Section 3.1. Organization. If not a natural person, the Investor is duly
organized, validly existing and in good standing under the laws of its
jurisdiction of organization.

Section 3.2. Intent. The Investor is entering into this Agreement for its own
account and not with a view to or for sale in connection with any distribution
of the Common Stock. The Investor has no present arrangement (whether or not
legally binding) at any time to sell the Common Stock, Warrants or Warrant
Shares to or through any Person or entity; provided, however, that by making the
representations herein, the Investor does not agree to hold such securities for
any minimum or other specific term (other than as specified in Section 4.3

at any time in accordance with federal and state securities laws applicable to
such disposition and such Section 4.3.

(as described in Rule 506(b)(2)(ii) of Regulation D) and an accredited investor
(as defined in Rule 501 of Regulation D), and the Investor has such experience
in business and financial matters that it has the capacity to protect its own
interests in connection with this transaction and is capable of evaluating the
merits and risks of an investment in the Common Stock, Warrants and Warrant
Shares. The Investor acknowledges that an investment in the Common Stock,
Warrants and Warrant Shares is speculative and involves a high degree of risk.

Section 3.4. Authority. This Agreement and each agreement attached as an Exhibit
hereto which is required to be executed by the Investor has been duly authorized
and validly executed and delivered by the Investor and is a valid and binding
agreement of the Investor enforceable against it in accordance with its terms,
subject to applicable bankruptcy, insolvency, or similar laws relating to, or
affecting generally the enforcement of, creditors' rights and remedies or by
other equitable principles of general application.

Section 3.5. Not an Affiliate. The Investor is not an officer, director or
"affiliate" (as that term is defined in Rule 405 of the Securities Act) of the
Company.

Section 3.6. Disclosure; Access to Information. The Investor has received all
documents, records, books and other publicly available information pertaining to
Investor's investment in the Company that have been requested by the Investor.
The Company is subject to the periodic reporting requirements of the Exchange
Act, and the Investor has reviewed copies of all SEC Documents deemed relevant
by the Investor.

Section 3.7. Manner of Sale. At no time was the Investor presented with or
solicited by or through any leaflet, public promotional meeting, television
advertisement or any other form of general solicitation or advertising.

         Each Investor, severally and not jointly, covenants with the Company
that:

Section 4.1. Compliance with Law. The Investor's trading activities with respect
to shares of the Company's Common Stock will be in compliance with all
applicable state and federal securities laws, rules and regulations and rules
and regulations of the Principal Market on which the Company's Common Stock is
listed.

Section 4.2. Limitation on Short Sales. The Investor agrees that it will make no
short sales (as defined in any applicable SEC or NASD rules) of the Company's
Common Stock while the Investor holds any of the Common Stock issued hereunder.

Section 4.3. Restrictions on Transfer of Common Stock. Notwithstanding the
filing and effectiveness of the Registration Statement, the Investor agrees to
Transfer the Common Stock (not including the Warrant Shares) only as follows:

         (a) The Investor may Transfer up to twenty-five percent (25%) of the
aggregate number of shares of Common Stock upon the earlier of (i) 180 days
after the Closing Date and (ii) the close of the fifth consecutive Trading Day
on which the closing sales price of the Common Stock on the Principal Market is
at least $2.00 per share.

         (b) The Investor may Transfer the remaining seventy-five percent (75%)
of the aggregate number of shares of Common Stock upon the earlier of (i) one

Registration Statement and (ii) 180 days after the Closing Date.

                            Covenants of the Company

Section 5.1. Registration Rights. The Company shall cause the Registration
Rights Agreement to remain in full force and effect and the Company shall comply
in all material respects with the terms thereof.

Section 5.2. Reservation of Common Stock. As of the date hereof, the Company has
reserved and the Company shall continue to reserve and keep available at all
times, free of preemptive rights, shares of Common Stock for the purpose of
enabling the Company to issue the Warrant Shares pursuant to the exercise of the
Warrants. The number of shares so reserved from time to time, as theretofore
increased or reduced as hereinafter provided, may be reduced by the number of
shares actually delivered pursuant to any exercise of the Warrants and the
number of shares so reserved shall be increased or decreased to reflect
potential increases or decreases in the Common Stock that the Company may
thereafter be obligated to issue by reason of adjustments to the Warrants.
