Seller was not organized for the purpose of acquiring the Shares.

                  3.1.9 Investment Purposes. Seller is acquiring the Shares,
subject to the terms hereof, for investment for its own account and not with a

all information concerning Buyer that it and its financial, tax and legal
advisors required or considered necessary to make a proper evaluation of this
investment. Specifically, Seller has had the opportunity to review Buyer's last
annual report on Form 10-KSB, dated March 31, 2002, and all subsequent filings
by Buyer with the Securities and Exchange Commission. Further, Buyer has advised
Seller that (i) there have been material developments that are not fully
described in such filings, (ii) Buyer's financial statements and other
information contained in such filings do not reflect material changes that have
occurred since the date of the last Buyer financial statement and (iii) Buyer
believes that updated financial and business information would be material to an
investment decision. Notwithstanding the foregoing, Seller has declined to
review, accept or consider additional information in making an investment
decision. In making the decision to acquire the Shares, Seller and its advisers
have relied solely upon their own independent investigations, and fully
understand that there are no guarantees, assurances or promises in connection
with any investment hereunder and understand that the particular tax
consequences arising from this investment in Buyer will depend upon its
individual circumstances. Seller further understands that no opinion is being
given as to any securities or tax matters involving the offering.

<PAGE>

                  3.1.11 Exempt Transaction. Seller understands that the Shares
have not been registered under the Securities Act and must be held indefinitely
unless a subsequent disposition thereof is registered under the Securities Act
or is exempt from such registration.

                  3.1.12 Legend. Seller also understands and agrees that stop
transfer instructions relating to the Shares will be placed in Buyer's stock
transfer ledger, and that the certificates evidencing the Shares will bear
legends in substantially the following form:

                  The securities represented by this certificate have not been
                  registered under the Securities Act of 1933 (the "Act") and
                  are "restricted securities" as that term is defined in Rule
                  144 under the Act. The securities may not be offered for sale,
                  sold or otherwise transferred except pursuant to an effective
                  registration statement under the Act or pursuant to an
                  exemption from registration under the Act, the availability of
                  which is to be established to the satisfaction of the Company.

representations and warranties of the Seller set forth in Section 3.1 hereof

                    REPRESENTATIONS AND WARRANTIES OF SELLER

         3.1 Representations and Warranties. Seller hereby represents and
warrants the following to Buyer. Buyer and Seller have entered into this
Agreement on the condition that Seller make the following representations and
warranties, which representations and warranties were and are a material
inducement to Buyer entering into this Agreement, and Buyer would not have
entered into this Agreement except in reliance upon the representations and
warranties of Seller made herein.

                  3.1.1 Consents. All required approvals or consents have been
obtained in connection with the execution of this Agreement by Seller and with
the performance by Seller of Seller's obligations hereunder.

<PAGE>

                  3.1.2 Contracts. Neither this Agreement nor the transactions
contemplated hereby violates or shall violate any contract, document,
understanding, agreement or instrument to which Seller is a party or by which
Seller may be bound, or any contract, document, understanding, agreement or
instrument affecting the Assets.

                  3.1.3 Lawsuits. Seller has received no written notice of any
pending or threatened lawsuits or asserted or unasserted claims, condemnation or
eminent domain proceedings, or proceedings in lieu thereof, relating to the
Assets.

                  3.1.4 Notice of Violation. Seller has not received
notification of any violation of any laws, rules or regulations with respect to,
or which would affect the use of the Assets.

                  3.1.5 Contracts. There are no contracts relating to the Assets
to which Seller is a party, or which Seller has assumed, has agreed to be bound
by or has agreed to pay on, that will obligate Buyer (except for the Assumed

                  3.1.6 Authority. Seller has been duly authorized to enter into
this Agreement and to sell the Assets pursuant to the terms and conditions
hereof, and the parties and persons executing this Agreement on behalf of Seller

contracts, collateral security arrangements, or other title or interest
retention arrangements.

                  3.1.8 Accredited Investor Status. Seller and Morris are
"accredited investors" for purposes of Regulation D under the Securities Act of
1933, as amended (the "Securities Act") and both Seller and Morris have
sufficient knowledge and experience in evaluating and investing in companies
similar to Buyer in terms of Buyer's stage of development so as to be able to
evaluate the risks and merits of his or its investment in Buyer and is able
financially to bear the risks thereof. Seller was not organized for the purpose
of acquiring the Shares.

                  3.1.9 Investment Purposes. Seller and Morris are acquiring the
Shares, subject to the terms hereof, for investment for their own account and
not with a view to, or for resale in connection with, any distribution thereof,
and neither Seller nor Morris have any present intention of selling or granting
any participation in, or otherwise distributing the same. By executing this

sell, transfer or grant participations to such person or to any third person,
with respect to any of the Shares.

                  3.1.10 Access to Information. Seller and Morris have had
access to any and all information concerning Buyer that they and their
financial, tax and legal advisors required or considered necessary to make a
proper evaluation of this investment. Specifically, Seller and Morris have had
the opportunity to review Buyer's last annual report on Form 10-KSB, dated March
31, 2002, and all subsequent filings by Buyer with the Securities and Exchange
Commission. Further, Buyer has advised Seller and Morris that (i) there have

<PAGE>

been material developments that are not fully described in such filings, (ii)
Buyer's financial statements and other information contained in such filings do
not reflect material changes that have occurred since the date of the last Buyer
financial statement and (iii) Buyer believes that updated financial and business
information would be material to an investment decision. Notwithstanding the
foregoing, Seller and Morris have declined to review, accept or consider
additional information in making an investment decision. In making the decision
to acquire the Shares, Seller and Morris and their advisers have relied solely
upon their own independent investigations, and fully understand that there are
no guarantees, assurances or promises in connection with any investment
hereunder and understand that the particular tax consequences arising from this
investment in Buyer will depend upon their individual circumstances. Seller and
Morris further understand that no opinion is being given as to any securities or
tax matters involving the offering.

                  3.1.11 Exempt Transaction. Seller and Morris understand that
the Shares have not been registered under the Securities Act and must be held
indefinitely unless a subsequent disposition thereof is registered under the
Securities Act or is exempt from such registration.

                  3.1.12 Legend. Seller and Morris also understand and agree
that stop transfer instructions relating to the Shares will be placed in Buyer's
stock transfer ledger, and that the certificates evidencing the Shares will bear
legends in substantially the following form:

                  The securities represented by this certificate have not been
                  registered under the Securities Act of 1933 (the "Act") and
                  are "restricted securities" as that term is defined in Rule
                  144 under the Act. The securities may not be offered for sale,
                  sold or otherwise transferred except pursuant to an effective
                  registration statement under the Act or pursuant to an
                  exemption from registration under the Act, the availability of
                  which is to be established to the satisfaction of the Company.
