         Borrower has requested  that,  among other  things,  Bank waive certain

principal reductions as well as other principal reductions due on the Loans, and
Bank has agreed to such waivers and amendments to the extent expressly set forth
herein.

         NOW, THEREFORE, in consideration of the promises herein contained,  and
for other good and valuable consideration,  the receipt and sufficiency of which
are  acknowledged  by the  Borrower,  the  Guarantors  and the  Bank,  and  each
intending to be legally bound hereby, the parties agree as follows:

I.       Specific Amendments to Loan Agreement.

         Article I is  hereby  amended  by adding  the  following  defined  term

         Section  2.03 is hereby  amended  by  replacing  the first  grammatical

         Million One Hundred Thousand and No/100 Dollars ($19,100,000.00), which
         shall thereafter decline in the amount of $400,000.00,  monthly (except
         for the months expressly  excluded,  below),  beginning on September 1,
         1997,  and  continuing  on the  first  day  of  each  successive  month
         thereafter;  provided, however, that such $400,000.00 monthly reduction
         in  Borrowing  Base I shall not occur  during the  months of  February,
         March and April 1998,  but shall then resume  effective on May 1, 1998,
         and continue  monthly  thereafter  until the effective date of the next

         monthly  reduction  in  Borrowing  Base II shall not occur  during  the
         months of February, March and April 1998.

         Section 5.37, as added to the Loan Agreement by the Sixth Amendment, is
hereby  amended by replacing the sum  A$3,000,000.00"  that appears in the third
line thereof with the sum  A$2,000,000.00,"  and by replacing the date AApril 1,
1998" that appears in the fourth line thereof with the date AApril 15, 1998.@

Term Note and the Mezzanine  Note, and the Guaranty of Ilyas  Chaudhary  relates
