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

Each of the Merger, the KMR Merger and the EPB Merger shall be consummated substantially concurrently on the same date in the sequence set forth on Section 1.2 of the Parent Disclosure Schedule. 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, the Partnership and Parent will cause each of a certificate of merger, executed in accordance with the relevant provisions of the Partnership Agreement, the DRULPA and the DLLCA (the “Certificate of Merger”), and the Charter Amendment, executed in accordance with the relevant provisions of the DGCL 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 the Partnership 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”). The Charter Amendment shall be filed with the Secretary of State of the State of Delaware prior to the filing of the Certificate of Merger and shall become effective at or prior to the Effective Time.

Section 1.6. Organizational Documents of Parent. The certificate of incorporation of Parent shall be amended prior to the Effective Time as set forth in Exhibit A (the “Charter Amendment”), and the certificate of incorporation of Parent, as amended by such Charter Amendment, shall be the certificate of incorporation of Parent until thereafter amended or changed as provided herein or by applicable Law, consistent with the obligations set forth in Section 5.8(b).

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 the Partnership, the Partnership GP, the Partnership GP Delegate, Parent, Merger Sub or the holder of any securities of the Partnership or Merger Sub:

(a) Conversion of Common Units. Subject to Section 2.1(c), Section 2.2(h) and Section 2.5, each Common Unit issued and outstanding or deemed issued and outstanding in accordance with Section 2.4 as of immediately prior to the Effective Time shall be converted into the right, at the election of the holder of such Common Unit pursuant to Section 2.3, to receive any of the following consideration (the “Merger Consideration”):

(i) Mixed Election Units. Each Common Unit with respect to which an election to receive a combination of stock and cash (a “Mixed Election”) has been properly made and not properly revoked pursuant to Section 2.3 (each, a “Mixed Consideration Election Unit”) and each No Election Unit (as that term is defined in Section 2.3(b)) shall be converted into the right to receive the combination (which combination shall hereinafter be referred to as the “Per Unit Mixed Consideration”) of (x) $10.77 in cash without interest (the “Per Unit Mixed Consideration Cash Amount”) and (y) 2.1931 shares of validly issued, fully paid and nonassessable Parent Class P Stock (such number of shares, the “Per Unit Mixed Election Stock Exchange Ratio”), in each case, subject to adjustment in accordance with Section 2.5.

(ii) Cash Election Units. Each Common Unit with respect to which an election to receive cash (a “Cash Election”) has been properly made and not properly revoked pursuant to Section 2.3 (each, a “Cash Election Unit”) shall be converted (provided that the Available Cash Election Amount (as defined below) equals or exceeds

the Cash Election Amount (as defined below)) into the right to receive $91.72 in cash without interest (the “Per Unit Cash Election Consideration”), subject to adjustment in accordance with this Section 2.2(c)(ii) and Section 2.5; provided, however, that if (A) the product of the number of Cash Election Units and the Per Unit Cash Election Consideration (such product being the “Cash Election Amount”) exceeds (B) the difference between (x) the product of the Per Unit Mixed Consideration Cash Amount and the total number of issued and outstanding Common Units immediately prior to the Effective Time (excluding Common Units that are to remain outstanding as provided for in Section 2.1(c) and including, for the avoidance of doubt, Common Units deemed outstanding pursuant to Section 2.4) minus (y) the product of the number of Mixed Consideration Election Units (provided that No Election Units shall be deemed to be Mixed Consideration Election Units for purposes of this Section 2.1(a)(ii)) and the Per Unit Mixed Consideration Cash Amount (the “Aggregate Mixed Consideration Cash Amount”) (such difference being the “Available Cash Election Amount”), then each Cash Election Unit shall be converted into a right to receive (1) an amount of cash (without interest) equal to the product of (p) the Per Unit Cash Election Consideration and (q) a fraction, the numerator of which shall be the Available Cash Election Amount and the denominator of which shall be the Cash Election Amount (such fraction being the “Cash Fraction”) and (2) a number of validly issued, fully paid and nonassessable shares of Parent Class P Stock equal to the product of (r) the Exchange Ratio and (s) one (1) minus the Cash Fraction.

(iii) Stock Election Units. Each Common Unit with respect to which an election to receive stock consideration (a “Stock Election”) has been properly made and not properly revoked pursuant to Section 2.3 (each, a “Stock Election Unit”) shall be converted (provided that the Cash Election Amount equals or exceeds the Available Cash Election Amount), into the right to receive 2.4849 shares of validly issued, fully paid and nonassessable Parent Class P Stock (the “Exchange Ratio”), subject to adjustment in accordance with this Section 2.1(a)(iii) and Section 2.5 (the “Per Unit Stock Consideration”); provided, however, that if the Available Cash Election Amount exceeds the Cash Election Amount, then each Stock Election Unit shall be converted into the right to receive (A) an amount of cash (without interest) equal to the amount of such excess divided by the number of Stock Election Units and (B) a number of validly issued, fully paid and nonassessable shares of Parent Class P Stock equal to the product of (x) the Exchange Ratio and (y) a fraction, the numerator of which shall be the Per Unit Cash Election Consideration minus the amount calculated in clause (A) of this Section 2.1(a)(iii) and the denominator of which shall be the Per Unit Cash Election Consideration.

(b) Equity of Merger Sub. The membership 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 2.1(a). 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, the Partnership GP Delegate, Parent and any Subsidiaries of Parent, and the Partnership GP, the Partnership GP Delegate, Parent and any

Subsidiaries of Parent shall continue the existence of the Partnership (as the Surviving Entity) without dissolution.

(c) Treatment of Partnership-Owned Units and Parent-Owned Partnership Interests. Any 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 Units. All Partnership Interests, including the Partnership GP Interest, that are owned immediately prior to the Effective Time by the Partnership GP, the Partnership GP Delegate, Parent or any of its Subsidiaries shall 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 2.1(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 2.2(g) and cash in lieu of any fractional shares 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 or Book-Entry Unit in accordance with Section 2.2(c), without interest.

Section 2.2. 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. Promptly after the Effective Time, but in no event more than five (5) 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 as of the Effective Time whose Common Units were converted into the right to receive the Merger Consideration (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), 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 2.2(i)) to the Exchange Agent) in such customary forms as the Partnership and Parent may reasonably agree prior to the Effective Time, including, as applicable, instructions for use in effecting the surrender of Certificates (or effective affidavits of loss in lieu thereof pursuant to Section 2.2(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 2.2(h) and any dividends or distributions pursuant to Section 2.2(g).

(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 whose Common Units are converting into the right to receive the Merger Consideration at the Effective Time, shares of Parent Class P Stock (which shall be in non-certificated book-entry form unless a

physical certificate is specifically requested, following the Effective Time, by the holder of such shares of Parent Class P Stock) and an amount of cash in U.S. dollars sufficient to be issued and paid pursuant to Section 2.1, payable upon due surrender of the Certificates (or affidavits of loss in lieu thereof pursuant to Section 2.2(i) with respect to certificated Common Units) or Book-Entry Units 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 or other consideration as applicable sufficient to pay any dividends and other distributions pursuant to Section 2.2(g) and any shares of Parent Class P Stock or cash in U.S. dollars 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 shares representing Parent Class P Stock and any dividends or distributions pursuant to Section 2.2(g) 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 delivered by Parent at or prior to the Effective Time, 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 purpose other than to pay such Merger Consideration, cash in lieu of any fractional shares payable pursuant to Section 2.2(h) and any dividends and other distributions pursuant to Section 2.2(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 2.2(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 shares of Parent Class P Stock (which shall be in non-certificated book-entry form unless a physical certificate is specifically requested, following the Effective Time, by the holder of such shares of Parent Class P Stock) representing, in the aggregate, the whole number of shares of Parent Class P Stock that such holder has the right to receive in accordance with the provisions of this Article II, (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 any cash in lieu of any fractional shares payable pursuant to Section 2.2(h)) and (iii) such dividends or other distributions as such holder has the right to receive pursuant to Section 2.2(g). The Merger Consideration and such other amounts as reflected in the immediately preceding sentence shall be paid as promptly as practicable after receipt by the Exchange Agent of the Certificate (or affidavit of loss in lieu thereof pursuant to Section 2.2(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 amount as contemplated by Section 2.2(g).

(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 II.

(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 twelve (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 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. Notwithstanding the foregoing, Parent, Merger Sub and the Partnership shall not be liable to any holder of Common 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 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 shares of Parent Class P Stock 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 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 shares of Parent Class P Stock, if any, issued in exchange therefor (i) at the time of such surrender, all dividends and other distributions payable in respect of any such shares of Parent Class P Stock 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 shares of Parent Class P Stock 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 shares of Parent Class P Stock, all shares of Parent Class P Stock 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 certificates or scrip representing fractional shares of Parent Class P Stock shall be issued upon the surrender for exchange of Certificates or Book-Entry Units. Notwithstanding any other provision of this Agreement, each holder of Common Units converted into the right to receive the Merger Consideration pursuant to the Merger who would otherwise have been entitled to receive a fraction of a share of Parent Class P Stock (after taking into account all Certificates (or affidavits of loss in lieu thereof pursuant to Section 2.2(i)) or Book-Entry Units to be 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 shares 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 “share proceeds”) in one or more transactions of a number of shares of Parent Class P Stock, such number equal to the excess of (i) the aggregate number of shares of Parent Class P Stock to be delivered to the Exchange Agent by Parent pursuant to Section 2.2(b) over (ii) the aggregate number of whole shares of Parent Class P Stock to be distributed to the holders of Certificates and Book-Entry Units pursuant to Section 2.2(c) (such excess being, the “Excess Shares”). The parties acknowledge that payment of the cash share proceeds in lieu of issuing certificates or scrip for fractional 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 shares. As soon as practicable after the Effective Time, the Exchange Agent, as agent for the holders of the Common Units that would otherwise receive fractional shares of Parent Class P Stock, shall sell the Excess Shares at then-prevailing prices on the NYSE in the manner provided in this Section 2.2(h) and shall execute such sales in round lots to the extent practicable. Until the share proceeds of such sale or sales have been distributed to the holders of such Common Units, or the Exchange Fund is terminated, the Exchange Agent shall hold such share proceeds in trust for the benefit of the holders of such Common Units (the “Fractional Share Proceeds”). The Exchange Agent shall determine the portion of the Fractional Share Proceeds to which each holder of such Common Units shall be entitled, if any, by multiplying the amount of the aggregate share proceeds comprising the Fractional Share Proceeds by a fraction, the numerator of which is the amount of the fractional shares to which such holder of such Common Units would otherwise be entitled and the denominator of which is the aggregate amount of fractional shares to which all holders of such Common Units would otherwise be entitled. To the extent applicable, each holder of Common Units shall be deemed to have consented for U.S. federal income tax purposes (and to the extent applicable, state or local income tax purposes) to report the cash received for fractional shares in the Merger as a sale of a portion of the holder’s Common Units to Parent.

(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 and any dividends and other distributions pursuant to Section 2.2(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 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 Class P 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 shares of Parent Class P Stock, 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 2.3. Election Procedures.

(a) Election Form. An election form and other appropriate and customary transmittal materials (which shall specify with respect to certificated Common Units that delivery shall be effected, and risk of loss and title to the Certificates shall pass, only upon proper delivery of such Certificates to the Exchange Agent) in such form as Parent shall reasonably specify and as shall be reasonably acceptable to the Partnership (the “Election Form”) shall be mailed no less than thirty (30) days prior to the anticipated Closing Date or on such other date as Parent and the Partnership shall mutually agree (the “Mailing Date”) to each holder of record of Common Units as of the close of business on the fifth business day prior to the Mailing Date or such other date as mutually agreed to by Parent and the Partnership (the “Election Form Record Date”).

(b) Choice of Election. Each Election Form shall permit the holder (or the beneficial owner through appropriate and customary documentation and instructions) to specify (i) the number of such holder’s (or such beneficial owner’s) Common Units with respect to which such holder (or such beneficial owner) elects to receive (A) the Per Unit Mixed Consideration, (B) the Per Unit Stock Consideration or (C) the Per Unit Cash Election Consideration or (ii) that such holder (or such beneficial owner) makes no election with respect to such holder’s (or such beneficial owner’s) Common Units. Any Common Units with respect to which the Exchange Agent does not receive a properly completed Election Form during the period (the “Election Period”) from the Mailing Date to 5:00 p.m., New York time, on the second (2nd) business day prior to the Effective Time (the “Election Deadline”) shall be deemed to be No Election Units. Parent shall publicly announce the anticipated Election Deadline at least five (5) business days prior to the Election Deadline. If the Effective Time is delayed to a subsequent date, the Election Deadline shall be similarly delayed to a subsequent date (which shall be the second (2nd) business day prior to the Effective Time or such other date as mutually agreed to by Parent and the Partnership), and Parent shall promptly announce any such delay

and, when determined, the rescheduled Election Deadline. For the purposes of this Agreement, “No Election Unit” means each Common Unit for which no election to receive Per Unit Mixed Consideration, Per Unit Cash Election Consideration or Per Unit Stock Consideration has been properly made and received in accordance with the terms of this Section 2.3. For the avoidance of doubt, for purposes of this Section 2.3, references to Common Units shall include, or be deemed to include, Restricted Units.

(c) New Holders. Parent shall make available one or more Election Forms as may reasonably be requested from time to time by all persons who become holders or beneficial owners of Common Units during the Election Period, and the Partnership shall provide the Exchange Agent all information reasonably necessary for it to perform its duties as specified herein.

(d) Revocations; Exchange Agent. Any election shall have been properly made only if the Exchange Agent shall have actually received a properly completed Election Form during the Election Period. After a Cash Election, a Stock Election or a Mixed Election is validly made with respect to any Common Units, any subsequent transfer of such Common Units shall automatically revoke such election. Any Election Form may be revoked or changed by the person submitting it by written notice received by the Exchange Agent during the Election Period. In the event an Election Form is revoked, the Common Units represented by such Election Form shall be deemed to be No Election Units, except to the extent a subsequent election is properly made during the Election Period. Subject to the terms of this Agreement and of the Election Form, the Exchange Agent shall have reasonable discretion to determine whether any election, revocation or change has been properly or timely made and to disregard immaterial defects in the Election Forms, and any good faith decisions of the Exchange Agent regarding such matters shall be binding and conclusive. None of Parent or the Partnership or the Exchange Agent shall be under any obligation to notify any person of any defect in an Election Form.

Section 2.4. Treatment of Restricted Units; Termination of Partnership Equity Plan.

(a) As soon as reasonably practicable following the date of this Agreement, and in any event prior to the Effective Time, the GP Delegate Board (or, if appropriate, any committee administering the Partnership Equity Plan) will adopt resolutions, and the Partnership will take all other actions as may be necessary or required in accordance with applicable Law and the Partnership Equity Plan (including, the award agreements in respect of awards granted thereunder) to give effect to this Section 2.4 to provide that each Common Unit subject to forfeiture or restricted unit granted under the Partnership Equity Plan (each, a “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 Section 2.1, Section 2.2 and Section 2.3).

(b) Prior to the Effective Time, the Partnership GP Delegate shall take all actions necessary to terminate the Partnership Equity Plan, such termination to be effective at the Effective Time, and from and after the Effective Time, the Partnership Equity Plan shall be

terminated and no Restricted Units or other rights with respect to Common Units or other Partnership Interests shall be granted or be outstanding thereunder, it being understood that the terminations contemplated by this Agreement shall in no respect limit Parent’s obligations under this Section 2.4 with respect to Restricted Units granted prior to the Effective Time.

Section 2.5. Adjustments. Notwithstanding any provision of this Article II to the contrary, if between the date of this Agreement and the Effective Time the number of outstanding Common Units or shares of Parent Class P Stock shall have been changed into a different number of units or shares or a different class or series by reason of the occurrence or record date 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, the Per Unit Mixed Consideration Cash Amount, the Per Unit Cash Election Consideration, the Per Unit Stock Consideration, the Mixed Election Stock Exchange Ratio 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.

Section 2.6. No Dissenters’ Rights. No dissenters’ or appraisal rights shall be available with respect to the Merger or the other transactions contemplated by this Agreement.

(iii) during the Partnership Notice Period, the Partnership, through the GP Conflicts and Audit Committee, has negotiated, and has used reasonable best efforts to cause its financial advisors and outside legal counsel to negotiate, with Parent in good faith (to the extent Parent desires to negotiate) to make such adjustments in the terms and conditions of this Agreement so that the failure to effect such Partnership Adverse Recommendation Change would not be opposed to the best interests of the Partnership, after making a determination that the failure to effect such Partnership Adverse Recommendation Change would not be opposed to the best interests of the Public Unitholders; provided, that (x) the GP Conflicts and Audit Committee shall take into account all changes to the terms of this Agreement proposed by Parent in determining whether (1) in the case of Section 5.1(b)(i)(A), such Partnership Alternative Proposal continues to constitute a Partnership Superior Proposal or (2) in the case of Section 5.1(b)(i)(B), such Partnership Intervening Event continues to constitute a Partnership Intervening Event and (y) any material amendment to the terms of a Partnership Superior Proposal, if applicable, shall require a new notice pursuant to this Section 5.1(b) and a new Partnership Notice Period, except that such new Partnership Notice Period in connection with any material amendment shall be for one (1) business day from the time Parent receives such notice (as opposed to five (5) days).

(c) Parent shall, as soon as practicable following the date of this Agreement, establish a record date for, duly call, give notice of, convene and hold a special meeting of its stockholders (the “Parent Stockholder Meeting”) for the purpose of obtaining the Parent Stockholder Approval.

(i) (A) if Parent has received a written Parent Alternative Proposal that Parent’s Board of Directors believes is bona fide and Parent’s Board of Directors (after consultation with its financial advisor and outside legal counsel) determines in good faith that (x) such Parent Alternative Proposal constitutes a Parent Superior Proposal and (y) the failure to take such action would be inconsistent with its fiduciary duties to stockholders under applicable Law (any Parent Adverse Recommendation Change in connection with a Parent Superior Proposal, a “Parent Superior Proposal Adverse Recommendation Change”); or (B) in response to a Parent Intervening Event if the Board of Directors of Parent determines in good faith (after consultation with the Parent’s financial advisor and outside legal counsel) that the failure to take such action would be inconsistent with its fiduciary duties to stockholders under applicable Law;

(ii) Parent has provided prior written notice to the Partnership, the Partnership GP and the Partnership GP Delegate (A) in the case of Section 5.1(c)(i)(A), (x) stating that the Parent’s Board of Directors, after consultation with its financial advisor and outside legal counsel, has concluded that such Parent Alternative Proposal constitutes a Parent Superior Proposal, and (y) including a description of the material terms of such Parent Superior Proposal, together with a copy of the Acquisition Agreement for such Parent Superior Proposal in final form and any other relevant proposed transaction agreements; or (B) in the case of Section 5.1(c)(i)(B), specifying in reasonable detail the material events giving rise to the Parent Intervening Event, in the case of each of (A) and (B), at least five (5) 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 five (5) days prior to the Parent Stockholder Meeting, in which case Parent shall provide as much notice as is reasonably practicable (the period inclusive of all such days, the “Parent Notice Period”); and

(iii) during the Parent Notice Period, the Board of Directors of Parent has negotiated, and has used reasonable best efforts to cause its financial advisors and outside legal counsel to negotiate, with the Partnership, the Partnership GP and the Partnership GP Delegate in good faith (to the extent any of them desires 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 the fiduciary duties of the Parent’s Board of Directors to stockholders under applicable Law; provided, that (x) the Parent’s Board of Directors shall take into account all changes to the terms of this Agreement proposed by the Partnership, the Partnership GP and the Partnership GP Delegate in determining whether (1) in the case of Section

5.1(c)(i)(A), such Parent Alternative Proposal continues to constitute a Parent Superior Proposal or (2) in the case of Section 5.1(c)(i)(B), such Parent Intervening Event continues to constitute a Parent Intervening Event and (y) any material amendment to the terms of a Parent Superior Proposal, if applicable, shall require a new notice pursuant to this Section 5.1(c) and a new Parent Notice Period, except that such new Parent Notice Period in connection with any material amendment shall be for one (1) business day from the time the Partnership, the Partnership GP and the Partnership GP Delegate receive such notice (as opposed to five (5) days).

Without limiting the generality of the foregoing, Parent’s obligations pursuant to the first sentence of this Section 5.1(c) shall not be affected by (i) the commencement, public proposal, public disclosure or communication to the Parent of any Parent Alternative Proposal or (ii) a Parent Adverse Recommendation Change. Notwithstanding anything in this Agreement to the contrary, Parent may postpone or adjourn the Parent Stockholder Meeting (i) to solicit additional proxies for the purpose of obtaining the Parent Stockholder Approval, (ii) for the absence of quorum, (iii) to allow reasonable additional time for the filing and/or mailing of any supplemental or amended disclosure that Parent has determined, after consultation with outside legal counsel, is necessary under applicable Law and for such supplemental or amended disclosure to be disseminated and reviewed by the stockholders of Parent prior to the Parent Stockholder Meeting and (iv) if Parent has delivered any notice contemplated by the provisions of this Section 5.1(c) and the time periods contemplated by such provisions have not expired.

(d) The parties shall use their reasonable best efforts to hold the Partnership Unitholder Meeting and the Parent Stockholder Meeting on the same day.

(e) Unless this Agreement is validly terminated in accordance with Article VII, the Partnership shall submit this Agreement to its Limited Partners for approval at the Partnership Unitholder Meeting even if the GP Delegate Board, the GP Conflicts and Audit Committee or the GP Board shall have effected a Partnership Adverse Recommendation Change.

(f) Unless this Agreement is validly terminated in accordance with Article VII, Parent shall submit the Parent Stock Issuance and the adoption of the Charter Amendment for approval at the Parent Stockholder Meeting even if the Parent’s Board of Directors shall have effected a Parent Adverse Recommendation Change.

Except as otherwise provided in this Agreement, the representations, warranties and agreements of each party hereto shall remain operative and in full force and effect regardless of any investigation made by or on behalf of any other party hereto, whether prior to or after the execution of this Agreement. The representations, warranties and agreements in this Agreement shall terminate at the Effective Time or, except as otherwise provided in Section 7.2, upon the termination of this Agreement pursuant to Section 7.1, as the case may be, except that the agreements set forth in Article II, the last sentence of Section 5.7, Section 5.8, Section 5.10 and any other agreement in this Agreement that contemplates performance after the Effective Time shall survive the Effective Time.

Section 8.2. 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 Parent’s Board of Directors, the GP Delegate Board and the GP Board; provided, however, that the GP Board and the GP Delegate Board may not take or authorize any such action unless it has first referred such action to the GP Conflicts and Audit Committee for its consideration, and permitted the GP Conflicts and Audit Committee not less than two (2) business days to make a recommendation to the GP Board and the GP Delegate Board with respect thereto (for the avoidance of doubt, the GP Board and the GP Delegate Board shall in no way be obligated to follow the recommendation of the GP Conflicts and Audit Committee and the GP Board and the GP Delegate 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 and Parent Stockholder Approval, there shall be no amendment or change to the provisions of this Agreement which by Law or

stock exchange rule would require further approval by the Limited Partners or the stockholders of Parent, as applicable, without such approval. Unless otherwise expressly set forth in this Agreement, whenever a determination, decision, approval or consent of the Partnership, the Partnership GP or the Partnership GP Delegate is required pursuant to this Agreement, such determination, decision, approval or consent must be authorized by the GP Board and the GP Delegate Board; provided, however, that the GP Board and the GP Delegate Board may not take or authorize any such action unless it has first referred such action to the GP Conflicts and Audit Committee for its consideration, and permitted the GP Conflicts and Audit Committee not less than two (2) business days to make a recommendation to the GP Board with respect thereto.

Notwithstanding the foregoing, no failure or delay by the Partnership, the Partnership GP, the Partnership GP Delegate, 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 8.4. 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; provided, that if such assignment is to a wholly owned Subsidiary of the Company that is created or organized outside the United States and would result in amounts being deducted or withheld for Taxes pursuant to Section 2.2(j) in excess of the amounts that would have been so deducted or withheld in the absence of such assignment, then the Merger Consideration shall be increased as necessary so that after such deduction or withholding has been made (including any deduction or withholding applicable to additional sums payable under this Section 8.4, the applicable Person receives an amount equal to the sum it would have received had no such assignment been made). 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 shall be null and void.

Section 8.6. Entire Agreement; No Third-Party Beneficiaries. This Agreement, the Confidentiality Agreement, the Partnership Disclosure Schedule and the Parent Disclosure Schedule (a) constitute the entire agreement, 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), (i) the provisions of Section 5.8 and Section 8.13 and (ii) the right of the holders of Common Units to receive the Merger Consideration after the Closing (a claim by the holders of Common Units with respect to which may not be made unless and until the Closing shall have occurred). Notwithstanding anything to the contrary in this Agreement, Section 8.7 and Section 8.13 shall be for the benefit of, and enforceable by, any financing sources or lender providing financing in connection with the Merger.

Section 8.7. 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 that, notwithstanding the foregoing, 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 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. Each of the parties hereto irrevocably consents to the service of the summons and complaint and any

other process in any action or proceeding relating to the transactions contemplated by this Agreement, on behalf of itself or its property, by personal delivery of copies of such process to such party at the addresses set forth in Section 8.9. Nothing in this Section 8.7 shall affect the right of any party to serve legal process in any other manner permitted by Law.

(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 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 8.8. Specific Performance.

(a) 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.

Section 8.9. Notices. All notices and other communications hereunder shall be in writing and shall be deemed given (a) upon personal delivery to the party to be notified; (b) when received when sent by email or facsimile by the party to be notified, provided, however, that notice given by email or facsimile shall not be effective unless either (i) a duplicate copy of such email or fax notice is promptly given by one of the other methods described in this Section 8.9 or (ii) the receiving party delivers a written confirmation of receipt for such notice either by email or fax or any other method described in this Section 8.9; or (c) when delivered by an courier (with confirmation of delivery); in each case to the party to be notified at the following address:

Further, prior drafts of this Agreement or the fact that any clauses have been added, deleted or otherwise modified from any prior drafts of this Agreement shall not be used as an aide of construction or otherwise constitute evidence of the intent of the parties; and no presumption or burden of proof shall arise favoring or disfavoring any party hereto by virtue of such prior drafts.
