RECITALS

WHEREAS, the Company and Client entered into the Agreement and the Statement of
Work;

WHEREAS, the Company and Client desire to amend the Statement of Work such that
Four Hundred Thousand Dollars ($400,000) of the Initial Payment (as defined in
the Statement of Work) will be applied to the invoices set forth herein subject
to the terms and conditions set forth herein and in the Statement of Work;

WHEREAS, the Company and Client desire to amend the Statement of Work such that

NOW, THEREFORE, in compliance with Section 26 of the Agreement and in
consideration of the mutual promises and covenants set forth herein and in the
Agreement and Statement of Work, the Client and the Company hereby agree as
follows:

The Section entitled "Terms of Payment" in the Statement of Work is hereby
amended to read in its entirety:

"An initial payment ("Initial Payment") of $500,000 will be required prior to
the commencement of Services performed in Phase I. Upon receipt of gross
proceeds on or prior to April 1, 2009 from equity or debt or other financing
obtained by Client from third parties of at least Eight Hundred Thousand Dollars
($800,000) in the aggregate after March 11, 2009, the Client may apply (i) up to
One Hundred Thousand Dollars ($100,000) of the Initial Payment against any
invoice issued by the Company pursuant to the Statement of Work, that is dated
on or after May 1, 2009, (ii) up to an additional One Hundred Thousand Dollars
($100,000) of the Initial Payment against any invoice issued by the Company
pursuant to the Statement of Work, that is dated on or after June 1, 2009, (iii)
up to an additional One Hundred Thousand Dollars ($100,000) of the Initial
Payment against any invoice issued by the Company pursuant to the Statement of
Work, that is dated on or after July 1, 2009, and (iv) up to an additional One
Hundred Thousand Dollars ($100,000) of the Initial Payment against any invoice
issued by the Company pursuant to the Statement of Work, that is dated on or
after August 1, 2009. The remaining amount of Initial Payment shall be applied
to the last invoice for Phase 2 of this project. Any remainder of the Initial
Payment after such last invoice will be returned to the Client with the final
invoice of Phase II unless earlier terminated by Client pursuant to Section 18
of this Agreement. If earlier terminated, the Initial Payment will be applied to
any outstanding Invoices or unbilled Services performed or material purchased by
the Company. Any remainder of the Initial Payment will be returned to the Client
with the final invoice.

Company will bill the Client monthly for labor and weekly for out-of-pocket
expenses, on a time and materials basis. Payment is due 30 days after invoice
date. In addition, during the term of this Agreement, the Company shall bill and
the Client shall reimburse the Company for all reasonable, pre-approved
out-of-pocket expenses which are incurred in connection with the performance of
the Services hereunder. For the avoidance of doubt, Company must obtain the
prior written approval of Client's Project Manager for any expense that exceeds
fifty thousand dollars ($50,000). Client shall have the right to review and
approve the terms and conditions of any such purchase.

The Company will promptly notify the Client Project Manager of any costs,
expenses or fees that will cause the overall cost and fee estimates to exceed by
more than 10% of the estimate set forth in the attached proposals of this
Statement of Work."

The Client and the Company hereby acknowledge and consent to the foregoing
amendments to the Statement of Work as set forth herein.

Except as amended herein, all other terms and provisions of the Agreement and
Statement of Work shall remain in full force and effect.

This Amendment shall be effective upon its execution by the Client and the
Company.

This Amendment may be executed in any number of counterparts, each of which when
so executed shall be deemed to be an original and all of which taken together
shall constitute one and the same agreement and shall become effective when
counterparts have been signed by each party and delivered to the other parties
hereto, it being understood that all parties need not sign the same counterpart.
In the event that any signature is delivered by facsimile or electronic
transmission, such signature shall create a valid binding obligation of the
party executing (or on whose behalf such signature is executed) the same with
the same force and effect as if such facsimile or electronic signature were the
original thereof.

IN WITNESS WHEREOF, the parties have caused this Amendment to be duly executed
and delivered by the proper and duly authorized officers as of the day and year
first written above.
