Borrower and Lender further agree as follows:

A1.  INTEREST PAYMENTS AND OPTION GRANTS

     A1.1 PAYMENT OF INTEREST.  Lender hereby agrees to accept stock in lieu of
cash for interest payments due as follows:

          A1.1.1    For the time period of August 1998 through December 31,
1998; and

          A1.1.2    For the time period of January 1999 through June 30, 1999,
to be granted in advance based upon the parties' best estimates of the total
interest payments which will become due and payable through the time period
indicated.

          A1.1.3    For the time period after June 30, 1999, Borrower shall make
cash payments for interest due.

     A1.2 CALCULATION OF SHARES.  The number of shares granted to pay the
interest due shall be calculated by dividing the total interest due by the
average daily closing price as reported on the OTC:BB for the 10 trading days
immediately preceding the date of this Amendment.

     A1.3 ADDITIONAL GRANT OF OPTIONS.  As further consideration of Lender
accepting shares of common stock in lieu of interest payments, Borrower shall
grant to Lender an option to purchase an additional share of common stock for
every share received as payment for interest ("Interest Option").

          A1.3.1    The grant of Interest Options shall be made at the such time
as this Amendment is executed by all parties.

          A1.3.2    The Interest Options shall have an expiration date 10 years
from the date of grant and shall be exercisable at the average daily closing
price as reported on the OTC:BB for the 10 trading days immediately preceding
the date of this Amendment.

          A1.3.3    At the end of the period for which Lender agrees to accept
shares of common stock in lieu of interest, the number of estimated shares
granted and accompanying Interest Options shall be adjusted to reflect the
actual amount of accumulated interest; i.e., if Borrower over estimated the
interest, Lender agrees to forfeit the excess shares and Interest Options
granted, if Borrower under estimated, Borrower agrees to grant additional shares
and Interest Options to Lender.

to purchase an additional 600,000 shares of common stock at any time within 10
years of the date of grant at a price equal to the average daily closing price

of this Amendment.
