A. Advances. Subject to the terms and conditions of this Agreement, the Lender agrees to make one or more Advances to the Borrower from time to time from the date hereof to and including the Termination Date in an aggregate principal amount at any time outstanding up to but not exceeding the amount of the Commitment, provided that the aggregate amount of all Advances at any time outstanding shall not exceed the (A) lesser of (i) the amount of the Commitment or (ii) the Borrowing Base, minus (B) the Guidance Line Borrowing Base Usage.

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

LOAN AGREEMENT		Page 8

4. Interest. The unpaid principal amount of the Note shall, subject to the following sentence, bear interest as provided in the Note. If at any time the rate of interest specified in the 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 Advances below the Maximum Lawful Rate until the aggregate amount of interest accrued on the Advances equals the aggregate amount of interest which would have accrued on the Advances if the interest rate had not been limited by the Maximum Lawful Rate. Accrued and unpaid interest on the Advances shall be payable as provided in the Note and on the Termination Date.

5. Borrowing Procedure. The Borrower shall give the Lender notice of each 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 3:00 p.m. (Texas time) on the day on which the Advance is desired to be funded. Advances shall be in a minimum amount of $50,000.00. The Lender at its option may accept telephonic requests for such 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 Advances. Any telephonic request for a 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 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.

Lender may, in its sole and absolute discretion, enter into foreign currency forward contracts with Borrower from time to time from the date hereof to December 19, 2013 up to the aggregate amount of $7,500,000.00; provided, however, (i) that the Guidance Line Borrowing Base Usage shall not exceed the Borrowing Base minus all outstanding Advances, and (ii) the term of any such foreign currency forward contract cannot exceed one (1) year and cannot extend past the Termination Date. No provision in this Agreement or any other Loan Document shall in any way obligate Lender to enter into any foreign currency forward contract with Borrower. Borrower shall execute any and all documents, instruments and agreements requested by Lender in connection with such forward contracts and such items shall be deemed to be Loan Documents for all purposes.

Section 2.2 General Provisions Regarding Interest; Etc.

A. Default Interest. 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. Interest payable at the Default Interest Rate shall be payable from time to time on demand.

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 Commitment for the period from and including the date of this Agreement to and including the Termination Date, at the rate set forth below per annum based on a 360 day year and the actual number of days elapsed based on the respective total deposits maintained by Borrower with Lender. For the purpose of calculating the commitment fee hereunder, the Commitment shall be deemed utilized by the amount of all outstanding Advances. The unused facility fee shall be payable in arrears on the first day of each calendar quarter commencing January 1, 2009, based on the average of Borrower’s deposits maintained with Lender during the immediately preceding calendar quarter (rounded up to the next highest dollar) and on the Termination Date. Borrower shall use its deposit balance with Lender to offset any treasury management fees charged by Lender. The initial Unused Facility Fee for the calendar quarter ending December 31, 2008 shall be .75%.

LOAN AGREEMENT		Page 24

Section 11.5 Lender Not Fiduciary. The relationship between the Borrower and the Lender is solely that of debtor and creditor, and the Lender has no fiduciary or other special relationship with the Borrower, and no term or condition of any of the Loan Documents shall be construed so as to deem the relationship between the Borrower and the Lender to be other than that of debtor and creditor.

Section 11.6 Omitted.

Section 11.7 No Waiver; Cumulative Remedies. No failure on the part of the Lender to exercise and no delay in exercising, and no course of dealing with respect to, any right, power, or privilege under this Agreement shall operate as a waiver thereof, nor shall any single or partial exercise of any right, power, or privilege under this Agreement preclude any other or further exercise thereof or the exercise of any other right, power, or privilege. The rights and remedies provided for in this Agreement and the other Loan Documents are cumulative and not exclusive of any rights and remedies provided by law.

Section 11.8 Successors and Assigns.

Section 11.9 Survival. All representations and warranties made in this Agreement or any other Loan Document or in any document, statement, or certificate furnished in connection with this Agreement shall survive the execution and delivery of this Agreement and the other Loan Documents, and no investigation by the Lender or any closing shall affect the representations and warranties or the right of the Lender to rely upon them. Without prejudice to the survival of any other obligation of the Borrower hereunder, the obligations of the Borrower under subsections 11.1, and 11.2 shall survive repayment of the Note and termination of the Commitment.

All such other notices and other communications shall be deemed to have been given or made upon the earliest to occur of (i) actual receipt by the intended recipient or (ii) (A) if delivered by hand or courier, when signed for by the designated recipient; (B) if delivered by mail, four business days after deposit in the mail, postage prepaid; (C) if delivered by facsimile when sent and receipt has been confirmed by telephone; and (D) if delivered by electronic mail (which form of delivery is subject to the provisions of the last sentence below) when delivered; provided, however, that notices and other communications pursuant to Article II shall not be effective until actually received by the Lender.

Section 11.12 Governing Law; Venue; Service of Process. This Agreement shall be governed by and construed in accordance with the laws of the State of Texas and the applicable laws of the United States of America. This Agreement has been entered into in Dallas County, Texas, and it shall be performable for all purposes in Dallas County, Texas. Any action or proceeding against the Borrower under or in connection with any of the Loan Documents may be brought in any state or federal court in Dallas County, Texas. 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. Any action or proceeding by the Borrower against the Lender shall be brought only in a court located in Dallas County, Texas.

Section 11.13 Counterparts. This Agreement may be executed in one or more counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument.

Section 11.14 Severability. Any provision of this Agreement held by a court of competent jurisdiction to be invalid or unenforceable shall not impair or invalidate the remainder of this Agreement and the effect thereof shall be confined to the provision held to be invalid or illegal.

Section 11.15 Headings. The headings, captions, and arrangements used in this Agreement are for convenience only and shall not affect the interpretation of this Agreement.

Section 11.16 Participations; Etc. The Lender shall have the right at any time and from time to time to grant participations in, and sell and transfer, the Obligations and any Loan Documents.

LOAN AGREEMENT		Page 26

Section 11.17 Construction. The Borrower and the Lender acknowledge that each of them has had the benefit of legal counsel of its own choice and has been afforded an opportunity to review this Agreement and the other Loan Documents with its legal counsel and that this Agreement and the other Loan Documents shall be construed as if jointly drafted by the Borrower and the Lender.

Section 11.18 Independence of Covenants. All covenants hereunder shall be given independent effect so that if a particular action or condition is not permitted by any of such covenants, the fact that it would be permitted by an exception to, or be otherwise within the limitations of, another covenant shall not avoid the occurrence of a Default if such action is taken or such condition exists.

Section 11.19 WAIVER OF JURY TRIAL. TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, BORROWER HEREBY IRREVOCABLY AND EXPRESSLY WAIVES ALL RIGHT TO A TRIAL BY JURY IN ANY ACTION, PROCEEDING, OR COUNTERCLAIM (WHETHER BASED UPON CONTRACT, TORT, OR OTHERWISE) ARISING OUT OF OR RELATING TO ANY OF THE LOAN DOCUMENTS OR THE TRANSACTIONS CONTEMPLATED THEREBY OR THE ACTIONS OF LENDER IN THE NEGOTIATION, ADMINISTRATION, OR ENFORCEMENT THEREOF.

Section 11.20 Arbitration.

A. Upon the demand of any party, any dispute 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 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.

LOAN AGREEMENT		Page 27

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, 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.

LOAN AGREEMENT		Page 28

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 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 11.21 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 the 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 the 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 the Note and/or any and all indebtedness paid or payable by the Borrower to the Lender pursuant to any Loan Document other than the 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 the 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 the Note and/or the Related Indebtedness (or, if the Note and all Related Indebtedness have been or would thereby be paid in full, refunded to the Borrower), and the provisions of the 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

LOAN AGREEMENT		Page 29

and thereunder; provided, however, if the Note has been paid in full before the end of the stated term of any the 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 the 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 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 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 the 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 the 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 the Note and/or the Related Indebtedness does not exceed the Maximum Lawful Rate from time to time in effect and applicable to the 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 the 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 11.22 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 the 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.
