ITEM 5.  Other Events and Regulation FD Disclosure

         First Tennessee National Corporation ("Corporation") announced today
that management has been delegated the authority within defined limits to
purchase up to the total principal amount outstanding of the Corporation's 6.75%
November 2005 subordinated debt ($75 million). Since this outstanding debt issue
is in the last half of its term, it provides only limited regulatory capital
benefit and will be replaced with short-term market rate funds.
         Today a tender offer was commenced to purchase this debt issue at a
price reflecting a formula-driven premium to its par value. Using the formula
with the appropriate spread over the benchmark rate as of 1:30 pm CDST yesterday
(07/29/03), a premium of 10.8% over par would be paid for the Corporation's
debt. Because the Corporation is offering to pay a premium, the tender offer, if
completed, will result in a current charge to earnings. The amount of the charge
will primarily depend on the amount of the debt issue tendered and purchased in
the offer, which is estimated to be between 60 percent and 90 percent of the
total principal amount outstanding.
         Purchase activities are expected to take place during third quarter
2003 and will be managed by FTN Financial Securities Corp., a subsidiary of
First Tennessee Bank National Assoc.
         This item contains forward-looking statements involving significant
risks and uncertainties. A number of factors could cause actual results to
differ materially from those in the forward-looking information. Those factors
are outlined in the recent earnings press release and in more detail in the most
current 10-K and 10-Q. The Corporation disclaims any obligation to update any of
the forward-looking statements that are made from time to time, to reflect
future events or developments.
