         2.1      Interest Expense Coverage Ratio (Section 7.4 of the Note 
                  Purchase Agreement.)

         The requirement in Section 7.4 of the Existing Note Purchase Agreement

1997 to and including June 30, 1998 to be not less than $4,000,000.

Purchase Agreement is such as to require a consent, approval or authorization

the part of the Company as a condition thereto.

4.       MISCELLANEOUS

         4.1.     Scope of Amendment.

         Except as expressly provided herein,

                  (a) no other terms and provisions of the Existing Note 
         Purchase Agreement are modified or changed by this Amendment,

                  (b) the Interest Expense Coverage Ratio and the Consolidated
         Net Worth requirements set forth in Section 7.4 and Section 7.5 of the
         Existing Note Purchase Agreement, for the periods other than those set
         forth in Section 2.1 and Section 2.2 hereof, shall remain as set forth
         in the Existing Note Purchase Agreement, and

                  (c) the terms and provisions of the Existing Note Purchase
         Agreement shall continue in full force and effect.

The Company hereby acknowledges, confirms, reaffirms and ratifies all of its
obligations and duties under the Amended Note Purchase Agreement and all
agreements related thereto. This Amendment is not a limitation on the ability of
the Noteholder to exercise any of its rights and remedies due to any Default or
Event of Default under the Amended Note Purchase Agreement.

         4.2      Payment of Consent Fee.

         The Company hereby agrees to pay to the Noteholder a quarterly consent
fee equal to one quarter of one percent (0.25%) of the outstanding principal
balance of the Notes as of the final day of the most recently ended fiscal
quarter prior to the due date of such payment (the "Consent Fee"). The Consent
Fee, if any, shall be due on or before January 31, 1998, April 30, 1998 and July
31, 1998 if the Company has failed to comply with the Interest Expense Coverage
Ratio and the Consolidated Net Worth requirements set forth in Sections 7.4 and
7.5, respectively, of the Original Note Purchase Agreement for the most recently
ended fiscal quarter prior to such date. Failure of the Company to pay the
Consent Fee when due shall result in an Event of Default under Section 9.1(b) of
the Existing Note Purchase Agreement.
