issuance of a payment blockage notice by the Administrative Agent or any of the
other Lenders to the Borrower and/or to the Trustee under the Subordinated Notes
Indenture (as provided for in Section 5.5 of the Subordinated Notes Indenture)

Agreement or any of the other the Loan Papers, or the exercise of any right or
remedy otherwise available at law or in equity, and shall not be prohibited by
any provision of this Agreement.

         SECTION 3.        OTHER AGREEMENTS. To induce the Administrative Agent
and Lenders to enter into this Agreement, the Borrower hereby agrees as follows:

         Loan B, 4.00% per annum for LIBOR Advances and 3.00% per annum for Base

         from the Effective Date until the Termination Date, while interest will
         accrue at the rates described above with respect to the Applicable

         (a)      RATIFICATION AND CONFIRMATION OF LOAN PAPERS. Except as
specifically modified by this Agreement, the terms, provisions, conditions and
covenants of the Credit Agreement and the other Loan Papers remain in full
force and effect and are hereby ratified and confirmed, and the execution,
delivery and performance of this Agreement shall not in any manner operate as a
waiver of, consent to or amendment of any other term, provision, condition or
covenant of the Credit Agreement or any other Loan Paper. The provisions of
this Agreement are intended to supplement the Credit Agreement, however, to the
extent that any provision of this Agreement directly conflicts with the Credit
Agreement, the provision in this Agreement shall control. Without limiting the
generality of the foregoing, the forbearance provided by this Agreement shall
not be deemed to constitute a waiver of compliance or consent to noncompliance
by any of the Loan Parties with respect to any other term, provision, condition
or covenant of the Credit Agreement or other Loan Papers.

         (b)      AFFIRMATION OF GUARANTEES. Notwithstanding that such consent
is not required thereunder, the Parent, the Borrower and the Subsidiaries of
the Parent and the Borrower hereby consent to the execution and delivery of
this Agreement by the parties hereto and reaffirm their respective obligations
under each of their respective Guaranties.

         (c)      LIENS. The Parent, the Borrower and the Subsidiaries agree
hereby that all Liens, security interests, assignments, superior titles,
rights, remedies, powers, equities and priorities securing the Obligations
including but not limited to those under the Loan Papers are hereby ratified
and confirmed as valid, subsisting and continuing to secure the Obligations,
and this Agreement shall not affect the priority of such Liens. Nothing in this
Agreement shall in any manner diminish, impair or extinguish any of the Liens
securing the Obligations, the Guaranties, or the other Loan Papers or be
construed as a novation in any respect.

         (d)      HEADINGS. Section and subsection headings in this Agreement
are included herein for convenience of reference only and shall not constitute
a part of this Agreement for any other purpose or be given any substantive
effect.

         (e)      APPLICABLE LAW. THIS AGREEMENT SHALL BE GOVERNED BY, AND
SHALL BE CONSTRUED AND INTERPRETED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF
TEXAS, WITHOUT REGARD TO CONFLICTS OF LAW PRINCIPLES.

         (f)      COUNTERPARTS AND EFFECTIVE DATE. This Agreement may be
executed in any number of counterparts and by different parties hereto in
separate counterparts, each of which when so executed and delivered shall be
deemed an original, but all such counterparts together shall constitute but one
and the same instrument; signature pages may be detached from multiple separate
counterparts and attached to a single counterpart so that all signature pages
are physically attached to the same document. The Effective Date shall occur
when the conditions precedent set forth in Section 10 of this Agreement have
been satisfied in full (the "Effective Date").

         (g)      SEVERABILITY.     If any provision of this Agreement is held
to be illegal, invalid, or unenforceable under present or future Laws during
the term thereof, such provision shall be fully severable, the appropriate
provision shall be construed and enforced as if such illegal, invalid, or
unenforceable provision had never comprised a part thereof, and the remaining
provisions thereof shall remain in full force and effect and shall not be
affected by the illegal, invalid, or unenforceable provision or by its severance
therefrom. Furthermore, in lieu of such illegal, invalid, or unenforceable
provision there shall be added automatically as a part of this Agreement a
legal, valid, and enforceable provision as similar in terms to the illegal,
invalid, or unenforceable provision as may be possible. Provisions in this
Agreement that may be approved by Majority Lenders as provided in the Credit
Agreement shall become effective upon receipt of the signature pages of
Majority Lenders and provisions in this Agreement that must be approved by all
Lenders as provided in the Credit Agreement shall become effective upon receipt
of the signature pages of all Lenders.

         (h)      AMENDMENT AND RESTATEMENT.     This Agreement is an amendment
and restatement of the Forbearance Agreement executed by Borrower and each
other Loan Party for the benefit of the Administrative Agent for itself and the
Lenders. This Agreement supersedes the Forbearance Agreement, as amended, in
its entirety.

         (i)      FINAL AGREEMENT.     THIS AGREEMENT, TOGETHER WITH THE CREDIT
AGREEMENT AND OTHER LOAN PAPERS, 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.
