(iv) if the Majority Lenders shall, at least one Business Day before the date of any requested Borrowing, notify the Administrative Agent and the Borrower that the Eurodollar Rate for Eurodollar Rate Advances comprising such Borrowing will not adequately reflect the cost to such Lenders of making or funding their respective Eurodollar Rate Advances, as the case may be, for such Borrowing, the right of the Borrower to select Eurodollar Rate Advances for such Borrowing or for any subsequent Borrowing shall be suspended until the Administrative Agent shall notify the Borrower and the Lenders that the circumstances causing such suspension no longer exist, and each Advance comprising such Borrowing shall be an Alternate Base Rate Advance;

(e) Administrative Agent Reliance . Unless the Administrative Agent shall have received notice from a Lender before the date of any Borrowing that such Lender shall not make available to the Administrative Agent such Lender’s Pro Rata Share of the Borrowing, the Administrative Agent may assume that such Lender has made its Pro Rata Share of such Borrowing available to the Administrative Agent on the date of such Borrowing in accordance with Section 2.02(a) and the Administrative Agent may, in reliance upon such assumption, make available to the Borrower on such date a corresponding amount. If and to the extent that such Lender shall not have so made its Pro Rata Share of such Borrowing available to the Administrative Agent, such Lender and the Borrower severally agree to immediately repay to the Administrative Agent on demand such corresponding amount, together with interest on such amount, for each day from the date such amount is made available to the Borrower until the date such amount is repaid to the Administrative Agent, at (i) in the case of the Borrower, the interest rate applicable on such day to Advances comprising such Borrowing and (ii) in the case of such Lender, the Federal Funds Rate for such day. If such Lender shall repay to the Administrative Agent such corresponding amount and interest as provided above, such corresponding amount so repaid shall constitute such Lender’s Advance as part of such Borrowing for purposes of this Agreement even though not made on the same day as the other Advances comprising such Borrowing.

(f) Lenders’ Obligations Several . The failure of any Lender to make the Advance to be made by it as part of any Borrowing shall not relieve any other Lender of its obligation, if any, to make its Advance on the date of such Borrowing.

(i) If, with respect to any Lender, the effective rate of interest contracted for under the Credit Documents, including the stated rates of interest and fees contracted for hereunder and any other amounts contracted for under the Credit Documents which are deemed to be interest, at any time exceeds the Maximum Rate, then the outstanding principal amount of the loans made by such Lender hereunder shall bear interest at a rate which would make the effective rate of interest for such Lender under the Credit Documents equal the Maximum Rate until the difference between the amounts which would have been due at the stated rates and the amounts which were due at the Maximum Rate (the “ Lost Interest ”) has been recaptured by such Lender.

(ii) If, when the loans made hereunder are repaid in full, the Lost Interest has not been fully recaptured by such Lender pursuant to the preceding paragraph, then, to the extent permitted by law, for the loans made hereunder by such Lender the interest rates charged under Section 2.07 hereunder shall be retroactively increased such that the effective rate of interest under the Credit Documents was at the Maximum Rate since the effectiveness of this Agreement to the extent necessary to recapture the Lost Interest not recaptured pursuant to the preceding sentence and, to the extent allowed by law, the Borrower shall pay to such Lender the amount of the Lost Interest remaining to be recaptured by such Lender.

(iii) Notwithstanding the foregoing or any other term in this Agreement and the Credit Documents to the contrary, it is the intention of each Lender and the Borrower to conform strictly to any applicable usury laws. Accordingly, if any Lender contracts for, charges, or receives any consideration which constitutes interest in excess of the Maximum Rate, then any such excess shall be canceled automatically and, if previously paid, shall at such Lender’s option be applied to the outstanding amount of the loans made hereunder by such Lender or be refunded to the Borrower.

All computations of interest based on the Alternate Base Rate shall be made by the Administrative Agent on the basis of a year of 365 or 366 days, as the case may be, and all computations of interest based on the Eurodollar Rate and the Federal Funds Rate and of fees shall be made by the Administrative Agent, on the basis of a year of 360 days, in each case for the actual number of days (including the first day, but excluding the last day) occurring in the period for which such interest or fees are payable. Each determination by the Administrative Agent of an interest rate or fee shall be conclusive and binding for all purposes, absent manifest error.

(c) Non-Business Day Payments . Whenever any payment shall be stated to be due on a day other than a Business Day, such payment shall be made on the next succeeding Business Day, and such extension of time shall in such case be included in the computation of payment of interest or fees, as the case may be; provided , however , that if such extension would cause payment of interest on or principal of Eurodollar Rate Advances to be made in the next following calendar month, such payment shall be made on the next preceding Business Day.

(d) Administrative Agent Reliance . Unless the Administrative Agent shall have received written notice from the Borrower prior to the date on which any payment is due to the Lenders that the Borrower shall not make such payment in full, the Administrative Agent may assume that the Borrower has made such payment in full to the Administrative Agent on such date and the Administrative Agent may, in reliance upon such assumption, cause to be distributed to each Lender on such date an amount equal to the amount then due such Lender. If and to the extent the Borrower shall not have so made such payment in full to the Administrative Agent, each Lender shall repay to the Administrative Agent forthwith on demand such amount distributed to such Lender, together with interest, for each day from the date such amount is distributed to such Lender until the date such Lender repays such amount to the Administrative Agent, at the Federal Funds Rate for such day.

Section 2.09. Sharing of Payments, Etc . If any Lender shall obtain any payment (whether voluntary, involuntary, through the exercise of any right of set-off, or otherwise) on account of the Advances or Letter of Credit Obligations made by it in excess of its Pro Rata Share, as applicable, of payments on account of the Advances or Letter of Credit Obligations obtained by all the Lenders, such Lender shall notify the Administrative Agent and forthwith purchase from the other Lenders such participations in the Advances made by them or Letter of Credit Obligations held by them as shall be

necessary to cause such purchasing Lender to share the excess payment ratably with each of them; provided , however , that if all or any portion of such excess payment is thereafter recovered from such purchasing Lender, such purchase from each Lender shall be rescinded and such Lender shall repay to the purchasing Lender the purchase price to the extent of such Lender’s ratable share (according to the proportion of (a) the amount of the participation sold by such Lender to the purchasing Lender as a result of such excess payment to (b) the total amount of such excess payment) of such recovery, together with an amount equal to such Lender’s ratable share (according to the proportion of (i) the amount of such Lender’s required repayment to the purchasing Lender to (ii) the total amount of all such required repayments to the purchasing Lender) of any interest or other amount paid or payable by the purchasing Lender in respect of the total amount so recovered. The Borrower agrees that any Lender so purchasing a participation from another Lender pursuant to this Section 2.09 may, to the fullest extent permitted by law, exercise all its rights of payment (including the right of set-off) with respect to such participation as fully as if such Lender were the direct creditor of the Borrower in the amount of such participation.

Section 2.10. Breakage Costs.

similar credit facilities (to the extent such Lender has the right under such similar credit facilities to do so) with respect to any event referred to in the preceding clause (i) or (ii). A certificate as to the amount of such increased cost and detailing the calculation of such cost submitted to the Borrower and the Administrative Agent by such Lender shall be conclusive and binding for all purposes, absent manifest error.

A certificate as to the amounts showing in reasonable detail the calculation of the amounts submitted to the Borrower by such Lender or Issuing Bank shall be presumptively correct, absent manifest error.

(c) Letters of Credit . If any change in any law or regulation or in the interpretation thereof by any court or administrative or Governmental Authority charged with the administration thereof shall either (i) impose, modify, or deem applicable any reserve, special deposit, or similar requirement against letters of credit issued by, or assets held by, or deposits in or for the account of, an Issuing Bank or (ii) impose on an Issuing Bank any other condition regarding the provisions of this Agreement relating to the Letters of Credit or any Letter of Credit Obligations, and the result of any event referred to in the preceding clause (i) or (ii) shall be to increase the cost to such Issuing Bank of issuing or maintaining any Letter of Credit (which increase in cost shall be determined by such Issuing Bank’s reasonable allocation of the aggregate of such cost increases resulting from such event), then, upon demand by such Issuing Bank, the Borrower shall pay to the Administrative Agent for the account of such Issuing Bank, from time to time as specified by such Issuing Bank, additional amounts which shall be sufficient to compensate such Issuing Bank for such increased cost; provided that such Issuing Bank is generally seeking, or intends generally to seek, compensation from similarly situated borrowers under similar credit facilities (to the extent such Issuing Bank has the right under such similar credit facilities to do so) with respect to any event referred to in the preceding clause (i) or (ii). A certificate as to such increased cost incurred by such Issuing Bank, as a result of any event mentioned in clause (i) or

(ii) above, and detailing the calculation of such increased costs submitted by such Issuing Bank to the Borrower, shall be conclusive and binding for all purposes, absent manifest error.

(d) Limitation on Compensation . Failure or delay on the part of any Lender or any Issuing Bank to demand compensation pursuant to this Section shall not constitute a waiver of such Lender’s or such Issuing Bank’s right to demand such compensation; provided that the 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 Borrower of any change in any law or regulation or in the interpretation thereof by any court or administrative or Governmental Authority giving rise to such increased costs or reductions and of such Lender’s or such Issuing Bank’s intention to claim compensation therefor; provided , further , that, if the change in any law or regulation or in the interpretation thereof by any court or administrative or Governmental Authority 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.

In addition, the Borrower agrees to pay any present or future stamp or documentary taxes or any other excise or property taxes, charges or similar levies which arise from any payment made or from the execution, delivery or registration of, or otherwise with respect to, this Agreement, the Notes (if any), or the other Credit Documents (hereinafter referred to as “ Other Taxes ”).

(c) Lender Tax Status . Each Lender and Issuing Bank that is not organized under the laws of the United States of America or a state thereof (a “ Non-U.S. Lender ”) agrees that it shall deliver to the Borrower and the Administrative Agent on the date of this Agreement or upon, and as a condition to, the effectiveness of any Assignment and Acceptance (i) two duly completed copies of United States Internal Revenue Service Form W-8BEN or W-8BEN-E, as applicable, or W-8ECI or successor applicable form, as the case may be, certifying in each case that such Lender is entitled to receive payments under this Agreement and the Notes (if any) payable to it, without deduction or withholding of any United States federal income taxes, (ii) if applicable, an Internal Revenue Service Form W-8 or successor applicable form, as the case may be, to establish an exemption from United States backup withholding, and (iii) any other governmental forms which are necessary or required under an applicable tax treaty or otherwise by law to reduce or eliminate any withholding tax which have been reasonably requested by the Borrower. Each Lender that is organized under the laws of the United States of America or a state thereof shall deliver to the Borrower and the Administrative Agent on the date of this Agreement or upon, and as a condition to, the effectiveness of any Assignment and Acceptance an Internal Revenue Service Form W-9 or successor form to establish an exemption from United States backup withholding. Each Lender which delivers to the Borrower and the Administrative Agent a Form W-8BEN or W-8BEN-E, as applicable, or W-8ECI and Form W-8 or W-9 pursuant to the foregoing sentences further undertakes to deliver to the Borrower and the Administrative Agent two further copies of the said documents and Form W-8BEN or W-8BEN-E, as applicable, or W-8ECI and Form W-8 or W-9, or successor applicable forms, or other manner of certification, as the case may be, on or before the date that any such documents or form expires or becomes obsolete or after the occurrence of any event requiring a change in the most recent letter and form previously delivered by it to the Borrower and the Administrative Agent, and such extensions or renewals thereof as may reasonably be requested by the Borrower and the Administrative Agent certifying in the case of a Form W-8BEN or W-8BEN-E, as applicable, or W-8ECI that such Lender is entitled to receive payments under this Agreement without deduction or withholding of any United States federal income taxes. If an event (including without limitation any change in treaty, law or regulation) has occurred prior to the date on which any delivery required by the preceding sentence would otherwise be required which renders all such forms inapplicable or which would prevent any Lender from duly completing and delivering any such letter or form with respect to it and such Lender advises the Borrower and the Administrative Agent that it is not capable of receiving payments without any deduction or withholding of United States federal income tax, and in the case of a Form W-8 or W-9, establishing an exemption from United States backup withholding tax, such Lender shall not be required to deliver such letter or forms.

(d) FATCA . If a payment made to the Administrative Agent, a Lender, or an Issuing Bank under this Agreement would be subject to United States federal withholding tax imposed by

FATCA if the Administrative Agent, such Lender, or such Issuing Bank fails to comply with the applicable reporting requirements of FATCA (including those contained in Section 1471(b) or 1472(b) of the Code, as applicable), the Administrative Agent, such Lender, or such Issuing Bank shall deliver to the Withholding Agent, at the time or times prescribed by law and at such time or times reasonably requested by the Withholding Agent, such documentation prescribed by applicable law (including as prescribed by Section 1471(b)(3)(C)(i) of the Code) and such additional documentation reasonably requested by the Withholding Agent as may be necessary for the Withholding Agent to comply with its obligations under FATCA, to determine that the Administrative Agent, such Lender, or such Issuing Bank has complied with the Administrative Agent’s, such Lender’s, or such Issuing Bank’s obligations under FATCA or to determine the amount to deduct and withhold from such payment.

(e) Refunds . If the Administrative Agent, a Lender or an Issuing Bank determines, in its sole discretion, that it has received a refund of any Taxes or Other Taxes as to which it has been indemnified by the Borrower or with respect to which the Borrower has paid additional amounts pursuant to this Section, it shall pay to the Borrower an amount equal to such refund (but only to the extent of indemnity payments made, or additional amounts paid, by the Borrower under this Section with respect to the Taxes or Other Taxes giving rise to such refund), net of all out-of-pocket expenses of the Administrative Agent, such Lender or such Issuing Bank, as the case may be, and without interest (other than any interest paid by the relevant Governmental Authority with respect to such refund), provided that the Borrower, upon the request of the Administrative Agent, such Lender or such Issuing Bank, agrees to repay the amount paid over to the Borrower (plus any penalties, interest or other charges imposed by the relevant Governmental Authority) to the Administrative Agent, such Lender or such Issuing Bank in the event the Administrative Agent, such Lender or such Issuing Bank is required to repay such refund to such Governmental Authority. This paragraph shall not be construed to require the Administrative Agent, any Lender or an Issuing Bank to make available its tax returns (or any other information relating to its taxes that it deems confidential) to the Borrower or any other Person.

Section 2.13. Letters of Credit.

(a) Letter of Credit Commitment . From time to time from the date of this Agreement until the date which is five Business Days prior to the Revolver Termination Date, at the request of the Borrower or, if the Borrower makes such request to the Administrative Agent, the Administrative Agent, each Issuing Bank shall, on the terms and conditions hereinafter set forth, issue, increase, or extend the expiration date of Letters of Credit in an aggregate amount not to exceed its Letter of Credit Commitment for the account of the Borrower or any of its Subsidiaries on any Business Day. No Letter of Credit shall be issued, increased, or extended:

(i) unless such issuance, increase, or extension would not cause the Letter of Credit Exposure to exceed the lesser of (A) the Letter of Credit Sublimit or (B) the aggregate amount of the unused Commitments;

(ii) unless such Letter of Credit has an Expiration Date not later than the earlier of (A) twelve months after the date of issuance thereof (or, if extendable beyond such period, unless such Letter of Credit is cancelable upon at least thirty days’ notice given by the applicable Issuing Bank to the beneficiary of such Letter of Credit) and (B) five days prior to the Revolver Termination Date (unless the Borrower shall have deposited with the Administrative Agent into the Cash Collateral Account an amount equal to 102% of the face amount of such Letter of Credit);

(iii) unless such Letter of Credit Documents are in form and substance acceptable to the applicable Issuing Bank in its sole discretion;

(iv) unless such Letter of Credit is a standby letter of credit not supporting the repayment of indebtedness for borrowed money of any Person;

(v) unless the Borrower has delivered to the applicable Issuing Bank a completed and executed Letter of Credit Application; or

(vi) if any Lender is a Defaulting Lender, unless the applicable Issuing Bank has entered into arrangements, including the deposit by the Borrower with the Administrative Agent into the Cash Collateral Account such amount as such Issuing Bank may request, up to the maximum amount equal to the Letter of Credit Exposure of such Defaulting Lender, after giving effect to the provisions of Section 2.17(a)(iv).

(b) Participations . Upon the date of the issuance or increase of a Letter of Credit, the applicable Issuing Bank shall be deemed to have sold to each other Lender and each other Lender shall have been deemed to have purchased from such Issuing Bank a participation in the related Letter of Credit Obligations equal to such Lender’s Pro Rata Share at such date and such sale and purchase shall otherwise be in accordance with the terms of this Agreement. Such Issuing Bank shall promptly notify each such participant Lender by telex, telephone, or telecopy of each Letter of Credit issued, increased, or extended or converted and the actual dollar amount of such Lender’s participation in such Letter of Credit.

(c) Issuing . Each Letter of Credit shall be issued, increased, or extended pursuant to a Letter of Credit Application (or by telephone notice promptly confirmed in writing by a Letter of Credit Application or other means acceptable to the applicable Issuing Bank), given not later than 11:00 a.m. (Dallas, Texas time) on the third Business Day before the date of the proposed issuance, increase, or extension of the Letter of Credit, and the Administrative Agent shall give to each Lender prompt notice thereof by telex, telephone or telecopy. Each Letter of Credit Application shall be given by hand delivery, telecopier, telex, e-mail, or other electronic transmission, confirmed in writing or other acceptable means to the extent requested, specifying the information required therein. After the applicable Issuing Bank’s receipt of such Letter of Credit Application and upon fulfillment (or waiver in writing) of the applicable conditions set forth in Article III, such Issuing Bank shall issue, increase, or extend such Letter of Credit for the account of the Borrower or any applicable Subsidiary. Each Letter of Credit Application shall be irrevocable and binding on the Borrower.

(d) Reimbursement . The Borrower hereby agrees to pay on demand to the applicable Issuing Bank an amount equal to any amount paid by such Issuing Bank under any Letter of Credit. In the event an Issuing Bank makes a payment pursuant to a request for draw presented under a Letter of Credit and such payment is not promptly reimbursed by the Borrower upon demand, such Issuing Bank shall give the Administrative Agent notice of the Borrower’s failure to make such reimbursement and the Administrative Agent shall promptly notify each Lender of the amount necessary to reimburse such Issuing Bank. Upon such notice from the Administrative Agent, each Lender shall promptly reimburse such Issuing Bank for such Lender’s Pro Rata Share of such amount and such reimbursement shall be deemed for all purposes of this Agreement to be an Advance to the Borrower transferred at the Borrower’s request to such Issuing Bank. If such reimbursement is not made by any Lender to such Issuing Bank on the same day on which the Administrative Agent notifies such Lender to make reimbursement to such Issuing Bank hereunder, such Lender shall pay interest on its Pro Rata

Share thereof to such Issuing Bank at a rate per annum equal to the Federal Funds Rate. The Borrower hereby unconditionally and irrevocably authorizes, empowers, and directs the Administrative Agent and the Lenders to record and otherwise treat such reimbursements to such Issuing Bank as Alternate Base Rate Advances under a Borrowing requested by the Borrower to reimburse such Issuing Bank which have been transferred to such Issuing Bank at the Borrower’s request.

(e) Obligations Unconditional . The obligations of the Borrower under this Agreement in respect of each Letter of Credit shall be unconditional and irrevocable, and shall be paid strictly in accordance with the terms of this Agreement under all circumstances, including, without limitation, the following circumstances:

(i) any lack of validity or enforceability of any Letter of Credit Documents;

(ii) any amendment or waiver of, or any consent to, departure from any Letter of Credit Documents;

(iii) the existence of any claim, set-off, defense, or other right which the Borrower may have at any time against any beneficiary or transferee of such Letter of Credit (or any Persons for whom any such beneficiary or any such transferee may be acting), the applicable Issuing Bank, or any other person or entity, whether in connection with this Agreement, the transactions contemplated in this Agreement or in any Letter of Credit Documents, or any unrelated transaction;

(iv) any statement or any other document presented under such Letter of Credit proving to be forged, fraudulent, invalid, or insufficient in any respect or any statement therein being untrue or inaccurate in any respect to the extent the applicable Issuing Bank would not be liable therefor pursuant to the following Section 2.13(f); or

(v) payment by the applicable Issuing Bank under such Letter of Credit against presentation of a draft or certificate which does not comply with the terms of such Letter of Credit;

provided , however , that nothing contained in this Section 2.13(e) shall be deemed to constitute a waiver of any remedies of the Borrower in connection with the Letters of Credit or the Borrower’s rights under Section 2.13(f) below.

(f) Liability of Issuing Bank . The Borrower assumes all risks of the acts or omissions of any beneficiary or transferee of any Letter of Credit with respect to its use of such Letter of Credit. No Issuing Bank nor any of its officers or directors shall be liable or responsible for:

(i) the use which may be made of any Letter of Credit or any acts or omissions of any beneficiary or transferee in connection therewith;

(ii) the validity, sufficiency, or genuineness of documents, or of any endorsement thereon, even if such documents should prove to be in any or all respects invalid, insufficient, fraudulent, or forged;

(iii) payment by an Issuing Bank against presentation of documents which do not comply with the terms of a Letter of Credit, including failure of any documents to bear any reference or adequate reference to the relevant Letter of Credit; or

(iv) any other circumstances whatsoever in making or failing to make payment under any Letter of Credit (INCLUDING AN ISSUING BANK’S OWN NEGLIGENCE) ,

except that the Borrower shall have a claim against the applicable Issuing Bank, and such Issuing Bank shall be liable to the Borrower to the extent of any direct, as opposed to consequential, damages suffered by the Borrower which the Borrower proves were caused by (A) such Issuing Bank’s willful misconduct, bad faith, or gross negligence in determining whether documents presented under a Letter of Credit comply with the terms of such Letter of Credit or (B) such Issuing Bank’s willful failure to make lawful payment under any Letter of Credit after the presentation to it of a draft and certificate strictly complying with the terms and conditions of such Letter of Credit. In furtherance and not in limitation of the foregoing, such Issuing Bank may accept documents that appear on their face to be in order, without responsibility for further investigation, regardless of any notice or information to the contrary.

(g) Cash Collateral Account .

(i) If the Borrower is required to deposit funds in the Cash Collateral Account pursuant to Sections 2.04(b), 2.13(a), 2.17(a), 2.18(b), 7.02(b), or 7.03(b), then the Borrower and the Administrative Agent shall establish the Cash Collateral Account and the Borrower shall execute any documents and agreements that the Administrative Agent reasonably requests in connection therewith to establish the Cash Collateral Account and grant the Administrative Agent an Acceptable Security Interest in such account and the funds therein. The Borrower hereby pledges to the Administrative Agent and grants the Administrative Agent a security interest in (x) the Cash Collateral Account, whenever established, (y) all funds held in the Cash Collateral Account from time to time, and (z) all proceeds thereof as security for the payment of the Obligations.

(ii) So long as no Event of Default exists, (A) the Administrative Agent may apply the funds held in the Cash Collateral Account only to the reimbursement of any Letter of Credit Obligations, and (B) the Administrative Agent shall promptly release to the Borrower at the Borrower’s written request any funds held in the Cash Collateral Account in an amount up to but not exceeding the excess, if any (immediately prior to the release of any such funds), of the total amount of funds held in the Cash Collateral Account over the Letter of Credit Exposure. During the existence of any Event of Default, the Administrative Agent may apply any funds held in the Cash Collateral Account to the Obligations in any order determined by the Administrative Agent, regardless of any Letter of Credit Exposure which may remain outstanding. The Administrative Agent may in its sole discretion at any time release to the Borrower any funds held in the Cash Collateral Account.

(iii) The Administrative Agent shall exercise reasonable care in the custody and preservation of any funds held in the Cash Collateral Account and shall be deemed to have exercised such care if such funds are accorded treatment substantially equivalent to that which the Administrative Agent accords its own property, it being understood that the Administrative Agent shall not have any responsibility for taking any necessary steps to preserve rights against any parties with respect to any such funds.

Section 2.14. Commitment Increase .

(a) Subject to the conditions set forth in clauses (b) and (c) of this Section 2.14, the Borrower may request that the amount of the aggregate Commitments be increased one or more times, in each case in a minimum amount of $10,000,000 (or such lesser amount as the Administrative Agent approves) and in integral multiples of $5,000,000 (or such lesser amount as the Administrative Agent approves) in excess thereof; provided that , the aggregate Commitments may not exceed $1,700,000,000. No Lender shall have any obligation to increase its Commitment.

(b) Each such increase shall be effective, without the consent of any Lender (other than any Lender increasing its Commitment) only upon the following conditions being satisfied: (i) no Default or Event of Default has occurred and is continuing at the time thereof or would be caused thereby, (ii) either the Lenders having Commitments hereunder at the time the increase is requested agree to increase their Commitments in the amount of the requested increase and/or other financial institutions satisfying the definitions of Eligible Assignee or Approved Affiliate agree to make a Commitment, (iii) such Lenders and other financial institutions, if any, shall have executed and delivered to the Administrative Agent a Commitment Increase Agreement or a New Lender Agreement, as applicable, and (iv) the Borrower shall have delivered such evidence of authority for the increase (including without limitation, certified resolutions of the board of directors or other governing body of the Ultimate General Partner authorizing such increase) as the Administrative Agent may reasonably request.

(c) Each financing institution to be added to this Agreement as described in Section 2.14(b)(ii) above shall execute and deliver to the Administrative Agent a New Lender Agreement, pursuant to which it becomes a party to this Agreement. Each Lender agreeing to increase its Commitment as described in Section 2.14(b)(ii) shall execute and deliver to the Administrative Agent a Commitment Increase Agreement pursuant to which it increases its Commitment hereunder. In addition, a Responsible Officer shall execute and deliver to the Administrative Agent, for each Lender being added to this Agreement, a Note payable to such new Lender in the principal amount of the Commitment of such Lender to the extent a Note is requested by such new Lender, and for each Lender increasing its Commitment, a replacement Note payable to such Lender, in the principal amount of the increased Commitment of such Lender, to the extent such Lender has previously requested a Note. Each such Note (if any) shall be dated the effective date of the pertinent New Lender Agreement or Commitment Increase Agreement. Upon execution and delivery to the Administrative Agent of the Notes, if applicable, and the execution by the Administrative Agent of the relevant New Lender Agreement or Commitment Increase Agreement, as the case may be, such new financing institution shall constitute a “Lender” hereunder with a Commitment as specified therein, or such existing Lender’s Commitment shall increase as specified therein, as the case may be, and (i) any Lender increasing (or, in the case of any newly added Lender, providing) its Commitment shall make available to the Administrative Agent such amounts in immediately available funds as the Administrative Agent shall determine, for the benefit of the other Lenders, as being required in order to cause, after giving effect to such increase or addition and the use of such amounts to make payments to such other Lenders, each Lender’s portion of the outstanding Advances of all the Lenders to equal its revised Pro Rata Share of such outstanding Advances, and the Administrative Agent shall make such other adjustments among the Lenders with respect to the Advances then outstanding and amounts of principal, interest, commitment fees and other amounts paid or payable with respect thereto as shall be necessary, in the opinion of the Administrative Agent, in order to effect such reallocation and (ii) the Borrower shall be deemed to have repaid and reborrowed all outstanding Advances as of the date of any increase (or addition) in the Commitments (with such reborrowing to consist of

the Types of Advances, with related Interest Periods if applicable, specified in a Notice of Borrowing delivered by the Borrower, in accordance with the requirements of  Section 2.02 ). The deemed payments made pursuant to clause  (ii) of the immediately preceding sentence shall be accompanied by payment of all accrued interest on the amount prepaid and, in respect of each Eurodollar Rate Advance, shall be subject to indemnification by the Borrower pursuant to the provisions of  Section 2.10 if the deemed payment occurs other than on the last day of the related Interest Period. Within a reasonable time after the effective date of any increase or addition, the Administrative Agent shall notify all Lenders of such addition or increase, and the final allocations thereof, and provide a revised Schedule 1.01(a) reflecting such additions or increase, whereupon such revised Schedule 1.01(a) shall replace the then-existing Schedule 1.01(a) and become part of this Agreement .

(d) The decision to increase its Commitment hereunder shall be at the sole discretion of each Lender. Any such increase in any Lender’s Commitment shall have the same guarantees as, and be secured on a pari passu basis by the Collateral (if any) securing its Commitment prior to such increase.

Section 2.15. Replacement of Lenders . If the Borrower is required pursuant to Section 2.07(c), 2.11 or 2.12 to make any additional payment to any Lender, or if any Lender’s obligation to make or continue, or to convert Alternate Base Rate Advances into, Eurodollar Rate Advances shall be suspended pursuant to 2.02(c)(ii), 2.02(c)(iv) or 2.04(c), or if any Lender is a Defaulting Lender, a Non-Extending Lender or a Non-Consenting Lender (any Lender so affected, an “ Affected Lender ”), the Borrower may elect, if such amounts continue to be charged or such suspension is still effective, to replace such Affected Lender as a Lender party to this Agreement, provided that (a) no Event of Default shall have occurred and be continuing at the time of such replacement; (b) such replacement shall be at the Borrower’s sole expense and effort, including the payment of the administrative fee referenced in Section 9.06(a); (c) concurrently with such replacement, another bank or other entity (which entity shall be an Eligible Assignee or an Approved Affiliate) shall agree, as of such date, to purchase for cash at par the Advances and other Obligations due to the Affected Lender pursuant to an assignment substantially in the form of Exhibit A and to become a Lender for all purposes under this Agreement and to assume all obligations of the Affected Lender which as to the Affected Lender shall be terminated as of such date and to comply with the requirements of Section 9.06 applicable to assignments; and (d) concurrently with such replacement, the Borrower shall pay to such Affected Lender in same day funds on the day of such replacement all interest, fees and other amounts then accrued but unpaid to such Affected Lender by the Borrower hereunder to and including the date of termination, including without limitation payments due to such Affected Lender under Sections 2.07(c), 2.11 and 2.12, as applicable. 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 Issuing Bank, as applicable, or otherwise, the circumstances entitling the Borrower to require such assignment and delegation cease to apply.

Section 2.16. Pari Passu Lien . All Obligations arising under the Credit Documents, including, without limitation, Obligations under this Agreement, Banking Service Obligations and Obligations under any Lender Hedging Agreement, shall be secured pari passu by the Collateral (if any). For the avoidance of doubt, no Debt of any Excluded Subsidiary owing to any counterparty party to a Swap Contract with any Excluded Subsidiary shall be secured by the Collateral or be considered an “Obligation” for purposes of the Credit Documents. No counterparty to any Lender Hedging Agreement, nor any Lender or Affiliate of a Lender providing Banking Services, shall have any voting rights under any Credit Document as a result of the existence of obligations owed to it under any Lender Hedging Agreement or as a result of any Banking Service Obligation being owed to it, respectively, except as expressly provided herein.

Section 2.17. Defaulting Lenders.

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

(i) Waivers and Amendments . That 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 9.01.

(ii) Reallocation of Payments . Any payment of principal, interest, fees or other amounts received by the Administrative Agent for the account of that Defaulting Lender (whether voluntary or mandatory, at maturity, pursuant to Article VII or otherwise, and including any amounts made available to the Administrative Agent by that Defaulting Lender pursuant to Section 7.05), shall be applied at such time or times as may be determined by the Administrative Agent as follows: first, to the payment of any amounts owing by that Defaulting Lender to the Administrative Agent hereunder; second, to the payment on a pro rata basis of any amounts owing by that Defaulting Lender to the Issuing Banks hereunder; third, if so determined by the Administrative Agent or requested by an Issuing Bank or Borrower, to be held in the Cash Collateral Account for future funding obligations of that Defaulting Lender of any participation in any Letter of Credit; fourth, as the Borrower may request (so long as no Default or Event of Default exists), to the funding of any Advance in respect of which that Defaulting Lender has failed to fund its portion thereof as required by this Agreement, as determined by the Administrative Agent; fifth, if so determined by the Administrative Agent or requested by the Borrower, to be held in a non-interest bearing deposit account and released in order to satisfy obligations of that Defaulting Lender to fund Advances under this Agreement; sixth, to the payment of any amounts owing to the Lenders or the Issuing Banks as a result of any judgment of a court of competent jurisdiction obtained by any Lender or the Issuing Banks against that Defaulting Lender as a result of that Defaulting Lender’s breach of its obligations under this Agreement; seventh, so long as no Default or Event of Default exists, to the payment of any amounts owing to the Borrower as a result of any judgment of a court of competent jurisdiction obtained by the Borrower against that Defaulting Lender as a result of that Defaulting Lender’s breach of its obligations under this Agreement; and eighth, to that Defaulting Lender or as otherwise directed by a court of competent jurisdiction; provided that if (x) such payment is a payment of the principal amount of any Advances or Letter of Credit Obligations in respect of which that Defaulting Lender has not fully funded its appropriate share and (y) such Advances or Letter of Credit Obligations was made at a time when the conditions set forth in Section 3.02 were satisfied or waived, such payment shall be applied solely to pay the Advances of, and Letter of Credit Obligations owed to, all non-Defaulting Lenders on a pro rata basis prior to being applied to the payment of any Advances of, or Letter of Credit Obligations owed to, that Defaulting Lender. Any payments, prepayments or other amounts paid or payable to a Defaulting Lender that are applied (or held) to pay amounts owed by a Defaulting Lender or to deposit into the Cash Collateral Account pursuant to this Section 2.17(a)(ii) shall be deemed paid to and redirected by that Defaulting Lender, and each Lender irrevocably consents hereto.

(iii) Certain Fees . That Defaulting Lender shall not be entitled to receive or accrue any fees pursuant to Section 2.06 for any period during which that Lender is a

Defaulting Lender (and the Borrower shall not be required to pay any such fee that otherwise would have been required to have been paid to that Defaulting Lender).

(iv) Reallocation of Pro Rata Shares to Reduce Letter of Credit Exposure . Subject to this Section 2.17(a)(iv), during any period in which there is a Defaulting Lender, for purposes of computing the amount of the obligation of each non-Defaulting Lender to acquire, refinance or fund participations in Letters of Credit pursuant to Section 2.13, the “Pro Rata Share” of each non-Defaulting Lender shall be computed without giving effect to the Commitment of that Defaulting Lender; provided , that , (i) each such reallocation shall be given effect only if, at the date the applicable Lender becomes a Defaulting Lender, no Default or Event of Default exists; and (ii) the aggregate obligation of each non-Defaulting Lender to acquire, refinance or fund participations in Letters of Credit shall not exceed the positive difference, if any, of (1) the Commitment of that non-Defaulting Lender minus (2) the outstanding amount of Advances of that Lender.

(b) Defaulting Lender Cure . If the Borrower, the Administrative Agent and the Issuing Banks agree in writing in their sole discretion that a Defaulting Lender should no longer be deemed to be 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 deposits to the Cash Collateral Account), that Lender will, to the extent applicable, purchase that portion of outstanding Advances of the other Lenders or take such other actions as the Administrative Agent may determine to be necessary to cause the Advances and funded and unfunded participations in Letters of Credit to be held on a pro rata basis by the Lenders in accordance with their Pro Rata Shares (without giving effect to Section 2.17(a)(iv)), whereupon that 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 Borrower 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) Replacement of Defaulting Lender . The Borrower shall have the right to replace a Defaulting Lender in accordance with Section 2.15.

Section 2.18. Extension of Final Maturity Date .

(a) The Borrower may from time to time, upon written notice to the Administrative Agent (which shall promptly notify the Lenders) (an “ Extension Request ”), request an extension of the Final Maturity Date then in effect with respect to the Commitments existing at the time of such request (the “ Existing Commitments ”, and such Existing Commitments as extended, the “ Extended Commitments ”) to a date specified in such Extension Request. The Extension Request shall specify the date on which the Borrower proposes that the extension shall be effective, which shall be a date reasonably satisfactory to the Administrative Agent (but in no event, shall such date be less than 15 days after the Administrative Agent’s receipt of such Extension Request). Each Lender shall notify the Administrative Agent whether or not it consents to such Extension Request (which consent may be given or withheld in such Lender’s sole and absolute discretion) within the time provided in such Extension Request. Any Lender not responding within the time period shall be deemed not to have consented to such Extension Request. The Administrative Agent shall promptly notify the Borrower and the Lenders of the Lenders’ responses.

(b) The Final Maturity Date shall be extended only if the Majority Lenders (calculated excluding any Defaulting Lender and after giving effect to any replacements of Lenders permitted herein) have consented thereto (the Lenders that so consent being the “ Extending Lenders ” and the Lenders that do not consent being the “ Non-Extending Lenders ”) (it being understood and agreed that, except for the consents of Extending Lenders, no other consents shall be required hereunder for such extensions), and the maturity date of the Commitments shall be extended only with respect to the Existing Commitments held by such Extending Lenders. If so extended, the Final Maturity Date, as to the Extending Lenders, shall be extended to the date set forth in such Extension Request (such existing Final Maturity Date being the “ Extension Effective Date ”). The Administrative Agent and the Borrower shall promptly confirm to the Lenders such extension, specifying the date of such confirmation (the “ Extension Confirmation Date ”), the Extension Effective Date, and the new Final Maturity Date (after giving effect to such extension) with respect to the Extended Commitments. The proposed terms of the Extended Commitments to be established shall be identical as offered to each Lender and be identical to the Existing Commitments from which such Extended Commitments are to be extended, except that: (x) the maturity date of the Extended Commitments shall be later than the maturity date of the Existing Commitments and (y) the Administrative Agent and the Extending Lenders may receive customary fees in consideration for the extension of the Extended Commitments. As a condition precedent to such extension, the Borrower shall deliver to the Administrative Agent a certificate of the Borrower dated as of the Extension Confirmation Date signed by a Responsible Officer of the Borrower (i) certifying and attaching the resolutions adopted by the Borrower approving or consenting to such extension and (ii) certifying that, (A) before and after giving effect to such extension, the representations and warranties contained in Article III made by it are true and correct in all material respects (or, in the case of any such representations and warranties that are qualified as to materiality, the accuracy in all respects of such representations and warranties) on and as of the Extension Confirmation Date, except to the extent that such representations and warranties specifically refer to an earlier date, in which case such representations and warranties shall be true and correct in all material respects (or, in the case of any such representations and warranties that are qualified as to materiality, the accuracy in all respects of such representations and warranties) as of such earlier date, (B) before and after giving effect to such extension no Default exists or will exist as of the Extension Confirmation Date, and (C) since December 31, 2016, no event, development or circumstance that has had or could reasonably be expected to have a Material Adverse Effect has occurred. The Borrower shall prepay any Advances outstanding on the Extension Effective Date (and pay any additional amounts required pursuant to Section 2.10) to the extent necessary to keep outstanding Advances ratable with any revised and new Pro Rata Shares of all the Lenders effective as of the Extension Effective Date; and if, after giving effect to such prepayment, the aggregate outstanding principal amount of Advances plus the aggregate Letter of Credit Exposure exceeds the aggregate Commitments then in effect as a result of a Letter of Credit Exposure, then the Borrower will pay to the Administrative Agent on behalf of the Lenders an amount equal to such excess to be held as cash collateral as provided in Section 2.13(g). In addition, each Extending Lender shall automatically (without any further action) and ratably acquire on the Extension Effective Date the Non-Extending Lenders’ participations in Letters of Credit, in an amount equal to such Extending Lender’s Pro Rata Share of the amount of such participations. Notwithstanding the conversion of any Existing Commitment into an Extended Commitment, such Extended Commitment shall be treated identically to all Existing Commitments for purposes of the obligations of a Lender in respect of Letters of Credit under Section 2.13, except that the applicable Extension Amendment may provide that the last day for issuing Letters of Credit may be extended and the related obligations to issue Letters of Credit may be continued (pursuant to mechanics to be specified in the applicable Extension Amendment) so long as the applicable Issuing Bank has consented to

such extension (it being understood that no consent of any other Lender shall be required in connection with any such extension).

(c) The Borrower shall be permitted to replace any Non-Extending Lender pursuant to Section 2.15.

(d) Notwithstanding the terms of Section 9.01, the Borrower and the Administrative Agent shall be entitled (without the consent of any other Lenders except to the extent required under subsection (b) above) to enter into any amendments (each an “ Extension Amendment ”) to this Agreement, in form and substance satisfactory to the Administrative Agent, that the Administrative Agent reasonably believes are necessary to appropriately reflect, or provide for the integration of, any extension of the maturity date pursuant to this Section 2.18. It is understood and agreed that each Lender hereunder has consented, and shall at the effective time thereof be deemed to consent to each amendment to this Agreement and the other Loan Documents authorized by this Section 2.18 and the arrangements described above in connection therewith. Notwithstanding anything to the contrary in this Section 2.18(d) and without limiting the generality or applicability of Section 9.01 to any Specified Amendments (as defined below), any Extension Amendment may provide for additional terms and/or additional amendments other than those referred to or contemplated above (any such additional amendment, a “ Specified Amendment ”) to this Agreement and the other Credit Documents; provided that such Specified Amendments do not become effective prior to the time that such Specified Amendments have been consented to (including, without limitation, pursuant to consents applicable to holders of any Extended Commitments provided for in any Extension Amendment) by such of the Lenders, Loan Parties and other parties (if any) as may be required in order for such Specified Amendments to become effective in accordance with Section 9.01.

Section 4.04. Enforceable Obligations . This Agreement, the Notes (if any), and the other Credit Documents have been duly executed and delivered by the Borrower and each of the Guarantors to which any of them is a party. Each Credit Document is (or upon execution will be) the legal, valid, and binding obligation of the Borrower and each of the Guarantors enforceable against the Borrower and each of the Guarantors in accordance with its terms, except for the Third Party Consent Limitation with respect to real property interests to which such limitation is applicable and except as such enforceability may be limited by any applicable bankruptcy, insolvency, reorganization, moratorium, or similar law affecting creditors’ rights generally and general equitable principles (whether considered in a proceeding in equity or at law).

Section 4.05. Financial Statements . The Borrower has delivered to the Administrative Agent and the Lenders copies of the Financial Statements, and the Financial Statements are accurate and complete in all material respects and present fairly the consolidated financial condition of the Borrower and its consolidated Subsidiaries as of their respective dates and for their respective periods in accordance with GAAP. As of the date of the Financial Statements, there were no material contingent obligations, liabilities for taxes, unusual forward or long term commitments, or unrealized or anticipated losses of the Borrower or any of its Subsidiaries, except for the Third Party Consent Limitation with respect to real property interests to which such limitation is applicable and except as disclosed therein and adequate reserves for such items have been made in accordance with GAAP. All projections, estimates, and pro forma financial information furnished by the Borrower were prepared on the basis of assumptions, data, information, tests, or conditions believed to be reasonable at the time such projections, estimates, and pro forma financial information were furnished. Since the date of the Financial Statements, no Material Adverse Effect has occurred, and no event or circumstance that could reasonably be expected to cause a Material Adverse Effect has occurred.

Section 4.06. True and Complete Disclosure . All factual information heretofore or contemporaneously furnished by or on behalf of the Borrower, any of its Subsidiaries or any Holdco Entity in writing to the Administrative Agent and the Lenders for purposes of or in connection with this Agreement, any other Credit Document, or any transaction contemplated hereby or thereby is, and all other such factual information (taken as a whole) hereafter furnished by or on behalf of the Borrower, any of its Subsidiaries or any Holdco Entity in writing to the Administrative Agent and the Lenders will be, true and accurate in all material respects on the date as of which such information is dated or certified and not incomplete by omitting to state any material fact necessary to make such information (taken as a whole) not misleading at such time.

Section 4.07. Litigation . Except as set forth on Schedule 4.07 , there is no pending or, to the best knowledge of the Borrower or any of its Subsidiaries, threatened action or proceeding against the Borrower, any of its Subsidiaries or any Holdco Entity before any court, Governmental Authority or arbitrator, including, without limitation, the FERC or any equivalent state regulatory agency, which could

reasonably, individually or in the aggregate, be expected to have a Material Adverse Effect or which purports to affect the legality, validity, binding effect or enforceability of this Agreement, the Notes, or any other Credit Document. Additionally, there is no pending or, to the knowledge of any Responsible Officer, threatened action or proceeding instituted against the Borrower, any of its Subsidiaries or any Holdco Entity which seeks to adjudicate the Borrower, any of its Subsidiaries or any Holdco Entity as bankrupt or insolvent, or seeking liquidation, winding up, reorganization, arrangement, adjustment, protection, relief, or composition of it or its debts under any law relating to bankruptcy, insolvency or reorganization or relief of debtors, or seeking the entry of an order for relief or the appointment of a receiver, trustee or other similar official for it or for any substantial part of its Property other than a threatened action or involuntary proceeding that is not an Event of Default pursuant to Section 7.01(e).

Section 4.08. Use of Proceeds . The proceeds of the Borrowings will be used by the Borrower for (i) working capital purposes of the Borrower, any Guarantor and their Subsidiaries, (ii) Investments, Acquisitions and the development of new projects, including, without limitation, any Capital Expansion Projects, (iii) general corporate purposes of the Borrower, any Guarantor and their Subsidiaries including, without limitation, the making of capital expenditures, (iv) to refinance Debt existing under the Prior Credit Agreement, (v) payment of the fees and expenses incurred in connection with the refinancing of the Debt existing under the Prior Credit Agreement, (vi) the making of Distribution Payments in compliance with Section 6.05 and (vii) the repayment or repurchase of Debt in compliance with Section 6.05, including the Permitted Note Debt. Borrower shall use all Letters of Credit for its, its Subsidiaries’ and any Holdco Entity’s lawful business purposes.

Section 4.09. Investment Company Act . None of the Borrower or any of its Subsidiaries or any Holdco Entity is an “investment company” or a company “controlled” by an “investment company” within the meaning of the Investment Company Act of 1940, as amended.

Section 4.10. Taxes . All federal, and material state, local and foreign tax returns, reports and statements required to be filed (after giving effect to any extension granted in the time for filing) by the Borrower or any member of the Controlled Group (hereafter collectively called the “ Tax Group ”) have been filed with the appropriate Governmental Authority in all jurisdictions in which such returns, reports, and statements are required to be filed, and all taxes (which are material in amount) and other impositions due and payable have been timely paid prior to the date on which any fine, penalty, interest, late charge or loss may be added thereto for non-payment thereof except (a) where contested in good faith and by appropriate proceedings or (b) to the extent the failure to pay such, individually or in the aggregate, could not reasonably be expected to have a Material Adverse Effect. Neither the Borrower nor any member of the Tax Group has given, or been requested to give, a waiver of the statute of limitations relating to the payment of any federal, state, local or foreign taxes or other impositions. Proper and accurate amounts have been withheld by the Borrower and all other members of the Tax Group from their employees for all periods to comply in all material respects with the tax, social security and unemployment withholding provisions of applicable federal, state, local and foreign law. Timely payment of all sales and use taxes required by applicable law have been made by the Borrower and all other members of the Tax Group, except to the extent that the failure to pay such, individually or in the aggregate, could not reasonably be expected to have a Material Adverse Effect.

Section 4.11. Pension Plans; ERISA . All Plans are in compliance in all material respects with all applicable provisions of ERISA. No Termination Event has occurred with respect to any Plan, and each Plan has complied with and been administered in all material respects in accordance with applicable provisions of ERISA and the Code. No “accumulated funding deficiency” (as defined in Section 302 of ERISA) has occurred and there has been no excise tax imposed under Section 4971 of the Code. No Reportable Event has occurred with respect to any Multiemployer Plan, and each Multiemployer Plan has complied with and been administered in all material respects with applicable provisions of ERISA and the

Code. Neither the Borrower nor any member of the Controlled Group has had a complete or partial withdrawal from any Multiemployer Plan for which there is any withdrawal liability. As of the most recent valuation date applicable thereto, neither the Borrower nor any member of the Controlled Group would become subject to any liability under ERISA if the Borrower or any member of the Controlled Group has received notice that any Multiemployer Plan is insolvent or in reorganization. Based upon GAAP existing as of the date of this Agreement and current factual circumstances, the Borrower has no reason to believe that the annual cost during the term of this Agreement to the Borrower or any member of the Controlled Group for post-retirement benefits to be provided to the current and former employees of the Borrower or any member of the Controlled Group under Plans that are welfare benefit plans (as defined in Section 3(1) of ERISA) could, in the aggregate, reasonably be expected to cause a Material Adverse Effect. The Borrower represents and warrants as of the Effective Date that the Borrower is not and will not be (1) an employee benefit plan subject to Title I of ERISA, (2) a plan or account subject to Section 4975 of the Code; (3) an entity deemed to hold “plan assets” of any such plans or accounts for purposes of ERISA or the Code; or (4) a “governmental plan” within the meaning of ERISA.

Section 4.12. Insurance . The Borrower and its Subsidiaries and the Holdco Entities carry the insurance required to be carried under Section 5.02 of this Agreement.

Section 4.13. No Burdensome Restrictions; No Defaults . None of the Borrower, any of its Subsidiaries, or any Holdco Entity is a party to any indenture, loan or credit agreement or any lease or other agreement or instrument or subject to any charter or partnership restriction or provision of any Legal Requirement which could reasonably, individually or in the aggregate, be expected to have a Material Adverse Effect or which could affect the legality, validity, binding effect or enforceability of this Agreement, the Notes (if any), or any other Credit Document. Except as set forth on Schedule 4.13 , none of the Borrower, any of its Subsidiaries, or any Holdco Entity is in default under or with respect to any Material Contract to which the Borrower, any of its Subsidiaries, or any Holdco Entity is a party.

Section 4.14. Environmental Condition . Except for matters that, individually or in the aggregate, (i) do not materially interfere with the ordinary conduct of Business, (ii) do not materially detract from the value or the use of the portion of the Pipeline Systems affected thereby and (iii) could not reasonably be expected to have a Material Adverse Effect:

(a) Permits, Etc. The Borrower and each of its Subsidiaries and each Holdco Entity (i) have obtained all Environmental Permits necessary for the ownership and operation of its real properties and the conduct of its Business; (ii) have been and are in compliance with all terms and conditions of such Environmental Permits and with all other requirements of applicable Environmental Laws; (iii) have not received written notice of any violation or alleged violation of any Environmental Law or Environmental Permit; and (iv) are not subject to any actual or contingent Environmental Claim.

(b) Certain Liabilities . None of the present or previously owned or operated real properties of the Borrower and each of its Subsidiaries and each Holdco Entity wherever located, (i) are on or, to the Borrower’s knowledge, are proposed to be placed on the National Priorities List, the Comprehensive Environmental Response Compensation Liability Information System list, or their state or local analogs, or are otherwise designated, listed, or identified or, to the knowledge of the Borrower or any of its Subsidiaries, investigated as a potential site for removal, remediation, cleanup, closure, restoration, reclamation, or other response activity under any Environmental Laws; (ii) are subject to a Lien, arising under or in connection with any Environmental Laws, that attaches to any revenues or to any real property owned or operated by the Borrower or any of its Subsidiaries or any Holdco Entity wherever located; or (iii) have been the site of any Release of Hazardous Substances from present or past operations which has caused

at the site or at any third-party site any condition that has resulted in or could reasonably be expected to result in the need for any Response.

(c) Certain Actions . Without limiting the foregoing, (i) all necessary notices have been properly filed, and no further action is required under current Environmental Law as to each Response or other restoration or remedial project taken by the Borrower or any of its Subsidiaries or any Holdco Entity on any of their presently or formerly owned or operated real property and (ii) there is no material present and future liability, if any, of the Borrower and its Subsidiaries or any Holdco Entity which could reasonably be expected to arise in connection with requirements under Environmental Laws. None of the Borrower or any of its Subsidiaries and, to the Borrower’s knowledge, none of the Holdco Entities has knowingly or willfully permitted the commission of waste or other injury or released Hazardous Substances on or about owned or operated property in violation of applicable Environmental Laws.

Section 4.15. Permits, Licenses, etc . The Borrower and each of its Subsidiaries and each Holdco Entity possesses all material authorizations, permits, licenses, patents, patent rights or licenses, trademarks, trademark rights, trade names rights and copyrights which are necessary to conduct the Business. Each of the Borrower and its Subsidiaries and each Holdco Entity manages and operates its business in all material respects in accordance with all applicable Legal Requirements, except where such failure to comply, either individually or in the aggregate, could not reasonably have a Material Adverse Effect. No violations exist or have been recorded in respect of such authorizations, permits, licenses, patents, patent rights or licenses, trademarks, trademark rights, trade names rights and copyrights, including, without limitation, any known conflict with the valid trademarks, trade names, copyrights or licenses of others which could, individually or in the aggregate, have a Material Adverse Effect.

Section 4.16. Security Interests . As of the Effective Date, each of the Borrower and the Guarantors listed on Schedule 4.16 is a “transmitting utility” within the meaning of Section 9.501(b) of the Delaware Uniform Commercial Code. On the date of this Agreement, all governmental actions and all other filings, recordings, registrations, third party consents and other actions which are necessary to create and perfect the Liens provided for in the Security Documents will have been made, obtained and taken in all relevant jurisdictions, or satisfactory arrangements will have been made for all governmental actions and all other filings, recordings, registrations, third party consents, and other actions which are necessary to create and perfect the Liens provided for in the Security Documents to be made, obtained, or taken in all relevant jurisdictions.

Section 4.17. Title, Etc.

(a) The Borrower and each of its Subsidiaries and each Holdco Entity have good and marketable title, in all material respects, in all of their respective Property, including, without limitation, the real and personal property described in each of the Mortgages, as is necessary to operate the Business as reflected in the Financial Statements, and none of such Property is subject to any Lien, except Permitted Liens.

(b) The Pipeline Systems are covered by recorded fee deeds, rights of way, easements, leases, subleases, servitudes, permits, licenses, or other instruments (collectively, “ rights of way ”) in favor of the Borrower or its Subsidiaries (or their predecessors in interest) and their respective successors and assigns, except where the failure of the Pipeline Systems to be so covered, individually or in the aggregate, (i) does not materially interfere with the ordinary conduct of Business, (ii) does not materially detract from the value or the use of the portion of the

Pipeline Systems which are not covered and (iii) could not reasonably be expected to have a Material Adverse Effect. The rights of way establish a contiguous and continuous right of way for the Pipeline Systems and grant the Borrower or its Subsidiaries (or their predecessors in interest) the right to construct, operate, and maintain the Pipeline Systems in, over, under, or across the land covered thereby in the same way that a prudent owner and operator would inspect, operate, repair, and maintain similar assets and in the same way as the Borrower has inspected, operated, repaired, and maintained the Pipeline Systems as reflected in the Financial Statements; provided , however , (A) some of the rights of way granted to the Borrower or its Subsidiaries (or their predecessors in interest) by private parties and Governmental Authorities are revocable at the right of the applicable grantor, (B) some of the rights of way cross properties that are subject to liens in favor of third parties that have not been subordinated to the rights of way; and (C) some rights of way are subject to certain defects, limitations and restrictions; provided , further , none of the limitations, defects, and restrictions described in clauses (A), (B) and (C) above, individually or in the aggregate, (x) materially interfere with the ordinary conduct of Business, (y) materially detract from the value or the use of the portion of the Pipeline Systems which are covered or (z) could reasonably be expected to have a Material Adverse Effect.

(c) The Terminals are covered by fee deeds, real property leases, or other instruments (collectively “ deeds ”) in favor of the Borrower or its Subsidiaries (or their predecessors in interest) and their respective successors and assigns. The deeds grant the Borrower or its Subsidiaries (or their predecessors in interest) the right to construct, operate, and maintain the Terminals in, over, under, and across the land covered thereby in the same way that a prudent owner and operator would inspect, operate, repair, and maintain similar assets and in the same way as the Borrower has inspected, operated, repaired, and maintained the Terminals as reflected in the Financial Statements.

The rights of way and deeds (to the extent applicable) are in full force and effect in all material respects and are valid and enforceable against the parties thereto in accordance with their terms (subject to the effect of any applicable bankruptcy, reorganization, insolvency, moratorium, fraudulent transfer, fraudulent conveyance or similar laws effecting creditors’ rights generally and subject, as to enforceability to the effect of general principles of equity) and all rental and other payments due thereunder by the Borrower, its Subsidiaries, and their predecessors in interest have been duly paid in accordance with the terms of the deeds and rights of way (as such terms are defined in this Section 4.17) except to the extent that a failure to do so, individually or in the aggregate, (x) does not materially interfere with the ordinary conduct of Business, (y) does not materially detract from the value or the use of the portion of the Pipeline Systems covered thereby and (z) could not reasonably be expected to have a Material Adverse Effect.

(e) The Pipeline Systems are located within the confines of the rights of way and do not encroach upon any adjoining property in any one or more material respects. The Terminals

are located within the boundaries of the property affected by the deeds, leases or other instruments to the Borrower or its Subsidiaries and do not encroach upon any adjoining property in any one or more material respects. The buildings and improvements owned or leased by the Borrower and its Subsidiaries, and the operation and maintenance thereof, do not (i) contravene any applicable zoning or building law or ordinance or other administrative regulation or (ii) violate any applicable restrictive covenant or any Legal Requirement, the contravention or violation of which would materially affect the use of the property subject thereto.

(g) No eminent domain proceeding or taking has been commenced or, to the knowledge of the Borrower or any of its Subsidiaries, is contemplated with respect to all or any portion of the Pipeline Systems or the Terminals except for that which, individually or in the aggregate, could not reasonably be expected to have a Material Adverse Effect.

Except as set forth on Schedule 4.18(a) or which could not reasonably be expected to cause a Material Adverse Effect, neither the Borrower, the Parent, any of the Borrower’s Subsidiaries, nor any other Affiliate that now owns or has owned an interest in any of the Interstate Pipelines has been or is the subject of a complaint, investigation or other proceeding regarding their respective rates or practices with respect to the Interstate Pipelines.

(b) With respect to those certain intrastate common carrier pipeline operations that comprise a portion of the Pipeline Systems, as of the Effective Date, such pipeline operations in the State of Texas (the “ Texas Intrastate Pipelines ”) are subject to regulation by the Railroad Commission of Texas.

To the Borrower’s knowledge, the rates charged by Borrower and its Subsidiaries with respect to the Texas Intrastate Pipelines, as

reflected in the Financial Statements, provide no more than a fair return on the aggregate value of the property used to render services on the Texas Intrastate Pipelines, and to the Borrower’s knowledge, neither Borrower nor any of its Subsidiaries uses, charges, imposes, or implements, or has previously done any of the foregoing in a discriminatory way. As of the Effective Date, the Borrower’s and its Subsidiaries’ pipeline operations in the State of Idaho and in the State of New Mexico do not constitute intrastate common carrier pipeline operations and are not subject to regulation by the Idaho Public Utilities Commission or the New Mexico Public Regulation Commission. Except as set forth on Schedule 4.18(b) , neither the Borrower, the Parent, any of the Borrower’s Subsidiaries, nor any other Affiliate that now owns or has owned an interest in any of the Texas Intrastate Pipelines has been or is the subject of a complaint, investigation or other proceeding regarding their respective rates or practices with respect to the Texas Intrastate Pipelines.

(b) The Borrower does not intend to, or to permit any of its Subsidiaries or any Holdco Entity to, and does not believe that it or any of its Subsidiaries or any Holdco Entity will, incur debts beyond its ability to pay such debts as they mature, taking into account the timing of and amounts of cash to be received by it or any such Subsidiary or such Holdco Entity and the timing of the amounts of cash to be payable on or in respect of its Debt or the Debt of such Subsidiary or such Holdco Entity.

Further, Administrative Agent may rely on certifications and representations from the Borrower in determining the existence and amount of such Excluded Pari Passu Hedging Obligations.

ARTICLE VIII

THE ADMINISTRATIVE AGENT AND THE ISSUING BANKS

Section 8.01. Appointment and Authorization of Administrative Agent .

(a) Each Lender hereby irrevocably (subject to Section 8.10) appoints, designates and authorizes the Administrative Agent to take such action on its behalf under the provisions of this Agreement and each other Credit Document and to exercise such powers and perform such duties as are expressly delegated to it by the terms of this Agreement or any other Credit Document, together with such powers as are reasonably incidental thereto. Notwithstanding any

provision to the contrary contained elsewhere herein or in any other Credit Document, the Administrative Agent shall not have any duties or responsibilities, except those expressly set forth herein, nor shall the Administrative Agent have or be deemed to have any fiduciary relationship with any Lender or participant, and no implied covenants, functions, responsibilities, duties, obligations or liabilities shall be read into this Agreement or any other Credit Document or otherwise exist against the Administrative Agent. Without limiting the generality of the foregoing sentence, the use of the term “ agent ” herein and in the other Credit Documents with reference to the Administrative Agent, any syndication agent or documentation agent is not intended to connote any fiduciary or other implied (or express) obligations arising under agency doctrine of any applicable law. Instead, such term is used merely as a matter of market custom, and is intended to create or reflect only an administrative relationship between independent contracting parties.

(b) Each Issuing Bank shall act on behalf of the Lenders with respect to any Letters of Credit issued by it and the documents associated therewith until such time (and except for so long) as the Administrative Agent may agree at the request of the Majority Lenders to act for such Issuing Bank with respect thereto; provided , however , that each Issuing Bank shall have all of the benefits and immunities (i) provided to the Administrative Agent in this Article VIII with respect to any acts taken or omissions suffered by an Issuing Bank in connection with Letters of Credit issued by it or proposed to be issued by it and the application and agreements for letters of credit pertaining to the Letters of Credit as fully as if the term “Administrative Agent” as used in this Article VIII included each Issuing Bank with respect to such acts or omissions, and (ii) as additionally provided herein with respect to each Issuing Bank.

Section 8.02. Delegation of Duties . The Administrative Agent may execute any of its duties under this Agreement or any other Credit Document by or through agents, sub-agents, employees or attorneys-in-fact and shall be entitled to advice of counsel and other consultants or experts concerning all matters pertaining to such duties. Administrative Agent shall not be responsible for the negligence or misconduct of any agent or attorney-in-fact that it selects in the absence of gross negligence, bad faith, or willful misconduct.

Section 8.03. Default; Collateral .

(a) Upon the occurrence and continuance of a Default or Event of Default, the Lenders agree to promptly confer in order that Majority Lenders or all Lenders, as the case may be, may agree upon a course of action for the enforcement of the rights of the Lenders; and the Administrative Agent shall be entitled to refrain from taking any action (without incurring any liability to any Person for so refraining) unless and until the Administrative Agent shall have received instructions from Majority Lenders or all Lenders, as the case may be. All rights of action under the Credit Documents and all right to the Collateral, if any, hereunder may be enforced by the Administrative Agent and any suit or proceeding instituted by the Administrative Agent in furtherance of such enforcement shall be brought in its name as the Administrative Agent without the necessity of joining as plaintiffs or defendants any other Lender, and the recovery of any judgment shall be for the benefit of the Lenders (and, with respect to Lender Hedging Agreements, the counterparties thereto and, with respect to Banking Services, Affiliates of Lenders) subject to the expenses of the Administrative Agent. In actions with respect to any property of the Borrower or any Guarantor, the Administrative Agent is acting for the ratable benefit of each Lender (and, with respect to Lender Hedging Agreements, the counterparties thereto and, with respect to Banking Services, Affiliates of Lenders). Any and all agreements to subordinate (whether made heretofore or hereafter) other indebtedness or obligations of Borrower to the Obligations shall be construed as being for the ratable benefit of each Lender (and, with respect to Lender Hedging Agreements, the counterparties thereto and, with respect to Banking Services, Affiliates of Lenders).

(b) Each Lender authorizes and directs the Administrative Agent to enter into the Security Documents on behalf of and for the benefit of the Lenders (and, with respect to Lender Hedging Agreements, the counterparties thereto and, with respect to Banking Services, Affiliates of Lenders) (or if previously entered into, hereby ratifies the Administrative Agent’s (or any predecessor administrative agent’s) previously entering into such agreements and Security Documents).

(c) Except to the extent unanimity (or other percentage set forth in Section 9.01) is required hereunder, each Lender agrees that any action taken by the Majority Lenders in accordance with the provisions of the Credit Documents, and the exercise by the Majority Lenders of the power set forth herein or therein, together with such other powers as are reasonably incidental thereto, shall be authorized and binding upon all of the Lenders and Affiliates of Lenders (with respect to Banking Service Obligations) and counterparties to Lender Hedging Agreements (with respect to Lender Hedging Agreements).

(d) The Administrative Agent is hereby authorized on behalf of the Lenders, without the necessity of any notice to or further consent from any Lender, from time to time to take any action with respect to any Collateral or Security Documents, if any, which may be necessary to perfect and maintain perfected the Liens upon the Collateral granted pursuant to the Security Documents.

(e) The Administrative Agent shall not have any obligation whatsoever to any Lender or to any other Person to assure that the Collateral exists or is owned by the Person purporting to own it or is cared for, protected, or insured or has been encumbered or that the Liens granted to the Administrative Agent (or any predecessor administrative agent) herein or pursuant thereto have been properly or sufficiently or lawfully created, perfected, protected, or enforced, or are entitled to any particular priority, or to exercise at all or in any particular manner or under any duty of care, disclosure, or fidelity, or to continue exercising, any of the rights granted or available to the Administrative Agent in this Section 8.03 or in any of the Security Documents; IT BEING UNDERSTOOD AND AGREED THAT IN RESPECT OF THE C OLLATERAL , OR ANY ACT , OMISSION , OR EVENT RELATED THERETO , THE A DMINISTRATIVE A GENT MAY ACT IN ANY MANNER IT MAY DEEM APPROPRIATE , IN ITS SOLE DISCRETION , GIVEN THE A DMINISTRATIVE A GENT ’ S OWN INTEREST IN THE C OLLATERAL AS ONE OF THE L ENDERS AND THAT THE A DMINISTRATIVE A GENT SHALL HAVE NO DUTY OR LIABILITY WHATSOEVER TO ANY L ENDER ( AND , WITH RESPECT TO L ENDER H EDGING A GREEMENTS , THE COUNTERPARTIES THERETO AND , WITH RESPECT TO BANKING SERVICES , A FFILIATES OF L ENDERS ), OTHER THAN TO ACT WITHOUT GROSS NEGLIGENCE , BAD FAITH , OR WILLFUL MISCONDUCT .

(f) The Lenders hereby irrevocably authorize the Administrative Agent, at its option and in its discretion, to (i) deliver instruments of assurance confirming the non-existence of any Lien under the Credit Documents with respect to assets of a Person described in Section 5.11 that are excluded from the Collateral and (ii) release any Lien granted to or held by the Administrative Agent upon any Collateral: (A) constituting Property in which neither Borrower nor any Guarantor owned an interest at the time the Lien was granted or at any time thereafter; (B) constituting Property leased to the Borrower or a Guarantor under a lease which has expired or been terminated in a transaction permitted under the Credit Documents or is about to expire and which has not been, and is not intended by the Borrower or such Guarantor to be, renewed; (C)

consisting of an instrument or other possessory collateral evidencing Debt or other obligations pledged to the Administrative Agent (for the benefit of the Lenders), if the Debt or obligations evidenced thereby has been paid in full or otherwise superseded; (D) Property permitted to be sold pursuant to Section 6.04; (E) Property permitted to be invested pursuant to Section 6.06; (F) upon the Investment Grade Date; or (G) upon termination of the Commitments and payment in full of the Obligations (other than the Unliquidated Obligations). In addition, the Lenders irrevocably authorize the Administrative Agent to release Liens upon Collateral as contemplated herein or in any other Credit Document, or if approved, authorized, or ratified in writing by the requisite Lenders. Upon request by the Administrative Agent at any time, the Lenders will confirm in writing the Administrative Agent’s authority to release particular types or items of Collateral pursuant to this Section 8.03.

(g) In furtherance of the authorizations set forth in this Section 8.03, each Lender hereby irrevocably appoints the Administrative Agent its attorney-in-fact, with full power of substitution, for and on behalf of and in the name of each such Lender (i) to enter into Security Documents (including, without limitation, any appointments of substitute trustees under any Security Documents), (ii) to take action with respect to the Collateral and Security Documents, if any, to perfect, maintain, and preserve Lenders’ Liens, and (iii) to execute instruments of release or to take other action necessary to release Liens upon any Collateral to the extent authorized in paragraph (f) hereof. This power of attorney shall be liberally, not restrictively, construed so as to give the greatest latitude to the Administrative Agent’s power, as attorney-in-fact, relative to the Collateral matters described in this Section 8.03. The powers and authorities herein conferred on the Administrative Agent may be exercised by the Administrative Agent through any Person who, at the time of the execution of a particular instrument, is an officer of the Administrative Agent (or any Person acting on behalf of the Administrative Agent pursuant to a valid power of attorney). The power of attorney conferred by this Section 8.03(g) to the Administrative Agent is granted for valuable consideration and is coupled with an interest and is irrevocable so long as the Obligations, or any part thereof, shall remain unpaid or the Lenders are obligated to make any Advance or issue any Letter of Credit under the Credit Documents.

Section 8.04. Liability of Administrative Agent . NO AGENT-RELATED PERSON SHALL (A) BE LIABLE FOR ANY ACTION TAKEN OR OMITTED TO BE TAKEN BY ANY OF THEM UNDER OR IN CONNECTION WITH THIS AGREEMENT OR ANY OTHER CREDIT DOCUMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY (EXCEPT FOR ITS OWN GROSS NEGLIGENCE, BAD FAITH, OR WILLFUL MISCONDUCT IN CONNECTION WITH ITS DUTIES EXPRESSLY SET FORTH HEREIN), or (b) be responsible in any manner to any Lender or participant for any recital, statement, representation or warranty made by Borrower or any Guarantor or any officer thereof, contained herein or in any other Credit Document, or in any certificate, report, statement or other document referred to or provided for in, or received by Administrative Agent under or in connection with, this Agreement or any other Credit Document, or the validity, effectiveness, genuineness, enforceability or sufficiency of this Agreement or any other Credit Document, or for the creation, perfection or priority of any Liens purported to be created by any of the Credit Documents, or the validity, genuineness, enforceability, existence, value or sufficiency of any collateral security, or to make any inquiry respecting the performance by the Borrower of its obligations hereunder or under any other Credit Document, or for any failure of Borrower or any Guarantor or any other party to any Credit Document to perform its obligations hereunder or thereunder. No Agent-Related Person shall be under any obligation to any Lender or participant to ascertain or to inquire as to the observance or performance of any of the agreements contained in, or conditions of, this Agreement or any other Credit Document, or to inspect the properties, books or records of the Borrower or any Guarantor or any Affiliate thereof. No Agent-Related Person shall be responsible for or have any duty to ascertain or inquire into the utilization of any Issuing Bank’s Letter of Credit Commitment (it being understood and agreed that each Issuing Bank shall monitor compliance with its own Letter of Credit Commitment without any further action by the Administrative Agent).

Section 8.05. Reliance by Administrative Agent .

(a) The Administrative Agent shall be entitled to rely, and shall be fully protected in relying, upon any writing, communication, signature, resolution, representation, notice, consent, certificate, affidavit, letter, telegram, facsimile, electronic mail, telex or telephone message, statement or other document or conversation believed by it to be genuine and correct and to have been signed, sent or made by the proper Person or Persons, and upon advice and statements of legal counsel (including counsel to the Borrower or any Guarantor), independent accountants and other experts selected by the Administrative Agent. The Administrative Agent shall be fully justified in failing or refusing to take any action under any Credit Document unless it shall first receive such advice or concurrence of the requisite Majority Lenders as it deems appropriate and, if it so requests, it shall first be indemnified to its satisfaction by the Lenders against any and all liability and expense which may be incurred by it by reason of taking or continuing to take any such action. The Administrative Agent shall in all cases be fully protected in acting, or in refraining from acting, under this Agreement or any other Credit Document in accordance with a request or consent of the requisite Majority Lenders or all the Lenders, if required hereunder, and such request and any action taken or failure to act pursuant thereto shall be binding upon all the Lenders and participants. Where this Agreement expressly permits or prohibits an action unless the requisite Majority Lenders otherwise determine, the Administrative Agent shall, and in all other instances, the Administrative Agent may, but shall not be required to, initiate any solicitation for the consent or a vote of the requisite Lenders.

(b) For purposes of determining compliance with the conditions specified in Section 4.01, each Lender that has funded its Pro Rata Share of the initial Advance on the Effective Date (or, if there is no Advance made on such date, each Lender other than Lenders who gave written objection to the Administrative Agent prior to such date) shall be deemed to have consented to, approved or accepted or to be satisfied with, each document or other matter either sent by the Administrative Agent to such Lender (or otherwise made available for such Lender on SyndTrak Online, DXSyndicate™ or any similar website) for consent, approval, acceptance or satisfaction, or required hereunder to be consented to or approved by or acceptable or satisfactory to a Lender.

Section 8.06. Notice of Default . The Administrative Agent shall not be deemed to have knowledge or notice of the occurrence of any Default or Event of Default, except with respect to defaults in the payment of principal, interest and fees required to be paid to the Administrative Agent for the account of the Lenders, unless the Administrative Agent shall have received written notice from a Lender or the Borrower referring to this Agreement, describing such Default or Event of Default and stating that such notice is a “notice of default.” The Administrative Agent will notify the Lenders of its receipt of any such notice. The Administrative Agent shall take such action with respect to such Default or Event of Default as may be directed by the Majority Lenders in accordance with this Article VIII; provided , however , that unless and until the Administrative Agent has received any such direction, the Administrative Agent may (but shall not be obligated to) take such action, or refrain from taking such action, with respect to such Default or Event of Default as it shall deem advisable or in the best interest of the Lenders.

Section 8.07. Credit Decision; Disclosure of Information by Administrative Agent . Each Lender acknowledges that no Agent-Related Person has made any representation or warranty to it, and that no act by the Administrative Agent hereinafter taken, including any consent to and acceptance of any assignment or review of the affairs of the Borrower or any Guarantor or any Affiliate thereof, shall be

deemed to constitute any representation or warranty by any Agent-Related Person to any Lender as to any matter, including whether Agent-Related Persons have disclosed material information in their possession. Each Lender represents to the Administrative Agent that it has, independently and without reliance upon any Agent-Related Person and based on such documents and information as it has deemed appropriate, made its own appraisal of and investigation into the business, prospects, operations, property, financial and other condition and creditworthiness of the Borrower, any Guarantor and their respective Subsidiaries, and all applicable bank or other regulatory laws relating to the transactions contemplated hereby, and made its own decision to enter into this Agreement and to extend credit to the Borrower hereunder. Each Lender also represents that it will, independently and without reliance upon any Agent-Related Person and based on such documents and information as it shall deem appropriate at the time, continue to make its own credit analysis, appraisals and decisions in taking or not taking action under this Agreement and the other Credit Documents, and to make such investigations as it deems necessary to inform itself as to the business, prospects, operations, property, financial and other condition and creditworthiness of the Borrower and the other Loan Parties. In this regard, each Lender acknowledges that Thompson & Knight LLP is acting in this transaction as counsel to the Administrative Agent. Each other party hereto will consult with its own legal counsel to the extent that it deems necessary in connection with the Credit Documents and the matters contemplated therein. Except for notices, reports and other documents expressly required to be furnished to the Lenders by the Administrative Agent herein, the Administrative Agent shall not have any duty or responsibility to provide any Lender with any credit or other information concerning the business, prospects, operations, property, financial and other condition or creditworthiness of any of the Loan Parties or any of their respective Affiliates which may come into the possession of any Agent-Related Person.

Section 8.08. Indemnification of Agents . W HETHER OR NOT THE TRANSACTIONS CONTEMPLATED HEREBY ARE CONSUMMATED , THE L ENDERS SHALL INDEMNIFY UPON DEMAND EACH A GENT -R ELATED P ERSON ( TO THE EXTENT NOT REIMBURSED BY OR ON BEHALF OF THE B ORROWER AND WITHOUT LIMITING THE OBLIGATION OF B ORROWER TO DO SO ), IN ACCORDANCE WITH THEIR RESPECTIVE P RO R ATA S HARES , AND ALSO IN ACCORDANCE WITH SUCH P RO R ATA S HARES , HOLD HARMLESS EACH A GENT -R ELATED P ERSON FROM AND AGAINST ANY AND ALL INDEMNIFIED LIABILITIES INCURRED BY IT ( INCLUDING SUCH A GENT -R ELATED P ERSON ’ S OWN NEGLIGENCE ); PROVIDED , HOWEVER , THAT NO L ENDER SHALL BE LIABLE FOR THE PAYMENT TO ANY A GENT -R ELATED P ERSON OF ANY PORTION OF SUCH INDEMNIFIED LIABILITIES RESULTING FROM SUCH P ERSON ’ S GROSS NEGLIGENCE , BAD FAITH , OR WILLFUL MISCONDUCT ; provided , however , that no action taken in accordance with the directions of the Majority Lenders shall be deemed to constitute gross negligence, bad faith, or willful misconduct for purposes of this Section 8.08. Without limitation of the foregoing, each Lender shall reimburse the Administrative Agent upon demand for its ratable share of any costs or reasonable out-of-pocket expenses (including counsel fees) incurred by the Administrative Agent in connection with the preparation, execution, delivery, administration, modification, amendment or enforcement (whether through negotiations, legal proceedings or otherwise) of, or legal advice in respect of rights or responsibilities under, this Agreement, any other Credit Document, or any document contemplated by or referred to herein, to the extent that the Administrative Agent is not reimbursed for such expenses by or on behalf of the Borrower and without limiting the obligation of Borrower to do so pursuant to Section 9.04. The undertaking in this Section 8.08 shall survive termination of the Commitments, the payment in full of all Obligations hereunder and the resignation or replacement of the Administrative Agent.

Section 8.09. Administrative Agent in its Individual Capacity . Wells Fargo and its Affiliates may make loans to, accept deposits from, acquire equity interests in and generally engage in any kind of banking, trust, financial advisory, underwriting or other business with the Borrower and its Affiliates as though Wells Fargo were not the Administrative Agent or an Issuing Bank hereunder and without notice to or consent of the Lenders. The Lenders acknowledge that, pursuant to such activities, Wells Fargo or

its Affiliates may receive information regarding the Borrower or its Affiliates (including information that may be subject to confidentiality obligations in favor of Borrower or such Affiliate) and acknowledge that the Administrative Agent shall be under no obligation to provide such information to them. With respect to its Advances, Wells Fargo shall have the same rights and powers under this Agreement as any other Lender and may exercise such rights and powers as though it were not the Administrative Agent or an Issuing Bank, and the terms “Lender” and “Lenders” include Wells Fargo in its individual capacity.

Section 8.10. Successor Administrative Agent and Issuing Bank . The Administrative Agent or any Issuing Bank may resign at any time upon 30 days’ notice to the Lenders with a copy of such notice to the Borrower. If the Administrative Agent or any Issuing Bank resigns under this Agreement, the Majority Lenders shall appoint from among the Lenders a successor administrative agent or issuing bank for the Lenders which successor administrative agent or issuing bank shall be consented to by the Borrower at all times other than during the existence of an Event of Default. If no successor administrative agent or issuing bank is appointed prior to the effective date of the resignation of the Administrative Agent or the applicable Issuing Bank, the Administrative Agent may appoint, after consulting with the Lenders and the Borrower, a successor administrative agent and/or issuing bank from among the Lenders. Upon the acceptance of its appointment as successor administrative agent and/or issuing bank hereunder, such successor administrative agent and/or issuing bank shall succeed to all the rights, powers and duties of the retiring Administrative Agent or Issuing Bank and the term “Administrative Agent” and “Issuing Bank” shall mean such successor administrative agent or issuing bank and the retiring Administrative Agent’s or Issuing Bank’s appointment, powers and duties as Administrative Agent or Issuing Bank shall be terminated. The resigning Issuing Bank shall remain the Issuing Bank with respect to any Letters of Credit outstanding on the effective date of its resignation and the provisions affecting such Issuing Bank with respect to Letters of Credit shall inure to the benefit of the resigning Issuing Bank until the termination of all such Letters of Credit. After any retiring Administrative Agent’s resignation hereunder as Administrative Agent, the provisions of this Article VIII and Sections 9.04 and 9.09 shall inure to its benefit as to any actions taken or omitted to be taken by it while it was Administrative Agent under this Agreement. If no successor administrative agent has accepted appointment as Administrative Agent by the date which is 30 days following a retiring Administrative Agent’s notice of resignation, the retiring Administrative Agent’s resignation shall nevertheless thereupon become effective and the Lenders shall perform all of the duties of the Administrative Agent hereunder until such time, if any, as the Majority Lenders appoint a successor agent as provided for above.

Section 8.11. Syndication Agent; Other Agents; Arrangers . None of the Lenders or other Persons identified on the facing page or signature pages of this Agreement as a “syndication agent,” as a “documentation agent,” any other type of agent (other than the Administrative Agent), “arranger,” or “bookrunner” shall have any right, power, obligation, liability, responsibility or duty under this Agreement other than those applicable to all Lenders as such. Without limiting the foregoing, none of the Lenders so identified shall have or be deemed to have any fiduciary relationship with any Lender.

(i) to file and prove a claim for the whole amount of the principal and interest owing and unpaid in respect of the Advances, Letter of Credit Exposures and all other Obligations that are owing and unpaid and to file such other documents as may be necessary or advisable in order to have the claims of the Lenders, the Issuing Banks and the Administrative Agent (including any claim for the reasonable compensation, expenses, disbursements and advances of the Lenders, the Issuing Banks and the Administrative Agent and their respective agents and counsel and all other amounts due the Lenders, the Issuing Banks and the Administrative Agent under Sections 2.06 and 9 . 04) allowed in such judicial proceeding; and

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

and any custodian, receiver, assignee, trustee, liquidator, sequestrator or other similar official in any such judicial proceeding is hereby authorized by each Lender and Issuing Bank to make such payments to the Administrative Agent and, in the event that the Administrative Agent shall consent to the making of such payments directly to the Lenders and Issuing Banks, to pay to the Administrative Agent any amount due for the reasonable compensation, expenses, disbursements and advances of the Administrative Agent and its agents and counsel, and any other amounts due the Administrative Agent under Sections 2.06 and 9.04.

Nothing contained herein shall be deemed to authorize the Administrative Agent to authorize or consent to or accept or adopt on behalf of any Lender or Issuing Bank any plan of reorganization, arrangement, adjustment or composition affecting the Obligations or the rights of any Lender or to authorize the Administrative Agent to vote in respect of the claim of any Lender in any such proceeding.

Section 8.13. Lender Hedging Agreements To the extent any Affiliate of a Lender (or former Lender or former Affiliate of a Lender) is a party to a Lender Hedging Agreement with the Borrower or any of its Subsidiaries or any Holdco Entity and thereby becomes a beneficiary of the Liens pursuant to any Security Document (if any), such Person shall be deemed to appoint the Administrative Agent its nominee and agent to act for and on behalf of such Person in connection with such Security Documents and to be bound by the terms of this Article VIII, Section 9.01(h) and the last sentence of Section 2.16.

Section 8.15. Lender ERISA Representation . Each Lender as of the Effective Date represents and warrants as of the Effective Date to the Administrative Agent, the Arrangers and their respective Affiliates, and not, for the avoidance of doubt, for the benefit of the Borrower or any other Loan Party, that such Lender is not and will not be (1) an employee benefit plan subject to Title I of ERISA, (2) a plan or account subject to Section 4975 of the Code; (3) an entity deemed to hold “plan assets” of any such plans or accounts for purposes of ERISA or the Code; or (4) a “governmental plan” within the meaning of ERISA.

Section 9.09. Survival of Representations, etc . All representations and warranties contained in this Agreement or made in writing by or on behalf of the Borrower in connection herewith shall survive the execution and delivery of this Agreement and the other Credit Documents, the making of the Advances and any investigation made by or on behalf of the Administrative Agent or any Lender, none of which investigations shall diminish the Administrative Agent’s or any Lender’s right to rely on such representations and warranties. All obligations of the Borrower provided for in Sections 2.10, 2.11, 2.12, 9.04 and 9.07 and all of the obligations of the Lenders in Section 2.09 and 8.08 shall survive any termination of this Agreement and repayment in full of the Obligations.

Section 9.10. Severability . In case one or more provisions of this Agreement or the other Credit Documents shall be invalid, illegal, or unenforceable in any respect under any applicable law, the validity, legality, and enforceability of the remaining provisions contained herein or therein shall not be affected or impaired thereby. Without limiting the foregoing provisions of this Section 9.10, if and to the extent that the enforceability of any provisions in this Agreement relating to Defaulting Lenders shall be limited by applicable bankruptcy laws, as determined in good faith by the Administrative Agent or the Issuing Banks, as applicable, then such provisions shall be deemed to be in effect only to the extent not so limited.

Section 9.11. Business Loans . The Borrower warrants and represents that the Advances evidenced by the Notes are and shall be for business, commercial, investment, or other similar purposes

and not primarily for personal, family, household, or agricultural use, as such terms are used in Chapter One (“ Chapter One ”) of the Texas Finance Code. At all such times, if any, as Chapter One shall establish a Maximum Rate, the Maximum Rate shall be the “indicated rate ceiling” (as such term is defined in Chapter One) from time-to-time in effect.

Section 9.12. Usury Not Intended . It is the intent of the Borrower, the Administrative Agent, the Issuing Banks, and the Lenders in the execution and performance of this Agreement and the other Credit Documents to contract in strict compliance with applicable usury laws, including conflicts of law concepts, governing the Advances of the Lenders including such applicable laws of the State of Texas and the United States of America from time-to-time in effect. In furtherance thereof, the Administrative Agent, the Lenders, and the Borrower stipulate and agree that none of the terms and provisions contained in this Agreement or the other Credit Documents shall ever be construed to create a contract to pay, as consideration for the use, forbearance or detention of money, interest at a rate in excess of the Maximum Rate and that for purposes hereof “interest” shall include the aggregate of all charges which constitute interest under such laws that are contracted for, charged, or received under this Agreement and the other Credit Documents; and in the event that, notwithstanding the foregoing, under any circumstances the aggregate amounts taken, reserved, charged, received, or paid on the Advances, include amounts which by applicable law are deemed interest which would exceed the Maximum Rate, then such excess shall be deemed to be a mistake and the Lender receiving same shall credit the same on the principal of its Notes (or if its Notes shall have been paid in full, refund said excess to the Borrower). In the event that the maturity of the Notes is accelerated by reason of any election of the holder thereof resulting from any Event of Default under this Agreement or otherwise, or in the event of any required or permitted prepayment, then such consideration that constitutes interest may never include more than the Maximum Rate and excess interest, if any, provided for in this Agreement or otherwise shall be canceled automatically as of the date of such acceleration or prepayment and, if theretofore paid, shall be credited on the Notes (or, if the Notes shall have been paid in full, refunded to the Borrower of such interest). The provisions of this Section shall control over all other provisions of this Agreement or the other Credit Documents which may be in apparent conflict herewith. In determining whether or not the interest paid or payable under any specific contingencies exceeds the Maximum Rate, the Borrower, the Administrative Agent, the Issuing Banks, and the Lenders shall to the maximum extent permitted under applicable law amortize, prorate, allocate and spread in equal parts during the period of the full stated term of the Note, all amounts considered to be interest under applicable law at any time contracted for, charged, received or reserved in connection with the Obligations.

foregoing shall not apply to any consequential damages payable to a third person (that is, a Person other than the Borrower, the Administrative Agent, the Issuing Banks, any Lender and each of the foregoing’s respective Affiliates, directors, officers, employees and agents) for which indemnification is sought under this Agreement.

Section 9.21. Commodity Act Keepwell Provisions . The Borrower, to the extent that it is a Qualified ECP Guarantor, hereby guarantees the payment and performance of all Obligations in respect of any Lender Hedging Agreement of each Guarantor and absolutely, unconditionally and irrevocably undertakes to provide such funds or other support as may be needed from time to time by each Guarantor in order for such Guarantor to honor its obligations under the Guaranty with respect to Lender Hedging Agreements (provided, however, that the Borrower, to the extent it is a Qualified ECP Guarantor, shall only be liable under this Section for the maximum amount of such liability that can be hereby incurred (a) without rendering its obligations under this Section, or otherwise under this Agreement or any other Credit Document, as it relates to such Guarantors, voidable under laws relating to fraudulent conveyance or fraudulent transfer, and not for any greater amount and (b) without rendering such Guarantor liable for amounts to creditors, other than to a counterparty to a Lender Hedging Agreement, that such Guarantor would not otherwise have made available to such creditors if this Section 9.21 was not in effect). The obligations of the Borrower, to the extent it is a Qualified ECP Guarantor, under this Section shall remain in full force and effect until all Obligations (other than Unliquidated Obligations) are paid in full to the Lenders, the Administrative Agent and the counterparties to all Lender Hedging Agreements, and all of the Lenders’ Commitments are terminated. The Borrower intends that this Section 9.21 constitute, and this Section 9.21 shall be deemed to constitute, a “keepwell, support, or other agreement” for the benefit of each other Loan Party for all purposes of Section 1a(18)(A)(v)(II) of the Commodity Exchange Act.

Section 9.22. No Fiduciary Duty . Each Lender and their Affiliates (collectively, solely for purposes of this Section 9.22, the “ Lenders ”), may have economic interests that conflict with those of the Loan Parties and their respective Subsidiaries, their equityholders and/or their Affiliates. Each Loan Party, for itself and on behalf of its Subsidiaries, agrees that nothing in this Agreement or the other Credit Documents will be deemed to create an advisory, fiduciary or agency relationship or fiduciary or other implied duty between any Lender, on the one hand, and any Loan Party or its Subsidiaries, their equityholders or their Affiliates, on the other. Each Loan Party, for itself and on behalf of its Subsidiaries, acknowledges and agrees that (i) the transactions contemplated by the Credit Documents (including the exercise of rights and remedies hereunder and thereunder) are arm’s-length commercial transactions between the Lenders, on the one hand, and the Loan Parties and their Subsidiaries, on the other, and (ii) in connection therewith and with the process leading thereto, (x) no Lender has assumed an advisory or

fiduciary responsibility in favor of any Loan Party or its Subsidiaries, their equityholders or their Affiliates with respect to the transactions contemplated hereby (or the exercise of rights or remedies with respect thereto) or the process leading thereto (irrespective of whether any Lender has advised, is currently advising or will advise any Loan Party or its Subsidiaries, their equityholders or their Affiliates on other matters) or any other obligation to any Loan Party or any of its Subsidiaries except the obligations expressly set forth in the Credit Documents and (y) each Lender is acting solely as principal and not as the agent or fiduciary of any Loan Party or any of its Subsidiaries, their officers, equityholders, creditors or any other Person. Each Loan Party, for itself and its Subsidiaries, acknowledges and agrees that it has consulted its own legal and financial advisors to the extent it deemed appropriate and that it is responsible for making its own independent judgment with respect to such transactions and the process leading thereto. Each Loan Party, for itself and its Subsidiaries, agrees that it will not claim that any Lender has rendered advisory services of any nature or respect, or owes a fiduciary or similar duty to such Loan Party or Subsidiary, in connection with such transaction or the process leading thereto.
