Item 1.01. Entry into a Material Definitive Agreement.

Credit Agreement

     On April 21, 2008, National Oilwell Varco, Inc., a Delaware corporation (the “Company” or “National Oilwell Varco”), entered into (i) a credit agreement evidencing a five-year unsecured revolving credit facility (the “Five-Year Credit Agreement”) and (ii) a credit agreement evidencing an unsecured 364-day revolving credit facility (the “364-Day Credit Agreement”) with Wells Fargo Bank, N.A., as administrative agent, the other agents named therein, and the lenders parties thereto (collectively referred to as the “2008 Facility”), pursuant to which the Company may borrow an aggregate principal amount of up to $3.0 billion. The 2008 Facility has been utilized to fund a portion of the cash consideration payable by the Company in its acquisition of Grant Prideco, Inc., a Delaware corporation (“Grant Prideco”). The 2008 Facility will also be utilized for general corporate purposes. Borrowings under the 2008 Facility bear interest at the rates specified in the agreements, and the agreements contain customary covenants, including leverage ratio covenants. The Company has the right to increase the aggregate commitments under the 2008 Facility to an aggregate amount of up to $4 billion.

     The foregoing description of the 2008 Facility does not purport to be complete and is qualified in its entirety by reference to the full text of the Five-Year Credit Agreement and the 364-Day Credit Agreement, which are filed as Exhibits 10.1 and 10.2, respectively, to this Form 8-K and incorporated by reference herein.

Indenture

     In connection with the Company’s acquisition of Grant Prideco, the Company consummated the settlement of its exchange offer (the “Exchange Offer”) to exchange up to $174,585,000 in aggregate principal amount of all properly tendered and accepted 6 1/8% Senior Notes due 2015 issued by Grant Prideco (the “Grant Prideco Notes”) for up to $174,585,000 in aggregate principal amount of 6 1/8% Senior Notes due 2015 issued by the Company (the “Company Notes”).

     As of the expiration deadline for the Exchange Offer of 9:00 a.m., New York City time, on April 21, 2008, $150,816,000 in aggregate principal amount of 6 1/8% Senior Notes due 2015 issued by Grant Prideco, representing approximately 86% of the outstanding Grant Prideco Notes, had been validly tendered (and not withdrawn) in the Exchange Offer. In connection with the consummation of the Exchange Offer, the Company accepted such tendered notes and issued $150,816,000 in aggregate principal amount of Company Notes.

     The Company Notes are unsecured obligations and were issued in connection with the Exchange Offer pursuant to an indenture dated as of April 21, 2008 between the Company and The Bank of New York Trust Company, N.A., a national banking association, as trustee (the “Company Indenture”). Under the Company Indenture, the Company Notes bear interest at the annual rate of 6 1/8%, payable semi-annually in arrears on February 15 and August 15 of each

2

year, and will mature on August 15, 2015, unless sooner redeemed. Interest accrues on the Company Notes from February 15, 2008, the most recent date to which interest has been paid on the Grant Prideco Notes. Interest payments will commence on August 15, 2008.

     The foregoing description of the Company Indenture does not purport to be complete and is qualified in its entirety by reference to the full text of the Company Indenture, which is filed hereto as Exhibit 4.1 and incorporated by reference herein.

     In connection with the Exchange Offer, the Company also completed a solicitation of consents (the “Consent Solicitation”) to certain proposed amendments, as described in the Company’s Prospectus dated March 20, 2008, to the indenture dated as of July 27, 2005 between Grant Prideco and Wells Fargo Bank, N.A., a national banking corporation, as trustee, as amended and supplemented from time to time (the “Grant Prideco Indenture”), which governs the Grant Prideco Notes. The Company accepted the consents of each eligible holder of Grant Prideco Notes who had validly tendered (and not validly revoked) their consent prior to 5:00 p.m., New York City time, on April 3, 2008, the consent payment deadline, and, on April 21, 2008, paid to the exchange agent the applicable consent payment of $2.50 per $1,000 principal amount of Grant Prideco Notes for the benefit of such holders of Grant Prideco Notes. The amendments to the Grant Prideco Indenture became operative upon the acceptance of the Grant Prideco Notes in the Exchange Offer. The amendments eliminate various restrictive covenants and some of the events of default. The Grant Prideco Notes remaining after the settlement of the Exchange Offer continue to be governed by the Grant Prideco Indenture.

     The foregoing description of the Grant Prideco Indenture and the amendments effected as a result of the Consent Solicitation does not purport to be complete and is qualified in its entirety by reference to the full text of the Grant Prideco Indenture. A copy of the Sixth Supplemental Indenture dated as of April 18, 2008, effecting such amendments, is filed hereto as Exhibit 4.3 to this Form 8-K and incorporated by reference herein.

Employee Benefit Agreement

     In connection with the Merger Agreement referred to in Item 2.01 of this Form 10-K , the Company entered into the Weatherford Employee Benefit Agreement dated as of April 21, 2008 with Weatherford International Ltd., a Bermuda exempted company (“Weatherford Bermuda”), Weatherford International, Inc. (together with Weatherford Bermuda and its subsidiaries, collectively, the “Weatherford Parties”), on behalf of itself and its subsidiaries, and Grant Prideco, whereby the Company agreed to assume certain obligations of Grant Prideco to issue shares of common stock to participants and former participants of three employee benefit plans of the Weatherford Parties upon the occurrence of events that cause benefits to become distributable under such plans. Such benefit plans are the Weatherford International, Inc. Executive Deferred Compensation Stock Ownership Plan, the Weatherford International, Inc. Foreign Executive Deferred Compensation Plan and the Weatherford International, Inc. Executive Deferred Compensation Plan for Non-Employee Directors. The foregoing description of the Weatherford Employee Benefit Agreement does not purport to be complete and is qualified in its entirety by reference to the full text of such agreement, which is filed as Exhibit 10.3 to this Form 8-K and incorporated by reference herein.

Item 1.02. Termination of a Material Definitive Agreement.

Termination of a Company Credit Agreement

     As a result of entering into the 2008 Facility, on April 21, 2008, the Company terminated its amended and restated credit agreement dated June 21, 2005 with a syndicate of lenders, including Wells Fargo Bank, N.A., as U.S. administrative agent. Such amended and restated agreement provided for a $500 million unsecured revolving credit facility for general corporate purposes (the “2005 Facility”). The 2005 Facility was scheduled to expire in July 2010. Borrowings under the 2005 Facility bore interest at the rates specified in the credit agreement, and the credit agreement contained leverage ratio covenants and interest coverage ratio covenants. The Company had the right to increase the aggregate commitments under the 2005 Facility to an aggregate amount of up to $750 million and to extend the term of the 2005 Facility for an additional year. There were no termination penalties incurred by the Company in connection with the termination of the 2005 Facility.

Termination of the Grant Prideco Credit Agreement

     In connection with the closing of the acquisition of Grant Prideco on April 21, 2008, as described in Item 2.01 of this Form 8-K, Grant Prideco terminated its credit agreement, dated as of May 12, 2005 and as amended to date, among Grant Prideco, as borrower, certain subsidiaries of Grant Prideco party thereto, each lender from time to time party thereto, Bank of America N.A., as syndication agent, Wells Fargo Bank, N.A., as administrative agent, and other agents named therein, as amended (the “Grant Prideco Credit Agreement”). The Grant Prideco Credit Agreement provided for aggregate borrowings of up to $350 million, including up to $25 million of U.K. borrowings. Grant Prideco had a one-time option to increase its aggregate U.S. borrowing availability under the Grant Prideco Credit Agreement by an additional $150 million. The U.S. portion of the credit facility was secured by substantially all of Grant Prideco’s and its subsidiaries’ U.S. assets, including U.S. inventories, equipment, receivables, owned real property and 65% of the stock of certain foreign subsidiaries. The U.K. portion of the credit facility was guaranteed by Grant Prideco and all U.S. subsidiaries and was secured by substantially all of Grant Prideco’s and its subsidiaries’ U.K. assets. There were no termination penalties incurred by Grant Prideco in connection with the termination of the Grant Prideco Credit Agreement.

Item 2.01 Completion of Acquisition or Disposition of Assets.

     The Company announced on April 21, 2008 the completion of its acquisition of Grant Prideco under the terms of its Agreement and Plan of Merger dated as of December 16, 2007 (the “Merger Agreement”), by and among the Company, NOV Sub, Inc., a Delaware corporation and a wholly owned subsidiary of the Company (“Merger Sub”), and Grant Prideco. With the closing of the merger transaction, each issued and outstanding share of Grant Prideco common stock was converted into the right to receive 0.4498 of a share of common stock of National Oilwell Varco and $23.20 in cash. Under the terms of the merger agreement, Grant Prideco merged with and into Merger Sub. The Company completed the merger transaction following approval of the merger by the stockholders of Grant Prideco on April 21, 2008.

     As a result of the merger transaction, the Company issued approximately 56.86 million shares of its common stock and paid approximately $2.93 billion in cash, which was funded using a combination of proceeds from the 2008 Facility and cash on hand.

     Pursuant to the terms of the merger agreement, at the effective time of the merger, each option to purchase shares of common stock of Grant Prideco, whether vested or unvested, outstanding immediately prior to the effective time of the merger was assumed by the Company and converted into an option to acquire shares of common stock of the Company. Each option so assumed and converted will continue to have, and be subject to, the same terms and conditions set forth in the governing Grant Prideco plan and any agreements thereunder immediately prior to the effective time of the merger, except that the number of shares of stock subject to such option, and the exercise price therefore, have been adjusted by an exchange ratio under the terms of the merger agreement.

     A copy of the Company’s press release dated April 21, 2008 announcing, among other things, the consummation of the merger is filed hereto as Exhibit 99.1 and incorporated by reference herein.

Item 2.03 Creation of a Direct Financial Obligation or an Obligation under an Off-Balance Sheet Arrangement of a Registrant.

     On April 21, 2008, the Company borrowed approximately $2.3 billion under the 2008 Facility, the proceeds of which were used, together with cash on hand, to pay the cash portion of the merger consideration in the Company’s acquisition of Grant Prideco, to make certain other payments in connection with the acquisition and to pay fees and expenses related to the foregoing. As of April 21, 2008, the Company had approximately $500 million available to be drawn under the 2008 Facility, the proceeds of which may be used for general corporate purposes.

     On April 21, 2008, the Company issued $150,816,000 principal amount of Company Notes under the Company Indenture.

     The information included under Item 1.01 of this Form 8-K relating to the 2008 Facility and the Company Indenture is incorporated by reference under this Item 2.03.

Item 8.01 Other Events

     On April 21, 2008, the Company announced the Company’s completion of its acquisition of Grant Prideco and the final results of the Exchange Offer. A copy of the Company’s press release is furnished as Exhibit 99.1 hereto.

Item 9.01 Financial Statements and Exhibits.

     (a) Financial Statements of Businesses Acquired

     The audited financial statements of Grant Prideco required by Item 9.01(a) of Form 8-K are incorporated herein by reference to Grant Prideco’s Annual Report on Form 10-K for the year ended December 31, 2007.

     (b) Pro Forma Financial Information

     The pro forma financial information required by Item 9.01(b) of Form 8-K is as set forth below:

5

UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL STATEMENTS

The unaudited pro forma condensed combined financial statements have been prepared assuming the merger of National Oilwell Varco and Grant Prideco is accounted for as a purchase under U.S. generally accepted accounting principles, and are based on the historical consolidated financial statements of each company which include, in the opinion of management of both companies, all adjustments necessary to present fairly the results for such periods. The unaudited pro forma condensed combined financial statements reflect the pending disposition of certain Grant Prideco tubular business units as further discussed in Note F to the Unaudited Pro Forma Condensed Combined Financial Statements. The disposition is expected to close in the first half of 2008 subject to customary closing conditions, including regulatory approval. However, there can be no assurance the pending disposition will be completed. The Pro Forma Financial Statements do not reflect cost savings that may result from the merger. The following unaudited pro forma condensed combined balance sheet as of December 31, 2007, and unaudited pro forma condensed combined statement of operations for the year ended December 31, 2007, should be read in conjunction with the historical financial statements of National Oilwell Varco and Grant Prideco and the related notes. The audited financial statements of Grant Prideco for the year ended December 31, 2007 have been incorporated by reference into this document. The unaudited pro forma condensed combined balance sheet was prepared as if the merger occurred on December 31, 2007 and the unaudited pro forma condensed income statement was prepared as if the merger occurred on January 1, 2007, in each case based on the assumptions set forth herein. Actual results associated with the merger will vary from the assumptions set forth herein.

The unaudited pro forma condensed combined financial statements are not necessarily indicative of results of operations or financial position that would have occurred had the merger been consummated earlier, nor are they necessarily indicative of future results.

National Oilwell Varco estimates that it will incur fees and expenses totaling approximately $110 million in connection with the acquisition of Grant Prideco, and it has included these costs in calculating the purchase price. National Oilwell Varco expects to incur additional charges and expenses relating to restructuring overhead functions and certain operations. The amount of these charges has not yet been determined. In addition, the pro forma information assumes a write-up in inventory to fair market value of $112.7 million. National Oilwell Varco expects that the majority of this write-up will flow out to costs of goods sold during the 12-month period following the closing date of the acquisition. The allocation of purchase price to the assets and liabilities of Grant Prideco is subject to change based on the final valuation by National Oilwell Varco’s independent third-party valuation firm.

NOTES TO UNAUDITED PRO FORMA

CONDENSED COMBINED FINANCIAL STATEMENTS

(A) To record the issuance of: (i) 56,293,781 shares of National Oilwell Varco common stock, at an assumed market price of $72.74 per share, and an assumed cash payment of $2,903.5 million to acquire all of the 125,152,915 outstanding shares of Grant Prideco common stock at December 12, 2007 at the agreed exchange ratio of 0.4498 per share plus cash paid per outstanding Grant Prideco share of $23.20 per share; and (ii) options to purchase 1,708,919 shares of National Oilwell Varco common stock at an average price of $27.19 per share, in exchange for all of the outstanding options to purchase shares of Grant Prideco common stock at an average price of $20.89 per share. This also reflects the exchange of 365,971 shares of National Oilwell Varco common stock, at an assumed market price of $72.74 per share, and cash of $18.9 million in exchange for outstanding Grant Prideco restricted stock awards. The estimated initial transaction costs of $110.0 million include one-time professional and advisory fees, and change of control costs. The following table summarizes the estimated purchase price (in millions).

	Estimated				Estimated
	Non-Cash Fair Value		Estimated		Total
	of NOV Stock and		Cash to		Purchase
	Options to be Issued		be Paid		Price
Outstanding Grant Prideco Stock	$	4,094.8	$	2,903.5	$	6,998.3

Estimated Initial Transaction Costs		—		110.0		110.0
Total Purchase Price	$	4,199.3	$	3,032.4	$	7,231.7

	Based on preliminary independent valuation estimates, the transaction is assumed to result in the write up of Grant Prideco’s inventory by $112.7 million and fixed assets by $142.1 million, the identification of additional Grant Prideco intangible assets of $3,503.8 million, the write up of other assets of $203.0 million, and related deferred taxes of $1,022.3 million. The identified intangibles include patents, customer relationships and tradenames, with lives ranging from 10 to 30 years, except for the Reed Hycalog and Grant Prideco tradenames, valued at $752.0 million, which are considered indefinite lived. The asset and liability valuations and estimated lives used to calculate the depreciation and amortization identified in (C) below are preliminary and are subject to change based on the final valuation by National Oilwell Varco’s independent valuation experts. The excess of the purchase price over the net assets acquired of $2,670.7 million is included in goodwill.
(B)	To record estimated debt issued of $1,494.4 million and related cash proceeds as a result of the transaction and to reflect cash balance required to meet working capital needs. The related interest costs on the incremental debt is $89.7 million for the year ended December 31, 2007, calculated at an estimated annual interest rate of 6.0%. The pro forma tax benefit on the additional estimated interest costs is $30.5 million for the year ended December 31, 2007, calculated at an estimated tax rate of 34%. If the pending disposition of certain Grant Prideco tubular business units were not to occur, National Oilwell Varco would expect to have an additional $535.9 million in long-term debt. This would increase pro forma interest expense by $32.2 million on a pre-tax basis and $21.2 million on an after-tax basis and would increase pro forma long-term debt from $2,408.4 million to $2,944.3 million. All of the $1,494.4 million of estimated debt issued was assumed to be issued under the 2008 Facility. National Oilwell Varco also made an exchange offer of new 61/8% Senior Notes due 2015 of National Oilwell Varco to holders of Grant Prideco’s existing $174.6 million outstanding principal amount of 61/8% Senior Notes due 2015. No additional pro forma net debt was issued by National Oilwell Varco as a result of this exchange offer.
(C)	To record the increased depreciation and amortization expense of $191.2 million for the year ended December 31, 2007, associated with the write up of fixed assets and identified intangibles, as noted in

9

	(A) above. The pro forma tax benefit on the additional depreciation and amortization costs is $65.0 million for the year ended December 31, 2007, calculated at an estimated tax rate of 34%.
(D)	To eliminate (i) revenue and costs of goods sold of $51.3 million for the year ended December 31, 2007, associated with sales between National Oilwell Varco and Grant Prideco on the Pro Forma Statement of Operations and (ii) accounts receivable and accounts payable balances of $10.4 million between National Oilwell Varco and Grant Prideco on the Pro Forma Balance Sheet at December 31, 2007.
(E)	To record additional dilution of 1,119,416 National Oilwell Varco shares related to the estimated exchange of the Grant Prideco stock options and restricted stock awards pursuant to the merger agreement.
(F)	The Grant Prideco Unaudited Pro Forma Condensed Consolidated Balance Sheet includes the historical consolidated balance sheet of Grant Prideco, adjusted to reflect the pending disposition of certain Grant Prideco tubular business units that are expected to be divested prior to the close of the merger. Atlas Bradford Premium Connections and Services, Tube-Alloy Accessories and TCA Premium Casing are being sold pursuant to an October 2007 purchase and sale agreement between Grant Prideco and Vallourec S.A. and Vallourec & Mannesmann Holdings, Inc. (collectivity referred to as “Vallourec”). In addition to the businesses being sold to Vallourec above, a tubular business located in Venezuela is being otherwise sold or discontinued by Grant Prideco. The related historical balances for all of the businesses not expected to be acquired by National Oilwell Varco have been excluded in the Grant Prideco Unaudited Pro Forma Condensed Consolidated Balance Sheet. In addition, the Grant Prideco Unaudited Pro Forma Condensed Consolidated Balance Sheet has been adjusted to reflect the sale of the three business units to Vallourec and the estimated net cash proceeds of $535.9 million (net of estimated transaction costs and income taxes) received in that disposition. The Grant Prideco Unaudited Pro Forma Condensed Consolidated Balance Sheet is based on preliminary estimates of transaction costs and net cash proceeds received that could differ following consummation of these transactions. Additionally, there can be no assurance the sales will be completed.

Following are details related to Grant Prideco’s Unaudited Pro Forma Condensed Consolidated Balance Sheet.

THE NOTES

SECTION 2.1 FORM AND DATING

     The Notes and the Trustee’s certificate of authentication shall be substantially in the form of Exhibit A hereto. The Notes may have notations, legends or endorsements required by law, stock exchange rule or usage. Each Note shall be dated the date of its authentication. The Notes shall be in denominations of $1,000 and integral multiples thereof.

     The Notes will mature on August 15, 2015, and each Note will bear interest from February 15, 2008 (which date shall be set forth in the certificate representing such Note) at the rate per annum of 6¹/₈%, which interest shall be payable semiannually on each February 15 and August 15 following the date of initial issuance of such Note, commencing on the first February 15 or August 15 next following the date of initial issuance of such Note (which date shall be set forth in the certificate representing such Note), to the Person in whose name the certificate representing such Note is registered at the close of business on the preceding February 1 or August 1 (whether or not a Business Day), as the case may be. The Notes will be subject to redemption prior to maturity pursuant to Article III of this Indenture.

     The Notes are senior unsecured obligations of the Company and rank pari passu in right of payment with all other unsecured and unsubordinated indebtedness of the Company.

     The terms and provisions contained in the Notes shall constitute, and are hereby expressly made, a part of this Indenture and the Company and the Trustee, by their execution and delivery of this Indenture, expressly agree to such terms and provisions and to be bound thereby. However, to the extent any provision of any Note conflicts with the express provisions of this Indenture, the provisions of this Indenture shall govern and be controlling. Notes issued in global form shall be substantially in the form of Exhibit A attached hereto (including the Global Note Legend and the “Schedule of Exchanges of Interests in the Global Note” attached thereto). Notes issued in definitive form shall be substantially in the form of Exhibit A attached hereto (but without the Global Note Legend and without the “Schedule of Exchanges of Interests in the Global Note” attached thereto). Each Global Note shall represent such of the outstanding Notes as shall be specified therein and each shall provide that it shall represent the aggregate principal amount of outstanding Notes from time to time endorsed thereon and that the aggregate principal amount of outstanding Notes represented thereby may from time to time be reduced or increased, as appropriate, to reflect exchanges and redemptions. Any endorsement of a Global Note to reflect the amount of any increase or decrease in the aggregate principal amount of outstanding

8

Notes represented thereby shall be made by the Trustee, the Depositary or the Note Custodian, at the direction of the Trustee, in accordance with instructions given by the Holder thereof as required by Section 2.6 hereof.

SECTION 2.2 EXECUTION AND AUTHENTICATION

     An Officer (who shall be the Chief Executive Officer, the Chief Financial Officer or the Treasurer) shall sign the Notes for the Company by manual or facsimile signature.

     If the Officer whose signature is on a Note no longer holds that office at the time a Note is authenticated, the Note shall nevertheless be valid.

     A Note shall not be valid until authenticated by the manual signature of the Trustee. The signature shall be conclusive evidence that the Note has been authenticated under this Indenture.

     The Trustee shall, upon a written order of the Company signed by an Officer (an “Authentication Order”), authenticate and make available for delivery Notes for original issue on the date hereof up to an aggregate principal amount of $174,585,000 (and any Notes subsequently issued by reopening the series of Notes as described below). The aggregate principal amount of Notes which may be authenticated and delivered under this Indenture is initially limited to $174,585,000, except for Notes authenticated and delivered upon registration of transfer of, or in exchange for, or in lieu of, other Notes pursuant to Sections 2.6, 2.7, 2.10, or 9.5; provided, however, that the Company may, so long as no Event of Default has occurred and is continuing, reopen the series of Notes represented by the 6¹/₈% Notes due 2015 to issue additional Notes for such series, which shall form a single series with the Notes and shall have the same terms, without the consent of the Holders. All Notes issued by reopening the series of Notes as provided in the previous sentence shall be identical in all respects to the Notes issued on the date hereof, other than the Issue Date, the date from which interest accrues and any changes relating thereto. Notwithstanding the provisions of Section 2.6 permitting the issuance of Definitive Notes, the Notes issued on the date hereof in the aggregate principal amount of up to $174,585,000 will be issued in the form of Global Notes only and no Holder shall have the right to receive such a Note in the form of a Definitive Note unless Definitive Notes are issued as required in Section 2.6(a).

     The Trustee may appoint an authenticating agent acceptable to the Company to authenticate Notes. An authenticating agent may authenticate Notes whenever the Trustee may do so. Each reference in this Indenture to authentication by the Trustee includes authentication by such agent. An authenticating agent has the same rights as an Agent to deal with Holders or an Affiliate of the Company.

SECTION 2.3 REGISTRAR AND PAYING AGENT

     The Company shall maintain an office or agency within the City and State of New York where Notes may be presented for registration of transfer or for exchange (“Registrar”) and an office or agency where Notes may be presented for payment (“Paying Agent”). The Registrar shall keep a register of the Notes and of their transfer and exchange. The Company may appoint one or more co-registrars and one or more additional paying agents. The term “Registrar” includes any co-registrar and the term “Paying Agent” includes any additional paying agent. The

9

Company may change any Paying Agent or Registrar without notice to any Holder. The Company shall promptly notify the Trustee in writing of the name and address of any Agent not a party to this Indenture. If the Company fails to appoint or maintain another entity as Registrar or Paying Agent, the Trustee shall act as such. The Company or any of its Subsidiaries may act as Paying Agent or Registrar.

     The Company initially appoints The Depository Trust Company (“DTC”) to act as Depositary with respect to the Global Notes.

     The Company initially appoints the Trustee to act as the Registrar and Paying Agent and to act as Note Custodian with respect to the Global Notes.

SECTION 2.4 PAYING AGENT TO HOLD MONEY IN TRUST

     The Company shall require each Paying Agent other than the Trustee to agree in writing that the Paying Agent will hold in trust for the benefit of Holders or the Trustee all money held by the Paying Agent for the payment of principal of, or interest or premium, if any, on, the Notes, and will notify the Trustee of any default by the Company in making any such payment. While any such default continues, the Trustee may require a Paying Agent to pay all money held by it to the Trustee. The Company at any time may require a Paying Agent to pay all money held by it to the Trustee. Upon payment over to the Trustee, the Paying Agent (if other than the Company or a Subsidiary) shall have no further liability for the money. If the Company or a Subsidiary acts as Paying Agent, it shall segregate and hold in a separate trust fund for the benefit of the Holders all money held by it as Paying Agent. Upon any bankruptcy or reorganization proceedings relating to the Company, the Trustee shall serve as Paying Agent for the Notes.

SECTION 2.5 HOLDER LISTS

     The Trustee shall preserve in as current a form as is reasonably practicable the most recent list available to it of the names and addresses of all Holders and shall otherwise comply with TIA Section 312(a). If the Trustee is not the Registrar, the Company shall provide to a Responsible Officer of the Trustee at least seven Business Days before each Interest Payment Date and at such other times as the Trustee may request in writing, a list in such form and as of such date as the Trustee may reasonably require of the names and addresses of the Holders of Notes and the Company shall otherwise comply with TIA Section 312(a).

SECTION 2.6 TRANSFER AND EXCHANGE

     (a) Transfer and Exchange of Global Notes. A Global Note may not be transferred as a whole except by the Depositary to a nominee of the Depositary, by a nominee of the Depositary to the Depositary or to another nominee of the Depositary, or by the Depositary or any such nominee to a successor Depositary or a nominee of such successor Depositary. All Global Notes will be exchanged by the Company for Definitive Notes if (i) the Company delivers to the Trustee notice from the Depositary that it is unwilling or unable to continue to act as Depositary for the Global Notes or that it is no longer a clearing agency registered under the Exchange Act and, in either case, a successor Depositary is not appointed by the Company within 90 days after the date of

10

such notice from the Depositary or (ii) the Company in its sole discretion notifies the Trustee in writing that it elects to cause issuance of the Notes in certificated form. Upon the occurrence of either of the preceding events in (i) or (ii) above, Definitive Notes shall be issued in such names as the Depositary shall instruct the Trustee. Global Notes also may be exchanged or replaced, in whole or in part, as provided in Sections 2.7 and 2.11 hereof. Every Note authenticated and delivered in exchange for, or in lieu of, a Global Note or any portion thereof, pursuant to Section 2.7 or 2.11 hereof, shall be authenticated and delivered in the form of, and shall be, a Global Note. A Global Note may not be exchanged for another Note other than as provided in this Section 2.6(a); however, beneficial interests in a Global Note may be transferred and exchanged as provided in Section 2.6(b), (c) or (f) hereof.

     (b) Transfer and Exchange of Beneficial Interests in the Global Notes. The transfer and exchange of beneficial interests in the Global Notes shall be effected through the Depositary, in accordance with the provisions of this Indenture and the Applicable Procedures. Transfers of beneficial interests in the Global Notes also shall require compliance with either subparagraph (i) or (ii) below, as applicable, as well as one or more of the other following subparagraphs as applicable:

     (i) Transfer of Beneficial Interests in the Same Global Note. Beneficial interests in any Global Note may be transferred only to Persons who take delivery thereof in the form of a beneficial interest in a Global Note. No written orders or instructions shall be required to be delivered to the Registrar to effect the transfers described in this Section 2.6(b)(i).

     (ii) All Other Transfers and Exchanges of Beneficial Interests in Global Notes. In connection with all transfers and exchanges of beneficial interests (other than a transfer of a beneficial interest in a Global Note to a Person who takes delivery thereof in the form of a beneficial interest in the same Global Note), the transferor of such beneficial interest must deliver to the Registrar (A) (1) a written order from a Participant or an Indirect Participant given to the Depositary in accordance with the Applicable Procedures directing the Depositary to credit or cause to be credited a beneficial interest in another Global Note in an amount equal to the beneficial interest to be transferred or exchanged and (2) instructions given in accordance with the Applicable Procedures containing information regarding the Participant account to be credited with such increase or (B) (1) a written order from a Participant or an Indirect Participant given to the Depositary in accordance with the Applicable Procedures directing the Depositary to cause to be issued a Definitive Note in an amount equal to the beneficial interest to be transferred or exchanged and (2) instructions given by the Depositary to the Registrar containing information regarding the Person in whose name such Definitive Note shall be registered to effect the transfer or exchange referred to in (1) above; provided that (x) no transfer or exchange of a beneficial interest in a Global Note for a Definitive Note shall be effective under clause (B) hereof unless permitted by Applicable Procedures of the Depositary, and (y) beneficial interests in a Global Note may be exchanged for Definitive Notes only upon at least 20 days prior written notice given to the Trustee by or on behalf of

11

the Depositary in accordance with Applicable Procedures. Upon satisfaction of all of the requirements for transfer or exchange of beneficial interests in Global Notes contained in this Indenture, the Trustee shall adjust the principal amount of the relevant Global Note(s) pursuant to Section 2.6(g) hereof.

     (c) Transfer or Exchange of Beneficial Interests for Definitive Notes.

     If any holder of a beneficial interest in a Global Note proposes to exchange such beneficial interest for a Definitive Note or to transfer such beneficial interest to a Person who takes delivery thereof in the form of a Definitive Note, then, upon satisfaction of the conditions set forth in Section 2.6(b)(ii) hereof, the Trustee shall cause the aggregate principal amount of the applicable Global Note to be reduced accordingly pursuant to Section 2.6(g) hereof, and the Company shall execute and the Trustee shall authenticate and make available for delivery to the Person designated in the instructions a Definitive Note in the appropriate principal amount. Any Definitive Note issued in exchange for a beneficial interest pursuant to this Section 2.6(c) shall be registered in such name or names and in such authorized denomination or denominations as the holder of such beneficial interest shall instruct the Registrar through instructions from the Depositary and the Participant or Indirect Participant. The Trustee shall make available for delivery such Definitive Notes to the Persons in whose names such Notes are so registered.

     (d) Transfer and Exchange of Definitive Notes for Beneficial Interests.

     (i) A Holder of a Definitive Note may exchange such Note for a beneficial interest in a Global Note or transfer such Definitive Notes to a Person who takes delivery thereof in the form of a beneficial interest in a Global Note at any time. Upon receipt of a request for such an exchange or transfer, the Trustee shall cancel the applicable Definitive Note and increase or cause to be increased the aggregate principal amount of one of the Global Notes.

     (ii) If any such exchange or transfer from a Definitive Note to a beneficial interest is effected pursuant to subparagraph (i) above at a time when a Global Note has not yet been issued, the Company shall issue and, upon receipt of an Authentication Order in accordance with Section 2.2 hereof, the Trustee shall authenticate one or more Global Notes in an aggregate principal amount equal to the principal amount of beneficial interests transferred pursuant to subparagraph (i) above.

     (e) Transfer of Definitive Notes for Definitive Notes. A Holder of Definitive Notes may transfer such Notes to a Person who takes delivery thereof in the form of a Definitive Note. Upon receipt of a request for such a transfer, the Registrar shall register the Definitive Notes pursuant to the instructions from the Holder thereof. Prior to such registration of transfer, the requesting Holder shall present or surrender to the Registrar the Definitive Notes duly endorsed or accompanied by a written instruction of transfer in

12

form satisfactory to the Registrar duly executed by such Holder or by his attorney, duly authorized in writing.

     (f) Global Note Legend. Each Global Note shall bear a legend in substantially the following form:

“THIS GLOBAL NOTE IS HELD BY THE DEPOSITARY (AS DEFINED IN THE INDENTURE GOVERNING THIS NOTE) OR ITS NOMINEE IN CUSTODY FOR THE BENEFIT OF THE BENEFICIAL OWNERS HEREOF, AND IS NOT TRANSFERABLE TO ANY PERSON UNDER ANY CIRCUMSTANCES EXCEPT THAT (I) THE TRUSTEE MAY MAKE SUCH NOTATIONS HEREON AS MAY BE REQUIRED PURSUANT TO ARTICLE 2 OF THE INDENTURE, (II) THIS GLOBAL NOTE MAY BE EXCHANGED IN WHOLE BUT NOT IN PART PURSUANT TO SECTION 2.6(a) OF THE INDENTURE, (III) THIS GLOBAL NOTE MAY BE DELIVERED TO THE TRUSTEE FOR CANCELLATION PURSUANT TO SECTION 2.11 OF THE INDENTURE AND (IV) THIS GLOBAL NOTE MAY BE TRANSFERRED TO A SUCCESSOR DEPOSITARY WITH THE PRIOR WRITTEN CONSENT OF THE COMPANY.”

“UNLESS THIS NOTE IS PRESENTED BY AN AUTHORIZED REPRESENTATIVE OF THE DEPOSITARY (AS DEFINED IN THE INDENTURE GOVERNING THIS NOTE), TO THE COMPANY OR ITS AGENT FOR REGISTRATION OF TRANSFER, EXCHANGE, OR PAYMENT, AND ANY CERTIFICATE ISSUED IS REGISTERED IN THE NAME OF CEDE & CO. OR IN SUCH OTHER NAME AS IS REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF THE DEPOSITARY (AND ANY PAYMENT IS MADE TO CEDE & CO. OR TO SUCH OTHER ENTITY AS IS REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF THE DEPOSITARY), ANY TRANSFER, PLEDGE, OR OTHER USE HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL INASMUCH AS THE REGISTERED OWNER HEREOF, CEDE & CO., HAS AN INTEREST HEREIN.”

     (g) Cancellation and/or Adjustment of Global Notes. At such time as all beneficial interests in a particular Global Note have been exchanged for Definitive Notes or a particular Global Note has been redeemed, repurchased or canceled in whole and not in part, each such Global Note shall be returned to or retained and canceled by the Trustee in accordance with Section 2.11 hereof. At any time prior to such cancellation, if any beneficial interest in a Global Note is exchanged for or transferred to a Person who will take delivery thereof in the form of a beneficial interest in another Global Note or for Definitive Notes, the principal amount of Notes represented by such Global Note shall be reduced accordingly and an endorsement shall be made on such Global Note, by the Trustee, the Note Custodian or the Depositary at the direction of the Trustee, to reflect

13

such reduction; and if the beneficial interest is being exchanged for or transferred to a Person who will take delivery thereof in the form of a beneficial interest in another Global Note, such other Global Note shall be increased accordingly and an endorsement shall be made on such Global Note, by the Trustee, the Note Custodian or by the Depositary at the direction of the Trustee, to reflect such increase.

     (h) General Provisions Relating to Transfers and Exchanges.

     (i) To permit registrations of transfers and exchanges in accordance with the other provisions of this Indenture, the Company shall execute and the Trustee shall authenticate Global Notes and Definitive Notes upon the Company’s order or at the Registrar’s request.

     (ii) No service charge shall be made to a holder of a beneficial interest in a Global Note or to a Holder of a Definitive Note for any registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any transfer tax or similar governmental charge payable in connection therewith (other than any such transfer taxes or similar governmental charge payable upon exchange or transfer pursuant to Sections 2.10, 3.6 and 9.5 hereof).

     (iii) The Registrar shall not be required to register the transfer or exchange of any Note selected for redemption in whole or in part, except the unredeemed portion of any Note being redeemed in part.

     (iv) All Global Notes and Definitive Notes issued upon any registration of transfer or exchange of Global Notes or Definitive Notes shall be the valid obligations of the Company, evidencing the same debt, and entitled to the same benefits under this Indenture, as the Global Notes or Definitive Notes surrendered upon such registration of transfer or exchange.

     (v) The Company shall not be required (A) to issue, to register the transfer of or to exchange Notes during a period beginning at the opening of business 15 days before the day of mailing of a notice of redemption of Notes for redemption under Section 3.3 hereof and ending at the close of business on the day of such mailing, (B) to register the transfer of or to exchange any Note so selected for redemption in whole or in part, except the unredeemed portion of any Note being redeemed in part or (C) to register the transfer of or to exchange a Note between a record date and the next succeeding Interest Payment Date.

     (vi) Prior to due presentment for the registration of a transfer of any Note, the Trustee, any Agent and the Company may deem and treat the Person in whose name any Note is registered as the absolute owner of such Note for the purpose of receiving payment of principal of and interest on such Notes and for all other purposes, and none of the Trustee, any Agent or the Company shall be affected by notice to the contrary.

     (vii) The Trustee shall authenticate Global Notes and Definitive Notes in accordance with the provisions of Section 2.2 hereof.

14

     (viii) All certifications and certificates required to be submitted to the Registrar pursuant to this Section 2.6 to effect a transfer or exchange may be submitted by facsimile.

     (ix) Each Holder of a Note agrees to indemnify the Company and the Trustee against any liability that may result from the transfer, exchange or assignment of such Holder’s Note in violation of any provision of this Indenture and/or applicable United States federal or state securities law.

     (x) The Trustee shall have no obligation or duty to monitor, determine or inquire as to compliance with any restrictions on transfer imposed under this Indenture or under applicable law with respect to any transfer of any interest in any Note (including any transfers between or among Depositary participants or beneficial owners of interests in any Global Note) other than to require delivery of such certificates and other documentation or evidence as are expressly required by, and to do so if and when expressly required by the terms of, this Indenture, and to examine the same to determine substantial compliance as to form with the express requirements hereof.

SECTION 2.7 REPLACEMENT NOTES

     If any mutilated Note is surrendered to the Trustee or the Company and the Trustee receives evidence to its satisfaction of the destruction, loss or theft of any Note, the Company shall issue and the Trustee, upon the written order of the Company signed by two Officers of the Company, shall authenticate a replacement Note if the Trustee’s requirements are met. An indemnity bond must be supplied by the Holder that is sufficient in the judgment of the Trustee and the Company to protect the Company, the Trustee, any Agent and any authenticating agent from any loss that any of them may suffer if a Note is replaced. The Company may charge for its expenses in replacing a Note.

     Every replacement Note is an additional obligation of the Company and shall be entitled to all of the benefits of this Indenture equally and proportionately with all other Notes duly issued hereunder.

SECTION 2.8 OUTSTANDING NOTES

     The Notes outstanding at any time are all the Notes authenticated by the Trustee except for those canceled by it, those delivered to it for cancellation, those reductions in the interest in a Global Note effected by the Trustee in accordance with the provisions hereof, and those described in this Section as not outstanding. Except as set forth in Section 2.9 hereof, a Note does not cease to be outstanding because the Company or an Affiliate of the Company holds the Note.

     If a Note is replaced pursuant to Section 2.7 hereof, it ceases to be outstanding unless the Trustee receives proof satisfactory to it that the replaced Note is held by a bona fide purchaser.

     If the principal amount of any Note is considered paid under Section 4.1 hereof, it ceases to be outstanding and interest on it ceases to accrue. If the Paying Agent (other than the

15

Company, a Subsidiary or an Affiliate of any thereof) holds, on a redemption date or maturity date, money sufficient to pay Notes payable on that date, then on and after that date such Notes shall be deemed to be no longer outstanding and shall cease to accrue interest.

SECTION 2.9 TREASURY NOTES

     In determining whether the Holders of the required principal amount of Notes have concurred in any direction, waiver or consent, Notes owned by the Company, or by any Person directly or indirectly controlling or controlled by or under direct or indirect common control with the Company, shall be considered as though not outstanding, except that for the purposes of determining whether the Trustee shall be protected in relying on any such direction, waiver or consent, only Notes that a Responsible Officer of the Trustee actually knows are so owned shall be so disregarded.

SECTION 2.10 TEMPORARY NOTES

     Until Definitive Notes are ready for delivery, the Company may prepare and the Trustee shall authenticate temporary Notes upon a written order of the Company signed by two Officers of the Company. Temporary Notes shall be substantially in the form of Definitive Notes but may have variations that the Company considers appropriate for temporary Notes and as shall be reasonably acceptable to the Trustee. Without unreasonable delay, the Company shall prepare and the Trustee shall authenticate Definitive Notes in exchange for temporary Note. Holders of temporary Notes shall be entitled to all of the benefits of this Indenture.

SECTION 2.11 CANCELLATION

     The Company at any time may deliver Notes to the Trustee for cancellation. The Registrar and Paying Agent shall forward to the Trustee any Notes surrendered to them for registration of transfer, exchange or payment. The Trustee and no one else shall cancel all Notes surrendered for registration of transfer, exchange, payment, replacement or cancellation and shall return such canceled Notes to the Company. The Company may not issue new Notes to replace Notes that it has paid or that have been delivered to the Trustee for cancellation.

SECTION 2.12 DEFAULTED INTEREST

     If the Company defaults in a payment of interest on the Notes, it shall pay the defaulted interest in any lawful manner plus, to the extent lawful, interest payable on the defaulted interest, to the Persons who are Holders on a subsequent special record date, in each case at the rate provided in the Notes and in Section 4.1 hereof. The Company shall promptly notify the Trustee in writing of the amount of defaulted interest proposed to be paid on each Note and the date of the proposed payment. The Company shall fix or cause to be fixed each such special record date and payment date, provided that no such special record date shall be less than 10 days prior to the related payment date for such defaulted interest. At least 15 days before the special record date, the Company (or, upon the written request of the Company, the Trustee in the name and at the expense of the Company) shall mail or cause to be mailed to Holders a notice that states the special record date, the related payment date and the amount of such interest to be paid.

16

SECTION 2.13 CUSIP NUMBERS

     The Company in issuing the Notes may use “CUSIP” numbers (if then generally in use), and, if so, the Trustee shall use “CUSIP” numbers in notices of redemption as a convenience to Holders; provided that any such notice may state that no representation is made as to the correctness of such numbers either as printed on the Notes or as contained in any notice of a redemption and that reliance may be placed only on the other identification numbers printed on the Notes, and any such redemption shall not be affected by any defect in or omission of such numbers. The Company will promptly notify the Trustee of any change in the “CUSIP” numbers.

ARTICLE 3
REDEMPTION AND PREPAYMENT

SECTION 3.1 NOTICES TO TRUSTEE

     If the Company elects to redeem Notes pursuant to the optional redemption provisions of Section 3.7 hereof, it shall furnish to the Trustee, at least 45 days (unless a shorter period shall be agreed to by the Trustee in writing) but not more than 75 days before a redemption date (but in any event prior to the notice provided pursuant to Section 3.3 hereof), an Officers’ Certificate setting forth (i) the clause of this Indenture pursuant to which the redemption shall occur, (ii) the redemption date, (iii) the principal amount of Notes to be redeemed and (iv) the redemption price.

SECTION 3.2 SELECTION OF NOTES TO BE REDEEMED

     If less than all of the Notes are to be redeemed or purchased at any time, the Trustee shall select the Notes to be redeemed or purchased among the Holders of the Notes in compliance with the requirements of the principal national securities exchange, if any, on which the Notes are listed or, if the Notes are not so listed, on a pro rata basis, by lot or in accordance with any other method the Trustee considers fair and appropriate; provided, however, that if a partial redemption is made with the proceeds of an Equity Offering, selection of the Notes or portions thereof for redemption shall be made by the Trustee only on a pro rata basis or on as nearly a pro rata basis as is practicable (subject to the procedures of the Depositary), unless such method is prohibited. Any such determination by the Trustee shall be conclusive. In the event of partial redemption by lot, the particular Notes to be redeemed shall be selected, unless otherwise provided herein, not less than 30 nor more than 60 days prior to the redemption date by the Trustee from the outstanding Notes not previously called for redemption.

     The Trustee shall promptly notify the Company in writing of the Notes selected for redemption and, in the case of any Note selected for partial redemption, the principal amount thereof to be redeemed. Notes and portions of Notes selected shall be in amounts of $1,000 or whole multiples of $1,000; except that if all of the Notes of a Holder are to be redeemed, the entire outstanding amount of Notes held by such Holder, even if not a multiple of $1,000, shall be redeemed. Except as provided in the preceding sentence, provisions of this Indenture that apply to Notes called for redemption also apply to portions of Notes called for redemption.

17

SECTION 3.3 NOTICE OF REDEMPTION

     Subject to the provisions of Section 3.7 hereof, at least 30 days but not more than 60 days before an optional redemption date, the Company shall mail or cause to be mailed, by first class mail, a notice of redemption to each Holder whose Notes are to be redeemed at its registered address.

     The notice shall identify the Notes to be redeemed and shall state:

     (a) the redemption date;

     (b) the redemption price;

     (c) if any Note is being redeemed in part, the portion of the principal amount of such Note to be redeemed and that, after the redemption date upon surrender of such Note, a new Note or Notes in principal amount equal to the unredeemed portion shall be issued upon cancellation of the original Note;

     (d) the name and address of the Paying Agent;

     (e) that Notes called for redemption must be surrendered to the Paying Agent to collect the redemption price;

     (f) that, unless the Company defaults in making such redemption payment, interest on Notes called for redemption ceases to accrue on and after the redemption date;

     (g) the paragraph of the Notes or Section of this Indenture pursuant to which the Notes called for redemption are being redeemed; and

     (h) that no representation is made as to the correctness or accuracy of the CUSIP number, if any, listed in such notice or printed on the Notes.

     At the Company’s request, the Trustee shall give the notice of redemption in the Company’s name and at its expense; provided, however, that the Company shall have delivered to the Trustee at least 30 days (unless a shorter period shall be agreed to by the Trustee in writing) but not more than 60 days prior to the redemption date, an Officers’ Certificate requesting that the Trustee give such notice and setting forth the information to be stated in such notice as provided in the preceding paragraph.

SECTION 3.4 EFFECT OF NOTICE OF REDEMPTION

     Once notice of redemption is mailed in accordance with Section 3.3 hereof, Notes called for redemption shall become irrevocably due and payable on the redemption date at the redemption price. A notice of redemption may not be conditional.

     A notice of redemption shall be deemed to be given when mailed, whether or not the Holder receives the notice. In any event, failure to give such notice, or any defect in such notice,

18

shall not affect the validity of the proceedings for the redemption of the Notes held by Holders to whom such notice was properly given.

SECTION 3.5 DEPOSIT OF REDEMPTION PRICE

     On or prior to the redemption date, the Company shall deposit with the Trustee or with the Paying Agent money sufficient to pay the redemption price of and accrued and unpaid interest on all Notes to be redeemed on that date. The Trustee or the Paying Agent shall promptly return to the Company any money deposited with the Trustee or the Paying Agent by the Company in excess of the amounts necessary to pay the redemption price of, and accrued and unpaid interest on, all Notes to be redeemed.

     If the Company complies with the provisions of the preceding paragraph, on and after the redemption date, interest shall cease to accrue on the Notes or the portions of Notes called for redemption. If a Note is redeemed on or after an interest record date but on or prior to the related Interest Payment Date, then any accrued and unpaid interest shall be paid to the Person in whose name such Note was registered at the close of business on such record date. If any Note called for redemption shall not be so paid upon surrender for redemption because of the failure of the Company to comply with the preceding paragraph, interest shall be paid on the unpaid principal from the redemption date until such principal is paid, and to the extent lawful on any interest not paid on such unpaid principal, in each case at the rate provided in the Notes and in Section 4.1 hereof.

SECTION 3.6 NOTES REDEEMED IN PART

     Upon surrender of a Note that is redeemed in part, the Company shall issue and, upon receipt of an Authentication Order in accordance with Section 2.2 with respect to such Notes, the Trustee shall authenticate for the Holder at the expense of the Company a new Note equal in principal amount to the unredeemed portion of the Note surrendered.

SECTION 3.7 OPTIONAL REDEMPTION

     (a) The Company may redeem any or all of the Notes at any time on or after August 15, 2010 at the redemption prices set forth in paragraph 5 of the Note attached hereto.

     (b) From time to time, on or prior to August 15, 2008, the Company may, at its option, use the net cash proceeds of one or more Equity Offerings to redeem up to 35% of the aggregate principal amount of the Notes issued under this Indenture at a redemption price of 106.125% of the principal amount thereof, plus accrued and unpaid interest thereon, if any, to the date of redemption; provided that (i) at least 65% of the original principal amount of the Notes issued under this Indenture shall remain outstanding immediately after each such redemption, and (ii) the Company shall make such redemption not more than 90 days after the consummation of any such Equity Offering.

     (c) Any redemption pursuant to this Section 3.7 shall be made pursuant to the provisions of Sections 3.1 through 3.6 hereof.

     The Company shall pay or cause to be paid the principal of, premium, if any, and interest on, the Notes on the dates and in the manner provided in the Notes and this Indenture. Principal and interest, if any, shall be considered paid on the date due if the Paying Agent, if other than the Company or a Subsidiary thereof, holds as of 10:00 a.m. New York City Time on the due date money deposited by the Company in immediately available funds and designated for and sufficient to pay all principal, premium, if any, and interest then due.

     The Company shall maintain in the Borough of Manhattan, the City of New York, an office or agency (which may be an office of the Trustee or an Affiliate of the Trustee, Registrar or co-registrar) where Notes may be surrendered for registration of transfer or for exchange and where notices and demands to or upon the Company in respect of the Notes and this Indenture may be served. The Company shall give prompt written notice to the Trustee of the location, and any change in the location, of such office or agency. If at any time the Company shall fail to maintain any such required office or agency or shall fail to furnish the Trustee with the address thereof, such presentations, surrenders, notices and demands may be made or served at the Corporate Trust Office of the Trustee.

     The Company may also from time to time designate one or more other offices or agencies where the Notes may be presented or surrendered for any or all such purposes and may from time to time rescind such designations; provided, however, that no such designation or rescission shall in any manner relieve the Company of its obligation to maintain an office or agency in the Borough of Manhattan, the City of New York for such purposes. The Company shall give prompt written notice to the Trustee of any such designation or rescission and of any change in the location of any such other office or agency.

     The Company hereby designates the office of the Trustee’s Affiliate at 101 Barclay Street, Floor 21 West, New York, New York 10286, as one such office or agency of the Company in accordance with Section 2.3 hereof.

SECTION 4.3 STATEMENT BY OFFICERS AS TO DEFAULT

     The Company will deliver to the Trustee, within 120 days after the end of each fiscal year of the Company ending after the date hereof, an Officers’ Certificate, stating whether or not to the knowledge of the signers thereof a Default or Event of Default has occurred during that fiscal year, specifying all such Defaults or Events of Defaults (as applicable) and the nature and status thereof.

20

     The Company shall deliver to the Trustee, as soon as possible and in any event within five days after the Company becomes aware of the occurrence of any Event of Default or Default, an Officers’ Certificate setting forth the details of such Event of Default or Default and the action which the Company proposes to take with respect thereto.

     Subject to Article 5, the Company shall do or cause to be done all things necessary to preserve and keep in full force and effect (i) its corporate existence, and the corporate, partnership or other existence of each of its Restricted Subsidiaries, in accordance with the respective organizational documents (as the same may be amended from time to time) of the Company or any such Restricted Subsidiary and (ii) the rights (charter and statutory), licenses and franchises of the Company and its Restricted Subsidiaries; provided, however, that the Company shall not be required to preserve any such right, license or franchise, or the corporate, partnership or other existence of any of its Restricted Subsidiaries, if the Board of Directors shall determine that the preservation thereof is no longer desirable in the conduct of the business of the Company and its Restricted Subsidiaries, taken as a whole, and that the loss thereof is not adverse in any material respect to the Holders of the Notes.

SECTION 4.5 SEC REPORTS; FINANCIAL STATEMENTS

     (a) The Company shall file with the Trustee, within 15 days after it files the same with the SEC, copies of the annual reports and the information, documents and other reports (or copies of such portions of any of the foregoing) as the SEC may by rules and regulations prescribe that the Company is required to file with the SEC pursuant to Section 13 or 15(d) of the Exchange Act. The Company shall also comply with the provisions of TIA Section 314(a).

     (b) Delivery of such reports, information and documents to the Trustee under this Section 4.5 is for informational purposes only and the Trustee’s receipt of such shall not constitute constructive notice of any information contained therein or determinable from information contained therein, including the Company’s compliance with any of its covenants under this Article IV (as to which the Trustee is entitled to rely exclusively on Officers’ Certificates).

SECTION 4.6 LIMITATION ON LIENS

     So long as any of the Notes are outstanding, the Company shall not at any time create, incur, issue, assume or guarantee, and shall not cause, suffer or permit a Restricted Subsidiary to create, incur, issue, assume or guarantee, any Secured Debt without making effective provision (and the Company covenants that in such case it will make or cause to be made such effective provision) whereby the Notes then outstanding and any other indebtedness of or guaranteed by the Company or any Restricted Subsidiary then entitled thereto, subject to applicable priorities of payment, shall be secured, by a Lien equally and ratably with any and all other obligations and indebtedness thereby secured, so long as such other obligations and indebtedness shall be so secured; provided, that if any such Lien securing such Secured Debt ceases to exist, such equal and ratable security for the benefit of the Holders of Notes shall automatically cease to exist

21

without any further action; provided, further, that if such Secured Debt is expressly subordinated to the Notes, the Lien securing such subordinated Secured Debt shall be subordinate and junior to the Lien securing the Notes with the same relative priority as such Secured Debt shall have with respect to the Notes; and provided further, that the foregoing covenants shall not be applicable to the Secured Debt that is secured by Permitted Liens.

     Notwithstanding the foregoing provisions of this Section 4.6, the Company and its Restricted Subsidiaries may, without equally and ratably securing the Notes, create, incur, issue, assume or guarantee Secured Debt not otherwise permitted or excepted if the sum of (a) the amount of such Secured Debt plus (b) the aggregate value of Sale and Leaseback Transactions (excluding Sale and Leaseback Transactions identified in (a) through (d) of Section 4.7), does not exceed 10% of Consolidated Net Tangible Assets (as shown in the quarterly consolidated balance sheet of the Company most recently published prior to the date of creation, incurrence, issuance, assumption or guarantee).

SECTION 4.7 LIMITATION ON SALE AND LEASEBACK TRANSACTIONS

     The Company will not, nor will it permit any of its Restricted Subsidiaries to, engage in a Sale and Leaseback Transaction, unless: (a) such Sale and Leaseback Transaction occurs within one year from the date of completion of the acquisition of the Principal Property subject thereto or the date of the completion of construction, development or substantial repair or improvements, or commencement of full operations, on such Principal Property, whichever is later, (b) the Sale and Leaseback Transaction involves a lease for a period, including renewals, of not more than three years, (c) the Company or such Restricted Subsidiary would be entitled to incur Secured Debt secured by a Lien on the Principal Property subject thereto in a principal amount equal to or exceeding the net sale proceeds from such Sale and Leaseback Transaction without equally and ratably securing the Notes pursuant to Section 4.6, or (d) the Company or such Restricted Subsidiary, within a one-year period after the Sale and Leaseback Transaction, applies or causes to be applied an amount not less than the net sale proceeds from such Sale and Leaseback Transaction to (i) the redemption of the Notes or the prepayment, repayment, reduction or retirement of any indebtedness of the Company that ranks pari passu with the Notes or (ii) the expenditure or expenditures for Principal Property used or to be used in the ordinary course of business of the Company or any of its Restricted Subsidiaries.

     Notwithstanding the foregoing, the Company may, and may permit each of its Restricted Subsidiaries, to, effect any Sale and Leaseback Transaction that is not excepted by clauses (a) through (d) (inclusive) of the above paragraph, provided that, after giving effect thereto and the application of proceeds, if any, received by the Company or any its Restricted Subsidiaries as a result thereof, the net sale proceeds from such Sale and Leaseback Transaction, together with the aggregate principal amount of all Secured Debt then outstanding (other than the Notes) secured by Liens upon Principal Property (which are not Permitted Liens) would not exceed 10% of the Consolidated Net Tangible Assets (as shown in the quarterly consolidated balance sheet of the Company most recently published prior to the date the Sale and Leaseback Transaction is effected).

     The Company may (a) consolidate with or merge into, or (b) sell, convey, transfer, lease or otherwise dispose of its properties and assets substantially as an entirety to, any Person, provided that (i) in the case of any such consolidation or merger, the Company is the continuing entity or, if the Company is not the continuing entity, the continuing entity is a Person organized and validly existing under the laws of the United States, any political subdivision thereof or any State thereof and assumes by supplemental indenture all of the Company’s obligations on the Notes and under the Indenture, and (ii) after giving effect to the transaction no Event of Default, and no event which, after notice or lapse of time or both, would become an Event of Default, shall exist. Upon a disposition of assets described in clause (b) of the preceding sentence, the Company will be released from any further liability under the Notes and the Indenture.

SECTION 5.2 SUCCESSOR ENTITY SUBSTITUTED

     Upon any consolidation or merger, transfer or lease of its properties and assets substantially as an entirety in accordance with Section 5.1 hereof, the successor entity formed by such consolidation with, or into which the Company is merged or to which such conveyance, transfer or lease of its properties and assets is made shall succeed to, and be substituted for (so that from and after the date of such consolidation or merger, or conveyance transfer or lease of its property and assets substantially as an entirety, the provisions of this Indenture referring to the “Company” shall refer instead to the successor entity and not to the Company), and may exercise every right and power of the Company under this Indenture with the same effect as if such successor Person had been named as the Company herein.

ARTICLE 6
DEFAULTS AND REMEDIES

SECTION 6.1 EVENTS OF DEFAULT

     An “Event of Default” occurs hereunder with respect to the Notes if:

     (a) the Company defaults in the payment when due of principal of the Notes;

     (b) the Company defaults in payment when due of interest on the Notes and such default continues for a period of 30 days;

     (c) the Company or any of its Restricted Subsidiaries fails to observe or perform any covenant of the Company (other than the covenants described in clauses (a) or (b) above) in the Notes or this Indenture for 60 days after notice to the Company by the Trustee or the Holders of at least 25% in aggregate principal amount of the Notes then outstanding;

     (d) indebtedness of the Company or any Subsidiary is not paid when due within the applicable grace period, if any, or is accelerated by the holders thereof and, in

23

either case, the principal amount of such unpaid or accelerated indebtedness exceeds $20 million;

     (e) the Company or any of its Significant Subsidiaries or any group of Subsidiaries that, when taken together, would constitute a Significant Subsidiary:

     (i) commences a voluntary case;

     (ii) consents to the entry of an order for relief against it in an involuntary case;

     (iii) consents to the appointment of a custodian of it or for all or substantially all of its property; or

     (iv) makes a general assignment for the benefit of its creditors.

     (f) a court of competent jurisdiction enters an order or decree under the Bankruptcy Code that:

     (i) is for relief against the Company or any of its Significant Subsidiaries or any group of Subsidiaries that, when taken together, would constitute a Significant Subsidiary, in an involuntary case;

     (ii) appoints a Custodian of the Company or any of its Significant Subsidiaries or any group of Subsidiaries that, when taken together, would constitute a Significant Subsidiary, or for all or substantially all of the property of the Company or any group of Subsidiaries that, when taken together, would constitute a Significant Subsidiary; or

     (iii) orders the liquidation of the Company or any of its Significant Subsidiaries or any group of Subsidiaries that, when taken together, would constitute a Significant Subsidiary.

and the order or decree remains unstayed and in effect for 60 consecutive days.

SECTION 6.2 ACCELERATION

     If any Event of Default (other than an Event of Default specified in clauses (e) or (f) of Section 6.1) shall occur and be continuing, either the Trustee or the Holders of at least 25% of the then outstanding Notes by notice to the Company may declare the principal amount of the Notes to be due and payable immediately. If an Event of Default specified in clauses (e) or (f) of Section 6.1 shall occur, the principal amount of all the then outstanding Notes will automatically, and without any action by the Trustee or any Holder, become immediately due and payable. After any acceleration, but before a judgment or decree for the payment of the money due has been obtained by the Trustee, the Holders of a majority in aggregate principal amount of the then outstanding Notes, by written notice to the Trustee, may rescind and annul such acceleration and its consequences if all Events of Default, other than the non-payment of accelerated principal, have been cured or waived pursuant to the terms of this Indenture.

24

SECTION 6.3 OTHER REMEDIES

     If an Event of Default occurs and is continuing, the Trustee may pursue any available remedy to collect the payment of principal, premium, if any, and accrued and unpaid interest, if any, on the Notes or to enforce the performance of any provision of the Notes or this Indenture.

     The Trustee may maintain a proceeding even if it does not possess any of the Notes or does not produce any of them in the proceeding. A delay or omission by the Trustee or any Holder of a Note in exercising any right or remedy accruing upon an Event of Default shall not impair the right or remedy or constitute a waiver of or acquiescence in the Event of Default. All remedies are cumulative to the extent permitted by law.

SECTION 6.4 WAIVER OF PAST DEFAULTS

     The Holders of a majority in aggregate principal amount of the outstanding Notes may on behalf of the Holders of all of the Notes waive any past Default or Event of Default hereunder and its consequences, except a Default:

     (a) in the payment of the principal of or any premium or interest on any Note, or

     (b) in respect of any other covenant or provision hereof which, under Section 9.2 hereof, cannot be modified or amended without the consent of the Holder of each outstanding Note.

     Upon any such waiver, such Default or Event of Default shall cease to exist and shall be deemed to have been cured, for every purpose of this Indenture; but no such waiver shall extend to any subsequent or other Default or Event of Default or impair any right consequent thereon.

SECTION 6.5 CONTROL BY MAJORITY

     Subject to Section 7.2(f) hereof, Holders of a majority in principal amount of the then outstanding Notes (together as a single class) may direct the time, method and place of conducting any proceeding for exercising any remedy available to the Trustee or exercising any trust or power conferred on the Trustee.

SECTION 6.6 LIMITATION ON SUITS

     A Holder of a Note may institute any proceeding with respect to this Indenture, or for the appointment of a receiver or a trustee, or for any other remedy thereunder with respect to this Indenture or the Note only if:

     (a) the Holder of a Note has previously given to the Trustee written notice of a continuing Event of Default;

     (b) the Holders of at least 25% in aggregate principal amount of the Notes make a written request to the Trustee to institute a proceeding or pursue a remedy as Trustee;

25

     (c) such Holder of a Note or Holders of Notes offer and, if requested, provide to the Trustee indemnity satisfactory to the Trustee against any loss, liability or expense to be incurred in compliance with such request;

     (d) the Trustee does not comply with the request within 60 days after receipt of the request and the offer and, if requested, the provision of indemnity; and

     (e) during such 60-day period the Holders of a majority in principal amount of the Notes do not give the Trustee a direction inconsistent with the request.

     A Holder of a Note may not use this Indenture to prejudice the rights of another Holder of a Note or to obtain a preference or priority over another Holder of a Note or to enforce any right under this Indenture, except in the manner herein provided and for the equal and ratable benefit of all of such Holders.

SECTION 6.7 RIGHTS OF HOLDERS OF NOTES TO RECEIVE PAYMENT AND INSTITUTE PROCEEDINGS

     Notwithstanding any other provision of this Indenture, the right of any Holder of a Note to receive payment of principal of, and premium, if any, and interest on, the Note on or after the respective due dates expressed in the Note, or to bring suit for the enforcement of any such payment on or after such respective dates, shall not be impaired, affected or limited in any way (including by any limitation set forth in Section 6.6 hereof) without the consent of the Holder of each Note affected thereby.

SECTION 6.8 COLLECTION SUIT BY TRUSTEE

     If an Event of Default specified in Section 6.1(a) or (b) hereof occurs and is continuing, the Trustee is authorized to recover judgment in its own name and as trustee of an express trust against the Company for the whole amount of principal of, and premium, if any, and interest remaining unpaid on, the Notes and interest on overdue principal and, to the extent lawful, interest and such further amount as shall be sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel.

SECTION 6.9 TRUSTEE MAY FILE PROOFS OF CLAIM

     The Trustee is authorized to file such proofs of claim and other papers or documents as may be necessary or advisable in order to have the claims of the Trustee (including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel) and the Holders of the Notes allowed in any judicial proceedings relative to the Company (or any other obligor upon the Notes), its creditors or its property and shall be entitled and empowered to collect, receive and distribute any money or other property payable or deliverable on any such claims and any custodian in any such judicial proceeding is hereby authorized by each Holder to make such payments to the Trustee, and in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee any amount due to it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under

26

Section 7.7 hereof. To the extent that the payment of any such compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 7.7 hereof out of the estate in any such proceeding, shall be denied for any reason, payment of the same shall be secured by a Lien on, and shall be paid out of, any and all distributions, dividends, money, securities and other properties that the Holders may be entitled to receive in such proceeding whether in liquidation or under any plan of reorganization or arrangement or otherwise. Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting any Notes or the rights of any Holder, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding.

SECTION 6.10 PRIORITIES

     If the Trustee collects any money pursuant to this Article, it shall pay out the money in the following order:

     First: to the Trustee, its agents and attorneys for amounts due under Section 7.7 hereof, including payment of all compensation, expense, and liabilities incurred, and all advances made, by the Trustee and the costs and expenses of collection;

     Second: to Holders of the Notes for amounts due and unpaid on the Notes for principal, premium, if any, and interest, ratably, without preference or priority of any kind, according to the amounts due and payable on the Notes for principal, premium, if any and interest, respectively; and

     Third: to the Company or to such party as a court of competent jurisdiction shall direct.

     The Trustee may fix a record date and payment date for any payment to Holders of Notes pursuant to this Section 6.10.

SECTION 6.11 UNDERTAKING FOR COSTS

     In any suit for the enforcement of any right or remedy under this Indenture or in any suit against the Trustee for any action taken or omitted by it as a Trustee, a court in its discretion may require the filing by any party litigant in the suit of an undertaking to pay the cost of the suit, and the court in its discretion may assess reasonable costs, including reasonable attorneys’ fees and expenses, against any party litigant in the suit, having due regard to the merits and good faith of the claims or defenses made by the party litigant. This Section does not apply to a suit by the Trustee, a suit by a Holder of a Note pursuant to Section 6.7 hereof, or a suit by Holders of more than 10% in principal amount of the then outstanding Notes.

TRUSTEE

SECTION 7.1 DUTIES OF TRUSTEE

     (a) If an Event of Default has occurred and is continuing, the Trustee shall exercise such of the rights and powers vested in it by this Indenture, and use the same degree of care and skill in its exercise, as a prudent man would exercise or use under the circumstances in the conduct of his own affairs.

     (b) Except during the continuance of an Event of Default:

     (i) The Trustee need perform only those duties that are specifically set forth in this Indenture and the TIA and no others, and no implied covenants or obligations shall be read into this Indenture against the Trustee.

     (i) this paragraph does not limit the effect of paragraph (b) of this Section;

     (ii) the Trustee shall not be liable for any error of judgment made in good faith by a Responsible Officer, unless it is proved that the Trustee was negligent in ascertaining the pertinent facts; and

     (iii) the Trustee shall not be liable with respect to any action it takes or omits to take in good faith in accordance with a direction received by it pursuant to Section 6.5 hereof.

     (d) Whether or not therein expressly so provided, every provision of this Indenture that in any way relates to the Trustee is subject to paragraphs (a), (b), and (c) of this Section.

     (e) No provision of this Indenture shall require the Trustee to expend or risk its own funds or incur any liability. The Trustee shall be under no obligation to exercise

28

any of its rights and powers under this Indenture at the request of any Holders, unless such Holder shall have offered and, if requested, provided to the Trustee security and indemnity satisfactory to it against any loss, liability or expense.

The Trustee shall not be liable for any action it takes or omits to take in good faith in reliance on such Officers’ Certificate or Opinion of Counsel. The Trustee may consult with counsel of its selection and the advice of such counsel or any Opinion of Counsel shall be full and complete authorization and protection from liability in respect of any action taken, suffered or omitted by it hereunder in good faith and in reliance thereon.

     (c) The Trustee may act through its attorneys and agents and shall not be responsible for the misconduct or negligence of any agent appointed with due care.

     (f) Subject to Section 7.1(b) hereof, the Trustee shall be under no obligation to exercise any of the rights or powers vested in it by this Indenture at the request or direction of any of the Holders unless such Holders shall have offered and, if requested, provided to the Trustee security or indemnity satisfactory to the Trustee against the costs, expenses and liabilities (including fees and expenses of its agents and counsel) that might be incurred by it in compliance with such request or direction.

     (g) The Trustee, in its individual or other capacity, may make loans to, accept deposits from, and perform services for, the Company or its Affiliates, and may otherwise deal with the Company or its Affiliates, as if it were not the Trustee, including, without limitation, as a lender under any of the Company’s credit facilities.

     (h) The Trustee shall not be deemed to have notice of any Default or Event of Default unless a Responsible Officer of the Trustee has actual knowledge thereof or

29

unless written notice of any event which is in fact such a default is received by the Trustee at the Corporate Trust Office of the Trustee, and such notice references the Notes and this Indenture.

     (i) The rights, privileges, protections, immunities and benefits given to the Trustee, including, without limitation, its right to be indemnified, are extended to, and shall be enforceable by, the Trustee in each of its capacities hereunder.

SECTION 7.3 INDIVIDUAL RIGHTS OF TRUSTEE

     The Trustee, any Paying Agent, any authenticating agent or registrar in its individual or any other capacity may become the owner or pledgee of Notes and may otherwise deal with the Company or any Affiliate of the Company with the same rights it would have if it were not Trustee. However, in the event that the Trustee acquires any conflicting interest it must eliminate such conflict within 90 days, apply to the SEC for permission to continue as trustee or resign. Any Agent may do the same with like rights and duties. The Trustee is also subject to Sections 7.10 and 7.11 hereof.

     The Trustee shall not be responsible for and makes no representation as to the validity or adequacy of this Indenture or the Notes, it shall not be accountable for the Company’s use of the proceeds from the Notes or any money paid to the Company or upon the Company’s direction under any provision of this Indenture, it shall not be responsible for the use or application of any money received by any Paying Agent other than the Trustee, and it shall not be responsible for any statement or recital herein or any statement in the Notes or any other document in connection with the sale of the Notes or pursuant to this Indenture other than its certificate of authentication.

SECTION 7.5 NOTICE OF DEFAULTS

     If a Default or Event of Default occurs and is continuing and if it is actually known to a Responsible Officer of the Trustee, the Trustee shall mail to Holders of Notes a notice of the Default or Event of Default within 90 days after it occurs. Except in the case of a Default or Event of Default in payment of principal of, or interest or premium, if any, on any Note, the Trustee may withhold the notice if and so long as a committee of its Responsible Officers in good faith determines that withholding the notice is in the interests of the Holders of the Notes.

SECTION 7.6 REPORTS BY TRUSTEE TO HOLDERS OF THE NOTES

     Within 60 days after each March 15 beginning with the March 15 next following the date of this Indenture, and for so long as the Notes remain outstanding, the Trustee shall mail to the Holders of the Notes a brief report dated as of such reporting date that complies with TIA Section 313(a) (but if no event described in TIA Section 313(a) has occurred within the twelve months preceding the reporting date, no report need be transmitted). The Trustee also shall comply with TIA Section 313(b)(2). The Trustee shall also transmit by mail all reports as required by TIA Section 313(c). A copy of each report at the time of its mailing to the Holders of Notes shall be mailed to the Company and filed with the SEC and each stock exchange on which

30

Notes are listed in accordance with TIA Section 313(d). The Company shall promptly notify the Trustee when the Notes are listed on any stock exchange or delisted therefrom.

SECTION 7.7 COMPENSATION AND INDEMNITY

     The Company shall pay to the Trustee from time to time such compensation for its acceptance of this Indenture and services hereunder as the parties shall agree from time to time. The Trustee’s compensation shall not be limited by any law on compensation of a trustee of an express trust. The Company shall reimburse the Trustee promptly upon request for all reasonable disbursements, advances and expenses incurred or made by it in addition to the compensation for its services. Such expenses shall include the reasonable compensation, disbursements and expenses of the Trustee’s agents and counsel.

     The Company shall indemnify the Trustee against any and all losses, liabilities, claims, damages or expenses incurred by it arising out of or in connection with the acceptance or administration of its duties under this Indenture, including the costs and expenses of enforcing this Indenture against the Company (including this Section 7.7) and defending itself against any claim (whether asserted by the Company or any Holder or any other Person) or liability in connection with the exercise or performance of any of its powers or duties hereunder, except to the extent any such loss, liability, claim, damage or expense may be attributable to its negligence or bad faith. The Trustee shall notify the Company promptly of any claim for which it may seek indemnity. Failure by the Trustee to so notify the Company shall not relieve the Company of its obligations hereunder. The Company shall defend the claim and the Trustee shall cooperate in the defense. The Trustee may have separate counsel and the Company shall pay the reasonable fees and expenses of such counsel. The Company need not pay for any settlement made without its consent, which consent shall not be unreasonably withheld.

     The obligations of the Company under this Section 7.7 shall survive the satisfaction and discharge of this Indenture. To secure the Company’s payment obligations in this Section, the Trustee shall have a Lien prior to any of the Notes on all money or property held or collected by the Trustee, except that held in trust to pay principal and interest on particular Notes. Such Lien shall survive the satisfaction and discharge of this Indenture.

     When the Trustee incurs expenses or renders services after an Event of Default specified in Section 6.1(e) or (f) hereof occurs, the expenses and the compensation for the services (including the fees and expenses of its agents and counsel) are intended to constitute expenses of administration under the Bankruptcy Code.

     The Trustee shall comply with the provisions of TIA Section 313(b)(2) to the extent applicable.

SECTION 7.8 REPLACEMENT OF TRUSTEE

     A resignation or removal of the Trustee and appointment of a successor Trustee shall become effective only upon the successor Trustee’s acceptance of appointment as provided in this Section.

31

     The Trustee may resign in writing at any time and be discharged from the trust hereby created by so notifying the Company. The Holders of a majority in principal amount of the then outstanding Notes may remove the Trustee by so notifying the Trustee and the Company in writing.

     The Company may remove the Trustee if:

     (a) the Trustee fails to comply with Section 7.10 hereof;

     (b) the Trustee is adjudged a bankrupt or an insolvent or an order for relief is entered with respect to the Trustee under the Bankruptcy Code;

     (c) a custodian or public officer takes charge of the Trustee or its property; or

     (d) the Trustee becomes incapable of acting.

     If the Trustee resigns or is removed or if a vacancy exists in the office of Trustee for any reason, the Company shall promptly appoint a successor Trustee. Within one year after the successor Trustee takes office, the Holders of a majority in principal amount of the then outstanding Notes may appoint a successor Trustee to replace the successor Trustee appointed by the Company.

     If a successor Trustee does not take office within 60 days after the retiring Trustee resigns or is removed, the retiring Trustee, the Company, or the Holders of at least 10% in principal amount of the then outstanding Notes may, at the expense of the Company, petition any court of competent jurisdiction for the appointment of a successor Trustee.

     If the Trustee, after written request by any Holder of a Note who has been a Holder of a Note for at least six months, fails to comply with Section 7.10 hereof, such Holder of a Note may, at the expense of the Company, petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee.

     A successor Trustee shall deliver a written acceptance of its appointment to the retiring Trustee and to the Company. Thereupon, the resignation or removal of the retiring Trustee shall become effective, and the successor Trustee shall have all the rights, powers and duties of the Trustee under this Indenture. The successor Trustee shall mail a notice of its succession to Holders of the Notes. The retiring Trustee shall promptly transfer all property held by it as Trustee to the successor Trustee, provided all sums owing to the Trustee hereunder have been paid and subject to the Lien provided for in Section 7.7 hereof. Notwithstanding replacement of the Trustee pursuant to this Section 7.8, the Company’s obligations under Section 7.7 hereof shall continue for the benefit of the retiring Trustee.

SECTION 7.9 SUCCESSOR TRUSTEE BY MERGER, ETC.

     If the Trustee consolidates, merges or converts into, or transfers all or substantially all of its corporate trust business to, another corporation, the successor corporation without any further act shall be the successor Trustee.

32

SECTION 7.10 ELIGIBILITY; DISQUALIFICATION

     There shall at all times be a Trustee hereunder that is a corporation organized and doing business under the laws of the United States of America or of any state thereof that is authorized under such laws to exercise corporate trustee power, that is subject to supervision or examination by federal or state authorities and that has, or is the subsidiary of a bank holding company that has, a combined capital and surplus of at least $50,000,000 as set forth in its most recent published annual report of condition. This Indenture shall always have a Trustee who satisfies the requirements of TIA Section 310(a)(1), (2) and (5). The Trustee is subject to TIA Section 310(b).

SECTION 7.11 PREFERENTIAL COLLECTION OF CLAIMS AGAINST COMPANY

     (a) either

     (i) all such Notes theretofore authenticated and delivered (other than (1) such Notes which have been destroyed, lost or stolen and which have been replaced or paid as provided in Section 2.7 and (2) such Notes for whose payment money or Government Securities have theretofore been deposited in trust or segregated and held in trust by the Company and thereafter repaid to the Company or discharged from such trust, as provided in Section 8.8) have been delivered to the Trustee for cancellation; or

     (ii) all such Securities not theretofore delivered to the Trustee for cancellation

     (A) have become due and payable, or

     (B) will become due and payable at their final Stated Maturity within one year,

and the Company, in the case of (A) or (B) above, has deposited or caused to be deposited with the Trustee as trust funds in trust for the purpose an amount of

33

money or Government Securities sufficient to pay and discharge the entire indebtedness on such Notes not theretofore delivered to the Trustee for cancellation, for principal and any premium and interest to the date of such deposit (in the case of such Notes which have become due and payable) or to the Stated Maturity of the principal of the Notes;

     (b) the Company has paid or caused to be paid all other sums payable hereunder by the Company with respect to such Notes; and

     (c) the Company has delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that all conditions precedent herein provided for relating to the satisfaction and discharge of this Indenture with respect to such Notes have been complied with.

     Notwithstanding the satisfaction and discharge of this Indenture with respect to the Notes, the obligations of the Company to the Trustee under Section 7.7 hereof, and, if money or Government Securities shall have been deposited with the Trustee pursuant to subclause (ii) of clause (a) of this Section, the obligations of the Company or Trustee under Section 8.2 hereof and Section 8.9 shall survive.

SECTION 8.2 APPLICATION OF TRUST MONEY

     Subject to the provisions of Section 8.9, all money and Government Securities deposited with the Trustee pursuant to Section 8.1 hereof shall be held in trust and applied by it, in accordance with the provisions of the Notes and this Indenture, to the payment, either directly or through any Paying Agent (including the Company acting as its own Paying Agent) as the Trustee may determine, to the Persons entitled thereto, of the principal and any premium and interest for whose payment such money or Government Securities has been deposited with the Trustee.

SECTION 8.3 OPTION TO EFFECT LEGAL DEFEASANCE OR COVENANT DEFEASANCE

     The Company may, at the option of its Board of Directors evidenced by a resolution set forth in an Officers’ Certificate, at any time, elect to have either Section 8.4 or 8.5 hereof be applied to all outstanding Notes, upon compliance with the conditions set forth in this Article VIII.

SECTION 8.4 DEFEASANCE AND DISCHARGE

     In addition to discharge of the Indenture pursuant to Section 8.1 hereof, the Company shall be deemed to have paid and discharged the entire indebtedness on all the Notes on the date of the deposit referred to in clause (a) of Section 8.6 hereof, and the provisions of this Indenture with respect to the Notes shall no longer be in effect (except as to (1) the rights of Holders of such Notes to receive, solely from the trust fund described in Section 8.6 hereof and as more fully set forth in such Section, payments in respect of the principal of and any premium and interest on such Notes when payments are due (other than by acceleration), (2) the Company’s obligations with respect to such Notes under Sections 2.4, 2.6, 2.7, 2.10, 4.2 and 8.9 hereof, and

34

(3) the rights, powers, trusts, obligations, duties and immunities of the Trustee hereunder), and the Trustee, at the expense of the Company, upon written request of an Officer of the Company, shall execute proper instruments acknowledging the same, if the applicable conditions set forth in Section 8.6 hereof are satisfied (“Defeasance”). For this purpose, such Defeasance means that the Company (and any other obligor of the Notes) shall be deemed to have paid and discharged the entire indebtedness represented by the Notes, which shall thereafter be deemed to be “Outstanding” only for the purposes of Section 8.7 hereof and the rights and obligations referred to in clauses (1) through (3) (inclusive) of this Section 8.4, and to have satisfied all its other obligations under such Notes and this Indenture insofar as such Notes are concerned.

For this purpose, such Covenant Defeasance means that, with respect to the Notes (i) the Company may omit to comply with and shall have no liability in respect of any term, condition or limitation set forth in any such specified Section, whether directly or indirectly by reason of any reference elsewhere herein to any such Section or by reason of any reference in any Section to any other provision herein or in any other document and such omission to comply shall not constitute a Default or Event of Default under Section 6.1 hereof, but, except as specified above, the remainder of this Indenture and such Notes shall be unaffected thereby, and (ii) such Notes shall thereafter be deemed to be not “Outstanding” for the purposes of any request, demand, authorization, direction, notice, waiver, consent or declaration or other action of Holders (and the consequences of any therefor) in connection with such specified covenants, but shall continue to be deemed Outstanding for all other purposes hereunder.

SECTION 8.6 CONDITIONS TO DEFEASANCE OR COVENANT DEFEASANCE

     (c) In order to have Section 8.5 hereof apply to any Notes, as the case may be, the Company shall have delivered to the Trustee an Opinion of Counsel to the effect that the Holders of such Notes will not recognize gain or loss for federal income tax purposes as a result of such deposit and Covenant Defeasance and will be subject to federal income tax on the same amount, in the same manner and at the same times as would have been the case if such deposit and Covenant Defeasance had not occurred.

     (e) Such Defeasance or Covenant Defeasance will not result in a breach or violation of, or constitute a default under, any material agreement or instrument (other than this Indenture) to which the Company or any of its Restricted Subsidiaries is a party or by which the Company or any of its Restricted Subsidiaries is bound.

     (f) The Company shall have delivered to the Trustee an Opinion of Counsel to the effect that on the 91st day following the deposit, the trust funds will not be subject to avoidance under Section 547 of the Bankruptcy Code or any successor provision thereof.

     (h) The Company shall have delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that all conditions precedent provided for or relating to Defeasance or the Covenant Defeasance have been complied with.

The provisions of Section 8.8 hereof shall apply to any money held by the Trustee or any Paying Agent under this Article that remains unclaimed for two years after the Stated Maturity of the Notes for which money or Government Securities have been deposited pursuant to Section 8.6 hereof.

     The Company shall pay and indemnify the Trustee against any tax, fee or other charge imposed on or assessed against the Government Securities deposited pursuant to this Article or the principal and interest received in respect thereof other than any such tax, fee or other charge which by law is for the account of the Holders of outstanding Notes.

SECTION 8.8 REPAYMENT TO COMPANY

37

SECTION 8.9 REINSTATEMENT

     (c) to provide for the assumption of the Company’s obligations to the Holders of any of the Notes in the case of a merger, consolidation or sale of assets of the Company pursuant to Article 5 hereof;

     (d) to make any change that would provide any additional rights or benefits to the Holders of the Notes or that does not adversely affect the legal rights hereunder of any such Holder in any material respect;

     (e) to conform the text of this Indenture or the Notes to any provision of the “Description of the National Oilwell Varco Notes” section of the Company’s Prospectus dated March 20, 2008, relating to the initial offering of the Notes, to the extent that such provision in that “Description of the National Oilwell Varco Notes” was intended to be a verbatim recitation of a provision of this Indenture or the Notes;

SECTION 9.2 WITH CONSENT OF HOLDERS OF NOTES

     Except as provided below in this Section 9.2, the Company and the Trustee may amend or supplement this Indenture and the Notes may be amended or supplemented with the consent of the Holders of a majority in principal amount of the Notes then outstanding (including, without limitation, consents obtained in connection with a tender offer or exchange offer for the Notes), and, subject to Sections 6.4 and 6.7 hereof, any existing Default or Event of Default (other than a Default or Event of Default in the payment of the principal of, or premium, if any, or interest on, the Notes, except a payment default resulting from an acceleration that has been rescinded) or compliance with any provision of this Indenture or the Notes may be waived with the consent of the Holders of a majority in principal amount of the then outstanding Notes (including consents obtained in connection with a tender offer or exchange offer for the Notes).

     Upon the request of the Company accompanied by a resolution of its Board of Directors authorizing the execution of any such amended or supplemental Indenture, and upon the filing with the Trustee of evidence satisfactory to the Trustee of the consent of the Holders of Notes as aforesaid, and upon receipt by a Responsible Officer of the Trustee of the documents described in Section 9.6 hereof, the Trustee shall join with the Company in the execution of such amended or supplemental Indenture. It shall not be necessary for the consent of the Holders of Notes under this Section 9.2 to approve the particular form of any proposed amendment or waiver, but it shall be sufficient if such consent approves the substance thereof.

     After an amendment, supplement or waiver under this Section becomes effective, the Company shall mail to the Holders of Notes affected thereby a notice briefly describing the amendment, supplement or waiver. Any failure of the Company to mail such notice, or any defect therein, shall not, however, in any way impair or affect the validity of any such amended or supplemental Indenture or waiver. Subject to Sections 6.4 and 6.7 hereof, the Holders of a majority in aggregate principal amount of the Notes then outstanding may waive compliance in a particular instance by the Company with any provision of this Indenture or the Notes. However, without the consent of each Holder affected, an amendment or waiver may not (with respect to any Notes held by a nonconsenting Holder):

     (g) reduce the percentage in principal amount of such Note necessary for waiver of compliance with certain provisions of the Indenture or for waiver of certain defaults;

     (h) modify such provisions with respect to modification and waiver; or

SECTION 9.3 COMPLIANCE WITH TRUST INDENTURE ACT

     Every amendment or supplement to this Indenture or the Notes shall be set forth in an amended or supplemental Indenture that complies with the TIA as then in effect.

SECTION 9.4 REVOCATION AND EFFECT OF CONSENTS

     Until an amendment, supplement or waiver becomes effective, a consent to it by a Holder of a Note is a continuing consent by the Holder of a Note and every subsequent Holder of a Note or portion of a Note that evidences the same debt as the consenting Holder’s Note, even if notation of the consent is not made on any Note. However, any such Holder of a Note or subsequent Holder of a Note may revoke the consent as to its Note if the Trustee receives written notice of revocation before the date the waiver, supplement or amendment becomes effective. An amendment, supplement or waiver becomes effective in accordance with its terms and thereafter binds every Holder.

SECTION 9.5 NOTATION ON OR EXCHANGE OF NOTES

     The Trustee may place an appropriate notation about an amendment, supplement or waiver on any Note thereafter authenticated. The Company, in exchange for all Notes, may issue and the Trustee shall authenticate new Notes that reflect the amendment, supplement or waiver.

SECTION 9.6 TRUSTEE TO SIGN AMENDMENTS, ETC.

     The Trustee shall sign any amended or supplemental Indenture authorized pursuant to this Article 9 if the amendment or supplement does not adversely affect the rights, duties, liabilities or immunities of the Trustee. The Trustee may, but shall not be obligated to, enter into any such supplemental Indenture which affects the Trustee’s own rights, duties, liabilities or immunities under this Indenture or otherwise. The Company may not sign an amended or supplemental Indenture until the Board of Directors approves it. In executing any amended or supplemental indenture, the Trustee shall be entitled to receive and (subject to Section 7.1 hereof) shall be fully protected in relying upon, an Officers’ Certificate and an Opinion of Counsel stating that the execution of such amended or supplemental Indenture is authorized or permitted by this Indenture.

SECTION 9.7 RECORD DATES

     Except as otherwise provided in this Indenture or the Notes, the Company will be entitled to set any day as a record date for the purpose of determining the Holders of Notes entitled to give or take any direction, notice, consent, waiver or other action under the Indenture. Pursuant to Section 6.10, the Trustee also will be entitled to set a record date for certain payments to Holders of Notes. If a record date is set for any action to be taken by Holders of the Notes, such action may be taken only by Persons who are Holders of the Notes on the record date. To be effective, such action must be taken by Holders of the requisite principal amount of the Notes within a specified period following the record date. For any particular record date, this period will be 180 days or such shorter period as may be specified by the Company (or the Trustee, if it sets the record date), and may be shortened or lengthened (but not beyond 180 days) from time to time.

1. INTEREST. National Oilwell Varco, Inc., a Delaware corporation (the “Company”), promises to pay interest on the principal amount of this Note at 6¹/₈% per annum, from February 15, 2008 until maturity. The Company will pay interest semi-annually in arrears on each February 15 and August 15 following the date of issuance of this Note, or if any such day is not a Business Day, on the next succeeding Business Day (each an “Interest Payment Date”). Interest on the Notes will accrue from the most recent date to which interest has been paid or, if no interest has been paid, from the date of issuance; provided that if there is no existing Default in the payment of interest, and if this Note is authenticated between a record date referred to on the face hereof and the next succeeding Interest Payment Date, interest shall accrue from such next succeeding Interest Payment Date; provided, further, that the first Interest Payment Date shall be the Interest Payment Date next following the date set forth in the first sentence of this paragraph. The Company shall pay interest on overdue principal and premium, if any, from time to time as provided in Section 2.12 of the Indenture at the rate borne on the Notes; it shall pay interest on overdue installments of interest (without regard to any applicable grace periods) from time to time as provided in Section 2.12 of the Indenture at the same rate to the extent lawful. Interest will be computed on the basis of a 360-day year of twelve 30-day months.

2. METHOD OF PAYMENT. The Company will pay interest on the Notes (except defaulted interest) to the Persons who are registered Holders of Notes at the close of business on the February 1 or August 1 (whether or not a Business Day) next preceding the Interest Payment Date, even if such Notes are canceled after such record date and on or before such Interest Payment Date, except as provided in Section 2.12 of the Indenture with respect to defaulted interest. The Notes will be payable as to principal, premium, if any, and interest at the office or agency of the Company maintained for such purpose within the City and State of New York, or, at the option of the Company, payment of interest may be made by check mailed to the Holders at their addresses set forth in the register of Holders, and provided that payment by wire transfer of immediately available funds will be required with respect to principal of and interest and premium, if any, on, all Global Notes and all other Notes the Holders of which shall have provided wire transfer instructions to the Company or the Paying Agent. Such payment shall be in such coin or currency of the United States of America as at the time of payment is legal tender for payment of public and private debts.

3. PAYING AGENT AND REGISTRAR. Initially, The Bank of New York Trust Company, N.A., the Trustee under the Indenture, will act as Paying Agent and Registrar. The Company may change any Paying Agent or Registrar without notice to any Holder. The Company or any of its Subsidiaries may act in any such capacity.

A-2

4. INDENTURE. The Company issued the Notes under an Indenture dated as of April 21, 2008 (“Indenture”) between the Company and the Trustee. The terms of the Notes include those stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act of 1939, as amended (15 U.S. Code Sections 77aaa-77bbbb). The Notes are subject to all such terms, and Holders are referred to the Indenture and such Act for a statement of such terms. To the extent any provision of this Note conflicts with the express provisions of the Indenture, the provisions of the Indenture shall govern and be controlling. The Notes are obligations of the Company initially limited to $174,585,000 in aggregate principal amount, but the aggregate principal amount may be increased as provided in the Indenture.

5. OPTIONAL REDEMPTION. The Company may redeem any or all of the Notes at any time on or after August 15, 2010, upon not less than 30 nor more than 60 days’ prior notice in amounts of $1,000 or an integral multiple thereof at the redemption prices (expressed as a percentage of the principal amount) set forth below, if redeemed during the 12-month period beginning August 15 of the years indicated below:

Year	Redemption Price
2010		103.063	%
2011		102.042	%
2012		101.021	%
2013 and thereafter		100.000	%

in each case together with accrued and unpaid interest, if any, to the date of redemption.

     If less than all the Notes are to be redeemed, the Trustee will select the particular Notes or portions thereof to be redeemed or purchased among the Holders of the Notes in compliance with the requirements of the principal national securities exchange, if any, on which the Notes are listed or, if the Notes are not so listed, on a pro rata basis, by lot or in accordance with any other method the Trustee considers fair and appropriate subject to certain restrictions contained in the Indenture.

6. OPTIONAL REDEMPTION UPON EQUITY OFFERING. From time to time, on or prior to August 15, 2008, the Company may, at its option, use the net cash proceeds of one or more Equity Offerings to redeem up to 35% of the aggregate principal amount of the Notes issued under the Indenture at a redemption price equal to 106.125% of the principal amount thereof, plus accrued and unpaid interest thereon, if any, to the date of redemption; provided that (a) at least 65% of the original principal amount of Notes issued under the Indenture shall remain outstanding immediately after any such redemption, and (b) the Company shall make such redemption not more than 90 days after the consummation of any such Equity Offering. If a partial redemption is made with the proceeds of an Equity Offering, selection of the Notes or portions thereof for redemption shall be made by the Trustee only on a pro rata basis or on as nearly a pro rata basis as is practicable (subject to the procedures of the Depositary), unless such method is prohibited.

     As used in the preceding paragraph, “Equity Offering” means any public or private sale of the Company’s Equity Interests (other than Disqualified Stock.)

A-3

7. NOTICE OF REDEMPTION . Notice of redemption shall be mailed at least 30 days but not more than 60 days before any optional redemption date to each Holder whose Notes are to be redeemed at its registered address. Notes and portions of Notes selected shall be in amounts of $1,000 or whole multiples of $1,000; except that if all of the Notes of a Holder are to be redeemed, the entire outstanding amount of Notes held by such Holder, even if not a multiple of $1,000, shall be redeemed. On and after the redemption date interest ceases to accrue on Notes, or portions thereof called for redemption.

8. DENOMINATIONS, TRANSFER, EXCHANGE. The Notes are in registered form without coupons in denominations of $1,000 and integral multiples of $1,000. The transfer of Notes may be registered and Notes may be exchanged as provided in the Indenture. The Registrar and the Trustee may require a Holder, among other things, to furnish appropriate endorsements and transfer documents and the Company may require a Holder to pay any taxes and fees required by law or permitted by the Indenture. The Company need not exchange or register the transfer of any Note or portion of a Note selected for redemption, except for the unredeemed portion of any Note being redeemed in part. Also, it need not exchange or register the transfer of any Notes for a period of 15 days before the mailing of a notice of redemption of Notes to be redeemed or during the period between a record date and the corresponding Interest Payment Date.

9. PERSONS DEEMED OWNERS. The registered Holder of a Note may be treated as its owner for all purposes.

10. AMENDMENT, SUPPLEMENT AND WAIVER. Subject to certain exceptions, the Indenture or the Notes may be amended or supplemented with the consent of the Holders of at least a majority in principal amount of the then outstanding Notes, and any existing default or compliance with any provision of the Indenture or the Notes may be waived with the consent of the Holders of a majority in principal amount of the then outstanding Notes. Without the consent of any Holder of a Note, the Indenture or the Notes may be amended or supplemented to cure any ambiguity, defect or inconsistency, to provide for uncertificated Notes in addition to or in place of certificated Notes or to alter the provisions in Article 2 of the Indenture in a manner that does not materially adversely affect any Holder, to provide for the assumption of the Company’s obligations to Holders of the Notes in case of a merger, consolidation or sale of assets in accordance with Article 5 of the Indenture, to make any change that would provide any additional rights or benefits to the Holders of the Notes or that does not adversely affect the legal rights under the Indenture of any such Holder in any material respect, to comply with the requirements of the SEC in order to effect or maintain the qualification of the Indenture under the TIA, or to allow any guarantor to guarantee the Notes.

11. DEFAULTS AND REMEDIES. Events of Default include: (a) default in the payment when due of principal of the Notes; (b) default in the payment when due of interest on the Notes and such default continues for a period of 30 days; (c) failure by the Company or any of its Restricted Subsidiaries to observe or perform any other covenant (other than the covenants described in (a) and (b) above) in the Indenture or the Notes for 60 days after notice to the Company by the Trustee or the Holders of at least 25% in aggregate principal amount of the Notes then outstanding; (d) failure by the Company or any Subsidiary to pay indebtedness when due within the applicable grace period, if any, or the acceleration of such indebtedness by the

A-4

holders thereof and, in either case, the principal amount of such unpaid or accelerated indebtedness exceeds $20 million; or (e) certain events of bankruptcy or insolvency with respect to the Company or any of its Significant Subsidiaries as specified in Section 6.1 of the Indenture. If any Event of Default occurs and is continuing, the Trustee or the Holders of at least 25% in principal amount of the then outstanding Notes by notice to the Company may declare all the Notes to be due and payable immediately. Notwithstanding the foregoing, in the case of an Event of Default arising from certain events of bankruptcy or insolvency, the principal amount of all then outstanding Notes will become due and payable without further action or notice. Holders may not enforce the Indenture or the Notes except as provided in the Indenture. Subject to certain limitations, Holders of a majority in principal amount of the then outstanding Notes may direct the Trustee in its exercise of any trust or power. The Trustee may withhold from Holders of the Notes notice of any continuing Default or Event of Default (except a Default or Event of Default relating to the payment of principal, premium, if any, or interest) if it determines that withholding notice is in their interest. The Holders of a majority in aggregate principal amount of the Notes then outstanding by notice to the Trustee may on behalf of the Holders of all of the Notes waive any existing Default or Event of Default and its consequences under the Indenture except a continuing Default or Event of Default in the payment of interest or premium, if any, on, or the principal of, the Notes or in respect of any other covenant or provision of the Indenture which, under Section 9.2 of the Indenture, cannot be modified without the consent of the Holder of each outstanding Note. The Company is required to deliver to the Trustee annually a statement regarding compliance with the Indenture, and the Company is required upon becoming aware of any Default or Event of Default, to deliver to the Trustee a statement specifying such Default or Event of Default.

12. TRUSTEE DEALINGS WITH COMPANY. The Trustee, in its individual or any other capacity, may make loans to, accept deposits from, and perform services for the Company or its Affiliates, and may otherwise deal with the Company or its Affiliates, as if it were not the Trustee.

13. NO RECOURSE AGAINST OTHERS. A director, officer, employee, incorporator, partner, member or stockholder of the Company or any Subsidiary of the Company, as such, shall not have any liability for any obligations of the Company under the Notes, or the Indenture or for any claim based on, in respect of, or by reason of, such obligations or their creation. Each Holder by accepting a Note waives and releases all such liability. The waiver and release are part of the consideration for the issuance of the Notes.

14. AUTHENTICATION. This Note shall not be valid until authenticated by the manual signature of an authorized signatory of the Trustee or an authenticating agent.

15. ABBREVIATIONS. Customary abbreviations may be used in the name of a Holder or an assignee, such as: TEN COM (= tenants in common), TEN ENT (= tenants by the entireties), JT TEN (joint tenants with right of survivorship and not as tenants in common), CUST (= Custodian), and U/G/M/A (= Uniform Gifts to Minors Act).

16. CUSIP NUMBERS. Pursuant to a recommendation promulgated by the Committee on Uniform Security Identification Procedures, the Company has caused CUSIP numbers to be printed on the Notes, and CUSIP numbers will be used in notices of redemption as a convenience

However, if on the date such request is made, the Dollar Amount of the sum of the outstanding Revolving Advances and the Letter of Credit Exposure is greater than 50% of the aggregate Revolving Commitments, then (A) promptly after receipt by the applicable Foreign Swingline Lender of any request for a Foreign Swingline Advance, the applicable Foreign Swingline Lender will confirm with the Administrative Agent that the Administrative Agent has also received such request and, if not, the applicable Foreign Swingline Lender will notify the Administrative Agent of the contents thereof, and (B) unless the applicable Foreign Swingline Lender has received notice in writing from the Administrative Agent (including at the request of any Lender) prior to 2:00 p.m. (in the Applicable Time) on the date of the proposed Swingline Advance directing the applicable Foreign Swingline Lender not to make such Swingline Advance as a result of the limitations set forth in the first proviso of Section 2.1(b) above then, subject to the terms and conditions hereof, the applicable foreign Swingline Lender will, not later than 3:00 p.m. (in the Applicable Time) on the borrowing date specified for such Swingline Advance, make the amount of such Swingline Advance available at the Borrower’s account with the Administrative Agent or such other accounts as may be designated by the Borrower.

     (iv) With respect to Swingline Advances denominated in Dollars, each Swingline Lender at any time in its sole and absolute discretion may request, on behalf of the Borrower (which hereby irrevocably authorizes each Swingline Lender to so request on its behalf), that each Lender make a Prime Rate Advance in an amount equal to such Lender’s Pro Rata Share of such Swingline Advances in order to refinance such Swingline Advances. With respect to Foreign Swingline Advances, each Swingline Lender in its sole and absolute discretion may request, on behalf of the Borrower (which hereby irrevocably authorizes each Swingline Lender to so request on its behalf), that each Lender make a Eurocurrency Rate Advance in the same Foreign Currency, in an amount equal to such Lender’s Pro Rata Share of such Swingline Advances and with Interest Period of one month. The applicable Swingline Lender shall give the

19

Administrative Agent notice of such Mandatory Revolving Borrowing (A) by 12:00 p.m. (Houston, Texas time) on the date before the proposed Mandatory Revolving Borrowing is to be made in the case of a Prime Rate Advance and (B) by 12:00 p.m. (Houston, Texas time) on the fourth Business Day before the date of such proposed Mandatory Revolving Borrowing in the case of a Eurocurrency Rate Advance denominated in a Foreign Currency, which notice the Administrative Agent will promptly forward to each Lender. Each Lender shall make its Revolving Advance available to the Administrative Agent for the account of the applicable Swingline Lender in immediately available funds by 2:00 p.m. (Houston, Texas time) on the date requested, and the Borrower hereby irrevocably instructs the applicable Swingline Lender to apply the proceeds of such Mandatory Revolving Borrowing to the payment of the outstanding Swingline Advances.

     (v) If for any reason any Swingline Advance cannot be refinanced by a Revolving Borrowing in accordance with clause (iv) above, the request for the Revolving Advances submitted by the applicable Swingline Lender as set forth therein shall be deemed to be a request by such Swingline Lender that each of the Lenders fund its risk participation in the relevant Swingline Advances and each Lender’s payment to the Administrative Agent for the account of the applicable Swingline Lender pursuant to clause (iv) above shall be deemed payment in respect of such participation.

     (vi) If any Lender fails to make available to the Administrative Agent for the account of the applicable Swingline Lender any amount required to be paid by such Lender pursuant to the foregoing provisions of this Section 2.1(b) by the time specified in this Section 2.1(b), such Swingline Lender shall be entitled to recover from such Lender (acting through the Administrative Agent), on demand, such amount with interest thereon for the period from the date such payment is required to the date on which such payment is immediately available to such Swingline Lender at a rate per annum equal to the applicable Overnight Rate from time to time in effect. A certificate of such Swingline Lender submitted to any Lender (through the Administrative Agent) with respect to any amounts owing under this clause (vi) shall be conclusive absent manifest error.

     (vii) Each Lender’s obligation to make the Revolving Advances or to purchase and fund risk participations in Swingline Advances pursuant to this Section 2.1(b) shall be absolute and unconditional and shall not be affected by any circumstance, including (A) any setoff, counterclaim, recoupment, defense or other right which such Lender may have against any Swingline Lender, the Borrower or any other Person for any reason whatsoever, (B) the occurrence or continuance of a Default, (C) whether or not the conditions precedent in Section 3.2 have been satisfied, (D) termination of the Revolving Commitments or acceleration of the Advances, and (E) any other occurrence, event or condition, whether or not similar to any of the foregoing. No such funding of risk participations shall relieve or otherwise impair the obligation of the Borrower to repay Swingline Advances, together with interest as provided herein.

     (viii) At any time after any Lender has purchased and funded a risk participation in a Swingline Advance, if the applicable Swingline Lender receives any payment on account of such Swingline Advance, such Swingline Lender will distribute to such Lender its Pro Rata Share of such payment (appropriately adjusted, in the case of interest payments, to reflect the period of time during which such Lender’s risk participation was funded) in the same funds as those received by such Swingline Lender.

     (ix) Each Swingline Lender shall be responsible for invoicing the Borrower for interest on the Swingline Advances made by such Swingline Lender. Until a Lender funds its

20

Prime Rate Advance, Eurocurrency Rate Advance or risk participation pursuant to this Section 2.1(b) to refinance such Lender’s Pro Rata Share of any Swingline Advance, interest in respect of such Pro Rata Share shall be solely for the account of the applicable Swingline Lender.

     (x) The Borrower shall make all payments of principal and interest in respect of any Swingline Advances directly to the applicable Swingline Lender.

     (xi) For purposes of calculating outstandings under this Agreement (a) on each March 31, June 30, September 30 and December 31, commencing June 30, 2008, and (b) from time to time as the Administrative Agent may request, each Swingline Lender shall provide the Administrative Agent with a daily log, in form and detail reasonably acceptable to the Administrative Agent, setting forth the outstanding Dollar Amount of the Swingline Advances made by such Swingline Lender using the Exchange Rate as most recently determined by the Administrative Agent.

          Section 2.2 Method of Borrowing.

          (a) Notice. Each Revolving Borrowing shall be made pursuant to a Notice of Borrowing and given:

     (i) by the Borrower to the Administrative Agent not later than 12:00 p.m. (Houston, Texas time) on the fourth Business Day before the date of the proposed Borrowing in the case of a Eurocurrency Rate Advance denominated in a Foreign Currency,

     (ii) by the Borrower to the Administrative Agent not later than 12:00 p.m. (Houston, Texas time) on the third Business Day before the date of the proposed Borrowing in the case of a Eurocurrency Rate Advance denominated in Dollars, and

     (iii) by the Borrower to the Administrative Agent not later than 12:00 p.m. (Houston, Texas time) one Business Day before the date of the proposed Borrowing in the case of a Prime Rate Advance.

The Administrative Agent shall give each Lender prompt notice on the day of receipt of timely Notice of Borrowing of such proposed Borrowing by telecopier. Each Notice of Borrowing shall be by telephone or telecopier, and if by telephone, confirmed promptly in writing (which confirmation may be provided by telecopier or with a “PDF” file delivered in an e-mail with a return acknowledgment requested), specifying the (i) requested date of such Borrowing (which shall be a Business Day), (ii) requested Type of Advances comprising such Borrowing, (iii) aggregate amount of such Borrowing, (iv) if such Borrowing is to be comprised of Eurocurrency Rate Advances, the Interest Period for each such Advance, and (v) the Designated Currency of such Borrowing. In the case of a proposed Borrowing comprised of Eurocurrency Rate Advances, the Administrative Agent shall promptly notify each Lender of the applicable interest rate under Section 2.6(b). Each Lender shall, before 3:00 p.m. (Houston, Texas time) on the date of the proposed Borrowing, make available for the account of its Lending Office to the Administrative Agent at its address referred to in Section 9.2, or such other location as the Administrative Agent may specify by notice to the Lenders, in same day funds, such Lender’s Pro Rata Share of such Borrowing. Promptly upon the Administrative Agent’s receipt of such funds (but in any event not later than 4:00 p.m. (Houston, Texas time) on the date of the proposed Borrowing) and provided that the applicable conditions set forth in Article III have been satisfied, the Administrative Agent will make such funds available to the Borrower at its account with the Administrative Agent.

21

          (b) Conversions and Continuations. In order to elect to Convert or continue Advances comprising part of the same Revolving Borrowing under this Section, the Borrower shall deliver an irrevocable Notice of Conversion or Continuation to the Administrative Agent at the Administrative Agent’s office no later than 12:00 p.m. (Houston, Texas time) (i) at least one Business Day in advance of the proposed conversion date in the case of a Conversion of such Advances to Prime Rate Advances, (ii) at least three Business Days in advance of the proposed Conversion or continuation date in the case of a Conversion to, or a continuation of, Eurocurrency Rate Advances denominated in Dollars; and (iii) at least four Business Days in advance of the proposed Conversion or continuation date in the case of a Conversion to, or a continuation of, Eurocurrency Rate Advances denominated in Foreign Currencies. Each such Notice of Conversion or Continuation shall be by telephone or telecopier, and if by telephone, confirmed promptly in writing (which confirmation may be provided by telecopier or with a “PDF” file delivered in an e-mail with a return acknowledgment requested), specifying (A) the requested Conversion or continuation date (which shall be a Business Day), (B) the Borrowing amount and Type of the Advances to be Converted or continued, (C) whether a Conversion or continuation is requested, and if a Conversion, into what Type of Advances, and (D) in the case of a Conversion to, or a continuation of, Eurocurrency Rate Advances, the requested Interest Period. Promptly after receipt of a Notice of Conversion or Continuation under this paragraph, the Administrative Agent shall provide each Lender with a copy thereof and, in the case of a Conversion to or a continuation of Eurocurrency Rate Advances, notify each Lender of the applicable interest rate under Section 2.6(b). For purposes other than the conditions set forth in Section 3.2, the portion of Revolving Advances comprising part of the same Revolving Borrowing that are Converted to Revolving Advances of another Type shall constitute a new Revolving Borrowing.

          (c) Certain Limitations. Notwithstanding anything herein to the contrary:

     (i) each Borrowing (other than a Borrowing of Swingline Advances) shall (A) in the case of Eurocurrency Rate Advances, be in an aggregate amount not less than $3,000,000 and greater multiples of $1,000,000 in excess thereof, (B) in the case of Prime Rate Advances, be in an aggregate amount not less than $500,000 and greater multiples of $100,000 in excess thereof, and (C) consist of Advances of the same Type made on the same day by the Lenders according to their Pro Rata Share;

     (ii) at no time shall there be more than eight Interest Periods applicable to outstanding Eurocurrency Rate Advances;

     (iii) no single Borrowing consisting of Eurocurrency Rate Advances may include Advances in different currencies;

     (iv) the Borrower may not select Eurocurrency Rate Advances for any Borrowing to be made, Converted or continued if (A) the aggregate Dollar Amount of such Borrowing is less than $3,000,000 or (B) a Default or Event of Default has occurred and is continuing;

     (v) (A) if any Lender shall, at any time prior to the making of any requested Borrowing comprised of Eurocurrency Rate Advances, notify the Administrative Agent that the introduction of or any change in or in the interpretation of any Legal Requirement makes it unlawful, or that any central bank or other Governmental Authority asserts that it is unlawful, for such Lender or its Lending Office to perform its obligations under this Agreement to make Eurocurrency Rate Advances or to fund or maintain Eurocurrency Rate Advances, or any Governmental Authority has imposed material restrictions on the authority of such Lender to purchase or sell, or take deposits of, Dollars or any Foreign Currency in the applicable interbank

22

market, then (1) if the requested Borrowing was of Revolving Advances denominated in Dollars, such Lender’s Pro Rata Share of such Borrowing shall be made as a Prime Rate Advance of such Lender, (2) in any event, such Prime Rate Advance shall be considered part of the same Borrowing and interest on such Prime Rate Advance shall be due and payable at the same time that interest on the Eurocurrency Rate Advances comprising the remainder of such Borrowing shall be due and payable, and (3) any obligation of such Lender to make, continue, or Convert to, Eurocurrency Rate Advances in the affected currency or currencies, including in connection with such requested Borrowing, shall be suspended until such Lender notifies the Administrative Agent and the Borrower that the circumstances giving rise to such determination no longer exist; and (B) such Lender agrees to use commercially reasonable efforts (consistent with its internal policies and legal and regulatory restrictions) to designate a different Lending Office if the making of such designation would avoid the effect of this paragraph and would not, in the reasonable judgment of such Lender, be otherwise disadvantageous to such Lender;

     (vi) if the Administrative Agent is unable to determine the Eurocurrency Rate for Eurocurrency Rate Advances comprising any requested Revolving Borrowing, the right of the Borrower to select Eurocurrency Rate Advances in the affected currency or currencies for such Borrowing or for any subsequent Borrowing shall be suspended until the Administrative Agent shall notify the Borrower and the Lenders that the circumstances causing such suspension no longer exist, and upon receipt by the Borrower of the notice of such suspension, the Borrower may revoke the pending request or, failing that, each Revolving Advance comprising such Borrowing shall be made as a Prime Rate Advance in the Dollar Amount of the originally requested Advance;

     (vii) if the Majority Lenders shall, at least one Business Day before the date of any requested Borrowing, notify the Administrative Agent that (A) the Eurocurrency Rate for Eurocurrency Rate Advances comprising such Borrowing will not adequately reflect the cost to such Lenders of making or funding their respective Eurocurrency Rate Advances, or (B) deposits are not being offered to banks in the applicable offshore interbank market for such currency for the applicable amount and Interest Period of such Eurocurrency Rate Advance, the right of the Borrower to select Eurocurrency Rate Advances in the affected currency or currencies for such Borrowing or for any subsequent Revolving Borrowing shall be suspended until the Administrative Agent shall notify the Borrower and the Lenders that the circumstances causing such suspension no longer exist, and upon receipt by the Borrower of the notice of such suspension, the Borrower may revoke the pending request or, failing that, each Advance comprising such Borrowing shall be made as a Prime Rate Advance in the Dollar Amount of the originally requested Advance;

     (viii) if any Lender shall, at any time prior to the making of any requested Borrowing comprised of Eurocurrency Rate Advances denominated in a Foreign Currency, notify the Administrative Agent that, as a result of internal banking policy limitations on fundings in such Foreign Currency, such Lender can not fund all or any portion of its Pro Rata Share of such Borrowing, then (A) such portion shall be made as a Prime Rate Advance of such Lender, and (B) in any event, such Prime Rate Advance shall be considered part of the same Borrowing and interest on such Prime Rate Advance shall be due and payable at the same time that interest on the Eurocurrency Rate Advances comprising the remainder of such Borrowing shall be due and payable;

     (ix) if the Borrower shall fail to select the duration or continuation of any Interest Period for any Eurocurrency Rate Advance in accordance with the provisions contained in the definition of “Interest Period” in Section 1.1 and paragraph (a) or (b) above, the

23

Administrative Agent will forthwith so notify the Borrower and the Lenders and (A) if denominated in Dollars, such affected Advances will be made available to the Borrower on the date of such Borrowing as Prime Rate Advances or, if such affected Advances are existing Advances, will be Converted into Prime Rate Advances or at the end of Interest Period then in effect, and (B) if denominated in a Foreign Currency, the Borrower shall be deemed to have specified an Interest Period of one month for such affected Advances or, if such affected Advances are existing Advances, such affected Advances will be continued as a Eurocurrency Rate Advance in the original Designated Currency with an Interest Period of one month;

     (x) if the Borrower shall fail to specify a currency for any Eurocurrency Rate Advances, then the Eurocurrency Rate Advances as requested shall be made in Dollars;

     (xi) Revolving Advances may only be Converted or continued as Revolving Advances;

     (xii) Swingline Advances may not be Converted or continued; and

     (xiii) no Revolving Advance may be Converted or continued as a Revolving Advance in a different currency, but instead must be prepaid in the original Designated Currency of such Revolving Advance and reborrowed in such new Designated Currency.

          (d) Notices Irrevocable. Each Notice of Borrowing and Notice of Conversion or Continuation shall be irrevocable and binding on the Borrower.

          (e) Administrative Agent Reliance. Unless the Administrative Agent shall have received notice from a Lender before the date of any Revolving Borrowing or Mandatory Revolving Borrowing that such Lender will not make available to the Administrative Agent such Lender’s Pro Rata Share of such Borrowing, the Administrative Agent may assume that such Lender has made its Pro Rata Share of such Borrowing available to the Administrative Agent on the date of such Borrowing in accordance with paragraph (a) of this Section 2.2 and the Administrative Agent may, in reliance upon such assumption, make available to the Borrower on such date a corresponding amount. If and to the extent that such Lender shall not have so made its Pro Rata Share of such Borrowing available to the Administrative Agent, such Lender and the Borrower severally agree to immediately repay to the Administrative Agent on demand such corresponding amount, together with interest on such amount, for each day from the date such amount is made available to the Borrower until the date such amount is repaid to the Administrative Agent, at (i) in the case of the Borrower, the interest rate applicable on such day to Advances comprising such Borrowing and (ii) in the case of such Lender, the Overnight Rate for such day. If such Lender shall repay to the Administrative Agent such corresponding amount and interest as provided above, such corresponding amount so repaid shall constitute such Lender’s Advance as part of such Borrowing for purposes of this Agreement even though not made on the same day as the other Advances comprising such Borrowing.

          (f) Lender Obligations Several. The failure of any Lender to make the Advance to be made by it as part of any Borrowing shall not relieve any other Lender of its obligation, if any, to make its Advance on the date of such Borrowing. No Lender shall be responsible for the failure of any other Lender to make the Advance to be made by such other Lender on the date of any Borrowing.

          (g) Evidence of Obligations.

     (i) The Advances made by each Lender shall be evidenced by one or more accounts or records maintained by such Lender and by the Administrative Agent in the ordinary

24

course of business. The accounts or records maintained by Administrative Agent and the Lenders shall be conclusive absent manifest error of the amount of the Advances made by such Lenders to the Borrower and the interest and payments thereon. Any failure to so record or any error in doing so shall not, however, limit or otherwise affect the obligation of the Borrower 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 Administrative Agent in respect of such matters, the accounts and records of the Administrative Agent shall control in the absence of manifest error. Upon the request of any Lender to the Borrower made through the Administrative Agent, the Borrower shall execute and deliver to such Lender (through the Administrative Agent) the applicable Note or Notes which shall evidence such Lender’s Advances to the Borrower in addition to such accounts or records. Each Lender may attach schedules to such Notes and endorse thereon the date, Type (if applicable), amount, currency and maturity of its Advances and payments with respect thereto.

     (ii) In addition to the accounts and records referred to in subsection (i) above, each Lender and the Administrative Agent shall maintain in accordance with its usual practice accounts or records evidencing the purchases and sales by such Lender of participations in Letters of Credit and Swingline Advances. In the event of any conflict between the accounts and records maintained by the Administrative Agent and the accounts and records of any Lender in respect of such matters, the accounts and records of the Administrative Agent shall control in the absence of manifest error.

          Section 2.3 Fees.

          (a) Facility Fees. The Borrower agrees to pay to the Administrative Agent for the account of each Lender, a daily facility fee (the “Facility Fee”) on the amount of such Lender’s Revolving Commitment at a per annum rate equal to the Applicable Margin for facility fees for the period from the Closing Date until the Maturity Date, such fees due and payable quarterly in arrears on the tenth (10^th) day after the end of each March, June, September and December, commencing June 30, 2008, and on the Maturity Date.

          (b) Utilization Fees. Borrower agrees to pay to the Administrative Agent for the account of each Lender a daily utilization fee (the “Utilization Fee”) on the Dollar Amount of the sum of such Lender’s outstanding Revolving Advances and Pro Rata Share of the Letter of Credit Exposure at a per annum rate equal to the Applicable Margin for Utilization Fees, from the Closing Date until the Maturity Date, such fees are (i) calculated quarterly in arrears for the period ending on the last day of each March, June, September and December, commencing June 30, 2008 and due and payable on the immediately following 10^th Business Day, and (ii) calculated in arrears and ending on, and due and payable on, the Maturity Date; provided that the Utilization Fee shall be payable only in respect of each day that the Dollar Amount of the Combined Aggregate Exposure exceeds 50% of the Combined Aggregate Commitments. For purposes of calculating such Utilization Fee, outstandings for Eurocurrency Rate Advances denominated in Foreign Currencies and Letter of Credit Exposure for Letters of Credit denominated in Foreign Currencies shall be converted to their Dollar Amounts on each date that such Utilization Fee is due hereunder using the then effective Exchange Rate.

          (c) Letter of Credit Fees. The Borrower agrees to pay to the Administrative Agent for the pro rata benefit of the Lenders letter of credit fees in respect of all Letters of Credit outstanding at a rate per annum equal to the Applicable Margin for Eurocurrency Rate Advances calculated on the maximum amount available from time to time to be drawn under such outstanding Letters of Credit. All such letter of credit fees shall be (i) calculated quarterly in arrears for the period ending on the last day of each March, June, September and December, commencing June 30, 2008 and due and payable on the

25

immediately following 10^th Business Day, and (ii) calculated in arrears and ending on, and due and payable on, the Maturity Date. In addition, the Borrower agrees to pay to each Issuing Lender for its own account fronting fees in respect of all Letters of Credit outstanding and issued by such Issuing Lender equal to the greater of (A) one-eighth percent (1/8%) per annum of the maximum amount available from time to time to be drawn under such outstanding Letters of Credit and (B) $500, payable at issuance and on the earlier of each annual anniversary thereafter or the Maturity Date. The Borrower shall also pay to each Issuing Lender for its own account such documentary, processing and other charges in connection with the issuance, amendment, transfer, modification of and draws under Letters of Credit assessed or incurred by such Issuing Lender from time to time. For purposes of calculating the letter of credit fees, fronting fees and other fees under this Section 2.3(c), the face amount of each Letter of Credit made in a Foreign Currency shall be at any time the Dollar Amount of such Letter of Credit as determined on the most recent Computation Date with respect to such Letter of Credit.

          (d) Administrative Agent Fees. The Borrower agrees to pay when due to the Administrative Agent for its benefit the fees set forth in the Agent’s Fee Letter.

     Section 2.4 Reduction of Commitments. The Borrower shall have the right, upon at least three Business Days’ irrevocable notice to the Administrative Agent and the Lenders, to terminate in whole or reduce ratably in part the unused portion of the Revolving Commitments; provided that, each partial reduction shall be in the aggregate amount of $3,000,000 or an integral multiple of $1,000,000 in excess thereof. Any reduction or termination of the Revolving Commitments pursuant to this Section 2.4 shall be permanent, with no obligation of the Lenders to reinstate such Revolving Commitments and the commitment fees provided for in Section 2.3(a) shall thereafter be computed on the basis of the Revolving Commitments, as so reduced.

     Section 2.5 Repayment of Advances.

          (a) Revolving Advances. The Borrower shall repay the outstanding principal amount of each Revolving Advance on the Maturity Date and, for each Mandatory Revolving Borrowing made on or after the Maturity Date, on demand, and in any event, in the Designated Currency in which each such Advance was funded.

          (b) Swingline Advances. The Borrower shall repay the outstanding principal amount of each Swingline Advance on the earlier of (i) the Swingline Due Date immediately following the date such Swingline Advance is made by the applicable Swingline Lender and (ii) the Maturity Date.

     Section 2.6 Interest. The Borrower shall pay interest on the unpaid principal amount of each Advance from the date of such Advance until such principal amount shall be paid in full, at the following rates per annum:

          (a) Prime Rate Advances. If such Advance is a Prime Rate Advance, a rate per annum equal at all times to the lesser of (i) the Adjusted Prime Rate in effect from time to time plus the Applicable Margin and (ii) the Maximum Rate, payable in arrears on the last Business Day of each calendar quarter, commencing with the calendar quarter ending June 30, 2008, and on the date such Prime Rate Advance shall be paid in full, provided that if any payment of principal on any Advance is not made when due, such Advances shall bear interest from the date such payment was due until such Advances are paid in full, payable on demand, at a rate per annum equal at all times to the lesser of (A) the rate required to be paid on such Advance immediately prior to the date on which such amount becomes due plus two percent (2%) and (B) the Maximum Rate.

26

          (b) Eurocurrency Rate Advances. If such Advance is a Eurocurrency Rate Advance, during the Interest Period for such Advance, a rate per annum equal at all times to the lesser of (i) the Eurocurrency Rate for such Interest Period plus the Applicable Margin plus (in the case of a Eurocurrency Rate Advance of any Lender which is lent from a Lending Office in the United Kingdom or a Participating Member State) the Mandatory Cost Rate and (ii) the Maximum Rate, payable in arrears on the last day of such Interest Period (provided that for Eurocurrency Rate Advance with six month Interest Periods, accrued but unpaid interest shall also be due on the day three months from the first day of such Interest Period), and on the date such Eurocurrency Rate Advance shall be paid in full; provided that if any payment of principal on any Advance is not made when due, such Advances shall bear interest from the date such payment was due until such Advances are paid in full, payable on demand, at a rate per annum equal at all times to the lesser of (A) the greater of (1) the Adjusted Prime Rate in effect from time to time plus two percent (2%) and (2) the rate required to be paid on such Advance immediately prior to the date on which such amount became due (including the Applicable Margin and any Mandatory Cost Rate) plus two percent (2%) and (B) the Maximum Rate.

          (c) Swingline Advances. If such Advance is a Swingline Advance, a rate per annum equal at all times to the lesser of (i) the Swingline Rate for such Swingline Advance and (ii) the Maximum Rate, payable quarterly in arrears on the last Business Day of each calendar quarter, commencing with the calendar quarter ending June 30, 2008, and on the Maturity Date; provided that if any payment of principal on any Advance is not made when due, such Advances shall bear interest from the date such payment was due until such Advances are paid in full, at a rate per annum equal at all times to the lesser of (A) the rate required to be paid on such Advance immediately prior to the date on which such amount becomes due plus two percent (2%) and (B) the Maximum Rate.

          (d) Usury Recapture. As to each Lender, in the event the rate of interest chargeable under this Agreement or the Notes at any time is greater than the Maximum Rate, the unpaid principal amount of Obligations owing to such Lender shall bear interest at the Maximum Rate until the total amount of interest paid or accrued on such Obligations equals the amount of interest which would have been paid or accrued on such Obligations if the stated rates of interest set forth in this Agreement had at all times been in effect. In the event, upon payment in full of such Obligations, the total amount of interest paid or accrued under the terms of this Agreement and the Notes as to any Lender is less than the total amount of interest which would have been paid or accrued if the rates of interest set forth in this Agreement had, at all times, been in effect, then the Borrower shall, to the extent permitted by applicable Legal Requirements, pay the Administrative Agent for the account of such Lenders an amount equal to the difference between (i) the lesser of (A) the amount of interest which would have been charged on Obligations owing to such Lender if the Maximum Rate had, at all times, been in effect and (B) the amount of interest which would have accrued on such Obligations if the rates of interest set forth in this Agreement had at all times been in effect and (ii) the amount of interest actually paid or accrued under this Agreement on such Obligations. In the event any Lender ever receives, collects or applies as interest any sum in excess of the Maximum Rate, such excess amount shall, to the extent permitted by law, be applied to the reduction of the principal balance of the Obligations owing to it, and if no such principal is then outstanding, such excess or part thereof remaining shall be paid to the Borrower.

          (e) Other Amounts Overdue. If any amount payable under this Agreement other than the Advances is not paid when due and payable, including accrued interest and fees, then such overdue amount shall accrue interest hereon due and payable on demand (i) if such amount is in Dollars, at a rate per annum equal to the lesser of (A) Adjusted Prime Rate plus two percent (2%) and (B) the Maximum Rate, from the date such amount became due until the date such amount is paid in full, and (ii) if such amount is in a Foreign Currency, the lesser of (A) the greater of (1) the Adjusted Prime Rate in effect from time to time plus two percent (2%) and (2) the overnight Eurocurrency Rate plus the Applicable Margin and any Mandatory Cost Rate for Eurocurrency Rate Advances plus two percent (2%) and (B) the Maximum Rate.

27

     Section 2.7 Prepayments.

          (a) Right to Prepay. The Borrower shall have no right to prepay any principal amount of any Advance except as provided in this Section 2.7.

          (b) Optional Prepayments. The Borrower may elect to prepay any of the Advances, after giving notice thereof to the Administrative Agent and the Lenders by 12:00 p.m. (Houston, Texas) for Advances denominated in Dollars and by 12:00 p.m. in the Applicable Time for Revolving Advances denominated in Foreign Currencies and Swingline Advances made by Foreign Swingline Lenders (i) on the day of prepayment of any Swingline Advance, (ii) at least three Business Days’ prior to the day of prepayment of any Eurocurrency Rate Advances and (iii) the day prior to the prepayment of any Prime Rate Advance. Such notice shall be by telephone or telecopier, and if by telephone, confirmed promptly in writing, and must state the proposed date and aggregate principal amount of such prepayment, whether such prepayment should be applied to reduce outstanding Revolving Advances or Swingline Advances, and if applicable, the relevant Interest Period for the Advances to be prepaid. If any such notice is given, the Borrower shall prepay Advances comprising part of the same Borrowing in whole or ratably in part in an aggregate principal amount equal to the amount specified in such notice, and shall also pay accrued interest to the date of such prepayment on the principal amount prepaid and amounts, if any, required to be paid pursuant to Section 2.8 as a result of such prepayment being made on such date; provided, however, that (i) each partial prepayment of Eurocurrency Rate Advances shall be in an aggregate principal amount of not less than $3,000,000 and in integral multiples of $1,000,000 in excess thereof, (ii) each partial prepayment of Prime Rate Advances shall be in an aggregate principal amount of not less than $500,000 and in integral multiples of $100,000 in excess thereof, (iii) each partial prepayment of Swingline Advances shall be in an aggregate principal amount of not less than $500,000, and (iv) any prepayment of an Advance shall be made in the Designated Currency in which such Advance was funded. Each prepayment pursuant to this Section 2.7(b) shall be accompanied by accrued interest on the amount prepaid to the date of such prepayment and amounts, if any, required to be paid pursuant to Section 2.8 as a result of such prepayment being made on such date.

          (c) Ratable Payments. Each payment of any Advance pursuant to this Section 2.7 or any other provision of this Agreement shall be made in a manner such that all Advances comprising part of the same Borrowing are paid in whole or ratably in part.

          (d) Effect of Notice. All notices given pursuant to this Section 2.7 shall be irrevocable and binding upon the Borrower.

     Section 2.8 Breakage Costs. If (a) any payment of principal of any Eurocurrency Rate Advance is made other than on the last day of the Interest Period for such Advance as a result of any payment hereunder or the acceleration of the maturity of the Obligations pursuant to Article VIII or otherwise; (b) the Borrower fails to borrow, Convert, continue, repay or prepay any Eurocurrency Rate Advance on the date specified in any notice delivered pursuant hereto (other than default by a Lender), (c) the Borrower fails to make a principal or interest payment with respect to any Eurocurrency Rate Advance on the date such payment is due and payable, the Borrower shall, within 10 days of any written demand sent by any Lender to the Borrower (with a copy to the Administrative Agent), pay to the Administrative Agent for the account of such Lender any amounts (without duplication of any other amounts payable in respect of breakage costs) required to compensate such Lender for any additional losses, out-of-pocket costs or expenses which it may reasonably incur as a result of such payment or nonpayment, including any loss (including loss of anticipated profits), cost or expense incurred by reason of the liquidation or reemployment of deposits or other funds acquired by any Lender to fund or maintain such Advance.

28

     Section 2.9 Increased Costs.

          (a) Eurocurrency Rate Advances. If, due to either (i) introduction of or any change in or in the interpretation of any Legal Requirement (other than any change by way of imposition or increase of reserve requirements included in the calculation of the Eurocurrency Rate but including any change or introduction which would result in the failure of the Mandatory Cost Rate, as calculated hereunder, to represent the cost to any Lender of complying with the requirements of the Bank of England and/or the Financial Services Authority or the European Central Bank in relation to its making, funding or maintaining Eurocurrency Rate Advances), or (ii) compliance with any guideline or request from any central bank or other Governmental Authority (whether or not having the force of law), a Lender incurs increase cost related to the making or maintaining Eurocurrency Rate Advances (or maintaining its obligation to make any Eurocurrency Rate Advances), or the amount of any sum received or receivable by such Lender hereunder is reduced (whether of principal, interest or any other amount), then the Borrower shall from time to time, upon demand by such Lender (with a copy of such demand to the Administrative Agent), promptly pay to the Administrative Agent for the account of such Lender additional amounts (without duplication of any other amounts payable in respect of increased costs) sufficient to compensate such Lender for such increased cost or reduction; provided, however, that, before making any such demand, each Lender agrees to use commercially reasonable efforts (consistent with its internal policy and legal and regulatory restrictions) to designate a different Lending Office if the making of such a designation would avoid the need for, or reduce the amount of, such increased cost and would not, in the reasonable judgment of such Lender, be otherwise disadvantageous to such Lender. A certificate as to the amount of such increased cost and detailing the calculation of such cost submitted to the Borrower and the Administrative Agent by such Lender at the time such Lender demands payment under this Section shall be conclusive and binding for all purposes, absent manifest error.

          (b) Capital Adequacy. If any Lender or Issuing Lender determines in good faith that compliance with any Legal Requirement or any guideline or request from any central bank or other Governmental Authority (whether or not having the force of law) implemented or effective after the date of this Agreement affects or would affect the amount of capital required or expected to be maintained by such Lender or Issuing Lender and that the amount of such capital is increased by or based upon the existence of Advances made by such Lender, the existence of Letters of Credit issued or participated in by such Lender or Issuing Lender, the existence of such Lender’s commitment to lend or Issuing Lender’s commitment to issue Letters of Credit or any Lender’s commitment to risk participate in Letters of Credit and other commitments of this type, then, upon 30 days prior written notice by such Lender or Issuing Lender (with a copy of any such demand to the Administrative Agent), the Borrower shall promptly pay to the Administrative Agent for the account of such Lender or to Issuing Lender, as the case may be, from time to time as specified by such Lender or Issuing Lender, additional amounts (without duplication of any other amounts payable in respect of increased costs) sufficient to compensate such Lender or Issuing Lender, in light of such circumstances, (i) with respect to such Lender, to the extent that such Lender reasonably determines such increase in capital to be allocable to the existence of such Lender’s commitment to lend under this Agreement or its commitment to risk participate in Letters of Credit or its having made Advances or participated in Letters of Credit and (ii) with respect to such Issuing Lender, to the extent that such Issuing Lender reasonably determines such increase in capital to be allocable to its commitment to issue or to the issuance or maintenance of the Letters of Credit. A certificate as to such amounts and detailing the calculation of such amounts submitted to the Borrower by such Lender or Issuing Lender shall be conclusive and binding for all purposes, absent manifest error.

29

          (c) Letters of Credit. If any change in any Legal Requirement or in the interpretation thereof by any court or administrative or Governmental Authority charged with the administration thereof shall either (i) impose, modify, or deem applicable any reserve, special deposit, or similar requirement against letters of credit issued by or risk participated in by, or assets held by, or deposits in or for the account of, any Issuing Lender or any Lender or (ii) impose on any Issuing Lender or any Lender any other condition regarding the provisions of this Agreement relating to the Letters of Credit or any Letter of Credit Obligations, and the result of any event referred to in the preceding clause (i) or (ii) shall be to increase the cost to any Issuing Lender of issuing or maintaining any Letter of Credit, or increase the cost to such Lender of its risk participation in any Letter of Credit (which increase in cost shall be determined by such Issuing Lender’s or such Lender’s reasonable allocation of the aggregate of such cost increases resulting from such event), then, upon demand by such Issuing Lender or such Lender (with a copy sent to the Administrative Agent), as the case may be, the Borrower shall pay to the Administrative Agent (for the account of such Issuing Lender or Lender), as the case may be, from time to time as specified by such Issuing Lender or such Lender, additional amounts which shall be sufficient to compensate such Issuing Lender or such Lender for such increased cost. Each Issuing Lender and each Lender agrees to use commercially reasonable efforts (consistent with internal policy and legal and regulatory restrictions) to designate a different Lending Office for the booking of its Letters of Credit or risk participations if the making of such designation would avoid the effect of this paragraph and would not, in the reasonable judgment of such Issuing Lender or such Lender, be otherwise disadvantageous to such Issuing Lender or such Lender, as the case may be. A certificate as to such increased cost incurred by such Issuing Lender or such Lender, as the case may be, as a result of any event mentioned in clause (i) or (ii) above, and detailing the calculation of such increased costs submitted by such Issuing Lender or such Lender to the Borrower, shall be conclusive and binding for all purposes, absent manifest error.

     Section 2.10 Payments and Computations.

          (a) Payment Procedures. Except if otherwise set forth herein, the Borrower shall make each payment under this Agreement not later than 1:00 p.m. (Houston, Texas time) for payments due in Dollars and not later than 1:00 p.m. in the Applicable Time for payments due in Foreign Currencies (and payments due to Foreign Swingline Lenders related to Foreign Swingline Advances), on the day when due in the Designated Currency as to outstanding Advances and Reimbursement Obligations, and in Dollars as to all other amounts, to the Administrative Agent at its Lending Office (or such other location as the Administrative Agent shall designate in writing to the Borrower) in same day funds. The Administrative Agent will promptly thereafter cause to be distributed like funds relating to the payment of principal, interest or fees ratably (other than amounts payable solely to the Administrative Agent, the Issuing Lenders, or a specific Lender pursuant to Section 2.1(b), 2.3(c), 2.3(d), 2.6(d), 2.6(e), 2.8, 2.9, 2.11, 2.12, 2.13(d), 9.4 or 9.7 but after taking into account payments effected pursuant to Section 7.6) to the Lenders in accordance with each Lender’s Pro Rata Share for the account of their respective Lending Offices, and like funds relating to the payment of any other amount payable to any Lender or any Issuing Lender to such Lender or such Issuing Lender for the account of its Lending Office, in each case to be applied in accordance with the terms of this Agreement.

          (b) Computations. All computations of interest based on the Adjusted Prime Rate, interest on Swingline Advances and interest on Eurocurrency Rate Advances denominated in Pounds Sterling shall be made by the Administrative Agent (or with respect to each Swingline Advance, by the applicable Swingline Lender) on the basis of a year of 365 or 366 days, as the case may be. All computations of fees and interest based on the Eurocurrency Rate (other than as set forth in the immediately preceding sentence), Overnight Rate and the Federal Funds Rate shall be made by the Administrative Agent on the basis of a year of 360 days. In any case, such computations shall be made for the actual number of days (including the first day, but excluding the last day) occurring in the period

30

for which such interest or fees are payable. Each determination by the Administrative Agent (or with respect to each Swingline Advance, by the applicable Swingline Lender) of an interest rate shall be conclusive and binding for all purposes, absent manifest error.

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

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

          (e) Application of Payments. Whenever any payment received by the Administrative Agent under this Agreement is insufficient to pay in full all amounts then due and payable under this Agreement and Notes, such payment shall be distributed and applied by the Administrative Agent and the Lenders in the following order: first, to the payment of fees and expenses due and payable to the Administrative Agent under and in connection with this Agreement or any other Credit Document; second, to the payment of all amounts due and payable under Section 2.11(c), ratably among the Lenders in accordance with the aggregate amount of such payments owed to each such Lender; third, to the payment of fees due and payable pursuant to Section 2.3(c), ratably among the Issuing Lenders in accordance with the aggregate amount of such payments owed to each such Issuing Lender; fourth, to the payment of all other fees due and payable under Section 2.3 ratably among the Lenders in accordance with their applicable Revolving Commitments; and fifth, to the payment of the interest accrued on and the principal amount of all of the Advances, and the interest accrued on and the principal amount of all Reimbursement Obligations, regardless of whether any such amount is then due and payable, ratably among the Lenders in accordance with the aggregate accrued interest plus the aggregate principal amount owed to such Lender.

     Section 2.11 Taxes.

          (a) No Deduction for Certain Taxes. Any and all payments by the Borrower shall be made, in accordance with Section 2.10, free and clear of and without deduction for any and all present or future taxes, levies, imposts, deductions, charges or withholdings, and all liabilities with respect thereto, excluding, in the case of each Lender, each Issuing Lender, and the Administrative Agent, taxes imposed on its net income, and franchise taxes imposed on it in lieu thereof, by the jurisdiction under the laws of which such Lender, such Issuing Lender, or the Administrative Agent (as the case may be) is organized or any political subdivision of the jurisdiction (all such non-excluded taxes, levies, imposts, deductions, charges, withholdings and liabilities being hereinafter referred to as “Taxes”) and, in the case of each Lender and each Issuing Lender, Taxes by the jurisdiction of such Lender’s Lending Office or any political subdivision of such jurisdiction. If the Borrower shall be required by law to deduct any Taxes from or in respect of any sum payable to any Lender, any Issuing Lender, or the Administrative Agent, (i)

31

the sum payable shall be increased as may be necessary so that, after making all required deductions (including deductions applicable to additional sums payable under this Section 2.11), such Lender, such Issuing Lender, or the Administrative Agent (as the case may be) receives an amount equal to the sum it would have received had no such deductions been made; provided, however, that if the Borrower’s obligation to deduct Taxes is caused solely by such Lender’s, such Issuing Lender’s, or the Administrative Agent’s failure to provide the forms described in paragraph (e) of this Section 2.11 and such Lender, such Issuing Lender, or the Administrative Agent could have lawfully provided such forms, no such increase shall be required; (ii) the Borrower shall make such deductions; and (iii) the Borrower shall pay the full amount deducted to the relevant taxation authority or other authority in accordance with applicable Legal Requirements.

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

          (c) Indemnification. The Borrower hereby indemnifies each Lender, each Issuing Lender, and the Administrative Agent for the full amount of Taxes or Other Taxes (including any Taxes or Other Taxes imposed by any jurisdiction on amounts payable under this Section 2.11) paid by such Lender, such Issuing Lender, or the Administrative Agent (as the case may be) and any liability (including interest and expenses) arising therefrom or with respect thereto, whether or not such Taxes or Other Taxes were correctly or legally asserted. Each payment required to be made by the Borrower in respect of this indemnification shall be made to the Administrative Agent for the benefit of any party claiming such indemnification within 30 days from the date the Borrower receives written demand detailing the calculation of such amounts therefor from the Administrative Agent, any such Issuing Lender, or any such Lender (with a copy of such demand to the Administrative Agent).

          (d) Evidence of Tax Payments. The Borrower will pay prior to delinquency all Taxes payable in respect of any payment. Within 30 days after the date of any payment of Taxes, the Borrower will furnish to the Administrative Agent, at its address referred to in Section 9.2, the original or a certified copy of a receipt evidencing payment of such Taxes.

          (e) Status of Lenders.

     (i) Any Foreign Lender that is entitled to an exemption from or reduction of withholding tax under the law of the jurisdiction in which the Borrower is resident for tax purposes, or any treaty to which such jurisdiction is a party, with respect to payments hereunder or under any other Credit Document shall deliver to the Borrower (with a copy to the Administrative Agent), at the time or times prescribed by Legal Requirements applicable to such Lender or as reasonably requested by the Borrower or the Administrative Agent, such properly completed and executed documentation prescribed by Legal Requirements which such Lender is lawfully permitted to deliver as will permit such payments to be made without withholding or at a reduced rate of withholding. In addition, any Lender, if requested by the Borrower or Administrative Agent, shall deliver such other documentation prescribed by applicable law or reasonably requested by the Borrower or the Administrative Agent as will enable the Borrower or the Administrative Agent to determine whether or not such Lender is subject to backup withholding or information reporting requirements.

     (ii) Without limiting the generality of the foregoing, in the event that the Borrower is resident for tax purposes in the United States, any Foreign Lender shall deliver to Borrower and the Administrative Agent (in such number of copies as shall be requested by the

32

recipient) on or prior to the date on which such Foreign Lender becomes a Lender under this Agreement (and from time to time thereafter promptly following the request of the Borrower or the Administrative Agent, but only if such Foreign Lender is legally entitled to do so), whichever of the following is applicable:

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

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

(C) in the case of a Foreign Lender claiming the benefits of the exemption for portfolio interest under section 881(c) of the Code, (x) a certificate to the effect that such Foreign Lender is not (A) a “bank” within the meaning of section 881(c)(3)(A) of the Code, (B) a “10 percent shareholder” of the applicable Borrower within the meaning of section 881(c)(3)(B) of the Code, or (C) a “controlled foreign corporation” described in section 881(c)(3)(C) of the Code and (y) duly completed copies of Internal Revenue Service Form W-8BEN, or

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

          (iii) Without limiting the obligations of the Lenders set forth above regarding delivery of certain forms and documents to establish each Lender’s status for U.S. withholding tax purposes, each Lender agrees promptly to deliver to the Administrative Agent or the Borrower, as the Administrative Agent or the Borrower shall reasonably request, on or prior to the Closing Date, and in a timely fashion thereafter following such reasonable request therefor, such other documents and forms required by any relevant taxing authorities under the Legal Requirements of any other jurisdiction, duly executed and completed by such Lender, as are required under such Legal Requirements to confirm such Lender’s entitlement to any available exemption from, or reduction of, applicable withholding taxes in respect of all payments to be made to such Lender outside of the United States by the Borrower pursuant to this Agreement or otherwise to establish such Lender’s status for withholding tax purposes in such other jurisdiction. Each Lender shall promptly notify the Administrative Agent of any change in circumstances which would modify or render invalid any such claimed exemption or reduction. Additionally, the Borrower shall promptly deliver to the Administrative Agent or any Lender, as the Administrative Agent or such Lender shall reasonably request, on or prior to the Closing Date, and in a timely fashion thereafter, such documents and forms required by any relevant taxing authorities under the Legal Requirements of any jurisdiction, duly executed and completed by the Borrower, as are required to be furnished by such Lender or the Administrative Agent under such Legal Requirements in connection with any payment by the Administrative Agent or any Lender of Taxes or Other Taxes, or otherwise in connection with the Credit Documents, with respect to such jurisdiction.

          (f) Treatment of Certain Refunds. If the Administrative Agent, a Lender or an Issuing Lender determines, in its sole discretion, that it has received a refund of any Taxes or Other Taxes as to which it has been indemnified by the Borrower or with respect to which the Borrower has paid additional amounts pursuant to this Section, it shall pay to the Borrower an amount equal to such refund (but only to the extent of indemnity payments made, or additional amounts paid, by the Borrower under this Section with respect to the Taxes or Other Taxes giving rise to such refund), net of all out-of-pocket

33

expenses of the Administrative Agent, such Lender or such Issuing Lender, as the case may be, and without interest (other than any interest paid by the relevant Governmental Authority with respect to such refund), provided that the Borrower, upon the request of the Administrative Agent, such Lender or such Issuing Lender, agrees to repay the amount paid over to the Borrower (plus any penalties, interest or other charges imposed by the relevant Governmental Authority) to the Administrative Agent, such Lender or such Issuing Lender in the event the Administrative Agent, such Lender or such Issuing Lender is required to repay such refund to such Governmental Authority. This paragraph shall not be construed to require the Administrative Agent, any Lender or any Issuing Lender to make available its tax returns (or any other information relating to its taxes that it deems confidential) to the Borrower or any other Person.

          (g) Mitigation. Each Lender agrees to use commercially reasonable efforts (consistent with its internal policies and legal and regulatory restrictions) to select a jurisdiction for its Lending Office or change the jurisdiction of its Lending Office, as the case may be, so as to avoid the imposition of any Taxes or Other Taxes or to eliminate or reduce the payment of any additional sums under this Section 2.11 or to eliminate or reduce the payment of interest due to it which is based on the Mandatory Cost Rate; provided, that no such selection or change of jurisdiction for its Lending Office shall be made if, in the reasonable judgment of such Lender, such selection or change would be disadvantageous to such Lender.

     Section 2.12 Illegality. If any Lender shall notify the Administrative Agent and the Borrower that the introduction of or any change in or in the interpretation of any Legal Requirement makes it unlawful, or that any central bank or other Governmental Authority asserts that it is unlawful for such Lender or its Lending Office to perform its obligations under this Agreement to maintain any Eurocurrency Rate Advances of such Lender then outstanding hereunder or any Governmental Authority has imposed material restrictions on the authority of such Lender to purchase or sell, or take deposits of, Dollars or any Foreign Currency in the applicable interbank market, then, notwithstanding anything herein to the contrary, the Borrower shall, if demanded by such Lender in its notice, no later than 12:00 p.m. (Houston, Texas time), (a) if not prohibited by any Legal Requirement to maintain such Eurocurrency Rate Advances for the duration of the Interest Period, on the last day of the Interest Period for each outstanding Eurocurrency Rate Advance of such Lender or (b) if prohibited by any Legal Requirement to maintain such Eurocurrency Rate Advances for the duration of the Interest Period, on the second Business Day following its receipt of such notice from such Lender, then (i) with respect to Revolving Advances denominated in a Foreign Currency, prepay such Eurocurrency Rate Advances of such Lender then outstanding and which are denominated in such affected currency or currencies together with all accrued interest on the amount so prepaid, and amounts, if any, required to be paid pursuant to Section 2.8 as a result of such prepayment being made on such date, and (ii) with respect to Revolving Advances denominated in Dollars, Convert all such Eurocurrency Rate Advances of such Lender then outstanding to Prime Rate Advances and pay accrued interest on the principal amount Converted to the date of such Conversion and amounts, if any, required to be paid pursuant to Section 2.8 as a result of such Conversion being made on such date. Each Lender agrees to use commercially reasonable efforts (consistent with its internal policies and legal and regulatory restrictions) to designate a different Lending Office if the making of such designation would avoid the effect of this paragraph and would not, in the reasonable judgment of such Lender, be otherwise disadvantageous to such Lender.

     Section 2.13 Letters of Credit.

          (a) Issuance of Letters of Credit. Each Issuing Lender, the Lenders and the Borrower agree that effective as of the Closing Date, the Existing Letters of Credit shall be deemed to have been issued and maintained under, and to be governed by the terms and conditions of, this Agreement as Letters of Credit. From time to time from the date of this Agreement until ten days before the Maturity Date, at the written request of the Borrower given to the applicable Issuing Lender and to the

34

Administrative Agent not later than (i) 12:00 p.m. (Houston, Texas time) on the third Business Day before the date of the proposed issuance, amendment, or extension of a Letter of Credit denominated in a Foreign Currency and (ii) 12:00 p.m. (Houston, Texas time) on the second Business Day (or such later time and date as may be agreed to among the Borrower, the applicable Issuing Lender and the Administrative Agent) before the date of the proposed issuance, amendment, or extension of a Letter of Credit denominated in Dollars, the requested Issuing Lender shall, on any Business Day and on the terms and conditions hereinafter set forth (and, if applicable, subject to the terms of the applicable Letter of Credit), issue, increase, decrease, amend, or extend the expiration date of, Letters of Credit for the account of the Borrower (for its own benefit or for the benefit of any of its Subsidiaries). Promptly after receipt by the applicable Issuing Lender of such request, the applicable Issuing Lender will confirm with the Administrative Agent that the Administrative Agent has also received such request and, if not, the applicable Issuing Lender will notify the Administrative Agent of the contents thereof. With respect to any issuance of or increase to a Letter of Credit, unless the applicable Issuing Lender has received notice in writing from the Administrative Agent (including at the request of any Lender) at least one Business Day prior to the requested date of the proposed issuance or increase, directing the applicable Issuing Lender not to issue or increase such Letter of Credit as a result of the limitations set forth clause 2.13(b)(i) below then, subject to the terms and conditions hereof, the applicable Issuing Lender will issue or increase such Letter of Credit as requested by the Borrower. Letters of Credit shall be denominated in any Agreed Currency.

          (b) Limitations. No Letter of Credit will be issued (or deemed issued as to the Existing Letters of Credit), increased, or extended (i) if such issuance, increase, or extension would cause the sum of the Letter of Credit Exposure plus the aggregate Dollar Amount of all outstanding Revolving Advances and Swingline Advances at such time to exceed the aggregate Revolving Commitments; (ii) unless such Letter of Credit has an Expiration Date not later than the earlier of (A) sixty months after the date of issuance thereof and (B) twenty-four months after the Maturity Date; (iii) unless such Letter of Credit (or, if applicable, the amendment to a Letter of Credit) is in form and substance acceptable to the applicable Issuing Lender in its sole discretion; (iv) unless the Borrower has delivered to the applicable Issuing Lender a completed and executed letter of credit application on such Issuing Lender’s standard form, which shall contain terms no more restrictive than the terms of this Agreement; (v) unless such Letter of Credit is governed by the Uniform Customs and Practice for Documentary Credits (2007 Revision), International Chamber of Commerce Publication No. 600 (“UCP”), the International Standby Practices (ISP 98), International Chamber of Commerce Publication No. 590 (“ISP”) or any successor to the UCP or ISP and, to the extent not inconsistent therewith, the New York Uniform Commercial Code, as in effect from time to time; (vi) if any order, judgment or decree of any Governmental Authority or arbitrator shall by its terms purport to enjoin or restrain an Issuing Lender from issuing or providing such Letter of Credit, or any Legal Requirements applicable to such Issuing Lender shall prohibit the issuance or provision of such type of Letter of Credit generally or such Letter of Credit in particular or shall impose upon such Issuing Lender with respect to such Letter of Credit any restriction, reserve or capital requirement (for which such Issuing Lender is not otherwise compensated hereunder) not in effect on the date hereof or shall impose upon such Issuing Lender any unreimbursable loss, cost or expense which was not applicable on the date hereof and which such Issuing Lender in good faith deems material, or (vii) if such increase or extension is of an Existing Letter of Credit issued by JPMorgan Chase Bank, N.A. or The Bank of Nova Scotia unless the Borrower has specifically designated such Lender as one of the four Issuing Lender in writing to the Administrative Agent. If the terms of any letter of credit application referred to in the foregoing clause (iv) conflicts with the terms of this Agreement, the terms of this Agreement shall control.

          (c) Participations. With respect to each Letter of Credit described on Schedule 1.1(c) which is outstanding on the Closing Date, each Lender is deemed to have purchased a participation in the

35

related Letter of Credit Exposure equal to such Lender’s Pro Rata Share of such Letter of Credit Exposure on the Closing Date. On the date of the issuance or increase of any Letter of Credit on or after the Closing Date, each Issuing Lender shall be deemed to have sold to each other Lender and each other Lender shall have been deemed to have purchased from such Issuing Lender a participation in the Letter of Credit Exposure related to the Letters of Credit issued by such Issuing Lender equal to such Lender’s Pro Rata Share at such date and such sale and purchase shall otherwise be in accordance with the terms of this Agreement. Each Issuing Lender shall promptly deliver to the Administrative Agent by telex, telephone, or telecopy (or by e-mail with a return receipt requested) which the Administrative Agent will promptly deliver to each such participant Lender, a notice of each Letter of Credit of such Issuing Lender issued, increased or decreased, and the Administrative Agent shall also notify each Lender of the actual amount of such Lender’s participation in such Letter of Credit. Each Lender’s obligation to purchase participating interests pursuant to this Section, to make a Mandatory Revolving Borrowing as set forth in clause (d) below, to reimburse such Issuing Lender for such Lender’s Pro Rata Share of any payment under a Letter of Credit by such Issuing Lender not reimbursed in full by the Borrower, and to fund its participation interests in Letters of Credit as set forth below, shall be absolute and unconditional and shall not be affected by any circumstance, including (i) any of the circumstances described in paragraph (f) or (e) below, (ii) the occurrence and continuance of a Default, (iii) an adverse change in the financial condition of the Borrower, (iv) any deposit of cash or other securities as collateral or the provision of any other support for the Borrower’s reimbursement obligations related thereto, (v) any termination of this Agreement other than a termination in writing agreed to by each Issuing Lender which expressly provides for a termination of the Lenders’ reimbursement obligations owing to the Issuing Lenders hereunder, and (vi) any other circumstance, happening or event whatsoever, whether or not similar to any of the foregoing; provided that, a Lender may have a claim against an Issuing Lender for any such circumstance, happening or event constituting or arising from gross negligence or willful misconduct on the part of the such Issuing Lender.

          (d) Reimbursement. Upon receipt from the beneficiary of any Letter of Credit of any notice of a drawing under such Letter of Credit, the applicable Issuing Lender shall notify the Borrower and the Administrative Agent thereof (which the Administrative Agent will promptly forward to the Lenders). No later than 11:00 a.m. on the date of any payment to be made by such Issuing Lender under a Letter of Credit, the Borrower agrees to pay to such Issuing Lender an amount equal to any amount paid or to be paid by such Issuing Lender on such date under or in respect of such Letter of Credit and in the currency paid or to be paid by such Issuing Lender. Notwithstanding the foregoing, if, after the issuance of any Letter of Credit denominated in a Foreign Currency, such currency ceases to be an Agreed Currency as provided in the definition of Agreed Currency, then all payments to be made by the Borrower hereunder in such currency shall instead be made when due (either directly by the Borrower or through a deemed borrowing under clause (i) below) in Dollars in an amount equal to the Dollar Amount (as of the date of repayment) of such payment due, it being the intention of the parties hereto that the Borrower take all risks of the imposition of any such currency control or exchange regulations. In the event an Issuing Lender makes a payment pursuant to a request for draw presented under a Letter of Credit and such payment is not promptly reimbursed by the Borrower as required herein, such Issuing Lender shall give notice of such payment to the Administrative Agent (which the Administrative Agent will promptly forward to the Lenders). In such event, the Borrower shall be deemed to have requested a Mandatory Revolving Borrowing consisting of (i) for unreimbursed drawings under Letters of Credit denominated in Dollars or in a Foreign Currency which ceased to be an Agreed Currency, Prime Rate Advances, and (ii) for unreimbursed drawings under Letters of Credit denominated in Foreign Currencies, Eurocurrency Rate Advances in such Agreed Currency and in the amount of such unreimbursed amount with an Interest Period of one month; provided that, if the Revolving Commitments have terminated or otherwise expired, such Eurocurrency Rate Advances shall bear interest at the overnight Eurocurrency Rate. The applicable Issuing Lender shall give the Administrative Agent notice of such deemed Borrowing (A) by 12:00 p.m.

36

(Houston, Texas time) on the date before the proposed Borrowing is to be made in the case of a Prime Rate Advance or Eurocurrency Rate Advances bearing interest at the overnight Eurocurrency Rate and (B) by 12:00 p.m. (Houston, Texas time) on the fourth Business Day before the date of such proposed Borrowing in the case of a Eurocurrency Rate Advance denominated in a Foreign Currency with an Interest Period of one month (which notice the Administrative Agent shall promptly give to each Lender). Each Lender shall, no later than 1:00 p.m. on the Business Day specified in such notice, promptly make such funds available to the applicable Issuing Lender, in the applicable currency and in an amount equal to such Lender’s Pro Rata Share of the unreimbursed amount. The Borrower hereby unconditionally and irrevocably authorizes, empowers, and directs the Administrative Agent and the Lenders to record and otherwise treat each payment under a Letter of Credit not immediately reimbursed by the Borrower as a Borrowing comprised of Prime Rate Advances or Eurocurrency Rate Advances, as applicable, to the Borrower. If for any reason such Mandatory Revolving Borrowing cannot be made by any Lender, the request for such Mandatory Revolving Borrowing submitted by the applicable Issuing Lender as set forth herein shall be deemed to be a request by such Issuing Lender that each of the Lenders fund its risk participation in the relevant Letter of Credit and each Lender’s payment to the Administrative Agent for the account of the applicable Issuing Lender pursuant to this clause (d) shall be deemed payment in respect of such participation. If the funds are not made available by a Lender to the applicable Issuing Lender on the required date (either as the making of a Revolving Advance or the funding of its participation interest in such Letters of Credit), such Lender shall pay interest thereon to the applicable Issuing Lender at a rate per annum equal to the applicable Overnight Rate. At any time after any Lender has funded its participation in a Letter of Credit, if the applicable Issuing Lender receives any payment on the applicable Reimbursement Obligation from the Borrower, such Issuing Lender will distribute to such Lender its Pro Rata Share of such payment (appropriately adjusted, in the case of interest payments, to reflect the period of time during which such Lender’s participation was funded) in the same funds as those received by such Issuing Lender. All overdue Reimbursement Obligations of the Borrower shall bear interest as set forth in Section 2.6(e).

          (e) Obligations Unconditional. The obligations of the Borrower under this Agreement in respect of each Letter of Credit shall be unconditional and irrevocable, and shall be paid strictly in accordance with the terms of this Agreement under all circumstances, notwithstanding the following circumstances:

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

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

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

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

37

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

     (vi) any other circumstance or happening whatsoever, whether or not similar to any of the foregoing;

provided, however, that nothing contained in this paragraph (e) shall be deemed to constitute a waiver of any remedies of the Borrower in connection with the Letters of Credit.

          (f) Liability of Issuing Lenders. The Borrower assumes all risks of the acts or omissions of any beneficiary or transferee of any Letter of Credit with respect to its use of such Letter of Credit. No Issuing Lender nor any of its officers or directors shall be liable or responsible for, and the Borrower’s obligations hereunder shall not be affected by:

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

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

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

     (iv) any adverse change in the relevant exchange rates or in the availability of the relevant Agreed Currency to the Borrower or in the relevant currency markets generally; or

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

except that the Borrower shall have a claim against such Issuing Lender, and such Issuing Lender shall be liable to, and shall promptly pay to, the Borrower, to the extent of any direct, as opposed to consequential, damages suffered by the Borrower which the Borrower proves were caused by such Issuing Lender’s willful misconduct or gross negligence. In furtherance and not in limitation of the foregoing clause (f), the Issuing Lenders may accept documents that appear on their face to be in order, without responsibility for further investigation, regardless of any notice or information to the contrary and may refuse to accept documents that are not in strict conformity with the terms of the Letter of Credit, and any such acceptance or refusal shall not be deemed to constitute gross negligence or willful misconduct.

          (g) Cash Collateral Account. The Borrower shall, (i) within 10 days prior to the Maturity Date and (ii) at any time, if an Event of Default has occurred and is continuing, on the Business Day the Borrower receives written notice from an Issuing Lender or the Administrative Agent that collateralization is being required pursuant to Section 7.2(b) or Section 7.3(b), either (A) deposit cash in the Cash Collateral Account held by the Administrative Agent in an amount equal to the Letter of Credit Exposure as of such date or (B) cause to be issued an irrevocable standby letter of credit in favor of the applicable Issuing Lender and issued by a bank or other financial institution acceptable to such Issuing Lender and the Administrative Agent to support the full amount of the Letter of Credit Exposure as of such date. With respect to Letters of Credit issued in Foreign Currencies, if the Borrower elects to deposit

38

cash into the Cash Collateral Account pursuant to clause (A) above, then at the election of the Administrative Agent, the Borrower shall be required to either (1) deposit cash with the Administrative Agent in the Designated Currencies for the Letters of Credit or (2) deposit cash with the Administrative Agent in Dollars equal to the Dollar Amount of the Letter of Credit Exposure and, thereafter, deposit additional cash in Dollars at any time and from time to time as may be reasonably requested by the Administrative Agent in order to protect against the results of exchange rate fluctuations.

          (h) Letters of Credit Issued for Subsidiaries. Notwithstanding that a Letter of Credit issued or outstanding hereunder is in support of any obligations of, or is for the account of, a Subsidiary of the Borrower, the Borrower shall be obligated to reimburse the applicable Issuing Lender hereunder for any and all drawings under such Letter of Credit. The Borrower hereby acknowledges that the issuance of Letters of Credit for the account of Subsidiaries inures to the benefit of the Borrower, and that the Borrower’s business derives substantial benefits from the businesses of such Subsidiaries.

          (i) Information to Administrative Agent from Issuing Lenders. For purposes of calculating outstandings and Letters of Credit issued under this Agreement (i) on each March 31, June 30, September 30 and December 31, commencing June 30, 2008, and (ii) from time to time as the Administrative Agent may request, each Issuing Lender shall provide the Administrative Agent with a daily log, in form and detail reasonably acceptable to the Administrative Agent, setting forth the Dollar Amount of all outstanding Letters of Credit issued by such Issuing Lender using the Exchange Rate as most recently determined by the Administrative Agent.

     Section 2.14 Sharing of Payments, Etc. If any Lender shall obtain any payment (whether voluntary, involuntary, through the exercise of any right of set-off or otherwise) on account of its Advances or its share of Letter of Credit Obligations in excess of its Pro Rata Share of payments on account of the Advances or Letter of Credit Obligations obtained by all the Lenders, then such Lender shall notify the Administrative Agent and the other Lenders and forthwith purchase from the other Lenders, such participations in the Advances made by them or Letter of Credit Obligations held by them as shall be necessary to cause such purchasing Lender to share the excess payment ratably in accordance with the requirements of this Agreement with each of them; provided, however, that if all or any portion of such excess payment is thereafter recovered from such purchasing Lender, such purchase from each Lender shall be rescinded and such Lender shall repay to the purchasing Lender the purchase price to the extent of such Lender’s ratable share (according to the proportion of (a) the amount of the participation sold by such Lender to the purchasing Lender as a result of such excess payment to (b) the total amount of such excess payment) of such recovery, together with an amount equal to such Lender’s ratable share (according to the proportion of (i) the amount of such Lender’s required repayment to the purchasing Lender to (ii) the total amount of all such required repayments to the purchasing Lender) of any interest or other amount paid or payable by the purchasing Lender in respect of the total amount so recovered. The Borrower agrees that any Lender so purchasing a participation from another Lender pursuant to this Section 2.14 may, to the fullest extent permitted by law, unless and until rescinded as provided above, exercise all its rights of payment (including the right of set-off) with respect to such participation as fully as if such Lender were the direct creditor of the Borrower in the amount of such participation.

     Section 2.15 Increase of Commitment.

          (a) At any time prior to the Maturity Date, the Borrower may effectuate no more than two increases in the aggregate Revolving Commitments by an aggregate amount not greater than $1,000,000,000 (any such increase, a “Commitment Increase”), by designating either one or more of the existing Lenders (each of which, in its sole discretion, may determine whether and to what degree to participate in such Commitment Increase) or one or more other banks or other financial institutions (reasonably acceptable to the Administrative Agent, the Issuing Lenders and the Swingline Lenders) that

39

at the time agree, in the case of any such bank or financial institution that is an existing Lender to increase its Revolving Commitment as such Lender shall so select (an “Increasing Lender”) and, in the case of any other such bank or financial institution (an “Additional Lender”), to become a party to this Agreement; provided, however, that (i) the aggregate Revolving Commitments shall not at any time exceed $3,000,000,000 and (ii) the minimum amount of each such Commitment Increase shall not be less than $100,000,000. 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. The Borrower shall provide prompt notice of any proposed Commitment Increase pursuant to this Section 2.15 to the Administrative Agent and the Lenders.

          (b) Any Commitment Increase shall become effective upon (i) the receipt by the Administrative Agent of (A) an agreement in form and substance satisfactory to the Administrative Agent signed by the Borrower, each Increasing Lender and each Additional Lender, setting forth the new Revolving Commitment of each such Lender and setting forth the agreement of each Additional Lender to become a party to this Agreement and to be bound by all the terms and provisions hereof binding upon each Lender, and (B) such evidence of appropriate authorization on the part of the Borrower with respect to the Commitment Increase and such opinions of counsel for the Borrower with respect to the Commitment Increase as the Administrative Agent may reasonably request, and (ii) receipt by the Administrative Agent of a certificate (the statements contained in which shall be true) of a Responsible Officer of the 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 the Borrower in this Agreement are true and correct in all material respects, unless such representation or warranty relates to an earlier date.

          (c) The Borrower shall prepay any Advances outstanding on the effective date of such Commitment Increase to the extent necessary to keep the outstanding Revolving Advances ratable with any revised Pro Rata Share arising from any nonratable increases in the Revolving Commitments under this Section 2.15.

          (d) Notwithstanding any provision contained herein to the contrary, from and after the date of any Commitment Increase, all calculations and payments of interest on the Advances shall take into account the actual Revolving Commitment of each Lender and the principal amount outstanding of each Advance made by such Lender during the relevant period of time.

     Section 2.16 Lender Replacement.

          (a) Right to Replace. The Borrower shall have the right to replace each Lender affected by a condition under Sections 2.2(c)(v), 2.2(c)(viii), 2.9, 2.11 or 2.12 for more than 30 days, each Lender that is a Non-Consenting Lender under Section 2.19 and each Lender that is due interest based on the Mandatory Cost Rate (each such affected Lender, an “Affected Lender”) in accordance with the procedures in this Section 2.16 and provided that no reduction of the total Revolving Commitments occurs as a result thereof.

          (b) First Right of Refusal; Replacement.

     (i) Upon the occurrence of any condition permitting the replacement of a Lender, each Lender which is not an Affected Lender shall have the right, but not the obligation, to elect to increase its respective Revolving Commitment by an amount not to exceed the amount of the Revolving Commitments of the Affected Lenders, which election shall be made by written notice from each such Lender to the Administrative Agent and the Borrower given within 30 days after the date such condition occurs specifying the amount of such proposed increase in such Lender’s Revolving Commitment.

40

     (ii) If the aggregate amount of the proposed increases in Revolving Commitments of all such Lenders making such an election is in excess of the Revolving Commitments of the Affected Lenders, (A) the Revolving Commitments of the Affected Lenders shall be allocated pro rata among such Lenders based on the respective amounts of the proposed increases to Revolving Commitments elected by each of such Lenders, and (B) the respective commitments of such Lenders shall be increased by the respective amounts as so allocated so that after giving effect to such termination and increases the aggregate amount of the Revolving Commitments of the Lenders will be the same as prior to such termination.

     (iii) If the aggregate amount of the proposed increases to Revolving Commitments of all Lenders making such an election is less than the Revolving Commitments of the Affected Lenders, (A) the respective Revolving Commitments of such Lenders shall be increased by the respective amounts of their proposed increases, and (B) the Borrower shall add additional Lenders which are Eligible Assignees to this Agreement to replace such Affected Lenders, which additional Lenders would have aggregate Revolving Commitments no greater than those of the Affected Lenders minus the amounts thereof assumed by the other Lenders pursuant to such increases.

          (c) Procedure. Any assumptions of Revolving Commitments pursuant to this Section 2.16 shall be made by the purchasing Lender or Eligible Assignee and the selling Lender by entering into an Assignment and Assumption and by following the procedures in Section 9.6 for adding a Lender. In connection with the increase of the Revolving Commitments of any Lender or the introduction of any Eligible Assignee pursuant to the foregoing paragraph (b), each Lender with an increased Revolving Commitment and each new Eligible Assignee shall purchase from the Affected Lenders at par such Lender’s or such new Lender’s ratable share of the outstanding Advances and funded participations of the Affected Lenders and shall be automatically deemed to have assumed such Lender’s or such new Lender’s ratable share of the Affected Lenders’ participations in Letter of Credit Exposure.

     Section 2.17 Currency Fluctuations, Mandatory Prepayments and Deposits in the Cash Collateral Accounts.

          (a) Not later than 1:00 p.m., Houston, Texas time, on each Computation Date, the Administrative Agent shall determine the Exchange Rate as of such Computation Date and give notice thereof to the Borrower, each Lender, Swingline Lender and Issuing Lender. The Exchange Rate so determined shall become effective on the first Business Day after such Computation Date and shall remain effective through the next succeeding Computation Date.

          (b) If, on any Computation Date, the Dollar Amount of the sum of the outstanding principal amount of Revolving Advances plus the outstanding principal amount of Swingline Advances plus the Letter of Credit Exposure exceeds an amount equal to 102% of the aggregate Revolving Commitments then in effect, then the Administrative Agent shall give notice thereof to the Borrower and the Lenders, and the Borrower shall within five (5) Business Days thereafter prepay Advances, or if the Advances have been repaid or prepaid in full, make deposits into the Cash Collateral Account, such that after giving effect to such prepayment of Advances or deposits into the Cash Collateral Account, the Dollar Amount of the sum of the outstanding principal amount of Revolving Advances plus the outstanding principal amount of Swingline Advances plus the Letter of Credit Exposure does not exceed the aggregate Revolving Commitments then in effect.

41

          (c) If any currency shall cease to be an Agreed Currency as provided in the last sentence of the definition of “Agreed Currency”, then promptly, but in any event within five (5) Business Days of receipt of the notice from the Administrative Agent provided for in such sentence, the Borrower shall repay all Advances funded and denominated in such affected currency or Convert such Advances into Advances in Dollars or another Agreed Currency, subject to the other terms set forth in Article II.

          (d) Each prepayment pursuant to this Section 2.17 shall be accompanied by accrued interest on the amount prepaid to the date of such prepayment and amounts, if any, required to be paid pursuant to Section 2.8 as a result of such prepayment being made on such date.

          (e) Each payment of any Advance pursuant to this Section 2.17 or any other provision of this Agreement shall be made in a manner such that all Advances comprising part of the same Borrowing are paid in whole or ratably in part and each payment of an Advance shall be made in the Designated Currency in which such Advance was funded.

     Section 2.18 Market Disruption. Notwithstanding the satisfaction of all conditions referred to herein with respect to any proposed Borrowing consisting of Eurocurrency Advances denominated in any Foreign Currencies, if there shall occur on or prior to the date of such Borrowing any change in national or international financial, political or economic conditions or currency exchange rates or exchange controls which would in the reasonable opinion of the Administrative Agent or the Majority Lenders, make it impracticable for such Borrowing to be denominated in the Agreed Currency designated by the Borrower, then the Administrative Agent shall forthwith give notice thereof to the Borrower and the Lenders, and such Advances shall not thereafter be denominated and funded in such Agreed Currency but shall, except as otherwise set forth in Article II, be made on such date in Dollars, in an aggregate principal amount equal to the Dollar Amount of the aggregate principal amount specified in the related Notice of Borrowing, as the case may be, as Prime Rate Advances to the Borrower, unless the Borrower notifies the Administrative Agent at least one Business Day before such date that it elects not to borrow on such date.

     Section 2.19 Extension of Maturity Date.

          (a) Not earlier than 90 days prior to, nor later than 30 days prior to, each anniversary of the Closing Date, the Borrower may, upon notice to the Administrative Agent (which shall promptly notify the Lenders), request a one year extension of the Maturity Date then in effect (the “Present Maturity Date”). This option may be exercised only twice. Within 30 days of delivery of such notice, each Lender shall notify the 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 Agent shall promptly notify the Borrower and the Lenders of the Lenders’ responses.

          (b) The Maturity Date shall be extended only if the consenting Lenders (the “Consenting Lenders”) constitute Majority Lenders and only if the Revolving Commitments of the Consenting Lenders are at least equal to the Outstandings, after giving effect to the prepayment of Advances to Non-Consenting Lenders. 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 Agent and the Borrower shall promptly confirm to the Lenders such extension and the Extension Maturity Date. As a condition precedent to such extension, the Borrower shall pay or prepay all Advances, interest thereon and all other amounts due each Non-Consenting Lender on or before the Present Maturity Date, and shall deliver to the Administrative Agent a certificate of the Borrower (in

42

sufficient copies for each Lender) signed by a Responsible Officer of the Borrower (i) certifying and attaching the resolutions adopted by the Borrower approving or consenting to such extension and (ii) certifying that, before and after giving effect to such extension, (A) the representations and warranties contained in Article IV and the other Credit Documents are true and correct in all material respects, except to the extent that such representations and warranties expressly relate solely to an earlier date, in which case they shall have been true and correct in all material respects as of such earlier date, and except that for purposes of this Section 2.19, the representations and warranties contained in Section 4.6 shall be deemed to refer to the most recent statements furnished pursuant to subsection (b) of Section 5.6, and (B) no Default exists. If the Maturity Date has been extended, each Consenting Lender shall automatically be deemed to have purchased participations in each Letter of Credit, the related Letter of Credit Exposure, and each Swingline Advance equal to such Consenting Lender’s Pro Rata Share thereof after giving effect to the departure of the Non-Consenting Lenders and the elimination of their Revolving Commitments.

          (c) This Section shall supersede any provisions in Section 2.14 or 9.1 to the contrary.

          (d) The Borrower shall prepay any Advances outstanding on the Present Maturity Date (and pay any additional amounts required pursuant to Section 2.8) or borrow additional amounts to the extent necessary to keep outstanding Revolving Advances ratable with any revised and new Revolving Commitment of all Consenting Lenders effective as of the Present Maturity Date.

     Section 8.3 The Administrative Agent and its Affiliates. With respect to its Revolving Commitments, the Advances made by it and the Letters of Credit issued by it, the Administrative Agent shall have the same rights and powers under this Agreement as any other Lender and may exercise the same as though it were not an agent hereunder. The term “Lender” or “Lenders” shall, unless otherwise expressly indicated, include the Administrative Agent in its individual capacity. Administrative Agent and its respective Affiliates may accept deposits from, lend money to, act as trustee under indentures of, and generally engage in any kind of business with, the Borrower or any of its Subsidiaries, and any Person who may do business with or own securities of the Borrower or any such Subsidiary, all as if the Administrative Agent were not an agent hereunder and without any duty to account therefor to the Lenders.

     Section 8.4 Lender Credit Decision. Each Lender acknowledges that it has, independently and without reliance upon the Administrative Agent, the Arrangers or any other Lender and based on the financial statements referred to in Section 4.6 and such other documents and information as it has deemed appropriate, made its own credit analysis and decision to enter into this Agreement. Each Lender also acknowledges that it will, independently and without reliance upon the Administrative Agent, the Arrangers or any other Lender and based on such documents and information as it shall deem appropriate at the time, continue to make its own credit decisions in taking or not taking action under this Agreement.

     Section 8.5 Indemnification. The Lenders severally agree to indemnify the Administrative Agent, each Arranger and each Issuing Lender (to the extent not reimbursed by the Borrower), according to their respective Pro Rata Shares from and against any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind or nature whatsoever (including legal fees) which may be imposed on, incurred by, or asserted against the Administrative Agent, such Arranger or such Issuing Lender in any way relating to or arising out of this Agreement or any other Credit Document or any action taken or omitted by the Administrative Agent, such Arranger or such Issuing Lender under this Agreement or any other Credit Document (INCLUDING THE ADMINISTRATIVE AGENT’S, THE ARRANGER’S OR SUCH ISSUING LENDER’S OWN NEGLIGENCE), provided that no Lender shall be liable for any portion of such liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements found by a final

59

judgment by a court of competent jurisdiction to have resulted from the Administrative Agent’s, such Arranger’s or such Issuing Lender’s gross negligence or willful misconduct. Without limitation of the foregoing, each Lender agrees to (a) reimburse the Administrative Agent promptly upon demand for its ratable share of any out-of-pocket expenses (including counsel fees) incurred by the Administrative Agent in connection with the preparation, execution, delivery, modification or amendment of this Agreement or any other Credit Document, to the extent that the Administrative Agent is not reimbursed for such expenses by the Borrower and (b) reimburse the Administrative Agent promptly upon demand for its ratable share of any out-of-pocket expenses (including counsel fees) incurred by the Administrative Agent in connection with the administration or enforcement (whether through negotiations, legal proceedings or otherwise) of, or legal advice in respect of rights or responsibilities under, this Agreement or any other Credit Document, to the extent that the Administrative Agent is not reimbursed for such expenses by the Borrower.

Any Issuing Lender designated in writing by the Borrower as provided in the definition of “Issuing Lender” may be removed at any time with or without cause by the Borrower. Upon receipt of notice of any such resignation or removal (other than a removal of an Issuing Lender by the Borrower), the applicable Majority Lenders shall have the right to appoint a successor Administrative Agent or Issuing Lender with, if an Event of Default has not occurred and is not continuing, the consent of the Borrower, which consent shall not be unreasonably withheld or delayed. If no successor Administrative Agent or Issuing Lender shall have been so appointed by the Majority Lenders, and shall have accepted such appointment, within 30 days after the retiring or removed Administrative Agent’s or Issuing Lender’s giving of notice of resignation or the Majority Lenders’ removal of the retiring Administrative Agent or Issuing Lender, then the retiring or removed Administrative Agent or Issuing Lender may, on behalf of the Lenders and the Borrower, appoint a successor Administrative Agent or Issuing Lender, which shall be a commercial bank meeting the financial requirements of an Eligible Assignee and, in the case of a Issuing Lender, a Lender. Upon the acceptance of any appointment as Administrative Agent or Issuing Lender by a successor Administrative Agent or Issuing Lender, such successor Administrative Agent or Issuing Lender shall thereupon succeed to and become vested with all the rights, powers, privileges and duties of the retiring or removed Administrative Agent or Issuing Lender, and the retiring or removed Administrative Agent or Issuing Lender shall be discharged from its duties and obligations under this Agreement and the other Credit Documents, except that the retiring or removed Issuing Lender shall remain the Issuing Lender with respect to any Letters of Credit issued by such Issuing Lender and outstanding on the effective date of its resignation or removal and the provisions affecting such Issuing Lender with respect to such Letters of Credit shall inure to the benefit of the retiring or removed Issuing Lender until the termination of all such Letters of Credit and the payment of all outstanding Obligations owing to such Issuing Lender.

By executing and delivering an Assignment and Acceptance, the Lender thereunder and the assignee thereunder confirm to and agree with each other and the other parties hereto as follows: (i) other than as provided in such Assignment and Acceptance, such Lender makes no representation or warranty and assumes no responsibility with respect to any statements, warranties or representations made in or in connection with this Agreement or the execution, legality, validity, enforceability, genuineness, sufficiency or value of this Agreement or any other instrument or document furnished pursuant hereto; (ii) such Lender makes no representation or warranty and assumes no responsibility with respect to the financial condition of the Borrower or the performance or observance by the Borrower of any of its obligations under this Agreement or any other instrument or document furnished pursuant hereto; (iii) such assignee confirms that it has received a copy of this Agreement, together with copies of the financial statements referred to in Section 4.6 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) such assignee will, independently and without reliance upon the Administrative Agent, such Lender or any other Lender and based on such documents and information as it shall deem appropriate at the time, continue to make its own credit decisions in taking or not taking action under this Agreement; (v) such assignee appoints and authorizes the Administrative Agent to take such action as agent on its behalf and to exercise such powers under this Agreement as are delegated to the Administrative Agent by the terms hereof, together with such powers as are reasonably incidental thereto; and (vi) such assignee agrees that it will perform in accordance with their terms all of the obligations which by the terms of this Agreement are required to be performed by it as a Lender.

          (c) The Register. The Administrative Agent shall maintain at its respective address referred to in Section 9.2 a copy of each Assignment and Acceptance delivered to and accepted by it and a register for the recordation of the names and addresses of the respective Lenders and the Revolving Commitment and principal amount of the Advances owing to, each Lender from time to time (the “Register”). The entries in the Register shall be conclusive and binding for all purposes, absent manifest error, and the Borrower, the Administrative Agent, the Issuing Lenders, and the Lenders may treat each Person whose name is recorded in the Register as a Lender hereunder for all purposes of this Agreement. At any reasonable time and from time to time upon reasonable prior notice, the Register shall be available (i) for inspection by the Borrower, (ii) for inspection by each Lender as to its Revolving Commitment and principal amount of Advances owing to it, and (iii) for inspection by each Issuing Lender and each Swingline Lender for purposes of determining each Lender’s participation interest in Letters of Credit and Swingline Advances.

          (d) Procedures. Upon its receipt of an Assignment and Acceptance executed by a Lender and an Eligible Assignee, together with the Notes, if any, subject to such assignment, the Administrative Agent shall, if such Assignment and Acceptance has been completed and is in substantially the form of the attached Exhibit A, (i) accept such Assignment and Acceptance, (ii) record the information contained therein in the Register, and (iii) give prompt notice thereof to the Borrower.

          (e) Participations. Each Lender may sell participations to one or more banks or other entities in or to all or a portion of its rights and obligations under this Agreement (including all or a portion of its Revolving Commitment, the Advances owing to it, its participation interest in the Letter of Credit Obligations, and the Notes held by it, if any); provided, however, that (i) such Lender’s obligations under this Agreement (including its Revolving Commitment to the Borrower hereunder) shall remain unchanged, (ii) such Lender shall remain solely responsible to the other parties hereto for the performance of such obligations, (iii) such Lender shall remain the holder of any such Obligations for all purposes of this Agreement, (iv) the Borrower, the Administrative Agent, and the Issuing Lenders and the other Lenders shall continue to deal solely and directly with such Lender in connection with such Lender’s rights and obligations under this Agreement, (v) such Lender shall not require the participant’s consent to

64

any matter under this Agreement, except for change in the principal amount of any Obligation in which the participant has an interest, reductions in fees or interest, or extending the Maturity Date, and (vi) such Lender shall give prompt prior notice to the Borrower of each such participation to be sold by such Lender. The Borrower hereby agrees that participants shall have the same rights under Sections 2.8, 2.9, 2.11(c), 9.4 and 9.7 hereof as the Lender to the extent of their respective participations. Notwithstanding the foregoing and so long as no Event of Default has occurred and is continuing, upon the receipt of notice by the Borrower of the sale of a participation by any Lender to one or more banks or other entities (other than an Affiliate of such Lender) in or to all or a portion of its rights and obligations under this Agreement (each such bank or other entity, a “Proposed Participant”), the Borrower shall have the right, but not the obligation, to select additional lenders to replace such Proposed Participant on the same terms and conditions as the Proposed Participant upon prompt written notice from the Borrower to the Administrative Agent and the Lender selling such participation. The Borrower shall have ten days from the date of its receipt of notice of the proposed sale of such participation to the Proposed Participant to select replacement lenders to replace such Proposed Participant. If the Borrower does not select any replacement lenders or does not elect to select any replacement lenders the applicable Lender may sell such participation to the Proposed Participant.

     Section 9.7 Indemnification. The Borrower shall indemnify the Administrative Agent, each Arranger, each Lender (including any lender which was a Lender hereunder prior to any full assignment of its Revolving Commitment), each Issuing Lender, each Swingline Lender and each affiliate thereof and their respective directors, officers, employees and agents from, and discharge, release, and hold each of them harmless against, any and all losses, liabilities, claims or damages to which any of them may become subject, insofar as such losses, liabilities, claims or damages arise out of or result from (i) the execution or delivery of this Agreement or any agreement or instrument contemplated hereby, the performance by the parties hereto of their respective obligations hereunder or the consummation of the Merger or any other transactions contemplated hereby, (ii) any actual or proposed use by the Borrower or any Affiliate of the Borrower of the proceeds of any Advance or Letter of Credit, (iii) any breach by the Borrower of any provision of this Agreement or any other Credit Document, (iv) any Environmental Claim or requirement of Environmental Laws concerning or relating to the present or previously-owned or operated properties, or the operations or business, of the Borrower or any of its Subsidiaries, and (v) any investigation, litigation or other proceeding (including any threatened investigation or proceeding) relating to the foregoing, and the Borrower shall reimburse the Administrative Agent, each Arranger, the Issuing Lender, each Swingline Lender and each Lender, and each affiliate thereof and their respective directors, officers, employees and agents, upon demand for any reasonable out-of-pocket expenses (including legal fees) incurred in connection with any such losses, liabilities, claims, damages, investigation, litigation, Environmental Claim or requirement, or other proceeding; and EXPRESSLY INCLUDING ANY SUCH LOSSES, LIABILITIES, CLAIMS, DAMAGES, OR EXPENSE INCURRED BY REASON OF THE PERSON BEING INDEMNIFIED’S OWN NEGLIGENCE, BUT EXCLUDING ANY SUCH LOSSES, LIABILITIES, CLAIMS, DAMAGES OR EXPENSES FOUND BY A FINAL JUDGMENT BY A COURT OF COMPETENT JURISDICTION TO HAVE RESULTED FROM THE GROSS NEGLIGENCE OR WILLFUL MISCONDUCT OF THE PERSON TO BE INDEMNIFIED.

     Section 9.8 Execution in Counterparts. This Agreement may be executed in any number of counterparts and by different parties hereto in separate counterparts, each of which when so executed shall be deemed to be an original and all of which taken together shall constitute one and the same agreement.

     Section 9.9 Survival of Representations, etc. All representations and warranties contained in this Agreement or made in writing by or on behalf of the Borrower in connection herewith shall survive

65

the execution and delivery of this Agreement and the Credit Documents, the making of the Advances and any investigation made by or on behalf of the Lenders, none of which investigations shall diminish any Lender’s right to rely on such representations and warranties. All obligations of the Borrower provided for in Sections 2.8, 2.9, 2.11, 9.4, 9.7 and 9.16 shall survive any termination of this Agreement and repayment in full of the Obligations.

     Section 9.10 Severability. In case one or more provisions of this Agreement or the other Credit Documents shall be invalid, illegal or unenforceable in any respect under any applicable Legal Requirement, the validity, legality and enforceability of the remaining provisions contained herein or therein shall not be affected or impaired thereby.

     Section 9.11 Usury Not Intended. It is the intent of the Borrower and each Lender in the execution and performance of this Agreement and the other Credit Documents to contract in strict compliance with applicable usury laws, including conflicts of law concepts, governing the Advances of each Lender including such applicable Legal Requirements of the State of Texas and the United States of America from time to time in effect. In furtherance thereof, each Lender and the Borrower stipulate and agree that none of the terms and provisions contained in this Agreement or the other Credit Documents shall ever be construed to create a contract to pay, as consideration for the use, forbearance or detention of money, interest at a rate in excess of the Maximum Rate and that for purposes hereof “interest” shall include the aggregate of all charges which constitute interest under such laws that are contracted for, charged or received under this Agreement. In the event that the Obligations are accelerated by reason of any election of the holder thereof resulting from any Event of Default under this Agreement or otherwise, or in the event of any required or permitted prepayment, then such consideration that constitutes interest may never include more than the Maximum Rate and excess interest, if any, provided for in this Agreement or otherwise shall be canceled automatically as of the date of such acceleration or prepayment and, if theretofore paid, shall be credited on the applicable Obligations (or, if the applicable Obligations shall have been paid in full, refunded to the Borrower). The provisions of this Section shall control over all other provisions of this Agreement or the other Credit Documents which may be in apparent conflict herewith.

     Section 9.12 Confidentiality. None of the Administrative Agent, Issuing Lenders or Lenders shall disclose any Confidential Information to any Person without the consent of the Borrower, other than (a) to the Administrative Agent’s, Issuing Lender’s or Lender’s Affiliates and their officers, directors, employees, agents and advisors, (b) to actual or prospective Eligible Assignees and participants and their officers, directors, employees, agents and advisors, (c) to any direct, indirect, actual or prospective counterparty (and its advisor) to any swap, derivative or securitization transaction related to the obligations under this Agreement, and then, in any event, only on a confidential basis, (d) as required by any law, rule or regulation or judicial process, (e) as requested or required by any state, Federal or foreign authority or examiner (including the National Association of Insurance Commissioners or any similar organization or quasi-regulatory authority) regulating such Issuing Lender, such Lender or Administrative Agent, or to insurers, insurance brokers or direct or indirect providers of credit protection when required by it, provided that, prior to any such disclosure, such Person shall undertake to preserve the confidentiality of any Confidential Information relating to the Borrower received by it from such Issuing Lender, such Lender or Administrative Agent, (f) to any rating agency when required by it, provided that, prior to any such disclosure, such rating agency shall undertake to preserve the confidentiality of any Confidential Information relating to the Borrower received by it from such Issuing Lender, such Lender or Administrative Agent, (g) in connection with any litigation or proceeding to which Administrative Agent, such Issuing Lender or such Lender or any of its Affiliates may be a party or (h) in connection with the exercise of any right or remedy under this Agreement or any other Credit Document. NOTWITHSTANDING ANYTHING TO THE CONTRARY CONTAINED HEREIN, nothing in

66

this Agreement shall (a) restrict the Administrative Agent, any Issuing Lender or any Lender from providing information to any bank or other regulatory or governmental authorities, including the Federal Reserve Board and its supervisory staff; (b) require or permit the Administrative Agent, any Issuing Lender or any Lender to disclose to the Borrower that any information will be or was provided to the Federal Reserve Board or any of its supervisory staff; or (c) require or permit the Administrative Agent, any Issuing Lender or any Lender to inform the Borrower of a current or upcoming Federal Reserve Board examination or any nonpublic Federal Reserve Board supervisory initiative or action.

     Section 9.13 Governing Law; Submission to Jurisdiction.

     (a) This Agreement, the Notes and the other Credit Documents shall be governed by, and construed and enforced in accordance with, the laws of the State of New York without regard to conflict of law principles thereof.

     (b) Any legal action or proceeding with respect to this Agreement or any other Credit Document may be brought in the courts of the state of New York sitting in New York City or of the United States for the Southern District of such state, and by execution and delivery of this Agreement, the Borrower, the Administrative Agent, each Issuing Lender, each Swingline Lender and each Lender consents, for itself and in respect of its property, to the non-exclusive jurisdiction of those courts. The Borrower, the Administrative Agent, each Issuing Lender, each Swingline Lender and each Lender irrevocably waives any objection, including any objection to the laying of venue or based on the grounds of forum non conveniens, which it may now or hereafter have to the bringing of any action or proceeding in such jurisdiction in respect of this Agreement or any other Credit Document or other document related thereto.

     (c) The Borrower irrevocably consents to the service of any and all process in any such action or proceeding by the mailing of copies of such process to it at the address specified for it in this Agreement.

     (d) Nothing in this Section 9.13 shall affect the right of the Administrative Agent, any Issuing Lender, any Swingline Lender or any other Lender to serve legal process in any other manner permitted by law or affect the right of the Administrative Agent, any Issuing Lender, any Swingline Lender or any other Lender to bring any action or proceeding against the Borrower in the courts of any other jurisdiction.

     Section 9.14 Waiver of Jury Trial. The Borrower, the Issuing Lenders, the Swingline Lenders, the Lenders and the Administrative Agent hereby irrevocably waive any and all right to trial by jury in respect of any legal proceeding, directly or indirectly (whether sounding in tort, contract or otherwise), arising out of or relating to this Agreement, any other Credit Document, any of the transactions contemplated hereby, or the relationship established hereunder.

     Section 9.15 Waiver of Consequential Damages. To the extent permitted by applicable law, Borrower shall not assert, and the Borrower hereby waives, any claim against any other party hereto and each affiliate thereof and their respective directors, officers, employees and agents, on any theory of liability, for special, indirect, consequential or punitive damages (as opposed to direct or actual damages) arising out of, in connection with, or as a result of, this Agreement or any other Credit Document, the Merger, any Advance or Letter of Credit or the use of the proceeds thereof.

67

     Section 9.16 Judgment Currency. If for the purposes of obtaining judgment in any court it is necessary to convert a sum due from the Borrower hereunder in the currency expressed to be payable herein (the “specified currency”) into another currency, the parties hereto agree, to the fullest extent that they may effectively do so, that the rate of exchange used shall be that at which in accordance with usual and customary banking procedures the Administrative Agent could purchase the specified currency with such other currency at any of the Administrative Agent’s offices in the United States of America on the Business Day preceding that on which final, non-appealable judgment is given. The obligations of the Borrower in respect of any sum due to any Lender, any Issuing Lender or the Administrative Agent hereunder shall, notwithstanding any judgment in a currency other than the specified currency, be discharged only to the extent that on the Business Day following receipt by such Lender, such Issuing Lender or the Administrative Agent (as the case may be) of any sum adjudged to be so due in such other currency such Lender, such Issuing Lender or the Administrative Agent (as the case may be) may in accordance with normal, reasonable banking procedures purchase the specified currency with such other currency. If the amount of the specified currency so purchased is less than the sum originally due to such Lender, such Issuing Lender or the Administrative Agent, as the case may be, in the specified currency, the Borrower agrees, to the fullest extent that it may effectively do so, as a separate obligation and notwithstanding any such judgment, to indemnify such Lender, such Issuing Lender or the Administrative Agent, as the case may be, against such loss, and if the amount of the specified currency so purchased exceeds (a) the sum originally due to any Lender, such Issuing Lender or the Administrative Agent, as the case may be, in the specified currency and (b) any amounts shared with other Lenders as a result of allocations of such excess as a disproportionate payment to such Lender under Section 2.14, each Lender, Issuing Lender or the Administrative Agent, as the case may be, agrees to promptly remit such excess to the Borrower. All obligations of the Borrower provided in this Section 9.16 shall survive any termination of this Agreement and repayment in full of the Obligations.

     Section 9.17 Headings Descriptive. The headings of the several Sections and paragraphs of the Agreement are inserted for convenience only and shall not in any way affect the meaning or construction of any provision of this Agreement.

     Section 9.18 USA Patriot Act. Each Lender that is subject to the Act (as hereinafter defined) and the Administrative Agent (for itself and not on behalf of any Lender) hereby notifies the Borrower that pursuant to the requirements of the USA Patriot Act (Title III of Pub. L. 107-56 (signed into law October 26, 2001)) (the “Act”), it is required to obtain, verify and record information that identifies the Borrower, which information includes the name and address of the Borrower and other information that will allow such Lender or the Administrative Agent, as applicable, to identify the Borrower in accordance with the Act.

This written agreement and the Credit Documents, as defined in this Agreement, represent the final agreement among the parties and may not be contradicted by evidence of prior, contemporaneous, or subsequent oral agreements of the parties.

Schedule 1.1(a)

SCHEDULE 1.1(b)

MANDATORY COST RATE

1. The Mandatory Cost Rate (to the extent applicable) is an addition to the interest rate otherwise payable to compensate Lenders for the cost of compliance with:

(a)	the requirements of the Bank of England and/or the Financial Services Authority (or, in either case, any other authority which replaces all or any of its functions); or
(b)	the requirements of the European Central Bank.

2. On the first day of each Interest Period (or as soon as possible thereafter) the Administrative Agent shall calculate, as a percentage rate, a rate (the “Additional Cost Rate”) for each Lender, in accordance with the paragraphs set out below. The Mandatory Cost Rate will be calculated by the Administrative Agent as a weighted average of the Lenders’ Additional Cost Rates (weighted in proportion to the percentage participation of each Lender in the relevant Advance) and will be expressed as a percentage rate per annum. The Administrative Agent will, at the request of the Borrower or any Lender, deliver to the Borrower or such Lender as the case may be, a statement setting forth the calculation of any Mandatory Cost Rate.

3. The Additional Cost Rate for any Lender lending from a Lending Office in a Participating Member State will be the percentage notified by that Lender to the Administrative Agent. This percentage will be certified by such Lender in its notice to the Administrative Agent to be its reasonable determination of the cost (expressed as a percentage of such Lender’s participation in all Advances made from such Lending Office) of complying with the minimum reserve requirements of the European Central Bank in respect of Advances made from that Lending Office.

4. The Additional Cost Rate for any Lender lending from a Lending Office in the United Kingdom will be calculated by the Administrative Agent as follows:

(a) in relation to any Advance in Pounds Sterling:

AB+C(B-D)+E x 0.01	per cent per annum
100 — (A+C)

(b) in relation to any Advance in any currency other than Pounds Sterling:

E x 0.01	per cent per annum
300

Where:

“A”	is the percentage of Eligible Liabilities (assuming these to be in excess of any stated minimum) which that Lender is from time to time required to maintain as an interest free cash ratio deposit with the Bank of England to comply with cash ratio requirements.
“B”	is the percentage rate of interest (excluding the Applicable Margin, the Mandatory Cost Rate and any interest charged on overdue amounts pursuant to the first sentence of Section 2.6(b)) payable for the relevant Interest Period of such Advance.

Schedule 1.1(b)

“C”	is the percentage (if any) of Eligible Liabilities which that Lender is required from time to time to maintain as interest bearing Special Deposits with the Bank of England.
“D”	is the percentage rate per annum payable by the Bank of England on interest bearing Special Deposits.
“E”	is designed to compensate Lenders for amounts payable under the Fees Rules and is calculated by the Administrative Agent as being the average of the most recent rates of charge supplied by the Lenders to the Administrative Agent pursuant to paragraph 7 below and expressed in pounds per £1,000,000.

5. For the purposes of this Schedule:

(a)	“Eligible Liabilities” and “Special Deposits” have the meanings given to them from time to time under or pursuant to the Bank of England Act 1998 or (as may be appropriate) by the Bank of England;
(b)	“Fees Rules” means the rules on periodic fees contained in the FSA Supervision Manual or such other law or regulation as may be in force from time to time in respect of the payment of fees for the acceptance of deposits;
(c)	“Fee Tariffs” means the fee tariffs specified in the Fees Rules under the activity group A.1 Deposit acceptors (ignoring any minimum fee or zero rated fee required pursuant to the Fees Rules but taking into account any applicable discount rate); and
(d)	“Tariff Base” has the meaning given to it in, and will be calculated in accordance with, the Fees Rules.

6. In application of the above formulae, A, B, C and D will be included in the formulae as figures and not as percentages (i.e. 5% will be included in the formula as 5 and not as 0.05). A negative result obtained by subtracting D from B shall be taken as zero. The resulting figures shall be rounded to four decimal places.

7. If requested by the Administrative Agent or the Borrower, each Lender with a Lending Office in the United Kingdom or a Participating Member State shall, as soon as practicable after publication by the Financial Services Authority, supply to the Administrative Agent and the Borrower, the rate of charge payable by such Lender to the Financial Services Authority pursuant to the Fees Rules in respect of the relevant financial year of the Financial Services Authority (calculated for this purpose by such Lender as being the average of the Fee Tariffs applicable to such Lender for that financial year) and expressed in pounds per £1,000,000 of the Tariff Base of such Lender.

8. Each Lender shall supply any information required by the Administrative Agent for the purpose of calculating its Additional Cost Rate. In particular, but without limitation, each Lender shall supply the following information in writing on or prior to the date on which it becomes a Lender:

(a) the jurisdiction of the Lending Office out of which it is making available its participation in the relevant Advance; and

Schedule 1.1(b)

(b) any other information that the Administrative Agent may reasonably require for such purpose.

Each Lender shall promptly notify the Administrative Agent in writing of any change to the information provided by it pursuant to this paragraph.

9. The percentages of each Lender for the purpose of A and C above and the rates of charge of each Lender for the purpose of E above shall be determined by the Administrative Agent based upon the information supplied to it pursuant to paragraphs 7 and 8 above and on the assumption that, unless a Lender notifies the Administrative Agent to the contrary, each Lender’s obligations in relation to cash ratio deposits and Special Deposits are the same as those of a typical bank from its jurisdiction of incorporation with a Lending Office in the same jurisdiction as its Lending Office.

10. The Administrative Agent shall have no liability to any Person if such determination results in an Additional Cost Rate which over- or under-compensates any Lender and shall be entitled to assume that the information provided by any Lender pursuant to paragraphs 3, 7 and 8 above is true and correct in all respects.

11. The Administrative Agent shall distribute the additional amounts received as a result of the Mandatory Cost Rate to the Lenders on the basis of the Additional Cost Rate for each Lender based on the information provided by each Lender pursuant to paragraphs 3, 7 and 8 above.

12. Any determination by the Administrative Agent pursuant to this Schedule in relation to a formula, the Mandatory Cost Rate, an Additional Cost Rate or any amount payable to a Lender shall, in the absence of manifest error, be conclusive and binding on all parties hereto.

13. The Administrative Agent may from time to time, after consultation with the Borrower and the Lenders, determine and notify to all parties any amendments which are required to be made to this Schedule in order to comply with any change in law, regulation or any requirements from time to time imposed by the Bank of England, the Financial Services Authority or the European Central Bank (or, in any case, any other authority which replaces all or any of their respective functions) and any such determination shall, in the absence of manifest error, be conclusive and binding on all parties hereto.

          (e) Administrative Agent Reliance. Unless the Administrative Agent shall have received notice from a Lender before the date of any Revolving Borrowing that such Lender will not make available to the Administrative Agent such Lender’s Pro Rata Share of such Borrowing, the Administrative Agent may assume that such Lender has made its Pro Rata Share of such Borrowing available to the Administrative Agent on the date of such Borrowing in accordance with paragraph (a) of this Section 2.2 and the Administrative Agent may, in reliance upon such assumption, make available to the Borrower on such date a corresponding amount. If and to the extent that such Lender shall not have so made its Pro Rata Share of such Borrowing available to the Administrative Agent, such Lender and the Borrower severally agree to immediately repay to the Administrative Agent on demand such corresponding amount, together with interest on such amount, for each day from the date such amount is made available to the Borrower until the date such amount is repaid to the Administrative Agent, at (i) in the case of the Borrower, the interest rate applicable on such day to Advances comprising such Borrowing and (ii) in the case of such Lender, the Overnight Rate for such day. If such Lender shall repay to the Administrative Agent such corresponding amount and interest as provided above, such corresponding amount so repaid shall constitute such Lender’s Advance as part of such Borrowing for purposes of this Agreement even though not made on the same day as the other Advances comprising such Borrowing.

          (f) Lender Obligations Several. The failure of any Lender to make the Advance to be made by it as part of any Borrowing shall not relieve any other Lender of its obligation, if any, to make its Advance on the date of such Borrowing. No Lender shall be responsible for the failure of any other Lender to make the Advance to be made by such other Lender on the date of any Borrowing.

          (g) Evidence of Obligations.

     (i) The Advances made by each Lender shall be evidenced by one or more accounts or records maintained by such Lender and by the Administrative Agent in the ordinary course of business. The accounts or records maintained by Administrative Agent and the Lenders shall be conclusive absent manifest error of the amount of the Advances made by such Lenders to the Borrower and the interest and payments thereon. Any failure to so record or any error in doing so shall not, however, limit or otherwise affect the obligation of the Borrower 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 Administrative Agent in respect of such matters, the accounts and records of the Administrative Agent shall control in the absence of manifest error. Upon the request of any Lender to the Borrower made through the Administrative Agent, the Borrower shall execute and deliver to such Lender (through the Administrative Agent) the applicable Note or Notes which shall evidence such Lender’s Advances to the Borrower in addition to such accounts or records. Each Lender may attach schedules to such Notes and endorse thereon the date, Type (if applicable), amount, currency and maturity of its Advances and payments with respect thereto.

     Section 2.3 Fees.

          (a) Facility Fees. The Borrower agrees to pay to the Administrative Agent for the account of each Lender, a daily facility fee (the “Facility Fee”) on the amount of such Lender’s Revolving Commitment at a per annum rate equal to the Applicable Margin for facility fees for the period from the Closing Date until the Maturity Date, such fees due and payable quarterly in arrears on the tenth (10^th) day after the end of each March, June, September and December, commencing June 30, 2008, and on the Maturity Date.

For purposes of calculating such Utilization Fee, outstandings for Eurocurrency Rate Advances denominated in Foreign Currencies shall be converted to their Dollar Amounts on each date that such Utilization Fee is due hereunder using the then effective Exchange Rate.

          (c) Administrative Agent Fees. The Borrower agrees to pay when due to the Administrative Agent for its benefit the fees set forth in the Agent’s Fee Letter.

     Section 2.4 Reduction of Commitments. The Borrower shall have the right, upon at least three Business Days’ irrevocable notice to the Administrative Agent and the Lenders, to terminate in whole or reduce ratably in part the unused portion of the Revolving Commitments; provided that, each partial reduction shall be in the aggregate amount of $3,000,000 or an integral multiple of $1,000,000 in excess thereof. Any reduction or termination of the Revolving Commitments pursuant to this Section 2.4 shall be permanent, with no obligation of the Lenders to reinstate such Revolving Commitments and the commitment fees provided for in Section 2.3(a) shall thereafter be computed on the basis of the Revolving Commitments, as so reduced.

     Section 2.5 Repayment of Advances. The Borrower shall repay the outstanding principal amount of each Revolving Advance on the Maturity Date and in the Designated Currency in which each such Advance was funded.

          (d) Usury Recapture. As to each Lender, in the event the rate of interest chargeable under this Agreement or the Notes at any time is greater than the Maximum Rate, the unpaid principal amount of Obligations owing to such Lender shall bear interest at the Maximum Rate until the total amount of interest paid or accrued on such Obligations equals the amount of interest which would have been paid or accrued on such Obligations if the stated rates of interest set forth in this Agreement had at all times been in effect. In the event, upon payment in full of such Obligations, the total amount of interest paid or accrued under the terms of this Agreement and the Notes as to any Lender is less than the total amount of interest which would have been paid or accrued if the rates of interest set forth in this Agreement had, at all times, been in effect, then the Borrower shall, to the extent permitted by applicable Legal Requirements, pay the Administrative Agent for the account of such Lenders an amount equal to the difference between (i) the lesser of (A) the amount of interest which would have been charged on Obligations owing to such Lender if the Maximum Rate had, at all times, been in effect and (B) the amount of interest which would have accrued on such Obligations if the rates of interest set forth in this Agreement had at all times been in effect and (ii) the amount of interest actually paid or accrued under this Agreement on such Obligations. In the event any Lender ever receives, collects or applies as interest any sum in excess of the Maximum Rate, such excess amount shall, to the extent permitted by law, be applied to the reduction of the principal balance of the Obligations owing to it, and if no such principal is then outstanding, such excess or part thereof remaining shall be paid to the Borrower.

          (e) Other Amounts Overdue. If any amount payable under this Agreement other than the Advances is not paid when due and payable, including accrued interest and fees, then such overdue amount shall accrue interest hereon due and payable on demand at a rate per annum equal to the lesser of (i) Adjusted Prime Rate plus two percent (2%) and (ii) the Maximum Rate, from the date such amount became due until the date such amount is paid in full.

     Section 2.7 Prepayments.

          (a) Right to Prepay. The Borrower shall have no right to prepay any principal amount of any Advance except as provided in this Section 2.7.

          (b) Optional Prepayments. The Borrower may elect to prepay any of the Advances, after giving notice thereof to the Administrative Agent and the Lenders by 12:00 p.m. (Houston, Texas) for Advances denominated in Dollars and by 12:00 p.m. in the Applicable Time for Advances denominated in Foreign Currencies and (i) at least three Business Days’ prior to the day of prepayment of any Eurocurrency Rate Advances and (ii) the day prior to the prepayment of any Prime Rate Advance. Such notice shall be by telephone or telecopier, and if by telephone, confirmed promptly in writing, and must state the proposed date and aggregate principal amount of such prepayment, whether such prepayment should be applied to reduce outstanding Revolving Advances, and if applicable, the relevant Interest Period for the Advances to be prepaid. If any such notice is given, the Borrower shall prepay Advances comprising part of the same Borrowing in whole or ratably in part in an aggregate principal

21

amount equal to the amount specified in such notice, and shall also pay accrued interest to the date of such prepayment on the principal amount prepaid and amounts, if any, required to be paid pursuant to Section 2.8 as a result of such prepayment being made on such date; provided, however, that (i) each partial prepayment of Eurocurrency Rate Advances shall be in an aggregate principal amount of not less than $3,000,000 and in integral multiples of $1,000,000 in excess thereof, (ii) each partial prepayment of Prime Rate Advances shall be in an aggregate principal amount of not less than $500,000 and in integral multiples of $100,000 in excess thereof, and (iii) any prepayment of an Advance shall be made in the Designated Currency in which such Advance was funded. Each prepayment pursuant to this Section 2.7(b) shall be accompanied by accrued interest on the amount prepaid to the date of such prepayment and amounts, if any, required to be paid pursuant to Section 2.8 as a result of such prepayment being made on such date.

          (c) Ratable Payments. Each payment of any Advance pursuant to this Section 2.7 or any other provision of this Agreement shall be made in a manner such that all Advances comprising part of the same Borrowing are paid in whole or ratably in part.

          (d) Effect of Notice. All notices given pursuant to this Section 2.7 shall be irrevocable and binding upon the Borrower.

     Section 2.8 Breakage Costs. If (a) any payment of principal of any Eurocurrency Rate Advance is made other than on the last day of the Interest Period for such Advance as a result of any payment hereunder or the acceleration of the maturity of the Obligations pursuant to Article VIII or otherwise; (b) the Borrower fails to borrow, Convert, continue, repay or prepay any Eurocurrency Rate Advance on the date specified in any notice delivered pursuant hereto (other than default by a Lender), (c) the Borrower fails to make a principal or interest payment with respect to any Eurocurrency Rate Advance on the date such payment is due and payable, the Borrower shall, within 10 days of any written demand sent by any Lender to the Borrower (with a copy to the Administrative Agent), pay to the Administrative Agent for the account of such Lender any amounts (without duplication of any other amounts payable in respect of breakage costs) required to compensate such Lender for any additional losses, out-of-pocket costs or expenses which it may reasonably incur as a result of such payment or nonpayment, including any loss (including loss of anticipated profits), cost or expense incurred by reason of the liquidation or reemployment of deposits or other funds acquired by any Lender to fund or maintain such Advance.

     Section 2.9 Increased Costs.

          (a) Eurocurrency Rate Advances. If, due to either (i) introduction of or any change in or in the interpretation of any Legal Requirement (other than any change by way of imposition or increase of reserve requirements included in the calculation of the Eurocurrency Rate but including any change or introduction which would result in the failure of the Mandatory Cost Rate, as calculated hereunder, to represent the cost to any Lender of complying with the requirements of the Bank of England and/or the Financial Services Authority or the European Central Bank in relation to its making, funding or maintaining Eurocurrency Rate Advances), or (ii) compliance with any guideline or request from any central bank or other Governmental Authority (whether or not having the force of law), a Lender incurs increase cost related to the making or maintaining Eurocurrency Rate Advances (or maintaining its obligation to make any Eurocurrency Rate Advances), or the amount of any sum received or receivable by such Lender hereunder is reduced (whether of principal, interest or any other amount), then the Borrower shall from time to time, upon demand by such Lender (with a copy of such demand to the Administrative Agent), promptly pay to the Administrative Agent for the account of such Lender additional amounts (without duplication of any other amounts payable in respect of increased costs)

22

sufficient to compensate such Lender for such increased cost or reduction; provided, however, that, before making any such demand, each Lender agrees to use commercially reasonable efforts (consistent with its internal policy and legal and regulatory restrictions) to designate a different Lending Office if the making of such a designation would avoid the need for, or reduce the amount of, such increased cost and would not, in the reasonable judgment of such Lender, be otherwise disadvantageous to such Lender. A certificate as to the amount of such increased cost and detailing the calculation of such cost submitted to the Borrower and the Administrative Agent by such Lender at the time such Lender demands payment under this Section shall be conclusive and binding for all purposes, absent manifest error.

          (b) Capital Adequacy. If any Lender determines in good faith that compliance with any Legal Requirement or any guideline or request from any central bank or other Governmental Authority (whether or not having the force of law) implemented or effective after the date of this Agreement affects or would affect the amount of capital required or expected to be maintained by such Lender and that the amount of such capital is increased by or based upon the existence of Revolving Advances made by such Lender, the existence of such Lender’s commitment to lend and other commitments of this type, then, upon 30 days prior written notice by such Lender (with a copy of any such demand to the Administrative Agent), the Borrower shall promptly pay to the Administrative Agent for the account of such Lender, as the case may be, from time to time as specified by such Lender, additional amounts (without duplication of any other amounts payable in respect of increased costs) sufficient to compensate such Lender, in light of such circumstances, with respect to such Lender, to the extent that such Lender reasonably determines such increase in capital to be allocable to the existence of such Lender’s commitment to lend under this Agreement or its having made Revolving Advances. A certificate as to such amounts and detailing the calculation of such amounts submitted to the Borrower by such Lender shall be conclusive and binding for all purposes, absent manifest error.

     Section 2.10 Payments and Computations.

          (a) Payment Procedures. Except if otherwise set forth herein, the Borrower shall make each payment under this Agreement not later than 1:00 p.m. (Houston, Texas time) for payments due in Dollars and not later than 1:00 p.m. in the Applicable Time for payments due in Foreign Currencies, on the day when due in the Designated Currency as to outstanding Advances, and in Dollars as to all other amounts, to the Administrative Agent at its Lending Office (or such other location as the Administrative Agent shall designate in writing to the Borrower) in same day funds. The Administrative Agent will promptly thereafter cause to be distributed like funds relating to the payment of principal, interest or fees ratably (other than amounts payable solely to the Administrative Agent or a specific Lender pursuant to Section 2.3(c), 2.6(d), 2.6(e), 2.8, 2.9, 2.11, 2.12, 9.4 or 9.7 but after taking into account payments effected pursuant to Section 7.6) to the Lenders in accordance with each Lender’s Pro Rata Share for the account of their respective Lending Offices, and like funds relating to the payment of any other amount payable to any Lender to such Lender for the account of its Lending Office, in each case to be applied in accordance with the terms of this Agreement.

          (b) Computations. All computations of interest based on the Adjusted Prime Rate and interest on Eurocurrency Rate Advances denominated in Pounds Sterling shall be made by the Administrative Agent on the basis of a year of 365 or 366 days, as the case may be, and all computations of fees and interest based on the Eurocurrency Rate (other than as set forth above), Overnight Rate and the Federal Funds Rate shall be made by the Administrative Agent on the basis of a year of 360 days, in each case for the actual number of days (including the first day, but excluding the last day) occurring in the period for which such interest or fees are payable. Each determination by the Administrative Agent of an interest rate shall be conclusive and binding for all purposes, absent manifest error.

23

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

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

          (e) Application of Payments. Whenever any payment received by the Administrative Agent under this Agreement is insufficient to pay in full all amounts then due and payable under this Agreement and Notes, such payment shall be distributed and applied by the Administrative Agent and the Lenders in the following order: first, to the payment of fees and expenses due and payable to the Administrative Agent under and in connection with this Agreement or any other Credit Document; second, to the payment of all amount due and payable under Section 2.11(c), ratably among the Lenders in accordance with the aggregate amount of such payments owed to each such Lender; third, to the payment of all other fees due and payable under Section 2.3 ratably among the Lenders in accordance with their applicable Revolving Commitments; and fifth, to the payment of the interest accrued on and the principal amount of all of the Advances, regardless of whether any such amount is then due and payable, ratably among the Lenders in accordance with the aggregate accrued interest plus the aggregate principal amount owed to such Lender.

     Section 2.11 Taxes.

          (a) No Deduction for Certain Taxes. Any and all payments by the Borrower shall be made, in accordance with Section 2.10, free and clear of and without deduction for any and all present or future taxes, levies, imposts, deductions, charges or withholdings, and all liabilities with respect thereto, excluding, in the case of each Lender and the Administrative Agent, taxes imposed on its net income, and franchise taxes imposed on it in lieu thereof, by the jurisdiction under the laws of which such Lender or the Administrative Agent (as the case may be) is organized or any political subdivision of the jurisdiction (all such non-excluded taxes, levies, imposts, deductions, charges, withholdings and liabilities being hereinafter referred to as “Taxes”) and, in the case of each Lender, Taxes by the jurisdiction of such Lender’s Lending Office or any political subdivision of such jurisdiction. If the Borrower shall be required by law to deduct any Taxes from or in respect of any sum payable to any Lender or the Administrative Agent, (i) the sum payable shall be increased as may be necessary so that, after making all required deductions (including deductions applicable to additional sums payable under this Section 2.11), such Lender or the Administrative Agent (as the case may be) receives an amount equal to the sum it would have received had no such deductions been made; provided, however, that if the Borrower’s obligation to deduct Taxes is caused solely by such Lender’s or the Administrative Agent’s failure to provide the forms described in paragraph (e) of this Section 2.11 and such Lender or the Administrative Agent could have lawfully provided such forms, no such increase shall be required; (ii) the Borrower

24

shall make such deductions; and (iii) the Borrower shall pay the full amount deducted to the relevant taxation authority or other authority in accordance with applicable Legal Requirements.

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

          (c) Indemnification. The Borrower hereby indemnifies each Lender and the Administrative Agent for the full amount of Taxes or Other Taxes (including any Taxes or Other Taxes imposed by any jurisdiction on amounts payable under this Section 2.11) paid by such Lender or the Administrative Agent (as the case may be) and any liability (including interest and expenses) arising therefrom or with respect thereto, whether or not such Taxes or Other Taxes were correctly or legally asserted. Each payment required to be made by the Borrower in respect of this indemnification shall be made to the Administrative Agent for the benefit of any party claiming such indemnification within 30 days from the date the Borrower receives written demand detailing the calculation of such amounts therefor from the Administrative Agent or any such Lender (with a copy of such demand to the Administrative Agent).

          (d) Evidence of Tax Payments. The Borrower will pay prior to delinquency all Taxes payable in respect of any payment. Within 30 days after the date of any payment of Taxes, the Borrower will furnish to the Administrative Agent, at its address referred to in Section 9.2, the original or a certified copy of a receipt evidencing payment of such Taxes.

          (e) Status of Lenders.

     (i) Any Foreign Lender that is entitled to an exemption from or reduction of withholding tax under the law of the jurisdiction in which the Borrower is resident for tax purposes, or any treaty to which such jurisdiction is a party, with respect to payments hereunder or under any other Credit Document shall deliver to the Borrower (with a copy to the Administrative Agent), at the time or times prescribed by Legal Requirements applicable to such Lender or as reasonably requested by the Borrower or the Administrative Agent, such properly completed and executed documentation prescribed by Legal Requirements which such Lender is lawfully permitted to deliver as will permit such payments to be made without withholding or at a reduced rate of withholding. In addition, any Lender, if requested by the Borrower or Administrative Agent, shall deliver such other documentation prescribed by applicable law or reasonably requested by the Borrower or the Administrative Agent as will enable the Borrower or the Administrative Agent to determine whether or not such Lender is subject to backup withholding or information reporting requirements.

     (ii) Without limiting the generality of the foregoing, in the event that the Borrower is resident for tax purposes in the United States, any Foreign Lender shall deliver to Borrower and the Administrative Agent (in such number of copies as shall be requested by the recipient) on or prior to the date on which such Foreign Lender becomes a Lender under this Agreement (and from time to time thereafter promptly following the request of the Borrower or the Administrative Agent, but only if such Foreign Lender is legally entitled to do so), whichever of the following is applicable:

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

25

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

(C) in the case of a Foreign Lender claiming the benefits of the exemption for portfolio interest under section 881(c) of the Code, (x) a certificate to the effect that such Foreign Lender is not (A) a “bank” within the meaning of section 881(c)(3)(A) of the Code, (B) a “10 percent shareholder” of the applicable Borrower within the meaning of section 881(c)(3)(B) of the Code, or (C) a “controlled foreign corporation” described in section 881(c)(3)(C) of the Code and (y) duly completed copies of Internal Revenue Service Form W-8BEN, or

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

     (iii) Without limiting the obligations of the Lenders set forth above regarding delivery of certain forms and documents to establish each Lender’s status for U.S. withholding tax purposes, each Lender agrees promptly to deliver to the Administrative Agent or the Borrower, as the Administrative Agent or the Borrower shall reasonably request, on or prior to the Closing Date, and in a timely fashion thereafter following such reasonable request therefor, such other documents and forms required by any relevant taxing authorities under the Legal Requirements of any other jurisdiction, duly executed and completed by such Lender, as are required under such Legal Requirements to confirm such Lender’s entitlement to any available exemption from, or reduction of, applicable withholding taxes in respect of all payments to be made to such Lender outside of the United States by the Borrower pursuant to this Agreement or otherwise to establish such Lender’s status for withholding tax purposes in such other jurisdiction. Each Lender shall promptly notify the Administrative Agent of any change in circumstances which would modify or render invalid any such claimed exemption or reduction. Additionally, the Borrower shall promptly deliver to the Administrative Agent or any Lender, as the Administrative Agent or such Lender shall reasonably request, on or prior to the Closing Date, and in a timely fashion thereafter, such documents and forms required by any relevant taxing authorities under the Legal Requirements of any jurisdiction, duly executed and completed by the Borrower, as are required to be furnished by such Lender or the Administrative Agent under such Legal Requirements in connection with any payment by the Administrative Agent or any Lender of Taxes or Other Taxes, or otherwise in connection with the Credit Documents, with respect to such jurisdiction.

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

26

          (g) Mitigation. Each Lender agrees to use commercially reasonable efforts (consistent with its internal policies and legal and regulatory restrictions) to select a jurisdiction for its Lending Office or change the jurisdiction of its Lending Office, as the case may be, so as to avoid the imposition of any Taxes or Other Taxes or to eliminate or reduce the payment of any additional sums under this Section 2.11 or to eliminate or reduce the payment of interest due to it which is based on the Mandatory Cost Rate; provided, that no such selection or change of jurisdiction for its Lending Office shall be made if, in the reasonable judgment of such Lender, such selection or change would be disadvantageous to such Lender.

     Section 2.12 Illegality. If any Lender shall notify the Administrative Agent and the Borrower that the introduction of or any change in or in the interpretation of any Legal Requirement makes it unlawful, or that any central bank or other Governmental Authority asserts that it is unlawful for such Lender or its Lending Office to perform its obligations under this Agreement to maintain any Eurocurrency Rate Advances of such Lender then outstanding hereunder or any Governmental Authority has imposed material restrictions on the authority of such Lender to purchase or sell, or take deposits of, Dollars or any Foreign Currency in the applicable interbank market, then, notwithstanding anything herein to the contrary, the Borrower shall, if demanded by such Lender in its notice, no later than 12:00 p.m. (Houston, Texas time), (a) if not prohibited by any Legal Requirement to maintain such Eurocurrency Rate Advances for the duration of the Interest Period, on the last day of the Interest Period for each outstanding Eurocurrency Rate Advance of such Lender or (b) if prohibited by any Legal Requirement to maintain such Eurocurrency Rate Advances for the duration of the Interest Period, on the second Business Day following its receipt of such notice from such Lender, then (i) with respect to Revolving Advances denominated in a Foreign Currency, prepay such Eurocurrency Rate Advances of such Lender then outstanding and which are denominated in such affected currency or currencies together with all accrued interest on the amount so prepaid, and amounts, if any, required to be paid pursuant to Section 2.8 as a result of such prepayment being made on such date, and (ii) with respect to Revolving Advances denominated in Dollars, Convert all such Eurocurrency Rate Advances of such Lender then outstanding to Prime Rate Advances and pay accrued interest on the principal amount Converted to the date of such Conversion and amounts, if any, required to be paid pursuant to Section 2.8 as a result of such Conversion being made on such date. Each Lender agrees to use commercially reasonable efforts (consistent with its internal policies and legal and regulatory restrictions) to designate a different Lending Office if the making of such designation would avoid the effect of this paragraph and would not, in the reasonable judgment of such Lender, be otherwise disadvantageous to such Lender.

     Section 2.13 Reserved.

     Section 2.14 Sharing of Payments, Etc. If any Lender shall obtain any payment (whether voluntary, involuntary, through the exercise of any right of set-off or otherwise) on account of its Advances in excess of its Pro Rata Share of payments on account of the Advances obtained by all the Lenders, then such Lender shall notify the Administrative Agent and the other Lenders and forthwith purchase from the other Lenders, such participations in the Advances made by them as shall be necessary to cause such purchasing Lender to share the excess payment ratably in accordance with the requirements of this Agreement with each of them; provided, however, that if all or any portion of such excess payment is thereafter recovered from such purchasing Lender, such purchase from each Lender shall be rescinded and such Lender shall repay to the purchasing Lender the purchase price to the extent of such Lender’s ratable share (according to the proportion of (a) the amount of the participation sold by such Lender to the purchasing Lender as a result of such excess payment to (b) the total amount of such excess payment) of such recovery, together with an amount equal to such Lender’s ratable share (according to the proportion of (i) the amount of such Lender’s required repayment to the purchasing Lender to (ii) the total amount of all such required repayments to the purchasing Lender) of any interest or other amount paid or payable by

27

the purchasing Lender in respect of the total amount so recovered. The Borrower agrees that any Lender so purchasing a participation from another Lender pursuant to this Section 2.14 may, to the fullest extent permitted by law, unless and until rescinded as provided above, exercise all its rights of payment (including the right of set-off) with respect to such participation as fully as if such Lender were the direct creditor of the Borrower in the amount of such participation.

     Section 2.15 Reserved. Section 2.16 Lender Replacement.

          (a) Right to Replace. The Borrower shall have the right to replace each Lender affected by a condition under Section 2.2(c)(v), 2.2(c)(viii), 2.9, 2.11 or 2.12 for more than 30 days, each Lender that is a Non-Consenting Lender under Section 2.19, and each Lender that is due interest based on the Mandatory Cost Rate (each such affected Lender, an “Affected Lender”) in accordance with the procedures in this Section 2.16 and provided that no reduction of the total Revolving Commitments occurs as a result thereof.

          (b) First Right of Refusal; Replacement.

     (i) Upon the occurrence of any condition permitting the replacement of a Lender, each Lender which is not an Affected Lender shall have the right, but not the obligation, to elect to increase its respective Revolving Commitment by an amount not to exceed the amount of the Revolving Commitments of the Affected Lenders, which election shall be made by written notice from each such Lender to the Administrative Agent and the Borrower given within 30 days after the date such condition occurs specifying the amount of such proposed increase in such Lender’s Revolving Commitment.

     (ii) If the aggregate amount of the proposed increases in Revolving Commitments of all such Lenders making such an election is in excess of the Revolving Commitments of the Affected Lenders, (A) the Revolving Commitments of the Affected Lenders shall be allocated pro rata among such Lenders based on the respective amounts of the proposed increases to Revolving Commitments elected by each of such Lenders, and (B) the respective commitments of such Lenders shall be increased by the respective amounts as so allocated so that after giving effect to such termination and increases the aggregate amount of the Revolving Commitments of the Lenders will be the same as prior to such termination.

     (iii) If the aggregate amount of the proposed increases to Revolving Commitments of all Lenders making such an election is less than the Revolving Commitments of the Affected Lenders, (A) the respective Revolving Commitments of such Lenders shall be increased by the respective amounts of their proposed increases, and (B) the Borrower shall add additional Lenders which are Eligible Assignees to this Agreement to replace such Affected Lenders, which additional Lenders would have aggregate Revolving Commitments no greater than those of the Affected Lenders minus the amounts thereof assumed by the other Lenders pursuant to such increases.

          (c) Procedure. Any assumptions of Revolving Commitments pursuant to this Section 2.16 shall be made by the purchasing Lender or Eligible Assignee and the selling Lender by entering into an Assignment and Assumption and by following the procedures in Section 9.6 for adding a Lender. In connection with the increase of the Revolving Commitments of any Lender pursuant to the

28

foregoing paragraph (b), each Lender with an increased Revolving Commitment shall purchase from the Affected Lenders at par such Lender’s ratable share of the outstanding Advances of the Affected Lenders.

     Section 2.17 Currency Fluctuations and Mandatory Prepayments.

          (a) Not later than 1:00 p.m., Houston, Texas time, on each Computation Date, the Administrative Agent shall determine the Exchange Rate as of such Computation Date and give notice thereof to the Borrower and each Lender. The Exchange Rate so determined shall become effective on the first Business Day after such Computation Date and shall remain effective through the next succeeding Computation Date.

          (b) If, on any Computation Date, the Dollar Amount of the aggregate outstanding principal amount of Revolving Advances exceeds an amount equal to 102% of the aggregate Revolving Commitments then in effect, then the Administrative Agent shall give notice thereof to the Borrower and the Lenders, and the Borrower shall within five (5) Business Days thereafter prepay Advances such that after giving effect to such prepayment of Advances, the Dollar Amount of the aggregate outstanding principal amount of Revolving Advances does not exceed the aggregate Revolving Commitments then in effect.

          (c) If any currency shall cease to be an Agreed Currency as provided in the last sentence of the definition of “Agreed Currency”, then promptly, but in any event within five (5) Business Days of receipt of the notice from the Administrative Agent provided for in such sentence, the Borrower shall repay all Advances funded and denominated in such affected currency or Convert such Advances into Advances in Dollars or another Agreed Currency, subject to the other terms set forth in Article II.

          (d) Each prepayment pursuant to this Section 2.17 shall be accompanied by accrued interest on the amount prepaid to the date of such prepayment and amounts, if any, required to be paid pursuant to Section 2.8 as a result of such prepayment being made on such date.

          (e) Each payment of any Advance pursuant to this Section 2.17 or any other provision of this Agreement shall be made in a manner such that all Advances comprising part of the same Borrowing are paid in whole or ratably in part and each payment of an Advance shall be made in the Designated Currency in which such Advance was funded.

     Section 2.18 Market Disruption. Notwithstanding the satisfaction of all conditions referred to herein with respect to any proposed Borrowing consisting of Eurocurrency Advances denominated in any Foreign Currencies, if there shall occur on or prior to the date of such Borrowing any change in national or international financial, political or economic conditions or currency exchange rates or exchange controls which would in the reasonable opinion of the Administrative Agent or the Majority Lenders, make it impracticable for such Borrowing to be denominated in the Agreed Currency designated by the Borrower, then the Administrative Agent shall forthwith give notice thereof to the Borrower and the Lenders, and such Advances shall not thereafter be denominated and funded in such Agreed Currency but shall, except as otherwise set forth in Article II, be made on such date in Dollars, in an aggregate principal amount equal to the Dollar Amount of the aggregate principal amount specified in the related Notice of Borrowing, as the case may be, as Prime Rate Advances to the Borrower, unless the Borrower notifies the Administrative Agent at least one Business Day before such date that it elects not to borrow on such date.

29

     Section 2.19 Extension of Maturity Date.

          (a) Not earlier than 45 days prior to the Maturity Date, then in effect, nor later than 30 days prior to the Maturity Date, then in effect, the Borrower may, upon notice to the Administrative Agent (which shall promptly notify the Lenders), request a one year extension of the Maturity Date then in effect (the “Present Maturity Date”). This option may be exercised only once. No earlier than 30 days prior to the Present Maturity Date but no later than 15 days prior to the Present Maturity Date, each Lender shall notify the 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 Agent shall promptly notify the Borrower and the Lenders of the Lenders’ responses.

          (b) The Maturity Date shall be extended only if the Majority Lenders have consented thereto (the “Consenting Lenders”) and only if the Revolving Commitments of the Consenting Lenders are at least equal to the outstanding principal amount of all Revolving Advances, after giving effect to the prepayment of Revolving Advances to Non-Consenting Lenders.

Without limitation of the foregoing, each Lender agrees to (a) reimburse the Administrative Agent promptly upon demand for its ratable share of any out-of-pocket expenses (including counsel fees) incurred by the Administrative Agent in connection with the preparation, execution, delivery, modification or amendment of this Agreement or any other Credit Document, to the extent that the Administrative Agent is not reimbursed for such expenses by the Borrower and (b) reimburse the Administrative Agent promptly upon demand for its ratable share of any out-of-pocket expenses (including counsel fees) incurred by the Administrative Agent in connection with the administration or enforcement (whether through negotiations, legal proceedings or otherwise) of, or legal advice in respect of rights or responsibilities under, this Agreement or any other Credit Document, to the extent that the Administrative Agent is not reimbursed for such expenses by the Borrower.

If no successor Administrative Agent shall have been so appointed, and shall have accepted such appointment, within 30 days after the retiring or removed Administrative Agent’s giving of notice of resignation or the Majority Lenders’ removal of the retiring Administrative Agent, then the retiring or removed Administrative Agent may, on behalf of the Lenders and the Borrower, appoint a successor Administrative Agent, which shall be a commercial bank meeting the financial requirements of an Eligible Assignee.

46

thereupon succeed to and become vested with all the rights, powers, privileges and duties of the retiring or removed Administrative Agent, and the retiring or removed Administrative Agent shall be discharged from its duties and obligations under this Agreement and the other Credit Documents.

48

provided in this Agreement and the other Credit Documents are cumulative and not exclusive of any remedies provided by law.

     Section 9.4 Costs and Expenses. The Borrower agrees to pay on demand all out-of-pocket costs and expenses of the Administrative Agent in connection with the preparation, execution, delivery, administration, modification and amendment of this Agreement, the Notes and the other Credit Documents including (a) all reasonable out-of-pocket costs and expenses, if any, of the Administrative Agent, each Arranger, and each Lender (including reasonable counsel fees and expenses of the Administrative Agent, each Arranger, and each Lender) in connection with the enforcement (whether through negotiations, legal proceedings or otherwise) of this Agreement and the other Credit Documents after an Event of Default has occurred and is continuing, and (b) to the extent not included in the foregoing, the costs of any Uniform Commercial Code financing statement or continuation statement, and any related title or Uniform Commercial Code search conducted subsequent to such recordation, and other costs usual and customary in connection with the taking of a Lien.

     Section 9.5 Binding Effect. This Agreement shall become effective when it shall have been executed by the Borrower and the Administrative Agent, and when the Administrative Agent shall have, as to each Lender, either received a counterpart hereof executed by such Lender or been notified by such Lender that such Lender has executed it and thereafter shall be binding upon and inure to the benefit of the Borrower, the Administrative Agent, the Arrangers, and each Lender and their respective successors and assigns, except that the Borrower shall not have the right to assign its rights or delegate its duties under this Agreement or any interest in this Agreement without the prior written consent of each Lender.

     Section 9.6 Lender Assignments and Participations.

          (a) Assignments. Any Lender may assign to one or more banks or other entities all or any portion of its rights and obligations under this Agreement (including all or a portion of its Revolving Commitment, the Advances owing to it, the Notes held by it, if any); provided, however, that (i) each such assignment shall be of a constant, and not a varying, percentage of all of such Lender’s rights and obligations under this Agreement as a Lender and shall involve a ratable assignment of such Lender’s Revolving Commitment and such Lender’s Revolving Advances and shall be in an amount not less than $5,000,000, (ii) the amount of the resulting Revolving Commitment and Revolving Advances of the assigning Lender (unless it is assigning all its Revolving Commitment) and the assignee Lender pursuant to each such assignment (determined as of the date of the Assignment and Acceptance with respect to such assignment) shall in no event be less than $10,000,000, (iii) each such assignment shall be to an Eligible Assignee, (iv) the parties to each such assignment shall execute and deliver to the Administrative Agent, for its acceptance and recording in the Register, an Assignment and Acceptance, together with the applicable Notes, if any, subject to such assignment, (v) each Eligible Assignee shall pay to the Administrative Agent a $4,000 administrative fee; and (vi) the Administrative Agent shall promptly deliver a copy of the fully executed Assignment and Acceptance to the Administrative Agent. Upon such execution, delivery, acceptance and recording, from and after the effective date specified in each Assignment and Acceptance, which effective date shall be at least three Business Days after the execution thereof, (A) the assignee thereunder shall be a party hereto for all purposes and, to the extent that rights and obligations hereunder have been assigned to it pursuant to such Assignment and Acceptance, have the rights and obligations of a Lender hereunder and (B) such Lender thereunder shall, to the extent that rights and obligations hereunder have been assigned by it pursuant to such Assignment and Acceptance, relinquish its rights and be released from its obligations under this Agreement (and, in the case of an Assignment and Acceptance covering all or the remaining portion of such Lender’s rights and obligations under this Agreement, such Lender shall cease to be a party hereto) but shall continue to be entitled to the benefits of Sections 2.8, 2.9, 2.11, 9.4, 9.7 and 9.16 with respect to facts and

49

circumstances occurring prior to the effective date of such assignment. Notwithstanding anything herein to the contrary, any Lender may assign, as collateral or otherwise, any of its rights under the Credit Documents to any Federal Reserve Bank.

          (b) Term of Assignments. By executing and delivering an Assignment and Acceptance, the Lender thereunder and the assignee thereunder confirm to and agree with each other and the other parties hereto as follows: (i) other than as provided in such Assignment and Acceptance, such Lender makes no representation or warranty and assumes no responsibility with respect to any statements, warranties or representations made in or in connection with this Agreement or the execution, legality, validity, enforceability, genuineness, sufficiency or value of this Agreement or any other instrument or document furnished pursuant hereto; (ii) such Lender makes no representation or warranty and assumes no responsibility with respect to the financial condition of the Borrower or the performance or observance by the Borrower of any of its obligations under this Agreement or any other instrument or document furnished pursuant hereto; (iii) such assignee confirms that it has received a copy of this Agreement, together with copies of the financial statements referred to in Section 4.6 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) such assignee will, independently and without reliance upon the Administrative Agent, such Lender or any other Lender and based on such documents and information as it shall deem appropriate at the time, continue to make its own credit decisions in taking or not taking action under this Agreement; (v) such assignee appoints and authorizes the Administrative Agent to take such action as agent on its behalf and to exercise such powers under this Agreement as are delegated to the Administrative Agent by the terms hereof, together with such powers as are reasonably incidental thereto; and (vi) such assignee agrees that it will perform in accordance with their terms all of the obligations which by the terms of this Agreement are required to be performed by it as a Lender.

          (c) The Register. The Administrative Agent shall maintain at its respective address referred to in Section 9.2 a copy of each Assignment and Acceptance delivered to and accepted by it and a register for the recordation of the names and addresses of the respective Lenders and the Revolving Commitment and principal amount of the Advances owing to, each Lender from time to time (the “Register”). The entries in the Register shall be conclusive and binding for all purposes, absent manifest error, and the Borrower, the Administrative Agent and the Lenders may treat each Person whose name is recorded in the Register as a Lender hereunder for all purposes of this Agreement. At any reasonable time and from time to time upon reasonable prior notice, the Register shall be available (i) for inspection by the Borrower and (ii) for inspection by each Lender as to its Revolving Commitment and principal amount of Advances owing to it.

          (d) Procedures. Upon its receipt of an Assignment and Acceptance executed by a Lender and an Eligible Assignee, together with the Notes, if any, subject to such assignment, the Administrative Agent shall, if such Assignment and Acceptance has been completed and is in substantially the form of the attached Exhibit A, (i) accept such Assignment and Acceptance, (ii) record the information contained therein in the Register, and (iii) give prompt notice thereof to the Borrower.

          (e) Participations. Each Lender may sell participations to one or more banks or other entities in or to all or a portion of its rights and obligations under this Agreement (including all or a portion of its Revolving Commitment, the Advances owing to it, and the Notes held by it, if any); provided, however, that (i) such Lender’s obligations under this Agreement (including its Revolving Commitment to the Borrower hereunder) shall remain unchanged, (ii) such Lender shall remain solely responsible to the other parties hereto for the performance of such obligations, (iii) such Lender shall remain the holder of any such Obligations for all purposes of this Agreement, (iv) the Borrower, the Administrative Agent and the Lenders shall continue to deal solely and directly with such Lender in

50

connection with such Lender’s rights and obligations under this Agreement, (v) such Lender shall not require the participant’s consent to any matter under this Agreement, except for change in the principal amount of any Obligation in which the participant has an interest, reductions in fees or interest, or extending the Maturity Date, and (vi) such Lender shall give prompt prior notice to the Borrower of each such participation to be sold by such Lender. The Borrower hereby agrees that participants shall have the same rights under Sections 2.8, 2.9, 2.11(c), 9.4 and 9.7 hereof as the Lender to the extent of their respective participations. Notwithstanding the foregoing and so long as no Event of Default has occurred and is continuing, upon the receipt of notice by the Borrower of the sale of a participation by any Lender to one or more banks or other entities (other than an Affiliate of such Lender) in or to all or a portion of its rights and obligations under this Agreement (each such bank or other entity, a “Proposed Participant”), the Borrower shall have the right, but not the obligation, to select additional lenders to replace such Proposed Participant on the same terms and conditions as the Proposed Participant upon prompt written notice from the Borrower to the Administrative Agent and the Lender selling such participation. The Borrower shall have ten days from the date of its receipt of notice of the proposed sale of such participation to the Proposed Participant to select replacement lenders to replace such Proposed Participant. If the Borrower does not select any replacement lenders or does not elect to select any replacement lenders the applicable Lender may sell such participation to the Proposed Participant.

     Section 9.7 Indemnification. The Borrower shall indemnify the Administrative Agent, the Arrangers, and the Lenders (including any lender which was a Lender hereunder prior to any full assignment of its Revolving Commitment), and each affiliate thereof and their respective directors, officers, employees and agents from, and discharge, release, and hold each of them harmless against, any and all losses, liabilities, claims or damages to which any of them may become subject, insofar as such losses, liabilities, claims or damages arise out of or result from (i) the execution or delivery of this Agreement or any agreement or instrument contemplated hereby, the performance by the parties hereto of their respective obligations hereunder or the consummation of the Merger or any other transactions contemplated hereby, (ii) any actual or proposed use by the Borrower or any Affiliate of the Borrower of the proceeds of any Revolving Advance, (iii) any breach by the Borrower of any provision of this Agreement or any other Credit Document, (iv) any Environmental Claim or requirement of Environmental Laws concerning or relating to the present or previously-owned or operated properties, or the operations or business, of the Borrower or any of its Subsidiaries, and (v) any investigation, litigation or other proceeding (including any threatened investigation or proceeding) relating to the foregoing, and the Borrower shall reimburse the Administrative Agent, each Arranger, and each Lender, and each affiliate thereof and their respective directors, officers, employees and agents, upon demand for any reasonable out-of-pocket expenses (including legal fees) incurred in connection with any such losses, liabilities, claims, damages, investigation, litigation, Environmental Claim or requirement, or other proceeding; and EXPRESSLY INCLUDING ANY SUCH LOSSES, LIABILITIES, CLAIMS, DAMAGES, OR EXPENSE INCURRED BY REASON OF THE PERSON BEING INDEMNIFIED’S OWN NEGLIGENCE, BUT EXCLUDING ANY SUCH LOSSES, LIABILITIES, CLAIMS, DAMAGES OR EXPENSES FOUND BY A FINAL JUDGMENT BY A COURT OF COMPETENT JURISDICTION TO HAVE RESULTED FROM THE GROSS NEGLIGENCE OR WILLFUL MISCONDUCT OF THE PERSON TO BE INDEMNIFIED.

     Section 9.8 Execution in Counterparts. This Agreement may be executed in any number of counterparts and by different parties hereto in separate counterparts, each of which when so executed shall be deemed to be an original and all of which taken together shall constitute one and the same agreement.

     Section 9.9 Survival of Representations, etc. All representations and warranties contained in this Agreement or made in writing by or on behalf of the Borrower in connection herewith shall survive

51

the execution and delivery of this Agreement and the Credit Documents, the making of the Advances and any investigation made by or on behalf of the Lenders, none of which investigations shall diminish any Lender’s right to rely on such representations and warranties. All obligations of the Borrower provided for in Sections 2.8, 2.9, 2.11, 9.4, 9.7 and 9.16 shall survive any termination of this Agreement and repayment in full of the Obligations.

     Section 9.10 Severability. In case one or more provisions of this Agreement or the other Credit Documents shall be invalid, illegal or unenforceable in any respect under any applicable Legal Requirement, the validity, legality and enforceability of the remaining provisions contained herein or therein shall not be affected or impaired thereby.

     Section 9.11 Usury Not Intended. It is the intent of the Borrower and each Lender in the execution and performance of this Agreement and the other Credit Documents to contract in strict compliance with applicable usury laws, including conflicts of law concepts, governing the Advances of each Lender including such applicable Legal Requirements of the State of Texas and the United States of America from time to time in effect. In furtherance thereof, each Lender and the Borrower stipulate and agree that none of the terms and provisions contained in this Agreement or the other Credit Documents shall ever be construed to create a contract to pay, as consideration for the use, forbearance or detention of money, interest at a rate in excess of the Maximum Rate and that for purposes hereof “interest” shall include the aggregate of all charges which constitute interest under such laws that are contracted for, charged or received under this Agreement. In the event that the Obligations are accelerated by reason of any election of the holder thereof resulting from any Event of Default under this Agreement or otherwise, or in the event of any required or permitted prepayment, then such consideration that constitutes interest may never include more than the Maximum Rate and excess interest, if any, provided for in this Agreement or otherwise shall be canceled automatically as of the date of such acceleration or prepayment and, if theretofore paid, shall be credited on the applicable Obligations (or, if the applicable Obligations shall have been paid in full, refunded to the Borrower). The provisions of this Section shall control over all other provisions of this Agreement or the other Credit Documents which may be in apparent conflict herewith.

     Section 9.12 Confidentiality. None of the Administrative Agent or Lenders shall disclose any Confidential Information to any Person without the consent of the Borrower, other than (a) to the Administrative Agent’s or Lender’s Affiliates and their officers, directors, employees, agents and advisors, (b) to actual or prospective Eligible Assignees and participants and their officers, directors, employees, agents and advisors, (c) to any direct, indirect, actual or prospective counterparty (and its advisor) to any swap, derivative or securitization transaction related to the obligations under this Agreement, and then, in any event, only on a confidential basis, (d) as required by any law, rule or regulation or judicial process, (e) as requested or required by any state, Federal or foreign authority or examiner (including the National Association of Insurance Commissioners or any similar organization or quasi-regulatory authority) regulating such Lender or Administrative Agent, or to insurers, insurance brokers or direct or indirect providers of credit protection when required by it, provided that, prior to any such disclosure, such Person shall undertake to preserve the confidentiality of any Confidential Information relating to the Borrower received by it from such Lender or Administrative Agent, (f) to any rating agency when required by it, provided that, prior to any such disclosure, such rating agency shall undertake to preserve the confidentiality of any Confidential Information relating to the Borrower received by it from such Lender or Administrative Agent, (g) in connection with any litigation or proceeding to which Administrative Agent or such Lender or any of its Affiliates may be a party or (h) in connection with the exercise of any right or remedy under this Agreement or any other Credit Document. NOTWITHSTANDING ANYTHING TO THE CONTRARY CONTAINED HEREIN, nothing in this Agreement shall (a) restrict the Administrative Agent or any Lender from providing

52

information to any bank or other regulatory or governmental authorities, including the Federal Reserve Board and its supervisory staff; (b) require or permit the Administrative Agent or any Lender to disclose to the Borrower that any information will be or was provided to the Federal Reserve Board or any of its supervisory staff; or (c) require or permit the Administrative Agent or any Lender to inform the Borrower of a current or upcoming Federal Reserve Board examination or any nonpublic Federal Reserve Board supervisory initiative or action.

     Section 9.13 Governing Law; Submission to Jurisdiction.

     (a) This Agreement, the Notes and the other Credit Documents shall be governed by, and construed and enforced in accordance with, the laws of the State of New York without regard to conflict of law principles thereof.

     (b) Any legal action or proceeding with respect to this Agreement or any other Credit Document may be brought in the courts of the state of New York sitting in New York City or of the United States for the Southern District of such state, and by execution and delivery of this Agreement, the Borrower, the Administrative Agent and each Lender consents, for itself and in respect of its property, to the non-exclusive jurisdiction of those courts. The Borrower, the Administrative Agent and each Lender irrevocably waives any objection, including any objection to the laying of venue or based on the grounds of forum non conveniens, which it may now or hereafter have to the bringing of any action or proceeding in such jurisdiction in respect of this Agreement or any other Credit Document or other document related thereto.

     (c) The Borrower irrevocably consents to the service of any and all process in any such action or proceeding by the mailing of copies of such process to it at the address specified for it in this Agreement.

     (d) Nothing in this Section 9.13 shall affect the right of the Administrative Agent or any other Lender to serve legal process in any other manner permitted by law or affect the right of the Administrative Agent or any other Lender to bring any action or proceeding against the Borrower in the courts of any other jurisdiction.

     Section 9.14 Waiver of Jury Trial. The Borrower, the Lenders and the Administrative Agent hereby irrevocably waive any and all right to trial by jury in respect of any legal proceeding, directly or indirectly (whether sounding in tort, contract or otherwise), arising out of or relating to this Agreement, any other Credit Document, any of the transactions contemplated hereby, or the relationship established hereunder.

     Section 9.15 Waiver of Consequential Damages. To the extent permitted by applicable law, Borrower shall not assert, and the Borrower hereby waives, any claim against any other party hereto and each affiliate thereof and their respective directors, officers, employees and agents, on any theory of liability, for special, indirect, consequential or punitive damages (as opposed to direct or actual damages) arising out of, in connection with, or as a result of, this Agreement or any other Credit Document, the Merger, any Advance or Letter of Credit or the use of the proceeds thereof.

     Section 9.16 Judgment Currency. If for the purposes of obtaining judgment in any court it is necessary to convert a sum due from the Borrower hereunder in the currency expressed to be payable herein (the “specified currency”) into another currency, the parties hereto agree, to the fullest extent that

53

they may effectively do so, that the rate of exchange used shall be that at which in accordance with usual and customary banking procedures the Administrative Agent could purchase the specified currency with such other currency at any of the Administrative Agent’s offices in the United States of America on the Business Day preceding that on which final, non-appealable judgment is given. The obligations of the Borrower in respect of any sum due to any Lender or the Administrative Agent hereunder shall, notwithstanding any judgment in a currency other than the specified currency, be discharged only to the extent that on the Business Day following receipt by such Lender or the Administrative Agent (as the case may be) of any sum adjudged to be so due in such other currency such Lender or the Administrative Agent (as the case may be) may in accordance with normal, reasonable banking procedures purchase the specified currency with such other currency. If the amount of the specified currency so purchased is less than the sum originally due to such Lender or the Administrative Agent, as the case may be, in the specified currency, the Borrower agrees, to the fullest extent that it may effectively do so, as a separate obligation and notwithstanding any such judgment, to indemnify such Lender or the Administrative Agent, as the case may be, against such loss, and if the amount of the specified currency so purchased exceeds (a) the sum originally due to any Lender or the Administrative Agent, as the case may be, in the specified currency and (b) any amounts shared with other Lenders as a result of allocations of such excess as a disproportionate payment to such Lender under Section 2.14, each Lender or the Administrative Agent, as the case may be, agrees to promptly remit such excess to the Borrower. All obligations of the Borrower provided in this Section 9.16 shall survive any termination of this Agreement and repayment in full of the Obligations.

     Section 9.17 Headings Descriptive. The headings of the several Sections and paragraphs of the Agreement are inserted for convenience only and shall not in any way affect the meaning or construction of any provision of this Agreement.

     Section 9.18 USA Patriot Act. Each Lender that is subject to the Act (as hereinafter defined) and the Administrative Agent (for itself and not on behalf of any Lender) hereby notifies the Borrower that pursuant to the requirements of the USA Patriot Act (Title III of Pub. L. 107-56 (signed into law October 26, 2001)) (the “Act”), it is required to obtain, verify and record information that identifies the Borrower, which information includes the name and address of the Borrower and other information that will allow such Lender or the Administrative Agent, as applicable, to identify the Borrower in accordance with the Act.

This written agreement and the Credit Documents, as defined in this Agreement, represent the final agreement among the parties and may not be contradicted by evidence of prior, contemporaneous, or subsequent oral agreements of the parties.

SCHEDULE 1.1(b)

MANDATORY COST RATE

1. The Mandatory Cost Rate (to the extent applicable) is an addition to the interest rate otherwise payable to compensate Lenders for the cost of compliance with:

(a)	the requirements of the Bank of England and/or the Financial Services Authority (or, in either case, any other authority which replaces all or any of its functions); or
(b)	the requirements of the European Central Bank.

2.	On the first day of each Interest Period (or as soon as possible thereafter) the Administrative Agent shall calculate, as a percentage rate, a rate (the “Additional Cost Rate”) for each Lender, in accordance with the paragraphs set out below. The Mandatory Cost Rate will be calculated by the Administrative Agent as a weighted average of the Lenders’ Additional Cost Rates (weighted in proportion to the percentage participation of each Lender in the relevant Advance) and will be expressed as a percentage rate per annum. The Administrative Agent will, at the request of the Borrower or any Lender, deliver to the Borrower or such Lender as the case may be, a statement setting forth the calculation of any Mandatory Cost Rate.
3.	The Additional Cost Rate for any Lender lending from a Lending Office in a Participating Member State will be the percentage notified by that Lender to the Administrative Agent. This percentage will be certified by such Lender in its notice to the Administrative Agent to be its reasonable determination of the cost (expressed as a percentage of such Lender’s participation in all Advances made from such Lending Office) of complying with the minimum reserve requirements of the European Central Bank in respect of Advances made from that Lending Office.
4.	The Additional Cost Rate for any Lender lending from a Lending Office in the United Kingdom will be calculated by the Administrative Agent as follows:

(a) in relation to any Advance in Pounds Sterling:

AB+C(B-D)+E x 0.01	per cent per annum
100 – (A+C)

(b) in relation to any Advance in any currency other than Pounds Sterling:

E x 0.01	per cent per annum
300

Where:

“A”	is the percentage of Eligible Liabilities (assuming these to be in excess of any stated minimum) which that Lender is from time to time required to maintain as an interest free cash ratio deposit with the Bank of England to comply with cash ratio requirements.
“B”	is the percentage rate of interest (excluding the Applicable Margin, the Mandatory Cost Rate and any interest charged on overdue amounts pursuant to the first sentence of Section 2.6(b)) payable for the relevant Interest Period of such Advance.

Schedule 1.1(b)

“C”	is the percentage (if any) of Eligible Liabilities which that Lender is required from time to time to maintain as interest bearing Special Deposits with the Bank of England.
“D”	is the percentage rate per annum payable by the Bank of England on interest bearing Special Deposits.
“E”	is designed to compensate Lenders for amounts payable under the Fees Rules and is calculated by the Administrative Agent as being the average of the most recent rates of charge supplied by the Lenders to the Administrative Agent pursuant to paragraph 7 below and expressed in pounds per £1,000,000.

5. For the purposes of this Schedule:

(a)	“Eligible Liabilities” and “Special Deposits” have the meanings given to them from time to time under or pursuant to the Bank of England Act 1998 or (as may be appropriate) by the Bank of England;
(b)	“Fees Rules” means the rules on periodic fees contained in the FSA Supervision Manual or such other law or regulation as may be in force from time to time in respect of the payment of fees for the acceptance of deposits;
(c)	“Fee Tariffs” means the fee tariffs specified in the Fees Rules under the activity group A.1 Deposit acceptors (ignoring any minimum fee or zero rated fee required pursuant to the Fees Rules but taking into account any applicable discount rate); and
(d)	“Tariff Base” has the meaning given to it in, and will be calculated in accordance with, the Fees Rules.

6.	In application of the above formulae, A, B, C and D will be included in the formulae as figures and not as percentages (i.e. 5% will be included in the formula as 5 and not as 0.05). A negative result obtained by subtracting D from B shall be taken as zero. The resulting figures shall be rounded to four decimal places.
7.	If requested by the Administrative Agent or the Borrower, each Lender with a Lending Office in the United Kingdom or a Participating Member State shall, as soon as practicable after publication by the Financial Services Authority, supply to the Administrative Agent and the Borrower, the rate of charge payable by such Lender to the Financial Services Authority pursuant to the Fees Rules in respect of the relevant financial year of the Financial Services Authority (calculated for this purpose by such Lender as being the average of the Fee Tariffs applicable to such Lender for that financial year) and expressed in pounds per £1,000,000 of the Tariff Base of such Lender.
8.	Each Lender shall supply any information required by the Administrative Agent for the purpose of calculating its Additional Cost Rate. In particular, but without limitation, each Lender shall supply the following information in writing on or prior to the date on which it becomes a Lender:

(a) the jurisdiction of the Lending Office out of which it is making available its participation in the relevant Advance; and

Schedule 1.1(b)

(b) any other information that the Administrative Agent may reasonably require for such purpose.

Each Lender shall promptly notify the Administrative Agent in writing of any change to the information provided by it pursuant to this paragraph.

9.	The percentages of each Lender for the purpose of A and C above and the rates of charge of each Lender for the purpose of E above shall be determined by the Administrative Agent based upon the information supplied to it pursuant to paragraphs 7 and 8 above and on the assumption that, unless a Lender notifies the Administrative Agent to the contrary, each Lender’s obligations in relation to cash ratio deposits and Special Deposits are the same as those of a typical bank from its jurisdiction of incorporation with a Lending Office in the same jurisdiction as its Lending Office.
10.	The Administrative Agent shall have no liability to any Person if such determination results in an Additional Cost Rate which over- or under-compensates any Lender and shall be entitled to assume that the information provided by any Lender pursuant to paragraphs 3, 7 and 8 above is true and correct in all respects.
11.	The Administrative Agent shall distribute the additional amounts received as a result of the Mandatory Cost Rate to the Lenders on the basis of the Additional Cost Rate for each Lender based on the information provided by each Lender pursuant to paragraphs 3, 7 and 8 above.
12.	Any determination by the Administrative Agent pursuant to this Schedule in relation to a formula, the Mandatory Cost Rate, an Additional Cost Rate or any amount payable to a Lender shall, in the absence of manifest error, be conclusive and binding on all parties hereto.
13.	The Administrative Agent may from time to time, after consultation with the Borrower and the Lenders, determine and notify to all parties any amendments which are required to be made to this Schedule in order to comply with any change in law, regulation or any requirements from time to time imposed by the Bank of England, the Financial Services Authority or the European Central Bank (or, in any case, any other authority which replaces all or any of their respective functions) and any such determination shall, in the absence of manifest error, be conclusive and binding on all parties hereto.

W I T N E S S E T H

     WHEREAS, Weatherford Delaware, certain subsidiaries of Weatherford Delaware and GPI previously entered into those certain agreements entitled “Distribution Agreement” by and between Weatherford International, Inc. and Grant Prideco, Inc. dated March 22, 2000 (the “Distribution Agreement”) (attached hereto) and “Employee Benefits Agreement” dated April 10, 2000 (the “Employee Benefits Agreement”) (attached hereto);

     WHEREAS, pursuant to the Distribution Agreement, Weatherford Delaware distributed to its stockholders all of the outstanding shares of the common stock of GPI, $.01 par value (the “Distribution”);

     WHEREAS, Weatherford Delaware and certain of its affiliates maintain (i) the Weatherford International, Inc. Executive Deferred Compensation Stock Ownership Plan (the “Weatherford Deferred Compensation Plan”), (ii) the Weatherford International, Inc. Foreign Executive Deferred Compensation Plan (the “Weatherford Foreign Deferred Compensation Plan”) and (iii) the Weatherford International, Inc. Executive Deferred Compensation Plan for Non-Employee Directors (the “Weatherford Directors’ Deferred Compensation Plan”) (collectively, the “Weatherford Plans”);

     WHEREAS, a multiple grantor trust entitled “Energy Ventures, Inc. Executive Deferred Compensation Stock Ownership Trust” (the “Trust”) was previously established to assist employers in meeting their obligations under the Weatherford Deferred Compensation Plan;

     WHEREAS, as of the record date for the Distribution the Trust held shares of Weatherford Delaware common stock for the Weatherford Deferred Compensation Plan and Weatherford Delaware held shares of Weatherford Delaware common stock for the Weatherford Foreign Deferred Compensation Plan and the Weatherford Directors’ Deferred Compensation Plan;

     WHEREAS, both Weatherford Delaware and the trustee of the Trust waived their rights to receive a distribution of GPI common stock in connection with the Distribution;

     WHEREAS, in accordance with the Employee Benefits Agreement, upon the Distribution, the account of each participant in each of the Weatherford Plans was deemed to be credited with one unit equal to one share of GPI common stock for every unit equal to one share of Weatherford Delaware common stock that was credited to such participant’s Weatherford Plan account as of the record date for the Distribution;

-1-

     WHEREAS, pursuant to the Distribution Agreement by and between Weatherford Delaware and GPI, GPI granted Weatherford Delaware employees and directors options to purchase shares of GPI common stock, $.01 par value, and a warrant to purchase shares of GPI common stock;

     WHEREAS, in the Distribution Agreement, GPI agreed to issue shares of its common stock upon the exercise of any option or warrant granted by GPI pursuant to the Distribution Agreement;

     WHEREAS, in the Employee Benefits Agreement, GPI agreed to issue shares of its common stock directly to participants in the Weatherford Plans as distributions became due under such plans with respect to units equal to shares of GPI common stock credited to participants’ accounts under such plans in accordance with the Employee Benefits Agreement;

     WHEREAS, pursuant to that certain instrument entitled “Assumption and General Amendment of Directors’ Stock Option and Benefit Programs and General Amendment of Employee Stock Option and Benefit Programs of Weatherford International, Inc.” dated June 26, 2002, by and between Weatherford Bermuda and Weatherford Delaware, Weatherford Bermuda assumed certain obligations of Weatherford Delaware with respect to the Weatherford Plans and certain Weatherford Delaware stock option plans;

     WHEREAS, NOV, NOV Sub, Inc. and GPI have entered into an Agreement and Plan of Merger by and among National Oilwell Varco, Inc., NOV Sub, Inc. and Grant Prideco, Inc. dated as of December 16, 2007 (the “Merger Agreement”);

     WHEREAS, as of the Effective Time, pursuant to this Agreement the account of each Weatherford Plan participant that is credited with units representing shares of GPI common stock shall be deemed to be credited with a certain number of units representing NOV common stock calculated as specified herein; and

     WHEREAS, the parties hereto desire to clarify the manner in which GPI’s obligation under the Employee Benefits Agreement to issue shares of GPI common stock to participants in the Weatherford Plans as distributions become due under such plans with respect to units equal to shares of GPI common stock credited to participants’ accounts under such plans will be implemented following the conversion of GPI common stock into NOV common stock in accordance with the Merger Agreement;

     NOW, THEREFORE, in consideration of the promises contained herein, and other valuable consideration, the receipt and sufficiency of which are hereby acknowledged by the parties, effective as of the Effective Time, Weatherford Bermuda, Weatherford Delaware, on behalf of itself and its subsidiaries, GPI and NOV agree as follows:

     (1) NOV hereby assumes GPI’s obligation under the Employee Benefits Agreement to issue shares of GPI common stock (which after the Effective Time will be converted into shares of NOV common stock, as adjusted herein) to participants in the Weatherford Plans as distributions become due under such plans. At the Effective Time, the units representing GPI common stock deemed credited under the Weatherford Plans determined in accordance with the Employee Benefits Agreement shall be converted into a certain number of units representing

-2-

NOV common stock. The number of such units representing GPI common stock credited to a Weatherford Plan participant’s account shall be converted into such number of units representing NOV common stock as is equal to the number of units representing GPI common stock credited to the participant’s account multiplied by the Conversion Ratio. For purposes of this Agreement, the term “Conversion Ratio,” which it is agreed shall be calculated to four decimal places, means the sum of (A) the Exchange Ratio and (B) the quotient of (i) the Cash Consideration per share of GPI common stock divided by (ii) the average of the last reported sales price of NOV common stock, as reported on the NYSE Composite Transactions Tape (as reported in The Wall Street Journal or, if not reported therein, in another authoritative source mutually selected by Weatherford Delaware and NOV), on each of the ten consecutive trading days immediately preceding the date of the Effective Time.
