Gentlemen:

legally bound, hereby irrevocably agrees, on the terms and conditions set forth
herein, to purchase from Rotary Power International, Inc., a Delaware
corporation (the "Company"), that number of shares (the "Shares") of the
Company's Common Stock, par value $0.01 per share (the `Common Stock"), set
forth on the signature page hereof. The terms and provisions of the Common Stock
are more fully described in the Company's Term Sheet (the "Term Sheet"). The
Company intends to use the proceeds from the sale of the Shares to the Purchaser
for its general business and working capital purposes.

2.       CLOSING AND PAYMENT. On the Date of Closing (as defined below), the
Purchaser shall deliver, by check, electronic transfer or otherwise, as payment
of the purchase price for the Shares an amount equal to $0.18 US for every Share
which the Purchaser has agreed to purchase (as set forth on the signature page
hereto) and the Company shall deliver the Shares to the Purchaser simultaneously
therewith. The Shares which are delivered to the Purchaser on the Date of
Closing (i) have not been registered under the Securities Act of 1933, as
amended (the "Securities Act"), or the securities laws of any state and said
Shares may not be sold, transferred, pledged or hypothecated to any person or
entity unless they have been so registered or the Company shall have received an
opinion of counsel satisfactory to the Company to the effect that registration
thereof for purposes of transfer is not required under the Securities Act, (ii)
shall contain a legend stating that the Shares have not been registered under
the Securities Act or the securities laws of any state and the restrictions on
transferability set forth in Section 2 (i) hereof, and (iii) shall be registered
in the name of the Purchaser. The "Date of Closing" for all purposes of this
Subscription Agreement shall mean February 15, 2000, or any other date mutually
agreed upon in writing by the Purchaser and the Company. Notwithstanding
anything contained herein to the contrary, if the Company cannot deliver the
Shares to the Purchaser on the Date of Closing in conformity with the provisions
of this paragraph, the Purchaser shall have no obligation to purchase the Shares
or deliver to the Company the amount required by the first sentence of this
paragraph.

was invited by, or any solicitation of a subscription by, a person not

generally;

(e) The Purchaser has taken no action which would give rise to any claim by any
person for brokerage commissions for which RPI would be liable, finders' fees or
the like relating to this Subscription Agreement or the transactions
contemplated hereby;

(f) The Purchaser has such knowledge and experience in financial, tax, and
business matters, in general, and investments in securities, in particular, so
as to enable him to utilize the information made available to him in connection
with the offering of the Shares to evaluate the merits and risks of an
investment in the Shares and to make an informed investment decision with
respect thereto;

(g) The Purchaser is not relying on the Company, or any of its employees or

investment in the Shares, and the Purchaser has relied on the advice of, or has
