 deferred share unit award with respect to Fifth Third common stock, with the numbers of shares underlying such award adjusted based on the exchange ratio, and otherwise subject to the same terms and conditions as applied to the corresponding 
 Comerica award in effect immediately prior to the effective time.                                                                                                                                                                                 |

Pursuant to Comerica’s equity incentive plan and the award agreements thereunder, if an executive officer’s employment is terminated by Comerica without cause or by the executive officer for good reason (each as defined in the equity incentive plan) within 24 months following a change in control, all Comerica equity awards then held by such executive officer would fully vest upon such termination of employment. These “double trigger” vesting provisions applicable to Comerica equity awards will continue to apply after such awards are converted to the Assumed Options and Assumed RSU Awards at the effective time. For an estimate of the amounts that would be realized by each of Comerica’s named executive officers on the Assumed Closing Date in respect of their Comerica equity awards that are unvested and outstanding on such date, see the section entitled “— Quantification of Potential Payments and Benefits to Comerica’s Named Executive Officers in Connection with the Mergers” below. The estimated aggregate value of the unvested Comerica equity awards (along with accrued but unpaid dividend equivalents) held by the thirteen executive officers who are not named executive officers is $23,347,822 (the value of Comerica PSU Awards were calculated assuming that actual performance is equal to target performance for purposes of this quantification). All Comerica equity awards granted to its non-employeedirectors are fully vested upon grant. Change-in-ControlAgreements Comerica has entered into a change in control agreement (a “CIC Agreement”) with each of its executive officers. Under the CIC Agreements, each Comerica executive officer will be eligible for the following change-in-controlseverance benefits if the executive officer’s employment is terminated by Comerica without cause or by the executive officer for good reason (each as defined in the applicable CIC Agreement) within 30 months following a change in control:
