Amendment) constitute the legal, valid and binding obligations of the Borrower,
enforceable against it in accordance with their respective terms.

occurrence of the Effective Date.

5.  Miscellaneous.
    -------------

          (a)  The Borrower acknowledges and agrees that the execution and
delivery by the Agent and the Lenders of this Amendment shall not be deemed to
create a course of dealing or an obligation to execute similar waivers or
amendments under the same or similar circumstances in the future.

          (b)  This Amendment shall be binding upon and inure to the benefit of
the parties hereto and thereto and their respective successors and assigns.

          (c)  This Amendment shall be governed by and construed in accordance

shall retain all rights arising under Federal law.

          (d)  This Amendment may be executed in any number of counterparts,

such Lender or the Borrower, respectively, with the same force and effect as the
delivery of a hard copy original. Any failure by the Agent to receive the hard

party whose hard copy page was not received by the Agent.

parties hereto with reference to the matters discussed herein. This Amendment

prohibited by or invalid under any applicable law, such provision shall be

capacity as Agent), upon demand, for all reasonable costs and expenses
(including reasonable Attorney Costs) incurred by BofA (including in its
capacity as Agent) in connection with the development, preparation, negotiation,
execution and delivery of this Amendment.
