         Amendment shall not be deemed (i) to create a course of dealing or
         otherwise obligate the Agents or the Lender to forbear or execute
         similar amendments under the same or similar circumstances in the
         future, or (ii) as a waiver by the Agents or the Lender of any
         covenant, condition, term or provision of the Financing Agreement or
         any of the other Credit Documents, and the failure of the Agents or the
         Lender to require strict performance by the Company or any other Credit
         Party of any provision thereof shall not waive, affect or diminish any
         right of the Agents or the Lender to thereafter demand strict

         rights granted under the Financing Agreement, the other Credit
         Documents and the Third Amendment. (b) The Company, Agents and Lender

         Company, the Agents and the Lender shall negotiate in good faith to
         adjust the provisions of Section 8.15 amended hereby in a manner
         reasonably consistent with the determination of the amendments
         contained herein to reflect the actual amount of the gross proceeds of
         such issuance.




                                      -4-
   5

         4.2      Full Force and Effect. As hereby modified, the Financing
         Agreement and each of the other Credit Documents shall remain in full
         force and effect and each is hereby ratified, approved and confirmed in
         all respects.

         4.3      Affirmation. The Company hereby affirms its obligations under
         Section 4 of the Financing Agreement and agrees to pay on demand all
         reasonable costs and expenses of the Agents and the Lender in
         connection with the preparation, execution and delivery of the Third
         Amendment and all instruments and documents delivered in connection
         herewith.

         4.4      Successors and Assigns. The Third Amendment shall be binding

         Agents and the Lender.

         4.5      Counterparts. The Third Amendment may be executed in any
         number of counterparts and by the different parties on separate
         counterparts, and each such counterpart shall be deemed to be an
         original, but all such counterparts shall together constitute but one
         and the same Third Amendment.

                                    * * * * *
