requires such qualification or authorization and the failure to so qualify would
have a Materially Adverse Effect.

power, and has taken all necessary action to authorize it, to execute, deliver
and perform this Amendment and each other agreement contemplated hereby to which
it is a party in accordance with their respective terms. This Amendment and each
other agreement contemplated hereby to which it is a party have been duly
executed and delivered by the duly authorized officers of the Borrower and each
is, or each when executed and delivered in accordance with this Amendment will
be, a legal, valid and binding obligation of the Borrower, enforceable in
accordance with its terms.

         (c)      Compliance of Agreements with Laws. The execution, delivery
and performance of this Amendment and each other agreement contemplated hereby
to which the Borrower is a party in accordance with their respective terms do
not and will not, by the passage of time, the giving of notice or otherwise,

                  (i)      require any Governmental Approvals or violate any
         Applicable Law relating to the Borrower,

                  (iii)    conflict with, result in a breach of or constitute a

         of the Borrower, any material provisions of any indenture, agreement or
         other instrument to which the Borrower is a party or by which it or its
         property may be bound or any Governmental Approvals relating to the
         Borrower, which conflict, breach or default could have a Materially
         Adverse Effect, or

                  (iv)     result in or require the creation or imposition of
         any Lien upon or with respect to any property now owned or hereafter
         acquired by the Borrower, other than the Security Interest.

         SECTION 5.        Expenses. The Borrower agrees to pay or reimburse on
demand all costs and expenses, including, without limitation, reasonable fees
and disbursements of counsel, incurred by the Agent in connection with the
negotiation, preparation, execution and delivery of the Amendment.

in accordance with, and governed by the laws of, the State of Georgia.

         SECTION 7.        Counterparts. This Amendment may be executed in any
number of counterparts and by different parties hereto in separate counterparts,
each of which when so executed shall be deemed to be an original and shall be
binding upon all parties and their respective successors and assigns and all of
which taken together shall constitute one and the same agreement.
