 by the executive officer for “good reason” (as such terms are defined in the relevant plans and agreements), in either case immediately following the mergers and on the Assumed Closing Date. |

The amounts indicated below are estimates based on multiple assumptions that may or may not actually occur or be accurate on the relevant date, including the assumptions described above, and do not reflect or attempt to forecast certain compensation actions that may occur before completion of the mergers, including any additional equity award grants, issuances or forfeitures that may occur prior to the effective time of the mergers following the date of this joint proxy statement/prospectus. As a result of the foregoing assumptions, which may or may not actually occur or be accurate on the relevant date, the actual amounts to be received by the executive officers and directors of Comerica may materially differ from the amounts set forth below. Treatment of Outstanding Comerica Equity Awards At the effective time, outstanding Comerica equity awards will be treated as follows, subject to all required withholding taxes:

| • |     | Comerica Stock Options: each outstanding and unexercised Comerica Stock Option, whether vested or                                                                                                                                                         
 unvested, shall, automatically and without any required action on the part of the holder thereof, convert into an Assumed Option, with the number of Fifth Third shares underlying such award and per share exercise price adjusted based on the exchange 
 ratio, and otherwise subject to the same terms and conditions as applied to the corresponding Comerica Stock Option in effect immediately prior to the effective time;                                                                                    |

| • |     | Comerica RSU Awards: each outstanding Comerica RSU Award that is not a Comerica Director RSU Award,                                                                                                                                                      
 whether vested or unvested, shall, automatically and without any required action on the part of the holder thereof, convert into an Assumed RSU Award, with the number of Fifth Third 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 RSU Award in effect immediately prior to the effective time. Any accrued but unpaid dividend equivalents for Comerica RSU Awards will carry over to the  
 Assumed RSU Awards;                                                                                                                                                                                                                                      |
