 may request a copy of the Indenture from us as described under “Where You Can Find More Information.” We have summarized the material terms of the Indenture and the Notes below, but the summary does not purport to be complete and is subject to and qualified in its entirety by reference to the Indenture and the Notes. The following description of the terms of the Indenture and the Notes supplements and, to the extent inconsistent therewith, replaces and supersedes the description of the general terms and provisions of the subordinated debt securities in the accompanying prospectus.

You should read the Indenture and the Notes because they, and not this description, define your rights as holders of the Notes. For purposes of this section, references to “Webster,” “we,” “us” and “our” include only Webster and not any of its subsidiaries.

General

The Notes will be unsecured and
subordinated obligations of Webster and will be issued as a series of the debt securities under the Indenture in an initial aggregate principal amount of $350,000,000. The Notes are not guaranteed by the Bank or any of our other subsidiaries or
affiliates, or any other person. We may, from time to time, without notice to or the consent of the holders of the Notes, create and issue additional notes ranking equally with the Notes and with identical terms in all respects (or in all respects
except for the offering price, the payment of interest accruing prior to the issue date of such additional notes and the first payment of interest following the issue date of such additional notes), subject to the procedures of the DTC;
provided, that a separate CUSIP or other identifying number will be issued for any such additional notes unless such additional notes are fungible with the Notes for U.S. federal income tax purposes.

The Notes will mature on September 11, 2035 (the “Maturity Date”), unless previously redeemed or otherwise accelerated.
Payment of principal on the Notes may be accelerated only in the case of certain events of our bankruptcy or insolvency. See “—Defaults; Events of Default; Limited Rights of Acceleration.”

We may, at our option, redeem the Notes (i) in whole, but not in part, on September 11, 2030 and (ii) in whole or in part, at
any time or from time to time, on or after June 11, 2035, subject to obtaining the prior approval of the Federal Reserve (or any successor
