Gentlemen and Ladies:

                  This  opinion is being  delivered  to you in  accordance  with
Section 7.1(f) of the Agreement and Plan of Merger (the  "Agreement"),  dated as
of December 1, 1999,  as amended on December  21, 1999,  by and between  Webster
Financial  Corporation  ("Webster"),  a Delaware corporation and MECH Financial,
Inc. ("MECH"), a Delaware corporation.  Pursuant to the Agreement,  MECH will be
merged with and into Webster (the  "Merger").  The  Agreement  also provides for
Mechanics  Savings Bank ("MS Bank"),  a Connecticut  chartered  savings bank and
wholly owned  subsidiary of MECH, to merge with and into Webster Bank  ("Webster
Bank"),  a federally  chartered  savings  bank and wholly  owned  subsidiary  of
Webster (the "Bank Merger").

                  In connection  with the  preparation of this opinion,  we have
examined and with your consent  relied upon the following  documents  (including
all exhibits and schedules  thereto):  (1) the Agreement;  (2) the  Registration
Statement on Form S-4 of Webster  Bancorp  (File No.  333-33228)  filed with the
Securities  and Exchange  Commission  ("SEC") on March 24, 2000,  as amended and
declared effective by the SEC on May ____, 2000 (the  "Registration  Statement")
and  the  Proxy   Statement/Prospectus   included   as  a  part   thereof;   (3)
representations  and certifications  made to us by Webster;  (4) representations
and  certifications  made to us by MECH;  and (5)  such  other  instruments  and
documents  related to the formation,  organization  and operation of Webster and
MECH  or to the  consummation  of  the  Merger  and  the  Bank  Merger  and  the
transactions contemplated thereby as we have deemed necessary or appropriate.

                  All  capitalized  terms used herein and not otherwise  defined
shall  have  the  same  meaning  as they  have  in the  Agreement.  All  section
references,  unless  otherwise  indicated,  are to the Internal  Revenue Code of
1986, as amended (the "Code").

                            The Proposed Transaction

                  Based solely upon our review of the documents set forth above,
and upon  such  information  as  Webster  and MECH  have  provided  to us and in
reliance upon such documents and  information,  we understand  that the proposed
transaction and the relevant facts with respect thereto are as follows:




                  Webster is the holding  company of Webster Bank.  Both Webster
and Webster  Bank are  headquartered  in  Waterbury,  Connecticut.  Webster Bank
offers full service business and retail banking services throughout Connecticut.

                  MECH  is  the  holding   company  of  MS  Bank.   MS  Bank  is
headquartered  in the  Hartford,  Connecticut.  MS Bank  conducts  business from
branch locations throughout the greater Hartford area. Historically, MS Bank has
been engaged in the business of attracting  deposits from the general public and
earning income on those funds through various lending and investment activities.

                  It is proposed  that pursuant to the Agreement and the General
Corporation Law of the State of Delaware, MECH will merge with and into Webster.
As a result of the Merger,  MECH's  corporate  existence  will cease and Webster
will be the Surviving Corporation.  As the Surviving  Corporation,  Webster will
succeed  to all  of the  assets  and  liabilities  of  MECH.  Immediately  after
consummation of the Merger, MS Bank will merge with and into Webster Bank in the
Bank Merger, with Webster Bank as the Surviving Bank.

                  The  purpose of the  Merger  and the Bank  Merger is to enable
Webster to acquire  the assets and  business  of MECH.  After the Merger and the
Bank Merger,  it is expected that some of MS Banks' branch banking  offices will
remain open and will be operated as banking  offices of Webster Bank. The Merger
and the Bank Merger will result in an expansion of Webster Bank's primary market
area to  include  MS Bank's  banking  offices  in  Connecticut.  The  assets and
business of MS Bank's banking offices will broaden Webster's existing operations
in Hartford County,  where Webster Bank currently has banking  offices.  Webster
expects to achieve reductions in the current operating expenses of MECH upon the
consolidation of MS Bank's operations into Webster Bank.

                  By virtue  of the  Merger,  each  share of MECH  Common  Stock
issued and outstanding prior to the Effective Time (other than certain shares to
be canceled) will be converted into and  exchangeable for 1.52 shares of Webster
Common Stock.  Certificates for fractions of shares of Webster Common Stock will
not be issued.  In lieu of a fraction of a share of Webster  Common Stock,  each
holder of MECH  Common  Stock  otherwise  entitled  to a fraction  of a share of
Webster  Common Stock will be entitled to receive an amount of cash equal to (i)
the  fraction of a share of the Webster  Common Stock to which such holder would
otherwise be entitled, multiplied by (ii) the actual market value of the Webster
Common Stock, which will be deemed to be the average of the daily closing prices
per share for Webster  Common Stock for the twenty  consecutive  trading days on
which shares of Webster  Common  Stock are  actually  traded (as reported on the
Nasdaq Stock Market  National  Market  System)  ending on the third  trading day
preceding the Closing Date.  Under Section  33-856 of the  Connecticut  Business
Corporation Act, MECH shareholders are entitled to dissent from the Merger.

                  At the Effective Time, each option granted by MECH to purchase
shares of MECH Common Stock which is  outstanding  and  unexercised  immediately
prior thereto will be converted  automatically into an option to purchase shares
of Webster  Common Stock,  with  adjustment in the number of shares and exercise
price to reflect the Exchange Ratio.

                         Assumptions and Representations

                  In connection with rendering this opinion,  we have assumed or
obtained  representations (and, with your consent, are relying thereon,  without
any independent  investigation  or review thereof,  although we are not aware of
any material facts or circumstances contrary to or inconsistent therewith) that:

                  1. All information  contained in each of the documents we have
examined and relied upon in connection  with the  preparation of this opinion is
accurate and  completely  describes all material  facts relevant to our opinion,
all copies are accurate  and all  signatures  are genuine.  We have also assumed
that  there  has been  (or  will be by the  Effective  Time of the



Merger) due  execution  and delivery of all  documents  where due  execution and
delivery are prerequisites to the effectiveness thereof.

                  2.  The  Merger  will  be  consummated   in  accordance   with
applicable  state law and will qualify as a statutory  merger  under  applicable
state law.

                  3.  All  representations  made to us are  true,  correct,  and
complete.  Any  representation  or statement  made "to the best of knowledge" or
similarly qualified is correct without such qualification.

                  4.  The Merger  will be  consummated  in  accordance  with the
Agreement  and  as  described  in  the  Proxy  Statement/Prospectus   (including
satisfaction  of all covenants and conditions to the  obligations of the parties
without amendment or waiver thereof); both Webster and MECH will comply with all
reporting obligations with respect to the Merger required under the Code and the
Treasury Regulations  thereunder;  and the Agreement and all other documents and
instruments referred to therein or in the Proxy  Statement/Prospectus  are valid
and binding in accordance with their terms.

                    Opinion - Federal Income Tax Consequences

                  Based upon and subject to the assumptions  and  qualifications
set forth  herein,  it is our opinion  that for Federal  income tax purposes the
Merger will qualify as a reorganization  within the meaning of Section 368(a) of
the Code.

                  In addition to the assumptions  set forth above,  this opinion
is subject to the exceptions, limitations and qualifications set forth below:

                  1. This opinion represents and is based upon our best judgment
regarding  the  application  of  relevant  current  provisions  of the  Code and
interpretations  of the  foregoing  as expressed  in existing  court  decisions,
administrative  determinations  (including  the practices and  procedures of the
Internal  Revenue Service (the "IRS") in issuing  private letter rulings,  which
are not binding on the IRS except with  respect to the  taxpayer  that  receives
such a ruling) and published  rulings and  procedures all as of the date hereof.
An opinion of counsel merely represents  counsel's best judgment with respect to
the probable  outcome on the merits and is not binding on the IRS or the courts.
There can be no assurance  that  positions  contrary to our opinions will not be
taken by the IRS, or that a court considering the issues would not hold contrary
to such opinions.  Neither  Webster nor MECH has requested a ruling from the IRS
(and no ruling will be sought) as to any of the federal income tax  consequences
addressed in this  opinion.  Furthermore,  no assurance can be given that future
legislative,  judicial or  administrative  changes,  on either a prospective  or
retroactive  basis,  would not  adversely  affect the  accuracy  of the  opinion
expressed herein. Nevertheless,  we undertake no responsibility to advise you of
any new developments in the law or in the application or  interpretation  of the
federal income tax laws.

                  2. This letter  addresses  only the  specific  tax opinion set
forth above.  This letter does not address the Bank Merger or any other federal,
state,  local or foreign tax consequences that may result from the Merger or any
other transaction  (including any transaction  undertaken in connection with the
Merger).

                  3. We express no opinion  regarding,  among other things,  the
tax  consequences  of the Merger  (including  the  opinion  set forth  above) as
applied to specific  shareholders  of MECH or that may be relevant to particular
classes  of  MECH  shareholders,  such  as  dealers  in  securities,   corporate
shareholders  subject to the  alternative  minimum  tax,  foreign  persons,  and
holders  of  shares  acquired  upon  exercise  of  stock  options  or  in  other
compensatory transactions.  In addition, we express no opinion regarding the tax
consequences  to a holder of an option to purchase  shares of MECH Common  Stock
who  receives an option to purchase  shares of Webster  Common Stock in exchange
therefor pursuant to the Merger.



                  4. Our opinion set forth herein is based upon the  description
of the  contemplated  transactions  as set forth  above in the  section  of this
letter captioned "The Proposed  Transaction," and in the Agreement and the Proxy
Statement/Prospectus  (the "Transactions").  If the actual facts relating to any
aspect of the Transactions differ from this description in any material respect,
our  opinion  may  become  inapplicable.  No  opinion  is  expressed  as to  any
transaction  other  than  the  Transactions  or to any  transaction  whatsoever,
including the Merger, if the Transactions are not consummated in accordance with
the  terms of the  Agreement  and  without  waiver  or  breach  of any  material
provision thereof or if all of the representations,  warranties,  statements and
assumptions  upon  which we relied  are not true and  accurate  at all  relevant
times.  In the event any one of the statements,  representations,  warranties or
assumptions  upon which we have relied to issue this opinion is  incorrect,  our
opinion might be adversely affected and may not be relied upon.

                  This opinion is provided to Webster and MECH only, and without
our prior consent, may not be relied upon, used, circulated, quoted or otherwise
referred to in any manner by any person, firm,  governmental authority or entity
whatsoever  other  than  reliance   thereon  by  Webster,   MECH  and  the  MECH
shareholders.  Notwithstanding the prior sentence,  we hereby consent to the use
of the opinion letter as an exhibit to the Registration Statement and to the use
of our name in the  Registration  Statement.  In giving the  consent,  we do not
thereby admit that we are an "expert"  within the meaning of the  Securities Act
of 1933, as amended.

                                               Sincerely yours,



                                               HOGAN & HARTSON L.L.P.
