PERSONAL AND CONFIDENTIAL STOCK OPTION AGREEMENT UNDER THE AMSOUTH BANCORPORATION 2006 LONG TERM INCENTIVE COMPENSATION PLAN

Exhibit 99.6

PERSONAL AND CONFIDENTIAL

STOCK OPTION AGREEMENT

UNDER THE

AMSOUTH BANCORPORATION 2006 LONG TERM INCENTIVE

COMPENSATION PLAN

You are hereby informed that Regions Financial Corporation, on April 24, 2007, granted you options to purchase shares of its common stock as specifically detailed in the enclosed Notice of Grant of Stock Options. The option price is $35.07 per share, which was the Fair Market Value of each share of common stock on the date of grant. The value of these options will be determined by the amount of any appreciation in the price of Regions common stock in the future, which in turn is dependent upon our ability to continue performing well as a company.

Your option was granted to you under the AmSouth Bancorporation 2006 Long Term Incentive Compensation Plan (the Plan), the terms and conditions of which are incorporated in this document by reference as if fully set forth herein. The Plan is administered by the Compensation Committee (the “Committee”) of the Board of Directors. This document sets out some of the specific terms of your award and constitutes the Award Agreement required by the Plan. You should retain it for future reference. References to defined terms in the Plan are capitalized in this Award Agreement. You should also pay particular attention to the Plan and its prospectus since they set forth other provisions applicable to this grant of Stock Options. The prospectus for the Plan, the Plan document itself, and a Reference Outline provide you helpful information and explanations related to your grant. These documents are obtainable by logging on to the Executive Web Site via your office personal computer at http://hrweb1/executive/. If you do not have access to the Executive Web Site or to a personal computer and you would like copies of the documents, please contact Executive Compensation at (205) 801-0400. You should note that in the event of any conflict or inconsistency between the provisions of this Award Agreement and the terms and conditions of the Plan, the terms and conditions of the Plan will control.

Your options may consist of both “incentive stock options” which qualify for certain favorable tax consequences for you, as well as “nonqualified stock options” which do not qualify for those tax consequences. For a description of the tax consequences to you, please refer to the Plan prospectus. One important difference between incentive stock options and nonqualified stock options is that upon the exercise of a nonqualified option you are automatically deemed to incur taxable income at ordinary income tax rates. Please consult your tax advisor to determine how these differences affect you.

The type of options that have been granted to you, and the dates on which they become exercisable (i.e., “vest”), are set forth in the enclosed Notice of Grant of Stock Options.

The last day on which any of these options can be exercised (assuming they are exercisable at the time in accordance with the other terms and conditions of this Award Agreement and the Plan) is April 23, 2017. The period of time from April 24, 2007 to April 23, 2017 is known as the “option period”. Your options will become immediately exercisable in full if your employment ceases by reason of death or Disability or if a Change in Control occurs while you are employed by Regions. In the event of termination of your employment by retirement at or after age 55 prior to November 30, 2007, your options will be forfeited. In the event of termination of your employment by retirement at or after age 55 on or after November 30, 2007, unvested options will become immediately exercisable. The amount of time you have to exercise your exercisable options after these and certain other events is set forth in the following table.

If you die during the one year period applicable to Disability or th
