     4. Financial Reporting. Borrower hereby covenants and agrees to timely deliver to Lender the financial statements, reports and other information on Schedule 1 within (10) days of Lender’s request. All of such financial statements and reports shall be prepared in accordance with sound accounting principles and procedures, applied on a consistent basis in a manner and in form and substance reasonably satisfactory to Lender, and shall in all respects present a true, correct, complete and fair representation of the financial position of Borrower and Guarantor and shall be prepared and certified as to accuracy by a representative of Borrower and/or Guarantor, as applicable, reasonably acceptable to Lender.

     5. Negative Covenants. Borrower shall not do any of the following without Lender’s prior written consent:

business; (iv) purchase money indebtedness incurred for financing the acquisition of any additional equipment; and (v) additional indebtedness, in an aggregate principal amount not to exceed $8,000,000 outstanding at any time, which indebtedness shall be either unsecured or secured by assets of Borrower that do not constitute Collateral.

     (c) Directly or indirectly enter into or permit to exist any material transaction with any affiliate of Borrower, except for transactions that are in the ordinary course of Borrower’s business and upon fair and reasonable terms that are no less favorable to Borrower than would be obtained in an arm’s length transaction with a non-affiliated person. For purposes of this Section 5(c), Guarantor shall be deemed not to be an affiliate of Borrower.

     (d) Engage in any business other than the businesses currently engaged in by Borrower or reasonably related thereto.

Laws or commences or consents to the commencement of any proceeding under the Federal Bankruptcy Code or any other federal or state law, now or hereafter in effect, relating to the reorganization of Borrower or Guarantor or the arrangement or rearrangement or readjustment of the debts of Borrower or Guarantor or having the effect of enjoining or staying the exercise of rights or remedies by creditors, it being understood that the filing against Borrower or Guarantor of such a petition by a member, manager or officer of Borrower or Guarantor, as applicable, shall be deemed to be a filing with the consent of Borrower or Guarantor, as applicable, if there is an attachment or sequestration of or relating to any collateral or to any other substantial portion of any other assets of Borrower or Guarantor and the same is not promptly discharged (as used herein, “Debtor Relief Laws” means the Bankruptcy Code of the United States, and all other applicable liquidation, conservatorship, bankruptcy, moratorium, rearrangement, receivership, insolvency, reorganization, or similar debtor relief laws from time to time in effect affecting the rights of creditors generally); or

     (e) The nonpayment when due of any material indebtedness (which for purposes hereof shall be deemed to be indebtedness of at least $50,000) owed by Borrower or Guarantor (other than the Loan) and continuation of the same past any applicable grace period, or the occurrence of any event under any document evidencing, securing or executed in connection with any such indebtedness which could give the holder thereof the right to declare such indebtedness due prior to its scheduled maturity and the continuance of such event after all applicable notice and cure periods; or

     (f) The discovery by Lender that any representation or warranty made by Borrower or Guarantor to Lender in any of the Loan Documents or in any other certificate or document furnished to Lender in connection with the Loan or in furtherance of the requirements of this Loan Agreement or of any other Loan Documents shall be incorrect or misleading in any material respect; or

     (g) If Borrower or Guarantor shall cause, institute, or fail to contest any proceeding for the dissolution or termination of Borrower or Guarantor, as applicable; or

     (h) If Borrower or Guarantor ceases to do business or terminates its business as presently conducted for any reason whatsoever; or

     (i) If any one or more of the Loan Documents is terminated, revoked, or otherwise rendered void or unenforceable, in any case, without Lender’s prior written consent; or

     (o) An “Event of Default” as defined in either the Borrower Security Agreement or the Guarantor Security Agreement has occurred and is continuing; or

     (p) If there is (i) a material impairment in the perfection or priority of Lender’s security interest in the Collateral or in the value of such Collateral; or (ii) a material adverse change in the business, operations, or condition (financial or otherwise) of Borrower.

     7. Remedies. Upon the occurrence of an Event of Default, Lender shall have the immediate right, at the sole discretion of Lender and without notice or demand (i) to declare the entire unpaid balance of the Note and all accrued but unpaid interest at once immediately due and payable (and the same shall be at once immediately due and payable and the same may be collected forthwith), (ii) to foreclose and enforce all liens and security interests securing payment thereof, and (iii) to exercise any of Lender’s other rights, powers, recourses and remedies under the Note or any of the other Loan Documents, or at law or in equity. Except as may be prohibited by applicable law all of Lender’s rights and remedies shall be cumulative and may be exercised singularly or concurrently. Election by Lender to pursue any remedy shall not exclude pursuit of any other remedy, and an election to make expenditures or to take action to perform an obligation of any Obligated Party shall not affect Lender’s right to declare an Event of Default and to exercise its rights and remedies.

     8. Indemnity and Hold Harmless — Negligence. Borrower shall indemnify and defend Lender against, and shall hold Lender harmless from any and all losses, damages (whether general, punitive or otherwise), liabilities, claims, causes of action (whether legal, equitable or administrative), judgments, court costs and legal or other expenses (including attorneys’ fees) which Lender may suffer or incur as a direct or indirect consequence of (i) Lender’s performance under this Agreement or under any of the other Loan Documents, including without limitation Lender’s exercise or failure to exercise any rights, remedies or powers in connection with this Agreement or any of the other Loan Documents; (ii) Borrower’s failure to perform any of Borrower’s obligations as and when required by this Agreement or any of the other Loan Documents, including without limitation, any failure of any representation or warranty of Borrower to be true and correct in all material respects and any failure by Borrower to satisfy any condition; (iii) any claim or cause of action of any kind by any person or entity to the effect that Lender is in any way responsible or liable for any act or omission by Borrower, whether on account of any theory of derivative liability or otherwise; (iv) any claim or cause of action of any kind by any person or entity which would have the effect of denying Lender the full benefit or protection of any provision of this Agreement or any of the other Loan Documents; or (v) any proceeding or claim in any way relating to any collateral or the Loan Documents. Lender’s right of indemnity shall not be directly or indirectly limited, prejudiced, impaired or eliminated in any way by any finding or allegation that Lender’s conduct is active, passive or subject to any theory of any kind, character or nature for any act or omission by Borrower or any other person or entity except Lender. Notwithstanding the foregoing, although the above described indemnification extends to negligence, sole negligence, contractual comparative negligence and concurrent negligence of Lender, Borrower shall not be obligated to indemnify Lender with respect to any intentional tort, other willful misconduct or any act of gross negligence as to which Lender is determined by the judgment of a court of competent jurisdiction (sustained on appeal) to have committed.

     9. General Interest and Usury Provisions.

     (a) Savings Clause. It is expressly stipulated and agreed to be the intent of Borrower and 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 and the Related Indebtedness (as hereinafter defined) or applicable United States federal law to the extent that it permits 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 Borrower and 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 Lender’s exercise of the option to accelerate the maturity of the Note and/or the Related Indebtedness, or (iii) Borrower will have paid or Lender will have received by reason of any voluntary prepayment by Borrower of the Note and/or the Related Indebtedness, then it is Borrower’s and 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 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 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 laws, but so as to permit the recovery of the fullest amount otherwise called for hereunder and thereunder, provided, however, if the Note has been paid in full before the end of the stated term of the Note, then Borrower and Lender agree that Lender shall, with reasonable promptness after Lender discovers or is advised by Borrower that interest was received in an amount in excess of the Maximum Lawful Rate, either credit such excess interest against the Note and/or any Related Indebtedness then owing by Borrower to Lender and/or refund such excess interest to Borrower. Borrower hereby agrees that as a condition precedent to any claim seeking usury penalties against Lender, Borrower will provide written notice to Lender, advising Lender in reasonable detail of the nature and amount of the violation, and 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 Borrower or crediting such excess interest against the Note and/or the Related Indebtedness then owing by Borrower to Lender. All sums contracted for, charged, taken, reserved or received by 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, prorated, allocated 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 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. The terms and provisions of this paragraph

shall control and supersede every other term, covenant or provision contained herein, in any other Loan Document or in any other agreement between the Borrower and Lender.

     (b) 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 Related Indebtedness, 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 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, 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 Borrower as provided by such applicable law now or hereafter in effect.

     (c) Definitions.

          (i) As used herein, the term “Maximum Lawful Rate” shall mean the maximum lawful rate of interest which may be contracted for, charged, taken, received or reserved by Lender in accordance with the applicable laws of the State of Texas (or applicable United States federal law to the extent that such law permits Lender to contract for, charge, take, receive or reserve a greater amount of interest than under Texas law), taking into account all Charges made in connection with the transaction evidenced by the Note and the other Loan Documents.

          (ii) As used herein, the term “Charges” shall mean all fees, charges and/or any other things of value, if any, contracted for, charged, taken, received or reserved by Lender in connection with the transactions relating to the Note and the other Loan Documents, which are treated as interest under applicable law.

          (iii) As used herein, the term “Related Indebtedness” shall mean any and all indebtedness paid or payable by Borrower to Lender pursuant to the Loan Documents or any other communication or writing by or between Borrower and Lender related to the transaction or transactions that are the subject matter of the Loan Documents, except such indebtedness which has been paid or is payable by Borrower to Lender under the Note.

     10. Notices. Any notice or demand required hereunder shall be deemed to be delivered three (3) days after the same is deposited in the United States mail, postage prepaid, certified mail, return receipt requested, addressed to Borrower or Lender, as the case may be, at the address set out hereinbelow, or at such other address as such party may hereafter deliver in accordance herewith. Any other method of delivery or demand shall be effective only when actually received by the recipient thereof. If and when included within the term “Borrower” or “Lender” there are more than one person, all shall jointly arrange among themselves for their joint execution and delivery of a notice to the other specifying some person at some specific address for the receipt of all notices, demands, payments or other documents. All persons included within the terms “Borrower” or “Lender,” respectively, shall be bound by notices, demands, payments and documents given in accordance with the provisions of this paragraph to the same extent as if each had received such notice, demand, payment or document.
