POWER OF ATTORNEY


KNOW ALL MEN BY THESE PRESENTS, that I, D. Stephen Martz, a Director of F.N.B.
Corporation, a corporation organized and existing under the laws of the State of
Florida, do constitute and appoint James Orie, David Mogle, Scott Free, Vince
Calabrese and Brian Lilly as my true and lawful attornies-in-fact, 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
attornies-in-fact deems appropriate, hereby ratifying and confirming all that
said attornies-in-fact may do or cause to be done by virtue hereof.
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 my hand and seal this 22nd day of
January, 2008




_D. Stephen Martz_
