referred to herein collectively as the "Borrowers" and individually as a
"Borrower"), the banks named on the signature pages hereto (collectively, the
"Banks" and each individually, a "Bank"), and MASE WESTPAC LIMITED, NEW YORK
BRANCH, a New York State licensed branch of Mase Westpac Limited, an authorized
institution under the Banking Act of 1987 in England, as agent for the Banks
(in such capacity, together with its successors in such capacity, the "Agent").

                                    RECITALS

         WHEREAS, the Borrowers, certain banks and the Agent entered into a
Credit Agreement, dated as of January 25, 1993, as amended April 12, 1993 and
August 11, 1993 (such Credit Agreement as so amended, the "Credit Agreement"),
pursuant to which the banks party thereto agreed, subject to the terms and
conditions of the Credit Agreement, to provide financing to the Borrowers in an
aggregate amount not to exceed at any time the lesser of Twenty-Four Million
Dollars ($24,000,000), as such amount is reduced from time to time pursuant to
the terms of the Credit Agreement, or the Borrowing Base (as defined in the
Credit Agreement); and

         WHEREAS, the parties hereto desire to amend the Credit Agreement to
increase the maximum limit for borrowing and to make certain other amendments
to the Credit Agreement and other Loan Documents as provided herein;

                                   AGREEMENT

         NOW, THEREFORE, in consideration of the premises and the mutual
agreements contained herein, and for other good and valuable consideration
(including without limitation the consideration recited in the Credit
Agreement), the receipt and sufficiency of which are hereby acknowledged, the
parties hereto agree as follows:

         1. Definitions.  Capitalized terms used herein and not otherwise
defined herein shall have the meanings ascribed thereto in the Credit
Agreement.

         2. Addition of New Bank; Reallocation of Banks' Interests in Credit.
Each Bank shall be deemed a Bank (as defined in the Credit Agreement) for all
purposes under the Credit Agreement and the other Loan Documents, each as
amended hereby, to the extent of such Bank's interest as set forth opposite
such Bank's name on the





   2
signature pages hereto.  Each Bank shall have the same rights and benefits as
against the Borrowers and the same obligations to the Borrowers as it would
have had as if it were a Bank (as defined in the Credit Agreement) to the
extent of its interest as set forth opposite such Bank's name on the signature
pages hereto, or if such Bank was an original Bank under the Credit Agreement,
as if its interest under the Credit Agreement were the same as that set forth
opposite such Bank's name on the signature pages hereto.  All references in the
Credit Agreement and the other Loan Documents, each as amended hereby, to the
Banks shall as of the effective date hereof and thereafter be construed as a
reference to the Banks named on the signature pages hereto, each to the extent
of its interest as set forth opposite such Bank's name on the signature pages
hereto.  All references in the Credit Agreement and the other Loan Documents to
any Bank's pro rata share of the Commitment or of any Advances and all
references of similar import shall be deemed to be a reference to such Bank's
pro rata share as set forth opposite such Bank's name on the signature pages
hereto.
