of First Tennessee National Corporation (the Corporation"),
Forms 3, 4 and 5 and any and all amendments thereto in
accordance with Section 16(a) of the Securities Exchange
Act of 1934, as amended (the "Exchange Act"), and the
rules thereunder; and

(2)  do and perform any and all acts on behalf of the
undersigned which may be necessary or desirable to

(3)  take any other action of any type whatsoever in
