number of shares of Class A Common Stock deliverable upon such Exchange, registered in the name of the relevant Exchanging Holdings Unitholder.  To the extent the Class A Common Stock is settled through the facilities of The Depository Trust Company, the Company will, subject to Section 2.1(c) below, upon the written instruction of an Exchanging Unitholder, use its reasonable best efforts to deliver the shares of Class A Common Stock deliverable to such Exchanging Unitholder, through the facilities of The Depository Trust Company, to the account of the participant of The Depository Trust Company designated by such Exchanging Holder.

(c)           The Corporation and each Exchanging Holdings 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 Corporation 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 in a name other than that of the Holdings Unitholder that requested the Exchange, then such Holdings Unitholder and/or the person in whose name such shares are to be delivered shall pay to the Corporation 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 Corporation that such tax has been paid or is not payable.

(d)           The Corporation covenants and agrees that, prior to taking or causing to be taken any action that would cause interests in Holdings to not meet the requirements of Treasury Regulation section 1.7704-1(h), including, without limitation, issuing any Holdings Units in a transaction required to be registered with the Securities and Exchange Commission pursuant to the Securities Act of 1933, as amended, it will provide at least 15 business days advance written notice describing the proposed action in reasonable detail to the Holdings Unitholders and provide each Holdings Unitholders with the opportunity to effect an Exchange of all such Holdings Unitholder’s Holdings Units in accordance with the terms of this Agreement; provided, however, that in no event will the Corporation take or cause to be taken any action that would cause interests in Holdings to not meet the requirements of Treasury Regulation section 1.7704-1(h) prior to the first anniversary of the closing of the IPO.  Provided that the notice and opportunity to Exchange contemplated by the previous sentence has been provided the Holdings Unitholders, then, notwithstanding anything to the contrary herein, if the Board of Directors of the Corporation, after consultation with its outside legal counsel and tax advisor, shall determine in good faith that interests in Holdings do not meet the requirements of Treasury Regulation

4

section 1.7704-1(h), the Corporation may impose such restrictions on Exchange as the Corporation may reasonably determine to be necessary or advisable so that Holdings is not treated as a “publicly traded partnership” under Section 7704 of the Code.

(e)           For the avoidance of doubt, and notwithstanding anything to the contrary herein, a Holdings Unitholder shall not be entitled to Exchange Holdings Units to the extent the Corporation reasonably determines in good faith that such Exchange (i) would be prohibited by law or regulation or (ii) would not be permitted under any other agreement with the Corporation or its subsidiaries to which such Holdings Unitholder is then subject (including, without limitation, the Holdings LLC Agreement) or any written policies of the Corporation relating to insider trading then applicable to such Holdings Unitholder.  For avoidance of doubt, no Exchange shall be deemed to be prohibited by any law or regulation pertaining to the registration of securities if such securities have been so registered or if any exemption from such registration requirements is reasonably available.

SECTION 2.2.   Adjustment.

(a)           The Exchange Rate shall be adjusted accordingly if there is: (a) any subdivision (by any unit split, unit distribution, reclassification, reorganization, recapitalization or otherwise) or combination (by reverse unit split, reclassification, reorganization, recapitalization or otherwise) of the Holdings Units that is not accompanied by an identical subdivision or combination of the Class A Common Stock; or (b) any subdivision (by any stock split, stock dividend or distribution, reclassification, reorganization, recapitalization or otherwise) or combination (by reverse stock split, reclassification, reorganization, recapitalization or otherwise) of the Class A Common Stock that is not accompanied by an identical subdivision or combination of the Holdings Units. If there is any reclassification, reorganization, recapitalization or other similar transaction in which the Class A Common Stock are converted or changed into another security, securities or other property, then upon any subsequent Exchange, an exchanging Holdings Unitholder shall be entitled to receive the amount of such security, securities or other property that such exchanging Holdings Unitholder would have received if such Exchange had occurred immediately prior to the effective date of such reclassification, reorganization, recapitalization or other similar transaction, 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 reclassification, reorganization, recapitalization or other similar transaction. For the avoidance of doubt, if there is any reclassification, reorganization, recapitalization or other similar transaction in which the Class A Common Stock are converted or changed into 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.  This Agreement shall apply to the Holdings Units held by the Holdings Unitholders and their Permitted Transferees as of the date hereof, as well as any Holdings Units hereafter acquired by a Holdings Unitholder and his or her or its Permitted Transferees. This Agreement shall apply to, mutatis mutandis, and all references to “Holdings Units” shall be deemed to include, any security, securities or other property of Holdings which may be issued in respect of, in exchange for or in substitution of Holdings Units by reason of any distribution or dividend, split, reverse split,

5

combination, reclassification, reorganization, recapitalization, merger, exchange (other than an Exchange) or other transaction.

SECTION 2.3.   Class A Common Stock to be Issued.

(a)           The Corporation covenants and agrees to deliver shares of Class A Common Stock that have been registered under the Securities Act with respect to any Exchange to the extent that a registration statement is effective and available for such shares.  In the event that any Exchange in accordance with this Agreement is to be effected at a time when any required registration has not become effective or otherwise is unavailable, upon the request and with the reasonable cooperation of the Holdings Unitholder requesting such Exchange, the Corporation shall use its reasonable best efforts to promptly facilitate such Exchange pursuant to any reasonably available exemption from such registration requirements.  The Corporation shall use its reasonable best efforts to list the Class A Common Stock required to be delivered upon exchange prior to such delivery upon each national securities exchange or inter-dealer quotation system upon which the outstanding Class A Common Stock may be listed or traded at the time of such delivery. Nothing contained herein shall be construed to preclude the Corporation or Holdings from satisfying their obligations in respect of the exchange of the Holdings Units by delivery of Class A Common Stock which are held in the treasury of the Corporation or Holdings or any of their subsidiaries.

(b)           The Corporation 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 upon any such Exchange; provided that nothing contained herein shall be construed to preclude the Corporation from satisfying its obligations in respect of any such Exchange by delivery of purchased shares of Class A Common Stock (which may or may not be held in the treasury of the Corporation or any subsidiary thereof).

(c)           Prior to the date of this Agreement, the Corporation has taken 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 Corporation (including derivative securities with respect thereto) and any securities which may be deemed to be equity securities or derivative securities of the Corporation for such purposes that result from the transactions contemplated by this Agreement, by each director or officer of the Corporation who may reasonably be expected to be subject to the reporting requirements of Section 16(a) of the Exchange Act with respect to the Corporation upon the registration of any class of equity security of the Corporation pursuant to Section 12 of the Exchange Act (with the authorizing resolutions specifying the name of each such officer or director whose acquisition or disposition of securities is to be exempted and the number of securities that may be acquired and disposed of by each such person pursuant to this Agreement).

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

6

(e)           The Corporation covenants that all 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 Corporation or to any right of first refusal or other right in favor of any person or entity.

SECTION 4.7.   Waiver. 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 waiver of any such breach of any other covenant, duty, agreement or condition.

SECTION 4.8.   Submission to Jurisdiction; Waiver of Jury Trial.

(a)           Any and all disputes which cannot be settled amicably, including any ancillary claims of any party, arising out of, relating to or in connection with the validity, negotiation, execution, interpretation, performance or non-performance of this Agreement (including the validity, scope and enforceability of this arbitration provision) shall be finally settled by arbitration conducted by a single arbitrator in New York in accordance with the then-existing Rules of Arbitration of the International Chamber of Commerce. If the parties to

9

the dispute fail to agree on the selection of an arbitrator within thirty (30) days of the receipt of the request for arbitration, the International Chamber of Commerce shall make the appointment.  The arbitrator shall be a lawyer and shall conduct the proceedings in the English language.  Performance under this Agreement shall continue if reasonably possible during any arbitration proceedings.

Such ancillary judicial proceedings include any suit, action or proceeding to compel arbitration, to obtain temporary or preliminary judicial relief in aid of arbitration, or to confirm an arbitration award. The parties acknowledge that the fora designated by this paragraph (c) have a reasonable relation to this Agreement, and to the parties’ relationship with one another.

(ii)           The parties hereby waive, 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 any court referred to in the preceding paragraph of this Section 4.8 and such parties agree not to plead or claim the same.

(d)           Notwithstanding any provision of this Agreement to the contrary, this Section 3.8 shall be construed to the maximum extent possible to comply with the laws of the State of Delaware, including the Delaware Uniform Arbitration Act (10 Del. C. § 5701 et  seq.) (the “Delaware Arbitration Act”).  If, nevertheless, it shall be determined by a court of competent jurisdiction that any provision or wording of this Section 4.8, including any rules of the International Chamber of Commerce, shall be invalid or unenforceable under the Delaware Arbitration Act, or other applicable law, such invalidity shall not invalidate all of this Section 4.8.  In that case, this Section 4.8 shall be construed so as to limit any term or provision so as to make it valid or enforceable within the requirements of the Delaware Arbitration Act or other applicable law, and, in the event such term or provision cannot be so limited, this Section 3.8 shall be construed to omit such invalid or unenforceable provision.

SECTION 4.9.   Counterparts. This Agreement may be executed and delivered (including by facsimile transmission or by e-mail delivery of a “.pdf” format data file) in one or more counterparts, and by the different parties hereto in separate counterparts, each of which

10

when executed and delivered shall be deemed to be an original but all of which taken together shall constitute one and the same agreement. Copies of executed counterparts transmitted by telecopy, by e-mail delivery of a “.pdf” format data file or other electronic transmission service shall be considered original executed counterparts for purposes of this Section 4.9.

SECTION 4.10.   Tax Treatment. This Agreement shall be treated as part of the partnership agreement of Holdings 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. As required by the Code and the Treasury Regulations promulgated thereunder: (a) the parties shall report an Exchange consummated hereunder as a taxable sale of Holdings Units by a Holdings Unitholder to the Corporation; and (b) no party shall take a contrary position on any income tax return, amendment thereof or communication with a taxing authority.

SECTION 4.11.   Specific Performance.  The parties hereto agree that irreparable damage would occur in the event that any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached.  It is accordingly agreed that the parties shall be entitled to specific performance of the terms and provisions hereof, in addition to any other remedy to which they are entitled at law or in equity.

SECTION 4.12.   Independent Nature of Holdings Unitholders’ Rights and Obligations.  The obligations of each Holdings Unitholder hereunder are several and not joint with the obligations of any other Holdings Unitholder, and no Holdings Unitholder shall be responsible in any way for the performance of the obligations of any other Holdings Unitholder under hereunder.  The decision of each Holdings Unitholder to enter into to this Agreement has been made by such Holdings Unitholder independently of any other Holdings Unitholder. Nothing contained herein, and no action taken by any Holdings Unitholder pursuant hereto, shall be deemed to constitute the Holdings Unitholders as a partnership, an association, a joint venture or any other kind of entity, or create a presumption that the Holdings Unitholders are in any way acting in concert or as a group with respect to such obligations or the transactions contemplated hereby and the Corporation acknowledges that the Holdings Unitholders are not acting in concert or as a group, and the Corporation will not assert any such claim, with respect to such obligations or the transactions contemplated hereby.

SECTION 4.13.   Applicable Law. This Agreement shall be governed by, and construed in accordance with, the law of the State of Delaware.
