POWER OF ATTORNEY


KNOW ALL MEN BY THESE PRESENTS, that I, Vincent J. Delie, Jr., an Executive
Officer 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 30th day of May,
2008.
