1.         The Company and the Employee previously entered into that certain

Employee to the Company, the Company agreed to make a cash payment to Employee
in the event of any Change in Control (as defined in the Original Agreement)
regarding the Company, the amount of which is calculated based upon the Price
Per Share (as defined in the Original Agreement) of the Company’s equity
securities purchased by any buyer at the time of such Change in Control.

2.         The Company and the Employee desire to amend the Original Agreement
in order to (i) extend the term of the Original Agreement to the date one year
from the date of this Amendment and (ii) replace the calculation of the cash
payment based upon the Price Per Share with a one-time lump sum payment of
$250,000 payable in accordance with the terms of the Original Agreement.

agreements contained herein and in the Original Agreement and for other good and
valuable consideration, the receipt and sufficiency of which are hereby
acknowledged, the parties agree as follows:

during the one hundred twenty (120) day period preceding the execution by the
Company of a definitive agreement setting forth a transaction that ultimately
closes and results in a Change In Control occurring during the term of this
Agreement, then upon the consummation of such Change In Control, the Executive
shall receive a retention payment in cash subject to required withholding, in
the aggregate amount of TWO HUNDRED AND FIFTY THOUSAND DOLLARS ($250,000.00 US,

paid to the Executive if (a) the Executive voluntarily terminates his employment
relationship with the Company prior to the Change in Control, or (b) if the

Control because the Executive is convicted of a felony.
