Each Borrowing shall be (A) in an aggregate principal amount of $1,000,000 or any larger integral multiple of $100,000 (except that any Base Rate Borrowing may be in an amount equal to the Availability at such time), and (B) made from the Banks ratably in accordance with their respective Commitment Percentages. Subject to the foregoing limitations and the other provisions of this Agreement, prior to the Termination Date Borrower may borrow under this Section 2.1(a), repay amounts borrowed and request new Borrowings to be made under this Section 2.1(a). The Total Commitment as of the Closing Date is the Initial Total Commitment.

(b) Administrative Agent, or such Bank designated by Administrative Agent which (without obligation to do so) consents to the same (“Letter of Credit Issuer”) will, from time to time prior to the date which is five (5) Domestic Business Days prior to the Termination Date, upon request by Borrower, issue Letters of Credit for the account of Borrower or any Restricted Subsidiary designated by Borrower, so long as (i) the sum of (A) the total Letter of Credit Exposure then existing, and (B) the amount of the requested Letter of Credit does not exceed $30,000,000, and (ii) Borrower would be entitled to a Borrowing under Section 2.1(a) and Section 2.1(c) in the amount of the requested Letter of Credit. Not less than three (3) Domestic Business Days prior to the requested date of issuance of any such Letter of Credit, Borrower (and any Restricted Subsidiary for whose account such Letter of Credit is being issued) shall execute and deliver to Letter of Credit Issuer, Letter of Credit Issuer’s customary letter of credit application. Each Letter of Credit shall be in the minimum amount of $10,000 and shall be in form and substance acceptable to Letter of Credit Issuer. No Letter of Credit shall have an expiration date later than the earlier of (1) the Termination Date, or (2) one (1) year from the date of issuance (or, in the case of any renewal or extension thereof, one (1) year after such renewal or extension). Upon the date of issuance of a Letter of Credit, Letter of Credit Issuer shall be deemed to have sold to each other Bank, and each other Bank shall be deemed to have unconditionally and irrevocably purchased from Letter of Credit Issuer, a non recourse participation in the related Letter of Credit and Letter of Credit Exposure equal to such Bank’s Commitment Percentage of such Letter of Credit and Letter of Credit Exposure. Upon request of any Bank, but not less often than quarterly, Administrative Agent shall provide notice to each

Bank by telephone, teletransmission or telex setting forth each Letter of Credit issued and outstanding pursuant to the terms hereof and specifying the beneficiary and expiration date of each such Letter of Credit, each Bank’s percentage of each such Letter of Credit and the actual dollar amount of each Bank’s participation held by Letter of Credit Issuer thereof for such Bank’s account and risk. At the time of issuance of each Letter of Credit, Borrower shall pay to Administrative Agent in respect of such Letter of Credit (a) the applicable Letter of Credit Fee, and (b) the applicable Letter of Credit Fronting Fee. Administrative Agent shall distribute the Letter of Credit Fee payable upon the issuance of each Letter of Credit to Banks in accordance with their respective Commitment Percentages, and Administrative Agent shall distribute the Letter of Credit Fronting Fee to Letter of Credit Issuer for its own account. Any (y) material amendment or modification, or (z) renewal or extension of any Letter of Credit shall be deemed to be the issuance of a new Letter of Credit for purposes of this Section 2.1(b). Notwithstanding anything to the contrary contained herein, (i) Borrower shall pay to Letter of Credit Issuer in connection with the issuance of each Letter of Credit and/or any amendment or modification of any nature to any existing Letter of Credit, Letter of Credit Issuer’s usual and customary fees for the issuance of, amendments or modifications to, and processing of, Letters of Credit and (ii) the Letter of Credit Issuer shall not at any time be obligated to issue, amend, renew or extend any Letter of Credit if any Bank is at such time a Defaulting Bank hereunder, unless the Letter of Credit Issuer has entered into satisfactory arrangements with the Borrower or such Bank to eliminate Letter of Credit Issuer’s risk with respect to such Bank.

Immediately upon the occurrence of an Event of Default and the acceleration of the Obligations hereunder, and also on the date which is five (5) Domestic Business Days prior to the Termination Date, Borrower shall deposit with Administrative Agent cash in such amounts as Administrative Agent may request, up to a maximum amount equal to the aggregate existing Letter of Credit Exposure of all Banks; provided, that, in the case of any of the Events of Default specified in Section 11.1(g) or Section 11.1(h), an amount equal to the aggregate existing Letter of Credit Exposure of all Banks shall be due and payable without any notice to Borrower or any other act by Administrative Agent or any Bank. Any amounts so deposited shall be held by Administrative Agent for the ratable benefit of all Banks as security for the outstanding Letter of Credit Exposure and the other Obligations, and Borrower will, in connection therewith, execute and deliver such security agreements in form and substance satisfactory to Administrative Agent which Administrative Agent may, in its discretion, require. As drafts or demands for payment are presented under any Letter of Credit, Administrative Agent shall apply such cash to satisfy such drafts or demands. When all Letters of Credit have expired and the Obligations have been repaid in full (and no Bank has any obligation to lend or issue Letters of Credit hereunder) or such Event of Default has been cured to the satisfaction of Majority Banks, Administrative Agent shall release to Borrower any remaining cash deposited under this Section 2.1(b). Whenever Borrower is required to make deposits under this Section 2.1(b) and fails to do so on the day such deposit is due, Administrative Agent or any Bank may, without notice to Borrower, make such deposit (whether by application of proceeds of any collateral for the Obligations, by transfers from other accounts maintained with any Bank or otherwise) using any funds then available to any Bank of any Credit Party, any guarantor or any other party liable for repayment of the Obligations.

Notwithstanding anything to the contrary contained herein, Borrower hereby agrees to reimburse each Letter of Credit Issuer immediately upon demand by such Letter of Credit Issuer,

and inimmediately available funds, for any payment or disbursement made by such Letter of Credit Issuer under any Letter of Credit issued by it. Payment shall be made by Borrower with interest on the amount so paid or disbursed by Letter of Credit Issuer from and including the date payment is made under any Letter of Credit to and including the date of payment, at the lesser of (i) the Maximum Lawful Rate, or (ii) the Default Rate. The obligations of Borrower under this paragraph will continue until all Letters of Credit have expired and all reimbursement obligations with respect thereto have been paid in full by Borrower and until all other Obligations shall have been paid in full.

Borrower shall be obligated to reimburse Letter of Credit Issuer upon demand for all amounts paid under Letters of Credit as set forth in the immediately preceding paragraph hereof; provided, however, if Borrower for any reason fails to reimburse Letter of Credit Issuer in full upon demand, Banks shall reimburse Letter of Credit Issuer in accordance with each Banks’ Commitment Percentage for amounts due and unpaid from Borrower as set forth hereinbelow; provided, however, that no such reimbursement made by Banks shall discharge Borrower’s obligations to reimburse Letter of Credit Issuer. All reimbursement amounts payable by any Bank under this Section 2.1(b) shall include interest thereon at the Federal Funds Rate, from the date of the payment of such amounts by Letter of Credit Issuer to the date of reimbursement by such Bank. No Bank shall be liable for the performance or nonperformance of the obligations of any other Bank under this paragraph. The reimbursement obligations of Banks under this paragraph shall continue after the Termination Date and shall survive termination of this Agreement and the other Loan Papers.

Borrower shall indemnify and hold Administrative Agent, Letter of Credit Issuer and each Bank, and their respective officers, directors, representatives and employees harmless from loss for any claim, demand or liability which may be asserted against any or such indemnified party in connection with actions taken under Letters of Credit or in connection therewith (including losses resulting from the negligence of any or such indemnified party), and shall pay each indemnified party for reasonable fees of attorneys and legal costs paid or incurred by each indemnified party in connection with any matter related to Letters of Credit, except for losses and liabilities incurred as a direct result of the gross negligence or willful misconduct of such indemnified party, IT BEING THE EXPRESS INTENTION OF THE PARTIES THAT EACH INDEMNIFIED PARTY SHALL BE INDEMNIFIED FOR THE CONSEQUENCES OF ITS OWN ORDINARY NEGLIGENCE. If Borrower for any reason fails to indemnify or pay Administrative Agent or Letter of Credit Issuer as set forth herein in full, Banks shall indemnify and pay such indemnified party upon demand, in accordance with each Bank’s Commitment Percentage of such amounts due and unpaid from Borrower; provided, however, that, no such payment made by Banks shall discharge Borrower’s obligation to indemnify or pay such indemnified party in accordance with the terms hereof. The provisions of this paragraph shall survive the termination of this Agreement.

Neither Administrative Agent nor any other Letter of Credit Issuer makes any representation or warranty, nor assumes any responsibility with respect to the validity, legality, sufficiency or enforceability of any letter of credit application executed and delivered in connection with any Letter of Credit issued hereunder or any document relative thereto or to the collectibility thereunder. Neither Administrative Agent nor any other Letter of Credit Issuer assumes any responsibility for the financial condition of Borrower or for the performance of any

obligation of Borrower. Administrative Agent and each other Letter of Credit Issuer may use its discretion with respect to exercising or refraining from exercising any rights, or taking or refraining from taking any action which may be vested in it or which it may be entitled to take or assert with respect to any Letter of Credit or any letter of credit application. FURTHERMORE, EXCEPT AS SET FORTH HEREIN, NEITHER ADMINISTRATIVE AGENT NOR ANY OTHER LETTER OF CREDIT ISSUER SHALL BE UNDER ANY LIABILITY TO ANY BANK, WITH RESPECT TO ANYTHING ADMINISTRATIVE AGENT OR ANY SUCH LETTER OF CREDIT ISSUER MAY DO OR REFRAIN FROM DOING IN THE EXERCISE OF ITS JUDGMENT, THE SOLE LIABILITY AND RESPONSIBILITY OF ADMINISTRATIVE AGENT AND SUCH LETTER OF CREDIT ISSUER BEING TO HANDLE EACH BANK’S SHARE ON AS FAVORABLE A BASIS AS ADMINISTRATIVE AGENT OR SUCH LETTER OF CREDIT ISSUER HANDLES ITS OWN SHARE.

FURTHERMORE, NEITHER ADMINISTRATIVE AGENT, ANY LETTER OF CREDIT ISSUER, NOR ANY OF THEIR DIRECTORS, OFFICERS, OR EMPLOYEES SHALL BE LIABLE FOR ANY ACTION TAKEN OR OMITTED (WHETHER OR NOT SUCH ACTION TAKEN OR OMITTED IS EXPRESSLY SET FORTH HEREIN) UNDER OR IN CONNECTION HEREWITH OR UNDER ANY OTHER INSTRUMENT OR DOCUMENT IN CONNECTION HEREWITH, EXCEPT FOR GROSS NEGLIGENCE OR WILLFUL MISCONDUCT. Neither Administrative Agent nor any other Letter of Credit Issuer shall incur any liability to any Bank, Borrower, or any Affiliate of any Bank or Borrower, in acting upon any notice, document, order, consent, certificate, warrant or other instrument reasonably believed by Administrative Agent or such Letter of Credit Issuer to be genuine or authentic and to be signed by the proper party.

(c) No Bank will be obligated to lend to Borrower hereunder or incur Letter of Credit Exposure, and Borrower shall not be entitled to borrow hereunder or obtain Letters of Credit hereunder, in an amount which would cause (i) such Bank’s Commitment Percentage of the Outstanding Credit to exceed its Commitment Percentage of the existing Borrowing Base, or (ii) the Outstanding Credit to exceed the Borrowing Base then in effect. No Bank shall be obligated to fund Borrowings hereunder and Borrower shall not be entitled to Borrowings hereunder during the existence of a Borrowing Base Deficiency. Nothing in this Section 2.1(c) shall be deemed to limit any Bank’s obligation to reimburse any Letter of Credit Issuer with respect to its participation in Letters of Credit as a result of the drawing under any Letter of Credit pursuant to Section 2.1(b).

(d) Notwithstanding anything to the contrary set forth in Section 2.5(a) or Section 2.5(b) above, after the occurrence of an Event of Default, interest shall accrue on the outstanding principal balance of the Revolving Loan, and to the extent permitted by Law, on the past due but unpaid interest on the Revolving Loan and all other past due Obligations from the period from and including the occurrence of such Event of Default to but excluding the date the same is remedied at a rate per annum equal to the lesser of (i) the Default Rate, and (ii) the Maximum Lawful Rate.

(e) Administrative Agent shall determine each interest rate applicable to the Revolving Loan in accordance with the terms hereof. Administrative Agent shall promptly notify Borrower and Banks by telex, telecopy or cable of each rate of interest so determined, and its determination thereof shall be conclusive in the absence of manifest error.

(f) Notwithstanding the foregoing, if at any time the rate of interest calculated with reference to the Base Rate or the Eurodollar Rate hereunder (the “contract rate”) is limited to the Maximum Lawful Rate, any subsequent reductions in the contract rate shall not reduce the rate of interest on the Revolving Loan below the Maximum Lawful Rate until the total amount of interest accrued equals the amount of interest which would have accrued if the contract rate had at all times been in effect. In the event that at maturity (stated or by acceleration), or at final payment of any Revolving Loan, the total amount of interest paid or accrued on such Revolving Loan is less than the amount of interest which would have accrued if the contract rate had at all times been in effect with respect thereto, then at such time, to the extent permitted by law, Borrower shall pay to Bank that made such Revolving Loan an amount equal to the difference between (i) the lesser of the amount of interest which would have accrued if the contract rate had at all times been in effect and the amount of interest which would have accrued if the Maximum Lawful Rate had at all times been in effect, and (ii) the amount of interest actually paid on such Revolving Loan.

(g) Interest payable hereunder on each Eurodollar Loan shall be computed based on the number of actual days elapsed assuming that each calendar year consisted of 360 days. Interest payable hereunder on the Base Rate Loan shall be computed based on the actual

number of days elapsed assuming that each calendar year consisted of 365 days (or 366 days in a leap year).

Section 2.6 Mandatory Prepayments.

(a) Upon the occurrence of any Borrowing Base Deficiency, Borrower shall make the mandatory prepayments of the Revolving Loan required by Section 4.5 hereof.

(b) At any time that Borrower becomes obligated to prepay all or part of the Permitted Senior Unsecured Debt or Permitted Senior Convertible Debt, Borrower shall, prior to any repayment of the Permitted Senior Unsecured Debt and/or Permitted Senior Convertible Debt, prepay the Revolving Loans and reduce the Commitments in full.

(c) In the event and on each occasion that any Net Proceeds are received by or on behalf of any Credit Party in respect of any Prepayment Event, the Borrower shall, promptly (and in any event within five days) after such Net Proceeds are received by any Credit Party, prepay the Obligations in an aggregate amount equal to (x) in the case of a prepayment event described in clause (b) of the definition of the term “Prepayment Event”, 50% of such Net Proceeds and (y) in the case of all other Prepayment Events, 100% of such Net Proceeds. In connection with any mandatory prepayment as required under this Section 2.6(c), there shall also be a corresponding automatic reduction in the Borrowing Base, without the need for any additional Bank approval, in the amount of such required prepayment; provided, that, (i) no reduction in the Borrowing Base pursuant to this Section 2.6(c) shall reduce the Borrowing Base to an amount less than the then existing Conforming Borrowing Base and (ii) there shall be no reduction in the Borrowing Base pursuant to this Section 2.6(c) in connection with the Specified Asset Sales. For the avoidance of doubt, any reductions in the Borrowing Base arising in connection with the Specified Asset Sales are set forth in Section 4.4(b) hereof.

Section 2.7 Voluntary Prepayments. Borrower may, subject to Section 13.5 and the other provisions of this Agreement, prepay the principal of the Revolving Loan in whole or in part. Any partial prepayment shall be in a minimum amount of $1,000,000 and shall be in an integral multiple of $100,000.

Section 2.8 Voluntary Reduction of Commitments. Borrower may, by notice to Administrative Agent three (3) Domestic Business Days prior to the effective date of any such reduction, reduce the Total Commitment (and thereby reduce the Commitment of each Bank ratably) in amounts not less than $10,000,000 and in an amount which is an integral multiple of $10,000,000 or, if less, the remaining amount of the Commitments. On the effective date of any such reduction, Borrower shall, to the extent required as a result of such reduction, make a principal payment on the Revolving Loan in an amount sufficient to cause the principal balance of the Revolving Loan then outstanding to be equal to or less than the Total Commitment as thereby reduced. Notwithstanding the foregoing, Borrower shall not be permitted to voluntarily reduce the Total Commitment to an amount less than the aggregate Letter of Credit Exposure of all Banks.

Section 2.9 Termination of Commitments; Final Maturity of Revolving Loan. The Total Commitment (and the Commitment of each Bank) shall terminate, and the entire

outstanding principal balance of the Revolving Loan, all interest accrued thereon, all accrued but unpaid fees hereunder and all other outstanding Obligations shall be due and payable in full on the Termination Date.

Section 2.10 Voluntary Increase of Total Commitment. So long as no Default or Event of Default has occurred and is continuing, or will result therefrom, and so long as no Borrowing Base Deficiency exists, Borrower shall have the right to increase the Total Commitment by increasing the existing Commitments and/or obtaining additional Commitments (the amount of such increase is herein called the “Commitment Increase”), either from (a) one or more of the Banks, or (b) another financial institution; provided, that (i) Borrower shall have notified Administrative Agent (which shall promptly deliver a copy to each Bank) in writing of the amount of the Commitment Increase, (ii) Administrative Agent and Letter of Credit Issuer shall have approved any new Bank (such approval not to be unreasonably withheld), (iii) any such new Bank shall have assumed all of the rights and obligations of a “Bank” hereunder, (iv) the procedure described in Section 14.10(f) shall have been complied with, and (v) after giving effect to the Commitment Increase, the Total Commitment shall not exceed the Maximum Total Commitment Amount. Notwithstanding anything to the contrary contained herein, the Commitment of any Bank may not be increased without the prior written consent of such Bank.

Section 2.11 Application of Payments. Each repayment pursuant to Section 2.6, Section 2.7, Section 2.8, Section 2.9, and Section 4.5 shall be made together with accrued interest on the amount repaid to the date of payment, and shall be applied in accordance with Section 3.2 and the other provisions of this Agreement.

Section 2.12 Commitment Fee. On the Termination Date, on each Quarterly Date prior to the Termination Date, and, in the event the Commitments are terminated in their entirety prior to the Termination Date, on the date of such termination, Borrower shall pay to Administrative Agent, for the ratable benefit of each Bank based on each Bank’s Commitment Percentage, a commitment fee equal to the Commitment Fee Percentage in effect from day to day (applied on a per annum basis and computed on the basis of actual days elapsed and as if each calendar year consisted of 365 days (or 366 days in a leap year)) of the average daily Availability for the Fiscal Quarter (or portion thereof) ending on the date such payment is due.

Section 2.13 Agency and other Fees. Borrower shall pay to Administrative Agent and its Affiliates such other fees and amounts as Borrower shall be required to pay to Administrative Agent and its Affiliates from time to time pursuant to any separate agreement between Borrower and Administrative Agent or such Affiliates. Such fees and other amounts shall be retained by Administrative Agent and its Affiliates, and no Bank (other than JPMorgan) shall have any interest therein. Administrative Agent may disburse any fees paid to Administrative Agent and its Affiliates pursuant to this Section 2.13 in any manner Administrative Agent desires in its sole discretion.

ARTICLE III
GENERAL PROVISIONS

Section 3.1 Delivery and Endorsement of Notes. On the Closing Date, Administrative Agent shall deliver to each Bank that is requesting a Note the Note payable to

such Bank. Each Bank may endorse (and prior to any transfer of its Note shall endorse) on the schedules attached and forming a part thereof appropriate notations to evidence the date and amount of its Commitment Percentage of each Borrowing, the Interest Period applicable thereto, and the date and amount of each payment of principal made by Borrower with respect thereto; provided that the failure by any Bank to so endorse its Note shall not affect the liability of Borrower for the repayment of all amounts outstanding under such Note together with interest thereon. Each Bank is hereby irrevocably authorized by Borrower to endorse its Note and to attach to and make a part of any such Note a continuation of any such schedule as required.

Section 3.2 General Provisions as to Payments.

(a) Borrower shall make each payment of principal of, and interest on, the Revolving Loan, and all fees payable hereunder shall be paid, not later than 12:00 noon (Chicago, Illinois time) on the date when due, in Federal or other funds immediately available in Chicago, Illinois, to Administrative Agent at its address set forth on Schedule 1.1 hereto, without defense, set-off, deduction or counterclaim. Administrative Agent will promptly (and if such payment is received by Administrative Agent by 10:00 a.m. (Chicago, Illinois time), and otherwise if reasonably possible, on the same Domestic Business Day) distribute to each Bank its Commitment Percentage of each such payment received by Administrative Agent for the account of Banks. Whenever any payment of principal of, or interest on, the Base Rate Loan or of fees shall be due on a day which is not a Domestic Business Day, the date for payment thereof shall be extended to the next succeeding Domestic Business Day. Whenever any payment of principal of, or interest on, any portion of any Eurodollar Loan shall be due on a day which is not a Eurodollar Business Day, the date for payment thereof shall be extended to the next succeeding Eurodollar Business Day (subject to the provisions of the definition of Interest Period). If the date for any payment of principal is extended by operation of Law or otherwise, interest thereon shall be payable for such extended time. Borrower hereby authorizes Administrative Agent to charge from time to time against Borrower’s accounts with Administrative Agent any amount then due.

(b) Prior to the occurrence of an Event of Default, all principal payments received by Banks with respect to the Revolving Loan shall be applied first to Eurodollar Loans outstanding with Interest Periods ending on the date of such payment, then to the Base Rate Loan, and then to Eurodollar Loans next maturing until such principal payment is fully applied.

(c) After the occurrence of an Event of Default, all amounts collected or received by Administrative Agent or any Bank shall be applied first to the payment of all proper costs incurred by Administrative Agent in connection with the collection thereof (including reasonable expenses and disbursements of Administrative Agent), second to the payment of all proper costs incurred by Banks in connection with the collection thereof (including reasonable expenses and disbursements of Banks), third to the reimbursement of any advances made by Banks to effect performance of any unperformed covenants of any Credit Party under any of the Loan Papers, fourth to the payment of any unpaid fees required pursuant to Section 2.13, fifth to the payment of any unpaid fees required pursuant to Section 2.1(b) and Section 2.12, sixth, to the payment of all accrued but unpaid interest, seventh, to the payment to each Bank of its Commitment Percentage of the outstanding principal of the Revolving Loan and to satisfy all obligations and liabilities then due under Hedge Agreements with each such Bank (and/or its

Affiliates), such payments to be made pro rata to each Bank (and/or its Affiliates) owed such Obligations in proportion to all such payments owed to all Banks (and/or their Affiliates) in respect of such Obligations, and eighth to establish the deposits required in Section 2.1(b). All payments received by a Bank after the occurrence of an Event of Default for application to the principal of the Revolving Loan shall be applied by such Bank in the manner provided in Section 3.2(b).

(d) Notwithstanding anything to the contrary contained in this Agreement, if any Bank shall fail to make any payment required to be made by it hereunder, then the Administrative Agent may, in its discretion (notwithstanding any contrary provision hereof), apply any amounts thereafter received by the Administrative Agent for the account of such Bank to satisfy such Bank’s obligations hereunder until all such unsatisfied obligations are fully paid.

ARTICLE IV
BORROWING BASE AND CONFORMING BORROWING BASE

Section 4.1 Reserve Report; Proposed Borrowing Base. The aggregate amount of credit available to Borrower under this Agreement shall be limited by a Borrowing Base (herein so called) which shall be determined by Banks at the times and in accordance with the standards and procedures set forth in this Article IV. As soon as available and in any event by March 15, and August 31 of each year, commencing March 15, 2009, Borrower shall deliver to Administrative Agent and each Bank a Reserve Report prepared as of the immediately preceding December 31 and June 30, respectively. In addition to the foregoing, the Borrower shall deliver to Administrative Agent and each Bank a Reserve Report as of November 30, 2008 (to be furnished by January 1, 2009), which Reserve Report may be prepared by Borrower’s in-house staff, and shall include a detailed reconciliation from the most recently delivered Reserve Report prepared by the Approved Petroleum Engineer. Simultaneously with the delivery to Administrative Agent and each Bank of each Reserve Report, Borrower shall notify Administrative Agent and each Bank of the amount of the Borrowing Base which Borrower requests become effective on the next Redetermination Date (or such date promptly following such Redetermination Date as Majority Banks shall elect).

Section 4.2 Scheduled Redeterminations of the Borrowing Base and Conforming Borrowing Base; Procedures and Standards. Based in part on the Reserve Reports made available to Banks pursuant to Section 4.1, Banks shall redetermine the Borrowing Base and the Conforming Borrowing Base on or prior to the next Redetermination Date (or such date promptly thereafter as reasonably possible based on the engineering and other information available to Banks). Any Borrowing Base or Conforming Borrowing Base which becomes effective as a result of any Redetermination of the Borrowing Base or the Conforming Borrowing Base shall be subject to the following restrictions: (a) such Borrowing Base shall not exceed the Borrowing Base requested by Borrower pursuant to Section 4.1 or Section 4.3 (as applicable), (b) such Borrowing Base shall not exceed the Total Commitment then in effect, (c) to the extent such Borrowing Base or Conforming Borrowing Base represents an increase from the Borrowing Base or the Conforming Borrowing Base, as applicable, in effect prior

to such Redetermination, such Borrowing Base or Conforming Borrowing Base shall be approved by all Banks, and (d) to the extent such Borrowing Base or Conforming Borrowing Base represents a decrease in the Borrowing Base or the Conforming Borrowing Base, as applicable, in effect prior to such Redetermination, or a reaffirmation of such prior Borrowing Base or Conforming Borrowing Base, as applicable, such Borrowing Base or Conforming Borrowing Base shall be approved by Required Banks. Each Redetermination shall be made by Banks in their sole discretion. Without limiting such discretion, Borrower acknowledges and agrees that Banks (i) may make such assumptions regarding appropriate existing and projected pricing for Hydrocarbons as they deem appropriate in their sole discretion, (ii) may make such assumptions regarding projected rates and quantities of future production of Hydrocarbons from the Mineral Interests owned by Borrower as they deem appropriate in their sole discretion, (iii) may consider the projected cash requirements of the Credit Parties, (iv) are not required to consider any asset other than Proved Mineral Interests owned by Borrower which are subject to first and prior Liens in favor of Administrative Agent for the ratable benefit of Banks to the extent required by Section 5.1 hereof, and (v) may make such other assumptions, considerations and exclusions as Banks deem appropriate in the exercise of their sole discretion. It is further acknowledged and agreed that each Bank may consider such other credit factors as it deems appropriate in the exercise of its sole discretion and shall have no obligation in connection with any Redetermination to approve any increase from the Borrowing Base or the Conforming Borrowing Base in effect prior to such Redetermination. Promptly following any Redetermination of the Borrowing Base or the Conforming Borrowing Base, Administrative Agent shall notify Borrower of the amount of the Borrowing Base and the Conforming Borrowing Base as redetermined, which Borrowing Base and the Conforming Borrowing Base shall be effective as of the date specified in such notice, and shall remain in effect for all purposes of this Agreement until the next Redetermination. From the Closing Date until the Conforming Date, the Banks may, in their sole discretion, establish a Borrowing Base which is higher than the Borrowing Base that would otherwise be in effect if the Banks determined the Borrowing Base based on each Bank’s Conforming Credit Criteria. At the time of each Scheduled Redetermination and Special Redetermination, the Banks shall also determine what the Borrowing Base would be if they applied Conforming Credit Criteria (which result would be the Conforming Borrowing Base). If the Banks do not determine a Conforming Borrowing Base, the Borrowing Base as redetermined and/or established shall also be the Conforming Borrowing Base for purposes of this Agreement. From and after the Conforming Date, the Borrowing Base will be an amount equal to the Conforming Borrowing Base.

Section 4.3 Special Redetermination.

(a) In addition to Scheduled Redeterminations and the other Redeterminations provided for in this Article IV, Borrower and Majority Banks shall each be permitted to request a Special Redetermination of the Borrowing Base and the Conforming Borrowing Base once in each period between Scheduled Redeterminations. Any request by Majority Banks pursuant to this Section 4.3(a) shall be submitted to Administrative Agent and Borrower. Any request by Borrower pursuant to this Section 4.3(a) shall be submitted to Administrative Agent and each Bank and at the time of such request Borrower shall (i) deliver to Administrative Agent and each Bank a Reserve Report, and (ii) also notify Administrative Agent and each Bank of the Borrowing Base requested by Borrower in connection with such Special Redetermination.

(b) Except as provided in Section 4.3(c) below, any Special Redetermination shall be made by Banks in accordance with the procedures and standards set forth in Section 4.2; provided, that, no Reserve Report will be required to be delivered to Administrative Agent and

Banks in connection with any Special Redetermination requested by Majority Banks pursuant to Section 4.3(a) above.

(c) Notwithstanding anything to the contrary contained herein, if the Total Commitment is increased to $600,000,000 pursuant to a Commitment Increase prior to the first Scheduled Redetermination after the Closing Date, the Borrowing Base shall be increased to $300,000,000 contemporaneously with such Commitment Increase, which Borrowing Base shall remain in effect until the first Redetermination to occur thereafter. The Special Redetermination described in this Section 4.3(c) shall not be deemed to be one of the Special Redeterminations permitted for each of Borrower and Majority Banks between Scheduled Redeterminations.

Section 4.4 Asset Disposition Adjustment. In addition to the other Redeterminations provided for in this Article IV, (a) Required Banks shall be permitted to redetermine the Borrowing Base and the Conforming Borrowing Base in connection with, and simultaneously with, the consummation of an Asset Disposition described in the proviso of Section 9.5(c), and reduce the (i) Borrowing Base by an amount equal to the Borrowing Base value of the Borrowing Base Properties which are the subject of such Asset Disposition (which shall be the Borrowing Base value assigned thereto by Administrative Agent and approved by Required Banks) and (ii) Conforming Borrowing Base by an amount so that the ratio of the as-adjusted Borrowing Base to the previously-existing Borrowing Base is equal to the ratio of the as-adjusted Conforming Borrowing Base to the previously-existing Conforming Borrowing Base. In the event Required Banks elect to redetermine the Borrowing Base and the Conforming Borrowing Base in accordance with this Section 4.4, Administrative Agent shall notify Borrower promptly, but in any event no less than one (1) Domestic Business Day prior to the consummation of the Asset Disposition, of the amount of the Borrowing Base and the Conforming Borrowing Base as redetermined, which Borrowing Base and Conforming Borrowing Base shall be effective as of the date specified in such notice, and shall remain in effect for all purposes of this Agreement until the next Redetermination. Notwithstanding anything to the contrary contained herein, Borrower agrees that any such Redetermination pursuant to this Section 4.4 shall not be construed or deemed to be a Special Redetermination hereunder; and

(b) the Borrowing Base and the Conforming Borrowing Base shall be redetermined in connection with, and simultaneously with, the consummation of a Specified Asset Sale as follows: (i)(A) in the event the sale of the Midway Loop Assets occurs prior to the sale of the Xxxxxx Assets, the Conforming Borrowing Base will be automatically reduced to be $220,000,000 and the Borrowing Base will be automatically reduced to be $245,000,000 (in each case without the need for any additional Bank approval), (B) in the event the sale of the Xxxxxx Assets occurs prior to the sale of the Midway Loop Assets, the Conforming Borrowing Base will be automatically reduced to be $240,000,000 and the Borrowing Base will be automatically reduced to be $270,000,000 (in each case without the need for any additional Bank approval); provided, that, if either Specified Asset Sale is consummated prior to February 1, 2009, Borrower shall have the right to request an additional Redetermination upon the closing of the first Specified Asset Sale to occur, and (ii) upon the completion of both Specified Asset Sales, the Conforming Borrowing Base and the Borrowing Base will each be automatically reduced to be $195,000,000 (without the need for any additional Bank approval); provided, that, if both Specified Asset Sales are consummated prior to February 1, 2009, Borrower shall have the right to request an additional Redetermination upon the closing of the second such sale to occur

(which right to request an additional Redetermination shall be in addition to Borrower’s right to request an additional Redetermination set forth in clause (i) of Section 4.4(b)); and

(c) prior to the Conforming Date, the Borrowing Base shall be automatically reduced in connection with any Prepayment Event, without the need for any additional Bank approval, as set forth in Section 2.6(c) hereof.

Notwithstanding anything to the contrary contained in Section 4.4(b), if, immediately prior to a Specified Asset Sale, the Borrowing Base or Conforming Borrowing Base is lower than the applicable amounts to which Section 4.4(b) requires the Borrowing Base and the Conforming Borrowing Base be reduced in connection with a Specified Asset Sale, there shall be no adjustment to the Borrowing Base or the Conforming Borrowing Base, as applicable, pursuant to Section 4.4(b).

Section 4.5 Borrowing Base Deficiency. To the extent a Borrowing Base Deficiency exists after giving effect to any Redetermination (other than in connection with a Redetermination pursuant to Section 4.4 hereof), Borrower shall, within ten (10) days following notice thereof from Administrative Agent, provide written notice (the “Election Notice”) to Administrative Agent stating the action which Borrower proposes to take to remedy such Borrowing Base Deficiency, and Borrower shall thereafter, at its option, either (a) within thirty (30) days following the delivery of the Election Notice, make a prepayment or prepayments of principal on the Revolving Loan in an amount sufficient to eliminate such Borrowing Base Deficiency, and if such Borrowing Base Deficiency cannot be eliminated pursuant to this Section 4.5 by prepayment of the Revolving Loan in full (as a result of outstanding Letter of Credit Exposure), Borrower shall also at such time deposit with Administrative Agent sufficient cash to be held by Administrative Agent to secure outstanding Letter of Credit Exposure in the manner contemplated by Section 2.1(b) as necessary to eliminate such Borrowing Base Deficiency, (b) eliminate such Borrowing Base Deficiency by making three (3) consecutive mandatory prepayments of principal on the Revolving Loan, each of which shall be in the amount of one-third (1/3rd) of the amount of such Borrowing Base Deficiency, commencing on the first Monthly Date following the delivery of the Election Notice, and continuing on each Monthly Date thereafter, (c) within ninety (90) days following the delivery of the Election Notice, submit (and pledge as collateral pursuant to Article V hereof) additional oil and gas properties owned by Borrower and its Subsidiaries for consideration in connection with the determination of the Borrowing Base and the Conforming Borrowing Base which Administrative Agent and Banks deem sufficient in their sole discretion to eliminate such Borrowing Base Deficiency, or (d) eliminate such Borrowing Base Deficiency through a combination of prepayments on the Revolving Loan and submission of additional oil and gas properties for inclusion in the Borrowing Base and the Conforming Borrowing Base as set forth in subclauses (a) and (c) above. Notwithstanding the foregoing, upon any Redetermination of the Borrowing Base or Conforming Borrowing Base pursuant to Section 4.4 hereof which results in a Borrowing Base Deficiency (or increase in an existing Borrowing Base Deficiency), Borrower shall, within one (1) Domestic Business Day of such Redetermination, make a mandatory prepayment of principal on the Revolving Loan in an amount sufficient to eliminate such Borrowing Base Deficiency.

Administrative Agent shall in all cases be fully protected in acting, or in refraining from acting, hereunder and under any other Loan Paper in accordance with written instructions signed by the Majority Banks, and such instructions and any action taken or failure to act pursuant thereto shall be binding on all of the Banks. The Banks hereby acknowledge that Administrative Agent shall be under no duty to take any discretionary action permitted to be taken by it pursuant to the provisions of this Agreement or any other Loan Paper unless it shall be requested in writing to do so by Majority Banks. Administrative Agent shall be fully justified in failing or refusing to take any action hereunder and under any other Loan Paper unless it shall first be indemnified to its satisfaction by the Banks pro rata against any and all liability, cost and expense that it may incur by reason of taking or continuing to take any such action.

Section 12.6 Employment of Agents and Counsel. Administrative Agent may execute any of its duties as Administrative Agent hereunder and under any other Loan Paper by or through employees, agents, and attorneys-in-fact and shall not be answerable to the Banks, except as to money or securities received by it or its authorized agents, for the default or misconduct of any such agents or attorneys-in-fact selected by it with reasonable care. Administrative Agent shall be entitled to advice of counsel concerning the contractual arrangement between Administrative Agent and the Banks and all matters pertaining to Administrative Agent’s duties hereunder and under any other Loan Paper.

Section 12.7 Reliance on Documents; Counsel. Administrative Agent shall be entitled to rely upon any Note, notice, consent, certificate, affidavit, letter, telegram, statement, paper or document believed by it to be genuine and correct and to have been signed or sent by the proper Person or Persons, and, in respect to legal matters, upon the opinion of counsel selected by Administrative Agent, which counsel may be employees of Administrative Agent.

Section 12.8 Administrative Agent’s Reimbursement and Indemnification. Banks agree to reimburse and indemnify Administrative Agent ratably in proportion to their respective Commitments (or, if the Commitments have been terminated, in proportion to their Commitments immediately prior to such termination) (a) for any amounts not reimbursed by Borrower for which Administrative Agent is entitled to reimbursement by Borrower under the

Loan Papers, (b) for any other expenses incurred by Administrative Agent on behalf of the Banks, in connection with the preparation, execution, delivery, administration and enforcement of the Loan Papers (including, without limitation, for any expenses incurred by Administrative Agent in connection with any dispute between Administrative Agent and any Bank or between two or more of the Banks) and (c) for any liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind and nature whatsoever which may be imposed on, incurred by or asserted against Administrative Agent in any way relating to or arising out of the Loan Papers or any other document delivered in connection therewith or the transactions contemplated thereby (including, without limitation, for any such amounts incurred by or asserted against Administrative Agent in connection with any dispute between Administrative Agent and any Bank or between two or more of the Banks), or the enforcement of any of the terms of the Loan Papers or of any such other documents; provided that no Bank shall be liable for any of the foregoing to the extent any of the foregoing is found in a final non-appealable judgment by a court of competent jurisdiction to have resulted from the gross negligence or willful misconduct of Administrative Agent. The obligations of the Banks under this Section 12.8 shall survive payment of the Obligations and termination of this Agreement.

Section 12.9 Notice of Default. Administrative Agent shall not be deemed to have knowledge or notice of the occurrence of any Default or Event of Default hereunder unless Administrative Agent has received written notice from a Bank or Borrower referring to this Agreement describing such Default or Event of Default and stating that such notice is a “notice of default”. In the event that Administrative Agent receives such a notice, Administrative Agent shall give prompt notice thereof to the Banks.

Section 12.10 Rights as a Bank. In the event Administrative Agent is a Bank, Administrative Agent shall have the same rights and powers hereunder and under any other Loan Paper with respect to its Commitment and its Revolving Loans as any Bank and may exercise the same as though it were not Administrative Agent, and the term “Bank” or “Banks” shall, at any time when Administrative Agent is a Bank, unless the context otherwise indicates, include in its individual capacity. Administrative Agent and its Affiliates may accept deposits from, lend money to, and generally engage in any kind of trust, debt, equity or other transaction, in addition to those contemplated by this Agreement or any other Loan Paper, with Borrower or any of its Subsidiaries in which Borrower or such Subsidiary is not restricted hereby from engaging with any other Person.

Section 12.11 Bank Credit Decision. Each Bank acknowledges that it has, independently and without reliance upon Administrative Agent, Joint Lead Arrangers, Joint Bookrunners or any other Agent or Bank and based on the financial statements prepared by Borrower and such other documents and information as it has deemed appropriate, made its own credit analysis and decision to enter into this Agreement and the other Loan Papers. Each Bank also acknowledges that it will, independently and without reliance upon Administrative Agent, Joint Lead Arrangers, Joint Bookrunners or any other Agent or Bank and based on such documents and information as it shall deem appropriate at the time, continue to make its own credit decisions in taking or not taking action under this Agreement and the other Loan Papers.

Section 12.12 Successor Administrative Agent. Administrative Agent may resign at any time by giving written notice thereof to Banks and Borrower, such resignation to be effective upon the appointment of a successor Administrative Agent or, if no successor Administrative Agent has been appointed, forty-five (45) days after the retiring Administrative Agent gives notice of its intention to resign. Upon any such resignation, Majority Banks shall have the right to appoint, on behalf of Borrower and the Banks, a successor Administrative Agent, which shall be approved by Borrower, such approval not to be unreasonably withheld; provided, that, Borrower shall not have the right to approve any successor Administrative Agent appointed during the continuance of any Default. If no successor Administrative Agent shall have been so appointed by Majority Banks within thirty (30) days after the resigning Administrative Agent’s giving notice of its intention to resign, then the resigning Administrative Agent may appoint, on behalf of Borrower and Banks, a successor Administrative Agent which shall be approved by Borrower, such approval not to be unreasonably withheld; provided, that, Borrower shall not have the right to approve any successor Administrative Agent appointed during the continuance of any Default. If Administrative Agent has resigned and no successor Administrative Agent has been appointed, Banks may perform all the duties of Administrative Agent hereunder and Borrower shall make all payments in respect of the Obligations to the applicable Bank and for all other purposes shall deal directly with the Banks; provided, however, that the Administrative Agent shall retain all rights and obligations under and with respect to each of the Mortgages, the Borrower Pledge Agreement, the Subsidiary Pledge Agreements and all related financing statements and any other financing statements, agreements, documents or instruments relating thereto or contemplated hereby or thereby until such time as a successor Administrative Agent shall have accepted an appointment hereunder. No successor Administrative Agent shall be deemed to be appointed hereunder until such successor Administrative Agent has accepted the appointment. Any such successor Administrative Agent shall be a commercial bank having capital and retained earnings of at least $100,000,000. Upon the acceptance of any appointment as Administrative Agent hereunder by a successor Administrative Agent, such successor Administrative Agent shall thereupon succeed to and become vested with all the rights, powers, privileges and duties of the resigning Administrative Agent. Upon the effectiveness of the resignation of Administrative Agent, the resigning Administrative Agent shall be discharged from its duties and obligations hereunder and under the Loan Papers. After the effectiveness of the resignation of an Administrative Agent, the provisions of this Article XII shall continue in effect for the benefit of such Administrative Agent in respect of any actions taken or omitted to be taken by it while it was acting as Administrative Agent hereunder and under the other Loan Papers. In the event that there is a successor to Administrative Agent by merger, or Administrative Agent assigns its duties and obligations to an Affiliate pursuant to this Section 12.12, then the term “Prime Rate” as used in this Agreement shall mean the prime rate, base rate or other analogous rate of the new Administrative Agent.

Section 12.13 Delegation to Affiliates. Borrower and Banks agree that Administrative Agent may delegate any of its duties under this Agreement to any of its Affiliates. Any such Affiliate (and such Affiliate’s directors, officers, agents and employees) which performs duties in connection with this Agreement shall be entitled to the same benefits of the indemnification, waiver and other protective provisions to which Administrative Agent is entitled under Article XII and Article XIII.

Section 12.14 Execution of Collateral Documents. Without limiting the powers and authority of Administrative Agent described herein, the Banks hereby empower and authorize Administrative Agent to execute and deliver to Borrower on their behalf the Mortgages (including, without limitation, any amendments to the Existing Mortgages), the Borrower Pledge Agreements, the Subsidiary Pledge Agreements and all related financing statements and any other financing statements, agreements, documents or instruments as shall be necessary or appropriate to effect the purposes of the foregoing instruments.

Section 12.15 Collateral Releases. Banks hereby empower and authorize Administrative Agent to execute and deliver to Borrower on their behalf any agreements, documents or instruments as shall be necessary or appropriate to effect any releases of collateral which shall be permitted by the terms hereof or of any other Loan Paper or which shall otherwise have been approved by Majority Banks (or, if required by the terms of Section 14.5, all of the Banks) in writing.

Section 12.16 Agents. None of the Banks (if any) identified in, or appointed at any time under, this Agreement as a “Documentation Agent,” a “Co-Documentation Agent,” a “Syndication Agent”, a “Co-Syndication Agent”, a “Joint Lead Arranger” and/or a “Joint Bookrunner” shall have any right, power, obligation, liability, responsibility or duty under this Agreement other than those applicable to all Banks as such. Without limiting the foregoing, none of any such Agents shall have or be deemed to have a fiduciary relationship with any Bank. Each Bank hereby makes the same acknowledgments with respect to any such Agents as it makes with respect to Administrative Agent in Section 12.11.

ARTICLE XIII
CHANGE IN CIRCUMSTANCES

Section 13.1 Increased Cost and Reduced Return.

(a) If, after the date hereof, the adoption of any applicable law, rule, or regulation, or any change in any applicable law, rule, or regulation, or any change in the interpretation or administration thereof by any Governmental Authority, central bank, or comparable agency charged with the interpretation or administration thereof, or compliance by any Bank (or its Applicable Lending Office) with any request or directive (whether or not having the force of law) of any such Governmental Authority, central bank, or comparable agency:

(i) shall subject such Bank (or its Applicable Lending Office) to any tax, duty, or other charge with respect to any Eurodollar Loans, its Note, or its obligation to make Eurodollar Loans, or change the basis of taxation of any amounts payable to such Bank (or its Applicable Lending Office) under this Agreement or its Note in respect of any Eurodollar Loans (other than taxes imposed on the overall net income of such Bank or such Applicable Lending Office);

(ii) shall impose, modify, or deem applicable any reserve, special deposit, assessment, compulsory loan, or similar requirement (other than the Reserve Requirement utilized in the determination of the Adjusted Eurodollar Rate) relating to any extensions of credit or other assets of, or any deposits with or other liabilities or

commitments of, such Bank (or its Applicable Lending Office), including the Commitment of such Bank hereunder; or

(iii) shall impose on such Bank (or its Applicable Lending Office) or on the London interbank market any other condition affecting this Agreement or its Note or any of such extensions of credit or liabilities or commitments;

and the result of any of the foregoing is to increase the cost to such Bank (or its Applicable Lending Office) of making, Converting into, Continuing, or maintaining any Eurodollar Loans or to reduce any sum received or receivable by such Bank (or its Applicable Lending Office) under this Agreement or its Note with respect to any Eurodollar Loans, then the Borrower shall pay to such Bank on demand such amount or amounts as will compensate such Bank for such increased costs or reductions incurred or experienced within one hundred twenty (120) days of such demand. If any Bank requests compensation by Borrower under this Section 13.1(a), the Borrower may, by notice to such Bank (with a copy to Administrative Agent), suspend the obligation of such Bank to make or Continue Eurodollar Loans or to Convert all or part of the Base Rate Loan owing to such Bank into Eurodollar Loans, until the event or condition giving rise to such request ceases to be in effect (in which case the provisions of Section 13.4 shall be applicable); provided, that such suspension shall not affect the right of such Bank to receive the compensation so requested.

(b) If, after the date hereof, any Bank shall have determined that the adoption of any applicable law, rule, or regulation regarding capital adequacy or any change therein or in the interpretation or administration thereof by any Governmental Authority, central bank, or comparable agency charged with the interpretation or administration thereof, or any request or directive regarding capital adequacy (whether or not having the force of law) of any such Governmental Authority, central bank, or comparable agency, has or would have the effect of reducing the rate of return on the capital of such Bank or any corporation controlling such Bank as a consequence of such Bank’s obligations hereunder to a level below that which such Bank or such corporation could have achieved but for such adoption, change, request, or directive (taking into consideration its policies with respect to capital adequacy), then, from time to time upon demand, Borrower shall pay to such Bank such additional amount or amounts as will compensate such Bank for such reductions experienced within one hundred twenty (120) days of such demand; provided, that, if such adoption, change, request or directive giving rise to such reductions is retroactive, then the one hundred twenty (120) day period referred to above shall be extended to include the period of retroactive effect thereof.

(c) Each Bank shall promptly notify Borrower and Administrative Agent of any event of which it has knowledge, occurring after the date hereof, which will entitle such Bank to compensation pursuant to this Section 13.1 and will designate a different Applicable Lending Office if such designation will avoid the need for, or reduce the amount of, such compensation and will not, in the judgment of such Bank, be otherwise disadvantageous to it. Any Bank claiming compensation under this Section 13.1 shall furnish to Borrower and Administrative Agent a statement setting forth the additional amount or amounts to be paid to it hereunder which shall be conclusive in the absence of manifest error. In determining such amount, such Bank may use any reasonable averaging and attribution methods.

Section 13.2 Limitation on Type of Loans. If on or prior to the first day of any Interest Period for any Eurodollar Loan:

(a) Administrative Agent determines (which determination shall be conclusive) that by reason of circumstances affecting the relevant market, adequate and reasonable means do not exist for ascertaining the Eurodollar Rate for such Interest Period; or

(b) Majority Banks determine (which determination shall be conclusive) and notify Administrative Agent that the Adjusted Eurodollar Rate will not adequately and fairly reflect the cost to Banks of funding Eurodollar Loans for such Interest Period;

then Administrative Agent shall give Borrower prompt notice thereof specifying the relevant Type of Revolving Loans and the relevant amounts or periods, and so long as such condition remains in effect, Banks shall be under no obligation to make additional Revolving Loans of such Type, Continue Revolving Loans of such Type, or to Convert Revolving Loans of any other Type into Revolving Loans of such Type, and Borrower shall, on the last day(s) of the then current Interest Period(s) for the outstanding Revolving Loans of the affected Type, either prepay such Revolving Loans or Convert such Revolving Loans into another Type of Revolving Loan in accordance with the terms of this Agreement.

Section 13.3 Illegality. Notwithstanding any other provision of this Agreement, in the event that it becomes unlawful for any Bank or its Applicable Lending Office to make, maintain, or fund Eurodollar Loans hereunder, then such Bank shall promptly notify Borrower thereof and such Bank’s obligation to make or Continue Eurodollar Loans and to Convert other Types of Revolving Loans into Eurodollar Loans shall be suspended until such time as such Bank may again make, maintain, and fund Eurodollar Loans (in which case the provisions of Section 13.4 shall be applicable).

Section 13.4 Treatment of Affected Loans. If the obligation of any Bank to make particular Eurodollar Loans or to Continue Revolving Loans, or to Convert Revolving Loans of another Type into Revolving Loans of a particular Type shall be suspended pursuant to Section 13.1 or Section 13.3 hereof (Revolving Loans of such Type being herein called “Affected Loans” and such Type being herein called the “Affected Type”), such Bank’s Affected Loans shall be automatically Converted into the Base Rate Loan on the last day(s) of the then current Interest Period(s) for Affected Loans (or, in the case of a Conversion required by Section 13.3 hereof, on such earlier date as such Bank may specify to Borrower with a copy to Administrative Agent) and, unless and until such Bank gives notice as provided below that the circumstances specified in Section 13.1 or Section 13.3 hereof that gave rise to such Conversion no longer exist:

(a) to the extent that such Bank’s Affected Loans have been so Converted, all payments and prepayments of principal that would otherwise be applied to such Bank’s Affected Loans shall be applied instead to the Base Rate Loan; and

(b) all Revolving Loans that would otherwise be made or Continued by such Bank as Revolving Loans of the Affected Type shall be made or Continued instead as part of the Base Rate Loan, and all Revolving Loans of such Bank that would otherwise be Converted into

Revolving Loans of the Affected Type shall be Converted instead into (or shall remain) as part of the Base Rate Loan.

If such Bank gives notice to Borrower (with a copy to Administrative Agent) that the circumstances specified in Section 13.1 or Section 13.3 hereof that gave rise to the Conversion of such Bank’s Affected Loans pursuant to this Section 13.4 no longer exist (which such Bank agrees to do promptly upon such circumstances ceasing to exist) at a time when Revolving Loans of the Affected Type made by other Banks are outstanding, such Bank’s portion of the Base Rate Loan shall be automatically Converted, on the first day(s) of the next succeeding Interest Period(s) for such outstanding Revolving Loans of the Affected Type, to the extent necessary so that, after giving effect thereto, all Revolving Loans held by Banks holding Revolving Loans of the Affected Type and by such Bank are held pro rata (as to principal amounts, Types and Interest Periods) in accordance with their respective Commitments.

Section 13.5 Compensation. Upon the request of any Bank, Borrower shall pay to such Bank such amount or amounts as shall be sufficient (in the reasonable opinion of such Bank) to compensate it for any loss, cost, or expense (including loss of anticipated profits) incurred by it as a result of:

(a) any payment, prepayment, or Conversion of a Eurodollar Loan for any reason (including, without limitation, the acceleration of the Revolving Loan) on a date other than the last day of the Interest Period for such Loan; or

(b) any failure by the Borrower for any reason (including, without limitation, the failure of any condition precedent specified in Article VI to be satisfied) to borrow, Convert, Continue, or prepay a Eurodollar Loan on the date for such Borrowing, Conversion, Continuation, or prepayment specified in the relevant Request for Borrowing, Notice of Continuation or Conversion, or other notice of Borrowing, prepayment, Continuation, or Conversion under this Agreement.

Section 13.6 Taxes.

(a) Any and all payments by Borrower to or for the account of any Bank or Administrative Agent hereunder or under any other Loan Paper shall be made free and clear of and without deduction for any and all present or future Taxes, duties, levies, imposts, deductions, charges or withholdings, and all liabilities with respect thereto, excluding, in the case of each Bank and Administrative Agent, Taxes imposed on its income, and franchise Taxes imposed on it (all such non-excluded Taxes, duties, levies, imposts, deductions, charges, withholdings, and liabilities being hereinafter referred to in this Section 13.6 as “Non-Excluded Taxes”). If Borrower shall be required by Law to deduct any Non-Excluded Taxes from or in respect of any sum payable under this Agreement or any other Loan Paper to any Bank or Administrative Agent, (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 13.6) such Bank or Administrative Agent receives an amount equal to the sum it would have received had no such deductions been made, (ii) Borrower shall make such deductions, (iii) Borrower shall pay the full amount deducted to the relevant taxation authority or other authority in accordance with applicable Law, and (iv) Borrower shall furnish to Administrative Agent, at its

address set forth on Schedule 1.1 hereto, the original or a certified copy of a receipt evidencing payment thereof.

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

(c) Borrower agrees to indemnify each Bank and Administrative Agent for the full amount of Non-Excluded Taxes and Other Taxes (including, without limitation, any Non-Excluded Taxes or Other Taxes imposed or asserted by any jurisdiction on amounts payable under this Section 13.6) paid by such Bank or Administrative Agent (as the case may be) and any liability (including penalties, interest, and expenses) arising therefrom or with respect thereto.

(d) Each Bank organized under the Laws of a jurisdiction outside the United States, on or prior to the date of its execution and delivery of this Agreement in the case of each Bank listed on Schedule 1.1 hereto and on or prior to the date on which it becomes a Bank in the case of each other Bank, and from time to time thereafter if requested in writing by Borrower or Administrative Agent (but only so long as such Bank remains lawfully able to do so), shall provide Borrower and Administrative Agent, at the time or times prescribed by applicable Law, with such properly completed and executed documentation prescribed by applicable Law (or reasonably requested by Borrower) certifying that such Bank is entitled to benefits under an income tax treaty to which the United States is a party which reduces the rate of withholding tax on payments of interest or certifying that the income receivable pursuant to this Agreement is effectively connected with the conduct of a trade or business in the United States, and certifying that such Bank is entitled to an exemption from or a reduced rate of tax on payments pursuant to this Agreement or any of the other Loan Papers.

(e) For any period with respect to which a Bank has failed to provide Borrower and Administrative Agent with the appropriate form pursuant to Section 13.6(d) (unless such failure is due to a change in treaty, law, or regulation occurring subsequent to the date on which a form originally was required to be provided), such Bank shall not be entitled to indemnification under Section 13.6(a), Section 13.6(b) or Section 13.6(c) with respect to Non-Excluded Taxes imposed by the United States; provided, however, that should a Bank, which is otherwise exempt from or subject to a reduced rate of withholding Tax, become subject to Non-Excluded Taxes because of its failure to deliver a form required hereunder, Borrower shall take such steps as such Bank shall reasonably request to assist such Bank to recover such Non-Excluded Taxes.

(f) If Borrower is required to pay additional amounts to or for the account of any Bank pursuant to this Section 13.6, then such Bank will agree to use reasonable efforts to change the jurisdiction of its Applicable Lending Office so as to eliminate or reduce any such additional payment which may thereafter accrue if such change, in the judgment of such Bank, is not otherwise disadvantageous to such Bank.

(g) Within thirty (30) days after the date of any payment of Non-Excluded Taxes, Borrower shall furnish to Administrative Agent the original or a certified copy of a receipt evidencing such payment.

(h) Without prejudice to the survival of any other agreement of Borrower hereunder, the agreements and obligations of Borrower contained in this Section 13.6 shall survive the termination of the Commitments and the payment in full of the Revolving Loan.

Section 13.7 Discretion of Banks as to Manner of Funding. Notwithstanding any provisions of this Agreement to the contrary, each Bank shall be entitled to fund and maintain its funding of all or any part of its Commitment in any manner it sees fit, it being understood, however, that for the purposes of this Agreement all determinations hereunder shall be made as if such Bank had actually funded and maintained each Eurodollar Loan during the Interest Period for such Eurodollar Loan through the purchase of deposits having a maturity corresponding to the last day of such Interest Period and bearing an interest rate equal to the Adjusted Eurodollar Rate for such Interest Period.

(a) Upon the occurrence and during the continuance of any Event of Default, each Bank (and each of its Affiliates) is hereby authorized at any time and from time to time, 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 and other indebtedness at any time owing by such Bank (or any of its Affiliates) to or for the credit or the account of any Credit Party against any and all of the Obligations, irrespective of whether such Bank shall have made any demand under this Agreement or Note held by such and although such obligations may be unmatured. Each Bank agrees promptly to notify the affected Credit Party after any such set-off and application made by such Bank; provided, however, that the failure to give such notice shall not affect the validity of such set-off and application. The rights of each Bank under this Section 14.4 are in addition to other rights and remedies (including, without limitation, other rights of set-off) that such Bank may have.

(b) If any Bank (a “benefitted Bank”) shall at any time receive any payment of all or part of the amounts owing to it, or interest thereon, or receive any collateral in respect thereof (whether voluntarily or involuntarily, by set-off, or otherwise), in a greater proportion than any such payment to or collateral received by any other Bank, if any, in respect of such other Bank’s amounts owing to it, or interest thereon, such benefitted Bank shall purchase for cash from the other Banks a participating interest in such portion of each such other Bank’s amounts owing to it, or shall provide such other Banks with the benefits of any such collateral, or the proceeds thereof, as shall be necessary to cause such benefitted Bank to share the excess payment or benefits of such collateral or proceeds ratably with each other Bank; provided, however, that if all or any portion of such excess payment or benefits is thereafter recovered from such benefitted Bank, such purchase shall be rescinded, and the purchase price and benefits returned, to the extent of such recovery, but without interest. Borrower agrees that any Bank so purchasing a participation from a Bank pursuant to this Section 14.4 may, to the fullest extent permitted by Law, exercise all of its rights of payment (including the right of set-off) with respect to such participation as fully as if such Person were the direct creditor of Borrower in the amount of such participation.

Section 14.5 Amendments and Waivers. Subject to the provisions of Section 14.10(f), any provision of this Agreement, the Notes or any other Loan Paper may be amended or waived if, but only if, such amendment or waiver is in writing and is signed by Borrower and Majority Banks (and, if the rights or duties of any Agent or Letter of Credit Issuer are affected thereby, by such Agent or Letter of Credit Issuer, as applicable); provided that no such

amendment or waiver shall, (1) unless signed by all Banks, (a) increase the Commitment of any Bank, (b) reduce the principal of or rate of interest on any Revolving Loan or any fees or other amounts payable hereunder or for termination of any Commitment, (c) change the percentage of the Total Commitment, or the number of Banks which shall be required for Banks or any of them to take any action under this Section 14.5 or any other provision of this Agreement, (d) extend the due date for, or forgive any principal, interest, fees or reimbursement obligations due hereunder, (e) release any material guarantor or other material party liable for all or any part of the Obligations or release any material part of the collateral for the Obligations or any part thereof other than releases required pursuant to sales of collateral which are expressly permitted by Section 9.5 hereof, (f) amend or modify any of the provisions of Article IV hereof or the definitions of any terms defined therein, (g) permit the Borrower to assign its rights hereunder, (h) increase any Borrowing Base (or Conforming Borrowing Base, as applicable) above the Borrowing Base (or Conforming Borrowing Base, as applicable) then in effect or (i) establish a Borrowing Base in an amount greater than the Conforming Borrowing Base or (2) unless signed by Required Banks, decrease or reaffirm the Borrowing Base or Conforming Borrowing Base. Notwithstanding anything to the contrary herein, no Defaulting Bank shall have any right to approve or disapprove any amendment, waiver or consent hereunder, except that the Commitment of such Bank may not be increased or extended without the consent of such Bank.

Section 14.6 Survival. All representations, warranties and covenants made by any Credit Party herein or in any certificate or other instrument delivered by it or in its behalf under the Loan Papers shall be considered to have been relied upon by Banks and shall survive the delivery to Banks of such Loan Papers or the extension of the Revolving Loan (or any part thereof), regardless of any investigation made by or on behalf of Banks. The indemnity provided in Section 14.3(b) herein shall survive the repayment of all Obligations and/or the discharge or release of any Lien granted hereunder or in any other Loan Paper, contract or agreement between Borrower or any other Credit Party and any Agent or any Bank.

Section 14.7 Limitation on Interest. Regardless of any provision contained in the Loan Papers, Banks shall never be entitled to receive, collect, or apply, as interest on the Revolving Loan, any amount in excess of the Maximum Lawful Rate, and in the event any Bank ever receives, collects or applies as interest any such excess, such amount which would be deemed excessive interest shall be deemed a partial prepayment of principal and treated hereunder as such; and if the Revolving Loan is paid in full, any remaining excess shall promptly be paid to Borrower. In determining whether or not the interest paid or payable under any specific contingency exceeds the Maximum Lawful Rate, Borrower and Banks shall, to the extent permitted under applicable Law, (a) characterize any non-principal payment as an expense, fee or premium rather than as interest, (b) exclude voluntary prepayments and the effects thereof and (c) amortize, prorate, allocate and spread, in equal parts, the total amount of the interest throughout the entire contemplated term of the Revolving Loan, so that the interest rate is the Maximum Lawful Rate throughout the entire term of the Revolving Loan; provided, however, that if the unpaid principal balance thereof is paid and performed in full prior to the end of the full contemplated term thereof, and if the interest received for the actual period of existence thereof exceeds the Maximum Lawful Rate, Banks shall refund to Borrower the amount of such excess and, in such event, Banks shall not be subject to any penalties provided by any Laws for contracting for, charging, taking, reserving or receiving interest in excess of the Maximum Lawful Rate.

Section 14.8 Invalid Provisions. If any provision of the Loan Papers is held to be illegal, invalid, or unenforceable under present or future Laws effective during the term thereof, such provision shall be fully severable, the Loan Papers shall be construed and enforced as if such illegal, invalid, or unenforceable provision had never comprised a part thereof, and the remaining provisions thereof shall remain in full force and effect and shall not be affected by the illegal, invalid, or unenforceable provision or by its severance therefrom. Furthermore, in lieu of such illegal, invalid, or unenforceable provision there shall be added automatically as a part of the Loan Papers a provision as similar in terms to such illegal, invalid, or unenforceable provision as may be possible and be legal, valid and enforceable.

Section 14.9 Waiver of Consumer Credit Laws. Pursuant to Chapter 346 of the Texas Finance Code, as amended, Borrower agrees that such Chapter 346 shall not govern or in any manner apply to the Revolving Loan.

Section 14.10 Assignments and Participations.

(a) Successors and Assigns. The terms and provisions of the Loan Papers shall be binding upon and inure to the benefit of Borrower and Banks and their respective successors and assigns permitted hereby, except that (i) Borrower shall not have the right to assign its rights or obligations under the Loan Papers without the prior written consent of each Bank, (ii) any assignment by any Bank must be made in compliance with Section 14.10(c), and (iii) any transfer by participation must be made in compliance with Section 14.10(b). Any attempted assignment or transfer by any party not made in compliance with this Section 14.10(a) shall be null and void, unless such attempted assignment or transfer is treated as a participation in accordance with Section 14.10(b). The parties to this Agreement acknowledge that clause (ii) of this Section 14.10(a) relates only to absolute assignments and this Section 14.10(a) does not prohibit assignments creating security interests, including, without limitation, (x) any pledge or assignment by any Bank of all or any portion of its rights under this Agreement and any Note to a Federal Reserve Bank or (y) in the case of a Bank which is a Fund, any pledge or assignment of all or any portion of its rights under this Agreement and any Note to its trustee in support of its obligations to its trustee; provided, however, that no such pledge or assignment creating a security interest shall release the transferor Bank from its obligations hereunder unless and until the parties thereto have complied with the provisions of Section 14.10(c). Administrative Agent may treat the Person which made any Revolving Loan or which holds any Note as the owner thereof for all purposes hereof unless and until such Person complies with Section 14.10(c); provided, however, that Administrative Agent may in its discretion (but shall not be required to) follow instructions from the Person which made any Revolving Loan or which holds any Note to direct payments relating to such Revolving Loan or Note to another Person. Any assignee of the rights to any Revolving Loan or any Note agrees by acceptance of such assignment to be bound by all the terms and provisions of the Loan Papers. Any request, authority or consent of any Person, who at the time of making such request or giving such authority or consent is the owner of the rights to any Revolving Loan (whether or not a Note has been issued in evidence thereof), shall be conclusive and binding on any subsequent holder or assignee of the rights to such Revolving Loan.

(b) Participations.

(i) Any Bank may at any time sell to one or more banks or other entities (“Participants”) participating interests in any Revolving Loan owing to such Bank, any Note held by such Bank, any Commitment of such Bank or any other interest of such Bank under the Loan Papers. In the event of any such sale by a Bank of participating interests to a Participant, such Bank’s obligations under the Loan Papers shall remain unchanged, such Bank shall remain solely responsible to the other parties hereto for the performance of such obligations, such Bank shall remain the owner of its Revolving Loans and the holder of any Note issued to it in evidence thereof for all purposes under the Loan Papers, all amounts payable by Borrower under this Agreement shall be determined as if such Bank had not sold such participating interests, and Borrower and Administrative Agent shall continue to deal solely and directly with such Bank in connection with such Bank’s rights and obligations under the Loan Papers.

(ii) Each Bank shall retain the sole right to approve, without the consent of any Participant, any amendment, modification or waiver of any provision of the Loan Papers other than any amendment, modification or waiver with respect to any Revolving Loan or Commitment in which such Participant has an interest which would require consent of all of the Banks pursuant to the terms of Section 14.5 or of any other Loan Paper.

(iii) Borrower agrees that each Participant shall be deemed to have the right of setoff provided in Section 14.4 in respect of its participating interest in amounts owing under the Loan Papers to the same extent as if the amount of its participating interest were owing directly to it as a Bank under the Loan Papers; provided, that each Bank shall retain the right of setoff provided in Section 14.4 with respect to the amount of participating interests sold to each Participant. Banks agree to share with each Participant, and each Participant, by exercising the right of setoff provided in Section 14.4, agrees to share with each Bank, any amount received pursuant to the exercise of its right of setoff, such amounts to be shared in accordance with Section 14.4 as if each Participant were a Bank. Borrower further agrees that each Participant shall be entitled to the yield protection provisions contained in Article XIII to the same extent as if it were a Bank and had acquired its interest by assignment pursuant to Section 14.10(c); provided, that (A) a Participant shall not be entitled to receive any greater payment under Article XIII than the Bank who sold the participating interest to such Participant would have received had it retained such interest for its own account, unless the sale of such interest to such Participant is made with the prior written consent of Borrower, and (B) any Participant not incorporated under the laws of the United States of America or any State thereof agrees to comply with the provisions of Section 13.6 to the same extent as if it were a Bank.

(i) Any Bank may at any time assign to one or more banks or other entities (“Purchasers”) all or any part of its rights and obligations under the Loan Papers. The parties to such assignment shall execute and deliver an Assignment and Acceptance

Agreement (herein so called) which shall be substantially in the form of Exhibit J or in such other form as may be agreed to by the parties thereto. Each such assignment with respect to a Purchaser which is not a Bank or an Affiliate of a Bank or an Approved Fund shall either be in an amount equal to the entire applicable Commitment and Revolving Loans of the assigning Bank or (unless each of Borrower and Administrative Agent otherwise consents) be in an aggregate amount not less than $5,000,000. The amount of the assignment shall be based on the Commitment or outstanding Revolving Loans (if the Commitment has been terminated) subject to the assignment, determined as of the date of such assignment or as of the “Effective Date,” if the “Effective Date” is specified in the Assignment and Acceptance Agreement.

(ii) The consent of Borrower shall be required prior to an assignment becoming effective unless Purchaser is a Bank, an Affiliate of a Bank or an Approved Fund, provided that the consent of Borrower shall not be required if a Default has occurred and is continuing. The consent of Administrative Agent shall be required prior to an assignment becoming effective unless the Purchaser is a Bank, an Affiliate of a Bank or an Approved Fund. The consent of Letter of Credit Issuer shall be required prior to an assignment of a Commitment becoming effective unless Purchaser is a Bank, an Affiliate of a Bank or an Approved Fund. Any consent required under this Section 14.10(c)(ii) shall not be unreasonably withheld or delayed.

(iii) Upon (A) delivery to Administrative Agent of an Assignment and Acceptance Agreement, together with any consents required by Section 14.10(c)(i) and (ii), and (B) payment of a $3,500 fee to Administrative Agent for processing such assignment (unless such fee is waived by Administrative Agent), such assignment shall become effective on the effective date specified in such Assignment and Acceptance Agreement. On and after the effective date of such assignment, such Purchaser shall for all purposes be a Bank party to this Agreement and any other Loan Paper executed by or on behalf of Banks and shall have all the rights and obligations of a Bank under the Loan Papers, to the same extent as if it were an original party thereto, and the transferor Bank shall be released with respect to the Commitment and Revolving Loans assigned to such Purchaser without any further consent or action by Borrower, Banks or Administrative Agent. In the case of an assignment covering all of the assigning Bank’s rights and obligations under this Agreement, such Bank shall cease to be a Bank hereunder but shall continue to be entitled to the benefits of, and subject to, those provisions of this Agreement and the other Loan Papers which survive payment of the Obligations and termination of the applicable agreement. Any assignment or transfer by a Bank of rights or obligations under this Agreement that does not comply with this Section 14.10(c) shall be treated for purposes of this Agreement as a sale by such Bank of a participation in such rights and obligations in accordance with Section 14.10(b). Upon the consummation of any assignment to a Purchaser pursuant to this Section 14.10(c), the transferor Bank, Administrative Agent and Borrower shall make appropriate arrangements so that new Notes or, as appropriate, replacement Notes are issued to such transferor Bank (if such transferor Bank requests a Note) and new Notes or, as appropriate, replacement Notes, are issued to such Purchaser (if such Purchaser requests a Note), in each case in principal amounts reflecting their respective Commitments, as adjusted pursuant to such assignment.

(iv) Administrative Agent, acting solely for this purpose as an agent of Borrower, shall maintain at one of its offices in Chicago, Illinois or Dallas, Texas a copy of each Assignment and Acceptance Agreement delivered to it and a register for the recordation of the names and addresses of the Banks, and the Commitments of, and principal amounts of the Revolving Loans owing to, each Bank pursuant to the terms hereof from time to time (the “Register”). The entries in the Register shall be conclusive, and Borrower, Administrative Agent and Banks may treat each Person whose name is recorded in the Register pursuant to the terms hereof as a Bank hereunder for all purposes of this Agreement, notwithstanding notice to the contrary. The Register shall be available for inspection by Borrower and any Bank, at any reasonable time and from time to time upon reasonable prior notice.

(v) Notwithstanding anything to the contrary contained in this Agreement, in no case may a Bank assign all or a portion of its rights and obligations under this Agreement to the Borrower or to any Affiliate of the Borrower.

(d) Dissemination of Information. Borrower authorizes each Bank to disclose to any Participant or Purchaser or any other Person acquiring an interest in the Loan Papers by operation of law (each a “Transferee”) and any prospective Transferee any and all information in such Bank’s possession concerning the creditworthiness of Borrower and its Subsidiaries, including, without limitation, any information contained in any financial reports; provided, that, each Transferee and prospective Transferee agrees to be bound by Section 14.17 of this Agreement.

(e) Tax Treatment. If any interest in any Loan Paper is transferred to any Transferee which is not incorporated under the laws of the United States or any State thereof, the transferor Bank shall cause such Transferee, concurrently with the effectiveness of such transfer, to comply with the provisions of Section 13.6.

(f) Procedures for Commitment Increases and Addition of New Banks. This Agreement permits certain increases of a Bank’s Commitment and the admission of new Banks providing new Commitments, none of which requires any consent or approvals from the other Banks. Any amendment hereto for such a Commitment Increase or addition shall be in the form attached hereto as Exhibit L and, subject to the terms and conditions set forth in clause (ii) of Section 2.10 and in the form attached hereto as Exhibit L, shall only require the written signatures of Administrative Agent, Borrower, the Bank(s) being added or increasing their Commitment and, if a new Bank is being admitted, the Letter of Credit Issuer. On the effective date of any such Commitment Increase, Administrative Agent, Borrower and applicable Banks shall make appropriate arrangements so that new Notes or, as appropriate, replacement Notes are issued to the applicable Banks, in each case in principal amounts reflecting their respective Commitments, after giving effect to such Commitment Increase. In addition, within a reasonable period of time after the effective date of any Commitment Increase, Administrative Agent shall, and is hereby authorized and directed to, revise Schedule 1.1 to reflect such Commitment Increase and shall distribute such revised Schedule 1.1 to each of the Banks and Borrower, whereupon such revised Schedule 1.1 shall replace the old Schedule 1.1 and become part of this Agreement. On the first Domestic Business Day immediately following any such Commitment Increase, all outstanding Base Rate Loans shall be reallocated among the Banks (including any

newly added Bank(s)) in accordance with the Banks’ respective revised pro rata shares of such outstanding Base Rate Loans. Eurodollar Loans shall not be reallocated among the Banks prior to the expiration of the applicable Interest Periods in effect at the time of any such Commitment Increase.

Section 14.11 TEXAS LAW. THIS AGREEMENT, EACH NOTE AND THE OTHER LOAN PAPERS HAVE BEEN EXECUTED AND DELIVERED IN THE STATE OF TEXAS AND SHALL BE CONSTRUED IN ACCORDANCE WITH AND GOVERNED BY THE LAWS OF THE STATE OF TEXAS AND THE LAWS OF THE UNITED STATES OF AMERICA, EXCEPT TO THE EXTENT THAT THE LAWS OF ANY STATE IN WHICH ANY PROPERTY INTENDED AS SECURITY FOR THE OBLIGATIONS IS LOCATED NECESSARILY GOVERN (A) THE PERFECTION AND PRIORITY OF THE LIENS IN FAVOR OF ADMINISTRATIVE AGENT AND BANKS WITH RESPECT TO SUCH PROPERTY, AND (B) THE EXERCISE OF ANY REMEDIES (INCLUDING FORECLOSURE) WITH RESPECT TO SUCH PROPERTY.

Section 14.12 Consent to Jurisdiction; Waiver of Immunities.

(a) Borrower hereby irrevocably submits to the jurisdiction of any Texas State or Federal court sitting in the Northern District of Texas over any action or proceeding arising out of or relating to this Agreement or any other Loan Papers, and Borrower hereby irrevocably agrees that all claims in respect of such action or proceeding may be heard and determined in such Texas State or Federal court. Borrower irrevocably consents to the service of any and all process in any such action or proceeding by the delivery by Federal Express or other nationally recognized overnight delivery service of copies of such process to such Person at its address specified in Section 14.1. Borrower agrees that a final judgment on any such action or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by Law.

(b) Nothing in this Section 14.12 shall affect any right of Banks to serve legal process in any other manner permitted by Law or affect the right of any Bank to bring any action or proceeding against any Credit Party or their properties in the courts of any other jurisdictions.

(c) To the extent that Borrower has or hereafter may acquire any immunity from jurisdiction of any court or from any legal process (whether through service or notice, attachment prior to judgment, attachment in aid of execution, execution or otherwise) with respect to itself or its property, such Person hereby irrevocably waives such immunity in respect of its obligations under this Agreement and the other Loan Papers.

Section 14.13 Counterparts; Effectiveness. This Agreement may be signed in any number of counterparts, each of which shall be an original, with the same effect as if the signatures thereto and hereto were upon the same instrument. Subject to the terms and conditions herein set forth, this Agreement shall become effective when Administrative Agent shall have received counterparts hereof signed by all of the parties hereto or, in the case of any Bank as to which an executed counterpart shall not have been received, Administrative Agent shall have received telegraphic or other written confirmation from such Bank of execution of a counterpart hereof by such Bank.

Section 14.14 No Third Party Beneficiaries. Except for the provisions hereof inuring to the benefit of Agents not a party to this Agreement, it is expressly intended that there shall be no third party beneficiaries of the covenants, agreements, representations or warranties herein contained other than third party beneficiaries permitted pursuant to Section 14.10.

Section 14.15 COMPLETE AGREEMENT. THIS AGREEMENT AND THE OTHER LOAN PAPERS COLLECTIVELY REPRESENT THE FINAL AGREEMENT BY AND AMONG BANKS, AGENTS AND THE CREDIT PARTIES AND MAY NOT BE CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS, OR SUBSEQUENT ORAL AGREEMENTS OF BANKS, AGENTS, AND THE CREDIT PARTIES. THERE ARE NO UNWRITTEN ORAL AGREEMENTS AMONG BANKS, AGENTS, AND THE CREDIT PARTIES.

Section 14.16 WAIVER OF JURY TRIAL. BORROWER, ADMINISTRATIVE AGENT AND BANKS HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVE TRIAL BY JURY IN ANY LEGAL ACTION OR PROCEEDING RELATING TO THIS AGREEMENT OR ANY OF THE OTHER LOAN PAPERS AND FOR ANY COUNTERCLAIM THEREIN.

Section 14.17 Confidentiality. Administrative Agent and each Bank (each, a “Lending Party”) agrees to keep confidential any information furnished or made available to it by Borrower pursuant to this Agreement that is marked confidential; provided, that nothing herein shall prevent any Lending Party from disclosing such information (a) to any other Lending Party or any Affiliate of any Lending Party, or any officer, director, employee, agent, or advisor of any Lending Party or any Affiliate of any Lending Party, (b) to any other Person if reasonably incidental to the administration of the credit facility provided herein, (c) as required by any Law, rule or regulation, (d) upon the order of any court or administrative agency, (e) upon the request or demand of any regulatory agency or authority or self-regulatory body, (f) that is or becomes available to the public or that is or becomes available to any Lending Party other than as a result of a disclosure by any Lending Party prohibited by this Agreement, (g) in connection with any litigation to which such Lending Party or any of its affiliates may be a party relating to the Obligations or any Loan Paper, (h) to the extent necessary in connection with the exercise of any remedy under this Agreement or any other Loan Paper, and (i) subject to provisions substantially similar to those contained in this Section 14.17, to any actual or proposed participant or assignee.

Section 14.18 USA Patriot Act. Each Bank hereby notifies Borrower that, pursuant to the requirements of the USA Patriot Act (Title III of Pub. L. 107-56 (signed into law October 26, 2001)) (the “Act”), it is required to obtain, verify and record information that identifies Borrower, which information includes the name and address of Borrower and other information that will allow such Bank to identify Borrower in accordance with the Act.

IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be duly executed by their respective Authorized Officers on the day and year first above written.
