The CIC Agreement for Mr. Farmer provides for a modified make-whole payment if any change-in-controlpayments or benefits become subject to the excise tax under Section 4999 of the Code, but only if the total change-in-controlpayments and benefits exceed 110% of the threshold at which Section 4999 of the Code becomes applicable to him. The CIC Agreements for all other executive officers do not include a make-whole provision. Instead, these agreements contain a “net-best”cutback provision, under which the change-in-controlpayments and benefits will be reduced to the maximum amount that does not trigger the excise tax under Section 4999 of the Code, unless the executive officer would retain a greater after-taxvalue by receiving the full payments and benefits and paying the excise tax. Concurrently with the execution of the merger agreement, Fifth Third entered into a letter agreement with Mr. Farmer (as described in more detail in “ CEO Letter Agreement with Fifth Third” below), which generally supersedes Mr. Farmer’s CIC Agreement (except for the modified make-whole payment). See the section entitled “— Quantification of Potential Payments and Benefits to Comerica’s Named Executive Officers in Connection with the Mergers” below for the estimated amounts that each of Comerica’s named executive officers would receive under the CIC Agreements upon a qualifying termination of employment following the effective time. Based on the assumptions described above under “ —Certain Assumptions,” the estimated aggregate value of the change-in-controlseverance benefits that the thirteen executive officers who are not named executive officers would receive under the CIC Agreements upon a qualifying termination of employment following the effective time is $48,352,230 (assuming no reduction in payments or benefits for purposes of the excise tax under Section 4999 of the Code).
