 WEBSTER FINANCIAL CORPORATION, a corporation duly organized and existing under the laws of the State of Delaware (herein
called the “Company,” which term includes any successor Person under the Indenture referred to on the reverse hereof), for value received, hereby promises to pay to Cede & Co., or registered assignee, the principal sum of
                 United States dollars (U.S.$                ) on
March 25, 2029 and to pay interest thereon, from and including March 25, 2019, or from and including the most recent Interest Payment Date (as defined below) to which interest has been paid or duly provided for, semiannually in arrears on

America as at the time of payment shall be legal tender for the payment of public and private debts, by dollar check drawn on, or transfer to, a dollar account. Payments of interest on this Note may be made in like coin or currency by check, drawn
on a dollar account, mailed to the address of the Person entitled thereto as such address shall appear in the Security Register, or, upon written application by the Holder to the Paying Agent setting forth wire instructions not later than the

redeemed are registered as a Global Security, the Depository shall determine, in accordance with its procedures, the principal amount of the Notes to be redeemed held by each of its participants that holds a position in such Notes. Interest shall

such other Note.

such proceeding and no direction inconsistent with such written request has been given to the Trustee during such 60-day period by the Holders of a majority in principal amount of the Notes that are
Outstanding. The foregoing shall not apply to any suit instituted by any Holder of this Note for the enforcement of any payment of principal of, or premium, if any, or interest on this Note on or after the respective due dates expressed or provided
for herein. 
 No reference herein to the Indenture and no provision of this Note or of the Indenture shall alter or impair the obligation
of the Company, which is absolute and unconditional, to pay the principal of and premium, if any, and interest on this Note at the times, places and rate, and in the coin or currency, herein prescribed.
