[NYSE: FNB] and Slippery Rock Financial Corporation ("Slippery Rock") [OTC BB: SRCK] today jointly announced the signing of a definitive merger agreement. Under the agreement, F.N.B. will acquire Slippery Rock in a stock and cash transaction valued at $78.5 million. Under the terms of the merger agreement, unanimously approved by the boards of directors of both companies, shareholders of Slippery Rock will be entitled to elect to receive $28.00 in cash or 1.41 common shares of F.N.B. per share of Slippery Rock common stock. The merger agreement allocation procedures provide for the exchange of 15 percent of Slippery Rock shares for cash, and the remaining Slippery Rock shares exchanged for F.N.B. common stock. Based upon a $28.00 per share value, the transaction price represents 243% of Slippery Rock's book value per share. It is anticipated that the merger will increase F.N.B.'s earnings per share in 2005 and add to regulatory capital ratios. "This merger is a positive step for both F.N.B. and Slippery Rock. For over a century, we have been an important part of the communities of Western Pennsylvania," said F.N.B.'s President and Chief Executive Officer Stephen J. Gurgovits. "When this merger is complete, F.N.B. will have more banking offices in Western Pennsylvania than any other community banking company headquartered in the state. Further, Slippery Rock's market area overlaps with our own and is growing at rates faster than that of Pennsylvania as a whole. We believe that this combination creates tremendous opportunities and value for our shareholders, customers, employees and communities." William C. Sonntag, Slippery Rock Financial Corporation's President and Chief Executive Officer, said, "We are pleased to be joining F.N.B. Corporation. Our companies have long been friendly competitors and we share a common vision with regard to customer service. This transaction provides our shareholders with significant immediate value, as well as the opportunity to participate as shareholders in a larger institution. The merger improves our ability to serve our customers, and expands career opportunities for our employees. We consider this a good transaction for all of our constituencies."
