STATE OF PENNSYLVANIA

COUNTY OF MERCER





POWER OF ATTORNEY

	KNOW ALL MEN BY THESE PRESENTS, that commencing
January 1, 2004, I, Peter Mortensen, a Director of F.N.B. Corporation, a
Florida Corporation, do constitute and appoint Brian Lilly, Tito Lima,
David B. Mogle and James G. Orie my true and lawful attornies-in-fact, who
may act individually under this Power of Attorney with full power of
substitution, for me in any and all capacities, to sign, pursuant to the
requirements of Section 16 of the Securities Exchange Act of 1934, as
amended, any report on Form 3, Form 4, or Form 5, respecting the securities
of F.N.B. Corporation and to file the same with the Securities and Exchange
Commission, together with all exhibits thereto and other documents in
connection therewith, and to sign on my behalf and in my stead, in any and
all capacities, any amendments to said reports, incorporating such changes
as said attorney-in-fact deems appropriate, hereby ratifying and confirming
all that said attorney-in-fact may do or cause to be down by virtue hereof
(hereinafter referred to as "F.N.B. SEC Section 16 Filings"), and hereby
revoking any existing Power of Attorney which I may have previously granted
concerning my F.N.B. SEC Section 16 Filings, effective January 1, 2004.



	The authority of my attorney-in-fact shall be effective until I
expressly revoke it and file same with the Securities and Exchange
Commission.


	I acknowledge that I have granted this power of
attorney solely to make it more convenient for me to comply with my
reporting responsibilities under Section 16 of the Exchange Act, that my
granting of this power of attorney does not relieve me of any of my
responsibilities to prepare and file on a timely basis all reports that I
may be required to file under said Section 16, and that neither F.N.B.
Corporation nor my attorney-in-fact has assumed, or shall be deemed to
assume, any of my responsibilities in that regard.


	IN WITNESS
WHEREOF, I have hereunto set in my hand and seal this 15th day of December,
2003.
