any other Loan Document. Anything in the Uniform Customs and Practice to the contrary notwithstanding:

(a) Neither the Borrower nor any beneficiary of any Letter of Credit shall be deemed an agent of any Letter of Credit Issuer.

2.2.8 Subrogation. Subject to the terms of the Intercreditor Agreement, upon any payment by a Letter of Credit Issuer under any Letter of Credit and until the reimbursement of such Letter of Credit Issuer by the Borrower with respect to such payment, the Letter of Credit Issuer shall be entitled to be subrogated to, and to acquire and retain, the rights which the Person to whom such payment is made may have against the Borrower, all for the benefit of the Banks. Subject to the terms of the Intercreditor Agreement, the Borrower will take such action as the Letter of Credit Issuer may reasonably request, including requiring the beneficiary of any Letter of Credit to execute such documents as the Letter of Credit Issuer may reasonably request, to assure and confirm to the Letter of Credit Issuer such subrogation and such rights, including the rights, if any, of the beneficiary to whom such payment is made in accounts receivable, inventory and other properties and assets of the Borrower.

2.2.9 Modification, Consent. If the Borrower requests or consents in writing to any modification or extension of any Letter of Credit, or waives any failure of any draft, certificate or other document to comply with the terms of such Letter of Credit, and if the Letter of Credit Issuer consents thereto, the Letter of Credit Issuer shall be entitled to rely on such request, consent or waiver.

During the period of time in which Revolving Loans may be requested under the Revolving Facility, and subject to the terms and conditions of this Agreement, the Swingline Lender agrees to make certain revolving loans (collectively the “Swingline Loans”) to the Borrower; provided that the aggregate principal amount of Swingline Loans at any time outstanding shall not exceed the Swingline Facility Amount. All Swingline Loans shall be Base Rate Loans evidenced by Borrower’s promissory notes issued to the order of the Swingline Lender (collectively, the “Swingline Notes”), and may be repaid and reborrowed in accordance with the provisions hereof.

2.4 Additional Provisions Relating to Swingline Loans. The Swingline Lender may, at any time, in its sole discretion, by written notice to the Borrower and the Banks, demand repayment of its Swingline Loans by way of a Revolving Loan advance, in which case the Borrower shall be deemed to have requested a Revolving Loan advance comprised solely of Base Rate Loans in the amount of such Swingline Loans; provided, however, that any such demand shall be deemed to have been given one Business Day prior to the Final Maturity Date and on the date of the occurrence of any Event of Default described in Section 9.1 and upon acceleration of the indebtedness hereunder and the exercise of remedies in accordance with the provisions of Section 9.2. Each Swingline Loan shall accrue interest at a variable annual rate equal to the Base Rate plus the Applicable Margin, if any, for Swingline Loans. Each Bank hereby irrevocably agrees to make its Percentage Interest of each such Swingline Loan in the amount, in the manner and on the date specified in the preceding sentence notwithstanding (i) the amount of such borrowing may not comply with the minimum amount for advances of Revolving Loans otherwise required hereunder, (ii) whether any conditions specified in Section 6.2 are then satisfied, (iii) whether a Default or an Event of Default then exists, (iv) the failure of any such request or deemed request for Revolving Loan to be made by the time otherwise required hereunder, (v) whether the date of such borrowing is a date on which Revolving Loans are otherwise permitted to be made hereunder or (vi) any termination of the Commitments relating thereto immediately prior to or contemporaneously with such borrowing. In the event that any Revolving Loan cannot for any reason be made on the date otherwise required above (including as a result of the commencement of a proceeding under the Bankruptcy Code with respect to the Borrower), then each Bank hereby agrees that it shall forthwith purchase (as of the date such borrowing would otherwise have occurred, but adjusted for any payments received from the Borrower on or after such date and prior to such purchase) from the Swingline Lender such Participation Interests in the outstanding Swingline Loans as shall be necessary to cause each such Bank to share in such Swingline Loans ratably based upon its Percentage Interest of the Revolving Committed Amount (determined before giving effect to any termination of the Commitments pursuant to Section 9.2), provided that (A) all interest payable on the Swingline Loans shall be for the account of the Swingline Lender until the date as of which the respective Participation Interest is funded and (B) at the time any purchase of Participation Interests pursuant to this sentence is actually made, the purchasing Bank shall be required to pay to the Swingline Lender, to the extent not paid to the Swingline Lender by the Borrower in accordance herewith, interest on the principal amount of Participation Interests purchased for each day from and including the day upon which such borrowing would otherwise have occurred to but excluding the date of payment for such Participation Interests, at the rate equal to the Federal Funds Rate.

2.6 Nature of Obligations of Banks to Make Extensions of Credit. The Banks’ obligations to extend credit under this Agreement, including without limitation, to refinance the credit facilities previously governed by the Existing Credit Agreement, are several and are not joint or joint and several. If on the date any Loans are to be made, any Bank shall fail to perform its obligations under this Agreement, the aggregate amount of Commitments to make the extensions of credit under this Agreement shall be reduced by the amount of unborrowed Commitments of the Bank so failing to perform and the Percentage Interests shall be appropriately adjusted. Banks that have not failed to perform their obligations to make the extensions of credit contemplated by Section 2.1 may, if any such Bank so desires, assume, in such proportions as such Banks may agree, the obligations of any Bank who has so failed and the Percentage Interests shall be appropriately adjusted. The provisions of this Section 2.6 shall not affect the rights of the Borrower against any Bank failing to perform its obligations hereunder.

2.7 Accordion Feature. In the event that neither (i) a Default nor an Event of Default has occurred and remains uncured hereunder nor (ii) a Default or Event of Default would be caused by or result from the Borrower’s exercise of the provisions of this Section 2.7, the Borrower may request in writing increases (“Increase Requests”) in the Maximum Amount of Revolving Credit above $75,000,000 (but in no event shall Increase Requests cause such Maximum Amount of Revolving Credit to exceed the remainder of (A) $150,000,000 minus (B) the aggregate amount of reductions therein in accordance with Section 2.8), subject to the following terms, provisions, conditions and limitations:

2.7.3 Additional Documentation. Borrower shall execute and deliver to the Administrative Agent such replacement or additional notes, closing opinions and other loan documents and certificates as may be deemed reasonably necessary or appropriate by the Administrative Agent in connection with the consummation of each Increase Request.

(iii) the Borrower shall pay any fees required pursuant to this Section 2.7.

2.8 Reductions in Maximum Amount of Revolving Credit.

ARTICLE III

INTEREST; EURODOLLAR PRICING OPTIONS; FEES

3.1 Interest. Each Loan shall accrue and bear interest at a rate per annum which shall at all times equal its Applicable Rate. Prior to any stated or accelerated maturity of any Loan, the Borrower will, on the last day of each month, commencing July 31, 2006, pay the accrued and unpaid interest on the portion of such Loan which was not subject to a Eurodollar Pricing Option. On the last day of each Eurodollar Interest Period, but in no event less frequently than the last day of each three month period or on any earlier termination of any Eurodollar Pricing Option, the Borrower will pay the accrued and unpaid interest on the portion of such Loan which was subject to the Eurodollar Pricing Option which expired or terminated or had its three month anniversary on such date. On the Final Maturity Date or the earlier accelerated maturity of any Loan, the Borrower will pay all accrued and unpaid interest on such Loan, including any accrued and unpaid interest on any portion of such Loan which is subject to a Eurodollar Pricing Option. Upon the occurrence and during the continuance of an Event of Default, the Banks may require accrued interest to be payable on demand or at regular intervals more frequent than each Payment Date. All payments of interest hereunder shall be made to the Administrative Agent, for the account of each Bank in accordance with such Bank’s Percentage Interest.

3.2 Eurodollar Pricing Options.

3.2.1 Election of Eurodollar Pricing Options. Subject to all of the terms and conditions hereof and so long as no Default exists, the Borrower may from time to time, by irrevocable notice to the Administrative Agent, actually received not less than two (2) Banking Days prior to the commencement of the Eurodollar Interest Period selected in such notice, elect to have such portion of a Loan as the Borrower may specify in such notice accrue and bear interest during the Eurodollar Interest Period so selected at the Applicable Rate computed on the basis of the Eurodollar Rate. No such election shall become effective:

(i) if, prior to the commencement of any such Eurodollar Interest Period, the Administrative Agent determines that (i) the electing or granting of the Eurodollar Pricing Option in question would violate a Bank Legal Requirement, (ii) Eurodollar deposits in an amount comparable to the principal amount of the Loan as to which such Eurodollar Pricing Option has been elected and which have a term corresponding to the proposed Eurodollar Interest Period are not readily available in the inter-bank Eurodollar market, or (iii) by reason of circumstances affecting the inter-bank Eurodollar market, adequate and reasonable methods do not exist for ascertaining the interest rate applicable to such deposits for the proposed Eurodollar Interest Period; or

(ii) if any Bank shall have advised the Administrative Agent, by telephone or otherwise at or prior to noon (Tulsa, Oklahoma time) on the Banking

Day immediately prior to the commencement of such proposed Eurodollar Interest Period (and shall have subsequently confirmed in writing) that, after reasonable efforts to determine the availability of such Eurodollar deposits, such Bank reasonably anticipates that Eurodollar deposits in an amount equal to the Percentage Interest of such Bank in the portion of such Loan as to which such Eurodollar Pricing Option has been elected and which have a term corresponding to the Eurodollar Interest Period in question will not be offered in the Eurodollar market to such Bank at a rate of interest that does not exceed the anticipated Eurodollar Basic Rate.

3.2.2 Notice to Banks and Borrower. The Administrative Agent, will promptly inform each Bank (by telephone or otherwise) of each notice received by it from the Borrower pursuant to Section 3.2.1 and of the Eurodollar Interest Period specified in such notice. Upon determination by the Administrative Agent of the Eurodollar Rate for such Eurodollar Interest Period or in the event such election shall not become effective, the Administrative Agent, will promptly notify the Borrower and each Bank (by telephone or otherwise) of the Eurodollar Rate so determined or why such election did not become effective, as the case may be.

3.2.3 Selection of Eurodollar Interest Periods. Eurodollar Interest Periods shall be selected so that:

(i) the minimum portion of a Loan subject to any Eurodollar Pricing Option shall be $500,000 and in integral multiple of $500,000 in excess thereof;

(ii) no more than a total of ten (10) Eurodollar Pricing Options shall be outstanding at any one time with respect to the Loans;

(iii) no Eurodollar Interest Period with respect to any part of a Loan subject to a Eurodollar Pricing Option shall expire later than its applicable Final Maturity Date.

3.2.4 Additional Interest. If any portion of a Loan subject to a Eurodollar Pricing Option is repaid, or any Eurodollar Pricing Option is terminated for any reason (including acceleration of maturity), on a date which is prior to the last Banking Day of the Eurodollar Interest Period applicable to such Eurodollar Pricing Option, the Borrower will pay to the Administrative Agent, for the account of each Bank in accordance with such Bank’s Percentage Interest, in addition to any amounts of interest otherwise payable hereunder, an amount equal to the present value (calculated in accordance with this Section 3.2.4) of interest for the unexpired portion of such Eurodollar Interest Period on the portion of such Loan so repaid, or as to which a Eurodollar Pricing Option was so terminated, at a per annum rate equal to the excess, if any, of (a) the rate applicable to such Eurodollar Pricing Option minus, (b) the lowest rate of interest obtainable by the Administrative Agent upon the purchase of debt securities customarily issued by the Treasury of the United States of America which have a maturity date approximating the last Banking Day of such Eurodollar Interest Period. The present value of such

additional interest shall be calculated by discounting the amount of such interest for each day in the unexpired portion of such Eurodollar Interest Period from such day to the date of such repayment or termination at a per annum interest rate equal to the interest rate determined pursuant to clause (b) of the preceding sentence, and by adding all such amounts for all such days during such period. The determination by the Administrative Agent of such amount of interest shall, in the absence of manifest error, be conclusive. For purposes of this Section 3.2.4, if any portion of a Loan which was to have been subject to a Eurodollar Pricing Option is not outstanding on the first day of the Eurodollar Interest Period applicable to such Eurodollar Pricing Option other than for reasons described in Section 3.2.1, the Borrower shall be deemed to have terminated such Eurodollar Pricing Option.

3.2.5 Violation of Bank Legal Requirements. If any Bank Legal Requirement shall prevent any Bank from funding or maintaining through the purchase of deposits in the interbank Eurodollar market any portion of a Loan subject to a Eurodollar Pricing Option or otherwise from giving effect to such Bank’s obligations as contemplated by Section 3.2, (a) the Administrative Agent, may by notice to the Borrower terminate all of the affected Eurodollar Pricing Options, (b) the portion of such Loan subject to such terminated Eurodollar Pricing Options shall immediately bear interest thereafter at the Applicable Rate computed on the basis of the Base Rate and (c) the Borrower shall make any payment required by Section 3.2.4.

3.2.6 Funding Procedure. The Banks may fund any portion of a Loan subject to a Eurodollar Pricing Option out of any funds available to the Banks. Regardless of the source of the funds actually used by any of the Banks to fund any portion of such Loan subject to a Eurodollar Pricing Option, however, all amounts payable hereunder, including the interest rate applicable to any such portion of the Loan and the amounts payable under Sections 3.2.4, 3.5, 3.6, 3.7 and 3.8, shall be computed as if each Bank had actually funded such Bank’s Percentage Interest in such portion of such Loan through the purchase of deposits in such amount of the type by which the Eurodollar Basic Rate was determined with a maturity the same as the applicable Eurodollar Interest Period relating thereto and through the transfer of such deposits from an office of the Bank having the same location as the applicable Eurodollar Office to one of such Bank’s offices in the United States of America.

3.3 Commitment Fees. In consideration of the Banks’ commitments to make the extension of credit provided for in Section 2.1 while such commitments are outstanding, the Borrower will pay to the Administrative Agent, for the account of the Banks in accordance with the Banks’ respective Percentage Interests, within five (5) Banking Days following the end of each fiscal quarter of the Borrower and on the Final Maturity Date with respect to the Revolving Loan, an amount equal to interest computed at the rate per annum equal to the Applicable Commitment Fee Percentage multiplied by the amount by which (a) the average daily Maximum Amount of Revolving Credit (taking into account any increases thereof above $75,000,000 pursuant to the provisions of Section 2.7) during the Margin Period or portion thereof ending on the last day of such fiscal quarter or Final Maturity Date exceeded (b) the average daily Revolving Loan during such Margin Period or portion thereof. For the purposes of computing

such fee, outstanding Letters of Credit shall be deemed to be part of the Revolving Loan and usage of the Revolving Credit Facility; however, outstanding Swingline Loans shall be considered usage of the Revolving Facility committed amount of BOk only.

3.4 Letter of Credit Fees. The Borrower will pay to the Administrative Agent, for the account of each of the Banks (including any Letter of Credit Issuer), in accordance with the Banks’ respective Percentage Interests, on the last day of each Margin Period, a Letter of Credit fee equal to the Applicable Margin for Eurodollar Loans in effect for such Margin Period on the average daily Letter of Credit Exposure during such Margin Period. An additional fee equal to 1/8% per annum on the Letter of Credit Exposure shall be paid solely to the Letter of Credit Issuer. The Borrower also will pay to each Letter of Credit Issuer customary service charges and expenses for its services in connection with the Letters of Credit issued by it at the times and in the amounts from time to time in effect in accordance with its general rate structure, including fees and expenses relating to issuance, amendment, negotiation, cancellation and similar operations.

3.5 Reserve Requirements. If any Bank Legal Requirement shall (a) impose, modify, increase or deem applicable any insurance assessment, reserve, special deposit or similar requirement against any Funding Liability or the Letters of Credit, (b) impose, modify, increase or deem applicable any other requirement or condition with respect to any Funding Liability or the Letters of Credit, or (c) change the basis of taxation of Funding Liabilities or payments in respect of any Letter of Credit (other than changes in the rate of taxes measured by the overall net income of such Bank) and the effect of any of the foregoing shall be to increase the cost to any Bank of issuing, making, funding or maintaining its respective Percentage Interest in any portion of a Loan subject to a Eurodollar Pricing Option or any Letter of Credit, to reduce the amounts received or receivable by such Bank under this Agreement or to require such Bank to make any payment or forego any amounts otherwise payable to such Bank under this Agreement, then, within 15 days after the receipt by the Borrower of a certificate from such Bank setting forth why it is claiming compensation under this Section 3.5 and computations (in reasonable detail) of the amount thereof, the Borrower shall pay to the Administrative Agent, for the account of such Bank such additional amounts as are specified by such Bank in such certificate as sufficient to compensate such Bank for such increased cost or such reduction, together with interest at the Overdue Reimbursement Rate on such amount from the 15th day after receipt of such certificate until payment in full thereof; provided, however, that the foregoing provisions shall not apply to any Tax or to any reserves which are included in computing the Eurodollar Reserve Rate. The determination by such Bank of the amount of such costs shall, in the absence of manifest error, be conclusive.

3.6 Taxes. All payments of the Credit Obligations shall be made without set-off or counterclaim and free and clear of any deductions, including deductions for Taxes, unless the Borrower is required by law to make such deductions. If (a) any Bank shall be subject to any Tax with respect to any payment of the Credit Obligations or its obligations hereunder or (b) the Borrower shall be required to withhold or deduct any Tax on any payment on the Credit Obligations, within 15 days after the receipt by the Borrower of a certificate from such Bank setting forth why it is claiming compensation under this Section 3.6 and computations (in reasonable detail) of the amount thereof, the Borrower shall pay to the Administrative Agent, for

such Bank’s account such additional amount as is necessary to enable such Bank to receive the amount of Tax so imposed on the Bank’s obligations hereunder or the full amount of all payments which it would have received on the Credit Obligations (including amounts required to be paid under Sections 3.5, 3.7, 3.8 and this Section 3.6) in the absence of such Tax, as the case may be, together with interest at the Overdue Reimbursement Rate on such amount from the 15th day after receipt of such certificate until payment in full thereof. Whenever Taxes must be withheld by the Borrower with respect to any payments of the Credit Obligations, the Borrower shall promptly furnish to the Administrative Agent for the account of the applicable Bank official receipts (to the extent that the relevant governmental authority delivers such receipts) evidencing payment of any such Taxes so withheld. If the Borrower fails to pay any such Taxes when due or fails to remit to the Administrative Agent, for the account of the applicable Bank the required receipts evidencing payment of any such Taxes so withheld or deducted, the Borrower shall indemnify the affected Bank for any incremental Taxes and interest or penalties that may become payable by such Bank as a result of any such failure. The determination by such Bank of the amount of such Tax and the basis therefor shall, in the absence of manifest error, be conclusive. The Borrower shall be entitled to replace any such Bank in accordance with Section 11.3.

3.7 Capital Adequacy. If any Bank shall determine that compliance by such Bank with any Bank Legal Requirement regarding capital adequacy of banks or bank holding companies has or would have the effect of reducing the rate of return on the capital of such Bank and its Affiliates as a consequence of such Bank’s commitment to make the extensions of credit contemplated hereby, or such Bank’s maintenance of the extensions of credit contemplated hereby, to a level below that which such Bank could have achieved but for such compliance (taking into consideration the policies of such Bank and its Affiliates with respect to capital adequacy immediately before such compliance and assuming that the capital of such Bank and its Affiliates was fully utilized prior to such compliance) by an amount deemed by such Bank to be material, then, within 15 days after the receipt by the Borrower of a certificate from such Bank setting forth why it is claiming compensation under this Section 3.7 and computations (in reasonable detail) of the amount thereof, the Borrower shall pay to the Administrative Agent, for the account of such Bank such additional amounts as shall be sufficient to compensate such Bank for such reduced return, together with interest at the Overdue Reimbursement Rate on each such amount from the 15th day after receipt of such certificate until payment in full thereof. The determination by such Bank of the amount to be paid to it and the basis for computation thereof shall, in the absence of manifest error, be conclusive. In determining such amount, such Bank may use any reasonable averaging, allocation and attribution methods. The Borrower shall be entitled to replace any such Bank in accordance with Section 11.3.

3.8 Regulatory Changes. If any Bank shall determine that (a) any change in any Bank Legal Requirement (including any new Bank Legal Requirement) after the date hereof shall directly or indirectly (i) reduce the amount of any sum received or receivable by such Bank with respect to a Loan or the Letters of Credit or the return to be earned by such Bank on such Loan or the Letters of Credit, (ii) impose a cost on such Bank or any Affiliate of such Bank that is attributable to the making or maintaining of, or such Bank’s commitment to make, its portion of such Loan or the Letters of Credit, or (iii) require such Bank or any Affiliate of such Bank to make any payment on, or calculated by reference to, the gross amount of any amount received by such Bank under any Credit Document, and (b) such reduction, increased cost or payment shall

not be fully compensated for by an adjustment in the Applicable Rate or the Letter of Credit fees, then, within 15 days after the receipt by the Borrower of a certificate from such Bank setting forth why it is claiming compensation under this Section 3.8 and computations (in reasonable detail) of the amount thereof, the Borrower shall pay to such Bank such additional amounts as such Bank determines will, together with any adjustment in the Applicable Rate, fully compensate for such reduction, increased cost or payment, together with interest on such amount from the 15th day after receipt of such certificate until payment in full thereof at the Overdue Reimbursement Rate. The determination by such Bank of the amount to be paid to it and the basis for computation thereof hereunder shall, in the absence of manifest error, be conclusive. In determining such amount, such Bank may use any reasonable averaging and attribution methods.

3.9 Computations of Interest and Fees. For purposes of this Agreement, interest chargeable with respect to the Eurodollar Rate, commitment fees and Letter of Credit fees (and any other amount expressed fees) shall be computed on the basis of a 360-day year for actual days elapsed. All calculations under the Loan Documents of interest chargeable with respect to the Base Rate shall be made on the basis of actual days elapsed (including the first day but excluding the last) and a year of 365 or 366 days, as appropriate. If any payment required by this Agreement becomes due on any day that is not a Banking Day, such payment shall, except as otherwise provided in the Eurodollar Interest Period, be made on the next succeeding Banking Day. If the due date for any payment of principal is extended as a result of the immediately preceding sentence, interest shall be payable for the time during which payment is extended at the Applicable Rate, and any letter of credit fees payable pursuant to Section 3.4 shall be payable for the full number of days such applicable Letter of Credit is outstanding.

3.10 Loan Fees. Concurrent with the Closing Date and, as applicable with any closing of the establishment of any Increase Request effected pursuant to Section 2.7 resulting in an increase in the Maximum Amount of Revolving Credit, the Borrower shall pay to each Bank in immediately available funds a non-refundable and fully earned loan facility fee in an amount equal to 0.30% (30 basis points) of the aggregate amount of each such Bank’s Commitments issued pursuant to this Agreement.

3.11 Administrative Agent and Syndication Agent Fees. The Borrower shall pay to each of the Administrative Agent and the Syndication Agent, for their own respective accounts, an Administrative Agent Fee (to the Administrative Agent) and a Syndication Agent Fee (to the Syndication Agent) as set forth in separate fee agency letters between the Borrower and the Administrative Agent and the Syndication Agent, respectively.

ARTICLE IV

PAYMENT

4.1 Payment at Maturity. On the Final Maturity Date with respect to each tranche or any accelerated maturity of such Loan, the Borrower will pay to the Administrative Agent, for the account of the Banks an amount equal to the remaining aggregate principal amount of such Tranche then outstanding, together with all accrued and unpaid interest thereon and all other Credit Obligations then outstanding.

4.2 Contingent Required Prepayments. If at any time the sum of the Revolving Loan plus the Letter of Credit Exposure exceeds the limit set forth in Section 2.1.2, the Borrower shall within three Banking Days pay the amount of such excess to the Administrative Agent, for the account of the Banks.

(i) If at any time the Borrower or any of its Subsidiaries disposes of assets or issues or sells Capital Stock of any Subsidiary with the result that there are Excess Sale Proceeds, and the Borrower does not apply such Excess Sale Proceeds in the manner described in Section 7B.7(iii)(c)(ii)(x), the Borrower will prepay (at the price of the principal amount prepaid plus accrued interest thereon and any amount owing with respect thereto under Section 3.2.4 and upon notice as provided in Section 4.2.2) a principal amount of the outstanding Revolving Loan equal to the Allocable Proceeds.

(ii) In the event of any damage to, or destruction, condemnation or other taking of, all or any portion of the properties or assets of the Borrower or any of its Subsidiaries, to the extent that the Borrower or any such Subsidiary receives insurance or condemnation proceeds with the result that Unutilized Taking Proceeds exceed $2,500,000 in respect of any fiscal year (such excess amount being herein called “Excess Taking Proceeds”), the Borrower will prepay (at the price of the principal amount prepaid plus accrued interest thereon and any amount owing with respect thereto under Section 3.2.4 and upon notice as provided in Section 4.2.2) a principal amount of the outstanding Revolving Loan equal to the Allocable Proceeds.

(iii) (a) If at any time any Responsible Officer has knowledge of the occurrence of any Control Event, the Borrower will give notice as provided in Section 4.2.2 of such Control Event to the Administrative Agent. Upon the occurrence of a Control Event, the Borrower will not take any voluntary action that consummates or finalizes the Control Event resulting from such Control Event unless contemporaneously with such action, the Borrower prepays all principal outstanding on the Revolving Loan in accordance with this Section 4.2.1(iii) and upon notice as provided in Section 4.2.2 at the price of the principal amount thereof plus accrued interest thereon and any amount owing with respect thereto under Section 3.2.4.

(b) The obligation of the Borrower to prepay the Revolving Loan pursuant to the offer required by paragraph (a) of this clause (iii) and accepted in accordance with Section 4.2.2 is subject to the consummation of the Control Event in respect of which any such offer and acceptance shall have been made. In the event that such Control Event does not occur on or before the proposed prepayment date in respect thereof, the prepayment shall be deferred until and shall be made on the date on which such Control Event occurs. The Borrower shall keep the Administrative Agent reasonably and timely informed of (i) any such deferral of the date of prepayment, (ii) the date on which such Control Event and the prepayment are expected to occur, and (iii) any determination by the Borrower that efforts to effect such resulting Control Event have ceased or been abandoned (in which case the Borrower shall have no further obligation hereunder to prepay the Revolving Loan in respect of such Control Event).

4.2.2 Prepayment Procedure for Contingent Prepayments.

(i) If at any time there are unapplied Excess Proceeds, and the Borrower is required to prepay the Notes with such Excess Proceeds pursuant to clause (i) or (ii) of Section 4.2.1, the Borrower will give written notice as provided in Section 12.1 (which shall be in the form of an Officers’ Certificate) to the Banks not later than twelve months after the date of the applicable Asset Sale or the end of the twelve month period following receipt of the applicable Unutilized Taking Proceeds, as the case may be, and (a) setting forth in reasonable detail all calculations required to determine the amount of Excess Proceeds, (b) setting forth the aggregate amount of the Allocable Proceeds and the amount of the Allocable Proceeds which is allocable to each Note, determined by applying the Allocable Proceeds pro rata among all Notes outstanding on the date such prepayment is to be made according to the aggregate then unpaid amounts of the Revolving Notes, and in reasonable detail the calculations used in determining such amounts, and (c) stating that the Borrower will prepay on the date specified in such notice, which shall not be less than 25 nor more than 45 days after the date of such notice, a principal amount of each outstanding Revolving Note equal to the amount of Allocable Proceeds allocated to such Revolving Note as described in clause (b) above.

(ii) If at any time the Borrower is required to prepay the Notes following the occurrence of a Control Event, the Borrower will give written notice as provided in Section 12.1 (which shall be in the form of an Officer’s Certificate) to the Banks not later than five Business Days following such Control Event, (a) setting forth in reasonable detail the facts and circumstances underlying such Control Event known to it, and (b) stating that the Borrower will prepay on the date the Control Event occurs.

4.3 Scheduled Required Payments. Borrower shall, on the Final Maturity Date, pay all outstanding principal of the Revolving Loan.

4.4 Voluntary Prepayments. In addition to the prepayments required by Sections 4.2 and 4.3, the Borrower may from time to time prepay all or any portion of the Loans (in a minimum amount of $100,000 and an integral multiple of $100,000), without premium or penalty of any type (except as provided in Section 3.2.4 with respect to the early termination of Eurodollar Pricing Options) and further provided that Swingline Loans may be prepaid in any amount. The Borrower shall give the Administrative Agent at least one Banking Day prior notice of its intention to prepay, specifying the date of payment, the total amount of the Loans to be paid on such date and the amount of interest to be paid with such prepayment.

4.5 Letters of Credit. If at the time of any Event of Default or on the stated or any accelerated maturity of the Credit Obligations the Banks shall be obligated in respect of a Letter of Credit or a draft accepted under a Letter of Credit, the Borrower immediately will either:

(a) prepay such obligation by depositing with the Administrative Agent, an amount of cash sufficient to cash-collateralize such Letter of Credit Exposure, or

(b) deliver to the Administrative Agent, a standby letter of credit (designating such Administrative Agent as beneficiary and issued by a bank and on terms reasonably acceptable to such Administrative Agent),

in each case in an amount equal to the portion of the then Letter of Credit Exposure. Any such cash so deposited and the cash proceeds of any draw under any standby letter of credit so furnished, including any interest thereon, shall be returned by such Administrative Agent to the Borrower only when, and to the extent that, the amount of such cash held by such Administrative Agent exceeds the Letter of Credit Exposure at a time when no Default exists; provided, however, that if an Event of Default occurs and the Credit Obligations become or are declared immediately due and payable, Administrative Agent may apply such cash, including any interest thereon, to the payment of any of the Credit Obligations as provided in the Intercreditor Agreement.

4.6 Reborrowing Application of Payments.

4.6.1 Reborrowing. The amounts of the Revolving Loan prepaid pursuant to Section 4.2.1, 4.3.2 or 4.4 may be reborrowed from time to time in accordance with Section 2.1 until the Final Maturity Date and subject to the limits set forth therein.

4.6.2 Payment with Accrued Interest. Upon all prepayments of a Loan, the Borrower shall pay to the Administrative Agent the principal amount to be prepaid, together with unpaid interest in respect thereof accrued to the date of prepayment and any amount owing with respect thereto under Section 3.2.4. Notice of prepayment having

been given in accordance with Section 4.4, and whether or not notice is given of prepayments pursuant to Sections 4.2 and 4.3, the amount specified to be prepaid shall become due and payable on the date specified for prepayment.

4.6.3 Payments for Banks. All payments of principal hereunder shall be made to the Administrative Agent, for the account of the Banks in accordance with the Banks’ respective Percentage Interests.

The Banks hereby authorize the Administrative Agent to execute and deliver such supplements, amendments or modifications to the Intercreditor Agreement to the Collateral Agent. The Borrower confirms that any setoffs shared under the terms of the Intercreditor Agreement (including without limitation Section 13(c) thereof) with the Note Purchasers of the Private Placement Notes or the holders of any Additional Parity Debt, to the extent of the portions so shared, will not be deemed to pay down the Loan evidenced by the Notes.

(xiv) any of the Security Documents shall at any time, for any reason cease to be in full force and effect or shall fail to constitute a valid, perfected first priority Lien with respect to the Collateral subject to Liens permitted by the Security Agreement or shall be declared to be null and void in whole or in any material respect (i.e., relating to the validity or priority of the Liens created by the Security Documents or the remedies available thereunder) by the judgment of any court or other Governmental Authority having jurisdiction in respect thereof, or if the validity or the enforceability of any of the Security Documents shall be contested by or on behalf of the Borrower, or the Borrower shall renounce any of the Security Documents, or deny that it is bound by the terms of any of the Security Documents; or

(xv) any of the events described in clauses (a), (b), (c) or (d) shall occur: (a) the General Partner shall be engaged in any business or activities other than those permitted by the Partnership Agreement as in effect from time to time and in accordance with Section 7B.8, or (b) ETPGP ceases to be the sole general partner of the Borrower or the Master Partnership, or (c) the Specified Entities shall own, directly or indirectly through Wholly-Owned Subsidiaries, in the aggregate less than 51% of the Capital Stock of the General Partner; or (d) either Designated Current Manager shall, at any time during the Lock-up Period applicable to such Designated Current Manager, own, directly or indirectly, less than 50% of the Common Units of the Master Partnership owned, directly or indirectly, by such Designated Current Manager immediately after giving effect to the Proposed Reorganization; or

(xvi) an ERISA Event shall have occurred that, when taken together with all other such ERISA Events that have occurred, could reasonably be expected to result in liability of the Borrower and its ERISA Affiliates in an aggregate amount exceeding $2,000,000; or

(xvii) an event of default under any of the Security Documents has occurred and is continuing.

9.2 Remedies. Upon the occurrence of any Event of Default referred to in (viii), (ix) or (x) of this Section 9.1 the Commitments shall immediately terminate and the Notes and all other Credit Obligations shall be immediately due and payable, without further notice of any kind. Upon the occurrence of any other Event of Default, and without prejudice to any right or remedy of the Banks under this Agreement or the Loan Documents or under applicable Legal Requirements, the Banks may (i) declare the Commitments terminated or (ii) declare the Commitments terminated and declare the Notes and the other Credit Obligations, or any part thereof, to be forthwith due and payable, whereupon the Notes and the other Credit Obligations, or such portion as is designated by the Banks, shall forthwith become due and payable, without presentment, demand, notice or protest of any kind, all of which are hereby expressly waived by the Borrower and the maturity of all of the Loans and Credit Obligations shall be accelerated. No delay or omission on the part of the Banks in exercising any power or right hereunder or under the Notes, the Loan Documents or under applicable law shall impair such right or power or be construed to be a waiver of any default or any acquiescence therein, nor shall any single or partial exercise by the Banks of any such power or right preclude other or further exercise thereof or the exercise of any other such power or right by the Banks. In the event that all or part of the Credit Obligations becomes or is declared to be forthwith due and payable as herein provided, the Banks shall have the right to set off the amount of all such Credit Obligations against all property of the Borrower in any of the Banks’ possession at or subsequent to such Event of Default, regardless of the capacity in which the Banks possess such property, including but not limited to any balance or share of any deposit, collection or agency account. After termination of the Commitments and acceleration of the maturity of the Loans and Credit Obligations hereunder, all proceeds and amounts received by the Banks shall be shared ratably among the Lenders as set forth in Section 9.4. At any time after the occurrence of any Event of Default, the Banks may, at their option, cause an audit of any and/or all of the books, records and documents of the Borrower to be made by auditors satisfactory to the Banks at the expense of the Borrower. The Banks also shall have, and may exercise, each and every right and remedy granted to them under the terms of the Security Documents and the other Loan Documents.

9.3 Other Remedies. If any Event of Default or Default shall occur and be continuing, the Agent on behalf of the Banks may proceed to protect and enforce its rights under this Agreement and such Note by exercising such remedies as are available to such holder in respect thereof under applicable law, either by suit in equity or by action at law, or both, whether for specific performance of any covenant or other agreement contained in this Agreement or in aid of the exercise of any power granted in this Agreement. No remedy conferred in this Agreement upon the holder of any Note is intended to be exclusive of any other remedy, and each and every such remedy shall be cumulative and shall be in addition to every other remedy conferred herein or now or hereafter existing at law or in equity or by statute or otherwise.

9.4 Allocation of Payments After Event of Default. Notwithstanding any other provisions of this Agreement to the contrary, after the occurrence and during the continuance of an Event of Default, all amounts collected or received on or in respect of the Obligations (or other amounts owing under the Loan Documents in connection therewith) shall be paid over or delivered as follows:

FIRST, to the payment of all reasonable out-of-pocket costs and expenses (including reasonable attorneys’ fees) of the Administrative Agent in connection with enforcing the rights and remedies of the Banks under the Loan Documents and any protective advances made with respect thereto;

SECOND, to payment of any fees owed to the Administrative Agent hereunder;

THIRD, to the payment of all reasonable out-of-pocket costs and expenses (including reasonable attorneys’ fees) of each of the Banks hereunder in connection with enforcing its rights under the Loan Documents or otherwise with respect to the Credit Obligations owing to such Banks;

FOURTH, to the payment of all accrued interest and fees on or in respect of the Credit Obligations;

FIFTH, to the payment of the outstanding principal amount of the Credit Obligations (including the payment or cash collateralization of the outstanding Letter of Credit Exposure);

SIXTH, to all other Credit Obligations hereunder and other obligations which shall have become due and payable under the Loan Documents otherwise and not repaid pursuant to clauses “FIRST” through “FIFTH” above; and

SEVENTH, to the payment of the surplus, if any, to the Borrower or such other Persons as may be lawfully entitled to receive such surplus.

In carrying out the foregoing, (i) amounts received shall be applied in the order provided until exhausted prior to application to the next succeeding category; and (ii) except as otherwise provided, the Banks shall receive amounts ratably in accordance with their respective pro rata share (based on the proportion that the then outstanding Obligations held by such Banks bears to the aggregate amount of Obligations then outstanding) of amounts available to be applied pursuant to clauses “THIRD,” “FOURTH,” “FIFTH” and “SIXTH”; and (iii) to the extent that any amounts available for distribution pursuant to clause “FIFTH” above are attributable to the issued but undrawn amount of outstanding Letters of Credit, such amounts shall be held by the Administrative Agent in a cash collateral account and applied (A) first, to reimburse the Issuing Lender for any drawings under such Letters of Credit and (B) then, following the expiration of all Letters of Credit, to all other obligations of the types described in clauses “FOURTH” and “FIFTH” above in the manner provided in this Section 9.4

ARTICLE X

LOAN OPERATIONS

10.1 Interests in Loans/Commitments. The percentage interest of each Bank in the Loans and Letters of Credit, and the Commitments, shall be computed based on the maximum principal amount for each Bank as set forth below (the “Lenders Schedule”):


Bank	Maximum Revolving Loan Commitments		Percentage Interest
BOk	$	23,750,000	31.67	%
JPMorgan	$	23,750,000	31.67	%
Fifth Third	$	15,000,000	20.00	%
US Bank	$	12,500,000	16.66	%
TOTAL	$	75,000,000	100.000	%

The Lenders Schedule percentage interests, as from time to time in effect and reflected in the Register, are referred to as the “Percentage Interests” with respect to all or any portion of the Loans and Letters of Credit, and the Commitments.

10.2 Administrative Agent’s Authority to Act. Each of the Banks appoints and authorizes BOk to act for the Banks as Administrative Agent in connection with the transactions contemplated by this Agreement and the other Loan Documents on the terms set forth herein. In acting hereunder, such Administrative Agent is acting for the account of BOk to the extent of its Percentage Interest and for the account of each other Bank to the extent of such Bank’s Percentage Interest, and all action in connection with the enforcement of, or the exercise of any remedies (other than the Banks’ rights of set-off as provided herein or in any other Loan Document) in respect of the Loans and the Indebtedness shall be taken by such Administrative Agent.

10.3 Borrower to Pay Administrative Agent. The Borrower shall be fully protected in making all payments in respect of the Notes evidencing the Credit Obligations to the Administrative Agent, in relying upon consents, modifications and amendments executed by such Administrative Agent purportedly on the Banks’ behalf, and in dealing with such Administrative Agent as herein provided. Upon three (3) Business Days notice, such Administrative Agent may charge the accounts of the Borrower, on the dates when the amounts thereof become due and payable, with the amounts of the principal of and interest on the Loans, including any amounts paid by such Administrative Agent to third parties under Letters of Credit or drafts presented thereunder, commitment fees, Letter of Credit issuance fees and processing/application fees pertaining thereto and all other fees and amounts owing under any Loan Document.

10.4 Bank Operations for Advances, Letters of Credit.

10.4.1 Advances. On the funding date for each Loan, each Bank shall advance to the Administrative Agent in immediately available funds such Bank’s Percentage Interest in the portion of a Loan advanced on such funding date prior to 12:00 noon (Tulsa, Oklahoma time). If such funds are not received at such time, but all applicable conditions set forth in Article VI have been satisfied, each Bank authorizes and requests such Administrative Agent to advance for the Bank’s account, pursuant to the terms hereof, the Bank’s respective Percentage Interest in such portion of such Loan and agrees to reimburse such Administrative Agent in immediately available funds for the amount thereof prior to 3:00 p.m. (Tulsa, Oklahoma time) on the day any portion of such Loan is advanced hereunder; provided, however, that such Administrative Agent is not authorized to make any such advance for the account of any Bank who has previously notified the Administrative Agent in writing that such Bank will not be performing its obligations to make further advances hereunder; and provided, further, that such Administrative Agent shall be under no obligation to make any such advance.

10.4.2 Letters of Credit. Each of the Banks authorizes and requests each Letter of Credit Issuer to issue the Letters of Credit provided for in Section 2.2 and agrees to purchase a participation in each of such Letters of Credit in an amount equal to its Percentage Interest in the amount of each such Letter of Credit. Promptly upon the request of any Letter of Credit Issuer, each Bank shall reimburse such Letter of Credit Issuer in immediately available funds for such Bank’s Percentage Interest in the amount of all obligations to third parties incurred by the Letter of Credit Issuer in respect of each Letter of Credit and each draft accepted under a Letter of Credit to the extent not timely reimbursed by the Borrower. Each Letter of Credit Issuer will notify each Bank (and the Administrative Agent if the Administrative Agent is not the Letter of Credit Issuer) of the issuance of each Letter of Credit, the amount and date of payment of any draft drawn or accepted under a Letter of Credit and whether in connection with the payment of any such draft the amount thereof was added to the Revolving Loan or was reimbursed by the Borrower.

10.4.3 Administrative Agent to Allocate Payments. All payments of principal and interest in respect of the extensions of credit made pursuant to this Agreement, reimbursement of amounts paid by each Letter of Credit Issuer to third parties under Letters of Credit or drafts presented thereunder, commitment fees, Letter of Credit issuance fees and other fees under this Agreement (except for the standard Letter of Credit application/processing fees of any Letter of Credit Issuer and any fees due to the Administrative Agent), which shall not be shared by the Banks shall, as a matter of convenience, be made by the Borrower to the applicable Letter of Credit Issuer or the applicable Agent, as the case may be. The share of each Bank shall be credited to such Bank by the Administrative Agent, in immediately available funds in such manner that the principal amount of the Loans constituting Credit Obligations to be paid shall be paid proportionately in accordance with the Banks’ respective Percentage Interests in such Loans, except as otherwise provided in this Agreement. Under no circumstances shall any Bank be required to produce or present its Notes as evidence of its interests in the Loans constituting Credit Obligations in any action or proceeding relating to the Loans constituting Credit Obligations.

10.4.4 Delinquent Banks; Nonperforming Banks. In the event that any Bank fails to reimburse the Administrative Agent, pursuant to Section 10.4.1 for the Percentage Interest of such Bank (a “Delinquent Bank”) in any credit advanced by such Administrative Agent pursuant hereto, overdue amounts (the “Delinquent Payment”) due from the Delinquent Bank to such Administrative Agent shall bear interest, payable by the Delinquent Bank on demand, at a per annum rate equal to (a) the Federal Funds Rate for the first three days overdue and (b) the sum of two percentage points (2%) plus the Federal Funds Rate for any longer period. Such interest shall be payable to such Administrative Agent for its own account for the period commencing on the date of the Delinquent Payment and ending on the date the Delinquent Bank reimburses such Administrative Agent on account of the Delinquent Payment (to the extent not paid by the Borrower as provided below) and the accrued interest thereon (the “Delinquency Period”), whether pursuant to the assignments referred to below or otherwise. Upon notice by such Administrative Agent, the Borrower will pay to such Administrative Agent the principal (but not the interest) portion of the Delinquent Payment. During the Delinquency Period, in order to make reimbursements for the Delinquent Payment and accrued interest thereon, the Delinquent Bank shall be deemed to have assigned to such Administrative Agent all interest, commitment fees and other payments made by the Borrower under Articles II, III and IV hereof that would have thereafter otherwise been payable under the Loan Documents to the Delinquent Bank. During any other period in which any Bank is not performing its obligations to extend credit under Article II hereof (a “Nonperforming Bank”), the Nonperforming Bank shall be deemed to have assigned to each Bank that is not a Nonperforming Bank (a “Performing Bank”) such Performing Banks’ respective Percentage Interest in all principal and other payments made by the Borrower that would have thereafter otherwise been payable thereunder to the Nonperforming Bank. Such Administrative Agent shall credit a portion of such payments to each Performing Bank in an amount equal to the Percentage Interest of such Performing Bank in an amount equal to the Percentage Interest of such Performing Bank divided by one minus the Percentage Interest of the Nonperforming Bank until the respective portions of the Loans owed to all the Banks are the same as the Percentage Interests of the Banks immediately prior to the failure of the Nonperforming Bank to perform its obligations under Article II hereof. The foregoing provisions shall be in addition to any other remedies the Administrative Agent, the Performing Banks or the Borrower may have under law or equity against the Delinquent Bank as a result of the Delinquent Payment or against the Nonperforming Bank as a result of its failure to perform its obligations under Article II hereof.

10.5 Sharing of Payments. To the extent permitted by applicable Bank Legal Requirements and subject to the provisions of the Intercreditor Agreement, each Bank agrees that (i) if by exercising any right of set-off or counterclaim or otherwise, it shall receive payment of (a) a proportion of the aggregate amount due with respect to its Percentage Interest in the Loans and Letter of Credit Exposure which is greater than (b) the proportion received by any other Bank in respect of the aggregate amount due with respect to such other Bank’s Percentage

Interest in the Loans and Letter of Credit Exposure and (ii) if such inequality shall continue for more than 10 days, the Bank receiving such proportionately greater payment shall purchase participations in the Percentage Interests in the Loans and Letter of Credit Exposure held by the other Banks, and such other adjustments shall be made from time to time (including rescission of such purchases of participations in the event the unequal payment originally received is recovered from such Bank through bankruptcy proceedings or otherwise), as may be required so that all such payments of principal and interest with respect to the Loans and Letter of Credit Exposure held by the Banks shall be shared by the Banks pro rata in accordance with their respective Percentage Interests; provided, however, that this Section 10.5 shall not impair the right of any Bank to exercise any right of set-off or counterclaim it may have and to apply the amount subject to such exercise to the payment of Indebtedness of Borrower other than Borrower’s Indebtedness with respect to the Loans and Letter of Credit Exposure. Each Bank that grants a participation in the Loans and Commitments to a Credit Participant shall require as a condition to the granting of such participation that such Participant agree to share payments received in respect of the Indebtedness as provided in this Section 10.5. The provisions of this Section 10.5 are for the sole and exclusive benefit of the Banks and no failure of any Bank to comply with the terms hereof shall be available to either Borrower as a defense to the payment of the Loans.

10.6 Amendments, Consents, Waivers. Except as otherwise set forth herein, the Administrative Agent may (and upon the written request of the Required Banks the Administrative Agent shall) take or refrain from taking any action under this Agreement or any other Loan Document, including giving its written consent to any modification of or amendment to and waiving in writing compliance with any covenant or condition in this Agreement or any other Loan Document or any Default or Event of Default, all of which actions shall be binding upon all of the Banks; provided, however, that:

(i) Without the written consent of the Required Banks (other than Delinquent Banks during the existence of a Delinquency Period so long as such Delinquent Bank is treated the same as the other Banks with respect to any actions enumerated below), no written modification of, amendment to, consent with respect to, waiver of compliance with or waiver of a Default under, any of the Loan Documents shall be made, including without limitation, Sections 7B.1 through 7B.14 of this Agreement, the related defined terms or this Section 10.6(i) shall be made.

(ii) Without the written consent of such Banks as own 100% of the Percentage Interests (other than Delinquent Banks during the existence of a Delinquency Period so long as such Delinquent Bank is treated the same as the other Banks with respect to any actions enumerated below):

(a) No reduction shall be made in (A) the amount of principal of any of the Loans or reimbursement obligations for payments made under Letters of Credit, (B) the interest rate on the Loans or (C) the Letter of Credit issuance fees (excluding, however, Letter of Credit processing/application fees, the amount of which shall be within the sole discretion of each Letter of Credit Issuer) or commitment (non-usage) fees.

(b) No change shall be made in the stated time of payment of all or any portion of any of the Loans or interest thereon or reimbursement of payments made under Letters of Credit or fees relating to any of the foregoing payable to all of the Banks and no waiver shall be made of any Default under Section 9.1(i) and (ii) hereof.

(c) No increase shall be made in the amount, or extension of the term, of either Commitment beyond that provided for under Article II.

(d) Except as otherwise provided in the Intercreditor Agreement, no alteration shall be made of the Banks’ rights of set-off contained herein or in the other Loan Documents.

(e) Except as otherwise provided in the Intercreditor Agreement, no release of any Collateral shall be made (except that the Collateral Agent may release particular items of Collateral in dispositions permitted by the Security Documents in accordance with the terms and provisions of the Intercreditor Agreement and may release all Collateral upon payment in full of the Loans evidenced by the Notes and termination of the Commitments together with payment of all of the Private Placement Notes and Parity Debt without the written consent of the Banks).

(f) No amendment to or modification of this Section 10.6(ii) shall be made.

(g) Without the written consent of the Swingline Lender, no provision of Section 2.5 may be amended.

(h) Notwithstanding anything in this Agreement to the contrary, in the event that the Borrower shall have paid in full the Private Placement Notes from any source other than Credit Obligations secured on a parity basis with the Banks, the Banks and the Administrative Agent hereby agree and acknowledge that this Agreement shall be deemed amended (without further action on the part of the Borrower, the Banks or the Administrative Agent) to delete Sections 7A.16 and 7B.14 in their entirety and that such sections shall have no force or effect as of the date of such payment in full and thereafter.

10.7 Administrative Agent’s Resignation. The Administrative Agent may resign at any time by giving at least 30 days’ prior written notice of its intention to do so to each other of the Banks and the Borrower and upon the appointment by the Required Banks of a successor Administrative Agent satisfactory to the Borrower. If no successor Administrative Agent shall have been so appointed and shall have accepted such appointment within 45 days after the retiring Administrative Agent’s giving of such notice of resignation, then the retiring Administrative Agent may with the consent of the Borrower, which shall not be unreasonably withheld, appoint a successor Administrative Agent which shall be a bank or a trust company

organized under the laws of the United States of America or any state thereof and having a combined capital, surplus and undivided profit of at least $50,000,000; provided, however, that any successor Administrative Agent appointed under this sentence may be removed upon the written request of the Required Banks, which request shall also appoint a successor Administrative Agent satisfactory to the Borrower. Upon the appointment of a new Administrative Agent hereunder, the term “Administrative Agent” shall for all purposes of this Agreement thereafter mean such successor. After any retiring Administrative Agent’s resignation hereunder as an Administrative Agent, or the removal hereunder of any successor Administrative Agent, the provisions of this Agreement shall continue to inure to the benefit of such Administrative Agent as to any actions taken or omitted to be taken by it while it was an Administrative Agent under this Agreement.

10.8 Concerning the Administrative Agent.

10.8.1 Action in Good Faith. The Administrative Agent and its respective officers, directors, employees and Administrative Agent shall be under no liability to any of the Banks or to any future holder of any interest in the Indebtedness for any action or failure to act taken or suffered in good faith, and any action or failure to act in accordance with an opinion of its counsel shall conclusively be deemed to be in good faith. The Administrative Agent shall in all cases be entitled to rely, and shall be fully protected in relying, on instructions given to the Administrative Agent by the Required Holders of the Notes evidencing the Indebtedness as provided in this Agreement.

10.8.2 No Implied Duties. The Administrative Agent shall have and may exercise such powers as are specifically delegated to the Administrative Agent under this Agreement or any other Loan Document together with all other powers incidental thereto. The Administrative Agent shall have no implied duties to any Person or any obligation to take any action under this Agreement or any other Loan Document except for action specifically provided for in this Agreement or any other Loan Document to be taken by the Administrative Agent. Before taking any action under this Agreement or any other Loan Document, the Administrative Agent may request an appropriate specific indemnity satisfactory to it from each Bank in addition to the general indemnity provided for in Section 10.11. Until the Administrative Agent has received such specific indemnity, the Administrative Agent shall not be obligated to take (although such Agent may in its sole discretion take) any such action under this Agreement or any other Loan Document. Each Bank confirms that the Administrative Agent does not have a fiduciary relationship to them under the Loan Documents. The Borrower and its Subsidiaries party hereto confirm that neither the Administrative Agent nor any other Bank has a fiduciary relationship to them under the Loan Documents.

10.8.3 Validity. The Administrative Agent shall not be responsible to any Bank or any future holder of any interest in the Loans and Indebtedness (a) for the legality, validity, enforceability or effectiveness of this Agreement or any other Loan Document, (b) for any recitals, reports, representations, warranties or statements contained in or made in connection with this Agreement or any other Loan Document, (c) for the existence or value of any assets included in any security for the Loans and Indebtedness,

(d) for the effectiveness of any Lien purported to be included in the Collateral, (e) for the specification or failure to specify any particular assets to be included in the Collateral, or (f) unless the Administrative Agent shall have failed to comply with Section 10.8.1, for the perfection of the security interests in the Collateral.

10.8.4 Compliance. The Administrative Agent shall not be obligated to ascertain or inquire as to the performance or observance of any of the terms of this Agreement or any other Loan Document; and in connection with any extension of credit under this Agreement or any other Loan Document, the Administrative Agent shall be fully protected in relying on a certificates of the Borrower as to the fulfillment by the Borrower of any conditions to such extension of credit.

10.8.5 Employment of Agents and Counsel. The Administrative Agent may execute any of their respective duties as Administrative Agent under this Agreement or any other Loan Document by or through employees, agents and attorneys-in-fact and shall not be responsible to any of the Banks, the Borrower for the default or misconduct of any such Administrative Agent or attorneys-in-fact selected by the Agent acting in good faith. The Administrative Agent shall be entitled to advice of counsel concerning all matters pertaining to the agency hereby created and its duties hereunder or under any other Loan Document.

10.8.6 Reliance on Documents and Counsel. The Administrative Agent shall be entitled to rely, and shall be fully protected in relying, upon any affidavit, certificate, cablegram, consent, instrument, letter, notice, order, document, statement, telecopy, telegram, telex or teletype message or writing reasonably believed in good faith by the Administrative Agent to be genuine and correct and to have been signed, sent or made by the Person in question, including any telephonic or oral statement made by such Person, and, with respect to legal matters, upon an opinion or the advice of counsel selected by such Agent.

10.8.7 Administrative Agent’s Reimbursement. Each of the Banks severally agrees to reimburse the Administrative Agent, in the amount of such Bank’s Percentage Interest, for any reasonable expenses not reimbursed by the Borrower (without limiting the obligation of the Borrower to make such reimbursement): (a) for which the Administrative Agent is entitled to reimbursement by the Borrower under this Agreement or any other Loan Document, and (b) after the occurrence of a Default, for any other reasonable expenses incurred by the Administrative Agent on the Banks’ behalf in connection with the enforcement of the Banks’ rights under this Agreement or any other Loan Document.

10.9 Rights as a Bank. With respect to any Loan(s) or advance(s) extended by it hereunder, the Administrative Agent shall have the same rights, obligations and powers hereunder as any other Bank and may exercise such rights and powers as though it were not an Agent, and unless the context otherwise specifies, the Administrative Agent shall be treated in its individual capacity as though it was not the Administrative Agent hereunder. Without limiting the generality of the foregoing, the Percentage Interest of the Administrative Agent and the

Syndication Agent shall be included in any computations of Percentage Interests. The Administrative Agent and its Affiliates may accept deposits from, lend money to, act as trustee for and generally engage in any kind of banking or trust business with the Borrower, any of its Subsidiaries or any Affiliate of any of them and any Person who may do business with or own an equity interest in the Borrower, any of its Subsidiaries or any Affiliate of any of them, all as if such Administrative Agent were not the Administrative Agent and without any duty to account therefor to the other Banks.

10.10 Independent Credit Decision. Each of the Banks acknowledges that it has independently and without reliance upon the Administrative Agent, based on the financial statements and other documents referred to in Section 8.4, on the other representations and warranties contained herein and on such other information with respect to the Borrower and its Subsidiaries as such Bank deemed appropriate, made such Bank’s own credit analysis and decision to enter into this Agreement and to make the extensions of credit provided for hereunder. Each Bank represents to the Administrative Agent that such Bank will continue to make its own independent credit and other decisions in taking or not taking action under this Agreement or any other Loan Document. Each Bank expressly acknowledges that the Administrative Agent nor any of its officers, directors, employees, agents, attorneys-in-fact or Affiliates has made any representations or warranties to such Bank, and no act by the Administrative Agent taken under this Agreement or any other Loan Document, including any review of the affairs of the Borrower and its Subsidiaries, shall be deemed to constitute any representation or warranty by the Administrative Agent. Except for notices, reports and other documents expressly required to be furnished to each Bank by the Administrative Agent under this Agreement or any other Loan Document, the Administrative Agent shall not have any duty or responsibility to provide any Bank with any credit or other information concerning the business, operations, property, condition, financial or otherwise, or creditworthiness of the Borrower or any Subsidiary which may come into the possession of the Administrative Agent or any of its officers, directors, employees, agents, attorneys-in-fact or Affiliates.

10.11 Indemnification. The holders of the Indebtedness shall indemnify the Administrative Agent and its officers, directors, employees and agents (to the extent not reimbursed by the Borrower and without limiting the obligation of the Borrower to do so), pro rata in accordance with their respective Percentage Interests, from and against any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind whatsoever which may at any time be imposed on, incurred by or asserted against the Administrative Agent or such Persons relating to or arising out of this Agreement, any other Loan Document, the transactions contemplated hereby or thereby, or any action taken or omitted by the Administrative Agent in connection with any of the foregoing; provided, however, that the foregoing shall not extend to actions or omissions which are taken by the Administrative Agent with gross negligence or willful misconduct.

10.12 Procedure for Commitment Increases and Additional Banks. This Agreement permits certain increases in a Bank’s Commitments and the admission of Additional Banks providing new Commitments, it being acknowledged that the existing aggregate Maximum Commitment Amount of the Banks listed in the Lenders Schedule is $75,000,000 and that this Agreement (without further amendment or modification), by virtue of the provisions of Section 2.7

contemplates and permits Commitments in the additional aggregate maximum amount of $75,000,000 (in no event shall the Maximum Amount of Revolving Credit exceed $150,000,000). Any amendment hereto for such an increase or addition shall be in the form attached hereto as Exhibit 10.12 (“Increase Request Agreement”) and shall only require the written signatures of the Administrative Agent, the Borrower and the Bank(s) being added or increasing their Commitments. In addition, within a reasonable time after the effective date of any increase, the Administrative Agent shall, and is hereby authorized and directed to, revise the Lenders Schedule reflecting such increase and shall distribute such revised Lenders Schedule to each of the Banks and the Borrowers, whereupon such revised Lenders Schedule shall replace the old Lenders Schedule and become part of this Agreement. On the Business Day following any such increase, all outstanding Base Rate Loans shall be reallocated among the Banks (including any newly added Banks) in accordance with the Banks’ respective revised Percentage Interests. Eurodollar Loans shall not be reallocated among the Banks prior to the expiration of the applicable Eurodollar Interest Period in effect at the time of any such increase.

ARTICLE XI

ASSIGNMENTS/PARTICIPATIONS

11. Successors and Assigns; Bank Assignment and Participations. Any reference in this Agreement to any party hereto shall be deemed to include the successors and assigns of such party, and all covenants and agreements by or on behalf of the Borrower, the Administrative Agent or the Banks that are contained in this Agreement or any other Loan Documents shall bind and inure to the benefit of their respective successors and assigns; provided, however, that (a) the Borrower may not assign its rights or obligations under this Agreement except for mergers or liquidations permitted by Section 7B.7, and (b) the Banks shall be not entitled to assign their respective Percentage Interests in the Loans evidenced by the Notes hereunder except as set forth below in this Section 11.

11.1 Assignments by Banks.

11.1.1 Assignees and Assignment Procedures. Each Bank may (i) without the consent of the Administrative Agent or the Borrower if the proposed assignee is already a Bank hereunder or a Wholly Owned Subsidiary of the same corporate parent of which the assigning Bank is a Subsidiary, or (ii) otherwise with the consents of the Administrative Agent and (so long as no Event of Default exists) the Borrower (which consents will not be unreasonably withheld), in compliance with applicable laws in connection with such assignment, assign to one or more commercial banks or other financial institutions (each, an “Assignee”) all or a portion of its interests, rights and obligations under this Agreement and the other Loan Documents, including all or a portion, which need not be pro rata among the Loans and the Letter of Credit Exposure, of its Commitments, the portion of the Loans and Letter of Credit Exposure at the time owing to it and the Notes held by it, but excluding its rights and obligations as the Administrative Agent; provided, however, that:

(i) the aggregate amount of the Commitments of the assigning Bank subject to each such assignment to any Assignee other than another Bank (determined as of the date the Assignment and Acceptance with respect to such assignment is delivered to the Administrative Agent) shall be not less than $1,000,000 and in increments of $500,000; and

(ii) the parties to each such assignment shall execute and deliver to the Administrative Agent an Assignment and Acceptance (the “Assignment and Acceptance”) in the form satisfactory to the Administrative Agent and the Collateral Agent, together with the Note or Notes subject to such assignment and a processing and recordation fee of $500 payable to the Administrative Agent by the assigning Bank or the Assignee.

(A) the Assignee shall be a party hereto and, to the extent provided in such Assignment and Acceptance, have the rights and obligations of a Bank under this Agreement; and

(B) the assigning Bank shall, to the extent provided in such assignment, be released from its obligations under this Agreement (and, in the case of an Assignment and Acceptance covering all or the remaining portion of an assigning Bank’s rights and obligations under this Agreement, such Bank shall cease to be a party hereto but shall continue to be entitled to the benefits of the Applicable Rate provisions hereof, as well as to any fees accrued for its account hereunder and not yet paid).

11.1.2 Terms of Assignment and Acceptance. By executing and delivering an Assignment and Acceptance, the assigning Bank and Assignee shall be deemed to confirm to and agree with each other and the other parties hereto as follows:

(a) other than the representation and warranty that it is the legal and beneficial owner of the interest being assigned thereby free and clear of any adverse claim, such assigning Bank makes no representation or warranty and assumes no responsibility with respect to any statements, warranties or representations made in or in connection with this Agreement or the execution, legality, validity, enforceability, genuineness, sufficiency or value of this Agreement, any other Loan Document or any other instrument or document furnished pursuant hereto;

(b) such assigning Bank makes no representation or warranty and assumes no responsibility with respect to the financial condition of the Borrower and its Subsidiaries or the performance or observance by the Borrower or any of its Subsidiaries of any of its obligations under this Agreement, any other Loan Document or any other instrument or document furnished pursuant hereto;

(c) such Assignee confirms that it has received a copy of this Agreement, together with copies of the most recent quarterly or annual financial statements delivered pursuant to Section 7A.1 and such other documents and information as it has deemed appropriate to make its own credit analysis and decision to enter into such Assignment and Acceptance;

(d) such Assignee will independently and without reliance upon the Administrative Agent, such assigning Bank or any other Bank, and based on such documents and information as it shall deem appropriate at the time, continue to make its own credit decisions in taking or not taking action under this Agreement;

(e) such Assignee appoints and authorizes the Administrative Agent to take such action as the Administrative Agent on its behalf and to exercise such powers under this Agreement as are delegated to the Administrative Agent by the terms hereof, together with such powers as are reasonably incidental thereto; and

(f) such Assignee agrees that it will perform in accordance with the terms of this Agreement all the obligations which are required to be performed by it as a Bank.

11.1.3 Register. The Administrative Agent, shall maintain at its main Tulsa, Oklahoma, banking office a register (the “Register”) for the recordation of (a) the names and addresses of the Banks and the Assignees which assume rights and obligations pursuant to an assignment under Section 11.1.1, (b) the Percentage Interest of each such Bank as set forth in Section 11.1 and (c) the amount of the Loans and Letter of Credit Exposure owing to each Bank from time to time. The entries in the Register shall be conclusive, in the absence of manifest error, and the Borrower, BOK, as such Administrative Agent and the Banks may treat each Person whose name is registered therein for all purposes as a party to this Agreement. The Register shall be available for inspection by the Borrower or any Bank at any reasonable time and from time to time upon reasonable prior notice.

11.1.4 Acceptance of Assignment and Assumption. Upon its receipt of a completed Assignment and Acceptance executed by an assigning Bank and an Assignee, in exchange for the Notes subject to such assignment, together with the Note or Notes subject to such assignment, and the processing and recordation fee referred to in Section 11.1.1, the Administrative Agent shall (a) accept such Assignment and Acceptance, (b) record the information contained therein in the Register and (c) give prompt notice thereof to the Borrower. Within five (5) Business Days after receipt of notice, the Borrower, at its own expense, shall execute and deliver to the Administrative Agent, in exchange for the surrendered Note or Notes, a new Note or Notes to the order of such Assignee in a principal amount equal to the applicable Commitments and Loans assumed by it pursuant to such Assignment and Acceptance and, if the assigning Bank has retained

Commitments and Loans, a new Note or Notes to the order of such assigning Bank in a principal amount equal to the applicable Commitments and its Percentage Interest in the Loans retained by it. Such new Note or Notes shall be in an aggregate principal amount equal to the aggregate principal amount of such surrendered Note or Notes, and shall be dated the date of the surrendered Note or Notes which it or they replace. All such Notes so replaced shall be delivered by the Administrative Agent to the Borrower or, alternatively, at such Administrative Agent’s election, marked appropriately to evidence the replacement thereof by such replacement Note(s).

11.1.5 Federal Reserve Bank. Notwithstanding the foregoing provisions of this Section 11, any Bank may at any time pledge or assign all or any portion of such Bank’s rights under this Agreement and the other Loan Documents to a Federal Reserve Bank; provided, however, that no such pledge or assignment shall release such Bank from such Bank’s obligations hereunder or under any other Loan Document.

11.1.6 Further Assurances. The Borrower and its Subsidiaries shall sign such documents and take such other actions from time to time reasonably requested by an Assignee to enable it to share in the benefits of the rights created by the Loan Documents.

11.2 Credit Participants. Each Bank may, without the consent of the Borrower and with the consent of the Administrative Agent, in compliance with applicable laws in connection with such participation, sell to one or more commercial banks or other financial institutions (each a “Credit Participant”) participations in all or a portion of its interests, rights and obligations under this Agreement and the other Loan Documents (including all or a portion of its Commitments, the Loans and Letter of Credit exposure owing to it and the Notes held by it); provided, however, that:

(i) such Bank’s obligations under this Agreement shall remain unchanged;

(ii) such Bank shall remain solely responsible to the other parties hereto for the performance of such obligations;

(iii) the Credit Participant shall be entitled to the benefit of any cost protection provisions contained in the Credit Agreement, but shall not be entitled to receive any greater payment thereunder than the selling Bank would have been entitled to receive with respect to the interest so sold if such interest had not been sold; and

(iv) the Borrower, the Administrative Agent and the other Banks shall continue to deal solely and directly with such Bank in connection with such Bank’s rights and obligations under this Agreement, and such Bank shall retain the sole right as one of the Banks to vote with respect to the enforcement of the obligations of the Borrower relating to the Loans and Letter of Credit Exposure and the approval of any amendment, modification or waiver of any provision of this Agreement (other than amendments, modifications, consents or waivers described in Section 10.6(ii)).

Borrower agrees, to the fullest extent permitted by applicable law, that any Credit Participant and any Bank purchasing a participation from another Bank pursuant to Section 11.1 may exercise all rights of payment (including the right of set-off), with respect to its participation as fully as if such Credit Participant or such Bank were the direct creditor of the Borrower and a Bank hereunder in the amount of such participation. Upon receipt of notice of the address of each Credit Participant, the Borrower shall thereafter supply such Credit Participants with the same information and reports communicated to the Banks. The Borrower hereby acknowledges and agrees that Credit Participants shall be deemed a holder of the applicable Notes to the extent of their respective participation, and the Borrower hereby waives its right, if any, to offset amounts owing to the Borrower from the Banks against each Credit Participant’s portion of the applicable Notes.

11.3 Replacement of Bank. In the event that any Bank or, to the extent applicable, any Credit Participant (the “Affected Bank”):

(a) fails to perform its obligations to fund any portion of the Loans or to issue any Letter of Credit when required to do so by the terms of the Loan Documents, or fails to provide its portion of any Eurodollar Pricing Option pursuant to Section 3.2.1 or on account of a Bank Legal Requirement as contemplated by Section 3.2.5;

(b) demands payment under the Reserve provisions of Section 3.5, the Tax provisions of Section 3.6, the Capital Adequacy provisions of Section 3.7 or the Regulatory Change provisions in Section 3.8 in an amount the Borrower deems materially in excess of the amounts with respect thereto demanded by the other Banks; or

(c) refuses to consent to a proposed amendment, modification, waiver or other action requiring consent of the holders of 100% of the Percentage Interests under Section 10.6(ii) that is consented to by the other Banks;

then, so long as no Event of Default exists, the Borrower shall have the right to seek a replacement Bank which is reasonably satisfactory to the Administrative Agent (the “Replacement Bank”). The Replacement Bank shall purchase the interests of the Affected Bank in the Loans, Letters of Credit and its Commitments and shall assume the obligations of the Affected Bank hereunder and under the other Loan Documents upon execution by the Replacement Bank of an Assignment and Acceptance and the tender by it to the Affected Bank of a purchase price agreed between it and the Affected Bank (or, if they are unable to agree, a purchase price in the amount of the Affected Bank’s Percentage Interest in the Loans and Letter of Credit Exposure, or appropriate credit support for contingent amounts included therein, and all other outstanding Credit Obligations then owed to the Affected Bank). Such assignment by the Affected Bank shall be deemed an early termination of any Eurodollar Pricing Option to the extent of the Affected Bank’s portion thereof, and the Borrower will pay to the Affected Bank any resulting amounts due under Section 3.2.4. Upon consummation of such assignment, the Replacement Bank shall become party to this Agreement as a signatory hereto and shall have all the rights and obligations of the Affected Bank under this Agreement and the other Loan Documents with a Percentage Interest equal to the Percentage Interest of the Affected Bank, the

Affected Bank shall be released from its obligations hereunder and under the Loan Documents, and no further consent or action by any party shall be required. Upon the consummation of such assignment, the Borrower, the Administrative Agent and the Affected Bank shall make appropriate arrangements so that a new Note or Notes are issued to the Replacement Bank. The Borrower shall sign such documents and take such other actions reasonably requested by the Replacement Bank to enable it to share in the benefits of the rights created by the Loan Documents. Until the consummation of an assignment in accordance with the foregoing provisions of this Section 11.3, the Borrower shall continue to pay the Affected Bank any Loan Obligations as they become due and payable.

extension of credit, or other financial services product. What this means for borrowers: When a borrower opens an account, the Banks will ask for the borrower’s name, residential address, tax identification number, and other information that will allow the Banks to identify the borrower, including the borrower’s date of birth if the borrower is an individual. The Banks may also ask, if the borrower is an individual, to see the borrower’s driver’s license or other identifying documents, and, if the borrower is not an individual, to see the borrower’s legal organizational documents or other identifying documents. The Banks will verify and record the information the Banks obtain from the borrower pursuant to the USA PATRIOT Act, and will maintain and retain that record in accordance with the regulations promulgated under the USA PATRIOT Act.

12.19 Not a Reportable Transaction. The parties signatory hereto acknowledge and stipulate and the Borrower represents to the Administrative Agent, the Co-Agent and the Banks that the transactions contemplated by this Agreement do not constitute a “Reportable Event” as that term is described and defined in regulations of the Treasury Department of the United States.

12.20 Counterparts. This Agreement may be executed in any number of counterparts, all of which taken together shall constitute one and the same instrument. Delivery of an executed counterpart of a signature page of this Agreement by telecopier or facsimile shall be as effective as delivery of a manually executed counterpart hereof.

Pursuant to Section 10.12 of the Credit Agreement, the Borrower has the right to obtain additional Commitments upon satisfaction of certain conditions.
