ITEM 1.01.      ENTRY INTO A MATERIAL DEFINITIVE AGREEMENT

On February 15, 2007, a subsidiary of First Horizon National Corporation entered into a Settlement Agreement (“Settlement Agreement”) to settle a class action lawsuit filed by David and Holly McLean and Roger and Eugenia Jones (in the case of David and Holly McLean, et al. v. First Horizon Home Loan Corporation) relating to the charging of certain loan origination fees (the “McLean Suit”). The McLean Suit is described in Note 9 to the financial statements included in the Corporation’s Form 10-Q for the quarter ended September 30, 2006. With some exceptions described in the Settlement Agreement, the plaintiff class members are the persons who obtained a second mortgage loan on Missouri property from McGuire Mortgage Company, a company acquired by the Corporation, or First Horizon Home Loan Corporation’s McGuire Mortgage division on or after November 16, 1994 through and including April 13, 2005. First Horizon Home Loan Corporation is an indirect, wholly-owned subsidiary of the Corporation. The Settlement Agreement reflects the definitive terms of the settlement, which is subject to final court approval. A fairness hearing, at which such final approval is to be considered, presently is anticipated to be held by the court later this year. If the settlement and Settlement Agreement are approved, the Corporation, through its subsidiaries, will provide benefits to the class members who choose to participate in the settlement. Excluding administrative expenses, certain incentive payments, and the Corporation’s legal expenses, the Corporation’s payments under the Settlement Agreement will be no more than $36.3 million, from which shall be paid amounts to participating class members and amounts that the court awards, if any, for class counsel fees and costs, all as described in the Settlement Agreement. Payment is not due until final approval of the settlement has occurred and all appeals have run or been favorably resolved. The Settlement Agreement is filed with this Report as Exhibit 10.10.

The Settlement Agreement provides for the dismissal with prejudice of the McLean Suit and a broad release of all claims by plaintiffs arising out of or relating in any way to the origination of any loan subject to the McLean Suit. Servicing disputes have been excepted from the release, and origination claims other than Missouri statutory claims have been excepted from the release if raised purely as a defense to foreclosure against someone other than the Corporation or its subsidiaries. The Corporation has certain rights to withdraw from the settlement, as provided in the Settlement Agreement.
