any State Securities Laws.  The Company will cause the Secretary of the

Shares in the registration of the Company  securities that the Company shall
file with the United States Securities and Exchange Commission on or before
July 1, 2000.

     (c)     Expenses.  All fees, disbursements and expenses incurred by the

5)     Representations and Warranties.  The Subscriber hereby represents and
warrants to and covenants with the Company, as well as each officer, director
and agent of the Company as follows:

     (a)     General

         (i)     The Subscriber has all requisite authority to enter into this
Subscription Agreement and to perform all the obligations required to be
performed by the Subscriber hereunder.

the business and may be completely lost.  The purchase of the Exchange Shares
of the Company as an investment involves extreme risk.

         (iv)     The Subscriber realizes that the Exchange Shares cannot
readily be sold as the shares of Exchange Shares are restricted securities,
that it may not be possible to sell or dispose of the Exchange Shares and
therefore the Exchange Shares must not be purchased unless the Subscriber has
liquid assets sufficient to assure that such purchase will cause no undue
financial difficulties and the Subscriber can provide for current needs and
personal contingencies.

         (v)     The Subscriber confirms and represents that it is able (a) to
bear the economic risk of its investment, (b) to hold the securities for an
indefinite period of time, and (c) to afford a complete loss of its
investment.  The Subscriber also represents that it has adequate means of
providing for its current needs and personal contingencies, and has no need
for liquidity in this particular investment.

         (vi)     The Subscriber has not become aware of the offering of
Exchange Shares of the Company by any form of general solicitation or
advertising, including, but not limited to advertisements, articles, notices
or other communications published in any newspaper, magazine or other similar
media or broadcast over television or radio or any seminar or meeting where
those individuals that have attended have been invited by any such or similar
means of general solicitation or advertising.

     (b)     Information Concerning the Company.

         (i)     The Subscriber acknowledges that it has received all current
information about the Company including the Company's  (A) Form 10-KSB for the
fiscal year ended June 30, 1999, as amended and (B) Forms 10-QSB for the
quarters ended September and December 31, 1999.

         (ii)     The Subscriber or its representative is familiar with the
business and financial condition, properties, operations and prospects of the
Company, and, at a reasonable time prior to the execution of this Subscription
Agreement, that it and its representative have been afforded the opportunity
to ask questions of and receive satisfactory answers from the Company's
officers and directors, or other persons acting on the Company's behalf,
concerning the business and financial condition, properties, operations and
prospects of the Company and concerning the terms and conditions of the
offering of the Exchange Shares and has asked such questions as it or its
representative desires to ask and all such questions have been answered to the
full satisfaction of the Subscriber.

         (iii)     The Subscriber understands that, unless the Subscriber
notifies the Company in writing to the contrary before the Closing, all the
representations and warranties contained in this Subscription Agreement will
be deemed to have been reaffirmed and confirmed as of the Closing, taking into
account all information received by the Subscriber.

         (iv)     The Subscriber understands that the purchase of the Exchange
Shares involves various risks, including, but not limited to, those outlined
in this Subscription Agreement.

         (v)     The Subscriber acknowledges that no representations or

has requested have been made available to the Subscriber.

         (vii)     The Subscriber or its representative has been provided
access to all information requested in evaluating its purchase of the Exchange
Shares.

          (viii)     The Subscriber agrees to furnish any additional
information requested to assure compliance with applicable Federal and State
Securities Laws in connection with the purchase and sale of the Exchange
Shares.

     (c)     Restrictions on Transfer or Sale of the Exchange Shares

         (i)     The Subscriber is acquiring the Exchange Shares subscribed
solely for the Subscriber's own beneficial account, for investment purposes,
and not with view to, or for resale in connection with, any distribution of
the Exchange Shares.  The Subscriber understands that the offer and the sale
of the Exchange Shares has not been registered under the Act or any State
Securities Laws by reason of specific exemptions under the provisions thereof
which depend in part upon the investment intent of the Subscriber and of the
other representations made by the Subscriber in this Subscription Agreement.
The Subscriber understands that the Company is relying upon the
representations, covenants and agreements contained in this Subscription
Agreement (and any supplemental information) for the purposes of determining
whether this transaction meets the requirements for such exemptions.

         (ii)     The Subscriber understands that the Exchange Shares are
"restricted securities" under applicable federal securities laws and that the
Act and the rules of the Securities and Exchange Commission (the "Commission")
provide in substance that the Subscriber may dispose of the Exchange Shares
only pursuant to an effective registration statement under the Act or an
exemption therefrom. The certificates evidencing the shares of Common stock
offered hereby will bear a legend that clearly sets forth this restriction.
While the Company has granted certain piggy-back registration rights to the
Subscriber, no assurance can be given as to when or if any registration
statement will become effective. The Subscriber understands that the
Subscriber may not at any time demand the purchase by the Company of the
Subscriber's Exchange Shares.

         (iii)       The Subscriber agrees:  (A) that the Subscriber will not
sell, assign, pledge, give, transfer or otherwise dispose of the Exchange
Shares or any interest therein, or make any offer or attempt to do any of the
foregoing, except pursuant to a registration of the Exchange Shares under the
Act and all applicable State Securities Laws or in a transaction which is
exempt from the registration provisions of the Act and all applicable State
Securities Laws;  (B) that the Company and any transfer agent for the Exchange
Shares shall not be required to give effect to any purported transfer of any
of the Exchange Shares except upon compliance with the foregoing restrictions;
and (C) that a restrictive legend will be placed on the certificates
representing the Exchange Shares.

         (iv)      The Subscriber has not offered or sold any portion of the
subscribed for Exchange Shares and has no present intention of dividing such
Exchange Shares with others or of reselling or otherwise disposing of any
portion of such Exchange Shares either currently or after the passage of a
fixed or determinable period of time or upon the occurrence or nonoccurrence
of any predetermined event or circumstance.

6)     Survival and Indemnification.  All representations, warranties and
covenants contained in this Agreement and the indemnification contained in
this Paragraph 6 shall survive (i) the acceptance of the Subscription
Agreement by the Company  and (ii) the death or disability of the Subscriber.
The Subscriber acknowledges the meaning and legal consequences of the
representations, warranties and covenants in Paragraph 5 hereof and that the
Company has relied upon such representations, warranties and covenants in
determining the Subscriber's qualification and suitability to purchase the
Exchange Shares.  The Subscriber hereby agrees to indemnify, defend and hold
harmless the Company, and its officers, directors, employees, agents and
controlling persons, from and against any and all losses, claims, damages,
liabilities, expenses (including attorneys' fees and disbursements), judgment
or amounts paid in settlement of actions arising out of or resulting from the
untruth of any representation herein or the breach of any warranty or covenant
herein.  Notwithstanding the foregoing, however, no representation, warranty,
covenant or acknowledgment made herein by the Subscriber shall in any manner
be deemed to constitute a waiver of any rights granted to it under the
Securities or State Securities laws.
