NATIONAL-OILWELL, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED) 1. BASIS OF PRESENTATION The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect reported and contingent amounts of assets and liabilities as of the date of the financial statements and reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. The accompanying unaudited consolidated financial statements present information in accordance with accounting principles generally accepted in the United States for interim financial information and the instructions to Form 10-Q and applicable rules of Regulation S-X. They do not include all information or footnotes required by accounting principles generally accepted in the United States for complete financial statements and should be read in conjunction with our 2001 Annual Report on Form 10-K. In our opinion, the consolidated financial statements include all adjustments, all of which are of a normal, recurring nature, necessary for a fair presentation of the results for the interim periods. The results of operations for the three months and nine months ended September 30, 2002 and 2001 may not be indicative of results for the full year. 2. ACQUISITIONS On January 10, 2002, we completed the acquisition of the assets and business of HAL Oilfield Pump & Equipment Company ("Halco") for $15.4 million. This business, which designs, manufactures and distributes centrifugal pumps, pump packages and expendable parts, is complementary to our Mission pump product line. The acquisition was accounted for as a purchase with goodwill approximating $10.0 million. We made nine acquisitions in 2001, ranging in value from $600,000 to a high of $16.5 million, for a total cash outlay of $51.5 million. All of these acquisitions were accounted for under the purchase method of accounting and generated approximately $30 million in goodwill. Two of the larger acquisitions, Integrated Power Systems and Maritime Hydraulics (Canada) Ltd., were acquired in early January 2001 and their financial results were included in our consolidated financial results for substantially the entire year. Pro-forma information related to acquisitions has not been provided as such amounts are not material individually or in the aggregate. 3.

It is available for acquisitions and general corporate purposes and provides up to $50 million for letters of credit, of which $22.0 million were outstanding at September 30, 2002. Interest is based upon prime or Libor plus 0.5% subject to a ratings based grid. In securing this new credit facility we incurred approximately $0.9 million in fees which will be amortized to expense over the term of the facility. We also have additional credit facilities totaling $70 million that are used primarily for letters of credit. Borrowings against these credit facilities totaled $9.8 million at September 30, 2002, essentially all applicable to letters of credit. The senior notes contain reporting covenants and the credit facility contains financial covenants and ratios regarding maximum debt to capital and minimum interest coverage. At September 30, 2002, the Company was in compliance with all covenants governing these facilities. 7. RECENTLY ISSUED ACCOUNTING STANDARDS On January 1, 2002, we adopted Statement of Financial Accounting Standards No. 142, Goodwill and Other Intangible Assets ("SFAS No. 142"). Under the new rules, goodwill and intangible assets deemed to have indefinite lives will no longer be amortized but will be subject to annual impairment tests in accordance with SFAS No. 142. Other intangible assets will continue to be amortized over their useful lives. During the second quarter of 2002, we completed the first of the required impairment tests of goodwill and indefinite lived assets, which indicated no impairment was required as of January 1, 2002. The following information provides net income for the three-month and nine-month period ended September 30, 2001 adjusted to exclude amortization expense recognized in this period related to goodwill (in thousands): 6

This statement supercedes SFAS No. 121, Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to be Disposed Of, and the accounting and reporting provisions of Accounting Principles Board Opinion ("APB") No. 30, Reporting the Results of Extraordinary, Unusual, and Infrequently Occurring Events and Transactions. This statement retains the fundamental provisions of SFAS No. 121 and the basic requirements of APB No. 30; however, it establishes a single accounting model to be used for long-lived assets to be disposed of by sale and it expands the presentation of discontinued operations to include more disposal transactions. The provisions of this statement are effective for financial statements issued for fiscal years beginning after December 15, 2001. Adoption of this statement did not have a material impact on our financial position or results of operations. In July, 2002, the Financial Accounting Standards Board issued SFAS No. 146, Accounting for Costs Associated with Exit or Disposal Activities. This statement addresses financial accounting and reporting for costs associated with exit or disposal activities, such as restructuring, involuntarily terminating employees, and consolidating facilities, initiated after December 31, 2002. We do not believe the adoption of this new statement will have a material impact on our consolidated financial statements. 8. SUBSEQUENT EVENT On October 11, 2002, we announced the signing of a definitive agreement to acquire all of the outstanding shares of Hydralift ASA, a Norwegian oilfield service company. On November 8, 2002 we made a cash Tender Offer of NOK 55, approximately U.S. $7.33, for each share of Hydralift. The total value of the transaction, including the assumption of debt, is approximately $300 million. The transaction is subject to various conditions, including certain regulatory approvals, and the acceptance of the Tender Offer by shareholders owning more than 90% of the outstanding shares. 7

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS INTRODUCTION National Oilwell is a worldwide leader in the design, manufacture and sale of comprehensive systems and components used in oil and gas drilling and production, as well as in providing supply chain integration services to the upstream oil and gas industry. Our revenues are directly related to the level of worldwide oil and gas drilling and production activities and the profitability and cash flow of oil and gas companies and drilling contractors, which in turn are affected by current and anticipated prices of oil and gas. Oil and gas prices have been volatile since 1990, ranging from $10 - $40 per barrel. Oil prices were low in 1998, generally ranging from $11 - $16 per barrel. In 1999, oil prices increased and were generally in the $25 - $30 per barrel range during 2000. Prices once again declined in the second half of 2001, generally ranging between $18 and $22. Then, since the second quarter of 2002, oil has generally ranged from $25 - $30 per barrel. Spot gas prices have also been volatile since 1990, ranging from less than $1.00 per mmbtu to above $10.00. Gas prices were moderate in 1998 and 1999, generally ranging from $1.80 - $2.50 per mmbtu. Gas prices strengthened throughout 2000, generally ranging from $4 - $8 per mmbtu. In the second quarter of 2001, gas prices again came under pressure, and generally ranged from $2.20 - $3.00 per mmbtu through the first quarter of 2002. Gas prices increased in the second quarter of 2002 and have generally ranged between $3 - $4 per mmbtu since then. We conduct our operations through the following segments: Products and Technology The Products and Technology segment manufactures and assembles drilling machinery, including drawworks, mud pumps and top drives, which are the major mechanical components of drilling rigs, as well as masts, derricks, cranes and substructures. Many of these components are designed specifically for more demanding applications, which include offshore, extended reach and deep land drilling. We also provide electrical power systems, computer control systems and automation systems for drilling rigs. Our systems are used in many of the industry's most technologically demanding applications. In addition, we provide engineering and fabrication services to integrate our drilling products and deliver complete land drilling and workover rigs as well as drilling modules for mobile offshore drilling rigs or offshore drilling platforms. A substantial installed base of these products results in a recurring replacement parts and maintenance business. Sales of new capital equipment can result in large fluctuations in volume between periods depending on the size and timing of the shipment of orders. This segment also designs and manufactures drilling motors and specialized downhole tools for rent and sale. Drilling motors are essential components of systems for horizontal, directional, extended reach and performance drilling. Downhole tools include fishing tools, drilling jars, shock tools and other specialized products. Distribution Services Our Distribution Services segment offers comprehensive supply chain integration services to the drilling and production segments. Our network of service centers located in the United States and Canada and near other major drilling and production activity worldwide use state of the art information technology platforms to provide procurement, inventory management and logistics services. These service centers stock and sell a variety of expendable items for oilfield applications and spare parts for equipment manufactured by National Oilwell. 8

RESULTS OF OPERATIONS Operating results by segment are as follows (in thousands): Quarter Ended September 30, Nine Months Ended September 30, ----------------------------- --------------------------------- 2002 2001 2002 2001 ----------- ----------- ------------- ------------- Revenues Products and Technology $ 213,067 $ 317,017 $ 679,162 $ 814,073 Distribution Services 175,616 193,569 511,980 532,280 Eliminations (21,754) (23,774) (62,837) (64,641) --------- --------- ----------- ----------- Total $ 366,929 $ 486,812 $ 1,128,305 $ 1,281,712 ========= ========= =========== =========== Operating Income Products and Technology $ 30,241 $ 50,413 $ 95,758 $ 124,542 Distribution Services 4,508 9,244 13,790 23,052 Corporate (2,847) (2,755) (7,693) (7,672) --------- --------- ----------- ----------- Total $ 31,902 $ 56,902 $ 101,855 $ 139,922 ========= ========= =========== =========== Products and Technology Q3 2002 versus Q3 2001 Revenues for the Products and Technology segment decreased by one-third, or $104 million, during the third quarter of 2002 as compared to the same quarter in 2001 as lower drilling activity in the Western Hemisphere markets impacted all product lines. Capital equipment revenues fell $54 million and drilling spare part sales were down $14 million, reflecting the lower number of rigs operating in the United States. Revenues of electrical power systems and other rig control systems fell approximately $7 million. Sales of Mission expendable pump parts and centrifugal pumps and packages declined $7 million (20%) in the quarter when compared to the same quarter in the prior year. The downhole motors and tools business experienced a 39% decline in revenue, reflecting the reduced activity in the Canadian marketplace. Operating income decreased by $20 million in the third quarter of 2002 compared to the same quarter in 2001 due principally to the lower revenue volume, offset in part by the exclusion of goodwill amortization ($2.7 million in the third quarter of 2001), as required by the new accounting standard "SFAS No. 142". 1st nine months 2002 versus 1st nine months 2001 Products and Technology segment revenues declined $135 million in the first nine months of 2002 as compared to the same period in 2001. This 17% decrease was a direct result of lower rig activity in North America, which is a key driver of sales of drilling spare parts, pump expendable parts and downhole tools and motors. All product lines reported lower revenues during the first half of 2002 when compared to 2001. Operating income decreased $29 million in the first nine months of 2002 compared to the same period last year due principally to the lower margin resulting from the reduced revenue volume and increases in selling expenses and agent commissions. Reduced spending in field operations and plant shipping expenses and a reduction of $7.9 million in goodwill amortization (amortization is no longer required by the new accounting standard "SFAS No. 142") offset a portion of the margin shortfall. 9

Backlog of the Products and Technology capital products was $231 million at September 30, 2002, down $47 million from the June 30, 2002 balance of $278 million. Backlog at December 31, 2001 and September 30, 2001 was $385 million and $453 million, respectively. Approximately 40% of the product in current backlog will be delivered during the fourth quarter of 2002 with the remainder during 2003. Distribution Services Q3 2002 versus Q3 2001 Distribution Services revenues decreased $18 million during the second quarter of 2002 over the comparable 2001 period. Lower market activity in North America was the key driver of this 9% decrease. Tubular revenues were $2 million lower when compared to the second quarter of 2001 while revenues from the sale of parts manufactured by the Products & Technology segment increased by $2 million. Maintenance, repair and operating supplies revenues declined approximately $18 million (11%). Operating income in the third quarter of 2002 was approximately half of the third quarter of the prior year results, principally due to the lower revenue volume, a 1-point reduction in gross margin percent due to the highly competitive North American marketplace and higher infrastructure expenses to cover our expanded international market. 1st nine months 2002 versus 1st nine months 2001 Revenues for the Distribution Services segment decreased $20 million in the first nine months of 2002 when compared to the prior year. Revenue increases in the international market were offset by decreases in both the U.S. and Canadian operations. Revenues from the sale of parts manufactured by the Products & Technology segment were up $7 million (11%) while the maintenance, repair and operating supplies revenues reflected a 5% decline from the first nine months of 2001. Tubular revenues were lower by approximately one-third, or $6 million. Operating income in the first nine months of 2002 of $14 million was approximately $9 million lower than the comparable period in 2001. Gross margin accounted for roughly $6 million of the decline due to the lower sales volume and a decline in base margin percent in the U.S. and international operations. Significant infrastructure growth and ongoing e-commerce initiatives account for the remaining decline in operating profit in the first nine months of 2002 when compared to 2001. Excluding goodwill amortization, as required under the new accounting standard "SFAS No. 142", operating income in the third quarter and first nine months of 2001 would have increased $0.4 million and $0.9 million, respectively. Corporate Corporate charges represent the unallocated portion of centralized and executive management costs. These costs increased approximately $0.3 million during the quarter, in part due to corporate marketing initiatives. Spending was flat for the nine months ending September 30, 2002 when compared to the same time period in the prior year. Interest Expense Interest expense decreased slightly during the three months ended September 30, 2002 as compared to the prior year due to a lower average debt level during the period. For the first nine months of 2002, interest expense was lower than the previous year by $0.6 million due to both reduced borrowings and reduced rates. Other financial costs, principally bank fees related to letters of credit and performance 10

bonds, increased during the three and nine month periods ending September 30, 2002 when compared to the same period of the prior year, reflecting our increased international activity. LIQUIDITY AND CAPITAL RESOURCES At September 30, 2002 we had working capital of $685 million, an increase of $54 million from December 31, 2001 primarily due to cash generated from operations and a $28 million reduction in receivables, reflecting the overall weaker market environment during 2002. Inventory remained virtually flat as decreases in both raw material and finished goods were offset by increases in work-in-process. Total capital expenditures were $14 million during the first nine months of 2002 compared to $22 million in the first nine months of the prior year. Enhancements to information management systems and additions to the downhole rental tool fleet represent the majority of these capital expenditures. We believe we have sufficient existing manufacturing capacity to meet currently anticipated demand through 2003 for our products and services. On July 30, 2002, we replaced the existing credit facility with a new three-year unsecured $175 million revolving credit facility. It is available for acquisitions and general corporate purposes and provides up to $50 million for letters of credit, of which $22.0 million were outstanding at September 30, 2002. Interest is based upon prime or Libor plus 0.5% subject to a ratings based grid. In securing this new credit facility we incurred approximately $0.9 million in fees which will be amortized to expense over the term of the facility. We also have additional credit facilities totaling $70 million that are used primarily for letters of credit. Borrowings against these credit facilities totaled $9.8 million at September 30, 2002, essentially all applicable to letters of credit. The senior notes contain reporting covenants and the credit facility contains financial covenants and ratios regarding maximum debt to capital and minimum interest coverage. At September 30, 2002 and December 31, 2001, the Company was in compliance with all covenants governing these facilities. We believe cash generated from operations and amounts available under the credit facilities and from other sources of debt will be sufficient to fund operations, working capital needs, capital expenditure requirements and financing obligations. We also believe any significant increase in capital expenditures caused by any need to increase manufacturing capacity can be funded from operations or through debt financing. We have not entered into any transactions, arrangements, or relationships with unconsolidated entities or other persons which would materially affect liquidity, or the availability of or requirements for capital resources. We intend to pursue additional acquisition candidates, but the timing, size or success of any acquisition effort and the related potential capital commitments cannot be predicted. We expect to fund future cash acquisitions primarily with cash flow from operations and borrowings, including the unborrowed portion of the credit facility or new debt issuances, but may also issue additional equity either directly or in connection with acquisitions. There can be no assurance that additional financing for acquisitions will be available at terms acceptable to us. 11

CRITICAL ACCOUNTING POLICIES AND ESTIMATES The preparation of our financial statements requires us to make certain estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Our estimation process generally relates to potential bad debts, obsolete and slow moving inventory, value of intangible assets, and deferred income tax accounting. Our estimates are based on historical experience and on our future expectations that we believe to be reasonable under the circumstances. The combination of these factors result in the amounts shown as carrying values of assets and liabilities in the financial statements and accompanying notes. Actual results could differ from our current estimates and those differences may be material. We believe the following accounting policies are the most critical in the preparation of our consolidated financial statements: We maintain an allowance for doubtful accounts for accounts receivables by providing for specifically identified accounts where collectibility is doubtful and a general allowance based on the aging of the receivables compared to past experience and current trends. A majority of our revenues come from drilling contractors, independent oil companies, international oil companies and government-owned or government-controlled oil companies, and we have receivables, some denominated in local currency, in many foreign countries. If, due to changes in worldwide oil and gas drilling activity or changes in economic conditions in certain foreign countries, our customers were unable to repay these receivables, additional allowances would be required. Reserves for inventory obsolescence are determined based on our historical usage of inventory on-hand as well as our future expectations related to our substantial installed base and the development of new products. The amount reserved is the recorded cost of the inventory minus its estimated realizable value. Changes in worldwide oil and gas drilling activity and the development of new technologies associated with the drilling industry could require additional allowances to reduce the value of inventory to the lower of its cost or net realizable value. Business acquisitions are accounted for using the purchase method of accounting. The cost of the acquired company is allocated to identifiable tangible and intangible assets based on estimated fair value, with the excess allocated to goodwill. The determination of impairment on long-lived assets, including goodwill, is conducted as indicators of impairment are present. If such indicators were present, the determination of the amount of impairment would be based on our judgments as to the future operating cash flows to be generated from these assets throughout their estimated useful lives. Our industry is highly cyclical and our estimates of the period over which future cash flows will be generated, as well as the predictability of these cash flows, can have a significant impact on the carrying value of these assets. In periods of prolonged down cycles, impairment charges may result. Our net deferred tax assets and liabilities are recorded at the amount that is more likely than not to be realized or paid. Should we determine that we would not be able to realize all or part of the net deferred tax asset in the future, an adjustment to the deferred tax assets would be charged to income in the period of such determination. 12

RECENTLY ISSUED ACCOUNTING STANDARDS On January 1, 2002, we adopted Statement of Financial Accounting Standards No. 142, Goodwill and Other Intangible Assets ("SFAS No. 142"). Under the new rules, goodwill and intangible assets deemed to have indefinite lives will no longer be amortized but will be subject to annual impairment tests in accordance with SFAS No. 142. Other intangible assets will continue to be amortized over their useful lives. During the second quarter of 2002, we completed the first of the required impairment tests of goodwill and indefinite lived assets, which indicated no impairment was required as of January 1, 2002. The following information provides net income for the three-month and nine-month period ended September 30, 2001 adjusted to exclude amortization expense recognized in this period related to goodwill (in thousands): Quarter ended Nine months ended September 30, 2001 September 30, 2001 ---------------------- ---------------------- Reported net income $ 28,938 $ 75,715 Add back: Goodwill amortization, net of tax 2,819 8,243 -------- -------- Adjusted net income $ 31,757 $ 83,958 Adjusted net income per share: Basic $ 0.39 $ 1.04 Diluted $ 0.39 $ 1.03 Weighted average shares outstanding: Basic 80,887 80,787 Diluted 81,437 81,834 In August 2001, the FASB issued SFAS No. 144, Accounting for the Impairment or Disposal of Long-Lived Assets. This statement supercedes SFAS No. 121, Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to be Disposed Of , and the accounting and reporting provisions of Accounting Principles Board Opinion ("APB") No. 30, Reporting the Results of Extraordinary, Unusual, and Infrequently Occurring Events and Transactions. This statement retains the fundamental provisions of SFAS No. 121 and the basic requirements of APB No. 30; however, it establishes a single accounting model to be used for long-lived assets to be disposed of by sale and it expands the presentation of discontinued operations to include more disposal transactions. The provisions of this statement are effective for financial statements issued for fiscal years beginning after December 15, 2001. Adoption of this statement did not have a material impact on our financial position or results of operations. In July, 2002, the Financial Accounting Standards Board issued SFAS No. 146, Accounting for Costs Associated with Exit or Disposal Activities. This statement addresses financial accounting and reporting for costs associated with exit or disposal activities, such as restructuring, involuntarily terminating employees, and consolidating facilities, initiated after December 31, 2002. We do not believe the adoption of this new statement will have a material impact on our consolidated financial statements. SUBSEQUENT EVENT On October 11, 2002, we announced the signing of a definitive agreement to acquire all of the outstanding shares of Hydralift ASA, a Norwegian oilfield service company. On November 8, 2002 we made a cash Tender Offer of NOK 55, approximately U.S. $7.33, for each share of Hydralift. The total 13

value of the transaction, including the assumption of debt, is approximately $300 million. The transaction is subject to various conditions, including certain regulatory approvals, and the acceptance of the Tender Offer by shareholders owning more than 90% of the outstanding shares. FORWARD-LOOKING STATEMENTS This document, other than historical financial information, contains forward-looking statements that involve risks and uncertainties. Such statements relate to our revenues, sales of capital equipment, backlog, capacity, liquidity and capital resources and plans for acquisitions and any related financings. Readers are referred to documents filed by us with the Securities and Exchange Commission which identify significant risk factors which could cause actual results to differ from those contained in the forward-looking statements, including "Risk Factors" at Item 1 of the Annual Report on Form 10-K. Given these uncertainties, current or prospective investors are cautioned not to place undue reliance on any such forward-looking statements. We disclaim any obligation or intent to update any such factors or forward-looking statements to reflect future events or developments. ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK There has been no material change during 2002 in our market risk, as disclosed in our 2001 Annual Report on Form 10-K. ITEM 4. CONTROLS AND PROCEDURES Within 90 days before filing this report, we carried out an evaluation, under the supervision and with the participation of the company's management, including the company's President and Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of the company's disclosure controls and procedures. Based upon that evaluation, the company's President and Chief Executive Officer along with the company's Chief Financial Officer concluded that the company's disclosure controls and procedures are effective in timely alerting them to material information relating to the company (including its consolidated subsidiaries) required to be included in the company's periodic Securities and Exchange Commission filings. There have been no significant changes in our internal controls or in other factors that could significantly affect these controls subsequent to the date of our evaluation. 14

III. EFFECTIVE DATE AND DURATION OF THE PLAN The Plan shall be effective upon the date of its adoption by the Board, provided the Plan is approved by the stockholders of the Company within twelve months thereafter.

During the term of the Plan, the maximum aggregate number of shares of Common Stock that shall be subject to Awards under the Plan to any individual shall not exceed one-half of the aggregate limitation for the Plan specified in the preceding sentence. Any of such shares which remain unissued and which are not subject to outstanding Awards at the termination of the Plan shall cease to be subject to the Plan, but, until termination of the Plan, the Company shall at all times reserve a sufficient number of shares to meet the requirements of the Plan. Shares shall be deemed to have been issued under the Plan only to the extent actually issued and delivered pursuant to an Award. To the extent that an Award lapses or the rights of its Holder terminate any shares of Common Stock subject to such Award shall again be available for the grant of an Award. The aggregate number of shares which may be issued under the Plan shall be subject to adjustment in the same manner as provided in Article XIII with respect to shares of Common Stock subject to Options then outstanding. Separate stock certificates shall be issued by the Company for those shares acquired pursuant to the exercise of an Incentive Stock Option and for those shares acquired pursuant to the exercise of a Nonqualified Option. (b) STOCK OFFERED. The stock to be offered pursuant to the grant of an Award may be authorized but unissued Common Stock or Common Stock previously issued and outstanding and, reacquired by the Company. VI. ELIGIBILITY 23

Awards made pursuant to the Plan may be granted only to individuals who, at the time of grant, are key employees or directors of the Company or any Parent Corporation or Subsidiary of the Company. Awards may not be granted to any director of the Company who is not an employee of the Company or to any member of the Committee provided, however, that effective August 28, 1996, Awards, other than Incentive Stock Options, may be granted to directors who are not employees of the Company. Awards, other than Incentive Stock Options, may also be granted to consultants who are not employees of the Company. An Award made pursuant to the Plan may be granted on more than one occasion to the same person, and such Award may include an Incentive Stock Option, a Nonqualified Option, an Award of Stock Appreciation Rights, a Restricted Stock Award, a Performance Share Award, a Stock Value Equivalent Award or any combination thereof. Each Award shall be evidenced by a written instrument duly executed by or on behalf of the Company. VII. OPTIONS (a) OPTION AGREEMENT. Each Option shall be evidenced by an Option Agreement between the Company and the Optionee which shall contain such terms and conditions as may be approved by the Committee. The terms and conditions of the respective Option Agreements need not be identical. Specifically, an Option Agreement may provide for the payment of the option price, in whole or in part, by the delivery of a number of shares of Common Stock (plus cash if necessary) having a Fair Market Value equal to such option price or payment through a broker in accordance with procedures permitted by Regulation T of the Federal Reserve Board. Each Option Agreement shall provide that the Option may not be exercised earlier than six months from the date of grant and shall specify the effect of termination of employment on the exercisability of the Option. (b) OPTION PERIOD. The term of each Option shall be as specified by the Committee at the date of grant provided, however, that the term of any Incentive Stock Option shall not exceed ten years. (c) LIMITATIONS ON EXERCISE OF OPTION. An Option shall be exercisable in whole or in such installments and at such times as determined by the Committee. (d) SPECIAL LIMITATIONS ON INCENTIVE STOCK OPTIONS. To the extent that the aggregate Fair Market Value (determined at the time the respective Incentive Stock Option is granted) of Common Stock with respect to which Incentive Stock Options are exercisable for the first time by an individual during any calendar year under all incentive stock option plans of the Company and its Parent Corporation and Subsidiaries exceeds $100,000, such excess Incentive Stock Options shall be treated as Nonqualified Options. The Committee shall determine, in accordance with applicable provisions of the Code, Treasury Regulations and other administrative pronouncements, which of an Optionee's Incentive Stock Option will not constitute Incentive Stock Options because of such limitation and shall notify the Optionee of such determination as soon as practicable after such determination. No Incentive Stock Option shall be granted to an individual if, at the time the Option is granted, such individual owns stock possessing more than 10% of the total combined voting power of all classes of stock of the Company or of its Parent Corporation or a Subsidiary, within the meaning of section 422(b)(6) of the Code, unless (1) at the time such Option is granted the option price is at least 110% of the Fair Market Value of the Common Stock subject to the 24

Option and (ii) such Option by its terms is not exercisable after the expiration of five years from the date of grant. (e) OPTION PRICE. The purchase price of Common Stock issued under each Option shall be determined by the Committee, but such purchase price shall not be less than the Fair Market Value of Common Stock subject to the Option on the date the Option is granted. (f) OPTIONS AND RIGHTS IN SUBSTITUTION FOR STOCK OPTIONS GRANTED BY OTHER CORPORATIONS. Options and Stock Appreciation Rights may be granted under the Plan from time to time in substitution for stock options held by employees of corporations who become, or who became prior to the effective date of the Plan, key employees of the Company or of any Subsidiary as a result of a merger or consolidation of the employing corporation with the Company or such Subsidiary, or the acquisition by the Company or a Subsidiary of all or a portion of the assets of the employing corporation, or the acquisition by the Company or a Subsidiary of stock of the employing corporation with the result that such employing corporation becomes a Subsidiary. VIII. STOCK APPRECIATION RIGHTS (a) STOCK APPRECIATION RIGHTS. A Stock Appreciation Right is the right to receive an amount equal to the Spread with respect to a share of Common Stock upon the exercise of such Stock Appreciation Right. Stock Appreciation Rights may be granted in connection with the grant of an Option, in which case the Option Agreement will provide that exercise of Stock Appreciation Rights will result in the surrender of the right to purchase the shares under the Option as to which the Stock Appreciation Rights were exercised. Alternatively, Stock Appreciation Rights granted independently of Options in which case each Award of Stock Appreciation Rights shall be evidenced by a Stock Appreciation Rights Agreement between the Company and the Holder which shall contain such terms and conditions as may be approved by the Committee. The terms and conditions of the respective Stock Appreciation Rights Agreements need not be identical. The Spread with respect to a Stock Appreciation Right may be payable either in cash, shares of Common Stock with a Fair Market Value equal to the Spread or in a combination of cash and shares of Common Stock. Upon the exercise of any Stock Appreciation Rights granted hereunder, the number of shares reserved for issuance under the Plan shall be reduced only to the extent that shares of Common Stock are actually issued in connection with the exercise of such Stock Appreciation Right. Each Stock Appreciation Rights Agreement shall provide that the Stock Appreciation Rights may not be exercised earlier than six months from the date of grant and shall specify the effect of termination of employment on the exercisability of the Stock Appreciation Rights. (b) EXERCISE PRICE. The exercise price of each Stock Appreciation Right shall be determined by the Committee, but such exercise price shall not be less than the Fair Market Value of a share of Common Stock on the date the Stock Appreciation Right is granted. (c) EXERCISE PERIOD. The term of each Stock Appreciation Right shall be as specified by the Committee at the date of grant. 25

(d) LIMITATIONS ON EXERCISE OF STOCK APPRECIATION RIGHT. A Stock Appreciation Right shall be exercisable in whole or in such installments and at such times as determined by the Committee. IX. RESTRICTED STOCK AWARDS (a) RESTRICTION PERIOD TO BE ESTABLISHED BY THE COMMITTEE. At the time a Restricted Stock Award is made, the Committee shall establish a period of time (the "Restriction Period") applicable to such Award. Each Restricted Stock Award may have a different Restriction Period, as determined in the discretion of the Committee. The Restriction Period applicable to a particular Restricted Stock Award shall not be changed except as permitted by Paragraph (b) of this Article. (b) OTHER TERMS AND CONDITIONS. Common Stock awarded pursuant to a Restricted Stock Award shall be represented by a stock certificate registered in the name of the Holder of such Restricted Stock Award or, at the option of the Company, in the name of a nominee of the Company. The Holder shall have the right to receive dividends during the Restriction Period (subject to the terms of any Restricted Stock Agreement), to vote the Common Stock subject thereto and to enjoy all other stockholder rights (subject to the terms of any Restricted Stock Agreement), except that unless otherwise specified in the Restricted Stock Agreement (i) the Holder shall not be entitled to possession of the stock certificate until the Restriction Period shall have expired, (ii) at the discretion of the Company, the Company shall retain custody of the stock during the Restriction Period, (iii) the Holder may not sell, transfer, pledge, exchange, hypothecate or otherwise dispose of the stock during the Restriction Period and (iv) a breach of the terms and conditions established by the Committee pursuant to the Restricted Stock Award shall cause a forfeiture of the Restricted Stock Award. At the time of such Award, the Committee may, in its sole discretion, prescribe additional terms, conditions or restrictions relating to Restricted Stock Awards, including, but not limited to, rules pertaining to the termination of employment (by retirement, disability, death or otherwise) of a Holder prior to expiration of the Restriction Period. (c) PAYMENT FOR RESTRICTED STOCK. A Holder shall be required to make such payment for Common Stock received pursuant to a Restricted Stock Award as may be required by law or as the Committee may, in its discretion, determine to charge the Holder. (d) MISCELLANEOUS. Nothing in this Article shall prohibit the exchange of shares issued under the Plan (whether or not then subject to a Restricted Stock Award) pursuant to a plan of reorganization for stock or securities in the Company or another corporation a party to the reorganization, but the stock or securities so received for shares then subject to the restrictions of a Restricted Stock Award shall become subject to the restrictions of such Restricted Stock Award. Any shares of stock received as a result of a stock split or stock dividend with respect to shares then subject to a Restricted Stock Award shall also become subject to the restrictions of the Restricted Stock Award. X. PERFORMANCE SHARE AWARDS (a) PERFORMANCE PERIOD. The Committee shall establish, with respect to and at the time of each Performance Share Award, a performance period over which the performance applicable to the Performance Share Award of the Holder shall be measured. 26

(b) PERFORMANCE SHARE AWARDS. Each Performance Share Award may have a maximum value established by the Committee at the time of such Award. (c) PERFORMANCE MEASURES. A Performance Share Award may be awarded to an employee contingent upon future performance of the employee, the Company or any Subsidiary, division or department thereof by in which he is employed during the performance period, the Fair Market Value of Common Stock or the increase thereof during the performance period, combinations thereof, or such other provisions as the Committee may determine to be appropriate. The Committee shall establish the performance measures applicable to such performance prior to the beginning of the performance period but subject to such later revisions as the Committee shall deem appropriate to reflect significant, unforeseen events or changes. (d) AWARDS CRITERIA. In determining the value of Performance Share Awards, the Committee may take into account an employee's responsibility level, performance, potential, other Awards and such other considerations as it deems appropriate. (e) PAYMENT. Following the end of the performance period, the Holder of a Performance Share Award shall be entitled to receive payment of an amount, not exceeding the maximum value of the Performance Share Award, if any, based on the achievement of the performance measures for such performance period, as determined by the Committee in its sole discretion. Payment of a Performance Share Award (i) may be made in cash, Common Stock or a combination thereof, as determined by the Committee in its sole discretion, (ii) shall be made in a lump sum or in installments as prescribed by the Committee in its sole discretion and (iii) to the extent applicable, shall be based on the Fair Market Value of the Common Stock on the payment date. If a payment of cash is to be made on a deferred basis, the Committee shall establish whether interest shall be credited, the rate thereof and any other terms and conditions applicable thereto. (f) TERMINATION OF EMPLOYMENT. The Committee shall determine the effect of termination of employment during the performance period on an employee's Performance Share Award. XI. STOCK VALUE EQUIVALENT AWARDS (a) STOCK VALUE EQUIVALENT AWARDS. Stock Value Equivalent Awards are rights to receive an amount equal to the Fair Market Value of shares of Common Stock or rights to receive an amount equal to any appreciation or increase in the Fair Market Value of Common Stock over a specified period of time, which vest over a period of time as established by the Committee, without payment of any amounts by the Holder thereof (except to the extent otherwise required by law) or satisfaction of any performance criteria or objectives. Each Stock Value Equivalent Award may have a maximum value established by the Committee at the time of such Award. (b) AWARD PERIOD. The Committee shall establish, with respect to and at the time of each Stock Value Equivalent Award, a period over which the Award shall vest with respect to the Holder. 27

(c) AWARDS CRITERIA. In determining the value of Stock Value Equivalent Awards, the Committee may take into account an employee's responsibility level, performance, potential, other Awards and such other considerations as it deems appropriate. (d) PAYMENT. Following the end of the determined period for a Stock Value Equivalent Award, the Holder of a Stock Value Equivalent Award shall be entitled to receive payment of an amount, not exceeding the maximum value of the Stock Value Equivalent Award, if any, based on the then vested value of the Award. Payment of a Stock Value Equivalent Award (i) shall be made in cash, (ii) shall be made in a lump sum or in installments as prescribed by the Committee in its sole discretion and (iii) shall be based on the Fair Market Value of the Common Stock on the payment date. Cash dividend equivalents may be paid during, or may be accumulated and paid at the end of, the determined period with respect to a Stock Value Equivalent Award, as determined by the Committee. If payment of cash is to be made on a deferred basis, the Committee shall establish whether interest shall be credited, the rate thereof and any other terms and conditions applicable thereto. (e) TERMINATION OF EMPLOYMENT. The Committee shall determine the effect of termination of employment during the applicable vesting period on an employee's Stock Value Equivalent Award. XII. FINAL STOCK AWARDS (a) NATURE OF FINAL STOCK AWARDS. Final Stock Awards constitute the issuance as of January 17, 2001 to certain Holders of Restricted Stock Awards of one or more shares of Common Stock free and clear of any and all forfeiture restrictions or other encumbrances. (b) AUTOMATIC GRANT OF FINAL STOCK AWARDS. As of January 17, 2001, there shall be granted Final Stock Awards for a number of shares of Common Stock equal to the difference as of January 17, 2001 between 941,303 shares of Common Stock and the number of shares of Common Stock issued pursuant to Restricted Stock Awards granted under the Plan which have not been forfeited to the Company. Such shares of Common Stock shall be allocated to those individuals who (i) are employed by the Company or a Parent Corporation or a Subsidiary of the Company as of January 17, 2001 and (ii) who at any time were Holders of Restricted Stock Awards. An individual entitled to an allocation of a Final Stock Award pursuant to the preceding sentence shall receive a Final Stock Award for a number of shares of Common Stock equal to the total number of shares of Common Stock as to which Final Stock Awards are then being granted multiplied by a fraction, the numerator of which is the number of shares of Common Stock theretofore issued to him pursuant to his Restricted Stock Awards as to which forfeiture restrictions have lapsed and the denominator of which is the total number of shares of Common Stock theretofore issued pursuant to Restricted Stock Awards as to which forfeiture restrictions have lapsed to all individuals entitled to allocations of Final Stock Awards pursuant to the preceding sentence. XIII. RECAPITALIZATION OR REORGANIZATION (a) Except as hereinafter otherwise provided, Options, Stock Appreciation Rights, Restricted Stock Awards, Performance Share Awards, Stock Value Equivalent Awards and any agreements evidencing such Awards shall be subject to adjustment by the Committee at its 28

discretion as to the number and price of shares of Common Stock or other consideration subject to such Awards in the event of changes in the outstanding, Common Stock by reason of dividends payable in stock of the Company, stock splits, recapitalization, reorganizations, mergers, consolidations, combinations, exchanges or other relevant changes in capitalization occurring after the date of the grant of any such Option or Awards. (b) The existence of the Plan and the Awards granted hereunder shall not affect in any way the right or power of the Board or the stockholders of the Company to make or authorize any adjustment recapitalization, reorganization or other change in the Company's capital structure or its business, any merger or consolidation of the Company, any issue of debt or equity securities having any priority or preference with respect to or affecting Common Stock or the rights thereof, the dissolution or liquidation of the Company or any sale, lease, exchange or other disposition of all or any part of its assets or business or any other corporate act or proceeding. (c) The shares with respect to which Awards may be granted are shares of Common Stock as presently constituted, but if, and whenever, prior to the expiration of an Option theretofore granted, the Company shall effect a subdivision or consolidation of shares of Common Stock or the payment of a stock dividend on Common Stock payable in stock of the Company, without receipt of consideration by the Company, the number of shares of Common Stock with respect to which such Award may thereafter pertain (i) in the event of an increase in the number of outstanding shares shall be proportionately increased, and the purchase price per share shall be proportionately reduced, and (ii) in the event of a reduction in the number of outstanding shares shall be proportionately reduced, and the purchase price per share shall be proportionately increased. (d) If the Company recapitalizes or otherwise changes its capital structure, an Award theretofore granted shall be adjusted to reflect such recapitalization to the extent appropriate as determined by the Committee. XIV. AMENDMENT OR TERMINATION OF THE PLAN The Board in its discretion may terminate the Plan or alter or amend the Plan or any part thereof from time to time; provided that no change in any Award theretofore granted may be made which would impair the rights of the Holder without the consent of the Holder, and provided, further, that the Board may not, without approval of the stockholders amend the Plan: (a) to increase the aggregate number of shares of Common Stock which may be issued under the Plan, except as provided in Article XIII; (b) to change the class of employees eligible to receive Incentive Stock Options under the Plan; or (c) to modify materially the requirements as to eligibility for participation in the Plan if such approval is required by section 162(m) of the Code. 29

XV. OTHER (a) NO RIGHT TO AN AWARD. Neither the adoption of the Plan nor any action of the Board or of the Committee shall be deemed to give an employee any right to be granted an Option, a Stock Appreciation Right, a Restricted Stock Award or a Performance Share Award or Stock Value Equivalent Award, Final Stock Award or any other rights hereunder except as may be evidenced by an Option Agreement, Stock Appreciation Rights Agreement Restricted Stock Agreement or other instrument evidencing an Award duly executed on behalf of the Company, and then only to the extent and on the terms and conditions expressly set forth therein. The Plan shall be unfunded. The Company shall not be required to establish any special or separate fund or to make any other segregation of funds or assets to assure the payment of any Award. (b) NO EMPLOYMENT RIGHTS CONFERRED. Nothing contained in the Plan or in any Award made hereunder shall (i) confer upon any employee any right with respect to continuation of employment with the Company or any Subsidiary or (ii) interfere in any way with the right of the Company or any Subsidiary to terminate his or her employment at any time. (c) OTHER LAW; WITHHOLDING. The Company shall not be obligated to issue any Common Stock pursuant to any Award granted under the Plan at any time when the offering of the shares covered by such Award has not been registered under the Securities Act of 1933 and such other state and federal laws, rules or regulations as the Company or the Committee deems applicable and, in the opinion of legal counsel for the Company, there is no exemption from the registration requirements of such laws, rules or regulations available for the issuance and sale of such shares. No fractional shares of Common Stock shall be delivered, nor shall any cash in lieu of fractional shares be paid. The Company shall have the right to deduct in connection with all Awards any taxes required by law to be withheld and to require any payments necessary to enable it to satisfy its withholding obligations. The Committee may permit the Holder of an Award to elect to surrender, or authorize the Company to withhold, shares of Common Stock (valued at their Fair Market Value on the date of surrender or withholding of such shares) in satisfaction of the Company's withholding obligation. (d) NO RESTRICTION ON CORPORATE ACTION. Nothing contained in the Plan shall be construed to prevent the Company or any Subsidiary from taking any corporate action which is deemed by the Company or such Subsidiary to be appropriate or in its best interest, whether or not such action would have an adverse effect on the Plan or any Award made under the Plan. No employee, beneficiary or other person shall have any claim against the Company or any Subsidiary as a result of any such action. (e) RESTRICTIONS ON TRANSFER. An Award shall not be transferable otherwise than by will or the laws of descent and distribution and shall be exercisable during the lifetime of the Holder only by such Holder or the Holder's guardian or legal representative. The Option Agreement, Stock Appreciation Rights Agreement, Restricted Stock Agreement or other written instrument evidencing an Award shall specify the effect of the death of the Holder on the Award. (f) SEVERABILITY. If any provision of this Plan or an Award shall be held illegal or invalid for any reason, said illegality or invalidity shall not affect the remaining provisions thereof, 30

instead, each provision of the Plan or an Award shall be fully severable and shall be construed and enforced as if said illegal or invalid provision had never been included therein. (g) LIMITATION ON ACTIONS. Every right of action by or on behalf of the Company or by any stockholder against any past, present, or future member of the Board, the Committee, or any officer or employee of the Company arising out of or in connection with this Plan shall, regardless of the place where the action may be brought and regardless of the place of residence of any such director, Committee member, officer or employee, cease and be barred by the expiration of three years from the later of: (i) the date of the act or omission in respect of which such right of action arises or (ii) the first date upon which there has been made generally available to stockholders an annual report of the Company and a proxy statement for the annual meeting of stockholders following the issuance of such annual report, which annual report and proxy statement alone or together set forth for the related period, the amount of the allocations. In addition, any and all right of action by any employee (past, present or future) against the Company or any member of the Committee arising out of or in connection with this Plan will, regardless of the place where action may be brought and regardless of the place of residence of any Committee member, cease and be barred by the expiration of three years from the date of the act or omission in respect of which such right of action arises. (h) GOVERNING LAW. This Plan shall be governed by, and construed in accordance with, the internal laws of the State of Texas without regard to the principles of conflicts of law thereof that would require the application of the laws of any jurisdiction other than Texas, except to the extent that it implicates matters which are the subject of the General Corporation Law of the State of Delaware which matters shall be governed by the latter law. Executed as of the 15th day of May, 2002 to reflect the Third Amendment to that Plan document which was theretofore adopted by and executed on behalf of the Company.

Subject to the other provisions hereof, the U.S. Borrower may from time-to-time borrow, prepay (in whole or in part) and reborrow U.S. Swing Line Borrowings.

U.S. Administrative Agent shall give each U.S. Lender notice of such Mandatory U.S. Borrowing by 12:00 noon (Houston, Texas time) on the date the Mandatory U.S. Borrowing is to be made.

Upon receipt of such notice, such Administrative Agent shall promptly notify each U.S. Lender, Canadian Lender or Norwegian Lender, as the case may be, of the contents thereof and of such Lender's Commitment Percentage of the amount of such proposed Letter of Credit. No U.S. Letter of Credit may be issued if after giving effect thereto the sum of (A) the aggregate outstanding principal amount of U.S. Loans and U.S. Swing Line Loans plus (B) the aggregate 31

On each day during the period commencing with the issuance of any Letter of Credit and until such Letter of Credit shall have expired or been terminated, the U. S. Commitment, Canadian Commitment or Norwegian Commitment, as the case may be, of each applicable Lender shall be deemed to be utilized for all purposes hereof in an amount equal to such Lender's Commitment Percentage of the amount then available for drawings under such Letter of Credit (and any unreimbursed drawings under such Letter of Credit).

If at any time prior to the expiration date of a Letter of Credit any applicable Issuer shall have made a payment to a beneficiary of a Letter of Credit in respect of a drawing under such Letter of Credit, each applicable Lender will pay to the U.S. Administrative Agent, the Canadian Administrative Agent or Norwegian Administrative Agent, as the case may be, immediately upon demand by such Issuer at any time during the period commencing after such payment until reimbursement thereof in full by the applicable Borrower, an amount equal to such Lender's U.S. Commitment Percentage, Canadian Commitment Percentage or Norwegian Commitment Percentage, as the case may be, of such payment, together with interest on such amount for each day from the date of demand for such payment (or, if such demand is made after 11:00 a.m. Houston, Texas time (in the case of a U.S. Letter of Credit), 12:00 noon Calgary, Alberta time (in the case of a Canadian Letter of Credit) or 12:00 noon Oslo, Norway time (in the case of a Norwegian Letter of Credit) on such date, from the next succeeding Business Day) to the date of payment by such Lender of such amount at a rate of interest per annum equal to (i) in respect of U.S. Letters of Credit, the Federal Funds Rate, (ii) in respect of Canadian Letters of Credit which are denominated in Dollars, the Base Rate plus two percent (2%), (iii) in respect of Canadian Letters of Credit which are denominated in Canadian Dollars, the CDOR Rate, (iv) in respect of Norwegian Letters of Credit which are denominated in Dollars, the Base Rate plus two percent (2%) and (v) in respect of Norwegian Letters of Credit which are denominated in Norwegian Krone, the Eurokrone Rate plus two percent (2%). To the extent that it is ultimately determined that the applicable Borrower is relieved of its obligation to reimburse the applicable Issuer because of such Issuer's gross negligence or willful misconduct in determining that documents received under any applicable Letter of Credit comply with the terms thereof, the applicable Issuer shall be obligated to refund to the paying Lenders all amounts paid to such Issuer to reimburse Issuer for the applicable drawing under such Letter of Credit. U.S. Borrower, Canadian Borrowers or Norwegian Borrower, as the case may be, shall be irrevocably and unconditionally obligated forthwith to reimburse the appropriate Administrative Agent, on the date on which such Administrative Agent notifies U.S. Borrower, the applicable 32

Canadian Borrower or Norwegian Borrower, as the case may be, of the date and amount of any payment by the applicable Issuer of any drawing under a Letter of Credit, for the amount paid by such Issuer upon such drawing, without presentment, demand, protest or other formalities of any kind, all of which are hereby waived. Such reimbursement may, subject to satisfaction of the conditions in Sections 5.1 and 5.2 hereof and to the Maximum U.S. Available Amount, Maximum Canadian Available Amount or Maximum Norwegian Available Amount, as the case may be (after adjustment in the same to reflect the elimination of the corresponding Letter of Credit Liability), be made by the borrowing of Loans or, in the case of a Canadian Borrower, by the issuance, acceptance and purchase of Bankers' Acceptances. The applicable Administrative Agent will pay to each Lender such Lender's Commitment Percentage of all amounts received from U.S. Borrower, Canadian Borrowers or Norwegian Borrower, as the case may be, for application in payment, in whole or in part, of the Reimbursement Obligation in respect of any Letter of Credit, but only to the extent such Lender has made payment to the applicable Administrative Agent in respect of such Letter of Credit pursuant to clause (iii) above. Each Borrower hereby unconditionally and irrevocably authorizes, empowers, and directs the applicable Administrative Agent and the Lenders to record and otherwise treat each payment under a Letter of Credit issued for the account of such Borrower not reimbursed when due hereunder as a Base Rate Borrowing to such Borrower. The issuance by the applicable Issuer of each Letter of Credit shall, in addition to the conditions precedent set forth in Article V hereof, be subject to the conditions precedent (A) that such Letter of Credit shall be in such form and contain such terms as shall be reasonably satisfactory to applicable Administrative Agent, and (B) that U.S. Borrower, Canadian Borrowers or Norwegian Borrower, as the case may be, shall have executed and delivered such Applications and other instruments and agreements relating to such Letter of Credit as the applicable Administrative Agent shall have reasonably requested and are not inconsistent with the terms of this Agreement. In the event of a conflict between the terms of this Agreement and the terms of any Application, the terms hereof shall control. Each Issuer will send to U.S. Borrower, the applicable Canadian Borrower or Norwegian Borrower, as the case may be, and each applicable Lender, immediately upon issuance of any Letter of Credit issued by such Issuer or any amendment thereto, a true and correct copy of such Letter of Credit or amendment.

In the event any Letter of Credit is drawn, that portion of the applicable letter of credit fee provided for in the preceding sentence relating to the period beyond the date of such drawing shall be credited to the applicable Borrower's Reimbursement Obligations relating thereto. The applicable Administrative Agent will pay to each applicable Lender, promptly after receiving any payment in respect of letter of credit fees referred to in this clause (2), an amount equal to the product of such Lender's U.S. Commitment Percentage, Canadian Commitment Percentage or Norwegian Commitment Percentage, as the case may be, times the amount of such fees; and U.S. Borrower, the applicable Canadian Borrower or Norwegian Borrower, as the case may be, shall pay to the applicable Issuing Bank, on demand, such other fronting, amendment, transfer, negotiation and other fees as determined in accordance with the applicable Issuing Bank's then current fee policy regarding Commercial Letters of Credit; The applicable Issuing Bank shall neither renew or extend nor permit the renewal or extension of any Commercial Letter of Credit if after giving effect to such renewal, the expiry date of such Commercial Letter of Credit would be a date that is later than the Maturity Date. For each Standby Letter of Credit issued on behalf of each Borrower: U.S. Borrower, the applicable Canadian Borrower or Norwegian Borrower, as the case may be, will pay to the appropriate Administrative Agent at the Principal Office of such Administrative Agent for the account of each applicable Lender a letter of credit fee with respect to each Standby Letter of Credit equal to the Margin Percentage applicable to LIBOR Borrowings or NIBOR Borrowings, as the case may be, multiplied by the face amount available of each Standby Letter of Credit issued (and computed on the basis of the actual number of days elapsed in a year composed of 360 days), in each case for the period from and including the date of issuance of such Letter of Credit to and including the date of expiration or termination thereof, such fee to be due and payable quarterly (i) in arrears in the case of U.S. Letters of Credit and Norwegian Letters of Credit and (ii) in case of Canadian Letters of Credit in advance. After the occurrence of an Event of Default which has not been cured or waived, the letter of credit fee provided for the preceding sentence shall, on a Tranche-by-Tranche basis, be increased by two percent (2%) per annum upon the approval of such increase by Lenders having 50% or more of the Aggregate Commitments related to such Tranche, such increased fee to be due and payable upon demand by the applicable Administrative Agent. In the event any Letter of Credit is drawn, that portion of the applicable letter of credit fee provided for in the preceding sentence relating to the period beyond the date of such drawing shall be credited to the applicable Borrower's Reimbursement Obligations relating thereto.

INDEMNIFICATION; RELEASE. Each of U.S. Borrower, Canadian Borrowers and Norwegian Borrower, as the case may be, hereby indemnifies and holds harmless each applicable Administrative Agent, each applicable Lender and each applicable Issuer from and against any and all claims and damages, losses, liabilities, costs or expenses which such Administrative Agent, such Lender or such Issuer may incur (or which may be claimed against such Administrative Agent, such Lender or such Issuer by any Person whatsoever), REGARDLESS OF WHETHER CAUSED IN WHOLE OR IN PART BY THE NEGLIGENCE OF ANY OF THE INDEMNIFIED PARTIES, in connection with the execution and delivery of any Letter of Credit or transfer of or payment or failure to pay under any Letter of Credit; provided that U.S. Borrower, Canadian Borrowers or Norwegian Borrower, as the case may be, shall not be required to indemnify any party seeking indemnification for any claims, damages, losses, liabilities, costs or expenses to the extent, but only to the extent, caused by (i) the willful misconduct or gross negligence of the party seeking indemnification, or (ii) the failure by the party seeking indemnification to pay under any Letter of Credit after the presentation to it of a request required to be paid under applicable law. U.S. Borrower, Canadian Borrowers or Norwegian Borrower, as the case may be, hereby releases, waives and discharges each Administrative Agent, each Lender and each Issuer from any claims, causes of action, damages, losses, liabilities, reasonable costs or expenses which may now exist or may hereafter arise, REGARDLESS OF WHETHER CAUSED IN WHOLE OR IN PART BY THE NEGLIGENCE OF ANY OF THE INDEMNIFIED connection with the failure of any other Lender to fulfill or comply with its obligations to such Administrative Agent, such Lender or such Issuer, as the case may be, hereunder (but nothing herein contained shall affect any rights U.S. Borrower, Canadian Borrowers or Norwegian Borrower, as the case may be, may have against such defaulting Lender or may have in respect of gross negligence or willful misconduct). Nothing in this Section 2.3(d) is intended to limit the obligations of U.S. Borrower, Canadian Borrowers or Norwegian Borrower, as the case may be, under any other provision of this Agreement. ADDITIONAL COSTS IN RESPECT OF LETTERS OF CREDIT. If as a result of any Regulatory Change there shall be imposed, modified or deemed applicable any tax (other than any franchise tax or tax based on or measured by income or revenues), reserve, special deposit or similar requirement against or with respect to or measured by reference to Letters of Credit issued or to be issued hereunder or participations in such Letters of Credit, and the result shall be to increase the cost to any Lender of issuing or maintaining any Letter of Credit or any participation therein, or materially reduce any amount receivable by any Lender hereunder 35

in respect of any Letter of Credit or any participation therein (which increase in cost, or reduction in amount receivable, shall be the result of such Lender's reasonable allocation of the aggregate of such increases or reductions resulting from such event), then such Lender shall notify U.S. Borrower, the applicable Canadian Borrower or Norwegian Borrower, as the case may be, through the appropriate Administrative Agent (which notice shall be accompanied by a statement setting forth in reasonable detail the basis for the determination of the amount due), and within 15 Business Days after demand therefor by such Lender through such Administrative Agent, U.S. Borrower, the applicable Canadian Borrower or Norwegian Borrower, as the case may be, shall pay to such Lender, from time to time as specified by such Lender, such additional amounts as shall be sufficient to compensate such Lender for such increased costs or reductions in amount. Such statement as to such increased costs or reductions in amount incurred by such Lender, submitted by such Lender to U.S. Borrower, the applicable Canadian Borrower or Norwegian Borrower, as the case may be, shall be conclusive as to the amount thereof, absent manifest error, and may be computed using any reasonable averaging and attribution method. Each Lender will notify U.S. Borrower, the applicable Canadian Borrower or Norwegian Borrower, as the case may be, through the appropriate Administrative Agent of any event occurring after the date of this Agreement which will entitle such Lender to compensation pursuant to this Section as promptly as practicable after any executive officer of such Lender obtains knowledge thereof and determines to request such compensation, and (if so requested by U.S. Borrower, the applicable Canadian Borrower or Norwegian Borrower, as the case may be, through the appropriate Administrative Agent) will designate a different lending office of such Lender for the issuance or maintenance of Letters of Credit by such Lender or will take such other action as U.S. Borrower, the applicable Canadian Borrower or Norwegian Borrower, as the case may be, may reasonably request if such designation or action is consistent with the internal policy of such Lender and legal and regulatory restrictions, can be undertaken at no additional cost, will avoid the need for, or reduce the amount of, such compensation and will not, in the sole opinion of such Lender, be disadvantageous to such Lender (provided that no such U.S. Lender shall have any obligation so to designate a different lending office which is not located in the United States of America, no such Canadian Lender shall have any obligation so to designate a different lending office which is not located in Canada and no such Norwegian Lender shall have any obligation so to designate a different lending office which is not located in Norway). COLLATERAL ACCOUNT. U.S. Borrower, Canadian Borrowers or Norwegian Borrower, as the case may be, shall be required to deposit cash or an irrevocable standby letter of credit issued by a bank or other financial institution acceptable to the Issuing Bank (such acceptance not to be unreasonably withheld), for the benefit of the U.S. Lender, Canadian Lender or Norwegian Lender, as the case may be, in an account of the Issuing Bank if (i) required pursuant to any Section herein, or (ii) within 30 days prior to the Maturity Date then in effect in an amount equal to the Letter of Credit Exposure as of such date. EXISTING LETTERS OF CREDIT. On the date of this Agreement, the Existing Canadian Letters of Credit will become Canadian Letters of Credit hereunder and the Existing Norwegian Letters of Credit will become Norwegian Letters of Credit hereunder and all provisions of this Section 2.3 and this Agreement shall apply to the Existing Canadian Letters of Credit 36

and Existing Norwegian Letters of Credit as if they had been issued hereunder. On the date of this Agreement, the Issuing Bank shall issue a Standby Letter of Credit to cover or back the full outstanding and undrawn amount of the Existing U.S. Letters of Credit. This Standby Letter of Credit will become a U.S. Letter of Credit hereunder and all provisions of this Section 2.3 and this Agreement shall apply thereto. CERTAIN PROVISIONS RELATING TO BANKERS' ACCEPTANCES. Subject to the terms and conditions hereof, each Canadian Lender severally agrees to accept and purchase Bankers' Acceptances drawn upon it by either Canadian Borrower denominated in Canadian Dollars. The applicable Canadian Borrower shall notify the Canadian Administrative Agent by irrevocable written notice (each a "Bankers' Acceptance Notice") by 12:00 noon (Calgary, Alberta time) two (2) Business Days prior to the proposed date of any borrowing by way of Bankers' Acceptances. Each borrowing by way of Bankers' Acceptances shall be in a minimum aggregate face amount of C$1,000,000 and integral multiples of C$100,000 in excess thereof. The face amount of each Bankers' Acceptance shall be C$100,000 or any integral multiple thereof. Each Bankers' Acceptance Notice shall be in the form of Exhibit I. Bankers' Acceptances shall be issued and shall mature on a Business Day. Each Bankers' Acceptance shall have a term of 30, 60, 90 or, if available, 180 days excluding days of grace and shall mature on or before the Maturity Date and shall be in form and substance reasonably satisfactory to the Canadian Administrative Agent. To facilitate the acceptance of Bankers' Acceptances under this Agreement, each Canadian Borrower shall, upon execution of this Agreement and from time to time as required, provide to the Canadian Administrative Agent drafts, in form satisfactory to the Canadian Administrative Agent, duly executed and endorsed in blank by such Canadian Borrower in quantities sufficient for each Canadian Lender to fulfill its obligations hereunder. Each Canadian Borrower recognizes and agrees that all Bankers' Acceptances signed and/or endorsed on its behalf by a Canadian Lender shall bind such Canadian Borrower as fully and effectually as if signed in the handwriting of and duly issued by the proper signing officer of such Canadian Borrower. Each Canadian Lender is hereby authorized to issue such Bankers' Acceptances endorsed in blank in such face amounts as may be determined by such Canadian Lender provided that the aggregate amount thereof is equal to the aggregate amount of Bankers' Acceptances required to be accepted by such Canadian Lender. No Canadian Lender shall be responsible or liable for its failure to accept a Bankers' Acceptance if the cause of such failure is, in whole or in part, due to the failure of the respective Canadian Borrower to provide duly executed and endorsed drafts to the Canadian Administrative Agent on a timely basis nor shall any Canadian Lender be liable for any damage, loss or other claim arising by reason of any loss or improper use of any such instrument except loss or improper use arising by reason of the gross negligence or willful misconduct of such Canadian Lender, its officers, employees, Administrative Agents or representatives. Each Canadian Lender shall maintain a record with respect to Bankers' Acceptances (i) received by it from the Canadian Administrative Agent or either Canadian Borrower in blank hereunder, (ii) voided by it for any reason, (iii) accepted by it hereunder, (iv) purchased by it hereunder and (v) canceled at their respective maturities. Each Canadian Lender further agrees to retain such records in the manner and for the statutory periods provided in the various Canadian provincial or federal statutes and regulations which apply to such Canadian Lender. 37

Subject to Section 2.4(d) below, drafts of each Canadian Borrower to be accepted as Bankers' Acceptances hereunder shall be duly executed by a duly authorized officer of such Canadian Borrower. Notwithstanding that any person whose signature appears on any Bankers' Acceptance as a signatory for each Canadian Borrower may no longer be an authorized signatory for such Canadian Borrower at the date of issuance of a Bankers' Acceptance, such signature shall nevertheless be valid and sufficient for all purposes as if such authority had remained in force at the time of such issuance and any such Bankers' Acceptance so signed shall be binding on such Canadian Borrower. Promptly following receipt of a Bankers' Acceptance Notice, the Canadian Administrative Agent shall so advise the Canadian Lenders and shall advise each Canadian Lender of the face amount of each Bankers' Acceptance to be accepted by it and the term thereof. The aggregate face amount of Bankers' Acceptances to be accepted by a Canadian Lender shall be determined by the Canadian Administrative Agent by reference to the respective Canadian Commitments of the Canadian Lenders, except that, if the face amount of a Bankers' Acceptance, which would otherwise be accepted by a Canadian Lender, would not be C$100,000 or an integral multiple thereof, such face amount shall be increased or reduced by the Canadian Administrative Agent in its sole and unfettered discretion to the nearest integral multiple of C$100,000. Each Bankers' Acceptance to be accepted by a Canadian Lender shall be accepted at such Canadian Lender's office shown on the signature pages hereof or as otherwise designated by such Canadian Lender from time to time. On the relevant borrowing date, each Canadian Lender severally agrees to purchase from the applicable Canadian Borrower, at the face amount thereof discounted by the Applicable BA Discount Rate, any Bankers' Acceptance accepted by it and provided to the Canadian Administrative Agent, for the account of such Canadian Borrower, the BA Discount Proceeds in respect thereof after deducting therefrom the amount of the Acceptance Fee payable by such Canadian Borrower to such Canadian Lender and the Canadian Administrative Agent under Section 2.4(c) in respect of such Bankers' Acceptance. Each Canadian Lender may at any time and from time to time hold, sell, rediscount or otherwise dispose of any or all Bankers' Acceptances accepted and purchased by it. Each Canadian Borrower waives presentment for payment and any other defense to payment of any amounts due to a Canadian Lender in respect of a Bankers' Acceptance accepted by it pursuant to this Agreement which might exist solely by reason of such Bankers' Acceptance being held, at the maturity thereof, by such Canadian Lender in its own right and each Canadian Borrower agrees not to claim any days of grace if such Canadian Lender as holder sues such Canadian Borrower on the Bankers' Acceptances for payment of the amount payable by such Canadian Borrower thereunder. With respect to each Bankers' Acceptance, a Canadian Borrower, prior to the occurrence and continuation of a Default, may give irrevocable telephone or written notice (or such other method of notification as may be agreed upon between the Canadian Administrative Agent and such Canadian Borrower) to the Canadian Administrative Agent at or before 12:00 noon (Calgary, Alberta time) two (2) Business Days prior to the maturity date of such Bankers' Acceptance followed by written confirmation electronically transmitted to the Canadian 38

Administrative Agent on the same day, of such Canadian Borrower's intention to issue one or more Bankers' Acceptance on such maturity date (each a "Refunding Bankers' Acceptance") to provide for the payment of such maturing Bankers' Acceptance (it being understood that payments by such Canadian Borrower and fundings by the Canadian Lenders in respect of each maturing Bankers' Acceptance and each related Refunding Bankers' Acceptance shall be made on a net basis reflecting the difference between the face amount of such maturing Bankers' Acceptance and the BA Discount Proceeds (net of the applicable Acceptance Fee) of such Refunding Bankers' Acceptance). Any funding on account of any maturing Bankers' Acceptance must be made at or before 12:00 noon (Calgary, Alberta time) on the maturity date of such Bankers' Acceptance. If such Canadian Borrower fails to give such notice, then subject to satisfaction of the conditions in Section 5 hereof and to the Maximum Canadian Available Amount, such Canadian Borrower shall be irrevocably deemed to have requested and to have been advanced a Canadian Prime Loan in the face amount of such maturing Bankers' Acceptance on the maturity date of such Bankers' Acceptance from the Canadian Lender which accepted such maturing Bankers' Acceptance, which Canadian Prime Loan shall thereafter bear interest as such in accordance with the provisions hereof until paid in full. An Acceptance Fee shall be payable by the applicable Canadian Borrower to each Canadian Lender in advance (in the manner specified in Section 2.4(a)(6)) in respect of, and as a condition precedent to the acceptance by such Canadian Lender of, a Bankers' Acceptance to be accepted by such Canadian Lender calculated at the rate per annum equal to the Margin Percentage applicable to LIBOR Borrowings, calculated on the face amount of such Bankers' Acceptance and computed on the basis of the number of days in the term of such Bankers' Acceptance and a year of 365 days. DEPOSITORY BILLS AND NOTES ACT. If and for so long as the power of attorney referred to in subsection 2.4(e) is in force with respect to each of the Canadian Lenders, it is intended that pursuant to the DBNA, all Bankers' Acceptances accepted by the Canadian Lenders under this Agreement will be issued in the form of a "depository bill" (as defined in the DBNA), deposited with a "clearing house" (as defined in the DBNA, including, without limitation, The Canadian Depository for Securities Ltd. or its nominee CDS & Co.). In order to give effect to the foregoing, the Canadian Agent will, subject to the approval of Canadian Borrowers, establish and notify Canadian Borrowers and the Canadian Lenders of any additional procedures, consistent with the terms of this Agreement and the DBNA, as are reasonably necessary to accomplish such intention, including: any instrument held by the Canadian Agent for the purposes of Bankers' Acceptances will have marked prominently and legibly on its face and within its text, at or before the time of issue, the words "This is a depository bill subject to the Depository Bills and Notes Act (Canada)"; any reference to the authentication of the Bankers' Acceptance will be removed; and any reference to the "bearer" will be removed and such Bankers' Acceptances will not be marked with any words prohibiting negotiation, transfer or assignment of it or of an interest in it. 39

POWER OF ATTORNEY. Canadian Borrowers hereby appoint the Canadian Agent and each Canadian Lender, acting by any authorized signatory of any such Person, the attorney of the undersigned: to execute, for and on behalf and in the name of the applicable Canadian Borrower as drawer of, and to endorse on its behalf, drafts in such Person's standard form which constitute depository bills for the purpose of the DBNA; to complete the amount, date and maturity date of such Bankers' Acceptances; and to deposit such Bankers' Acceptances which have been accepted by such Person with a clearing house (as defined in the DBNA); provided that such acts in each case are to be undertaken by such Person strictly in accordance with instructions given to it by the applicable Canadian Borrower as provided in this subsection 2.4(e). For certainty, signatures of any authorized signatory of such Person may be mechanically reproduced in facsimile on Bankers' Acceptances (or Discount Notes as applicable) issued in accordance with this Agreement and such facsimile signatures will be binding and effective as if they had been manually executed by such authorized signatory of such Person. Instructions from the applicable Canadian Borrower to such Person relating to the execution, completion, endorsement, discount and/or delivery by such Person on behalf of the applicable Canadian Borrower of Bankers' Acceptances will be communicated by delivery to the Canadian Agent of a Request for Extension of Credit (Canadian Borrowers) or a Rate Designation Notice, as applicable. This power of attorney may be withdrawn by Canadian Borrowers by providing the Canadian Agent and each Canadian Lender with 2 days written notice of such withdrawal. TERMINATIONS, REDUCTIONS OR REALLOCATIONS OF COMMITMENTS. MANDATORY. On the Termination Date, all Commitments shall be terminated in their entirety. OPTIONAL. U.S. Borrower, either Canadian Borrower or Norwegian Borrower, as the case may be, shall have the right to terminate or reduce the unused portion of the U.S. Commitments, Canadian Commitments or Norwegian Commitments, as the case may be, at any time or from time to time, provided that (i) U.S. Borrower, either Canadian Borrower or Norwegian Borrower, as the case may be, shall give notice of each such termination or reduction to the appropriate Administrative Agent as provided in Section 4.3 hereof and (ii) each such partial reduction shall be in an integral multiple of US$5,000,000. Notwithstanding the foregoing, U.S. Borrower may not reduce the U.S. Commitments below the then outstanding principal balance of the U.S. Obligations, Canadian Borrowers may not reduce the Canadian Commitments below the then outstanding principal balance of the Canadian Obligations, and Norwegian Borrower may not reduce the Norwegian Commitments below the then outstanding principal balance of the Norwegian Obligations. No termination or reduction of the Commitments pursuant to this provision may be reinstated without the prior written approval of Administrative Agents and the Lenders. REALLOCATIONS. Any Multiple Lender may agree with Borrowers to reallocate its existing U.S. Commitment, Canadian Commitment or Norwegian Commitment, so long as the sum of such U.S. Commitment, Canadian Commitment and Norwegian Commitment remains unchanged. 40

In addition, with the prior written consent of all of the Multiple Lenders, any U.S. Lender may agree with Borrowers to convert a portion of its U.S. Commitment into a Canadian Commitment or Norwegian Commitment, thereby becoming a Multiple Lender, and any Canadian Lender may agree with Borrowers to convert a portion of its Canadian Commitment into a U.S. Commitment or Norwegian Commitment, thereby becoming a Multiple Lender, and any Norwegian Lender may agree with Borrowers to convert a portion of its Norwegian Commitment into a Canadian Commitment or U.S. Commitment, thereby becoming a Multiple Lender, in each case so long as (i) each Lender continues to be a U.S. Lender with a U.S. Commitment of at least US$1,000,000, (ii) the sum of such Lender's U.S. Commitment, Canadian Commitment and Norwegian Commitment remains equal to the aggregate amount of such Lender's U.S. Commitment, Canadian Commitment and Norwegian Commitment, as the case may be, prior to such reallocation and (iii) the Canadian Commitment and Norwegian Commitment, each individually, shall not exceed US$40,000,000. Borrowers shall give written notice to the Administrative Agents of any reallocation pursuant to this provision at least ten (10) Business Days prior to the effective date of any such reallocation. No applicable Lender affected by such reallocation shall be required to agree to any such reallocation, but may do so at its option, in its sole discretion. The following conditions precedent must be satisfied prior to any such reallocation becoming effective: no Default or Event of Default shall have occurred and be continuing; if, as a result of any such reallocation, the aggregate U.S. Obligations would exceed the aggregate of all of the U.S. Commitments, then the U.S. Borrower shall, on the effective date of such reallocation, repay or prepay U.S. Loans (or provide Cover for Letter of Credit Liabilities relating to U.S. Letters of Credit) in accordance with this Agreement in an aggregate principal amount such that, after giving effect thereto, the aggregate U.S. Obligations shall not exceed the aggregate of all of the U.S. Commitments; if, as a result of any such reallocation, the Total Canadian Exposure would exceed the aggregate of all of the Canadian Commitments, then Canadian Borrowers shall, on the effective date of such reallocation, repay or prepay Canadian Loans(or provide Cover for Letter of Credit Liabilities relating to Canadian Letters of Credit or for Bankers' Acceptance Liabilities) in accordance with this Agreement in an aggregate principal amount such that, after giving effect thereto, the Total Canadian Exposure shall not exceed the aggregate of all of the Canadian Commitments; if, as a result of any such reallocation, the Total Norwegian Exposure would exceed the aggregate of all of the Norwegian Commitments, then Norwegian Borrower shall, on the effective date of such reallocation, repay or prepay Norwegian Loans (or provide Cover for Letter of Credit Liabilities relating to Norwegian Letters of Credit) in accordance with this Agreement in an aggregate principal amount such that, after giving effect thereto, the Total Norwegian Exposure shall not exceed the aggregate of all of the Norwegian Commitments; Borrowers shall have paid any amounts (or shall have provided Cover) due under Sections 2.11(c) or (d) or Section 2.11(e) hereof on the date of such reallocation; The Maximum U.S. Available Amount shall be adjusted to equal the sum of all of the U.S. Commitments after giving effect to such reallocation, the Maximum Canadian Available Amount shall be adjusted to equal the sum of all of the Canadian Commitments after giving effect to such 41

reallocation and the Maximum Norwegian Available Amount shall be adjusted to equal the sum of all of the Norwegian Commitments after giving effect to such reallocation; Participations by the Lenders in the outstanding Letters of Credit and the Letter of Credit Liabilities and the outstanding Loans of the Lenders shall be adjusted to give effect to such reallocation; provided, however, that in lieu of requiring any prepayment of any Bankers' Acceptances in order to make appropriate adjustments to give effect to such reallocations, Canadian Borrowers shall be required to provide additional Cover for any applicable portion of the Bankers' Acceptance Liabilities; each Lender whose U.S. Commitment, Canadian Commitment or Norwegian Commitment, as the case may be, shall be the subject of any reallocation shall have received from the Borrowers a fee equal to the greater of the applicable equivalent of US$10,000 or 1/16% of the amount of the increase or decrease, as the case may be, in its respective U.S. Commitment, Canadian Commitment or Norwegian Commitment. UTILIZATION FEES. UTILIZATION FEES. U.S. Borrower, Canadian Borrowers or Norwegian Borrower, as the case may be, agrees to pay to the U.S. Administrative Agent, for the ratable benefit of the Lenders, a daily utilization fee per annum equal to the Margin Percentage in effect from time to time, times the Total Outstandings on each day that the Total Outstandings exceed 33 1/3% of the total of the Aggregate Commitments (or if the Aggregate Commitments have terminated, on the Total Outstandings), from the Effective Date until the later of the Termination Date or repayment in full of the Obligations, such fees due and payable quarterly in arrears on the twentieth calendar day (or the first day thereafter that is a Business Day) after the last Business Day of each March, June, September and December, commencing October 21, 2002, and on the Termination Date. The Utilization Fee shall accrue at all times so long as any of the U.S. Commitment, Canadian Commitment or Norwegian Commitment or any of the Obligations remain outstanding, including at any time during which one or more of the conditions in Article V is not met. If there is any change in the Margin Percentage during any quarter, the actual daily amount shall be computed and multiplied by the Margin Percentage separately for each period during such quarter that such Margin Percentage was in effect. For purposes of computation of the above fees, within 10 days of the quarter then ended, Canadian Agent and Norwegian Agent shall deliver to the U.S. Agent a daily log of outstanding amounts in Dollars under the Canadian Commitment and Norwegian Commitment, as the case may be, for the preceding quarter. All past due fees payable under this Section shall bear interest at the Default Rate. FACILITY FEES. U.S. Borrower, Canadian Borrowers or Norwegian Borrower, as the case may be, agrees to pay to the U.S. Administrative Agent, the Canadian Administrative Agent or the Norwegian Administrative Agent, as the case may be, for the benefit of the U.S. Lender, Canadian Lender or Norwegian Lender, as the case may be, a daily Facility Fee per annum equal to the Margin Percentage in effect on the date such payment is due from time to time, times the actual daily amount of the respective U.S. Commitment, Canadian Commitment, or 42

Norwegian Commitment, as the case may be, regardless of usage (or if the Aggregate Commitments have terminated on the Total Outstandings), from the Effective Date until the later of the Termination Date or repayment in full of the Obligations, such fees due and payable quarterly in arrears on the twentieth calendar day (or the first day thereafter that is a Business Day) after the last Business Day of each March, June, September and December, commencing October 21, 2002, and on the Termination Date. The Facility Fee shall accrue at all times so long as any of the U.S. Commitment, Canadian Commitment or Norwegian Commitments or any of the Obligations remain outstanding, including at any time during which one or more of the conditions in Article V is not met. If there is any change in the Margin Percentage during any quarter, the actual daily amount shall be computed and multiplied by the Margin Percentage separately for each period during such quarter that such Margin Percentage was in effect. All past due fees payable under this Section shall bear interest at the Default Rate. SEVERAL OBLIGATIONS. The failure of any Lender to make any Loan to be made by it or to accept and purchase any Bankers' Acceptance required to be so accepted and purchased by it on the date specified therefor shall not relieve any other Lender of its obligation to make its Loan or to accept and purchase its Bankers' Acceptance on such date, but neither any Administrative Agent nor any Lender shall be responsible or liable for the failure of any other Lender to make a Loan or to accept and purchase any Bankers' Acceptance or to participate in, or co-issue, any Letter of Credit. Notwithstanding anything contained herein to the contrary, (i) if a U.S. Lender fails to make a U.S. Loan as and when required hereunder, then upon each subsequent event which would otherwise result in payments of principal being made to the defaulting U.S. Lender, the amount which would have been paid to the defaulting U.S. Lender shall be divided among the non-defaulting U.S. Lenders ratably according to their respective Commitment Percentages until the Obligations of each U.S. Lender (including the defaulting U.S. Lender) are equal to such U.S. Lender's Commitment Percentage of the total U.S. Obligations, (ii) if a Canadian Lender fails to make a Canadian Loan or accept and purchase any Bankers' Acceptance as and when required hereunder, then upon each subsequent event which would otherwise result in payments of principal being made to the defaulting Canadian Lender, the amount which would have been paid to the defaulting Canadian Lender shall be divided among the non-defaulting Canadian Lenders ratably according to their respective Commitment Percentages until the Obligations of each Canadian Lender (including the defaulting Canadian Lender) are equal to such Canadian Lender's Commitment Percentage of the total Canadian Obligations, and (iii) if a Norwegian Lender fails to make a Norwegian Loan as and when required hereunder, then upon each subsequent event which would otherwise result in payments of principal being made to the defaulting Norwegian Lender, the amount which would have been paid to the defaulting Norwegian Lender shall be divided among the non-defaulting Norwegian Lenders ratably according to their respective Commitment Percentages until the Obligations of each Norwegian Lender (including the defaulting Norwegian Lender) are equal to such Norwegian Lender's Commitment Percentage of the total Norwegian Obligations. In each case, no Default or Event of Default shall exist or result from any defaulting Lender not receiving payment when due as a result of this Section 2.8. EVIDENCE OF DEBT. 43

The U.S. Loans made by each U.S. Lender shall be evidenced by a U.S. Note of U.S. Borrower in substantially the form of Exhibit D hereto payable to the order of such U.S. Lender in a principal amount equal to the U.S. Commitment of such U.S. Lender, and otherwise duly completed and a U.S. Swing Line Note of U.S. Borrower in substantially the form of Exhibit F hereto payable to the order of such U.S. Swing Line Lender in a principal amount equal to the Commitment of such U.S. Swing Line Lender, and otherwise duly completed.. The Canadian Loans made by each Canadian Lender which are denominated in Dollars shall be evidenced by a single Canadian Note of Canadian Borrowers in substantially the form of Exhibit C hereto payable to the order of such Canadian Lender in a principal amount equal to the Canadian Commitment of such Canadian Lender, and otherwise duly completed. The Canadian Prime Loans made by each Canadian Lender shall be evidenced by a single Canadian Dollar Note of Canadian Borrowers in substantially the form of Exhibit J hereto payable to the order of such Canadian Lender in a principal amount equal to US$20,000,000. The Norwegian Loans made by each Norwegian Lender which are denominated in Dollars shall be evidenced by a single Norwegian Krone Note of Norwegian Borrower in substantially the form of Exhibit E hereto payable to the order of such Norwegian Lender in a principal amount equal to the Norwegian Commitment of such Norwegian Lender, and otherwise duly completed. The Norwegian Loans made by each Norwegian Lender shall be evidenced by a single Norwegian Krone Note of Norwegian Borrower in substantially the form of Exhibit L hereto payable to the order of such Norwegian Lender in a principal amount equal to US$20,000,000, and otherwise duly completed. The promissory notes described in this Section are each, together with all renewals, extensions, modifications and replacements thereof and substitutions therefor, called a "Note" and collectively called the "Notes". Each Lender is hereby authorized by each Borrower to endorse on the schedule (or a continuation thereof) that may be attached to each Note of such Lender, to the extent applicable, the date, amount, type of and the applicable period of interest for each Loan made by such Lender to the applicable Borrower hereunder, and the amount of each payment or prepayment of principal of such Loan received by such Lender, provided, that any failure by such Lender to make any such endorsement shall not affect the obligations of any Borrower under such Note or hereunder in respect of such Loan. In addition to Notes, the Loans made by each Lender shall be evidenced by one or more accounts or records maintained by such Lender and by the applicable Administrative Agent in the ordinary course of business. The accounts or records maintained by the applicable Administrative Agent and each Lender shall be conclusive absent manifest error of the amount of the Loans made by the Lenders to the Borrowers and the interest and payments thereon. In the event of conflict between the Notes and such accounts and records, such accounts and records shall control. Any failure to so record or any error in doing so shall not, however, limit or otherwise affect the obligation of the Borrowers hereunder to pay any amount owing with respect to the Obligations. In the event of any conflict between the accounts and records maintained by any Lender and the accounts and records of the applicable Administrative Agent in respect of such matters, the accounts and records of the applicable Administrative Agent shall control in the absence of manifest error. In addition to the accounts and records referred to in subsection (b), each Lender and the applicable Administrative Agent shall maintain in accordance with its usual practice 44

accounts or records evidencing the purchases and sales by such Lender of participations in U.S. Letters of Credit, Canadian Letters of Credit or Norwegian Letters of Credit, as the case may be, Bankers' Acceptances and U.S. Swing Line Loans. In the event of any conflict between the accounts and records maintained by the applicable Administrative Agent and the accounts and records of any Lender in respect of such matters, the accounts and records of the applicable Administrative Agent shall control in the absence of manifest error. USE OF PROCEEDS. The proceeds of the Loans and of the acceptance and purchase of Bankers' Acceptances may be used by the Borrowers for any lawful corporate purpose not expressly prohibited in this Agreement including, without limitation, (i) to refinance certain existing indebtedness of the Borrowers, and (ii) other working capital and general corporate purposes of the Parent, Borrowers and their respective Subsidiaries. Neither any Administrative Agent nor any Lender shall have any responsibility as to the use of any proceeds of the Loans or of the acceptance and purchase of Bankers' Acceptances. No Borrower will, nor will it permit any Subsidiary to, use any of the proceeds of the U.S. Borrowings, Canadian Borrowings and Norwegian Borrowings to purchase or carry any "margin stock" (as defined in Regulation U of the Board of Governors of the Federal Reserve System) that would cause any Lender to be in violation of Regulation U or any Borrower to be in violation of Regulation X of the Board of Governors of the Federal Reserve System. CURRENCY FLUCTUATIONS. Not later than (i) 1:00 p.m. (Calgary, Alberta time) on each Calculation Date, the Canadian Administrative Agent shall determine the Exchange Rate with respect to Canadian Dollars as of such Calculation Date and deliver to the U.S. Administrative Agent in writing the U.S. Dollar equivalent amount of such determination on or prior to the Reset Date (as defined below), and (ii) 1:00 p.m. (Oslo, Norway time) on each Calculation Date, the Norwegian Administrative Agent shall determine the Exchange Rate with respect to Norwegian Krone as of such Calculation Date and deliver to the U.S. Administrative Agent in writing the U.S. Dollar equivalent amount of such determination on or prior to the Reset Date (as defined below). The Exchange Rate so determined shall become effective on the second Business Day immediately following the relevant Calculation Date (a "Reset Date") and shall remain effective until the next succeeding Calculation Date. Not later than 4:00 p.m. (Houston, Texas time) on each Reset Date, the U.S. Administrative Agent shall consult with the Canadian Administrative Agent and Norwegian Administrative Agent regarding the Exchange Rate and the Administrative Agents shall determine the Total Canadian Exposure, Total Norwegian Exposure and the aggregate U.S. Obligations. If, on any Reset Date or on the date of any reallocation of the U.S. Commitments, Canadian Commitments and Norwegian Commitments pursuant to Section 2.5(c) hereof, the sum of the aggregate U.S. Obligations, the Total Canadian Exposure and the Total Norwegian Exposure exceeds the aggregate of all of the U.S. Commitments, Canadian Commitments and Norwegian Commitments by five percent (5%) or more, then (i) the Administrative Agents shall give notice thereof to the Lenders and Borrowers and (ii) the Borrowers shall within three Business Days thereafter, repay or prepay Loans (or provide Cover for Letter of Credit Liabilities or Bankers' Acceptance Liabilities) in accordance with this Agreement in an 45

aggregate principal amount sufficient to reduce the sum of the aggregate U.S. Obligations, the Total Canadian Exposure and the Total Norwegian Exposure to the aggregate of all of the U.S. Commitments, Canadian Commitments and Norwegian Commitments. If, on any Reset Date prior to the Termination Date, the Total Canadian Exposure exceeds the aggregate of all of the Canadian Commitments by five percent (5%) or more, then (i) the Canadian Administrative Agent shall give notice thereof to Canadian Borrowers and the Canadian Lenders and (ii) within three Business Days thereafter, Canadian Borrowers shall repay or prepay Canadian Loans (or provide Cover for Letter of Credit Liabilities relating to Canadian Letters of Credit or Bankers' Acceptance Liabilities) in accordance with this Agreement in an aggregate principal amount such that, after giving effect thereto, the Total Canadian Exposure shall not exceed the aggregate of all of the Canadian Commitments.

INCREASE OF COMMITMENT. On any date occurring on or prior to the Maturity Date, the Borrowers may increase the aggregate of the Revolving Commitments by an amount not greater than US$25,000,000 (any such increase, a "Commitment Increase"), provided, however, that the aggregate Revolving Commitments shall not at any time exceed US$200,000,000, by (i) requesting one or more of the existing U.S. Lenders, Canadian Lenders or Norwegian Lenders (each of which, in its sole discretion, may determine whether and to what degree to participate in such Commitment Increase) to increase its Commitment (an "Increasing Lender") and/or (ii) by designating one or more other banks or other financial institutions reasonably acceptable to the U.S. Administrative Agent (an "Additional Lender") to become a party to this Agreement. The sum of the increases in the Revolving Commitments of the Increasing Lenders plus the Revolving Commitments of the Additional Lenders upon giving effect to the Commitment Increase shall not in the aggregate exceed the amount of the Commitment Increase. Borrower shall provide prompt notice of any proposed Commitment Increase pursuant to this Section 2.12 to the U.S. Administrative Agent, Canadian Administrative Agent, and Norwegian Administrative Agent and the Lenders, provided however, that the number of requests for a Commitment Increase shall be limited to two requests, each of which shall be in an amount equal to at least $10,000,000. The Borrowers shall allocate each Commitment Increase to the Canadian Commitments, Norwegian Commitments and the U.S. Commitments as set forth in such notice, and the sum of the resulting increase in the Canadian Commitments, Norwegian Commitments and the U.S. Commitments shall equal the amount of such Commitment Increase. 46

Any Commitment Increase shall become effective upon (i) the receipt by the U.S. Administrative Agent of (A) an agreement pertaining to such Commitment Increase in the form attached hereto as Exhibit M signed by Borrowers and each Increasing Lender, if any, (B) an agreement pertaining to such Commitment Increase in the form attached hereto as Exhibit N signed by Borrowers and each Additional Lender, if any, and (C) such evidence of appropriate authorization on the part of each Borrower with respect to the Commitment Increase and such opinions of counsel for each Borrower with respect to the Commitment Increase as the U.S. Administrative Agent may reasonably request, (ii) the funding by each Increasing Lender and Additional Lender of the U.S. Borrowings, Canadian Borrowings and Norwegian Borrowings, to be made by each such U.S. Lender, Canadian Lender and Norwegian Lender, as the case may be, and each Increasing Lender and each Additional Lender, if applicable described in subsection (c) below and (iii) receipt by the Administrative Agents of a certificate (the statements contained in which shall be true) of a Responsible Officer of the respective Borrower stating that both before and after giving effect to such Commitment Increase (A) no Event of Default has occurred and is continuing, and (B) all representations and warranties made by each Borrower in this Agreement are true and correct in all material respects, unless such representation or warranty relates to an earlier date. Upon the effective date of any Commitment Increase, each Increasing Lender and each Additional Lender shall provide funds to the applicable Administrative Agent, in the manner described in Section 3.1. The funds so provided by any U.S. Lender, Canadian Lender and Norwegian Lender, as the case may be, shall be deemed to be a U.S. Borrowing, Canadian Borrowing or Norwegian Borrowing, as the case may be, made by such U.S. Lender, Canadian Lender and Norwegian Lender on the date of such Commitment Increase, and in an amount such that after giving effect to such Commitment Increase and the U.S. Borrowing, Canadian Borrowing or Norwegian Borrowing made on the date of such Commitment Increase, each U.S. Borrowing, Canadian Borrowing or Norwegian Borrowing as the case may be, outstanding hereunder shall consist of U.S. Borrowing, Canadian Borrowing or Norwegian Borrowing as the case may be, made by the U.S. Lender, Canadian Lender and Norwegian Lender ratably in accordance with each U.S. Lender, Canadian Lender and Norwegian Lender's U.S. Commitment, Canadian Commitment and Norwegian Commitment, respectively. Notwithstanding any provision contained herein to the contrary, from and after the date of any Commitment Increase and the making of any U.S. Borrowing, Canadian Borrowing or Norwegian Borrowing as the case may be, on such date pursuant to subsection (b) above, all calculations and payments of interest on the U.S. Borrowing, Canadian Borrowing or Norwegian Borrowing as the case may be, shall take into account the actual Revolving Commitment of each U.S. Lender, Canadian Lender and Norwegian Lender and the actual principal amount outstanding of each U.S. Borrowing, Canadian Borrowing or Norwegian Borrowing made by such U.S. Lender, Canadian Lender and Norwegian Lender, as the case may be, during the relevant period of time. EXTENSION OF MATURITY DATE. Not earlier than 120 days prior to the Maturity Date, then in effect, nor later than 60 days prior to the Maturity Date, then in effect, the Borrowers may, upon notice to the 47

Administrative Agents (which shall promptly notify the Lenders), request a one-year extension of the Maturity Date then in effect. This option may be exercised only twice. Within 30 days of delivery of such notice, each Lender shall notify the applicable Administrative Agent whether or not it consents to such extension (which consent may be given or withheld in such Lender's sole and absolute discretion). Any Lender not responding within the above time period shall be deemed not to have consented to such extension. The Administrative Agents shall promptly notify each Borrower and the Lenders of the Lenders' responses. The Maturity Date shall be extended only if Lenders holding at least 66-2/3% of the Aggregate Commitments (the "Consenting Lenders") have consented thereto. If so extended, the Maturity Date, as to the Consenting Lenders, shall be extended to the same date in the following year, effective as of the Maturity Date then in effect (such extended Maturity Date being the "Extension Maturity Date"). All non-consenting Lenders ("Non-Consenting Lenders") shall continue to be subject to the Maturity Date in effect prior to the effectiveness of the Extension Maturity Date (such existing Maturity Date being the "Present Maturity Date"). The Administrative Agents and the Borrowers shall promptly confirm to the Lenders such extension and the Extension Maturity Date. As a condition precedent to such extension, the Borrowers shall pay or prepay all Loans, interest thereon and all other amounts due each Non-Consenting Lender on or before the Present Maturity Date (and each Non-Consenting Lender shall, as of the Present Maturity Date, be released of all obligations (i) with respect to Letter of Credit Liabilities and U.S. Swing Line Borrowings, and (ii) to reimburse draws or fund participations under Section 2.3, and shall deliver to the Administrative Agents a certificate of each Borrower (in sufficient copies for each Lender) signed by a Responsible Officer of such Borrower (i) certifying and attaching the resolutions adopted by such Borrower approving or consenting to such extension and (ii) certifying that, before and after giving effect to such extension, (A) the representations and warranties contained in Article VI and the other Loan Documents are true and correct in all material respects, except to the extent that such representations and warranties specifically refer to an earlier date, in which case they are true and correct in all material respects as of such earlier date, and except that for purposes of this Section 2.13, the representations and warranties contained in subsections (a) and (b) of Section 6.2 shall be deemed to refer to the most recent statements furnished pursuant to subsections (a) and (b), respectively, of Section 7.2, and (B) no Default exists. This Section shall supersede any provisions in Section 4.5 or 11.5 to the contrary. The Borrowers shall prepay any Loans outstanding on the Extension Maturity Date (and pay any additional amounts required pursuant to Section 3.3(c)(iv)) or borrow additional amounts to the extent necessary to keep outstanding Loans ratable with any revised and new U.S. Commitment, Canadian Commitment or Norwegian Commitment, as the case may be, of all Consenting Lenders effective as of the Extension Maturity Date. BORROWINGS, PREPAYMENTS AND INTEREST OPTIONS BORROWINGS. The applicable Borrower shall give the applicable Administrative Agent notice of each borrowing to be made hereunder as provided in Section 4.3 hereof and the applicable Administrative Agent shall promptly notify each applicable Lender of such request. Not later 48

Such amounts received by the applicable Administrative Agent will be held in an account maintained by the applicable Borrower with the applicable Administrative Agent. The amounts so received by the applicable Administrative Agent shall, subject to the terms and conditions of this Agreement, be made available to the applicable Borrower by wiring or otherwise transferring, in immediately available funds, such amount to an account designated by the applicable Borrower and approved by the applicable Administrative Agent. PREPAYMENTS. OPTIONAL PREPAYMENTS. Except as provided in Section 3.3 hereof, each Borrower shall have the right to prepay, on any Business Day, in whole or in part, without the payment of any penalty or fee, any of the Obligations (other than Obligations relating to Bankers' Acceptances) at any time or from time to time, provided that the applicable Borrower shall give the applicable Administrative Agent notice of each such prepayment as provided in Section 4.3 hereof. Each partial optional prepayment on a Loan shall be in an amount equal to at least US$3,000,000 or any an integral multiple of US$1,000,000 in excess thereof (in respect of Loans denominated in Dollars) or C$3,000,000 or any an integral multiple of C$1,000,000 in excess thereof (in respect of Loans denominated in Canadian Dollars) or NOK30,000,000 or any integral multiple of NOK10,000,000 in excess thereof (in respect of Loans denominated in Norwegian Krone) and shall include accrued interest up to such date of prepayment. Bankers' Acceptances may not be prepaid. INTEREST PAYMENTS. Accrued and unpaid interest on the unpaid principal balance of the Notes shall be due and payable on the Interest Payment Dates. PAYMENTS AND INTEREST ON REIMBURSEMENT OBLIGATIONS. Each Borrower will pay to the applicable Administrative Agent for the account of each applicable Lender the amount of each Reimbursement Obligation with respect to such Borrower on the date on which the applicable Administrative Agent notifies the applicable Borrower of the date and amount of the applicable payment by the Issuer of any drawing under a Letter of Credit or payment of any Bankers' Acceptance on maturity. The amount of any Reimbursement Obligation may, if the applicable conditions precedent specified in Sections 5.1 and 5.2 hereof have been satisfied, be paid with the proceeds of Loans or, in the case of Canadian Obligations, of the acceptance and purchase of Bankers' Acceptances. Subject to Section 11.7 hereof, each Borrower will pay to the applicable Administrative Agent for the account of each applicable Lender interest on any Reimbursement Obligation at (i) at the applicable Base Rate (with respect to Reimbursement Obligations denominated in Dollars) or at the Canadian Prime 49

Rate (with respect to Reimbursement Obligations denominated in Dollars) plus the applicable Margin Percentage from the date such Reimbursement Obligation arises until the date five (5) Business Days thereafter and (ii) at the applicable Default Rate thereafter until the same is paid in full. INTEREST; ETC. INTEREST; OPTIONS AVAILABLE. The outstanding principal balance of the U.S. Note shall bear interest at the applicable Base Rate; the outstanding principal balance of the Canadian Dollar Notes shall bear interest at the Canadian Prime Rate and the outstanding principal balance of the Norwegian Krone Note shall bear interest at the Norwegian Prime Rate; provided, that (1) all past due amounts, both principal and accrued interest, for any of the Notes, shall bear interest at the Default Rate, (2) upon the direction of the Majority Lenders, while any Default or Event of Default has occurred or is continuing, all Obligations shall bear interest at the Default Rate and (3) subject to the provisions hereof, the U.S. Borrower, each Canadian Borrower and Norwegian Borrower shall have the option of having all or any portion of the principal balances of its Notes (other than the Canadian Dollar Notes or Norwegian Krone Notes) from time to time outstanding bear interest at a Eurodollar Rate and Norwegian Borrower shall also have the option of having all or any portion of the principal balances of its Notes from time to time outstanding bear interest at a Eurokrone Rate. The records of Administrative Agents and each of the Lenders with respect to Interest Options, Interest Periods and the amounts of Loans to which they are applicable shall be binding and conclusive, absent manifest error. Interest on the amount of each advance against the Notes shall be computed on the amount of that advance and from the date it is made. Notwithstanding anything in this Agreement to the contrary, for the full term of the Notes the interest rate produced by the aggregate of all sums paid or agreed to be paid to any holder of a Note for the use, forbearance or detention of the debt evidenced thereby (including all interest on the Notes at the Stated Rate plus the Additional Interest) shall not exceed the Ceiling Rate, if any, for such holder. DESIGNATION AND CONVERSION. Each Borrower shall have the right to designate or convert its Interest Options in accordance with the provisions hereof. Provided no Event of Default has occurred and is continuing and subject to the last sentence of Section 3.3(a) and the provisions of Section 3.3(c), the U.S. Borrower and either Canadian Borrower may elect to have a Eurodollar Rate apply or continue to apply to all or any portion of the principal balance of its Notes (other than the Canadian Dollar Notes) and Norwegian Borrower may elect to have a Eurokrone Rate apply or continue to apply to all or any portion of the principal balance of its Notes. Each change in Interest Options shall be a conversion of the rate of interest applicable to the specified portion of the Loans, but such conversion shall not change the respective outstanding principal balances of the applicable Notes. The Interest Options shall be designated or converted in the manner provided below: The applicable Borrower shall give the applicable Administrative Agent telephonic notice, promptly confirmed by a Rate Designation Notice (and the applicable Administrative Agent shall promptly inform each applicable Lender thereof). Each such telephonic and written notice shall specify the amount of the Loan which is the subject of the designation, if any; the amount of borrowings into which such borrowings are to be converted or for which an Interest Option is 50

designated; the proposed date for the designation or conversion and the Interest Period or Periods, if any, selected by the applicable Borrower. Such telephonic notice shall be irrevocable and shall be given to the applicable Administrative Agent no later than the applicable Rate Designation Date. No more than five (5) LIBOR Borrowings shall be in effect with respect to the U.S. Loans at any time, no more than 3 LIBOR Borrowings shall be in effect with respect to the Canadian Loans at any time and no more than 5 LIBOR Borrowings shall be in effect with respect to the Norwegian Loans at any time. No single LIBOR Borrowing may include both U.S. Loans and Canadian Loans or Norwegian Loans. Each designation or conversion of a LIBOR Borrowing shall occur on a LIBOR Business Day. Each designation or conversion of a NIBOR Borrowing shall occur on a NIBOR Business Day. Except as provided in Section 3.3(c) hereof, no LIBOR Borrowing shall be converted to a Base Rate Borrowing or another LIBOR Borrowing on any day other than the last day of the applicable Interest Period. Each request for a Base Rate Borrowing shall be in the amount at least equal to the lesser of (1) the unutilized portion of the U.S. Commitments or (2) US$500,000 and an integral multiple of US$100,000 in excess thereof. Each request for a LIBOR Borrowing shall be in the amount at least equal to the lesser of (1) the unutilized portion of the U.S. Commitments, Canadian Commitments or Norwegian Commitments, as the case may be or (2) US$5,000,000 and an integral multiple of US$1,000,000 in excess thereof. Each request for a NIBOR Borrowing shall be in the amount at least equal to the lesser of (1) the unutilized portion of the Norwegian Commitments or (2) NOK50,000,000 and an integral multiple of NOK10,000,000 in excess thereof. Each designation of an Interest Option with respect to the U.S. Notes shall apply to all of the U.S. Notes ratably in accordance with their respective outstanding principal balances. Each designation of an Interest Option with respect to the Canadian Notes shall apply to all of the Canadian Notes ratably in accordance with their respective outstanding principal balances. If any Lender assigns an interest in any of its Notes when any LIBOR Borrowing is outstanding with respect thereto, then such assignee shall have its ratable interest in such LIBOR Borrowing. The entire outstanding principal balance of the Canadian Dollar Notes shall bear interest at the Canadian Prime Rate. The entire outstanding principal balance of the Banker's Acceptances shall bear interest at the Applicable BA Discount Rate. The entire outstanding balance of the Norwegian Krone Notes shall bear interest at the Norwegian Prime Rate. SPECIAL PROVISIONS APPLICABLE TO LIBOR BORROWINGS AND NIBOR BORROWINGS. Options Unlawful. If the adoption of any applicable Legal Requirement after the Effective Date or any change after the Effective Date in any applicable Legal Requirement or in the interpretation or administration thereof by any Governmental Authority or compliance by any Lender with any request or directive (whether or not having the force of law) issued after the Effective Date by any central bank or other Governmental Authority shall at any time make it unlawful or impossible for any Lender to permit the establishment of or to maintain any LIBOR Borrowing or NIBOR Borrowing, the commitment of such Lender to establish or maintain such LIBOR Borrowing or 51

NIBOR Borrowing shall forthwith be suspended and the applicable Borrower shall forthwith, upon demand by the applicable Administrative Agent to such Borrower, (1) convert the LIBOR Borrowing or NIBOR Borrowing of such Lender with respect to which such demand was made to a Base Rate Borrowing; (2) pay all accrued and unpaid interest to date on the amount so converted; and (3) pay any amounts required to compensate such Lender for any additional cost or expense which such Lender may incur as a result of such adoption of or change in such Legal Requirement or in the interpretation or administration thereof and any Funding Loss which any Lender may incur as a result of such conversion. If, when any Administrative Agent so notifies any Borrower, such Borrower has given a Rate Designation Notice specifying a LIBOR Borrowing or NIBOR Borrowing but the selected Interest Period has not yet begun, as to the applicable Lender such Rate Designation Notice shall be deemed to be of no force and effect, as if never made, and the balance of the Loans made by such Lender specified in such Rate Designation Notice shall bear interest at the Base Rate until a different available Interest Option shall be designated in accordance herewith. Increased Cost of Borrowings. If the adoption after the Effective Date of any applicable Legal Requirement or any change after the Effective Date in any applicable Legal Requirement or in the interpretation or administration thereof by any Governmental Authority or compliance by any Lender with any request or directive (whether or not having the force of law) issued after the Effective Date by any central bank or Governmental Authority shall at any time as a result of any portion of the principal balances of the Notes being maintained on the basis of a Eurodollar Rate or Eurokrone Rate, as the case may be: subject any Lender to any Taxes (to the extent not covered by Section 4.1(d)), on or from any payment due under any LIBOR Borrowing or NIBOR Borrowing or other amount due hereunder, other than income, revenue and franchise taxes of the United States or its political subdivisions or such other jurisdiction in which the applicable Lender has its principal office or applicable lending office; or change the basis of taxation of payments due from any Borrower to any Lender under any LIBOR Borrowing or NIBOR Borrowing (otherwise than by a change in the rate of franchise taxes or taxation based on income or revenues of such Lender); or impose, modify, increase or deem applicable any reserve requirement (excluding that portion of any reserve requirement included in Section 3.3(g) or Section 3.3(h)), special deposit requirement or similar requirement (including, but not limited to, state law requirements and Regulation D) against assets of any Lender, or against deposits with any Lender, or against loans made by any Lender, or against any other funds, obligations or other Property owned or held by any Lender; or impose on any Lender any other condition regarding any LIBOR Borrowing or NIBOR Borrowing (other than any condition generally applicable to all Loans); and the result of any of the foregoing is to increase the cost to any Lender of agreeing to make or of making, renewing or maintaining such LIBOR Borrowing or NIBOR Borrowing, or reduce the amount of principal or interest received by any Lender, then, within 15 Business Days after demand by any Administrative Agent (accompanied by a statement setting forth in reasonable detail the applicable Lender's basis therefor), the applicable Borrower shall pay to the applicable Administrative Agent additional amounts which shall compensate each Lender for such increased cost or reduced amount. The determination by any Lender of the amount of any such increased 52

cost, increased reserve requirement or reduced amount shall be conclusive and binding, absent manifest error. Each Borrower shall have the right, if it receives from any Administrative Agent any notice referred to in this paragraph, upon three Business Days' notice to the applicable Administrative Agent (which shall notify each affected Lender), either (i) to repay in full (but not in part) any borrowing with respect to which such notice was given, together with any accrued interest thereon, or (ii) to convert the LIBOR Borrowing or NIBOR Borrowing which is the subject of the notice to a Base Rate Borrowing; provided, that any such repayment or conversion shall be accompanied by payment of (x) the amount required to compensate each Lender for the increased cost or reduced amount referred to in the preceding paragraph; (y) all accrued and unpaid interest to date on the amount so repaid or converted, and (z) any Funding Loss which any Lender may incur as a result of such repayment or conversion. Each Lender will notify the applicable Borrower through the applicable Administrative Agent of any event occurring after the date of this Agreement which will entitle such Lender to compensation pursuant to this Section as promptly as practicable after it obtains knowledge thereof and determines to request such compensation, and (if so requested by the applicable Borrower through the applicable Administrative Agent) will designate a different lending office of such Lender for the applicable LIBOR Borrowing or NIBOR Borrowing or will take such other action as the applicable Borrower may reasonably request if such designation or action is consistent with the internal policy of such Lender and legal and regulatory restrictions, will avoid the need for, or reduce the amount of, such compensation and will not, in the sole opinion of such Lender, be disadvantageous to such Lender. Inadequacy of Pricing and Rate Determination. If, for any reason with respect to any Interest Period, any applicable Administrative Agent (or, in the case of clause 2 below, Lenders having 50% or more of the Aggregate Commitments relating to the affected Tranche) shall have determined (which determination shall be conclusive and binding upon each Borrower, absent manifest error) that: the applicable Administrative Agent is unable through its customary general practices to determine any applicable Eurodollar Rate or Eurokrone Rate, as the case may be, or any applicable Eurodollar Rate or Eurokrone Rate, as the case may be, will not adequately and fairly reflect the cost to the applicable Lenders of making and maintaining such LIBOR Borrowing or NIBOR Borrowing hereunder for any proposed Interest Period, then the applicable Administrative Agent shall give the applicable Borrower notice thereof and thereupon, (A) any Rate Designation Notice previously given by such Borrower designating the applicable LIBOR Borrowing or NIBOR Borrowing which has not commenced as of the date of such notice from any Administrative Agent shall be deemed for all purposes hereof to be of no force and effect, as if never given, and (B) until the applicable Administrative Agent shall notify such Borrower that the circumstances giving rise to such notice from such Administrative Agent no longer exist, each Rate Designation Notice requesting the applicable Eurodollar Rate or Eurokrone Rate, as the case may be, shall be deemed a request for a Base Rate Borrowing, and any applicable LIBOR Borrowing or NIBOR Borrowing then outstanding shall be converted, without any notice to or from any Borrower, upon the termination of the Interest Period then in effect with respect to it, to a Base Rate Borrowing. Funding Losses. Each Borrower shall indemnify each applicable Lender against and hold each applicable Lender harmless from any Funding Loss relating to Loans to such Borrower or relating 53

to Bankers' Acceptances requested by such Borrower. This indemnity shall survive the payment of the Notes. A certificate of any Lender (explaining in reasonable detail the amount and calculation of the amount claimed) as to any additional amounts payable pursuant to this paragraph submitted to the applicable Borrower shall be conclusive and binding upon such Borrower, absent manifest error. FUNDING OFFICES; ADJUSTMENTS AUTOMATIC; CALCULATION YEAR. Any Lender may, if it so elects, fulfill its obligation as to any LIBOR Borrowing or NIBOR Borrowing by causing a branch or affiliate of such Lender to make such Loan and may transfer and carry such Loan at, to or for the account of any branch office or affiliate of such Lender; provided, that in such event for the purposes of this Agreement such Loan shall be deemed to have been made by such Lender and the obligation of the applicable Borrower to repay such Loan shall nevertheless be to such Lender and shall be deemed held by it for the account of such branch or affiliate. Without notice to any Borrower or any other Person, each rate required to be calculated or determined under this Agreement shall automatically fluctuate upward and downward in accordance with the provisions of this Agreement. Interest based on the Base Rate, Canadian Prime Rate or any applicable Prime Rate shall be computed on the basis of the actual number of days elapsed in a year consisting of 365 or 366 days, as the case may be. All other interest required to be calculated or determined under this Agreement including LIBOR Borrowings and NIBOR Borrowings shall be computed on the basis of the actual number of days elapsed in a year consisting of 360 days, unless the Ceiling Rate would thereby be exceeded, in which event, to the extent necessary to avoid exceeding the Ceiling Rate, the applicable interest shall be computed on the basis of the actual number of days elapsed in the applicable calendar year in which such interest accrued. FUNDING SOURCES. Notwithstanding any provision of this Agreement to the contrary, each Lender shall be entitled to fund and maintain its funding of all or any part of the Loans in any manner it sees fit, it being understood, however, that for the purposes of this Agreement all determinations hereunder shall be made as if each Lender had actually funded and maintained each LIBOR Borrowing or NIBOR Borrowing during each Interest Period through the purchase of deposits having a maturity corresponding to such Interest Period and bearing an interest rate equal to the Eurodollar Rate or Eurokrone Rate, as the case may be, for such Interest Period. ADDITIONAL INTEREST ON LIBOR ADVANCES. If any Lender is required by any Legal Requirement to maintain reserves with respect to liabilities or assets consisting of or including Eurocurrency Liabilities, and if as a result thereof there is an increase in the cost to such Lender of agreeing to make or making, funding or maintaining any LIBOR Borrowing, then the Borrower that borrowed such Borrowing shall from time to time, upon demand by such Lender (with a copy of such demand to the U.S. Administrative Agent), pay to the U.S. Administrative Agent for the account of such Lender additional amounts, as additional interest hereunder, sufficient to compensate such Lender for such increased cost. ADDITIONAL INTEREST ON NIBOR ADVANCES. Without duplication of Section 3.3(c) hereof, if by reason of: (A) changes in any existing law, rule or regulation, or (B) the adoption of any new law, rule or regulation, or (C) any change in the interpretation or administration of (A) or (B) 54

above by any governmental authority, or (D) compliance with any directive or request from any governmental authority (whether or not having the force of law): the Norwegian Lender incurs a cost as a result of it having entered into this Agreement and/or performing its obligations hereunder; or (i) there is an increase in the cost to the Norwegian Lender of maintaining or funding a NIBOR Borrowing; or (ii) the Norwegian Lender becomes liable for any new taxes (other than on net income) calculated by reference to any NIBOR Borrowing; or the Norwegian Lender becomes subject to any new or modified capital adequacy or similar requirements which will have the effect of increasing the amount of capital required or expected to be maintained by the Norwegian Lender based on the Norwegian Lender's obligations hereunder; or the Norwegian Lender's effective return hereunder is reduced in any other manner; then any such cost, liability or reduction of return as referred to in the preceding paragraphs (i)-(v) shall be payable by Norwegian Borrower upon request by the Norwegian Lender either in the form of an increased margin or in the form of an indemnification. The Norwegian Lender shall give Norwegian Borrower notice within a reasonable time of its intention to claim compensation under this Clause and it shall specify the form and amount of such compensation. The Norwegian Lender's determination of the amount of compensation to be made under this Clause shall, absent manifest error, be conclusive. Norwegian Borrower shall be entitled to prepay the NIBOR Borrowing in accordance with the terms of the Agreement. In such event Norwegian Borrower shall nevertheless compensate the Norwegian Lender for such requested indemnification for the period up to and including the date of prepayment. In the event that it shall be unlawful for the Norwegian Lender to make available or maintain a NIBOR Borrowing then the Norwegian Lender's obligations to lend in Krone shall terminate and all amounts owing by Norwegian Borrower to the Norwegian Lender in Krone shall become due and payable on demand, in each case to the extent necessary to not violate any law. Notwithstanding anything in this Section 3.3 to the contrary, under no circumstances will Norwegian Borrower be jointly and/or severally liable for any obligation or liability of U.S. Borrower or Canadian Borrowers, or both. PAYMENTS; PRO RATA TREATMENT; COMPUTATIONS, ETC. PAYMENTS; TAX FORMS. Except to the extent otherwise provided herein, all payments of principal, interest, Reimbursement Obligations and other amounts to be made by any Borrower hereunder, under the Notes and under the other Loan Documents shall be made in (iii) with respect to Bankers' Acceptance Liabilities and Canadian Prime Loans, Canadian Dollars (iv) with respect to NIBOR Borrowings, in Norwegian Krone and (v) in all other cases, in Dollars, without setoff or counterclaim and in same day funds, to the applicable Administrative Agent at its Principal Office (or in the case of a successor U.S. Administrative Agent, 55

Canadian Administrative Agent or Norwegian Administrative Agent, as the case may be, at the principal office of such successor Administrative Agent, as applicable, not later than 12:00 noon Houston, Texas time, 1:00 p.m. Calgary, Alberta time or 12:00 noon Oslo, Norway time, as applicable), each such payment made after such time on such due date to be deemed to have been made on the next succeeding Business Day. Each Borrower shall, at the time of making each payment hereunder, under any Note or under any other Loan Document, specify to the applicable Administrative Agent Obligations payable by such Borrower hereunder or thereunder to which such payment is to be applied. Each payment received by any Administrative Agent hereunder, under any Note or under any other Loan Document for the account of a Lender shall be paid promptly to such Lender (subject, however, to Section 2.8), in immediately available funds. If any Administrative Agent fails to send to any Lender the applicable amount by the close of business on the date any such payment is received by such Administrative Agent if such payment is received prior to 11:00 a.m. Houston, Texas time (in the case of any payment to a U.S. Lender), 12:00 noon Calgary, Alberta time (in the case of any payment to a Canadian Lender) or 12:00 noon Oslo, Norway time (in the case of any payment to a Norwegian Lender) (or on the next succeeding Business Day with respect to payments which are received after such time), such Administrative Agent shall pay to the applicable Lender interest on such amount from such date at a rate of interest per annum equal to (i) in respect of Obligations which are denominated in Dollars, the Federal Funds Rate and (ii) in respect of Canadian Obligations which are denominated in Canadian Dollars, the CDOR Rate and (iii) in respect of Norwegian Obligations which are denominated in Norwegian Krone, the NIBOR Rate. If the due date of any payment hereunder or under any other Loan Document falls on a day which is not a Business Day, the due date for such payments (except as otherwise provided in the definition of "Interest Period" set forth in Section 1.1 hereof) shall be extended to the next succeeding Business Day and interest shall be payable for any principal so extended for the period of such extension. (vi) Each U.S. Lender which is organized under the laws of a jurisdiction outside the United States shall, on the day of the initial borrowing from each such U.S. Lender hereunder and from time to time thereafter if requested by U.S. Borrower or U.S. Administrative Agent, provide U.S. Administrative Agent and U.S. Borrower with the forms prescribed by the Internal Revenue Service of the United States certifying as to such U.S. Lender's status for purposes of determining exemption from, or reduction of, United States withholding taxes with respect to all payments to be made to such U.S. Lender hereunder or other documents satisfactory to such U.S. Lender, U.S. Borrower and U.S. Administrative Agent indicating that all payments to be made to such U.S. Lender hereunder are not subject to United States withholding tax or are subject to such tax at a rate reduced by an applicable tax treaty adopted after such U.S. Lender became a U.S. Lender. Unless U.S. Borrower and U.S. Administrative Agent shall have received such forms or such documents indicating that payments to such U.S. Lender hereunder are not subject to United States withholding tax or are subject to such tax at a rate reduced by an 56

applicable tax treaty adopted after such U.S. Lender became a U.S. Lender, U.S. Borrower and U.S. Administrative Agent shall be entitled to withhold taxes from such payments at the applicable statutory rate. Except as provided in 4.1(d)(i), all payments by any Borrower hereunder or under any other Loan Document shall be made free and clear of and without deduction for or on account of any present or future income, stamp, or other taxes, fees, duties, withholding or other charges of any nature whatsoever imposed by any taxing authority excluding in the case of each Lender taxes imposed on or measured by its income or revenue or franchise taxes imposed by the United States or its political subdivisions or such other jurisdiction in which the applicable Lender is organized or has its principal office or through which it acts for purposes of this Agreement (such non-excluded items being hereinafter referred to as "Taxes"). If the making of such payments by any Borrower is prohibited by law unless such a tax, levy, impost or other charge is deducted or withheld therefrom, the applicable Borrower shall pay to the relevant Administrative Agent, on the date of each such payment, such additional amounts (without duplication of any amounts required to be paid by the applicable Borrower hereunder) as may be necessary in order that net amounts received by the Lenders after such deduction or withholding shall equal the amounts which would have been received if such deduction or withholding were not required. If as a result of any change in law (or the interpretation thereof) after the date that the applicable Lender became a "Lender" under this Agreement any withholding or deduction from any payment to be made to, or for the account of, a Lender by any Borrower hereunder or under any other Loan Document is required in respect of any Taxes pursuant to any applicable law, rule, or regulation, then such Borrower will (i) pay to the relevant authority the full amount required to be so withheld or deducted; (ii) to the extent available, promptly forward to the applicable Administrative Agent an official receipt or other documentation reasonably satisfactory to such Administrative Agent evidencing such payment to such authority; and (iii) pay to the applicable Administrative Agent, for the account of each affected Lender, such additional amount or amounts as are necessary to ensure that the net amount actually received by such Lender will equal the full amount such Lender would have received had no such withholding or deduction been required. Each Lender shall determine such additional amount or amounts payable to it (which determination shall, in the absence of manifest error, be conclusive and binding on each Borrower). If a Lender becomes aware that any such withholding or deduction from any payment to be made by any Borrower hereunder or under any other Loan Document is required, then such Lender shall promptly notify the applicable Administrative Agent and the applicable Borrower thereof stating the reasons therefor and the additional amount required to be paid under this Section. To the extent that any such withholding or deduction results from the failure of a Lender to provide a form required by Section 4.1(d)(i) hereof (unless such failure is due to some prohibition under applicable Legal Requirements), the applicable Borrower shall have no obligation to pay the additional amount required by clause (iii) above. Anything in this Section notwithstanding, if any Lender elects to require payment by any Borrower of any material amount under this Section, the applicable Borrower may, within 60 days after the date of receiving notice thereof and so long as no Default shall have occurred and be continuing, elect to terminate such Lender as a party to this Agreement; provided that, concurrently with such termination the applicable Borrower shall (i) if the Administrative Agents and each of the other Lenders shall consent, pay that Lender all principal, interest and fees and other amounts owed to such Lender through such date of termination or (ii) have arranged for another financial institution approved 57

by the Administrative Agents (such approval not to be unreasonably withheld) as of such date, to become a substitute Lender for all purposes under this Agreement in the manner provided in Section 11.6; provided further that, prior to substitution for any Lender, the applicable Borrower shall have given written notice to the Administrative Agents of such intention and the Lenders shall have the option, but no obligation, for a period of 60 days after receipt of such notice, to increase their Commitments in order to replace the affected Lender in lieu of such substitution. Each Canadian Lender is a resident of Canada for purposes of the Income Tax Act (Canada). Each Norwegian Lender is a resident of Norway for purposes of the Norwegian Act relating to Taxation on Property and Income of 26th March 1999 No. 14. PRO RATA TREATMENT. Except to the extent otherwise provided herein:(a) each borrowing from the Lenders under Section 2.1 hereof shall be made (x) in the case of Canadian Loans, ratably from the Canadian Lenders in accordance with their respective Canadian Commitments, (y) in the case of U.S. Loans, ratably from the U.S. Lenders in accordance with their respective U.S. Commitments and (z) in the case of Norwegian Loans, ratably from the Norwegian Lenders in accordance with their respective Norwegian Commitments; (b) each payment of Facility Fees shall be made for the account of the Lenders, and each termination or reduction of the U.S. Commitment, Canadian Commitment or Norwegian Commitment, as the case may be, of the applicable Lenders under Section 2.5 hereof shall be applied, pro rata, according to such Lenders' respective U.S. Commitment and/or Canadian Commitment and/or Norwegian Commitment, as the case may be; (c) each payment by any Borrower of principal of or interest on the Loans or any Bankers' Acceptance shall be made to the applicable Administrative Agent for the account of the applicable Lenders pro rata in accordance with the respective unpaid principal amounts of the Loans held by or Bankers' Acceptances accepted by such Lenders, and (d) the applicable Lenders (other than the applicable Issuer) shall purchase from the applicable Issuer participations in each Letter of Credit to the extent of their respective U.S. Commitment Percentages, Canadian Commitment Percentages or Norwegian Commitment Percentages, as the case may be. CERTAIN ACTIONS, NOTICES, ETC. Notices to the applicable Administrative Agent of any termination or reduction of Commitments and of borrowings and optional prepayments of Loans and requests for issuances of Letters of Credit shall be irrevocable and shall be effective only if received by the applicable Administrative Agent not later than 11:00 a.m. Houston, Texas time (in the case of U.S. Loans and U.S. Letters of Credit), 12:00 noon Calgary, Alberta time (in the case of Canadian Loans and Canadian Letters of Credit) or 12:00 noon Oslo, Norway time (in the case of Norwegian Loans and Norwegian Letters of Credit) on the number of Business Days prior to the date of the relevant termination, reduction, borrowing and/or prepayment specified below: Prior Notice Number of Business Days - ------------ ----------------------- Termination or Reduction of Commitments 5 Loan repayment 1 Swing Line Borrowings same day Base Rate Borrowings 1 Canadian Prime Loans same day 58

Letter of Credit issuance 3 Selection of a Eurodollar Rate 3 Selection of a Eurokrone Rate 4 NIBOR Borrowing 4 LIBOR Borrowing 3 Each such notice of termination or reduction shall specify the amount of the applicable Commitment to be terminated or reduced. Each such notice of borrowing or prepayment shall specify the amount of the Loans to be borrowed or prepaid and the date of borrowing or prepayment (which shall be a Business Day). The applicable Administrative Agent shall promptly notify the affected Lenders of the contents of each such notice. NON-RECEIPT OF FUNDS BY ANY ADMINISTRATIVE AGENT. Unless the applicable Administrative Agent shall have been notified by a Lender or a Borrower (the "Payor") prior to the date on which such Lender is to make payment to such Administrative Agent of the proceeds of a Loan (or funding of a drawing under a Letter of Credit or reimbursement with respect to any drawing under a Letter of Credit or funding of a payment under a Bankers' Acceptance or reimbursement with respect to any payment under a Bankers' Acceptance) to be made by it hereunder or the applicable Borrower is to make a payment to such Administrative Agent for the account of one or more of the Lenders, as the case may be (such payment being herein called the "Required Payment"), which notice shall be effective upon receipt, that the Payor does not intend to make the Required Payment to such Administrative Agent, the applicable Administrative Agent may assume that the Required Payment has been made and may, in reliance upon such assumption (but shall not be required to), make the amount thereof available to the intended recipient on such date and, if the Payor has not in fact made the Required Payment to such Administrative Agent, the recipient of such payment (or, if such recipient is the beneficiary of a Letter of Credit, the applicable Borrower and, if such Borrower fails to pay the amount thereof to the applicable Administrative Agent forthwith upon demand, the applicable Lenders ratably in proportion to their respective Commitment Percentages) shall, on demand, pay to such Administrative Agent the amount made available by such Administrative Agent, together with interest thereon in respect of the period commencing on the date such amount was so made available by such Administrative Agent until the date Administrative Agent recovers such amount at a rate of interest per annum equal to (i) in respect of Obligations which are denominated in Dollars, the Federal Funds Rate, (ii) in respect of Canadian Obligations which are denominated in Canadian Dollars, the CDOR Rate and (iii) in respect of Norwegian Obligations which are denominated in Norwegian Krone , the NIBOR Rate. SHARING OF PAYMENTS, ETC. If any of the U.S. Lender, Canadian Lender or Norwegian Lender (the U.S. Lenders collectively, Canadian Lenders collectively and Norwegian Lenders collectively, each a class) shall obtain payment of any principal of or interest on any Loan made by it under this Agreement, on any Reimbursement Obligation or on any other Obligation then due to such Lender hereunder, through the exercise of any right of set-off (including, without limitation, any right of setoff or Lien granted under Section 9.2 hereof), 59

banker's Lien, counterclaim or similar right, or otherwise, it shall promptly purchase from the other Lenders of such class participations in the Loans made by such other Lenders, or Reimbursement Obligations or other Obligations held by such other Lenders in such amounts, and make such other adjustments from time to time as shall be equitable to the end that all the Lenders of such class shall share the benefit of such payment (net of any expenses which may be incurred by such Lender in obtaining or preserving such benefit) pro rata in accordance with the unpaid Obligations then due to each of them. To such end all the Lenders of a class shall make appropriate adjustments among themselves (by the resale of participations sold or otherwise) if such payment is rescinded or must otherwise be restored. Each Borrower agrees, to the fullest extent it may effectively do so under applicable law, that any Lender so purchasing a participation in the Loans made, or Reimbursement Obligations or other Obligations held, by other Lenders may exercise all rights of set-off, bankers' Lien, counterclaim or similar rights with respect to such participation as fully as if such Lender were a direct holder of Loans, Reimbursement Obligations or other Obligations in the amount of such participation. Nothing contained herein shall require any Lender to exercise any such right or shall affect the right of any Lender to exercise, and retain the benefits of exercising, any such right with respect to any other indebtedness or obligation of any Borrower. REPLACEMENT OF LENDERS. Under any circumstances set forth herein providing that the Borrowers shall have the right to replace a Lender as a party to this Agreement, the Borrowers may, upon notice to such Lender and the U.S. Administrative Agent, replace such Lender by causing such Lender to assign its U.S. Commitment, Canadian Commitment or Norwegian Commitment, as the case may be, pursuant to Section 11.6 to one or more other Lenders procured by the Borrowers. The Borrowers shall (x) pay in full all principal, interest, fees and other amounts owing to such Lender through the date of replacement (including any amounts payable pursuant to Section 3.3(c)), (y) provide appropriate assurances and indemnities (which may include letters of credit) to the applicable Issuing Bank and the U.S. Swing Line Lender, as the case may be, as each may reasonably require with respect to any continuing obligation to fund participation interests in any Letters of Credit Liabilities or any U.S. Swing Line Borrowings or Canadian Swing Line Borrowings, as the case may be, then outstanding, and (z) release such Lender from its obligations under the Loan Documents.

REPRESENTATIONS AND WARRANTIES 62

To induce the Lenders to enter into this Agreement and to make the Loans and issue or participate in the Letters of Credit and accept and purchase Bankers' Acceptances, Parent, and with respect to its own individual entity only, U.S. Borrower, Canadian Borrowers and Norwegian Borrower, represents and warrants (such representations and warranties to survive any investigation and the making of the Loans and the issuance of any Letters of Credit and the acceptance and purchase of any Bankers' Acceptances) to the Lenders and Administrative Agents as follows: ORGANIZATION. Each Obligor (a) is duly organized, validly existing and in good standing under the laws of the jurisdiction of its organization; (b) has all necessary power and authority to conduct its business in all material respects as presently conducted, and (c) is duly qualified to do business and in good standing in the jurisdiction of its organization and in all jurisdictions in which the failure to so qualify would reasonably be expected to have a Material Adverse Effect.

default under, any material agreement or instrument by which any Obligor or any of its Property may be bound, and (e) do not and will not result in the creation of any Lien upon any Property of any Obligor, except as expressly contemplated herein. All necessary permits, registrations and consents for such making and performance have been obtained. OTHER DEBT.

LITIGATION. There is no litigation or administrative proceeding, to the knowledge of any executive officer of any Obligor, pending or threatened against, nor any outstanding judgment, order or decree against, any Obligor before or by any Governmental Authority which does or would reasonably be expected to have a Material Adverse Effect.

REGULATIONS T, U AND X. None of the proceeds of any Loan or proceeds from the acceptance and purchase of Bankers' Acceptances will be used for the purpose of purchasing or carrying directly or indirectly any margin stock or for any other purpose that would constitute this transaction a "purpose credit" within the meaning of Regulations T, U and X of the Board of Governors of the Federal Reserve System, as any of them may be amended from time to time. SUBSIDIARIES. As of the Effective Date, (i) Parent has no Subsidiaries other than as set forth on Schedule 6.8 hereto, and (ii) the percentage of the issued and outstanding equity interests in each applicable Subsidiary which is owned, as of the Effective Date, by Parent or one or more of its Subsidiaries is set forth on Schedule 6.8 hereto.

ERISA. With respect to each Plan, each Borrower and each member of the Controlled Group have fulfilled their obligations, including obligations under the minimum funding standards of ERISA and the Code and are in compliance in all material respects with the provisions of ERISA and the Code. No event has occurred which could result in a liability of any Borrower or any member of the Controlled Group to the PBGC or a Plan (other than to make contributions in the ordinary course) that would reasonably be expected to have a Material Adverse Effect. There have not been any nor are there now existing any events or conditions that would cause any Lien provided under ERISA to attach to any Property of any 64

Borrower or any member of the Controlled Group. Unfunded Liabilities as of the date hereof do not exceed US$5,000,000. No non-exempt "prohibited transaction" has occurred with respect to any Plan.

Each Obligor has, to the best knowledge of their respective executive officers, obtained and maintained in effect all Environmental Permits (or the applicable Person has initiated the necessary steps to transfer the Environmental Permits into its name or obtain such permits), the failure to obtain which would reasonably be expected to have a Material Adverse Effect. Each Obligor and its Properties, business and operations have been and are, to the best knowledge of their respective executive officers, in compliance with all applicable Requirements of Environmental Law and Environmental Permits the failure to comply with which would reasonably be expected to have a Material Adverse Effect. Each Obligor and its Properties, business and operations are not subject to any (A) Environmental Claims or (B), to the best knowledge of their respective executive officers (after making reasonable inquiry of the personnel and records of their respective Corporations), Environmental Liabilities, in either case direct or contingent, arising from or based upon any act, omission, event, condition or circumstance occurring or existing on or prior to the date hereof which would reasonably be expected to have a Material Adverse Effect. None of the officers of any Obligor has received any notice of any violation or alleged violation of any Requirements of Environmental Law or Environmental Permit or any Environmental Claim in connection with its Properties, liabilities, condition (financial or otherwise), business or operations which would reasonably be expected to have a Material Adverse Effect. Neither U.S. Borrower, Canadian Borrowers nor Norwegian Borrower knows of any event or condition with respect to currently enacted Requirements of Environmental Laws presently scheduled to become effective in the future with respect to any of the Properties of any Obligor which would reasonably be expected to have a Material Adverse Effect, for which the applicable Obligor has not made good faith provisions in its business plan and projections of financial performance.

Service or any Governmental Authority having jurisdiction under Applicable Canadian Pension Legislation, copies of each annual and other report with respect to each Plan or any trust created thereunder, (iii) immediately upon becoming aware of the occurrence of any "reportable event," as such term is used under ERISA for which the disclosure requirements have not been waived, or of any non-exempt "prohibited transaction," as such term is defined in Section 4975 of the Code, in connection with any Plan or any trust created thereunder, a written notice signed by the President or the principal financial officer of the applicable Borrower or the applicable member of the Controlled Group specifying the nature thereof, what action the applicable Borrower or the applicable member of the Controlled Group is taking or proposes to take with respect thereto, and, when known, any action taken by the PBGC, the Internal Revenue Service, the Department of Labor or any other applicable Governmental Authority with respect thereto, (iv) promptly after the filing or receiving thereof by any Borrower or any member of the Controlled Group of any notice of the institution of any proceedings or other actions which may result in the termination of any Plan, and (v) each request for waiver of the funding standards or extension of the amortization periods required by ERISA or Section 412 of the Code promptly after the request is submitted by Borrower or any member of the Controlled Group to the Secretary of the Treasury, the Department of Labor, the Internal Revenue Service or any other applicable Governmental Authority. To the extent required under applicable statutory funding requirements, each Borrower will fund, or will cause the applicable member of the Controlled Group to fund, all pension liabilities as they are incurred under the provisions of all Plans from time to time in effect, and comply with all applicable provisions of ERISA, in each case, except to the extent that failure to do the same would not reasonably be expected to have a Material Adverse Effect. Each Borrower covenants that it shall and shall cause each member of the Controlled Group to (1) make contributions to each Plan in a timely manner and in an amount sufficient to comply with the contribution obligations under such Plan and the minimum funding standards requirements of ERISA; (2) prepare and file in a timely manner all notices and reports required under the terms of ERISA including but not limited to annual reports; and (3) pay in a timely manner all required PBGC premiums, in each case, except to the extent that failure to do the same would not reasonably be expected to have a Material Adverse Effect.

purposes of the Parent, Borrowers and their respective Subsidiaries. Neither any Administrative Agent nor any Lender shall have any responsibility as to the use of any proceeds of the Loans or of the acceptance and purchase of Bankers' Acceptances. Each Borrower will not, nor will it permit any Subsidiary to, use any of the proceeds of the U.S. Borrowings, Canadian Borrowings and Norwegian Borrowings to purchase or carry any "margin stock" (as defined in Regulation U) that would cause any Lender to be in violation of Regulation U or any Borrower to be in violation of Regulation X of the Board of Governors of the Federal Reserve System. PARI PASSU. Cause Obligations under this Agreement and the other Loan Documents to rank at least pari passu with and, if other senior Borrowed Money Indebtedness is secured (other than by Permitted Liens), be equally and ratably secured as all such other senior Borrowed Money Indebtedness of the Borrowers and the Guarantor except for Borrowed Money Indebtedness secured by Permitted Liens; provided, however, that, nothing contained in this Section 7.12 is intended to permit any Liens or Borrowed Money Indebtedness not otherwise specifically provided for in this Agreement or to waive any rights with respect to any prohibitions on any Liens or Borrowed Money Indebtedness contained in this Agreement.

Create, incur, suffer or permit to exist, or assume or guarantee, directly or indirectly, or become or remain liable with respect to any Borrowed Money Indebtedness, whether direct, indirect, absolute, contingent or otherwise, except the following: Borrowed Money Indebtedness under this Agreement and the other Loan Documents and Borrowed Money Indebtedness secured by Liens permitted by Section 8.2 hereof; Borrowed Money Indebtedness existing on the date of this Agreement and listed on Exhibit K and Exhibit O attached hereto, and all renewals, extensions and replacements of any of the foregoing; Interest Rate Risk Indebtedness; other Borrowed Money Indebtedness not exceeding, in the aggregate for Parent and each of its Subsidiaries, at any one time outstanding (excluding Borrowed Money Indebtedness permitted by Section 8.1(a), (b), (c) or (e)), an amount equal to 20% of the Consolidated Net Worth of Parent and its Subsidiaries as of the last day of the immediately preceding fiscal quarter; provided, however, at the time such other Borrowed Money Indebtedness is incurred: Parent and its Subsidiaries shall be in compliance, on a pro forma basis after giving effect to such incurrence of additional Borrowed Money Indebtedness, with the covenants contained in this 70

Article VIII recomputed as of the last day of the most recently ended fiscal quarter of the Parent and its Subsidiaries as if the transaction in question had occurred on the first day of each relevant period for testing such compliance; The financial covenants of additional Borrowed Money Indebtedness are no more restrictive or burdensome than the covenants set forth in this Agreement; There shall be no required scheduled amortization of such additional Borrowed Money Indebtedness at any time that any Obligations shall remain unpaid, any Letter of Credit shall remain outstanding, or any Lender shall have any applicable U.S. Commitment, Canadian Commitment or Norwegian Commitment hereunder, except with respect to capital leases and indebtedness acquired or assumed in connection with an Acquisition permitted hereunder; The Obligations under this Agreement and the other Loan Documents of each Borrower and the Guarantor shall rank at least pari passu with and, if other senior Borrowed Money Indebtedness is secured (other than by Permitted Liens), be equally and ratably secured with such other Borrowed Money Indebtedness; and provided further that (x) capital leases and purchase money Borrowed Money Indebtedness (indebtedness secured by Liens) shall not exceed 5% of the Parent and its Subsidiaries Consolidated Net Worth at any time; and (y) the aggregate principal amount of all Borrowed Money Indebtedness of Subsidiaries of the Borrowers (excluding amounts available under the Increased Commitment) shall not exceed 5% of the Parent and its Subsidiaries Consolidated Net Worth at any time. Notwithstanding the above, if the Parent's S&P rating and Moody's rating both fall below BBB- or Baa3, respectively, then further Borrowed Money Indebtedness shall not be permitted under this Section 8.1(d) without Majority Lender approval, and in any event without limiting the foregoing under this Section, each Borrower agrees that all Borrowed Money Indebtedness owing by Parent to any of its Subsidiaries or owing by any Subsidiary of Parent to Parent or to any other Subsidiary of Parent shall be subordinated in a manner acceptable to the Majority Lenders and pursuant to documentation in Proper Form. Borrowed Money Indebtedness secured by assets assumed in connection with an Acquisition transaction permitted by Section 8.4 shall be permitted within 180 days from the consummation of the Acquisition; provided, however, that 180 days after giving effect to the Acquisition, the additional Borrowed Money Indebtedness incurred in the aggregate pursuant to an Acquisition, and permitted only by this Section 8.1(e), shall not exceed 5% of the Parent and its Subsidiaries Consolidated Net Worth at any time. LIENS.

RIGHT OF SETOFF. Upon the occurrence and during the continuance of any Event of Default, each Lender is hereby authorized at any time and from time to time, without notice to any Obligor (any such notice being expressly waived by U.S. Borrower, Canadian Borrowers, Norwegian Borrower and the other Obligors), to setoff and apply any and all deposits (general or special, time or demand, provisional or final but excluding the funds held in accounts clearly designated as escrow or trust accounts held by U.S. Borrower, Canadian Borrowers, Norwegian Borrower or any other Obligor for the benefit of Persons which are 76

not Obligors or Affiliates of any Obligor), whether or not such setoff results in any loss of interest or other penalty, and including without limitation all certificates of deposit, at any time held, and any other funds or Property at any time held, and other indebtedness at any time owing by such Lender to or for the credit or the account of U.S. Borrower, Canadian Borrowers, Norwegian Borrower or any other Obligor against any and all of the Obligations irrespective of whether or not such Lender or any Administrative Agent will have made any demand under this Agreement, the Notes or any other Loan Document. Should the right of any Lender to realize funds in any manner set forth above be challenged and any application of such funds be reversed, whether by court order or otherwise, each Lender, to the extent such Lender has received such funds, shall make restitution or refund to U.S. Borrower, Canadian Borrower or Norwegian Borrower or the applicable other Obligor, as the case may be, pro rata in accordance with their U.S. Commitments, Canadian Commitments or Norwegian Commitments, as the case may be. Each Lender agrees to promptly notify U.S. Borrower, Canadian Borrowers, Norwegian Borrower and Administrative Agents after any such setoff and application, provided that the failure to give such notice will not affect the validity of such setoff and application. The rights of Administrative Agents and the Lenders under this Section are in addition to other rights and remedies (including without limitation other rights of setoff) which Administrative Agents or the Lenders may have.

Such Proceeds of Remedies shall be held for the ratable benefit of the U.S. Lenders, the Canadian Lenders or Norwegian Lenders, as the case may be. The rights, titles, benefits, privileges, duties and obligations of the applicable Administrative Agent with respect thereto shall be governed by the terms and provisions of this Agreement. The applicable Administrative Agent may, but shall have no obligation to, invest any such Proceeds of Remedies in such manner as such Administrative Agent, in the exercise of its sole discretion, deems appropriate. Such Proceeds of Remedies shall be applied to Reimbursement Obligations arising in respect of any such Letters of Credit, the payment of any Lender's obligations under any such Letter of Credit and/or the Obligations relating to any such Bankers' Acceptance when such Letter of Credit is drawn upon or such Bankers' Acceptance matures, as the case may be.

Any such conversion shall be calculated so that the resulting Canadian Prime Loans shall be the equivalent on the date of conversion of the amount of Dollars so converted. Any accrued and unpaid interest denominated in Dollars at the time of any such conversion shall be similarly converted to Canadian Dollars, and such Canadian Prime Loans and accrued and unpaid interest thereon shall thereafter bear interest in accordance with the terms hereof. REMEDIES CUMULATIVE. No remedy, right or power conferred upon any Administrative Agent or any Lender is intended to be exclusive of any other remedy, right or power given 78

hereunder or now or hereafter existing at law, in equity, or otherwise, and all such remedies, rights and powers shall be cumulative. ADMINISTRATIVE AGENTS APPOINTMENT, POWERS AND IMMUNITIES. Each U.S. Lender hereby irrevocably appoints and authorizes U.S. Administrative Agent to act as its Administrative Agent hereunder, under the U.S. Letters of Credit and under the other Loan Documents with such powers as are specifically delegated to U.S. Administrative Agent by the terms hereof and thereof, together with such other powers as are reasonably incidental thereto. Each Canadian Lender hereby irrevocably appoints and authorizes Canadian Administrative Agent to act as its Administrative Agent hereunder, under the Canadian Letters of Credit and under the other Loan Documents with such powers as are specifically delegated to Canadian Administrative Agent by the terms hereof and thereof, together with such other powers as are reasonably incidental thereto. Each Norwegian Lender hereby irrevocably appoints and authorizes Norwegian Administrative Agent to act as its Administrative Agent hereunder, under the Norwegian Letters of Credit and under the other Loan Documents with such powers as are specifically delegated to Norwegian Administrative Agent by the terms hereof and thereof, together with such other powers as are reasonably incidental thereto. Any Loan Documents executed in favor of any Administrative Agent shall be held by such Administrative Agent for the ratable benefit of the applicable Lenders. None of the Administrative Agents ("Administrative Agents" as used in this Section 10 shall include reference to their Affiliates and their own and their Affiliates' respective officers, shareholders, directors, employees and Administrative Agents) (a) shall have any duties or responsibilities except those expressly set forth in this Agreement, the Letters of Credit, and the other Loan Documents, and shall not by reason of this Agreement or any other Loan Document be a trustee or fiduciary for any Lender; (b) shall be responsible to any Lender for any recitals, statements, representations or warranties contained in this Agreement, the Letters of Credit or any other Loan Document, or in any certificate or other document referred to or provided for in, or received by any of them under, this Agreement, the Letters of Credit or any other Loan Document, or for the value, validity, effectiveness, genuineness, enforceability, execution, filing, registration, collectibility, recording, perfection, existence or sufficiency of this Agreement, the Letters of Credit, or any other Loan Document or any other document referred to or provided for herein or therein or any Property covered thereby or for any failure by any Obligor or any other Person to perform any of its obligations hereunder or thereunder, or shall have any duty to inquire into or pass upon any of the foregoing matters; (c) shall be required to initiate or conduct any litigation or collection proceedings hereunder or under the Letters of Credit or any other Loan Document except to the extent requested and adequately indemnified by the Majority Lenders; (d) shall be responsible for any mistake of law or fact or any action taken or omitted to be taken by it hereunder or under the Letters or Credit or any other Loan Document or any other document or instrument referred to or provided for herein or therein or in connection herewith or therewith, including, without limitation, pursuant to its own negligence, except for its own gross negligence or willful misconduct; (e) shall be bound by or obliged to recognize any agreement among or between any Borrower and any Lender to which such Administrative Agent is not a party, regardless of whether such Administrative Agent has knowledge of the existence of any such agreement or the terms and provisions 79

thereof; (f) shall be charged with notice or knowledge of any fact or information not herein set out or provided to such Administrative Agent in accordance with the terms of this Agreement or any other Loan Document; (g) shall be responsible for any delay, error, omission or default of any mail, telegraph, cable or wireless agency or operator, and (h) shall be responsible for the acts or edicts of any Governmental Authority. Any Administrative Agent may employ Administrative Agents and attorneys-in-fact and none of the Administrative Agents shall be responsible for the negligence or misconduct of any such Administrative Agents or attorneys-in-fact selected by it with reasonable care. Without in any way limiting any of the foregoing, each Lender acknowledges that none of the Administrative Agents (nor any Issuer) shall have greater responsibility in the operation of the Letters of Credit than is specified in the Uniform Customs and Practice for Documentary Credits (1993 Revision, International Chamber of Commerce Publication No. 500). In any foreclosure proceeding concerning any collateral, if applicable, each holder of an Obligation if bidding for its own account or for its own account and the accounts of other Lenders is prohibited from including in the amount of its bid an amount to be applied as a credit against the Obligations held by it or the Obligations held by the other Lenders; instead, such holder must bid in cash only. However, in any such foreclosure proceeding, (i) U.S. Administrative Agent may (but shall not be obligated to) submit a bid for all U.S. Lenders (including itself) in the form of a credit against the U.S. Obligations, and U.S. Administrative Agent or its designee may (but shall not be obligated to) accept title to such collateral for and on behalf of all U.S. Lenders, (ii) Canadian Administrative Agent may (but shall not be obligated to) submit a bid for all Canadian Lenders (including itself) in the form of a credit against the Canadian Obligations, and Canadian Administrative Agent or its designee may (but shall not be obligated to) accept title to such collateral for and on behalf of all Canadian Lenders and (iii) Norwegian Administrative Agent may (but shall not be obligated to) submit a bid for all Norwegian Lenders (including itself) in the form of a credit against the Norwegian Obligations, and Norwegian Administrative Agent or its designee may (but shall not be obligated to) accept title to such collateral for and on behalf of all Norwegian Lenders. RELIANCE. Each Administrative Agent shall be entitled to rely upon any certification, notice or other communication (including any thereof by telephone, telex, telegram, electronic mail or cable) believed by it to be genuine and correct and to have been signed or sent by or on behalf of the proper Person or Persons, and upon advice and statements of legal counsel (which may be counsel for any Borrower), independent accountants and other experts selected by such Administrative Agent. None of the Administrative Agents shall be required in any way to determine the identity or authority of any Person delivering or executing the same. As to any matters not expressly provided for by this Agreement, the Letters of Credit, or any other Loan Document, each Administrative Agent shall in all cases be fully protected in acting, or in refraining from acting, hereunder and thereunder in accordance with instructions of the Majority Lenders, and any action taken or failure to act by U.S. Administrative Agent pursuant thereto shall be binding on all of the U.S. Lenders, any action taken or failure to act by Canadian Administrative Agent pursuant thereto shall be binding on all of the Canadian Lenders and any action taken or failure to act by Norwegian Administrative Agent pursuant thereto shall be binding on all of the Norwegian Lenders. If any order, writ, judgment or decree shall be made or entered by any court affecting the rights, duties and obligations of any Administrative Agent under this Agreement or any other Loan Document, then and in 80

any of such events such Administrative Agent is authorized, in its sole discretion, to rely upon and comply with such order, writ, judgment or decree which it is advised by legal counsel of its own choosing is binding upon it under the terms of this Agreement, the relevant Loan Document or otherwise; and if such Administrative Agent complies with any such order, writ, judgment or decree, then it shall not be liable to any Lender or to any other Person by reason of such compliance even though such order, writ, judgment or decree may be subsequently reversed, modified, annulled, set aside or vacated. DEFAULTS. None of the Administrative Agents shall be deemed to have knowledge of the occurrence of a Default (other than the non-payment of principal of or interest on Loans or Reimbursement Obligations) unless such Administrative Agent has received notice from a Lender or a Borrower specifying such Default and stating that such notice is a "Notice of Default." In the event that any Administrative Agent receives such a Notice of Default, such Administrative Agent shall give prompt notice thereof to the Lenders (and shall give each Lender prompt notice of each such non-payment). Each Administrative Agent shall (subject to Section 10.7 hereof) take such action with respect to such Notice of Default as shall be directed by the Majority Lenders and within its rights under the Loan Documents and at law or in equity, provided that, unless and until an Administrative Agent shall have received such directions, such Administrative Agent may (but shall not be obligated to) take such action, or refrain from taking such action, permitted hereby with respect to such Notice of Default as it shall deem advisable in the best interests of the Lenders and within its rights under the Loan Documents, at law or in equity. MATERIAL WRITTEN NOTICES. In the event that any Administrative Agent receives any written notice of a material nature from any Borrower or any Obligor under the Loan Documents, such Administrative Agent shall promptly inform each of the Lenders thereof. RIGHTS AS A LENDER. With respect to its Commitments and the Obligations, each of Wells Fargo, The Bank of Nova Scotia and Den norske Bank, ASA, in its capacity as a Lender hereunder, shall have the same rights and powers hereunder as any other Lender and may exercise the same as though it were not acting in its agency capacity, and the term "Lender" or "Lenders" shall, unless the context otherwise indicates, include each Administrative Agent in its individual capacity. Each Administrative Agent may (without having to account therefor to any Lender) accept deposits from, lend money to and generally engage in any kind of banking, trust, letter of credit, agency or other business with any Borrower (and any of their Affiliates) as if it were not acting as an Administrative Agent, and each Administrative Agent may accept fees and other consideration from any Borrower (in addition to the fees heretofore agreed to between any Borrower and any Administrative Agent) for services in connection with this Agreement or otherwise without having to account for the same to the Lenders. INDEMNIFICATION. The Canadian Lenders, Norwegian Lenders and the U.S. Lenders, respectively, agree to indemnify Canadian Administrative Agent, Norwegian Administrative Agent and U.S. Administrative Agent, respectively (to the extent not reimbursed under Section 2.3(c), Section 11.3 or Section 11.4 hereof, but without limiting the obligations of any Borrower under said Sections 2.3(c), 11.3 and 11.4), ratably in accordance with the sum of the applicable Lenders' respective Commitments, for any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind 81

and nature whatsoever, REGARDLESS OF WHETHER CAUSED IN WHOLE OR IN PART BY THE NEGLIGENCE OF ANY INDEMNIFIED PARTIES, which may be imposed on, incurred by or asserted against the applicable Administrative Agent in any way relating to or arising out of this Agreement, the Letters of Credit or any other Loan Document or any other documents contemplated by or referred to herein or therein or the transactions contemplated hereby or thereby (including, without limitation, the costs and expenses which any Borrower is obligated to pay under Sections 2.3(c), 11.3 and 11.4 hereof, interest, penalties, attorneys' fees and amounts paid in settlement, but excluding, unless a Default has occurred and is continuing, normal administrative costs and expenses incident to the performance of its agency duties hereunder) or the enforcement of any of the terms hereof or thereof or of any such other documents; provided that no Lender shall be liable for any of the foregoing to the extent they arise from the gross negligence or willful misconduct of the party to be indemnified. The obligations of the Lenders under this Section 10.6 shall survive the termination of this Agreement and the repayment of the Obligations. NON-RELIANCE ON ADMINISTRATIVE AGENTS AND OTHER LENDERS. Each Lender agrees that it has received current financial information with respect to each Borrower and each other Obligor and that it has, independently and without reliance on any Administrative Agent or any other Lender and based on such documents and information as it has deemed appropriate, made its own credit analysis of each Borrower and each other Obligor and decision to enter into this Agreement and that it will, independently and without reliance upon any Administrative 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 analysis and decisions in taking or not taking action under this Agreement or any of the other Loan Documents. None of the Administrative Agents shall be required to keep itself informed as to the performance or observance by any Obligor of this Agreement, the Letters of Credit or any of the other Loan Documents or any other document referred to or provided for herein or therein or to inspect the properties or books of any Obligor. Except for notices, reports and other documents and information expressly required to be furnished to an Administrative Agent hereunder, under the Letters of Credit or the other Loan Documents, none of the Administrative Agents shall have any duty or responsibility to provide any Lender with any credit or other information concerning the affairs, financial condition or business of any Obligor (or any of their affiliates) which may come into the possession of any Administrative Agent. FAILURE TO ACT. Except for action expressly required of an Administrative Agent hereunder, under the Letters of Credit or under the other Loan Documents, each Administrative Agent shall in all cases be fully justified in failing or refusing to act hereunder and thereunder unless it shall receive further assurances to its satisfaction by the Lenders of their indemnification obligations under Section 10.6 hereof against any and all liability and expense which may be incurred by it by reason of taking or continuing to take any such action. RESIGNATION OR REMOVAL OF ADMINISTRATIVE AGENT. Subject to the appointment and acceptance of a successor U.S. Administrative Agent, Canadian Administrative Agent or Norwegian Administrative Agent, as the case may be, as provided below, U.S. Administrative Agent, Canadian Administrative Agent and Norwegian Administrative Agent, respectively, may resign at any time by giving notice thereof to the U.S. Lenders, the Canadian Lenders and 82

Norwegian Lenders, respectively, and to U.S. Borrower, Canadian Borrowers and Norwegian Borrower, respectively, and any Administrative Agent may be removed at any time with or without cause by the Majority Lenders; provided, that such Administrative Agent shall continue as U.S. Administrative Agent, Canadian Administrative Agent or Norwegian Administrative Agent, as the case may be, until such time as any successor shall have accepted appointment hereunder as U.S. Administrative Agent, Canadian Administrative Agent or Norwegian Administrative Agent, as the case may be. Upon any such resignation or removal, (i) the Majority Lenders with the consent of Borrowers (if no Event of Default shall exist and be continuing) shall have the right to appoint a successor U.S. Administrative Agent, Canadian Administrative Agent or Norwegian Administrative Agent, as the case may be, so long as such successor U.S. Administrative Agent, Canadian Administrative Agent or Norwegian Administrative Agent, as the case may be, is also a Lender at the time of such appointment and (ii) the Majority Lenders shall have the right to appoint a successor U.S. Administrative Agent, Canadian Administrative Agent or Norwegian Administrative Agent, as the case may be, that is not a Lender at the time of such appointment so long as Borrowers consent to such appointment (which consent shall not be unreasonably withheld and shall not be required if an Event of Default exists). If no successor U.S. Administrative Agent, Canadian Administrative Agent or Norwegian Administrative Agent, as the case may be, shall have been so appointed by the Majority Lenders and accepted such appointment within 30 days after the retiring U.S. Administrative Agent's, Canadian Administrative Agent's or Norwegian Administrative Agent's, as the case may be, giving of notice of resignation or the Majority Lenders' removal of the retiring U.S. Administrative Agent, Canadian Administrative Agent or Norwegian Administrative Agent, as the case may be, then the retiring Administrative Agent may, on behalf of the applicable Lenders, appoint a successor U.S. Administrative Agent, Canadian Administrative Agent or Norwegian Administrative Agent, as the case may be, with the consent of Borrowers (if no Event of Default shall exist and be continuing), but without the consent of any Lender or any Borrower if an Event of Default has occurred and is continuing. Any successor U.S. Administrative Agent shall be a bank which has an office in the United States and a combined capital and surplus of at least US$250,000,000 and any successor Canadian Administrative Agent shall be a bank which has an office in Canada and a combined capital and surplus of at least C$250,000,000 and any successor Norwegian Agent shall be a bank which has an office in Norway and a combined capital and surplus of at least NOK250,000,000 Upon the acceptance of any appointment as U.S. Administrative Agent, Canadian Administrative Agent or Norwegian Administrative Agent, as the case may be, hereunder by a successor Administrative Agent, such successor Administrative Agent shall thereupon succeed to and become vested with all the rights, powers, privileges and duties of the retiring Administrative Agent and the retiring Administrative Agent shall be discharged from its duties and obligations hereunder and under any other Loan Documents. Such successor Administrative Agent shall promptly specify by notice to Borrowers and Lenders its Principal Office referred to in Section 3.1 and Article 4 hereof. After any retiring Administrative Agent's resignation or removal hereunder as an Administrative Agent, the provisions of this Section 10 shall continue in effect for its benefit in respect of any actions taken or omitted to be taken by it while it was acting as Administrative Agent. 83

NO PARTNERSHIP. Neither the execution and delivery of this Agreement nor any of the other Loan Documents nor any interest the Lenders, Administrative Agents or any of them may now or hereafter have in all or any part of the Obligations shall create or be construed as creating a partnership, joint venture or other joint enterprise between the Lenders or among the Lenders and any Administrative Agent. The relationship between the Lenders, on the one hand, and any Administrative Agent, on the other, is and shall be that of principals and Administrative Agent only, and nothing in this Agreement or any of the other Loan Documents shall be construed to constitute any Administrative Agent as trustee or other fiduciary for any Lender or to impose on any Administrative Agent any duty, responsibility or obligation other than those expressly provided for herein and therein. MISCELLANEOUS WAIVER. No waiver of any Default or Event of Default shall be a waiver of any other Default or Event of Default. No failure on the part of any Administrative Agent or any Lender to exercise and no delay in exercising, and no course of dealing with respect to, any right, power or privilege under any Loan Document shall operate as a waiver thereof, nor shall any single or partial exercise of any right, power or privilege thereunder preclude any other or further exercise thereof or the exercise of any other right, power or privilege. The remedies provided in the Loan Documents are cumulative and not exclusive of any remedies provided by law or in equity. NOTICES. All notices and other communications provided for herein (including, without limitation, any modifications of, or waivers or consents under, this Agreement) shall be given or made by telex, telegraph, telecopy (confirmed by mail), cable, electronic mail (pursuant to procedures approved in writing by U.S. Administrative Agent, provided that approval of such procedures may be limited to particular notices or communications) or other writing and telexed, telecopied, telegraphed, cabled, mailed, electronically mailed or delivered to the intended recipient at the "Address for Notices" specified below its name on the signature pages hereof (or provided for in an Assignment and Acceptance); or in the case of electronic mail, in accordance with the procedures set by the U.S. Administrative Agent, or, as to any party hereto, at such other address as shall be designated by such party in a notice (given in accordance with this Section) (i) as to any Borrower, to Administrative Agents, (ii) as to U.S. Administrative Agent, to U.S. Borrower and to each U.S. Lender, (iii) as to Canadian Administrative Agent, to a Canadian Borrower and to each Canadian Lender, (iv) as to Norwegian Administrative Agent, to Norwegian Borrower and to each Norwegian Lender, (v) as to any U.S. Lender, to U.S. Borrower and Administrative Agents, (v) as to any Canadian Lender, to a Canadian Borrower and Administrative Agents and (vi) as to any Norwegian Lender, to Norwegian Borrower and Administrative Agents.

INDEMNIFICATION. Each Borrower, shall indemnify each applicable Administrative Agent and each applicable Lender and each affiliate thereof and their respective directors, officers and employees from, and hold each of them harmless against, any and all losses, liabilities, claims or damages to which any of them may become subject, REGARDLESS OF WHETHER CAUSED IN WHOLE OR IN PART BY THE NEGLIGENCE OF ANY INDEMNIFIED PARTIES, insofar as such losses, liabilities, claims or damages arise out of or result from any (i) actual or proposed use by any such Borrower of the proceeds of any extension of credit (whether a Loan, a Bankers' Acceptance or a Letter of Credit) by any Lender hereunder; (ii) breach by any Obligor of this Agreement or any other Loan Document; (iii) violation by any 85

Obligor of any Legal Requirement, or (iv) investigation, litigation or other proceeding relating to any of the foregoing, and each Borrower, shall reimburse each applicable Administrative Agent, each applicable Lender, and each Affiliate thereof and their respective directors, officers and employees, upon demand for any reasonable expenses (including reasonable legal fees) incurred in connection with any such investigation or proceeding; provided, however, that none of the Borrowers shall have any obligations pursuant to this Section with respect to any losses, liabilities, claims, damages or expenses incurred by the Person seeking indemnification by reason of the gross negligence or willful misconduct of that Person or with respect to any disputes between or among any or all of Administrative Agents, Lenders, U.S. Swing Line Lender and Issuers. Nothing in this Section is intended to limit the obligations of any Borrower under any other provision of this Agreement. Each Administrative Agent, each Lender and the U.S. Swing Line Lender, respectively, shall indemnify Borrowers and hold Borrowers harmless from and against the gross negligence or willful misconduct of such Administrative Agent, such Lender or such U.S. Swing Line Lender, as the case may be. Nothing in this Section shall render a Canadian Borrower liable in respect of the U.S. Obligations or Norwegian Obligations.

Nothing in this Section shall render U.S. Borrower liable in respect of the Canadian Obligations or the Norwegian Obligations. AMENDMENTS, ETC. No amendment or modification of this Agreement, the Notes or any other Loan Document shall in any event be effective against any Borrower unless the same shall be agreed or consented to in writing by the applicable Borrower. No amendment, modification or waiver of any provision of this Agreement, the Notes or any other Loan Document, nor any consent to any departure by any Borrower therefrom, shall in any event be effective against the Lenders unless the same shall be agreed or consented to in writing by the Majority Lenders, and each such waiver or consent shall be effective only in the specific instance and for the specific purpose for which given; provided, that no amendment, modification, waiver or consent shall, unless in writing and signed by each Lender affected thereby, do any of the following: (a) increase any Commitment of any of the Lenders (or reinstate any termination or reduction of the Commitments) or subject any of the Lenders to any additional obligations; (b) reduce the principal of, or interest on, any Loan, Reimbursement Obligation, fee or other amount due hereunder; (c) postpone or extend the Maturity Date, the Termination Date, the Availability Period or any scheduled date fixed for any payment of principal of, or interest on, any Loan, Reimbursement Obligation, fee or other sum to be paid hereunder or waive any Event of Default described in Section 9.1(a) hereof; (d) change the percentage of any of the Commitments or of the aggregate unpaid principal amount of Obligations, or the percentage of Lenders, which shall be required for the Lenders or any of them to take any action under this Agreement; (e) change any provision contained in Sections 2.3(c), 7.8, 11.3 or 11.4 hereof or this Section 11.5, or (f) release any Person from liability under a Guaranty or release all or substantially all of the security, if any, for the Obligations or release collateral, if applicable (exclusive of collateral, if any, with respect to which any Administrative Agent is obligated to provide a release pursuant to this Agreement or any of the other Loan Documents or by law) in any one (1) calendar year ascribed an aggregate value on the most recent financial statements of the applicable Borrower delivered to Administrative Agents in excess of US$1,000,000. Notwithstanding 86

SUCCESSORS AND ASSIGNS. This Agreement shall be binding upon and inure to the benefit of Borrowers, Administrative Agents and the Lenders and their respective successors and assigns; provided, however, that no Borrower may assign or transfer any of its rights or obligations hereunder without the prior written consent of all of the Lenders, and any such assignment or transfer without such consent shall be null and void. Each Lender may sell participations to any Person in all or part of any Loan or Bankers' Acceptance, or all or part of its Notes, Commitments or interests in Letters of Credit or Bankers' Acceptances, in which event, without limiting the foregoing, the provisions of the Loan Documents shall inure to the benefit of each purchaser of a participation; provided, however, the pro rata treatment of payments, as described in Section 4.2 hereof, shall be determined as if such Lender had not sold such participation. No Lender that sells one or more participations to any Person shall be relieved by virtue of such participation from any of its obligations to Borrowers under this Agreement. In the event any Lender shall sell any participation, such Lender shall retain the sole right and responsibility to enforce the obligations of Borrowers hereunder, including, without limitation, the right to approve any amendment, modification or waiver of any provision of this Agreement other than amendments, modifications or waivers with respect to (i) any fees payable hereunder to the Lenders, (ii) the amount of principal or the rate of interest payable on, or the dates fixed for the scheduled repayment of principal of, any of the Obligations and (iii) the release of the Liens on all or substantially all of the collateral, if applicable. Each U.S. Lender may assign to one or more U.S. Lenders or any other Person all or a portion of its interests, rights and obligations under this Agreement; provided, however, that (i) the aggregate amount of the Commitments of the assigning U.S. Lender subject to each such assignment shall in no event be less than US$5,000,000 and (ii) other than in the case of an assignment to another U.S. Lender (that is, at the time of the assignment, a party hereto) or to an Affiliate of such U.S. Lender or to a Federal Reserve Bank, the U.S. Administrative Agent and, so long as no Event of Default shall have occurred and be continuing, U.S. Borrower must both provide prior written consent, which consent shall not be unreasonably withheld. Each Canadian Lender may assign to one or more Canadian Lenders or any other Person all or a portion of its interests, rights and obligations under this Agreement; provided, however, that (i) the aggregate amount of the Commitments of the assigning Canadian Lender subject to each such assignment shall in no event be less than C$5,000,000 and (ii) other than in the case of an assignment to another Canadian Lender (that is, at the time of the assignment, a party hereto) or to an Affiliate of such Canadian Lender, the Canadian Administrative Agent and, so long as no Event of Default shall have occurred and be continuing, each Canadian Borrower must provide prior written consent, which consent shall not be unreasonably withheld. Norwegian Lender may assign to one or more Norwegian 87

Lenders or any other Person all or a portion of its interests, rights and obligations under this Agreement; provided, however, that (i) the aggregate amount of the Commitments of the assigning Norwegian Lender subject to each such assignment shall in no event be less than NOK50,000,000 and (ii) other than in the case of an assignment to another Norwegian Lender (that is, at the time of the assignment, a party hereto) or to an Affiliate of such Norwegian Lender, the Norwegian Administrative Agent and, so long as no Event of Default shall have occurred and be continuing, Norwegian Borrower must provide prior written consent, which consent shall not be unreasonably withheld. As a condition precedent to any such assignment, the parties to each such assignment shall execute and deliver to the applicable Administrative Agent, for its acceptance an Assignment and Acceptance in the form of Exhibit G hereto (each an "Assignment and Acceptance") with blanks appropriately completed, together with any Note or Notes subject to such assignment and a processing and recording fee of US$5,000 paid by the assignee for the benefit of the applicable Administrative Agent (for which Borrowers will have no liability). Upon such execution, delivery and acceptance, from and after the effective date specified in each Assignment and Acceptance, (A) the assignee thereunder shall be a party hereto and, to the extent provided in such Assignment and Acceptance, have the rights and obligations of a Lender hereunder and (B) the Lender thereunder shall, to the extent provided in such Assignment and Acceptance, be released from its obligations under this Agreement (and, in the case of an Assignment and Acceptance covering all or the remaining portion of an assigning Lender's rights and obligations under this Agreement, such Lender shall cease to be a party hereto except in respect of provisions of this Agreement which survive payment of the Obligations and termination of the Commitments). Notwithstanding anything contained in this Agreement to the contrary, any Lender may at any time assign all or any portion of its rights under this Agreement and the other Loan Documents as collateral to a Federal Reserve Bank; provided that no such assignment shall release such Lender from any of its obligations hereunder. By executing and delivering an Assignment and Acceptance, the assignor and assignee thereunder confirm to and agree with each other and the other parties hereto as follows: (i) other than the representation and warranty that it is the legal and beneficial owner of the interest being assigned thereby free and clear of any adverse claim, the applicable assignor makes no representation or warranty and assumes no responsibility with respect to any statements, warranties or representations made in or in connection with this Agreement or any of the other Loan Documents or the execution, legality, validity, enforceability, genuineness, sufficiency or value of this Agreement or any of the other Loan Documents or any other instrument or document furnished pursuant thereto; (ii) the applicable assignor makes no representation or warranty and assumes no responsibility with respect to the financial condition of any Borrower or the performance or observance by any Borrower of any of its obligations under this Agreement or any of the other Loan Documents or any other instrument or document furnished pursuant hereto; (iii) the applicable assignee confirms that it has received a copy of this Agreement, together with copies of the financial statements referred to in Section 6.2 hereof and such other documents and information as it has deemed appropriate to make its own credit analysis and decision to enter into such Assignment and Acceptance; (iv) the applicable assignee will, independently and without reliance upon any Administrative Agent, the applicable assignor or any other Lender and based on such 88

documents and information as it shall deem appropriate at the time, continue to make its own credit decisions in taking or not taking action under this Agreement and the other Loan Documents; (v) the applicable assignee appoints and authorizes U.S. Administrative Agent, Canadian Administrative Agent or Norwegian Administrative Agent, as the case may be, to take such action as Administrative Agent on its behalf and to exercise such powers under this Agreement and the other Loan Documents as are delegated to such Administrative Agent by the terms hereof, together with such powers as are reasonably incidental thereto; and (vi) the applicable assignee agrees that it will perform in accordance with their terms all obligations that by the terms of this Agreement and the other Loan Documents are required to be performed by it as a Lender. The entries in the records of each applicable Administrative Agent as to each Assignment and Acceptance delivered to it and the names and addresses of the Lenders and the Commitments of, and principal amount of the Obligations owing to, each Lender from time to time shall be conclusive, in the absence of manifest error, and Borrowers, Administrative Agents and the Lenders may treat each Person the name of which is recorded in the books and records of the applicable Administrative Agent as a Lender hereunder for all purposes of this Agreement and the other Loan Documents. Upon the applicable Administrative Agent's receipt of an Assignment and Acceptance executed by an assigning Lender and the assignee thereunder, together with any Note or Notes subject to such assignment and the written consent to such assignment (to the extent consent is required), such Administrative Agent shall, if such Assignment and Acceptance has been completed with blanks appropriately filled, (i) accept such Assignment and Acceptance, (ii) record the information contained therein in its records and (iii) give prompt notice thereof to the applicable Borrower. Within five Business Days after receipt of notice, the applicable Borrower, at its own expense, shall execute and deliver to the applicable Administrative Agent in exchange for the old Notes, new Notes payable to the order of such assignee in the appropriate amounts and, if the assigning Lender has retained Commitments hereunder, new Notes to the order of the assigning Lender in the appropriate amounts. Such new Notes shall be dated the effective date of such Assignment and Acceptance and shall otherwise be in the forms required hereunder. Any Lender may, in connection with any assignment or participation or proposed assignment or participation pursuant to this Section 11.6, disclose to the assignee or participant or proposed assignee or participant, any information relating to any Borrower furnished to such Lender by or on behalf of any Borrower, subject to Section 11.18. LIMITATION OF INTEREST. Borrowers and the Lenders intend to strictly comply with all applicable laws, including applicable usury laws (or the usury laws of any jurisdiction, including Canada and Norway, whose usury laws are deemed to apply to the Notes or any other Loan Documents. Accordingly, the provisions of this Section 11.7 shall govern and control over every other provision of this Agreement or any other Loan Document which conflicts or is inconsistent with this Section, even if such provision declares that it controls. As used in this Section, the term "interest" includes the aggregate of all charges, fees, benefits or other compensation which constitutes interest under applicable law, provided that, to the maximum extent permitted by applicable law, (a) any non-principal payment shall be 89

characterized as an expense or as compensation for something other than the use, forbearance or detention of money and not as interest, and (b) all interest at any time contracted for, reserved, charged or received shall be amortized, prorated, allocated and spread, in equal parts during the full term of the Obligations. In no event shall Borrowers or any other Person be obligated to pay, or any Lender have any right or privilege to reserve, receive or retain, (a) any interest in excess of the maximum amount of nonusurious interest permitted under the applicable laws (if any) of the United States or of any other applicable jurisdiction, or (b) total interest in excess of the amount which such Lender could lawfully have contracted for, reserved, received, retained or charged had the interest been calculated for the full term of the Obligations at the Ceiling Rate. The daily interest rates to be used in calculating interest at the Ceiling Rate shall be determined to the extent provided by applicable law by dividing the applicable Ceiling Rate per annum by the number of days in the calendar year for which such calculation is being made. None of the terms and provisions contained in this Agreement or in any other Loan Document (including, without limitation, Section 9.1 hereof) which directly or indirectly relate to interest shall ever be construed without reference to this Section 11.7, or be construed to create a contract to pay for the use, forbearance or detention of money at an interest rate in excess of the Ceiling Rate. If the term of any Obligation is shortened by reason of acceleration of maturity as a result of any Default or by any other cause, or by reason of any required or permitted prepayment, and if for that (or any other) reason any Lender at any time, including but not limited to, the stated maturity, is owed or receives (and/or has received) interest in excess of interest calculated at the Ceiling Rate, then and in any such event all of any such excess interest shall be canceled automatically as of the date of such acceleration, prepayment or other event which produces the excess, and, if such excess interest has been paid to such Lender, it shall be credited pro tanto against the then-outstanding principal balance of the applicable Borrower's obligations to such Lender, effective as of the date or dates when the event occurs which causes it to be excess interest, until such excess is exhausted or all of such principal has been fully paid and satisfied, whichever occurs first, and any remaining balance of such excess shall be promptly refunded to its payor. SURVIVAL. The obligations of Borrowers under Sections 2.3(c), 2.3(d), 7.8, 11.3 and 11.4 hereof and all other obligations of Borrowers in any other Loan Document (to the extent stated therein), the obligations of each Issuer under the last sentence of Section 2.3(b)(iii) and the obligations of the Lenders under Section 10.5 and 11.7 hereof, shall, notwithstanding anything herein to the contrary, survive the repayment of the Loans and Reimbursement Obligations and the termination of the Commitments and the Letters of Credit. CAPTIONS. Captions and section headings appearing herein are included solely for convenience of reference and are not intended to affect the interpretation of any provision of this Agreement. COUNTERPARTS. This Agreement may be executed in any number of counterparts, all of which taken together shall constitute one and the same agreement and any of the parties hereto may execute this Agreement by signing any such counterpart. VENUE; GOVERNING LAW. This Agreement and (except as therein provided) the other Loan Documents are performable in Harris County, Texas, which shall be a proper place of venue for suit on or in respect thereof. Each Borrower irrevocably agrees that any legal proceeding 90

in respect of this Agreement or the other Loan Documents shall be brought in the district courts of Harris County, Texas or the United States District Court for the Southern District of Texas, Houston Division (collectively, the "Specified Courts"). Each Borrower hereby irrevocably submits to the nonexclusive jurisdiction of the state and federal courts of the State of Texas. Each Borrower hereby irrevocably waives, to the fullest extent permitted by law, any objection which it may now or hereafter have to the laying of venue of any suit, action or proceeding arising out of or relating to any Loan Document brought in any Specified Court, and hereby further irrevocably waives any claims that any such suit, action or proceeding brought in any such court has been brought in an inconvenient forum. Each Borrower further (1) agrees to designate and maintain an agent for service of process in the State of Texas in connection with any such suit, action or proceeding upon request by any Administrative Agent and to deliver to Administrative Agents evidence thereof and (2) irrevocably consents to the service of process out of any of the aforementioned courts in any such suit, action or proceeding by the mailing of copies thereof by certified mail, return receipt requested, postage prepaid, to such Borrower at its address as provided in this Agreement or as otherwise provided by applicable law. Nothing herein shall affect the right of any Administrative Agent or any applicable Lender to commence legal proceedings or otherwise proceed against any Borrower in any jurisdiction or to serve process in any manner permitted by applicable law. Each Borrower agrees that a final judgment in any such action or proceeding shall be conclusive to the extent allowed by any applicable treaties under U.S., Canadian or Norwegian laws, as the case may be, and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by law. THIS AGREEMENT AND (EXCEPT AS THEREIN PROVIDED) THE OTHER LOAN DOCUMENTS SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE APPLICABLE LAWS OF THE STATE OF TEXAS AND THE UNITED STATES OF AMERICA (IT BEING EXPRESSLY UNDERSTOOD AND AGREED THAT EACH LENDER SHALL BE ENTITLED TO THE BENEFITS OF ITS APPLICABLE FEDERAL LAW OF THE UNITED STATES OF AMERICA AND ITS OTHER APPLICABLE LAW WITH RESPECT TO USURY LAWS) FROM TIME TO TIME IN EFFECT; PROVIDED, HOWEVER, THAT, EXCEPT AS MAY BE REQUIRED UNDER APPLICABLE LAWS, THE USURY LAWS OF THE STATE OF TEXAS OR THE UNITED STATES OF AMERICA SHALL NOT APPLY TO ADVANCES MADE IN CANADA BY CANADIAN LENDERS TO CANADIAN BORROWER, BUT RATHER THE USURY LAWS OF THE PROVINCE OF ALBERTA AND THE FEDERAL LAWS OF CANADA APPLICABLE THEREIN SHALL GOVERN IN SUCH CONTEXT AND THE USURY LAWS OF THE STATE OF TEXAS OR THE UNITED STATES OF AMERICA SHALL NOT APPLY TO ADVANCES MADE IN NORWAY BY NORWEGIAN LENDERS TO NORWEGIAN BORROWER, BUT RATHER THE USURY LAWS OF NORWAY APPLICABLE THEREIN SHALL GOVERN IN SUCH CONTEXT. SEVERABILITY. Whenever possible, each provision of the Loan Documents shall be interpreted in such manner as to be effective and valid under applicable law. If any provision of any Loan Document shall be invalid, illegal or unenforceable in any respect under any applicable law, the validity, legality and enforceability of the remaining provisions of such Loan Document shall not be affected or impaired thereby. 91

INTEREST ACT (CANADA). Whenever interest is calculated on the basis of a year of 360 or 365 days, for the purposes of the Interest Act (Canada), the yearly rate of interest which is equivalent to the rate payable hereunder is the rate payable multiplied by the actual number of days in the year and divided by 360 or 365, as the case may be. All interest will be calculated using the nominal rate method and not the effective rate method and the deemed reinvestment principle shall not apply to such calculations. JUDGMENT CURRENCY. The obligation of each Borrower to make payments on any Obligation to the Lenders or to any Administrative Agent hereunder in any currency (the "first currency") shall not be discharged or satisfied by any tender or recovery pursuant to any judgment expressed in or converted into any other currency (the "second currency") except to the extent to which such tender or recovery shall result in the effective receipt by the applicable Lender or the applicable Administrative Agent of the full amount of the first currency payable, and accordingly the primary obligation of each Borrower shall be enforceable as an alternative or additional cause of action for the purpose of recovery in the second currency of the amount (if any) by which such effective receipt shall fall short of the full amount of the first currency payable and shall not be affected by a judgment being obtained for any other sum due hereunder. CONFLICTS BETWEEN THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS. In the event of any conflict between the terms of this Agreement and the terms of any of the other Loan Documents, the terms of this Agreement shall control. LIMITATION ON CHARGES; SUBSTITUTE LENDERS; NON-DISCRIMINATION. Anything herein notwithstanding: No Borrower shall be required to pay to any Lender reimbursement with regard to any taxes, costs or expenses described herein, unless such Lender notifies the applicable Borrower of such taxes, costs or expenses within 90 days after the date paid or incurred; none of the Lenders shall be permitted to pass through to any Borrower taxes, charges and costs described herein on a discriminatory basis (i.e., which are not also passed through by such Lender to other customers of such Lender similarly situated where such customer is subject to documents providing for such pass through); and if any Lender elects to pass through to any Borrower any material taxes, charge or cost described herein or elects to terminate the availability of LIBOR Borrowings for any material period of time, the applicable Borrower may, within 60 days after the date of such event and so long as no Default shall have occurred and be continuing, elect to terminate such Lender as a party to this Agreement; provided that, concurrently with such termination such Borrower shall (i) if Administrative Agents and each of the other Lenders shall consent, pay that Lender all principal, interest and fees and other amounts owed to such Lender through such date of termination (and concurrently herewith such Lender shall be released from all obligations with respect to Letter of Credit Liabilities and U.S. Swing Line Loans) or (ii) have arranged for another financial institution approved by Administrative Agents (such approval not to be unreasonably withheld) as of such date, to become a substitute Lender for all purposes under this Agreement in the manner provided in Section 11.6 (subject to the payment of all amounts due to the Lender being terminated); provided further that, prior to substitution for any Lender, the applicable Borrower shall have given written notice to Administrative Agents of such intention and the Lenders shall 92

have the option, but no obligation, for a period of 60 days after receipt of such notice, to increase their Commitments in order to replace the affected Lender in lieu of such substitution. MULTIPLE PERSONS COMPRISING CANADIAN BORROWER. The parties recognize and acknowledge that "Canadian Borrower" is comprised of more than one Person. All duties and obligations imposed on "Canadian Borrowers" hereunder or under any of the other Loan Documents shall be the joint and several duties and obligations of each Person comprising "Canadian Borrower", notwithstanding the manner in which any of such obligations shall be allocated among the Persons comprising "Canadian Borrowers" for the purposes of such Persons' internal records and accounts. Whenever this Agreement or any of the other Loan Documents requires the execution and delivery of any document or instrument by "Canadian Borrowers", such requirement may be satisfied by execution and delivery by any single one of the Persons comprising the applicable "Canadian Borrowers", and execution and delivery of any document or instrument by any single one of the Persons comprising "Canadian Borrowers" shall be binding upon each of the Persons comprising "Canadian Borrowers". CONFIDENTIALITY. Each of the Administrative Agents and the Lenders agrees to maintain the confidentiality of the Information (as defined below), except that Information may be disclosed (a) to its and its Affiliates' directors, officers, employees and agents, including accountants, legal counsel and other advisors (it being understood that the Persons to whom such disclosure is made will be informed of the confidential nature of such Information and instructed to keep such Information confidential); (b) to the extent requested by any regulatory authority; (c) to the extent required by applicable laws or regulations or by any subpoena or similar legal process; (d) to any other party to this Agreement; (e) in connection with the exercise of any remedies hereunder or any suit, action or proceeding relating to this Agreement or the enforcement of rights hereunder; (f) subject to an agreement containing provisions substantially the same as those of this Section, to any assignee of or purchaser of a participation pursuant to Section 11.6 hereof, any direct or indirect contractual counterparty or prospective counterparty (or such contractual counterparty's or prospective counterparty's professional advisor) to any credit derivative transaction relating to obligations of the Obligors; (g) with the consent of the Parent; (h) to the extent such Information (i) becomes publicly available other than as a result of a breach of this Section or (ii) becomes available to the Administrative Agent or any Lender on a nonconfidential basis from a source other than the Parent or its Subsidiaries. In addition, the Administrative Agents and the Lenders may disclose the existence of this Agreement and information about this Agreement to market data collectors, similar service providers to the lending industry, and service providers to the Administrative Agents and the Lenders in connection with the administration and management of this Agreement and the other Loan Documents. For the purposes of this Section, "Information" means all information received from any Obligor relating to such Obligor or its business, other than any such information that is available to any Administrative Agent or any Lender on a nonconfidential basis prior to disclosure by any Obligor; provided that, in the case of information received from a Loan Party after the date hereof, such information is clearly identified in writing at the time of delivery as confidential. Any Person required to maintain the confidentiality of Information as provided in this Section shall be considered to have complied with its obligation to do so if such Person 93

has exercised the same degree of care to maintain the confidentiality of such Information as such Person would accord to its own confidential information. WAIVER OF RIGHT TO TRIAL BY JURY. EACH PARTY TO THIS AGREEMENT HEREBY EXPRESSLY WAIVES ANY RIGHT TO TRIAL BY JURY OF ANY CLAIM, DEMAND, ACTION OR CAUSE OF ACTION ARISING UNDER ANY LOAN DOCUMENT OR IN ANY WAY CONNECTED WITH OR RELATED OR INCIDENTAL TO THE DEALINGS OF THE PARTIES HERETO OR ANY OF THEM WITH RESPECT TO ANY LOAN DOCUMENT, OR THE TRANSACTIONS RELATED THERETO, IN EACH CASE WHETHER NOW EXISTING OR HEREAFTER ARISING, AND WHETHER FOUNDED IN CONTRACT OR TORT OR OTHERWISE; AND EACH PARTY HEREBY AGREES AND CONSENTS THAT ANY SUCH CLAIM, DEMAND, ACTION OR CAUSE OF ACTION SHALL BE DECIDED BY COURT TRIAL WITHOUT A JURY, AND THAT ANY PARTY TO THIS AGREEMENT MAY FILE AN ORIGINAL COUNTERPART OR A COPY OF THIS SECTION WITH ANY COURT AS WRITTEN EVIDENCE OF THE CONSENT OF THE SIGNATORIES HERETO TO THE WAIVER OF THEIR RIGHT TO TRIAL BY JURY.
