THIS AMENDED AND RESTATED CREDIT AGREEMENT dated as of June 14, 2006 (this “Agreement”), is among ▇▇▇▇▇ CORPORATION, a Nevada corporation (the “Borrower”), the banks named on the signature pages hereto (together with their respective successors and assigns in such capacity, the “Banks”), JPMORGAN CHASE BANK, N.A., as Funds Administrator (the “Funds Administrator”) and as Administrative Agent (the “Agent”), ▇▇▇▇▇ FARGO BANK, N.A. and BANK OF AMERICA, N.A., each as a Syndication Agent and THE BANK OF TOKYO-MITSUBISHI UFJ, LTD. and DNB NOR BANK ASA, each as a Documentation Agent. Unless otherwise defined herein, all capitalized terms used herein and defined in Article I are used herein as so defined.

PRELIMINARY STATEMENT

Pursuant to that certain Credit Agreement dated as of September 19, 1997 (the “Existing Credit Agreement”), among the Borrower, the banks named therein, the Agent as the Funds Administrator and the Agent, the parties named therein as Banks made a revolving credit facility available to the Borrower upon the terms and conditions set forth therein. Said Existing Credit Agreement was amended by that certain First Amendment to Credit Agreement dated as of January 30, 1998, that certain Second Amendment to Credit Agreement dated November 30, 1998, that certain Third Amendment to Credit Agreement dated November 5, 2001, that certain Fourth Amendment to Credit Agreement dated January 31, 2003 and that certain Fifth Amendment to Credit Agreement dated as of December 9, 2003, all of said Amendments among the Borrower, the Banks named therein, the Agent, the Funds Administrator and the other parties named therein as syndication agent or documentation agent (said parties, in such capacities, together with the Agent, the “Agents”).

The Borrower now requests that the Banks amend and restate the Existing Credit Agreement and provide the Borrower with a credit facility pursuant to which the Banks will commit to make Revolving Loans in a principal amount of up to $250,000,000 outstanding at any time. The proceeds of the Revolving Loans shall be used to refinance indebtedness, to finance working capital needs of the Borrower and its Subsidiaries and for their general corporate purposes, including permitted acquisitions.

In connection therewith, the Agent has agreed to serve in such capacity for the Banks and the Agent and the Banks are agreeable to the Borrower’s request, subject to the terms of this Agreement.

Accordingly, in consideration of the foregoing and the mutual covenants set forth herein, the parties hereto agree as follows:

ARTICLE I.

ARTICLE II.

COMMITMENTS AND TERMS OF CREDIT

Section 2.01 Commitments; Loans and Borrowings. (a) Each Bank severally agrees, on the terms and conditions hereinafter set forth, to make Revolving Loans to the Borrower from time to time on any Business Day during the period from the Effective Date up to, but excluding, the Termination Date in an aggregate principal amount that will not result in such Bank’s Revolving Credit Exposure exceeding at any time such Bank’s Commitment as set forth in Schedule 2.01. Subject to the terms and conditions of this Agreement, the Borrower may borrow, repay pursuant to Section 2.06 or prepay pursuant to Section 2.08 and reborrow under this Section 2.01(a) the Revolving Loans.

(b) Each Revolving Loan shall be made as part of a Borrowing consisting of Revolving Loans made by the Banks ratably in accordance with their respective Commitments. The failure of any Bank to make any Loan required to be made by it shall not relieve any other Bank of its obligations hereunder; provided that the Commitments of the Banks are several and no Bank shall be responsible for any other Bank’s failure to make Loans as required.

(c) Each Borrowing of a Revolving Loan shall be comprised entirely of Prime Rate Loans or Fixed Rate Loans as the Borrower may request in accordance herewith. Prime Rate Borrowing shall consist of Prime Rate Loans made on the same day by the Banks ratably according to their respective Commitment Percentages, and Prime Rate Borrowings may be in any amount. Each Fixed Rate Borrowing shall be in an aggregate amount not less than $1,000,000 or an integral multiple of $100,000 in excess thereof, and shall consist of Fixed Rate Loans of the same Type made on the same day by the Banks ratably according to their respective Commitment Percentages. Each Swingline Loan shall be in an amount that is an integral multiple of $1,000 and not less than $100,000 and shall accrue interest at a rate equal to the Federal Funds Rate plus the Applicable Margin for Eurodollar Rate Loans. Borrowings of more than one Type may be outstanding at the same time, but the Borrower shall not be entitled to request any Borrowing or to Convert Loans comprising any Borrowing into Revolving Loans of another Type, if after giving effect to such Borrowing or Conversion, as the case may be, any Bank would have outstanding at any one time more than six (6) different Types of Loans.

-2-

(d) Notwithstanding any other term or provision hereof no Loan shall be made if after giving effect thereto the aggregate principal amount of Loans outstanding would exceed the Total Commitment.

Section 2.02 Revolving Borrowing Procedures; Conversions. ii) Each Borrowing of a Revolving Loan shall be made upon the written, telecopied or facsimile transmitted request of the Borrower, given to the Funds Administrator not later than 11:00 a.m. (Houston time) on (i) the third Business Day prior to the proposed Borrowing Date in the case of a Eurodollar Rate Borrowing, (ii) the second Business Day prior to the proposed Borrowing Date in the case of an Adjusted CD Rate Borrowing or (iii) the Business Day immediately preceding the proposed Borrowing Date in the case of a Prime Rate Borrowing, and upon receipt the Funds Administrator shall give each other member of the Bank Group prompt notice of such request by telecopier, telex or cable. Each request for a Borrowing (a “Borrowing Request”) made by the Borrower shall be in substantially the form of Exhibit 2.02(a), specifying therein (A) the Borrowing Date for such Borrowing, (B) the Type of Loans comprising such Borrowing, (C) the aggregate amount of such Borrowing, and (D) in the case of a Fixed Rate Borrowing, the Interest Period for the Loans comprising such Borrowing. Each Bank shall, before 11:30 a.m. (Houston time) on the date of such Borrowing, make available for the account of its Applicable Lending Office to the Funds Administrator at its address referred to in Section 9.03, in same day funds, such Bank’s ratable portion of such Borrowing. After the Funds Administrator’s receipt of such funds and upon fulfillment of the applicable conditions set forth in Article III, the Funds Administrator will make such funds available to the Borrower at the Funds Administrator’s aforesaid address. Each Borrowing Request shall be irrevocable and binding on the Borrower.

(b) Unless the Funds Administrator shall have received notice from a Bank prior to any Borrowing Date that such Bank will not make available to the Funds Administrator such Bank’s ratable portion of such Borrowing, the Funds Administrator may assume that such Bank has made such portion available to the Funds Administrator on such Borrowing Date in accordance with Section 2.02(a) and the Funds Administrator may, in reliance upon such assumption, make available to the Borrower on such Borrowing Date a corresponding amount. If and to the extent that such Bank shall not have so made such ratable portion available to the Funds Administrator, such Bank and the Borrower severally agree to repay to the Funds Administrator forthwith on demand such corresponding amount, together with interest thereon for each day from the date such amount is made available to the Borrower until the date such amount is repaid to the Funds Administrator at (i) in the case of the Borrower, the interest rate applicable at the time to the Revolving Loans comprising such Borrowing and (ii) in the case of such Bank, the Federal Funds Rate. If such Bank shall repay to the Funds Administrator such corresponding amount, such amount so repaid shall constitute such Bank’s Loan as part of such Borrowing for purposes of this Agreement.

-3-

(c) The Borrower may, subject to the terms of this Agreement, on any Business Day, upon written, telecopied or facsimile transmitted notice to the Funds Administrator, given not later than 11:00 a.m. (Houston time) on (i) the third Business Day prior to the proposed Conversion Date in the case of a Conversion of Loans into Eurodollar Rate Loans, (ii) the second Business Day prior to the proposed Conversion Date in the case of a Conversion of Loans into Adjusted CD Rate Loans or (iii) the Business Day immediately preceding the proposed Conversion Date in the case of a Conversion of Loans into Prime Rate Loans, Convert all Loans comprising one or more Borrowings into Loans of another Type comprising a single Borrowing, and the Funds Administrator shall promptly transmit the contents of such notice to each other member of the Bank Group by telecopier, telex or cable. Each notice of a Conversion (a “Conversion Notice”) given by the Borrower shall be in substantially the form of Exhibit 2.02(c), specifying therein (A) the Conversion Date for such Conversion, (B) the Loans to be Converted, (C) the Type of Loans to which such Loans are to be Converted and (D) in the case of a Conversion into Fixed Rate Loans, the Interest Period for such Converted Loans. Notwithstanding any other term or provision hereof, after giving effect to any such Conversion, the size of all Borrowings outstanding hereunder and the number of different Types of Loans outstanding hereunder shall conform to the requirements of Section 2.01. In the event of any Conversion of Fixed Rate Loans on any day other than the last day of the Interest Period applicable thereto, the Borrower shall be obligated to reimburse the Banks in respect thereof pursuant to Section 2.12. If the Borrower shall fail to give a timely Conversion Notice conforming to the requirements of this Agreement with respect to any Fixed Rate Loans prior to the expiration of the Interest Period applicable thereto, such Fixed Rate Loans shall, automatically on the last day of such Interest Period, be Converted into Prime Rate Loans.

Section 2.03 Swingline Loans. iii) Subject to the terms and conditions set forth herein, the Swingline Bank agrees to make Swingline Loans to the Borrower on any Business Day during the period from the Effective Date up to, but excluding, the Termination Date, in an aggregate principal amount at any time outstanding that will not result in (i) the aggregate principal amount of outstanding Swingline Loans exceeding $25,000,000 or (ii) the sum of the total Revolving Credit Exposure exceeding the Total Commitment; provided that the Swingline Bank shall not be required to make a Swingline Loan to refinance an outstanding Swingline Loan. Within the foregoing limits and subject to the terms and conditions set forth herein, the Borrower may borrow, prepay and reborrow Swingline Loans.

(b) To request a Swingline Loan, the Borrower shall notify the Funds Administrator of such request by telephone (confirmed by telecopy), not later than 2:00 p.m. (Houston time), on the day of a proposed Swingline Loan. Each such notice shall be irrevocable and shall specify the requested date (which shall be a Business Day) and amount of the requested Swingline Loan. The Funds Administrator will promptly advise the Swingline Bank of any such notice received from the Borrower. The Swingline Bank shall make each Swingline Loan available to the Borrower by means of a credit to the general deposit account of the Borrower with the Swingline Bank (or, in the case of a Swingline Loan made to finance the reimbursement of a drawing under a Letter of Credit as provided in Section 2.16(b)(iv), by remittance to the Issuing Bank) by 2:00 p.m. (Houston time) on the requested date of such Swingline Loan.

-4-

(c) The Swingline Bank may by written notice given to the Administrative Agent not later than 9:00 a.m. (Houston time) on any Business Day require the Bank Group to acquire participations on such Business Day in all or a portion of the Swingline Loans outstanding. Such notice shall specify the aggregate amount of Swingline Loans in which Bank Group will participate. Promptly upon receipt of such notice, the Funds Administrator will give notice thereof to each Bank, specifying in such notice such Bank's Commitment Percentage of such Swingline Loan or Loans. Each Bank hereby absolutely and unconditionally agrees, upon receipt of notice as provided above, to pay to the Funds Administrator, for the account of the Swingline Bank, such Bank's Commitment Percentage of such Swingline Loan or Loans. Each Bank acknowledges and agrees that its obligation to acquire participations in Swingline Loans pursuant to this paragraph is absolute and unconditional and shall not be affected by any circumstance whatsoever, including the occurrence and continuance of a Default or reduction or termination of the Commitments, and that each such payment shall be made without any offset, abatement, withholding or reduction whatsoever. Each Bank shall comply with its obligation under this paragraph by wire transfer of immediately available funds, in the same manner as provided in Section 2.02 with respect to Loans made by such Bank (and Section 2.02 shall apply, mutatis mutandis, to the payment obligations of the Bank Group), and the Funds Administrator shall promptly pay to the Swingline Bank the amounts so received by it from the Bank Group. The Funds Administrator shall notify the Borrower of any participations in any Swingline Loan acquired pursuant to this paragraph, and thereafter payments in respect of such Swingline Loan shall be made to the Funds Administrator and not to the Swingline Bank. Any amounts received by the Swingline Bank from the Borrower (or other party on behalf of the Borrower) in respect of a Swingline Loan after receipt by the Swingline Bank of the proceeds of a sale of participations therein shall be promptly remitted to the Funds Administrator; any such amounts received by the Funds Administrator shall be promptly remitted by the Funds Administrator to the Bank Group that shall have made their payments pursuant to this paragraph and to the Swingline Bank, as their interests may appear; provided that any such payment so remitted shall be repaid to the Swingline Bank or to the Funds Administrator, as applicable, if and to the extent such payment is required to be refunded to the Borrower for any reason. The purchase of participations in a Swingline Loan pursuant to this paragraph shall not relieve the Borrower of any default in the payment thereof.

Section 2.04 The Notes. The Loans made by each Bank shall be evidenced by a single Note issued to such Bank by the Borrower (a) dated the date of this Agreement (or such other date as may be specified in Section 9.02), (b) payable to the order of such Bank in a principal amount equal to such Bank’s Commitment and (c) otherwise duly completed, substantially in the form of Exhibit 2.04. Each Loan made by a Bank to the Borrower and all payments made on account of the principal amount thereof shall be entered by such Bank in its records or on the schedule (or a continuation thereof) attached to the Note of such Bank, provided, however, that prior to any transfer of any such Note, such Bank shall endorse the amount and maturity of any outstanding Loans on the schedule (or a continuation thereof) attached to such Note.

Section 2.05 Reduction of the Commitments. The Borrower shall have the right, upon at least three Business Days’ notice to the Funds Administrator to terminate in whole or reduce ratably in part the unused portions of the respective Commitments of the Banks, provided, that each partial reduction shall be in the aggregate amount of $1,000,000 or an integral multiple of $1,000,000 in excess thereof.

-5-

Section 2.06 Repayment of Loans. The Borrower hereby unconditionally promises to pay (i) to the Funds Administrator for the account of each Bank the then unpaid principal amount of each Revolving Loan on the Termination Date, together with any unpaid interest accrued thereon and (ii) to the Swingline Bank the then unpaid principal amount of each Swingline Loan on the earlier of the Termination Date and the first date after such Swingline Loan is made that is the last day of the calendar month and is at least two (2) Business Days after such Swingline Loan is made; provided that on each date that a Borrowing of a Revolving Loan is made, the Borrower shall repay all Swingline Loans then outstanding.

Section 2.07 Interest Accrual, Payments, Etc. (a) Subject to the provisions of Section 9.13, the Borrower shall pay interest on the unpaid principal amount of each Loan made by each Bank from the date of such Loan until such principal amount shall be paid in full, on the dates and at the rates per annum specified as follows:

(i) if such Loan is a Prime Rate Loan, a rate per annum equal to the lesser of (A) the Highest Lawful Rate and (B) the Prime Rate in effect from time to time plus or minus, as applicable, the Applicable Margin in effect from time to time, and unpaid accrued interest on such Loans shall be payable on each Quarterly Payment Date and on the date such Prime Rate Loan shall be paid in full;

(ii) if such Loan is an Adjusted CD Rate Loan, a rate per annum equal at all times during the Interest Period for such Loan to the lesser of (A) the Highest Lawful Rate and (B) the sum of the Adjusted CD Rate for such Interest Period plus the Applicable Margin in effect as of the first day of such Interest Period, and unpaid accrued interest on such Loans shall be payable on each Quarterly Payment Date and on the last day of such Interest Period;

(iii) if such Loan is a Eurodollar Rate Loan, a rate per annum equal at all times during the Interest Period for such Loan to the lesser of (A) the Highest Lawful Rate and (B) the sum of the Eurodollar Rate for such Interest Period plus the Applicable Margin in effect as of the first day of such Interest Period, and unpaid accrued interest on such Loans shall be payable on each Quarterly Payment Date and on the last day of such Interest Period; or

(iv) if such Loan is a Swingline Loan, a rate per annum equal to the Federal Funds Rate plus the Applicable Margin for Eurodollar Rate Loans.

Any amount of principal or, to the extent permitted by applicable law, interest which is not paid when due (whether at stated maturity, by acceleration or otherwise) shall bear interest from the date on which such amount is due until such amount is paid in full, at a rate per annum (the “Default Rate”) equal at all times to the lesser of (A) the Highest Lawful Rate and (B) the Prime Rate in effect from time to time during the applicable period plus or minus, as applicable, the Applicable Margin in effect from time to time during such period plus two percent (2%), payable on demand.

(b) The Borrower shall pay to each Bank additional interest on the unpaid principal amount of each Eurodollar Rate Loan of such Bank, from the date of such Loan until such principal amount is paid in full, at an interest rate per annum equal at all times to the remainder obtained by subtracting (i) the Eurodollar Rate for the Interest Period for such Loan from (ii) the rate obtained by dividing such Eurodollar Rate by a percentage equal to 100% minus the Eurodollar Rate Reserve Percentage of such Bank for such Interest Period, payable on each date on which interest is payable on such Loan. Such additional interest shall be calculated by such Bank and notified to the Borrower (together with a copy of such Bank’s calculations) through the Funds Administrator.

-6-

(c) (i) The Agent shall give prompt notice to the Borrower and each other member of the Bank Group of the applicable interest rate determined by the Agent hereunder for each Borrowing. Each determination by the Agent (or, in the case of Section 2.07(b), by a Bank) of an interest rate hereunder shall be conclusive and binding for all purposes, absent manifest error.

(ii) If one or more Banks holding aggregate Commitment Percentages of at least fifty percent (50%) shall, at least one Business Day before the date of any requested Eurodollar Rate Borrowing, notify the Agent and the Funds Administrator that the Eurodollar Rate applicable to such Borrowing will not adequately reflect the cost to such Banks of making, funding or maintaining their respective Eurodollar Rate Loans for such Borrowing, the right of the Borrower to select Eurodollar Rate Loans for such Borrowing or any subsequent Borrowing shall be suspended until the Agent shall notify the Borrower and each other member of the Bank Group that the circumstances causing such suspension no longer exist, and each Loan comprising such Borrowing shall be made as, or Converted into, as applicable, a Prime Rate Loan.

(iii) If the Agent is unable to determine the Adjusted CD Rate in accordance with the definition thereof for any Adjusted CD Rate Borrowing or the Eurodollar Rate in accordance with the definition thereof for any Eurodollar Rate Borrowing, (A) the Agent shall forthwith notify the Borrower and each other member of the Bank Group that the interest rate cannot be determined for such Adjusted CD Rate Borrowing or Eurodollar Rate Borrowing, as the case may be, (B) each Adjusted CD Rate Borrowing or Eurodollar Rate Borrowing, as the case may be, previously requested but not yet funded or Converted, as applicable, will automatically be made as or Converted into, as applicable, a Prime Rate Borrowing, and (C) the obligation of the Banks to make Adjusted CD Rate Loans or Eurodollar Rate Loans, as the case may be, shall be suspended until the Agent shall notify the Borrower and each other member of the Bank Group that the circumstances causing such suspension no longer exist.

(d) As used in this Agreement and the other Loan Documents, “Applicable Margin” means, as to Loans consisting of a single Borrowing, a rate per annum determined pursuant to the table set forth below by reference to the Borrower’s S&P Rating, ▇▇▇▇▇’▇ Rating or Fitch Rating (individually, a “Rating” and collectively, the “Ratings”) and the Type of Loans comprising such Borrowing, whereby (i) if either ▇▇▇▇▇’▇ or S&P shall not have in effect a Rating (other than by reason of the circumstances referred to in the last sentence of this Section 2.07(d)), then such rating agency shall be deemed to have established a rating in the lowest of the categories set forth in the table below; (ii) if the ▇▇▇▇▇’▇ Rating and the S&P Rating shall differ by one level, the higher Rating shall apply; (iii) if the ▇▇▇▇▇’▇ Rating and the S&P Rating differ by more than one level and the Fitch Rating is equal to the higher of the ▇▇▇▇▇’▇ Rating and the S&P Rating, the higher Rating shall apply; (iv) if the ▇▇▇▇▇’▇ Rating, the S&P Rating and the Fitch Rating each differ by one level, and the ▇▇▇▇▇’▇ Rating and the S&P Rating differ by more than one level, the rating which is the middle rating shall apply; (v) if the ▇▇▇▇▇’▇ Rating and the S&P Rating differ by more than one level, and the Fitch rating is equal to the lower of the ▇▇▇▇▇’▇ and S&P Rating, the rating which is one level above the two lower Ratings shall apply; (vi) if the ▇▇▇▇▇’▇ Rating and the S&P Rating differ by more than one level, and the Borrower does not have a Fitch rating, the rating which is one level below the higher of the ▇▇▇▇▇’▇ Rating or the S&P Rating Ratings shall apply; and (vii) if the ▇▇▇▇▇’▇ Rating and the S&P Rating are the same, that Rating shall apply. Each change in the Applicable Margin shall apply during the period commencing on the effective date of such change and ending on the date immediately preceding the effective date of the next such change. If the rating system of ▇▇▇▇▇’▇, S&P, or Fitch shall change, or if any such rating agency shall cease to be in the business of rating corporate debt obligations, the Borrower and the Banks shall negotiate in good faith to amend this definition to reflect such changed rating system or the unavailability of ratings from such rating agency and, pending the effectiveness of any such amendment, the Applicable Margin shall be determined by reference to the rating most recently in effect prior to such change or cessation.

Section 2.08 Prepayments. (a) The Borrower may, from time to time on any Business Day, upon at least one Business Day’s notice to the Funds Administrator stating the proposed date and aggregate principal amount thereof, and if such notice is given, the Borrower shall, prepay the outstanding principal amount of the Prime Rate Loans (including any Swingline Loan) comprising part of the same Borrowing in whole or ratably in part; provided, that any partial prepayment of such Prime Rate Loans shall be in an aggregate principal amount of not less than $100,000. The Borrower may from time to time upon at least three Business Days’ notice to the Funds Administrator stating the proposed date and the aggregate principal amount thereof, and if such notice is given, the Borrower shall, prepay the outstanding principal amount of the Fixed Rate Loans comprising part of the same Borrowing in whole or ratably in part; provided, that any partial prepayment of such Fixed Rate Loans shall be in an aggregate principal amount of not less than $2,000,000 or an integral multiple of $1,000,000 in excess thereof. Subject to the preceding two sentences, Borrower may apply any optional prepayment of the Loans to such portions of the Loans as the Borrower may elect.

(b) The Borrower shall from time to time prepay the Loans comprising part of the same Borrowing in such amounts as shall be necessary so that at all times the aggregate amount of Loans outstanding shall not be in excess of the Total Commitment. Any prepayment required by this Section 2.08(b) shall be due on the date such prepayment accrues pursuant to the preceding sentence.

-8-

(c) Each prepayment of Fixed Rate Loans shall be accompanied by a prepayment of accrued interest to the date of such prepayment on the principal amount prepaid. In the event of any prepayment of a Fixed Rate Loan, the Borrower shall be obligated to reimburse the Banks in respect thereof pursuant to Section 2.12. Unless otherwise specified by the Borrower, all mandatory prepayments of the Loans shall first be applied to Prime Rate Borrowings, and second to such Fixed Rate Borrowings as the Funds Administrator may select.

Section 2.09 Payments and Computations. (a) All payments of principal, interest, commitment fees and other amounts payable to the Banks under the Loan Documents shall be made in Dollars to the Funds Administrator at its address specified in Section 9.03 for the account of each of the Banks, in immediately available funds not later than 12:00 Noon (Houston time) on the date when due. Upon receipt of such payments, the Funds Administrator will promptly cause to be distributed like funds relating to the payment of principal or interest or commitment fees ratably (other than amounts payable pursuant to Section 2.07(b), Section 2.11, Section 2.12, Section 2.13 or Section 2.14) to the Banks for the account of their respective Applicable Lending Offices, and like funds relating to the payment of any other amount payable to any Bank to such Bank for the account of its Applicable Lending Office, in each case to be applied in accordance with the terms of this Agreement. In the event the Funds Administrator receives any such payment in immediately available funds not later than 12:00 Noon (Houston time) on any Business Day, but fails to distribute to any Bank entitled thereto like funds relating to such payment by the close of business on such Business Day, then the Funds Administrator shall pay such Bank interest thereon at the Federal Funds Rate for each day from the date such amount is received by the Funds Administrator until the date distributed to such Bank.

(b) Unless the Funds Administrator shall have received notice from the Borrower prior to the date on which any payment is due to the Banks under the Loan Documents that the Borrower will not make such payment in full, the Funds Administrator may assume that the Borrower has made such payment in full to the Funds Administrator on such date and the Funds Administrator may, in reliance upon such assumption, cause to be distributed to each Bank on such due date an amount equal to the amount then due such Bank. If and to the extent the Borrower shall not have made such payment in full to the Funds Administrator each Bank shall repay to the Funds Administrator forthwith on demand such amount distributed to such Bank, together with interest thereon for each day from the date such amount is distributed to such Bank until the date such Bank repays such amount to the Funds Administrator at the Federal Funds Rate.

(c) All payments by the Borrower of the fees payable to the Agent pursuant to the Fee Letter shall be made in Dollars directly to the Agent at its address specified in Section 9.03 in immediately available funds not later than 12:00 Noon (Houston time) on the date when due.

(d) All computations of interest based on the Prime Rate shall be made on the basis of a year of 365 or 366 days, as the case may be, and all computations of interest based on the Adjusted CD Rate, the Eurodollar Rate, the Federal Funds Rate, or Section 2.07(b), as well as commitment fees, shall be made on the basis of a year of 360 days (unless use of a 360 day year would cause the interest contracted for, charged or received hereunder to exceed the Highest Lawful Rate, in which case such computations shall be made on the basis of a year of 365 or 366 days, as the case may be), 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 commitment fees are payable.

-9-

(e) Whenever any payment under the Loan Documents 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 commitment fee, as the case may be; provided, however, if such extension would cause payment of interest on or principal of Eurodollar Rate Loans to be made in the next following calendar month, such payment shall be made on the next preceding Business Day.

(f) If any Bank shall obtain any payment (whether voluntary, involuntary, through the exercise of any right of setoff, or otherwise) on account of the Loans made by it (other than pursuant to Section 2.07(b), Section 2.11, Section 2.12, Section 2.13 or Section 2.14) in excess of its ratable share of payments on account of the Loans obtained by all the Banks, such Bank shall forthwith purchase from the other Banks such participations in the Loans made by such other Banks as shall be necessary to cause such purchasing Bank to share the excess payment ratably with each of them. The Borrower agrees that any Bank so purchasing a participation from another Bank pursuant to this Section 2.09(f) may, to the fullest extent permitted by law and this Agreement, exercise all its rights of payment (including the right of setoff) with respect to such participation as fully as if such Bank were the direct creditor of the Borrower in the amount of such participation.

Section 2.10 Fees. (a) Subject to the provisions of Section 9.13, the Borrower shall pay each Bank a commitment fee equal to the applicable percentage set forth in the pricing grid in Section 2.07(d) on the average unused portion of the Commitment of such Bank as in effect from time to time for the period from the date hereof to, but excluding, the Termination Date. Accrued commitment fees shall be due and payable in arrears on each Quarterly Payment Date in each year, on the date of any reduction or termination of the Commitment of such Bank and on the Termination Date, and shall be computed for the period commencing with the day to which such fee was last paid (or, in the case of the first commitment fee payment date, for the period commencing with and including the date hereof) to the date such fee is due and payable.

(b) Subject to the provisions of Section 9.13, the Borrower shall pay the Agent the arrangement and administrative fees specified in that certain letter agreement dated __________, 2006 between the Agent and the Borrower concerning the same (the “Fee Letter”).

(c) Subject to the provisions of Section 9.13, the Borrower shall pay to the Agent for the pro-rata accounts of the Banks, a utilization fee equal to the applicable percentage set forth in the grid contained in Section 2.07(d) on the daily average outstanding balance of the Loans during all times for which the principal balance of the Loans outstanding (including all outstanding, undrawn Letters of Credit) exceeds 33% of the Total Commitment.

Section 2.11 Setoff, Counterclaims and Taxes. (a) All payments of principal, interest, expenses, reimbursements, compensation, commitment fees, letter of credit fees, arrangement fees or administration fees and any other amount from time to time due under any Loan Document shall be made by the Borrower without setoff or counterclaim and shall be made 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 member of the Bank Group, taxes imposed on its income (or a taxable base in the nature of net income, or, in lieu of taxes so imposed or measured, on overall gross receipts and capital), and franchise taxes imposed on it, by the jurisdiction under the laws of which such member of the Bank Group is organized or any political subdivision thereof and, in the case of each Bank, taxes imposed on its income, and franchise taxes imposed on it, by the jurisdiction of such Bank’s Applicable Lending Office or any political subdivision thereof (all such non-excluded taxes, levies, imposts, deductions, charges, withholdings and liabilities being hereinafter referred to as “Taxes”). If the Borrower shall be required by law to deduct any Taxes from or in respect of any sum payable under any Loan Document to any member of the Bank Group, (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 member of the Bank Group receives an amount equal to the sum it would have received had no such deductions been made, (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 law; provided that the Borrower shall not be required to pay any increased amount on account of Taxes to the extent that any such Bank shall not have furnished the Borrower with such forms, or shall not have taken such other action, as reasonably may be available to it under applicable tax laws and any applicable tax treaty to obtain an exemption from, or reduction of, such Taxes.

(b) 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 under any Loan Document or from the execution, delivery or registration of, or otherwise with respect to, any Loan Document (hereinafter referred to as “Other Taxes”).

(c) The Borrower will indemnify each member of the Bank Group for the full amount of Taxes or Other Taxes (including, without limitation, any Taxes or Other Taxes imposed by any jurisdiction on amounts payable under this Section 2.11) paid by such member of the Bank Group (whether paid on its own behalf or on behalf of any other member of the Bank Group) and any liability (including penalties, interest and expenses) arising therefrom or with respect thereto, whether or not such Taxes or Other Taxes were correctly or legally asserted. This indemnification shall be made within 30 days from the date such member of the Bank Group makes written demand therefor.

(d) Within 30 days after the date of any payment of Taxes, the Borrower will furnish to the Agent, at its address referred to in Section 9.03, the original or a certified copy of a receipt evidencing payment thereof. If no Taxes are payable in respect of any payment made under any Loan Document, upon the request of the Agent, the Borrower will furnish to the Agent and the Funds Administrator, at its address referred to in Section 9.03, a certificate from each appropriate taxing authority, or an opinion of counsel acceptable to the Agent, in either case stating that such payment is exempt from or not subject to Taxes.

-11-

(e) Without prejudice to the survival of any other agreement of the Borrower hereunder, the agreements and obligations of the Borrower contained in this Section 2.11 shall survive the payment in full of the Loans and all other amounts owing under the other Loan Documents. The provisions of this Section 2.11 are in all respects subject to Section 9.13 hereof.

(f) Each Bank represents and warrants to the Agent, the Funds Administrator and the Borrower that such Bank is either (i) a corporation organized under the laws of the United States, a state thereof or the District of Columbia, or (ii) entitled to complete exemption from United States withholding tax imposed on or with respect to any payments, including fees, to be made to it pursuant to this Agreement and the other Loan Documents (x) under an applicable provision of a tax convention or treaty to which the United States is a party or (y) because it is acting through a branch, agency or office in the United States and any payment to be received by it hereunder is effectively connected with a trade or business in the United States. Upon becoming a party to this Agreement (whether by assignment or as an original signatory hereto), and in any event, from time to time upon the request of the Agent, the Funds Administrator or the Borrower, each Bank which is not a corporation organized under the laws of the United States or any state thereof or the District of Columbia shall deliver to the Agent, the Funds Administrator and the Borrower such forms, certificates or other instruments as may be required by the Agent and the Funds Administrator in order to establish that such Bank is entitled to complete exemption from United States withholding taxes imposed on or with respect to any payments, including fees, to be made to such Bank under this Agreement and the other Loan Documents. Each Bank also agrees to deliver to the Borrower, the Agent and the Funds Administrator such other supplemental forms as may at any time be required as a result of the passage of time or changes in applicable law or regulation in order to confirm or maintain in effect its entitlement to exemption from United States withholding tax on any payments hereunder; provided, that the circumstances of the Bank at the relevant time and applicable laws permit it to do so. If a Bank determines, as a result of any change in either (1) applicable law, regulation or treaty, or in any official application thereof or (2) its circumstances, that it is unable to submit any form or certificate that it is obligated to submit pursuant to this Section 2.11(f), or that it is required to withdraw or cancel any such form or certificate previously submitted, it shall promptly notify the Borrower, the Agent and the Funds Administrator of such fact. If a Bank is organized under the laws of a jurisdiction outside the United States, and the Borrower, the Funds Administrator and the Agent have not received forms, certificates or other instruments indicating to their satisfaction that all payments to be made to such Bank hereunder are not subject to United States withholding tax or the Agent otherwise has reason to believe that such Bank is subject to U.S. withholding tax, the Borrower shall withhold taxes from such payments at the applicable statutory rate. Each Bank shall indemnify and hold the Borrower, the Funds Administrator and the Agent harmless from any United States taxes, penalties, interest and other expenses, costs and losses incurred or payable by them as a result of either (A) such Bank’s failure to submit any form or certificate that it is required to provide pursuant to this Section 2.11(f) or (B) reliance by the Borrower, the Funds Administrator or the Agent on any such form or certificate which such Bank has provided to them pursuant to this Section 2.11(f).

-12-

(g) Any Bank claiming any additional amounts payable pursuant to this Section 2.11 shall use reasonable efforts (consistent with legal and regulatory restrictions) to file any certificate or document requested by the Borrower or to change the jurisdiction of its Applicable Lending Office if such a filing or change would avoid the need for or reduce the amount of any such additional amounts which may thereafter accrue and would not, in the sole determination of such Bank, be otherwise disadvantageous to such Bank.

Section 2.12 Funding Losses. The Borrower shall indemnify each member of the Bank Group against any loss or reasonable expense (including, but not limited to, any loss or reasonable expense sustained or incurred or to be sustained or incurred in liquidating or reemploying deposits from third parties acquired to effect or maintain a Loan or any part thereof as a Fixed Rate Loan) which such Person may sustain or incur as a consequence of (a) any failure by the Borrower to fulfill on the date of any Borrowing hereunder the applicable conditions set forth in Article III, (b) any failure by the Borrower to borrow hereunder or to Convert Loans hereunder after a Borrowing Request or Conversion Notice, respectively, has been given, (c) any payment, prepayment or Conversion of a Fixed Rate Loan required or permitted by any other provisions of this Agreement, including, without limitation, payments made due to the acceleration of the maturity of the Loans pursuant to Section 7.01, or otherwise made on a date other than the last day of the applicable Interest Period, (d) any default in the payment or prepayment of the principal amount of any Loan or any part thereof or interest accrued thereon, as and when due and payable (at the due date thereof, by notice of prepayment or otherwise) or (e) the occurrence of an Event of Default. Such loss or reasonable expense shall include, without limitation, an amount equal to the excess, if any, as determined by each Bank of (i) its cost of obtaining the funds for the Loan being paid, prepaid or Converted or not borrowed or Converted (based on the Fixed Rate applicable thereto) for the period from the date of such payment, prepayment or Conversion or failure to borrow or Convert to the last day of the Interest Period for such Loan (or, in the case of a failure to borrow or Convert, the Interest Period for the Loan which would have commenced on the date of such failure to borrow or Convert) over (ii) the amount of interest (as estimated by such Bank) that would be realized by such Bank in reemploying the funds so paid, prepaid or Converted or not borrowed or Converted for such period or Interest Period, as the case may be. A certificate of each member of the Bank Group setting forth any amount or amounts which such Person is entitled to receive pursuant to this Section 2.12 shall be delivered to the Borrower (with a copy to the Agent and the Funds Administrator) and shall be conclusive, if made in good faith, absent manifest error. The Borrower shall pay to the Funds Administrator for the account of each such Person the amount shown as due on any certificate within 30 days after its receipt of the same. Notwithstanding the foregoing, in no event shall any Bank be permitted to receive any compensation hereunder constituting interest in excess of the Highest Lawful Rate. Without prejudice to the survival of any other obligations of the Borrower hereunder, the obligations of the Borrower under this Section 2.12 shall survive the termination of this Agreement and/or the payment or assignment of any of the Notes.

Section 2.13 Change of Law. (a) If at any time any Bank determines in good faith (which determination shall be conclusive) that any change in any applicable law, rule or regulation or in the interpretation, application or administration thereof makes it unlawful, or any central bank or other Governmental Authority asserts that it is unlawful, for such Bank or its foreign branch or branches to fund or maintain any Eurodollar Rate Loan (any of the foregoing determinations being a “Eurodollar Event”), then, such Bank, at its option, may: (i) declare that Eurodollar Rate Loans will no longer be made or maintained by such Bank, whereupon the right of the Borrower to select Eurodollar Rate Loans for any Borrowing shall be suspended until such Bank shall notify the Funds Administrator and the Agent that the circumstances causing such Eurodollar Event no longer exist; (ii) with respect to any Eurodollar Rate Loans of such Bank then outstanding, require that all such Eurodollar Rate Loans be Converted to Prime Rate Loans, in which event all such Eurodollar Rate Loans shall automatically be Converted into Prime Rate Loans on the effective date of notice of such Eurodollar Event and all payments or prepayments of principal that would have otherwise been applied to repay such Converted Eurodollar Rate Loans shall instead be applied to repay the Prime Rate Loans resulting from such Conversion; and/or (iii) with respect to any Eurodollar Rate Loans requested of such Bank but not yet made as or Converted into such, require that such Eurodollar Rate Loans be made as or Converted into, as applicable, Prime Rate Loans.

-13-

(b) Upon the occurrence of any Eurodollar Event, and at any time thereafter so long as such Eurodollar Event shall continue, such Bank may exercise its aforesaid option by giving written notice thereof to the Funds Administrator, the Agent and the Borrower, such notice to be effective upon receipt thereof by the Borrower. Any Conversion of any Eurodollar Rate Loan which is required under this Section 2.13 shall be made, together with accrued and unpaid interest and all other amounts payable to such Bank under this Agreement with respect to such Converted Loan (including, without limitation, amounts payable pursuant to Section 2.12 hereof), on the date stated in the notice to the Borrower referred to above.

Section 2.14 Increased Costs. (a) If, due to either (i) the introduction of or any change in or in the interpretation of any law or regulation or (ii) the compliance with any guideline issued or request made after the Effective Date by any central bank or other Governmental Authority (whether or not having the force of law), there shall be any increase in the cost to any Bank of agreeing to make or making, funding or maintaining Adjusted CD Rate Loans or Eurodollar Rate Loans, then the Borrower shall from time to time, subject to the provisions of Section 9.13, pay to the Funds Administrator for the account of such Bank additional amounts sufficient to compensate such Bank for such increased cost upon demand by such Bank.

(b) If any Bank shall have determined in good faith that any law, rule, regulation or guideline adopted pursuant to or arising out of the July 1988 report of the Basel Committee on Banking Regulations and Supervisory Practices entitled “International Convergence of Capital Measurement and Capital Standards” and becoming applicable to such Bank after the Effective Date, or that the adoption after the Effective Date of any applicable law, rule, regulation or guideline regarding capital adequacy, or any change in any of the foregoing or in the interpretation or administration thereof by any central bank or other Governmental Authority charged with the interpretation or administration thereof, or compliance by such Bank (or any lending office of such Bank) with any request or directive regarding capital adequacy (whether or not having the force of law) issued after the Effective Date by any such Governmental Authority or comparable agency, affects or would affect the amount of capital required or expected to be maintained by such Bank or any corporation controlling such Bank and that the amount of such capital is increased by or based upon the existence of such Bank’s Commitment hereunder and other commitments of this type, then the Borrower shall from time to time, subject to the provisions of Section 9.13, pay to such Bank upon demand additional amounts sufficient to compensate such Bank or such corporation in light of such circumstances, to the extent that such Bank reasonably determines such increase in capital to be allocable to the existence of such Bank’s Commitment hereunder and similar amounts are being charged generally to other borrowers with similar commitments from such Bank.

-14-

(c) Each Bank will notify the Borrower of any event occurring after the date of this Agreement which will entitle such Bank to compensation pursuant to this Section 2.14 as promptly as practicable after such Bank obtains knowledge of the occurrence of such event. In no event will the Borrower be obligated to compensate any Bank pursuant to this Section 2.14 for any amounts described in paragraphs (a) or (b) above that accrued more than one hundred eighty (180) days prior to the date the notice described in the preceding sentence is given by the party requesting such compensation, but the foregoing shall in no way limit the right of such Bank to request compensation for amounts accrued during such one hundred eighty (180) day period or any future period. A certificate of such Bank setting forth in reasonable detail (i) such amount or amounts as shall be necessary to compensate such Bank (or participating banks or other entities pursuant to Section 9.02) as specified above and (ii) the calculation of such amount or amounts shall be delivered to the Borrower and shall be conclusive absent manifest error. The Borrower shall pay to such Bank the amount shown as due on any such certificate within thirty (30) days after its receipt of the same. The failure of any Bank to demand compensation for any increased costs or reduction in amounts received or receivable or reduction in return on capital shall not constitute a waiver of the right of such Bank or any other Bank, to demand compensation for any increased costs or reduction in amounts received or receivable or reduction in return on capital. The protection of this Section 2.14 shall be available to the Banks regardless of any possible contention of invalidity or inapplicability of law, regulation or condition which shall have been imposed.

Section 2.15 Substitution of Banks. If one or more Banks requests compensation pursuant to Section 2.14 or declares a Eurodollar Event pursuant to Section 2.13 or the Borrower is required to deduct United States withholding taxes pursuant to Section 2.11(f) from amounts payable to one or more Banks under the Loan Documents (any such request, declaration or withholding is herein called a “Substitution Event” and any such Bank is herein called an “Affected Bank”) the Borrower may give notice to such Affected Bank (with a copy to the Agent and the Funds Administrator) that it wishes to seek one or more Eligible Assignees (which may be one or more of the other Banks) to assume the Commitment of such Affected Bank and to purchase the Loans of such Affected Bank and the other interests of such Affected Bank in the Loan Documents (collectively, the “Affected Interests”). Each Affected Bank agrees to sell all of its Affected Interests pursuant to Section 9.02 to any such Eligible Assignee for an amount equal to the sum of the outstanding unpaid principal of and accrued interest on the Loans of such Affected Bank and all commitment fees and other fees and amounts due such Affected Bank under the Loan Documents, calculated, in each case, to the date such Affected Interests are purchased, whereupon such Affected Bank shall have no further Commitment or other obligation to the Borrower under the Loan Documents. Notwithstanding the foregoing, the Borrower may not replace any Affected Bank if (a) the Bank or Banks involved in such Substitution Event have aggregate Commitment Percentages in excess of thirty five percent (35%) or (b) the Borrower does not seek to replace each Bank involved in such Substitution Event.

Section 2.16 Letters of Credit.

(a) Subject to the terms and conditions of this Agreement, and on the condition that aggregate Letter of Credit Liabilities shall never exceed $25,000,000, Borrower shall have the right to, in addition to the Loans provided for in Section 2.01 hereof, utilize the Commitments from time to time during the term hereof by obtaining the issuance of letters of credit for the account of Borrower if Borrower shall so request in a form and with such accompanying documentation as Issuer may reasonably require not less than five (5) Business Days prior to the proposed date of issuance (such letters of credit, as any of them may be amended, supplemented, extended or confirmed from time to time, being herein collectively called the “Letters of Credit”). Upon the date of the issuance of a Letter of Credit, the Issuer shall be deemed, without further action by any party hereto, to have sold to each Bank, and each such Bank shall be deemed, without further action by any party hereto, to have purchased from the Issuer, a participation, to the extent of such Bank’s Commitment Percentage, in such Letter of Credit and the related Letter of Credit Liabilities, which participation shall terminate on the earlier of the expiration date of such Letter of Credit or the Termination Date.

(b) The following additional provisions shall apply to each Letter of Credit:

(i) Borrower shall give Agent and the Issuer notice requesting each issuance of a Letter of Credit hereunder as provided in Section 2.16(a) hereof and shall furnish such additional information regarding such transaction as Agent and the Issuer may reasonably request. Upon receipt of such notice, Issuer shall promptly notify each Bank of the contents thereof and of such Bank’s Commitment Percentage of the amount of such proposed Letter of Credit.

(ii) No Letter of Credit may be issued if after giving effect thereto the sum of (A) the aggregate outstanding principal amount of Loans plus (B) the aggregate Letter of Credit Liabilities with respect to Letters of Credit would exceed the Total Commitment. On each day during the period commencing with the issuance of any Letter of Credit and until such Letter of Credit shall have expired or been terminated, the Commitment of each Bank shall be deemed to be utilized for all purposes hereof in an amount equal to such Bank’s Commitment Percentage of the amount then available for drawings under such Letter of Credit (or any unreimbursed drawings under such Letter of Credit).

(iii) Upon receipt from the beneficiary of any Letter of Credit of any demand for payment thereunder, the Issuer shall promptly notify Borrower and each Bank as to the amount to be paid as a result of such demand and the payment date therefor. If at any time prior to the earlier of the expiration date of a Letter of Credit or the Termination Date, Issuer shall have made a payment to a beneficiary of a Letter of Credit in respect of a drawing under such Letter of Credit, each Bank will pay to Issuer promptly upon demand by Issuer at any time during the period commencing after such payment until reimbursement thereof in full by Borrower, an amount equal to such Bank’s Commitment Percentage of such payment, together with interest on such amount for each day from the date of demand for such payment (or, if such demand is made after 11:00 a.m. (Houston time) on such date, from the next succeeding Business Day) to the date of payment by such Bank of such amount at a rate of interest per annum equal to the Federal Funds Rate for such period.

-16-

(iv) Borrower shall be irrevocably and unconditionally obligated forthwith to reimburse Issuer, on the date on which Issuer notifies Borrower of the date and amount of any payment by Issuer of any drawing under a Letter of Credit, for the amount paid by Issuer upon such drawing, without presentment, demand, protest or other formalities of any kind, all of which are hereby waived. Such reimbursement may, subject to satisfaction of the conditions in Sections 3.01 and 3.02 hereof and to the limitations of the Total Commitment (after adjustment in the same to reflect the elimination of the corresponding Letter of Credit Liability), be made by a Borrowing of Loans. Issuer will pay to each Bank such Bank’s Commitment Percentage of all amounts received from Borrower for application in payment, in whole or in part, in respect of any Letter of Credit, but only to the extent such Bank has made payment to Issuer in respect of such Letter of Credit pursuant to clause (iii) above.

(v) Borrower will pay to Agent for the account of each Bank a letter of credit fee with respect to each Letter of Credit equal to the Eurodollar Rate Applicable Margin per annum, multiplied by the face amount of each Letter of Credit (and computed on the basis of the actual number of days elapsed in a year composed of 360 days), in each case for the period from and including the date of issuance of such Letter of Credit to and including the date of expiration or termination thereof, such fee to be due and payable quarterly in arrears based on the date of the issuance thereof. Agent will pay to each Bank, promptly after receiving any payment in respect of letter of credit fees referred to in this clause (v), an amount equal to the product of such Bank’s Commitment Percentage times the amount of such fees. In addition to and cumulative of the above described fees, Borrower shall pay to Issuer, quarterly in arrears, based on the date of the issuance of the applicable Letter of Credit, a fee in an amount equal to 0.125% per annum of the face amount of the applicable Letter of Credit and shall pay reasonable and customary fees imposed and expenses incurred by Issuer in connection with the issuance, administration, amendment, payment and negotiation of said Letter of Credit (such fees and expense reimbursements to be retained by Issuer for its own account).

(vi) The issuance by Issuer of each Letter of Credit shall, in addition to the conditions precedent set forth in Article III hereof, be subject to the conditions precedent (A) that such Letter of Credit shall be in such form and contain such terms as shall be reasonably satisfactory to Issuer and Agent, and (B) that Borrower shall have executed and delivered such applications and other instruments and agreements relating to such Letter of Credit as Issuer and Agent shall have reasonably requested and which are not inconsistent with the terms of this Agreement. In the event of a conflict between the terms of this Agreement and the terms of any application, the terms of this Agreement shall control.

(vii) Issuer will send to each Bank, immediately upon issuance of any Letter of Credit a true and correct copy of such Letter of Credit.

-17-

(viii) Any Letter of Credit issued under this Agreement shall provide for an expiry date which is not later than the earlier of five (5) days prior to the Termination Date or twelve (12) months from the issuance date, provided, Borrower may request, and Issuer agrees to issue, Letters of Credit with expiry dates beyond five (5) days prior to the Termination Date if at the time of issuance thereof Borrower pledges to the Agent cash collateral in an amount and on such terms and conditions as Agent and Issuer may request. Each Letter of Credit which is self-extending beyond its stated expiration date must be cancelable upon no more than thirty (30) days’ written notice given by the Issuer to the beneficiary of such Letter of Credit.

(ix) The issuance of a Letter of Credit shall constitute the making of a Loan except as otherwise expressly set forth herein, and each Letter of Credit and all related applications and other documents executed or delivered in connection with any Letter of Credit shall be considered Loan Documents.

Section 2.17 Increase of Commitments.

(a) If no Default, Event of Default or Material Adverse Effect shall have occurred and be continuing, the Borrower may at any time and from time to time request an increase of the aggregate Commitments by notice to the Agent in writing, in the amount of such proposed increase request, substantially in the form of Exhibit 2.17(a) (such notice, a “Commitment Increase Notice”); provided, however, that (i) each such increase shall be at least $5,000,000, (ii) the cumulative increase in Commitments pursuant to this Section 2.17 shall not exceed $75,000,000 without the approval of the Majority Banks, (iii) the Commitment of any Bank may not be increased without such Bank’s consent, and (iv) the aggregate amount of the Banks’ Commitments shall not exceed $325,000,000 without the approval of the Majority Banks. Any such Commitment Increase Notice must offer each Bank the opportunity to subscribe for its pro rata share of the increased Commitment. If any portion of the increased Commitment is not subscribed for by such Banks, the Borrower may, in its sole discretion, but with the consent of the Agent as to any Person that is not at such time a Bank (which consent shall not be unreasonably withheld or delayed), offer to any existing Bank or to one or more additional banks or financial institutions the opportunity to participate in all or a portion of such unsubscribed portion of the increased Commitments pursuant to paragraph (b) or (c) below, as applicable.

(b) Any additional bank or financial institution that the Borrower selects to offer participation in the increased Commitment shall become a party to this Agreement by executing and delivering to the Agent an agreement, substantially in the form of Exhibit 2.17(b) (a “New Bank Agreement”) setting forth its Commitment, whereupon such bank or financial institution (a “New Bank”) shall become a Bank for all purposes and to the same extent as if originally a party hereto and shall be bound by and entitled to the benefits of this Agreement, and the signature pages hereof shall be deemed to be amended to add the name of such New Bank and the definition of Commitment in Annex A of the Credit Agreement hereof shall be deemed amended to increase the aggregate Commitments of the Banks by the Commitment of such New Bank, provided that the Commitment of any New Bank shall be an amount not less than $5,000,000.

-18-

(c) Any Bank that accepts an offer to it by the Borrower to increase its Commitment pursuant to this Section 2.17 shall, in each case, execute a Commitment Increase Agreement with the Borrower and the Agent, whereupon such Bank shall be bound by and entitled to the benefits of this Agreement with respect to the full amount of its Commitment as so increased, and the definition of Commitment in Annex A hereof shall be deemed to be amended to reflect such increase.

(d) The effectiveness of any New Bank Agreement or Commitment Increase Agreement shall be contingent upon receipt by the Agent of such corporate resolutions of the Borrower and legal opinions of counsel to the Borrower as the Agent shall reasonably request with respect thereto, in each case in form and substance reasonably satisfactory to the Agent.

(e) If any bank or financial institution becomes a New Bank pursuant to Section 2.17(b) or any Bank’s Commitment is increased pursuant to Section 2.17(c), additional Loans made on or after the effectiveness thereof (the “Re-Allocation Date”) shall be made pro rata based on their respective Commitments in effect on or after such Re-Allocation Date (except to the extent that any such pro rata borrowings would result in any Bank making an aggregate principal amount of Loans in excess of its Commitment, in which case such excess amount will be allocated to, and made by, such New Bank and/or Banks with such increased Commitments to the extent of, and pro rata based on, their respective Commitments), and continuations of Loans outstanding on such Re-Allocation Date shall be effected by repayment of such Loans on the last day of the Interest Period applicable thereto and the making of new Loans of the same Type pro rata based on the respective Commitments in effect on and after such Re-Allocation Date.

(f) If on any Re-Allocation Date there is an unpaid principal amount of Fixed Rate Loans or Prime Rate Loans, (i) any such Prime Rate Loans shall be reallocated immediately among the Banks (including any New Banks and any Banks that have executed a Commitment Increase Agreement) so that all Borrowing and Loans that are outstanding are pro rated based on each Bank’s Commitment, after giving effect to the Re-Allocation Date, and (ii) any such Fixed Rate Loans shall remain outstanding with the respective holders thereof until the expiration of their respective Interest Periods (unless the Borrower elects to prepay any thereof in accordance with the applicable provisions of this Agreement), and interest on and repayments of all Loans will be paid thereon to the respective Banks holding same pro rata based on the respective principal amounts thereof outstanding.

Any member of the Bank Group exercising such right agrees to notify the Borrower promptly after any such setoff and application made by such Person; provided, that the failure to give such notice shall not affect the validity of such setoff and application. The rights of the Bank Group under this Section 7.02 are in addition to other rights and remedies (including, without limitation, other rights of setoff) which the Bank Group may have hereunder or under any applicable law.

Section 7.03 No Waiver; Remedies.

Agent may, but shall have no obligation to, invest any such Proceeds of Remedies in such manner as Agent, in the exercise of its sole discretion, deems appropriate. Such Proceeds of Remedies shall be applied to amounts owing in respect of any such Letters of Credit and/or the payment of Borrower’s or any Bank’s obligations under any such Letter of Credit when such Letter of Credit is drawn upon. Nothing in this Section 7.04 shall cause or permit an increase in the maximum amount permitted to be outstanding from time to time under this Agreement.

As to any matters not expressly provided for by this Agreement (including, without limitation, enforcement or collection of the Notes or of amounts owing under the other Loan Documents), the Agent and the Funds Administrator shall not be required to exercise any discretion or take any action, but such Person shall be required to act or to refrain from acting (and shall be fully protected in so acting or refraining from acting) upon the instructions of the Majority Banks, and such instructions shall be binding upon all Banks and any other holders of Notes; provided, however, that the Agent and the Funds Administrator shall not be required to take any action which exposes such Person to personal liability or which is contrary to the Loan Documents or applicable law. Each of the Agent and the Funds Administrator is hereby expressly authorized on behalf of the other members of the Bank Group, (a) to receive on behalf of each of the other members of the Bank Group any payment of principal of or interest on the Loans outstanding hereunder and all other amounts accrued hereunder paid to such Persons, and promptly to distribute to each other member of the Bank Group its proper share of all payments so received; (b) in the case of the Agent only, to give notice within a reasonable time on behalf of each other member of the Bank Group to the Borrower of any Default of which the Agent has actual knowledge as provided in Section 8.09; (c) to distribute to the other members of the Bank Group copies of all notices, agreements and other material as provided for in this Agreement as received by such Person; and (d) to distribute to the Borrower any and all requests, demands and approvals received by such Person from any other member of the Bank Group. Nothing herein contained shall be construed to constitute either the Agent or the Funds Administrator as a trustee for any holder of the Notes or of a participation therein, nor to impose on any such Person any duties or obligations other than those expressly provided for in the Loan Documents.

Section 8.02 Reliance, Etc. The Agent, the Funds Administrator and their respective directors, officers, agents or employees shall not be liable for any action taken or omitted to be taken by it or them under or in connection with this Agreement, except for such acts or omissions of such Person constituting gross negligence or willful misconduct on the part of such Person (IT BEING THE EXPRESS INTENTION OF THE PARTIES THAT THE AGENT, THE FUNDS ADMINISTRATOR AND THEIR RESPECTIVE DIRECTORS, OFFICERS, EMPLOYEES AND AGENTS SHALL HAVE NO LIABILITY FOR ACTIONS AND OMISSIONS HEREUNDER RESULTING THAT CONSTITUTE ORDINARY NEGLIGENCE, WHETHER SOLE OR CONTRIBUTORY) OR RESULT IN STRICT LIABILITY. Without limitation of the generality of the foregoing, each of the Agent and the Funds Administrator: (a) may treat the payee of any Note as the holder thereof until the Agent receives and accepts an Assignment and Acceptance entered into by the Bank which is the payee of such Note, as assignor, and an Eligible Assignee, as assignee, as provided in Section 9.02, and the Agent notifies such Person thereof; (b) may consult with legal counsel (including counsel for the Borrower), independent public accountants and other experts selected by it and shall not be liable for any action taken or omitted to be taken in good faith by it in accordance with the advice of such counsel, accountants or experts; (c) makes no warranty or representation to any Bank and shall not be responsible to any Bank for any statements, warranties or representations (whether written or oral) made in or in connection with this Agreement or the other Loan Documents; (d) shall not have any duty to ascertain or to inquire as to the performance or observance of any of the terms, covenants or conditions of this Agreement or the other Loan Documents on the part of the Borrower or any other Person or to inspect the property (including the books and records) of the Borrower or any other Person; (e) shall not be responsible to any Bank for the due execution, legality, validity, enforceability, genuineness, sufficiency or value of any Loan Document, any collateral provided for therein, or any other instrument or document furnished pursuant thereto; and (f) shall incur no liability under or in respect of this Agreement by acting upon any notice, consent, certificate or other instrument or writing (which may be by telecopier, telegram, cable or telex) believed by it to be genuine and signed or sent by the proper party or parties. The Agent, the Funds Administrator and their respective directors, officers, employees or agents shall not have any responsibility to the Borrower on account of the failure or delay in performance or breach by any Bank of any of its obligations hereunder or to any Bank on account of the failure of or delay in performance or breach by any other Bank or the Borrower of any of their respective obligations hereunder or in connection herewith.

Section 8.03 Chase and Affiliates. Without limiting the right of any other Bank to engage in any business transactions with the Borrower or any of its Affiliates, with respect to its Commitment, the Loans made by it, the Note issued to it, and its interest in the Loan Documents, Chase shall have the same rights and powers under this Agreement as any other Bank and may exercise the same as though it were not the Funds Administrator or the Agent; and the term “Bank” or “Banks” shall, unless otherwise expressly indicated, include Chase in its individual capacity. Chase, or any of its Affiliates, may be engaged in, or may hereafter engage in, one or more loan, letter of credit, leasing or other financing activities not the subject of the Loan Documents (such financing activities of Chase being, collectively, the “Other Financings”) with the Borrower or any of its Affiliates, or may act as trustee on behalf of, or depositary for, or otherwise engage in other business transactions with the Borrower or any of its Affiliates (all Other Financings and other such business transactions of Chase being, collectively, the “Other Activities”) with no responsibility to account therefor to the Banks. Without limiting the rights and remedies of the Banks specifically set forth in the Loan Documents, no other Bank shall have any interest in (a) any Other Activities, (b) any present or future guarantee by or for the account of the Borrower not contemplated or included in the Loan Documents, (c) any present or future offset exercised by the Agent or the Funds Administrator in respect of any such Other Activities, (d) any present or future property taken as security for any such Other Activities or (e) any property now or hereafter in the possession or control of the Agent or the Funds Administrator which may be or become security for the obligations of the Borrower under the Loan Documents by reason of the general description of indebtedness secured, or of property, contained in any other agreements, documents or instruments related to such Other Activities; provided, however, that if any payment in respect of such guarantees or such property or the proceeds thereof shall be applied to reduction of the obligations evidenced hereunder and by the Notes, then each Bank shall be entitled to share in such application according to its pro rata portion of such obligations.

-38-

Section 8.04 Bank Credit Decision. Each Bank acknowledges that it has, independently and without reliance upon any other member of the Bank Group and based on the financial statements referred to in Section 4.06 and such other documents and information as it has deemed appropriate, made its own credit analysis and decision to enter into this Agreement. Each Bank also acknowledges that it will, independently and without reliance upon any other member of the Bank Group 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 8.05 Indemnification. The Banks agree to indemnify each of the Agent and the Funds Administrator (to the extent not reimbursed by the Borrower), ratably according to their respective Commitment Percentages, from and against any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind or nature whatsoever which may be imposed on, incurred by, or asserted against the Agent or the Funds Administrator, as the case may be, in any way relating to or arising out of this Agreement or the other Loan Documents or any action taken or omitted by the Agent or the Funds Administrator under this Agreement or the other Loan Documents, provided, that no Bank shall be liable for any portion of such liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements resulting from such Person’s gross negligence or willful misconduct. IT IS THE EXPRESS INTENTION OF THE PARTIES HERETO THAT THE AGENT AND THE FUNDS ADMINISTRATOR SHALL BE INDEMNIFIED AND HELD HARMLESS AGAINST ANY AND ALL LIABILITIES, OBLIGATIONS, LOSSES, DAMAGES, PENALTIES, ACTIONS, JUDGMENTS, SUITS, COSTS, EXPENSES OR DISBURSEMENTS OF ANY KIND ARISING OUT OF OR RESULTING FROM THE ORDINARY NEGLIGENCE (WHETHER SOLE OR CONTRIBUTORY) OR STRICT LIABILITY OF SUCH PERSON. The Agent and the Funds Administrator shall not be required to do any act hereunder or under any other document or instrument delivered hereunder or in connection herewith or take any action toward the execution or enforcement of the agencies hereby created, or to prosecute or defend any suit in respect of this Agreement or the Loan Documents or any collateral security, unless indemnified to its satisfaction by the holders of the Notes against loss, cost, liability, and expense. If any indemnity furnished to the Agent or the Funds Administrator for any purpose is, in the opinion of such Person insufficient or becomes impaired, such Person may call for additional indemnity and not commence or cease to do the acts indemnified against until such additional indemnity is furnished. Without limitation of the foregoing, each Bank agrees to reimburse the Agent and the Funds Administrator promptly upon demand for its ratable share of any out-of-pocket expenses (including counsel fees) incurred by such Person in connection with the preparation, execution, delivery, administration, modification, amendment or enforcement (whether through negotiations, legal proceedings or otherwise) of, or legal advice in respect of rights or responsibilities under, this Agreement and the other Loan Documents, to the extent that the Agent and the Funds Administrator are not reimbursed for such expenses by the Borrower.

-39-

Section 8.06 Employees of the Agent, Etc. Each of the Agent and the Funds Administrator may execute any of their respective duties under this Agreement, the other Loan Documents and any instrument, agreement or document executed, issued or delivered pursuant hereto or thereto or in connection herewith or therewith, by or through employees, agents and attorneys-in-fact, and shall not be answerable for the default or misconduct of any such employee, agent or attorney-in-fact selected by it with reasonable care. Each of the Agent and the Funds Administrator may, and upon the written instruction of the Majority Banks shall, enforce on behalf of the Banks any claims which the Agent, the Funds Administrator and/or the Banks may have against any such employee, agent or attorney-in-fact, and any recovery therefrom shall be applied for the pro rata benefit of the Banks.

Section 8.07 Successor Agent. The Agent may resign at any time by giving written notice thereof to the other members of the Bank Group and the Borrower and may be removed at any time with or without cause by the Majority Banks. Upon any such resignation or removal, the Majority Banks shall have the right to appoint a successor Agent. If no successor Agent shall have been so appointed by the Majority Banks, and shall have accepted such appointment, within thirty (30) days after the retiring Agent’s giving of notice of resignation or the Majority Banks’ removal of the retiring Agent, then the retiring Agent may, on behalf of the Banks, appoint a successor Agent, which shall be a commercial bank organized under the laws of the United States of America or of any State thereof and having a combined capital and surplus of at least $500,000,000.

Upon such execution, delivery, acceptance and recording, from and after the effective date specified in each Assignment and Acceptance, (1) the assignee thereunder shall be a party hereto and, to the extent that rights and obligations under the Loan Documents have been assigned to it pursuant to such Assignment and Acceptance, have the rights and obligations of a Bank under the Loan Documents and (2) the assigning Bank thereunder shall, to the extent that rights and obligations under the Loan Documents have been assigned by it pursuant to such Assignment and Acceptance, relinquish its rights and be released from its obligations under the Loan Documents (and, in the case of an Assignment and Acceptance covering all or the remaining portion of an assigning Bank’s rights and obligations under this Agreement, such Bank shall cease to be a party hereto).

-42-

(ii) In the event any Bank desires to transfer all or any portion of its rights and obligations under the Loan Documents to any Person other than an Affiliate of such Bank, it shall give the Borrower and the Agent prior written notice of the identity of such transferee and the terms and conditions of such transfer (a “Transfer Notice”). So long as no Default has occurred and is continuing, the Borrower may, no later than ten (10) days following receipt of such Transfer Notice, designate an alternative transferee and such Bank shall thereupon be obligated to sell the interests specified in such Transfer Notice to such alternative transferee, subject to the following: (A) such transfer shall be made on the same terms and conditions outlined in such Transfer Notice, (B) such transfer shall otherwise comply with the terms and conditions of the Loan Documents (including Section 9.02(a)(i)), and (C) such alternative transferee must be an Eligible Assignee approved by the Agent. If the Borrower shall fail to designate an alternative transferee within such ten (10) day period, such Bank shall, subject to compliance with the other terms and provisions hereof, be free to consummate the transfer described in such Transfer Notice.

(b) By executing and delivering an Assignment and Acceptance, the assigning Bank 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 assigning Bank makes no representation or warranty and assumes no responsibility with respect to any statements, warranties or representations made in or in connection with the Loan Documents or the execution, legality, validity, enforceability, genuineness, sufficiency or value of this Agreement or any other instrument or document furnished pursuant hereto; (ii) such assigning Bank 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 and the other Loan Documents, together with copies of the financial statements referred to in Section 4.06 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 any member of the Bank Group (including such assigning Bank) and based on such documents and information as it shall deem appropriate at the time, continue to make its own credit decisions in taking or not taking action under this Agreement; (v) such assignee confirms that it is an Eligible Assignee; (vi) such assignee appoints and authorizes the Agent and the Funds Administrator to take such action on its behalf and to exercise such powers under this Agreement and the other Loan Documents as are delegated to such Person by the terms thereof, together with such powers as are reasonably incidental thereto; and (vii) such assignee agrees that it will perform in accordance with their terms all of the obligations which by the terms of this Agreement and the other Loan Documents are required to be performed by it as a Bank.

(c) The Agent shall maintain at its address referred to in Section 9.03 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 Banks and the Commitment of, and principal amount of the Loans owing to, each Bank 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 and each member of the Bank Group may treat each Person whose name is recorded in the Register as a Bank hereunder for all purposes of this Agreement. The Register shall be available for inspection by the Borrower or any member of the Bank Group at any reasonable time and from time to time upon reasonable prior notice.

-43-

(d) Upon its receipt of an Assignment and Acceptance executed by an assigning Bank and an assignee representing that it is an Eligible Assignee, together with any Note subject to such assignment, the Agent shall, if such Assignment and Acceptance has been completed and is in substantially the form of Exhibit 9.02 and satisfies all other requirements set forth in this Section 9.02, (i) accept such Assignment and Acceptance, (ii) record the information contained therein in the Register and (iii) give prompt notice thereof to the Borrower and the other members of the Bank Group. Within five (5) Business Days after its receipt of such notice, the Borrower, at its own expense, shall execute and deliver to the Agent, in exchange for the surrendered Notes, new Notes to the order of such Eligible Assignee in an amount corresponding to the Commitment assumed by such Eligible Assignee pursuant to such Assignment and Acceptance and, if the assigning Bank has retained a Commitment hereunder, new Notes to the order of the assigning Bank in an amount corresponding to the Commitment retained by it hereunder. Such new Notes shall be in an aggregate principal amount equal to the aggregate principal amount of such surrendered Notes, shall be dated the effective date of such Assignment and Acceptance and shall otherwise be in substantially the form prescribed by Section 2.04 hereto.

(e) Each Bank 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 and the other Loan Documents (including, without limitation, all or a portion of its Commitment and the Loans owing to it); provided, however, that (i) such Bank’s obligations under this Agreement (including, without limitation, its Commitment to the Borrower hereunder) and the other Loan Documents shall remain unchanged, (ii) such Bank shall remain solely responsible to the other parties hereto for the performance of such obligations, and the participating banks or other entities shall not be considered a “Bank” for purposes of the Loan Documents, (iii) the participating banks or other entities shall be entitled to the cost protection provisions contained in Section 2.11 through Section 2.14 and the rights of setoff contained in Section 7.02, in each case to the same extent that the Bank from which such participating bank or other entity acquired its participation would be entitled to the benefit of such cost protection provisions and rights of setoff and (iv) the Borrower and the other members of the Bank Group shall continue to deal solely and directly with such Bank in connection with such Bank’s rights and obligations under this Agreement and the other Loan Documents, and such Bank shall retain the sole right to enforce the obligations of the Borrower relating to the Loans and to approve any amendment, modification or waiver of any provision of this Agreement (other than amendments, modifications or waivers with respect to the amounts of any fees payable hereunder or the amount of principal of or the rate at which interest is payable on the Loans, or the dates fixed for payments of principal or interest on the Loans).

(f) Anything in this Section 9.02 to the contrary notwithstanding, any Bank may at any time, without the consent of the Borrower or the Agent, assign and pledge all or any portion of its Commitment and the Loans owing to it to any Federal Reserve Bank (and its transferees) as collateral security pursuant to Regulation A of the Federal Reserve Board and any Operating Circular issued by such Federal Reserve Bank. No such assignment shall release the assigning Bank from its obligations hereunder.

-44-

(g) Any Bank may, in connection with any assignment or participation or proposed assignment or participation pursuant to this Section 9.02, disclose to the assignee or participant or proposed assignee or participant, any information relating to the Borrower furnished to such Bank by or on behalf of the Borrower; provided that prior to any such disclosure, each such assignee or participant or proposed assignee or participant shall agree (subject to customary exceptions) to preserve the confidentiality of any confidential information relating to the Borrower received from such Bank.

if to any Bank, at its Domestic Lending Office, or as to each such party, at such other address as such party shall designate in a written Communication to each of the other parties hereto. All such Communications shall be effective, in the case of written or telegraphed Communications, when deposited in the mails or delivered to the telegraph company, respectively, and, in the case of a Communication by telecopy or facsimile transmission, when telecopied or transmitted against receipt of a confirmation, in each case addressed as aforesaid, except that Communications to any member of the Bank Group pursuant to Article II and Article VIII shall not be effective until received by such Persons.

The agreements of Borrower contained in this Section 9.04 shall survive the termination of the Commitments and the payment of all other amounts owing hereunder or under any of the other Loan Documents.

Section 9.05 Successors and Assigns. This Agreement shall be binding upon and inure to the benefit of the Borrower, the Agent, the Funds Administrator, the Banks and their respective successors and assigns, except that the Borrower may not assign or transfer its rights hereunder without the prior written consent of the Banks.

Section 9.06 Independence of Covenants. All covenants contained in the Loan Documents shall be given independent effect so that if a particular action or condition is not permitted by any of such covenants, the fact that such action or condition would be permitted by an exception to, or otherwise be within the limitations of, another covenant shall not avoid the occurrence of a Default or an Event of Default if such action is taken or condition exists.

Section 9.07 Survival of Representations and Warranties. All representations and warranties contained in this Agreement and the other Loan Documents or made in writing by the Borrower in connection herewith or therewith, shall survive the execution and delivery of this Agreement, the Notes and the other Loan Documents and the repayment of the Loans. Any investigation by any member of the Bank Group shall not diminish in any respect whatsoever its right to rely on such representations and warranties.

-46-

Section 9.08 Separability. Should any clause, sentence, paragraph, subsection, Section or Article of this Agreement be judicially declared to be invalid, unenforceable or void, such decision will not have the effect of invalidating or voiding the remainder of this Agreement, and the parties hereto agree that the part or parts of this Agreement so held to be invalid, unenforceable or void will be deemed to have been stricken herefrom by the parties hereto, and the remainder will have the same force and effectiveness as if such stricken part or parts had never been included herein.

Section 9.09 Captions. The captions in this Agreement have been inserted for convenience only and shall be given no substantive meaning or significance whatsoever in construing the terms and provisions of this Agreement.

Section 9.10 Limitation by Law. All provisions of this Agreement and the other Loan Documents are intended to be subject to all applicable mandatory provisions of law which may be controlling and to be limited to the extent necessary so that they will not render this Agreement or any other Loan Document invalid or unenforceable, in whole or in part, or not entitled to be recorded, registered or filed under the provisions of any applicable law.

Section 9.11 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 9.12 Governing Law. This Agreement shall be governed by, and construed in accordance with, the laws of the State of Texas and applicable federal law; provided, however, notwithstanding the foregoing or any other provision of this Agreement, nothing in this Agreement, the Notes or the other Loan Documents shall be deemed to constitute a waiver of any rights which any Bank may have under federal legislation relating to the rate of interest which such Bank may contract for, take, reserve, receive or charge in respect of any Debt owing to such Bank hereunder. Chapter 15, Subtitle 3, Title 79, of the Revised Civil Statutes of Texas, 1925, as amended (relating to revolving loan and revolving triparty accounts), shall not apply to this Agreement or the Notes or the transactions contemplated hereby.

Section 9.13 Limitation on Interest. Each provision in this Agreement and each other Loan Document is expressly limited so that in no event whatsoever shall the amount paid, or otherwise agreed to be paid, by the Borrower for the use, forbearance or detention of the money to be loaned under this Agreement or any other Loan Document or otherwise (including any sums paid as required by any covenant or obligation contained herein or in any other Loan Document which is for the use, forbearance or detention of such money), exceed that amount of money which would cause the effective rate of interest thereon to exceed the Highest Lawful Rate, and all amounts owed under this Agreement and each other Loan Document shall be held to be subject to reduction to the effect that such amounts so paid or agreed to be paid which are for the use, forbearance or detention of money under this Agreement or such Loan Document shall in no event exceed that amount of money which would cause the effective rate of interest thereon to exceed the Highest Lawful Rate. To the extent that the Highest Lawful Rate applicable to a Bank is at any time determined by Texas law, such rate shall be the “indicated rate ceiling” described in the Texas Finance Code, Chapter 303, as amended; provided, however, to the extent permitted by such Finance Code, the Banks from time to time by notice from the Agent to Borrower may revise the aforesaid election of such interest rate ceiling as such ceiling affects the then-current or future balances of the Loans outstanding under the Notes. Notwithstanding any provision in this Agreement or any other Loan Document to the contrary, if the maturity of the Notes or the obligations in respect of the other Loan Documents are accelerated for any reason, or in the event of prepayment of all or any portion of the Notes or the obligations in respect of the other Loan Documents by the Borrower or in any other event, earned interest on the Loans and such other obligations of the Borrower may never exceed the maximum amount permitted by applicable law, and any unearned interest otherwise payable under the Notes or the obligations in respect of the other Loan Documents that is in excess of the maximum amount permitted by applicable law shall be cancelled automatically as of the date of such acceleration or prepayment or other such event and, if theretofore paid, shall be credited on the principal of the Notes or, if the principal of the Notes has been paid in full, refunded to the Borrower. In determining whether or not the interest paid or payable, under any specific contingency, exceeds the Highest Lawful Rate, the Borrower and the Banks shall, to the maximum extent permitted by applicable law, amortize, prorate, allocate and spread, in equal parts during the period of the actual term of this Agreement, all interest at any time contracted for, charged, received or reserved in connection with the Loan Documents.

-47-

Section 9.14 Indemnification. The Borrower agrees to indemnify, defend and hold each member of the Bank Group, as well as their respective officers, employees, agents, Affiliates, directors and shareholders (collectively, “Indemnified Persons”) harmless from and against any and all loss, liability, damage, judgment, claim, deficiency or reasonable expense (including interest, penalties, reasonable attorneys’ fees and amounts paid in settlement) incurred by or asserted against any Indemnified Person arising out of, in any way connected with, or as a result of (i) the execution and delivery of this Agreement and the other documents contemplated hereby, the performance by the parties hereto and thereto of their respective obligations hereunder and thereunder (including but not limited to the making of the Loans by each Bank) and consummation of the transactions contemplated hereby and thereby, (ii) the actual or proposed use of the proceeds of the Loans, (iii) any violation by the Borrower or any of its Subsidiaries of any Requirement of Law, including but not limited to Environmental Laws, (iv) any member of the Bank Group being deemed an operator of any real or personal property of the Borrower or any of its Subsidiaries in circumstances in which no member of the Bank Group is generally operating or generally exercising control over such property, to the extent such losses, liabilities, damages, judgments, claims, deficiencies or expenses arise out of or result from any Hazardous Materials located in, on or under such property or (v) any claim, litigation, investigation or proceeding relating to any of the foregoing, whether or not any Indemnified Person is a party thereto; provided that such indemnity shall not apply to any such losses, claims, damages, liabilities or related expenses that are determined by a court of competent jurisdiction by final and nonappealable judgment to have resulted from the gross negligence or willful misconduct of, or willful violation of the Loan Documents by, such Indemnified Person. WITHOUT LIMITING ANY PROVISION OF THIS AGREEMENT OR ANY OF THE OTHER LOAN DOCUMENTS, IT IS THE EXPRESS INTENTION OF THE BORROWER THAT EACH INDEMNIFIED PERSON SHALL BE INDEMNIFIED AND HELD HARMLESS AGAINST ANY AND ALL LOSSES, LIABILITIES, CLAIMS, DEFICIENCIES, JUDGMENTS OR REASONABLE EXPENSES ARISING OUT OF OR RESULTING FROM THE ORDINARY NEGLIGENCE (WHETHER SOLE OR CONTRIBUTORY) OR STRICT LIABILITY OF SUCH INDEMNIFIED PERSON. Each Indemnified Person will attempt to consult with the Borrower prior to entering into any settlement of any lawsuit or proceeding that could give rise to a claim for indemnity under this Section 9.14, although nothing herein shall give the Borrower the right to direct or control any such settlement negotiations or any related lawsuit or proceeding on behalf of such Indemnified Party. The obligations of the Borrower under this Section 9.14 shall survive the termination of this Agreement.

-48-

Section 9.15 Submission to Jurisdiction. The Borrower hereby irrevocably submits to the jurisdiction of any Texas state or federal court sitting in Houston, Texas over any action or proceeding arising out of or relating to this Agreement or any of the other Loan Documents, and the Borrower irrevocably agrees that all claims in respect of such action or proceeding may be heard and determined in such Texas state or federal court; provided, however, nothing in this Section 9.15 is intended to waive the right of any member of the Bank Group to remove any such action or proceeding commenced in any such Texas state court to an appropriate Texas federal court to the extent the basis for such removal exists under applicable law. The Borrower irrevocably consents to the service of any and all process in any such action or proceeding by the mailing by certified mail of copies of such process to it at its address specified herein. The Borrower agrees that a final judgment in any such action or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by law. Nothing in this Section 9.15 shall affect the right of any member of the Bank Group to serve legal process in any other manner permitted by law or affect the right of any member of the Bank Group to bring any action or proceeding against the Borrower, or its properties, in the courts of any other jurisdiction.

Section 9.16 WAIVER OF JURY TRIAL. TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, THE BORROWER AND THE BANK GROUP HEREBY IRREVOCABLY AND EXPRESSLY WAIVE ALL RIGHT TO A TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM (WHETHER BASED UPON CONTRACT, TORT, OR OTHERWISE) ARISING OUT OF OR RELATING TO THIS AGREEMENT, THE NOTES, OR ANY OTHER LOAN DOCUMENTS OR THE TRANSACTIONS CONTEMPLATED THEREBY OR THE ACTIONS OF THE BANK GROUP IN THE NEGOTIATION, ADMINISTRATION, OR ENFORCEMENT THEREOF.

Section 9.17 FINAL AGREEMENT OF THE PARTIES. THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS CONSTITUTE A LOAN AGREEMENT FOR PURPOSES OF SECTION 26.02(a) OF THE TEXAS BUSINESS AND COMMERCE CODE, AND REPRESENT THE FINAL AGREEMENT BETWEEN THE PARTIES AND MAY NOT BE CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS OR SUBSEQUENT ORAL AGREEMENTS OF THE PARTIES. THERE ARE NO UNWRITTEN ORAL AGREEMENTS BETWEEN THE PARTIES.

Section 9.18 Patriot Act. Each Bank 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 Bank to identify the Borrower in accordance with the Act.
