     (d) Section headings herein and the other Loan Documents are included for convenience of reference only and shall not affect the interpretation of this Agreement or any other Loan Document.

     (e) Pronouns in masculine, feminine and neuter genders shall be construed to include any other gender, and words in the singular form shall be construed to include the plural and vice versa, unless the context otherwise requires.

     (b) Any Subsidiary of the Borrower (including a newly formed or newly acquired Subsidiary) may be designated (or redesignated) as an Unrestricted Subsidiary if (i) the Administrative Agent shall have received (1) a written request from the Borrower specifying the applicable Subsidiary and such other information as the Administrative Agent may reasonably request, (2) the written consent of the Administrative Agent and the Majority Lenders approving such designation, and (3) a certificate of a Responsible Officer of the Borrower certifying that no Default or Event of Default shall then exist or would result from such designation (after giving effect to such designation), and (ii) such designation is deemed to be an Investment in an amount equal to the fair market value of Borrower’s direct and indirect ownership interest in such Subsidiary and such Investment would be permitted under Section 7.2 to be made at the time of such designation.

ARTICLE II.
THE COMMITMENTS AND CREDIT EXTENSIONS

     SECTION 2.1 Loans. Subject to the terms and conditions set forth herein, each Lender severally agrees to make loans (each such loan, a “Loan”) to the Borrower from time to time on any Business Day during the period from the Closing Date to the Maturity Date, in an aggregate amount not to exceed at any time outstanding the lesser of (x) such Lender’s Percentage Share of the aggregate amount of the Loans requested by the Borrower on such day and (y) such Lender’s Commitment Amount; provided, however, that after giving effect to any borrowing, (i) the aggregate Outstanding Amount of all Loans and L/C Obligations shall not exceed the lesser of (A) the Aggregate Commitments on such date and (B) the Borrowing Base then in effect, and (ii) the aggregate Outstanding Amount of the Loans of any Lender, plus such Lender’s Percentage Share of the Outstanding Amount of all L/C Obligations shall not exceed the lesser of such Lender’s Commitment Amount or such Lender’s Percentage Share of the Borrowing Base. Within the limits of each Lender’s Commitment, and subject to the other terms and conditions hereof, the Borrower may borrow under this Section 2.1, prepay under Section 2.4 and reborrow under this Section 2.1.

     SECTION 2.2 Borrowings, Conversions and Continuations of Loans.

     (a) Each Borrowing, each conversion of Loans from one Type to the other, and each continuation of Loans as the same Type shall be made upon the Borrower’s irrevocable prior written notice to the Administrative Agent in the form of a Notice of Advance. Each such notice must be received by the Administrative Agent not later than 12:00 p.m., central time, (i) three Business Days prior to the requested date of any Borrowing of, conversion to or continuation of LIBO Rate Loans or of any conversion of LIBO Rate Loans to Base Rate Loans, and (ii) on the requested date of any Borrowing of Base Rate Loans. Each Notice of Advance shall be appropriately completed and signed by a Responsible Officer of the Borrower. Each Borrowing of, conversion to or continuation of LIBO Rate Loans shall be in a principal amount of $1,000,000 or a whole multiple of $1,000,000 in excess thereof. Each Borrowing of or conversion to Base Rate Loans shall be in a principal amount of $500,000 or a whole multiple of $100,000 in excess thereof. Each Notice of Advance shall specify (i) whether the Borrower is requesting a Borrowing, a conversion of Loans from one Type to the other, or a continuation of Loans as the same Type, (ii) the requested date of the Borrowing, conversion or continuation, as the case may be (which shall be a Business Day), (iii) the principal amount of Loans to be borrowed, converted or continued, (iv) the Type of Loans to be borrowed or to which existing Loans are to be converted, and (v) if applicable, the duration of the Interest Period with respect thereto. If the Borrower fails to specify a Type of Loan in a Notice of Advance or if the Borrower fails to give a timely notice requesting a conversion or continuation, then the applicable Loans shall be made or continued as, or converted to, Base Rate Loans. Any such automatic conversion to Base Rate Loans shall be effective as of the last day of the Interest Period then in effect with respect to the applicable LIBO Rate Loans. If the Borrower requests a Borrowing of, conversion to, or continuation of LIBO Rate Loans in any such Notice of Advance, but fails to specify an Interest Period, it will be deemed to have specified an Interest Period of one month.

     (b) Following receipt of a Notice of Advance, the Administrative Agent shall promptly notify each Lender of its Percentage Share of the applicable Loans, and if no timely notice of a conversion or continuation is provided by the Borrower, the Administrative Agent shall notify each Lender of the details of any automatic conversion to Base Rate Loans described in the preceding subsection. Each Lender shall make the amount of its Loan available to the Administrative Agent in immediately available funds at the Administrative Agent’s Office not later than 2:00 p.m. central time, on the Business Day specified in the applicable Notice of Advance. Upon satisfaction of the applicable conditions set forth in Section 4.2 (and, if such Borrowing is the initial Credit Extension, Section 4.1), the Administrative Agent shall make all funds so received available to the Borrower in like funds as received by the Administrative Agent either by (i) crediting the account of the Borrower on the books of BMO with the amount of such funds or (ii) wire transfer of such funds, in each case in accordance with instructions provided to the Administrative Agent by the Borrower; provided, however, that if, on the date of the Borrowing there are L/C Borrowings outstanding, then the proceeds of such Borrowing shall be applied, first, to the payment in full of any such L/C Borrowings, and second, to the Borrower as provided above. Unless the Administrative Agent shall have received prompt notice from a Lender that such Lender will not make available to the Administrative Agent such Lender’s Loans, the Administrative Agent may in its discretion assume that such Lender has made such

Loans available to the Administrative Agent in accordance with this section and the Administrative Agent may if it chooses, in reliance upon such assumption, make such Loan available to the Borrower. If and to the extent such Lender shall not so make its Loan available to the Administrative Agent, such Lender and the Borrower severally agree to pay or repay to the Administrative Agent within two Business Days after demand the amount of such Loan together with interest thereon, for each day from the date such amount is made available to the Borrower until the date such amount is paid or repaid to the Administrative Agent, to be calculated as to such Lender at the Federal Funds Rate, and to be calculated as to the Borrower at the interest rate applicable at the time to the other Loans made on such date. If any Lender fails to make such payment to the Administrative Agent within such two Business Day period, such Lender shall in addition to such amount pay interest thereon, for each day from the date such Loan is made available to the Borrower until the date such amount is paid or repaid to the Administrative Agent, at the interest rate applicable at the time to the other Loans made on such date. The failure of any Lender to make any Loan to be made by it hereunder shall not relieve any other Lender of its obligation hereunder, if any, to make its Loan, but no Lender shall be responsible for the failure of any other Lender to make any Loan to be made by such other Lender.

     (c) Except as otherwise provided herein, a LIBO Rate Loan may be continued or converted only on the last day of the Interest Period for such LIBO Rate Loan. During the existence of a Default, Event of Default or Borrowing Base Deficiency, no Loans may be requested as, converted to or continued as LIBO Rate Loans.

     (d) The Administrative Agent shall promptly notify the Borrower and the Lenders of the interest rate applicable to any LIBO Rate Loan upon determination of such interest rate. The determination of the LIBO Rate by the Administrative Agent shall be conclusive in the absence of manifest error. The Administrative Agent shall notify the Borrower and the Lenders of any change in BMO’s prime rate used in determining the Base Rate promptly following the public announcement of such change.

     (e) After giving effect to all Borrowings, all conversions of Loans from one Type to the other, and all continuations of Loans as the same Type, there shall not be more than ten (10) LIBO Interest Periods in effect with respect to Loans.

     SECTION 2.3 Letters of Credit.

     2.3.1 The Letter of Credit Commitment.

     (i) Subject to the terms and conditions set forth herein, (A) the Issuing Bank agrees, in reliance upon the agreements of the other Lenders set forth in this Section 2.3, (1) from time to time on any Business Day during the period from the Closing Date until the Letter of Credit Availability Expiration Date, to issue Letters of Credit for the account of the Borrower and in the name of the Borrower or any of its Restricted Subsidiaries, and to amend or renew Letters of Credit previously issued by it, in accordance with subsection 2.3.2 below, and (2) to honor drafts under the Letters of Credit; and (B) the Lenders severally agree to participate in Letters of Credit issued for the account of the Borrower; provided that the Issuing Bank shall not be obligated to make any L/C Credit Extension with respect to any Letter of Credit, and no Lender shall be obligated to

participate in, any Letter of Credit if as of the date of such L/C Credit Extension, (w) with respect to any renewal, extension or amendment to any previously issued Letter of Credit, the Restricted Subsidiary in whose name such Letter of Credit was originally issued (or was most recently renewed, extended or amended, if applicable) has become, or been redesignated as, an Unrestricted Subsidiary, (x) the Outstanding Amount of all L/C Obligations and all Loans would exceed the lesser of (A) the Aggregate Commitments on such date and (B) the Borrowing Base then in effect, (y) the aggregate Outstanding Amount of the Loans of any Lender, plus such Lender’s Percentage Share of the Outstanding Amount of all L/C Obligations would exceed the lesser of (A) such Lender’s Commitment Amount or (B) such Lender’s Percentage Share of the Borrowing Base then in effect, or (z) the Outstanding Amount of the L/C Obligations would exceed the Letter of Credit Sublimit. Within the foregoing limits, and subject to the terms and conditions hereof, the Borrower’s ability to obtain Letters of Credit shall be fully revolving, and accordingly the Borrower may, during the foregoing period, obtain Letters of Credit to replace Letters of Credit that have expired or that have been drawn upon and reimbursed.

     (ii) The Issuing Bank shall be under no obligation to issue any Letter of Credit if:

     (A) the expiry date of such requested Letter of Credit would occur more than twelve months after the date of issuance or last renewal, unless the Majority Lenders acting in their sole discretion have approved in writing such expiry date;

     (B) the expiry date of such requested Letter of Credit would occur after the Letter of Credit Availability Expiration Date, unless all the Lenders acting in their sole discretion have approved in writing such expiry date;

     (C) the issuance of such Letter of Credit would violate one or more policies of the Issuing Bank;

     (D) such Letter of Credit is in a face amount less than $100,000, or denominated in a currency other than Dollars, unless all the Lenders acting in their sole discretion have approved in writing the issuance of Letters of Credit denominated in a currency other than Dollars; or

     (E) such Letter of Credit is to be used directly or indirectly to assure payment of or otherwise support any Person’s Indebtedness for borrowed money;

     (F) the issuance of such Letter of Credit is not in compliance with all applicable governmental restrictions, policies, and guidelines (whether or not having the force of law) or it subjects the Issuing Bank to any cost not anticipated by the Issuing Bank on the date hereof;

     (G) the form and terms of such Letter of Credit are not acceptable to the Administrative Agent and Issuing Bank in their sole and absolute discretion; and

     (H) any other condition in this Agreement to the issuance of such Letter of Credit has not been satisfied.

     (iii) The Issuing Bank shall be under no obligation to amend any Letter of Credit if (A) the Issuing Bank would have no obligation at such time to issue such Letter of Credit in its amended form under the terms hereof, or (B) the beneficiary of such Letter of Credit does not accept the proposed amendment to such Letter of Credit.

     2.3.2 Procedures for Issuance and Amendment of Letters of Credit.

     (i) Each Letter of Credit shall be issued or amended, as the case may be, upon the request of the Borrower delivered to the Issuing Bank (with a copy to the Administrative Agent) in the form of a Letter of Credit Application, appropriately completed and signed by a Responsible Officer of the Borrower. Such Letter of Credit Application must be received by the Issuing Bank and the Administrative Agent not later than 12:00 p.m., central time at least two Business Days (or such later date and time as the Issuing Bank may agree in a particular instance in its sole discretion) prior to the proposed issuance date or date of amendment, as the case may be. In the case of a request for an initial issuance of a Letter of Credit, such Letter of Credit Application shall specify in form and detail satisfactory to the Issuing Bank: (A) the proposed issuance date of the requested Letter of Credit (which shall be a Business Day); (B) the amount thereof; (C) the expiry date thereof; (D) the name and address of the beneficiary thereof; (E) the documents to be presented by such beneficiary in case of any drawing thereunder; (F) the full text of any certificate to be presented by such beneficiary in case of any drawing thereunder; and (G) such other matters as the Issuing Bank may require. In the case of a request for an amendment of any outstanding Letter of Credit, such Letter of Credit Application shall specify in form and detail satisfactory to the Issuing Bank (w) the Letter of Credit to be amended; (x) the proposed date of amendment thereof (which shall be a Business Day); (y) the nature of the proposed amendment; and (z) such other matters as the Issuing Bank may require.

     (ii) Promptly after receipt of any Letter of Credit Application, the Issuing Bank will confirm with the Administrative Agent (by telephone or in writing) that the Administrative Agent has received a copy of such Letter of Credit Application from the Borrower and, if not, the Issuing Bank will provide the Administrative Agent with a copy thereof. Upon receipt by the Issuing Bank of confirmation from the Administrative Agent that the requested issuance or amendment is permitted in accordance with the terms hereof, then, subject to the terms and conditions hereof, the Issuing Bank shall, on the requested date, issue a Letter of Credit for the account of the Borrower or enter into the applicable amendment, as the case may be, in each case in accordance with the Issuing Bank’s usual and customary business practices. Immediately upon the issuance of each Letter of Credit, each Lender shall be deemed to, and hereby irrevocably and unconditionally agrees to and hereby does, purchase from the Issuing Bank a

participation in such Letter of Credit in an amount equal to the product of such Lender’s Percentage Share times the amount of such Letter of Credit.

     2.3.3 Drawings and Reimbursements; Funding of Participations.

     (i) Upon any drawing under any Letter of Credit, the Issuing Bank shall notify the Borrower and the Administrative Agent thereof. Not later than 12:00 p.m., central time, on the date of any payment by the Issuing Bank under a Letter of Credit (each such date, an “Honor Date”), the Borrower shall reimburse the Issuing Bank through the Administrative Agent in an amount equal to the amount of such drawing. If the Borrower fails to so reimburse the Issuing Bank by such time, the Administrative Agent shall promptly notify each Lender of the Honor Date, the amount of the unreimbursed drawing (the “Unreimbursed Amount”), and such Lender’s Percentage Share thereof. In such event, the Borrower shall be deemed to have requested a Borrowing of Base Rate Loans to be disbursed on the Honor Date in an amount equal to the Unreimbursed Amount, without regard to the minimum and multiples specified in Section 2.2 for the principal amount of Base Rate Loans, but subject to the amount of the unutilized portion of the lesser of (x) the Aggregate Commitments and (y) the Borrowing Base then in effect and the conditions set forth in Section 4.2 (other than the delivery of a Notice of Advance). Any notice given by the Issuing Bank or the Administrative Agent pursuant to this Section 2.3.3(i) may be given by telephone if immediately confirmed in writing; provided that the lack of such an immediate confirmation shall not affect the conclusiveness or binding effect of such notice.

     (ii) Each Lender (including the Lender acting as Issuing Bank) shall upon any notice from the Administrative Agent pursuant to Section 2.3.3(i) make funds available to the Administrative Agent for the account of the Issuing Bank at the Administrative Agent’s Office in an amount equal to such Lender’s Percentage Share of the Unreimbursed Amount not later than 1:00 p.m., central time, on the Business Day specified in such notice by the Administrative Agent, whereupon, subject to the provisions of Section 2.3.3(iii), each Lender that so makes funds available shall be deemed to have made a Base Rate Loan to the Borrower in such amount. The Administrative Agent shall remit the funds so received to the Issuing Bank.

     (iii) With respect to any Unreimbursed Amount that is not fully refinanced by a Borrowing of Base Rate Loans because the conditions set forth in Section 4.2 cannot be satisfied or for any other reason, the Borrower shall be deemed to have incurred from the Issuing Bank an L/C Borrowing in the amount of the Unreimbursed Amount that is not so refinanced, which L/C Borrowing shall be due and payable on demand (together with interest) and shall bear interest at the Default Rate. In such event, each Lender’s payment to the Administrative Agent for the account of the Issuing Bank pursuant to Section 2.3.3(ii) shall be deemed payment in respect of its participation in such L/C Borrowing and shall constitute an L/C Advance from such Lender in satisfaction of its participation obligation under this Section 2.3.3.

     (iv) Until each Lender funds its Loan or L/C Advance pursuant to this Section 2.3.3 to reimburse the Issuing Bank for any amount drawn under any Letter of

Credit, interest in respect of such Lender’s Percentage Share of such amount shall be solely for the account of the Issuing Bank.

     (v) Each Lender’s obligation to make Loans or L/C Advances to reimburse the Issuing Bank for amounts drawn under Letters of Credit, as contemplated by this Section 2.3.3, shall be absolute and unconditional and shall not be affected by any circumstance, including (A) any set-off, counterclaim, recoupment, defense or other right which such Lender may have against the Issuing Bank, the Borrower or any other Person for any reason whatsoever; (B) the occurrence or continuance of a Default or Event of Default, or (C) any other occurrence, event or condition, whether or not similar to any of the foregoing. Any such reimbursement shall not relieve or otherwise impair the obligation of the Borrower to reimburse the Issuing Bank for the amount of any payment made by the Issuing Bank under any Letter of Credit, together with interest as provided herein.

     (vi) If any Lender fails to make available to the Administrative Agent for the account of the Issuing Bank any amount required to be paid by such Lender pursuant to the foregoing provisions of this Section 2.3.3 by the time specified in Section 2.3.3(ii), the Issuing Bank shall be entitled to recover from such Lender (acting through the Administrative Agent), on demand, such amount with interest thereon for the period from the date such payment is required to the date on which such payment is immediately available to the Issuing Bank at a rate per annum equal to (1) for the first two Business Days immediately following the date such payment is required, the Federal Funds Rate from time to time in effect, and (2) for each day thereafter, the Base Rate from time to time in effect. A certificate of the Issuing Bank submitted to any Lender (through the Administrative Agent) with respect to any amounts owing under this clause (vi) shall be conclusive absent manifest error.

     2.3.4 Repayment of Participations.

     (i) At any time after the Issuing Bank has made a payment under any Letter of Credit and has received from any Lender such Lender’s L/C Advance in respect of such payment in accordance with Section 2.3.3, if the Administrative Agent receives for the account of the Issuing Bank any payment related to such Letter of Credit (whether directly from the Borrower or otherwise, including proceeds of Cash Collateral applied thereto by the Administrative Agent), or any payment of interest thereon, the Administrative Agent will distribute to such Lender its Percentage Share thereof in the same funds as those received by the Administrative Agent.

     (ii) If any payment received by the Administrative Agent for the account of the Issuing Bank pursuant to Section 2.3.3 is required to be returned, each Lender shall pay to the Administrative Agent for the account of the Issuing Bank its Percentage Share thereof on demand of the Administrative Agent, plus interest thereon from the date of such demand to the date such amount is returned by such Lender, at a rate per annum equal to (1) with respect to the first two Business Days immediately following such demand, the Federal Funds Rate from time to time in effect, and (2) with respect to each day thereafter, the Base Rate from time to time in effect.

     2.3.5 Obligations Absolute. The obligation of the Borrower to reimburse the Issuing Bank for each drawing under each Letter of Credit, and to repay each L/C Borrowing and each drawing under a Letter of Credit that is refinanced by a Borrowing of Loans, shall be absolute, unconditional and irrevocable, and shall be paid strictly in accordance with the terms of this Agreement under all circumstances, including the following:

     (i) any lack of validity or enforceability of such Letter of Credit, this Agreement, or any other agreement or instrument relating thereto;

     (ii) the existence of any claim, counterclaim, set-off, defense or other right that the Borrower may have at any time against any beneficiary or any transferee of such Letter of Credit (or any Person for whom any such beneficiary or any such transferee may be acting), the Issuing Bank or any other Person, whether in connection with this Agreement, the transactions contemplated hereby or by such Letter of Credit or any agreement or instrument relating thereto, or any unrelated transaction;

     (iii) any draft, demand, certificate or other document presented under such Letter of Credit proving to be forged, fraudulent, invalid or insufficient in any respect or any statement therein being untrue or inaccurate in any respect; or any loss or delay in the transmission or otherwise of any document required in order to make a drawing under such Letter of Credit;

     (iv) any payment by the Issuing Bank under such Letter of Credit against presentation of a draft or certificate that does not strictly comply with the terms of such Letter of Credit; or any payment made by the Issuing Bank under such Letter of Credit to any Person purporting to be a trustee in bankruptcy, debtor-in-possession, assignee for the benefit of creditors, liquidator, receiver or other representative of or successor to any beneficiary or any transferee of such Letter of Credit, including any arising in connection with any proceeding under any Debtor Relief Law; or

     (v) any other circumstance or happening whatsoever, whether or not similar to any of the foregoing, including any other circumstance that might otherwise constitute a defense available to, or a discharge of, the Borrower.

     The Borrower shall promptly examine a copy of each Letter of Credit and each amendment thereto that is delivered to it and, in the event of any claim of noncompliance with the Borrower’s instructions or other irregularity, the Borrower will promptly notify the Issuing Bank. The Borrower shall be conclusively deemed to have waived any such claim against the Issuing Bank and its correspondents unless such notice is given as aforesaid.

     2.3.6 Role of Issuing Bank; Indemnity. Each Lender and the Borrower agree that, in paying any drawing under a Letter of Credit, the Issuing Bank shall not have any responsibility to obtain any document (other than any sight draft, certificates and documents expressly required by the Letter of Credit) or to ascertain or inquire as to the validity or accuracy of any such document or the authority of the Person executing or delivering any such document. No Agent-Related Person nor any of the respective correspondents, participants or assignees of the Issuing

Bank shall be liable to any Lender for (i) any action taken or omitted in connection herewith at the request or with the approval of the Lenders or the Majority Lenders, as applicable; (ii) any action taken or omitted in the absence of gross negligence or willful misconduct; or (iii) the due execution, effectiveness, validity or enforceability of any document or instrument related to any Letter of Credit or Letter of Credit Application. The Borrower hereby assumes all risks of the acts or omissions of any beneficiary or transferee with respect to its use of any Letter of Credit. No Agent-Related Person, nor any of the respective correspondents, participants or assignees of the Issuing Bank, shall be liable or responsible for any of the matters described in clauses (i) through (v) of Section 2.3.5. The Borrower agrees to hold Issuing Bank and each Lender harmless and indemnified against any liability or claim in connection with or arising out of the subject matter of this section, WHICH INDEMNITY SHALL APPLY WHETHER OR NOT ANY SUCH LIABILITY OR CLAIM IS IN ANY WAY OR TO ANY EXTENT CAUSED, IN WHOLE OR IN PART, BY ANY NEGLIGENT ACT OR OMISSION OF ANY KIND BY ISSUING BANK OR ANY LENDER, provided only that the Issuing Bank or such Lender shall not be entitled to indemnification for that portion, if any, of any liability or claim which is proximately caused by its own individual gross negligence or willful misconduct as determined in a final judgment. In furtherance and not in limitation of the foregoing, the Issuing Bank may accept documents that appear on their face to be in order, without responsibility for further investigation, regardless of any notice or information to the contrary, and the Issuing Bank shall not be responsible for the validity or sufficiency of any instrument transferring or assigning or purporting to transfer or assign a Letter of Credit or the rights or benefits thereunder or proceeds thereof, in whole or in part, which may prove to be invalid or ineffective for any reason. If any Letter of Credit provides that it is transferable, the Issuing Bank shall have no duty to determine the proper identity of anyone appearing as transferee of such Letter of Credit, nor shall the Issuing Bank be charged with responsibility of any nature or character for the validity or correctness of any transfer or successive transfers, and payment by the Issuing Bank to any purported transferee or transferees as determined by the Issuing Bank is hereby authorized and approved, and the Borrower further agrees to hold the Issuing Bank and each Lender harmless and indemnified against any liability or claim in connection with or arising out of the foregoing, WHICH INDEMNITY SHALL APPLY WHETHER OR NOT ANY SUCH LIABILITY OR CLAIM IS IN ANY WAY OR TO ANY EXTENT CAUSED, IN WHOLE OR IN PART, BY ANY NEGLIGENT ACT OR OMISSION OF ANY KIND BY THE ISSUING BANK OR ANY LENDER, provided only that the Issuing Bank or such Lender shall not be entitled to indemnification for that portion, if any, of any liability or claim which is caused by its own individual gross negligence or willful misconduct. All of Borrower’s Obligations under this Section 2.3.6 shall survive termination of the Commitments or of this Agreement and repayment in full of the Obligations.

     2.3.7 Applicability of ISP98 and UCP. Unless otherwise expressly agreed by the Issuing Bank and the Borrower when a Letter of Credit is issued, (i) the rules of the “International Standby Practices 1998” published by the Institute of International Banking Law & Practice (or such later version thereof as may be in effect at the time of issuance) shall apply to each standby Letter of Credit, and (ii) the rules of the Uniform Customs and Practice for Documentary Credits, as most recently published by the International Chamber of Commerce (the “ICC”) at the time of issuance (including the ICC decision published by the Commission on

Banking Technique and Practice on April 6, 1998 regarding the European single currency (euro)) shall apply to each commercial Letter of Credit.

     2.3.8 Letter of Credit Fees. The Borrower shall pay to the Administrative Agent for the account of each Lender in accordance with its Percentage Share a Letter of Credit fee for each Letter of Credit equal to the LIBOR Spread then in effect with respect to Loans after giving effect to the L/C Obligations incurred with respect to such Letter of Credit times the actual daily maximum amount available to be drawn under such Letter of Credit. Such fee for each Letter of Credit shall be due and payable on the last Business Day of each March, June, September and December, commencing with the first such date to occur after the issuance of such Letter of Credit, and on the Letter of Credit Availability Expiration Date. If there is any change in the LIBOR Spread during any quarter, the actual daily amount of each Letter of Credit shall be computed and multiplied by the LIBOR Spread with respect to Letters of Credit separately for each period during such quarter that such LIBOR Spread was in effect.

     2.3.9 Letter of Credit Fronting Fee and Documentary and Processing Charges Payable to Issuing Bank. The Borrower shall pay directly to the Issuing Bank for its own account a fronting fee in an amount equal to 0.1875% per annum on the daily maximum amount available to be drawn thereunder, due and payable quarterly in arrears on the last Business Day of each March, June, September and December, commencing with the first such date to occur after the issuance of such Letter of Credit, and on the Letter of Credit Availability Expiration Date; provided that all such fees shall be payable on the date on which the Commitments terminate and any such fees accruing after the date on which the Commitments terminate shall be payable on demand. In addition, the Borrower shall pay directly to the Issuing Bank for its own account the customary issuance, presentation, amendment and other processing fees, and other standard costs and charges, of the Issuing Bank relating to letters of credit as from time to time in effect. Such fees and charges are due and payable on demand and are nonrefundable. All participation fees and fronting fees shall be computed on the basis of a year of 360 days and shall be payable for the actual number of days elapsed (including the first day but excluding the last day).

     2.3.10 Conflict with Letter of Credit Application. In the event of any conflict between the terms hereof and the terms of any Letter of Credit Application, the terms hereof shall control.

     2.3.11 L/C Collateral.

     (a) L/C Obligations in Excess of Borrowing Base. (i) If, after the making of all mandatory prepayments required under Section 2.4.2, the aggregate amount of all Loans outstanding plus all L/C Obligations outstanding excluding L/C Obligations secured by cash collateral pursuant to this Section 2.3.11 will exceed the Borrowing Base, then the Borrower will immediately pay to the Issuing Bank an amount in cash equal to such excess, or (ii) should any L/C Obligations remain outstanding on the Maturity Date, then the Borrower will immediately pay the Issuing Bank an amount in cash equal to the aggregate amount of such Issuing Bank’s L/C Obligations. The Issuing Bank will hold such amount as security for the remaining L/C Obligations (“L/C Collateral”) until such L/C Obligations become Matured L/C Obligations, at which time such L/C Collateral may be applied to such Matured L/C Obligations. Neither this subsection nor the following subsection shall, however, limit or impair any rights which the Issuing Bank may have under any other document or agreement relating to any Letter of Credit

or L/C Obligation, including any Letter of Credit Application, or any rights which the Issuing Bank or Lenders may have to otherwise apply any payments by the Borrower and L/C Collateral under Section 2.3.11.

     (b) Acceleration of L/C Obligations. If the Obligations or any part thereof become immediately due and payable pursuant to Section 8.2 then, unless the Majority Lenders otherwise specifically elect to the contrary (which election may thereafter be retracted by the Majority Lenders at any time), all L/C Obligations shall become immediately due and payable without regard to whether or not actual drawings or payments on the Letters of Credit have occurred, and the Borrower shall be obligated to pay to the Issuing Bank immediately an amount equal to the aggregate L/C Obligations which are then outstanding. All amounts so paid shall first be applied to Matured L/C Obligations and then held by the Issuing Bank as L/C Collateral until such L/C Obligations become Matured L/C Obligations, at which time such L/C Collateral shall be applied to such Matured L/C Obligations.

     (c) Investment of L/C Collateral. Pending application thereof, all L/C Collateral shall be invested by the Issuing Bank in such blocked account as the Issuing Bank may choose in its sole discretion reasonably exercised. All interest on such investments shall be reinvested or applied to Matured L/C Obligations. When all Obligations have been satisfied in full, including all L/C Obligations, all Letters of Credit have expired or been terminated, and all of the Borrower’s reimbursement obligations in connection therewith have been satisfied in full, the Issuing Bank shall release any remaining L/C Collateral. The Borrower hereby assigns and grants to the Issuing Bank a continuing security interest in all L/C Collateral paid by it to the Issuing Bank, all investments purchased with such L/C Collateral, and all proceeds thereof to secure its Matured L/C Obligations and its Obligations under this Agreement, the Notes, and the other Loan Documents, and the Borrower agrees that such L/C Collateral and investments shall be subject to all of the terms and conditions of the Borrower’s Security Agreement. The Borrower further agrees that the Issuing Bank shall have all of the rights and remedies of a secured party under the Uniform Commercial Code as adopted in the State of New York with respect to such security interest and that an Event of Default under this Agreement shall constitute a default for purposes of such security interest.

     2.3.12 Calculations. A written advice setting forth in reasonable detail the amounts owing under this section, submitted by the Issuing Bank to the Borrower or any Lender from time to time, shall be conclusive, absent manifest error, as to the amounts thereof.

     SECTION 2.4 Prepayments.

     2.4.1 Voluntary Prepayments. The Borrower may, upon notice to the Administrative Agent, at any time or from time to time voluntarily prepay Loans in whole or in part without premium or penalty; provided that (i) such notice must be received by the Administrative Agent not later than 12:00 p.m., central time, (A) three Business Days prior to any date of prepayment of LIBO Rate Loans, and (B) on the date of prepayment of Base Rate Loans; (ii) any prepayment of LIBO Rate Loans shall be in a principal amount of $1,000,000 or a whole multiple of $1,000,000 in excess thereof; and (iii) any prepayment of Base Rate Loans shall be in a principal amount of $500,000 or a whole multiple of $100,000 in excess thereof. Each such notice shall specify the date and amount of such prepayment and the Type(s) of Loans to be prepaid. The

Administrative Agent will promptly notify each Lender of its receipt of each such notice, and of such Lender’s Percentage Share of such prepayment. If such notice is given by the Borrower, the Borrower shall make such prepayment and the payment amount specified in such notice shall be due and payable on the date specified therein. Any prepayment of a LIBO Rate Loan shall be accompanied by all accrued interest thereon, together with any additional amounts required pursuant to Section 3.5. Each such prepayment shall be applied to the Loans of the Lenders in accordance with their respective Percentage Shares.

     2.4.2 Mandatory Prepayments. The Borrower shall make the following prepayments of the Loans:

     (i) Outstandings Exceed Commitments. If for any reason the Outstanding Amount of all Loans and L/C Obligations at any time exceeds the Aggregate Commitments then in effect, the Borrower shall first immediately prepay Loans and second following repayment of the Loans, Cash Collateralize the L/C Obligations in an aggregate amount equal to such excess.

     (ii) Borrowing Base Deficiency.

     (A) If at any time the aggregate unpaid principal balance of the Loans plus the aggregate amount of L/C Obligations exceeds the Borrowing Base (a “Borrowing Base Deficiency”), the Borrower shall, within thirty (30) days after the Administrative Agent sends written notice of such fact to the Borrower, (1) prepay the principal of the Loans (and, upon prepayment of all Loans, shall, to the extent required, provide L/C Collateral as set forth in Section 2.3.11) in an aggregate amount at least equal to such Borrowing Base Deficiency (in this section, a “Mandatory Prepayment Amount”), or (2) give notice to the Administrative Agent electing to prepay such Mandatory Prepayment Amount in six (6) (or fewer) monthly installments. Each such installment shall equal or exceed one-sixth of such Borrowing Base Deficiency; the first such installment shall be paid within thirty (30) days of the giving of such notice of the Borrowing Base Deficiency by the Administrative Agent to the Borrower and the five (or fewer) subsequent installments shall be due and payable at one month intervals thereafter until such Borrowing Base Deficiency has been eliminated.

     (B) If (1) at any time during the existence or continuation of a Borrowing Base Deficiency, the Borrower or any Guarantor makes a Disposition of assets (other than those described in clauses (a) through (d) of Section 7.5 hereof), or (2) a Disposition of assets included in the Borrowing Base results in a reduction of the Borrowing Base in accordance with Section 7.5(e) such that a Borrowing Base Deficiency occurs, then, in either case, the Borrower shall, or shall cause such Guarantor to, use the Net Sale Proceeds from such Disposition (whether or not such assets are included in the Borrowing Base) to prepay the Loans and, upon prepayment of all Loans, shall provide L/C Collateral as set

forth in Section 2.3.11, within one (1) Business Day of such Disposition in an amount equal to 100% of the Borrowing Base Deficiency then existing or occurring as a result of such disposition. Application of such Net Sale Proceeds shall be applied to the principal amount of the Loans until the Loans are paid in full and then shall be held as L/C Collateral in an amount equal to the aggregate amount of L/C Obligations pursuant to Section 2.3.11.

     SECTION 2.5 Reduction or Termination of Commitments and Maximum Loan Amount. The Borrower may, upon notice to the Administrative Agent, terminate the Aggregate Commitments and the Maximum Loan Amount, or permanently reduce the Aggregate Commitments and the Maximum Loan Amount to an amount not less than the then Outstanding Amount of all Loans and L/C Obligations; provided that (i) any such notice shall be received by the Administrative Agent not later than 12:00 p.m., central time three (3) Business Days prior to the date of termination or reduction, and (ii) any such partial reduction shall be in an aggregate amount of $5,000,000 or any whole multiple of $1,000,000 in excess thereof. The Administrative Agent shall promptly notify the Lenders of any such notice of reduction or termination of the Aggregate Commitments and the Maximum Loan Amount. Once reduced in accordance with this Section, the Commitments may not be increased except in accordance with Section 2.15. Any reduction of the Aggregate Commitments shall be applied to the Commitment Amount of each Lender according to its Percentage Share. All commitment fees accrued until the effective date of any termination of the Aggregate Commitments shall be paid on the effective date of such termination.

     SECTION 2.6 Repayment of Loans. The Borrower shall repay to the Lenders on the Maturity Date the aggregate principal amount of Loans outstanding on such date.

     SECTION 2.7 Initial Borrowing Base. On any date during the period from the Closing Date to the first Evaluation Date, the Borrowing Base shall be an amount equal to $400,000,000.

     SECTION 2.8 Subsequent Determinations of Borrowing Base.

     (a) By each Evaluation Date, the Borrower shall furnish to the Administrative Agent and each Lender all information, reports and data which the Administrative Agent has then reasonably requested concerning the Borrower’s and the Guarantors’ businesses and properties (including Borrower’s and the Guarantors’ Oil and Gas Properties and interests and the reserves and production relating thereto), together with the Engineering Report described in Section 6.2(g), if an Engineering Report is then due. Within thirty (30) days after receiving such information, reports and data, or as promptly thereafter as practicable, the Administrative Agent shall recommend a redetermined Borrowing Base to the Lenders. Such recommended Borrowing Base shall become effective upon the receipt by the Administrative Agent of the approval of the Required Borrowing Base Lenders. The failure of a Lender to respond or object to the recommended Borrowing Base within fifteen (15) days after notice thereof is given to such Lender by the Administrative Agent shall be deemed an acceptance and approval of such recommended Borrowing Base by such Lender. If such recommended Borrowing Base is not approved by Required Borrowing Base Lenders within fifteen (15) days after the Administrative

Agent submits the recommended Borrowing Base to the Lenders, then each Lender shall submit in writing to the Administrative Agent, on or within fifteen (15) days after the Administrative Agent notifies the Lenders that the Lenders have not approved any such recommended Borrowing Base, such Lender’s determination of the redetermined Borrowing Base; in such case, the redetermined Borrowing Base shall be the highest amount approved by the Required Borrowing Base Lenders. NOTWITHSTANDING ANYTHING HEREIN TO THE CONTRARY, WITHOUT THE PRIOR WRITTEN APPROVAL OF ALL OF THE LENDERS, SUCH APPROVAL TO BE IN EACH LENDER’S SOLE DISCRETION, THE REDETERMINED BORROWING BASE SHALL NOT BE INCREASED ABOVE THE AMOUNT OF THE BORROWING BASE IN EFFECT IMMEDIATELY PRIOR TO SUCH REDETERMINATION. The Administrative Agent shall by notice to the Borrower and the Lenders designate the amount of the Borrowing Base (determined by the Required Borrowing Base Lenders or all of the Lenders, as applicable, in accordance with the foregoing procedures) available to the Borrower hereunder, which designation shall take effect immediately on the date such notice is sent (a “Determination Date”) and shall remain in effect until but not including the next date as of which the Borrowing Base is redetermined. If the Borrower does not furnish all such information, reports and data by the date specified in the first sentence of this section, the Administrative Agent may nonetheless designate the Borrowing Base at any amount which the Lenders determine, and may redesignate the Borrowing Base from time to time thereafter at any amount which all Lenders redetermine, until each Lender receives all such information, reports and data, whereupon Lenders shall designate a new Borrowing Base as described above. The Lenders shall determine the amount of the Borrowing Base based upon the loan collateral value which they, in their sole discretion and in accordance with their respective normal practices and standards for oil and gas loans as such practices and standards exist at the particular time, assign to the various Oil and Gas Properties of the Borrower or the Guarantors at the time in question and based upon such other factors (including without limitation the assets, liabilities, fixed charges, cash flow, business, properties, prospects, management and ownership of any of the Borrower or the Guarantors or any Subsidiary of any of the Borrower or the Guarantors) as they, in their sole discretion and in accordance with their respective normal practices and standards for oil and gas loans as such practices and standards exist at the particular time, deem significant. It is expressly understood that Lenders and the Administrative Agent have no obligation to agree upon or designate the Borrowing Base at any particular amount, whether in relation to the Maximum Loan Amount or otherwise, and that the Lenders’ commitments to advance funds hereunder is determined by reference to the Borrowing Base from time to time in effect, which Borrowing Base shall be used for calculating commitment fees under Section 2.10(a). Additional redeterminations at the request of the Lenders, the Administrative Agent or the Borrower shall be subject to a $5,000 engineering fee payable by Borrower to the Administrative Agent for its own account.

     (b) The Borrower may include additional Oil and Gas Properties of the Borrower or the Guarantors acquired from time to time as Collateral for the Secured Obligations, which may then be included in the calculation of the Borrowing Base, by the Borrower or such Guarantor (A) giving written notice to the Administrative Agent of such properties to be included, (B) subjecting such properties to Liens securing the Secured Obligations (pursuant to Security Documents satisfactory to the Administrative Agent) if necessary to comply with the provisions of Section 6.16, (C) including such properties in an Engineering Report submitted to the

Administrative Agent and (D) delivering to the Administrative Agent title opinions (or other title reports or title information acceptable to the Administrative Agent) covering at least 80% of the additional value of such properties addressed to the Administrative Agent for the benefit of the Lenders covering all of such properties and other legal opinions from counsel acceptable to the Administrative Agent, in its sole discretion, in form, scope and substance acceptable to the Administrative Agent opining favorably as to, among such other matters as may be required by the Administrative Agent, (1) the Borrower’s or the appropriate Guarantor’s ownership of such properties and (2) matters of the type covered by the opinions delivered pursuant to Section 4.1(a)(vi).

     (c) In addition to the any scheduled determination or discretionary determination of the Borrowing Base, the Borrowing Base shall be automatically reduced from time to time as set forth in Section 7.5(e).

     SECTION 2.9 Interest.

     (a) Subject to the provisions of subsection (b) below, (i) each LIBO Rate Loan shall bear interest on the outstanding principal amount thereof for each Interest Period at a rate per annum equal to the Adjusted LIBO Rate for such Interest Period plus the LIBOR Spread; and (ii) each Base Rate Loan shall bear interest on the outstanding principal amount thereof from the applicable borrowing date at a rate per annum equal to the Base Rate plus the Base Rate Spread.

     (b) (i) While any Event of Default exists or after acceleration, the Borrower shall pay interest on the principal amount of all outstanding Obligations at a fluctuating interest rate per annum at all times equal to the Default Rate, and (ii) while any Borrowing Base Deficiency exists, the Borrower shall pay interest on the principal amount of all outstanding Obligations at a fluctuating interest rate per annum at all times equal to the Borrowing Base Deficiency Rate, in each case, to the fullest extent permitted by applicable Law. Accrued and unpaid interest on past due amounts (including interest on past due interest) shall be due and payable upon demand.

     (c) Interest on each Loan shall be due and payable in arrears on each Interest Payment Date applicable thereto and at such other times as may be specified herein. Interest hereunder shall be due and payable in accordance with the terms hereof before and after judgment, and before and after the commencement of any proceeding under any Debtor Relief Law.

     SECTION 2.10 Fees. In addition to certain fees described in Sections 2.3.8 and 2.3.9:

     (a) Commitment Fee. The Borrower shall pay to the Administrative Agent for the account of each Lender in accordance with its Percentage Share, a commitment fee equal to the Commitment Fee Rate times the actual daily amount by which the lesser of the Aggregate Commitments and the Borrowing Base then in effect exceeds the sum of (i) the Outstanding Amount of Loans and (ii) the Outstanding Amount of L/C Obligations. The commitment fee shall accrue at all times from the Closing Date until the Maturity Date and shall be due and payable quarterly in arrears on the last Business Day of each March, June, September and December, commencing with the first such date to occur after the Closing Date, and on the Maturity Date. The commitment fee shall be calculated quarterly in arrears, and if there is any

change in the Commitment Fee Rate with respect to commitment fees during any quarter, the actual daily amount shall be computed and multiplied by the Commitment Fee Rate with respect to commitment fees separately for each period during such quarter that such Commitment Fee Rate was in effect. The commitment fee shall accrue at all times, including at any time during which one or more of the conditions in Article IV is not met.

     (b) Arrangement and Agency Fees. The Borrower shall pay an arrangement fee to the Arranger for the Arranger’s own account, and shall pay an agency fee to the Administrative Agent for the Administrative Agent’s own account, in the amounts and at the times specified in the letter agreement, dated December 15, 2006 (the “Agent and Arranger Fee Letter”), among the Borrower, the Arranger and the Administrative Agent. Such fees shall be fully earned when paid and shall be nonrefundable for any reason whatsoever.

     SECTION 2.11 Computation of Interest and Fees. Computation of interest on Base Rate Loans and commitment fees shall be calculated on the basis of a year of 365 or 366 days, as the case may be, and the actual number of days elapsed. Computation of all other types of interest and all fees shall be calculated on the basis of a year of 360 days and the actual number of days elapsed, which results in a higher yield to the payee thereof than a method based on a year of 365 or 366 days. Interest shall accrue on each Loan for the day on which the Loan is made, and shall not accrue on a Loan, or any portion thereof, for the day on which the Loan or such portion is paid, provided that any Loan that is repaid on the same day on which it is made shall bear interest for one day.

     SECTION 2.12 Notes and Other Evidence of Debt.

     (a) The obligation of the Borrower to repay to each Lender the aggregate amount of all Loans made by such Lender (such Lender’s “Loan”), together with interest accruing in connection therewith, shall be evidenced by a single promissory note (such Lender’s “Note”) made by the Borrower in the amount of such Lender’s Commitment Amount payable to the order of such Lender, which Note shall be substantially in the form of Exhibit B with appropriate insertions. Each Lender may record the date, Type (if applicable), amount and maturity of the applicable Loans and payments with respect thereto in one or more schedules to its Note or on one or more accounts or records maintained by such Lender and by the Administrative Agent in the ordinary course of business. The accounts or records maintained by the Administrative Agent and each Lender shall be conclusive absent manifest error of the amount of the Credit Extensions made by the Lenders to the Borrower and the interest and payments thereon. Any failure so to record or any error in doing so shall not, however, limit or otherwise affect the obligation of the Borrower hereunder to pay any amount owing with respect to the Loans and L/C Obligations.

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

     SECTION 2.13 Payments Generally.

     (a) All payments to be made by the Borrower shall be made without condition or deduction for any counterclaim, defense, recoupment or setoff. Except as otherwise expressly provided herein, all payments by the Borrower hereunder shall be made to the Administrative Agent, for the account of the respective Lenders to which such payment is owed, at the Administrative Agent’s Office in Dollars and in immediately available funds not later than 12:00 noon, central time, on the date specified herein. The Administrative Agent will promptly distribute to each Lender its Percentage Share (or other applicable share as provided herein) of such payment in like funds as received by wire transfer to such Lender’s Lending Office. All payments received by the Administrative Agent after 12:00 noon, central time, shall be deemed received on the next succeeding Business Day and any applicable interest or fee shall continue to accrue.

     (b) Subject to the definition of “Interest Period,” if any payment to be made by the Borrower shall come due on a day other than a Business Day, payment shall be made on the next following Business Day, and such extension of time shall be reflected in computing interest or fees, as the case may be.

     (c) Unless the Borrower or any Lender has notified the Administrative Agent prior to the date any payment is required to be made by it to the Administrative Agent hereunder, that the Borrower or such Lender, as the case may be, will not make such payment, the Administrative Agent may assume that the Borrower or such Lender, as the case may be, has timely made such payment and may (but shall not be so required to), in reliance thereon, make available a corresponding amount to the Person entitled thereto. If and to the extent that such payment was not in fact made to the Administrative Agent in immediately available funds, then:

     (i) if the Borrower failed to make such payment, each Lender shall forthwith on demand repay to the Administrative Agent the portion of such assumed payment that was made available to such Lender in immediately available funds, together with interest thereon (1) in respect of each of the first two Business Days from and including the date such amount was made available by the Administrative Agent to such Lender to the date such amount is repaid to the Administrative Agent in immediately available funds, at the Federal Funds Rate from time to time in effect, and (2) in respect of each day after the first two Business Days from and including the date such amount was made available by the Administrative Agent to such Lender to the date such amount is repaid to the Administrative Agent in immediately available funds, at the Base Rate from time to time in effect; and

     (ii) if any Lender failed to make such payment, such Lender shall forthwith on demand pay to the Administrative Agent the amount thereof in immediately available funds, together with interest thereon for the period from the date such amount was made available by the Administrative Agent to the Borrower to the date such amount is recovered by the Administrative Agent (the “Compensation Period”) at a rate per annum equal to (1) for the first two Business Days of any Compensation Period, the Federal Funds Rate from time to time in effect, and (2) for each other day of any Compensation Period, the interest rate applicable to the applicable Borrowing. If such Lender pays such

amount to the Administrative Agent, then such amount shall constitute such Lender’s Loan included in the applicable Borrowing. If such Lender does not pay such amount forthwith upon the Administrative Agent’s demand therefor, the Administrative Agent may make a demand therefor upon the Borrower, and the Borrower shall pay such amount to the Administrative Agent, together with interest thereon for the Compensation Period at a rate per annum equal to the rate of interest applicable to the applicable Borrowing. Nothing herein shall be deemed to relieve any Lender from its obligation to fulfill its Commitment or to prejudice any rights that the Administrative Agent or the Borrower may have against any Lender as a result of any default by such Lender hereunder.

     A notice of the Administrative Agent to any Lender with respect to any amount owing under this subsection (c) shall be conclusive, absent manifest error.

     (d) If any Lender makes available to the Administrative Agent funds for any Loan to be made by such Lender as provided in the foregoing provisions of this Article II, and the conditions to the applicable Credit Extension set forth in Article IV are not satisfied or waived in accordance with the terms hereof, the Administrative Agent shall return such funds (in like funds as received from such Lender) to such Lender, without interest.

     (e) The obligations of the Lenders hereunder to make Loans and to fund participations in Letters of Credit are several and not joint. The failure of any Lender to make any Loan or to fund any such participation on any date required hereunder shall not relieve any other Lender of its corresponding obligation to do so on such date, and no Lender shall be responsible for the failure of any other Lender to so make its Loan or purchase its participation.

     (f) Nothing herein shall be deemed to obligate any Lender to obtain the funds for any Loan in any particular place or manner or to constitute a representation by any Lender that it has obtained or will obtain the funds for any Loan in any particular place or manner.

     SECTION 2.14 Sharing of Payments. If, other than as expressly provided elsewhere herein, any Lender shall obtain on account of the Loans made by it, or the participations in L/C Obligations held by it, any payment (whether voluntary, involuntary, through the exercise of any right of set-off, or otherwise) in excess of its ratable share (or other share contemplated hereunder) thereof, such Lender shall immediately (a) notify the Administrative Agent of such fact, and (b) purchase from the other Lenders such participations in the Loans made by them and/or such subparticipations in the participations in L/C Obligations held by them, as the case may be, as shall be necessary to cause such purchasing Lender to share the excess payment in respect of such Loan or such participations, as the case may be, pro rata with each of them; provided, however, that if all or any portion of such excess payment is thereafter recovered from the purchasing Lender, such purchase shall to that extent be rescinded and each other Lender shall repay to the purchasing Lender the purchase price paid therefor, together with an amount equal to such paying Lender’s ratable share (according to the proportion of (i) the amount of such paying Lender’s required repayment to (ii) the total amount so recovered from the purchasing Lender) of any interest or other amount paid or payable by the purchasing Lender in respect of the total amount so recovered. The Borrower agrees that any Lender so purchasing a participation from another Lender may, to the fullest extent permitted by law, exercise all its

rights of payment (including the right of set-off, but subject to Section 10.9) with respect to such participation as fully as if such Lender were the direct creditor of the Borrower in the amount of such participation. The Administrative Agent will keep records (which shall be conclusive and binding in the absence of manifest error) of participations purchased under this Section and will in each case notify the Lenders following any such purchases or repayments. Each Lender that purchases a participation pursuant to this Section shall from and after such purchase have the right to give all notices, requests, demands, directions and other communications under this Agreement with respect to the portion of the Obligations purchased to the same extent as though the purchasing Lender were the original owner of the Obligations purchased.

     SECTION 2.15 Increase in Commitment Amounts and Aggregate Commitments.

     (a) Upon prior notice to, and the written consent (which consent shall not be unreasonably withheld or delayed) of, the Administrative Agent (which shall promptly notify the Lenders), the Borrower may from time to time, (i) request that the Lenders increase the Aggregate Commitments pro rata among the Lenders up to an amount not exceeding the Maximum Loan Amount or (ii) invite one or more Lenders to increase its respective Commitment Amount or one or more additional Eligible Assignees to become Lenders party to the Agreement, in each case so as to increase the Aggregate Commitments to an amount not exceeding the Maximum Loan Amount. At the time of sending such notice to the Lenders or any Lender or invitee, the Borrower (in consultation with the Administrative Agent) shall specify the time period within which each Lender or invitee, as applicable, is requested to respond (which shall in no event be less than ten (10) Business Days from the date of delivery of such notice to the Lenders). If the Borrower has requested that the Lenders increase their respective Commitment Amounts pro rata hereunder, each Lender shall notify the Administrative Agent within such time period whether or not it agrees to increase its respective Commitment Amount and, if so, whether by an amount equal to, greater than, or less than its then current Percentage Share of such requested increase and any Lender not responding within such time period shall be deemed to have declined to increase its respective Commitment Amount. Anything herein contained to the contrary notwithstanding, no Lender shall have any obligation whatsoever to increase its respective Commitment Amount hereunder. The consent of the Lenders shall not be required in order for one or more Lender to increase its Commitment Amount hereunder or for any Eligible Assignee to become a party to this Agreement pursuant to this Section 2.15.

     (b) If the Aggregate Commitments are increased in accordance with this Section 2.15, the Administrative Agent and the Borrower shall determine the effective date of such increase (the “Increase Effective Date”). The Administrative Agent and the Borrower shall promptly notify the Lenders of the final allocation of such increase and the Increase Effective Date. Each existing Lender that increases its Commitment Amount and each additional Lender, if any, and the Borrower shall execute and deliver to the Administrative Agent (which the Administrative Agent shall also execute to acknowledge its acceptance thereof) a certificate substantially in the form of Exhibit J hereto (an “Additional Lender Certificate”). Upon receipt by the Administrative Agent of Additional Lender Certificates from existing Lenders or additional Lenders, if any, in an amount sufficient to effectuate the increase requested by the Borrower: (1) the Aggregate Commitments shall be increased, (2) the Administrative Agent shall amend and distribute to the Borrower and the Lenders a revised Schedule 2.1 of the Commitment

Amounts and Percentage Shares of each Lender adding or amending, as applicable, the Commitment Amount and Percentage Share of any Lender executing the Additional Lender Certificate and the revised Percentage Shares of the other Lenders, as applicable (which shall be deemed incorporated into this Agreement), (3) any additional Lender shall be deemed to be a party in all respects to this Agreement and the other Loan Documents to which the Lenders are party as of the Increase Effective Date and (4) upon the Increase Effective Date, any increasing or additional Lender party to the Additional Lender Certificate shall purchase from each of the (other) Lenders party to the Agreement immediately prior to the Increase Effective Date a pro rata portion of the outstanding Loans (and participations L/C Obligations) of each such (other) Lender such that each Lender (including any additional Lender, if any) shall hold its respective Percentage Share of the outstanding Loans (and participations in L/C Obligations) as reflected in the revised Schedule 2.1 required by this Section 2.15, provided that the Borrower shall pay any amounts due under Section 3.5 to the extent that any such purchase gives rise to the costs indemnified thereby.

     (c) As a condition precedent to such increase, the Borrower shall deliver to the Administrative Agent a certificate dated as of the Increase Effective Date (in sufficient copies for each Lender) signed by a Responsible Officer of the Borrower (i) certifying and attaching the resolutions adopted by the Borrower approving or consenting to such increase, (ii) including a Compliance Certificate demonstrating pro forma compliance with Section 7.13 after giving effect to such increase and (iii) certifying that, before and after giving effect to such increase, the representations and warranties contained in Article V are true and correct on and as of the Increase Effective Date and no Default or Event of Default exists. The Borrower shall execute and deliver (1) replacement Notes in accordance with Section 2.12 reflecting such Lender’s Commitment Amount, which Notes shall be dated as of the date of this Agreement and shall otherwise comply with the provisions of Section 2.12, (2) if requested by the Administrative Agent in its sole discretion, amendments or supplements to any of the Security Documents as may be necessary or desirable to reflect the increase in the Aggregate Commitment Amount, and (3) a Form U-1 or an amendment to any previously delivered Form U-1, together with all annexes or schedules thereto and any other documents or information related thereto as may be requested by the Administrative Agent or any Lender, for each Lender duly completed and executed by the Borrower in form and substance acceptable to each Lender (as evidenced by each Lender having executed and returned a copy of its respective Form U-1) demonstrating compliance with Regulation U issued by the Board after giving effect to any increase in the Aggregate Commitments.

     (d) This Section shall supersede any provision in Section 10.1 to the contrary but shall be subject to Section 2.5.

ARTICLE III.
TAXES, YIELD PROTECTION AND ILLEGALITY

     SECTION 3.1 Taxes.

     (a) Any and all payments by the Borrower to or for the account of the Administrative Agent or any Lender under any Loan Document shall be made free and clear of and without deduction for any and all present or future taxes, duties, levies, imposts, deductions, assessments,

fees, withholdings or similar charges, and all liabilities with respect thereto, excluding, in the case of the Administrative Agent and each Lender, taxes imposed on or measured by its net income, and franchise taxes imposed on it (in lieu of net income taxes), by the jurisdiction (or any political subdivision thereof) under the Laws of which the Administrative Agent or such Lender, as the case may be, is organized or maintains a lending office (all such non-excluded taxes, duties, levies, imposts, deductions, assessments, fees, withholdings or similar charges, and liabilities being hereinafter referred to as “Taxes”). If the Borrower shall be required by any Laws to deduct any Taxes from or in respect of any sum payable under any Loan Document to the Administrative Agent or any Lender, (i) the sum payable shall be increased as necessary so that after making all required deductions (including deductions applicable to additional sums payable under this Section), the Administrative Agent and such Lender receives an amount equal to the sum it would have received had no such deductions been made, (ii) the Borrower shall make such deductions, (iii) the Borrower shall pay the full amount deducted to the relevant taxation authority or other authority in accordance with applicable Laws, and (iv) within 30 days after the date of such payment, the Borrower shall furnish to the Administrative Agent (which shall forward the same to such Lender) the original or a certified copy of a receipt evidencing payment thereof.

     (b) In addition, the Borrower agrees to pay any and all present or future stamp, court or documentary taxes and any other excise or property taxes or charges or similar levies which arise from any payment made under any Loan Document or from the execution, delivery, performance, enforcement or registration of, or otherwise with respect to, any Loan Document (hereinafter referred to as “Other Taxes”).

     (c) If the Borrower shall be required to deduct or pay any Taxes or Other Taxes from or in respect of any sum payable under any Loan Document to the Administrative Agent or any Lender, the Borrower shall also pay to the Administrative Agent (for the account of such Lender) or to such Lender, at the time interest is paid, such additional amount that such Lender specifies as necessary to preserve the after-tax yield (after factoring in all taxes, including taxes imposed on or measured by net income) such Lender would have received if such Taxes or Other Taxes had not been imposed.

     (d) The Borrower agrees to indemnify the Administrative Agent and each Lender for (i) the full amount of Taxes and Other Taxes (including any Taxes or Other Taxes imposed or asserted by any jurisdiction on amounts payable under this Section) paid by the Administrative Agent and such Lender, (ii) amounts payable under Section 3.1(c) and (iii) any liability (including penalties, interest and expenses) arising therefrom or with respect thereto, in each case whether or not such Taxes or Other Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority. Payment under this subsection (d) shall be made within 30 days after the date the Lender or the Administrative Agent makes a demand therefor.

     SECTION 3.2 Illegality. If any Lender determines that any Law has made it unlawful, or that any Governmental Authority has asserted that it is unlawful, for any Lender or its applicable Lending Office to make, maintain or fund LIBO Rate Loans, or materially restricts the authority of such Lender to purchase or sell, or to take deposits of, Dollars in the applicable offshore Dollar market, or to determine or charge interest rates based upon the LIBO Rate, then,

on notice thereof by such Lender to the Borrower through the Administrative Agent, any obligation of such Lender to make or continue LIBO Rate Loans or to convert Base Rate Loans to LIBO Rate Loans shall be suspended until such Lender notifies the Administrative Agent and the Borrower that the circumstances giving rise to such determination no longer exist. Upon receipt of such notice, the Borrower shall, upon demand from such Lender (with a copy to the Administrative Agent), prepay or, if applicable, convert all LIBO Rate Loans of such Lender to Base Rate Loans, either on the last day of the Interest Period thereof, if such Lender may lawfully continue to maintain such LIBO Rate Loans to such day, or immediately, if such Lender may not lawfully continue to maintain such LIBO Rate Loans. Upon any such prepayment or conversion, the Borrower shall also pay interest on the amount so prepaid or converted. Each Lender agrees to designate a different Lending Office if such designation will avoid the need for such notice and will not, in the good faith judgment of such Lender, otherwise be materially disadvantageous to such Lender.

     SECTION 3.3 Inability to Determine Rates. If the Administrative Agent determines in connection with any request for a LIBO Rate Loan or a conversion to or continuation thereof that (a) Dollar deposits are not being offered to banks in the applicable offshore Dollar market for the applicable amount and Interest Period of such LIBO Rate Loan, (b) adequate and reasonable means do not exist for determining the LIBO Rate for such LIBO Rate Loan, or (c) the Adjusted LIBO Rate for such LIBO Rate Loan does not adequately and fairly reflect the cost to the Lenders of funding such LIBO Rate Loan, the Administrative Agent will promptly notify the Borrower and all Lenders. Thereafter, the obligation of the Lenders to make or maintain LIBO Rate Loans shall be suspended until the Administrative Agent revokes such notice. Upon receipt of such notice, the Borrower may revoke any pending request for a Borrowing, conversion or continuation of LIBO Rate Loans or, failing that, will be deemed to have converted such request into a request for a Borrowing of Base Rate Loans in the amount specified therein.

     SECTION 3.4 Increased Cost and Reduced Return; Capital Adequacy.

     (a) If any Lender determines that, as a result of the introduction of, or any change in, or in the interpretation of any Law, or such Lender’s compliance therewith, there shall be any increase in the cost to such Lender of agreeing to make or making, funding or maintaining LIBO Rate Loans or (as the case may be) issuing or participating in Letters of Credit, or a reduction in the amount received or receivable by such Lender in connection with any of the foregoing (excluding for purposes of this subsection (a) any such increased costs or reduction in amount resulting from (i) Taxes or Other Taxes (as to which Section 3.1 shall govern), (ii) changes in the basis of taxation of overall net income or overall gross income by the United States or any foreign jurisdiction or any political subdivision of either thereof under the Laws of which such Lender is organized or has its Lending Office, and (iii) reserve requirements utilized, as to LIBO Rate Loans, in the determination of the Adjusted LIBO Rate), then from time to time upon demand of such Lender (with a copy of such demand to the Administrative Agent), the Borrower shall pay to such Lender such additional amounts as will compensate such Lender for such increased cost or reduction.

     (b) If any Lender determines that the introduction of any Law regarding capital adequacy or any change therein or in the interpretation thereof, or compliance by such Lender (or its Lending Office) therewith, has the effect of reducing the rate of return on the capital of such Lender or any corporation controlling such Lender as a consequence of such Lender’s obligations hereunder (taking into consideration its policies with respect to capital adequacy and such Lender’s desired return on capital), then from time to time upon demand of such Lender (with a copy of such demand to the Administrative Agent), the Borrower shall pay to such Lender such additional amounts as will compensate such Lender for such reduction.

     SECTION 3.5 Funding Losses. Upon demand of any Lender (with a copy to the Administrative Agent) from time to time, the Borrower shall promptly compensate such Lender for and hold such Lender harmless from any loss, cost or expense incurred by it as a result of:

     (a) any continuation, conversion, payment or prepayment of any Loan other than a Base Rate Loan on a day other than the last day of the Interest Period for such Loan (whether voluntary, mandatory, automatic, by reason of acceleration, or otherwise); or

     (b) any failure by the Borrower (for a reason other than the failure of such Lender to make a Loan) to prepay, borrow, continue or convert any Loan other than a Base Rate Loan on the date or in the amount notified by the Borrower; or

     (c) any assignment of a LIBO Rate Loan on a day other than the last day of the Interest Period therefor as a result of a request by the Borrower pursuant to Section 3.9;

including any loss of anticipated profits and any loss or expense arising from the liquidation or reemployment of funds obtained by it to maintain such Loan or from fees payable to terminate the deposits from which such funds were obtained. The Borrower shall also pay any customary administrative fees charged by such Lender in connection with the foregoing.

For purposes of calculating amounts payable by the Borrower to the Lenders under this Section 3.5, each Lender shall be deemed to have funded each LIBO Rate Loan made by it at the LIBO Rate for such Loan by a matching deposit or other borrowing in the applicable offshore Dollar interbank market for a comparable amount and for a comparable period, whether or not such LIBO Rate Loan was in fact so funded.

     SECTION 3.6 Matters Applicable to all Requests for Compensation.

     (a) A certificate of the Administrative Agent or any Lender claiming compensation under this Article III and setting forth the additional amount or amounts to be paid to it hereunder shall be conclusive in the absence of manifest error. In determining such amount, the Administrative Agent or such Lender may use any reasonable averaging and attribution methods.

     (b) Upon any Lender’s making a claim for compensation under Section 3.1 or 3.4, the Borrower may remove or replace such Lender in accordance with Section 3.9; provided that the Borrower shall have the right to replace such Lender only if they also replace any other Lender who has made or is making a similar claim for compensation under Section 3.1 or 3.4.

     SECTION 3.7 Survival. All of the Borrower’s obligations under this Article III shall survive termination of the Commitments and of this Agreement and payment in full of all the other Obligations.

     SECTION 3.8 Foreign Lenders. Each Lender that is a “foreign corporation, partnership or trust” within the meaning of the Code (a “Foreign Lender”) shall deliver to the Administrative Agent, prior to receipt of any payment subject to withholding under the Code (or after accepting an assignment of an interest herein), two duly signed completed copies of either IRS Form W-8BEN or any successor thereto (relating to such Person and entitling it to an exemption from, or reduction of, withholding tax on all payments to be made to such Person by the Borrower pursuant to this Agreement) or IRS Form W-8ECI or any successor thereto (relating to all payments to be made to such Person by the Borrower pursuant to this Agreement) or such other evidence satisfactory to the Borrower and the Administrative Agent that such Person is entitled to an exemption from, or reduction of, U.S. withholding tax. Thereafter and from time to time, each such Person shall (a) promptly submit to the Administrative Agent such additional duly completed and signed copies of one of such forms (or such successor forms as shall be adopted from time to time by the relevant United States taxing authorities) as may then be available under then current United States laws and regulations to avoid, or such evidence as is satisfactory to the Borrower and the Administrative Agent of any available exemption from or reduction of, United States withholding taxes in respect of all payments to be made to such Person by the Borrower pursuant to this Agreement, (b) promptly notify the Administrative Agent of any change in circumstances which would modify or render invalid any claimed exemption or reduction, and (c) take such steps as shall not be materially disadvantageous to it, in the reasonable judgment of such Lender, and as may be reasonably necessary (including the re-designation of its Lending Office) to avoid any requirement of applicable Laws that the Borrower make any deduction or withholding for taxes from amounts payable to such Person. If such Person fails to deliver the above forms or other documentation, then the Administrative Agent may withhold from any interest payment to such Person an amount equivalent to the applicable withholding tax imposed by Sections 1441 and 1442 of the Code, without reduction. If any Governmental Authority asserts that the Administrative Agent did not properly withhold any tax or other amount from payments made in respect of such Person, such Person shall indemnify the Administrative Agent therefor, including all penalties and interest, any taxes imposed by any jurisdiction on the amounts payable to the Administrative Agent under this Section, and costs and expenses (including Attorney Costs) of the Administrative Agent. The obligation of the Lenders under this Section shall survive the payment of all Obligations and the resignation or replacement of the Administrative Agent.

     SECTION 3.9 Removal and Replacement of Lenders.

     (a) Under any circumstances set forth herein providing that the Borrower shall have the right to remove or replace a Lender as a party to this Agreement, the Borrower may, upon notice to such Lender and the Administrative Agent, (i) remove such Lender by terminating such Lender’s Commitment or (ii) replace such Lender by causing such Lender to assign its Commitment (and Commitment Amount) (without payment of any assignment fee) pursuant to Section 10.7.2(a) to one or more other Lenders or Eligible Assignees procured by the Borrower; provided, however, that if the Borrower elects to exercise such right with respect to any Lender

pursuant to Section 3.6(b), it shall be obligated to remove or replace, as the case may be, all Lenders that have made similar requests for compensation pursuant to Section 3.1 or 3.4. The Borrower shall (x) pay in full all principal, interest, fees and other amounts owing to such Lender through the date of termination or assignment (including any amounts payable pursuant to Section 3.5), (y) provide appropriate assurances and indemnities (which may include letters of credit) to the Issuing Bank as may reasonably be required with respect to any continuing obligation to purchase participation interests in any L/C Obligations then outstanding, and (z) release such Lender from its obligations under the Loan Documents. Any Lender being replaced shall execute and deliver an Lender Assignment with respect to such Lender’s Commitment, Commitment Amount and outstanding Credit Extensions. The Administrative Agent shall distribute an amended Schedule 2.1, which shall be deemed incorporated into this Agreement, to reflect changes in the identities of the Lenders and adjustments of their respective Commitment Amounts and/or Percentage Shares resulting from any such removal or replacement.

     (b) In order to make all the Lenders’ interests in any outstanding Credit Extensions ratable in accordance with any revised Percentage Shares after giving effect to the removal or replacement of a Lender, the Borrower shall pay or prepay, if necessary, on the effective date thereof, all outstanding Loans of all Lenders, together with any amounts due under Section 3.5. The Borrower may then request Loans from the Lenders in accordance with their revised Percentage Shares. The Borrower may net any payments required hereunder against any funds being provided by any Lender or Eligible Assignee replacing a terminating Lender. The effect for purposes of this Agreement shall be the same as if separate transfers of funds had been made with respect thereto.

     (c) This section shall supersede any provision in Section 10.1 to the contrary.

     (a) neither any property of any Loan Party or any Subsidiary, nor the operations conducted thereon violate any Environmental Laws;

     (b) without limitation of clause (a) above, no property of any Loan Party or any Subsidiary, nor the operations currently conducted thereon or, to the best knowledge of the Borrower, by any prior owner or operator of such property or operation, are in violation of or subject to any existing, pending or, to the Borrower’s knowledge, threatened action, suit, investigation, inquiry or proceeding by or before any Governmental Authority or to any remedial obligations under Environmental Laws;

All outstanding shares of stock of each class of each Restricted Subsidiary of Borrower have been and will be validly issued and are and will be fully paid and nonassessable. Except as otherwise set forth on Schedule 5.13, all outstanding shares of stock of each class of each Restricted Subsidiary of Borrower are and will be owned, beneficially and of record, by Borrower or a wholly-owned Subsidiary of Borrower. All outstanding shares of stock of each class of (i) Bois d’Arc Energy owned by the Borrower or any Restricted Subsidiary and (ii) each Restricted Subsidiary of Borrower, are and will be free and clear of any Liens (other than Liens permitted by Section 7.1).

ARTICLE IX.
ADMINISTRATIVE AGENT

     SECTION 9.1 Appointment and Authorization of Administrative Agent.

     (a) Each Lender hereby irrevocably (subject to Section 9.9) appoints, designates and authorizes the Administrative Agent to take such action on its behalf under the provisions of this Agreement and each other Loan Document and to exercise such powers and perform such duties as are expressly delegated to it by the terms of this Agreement or any other Loan Document, together with such powers as are reasonably incidental thereto. Notwithstanding any provision to the contrary contained elsewhere herein or in any other Loan Document, the Administrative Agent shall not have any duties or responsibilities, except those expressly set forth herein, nor

shall the Administrative Agent have or be deemed to have any fiduciary relationship with any Lender or participant, and no implied covenants, functions, responsibilities, duties, obligations or liabilities shall be read into this Agreement or any other Loan Document or otherwise exist against the Administrative Agent. Without limiting the generality of the foregoing sentence, the use of the term “agent” herein and in the other Loan Documents with reference to the Administrative Agent is not intended to connote any fiduciary or other implied (or express) obligations arising under agency doctrine of any applicable law. Instead, such term is used merely as a matter of market custom, and is intended to create or reflect only an administrative relationship between independent contracting parties. Each Lender hereby agrees to assert no claim against the Administrative Agent on any agency theory or any other theory of liability for breach of fiduciary duty, all of which claims are hereby expressly waived by each Lender.

     (b) The Issuing Bank shall act on behalf of the Lenders with respect to any Letters of Credit issued by it and the documents associated therewith until such time (and except for so long) as the Administrative Agent may agree at the request of the Majority Lenders to act for the Issuing Bank with respect thereto; provided, however, that the Issuing Bank shall have all of the benefits and immunities (i) provided to the Administrative Agent in this Article IX with respect to any acts taken or omissions suffered by the Issuing Bank in connection with Letters of Credit issued by it or proposed to be issued by it and the application and agreements for letters of credit pertaining to the Letters of Credit as fully as if the term “Administrative Agent” as used in this Article IX included the Issuing Bank with respect to such acts or omissions, and (ii) as additionally provided herein with respect to the Issuing Bank.

     SECTION 9.2 Delegation of Duties. The Administrative Agent may execute any of its duties under this Agreement or any other Loan Document by or through agents, employees or attorneys-in-fact and shall be entitled to advice of counsel and other consultants or experts concerning all matters pertaining to such duties. The Administrative Agent shall not be responsible for the negligence or misconduct of any agent or attorney-in-fact that it selects in the absence of gross negligence or willful misconduct.

     SECTION 9.3 Liability of Administrative Agent. No Agent-Related Person shall (a) be liable for any action taken or omitted to be taken by any of them under or in connection with this Agreement or any other Loan Document or the transactions contemplated hereby (except for its own gross negligence or willful misconduct in connection with its duties expressly set forth herein), or (b) be responsible in any manner to any Lender or participant for any recital, preliminary statement, statement, representation or warranty made by any Loan Party or any officer thereof, contained herein or in any other Loan Document, or in any certificate, report, statement or other document referred to or provided for in, or received by the Administrative Agent under or in connection with, this Agreement or any other Loan Document, or the validity, effectiveness, genuineness, enforceability or sufficiency of this Agreement or any other Loan Document, or for any failure of any Loan Party or any other party to any Loan Document to perform its obligations hereunder or thereunder. No Agent-Related Person shall be under any obligation to any Lender or participant to ascertain or to inquire as to the observance or performance of any of the agreements contained in, or conditions of, this Agreement or any other Loan Document, or to inspect the properties, books or records of any Loan Party or any Affiliate thereof.

     SECTION 9.4 Reliance by Administrative Agent.

     (a) The Administrative Agent shall be entitled to rely, and shall be fully protected in relying, upon any writing, communication, signature, resolution, representation, notice, consent, certificate, affidavit, letter, telegram, facsimile, telex or telephone message, statement or other document or conversation believed by it to be genuine and correct and to have been signed, sent or made by the proper Person or Persons, and upon advice and statements of legal counsel (including counsel to any Loan Party), independent accountants and other experts selected by the Administrative Agent. The Administrative Agent shall be fully justified in failing or refusing to take any action under any Loan Document unless it shall first receive such advice or concurrence of the Majority Lenders as it deems appropriate and, if it so requests, it shall first be indemnified to its satisfaction by the Lenders against any and all liability and expense which may be incurred by it by reason of taking or continuing to take any such action. The Administrative Agent shall in all cases be fully protected in acting, or in refraining from acting, under this Agreement or any other Loan Document in accordance with a request or consent of the Majority Lenders or all the Lenders, if required hereunder, and such request and any action taken or failure to act pursuant thereto shall be binding upon all the Lenders and participants. Where this Agreement expressly permits or prohibits an action unless the Majority Lenders otherwise determine, the Administrative Agent shall, and in all other instances, the Administrative Agent may, but shall not be required to, initiate any solicitation for the consent or a vote of the Lenders.

     (b) For purposes of determining compliance with the conditions specified in Section 4.1, each Lender that has signed this Agreement shall be deemed to have consented to, approved or accepted or to be satisfied with, each document or other matter either sent by the Administrative Agent to such Lender for consent, approval, acceptance or satisfaction, or required thereunder to be consented to or approved by or acceptable or satisfactory to a Lender.

     SECTION 9.5 Notice of Default. The Administrative Agent shall not be deemed to have knowledge or notice of the occurrence of any Default or Event of Default, except with respect to defaults in the payment of principal, interest and fees required to be paid to the Administrative Agent for the account of the Lenders, unless the Administrative Agent shall have received written notice from a Lender or the Borrower referring to this Agreement, describing such Default or Event of Default and stating that such notice is a “notice of default.” The Administrative Agent will notify the Lenders of its receipt of any such notice. The Administrative Agent shall take such action with respect to such Default or Event of Default as may be directed by the Majority Lenders in accordance with Article VIII; provided, however, that unless and until the Administrative Agent has received any such direction, the Administrative Agent may (but shall not be obligated to) take such action, or refrain from taking such action, with respect to such Default or Event of Default as it shall deem advisable or in the best interest of the Lenders.

     SECTION 9.6 Credit Decision; Disclosure of Information by Administrative Agent. Each Lender acknowledges that no Agent-Related Person has made any representation or warranty to it, and that no act by the Administrative Agent hereinafter taken, including any consent to and acceptance of any assignment or review of the affairs of any Loan Party or any Affiliate thereof, shall be deemed to constitute any representation or warranty by any Agent-

Related Person to any Lender as to any matter, including whether Agent-Related Persons have disclosed material information in their possession. Each Lender represents to the Administrative Agent that it has, independently and without reliance upon any Agent-Related Person and based on such documents and information as it has deemed appropriate, made its own appraisal of and investigation into the business, prospects, operations, property, financial and other condition and creditworthiness of the Loan Parties and their respective Restricted Subsidiaries, and all applicable bank or other regulatory Laws relating to the transactions contemplated hereby, and made its own decision to enter into this Agreement and to extend credit to the Borrower hereunder. Each Lender also represents that it will, independently and without reliance upon any Agent-Related Person and based on such documents and information as it shall deem appropriate at the time, continue to make its own credit analysis, appraisals and decisions in taking or not taking action under this Agreement and the other Loan Documents, and to make such investigations as it deems necessary to inform itself as to the business, prospects, operations, property, financial and other condition and creditworthiness of the Borrower and the other Loan Parties. Except for notices, reports and other documents expressly required to be furnished to the Lenders by the Administrative Agent herein, the Administrative Agent shall not have any duty or responsibility to provide any Lender with any credit or other information concerning the business, prospects, operations, property, financial and other condition or creditworthiness of any of the Loan Parties or any of their respective Affiliates which may come into the possession of any Agent-Related Person.

     SECTION 9.7 Indemnification of Administrative Agent. Whether or not the transactions contemplated hereby are consummated, the Lenders shall indemnify upon demand each Agent-Related Person (to the extent not reimbursed by or on behalf of any Loan Party and without limiting the obligation of any Loan Party to do so), pro rata, and hold harmless each Agent-Related Person from and against any and all Indemnified Liabilities incurred by it (INCLUDING ANY AND ALL INDEMNIFIED LIABILITIES ARISING OUT OF, IN ANY WAY RELATING TO, OR RESULTING FROM SUCH AGENT-RELATED PARTY’S OWN NEGLIGENCE); provided, however, that no Lender shall be liable for the payment to any Agent-Related Person of any portion of such Indemnified Liabilities resulting from such Agent-Related Person’s gross negligence or willful misconduct; provided, however, that no action taken in accordance with the directions of the Majority Lenders shall be deemed to constitute gross negligence or willful misconduct for purposes of this Section. Without limitation of the foregoing, each Lender shall reimburse the Administrative Agent upon demand for its ratable share of any costs or out-of-pocket expenses (including Attorney Costs) incurred by the Administrative Agent 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, any other Loan Document, or any document contemplated by or referred to herein, to the extent that the Administrative Agent is not reimbursed for such expenses by or on behalf of the Borrower. The undertaking in this Section shall survive termination of the Commitments, the payment of all Obligations hereunder and the resignation or replacement of the Administrative Agent.

     SECTION 9.8 Administrative Agent in its Individual Capacity. BMO and its Affiliates may make loans to, issue letters of credit for the account of, accept deposits from,

acquire equity interests in and generally engage in any kind of banking, trust, financial advisory, underwriting or other business with each of the Loan Parties and their respective Affiliates as though BMO were not the Administrative Agent or the Issuing Bank hereunder and without notice to or consent of the Lenders. The Lenders acknowledge that, pursuant to such activities, BMO or its Affiliates may receive information regarding any Loan Party or its Affiliates (including information that may be subject to confidentiality obligations in favor of such Loan Party or such Affiliate) and acknowledge that the Administrative Agent shall be under no obligation to provide such information to them. With respect to its Loans, BMO shall have the same rights and powers under this Agreement as any other Lender and may exercise such rights and powers as though it were not the Administrative Agent or the Issuing Bank, and the terms “Lender” and “Lenders” include BMO in its individual capacity.

     SECTION 9.9 Successor Administrative Agent. The Administrative Agent may resign as Administrative Agent upon 30 days’ notice to the Lenders. If the Administrative Agent resigns under this Agreement, the Majority Lenders shall appoint from among the Lenders a successor administrative agent for the Lenders. If no successor administrative agent is appointed prior to the effective date of the resignation of the Administrative Agent, the Administrative Agent may appoint, after consulting with the Lenders, a successor administrative agent from among the Lenders. Upon the acceptance of its appointment as successor administrative agent hereunder, such successor administrative agent shall succeed to all the rights, powers and duties of the retiring Administrative Agent and the term “Administrative Agent” shall mean such successor administrative agent and the retiring Administrative Agent’s appointment, powers and duties as Administrative Agent shall be terminated. After any retiring Administrative Agent’s resignation hereunder as Administrative Agent, the provisions of this Article IX and Sections 10.4 and 10.5 shall inure to its benefit as to any actions taken or omitted to be taken by it while it was Administrative Agent under this Agreement. If no successor administrative agent has accepted appointment as Administrative Agent by the date which is 30 days following a retiring Administrative Agent’s notice of resignation, the retiring Administrative Agent’s resignation shall nevertheless thereupon become effective and the Lenders shall perform all of the duties of the Administrative Agent hereunder until such time, if any, as the Majority Lenders appoint a successor agent as provided for above.

     SECTION 9.10 Other Agents; Lead Managers. None of the Lenders identified on the facing page or signature pages of this Agreement as a “syndication agent,” “documentation agent,” “co-agent” or “lead manager” shall have any right, power, obligation, liability, responsibility or duty under this Agreement other than those applicable to all Lenders as such. Without limiting the foregoing, none of the Lenders so identified shall have or be deemed to have any fiduciary relationship with any Lender. Each Lender acknowledges that it has not relied, and will not rely, on any of the Lenders so identified in deciding to enter into this Agreement or in taking or not taking action hereunder.

     SECTION 9.11 Hedging Arrangements. To the extent any Affiliate of a Lender is a party to a Hedging Agreement with any Loan Party, such Affiliate of a Lender shall be deemed to appoint the Administrative Agent its nominee and agent, and to act for and on behalf of such Affiliate in connection with the Security Documents and to be bound by this Article IX.

     SECTION 10.3 No Waiver; Cumulative Remedies. No failure by any Lender or the Administrative Agent to exercise, and no delay by any such Person in exercising, any right, remedy, power or privilege hereunder shall operate as a waiver thereof; nor shall any single or partial exercise of any right, remedy, power or privilege hereunder preclude any other or further exercise thereof or the exercise of any other right, remedy, power or privilege.

proceeding under any Debtor Relief Law or otherwise, then (a) to the extent of such recovery, the obligation or part thereof originally intended to be satisfied shall be revived and continued in full force and effect as if such payment had not been made or such set-off had not occurred, and (b) each Lender severally agrees to pay to the Administrative Agent upon demand its applicable share of any amount so recovered from or repaid by the Administrative Agent, plus interest thereon from the date of such demand to the date such payment is made at a rate per annum equal to (i) with respect to the first two Business Days following such demand, the Federal Funds Rate from time to time in effect, and (ii) with respect to each day thereafter, the Base Rate from time to time in effect.

     SECTION 10.7 Successors and Assigns; Assignments; Participations.

     10.7.1 Successors and Assigns. The provisions of this Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns permitted hereby, except that the Borrower may not assign or otherwise transfer any of its rights or obligations hereunder without the prior written consent of each Lender (and any attempted assignment or transfer by the Borrower without such consent shall be null and void). Nothing in this Agreement, expressed or implied, shall be construed to confer upon any Person (other than the parties hereto, their respective successors and assigns permitted hereby and, to the extent expressly contemplated hereby, the Indemnitees) any legal or equitable right, remedy or claim under or by reason of this Agreement.

     10.7.2 Assignments.

     (a) Any Lender may assign to one or more Eligible Assignees all or a portion of its rights and obligations under this Agreement (including all or a portion of its Commitment and the Loans (including in all instances for purposes of this subsection (a), participations in L/C Obligations) at the time owing to it); provided that (i) except in the case of an assignment of the entire remaining amount of the assigning Lender’s Commitment and the Loans at the time owing to it or in the case of an assignment to a Lender or an Affiliate of a Lender, the aggregate amount of the Commitment (which for this purpose includes Loans outstanding thereunder, including as noted above, participations in L/C Obligations) subject to each such assignment, determined as of the date the Lender Assignment with respect to such assignment is delivered to the Administrative Agent, shall not be less than $5,000,000 unless each of the Administrative Agent and, so long as no Default has occurred and is continuing and so long as in the case of Bank of Montreal, such Lender shall have been reduced to its “final hold amount” as described in the commitment letter referred to in the Agent and Arranger Fee Letter, the Borrower otherwise consents (each such consent not to be unreasonably withheld or delayed), (ii) each partial assignment shall be made as an assignment of a proportionate part of all the assigning Lender’s rights and obligations under this Agreement with respect to the Loans or the Commitment assigned, except that this clause (ii) shall not prohibit any Lender from assigning all or a portion of its rights and obligations among separate Borrowings on a non-pro rata basis, (iii) the parties to each assignment shall execute and deliver to the Administrative Agent a Lender Assignment, together with a processing and recordation fee of $3,500. Subject to acceptance and recording thereof by the Administrative Agent pursuant to subsection (c) of this Section, from and after the effective date specified in each Lender Assignment, the Eligible

Assignee thereunder shall be a party hereto and, to the extent of the interest assigned by such Lender Assignment, have the rights and obligations of a Lender under this Agreement, and the assigning Lender thereunder shall, to the extent of the interest assigned by such Lender Assignment, be released from its obligations under this Agreement (and, in the case of an Lender Assignment covering all of the assigning Lender’s rights and obligations under this Agreement, such Lender shall cease to be a party hereto but shall continue to be entitled to the benefits of Sections 3.7, 10.4 and 10.5). Upon request, the Borrower (at its expense) shall execute and deliver new or replacement Notes to the assigning Lender and the assignee Lender. Any assignment or transfer by a Lender of rights or obligations under this Agreement that does not comply with this subsection shall be treated for purposes of this Agreement as a sale by such Lender of a participation in such rights and obligations in accordance with Section 10.7.3 of this Section.

     (b) The Administrative Agent, acting solely for this purpose as an agent of the Borrower, shall maintain at the Administrative Agent’s Office a copy of each Lender Assignment delivered to it and a register for the recordation of the names and addresses of the Lenders, and the Commitments of, and principal amount of the Loans and L/C Obligations owing to, each Lender pursuant to the terms hereof from time to time (the “Register”). The entries in the Register shall be conclusive, and the Borrower, the Administrative Agent and the Lenders may treat each Person whose name is recorded in the Register pursuant to the terms hereof as a Lender hereunder for all purposes of this Agreement, notwithstanding notice to the contrary. The Register shall be available for inspection by the Borrower and any Lender, at any reasonable time and from time to time upon reasonable prior notice.

     10.7.3 Participations.

     (a) Any Lender may, without the consent of, or notice to, the Borrower or the Administrative Agent, sell participations to one or more banks or other entities (a “Participant”) in all or a portion of such Lender’s rights and/or obligations under this Agreement (including all or a portion of its Commitment and/or the Loans (including such Lender’s participations in L/C Obligations) owing to it); provided that (i) such Lender’s obligations under this Agreement shall remain unchanged, (ii) such Lender shall remain solely responsible to the other parties hereto for the performance of such obligations and (iii) the Borrower, the Administrative Agent and the other Lenders shall continue to deal solely and directly with such Lender in connection with such Lender’s rights and obligations under this Agreement. Any agreement or instrument pursuant to which a Lender sells such a participation shall provide that such Lender shall retain the sole right to enforce this Agreement and to approve any amendment, modification or waiver of any provision of this Agreement; provided that such agreement or instrument may provide that such Lender will not, without the consent of the Participant, agree to any amendment, waiver or other modification that would (i) postpone any date upon which any payment of money is scheduled to be paid to such Participant, (ii) reduce the principal, interest, fees or other amounts payable to such Participant, or (iii) release any Guarantor from the Guaranty. Subject to subsection (b) of this Section, the Borrower agrees that each Participant shall be entitled to the benefits of Sections 3.1, 3.4 and 3.5 to the same extent as if it were a Lender and had acquired its interest by assignment pursuant to Section 10.7.2 of this Section. To the extent permitted by law,

each Participant also shall be entitled to the benefits of Section 10.9 as though it were a Lender, provided such Participant agrees to be subject to Section 2.14 as though it were a Lender.

     (b) A Participant shall not be entitled to receive any greater payment under Section 3.1 or 3.4 than the applicable Lender would have been entitled to receive with respect to the participation sold to such Participant, unless the sale of the participation to such Participant is made with the Borrower’s prior written consent. A Participant that would be a Foreign Lender if it were a Lender shall not be entitled to the benefits of Section 3.1 unless the Borrower is notified of the participation sold to such Participant and such Participant agrees, for the benefit of the Borrower, to comply with Section 3.8 as though it were a Lender.

     10.7.4 Pledge of Lender’s Interest. Any Lender may at any time pledge or assign a security interest in all or any portion of its rights under this Agreement (including under its Notes, if any) to secure obligations of such Lender, including any pledge or assignment to secure obligations to a Federal Reserve Bank; provided that no such pledge or assignment shall release a Lender from any of its obligations hereunder or substitute any such pledgee or assignee for such Lender as a party hereto.

     10.7.5 Consent to Assignment. If the consent of the Borrower to an assignment or to an Eligible Assignee is required hereunder (including a consent to an assignment which does not meet the minimum assignment threshold specified in clause (i) of the proviso to the first sentence of Section 10.7.2, the Borrower shall be deemed to have given its consent five Business Days after the date notice thereof has been delivered by the assigning Lender (through the Administrative Agent) unless such consent is expressly refused by the Borrower prior to such fifth Business Day.

“Eligible Assignee” means (a) a Lender; (b) an Affiliate of a Lender; and (c) any other Person (other than a natural Person) approved by the Administrative Agent, the Issuing Bank, and provided that no Default has occurred and is continuing, the Borrower (each such approval not to be unreasonably withheld or delayed).

     10.7.7 Assignment by BMO. Notwithstanding anything to the contrary contained herein, if at any time BMO assigns all of its Commitment and Loans pursuant to Section 10.7.2 above, BMO may, upon 30 days’ notice to the Borrower and the Lenders, resign as Issuing Bank. In the event of any such resignation as Issuing Bank, the Borrower shall be entitled to appoint from among the Lenders a successor Issuing Bank hereunder; provided, however, that no failure by the Borrower to appoint any such successor shall affect the resignation of BMO as Issuing Bank.

BMO shall retain all the rights and obligations of the Issuing Bank hereunder with respect to all Letters of Credit outstanding as of the effective date of its resignation as Issuing Bank and all L/C Obligations with respect thereto (including the right to require the Lenders to make Base Rate Loans or fund participations in Unreimbursed Amounts pursuant to Section 2.3.3).

     SECTION 10.8 Confidentiality. (a) Each of the Administrative Agent and the Lenders agrees to maintain the confidentiality of the Information (as defined below), except that Information may be disclosed (a) to its and its Affiliates’ directors, officers, employees and agents, including accountants, legal counsel and other advisors (it being understood that the Persons to whom such disclosure is made will be informed of the confidential nature of such Information and instructed to keep such Information confidential); (b) to the extent requested by any regulatory authority; (c) to the extent required by applicable laws or regulations or by any subpoena or similar legal process; (d) to any other party to this Agreement; (e) in connection with the exercise of any remedies hereunder or any suit, action or proceeding relating to this Agreement or the enforcement of rights hereunder; (f) subject to an agreement containing provisions substantially the same as those of this Section, to (i) any Eligible Assignee of or Participant in, or any prospective Eligible Assignee of or Participant in, any of its rights or obligations under this Agreement or (ii) any direct or indirect contractual counterparty or prospective counterparty (or such contractual counterparty’s or prospective counterparty’s professional advisor) to any credit derivative transaction relating to obligations of the Borrower; (g) with the consent of the Borrower; (h) to the extent such Information (i) becomes publicly available other than as a result of a breach of this Section or (ii) becomes available to the Administrative Agent or any Lender on a nonconfidential basis from a source other than the Borrower; or (i) to the National Association of Insurance Commissioners or any other similar organization or any nationally recognized rating agency that requires access to information about a Lender’s or its Affiliates’ investment portfolio in connection with ratings issued with respect to such Lender or its Affiliates. For the purposes of this Section, “Information” means all information received from the Borrower relating to the Borrower or its business, other than any such information that is available to the Administrative Agent or any Lender on a nonconfidential basis prior to disclosure by the Borrower; provided that, in the case of information received from the Borrower after the date hereof, such information is clearly identified in writing at the time of delivery as confidential. Any Person required to maintain the confidentiality of Information as provided in this Section shall be considered to have complied with its obligation to do so if such Person has exercised the same degree of care to maintain the confidentiality of such Information as such Person would accord to its own confidential information.

     SECTION 10.9 Set-off. In addition to any rights and remedies of the Lenders provided by law, upon the occurrence and during the continuance of any Event of Default, each Lender is authorized at any time and from time to time, without prior notice to the Borrower or any other Loan Party, any such notice being waived by the Borrower (on its own behalf and on behalf of each Loan Party) to the fullest extent permitted by law, to set off and apply any and all deposits (general or special, time or demand, provisional or final) at any time held by, and other indebtedness at any time owing by, such Lender to or for the credit or the account of the respective Loan Parties against any and all Obligations owing to such Lender, now or hereafter existing, irrespective of whether or not the Administrative Agent or such Lender shall have made

demand under this Agreement or any other Loan Document and although such Obligations may be contingent or unmatured. Each Lender agrees promptly to notify the Borrower and the Administrative Agent after any such set-off and application made by such Lender; provided, however, that the failure to give such notice shall not affect the validity of such set-off and application.

     SECTION 10.10 Interest Rate Limitation. It is the intention of the parties hereto to conform strictly to applicable usury laws and, anything herein to the contrary notwithstanding, the obligations of the Borrower to each Lender and the Issuing Bank under this Agreement shall be subject to the limitation that payments of interest shall not be required to the extent that receipt thereof would be contrary to provisions of law applicable to such Lender or the Issuing Bank limiting rates of interest which may be charged or collected by such Lender or the Issuing Bank. Accordingly, if the transactions contemplated hereby would be usurious under applicable law (including the Federal and state laws of the United States of America, or of any other jurisdiction whose laws may be mandatorily applicable) with respect to a Lender or the Issuing Bank then, in that event, notwithstanding anything to the contrary in this Agreement, it is agreed as follows: (i) the provisions of this Section 10.10 shall govern and control; (ii) the aggregate of all consideration which constitutes interest under applicable law that is contracted for, charged or received under this Agreement, or under any of the other aforesaid agreements or otherwise in connection with this Agreement by such Lender or the Issuing Bank shall under no circumstances exceed the maximum amount of interest allowed by applicable law (such maximum lawful interest rate, if any, with respect to such Lender or the Issuing Bank herein called the “Highest Lawful Rate”), and any excess shall be credited to the Borrower by such Lender or the Issuing Bank (or, if such consideration shall have been paid in full, such excess promptly refunded to the Borrower); (iii) all sums paid, or agreed to be paid, to the Lender or the Issuing Bank for the use, forbearance and detention of the indebtedness of the Borrower to such Lender or the Issuing Bank hereunder shall, to the extent permitted by applicable law, be amortized, prorated, allocated and spread throughout the full term of such indebtedness until payment in full so that the actual rate of interest is uniform throughout the full term thereof; and (iv) if at any time the interest provided pursuant to Article II together with any other fees payable pursuant to this Agreement and deemed interest under applicable law, exceeds that amount which would have accrued at the Highest Lawful Rate, the amount of interest and any such fees to accrue to such Lender or the Issuing Bank pursuant to this Agreement shall be limited, notwithstanding anything to the contrary in this Agreement to that amount which would have accrued at the Highest Lawful Rate, but any subsequent reductions, as applicable, shall not reduce the interest to accrue to such Lender or the Issuing Bank pursuant to this Agreement below the Highest Lawful Rate until the total amount of interest accrued pursuant to this Agreement and such fees deemed to be interest equals the amount of interest which would have accrued to such Lender or the Issuing Bank if a varying rate per annum equal to the interest provided pursuant to Article II had at all times been in effect, plus the amount of fees which would have been received but for the effect of this Section 10.10. For purposes of Tex. Fin. Code Ann. Ch. 303, as amended, to the extent, if any, applicable to a Lender or the Issuing Bank, the Borrower agrees that the Highest Lawful Rate shall be the “weekly ceiling” as defined in said Article, provided that such Lender and the Issuing Bank may also rely, to the extent permitted by applicable laws, on alternative maximum rates of interest under other laws applicable to such Lender or such Issuer, as the case may be, if greater. Tex. Fin. Code Ann. Ch. 346 (which

regulates certain revolving credit loan accounts and revolving tri-party accounts) shall not apply to this Agreement or the Notes.

     SECTION 10.11 Counterparts. This Agreement may be executed in one or more counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument.

     SECTION 10.12 Survival of Representations and Warranties. All representations and warranties made hereunder and in any other Loan Document or other document delivered pursuant hereto or thereto or in connection herewith or therewith shall survive the execution and delivery hereof and thereof. Such representations and warranties have been or will be relied upon by the Administrative Agent and each Lender, regardless of any investigation made by the Administrative Agent or any Lender or on their behalf and notwithstanding that the Administrative Agent or any Lender may have had notice or knowledge of any Default or Event of Default at the time of any Credit Extension, and shall continue in full force and effect as long as any Loan or any other Obligation shall remain unpaid or unsatisfied or any Letter of Credit shall remain outstanding.

     SECTION 10.13 Collateral Matters; Hedges. The benefit of the Security Documents and the provisions of this Agreement and the other Loan Documents relating to the collateral shall also extend to and be available on a pro rata basis to each Lender and such Lender’s Affiliates in respect of any obligations under a Hedging Agreement only so long as such Lender remains a party to this Agreement and this Agreement remains in effect. No Lender or Affiliate of a Lender shall have any voting or consent right under any Loan Document as a result of the existence of obligations owed to it under a Hedging Agreement.

     SECTION 10.14 Renewal and Continuation of Prior Indebtedness. Upon the effectiveness of this Agreement, all of the Prior Indebtedness outstanding on such date shall hereby be restructured, rearranged, renewed, extended and continued as provided in this Agreement and all Loans outstanding under the Prior Credit Facility shall become Loans outstanding hereunder.

     In connection herewith, the Prior Lenders have sold, assigned, transferred and conveyed, and Lenders party to this Agreement have purchased and accepted, and hereby purchase and accept, so much of the Prior Indebtedness such that each Lender’s percentage of the loans and obligations outstanding pursuant to the Prior Credit Facility, as restructured, rearranged, renewed, extended and continued pursuant to this Agreement, shall be equal to such Lender’s Percentage Share upon the effectiveness of this Agreement. The Lenders acknowledge and agree that the assignment, transfer and conveyance of the Prior Indebtedness is without recourse to the Prior Lenders and without any warranties whatsoever by any Prior Lender.

     SECTION 10.15 Severability. Any provision of this Agreement and the other Loan Documents to which the Borrower is a party that is prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions thereof, and any such prohibition or unenforceability in any jurisdiction shall not invalidate or render unenforceable such provision in any other jurisdiction.

     SECTION 10.16 Authorization to Release Subordinate Mortgages. By executing this Agreement, each Lender hereby consents to the execution by the Administrative Agent and delivery to the Borrower or its designee one or more releases of any subordinate mortgages, deeds of trust, assignments, security agreements, financing statements and fixture filings heretofore delivered by a Guarantor in favor of the Borrower to secure any Indebtedness of such Guarantor owing to the Borrower that have been collaterally assigned to the Administrative Agent for the benefit of the Lenders and the other parties secured thereby (including, without limitation, the Subordinate Mortgages), together with any and all other documents or instruments of release with respect to the Liens evidenced thereby as the Administrative Agent shall determine are necessary or appropriate (in its sole discretion).

     SECTION 10.17 USA PATRIOT Act Notice. Each Lender that is subject to the Act (as hereinafter defined) and the Administrative Agent (for itself and not on behalf of any Lender) hereby notifies the Borrower and each other Loan Party 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 and each other Loan Party, which information includes the name and address of the Borrower and each other Loan Party and other information that will allow such Lender or the Administrative Agent, as applicable, to identify the Borrower and each other Loan Party in accordance with the Act.

     SECTION 10.18 Governing Law.

     (a) THIS AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAW OF THE STATE OF NEW YORK APPLICABLE TO AGREEMENTS MADE AND TO BE PERFORMED ENTIRELY WITHIN SUCH STATE (WITHOUT GIVING EFFECT TO THE PRINCIPLES THEREOF RELATING TO CONFLICT OF LAW EXCEPT SECTION 5-1401 OF THE NEW YORK GENERAL OBLIGATIONS LAW); PROVIDED THAT THE ADMINISTRATIVE AGENT AND EACH LENDER SHALL RETAIN ALL RIGHTS ARISING UNDER FEDERAL LAW.

     (b) ANY LEGAL ACTION OR PROCEEDING WITH RESPECT TO THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT MAY BE BROUGHT IN THE COURTS OF THE STATE OF NEW YORK SITTING IN MANHATTAN OR OF THE UNITED STATES FOR THE SOUTHERN DISTRICT OF SUCH STATE, AND BY EXECUTION AND DELIVERY OF THIS AGREEMENT, THE BORROWER, THE ADMINISTRATIVE AGENT AND EACH LENDER CONSENTS, FOR ITSELF AND IN RESPECT OF ITS PROPERTY, TO THE NON-EXCLUSIVE JURISDICTION OF THOSE COURTS. THE BORROWER, THE ADMINISTRATIVE AGENT AND EACH LENDER IRREVOCABLY WAIVES ANY OBJECTION, INCLUDING ANY OBJECTION TO THE LAYING OF VENUE OR BASED ON THE GROUNDS OF FORUM NON CONVENIENS, WHICH IT MAY NOW OR HEREAFTER HAVE TO THE BRINGING OF ANY ACTION OR PROCEEDING IN SUCH JURISDICTION IN RESPECT OF ANY LOAN DOCUMENT OR OTHER DOCUMENT RELATED THERETO. THE BORROWER, THE ADMINISTRATIVE AGENT AND EACH LENDER WAIVES PERSONAL SERVICE OF ANY SUMMONS, COMPLAINT OR OTHER PROCESS, WHICH MAY BE MADE BY ANY OTHER MEANS PERMITTED BY THE LAW OF SUCH STATE.

     SECTION 10.19 Waiver of Right to Trial by Jury. EACH PARTY TO THIS AGREEMENT HEREBY EXPRESSLY WAIVES ANY RIGHT TO TRIAL BY JURY OF ANY CLAIM, DEMAND, ACTION OR CAUSE OF ACTION ARISING UNDER ANY LOAN DOCUMENT OR IN ANY WAY CONNECTED WITH OR RELATED OR INCIDENTAL TO THE DEALINGS OF THE PARTIES HERETO OR ANY OF THEM WITH RESPECT TO ANY LOAN DOCUMENT, OR THE TRANSACTIONS RELATED THERETO, IN EACH CASE WHETHER NOW EXISTING OR HEREAFTER ARISING, AND WHETHER FOUNDED IN CONTRACT OR TORT OR OTHERWISE; AND EACH PARTY HEREBY AGREES AND CONSENTS THAT ANY SUCH CLAIM, DEMAND, ACTION OR CAUSE OF ACTION SHALL BE DECIDED BY COURT TRIAL WITHOUT A JURY, AND THAT ANY PARTY TO THIS AGREEMENT MAY FILE AN ORIGINAL COUNTERPART OR A COPY OF THIS SECTION WITH ANY COURT AS WRITTEN EVIDENCE OF THE CONSENT OF THE SIGNATORIES HERETO TO THE WAIVER OF THEIR RIGHT TO TRIAL BY JURY.

     SECTION 10.20 Consents to Renewals, Modifications and Other Actions and Events. This Agreement and all of the obligations of the Borrower hereunder shall remain in full force and effect without regard to and shall not be released, affected or impaired by: (a) any amendment, assignment, transfer, modification of or addition or supplement to the Lenders’ Obligations, this Agreement, any Note or any other Loan Document; (b) any extension, indulgence, increase in the Lenders’ Obligations or other action or inaction in respect of any of the Loan Documents or otherwise with respect to the Lenders’ Obligations, or any acceptance of security for, or guaranties of, any of the Lenders’ Obligations or Loan Documents, or any surrender, release, exchange, impairment or alteration of any such security or guaranties including without limitation the failing to perfect a security interest in any such security or abstaining from taking advantage or of realizing upon any guaranties or upon any security interest in any such security; (c) any default by the Borrower under, or any lack of due execution, invalidity or unenforceability of, or any irregularity or other defect in, any of the Loan Documents; (d) any waiver by the Lenders or any other Person of any required performance or otherwise of any condition precedent or waiver of any requirement imposed by any of the Loan Documents, any guaranties or otherwise with respect to the Lenders’ Obligations; (e) any exercise or non-exercise of any right, remedy, power or privilege in respect of this Agreement or any of the other Loan Documents; (f) any sale, lease, transfer or other disposition of the assets of the Borrower or any consolidation or merger of the Borrower with or into any other Person, corporation, or entity, or any transfer or other disposition by the Borrower or any other holder of any shares of capital stock or other ownership interest of the Borrower; (g) any bankruptcy, insolvency, reorganization or similar proceedings involving or affecting the Borrower; (h) the release or discharge of the Borrower from the performance or observance of any agreement, covenant, term or condition under any of the Obligations or contained in any of the Loan Documents by operation of law; or (i) any other cause whether similar or dissimilar to the foregoing which, in the absence of this provision, would release, affect or impair the Obligations, covenants, agreements and duties of the Borrower hereunder, including without limitation any act or omission by the Administrative Agent, or the Lenders or any other Person which increases the scope of the Borrower’s risk; and in each case described in this paragraph whether or not the Borrower shall have notice or knowledge of any of the foregoing, each of which is specifically waived by the Borrower. The Borrower warrants to the Administrative Agent and the Lenders

that it has adequate means to obtain from the Guarantors on a continuing basis information concerning the financial condition and other matters with respect to the Guarantors and it is not relying on the Administrative Agent or the Lenders to provide such information either now or in the future.

     SECTION 10.21 ENTIRE AGREEMENT. This Agreement, together with the other Loan Documents, comprises the complete and integrated agreement of the parties on the subject matter hereof and thereof and supersedes all prior agreements, written or oral, on such subject matter.

THERE ARE NO UNWRITTEN ORAL AGREEMENTS BETWEEN THE PARTIES.

     IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be duly executed as of the date first above written.
