     the execution of this Agreement, Borrower will execute one or more UCC
     financing statements and any similar statements as may be required by

     other reproduction of any financing statement for use as a financing
     statement. Borrower will reimburse Lender for all expenses for the
     perfection, termination, and the continuation of the perfection of
     Lender's security interest in the Collateral. Borrower promptly will
     notify Lender of any change in Borrower's name including any change to
     the assumed business names of Borrower. Borrower also promptly will

     principal governance office or should Borrower merge or consolidate with
     any other entity.

     COLLATERAL RECORDS. Borrower does now, and at all times hereafter shall,
     keep correct and accurate records of the Collateral, all of which
     records shall be available to Lender or Lender's representative upon
     demand for inspection and copying at any reasonable time. With respect

     or about Borrower by Lender in accordance with any court order, law or
     regulation and in response to credit inquiries concerning Borrower.

     NON-LIABILITY OF LENDER. The relationship between Borrower and Lender is
     a debtor and creditor relationship and not fiduciary in nature, nor is
     the relationship to be construed as creating any partnership or joint
     venture between Lender and Borrower. Borrower is execising its own
     judgment with respect to Borrower's business. All information supplied
     to Lender is for Lender's protection only and no other party is entitled

     inspect, supervise, or inform Borrower of any matter with respect to
     Borrower's business. Lender and Borrower intend that Lender may
     reasonably rely on all information supplied by Borrower to Lender,
     together with all representations and warranties given by Borrower to

     breach of this Agreement or the Related Documents by Lender and any
     other claim, cause of action or offset against Lender within thirty (30)

     claim, cause of action or offset. Borrower waives any claim, cause of
     action or offset for which notice is not given in accordance with this
     paragraph. Lender is entitled to rely on any failure to give such notice.

     BORROWER INDEMNIFICATION. Borrower shall indemnify and hold Lender
     harmless from and against all claims, costs, expenses, losses, damages,
     and liabilities of any kind, including but not limited to attorneys'
     fees and expenses, arising out of any matter relating directly or
     indirectly to the indebtedness, whether resulting from internal disputes
     of the Borrower, disputes between Borrower and any Guarantor, or whether
     involving any third parties, or out of any other matter whatsoever
     related to this Agreement or the Related Documents, but excluding any
     claim or liability which arises as a direct result of Lender's gross
     negligence or willful misconduct. This indemnity shall survive full
     repayment and satisfaction of the indebtedness and termination of this
     Agreement.

     COUNTERPARTS. This Agreement may be executed in multiple counterparts,
     each of which, when so executed, shall be deemed an original, but all
     such counterparts, taken together, shall constitute one and the same
     Agreement.

     COSTS AND EXPENSES. Borrower agrees to pay upon demand all of Lender's
     expenses, including without limitation reasonable attorneys' fees,
     incurred in connection with the preparation, execution, enforcement,
     modification and collection of this Agreement or in connection with the
     Loans made pursuant to this Agreement. Lender may pay someone else to
     help collect the Loans and to enforce this Agreement, and Borrower will
     pay the reasonable cost of such collection effort. This includes, subject
     to any limits under applicable law, Lender's attorneys' fees and Lender's
     legal expenses, whether or not there is a lawsuit, including attorneys'
     fees for bankruptcy proceedings (including efforts to modify or vacate
     any automatic stay or injunction), appeals, and any anticipated
     post-judgment collection services. Borrower also will pay any court
     costs, in addition to all other sums provided by law.

     NOTICES. All notices required to be given under this Agreement shall be
     given in writing, may be sent by telefacsimile (unless otherwise
     required by law), and shall be effective when actually delivered or when
     deposited with a nationally recognize overnight courier or deposited in
     the United States mail, first class, postage prepaid, addressed to the
     party to whom the notice is to be given at the address shown above. Any
     party may change its address for notices under this Agreement by giving
     formal written notice to the other parties, specifying that the purpose
     of the notice is to change the party's address. To the extent permitted
     by applicable law, if there is more than one Borrower, notice to any
     Borrower will constitute notice to all Borrowers. For notice purposes,
     Borrower will keep Lender informed at all times of Borrower's current
     address(es).

     SEVERABILITY. If a court of competent jurisdiction finds any provision
     of this Agreement to be invalid or unenforceable as to any person or
     circumstance, such finding shall not render that provision invalid or
     unenforceable as to any other persons or circumstances. If feasible, any
     such offending provision shall be deemed to be modified to be within the
     limits of enforceability or validly; however, if the offending provision
     cannot be so modified. It shall be stricken and all other provisions of
     this Agreement in all other respects shall remain valid and enforceable.

     SUBSIDIARIES AND AFFILIATES OF BORROWER. To the extent the context of
     any provisions of this Agreement makes it appropriate, including without
     limitation any representation, warranty or covenant, the word "Borrower"
     as used herein shall included all subsidiaries and affiliates of
     Borrower. Notwithstanding the foregoing however, under no circumstances
     shall this Agreement be construed to require Lender to make any Loan or
     other financial accommodation to any subsidiary or affiliate of Borrower.

     SUCCESSORS AND ASSIGNS. All covenants and agreements contained by or on
     behalf of Borrower shall bind its successors and assigns and shall inure
     to the benefit of Lender, its successors and assigns. Borrower shall not,
     however, have the right to assign its rights under this Agreement or any
     interest therein, without the prior written consent of Lender.

     SURVIVAL. All warranties, representations, and covenants made by
     Borrower in this Agreement or in any certificate or other instrument
     delivered by Borrower to Lender under this Agreement shall be considered
     to have been relied upon by Lender and will survive the making of the
     Loan and delivery to Lender of the Related Documents, regardless of any
     investigation made by Lender or on Lender's behalf.

     TIME IS OF THE ESSENCE. Time is of the essence in the performance of
     this Agreement.

     WAIVER. Lender shall not be deemed to have waived any rights under this
     Agreement unless such waiver is given in writing and signed by Lender.
     No delay or omission on the part of Lender in exercising any right shall
     operate as a waiver of such right or any other right. A waiver by Lender
     of a provision of this Agreement shall not prejudice or constitute a
     waiver of Lender's right otherwise to demand strict compliance with that
     provision or any other provision of this Agreement. No prior waiver by
     Lender, nor any course of dealing between Lender and Borrower, or
     between Lender and any Grantor, shall constitute a waiver of any of
     Lender's rights or of any obligations of Borrower or of any Grantor as
     to any future transactions. Whenever the consent of Lender is required
     under this Agreement, the granting of such consent by Lender in any
     instance shall not constitute continuing consent in subsequent instances
     where such consent is required, and in all cases such consent may be
     granted or withheld in the sole discretion of Lender.
