Merger with Premier Alliance Group, Inc.

Effective March 5, 2012, the Registrant consummated the merger whereby Registrant merged with GHH Acquisition Company, Inc. (“Merger Sub”), a wholly-owned subsidiary of Premier Alliance Group, Inc., a Delaware corporation (“Premier”) pursuant to the Agreement and Plan of Merger (“Merger Agreement”) with Premier and Merger Sub. Pursuant to the Merger Agreement, the Merger Sub merged with and into the Registrant with the Registrant remaining the surviving corporation of the merger (the “Merger”) and a wholly -owned subsidiary of Premier.

Pursuant to the Merger Agreement, all of the issued and outstanding shares of capital stock of the Registrant, excluding options and warrants to purchase Registrant capital stock (collectively, the “GHH Stock”) were converted into the right to receive a number of newly issued shares of Premier’s common stock representing forty (40%) percent of Premier’s issued and outstanding capital stock (the “Merger”) immediately following the Merger on a fully diluted basis including the merger shares, subject to adjustment resulting from the conversion of the GHH Convertible Note (defined in the Agreement), and excluding options and warrants to purchase Premier capital stock (the “Merger Shares”). The final exchange ratio of shares of GHH Stock for shares of common stock of Premier is .13954156 shares of Premier common stock for each share of GHH Stock exchanged in the Merger. Certain shares which otherwise would be delivered to the Registrant’s principal shareholders, officers and directors, totaling 1,334,678 shares, representing approximately 18.8% of the shares issued to the Registrant’s shareholders, have been delivered to an escrow agent, to be released pending the achievement of certain revenue goals and to secure certain indemnification obligations.
