As previously disclosed in a Form 8-K filed on August 15, 2008, the Company and Elitech proposed to combine the two companies pursuant to the terms of the Share Exchange Agreement (the “Business Combination”). If the Business Combination is not consummated by March 31, 2009, each party has the right to terminate the Share Exchange Agreement. The Company, Elitech and Sellers acknowledge that, despite their best efforts and due to events beyond their control, it has become unlikely that the Business Combination will be completed by March 31, 2009. As such, the parties believe that it is in the best interest of all participants to enter into the Consent and Waiver to remove certain restrictions on the Company with respect to its solicitation activities, and to waive certain obligations of the parties under the Share Exchange Agreement.

The foregoing is a summary description of certain terms of the Consent and Waiver. It is qualified in its entirety by the text of a copy of such document attached as exhibit 10.1 to this Current Report on Form 8-K and incorporated herein by reference.
