WHEREAS, the Company proposes to raise gross proceeds of up to $2,000,000 by
selling Secured Convertible Debentures to Cornell Capital Partners, LP
(“Cornell”) pursuant to a Securities Purchase Agreement of even date herewith;
and

WHEREAS, Cornell requires, as a condition to such transaction, that Cheshire
pledge 6,000,000 shares of Company common stock, par value $.0025 per share, to
Cornell, as partial security for the Company’s obligations under the Secured
Convertible Debentures; and

WHEREAS, the Company is willing to enter into this Agreement in order to induce
such pledge; and

WHEREAS, the parties contemplate that such pledge will be created via that
certain Insider Pledge and Escrow Agreement, dated of even date herewith, by and
among the Company, Cheshire, Cornell and David Gonzalez, Esq. (the “Insider
Pledge and Escrow Agreement”); and

WHEREAS, pursuant to this Agreement and the Insider Pledge and Escrow Agreement,
Cheshire shall pledge 6,000,000 shares of Company common stock to Cornell as
partial security for the Company obligations under one or more Secured
Convertible Debentures to be issued today and/or hereafter by the Company to
Cornell, with an aggregate principal amount of up to $2,000,000, in
consideration of the Company’s agreement herein to issue a formula-determined
number of 5-year Company common stock warrants to Cheshire and further subject
to the terms set forth herein.

NOW, THEREFORE, in consideration of the foregoing and the mutual covenants and
promises contained herein, and for other good and valuable consideration, the
receipt and sufficiency of which are hereby acknowledged, the parties agree as
follows:

1. Cheshire shall execute, deliver and perform the Insider Pledge and Escrow
Agreement, including delivering to the escrow agent thereunder a share
certificate representing 6,000,000 shares of Company common stock and a stock
power, duly executed in blank by Cheshire and with Medallion guaranty stamp
affixed.

2. The Company and Cheshire shall thereupon execute and deliver the Warrant
Agreement, in the form attached hereto as Exhibit A. The initial exercise price
under the Warrant Agreement shall be 100% of the closing sale price of the
Company common stock on the Nasdaq SmallCap Market on the initial closing date
of the Securities Purchase Agreement

3. It is understood that pursuant to Section 4(b) of the Insider Pledge and
Escrow Agreement, Cornell will release the pledged Cheshire shares when and if
the Company obtains stockholder approval for issuance of all shares called for
by the Company’s various agreements with Cornell, and the Company has entered
into a Pledge and Escrow Agreement with Cornell, of like tenor as the Pledge and
Escrow Agreement dated today between the Company and Cornell, but this time
pledging under such future Pledge and Escrow Agreement an additional 9,326,000
shares of Company common stock, and no “Event of Default” (within the meaning of
the Insider Pledge and Escrow Agreement) shall have been deemed to have
occurred. The Company agrees to use its best efforts to:

(a) expeditiously seek and obtain such stockholder approval;

  (b)   expeditiously thereafter enter into such future Pledge and Escrow
Agreement and pledge such additional 9,326,000 shares to Cornell; and

(c) avoid the occurrence of an Event of Default.
