1.	Registration Statement No. 333-196654, which was filed with the SEC on June 11, 2014.
2.	Registration Statement No. 333-172506, which was filed with the SEC on February 28, 2011.

On April 22, 2015, the Company entered into an Agreement and Plan of Merger (the “Merger Agreement”) with United Community Banks, Inc., a Georgia corporation and the holding company for United Community Bank (“United”). On September 1, 2015, pursuant to the Merger Agreement, the Company was merged with and into United, with United being the surviving entity (the “Merger”).

In connection with the Merger, the Company has terminated all offerings of the Company’s securities pursuant to the Registration Statements. In accordance with an undertaking made by the Company in the Registration Statements to remove from registration, by means of a post-effective amendment, any securities that had been registered for issuance but remain unsold at the termination of the offerings, the Company removes from registration any and all shares of the Company common stock that were registered for issuance and that have not been sold by the holders of such securities through the Registration Statements as of the effective time of the Merger. The Company is filing the Post-Effective Amendment to reflect the deregistration of such securities.

The foregoing description of the Merger, the Merger Agreement and the transactions contemplated thereby does not purport to be complete and is subject to, and qualified in its entirety by, the Merger Agreement, which is attached as Exhibit 2.1 to the Company’s Form 8-K, filed with the SEC on April 22, 2015.
