CIVITAS REPORTS CONTINUED STRONG GROWTH AND IMPROVING PROFITS

FRANKLIN, Tenn. (02-01-2007) — Civitas BankGroup (NASDAQ:CVBG) today reported net income of $6.7 million and strong loan growth at its subsidiary, Cumberland Bank for the year ended December 31, 2006. The $6.7 million twelve months net income from continuing operations represents a $2.8 million or 71.2% increase from the comparable period in 2005. On a per share basis, 2006 net income from continuing operations totaled $0.42 per share, compared to $0.24 per share in 2005.

Net income for the twelve months ended December 31, 2006, included a non-recurring $2.1 million (after tax) gain related to the company’s sale of its 50% interest in the Murray (Kentucky) Bank. Earnings for the twelve months ended Dec. 31, 2006, excluding this gain, were $4.6 million, compared to earnings from continuing operations of $3.9 million for the same period of 2005.

Net income for the fourth quarter 2006 was $1.2 million ($0.08 per share), an increase of 18.3% over the fourth quarter 2005. Fourth quarter and annual earnings were both impacted by merger related expenses of approximately $400,000 associated with Civitas’ planned merger with Greene County Bancshares, Inc. On January 25, 2007, Civitas BankGroup announced that it had entered into an agreement and planned merger with Greene County Bancshares, Inc.
