- 14 -

Organizational Documents of Summit Investments.

(b)    The Acquiror agrees that, during the period that commences on the Closing Date and ends on the sixth (6th) anniversary of the Closing Date, it shall maintain in full force and effect and shall not cause any amendment, modification, waiver or termination to the Organizational Documents of Summit Investments, the General Partner or the Acquiror existing as of the date of this Agreement, the effect of which would be to affect adversely the rights of any person serving as a member of the board of managers or officer of Summit Investments, the General Partner or the Acquiror as of the date of this Agreement; provided, however, that the foregoing restriction shall not apply to any such amendment, modification, waiver or termination to the extent required to cause such provisions (or any portion thereof) to comply with applicable Law.

(d)    In the event that Summit Investments, the General Partner or the Acquiror or any of their respective successors or assigns (i) consolidates with or merges into any other Person and shall not be the continuing or surviving corporation or entity of such consolidation or merger or (ii) in one or more series of transactions, directly or indirectly, transfers all or substantially all of its properties and assets to any Person (whether by consolidation, merger or otherwise), then, and in each such case, proper provision shall be made so that such continuing or surviving corporation or entity or transferee of such assets or its respective successors and assigns, as the case may be, assume the obligations set forth in this Section 5.3.

Section 5.4    Intended Tax Treatment.

- 15 -

the Term Loan B and with respect to the Marmon Matter, by the Acquiror from NewCo. The Parties further agree that, for U.S. federal and applicable state and local income tax purposes, (a) the Summit Investments Purchase Price plus any liabilities under the Term Loan B or liabilities with respect to the Marmon Matter, if, when and to the extent properly treated as additional purchase price and any other amounts properly treated as consideration for the Summit Investments Interests for this purpose (including the fair market value of the NewCo Warrants and NewCo’s CODI Tax Liability, if any) shall be allocated as provided in Section 1 of Schedule 5.4, (b) the SMLP Holdings Purchase Price and any other amounts properly treated as consideration for the Subject Common Units (including the fair market value of the SMLP Holdings Warrants and SMLP Holdings’ CODI Tax Liability, if any) shall be allocated to the Subject Common Units, (c) the fair market values of the NewCo Warrants and the SMLP Holdings Warrants are set forth in Section 2 of Schedule 5.4, (d) in accordance with such allocations, the Parties intend that the Acquiror shall not incur any cancellation of debt income as a result of the Transactions, (e) no holder of a NewCo Warrant or SMLP Holdings Warrant shall be treated as a partner in Acquiror with respect to such warrant unless and until the warrant is exercised and exchanged for Common Units and (f) notwithstanding anything to the contrary herein or in the Organizational Documents of the Acquiror, (1) if and to the extent the Acquiror incurs any cancellation of debt income as a result of the Transactions, no portion of such income shall be allocated to the Sellers or any of their subsidiaries and (2) the Transactions shall not be reported for United States federal or state income tax purposes in a manner that otherwise results in cancellation of debt income to the Sellers or their subsidiaries. The Parties shall, and shall cause their Affiliates, to file all United States federal and state income Tax Returns in a manner consistent with the foregoing intended tax treatment and shall not take any position inconsistent therewith. Each of the Parties shall promptly notify the other Parties if it receives notice that any Tax Authority proposes an alternative to any portion of such treatment. With respect to any audit, examination or other proceeding by any Tax Authority against the Acquiror or any Affiliate thereof that could result in cancellation of debt income to the Sellers as a result of the Transactions, (A) the Sellers shall have the right to participate, at their expense, in such audit, examination or other proceeding (including being given the opportunity to participate in any in-person or telephonic conferences and in preparing any written submissions), and (B) the Acquiror shall not settle any portion of such audit, examination or other proceeding that could result in cancellation of debt income to the Sellers without the prior written consent of the Sellers, not to be unreasonably withheld, conditioned or delayed.

Section 5.5    Public Statements. The Parties shall consult with each other prior to issuing any public announcement, statement or other disclosure with respect to this Agreement or the other Transaction Documents or the transactions contemplated hereby or thereby and, except as required by applicable Law, including applicable regulatory authority or applicable stock exchange rules, neither the Acquiror and its respective Affiliates, on the one hand, nor the ECP Entities and their respective Affiliates, on the other hand, shall issue any such public announcement, statement or other disclosure without having first notified the Acquiror, on the one hand, or the ECP Entities, on the other hand, and provided such Party with, if legally permitted and practically possible, a reasonable time period to review and comment thereon.

Neither Party will, without the prior written consent of the other Party, take or fail to take any action that would reasonably be expected to prevent or materially impede, interfere with or delay the transactions contemplated by this Agreement. From time to time after the Closing Date, without further consideration, each Party will, at its own expense, execute and deliver such documents to the other Party as the other Party may reasonably request in order to more effectively consummate the sale and purchase of the Subject Interests hereunder.

(d)    For the period beginning on the Closing Date and ending on May 15, 2022, no ECP Party will purchase, sell or otherwise acquire or dispose of (i) any indebtedness (or instruments related thereto) of the Acquiror or any of its subsidiaries, including the Senior Notes, the Revolving Credit Agreement and Term Loan B or (ii) Series A Preferred Units or any other preferred units issued by the Acquiror.

Each Seller acknowledges, and will advise its Affiliates and its and their Representatives who receive such information, that confidential information received from the Acquiror (including pursuant to Section 5.7) may constitute material non-public information under applicable federal and state securities Laws. Notwithstanding anything contained herein to the contrary, each ECP Entity shall be permitted to disclose any information to any investor, shareholder, limited partner, member, manager, partner, officer, agent or other representative or Affiliate of such ECP Entity who (a) reasonably needs to know such information in connection with their investment in such ECP Entity or performance of services to such ECP Entity, as applicable and (b) is informed of the confidential nature of and agrees to keep confidential such information in accordance with the terms of this Section 5.9, and provided that the ECP Entities will be responsible for any breach of such terms by the recipient of the information.

INDEMNIFICATION

Section 8.1    Survival of Representations and Warranties.

(a)    Except as provided in Section 8.1(b), the representations and warranties set forth in this Agreement and in any certificate or instrument delivered in connection herewith shall terminate as of, and shall not survive, the Closing. The covenants or agreements set forth in this Agreement that, by their terms, are to be performed after Closing will survive until the expiration of the applicable statute of limitations or for such shorter period as explicitly specified herein. Notwithstanding the preceding sentences, any breach or inaccuracy of any representation or warranty or any breach of any covenant or agreement in respect of which indemnity may be sought under this Agreement shall survive the time at which it would otherwise terminate pursuant to the preceding sentences, if notice of the inaccuracy or breach thereof giving rise to such right of indemnity shall have been given to the Party against whom such indemnity may be sought prior to such time.

(b)    The Fundamental Representations shall survive the Closing until March 31, 2021. Each of the Parties acknowledges that from and after Closing it will not have any claims or causes of action or any right to indemnification pursuant to Section 8.2 or otherwise for a breach of any representation, warranty or covenant in this Agreement that does not survive the Closing.

Section 8.2    Indemnification.

(a)    From and after the Closing, subject to the terms and conditions of this Article VIII, the Sellers, jointly and severally, shall indemnify the Acquiror, its Affiliates and their respective Representatives (collectively, the “Acquiror Indemnitees”) against, shall pay or reimburse the Acquiror Indemnitees for and shall hold each of them harmless from any and all damage, loss, fines, settlement payments, awards, penalties, interest and expense (including reasonable expenses of investigation and attorneys’ fees and expenses in connection with any action, suit or proceeding involving a Third-Party Claim) (“Damages”) actually incurred or suffered by any such Acquiror Indemnitee arising out of (i) any breach of or inaccuracy in any of the Fundamental Representations of the ECP Parties and (ii) any breach of covenant or agreement made or to be performed by the ECP Parties pursuant to this Agreement.

(b)    From and after the Closing, subject to the terms and conditions of this Article VIII, Acquiror shall indemnify the Sellers, their Affiliates and their respective Representatives (collectively, the “Seller Indemnitees”) against and shall hold each of them harmless from any and all Damages actually incurred or suffered by any such Seller Indemnitee arising out of (i) any breach of or inaccuracy in any of the Fundamental Representations of Acquiror and (ii) any breach of covenant or agreement made or to be performed by the Acquiror pursuant to this Agreement.

Section 8.3    Direct Claim Procedures. If the Indemnified Party has a claim for indemnity under Section 8.2 against the Indemnifying Party that does not involve a Third-Party Claim, the Indemnified Party agrees to give prompt notice in writing of such claim to the Indemnifying Party.

- 24 -

Such notice shall set forth in reasonable detail such claim and the basis for indemnification (taking into account the information then available to the Indemnified Party). The failure to so notify the Indemnifying Party shall not relieve the Indemnifying Party of its obligations hereunder, except to the extent such failure shall have adversely prejudiced the Indemnifying Party.

Section 8.4    Third Party Claim Procedures.

(a)    The Person seeking indemnification under Section 8.2 (the “Indemnified Party”) agrees to give prompt notice in writing to the Party against whom indemnity is to be sought (the “Indemnifying Party”) of the assertion of any claim or the commencement of any suit, action or proceeding by any Third Party (“Third-Party Claim”) in respect of which indemnity may be sought under Section 8.2. Such notice shall set forth in reasonable detail such Third-Party Claim and the basis for indemnification (taking into account the information then available to the Indemnified Party). The failure to so notify the Indemnifying Party shall not relieve the Indemnifying Party of its obligations or liability hereunder, except to the extent such failure shall have actually adversely prejudiced the Indemnifying Party.

(b)    The Indemnifying Party shall be entitled to participate in the defense of any Third-Party Claim and, subject to the limitations set forth in this Section 8.4, shall be entitled to control and appoint lead counsel for such defense, in each case at its own expense; provided, that the Indemnified Party is hereby authorized, prior to the Indemnifying Party’s delivery of a written election to the Indemnified Party of its agreement to defend such Third-Party Claim, to file any motion, answer or other pleading that it shall reasonably deem necessary to protect its interests or those of the Indemnifying Party.

(c)    If the Indemnifying Party elects to assume the defense of any such Third-Party Claim, it shall within 30 days after receipt of the notice referred to in Section 8.4(a) notify the Indemnified Party in writing of its intent to do so. The Indemnifying Party will have the right to assume control of such defense of the Third-Party Claim only for so long as it conducts such defense with reasonable diligence. The Indemnifying Party shall keep the Indemnified Parties advised of the status of such Third-Party Claim and the defense thereof on a reasonably current basis and shall consider in good faith the recommendations made by the Indemnified Parties with respect thereto. If the Indemnifying Party assumes the control of the defense of any Third-Party Claim in accordance with the provisions of this Section 8.4, (i) the Indemnifying Party shall obtain the prior written consent of the Indemnified Party (which shall not be unreasonably withheld, conditioned or delayed) before entering into any settlement or compromise of such Third-Party Claim, if (A) the settlement or compromise does not release the Indemnified Party and its Affiliates from all liabilities and obligations with respect to such Third-Party Claim, (B) the settlement or compromise imposes injunctive or other equitable relief against the Indemnified Party or any of its Affiliates, or (C) the Indemnifying Party does not agree in writing to pay such amounts payable pursuant to such settlement or compromise, and (ii) the Indemnified Party shall be entitled to participate in the defense of any such Third-Party Claim and to employ, at its expense, separate counsel of its choice for such purpose; provided, that if the Indemnifying Party assumes the defense of any such Third-Party Claim but fails to diligently prosecute such claim, or if the Indemnifying Party does not assume the defense of any such claim, the Indemnified Party may assume control of such defense and the Indemnifying Party will bear the reasonable costs and expenses of such defense (including reasonable attorneys’ fees and expenses); and provided, further, that

- 25 -

notwithstanding the foregoing, the Indemnifying Party shall pay the reasonable costs and expenses of such defense (including reasonable attorneys’ fees and expenses) of the Indemnified Party if (x) the Indemnified Party’s counsel shall have reasonably concluded and advised that there are defenses available to such Indemnified Party that are different from or additional to those available to the Indemnifying Party, or (y) the Indemnified Party’s counsel shall have advised the Indemnified Party that there is a conflict of interest that could make it inappropriate under applicable standards of professional conduct to have common counsel for the Indemnifying Party and the Indemnified Party. Notwithstanding anything to the contrary in this Agreement, the Indemnifying Party will not be permitted to settle, compromise, take any corrective or remedial action or enter into an agreed judgment or consent decree, in each case, that subjects the Indemnified Party to any criminal liability, requires an admission of guilt or wrongdoing on the part of the Indemnified Party or imposes any continuing obligation on or requires any payment from the Indemnified Party without the Indemnified Party’s prior written consent, not to be unreasonably withheld, conditioned or delayed.

(d)    Each Party shall reasonably cooperate, and cause their respective controlled Affiliates to reasonably cooperate, in the defense or prosecution of any Third-Party Claim and shall furnish or cause to be furnished such records, information and testimony, and attend such conferences, discovery proceedings, hearings, trials or appeals, as may be reasonably requested in connection therewith.

Section 8.5    Limitations. Notwithstanding anything to the contrary in this Article VIII or elsewhere in this Agreement:

(a)    The Sellers shall not be required to pay any Damages to any Acquiror Indemnitees pursuant to Section 8.2(a) prior to the time that the principal amounts have been repaid by the Acquiror under the NewCo Loan Agreement and the SMLP Holdings Loan Agreement, and thereafter any such payments shall not exceed the lesser of (i) the aggregate principal amount repaid by the Acquiror under the NewCo Loan Agreement and the SMLP Holdings Loan Agreement and (ii) the Purchase Price.

(b)    Each Indemnified Party shall take, and cause its Affiliates to take, commercially reasonable steps to mitigate any Damages for which it would otherwise be entitled to indemnification pursuant to this Article VIII upon becoming aware of any event or circumstance that would be reasonably expected to, or does, give rise thereto, including incurring costs only to the minimum extent necessary to remedy the breach that gives rise to such Damages.

(c)    If, prior to the Closing, with respect to any Party (the “Waiving Party”), (i) its Designated Officer has actual knowledge of any breach (and not a mere awareness of a set of circumstances which later manifests itself as a breach) by any other Party of any representation, warranty, covenant or agreement contained in this Agreement or (ii) its Designated Officer has, as a result of a failure during the Interim Period to exercise reasonably prudent diligence and care in accordance with past practices, directly caused any breach by any other Party of any representation, warranty, covenant or agreement contained in this Agreement (provided that any action taken by a Designated Officer of a Summit Entity on the instruction of the board of directors or board of managers of a Summit Entity shall not be deemed to have caused a breach for the purposes of this sub-paragraph (ii)), and, in either case, the Waiving Party proceeds with the Closing, then the Waiving Party shall be deemed to have waived such breach and the Waiving Party and the other

- 26 -

Acquiror Indemnitees or the Seller Indemnitees, as applicable, shall not be entitled to indemnification pursuant to this Article VIII or to sue for damages under this Agreement relating to such breach, notwithstanding anything to the contrary contained herein or in any certificate delivered pursuant hereto.

(d)    NOTWITHSTANDING ANYTHING TO THE CONTRARY IN THIS AGREEMENT, NEITHER THE ACQUIROR NOR THE SELLERS NOR THEIR RESPECTIVE AFFILIATES SHALL BE LIABLE HEREUNDER TO ANY INDEMNIFIED PARTY FOR ANY LOST PROFITS OR PUNITIVE, CONSEQUENTIAL, REMOTE, SPECULATIVE, SPECIAL OR INDIRECT DAMAGES, EXCEPT TO THE EXTENT SUCH LOST PROFITS OR DAMAGES ARE INCLUDED IN ANY ACTION BY A THIRD PARTY AGAINST SUCH INDEMNIFIED PARTY FOR WHICH IT IS ENTITLED TO INDEMNIFICATION UNDER THIS AGREEMENT.

Further, the Acquiror and Summit Investments agree that, in the event that a dispute arises after Closing between the Acquiror or

- 31 -

Summit Investments and any ECP Entity or any of their respective Affiliates, L&W may represent such ECP Entity or Affiliate in such dispute even though the interests of such ECP Entity or Affiliate may be directly adverse to the Acquiror or Summit Investments.

(c)    The Acquiror acknowledges that any advice given to or communication with any ECP Entity or any of their respective Affiliates (other than Summit Investments) shall not be subject to any joint privilege and shall be owned solely by such ECP Entities or Affiliate. The Acquiror and Summit Investments each hereby acknowledge that each of them have had the opportunity to discuss and obtain adequate information concerning the significance and material risks of, and reasonable available alternatives to, the waivers, permissions and other provisions of this Agreement, including the opportunity to consult with counsel other than L&W.

(b)    The Borrower shall apply (i) all Material Debt-Related Net Proceeds received by the MLP Entity, SMPH, SMP, the Borrower or any Affiliate or Subsidiary of the Borrower and (ii) all Net Proceeds which, in the aggregate, are in excess of $125.0 million, received by the MLP Entity, SMPH, SMP, the Borrower or any Affiliate or Subsidiary of the Borrower in connection with (x) the incurrence of Indebtedness pursuant to Section 6.01(j) and (y) any disposition made pursuant to Section 6.05(j), in each case, promptly upon (and in any event within three Business Days of) receipt thereof to prepay any outstanding Loan in accordance with paragraphs (b) and (c) of Section 2.03; provided that the Borrower may use a ratable portion of such Material Debt-Related Net Proceeds or Net Proceeds, as applicable, to prepay Indebtedness outstanding under the SMLP Holdings Credit Agreement (with such prepaid Indebtedness permanently extinguished), in an amount not to exceed the product of (y) the amount of such

40

Material Debt-Related Net Proceeds or Net Proceeds, as applicable, multiplied by (z) a fraction, the numerator of which is the outstanding principal amount of Indebtedness under the SMLP Holdings Credit Agreement and the denominator of which is the sum of the outstanding principal amount of Indebtedness under the SMLP Holdings Credit Agreement and the outstanding principal amount of Loans hereunder.

(c)    The Borrower shall notify the Administrative Agent in writing of any mandatory prepayment of Loans required to be made by the Borrower pursuant to paragraph (b) of this Section 2.04 at least three Business Days prior to the date of such prepayment. Each such notice shall specify the date of such prepayment and provide a reasonably detailed calculation of the amount of such prepayment. The Administrative Agent will promptly notify each Lender of the contents of the Borrower’s prepayment notice and of such Lender’s pro rata share of the prepayment.

Section 2.05    Fees. [All Fees shall be paid on the dates due, in immediately available funds, to the Administrative Agent for distribution, if and as appropriate, among the Lenders. Once paid, none of the Fees shall be refundable under any circumstances.]⁵

Section 2.06    Interest. (a) The Borrower shall pay interest on the unpaid principal amount of each Loan at the rate of 8.00% per annum.

(b)    Notwithstanding the foregoing, if any principal of or interest on any Loan or any Fees or other amount payable by the Borrower hereunder is not paid when due, whether at stated maturity, upon acceleration or otherwise, the Borrower shall pay interest on such overdue amount, after as well as before judgment, at a rate equal to 12.00% per annum plus the rate applicable to such Loans as provided in paragraph (a) of this Section; provided, that this paragraph (b) shall not apply to any Default or Event of Default that has been waived by the Lenders pursuant to Section 9.08.

(c)    Accrued interest on each Loan shall be payable in kind by the Borrower in arrears on the last day of each calendar quarter by adding the amount thereof to the outstanding principal amount of the Loans owed to the applicable Lenders, and such increased principal amount shall thereafter bear interest at the rate per annum set forth in paragraphs (a) and (b) of this Section, as applicable, and be paid in accordance with Sections 2.02, 2.03 and 2.04; provided, that, at the option of the Administrative Agent, interest accrued pursuant to paragraph (b) of this Section shall be payable on demand.

(d)    All computations of interest shall be made by the Administrative Agent taking into account the actual number of days occurring in the period for which such interest is payable pursuant to this Section, and on the basis of a year of 360 days.

Section 2.07    Taxes. (a) Any and all payments by or on account of any obligation of any Loan Party under any Loan Document shall be made free and clear of and without deduction for any Taxes, except to the extent such withholding or deduction is required by applicable law. If a

41

Loan Party, the Administrative Agent or any other Person acting on behalf of the Administrative Agent in regards to payments hereunder shall be required to deduct Indemnified Taxes or Other Taxes from such payments by applicable law, then (i) the sum payable by the Loan Party shall be increased as necessary so that after making all required deductions for Indemnified Taxes and Other Taxes (including deductions applicable to additional sums payable under this Section) the Administrative Agent or Lender, as applicable, receives an amount equal to the sum it would have received had no such deductions for Indemnified Taxes and Other Taxes been made, (ii) such Loan Party, Administrative Agent or other Person acting on behalf of the Administrative Agent shall make such deductions and (iii) such Loan Party, Administrative Agent or other Person acting on behalf of the Administrative Agent shall timely pay the full amount deducted to the relevant Governmental Authority in accordance with applicable law. For purposes of this Section 2.07, if a Lender is treated as a domestic partnership for U.S. federal income tax purposes any withholding or payment of a U.S. federal withholding tax by such Lender or by any direct or indirect member of such Lender that is a domestic partnership or withholding foreign partnership for U.S. federal income tax purposes, with respect to any payments made by or on behalf of any Loan Party under this Agreement or any other Loan Document, shall be considered a withholding or deduction of such U.S. federal withholding tax by Borrower.

If a payment made to a Lender under this Agreement would be subject to U.S. federal withholding tax imposed by FATCA if such Lender were to fail to comply with the applicable reporting requirements of FATCA (including those contained in Section 1471(b) or 1472(b) of the Code, as applicable), such Lender shall deliver to the Borrower and Administrative Agent, at the time or times prescribed by law and at such time or times reasonably requested by the Borrower or Administrative Agent, such documentation prescribed by applicable law (including as prescribed by Section 1471(b)(3)(C)(i) of the Code) and such additional documentation reasonably requested by the Borrower or Administrative Agent as may be necessary for the Borrower or Administrative Agent to comply with its obligations under FATCA, to determine that such Lender has complied with such Lender’s obligations under FATCA or to determine the amount to deduct and withhold from such payment. Solely for purposes of this paragraph, FATCA shall include any amendments to FATCA made after the Closing Date.

(b)    In addition, each Loan Party shall pay any Other Taxes payable on account of any obligation of such Loan Party and upon the execution, delivery or enforcement of, or otherwise with respect to, the Loan Documents, to the relevant Governmental Authority in accordance with applicable law.

(c)    Each Loan Party shall indemnify the Administrative Agent and each Lender, within 30 days after written demand therefor, for the full amount of any Indemnified Taxes or Other Taxes (other than Indemnified Taxes or Other Taxes resulting from gross negligence or willful misconduct of the Administrative Agent or such Lender as determined in the final, nonappealable judgment of a court of competent jurisdiction) without duplication of any amounts indemnified under Section 2.07(a)) imposed or assessed on (and whether or not paid directly by) the Administrative Agent or such Lender, as applicable, with respect to any payment by or on account of any obligation of such Loan Party under, or otherwise with respect to, any Loan Document (including Indemnified Taxes or Other Taxes imposed or asserted on or attributable to amounts payable under this Section) and any reasonable expenses arising therefrom or with respect thereto, whether or not such Indemnified Taxes or Other Taxes were correctly or legally imposed

42

or asserted by the relevant Governmental Authority; provided, that a certificate as to the amount of such payment, liability, imposition or assessment and setting forth in reasonable detail the basis and calculation for such payment or liability delivered to such Loan Party by a Lender, or by the Administrative Agent on its own behalf or on behalf of a Lender, shall be conclusive absent manifest error of the Lender or the Administrative Agent, as applicable.

(d)    As soon as practicable after any payment of Indemnified Taxes or Other Taxes by a Loan Party to a Governmental Authority such Loan Party shall deliver to the Administrative Agent the original or a certified copy of a receipt issued by such Governmental Authority evidencing such payment, a copy of the return reporting such payment or other evidence of such payment reasonably satisfactory to the Administrative Agent.

(e)    Each Lender that is not a “United States Person” as defined in Section 7701(a)(30) of the Code (a “Non-U.S. Lender”) shall, to the extent it may lawfully do so, deliver to the Borrower and the Administrative Agent two copies of U.S. Internal Revenue Service Form W-8BEN (claiming the benefits of an applicable income tax treaty), W-8EXP, W-8IMY (together with any required attachments) or Form W-8ECI, or, in the case of a Non-U.S. Lender claiming exemption from U.S. federal withholding tax under Section 871(h) or 881(c) of the Code with respect to payments of “portfolio interest,” a statement substantially in the form of Exhibit D and a Form W-8BEN, or any subsequent versions thereof or successors thereto, properly completed and duly executed by such Non-U.S. Lender (with any other required forms attached) claiming complete exemption from or a reduced rate of U.S. federal withholding tax on all payments by or on behalf of the Borrower under this Agreement and the other Loan Documents. Each Lender that is not a Non-U.S. Lender shall, to the extent it may lawfully do so, deliver to the Borrower and the Administrative Agent two copies of U.S. Internal Revenue Service Form W-9, properly completed and duly executed by such Lender, claiming complete exemption (or otherwise establishing an exemption) from U.S. backup withholding on all payments under this Agreement and the other Loan Documents. Such forms shall be delivered by each Lender, to the extent it may lawfully do so, on or before the date it becomes a party to this Agreement (or, in the case of any Participant, on or before the date such Participant purchases the related participation). In addition, each Lender, to the extent it may lawfully do so, shall deliver such forms promptly upon the obsolescence or invalidity of any form previously delivered by such Lender. Each Lender shall promptly notify the Borrower and the Administrative Agent at any time it determines that it is no longer in a position to provide any previously delivered certificate to the Borrower or the Administrative Agent (or any other form of certification adopted by the U.S. taxing authorities for such purpose). Without limiting the foregoing, any Lender that is entitled to an exemption from or reduction of withholding Tax otherwise indemnified against by a Loan Party pursuant to this Section 2.07 with respect to payments under any Loan Document shall deliver to the Borrower or the relevant Governmental Authority (with a copy to the Administrative Agent), to the extent such Lender is legally entitled to do so, at the time or times prescribed by applicable law such properly completed and executed documentation prescribed by applicable law as may reasonably be requested by the Borrower or the Administrative Agent to permit such payments to be made without such withholding tax or at a reduced rate; provided, that in such Lender’s judgment such completion, execution or submission would not materially prejudice such Lender.

(f)    [The Administrative Agent shall deliver to the Borrower, on or before the Closing Date, two duly completed copies of Internal Revenue Service Form W-8IMY certifying

43

that it is a “U.S. branch” and that the payments it receives for the account of others are not effectively connected with the conduct of its trade or business in the United States and that it is using such form as evidence of its agreement with the Borrower to be treated as a United States person with respect to such payments (and the Borrower and the Administrative Agent agree to so treat the Administrative Agent as a United States person with respect to such payments), with the effect that the Borrower can make payments to the Administrative Agent without deduction or withholding of any Taxes imposed by the United States.]⁶

(g)    If the Administrative Agent or any Lender determines, in good faith and in its sole discretion, that it has received a refund of Indemnified Taxes or Other Taxes as to which it has been indemnified by a Loan Party or with respect to which a Loan Party has paid additional amounts pursuant to this Section 2.07, it shall pay over such refund to such Loan Party (but only to the extent of indemnity payments made, or additional amounts paid, by such Loan Party under this Section 2.07 with respect to the Indemnified Taxes or Other Taxes giving rise to such refund), net of all out-of-pocket expenses of the Administrative Agent or Lender (including any Taxes imposed with respect to such refund) as is determined by the Administrative Agent or Lender in good faith and in its sole discretion, and without interest (other than any interest paid by the relevant Governmental Authority with respect to such refund); provided, that such Loan Party, upon the request of the Administrative Agent or Lender agrees to repay as soon as reasonably practicable the amount paid over to such Loan Party (plus any penalties, interest or other charges imposed by the relevant Governmental Authority) to the Administrative Agent or Lender in the event such Administrative Agent or Lender is required to repay such refund to such Governmental Authority. This paragraph shall not be construed to require the Administrative Agent or Lender to make available its Tax returns (or any other information relating to its Taxes which it deems confidential) to the Loan Parties or any other Person.

Section 2.08    Payments Generally; Pro Rata Treatment; Sharing of Set-offs. (a) Unless otherwise specified, the Borrower shall make each payment required to be made by it hereunder (whether of principal, interest or fees, or of amounts payable under Section 2.07 or otherwise) prior to 2:00 p.m., New York City time, on the date when due, in immediately available funds, without condition or deduction for any defense, recoupment, set-off or counterclaim. Any amounts received after such time on any date may, in the discretion of the Administrative Agent, be deemed to have been received on the next succeeding Business Day for purposes of calculating interest thereon. All such payments shall be made to the Administrative Agent to the applicable account designated to the Borrower by the Administrative Agent, except that payments pursuant to Sections 2.07 and 9.05 shall be made directly to the Persons entitled thereto. The Administrative Agent shall distribute any such payments received by it for the account of any other Person to the appropriate recipient promptly following receipt thereof. If any payment hereunder shall be due on a day that is not a Business Day, the date for payment shall be extended to the next succeeding Business Day, and, in the case of any payment accruing interest, interest thereon shall be payable for the period of such extension. All payments hereunder of principal or interest in respect of any Loan shall be made in U.S. Dollars. All payments of other amounts due hereunder or under any other Loan Document shall be made in U.S. Dollars. Any payment required to be made by the Administrative Agent hereunder shall be deemed to have been made by the time required if the

44

Administrative Agent shall, at or before such time, have taken the necessary steps to make such payment in accordance with the regulations or operating procedures of the clearing or settlement system used by the Administrative Agent to make such payment.

(b)    If at any time insufficient funds are received by and available to the Administrative Agent from the Borrower to pay fully all amounts of principal, interest, fees and other amounts then due from the Borrower hereunder, such funds shall be applied first, to Administrative Agent’s fees and reimbursable expenses then due and payable pursuant to any of the Loan Documents; second, to all reimbursable expenses of the Lenders then due and payable pursuant to any of the Loan Documents, ratably among the Lenders in proportion to the respective amounts of such fees and expenses payable to them; third, to interest and fees then due and payable hereunder, ratably among the Lenders in proportion to the respective amounts of such interest and fees payable to them; and fourth, to the principal balance of the Loans, until the same shall have been paid in full, ratably among the Lenders in proportion to such Lender’s Percentage.

(c)    If any Lender shall, by exercising any right of set-off or counterclaim, through the application of any proceeds of Collateral or otherwise, obtain payment in respect of any principal of or interest on any of its Loans resulting in such Lender receiving payment of a greater proportion of the aggregate amount of its Loans and accrued interest thereon than the proportion received by any other Lender, then the Lender receiving such greater proportion shall purchase (for cash at face value) participations in Loans of other Lenders to the extent necessary so that the benefit of all such payments shall be shared by the Lenders ratably in accordance with the aggregate amount of principal of and accrued interest on their respective Loans; provided, that (i) if any such participations are purchased and all or any portion of the payment giving rise thereto is recovered, such participations shall be rescinded and the purchase price restored to the extent of such recovery, without interest, and (ii) the provisions of this paragraph (c) shall not be construed to apply to any payment made by the Borrower pursuant to and in accordance with the express terms of this Agreement or any payment obtained by a Lender as consideration for the assignment of or sale of a participation in any of its Loans to any assignee or participant, other than to the Borrower or any Restricted Subsidiary (as to which the provisions of this paragraph (c) shall apply). The Borrower consents to the foregoing and agrees, to the extent it may effectively do so under applicable law, that any Lender acquiring a participation pursuant to the foregoing arrangements may exercise against the Borrower rights of set-off and counterclaim with respect to such participation as fully as if such Lender were a direct creditor of the Borrower in the amount of such participation.

(d)    Unless the Administrative Agent shall have received notice from the Borrower prior to the date on which any payment by the Borrower is due to the Administrative Agent for the account of the Lenders hereunder that the Borrower will not make such payment, the Administrative Agent may assume that the Borrower has made such payment on such date in accordance herewith and may, in reliance upon such assumption, distribute to the Lenders, as applicable, the amount due. In such event, if the Borrower has not in fact made such payment, then each of the Lenders, as applicable, severally agrees to repay to the Administrative Agent forthwith on demand the amount so distributed to such Lender with interest thereon, for each day from and including the date such amount is distributed to it to but excluding the date of payment to the Administrative Agent, at the greater of the Federal Funds Effective Rate and a rate determined by the Administrative Agent in accordance with banking industry rules on interbank compensation.

45

(e)    If any Lender shall fail to make any payment required to be made by it pursuant to Section 2.08(d), then the Administrative Agent may, in its discretion (notwithstanding any contrary provision hereof), apply any amounts thereafter received by the Administrative Agent for the account of such Lender to satisfy such Lender’s obligations under such Sections until all such unsatisfied obligations are fully paid.

(f)    None of the funds or assets of the Borrower that are used to pay any amount due pursuant to this Agreement shall constitute, to the Borrower’s knowledge, funds obtained from transactions with or relating to Anti-Corruption Laws or Sanctions.

Section 3.15    Foreign Corrupt Practices, Sanctions. None of the Borrower nor any of its Subsidiaries, nor any director, officer, agent or employee of any such the Borrower or any of its Subsidiaries is aware of or has taken any action, directly or indirectly, that would result in a material violation by such Persons of the FCPA or any other Anti-Corruption Laws, including without limitation, making use of the mails or any means or instrumentality of interstate commerce corruptly in furtherance of an offer, payment, promise to pay or authorization of the payment of any money, or other Property, gift, promise to give, or authorization of the giving of anything of value to any “foreign official” (as such term is defined in the FCPA) or any foreign political party or official thereof or any candidate for foreign political office, in contravention of the FCPA, and the Borrower and its Subsidiaries have conducted their business in material compliance with the FCPA.

THE AGENTS

Section 8.01    Appointment and Authority. (a) Each of the Lenders hereby irrevocably appoints [ ] to act on its behalf as the Administrative Agent hereunder and under the other Loan Documents and authorizes the Administrative Agent to take such actions on its behalf and to exercise such powers as are delegated to the Administrative Agent by the terms hereof or thereof, together with such actions and powers as are reasonably incidental thereto.

In this connection, the Collateral Agent and any co-agents, sub-agents and attorneys-in-fact appointed by the Collateral Agent pursuant to Section 8.05 or Section 8.11 for purposes of holding or enforcing any Lien on the Collateral (or any portion thereof) granted under the Collateral Documents, or for exercising any rights and remedies thereunder at the direction of the Administrative Agent, shall be entitled to the benefits of all provisions of this Article VIII (including Section 8.10) and Article IX as though such co-agents, sub-agents and attorneys-in-fact were the Collateral Agent under the Loan Documents.

(c)    The provisions of this Article are solely for the benefit of the Administrative Agent, the Collateral Agent, any co-agents, sub-agents, attorneys-in-fact or other appointees thereof and the Lenders, and none of the MLP Entity, the Borrower nor any Subsidiary of the Borrower shall have rights as a third party beneficiary of any of such provisions.

Section 8.02    Rights as a Lender. Any Person serving as an Agent hereunder shall have the same rights and powers in its capacity as a Lender as any other Lender, and may exercise the same as though it were not an Agent, and the term “Lender” or “Lenders” shall, unless otherwise expressly indicated or unless the context otherwise requires, include a Person serving as an Agent hereunder in its individual capacity. Such Person and its Affiliates may accept deposits from, lend money to, act as the financial advisor or in any other advisory capacity for and generally engage in any kind of business with the Borrower or any Subsidiary or other Affiliate thereof as if such Person were not an Agent hereunder and without any duty to account therefor to the Lenders.

Section 8.03    Exculpatory Provisions. No Agent shall have any duties or obligations except those expressly set forth herein and in the other Loan Documents, and its duties hereunder shall be administrative in nature. Without limiting the generality of the foregoing, no Agent:

(b)    shall have any duty to take any discretionary action or exercise any discretionary powers, except discretionary rights and powers expressly contemplated hereby or by the other Loan Documents that such Agent is required to exercise as directed in writing by the Required Lenders (or such other number or percentage of the Lenders as shall be expressly

86

provided for herein or in the other Loan Documents); provided, that no Agent shall be required to take any action that, in its opinion or the opinion of its counsel, may expose such Agent to liability or that is contrary to any Loan Document or applicable law;

(c)    shall, except as expressly set forth herein and in the other Loan Documents, have any duty to disclose, and shall not be liable for the failure to disclose, any information relating to the Borrower or any of its Affiliates that is communicated to or obtained by the Person serving as such Agent or any of its Affiliates in any capacity;

(d)    shall be liable for any action taken or not taken by it (i) with the consent or at the request of the Required Lenders (or such other number or percentage of the Lenders as shall be necessary, or as such Agent shall believe in good faith shall be necessary, under the circumstances as provided in Sections 9.08 and 7.01) or (ii) in the absence of its own gross negligence or willful misconduct as determined by a court of competent jurisdiction by final and non-appealable judgment;

(e)    shall be responsible for or have any duty to ascertain or inquire into (i) any statement, warranty or representation made in or in connection with this Agreement or any other Loan Document, (ii) the contents of any certificate, report or other document delivered hereunder or thereunder or in connection herewith or therewith, (iii) the performance or observance of any of the covenants, agreements or other terms or conditions set forth herein or therein or the occurrence of any Default, (iv) the validity, enforceability, effectiveness or genuineness of this Agreement, any other Loan Document or any other agreement, instrument or document, or the creation, perfection or priority of any Lien purported to be created by the Collateral Documents, (v) the value or the sufficiency of any Collateral, or (v) the satisfaction of any condition set forth in Article IV or elsewhere herein, other than to confirm receipt of items expressly required to be delivered to such Agent; and

(f)    shall be deemed to have knowledge of any Default or Event of Default unless and until written notice describing such Default or Event of Default is received by such Agent from the Borrower or a Lender.

Section 8.04    Reliance by Agents. Any Agent shall be entitled to rely upon, and shall not incur any liability for relying upon, any notice, request, certificate, consent, statement, instrument, document or other writing (including any electronic message, Internet or intranet website posting or other distribution) believed by it to be genuine and to have been signed, sent or otherwise authenticated by an appropriate Person. Any Agent also may rely upon any statement made to it orally or by telephone and believed by it to have been made by an appropriate Person, and shall not incur any liability for relying thereon. In determining compliance with any condition hereunder to the making of a Loan that by its terms must be fulfilled to the satisfaction of a Lender, any Agent may presume that such condition is satisfactory to such Lender unless such Agent shall have received notice to the contrary from such Lender prior to the making of such Loan. Any Agent may consult with legal counsel (who may include counsel for the Borrower), independent accountants and other experts selected by it, and shall not be liable for any action taken or not taken by it in accordance with the advice of any such counsel, accountants or experts.

87

Section 8.05    Delegation of Duties. Without in any way limiting Section 8.11, any Agent may perform any and all of its duties and exercise its rights and powers hereunder or under any other Loan Document by or through any one or more co-agents, sub-agents and/or attorneys-in-fact appointed by such Agent. Any Agent and any such co-agents, sub-agents and/or attorneys-in-fact may perform any and all of its duties and exercise its rights and powers by or through their respective Related Parties. The exculpatory provisions of this Article shall apply to any such co-agents, sub-agents and/or attorneys-in-fact and to the Related Parties of each Agent and any such co-agents, sub-agents and/or attorneys-in-fact, and shall apply to their respective activities in connection with the syndication of the credit facilities provided for herein as well as activities as an Agent.

Section 8.06    Resignation of the Agents. Any Agent may at any time give notice of its resignation to the Lenders and the Borrower. Upon receipt of any such notice of resignation, the Required Lenders shall have the right to appoint a successor with the consent of the Borrower (not to be unreasonably withheld or delayed), which shall be a financial institution with an office in the United States, or an Affiliate of any such financial institution with an office in the United States, and having a combined capital and surplus of at least U.S.$1.0 billion. In the case of the resignation of an Agent, if no such successor shall have been appointed by the Required Lenders and the Borrower and shall have accepted such appointment within 30 days after the retiring Agent gives notice of its resignation, then such resignation shall nonetheless become effective in accordance with such notice and (a) the retiring Agent shall be discharged from its duties and obligations hereunder and under the other Loan Documents (except that in the case of any collateral security held by the Collateral Agent on behalf of the Secured Parties under any of the Loan Documents, the retiring Collateral Agent shall continue to hold such collateral security, as bailee, until such time as a successor Collateral Agent is appointed), (b) except for indemnity payments owed to the retiring Administrative Agent, all payments, communications and determinations provided to be made by, to or through the Administrative Agent shall instead be made by or to each Lender directly, until such time as the Required Lenders and the Borrower appoint a successor Administrative Agent as provided for above in this Section and (c) the Borrower and the Lenders agree that in no event shall the retiring Agent or any of its Affiliates or any of their respective officers, directors, employees, agents advisors or representatives have any liability to the MLP Entity, the Borrower or any Subsidiary, any Lender or any other Person or entity for damages of any kind, including, without limitation, direct or indirect, special, incidental or consequential damages, losses or expenses (whether in tort, contract or otherwise) arising out of the failure of a successor Agent to be appointed and to accept such appointment. Upon the acceptance of a successor’s appointment as Agent hereunder, such successor shall succeed to and become vested with all of the rights, powers, privileges and duties of the retiring or retired Agent (other than any rights to indemnity payments owed to the retiring Agent), and the retiring or retired Agent shall be discharged from all of its duties and obligations hereunder and under the other Loan Documents (if not already discharged therefrom as provided above in this Section). The fees payable by the Borrower to a successor Agent shall be the same as those payable to its predecessor unless otherwise agreed between the Borrower and such successor. After the retiring Agent’s resignation hereunder and under the other Loan Documents, the provisions of this Article (including Section 8.10) and Section 9.05 shall continue in effect for the benefit of such retiring Agent, its sub-agents and their respective Related Parties in respect of any actions taken or omitted to be taken by any of them while the retiring Agent was acting as Agent.

88

Section 8.07    Non-Reliance on the Agents; Other Lenders. Each Lender acknowledges that it has, independently and without reliance upon any Agent or any other Lender or any of their Related Parties and based on such documents and information as it has deemed appropriate, made its own credit analysis and decision to enter into this Agreement. Each Lender also acknowledges that it will, independently and without reliance upon any Agent or any other Lender or any of their Related Parties and based on such documents and information as it shall from time to time deem appropriate, continue to make its own decisions in taking or not taking action under or based upon this Agreement, any other Loan Document or any related agreement or any document furnished hereunder or thereunder.

Section 8.08    Administrative Agent May File Proofs of Claim. In case of the pendency of any proceeding under any federal, state or foreign bankruptcy, insolvency, receivership or similar law or any other judicial proceeding relative to the MLP Entity, the Borrower or any Restricted Subsidiary, the Administrative Agent (irrespective of whether the principal of any Loan shall then be due and payable as herein expressed or by declaration or otherwise and irrespective of whether the Administrative Agent shall have made any demand on the Borrower or any other Loan Party) shall be entitled and empowered (but not obligated), by intervention in such proceeding or otherwise:

(a)    to file and prove a claim for the whole amount of the principal and interest owing and unpaid in respect of the Loans and all other Obligations that are owing and unpaid and to file such other documents as may be necessary or advisable in order to have the claims of the Lenders and the Administrative Agent (including any claim for the reasonable compensation, expenses, disbursements and advances of the Lenders and the Administrative Agent and their respective agents and counsel and all other amounts due the Lenders and the Administrative Agent under Sections 2.05, 8.10, and 9.05) allowed in such judicial proceeding; and

(b)    to collect and receive any monies or other property payable or deliverable on any such claims and to distribute the same;

and any custodian, receiver, assignee, trustee, liquidator, sequestrator or other similar official in any such judicial proceeding is hereby authorized by each Lender to make such payments to the Administrative Agent and, if the Administrative Agent shall consent to the making of such payments directly to the Lenders, to pay to the Administrative Agent any amount due for the reasonable compensation, expenses, disbursements and advances of the Administrative Agent and its agents and counsel, and any other amounts due the Administrative Agent under Sections 2.05, 8.10 and 9.05.

Nothing contained herein shall be deemed to authorize the Administrative Agent to authorize or consent to or accept or adopt on behalf of any Lender any plan of reorganization, arrangement, adjustment or composition affecting the Obligations or the rights of any Lender to authorize the Administrative Agent to vote in respect of the claim of any Lender in any such proceeding and to subordinate any Lien on any Property granted to or held by the Administrative Agent under any Loan Document to the holder of any Permitted Lien.

Section 8.09    Authorization for Certain Releases. With respect to releases and terminations delivered pursuant to Section 9.18, each Agent, each Lender, hereby irrevocably

89

authorizes either or both Agents to enter into such releases and terminations without further or additional consents being delivered by any Agent or any Lender. Upon request by the Administrative Agent or the Collateral Agent at any time, the Required Lenders will confirm in writing each Agent’s authority provided for in the previous sentence.

Section 8.10    Indemnification. Each Lender severally agrees (i) to reimburse each Agent, on demand, in the amount of its pro rata share (in accordance with the respective principal amounts of its applicable outstanding Loans)) of any reasonable expenses incurred for the benefit of the Lenders by such Agent, including reasonable counsel fees and compensation of agents and employees paid for services rendered on behalf of the Lenders, which shall not have been reimbursed by the Borrower and (ii) to indemnify and hold harmless each Agent and any of its directors, officers, employees or agents, on demand, in the amount of such pro rata share, from and against any and all liabilities, Taxes, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind or nature whatsoever which may be imposed on, incurred by or asserted against such Agent in its capacity as Administrative Agent or Collateral Agent, as applicable, or any of them in any way relating to or arising out of this Agreement or any other Loan Document or any action taken or omitted by it or any of them under this Agreement or any other Loan Document, to the extent the same shall not have been reimbursed by the Borrower; provided, that no Lender shall be liable to any Agent for any portion of such liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements to the extent found in a final nonappealable judgment by a court of competent jurisdiction to have resulted from the gross negligence or willful misconduct of such Agent or any of its directors, officers, employees or agents.

Section 8.11    Appointment of Supplemental Collateral Agents. (a) This Section 8.11 shall not in any way limit Section 8.05. It is the purpose of this Agreement and the other Loan Documents that there shall be no violation of any law of any jurisdiction denying or restricting the right of banking corporations or associations or other institutions to transact business as agent or trustee in such jurisdiction. It is recognized that in case of litigation under this Agreement or any of the other Loan Documents, and in particular in case of the enforcement of any of the Loan Documents, or in case the Collateral Agent deems that by reason of any present or future law of any jurisdiction it may not exercise any of the rights, powers or remedies granted herein or in any of the other Loan Documents or take any other action which may be desirable or necessary in connection therewith, it may be necessary that the Collateral Agent appoint an additional institution as a separate trustee, co-trustee, collateral agent, collateral sub-agent or collateral co-agent (any such additional individual or institution being referred to herein individually as a “Supplemental Collateral Agent” and collectively as “Supplemental Collateral Agents”).

(b)    In the event that the Collateral Agent appoints a Supplemental Collateral Agent with respect to any Collateral, (i) each and every right, power, privilege or duty expressed or intended by this Agreement or any of the other Loan Documents to be exercised by or vested in or conveyed to the Collateral Agent with respect to such Collateral shall be exercisable by and vest in such Supplemental Collateral Agent to the extent, and only to the extent, necessary to enable such Supplemental Collateral Agent to exercise such rights, powers and privileges with respect to such Collateral and to perform such duties with respect to such Collateral, and every covenant and obligation contained in the Loan Documents and necessary to the exercise or performance thereof by such Supplemental Collateral Agent shall run to and be enforceable by either or both the

90

Collateral Agent and/or such Supplemental Collateral Agent, and (ii) the provisions of this Article and of Section 9.05 that refer to the Administrative Agent, the Collateral Agent or the Agents shall inure to the benefit of such Supplemental Collateral Agent and all references therein to the Administrative Agent, the Collateral Agent or the Agents shall be deemed to be references to the Administrative Agent, the Collateral Agent or the Agents and/or such Supplemental Collateral Agent, as the context may require.

(c)    Should any instrument in writing from any Loan Party be required by any Supplemental Collateral Agent so appointed by the Collateral Agent for more fully and certainly vesting in and confirming to it such rights, powers, privileges and duties, such Loan Party shall execute, acknowledge and deliver any and all such instruments promptly upon request by the Collateral Agent. In case any Supplemental Collateral Agent, or a successor thereto, shall die, become incapable of acting, resign or be removed, all the rights, powers, privileges and duties of such Supplemental Collateral Agent, to the extent permitted by law, shall vest in and be exercised by the Collateral Agent until the appointment of a new Supplemental Collateral Agent.

Section 8.12    Withholding. To the extent required by any applicable law, the Administrative Agent may withhold from any payment to any Lender an amount equivalent to any applicable withholding Tax. If any payment has been made to any Lender by the Administrative Agent without the applicable withholding Tax being withheld from such payment and the Administrative Agent has paid over the applicable withholding Tax to the Internal Revenue Service or any other Governmental Authority, or the Internal Revenue Service or any other Governmental Authority asserts a claim that the Administrative Agent did not properly withhold Tax from amounts paid to or for the account of any Lender because the appropriate form was not delivered or was not properly executed or because such Lender failed to notify the Administrative Agent of a change in circumstance which rendered the exemption from, or reduction of, withholding Tax ineffective or for any other reason, such Lender shall indemnify the Administrative Agent fully for all amounts paid, directly or indirectly, by the Administrative Agent as Tax or otherwise, including any penalties or interest and together with all expenses (including legal expenses, allocated internal costs and out-of-pocket expenses) incurred.

Section 8.13    Enforcement. The authority to enforce rights and remedies hereunder and under the other Loan Documents against any Loan Party or any of them shall be vested in, and all actions and proceedings at law in connection with such enforcement may be instituted and maintained by, the Administrative Agent or the Collateral Agent in accordance with Section 7.01 and the Collateral Documents for the benefit of each Lender, as applicable; provided, that the foregoing shall not prohibit (a) the Administrative Agent or the Collateral Agent from exercising on its own behalf the rights and remedies that inure to its benefit (solely in its capacity as Administrative Agent or Collateral Agent, as applicable) hereunder and under the other Loan Documents, (b) any Lender from exercising any enforcement rights, including setoff rights in accordance with Section 9.06 (subject to the terms of Section 2.08(c)), or (c) any Lender from filing proofs of claim or appearing and filing pleadings on its own behalf during the pendency of a proceeding relative to any Loan Party under any federal, state or foreign bankruptcy, insolvency, receivership or similar law; and provided, further, that if at any time there is no Person acting as the Administrative Agent or the Collateral Agent, as applicable, hereunder and under the other Loan Documents, then (i) the Required Lenders shall have the rights otherwise ascribed to the Administrative Agent or the Collateral Agent, as applicable, pursuant to Section 7.01 and the

91

Collateral Documents, as applicable and (ii) in addition to the matters set forth in clauses (b) and (c) of the preceding proviso and subject to Section 2.08(c), any Lender may, with the consent of the Required Lenders, enforce any rights and remedies available to it and as authorized by the Required Lenders.

(iv)    The Administrative Agent, acting for this purpose as an agent of the Borrower, shall maintain at one of its offices a copy of each Assignment and Acceptance delivered to it and a register for the recordation of the names and addresses of the Lenders, and principal amount of the Loans owing to, each Lender pursuant to the terms hereof from time to time (the “Register”). The entries in the Register shall be conclusive absent manifest error, and the Borrower, the Agents and the Lenders shall treat each Person whose name is recorded in the Register pursuant to the terms hereof as a Lender hereunder for all purposes of this Agreement, notwithstanding notice to the contrary. The Register shall be available for inspection by the Borrower and any Lender, at any reasonable time and from time to time upon reasonable prior notice.

(v)    The parties to each assignment shall deliver to, and for the account of, the Administrative Agent a processing and recordation fee in the amount of $3,500; provided, that the Administrative Agent may, in its sole discretion, elect to waive such processing and recordation fee in the case of any assignment. Upon its receipt of a duly completed Assignment and Acceptance executed by an assigning Lender and an assignee and the processing and recordation fee referred to above (unless waived as set forth above), the Administrative Agent shall accept such Assignment and Acceptance and record the information contained therein in the Register. No assignment shall be effective for purposes of this Agreement unless it has been recorded in the Register as provided in this paragraph.

(c)    (i) Any Lender may, without the consent of the Borrower or the Administrative Agent, sell participations to one or more banks or other entities (other than the Borrower or any of its Affiliates) (a “Participant”) in all or a portion of such Lender’s rights and obligations under this Agreement (including all or a portion of the Loans owing to it); provided, that (A) such Lender’s obligations under this Agreement shall remain unchanged, (B) such Lender shall remain solely responsible to the other parties hereto for the performance of such obligations, (C) the Borrower, the Agents and the other Lenders shall continue to deal solely and directly with such Lender in connection with such Lender’s rights and obligations under this Agreement. Any agreement or instrument (oral or written) pursuant to which a Lender sells such a participation shall provide that such Lender shall retain the sole right to exercise rights under and to enforce this Agreement and the other Loan Documents and to approve any amendment, modification or waiver of any provision of this Agreement and the other Loan Documents; provided, that (x) such agreement or instrument may provide that such Lender will not, without the consent of the Participant, agree to any amendment, modification or waiver described in Section 9.04(a)(i) or

94

clause (i) through (vi) of the first proviso to Section 9.08(b) that affects such Participant and (y) no other agreement (oral or written) in respect of the foregoing with respect to such Participant may exist between such Lender and such Participant. Subject to paragraph (c)(ii) of this Section, the Borrower agrees that each Participant shall be entitled to the benefits (and subject to the requirements and limitations) of Section 2.07 to the same extent as if it were the Lender from whom it obtained its participation and had acquired its interest by assignment pursuant to paragraph (b) of this Section. To the extent permitted by law, each Participant also shall be entitled to the benefits of Section 9.06 as though it were a Lender, provided, that such Participant agrees to be subject to Section 2.08(c) as though it were a Lender.

(ii)    A Participant shall not be entitled to receive any greater payment under Section 2.07 than the applicable Lender would have been entitled to receive with respect to the participation sold to such Participant, unless the sale of the participation to such Participant is made with the Borrower’s prior written consent (which shall not be unreasonably withheld or delayed) and the Borrower may withhold its consent if a Participant would be entitled to require greater payment than the applicable Lender under such Sections. A Participant that would be a Non-U.S. Lender if it were a Lender shall not be entitled to the benefits of Section 2.07 to the extent such Participant fails to comply with Section 2.07(e) as though it were a Lender.

(d)    Each Lender that sells a participation shall, acting solely for this purpose as a non-fiduciary agent of the Borrower, maintain a register on which it enters the name and address of each Participant and the principal amounts (and stated interest) of each Participant’s interest in the Loans or other obligations under the Loan Documents (the “Participant Register”); provided, that no Lender shall have any obligation to disclose all or any portion of the Participant Register to any Person (including the identity of any Participant or any information relating to a Participant’s interest in any loans or its other obligations under any Loan Document) except to the extent that such disclosure is necessary to establish that such loan or other obligation is in registered form under Section 5f.103-1(c) of the United States Treasury Regulations or Section 1.163-5(b) of the Proposed Treasury Regulations (or any amended or successor version). The entries in the Participant Register shall be conclusive absent manifest error, and such Lender shall treat each Person whose name is recorded in the Participant Register as the owner of such participation for all purposes of this Agreement notwithstanding any notice to the contrary.

(e)    Any Lender may at any time pledge or assign a security interest in all or any portion of its rights under this Agreement and its promissory note, if any, to secure obligations of such Lender, including any pledge or assignment to secure obligations to a Federal Reserve Bank or central bank having jurisdiction over such Lender, and this Section shall not apply to any such pledge or assignment of a security interest; provided, that no such pledge or assignment of a security interest shall release a Lender from any of its obligations hereunder or substitute any such pledgee or assignee for such Lender as a party hereto, and any such pledgee (other than a pledgee that is the Federal Reserve Bank or central bank) shall acknowledge in writing that its rights under such pledge are in all respects subject to the limitations applicable to the pledging Lender under this Agreement or the other Loan Documents.

95

Section 9.05    Expenses; Indemnity. (a) The Borrower agrees to pay all reasonable and documented out-of-pocket expenses incurred by the Agents and their respective Affiliates, in connection with the preparation of this Agreement and the other Loan Documents, including the reasonable and documented out of pocket fees, charges and disbursements of counsel for the Administrative Agent (limited, in the case of legal fees and disbursements, to one primary external counsel of the Administrative Agent, and one local external counsel of the Administrative Agent in each relevant jurisdiction), the administration of this Agreement (including expenses incurred in connection with due diligence and initial and ongoing Collateral examination to the extent incurred with the reasonable prior approval of the Borrower and the reasonable fees, disbursements and charges for counsel in each jurisdiction where Collateral is located) and any amendments, modifications or waivers of the provisions hereof or thereof (whether or not the Transactions hereby contemplated shall be consummated). The Borrower agrees to pay all reasonable and documented out-of-pocket expenses incurred by the Agents and their respective Affiliates in connection with the enforcement and protection of their rights in connection with this Agreement and the other Loan Documents, in connection with the Loans made hereunder, including the reasonable fees, charges and disbursements of counsel for the Agents or the Lenders (including external counsel and the reasonable and documented allocated costs of internal counsel for the Agents or any Lender); provided, that, absent any conflict of interest, the Agents and Lenders shall not be entitled to indemnification for the fees, charges or disbursements of more than one counsel in each jurisdiction.

(b)    The Borrower agrees to indemnify the Agents, each Lender and each Related Party of any of the foregoing Persons (each such Person being called an “Indemnitee”) against, and to hold each Indemnitee harmless from, any and all losses, penalties, claims, damages, liabilities and related expenses, including reasonable and documented counsel fees, charges and disbursements, incurred by or asserted against any Indemnitee arising out of, in any way connected with, or as a result of (i) the execution or delivery of this Agreement or any other Loan Document or any agreement or instrument contemplated hereby or thereby, the performance by the parties hereto and thereto of their respective obligations thereunder or the consummation of the Transactions and the other transactions contemplated hereby or thereby, (ii) any Loan or the use of the proceeds of the Loans or (iii) any claim, litigation, investigation or proceeding relating to any of the foregoing, whether or not the Borrower, its Subsidiaries, the MLP Entity, any Indemnitee or any other Person initiated or is a party thereto; provided, that such indemnity shall not, as to any Indemnitee, be available to the extent that such losses, penalties, claims, damages, liabilities or related expenses are determined by a final, nonappealable judgment rendered by a court of competent jurisdiction (A) to have resulted from the gross negligence, bad faith or willful misconduct of such Indemnitee (or any of such Indemnitee’s Related Parties) or (B) to arise from disputes solely among Indemnitees if such dispute (i) does not involve any action or inaction by the MLP Entity, the Borrower or any Subsidiary and (ii) is not related to any action by an Indemnitee in its capacity as Agent. Subject to and without limiting the generality of the foregoing sentence, the Borrower agrees to indemnify each Indemnitee against, and hold each Indemnitee harmless from, any and all losses, penalties, claims, damages, liabilities and related expenses, including reasonable and documented counsel or consultant fees, charges and disbursements, incurred by or asserted against any Indemnitee arising out of, in any way connected with, or as a result of (A) any Environmental Event or Environmental Claim related in any way to the Borrower or any of its Subsidiaries, or (B) any actual or alleged presence, Release or threatened Release of

96

Hazardous Materials at, under, on or from any Real Property currently or formerly owned, leased or operated by the Borrower or any of its Subsidiaries or by any predecessor of the Borrower or any of its Subsidiaries, or any property at which the Borrower or any of its Subsidiaries has sent Hazardous Materials for treatment, storage or disposal; provided, that such indemnity shall not, as to any Indemnitee, be available to the extent that such losses, penalties, claims, damages, liabilities or related expenses have resulted from the gross negligence, bad faith or willful misconduct of such Indemnitee, as determined by a final and nonappealable judgment in a court of competent jurisdiction. In the event of any of the foregoing, each Indemnitee shall be indemnified whether or not such amounts are caused by or arising, in whole or in part, out of the comparative, contributory or sole negligence of any Indemnitee (except to the extent of gross negligence as specified above). In no event shall any Indemnitee be liable to the MLP Entity, the Borrower, any Subsidiary Loan Party, or any other Subsidiary, or shall the MLP Entity, the Borrower or any Subsidiary be liable to any Indemnitee, for any consequential, indirect, special or punitive damages; provided, however, that nothing in this sentence shall limit the Borrower’s indemnification obligations set forth in this Section 9.05. No Indemnitee shall be liable for any damages arising from the use by unintended recipients of any information or other materials distributed to such unintended recipients by such Indemnitee through telecommunications, electronic or other information transmission systems in connection with this Agreement or the other Loan Documents or the transactions contemplated hereby or thereby other than for direct or actual damages resulting from the gross negligence, bad faith, or willful misconduct of such Indemnitee as determined by a court of competent jurisdiction. The provisions of this Section 9.05 shall remain operative and in full force and effect regardless of the expiration of the term of this Agreement, the consummation of the transactions contemplated hereby, the repayment of any of the Obligations, the invalidity or unenforceability of any term or provision of this Agreement or any other Loan Document, or any investigation made by or on behalf of any Agent or any Lender. All amounts due under this Section 9.05 shall be payable on written demand accompanied by reasonable documentation with respect to any reimbursement, indemnification or other amount requested.

(c)    This Section 9.05 shall not apply to Taxes.

Section 9.06    Right of Set-off. If an Event of Default shall have occurred and be continuing, each Lender and any Affiliate of a Lender is hereby authorized at any time and from time to time, to the fullest extent permitted by law, to set off and apply any and all deposits (general or special, time or demand, provisional or final) at any time held and other indebtedness at any time owing by such Lender or such Affiliate of a Lender to or for the credit or the account of any Loan Party or any Subsidiary that is not a Foreign Subsidiary, against any and all obligations of the Loan Parties, now or hereafter existing under this Agreement or any other Loan Document held by such Lender or such Affiliate of a Lender, irrespective of whether or not such Lender or such Affiliate of a Lender shall have made any demand under this Agreement or such other Loan Document and although the obligations may be unmatured. The rights of each Lender and each Affiliate of a Lender under this Section 9.06 are in addition to other rights and remedies (including other rights of set-off) that such Lender or such Affiliate of a Lender may have.

Section 9.07    Applicable Law. THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS (OTHER THAN AS EXPRESSLY SET FORTH IN OTHER LOAN DOCUMENTS) SHALL BE CONSTRUED IN ACCORDANCE WITH AND GOVERNED BY THE LAWS OF THE STATE OF NEW YORK.

97

Section 9.08    Waivers; Amendment. (a) No failure or delay of the Agents or any Lender in exercising any right, power or remedy hereunder or under any Loan Document shall operate as a waiver thereof, nor shall any single or partial exercise of any such right, power or remedy, or any abandonment or discontinuance of steps to enforce such a right, power or remedy, preclude any other or further exercise thereof or the exercise of any other right, power or remedy. The rights, powers and remedies of the Agents and the Lenders hereunder and under the other Loan Documents are cumulative and are not exclusive of any rights or remedies that they would otherwise have. No waiver of any provision of this Agreement or any other Loan Document or consent to any departure by the MLP Entity, the Borrower or any Subsidiary Loan Party therefrom shall in any event be effective unless the same shall be permitted by paragraph (b) below, and then such waiver or consent shall be effective only in the specific instance and for the purpose for which given. No notice or demand on the MLP Entity, the Borrower or any Subsidiary Loan Party in any case shall entitle such Person to any other or further notice or demand in similar or other circumstances.

(b)    Neither this Agreement nor any other Loan Document nor any provision hereof or thereof may be waived, amended or modified except (x) in the case of this Agreement, pursuant to an agreement or agreements in writing entered into by the Borrower and the Required Lenders (or the Administrative Agent with the consent of the Required Lenders) and (y) in the case of any other Loan Document, pursuant to an agreement or agreements in writing entered into by each Loan Party party thereto and the Collateral Agent and consented to by the Required Lenders; provided, that no such agreement shall

(i)    decrease or forgive the principal amount of, or extend the final maturity of, or decrease the rate of interest on any Loan, without the prior written consent of each Lender directly affected thereby; provided, that any amendment to the financial covenant definitions in this Agreement shall not constitute a reduction in the rate of interest for purposes of this clause (i) and provided, further, that, any waiver of all or a portion of any post-default increase in interest rates shall be effective upon the consent of the Required Lenders,

(ii)    increase or extend the Loans of any Lender or decrease the fees payable to any Lender without the prior written consent of such Lender (it being understood that waivers or modifications of conditions precedent, covenants, Defaults or Events of Default shall not constitute an increase in or extension of the Loans of any Lender),

(iii)    extend any date on which payment of the principal amount of any Loan or interest on any Loan or any Fees or any other payment hereunder is due, without the prior written consent of each Lender adversely affected thereby,

(iv)    change the order of application of any amounts from the application thereof set forth in the applicable provisions of Section 2.08(b), Section 2.08(c) or Section 9.21 or change any provision hereof that establishes the pro rata treatment

98

among the Lenders in a manner that would by such change alter the pro rata sharing or other pro rata treatment of the Lenders, without the prior written consent of each Lender adversely affected thereby,

(v)    amend or modify the provisions of this Section 9.08 or any requirement of Article IV or the definition of the terms “Required Lenders” or any other provision hereof specifying the number or percentage of Lenders required to waive, amend or modify any rights hereunder or make any determination or grant any consent hereunder, without the prior written consent of each Lender, and

(vi)    release all or substantially all the Collateral or release all or substantially all of the value of the Guarantees of the MLP Entity and the Subsidiary Loan Parties without the prior written consent of each Lender (except, in the case of any Subsidiary Loan Party, to the extent of a release in connection with a transaction expressly permitted in Sections 6.02 or 6.05);

provided, further, that no such agreement shall amend, modify or otherwise affect the rights or duties of the Administrative Agent or the Collateral Agent hereunder or under the other Loan Documents, without the prior written consent of such Administrative Agent or Collateral Agent, as applicable. Each Lender shall be bound by any waiver, amendment or modification authorized by this Section 9.08 and any consent by any Lender pursuant to this Section 9.08 shall bind any assignee of such Lender.

(c)    With the consent of each Loan Party, as applicable, Administrative Agent and/or Collateral Agent may (in their respective sole discretion, or shall, to the extent required by any Loan Document) enter into any amendment, modification or waiver of any Loan Document, or enter into any new agreement or instrument, to effect the granting, perfection, protection, expansion or enhancement of any security interest in any Collateral or additional property to become Collateral for the benefit of the Secured Parties, or as required by local law to give effect to, or protect any security interest for the benefit of the Secured Parties, in any property or so that the security interests therein comply with applicable law.

(d)    Notwithstanding the foregoing, any Loan Document may be amended, modified, supplemented or waived with the written consent of the Administrative Agent and the Borrower without the need to obtain the consent of any Lender (i) in accordance with Sections 6.10, 6.11 and 6.12 or (ii) if such amendment, modification, supplement or waiver is executed and delivered in order to cure an ambiguity, omission, mistake or defect in such Loan Document; provided, that in no event will the Administrative Agent be required to substitute its judgment for the judgment of the Lenders or the Required Lenders, and the Administrative Agent may in all circumstances seek the approval of the Required Lenders, the affected Lenders or all Lenders in connection with any such amendment, modification, supplement or waiver.

Section 9.09    Interest Rate Limitation. Notwithstanding anything herein to the contrary, if at any time the applicable interest rate, together with all fees and charges that are treated as interest under applicable law (collectively, the “Charges”), as provided for herein or in any other document executed in connection herewith, or otherwise contracted for, charged, received, taken or reserved by any Lender, shall exceed the maximum lawful rate (the “Maximum Rate”) that

99

may be contracted for, charged, taken, received or reserved by such Lender in accordance with applicable law, the rate of interest payable hereunder, together with all Charges payable to such Lender, shall be limited to the Maximum Rate, provided, that such excess amount shall be paid to such Lender on subsequent payment dates to the extent not exceeding the legal limitation.

Section 9.10    Entire Agreement. This Agreement, the other Loan Documents [and the agreements regarding certain Fees referred to herein] constitute the entire contract between the parties relative to the subject matter hereof. Any previous agreement among or representations from the parties or their Affiliates with respect to the subject matter hereof is superseded by this Agreement and the other Loan Documents. Nothing in this Agreement or in the other Loan Documents, expressed or implied, is intended to confer upon any party other than the parties hereto and thereto any rights, remedies, obligations or liabilities under or by reason of this Agreement or the other Loan Documents.

Section 9.11    Waiver of Jury Trial. EACH PARTY HERETO HEREBY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION DIRECTLY OR INDIRECTLY ARISING OUT OF, UNDER OR IN CONNECTION WITH THIS AGREEMENT OR ANY OF THE OTHER LOAN DOCUMENTS. EACH PARTY HERETO (i) CERTIFIES THAT NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER AND (ii) ACKNOWLEDGES THAT IT AND THE OTHER PARTIES HERETO HAVE BEEN INDUCED TO ENTER INTO THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS, AS APPLICABLE, BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION 9.11.

Section 9.12    Severability. In the event any one or more of the provisions contained in this Agreement or in any other Loan Document should be held invalid, illegal or unenforceable in any respect, the validity, legality and enforceability of the remaining provisions contained herein and therein shall not in any way be affected or impaired thereby. The parties shall endeavor in good-faith negotiations to replace the invalid, illegal or unenforceable provisions with valid provisions the economic effect of which comes as close as possible to that of the invalid, illegal or unenforceable provisions.

Section 9.13    Counterparts. This Agreement may be executed in one or more counterparts, each of which shall constitute an original but all of which, when taken together, shall constitute but one contract, and shall become effective as provided in Section 9.03. Delivery of an executed counterpart to this Agreement by facsimile transmission or an electronic transmission of a PDF copy thereof shall be as effective as delivery of a manually signed original. Any such delivery shall be followed promptly by delivery of the manually signed original.

Section 9.14    Headings. Article and Section headings and the Table of Contents used herein are for convenience of reference only, are not part of this Agreement and are not to affect the construction of, or to be taken into consideration in interpreting, this Agreement.

Section 9.15    Jurisdiction; Consent to Service of Process. (a) Each of the Borrower, the Agents and the Lenders hereby irrevocably and unconditionally submits, for itself and its property, to the exclusive jurisdiction of any New York State court or federal court of the United States of America sitting in New York County, and any appellate court from any thereof, in any action or proceeding arising out of or relating to this Agreement or the other Loan Documents, or for recognition or enforcement of any judgment, and each of the parties hereto hereby irrevocably and unconditionally agrees that all claims in respect of any such action or proceeding may be heard and determined in such New York State or, to the extent permitted by law, in such federal court. The Borrower further irrevocably consents to the service of process in any action or proceeding in such courts by the mailing thereof by any parties thereto by registered or certified mail, postage prepaid, to the Borrower at the address specified for the Loan Parties in Section 9.01. Each of the parties hereto agrees that a final judgment in any such action or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by law. Nothing in this Agreement (other than Section 8.09) shall affect any right that any Lender may otherwise have to bring any action or proceeding relating to this Agreement or the other Loan Documents against the Borrower or any Loan Party or their properties in the courts of any jurisdiction.

(b)    Each of the Borrower, the Agents and the Lenders hereby irrevocably and unconditionally waives, to the fullest extent it may legally and effectively do so, any objection which it may now or hereafter have to the laying of venue of any suit, action or proceeding arising out of or relating to this Agreement or the other Loan Documents in any New York State or federal court sitting in New York County. Each of the parties hereto hereby irrevocably waives, to the fullest extent permitted by law, the defense of an inconvenient forum to the maintenance of such action or proceeding in any such court.

Section 9.16    Confidentiality. Each of the Lenders and each of the Agents agrees that it shall maintain in confidence any information relating to the Borrower and its Subsidiaries and their respective Affiliates furnished to it by or on behalf of the Borrower or the other Loan Parties or such Subsidiary or Affiliate (other than information that (x) has become generally available to the public other than as a result of a disclosure by such party in breach of this Agreement, (y) has been independently developed by such Lender or such Agent without violating this Section 9.16 or (z) was available to such Lender or such Agent from a third party having, to such Person’s actual knowledge, no obligations of confidentiality to the Borrower or any of its Subsidiaries or any such Affiliate) and shall not reveal the same other than to its directors, trustees, officers, employees, agents and advisors with a need to know or to any Person that approves or administers the Loans on behalf of such Lender (so long as each such Person shall have been instructed to keep the same confidential in accordance with this Section 9.16), except: (i) to the extent necessary to comply with law or any legal process or the regulatory (including self-regulatory) or supervisory requirements of any Governmental Authority (including bank examiners), the National Association of Insurance Commissioners or of any securities exchange on which securities of the disclosing party or any Affiliate of the disclosing party are listed or traded, (ii) as part of reporting or review procedures to Governmental Authorities (including bank examiners) or the National Association of Insurance Commissioners, (iii) to its parent companies, Affiliates, and their respective directors, officers, employees and agents, including accountants, legal counsel and other advisors (so long as each such Person shall have been instructed to keep the same confidential in

101

accordance with this Section 9.16), (iv) to any Agent, any other Lender or any other party of any Loan Document and the Affiliates of each, (v) in connection with the exercise of any remedies under any Loan Document or in order to enforce its rights under any Loan Document in a legal proceeding, (vi) to any prospective assignee of, or prospective Participant in, any of its rights under this Agreement (so long as such Person shall have been instructed to keep the same confidential in accordance with this Section 9.16 or on terms at least as restrictive as those set forth in this Section 9.16), (vii) to any direct or indirect contractual counterparty in Swap Agreements or such contractual counterparty’s professional advisor (so long as each such contractual counterparty agrees to be bound by the provisions of this Section 9.16 or on terms at least as restrictive as those set forth in Section 9.16 and each such professional advisor shall have been instructed to keep the same confidential in accordance with this Section 9.16), (viii) with the consent of the Borrower and (ix) on a confidential basis to any rating agency in connection with rating the Borrower or its Subsidiaries or this Agreement. If a Lender or an Agent is requested or required to disclose any such information (other than to its bank examiners and similar regulators, or to internal or external auditors) pursuant to or as required by law or legal process or subpoena, then, to the extent reasonably practicable, it shall give prompt notice thereof to the Borrower so that the Borrower may seek an appropriate protective order and such Lender or Agent will cooperate with the Borrower (or the applicable Subsidiary or Affiliate) in seeking such protective order.

Section 9.17    Communications. (a) Delivery.

(i)    Each Loan Party hereby agrees that it will use all reasonable efforts to provide to the Administrative Agent all information, documents and other materials that it is obligated to furnish to the Administrative Agent pursuant to this Agreement and any other Loan Document, including, without limitation, all notices, requests, financial statements, financial and other reports, certificates and other information materials, but excluding any such communication that (A) relates to the payment of any principal or other amount due under this Agreement prior to 5:00 p.m., New York City time on the scheduled date therefor, (B) provides notice of any Default or Event of Default under this Agreement or (C) is required to be delivered to satisfy any condition precedent to the effectiveness of this Agreement and/or any extension of credit hereunder (all such non-excluded communications collectively, the “Communications”), by transmitting the Communications in an electronic/soft medium in a format reasonably acceptable to the Administrative Agent at the address referenced in Section 9.01(a)(ii). Nothing in this Section 9.17 shall prejudice the right of the Agents, the Lenders or any Loan Party to give any notice or other communication pursuant to this Agreement or any other Loan Document in any other manner specified in this Agreement or any other Loan Document.

(ii)    Each Lender agrees that notice to it (as provided in the next sentence) specifying that the Communications have been posted to the Platform (as defined below) shall constitute effective delivery of the Communications to such Lender for purposes of the Loan Documents. Each Lender agrees (A) to notify the Administrative Agent in writing (including by electronic communication) from time to time of such Lender’s e-mail address to which the foregoing notice may be sent by electronic transmission and (B) that the foregoing notice may be sent to such e-mail address.

102

(b)    Posting. Each Loan Party further agrees that the Administrative Agent may make the Communications available to the Lenders by posting the Communications on Intralinks or a substantially similar electronic transmission system (the “Platform”). The Borrower hereby acknowledges that (i) the Administrative Agent will make available to the Lenders materials and/or information provided by or on behalf of the Borrower hereunder (collectively, “Borrower Materials”) by posting the Borrower Materials on the Platform and (ii) certain of the Lenders (each, a “Public Lender”) may have personnel who do not wish to receive material non-public information with respect to the Borrower or its Affiliates, or the respective securities of any of the foregoing, and who may be engaged in investment and other market-related activities with respect to such Persons’ securities. The Borrower hereby agrees that it will use commercially reasonable efforts to identify that portion of the Borrower Materials that may be distributed to the Public Lenders and that (w) all such Borrower Materials shall be clearly and conspicuously marked “PUBLIC” which, at a minimum, shall mean that the word “PUBLIC” shall appear prominently on the first page thereof; (x) by marking Borrower Materials “PUBLIC,” the Borrower shall be deemed to have authorized the Administrative Agent and the Lenders to treat such Borrower Materials as not containing any material non-public information (although it may be sensitive and proprietary) with respect to the Borrower or its Affiliates or their respective securities for purposes of United States federal and state securities laws; (y) all Borrower Materials marked “PUBLIC” are permitted to be made available through a portion of the Platform designated “Public Side Information;” and (z) the Administrative Agent shall be entitled to treat any Borrower Materials that are not marked “PUBLIC” as being suitable only for posting on a portion of the Platform not designated “Public Side Information.” Notwithstanding the foregoing, the Borrower shall not be under any obligation to mark any Borrower Materials “PUBLIC” to the extent the Borrower determines that such Borrower Materials contain material non-public information with respect to the Borrower or its Affiliates or their respective securities for purposes of United States federal and state securities laws.

(c)    Platform. The Platform is provided “as is” and “as available.” The Agent Parties (as defined below) do not warrant the accuracy or completeness of the Communications, or the adequacy of the Platform and expressly disclaim liability for errors or omissions in the Communications. No warranty of any kind, express, implied or statutory, including, without limitation, any warranty of merchantability, fitness for a particular purpose, non-infringement of third party rights or freedom from viruses or other code defects, is made by any Agent Party in connection with the Communications or the Platform. In no event shall the Administrative Agent, the Collateral Agent or any of its or their Affiliates or any of their respective officers, directors, employees, agents advisors or representatives (collectively, “Agent Parties”) have any liability to the Loan Parties, any Lender or any other Person or entity for damages of any kind, including, without limitation, direct or indirect, special, incidental or consequential damages, losses or expenses (whether in tort, contract or otherwise) arising out of any Loan Party’s or the Administrative Agent’s or the Collateral Agent’s transmission of communications through the internet, except to the extent the liability of any Agent Party is found in a final non-appealable judgment by a court of competent jurisdiction to have resulted primarily from such Agent Party’s gross negligence or willful misconduct.

103

Section 9.18    Release of Liens and Guarantees. (a) In the event that (i) the Borrower or any Subsidiary Loan Party conveys, sells, leases, assigns, transfers or otherwise disposes of all or any portion of its assets (including the Equity Interests of any of its Subsidiaries) to a Person that is not (and is not required to become) a Loan Party in a transaction not prohibited by the Loan Documents (other than any sale or conveyance of any assets to Eddy County in connection with the IRB Transactions), (ii) any Restricted Subsidiary becomes an Unrestricted Subsidiary (other than any Included Entity, any Ohio Joint Venture or, from and after the Opt-In Time, the Double E Joint Venture) or (iii) any Subsidiary ceases to be a Revolver Loan Party, then, in any of such cases, the Administrative Agent and the Collateral Agent shall promptly (and the Lenders hereby authorize the Administrative Agent and the Collateral Agent to) take such action and execute any such documents as may be reasonably requested by the Borrower and at the Borrower’s sole cost and expense to release any Liens created by any Loan Document in respect of such Equity Interests, Subsidiary Loan Party or assets that are the subject of such disposition, release any Liens created by any Loan Document in respect of Equity Interests of any Restricted Subsidiary that becomes an Unrestricted Subsidiary (other than any Included Entity, any Ohio Joint Venture or, from and after the Opt-In Time, the Double E Joint Venture), and release any Guarantees of the Obligations and release any Liens granted to secure the Obligations, in each case by a Person that ceases to be a Subsidiary of the Borrower or that ceases to be a Subsidiary Loan Party as a result of a transaction described above. Any representation, warranty or covenant contained in any Loan Document relating to any such Equity Interests or assets shall no longer be deemed to be made once such Equity Interests or assets are so conveyed, sold, leased, assigned, transferred or disposed of. Any sale or conveyance of any assets to Eddy County in connection with the IRB Transactions shall be subject to all Liens thereon created under the Loan Documents, and such Liens created under the Loan Documents shall continue in effect after such sale or conveyance.

(b)    When all the Obligations are paid in full in cash (other than contingent indemnification obligations), the Collateral Documents, the Guarantees made therein, the Security Interest (as defined therein) and all other security interests granted thereby shall terminate, and each Loan Party shall automatically be released from its obligations thereunder and the security interests in the Collateral granted by any Loan Party shall automatically be released. At such time, the Administrative Agent and the Collateral Agent agree to take such actions as are reasonably requested by the Borrower at the Borrower’s expense to evidence and effectuate such termination and release of the Guarantees, Liens and security interests created by the Loan Documents.

(c)    Authorizations for each release and termination specified in this Section 9.18 shall be required only to the extent required by Section 8.10.

Section 9.19    Judgment. If for the purposes of obtaining judgment in any court it is necessary to convert a sum due hereunder in one currency into another currency, the parties hereto agree, to the fullest extent that they may effectively do so, that the rate of exchange used shall be that at which in accordance with normal banking procedures the Administrative Agent could purchase the first mentioned currency with such other currency at the Administrative Agent’s office on the Business Day preceding that on which final judgment is given.

Section 9.20    No Fiduciary Duty. Each Agent, each Lender and their respective Affiliates (collectively, solely for purposes of this paragraph, the “Lenders”), may have economic interests that conflict with those of the MLP Entity, the Borrower and the Subsidiaries of the Borrower.

104

The Borrower hereby agrees that subject to applicable law, nothing in the Loan Documents or otherwise will be deemed to create an advisory, fiduciary or agency relationship or fiduciary or other implied duty between the Lenders and the Loan Parties, their equity holders or their Affiliates. The Borrower hereby acknowledges and agrees that (i) the transactions contemplated by the Loan Documents are arm’s-length commercial transactions between the Lenders, on the one hand, and the Loan Parties, on the other, (ii) in connection therewith and with the process leading to such transaction none of the Lenders is acting as the agent or fiduciary of any Loan Party, its management, equity holders, creditors or any other person, (iii) no Lender has assumed an advisory or fiduciary responsibility in favor of any Loan Party with respect to the transactions contemplated hereby or the process leading thereto (irrespective of whether any Lender or any of its Affiliates has advised or is currently advising such Loan Party on other matters) or any other obligation to any Loan Party except the obligations expressly set forth in the Loan Documents, (iv) the Borrower and each other Loan Party has consulted its own legal and financial advisors to the extent it has deemed appropriate and (v) the Lenders may be engaged in a broad range of transactions that involve interests that differ from those of the Borrower and its Affiliates and no Lender has an obligation to disclose any such interests to the Borrower or its Affiliates. The Borrower further acknowledges and agrees that it is responsible for making its own independent judgment with respect to such transactions and the process leading thereto.

Section 9.21    Application of Funds. Subject to the Intercreditor Agreement, after the exercise of remedies provided for in Section 7.01 (or after the Loans have automatically become immediately due and payable), any amounts received by the Administrative Agent from the Collateral Agent pursuant to any Collateral Document and any other amounts received by the Administrative Agent on account of the Loan Document Obligations shall be applied by the Administrative Agent in the following order:

(a)    First, to payment of that portion of the Loan Document Obligations constituting Fees, indemnities, expenses and other amounts (other than principal and interest but including Fees, charges and disbursements of counsel to the Administrative Agent and the Collateral Agent) payable to the Administrative Agent and the Collateral Agent in their respective capacities as such;

(b)    Second, to payment of that portion of the Loan Document Obligations constituting Fees, indemnities and other amounts (other than principal and interest) payable to the Lenders (including Fees, charges and disbursements of counsel to the respective Lenders) arising under the Loan Documents, ratably among them in proportion to the respective amounts described in this clause Second payable to them;

(c)    Third, to payment of that portion of the Loan Document Obligations constituting accrued and unpaid interest on the Loans and other Obligations arising under the Loan Documents, ratably among the Lenders in proportion to the respective amounts described in this clause Third payable to them; and

(d)    Last, the balance, if any, after all of the Loan Document Obligations have been indefeasibly paid in full, to the Borrower or as otherwise required by Law.
