ITEM 1.01 ENTRY INTO A MATERIAL DEFINITIVE AGREEMENT.

In September 2008, Comerica Incorporated ("Comerica") announced that Dennis J. Mooradian, Executive Vice President, Wealth and Institutional Management, planned to retire in the first quarter of 2009. Mr. Mooradian has now further announced that his retirement date will be February 28, 2009. On February 25, 2009, Comerica issued a press release regarding this upcoming retirement, which is attached hereto as Exhibit 99.1.

In connection with Mr. Mooradian's retirement, Comerica and Mr. Mooradian entered into a restrictive covenants and general release agreement (the "Agreement") dated February 20, 2009. The Agreement specifies that Mr. Mooradian's employment will terminate February 28, 2009. Under the terms of the Agreement, Mr. Mooradian provides a general release of claims in favor of Comerica and its affiliates and agrees to be bound by certain restrictive covenants (including non-disparagement, cooperation, confidentiality and two year non-competition and non-solicitation covenants).

In consideration of these covenants and the release, the Governance, Compensation and Nominating Committee of the Board of Directors approved the accelerated vesting of Mr. Mooradian's restricted Comerica stock as of his separation date and determined that his separation will qualify as a "retirement" so that his unvested stock options outstanding as of the separation date, other than those granted in the calendar year of his separation date, will continue to vest pursuant to the regular vesting schedule applicable to such options, and any outstanding vested options will not expire until the end of their respective regular term.

This summary of the Agreement is qualified in its entirety by the terms of the Agreement, a copy of which is being filed herewith as Exhibit 10.1.
