equity, including without limitation, concepts of materiality, reasonableness,
good faith and fair dealing and the possible unavailability of specific
performance and injunctive relief, regardless of whether considered in a
proceeding in equity or at law.

         3.2      PURCHASE ENTIRELY FOR OWN ACCOUNT. This Agreement is made with
Investor in reliance upon Investor's representation to the Company, which, by
Investor's execution of this Agreement, Investor hereby confirms that the Shares
to be purchased by Investor hereunder will be acquired for investment purposes
only and for Investor's own account, not as a nominee or agent, and not with a
view to the resale or distribution of any part thereof, and that Investor has no
present intention of selling, granting any participation in, or otherwise
distributing the same. By executing this Agreement, Investor further represents
that Investor does not have any contract, undertaking, agreement or arrangement
with any person to sell, transfer or grant participations to such person or to
any third person, with respect to any of the Shares.

         3.3      DISCLOSURE OF INFORMATION. Investor has received all the
information Investor considers necessary or appropriate for deciding whether to
purchase the Shares to be purchased hereunder. Investor acknowledges that: (i)
Investor has pursued its own independent investigation of the Company and of any
information that Investor considers material to its investment decision; (ii)
Investor has read the Form 10-KSB filed by the Company for its fiscal year
ending September 30, 2000, the Forms 10-QSB filed by the Company for the
quarters ending December 31, 2000, March 31, 2001, and September 30, 2001, and
the Form 10-QSB/A filed by the Company for the quarter ending December 31, 2000;
and (iii) Investor is relying solely upon such independent investigation, the
information contained in the aforementioned Form 10-KSB, two Forms 10-QSB and
Form 10-QSB/A and the representations and warranties contained in Section 2 of
this Agreement. Investor further represents that Investor has had an opportunity
to ask questions and receive answers and information from the Company regarding

and financial condition of the Company.

         3.4      INVESTMENT EXPERIENCE; NO ORAL REPRESENTATIONS. Investor is an
experienced investor in securities and acknowledges that Investor is able to
fend for him/her/itself, can bear the economic risk of Investor's investment,
and has such knowledge and experience in financial or business matters that
Investor is capable of evaluating the merits and risks of the investment in the
Shares to be purchased hereunder. In evaluating the merits and risks of an
investment in the Shares, Investor has relied, in part, upon the advice of
Investor's legal counsel, tax advisors, and/or other investment advisors. At no
time was any oral representation made to Investor relating to the purchase of
the Shares or was Investor presented with or solicited by any form of general
advertising relating to the purchase hereunder. Investor has not relied on any
verbal statements or representations made to Investor in determining whether to
purchase the Shares hereunder. Investor is prepared to bear the risk of losing
part or all of Investor's investment in the Shares, and Investor acknowledges
the inability to sell or transfer the Shares for an indefinite period of time or
at a price which would enable Investor to recoup the investment in the Shares.
INVESTOR UNDERSTANDS THAT NO PUBLIC MARKET NOW EXISTS FOR THE SHARES AND THAT
THERE IS NO ANTICIPATED FUTURE PUBLIC MARKET FOR THE SHARES.

                                      -3-
<PAGE>


         3.5      RESTRICTED SECURITIES. Investor understands that the Shares to
be purchased hereunder are characterized as "restricted securities" under the
federal and state securities laws inasmuch as they will be acquired from the
Company in a transaction not involving a public offering and that under such
laws and applicable regulations such securities may not be resold without
registration under the Act and applicable state securities laws or pursuant to
an exemption therefrom. In this connection, Investor represents that Investor is
familiar with Rule 144 promulgated under the Act ("RULE 144") and understands
the resale limitations imposed thereby. Investor is aware that an investment in
non-publicly traded securities such as the Shares is nonmarketable,
nontransferable and will require Investor's capital to be invested for an
indefinite period of time, possibly without return. Investor has no need for
liquidity in this investment, has the ability to bear the economic risk of this
investment, and can afford a complete loss of the entire purchase price paid for
the Shares.

         3.6      NO DISPOSITION DURING FIRST YEAR. Investor understands that
the Shares to be purchased hereunder may not be sold, transferred or disposed of
for one year after the Closing Date. Investor understands that, pursuant to Rule
144, affiliates (as "affiliate" is defined in Rule 144) and non-affiliates may
resell the Shares only after holding such securities for at least one year,
subject to certain sales volume limitations and other requirements contained in
Rule 144. Investor further understands that the requirements of Rule 144 may
change prior to Investor selling any Shares and that the Company has provided no
assurance that the sale of any such securities will be eligible for resale
pursuant to Rule 144 under any particular circumstances.

         3.7      FURTHER LIMITATIONS ON DISPOSITION. Without in any way
limiting the representations set forth above is this Section 3, Investor further
agrees not to make any disposition of all or any portion of the Shares purchased
hereunder unless:

                  (i)      There is then in effect a registration statement
under the Act and applicable state securities laws covering such proposed
disposition and such disposition is made in accordance with such registration
statement;

                  (ii)     Investor shall have (a) notified the Company of the
proposed disposition and shall have furnished the Company with a detailed
statement of the circumstances surrounding the proposed disposition, and (b)
furnished the Company with evidence including an opinion of counsel, reasonably
satisfactory to the Company, that such disposition will not require registration
of such Shares or shares under the Act; or

                  (iii)    The disposition is pursuant to Rule 144.

         3.8      LEGENDS. It is understood that the Shares purchased hereunder
have not been registered under the Act and that Common Stock certificates
evidencing said Shares may bear one or all of the following legends:

                  (i)      "The securities evidenced hereby have not been
                           registered under the Securities Act of 1933, as
                           amended, or any state securities laws. They may not
                           be sold, offered for sale, pledged or hypothecated in
                           the absence of a registration statement in effect
                           with respect to the securities under such Act and any
                           applicable state securities laws or an opinion of
                           counsel

                                      -4-

                           satisfactory to the Company that such registration is
                           not required or unless sold pursuant to Rule 144 of
                           such Act."

                  (ii)     Any legend required by any applicable state
                           securities laws.

         3.9      NO PREEMPTIVE RIGHTS OR ANTI-DILUTION PROTECTION. Investor
understands that Investor will not be entitled to any anti-dilution protection.
Investor understands that the Company may periodically issue additional Common
Stock or Preferred Stock or other equity or debt securities of the Company, and

by the Company.
