ARTICLE III

MERGER CONSIDERATION; EXCHANGE PROCEDURES

Section 3.1 Merger Consideration. Subject to the provisions of this Agreement, at the Effective Time, by virtue of the Merger and without any action on the part of Parent, Merger Sub, the Partnership, the Partnership GP or any holder of Parent securities or Partnership securities:

(a) Conversion of Common Units. Subject to Section 3.1(c), Section 3.2(h) and Section 3.3, each Common Unit issued and outstanding as of immediately prior to the Effective Time shall be converted into the right to receive 0.985 of a Parent Share (the “Merger Consideration” and such ratio, the “Exchange Ratio”), which such Parent Shares will be duly authorized, validly issued, fully paid and non-assessable in accordance with applicable Laws, subject to adjustment in accordance with Section 3.3.

(b) Equity of Merger Sub. The limited liability company interests in Merger Sub issued and outstanding immediately prior to the Effective Time shall be converted into a number of Common Units of the Surviving Entity equal to the number of Common Units converted into the right to receive the Merger Consideration pursuant to Section 3.1(a), and Parent (which will be the sole member of Merger Sub or another designated Affiliate of Parent) shall be admitted as, or continue as, a limited partner of the Partnership (as the Surviving Entity). At the Effective Time, the books and records of the Partnership shall be revised to reflect the conversion of all Common Units held by Persons other than the Partnership GP, Parent and any Subsidiaries of Parent, and the Partnership (as the Surviving Entity) shall continue without dissolution.

(i) Notwithstanding anything to the contrary in this Agreement, at the Effective Time, all Common Units that are owned immediately prior to the Effective Time by the Partnership shall be automatically canceled and shall cease to exist and no consideration shall be delivered in exchange for such canceled Common Units.

(ii) All Partnership Interests, including any (i) General Partner Percentage Interests (which includes the Incentive Distribution Rights), (ii) Class B Units, (iii) Common Units, (iv) all Common Units that are owned by Subsidiaries of the Partnership, and (v) other Limited Partner Interests (as defined in the Partnership Agreement), that are owned immediately prior to the Effective Time by the Partnership GP, Parent or any Subsidiaries of Parent and not cancelled pursuant to Section 3.1(c)(i) shall, in each case, remain outstanding as partnership interests in the Surviving Entity, unaffected by the Merger.

(d) Certificates. As of the Effective Time, all Common Units converted into the right to receive the Merger Consideration pursuant to Section 3.1(a) shall no longer be outstanding and shall automatically be canceled and shall cease to exist, and each holder of a certificate that immediately prior to the Effective Time represented any such Common Units (a “Certificate”) or non-certificated Common Units represented in book-entry form immediately prior to the Effective Time (“Book-Entry Units”) shall cease to have any rights with respect thereto, except the right to receive the Merger Consideration, any dividends or other distributions to which such holder is entitled pursuant to Section 3.2(g) and cash in lieu of any fractional shares to which such holder is entitled pursuant to Section 3.2(h), in each case to be issued or paid in consideration therefor upon surrender of such Certificate or Book-Entry Unit in accordance with Section 3.2(c), without interest.

Section 3.2 Exchange of Certificates.

(a) Exchange Agent. Prior to the Closing Date, Parent shall appoint an exchange agent reasonably acceptable to the Partnership (the “Exchange Agent”) for the purpose of exchanging Certificates and Book-Entry Units for the Merger Consideration and paying any dividends or other distributions to which a holder of Common Units is entitled pursuant to Section 3.2(g) and any cash in lieu of any fractional shares to which such holder is entitled

pursuant to Section 3.2(h). As promptly as practicable after the Effective Time, Parent will send, or will cause the Exchange Agent to send, to each holder of record of Common Units as of the Effective Time whose Common Units were converted into the right to receive the Merger Consideration, a letter of transmittal (which shall specify that, with respect to certificated Common Units, the delivery shall be effected, and risk of loss and title shall pass, only upon proper delivery of the Certificates (or affidavits of loss in lieu thereof pursuant to Section 3.2(i)) to the Exchange Agent) in such customary forms as the Partnership 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 pursuant to Section 3.2(i)) and Book-Entry Units to the Exchange Agent in exchange for the Merger Consideration, cash in lieu of any fractional shares payable pursuant to Section 3.2(h) and any dividends or distributions pursuant to Section 3.2(g).

(b) Deposit. On or prior to the Closing Date, Parent shall cause to be deposited with the Exchange Agent, in trust for the benefit of the holders of Common Units whose Common Units are converting into the right to receive the Merger Consideration at the Effective Time, Parent Shares (which shares shall be uncertificated and registered in book-entry form), payable upon due surrender of the Certificates (or affidavits of loss in lieu thereof pursuant to Section 3.2(i) with respect to certificated Common Units) or Book-Entry Units pursuant to the provisions of this Article III. Following the Effective Time, Parent agrees to make available to the Exchange Agent, from time to time as needed, cash or other consideration as applicable sufficient to pay any dividends and other distributions pursuant to Section 3.2(g) and any Parent Shares or cash in lieu of any fractional shares payable pursuant to Section 3.2(h), in each case, that may be payable from time to time following the Effective Time. All Parent Shares and cash or other consideration payable in respect of any dividends or distributions pursuant to Section 3.2(g) deposited with the Exchange Agent or cash in lieu of any fractional shares as such holders have the right to receive pursuant to Section 3.2(h) shall be referred to in this Agreement as the “Exchange Fund.” The Exchange Agent shall, pursuant to irrevocable instructions delivered by Parent at or prior to the Effective Time, deliver the Merger Consideration contemplated to be issued or paid pursuant to this Article III out of the Exchange Fund. The Exchange Fund shall not be used for any purpose other than to pay such Merger Consideration, cash in lieu of any fractional shares payable pursuant to Section 3.2(h) and any dividends and other distributions pursuant to Section 3.2(g).

(c) Exchange. Each holder of Common Units that have been converted into the right to receive the Merger Consideration, upon delivery to the Exchange Agent of a properly completed letter of transmittal, duly executed and completed in accordance with the instructions thereto, and surrender of a Certificate (or affidavit of loss in lieu thereof pursuant to Section 3.2(i) with respect to certificated Common Units) or Book-Entry Units and such other documents as may reasonably be required by the Exchange Agent (including with respect to Book-Entry Units), will be entitled to receive in exchange therefor (i) the number of Parent Shares representing, in the aggregate, the whole number of Parent Shares that such holder has the right to receive in accordance with the provisions of this Article III, and (ii) a check in the amount of (A) the cash in lieu of any fractional shares payable pursuant to Section 3.2(h) and (B) such dividends or other distributions as such holder has the right to receive pursuant to Section 3.2(g). Any and all Parent Shares delivered in accordance with this Section 3.2(c) shall be uncertificated and shall be registered in book-entry form. The Merger Consideration and such other amounts as

reflected in the immediately preceding sentence shall be paid as promptly as practicable by mail after receipt by the Exchange Agent of the Certificate (or affidavit of loss in lieu thereof pursuant to Section 3.2(i) with respect to certificated Common Units) or any applicable documentation with respect to the surrender of Book-Entry Units, 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 shares or on any unpaid dividends and distributions payable to holders of Certificates and Book-Entry Units. Until so surrendered, each such Certificate and Book-Entry Unit shall, after the Effective Time, represent for all purposes only the right to receive such Merger Consideration and such other amounts as contemplated by Section 3.2(g) and Section 3.2(h).

(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 or Book-Entry Unit 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 Book-Entry Unit 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 or Book-Entry Unit 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 the Partnership of transfers of Common Units converted into the right to receive the Merger Consideration. From and after the Effective Time, the holders of Certificates or Book-Entry Units representing Common Units converted into the right to receive the Merger Consideration which were outstanding immediately prior to the Effective Time shall cease to have any rights with respect to such Common Units, except as otherwise provided in this Agreement or by applicable Law. If, after the Effective Time, Certificates or Book-Entry Units 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 III.

(f) Termination of Exchange Fund. Any portion of the Exchange Fund that remains unclaimed by the holders of Common Units converted into the right to receive the Merger Consideration nine (9) 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 for the Merger Consideration in accordance with this Section 3.2 prior to that time shall thereafter look only to Parent for delivery of the Merger Consideration, the payment of cash in lieu of any fractional shares payable pursuant to Section 3.2(h) and the payment of any dividends and other distributions pursuant to Section 3.2(g) in respect of such holder’s Common Units. Notwithstanding the foregoing, Parent, Merger Sub, the Partnership and the Partnership GP shall not be liable to any holder of Common Units for any Merger Consideration or other amount duly delivered to a public official pursuant to applicable abandoned property Laws. Any Merger

Consideration and other amounts remaining unclaimed by holders of Common 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) Dividends and Distributions. No dividends or other distributions with respect to Parent Shares issued in the Merger shall be paid to the holder of any unsurrendered Certificates or Book-Entry Units until such Certificates or Book-Entry Units are surrendered as provided in this Section 3.2. 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 Shares, if any, issued in exchange therefor (i) at the time of such surrender, all dividends and other distributions payable in respect of any such Parent Shares 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 dividends or other distributions payable with respect to such Parent Shares with a record date after the Effective Time but with a payment date subsequent to such surrender. For purposes of dividends or other distributions in respect of Parent Shares, all Parent Shares to be issued pursuant to the Merger shall be entitled to dividends pursuant to the immediately preceding sentence as if issued and outstanding as of the Effective Time.

(h) No Fractional Shares. No fractions of a Parent Share will be issued upon the surrender of Common Units outstanding immediately prior to the Effective Time in accordance with Section 3.2(c), and such fractional interests will not entitle the owner thereof to vote or to have any rights as a holder of any Parent Shares. Notwithstanding any other provision of this Agreement, each holder of Common Units converted into the right to receive the Merger Consideration in the Merger who would otherwise have been entitled to receive a fraction of a Parent Share (after taking into account all Common Units exchanged by such holder) will receive, in lieu thereof, cash (without interest and rounded up to the nearest whole cent) in an amount equal to the product of (i) the Average Closing Price as of the Closing Date and (ii) the fraction of a Parent Share that such holder would otherwise be entitled to receive pursuant to this Article III. As promptly as practicable after the determination of the amount of cash, if any, to be paid to holders of fractional interests, Parent will cause the Exchange Agent to forward payments to such holders of fractional interests subject to and in accordance with the terms of this Agreement. The parties acknowledge that payment of such cash consideration in lieu of issuing fractional Parent Shares 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 Parent Shares.

(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 III and pay cash in lieu of any fractional shares payable pursuant to Section 3.2(h) and any dividends and other distributions pursuant to Section 3.2(g).

(j) Withholding Taxes. Parent, Merger Sub, the Surviving Entity and the Exchange Agent shall deduct and withhold from the consideration otherwise payable pursuant to this Agreement such amounts, if any, 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, and the rules and regulations promulgated thereunder (the “Code”), 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 cash or Parent Common Stock, as determined by Parent). To the extent amounts are so withheld and paid over to the appropriate taxing 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 in respect of whom such withholding was made. If withholding is taken in Parent Shares, 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 taxing authority.

Section 3.3 Adjustments. Notwithstanding any provision of this Article III to the contrary, if between the date of this Agreement and the Effective Time the number of outstanding Common Units or Parent Shares shall have been changed into a different number of units or shares or a different class or series by reason of any unit or share dividend, subdivision, reclassification, recapitalization, split, split-up, unit or share distribution, combination, exchange of units or shares or similar transaction, the Merger Consideration and any other similar dependent item, as the case may be, shall be appropriately adjusted to reflect fully the effect of such unit or share dividend, subdivision, reclassification, recapitalization, split, split-up, unit or share distribution, combination, exchange of units or shares or similar transaction and to provide the holders of Common Units the same economic effect as contemplated by this Agreement prior to such event; provided, however, that nothing in this Section 3.3 shall be deemed to permit or authorize any party hereto to affect any such change that it is not otherwise authorized or permitted to undertake pursuant to this Agreement.

Section 3.4 No Dissenters’ Rights. No dissenters’ or appraisal rights shall be available with respect to the Merger or the other transactions contemplated by this Agreement.

Section 4.5 Partnership SEC Documents; Undisclosed Liabilities; Internal Controls.

(a) The Partnership and its Subsidiaries have filed or furnished all reports, schedules, forms, certifications, prospectuses, and registration, proxy and other statements required to be filed or furnished by them with the SEC since December 31, 2013 (collectively and together with all documents filed or publicly furnished on a voluntary basis on Form 8-K, and in each case including all exhibits and schedules thereto and documents incorporated by reference therein, the “Partnership SEC Documents”). The Partnership SEC Documents, as of their respective effective dates (in the case of Partnership SEC Documents that are registration statements filed pursuant to the requirements of the Securities Act) and as of their respective

SEC filing dates (in the case of all other Partnership SEC Documents), or, if amended, as finally amended prior to the date of this Agreement, complied in all material respects with the requirements of the Exchange Act, the Securities Act and the ▇▇▇▇▇▇▇▇-▇▇▇▇▇ Act of 2002 (the “▇▇▇▇▇▇▇▇-▇▇▇▇▇ Act”), as the case may be, applicable to such Partnership SEC Documents, and none of the Partnership SEC Documents as of such respective dates contained any untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading.

(b) The consolidated financial statements of the Partnership included in the Partnership SEC Documents as of their respective dates (if amended, as of the date of the last such amendment) comply as to form in all material respects with applicable accounting requirements and the published rules and regulations of the SEC with respect thereto, have been prepared in accordance with GAAP (except, in the case of unaudited quarterly statements, as indicated in the notes thereto) applied on a consistent basis during the periods involved (except as may be indicated in the notes thereto) and fairly present in all material respects the consolidated financial position of the Partnership and its consolidated Subsidiaries as of the dates thereof and the consolidated results of their operations and cash flows for the periods then ended (subject, in the case of unaudited quarterly statements, to normal year-end audit adjustments, none of which has been or will be, individually or in the aggregate, material to the Partnership and its consolidated Subsidiaries, taken as a whole).

(c) Except (i) as reflected or otherwise reserved against on the balance sheet of the Partnership and its consolidated Subsidiaries (including the notes thereto) included in the Partnership SEC Documents filed by the Partnership and publicly available prior to the date of this Agreement, (ii) for liabilities and obligations incurred since December 31, 2015 (the “Balance Sheet Date”) in the ordinary course of business consistent with past practice and (iii) for liabilities and obligations incurred under or in accordance with this Agreement or in connection with the transactions contemplated by this Agreement, neither the Partnership nor any of its Subsidiaries has any liabilities or obligations of any nature (whether or not accrued or contingent), that would be required to be reflected or reserved against on a consolidated balance sheet of the Partnership prepared in accordance with GAAP or the notes thereto, other than as have not and would not reasonably be expected to have, individually or in the aggregate, a Partnership Material Adverse Effect.

(d) No Partnership Subsidiary is required to file reports, forms or other documents with the SEC pursuant to the Exchange Act. There are no outstanding comments from, or unresolved issues raised by, the staff of the SEC with respect to the Partnership SEC Documents. No enforcement action has been initiated against the Partnership relating to disclosures contained or omitted from any Partnership SEC Document.

(e) The Partnership makes and keeps books, records, and accounts and has devised and maintains a system of internal controls, in each case, in all material respects, as required pursuant to Section 13(b)(2) under the Exchange Act. The Partnership has established and maintains disclosure controls and procedures and internal control over financial reporting (as such terms are defined in paragraphs (e) and (f), respectively, of Rule 13a-15 under the Exchange Act) as required by Rule 13a-15 under the Exchange Act and the applicable listing

standards of the NYSE.

Except as permitted by this Section 6.3, Parent shall not, and shall cause its respective Subsidiaries and the foregoing shall use their reasonable best efforts to cause their respective 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) enter into an Alternative Acquisition Agreement, or (iii) (A) withdraw, modify or qualify, or propose publicly to withdraw, modify or qualify, in a manner adverse to the Partnership, the Parent Special Committee Recommendation, (B) fail to include the Parent Special Committee Recommendation in the Joint Proxy Statement, (C) authorize, approve, declare advisable, adopt or recommend or propose to publicly authorize, approve, declare advisable, adopt or recommend, any Alternative Proposal or (D) authorize Parent or any of its Subsidiaries to enter into an Alternative Acquisition Agreement or enter into an agreement,

Without limiting the foregoing, it is understood that any violation of the foregoing restrictions by Parent’s Subsidiaries or Parent’s Representatives shall be deemed to be a breach of this Section 6.3 by Parent.

(e) Notwithstanding anything to the contrary contained in Section 6.3(d), if at any time following the date of this Agreement and prior to obtaining the Parent Stockholder Approval, (i) Parent has received a written Alternative Proposal that the Parent Board believes is bona fide, (ii) the Parent Board, after consultation with its financial advisors and outside legal counsel, determines in good faith that (x) such Alternative Proposal constitutes or could reasonably be expected to lead to or result in a Superior Proposal and (y) failure to take such action would be inconsistent with its duties under applicable Law and (iii) such Alternative Proposal did not result from a material breach of this Section 6.3, then Parent may, subject to clauses (x) and (y) below, (A) furnish information, including confidential information, with respect to Parent and its Subsidiaries to the Person making such Alternative Proposal and (B) participate in discussions or negotiations regarding such Alternative Proposal; provided, however, that (x) Parent and its respective Subsidiaries will not, and will use their reasonable best efforts to cause their respective Representatives not to, disclose any non-public information to such Person unless Parent has, or first enters into, an Acceptable Confidentiality Agreement with such Person and (y) Parent will provide to the Partnership and the Partnership GP non-public information with respect to Parent and its Subsidiaries that was not previously provided or made available to the Partnership or the Partnership GP prior to or substantially concurrently with providing or making available such non-public information to such other Person.

(f) Notwithstanding anything to the contrary in this Agreement, at any time prior to obtaining the Parent Stockholder Approval, and subject to compliance in all material respects with this Section 6.3(f), the Parent Board or Parent Special Committee, as the case may be, may (x) make a Parent Adverse Recommendation Change or (y) solely in the case of Section 6.3(f)(i)(A) terminate this Agreement pursuant to Section 8.1(c)(iii), in each case:

(i) (A) if Parent has received a written Alternative Proposal that the Parent Board or Parent Special Committee, as the case may be, believes is bona fide, and the Parent Board or Parent Special Committee, as the case may be, after consultation with its financial advisors and outside legal counsel, determines in good faith that (x) such Alternative Proposal constitutes a Superior Proposal and (y) failure to take such action would be inconsistent with its duties under applicable Law or (B) in response to an Intervening Event if the Parent Board or Parent Special Committee, as the case may be, after consultation with its financial advisors and outside legal counsel, determines in good faith that the failure to take such action would be inconsistent with its duties under applicable Law;

(ii) if the Parent Board or Parent Special Committee, as the case may be, has provided prior written notice to the Partnership (A) in the case of Section 6.3(f)(i)(A), (x) stating that the Parent Board or Parent Special Committee, as the case may be, after consultation with its financial advisors and outside legal counsel, has determined in good faith that such Alternative Proposal constitutes a Superior Proposal and (y) including a description of the material terms of such Alternative Proposal and (B) in the case of Section 6.3(f)(i)(B), specifying in reasonable detail the material events giving rise to the Intervening Event, in the case of each of (A) and (B), at least three (3) days in advance of

its intention to take such action with respect to a Parent Adverse Recommendation Change, unless at the time such notice is otherwise required to be given there are less than three (3) days prior to the Parent Stockholder Meeting, in which case the Parent Board or Parent Special Committee, as the case may be, shall provide as much notice as is practicable (it being understood and agreed that any material amendment to the terms of an Alternative Proposal, if applicable, shall require a new notice pursuant to this Section 6.3(f) and a new Parent Notice Period, except that such new Parent Notice Period in connection with any material amendment to the terms of an Alternative Proposal shall be for one (1) day from the time the Partnership receives such notice (as opposed to three (3) days) (the period inclusive of all such days, the “Parent Notice Period”); and

(iii) if, during the Parent Notice Period, the Parent Board or Parent Special Committee, as the case may be, has negotiated, and has used its reasonable best efforts to cause its financial advisors and outside legal counsel to negotiate, with the Partnership and the Partnership GP in good faith (to the extent the Partnership and the Partnership GP desire to negotiate) to make such adjustments in the terms and conditions of this Agreement so that the failure to effect such Parent Adverse Recommendation Change would not be inconsistent with its duties under applicable Law; provided, however, that the Parent Board or Parent Special Committee, as the case may be, shall take into account all changes to the terms of this Agreement proposed by the Partnership in determining whether (1) in the case of Section 6.3(f)(i)(A), such Alternative Proposal continues to constitute a Superior Proposal or (2) in the case of Section 6.3(f)(i)(B), the failure to effect such Parent Adverse Recommendation Change would not be inconsistent with its duties under applicable Law.

(g) For purposes of this Agreement:

(i) “Acceptable Confidentiality Agreement” means a confidentiality agreement containing customary provisions, including, for the avoidance of doubt, provisions limiting the use of the confidential information to be provided thereunder.

(ii) “Alternative Proposal” means any inquiry, proposal or offer from any Person or “group” (as defined in Section 13(d) of the Exchange Act), relating to any (1) direct or indirect acquisition (whether in a single transaction or a series of related transactions), outside of the ordinary course of business, of assets of Parent and its Subsidiaries (including securities of Subsidiaries) equal to twenty-five percent (25%) or more of Parent’s consolidated assets or to which twenty-five percent (25%) or more of Parent’s revenues or earnings on a consolidated basis are attributable, (2) direct or indirect acquisition (whether in a single transaction or a series of related transactions) of beneficial ownership (within the meaning of Section 13 under the Exchange Act) of twenty-five percent (25%) or more of any outstanding class of equity securities of Parent, (3) tender offer or exchange offer that if consummated would result in any Person or “group” (as defined in Section 13(d) of the Exchange Act) beneficially owning twenty-five percent (25%) or more of any outstanding class of equity securities of Parent or (4) merger, consolidation, unit exchange, share exchange, business combination, recapitalization, liquidation, dissolution or similar transaction involving Parent which is structured to permit such Person or group to acquire beneficial ownership of at least twenty-five percent (25%) of the Parent’s consolidated assets or outstanding equity

interests; in each case, other than the transactions contemplated by this Agreement. Notwithstanding the foregoing, an “Alternative Proposal” shall not include any inquiry, proposal or offer that would not reasonably be expected to prevent or materially impede, interfere with, hinder or delay the consummation of the transactions contemplated by this Agreement.

(iii) “Intervening Event” means a material event, fact or circumstance, development or occurrence that is not known or reasonably foreseeable to or by the GP Board, the GP Conflicts Committee or the Parent Board or Parent Special Committee, as the case may be, as of the date of this Agreement, which event, fact, circumstance, development or occurrence becomes known to or by (x) the GP Board or the GP Conflicts Committee, as the case may be, prior to the Partnership Unitholder Meeting or (y) the Parent Board or Parent Special Committee, as the case may be, prior to the Parent Stockholder Meeting.

(iv) “Superior Proposal” means a bona fide written offer, obtained after the date of this Agreement and not in material breach of this Section 6.3, to acquire, directly or indirectly, more than fifty percent (50%) of the outstanding equity securities of Parent or assets of Parent and its Subsidiaries on a consolidated basis, made by a third party, which is on terms and conditions which the Parent Board or Parent Special Committee, as the case may be, determines in its good faith to be more favorable to the Parent Stockholders from a financial point of view than the transactions contemplated by this Agreement, taking into account any changes to the terms of this Agreement that as of the time of determination had been committed to by the Partnership in writing.

(h) Nothing contained in this Agreement shall prevent the Partnership, the GP Board or the GP Conflicts Committee or shall prevent Parent, Parent Special Committee or the Parent Board, as applicable, 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 GP Conflicts Committee or the Parent Board or Parent Special Committee, as the case may be, as applicable, 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, however, that any Partnership Adverse Recommendation Change or Parent Adverse Recommendation Change may only be made in accordance with Section 6.3(b) or Section 6.3(f), as the case may be.

(c) Each of the parties hereto shall, and shall cause their respective Subsidiaries to, use its reasonable best efforts to (i) cooperate in all respects with each other party in connection with any filing or submission with a Governmental Authority in connection with the transactions contemplated hereby, including by providing the other party a reasonable opportunity to review and comment thereon, 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, and (ii) promptly inform the other party of (and supply to the other party) any written 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 written communication received or given in connection with any proceeding by a private Person, in each case regarding any of the transactions contemplated hereby.

Subject to applicable Laws, during such period, Parent shall furnish promptly to the Partnership (i) a copy of each report, schedule, registration statement and other document filed, published, announced or received by it in connection with the transactions contemplated by this Agreement during such period pursuant to the requirements of federal, state or foreign Laws (including pursuant to the Securities Act, the Exchange Act and the rules of any Governmental Authority thereunder), as applicable (other than documents which such party is not permitted to disclose under applicable Laws) and (ii) all information concerning Parent’s business, properties and personnel as the Partnership may reasonably request, including all information relating to environmental matters. Notwithstanding the foregoing, no party shall have an obligation to disclose or provide access to any information the disclosure of which the other party has concluded may jeopardize any privilege available to such party or any of its Affiliates relating to such information or would be in violation of a confidentiality obligation binding on such party or any of its Affiliates. Except for disclosures permitted by the terms of the Confidentiality Agreement, dated as of January 19, 2017 between Parent and the Partnership GP (as it may be amended from time to time, the “Confidentiality Agreement”), the each party shall hold information received from the other party pursuant to this Section 6.6 in confidence in accordance with the terms of the Confidentiality Agreement.

Section 6.7 Indemnification and Insurance.

(a) From and after the Effective Time, solely to the extent that the Partnership or the Partnership GP or any applicable Subsidiary thereof would be permitted to indemnify an Indemnified Person immediately prior to the Effective Time, Parent and the Surviving Entity jointly and severally agree to (i) indemnify and hold harmless against any reasonable costs or expenses (including reasonable attorneys’ fees and all other reasonable costs, expenses and obligations (including experts’ fees, travel expenses, court costs, retainers, transcript fees, duplicating, printing and binding costs, as well as telecommunications, postage and courier charges) paid or incurred in connection with investigating, defending, being a witness in or participating in (including on appeal), or preparing to investigate, defend, be a witness in or participate in, any Proceeding, including any Proceeding relating to a claim for indemnification or advancement brought by an Indemnified Person), judgments, fines, losses, claims, damages or liabilities, penalties and amounts paid in settlement (including all interest, assessments and other charges paid or payable in connection with or in respect of any thereof) in connection with any actual or threatened Proceeding, and, upon receipt by Parent of an undertaking by or on behalf of

the Indemnified Person to repay such amount if it shall be determined in a final and non-appealable judgment entered by a court of competent jurisdiction that the Indemnified Person is not entitled to be indemnified, provide advancement of expenses with respect to each of the foregoing to, all Indemnified Persons to the fullest extent permitted under applicable Law and (ii) honor the provisions regarding elimination of liability of officers and directors, indemnification of officers, directors and employees and advancement of expenses contained in the Organizational Documents of the Partnership and the Partnership GP immediately prior to the Effective Time, and ensure that the Organizational Documents of the Partnership and the Partnership GP or any of their respective successors or assigns, if applicable, 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 employees of the Partnership and the Partnership GP than are presently set forth in such Organizational Documents. Any right of an Indemnified Person pursuant to this Section 6.7(a) shall not be amended, repealed, terminated or otherwise modified at any time in a manner that would adversely affect the rights of such Indemnified Person as provided herein, and shall be enforceable by such Indemnified Person and their respective heirs and representatives against Parent and the Partnership GP and their respective successors and assigns.

(b) Parent shall maintain in effect for six (6) years from the Effective Time Parent’s current directors’ and officers’ liability insurance policies covering acts or omissions occurring at or prior to the Effective Time with respect to Indemnified Persons (provided that Parent may substitute therefor policies with reputable carriers of at least the same coverage containing terms and conditions that are no less favorable to the Indemnified Persons); provided, however, that in no event shall Parent be required to expend pursuant to this Section 6.7(b) more than an amount per year equal to 300% of current annual premiums paid by Parent for such insurance (the “Maximum Amount”). In the event that, but for the proviso to the immediately preceding sentence, Parent would be required to expend more than the Maximum Amount, Parent shall obtain the maximum amount of such insurance as is available for the Maximum Amount. If Parent in its sole discretion elects, then, in lieu of the obligations of Parent under this Section 6.7(b), Parent may (but shall be under no obligation to), prior to the Effective Time, purchase a “tail policy” with respect to acts or omissions occurring or alleged to have occurred prior to the Effective Time that were committed or alleged to have been committed by such Indemnified Persons in their capacity as such.

(c) The rights of any Indemnified Person under this Section 6.7 shall be in addition to any other rights such Indemnified Person may have under the Organizational Documents of the Partnership and the Partnership GP, any indemnification agreements, or the DLLCA and DRULPA. The provisions of this Section 6.7 shall survive the consummation of the transactions contemplated by this Agreement for a period of six (6) years and are expressly intended to benefit each of the Indemnified Persons and their respective heirs and representatives; provided, however, that in the event that any claim or claims for indemnification or advancement set forth in this Section 6.7 are asserted or made within such six (6)-year period, all rights to indemnification and advancement in respect of any such claim or claims shall continue until disposition of all such claims. If Parent and/or the Partnership GP, or any of their respective successors or assigns (i) consolidates with or merges into any other Person, or (ii) transfers or conveys all or substantially all of their businesses or assets to any other Person, then,

in each such case, to the extent necessary, a proper provision shall be made so that the successors and assigns of Parent and/or the Partnership GP shall assume the obligations of Parent and the Partnership GP set forth in this Section 6.7.

Section 6.8 Fees and Expenses. Except as otherwise provided in Section 8.2 and Section 8.3, all fees and expenses incurred in connection with the transactions contemplated by this Agreement including all legal, accounting, financial advisory, consulting and all other fees and expenses of third parties incurred by a party in connection with the negotiation and effectuation of the terms and conditions of this Agreement and the transactions contemplated by this Agreement, shall be the obligation of the respective party incurring such fees and expenses, except Parent and the Partnership shall each bear and pay one half of the expenses incurred in connection with the filing, printing and mailing of the Registration Statement and Joint Proxy Statement.

Section 6.9 Section 16 Matters. Prior to the Effective Time, Parent and the Partnership shall take all such steps as may be required (to the extent permitted under applicable Law) to cause any dispositions of Common Units (including derivative securities with respect to Common Units) or acquisitions of Parent Common Stock (including derivative securities with respect to Parent Common Stock) resulting from the transactions contemplated by this Agreement by each individual who is subject to the reporting requirements of Section 16(a) of the Exchange Act with respect to the Partnership, or will become subject to such reporting requirements with respect to Parent, to be exempt under Rule 16b-3 promulgated under the Exchange Act.

Section 6.10 Listing. Parent shall use reasonable best efforts to cause the Parent Common Stock to be issued pursuant to and in accordance with this Agreement to be approved for listing (subject, if applicable, to notice of issuance) for trading on the NYSE prior to the Closing.

After the date of this Agreement until the Effective Time, each of Parent and the Partnership shall coordinate with the other regarding the declaration of any dividends or distributions in respect of Parent Common Stock and Partnership Interests and the record dates and payment dates relating thereto, it being the intention of the parties that holders of Partnership Interests shall not receive, for any quarter, distributions both in respect of Partnership Interests and also dividends in respect of Parent Common Stock that they receive in exchange therefor in the Merger, but that they shall receive for any such quarter either: (a) only distributions in respect of Partnership Interests or (b) only dividends in respect of Parent Common Stock that they receive in exchange therefor in the Merger. Upon consummation of the transactions contemplated hereby, each of the parties hereto understands that, as of the date hereof, Parent management intends to recommend to Parent’s Board immediately following the Closing to increase the quarterly dividend on the shares of Parent Common Stock to no less than $0.745 per share prior to the first dividend declaration date immediately following the Closing.

Section 6.12 GP Conflicts Committee. Prior to the earlier of the Effective Time and the termination of this Agreement, Parent shall not and it shall not permit any of its Subsidiaries to, and it shall not and shall not permit any of its Subsidiaries to take any action

For the avoidance of doubt, this Section 6.12 shall not apply to the filling, in accordance with the provisions of the Partnership GP LLC Agreement, of any vacancies caused by the resignation, death or incapacity of any such director.

Section 6.13 Performance by Partnership GP. The Partnership GP shall cause the Partnership and its Subsidiaries to comply with the provisions of this Agreement. Notwithstanding the foregoing, it is understood and agreed that actions or inactions by the Partnership and the Partnership GP and their respective Subsidiaries shall not be deemed to be breaches or violations or failures to perform by Parent or its Subsidiaries of any of the provisions of this Agreement unless such action or inaction was or was not taken at the direction of or on the recommendation of, or with respect to the Partnership and the Partnership GP and their respective Subsidiaries and subject to Section 6.2(b), with the consent of, Parent.

Section 6.14 Cooperation with Debt and Equity Financing. From and after the date of this Agreement, the Partnership shall, and the Partnership shall cause each of its Subsidiaries and use reasonable best efforts to cause its and their representatives (including their auditors) to, use its respective reasonable best efforts to provide all customary cooperation (including providing reasonably available financial and other information regarding the Partnership and its Subsidiaries for use in marketing and offering documents and to enable Parent to prepare pro forma financial statements) as reasonably requested by Parent to assist Parent in the arrangement of any bank debt financing or any capital markets debt or equity financing, any repayment or refinancing of debt contemplated by this Agreement or required in connection with the transactions contemplated by this Agreement and any other amounts required to be paid in connection with the consummation of the Merger; it being understood that the arrangement of any bank debt financing or any capital markets debt financing or the repayment or refinancing of any debt shall not be a condition to Parent’s or Merger Sub’s obligations to effect the Merger. Parent shall indemnify and hold harmless the Partnership GP, the Partnership and their respective Subsidiaries from and against any and all losses or damages actually suffered or incurred by them directly in connection with the arrangement of any such bank debt financing or any capital markets debt financing.

Section 6.15 Tax Treatment. For United States federal income tax purposes (and for purposes of any applicable state, local or foreign Tax that follows the United States federal income tax treatment), the parties agree to treat the Merger (a) with respect to the holders of Common Units (other than Common Units held by Parent and its Subsidiaries immediately prior to the Effective Time) (the “Public Common Units”), as a taxable sale of the Public Common Units to Parent and (b) with respect to Parent, as a purchase of the Public Common Units from the holders of such Common Units. The parties will prepare and file all Tax Returns consistent with the foregoing and will not take any inconsistent position on any Tax Return, or during the course of any Proceeding with respect to Taxes, except as otherwise required by applicable Law following a final determination by a court of competent jurisdiction or other administrative settlement with or final administrative decision by the relevant Governmental Authority.

Section 6.16 Takeover Statutes. Parent shall not, and shall cause its Subsidiaries not to, take any action that would, or would reasonably be expected to, cause any Takeover Law to become applicable to this Agreement, the Merger, the Parent Stock Issuance or the other transactions contemplated hereby or related thereto. If any Takeover Law shall become applicable to this Agreement, the Merger, the Parent Stock Issuance or the other transactions contemplated hereby or related thereto, Parent, Parent Board and the Parent Special Committee shall grant such approvals and shall use reasonable best efforts to take such actions so that the transactions contemplated hereby, including the Merger and the Parent Stock Issuance, may be consummated as promptly as practicable on the terms contemplated hereby and otherwise use reasonable best efforts to eliminate or minimize the effects of such statute or regulation on the transactions contemplated hereby, including the Merger and the Parent Stock Issuance.

Section 6.17 Securityholder Litigation. The Partnership and Partnership GP shall give Parent the opportunity to participate in the defense or settlement of any securityholder litigation against the Partnership and the Partnership GP and/or their directors (as applicable) relating to the transactions contemplated by this Agreement, provided that the Partnership and the Partnership GP shall in any event control such defense and/or settlement and shall not be required to provide information if doing so would be reasonably expected to violate the confidentiality obligations of such party or threaten the loss of any attorney-client privilege or other applicable legal privilege.

(a) Neither the Partnership nor the Partnership GP may rely on the failure of any condition set forth in Section 7.1, Section 7.2 or Section 7.3, as the case may be, to be satisfied if such failure was due to the failure of either such party to perform and comply in all material respects with the covenants and agreements in this Agreement to be performed or complied with by it prior to the Closing.

(b) Neither Parent nor Merger Sub may rely on the failure of any condition set forth in Section 7.1, Section 7.2 or Section 7.3, as the case may be, to be satisfied if such failure was due to the failure of either such party to perform and comply in all material respects with the covenants and agreements in this Agreement to be performed or complied with by it prior to the Closing.

ARTICLE VIII

TERMINATION

Section 8.1 Termination. This Agreement may be terminated and the transactions contemplated by this Agreement abandoned at any time prior to the Effective Time:

(a) by the mutual written consent of the Partnership and Parent duly authorized by the Parent Board or Parent Special Committee, as the case may be, and the GP Conflicts Committee.

(b) by either of the Partnership or Parent:

(i) if the Closing shall not have been consummated on or before September 30, 2017 (the “Outside Date”); provided, however, that the right to terminate this Agreement under this Section 8.1(b)(i) shall not be available (A) to the Partnership or Parent if the failure to satisfy such condition was due to the failure of, in the case of the Partnership, the Partnership or the Partnership GP and, in the case of Parent, Parent or Merger Sub, to perform and comply in all material respects with the covenants and agreements to be performed or complied with by it prior to the Closing or (B) to the Partnership or Parent if, in the case of Parent, the Partnership or the Partnership GP and, in the case of the Partnership, Parent or Merger Sub, has filed (and is then pursuing) an action seeking specific performance as permitted by Section 9.9;

(ii) if any Restraint having the effect set forth in Section 7.1(d) shall be in effect and shall have become final and nonappealable; provided, however, that the right to terminate this Agreement under this Section 8.1(b)(ii) shall not be available to the Partnership or Parent if such Restraint was due to the failure of, in the case of the Partnership, the Partnership or the Partnership GP and, in the case of Parent, Parent or Merger Sub, to perform any of its obligations under this Agreement;

(iii) if the Partnership Unitholder Meeting and any postponements or adjournments thereof shall have concluded and the Partnership Unitholder Approval shall not have been obtained; or

(iv) if the Parent Stockholder Meeting and any postponements or adjournments thereof shall have concluded and the Parent Stockholder Approval shall not have been obtained.

(i) if a Partnership Adverse Recommendation Change shall have occurred prior to the Partnership Unitholder Meeting;

(ii) if the Partnership or the Partnership GP shall have breached or failed to perform any of its representations, warranties, covenants or agreements set forth in this Agreement (or if any of the representations or warranties of the Partnership or the Partnership GP set forth in this Agreement shall fail to be true), which breach or failure (A) would (if it occurred or was continuing as of the Closing Date) give rise to the failure of a condition set forth in Section 7.2(a) or Section 7.2(b) and (B) is incapable of being cured, or is not cured, by the Partnership or the Partnership GP within thirty (30) days following receipt of written notice from Parent of such breach or failure; provided, however, that Parent shall not have the right to terminate this Agreement pursuant to this Section 8.1(c)(ii) if Parent or Merger Sub is then in material breach of any of its representations, warranties, covenants or agreements contained in this Agreement; or

(iii) prior to the receipt of the Parent Stockholder Approval, in order to enter into an Alternative Acquisition Agreement with respect to a Superior Proposal; provided that Parent shall have complied in all material respects with Section 6.3(f), and shall concurrently make the amendment contemplated by Section 8.3(m) with respect to, the Break-Up Amount in accordance with Section 8.3(f).

(d) by the Partnership:

(i) if a Parent Adverse Recommendation Change shall have occurred prior to the Parent Stockholder Meeting;

(ii) if Parent shall have breached or failed to perform any of its representations, warranties, covenants or agreements set forth in this Agreement (or if any of the representations or warranties of Parent set forth in this Agreement shall fail to be true), which breach or failure (A) would (if it occurred or was continuing as of the Closing Date) give rise to the failure of a condition set forth in Section 7.3(a) or Section 7.3(b) and (B) is incapable of being cured, or is not cured, by Parent within thirty (30) days following receipt of written notice from the Partnership of such breach or failure; provided, however, that the Partnership shall not have the right to terminate this Agreement pursuant to this Section 8.1(d)(ii) if the Partnership or the Partnership GP is then in material breach of any of its representations, warranties, covenants or agreements contained in this Agreement; or

(iii) if prior to receipt of the Partnership Unitholder Approval, in response to an Intervening Event, the GP Board or the GP Conflicts Committee shall have determined to terminate this Agreement as contemplated in Section 6.3(b); provided, that the Partnership shall have complied in all material respects with Section 6.3(b).

Section 8.2 Effect of Termination. In the event of the termination of this Agreement as provided in Section 8.1, written notice thereof shall be given to the other party or parties, specifying the provision of this Agreement pursuant to which such termination is made, and this Agreement shall forthwith become null and void (other than the provisions in the last sentence of Section 6.6, the provisions in Section 6.8, this Section 8.2, Section 8.3 and Article IX, all of which shall survive termination of this Agreement), and, except as otherwise provided in this Section 8.2, there shall be no liability on the part of any of Parent, Merger Sub or the Partnership and the Partnership GP or their respective directors, officers and Affiliates; provided, however, that no such termination shall relieve any party hereto from (a) its obligation to pay the Parent Expenses, the Partnership Expenses, the Termination Payment, the Termination Amount, or the Break-Up Amount, or to make the amendment with respect to any Termination Amount or Break-Up Amount, in each case if, as and when required pursuant to Section 8.3, (b) any liability for any failure to consummate the Merger and the other transactions contemplated by this Agreement when required pursuant to this Agreement or (c) any liability for intentional fraud or a willful breach of any covenant or other agreement contained in this Agreement. For purposes of this Section 8.2, “willful breach” shall mean a material breach of this Agreement that is a consequence of a deliberate act or a deliberate failure to act by the breaching party with the knowledge that the taking of such act (or the failure to take such act) would (x) cause a material

breach of this Agreement and (y) prevent or materially delay the Closing. Notwithstanding the foregoing, in no event shall the Partnership GP or the Partnership have any liability for any matter set forth in the proviso of the preceding sentence for any action taken or omitted to be taken by the Partnership GP, the Partnership, any of their respective Subsidiaries or any of their respective Representatives at the direction of Parent, any of its Subsidiaries or any of their respective Representatives.

Section 8.3 Termination Amounts; Expenses.

(a) If this Agreement is validly terminated by the Partnership or Parent pursuant to the provisions of Section 8.1(b)(i) (Outside Date), then Parent shall pay to the Partnership (or its designated Affiliate) by wire transfer of immediately available funds to an account designated by the Partnership an amount equal to the Partnership Expenses, and such payment shall be made within three (3) Business Days after such termination.

(b) If (i) no Partnership Adverse Recommendation Change has occurred and (ii) this Agreement is validly terminated by the Partnership or Parent pursuant to the provisions of Section 8.1(b)(iii) (No Partnership Unitholder Approval), then Parent shall pay to the Partnership (or its designated Affiliate) by wire transfer of immediately available funds to an account designated by the Partnership an amount equal to the Partnership Expenses, and such payment shall be made within three (3) Business Days after such termination.

(c) If (i) no Parent Adverse Recommendation Change has occurred and (ii) this Agreement is validly terminated by the Partnership or Parent pursuant to the provisions of Section 8.1(b)(iv) (No Parent Stockholder Approval), then Parent shall pay to the Partnership (or its designated Affiliate) by wire transfer of immediately available funds to an account designated by the Partnership an amount equal to the Partnership Expenses, and such payment shall be made within three (3) Business Days after such termination. For purposes of this Section 8.3(c), the term “Partnership Expenses” shall have the meaning assigned to such term in Section 1.1(a), except that the reference to “$10,000,000” therein shall be replaced with “$20,000,000.”

(d) If this Agreement is validly terminated by the Partnership pursuant to Section 8.1(d)(ii) (Parent Uncured Breach), then Parent shall cause the Partnership GP to, within three (3) Business Days after such termination, execute the IDR Amendment in accordance with Section 8.3(m) with a reduction amount equal to the Termination Amount.

(e) If (i) after the date of this Agreement, an Alternative Proposal is publicly proposed or publicly disclosed prior to the Parent Stockholder Meeting, (ii) this Agreement is validly terminated by the Partnership or Parent pursuant to the provisions of Section 8.1(b)(iv) (No Parent Stockholder Approval), and (iii) at any time on or prior to the 12-month anniversary of such termination, Parent or any of its Subsidiaries enters into a definitive agreement in respect of an Alternative Proposal or consummates an Alternative Proposal, then Parent shall cause the Partnership GP to, concurrently with the consummation of such Alternative Proposal, execute the IDR Amendment in accordance with Section 8.3(m) with a reduction amount equal to the Break-Up Amount. For purposes of clause (iii) of this Section 8.3(e) only, the term “Alternative Proposal” shall have the meaning assigned to such term in Section 6.3(g)(ii) except that all references to “25%” therein shall be deemed to be references to “50%.”

(f) If this Agreement is validly terminated by Parent pursuant to Section 8.1(c)(iii) (Parent Superior Proposal), then Parent shall cause the Partnership GP to, concurrently with such termination, execute the IDR Amendment in accordance with Section 8.3(m) with a reduction amount equal to the Break-Up Amount.

(g) If this Agreement is validly terminated by Partnership pursuant to Section 8.1(d)(i) (Parent Adverse Recommendation Change), then Parent shall cause the Partnership GP to, within three (3) Business Days after such termination, execute the IDR Amendment in accordance with Section 8.3(m) with a reduction amount equal to the Break-Up Amount.

(h) If this Agreement is validly terminated by Parent pursuant to Section 8.1(c)(i) (Partnership Adverse Recommendation Change), then the Partnership shall, within three (3) Business Days after such termination, pay to Parent, by wire transfer of immediately available funds to an account designated by Parent, the Termination Payment; provided, however, that if the Intervening Event, in response to which the GP Conflicts Committee has made a Partnership Adverse Recommendation Change, is a material event, fact or circumstance, development or occurrence that is the direct and reasonably foreseeable result of a deliberate act by Parent (or its Affiliates), then the Partnership shall only be obligated to pay to Parent the Parent Expenses (in lieu of the Termination Payment), and such payment shall be made within three (3) Business Days after such termination.

(i) If this Agreement is validly terminated by Parent pursuant to Section 8.1(c)(ii) (Partnership Uncured Breach), then the Partnership shall, within three (3) Business Days after such termination, pay to the Parent by wire transfer of immediately available funds to an account designated by Parent, the Parent Expenses.

(j) If this Agreement is validly terminated by the Partnership pursuant to Section 8.1(d)(iii) (Partnership Intervening Event Termination Right), then the Partnership shall, within three (3) Business Days after such termination, pay to Parent, by wire transfer of immediately available funds to an account designated by Parent, the Break-Up Amount; provided, however, that if the Intervening Event, in response to which the GP Conflicts Committee has terminated this Agreement, is a material event, fact or circumstance, development or occurrence that is the direct and reasonably foreseeable result of a deliberate act by Parent (or its Affiliates), then the Partnership shall only be obligated to pay to Parent the Parent Expenses (in lieu of the Break-Up Amount), and such payment shall be made within three (3) Business Days after such termination.

(k) In no event shall Parent or the Partnership be required (i) to pay (or, in the case of Parent, to cause the Partnership GP to make the amendment contemplated by Section 8.3(m)) in respect of both a Termination Amount (or, in the case of the Partnership, a Termination Payment) and a Break-Up Amount or (ii) to pay the Termination Payment, the Termination Amount, or the Break-Up Amount (or cause the Partnership GP to make the amendment contemplated by Section 8.3(m)) on more than one occasion. In the event that Parent pays the Partnership Expenses pursuant to this Section 8.3, then any reduction amount in respect of any Termination Amount or Break-Up Amount required to be included in the IDR Amendment under this Section 8.3 shall be reduced by the amount of the Partnership Expenses previously paid. In the event that the Partnership pays the Parent Expenses pursuant to this

Section 8.3, then any Termination Payment or Break-Up Amount required to be paid by the Partnership under this Section 8.3 shall be reduced by the amount of the Parent Expenses previously paid.

(l) The parties acknowledge that payment of the Parent Expenses, the Partnership Expenses, the Termination Payment, the Termination Amount or the Break-Up Amount (or any amendment pursuant to Section 8.3(m) in respect of the Termination Amount or the Break-Up Amount), as applicable, if, as and when required pursuant to this Section 8.3, shall not constitute a penalty but will be liquidated damages, in a reasonable amount that will compensate the party receiving such amount in the circumstances in which it is payable for the efforts and resources expended and opportunities foregone while negotiating this Agreement and in reliance on this Agreement and on the expectation of the consummation of the Merger, which amount would otherwise be impossible to calculate with precision, and shall constitute the sole and exclusive remedy with respect thereto, except as expressly set forth in Section 8.2.

(m) If required under this Section 8.3, Parent shall cause the Partnership GP to execute an amendment to the Partnership Agreement providing for the reduction in distributions payable by the Partnership to the holders of the Incentive Distribution Rights (such amendment to be substantially in the form set forth in Section 8.3(m) of the Parent Disclosure Schedule, the “IDR Amendment”) in an amount equal to the amount so required under this Section 8.3 (after giving effect to any reduction contemplated by Section 8.3(k)), and, if the event giving rise to such payment obligation occurs and Parent makes such election, Parent hereby does consent to such amendment and agrees to cause any of its Subsidiaries that are required to consent to such amendment to do so.

ARTICLE IX

MISCELLANEOUS

Section 9.1 No Survival, Etc. The representations, warranties and agreements in this Agreement (including, for the avoidance of doubt, any schedule, instrument or other document delivered pursuant to this Agreement) shall terminate at the Effective Time or, except as otherwise provided in Section 8.2, upon the termination of this Agreement pursuant to Section 8.1, as the case may be, except that the agreements set forth in Article I, Article II, Article III and the last sentence of Section 6.6, Section 6.8 and Section 6.10 and any other agreement in this Agreement that contemplates performance after the Effective Time shall survive the Effective Time.

Section 9.2 Amendment or Supplement. At any time prior to the Effective Time, this Agreement may be amended or supplemented in any and all respects, whether before or after receipt of the Partnership Unitholder Approval and the Parent Stockholder Approval, by written agreement of the parties hereto, by action taken or authorized by the Parent Board or Parent Special Committee, as the case may be, and the GP Board; provided, however, that the GP Board may not take or authorize any such action unless it has first referred such action to the GP Conflicts Committee for its consideration, and permitted the GP Conflicts Committee not less than two (2) Business Days to make a recommendation to the GP Board with respect thereto (for the avoidance of doubt, the GP Board shall in no way be obligated to follow the recommendation of the GP Conflicts Committee and

the GP Board shall be permitted to take action following the expiration of such two (2) Business Day period); provided, further, that following receipt of the Partnership Unitholder Approval or the Parent Stockholder Approval, there shall be no amendment or change to the provisions of this Agreement which by applicable Law or stock exchange rule would require further approval by the Limited Partners or Parent Stockholders, as applicable, without such approval.

Section 9.3 GP Board Consent. Unless otherwise expressly set forth in this Agreement, whenever a determination, decision, approval or consent of the Partnership or Partnership GP is required pursuant to this Agreement, such determination, decision, approval or consent must be authorized by the GP Board; provided, however, that the GP Board may not take or authorize any such action unless it has first referred such action to the GP Conflicts Committee for its consideration, and permitted the GP Conflicts Committee not less than two (2) Business Days to make a recommendation to the GP Board with respect thereto.

Section 9.4 Extension of Time, Waiver, Etc. At any time prior to the Effective Time, any party may, subject to applicable Law, (a) waive any inaccuracies in the representations and warranties of any other party hereto, (b) extend the time for the performance of any of the obligations or acts of any other party hereto, (c) waive compliance by the other party with any of the agreements contained herein or, except as otherwise provided herein, waive any of such party’s conditions or (d) make or grant any consent under this Agreement; provided, however, that, prior to the Partnership Unitholder Approval, the GP Board may not take or authorize any such action unless it has first referred such action to the GP Conflicts Committee for its consideration, and permitted the GP Conflicts Committee not less than two (2) Business Days to make a recommendation to the GP Board with respect thereto (for the avoidance of doubt, the GP Board shall in no way be obligated to follow the recommendation of the GP Conflicts Committee and the GP Board shall be permitted to take action following the expiration of such two (2) Business Day period) and, following the Partnership Unitholder Approval, the GP Board may not take or authorize any such action without the prior written consent of the GP Conflicts Committee. Notwithstanding the foregoing, no failure or delay by the Partnership, the Partnership GP, Parent or Merger Sub in exercising any right hereunder shall operate as a waiver thereof nor shall any single or partial exercise thereof preclude any other or further exercise thereof or the exercise of any other right hereunder. Any agreement on the part of a party hereto to any such extension or waiver shall be valid only if set forth in an instrument in writing signed on behalf of such party.

Section 9.5 Assignment. Neither this Agreement nor any of the rights, interests or obligations hereunder shall be assigned, in whole or in part, by operation of Law or otherwise, by any of the parties without the prior written consent of the other parties, except that Merger Sub may assign, in its sole discretion, any of or all its rights, interests and obligations under this Agreement to any wholly-owned Subsidiary of Parent, but no such assignment shall relieve Parent or Merger Sub of any of its obligations hereunder. Subject to the preceding sentence, this Agreement shall be binding upon, inure to the benefit of, and be enforceable by, the parties hereto and their respective successors and permitted assigns. Any purported assignment not permitted under this Section 9.5 shall be null, void and ineffective.

Section 9.6 Counterparts. This Agreement may be executed in counterparts (each of which shall be deemed to be an original but all of which taken together shall constitute

one and the same agreement) and shall become effective when one or more counterparts have been signed by each of the parties and delivered to the other parties. Signatures to this Agreement transmitted by facsimile transmission, by electronic mail in “portable document format” (“.pdf”) form, or by any other electronic means intended to preserve the original graphic and pictorial appearance of a document, will have the same effect as physical delivery of the paper document bearing the original signature.

Section 9.7 Entire Understanding; No Third-Party Beneficiaries. This Agreement, the Partnership Disclosure Schedule, the Parent Disclosure Schedule and any certificates delivered by any party pursuant to this agreement (a) constitute the entire agreement and understanding, and supersede all other prior agreements and understandings, both written and oral, among the parties with respect to the subject matter of this Agreement and thereof and (b) shall not confer upon any Person other than the parties hereto any rights (including third-party beneficiary rights or otherwise) or remedies hereunder, except for, in the case of clause (b), the provisions of Section 6.7 and Section 9.12. Notwithstanding anything to the contrary in this Agreement, Section 9.8 and Section 9.12 shall be for the benefit of, and enforceable by, any financing sources or lender providing financing in connection with the Merger.

Section 9.8 Governing Law; Jurisdiction; Waiver of Jury Trial.

(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, 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); provided, however, each of the parties hereto irrevocably consents and agrees that any legal action or proceeding arising out of or in connection with any debt financing in connection with the Merger shall be brought only in the Supreme Court of the State of New York, County of New York, Borough of Manhattan, or, if under applicable Laws exclusive jurisdiction is vested in the federal courts, the United States District Court for the Southern District of New York (and appellate courts thereof). Each of the parties hereto 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 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 9.8, (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 (A) the suit, action or proceeding in such court is brought in an inconvenient forum, (B) the venue of such suit, action or proceeding is improper or (C) this Agreement, or the subject matter hereof, may not be enforced in or by such courts.

(c) EACH PARTY 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 BY THIS AGREEMENT OR THE ACTIONS OF ANY PARTY IN THE NEGOTIATION, ADMINISTRATION, PERFORMANCE AND ENFORCEMENT OF THIS AGREEMENT AND THE TRANSACTIONS CONTEMPLATED BY THIS AGREEMENT.

Section 9.9 Specific Performance. 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 9.9 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 (a) either party has an adequate remedy at law or (b) 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 9.9, and each party irrevocably waives any right it may have to require the obtaining, furnishing or posting of any such bond or similar instrument.

Section 9.10 Notices. All notices and other communications hereunder must be in writing and will be deemed duly given if delivered personally or by email transmission, or mailed through a nationally recognized overnight courier or registered or certified mail (return receipt requested), postage prepaid, to the parties at the following addresses (or at such other address for a party as specified by like notice, provided, however, that notices of a change of address will be effective only upon receipt thereof):

Section 9.12 Non-Recourse.
