             F.N.B. COMPLETES ACQUISITION OF SOUTHERN EXCHANGE BANK;
           BRANCHES WILL OPERATE UNDER FIRST NATIONAL BANK OF FLORIDA

NAPLES, FL, March 31 - F.N.B. Corporation (Nasdaq: FBAN) today announced that it
has completed the acquisition of Charter Banking Corp., the holding company for
Southern Exchange Bank based in Tampa, Florida. The merger solidifies F.N.B.'s
position as the largest bank holding company headquartered in the state of
Florida.

"We are very excited about our entry into the Tampa market," said Gary Tice,
President and Chief Executive Officer of F.N.B. Corporation. "With these new
offices, we will significantly increase the number of commercial loans and
develop consumer and small business relationships. We also will introduce new
products and services, including insurance, mutual funds, retail brokerage,
online banking and wealth management."

Southern Exchange's 18 full-service banking offices in Hillsborough and Pinellas
counties will be converted and operate as branches of F.N.B. affiliate
First National Bank of Florida. The branch integration is scheduled to be
completed during the fourth quarter of 2003. As a result of this combination,
First National Bank of Florida will have assets of approximately $3.4 billion
and 61 full-service financial centers throughout the state.

"We believe that we have acquired an excellent branch network on which to
build," said Garrett S. Richter, President and Chief Executive Officer of
First National Bank of Florida. "Southern Exchange Bank has a reputation as a
well managed and profitable institution. We welcome their customers to our
unique style of community banking."



In keeping with F.N.B.'s community banking philosophy, most key customer contact
employees will be retained. David A. Straz Jr., Chairman of Southern Exchange
Bank and the sole shareholder of Charter Banking Corp., has joined the boards
of directors of both F.N.B. Corporation and First National Bank of Florida,
and bank President and CEO Richard Weatherby will stay on in a leadership role
as Executive Vice President.

"We are delighted about our affiliation with F.N.B.," Straz said. "Together,
we will be able to better serve our customers with more financial products and
services, increased lending limits and more convenient branch locations.
We also will be better suited to provide an expanded array of products,
including insurance and wealth management."

This is the latest in a series of acquisitions in Florida by F.N.B. Corporation
and significantly expands the company's footprint in that state. With this
affiliation, First National Bank of Florida will have a significant presence
in many of Florida's most attractive retail banking markets, including Naples,
Marco Island, Bonita Springs, Fort Myers, Cape Coral, Venice, Sarasota,
Clearwater, St. Petersburg, Tampa and Orlando.

This marks F.N.B. Corporation's 11th bank acquisition in Florida since 1997.
The acquisition of Southern Exchange Bank is the company's largest to date
in that state.

headquartered in Naples, Florida. The company currently owns and operates
community banks, insurance agencies, a consumer finance company and
First National Trust Company. It has offices located in Florida, Pennsylvania,
