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),
