Ladies and Gentlemen:

     We  are  acting  as  counsel  to   Webster   Financial   Corporation   (the
"Corporation"),  a Delaware corporation,  in connection with its registration on
Form S-4, as amended (the  "Registration  Statement")  filed with the Securities
and  Exchange  Commission  relating  to the  proposed  public  offering of up to
1,337,618  shares of Common Stock, par value $.01 per share, all of which shares
(the  "Shares") are to be issued by the  Corporation  of Shelton  Bancorp,  Inc.
("Shelton")  in  accordance  with the terms of the  Agreement and Plan of Merger
dated June 20, 1995,  as amended  (the  "Agreement"),  between the  Corporation,
Webster  Acquisition Corp. and Shelton.  This opinion letter is furnished to you
at your request to enable you to fulfill the  requirements  of Item 601(b)(5) of
Regulation S-K, 17 C.F.R. ss. 229.601(b)(5), in connection with the Registration
Statement.

     For  purposes  of this  opinion  letter,  we have  examined  copies  of the
following documents:

     1. An executed copy of the Registration Statement;

     2. An executed copy of the Agreement;

     3. The Restated  Certificate  of  Incorporation  of the  Corporation,  with
amendments thereto, as certified by the Secretary of the Corporation on the date
hereof as then being complete, accurate and in effect;

     4. The Bylaws of the Corporation, as amended, as certified by the Secretary
of the  Corporation on the date hereof as then being  complete,  accurate and in
effect; and

     5.  Resolutions  of the Board of  Directors of the  Corporation  adopted at
meetings  held on June 19, 1995 and July 24, 1995, as certified by the Secretary
of the  Corporation on the date hereof as then being  complete,  accurate and in
effect,  relating  to,  among  other  things,  the  issuance  of the  Shares and
arrangements in connection therewith.

     In  our  examination  of the  aforesaid  documents,  we  have  assumed  the
genuineness  of all  signatures,  the legal  capacity  of natural  persons,  the
authenticity,  accuracy and  completeness of all documents  submitted to us, and
the conformity with the original  documents of all documents  submitted to us as
certified, telecopied, photostatic, or reproduced copies. This opinion letter is
given, and all statements herein are made, in the context of the foregoing.

     This  opinion  letter is based as to matters  of law solely on the  General
Corporation Law of the State of Delaware. We express no opinion herein as to any
other laws,  statutes,  regulations,  or ordinances.  Based upon, subject to and
limited by the foregoing, we are of the opinion that following (i) effectiveness
of the Registration Statement, (ii) issuance of the Shares pursuant to the terms
of the Agreement,  and (iii) receipt by the Corporation of the consideration for
the Shares specified in the Agreement and resolutions of the Board of Directors,
the  Shares  will be validly  issued,  fully  paid and  nonassessable  under the
General Corporation Law of the State of Delaware.

     We assume no  obligation  to advise  you of any  changes  in the  foregoing
subsequent to the delivery of this opinion letter.  This opinion letter has been
prepared solely for your use in connection  with the filing of the  Registration
Statement on the date of this  opinion  letter and should not be quoted in whole
or in part or  otherwise  be  referred  to, nor filed with or  furnished  to any
governmental agency or other person or entity, without the prior written consent
of this firm.

     We hereby  consent to the filing of this opinion letter as Exhibit 5 to the
Registration  Statement  and to the  references  to this firm under the captions
"The Merger - Certain  Federal Income Tax  Consequences"  and "Legal Matters" in
the joint proxy  statement/prospectus  constituting  a part of the  Registration
Statement.  In giving  this  consent,  we do not  thereby  admit  that we are an
"expert" within the meaning of the Securities Act of 1933, as amended.

                                                       Very truly yours,


                                                       HOGAN & HARTSON L.L.P.
