                   F.N.B. Corporation is a bank holding company head-
         quartered in Hermitage, Pennsylvania, with $1.7 billion in
         assets. It operates six banks and a consumer finance subsidiary
         through 93 offices in Pennsylvania, eastern Ohio and southwest
         New York. The company recently announced record earnings for
         1995 of $18.1 million, $2.00 per share primary and $1.90 fully
         diluted, which represents a 34% increase over 1994.

                   Southwest Banks, Inc., a holding company headquar-
         tered in Naples, Florida, operates two banking subsidiaries,
         First National Bank of Naples with five locations in Collier
         County and Cape Coral National Bank in Lee County with two
         locations.  At December 31, 1995, its assets totaled $386 mil-
         lion which represents a 46% growth rate for the year.  Addi-
         tionally, Southwest recently reported record earnings of $1.7
         million or $.44 per share for the year 1995, an increase of
         162% over last year.

                   Gary L. Tice, Chairman, President and Chief Executive
         Officer of Southwest Banks, Inc., enthusiastically remarked,
         "The transaction represents a substantial premium over current
         market and book values and an exciting business opportunity,
         especially considering the historical operating philosophy of
         F.N.B. Corporation.  F.N.B. provides its affiliates an operat-
         ing environment which will allow us to continue our commitment
         to superior customer service.  This situation is unlike recent
         mergers which have resulted in sign changes, product changes,
         layoffs, branch closings and reduced customer service.  Addi-
         tionally, F.N.B. Corporation provides a strong source of capi-
         tal which will permit our company to continue pursuing a prof-
         itable growth strategy.  In my opinion, there has never been a
         more natural, compatible and complimentary affiliation with two
         companies relative to common values, operating philosophy,
         strategic needs and management personalities."  Tice is a
         native of Sharpsville, Pennsylvania, and was once an officer of
         First National Bank of Pennsylvania, the lead bank of F.N.B.
         Corporation.  Tice added, "In addition to realizing a premium
         on their stock ownership, shareholders will benefit from divi-
         dends paid by F.N.B. Corporation."

         Southwest Banks has not paid cash dividends. F.N.B. Corporation
         recently increased its regular dividend on common stock to $.64
         on an annual basis, which represents a 3% yield.

                   Commenting on the proposed merger, Peter Mortensen,
         Chairman and President of F.N.B. Corporation, said, "The
         affiliation with Southwest Banks provides a unique opportunity
         to employ our growing capital and greatly increases the fran-
         chise value of the Company.  Further, we are fortunate to have
         an in-depth knowledge of Southwest Banks and its strong manage-
         ment team.  Finally, in contrast to our traditional stable mar-
         ket areas, southwest Florida is one of the fastest growing mar-
         kets in the U.S."  Mortensen is one of the founders of
         Southwest Banks, Inc. as well as its lead bank, First National
         Bank of Naples and has served as a director of both entities
         since their formation in 1988.  F.N.B. Corporation has owned
         approximately 5% of Southwest Banks' stock for several years.
         The management of both companies have a similar credit philoso-
         phy having jointly financed numerous projects over the years
         both in Florida and Pennsylvania.

                   As a result of the merger, Southwest Banks, Inc. will
         be an affiliate of F.N.B. Corporation.  Its banks will retain
         their individual identity and high customer service standards.
         Gary L. Tice will remain Chief Executive Officer of Southwest
         Banks and will become an Executive Vice President and Director
         of F.N.B. Corporation.  Two other directors of Southwest Banks
         will be invited to join the F.N.B. Corporation's Board.

                   On a proforma consolidated basis, measured at
         December 31, 1995, F.N.B. Corporation would have total assets
         of $2.1 billion, total deposits of $1.8 billion and total
         Shareholders' Equity of $174 million.  F.N.B. Corporation and
         Southwest Banks would each continue to be characterized as
         "well capitalized" by all regulatory standards.

                   Mortensen added, "The transaction will create an
         acceptable level of earnings dilution, about 6% in the first
         year.  Based on our advisors' analyses considering certain
         assumptions and expectations, it is anticipated that the impact
         will become accretive approximately

         eighteen months after closing.  This accretion should increase
         rapidly considering the favorable growth in Southwest Banks'
         market compared to our more mature market area."

                   In connection with the merger, Southwest Banks, Inc.,
         is granting an option to F.N.B. Corporation to acquire up to
         19.9% of its stock exercisable at a price of $15.00 per share
         only if certain conditions are met.  The merger requires
         approval by Southwest Banks, Inc. shareholders as well as vari-
         ous regulatory authorities.  Closing is expected in early 1997.
         The investment banking firm of McConnell, Budd & Downes, Inc.
         is advising F.N.B. Corporation and Robinson-Humphrey Company,
         Inc. is advising Southwest Banks, Inc. in this transaction.

                   F.N.B. Corporation's common stock trades on NASDAQ
         under the symbol FBAN.  The average of its bid and asked price
         last Friday was $21.125.  Southwest Banks, Inc. trades in the
         over-the-counter market using the symbol SWBA and was quoted on
