ACQUISITION OF ASSETS On September 3, 1997, Pioneer Natural Resources Company ("Pioneer") entered into an agreement (the "Combination Agreement") to acquire the Canadian and Argentine oil and gas businesses of Chauvco Resources Ltd. ("Chauvco"), a publicly traded independent oil and gas company based in Calgary, Canada (the "Transaction"), and to spin-off to Chauvco shareholders Chauvco's Gabonese oil and gas operations and other international interests through Chauvco's existing subsidiary, Chauvco Resources International Ltd. ("CRI"). The Transaction was completed on December 18, 1997. In accordance with the Combination Agreement, each holder of Chauvco common shares ("Chauvco Shareholder") received for each Chauvco common share held (i) one share of CRI and (ii) in certain cases, at the election of the Chauvco Shareholder, either the number of Pioneer common shares or shares exchangeable into Pioneer shares ("Exchangeable Shares") or a combination of both determined by multiplying each Chauvco common share held by an exchange ratio of 0.493827. In total, the acquisition consideration paid to the shareholders of Chauvco was approximately $946 million, consisting of the issuance of 14,015,010 shares of Pioneer common stock and 10,901,924 Exchangeable Shares and the assumption of $228 million of long-term debt. Cash payments were made in lieu of issuing fractional shares. For a detailed description of the assets acquired and liabilities assumed from Chauvco, see the Joint Management Information Circular and Proxy Statement dated November 14, 1997 incorporated herein by reference. In accordance with the provisions of Accounting Principles Board No. 16, "Business Combinations," ("APB 16"), the Transaction was treated as an acquisition of Chauvco by Pioneer. See "Item 7. Financial Statements and Exhibits" for the preliminary allocation of the total purchase price of Chauvco to the acquired assets and liabilities based upon the estimated fair values assigned to each of the significant assets acquired and liabilities assumed. Any future adjustments to the allocation of the purchase price are not anticipated to be material to Pioneer's financial statements. ITEM 5. OTHER EVENTS Tender Offer for Senior Subordinated Notes. On November 14, 1997, Pioneer Natural Resources USA, Inc. ("Pioneer USA"), a wholly-owned subsidiary of Pioneer, announced an offer to purchase for cash any and all of its $264 million 11 5/8% Senior Subordinated Discount Notes Due 2006 ("11 5/8% Notes") and its $325 million 10 5/8% Senior Subordinated Notes Due 2006 ("10 5/8% Notes") (collectively the "Mesa Notes") for a purchase price of $1,171.40 and $829.90, respectively, per $1,000 tendered plus any interest accrued on the 10 5/8% Notes (the "Tender Offer"). As of December 15, 1997, the offer expiration date, the respective Mesa Note holders had tendered approximately $319.1 million, or 98%, of the 10 5/8% Notes and approximately $241.5 million, or 91%, of the 11 5/8% Notes. On December 18, 1997, Pioneer USA paid holders an aggregate of approximately $574.3 million for the principal amount tendered on the Mesa Notes, and Pioneer USA paid to the holders of the 10 5/8% Notes accrued interest through the payment date of the Tender Offer of approximately $15.7 million. As a result of the Tender Offer, Pioneer will recognize after-tax extraordinary loss on early extinguishment of debt of $11.9 million during the fourth quarter of 1997. Pioneer USA financed the purchase price of the Mesa Notes tendered in the offer with borrowings under its bank credit facility. In connection with the Tender Offer, the holders of the requisite percentage of each outstanding issue of Mesa Notes approved amendments to the respective indentures governing the Mesa Notes which eliminated or modified most of the restrictive covenants contained in the indentures. Such amendments became effective on December 18, 1997, upon completion of the Tender Offer. American Cometra Acquisition. On December 19, 1997, Pioneer completed the acquisition of assets in the East Texas Basin from affiliates of American Cometra, Inc. ("ACI") and Rockland Pipeline Co. ("Rockland"), both subsidiaries of Electrafina S.A. of Belgium ("American Cometra Acquisition"). The total consideration paid was approximately $126 million, consisting of $80 million in cash and 1.7 million shares of Pioneer's common stock. Pioneer acquired ACI's producing wells, acreage, seismic data, royalties and mineral interests, and Rockland's gathering system, pipeline and gas processing plant in the East Texas Basin. This acquisition establishes a critical mass and core area in the East Texas Basin for Pioneer and provides it with a major presence in the Cotton Valley Reef trend. 1997 Asset Divestitures. During December 1997, Pioneer completed the sale of certain non-strategic properties for cash proceeds of approximately $103 million (the "1997 Asset Divestitures"). These divestitures involve approximately 800 properties and represent less than 3% of Pioneer's total reserve base and about 1% of Pioneer's daily production. Proceeds from these divestitures were primarily used to fund the American Cometra Acquisition described above. Credit Facility Agreements. On December 18, 1997, Pioneer amended and restated its domestic credit facilities ("United States Credit Facility") in order to substitute Pioneer as the borrower in place of Pioneer USA. The United States Credit Facility consists of two credit facility agreements. The primary facility provides for a $1.075 billion revolving line of credit with a maturity date of August 7, 2002. The additional facility provides for a $300 million line of credit with a maturity date of August 5, 1998. Advances on the United States Credit Facility bear interest, at the borrower's option, based on (a) the prime rate of NationsBank of Texas, N.A., (b) a Eurodollar rate (substantially equal to LIBOR), adjusted for the reserve requirement as determined by the Board of Governors of the Federal Reserve System with respect to transactions in Eurocurrency liabilities ("LIBOR Rate"), or (c) a competitive bid rate as quoted by the lenders electing to participate following the borrower's request. Advances that bear a LIBOR Rate have periodic maturities, at the borrower's option, of one, two, three, six, nine or twelve months. Advances that bear competitive bid rates have periodic maturities, at the borrower's option, of not less than 15 days nor more than 360 days. The interest rates on LIBOR Rate advances vary with interest rate margins ranging from 18 basis points to 45 basis points. The interest rate margin is determined by a grid based upon the long-term public debt rating of Pioneer's senior unsecured indebtedness. Pioneer's obligations are guaranteed by Pioneer USA and certain other U.S. subsidiaries, and are secured by a pledge of 65% of the capital stock of certain non-U.S. subsidiaries. The United States Credit Facility has been used to refinance the debt of Parker & Parsley Petroleum Company and MESA Inc. in their merger on August 7, 1997, to fund the offer to purchase the Mesa Notes, to fund the acquisition of assets from ACI and Rockland, and for other general corporate purposes. Pioneer also executed a $100 million note (the "Term Note"), dated as of December 22, 1997, payable to NationsBank of Texas, N.A. for use for working capital. The Term Note has a maturity date of April 1, 1999, and bears interest at the borrower's option, at the rates set forth in clauses (a) and (b) of this paragraph. Also on December 18, 1997, Pioneer refinanced all of Chauvco's outstanding debt by establishing a $290 million Canadian credit facility under which the borrower is Chauvco, and Pioneer and certain of its subsidiaries (not including Pioneer USA) provide guarantees. Restructuring. On December 30, 1997, Pioneer and Pioneer USA completed a restructuring that resulted in Pioneer becoming the primary obligor on the $28.4 million of Mesa Notes that were not tendered and on the $300 million of Parker & Parsley Petroleum Company's 8 7/8% Senior Notes Due 2005 and 8 1/4% Senior Notes Due 2007 ("Parker & Parsley Notes"). Pioneer USA has guaranteed the payment of principal and interest on the Parker & Parsley Notes, but has not guaranteed the Mesa Notes. The guarantee of the Parker & Parsley Notes will terminate if Pioneer USA is released from its guarantees of Pioneer's United States Credit Facility. Fourth Quarter Charges. During the fourth quarter of 1997, Pioneer will recognize certain charges which adversely affect Pioneer's financial results. In addition to the $11.9 million after-tax extraordinary loss related to the Tender Offer noted above, Pioneer estimates that it will recognize after-tax charges of between $7 - $10 million for the purchase of 3-D seismic data and approximately $3 million resulting from the write-off of an unsuccessful well in Guatemala. The decline of oil and gas prices during the fourth quarter of 1997 will also have an adverse effect on Pioneer's financial results. 3 4 ITEM 7. FINANCIAL STATEMENTS AND EXHIBITS In accordance with the Combination Agreement, each holder of Chauvco common shares received for each Chauvco common share held (i) one CRI Share and (ii) in certain cases, at the election of the Chauvco Shareholder, either the number of shares of Pioneer common stock or Exchangeable Shares, or a combination of both, determined by multiplying each Chauvco Common Share held by an exchange ratio of .493827. In total, 14,015,010 shares of Pioneer common stock and 10,901,924 Exchangeable Shares were issued upon completion of the Transaction. Cash payments were made in lieu of issuing approximately 89 fractional shares of Pioneer common stock and 18 fractional shares of Exchangeable Shares. In accordance with APB 16, the Transaction was treated as an acquisition of Chauvco by Pioneer. The value of Pioneer common stock for use in determining the aggregate purchase consideration allocated to the acquired assets and liabilities of Chauvco ("Consideration") is $27.625, which represents the market price of Pioneer common stock on December 18, 1997, the date of the shareholder vote for the Transaction (the "Chauvco Meeting"). In August 1997, the stockholders of Pioneer's predecessor entities, Parker & Parsley Petroleum Company ("Parker & Parsley") and MESA Inc. ("Mesa"), approved an Amended and Restated Agreement and Plan of Merger ("Merger Agreement") that resulted in the formation of Pioneer ("Parker/Mesa Merger"). In accordance with the provisions of APB 16, the merger was treated as an acquisition of Mesa by Parker & Parsley. As a result, the historical financial statements of Pioneer are those of Parker & Parsley and present the addition of Mesa's assets and liabilities as an acquisition by Pioneer in August 1997, and all references to Pioneer contained herein are references to Parker & Parsley for dates prior to the Parker/Mesa Merger. The unaudited pro forma combined balance sheet and statements of operations have been prepared to give effect to certain transactions as described below. The unaudited pro forma combined balance sheet of Pioneer as of September 30, 1997 has been prepared to give effect to the Transaction as if such transaction had occurred on September 30, 1997. In accordance with the provisions of APB 16, the Transaction has been accounted for as a purchase of Chauvco by Pioneer. The unaudited pro forma combined statements of operations of Pioneer for the nine months ended September 30, 1997 and for the year ended December 31, 1996 have been prepared to give effect to the Transaction, Parker/Mesa Merger and certain events described below for Pioneer, Chauvco and Mesa as if the Transaction, Parker/Mesa Merger and such events had occurred on January 1, 1996. Pro Forma Pioneer has been prepared to give effect to the acquisition of Pro Forma Mesa by Adjusted Pioneer, both as defined below. Pro Forma Chauvco has been prepared to give effect to the distribution of CRI Shares and the rights to the Alliance Pipeline to the Chauvco Shareholders. Adjusted Pioneer has been prepared to give effect to (i) the sale of certain wholly-owned Australian subsidiaries in March 1996 and the sale of Bridge Oil Timor Sea, Inc. in June 1996 (collectively, the "Australasian Assets Sold"), (ii) the aggregate effect of the sale of certain nonstrategic domestic oil and gas properties, gas plants, contract rights and related assets sold during the period from January 2, 1996 to December 31, 1996 (collectively, the "1996 Assets Sold") and (iii) the exchange of Pioneer's 6 1/4% Cumulative Monthly Income Convertible Preferred Shares ("Preferred Shares") to Pioneer common stock in August 1997. Pro Forma Mesa has been prepared to give effect to the Recapitalization (as described in Note 1. of Notes to Unaudited Pro Forma Combined Financial Statements), which entailed issuing $265 million in new preferred equity and repaying and refinancing substantially all of Mesa's $1.2 billion of then existing long-term debt, and the Greenhill acquisition, including additional borrowings to finance such acquisition. 4 5 The historical consolidated financial statements for Chauvco and CRI were prepared under Canadian GAAP and in Canadian dollars. For these unaudited pro forma combined financial statements, the historical financial information of Chauvco, CRI and the Alliance Pipeline project have been converted to U.S. dollars using the period end exchange rate for the balance sheet and the average exchange rate for the statements of operations for the respective periods. These unaudited pro forma combined financial statements also contain certain adjustments to conform the historical Chauvco financial statements to U.S. GAAP and successful efforts method of accounting as used by Pioneer after eliminating the balances or activity associated with CRI and the Alliance Pipeline. In addition, certain reclassifications have been made to Chauvco's historical consolidated financial statements to conform to Pioneer's financial statement presentation. The unaudited pro forma combined financial statements included herein are not necessarily indicative of the results that might have occurred had the transactions taken place at the beginning of the period specified and are not intended to be a projection of future results. In addition, future results may vary significantly from the results reflected in the accompanying unaudited pro forma combined financial statements because of normal production declines, changes in product prices, future acquisitions and divestitures, future development and exploration activities, and other factors. The following unaudited pro forma combined financial statements should be read in conjunction with (i) the Consolidated Financial Statements (and the related notes) of Pioneer included in its Quarterly Report on Form 10-Q for the nine months ended September 30, 1997, (ii) the Consolidated Financial Statements (and the related notes) of both Parker & Parsley and Mesa included in their respective Annual Reports on Form 10-K and Form 10-K/A for the year ended December 31, 1996 and their respective Quarterly Reports on Form 10-Q for the three months ended March 31, 1997 and the six months ended June 30, 1997 and (iii) the Consolidated Financial Statements (and the related notes) of Chauvco for the nine months ended September 30, 1997 and for the three-year period ended December 31, 1996. 5 6 PIONEER NATURAL RESOURCES COMPANY UNAUDITED PRO FORMA COMBINED BALANCE SHEET AS OF SEPTEMBER 30, 1997 (in thousands) ASSETS Pro Forma Pro Forma Pioneer ------------ Combined Pro Forma Chauvco Adjustments --------------------- Combined ----------- Current assets: Cash and cash equivalents Restricted cash Accounts receivable Inventories Deferred income taxes Other current assets --------------------- ----------- Total current assets --------------------- 185,952 ----------- $ 40,631 1,716 128,093 6,839 3,600 5,073 514,828 ----------- ----------- $ 3,796,743 =========== $ 4,930,221 =========== ----------- Total current liabilities --------------------- 136,577 ----------- $ Long-term debt, less current maturities Other noncurrent liabilities Deferred income taxes 792,653 33,129 (164,554)(a) 401,462 (a) (310,954) 41,059 1,716 166,349 8,714 3,600 6,517 4,622,806 517,993 310,954 (a) (554,132) 11,116 1,716 76,698 52 46,995 6,085 22,700 $ 19,545 33,423 161 -

As a result of the exchange, Pioneer will no longer incur interest expense of approximately $12 million per year associated with the Preferred Shares. 21 41,773,238 9,182,795 11,229,303 11,370,165 22 PIONEER NATURAL RESOURCES COMPANY NOTES TO UNAUDITED PRO FORMA COMBINED FINANCIAL STATEMENTS SEPTEMBER 30, 1997 AND DECEMBER 31, 1996 (j) To reduce interest expense for (i) the amortization of the premiums (utilizing the effective interest rate method) recorded as part of purchase accounting for Mesa's 10-5/8% senior subordinated notes and 11-5/8% senior subordinated discount notes and (ii) the application of Pioneer's excess cash in 1996 to the reduction of Mesa's outstanding bank indebtedness at Mesa's 1996 pro forma incremental borrowing interest rate of 7% (see pro forma entry (k) below). (k) To adjust interest expense resulting from the borrowing of the funds necessary for Mesa's acquisition of Greenhill. Mesa's 1997 and 1996 pro forma incremental borrowing interest rate of 7% was utilized to determine the additional pro forma interest expense. (l) To eliminate the preferred stock dividends associated with Mesa's Series A and Series B Preferred Stock. (m) To adjust the weighted average shares outstanding for the acquisition of Mesa. This adjustment also assumes the conversion of Mesa's outstanding employee stock options into Pioneer employee stock options for purposes of computing weighted average shares outstanding. (n) To adjust interest expense resulting from the application of that portion of the sales proceeds from the Australasian Assets Sold and the 1996 Assets Sold necessary to retire Pioneer's outstanding bank indebtedness. The proceeds applied to retire Pioneer's outstanding bank indebtedness of $225 million resulted in a reduction in interest expense of $4.3 million. The reduction in interest expense was calculated utilizing Pioneer's weighted average rate on its bank indebtedness of 6.22% for the period during 1996 in which Pioneer had outstanding bank indebtedness. (o) To reduce interest expense as a result of the Recapitalization. Interest expense adjustments include the following for the year ended December 31, 1996: Pro Forma Historical --------- Pro Forma ---------- Adjustment ----------- Interest expense on former debt repaid in the Recapitalization: Secured notes Former credit agreement 12-3/4% secured discount notes 13-1/2% subordinated notes $ Interest expense on former debt repaid prior to the Recapitalization: 12-3/4% unsecured discount notes Interest expense on new debt issued in the Recapitalization: 10-5/8% senior subordinated notes 11-5/8% senior discount notes New Credit Facility Other interest expense ---------------------------$ 121,135 $ 86,605 $ (34,530) ========= ========== =========== 22 26,231 2,472 43,979 654 2,595 17,613 8,893 15,094 3,604 $ - 2,595 35,418 18,661 26,327 3,604 $ (26,231) (2,472) (43,979) (654) - 17,805 9,768 11,233 - 23 PIONEER NATURAL RESOURCES COMPANY NOTES TO UNAUDITED PRO FORMA COMBINED FINANCIAL STATEMENTS SEPTEMBER 30, 1997 AND DECEMBER 31, 1996 Other interest expense is primarily the interest portion of the administrative fee charged by Colorado Interstate Gas Company in connection with Mesa's West Panhandle field operations. The interest rate on the New Credit Facility is approximately 7.75% on the first $250 million due to an interest rate swap with the balance at a floating rate that during the period outstanding was approximately 7%. (p) To record the pro forma adjustment for an 8% annual dividend on the Mesa Series A and Series B Preferred Stock payable quarterly in additional shares of Mesa Series A and Series B Preferred Stock for at least the first four years after issuance as if the Mesa Series A and Series B Preferred Stock had been issued on January 1, 1996. NOTE 5. INCOME TAXES Pioneer will account for income taxes in accordance with the provisions of Statement of Financial Accounting Standards No. 109, "Accounting for Income Taxes." In accordance with SFAS 109, Pioneer will prepare separate tax calculations for each tax jurisdiction in which Pioneer will be subject to income taxes. NOTE 6. INCOME FROM CONTINUING OPERATIONS PER SHARE Income from continuing operations per share is computed based on the weighted average number of shares of common stock and common stock equivalents, if more than 3% dilutive, outstanding during the period. Fully diluted income from continuing operations per share is not presented since dilution is less than 3% on a pro forma combined basis. Income from continuing operations per share reflects the exchange of Chauvco Common Shares for Pioneer common stock or Exchangeable Shares, the exchange of Pioneer's Preferred Shares and the conversion of Mesa's Series A Preferred Stock and Mesa's Series B Preferred Stock to Pioneer common stock. NOTE 7. GENERAL AND ADMINISTRATIVE EXPENSE REDUCTIONS Mesa's general and administrative expenses for the year ended December 31, 1996 includes $9.4 million associated with the elimination of 86 positions from the total of 385 at December 31, 1995, and a significant downsizing of Mesa's natural gas vehicle equipment business in conjunction with the Recapitalization. Given the first quarter 1997 general and administrative expenses of $3.8 million, Mesa's continuing costs are estimated at approximately $15 million per year ($3.8 million multiplied by four quarters). In addition, Greenhill's general and administrative expenses prior to its sale to Mesa on April 15, 1997 of $13.3 million included severance costs paid to Greenhill employees of approximately $11 million as few of Greenhill's administrative personnel were retained. The accompanying Pro Forma Combined Statements of Operations for Pioneer do not include any adjustments related to the expected level of ongoing general and administrative expense. 23 24 PIONEER NATURAL RESOURCES COMPANY NOTES TO UNAUDITED PRO FORMA COMBINED FINANCIAL STATEMENTS SEPTEMBER 30, 1997 AND DECEMBER 31, 1996 NOTE 8. OIL AND GAS RESERVE DATA The following unaudited pro forma supplemental information regarding the oil and gas activities of Pioneer is presented pursuant to the disclosure requirements promulgated by the SEC and Statement of Financial Accounting Standards No. 69, "Disclosures About Oil and Gas Producing Activities." The pro forma reserve information is presented as if the sale of the Australasian Assets and 1996 Assets Sold and the acquisition of Chauvco, Mesa and Greenhill had occurred on January 1, 1996. Management emphasizes that reserve estimates are inherently imprecise and subject to revision and that estimates of new discoveries are more imprecise than those of producing oil and gas properties. Accordingly, the estimates are expected to change as future information becomes available; such changes could be significant. Quantities of oil and gas reserves Set forth below is a pro forma summary of the changes in the net quantities of oil and natural gas reserves for the year ended December 31, 1996.

Future income taxes are calculated by comparing discounted future cash flows to the tax basis of oil and gas properties, plus available carryforwards and credits, and applying the current tax rate to the difference. 24 136,264 2,442,990 (5,180) 26,206 - 11,494 3,320 (12,500) 121,904 38,059 (190,049) 2,328,700 25 PIONEER NATURAL RESOURCES COMPANY NOTES TO UNAUDITED PRO FORMA COMBINED FINANCIAL STATEMENTS SEPTEMBER 30, 1997 AND DECEMBER 31, 1996 December 31, 1996 ------------------------------------------------------------USA Argentina Canada Total --------------- ----------------------------------(in thousands) Oil and gas producing activities: Future cash inflows Future production costs Future development costs Future income tax expense -----------------------------6,948,109 429,724 339,841 10% annual discount factor -----------------------------Standardized measure of discounted future net cash flows ============ ========== ========== $ 13,987,546 (3,970,522) (389,701) (2,679,214) -----------7,717,674 (3,240,886) ------------ $ 3,707,223 ============ $ 599,243 (144,714) (24,084) (721) (214,813) $ 214,911 $ $ 680,112 (173,033) (10,632) (156,606) $ 15,266,901 (4,288,269) (424,417) (2,836,541) (114,840) (3,570,539) 225,001 $ 4,147,135 Changes relating to the standardized measure of discounted future net cash flows The principal sources of the change in the pro forma combined standardized measure of discounted future net cash flows for the year ended December 31, 1996 are as follows (in thousands): Oil and gas sales, net of production costs Net changes in prices and production costs Extensions and discoveries Purchases of minerals-in-place Revisions of estimated future development costs Revisions of previous quantity estimates Accretion of discount Changes in production rates, timing and other ----------Change in present value of future net revenues Net change in present value of future income taxes ----------1,487,867 Balance, beginning of year ----------Balance, end of year =========== 25 $ (651,480) 2,220,041 131,526 20,606 (71,763) 327,004 290,618 (150,096) 2,116,456 (628,589) 2,659,268 $ 4,147,134 26 PIONEER NATURAL RESOURCES COMPANY EXHIBIT 2.1 Combination Agreement, dated as of September 3, 1997, between Pioneer and Chauvco Resources Ltd.

In the event that a holder of Chauvco Common Shares has failed to validly make an election under Section 2.1(g) in the Letter of Transmittal and Election Form pursuant to this paragraph, such holder shall 7 -7be deemed to have elected the option under Section 2.1(g)(i).

(a) Chauvco determined that the fair market value of the Gabon Securities on September 3, 1997 was approximately US$60,000,000 relying on (i) the bidding process in connection with the sale of Chauvco, (ii) the reserve and evaluation reports prepared by Chauvco's independent engineers, (iii) the review and recommendation of Chauvco's senior management which established a range of values at various discount factors and an assessment of the exploration and development potential of the applicable properties, and (iv) an independent review conducted to confirm and support the allocation to the CRI Shares by Chauvco of a portion of the consideration received by the Chauvco Shareholders.

In the event of the exercise of the Liquidation Call Right by US Co, each holder shall be obligated to sell all the Exchangeable Shares held by the holder to US Co on the Liquidation Date on payment by US Co to the holder of the Liquidation Call Purchase Price for each such share. (b) To exercise the Liquidation Call Right, US Co must notify US Co Sub's Transfer Agent in writing, as agent for the holders of Exchangeable Shares, and US Co Sub of US Co's intention to exercise such right at least 55 days before the Liquidation Date in the case of a voluntary liquidation, dissolution or winding-up of US Co Sub and at least five Business Days before the 12 -12Liquidation Date in the case of an involuntary liquidation, dissolution or winding-up of US Co Sub. The Transfer Agent will notify the holders of Exchangeable Shares as to whether or not US Co has exercised the Liquidation Call Right forthwith after the expiry of the date by which the same may be exercised by US Co. If US Co exercises the Liquidation Call Right, on the Liquidation Date US Co will purchase and the holders will sell all of the Exchangeable Shares then outstanding for a price per share equal to the Liquidation Call Purchase Price. (c) For the purposes of completing the purchase of the Exchangeable Shares pursuant to the Liquidation Call Right, US Co shall deposit with the Transfer Agent, on or before the Liquidation Date, the Exchangeable Share Consideration representing the total Liquidation Call Purchase Price. Provided that such Exchangeable Share Consideration has been so deposited with the Transfer Agent, on and after the Liquidation Date the rights of each holder of Exchangeable Shares will be limited to receiving such holder's proportionate part of the total Liquidation Call Purchase Price payable by US Co without interest upon presentation and surrender by the holder of certificates representing the Exchangeable Shares held by such holder and the holder shall on and after the Liquidation Date be considered and deemed for all purposes to be the holder of the US Co Common Stock delivered to such holder.

If US Co does not exercise the Liquidation Call Right in the manner described above, on the Liquidation Date the holders of the Exchangeable Shares will be entitled to receive in exchange therefor the liquidation price otherwise payable by US Co Sub in connection with the liquidation, dissolution or winding-up of US Co Sub pursuant to Article 5 of the Exchangeable Share Provisions. Notwithstanding the foregoing, until such Exchangeable Share Consideration is delivered to the holder, the holder shall be deemed to still be a holder of Exchangeable Shares for purposes of all voting rights with respect thereto under the Voting and Exchange Trust Agreement. 5.2 US Co Redemption Call Right. (a) US Co shall have the overriding right (the "Redemption Call Right"), notwithstanding the proposed redemption of the Exchangeable Shares by US Co Sub pursuant to Article 7 of the Exchangeable Share Provisions, to purchase from all but not less than all of the holders (other than US Co or any Subsidiary thereof) of Exchangeable Shares on the Automatic Redemption Date all but not less than all of the Exchangeable Shares held by each such holder on payment by US Co to the holder of the Exchangeable Share Price applicable on the last Business Day prior to the Automatic Redemption Date (the "Redemption Call Purchase Price"). In the event of the exercise of the Redemption Call Right by US Co, each holder shall be obligated to sell all the Exchangeable Shares held by the holder to US Co on the Automatic Redemption Date on payment by US Co to the holder of the Redemption Call Purchase Price for each such share. (b) To exercise the Redemption Call Right, US Co must notify the Transfer Agent in writing, as agent for the holders of Exchangeable Shares, and US Co Sub of US Co's intention to exercise such right at least 125 days before the Automatic Redemption Date. The Transfer Agent will notify the holders of the Exchangeable Shares as to whether or not US Co has exercised the 13 -13Redemption Call Right forthwith after the date by which the same may be exercised by US Co. If US Co exercises the Redemption Call Right, on the Automatic Redemption Date US Co will purchase and the holders will sell all of the Exchangeable Shares then outstanding for a price per share equal to the Redemption Call Purchase Price. (c) For the purposes of completing the purchase of the Exchangeable Shares pursuant to the Redemption Call Right, US Co shall deposit with the Transfer Agent, on or before the Automatic Redemption Date, the Exchangeable Share Consideration representing the total Redemption Call Purchase Price. Provided that such Exchangeable Share Consideration has been so deposited with the Transfer Agent, on and after the Automatic Redemption Date the rights of each holder of Exchangeable Shares will be limited to receiving such holder's proportionate part of the total Redemption Call Purchase Price payable by US Co without interest upon presentation and surrender by the holder of certificates representing the Exchangeable Shares held by such holder and the holder shall on and after the Automatic Redemption Date be considered and deemed for all purposes to be the holder of the US Co Common Stock delivered to such holder. Upon surrender to the Transfer Agent of a certificate or certificates representing Exchangeable Shares, together with such other documents and instruments as may be required to effect a transfer of Exchangeable Shares under applicable law and such additional documents and instruments as the Transfer Agent may reasonably require, the holder of such surrendered certificate or certificates shall be entitled to receive in exchange therefor, and the Transfer Agent on behalf of US Co shall deliver to such holder, the Exchangeable Share Consideration to which the holder is entitled. If US Co does not exercise the Redemption Call Right in the manner described above, on the Automatic Redemption Date the holders of the Exchangeable Shares will be entitled to receive in exchange therefor the redemption price otherwise payable by US Co Sub in connection with the redemption of the Exchangeable Shares pursuant to Article 7 of the Exchangeable Share Provisions.

If only a part of the Exchangeable Shares represented by any certificate or certificates delivered to the Trustee are to be purchased by US Co under the Exchange Right, a new certificate for the balance of such Exchangeable Shares shall be issued to the Holder at the expense of US Co Sub. (f) Delivery of Exchangeable Share Consideration; Effect of Exercise. Promptly after receipt of the certificates representing the Exchangeable Shares which the Holder desires US Co to purchase under the Exchange Right (together with such documents and instruments of transfer and a duly completed form of notice of exercise of the Exchange Right), duly endorsed for transfer to US Co the Trustee shall notify US Co and US Co Sub of its receipt of the same, which notice to US Co and US Co Sub shall constitute exercise of the Exchange Right by the Trustee on behalf of the Holder of such Exchangeable Shares, and US Co shall immediately thereafter deliver or cause to be delivered to the Trustee, for delivery to the Holder of such Exchangeable Shares (or to such other persons, if any, properly designated by such Holder), the Exchangeable Share Consideration deliverable in connection with the exercise of the Exchange Right; provided, however, that no such delivery shall be made unless and until the Holder requesting the same shall have paid (or provided evidence satisfactory to the Trustee, US Co Sub and US Co of the payment of) the taxes (if any) payable as contemplated by Section 5(h) of this Agreement. Immediately upon 13 - 13 the giving of notice by the Trustee to US Co and US Co Sub of the exercise of the Exchange Right, as provided in this Section 5(f), the closing of the transaction of purchase and sale contemplated by the Exchange Right shall be deemed to have occurred, and the Holder of such Exchangeable Shares shall be deemed to have transferred to US Co all of its right, title and interest in and to such Exchangeable Shares and in the related interest in the Trust Estate and shall cease to be a holder of such Exchangeable Shares and shall not be entitled to exercise any of the rights of a holder in respect thereof, other than the right to receive his proportionate part of the total purchase price therefor, unless such Exchangeable Share Consideration is not delivered by US Co to the Trustee, for delivery to such Holder (or to such other persons, if any, properly designated by such Holder), within three Business Days of the date of the giving of such notice by the Trustee, in which case the rights of the Holder shall remain unaffected until such Exchangeable Share Consideration is delivered by US Co and any cheque included therein is paid. Concurrently with such Holder ceasing to be a holder of Exchangeable Shares, the Holder shall be considered and deemed for all purposes to be the holder of the shares of US Co Common Stock delivered to it pursuant to the Exchange Right. (g) Exercise of Exchange Right Subsequent to Retraction. In the event that a Holder has exercised its right under Article 6 of the Exchangeable Share Provisions to require US Co Sub to redeem any or all of the Exchangeable Shares held by the Holder (the "Retracted Shares") and is notified by US Co Sub pursuant to Section 6.6 of the Exchangeable Share Provisions that US Co Sub will not be permitted as a result of liquidity or solvency requirements of applicable law to redeem all such Retracted Shares, subject to receipt by the Trustee of written notice to that effect from US Co Sub and provided that US Co shall not have exercised the Retraction Call Right with respect to the Retracted Shares and that the Holder has not revoked the retraction request delivered by the Holder to US Co Sub pursuant to Section 6.1 of the Exchangeable Share Provisions, the retraction request will constitute and will be deemed to constitute notice from the Holder to the Trustee instructing the Trustee to exercise the Exchange Right with respect to those Retracted Shares which US Co Sub is unable to redeem. In any such event, US Co Sub hereby agrees with the Trustee and in favour of the Holder immediately to notify the Trustee of such prohibition against US Co Sub redeeming all of the Retracted Shares and immediately to forward or cause to be forwarded to the Trustee all relevant materials delivered by the Holder to US Co Sub or to the transfer agent of the Exchangeable Shares (including without limitation a copy of the retraction request delivered pursuant to Section 6.1 of the Exchangeable Share Provisions) in connection with such proposed redemption of the Retracted Shares and the Trustee will thereupon exercise the Exchange Right with respect to the Retracted Shares that US Co Sub is not permitted to redeem and will require US Co to purchase such shares in accordance with the provisions of this Article 5. (h) Stamp or Other Transfer Taxes. Upon any sale of Exchangeable Shares to US Co pursuant to the Exchange Right or the Automatic Exchange Rights, the share certificate or certificates representing US Co Common Stock to be delivered in connection with the payment of the total purchase price therefor shall be issued in the 14 - 14 name of the Holder of the Exchangeable Shares so sold or in such names as such Holder may otherwise direct in writing without charge to the holder of the Exchangeable Shares so sold, provided, however, that such Holder (i) shall pay (and neither US Co, US Co Sub nor the Trustee shall be required to pay) any documentary, stamp, transfer or other similar taxes that may be payable in respect of any transfer involved in the issuance or delivery of such shares to a person other than such Holder or (ii) shall have established to the satisfaction of the Trustee, US Co and US Co Sub that such taxes, if any, have been paid. (i) Notice of Insolvency Event. Immediately upon the occurrence of an Insolvency Event or any event which with the giving of notice or the passage of time or both would be an Insolvency Event US Co Sub and US Co shall give written notice thereof to the Trustee. As soon as practicable after receiving notice from US Co Sub and US Co or from any other Person of the occurrence of an Insolvency Event, the Trustee will mail to each Holder, at the expense of US Co, a notice of such Insolvency Event in the form provided by US Co, which notice shall contain a brief statement of the right of the Holders with respect to the Exchange Right. (j) Qualification of US Co Common Stock. US Co covenants that if any shares of US Co Common Stock to be issued and delivered pursuant to the Exchange Right or the Automatic Exchange Rights require registration or qualification with or approval of or the filing of document including any prospectus or similar document or the taking of any proceeding with or the obtaining of any order, ruling or consent from any governmental or regulatory authority under any Canadian or United States federal, provincial or state law or regulation or pursuant to the rules and regulations of any regulatory authority or the fulfillment of any other legal requirement (collectively, the "Applicable Laws") before such shares may be issued and delivered by US Co to the initial holder thereof (other than US Co Sub) or in order that such shares may be freely traded thereafter (other than any restrictions on transfer by reason of a holder being a "control person" of US Co for purposes of Canadian federal or provincial securities law or an "affiliate" of US Co or, prior to the date hereof, of Chauvco for purposes of United States federal or state securities law), US Co will in good faith expeditiously take all such actions and do all such things as are necessary to cause such shares of US Co Common Stock to be and remain duly registered, qualified or approved. US Co represents and warrants that it has in good faith taken all actions and done all things as are necessary under Applicable Laws as they exist on the date hereof to cause the shares of US Co Common Stock to be issued and delivered pursuant to the Exchange Right and the Automatic Exchange Rights and to be freely tradeable thereafter (other than restrictions on transfer by reason of a holder being a "control person" of US Co for the purposes of Canadian federal and provincial securities law or an "affiliate" of US Co or, prior to the date hereof, of Chauvco for the purposes of United States federal or state securities law). US Co will in good faith expeditiously take all such actions and do all such things as are necessary to cause all shares of US Co Common Stock to be delivered pursuant to the Exchange Right or the Automatic Exchange Rights to be listed, quoted or posted for trading on all stock exchanges and quotation systems on which such shares are listed, quoted or posted for trading at such time. 15 - 15 - (k) Reservation of Shares of US Co Common Stock. US Co hereby represents, warrants and covenants that it has irrevocably reserved for issuance and will at all times keep available, free from pre-emptive and other rights, out of its authorized and unissued capital stock such number of shares of US Co Common Stock (i) as is equal to the sum of (A) the number of Exchangeable Shares issued and outstanding from time to time and (B) the number of Exchangeable Shares issuable upon the exercise of all rights to acquire Exchangeable Shares outstanding from time to time and (ii) as are now and may hereafter be required to enable and permit US Co Sub and US Co to meet their respective obligations hereunder, under the Support Agreement, under the Exchangeable Share Provisions and under any other security or commitment pursuant to the Arrangement with respect to which US Co may now or hereafter be required to issue shares of US Co Common Stock. (l) Automatic Exchange on Liquidation of US Co. (i) US Co will give the Trustee written notice of each of the following events at the time set forth below: (A) in the event of any determination by the board of directors of US Co to institute voluntary liquidation, dissolution or winding-up proceedings with respect to US Co or to effect any other distribution of assets of US Co among its stockholders for the purpose of winding-up its affairs, at least 60 days prior to the proposed effective date of such liquidation, dissolution, winding-up or other distribution; and (B) immediately, upon the earlier of (I) receipt by US Co of notice of and (II) US Co otherwise becoming aware of any threatened or instituted claim, suit, petition or other proceedings with respect to the involuntary liquidation, dissolution or winding-up of US Co or to effect any other distribution of assets of US Co among its stockholders for the purpose of winding-up its affairs. (ii) Immediately following receipt by the Trustee from US Co of notice of any event (a "Liquidation Event") contemplated by Section 5(l)(i) above, the Trustee will give notice thereof to the Holders. Such notice will be provided by US Co to the Trustee and shall include a brief description of the automatic exchange of Exchangeable Shares for shares of US Co Common Stock provided for in Section 5(l)(iii) below. (iii) In order that the Holders will be able to participate on a PRO RATA basis with the holders of US Co Common Stock in the distribution of assets of US Co in connection with a Liquidation Event, immediately prior to the effective time (the "Liquidation Event Effective Time") of a Liquidation Event all of the then outstanding Exchangeable Shares shall be automatically exchanged for shares of US Co Common Stock. To effect such automatic exchange, US 16 - 16 Co shall be deemed to have purchased each Exchangeable Share outstanding immediately prior to the Liquidation Event Effective Time and held by Holders, and each Holder shall be deemed to have sold the Exchangeable Shares held by it at such time, for a purchase price per share equal to the Exchangeable Share Price applicable at such time. In connection with such automatic exchange, US Co will provide to the Trustee an Officers' Certificate setting forth the calculation of the purchase price for each Exchangeable Share. (iv) The closing of the transaction of purchase and sale contemplated by Section 5(l)(iii) above shall be deemed to have occurred immediately prior to the Liquidation Event Effective Time, and each Holder of Exchangeable Shares shall be deemed to have transferred to US Co all of the Holder's right, title and interest in and to such Exchangeable Shares and the related interest in the Trust Estate and shall cease to be a holder of such Exchangeable Shares and US Co shall deliver to the Holder the Exchangeable Share Consideration deliverable upon the automatic exchange of Exchangeable Shares. Concurrently with such Holder ceasing to be a holder of Exchangeable Shares, the Holder shall be considered and deemed for all purposes to be the holder of the shares of US Co Common Stock issued to it pursuant to the automatic exchange of Exchangeable Shares for US Co Common Stock and the certificates held by the Holder previously representing the Exchangeable Shares exchanged by the Holder with US Co pursuant to such automatic exchange shall thereafter be deemed to represent the shares of US Co Common Stock issued to the Holder by US Co pursuant to such automatic exchange. Upon the request of a Holder and the surrender by the Holder of Exchangeable Share certificates deemed to represent shares of US Co Common Stock, duly endorsed in blank and accompanied by such instruments of transfer as US Co may reasonably require, US Co shall deliver or cause to be delivered to the Holder certificates representing the shares of US Co Common Stock of which the Holder is the holder. 6. RESTRICTIONS ON ISSUANCE OF US CO SPECIAL VOTING STOCK During the term of this Agreement, US Co will not issue any shares of US Co Special Voting Stock in addition to the Voting Share. 7. CONCERNING THE TRUSTEE (a) Powers and Duties of the Trustee.

In the exercise of such rights, powers and authorities the Trustee shall have (and is granted) such incidental and additional rights, powers and authority not in conflict with any of the provisions of this Agreement as the Trustee, acting in good faith and in the reasonable exercise of its discretion, may deem necessary, appropriate or desirable to effect the purpose of the Trust. Any exercise of such discretionary rights, powers and authorities by the Trustee shall be final, conclusive and binding upon all persons. For greater certainty, the Trustee shall have only those duties as are set out specifically in this Agreement. The Trustee in exercising its rights, powers, duties and authorities hereunder shall act honestly and in good faith with a view to the best interests of the Holders and shall exercise the care, diligence and skill that a reasonably prudent trustee would exercise in comparable circumstances. The Trustee shall not be bound to give any notice or do or take any act, action or proceeding by virtue of the powers conferred on it hereby unless and until it shall be specifically required to do so under the terms hereof; nor shall the Trustee be required to take any notice of, or to do or to take any act, action or proceeding as a result of any default or breach of any provision hereunder, unless and until notified in writing of such default or breach, which notices shall distinctly specify the default or breach desired to be brought to the attention of the Trustee and in the absence of such notice 18 - 18 the Trustee may for all purposes of this Agreement conclusively assume that no default or breach has been made in the observance or performance of any of the representations, warranties, covenants, agreements or conditions contained herein. (b) No Conflict of Interest. The Trustee represents to US Co Sub and US Co that at the date of execution and delivery of this Agreement there exists no material conflict of interest in the role of the Trustee as a fiduciary hereunder and the role of the Trustee in any other capacity. The Trustee shall, within 90 days after it becomes aware that such a material conflict of interest exists, either eliminate such material conflict of interest or resign in the manner and with the effect specified in Article 10 hereof. If, notwithstanding the foregoing provisions of this Section 7(b), the Trustee has such a material conflict of interest, the validity and enforceability of this Agreement shall not be affected in any manner whatsoever by reason only of the existence of such material conflict of interest. If the Trustee contravenes the foregoing provisions of this Section 7(b), any interested party may apply to the Alberta Court of Queen's Bench for an order that the Trustee be replaced as trustee hereunder. (c) Dealings with Transfer Agents, Registrars, etc. US Co Sub and US Co irrevocably authorize the Trustee, from time to time, to: (i) consult, communicate and otherwise deal with the respective registrars and transfer agents, and with any such subsequent registrar or transfer agent, of the Exchangeable Shares and US Co Common Stock; and (ii) requisition, from time to time, (A) from any such registrar or transfer agent any information readily available from the records maintained by it which the Trustee may reasonably require for the discharge of its duties and responsibilities under this Agreement and (B) from the transfer agent of US Co Common Stock, and any subsequent transfer agent of such shares, the share certificates issuable upon the exercise from time to time of the Exchange Right and pursuant to the Automatic Exchange Rights in the manner specified in Article 5 hereof. US Co Sub and US Co irrevocably authorize their respective registrars and transfer agents to comply with all such requests. US Co covenants that it will supply its transfer agent with duly executed share certificates for the purpose of completing the exercise from time to time of the Exchange Right and the Automatic Exchange Rights, in each case pursuant to Article 5 hereof. (d) Books and Records. The Trustee shall keep available for inspection by US Co and US Co Sub, at the Trustee's principal office in Calgary, Alberta, correct and complete books and records of account relating to the Trustee's actions under this Agreement, including without limitation all information relating to mailings and instructions to and from Holders and all transactions pursuant to the Voting Rights, the Exchange Right and the Automatic Exchange Rights for the term of this Agreement.

(e) Income Tax Returns and Reports. The Trustee shall, to the extent necessary, prepare and file on behalf of the Trust appropriate United States and Canadian income tax returns and any other returns or reports as may be required by applicable law or pursuant to the rules and regulations of any securities exchange or other trading system through which the Exchangeable Shares are traded and, in connection therewith, may obtain the advice and assistance of such experts as the Trustee may consider necessary or advisable. If requested by the Trustee, US Co shall retain such experts for purposes of providing such advice and assistance. (f) Indemnification Prior to Certain Actions by Trustee. The Trustee shall exercise any or all of the rights, duties, powers or authorities vested in it by this Agreement at the request, order or direction of any Holder upon such Holder furnishing to the Trustee reasonable funding, security and indemnity against the costs, expenses and liabilities which may be incurred by the Trustee therein or thereby, provided that no Holder shall be obligated to furnish to the Trustee any such funding, security or indemnity in connection with the exercise by the Trustee of any of its rights, duties, powers and authorities with respect to the Voting Share pursuant to Article 4 hereof, subject to Section 7(o) hereof, and with respect to the Exchange Right pursuant to Article 5 hereof, subject to Section 7(o) hereof, and with respect to the Automatic Exchange Rights pursuant to Article 5 hereof. None of the provisions contained in this Agreement shall require the Trustee to expend or risk its own funds or otherwise incur financial liability in the exercise of any of its rights, powers, duties or authorities unless funded, given funds, security and indemnified as aforesaid. (g) Actions by Holders. No Holder shall have the right to institute any action, suit or proceeding or to exercise any other remedy authorized by this Agreement for the purpose of enforcing any of its rights or for the execution of any trust or power hereunder unless the Holder has requested the Trustee to take or institute such action, suit or proceeding and furnished the Trustee with the funding, security and indemnity referred to in Section 7(f) hereof and the Trustee shall have failed to act within a reasonable time thereafter. In such case, but not otherwise, the Holder shall be 20 - 20 entitled to take proceedings in any court of competent jurisdiction such as the Trustee might have taken; it being understood and intended that no one or more Holders shall have any right in any manner whatsoever to affect, disturb or prejudice the rights hereby created by any such action, or to enforce any right hereunder or under the Voting Rights, the Exchange Right or the Automatic Exchange Rights, except subject to the conditions and in the manner herein provided, and that all powers and trusts hereunder shall be exercised and all proceedings at law shall be instituted, had and maintained by the Trustee, except only as herein provided, and in any event for the equal benefit of all Holders. (h) Reliance upon Declarations. The Trustee shall not be considered to be in contravention of any of its rights, powers, duties and authorities hereunder if, when required, it acts and relies in good faith upon lists, mailing labels, notices, statutory declarations, certificates, opinions, reports or other papers or documents furnished pursuant to the provisions hereof or required by the Trustee to be furnished to it in the exercise of its rights, powers, duties and authorities hereunder and such lists, mailing labels, notices, statutory declarations, certificates, opinions, reports or other papers or documents comply with the provisions of Section 7(i) hereof, if applicable, and with any other applicable provisions of this Agreement.

INDEMNIFICATION AND LIMITATION OF LIABILITY (a) Indemnification of the Trustee. US Co and US Co Sub jointly and severally agree to indemnify and hold harmless the Trustee and each of its directors, officers, employees and agents appointed and acting in accordance with this Agreement (collectively, the "Indemnified Parties") against all claims, losses, damages, costs, penalties, fines and reasonable expenses (including reasonable expenses of the Trustee's legal counsel on a solicitor and his own client basis) which, without fraud, negligence, willful misconduct or bad faith on the part of such Indemnified Party, may be paid, incurred or suffered by the Indemnified Party by reason of or as a result of the Trustee's acceptance or administration of the Trust, its compliance with its duties set forth in this Agreement, or any written or oral instructions delivered to the Trustee by US Co or US Co Sub pursuant hereto. In no case shall US Co or US Co Sub be liable under this indemnity for any claim against any of the Indemnified Parties unless US Co and US Co Sub shall be notified by the Trustee of the written assertion of a claim or of any action commenced against the Indemnified Parties, promptly after any of the Indemnified Parties shall have received any such written assertion of a claim or shall have been served with a summons or other first legal 24 - 24 process giving information as to the nature and basis of the claim. Subject to (ii), below, US Co and US Co Sub shall be entitled to participate at their own expense in the defense and, if US Co or US Co Sub so elect at any time after receipt of such notice, either of them may assume the defense of any suit brought to enforce any such claim. The Trustee shall have the right to employ separate counsel in any such suit and participate in the defense thereof but the fees and expenses of such counsel shall be at the expense of the Trustee unless: (i) the employment of such counsel has been authorized by US Co or US Co Sub, such authorization not to be unreasonably withheld; or (ii) the named parties to any such suit include both the Trustee and US Co or US Co Sub and the Trustee shall have been advised by counsel acceptable to US Co or US Co Sub that there may be one or more legal defenses available to the Trustee that are different from or in addition to those available to US Co or US Co Sub and that an actual or potential conflict exists (in which case US Co and US Co Sub shall not have the right to assume the defense of such suit on behalf of the Trustee but shall be liable to pay the reasonable fees and expenses of counsel for the Trustee). (b) Limitation of Liability. The Trustee shall not be held liable for any loss which may occur by reason of depreciation of the value of any part of the Trust Estate or any loss incurred on any investment of funds pursuant to this Agreement except to the extent that such loss is attributable to the fraud, negligence, willful misconduct or bad faith on the part of the Trustee. 10. CHANGE OF TRUSTEE (a) Resignation. The Trustee, or any trustee hereafter appointed, may at any time resign by giving written notice of such resignation to US Co and US Co Sub specifying the date on which it desires to resign, provided that such notice shall never be given less than 60 days before such desired resignation date unless US Co and US Co Sub otherwise agree and provided further that such resignation shall not take effect until the date of the appointment of a successor trustee and the acceptance of such appointment by the successor trustee.

The amount of principal owing on any Lender's Loan Note at any given time shall be the aggregate amount of all Revolving Loan Advances theretofore made by such Lender minus all payments of principal theretofore received by such Lender on such Loan Note. Interest on each Loan Note shall accrue and be due and payable as provided herein and therein. Section 2.2 Requests for Revolving Loan Advances. Borrower must give to Administrative Agent not later than 11:00 a.m., Dallas, Texas time, for same day funding, and not later than 1:00 p.m., Dallas, Texas time, for next Business Day funding, written notice, or telephonic notice promptly confirmed in writing, of any requested Revolving Loan Advances, after which Administrative Agent shall give each other Lender prompt notice thereof. Each such written request or confirmation must be made in the form and substance of Exhibit C attached hereto, duly completed (herein called a "Request for Advance"). Each such telephonic request shall be deemed a representation, warranty, acknowledgment and agreement by Borrower as to the matters which are required to be set out in such written confirmation. If all conditions precedent to a Revolving Loan Advance have been met, each Lender will on the date requested remit, not later than 1:00 p.m., Dallas, Texas time, for same day funding, and not later than 11:00 a.m., Dallas, Texas time, the following Business Day for next Business Day funding, to Administrative Agent at Administrative Agent's office in Dallas, Texas, or to such other office as Administrative Agent may specify from time to time by notice to Lenders, the amount of such Lender's Revolving Loan Advance in immediately available funds, and upon receipt of such funds, unless to its actual knowledge any conditions precedent to such Revolving Loan Advances have been neither met nor waived as provided herein, Administrative Agent shall promptly make the Revolving Loan Advances available to Borrower. Each Request for Advance shall be irrevocable and binding on Borrower. Unless Administrative Agent shall have received prompt notice from a Lender that such Lender will not make available to Administrative Agent such Lender's Revolving Loan Advance, Administrative Agent may in its discretion assume that such Lender has made such Revolving Loan Advance available to Administrative Agent in accordance with this Section and Administrative Agent may if it chooses, in reliance upon such assumption, make such Revolving Loan Advance available to Borrower. If and to the extent such Lender shall not so make its Revolving Loan Advance available to Administrative Agent, such Lender and Borrower severally agree to pay or repay to Administrative Agent on demand the amount of such Revolving Loan Advance together with interest thereon, for each day from the date such amount is made available to Borrower until the date such amount is paid or repaid to Administrative Agent, (i) if paid or repaid by Borrower at the interest rate applicable at the time to the other Revolving Loan Advances made on such date of such Revolving Loan Advance and (ii) if paid or repaid by such Lender, at the Federal Funds Rate. The failure of 21 26 any Lender to make any Revolving Loan Advance to be made by it hereunder shall not relieve any other Lender of its obligation hereunder, if any, to make its Revolving Loan Advance, but no Lender shall be responsible for the failure of any other Lender to make any Revolving Loan Advance to be made by such other Lender. Section 2.3 Rate Elections. Borrower may from time to time designate all or any portions of the Loans (including any yet to be made Revolving Loan Advances which are to be made prior to or at the beginning of the designated Eurodollar Interest Period but excluding any portions of the Loans which are required to be repaid prior to the end of the designated Eurodollar Interest Period and excluding any Competitive Bid Advance and any Swing Line Advance) as a "Tranche", which term refers to a set of Eurodollar Portions of the same type with identical Eurodollar Interest Periods and with each Lender participating in such Tranche in accordance with its Percentage Share. Without the consent of Required Lenders, Borrower may not make such election, and Administrative Agent and Lenders shall not be required to give effect to such election, during the continuance of a Default and Borrower may make such an election with respect to already existing Eurodollar Portions only if such election will take effect at or after the termination of the Eurodollar Interest Period applicable thereto. Each election by Borrower of a Tranche shall: (a) Be made in writing in the form and substance of Exhibit D attached hereto, duly completed, herein called a "Rate Election"; (b) Specify the aggregate amount of the Loans which Borrower desires to designate as such Tranche, the first day of the Eurodollar Interest Period which is to apply thereto, and the length of such Eurodollar Interest Period; and (c) Be received by Administrative Agent not later than 10:00 a.m., Dallas, Texas time, on the third Business Day preceding the first day of the specified Eurodollar Interest Period. Promptly after receiving any such Rate Election which meets the requirements of this Section, Administrative Agent shall notify each Lender thereof. Each Rate Election shall be irrevocable. Borrower may not make any Rate Election which does not specify an Eurodollar Interest Period complying with the definition of "Eurodollar Interest Period" in Section 1.1, and the aggregate amount of the Tranche elected in any Rate Election must be $10,000,000 or a higher integral multiple of $1,000,000. Upon the termination of each Eurodollar Interest Period the portion of each Loan within the related Tranche shall, unless the subject of a new Rate Election then taking effect, automatically become a part of the Base Rate Portion of such Loan and become subject to all provisions of the Loan Documents governing such Base Rate Portion. Borrower shall have no more than fifteen (15) Tranches in effect at any time. If requested to do so by Borrower through Administrative Agent at least two (2) 22 27 Business Days before the delivery date of any proposed Rate Election, each Lender will advise Administrative Agent before 10:00 a.m., Dallas, Texas time, on the Business Day following receipt of such request as to whether, if Borrower selects a specified duration of nine (9) or twelve (12) months for the Eurodollar Interest Period applicable to such proposed Rate Election, such Lender expects that deposits in dollars with a corresponding term will be available to it in the relevant market on the first day of such Eurodollar Interest Period in the amount required to fund the Eurodollar Portion of its Loan to which such Eurodollar Interest Period would apply. Unless a Lender responds by such time to the effect that it expects such deposits will be available to it, Borrower shall not be entitled to select such proposed duration for such Eurodollar Interest Period. Each Lender may, if it so elects, fulfill its obligation to fund any Eurodollar Portion by causing one of its foreign branches or Affiliates (or an international banking facility created by such Lender) to fund or continue such Eurodollar Portion; provided, however, that such Eurodollar Portion shall be deemed to have been made and held by such Lender, and the obligations of the subject Borrower to repay such Eurodollar Portion shall nevertheless be to such Lender for the account of such branch, or Affiliate (or international banking facility). In addition, Borrower hereby consents and agrees that, for purposes of any determination to be made for purposes of Sections 2.17, 2.18, 2.19 and 2.20, it shall be conclusively assumed that such Lender elected to fund all Eurodollar Portions by purchasing Dollar deposits in the interbank eurodollar market of its designated office. Section 2.4 Swing Line Advances. In addition to borrowings pursuant to Section 2.1(a) or Section 2.22, Borrower may request Swing Line Lender to make advances to Borrower on any Business Day (unless Borrower and Swing Line Lender agree otherwise) during the Loan Commitment Period as provided in Sections 2.5 and 2.6 (herein called "Swing Line Advances"); provided, however, that (a) at no time shall the outstanding aggregate principal amount of all Swing Line Advances under this Agreement plus all "Swing Line Advances" (as defined in the 364 Day Credit Facility), if any, outstanding under the 364 Day Credit Facility exceed $50,000,000, and (b) at no time shall the sum of (1) the outstanding aggregate principal amount of all Swing Line Advances to Borrower, (2) the outstanding aggregate principal amount of the Revolving Loans, (3) the outstanding aggregate principal amount of LC Obligations and (4) the outstanding aggregate principal amount of all Competitive Bid Advances, exceed the Facility Amount. Section 2.5 Procedure for Swing Line Advances. (a) No later than 11:00 a.m., Dallas, Texas time, on a Business Day on which Borrower desires a Swing Line Advance, Borrower shall transmit to Swing Line Lender and to Administrative Agent by telecopy a notice in substantially the form of Exhibit E attached hereto (herein called a "Request for Swing Line Loan"). Swing Line Lender will specify the rate of interest per annum which 23 28 will be the fixed rate of interest to be charged for such Swing Line Advance until maturity (herein called the "Swing Line Rate"). (b) Swing Line Lender shall wire the Swing Line Advance in immediately available funds by no later than 1:00 p.m., Dallas, Texas time on the date of request for Swing Line Advance, on such day to Administrative Agent, which shall deposit such funds to an account designated by Borrower by no later than 1:15 p.m. on the same day. (c) Borrower shall repay each such Swing Line Advance on or before 1:00 p.m., Dallas, Texas time, on the following Business Day or at such other maturity (such date of maturity being no more than fourteen (14) days after the date of the Swing Line Advance and no later than the Maturity Date) as is agreed to by Borrower, Administrative Agent and the Swing Line Lender. The repayment shall be paid on such date by Borrower (which payment may be in the form of a Swing Line Advance advanced to Borrower on that day) to Administrative Agent in immediately available funds with instructions to Administrative Agent to forward such proceeds to the Swing Line Lender. Any accrued and unpaid interest pursuant to Swing Line Advances shall be paid by Borrower (which payment may be in the form of a Swing Line Advance advanced to Borrower on that day) to Administrative Agent in immediately available funds on the first Business Day of each calendar month with instructions to Administrative Agent to forward such proceeds to the Swing Line Lender. (d) Interest on the Swing Line Advances shall be computed on the basis of a year of 365 or 366 days and actual days elapsed (including the first day, but excluding the last day) occurring in the period for which payable and shall not exceed Maximum Lawful Rate. Past due principal and interest (to the extent allowed by law) shall bear interest at the lesser of the Default Rate or the Maximum Lawful Rate and shall be payable on demand. (e) The Swing Line Advances made by the Swing Line Lender shall be evidenced by a single promissory note of Borrower payable to the order of the Swing Line Lender in the amount of $50,000,000 and in substantially the form of Exhibit A-2 attached hereto, with appropriate insertions (herein called a "Swing Line Note"). The date, amount, Swing Line Rate and maturity of each Swing Line Advance made by a Lender to Borrower, and each payment made on account of the principal thereof, shall be recorded by such Lender on its books. (f) The Swing Line Advances will be used by Borrower to provide working capital for the operations of Borrower and its Subsidiaries and for general business purposes. No Swing Line Advances shall be used for the purpose of purchasing 24 29 or carrying any Margin Stock in violation of the Margin Regulations. (g) The obligation of the Swing Line Lender to make each Swing Line Advance after timely acceptance by Borrower is further subject to the conditions contained in Article 3. Section 2.6 (a) Special Provisions for Swing Line Advances. Lenders to Make Revolving Loan Advances. (i) Swing Line Lender, at any time in its discretion, upon written request to Lenders through Administrative Agent (with a copy to Borrower), may require each Lender (including the Swing Line Lender) to make a Revolving Loan Advance, subject to the provisions of Section 2.1 hereof, in an amount equal to such Lender's Percentage Share of the outstanding Swing Line Advances. Swing Line Lender shall deliver such request to Administrative Agent prior to 11:00 a.m., Dallas, Texas time, on the Business Day next preceding the date (which shall be a Business Day) on which such Revolving Loan Advances are to be made. Promptly upon receipt of any such request, Administrative Agent shall give notice thereof to Lenders. Each Lender shall make available its Percentage Share of such Revolving Loans to Administrative Agent by 11:00 a.m., Dallas, Texas time, on the requested date for such Revolving Loan Advances. Administrative Agent shall apply the proceeds of such Revolving Loan Advances to prepay the Swing Line Advances of the Swing Line Lender; provided, however, that Administrative Agent shall be obligated to make the proceeds of such Revolving Loans available only to the extent received by it from Lenders. All Revolving Loans made pursuant to this subsection shall be Base Rate Loans. (ii) In the event Administrative Agent advances proceeds of any Revolving Loan to Swing Line Lender and one or more of the Lenders (other than Swing Line Lender) fail to fund all or any portion of such Revolving Loan Advance immediately upon receipt of notice from Administrative Agent, then (I) such Lender shall pay directly to Administrative Agent the amount thereof together with interest thereon at the Federal Funds Rate, and (II) if not paid by such Bank, the Swing Line Lender will repay directly to Administrative Agent such amount as will equal the amount such other Lender(s) failed to fund, together with interest at the Federal Funds Rate. (b) Participations in Swing Line Advances. (i) If, at any time prior to the making of Revolving Loans pursuant to subsection 2.6(a)(i) hereof, any Event of Default described in Sections 6.1(h) hereof shall have occurred, each Lender, on the date such Revolving Loan Advance was to have been made or, if no request for Revolving Loan Advances had been made 25 30 pursuant to Section 2.6(a)(i) hereof, promptly upon request by the Swing Line Lender delivered to Administrative Agent, shall purchase an undivided participation interest in all outstanding Swing Line Advances in an amount equal to its Percentage Share times the outstanding amount of such Swing Line Advances. Each Lender (other than the Swing Line Lender) will transfer immediately to Administrative Agent for credit to Swing Line Lender, in immediately available funds, the amount of its participation. Upon receipt thereof, the Swing Line Lender will deliver to such other Lender a Swing Line Advance Participation Certificate, dated the date of receipt of such funds and in the amount of such Lender's participation. (ii) Whenever, at any time after the Swing Line Lender has received from any other Lender such other Lender's participating interest in a Swing Line Advance, the Swing Line Lender receives any payment on account thereof, Administrative Agent will distribute to such other Lender its participating interest in such amount (appropriately adjusted, in the case of interest payments, to reflect the period of time during which such Lender's participating interest was outstanding and funded); provided, however, that in the event that any payment received by Swing Line Lender is required to be returned, such other Lender will return to Swing Line Lender any portion thereof previously distributed to it. (c) Acknowledged Privity. Borrower expressly agrees that, in respect of each Lender's funded participation interest in any Swing Line Advance, such Lender shall be deemed to be in privity of contract with Borrower and have the same rights and remedies against Borrower under the Loan Documents as if such funded participation interest in such Swing Line Advance were a Revolving Loan. (d) Unconditional Obligation. Each Lender's obligation to make Revolving Loan Advances or to purchase participation interests in Swing Line Advances as provided in this Section shall be absolute and unconditional and shall not be affected by any circumstance, including, without limitation, (A) any set-off, counterclaim, recoupment, defense or other right which such Lender may have against Swing Line Lender, Borrower or any other Person for any reason whatsoever, (B) the existence of any Default or Event of Default at any time, (C) the occurrence of any event or existence of any condition that might have a Material Adverse Effect, or (D) any other circumstance, happening or event whatsoever, whether or not similar to any of the foregoing. Section 2.7 Facility Fee; Amendment Fee. In consideration of each Lender's commitment to make Revolving Loan Advances and Competitive Bid Advances, Borrower will pay, or cause the payment, to Administrative Agent for the account of each Lender an annual facility fee payable to each Lender determined by applying the Facility Fee Rate to such Lender's Percentage Share of the Facility Amount as of the date of such payment, payable in arrears quarterly until the Maturity Date, with the first payment thereof to be January 1, 1998, 26 31 subsequent payments on the first day following each successive calendar quarter ending on each March, June, September and December, and the final payment thereof on the Maturity Date. Borrower will pay, or cause the payment, to Administrative Agent for the account of each Lender a non-refundable amendment fee payable to each Lender determined by applying the Amendment Fee Rate to such Lender's Percentage Share of the Facility Amount as of the Effective Date. Section 2.8 Managing Agents' Fees. In addition to all other amounts due to the Managing Agents under the Loan Documents, Borrower will pay the non-refundable annual fees set forth in those certain Fee Letters dated June 25, 1997. Section 2.9 Termination and Reduction of Commitments. (a) Unless previously terminated, the Commitments shall terminate on the Maturity Date. (b) Borrower may at any time terminate, or from time to time reduce, the Commitments; provided that (i) each reduction of the Commitments shall be in an amount that is an integral multiple of $1,000,000 and not less than $5,000,000 and (ii) Borrower shall not terminate or reduce the Commitments if, after giving effect to any concurrent prepayment of the Loans in accordance with Section 2.10, the sum of (i) all Lenders' Revolving Loan Advances (including any Revolving Loan Advances to be made but not yet made pursuant to a Request for Advance) outstanding at any time plus (ii) the LC Obligations of all Lenders at such time plus (iii) all Swing Line Advances to Borrower plus (iv) all Lenders' Competitive Bid Advances outstanding at such time, would exceed the total Commitments. (c) Borrower shall notify the Administrative Agent of any election to terminate or reduce the Commitments under paragraph (b) of this Section at least two Business Days prior to the effective date of such termination or reduction, specifying such election and the effective date thereof. Promptly following receipt of any notice, the Administrative Agent shall advise the Lenders of the contents thereof. Each notice delivered by Borrower pursuant to this Section shall be irrevocable; provided that a notice of termination of the Commitments delivered by Borrower may state that such notice is conditioned upon the effectiveness of other credit facilities, in which case such notice may be revoked by Borrower (by notice to the Administrative Agent on or prior to the specified effective date) if such condition is not satisfied. Any termination or reduction of the Commitments shall be permanent. Each reduction of the Commitments shall be made ratably among the Lenders in accordance with their respective Commitments. Section 2.10 Optional Prepayments. Borrower may, upon notice to each Lender identical to that required for related borrowings under this Agreement, from time to time and without premium or penalty, prepay its Notes, in whole or in part, so long as the aggregate 27 32 amounts of all partial prepayments of principal concurrently paid on such Notes equals $5,000,000 or any higher integral multiple of $1,000,000 or the aggregate outstanding balance of the Loans, and so long as Borrower does not prepay any Revolving Loan Advance, Competitive Bid Advance or Swing Line Advance except in accordance herewith. Any amounts prepaid pursuant to this Section shall be in addition to, and not in lieu of, all payments otherwise required to be paid under the Loan Documents at the time of such prepayment. Section 2.11 Payments to Lenders. Except as expressly set forth in Section 2.5(c) with respect to repayment of Swing Line Advances and Section 2.22(b) with respect to repayment of Competitive Bid Advances, Borrower will make each payment which it owes under the Loan Documents to Administrative Agent at its principal banking office in Dallas, Texas, or to such other office as Administrative Agent may specify from time to time by notice to Borrower for the account of each Lender to whom such payment is owed, without the application of any setoff, deduction or counterclaim. Each such payment must be received by Administrative Agent not later than 1:00 p.m., Dallas, Texas time, on the date such payment becomes due and payable, in lawful money of the United States of America and in immediately available funds. Any payment received by Administrative Agent after such time will be deemed to have been made on the next Business Day. Should any such payment become due and payable on a day other than a Business Day, the maturity of such payment shall be extended to the next succeeding Business Day (except, with respect to any Eurodollar Portion, as may be otherwise required by the definition of Eurodollar Interest Period), and, in the case of a payment of principal or past due interest, interest shall accrue and be payable thereon for the period of such extension as provided in the Loan Document under which such payment is due. All payments applied to principal or interest on any Note shall be applied first to any interest then due and payable, then to principal then due and payable, and last to any prepayment of principal and interest in compliance with Section 2.10. Unless otherwise expressly provided, all payments by any Designated Entity pursuant to this Agreement or any other Loan Document shall be made by such Designated Entity to Administrative Agent for account of Agents and Lenders pro rata among Obligations of the same type and, if applicable, having the same Eurodollar Interest Period or, in the case of Swing Line Advances or Competitive Bid Advances, the same maturity date. Section 2.12 Letters of Credit. Subject to the terms and conditions hereof, Borrower may request Issuing Bank to issue one or more Letters of Credit, provided that, after taking such Letter of Credit into account: (a) the sum of (1) the aggregate principal amount of Revolving Loans outstanding at such time, (2) the aggregate principal amount of LC Obligations outstanding at such time, (3) the aggregate principal amount of outstanding Swing Line Advances to Borrower and (4) the aggregate principal amount of outstanding 28 33 Competitive Bid Advances to Borrower, does not exceed the least of (i) the aggregate of all Lenders' Loan Commitments at such time or (ii) the Facility Amount; (b) the aggregate amount of LC Obligations outstanding at such time after giving effect to such request does not exceed $50,000,000; (c) the expiration date of such Letter of Credit is prior to the Maturity Date, unless otherwise agreed to by all of the Lenders and the Issuing Bank; (d) such Letter of Credit is to be used for general corporate purposes of Borrower or any of its Subsidiaries, subject to paragraph (e) of this Section; (e) the terms of such Letter of Credit are acceptable to Issuing Bank in the reasonable exercise of its discretion; and (f) all other conditions in this Agreement to the issuance of such Letter of Credit have been satisfied. Issuing Bank will honor any such request if the foregoing conditions (a) through (g) (herein called the "LC Conditions") have been met as of the date of issuance of such Letter of Credit. Nothing herein shall be interpreted or deemed to obligate any Agent, other than Administrative Agent, or any Lender to issue any Letter of Credit hereunder, and the obligation of Administrative Agent to act as Issuing Bank is subject to paragraphs (a) through (g) of this Section and to satisfaction of the conditions set forth in Article 3. Section 2.13 Requesting Letters of Credit. Borrower must make written application pursuant to an LC Application for any Letter of Credit at least three (3) Business Days before the date on which Issuing Bank is requested to issue such Letter of Credit. By making any such written application Borrower shall be deemed to have represented and warranted that the LC Conditions and the conditions precedent set forth in Section 3.2 will be met as of the date of issuance of such Letter of Credit. Each such LC Application must be made in such form as may mutually be agreed upon by Issuing Bank and Borrower. No more than two (2) Business Days after the LC Conditions for a Letter of Credit have been met as described in Section 2.12, Issuing Bank will issue such Letter of Credit at Issuing Bank's office in Dallas, Texas or at such other office of which Issuing Bank shall give Borrower written notice. In the event of a conflict between any provision contained in this Agreement and any provision contained in any LC Application, the provision contained in this Agreement shall control. 29 34 Section 2.14 Reimbursement of Letters of Credit. (a) Reimbursement by Borrower. Each payment of a draft or demand for payment honored by Issuing Bank under a Letter of Credit shall constitute a loan to and obligation of Borrower. Promptly upon receipt of written notice of Issuing Bank's honoring of a Letter of Credit, Borrower promises to pay to Issuing Bank, or to Issuing Bank's order at such Issuing Bank's office or at such other office of which Issuing Bank shall give Borrower written notice, on demand, in legal tender of the United States of America, any and all amounts paid by Issuing Bank under any Letter of Credit, together with interest on any such amounts from the date payment is made by Issuing Bank under such Letter of Credit until but not including the date of the repayment of such amounts to Issuing Bank, at the Base Rate; provided that if any such payment or reimbursement shall be reimbursed to Issuing Bank on the date Issuing Bank makes such payment or disbursement, interest shall be payable on the reimbursable amount at such rate for one (1) day. In the event that Borrower fails to pay when due any Matured LC Obligation owed by it to Issuing Bank, Administrative Agent may, at its option, and without any notice or further authorization from Borrower, make, pro rata on behalf of the Lenders, a Revolving Loan Advance under this Agreement to Borrower in the amount of such unpaid Matured LC Obligation (whether or not such amount is less than the minimum Revolving Loan Advance or would result in the outstanding Obligations being greater than or equal to the Facility Amount), and apply the proceeds of such Revolving Loan Advance to the payment of such Matured LC Obligation. Borrower hereby expressly requests and irrevocably authorizes Administrative Agent to do all of the foregoing. Revolving Loan Advances used to refinance Matured LC Obligations shall bear interest as provided in this Agreement and in the Loan Notes. Borrower hereby promises to pay, when and as due, all present and future levies, costs and charges whatsoever imposed, assessed, levied or collected on, under or in respect of this Agreement with respect to any Letter of Credit and any payments of principal, interest or other amounts made on or in respect of any thereof (excluding, however, any such levies, costs and charges imposed on or measured by the net income or receipts of Issuing Bank). Borrower promises to indemnify Issuing Bank against, and to reimburse Issuing Bank on demand for, any of the foregoing levies, costs or charges paid by Issuing Bank and any loss, liability, claim or expense, including interest, penalties and legal fees, that Issuing Bank may incur because of or in connection with the failure of Borrower to make any such payment of levies, costs or charges when and as due or any payment of Matured LC Obligations when and as due. Borrower's obligation to reimburse Issuing Bank under this paragraph (a) of this 30 35 Section for payments and disbursements made by Issuing Bank under any Letter of Credit issued pursuant to this Section shall be absolute and unconditional under any and all circumstances and irrespective of any setoff, counterclaim or defense to payment which Borrower may have or have had against Issuing Bank or any Lender, including, without limitation, any defense based on the failure of the demand for payment under such Letter of Credit to conform to the terms of such Letter of Credit or the legality, validity, regularity or enforceability of such Letter of Credit; provided, however, that Borrower shall not be obligated to reimburse Issuing Bank for any wrongful payment or disbursement made by Issuing Bank under any Letter of Credit as a result of acts or omissions constituting gross negligence or willful misconduct on the part of Issuing Bank or any of its officers, employees or agents. (b) Reimbursement by Lenders. Issuing Bank irrevocably agrees to grant and hereby grants to each Lender, and, each Lender irrevocably agrees to accept and purchase and hereby accepts and purchases from Issuing Bank, on the terms and conditions hereinafter stated, for such Lender's own account and risk an undivided interest equal to such Lender's Percentage Share of Issuing Bank's obligations and rights under each Letter of Credit issued hereunder and the amount of each draft paid by Issuing Bank thereunder. In the event that Borrower should fail to pay Issuing Bank on demand the amount of any draft or other request for payment drawn under a Letter of Credit as provided in paragraph (a) of this Section, each Lender shall, before 2:00 p.m., Dallas, Texas time, on the Business Day Issuing Bank shall have given notice to Lenders of Borrower's failure to so pay Issuing Bank, if such notice is given by 10:00 a.m., Dallas, Texas time (or on the Business Day immediately succeeding the day such notice is given after 10:00 a.m., Dallas, Texas time), pay to Issuing Bank at Issuing Bank's offices, or at such other office of which Issuing Bank shall have given Lenders written notice, in legal tender of the United States of America, in same day funds, such Lender's Percentage Share of the amount of such draft or other request for payment from Borrower plus interest on such amount from the date Issuing Bank shall have paid such draft or request for payment to the date of such payment by such Lender at the Federal Funds Rate. Each Lender's obligation to reimburse Issuing Bank pursuant to the terms of this Section is irrevocable and unconditional; provided, however, that Lenders shall not be obligated to reimburse Issuing Bank for any wrongful payment or disbursement made by Issuing Bank under any Letter of Credit as a result of acts or omissions constituting gross negligence or willful misconduct on the part of Issuing Bank or any of its officers, employees, Affiliates or agents. Whenever, at any time after Issuing Bank has made payment under any Letter of Credit, and has received from any Lender its Percentage Share of such payment in accordance with this subsection, Issuing Bank receives any payment 31 36 related to such Letter of Credit (whether directly from Borrower or otherwise, including proceeds of collateral applied thereto by Issuing Bank), or any payment of interest on account thereof, Issuing Bank will distribute to such Lender its Percentage Share thereof; provided, however, that in the event that any such payment received by Issuing Bank shall be required to be returned by Issuing Bank, such Lender shall return to Issuing Bank the portion thereof previously distributed by Issuing Bank to it. Each Lender shall indemnify and hold Issuing Bank harmless from and against any and all losses, liabilities (including, without limitation, liabilities for penalties), actions, suits, judgments, demands, damages, costs and expenses (including, without limitation, attorneys' fees and expenses) resulting from any failure on the part of such Lender to provide, or from any delay in providing, in accordance with this paragraph to Issuing Bank such Lender's Percentage Share of the amount of any payment or disbursement made by Issuing Bank to settle its obligations under any draft drawn under any Letter of Credit. (c) Cash Collateral Upon Event of Default. Upon the occurrence of any Default or Event of Default and the acceleration of the maturity of the Loans, an amount equal to the amount of the aggregate contingent liability of Issuing Bank and Lenders in connection with each Letter of Credit then in effect shall be deemed (as between Lenders and Borrower) to have been paid or disbursed by Issuing Bank and Lenders under such Letter of Credit (notwithstanding that such amount may not in fact have been so paid or disbursed), and Borrower shall be immediately obligated to pay to Administrative Agent for the pro rata benefit of Lenders in accordance with their respective Percentage Shares, the amount so deemed to have been so paid or disbursed, which payment shall be made by depositing Cash Collateral with Administrative Agent in accordance with the provisions of paragraph (d) of this Section. (d) Procedures for Depositing and Returning of Cash Collateral. Any cash collateral amounts received by Administrative Agent pursuant to the provisions of paragraph (c) of this Section (the "Cash Collateral") shall be deposited in a separate interest bearing cash collateral account maintained at the offices of Administrative Agent or another Lender designated by Administrative Agent under the sole dominion and control of Administrative Agent and shall be retained by Administrative Agent for the pro rata benefit of Lenders in accordance with their respective Loans and LC Obligations as collateral security for, and Borrower hereby grants to Administrative Agent for the benefit of the Lenders a security interest in such Cash Collateral including all interest accruing thereon and the proceeds thereof to secure, first the payment of the Obligations of Borrower under or in connection with its Letters of Credit, and then the other Obligations of Borrower under and in connection with this Agreement and the 32 37 other Loan Documents, including all Obligations of Borrower under its Notes pro rata to each Lender in accordance with its Loans and Percentage Share of all LC Obligations. All Cash Collateral delivered to Administrative Agent may be applied by Administrative Agent from time to time against any of Borrower's reimbursement Obligations with respect to any Letter of Credit as to which a draw is made. If and to the extent that the Default or Event of Default giving rise to the Required Lenders' demand for Cash Collateral has been cured to the reasonable satisfaction of Required Lenders and the acceleration of the Loans has been rescinded and annulled pursuant to Section 6.3 or (a) all Obligations of Borrower have been fully paid and satisfied, (b) no Letters of Credit remain outstanding and (c) Lenders' Commitments have terminated, Administrative Agent shall promptly return to Borrower, upon Borrower's request therefor, all amounts previously paid to Administrative Agent pursuant to paragraph (c) of this Section and not theretofore returned by Administrative Agent to Borrower or applied by Administrative Agent to reduce amounts payable by Borrower to Lenders under or with respect to the Letters of Credit or other amounts due to Lenders or Agents hereunder or under the other Loan Documents. Section 2.15 Letter of Credit Fees. In consideration of Issuing Bank's issuance of any Letter of Credit and each other Lender's agreement to purchase a risk participation therein, Borrower agrees to pay to Administrative Agent: (a) a letter of credit fronting fee for the account of the Issuing Bank with respect to such Letter of Credit upon issuance of each Letter of Credit in an amount equal to the greater of (x) $500 or (y) one- eighth of one percent (1/8 of 1%) per annum calculated on the face amount thereof; and (b) a letter of credit fee for the account of Lenders, to be distributed to Lenders ratably in accordance with their Percentage Shares, calculated on the face amount of each Letter of Credit in the amount of the applicable Eurodollar Margin, payable quarterly in arrears and at the expiration or termination of each Letter of Credit. Section 2.16 Capital Reimbursement. If either (a) the introduction or implementation of, or the compliance with, or any change in, or in the interpretation of, any law, rule or regulation, or (b) the introduction or implementation of or the compliance with any request, directive or guideline from any central bank or Governmental Authority (whether or not having the force of law) affects or would affect the amount of capital required to be maintained by any Lender or any corporation controlling any Lender, then, upon demand by such Lender, Borrower will immediately pay to Administrative Agent for the benefit of such Lender, from time to time as specified by such Lender, such additional amount which such Lender shall determine to be appropriate to compensate such Lender or any corporation controlling such 33 38 Lender in light of such circumstances, to the extent that such Lender reasonably determines that, because of the existence of such circumstances, the amount of any such capital would be increased or the rate of return on any such capital would be reduced, in whole or in part, by or as a consequence of the existence of such Lender's Commitments, its Loans, its Percentage Share of LC Obligations, and its other commitments under this Agreement to Borrower, subject to the provisions of Section 2.21. Section 2.17 Increased Cost of Eurodollar Portions. If any applicable domestic or foreign law, treaty, rule, directive or regulation (whether now in effect or hereinafter enacted or promulgated, including Regulation D) or any interpretation or administration thereof by any Governmental Authority charged with the interpretation or administration thereof (whether or not having the force of law): (a) shall change the basis of taxation of payments to any Lender of any principal, interest, or other amounts attributable to any Eurodollar Portion of its Loans, its Percentage Share of LC Obligations or its participation in any Swing Line Advances or its Competitive Bid Advances or otherwise due under this Agreement in respect of any Eurodollar Portion of its Loans or its participation in any Swing Line Advances or Competitive Bid Advances (other than taxes imposed on the overall net income of such Lender or any lending office of such Lender by any jurisdiction in which such Lender or any such lending office is located); (b) shall change, impose, modify, apply or deem applicable any reserve, special deposit or similar requirements in respect of any Eurodollar Portion of any Lender (excluding those for which such Lender is fully compensated pursuant to adjustments made in the definition of Adjusted Eurodollar Rate) or against assets of, deposits with or for the account of, or credit extended by, such Lender; or (c) shall impose on any Lender, the certificate of deposit market or the interbank eurocurrency deposit market any other condition affecting any Eurodollar Portion; and the result of any of the foregoing (a) through (c) is to (1) increase the cost to any Lender of funding or maintaining any Eurodollar Portion, any participation in any Swing Line Advance or any Competitive Bid Advance, as the case may be, or (2) to reduce the amount of any sum receivable by any Lender in respect of any Eurodollar Portion, Swing Line Advance or Competitive Bid Advance, as the case may be, by an amount reasonably deemed by such Lender to be material; then (i) such Lender shall promptly notify Administrative Agent and Borrower in writing of the happening of such event, (ii) Borrower shall thereafter upon demand pay to Administrative Agent for the account of such Lender such additional amount or amounts as will compensate such Lender for such additional cost or reduction, subject to the 34 39 provisions of Sections 2.21 and 2.19, and (iii) Borrower may elect, by giving to Administrative Agent and Lender not less than three (3) Business Days' notice, to convert all (but not less than all) of any such Eurodollar Portion into a part of the Base Rate Portion. Section 2.18 Availability. If (a) any change in applicable laws, treaties, rules or regulations or in the interpretation or administration thereof in any jurisdiction whatsoever, domestic or foreign, shall make it unlawful or impracticable for any Lender to fund or maintain Eurodollar Portions, or shall materially restrict the authority of any Lender to purchase or take offshore deposits of dollars ("Eurodollars"), or to issue Letters of Credit or fund its Percentage Share of LC Obligations, or (b) any Lender determines that matching deposits appropriate to fund or maintain any Eurodollar Portion are not available to it, or (c) any Lender determines that the formula for calculating the Adjusted Eurodollar Rate does not fairly reflect the cost to such Lender of making or maintaining loans based on such rates, then, upon notice by such Lender to Administrative Agent and to Borrower, Borrower's right to elect Eurodollar Portions or to apply for Letters of Credit shall be suspended to the extent and for the duration of such illegality, impracticability, restriction or condition, and all Eurodollar Portions (or portions thereof) which are then outstanding or are then the subject of any Rate Election and which cannot lawfully or practicably be maintained or funded shall immediately become or remain part of the Base Rate Portions of such Lender's Loan, subject to the provisions of Sections 2.21 and 2.19. Borrower agrees to indemnify Administrative Agent and each Lender and hold Administrative Agent and each Lender harmless against all costs, expenses, claims, penalties, liabilities and damages which may result from any such change in law, treaty, rule, regulation, interpretation or administration, subject to the provisions of Section 2.21. Section 2.19 Funding Losses. In addition to its other obligations hereunder, subject to the provisions of Section 2.21, Borrower shall indemnify each Lender against, and reimburse each Lender on demand for, any loss or expense incurred or sustained by such Lender, determined as provided in this Section, as a result of (a) any payment or prepayment (whether authorized or required hereunder or otherwise) of all or a portion of a Eurodollar Portion of Borrower on a day other than the day on which the applicable Eurodollar Interest Period ends, (b) any payment or prepayment, whether required hereunder or otherwise, of a Loan of Borrower made after the delivery, but before the effective date, of a Rate Election, if such payment or prepayment prevents such Rate Election from becoming fully effective, (c) the failure of any Revolving Loan Advance or Swing Line Advance or Competitive Bid Advance to be made to Borrower or of any Rate Election of Borrower to become effective due to any condition precedent to a Revolving Loan Advance or Swing Line Advance or Competitive Bid Advance not being satisfied, due to the inability of Administrative Agent (acting reasonably and in accordance with Section 2.18) to determine a Eurodollar Rate for a Eurodollar Portion of Borrower or due to any other action or inaction of any Designated Entity, (d) any conversion (whether authorized or required hereunder or otherwise) of all or any portion of any Eurodollar Portion of Borrower into a Base Rate Portion or into a different Eurodollar 35 40 Portion on a day other than the day on which the applicable Eurodollar Interest Period ends, (e) any payment or prepayment of all or a portion of a Swing Line Advance to Borrower on a day other than the maturity date for such Swing Line Advance or (f) any payment or prepayment of all or a portion of a Competitive Bid Advance on a day other than the maturity date for such Competitive Bid Advance. Upon the occurrence of an event as described in subsections (a) through (f) of this Section, the method to be used by each Lender to calculate the loss or expense incurred by reason of the liquidation or reemployment of deposits or other funds required by such Lender to fund or maintain Eurodollar Portions of Revolving Loan Advances, Swing Line Advances or Competitive Bid Advances, as the case may be, is as follows: Funding Loss = P x (F-R) x D/360 P = principal amount of payment, prepayment, conversion, non-borrowing or non-effective Rate Election F = Eurodollar Rate or Swing Line Rate or Competitive Bid Rate, as the case may be (adjusted for Reserve Percentage), utilized in the calculations of the Eurodollar Rate or Swing Line Rate or Competitive Bid Rate, as the case may be, on the Eurodollar Portion or Swing Line Advance or Competitive Bid Advance which is being paid, prepaid, converted, not borrowed or not subject to effective Rate Election R = reinvestment rate (as hereinafter defined) D = number of days from the date of the payment, prepayment, conversion, non-borrowing or non-effectiveness until the day on which the Eurodollar Interest Period of the Eurodollar Portion ends or the Swing Line Advance or Competitive Bid Advance matures Reinvestment rate as it is used herein will be equal to the Eurodollar Rate, adjusted for the Reserve Percentage quoted to such Lender, or the Swing Line Rate or Competitive Bid Rate that would be quoted by such Lender, as the case may be, effective for the date on which the payment, prepayment, conversion, non-borrowing or non-effectiveness occurs. For purposes of determining the reinvestment rate for purposes of this Section, the Eurodollar Rate will be the quote for either one (1) month, two (2) months, three (3) months, six (6) months, nine (9) months or twelve (12) months, the Competitive Bid Rate will be the quote for a number of days between seven (7) and 360, and the Swing Line Rate will be the quote for a number of days between one (1) and fourteen (14), whichever most closely approximates (but which may contain more or fewer days than) the number of days from the date of the payment, prepayment, conversion, non-borrowing or non-effectiveness until the last day of the relevant Eurodollar Interest Period or the scheduled maturity, as the case may be, of the Eurodollar 36 41 Portion, Competitive Bid Advance or Swing Line Advance, as the case may be, in respect of which the payment, prepayment, conversion, non-borrowing or non-effectiveness occurs; provided that if such number of days in respect of a Eurodollar Rate is the midpoint between two such periods, such rate will be the lower of the two rates for such periods. Section 2.20 Taxes. All payments by Borrower of principal of, and interest on, the Loans, the LC Obligations and all other amounts payable hereunder shall be made free and clear of and without deduction for any present or future income, excise, stamp, or franchise taxes and other taxes, fees, duties, withholdings or other charges of any nature whatsoever imposed by any taxing authority, but excluding franchise taxes and taxes imposed on or measured by any Lender's net income or receipts (such non-excluded items being called "Taxes"). In the event that any withholding or deduction from any payment to be made by Borrower hereunder is required in respect of any Taxes pursuant to any applicable law, rule or regulation, then, subject to the provisions of Section 2.21, Borrower will: (a) pay directly to the relevant authority the full amount required to be so withheld or deducted; (b) promptly forward to Administrative Agent an official receipt or other documentation satisfactory to Administrative Agent evidencing such payment to such authority; and (c) pay to Administrative Agent for the account of the applicable Lender(s) such additional amount(s) as is necessary to ensure that the net amount actually received by each Lender will equal the full amount such Lender would have received had no such withholding or deduction been required and Borrower hereby acknowledges that it is not entitled to and will not seek recovery or restitution of any amount due to any of the Lenders or Agents and paid by Borrower pursuant to this clause (c) or pursuant to the next sentence. If any Taxes are directly asserted against any Agent or any Lender with respect to any payment received by such Agent or such Lender hereunder, such Agent or such Lender may pay such Taxes and, if paid in good faith, Borrower will promptly pay such additional amounts to Administrative Agent for the account of such Lender or Agent (including any penalties, interest or expenses) as is necessary in order that the net amount received by such person after the payment of such Taxes (including any taxes on such additional amount) shall equal the amount such person would have received had no such Taxes been asserted, subject to the provisions of Section 2.21. Borrower shall pay all stamp, transaction, registration and similar taxes (including financial institutions' duties, debit taxes or other taxes payable by return and taxes passed on to any Lender or Agent by a bank or financial institution (collectively "Stamp Taxes") and, if 37 42 Borrower fails to pay any such charges or taxes after reasonable notice from any such Lender or Agent, fines and penalties) which may be payable or determined to be payable in relation to the execution, delivery, performance or enforcement of this Agreement or any Loan Document or any other transaction contemplated by any Loan Document to which Borrower is a party. Borrower hereby indemnifies each Lender and Agent against any liability resulting from delay or omission to pay such charges or taxes except to the extent the liability results from failure by the relevant Lender or Agent to pay any such tax after having been delivered funds to do so by Borrower or to the extent such liability is for fines and penalties resulting from such Lender's or Agent's failure to provide reasonable notice to Borrower as provided herein. If Borrower fails to pay any Taxes or Stamp Taxes when due to the appropriate taxing authority or fails to remit to Administrative Agent, for the account of the respective Lenders, the required receipts or other required documentary evidence, Borrower shall indemnify Lenders for any Taxes, interest or penalties that may become payable by any Lender as a result of any such failure, subject to the provisions of Section 2.21. For purposes of this Section, a distribution hereunder by Administrative Agent or any Lender to or for the account of any Lender or Agent shall be deemed a payment by the subject Borrower. Borrower waives any statutory right to recover from any Agent or any Lender any amount due to any such Agent or Lender and paid by Borrower under this Section. On or prior to the first date on which interest or fees are payable hereunder for the account of any Lender, each Lender that is organized under the laws of a jurisdiction other than the United States shall execute and deliver to Administrative Agent, three (3) or more (as Administrative Agent may reasonably request) United States Internal Revenue Service Forms 1001 or 4224 or such other forms or documents (or successor forms or documents), appropriately completed, as may be applicable to establish the extent, if any, to which a payment to such Lender is exempt from withholding or deduction of Taxes. Each Lender which so delivers a Form 1001 or 4224 further undertakes to deliver to Administrative Agent three (3) additional copies of such form (or a successor form) on or before the date that such form expires or becomes obsolete or after the occurrence of any event requiring a change in the most recent form so delivered by it, and such amendments thereto or extensions or renewals thereof as may be reasonably requested by Administrative Agent, in each case certifying that such Lender is entitled to receive payments from Borrower under this Agreement and the Notes without deduction or withholding of any United States federal income taxes, unless an event (including without limitation any change in treaty, law or regulation) has occurred prior to the date on which any such delivery would otherwise be required which renders all such forms of the type previously delivered inapplicable or which would prevent such Lender from duly completing and delivering such form with respect to it and such Lender advises Administrative Agent that it is not capable of receiving such payments on the basis reflected in such previously delivered form without any deduction or withholding of United States federal income tax. Administrative Agent shall provide one (1) copy of each 38 43 of such forms or documents so provided to Borrower and Documentation Agent. Section 2.21 Make-Whole Qualifications. Each Lender's claims for reimbursements, payments, indemnities or otherwise under Sections 2.16, 2.17, 2.18, 2.19 and 2.20 and Borrower's obligation with respect thereto, shall be limited and qualified by and subject to the following: (a) Borrower's obligation to pay, satisfy or recognize such claim shall be limited to costs or losses incurred within one (1) year immediately prior to any demand or request therefor upon Borrower; (b) each Lender's demand for reimbursement, payment or indemnity from Borrower must be limited to that which is being generally applied at the time by such Lender for comparable borrowers and credits subject to credit agreements similar to this Agreement, but without regard to provisions similar to this Section; (c) each Lender which asserts its rights with respect thereto or which is seeking or imposing such reimbursement, payment or indemnity shall provide evidence regarding the basis of such claim and the calculation and application thereof in reasonable detail and, in determining such amount, each Lender may use reasonable methods of attribution and averaging; (d) each Lender which is seeking payment or reimbursement pursuant to Section 2.20 shall, if so requested by Borrower, use reasonable efforts (subject to the overall policy considerations of such Lender) to designate a different lending office hereunder if to do so will avoid the need for, or reduce the amount of, any such payment or reimbursement; provided that, Lender would, in its sole but reasonable determination, suffer no material economic, legal or regulatory disadvantage or burden; (e) Borrower may, in its sole discretion, elect, unless and until the applicable Lender notifies Borrower that the circumstances giving rise thereto no longer apply to such Lender, that, to the extent that a Lender's claims for such reimbursements, payments or indemnities would be reduced thereby, that subject to Section 2.19, (1) all Loans to Borrower which would otherwise be made by such Lender as Eurodollar Portions shall be made instead as Base Rate Portions (all of which interest and principal shall be payable as provided herein with respect to the related Eurodollar Portions of the Lenders), and (2) after each Eurodollar Portion has been repaid, all payments of principal which would otherwise would be applied to repay such Eurodollar Portion shall be applied to repay Base Rate Portions instead; and 39 44 (f) Borrower may designate a replacement Lender (which may be one (1) or more of the then existing Lenders hereunder and which shall be reasonably satisfactory to Administrative Agent) to purchase the Notes and Percentage Share of LC Obligations, in each case without recourse, and assume the Commitments and all other obligations hereunder of any Lender that has suspended the availability of Eurodollar Portions pursuant to Section 2.18 or that has demanded reimbursement, payment or indemnity under Sections 2.16, 2.17, 2.18, 2.19 or 2.20, and such Lender shall be obligated to sell, transfer and deliver all of its Notes, and Percentage Share of LC Obligations to such replacement Lender for the outstanding principal amount of such Notes, plus Lender's Percentage Share of LC Obligations, plus in each case, accrued interest thereon and such Lender's portion of accrued but unpaid fees through the date of such purchase, and permit such replacement lender to assume its Commitments. Borrower shall be obligated to pay all additional amounts due to the Lender being replaced pursuant to Sections 2.16, 2.17, 2.18, 2.19 and 2.20 through the date of such purchase and assumption; provided, that if the replacement Lender fails to purchase all such rights and interests and assume all such Commitments on the specified date in accordance herewith, Borrower shall continue to be obligated to pay such amounts to such Lender which was to have been replaced and provided further that Borrower shall pay any Taxes or Stamp Taxes, if any, as a result of such transfer. Section 2.22 Competitive Bid Advances. (a) In addition to borrowings pursuant to Section 2.1(a) or Section 2.4, Borrower may request each Lender severally to submit offers (herein called a "Competitive Bid Offer") to make advances to Borrower on any Business Day during the Loan Commitment Period as provided in this Section (herein called "Competitive Bid Advances"); provided, however, that each Lender may in its sole discretion, but shall have no obligation whatsoever to submit such offers, and Borrower may, but shall have no obligation to, accept any such offers. (b) Procedure for Competitive Bid Advances. (i) Borrower may request Competitive Bid Advances by delivering a request for a Competitive Bid Advance to each Lender (which has indicated to Borrower its interest in making a Competitive Bid Advance) and Administrative Agent not later than 9:00 a.m., Dallas, Texas time, one (1) Business Day prior to the proposed borrowing date. Each request for a Competitive Bid Advance shall be in substantially the form of Exhibit N hereto (herein called a "Request for Competitive Bid Offer") and may solicit bids for Competitive Bid Advances having not more than three (3) alternative maturity dates and for Competitive Bid Advances in any 40 45 respective principal amount equal to $10,000,000 or an integral multiple of $1,000,000 in excess thereof for each maturity date requested. The maturity date for each Competitive Bid Advance shall be not less than fifteen (15) days nor more than 360 days after the borrowing date therefor (and in any event not after the Maturity Date). (ii) Upon receipt of a Request for Competitive Bid Offer, any Lender that elects, in its sole discretion, to do so, shall irrevocably offer to make one (1) or more Competitive Bid Advances at a fixed rate of interest determined by such Lender in its sole discretion for each such Competitive Bid Advance. Any such irrevocable offer shall be made by delivering a Competitive Bid Offer to Administrative Agent and to Borrower, before 9:00 a.m., Dallas, Texas time (or, in the case of a Competitive Bid Offer by Administrative Agent, before 8:45 a.m., Dallas, Texas time), on the proposed borrowing date, setting forth the maximum amount of Competitive Bid Advances for each maturity date, and the aggregate maximum amount for all maturity dates, which such Lender would be willing to make (which amounts may exceed such Lender's Percentage Share of the Commitments) and the fixed rate of interest at which such Lender is willing to make each such Competitive Bid Advance, which fixed rate of interest may or may not be, in such Lender's discretion, different for each Competitive Bid Advance (respectively herein a "Competitive Bid Rate"). Borrower shall pay to Administrative Agent a fee of $500 on each day that Borrower accepts a Competitive Bid Offer. (iii) The Competitive Bid Offer delivered by each Lender in response to a Request for Competitive Bid Offer shall set forth an amount proposed to be loaned by such Lender for each maturity date requested by Borrower that is equal to $10,000,000 or an integral multiple of $1,000,000 in excess thereof. Any Competitive Bid Offer by any Lender that: (A) does not substantially conform to the form of Exhibit O hereto, (B) contains qualifying, conditional or similar language, (C) proposes terms other than or in addition to those set forth in the applicable Request for Competitive Bid Offer or (D) is received by Borrower after the applicable time specified in this subsection, shall be rejected by Borrower and Administrative Agent (and Administrative Agent shall notify the relevant Lender of such rejection for one or more of the matters described in the foregoing (A) through (D) by telephone and telecopy as soon as practicable thereafter). (iv) Borrower shall before 10:00 a.m., Dallas, Texas time, on the proposed 41 46 borrowing date either, in its absolute discretion: (A) withdraw such Request for Competitive Bid Offer by giving telephonic notice to that effect; (B) accept one (1) or more of the Competitive Bid Offers by giving telephonic notice to Administrative Agent (immediately confirmed by delivery to Administrative Agent by facsimile transmission of a Bid Acceptance) of the amount of Competitive Bid Advance(s) for each relevant maturity date to be made by the relevant Lender(s) (which amount for each such maturity date shall be equal to or less than the maximum amount for such maturity date specified in the Competitive Bid Offer of such Lender(s), and for all maturity dates included in such Competitive Bid Offer shall be equal to or less than the aggregate maximum amount specified in such Request for Competitive Bid Offer for all such maturity dates) and reject any Competitive Bid Offers not accepted by Borrower by giving telephonic notice to Administrative Agent of such rejection; provided, however, that (1) Borrower may not accept Competitive Bid Offers for any maturity date in an aggregate principal amount in excess of the maximum principal amount requested in the related Request for Competitive Bid Offer (and Competitive Bid Advances allocated to a Lender on a borrowing date for each relevant maturity date shall be in a principal amount equal to $10,000,000 or an integral multiple of $1,000,000 in excess thereof); and (2) Administrative Agent shall notify the Lender that submitted a Competitive Bid Offer for such Business Day of Borrower's decision by telecopying to each such Lender a copy of the Bid Acceptance by no later than 12:00 noon, Dallas, Texas time, on the borrowing date specified in the Request for Competitive Bid Offer; or (C) Borrower may accept or reject any Competitive Bid Offer(s) in whole or in part; provided that after giving effect to any such accepted Competitive Bid Offer(s), the sum of (i) the aggregate principal amount of the Revolving Loans and Swing Line Advances outstanding at such time, (ii) the aggregate principal amount of LC Obligations outstanding at such time, and (iii) the aggregate principal amount of Competitive Bid Advances outstanding at such time, does not exceed the Facility Amount. (v) If Borrower notifies Administrative Agent that a Request for Competitive 42 47 Bid Offer is withdrawn pursuant to clause (iv) above, the Competitive Bid Advance requested thereby shall not be made. (vi) Each Lender which is to make a Competitive Bid Advance shall, before 1:00 p.m., Dallas, Texas time, on the borrowing date specified in the Request for Competitive Bid Offer applicable thereto, make available to Administrative Agent in immediately available funds the amount of each Competitive Bid Advance to be made by such Lender. Administrative Agent shall deposit such funds to an account designated by Borrower by no later than 1:15 p.m., Dallas, Texas time, on such date. (vii) Borrower shall repay to Administrative Agent, for the account of each Lender which has made a Competitive Bid Advance, on the maturity date of each Competitive Bid Advance (such maturity date being that specified by Borrower for repayment of such Competitive Bid Advance in the related Request for Competitive Bid Offer) the then unpaid principal amount of such Competitive Bid Advance. Borrower shall not have the right to prepay any principal amount of any Competitive Bid Advance. If any Lender makes a Competitive Bid Advance on a day on which Borrower is to repay all or any part of an outstanding Competitive Bid Advance from such Lender, if requested by Borrower, such Lender shall apply the proceeds of its new Competitive Bid Advance to make such repayment and, in such instance, only an amount equal to the difference (if any) between the amount being borrowed and the amount being repaid shall be made available by such Lender to Administrative Agent as provided in Section 2.22(b)(vi), or remitted by Borrower to Administrative Agent as provided in this Section 2.22(b)(vii), as the case may be. (viii) Borrower shall pay interest on the unpaid principal amount of each Competitive Bid Advance from the borrowing date to the stated maturity date thereof, at the rate of interest determined pursuant to clause (b) (ii) above (calculated on the basis of a 360 day year for actual days elapsed including the first but excluding the last), but not in excess of the Maximum Lawful Rate, payable on the maturity date with respect to such Competitive Bid Advance and, if such maturity date is more than 90 days after the date of making such Competitive Bid Advance, on such ninetieth day and each ninetieth day occurring after such ninetieth day until the maturity date. If all or a portion of the principal of or interest on any Competitive Bid Advance shall not be paid when due (whether at the stated maturity, by acceleration or otherwise), without limiting any rights of any Lender under this Agreement, (i) such overdue principal 43 48 amount shall bear interest from the date on which such payment was due (other than on the scheduled maturity date with respect thereto) at the Default Rate, but not in excess of the Maximum Lawful Rate, until paid in full (as well as after as before judgment) and (ii) such overdue interest shall bear interest from the date on which payment was due at the Default Rate, but not in excess of the Maximum Lawful Rate, until paid in full (as well as after as before judgment). (c) The Competitive Bid Advances made by each Lender shall be evidenced by a single promissory note of Borrower payable to the order of such Lender substantially in the form of Exhibit A-3 attached hereto, with appropriate insertions (herein called a "Competitive Bid Note"). The date, amount, Competitive Bid Rate and maturity date of each Competitive Bid Advance made by a Lender to Borrower, and each payment made on account of the principal thereof, shall be recorded by such Lender on its books. (d) The Competitive Bid Advances will be used by Borrower to provide working capital and for the general business purposes of Borrower and its Subsidiaries. No Competitive Bid Advances shall be used for the purpose of purchasing or carrying any Margin Stock in violation of the Margin Regulations. (e) The obligation of Lenders to make each Competitive Bid Advance after timely acceptance by Borrower is further subject to the conditions contained in Article 3. (f) Borrower shall not be required to accept Competitive Bid Offers on the basis of the lowest Competitive Bid Rate offered, but may in its sole discretion accept any Competitive Bid Offer regardless of the Competitive Bid Rate(s) offered.

and (y) to repay all Obligations and other amounts and to cause all outstanding Letters of Credit to be terminated and the originals thereof to be returned to the Issuing Bank as soon as practical after receipt of the reasonable request of Managing Agents pursuant to the foregoing clause (x); provided, however, that the foregoing events which affect only Restricted Subsidiaries that (a) are not guarantors of the Obligations, and (b) are immaterial (as determined by the Managing Agents), shall not constitute "Events of Default" under this Agreement. It is agreed by the parties hereto that so long as Borrower or any Restricted Subsidiary has made reasonable efforts under the circumstances to obtain the approvals required by Section 205(10) of the Corporations Law of Australia (if applicable), the foregoing paragraphs (k)(2), (l) and (m) shall not require any Restricted Subsidiaries to provide any pledge or guaranty prohibited by corporate law unless the requirements of such Section 205(10) of the Corporations Law of Australia, to the extent applicable, have been satisfied; and (k) Any "Event of Default" as defined in the Canadian Credit Facility or the 364 Day Credit Facility shall occur; provided that the occurrence of a "Default" as defined in the Canadian Credit Facility or the 364 Day Credit Facility shall constitute a Default under this Agreement; provided further that if such "Default" is cured or waived under the Canadian Credit Facility or the 364 Day Credit Facility, as applicable, then such "Default" shall no longer constitute a Default under this Agreement. Upon the occurrence of an Event of Default described in Section 6.1(h)(1), (2) or (3) with respect to Borrower, the Commitments shall automatically terminate and all of the Obligations shall thereupon be immediately due and payable, without demand, presentment, notice of demand or of dishonor and nonpayment, protest, notice of protest, notice of intention to accelerate, declaration or notice of acceleration, or any other notice or declaration of any kind, all of which are hereby expressly waived by Borrower and each Designated Entity who at any 66 71 time ratifies or approves this Agreement. During the continuance of any other Event of Default, Administrative Agent at any time and from time to time upon written instructions from Required Lenders (which, for purposes of this sentence only, shall be determined giving effect to each Lender's outstanding Swing Line Advances and Competitive Bid Advances) shall, by notice to Borrower (but otherwise without notice to any other Designated Entity), declare the Commitments to be terminated, and/or declare any or all of the Obligations immediately due and payable, and all such Obligations shall thereupon be immediately due and payable, without demand, presentment, notice of demand or of dishonor and nonpayment, protest, notice of protest, notice of intention to accelerate, declaration or notice of acceleration, or any other notice or declaration of any kind, all of which are hereby expressly waived by Borrower and each Designated Entity who at any time ratifies, approves or guaranties this Agreement and/or require Borrower to deposit Cash Collateral with Administrative Agent in an amount determined in accordance with paragraph (c) of Section 2.14. Section 6.2 Remedies. If any Default shall occur and be continuing, each Lender or Administrative Agent on behalf of Lenders may protect and enforce its rights under the Loan Documents by any appropriate proceedings, including, without limitation, proceedings for specific performance of any covenant or agreement contained in any Loan Document, and each Lender may enforce the payment of any Obligations due it or enforce any other legal or equitable rights which it may have. Additionally, under such circumstances, the Required Lenders or, at the direction of Required Lenders, the Trustee (or Collateral Agent) may proceed to protect the Lenders' rights under the Security Instruments. All rights, remedies and powers conferred upon Administrative Agent and Lenders under the Loan Documents are cumulative and not exclusive of any other rights, remedies or powers available under the Loan Documents or at law or in equity. Section 6.3 Annulment of Acceleration. If a declaration of acceleration is made pursuant to this Article 6, then Required Lenders, by written notice to Borrower and Administrative Agent, may collectively rescind and annul such declaration in its entirety; provided, that at the time such declaration is annulled and rescinded: (a) no judgment or decree has been entered for the payment of any moneys due pursuant to any Note or this Agreement; (b) all arrears of interest upon all the Notes and all other sums payable under the Notes and this Agreement (other than principal amounts which may have become due as a result of acceleration), including interest upon overdue interest, to the extent payment thereof is lawful, shall have been duly paid; and (c) each and every other Event of Default which has theretofore occurred shall have been waived pursuant to Section 8.1 or otherwise made good or cured. Section 6.4 Indemnity. Borrower hereby indemnifies each Agent and each Lender, from and against any and all liabilities, obligations, claims, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements (including reasonable fees of attorneys, accountants, experts and advisors) of any kind or nature whatsoever (in this Section collectively called "liabilities and costs") which to any extent (in whole or in part) may be 67 72 imposed on, incurred by, or asserted against such Agent or such Lender result of, arising out of, relating to or in connection with: as a (a) the Loan Documents to which Borrower or one or more of its Subsidiaries is a party or the rights provided therein (including the enforcement or defense thereof); (b) the direct or indirect application or proposed application of the proceeds of any Loan or Letter of Credit to or for Borrower or any of its Subsidiaries; (c) any transaction financed or to be financed in whole or in part, directly or indirectly, with the proceeds of any Loan or Letter of Credit to or for Borrower or any of its Subsidiaries; (d) any investigation, litigation or proceeding related to any environmental cleanup, audit, compliance or other matter (including enforcement) relating to any Environmental Law or the condition of any facility or property owned, leased or operated by Borrower or any of its Subsidiaries; or (e) the presence on or under, or the escape, seepage, leakage, spillage, discharge, emission, discharging or releases from, any facility owned or operated by Borrower or any of its Subsidiaries of any hazardous or toxic substance (including any liabilities and costs under any Environmental Law), regardless of whether caused by, or within the control of, Borrower or any of its Subsidiaries; or any misrepresentation, inaccuracy or any breach in or of Section 4.1(j) or Section 5.1(i) by or with respect to Borrower or any of its Subsidiaries. The foregoing indemnification shall not apply to the extent such liabilities and costs are determined to have resulted or been caused, in whole or in part, by the gross negligence or willful misconduct on the part of such Agent or Lender. THE FOREGOING INDEMNIFICATION SHALL APPLY WHETHER OR NOT SUCH LIABILITIES AND COSTS ARE IN ANY WAY OR TO ANY EXTENT CAUSED, IN WHOLE OR IN PART, BY ANY NEGLIGENT ACT OR OMISSION OF ANY KIND EXCEPT AS PROVIDED BY THE IMMEDIATELY PRECEDING SENTENCE. In the event that any claim or demand for which Borrower would be liable to any Agent or any Lender under this Section is asserted against or sought to be collected from any Agent or any Lender by a third party, Agent or such Lender shall promptly notify Borrower of such claim or demand. Borrower shall have the lesser of: (i) thirty (30) Business Days from receipt of the above notice; or (ii) three (3) Business Days prior to the expiration of any period after which a default judgment may be entered against such Agent or Lender (the "Notice Period") to notify such Agent and/or Lender whether or not Borrower desires, at the sole cost and expense of Borrower, to defend such Agent and/or Lender against such claim or demand. In the event 68 73 that Borrower notifies such Agent and/or Lender within the Notice Period, that it desires to defend such Agent and/or Lender against such claim or demand, Borrower shall have the right to settle or otherwise dispose of such claim or demand (other than claims alleging criminal violations) on such terms as Borrower, with the consent of the indemnified party (which consent shall not be unreasonably withheld) shall deem appropriate; provided that: (w) counsel designated by Borrower is reasonably acceptable to the Managing Agents and the affected Lender; (x) Borrower will have acknowledged in writing that this Section will cover any liabilities and costs in any such claim or demand; (y) in the sole determination of the Managing Agents and the affected Lender, Borrower will have the financial ability to pay such liabilities and costs; and (z) Borrower shall thereafter consult with the Managing Agents and the affected Lender with respect to such claim or demand; and provided further, that each of Agents and the affected Lender shall have the right at all times to participate in any proceeding, at their sole cost and expense, subject, however, to Borrower's right to control the defense of all proceedings concerning such claim or demand. In the event that Borrower fails to give such Agent and/or Lender such notice, such Agent and/or Lender may defend against such claim or demand; provided, however, that Borrower's obligation to reimburse such Agent and/or Lender shall be limited to a single law firm of such Agent and/or Lender (unless Borrower otherwise consents, which consent shall not be unreasonably withheld); provided further, that Borrower shall have the right at all times to participate in any such proceeding, at its sole cost and expense, subject, however, to the right of such Agent and/or Lender to control the defense of all proceedings concerning such claim or demand. As used in this Section, the terms "Agent" and "Lender" shall refer not only to the Persons designated as such in Section 1.1 but also to each director, officer, agent, attorney, employee and representative of such Person. ARTICLE 7 AGENTS Section 7.1 Appointment and Authority. NationsBank of Texas, N.A. is hereby appointed Administrative Agent hereunder and under each other Loan Document, CIBC Inc. is hereby appointed Documentation Agent hereunder and under each other Loan Document, 69 74 Morgan Guaranty Trust Company of New York is hereby appointed Documentation Agent hereunder and under each other Loan Document and The Chase Manhattan Bank is hereby appointed Syndication Agent hereunder and under each other Loan Document, each Co-Agent is hereby appointed Co-Agent hereunder and under each other Loan Document, and each of the Lenders hereby authorizes each such Agent to act as the agent of such Lender hereunder and each other Loan Document to the extent provided herein or therein. In addition, each Lender hereby irrevocably authorizes Administrative Agent, and Administrative Agent hereby undertakes, to receive payments of principal, interest due hereunder as specified herein and to act as Collateral Agent under the Security Instruments. In addition, each Lender hereby authorizes each Agent, and each Agent hereby undertakes to take all other actions and to exercise such powers under the Loan Documents as are specifically delegated to such Agent by the terms hereof or thereof, together with all other powers reasonably incidental thereto. No Co-Agent has any duties or responsibilities whatsoever as Co-Agent (as opposed to its capacity as Lender) under or in connection with this Agreement or any of the Loan Documents. The relationship of each Agent to Lender is only that of one commercial bank acting as administrative agent for others, and nothing in the Loan Documents shall be construed to constitute any Agent a trustee or other fiduciary for any holder of any of the Notes or of any participation therein or in the LC Obligations, nor to impose on any Agent duties and obligations other than those expressly provided for in the Loan Documents. None of the Agents shall have implied duties to Lenders, or any obligations to Lenders to take any action under the Loan Documents, except any action by an Agent specifically provided by the Loan Documents to be taken by such Agent. With respect to any matters not expressly provided for in the Loan Documents and any matters which the Loan Documents place within the discretion of any Agent, such Agent shall not be required to exercise any discretion or take any action, and each such Agent may request instructions from Lenders with respect to any such matter, in which case such Agent shall be required to act or to refrain from acting (and shall be fully protected and free from liability to any and all Lenders and Agents in so acting or refraining from acting) upon the instructions of Required Lenders (including itself); provided, however, that no Agent shall be required to take any action which exposes it to a risk of personal liability that it considers unreasonable or which is contrary to the Loan Documents or to applicable law unless indemnified to its satisfaction by Lenders or Borrower. Upon receipt by Administrative Agent from Borrower of any communication calling for action on the part of Lenders or upon notice from any Lender to Administrative Agent of any Default or Event of Default, Administrative Agent shall promptly notify each Lender thereof. Section 7.2 Agent's Reliance. No Agent or any of their respective directors, officers, agents, attorneys, or employees shall be liable for any action taken or omitted to be taken by any of them under or in connection with the Loan Documents, including their negligence of any kind, except that each shall be liable for its own gross negligence or willful misconduct. Without limiting the generality of the foregoing, each Agent: 70 75 (a) may treat the payee of any Note as the holder thereof until Administrative Agent receives written notice of the assignment or transfer thereof in accordance with this Agreement, signed by such payee and in form satisfactory to Administrative Agent; (b) may consult with legal counsel (including counsel for Borrower), independent public accountants and other experts selected by such Agent and shall not be liable for any action taken or omitted to be taken in good faith by it in accordance with the advice of such counsel, accountants or experts; (c) makes no warranty or representation to any Lender or to any other Agent and shall not be responsible to any Lender or Agent for any statements, warranties or representations made in or in connection with the Loan Documents by any other Person; (d) shall not have any duty to ascertain or to inquire as to the performance or observance of any of the terms, covenants or conditions of the Loan Documents on the part of any Designated Entity or to inspect the property (including the books and records) of any Designated Entity; (e) shall not be responsible to any Lender or to any other Agent for the due execution (other than its own due execution and delivery), legality, validity, enforceability, genuineness, existence, sufficiency or value of any Loan Document, the Credit Facility Agreement or any instrument or document furnished in connection herewith, or any collateral; (f) may rely upon the representations and warranties of any Designated Entity and the Lenders in exercising its powers hereunder; (g) shall not be responsible for the satisfaction of any condition specified in Article 3, except receipt by an Agent of items required to be delivered to such Agent; and (h) shall incur no liability under or in respect of the Loan Documents by acting upon any notice, consent, certificate or other instrument or writing (including any telecopy, telegram, cable or telex) believed by it to be genuine and signed or sent by the proper Person or Persons. Section 7.3 Lenders' Credit Decisions. Each Lender acknowledges that it has, independently and without reliance upon any Agent or any other Lender, made its own analysis of Designated Entities and the transactions contemplated hereby and its own independent decision to enter into this Agreement and the other Loan Documents. Each Lender also 71 76 acknowledges that it will, independently and without reliance upon any Agent or any other Lender and based on such documents and information as it shall deem appropriate at the time, continue to make its own credit decisions in taking or not taking action under the Loan Documents. Section 7.4 Indemnification. Each Lender agrees to indemnify each Agent (to the extent not reimbursed by Borrower within ten (10) days after demand) from and against such Lender's Percentage Share of any and all liabilities, obligations, claims, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements (including reasonable fees of attorneys, accountants, experts, and advisors) of any kind or nature whatsoever (in this Section collectively called "liabilities and costs") which to any extent (in whole or in part) may be imposed on, incurred by, or asserted against such Agent growing out of, resulting from or in any other way associated with any of the Loan Documents and the transactions and events (including, without limitation, the enforcement thereof) at any time associated therewith or contemplated therein. THE FOREGOING INDEMNIFICATION SHALL APPLY WHETHER OR NOT SUCH LIABILITIES AND COSTS ARE IN ANY WAY OR TO ANY EXTENT CAUSED, IN WHOLE OR IN PART, BY ANY NEGLIGENT ACT OR OMISSION OF ANY KIND BY ANY AGENT, PROVIDED ONLY THAT NO LENDER SHALL BE OBLIGATED UNDER THIS SECTION TO INDEMNIFY AN AGENT FOR THAT PORTION, IF ANY, OF ANY LIABILITIES AND COSTS WHICH IS THE SOLE RESULT OF SUCH AGENT'S OWN INDIVIDUAL GROSS NEGLIGENCE OR WILLFUL MISCONDUCT, AS DETERMINED IN A FINAL JUDGMENT OF A COURT OF COMPETENT JURISDICTION. Cumulative of the foregoing, each Lender agrees to reimburse Administrative Agent, each Documentation Agent and Syndication Agent promptly upon demand for such Lender's Percentage Share of any costs and expenses to be paid to Administrative Agent, the Documentation Agent or the Syndication Agent by Borrower under Section 5.1(h) to the extent that Administrative Agent, the Documentation Agent or the Syndication Agent is not timely reimbursed for such expenses by Borrower as provided in such section. As used in this Section the term "Agents" shall refer not only to the Person(s) designated as such in Section 1.1 but also to each director, officer, agent, attorney, employee and representative of such Person(s). Section 7.5 Rights as Lender. In their respective capacity as a Lender, each Agent shall have the same rights and obligations as any Lender and may exercise such rights as though it were not an Agent. Each Agent may accept deposits from, lend money to, act as trustee under indentures of, and generally engage in any kind of business with any of Designated Entities or their Affiliates, all as if it were not an Agent hereunder and without any duty to account therefor to any other Lender. Section 7.6 Sharing of Set-Offs and Other Payments. Each Agent and Lender agrees that if it shall, whether through the exercise of rights under security documents or rights of banker's lien, setoff, or counterclaim against any Designated Entity or otherwise, obtain 72 77 payment of a portion of the aggregate Obligations owed to it (other than in respect of its Swing Line Advances and its Competitive Bid Advances) which, taking into account all distributions made by Administrative Agent under Section 2.11, causes such Agent or such Lender to have received more than it would have received had such payment been received by Administrative Agent and distributed pursuant to Section 2.11 (or, in the case of Swing Line Advances paid as provided in Section 2.5(c) or in the case of Competitive Bid Advances paid as provided in Section 2.22(b)), then it shall be deemed to have simultaneously purchased and shall be obligated to purchase interests in the Obligations as necessary to cause Administrative Agent and all Lenders to share all payments (other than in respect of Swing Line Advances and Competitive Bid Advances) as provided for in Section 2.11, and such other adjustments shall be made from time to time as shall be equitable to ensure that all Agents and all Lenders share all payments of Obligations (other than in respect of its Swing Line Advances and Competitive Bid Advances) as provided in Section 2.11. If any Agent or any Lender, whether in connection with setoff of amounts which might be subject to setoff or otherwise, receives collateral or other protection for its Obligations or such amounts which might be subject to setoff, such Agent or Lender agrees, promptly upon demand, to take such action necessary so that all Agents and all Lenders share in the benefits of such collateral ratably in proportion to the Obligations owing to each of them. Nothing herein contained shall in any way affect the right of any Agent or any Lender to obtain payment (whether by exercise of rights of banker's lien, set-off or counterclaim or otherwise) of indebtedness other than the Obligations. Borrower expressly consents to the foregoing arrangements and agrees that any holder of any such interest or other participation in the Obligations, whether or not acquired pursuant to the foregoing arrangements, may to the fullest extent permitted by law exercise any and all rights of banker's lien, set-off, or counterclaim as fully as if such holder were a holder of the Obligations in the amount of such interest or other participation. If all or any part of any funds transferred pursuant to this Section is thereafter recovered from the seller under this Section which received the same, the purchase provided for in this Section shall be deemed to have been rescinded to the extent of such recovery, together with interest, if any, if interest is required pursuant to court order to be paid on account of the possession of such funds prior to such recovery. Section 7.7 Investments. Whenever Administrative Agent in good faith determines that it is uncertain about how to distribute to Lenders any funds which it has received, or whenever Administrative Agent in good faith determines that there is any dispute among Lenders about how such funds should be distributed, Administrative Agent may choose to defer distribution of the funds which are the subject of such uncertainty or dispute. If Administrative Agent in good faith believes that the uncertainty or dispute will not be promptly resolved, or if Administrative Agent is otherwise required to invest funds pending distribution to Lenders, Administrative Agent may invest such funds pending distribution (at the risk of the subject Borrower); all interest on any such investment shall be distributed upon the distribution of such investment and in the same proportion and to the same Persons as such investment. All moneys received by Administrative Agent for distribution to Lenders (other than to the 73 78 Person who is Administrative Agent in its separate capacity as a Lender) shall be held by Administrative Agent pending such distribution solely as Administrative Agent for such Lenders, and Administrative Agent shall have no equitable title to any portion thereof. Section 7.8 Benefit of Article 7. The provisions of this Article (other than the following Section 7.9) are intended solely for the benefit of Agent and Lenders, and no Designated Entity shall be entitled to rely on any such provision or assert any such provision in a claim or defense against Agent or any Lender. Agent and Lenders may waive or amend such provisions as they desire without any notice to or consent of any Designated Entity. Section 7.9 Resignation and Removal. Any Agent may resign at any time by giving written notice thereof to Lenders and Borrower. Each such notice shall set forth the date of such resignation. Majority Lenders or Borrower, with the consent (which shall not be unreasonably withheld) of Majority Lenders (other than Agent to be removed) shall be entitled to remove any Agent. Upon any such resignation or removal, Borrower may, with the written concurrence (which shall not be unreasonably withheld) of Majority Lenders (exclusive of any such resigned or removed Agent), designate a successor Agent. If, within fifteen (15) days after the date of such resignation or removal, Borrower makes no such designation or such written concurrence is not given, Majority Lenders (exclusive of any such resigned or removed Agent) shall, with the consent of Borrower (which consent shall not be unreasonably withheld or delayed), have the right to appoint a successor Agent. A successor must be appointed for any retiring Managing Agent, and such Managing Agent's resignation shall become effective when such successor accepts such appointment. Upon the acceptance of any appointment as a Managing Agent hereunder by a successor Managing Agent and the satisfaction of all obligations on the part of such retiring or removed Managing Agent necessary to facilitate succession, the retiring or removed Managing Agent, as the case may be, shall be discharged from its duties and obligations under this Agreement and the other Loan Documents. After any Agent's resignation or removal hereunder, the provisions of this Article 7 shall continue to inure to its benefit as to any actions taken or omitted to be taken by it while it was Agent under the Loan Documents. Any out-going Agent shall promptly execute all assignments and other documents necessary to effectuate the transfer of the agency in connection with this Agreement and shall promptly deliver all original documents and any collateral in its possession to the successor Agents. ARTICLE 8 MISCELLANEOUS Section 8.1 Waivers and Amendments. No failure or delay (whether by course of conduct or otherwise) by any Agent or any Lender in exercising any right, power or remedy which any Agent or Lender may have under any of the Loan Documents shall operate as a waiver thereof or of any other right, power or remedy, nor shall any single or partial exercise 74 79 by any Agent or Lender of any such right, power or remedy preclude any other or further exercise thereof or of any other right, power or remedy. No waiver of any provision of any Loan Document and no consent to any departure therefrom shall ever be effective unless it is in writing and signed as provided below in this Section, and then such waiver or consent shall be effective only in the specific instances and for the purposes for which given and to the extent specified in such writing. No notice to or demand on any Designated Entity shall in any case of itself entitle any Designated Entity to any other or further notice or demand in similar or other circumstances. This Agreement and the other Loan Documents set forth the entire understanding between the parties hereto with respect to the transactions contemplated herein and therein and supersede all prior discussions and understandings with respect to the subject matter hereof and thereof, and no waiver, consent, release, modification or amendment of or supplement to this Agreement or the other Loan Documents shall be valid or effective against any party hereto unless the same is in writing and signed by (a) if such party is a Designated Entity, by such Designated Entity, (b) if such party is an Agent, by such Agent and (c) if such party is a Lender, by such Lender or by Administrative Agent on behalf of Lenders with the written consent of Required Lenders (or without further consent than that already provided herein in the circumstances provided in Section 8.7). Notwithstanding the foregoing or anything to the contrary herein or in any other Loan Document, no Agent shall, without the prior consent of each Lender, execute and deliver on behalf of any Lender any waiver or amendment which would: (i) increase the Commitment of such Lender or subject such Lender to any additional obligations; (ii) reduce or forgive any fees hereunder, or the principal of, or interest on, such Lender's Notes or LC Obligations; (iii) postpone any date fixed for any payment of any fees hereunder, or principal of, or interest on, such Lender's Notes or LC Obligations; (iv) amend the definitions herein of "Required Lenders" or "Majority Lenders" or otherwise change the aggregate amount of Percentage Shares which is required for Administrative Agent, any other Agent, Lenders or any of them to take any particular action under the Loan Documents; (v) release collateral (except as expressly contemplated by this Agreement) or any Borrower from its obligation to pay such Lender's Notes or LC Obligations or any Restricted Subsidiary from its Guaranty (except upon the Restricted Subsidiary becoming an Unrestricted Subsidiary as specified in this Agreement); (vi) 75 amend this Section 8.1; 80 (vii) extend the Loan Commitment Period; (ix) amend, modify or waive any provision applicable to the indemnification of any Lender; (x) consent to the assignment or transfer by any Designated Entity of any of its rights or obligations under this Agreement or the other Loan Documents; or (xi) amend, modify or waive the rights and obligations of the Issuing Bank or the Agents; provided, that no obligation to any Designated Entity of any Lender or Issuing Bank or any Agent may be amended, modified or waived without the written approval of Borrower, which approval shall not be unreasonably withheld. Notwithstanding the foregoing or anything to the contrary herein or in any other Loan Document, no provision of Article 7 may be amended in any way which impacts or affects any Agent in its capacity as an Agent (as opposed to its capacity as a Lender) without the prior written consent of such Agent. Except as provided in the preceding three sentences or as expressly provided in any Loan Document, the Required Lenders may waive, modify, amend or supplement this Agreement and each of the other Loan Documents. Section 8.2 Survival of Agreements; Cumulative Nature. Each Designated Entity's various representations, warranties, covenants, indemnities and agreements in the Loan Documents shall survive the execution and delivery of this Agreement and the other Loan Documents and the performance hereof and thereof, including the making or granting of the Loans, the issuance of the Letters of Credit and the delivery of the Notes, and the other Loan Documents, and shall further survive until all of the Obligations are paid in full to Agents and Lenders, all Letters of Credit have expired or been canceled and all of Agents' and Lenders' obligations to Borrower are terminated, provided that, notwithstanding the foregoing, certain Obligations of certain Designated Entities under their respective Guaranties shall survive or be reinstated as provided in such Guaranties. The representations, warranties, indemnities, and covenants made by any Designated Entity in any Loan Documents, and the rights, powers, and privileges granted to Agents and Lenders in the Loan Documents, are cumulative. Section 8.3 Notices. All notices, requests, consents, demands and other communications required or permitted under any Loan Document shall be in writing, unless otherwise specifically provided in such Loan Document (provided that Administrative Agent may give telephonic notices to the other Agents and Lenders), and shall be deemed sufficiently given or furnished if delivered by personal delivery, by telecopy (with telephonic confirmation of transmission), by delivery service with proof of delivery, or by registered or certified United States mail, postage prepaid, to Borrower at the address of Borrower specified on the signature pages hereto and to each Agent and each Lender at their addresses specified on the 76 81 signature pages hereto (unless changed by similar notice in writing given by the particular Person whose address is to be changed). Any such notice or communication shall be deemed to have been given: (a) in the case of personal delivery or delivery service, as of the date of first attempted delivery during normal business hours at the address provided herein; (b) in the case of telecopy, upon receipt; or (c) in the case of registered or certified United States mail, three (3) days after deposit in the mail, postage prepaid; provided, however, that no Request for Advance or Rate Election shall become effective until actually received by Administrative Agent and no request for the issuance of a Letter of Credit or Letter of Credit Application shall become effective until actually received by the Issuing Bank. Section 8.4 Parties in Interest. All grants, covenants and agreements contained in the Loan Documents shall bind and inure to the benefit of the parties thereto and their respective successors and assigns; provided, however, that no Designated Entity may assign or transfer any of its rights or delegate any of its duties or obligations under any Loan Document without the prior written consent of all Lenders. Section 8.5 Governing Law. THE LOAN DOCUMENTS SHALL BE DEEMED CONTRACTS AND INSTRUMENTS MADE UNDER THE LAWS OF THE STATE OF TEXAS AND SHALL BE CONSTRUED AND ENFORCED IN ACCORDANCE WITH AND GOVERNED BY THE LAWS OF THE STATE OF TEXAS AND THE LAWS OF THE UNITED STATES OF AMERICA, WITHOUT REGARD TO PRINCIPLES OF CONFLICTS OF LAW. CHAPTER 15 OF TEXAS REVISED CIVIL STATUTES ANNOTATED ARTICLE 5069 (WHICH REGULATES CERTAIN REVOLVING CREDIT LOAN ACCOUNTS AND REVOLVING TRI-PARTY ACCOUNTS) DOES NOT APPLY TO THIS AGREEMENT OR TO THE NOTES. Section 8.6 Limitation on Interest. It is the intention of the parties hereto to conform strictly to applicable usury laws and, anything herein or any other Loan Document to the contrary notwithstanding, the obligations of Designated Entities to a Lender or an Agent under this Agreement and the Loan Documents shall be subject to the limitation that payments of interest shall not be required to the extent that receipt thereof would be contrary to provisions of law applicable to such Lender or Agent limiting rates of interest which may be charged or collected by such Lender or Agent. Accordingly, if the transactions contemplated hereby would be usurious under laws applicable to a Lender or Agent (including the federal and state laws of the United States of America or of any other jurisdiction whose laws may be mandatorily applicable to such Lender or Agent notwithstanding anything to the contrary in 77 82 this Agreement or any other Loan Document) then, in that event, notwithstanding anything to the contrary in this Agreement or any other Loan Document, it is agreed as follows: (a) the provisions of this Section shall govern and control; (b) the aggregate of all consideration which constitutes interest under applicable law that is contracted for, taken, reserved, charged or received under this Agreement, or under any of the aforesaid agreements or otherwise in connection with this Agreement or any other Loan Document by such Lender or Agent shall under no circumstances exceed the maximum amount of interest allowed by applicable law (such maximum lawful interest rate, if any, with respect to each Lender and each Agent herein called the "Maximum Lawful Rate"), and any excess shall be canceled automatically and if theretofore paid shall be credited to the relevant Designated Entity by such Lender or Agent (or, if such consideration shall have been paid in full, such excess refunded to the relevant Designated Entity); (c) all sums paid, or agreed to be paid, to such Lender or Agent for the use, forbearance and detention of the indebtedness of the relevant Designated Entity to such Lender or Agent hereunder or under any other Loan Document shall, to the extent permitted by laws applicable to such Lender or Agent, as the case may be, be amortized, prorated, allocated and spread throughout the full term of such indebtedness until payment in full so that the actual rate of interest is uniform throughout the full term thereof; (d) if at any time the interest provided pursuant to any provision of this Agreement or any other Loan Document, together with any other fees payable pursuant to this Agreement or any other Loan Document and deemed interest under laws applicable to such Lender or Agent, exceeds the amount which would have accrued at the Maximum Lawful Rate, the amount of interest and any such fees to accrue to such Lender or Agent pursuant to this Agreement or any other Loan Document shall be limited, notwithstanding anything to the contrary in this Agreement or any other Loan Document, to that amount which would have accrued at the Maximum Lawful Rate, but any subsequent reductions, as applicable, shall not reduce the interest to accrue to such Lender or Agent pursuant to this Agreement or any other Loan Document below the Maximum Lawful Rate until the total amount of interest accrued pursuant to this Agreement or such other Loan Document, as the case may be, and such fees deemed to be interest equals the amount of interest which would have accrued to such Lender or Agent if a varying rate of interest per annum equal to the interest provided pursuant to Section 2.3 or any other relevant Section hereof (other than this Section) and the Notes, as applicable, had at all times been in 78 83 effect, plus the amount of fees which would have been received but for the effect of this Section; and (e) if the total amount of interest paid by or accrued with respect to the Obligations of Borrower, together with any other fees payable pursuant to this Agreement and the other Loan Documents and deemed interest under laws applicable to such Lender or Agent pursuant to this Agreement or any other Loan Document under the foregoing provisions of this Section is less than the total amount of interest which would have accrued if a varying rate per annum equal to the interest provided pursuant to Section 2.3 or any other relevant section hereof (other than this Section), as applicable, had at all times been in effect and all fees provided for in this Agreement and the other Loan Documents had been paid, then Borrower severally agrees to pay to such Lender or Agent an amount equal to the difference between, (i) the lesser of, (x) the amount of interest and fees which would have accrued if the Maximum Lawful Rate had at all times been in effect, and (y) the amount of interest and fees which would have accrued if a varying rate per annum equal to the interest provided pursuant to Section 2.3 or such other relevant section of this Agreement (other than this Section) and the Notes, as applicable, had at all times been in effect and all fees had been paid, and (ii) the amount of interest and fees accrued in accordance with the other provisions of this Agreement and other Loan Documents. For purposes of Chapter 1D of Article 5069 of the Texas Credit Title, Title 79, Vernon's Texas Civil Statutes, as amended (formerly Article 5069-1.04, Vernon's Texas Civil Statutes, as amended), to the extent, if any, applicable to any Lender or Agent, Borrower and each other Designated Entity agrees that the Maximum Lawful Rate shall be the "applicable interest rate ceiling" as defined in said Chapter, provided that such Lender or Agent, as applicable, may also rely, to the extent permitted by applicable laws of the State of Texas and the United States of America, on alternative maximum rates of interest under other laws applicable to such Lender or Agent from time to time if greater. Section 8.7 Termination; Limited Survival. In its sole and absolute discretion, Borrower may, at any time that no Obligations or other amounts are owing and no Letters of Credit are outstanding, elect to terminate this Agreement in a written notice delivered to Administrative Agent. Upon receipt by Administrative Agent of such a notice, if no Obligations or other amounts are then owing and no Letters of Credit are outstanding, this Agreement and all other Loan Documents shall thereupon be terminated and the parties thereto released from all prospective obligations hereunder or thereunder. Notwithstanding the foregoing or anything herein to the contrary, any waivers or admissions made by any Designated Entity in any Loan Document, any Obligations under Sections 2.16 through 2.20, any obligations which any Designated Entity may have to indemnify or compensate any Agent, any Issuing Bank, or any Lender in connection with matters arising upon or prior to the 79 84 termination of this Agreement and any obligations which any Lender may have to indemnify or compensate any Agent or Issuing Bank in connection with matters arising upon or prior to the termination of this Agreement shall survive any termination of this Agreement or any other Loan Document and the release of Designated Entities. At the request and expense of Borrower, Managing Agents shall prepare and execute all necessary instruments to reflect and effect such termination of the Loan Documents including, without limitation, the Security Instruments. Managing Agents are hereby authorized, jointly and severally, to execute all such instruments on behalf of all Lenders, without the joinder of or further action or consent by any Lender. Section 8.8 Assignments; Participations. (a) Each Lender shall have the right to sell, assign or transfer all or any part of such Lender's Notes, Loans, Commitments and LC Obligations hereunder to one or more Affiliates, Lenders, financial institutions, pension plans, investment funds, or similar Persons or to a Federal Reserve Bank; provided, that in connection with each sale, assignment or transfer (other than to an Affiliate, a Lender or a Federal Reserve Bank), the applicable Lender will consider the opinion and recommendation of Borrower, which opinion and recommendation shall in no way be binding upon such Lender, and each such sale, assignment, or transfer (other than to an Affiliate, a Lender or a Federal Reserve Bank) shall be with the consent of Borrower (unless an Event of Default has occurred and is continuing), which consent will not be unreasonably withheld, and with the consent of Administrative Agent, which consent will not be unreasonably withheld, and the assignee, transferee or recipient shall have, to the extent of such sale, assignment, or transfer, the same rights, benefits and obligations as it would if it were such Lender and a holder of such Notes, Commitments and LC Obligations, including, without limitation, the right to vote on decisions requiring consent or approval of all Lenders, Majority Lenders or Required Lenders and the obligation to fund its Loans; provided further, that (1) each Lender in making each such sale, assignment, or transfer must sell, assign or transfer a pro rata portion of its Commitments and each Loan (other than a Swing Line Advance or a Competitive Bid Advance) and LC Obligation made or held by such Lender, (2) each such sale, assignment, or transfer (other than to an Affiliate, a Lender or a Federal Reserve Bank) shall be in an aggregate principal amount not less than $10,000,000, (3) each remaining Lender shall at all times maintain Commitments then outstanding in an aggregate principal amount at least equal to $10,000,000; (4) no Lender may offer to sell its Notes, Commitments, LC Obligations or Loans or interests therein in violation of any securities laws; and (5) no such assignments (other than to a Federal Reserve Bank) shall become effective until the assigning Lender delivers to Administrative Agent and Borrower copies of all written assignments and other 80 85 documents evidencing any such assignment and an Agreement to be Bound in the form of Exhibit L, providing for the assignee's ratification and agreement to be bound by the terms of this Agreement and the other Loan Documents. An assignment fee in the amount of $3,500 for each such assignment (other than to an Affiliate, a Lender or a Federal Reserve Bank) will be payable to Administrative Agent by assignor or assignee. Within five (5) Business Days after its receipt of copies of any assignment and the other documents relating thereto and the following described Notes, Borrower shall execute and deliver to Administrative Agent (for delivery to the relevant assignee) new Notes evidencing such assignee's assigned Loans and Commitments and if the assignor Lender has retained a portion of its Loans, replacement Notes in the principal amount of the Loans and Commitments retained by the assignor Lender (except as provided in the last sentence of this paragraph (a) such Notes to be in exchange for, but not in payment of, the Notes held by such Lender). On and after the effective date of an assignment hereunder, the assignee shall for all purposes be a Lender, party to this Agreement and any other Loan Document executed by the Lenders and shall have all the rights and obligations of a Lender under the Loan Documents, to the same extent as if it were an original party thereto, and no further consent or action by Borrower, Lenders or any Agent shall be required to release the transferor Lender, with respect to the Commitments, the LC Obligations and the Loans assigned to such assignee and the transferor Lender shall henceforth be so released. (b) Each Lender shall have the right to grant participations in all or any part of such Lender's Notes, Commitments, LC Obligations, and Loans hereunder to one or more pension plans, investment funds, financial institutions or other Persons; provided, that: (1) each Lender granting a participation shall retain the right to vote hereunder, and no participant shall be entitled to vote hereunder on decisions requiring consent or approval of Lenders, Majority Lenders or Required Lenders (except as set forth in (3) below); (2) in the event any Lender grants a participation hereunder, such Lender's obligations under the Loan Documents shall remain unchanged, such Lender shall remain solely responsible to the other parties hereto for the performance of such obligations, such Lender shall remain the holder of any such Notes for all purposes under the Loan Documents, and each Agent, each Lender and Borrower shall be entitled to deal with the Lender granting a participation in the same manner as if no participation had been granted; and 81 86 (3) no participant shall ever have any right by reason of its participation to exercise any of the rights of Lenders hereunder, except that any Lender may agree with any participant that such Lender will not, without the consent of such participant (which consent may not be unreasonably withheld), consent to any amendment or waiver described in Section 8.1 requiring approval of 100% of the Lenders. (c) It is understood and agreed that any Lender may provide to assignees and participants and prospective assignees and participants financial information and reports and data concerning Borrower's properties and operations which was provided to such Lender pursuant to this Agreement, subject to Section 8.9. (d) Upon the reasonable request of either of the Managing Agents or Borrower, each Lender will identify those to whom it has assigned or participated any part of its Notes, LC Obligations or Loans, and provide the amounts so assigned or participated. Section 8.9 Confidentiality. Each Agent and each Lender agrees that it (a) will maintain the confidentiality of all non-public information from any Designated Entity or any Subsidiary of Borrower obtained pursuant to the terms of this Agreement or any other Loan Document in accordance with safe and sound banking practices, and (b) will not use such confidential information for any purpose other than in connection with this Agreement; provided, however, that this restriction shall not apply to information which (w) has at the particular time in question entered the public domain, or been independently developed without the use or incorporation of any non-public information provided to such Agent or Lender by any Designated Entity or any Subsidiary of Borrower by such Agent or such Lender other than through disclosure by such Agent or such Lender in violation of this Section, (x) is required to be disclosed by law or by any order, rule, regulation or legal process (whether valid or invalid) of any court or Governmental Authority, (y) is furnished to any other Lender or to any purchaser or prospective purchaser of participations, assignments or other interests in any Loan, Note, LC Obligation or Commitment that has executed and delivered to Borrower an agreement containing terms substantially similar to this Section and reasonably acceptable to Borrower, to keep such information confidential or (z) is disclosed to such Lender's or Agent's examiners, Affiliates, outside auditors, counsel and other professional advisors who have a need for such information in connection with this Agreement and who are advised of the confidential nature of such information. As used in this Section, the terms "Agent" and "Lender" shall refer not only to the Persons designated as such in Section 1.1, but also to each director, Affiliate, officer, agent, attorney, employee and representative of such Person. Notwithstanding any other provisions of this Agreement, the terms of this Section shall survive the termination of this Agreement for a period of three (3) years. 82 87 Section 8.10 Severability. If any term or provision of any Loan Document shall be determined to be illegal or unenforceable in any jurisdiction, such term or provision shall, as to such jurisdiction, be illegal or unenforceable, without affecting the remaining provisions in that jurisdiction or the legality or enforceability of such terms or conditions in any other jurisdiction. Section 8.11 Counterparts. This Agreement may be separately executed in any number of counterparts and by different parties hereto in separate counterparts, each of which when so executed shall be deemed to constitute one and the same Agreement. Section 8.12 WAIVER OF JURY TRIAL, PUNITIVE DAMAGES. EACH OF THE BORROWER, AGENTS AND LENDERS HEREBY (I) IRREVOCABLY WAIVES, TO THE MAXIMUM EXTENT NOT PROHIBITED BY LAW, ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION DIRECTLY OR INDIRECTLY AT ANY TIME ARISING OUT OF, UNDER OR IN CONNECTION WITH THE LOAN DOCUMENTS OR ANY TRANSACTION CONTEMPLATED THEREBY OR ASSOCIATED THEREWITH, BEFORE OR AFTER MATURITY; (II) IRREVOCABLY WAIVES, TO THE MAXIMUM EXTENT NOT PROHIBITED BY LAW, ANY RIGHT IT MAY HAVE TO CLAIM OR RECOVER IN ANY SUCH LITIGATION ANY EXEMPLARY, PUNITIVE OR CONSEQUENTIAL DAMAGES; (III) CERTIFIES THAT NO PARTY HERETO NOR ANY REPRESENTATIVE OR AGENT OR COUNSEL FOR ANY PARTY HERETO HAS REPRESENTED, EXPRESSLY OR OTHERWISE, OR IMPLIED THAT SUCH PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVERS; AND (IV) ACKNOWLEDGES THAT IT HAS BEEN INDUCED TO ENTER INTO THIS AGREEMENT, THE OTHER LOAN DOCUMENTS AND THE TRANSACTIONS CONTEMPLATED HEREBY AND THEREBY BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS CONTAINED IN THIS SECTION. Section 8.13 Several Obligations. The respective obligations of Lenders hereunder are several and not joint and no Lender shall be the partner or agent of any other (except to the extent to which an Agent is authorized to act as such). The failure of any Lender to perform any of its obligations hereunder shall not relieve any other Lender from any of its obligations hereunder. This Agreement is not intended to, and shall not be construed so as to, confer any right or benefit upon any Person other than the parties to this Agreement and their respective successors and assigns. Section 8.14 Nonliability of Lenders. The relationship between Borrower on the one hand and Lenders and Agents on the other hand shall be solely that of borrower and lender. None of the Agents nor any Lender shall have any fiduciary responsibilities to Borrower or any of its respective Subsidiaries. None of the Agents nor any Lender undertakes 83 88 any responsibility to Borrower or any of their respective Subsidiaries to review or inform Borrower of any matter in connection with any phase of Borrower's or such Subsidiary's business or operations. Section 8.15 Setoff. In addition to, and without any limitation of, any rights of the Lenders under applicable law, if Borrower becomes insolvent, however evidenced, or any Event of Default or Default occurs and the maturity of the Obligations has been accelerated, any indebtedness from any Lender to Borrower (including all account balances, whether provisional or final and whether or not collected or available) may be offset and applied toward the payment of the Obligations owing to such Lender, whether or not the Obligations, or any part thereof, shall then be due and payable.

SECTION 8.17 FORUM SELECTION AND CONSENT TO JURISDICTION. ANY LITIGATION BASED HEREON, OR ARISING OUT OF, UNDER, OR IN CONNECTION WITH, THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT, OR ANY COURSE OF CONDUCT, COURSE OF DEALING, STATEMENTS (WHETHER VERBAL OR WRITTEN) OR ACTIONS OF THE AGENTS, THE LENDERS OR THE BORROWER SHALL BE BROUGHT AND MAINTAINED EXCLUSIVELY IN THE COURTS OF THE STATE OF TEXAS OR IN THE UNITED STATES DISTRICT COURT FOR THE NORTHERN DISTRICT OF TEXAS; PROVIDED, HOWEVER, THAT ANY SUIT SEEKING ENFORCEMENT AGAINST ANY COLLATERAL OR OTHER PROPERTY MAY BE BROUGHT, AT THE COLLATERAL AGENT'S OPTION, IN THE COURTS OF ANY JURISDICTION WHERE SUCH COLLATERAL OR OTHER PROPERTY MAY BE FOUND.

SECTION 2.4. Reinstatement. Guarantor agrees that this Guaranty shall continue to be effective or be reinstated, as the case may be, if at any time any payment (in whole or in part) of any of the Obligations guaranteed hereby is rescinded or must otherwise be restored by any Lender Party or any holder of any Note, any LC Application or any interest in an LC Obligation, upon the insolvency, bankruptcy or reorganization of Borrower, or any other Designated Entity or otherwise, all as though such payment had not been made. SECTION 2.5. Waiver. Guarantor hereby waives promptness, diligence, presentment, notice of acceptance and any other notice with respect to any of the Obligations of Borrower or any other Designated Entity and this Guaranty and any requirement that any Agent, any other Lender Party or any holder of any Note, any LC Application, any Letter of Credit or any interest therein protect, secure, perfect or insure any security interest or Lien, Exhibit B - 6 130 or any property subject thereto, or exhaust any right or take any action against Borrower, any other Designated Entity or any other Person (including any other guarantor) or entity or any collateral securing the Obligations of Borrower or any other Designated Entity, as the case may be. SECTION 2.6. Waiver of Subrogation. Guarantor hereby irrevocably waives any claim or other rights which it may now or hereafter acquire against Borrower or any other Designated Entity that arise from the existence, payment, performance or enforcement of Guarantor's obligations under this Guaranty or any other Loan Document, including any right of subrogation, reimbursement, contribution, exoneration, or indemnification, any right to participate in any claim or remedy of the Lender Parties against Borrower or any other Designated Entity or any collateral which the Collateral Agent now has or hereafter acquires, whether or not such claim, remedy or right arises in equity, or under contract, statute or common law, including the right to take or receive from Borrower or any other Designated Entity, directly or indirectly, in cash or other property or by set-off or in any manner, payment or security on account of such claim or other rights. If any amount shall be paid to Guarantor in violation of the preceding sentence and the Obligations shall not have been paid in cash in full and the Commitments have not been terminated, such amount shall be deemed to have been paid to Guarantor for the benefit of, and held in trust for, the Lender Parties, and shall forthwith be paid to the Lender Parties to be credited and applied upon the Obligations, whether matured or unmatured; otherwise it shall be returned to remitter. Guarantor acknowledges that it will receive direct and indirect benefits from the financing arrangements contemplated by the Credit Agreements and that the waiver set forth in this Section is knowingly made in contemplation of such benefits.

Guarantor hereby agrees that: (a) If, for the purposes of obtaining judgment in any court, it is necessary to convert a sum due hereunder in United States Dollars into another currency, Guarantor agrees, to the fullest extent permitted by law, that the rate of exchange used shall be that at which in accordance with normal banking procedures the Administrative Agent could purchase United States Dollars with such other currency on the Business Day preceding that on which final judgment is given. (b) The obligation of Guarantor in respect of any sum due from it to any Lender Party or any holder of a Note hereunder shall, notwithstanding any judgment in a currency other than United States Dollars, be discharged only to the extent that on the Business Day following receipt by such Lender Party or such holder, as the case may be, of any sum adjudged to be so due in such other currency such Lender Party or such holder, as the case may be, may, in accordance with normal banking procedures, purchase United States Dollars with such other currency; in the event that the United States Dollars so purchased are less than the sum originally due to such Lender Party in United States Dollars, Guarantor, as a separate obligation and notwithstanding any such judgment, hereby indemnifies and holds harmless such Lender Party and such holder against such loss, and if the United States Dollars so purchased exceed the sum originally due to such Lender Party or such holder in United States Dollars, such Lender Party or such holder, as the case may be, shall remit to Guarantor such excess.] Exhibit B - 10 134 ARTICLE III REPRESENTATIONS AND WARRANTIES SECTION 3.1.

SECTION 2.6. Security Interest Absolute. All rights of Collateral Agent and the security interests granted to Collateral Agent hereunder, and all obligations of Pledgor hereunder, shall be absolute and unconditional, irrespective of (a) any lack of validity or enforceability of the Credit Agreements, any Note or any other Loan Document, (b) the failure of any Lender Party or any holder of any Note, (i) to assert any claim or demand or to enforce any right or remedy against Borrower, any other Exhibit M - 7 169 Designated Entity or any other Person under the provisions of the Credit Agreements, any Note, any other Loan Document or otherwise, or (ii) to exercise any right or remedy against any other guarantor of, or collateral securing, any Obligations of Borrower or any other Designated Entity, (c) any change in the time, manner or place of payment of, or in any other term of, all or any of the Obligations or any other extension, compromise or renewal of any Obligation of Borrower or any other Designated Entity, (d) any reduction, limitation, impairment or termination of any Obligations of Borrower or any other Designated Entity for any reason, including any claim of waiver, release, surrender, alteration or compromise, and shall not be subject to (and Pledgor hereby waives any right to or claim of) any defense or setoff, counterclaim, recoupment or termination whatsoever by reason of the invalidity, illegality, nongenuineness, irregularity, compromise, unenforceability of, or any other event or occurrence affecting, any Obligations of Borrower, any other Designated Entity or otherwise, (e) any amendment to, rescission, waiver, or other modification of, or any consent to departure from, any of the terms of the Credit Agreements, any Note or any other Loan Document, (f) any addition, exchange, release, surrender or non-perfection of any collateral (including the Collateral), or any amendment to or waiver or release of or addition to or consent to departure from any guaranty, for any of the Obligations, or (g) any other circumstances which might otherwise constitute a defense available to, or a legal or equitable discharge of, Borrower, any other Designated Entity, any surety or any guarantor. SECTION 2.7. Waiver of Subrogation. Pledgor hereby irrevocably waives any claim or other rights which it may now or hereafter acquire against Borrower or any other Designated Entity that arise from the existence, payment, performance or enforcement of Pledgor's obligations under this Pledge Agreement or any other Loan Document, including any right of subrogation, reimbursement, exoneration, or indemnification, any right to participate in any claim or remedy of Lender Parties against Borrower or any other Designated Entity or any collateral which Collateral Agent now has or hereafter acquires, whether or not such claim, remedy or right arises in equity, or under contract, statute or common law, including the right to take or receive from Borrower or any other Designated Entity, directly or indirectly, in cash or other property or by set-off or in any manner, payment or security on account of such claim or other rights. If any amount shall be paid to Pledgor in violation of the preceding sentence and the Obligations shall not have been paid in cash in full and the Commitments have not been terminated, such amount shall be deemed to have been paid to Pledgor for the benefit of, and held in trust for, Lender Parties, and shall forthwith be paid to Lender Parties to be credited and applied upon the Obligations, whether matured or Exhibit M - 8 170 unmatured. Pledgor acknowledges that it will receive direct and indirect benefits from the financing arrangements contemplated by the Credit Agreements and that the waiver set forth in this Section is knowingly made in contemplation of such benefits. ARTICLE III REPRESENTATIONS AND WARRANTIES SECTION 3.1.

SECTION 3.1.3. Valid Security Interest.

In the case of any Pledged Shares constituting such Collateral, all of such Pledged Shares are duly authorized and validly issued, fully paid, and non-assessable, and constitute 65% of the issued and outstanding shares of capital stock of each Pledged Share Issuer owned by Pledgor set forth across from the name of such Pledged Share Issuer on Attachment 1 hereto.

ARTICLE IV COVENANTS SECTION 4.1. Protect Collateral; Further Assurances, etc. Pledgor will not sell, assign, transfer, pledge, or encumber in any other manner the Collateral (except in favor of Collateral Agent hereunder). Pledgor will warrant and defend the right and title herein granted unto Collateral Agent in and to the Collateral (and all right, title and interest represented by the Collateral) against the claims and demands of all Persons whomsoever. Pledgor agrees that at any time, and from time to time, at the expense of Pledgor, Pledgor will promptly execute and deliver all further instruments, and take all further action, that may be necessary or desirable, or that Collateral Agent may reasonably request, in order to perfect and protect any security interest granted or purported to be granted hereby or to enable Collateral Agent to exercise and enforce its rights and remedies hereunder with respect to any Collateral. Pledgor shall provide Collateral Agent with copies of all written information received from any securities intermediary of Pledgor with respect to any Collateral. SECTION 4.2. Stock Powers, etc. Pledgor agrees that all Pledged Shares (and all other shares of capital stock constituting Collateral) delivered by Pledgor pursuant to this Pledge Agreement will be accompanied by duly indorsed undated blank stock powers, in substantially the form of Attachment 2 hereto, or other equivalent instruments of transfer acceptable to Collateral Agent. Pledgor will, from time to time upon the request of Collateral Agent, promptly deliver to Collateral Agent such stock powers, in substantially the form of Attachment 2, instruments and similar documents, satisfactory in form and substance to Collateral Agent, with respect to the Collateral as Collateral Agent may reasonably request and will, from time to time upon the request of Collateral Agent after the occurrence of any Event of Default, promptly transfer any Pledged Shares or other shares of common stock constituting Collateral into the name of any nominee designated by Collateral Agent. SECTION 4.3. Continuous Pledge. Subject to Section 2.4, the Pledgor will, at all times, keep pledged to Collateral Agent pursuant hereto all Pledged Shares, all other shares of capital stock constituting Collateral, and all securities, security entitlements and securities accounts constituting Collateral and all other Collateral and other securities, instruments, security entitlements, financial assets, investment property, proceeds, Exhibit M - 10 172 and rights from time to time received by or distributable to Pledgor in respect of any Collateral. SECTION 4.4. Dividends, etc. Pledgor agrees after any acceleration under the Credit Agreements or Default occurring on the Maturity Date, promptly upon receipt thereof by Pledgor and without any request therefor by Collateral Agent, to deliver (properly endorsed where required hereby or requested by Collateral Agent) to Collateral Agent all Dividends, Distributions, all interest, all principal, all other cash payments, and all proceeds of the Collateral, all of which shall be held by Collateral Agent as additional Collateral for use in accordance with Section 6.3. All Dividends, Distributions, interest, principal, cash payments, and proceeds which may at any time and from time to time be held by Pledgor but which Pledgor is then obligated to deliver to Collateral Agent, shall, until delivery to Collateral Agent, be held by Pledgor separate and apart from its other property in trust for Collateral Agent. SECTION 4.5. Additional Undertakings. Pledgor will not, without the prior written consent of Collateral Agent, take or omit to take any action the taking or the omission of which would result in any impairment or alteration of the security interest in the Pledged Shares. ARTICLE V COLLATERAL AGENT SECTION 5.1. Agent Appointed Attorney-in-Fact. Pledgor hereby irrevocably appoints Collateral Agent Pledgor's attorney-in-fact, with full authority in the place and stead of Pledgor and in the name of Pledgor or otherwise, from time to time in Collateral Agent's discretion, to take any action and to execute any writing or paper which Collateral Agent may deem necessary or advisable to accomplish the purposes of this Pledge Agreement, including without limitation: (a) after the occurrence and continuance of an Event of Default, to ask, demand, collect, sue for, recover, compromise, receive and give acquittance and receipts for moneys due and to become due under or in respect of any of the Collateral; (b) to receive, endorse, and collect any drafts or other instruments, documents and chattel paper, in connection with clause (a) above; and (c) to file any claims or take any action or institute any proceedings which Collateral Agent may deem necessary or desirable for the collection of any of the Collateral or otherwise to enforce the rights of Collateral Agent with respect to any of the Collateral. Pledgor hereby acknowledges, consents and agrees that the power of attorney granted pursuant to this Section is irrevocable and coupled with an interest. Exhibit M - 11 173 SECTION 5.2. Agent May Perform. If Pledgor fails to perform any agreement contained herein, Collateral Agent may itself perform, or cause performance of, such agreement, and the expenses of Collateral Agent incurred in connection therewith shall be payable by Pledgor pursuant to Section 6.4. SECTION 5.3. Agent Has No Duty. The powers conferred on Collateral Agent hereunder are solely to protect its interest (on behalf of Lender Parties) in the Collateral and shall not impose any duty on it to exercise any such powers. Except for reasonable care of any Collateral in its possession and the accounting for moneys actually received by it hereunder, Collateral Agent shall have no duty as to any Collateral or responsibility for (a) ascertaining or taking action with respect to calls, conversions, exchanges, maturities, tenders or other matters relative to any Pledged Shares, whether or not Collateral Agent has or is deemed to have knowledge of such matters or (b) taking any necessary steps to preserve rights against prior parties or any other rights pertaining to any Collateral. SECTION 5.4. Reasonable Care. Collateral Agent is required to exercise reasonable care in the custody and preservation of any of the Collateral in its possession; provided, however, Collateral Agent shall be deemed to have exercised reasonable care in the custody and preservation of any of the Collateral, if it takes such action for that purpose as Pledgor reasonably requests in writing at times other than upon the occurrence and during the continuance of any Event of Default, but failure of Collateral Agent to comply with any such request at any time shall not in itself be deemed a failure to exercise reasonable care. ARTICLE VI REMEDIES SECTION 6.1. Certain Remedies. On or after any acceleration under the Credit Agreements or Default occurring on the Maturity Date: (a) Collateral Agent may exercise in respect of the Collateral, in addition to other rights and remedies provided for herein or otherwise available to it, all the rights and remedies of a secured party on default under the U.C.C. (whether or not the U.C.C. applies to the affected Collateral) and also may, without notice except as specified below, sell the Collateral or any part thereof in one or more parcels at public or private sale, at any of Collateral Agent's offices or elsewhere, for cash, on credit or for future delivery, and upon such other terms as Collateral Agent may deem commercially reasonable. Pledgor agrees that, to the extent notice of sale shall be required by law, Exhibit M - 12 174 at least ten days' prior notice to Pledgor of the time and place of any public sale or the time after which any private sale is to be made shall constitute reasonable notification. Collateral Agent shall not be obligated to make any sale of Collateral regardless of notice of sale having been given. Collateral Agent may adjourn any public or private sale from time to time by announcement at the time and place fixed therefor, and such sale may, without further notice, be made at the time and place to which it was so adjourned. (b) Collateral Agent may (i) transfer all or any part of the Collateral into the name of Collateral Agent or its nominee, with or without disclosing that such Collateral is subject to the lien and security interest hereunder, (ii) notify the parties obligated on any of the Collateral to make payment to Collateral Agent of any amount due or to become due thereunder, (iii) enforce collection of any of the Collateral by suit or otherwise, and surrender, release or exchange all or any part thereof, or compromise or extend or renew for any period (whether or not longer than the original period) any obligations of any nature of any party with respect thereto, (iv) endorse any checks, drafts, or other writings in Pledgor's name to allow collection of the Collateral, (v) take control of any proceeds of the Collateral, and (vi) execute (in the name, place and stead of Pledgor) endorsements, assignments, stock powers and other instruments of conveyance or transfer with respect to all or any of the Collateral. SECTION 6.2. Compliance with Restrictions. Pledgor agrees that in any sale of any of the Collateral whenever an Event of Default shall have occurred and be continuing, Collateral Agent is hereby authorized to comply with any limitation or restriction in connection with such sale as it may be advised by counsel is necessary in order to avoid any violation of applicable law (including compliance with such procedures as may restrict the number of prospective bidders and purchasers, require that such prospective bidders and purchasers have certain qualifications, and restrict such prospective bidders and purchasers to persons who will represent and agree that they are purchasing for their own account for investment and not with a view to the distribution or resale of such Collateral), or in order to obtain any required approval of the sale or of the purchaser by any governmental regulatory authority or official, and Pledgor further agrees that such compliance shall not result in such sale being considered or deemed not to have been made in a commercially reasonable manner, nor shall Collateral Agent be liable nor accountable to Pledgor for any discount allowed by the reason of the fact that such Collateral is sold in compliance with any such limitation or restriction. Exhibit M - 13 175 SECTION 6.3. Application of Proceeds. All cash proceeds received by Collateral Agent in respect of any sale of, collection from, or other realization upon, all or any part of the Collateral may, in the discretion of Collateral Agent, be held by Collateral Agent as additional collateral security for, or then or at any time thereafter be applied (after payment of any amounts payable to Collateral Agent pursuant to Sections 6.4 of the Credit Agreements) in whole or in part by Collateral Agent against, all or any part of the Secured Obligations in such order as Collateral Agent shall elect. Any surplus of such cash or cash proceeds held by Collateral Agent and remaining after payment in full of all the Secured Obligations, and the termination of all Commitments, shall be paid over to Pledgor or to whomsoever may be lawfully entitled to receive such surplus. SECTION 6.4. Indemnity and Expenses. Pledgor hereby indemnifies and holds harmless Collateral Agent in accordance with Sections 6.4 of the Credit Agreements.

SECTION 7.3. Protection of Collateral. Collateral Agent may from time to time, at its option, perform any act which Pledgor agrees hereunder to perform and which Pledgor shall fail to perform after being requested in writing so to perform after the occurrence and continuance of an Event of Default and Collateral Agent may from time to time take any other action which Collateral Agent reasonably deems necessary for the maintenance, preservation or protection of any of the Collateral or of its security interest therein. SECTION 7.4. Obligations Not Affected. The obligations of Pledgor under this Pledge Agreement shall remain in full force and effect without regard to, and shall not be impaired or affected by: Exhibit M - 14 176 (a) any amendment or modification or addition or supplement to the Credit Agreements, any Note, any other Loan Documents, any instrument delivered in connection therewith, or any assignment or transfer thereof; (b) any exercise, non-exercise, or waiver by Collateral Agent or any Lender of any right, remedy, power, or privilege under or in respect of, or any release of any guaranty or collateral provided pursuant to, this Pledge Agreement, the Credit Agreements, Pledgor's Guaranty or any other Loan Document; (c) any waiver, consent, extension, indulgence, or other action or inaction in respect of this Pledge Agreement, the Credit Agreements, Pledgor's Guaranty or any other Loan Document or any assignment or transfer of any thereof; or (d) any bankruptcy, insolvency, reorganization, arrangement, readjustment, composition, liquidation, or the like, of Pledgor or any other Person, whether or not Pledgor shall have notice or knowledge of any of the foregoing.

The remedies herein provided are cumulative and not exclusive of any remedies provided by law. Exhibit M - 15 177 SECTION 7.7. Section Captions.

Each election by Borrower of a Tranche shall: 20 25 (a) Be made in writing in the form and substance of Exhibit D attached hereto, duly completed, herein called a "Rate Election"; (b) Specify the aggregate amount of the Loans which Borrower desires to designate as such Tranche, the first day of the Eurodollar Interest Period which is to apply thereto, and the length of such Eurodollar Interest Period; and (c) Be received by Administrative Agent not later than 10:00 a.m., Dallas, Texas time, on the third Business Day preceding the first day of the specified Eurodollar Interest Period. Promptly after receiving any such Rate Election which meets the requirements of this Section, Administrative Agent shall notify each Lender thereof. Each Rate Election shall be irrevocable. Borrower may not make any Rate Election which does not specify an Eurodollar Interest Period complying with the definition of "Eurodollar Interest Period" in Section 1.1, and the aggregate amount of the Tranche elected in any Rate Election must be $10,000,000 or a higher integral multiple of $1,000,000. Upon the termination of each Eurodollar Interest Period the portion of each Loan within the related Tranche shall, unless the subject of a new Rate Election then taking effect, automatically become a part of the Base Rate Portion of such Loan and become subject to all provisions of the Loan Documents governing such Base Rate Portion. Borrower shall have no more than fifteen (15) Tranches in effect at any time. If requested to do so by Borrower through Administrative Agent at least two (2) Business Days before the delivery date of any proposed Rate Election, each Lender will advise Administrative Agent before 10:00 a.m., Dallas, Texas time, on the Business Day following receipt of such request as to whether, if Borrower selects a specified duration of nine (9) or twelve (12) months for the Eurodollar Interest Period applicable to such proposed Rate Election, such Lender expects that deposits in dollars with a corresponding term will be available to it in the relevant market on the first day of such Eurodollar Interest Period in the amount required to fund the Eurodollar Portion of its Loan to which such Eurodollar Interest Period would apply. Unless a Lender responds by such time to the effect that it expects such deposits will be available to it, Borrower shall not be entitled to select such proposed duration for such Eurodollar Interest Period. Each Lender may, if it so elects, fulfill its obligation to fund any Eurodollar Portion by causing one of its foreign branches or Affiliates (or an international banking facility created by such Lender) to fund or continue such Eurodollar Portion; provided, however, that such Eurodollar Portion shall be deemed to have been made and held by such Lender, and the obligations of the subject Borrower to repay such Eurodollar Portion shall nevertheless be to such Lender for the account of such branch, or Affiliate (or international banking facility). In addition, Borrower hereby consents and agrees that, for purposes of any determination to be made for purposes of Sections 2.17, 2.18, 2.19 and 2.20, it shall be conclusively assumed that such Lender elected to fund all Eurodollar Portions by purchasing Dollar deposits in the interbank eurodollar market of its designated office. 21 26 Section 2.4 Swing Line Advances. In addition to borrowings pursuant to Section 2.1(a) or Section 2.22, Borrower may request Swing Line Lender to make advances to Borrower on any Business Day (unless Borrower and Swing Line Lender agree otherwise) during the Loan Commitment Period as provided in Sections 2.5 and 2.6 (herein called "Swing Line Advances"); provided, however, that (a) at no time shall the outstanding aggregate principal amount of all Swing Line Advances under this Agreement plus all "Swing Line Advances" (as defined in the Primary Credit Facility), if any, outstanding under the Primary Credit Facility exceed $50,000,000, and (b) at no time shall the sum of (1) the outstanding aggregate principal amount of all Swing Line Advances to Borrower, (2) the outstanding aggregate principal amount of the Revolving Loans, and (3) the outstanding aggregate principal amount of all Competitive Bid Advances, exceed the Facility Amount. Section 2.5 Procedure for Swing Line Advances. (a) No later than 11:00 a.m., Dallas, Texas time, on a Business Day on which Borrower desires a Swing Line Advance, Borrower shall transmit to Swing Line Lender) and to Administrative Agent by telecopy a notice in substantially the form of Exhibit E attached hereto (herein called a "Request for Swing Line Loan"). Swing Line Lender will specify the rate of interest per annum which will be the fixed rate of interest to be charged for such Swing Line Advance until maturity (herein called the "Swing Line Rate"). (b) Swing Line Lender shall wire the Swing Line Advance in immediately available funds by no later than 1:00 p.m., Dallas, Texas time on the date of request for Swing Line Advance, on such day to Administrative Agent, which shall deposit such funds to an account designated by Borrower by no later than 1:15 p.m. on the same day. (c) Borrower shall repay each such Swing Line Advance on or before 1:00 p.m., Dallas, Texas time, on the following Business Day or at such other maturity (such date of maturity being no more than fourteen (14) days after the date of the Swing Line Advance and no later than the Maturity Date) as is agreed to by Borrower, Administrative Agent and the Swing Line Lender. The repayment shall be paid on such date by Borrower (which payment may be in the form of a Swing Line Advance advanced to Borrower on that day) to Administrative Agent in immediately available funds with instructions to Administrative Agent to forward such proceeds to the Swing Line Lender. Any accrued and unpaid interest pursuant to Swing Line Advances shall be paid by Borrower (which payment may be in the form of a Swing Line Advance advanced to Borrower on that day) to Administrative Agent in immediately available funds on the first Business Day of each calendar month with instructions to Administrative Agent to forward such proceeds to the Swing Line Lender. (d) Interest on the Swing Line Advances shall be computed on the basis of a year of 365 or 366 days and actual days elapsed (including the first day, but excluding the 22 27 last day) occurring in the period for which payable and shall not exceed Maximum Lawful Rate. Past due principal and interest (to the extent allowed by law) shall bear interest at the lesser of the Default Rate or the Maximum Lawful Rate and shall be payable on demand. (e) The Swing Line Advances made by the Swing Line Lender shall be evidenced by a single promissory note of Borrower payable to the order of the Swing Line Lender in the amount of $50,000,000 and in substantially the form of Exhibit A-2 attached hereto, with appropriate insertions (herein called a "Swing Line Note"). The date, amount, Swing Line Rate and maturity of each Swing Line Advance made by a Lender to Borrower, and each payment made on account of the principal thereof, shall be recorded by such Lender on its books. (f) The Swing Line Advances will be used by Borrower to provide working capital for the operations of Borrower and its Subsidiaries and for general business purposes. No Swing Line Advances shall be used for the purpose of purchasing or carrying any Margin Stock in violation of the Margin Regulations. (g) The obligation of the Swing Line Lender to make each Swing Line Advance after timely acceptance by Borrower is further subject to the conditions contained in Article 3. Section 2.6 (a) Special Provisions for Swing Line Advances. Lenders to Make Revolving Loan Advances. (i) Swing Line Lender, at any time in its discretion, upon written request to Lenders through Administrative Agent (with a copy to Borrower), may require each Lender (including the Swing Line Lender) to make a Revolving Loan Advance, subject to the provisions of Section 2.1 hereof, in an amount equal to such Lender's Percentage Share of the outstanding Swing Line Advances. Swing Line Lender shall deliver such request to Administrative Agent prior to 11:00 a.m., Dallas, Texas time, on the Business Day next preceding the date (which shall be a Business Day) on which such Revolving Loan Advances are to be made. Promptly upon receipt of any such request, Administrative Agent shall give notice thereof to Lenders. Each Lender shall make available its Percentage Share of such Revolving Loans to Administrative Agent by 11:00 a.m., Dallas, Texas time, on the requested date for such Revolving Loan Advances. Administrative Agent shall apply the proceeds of such Revolving Loan Advances to prepay the Swing Line Advances of the Swing Line Lender; provided, however, that Administrative Agent shall be obligated to make the proceeds of such Revolving Loans available only to the extent received by it from Lenders. All Revolving Loans made pursuant to this subsection shall be Base Rate Loans. (ii) In the event Administrative Agent advances proceeds of any Revolving Loan to Swing Line Lender and one or more of the Lenders (other than Swing Line Lender) fail to fund all or any portion of such Revolving Loan Advance immediately upon receipt of 23 28 notice from Administrative Agent, then (I) such Lender shall pay directly to Administrative Agent the amount thereof together with interest thereon at the Federal Funds Rate, and (II) if not paid by such Bank, the Swing Line Lender will repay directly to Administrative Agent such amount as will equal the amount such other Lender(s) failed to fund, together with interest at the Federal Funds Rate. (b) Participations in Swing Line Advances. (i) If, at any time prior to the making of Revolving Loans pursuant to subsection 2.6(a)(i) hereof, any Event of Default described in Sections 6.1(h) hereof shall have occurred, each Lender, on the date such Revolving Loan Advance was to have been made or, if no request for Revolving Loan Advances had been made pursuant to Section 2.6(a)(i) hereof, promptly upon request by the Swing Line Lender delivered to Administrative Agent, shall purchase an undivided participation interest in all outstanding Swing Line Advances in an amount equal to its Percentage Share times the outstanding amount of such Swing Line Advances. Each Lender (other than the Swing Line Lender) will transfer immediately to Administrative Agent for credit to Swing Line Lender, in immediately available funds, the amount of its participation. Upon receipt thereof, the Swing Line Lender will deliver to such other Lender a Swing Line Advance Participation Certificate, dated the date of receipt of such funds and in the amount of such Lender's participation. (ii) Whenever, at any time after the Swing Line Lender has received from any other Lender such other Lender's participating interest in a Swing Line Advance, the Swing Line Lender receives any payment on account thereof, Administrative Agent will distribute to such other Lender its participating interest in such amount (appropriately adjusted, in the case of interest payments, to reflect the period of time during which such Lender's participating interest was outstanding and funded); provided, however, that in the event that any payment received by Swing Line Lender is required to be returned, such other Lender will return to Swing Line Lender any portion thereof previously distributed to it. (c) Acknowledged Privity. Borrower expressly agrees that, in respect of each Lender's funded participation interest in any Swing Line Advance, such Lender shall be deemed to be in privity of contract with Borrower and have the same rights and remedies against Borrower under the Loan Documents as if such funded participation interest in such Swing Line Advance were a Revolving Loan. (d) Unconditional Obligation. Each Lender's obligation to make Revolving Loan Advances or to purchase participation interests in Swing Line Advances as provided in this Section shall be absolute and unconditional and shall not be affected by any circumstance, including without limitation, (A) any set-off, counterclaim, recoupment, defense or other right which such Lender may have against Swing Line Lender, Borrower or any other Person for any reason whatsoever, (B) the existence of any Default or Event of Default at any time, (C) the occurrence of any event or existence of any condition that might have a Material Adverse Effect, or (D) any other circumstance, happening or event whatsoever, whether or not similar to any of the foregoing. 24 29 Section 2.7 Facility Fee; Amendment Fee. In consideration of each Lender's commitment to make Revolving Loan Advances and Competitive Bid Advances, Borrower will pay, or cause the payment, to Administrative Agent for the account of each Lender an annual facility fee payable to each Lender determined by applying the Facility Fee Rate to such Lender's Percentage Share of the Facility Amount as of the date of such payment, payable in arrears quarterly until the Maturity Date, with the first payment thereof to be January 1, 1998, subsequent payments on the first day following each successive calendar quarter ending on each March, June, September and December, and the final payment thereof on the Maturity Date. Borrower will pay, or cause the payment, to Administrative Agent for the account of each Lender a non-refundable amendment fee payable to each Lender determined by applying the Amendment Fee Rate to such Lender's Percentage Share of the Facility Amount as of the Effective Date. Section 2.8 Managing Agents' Fees. In addition to all other amounts due to the Managing Agents under the Loan Documents, Borrower will pay the non-refundable annual fees set forth in those certain Fee Letters dated June 25, 1997. Section 2.9 Termination and Reduction of Commitments. (a) Unless previously terminated, the Commitments shall terminate on the Maturity Date. (b) Borrower may at any time terminate, or from time to time reduce, the Commitments; provided that (i) each reduction of the Commitments shall be in an amount that is an integral multiple of $1,000,000 and not less than $5,000,000 and (ii) Borrower shall not terminate or reduce the Commitments if, after giving effect to any concurrent prepayment of the Loans in accordance with Section 2.10, the sum of (i) all Lenders' Revolving Loan Advances (including any Revolving Loan Advances to be made but not yet made pursuant to a Request for Advance) outstanding at any time plus (ii) all Swing Line Advances to Borrower plus (iii) all Lenders' Competitive Bid Advances outstanding at such time, would exceed the total Commitments. (c) Borrower shall notify the Administrative Agent of any election to terminate or reduce the Commitments under paragraph (b) of this Section at least two Business Days prior to the effective date of such termination or reduction, specifying such election and the effective date thereof. Promptly following receipt of any notice, the Administrative Agent shall advise the Lenders of the contents thereof. Each notice delivered by Borrower pursuant to this Section shall be irrevocable; provided that a notice of termination of the Commitments delivered by Borrower may state that such notice is conditioned upon the effectiveness of other credit facilities, in which case such notice may be revoked by Borrower (by notice to the Administrative Agent on or prior to the specified effective date) if such condition is not satisfied. Any termination or reduction of the Commitments shall be permanent. Each reduction of the Commitments shall be made ratably among the Lenders in accordance with their respective Commitments. Section 2.10 Optional Prepayments. Borrower may, upon notice to each Lender identical to that required for related borrowings under this Agreement, from time to time and without premium or penalty, prepay its Notes, in whole or in part, so long as the aggregate amounts of all 25 30 partial prepayments of principal concurrently paid on such Notes equals $5,000,000 or any higher integral multiple of $1,000,000 or the aggregate outstanding balance of the Loans, and so long as Borrower does not prepay any Revolving Loan Advance, Competitive Bid Advance or Swing Line Advance except in accordance herewith. Any amounts prepaid pursuant to this Section shall be in addition to, and not in lieu of, all payments otherwise required to be paid under the Loan Documents at the time of such prepayment. Section 2.11 Payments to Lenders. Except as expressly set forth in Section 2.5(c) with respect to repayment of Swing Line Advances and Section 2.22(b) with respect to repayment of Competitive Bid Advances, Borrower will make each payment which it owes under the Loan Documents to Administrative Agent at its principal banking office in Dallas, Texas, or to such other office as Administrative Agent may specify from time to time by notice to Borrower for the account of each Lender to whom such payment is owed, without the application of any setoff, deduction or counterclaim. Each such payment must be received by Administrative Agent not later than 1:00 p.m., Dallas, Texas time, on the date such payment becomes due and payable, in lawful money of the United States of America and in immediately available funds. Any payment received by Administrative Agent after such time will be deemed to have been made on the next Business Day. Should any such payment become due and payable on a day other than a Business Day, the maturity of such payment shall be extended to the next succeeding Business Day (except, with respect to any Eurodollar Portion, as may be otherwise required by the definition of Eurodollar Interest Period), and, in the case of a payment of principal or past due interest, interest shall accrue and be payable thereon for the period of such extension as provided in the Loan Document under which such payment is due. All payments applied to principal or interest on any Note shall be applied first to any interest then due and payable, then to principal then due and payable, and last to any prepayment of principal and interest in compliance with Section 2.10. Unless otherwise expressly provided, all payments by any Designated Entity pursuant to this Agreement or any other Loan Document shall be made by such Designated Entity to Administrative Agent for account of Agents and Lenders pro rata among Obligations of the same type and, if applicable, having the same Eurodollar Interest Period or, in the case of Swing Line Advances or Competitive Bid Advances, the same maturity date. Section 2.12 Extension of Maturity Date and of Commitments. (a) Subject to the other provisions of this Agreement and provided that no Event of Default has occurred and is continuing, the total Commitments shall be effective for an initial period from the Effective Date to the Original Maturity Date; provided that the Maturity Date, and concomitantly the total Commitments, may be extended for successive 364 day periods expiring on the date which is 364 days from the then scheduled Maturity Date. If Borrower shall request in a Certificate of Extension delivered to the Administrative Agent not more than 60 days and not less than 45 days prior to the Maturity Date that the Maturity Date be extended for 364 days from the then scheduled Maturity Date, then the Administrative Agent shall promptly notify each Lender of such request and each Lender shall notify the Administrative Agent, no later than 30 days prior to the Maturity Date, whether such Lender, in the exercise of its sole discretion, will extend the 26 31 Maturity Date for such 364 day period. Any Lender which shall not timely notify the Administrative Agent whether it will extend the Maturity Date shall be deemed to not have agreed to extend the Maturity Date. No Lender shall have any obligation whatsoever to agree to extend the Maturity Date. Any agreement to extend the Maturity Date by any Lender shall be irrevocable, except as provided in clause (c) of this Section. (b) If all Lenders notify the Administrative Agent pursuant to clause (a) of this Section of their agreement to extend the Maturity Date, then the Administrative Agent shall so notify each Lender and Borrower, and such extension shall be effective without other or further action by any party hereto for such additional 364 day period. (c) If Lenders constituting at least the Majority Lenders approve the extension of the then scheduled Maturity Date (such Lenders agreeing to extend the Maturity Date herein called the "Accepting Lenders") and if one or more Lenders shall notify, or be deemed to notify, the Administrative Agent pursuant to clause (a) of this Section that they will not extend the then scheduled Maturity Date (such Lenders herein called the "Declining Lenders"), then (A) the Administrative Agent shall promptly so notify Borrower and the Accepting Lenders, (B) the Accepting Lenders shall, upon Borrower's election to extend the then scheduled Maturity Date in accordance with clause (i) or (ii) below, extend the then scheduled Maturity Date and (C) Borrower shall, pursuant to a notice delivered to the Administrative Agent, the Accepting Lenders and the Declining Lenders, no later than the tenth (10th) day following the date by which each Lender is required, pursuant to clause (a) of this Section, to approve or disapprove the requested extension of the total Commitments, either: (i) elect to extend the Maturity Date with respect to the Accepting Lenders and direct the Declining Lenders to terminate their Commitments, which termination shall become effective on the date which would have been the Maturity Date except for the operation of this Section. On such date, (x) Borrower shall deliver a notice of the effectiveness of such termination to the Declining Lenders with a copy to the Administrative Agent and (y) Borrower shall pay in full in immediately available funds all Obligations of Borrower owing to the Declining Lenders, including any amounts required pursuant to Section 2.19, and (z) upon the occurrence of the events set forth in clauses (x) and (y), the Declining Lenders shall each cease to be a Lender hereunder for all purposes, other than for purposes of Sections 2.16 through 2.20 and Section 6.4, and shall cease to have any obligations or any Commitment hereunder, other than to the Agents pursuant to Article 7, and the Administrative Agent shall promptly notify the Accepting Lenders and Borrower of the new Commitments; or (ii) elect to extend the Maturity Date with respect to the Accepting Lenders and, prior to or no later than the then scheduled Maturity Date, (A) to replace one or more of the Declining Lender or Declining Lenders with another lender or lenders reasonably acceptable to the Administrative Agent or any Accepting Lender (such lenders herein called the "Replacement Lenders") and (B) Borrower shall pay in full in immediately available funds all Obligations of Borrower owing to any Declining Lenders which are not being replaced, as provided in clause (i) above; provided that (x) the Replacement Lender or 27 32 Replacement Lenders shall purchase, and the Declining Lender or Declining Lenders shall sell, the Declining Lender's or Declining Lenders' rights and obligations hereunder without recourse or expense to, or warranty by, such Declining Lender or Declining Lenders being replaced for a purchase price equal to the aggregate outstanding principal amount of the Obligations payable to such Declining Lender or Declining Lenders plus any accrued but unpaid interest on such Obligations and accrued but unpaid fees or other amounts owing in respect of such Declining Lender's or Declining Lenders' Loans and Commitments hereunder, and (y) upon the payment of such amounts referred to in clause (x) and the execution of an Agreement to be Bound by the Replacement Lender or Replacement Lenders and the Declining Lender or Declining Lenders (which each such Declining Lender agrees to execute promptly), the Replacement Lender or Replacement Lenders shall each constitute a Lender hereunder and the Declining Lender or Declining Lenders being so replaced shall no longer constitute a Lender (other than for purposes of Sections 2.16 through 2.20 and Section 6.4), and shall no longer have any obligations hereunder, other than to the Agents pursuant to Article 7; or (iii) elect to revoke and cancel the extension request in such Certificate of Extension by giving notice of such revocation and cancellation to the Administrative Agent (which shall promptly notify the Lenders thereof) no later than the tenth (10th) day following the date by which each Lender is required, pursuant to clause (a) of this Section, to approve or disapprove the requested extension of the Maturity Date, and concomitantly the total Commitments. If Borrower fails to timely provide the election notice referred to in this clause (c), Borrower shall be deemed to have revoked and canceled the extension request in the Certificate of Extension and to have elected not to extend the Maturity Date, and, on the then scheduled Maturity Date, Borrower shall repay in full all Obligations under the Loan Documents. Section 2.13 [Intentionally Omitted]. Section 2.14 [Intentionally Omitted]. Section 2.15 [Intentionally Omitted]. Section 2.16 Capital Reimbursement. If either (a) the introduction or implementation of, or the compliance with, or any change in, or in the interpretation of, any law, rule or regulation, or (b) the introduction or implementation of or the compliance with any request, directive or guideline from any central bank or Governmental Authority (whether or not having the force of law) affects or would affect the amount of capital required to be maintained by any Lender or any corporation controlling any Lender, then, upon demand by such Lender, Borrower will immediately pay to Administrative Agent for the benefit of such Lender, from time to time as specified by such Lender, such additional amount which such Lender shall determine to be appropriate to compensate such Lender or any corporation controlling such Lender in light of such circumstances, to the extent that such Lender reasonably determines that, because of the existence of such circumstances, the amount of any such capital would be increased or the rate of return on any such capital would 28 33 be reduced, in whole or in part, by or as a consequence of the existence of such Lender's Commitments, its Loans, and its other commitments under this Agreement to Borrower, subject to the provisions of Section 2.21. Section 2.17 Increased Cost of Eurodollar Portions. If any applicable domestic or foreign law, treaty, rule, directive or regulation (whether now in effect or hereinafter enacted or promulgated, including Regulation D) or any interpretation or administration thereof by any Governmental Authority charged with the interpretation or administration thereof (whether or not having the force of law): (a) shall change the basis of taxation of payments to any Lender of any principal, interest, or other amounts attributable to any Eurodollar Portion of its Loans or its participation in any Swing Line Advances or its Competitive Bid Advances or otherwise due under this Agreement in respect of any Eurodollar Portion of its Loans or its participation in any Swing Line Advances or Competitive Bid Advances (other than taxes imposed on the overall net income of such Lender or any lending office of such Lender by any jurisdiction in which such Lender or any such lending office is located); (b) shall change, impose, modify, apply or deem applicable any reserve, special deposit or similar requirements in respect of any Eurodollar Portion of any Lender (excluding those for which such Lender is fully compensated pursuant to adjustments made in the definition of Adjusted Eurodollar Rate) or against assets of, deposits with or for the account of, or credit extended by, such Lender; or (c) shall impose on any Lender, the certificate of deposit market or the interbank eurocurrency deposit market any other condition affecting any Eurodollar Portion; and the result of any of the foregoing (a) through (c) is to (1) increase the cost to any Lender of funding or maintaining any Eurodollar Portion, any participation in any Swing Line Advance or any Competitive Bid Advance, as the case may be, or (2) to reduce the amount of any sum receivable by any Lender in respect of any Eurodollar Portion, Swing Line Advance or Competitive Bid Advance, as the case may be, by an amount reasonably deemed by such Lender to be material; then (i) such Lender shall promptly notify Administrative Agent and Borrower in writing of the happening of such event, (ii) Borrower shall thereafter upon demand pay to Administrative Agent for the account of such Lender such additional amount or amounts as will compensate such Lender for such additional cost or reduction, subject to the provisions of Sections 2.21 and 2.19, and (iii) Borrower may elect, by giving to Administrative Agent and Lender not less than three (3) Business Days' notice, to convert all (but not less than all) of any such Eurodollar Portion into a part of the Base Rate Portion. Section 2.18 Availability. If (a) any change in applicable laws, treaties, rules or regulations or in the interpretation or administration thereof in any jurisdiction whatsoever, domestic or foreign, shall make it unlawful or impracticable for any Lender to fund or maintain Eurodollar Portions, or shall materially restrict the authority of any Lender to purchase or take 29 34 offshore deposits of dollars ("Eurodollars"), or (b) any Lender determines that matching deposits appropriate to fund or maintain any Eurodollar Portion are not available to it, or (c) any Lender determines that the formula for calculating the Adjusted Eurodollar Rate does not fairly reflect the cost to such Lender of making or maintaining loans based on such rates, then, upon notice by such Lender to Administrative Agent and to Borrower, Borrower's right to elect Eurodollar Portions shall be suspended to the extent and for the duration of such illegality, impracticability, restriction or condition, and all Eurodollar Portions (or portions thereof) which are then outstanding or are then the subject of any Rate Election and which cannot lawfully or practicably be maintained or funded shall immediately become or remain part of the Base Rate Portions of such Lender's Loan, subject to the provisions of Sections 2.21 and 2.19. Borrower agrees to indemnify Administrative Agent and each Lender and hold Administrative Agent and each Lender harmless against all costs, expenses, claims, penalties, liabilities and damages which may result from any such change in law, treaty, rule, regulation, interpretation or administration, subject to the provisions of Section 2.21. Section 2.19 Funding Losses. In addition to its other obligations hereunder, subject to the provisions of Section 2.21, Borrower shall indemnify each Lender against, and reimburse each Lender on demand for, any loss or expense incurred or sustained by such Lender, determined as provided in this Section, as a result of (a) any payment or prepayment (whether authorized or required hereunder or otherwise) of all or a portion of a Eurodollar Portion of Borrower on a day other than the day on which the applicable Eurodollar Interest Period ends, (b) any payment or prepayment, whether required hereunder or otherwise, of a Loan of Borrower made after the delivery, but before the effective date, of a Rate Election, if such payment or prepayment prevents such Rate Election from becoming fully effective, (c) the failure of any Revolving Loan Advance or Swing Line Advance or Competitive Bid Advance to be made to Borrower or of any Rate Election of Borrower to become effective due to any condition precedent to a Revolving Loan Advance or Swing Line Advance or Competitive Bid Advance not being satisfied, due to the inability of Administrative Agent (acting reasonably and in accordance with Section 2.18) to determine a Eurodollar Rate for a Eurodollar Portion of Borrower or due to any other action or inaction of any Designated Entity, (d) any conversion (whether authorized or required hereunder or otherwise) of all or any portion of any Eurodollar Portion of Borrower into a Base Rate Portion or into a different Eurodollar Portion on a day other than the day on which the applicable Eurodollar Interest Period ends, (e) any payment or prepayment of all or a portion of a Swing Line Advance to Borrower on a day other than the maturity date for such Swing Line Advance or (f) any payment or prepayment of all or a portion of a Competitive Bid Advance on a day other than the maturity date for such Competitive Bid Advance. Upon the occurrence of an event as described in subsections (a) through (f) of this Section, the method to be used by each Lender to calculate the loss or expense incurred by reason of the liquidation or reemployment of deposits or other funds required by such Lender to fund or maintain Eurodollar Portions of Revolving Loan Advances, Swing Line Advances or Competitive Bid Advances, as the case may be, is as follows: 30 35 Funding Loss = P x (F-R) x D/360 P = principal amount of payment, prepayment, conversion, non-borrowing or non-effective Rate Election F = Eurodollar Rate or Swing Line Rate or Competitive Bid Rate, as the case may be (adjusted for Reserve Percentage), utilized in the calculations of the Eurodollar Rate or Swing Line Rate or Competitive Bid Rate, as the case may be, on the Eurodollar Portion or Swing Line Advance or Competitive Bid Advance which is being paid, prepaid, converted, not borrowed or not subject to effective Rate Election R = reinvestment rate (as hereinafter defined) D = number of days from the date of the payment, prepayment, conversion, non-borrowing or non-effectiveness until the day on which the Eurodollar Interest Period of the Eurodollar Portion ends or the Swing Line Advance or Competitive Bid Advance matures Reinvestment rate as it is used herein will be equal to the Eurodollar Rate, adjusted for the Reserve Percentage quoted to such Lender, or the Swing Line Rate or Competitive Bid Rate that would be quoted by such Lender, as the case may be, effective for the date on which the payment, prepayment, conversion, non-borrowing or non-effectiveness occurs. For purposes of determining the reinvestment rate for purposes of this Section, the Eurodollar Rate will be the quote for either one (1) month, two (2) months, three (3) months, six (6) months, nine (9) months or twelve (12) months, the Competitive Bid Rate will be the quote for a number of days between seven (7) and 360, and the Swing Line Rate will be the quote for a number of days between one (1) and fourteen (14), whichever most closely approximates (but which may contain more or fewer days than) the number of days from the date of the payment, prepayment, conversion, non-borrowing or non-effectiveness until the last day of the relevant Eurodollar Interest Period or the scheduled maturity, as the case may be, of the Eurodollar Portion, Competitive Bid Advance or Swing Line Advance, as the case may be, in respect of which the payment, prepayment, conversion, non-borrowing or non-effectiveness occurs; provided that if such number of days in respect of a Eurodollar Rate is the midpoint between two such periods, such rate will be the lower of the two rates for such periods. Section 2.20 Taxes. All payments by Borrower of principal of, and interest on, the Loans and all other amounts payable hereunder shall be made free and clear of and without deduction for any present or future income, excise, stamp, or franchise taxes and other taxes, fees, duties, withholdings or other charges of any nature whatsoever imposed by any taxing authority, but excluding franchise taxes and taxes imposed on or measured by any Lender's net income or receipts (such non-excluded items being called "Taxes"). In the event that any withholding or deduction from any payment to be made by Borrower hereunder is required in respect of any Taxes pursuant to any applicable law, rule or regulation, then, subject to the provisions of Section 2.21, Borrower will: 31 36 (a) pay directly to the relevant authority the full amount required to be so withheld or deducted; (b) promptly forward to Administrative Agent an official receipt or other documentation satisfactory to Administrative Agent evidencing such payment to such authority; and (c) pay to Administrative Agent for the account of the applicable Lender(s) such additional amount(s) as is necessary to ensure that the net amount actually received by each Lender will equal the full amount such Lender would have received had no such withholding or deduction been required and Borrower hereby acknowledges that it is not entitled to and will not seek recovery or restitution of any amount due to any of the Lenders or Agents and paid by Borrower pursuant to this clause (c) or pursuant to the next sentence. If any Taxes are directly asserted against any Agent or any Lender with respect to any payment received by such Agent or such Lender hereunder, such Agent or such Lender may pay such Taxes and, if paid in good faith, Borrower will promptly pay such additional amounts to Administrative Agent for the account of such Lender or Agent (including any penalties, interest or expenses) as is necessary in order that the net amount received by such person after the payment of such Taxes (including any taxes on such additional amount) shall equal the amount such person would have received had no such Taxes been asserted, subject to the provisions of Section 2.21. Borrower shall pay all stamp, transaction, registration and similar taxes (including financial institutions' duties, debit taxes or other taxes payable by return and taxes passed on to any Lender or Agent by a bank or financial institution (collectively "Stamp Taxes") and, if Borrower fails to pay any such charges or taxes after reasonable notice from any such Lender or Agent, fines and penalties) which may be payable or determined to be payable in relation to the execution, delivery, performance or enforcement of this Agreement or any Loan Document or any other transaction contemplated by any Loan Document to which Borrower is a party. Borrower hereby indemnifies each Lender and Agent against any liability resulting from delay or omission to pay such charges or taxes except to the extent the liability results from failure by the relevant Lender or Agent to pay any such tax after having been delivered funds to do so by Borrower or to the extent such liability is for fines and penalties resulting from such Lender's or Agent's failure to provide reasonable notice to Borrower as provided herein. If Borrower fails to pay any Taxes or Stamp Taxes when due to the appropriate taxing authority or fails to remit to Administrative Agent, for the account of the respective Lenders, the required receipts or other required documentary evidence, Borrower shall indemnify Lenders for any Taxes, interest or penalties that may become payable by any Lender as a result of any such failure, subject to the provisions of Section 2.21. For purposes of this Section, a distribution hereunder by Administrative Agent or any Lender to or for the account of any Lender or Agent shall be deemed a payment by the subject Borrower. Borrower waives any statutory right to recover from any Agent or any Lender any amount due to any such Agent or Lender and paid by Borrower under this Section. 32 37 On or prior to the first date on which interest or fees are payable hereunder for the account of any Lender, each Lender that is organized under the laws of a jurisdiction other than the United States shall execute and deliver to Administrative Agent, three (3) or more (as Administrative Agent may reasonably request) United States Internal Revenue Service Forms 1001 or 4224 or such other forms or documents (or successor forms or documents), appropriately completed, as may be applicable to establish the extent, if any, to which a payment to such Lender is exempt from withholding or deduction of Taxes. Each Lender which so delivers a Form 1001 or 4224 further undertakes to deliver to Administrative Agent three (3) additional copies of such form (or a successor form) on or before the date that such form expires or becomes obsolete or after the occurrence of any event requiring a change in the most recent form so delivered by it, and such amendments thereto or extensions or renewals thereof as may be reasonably requested by Administrative Agent, in each case certifying that such Lender is entitled to receive payments from Borrower under this Agreement and the Notes without deduction or withholding of any United States federal income taxes, unless an event (including without limitation any change in treaty, law or regulation) has occurred prior to the date on which any such delivery would otherwise be required which renders all such forms of the type previously delivered inapplicable or which would prevent such Lender from duly completing and delivering such form with respect to it and such Lender advises Administrative Agent that it is not capable of receiving such payments on the basis reflected in such previously delivered form without any deduction or withholding of United States federal income tax. Administrative Agent shall provide one (1) copy of each of such forms or documents so provided to Borrower and Documentation Agent. Section 2.21 Make-Whole Qualifications. Each Lender's claims for reimbursements, payments, indemnities or otherwise under Sections 2.16, 2.17, 2.18, 2.19 and 2.20 and Borrower's obligation with respect thereto, shall be limited and qualified by and subject to the following: (a) Borrower's obligation to pay, satisfy or recognize such claim shall be limited to costs or losses incurred within one (1) year immediately prior to any demand or request therefor upon Borrower; (b) each Lender's demand for reimbursement, payment or indemnity from Borrower must be limited to that which is being generally applied at the time by such Lender for comparable borrowers and credits subject to credit agreements similar to this Agreement, but without regard to provisions similar to this Section; (c) each Lender which asserts its rights with respect thereto or which is seeking or imposing such reimbursement, payment or indemnity shall provide evidence regarding the basis of such claim and the calculation and application thereof in reasonable detail and, in determining such amount, each Lender may use reasonable methods of attribution and averaging; (d) each Lender which is seeking payment or reimbursement pursuant to Section 2.20 shall, if so requested by Borrower, use reasonable efforts (subject to the overall policy considerations of such Lender) to designate a different lending office hereunder if to do so will avoid the need for, or reduce the amount of, any such 33 38 payment or reimbursement; provided that, Lender would, in its sole but reasonable determination, suffer no material economic, legal or regulatory disadvantage or burden; (e) Borrower may, in its sole discretion, elect, unless and until the applicable Lender notifies Borrower that the circumstances giving rise thereto no longer apply to such Lender, that, to the extent that a Lender's claims for such reimbursements, payments or indemnities would be reduced thereby, that subject to Section 2.19, (1) all Loans to Borrower which would otherwise be made by such Lender as Eurodollar Portions shall be made instead as Base Rate Portions (all of which interest and principal shall be payable as provided herein with respect to the related Eurodollar Portions of the Lenders), and (2) after each Eurodollar Portion has been repaid, all payments of principal which would otherwise would be applied to repay such Eurodollar Portion shall be applied to repay Base Rate Portions instead; and (f) Borrower may designate a replacement Lender (which may be one (1) or more of the then existing Lenders hereunder and which shall be reasonably satisfactory to Administrative Agent) to purchase the Notes, in each case without recourse, and assume the Commitments and all other obligations hereunder of any Lender that has suspended the availability of Eurodollar Portions pursuant to Section 2.18 or that has demanded reimbursement, payment or indemnity under Sections 2.16, 2.17, 2.18, 2.19 or 2.20, and such Lender shall be obligated to sell, transfer and deliver all of its Notes to such replacement Lender for the outstanding principal amount of such Notes, plus in each case, accrued interest thereon and such Lender's portion of accrued but unpaid fees through the date of such purchase, and permit such replacement lender to assume its Commitments. Borrower shall be obligated to pay all additional amounts due to the Lender being replaced pursuant to Sections 2.16, 2.17, 2.18, 2.19 and 2.20 through the date of such purchase and assumption; provided, that if the replacement Lender fails to purchase all such rights and interests and assume all such Commitments on the specified date in accordance herewith, Borrower shall continue to be obligated to pay such amounts to such Lender which was to have been replaced and provided further that Borrower shall pay any Taxes or Stamp Taxes, if any, as a result of such transfer. Section 2.22 Competitive Bid Advances. (a) In addition to borrowings pursuant to Section 2.1(a) or Section 2.4, Borrower may request each Lender severally to submit offers (herein called a "Competitive Bid Offer") to make advances to Borrower on any Business Day during the Loan Commitment Period as provided in this Section (herein called "Competitive Bid Advances"); provided, however, that each Lender may in its sole discretion, but shall have no obligation whatsoever to submit such offers, and Borrower may, but shall have no obligation to, accept any such offers. 34 39 (b) Procedure for Competitive Bid Advances. (i) Borrower may request Competitive Bid Advances by delivering a request for a Competitive Bid Advance to each Lender (which has indicated to Borrower its interest in making a Competitive Bid Advance) and Administrative Agent not later than 9:00 a.m., Dallas, Texas time, one (1) Business Day prior to the proposed borrowing date. Each request for a Competitive Bid Advance shall be in substantially the form of Exhibit N hereto (herein called a "Request for Competitive Bid Offer") and may solicit bids for Competitive Bid Advances having not more than three (3) alternative maturity dates and for Competitive Bid Advances in any respective principal amount equal to $10,000,000 or an integral multiple of $1,000,000 in excess thereof for each maturity date requested. The maturity date for each Competitive Bid Advance shall be not less than fifteen (15) days nor more than 360 days after the borrowing date therefor (and in any event not after the Maturity Date). (ii) Upon receipt of a Request for Competitive Bid Offer, any Lender that elects, in its sole discretion, to do so, shall irrevocably offer to make one (1) or more Competitive Bid Advances at a fixed rate of interest determined by such Lender in its sole discretion for each such Competitive Bid Advance. Any such irrevocable offer shall be made by delivering a Competitive Bid Offer to Administrative Agent and to Borrower, before 9:00 a.m., Dallas, Texas time (or, in the case of a Competitive Bid Offer by Administrative Agent, before 8:45 a.m., Dallas, Texas time), on the proposed borrowing date, setting forth the maximum amount of Competitive Bid Advances for each maturity date, and the aggregate maximum amount for all maturity dates, which such Lender would be willing to make (which amounts may exceed such Lender's Percentage Share of the Commitments) and the fixed rate of interest at which such Lender is willing to make each such Competitive Bid Advance, which fixed rate of interest may or may not be, in such Lender's discretion, different for each Competitive Bid Advance (respectively herein a "Competitive Bid Rate"). Borrower shall pay to Administrative Agent a fee of $500 on each day that Borrower accepts a Competitive Bid Offer. (iii) The Competitive Bid Offer delivered by each Lender in response to a Request for Competitive Bid Offer shall set forth an amount proposed to be loaned by such Lender for each maturity date requested by Borrower that is equal to $10,000,000 or an integral multiple of $1,000,000 in excess thereof. Any Competitive Bid Offer by any Lender that: (A) does not substantially conform to the form of Exhibit O hereto, (B) contains qualifying, conditional or similar language, (C) proposes terms other than or in addition to those set forth in the applicable Request for Competitive Bid Offer or (D) is received by Borrower after the applicable time specified in 35 40 this subsection, shall be rejected by Borrower and Administrative Agent (and Administrative Agent shall notify the relevant Lender of such rejection for one or more of the matters described in the foregoing (A) through (D) by telephone and telecopy as soon as practicable thereafter). (iv) Borrower shall before 10:00 a.m., Dallas, Texas time, on the proposed borrowing date either, in its absolute discretion: (A) withdraw such Request for Competitive Bid Offer by giving telephonic notice to that effect; (B) accept one (1) or more of the Competitive Bid Offers by giving telephonic notice to Administrative Agent (immediately confirmed by delivery to Administrative Agent by facsimile transmission of a Bid Acceptance) of the amount of Competitive Bid Advance(s) for each relevant maturity date to be made by the relevant Lender(s) (which amount for each such maturity date shall be equal to or less than the maximum amount for such maturity date specified in the Competitive Bid Offer of such Lender(s), and for all maturity dates included in such Competitive Bid Offer shall be equal to or less than the aggregate maximum amount specified in such Request for Competitive Bid Offer for all such maturity dates) and reject any Competitive Bid Offers not accepted by Borrower by giving telephonic notice to Administrative Agent of such rejection; provided, however, that (1) Borrower may not accept Competitive Bid Offers for any maturity date in an aggregate principal amount in excess of the maximum principal amount requested in the related Request for Competitive Bid Offer (and Competitive Bid Advances allocated to a Lender on a borrowing date for each relevant maturity date shall be in a principal amount equal to $10,000,000 or an integral multiple of $1,000,000 in excess thereof); and (2) Administrative Agent shall notify the Lender that submitted a Competitive Bid Offer for such Business Day of Borrower's decision by telecopying to each such Lender a copy of the Bid Acceptance by no later than 12:00 noon, Dallas, Texas time, on the borrowing date specified in the Request for Competitive Bid Offer; or (C) Borrower may accept or reject any Competitive Bid Offer(s) in whole or in part; provided that after giving effect to any such accepted Competitive Bid Offer(s), the sum of (i) the aggregate principal amount of the Revolving Loans and Swing Line Advances outstanding at such time, and (ii) the aggregate principal amount of Competitive Bid Advances outstanding at such time, does not exceed the Facility Amount. 36 41 (v) If Borrower notifies Administrative Agent that a Request for Competitive Bid Offer is withdrawn pursuant to clause (iv) above, the Competitive Bid Advance requested thereby shall not be made. (vi) Each Lender which is to make a Competitive Bid Advance shall, before 1:00 p.m., Dallas, Texas time, on the borrowing date specified in the Request for Competitive Bid Offer applicable thereto, make available to Administrative Agent in immediately available funds the amount of each Competitive Bid Advance to be made by such Lender. Administrative Agent shall deposit such funds to an account designated by Borrower by no later than 1:15 p.m., Dallas, Texas time, on such date. (vii) Borrower shall repay to Administrative Agent, for the account of each Lender which has made a Competitive Bid Advance, on the maturity date of each Competitive Bid Advance (such maturity date being that specified by Borrower for repayment of such Competitive Bid Advance in the related Request for Competitive Bid Offer) the then unpaid principal amount of such Competitive Bid Advance. Borrower shall not have the right to prepay any principal amount of any Competitive Bid Advance. If any Lender makes a Competitive Bid Advance on a day on which Borrower is to repay all or any part of an outstanding Competitive Bid Advance from such Lender, if requested by Borrower, such Lender shall apply the proceeds of its new Competitive Bid Advance to make such repayment and, in such instance, only an amount equal to the difference (if any) between the amount being borrowed and the amount being repaid shall be made available by such Lender to Administrative Agent as provided in Section 2.22(b)(vi), or remitted by Borrower to Administrative Agent as provided in this Section 2.22(b)(vii), as the case may be. (viii) Borrower shall pay interest on the unpaid principal amount of each Competitive Bid Advance from the borrowing date to the stated maturity date thereof, at the rate of interest determined pursuant to clause (b) (ii) above (calculated on the basis of a 360 day year for actual days elapsed including the first but excluding the last), but not in excess of the Maximum Lawful Rate, payable on the maturity date with respect to such Competitive Bid Advance and, if such maturity date is more than 90 days after the date of making such Competitive Bid Advance, on such ninetieth day and each ninetieth day occurring after such ninetieth day until the maturity date. If all or a portion of the principal of or interest on any Competitive Bid Advance shall not be paid when due (whether at the stated maturity, by acceleration or otherwise), without limiting any rights of any Lender under this Agreement, (i) such overdue principal amount shall bear interest from the date on which such payment was due (other than on the scheduled maturity date with respect thereto) at the Default Rate, but not in excess of the Maximum Lawful Rate, until paid in full (as well as after as before 37 42 judgment) and (ii) such overdue interest shall bear interest from the date on which payment was due at the Default Rate, but not in excess of the Maximum Lawful Rate, until paid in full (as well as after as before judgment). (c) The Competitive Bid Advances made by each Lender shall be evidenced by a single promissory note of Borrower payable to the order of such Lender substantially in the form of Exhibit A-3 attached hereto, with appropriate insertions (herein called a "Competitive Bid Note"). The date, amount, Competitive Bid Rate and maturity date of each Competitive Bid Advance made by a Lender to Borrower, and each payment made on account of the principal thereof, shall be recorded by such Lender on its books. (d) The Competitive Bid Advances will be used by Borrower to provide working capital and for the general business purposes of Borrower and its Subsidiaries. No Competitive Bid Advances shall be used for the purpose of purchasing or carrying any Margin Stock in violation of the Margin Regulations. (e) The obligation of Lenders to make each Competitive Bid Advance after timely acceptance by Borrower is further subject to the conditions contained in Article 3. (f) Borrower shall not be required to accept Competitive Bid Offers on the basis of the lowest Competitive Bid Rate offered, but may in its sole discretion accept any Competitive Bid Offer regardless of the Competitive Bid Rate(s) offered.

If any Default shall occur and be continuing, each Lender or Administrative Agent on behalf of Lenders may protect and enforce its rights under the Loan 59 64 Documents by any appropriate proceedings, including, without limitation, proceedings for specific performance of any covenant or agreement contained in any Loan Document, and each Lender may enforce the payment of any Obligations due it or enforce any other legal or equitable rights which it may have. Additionally, under such circumstances, the Required Lenders or, at the direction of Required Lenders, the Trustee (or Collateral Agent) may proceed to protect the Lenders' rights under the Security Instruments. All rights, remedies and powers conferred upon Administrative Agent and Lenders under the Loan Documents are cumulative and not exclusive of any other rights, remedies or powers available under the Loan Documents or at law or in equity. Section 6.3 Annulment of Acceleration. If a declaration of acceleration is made pursuant to this Article 6, then Required Lenders, by written notice to Borrower and Administrative Agent, may collectively rescind and annul such declaration in its entirety; provided, that at the time such declaration is annulled and rescinded: (a) no judgment or decree has been entered for the payment of any moneys due pursuant to any Note or this Agreement; (b) all arrears of interest upon all the Notes and all other sums payable under the Notes and this Agreement (other than principal amounts which may have become due as a result of acceleration), including interest upon overdue interest, to the extent payment thereof is lawful, shall have been duly paid; and (c) each and every other Event of Default which has theretofore occurred shall have been waived pursuant to Section 8.1 or otherwise made good or cured. Section 6.4 Indemnity. Borrower hereby indemnifies each Agent and each Lender, from and against any and all liabilities, obligations, claims, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements (including reasonable fees of attorneys, accountants, experts and advisors) of any kind or nature whatsoever (in this Section collectively called "liabilities and costs") which to any extent (in whole or in part) may be imposed on, incurred by, or asserted against such Agent or such Lender as a result of, arising out of, relating to or in connection with: (a) the Loan Documents to which Borrower or one or more of its Subsidiaries is a party or the rights provided therein (including the enforcement or defense thereof); (b) the direct or indirect application or proposed application of the proceeds of any Loan to or for Borrower or any of its Subsidiaries; (c) any transaction financed or to be financed in whole or in part, directly or indirectly, with the proceeds of any Loan to or for Borrower or any of its Subsidiaries; (d) any investigation, litigation or proceeding related to any environmental cleanup, audit, compliance or other matter (including enforcement) relating to any 60 65 Environmental Law or the condition of any facility or property owned, leased or operated by Borrower or any of its Subsidiaries; or (e) the presence on or under, or the escape, seepage, leakage, spillage, discharge, emission, discharging or releases from, any facility owned or operated by Borrower or any of its Subsidiaries of any hazardous or toxic substance (including any liabilities and costs under any Environmental Law), regardless of whether caused by, or within the control of, Borrower or any of its Subsidiaries; or any misrepresentation, inaccuracy or any breach in or of Section 4.1(j) or Section 5.1(i) by or with respect to Borrower or any of its Subsidiaries. The foregoing indemnification shall not apply to the extent such liabilities and costs are determined to have resulted or been caused, in whole or in part, by the gross negligence or willful misconduct on the part of such Agent or Lender. THE FOREGOING INDEMNIFICATION SHALL APPLY WHETHER OR NOT SUCH LIABILITIES AND COSTS ARE IN ANY WAY OR TO ANY EXTENT CAUSED, IN WHOLE OR IN PART, BY ANY NEGLIGENT ACT OR OMISSION OF ANY KIND EXCEPT AS PROVIDED BY THE IMMEDIATELY PRECEDING SENTENCE. In the event that any claim or demand for which Borrower would be liable to any Agent or any Lender under this Section is asserted against or sought to be collected from any Agent or any Lender by a third party, Agent or such Lender shall promptly notify Borrower of such claim or demand. Borrower shall have the lesser of: (i) thirty (30) Business Days from receipt of the above notice; or (ii) three (3) Business Days prior to the expiration of any period after which a default judgment may be entered against such Agent or Lender (the "Notice Period") to notify such Agent and/or Lender whether or not Borrower desires, at the sole cost and expense of Borrower, to defend such Agent and/or Lender against such claim or demand. In the event that Borrower notifies such Agent and/or Lender within the Notice Period, that it desires to defend such Agent and/or Lender against such claim or demand, Borrower shall have the right to settle or otherwise dispose of such claim or demand (other than claims alleging criminal violations) on such terms as Borrower, with the consent of the indemnified party (which consent shall not be unreasonably withheld) shall deem appropriate; provided that: (w) counsel designated by Borrower is reasonably acceptable to the Managing Agents and the affected Lender; (x) Borrower will have acknowledged in writing that this Section will cover any liabilities and costs in any such claim or demand; (y) in the sole determination of the Managing Agents and the affected Lender, Borrower will have the financial ability to pay such liabilities and costs; and 61 66 (z) Borrower shall thereafter consult with the Managing Agents and the affected Lender with respect to such claim or demand; and provided further, that each of Agents and the affected Lender shall have the right at all times to participate in any proceeding, at their sole cost and expense, subject, however, to Borrower's right to control the defense of all proceedings concerning such claim or demand. In the event that Borrower fails to give such Agent and/or Lender such notice, such Agent and/or Lender may defend against such claim or demand; provided, however, that Borrower's obligation to reimburse such Agent and/or Lender shall be limited to a single law firm of such Agent and/or Lender (unless Borrower otherwise consents, which consent shall not be unreasonably withheld); provided further, that Borrower shall have the right at all times to participate in any such proceeding, at its sole cost and expense, subject, however, to the right of such Agent and/or Lender to control the defense of all proceedings concerning such claim or demand. As used in this Section, the terms "Agent" and "Lender" shall refer not only to the Persons designated as such in Section 1.1 but also to each director, officer, agent, attorney, employee and representative of such Person. ARTICLE 7 AGENTS Section 7.1 Appointment and Authority. NationsBank of Texas, N.A. is hereby appointed Administrative Agent hereunder and under each other Loan Document, CIBC Inc. is hereby appointed Documentation Agent hereunder and under each other Loan Document, Morgan Guaranty Trust Company of New York is hereby appointed Documentation Agent hereunder and under each other Loan Document and The Chase Manhattan Bank is hereby appointed Syndication Agent hereunder and under each other Loan Document, each Co-Agent is hereby appointed Co-Agent hereunder and under each other Loan Document, and each of the Lenders hereby authorizes each such Agent to act as the agent of such Lender hereunder and each other Loan Document to the extent provided herein or therein. In addition, each Lender hereby irrevocably authorizes Administrative Agent, and Administrative Agent hereby undertakes, to receive payments of principal, interest due hereunder as specified herein and to act as Collateral Agent under the Security Instruments. In addition, each Lender hereby authorizes each Agent, and each Agent hereby undertakes to take all other actions and to exercise such powers under the Loan Documents as are specifically delegated to such Agent by the terms hereof or thereof, together with all other powers reasonably incidental thereto. No Co-Agent has any duties or responsibilities whatsoever as Co-Agent (as opposed to its capacity as Lender) under or in connection with this Agreement or any of the Loan Documents. The relationship of each Agent to Lender is only that of one commercial bank acting as administrative agent for others, and nothing in the Loan Documents shall be construed to 62 67 constitute any Agent a trustee or other fiduciary for any holder of any of the Notes or of any participation therein, nor to impose on any Agent duties and obligations other than those expressly provided for in the Loan Documents. None of the Agents shall have implied duties to Lenders, or any obligations to Lenders to take any action under the Loan Documents, except any action by an Agent specifically provided by the Loan Documents to be taken by such Agent. With respect to any matters not expressly provided for in the Loan Documents and any matters which the Loan Documents place within the discretion of any Agent, such Agent shall not be required to exercise any discretion or take any action, and each such Agent may request instructions from Lenders with respect to any such matter, in which case such Agent shall be required to act or to refrain from acting (and shall be fully protected and free from liability to any and all Lenders and Agents in so acting or refraining from acting) upon the instructions of Required Lenders (including itself); provided, however, that no Agent shall be required to take any action which exposes it to a risk of personal liability that it considers unreasonable or which is contrary to the Loan Documents or to applicable law unless indemnified to its satisfaction by Lenders or Borrower. Upon receipt by Administrative Agent from Borrower of any communication calling for action on the part of Lenders or upon notice from any Lender to Administrative Agent of any Default or Event of Default, Administrative Agent shall promptly notify each Lender thereof. Section 7.2 Agent's Reliance. No Agent or any of their respective directors, officers, agents, attorneys, or employees shall be liable for any action taken or omitted to be taken by any of them under or in connection with the Loan Documents, including their negligence of any kind, except that each shall be liable for its own gross negligence or willful misconduct. Without limiting the generality of the foregoing, each Agent: (a) may treat the payee of any Note as the holder thereof until Administrative Agent receives written notice of the assignment or transfer thereof in accordance with this Agreement, signed by such payee and in form satisfactory to Administrative Agent; (b) may consult with legal counsel (including counsel for Borrower), independent public accountants and other experts selected by such Agent and shall not be liable for any action taken or omitted to be taken in good faith by it in accordance with the advice of such counsel, accountants or experts; (c) makes no warranty or representation to any Lender or to any other Agent and shall not be responsible to any Lender or Agent for any statements, warranties or representations made in or in connection with the Loan Documents by any other Person; (d) shall not have any duty to ascertain or to inquire as to the performance or observance of any of the terms, covenants or conditions of the Loan Documents 63 68 on the part of any Designated Entity or to inspect the property (including the books and records) of any Designated Entity; (e) shall not be responsible to any Lender or to any other Agent for the due execution (other than its own due execution and delivery), legality, validity, enforceability, genuineness, existence, sufficiency or value of any Loan Document, the Credit Facility Agreement or any instrument or document furnished in connection herewith, or any collateral; (f) may rely upon the representations and warranties of any Designated Entity and the Lenders in exercising its powers hereunder; (g) shall not be responsible for the satisfaction of any condition specified in Article 3, except receipt by an Agent of items required to be delivered to such Agent; and (h) shall incur no liability under or in respect of the Loan Documents by acting upon any notice, consent, certificate or other instrument or writing (including any telecopy, telegram, cable or telex) believed by it to be genuine and signed or sent by the proper Person or Persons. Section 7.3 Lenders' Credit Decisions. Each Lender acknowledges that it has, independently and without reliance upon any Agent or any other Lender, made its own analysis of Designated Entities and the transactions contemplated hereby and its own independent decision to enter into this Agreement and the other Loan Documents. Each Lender also acknowledges that it will, independently and without reliance upon any Agent or any other Lender and based on such documents and information as it shall deem appropriate at the time, continue to make its own credit decisions in taking or not taking action under the Loan Documents. Section 7.4 Indemnification. Each Lender agrees to indemnify each Agent (to the extent not reimbursed by Borrower within ten (10) days after demand) from and against such Lender's Percentage Share of any and all liabilities, obligations, claims, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements (including reasonable fees of attorneys, accountants, experts, and advisors) of any kind or nature whatsoever (in this Section collectively called "liabilities and costs") which to any extent (in whole or in part) may be imposed on, incurred by, or asserted against such Agent growing out of, resulting from or in any other way associated with any of the Loan Documents and the transactions and events (including, without limitation, the enforcement thereof) at any time associated therewith or contemplated therein. THE FOREGOING INDEMNIFICATION SHALL APPLY WHETHER OR NOT SUCH LIABILITIES AND COSTS ARE IN ANY WAY OR TO ANY EXTENT CAUSED, IN WHOLE OR IN PART, BY ANY NEGLIGENT ACT OR 64 69 OMISSION OF ANY KIND BY ANY AGENT, PROVIDED ONLY THAT NO LENDER SHALL BE OBLIGATED UNDER THIS SECTION TO INDEMNIFY AN AGENT FOR THAT PORTION, IF ANY, OF ANY LIABILITIES AND COSTS WHICH IS THE SOLE RESULT OF SUCH AGENT'S OWN INDIVIDUAL GROSS NEGLIGENCE OR WILLFUL MISCONDUCT, AS DETERMINED IN A FINAL JUDGMENT OF A COURT OF COMPETENT JURISDICTION. Cumulative of the foregoing, each Lender agrees to reimburse Administrative Agent, each Documentation Agent and Syndication Agent promptly upon demand for such Lender's Percentage Share of any costs and expenses to be paid to Administrative Agent, the Documentation Agent or the Syndication Agent by Borrower under Section 5.1(h) to the extent that Administrative Agent, the Documentation Agent or the Syndication Agent is not timely reimbursed for such expenses by Borrower as provided in such section. As used in this Section the term "Agents" shall refer not only to the Person(s) designated as such in Section 1.1 but also to each director, officer, agent, attorney, employee and representative of such Person(s). Section 7.5 Rights as Lender. In their respective capacity as a Lender, each Agent shall have the same rights and obligations as any Lender and may exercise such rights as though it were not an Agent. Each Agent may accept deposits from, lend money to, act as trustee under indentures of, and generally engage in any kind of business with any of Designated Entities or their Affiliates, all as if it were not an Agent hereunder and without any duty to account therefor to any other Lender. Section 7.6 Sharing of Set-Offs and Other Payments. Each Agent and Lender agrees that if it shall, whether through the exercise of rights under security documents or rights of banker's lien, setoff, or counterclaim against any Designated Entity or otherwise, obtain payment of a portion of the aggregate Obligations owed to it (other than in respect of its Swing Line Advances and its Competitive Bid Advances) which, taking into account all distributions made by Administrative Agent under Section 2.11, causes such Agent or such Lender to have received more than it would have received had such payment been received by Administrative Agent and distributed pursuant to Section 2.11 (or, in the case of Swing Line Advances paid as provided in Section 2.5(c) or in the case of Competitive Bid Advances paid as provided in Section 2.22(b)), then it shall be deemed to have simultaneously purchased and shall be obligated to purchase interests in the Obligations as necessary to cause Administrative Agent and all Lenders to share all payments (other than in respect of Swing Line Advances and Competitive Bid Advances) as provided for in Section 2.11, and such other adjustments shall be made from time to time as shall be equitable to ensure that all Agents and all Lenders share all payments of Obligations (other than in respect of its Swing Line Advances and Competitive Bid Advances) as provided in Section 2.11. If any Agent or any Lender, whether in connection with setoff of amounts which might be subject to setoff or otherwise, receives collateral or other protection for its Obligations or such amounts which might be subject to setoff, such Agent or Lender agrees, promptly upon demand, to take such action necessary so that all Agents and all Lenders share in the benefits of such collateral ratably in proportion to 65 70 the Obligations owing to each of them. Nothing herein contained shall in any way affect the right of any Agent or any Lender to obtain payment (whether by exercise of rights of banker's lien, set-off or counterclaim or otherwise) of indebtedness other than the Obligations. Borrower expressly consents to the foregoing arrangements and agrees that any holder of any such interest or other participation in the Obligations, whether or not acquired pursuant to the foregoing arrangements, may to the fullest extent permitted by law exercise any and all rights of banker's lien, set-off, or counterclaim as fully as if such holder were a holder of the Obligations in the amount of such interest or other participation. If all or any part of any funds transferred pursuant to this Section is thereafter recovered from the seller under this Section which received the same, the purchase provided for in this Section shall be deemed to have been rescinded to the extent of such recovery, together with interest, if any, if interest is required pursuant to court order to be paid on account of the possession of such funds prior to such recovery. Section 7.7 Investments. Whenever Administrative Agent in good faith determines that it is uncertain about how to distribute to Lenders any funds which it has received, or whenever Administrative Agent in good faith determines that there is any dispute among Lenders about how such funds should be distributed, Administrative Agent may choose to defer distribution of the funds which are the subject of such uncertainty or dispute. If Administrative Agent in good faith believes that the uncertainty or dispute will not be promptly resolved, or if Administrative Agent is otherwise required to invest funds pending distribution to Lenders, Administrative Agent may invest such funds pending distribution (at the risk of the subject Borrower); all interest on any such investment shall be distributed upon the distribution of such investment and in the same proportion and to the same Persons as such investment. All moneys received by Administrative Agent for distribution to Lenders (other than to the Person who is Administrative Agent in its separate capacity as a Lender) shall be held by Administrative Agent pending such distribution solely as Administrative Agent for such Lenders, and Administrative Agent shall have no equitable title to any portion thereof. Section 7.8 Benefit of Article 7. The provisions of this Article (other than the following Section 7.9) are intended solely for the benefit of Agent and Lenders, and no Designated Entity shall be entitled to rely on any such provision or assert any such provision in a claim or defense against Agent or any Lender. Agent and Lenders may waive or amend such provisions as they desire without any notice to or consent of any Designated Entity. Section 7.9 Resignation and Removal. Any Agent may resign at any time by giving written notice thereof to Lenders and Borrower. Each such notice shall set forth the date of such resignation. Majority Lenders or Borrower, with the consent (which shall not be unreasonably withheld) of Majority Lenders (other than Agent to be removed) shall be entitled to remove any Agent. Upon any such resignation or removal, Borrower may, with the written concurrence (which shall not be unreasonably withheld) of Majority Lenders (exclusive of any such resigned or removed Agent), designate a successor Agent. If, within fifteen (15) days 66 71 after the date of such resignation or removal, Borrower makes no such designation or such written concurrence is not given, Majority Lenders (exclusive of any such resigned or removed Agent) shall, with the consent of Borrower (which consent shall not be unreasonably withheld or delayed), have the right to appoint a successor Agent. A successor must be appointed for any retiring Managing Agent, and such Managing Agent's resignation shall become effective when such successor accepts such appointment. Upon the acceptance of any appointment as a Managing Agent hereunder by a successor Managing Agent and the satisfaction of all obligations on the part of such retiring or removed Managing Agent necessary to facilitate succession, the retiring or removed Managing Agent, as the case may be, shall be discharged from its duties and obligations under this Agreement and the other Loan Documents. After any Agent's resignation or removal hereunder, the provisions of this Article 7 shall continue to inure to its benefit as to any actions taken or omitted to be taken by it while it was Agent under the Loan Documents. Any out-going Agent shall promptly execute all assignments and other documents necessary to effectuate the transfer of the agency in connection with this Agreement and shall promptly deliver all original documents and any collateral in its possession to the successor Agents. ARTICLE 8 MISCELLANEOUS Section 8.1 Waivers and Amendments. No failure or delay (whether by course of conduct or otherwise) by any Agent or any Lender in exercising any right, power or remedy which any Agent or Lender may have under any of the Loan Documents shall operate as a waiver thereof or of any other right, power or remedy, nor shall any single or partial exercise by any Agent or Lender of any such right, power or remedy preclude any other or further exercise thereof or of any other right, power or remedy. No waiver of any provision of any Loan Document and no consent to any departure therefrom shall ever be effective unless it is in writing and signed as provided below in this Section, and then such waiver or consent shall be effective only in the specific instances and for the purposes for which given and to the extent specified in such writing. No notice to or demand on any Designated Entity shall in any case of itself entitle any Designated Entity to any other or further notice or demand in similar or other circumstances. This Agreement and the other Loan Documents set forth the entire understanding between the parties hereto with respect to the transactions contemplated herein and therein and supersede all prior discussions and understandings with respect to the subject matter hereof and thereof, and no waiver, consent, release, modification or amendment of or supplement to this Agreement or the other Loan Documents shall be valid or effective against any party hereto unless the same is in writing and signed by (a) if such party is a Designated Entity, by such Designated Entity, (b) if such party is an Agent, by such Agent and (c) if such party is a Lender, by such Lender or by Administrative Agent on behalf of Lenders with the written consent of Required Lenders (or without further consent than that already provided herein in the circumstances provided in Section 8.7). Notwithstanding the foregoing or 67 72 anything to the contrary herein or in any other Loan Document, no Agent shall, without the prior consent of each Lender, execute and deliver on behalf of any Lender any waiver or amendment which would: (i) increase the Commitment of such Lender or subject such Lender to any additional obligations; (ii) reduce or forgive any fees hereunder, or the principal of, or interest on, such Lender's Notes; (iii) postpone any date fixed for any payment of any fees hereunder, or principal of, or interest on, such Lender's Notes; (iv) amend the definitions herein of "Required Lenders" or "Majority Lenders" or otherwise change the aggregate amount of Percentage Shares which is required for Administrative Agent, any other Agent, Lenders or any of them to take any particular action under the Loan Documents; (v) release collateral (except as expressly contemplated by this Agreement) or any Borrower from its obligation to pay such Lender's Notes or any Restricted Subsidiary from its Guaranty (except upon the Restricted Subsidiary becoming an Unrestricted Subsidiary as specified in this Agreement); (vi) amend this Section 8.1; (vii) extend the Loan Commitment Period; (ix) amend, modify or waive any provision applicable to the indemnification of any Lender; (x) consent to the assignment or transfer by any Designated Entity of any of its rights or obligations under this Agreement or the other Loan Documents; or (xi) amend, modify or waive the rights and obligations of the Agents; provided, that no obligation to any Designated Entity of any Lender or any Agent may be amended, modified or waived without the written approval of Borrower, which approval shall not be unreasonably withheld. Notwithstanding the foregoing or anything to the contrary herein or in any other Loan Document, no provision of Article 7 may be amended in any way which impacts or affects any Agent in its capacity as an Agent (as opposed to its capacity as a Lender) without the prior written consent of such Agent. Except as provided in the preceding three sentences or as 68 73 expressly provided in any Loan Document, the Required Lenders may waive, modify, amend or supplement this Agreement and each of the other Loan Documents. Section 8.2 Survival of Agreements; Cumulative Nature. Each Designated Entity's various representations, warranties, covenants, indemnities and agreements in the Loan Documents shall survive the execution and delivery of this Agreement and the other Loan Documents and the performance hereof and thereof, including the making or granting of the Loans and the delivery of the Notes, and the other Loan Documents, and shall further survive until all of the Obligations are paid in full to Agents and Lenders and all of Agents' and Lenders' obligations to Borrower are terminated, provided that, notwithstanding the foregoing, certain Obligations of certain Designated Entities under their respective Guaranties shall survive or be reinstated as provided in such Guaranties. The representations, warranties, indemnities, and covenants made by any Designated Entity in any Loan Documents, and the rights, powers, and privileges granted to Agents and Lenders in the Loan Documents, are cumulative. Section 8.3 Notices. All notices, requests, consents, demands and other communications required or permitted under any Loan Document shall be in writing, unless otherwise specifically provided in such Loan Document (provided that Administrative Agent may give telephonic notices to the other Agents and Lenders), and shall be deemed sufficiently given or furnished if delivered by personal delivery, by telecopy (with telephonic confirmation of transmission), by delivery service with proof of delivery, or by registered or certified United States mail, postage prepaid, to Borrower at the address of Borrower specified on the signature pages hereto and to each Agent and each Lender at their addresses specified on the signature pages hereto (unless changed by similar notice in writing given by the particular Person whose address is to be changed). Any such notice or communication shall be deemed to have been given: (a) in the case of personal delivery or delivery service, as of the date of first attempted delivery during normal business hours at the address provided herein; (b) in the case of telecopy, upon receipt; or (c) in the case of registered or certified United States mail, three (3) days after deposit in the mail, postage prepaid; provided, however, that no Request for Advance or Rate Election shall become effective until actually received by Administrative Agent. Section 8.4 Parties in Interest. All grants, covenants and agreements contained in the Loan Documents shall bind and inure to the benefit of the parties thereto and their respective successors and assigns; provided, however, that no Designated Entity may assign or 69 74 transfer any of its rights or delegate any of its duties or obligations under any Loan Document without the prior written consent of all Lenders. Section 8.5 Governing Law. THE LOAN DOCUMENTS SHALL BE DEEMED CONTRACTS AND INSTRUMENTS MADE UNDER THE LAWS OF THE STATE OF TEXAS AND SHALL BE CONSTRUED AND ENFORCED IN ACCORDANCE WITH AND GOVERNED BY THE LAWS OF THE STATE OF TEXAS AND THE LAWS OF THE UNITED STATES OF AMERICA, WITHOUT REGARD TO PRINCIPLES OF CONFLICTS OF LAW. CHAPTER 15 OF TEXAS REVISED CIVIL STATUTES ANNOTATED ARTICLE 5069 (WHICH REGULATES CERTAIN REVOLVING CREDIT LOAN ACCOUNTS AND REVOLVING TRI-PARTY ACCOUNTS) DOES NOT APPLY TO THIS AGREEMENT OR TO THE NOTES. Section 8.6 Limitation on Interest. It is the intention of the parties hereto to conform strictly to applicable usury laws and, anything herein or any other Loan Document to the contrary notwithstanding, the obligations of Designated Entities to a Lender or an Agent under this Agreement and the Loan Documents shall be subject to the limitation that payments of interest shall not be required to the extent that receipt thereof would be contrary to provisions of law applicable to such Lender or Agent limiting rates of interest which may be charged or collected by such Lender or Agent. Accordingly, if the transactions contemplated hereby would be usurious under laws applicable to a Lender or Agent (including the federal and state laws of the United States of America or of any other jurisdiction whose laws may be mandatorily applicable to such Lender or Agent notwithstanding anything to the contrary in this Agreement or any other Loan Document) then, in that event, notwithstanding anything to the contrary in this Agreement or any other Loan Document, it is agreed as follows: (a) the provisions of this Section shall govern and control; (b) the aggregate of all consideration which constitutes interest under applicable law that is contracted for, taken, reserved, charged or received under this Agreement, or under any of the aforesaid agreements or otherwise in connection with this Agreement or any other Loan Document by such Lender or Agent shall under no circumstances exceed the maximum amount of interest allowed by applicable law (such maximum lawful interest rate, if any, with respect to each Lender and each Agent herein called the "Maximum Lawful Rate"), and any excess shall be canceled automatically and if theretofore paid shall be credited to the relevant Designated Entity by such Lender or Agent (or, if such consideration shall have been paid in full, such excess refunded to the relevant Designated Entity); (c) all sums paid, or agreed to be paid, to such Lender or Agent for the use, forbearance and detention of the indebtedness of the relevant Designated Entity 70 75 to such Lender or Agent hereunder or under any other Loan Document shall, to the extent permitted by laws applicable to such Lender or Agent, as the case may be, be amortized, prorated, allocated and spread throughout the full term of such indebtedness until payment in full so that the actual rate of interest is uniform throughout the full term thereof; (d) if at any time the interest provided pursuant to any provision of this Agreement or any other Loan Document, together with any other fees payable pursuant to this Agreement or any other Loan Document and deemed interest under laws applicable to such Lender or Agent, exceeds the amount which would have accrued at the Maximum Lawful Rate, the amount of interest and any such fees to accrue to such Lender or Agent pursuant to this Agreement or any other Loan Document shall be limited, notwithstanding anything to the contrary in this Agreement or any other Loan Document, to that amount which would have accrued at the Maximum Lawful Rate, but any subsequent reductions, as applicable, shall not reduce the interest to accrue to such Lender or Agent pursuant to this Agreement or any other Loan Document below the Maximum Lawful Rate until the total amount of interest accrued pursuant to this Agreement or such other Loan Document, as the case may be, and such fees deemed to be interest equals the amount of interest which would have accrued to such Lender or Agent if a varying rate of interest per annum equal to the interest provided pursuant to Section 2.3 or any other relevant Section hereof (other than this Section) and the Notes, as applicable, had at all times been in effect, plus the amount of fees which would have been received but for the effect of this Section; and (e) if the total amount of interest paid by or accrued with respect to the Obligations of Borrower, together with any other fees payable pursuant to this Agreement and the other Loan Documents and deemed interest under laws applicable to such Lender or Agent pursuant to this Agreement or any other Loan Document under the foregoing provisions of this Section is less than the total amount of interest which would have accrued if a varying rate per annum equal to the interest provided pursuant to Section 2.3 or any other relevant section hereof (other than this Section), as applicable, had at all times been in effect and all fees provided for in this Agreement and the other Loan Documents had been paid, then Borrower severally agrees to pay to such Lender or Agent an amount equal to the difference between, (i) the lesser of, (x) the amount of interest and fees which would have accrued if the Maximum Lawful Rate had at all times been in effect, and (y) the amount of interest and fees which would have accrued if a varying rate per annum equal to the interest provided pursuant to Section 2.3 or such other relevant section of this Agreement (other than this Section) and the Notes, as applicable, had at all times been in effect and all fees had been 71 76 paid, and (ii) the amount of interest and fees accrued in accordance with the other provisions of this Agreement and other Loan Documents. For purposes of Chapter 1D of Article 5069 of the Texas Credit Title, Title 79, Vernon's Texas Civil Statutes, as amended (formerly Article 5069-1.04, Vernon's Texas Civil Statutes, as amended), to the extent, if any, applicable to any Lender or Agent, Borrower and each other Designated Entity agrees that the Maximum Lawful Rate shall be the "applicable interest rate ceiling" as defined in said Chapter, provided that such Lender or Agent, as applicable, may also rely, to the extent permitted by applicable laws of the State of Texas and the United States of America, on alternative maximum rates of interest under other laws applicable to such Lender or Agent from time to time if greater. Section 8.7 Termination; Limited Survival. In its sole and absolute discretion, Borrower may, at any time that no Obligations or other amounts are owing, elect to terminate this Agreement in a written notice delivered to Administrative Agent. Upon receipt by Administrative Agent of such a notice, if no Obligations or other amounts are then owing, this Agreement and all other Loan Documents shall thereupon be terminated and the parties thereto released from all prospective obligations hereunder or thereunder. Notwithstanding the foregoing or anything herein to the contrary, any waivers or admissions made by any Designated Entity in any Loan Document, any Obligations under Sections 2.16 through 2.20, any obligations which any Designated Entity may have to indemnify or compensate any Agent, or any Lender in connection with matters arising upon or prior to the termination of this Agreement and any obligations which any Lender may have to indemnify or compensate any Agent in connection with matters arising upon or prior to the termination of this Agreement shall survive any termination of this Agreement or any other Loan Document and the release of Designated Entities. At the request and expense of Borrower, Managing Agents shall prepare and execute all necessary instruments to reflect and effect such termination of the Loan Documents including, without limitation, the Security Instruments.

If the undersigned fails to pay any Taxes or Stamp Taxes when due to the appropriate taxing authority or fails to remit to Administrative Agent, for the account of the respective Lenders, the required receipts or other required documentary evidence, the undersigned shall indemnify Lenders for any Taxes, interest or penalties that may become payable by any Lender as a result of any such failure, subject to the provisions of Section 2.9.

[SECTION 2.10. Judgment. Guarantor hereby agrees that: (a) If, for the purposes of obtaining judgment in any court, it is necessary to convert a sum due hereunder in United States Dollars into another currency, Guarantor agrees, to the fullest extent permitted by law, that the rate of exchange used shall be that at which in accordance with normal banking procedures the Administrative Agent could purchase United States Dollars with such other currency on the Business Day preceding that on which final judgment is given. (b) The obligation of Guarantor in respect of any sum due from it to any Lender Party or any holder of a Note hereunder shall, notwithstanding any judgment in a currency other than United States Dollars, be discharged only to the extent that on the Business Day following receipt by such Lender Party or such holder, as the case may be, of any sum adjudged to be so due in such other currency such Lender Party or such holder, as the case may be, may, in accordance with normal banking procedures, purchase United States Dollars with such other currency; in the event that the United States Dollars so purchased are less than the sum originally due to such Lender Party in United States Dollars, Guarantor, as a separate obligation and notwithstanding any such judgment, hereby indemnifies and holds harmless such Lender Party and such holder against such loss, and if the United States Dollars so purchased exceed the sum originally due to such Lender Party or such holder in United States Dollars, such Lender Party or such holder, as the case may be, shall remit to Guarantor such excess.] Exhibit B - 10 128 ARTICLE III REPRESENTATIONS AND WARRANTIES SECTION 3.1.

The powers conferred on Collateral Agent hereunder are solely to protect its interest (on behalf of Lender Parties) in the Collateral and shall not impose any duty on it to exercise any such powers.

SECTION 5.4. Reasonable Care. Collateral Agent is required to exercise reasonable care in the custody and preservation of any of the Collateral in its possession; provided, however, Collateral Agent shall be deemed to have exercised reasonable care in the custody and preservation of any of the Collateral, if it takes such action for that purpose as Pledgor reasonably requests in writing at times other than upon the occurrence and during the continuance of any Event of Default, but failure of Collateral Agent to comply with any such request at any time shall not in itself be deemed a failure to exercise reasonable care. ARTICLE VI REMEDIES SECTION 6.1. Certain Remedies. On or after any acceleration under the Credit Agreements or Default occurring on the Maturity Date: (a) Collateral Agent may exercise in respect of the Collateral, in addition to other rights and remedies provided for herein or otherwise available to it, all the rights and remedies of a secured party on default under the U.C.C. (whether or not the U.C.C. applies to the affected Collateral) and also may, without notice except as specified below, sell the Collateral or any part thereof in one or more parcels at public or private sale, at any of Collateral Agent's offices or elsewhere, for cash, on credit or for future delivery, and upon such other terms as Collateral Agent may deem commercially reasonable. Pledgor agrees that, to the extent notice of sale shall be required by law, Exhibit M - 12 168 at least ten days' prior notice to Pledgor of the time and place of any public sale or the time after which any private sale is to be made shall constitute reasonable notification. Collateral Agent shall not be obligated to make any sale of Collateral regardless of notice of sale having been given. Collateral Agent may adjourn any public or private sale from time to time by announcement at the time and place fixed therefor, and such sale may, without further notice, be made at the time and place to which it was so adjourned.

SECTION 6.2. Compliance with Restrictions. Pledgor agrees that in any sale of any of the Collateral whenever an Event of Default shall have occurred and be continuing, Collateral Agent is hereby authorized to comply with any limitation or restriction in connection with such sale as it may be advised by counsel is necessary in order to avoid any violation of applicable law (including compliance with such procedures as may restrict the number of prospective bidders and purchasers, require that such prospective bidders and purchasers have certain qualifications, and restrict such prospective bidders and purchasers to persons who will represent and agree that they are purchasing for their own account for investment and not with a view to the distribution or resale of such Collateral), or in order to obtain any required approval of the sale or of the purchaser by any governmental regulatory authority or official, and Pledgor further agrees that such compliance shall not result in such sale being considered or deemed not to have been made in a commercially reasonable manner, nor shall Collateral Agent be liable nor accountable to Pledgor for any discount allowed by the reason of the fact that such Collateral is sold in compliance with any such limitation or restriction. Exhibit M - 13 169 SECTION 6.3. Application of Proceeds. All cash proceeds received by Collateral Agent in respect of any sale of, collection from, or other realization upon, all or any part of the Collateral may, in the discretion of Collateral Agent, be held by Collateral Agent as additional collateral security for, or then or at any time thereafter be applied (after payment of any amounts payable to Collateral Agent pursuant to Sections 6.4 of the Credit Agreements) in whole or in part by Collateral Agent against, all or any part of the Secured Obligations in such order as Collateral Agent shall elect. Any surplus of such cash or cash proceeds held by Collateral Agent and remaining after payment in full of all the Secured Obligations, and the termination of all Commitments, shall be paid over to Pledgor or to whomsoever may be lawfully entitled to receive such surplus. SECTION 6.4. Indemnity and Expenses. Pledgor hereby indemnifies and holds harmless Collateral Agent in accordance with Sections 6.4 of the Credit Agreements. ARTICLE VII MISCELLANEOUS PROVISIONS SECTION 7.1. Loan Document.

SECTION 7.2. Amendments.

SECTION 7.3. Protection of Collateral.
