(vi) Cash Collateral (or the appropriate portion thereof) provided to reduce any Issuing Bank’s Fronting Exposure or other obligations shall be released promptly following (i) the elimination of the applicable Fronting Exposure or payment in full of all other obligations giving rise thereto (including by the termination of Defaulting Lender status of the applicable Lender (or, as appropriate, its assignee following compliance with Section 10.04(f))) or (ii) the Collateral Agent’s good faith determination that there exists excess Cash Collateral; provided, however, that the Person providing Cash Collateral and each Issuing Bank may agree that Cash Collateral shall be held to support future anticipated Fronting Exposure and other obligations and shall remain subject to the security interest granted pursuant to the Loan Documents; and provided further that Cash Collateral furnished by or on behalf of a Borrower shall not be released during the continuance of an Event of Default (and following application as provided in this clause (j) may be subject to the terms of Section 2.16(b)).

-31-

(k) No Issuing Bank shall be under any obligation to issue any Letter of Credit if any Lender is at that time a Defaulting Lender, unless the applicable Borrower or such Defaulting Lender has Cash Collateralized such Issuing Bank’s actual or potential Fronting Exposure (after giving effect to Section 2.18(a)(iii)) with respect to the Defaulting Lender arising from the Letter of Credit then proposed to be issued.

Section 2.05. Funding Of Borrowings. (a) Each Lender shall make each Loan to be made by it hereunder on the proposed date of the related Borrowing by wire transfer of immediately available funds by 12:00 noon, New York City time, to the account of the Administrative Agent most recently designated by it for such purpose by notice to the Lenders. The Administrative Agent will make such Loans available to the applicable Borrower by promptly crediting the Loan amounts so received, in like funds, to such account as designated by such Borrower in the applicable Borrowing Request; provided that ABR Loans made to finance the reimbursement of an LC Disbursement as provided in Section 2.04(e) shall be remitted by the Administrative Agent to the applicable Issuing Bank.

(b) Unless the Administrative Agent shall have received notice from a Lender prior to the proposed date (or, in the case of a requested ABR Borrowing for which notice has been provided by the Company on the same date of the proposed disbursement, the proposed time) of any Borrowing that such Lender will not make available to the Administrative Agent such Lender’s share of such Borrowing, the Administrative Agent may assume that such Lender has made such share available on such date in accordance with paragraph (a) of this Section 2.05 and may, in reliance upon such assumption, make available to the applicable Borrower a corresponding amount. In such event, if a Lender has not in fact made its share of a Borrowing available to the Administrative Agent, then the applicable Lender and Borrower severally agree to pay to the Administrative Agent forthwith on demand such corresponding amount with interest thereon, for each day from and including the date such amount is made available to such Borrower to but excluding the date of payment to the Administrative Agent, at (i) in the case of such Lender, 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, or (ii) in the case of a Borrower, the interest rate applicable to ABR Loans. If such Lender pays such amount to the Administrative Agent, then such amount shall constitute such Lender’s Loan included in such Borrowing.

Section 2.06. Interest Elections. (a) Each Borrowing initially shall be of the Type specified in the applicable Borrowing Request and, in the case of a Eurodollar Borrowing, shall have an initial Interest Period as specified in such Borrowing Request. The Company, on its own behalf or on behalf of a Pipeline Company Borrower, may thereafter elect at any time and from time to time on any Business Day to convert such Borrowing to a different Type or to continue such Borrowing and, in the case of a Eurodollar Borrowing, may elect Interest Periods therefor, all as provided in this Section 2.06. The Company, on its own behalf or on behalf of a Pipeline Company Borrower, may elect different options with respect to different portions of the affected Borrowing, in which case each such portion shall be allocated ratably among the Lenders holding the Loans comprising such Borrowing, and the Loans comprising each such portion shall be considered a separate Borrowing.

-32-

(b) To make an election pursuant to this Section 2.06, a Borrower shall notify the Administrative Agent of such election by telephone not later than 12:00 noon, New York City time, three Business Days before the proposed effective date of such election. Each such telephonic Interest Election Request shall be irrevocable and shall be confirmed promptly by hand delivery or telecopy to the Administrative Agent of a written Interest Election Request in a form approved by the Administrative Agent and signed by such Borrower.

(c) Each telephonic and written Interest Election Request shall specify the following information in compliance with Section 2.02:

(i) the Borrowing to which such Interest Election Request applies and, if different options are being elected with respect to different portions thereof, the portions thereof to be allocated to each resulting Borrowing (in which case the information to be specified pursuant to clauses (iii) and (iv) below shall be specified for each resulting Borrowing);

(ii) the effective date of the election made pursuant to such Interest Election Request, which shall be a Business Day;

(iii) whether the resulting Borrowing is to be an ABR Borrowing or a Eurodollar Borrowing; and

(iv) if the resulting Borrowing is a Eurodollar Borrowing, the Interest Period to be applicable thereto after giving effect to such election, which shall be a period contemplated by the definition of the term “Interest Period”.

If any such Interest Election Request requests a Eurodollar Borrowing but does not specify an Interest Period, then the Borrower shall be deemed to have selected an Interest Period of one month’s duration.

(d) Promptly following receipt of an Interest Election Request, the Administrative Agent shall advise each Lender of the details thereof and of such Lender’s portion of each resulting Borrowing.

(e) If a Borrower fails to deliver a timely Interest Election Request with respect to a Eurodollar Borrowing prior to the end of the Interest Period applicable thereto, then, unless such Borrowing is repaid as provided herein, at the end of such Interest Period such Borrowing shall be converted to an ABR Borrowing. Notwithstanding any contrary provision hereof, if an Event of Default has occurred and is continuing and the Administrative Agent, at the request of the Majority Lenders, so notifies any Borrower, then, so long as an Event of Default is continuing (i) no outstanding Borrowing may be converted to or continued as a Eurodollar Borrowing and (ii) unless repaid, each Eurodollar Borrowing shall be converted to an ABR Borrowing at the end of the Interest Period applicable thereto.

-33-

Section 2.07. Optional and Mandatory Termination and Reduction of Commitments . (a) Unless previously terminated, the Commitments shall terminate on the Maturity Date.

(b) The Company may at any time terminate, or from time to time reduce, the unused portions of the Commitments; provided that (i) unless the Company is reducing the Commitments in order to comply with its obligations under Section 5.10, each partial reduction of the Commitments shall be in an amount that is an integral multiple of $1,000,000 and not less than $10,000,000, and (ii) the Company shall not terminate or reduce the Commitments if, after giving effect to any concurrent prepayment of Loans in accordance with Section 2.09, the Outstandings would exceed the aggregate amount of the Commitments.

(c) The Company shall notify the Administrative Agent of any election to terminate or reduce the Commitments under paragraph (b) of this Section 2.07, or any required reduction of the Commitments under paragraph (d) or (e) of this Section 2.07, at least three Business Days prior to the effective date of such termination or reduction, specifying such election and the effective date thereof. Promptly following receipt of any notice, the Administrative Agent shall advise the Lenders of the contents thereof. Each notice delivered by the Company pursuant to this Section 2.07 shall be irrevocable; provided that a notice of termination of the Commitments delivered by the Company may state that such notice is conditioned upon the effectiveness of other credit facilities, in which case such notice may be revoked by the Company (by notice to the Administrative Agent on or prior to the specified effective date) if such condition is not satisfied.

(d) Unless the Collateral Release Date shall have occurred, within five days after the occurrence of a Mandatory Asset Reduction Event, the Commitments shall be ratably reduced (but not below zero) by an aggregate amount equal to the related Mandatory Asset Reduction Amount.

(e) Within three Business Days after the occurrence of a Pipeline Ownership Event, the Commitments shall be ratably reduced (but not below zero) by an amount equal to (i) if before such Pipeline Ownership Event, the Pipeline Ownership Percentage is equal to or less than 100%, 100% of the Net Proceeds of the Disposition giving rise to such Pipeline Ownership Event and (ii) if before such Pipeline Ownership Event, the Pipeline Ownership Percentage is greater than 100%, a percentage of the Net Proceeds of the Disposition giving rise to such Pipeline Ownership Event equal to (x) 100% minus the Pipeline Ownership Percentage immediately after such Disposition, divided by (y) the Pipeline Ownership Percentage immediately before such Disposition minus the Pipeline Ownership Percentage immediately after such Disposition.

(f) Any termination or reduction of the Commitments hereunder, whether optional or mandatory, shall be permanent. Each reduction of the Commitments shall be made ratably among the Lenders in accordance with their respective Commitments.

-34-

Section 2.08. Repayment of Loans; Evidence of Debt. (a) Each Borrower hereby unconditionally promises to pay on the Maturity Date to the Administrative Agent for the account of each Lender the then unpaid principal amount of each Loan made to such Borrower.

(b) Each Lender shall maintain in accordance with its usual practice an account or accounts evidencing the indebtedness of each Borrower to such Lender resulting from each Loan made by such Lender to such Borrower, including the amounts of principal and interest payable and paid to such Lender from time to time hereunder.

(c) The Administrative Agent shall maintain accounts in which it shall record (i) the amount of each Loan made hereunder, the Type thereof, the Interest Period applicable thereto and the Borrower to whom such Loan is made, (ii) the amount of any principal or interest due and payable or to become due and payable to each Lender hereunder on account of each Loan from the relevant Borrower to whom such Loan was made and (iii) the amount of any sum received by the Administrative Agent hereunder for the account of the Lenders and each Lender’s share thereof.

(d) The entries made in the accounts maintained pursuant to paragraph (b) or (c) of this Section 2.08 shall, to the extent permitted by applicable law, be prima facie evidence of the existence and amounts of the obligations of each Borrower recorded therein absent manifest error; provided that the failure of any Lender or the Administrative Agent to maintain any such account or any error therein shall not in any manner affect the obligation of each Borrower to repay the Loans made to such Borrower in accordance with the terms of this Agreement.

(e) Any Lender may request that Loans made by it be evidenced by a Note. In such event, the applicable Borrower shall prepare, execute and deliver to such Lender a Note or Notes payable to the order of such Lender (or, if requested by such Lender, to such Lender and its registered assigns). Thereafter, the Loans evidenced by such Note and interest thereon shall at all times (including after assignment pursuant to Section 10.04) be represented by one or more Notes in such form payable to the order of the payee named therein (or, if such Note is a registered note, to such payee and its registered assigns).

Section 2.09. Optional and Mandatory Prepayment of Loans. (a) Any Borrower shall have the right at any time and from time to time to prepay any Borrowing in whole or in part (without premium or penalty but subject to Section 2.14), subject to prior notice in accordance with paragraph (b) of this Section 2.09. All or any portion of any Loan prepaid may be borrowed and reborrowed in accordance with the terms and provisions of this Agreement.

(b) A Borrower shall notify the Administrative Agent by telephone (confirmed by telecopy) of any optional prepayment hereunder (i) in the case of prepayment of a Eurodollar Borrowing, not later than 12:00 noon, New York City time, two Business Days before the date of prepayment, or (ii) in the case of prepayment of an ABR Borrowing, not later than 12:00 noon, New York City time, on the date of prepayment. Each such notice shall be irrevocable and shall specify the prepayment date and the principal amount of each Borrowing or portion thereof to be prepaid; provided that, if a notice of prepayment is given in connection with a conditional notice of termination of the Commitments as contemplated by Section 2.07(c), then such notice of prepayment may be revoked if such notice of termination is revoked in accordance with Section 2.07(c). Promptly following receipt of any such notice relating to a Borrowing, the Administrative Agent shall advise the Lenders of the contents thereof. Each optional partial prepayment of any Borrowing shall be in a minimum amount of $5,000,000 or a larger integral multiple of $1,000,000. Each optional prepayment of a Borrowing shall be applied ratably to the Loans included in the prepaid Borrowing. Each prepayment shall be accompanied by accrued and unpaid interest to the extent required by Section 2.11

-35-

(c) If on any date (including any date on which a mandatory reduction of Commitments occurs pursuant to Section 2.07(d) or (e)) the aggregate Outstandings exceed the then aggregate Commitments, then, without notice or demand, the Company shall promptly cause to be prepaid the principal amount of the Loans and any unreimbursed LC Disbursements in an amount equal to such excess and, if all Loans and unreimbursed LC Disbursements shall have been prepaid, promptly cause to be Cash Collateralized outstanding Letters of Credit by an amount equal to any remaining excess.

Section 2.10. Fees. (a) The Company agrees to pay to the Administrative Agent for the account of each Lender (except for any Defaulting Lender) a commitment fee, which shall accrue at the Applicable Rate on the daily amount of the excess of the Commitment of such Lender over such Lender’s Outstandings during the period from and including the date hereof to but excluding the date on which such Commitment terminates.

(b) The Company agrees to pay (i) to the Administrative Agent for the account of each Lender a participation fee with respect to its participations in Letters of Credit, which shall accrue at the same Applicable Rate used to determine the interest rate applicable to Eurodollar Loans on the average daily amount of such Lender’s LC Exposure (excluding any portion thereof attributable to unreimbursed LC Disbursements) during the period from and including the Effective Date to but excluding the later of the date on which such Lender’s Commitment terminates and the date on which such Lender ceases to have any LC Exposure, (ii) to each Issuing Bank a fronting fee, which shall accrue at the rate of 0.20% per annum on the average daily amount of the LC Exposure (excluding any portion thereof attributable to unreimbursed LC Disbursements) with respect to each Letter of Credit issued by such Issuing Bank during the period from and including the Effective Date to but excluding the later of the date of termination of the Commitments and the date on which there ceases to be any LC Exposure with respect to Letters of Credit issued by such Issuing Bank and (iii) to each Issuing Bank, such Issuing Bank’s standard fees with respect to the issuance, amendment, renewal or extension of any Letter of Credit issued by it or processing of drawings thereunder.

(c) Fees accrued pursuant to paragraphs (a), (b)(i) and (b)(ii) above, through and including the last day of March, June, September and December of each year shall be payable on the third Business Day following each such last day, commencing on the first such date to occur after the Effective Date; provided that all such fees for the account of the Lenders shall be payable on the date on which the Commitments terminate and any such fees accruing after the date on which the Commitments terminate shall be payable on demand. All such fees shall be computed on the basis of a year of 365 days (or 366 days in a leap year) and shall be payable for the actual number of days elapsed (including the first day but excluding the last day). Any other fees payable to any Issuing Bank pursuant to this Section shall be payable within 10 days after demand.

-36-

(d) The Company agrees to pay (i) to the Administrative Agent, the Collateral Agent and the Lead Arrangers, for their own accounts, fees payable in the amounts and at the times separately agreed to pursuant to the Fee Letters and (ii) on or prior to the Effective Date, to the Administrative Agent for the account of each Lender an upfront fee in an amount separately agreed with the Lenders.

(e) All fees payable hereunder shall be paid on the dates due, in immediately available funds, to the Administrative Agent (or to each Issuing Bank, in the case of fees payable to it) for distribution (if applicable) to the Lenders as specified above. Fees paid shall not be refundable under any circumstances.

Section 2.11. Interest. (a) The Loans comprising each ABR Borrowing shall bear interest at the Alternate Base Rate plus the Applicable Rate.

(b) The Loans comprising each Eurodollar Borrowing shall bear interest at the Adjusted LIBO Rate for the Interest Period in effect for such Borrowing plus the Applicable Rate.

(c) Notwithstanding the foregoing, if any principal of or interest on any Loan or any fee or other amount payable by any Borrower hereunder is not paid when due, whether at stated maturity, upon acceleration or otherwise, such overdue amount shall bear interest, after as well as before judgment, at a rate per annum equal to (i) in the case of overdue principal of any Loan, 2% plus the rate otherwise applicable to such Loan as provided in the preceding paragraphs of this Section 2.11 or (ii) in the case of any other amount, 2% plus the rate applicable to ABR Loans as provided in paragraph (a) of this Section 2.11.

(d) Accrued interest on each Loan shall be payable in arrears on each Interest Payment Date for such Loan and upon termination of the Commitments; provided that (i) interest accrued pursuant to paragraph (c) of this Section 2.11 shall be payable on demand, (ii) in the event of any repayment or prepayment of any Loan, accrued interest on the principal amount repaid or prepaid shall be payable on the date of such repayment or prepayment and (iii) in the event of any conversion of any Eurodollar Loan prior to the end of the current Interest Period therefor, accrued interest on such Loan shall be payable on the effective date of such conversion.

(e) All interest hereunder shall be computed on the basis of a year of 360 days, except that interest computed by reference to the Alternate Base Rate at times when the Alternate Base Rate is based on the Prime Rate shall be computed on the basis of a year of 365 days (or 366 days in a leap year), and in each case shall be payable for the actual number of days elapsed (including the first day but excluding the last day of the Interest Period). The applicable Alternate Base Rate, Adjusted LIBO Rate or LIBO Rate shall be determined by the Administrative Agent, and such determination shall be conclusive absent manifest error.

Section 2.12. Alternate Rate of Interest; Illegality. (a) If prior to the commencement of any Interest Period for a Eurodollar Borrowing:

(i) the Administrative Agent determines in good faith (which determination shall be conclusive absent manifest error) that, by reason of circumstances generally affecting the London interbank Eurodollar market, adequate and reasonable means do not exist for ascertaining the Adjusted LIBO Rate or the LIBO Rate, as applicable, for such Interest Period; or

-37-

(ii) the Administrative Agent is advised by the Majority Lenders that the Adjusted LIBO Rate or the LIBO Rate, as applicable, for such Interest Period will not adequately and fairly reflect the cost to such Lenders of making or maintaining their Loans included in such Borrowing for such Interest Period;

then the Administrative Agent shall give notice thereof to the Borrowers and the Lenders by telephone or telecopy as promptly as practicable thereafter and, until the Administrative Agent notifies the Borrowers and the Lenders that the circumstances giving rise to such notice no longer exist, (x) any Interest Election Request that requests the conversion of any Borrowing to, or continuation of any Borrowing as, a Eurodollar Borrowing shall be ineffective, and (y) if any Borrowing Request requests a Eurodollar Borrowing, such Borrowing shall be made as an ABR Borrowing.

(b) If any Lender determines that any law, rule, regulation or order of any Governmental Authority has made it unlawful, or that any Governmental Authority has asserted that it is unlawful, for any Lender to make, maintain or fund Loans whose interest is determined by reference to the Adjusted LIBO Rate, or to determine or charge interest rates based upon the Adjusted LIBO Rate, or any Governmental Authority has imposed material restrictions on the authority of such Lender to purchase or sell, or to take deposits of, dollars in the London interbank market, then, on notice thereof by such Lender to the Borrowers through the Administrative Agent, (i) any obligation of such Lender to make or continue Eurodollar Loans or to convert ABR Loans to Eurodollar Loans shall be suspended, and (ii) if such notice asserts the illegality of such Lender making or maintaining ABR Loans the interest rate on which is determined by reference to the Adjusted LIBO Rate component of the Alternate Base Rate, the interest rate on which ABR Loans of such Lender shall, if necessary to avoid such illegality, be determined by the Administrative Agent without reference to the Adjusted LIBO Rate component of the Alternate Base Rate, in each case until such Lender notifies the Administrative Agent and the Borrowers that the circumstances giving rise to such determination no longer exist. Upon receipt of such notice, (x) each Borrower shall, upon demand from such Lender (with a copy to the Administrative Agent), prepay or, if applicable, convert all Eurodollar Loans of such Lender made to such Borrower to ABR Loans (the interest rate on which ABR Loans of such Lender shall, if necessary to avoid such illegality, be determined by the Administrative Agent without reference to the Adjusted LIBO Rate component of the Alternate Base Rate), either on the last day of the Interest Period therefor, if such Lender may lawfully continue to maintain such Eurodollar Loans to such day, or immediately, if such Lender may not lawfully continue to maintain such Eurodollar Loans and (y) if such notice asserts the illegality of such Lender determining or charging interest rates based upon the Adjusted LIBO Rate, the Administrative Agent shall during the period of such suspension compute the Alternate Base Rate applicable to such Lender without reference to the Adjusted LIBO Rate component thereof until the Administrative Agent is advised in writing by such Lender that it is no longer illegal for such Lender to determine or charge interest rates based upon the Adjusted LIBO Rate. Upon any such prepayment or conversion by a Borrower, such Borrower shall also pay accrued interest on the amount so prepaid or converted.

-38-

Section 2.13. Increased Costs.

(a) If any Change in Law shall:

(i) impose, modify or deem applicable any reserve, special deposit or similar requirement against assets of, deposits with or for the account of, or credit extended by, any Lender (except any such reserve requirement reflected in the Adjusted LIBO Rate) or any Issuing Bank;

(ii) impose on any Lender or any Issuing Bank or the London interbank market any other condition materially affecting this Agreement or Eurodollar Loans made by such Lender or any Letter of Credit or participation therein; or

(iii) subject any Lender or Issuing Bank to any Taxes (other than (A) Indemnified Taxes and (B) Excluded Taxes) on its loans, loan principal, letters of credit, commitments or other obligations, or its deposits, reserves, other liabilities or capital attributable thereto;

in each case other than as specified in paragraph (b) below, and the result of any of the foregoing shall be to increase the cost to such Lender of making or maintaining any Eurodollar Loan (or of maintaining its obligation to make any such Loan) or to increase the cost to such Lender or such Issuing Bank of participating in, issuing or maintaining any Letter of Credit or to reduce the amount of any sum received or receivable by such Lender or such Issuing Bank hereunder (whether of principal, interest or otherwise), in each case by an amount that such Lender or such Issuing Bank reasonably deems to be material, then the applicable Borrower or Borrowers will pay to such Lender or such Issuing Bank, as the case may be, in accordance with paragraph (c) of this Section 2.13 after such Borrower’s receipt of its written demand accompanied by documentation specifying in reasonable detail the events and circumstances and the applicable Change in Law in support of any such reimbursement request, such additional amount or amounts necessary to compensate such Lender or such Issuing Bank, as the case may be, for such additional costs incurred or reduction suffered.

(b) If any Lender or any Issuing Bank determines that any Change in Law regarding capital requirements has or would have the effect of reducing the rate of return on such Lender’s or such Issuing Bank’s capital or on the capital of such Lender’s or such Issuing Bank’s holding company, if any, as a consequence of this Agreement or the Loans made by, or participations in Letters of Credit held by, such Lender, or the Letters of Credit issued by such Issuing Bank, to a level below that which such Lender or such Issuing Bank or such Lender’s or such Issuing Bank’s holding company could have achieved but for such Change in Law (taking into consideration such Lender’s or such Issuing Bank’s policies and the policies of such Lender’s or such Issuing Bank’s holding company with respect to capital adequacy) by an amount reasonably deemed by such Lender or such Issuing Bank to be material, then from time to time upon submission by such Lender or such Issuing Bank to the applicable Borrower or Borrowers (with a copy to the Administrative Agent) of a written demand therefor accompanied by documentation specifying in reasonable detail the events and circumstances applicable to such reduction and the applicable Change in Law in support of such demand, and the amount demanded pursuant hereto, the applicable Borrower or Borrowers will, within 30 days after receipt of such demand, pay to such Lender or such Issuing Bank, as the case may be, such additional amount or amounts necessary to compensate such Lender or such Issuing Bank or such Lender’s or such Issuing Bank’s holding company for any such reduction suffered.

-39-

(c) A certificate of a Lender or such Issuing Bank setting forth the amount or amounts necessary to compensate such Lender or such Issuing Bank or its holding company, as the case may be, together with the relevant demand and accompanying documentation, all as specified in paragraph (a) or (b) of this Section 2.13, shall be delivered to the Company and shall be conclusive absent manifest error. The Company shall pay such Lender or such Issuing Bank, as the case may be, the amount shown as due on any such certificate within 30 days after receipt thereof.

(d) Failure or delay on the part of any Lender or any Issuing Bank to demand compensation pursuant to this Section 2.13 shall not constitute a waiver of such Lender’s or such Issuing Bank’s right to demand such compensation; provided that a Borrower shall not be required to compensate a Lender or an Issuing Bank pursuant to this Section for any increased costs or reductions incurred more than 180 days prior to the date that such Lender or such Issuing Bank, as the case may be, notifies the Company of the Change in Law giving rise to such increased costs or reductions and of such Lender’s or such Issuing Bank’s intention to claim compensation therefor in accordance with this Section; provided further that, if the Change in Law giving rise to such increased costs or reductions is retroactive, then the 180-day period referred to above shall be extended to include the period of retroactive effect thereof.

Section 2.14. Break Funding Payments. In the event of (a) the payment of any principal of any Eurodollar Loan other than on the last day of an Interest Period applicable thereto (including as a result of an Event of Default or any prepayment under Section 2.09(a) or Section 2.09(c)), (b) the conversion of any Eurodollar Loan other than on the last day of the Interest Period applicable thereto, (c) the failure to borrow, convert, continue or prepay any Eurodollar Loan on the date specified in any notice delivered pursuant hereto (regardless of whether such notice may be revoked under Section 2.09(b) and is revoked in accordance therewith), or (d) the assignment of any Eurodollar Loan other than on the last day of the Interest Period applicable thereto as a result of a request by a Borrower pursuant to Section 2.17, then, in any such event, such Borrower shall compensate each Lender for the loss, cost and expense attributable to such event. In the case of a Eurodollar Loan, such loss, cost or expense to any Lender shall be deemed to include an amount determined by such Lender to be the excess, if any, of (i) the amount of interest which would have accrued on the amount so prepaid or converted, or not so borrowed, continued, converted or prepaid, at the Adjusted LIBO Rate that would have been applicable to such Eurodollar Loan, for the period from the date of such event to the last day of the then current Interest Period therefor (or, in the case of a failure to borrow, convert or continue, for the Interest Period that would have commenced on the date of such failure for such Loan), over (ii) the amount of interest that would have accrued to such Lender on such principal amount for such period at the interest rate which such Lender would bid were it to bid, at the commencement of such period, for dollar deposits of a comparable amount and period from other banks in the interbank eurodollar market. A certificate of any Lender setting forth any amount or amounts that such Lender is entitled to receive pursuant to this Section shall be delivered to the applicable Borrower and shall be conclusive absent manifest error. Each affected Lender requesting payment under this Section shall submit written demand specifying in reasonable detail the events and circumstances resulting in such payment obligation, together with a certificate as to any amounts payable pursuant to this Section to the applicable Borrower. The applicable Borrower shall pay such Lender the amount shown as due on any such certificate within 30 days after receipt thereof.

-40-

Section 2.15. Taxes. (a) Any and all payments by or on account of any obligation of any Borrower hereunder shall be made free and clear of and without deduction for any Indemnified Taxes or Other Taxes; provided that if a Borrower shall be required to deduct any Indemnified Taxes or Other Taxes from such payments, then (i) the sum payable shall be increased as necessary so that after making all required deductions (including deductions applicable to additional sums payable under this Section) the Administrative Agent, Lender or Issuing Bank (as the case may be) receives an amount equal to the sum it would have received had no such deductions been made, (ii) such Borrower shall make such deductions, and (iii) such Borrower shall pay the full amount deducted to the relevant Governmental Authority in accordance with applicable law.

(b) In addition, each Borrower shall pay any Other Taxes to the relevant Governmental Authority in accordance with applicable law.

(c) Each Borrower shall indemnify the Administrative Agent, each Lender and each Issuing Bank, within 10 days after written demand therefor, for the full amount of any Indemnified Taxes or Other Taxes paid by the Administrative Agent, such Lender or such Issuing Bank, as the case may be, on or with respect to any payment by or on account of any obligation of any Borrower hereunder (including Indemnified Taxes or Other Taxes imposed or asserted on or attributable to amounts payable under this Section) and any penalties, interest and reasonable expenses arising therefrom or with respect thereto, whether or not such Indemnified Taxes or Other Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority. A certificate as to the amount of such payment or liability delivered to a Borrower by a Lender or an Issuing Bank, or by the Administrative Agent on its own behalf or on behalf of a Lender or an Issuing Bank, shall be conclusive absent manifest error.

(d) As soon as practicable after any payment of Indemnified Taxes or Other Taxes by a Borrower to a Governmental Authority, such Borrower 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) Any Foreign Lender that is entitled to an exemption from or a reduction of withholding tax under the law of the United States, or of the jurisdiction in which a Borrower is located, or any treaty to which such jurisdiction is a party, with respect to payments under this Agreement shall deliver to the Borrowers (with a copy to the Administrative Agent), at the time or times prescribed by applicable law, such properly completed and executed forms or other documentation prescribed by applicable law or reasonably requested by a Borrower as will permit such payments to be made without withholding or at a reduced rate. In addition, any Foreign Lender, if requested by any Borrower or the Administrative Agent, shall deliver such other documentation prescribed by applicable law or reasonably requested by any Borrower or the Administrative Agent as will enable the Borrowers or the Administrative Agent to determine whether or not such Foreign Lender is subject to backup withholding or information reporting requirements. Without limiting the generality of the foregoing, in the event that a Borrower is resident for tax purposes in the United States, any such Foreign Lender shall deliver to such Borrower and the Administrative Agent (in such number of copies as shall be reasonably requested by the recipient) on or prior to the date on which such Foreign Lender becomes a Lender under this Agreement (and from time to time thereafter upon the reasonable request of such Borrower or the Administrative Agent, but only if such Foreign Lender is legally entitled to do so), whichever of the following is applicable:

-41-

(i) duly completed copies of Internal Revenue Service Form W-8BEN claiming eligibility for benefits of an income tax treaty to which the United States is a party,

(ii) duly completed copies of Internal Revenue Service Form W-8ECI,

(iii) in the case of a Foreign Lender claiming the benefits of the exemption for portfolio interest under Section 881(c) of the Code, (x) a certificate substantially in the form of Exhibit G-1 or G-2, as applicable and (y) duly completed copies of Internal Revenue Service Form W-8BEN,

(iv) in the case of a payment made to a Lender under any Loan Document that 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 documentation prescribed by applicable law (including as prescribed by Section 1471(b)(3)(C)(i) of the Code) at the time or times prescribed by law and at such time or times reasonably requested by the Borrower or the Administrative Agent and such additional documentation reasonably requested by the Borrower or the Administrative Agent as may be necessary for the Borrower and the Administrative Agent to comply with their obligations under FATCA and 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, or

(v) any other form prescribed by applicable law as a basis for claiming exemption from or a reduction in United States Federal withholding tax duly completed together with such supplementary documentation as may be prescribed by applicable law to permit such Borrower to determine the withholding or deduction required to be made.

(f) The Administrative Agent or a Lender shall determine if, in its reasonable discretion, it has received a refund of any Indemnified Taxes or Other Taxes as to which it has been indemnified by a Borrower or with respect to which a Borrower has paid additional amounts pursuant to this Section 2.15. If it determines that it has received any such refund, it shall pay over such refund to such Borrower (but only to the extent of indemnity payments made, or additional amounts paid, by such Borrower under this Section 2.15 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 such Lender and without interest (other than any interest paid by the relevant Governmental Authority with respect to such refund); provided that each Borrower, upon the request of the Administrative Agent or such Lender, agrees to repay the amount paid over to such Borrower (plus any penalties, interest or other charges imposed by the relevant Governmental Authority) to the Administrative Agent or such Lender in the event the Administrative Agent or such Lender is required to repay such refund to such Governmental Authority. This Section shall not be construed to require the Administrative Agent or any Lender to make available its tax returns (or any other information relating to its taxes which it deems confidential) to any Borrower or any other Person.

-42-

Section 2.16. Payments Generally; Pro Rata Treatment; Sharing of Set-Offs. (a) Each Borrower shall make each payment required to be made by it hereunder and, unless stated otherwise therein, under any of the other Loan Documents (whether of principal, interest, fees or reimbursement of LC Disbursements, or of amounts payable under Section 2.13, Section 2.14, Section 2.15, or otherwise) prior to 12:00 noon, New York City time, on the date when due, in immediately available funds, without 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 at its offices at 270 Park Avenue, New York, New York, except payments to be made directly to an Issuing Bank as expressly provided herein and except that payments pursuant to Section 2.13, Section 2.14, Section 2.15 and Section 10.03 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 shall be made in dollars.

(b) Except as otherwise provided in Section 2.09(c), if at any time insufficient funds are received by and available to the Administrative Agent to pay fully all amounts of principal, unreimbursed LC Disbursements, interest and fees then due hereunder, such funds shall be applied (i) first, towards payment of interest and fees then due hereunder, ratably among the parties entitled thereto in accordance with the amounts of interest and fees then due to such parties, and (ii) second, towards payment of principal and unreimbursed LC Disbursements then due hereunder, ratably among the parties entitled thereto in accordance with the amounts of principal and unreimbursed LC Disbursements then due to such parties.

(c) If any Lender shall, by exercising any right of set-off or counterclaim or otherwise, obtain payment in respect of any principal of or interest on any of its Loans or participations in LC Disbursements resulting in such Lender receiving payment of a greater proportion of the aggregate amount of its Loans and participations in LC Disbursements 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 the Loans and participations in LC Disbursements 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 and participations in LC Disbursements; 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 shall not be construed to apply to any payment made by a Borrower pursuant to and in accordance with the express terms of this Agreement (including the application of funds arising from the existence of a Defaulting Lender) or any payment obtained by a Lender as consideration for the assignment of or sale of a participation in any of its Loans or participations in LC Disbursements to any assignee or participant, other than to a Borrower or any Subsidiary or Affiliate thereof (as to which the provisions of this paragraph shall apply). Each 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.

-43-

(d) Unless the Administrative Agent shall have received notice from a Borrower prior to the date on which any payment is due to the Administrative Agent for the account of the Lenders or any Issuing Bank hereunder that such Borrower will not make such payment, the Administrative Agent may assume that such Borrower has made such payment on such date in accordance herewith and may, in reliance upon such assumption, distribute to the Lenders or the applicable Issuing Bank, as the case may be, the amount due. In such event, if such Borrower has not in fact made such payment, then each of the Lenders or any applicable Issuing Bank, as the case may be, severally agrees to repay to the Administrative Agent forthwith on demand the amount so distributed to such Lender or such Issuing Bank, 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 or recovery by 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.

(e) If any Lender shall become a Defaulting Lender or shall fail to make any payment required to be made by it pursuant to Section 2.04(d), Section 2.04(e), Section 2.05(b), Section 2.16(d) or Section 10.03(c) and has not cured the payment within two Business Days, then the Administrative Agent shall, unless the Administrative Agent determines that such application entails a material risk of violation of applicable law or order and notwithstanding any contrary provision hereof, apply any amounts thereafter received by the Administrative Agent for the account of such Lender as follows: (i) first, to satisfy such Lender’s obligations under such Sections until all such unsatisfied obligations are fully paid, (ii) second, so long as no Default exists, to fund any Loan in respect of which that Lender has failed to fund its portion thereof as required by this Agreement, as determined by the Administrative Agent and (iii) third, to be held in a segregated account as cash collateral for, and application to, any future funding obligations of such Lender under any such Section. Any such cash collateral shall be returned to the Lender (x) if such Lender is a Defaulting Lender, once it ceases to be a Defaulting Lender or (y) upon termination of this Agreement; provided that, in each of clause (x) and (y), the Lender has made all payments required to be made hereunder.

Section 2.17. Mitigation Obligations; Replacement of Lenders. (a) If any Lender requests compensation under Section 2.13, or if any Borrower is required to pay any additional amount to any Lender or any Governmental Authority for the account of any Lender pursuant to Section 2.15, then such Lender shall use reasonable efforts to designate a different lending office for funding or booking its Loans hereunder or to assign its rights and obligations hereunder to another of its offices, branches or affiliates, if, in the judgment of such Lender, such designation or assignment (i) would eliminate or reduce amounts payable pursuant to Section 2.13 or, Section 2.15 as the case may be, in the future and (ii) would not subject such Lender to any unreimbursed cost or expense and would not otherwise be disadvantageous to such Lender. Each Borrower hereby agrees to pay all reasonable costs and expenses incurred by any Lender in connection with any such designation or assignment.

-44-

(b) If (w) any Lender requests compensation under Section 2.13, or (x) if any Borrower is required to pay any additional amount to any Lender or any Governmental Authority for the account of any Lender pursuant to Section 2.15, or (y) if any Lender is a Defaulting Lender or (z) any Lender refuses to grant its approval with respect to any matter requiring the approval of all Lenders and such matter shall have been approved by the Majority Lenders, then the Company may, at its sole expense and effort, upon notice to such Lender and the Administrative Agent, require such Lender to assign and delegate, without recourse (in accordance with and subject to the restrictions contained in Section 10.04), all its interests, rights and obligations under this Agreement to an assignee that shall assume such obligations (which assignee may be another Lender, if a Lender accepts such assignment); provided that (i) the Company shall have received the prior written consent of the Administrative Agent, which consent shall not unreasonably be withheld, (ii) such Lender shall have received payment of an amount equal to the outstanding principal of its Loans, participations in LC Disbursements, accrued interest thereon, accrued fees and all other amounts payable to it hereunder, from the assignee (to the extent of such outstanding principal, participations in LC Disbursements and accrued interest and fees) or the Borrowers (in the case of all other amounts) and (iii) in the case of any such assignment resulting from a claim for compensation under Section 2.13 or payments required to be made pursuant to Section 2.15, such assignment will result in a reduction in such compensation or payments. A Lender shall not be required to make any such assignment and delegation if, prior thereto, as a result of a waiver by such Lender or otherwise, the circumstances entitling the Company to require such assignment and delegation cease to apply.

Section 2.18. Defaulting Lenders. (a) Notwithstanding anything to the contrary contained in this Agreement, if any Lender becomes a Defaulting Lender, then, until such time as such Lender is no longer a Defaulting Lender, to the extent permitted by applicable law:

(i) Such Defaulting Lender’s right to approve or disapprove any amendment, waiver or consent with respect to this Agreement shall be restricted as set forth in Section 10.02.

(ii) Certain Fees.

(A) No Defaulting Lender shall be entitled to receive any fee described in Section 2.10(a) for any period during which that Lender is a Defaulting Lender (and the Borrowers shall not be required to pay any such fee that otherwise would have been required to have been paid to that Defaulting Lender).

(B) Each Defaulting Lender shall be entitled to receive fees described in Section 2.10(b) for any period during which it is a Defaulting Lender only to the extent allocable to the percentage of the stated amount of Letters of Credit for which it has provided Cash Collateral pursuant to Section 2.04(j).

-45-

(C) With respect to any fee described in Section 2.10(a) or (b) not required to be paid to any Defaulting Lender pursuant to clause (A) or (B) above, the Borrowers shall (x) pay to each Non-Defaulting Lender that portion of any such fee otherwise payable to such Defaulting Lender with respect to such Defaulting Lender’s participation in LC Exposure that has been reallocated to such Non-Defaulting Lender pursuant to clause (iii) below, (y) pay to the Issuing Bank the amount of any such fee otherwise payable to such Defaulting Lender to the extent allocable to the Issuing Bank’s Fronting Exposure to such Defaulting Lender, and (z) not be required to pay the remaining amount of any such fee.

(iii) All or any part of such Defaulting Lender’s participation in LC Exposure shall be reallocated among the Non-Defaulting Lenders in accordance with their respective Percentages (calculated without regard to such Defaulting Lender’s Commitment) but only to the extent that such reallocation does not cause any Non-Defaulting Lender’s Outstandings to exceed such Non-Defaulting Lender’s Commitment. No reallocation hereunder shall constitute a waiver or release of any claim of any party hereunder against a Defaulting Lender arising from that Lender having become a Defaulting Lender, including any claim of a Non-Defaulting Lender as a result of such Non-Defaulting Lender’s increased exposure following such reallocation.

(iv) If the reallocation described in clause (iii) above cannot, or can only partially, be effected, the Borrowers shall, without prejudice to any right or remedy available to it hereunder or under law, Cash Collateralize the Issuing Banks’ Fronting Exposure in accordance with the procedures set forth in Section 2.04(j).

(b) If the Borrowers, the Administrative Agent, and each Issuing Bank agree in writing that a Lender is no longer a Defaulting Lender, the Administrative Agent will so notify the parties hereto, whereupon as of the effective date specified in such notice and subject to any conditions set forth therein (which may include arrangements with respect to any Cash Collateral), that Lender will, to the extent applicable, purchase at par that portion of outstanding Loans of the other Lenders or take such other actions as the Administrative Agent may determine to be necessary to cause the Loans and funded and unfunded participations in Letters of Credit to be held pro rata by the Lenders in accordance with the Commitments (without giving effect to Section 2.18(a)(iii)), whereupon such Lender will cease to be a Defaulting Lender; provided that no adjustments will be made retroactively with respect to fees accrued or payments made by or on behalf of the Borrowers while that Lender was a Defaulting Lender; and provided, further, that except to the extent otherwise expressly agreed by the affected parties, no change hereunder from Defaulting Lender to Lender will constitute a waiver or release of any claim of any party hereunder arising from that Lender’s having been a Defaulting Lender.

(c) So long as any Lender is a Defaulting Lender, no Issuing Bank shall be required to issue, extend, renew or increase any Letter of Credit unless it is satisfied that it will have no Fronting Exposure after giving effect thereto.

-50-

Section 4.01. Organization; Powers. The Company is a Business Entity duly formed, validly existing and in good standing under the laws of the State of Delaware. Each other Credit Related Party is duly organized or formed, validly existing and, if applicable, in good standing in the jurisdiction of its organization or formation. Each Credit Related Party possesses all applicable Business Entity powers and all other authorizations and licenses necessary to engage in its business and operations as now conducted, the failure to obtain or maintain which would have a Material Adverse Effect.

Section 4.02. Authorization. The execution, delivery and performance by each Credit Party of the Loan Documents to which it is a party are within such Credit Party’s applicable Business Entity powers, have been duly authorized by all necessary applicable Business Entity action, and do not contravene (a) any Credit Related Party’s organizational documents, or (b) any law or any material contractual restriction binding on or affecting any Credit Related Party.

Section 4.03. Governmental Approvals; No Conflicts. No authorization or approval or other action by, and no notice to or filing with, any Governmental Authority is required for the due execution, delivery and performance by any Credit Party of any Loan Document to which it is a party, except those necessary to comply with laws, rules, regulations and orders required in the ordinary course to comply with ongoing obligations of such Credit Party under Section 5.01, Section 5.02 and Section 5.07, as applicable.

Section 4.04. Binding Obligation; Enforceability. This Agreement constitutes, and the other Loan Documents when delivered hereunder shall constitute, the legal, valid and binding obligations of each Credit Party that is a party thereto, enforceable against such Credit Party in accordance with their respective terms, except as may be limited by any applicable bankruptcy, insolvency, reorganization, moratorium or similar laws affecting creditors’ rights generally or by general principles of equity.

Section 4.05. Financial Condition.

(a) The consolidated balance sheet of the Company and its consolidated Subsidiaries as of December 31, 2010, and the related consolidated statements of income and cash flows of the Company and its consolidated Subsidiaries for the fiscal year then ended, reported on by Ernst & Young LLP, independent public accountants, copies of which have been furnished to the Administrative Agent and the Lenders prior to the date hereof, present fairly, in all material respects, the consolidated financial condition of the Company and its consolidated Subsidiaries as at such date and the consolidated results of the operations of the Company and its consolidated Subsidiaries for the period ended on such date, all in accordance with GAAP consistently applied (except as approved by the chief financial officer of such entity and as disclosed therein).

(b) The consolidated balance sheets of the Company and its consolidated Subsidiaries as of March 31, 2011, and the related consolidated statements of income and cash flows of the Company and its consolidated Subsidiaries for the fiscal period then ended, copies of which have been furnished to the Administrative Agent on or prior to the date hereof, present fairly, in all material respects, the consolidated financial condition of the Company and its consolidated Subsidiaries as at such date and the consolidated results of the operations of the Company and its consolidated Subsidiaries for the period ended on such date, all in accordance with GAAP consistently applied (except as approved by the chief financial officer of such entity and as disclosed therein), subject in the case of such unaudited statements to normal year-end audit adjustments and reduced footnote disclosure.

-51-

(c) Except as set forth in Schedule 4.05 or in the annual and quarterly reports referred to in Section 4.07 (collectively, the “Disclosure Update”), as of the Effective Date, since December 31, 2010, there has been no Material Adverse Effect.

Section 4.06. Compliance with Laws and Agreements. Each of the Company and its Subsidiaries is in compliance with all laws, rules, regulations and orders of any Governmental Authority applicable to it or its property except where the failure to comply, individually or in the aggregate, would not, in the reasonable judgment of the Company, be expected to result in a Material Adverse Effect; provided that the alleged failures to comply with such laws, rules, regulations, and orders that are disclosed in any annual report on Form 10-K, quarterly report on Form 10-Q or current report on Form 8-K filed by any Borrower with the SEC prior to the Effective Date shall not be expected to have a Material Adverse Effect for any purposes hereof.

Section 4.07. Litigation. There is no action, suit or proceeding pending, or to the knowledge of any Borrower threatened, against or involving any Credit Related Party in any court, or before any arbitrator of any kind, or before or by any Governmental Authority, existing as of the Effective Date (x) that in the reasonable judgment of the Company (taking into account the availability of appeals) could reasonably be expected to have a Material Adverse Effect, except for the proceedings described in the Company’s annual report on Form 10-K for the year ended December 31, 2010 or its quarterly report on Form 10-Q for the fiscal quarter ended March 31, 2011 (the “1st Quarter 2011 10-Q”) as filed with the SEC (the “Disclosed Proceedings”) or (y) which purports to affect the legality, validity, binding effect or enforceability of the Loan Documents. Since the date of filing of the 1st Quarter 2011 10-Q, there has been no adverse change in the status of the Disclosed Proceedings that, taking into account the availability of any appeals, could reasonably be expected to increase materially the likelihood of a Material Adverse Effect resulting therefrom.

Section 4.08. Taxes. Each Credit Related Party has duly filed all tax returns required to be filed by it, and has duly paid and discharged all taxes, assessments and governmental charges upon it or against its properties now due and payable, the failure to file or pay which, as applicable, would have a Material Adverse Effect, unless and to the extent only that the same are being contested in good faith and by appropriate proceedings by the Company or the applicable Credit Related Party.

Section 4.09. Properties. (a) Each Credit Related Party has good title to its respective properties and assets, free and clear of all mortgages, liens and encumbrances, except for (i) Transaction Liens and (ii) other mortgages, liens and other encumbrances (including covenants, restrictions, rights, easements and minor irregularities in title) that do not materially interfere with the business or operations of such Credit Related Party as presently conducted or that are permitted by Section 6.01.

(b) As of the Effective Date, the Company is aware of no Liens permitted by Section 6.01(a) solely by reason of clause (d) of the definition of Collateral Permitted Liens.

-52-

Section 4.10. ERISA. (a) No Termination Event has occurred or is reasonably expected to occur with respect to any Plan which, with the giving of notice or lapse of time, or both, would constitute an Event of Default under paragraph (h) of ARTICLE 7.

(b) Each Plan has complied with the applicable provisions of ERISA and the Code where the failure to so comply would reasonably be expected to result in a Material Adverse Effect.

(k) Unless the Collateral Release Date shall have occurred, any Security Document shall for any reason fail or cease to create a valid and enforceable Lien on any Collateral stated to be covered thereby or, except as permitted by the Loan Documents, such Lien shall fail or cease to be a perfected and first-priority (subject only to Collateral Permitted Liens) Lien, or any Credit Related Party shall so state in writing and, if such invalidity or lack of perfection or priority relates solely to Collateral with an aggregate value of $1,000,000 or less and such invalidity or lack of perfection or priority is such so as to be amenable to cure without material disadvantage to the position of the Administrative Agent, the Collateral Agent and the other Secured Parties, such invalidity or lack of perfection or priority shall not be cured within 10 days of the earlier of such Credit Related Party so stating in writing or delivery of notice thereof by the Administrative Agent to the Company (or such shorter period as shall be specified by the Administrative Agent and is reasonable under the circumstances);

-67-

then, and in every such event (other than an event with respect to any Credit Related Party described in paragraph (f) of this Article except for clause (i)(A) thereof), and at any time thereafter during the continuance of such event, the Administrative Agent may, and at the request of the Majority Lenders shall, by notice to the Company, take either or both of the following actions, at the same or different times: (i) declare the Commitments to be terminated and thereupon the Commitments shall terminate immediately, and (ii) declare the Loans and the Notes then outstanding, all interest thereon and all other amounts payable under this Agreement to be forthwith due and payable in whole (or in part, in which case any principal not so declared to be due and payable may thereafter be declared to be due and payable), and thereupon the principal of the Loans so declared to be due and payable together with accrued interest thereon and all fees and other obligations of the Borrowers accrued hereunder, shall become due and payable immediately, without presentment, demand, protest or further notice of any kind, all of which are hereby expressly waived by the Borrowers; provided, however, that if an Event of Default under paragraph (f) (except under clause (i)(A) thereof) shall occur, (A) the Commitments shall automatically terminate and (B) the principal of the Loans and the Notes then outstanding, together with accrued interest thereon and all fees and other obligations of the Borrowers accrued hereunder shall automatically become due and payable, without presentment, demand, protest or any notice of any kind, all of which are hereby expressly waived by the Borrowers.

ARTICLE 8

Company Guarantee

Section 8.01. Company Guarantee.

(a) The Company hereby unconditionally and irrevocably guarantees to the Collateral Agent, for the ratable benefit of the Secured Parties and each of their respective permitted successors, endorsees, transferees and assigns, (i) the prompt and complete payment by the Pipeline Company Borrowers when due (whether at the stated maturity, by acceleration or otherwise) of the Obligations payable by any of them and (ii) the prompt and complete payment by the Subsidiary Guarantors when due (whether at the stated maturity, by acceleration or otherwise) of all amounts payable by them under the Subsidiary Guarantee Agreement (the obligations described in the foregoing clauses (i) and (ii) being herein referred to as the “Company Guaranteed Obligations”). This is a guarantee of payment and not collection and the liability of the Company is primary and not secondary.

(b) The guarantee contained in this ARTICLE 8 shall remain in full force and effect until the Final Payment Date, notwithstanding that from time to time during the term of this Agreement, no Company Guaranteed Obligations may be outstanding.

-68-

(c) No payment made by any Pipeline Company Borrower, any of the Subsidiary Guarantors, any other guarantor or any other Person, or received or collected by any Agent or any Lender from any Pipeline Company Borrower, any of the Subsidiary Guarantors, any other guarantor or any other Person, by virtue of any action or proceeding or any set-off or appropriation or application at any time or from time to time in reduction of or in payment of the Obligations shall be deemed to modify, reduce, release or otherwise affect the liability of the Company hereunder which shall, notwithstanding any such payment (other than any payment made by the Company in respect of the Company Guaranteed Obligations or any payment received or collected from the Company in respect of the Company Guaranteed Obligations), remain liable for the Company Guaranteed Obligations until the Final Payment Date.

Section 8.02. No Subrogation. Notwithstanding any payment made by any Pipeline Company Borrower hereunder, the Company under this ARTICLE 8 or any Subsidiary Guarantor under the Subsidiary Guarantee Agreement or any set-off or application of funds of any Pipeline Company Borrower or any Subsidiary Guarantor by any Agent or any Lender, the Company shall not be entitled to be subrogated to any of the rights of any Agent or any Lender against any Pipeline Company Borrower or any Subsidiary Guarantor or any collateral security or guarantee or right of offset held by any Agent or any Lender for the payment of the Company Guaranteed Obligations, nor shall the Company seek or be entitled to seek any contribution or reimbursement from any Pipeline Company Borrower or any Subsidiary Guarantor in respect of payments made by the Company hereunder, until the Final Payment Date. If any amount shall be paid to the Company on account of such subrogation rights prior to the Final Payment Date, such amount shall be held by the Company in trust for the Agents and the Lenders, segregated from other funds of the Company, and shall, forthwith upon receipt by the Company, be turned over to the Administrative Agent in the exact form received by the Company (duly indorsed by the Company to the Administrative Agent, if required), to be applied against the Company Guaranteed Obligations, whether matured or unmatured), in such order as the Administrative Agent may determine but subject in any event to the terms and provisions of this Agreement and the Security Agreement.

Section 8.03. Amendments, etc. with Respect to the Obligations. The Company shall remain obligated hereunder notwithstanding that, without any reservation of rights against the Company and without notice to or further assent by the Company, any demand for payment of any of the Company Guaranteed Obligations made by any Agent or any Lender may be rescinded by such Agent or such Lender and any of the Company Guaranteed Obligations continued, and the Company Guaranteed Obligations, or the liability of any other Person upon or for any part thereof, or any collateral security or guarantee therefor or right of offset with respect thereto, may, from time to time, in whole or in part, be renewed, extended, amended, modified, accelerated, compromised, waived, surrendered or released by any Agent or any Lender, and this Agreement and the other Loan Documents and any other documents executed and delivered in connection therewith may be amended, modified, supplemented or terminated, in whole or in part, as the Administrative Agent (or the Majority Lenders or all Lenders, as the case may be) may deem advisable from time to time, and any collateral security, guarantee or right of offset at any time held by any Agent or any Lender for the payment of the Company Guaranteed Obligations may be sold, exchanged, waived, surrendered or released. Neither the Administrative Agent, the Collateral Agent nor any Lender or other Secured Party shall have any obligation to protect, secure, perfect or insure any Lien at any time held by it as security for the Company Guaranteed Obligations or for the guarantee contained in this ARTICLE 8 or any property subject thereto.

-69-

Section 8.04. Guarantee Absolute and Unconditional. The Company waives any and all notice of the creation, renewal, extension or accrual of any of the Company Guaranteed Obligations and notice of or proof of reliance by any Agent or any Lender upon the guarantee contained in this ARTICLE 8 or acceptance of the guarantee contained in this ARTICLE 8; the Company Guaranteed Obligations, and any of them, shall conclusively be deemed to have been created, contracted or incurred, or renewed, extended, amended or waived, in reliance upon the guarantee contained in this ARTICLE 8; and all dealings between the Company, any of the Pipeline Company Borrowers and any Subsidiary Guarantor, on the one hand, and the Agents and the Lenders, on the other hand, likewise shall be conclusively presumed to have been had or consummated in reliance upon the guarantee contained in this ARTICLE 8. The Company waives diligence, presentment, protest, demand for payment and notice of default or nonpayment to or upon the Pipeline Company Borrowers or any of the Subsidiary Guarantors with respect to the Company Guaranteed Obligations. The Company understands and agrees that the guarantee contained in this ARTICLE 8 shall be construed as a continuing, absolute and unconditional guarantee of payment without regard to (a) the validity or enforceability of this Agreement or any other Loan Document, any of the Company Guaranteed Obligations or any other collateral security therefor or guarantee or right of offset with respect thereto at any time or from time to time held by any Agent or any Lender, (b) any defense, set-off or counterclaim (other than a defense of payment or performance) which may at any time be available to or be asserted by any Pipeline Company Borrower, any Subsidiary Guarantor or any other Person against any Agent or any Lender, or (c) any other circumstance whatsoever (with or without notice to or knowledge of the Pipeline Company Borrowers, the Subsidiary Guarantors or the Company), other than payment or performance, which constitutes, or might be construed to constitute, an equitable or legal discharge of Pipeline Company Borrowers or the Subsidiary Guarantors for the Company Guaranteed Obligations, or of the Company under the guarantee contained in this ARTICLE 8, in bankruptcy or in any other instance. When making any demand hereunder or otherwise pursuing its rights and remedies hereunder against the Company, any Agent or any Lender may, but shall be under no obligation to, make a similar demand on or otherwise pursue such rights and remedies as it may have against any Pipeline Company Borrower, any Subsidiary Guarantor or any other Person or against any collateral security or guarantee for the Company Guaranteed Obligations or any right of offset with respect thereto, and any failure by any Agent or any Lender to make any such demand, to pursue such other rights or remedies or to collect any payments from any Pipeline Company Borrower, any Subsidiary Guarantor or any other Person or to realize upon any such collateral security or guarantee or to exercise any such right of offset, or any release of any Pipeline Company Borrower, any Subsidiary Guarantor or any other Person or any such collateral security, guarantee or right of offset, shall not relieve the Company of any obligation or liability hereunder, and shall not impair or affect the rights and remedies, whether express, implied or available as a matter of law, of any Agent or any Lender against the Company. For the purposes hereof “demand” shall include the commencement and continuance of any legal proceedings.

Section 8.05. Reinstatement. The guarantee contained in this ARTICLE 8shall continue to be effective, or be reinstated, as the case may be, if at any time payment, or any part thereof, of any of the Company Guaranteed Obligations is rescinded or must otherwise be restored or returned by any Agent or any Lender upon the insolvency, bankruptcy, dissolution, liquidation or reorganization of the Company, any Pipeline Company Borrower or any Subsidiary Guarantor, or upon or as a result of the appointment of a receiver, intervenor or conservator of, or trustee or similar officer for, the Company, any Pipeline Company Borrower or any Subsidiary Guarantor or any substantial part of its or their respective property, or otherwise, all as though such payments had not been made.

-70-

ARTICLE 9

The Agents

Each of the Lenders and each Issuing Bank hereby irrevocably appoints each of the Administrative Agent and the Collateral Agent as its agent and authorizes each of the Administrative Agent and the Collateral Agent to take such actions on its behalf and to exercise such powers as are delegated to the Administrative Agent and the Collateral Agent by the terms hereof and of the other Loan Documents, together with such actions and powers as are reasonably incidental thereto.

Any bank 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 such bank and its Affiliates may accept deposits from, lend money to and generally engage in any kind of business with the Borrowers or any Subsidiary or other Affiliate thereof as if it were not an Agent hereunder.

No Agent shall not have any duties or obligations except those expressly set forth herein or in the Security Agreement. Without limiting the generality of the foregoing, (a) no Agent shall be subject to any fiduciary or other implied duties, regardless of whether a Default has occurred and is continuing, (b) no Agent shall have any duty to take any discretionary action or exercise any discretionary powers, except discretionary rights and powers expressly contemplated hereby that such Agent is required to exercise in writing as directed by the Majority Lenders (or such other number or percentage of the Lenders as shall be necessary under the circumstances as provided in Section 10.02); 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, including for the avoidance of doubt any action that may be in violation of the automatic stay under any Debtor Relief Law or that may effect a forfeiture, modification or termination of property of a Defaulting Lender in violation of any Debtor Relief Law, and (c) except as expressly set forth herein, no Agent shall have any duty to disclose, and shall not be liable for the failure to disclose, any information relating to the Borrowers or any of their Subsidiaries that is communicated to or obtained by the bank serving as an Agent or any of its Affiliates in any capacity. No Agent shall be liable for any action taken or not taken by it with the consent or at the request of the Majority Lenders (or such other number or percentage of the Lenders as shall be necessary under the circumstances as provided in Section 10.02) or in the absence of its own gross negligence or willful misconduct. No Agent shall be deemed to have knowledge of any Default unless and until written notice thereof is given to such Agent by a Borrower or a Lender, and no Agent 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, (ii) the contents of any certificate, report or other document delivered hereunder or in connection herewith, (iii) the performance or observance of any of the covenants, agreements or other terms or conditions set forth herein, (iv) the validity, enforceability, effectiveness or genuineness of this Agreement or any other agreement, instrument or document, or (v) the satisfaction of any condition set forth in ARTICLE 3 or elsewhere herein, other than to confirm receipt of items expressly required to be delivered to the Administrative Agent.

-71-

Each 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 believed by it to be genuine and to have been signed or sent by the proper Person. Each Agent also may rely upon any statement made to it orally or by telephone and believed by it to be made by the proper Person, and shall not incur any liability for relying thereon. Each Agent may consult with legal counsel (who may be counsel for a Credit Party), 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.

Any Agent may perform any and all its duties and exercise its rights and powers by or through any one or more sub-agents appointed by such Agent. Any Agent and any such sub-agent may perform any and all its duties and exercise its rights and powers through their respective Related Parties. The exculpatory provisions of the preceding paragraphs shall apply to any such sub-agent and to the Related Parties of any Agent and any such sub-agent, 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.

Subject to the appointment and acceptance of a successor Administrative Agent or Collateral Agent as provided in this paragraph, each of the Administrative Agent and the Collateral Agent may resign at any time by notifying the Lenders, each Issuing Bank and the Company. Upon any such resignation, the Majority Lenders shall have the right, in consultation with the Company, to appoint a successor. If no successor shall have been so appointed by the Majority Lenders and shall have accepted such appointment within 30 days after the retiring Agent gives notice of its resignation, then the retiring Agent may, on behalf of the Lenders and each Issuing Bank, appoint a successor Agent which shall be a bank with an office in New York, New York, or an Affiliate of any such bank. Upon the acceptance of its appointment as Administrative Agent or Collateral Agent hereunder by a successor, such successor shall succeed to and become vested with all the rights, powers, privileges and duties of the retiring Agent, and the retiring Agent shall be discharged from its duties and obligations hereunder. The fees payable by the Borrowers to a successor Agent shall be the same as those payable to its predecessor unless otherwise agreed between the Company and such successor. After an Agent’s resignation hereunder, the provisions of this Article and Section 10.03 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 it was acting as Administrative Agent or Collateral Agent.

If the Person serving as Administrative Agent or Collateral Agent is a Defaulting Lender pursuant to clause (d) of the definition thereof, the Majority Lenders may, to the extent permitted by applicable law, by notice in writing to the Borrowers and such Person remove such Person as Administrative Agent or Collateral Agent, as applicable, and, in consultation with the Borrowers, appoint a successor. If no such successor shall have been so appointed by the Majority Lenders and shall have accepted such appointment within 30 days (or such earlier day as shall be agreed by the Majority Lenders and the Borrowers) (the “Removal Effective Date”), then such removal shall nonetheless become effective in accordance with such notice on the Removal Effective Date.

-72-

Each Lender acknowledges that it has, independently and without reliance upon any Agent or any other Lender 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 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 related agreement or any document furnished hereunder or thereunder.

Section 10.02. Waivers; Amendments. (a) No failure or delay by any Agent, any Issuing Bank or any Lender in exercising any right or power hereunder shall operate as a waiver thereof, nor shall any single or partial exercise of any such right or power, or any abandonment or discontinuance of steps to enforce such a right or power, preclude any other or further exercise thereof or the exercise of any other right or power. The rights and remedies of the Agents, each Issuing Bank and the Lenders hereunder 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 consent to any departure by any Borrower therefrom shall in any event be effective unless the same shall be permitted by paragraph (b) of this Section, and then such waiver or consent shall be effective only in the specific instance and for the purpose for which given. Without limiting the generality of the foregoing, the making of a Loan or issuance of a Letter of Credit shall not be construed as a waiver of any Default, regardless of whether any Agent, any Lender or any Issuing Bank may have had notice or knowledge of such Default at the time.

(b) Except as expressly provided herein or in the applicable Loan Document, no provision of this Agreement or any other Loan Document may be waived, amended or modified, and no consent may be granted with respect to any departure by the Administrative Agent, any Lender or any Credit Party with respect hereto or thereto, except pursuant to an agreement or agreements in writing entered into by the Borrowers and the Majority Lenders or by the Borrowers and the Administrative Agent with the consent of the Majority Lenders; provided that no such waiver, amendment or modification of this Agreement or any other Loan Document, and no consent with respect to any departure by the Administrative Agent, any Lender, or any Credit Party with respect hereto or thereto, shall:

(i) increase the Commitment of any Lender, without the written consent of such Lender;

(ii) reduce or forgive the principal amount of any Loan or LC Disbursement or reduce the rate of interest thereon, or reduce any fees payable hereunder, without the written consent of each Lender affected thereby;

(iii) postpone the scheduled date of payment of the principal amount of any Loan or LC Disbursement, or any interest thereon, or any fees payable hereunder, or reduce the amount of, waive or excuse any such payment, or postpone the scheduled date of expiration of any Commitment, without the written consent of each Lender affected thereby;

(iv) issue any Letter of Credit with an expiration date, or extend the expiration date of any Letter of Credit to a date, that is later than the fifth Business Days prior to the Revolving Maturity Date, without the written consent of each Lender and the Issuing Bank of such Letter of Credit;

-75-

(v) change Section 2.16(b) or Section 2.16(c) in a manner that would alter the pro rata sharing of payments required thereby, without the written consent of each Lender;

(vi) release any Subsidiary Guarantor from its obligations under the Subsidiary Guarantee Agreement, without the written consent of each Lender, except in connection with the Disposition or merger of such Subsidiary Guarantor that is otherwise permitted hereunder;

(vii) release the Company from its guarantee obligations under ARTICLE 8, without the written consent of each Lender;

(viii) release all or substantially all of the Collateral if the Collateral Release Date has not occurred, without the written consent of each Lender except in connection with a merger involving, or Disposition of, a Subsidiary Guarantor or a Pipeline Company Borrower as permitted hereunder; or

(ix) change any of the provisions of this Section or the definitions of “Majority 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 written consent of each Lender;

provided further that no such agreement shall amend, modify or otherwise affect the rights or duties of any Agent or any Issuing Bank hereunder or under any other Loan Document without the prior written consent of such Agent or such Issuing Bank, as the case may be. Any such waiver and any such amendment or modification shall apply equally to each of the Lenders and shall be binding upon the Borrowers, the Lenders, the Issuing Banks and the Agents. In the case of any waiver, the Borrowers, the Lenders, the Issuing Banks and the Agents shall be restored to their former position and rights hereunder and under the other Loan Documents, and any Default or Event of Default waived shall be deemed waived ab initio and not continuing unless such waiver expressly provides otherwise; but no such waiver shall extend to any subsequent or other Default or Event of Default. Notwithstanding anything to the contrary herein, no Defaulting Lender shall have any right to approve or disapprove any amendment, waiver or consent hereunder (and any amendment waiver or consent which by its terms requires the consent of all Lenders or each affected Lender may be effected with the consent of the Lenders other than Defaulting Lenders), except that (x) the Commitment of any Defaulting Lender may not be increased or extended, nor the principal amount of any Loan owed to such Defaulting Lender reduced or the final maturity thereof extended, without the consent of such Defaulting Lender, (y) any waiver, amendment or modification requiring the consent of all Lenders or each affected Lender that by its terms affects any Defaulting Lender more adversely than other affected Lenders shall require the consent of such Defaulting Lender, and (z) any waiver, amendment or modification changing the voting rights of a Defaulting Lender shall require the consent of each Lender, including the Defaulting Lender.

Section 10.03. Expenses; Indemnity; Damage Waiver. (a) The Company shall pay (i) all reasonable out-of-pocket expenses incurred by the Administrative Agent and its Affiliates, including the reasonable fees, charges and disbursements of counsel for the Administrative Agent, in connection with the syndication of the credit facilities provided for herein, the preparation and administration of this Agreement or any amendments, modifications or waivers of the provisions hereof (whether or not the transactions contemplated hereby or thereby shall be consummated), (ii) all reasonable out-of-pocket expenses incurred by any Issuing Bank in connection with the issuance, amendment, renewal or extension of any Letter of Credit by it or any demand for payment thereunder made by such Issuing Bank (unless included in the fees charged separately by such Issuing Bank in respect of such Letter of Credit) and (iii) all out-of-pocket expenses incurred by any Agent, any Issuing Bank or any Lender, including the fees, charges and disbursements of any counsel for the Administrative Agent, any Issuing Bank, and during the continuation of any Default any other Agent or any Lender, in connection with the enforcement or protection of its rights in connection with this Agreement, including its rights under this Section, or in connection with the Loans made or Letters of Credit issued hereunder, including all such out-of-pocket expenses incurred during any workout, restructuring or negotiations in respect of such Loans or Letters of Credit.

(b) Each of the Borrowers shall indemnify, without duplication, each Agent, each Issuing Bank and each Lender, and each Related Party of any of the foregoing Persons (each such Person being called an “Indemnitee”) against, and hold each Indemnitee harmless from, any and all losses, claims, damages, liabilities and related expenses, including the fees, charges and disbursements of any counsel for any Indemnitee, incurred by or asserted against any Indemnitee arising out of, in connection with, or as a result of (i) the execution or delivery of this Agreement or any agreement or instrument contemplated hereby, the performance by the parties hereto of their respective obligations hereunder or the consummation of the Transactions or any other transactions contemplated hereby, (ii) any Loan or Letter of Credit or the use of the proceeds therefrom (including any refusal by the applicable Issuing Bank to honor a demand for payment under a Letter of Credit issued by it in accordance with applicable law if the documents presented in connection with such demand do not strictly comply with the terms of such Letter of Credit), (iii) any actual or alleged presence or release of Hazardous Materials on or from any property owned or operated by the Company or any of its Subsidiaries, or any Environmental Liability related in any way to the Company or any of its Subsidiaries, or (iv) any actual or prospective claim, litigation, investigation or proceeding relating to any of the foregoing, whether based on contract, tort or any other theory and regardless of whether any Indemnitee is a party thereto, IN ALL CASES, WHETHER OR NOT CAUSED BY OR ARISING, IN WHOLE OR IN PART, OUT OF THE COMPARATIVE, CONTRIBUTORY OR SOLE NEGLIGENCE OF THE INDEMNITEE; provided that such indemnity shall not, in any of the foregoing circumstances as to any Indemnitee, be available to the extent that such losses, claims, damages, liabilities or related expenses (x) are determined by a court of competent jurisdiction by final and nonappealable judgment to have resulted from or to have been attributable to the gross negligence or willful misconduct of such Indemnitee or (y) have arisen from a dispute between or among the Arrangers, the Administrative Agent or the Lenders or from a claim of an Indemnitee against another Indemnitee which in either case is not a direct or indirect result of any act or omission of the Borrowers or any of their subsidiaries. The indemnification provisions of this Section 10.03(b) are not intended to constitute a guaranty of payment of any principal, interest, facility or commitment fees, rental or other lease payments, or analogous amounts, under the Loans or any other Secured Obligations; provided that nothing in this Section 10.03(b) shall limit the liability of any Borrower for the payment of the Loans or any Secured Obligations, which liability arises under any other Loan Document, including any liability arising under this Agreement.

-77-

(c) To the extent that any Borrower fails to pay any amount required to be paid by it to any Agent or any Issuing Bank under paragraph (a) or (b) of this Section, each Lender severally agrees to pay to such Agent or such Issuing Bank, as the case may be, such Lender’s pro rata share (determined as of the time that the applicable unreimbursed expense or indemnity payment is sought based on the Commitments at such time, or if the Commitments have terminated or expired, based on the Credit Exposures at such time) of such unpaid amount; provided that the unreimbursed expense or indemnified loss, claim, damage, liability or related expense, as the case may be, was incurred by or asserted against such Agent or such Issuing Bank in its capacity as such.

(d) To the extent permitted by applicable law, the Borrowers shall not and each Indemnitee, by its acceptance of any right to or benefit of indemnification under this Agreement and as a condition to its rights to and benefits of indemnification provided for herein, agrees that it shall not, assert, and hereby waives, any claim against any Indemnitee or any Borrower, respectively, on any theory of liability, for special, indirect, consequential or punitive damages (as opposed to direct or actual damages) arising out of, in connection with, or as a result of, this Agreement or any agreement or instrument contemplated hereby, the Transactions, any Loan or Letter of Credit or the use of the proceeds thereof.

(e) All amounts due under this Section shall be payable not later than 30 days after the delivery of written demand to the Company therefor.

Section 10.04. Successors and Assigns. (a) The provisions of this Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns permitted hereby (including any Affiliate of an Issuing Bank that issues any Letter of Credit), except that (i) the Borrowers may not assign or otherwise transfer any of their respective rights or obligations hereunder in a transaction not permitted hereunder without the prior written consent of each Lender (and any attempted assignment or transfer by any Borrower without such consent shall be null and void), and (ii) no Lender may assign or otherwise transfer its rights or obligations hereunder except in accordance with this Section. Nothing in this Agreement, expressed or implied, shall be construed to confer upon any Person (other than the parties hereto, their respective successors and assigns permitted hereby (including any Affiliate of an Issuing Bank that issues any Letter of Credit), Participants (to the extent provided in paragraph (c) of this Section) and, to the extent expressly contemplated hereby, the Related Parties of each of the Administrative Agent, each Issuing Bank and the Lenders) any legal or equitable right, remedy or claim under or by reason of this Agreement.

(b) (i) Subject to the conditions set forth in paragraph (b)(ii) below, any Lender may assign to one or more assignees all or a portion of its rights and obligations under this Agreement (including all or a portion of its Commitment and its Loans (if any)) with the prior written consent (such consent not to be unreasonably withheld or delayed) of:

-78-

(A) the Company, provided that no consent of the Company shall be required for an assignment to a Lender, an Affiliate of a Lender, an Approved Fund (as defined below) or, if an Event of Default has occurred and is continuing, any other assignee; and

(B) the Administrative Agent; and

(ii) Assignments shall be subject to the following additional conditions:

(A) except (i) in the case of an assignment to a Lender or an Affiliate of a Lender or an Approved Fund or an assignment of the entire remaining amount of the assigning Lender’s Commitment (or, if the applicable Commitment is not then in effect, the outstanding principal balance of the Loans of the assigning Lender subject to each such assignment) or (ii) if each of the Company (unless an Event of Default has occurred and is continuing) and the Administrative Agent otherwise consent, the amount of the Commitment (or, if the applicable Commitment is not then in effect, the outstanding principal balance of the Loans) of the assigning Lender subject to each such assignment (determined as of the date the Assignment and Assumption with respect to such assignment is delivered to the Administrative Agent) shall be $5,000,000 or any increment of $1,000,000 in excess thereof; provided that related Approved Funds shall be aggregated for purposes of such minimum assigned amount;

(B) each partial assignment shall be made as an assignment of a proportionate part of all the assigning Lender’s rights and obligations under this Agreement;

(C) the parties to each assignment shall execute and deliver to the Administrative Agent an Assignment and Assumption, together with a processing and recordation fee of $3,500; provided that only one such fee shall be payable in connection with simultaneous assignments to or by two or more related Approved Funds;

(D) the assignee, if it shall not be a Lender, shall deliver to the Administrative Agent an Administrative Questionnaire in which the assignee designates one or more individuals (each such individual, a “Credit Contact”) to whom all syndicate-level information (which may contain material non-public information about the Borrowers, the Credit Parties and their Related Parties or their respective securities) will be made available and who may receive such information in accordance with the assignee’s compliance procedures and applicable laws, including Federal and state securities laws;

(E) in the case of an assignment by a Lender to a CLO (as defined below) managed or administered by such Lender or an Affiliate of such Lender, the assigning Lender shall retain the sole right to approve any amendment, modification or waiver of any provision of this Agreement, provided that the Assignment and Assumption between such Lender and such CLO may provide that such Lender will not, without the consent of such CLO, agree to any amendment, modification or waiver described in the first proviso to Section 10.02(b) that affects such CLO; and

-79-

(F) no assignment shall be made to (x) any Borrower or any Subsidiary or Affiliate of any Borrower or (y) any Defaulting Lender or any of its subsidiaries, or to any Person who, upon becoming a Lender hereunder, would constitute any of the foregoing Persons.

For the purposes of this Section 10.04(b), the terms “Approved Fund” and “CLO” have the following meanings:

“Approved Fund” means, with respect to any Lender, (a) a CLO managed or administered by such Lender or an Affiliate of such Lender and (b) with respect to any Lender that is a fund which invests in bank loans and similar extensions of credit, any other fund that invests in bank loans and similar extensions of credit and is managed by the same investment advisor as such Lender or by an Affiliate of such investment advisor.

“CLO” means, with respect to any Lender, any entity (whether a corporation, partnership, trust or otherwise) that is engaged in making, purchasing, holding or otherwise investing in bank loans and similar extensions of credit in the ordinary course and is administered or managed by such Lender or an Affiliate of such Lender.

(iii) Subject to execution and delivery thereof and acceptance and recording thereof pursuant to paragraph (b)(iv) of this Section, from and after the effective date specified in each Assignment and Assumption the assignee thereunder shall be a party hereto and, to the extent of the interest assigned by such Assignment and Assumption, have the rights and obligations of a Lender under this Agreement, and the assigning Lender thereunder shall, to the extent of the interest assigned by such Assignment and Assumption, be released from its obligations under this Agreement (and, in the case of an Assignment and Assumption covering all of the assigning Lender’s rights and obligations under this Agreement, such Lender shall cease to be a party hereto but shall continue to be entitled to the benefits of Section 2.13, Section 2.14, Section 2.15, and Section 10.03); provided that except to the extent otherwise expressly agreed by the affected parties, no assignment by a Defaulting Lender will constitute a waiver or release of any claim of any party hereunder arising from that Lender’s having been a Defaulting Lender. Any assignment or transfer by a Lender of rights or obligations under this Agreement that does not comply with this Section 10.04 shall be treated for purposes of this Agreement as a sale by such Lender of a participation in such rights and obligations in accordance with paragraph (c) of this Section.

(iv) The Administrative Agent, acting for this purpose as an agent of the Borrowers, shall maintain at one of its offices a copy of each Assignment and Assumption delivered to it and a register for the recordation of the names and addresses of the Lenders, and the Commitment of, and principal amount of the Loans and LC Disbursements owing to, each Lender pursuant to the terms hereof from time to time (the “Register”). The entries in the Register as to the identity of the Lenders shall be conclusive, and as to the other items referred to above shall be conclusive absent manifest error, and the Borrowers, the Administrative Agent, each Issuing Bank and the Lenders may 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. In addition, the Administrative Agent shall maintain on the Register information regarding the designation, and revocation of designation, of any Lender as a Defaulting Lender. The Register shall be available for inspection by the Company, any Issuing Bank and any Lender, at any reasonable time and from time to time upon reasonable prior notice.

-80-

(v) Upon its receipt of a duly completed Assignment and Assumption executed by an assigning Lender and an assignee, the assignee’s completed Administrative Questionnaire (unless the assignee shall already be a Lender hereunder), the processing and recordation fee referred to in paragraph (b) of this Section and any written consent to such assignment required by paragraph (b) of this Section, the Administrative Agent shall accept such Assignment and Assumption 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) Any Lender may, without the consent of the Borrowers, the Administrative Agent, or any Issuing Bank, sell participations to one or more banks or other entities (other than a Defaulting Lender or a subsidiary thereof) (a “Participant”) in all or a portion of such Lender’s rights and obligations under this Agreement (including all or a portion of its Commitment and the Loans owing to it and Notes held by it); provided that (i) such Lender’s obligations under this Agreement shall remain unchanged, (ii) such Lender shall remain the holder of its Notes (if any) for all purposes of this Agreement and shall remain solely responsible to the other parties hereto for the performance of such obligations and (iii) the Borrowers, the Administrative Agent, each Issuing Bank 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 pursuant to which a Lender sells such a participation shall provide that such Lender shall retain the sole right to enforce this Agreement and to approve any amendment, modification or waiver of any provision of this Agreement; provided that 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 the first proviso to Section 10.02(b) that affects such Participant. Subject to paragraph (d) of this Section, the Borrowers agree that each Participant shall be entitled to the benefits of Section 2.13, Section 2.14 and Section 2.15 with respect to its participations hereunder to the same extent as if it were a Lender and had acquired its interest by assignment pursuant to paragraph (b) of this Section, provided that such Participant shall have complied with any obligation in respect thereof that it would have had as a Lender. To the extent permitted by law, each Participant also shall be entitled to the benefits of Section 10.08 as though it were a Lender, provided such Participant agrees to be subject to Section 2.16(c) as though it were a Lender. Each Lender that sells a participation shall, acting solely for this purpose as a non-fiduciary agent of the Borrowers, 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 commitments, loans, letters of credit or its other obligations under any Loan Document) except to the extent that the relevant parties, acting reasonably and in good faith, determine that such disclosure is necessary to establish that such commitment, loan, letter of credit or other obligation is in registered form under Section 5f.103-1(c) of the United States Treasury Regulations. Unless otherwise required by the Internal Revenue Service (the “IRS”), any disclosure required by the foregoing sentence shall be made by the relevant Lender directly and solely to the IRS. The entries in the Participant Register shall be conclusive absent clearly demonstrable 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.

-81-

(d) A Participant shall not be entitled to receive any greater payment under Section 2.13, or Section 2.15 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 Company’s prior written consent. A Participant that would be a Foreign Lender if it were a Lender shall not be entitled to the benefits of Section 2.15 unless the Company is notified of the participation sold to such Participant and such Participant agrees, for the benefit of the Borrowers, to comply with Section 2.15(e) and (f) as though it were a Lender.

(e) Any Lender may at any time pledge or assign a security interest in all or any portion of its rights under this Agreement to secure obligations of such Lender, including any pledge or assignment to secure obligations to a Federal Reserve Bank or a central bank with 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.

(f) In connection with any assignment of rights and obligations of any Defaulting Lender hereunder, no such assignment shall be effective unless and until, in addition to the other conditions thereto set forth herein, the parties to the assignment shall make such additional payments to the Administrative Agent in an aggregate amount sufficient, upon distribution thereof as appropriate (which may be outright payment, purchases by the assignee of participations or subparticipations, or other compensating actions, including funding, with the consent of the Borrowers and the Administrative Agent, the applicable pro rata share of Loans previously requested but not funded by the Defaulting Lender, to each of which the applicable assignee and assignor hereby irrevocably consent), to (x) pay and satisfy in full all payment liabilities then owed by such Defaulting Lender to the Administrative Agent, each Issuing Bank, and each Lender hereunder (and interest accrued thereon) and (y) acquire (and fund as appropriate) its full pro rata share of all Loans and participations in Letters of Credit in accordance with its Percentage. Notwithstanding the foregoing, in the event that any assignment of rights and obligations of any Defaulting Lender hereunder shall become effective under applicable law without compliance with the provisions of this paragraph, then the assignee of such interest shall be deemed to be a Defaulting Lender for all purposes of this Agreement until such compliance occurs.

Section 10.05. Survival. All covenants, agreements, representations and warranties made by the Borrowers herein and in the certificates or other instruments delivered in connection with or pursuant to this Agreement shall be considered to have been relied upon by the other parties hereto and shall survive the execution and delivery of this Agreement and the making of any Loans and issuance of any Letters of Credit, regardless of any investigation made by any such other party or on its behalf and notwithstanding that the Administrative Agent, any Issuing Bank or any Lender may have had notice or knowledge of any Default or incorrect representation or warranty at the time any credit is extended hereunder, and shall continue in full force and effect as of the date made, or any date referred to therein, as applicable, (but without being deemed remade on or as of any subsequent date by reason of this Section 10.05) as long as the principal of or any accrued interest on any Loan or any fee or any other amount payable under this Agreement is outstanding and unpaid or any Letter of Credit is outstanding and so long as the Commitments have not expired or terminated. The provisions of Section 2.13, Section 2.14, Section 2.15, and Section 10.03 and ARTICLE 9 shall survive and remain in full force and effect regardless of the consummation of the transactions contemplated hereby, the repayment of the Loans, the expiration or termination of the Letters of Credit and the Commitments or the termination of this Agreement or any provision hereof.

-82-

Section 10.06. Counterparts; Integration; Effectiveness. This Agreement may be executed in counterparts (and by different parties hereto on different counterparts), each of which shall constitute an original, but all of which when taken together shall constitute a single contract. This Agreement and the other Loan Documents and any separate letter agreements with respect to fees payable to the Administrative Agent constitute the entire contract among the parties relating to the subject matter hereof and supersede any and all previous agreements and understandings, oral or written, relating to the subject matter hereof. Except as provided in Section 3.01, this Agreement shall become effective when it shall have been executed by the Administrative Agent and when the Administrative Agent shall have received counterparts hereof which, when taken together, bear the signatures of each of the other parties hereto, and thereafter shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns. Delivery of an executed counterpart of a signature page of this Agreement by telecopy or other electronic transmission (such as .pdf format) shall be effective as delivery of a manually executed counterpart of this Agreement.

Section 10.07. Severability. To the fullest extent permitted by applicable law any provision of this Agreement held to be invalid, illegal or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such invalidity, illegality or unenforceability without affecting the validity, legality and enforceability of the remaining provisions hereof; and the invalidity of a particular provision in a particular jurisdiction shall not invalidate such provision in any other jurisdiction. Without limiting the foregoing provisions of this Section 10.07, if and to the extent that the enforceability of any provisions in this Agreement relating to Defaulting Lender shall be limited by applicable law, as determined in good faith by the Administrative Agent or any Issuing Bank, as applicable, then such provisions shall be deemed to be in effect only to the extent not so limited.

Section 10.08. Right of Setoff. If an Event of Default shall have occurred and be continuing, subject to the terms and provisions of the Security Agreement and the other Loan Documents, each Lender and each of its Affiliates 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 obligations at any time owing by such Lender or Affiliate to or for the credit or the account of a Borrower against any of and all the obligations of such Borrower now or hereafter existing under this Agreement held by such Lender, irrespective of whether or not such Lender shall have made any demand under this Agreement and although such obligations may be unmatured. The rights of each Lender under this Section are in addition to other rights and remedies (including other rights of setoff) which such Lender may have but are subject to the terms and provisions of the Security Agreement and the other Loan Documents. In the event that any Defaulting Lender shall exercise any such right of setoff, (a) all amounts so set off shall be paid over immediately to the Administrative Agent for further application in accordance with the provisions of Section 2.18 and, pending such payment, shall be segregated by such Defaulting Lender from its other funds and deemed held in trust for the benefit of the Administrative Agent, the Issuing Banks and the Lenders, and (b) the Defaulting Lender shall provide promptly to the Administrative Agent a statement describing in reasonable detail the Obligations owing to such Defaulting Lender as to which it exercised such right of setoff.

-83-

(b) Each Borrower hereby irrevocably and unconditionally submits, for itself and its property, to the nonexclusive jurisdiction of the Supreme Court of the State of New York sitting in New York County and of the United States District Court of the Southern District of New York, and any appellate court from any thereof, in any action or proceeding by the Administrative Agent, the Collateral Agent, any Issuing Bank or any Lender arising out of or relating to this Agreement, or for recognition or enforcement of any judgment obtained in any such action or proceeding, 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. 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 shall affect any right that the Administrative Agent, any Issuing Bank or any Lender may otherwise have to bring any action or proceeding relating to this Agreement against any Borrower or its properties in the courts of any jurisdiction.

(c) Each Borrower 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 in any court referred to in paragraph (b) of this Section. 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.

(d) Each party to this Agreement irrevocably consents to service of process in any action or proceeding referred to in Section 9.09 by the mailing thereof by certified mail, return receipt requested, addressed as provided in Section 9.01(a), with a copy thereof to the “General Counsel” of such Person at such same address.

EACH PARTY HERETO HEREBY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN ANY LEGAL PROCEEDING DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY (WHETHER BASED ON CONTRACT, TORT OR ANY OTHER THEORY). EACH PARTY HERETO (a) 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 (b) ACKNOWLEDGES THAT IT AND THE OTHER PARTIES HERETO HAVE BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION.

Section 10.12. Confidentiality. Each of the Administrative Agent, the Collateral Agent, each Issuing Bank and the Lenders agrees to maintain the confidentiality of the Information (as defined below), except that Information may be disclosed (a) to its and its Affiliates’ directors, officers, employees and agents, including accountants, legal counsel and other advisors involved in the financing provided for herein (it being understood that the Persons to whom such disclosure is made will be informed of the confidential nature of such Information and instructed to keep such Information confidential), (b) to the extent requested by any regulatory authority, (c) to the extent required by applicable laws or regulations or by any subpoena or similar legal process, applicable to it, (d) to any other party to this Agreement, (e) in connection with the exercise of any remedies hereunder or any suit, action or proceeding relating to this Agreement or the enforcement of rights hereunder, (f) subject to an agreement to comply with the provisions of this Section 9.12 or a separate agreement containing provisions at least as restrictive as those of this Section, to (i) any assignee of or Participant in, or any prospective assignee of or Participant in, any of its rights or obligations under this Agreement, (ii) any pledgee referred to in Section 9.04(e) or (iii) any actual or prospective counterparty (or its advisors) to any swap or derivative transaction relating to any Borrower and its obligations, (g) with the consent of a Borrower or (h) to the extent such Information (i) becomes publicly available other than as a result of a breach of this Section or (ii) becomes available to the Administrative Agent, the Collateral Agent, any Issuing Bank or any Lender on a nonconfidential basis from a source other than a Borrower or any of its Subsidiaries, the Administrative Agent, the Collateral Agent, any Issuing Bank or any other Lender. For the purposes of this Section, “Information” means all information received from a Borrower or any of its Subsidiaries relating to any Borrower or any of its Subsidiaries or its businesses, other than any such information that is available to the Administrative Agent, the Collateral Agent, any Issuing Bank or any Lender on a nonconfidential basis prior to disclosure by such Borrower; provided that, in the case of information received from a Borrower after the date hereof, such information is clearly identified at the time of delivery as confidential. Any Person required to maintain the confidentiality of Information as provided in this Section shall be considered to have complied with its obligation to do so if such Person has exercised the same degree of care to maintain the confidentiality of such Information as such Person would accord to its own confidential information; and nothing in the foregoing authorization shall apply to any disclosure that would constitute a violation of applicable federal and state securities laws.

Section 10.16. Release Upon Pipeline Company Borrower Drop-down.

SCHEDULE 3

PRICING SCHEDULE

“Applicable Margin” means, for any day, for purposes of calculating commitment fees on Commitments or interest on Loans, the rate per annum set forth below in the applicable row opposite such term and in the column corresponding to the Pricing Level that applies on such day:

	Level I	Level II	Level III	Level IV	Level V
Commitment Fees	0.25%	0.30%	0.40%	0.45%	0.50%
ABR Loan Margin	0.50%	0.75%	1.00%	1.25%	1.50%
Euro-Dollar Loan Margin	1.50%	1.75%	2.00%	2.25%	2.50%

For purposes of this Schedule, the following terms have the following meanings, subject to the concluding paragraphs of this Schedule:

“Fitch” means Fitch Ratings, Ltd.

“Level I Pricing” applies on any day on which the Reference Rating is BBB/Baa2/BBB or higher.

“Level II Pricing” applies on any day on which the Reference Rating is BBB-/Baa3/BBB-.

“Level III Pricing” applies on any day on which the Reference Rating is BB+/Ba1/BB+.

“Level IV Pricing” applies on any day on which the Reference Rating is BB/Ba2/BB.

“Level V Pricing” applies on any day if no other Pricing Level applies on such day.

“Moody's” means Moody's Investors Service, Inc.

“Pricing Level” refers to the determination of which of Level I, Level II, Level III, Level IV or Level V Pricing applies on any day.

“Rating Agency” means Fitch, Moody’s or S&P.

Schedule 3 - Page 1 of 2

Fourth Amended and Restated Credit Agreement

The “Reference Rating” is the credit rating assigned to the Loans by the relevant rating agency; provided that (i) until such time as Moody's and S&P assigns an initial rating to the Loans, the Moody's and S&P ratings of the Existing Facility shall be deemed to be its Reference Rating and (ii) until the Borrowers engage Fitch to rate the Loans, Fitch's ratings shall be deemed to be unavailable. The rating in effect for any day is that in effect at the close of business on such day.

“S&P” means Standard & Poor's Financial Services LLC, a subsidiary of The McGraw-Hill Companies, Inc.

The following rules shall apply in determining which Pricing Level applies:

In the event that Reference Ratings are not available from all three Rating Agencies, (i) if the Reference Rating from Fitch is unavailable, Moody's and S&P's Reference Ratings shall apply and, if both Reference Ratings from Moody's and S&P are available but not the same, then (A) if the difference is one notch, the higher such rating will govern so long as it is at least BBB- or Baa3 or higher, but the lower rating will govern if that requirement is not met, and (B) if the difference is more than one notch, a Reference Rating one notch below the higher of the two will govern; (ii) if the Reference Rating from either Moody’s or S&P is unavailable, then the Fitch Reference Rating shall not apply and the Pricing Level will be determined on the basis of the available Reference Rating from Moody’s or S&P; and (iii) if the Reference Ratings from both Moody's and S&P are unavailable, then Level V shall apply.

In the event Reference Ratings from all three Rating Agencies are available, then (i) the majority Reference Rating will govern, if two such ratings are the same or (ii) the middle Reference Rating will govern, if all three such ratings differ.

If the rating system of any Rating Agency shall change, the Borrowers and the Lenders shall negotiate in good faith to amend this Schedule to reflect such changed rating system and, pending the effectiveness of any such amendment, the Applicable Rate shall be determined without reference to such Rating Agency.

The undersigned further agrees to pay interest in like money at such office on the unpaid principal amount hereof from time to time from the date hereof at the applicable rate per annum set forth in Section 2.11 of the Credit Agreement until any such amount shall become due and payable (whether at the stated maturity, by acceleration or otherwise), and thereafter on such overdue amount at the rate per annum set forth in paragraph (c) of Section 2.11 of the Credit Agreement until paid in full (both before and after judgment). Interest shall be payable in arrears on each Interest Payment Date commencing on the first such date to occur after the date hereof, provided that interest accruing pursuant to paragraph (c) of Section 2.11 of the Credit Agreement shall be payable on demand. In no event shall the interest payable hereon, whether before or after maturity, exceed the maximum interest which, under applicable law, may be charged on this Note, and this Note is expressly made subject to the provisions of the Credit Agreement which more fully sets out the limitations on how interest accrues hereon.

The holder of this Note is authorized to record the date, type and amount of each Loan made by the Lender pursuant to Section 2.02 of the Credit Agreement, each continuation thereof, each conversion of all or a portion thereof to another type, the date and amount of each payment or prepayment of principal with respect thereto, and, in the case of Eurodollar Loans, the length of each Interest Period with respect thereto, on the schedules annexed hereto and made a part hereof, or on a continuation thereof which shall be attached hereto and made a part hereof, which recordation shall constitute prima facie evidence of the accuracy of the information recorded in the absence of manifest error; provided that failure by the Lender to make any such recordation on this Note shall not affect the obligations of the Borrower under this Note or the Credit Agreement.

This Note is one of the Notes referred to in the Fourth Amended and Restated Credit Agreement, dated as of May 27, 2011 (as amended, supplemented or otherwise modified from time to time, the “Credit Agreement”), among the Borrower, [the Company], [EPNGC] and [TGPC], the Lender, the other financial institutions parties thereto, and JPMorgan Chase Bank, N.A., as administrative agent and as collateral agent, is entitled to the benefits thereof, is secured as provided therein and in the Security Documents and is subject to optional and mandatory prepayment in whole or in part as provided therein.

Upon the occurrence of any one or more of the Events of Default specified in the Credit Agreement, all amounts then remaining unpaid on this Note shall become, or may be declared to be, immediately due and payable all as provided therein.

[This Note is given in replacement and substitution for, but not payment or satisfaction of, one or more revolving credit notes previously issued under the Existing Facility by the Borrower in favor of Lender. The indebtedness evidenced by such other revolving credit note or notes is continued in full force and effect (but not duplicated) hereunder. This Note evidences existing indebtedness under the Existing Facility and does not constitute payment of such indebtedness, and such indebtedness continues (but is not duplicated) in full force and effect, as amended and restated in the Credit Agreement.]

With respect to any Equity Interests pledged by such Credit Party to the Collateral Agent hereunder that are uncertificated securities, such Credit Party has caused the issuer thereof to agree in an authenticated record with such Credit Party and the Collateral Agent that such issuer will comply with instructions with respect to such uncertificated securities originated by the Collateral Agent without further consent of such Credit Party and has delivered a copy of such authenticated record to the Collateral Agent. If such Credit Party is a Pledged Company, such Credit Party confirms that it has received notice of such security interest.

(i) With respect to any Credit Party that is a Grantor, the Initial Pledged Equity as set forth on Schedule II (as such schedule may be amended or supplemented from time to time) pledged as Collateral by such Credit Party to the Collateral Agent hereunder constitutes as of the date of this Agreement 100% of the issued and outstanding Equity Interests of each issuer thereof.

All representations and warranties made by the Credit Parties herein, and in any other Security Document delivered pursuant hereto, shall survive the execution and delivery by the Credit Parties of the Security Documents. The Credit Parties shall deliver to the Collateral Agent amended and restated schedules (the “Amended Schedules”) to this Agreement in the event that any information contained on the schedules attached hereto becomes inaccurate. Such Amended Schedules shall replace the schedules provided by the Credit Parties on the Effective Date, and shall be deemed the schedules to this Agreement. Each Credit Party will not change its name, identity, corporate structure (including, without limitation, its jurisdiction of formation) or the location of its registered office without (i) giving the Collateral Agent at least 5 Business Days’ prior written notice clearly describing such new name, identity, corporate structure or new location and providing such other information in connection therewith as the Collateral Agent may reasonably request, and (ii) taking all action satisfactory to the Collateral Agent at the expense of such Credit Party as the Collateral Agent may request to maintain the security interest of the Collateral Agent in the Collateral intended to be granted hereby at all times fully perfected with the same priority and in full force and effect.

Section 4.04. Payments in Trust.

If no Event of Default then exists, interest and proceeds resulting from an investment of funds in any Pledged Account in Cash Equivalents shall be, promptly upon request of the Company, transferred to the Company to be used for general corporate purposes.

Fourth Amended and Restated Credit Agreement

EXHIBIT F

ACCEPTABLE SUBORDINATION PROVISIONS

[NAME OF BORROWER], a [Delaware] corporation (together with its successors, the “Borrower”), and [NAME OF LENDER], a [Delaware] corporation (together with its successors, “Lender”), agree for the benefit of the Senior Debt (as defined below) that all indebtedness evidenced by this [PROMISSORY NOTE] (this “Note”), including principal, premium, if any, and interest, and all other amounts payable to Lender hereunder (including, for all purposes of this Note, any payment in respect of redemption or purchase or other acquisition hereof) (collectively, the “Subordinated Debt”) shall, to the extent hereinafter set forth, be subordinate and junior to all Senior Debt.

Unless and until all principal of, premium, if any, and interest on, and all other obligations of the Borrower under, any Senior Debt shall have been paid in full and all commitments to extend Senior Debt shall have terminated, neither the Borrower nor any of its Subsidiaries or Affiliates shall make, and Lender shall not demand, accept or receive, or attempt to collect or commence any legal proceedings to collect, any direct or indirect payment (in cash or property or by setoff, exercise of contractual or statutory rights or otherwise) of or on account of any amount payable on or with respect to this Note (including any payment in respect of redemption or purchase or other acquisition) or any interest herein. Unless and until all principal of, premium, if any, and interest on, and all other obligations of the Borrower under, the Senior Debt shall have been paid in full and all commitments to extend Senior Debt shall have terminated, Lender will not commence or maintain any action, suit or any other legal or equitable proceeding against the Borrower, or join with any creditor in any such proceeding, under any insolvency, bankruptcy, receivership, liquidation, reorganization or other similar law, unless the holders of Senior Debt shall also join in bringing such proceeding; provided that the foregoing shall not prohibit Lender from filing a proof of claim or otherwise participating in any such proceeding not commenced by it.

In the event of any insolvency or bankruptcy proceedings, and any receivership, liquidation, reorganization or other similar proceedings in connection therewith, relative to the Borrower or to its creditors, in their capacity as creditors of the Borrower, or to substantially all of its property, and in the event of any proceedings for voluntary liquidation, dissolution or other winding up of the Borrower, whether or not involving insolvency or bankruptcy, then:

(a) the holders of the Senior Debt shall first be entitled to receive payment in full of the principal thereof, premium, if any, interest and all other amounts payable thereon (accruing before and after the commencement of the proceedings, whether or not allowed or allowable as a claim in such proceedings) before Lender is entitled to receive any payment on account or in respect of Subordinated Debt; and

Exhibit F – Page 1

Fourth Amended and Restated Credit Agreement

(b) any payment or distribution of assets of the Borrower of any kind or character, whether in cash, property or securities to which Lender would be entitled, but for the provisions of this Note, shall be paid or distributed by the liquidating trustee or agent or other person making such payment or distribution, whether a trustee in bankruptcy, a receiver or liquidating trustee or other trustee or agent, directly to the Agent (as defined below) and any other representative on behalf of the holders of Senior Debt to the extent necessary to make payment in full of all amounts of Senior Debt remaining unpaid, after giving effect to any concurrent payment or distribution to the holders of the Senior Debt.

Should any payment or distribution or security or the proceeds of any thereof be collected or received by Lender in respect of the Subordinated Debt, at a time when the payment thereof by the Borrower is prohibited by the terms of this Note, Lender will forthwith deliver the same to the Agent and any other representative on behalf of the holders of Senior Debt for the equal and ratable benefit of the holders of the Senior Debt in precisely the form received (except for the endorsement or the assignment of or by Lender where necessary) for application to payment of all Senior Debt in full, after giving effect to any concurrent payment or distribution to the holders of Senior Debt and, until so delivered, the same shall be held in trust by Lender as the property of the holders of the Senior Debt.

Lender shall not be subrogated to the rights of the holders of the Senior Debt to receive payments or distributions of assets of the Borrower until all amounts payable with respect to the Senior Debt shall be paid in full; and, for the purposes of such subrogation, no payments or distributions to the holders of the Senior Debt of any cash, property or securities to which Lender would be entitled except for these provisions shall, as between the Borrower, its creditors other than the holders of the Senior Debt, and Lender, be deemed to be a payment by the Borrower to or on account of the Senior Debt. The subordination provisions of this Note are and are intended solely for the purpose of defining the relative rights of Lender, on the one hand, and the holders of the Senior Debt, on the other hand.

Subject to the payment in full of all of the Senior Debt, Lender shall be subrogated to the rights of the holders of Senior Debt to receive payments or distributions of cash, property or securities of the Borrower applicable to the Senior Debt until all amounts owing on the Subordinated Debt shall be paid in full. For purposes of such subrogation, no payments or distributions to Lender of cash, property, securities or other assets by virtue of the subrogation herein provided which otherwise would have been made to the holders of the Senior Debt shall, as between the Borrower, its creditors other than the holders of Senior Debt and Lender, be deemed to be a payment to or on account of the Subordinated Debt. Lender agrees that, in the event that all or any part of any payment made on account of the Senior Debt is recovered from the holders of Senior Debt as a preference, fraudulent transfer or similar payment under any bankruptcy, insolvency or similar law, any payment or distribution received by Lender on account of the Subordinated Debt at any time after the date of the payment so recovered, whether pursuant to the right of subrogation provided for in this Subordinated Note or otherwise, shall be deemed to have been received by Lender in trust as the property of the holders of the Senior Debt and Lender shall forthwith deliver the same to the Agent and any other representative on behalf of the holders of the Senior Debt for the equal and ratable benefit of the holders of the Senior Debt for application to payment of all Senior Debt in full.

Exhibit F – Page 2

Fourth Amended and Restated Credit Agreement

Lender hereby waives any and all notice in respect of the Senior Debt, present or future, and agrees and consents that without notice to or assent by any holder or holders of the Subordinated Debt:

(i) the obligation and liabilities of the Borrower or any other party or parties for or upon the Senior Debt (or any promissory note, security document or guaranty evidencing or securing the same) may, from time to time, in whole or in part, be renewed, extended, modified, amended, restated, accelerated, compromised, supplemented, terminated, sold, exchanged, waived or released;

(ii) the Agent and the holders of the Senior Debt may exercise or refrain from exercising any right, remedy or power granted by or in connection with any agreements relating to the Senior Debt; and

(iii) any balance or balances of funds with any holders of the Senior Debt at any time standing to the credit of the Borrower may, from time to time, in whole or in part, be surrendered or released;

all as the Agent or the holders of the Senior Debt may deem advisable and all without impairing, abridging, diminishing, releasing or affecting the subordination of the Subordinated Debt to the Senior Debt provided for herein.

Nothing contained in the subordination provisions of this Note is intended to or shall impair, as between the Borrower, its creditors other than the holders of the Senior Debt, and Lender, the obligation of the Borrower, which is absolute and unconditional, to pay to Lender the principal of, premium, if any, and interest on this Note, as and when the same shall become due and payable (except as otherwise provided in this Note) in accordance with its terms, or is intended to or shall affect the relative rights of Lender and other creditors of the Borrower other than the holders of the Senior Debt.

Lender acknowledges and agrees that the holders of the Senior Debt have relied upon and will continue to rely upon the subordination provided for herein in entering into the agreements relating to Senior Debt and in extending credit to the Borrower pursuant thereto.

No present or future holder of Senior Debt shall be prejudiced in his right to enforce the subordination contained herein in accordance with the terms hereof by any act or failure to act on the part of the Borrower or Lender. The subordination provisions contained herein are for the benefit of the holders of the Senior Debt from time to time and, so long as any Senior Debt is outstanding under any agreement, may not be rescinded, cancelled or modified in any way without the prior written consent thereto of all holders of Senior Debt.

Exhibit F – Page 3

Fourth Amended and Restated Credit Agreement

Notwithstanding anything to the contrary in this Note, upon any payment or distribution of assets of the Borrower in any proceedings for reorganization, insolvency, liquidation, dissolution or other winding up, Lender shall be entitled to rely upon any final order or decree made by any court of competent jurisdiction in which any such proceedings are pending for the purpose of ascertaining the persons entitled to participate in such payment or distribution, the holders of the Senior Debt and other debt of the Borrower, the amount thereof or payable thereon, the amount or amounts paid or distributed thereon and all other facts pertinent thereto.

The subordination provisions hereof shall be binding upon any holder of Subordinated Debt and upon the successors and assigns of Lender; and all references herein to Lender shall be deemed to include any successor or successors, whether immediate or remote, to Lender.

The following terms, as used herein, have the following respective meanings:
