(1)     On January 18, 2011, the Board of Directors (“Board”) of First Horizon National Corporation (the “Company”) elected Vicky B. Gregg to the Board, effective immediately. Ms. Gregg also has been elected to the Board of Directors of First Tennessee Bank National Association (the “Bank”). Ms. Gregg will stand for election to the Board of the Company by the shareholders at the April 2011 annual meeting.

Ms. Gregg is the Chief Executive Officer of BlueCross BlueShield of Tennessee (BCBST), a provider of group and individual health insurance plans, products, and services headquartered in Chattanooga, Tennessee. Ms. Gregg has been with BCBST since 2003. Prior to joining BCBST, Ms. Gregg served as Regional Vice President of Humana Inc. in Kentucky and Ohio.

(2)     There are no arrangements or understandings between Ms. Gregg and any other person concerning her selection to be elected to the Board of the Company.

(3)     Ms. Gregg has been appointed to serve on the Audit Committee of the Company’s Board.

(4)     The Company, the Bank, and the subsidiaries of each, as applicable, have entered into lending transactions and/or other banking or financial services transactions in the ordinary course of business with the Company’s executive officers, directors, nominees, their immediately family members and affiliated entities, and the persons of which we are aware that beneficially own more than 5 percent of our common stock, and we expect to have such transactions in the future. Such transactions were made in the ordinary course of business, were made on substantially the same terms, including interest rates and collateral, as those prevailing at the time for comparable transactions with persons not related to the Company, and did not involve more than the normal risk of collectability or present other unfavorable features.

(5)     Ms. Gregg will be eligible to participate in the Company’s active compensation plans and programs for non-employee directors. Additional information concerning the Company’s plans and programs for non-employee directors is provided in the following previously-filed material, which is incorporated into this item by reference: the “Director Compensation” section of the Company’s proxy statement for the 2010 annual meeting of shareholders appearing on pages 76-84. Ms. Gregg was elected in January at the outset of the regular January meeting and she attended that meeting as a director; accordingly under the Company’s Director Policy she will receive one-fourth of a normal annual grant of restricted stock units for the year 2010-2011. That pro-rated RSU grant will have a grant-date value of $11,250 and will vest later in 2011 in accordance with the Policy.

For several years Ms. Gregg has served on the Bank’s regional board in the Chattanooga market. As such she previously has received compensation in the ordinary course of providing those services. She previously elected to defer some of that compensation under older, discontinued stock option deferral plans, and she continues to hold long-term stock options granted in connection with those deferrals. Regional board members who also serve on the Board of the Company are paid regional board meeting attendance fees by the Company at the customary rate for the applicable market, subject to a $500 per meeting cap. The meeting fee for the Chattanooga regional board currently is $400 per meeting.

(e) Compensatory Arrangements of Certain Officers

On January 18, 2011, the Compensation Committee of the Company’s Board took certain actions related to the compensation of current executive officers who are named in the executive compensation disclosures of the Company’s 2010 proxy statement (“2009 Named Officers”). Among other things, the Committee changed the salary rates for the 2009 Named Officers for 2011. The cash salaries of 2009 Named Officers were not changed from 2010 rates, but the amounts of salary paid in the form of Salary Stock Units (“SSUs”) were reduced for each such Officer for 2011. In addition, SSUs credited to those Officers in 2011 will be subject to a service-vesting requirement. Such a requirement previously had not been permitted while the Company participated in the U.S. Treasury’s TARP program, but that participation ended late in 2010.

The SSU changes were approved as part of a broader set of revisions to the Company’s executive compensation components and mix. Those other revisions are expected to impact compensation opportunities and awards to be approved later in 2011 under existing plans.

Cash and SSU salary rates are subject to adjustment, and the SSU program is subject to substantive amendment or termination, by the Compensation Committee at any time.
