indirect cause of action or claim in connection with, this Agreement or any other of the Loan
Documents to which it is not a party. SECTION 7.7. TIME. Time is of the essence of each and every provision of this Agreement and
each other of the Loan Documents. SECTION 7.8. SEVERABILITY OF PROVISIONS. If any provision of this Agreement shall 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. SECTION 7.9. COUNTERPARTS. This Agreement may be executed in any number of counterparts, each
of which when executed and delivered shall be deemed to be an original, and all of which when taken
together shall constitute one and the same Agreement. SECTION 7.10. GOVERNING LAW. This Agreement shall be governed by and construed in accordance
with the laws of the State of Texas. SECTION 7.11. SAVINGS CLAUSE. It is the intention of the parties to comply strictly with
applicable usury laws. Accordingly, notwithstanding any provision to the contrary in the Loan
Documents, in no event shall any Loan Documents require the payment or permit the payment, taking,
reserving, receiving, collection or charging of any sums constituting interest under applicable
laws that exceed the maximum amount permitted by such laws, as the same may be amended or modified
from time to time (the Maximum Rate). If any such excess interest is called for, contracted for,
charged, taken, reserved or received in connection with any Loan Documents, or in any communication
by Bank or any other person to Borrower or any other person, or in the event that all or part of
the principal or interest hereof or thereof shall be prepaid or accelerated, so that under any of
such circumstances or under any other circumstance whatsoever the amount of interest contracted
for, charged, taken, reserved or - 11 -




---



##### 



received on the amount of principal actually outstanding from time to time under the Loan
Documents shall exceed the Maximum Rate, then in such event it is agreed that: (a) the provisions
of this paragraph shall govern and control; (b) neither Borrower nor any other person or entity now
or hereafter liable for the payment of any Loan Documents shall be obligated to pay the amount of
such interest to the extent it is in excess of the Maximum Rate; (c) any such excess interest which
is or has been received by Bank, notwithstanding this paragraph, shall be credited against the then
unpaid principal balance hereof or thereof, or if any of the Loan Documents has been or would be
paid in full by such credit, refunded to Borrower, and (d) the provisions of each of the Loan
Documents, and any other communication to Borrower, shall immediately be deemed reformed and such
excess interest reduced, without the necessity of executing any other document, to the Maximum
Rate. The right to accelerate the maturity of the Loan Documents does not include the right to
accelerate, collect or charge unearned interest, but only such interest that has otherwise accrued
as of the date of acceleration. Without limiting the foregoing, all calculations of the rate of
interest contracted for, charged, taken, reserved or received in connection with any of the Loan
Documents which are made for the purpose of determining whether such rate exceeds the Maximum Rate
shall be made to the extent permitted by applicable laws by amortizing, prorating, allocating and
spreading during the period of the full term of such Loan Documents, including all prior and
subsequent renewals and extensions hereof or thereof, all interest at any time contracted for,
charged, taken, reserved or received by Bank. The terms of this paragraph shall be deemed to be
incorporated into each of the other Loan Documents. To the extent that either Chapter 303 or 306, or both, of the Texas Finance Code apply in
determining the Maximum Rate, Bank hereby elects to determine the applicable rate ceiling by using
the weekly ceiling from time to time in effect, subject to Banks right subsequently to change such
method in accordance with applicable law, as the same may be amended or modified from time to time. SECTION 7.12. RIGHT OF SETOFF; DEPOSIT ACCOUNTS. Upon and after the occurrence of an Event of
Default, (a) Borrower hereby authorizes Bank, at any time and from time to time, without notice,
which is hereby expressly waived by each Borrower, and whether or not Bank shall have declared any
credit subject hereto to be due and payable in accordance with the terms hereof, to set off
against, and to appropriate and apply to the payment of, Borrowers obligations and liabilities
under the Loan Documents (whether matured or unmatured, fixed or contingent, liquidated or
unliquidated), any and all amounts owing by Bank to Borrower (whether payable in U.S. dollars or
any other currency, whether matured or unmatured, and in the case of deposits, whether general or
special (except trust and escrow accounts), time or demand and however evidenced), and (b) pending
any such action, to the extent necessary, to hold such amounts as collateral to secure such
obligations and liabilities and to return as unpaid for insufficient funds any and all checks and
other items drawn against any deposits so held as Bank, in its sole discretion, may elect. Borrower
hereby grants to Bank a security interest in all deposits and accounts maintained with Bank and
with any other financial institution to secure the payment of all obligations and liabilities of
Borrower to Bank under the Loan Documents. SECTION 7.13. BUSINESS PURPOSE. Borrower represents and warrants that each credit subject
hereto is for a business, commercial, investment, agricultural or other similar purpose and not
primarily for a personal, family or household use. - 12 -

SECTION 7.14. ARBITRATION. (a)       Arbitration. The parties hereto agree, upon demand by any party, to submit to
binding arbitration all claims, disputes and controversies between or among them (and their
respective employees, officers, directors, attorneys, and other agents), whether in tort, contract
or otherwise arising out of or relating to in any way (i) the loan and related Loan Documents which
are the subject of this Agreement and its negotiation, execution, collateralization,
administration, repayment, modification, extension, substitution, formation, inducement,
enforcement, default or termination; or (ii) requests for additional credit. (b)       Governing Rules. Any arbitration proceeding will (i) proceed in a location in
Texas selected by the American Arbitration Association (AAA); (ii) be governed by the Federal
Arbitration Act (Title 9 of the United States Code), notwithstanding any conflicting choice of law
provision in any of the documents between the parties; and (iii) be conducted by the AAA, or such
other administrator as the parties shall mutually agree upon, in accordance with the AAAs
commercial dispute resolution procedures, unless the claim or counterclaim is at least
$1,000,000.00 exclusive of claimed interest, arbitration fees and costs in which case the
arbitration shall be conducted in accordance with the AAAs optional procedures for large, complex
commercial disputes (the commercial dispute resolution procedures or the optional procedures for
large, complex commercial disputes to be referred to, as applicable, as the Rules). If there is
any inconsistency between the terms hereof and the Rules, the terms and procedures set forth herein
shall control. Any party who fails or refuses to submit to arbitration following a demand by any
other party shall bear all costs and expenses incurred by such other party in compelling
arbitration of any dispute. Nothing contained herein shall be deemed to be a waiver by any party
that is a bank of the protections afforded to it under 12 U.S.C. §91 or any similar applicable
state law. (c)       No Waiver of Provisional Remedies, Self-Help and Foreclosure. The arbitration
requirement does not limit the right of any party to (i) foreclose against real or personal
property collateral; (ii) exercise self-help remedies relating to collateral or proceeds of
collateral such as setoff or repossession; or (iii) obtain provisional or ancillary remedies such
as replevin, injunctive relief, attachment or the appointment of a receiver, before during or after
the pendency of any arbitration proceeding. This exclusion does not constitute a waiver of the
right or obligation of any party to submit any dispute to arbitration or reference hereunder,
including those arising from the exercise of the actions detailed in sections (i), (ii) and (iii)
of this paragraph. (d)       Arbitrator Qualifications and Powers. Any arbitration proceeding in which the
amount in controversy is $5,000,000.00 or less will be decided by a single arbitrator selected
according to the Rules, and who shall not render an award of greater than $5,000,000.00. Any
dispute in which the amount in controversy exceeds $5,000,000.00 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. The arbitrator will be a neutral attorney licensed
in the State of Texas with a minimum of ten years experience in the substantive law applicable to
the subject matter of the dispute to be arbitrated. The arbitrator will determine whether or not an
issue is arbitratable and will give effect to the statutes of limitation in determining any claim.
In any arbitration proceeding the arbitrator will decide (by documents only or with a hearing at
the arbitrators discretion) any pre-hearing motions which are similar to motions to dismiss for
failure to state a claim or motions for summary adjudication. The arbitrator shall resolve all
disputes in accordance with the substantive law of Texas and may grant any remedy or relief that a
court of such state could order or grant within the scope hereof and such ancillary relief as is
necessary - 13 -

to make effective any award. The arbitrator shall also have the power to award recovery of all
costs and fees, to impose sanctions and to take such other action as the arbitrator deems 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. Judgment upon the award rendered by the arbitrator may
be entered in any court having jurisdiction, The institution and maintenance of an action for
judicial relief or pursuit of a provisional or ancillary remedy shall not constitute a waiver of
the right of any party, including the plaintiff, to submit the controversy or claim to arbitration
if any other party contests such action for judicial relief. (e)       Discovery. In any arbitration proceeding discovery will be permitted in
accordance with the Rules. All discovery shall be expressly limited to matters directly relevant to
the dispute being arbitrated and must be completed no later than 20 days before the hearing date
and within 180 days of the filing of the dispute with the AAA. Any requests for an extension of the
discovery periods, or any discovery disputes, will be subject to final determination by the
arbitrator upon a showing that the request for discovery is essential for the partys presentation
and that no alternative means for obtaining information is available. (f)       Class Proceedings and Consolidations. The resolution of any dispute arising
pursuant to the terms of this Agreement shall be determined by a separate arbitration proceeding
and such dispute shall not be consolidated with other disputes or included in any class proceeding. (g)       Payment Of Arbitration Costs And Fees. The arbitrator shall award all costs and
expenses of the arbitration proceeding. (h)       Miscellaneous. 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 or by applicable law or
regulation. 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 Loan Documents or the
subject matter of the dispute shall control. This arbitration provision shall survive termination,
amendment or expiration of any of the Loan Documents or any relationship between the parties. NOTICE: THIS DOCUMENT AND ALL OTHER DOCUMENTS RELATING TO THE INDEBTEDNESS CONSTITUTE A WRITTEN
LOAN AGREEMENT WHICH REPRESENTS THE FINAL AGREEMENT BETWEEN THE PARTIES AND MAY NOT BE CONTRADICTED
BY EVIDENCE OF PRIOR, CONTEMPORANEOUS OR SUBSEQUENT ORAL AGREEMENTS OF THE PARTIES. THERE ARE NO
UNWRITTEN ORAL AGREEMENTS BETWEEN THE PARTIES RELATING TO THE INDEBTEDNESS. - 14 -
