                                                      RESTRICTED STOCK AGREEMENT

Date:
      --------------

Participant:
             --------------

Number of Shares:
                  ----------------

     Restricted Stock Agreement ("Agreement") made as of the date specified
above by and between First Horizon National Corporation (the "Company"), acting
with the prior approval of the Compensation Committee (the "Committee") of the
Board of Directors and the employee whose name is specified above, who is an
employee of the Company, or one or more of its subsidiaries, (the
"Participant").

     In consideration of the covenants hereinafter set forth, the Company and
the Participant agree as follows:

     1. Award. Pursuant to the terms of the First Horizon National Corporation
2003 Equity Compensation Plan (the "Plan"), the Company hereby grants to the
Participant the number of shares specified above (the "Shares") of common stock
of the Company, par value $0.625 per share (the "Common Stock"), subject to the
Restrictions and other conditions hereinafter set forth. So long as any Shares
are subject to the Restrictions set forth in Section 3 hereof, such Shares shall
be deemed to be, and shall be referred to herein as, Restricted Shares.

     2. Certificates. Each certificate evidencing Restricted Shares shall be
deposited with the Treasurer of the Company, accompanied by a stock power in
blank executed by the Participant, or shall be held in book-entry form at the
Company's transfer agent, and shall bear the following legend:

     "This certificate and the shares of stock represented hereby are subject to
the terms and conditions (including the risk of forfeiture and restrictions on
transfer) contained in the First Horizon National Corporation 2003 Equity
Compensation Plan and a Restricted Stock Agreement entered into between the
registered owner and First Horizon National Corporation. Release from such terms
and conditions shall occur only in accordance with the provisions of such Plan
and Agreement, a copy of each of which is filed with the Secretary of First
Horizon National Corporation."

     3. Restrictions. During applicable periods of restriction determined in
accordance with Section 5 of this Agreement, Restricted Shares, and the right to
vote such Shares and to receive dividends thereon, may not be sold, assigned,
transferred, exchanged, pledged, hypothecated or otherwise encumbered, and shall
be subject to the risk of forfeiture contained in Section 4 of this Agreement
(such limitations on transferability and risk of forfeiture being collectively
called the "Restrictions"), but the Participant shall have all other rights of a
stockholder, including, but not limited to, the right to vote and receive
dividends on Restricted Shares.

     4. Forfeiture of Restricted Shares. In the event that the Participant (a)
voluntarily terminates his employment with the Company (including its
subsidiaries), (b) is discharged from employment with the Company (including its
subsidiaries) as a result of his failure (not caused by death or Disability (as
defined in the Plan)) to perform the duties of his position faithfully and to
the best of his ability, or (c) except in connection with a Change in Control as
described below, is reassigned to a position which, in the opinion of the
Committee, reduces the Participant's opportunity to make an impact upon the
profitability of the Company through his/her decisions, actions and counsel (the
events described in the foregoing clauses (a), (b), and (c) being called herein
"Events of Forfeiture"), all Shares which at the time are Restricted Shares
shall be forfeited by the Participant to the Company without payment of any
consideration by the Company, and neither the Participant, nor any successor,
heir, assign or personal representative of the Participant, shall have any
further right to or interest in such Restricted Shares or any certificate or
certificates evidencing them. Notwithstanding anything herein to the contrary,
if a Change in Control







(as defined in the Plan) occurs and if, prior to the date on which the Change in
Control occurs, the Participant's employment with the Company is terminated or
the Participant is reassigned to a position within the meaning of Section 4(c)
and if it is reasonably demonstrated by the Participant that such termination of
employment or reassignment of position (I) was at the request of a third party
who has taken steps reasonably calculated to effect a Change in Control or (ii)
otherwise arose in connection with or in anticipation of a Change in Control,
then for all purposes of this Agreement such termination or reassignment shall
not be deemed an Event of Forfeiture, no Shares which at the time are Restricted
Shares shall be forfeited by the Participant to the Company upon such
termination or reassignment, and all Restrictions with respect to such Shares
shall lapse upon the Change in Control.

     5. Lapse of Restrictions.

     (a) Subject to clauses (b) and (c) of this Section 5, the Restrictions
shall lapse with respect to Restricted Shares in accordance with the following
schedule:



Date                                Number of Shares
- ----                                ----------------
                                 
[tenth anniversary of grant date]   All Shares


     (b) If the Participant's employment with the Company (including its
subsidiaries) ends as a result of any event other than an Event of Forfeiture,
all Restrictions shall forthwith lapse as to all Restricted Shares.

     (c) Notwithstanding the provisions of clause (a), but subject to clause (b)
of this Section 5, the Restrictions shall lapse with respect to the Restricted
Shares in accordance with the following schedule if the performance criteria
established by the Committee for the performance period at the beginning of such
period (or on the date hereof for the first and second performance periods) are
achieved:



Performance Period                                      Number of Shares   Date of Lapse
- ------------------                                      ----------------   -------------
                                                                     
[three calendar years beginning year of grant]          __________         [April of year following perf. period]
[three calendar years beginning 1st year after grant]   __________         [April of year following perf. period]
[three calendar years beginning 2nd year after grant]   __________         [April of year following perf. period]


Each lapse of Restrictions provided for in this clause (c) is noncumulative. In
other words, if performance criteria for any performance period are not
achieved, Restrictions with respect to the indicated Restricted Shares shall not
lapse until the date specified in clause (a).

     (d) Upon lapse of the Restrictions in accordance with this Section 5 or
Section 7, new certificates evidencing the Shares with respect to which the
Restrictions have lapsed, without the foregoing restrictive legend, shall be
issued to the Participant or his legal representative, against cancellation of
the legended certificates, or, if applicable, the Company's transfer agent shall
be directed to remove the legend from Shares held in book-entry form. Each such
new certificate, and any Shares held in book-entry form, shall bear a legend
reflecting any restrictions upon the transferability of such Shares imposed by
law, such as the Securities Act of 1933.

     6. Withholding Requirements. Whenever payments hereunder are to be made in
cash, or Restrictions lapse with respect to Restricted Shares, the Company shall
have the right to withhold from sums due to the Participant (or to require the
Participant to remit to the Company) an amount sufficient to satisfy any
federal, state or local withholding tax requirements prior to making such
payments or delivering any certificate evidencing such Shares.

     7. Change in Control. Notwithstanding anything herein to the contrary, all
Restrictions with respect to the Restricted Shares imposed by the Plan or this
Agreement shall lapse immediately upon a Change in Control (as defined in the
Plan).

     8. Tax Elections. The Participant agrees not to make an election in
accordance with Section 83(b) of the Internal Revenue Code of 1986, as amended,
to include in his gross income for federal income tax purposes the value of the
Restricted Shares in the year in which this Agreement is made.


                                       2







     9. Deferrals. Section 3(A)(vii) of the Plan permits certain participants,
whose Agreement so provides, to make deferral elections with respect to an award
under the Plan. Participant is eligible to make a deferral election pursuant to
Section 3(A)(vii) of the Plan with respect to one or more deferral periods by
complying with the procedures established by the Committee.

     10. Effect on Employment. Nothing contained in this Agreement shall confer
upon the participant the right to continue in the employment of the Company
(including its subsidiaries) or affect any right which the Company (including
its subsidiaries) may have to terminate the employment of the Participant.

     11. Amendment. This Agreement may not be amended except with the consent of
the Committee and by a written instrument duly executed by the Participant and
the Company.

     12. Binding Effect. This Agreement shall be binding upon and shall inure to
the benefit of the parties hereto and their heirs, personal representatives,
successors and assigns.

     IN WITNESS WHEREOF, each of the Company and the Participant has executed
and delivered this Agreement as of the day and year first above written.
