AGREEMENT AND PLAN OF MERGER

This AGREEMENT AND PLAN OF MERGER, dated as of October 9, 2013 (this “Agreement”), is by and among PVR Partners, L.P., a Delaware limited partnership (“MLP”), PVR GP, LLC, a Delaware limited liability company and the general partner of MLP (“MLP GP” and, together with MLP, the “MLP Entities”), Regency Energy Partners LP, a Delaware limited partnership (“Parent”), Regency GP LP, a Delaware limited partnership and the general partner of Parent (“Parent GP”), and RVP LLC, a Delaware limited liability company and a wholly owned Subsidiary of Parent (“Merger Sub” and, together with Parent and Parent GP, the “Parent Entities”).

W I T N E S S E T H:

WHEREAS, the board of directors of MLP GP (the “MLP GP Board”) has unanimously (i) determined that it is in the best interests of MLP and its Limited Partners, and declared it advisable, to enter into this Agreement, (ii) approved the execution, delivery and performance of this Agreement and the transactions contemplated hereby and (iii) resolved to submit the Agreement to a vote of the Limited Partners and recommend adoption of this Agreement by the Limited Partners; and

WHEREAS, Parent, in its capacity as the sole managing member of Merger Sub, and the board of directors (the “Parent Managing GP Board”) of Regency GP LLC, a Delaware limited liability company and the general partner of Parent GP (“Parent Managing GP”), have each approved and declared advisable this Agreement and the transactions contemplated hereby.

NOW, THEREFORE, in consideration of the representations, warranties, covenants and agreements contained in this Agreement, and intending to be legally bound, the parties agree as follows:

ARTICLE I

The Merger

Section 1.1 The Merger. Upon the terms and subject to the conditions set forth in this Agreement, and in accordance with the DRULPA and the DLLCA, at the Effective Time, Merger Sub shall be merged with and into MLP (the “Merger”), the separate limited liability company existence of Merger Sub will cease, and MLP will continue its existence as a limited partnership under Delaware law as the surviving entity in the Merger (the “Surviving Entity”).

Section 1.2 Closing. Subject to the provisions of Article VI, the closing of the Merger (the “Closing”) shall take place at the offices of Baker Botts L.L.P., 2001 Ross Avenue, Dallas, Texas 75201 at 9:00 A.M., local time, on the second business day after the satisfaction or waiver of the conditions set forth in Article VI (other than conditions that by their nature are to be satisfied at the Closing, but subject to the satisfaction or waiver of those conditions), or at such other place, date and time as MLP and Parent shall agree. The date on which the Closing actually occurs is referred to as the “Closing Date.”

Section 1.3 Effective Time. Subject to the provisions of this Agreement, at the Closing, MLP will cause a certificate of merger, executed in accordance with the relevant provisions of the DRULPA and the DLLCA (the “Certificate of Merger”) to be duly filed with the Secretary of State of the State of Delaware. The Merger will become effective at such time as the Certificate of Merger has been duly filed with the Secretary of State of the State of Delaware or at such later date or time as may be agreed by MLP and Parent in writing and specified in the Certificate of Merger (the effective time of the Merger being hereinafter referred to as the “Effective Time”).

Section 1.4 Effects of the Merger. The Merger shall have the effects set forth in the applicable provisions of the DRULPA and the DLLCA.

Section 1.5 Organizational Documents of the Surviving Entity.

(a) At the Effective Time, the certificate of limited partnership of MLP as in effect immediately prior to the Effective Time shall remain unchanged and shall be the certificate of limited partnership of the Surviving Entity from and after the Effective Time, and thereafter may be amended as provided therein or by Law, in each case consistent with the obligations set forth in Section 5.8.

(b) The MLP Partnership Agreement shall, by virtue of the Merger and the Certificate of Merger, be amended and restated in its entirety as set forth in Exhibit A hereto, and thereafter may be amended as provided therein or by Law, in each case consistent with the obligations set forth in Section 5.8.

ARTICLE II

Effect on Units

Section 2.1 Effect of Merger. At the Effective Time, by virtue of the Merger and without any action on the part of MLP GP, MLP, Parent GP, Parent, Merger Sub or the holder of any securities of MLP or Merger Sub:

(a) Conversion of Common Units and Class B Units. Subject to Section 2.1(c), Section 2.2(h) and Section 2.4, each Common Unit and each Class B Unit issued and outstanding or deemed issued and outstanding in accordance with Section 2.3 as of immediately prior to the Effective Time shall be converted into the right to receive (i) an amount of cash equal to the difference (if positive) between (x) the Annualized MLP Distribution minus (y) the Annualized Adjusted Parent Distribution (the “Cash Consideration”) and (ii) 1.020 (the “Exchange Ratio”) Parent Units (the “Unit Consideration” and, together with the Cash Consideration, the “Merger Consideration”).

(b) Limited Partner Interests of the Surviving Entity. At the Effective Time, by virtue of the Merger and without any action on the part of Parent, the membership interests in Merger Sub issued and outstanding immediately prior to the Effective Time shall be converted into a 100% limited partner interest in MLP (as the Surviving Entity). At the Effective Time, the books and records of MLP shall be revised to reflect the admission of Parent as a Limited Partner of MLP and the simultaneous withdrawal of all other Limited Partners of MLP.

(c) Cancellation of MLP-Owned Units and Parent-Owned Units. Any MLP Securities that are owned immediately prior to the Effective Time by MLP or any Subsidiary of MLP, and any MLP Securities owned immediately prior to the Effective Time by Parent or any Subsidiary of Parent, shall be automatically canceled and shall cease to exist and no consideration shall be delivered in exchange for such canceled MLP Securities.

(d) Certificates. As of the Effective Time, all Common Units and Class B Units converted into the Merger Consideration pursuant to this Article II shall no longer be outstanding and shall automatically be canceled and shall cease to exist, and each holder of a certificate (or evidence of units in book-entry form) that immediately prior to the Effective Time represented any such Common Units or Class B Units (a “Certificate”) shall cease to have any rights with respect thereto, except the right to receive the Merger Consideration, any distributions to which such holder is entitled pursuant to Section 2.2(g) and cash in lieu of any fractional Parent Units to which such holder is entitled pursuant to Section 2.2(h), in each case to be issued or paid in consideration therefor upon surrender of such Certificate in accordance with Section 2.2(c), without interest, and the right to be admitted as a Parent Limited Partner. Parent GP hereby consents to the admission (as a Parent Limited Partner) of each Unitholder who is issued Parent Units in exchange for such Unitholder’s Common Units or Class B Units in accordance with this Article II, upon the proper surrender of the Certificate representing such Common Units or Class B Units. Upon such surrender of the Certificate (or upon a waiver of the requirement to surrender a Certificate granted by Parent GP in its sole discretion) and the recording of the name of such Person as a limited partner of Parent on the books and records of Parent, such Person shall automatically and effective as of the Effective Time be admitted as a Parent Limited Partner and be bound by the Parent Partnership Agreement as such. By its surrender of a Certificate, or by its acceptance of Parent Units, a Unitholder confirms its agreement to be bound by all of the terms and conditions of the Parent Partnership Agreement.

Section 2.2 Exchange of Certificates.

(a) Exchange Agent. Prior to the Closing Date, Parent shall appoint an exchange agent reasonably acceptable to MLP (the “Exchange Agent”) for the purpose of exchanging Certificates for the Merger Consideration. As soon as reasonably practicable after the Effective Time, but in no event more than three business days following the Effective Time, Parent will send, or will cause the Exchange Agent to send, to each holder of record of Common Units and Class B Units as of the Effective Time (and, to the extent commercially practicable, to make available for collection by hand, during customary business hours commencing immediately after the Effective Time, if so elected by such holder of record), whose Common Units and Class B Units, were converted into the right to receive the Merger Consideration, a letter of transmittal (which shall specify that the delivery shall be effected, and risk of loss and title shall pass, only upon proper delivery of the Certificates (or effective affidavits of loss in lieu thereof) to the Exchange Agent) in such forms as MLP and Parent may reasonably agree, including, as applicable, instructions for use in effecting the surrender of Certificates (or effective affidavits of loss in lieu thereof) to the Exchange Agent in exchange for the Merger Consideration and cash in lieu of any fractional Parent Units payable pursuant to Section 2.2(h).

(b) Deposit. At or prior to the Closing, Parent shall cause to be deposited with the Exchange Agent, in trust for the benefit of the holders of Common Units, Class B Units, Restricted Units, Phantom Units (and distribution equivalent rights) and Deferred Common Units, an amount of Parent Units (which shall be in non-certificated book-entry form) and an amount of cash in U.S. dollars sufficient to be issued and paid pursuant to Section 2.1(a)(i) and Section 2.3(a), payable upon due surrender of the Certificates or other evidence of Restricted Units, Phantom Units (and distribution equivalent rights) and Deferred Common Units (or effective affidavits of loss in lieu thereof) pursuant to the provisions of this Article II. Following the Effective Time, Parent agrees to make available to the Exchange Agent, from time to time as needed, cash in U.S. dollars sufficient to pay any distributions pursuant to Section 2.2(g) and any Parent Units sufficient to pay any Merger Consideration, in each case, that may be payable from time to time following the Effective Time. All cash and book-entry units representing Parent Units deposited with the Exchange Agent or representing unit proceeds obtained pursuant to Section 2.2(h) shall be referred to in this Agreement as the “Exchange Fund.” The Exchange Agent shall, pursuant to irrevocable instructions, deliver the Merger Consideration contemplated to be issued or paid pursuant to this Article II out of the Exchange Fund. The Exchange Fund shall not be used for any other purpose. The Exchange Agent shall invest any cash included in the Exchange Fund as directed by Parent; provided that (i) no such investment or losses thereon shall affect the Merger Consideration payable to holders of Common Units, Class B Units, Restricted Units, Phantom Units (and distribution equivalent rights) or Deferred Common Units entitled to receive such consideration or cash in lieu of fractional interests, or in respect of distribution equivalent rights, pursuant to Section 2.3(a) and Parent shall promptly cause to be provided additional funds to the Exchange Agent for the benefit of holders of Common Units, Class B Units, Restricted Units, Phantom Units (and distribution equivalent rights) or Deferred Common Units entitled to receive such consideration in the amount of any such losses; and (ii) such investments shall be in short-term obligations of the United States of America with maturities of no more than 30 days.

(c) Exchange. Each holder of Common Units and Class B Units that have been converted into the right to receive the Merger Consideration, upon surrender to the Exchange Agent of a properly completed letter of transmittal, duly executed and completed in accordance with the instructions thereto, a Certificate (as applicable) and such other documents as may reasonably be required by the Exchange Agent, will be entitled to receive in exchange therefor (i) the number of Parent Units representing, in the aggregate, the whole number of Parent Units that such holder has the right to receive in accordance with the provisions of this Article II and/or (ii) a check denominated in U.S. dollars in the amount of cash that such holder has the right to receive pursuant to this Article II, including the Cash Consideration. The Merger Consideration shall be paid as promptly as practicable by mail after receipt by the Exchange Agent of the Certificate and letter of transmittal in accordance with the foregoing. No interest shall be paid or accrued on any Merger Consideration, cash in lieu of fractional Parent Units or in respect of distribution equivalent rights or on any unpaid distributions payable to holders of Certificates. Until so surrendered, each such Certificate shall, after the Effective Time, represent for all purposes only the right to receive such Merger Consideration. The Merger Consideration paid upon surrender of Certificates shall be deemed to have been paid in full satisfaction of all rights pertaining to the Common Units or Class B Units, as the case may be, formerly represented by such Certificates.

(d) Other Payees. If any cash payment is to be made to a Person other than the Person in whose name the applicable surrendered Certificate is registered, it shall be a condition of such payment that the Person requesting such payment shall pay any transfer or other similar Taxes required by reason of the making of such cash payment to a Person other than the registered holder of the surrendered Certificate or shall establish to the satisfaction of the Exchange Agent that such Tax has been paid or is not payable. If any portion of the Merger Consideration is to be registered in the name of a Person other than the Person in whose name the applicable surrendered Certificate is registered, it shall be a condition to the registration thereof that the surrendered Certificate shall be properly endorsed or otherwise be in proper form for transfer and that the Person requesting such delivery of the Merger Consideration shall pay to the Exchange Agent any transfer or other similar Taxes required as a result of such registration in the name of a Person other than the registered holder of such Certificate or establish to the satisfaction of the Exchange Agent that such Tax has been paid or is not payable.

(e) No Further Transfers. From and after the Effective Time, there shall be no further registration on the books of MLP of transfers of Common Units or Class B Units. From and after the Effective Time, the holders of Certificates representing Common Units or Class B Units outstanding immediately prior to the Effective Time shall cease to have any rights with respect to such Common Units or Class B Units, except as otherwise provided in this Agreement or by applicable Law. If, after the Effective Time, Certificates are presented to the Exchange Agent or Parent, they shall be canceled and exchanged for the consideration provided for, and in accordance with the procedures set forth, in this Article II.

(f) Termination of Exchange Fund. Any portion of the Exchange Fund that remains unclaimed by the holders of Common Units or Class B Units 12 months after the

Effective Time shall be returned to Parent, upon demand, and any such holder who has not exchanged his, her or its Common Units or Class B Units for the Merger Consideration in accordance with this Section 2.2 prior to that time shall thereafter look only to Parent for delivery of the Merger Consideration in respect of such holder’s Common Units or Class B Units. Notwithstanding the foregoing, Parent, Merger Sub and MLP shall not be liable to any holder of Common Units or Class B Units for any Merger Consideration duly delivered to a public official pursuant to applicable abandoned property Laws. Any Merger Consideration remaining unclaimed by holders of Common Units or Class B Units immediately prior to such time as such amounts would otherwise escheat to, or become property of, any Governmental Authority shall, to the extent permitted by applicable Law, become the property of Parent free and clear of any claims or interest of any Person previously entitled thereto.

(g) Distributions. No distributions with respect to Parent Units issued in the Merger shall be paid to the holder of any unsurrendered Certificates until such Certificates are surrendered as provided in this Section 2.2. Following such surrender, subject to the effect of escheat, Tax or other applicable Law, there shall be paid, without interest, to the record holder of the Parent Units, if any, issued in exchange therefor (i) at the time of such surrender, all distributions payable in respect of any such Parent Units with a record date after the Effective Time and a payment date on or prior to the date of such surrender and not previously paid and (ii) at the appropriate payment date, the distributions payable with respect to such Parent Units with a record date after the Effective Time but with a payment date subsequent to such surrender. For purposes of distributions in respect of Parent Units, all Parent Units to be issued pursuant to the Merger shall be entitled to distributions pursuant to the immediately preceding sentence as if issued and outstanding as of the Effective Time.

(h) No Fractional Units. No certificates or scrip representing fractional Parent Units shall be issued upon the surrender for exchange of Certificates. Notwithstanding any other provision of this Agreement, each holder of Common Units or Class B Units converted pursuant to the Merger who would otherwise have been entitled to receive a fraction of a Parent Unit (after taking into account all Certificates (or effective affidavits of loss in lieu thereof) delivered by such holder) shall be entitled to receive, from the Exchange Agent in accordance with the provisions of this Section 2.2(h), a cash payment, without interest, in lieu of such fractional units representing such holder’s proportionate interest, if any, in the proceeds from the sale by the Exchange Agent (reduced by reasonable and customary fees of the Exchange Agent attributable to such sale) (as so reduced, the “unit proceeds”) in one or more transactions of a number of Parent Units, such number equal to the excess of (i) the aggregate number of Parent Units to be delivered to the Exchange Agent by Parent pursuant to Section 2.2(b) over (ii) the aggregate number of whole Parent Units to be distributed to the holders of Certificates pursuant to Section 2.2(c) (such excess, the “Excess Units”). The parties acknowledge that payment of the cash unit proceeds in lieu of issuing certificates or scrip for fractional units was not separately bargained-for consideration but merely represents a mechanical rounding off for purposes of avoiding the expense and inconvenience to Parent that would otherwise be caused by the issuance of fractional units. As soon as practicable after the Effective Time, the Exchange Agent, as agent for the holders of Common Units or Class B Units that would otherwise receive fractional Parent Units, shall sell the Excess Units at then-prevailing prices on the NYSE in the manner provided in this Section 2.2(h) and such sales shall be executed in round lots to the extent practicable.

Until the unit proceeds of such sale or sales have been distributed to the holders of such Common Units or Class B Units, or the Exchange Fund is terminated, the Exchange Agent shall hold such unit proceeds in trust for the benefit of the holders of such Common Units and Class B Units (the “Fractional Unit Proceeds”). The Exchange Agent shall determine the portion of the Fractional Unit Proceeds to which each holder of such Common Units and Class B Units shall be entitled, if any, by multiplying the amount of the aggregate unit proceeds comprising the Fractional Unit Proceeds by a fraction, the numerator of which is the amount of the fractional unit interest to which such holder of such Common Units or Class B Units would otherwise be entitled and the denominator of which is the aggregate amount of fractional unit interests to which all holders of such Common Units would otherwise be entitled.

(i) Lost, Stolen or Destroyed Certificates. If 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, if required by Parent, the posting by such Person of a bond, in such reasonable amount as Parent may direct, 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 to be paid in respect of the Common Units represented by such Certificate as contemplated by this Article II.

(j) Withholding Taxes. Parent, Merger Sub and the Exchange Agent shall deduct and withhold from the consideration otherwise payable pursuant to this Agreement to a holder of Common Units, Class B Units, Restricted Units, Phantom Units (and any distribution equivalent rights) and Deferred Common Units such amounts as are required to be deducted and withheld with respect to the making of such payment under the Internal Revenue Code of 1986, as amended (the “Code”), and the rules and regulations promulgated thereunder, or under any provision of applicable state, local or foreign Tax Law (and to the extent deduction and withholding is required, such deduction and withholding shall be taken in Parent Units). To the extent amounts are so withheld and paid over to the appropriate Tax authority, such withheld amounts shall be treated for the purposes of this Agreement as having been paid to the former holder of the Common Units, Class B Units, Restricted Units, Phantom Units (and distribution equivalent rights) and Deferred Common Units, as applicable, in respect of whom such withholding was made. If withholding is taken in Parent Units, Parent and the Exchange Agent 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 Tax authority.

(k) Tax Characterization of Merger and Cash Received. MLP and Parent each acknowledges and agrees that for federal income Tax purposes the transactions consummated pursuant to this Agreement will be treated as an “assets-over” partnership merger transaction under Treasury Regulations Sections 1.708-1(c)(1) and 1.708-1(c)(3)(i), whereby MLP will be the terminating partnership and Parent will be the resulting partnership. As a result, the transactions consummated pursuant to this Agreement shall be treated for U.S. federal income Tax purposes as a contribution of all of the assets of MLP to Parent in exchange for the Merger Consideration, the cash received in lieu of fractional Parent Units and the assumption of liabilities. To the maximum extent possible, the Cash Consideration and any cash received in lieu of fractional Parent Units shall be treated as a reimbursement of preformation capital

expenditures described in Treasury Regulation Section 1.707-4(d). To the extent the Cash Consideration and any cash received in lieu of fractional Parent Units exceeds the amount that can be so treated, such excess cash will be treated as proceeds of a disguised sale transaction described in Section 707(a)(2)(B) of the Code (a “Disguised Sale”). Each of MLP and Parent agrees to prepare and file all U.S. federal income Tax Returns in accordance with the foregoing and shall not take any position inconsistent therewith on any such Tax Return, or in the course of any audit, litigation or other proceeding with respect to U.S. federal income Taxes, except as otherwise required by applicable Laws following a final determination by a court of competent jurisdiction or other final administrative decision by an applicable Governmental Authority.

(a) Treatment of Phantom Units. Except as otherwise expressly provided in the original grant terms of a particular award, each Phantom Unit that is outstanding immediately prior to the Effective Time shall, as of the Effective Time, automatically and without any action on the part of the holder thereof, vest in full (in the case of performance-based Phantom Units, based on achievement of target level of performance) and the restrictions with respect thereto shall lapse, and each Common Unit deemed to be issued in settlement thereof shall be deemed issued and outstanding as of immediately prior to the Effective Time and otherwise subject to the terms and conditions of this Agreement (including Sections 2.1 and 2.2). In addition, any then-accumulated distribution equivalents payable pursuant to distribution equivalent rights with respect to each Phantom Unit that vests pursuant to this Section 2.3(a) shall, as of the Effective Time, automatically and without any action on the part of the holder thereof, vest in full and shall become immediately payable in cash.

Each Restricted Unit that is outstanding immediately prior to the Effective Time shall, as of the Effective Time, automatically and without any action on the part of the holder thereof, vest in full and the restrictions with respect thereto shall lapse, and each Restricted Unit shall be treated as an issued and outstanding Common Unit as of immediately prior to the Effective Time and otherwise subject to the terms and conditions of this Agreement (including Sections 2.1 and 2.2).

Restrictions with respect to each Deferred Common Unit that is outstanding immediately prior to the Effective Time shall, as of the Effective Time, automatically and without any action on the part of the holder thereof, lapse, and each Deferred Common Unit shall be treated as an issued and outstanding Common Unit as of immediately prior to the Effective Time and otherwise subject to the terms and conditions of this Agreement (including Sections 2.1 and 2.2).

Section 2.5 No Dissenters’ Rights. No dissenters’ or appraisal rights shall be available with respect to the Merger or the other transactions contemplated hereby.

(c) Parent has established and maintains internal control over financial reporting and disclosure controls and procedures (as such terms are defined in Rule 13a-15 and Rule 15d-15 under the Exchange Act); such disclosure controls and procedures are designed to ensure that material information relating to Parent, including its consolidated Subsidiaries, required to be disclosed by Parent in the reports that it files or submits under the Exchange Act is accumulated and communicated to Parent’s principal executive officer and its principal financial officer to allow timely decisions regarding required disclosure; and such disclosure controls and procedures are effective to ensure that information required to be disclosed by Parent in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in SEC rules and forms.

not material, that involves management or other employees who have a significant role in Parent’s internal controls.

The management of Parent has completed its assessment of the effectiveness of Parent’s internal control over financial reporting in compliance with the requirements of Section 404 of the Sarbanes Oxley Act for the year ended December 31, 2012, and such assessment concluded that such controls were effective. To the Knowledge of Parent, as of the date of this Agreement, there are no facts or circumstances that would prevent its principal executive officer and principal financial officer from giving the certifications and attestations required pursuant to the rules and regulations adopted pursuant to Section 404 of the Sarbanes Oxley Act, without qualification, when next due.

Section 5.3 No Solicitation by MLP; Etc.

(a) MLP shall, and shall cause its Subsidiaries and use reasonable best efforts to cause MLP’s and its Subsidiaries’ respective directors, officers, employees, investment bankers, financial advisors, attorneys, accountants, agents and other representatives (collectively, “Representatives”) to, immediately cease and cause to be terminated any discussions or negotiations with any Person conducted heretofore with respect to an Alternative Proposal, request the return or destruction of all confidential information previously provided to such parties by or on behalf of MLP or its Subsidiaries and immediately prohibit any access by any Person (other than Parent and its Representatives) to any physical or electronic data room relating to a possible Alternative Proposal. Except as permitted by this Section 5.3, (x) MLP shall not, and shall cause its Subsidiaries and use reasonable best efforts to cause its Representatives not to, directly or indirectly (i) solicit, initiate, knowingly facilitate, knowingly encourage (including by way of furnishing confidential information) or knowingly induce or take any other action intended to lead to any inquiries or any proposals that constitute the submission of an Alternative Proposal, (ii) grant approval to any Person under clause (iii) of the provision in the definition of “Outstanding” in the MLP Partnership Agreement, (iii) except for a confidentiality agreement permitted pursuant to Section 5.3(b), enter into any confidentiality agreement, merger agreement, letter of intent, agreement in

principle, unit purchase agreement, asset purchase agreement or unit exchange agreement, option agreement or other similar agreement relating to an Alternative Proposal (an “Acquisition Agreement”), or (iv) withdraw, modify or qualify, or propose publicly to withdraw, modify or qualify, in a manner adverse to Parent, the MLP Board Recommendation or publicly recommend the approval or adoption of, or publicly approve or adopt, or propose to publicly recommend, approve or adopt, any Alternative Proposal and (y) within five business days of receipt of a written request of Parent following the receipt by MLP of any Alternative Proposal, MLP shall publicly reconfirm the MLP Board Recommendation; provided that, in the event that Parent requests such public reconfirmation of the MLP Board Recommendation, then MLP may not unreasonably withhold, delay (beyond the five business day period) or condition the public reconfirmation of the MLP Board Recommendation and provided further that Parent shall not be permitted to make such request on more than one occasion in respect of each Alternative Proposal and each material modification to an Alternative Proposal, if any (the taking of any action described in clause (x)(iv) or the failure to take the action described in clause (y) being referred to as an “Adverse Recommendation Change”). Without limiting the foregoing, it is understood that any violation of the foregoing restrictions by MLP’s Subsidiaries or Representatives shall be deemed to be a breach of this Section 5.3 by MLP unless such violation is committed without the Knowledge of MLP and MLP uses its reasonable best efforts to promptly cure such violation once MLP is made aware of such violation.

(b) Notwithstanding anything to the contrary contained in Section 5.3(a), if at any time following the date of this Agreement and prior to obtaining the MLP Unitholder Approval, (i) MLP has received a written Alternative Proposal that the MLP GP Board believes is bona fide, (ii) the MLP GP Board, after consultation with its financial advisors and outside legal counsel, determines in good faith that such Alternative Proposal constitutes or could reasonably be expected to lead to or result in a Superior Proposal and (iii) such Alternative Proposal did not result from a material breach of this Section 5.3, then MLP may, subject to clauses (x) and (y) below, (A) furnish information, including confidential information, with respect to MLP and its Subsidiaries to the Person making such Alternative Proposal and (B) participate in discussions or negotiations regarding such Alternative Proposal; provided that (x) MLP will not, and will use reasonable best efforts to cause its Representatives not to, disclose any non-public information to such Person unless MLP has, or first enters into, a confidentiality agreement with such Person with confidentiality provisions and “standstill” provisions that are not less restrictive to such Person than the provisions of the Parent Confidentiality Agreement are to Parent (provided that the standstill provisions of such confidentiality agreement may permit such Person to make a non-public Alternative Proposal to MLP GP Board) and (y) MLP will provide to Parent non-public information about MLP or its Subsidiaries that was not previously provided or made available to Parent prior to or substantially concurrently with providing or making available such non-public information to such other Person. If MLP desires to waive any of the standstill provisions of any confidentiality agreement entered into with another Person pursuant to the immediately preceding sentence, MLP shall give written notice of the specific aspect of the standstill provisions desired to be waived and thereafter shall be permitted to waive such provisions, which waiver shall constitute a waiver of the standstill provisions in Section 9 of the Parent Confidentiality Agreement in the same manner and to the same extent as such provisions are waived with respect to such Person.

(c) In addition to the other obligations of MLP set forth in this Section 5.3, MLP shall promptly advise Parent, orally and in writing, and in no event later than 24 hours after receipt, if any proposal, offer, inquiry or other contact is received by, any information is requested from, or any discussions or negotiations are sought to be initiated or continued with, MLP in respect of any Alternative Proposal, and shall, in any such notice to Parent, indicate the identity of the Person making such proposal, offer, inquiry or other contact and the terms and conditions of any proposals or offers or the nature of any inquiries or contacts (and shall include with such notice copies of any written materials received from or on behalf of such Person relating to such proposal, offer, inquiry or request), and thereafter shall promptly keep Parent reasonably informed of all material developments affecting the status and terms of any such proposals, offers, inquiries or requests (and MLP shall promptly provide Parent with copies of any additional written materials received by MLP or that MLP has delivered to any third party making an Alternative Proposal that relate to such proposals, offers, inquiries or requests) and of the status of any such discussions or negotiations.

(d) Notwithstanding any other provision of this Agreement, at any time prior to obtaining the MLP Unitholder Approval, the MLP GP Board may effect an Adverse Recommendation Change in response to an Alternative Proposal or a Changed Circumstance if the MLP GP Board, after consultation with its outside legal counsel and financial advisors, determines in good faith that the failure to take such action would be inconsistent with its duties under the MLP Partnership Agreement or applicable Law and:

(i) if the MLP GP Board intends to effect such Adverse Recommendation Change in response to an Alternative Proposal:

(A) such Alternative Proposal is bona fide, in writing and has not been withdrawn or abandoned;

(B) the MLP GP Board has determined, after consultation with its outside legal counsel and financial advisors, that such Alternative Proposal constitutes a Superior Proposal after giving effect to all of the adjustments offered by Parent pursuant to clause (E) below;

(C) MLP has provided prior written notice to Parent in accordance with Section 8.9 (the “Superior Proposal Notice”) of the MLP GP Board’s intention to effect an Adverse Recommendation Change, and such Superior Proposal Notice has specified the identity of the Person making such Alternative Proposal, the material terms and conditions of such Alternative Proposal, and complete copies of any written proposal or offers (including proposed agreements) received by MLP in connection with such Alternative Proposal;

(D) during the period that commences on the date of delivery of the Superior Proposal Notice as determined in accordance with Section 8.9 and ends at 11:59 p.m. Central time on the date that is the fifth calendar day following the date of such delivery (the “Superior Proposal Notice Period”), MLP shall (1) negotiate with Parent in good faith to

make such adjustments to the terms and conditions of this Agreement as would permit the MLP GP Board not to effect an Adverse Recommendation Change; and (2) keep Parent reasonably informed with respect to the status and changes in the material terms and conditions of such Alternative Proposal or other change in circumstances related thereto; provided, however, any material revisions to such Alternative Proposal (it being agreed that any change in the purchase price in such Alternative Proposal shall be deemed a material revision) shall require delivery of a subsequent Superior Proposal Notice and a subsequent Superior Proposal Notice Period in respect of such revised Alternative Proposal, except that such subsequent Superior Proposal Notice Period shall expire upon the later of (x) the end of the initial Superior Proposal Notice Period and (y) 11:59 p.m. Central time on the date that is the third calendar day following the date of the delivery of such subsequent Superior Proposal Notice; and

(E) the MLP GP Board shall have considered all revisions to the terms of this Agreement irrevocably offered in writing by Parent and, at the end of the Superior Proposal Notice Period, shall have determined in good faith that such Alternative Proposal continues to constitute a Superior Proposal even if such revisions were to be given effect; or

(ii) if the MLP GP Board intends to effect such Adverse Recommendation Change in response to a Changed Circumstance:

(A) MLP has provided prior written notice to Parent in accordance with Section 8.9 (the “Recommendation Change Notice”) of the MLP GP Board’s intention to effect an Adverse Recommendation Change, and such Recommendation Change Notice has specified the details of such Changed Circumstance and the reasons for the Adverse Recommendation Change;

(B) during the period that commences on the date of delivery of the Recommendation Change Notice as determined in accordance with Section 8.9 and ends at 11:59 p.m. Central time the date that is the fifth calendar day following the date of such delivery (the “Recommendation Change Notice Period”), MLP shall (i) negotiate with Parent in good faith to make such adjustments to the terms and conditions of this Agreement as would permit the MLP GP Board not to effect an Adverse Recommendation Change; and (ii) keep Parent reasonably informed of any change in circumstances related thereto; and

(C) the MLP GP Board shall have considered all revisions to the terms of this Agreement irrevocably offered in writing by Parent and, at the end of the Adverse Recommendation Change Notice Period, shall have determined in good faith that the failure to effect an Adverse Recommendation Change would be inconsistent with its duties under the MLP Partnership Agreement or applicable Law even if such revisions were to be given effect.

(e) Nothing contained in this Agreement shall prevent MLP or the MLP GP Board from issuing a “stop, look and listen” communication pursuant to Rule 14d-9(f) under the

Exchange Act or complying with Rule 14d-9 and Rule 14e-2 under the Exchange Act with respect to an Alternative Proposal if the MLP GP Board determines in good faith (after consultation with outside legal counsel) that its failure to do so would be reasonably likely to constitute a violation of applicable Law; provided that any Adverse Recommendation Change may only be made in accordance with Section 5.3(d). For the avoidance of doubt, a public statement that describes MLP’s receipt of an Alternative Proposal and the operation of this Agreement with respect thereto shall not be deemed an Adverse Recommendation Change.

Section 5.4 Reasonable Best Efforts.

(a) Subject to the terms and conditions of this Agreement (including Section 5.4(d)), each of the Parent Entities, on the one hand, and the MLP Entities, on the other hand, shall cooperate with the other and use (and shall cause their respective Subsidiaries to use) its reasonable best efforts to (i) take, or cause to be taken, all actions, and do, or cause to be done, all things, necessary, proper or advisable to cause the conditions to the Closing to be satisfied as promptly as practicable (and in any event no later than the Outside Date) and to consummate and make effective, in the most expeditious manner practicable, the transactions contemplated hereby, including preparing and filing promptly and fully all documentation to effect all necessary filings, notifications, notices, petitions, statements, registrations, submissions of information, applications and other documents (including any required or recommended filings under applicable Antitrust Laws, (ii) obtain promptly (and in any event no later than the Outside Date) all approvals, consents, clearances, expirations or terminations of waiting periods, registrations, permits, authorizations and other confirmations from any Governmental Authority or third party necessary, proper or advisable to consummate the transactions contemplated hereby, (iii) defend any lawsuits or other legal proceedings, whether judicial or administrative, challenging this Agreement or the consummation of the transactions contemplated hereby and (iv) obtain all necessary consents, approvals or waivers from third parties.

(b) In furtherance and not in limitation of the foregoing, (i) each party hereto (including by their respective Subsidiaries) agrees to make an appropriate filing of a Notification and Report Form pursuant to the HSR Act with respect to the transactions contemplated hereby as promptly as practicable and in any event within 15 business days after the date of this Agreement (unless a later date is mutually agreed to by the parties hereto) and to supply as promptly as practicable any additional information and documentary material that may be requested by any Governmental Authority pursuant to the HSR Act or any other Antitrust Law and use its reasonable best efforts to take, or cause to be taken (including by their respective Subsidiaries), all other actions consistent with this Section 5.4 necessary to cause the expiration or termination of the applicable waiting periods under the HSR Act as soon as practicable (and in any event no later than the Outside Date); and (ii) MLP and Parent shall each use its reasonable best efforts to (x) take all action necessary to ensure that no state takeover statute or similar Law is or becomes applicable to any of the transactions contemplated hereby and (y) if any state takeover statute or similar Law becomes applicable to any of the transactions contemplated hereby, take all action necessary to ensure that such transaction may be consummated as promptly as practicable on the terms contemplated by this Agreement and otherwise minimize the effect of such Law on the transaction.

(c) Each of the parties hereto shall use (and shall cause their respective Subsidiaries to use) its reasonable best efforts to (i) cooperate in all respects with each other in connection with any filing or submission with a Governmental Authority in connection with the transactions contemplated hereby and in connection with any investigation or other inquiry by or before a Governmental Authority relating to the transactions contemplated hereby, including any proceeding initiated by a private Person, (ii) promptly inform the other party of (and supply to the other party) any communication received by such party from, or given by such party to, the Federal Trade Commission, the Antitrust Division of the Department of Justice, or any other Governmental Authority and any material communication received or given in connection with any proceeding by a private Person, in each case regarding any of the transactions contemplated hereby, (iii) permit the other party to review in advance and incorporate the other party’s reasonable comments in any communication to be given by it to any Governmental Authority with respect to obtaining any clearances required under any Antitrust Law in connection with the transactions contemplated hereby and (iv) consult with the other party in advance of any meeting or teleconference with any Governmental Authority or, in connection with any proceeding by a private Person, with any other Person, and, to the extent not prohibited by the Governmental Authority or other Person, give the other party the opportunity to attend and participate in such meetings and teleconferences. Parent shall have the principal responsibility for devising and implementing the strategy for obtaining any clearances required under any Antitrust Law in connection with the transactions contemplated hereby and shall take the lead in all meetings and communications with any Governmental Authority in connection with obtaining such clearances, provided, however, that Parent shall consult in advance with MLP and in good faith take MLP’s views into account regarding the overall strategy. Subject to Section 5.6(b), the parties shall take reasonable efforts to share information protected from disclosure under the attorney-client privilege, work product doctrine, joint defense privilege or any other privilege pursuant to this Section 5.4 in a manner so as to preserve the applicable privilege.

(d) Parent and MLP (including by causing their respective Subsidiaries) agree to use their reasonable best efforts to (x) resolve any objections that a Governmental Authority or other Person may assert under any Antitrust Law with respect to the transactions contemplated hereby, and (y) avoid or eliminate each and every impediment under any Antitrust Law that may be asserted by any Governmental Authority with respect to the transactions contemplated hereby, in each case, so as to enable the Closing to occur as promptly as practicable and in any event no later than the Outside Date, and including taking or agreeing to take the types of actions, but subject to the limitations, described in the following sentence. Notwithstanding the foregoing or any other provision of this Agreement, MLP shall not, without Parent’s prior written consent, commit to any divestiture transaction or agree to any restriction on its business, and nothing in this Section 5.4 shall (i) limit any applicable rights a party may have to terminate this Agreement pursuant to Section 7.1 in a case where Section 7.1 permits such termination or (ii) require Parent to offer, accept or agree to (A) dispose or hold separate any part of MLP’s, Parent’s or their respective Subsidiaries’ businesses, operations or assets (or a combination thereof), (B) not compete in any geographic area or line of business, and/or (C) restrict the manner in which, or whether, Parent, MLP or any of their Subsidiaries may carry on business in any part of the world; provided, however, that Parent shall be required to offer, accept or agree to the actions in clauses (A), (B) and/or (C) if (and only if) the following conditions are satisfied: (1) any such dispositions or holdings separate of, and/or limitations or restrictions on, are, individually and in the aggregate, immaterial to the businesses, operations and/or assets of MLP, Parent or their

respective Subsidiaries (provided that, in the case of Parent and its Subsidiaries, for purposes of determining whether a business, operation or asset is immaterial, it shall be assumed that Parent and its Subsidiaries are of equivalent size to the current size of MLP and its Subsidiaries, in each case taken as a whole) and (2) the effect of any such dispositions, holdings separate, limitations and/or restrictions would not, individually or in the aggregate, reasonably be expected to result in a loss (other than an immaterial loss) of the reasonably expected benefits to Parent of the transactions contemplated hereby.

Section 5.5 Public Announcements. The initial press release with respect to the execution of this Agreement shall be a joint press release to be reasonably agreed upon by Parent and MLP. Thereafter, neither MLP nor Parent shall issue or cause the publication of any press release or other public announcement (to the extent previously issued or made in accordance with this Agreement) with respect to this Agreement or the transactions contemplated hereby without the prior consent of the other party (which consent shall not be unreasonably withheld or delayed), except as may be required by Law or by any applicable listing agreement with the NYSE or other national securities exchange as determined in the good faith judgment of the party proposing to make such release (in which case such party shall not issue or cause the publication of such press release or other public announcement without prior consultation with the other party); provided, however, that MLP shall not be required by this Section 5.5 to consult with any other party with respect to a public announcement in connection with the receipt and existence of an Alternative Proposal that the MLP GP Board believes is bona fide and matters related thereto or an Adverse Recommendation Change but nothing in this proviso shall limit any obligation of MLP under Section 5.3(d) to negotiate with Parent in good faith; provided, further, that each party and their respective controlled affiliates may make statements that are consistent with statements made in previous press releases, public disclosures or public statements made by Parent or MLP in compliance with this Section 5.5.

Section 5.6 Access to Information; Confidentiality.

(a) Upon reasonable notice and subject to applicable Laws relating to the exchange of information, each party shall, and shall cause each of its Subsidiaries to afford to the other party and its Representatives reasonable access during normal business hours (and, with respect to books and records, the right to copy) to all of its and its Subsidiaries’ properties, commitments, books, Contracts, records and correspondence (in each case, whether in physical or electronic form), officers, employees, accountants, counsel, financial advisors and other Representatives. Each party shall furnish promptly to the other party (i) a copy of each report, schedule and other document filed or submitted by it pursuant to the requirements of federal or state securities Laws and a copy of any communication (including “comment letters”) received by such party from the SEC concerning compliance with securities Laws and (ii) all other information concerning its and its Subsidiaries’ business, properties and personnel as the other party may reasonably request (including information necessary to prepare the Proxy Statement). Except for disclosures permitted by the terms of the Confidentiality Agreement, dated as of August 28, 2013, between Parent and MLP (as it may be amended from time to time, the “Parent

Confidentiality Agreement”), each party and its Representatives shall hold information received from the other party pursuant to this Section 5.6 in confidence in accordance with the terms of the Parent Confidentiality Agreement.

(b) This Section 5.6 shall not require either party to permit any access, or to disclose any information, that in the reasonable, good faith judgment (after consultation with counsel, which may be in-house counsel) of such party would reasonably be expected to result in (i) any violation of any contract or Law to which such party or its Subsidiaries is a party or is subject or cause any privilege (including attorney-client privilege) that such party or any of its Subsidiaries would be entitled to assert to be undermined with respect to such information and such undermining of such privilege could in such party’s good faith judgment (after consultation with counsel, which may be in-house counsel) adversely affect in any material respect such party’s position in any pending or, what such party believes in good faith (after consultation with counsel, which may be in-house counsel) could be, future litigation or (ii) if such party or any of its Subsidiaries, on the one hand, and the other party or any of its Subsidiaries, on the other hand, are adverse parties in a litigation, such information being reasonably pertinent thereto; provided that, in the case of clause (i), the parties hereto shall cooperate in seeking to find a way to allow disclosure of such information (including by entering into a joint-defense or similar agreement) to the extent doing so (1) would not (in the good faith belief of the party being requested to disclose the information (after consultation with counsel, which may be in-house counsel)) reasonably be likely to result in the violation of any such contract or Law or reasonably be likely to cause such privilege to be undermined with respect to such information or (2) could reasonably (in the good faith belief of the party being requested to disclose the information (after consultation with counsel, which may be in-house counsel)) be managed through the use of customary “clean-room” arrangements pursuant to which appropriately designated Representatives of the other party shall be provided access to such information; provided, further, that the party being requested to disclose the information shall (x) notify the other party that such disclosures are reasonably likely to violate its or its Subsidiaries’ obligations under any such contract or Law or are reasonably likely to cause such privilege to be undermined, (y) communicate to the other party in reasonable detail the facts giving rise to such notification and the subject matter of such information (to the extent it is able to do so in accordance with the first proviso in this Section 5.6(b)) and (z) in the case where such disclosures are reasonably likely to violate its or its Subsidiaries’ obligations under any contract, use reasonable commercial efforts to seek consent from the applicable third party to any such contract with respect to the disclosures prohibited thereby (to the extent not otherwise expressly prohibited by the terms of such contract).

(c) No investigation, or information received, pursuant to this Section 5.6 will modify any of the representations and warranties of the parties hereto.

Section 5.7 Notification of Certain Matters. MLP shall give prompt notice to Parent, and Parent shall give prompt notice to MLP, of (i) any notice or other communication received by such party from any Governmental Authority in connection with the transactions contemplated hereby or from any Person alleging that the consent of such Person is or may be required in connection with the transactions contemplated hereby, if the subject matter of such communication or the failure of such party to obtain such

consent is reasonably likely to be material to MLP or Parent, (ii) any actions, suits, claims, investigations or proceedings commenced or, to such party’s knowledge, threatened against, relating to or involving or otherwise affecting such party or any of its Subsidiaries and that relate to the transactions contemplated hereby, (iii) the discovery of any fact or circumstance that, or the occurrence or non-occurrence of any event the occurrence or non-occurrence of which, would result in the failure to be satisfied of any of the conditions to the Closing in Article VI and (iv) any material failure of such party to comply with or satisfy any covenant or agreement to be complied with or satisfied by it hereby which would result in the failure to be satisfied of any of the conditions to the Closing in Article VI; provided that, in the case of clauses (iii) and (iv), the failure to comply with this Section 5.7 shall not result in the failure to be satisfied of any of the conditions to the Closing in Article VI, or give rise to any right to terminate this Agreement under Article VII, if the underlying fact, circumstance, event or failure would not in and of itself give rise to such failure or right.

Section 5.8 Indemnification and Insurance.

(a) For purposes of this Section 5.8, (i) “Indemnified Person” shall mean any person who is now, or has been or becomes at any time prior to the Effective Time, an officer or director of MLP or any of its Subsidiaries and also with respect to any such Person, in their capacity as a director, officer, employee, member, trustee or fiduciary of another corporation, foundation, partnership, joint venture, trust, pension or other employee benefit plan or enterprise (whether or not such other entity or enterprise is affiliated with MLP) serving at the request of or on behalf of MLP or any of its Subsidiaries and together with such Person’s heirs, executors or administrators and (ii) “Proceeding” shall mean any actual or threatened claim, action, suit, proceeding or investigation, whether civil, criminal, administrative, investigative or otherwise and whether or not such claim, action, suit, proceeding or investigation results in a formal civil or criminal litigation or regulatory action.

(b) From and after the Effective Time, solely to the extent that MLP or any applicable Subsidiary would be permitted to indemnify an Indemnified Person, Parent and the Surviving Entity jointly and severally agree to (i) indemnify and hold harmless against any cost or expenses (including attorneys’ fees), judgments, fines, losses, claims, damages or liabilities and amounts paid in settlement in connection with any Proceeding, and provide advancement of expenses to, all Indemnified Persons to the fullest extent permitted under applicable Law and (ii) honor the provisions regarding elimination of liability of directors, indemnification of officers, directors and employees and advancement of expenses contained in the MLP Charter Documents and comparable governing instruments of any Subsidiary of MLP immediately prior to the Effective Time and ensure that the organizational documents of the Surviving Entity shall, for a period of six years following the Effective Time, contain provisions no less favorable with respect to indemnification, advancement of expenses and exculpation of present and former directors, officers and agents of MLP and its Subsidiaries than are presently set forth in the MLP Charter Documents. Any right of indemnification of an Indemnified Person pursuant to this Section 5.8(b) shall not be amended, repealed or otherwise modified at any time in a manner that would adversely affect the rights of such Indemnified Person as provided herein.

If the Effective Time does not occur until calendar year 2014, no new awards in respect of calendar year 2014 shall be made pursuant to MLP GP’s Annual Incentive Plan without the consent of Parent.

(e) Parent shall honor, or shall cause to be honored, all vacation that is accrued and unused by each of the MLP Employees as of the Effective Time and reflected on the balance sheet of MLP and its Subsidiaries (the “Pre-Closing Vacation”) in accordance with the terms of MLP’s policies as in effect as of immediately prior to the Effective Time, for the avoidance of doubt, including the terms of such policies regarding the forfeiture and carryover of such Pre-Closing Vacation. All vacation and paid time off that is accrued by each MLP Employee following the Effective Time shall be subject to the policies of Parent Managing GP.

(a) This Agreement shall be governed by, and construed in accordance with, the laws of the State of Delaware, applicable to contracts executed in and to be performed entirely within that State.

(b) Each of the parties hereto irrevocably agrees that any legal action or proceeding with respect to this Agreement and the rights and obligations arising hereunder, or for recognition and enforcement of any judgment in respect of this Agreement and the rights and obligations arising hereunder brought by the other party hereto or its successors or assigns, shall be brought and determined exclusively in the Delaware Court of Chancery and any state appellate court therefrom within the State of Delaware (or, if the Delaware Court of Chancery declines to accept jurisdiction over a particular matter, any state or federal court within the State of Delaware). Each of the parties hereto hereby irrevocably submits with regard to any such action or proceeding for itself and in respect of its property, generally and unconditionally, to the personal jurisdiction of the aforesaid courts and agrees that it will not bring any action relating to this Agreement or any of the transactions contemplated by this Agreement in any court other than the aforesaid courts. Each of the parties hereto hereby irrevocably waives, and agrees not to assert as a defense, counterclaim or otherwise, in any action or proceeding with respect to this Agreement, (i) any claim that it is not personally subject to the jurisdiction of the above named courts for any reason other than the failure to serve in accordance with this Section 8.7, (ii) any claim that it or its property is exempt or immune from the jurisdiction of any such court or from any legal process commenced in such courts (whether through service of notice, attachment prior to judgment, attachment in aid of execution of judgment, execution of judgment or otherwise) and (iii) to the fullest extent permitted by the applicable Law, any claim that (x) the suit, action or proceeding in such court is brought in an inconvenient forum, (y) the venue of such suit, action or proceeding is improper or (z) this Agreement, or the subject matter hereof, may not be enforced in or by such courts.

(c) EACH PARTY HEREBY IRREVOCABLY WAIVES ALL RIGHT TO TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM (WHETHER BASED ON CONTRACT, TORT OR OTHERWISE) ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY OR THE ACTIONS OF ANY PARTY IN THE NEGOTIATION, ADMINISTRATION, PERFORMANCE AND ENFORCEMENT OF THIS AGREEMENT AND THE TRANSACTIONS CONTEMPLATED BY THIS AGREEMENT.

Section 8.8 Specific Enforcement. The parties agree that irreparable damage would occur and that the parties would not have any adequate remedy at law in the event that any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached and it is accordingly agreed that the parties shall be entitled to an injunction or injunctions to prevent breaches of this Agreement and to enforce specifically the terms and provisions of this Agreement, in each case, in accordance with this Section 8.8 in the Delaware Court of Chancery or any federal court sitting in the State of Delaware, this being in addition to any other remedy to which they are entitled at law or in equity. Each of the parties agrees that it will not oppose the granting of an injunction, specific performance and other equitable relief as provided herein on the basis that (x) either party has an adequate remedy at law or (y) an award of specific performance is not an appropriate remedy for any reason at law or equity. Each party further agrees that no party shall be required to obtain, furnish or post any bond or similar instrument in connection with or as a condition to obtaining any remedy referred to in this Section 8.8, and each party irrevocably waives any right it may have to require the obtaining, furnishing or posting of any such bond or similar instrument. The parties agree that in the event that Parent receives the Termination Fee, Parent may not seek any award of specific performance under this Section 8.8
