 the Trustee’s receipt thereof shall not constitute actual or constructive notice of any information contained therein or
determinable from information contained therein, including our compliance with covenants under the Indenture and the Notes, as to which the Trustee is entitled to rely exclusively on officers’ certificates.

No recourse will be available for the payment of principal of, or interest on, any Note, for any claim based thereon, or otherwise in respect
thereof, against any shareholder, employee, officer or director, as such, past, present or future, of Webster or any successor entity. Neither the Indenture nor the Notes contain any covenants or restrictions restricting the incurrence of debt,
deposits or other liabilities by us or by our subsidiaries. The Indenture and the Notes contain no financial covenants and do not restrict us from paying dividends, selling assets, making investments or issuing or repurchasing other securities, and
do not contain any provision that would provide protection to the holders of the Notes against a sudden and dramatic decline in credit quality resulting from a merger, takeover, recapitalization or similar restructuring or any other event involving
us or our subsidiaries that may adversely affect our credit quality.

The Notes are not savings accounts, deposits or other obligations of
the Bank or any of our non-bank subsidiaries and are not insured or guaranteed by the FDIC or any other governmental agency or public or private insurer. The Notes are solely obligations of Webster and are
neither obligations of, nor guaranteed by, any of our subsidiaries.

We do not intend to apply for the listing of the Notes on any
securities exchange or the quotation of the Notes on any automated quotation system.
