This letter is being delivered to you in accordance

one share of Common Stock (each, a “Warrant”).


 


In order to induce the
Company and the Underwriter to enter into the Underwriting Agreement and to

(ii) the questionnaires furnished by the undersigned to the Company and
the Underwriter and attached hereto as Exhibit B are true and accurate in
all respects.  The undersigned further represents and warrants that:


 


(a)           The
undersigned is not subject to or a respondent in any legal action for any
injunction, cease-and-desist order or order or stipulation to desist or refrain
from any act or practices relating to the offering of securities in any
jurisdiction;


 


(b)           The

commodities license or registration denied, suspended or revoked.


 


The undersigned
understands that the Underwriter may conduct a background check with respect to
the undersigned, and hereby authorizes any employer, financial institution or
consumer credit reporting agency to release to the Underwriter and its legal
representatives or agents (including any investigative search firm retained by
the Underwriter) any information they may have about the undersigned’s
background and finances (“Information”).  Neither the Underwriter nor its
agents shall be violating the undersigned’s right of privacy in any manner in
requesting and obtaining the Information or in otherwise performing a
background check, and the undersigned hereby releases them from liability for
any damage whatsoever in that connection.


 


The undersigned
acknowledges and understands that the Underwriter and the Company will rely
upon the agreements, representations and warranties set forth herein in
proceeding with the IPO.
