LARRY B. MARTIN
RETIREMENT AGREEMENT

          This Agreement is made by and between Larry B. Martin (“Mr. Martin” or
“you”) and First Horizon National Corporation, its predecessors, successors,
assigns, subsidiaries, parents, affiliates, and their respective directors,
officers, employees and agents, attorneys and representatives, both past,
present, or future (“the Company”). This arrangement is offered in recognition
of your years of service with the Company and is accompanied with the Company’s
hope that it will assist you during the transition period that follows.

          You will have up to 21 days to evaluate this Agreement. After signing
this Agreement, you have seven days during which you may revoke your decision.
The evaluation period will end on the earlier of the date you sign this
agreement or on March 31, 2006.

          The elements of the retirement agreement are these:

          1.     Agreement:

          Your signature at the conclusion of this document represents your
knowing and voluntary acceptance of this agreement. You acknowledge that you
have not been pressured in any way to sign this Agreement and that you have
executed it of your own free will. This Agreement should be returned to Jerrie
Lytton, Senior Vice President & Employee Services Relationship Manager, 2112
North Roan Street, 4th Floor, Johnson City, Tennessee 37601, after you have
fully executed it.

          2.     Consideration:

          In consideration of your release as set forth below and your
retirement on June 30, 2006, the Company will provide you with the following.
You acknowledge that you are not otherwise entitled to the consideration listed
in this section. In the event of your death prior to the payment of any of the
amounts set forth in this section, any payments for which a beneficiary has not
already been designated will be paid to your estate.

          (i)     Payment of one year’s base salary

          You will receive payment of one year’s base salary in the amount of
$482,000.00 less applicable taxes and deductions. This payment will be made in a
lump sum on the first available pay period after the effective date of your
retirement, provided that date is after the expiration of the 7-day revocation
period following your signing of this agreement.

          (ii)     Standard Pension Restoration Plan benefit

          You will receive a monthly non-qualified pension benefit in accordance
with the terms of the Company’s Pension Restoration Plan except that the company
will waive the requirement for working until age 65 to receive this benefit and
the first six monthly payments under this plan will be delayed and paid in a
lump sum six months after your retirement date to comply with tax code 409A.

          (iii)     Additional pension benefit payment

          You will receive a one time lump sum payment of $1,330,000.00 less
applicable taxes and deductions, which is the approximate present value of
adding five years to your actual service for the purpose of determining your
nonqualified pension benefit. This payment will be made on the first available
pay period six months after your retirement date and will not have any effect on
your FHNC qualified defined pension benefit. For purposes of calculating your
FHNC qualified defined pension benefit, you will not receive any additional
service credit beyond your actual years worked.

          (iv)     Restricted Stock

          Your restricted stock will vest upon retirement. The company retains
the right to withhold shares to meet tax withholding requirements.

          (v)     Annual Bonus

          You have received your annual bonus for 2005. You will not be eligible
for a bonus for 2006.

          (vi)     Long-term Incentive Plan (LTIP) Awards

          A percentage of currently outstanding LTIP awards will be paid per the
performance formula and at the same time they would have been paid if you had
not retired. All awards will be prorated based on full years worked during each
performance period to provide a percentage of the award for each performance
period. For example, you worked two full years of the three years in the
2004-2006 performance period, so you will receive two-thirds of the award after
adjustments are made to reflect corporate performance as provided by the
program. The payment of the 2004-2006 award will be made in the first quarter of
2007. Because you worked one full year during the 2005-2007 performance period,
you will receive one-third of the award for the 2005-2007 performance period.
The payment of the 2005-2007 award will be made in the first quarter of 2008.
Nothing contained herein should be construed to guarantee that an LTIP award
will be paid in either 2007 or 2008 if such payment is not warranted by Company
results in accordance with the terms and conditions of the program.

          (vii)     Director and Executive Deferred Compensation Plan

          Payments of benefits will commence upon attainment of age 65 as
originally contemplated upon enrollment in the plan.

          3.     Confidentiality and Non-Disclosure:

          In order to protect the legitimate interests of the Company, and its
subsidiaries, you agree that you will not disclose to others at any time in the
future, whether directly or indirectly, any information relating to the
Company’s business plans or other confidential business information and/or trade
secrets of the Company which you received or to which you were given access
during your employment with the Company. If such information is required to be
produced by law, court order or governmental authority, you must promptly notify
the Company of that obligation. You may not produce or disclose any such
information until the Company has (a) requested protection from the court or
other legal or governmental authority issuing the process and the request has
been denied, (b) consented in writing to such production or disclosure, or (c)
taken no action to protect its interest within ten (10) business days (or such
shorter period required by order of a court or other legal or governmental
authority) after receipt of your notice.

          If any part of this agreement is knowingly violated by you, then you
will be responsible for repayment of all sums paid to you pursuant to paragraph
2 of this agreement, in addition to all enforcement costs including, but not
limited to reasonable attorney’s fees.

          4.     Release and Waiver:
