         F.N.B. CORPORATION DECLARES SPIN-OFF RECORD DATE AND
          DATE OF DISTRIBUTION, SUBJECT TO CERTAIN CONDITIONS

NAPLES, FL, December 18 - F.N.B. Corporation (NYSE: FNB), a diversified
financial services company, today announced that its Board of Directors has
declared, subject to satisfaction of certain conditions, a record date of
December 26, 2003, and an effective date of January 1, 2004, for the pending
spin-off of its Florida operations, which will operate as a separate company
to be called First National Bankshares of Florida, Inc.

Each F.N.B. shareholder of record as of the close of business on the record
date will receive, as of 12:01 a.m. on January 1, 2004, one share of First
National Bankshares common stock for each share of F.N.B. common stock held
on the record date. The spin-off is subject, however, to the receipt of all
regulatory approvals and the declaration of effectiveness by the Securities
and Exchange Commission of the Form 10 Registration Statement filed by First
National Bankshares. F.N.B. will publicly announce on or prior to December 26,
2003, whether the conditions have been satisfied, and if either of the
conditions has not been satisfied, F.N.B. will set a new record date and
effective date for the spin-off. F.N.B. expects that the conditions will be
satisfied by December 26, 2003.

F.N.B. has received a private letter ruling from the IRS confirming the tax-free
nature of the spin-off for U.S. federal income tax purposes. F.N.B. is traded
on the New York Stock Exchange (NYSE) under the ticker symbol "FNB." First
National Bankshares common shares have been cleared for trading on the NYSE
under the new symbol "FLB."

Once the spin-off is completed, F.N.B. Corporation intends to relocate its
headquarters to Hermitage, Pennsylvania, where it will focus on the well-
established Pennsylvania and Ohio operations. First National Bankshares will
maintain corporate headquarters in Naples, Florida, where it will focus on
expanding in the fast-growing Florida market.




The spin-off is expected to unlock shareholder value by allowing each company
to develop and implement a strategic plan that fits its markets and operations.
It also will enable the investment community to more easily value the two
companies. The Pennsylvania company is expected to be a high-performing, high
dividend paying entity with a valuation based on the dividend payout and a
multiple of earnings in line with its peers. The Florida company will be
positioned for growth in one of the country's most attractive areas. As such
its stock should trade in line with its peers. The combined cash
dividend for the companies is expected to increase by approximately 25%
for 2004.

F.N.B. Corporation owns and operates community banks, insurance agencies,
a consumer finance company and First National Trust Company. The company has
approximately $8.3 billion in total assets with offices in Pennsylvania, Ohio,
Florida and Tennessee.
