the purchase of capital expenditures in excess of $8,000,000 in any
fiscal year shall be accompanied by a detailed list and explanation

Certification") or (ii) June 1, 1996.

      (b)  OPIC hereby waives (i) noncompliance by the Company with
Section 2.07(ii) of the Finance Agreement, as amended hereby, and (ii)

                                ARTICLE III

                         COVENANTS AND AGREEMENTS

      SECTION 3.01. REINSTATEMENT OF MANDATORY PREPAYMENT REQUIREMENT.
If by June 1, 1996, the Company has not provided to OPIC a Favorable
Reserve Certification, then, on the next succeeding Principal Payment
Date, the Company shall prepay the OPIC Debt in an amount (the
"Required Prepayment Amount") equal to the sum of (i) the aggregate amount
that, but for the waiver provided in Section 2.01 hereof, would have
been due to OPIC during the Waiver Period, plus (ii) any amounts then due
to OPIC in accordance with Section 2.07 of the Finance Agreement, as amended,

                                      3



      SECTION 4.02. NO IMPLICIT WAIVER. The waivers set forth in this
Amendment shall not be deemed a waiver by OPIC of any other provision of
the Finance Agreement, and no course of dealing and no failure or
delay by OPIC in exercising any right, power or remedy under the
Finance Agreement shall operate as a waiver thereof or otherwise
prejudice OPIC's rights, powers or remedies.

      SECTION 4.03. GOVERNING LAW. This Amendment shall be construed and
enforced in accordance with the laws of the State of New York of the
United States of America without regard to its conflict of laws provisions.
