                    Investors.

         i. The undersigned, or the individual representing the undersigned
entity, if applicable, recognizes that the Company has a limited history of
operations, is a speculative venture, and that the total amount of funds
tendered to purchase the Units is placed at the risk of the business and may be
completely lost. The purchase of the Units as an investment involves substantial
risk.

to bear the economic risk of this investment, (ii) is able to hold the Units for
an indefinite period of time, and (iii) can afford a complete loss of his
investment without any material change in the undersigned's lifestyle, and has

undue financial difficulties or affect the undersigned's ability to provide for
his or its current needs and possible financial contingencies.

         k. The undersigned, or the individual representing the undersigned
entity, if applicable, understands that transfer of the Units, as well as the

(including investment suitability standards). The undersigned, or the individual
representing the undersigned entity, if applicable, realizes that the transferee

suitability standards required of an initial subscriber and, under the
circumstances, the transfer would not violate applicable laws.

         l. All information which the undersigned, or the individual
representing the undersigned entity, if applicable, has provided to the Company
concerning the undersigned's financial position and knowledge of financial and
business matters is correct and complete as of the execution date hereof. If

representing the undersigned entity, if applicable, will immediately provide the
Company with such information.

     4. Indemnification. The undersigned agrees to indemnify and hold harmless
the Company from and against all damages, losses, costs and expenses (including

         a. If the undersigned shall so request in writing within a period of
two years beginning the date of the issuance of the Units purchased hereby, the
Company shall proceed at its own expense to prepare and file with the
Securities and Exchange Commission (the "SEC") one registration statement under
the Securities Act of 1933, as amended, with respect to the shares held by the
purchasers under this offering (the "Selling Shareholders). The registration
statement will include the shares issued as part of the Units and any shares
issued upon exercise of the Warrants. The Company will use its best efforts to

furthermore, at its own expense, use its best efforts to keep said
registrations statement current, in accordance with the rules and regulations of
the SEC for the period ending upon a date six months after the effectiveness

SEC in connection with the registration of additional shares of common stock of
the Company to be sold in a public offering by the Company. Prior to the filing
of such registration statement, the Company shall notify the Selling Shareholder
in writing of the intent of the Company to file the registration statement. If
the Selling Shareholder shall not notify the Company in writing within twenty
(20) days following the mailing of the notice set forth in this subparagraph
that such Selling Shareholder requests registration of the shares, such party
shall be deemed to have waived the right to demand that such shares be
registered pursuant to this Agreement, and the Company shall have no further
obligation to register any of such shares of such Selling Shareholder.

         b. The Company shall bear all expenses incurred by it in registering
the shares of the Selling Shareholders, including without limitation, all
filing, registration and qualification fees of the SEC, printing expenses, fees
and disbursements of legal counsel and all accounting expenses including
expenses of the year-end audits. The Selling Shareholders shall bear the fees
and disbursements of their own legal counsel, underwriting or brokerage
discounts and commissions, expenses of their brokers or underwriters, and fees
of the National Association of Securities Dealers, Inc.

         c. It shall be a condition of the obligations of the Company to take
action in response to any request for registration that such request include or
be accompanied by all of the following: (i) the requesting Selling Shareholder's
confirmation that such Selling Shareholder then has a present intention of
selling or distributing the shares which are the subject of such request; (ii)
information with respect to such Selling Shareholder and the number of shares
proposed to be sold and a description of such shares, or, to the extent that
such information is not then available, such Selling Shareholder's undertaking
to furnish the same; (iii) the indemnity agreement specified in subparagraph (d)
below; (iv) the Selling Shareholder's agreement to refrain, in connection with
such registration, offering and sale, from taking any action violative of the
anti-manipulative rules promulgated under the Securities Exchange Act of 1934,
as amended; and (v) the Selling Shareholder's agreement to cooperate with the
Company generally in connection with such registration, and the undertaking to
execute such further documents relating to formal matters in

                                       -6-




connection with such registration, offering and sale as may be necessary,
appropriate and proper to effectuate the transactions contemplated by such
request.

         d. Any request for registration shall be accompanied by an agreement of
the Selling Shareholder to indemnify the Company, each of its directors, each of
its officers who sign the registration statement, and each person who controls
the Company against any loss, claim, liability, damage or action arising out of
or based on any untrue statement (or alleged untrue statement) of a material
fact contained in the registration statement when the same becomes effective or
in any final prospectus or amendment or supplement thereto, or any omission (or
alleged omission) to state therein a material fact required to be stated therein
or necessary to make the statements therein not misleading, and to reimburse the
indemnified persons for any legal or other expenses reasonably incurred in
investigating or defending any such action or claim, but only to the extent that
the untrue statement (or alleged untrue statement) or omission (or alleged
omission) was made in reliance upon and in conformity with written information
furnished to the Company by or on behalf of the Selling Shareholder for use in
the registration statement, final prospectus, or amendment or supplement
thereto, as the case may be.

     6. Limitations on Transfer of Units. The undersigned acknowledges that he
or it is aware that there are substantial restrictions on the transferability of
the Units, as well as the component parts thereof. Since the Units, as well as
the component parts thereof, will not be, and the undersigned has no right to
require that they be, registered under the Securities Act or any applicable
state securities laws, except as provided herein, the Units, and the component
parts thereof, may not be, and the undersigned agrees that they shall not be,

laws or unless such sale is exempt from such registration under the Securities
Act and any other applicable state securities laws or regulations. The
undersigned further acknowledges that the Company is under no obligation to aid
him or it in obtaining any exemption from the registration requirements. The
undersigned also acknowledges that he or it shall be responsible for compliance
with all conditions on transfer imposed by any securities administrator of any
state and for any expenses incurred by the Company for legal or accounting
services in connection with reviewing such a proposed transfer and/or issuing
opinions in connection therewith.

undersigned's purchase and any resales, pledges, hypothecations or other
transfers of the Units pursuant to the Securities Act:

     UNDER THE SECURITIES ACT OF 1933, AS AMENDED, AND MAY NOT BE SOLD OR
     TRANSFERRED UNLESS A COMPLIANCE WITH THE REGISTRATION PROVISIONS OF SUCH
     ACT HAS BEEN MADE OR UNLESS AVAILABILITY OF AN EXEMPTION FROM SUCH
     REGISTRATION PROVISIONS HAS BEEN ESTABLISHED.

         c. Stop transfer instructions have been or will be placed with respect
to the Units, as well as the component parts thereof, so as to restrict resale,
pledge, hypothecation or other transfer thereof, subject to the further items
hereof, including the provisions of the legend set forth in subparagraph (b)
