5.1Exchange Agent. At or immediately prior to the Effective Time, pursuant to Section 2.2, Parent shall deposit or cause to be deposited with a nationally recognized financial institution or trust company selected by Parent with the Partnership’s prior approval (which approval shall not be unreasonably withheld, conditioned or delayed) to serve as the exchange agent (the “Exchange Agent”), for the benefit of the holders of Eligible Units upon Closing, (a) an aggregate number of shares of Parent Common Stock to be issued innon-certificated book-entry form comprising the amounts required to be delivered in respect of Eligible Units pursuant to Section 4.1 and (b) an aggregate amount of cash comprising approximately the amounts required to be delivered in respect of Eligible Units pursuant to Section 5.5.

Such shares of Parent Common Stock, cash in lieu of fractional shares payable pursuant to Section 5.5 and the amount of any dividends or other distributions deposited with the Exchange Agent pursuant to this Section 5.1 are referred to collectively in this Agreement as the “Exchange Fund”. The Exchange Fund shall not be used for any purpose other than the purpose expressly provided for in this Agreement. The cash portion of the Exchange Fund may be deposited by the Exchange Agent as reasonably directed by Parent. Any interest or other income resulting from such investment shall become a part of the Exchange Fund, and any amounts in excess of the amounts payable pursuant to this Agreement shall be promptly returned to Parent. To the extent there are losses with respect to such investments, or the Exchange Fund diminishes for other reasons below the level required to fully satisfy all of the payment obligations to be made in cash by the Exchange Agent hereunder, Parent shall promptly replace or restore the cash in the Exchange Fund so that the Exchange Fund is at all times maintained at a level sufficient for the Exchange Agent to fully satisfy such cash payment obligations. No investment losses resulting from investment of the Exchange Fund shall diminish the rights of any former holder of Eligible Units to receive the Merger Consideration as provided in this Agreement.

5.2Procedures for Surrender.

Any Certificate that has been so surrendered shall be cancelled by the Exchange Agent.

(b) With respect to Book-Entry Units not held through DTC (each, a “Non-DTC Book-Entry Unit”), as promptly as reasonably practicable after the Effective Time (and in any event within three Business Days thereafter), the Surviving Entity shall cause the Exchange Agent to mail to each holder of record of aNon-DTC Book-Entry Unit (i) a notice advising such holders of the effectiveness of the Merger; (ii) a statement reflecting the number of

-15-

whole shares of Parent Common Stock, if any, that such holder is entitled to receive pursuant to ARTICLE IV in the name of such record holder; and (iii) a check in the amount (after giving effect to any required Tax withholdings as provided in Section 5.8) of (A) any cash in lieu of fractional sharesplus (B) any unpaid dividends or other distributions that such holder has the right to receive pursuant to this ARTICLE V. Notwithstanding the foregoing, any holder of an Eligible Unit that is evidenced by both a Certificate and a book-entry account shall not receive the notice, statement and check contemplated by the immediately preceding sentence with respect to such Eligible Unit, but shall surrender the applicable Certificate in accordance with the procedures set forth in Section 5.2(a) to receive the Merger Consideration and any other amounts due under this Agreement with respect to such Eligible Unit, and no additional Merger Consideration or other amounts under this Agreement will accrue or be payable to the book-entry account for such Eligible Unit.

(c) With respect to Book-Entry Units held through DTC, Parent and the Partnership shall cooperate to establish procedures with the Exchange Agent and DTC to ensure that the Exchange Agent will transmit to DTC or its nominees as soon as reasonably practicable on or after the Closing Date, upon surrender of Eligible Units held of record by DTC or its nominees in accordance with DTC’s customary surrender procedures, the Merger Consideration, cash in lieu of fractional shares of Parent Common Stock, if any, and any unpaid dividends or other distributions, in each case, that such holder has the right to receive pursuant to this ARTICLE V.

(d) No interest will be paid or accrued on any amount payable for Eligible Units pursuant to this ARTICLE V.

5.3Distributions with Respect to Unsurrendered Certificates. All shares of Parent Common Stock to be issued pursuant to the Merger shall be deemed issued and outstanding as of the Effective Time and whenever a dividend or other distribution is declared by Parent in respect of the Parent Common Stock, the record date for which is at or after the Effective Time, that declaration shall include dividends or other distributions in respect of all shares issuable pursuant to this Agreement. Subject to Section 5.5, no dividends or other distributions in respect of shares of Parent Common Stock shall be paid to any holder with respect to any unsurrendered Certificate until the Certificate (or satisfaction of the conditions provided in Section 5.7 in lieu of a Certificate) is surrendered for exchange in accordance with this ARTICLE V. Subject to applicable Law, following such surrender, dividends or distributions with respect to the Parent Common Stock issued in exchange for Eligible Units in accordance with this ARTICLE V shall be paid to the holders of record of such Eligible Units, without interest, (a) promptly after the time of such surrender for any dividends or other distributions with a record date after the Effective Time but a payment date prior to surrender and (b) at the appropriate payment date for any dividends or other distributions payable with respect to shares of Parent Common Stock with a record date after the Effective Time and prior to surrender, but with a payment date subsequent to surrender.

-16-

5.4Transfers.

(a) From and after the Effective Time, there shall be no transfers on the stock transfer books of the Partnership of the Eligible Units that were outstanding immediately prior to the Effective Time. From and after the Effective Time, the holders of Certificates or Book-Entry Units shall cease to have any rights with respect to such Eligible Units except as otherwise provided herein or by applicable Law. If, after the Effective Time, Certificates are presented to the Surviving Entity for any reason, they shall be cancelled and exchanged as provided in this Agreement.

(b) With respect to Certificates, in the event of a transfer of ownership of any Certificate that is not registered in the transfer books of the Partnership as of the Effective Time, the proper number of shares of Parent Common Stock, together with a check for any cash (after giving effect to any required Tax withholdings as provided in Section 5.8) to be paid upon due surrender of the Certificate and any dividends or distributions in respect thereof, may be issued or paid to such a transferee if the Certificate is presented to the Exchange Agent, accompanied by all documents required to evidence and effect such transfer and to evidence that any applicable stock transfer Taxes have been paid or are not applicable, in each case, in form and substance, reasonably satisfactory to the Exchange Agent. Until surrendered as contemplated by this Section 5.4, each Certificate shall be deemed at any time after the Effective Time to represent only the right to receive the Merger Consideration, cash in lieu of fractional shares of Parent Common Stock, if any, and any unpaid dividends or other distributions, in each case, payable or issuable pursuant to this ARTICLE V.

(c) With respect toBook-Entry Units, payment of the Merger Consideration, cash in lieu of fractional shares of Parent Common Stock, if any, and any unpaid dividends or other distributions, in each case, payable or issuable pursuant to this ARTICLE V, shall only be made to the Person in whose name such Book-Entry Units are registered in the stock transfer books of the Partnership as of the Effective Time.

5.5Fractional Shares. Notwithstanding anything in this Agreement to the contrary, no fractional shares of Parent Common Stock will be issued upon the conversion of Common Units pursuant to Section 4.1. All fractional shares of Parent Common Stock that a holder of Eligible Units would be otherwise entitled to receive pursuant to Section 4.1, but for this Section 5.5, shall be aggregated and rounded to three decimal places, and such holder shall be entitled to receive an amount in cash, without interest, rounded down to the nearest cent, equal to the product of (a) the amount of the fractional share interest in a share of Parent Common Stock to which such holder would, but for this Section 5.5, be entitled under Section 4.1 and (b) an amount equal to the average of the volume-weighted average price per share of Parent Common Stock on the New York Stock Exchange as reported by Bloomberg L.P., or, if not reported therein, in another authoritative source mutually selected by Parent and the Partnership on the Trading Day immediately prior to the Effective Time for ten Trading Days ending on the fifth full Business Day immediately prior to the Closing Date. No holder of Eligible Units shall be entitled by virtue of the right to receive cash in lieu of fractional shares of Parent Common Stock described in this Section 5.5 to any dividends, distributions, voting rights or any other rights in respect of any fractional share of Parent Common Stock. The payment of cash in lieu of fractional shares of Parent Common Stock is not a separatelybargained-for consideration but merely represents a mechanicalrounding-off of the fractions in the exchange.

-17-

5.6Termination of Exchange Fund. Any portion of the Exchange Fund (including the proceeds of any investments of the Exchange Fund and any shares of Parent Common Stock) that remains unclaimed as of the date that is twelve months following the Effective Time shall be delivered to Parent. Any holder of Eligible Units who has not theretofore complied with this ARTICLE V shall thereafter look only to Parent for delivery of the Merger Consideration, cash in lieu of fractional shares of Parent Common Stock, if any, and any unpaid dividends or other distributions, in each case, that such holder has the right to receive pursuant to this ARTICLE V, in each case, without any interest thereon. Notwithstanding the foregoing, none of the Surviving Entity, Parent, the Exchange Agent or any other Person shall be liable to any former holder of Common Units for any amount properly delivered to a public official pursuant to applicable abandoned property, escheat or similar Laws. Any portion of the Exchange Fund which remains undistributed to the holders of Eligible Units immediately prior to the time at which the Exchange Fund would otherwise escheat to, or become property of, any Governmental Entity, shall, to the extent permitted by Laws, become the property of Parent, free and clear of all claims or interest of any Person previously entitled thereto.

5.7Lost, Stolen or Destroyed Certificates. In the event that any Certificate shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the Person claiming such Certificate to be lost, stolen or destroyed and the posting by such Person of a bond in customary amount and upon such terms as may be required as indemnity against any claim that may be made against it with respect to such Certificate, the Exchange Agent will issue in exchange for such lost, stolen or destroyed Certificate, the Merger Consideration, cash in lieu of fractional shares of Parent Common Stock, if any, and any unpaid dividends or other distributions, in each case, payable or issuable pursuant to this ARTICLE V, had such lost, stolen or destroyed Certificate been surrendered.

5.8Withholding Rights. Each of Parent, SETLLC, Merger Sub, the Partnership, the Exchange Agent and the Surviving Entity shall be entitled to deduct and withhold from the consideration otherwise payable pursuant to this Agreement, without duplication, such amounts, which may include shares of Parent Common Stock, as Parent, SETLLC, Merger Sub, the Partnership, the Exchange Agent and the Surviving Entity reasonably deem to be 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. To the extent that amounts are so withheld by Parent, SETLLC, Merger Sub, the Partnership, the Exchange Agent or the Surviving Entity, as applicable, such withheld amounts (a) shall be timely remitted by Parent, SETLLC, Merger Sub, the Partnership, the Exchange Agent or the Surviving Entity, as applicable, to the applicable Governmental Entity, and (b) to the extent such withheld amounts are remitted to the appropriate Governmental Entity, shall be treated for all purposes of this Agreement as having been paid to the holder of Common Units in respect of which such deduction and withholding was made by Parent, SETLLC, Merger Sub, the Partnership, the Exchange Agent or the Surviving Entity, as applicable. If withholding is taken in shares of Parent Common Stock, Parent, SETLLC, Merger Sub, the Partnership, the Surviving Entity and the Exchange Agent, as applicable, shall be treated as having sold such consideration for an amount of cash equal to the fair market value of such consideration at the time of such deemed sale and paid such cash proceeds to the appropriate Governmental Entity.

Nothing in this Section 5.9 shall be construed to permit the Parties to take any action except to the extent consistent with, and not otherwise prohibited by, the terms of this Agreement.

5.10No Dissenters’ Rights. No dissenters’ or appraisal rights shall be available with respect to the Merger or the other Transactions.

5.11Termination of Partnership Equity Plan.

(a) Prior to the Effective Time, the Partnership and the General Partner shall take all actions necessary to terminate the Partnership Long-Term Incentive Plan, such termination to be effective at the Effective Time, and from and after the Effective Time, the Partnership Long-Term Incentive Plan shall be terminated and no equity awards or other rights with respect to Common Units or other Partnership Interests shall be granted or be outstanding thereunder.

11.5Specific Performance.

(a) Each of the Parties acknowledges and agrees that the rights of each Party to consummate the Transactions are special, unique and of extraordinary character and that if for any reason any of the provisions of this Agreement are not performed in accordance with their specific terms or are otherwise breached (including by a Party’s failing to take such actions as are required of such Party hereunder in order to consummate the Transactions), immediate and irreparable harm or damage would be caused for which money damages would not be an adequate remedy. Accordingly, each Party agrees that, in addition to any other available remedies a Party may have in equity or at law, each Party shall be entitled to enforce specifically the terms and provisions of this Agreement and to obtain an injunction restraining any breach or violation or threatened breach or violation of the provisions of this Agreement in the Chosen Courts,provided that such Party seeking specific performance, injunction or other equitable remedy pursuant to this Section 11.5 is not in material default under this Agreement.

In the event that any Proceeding should be brought in equity to enforce the provisions of this Agreement, no Party shall allege, and each Party hereby waives the defense, that there is an adequate remedy at law.

(b) To the extent any Party brings a Proceeding to enforce specifically the performance of the terms and provisions of this Agreement (other than a Proceeding to specifically enforce any provision that expressly survives termination of this Agreement) when expressly available to such Party pursuant to the terms of this Agreement, the Outside Date shall automatically be extended to (i) the twentieth Business Day following the resolution of such Proceeding, or (ii) such other time period established by the court presiding over such Proceeding.

11.7Entire Agreement.

(a) This Agreement (including any exhibits hereto), the Partnership Disclosure Letter and the Parent Disclosure Letter constitute the entire agreement among the Parties with respect to the subject matter of this Agreement and supersede all prior and contemporaneous agreements, negotiations, understandings and representations and warranties, whether oral or written, with respect to such matters.

(b) Each Party acknowledges the provisions set forth in Section 6.16 (No Other Representations or Warranties) and Section 7.15 (No Other Representations or Warranties) and, without limiting such provisions, additionally acknowledges and agrees that, except for the representations and warranties expressly set forth in this Agreement, the Partnership Disclosure Letter, the Parent Disclosure Letter and any certificates delivered by any Party pursuant to this Agreement: (i) no Party has made or is making any other representations, warranties, statements, information or inducements; (ii) no Party has relied on or is relying on any other representations, warranties, statements, information or inducements; and (iii) each Party hereby disclaims reliance on any other representations, warranties, statements, information or inducements provided to such Party by the other Party, in each case for clauses (i), (ii) and (iii), oral or written, express or implied, or as to the accuracy or completeness of any statements or other information, made by, or made available by, itself or any of its Representatives, in each case with respect to, or in connection with, the negotiation, execution or delivery of this Agreement, any instrument or other document delivered pursuant to this Agreement or the Transactions, and notwithstanding the distribution, disclosure or other delivery to the other or the other’s Representatives of any documentation or other information with respect to any one or more of the foregoing, and waives any claims or causes of action relating thereto.

11.8Third-Party Beneficiaries. Except for, from and after the Effective Time, the Indemnified Parties with respect to the provisions of Section 8.8 (Indemnification; Directors’ and Officers’ Insurance), the Parties hereby agree that their respective representations, warranties and covenants set forth in this Agreement are solely for the benefit of the other Parties on the terms and subject to the conditions set forth in this Agreement, and this Agreement is not

-51-

intended to, and does not, confer upon any Person other than the Parties and their respective successors, legal representatives and permitted assigns any rights or remedies, express or implied, hereunder, including the right to rely upon the representations and warranties set forth in this Agreement. The representations and warranties in this Agreement are the product of negotiations among the Parties. Any inaccuracies in such representations and warranties are subject to waiver by the Parties in accordance with Section 11.2 without notice or liability to any other Person. In some instances, the representations and warranties in this Agreement may represent an allocation among the Parties of risks associated with particular matters regardless of the knowledge of any of the Parties. Consequently, Persons other than the Parties may not rely upon the representations and warranties in this Agreement as characterizations of actual facts or circumstances as of the date of this Agreement or as of any other date.

11.9Non-Recourse. Unless expressly agreed to otherwise by the Parties in writing, this Agreement may only be enforced against, and any Proceeding in connection with, arising out of or otherwise resulting from this Agreement, any instrument or other document delivered pursuant to this Agreement or the Transactions may only be brought against the Persons expressly named as Parties (or any of their respective successors, legal representatives and permitted assigns) and then only with respect to the specific obligations set forth herein with respect to such Party. No past, present or future director, employee (including any officer), incorporator, manager, member, partner, stockholder, unitholder, other equity holder or persons in a similar capacity, controlling person, Affiliate or other Representative of any Party or of any Affiliate of any Party, or any of their respective successors, Representatives and permitted assigns shall have any liability or other obligation for any obligation of any Party under this Agreement or for any Proceeding in connection with, arising out of or otherwise resulting from this Agreement, any instrument or other document delivered pursuant to this Agreement or the Transactions;provided,however, that nothing in this Section 11.9 shall limit any liability or other obligation of the Parties for breaches of the terms and conditions of this Agreement.

11.10Fulfillment of Obligations. Whenever this Agreement requires a Subsidiary of Parent to take any action, such requirement shall be deemed to include an undertaking on the part of Parent to cause such Subsidiary to take such action. Whenever this Agreement requires a Subsidiary of the Partnership to take any action, such requirement shall be deemed to include an undertaking on the part of the Partnership to cause such Subsidiary to take such action and, after the Effective Time, on the part of the Surviving Entity to cause such Subsidiary to take such action.

11.11Partnership Board Consent. Unless otherwise expressly set forth in this Agreement, whenever a determination, decision, approval or consent of the Partnership, the General Partner or the Partnership Board is required pursuant to this Agreement, such determination, decision, approval or consent must be authorized by the Partnership Board;provided,however, that the Partnership Board may not take or authorize any such action unless it has been approved in writing by the Conflicts Committee.

11.12Severability. The provisions of this Agreement shall be deemed severable and the illegality, invalidity or unenforceability of any provision shall not affect the legality, validity or enforceability of the other provisions of this Agreement. If any provision of this Agreement, or the application of such provision to any Person or any circumstance, is illegal,

-52-

invalid or unenforceable, (a) a suitable and equitable provision shall be substituted therefor in order to carry out, so far as may be legal, valid and enforceable, the intent and purpose of such legal, invalid or unenforceable provision, and (b) the remainder of this Agreement and the application of such provision to other Persons or circumstances shall not be affected by such illegality, invalidity or unenforceability, nor shall such illegality, invalidity or unenforceability affect the legality, validity or enforceability of such provision, or the application of such provision, in any other jurisdiction.

11.13Successors and Assigns. This Agreement shall be binding upon and inure to the benefit of the Parties (and any of their respective successors, legal representatives and permitted assigns). No Party may assign any of its rights or delegate any of its obligations under this Agreement, in whole or in part, by operation of Law or otherwise, without the prior written consent of the other Parties, except as provided for in Section 11.10, and any attempted or purported assignment or delegation in violation of this Section 11.13 shall be null and void;provided,however, that Parent may designate another wholly owned direct or indirect Subsidiary to be a constituent corporation in the Merger in lieu of Merger Sub, so long as Parent provides the Partnership with advance written notice thereof, in which event all references to Merger Sub in this Agreement shall be deemed references to such other wholly owned Subsidiary of Parent, except that all representations and warranties made in this Agreement with respect to Merger Sub as of the date of this Agreement shall be deemed representations and warranties made with respect to such other wholly owned Subsidiary as of the date of such designation;provided, further, that any such designation shall not prevent or materially impede or materially delay the consummation of the Transactions or otherwise adversely affect the rights of the unitholders of the Partnership under this Agreement in any material respect.
