Section 2.1 Loans.

A. Revolving Credit Advances. Subject to the terms and conditions of this Agreement, the Lender agrees to make Revolving Credit Advances to the Borrower from time to time from the date hereof to and including the Revolving Credit Termination Date in an aggregate principal amount at any time outstanding up to but not exceeding the amount of the Revolving Credit Commitment, provided that the aggregate amount of all Revolving Credit Advances at any time outstanding shall not exceed the lesser of (i) the amount of the Revolving Credit Commitment minus all outstanding Letter of Credit Liabilities or (ii) the Borrowing Base minus all outstanding Letter of Credit Liabilities. Subject to the foregoing limitations, and the other terms and provisions of this Agreement, the Borrower may borrow, repay, and reborrow hereunder.

1. The Revolving Credit Note. The obligation of the Borrower to repay the Revolving Credit Advances and interest thereon shall be evidenced by the Revolving Credit Note executed by the Borrower, payable to the order of the Lender, in the principal amount of the Revolving Credit Commitment as originally in effect, and dated the date hereof.

2. Repayment of Revolving Credit Advances. The Borrower shall repay the unpaid principal amount of all Advances on the Revolving Credit Termination Date, unless sooner due by reason of acceleration by the Lender as provided in this Agreement.

3. Interest. The unpaid principal amount of the Revolving Credit Note shall, subject to the following sentence, bear interest as provided in the Revolving Credit Note. If at any time the rate of interest specified in the Revolving Credit Note would exceed the Maximum Lawful Rate but for the provisions thereof limiting interest to the Maximum Lawful Rate, then any subsequent reduction shall not reduce the rate of interest on the Revolving Credit Advances below the Maximum Lawful Rate until the aggregate amount of interest accrued on the Revolving Credit Advances equals the aggregate amount of interest which would have accrued on the Revolving Credit Advances if the interest rate had not been limited by the Maximum Lawful Rate. Accrued and unpaid interest on the Revolving Credit Advances shall be payable as provided in the Revolving Credit Note and on the Revolving Credit Termination Date.

LOAN AGREEMENT - Page 15

4. Borrowing Procedure. Except with respect to the credit sweep provisions of the Revolving Credit Note and requests for Advances made through the Lender’s internet request system, the Borrower shall give the Lender notice of each Revolving Credit Advance by means of an Advance Request Form containing the information required therein and delivered (by hand or by mechanically confirmed facsimile) to the Lender no later than 1:00 p.m. (Texas time) (i) for Prime Rate Loans, on the Business Day prior to the day on which the Revolving Credit Advance is desired to be funded, specifying the requested date of the Revolving Credit Advance, in a minimum amount of $100,000 plus integral multiples thereof, and (ii) for LIBOR Loans, three Business Days prior to the day on which the Revolving Credit Advance is desired to be funded, specifying the requested date of the Revolving Credit Advance, in a minimum amount of $250,000 plus integral multiples thereof. The Lender at its option may accept telephonic requests for such Revolving Credit Advances, provided that such acceptance shall not constitute a waiver of the Lender’s right to require delivery of an Advance Request Form in connection with subsequent Revolving Credit Advances. Any telephonic request for a Revolving Credit Advance by the Borrower shall be promptly confirmed by submission of a properly completed Advance Request Form to the Lender, but failure to deliver an Advance Request Form shall not be a defense to payment of the Revolving Credit Advance. The Lender shall have no liability to the Borrower for any loss or damage suffered by the Borrower as a result of the Lender’s honoring of any requests, execution of any instructions, authorizations or agreements or reliance on any reports communicated to it telephonically, by facsimile or electronically and purporting to have been sent to the Lender by the Borrower and the Lender shall have no duty to verify the origin of any such communication or the identity or authority of the Person sending it.

Accrued and unpaid interest on the Term Note Advances shall be payable as provided in the Term Note and on the Term Loan Termination Date.

Section 2.2 General Provisions Regarding Interest; Etc.

A. Any outstanding principal of any Advance and (to the fullest extent permitted by law) any other amount payable by the Borrower under this Agreement or any other Loan Document that is not paid in full when due (whether at stated maturity, by acceleration, or otherwise) shall bear interest at the Default Interest Rate for the period from and including the due date thereof to but excluding the date the same is paid in full. Additionally, upon the occurrence of an Event of Default (and from the date of such occurrence) all outstanding and unpaid principal amounts of all of the Obligations shall, to the extent permitted by law, bear interest at the Default Interest Rate until such time as the Lender shall waive in writing the application of the Default Interest Rate to such Event of Default situation.

B. Computation of Interest. Interest on the Advances and all other amounts payable by the Borrower hereunder shall be computed on the basis of a year of 360 days and the actual number of days elapsed (including the first day but excluding the last day) unless such calculation would result in a usurious rate, in which case interest shall be calculated on the basis of a year of 365 or 366 days, as the case may be.

Section 2.3 Unused Facility Fee. The Borrower agrees to pay to the Lender an unused facility fee on the daily average unused amount of the Revolving Credit Commitment for the period from and including the date of this Agreement to and including the Termination Date, at the rate of one-quarter of one percent (.25%) per annum based on a 360 day year and the actual number of days elapsed.

LOAN AGREEMENT - Page 17

Section 2.4 Use of Proceeds.

Each payment by the Lender pursuant to a drawing under a Letter of Credit is due and payable ON DEMAND, and at the sole option of the Lender, can be charged by the Lender as (and will be deemed to be) a Revolving Credit Advance by the Lender to the Borrower under the Revolving Credit Note and this Agreement as of the day and time such payment is made by the Lender and in the amount of such payment.

B. Obligations Absolute. The obligation of the Borrower to reimburse the Lender for each drawing under each Letter of Credit shall be absolute, unconditional and irrevocable, and shall be paid strictly in accordance with the terms of this Agreement under all circumstances, including the following:

1. any lack of validity or enforceability of such Letter of Credit, this Agreement, or any other agreement or instrument relating thereto;

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

LOAN AGREEMENT - Page 18

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

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

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

C. Role of Lender. The Borrower agrees that, in paying any drawing under a Letter of Credit, the Lender shall not have any responsibility to obtain any document (other than any sight draft, certificates and documents expressly required by the Letter of Credit) or to ascertain or inquire as to the validity or accuracy of any such document or the authority of the Person executing or delivering any such document. The Borrower hereby assumes all risks of the acts or omissions of any beneficiary or transferee with respect to its use of any Letter of Credit; provided, however, that this assumption is not intended to, and shall not, preclude the Borrower’s pursuing such rights and remedies as it may have against the beneficiary or transferee at law or under any other agreement. None of the Lender, any of its Affiliates, any of the respective officers, directors, employees, agents or attorneys-in-fact of the Lender and its Affiliates, nor any of the respective correspondents, participants or assignees of the Lender shall be liable or responsible for any of the matters described in clauses (1) through (4) of Section 2.5.B; provided, however, that anything in such clauses to the contrary notwithstanding, the Borrower may have a claim against the Lender, and the Lender may be liable to the Borrower, to the extent, but only to the extent, of any direct, as opposed to consequential or exemplary, damages suffered by the Borrower which the Borrower proves were caused by the Lender’s willful misconduct or gross negligence or the Lender’s willful failure to pay under any Letter of Credit after the presentation to it by the beneficiary of a sight draft and certificate(s) strictly complying with the terms and conditions of a Letter of

LOAN AGREEMENT - Page 19

Credit. In furtherance and not in limitation of the foregoing, the Lender may accept documents that appear on their face to be in order, without responsibility for further investigation, and the Lender shall not be responsible for the validity or sufficiency of any instrument transferring or assigning or purporting to transfer or assign a Letter of Credit or the rights or benefits thereunder or proceeds thereof, in whole or in part, which may prove to be invalid or ineffective for any reason.

D. Cash Collateral. Upon the request of the Lender, (i) if the Lender has honored any full or partial drawing request under any Letter of Credit and such drawing has not been reimbursed on the applicable honor date or converted to a Revolving Credit Advance, or (ii) if, as of the Revolving Credit Termination Date, any Letter of Credit may for any reason remain outstanding and partially or wholly undrawn, the Borrower shall immediately Cash Collateralize the then outstanding amount of all Letter of Credit obligations (in an amount equal to such outstanding amount determined as of the applicable honor date or the Letter of Credit expiration date, as the case may be). For purposes hereof, “Cash Collateralize” means to pledge and deposit with or deliver to the Lender, as collateral for the Letter of Credit obligations, cash or deposit account balances pursuant to documentation in form and substance satisfactory to the Lender. Derivatives of such term have corresponding meanings. The Borrower hereby grants to the Lender a security interest in all such cash, deposit accounts and all balances therein and all proceeds of the foregoing. Cash Collateral shall be maintained in a blocked, non-interest bearing deposit account at the Lender.

E. Applicability of ISP98. Unless otherwise expressly agreed by the Lender and the Borrower when a Letter of Credit is issued, the rules of the “International Standby Practices 1998” published by the Institute of International Banking Law & Practice (or such later version thereof as may be in effect at the time of issuance) shall apply to each Letter of Credit.

The Borrower shall pay to the Lender, an amount equal to two and twenty-five one hundredths percent (2.25%) per annum on the daily average undrawn amount of the Letter of Credit Liability from and including the date of this Agreement to and including the Revolving Credit Termination Date.

The Borrower hereby irrevocably (a) submits to the nonexclusive jurisdiction of such courts, and (b) waives any objection it may now or hereafter have as to the venue of any such action or proceeding brought in any such court or that any such court is an inconvenient forum. The Borrower agrees that service of process upon it may be made by certified or registered mail, return receipt requested, at its address specified or determined in accordance with the provisions of Section 11.12. Nothing herein or in any of the other Loan Documents shall affect the right of the Lender to serve process in any other manner permitted by law or shall limit the right of the Lender to bring any action or proceeding against the Borrower or with respect to any of its property in courts in other jurisdictions.

Each actual or proposed participant or assignee, as the case may be, shall be entitled to receive all information received by the Lender regarding the Borrower and its Subsidiaries, including, without limitation, information required to be disclosed to a participant or assignee pursuant to Banking Circular 181 (Rev., August 2, 1984), issued by the Comptroller of the Currency (whether the actual or proposed participant or assignee is subject to the circular or not).

Section 11.21 Arbitration.

A. Upon the demand of any party, any dispute under this Agreement or the Loan Documents shall be resolved by binding arbitration (except as set forth in Section 11.20.E. below) in accordance with the terms of this Agreement or the other Loan Documents. Any party may by summary proceedings bring an action in court to compel arbitration of a Dispute. Any party who fails or refuses to submit to arbitration following a lawful demand by any other party shall bear all costs and expenses incurred by such other party in compelling arbitration of any Dispute.

B. Arbitration proceedings shall be administered by the American Arbitration Association (“AAA”) or such other administrator as the parties shall mutually agree upon in accordance with the AAA Commercial Arbitration Rules. All Disputes submitted to arbitration shall be resolved in accordance with the Federal Arbitration Act (Title 9 of the United States Code), notwithstanding any conflicting choice of law provision in any of the foregoing documents. The arbitration shall be conducted at a location in Dallas County, Texas selected by the AAA or other administrator. If there is any inconsistency between the terms hereof and any such rules, the terms and procedures set forth herein shall control.. All statutes of limitation applicable to any Dispute shall apply to any arbitration proceeding. All discovery activities shall be expressly limited to matters directly relevant to the Dispute being arbitrated. Judgment upon any award rendered in an arbitration may be entered in any court having jurisdiction; provided however, that nothing contained herein shall be deemed to be a waiver by any party that is a bank of the protections afforded to it under Section 91 of Title 12 of the United States Code or any similar applicable state law.

C. No provision hereof shall limit the right of any party to exercise self-help remedies such as setoff, foreclosure against or sale of any real or personal property collateral or security, or to obtain provisional or ancillary remedies,

LOAN AGREEMENT - Page 46

including without limitation, injunctive relief, sequestration, attachment, garnishment or the appointment of a receiver from a court of competent jurisdiction before, after or during the pendency of any arbitration or other proceeding. The exercise of any such remedy shall not waive the right of any party to compel arbitration hereunder.

D. Arbitrators must be active members of the Texas State Bar with expertise in the substantive law applicable to the subject matter of the Dispute. Arbitrators are empowered to resolve Disputes by summary rulings in response to motions filed prior to the final arbitration hearing. Arbitrators (i) shall resolve all Disputes in accordance with the substantive law of the State of Texas, (ii) may grant any remedy or relief that a court of the State of Texas could order or grant within the scope hereof and such ancillary relief as is necessary to make effective any award, and (iii) shall have the power to award recovery of all costs and fees, to impose sanctions and to take such other actions as they deem necessary to the same extent a judge could pursuant to the Federal Rules of Civil Procedure, the Texas Rules of Civil Procedure or other applicable law. Any Dispute in which the amount in controversy is $5,000,000 or less shall be decided by a single arbitrator who shall not render an award of greater than $5,000,000 (including damages, costs, fees and expenses). By submission to a single arbitrator, each party expressly waives any right or claim to recover more than $5,000,000. Any Dispute in which the amount in controversy exceeds $5,000,000 shall be decided by majority vote of a panel of three arbitrators; provided however, that all three arbitrators must actively participate in all hearings and deliberations.

E. Notwithstanding anything herein to the contrary, in any arbitration in which the amount in controversy exceeds $25,000,000, the arbitrators shall be required to make specific, written findings of fact and conclusions of law. In such arbitrations (i) the arbitrators shall not have the power to make any award which is not supported by substantial evidence or which is based on legal error, (ii) an award shall not be binding upon the parties unless the findings of fact are supported by substantial evidence and the conclusions of law are not erroneous under the substantive law of the State of Texas, and (iii) the parties shall have in addition to the grounds referred to in the Federal Arbitration Act for vacating, modifying or correcting an award the right to judicial review of (1) whether the findings of fact rendered by the arbitrators are supported by substantial evidence, and (2) whether the conclusions of law are erroneous under the substantive law of the State of Texas. Judgment confirming an award in such a proceeding may be entered only if a court determines the award is supported by substantial evidence and not based on legal error under the substantive law of the State of Texas.

F. To the maximum extent practicable, the AAA, the arbitrators and the parties shall take all action required to conclude any arbitration proceeding within 180 days of the filing of the Dispute with the AAA. No arbitrator or other party to an arbitration proceeding may disclose the existence, content or results thereof, except for disclosures of information by a party required in the ordinary course of its business, by applicable law or regulation, or to the extent necessary to exercise any judicial review rights set forth herein. If more than one agreement for

LOAN AGREEMENT - Page 47

arbitration by or between the parties potentially applies to a Dispute, the arbitration provision most directly related to the foregoing documents or the subject matter of the Dispute shall control. If any provision of this Agreement shall be held to be prohibited by or invalid under applicable law, such provision shall be ineffective only to the extent of such prohibition or invalidity, without invalidating the remainder of such provision or any remaining provisions of this Agreement. This arbitration provision shall survive termination, amendment or expiration of any of the foregoing documents or any relationship between the parties.

G. Lender and Borrower hereby agree to keep all Disputes and arbitration proceedings strictly confidential, provided, however, that Lender and Borrower may disclose such confidential information as is necessary in any litigation between Lender and Borrower or as required by applicable law and, on a confidential basis, to accountants, attorneys and other consultants in the ordinary course of business.

Section 11.22 Additional Interest Provision. It is expressly stipulated and agreed to be the intent of the Borrower and the Lender at all times to comply strictly with the applicable Texas law governing the maximum rate or amount of interest payable on the indebtedness evidenced by any Note, any Loan Document, and the Related Indebtedness (or applicable United States federal law to the extent that it permits the Lender to contract for, charge, take, reserve or receive a greater amount of interest than under Texas law). If the applicable law is ever judicially interpreted so as to render usurious any amount (i) contracted for, charged, taken, reserved or received pursuant to any Note, any of the other Loan Documents or any other communication or writing by or between the Borrower and the Lender related to the transaction or transactions that are the subject matter of the Loan Documents, (ii) contracted for, charged, taken, reserved or received by reason of the Lender’s exercise of the option to accelerate the maturity of any Note and/or any and all indebtedness paid or payable by the Borrower to the Lender pursuant to any Loan Document other than any Note (such other indebtedness being referred to in this Section as the “Related Indebtedness”), or (iii) the Borrower will have paid or the Lender will have received by reason of any voluntary prepayment by the Borrower of any Note and/or the Related Indebtedness, then it is the Borrower’s and the Lender’s express intent that all amounts charged in excess of the Maximum Lawful Rate shall be automatically canceled, ab initio, and all amounts in excess of the Maximum Lawful Rate theretofore collected by the Lender shall be credited on the principal balance of any Note and/or the Related Indebtedness (or, if any Note and all Related Indebtedness have been or would thereby be paid in full, refunded to the Borrower), and the provisions of any Note and the other Loan Documents shall immediately be deemed reformed and the amounts thereafter collectible hereunder and thereunder reduced, without the necessity of the execution of any new document, so as to comply with the applicable law, but so as to permit the recovery of the fullest amount otherwise called for hereunder and thereunder; provided, however, if any Note has been paid in full before the end of the stated term of any such Note, then the Borrower and the Lender agree that the Lender shall, with reasonable promptness after the Lender discovers or is advised by the Borrower that interest was received in an amount in excess of the Maximum Lawful Rate, either refund such excess interest to the Borrower and/or credit such excess interest against such Note and/or any Related Indebtedness then owing by the Borrower to the Lender. The Borrower hereby agrees that as a condition precedent to any claim seeking usury penalties against the Lender, the

LOAN AGREEMENT - Page 48

Borrower will provide written notice to the Lender, advising the Lender in reasonable detail of the nature and amount of the violation, and the Lender shall have sixty (60) days after receipt of such notice in which to correct such usury violation, if any, by either refunding such excess interest to the Borrower or crediting such excess interest against the Note to which the alleged violation relates and/or the Related Indebtedness then owing by the Borrower to the Lender. All sums contracted for, charged, taken, reserved or received by the Lender for the use, forbearance or detention of any debt evidenced by any Note and/or the Related Indebtedness shall, to the extent permitted by applicable law, be amortized or spread, using the actuarial method, throughout the stated term of such Note and/or the Related Indebtedness (including any and all renewal and extension periods) until payment in full so that the rate or amount of interest on account of any Note and/or the Related Indebtedness does not exceed the Maximum Lawful Rate from time to time in effect and applicable to such Note and/or the Related Indebtedness for so long as debt is outstanding. In no event shall the provisions of Chapter 346 of the Texas Finance Code (which regulates certain revolving credit loan accounts and revolving triparty accounts) apply to this Note and/or any of the Related Indebtedness. Notwithstanding anything to the contrary contained herein or in any of the other Loan Documents, it is not the intention of the Lender to accelerate the maturity of any interest that has not accrued at the time of such acceleration or to collect unearned interest at the time of such acceleration.

Section 11.23 Ceiling Election. To the extent that Lender is relying on Chapter 303 of the Texas Finance Code to determine the Maximum Lawful Rate payable on any such Note and/or any other portion of the Indebtedness, the Lender will utilize the weekly ceiling from time to time in effect as provided in such Chapter 303, as amended. To the extent United States federal law permits the Lender to contract for, charge, take, receive or reserve a greater amount of interest than under Texas law, Lender will rely on United States federal law instead of such Chapter 303 for the purpose of determining the Maximum Lawful Rate. Additionally, to the extent permitted by applicable law now or hereafter in effect, the Lender may, at its option and from time to time, utilize any other method of establishing the Maximum Lawful Rate under such Chapter 303 or under other applicable law by giving notice, if required, to the Borrower as provided by applicable law now or hereafter in effect.
