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

ARTICLE I

The Merger

Section 1.1. The Merger. Upon the terms and subject to the conditions set forth in this Agreement, and in accordance with the 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”).

Section 1.2. Closing. Subject to the provisions of Article VI, the closing of the Merger (the “Closing”) shall take place at the offices of Weil, Gotshal & Manges LLP, 700 Louisiana Street, Suite 1700, Houston, Texas 77002 at 10:00 A.M., Houston, Texas time, on the second (2nd) business day after the satisfaction or waiver of the conditions set forth in Article VI (other than conditions that by their nature are to be satisfied at the Closing, but subject to the satisfaction or waiver of those conditions), or at such other place, date and time as the Partnership and Parent shall agree. Each of the Merger, the KMR Merger and the KMP 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 1.4. Effects of the Merger. The Merger shall have the effects set forth in this Agreement, the Partnership Agreement and the applicable provisions of the DRULPA and the DLLCA.

Section 1.5. Organizational Documents of the Surviving Entity. At the Effective Time, the certificate of limited partnership of the Partnership and the Partnership Agreement shall remain unchanged and shall be the certificate of limited partnership and Partnership Agreement of the Surviving Entity, until duly amended in accordance with applicable Law and the terms of the Partnership Agreement.

2

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

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, 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) $4.65 in cash without interest (the “Per Unit Mixed Consideration Cash Amount”) and (y) 0.9451 of a share of validly issued, fully paid and nonassessable Parent Class P Stock (such fraction of a share, 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 $39.53 in cash without interest (the “Per Unit Cash Election Consideration”), subject to adjustment in accordance with this Section 2.1(a)(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, Restricted Units pursuant to the terms and conditions of 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

3

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 1.0711 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, Parent and any Subsidiaries of Parent, and the Partnership GP, 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, 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

4

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, 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

5

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 by mail 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

6

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

7

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.

(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

8

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

9

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 Board (or, if appropriate, any committee administering the Long-Term Incentive 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 Long-Term Incentive 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 Long-Term Incentive 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 shall take all actions necessary to terminate the Long-Term Incentive Plan, such termination to be effective at the Effective Time, and from and after the Effective Time, the Long-Term Incentive 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

10

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.

(a) The Partnership GP and the Partnership shall, and shall cause their respective Subsidiaries and the foregoing shall use their commercially reasonable best efforts to cause their respective directors, officers, employees, investment bankers, financial advisors, attorneys, accountants, agents and other representatives (collectively, “Representatives”) to, immediately cease and cause to be terminated any discussions or negotiations with any Person conducted heretofore with respect to an Alternative Proposal, and immediately prohibit any access by any Person (other than Parent and its Representatives) to any confidential information relating to a possible Alternative Proposal. Except as permitted by this Section 5.3, the Partnership and the Partnership GP shall not, and shall cause their respective Subsidiaries and the foregoing shall use their commercially 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) except for a confidentiality agreement permitted pursuant to Section 5.3(b), enter into any confidentiality agreement, merger agreement, letter of intent, agreement in principle, unit purchase agreement, asset purchase agreement or unit exchange agreement, option agreement or other similar agreement relating to an Alternative Proposal (an “Acquisition Agreement”) or (iii) withdraw, modify or qualify, or propose publicly to withdraw, modify or qualify, in a manner adverse to Parent, the Partnership Board Recommendation or publicly recommend the approval or adoption of, or publicly approve or adopt, or propose to publicly recommend, approve or adopt, any Alternative Proposal (the taking of any action described in clause (iii) being referred to as a “Partnership Adverse Recommendation Change”). Without limiting the foregoing, it is understood that any violation of the foregoing restrictions by the Partnership’s or the Partnership GP’s Subsidiaries, or the Partnership’s or the Partnership GP’s Representatives, other than any violation caused by or at the direction of Parent or any Representative of Parent or any of its Subsidiaries (including any Representative of Parent that is also a Representative of the Partnership, the Partnership GP or any of their respective Subsidiaries), shall be deemed to be a breach of this Section 5.3 by the Partnership.

(b) Notwithstanding anything to the contrary contained in Section 5.3(a), if at any time following the date of this Agreement and prior to obtaining the Partnership Unitholder Approval, (i) the Partnership has received a written Alternative Proposal that the GP Board believes is bona fide, (ii) the GP Board, after consultation with its financial advisor and outside legal counsel, determines in good faith that such Alternative Proposal constitutes or could reasonably be expected to lead to or result in a Superior Proposal and (iii) such Alternative Proposal did not result from a material breach of this Section 5.3, then the Partnership and the Partnership GP may, subject to clauses (x) and (y) below, (A) furnish information, including confidential information, with respect to the Partnership and its Subsidiaries to the Person

32

making such Alternative Proposal and (B) participate in discussions or negotiations regarding such Alternative Proposal; provided that (x) the Partnership and the Partnership GP and their respective Subsidiaries will not, and will use reasonable best efforts to cause their respective Representatives not to, disclose any non-public information to such Person unless the Partnership has, or first enters into, a confidentiality agreement with such Person with confidentiality provisions that are not less restrictive in the aggregate to such Person than the provisions of the Confidentiality Agreement are to Parent and (y) the Partnership and the Partnership GP will provide to Parent non-public information with respect to the Partnership and its Subsidiaries that was not previously provided or made available to Parent prior to or substantially concurrent with providing or making available such non-public information to such other Person.

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

(d) Notwithstanding anything to the contrary in this Agreement, at any time prior to obtaining the Partnership Unitholder Approval, and subject to compliance in all material respects with this Section 5.3(d), the GP Board or the GP Conflicts Committee may make a Partnership Adverse Recommendation Change if the GP Board or the GP Conflicts Committee, as applicable, determines in good faith (after consultation with its financial advisor and outside legal counsel) that the failure to take such action would be inconsistent with the best interests of the Partnership; provided, however, that neither the GP Board nor the GP Conflicts Committee may effect a Partnership Adverse Recommendation Change pursuant to the foregoing unless:

(i) The GP Board or the GP Conflicts Committee, as applicable, has provided prior written notice to Parent specifying in reasonable detail the reasons for such action, including, if a reason for the Partnership Adverse Recommendation Change is an Alternative Proposal, a description of the material terms of such Alternative Proposal, at least three (3) days in advance of its intention to take such action with respect to a Partnership Adverse Recommendation Change, unless (A) at the time such notice is otherwise required to be given there are less than three (3) days prior to the Partnership Unitholder Meeting, in which case the GP Board or the GP Conflicts Committee, as applicable, shall provide as much notice as is reasonably practicable (it

33

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 5.3(d) 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 three (3) days) or (B) if a reason for the Partnership Adverse Recommendation Change is any amendment or supplement to this Agreement agreed to, or any determination, decision, approval or consent required by this Agreement made or granted by, or any waiver or extension under this Agreement granted by, the GP Board, in each case without the prior recommendation of the GP Conflicts Committee in accordance with Section 8.2 or Section 8.3, as applicable, in which case the GP Conflicts Committee shall be required to provide one (1) day notice (the period inclusive of all such days, the “Partnership Notice Period”); and

(ii) during the Partnership Notice Period, the GP Conflicts Committee or the GP Board, as applicable, 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 inconsistent with the best interests of the Partnership.

(e) Any Partnership Adverse Recommendation Change effected by the GP Conflicts Committee shall invalidate and rescind any prior “Special Approval” (as defined in the Partnership Agreement) of this Agreement and the transactions contemplated by this Agreement.

(f) For purposes of this Agreement:

(i) “Alternative Proposal” means any inquiry, proposal or offer from any Person or “group” (as defined in Section 13(d) of the Exchange Act), other than Parent and its Subsidiaries, relating to any (A) 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 the Partnership and its Subsidiaries (including securities of Subsidiaries) equal to twenty-five percent (25%) or more of the Partnership’s consolidated assets or to which twenty-five percent (25%) or more of the Partnership’s revenues or earnings on a consolidated basis are attributable, (B) 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 the Partnership, (C) 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 the Partnership or (D) merger, consolidation, unit exchange, share exchange, business combination, recapitalization, liquidation, dissolution or similar transaction involving the Partnership which is structured to permit such Person or group to acquire beneficial ownership of at least twenty-five percent (25%) of the Partnership’s consolidated assets or outstanding equity interests; in each case, other than the transactions contemplated by this Agreement.

34

(ii) “Superior Proposal” means a bona fide written offer, obtained after the date of this Agreement and not in material breach of this Section 5.3, to acquire, directly or indirectly, more than fifty percent (50%) of the outstanding equity securities of the Partnership or assets of the Partnership and its Subsidiaries on a consolidated basis, made by a third party, which is on terms and conditions which the GP Board determines in its good faith to be more favorable to the Partnership than the transactions contemplated by this Agreement, taking into account all financial, legal, financing, regulatory and other aspects of such offer and any changes to the terms of this Agreement that as of the time of determination had been committed to by Parent in writing.

(g) Nothing contained in this Agreement shall prevent the Partnership or the GP Conflicts Committee or the GP Board from issuing a “stop, look and listen” communication pursuant to Rule 14d-9(f) under the Exchange Act or complying with Rule 14d-9 and Rule 14e-2 under the Exchange Act with respect to an Alternative Proposal if the GP Conflicts Committee determines in good faith (after consultation with outside legal counsel) that its failure to do so would be inconsistent with the best interests of the Partnership or applicable Law; provided that any Partnership Adverse Recommendation Change may only be made in accordance with Section 5.3(d). For the avoidance of doubt, a public statement that describes the Partnership’s receipt of an Alternative Proposal and the operation of this Agreement with respect thereto shall not be deemed a Partnership Recommendation Change.

Section 5.4. Reasonable Best Efforts.

(a) Subject to the terms and conditions of this Agreement (and, in the case of Parent and its Subsidiaries, the terms and conditions of the KMP Merger Agreement and the KMR Merger Agreement), Parent, on the one hand, and each of the Partnership and the Partnership GP, on the other hand, shall cooperate with the other and use and shall cause their respective Subsidiaries to use (it being understood that with respect to KMP, its general partner and KMR and their respective Subsidiaries, Parent’s obligations shall only apply to the extent such obligation is appropriate under the Organizational Documents of KMP, its general partner and KMR and their respective Subsidiaries) its reasonable best efforts to (i) take, or cause to be taken, all actions, and do, or cause to be done, all things, necessary, proper or advisable to cause the conditions to the Closing to be satisfied as promptly as practicable (and in any event no later than the Outside Date), including, for the avoidance of doubt, in the case of Parent until the Effective Time or the termination of this Agreement, (A) voting or causing to be voted all Common Units beneficially owned by Parent and such Subsidiaries and controlled Affiliates in favor of the Merger at the Partnership Unitholder Meeting unless there is a Partnership Adverse Recommendation Change, (B) voting or causing to be voted all voting securities beneficially owned by Parent and such Subsidiaries and controlled Affiliates in KMP in favor of the KMP Merger at the KMP Unitholder Meeting and (C) voting or causing to be voted to the extent permitted under the Organizational Documents of KMR, all voting securities beneficially owned by Parent and such Subsidiaries and its controlled Affiliates in KMR in favor of the KMR Merger at the KMR Shareholder Meeting, and to consummate and make effective, in the most expeditious manner practicable, the transactions contemplated by this Agreement, including preparing and filing as promptly as practicable and advisable all documentation to effect all necessary filings, notifications, notices, petitions, statements, registrations, submissions of information, applications and other documents (including any required or recommended filings

35

under applicable Antitrust Laws), (ii) obtain promptly (and in any event no later than the Outside Date) all approvals, consents, clearances, expirations or terminations of waiting periods, registrations, permits, authorizations and other confirmations from any Governmental Authority or third party necessary, proper or advisable to consummate the transactions contemplated by this Agreement and (iii) defend any lawsuits or other legal proceedings, whether judicial or administrative, challenging this Agreement or the consummation of the transactions contemplated by this Agreement. For purposes of this Agreement, “Antitrust Laws” means the Sherman Act, as amended, the Clayton Act, as amended, the HSR Act, the Federal Trade Commission Act, as amended, and all other applicable Laws issued by a Governmental Authority that are designed or intended to prohibit, restrict or regulate actions having the purpose or effect of monopolization or restraint of trade or lessening of competition.

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

(c) Except as expressly prohibited in this Agreement, Parent shall be permitted to perform its obligations and exercise its rights under the KMP Merger Agreement and the KMR Merger Agreement, and no such performance or exercise shall constitute a breach or violation of any of the provisions of this Agreement; provided, however, that any such performance or exercise may constitute a breach of a provision of this Agreement to the extent such provision of this Agreement prohibits Parent from taking any action or requires Parent to take any action, and such performance or exercise results in a breach of such obligation contained in such provision of this Agreement.

Section 5.5. Public Announcements. The initial press release with respect to the execution of this Agreement shall be a joint press release to be reasonably agreed upon by Parent and the Partnership. Thereafter, neither the Partnership nor Parent shall issue or cause the publication of any press release or other public announcement (to the extent not previously issued or made in accordance with this Agreement) with respect to this Agreement or the transactions contemplated by this Agreement without the prior consent of the other party (which consent shall not be unreasonably withheld, conditioned or delayed), except as may be required

36

by Law or by any applicable listing agreement with the NYSE or other national securities exchange as determined in the good faith judgment of the party proposing to make such release (in which case such party shall not issue or cause the publication of such press release or other public announcement without prior consultation with the other party); provided, however, that the Partnership shall not be required by this Section 5.5 to consult with any other party with respect to a public announcement in connection with the receipt and existence of an Alternative Proposal that the GP Board believes in good faith is bona fide and matters related thereto or a Partnership Adverse Recommendation Change but nothing in this proviso shall limit any obligation of the GP Board or the GP Conflicts Committee under Section 5.3(d) to negotiate with Parent in good faith; provided, further, that each party and their respective controlled affiliates may make statements that are consistent with statements made in previous press releases, public disclosures or public statements made by Parent or the Partnership in compliance with this Section 5.5.

Section 5.6. Access to Information; Confidentiality. Upon reasonable notice and subject to applicable Laws relating to the exchange of information, each party shall, and shall cause each of its Subsidiaries to afford to the other party and its Representatives reasonable access during normal business hours (and, with respect to books and records, the right to copy) to all of its and its Subsidiaries’ properties, commitments, books, Contracts, records and correspondence (in each case, whether in physical or electronic form), officers, employees, accountants, counsel, financial advisors and other Representatives. Except for disclosures permitted by the terms of the Confidentiality Agreement, dated as of July 20, 2014, between Parent and the Partnership (as it may be amended from time to time, the “Confidentiality Agreement”), each party and its Representatives shall hold information received from the other party pursuant to this Section 5.6 in confidence in accordance with the terms of the Confidentiality Agreements.

Section 5.7. Indemnification and Insurance.

(a) For purposes of this Section 5.7, (i) “Indemnified Person” shall mean any person who is now, or has been or becomes at any time prior to the Effective Time, an officer, director or employee of the Partnership or any of its Subsidiaries or the Partnership GP and also with respect to any such Person, in their capacity as a director, officer, employee, member, trustee or fiduciary of another corporation, foundation, partnership, joint venture, trust, pension or other employee benefit plan or enterprise (whether or not such other entity or enterprise is affiliated with the Partnership) serving at the request of or on behalf of the Partnership or the Partnership GP or any of their respective Subsidiaries and together with such Person’s heirs, executors or administrators and (ii) “Proceeding” shall mean any actual or threatened claim, action, suit, proceeding or investigation, whether civil, criminal, administrative, investigative or otherwise and whether or not such claim, action, suit, proceeding or investigation results in a formal civil or criminal litigation or regulatory action.

(b) From and after the Effective Time, solely to the extent that 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 cost or expenses (including attorneys’ fees), judgments, fines, losses, claims, damages or liabilities and amounts

37

paid in settlement in connection with any Proceeding, and 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 shall, for a period of six (6) 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, employees and agents 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 5.7(b) 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.

(c) Parent shall cause the Partnership GP to, and the Partnership GP shall, maintain in effect for six (6) years from the Effective Time the Partnership GP’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 the Partnership GP 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 the Partnership GP be required to expend pursuant to this Section 5.7(c) more than an amount per year equal to 300% of current annual premiums paid by the Partnership GP for such insurance (the “Maximum Amount”). In the event that, but for the proviso to the immediately preceding sentence, the Partnership GP would be required to expend more than the Maximum Amount, the Partnership GP shall obtain the maximum amount of such insurance as is available for the Maximum Amount. If the Partnership GP in its sole discretion elects, then, in lieu of the obligations of Parent under this Section 5.7(c), the Partnership GP may, 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; provided that in no event shall the cost of such policy exceed six (6) times the Maximum Amount.

(d) The rights of any Indemnified Person under this Section 5.7 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 5.7 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 5.7 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

38

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 5.7.

Section 5.8. 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 threaten the loss of any attorney-client privilege or other applicable legal privilege.

Section 5.9. Fees and Expenses. 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.

Section 5.10. 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 Class P Stock (including derivative securities with respect to Parent Class P 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.

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 Class P 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 Class P Stock that they receive in exchange therefor in the Merger, but that they shall receive for any such quarter either: (i) only distributions in respect of Partnership Interests or (ii) only dividends in respect of Parent Class P Stock that they receive in exchange therefor in the Merger.

Section 5.13. Coordination of Transactions. At the Closing, each of Parent and the Partnership shall coordinate the consummation of the transactions contemplated by this Agreement such that the transactions contemplated by this Agreement (including the KMR Merger Agreement and the KMP Merger Agreement) shall be consummated in the manner and sequence set forth on Section 1.2 of the Parent Disclosure Schedule.

Section 5.14. Notification of Certain Matters Regarding the KMP Merger and the KMR Merger. Parent shall give prompt notice to the other parties hereto of (a) any fact, event or circumstance known to it that is reasonably likely to, individually or taken together with all other facts, events and circumstances known to it, (i) cause or result in any condition to the closing of either the KMP Merger or KMR Merger to not be satisfied by the Outside Date or (ii) materially delay or impede the consummation of either the KMP Merger or the KMR Merger or (b) any litigation or governmental complaints, investigations or hearings, in each case to the extent such change, litigation, complaints, investigations, or hearings results in, or would reasonably be expected to materially delay or impede the consummation of either the KMP Merger or the KMR Merger.

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 intended to cause the Partnership GP to, without the consent of a majority of the then existing members of the GP Conflicts Committee, eliminate the GP Conflicts Committee, revoke or diminish the authority of the GP Conflicts Committee or remove or cause the removal of any director of the Partnership GP that is a member of the GP Conflicts Committee either as a director or as a member of such committee. For the avoidance of doubt, this Section 5.145 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 5.16. Amendments to KMP Merger Agreement and KMR Merger Agreement. At any time prior to the Effective Time, Parent may not, without the prior written consent of the GP Board, amend, modify or terminate any provision of or grant any waiver or extension under the KMP Merger Agreement or the KMR Merger, in each case, in a manner which would prevent or materially impede or delay the ability of the parties to satisfy any of the conditions to, or the consummation of, the transactions set forth in this Agreement or have an adverse effect on the value of the Merger Consideration to be received by the Partnership Unitholders in the Merger; provided, however, that following approval of the Merger and the other transactions contemplated hereunder by the Limited Partners or the stockholders of Parent, there shall be no amendment or change to the provisions of the KMP Merger Agreement or the KMR Merger Agreement which by Law or stock exchange rule would require further approval by the Limited Partners or the stockholders of Parent without such approval.

Section 5.17. 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 5.2(b), with the consent of, Parent.

Section 5.18. Performance by Parent. Subject to the terms of the KMP Agreement and the KMR Agreement, Parent shall cause its Subsidiaries to comply with the provisions of this Agreement (it being understood that with respect to KMP and its general partner and KMR and

Section 5.19. Cooperation with 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 financing, any repayment or refinancing of debt contemplated by this Agreement or required in connection with the Merger and the other 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.

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 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.
