    Section
3.       New Lenders and Reallocation

Commitments and (i) to, among other things, allow each of Bank of America, N.A.,
Compass Bank and U.S. Bank National Association to become a party to the Credit
Agreement as Lender, (each a “New Lender”) by
acquiring an interest in the total Commitments, (ii) to allow Guaranty Bank, FSB
(“Guaranty
Bank”) and The Bank of Tokyo – Mitsubishi UFJ, Ltd., New York Branch (as
successor by merger to UFJ Bank Limited) (each, an “Exiting Lender”) to
assign and be released from their respective Commitment and (iii) to allow
Guaranty Bank to resign as co-agent.  The Administrative Agent and the
Borrower hereby consent to such reallocation and each New Lender’s acquisition
of an interest in the total Commitments, each Exiting Lenders assignment and
release from their respective Commitment and to Guaranty Bank's resignation as a
co-agent.  On the Fourth Amendment Effective Date and after giving
effect to such reallocation of the total Commitments, the Commitment of each
Lender shall be as set forth on Annex I of this Amendment and the Commitment of
each Exiting Lender shall be zero ($0.00).  With respect to such
reallocation, each New Lender shall be deemed to have acquired the Commitment
allocated to it from each of the other Lenders, including the Exiting Lenders,
pursuant to the terms of the Assignment and Assumption Agreement attached as
Exhibit G to the Credit Agreement as if such New Lender and the other Lenders
had executed an Assignment and Assumption Agreement with respect to such
allocation.
