The following joint press release was issued by F.N.B. Corporation and Slippery
Rock Financial Corporation on May 6, 2004.

           F.N.B. CORPORATION AND SLIPPERY ROCK FINANCIAL CORPORATION
                      ANNOUNCE DEFINITIVE MERGER AGREEMENT

HERMITAGE AND SLIPPERY ROCK, PA - (May 6, 2004) F.N.B. Corporation ("F.N.B.")
[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."

Pending receipt of regulatory approvals and the approval of Slippery Rock
shareholders, officials expect the transaction to be completed during the fourth
quarter of 2004. As part of the agreement, two members of the Slippery Rock
board of directors will be added to the board of First National Bank of
Pennsylvania.
