(a) It is understood that the cost to the Bank of making or maintaining any of the Advances may fluctuate as a result of the applicability of, or changes in, reserve requirements imposed by the Board of Governors of the Federal Reserve System.

(b) Notwithstanding any other provision herein, if after the date of this Agreement the introduction of any applicable law or regulation or any change in applicable law or regulation or in the interpretation or administration thereof by any governmental authority charged with the interpretation or administration thereof, or compliance by the Bank with any applicable guideline or request from any central bank or governmental authority (whether or not having the force of law) (i) shall change the basis of taxation of payments to the Bank of the principal of or interest on any Advance made by the Bank or any other fees or amounts payable hereunder, other than (x) taxes imposed on the overall net income or franchise taxes with respect to the Bank or its lending office by the jurisdiction in which the Bank or its lending office has its principal office or by any political subdivision or taxing authority therein (or any tax which is enacted or adopted by such jurisdiction, political subdivision or taxing authority as a direct substitute for any such taxes) or (y) any tax, assessment or other governmental charge that would not have been imposed but for the failure of the Bank to comply with any certification, information, documentation or other reporting requirement, or (ii) shall impose, modify or deem applicable any reserve, special deposit or similar requirement against assets of, deposits with or for the account of, or credit extended by the Bank, and the result of any of the foregoing shall be to increase the cost to the Bank of maintaining its Commitment or to reduce the amount of any sum received or receivable by the Bank hereunder (whether of principal, interest or otherwise) in respect thereof by an amount deemed in good faith by the Bank to be material, then the Borrower shall pay to the Bank such additional amount as will compensate the Bank for such increase or reduction upon demand by the Bank. Notwithstanding the foregoing, in no event shall the Bank be permitted to receive any compensation hereunder constituting interest in excess of the Highest Lawful Rate.

(c) If the Bank shall have determined in good faith that the adoption of any applicable law, rule, regulation or guideline regarding capital adequacy, or any change therein, 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 the Bank (or any lending office of the Bank) with any request or directive regarding capital adequacy (whether or not having the force of law) of any such authority, central bank or comparable agency (including any capital adequacy guidelines under consideration as of the date of this Agreement by the Board of Governors of the Federal Reserve System and the Comptroller of the Currency) (except any such adoption or change reflected in the Prime Rate), has or would have the effect of reducing the rate of return on the Bank’s capital or any corporation controlling the Bank’s capital as a consequence of its obligations hereunder to a level below that which the Bank could have achieved but for such adoption, change or compliance (taking into consideration the Bank’s policies with respect to capital adequacy) by an amount deemed by the Bank to be material, then from time to time the Borrower shall pay to the Bank such additional amount or amounts as will compensate the Bank for such reduction upon demand by the Bank.

-17-

(d) If the Bank seeks compensation under this Agreement it will notify the Borrower of any event occurring after the date of this Agreement which will entitle the Bank to compensation pursuant to this Section, as promptly as practicable, and in any event within 180 days after it becomes aware thereof and determines to request compensation. A certificate of the Bank setting forth in reasonable detail (i) such amount or amounts as shall be necessary to compensate the Bank as specified in paragraph (a) or (b) above, as the case may be, and (ii) the calculation of such amount or amounts shall be delivered to the Borrower and shall be prima facie evidence. The Borrower shall pay to the Bank the amount shown as due on any such certificate within ten days after its receipt of the same.

(e) Failure on the part of the Bank to demand compensation for any increased costs or reduction in amounts received or receivable or reduction in return on capital with respect to any Advance shall not constitute a waiver of the Bank’s rights to demand compensation for any increased costs or reduction in amounts received or receivable or reduction in return on capital with respect to such Advance, provided that Borrower’s obligation to pay the Bank shall be limited to the increased costs or reduced amount that is attributable to the period commencing 180 days prior to the date on which the Bank gives the Borrower notice under subsection (d) hereof. The protection of this Section shall be available to the Bank regardless of any possible contention of invalidity or inapplicability of law, regulation or condition that has been imposed.

SECTION 3.11 Indemnity.

A certificate of the Bank setting forth any amount or amounts which the Bank is entitled to receive pursuant to this Section shall be delivered to the Borrower and shall be conclusive, if made in good faith, absent demonstrable error. The Borrower shall pay to the Bank the amount shown as due on any certificate within 30 days after its receipt of the same. Notwithstanding the foregoing, in no event shall the Bank be permitted to receive any compensation hereunder constituting interest in excess of the Highest Lawful Rate. Without prejudice to the survival of any other obligations of the Borrower hereunder, the obligations of the Borrower as to any claim under this Section shall survive the termination of this Agreement, the payment or assignment of any of the Notes or any combination of the foregoing provided notice of such claim shall have been given to the Borrower within 180 days after such termination or assignment.

Subject to the terms and conditions set forth herein, the Borrower may request the issuance of Letters of Credit for its own account, in a form reasonably acceptable to the Bank, at any time and from time to time prior to the Working Capital Loan Maturity Date. In the event of any inconsistency between the terms and conditions of this Agreement and the terms and conditions of any form of letter of credit application or other agreement submitted by the Borrower to, or entered into by the Borrower with, the Bank relating to any Letter of Credit, the terms and conditions of this Agreement shall control.

SECTION 4.02 Notice of Issuance, Amendment, Renewal, Extension; Certain Conditions. To request the issuance of a Letter of Credit (or the amendment, renewal or extension of an outstanding Letter of Credit), the Borrower shall hand deliver or telecopy (or transmit by electronic communication, if arrangements for doing so have been approved by the Bank) to the Bank (reasonably in advance of the requested date of issuance, amendment, renewal or extension) a notice requesting the issuance of a Letter of Credit, or identifying the Letter of Credit to be amended, renewed or extended, and specifying the date of issuance, amendment, renewal or extension (which shall be a Business Day), the date on which such Letter of Credit is to expire (which shall comply with Section 4.03), the amount (in Dollars) of such Letter of Credit, the name and address of the beneficiary thereof and such other information as shall be necessary to prepare, amend, renew or extend such Letter of Credit. If requested by the Bank, the Borrower also shall submit a letter of credit application on the Bank’s standard form in connection with any request for a Letter of Credit. A Letter of Credit shall be issued, amended, renewed or extended only if (and upon issuance, amendment, renewal or extension of each Letter of Credit the Borrower shall be deemed to represent and warrant that), after giving effect to such issuance, amendment, renewal or extension (i) the LC Exposure shall not exceed $500,000 and (ii) the total Working Capital Exposures shall not exceed the total Working Capital Loan Commitment.

SECTION 4.03 Expiration Date.

-19-

SECTION 4.04 Reimbursement. If the Bank makes any LC Disbursement in respect of a Letter of Credit, the Borrower shall reimburse such LC Disbursement by paying to the Bank an amount equal to such LC Disbursement not later than 12:00 noon, Houston, Texas time, on (i) the Business Day that the Borrower receives notice of such LC Disbursement, if such notice is received prior to 11:00 a.m., Houston, Texas time, on the day of receipt, or (ii) the Business Day immediately following the day that the Borrower receives such notice, if such notice is not received prior to such time on the day of receipt; provided, however, that, if no Default has occurred and is continuing, the Borrower may, subject to the conditions to borrowing set forth herein, request in accordance with Section 2.01(a) an Advance to finance such reimbursement and, to the extent so financed, the Borrower’s obligation to make such payment shall be discharged and replaced by the resulting Working Capital Advance.

SECTION 4.05 Obligations Absolute. The Borrower’s obligation to reimburse LC Disbursements as provided in Section 4.04 shall be absolute, unconditional and irrevocable, and shall be performed strictly in accordance with the terms of this Agreement under any and all circumstances whatsoever and irrespective of (i) any lack of validity or enforceability of any Letter of Credit or this Agreement, or any term or provision therein, (ii) any draft or other document presented under a Letter of Credit proving to be forged, fraudulent or invalid in any respect or any statement therein being untrue or inaccurate in any respect, (iii) payment by the Bank under a Letter of Credit against presentation of a draft or other document that does not comply with the terms of such Letter of Credit, or (iv) any other event or circumstance whatsoever, whether or not similar to any of the foregoing, that might, but for the provisions of this Section, constitute a legal or equitable discharge of, or provide a right of setoff against, the Borrower’s obligations hereunder. Neither the Bank nor any of its Affiliates shall have any liability or responsibility by reason of or in connection with the issuance or transfer of any Letter of Credit or any payment or failure to make any payment thereunder (irrespective of any of the circumstances referred to in the preceding sentence), or any error, omission, interruption, loss or delay in transmission or delivery of any draft, notice or other communication under or relating to any Letter of Credit (including any document required to make a drawing thereunder), any error in interpretation of technical terms or any consequence arising from causes beyond the control of the Bank; provided, however, that the foregoing shall not be construed to excuse the Bank from liability to the Borrower to the extent of any direct damages (as opposed to consequential damages, claims in respect of which are hereby waived by the Borrower to the extent permitted by applicable law) suffered by the Borrower that are caused by the Bank’s failure to exercise care when determining whether drafts and other documents presented under a Letter of Credit comply with the terms thereof. In the absence of gross negligence or willful misconduct on the part of the Bank (as finally determined by a court of competent jurisdiction), the Bank shall be deemed to have exercised care in each such determination. In furtherance of the foregoing and without limiting the generality thereof, with respect to documents presented that appear on their face to be in substantial compliance with the terms of a Letter of Credit, the Bank may, in its sole discretion, either accept and make payment upon such documents without responsibility for further investigation, regardless of any notice or information to the contrary, or refuse to accept and make payment upon such documents if such documents are not in strict compliance with the terms of such Letter of Credit.

SECTION 4.06 Disbursement Procedures. The Bank shall, promptly following its receipt thereof, examine all documents purporting to represent a demand for payment under a Letter of Credit. The Bank shall promptly notify the Borrower by telephone (confirmed by telecopy) of such demand for payment and whether the Bank has made or will make an LC Disbursement thereunder; provided, however, that any failure to give or delay in giving such notice shall not relieve the Borrower of its obligation to reimburse the Bank with respect to any such LC Disbursement.

-20-

SECTION 4.07 Interim Interest. If the Bank shall make any LC Disbursement, then, unless the Borrower shall reimburse such LC Disbursement in full on the date such LC Disbursement is made, the unpaid amount thereof shall bear interest, for each day from and including the date such LC Disbursement is made to but excluding the date that the Borrower reimburses such LC Disbursement, at the rate per annum then applicable to the Working Capital Loan; provided, however, that, if the Borrower fails to reimburse such LC Disbursement when due pursuant to Section 4.04, then Section 3.02(d) shall apply.

SECTION 4.08 Cash Collateralization. If any Event of Default shall occur and be continuing, on the Business Day that the Borrower receives notice from the Bank demanding the deposit of cash collateral pursuant to this paragraph, the Borrower shall deposit in an account with the Bank, in the name of the Bank, an amount in cash equal to 105% of the LC Exposure as of such date plus any accrued and unpaid interest thereon; provided, however, that the obligation to deposit such cash collateral shall become effective immediately, and such deposit shall become immediately due and payable, without demand or other notice of any kind, upon the occurrence of any Event of Default with respect to the Borrower described in clause (d) or (e) of Section 9.01. Such deposit shall be held by the Bank as collateral for the payment and performance of the obligations of the Borrower under this Agreement. The Bank shall have exclusive dominion and control, including the exclusive right of withdrawal, over such account. Other than any interest earned on the investment of such deposits, which investments shall be made at the option and sole discretion of the Bank and at the Borrower’s risk and expense, such deposits shall not bear interest. Interest or profits, if any, on such investments shall accumulate in such account. The Bank shall apply moneys in such account to reimburse the itself for LC Disbursements for which it has not been reimbursed and, to the extent not so applied, shall be held for the satisfaction of the reimbursement obligations of the Borrower for the LC Exposure at such time or, if the maturity of the Loans has been accelerated, be applied to satisfy other obligations of the Borrower under this Agreement. If the Borrower is required to provide an amount of cash collateral hereunder as a result of the occurrence of an Event of Default, such amount (to the extent not applied as aforesaid) shall be returned to the Borrower within three Business Days after all Events of Default have been cured or waived.

SECTION 10.06 Interest. Anything in this agreement or the other Loan Documents to the contrary notwithstanding, the Borrower shall never be required to pay unearned interest on any Note and shall never be required to pay interest on such Note at a rate in excess of the Highest Lawful Rate, and if the effective rate of interest that would otherwise be payable under this Agreement, the other Loan Documents and such Note would exceed the Highest Lawful Rate, or if the holder of such Note shall receive any unearned interest or shall receive monies that are deemed to constitute interest that would increase the effective rate of interest payable by the Borrower under this Agreement and the other Loan Documents to a rate in excess of the Highest Lawful Rate, then (a) the amount of interest that would otherwise be payable by the Borrower under this Agreement, such Note and the other Loan Documents shall be reduced to the highest nonusurious amount allowed under applicable law; and (b) any unearned interest paid by the Borrower or any interest paid by the Borrower in excess of the Highest Lawful Rate shall be credited on the principal of such Note and to the extent any funds remain, refunded to the Borrower. Without limitation of the foregoing, all calculations of the rate of interest contracted for, charged or received by the Bank under the Note, or under this Agreement, are made for the purpose of determining whether such rate exceeds the Highest Lawful Rate applicable to the Bank (such Highest Lawful Rate being the Bank’s “Maximum Permissible Rate”) and shall be made, to the extent permitted by usury laws applicable to the Bank (now or hereafter enacted), by amortizing, prorating and spreading in equal parts during the period of the full stated term of the Advances evidenced by said Note all interest at any time contracted for, charged or received by the Bank in connection therewith. If at any time and from time to time (i) the amount of interest payable to the Bank on any date shall be computed at the Bank’s Maximum Permissible Rate pursuant to this Section and (ii) in respect of any subsequent interest computation period the amount of interest otherwise payable to the Bank would be less than the amount of interest payable to the Bank computed at the Bank’s Maximum Permissible Rate, then the amount of interest payable to the Bank in respect of such subsequent interest computation period shall continue to be computed at the Bank’s Maximum Permissible Rate until the total amount of interest payable to the Bank shall equal the total amount of interest that would have been payable to the Bank if the total amount of interest had been computed without giving effect to this Section.

SECTION 10.07 Indemnification. The Borrower shall indemnify the Bank, the Affiliates of the Bank, and their respective directors, officers, employees, agents, representatives and attorneys of each of them (the “Indemnified Parties”) from, and hold each of them harmless against, any and all liabilities, obligations, losses, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind or nature whatsoever to which any of them may become subject arising out of or based on the Loan Documents but excluding any such liabilities, obligations, losses, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind or nature whatsoever incurred by reason of the gross negligence or willful misconduct of the Indemnified Party. The obligations of the Borrower under this Section shall survive the termination of this Agreement and/or the payment or assignment of the Notes. IT IS THE EXPRESS INTENTION OF THE BORROWER THAT THE INDEMNIFIED PARTIES SHALL BE INDEMNIFIED AND HELD HARMLESS AGAINST ANY AND ALL LIABILITIES, OBLIGATIONS, LOSSES, PENALTIES, ACTIONS, JUDGMENTS, SUITS, COSTS, EXPENSES OR DISBURSEMENTS OF ANY KIND OR NATURE WHATSOEVER ARISING OUT OF THE SOLE OR CONTRIBUTORY NEGLIGENCE OF THE INDEMNIFIED PARTY OR EACH OF THEM.

SECTION 10.11 Assignment.

SECTION 10.12 Separability. Should any clause, sentence, paragraph or Section of this Agreement be judicially declared to be invalid, unenforceable or void, such decision shall not have the effect of invalidating or voiding the remainder of this Agreement, and the parties hereto agree that the part or parts of this Agreement so held to be invalid, unenforceable or void shall be deemed to have been stricken herefrom and the remainder shall have the same force and effectiveness as if such part or parts had never been included herein.

SECTION 10.13 Limitation by Law. All rights, remedies and powers provided in this Agreement and the other Loan Documents may be exercised only to the extent that the exercise thereof does not violate any applicable provision of law, and all the provisions of this Agreement and the other Loan Documents are intended to be subject to all applicable mandatory provisions of law that may be controlling and to be limited to the extent necessary so that they will not render this Agreement or any other Loan Document invalid, unenforceable, in whole or in part, or not entitled to be recorded, registered or filed under the provisions of any applicable law.

(b) The arbitration shall be conducted in Houston, Texas and administered by AAA, who shall appoint an arbitrator; if AAA is unable or legally precluded from administering the arbitration, then the Judicial Arbitration and Mediation Services, Inc. shall serve. All arbitration hearings shall be commenced within 90 days of the demand for arbitration; further, the arbitrator shall only, upon a showing of cause, be permitted to extend the commencement of such hearing for up to an additional 60 days.

(c) Nothing in this Agreement shall be deemed to (i) limit the applicability of any otherwise applicable statutes of limitation or repose and any waivers contained in this Agreement or the Credit Documents; or (ii) be a waiver by the Bank of the protection afforded to it by 12 ▇.▇.▇. §▇▇ or any substantially equivalent state law; or (iii) limit the rights of the Bank hereto (A) to exercise self help remedies such as (but not limited to) set-off, or (B) to foreclose against any real or personal property collateral, or (C) to obtain from a court provisional or ancillary remedies such as (but not limited to) injunctive relief, writ of possession or the appointment of a receiver.
