(k) The term “Board of Directors” means the Board of Directors of the Company.

2. Indemnity of Indemnitee. Each of the MLP and the Company hereby agrees (subject to the provisions of Section 5 below) to hold harmless and indemnify Indemnitee against Expenses to the fullest extent authorized or permitted by law (including the applicable provisions of the Partnership Statute and the LLC Statute). The phrase “to the fullest extent permitted by law” shall include, but not be limited to (a) to the fullest extent permitted by any provision of the Partnership Statute and the LLC Statute that authorizes or permits additional indemnification by agreement, or the corresponding provision of any amendment to or replacement of the Partnership Statute and the LLC Statute and (b) to the fullest extent authorized or permitted by any amendments to or replacements of the Partnership Statute and the LLC Statute adopted after the date of this Agreement that increase the extent to which an entity may indemnify its officers and directors. Any amendment, alteration or repeal of the Partnership Statute and the LLC Statute that adversely affects any right of Indemnitee shall be prospective only and shall not limit or eliminate any such right with respect to any Proceeding involving any occurrence or alleged occurrence of any action or omission to act that took place prior to such amendment or repeal.

3. Additional Indemnity. Each of the MLP and the Company hereby further agrees (subject to the provisions of Section 5 below) to hold harmless and indemnify Indemnitee against Expenses incurred by reason of the fact that Indemnitee is or was a director or officer of the MLP or the Company, or is or was serving at the request of the MLP or the Company as a director, officer, trustee, employee or agent of another corporation, partnership, joint venture, trust, limited liability company or other enterprise, including, without limitation, any predecessor, subsidiary or affiliated entity of the MLP or the Company, provided that the Indemnitee shall not be indemnified and held harmless if there has been a final and non-appealable judgment entered by a court of competent jurisdiction determining that, in respect of the matter for which the Indemnitee is seeking indemnification pursuant to this Agreement, the Indemnitee acted in bad

faith or engaged in fraud or willful misconduct or, in the case of a criminal matter, acted with knowledge that the Indemnitee’s conduct was unlawful. The termination of any Proceeding by judgment, order of the court, settlement, conviction or upon a plea of nolo contendere, or its equivalent, shall not, of itself, create a presumption that Indemnitee acted in bad faith or engaged in fraud or willful misconduct or, in the case of a criminal matter, acted with knowledge that the Indemnitee’s conduct was unlawful.

4. Contribution. If the indemnification provided under Section 2 is unavailable by reason of a court decision, based on grounds other than any of those set forth in Section 5 below, then, in respect of any Proceeding in which the MLP or the Company is jointly liable with Indemnitee (or would be if joined in such Proceeding), the MLP and the Company shall contribute to the amount of Expenses actually and reasonably incurred and paid or payable by Indemnitee in such proportion as is appropriate to reflect (a) the relative benefits received by the MLP or the Company on one hand and Indemnitee on the other from the transaction from which such Proceeding arose and (b) the relative fault of the MLP or the Company on the one hand and of Indemnitee on the other in connection with the events that resulted in such Expenses as well as any other relevant equitable considerations. The relative fault of the MLP or the Company on the one hand and of Indemnitee on the other shall be determined by reference to, among other things, the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent the circumstances resulting in such Expenses. Each of the MLP and the Company agrees that it would not be just and equitable if contribution pursuant to this Section 4 were determined by pro rata allocation or any other method of allocation that does not take into account of the foregoing equitable considerations.

5. Exceptions. Any other provision herein to the contrary notwithstanding, the MLP and the Company shall not be obligated pursuant to the terms of this Agreement:

(a) Claims Initiated by Indemnitee. To indemnify or advance expenses to Indemnitee with respect to proceedings or claims initiated or brought voluntarily by Indemnitee and not by way of defense, except with respect to proceedings brought to establish or enforce a right to indemnification under this Agreement;

(b) Insured Claims. To indemnify Indemnitee for expenses or liabilities of any type whatsoever (including, but not limited to, judgments, fines, ERISA excise taxes or penalties, and amounts paid in settlement) to the extent such expenses or liabilities have been paid directly to Indemnitee by an insurance carrier under a policy of directors’ and officers’ liability insurance;

(c) Claims Under Section 16(b). To indemnify Indemnitee for expenses or the payment of profits arising from the purchase and sale by Indemnitee of securities in violation of Section 16(b) of the Securities Exchange Act of 1934, as amended, or any similar successor statute;

(d) Unlawful Claims. To indemnify Indemnitee to the extent such indemnification is prohibited by applicable law; or

(e) Unauthorized Settlement. To indemnify Indemnitee with regard to any judicial award if the MLP or the Company was not given a reasonable and timely opportunity, to participate in the defense of such action or to indemnify Indemnitee for any amounts paid in settlement of any Proceeding effected without the MLP’s or the Company’s prior written consent.

6. Choice of Counsel. If Indemnitee is a director but not an officer of the MLP or the Company, he, together with the other directors who are not officers of the MLP or the Company and are seeking indemnification (the “Outside Directors”), shall be entitled to employ, and be reimbursed for the fees and disbursements of, a single counsel separate from that chosen by Indemnitees who are officers of the MLP or the Company. The principal counsel for Outside Directors (“Principal Counsel”) shall be determined by majority vote of the Outside Directors who are seeking indemnification, and the Principal Counsel for the Indemnitees who are not Outside Directors (“Separate Counsel”) shall be determined by majority vote of such Indemnitees. The obligation of the MLP and the Company to reimburse Indemnitee for the fees and disbursements of counsel hereunder shall not extend to the fees and disbursements of any counsel employed by Indemnitee other than Principal Counsel or Separate Counsel, as the case may be, unless Indemnitee has interests that are different from those of the other Indemnitees or defenses available to him that are in addition to or different from those of the other Indemnitees such that Principal Counsel or Separate Counsel, as the case may be, would have an actual or potential conflict of interest in representing Indemnitee.

(a) Expenses (other than judgments, penalties, fines and settlements) incurred by Indemnitee shall be paid by the MLP and the Company, in advance of the final disposition of the Proceeding, within five business days after receipt of Indemnitee’s written request accompanied by substantiating documentation and Indemnitee’s written affirmation as described in subsection (c) below. No objections based on or involving the question whether such charges meet the definition of “Expenses,” including any question regarding the reasonableness of such Expenses, shall be grounds for failure to advance to such Indemnitee, or to reimburse such Indemnitee for, the amount claimed within such five business day period, and the undertaking of Indemnitee set forth in this Section 7 to repay any such amount to the extent it is ultimately determined that Indemnitee is not entitled to indemnification shall be deemed to include an undertaking to repay any such amounts determined not to have met such definition.

(b) Indemnitee hereby undertakes to repay to the MLP and the Company (i) any advances or payment of Expenses made pursuant to this Section 7 and (ii) any judgments, penalties, fines and settlements paid to or on behalf of Indemnitee hereunder, in each case to the extent that it is ultimately determined in a final judgment or other final adjudication of a court of competent jurisdiction that Indemnitee is not entitled to indemnification.

(c) As a condition to the advancement of such Expenses or the payment of such judgments, penalties, fines and settlements, Indemnitee shall execute an acknowledgment wherein Indemnitee affirms (i) that Indemnitee has met the applicable standard of conduct for

indemnification and (ii) that such Expenses or such judgments, penalties, fines and settlements, as the case may be, are delivered pursuant and are subject to the provisions of this Agreement.

8. Right of Indemnitee to Indemnification Upon Application; Procedure Upon Application. Any indemnification payment under this Agreement, other than pursuant to Section 7 hereof, shall be made no later than 30 days after receipt by the MLP and the Company of the written request of Indemnitee, accompanied by substantiating documentation, unless a determination is made within said 30-day period that Indemnitee has not met the relevant standards for indemnification set forth in Section 3 hereof by (a) the Board of Directors by a majority vote of a quorum consisting of directors who are not or were not parties to such Proceeding, (b) a committee of the Board of Directors designated by majority vote of the Board of Directors, even though less than a quorum, (c) if there are no such directors, or if such directors so direct, independent legal counsel in a written opinion or (d) the equity owners.

The right to indemnification or advances as provided by this Agreement shall be enforceable by Indemnitee in any court of competent jurisdiction. The burden of proving that indemnification is not appropriate shall be on the MLP and the Company. Neither the failure of the MLP or the Company (including its Board of Directors, any committee thereof, independent legal counsel or its equity owners) to have made a determination prior to the commencement of such action that indemnification is proper in the circumstances because Indemnitee has met the applicable standards of conduct, nor an actual determination by the MLP and the Company (including its Board of Directors, any committee thereof, independent legal counsel or its equity owners) that Indemnitee has not met such applicable standard of conduct, shall be a defense to the action or create a presumption that Indemnitee has not met the applicable standard of conduct.

9. Indemnification Hereunder Not Exclusive. The indemnification and advancement of expenses provided by this Agreement shall not be deemed exclusive of any other rights to which Indemnitee may be entitled under the MLP Partnership Agreement, the Company LLC Agreement, the Partnership Statute, the LLC Statute, any D&O Insurance maintained by or on behalf of the MLP or the Company, any agreement, or otherwise, both as to action in his official capacity and as to action in another capacity while holding such office; provided, however, that this Agreement supersedes all prior written indemnification agreements between the MLP or the Company (or any predecessor thereof) and Indemnitee with respect to the subject matter hereof. However, Indemnitee shall reimburse the MLP and the Company for amounts paid to Indemnitee pursuant to such other rights to the extent such payments duplicate any payments received pursuant to this Agreement.

10. Continuation of Indemnity. All agreements and obligations of the MLP and the Company contained herein shall continue during the period Indemnitee is a director or officer of the MLP or the Company (or is or was serving at the request of the MLP or the Company as a director, officer, employee or agent of another corporation, partnership, joint venture, trust, limited liability company or other enterprise) and shall continue thereafter so long as Indemnitee shall be subject to any possible Proceeding (notwithstanding the fact that Indemnitee has ceased to serve the MLP or the Company).

11. Partial Indemnification. If Indemnitee is entitled under any provision of this Agreement to indemnification by the MLP and the Company for a portion of Expenses, but not, however, for the total amount thereof, the MLP and the Company shall nevertheless indemnify Indemnitee for the portion of such Expenses to which Indemnitee is entitled.

12. Settlement of Claims. Neither the MLP nor the Company shall be liable to indemnify Indemnitee under this Agreement for any amounts paid in settlement of any Proceeding effected without the written consent of the MLP and the Company. Neither the MLP nor the Company shall settle any Proceeding in any manner that would impose any penalty or limitation on Indemnitee without Indemnitee’s written consent. None of the MLP, the Company or Indemnitee will unreasonably withhold their consent to any proposed settlement. Neither the MLP nor the Company shall be liable to indemnify Indemnitee under this Agreement with regard to any judicial award if the MLP and the Company were not given a reasonable and timely opportunity, at their expense, to participate in the defense of such action.

13. Acknowledgements. Each of the MLP and the Company expressly confirms and agrees that it has entered into this Agreement and assumed the obligations imposed on it hereby in order to induce Indemnitee to serve or to continue to serve as a director or officer of the MLP and/or the Company, and acknowledges that Indemnitee is relying upon this Agreement in agreeing to serve or in continuing to serve as a director or officer of the MLP and/or the Company.

14. Enforcement. In the event Indemnitee is required to bring any action or other proceeding to enforce rights or to collect moneys due under this Agreement and is successful in such action, the MLP and the Company shall reimburse Indemnitee for all of Indemnitee’s expenses in bringing and pursuing such action.

15. Severability. If any provision of this Agreement shall be held to be invalid, illegal or unenforceable (a) the validity, legality and enforceability of the remaining provisions of this Agreement shall not be in any way affected or impaired thereby, and (b) to the fullest extent possible, the provisions of this Agreement shall be construed so as to give effect to the intent manifested by the provision held invalid, illegal or unenforceable. Each section of this Agreement is a separate and independent portion of this Agreement. If the indemnification to which Indemnitee is entitled with respect to any aspect of any claim varies between two or more sections of this Agreement, that section providing the most comprehensive indemnification shall apply.

16. Liability Insurance. To the extent the MLP or the Company maintains an insurance policy or policies providing D&O Insurance, Indemnitee shall be covered by such policy or policies, in accordance with its or their terms, to the maximum extent of the coverage available and maintained by the MLP or the Company for any director or officer of the MLP or the Company or any applicable subsidiary or affiliated company.

(a) Governing Law. This Agreement and all acts and transactions pursuant hereto and the rights and obligations of the parties hereto shall be governed, construed and interpreted in accordance with the laws of the State of Delaware, without giving effect to principles of conflict of law.

(b) Entire Agreement; Enforcement of Rights. This Agreement sets forth the entire agreement and understanding of the parties relating to the subject matter herein and merges all prior discussions between them. No modification of or amendment to this Agreement, nor any waiver of any rights under this Agreement, shall be effective unless in writing signed by the parties to this Agreement. The failure by any party to enforce any rights under this Agreement shall not be construed as a waiver of any rights of such party.

(c) Construction. This Agreement is the result of negotiations between and has been reviewed by each of the parties hereto and their respective counsel, if any; accordingly, this Agreement shall be deemed to be the product of all of the parties hereto, and no ambiguity shall be construed in favor of or against any one of the parties hereto.

(d) Notices. All notices, demands or other communications to be given or delivered under or by reason of the provisions of this Agreement shall be in writing and shall be deemed to have been given (i) when delivered personally to the recipient, (ii) one business day after the date when sent to the recipient by reputable overnight courier service (charges prepaid), or (iii) five business days after the date when mailed to the recipient by certified or registered mail, return receipt requested and postage prepaid. Such notices, demands and other communications shall be sent to the parties at the addresses indicated on the signature page hereto, or to such other address as any party hereto may, from time to time, designate in writing delivered pursuant to the terms of this Section 17(d).

(e) Counterparts. This Agreement may be executed in two or more counterparts, each of which shall be deemed an original and all of which together shall constitute one instrument.

(f) Successors and Assigns. This Agreement shall be binding upon the MLP and the Company and their respective successors and assigns and shall inure to the benefit of Indemnitee and Indemnitee’s heirs, legal representatives and assigns.

(g) Subrogation. In the event of payment under this Agreement, the MLP and the Company shall be subrogated to the extent of such payment to all of the rights of recovery of Indemnitee, who shall execute all documents required and shall do all acts that may be necessary to secure such rights and to enable the MLP and the Company to effectively bring suit to enforce such rights.

IN WITNESS WHEREOF, the parties hereto have executed this Agreement on and as of the day and year first above written.
