Documents have been duly authorized by all necessary corporate action, and each
has been duly executed and delivered by the Company and each is valid, binding

Liens. Neither the execution and delivery of this Agreement and Related
Documents, nor the consummation of the transactions contemplated hereby or
thereby nor compliance with the terms hereof or thereof under the circumstances
contemplated hereby or thereby will conflict with, are prohibited by or will
contravene, violate or constitute a breach of or a default under the Amended and
Restated Certificate of Incorporation or By-Laws of the Company or constitute on
the part of the Company a material breach of or a material default under any
agreement or other instrument to which the Company is a party or any existing
law, administrative regulation, or, to its knowledge, any court order or consent
decree to which the Company is subject, or by which any of its properties is
bound.

         Section 8.4. Effect of Delay and Waivers. No delay or omission to
exercise any right or power accruing upon any default, omission or failure of
performance hereunder shall impair any such right or power or shall be construed
to be a waiver thereof, but any such right and power may be exercised from time
to time and as often as may be deemed expedient. In order to entitle Guarantor
to exercise any remedy now or hereafter existing at law or in equity or by
statute, it shall not be necessary to give any notice, other than such notice as
may be herein expressly required. In the event any provision contained in this
Agreement should be breached by any party and thereafter waived by the other
party so empowered to act, such waiver shall be limited to the particular breach
so waived and shall not be deemed to waive any other breach hereunder. No
waiver, amendment, release or modification of this Agreement shall be
established by conduct, custom or course of dealing, but solely by an instrument
in writing duly executed by the parties thereunto duly authorized by this
Agreement.

         Section 8.5. Counterparts. This Agreement may be executed
simultaneously in counterparts, each of which shall be deemed an original, but
both of which together shall constitute one and the same instrument.

         Section 8.6. Severability. The invalidity or unenforceability of any
one or more phrases, sentences, clauses or Sections contained in this Agreement
shall not affect the validity or enforceability of the remaining portions of
this Agreement, or any part thereof. In particular, this section means (among
other things) that the Company does not agree or intend to pay, and Guarantor
does not agree to contract for, charge, collect, take, reserve or receive
(collectively referred to herein as "charge or collect"), any amount in the
nature of interest or in the nature of a fee for anything construed to be a
loan, which would in any way or event (including demand, prepayment, or
acceleration) cause Guarantor to charge or collect more for entering into this
Agreement than the maximum amount Guarantor would be permitted to charge or
collect by federal law or the laws of the State of Texas. Any such excess
interest or unauthorized fee shall, instead or anything stated to the contrary,
be applied first to reduce the principal balance of the loan, if any, and when
the principal has been paid in full, refunded to the Company.

         Section 8.7. Governing Law and Jurisdiction. This Agreement shall be
governed by and construed in accordance with the laws of the State of Texas.

         Section 8.8 Prior Agreements. This Agreement supercedes the Original
Reimbursement Agreement and the October Reimbursement Agreement.
