Note on Filing History On October 21, 2003, First Horizon National Corporation ("FHNC" or the "Registrant") filed a registration statement on Form S-8 (File No. 333-109862), registering 3,000,000 shares of its common stock, par value $0.625 per share, for sale under Registrant's 2003 Equity Compensation Plan (as amended to date, the "Plan"). Registrant is filing this registration statement to register 1,000,000 additional shares of Registrant's common stock for sale under the Plan, which was amended February 17, 2004 (approved by the shareholders on April 20, 2004) to increase by 1,000,000 the number of shares authorized for issuance. PART I The Section 10(a) prospectus relating to the Plan is omitted from this Registration Statement pursuant to the Note to Part I of Form S-8. PART II INFORMATION REQUIRED IN REGISTRATION STATEMENT As permitted by Instruction E to Form S-8, the contents of Registrant's registration statement on Form S-8 (File No. 333-109862), which was filed October 21, 2003, covering shares for sale under the Plan, as updated below, are incorporated herein by reference. In addition to the foregoing, the following information is also included in this registration statement: Item 5. Interests of Named Experts and Counsel KPMG LLP, the Registrant's independent accountants, have no interest in the Registrant. The validity of original issue shares of $0.625 par value common stock of First Horizon National Corporation ("FHNC" or the "Registrant") to be issued pursuant to the Plan has been passed upon by Clyde A. Billings, Jr., Senior Vice President, Assistant General Counsel and Corporate Secretary of FHNC. On March 1, 2005, the number of shares, including options, beneficially owned by Mr. Billings was approximately 47,934 shares. Item 6. Indemnification of Directors and Officers Tennessee Code Annotated Sections 48-18-501 through 48-18-509 authorize a corporation to provide for the indemnification of officers, directors, employees and agents in terms sufficiently broad to permit indemnification under certain circumstances for liabilities (including reimbursement for expenses incurred) arising under the Securities Act of 1933, as amended. FHNC has adopted the provisions of the Tennessee statute pursuant to Article Six of its Bylaws. In addition, FHNC has a directors' and officers' liability insurance policy which provides coverage sufficiently broad to permit indemnification under certain circumstances for liabilities (including reimbursement for expenses incurred) arising under the Securities Act of 1933, as amended. 2 Tennessee Code Annotated, Section 48-12-102, permits the inclusion in the charter of a Tennessee corporation of a provision, with certain exceptions, eliminating the personal monetary liability of directors to the corporation or its shareholders for breach of the duty of care. FHNC has adopted the provisions of the statute as Article 13 of its charter. The shareholders of FHNC have approved an amendment to Article Six of the Bylaws pursuant to which FHNC is required to indemnify each director and any officers designated by the Board of Directors, and advance expenses, to the maximum extent not prohibited by law. In accordance with the foregoing, the Board of Directors is authorized to enter into individual indemnity agreements with the directors and such officers. Such indemnity agreements have been approved for all of the directors and certain officers. Item 8. Exhibits All Exhibits are listed in the Exhibit Index at the end of this Part II. Item 9. Undertakings (a) The undersigned registrant hereby undertakes: (1) To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement: (i) To include any prospectus required by Section 10(a)(3) of the Securities Act of 1933; (ii) To reflect in the prospectus any fact or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represents a fundamental change in the information set forth in the registration statement; (iii) To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement; Provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) do not apply if the registration statement is on Form S-3 or Form S-8, and the information required to be included in a post-effective amendment by those paragraphs is contained in periodic reports filed by the registrant pursuant to Section 13 or Section 15(d) of the Securities Exchange Act of 1934 that are incorporated by reference in the registration statement. (2) That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. 3 (3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering. (b) The undersigned registrant hereby undertakes that, for purposes of determining any liability under the Securities Act of 1933, each filing of the registrant's annual report pursuant to Section 13(a) or Section 15(d) of the Securities Exchange Act of 1934, (and, where applicable, each filing of an employee benefit plan's annual report pursuant to Section 15(d) of the Securities Exchange Act of 1934) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. (c) Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue. 4 SIGNATURES ---------- The Registrant.
