     7. The Options are exercisable as follows: (a) one-third of the total
Options are exercisable on the earlier of September 13, 2006 or the first day
after the Closing Price of the Company's common stock has equaled or exceeded
a price equal to 150% of the Exercise Price for 20 consecutive trading days;
(b) one-third of the total Options are exercisable on the earlier of September

price equal to 175% of the Closing Price for 20 consecutive trading days; and
(c) one-third of the total Options are exercisable on the earlier of September
13, 2006 or the first day after the Closing Price has equaled or exceeded a
price equal to 200% of the Closing Price for 20 consecutive trading days.

     8. All Options that are not exercised on or before September 12, 2009,
expire and will no longer be exercisable. "Closing Price" means (a) the
closing price of the common stock if the common stock is then traded on a
national securities exchange, (ii) the last sale price if the common stock is
then quoted on the NASDAQ National Market System or (iii) the average of the
closing representative bid and asked prices of the common stock as reported on
NASDAQ on the date as of which fair market value is being determined.

     9. The options may be exercised by delivery to the Company of the option
price by check (bank check, certified check or personal check) in the amount
of the Shares being purchased.

     10. At any time or times after September 22, 2005, holders holding at
least two thirds of the options may make written request to the Company to
register all or a part of the option shares having a reasonably anticipated
aggregate offering price, net of underwriting discounts and commissions, that
exceeds $5,000,000. Also, if the Company determines to register any of its
securities either for its own account or the account of a security holder or
holders, other than a registration relating solely to employee benefit plans,
or a registration relating solely to a Rule 145 transaction, or a registration
on any registration form which does not permit secondary sales, the Company
may include the option shares in such registration.

                          Item 8.01. Other Events

Effective September 24, 2004, the Company agreed to extend until October 24,
2004, the Closing Date, for the Manufacturing and Distribution License
Agreement and related agreements (collectively, the "Agreement") between the
Company and Liberty Circle S.A., a Panamanian corporation ("Liberty Circle").
Under the terms of the Agreement, Liberty Circle was to have made an initial
payment of $3,125,000 of the approximately $6.5 million transaction by
September 3, 2004.

The Company had granted Liberty Circle an extension to September 24, 2004,
because of delays Liberty Circle had experienced related to the closing of its
acquisition of the real property in Panama, where Liberty Circle intends to
construct its manufacturing facility. Liberty has now requested that the
closing date be extended to October 24, 2004. Liberty Circle has represented
to the Company that it cleared title and closed the acquisition of the real
property in Panama, however, it has encountered delays associated with the
transfer of funds internationally and complying with the requirements of the
Patriot Act.

The Company agreed to extend the date for closing in exchange for payment of
an additional $500,000 under the terms of the Agreement, bringing the total
payments Amerityre is to received under the Agreement to $7.0 million.
