The Palmetto Bank Receives $100 Million in Capital Commitments

CapGen Financial Partners, Patriot Financial Partners, and Others Commit to $100 Million Investment

Greenville, S.C. – Palmetto Bancshares, Inc., a bank holding company whose principal banking subsidiary is The Palmetto Bank, announced today that it has entered into formal stock purchase agreements with institutional investors to invest $100 million in the Company’s common stock in a private placement. The executed commitments include $55 million from CapGen Financial Partners as previously announced, $23.3 million from Patriot Financial Partners, $10.4 million from Sandler O’Neill Asset Management, and the remaining $11.3 million from other institutional investors. As previously announced, the investors intend to purchase shares of Company common stock at $2.60 per share.

“Two weeks ago we announced the initial $55 million commitment from CapGen. Announcement today of the remaining $45 million in commitments, including from other well respected funds like Patriot Financial Partners and Sandler O’Neill Asset Management, is further confirmation of the progress being made to strengthen the Company,” said Samuel L. Erwin, Chief Executive Officer. Erwin continued, “We have been hard at work executing the Strategic Project Plan we adopted in June 2009 to address the loan portfolio credit quality issues which resulted from the extended recession of the past two years. We expect that raising capital, combined with an improving economy, will accelerate our road to recovery and return to profitability in the post-recession environment.”

The consummation of the private placement is subject to a number of conditions, including approval by the Company’s shareholders of a proposal to increase the number of authorized shares of common stock and the investors receiving the necessary bank regulatory approvals and determinations. As a result of the private placement, the Company’s annual meeting of shareholders scheduled for June 22, 2010 will be rescheduled to a later date and the proxy statement for the meeting will be mailed to shareholders prior to the meeting. Each of the Company’s directors and executive officers has agreed to vote his or her shares in favor of the matters to be voted upon in connection with the private placement. The Company also plans to include in the proxy statement the slate of directors proposed for election. Under the stock purchase agreement with the investors, the Company also is permitted to conduct a $10 million follow on offering after the closing of the private placement that would allow current shareholders to purchase common stock of the Company.

“Completing the capital raise is a very important step for us,” said L. Leon Patterson, Chairman of the Board. “We appreciate the loyal support of our shareholders over our 103-year history, and we are excited about the future. We are committed to moving forward in our second century of serving the Upstate of South Carolina with innovative ways of banking while continuing to provide outstanding customer service.”

The Company expects to use the net proceeds from the private placement primarily to contribute capital to The Palmetto Bank. The capital contribution to the Bank will result in the Bank’s capital adequacy ratios exceeding the minimum capital levels required to be categorized as “well capitalized”.

Howe Barnes Hoefer & Arnett, Inc. served as the sole placement agent for the transaction.
