                                                       _____________ ___, 1996




TO THE SHAREHOLDERS OF
DS BANCOR, INC.:


     You are cordially  invited to attend a special meeting of shareholders (the
"DS  Bancor  Meeting")  of  DS  Bancor,   Inc.  ("DS  Bancor")  to  be  held  on
_____________ __, 1997,  at ___ a.m. at  ______________________________________,
Connecticut.

     As described in the enclosed  Joint Proxy  Statement/Prospectus,  at the DS
Bancor  Meeting you will be asked to approve the  Agreement  and Plan of Merger,
dated as of October 7, 1996, among Webster  Financial  Corporation  ("Webster"),
Webster Acquisition Corp. ("Merger Sub") and DS Bancor (the "Merger Agreement"),
and the  merger  provided  for  therein,  pursuant  to which DS Bancor  would be
acquired by Webster.  The Merger  Agreement  provides for the  acquisition of DS
Bancor to occur by merging  Merger  Sub, a  wholly-owned  subsidiary  of Webster
formed for such purpose, into DS Bancor (the  "Merger").  Upon the Merger,  each
outstanding  share of DS Bancor common stock ("DS Bancor Common  Stock") will be
converted  into a certain  number of shares of Webster  common  stock  ("Webster
Common  Stock"),  plus  cash to be paid in  lieu  of  fractional  shares.  It is
intended that such  conversion  will qualify as a tax-free  exchange for federal
income tax purposes.

     Each share of DS Bancor  Common  Stock will entitle its holder to one vote.
Consummation  of  Webster's  acquisition  of DS Bancor  is  subject  to  certain
conditions, including approval of the Merger Agreement by at least two-thirds of
the outstanding  shares of DS Bancor Common Stock entitled to be voted at the DS
Bancor Meeting and the receipt of certain regulatory approvals.  Consummation of
the transaction is also subject to the approval by the holders of Webster Common
Stock of the issuance of additional shares of Webster Common Stock in connection
with the  transactions  contemplated  by the  Merger  Agreement.  Approval  of a
proposed  amendment to  Webster's  restated  certificate  of  incorporation,  as
amended, which also is being sought by Webster, is not a condition to the Merger
Agreement.

         Alex. Brown & Sons Incorporated ("Alex.  Brown"), DS Bancor's financial
advisor in connection  with the Merger,  has delivered its written opinion to DS
Bancor's Board of Directors  that, as of the date of the Merger  Agreement,  the
consideration  to be received by the  holders of DS Bancor  Common  Stock in the
Merger was fair to such  holders  from a  financial  point of view.  The written
opinion of Alex.  Brown is reproduced in full as Appendix A to the  accompanying
Joint Proxy Statement/Prospectus.


         YOUR BOARD OF DIRECTORS  UNANIMOUSLY  APPROVED THE MERGER AGREEMENT AND
THE MERGER PROVIDED FOR THEREIN AND RECOMMENDS  THAT YOU VOTE "FOR" APPROVAL OF
THE MERGER AGREEMENT AND THE MERGER PROVIDED FOR THEREIN.




     THE REQUIRED VOTE OF THE DS BANCOR  SHAREHOLDERS WITH RESPECT TO THE MERGER
AGREEMENT  IS BASED  UPON THE TOTAL  NUMBER OF  OUTSTANDING  SHARES OF DS BANCOR
COMMON  STOCK  AND NOT UPON THE  NUMBER  OF SHARES  WHICH  ARE  ACTUALLY  VOTED.
ACCORDINGLY,  THE  FAILURE TO SUBMIT A PROXY CARD OR TO VOTE IN PERSON AT THE DS
BANCOR MEETING OR THE ABSTENTION FROM VOTING BY A SHAREHOLDER WILL HAVE THE SAME
EFFECT AS A VOTE  "AGAINST"  THE MERGER  AGREEMENT  AND THE MERGER  PROVIDED FOR
THEREIN.

         You are urged to carefully  read the Joint Proxy  Statement/Prospectus,
which  provides you with a description of the Webster Common Stock and the terms
of the Merger.  A copy of the Merger  Agreement  (including each of the exhibits
thereto)  and the other  documents  described  in the  accompanying  Joint Proxy
Statement/Prospectus  will be  provided  without  charge  upon  oral or  written
request to Lee A. Gagnon, Executive Vice President,  Chief Operating Officer and
Secretary  of  Webster   Financial   Corporation,   Webster  Plaza,   Waterbury,
Connecticut  06702,  telephone  (203)  578-2217.  IT IS VERY IMPORTANT THAT YOUR
SHARES BE  REPRESENTED  AT THE DS  BANCOR  MEETING.  WHETHER  OR NOT YOU PLAN TO
ATTEND THE DS BANCOR MEETING,  YOU ARE REQUESTED TO COMPLETE,  DATE AND SIGN THE
PROXY  CARD AND  RETURN IT AS SOON AS  POSSIBLE  IN THE  ENCLOSED  POSTAGE  PAID
ENVELOPE.  FAILURE TO RETURN A PROPERLY EXECUTED PROXY CARD OR TO VOTE AT THE DS
BANCOR MEETING WILL HAVE THE SAME EFFECT AS A VOTE AGAINST THE MERGER AGREEMENT.



                                    Sincerely,



                                    HARRY P. DIADAMO, JR.

Corporation ("Webster").  This Joint Proxy  Statement/Prospectus  relates to the
special  meeting of  shareholders  of DS Bancor (the "DS Bancor  Meeting") to be
held     on      ____________      ___,     1997,     at     ___     a.m.     at
______________________________________________,  Connecticut, and to the special
meeting  of  shareholders  of  Webster  (the  "Webster  Meeting")  to be held on
________________        ___,       1997,       at       ____       a.m.       at
___________________________________________,    Connecticut,    and    to    any
adjournments or  postponements of the DS Bancor Meeting and the Webster Meeting.
This Joint Proxy  Statement/Prospectus  is first being mailed to shareholders of
DS Bancor and to shareholders of Webster on or around ____________ ___, 1996.

     At the DS  Bancor  Meeting,  the  principal  item  of  business  will be to
consider and vote upon the approval  and adoption of the  Agreement  and Plan of
Merger,  dated as of October 7, 1996, among Webster,  Webster  Acquisition Corp.
("Merger Sub"),  and DS Bancor (the "Merger  Agreement") and the merger provided
for therein.  At the Webster  Meeting,  the principal items of business will be:
(i) to  consider  and vote upon a proposal  to  approve  the  issuance  of up to
4,681,658  shares of Webster  common stock,  par value $.01 per share  ("Webster
Common  Stock")  in  connection  with the  acquisition  of DS Bancor by  Webster
pursuant to the Merger Agreement,  and (ii)_to consider and vote upon a proposal
to approve an amendment to Webster's restated  certificate of incorporation,  as
amended   ("Restated   Certificate  of  Incorporation")  to  increase  Webster's
authorized  capital  stock by  increasing  the  number of  authorized  shares of
Webster  Common Stock from  14,000,000 to  30,000,000.  The holders of Webster's
Series B 7 1/2% Cumulative  Convertible  Preferred Stock ("Series B  Stock") are
not entitled to vote at the Webster Meeting.  Approval of the proposed amendment
to Webster's  Restated  Certificate of  Incorporation  is not a condition to the
Merger Agreement.

         The Merger  Agreement  provides for DS Bancor to be acquired by Webster
through a merger of Merger Sub, a wholly-owned  subsidiary of Webster formed for
such purpose, into DS Bancor (the "Merger").  As part of the Merger, each issued
and outstanding  share of DS Bancor common stock, par value $1.00 per share ("DS
Bancor Common  Stock"),  will be converted into a specified  number of shares of
Webster  Common  Stock  (the  "Exchange  Ratio").  Cash  will be paid in lieu of
fractional  shares.  The Exchange Ratio will be determined by dividing $43.00 by
the Base Period Trading Price (defined below),  computed to five decimal places.
The Exchange Ratio is subject to adjustment such that if the Base Period Trading
Price is greater  than $38.50,  the  Exchange  Ratio shall be 1.11688 and if the
Base Period  Trading  Price is less than  $31.50,  the  Exchange  Ratio shall be
1.36508.  Furthermore, if the Base Period Trading Price is less than $28.00, the
Merger  Agreement may be terminated by DS Bancor unless  Webster elects that the
Exchange Ratio shall be equal to the number  resulting  from dividing  $38.22 by
the Base Period Trading Price which may require Webster to register


                                      -1-



additional shares with the Securities and Exchange  Commission  ("SEC") and seek
further shareholder approval.

     The "Base Period  Trading  Price" will be the average of the daily  closing
prices per share for Webster Common Stock for the 15 consecutive trading days on
which shares of Webster  Common  Stock are  actually  traded (as reported on The
Nasdaq  National  Market)  ending on the day  preceding  the receipt of the last
required  federal bank  regulatory  approval.  Based on the average of the daily
closing prices per share for Webster Common Stock for the 15 consecutive trading
days on which  shares of Webster  Common  Stock were  actually  traded  prior to
____________  ___, 1996 (the most recent  practicable date prior to the printing
of this Joint Proxy  Statement/Prospectus)  of  $____*____,  the Exchange  Ratio
would be  _________*_________.  Because the market price of Webster Common Stock
is  subject  to  fluctuation,  the  Exchange  Ratio for the  number of shares of
Webster  Common Stock that holders of DS Bancor Common Stock will receive in the
Merger may materially increase or decrease prior to the Merger. No assurance can
be  given as to the  market  price of  Webster  Common  Stock at the time of the
Merger.  See  "MARKET  PRICES  AND  DIVIDENDS."  In  connection  with the Merger
Agreement, DS Bancor has granted Webster an irrevocable option (the "Option") to
purchase  up to  564,296  newly  issued  shares of DS Bancor  Common  Stock at a
purchase price of $36.50 per share (which price is subject to  adjustment)  upon
the occurrence of certain events.  The Merger is subject to various  conditions,
including   approvals  of   applicable   federal  and   Connecticut   regulatory
authorities. DS Bancor and Webster expect that the Merger will be consummated in
the first  quarter  of 1997,  or as soon as  possible  after the  receipt of all
regulatory  and  shareholder  approvals  and the  expiration  of all  regulatory
waiting  periods.  If the Merger is not consummated by June 30, 1997, the Merger
Agreement will be terminated unless DS Bancor and Webster mutually consent to an
extension.  For a more detailed  description  of the Merger and the Option,  see
"The Merger."

     This Joint Proxy  Statement/Prospectus  also  constitutes  a prospectus  of
Webster  with  respect to the up to  4,681,658  shares of Webster  Common  Stock
subject to issuance in connection  with the  acquisition of DS Bancor by Webster
pursuant to the Merger Agreement.

                                 MERGER SUMMARY

     The following is a brief summary of certain information contained elsewhere

complete  description  and is qualified in its entirety by reference to the more
detailed    information    contained    elsewhere    in   this    Joint    Proxy

Webster  Bank's  goal is to provide  banking  services  that are fairly  priced,
reliable and convenient.

     At  September 30,   1996,   Webster  had  total   consolidated   assets  of

corporate  existence  of Merger Sub will  terminate  upon the  Merger.  See "THE
MERGER -- The Parties."

     DS Bancor.  DS Bancor,  a Delaware  corporation,  is the holding company of
Derby Savings Bank ("Derby"), a Connecticut-chartered savings bank headquartered
in Derby,  Connecticut.  Deposits at Derby are FDIC insured.  Through Derby,  DS

     At  September 30,   1996,  DS  Bancor  had  total  consolidated  assets  of
$1.3 billion,  total  deposits  of  $1.0 billion,  and  shareholders'  equity of
$86.5 million, or 6.87% of total assets. DS Bancor Common Stock is quoted on The
Nasdaq  National  Market  under the symbol  "DSBC".  The  address of DS Bancor's
principal  executive  offices is DS Bancor,  Inc., 33 Elizabeth  Street,  Derby,
Connecticut 06418,  and its telephone number is (203) 736-1000.  See "THE MERGER
- -- The Parties." 

THE MERGER

     General.  The Merger Agreement provides for the acquisition of DS Bancor by
Webster  through the merger of Merger Sub into DS Bancor,  with DS Bancor as the
surviving  corporation  (the  "Surviving  Corporation").  Immediately  after the
consummation of the Merger,  (i) Webster intends that the Surviving  Corporation
will be merged  Shelton into Webster,  with Webster being the surviving  holding
company, and (ii) Derby will be merged into Webster Bank (the "Bank Merger"),

                                      -7-


with Webster  Bank as the  surviving  federal  savings  bank.  Webster Bank will
remain  headquartered  in Waterbury,  Connecticut  as an FDIC insured  federally
chartered savings bank.

     At the Effective  Time (as defined below) of the Merger,  each  outstanding
share of DS Bancor  Common Stock,  (except for shares held as treasury  stock or
held, directly or indirectly, by Webster, DS Bancor or any of their subsidiaries
(other than shares held in a fiduciary  capacity  ("Trust Account Shares") or in
respect  of  a  debt  previously  contracted  ("DPC  Shares"),  which  shall  be
canceled),  will be converted  into a certain number of shares of Webster Common
Stock,  plus cash to be paid in lieu of  fractional  shares.  See "The Merger --
Exchange  Ratio." See "The MERGER -- Exchange Ratio." The Merger will not change
the outstanding Webster Common Stock held by the Webster shareholders.

     DS Bancor and Webster  expect that the Merger  will be  consummated  in the
first  quarter  of  1997,  or as soon  as  possible  after  the  receipt  of all
regulatory  and  shareholder  approvals,  and the  expiration of all  regulatory
waiting  periods.  If the Merger is not consummated by June 30, 1997, the Merger
Agreement will be terminated unless DS Bancor and Webster mutually consent to an
extension. See "THE MERGER -- Structure."

     Exchange Ratio. The Merger  Agreement  provides that at the Effective Time,
each issued and  outstanding  share of DS Bancor Common Stock (other than shares
held, directly or indirectly, by DS Bancor, Webster or any of their subsidiaries
(other than Trust Account  Shares or DPC Shares),  which shall be canceled) will
be  converted  automatically  at the Exchange  Ratio into a specified  number of
shares of  Webster  Common  Stock.  The  Exchange  Ratio will be  determined  by
dividing  $43.00 by the Base  Period  Trading  Price  computed  to five  decimal
places.  Cash will be paid in lieu of fractional  shares.  The Exchange Ratio is
subject to adjustment such that if the Base Period Trading Price is greater than
$38.50, the Exchange Ratio shall be 1.11688 and if the Base Period Trading Price
is less than $31.50,  the Exchange Ratio shall be 1.36508.  Furthermore,  if the
Base Period  Trading  Price is less than  $28.00,  the Merger  Agreement  may be
terminated by DS Bancor unless  Webster  elects that the Exchange Ratio shall be
equal to the number  resulting  from dividing  $38.22 by the Base Period Trading
Price which may require Webster to register  additional  shares with the SEC and
seek further shareholder approval.

     Based on the  $__*__  average  of the daily  closing  prices  per share for
Webster  Common  Stock for the 15  consecutive  trading  days on which shares of
Webster Common Stock were actually traded prior to  ____________  ___, 1996 (the
most   recent   practicable   date  prior  to  the  date  of  this  Joint  Proxy
Statement/Prospectus),  the Exchange Ratio would be ___*___.  Because the market
price of Webster Common Stock is subject to fluctuation,  the Exchange Ratio for
shares of Webster  Common  Stock that  holders  of DS Bancor  Common  Stock will
receive in the Merger may  materially  increase or decrease prior to the Merger.
No assurance  can be given as to the  Exchange  Ratio at the time of the Merger.
See "MARKET PRICES AND DIVIDENDS." Such variance would not alter Webster's or DS
Bancor's obligation to consummate the Merger, except as provided above. Based on
the ________  shares of DS Bancor Common Stock  outstanding on ___________  ___,
1996 and the Exchange  Ratio of __*__,  Webster would issue up to  ______*______
shares of Webster Common Stock to the DS Bancor shareholders in the Merger, plus
cash in lieu of  fractional  shares.  These  numbers do not  reflect  additional
shares of Webster  Common Stock to be issued in the event of the exercise  prior
to the Merger of the  _____*_____  existing  stock  options  held by  directors,
officers and employees of DS Bancor.

     DS Bancor  Meeting.  The DS Bancor Meeting will be held on  __________ ___,
1997 at ______a.m. at __________________________________,  Connecticut, at which
time the holders of record of DS Bancor Common Stock at the close of business on
_______________ __, 1996 (the "DS Bancor Record Date") will be asked to consider
and vote upon: (i) a proposal to approve and adopt the Merger  Agreement and the
Merger  provided for therein,  and  (ii) such  other  matters as may properly be
brought  before  the DS Bancor  Meeting  or any  adjournments  or  postponements
thereof.  The  affirmative  vote of the holders of two-thirds of the outstanding
shares of DS Bancor  Common Stock  entitled to vote at the DS Bancor  Meeting is
required to approve and adopt the Merger  Agreement and the Merger  provided for
therein.

     All of the  directors  of DS Bancor,  who  beneficially  owned as of the DS
Bancor  Record Date,  an aggregate of ___*___  shares of DS Bancor  Common Stock
(excluding all stock options) or approximately _*_% of the outstanding shares of
DS Bancor, have entered into a stockholder  agreement with Webster,  dated as of
October 7, 1996 (the "Stockholder  Agreement"), pursuant to which they have each
agreed,  among other  things,  to vote all shares of DS Bancor Common Stock with
respect to which  they have the right to vote in favor of the Merger  Agreement,
the Merger and the other  transactions  contemplated by the Merger Agreement and
against any third party merger proposal. The executive officers of DS Bancor and
Derby  also  entered  into the  Stockholder  Agreement  insofar as it relates to
transfer  restrictions and certain other matters. No separate  consideration was
paid to any of the  directors  or  executive  officers  for  entering  into  the
Stockholder  Agreement.  Webster  required  that the  Stockholder  Agreement  be
executed as a condition to Webster entering into the Merger  Agreement.  See "DS
BANCOR MEETING."

     The Board of Directors of DS Bancor  believes  that the terms of the Merger
Agreement  are  fair  to,  and in the  best  interests  of,  DS  Bancor  and its
shareholders.  The Board of  Directors  of DS Bancor  unanimously  approved  the
Merger Agreement and the Merger provided for therein and recommends that holders
of DS Bancor  Common  Stock  vote  "FOR"  approval  and  adoption  of the Merger
Agreement and the Merger  provided for therein.  For a discussion of the factors
considered by the Board of Directors in reaching its  decision,  see "THE MERGER
- --  Background of the Merger" and "--  Recommendation  of the DS Bancor Board of
Directors and Reasons for the Merger."

     Webster Meeting. The Webster Meeting will be held on _________ __, 1997, at
______a.m. at  ________________________,  Connecticut, at which time the holders
of   record   of   Webster   Common   Stock  at  the   close  of   business   on
___________________,  1996 (the "Webster Record Date") will be asked to consider
and vote upon: (i) a proposal to approve the issuance of up to 4,681,658  shares
of Webster  Common  Stock in  connection  with the  acquisition  of DS Bancor by
Webster  pursuant  to the Merger  Agreement,  (ii) the  amendment  of  Webster's
Restated  Certificate of Incorporation to increase Webster's  authorized capital
stock by increasing the number of authorized shares of Webster Common Stock from
14,000,000  to  30,000,000,  and  (iii) such  other  business as may properly be
brought before the Webster Meeting or any adjournments or postponements thereof.
The Merger is  conditioned  on the approval by the Webster  shareholders  of the
issuance of these shares of Webster  Common Stock,  which  approval  requires an
affirmative  vote of a majority  of the total  votes cast on the  proposal.  The
Board of Directors of Webster  believes  that the terms of the Merger  Agreement
are fair to, and in the best  interests  of Webster  and its  shareholders.  THE
BOARD OF DIRECTORS OF WEBSTER UNANIMOUSLY APPROVED THE ISSUANCE OF THE SHARES IN
CONNECTION  WITH THE MERGER  AGREEMENT  AND THE PROPOSED  AMENDMENT TO WEBSTER'S
RESTATED  CERTIFICATE  OF  INCORPORATION  TO INCREASE  THE NUMBER OF  AUTHORIZED
SHARES OF

WEBSTER  COMMON STOCK AND  RECOMMENDS  THAT THE HOLDERS OF WEBSTER  COMMON STOCK
VOTE "FOR" APPROVAL OF SUCH MATTERS.  For a discussion of the factors considered
by the  Board  of  Directors  in  reaching  its  decision,  see "THE  MERGER  --
Background  of the  Merger"  and "--  Recommendation  of the  Webster  Board  of
Directors and Reasons for the Issuance."

     Fairness Opinions. October 7, 1996, Alex. Brown & Sons Incorporated ("Alex.
Brown")  delivered its written opinion to the Board of Directors of DS Bancor to
the effect that, as of the date of its opinionsuch date, the terms of the Merger
Agreement,  including the Exchange  Ratio,  are fair,  from a financial point of
view,  to DS Bancor and its  shareholders.  The  receipt of this  opinion  was a
condition to DS Bancor's obligations under the Merger Agreement.  The opinion of
Alex.  Brown  describes  the  matters  considered  and the  scope of the  review
undertaken in rendering such opinion. Alex. Brown's opinion and presentations to
the DS  Bancor  Board,  together  with a review  by the DS  Bancor  Board of the
assumptions See "The Merger -- Alex. Brown Fairness  Opinionused by Alex. Brown,
were  among the  factors  considered  by the DS  Bancor  Board in  reaching  its
determination  to approve  the Merger  Agreement  and the  Merger  provided  for
therein.  On October 7,  1996, the date that Alex.  Brown delivered its opinion,
Webster Common Stock closed at $35.25 per share.  The Merger  Agreement does not
provide for an update by Alex. Brown of its opinion.  See "THE MERGER -- Opinion
of DS Bancor  Financial  Advisor." A copy of Alex.  Brown's opinion letter dated
October 7,   1996   is   attached   as   Appendix   A  to   this   Joint   Proxy
Statement/Prospectus  and  should  be  read  by DS  Bancor  shareholders  in its
entirety.

     The  Board  of  Directors  of  Webster  reviewed   financial  analyses  and
recommendations of Webster's management in considering the Merger.  Webster also
consulted  with  Merrill  Lynch & Co.  ("Merrill  Lynch") as to  certain  issues
concerning  the Merger,  including  the fairness of the terms of the Merger.  On
October 6, 1996, Merrill Lynch delivered its written fairness opinion to Webster
with  respect to the terms of the Merger.  See "THE MERGER -- Opinion of Webster
Financial  Advisor." A copy of Merrill Lynch's  opinion letter dated  October 6,
1996 is  attached at  Appendix B to this Joint  Proxy  Statement/Prospectus  and
should be read by Webster shareholders in its entirety.

     Regulatory  Approvals.  In order  for the  Merger  to be  consummated,  the
approvals of the Connecticut Commissioner and the OTS and the approval or waiver
of the Board of  Governors  of the  Federal  Reserve  System  ("Federal  Reserve
Board") are required.  Applications or waiver requests as to such approvals have
been  filed and are pending, or will be filed.   See "THE  MERGER --  Regulatory
Approvals."

     Accounting  Treatment.  The Merger is  intended to qualify as a "pooling of
interests" for accounting and financial reporting purposes.  Consummation of the
Merger  is  conditioned  upon the  Merger  so  qualifying.  See "THE  MERGER  --
Accounting Treatment."

     Federal  Income Tax  Consequences.  It is  intended  that the  Merger  will
qualify as a tax-free  reorganization for federal income tax purposes so that DS
Bancor  shareholders  generally should not recognize gain or loss as a result of
exchanging  their DS Bancor Common Stock for the Webster  Common Stock issued in
the Merger. See "THE MERGER -- Certain Federal Income Tax Consequences."

     No Appraisal  Rights.  Under Delaware law,  holders of the DS Bancor Common
Stock will not be entitled to any dissenters'  appraisal  rights with respect to
the Merger  since the DS Bancor  Common  Stock is traded on The Nasdaq  National
Market.  The  holders of Webster  Common  Stock  have no  dissenters'  appraisal
rights. See "THE MERGER -- No Appraisal Rights."

         Effective  Time.  The Merger will become  effective  on the filing of a
certificate  of merger with the  Secretary  of State of the State of Delaware in
accordance  with  applicable  law or on such  later date as the  certificate  of
merger may specify (the  "Effective  Time").  The  certificate of merger will be
filed  (i) on the  fifth day after  the last  required  regulatory  approval  is
received and all  applicable  waiting  periods have expired,  (ii) if elected by
Webster,  the last  business day of the month in which the date set forth in (i)
above  occurs,  or (iii) at such other time as the parties may agree.  DS Bancor
and Webster expect that the Merger will be consummated in the first quarter of

                                      -10-


1997, or as soon as possible after the receipt of all regulatory and shareholder
approvals and the expiration of all regulatory waiting periods. If the Merger is
not consummated by June 30, 1997, the Merger Agreement will be terminated unless
DS Bancor and Webster mutually consent to an extension.

     Termination.  The Merger  Agreement is subject to termination at the option
of Shelton or may be terminated  at any time prior to the Effective  Time by the
mutual consent of DS Bancor and Webster and by either of them individually under
certain specified  circumstances,  including if the Merger is not consummated by
June 30, 1997, or prior to such date upon the occurrence of certain events.  See
"THE MERGER -- Termination and Amendment of Merger Agreement."

     Exchange of DS Bancor Common Stock  Certificates.  Upon consummation of the
Merger (the  "Effective  Time")the  Effective Time, each holder of a certificate
representing DS Bancor Common Stock issued and outstanding  immediately prior to
the Merger will,  upon the  surrender  thereof (duly  endorsed,  if required) to
Webster's transfer agent, American Stock Transfer & Trust Company (the "Exchange
Agent"),  be entitled to receive a certificate  representing the number of whole
shares of Webster  Common Stock into which such DS Bancor Common Stock will have
been automatically converted as part of the Merger. The Exchange Agent will mail
a letter of transmittal with  instructions to all holders of record of DS Bancor
Common Stock  immediately  prior to the Effective  Time for use in  surrendering
their  certificates  for DS Bancor Common Stock in exchange for new certificates
representing Webster Common Stock.  CERTIFICATES SHOULD NOT BE SURRENDERED BY DS
BANCOR  SHAREHOLDERS  UNTIL  THE  LETTER OF  TRANSMITTAL  AND  INSTRUCTIONS  ARE
RECEIVED. See "THE MERGER -- Exchange Ratio."

     Option  Agreement.  As a condition of and inducement to Webster's  entering
into  the  Merger  Agreement,  Webster  and DS  Bancor  entered  into an  option
agreement,  dated as of October 7,  1996 (the "Option  Agreement"),  immediately
after their execution of the Merger Agreement. The Option Agreement may have the
effect of discouraging the making of alternative  acquisition-related proposals,
even if such proposal is for a higher price per share for DS Bancor Common Stock
than the  price  per  share  consideration  to be paid  pursuant  to the  Merger
Agreement.

     If the Option granted pursuant to the Option Agreement becomes exercisable,
Webster may  purchase at a price of $36.50 per share up to 564,296  newly issued
shares of DS Bancor Common Stock, or approximately 18.6% of the DS Bancor Common
Stock then outstanding.  The Option would become exercisable  primarily upon the
occurrence  of certain  events  that create the  potential  for a third party to
acquire DS Bancor.  To the  knowledge  of DS Bancor,  no event that would permit
exercise of the Option has occurred as of the date hereof. If the Option becomes
exercisable,  Webster or any permitted  transferee of Webster may, under certain
circumstances,  require DS Bancor to repurchase, for a formula price, the Option
(in lieu of its exercise) or any shares of DS Bancor Common Stock purchased upon
exercise of the Option. See "THE MERGER -- Option Agreement."

     INTERESTS OF CERTAIN PERSONS IN THE  MERGER-ARRANGEMENTS  WITH AND PAYMENTS
TO DS BANCOR DIRECTORS AND EXECUTIVE OFFICERS. The Merger Agreement provides for
two DS Bancor  directors  (selected  by the Board of Directors of Webster) to be
invited to serve as additional members of the Boards of Directors of Webster and
Webster Bank upon  consummation  of the Merger.  One  director  will serve until
Webster's  1998 annual  meeting and one will serve until  Webster's  1999 annual
meeting;  also, one of the two will be renominated when his or her term expires.
In  addition,  the  directors  of DS  Bancor  serving  immediately  prior to the
Effective  Time,  including  the two  directors  who will  serve on the Board of
Directors of Webster,  will be invited to serve on an advisory  board to Webster
Bank after the Bank Merger for a period of 24 months, with their compensation as
advisory directors to be based on a quarterly retainer of $4,750 and a quarterly
meeting attendance fee of $1,500. Such fees will not be payable to the DS Bancor
directors who also serve as Webster directors. See "THE

                                      -11-



MERGER -- Interests of Certain  Persons in the Merger --  Arrangements  with and
Payments to DS Bancor Directors and Executive Officers."

     Pursuant to existing  employment  and severance  agreements of DS Bancor or
Derby, as modified and limited by the Merger Agreement,  severance payments will
be made upon the  consummation of the Merger to Harry P. DiAdamo, Jr., Alfred T.
Santoro and Thomas H. Wells.  These  payments,  which are limited to the maximum
amount that can be paid without adverse tax  consequences  under Section 280G of
the Internal  Revenue Code of 1986,  as amended (the  "Code"),  will be based on
three times their respective average annual  compensation that was paid by Derby
and  includible  in their gross income for federal tax purposes for the calendar
years 1992 through 1996,  reduced by $1.00.  Such severance amounts will reflect
the amount of taxable compensation income reported by Messrs.  DiAdamo,  Santoro
and  Wells  from  employment  by  Derby  in  1996,   including   taxable  income
attributable to stock options exercised during 1996.  Messrs.  DiAdamo,  Santoro
and Wells  have  agreed to limit the  maximum  amount by which  their  severance
payments will be increased as a  consequence  of their 1996  nonqualified  stock
option exercises, and their disqualifying dispositions of stock acquired by 1996
incentive stock option exercises,  to an amount of additional severance based on
the market  price of DS Bancor  Common Stock being $40 per share at the times of
such exercises or dispositions, as applicable.

     Based on three times their respective  average annual  compensation paid by
Derby and  includible  in gross income for federal tax purposes for the calendar
years 1992 through  1996,  and assuming  that all  nonqualified  options held by
Messrs.  DiAdamo,  Santoro and Wells are exercised,  and that shares that can be
purchased  upon the  exercise of all  incentive  stock  options held by them are
disposed of in disqualifying dispositions,  in each case at a time when such per
share price is $40, the severance payable to Messrs. DiAdamo,  Santoro and Wells
upon  consummation  of the  Merger  would  be $2.7  million,  $1.7  million  and
$837,000, respectively.

     Also upon consummation of the Merger, Webster Bank has agreed to employ Mr.
Wells for a ten month  period as an  officer  to assist in the  transition  at a
salary of $10,000 per month and to retain him as a part-time  consultant for six
months thereafter at a salary of $7,500 per month. See " THE MERGER -- Interests
of Certain  Persons in the Merger - Arrangements  with and Payments to DS Bancor
Directors and Executive Officers."

     Webster has agreed to (i) indemnify the  directors,  officers and employees
of DS Bancor and Derby as to certain matters, and (ii) subject to the conditions
set forth in the Merger  Agreement,  use its best  efforts to cause the  persons
serving  as  officers  and  directors  of DS  Bancor  immediately  prior  to the
Effective Time to be covered by directors' and officers' liability insurance for
a period of at least two years. See "THE MERGER -- Indemnification."

COMPARISON OF SHAREHOLDER RIGHTS

     If the Merger is  consummated,  the holders of DS Bancor  Common Stock will
become holders of Webster Common Stock.  There are certain  differences  between
the rights of Webster shareholders and DS Bancor shareholders.  For a summary of
such  differences,  see  "DESCRIPTION OF WEBSTER CAPITAL STOCK AND COMPARISON OF
SHAREHOLDER RIGHTS."

     Both  Webster  Common  Stock and DS Bancor  Common  Stock are traded on The
Nasdaq  National  Market.  The symbol for Webster  Common  Stock is "WBST".  The

(a)  Determined by  multiplying  the  respective  closing  prices of the Webster
     Common Stock by the Exchange  Ratio  calculated  based on the average daily
     closing  prices per share of Webster  Common  Stock for the 15  consecutive
     trading days on which shares of Webster  Common Stock were actually  traded
     prior to  _______________  __, 1996 (the most recent practicable date prior
     to the date of this Joint Proxy Statements/Prospectus).  See "THE MERGER --

     effectiveness of Registration Statement.

     Shareholders  are advised to obtain current  market  quotations for Webster
Common Stock.  It is expected that the market price of Webster Common Stock will
fluctuate between the date of this Joint Proxy Statement/Prospectus and the date
on which the  Merger is  consummated.  Because  the  number of shares of Webster
Common  Stock to be  received  by DS Bancor  shareholders  in the  Merger is not
fixed,  the Exchange Ratio for the number of shares of Webster Common Stock that
the holders of DS Bancor Common Stock will receive in the Merger may increase or
decrease  prior to the Merger.  No assurance can be given as to the market price
of Webster Common Stock at the time of the Merger. 

COMPARATIVE PER SHARE DATA

     Following are certain  comparative  selected  historical  per share data of
Webster and of DS Bancor,  pro forma  combined  per share data of Webster and DS
Bancor, and equivalent pro forma per share data of DS Bancor. The financial data
is based on, and should be read in conjunction with, the historical consolidated
financial  statements  and the notes thereto of Webster and of DS Bancor and the
pro forma combined  financial  statements and the notes thereto  appearing in or
incorporated by reference elsewhere into this Joint Proxy  Statement/Prospectus.
All per share data of Webster,  DS Bancor and pro forma are presented on a fully
diluted  basis  and have been  adjusted  retroactively  to give  effect to stock
dividends.  The pro forma data is not  necessarily  indicative  of results which
will be obtained on a combined  basis.  The pro forma data has not been adjusted
to reflect  any of the  improvements  in  operating  efficiencies  that  Webster
anticipates may occur in the future due to the Merger.

(a)  Excludes  non-recurring  expenses of $5.2  million,  $6.4  million and $5.7
     million for the nine months  ended  September  30, 1996 and the years ended
     December 31, 1995 and 1994, respectively.

(b)  Does not give  effect  to  additional  income  in 1993  resulting  from the
     cumulative  effect  of change in method  of  accounting  for  income  taxes
     adopted  by each of  Webster  and DS  Bancor  in  1993 in  accordance  with
     Financial  Accounting  Standards  Board  Statement of Financial  Accounting
     Standards No. 109 ("FASB 109"),  which  resulted in an increase of $.79 per
     share in Webster's net income for 1993 and an increase of $.51 per share in
     DS Bancor's net income for 1993.

(c)  Pro forma combined amounts shown above reflect the proposed  acquisition of
     DS Bancor on a pooling of  interests  basis for each period shown as if the
     Merger had occurred at the beginning of such period.

(d)  DS  Bancor  equivalent  pro  forma  per share  amounts  are  calculated  by
     multiplying the pro forma combined amounts by the Exchange Ratio calculated
     based on the average daily closing prices per share of Webster Common Stock
     for the 15 consecutive trading days on which shares of Webster Common Stock
     were  actually  traded  prior to  ______________  __, 1996 (the most recent
     practicable    date   prior   to   the   date   of   this    Joint    Proxy
     Statement/Prospectus). See "THE MERGER -- Exchange Ratio."

                                  RISK FACTORS

         DS Bancor  shareholders  should  consider,  among  other  matters,  the
following  factors in voting  upon the  proposal to approve and adopt the Merger
Agreement and the Merger provided for therein, consummation of which will result
in holders of DS Bancor Common Stock  receiving  shares of Webster Common Stock.
These factors also should be considered by Webster shareholders in voting on the
proposal  to  approve  the  issuance  of  Webster  Common  Stock  to  DS  Bancor
shareholders as part of the Merger.

GROWTH THROUGH ACQUISITIONS

         Since 1991, Webster has experienced significant growth,  primarily as a
result of  acquisitions  of other  financial  institutions.  In September  1991,
Webster Bank acquired  certain assets and  liabilities of Suffield Bank from the
FDIC in an assisted transaction. In that acquisition, which was accounted for as
a purchase transaction, among other things, Webster Bank assumed $247 million of
deposit  liabilities.  In 1992, Webster Bank acquired most of the assets, all of
the deposits and certain other  liabilities  of First  Constitution,  New Haven,
Connecticut,  from  the  FDIC  in  an  assisted  transaction.  This  acquisition
increased  Webster Bank's assets by $1.3 billion and, at that time,  doubled the
number of its  banking  offices.  The First  Constitution  acquisition  also was
accounted for as a purchase transaction.

         In March 1994,  Webster completed a  conversion/acquisition  of Bristol
Savings Bank ("Bristol").  Upon that  acquisition,  which was accounted for as a
purchase  transaction,  Webster acquired five full-service  banking offices with
$453 million in deposits, as well as Bristol's mortgage banking subsidiary. Also
in 1994, Webster acquired Shoreline in a transaction  accounted for as a pooling
of interests.  Shoreline had total assets of $51 million, deposit liabilities of
$47 million and shareholders' equity of $4 million.

         In November 1995,  Webster  acquired  Shelton,  the holding  company of
Shelton Savings Bank, a state-chartered  savings bank  headquartered in Shelton,
Connecticut.  In that  transaction,  which was  accounted  for as a  pooling  of
interests,  Webster acquired from Shelton  approximately $298 million of assets,
including $224 million of loans, and approximately $273 million of deposits.

         In February  1996,  Webster  acquired 20 branch  banking  offices  from
Shawmut.  In that  transaction,  which was accounted for as a purchase,  Webster
Bank assumed  approximately $845 million in deposits and acquired  approximately
$586 million in loans.

LEGISLATIVE AND GENERAL REGULATORY DEVELOPMENTS

         Webster is subject to various regulatory  restrictions as a savings and
loan holding  company,  primarily by the OTS and the  Connecticut  Commissioner.
Webster  Bank is,  and  following  the  Merger  will be,  subject  to  extensive
regulation by the OTS as its primary federal regulator and also to regulation as
to  certain  matters  by the  FDIC.  The  OTS and  FDIC  have  adopted  numerous
regulations and undertaken other regulatory initiatives, and further regulations
and initiatives may be adopted.  Future  legislation or regulatory  developments
could have an adverse effect on Webster Bank.

         Under recently  enacted  legislation,  the Secretary of the Treasury is
required to report to Congress no later than March 31, 1997 with  respect to the
development  of  a  common  charter  for  all  federal  and  national  financial
institutions  and the abolition of separate and distinct  charters between banks
and savings  associations.  If legislation  with respect to the development of a
common  charter is enacted,  Webster Bank may be required to convert its federal
savings  bank charter to either a new federal type of bank charter or to a state
depository  institution  charter.  Future legislation also may result in Webster
becoming  regulated at the holding  company  level by the Federal  Reserve Board
rather than by the OTS.  Regulation  by the Federal  Reserve Board could subject
Webster to capital  requirements that are not currently applicable to Webster as
a holding

                                      -21-


company under OTS regulation and may result in statutory limitations on the type
of business activities in which Webster may engage at the holding company level,
which business  activities  currently are not  restricted.  Webster is unable to
predict whether such legislation will be enacted.

SOURCES OF FUNDS FOR CASH DIVIDENDS

         The principal sources of funds for Webster's payments of cash dividends
on the Webster  Common Stock and its Series B Stock,  as well as for the payment
of principal and interest on its $40 million  principal  amount of 8 3/4% Senior
Notes due 2000 (the "Senior  Notes"),  are cash  dividends from Webster Bank and
liquid  assets at the holding  company  level.  At September  30,  1996,  at the
holding company level, Webster had liquid investments of $23.1 million.  Webster
Bank is, and  following  the  Merger  will be,  subject  to  certain  regulatory
requirements  that affect its  ability to pay cash  dividends  to  Webster.  The
Series B Stock  ranks prior to the  Webster  Common  Stock as to payment of cash
dividends.  In addition,  the Senior Notes contain certain covenants that affect
Webster's  ability  to pay cash  dividends  on the  Webster  Common  Stock.  See
"DESCRIPTION OF WEBSTER CAPITAL STOCK AND COMPARISON OF SHAREHOLDER  RIGHTS" and
"MARKET PRICES AND DIVIDENDS."

EFFECT OF INTEREST RATE FLUCTUATIONS

         Webster's  consolidated  results of operations depend to a large extent
on the  level  of its net  interest  income,  which  is the  difference  between
interest income from interest-earning assets (such as loans and investments) and
interest  expense  on   interest-bearing   liabilities  (such  as  deposits  and
borrowings).  If  interest-rate  fluctuations  cause  Webster's cost of funds to
increase  faster than the yield on its  interest-bearing  assets,  net  interest
income  will  be  reduced.   Webster  measures  its  interest-rate   risk  using
simulation,  price  elasticity  and other methods. 

         Based  on  Webster's   asset/liability   mix  at  September  30,  1996,
management's  simulation  analysis  of the effects of  changing  interest  rates
projects that an instantaneous  +/-200 basis point fluctuation in interest rates
would decrease net interest income for the following  twelve months by less than
5%. Based on Webster's  asset-liability mix at September 30, 1996, management of
Webster  believes its interest  risk is  reasonable.  Management of Webster also
believes  that the  addition  of DS  Bancor's  assets and  liabilities  does not
significantly alter the pro forma interest rate risk of Webster.

         While Webster uses various monitors of interest-rate  risk,  Webster is
unable to predict future  fluctuations  in interest rates or the specific impact
thereof.  The market  values of most of its  financial  assets are  sensitive to
fluctuations in market interest rates. Fixed-rate  investments,  mortgage-backed
securities and mortgage loans decline in value and fixed-rate  liabilities  rise
in  value  as  interest   rates  rise.   Although   Webster's   investment   and
mortgage-backed securities portfolios have grown in recent quarters, most of the
growth has been in  adjustable-rate  securities  or short-term  securities  with
durations of less than three years.

         Changes  in  interest  rates  also  can  affect  the  amount  of  loans
originated   by  Webster,   as  well  as  the  value  of  its  loans  and  other
interest-earning  assets and its  ability  to realize  gains on the sale of such
assets and  liabilities.  The  extent to which  borrowers  prepay  loans also is
affected by prevailing  interest rates. When interest rates increase,  borrowers
are less likely to prepay their loans;  whereas,  when interest rates  decrease,
borrowers are more likely to prepay loans. Funds generated by prepayments may be
invested at a lower rate. Prepayments may adversely affect the value of mortgage
loans,  the levels of such assets  that are  retained  in their  portfolio,  net
interest

                                      -22-



income and loan servicing  income.  Similarly,  prepayments  on  mortgage-backed
securities also may affect  adversely the value of these securities and interest
income.

         Increases in interest  rates may cause  depositors  to shift funds from
accounts that have a comparatively  lower cost such as regular savings  accounts
to accounts with a higher cost such as certificates  of deposit.  If the cost of
deposits  increases  at a rate that is greater  than the  increase  in yields on
interest-earning  assets,  the  interest-rate  spread  is  negatively  affected.
Changes in the asset and liability mix also affect the interest-rate spread.

                                DS BANCOR MEETING

MATTERS TO BE CONSIDERED AT THE DS BANCOR MEETING

         This Joint  Proxy  Statement/Prospectus  is first  being  mailed to the
holders of DS Bancor Common Stock on or about  ______________  ___, 1996, and is
accompanied by a proxy card  furnished in connection  with the  solicitation  of
proxies by the DS Bancor  Board of Directors  for use at the DS Bancor  Meeting.
The DS Bancor  Meeting is scheduled to be held on  ______________  ___, 1997, at
_____ a.m.,  at  _____________________________________,  Connecticut.  At the DS
Bancor  Meeting,  the holders of DS Bancor  Common Stock will  consider and vote
upon: (i) the proposal to approve and adopt the Merger  Agreement and the Merger
provided for therein,  and (ii) such other  business as may properly come before
the DS Bancor Meeting,  or any adjournments or postponements  thereof including,
without  limitation,  a motion to adjourn the DS Bancor  Meeting to another time
and/or  place for the  purpose  of  soliciting  additional  proxies  in order to
approve the Merger Agreement and the Merger provided for therein or otherwise.

RECORD DATE AND VOTING

         The Board of  Directors of DS Bancor has fixed the close of business on
____________ ___, 1996 as the DS Bancor Record Date for the determination of the
holders of DS Bancor Common Stock  entitled to receive  notice of and to vote at
the DS Bancor  Meeting.  Only holders of record of DS Bancor Common Stock at the
close of business on that date will be entitled to vote at the DS Bancor Meeting
or at any adjournment or postponement  thereof.  At the close of business on the
DS Bancor  Record Date,  there were  _________  shares of DS Bancor Common Stock
outstanding and entitled to vote at the DS Bancor Meeting, held by approximately
____  shareholders  of  record.  No shares of  preferred  stock of DS Bancor are
issued and outstanding.

         Each holder of DS Bancor Common Stock on the DS Bancor Record Date will
be entitled to one vote for each share held of record upon each matter  properly
submitted  at the  DS  Bancor  Meeting  or at any  adjournment  or  postponement
thereof.  The  presence,  in  person  or by proxy,  of the  holders  of at least
one-third of the shares of DS Bancor  Common Stock  issued and  outstanding  and
entitled  to be voted at the DS Bancor  Meeting is  necessary  to  constitute  a
quorum.  Abstentions and broker non-votes will be included in the calculation of
the  number of shares  represented  at the DS Bancor  Meeting  for  purposes  of
determining  whether a quorum has been  achieved.  Since  approval of the Merger
Agreement requires the affirmative vote of the holders of at least two-thirds of
the outstanding  shares of DS Bancor Common Stock entitled to be voted at the DS
Bancor Meeting,  abstentions and broker non-votes will have the same effect as a
vote against the Merger Agreement.

         If a quorum is not  obtained,  or if fewer  shares of DS Bancor  Common
Stock are voted in favor of the proposal  for  approval of the Merger  Agreement
than the number required for approval, it is expected that the DS Bancor Meeting
will be  adjourned  for the purpose of allowing  additional  time for  obtaining
additional  proxies.  In  such  event,  proxies  will be  voted  to  approve  an
adjournment, except for proxies as to which instructions have been given to vote
against  the Merger  Agreement.  The holders of a majority of the shares cast on
the matter at the DS Bancor Meeting would be required to approve any adjournment
of the DS Bancor Meeting.

         If the  enclosed  proxy card is properly  executed  and  received by DS
Bancor  in time to be voted at the DS Bancor  Meeting,  the  shares  represented
thereby  will be  voted in  accordance  with the  instructions  marked  thereon.
EXECUTED PROXIES WITH NO INSTRUCTIONS  INDICATED THEREON WILL BE VOTED "FOR" THE
PROPOSAL TO APPROVE AND ADOPT THE MERGER  AGREEMENT AND THE MERGER  PROVIDED FOR
THEREIN.

         The Board of Directors  of DS Bancor is not aware of any matters  other
than the  proposal  to  approve  and adopt the Merger  Agreement  and the Merger
provided for therein (or a proposal to adjourn or postpone the DS Bancor Meeting
as necessary) that may be properly brought before the

                                      -24-



DS Bancor  Meeting.  If any other  matters  properly  come  before the DS Bancor
Meeting,  the  persons  named in the  accompanying  proxy  will vote the  shares
represented by all properly  executed  proxies on such matters in such manner as
shall be determined by a majority of the Board of Directors of DS Bancor.

         DS BANCOR  SHAREHOLDERS  SHOULD NOT FORWARD ANY DS BANCOR  COMMON STOCK
CERTIFICATES  WITH  THEIR  PROXY  CARDS.  IF THE  MERGER IS  CONSUMMATED,  STOCK
CERTIFICATES  SHOULD BE DELIVERED IN ACCORDANCE WITH INSTRUCTIONS SET FORTH IN A
LETTER  OF  TRANSMITTAL  WHICH  WOULD BE SENT TO DS BANCOR  SHAREHOLDERS  BY THE
EXCHANGE AGENT PROMPTLY AFTER THE EFFECTIVE TIME.

VOTE REQUIRED; REVOCABILITY OF PROXIES

         The affirmative vote of at least  two-thirds of the outstanding  shares
of DS Bancor  Common  Stock  entitled  to be voted at the DS Bancor  Meeting  is
required  in order to  approve  and adopt the  Merger  Agreement  and the Merger
provided for therein.

         THE  REQUIRED  VOTE OF THE DS BANCOR  SHAREHOLDERS  WITH RESPECT TO THE
MERGER  AGREEMENT  IS BASED UPON THE TOTAL  NUMBER OF  OUTSTANDING  SHARES OF DS
BANCOR COMMON STOCK AND NOT UPON THE NUMBER OF SHARES WHICH ARE ACTUALLY  VOTED.
ACCORDINGLY,  THE  FAILURE TO SUBMIT A PROXY CARD OR TO VOTE IN PERSON AT THE DS
BANCOR MEETING OR THE ABSTENTION FROM VOTING BY A SHAREHOLDER WILL HAVE THE SAME
EFFECT AS A VOTE  "AGAINST"  THE MERGER  AGREEMENT  AND THE MERGER  PROVIDED FOR
THEREIN.

         All of the directors of DS Bancor, who beneficially owned, as of the DS
Bancor  Record Date,  an aggregate of _______  shares of DS Bancor  Common Stock
(excluding all stock options) or approximately ___% of the outstanding shares of
DS Bancor, have entered into the Stockholder  Agreement with Webster pursuant to
which  they  have  each  agreed,   among  other  things,   to  certain  transfer
restrictions  and to vote all shares of DS Bancor  Common  Stock with respect to
which  they  have  the  right  to  vote  (whether  owned  as of the  date of the
Stockholder  Agreement or thereafter acquired) in favor of the Merger Agreement,
the Merger and the other  transactions  contemplated by the Merger Agreement and
against  any  third  party  merger  proposal  (unless  the DS  Bancor  Board  of
Directors, following receipt of written advice of counsel, reasonably determines
that voting  against  such plan or  proposal  would  constitute  a breach of the
exercise of its  fiduciary  duty because  such plan or proposal  would be in the
best interest of DS Bancor  shareholders).  The executive  officers of DS Bancor
and Derby also entered into the Stockholder  Agreement  insofar as it relates to
transfer  restrictions and certain other matters. No separate  consideration was
paid to any of the  directors or the  executive  officers for entering  into the
Stockholder  Agreement.  Webster  required  that the  Stockholder  Agreement  be
executed as a condition to Webster entering into the Merger Agreement.

         The  presence  of a  shareholder  at the DS  Bancor  Meeting  will  not
automatically revoke such shareholder's proxy. However, a shareholder may revoke
a proxy at any time  prior to its  exercise  by (i)  delivering  to Ann  Mester,
Secretary,  DS Bancor,  Inc., 33 Elizabeth Street,  Derby,  Connecticut 06418, a
written notice of revocation prior to the DS Bancor Meeting,  (ii) delivering to
DS Bancor prior to the DS Bancor  Meeting a duly executed  proxy bearing a later
date, or (iii) attending the DS Bancor Meeting and voting in person.


         The  obligations  of DS Bancor  and  Webster to  consummate  the Merger
Agreement  are subject,  among other things,  to the  condition  that the Merger
Agreement and the Merger shall have been approved and adopted by the affirmative
vote of the  holders  of at least  two-thirds  of the  outstanding  shares of DS
Bancor Common Stock  entitled to vote  thereon.  The approval of the issuance of
additional Webster Common Stock in connection with the transactions contemplated
by the Merger  Agreement is also required.  See "THE MERGER -- Conditions to the
Merger."

                                      -25-




SOLICITATION OF PROXIES


In addition to  solicitation  by mail,  directors,  officers and employees of DS
Bancor  may  solicit  proxies  for  the  DS  Bancor  Meeting  from  shareholders
personally or by telephone or telegram without additional remuneration therefor.
In addition,  Webster, on behalf of itself and DS Bancor, has retained D.F. King
& Co., Inc., a proxy solicitation firm, to assist in such solicitation.  The fee
to be paid to such firm is an  aggregate  $8,500 for both Webster and DS Bancor,
plus reasonable out-of-pocket expenses. Such fee will be proportionately paid by
Webster and DS Bancor.  DS Bancor  will also make  arrangements  with  brokerage
firms and other custodians,  nominees and fiduciaries to send proxy materials to
their principals and will reimburse such parties for their expenses in doing so.
The cost of soliciting proxies will be paid by DS Bancor.

                                 WEBSTER MEETING

MATTERS TO BE CONSIDERED AT THE WEBSTER MEETING

         This Joint  Proxy  Statement/Prospectus  is first  being  mailed to the
holders  of  Webster  capital  stock on or about  _________  ___,  1996,  and is
accompanied by a proxy card  furnished in connection  with the  solicitation  of
proxies by the Webster  Board of Directors for use at the Webster  Meeting.  The
Webster  Meeting is scheduled to be held on  ______________  ___, 1997, at _____
a.m., at ________________________________,  Connecticut. At the Webster Meeting,
the  holders  of  Webster  Common  Stock will  consider  and vote upon:  (i) the
proposal to approve the  issuance of up to  4,681,658  shares of Webster  Common
Stock in connection with the acquisition of DS Bancor by Webster pursuant to the
Merger  Agreement,  (ii) the  proposal to approve  the  amendment  to  Webster's
Restated  Certificate of Incorporation to increase Webster's  authorized capital
stock by increasing the number of authorized shares of Webster Common Stock from
14,000,000  to  30,000,000,  and (iii) such other  business as may properly come
before the  Webster  Meeting,  or any  adjournments  or  postponements  thereof,
including,  without  limitation,  a motion to  adjourn  the  Webster  Meeting to
another time and/or place for the purpose of  soliciting  additional  proxies in
order to approve the issuance of Webster Common Stock or otherwise.

RECORD DATE AND VOTING

         The Board of  Directors  of Webster  has fixed the close of business on
______________ __, 1996, as the Webster Record Date for the determination of the
holders of Webster Common Stock entitled to receive notice of and to vote at the
Webster Meeting.  Only holders of record of Webster Common Stock at the close of
business on that date will be entitled to vote at the Webster  Meeting or at any
adjournment  or  postponement  thereof.  At the close of business on the Webster
Record Date, there were _____________ shares of Webster Common Stock outstanding
and  entitled  to  vote  at the  Webster  Meeting,  held  by  approximately  ___
shareholders of record.  Holders of Webster's Series B Stock are not entitled to
vote at the Webster Meeting.

         Each holder of Webster  Common Stock on the Webster Record Date will be
entitled  to one vote for each share held of record  upon each  matter  properly
submitted at the Webster Meeting or at any adjournment or postponement  thereof.
The presence,  in person or by proxy,  of at least  one-third of the outstanding
shares of Webster Common Stock issued and  outstanding  and entitled to be voted
at the Webster  Meeting is necessary to  constitute  a quorum.  Abstentions  and
broker  non-votes  will be included in the  calculation  of the number of shares
represented at the Webster Meeting for purposes of determining  whether a quorum
has been achieved.  Abstentions  will have the same effect as a vote against the
amendment to Webster's Restated Certificate of Incorporation.

         Each participant in the Webster employee stock ownership plan ("Webster
ESOP") will  receive a form to be used to instruct  the  trustees of the Webster
ESOP how to vote the  Webster  Common  Stock  held by the  Webster  ESOP that is
allocated to such  participant.  The Webster ESOP provides that each participant
shall  direct the trustee of the Webster  ESOP as to the manner in which  shares
allocated to such  participant  are to be voted.  The Webster ESOP provides that
the trustee will vote such shares as instructed.  The Webster ESOP also provides
that the trustee of the Webster ESOP shall vote all  allocated  shares for which
the trustee has not received  directions from the applicable  participant in its
sole  discretion.  The Webster  ESOP  provides  that the trustee  shall vote all
unallocated  shares in the same  manner and  proportion  in which the  allocated
shares are voted  (taking  into  account  any such  shares that are voted by the
trustee because no instructions were received from the participant). The trustee
of the Webster ESOP is Fleet Bank, N.A.

         The  directions  of  participants  regarding  the  voting of the shares
allocated to them will not be disclosed to Webster,  DS Bancor or the trustee of
the  Webster  ESOP,  and  will be  tabulated  by  ______________,  which  is the
[recordkeeper] for the Webster ESOP.

         To be effective,  directions to the trustee of the Webster ESOP must be
received by the  [recordkeeper] at  __________________________,  ATTN.:  Webster
ESOP Vote, by the close of business

                                      -27-



(5:00  p.m.  E.S.T.) on  _____________  ___,  1997.  Directions  to the  trustee
received after the close of business on ______________  __, 1997, or received at
a different address, will not be effective.  A participant or beneficiary in the
Webster  ESOP who is  otherwise a Webster  shareholder  should (i)  complete and
return  directions to the Webster ESOP trustee with respect to shares of Webster
Common Stock held by the Webster ESOP that are allocated to such participant and
(ii) complete and return the enclosed proxy with respect to such other shares of
Webster Common Stock.

         The Merger is conditioned  on the approval by the Webster  shareholders
of the issuance of additional  shares of Webster Common Stock in connection with
the Merger Agreement, which approval requires the affirmative vote of a majority
of the total votes cast on the proposal by the Webster shareholders  entitled to
vote  at the  Webster  Meeting.  Approval  by the  Webster  shareholders  of the
issuance  of the  additional  shares  is also  necessary  under the rules of The
Nasdaq  National  Market.  As of the  Webster  Record  Date,  of the  shares  of
additional  Webster  Common  Stock  proposed to be issued as part of the Merger,
_____*_____ shares of Webster Common Stock would be issued to the holders of the
_____*_____  then  outstanding  shares of DS Bancor  Common Stock and  ____*____
shares of Webster  Common Stock would be issued or reserved  for  issuance  with
respect to the exercise of the ___*___ then  outstanding  options to purchase DS
Bancor Common Stock held by directors, officers and employees of DS Bancor.

         Approval of the proposal to amend  Webster's  Restated  Certificate  of
Incorporation to increase  Webster's  authorized capital stock by increasing the
number  of  authorized  shares  of  Webster  Common  Stock  from  14,000,000  to
30,000,000 requires the affirmative vote of a majority of the outstanding shares
of Webster Common Stock entitled to vote at the Webster Meeting.

         If a quorum is not obtained, or if fewer shares of Webster Common Stock
are voted in favor of approval of the proposal  authorizing  the issuance of the
additional Webster Common Stock in connection with the Merger Agreement than the
number  required for approval,  it is expected that the Webster  Meeting will be
adjourned for the purpose of allowing  additional time for obtaining  additional
proxies. In such event, proxies will be voted to approve an adjournment,  except
for  proxies  as to which  instructions  have  been  given to vote  against  the
proposal  authorizing the issuance of the additional  Webster Common Stock.  The
holders  of a  majority  of the  shares  cast at the  Webster  Meeting  would be
required to approve any adjournment of the Webster Meeting.

         If the enclosed proxy card is properly executed and received by Webster
in time to be voted at the Webster Meeting,  the shares represented thereby will
be voted in accordance with the  instructions  marked thereon.  EXECUTED PROXIES
WITH NO  INSTRUCTIONS  INDICATED  THEREON  WILL BE VOTED  "FOR"  APPROVAL OF THE
PROPOSAL  AUTHORIZING  THE ISSUANCE OF THE  ADDITIONAL  WEBSTER  COMMON STOCK IN
CONNECTION  WITH  THE  MERGER  AGREEMENT  AND  "FOR"  APPROVAL  OF THE  PROPOSAL
AUTHORIZING THE AMENDMENT TO WEBSTER'S RESTATED CERTIFICATE OF INCORPORATION.

         The Board of  Directors  of Webster is not aware of any  matters  other
than the  proposal to approve the issuance of the  additional  shares of Webster
Common Stock in  connection  with the Merger  Agreement or the proposal to amend
Webster's  Restated  Certificate  of  Incorporation  to  increase  the number of
authorized shares of Webster Common Stock (or a proposal to adjourn or

the  Webster  Meeting.  If any other  matters  properly  come before the Webster
Meeting,  the  persons  named in the  accompanying  proxy  will vote the  shares
represented by all properly  executed  proxies on such matters in such manner as
shall be determined by a majority of the Board of Directors of Webster.

VOTE REQUIRED; REVOCABILITY OF PROXIES

         The  affirmative  vote of a  majority  of the total  votes  cast on the
proposal  at the Webster  Meeting is  required  to approve  the  issuance of the
additional  shares of Webster Common Stock in connection with Merger  Agreement.
The affirmative  vote of a majority of the outstanding  shares of Webster Common
Stock  entitled  to vote at the  Webster  Meeting is  required  to  approve  the
amendment to Webster's  Restated  Certificate of  Incorporation  to increase the
number  of  authorized  shares  of  Webster  Common  Stock  from  14,000,000  to
30,000,000.

         THE  REQUIRED  VOTE OF THE  WEBSTER  SHAREHOLDERS  WITH  RESPECT TO THE
AMENDMENT OF WEBSTER'S  RESTATED  CERTIFICATE OF INCORPORATION IS BASED UPON THE
TOTAL  NUMBER OF  OUTSTANDING  SHARES OF WEBSTER  COMMON  STOCK AND NOT UPON THE
NUMBER OF SHARES WHICH ARE ACTUALLY VOTED. ACCORDINGLY,  THE FAILURE TO SUBMIT A
PROXY CARD OR TO VOTE IN PERSON AT THE WEBSTER  MEETING OR THE  ABSTENTION  FROM
VOTING BY A  SHAREHOLDER  WILL  HAVE THE SAME  EFFECT  AS A VOTE  "AGAINST"  THE
AMENDMENT TO WEBSTER'S RESTATED CERTIFICATE OF INCORPORATION.

         Approval  of  the  amendment  to  Webster's  Restated   Certificate  of
Incorporation is not a condition to the Merger Agreement.

         The  presence  of  a  shareholder  at  the  Webster  Meeting  will  not
automatically revoke such shareholder's proxy. However, a shareholder may revoke
a proxy at any time prior to its  exercise by (i)  delivering  to Lee A. Gagnon,
Executive  Vice  President,  Chief  Operating  Officer  and  Secretary,  Webster
Financial Corporation,  Webster Plaza,  Waterbury,  Connecticut 06702, a written
notice of revocation  prior to the Webster  Meeting,  (ii) delivering to Webster
prior to the Webster  Meeting a duly  executed  proxy  bearing a later date,  or
(iii) attending the Webster Meeting and voting in person.

         The  obligations  of Webster and DS Bancor to consummate the Merger are
subject,  among other things,  to the condition  that the issuance of additional
shares of Webster Common Stock shall have been approved by the affirmative  vote
of a majority  of the total votes cast on the  proposal.  Approval of the Merger
Agreement  and the  Merger  provided  for  therein  by the  affirmative  vote of
two-thirds of the outstanding  shares of DS Bancor Common Stock entitled to vote
thereon is also required. See "THE MERGER -- Conditions to the Merger."

         As of the Webster  Record Date,  the Webster ESOP owned 409,592  shares
(____%) of the Webster  Common  Stock  outstanding  and  entitled to vote at the
Webster Meeting. Of the shares of Webster Common Stock held by the Webster ESOP,
190,963 have been  allocated to the accounts of  participants  as of the Webster
Record Date and 218,629 remain unallocated.  The Webster ESOP provides that each
participant  shall  direct the trustee of the  Webster  ESOP as to the manner in
which shares  allocated  to such  participant  are to be voted.  The trustee has
discretion  to vote  unallocated  shares  and  allocated  shares  for  which  no
instructions are received. See "-- Record Date and Voting."

SOLICITATION OF PROXIES

         In addition to solicitation by mail, directors,  officers and employees
of Webster  may  solicit  proxies  for the  Webster  Meeting  from  shareholders

                                   THE MERGER


         The  information  in this  Section  is  qualified  in its  entirety  by
reference  to the  full  text of the  Merger  Agreement  (including  each of the
exhibits thereto),  the Stockholder  Agreement and the Option Agreement,  all of
which are  incorporated  herein by reference and the material  features of which
are  described  in this Joint Proxy  Statement/Prospectus.  A copy of the Merger
Agreement (including each of exhibits thereto) and the other documents described
in this Joint  Proxy  Statement/Prospectus  will be  provided  promptly  without
charge upon oral or written request  addressed to Lee A. Gagnon,  Executive Vice
President, Chief Operating Officer and Secretary, Webster Financial Corporation,
Webster Plaza, Waterbury, Connecticut 06702, telephone (203) 578-2217.


THE PARTIES

         The Merger Agreement was entered into among Webster,  Merger Sub and DS
Bancor.  The Merger  Agreement  provides  for,  among  other  things,  Webster's
acquisition  of DS Bancor  through  the  merger of Merger  Sub,  a  wholly-owned
subsidiary of Webster, into DS Bancor.

         Webster.  Webster is a Delaware  corporation and the holding company of
Webster  Bank,  its  wholly-owned  federal  savings  bank  subsidiary  which  is
headquartered  in  Waterbury,  Connecticut.  Deposits  at Webster  Bank are FDIC
insured.  Through  Webster Bank,  Webster  currently  serves  customers  from 63
banking  offices  located  in New Haven,  Fairfield,  Litchfield,  Hartford  and
Middlesex  Counties in Connecticut.  Webster's  focus is on providing  financial
services to  individuals,  families and  businesses.  Webster  emphasizes  three
business lines - consumer banking,  business banking and mortgage banking;  each
supported by  centralized  administration,  marketing,  finance and  operations.
Webster  Bank's  goal is to provide  banking  services  that are fairly  priced,
reliable and convenient.

         At September 30, 1996,  Webster had total  consolidated  assets of $4.0
billion,  total  deposits of $3.0 billion,  and  shareholders'  equity of $216.7
million or 5.44% of total  assets.  At  September  30,  1996,  Webster had loans
receivable,  net of $2.5 billion,  which  included  $1.9 billion in  residential
mortgage loans,  $213.3 million in commercial real estate loans,  $165.5 million
in  commercial  and  industrial  loans and  $237.7  million  in  consumer  loans
(consisting primarily of home equity loans). In addition, Segregated Assets, net
were $82.9 million at September 30, 1996, which were comprised of commercial and
industrial,  commercial  real estate and  multi-family  loans.  At September 30,
1996,  nonaccrual loans and other real estate owned ("OREO") were $33.7 million.
At that date,  Webster's  allowance for loan losses was $34.4 million, or 155.1%
of nonaccrual  loans, and its total allowance for loan and OREO losses was $34.9
million,  or  102.1%  of  nonaccrual  loans  and  OREO.  Additional  information
regarding  Webster is incorporated  herein by reference.  See  "INCORPORATION OF
CERTAIN DOCUMENTS BY REFERENCE."

         Webster, as a holding company, is regulated primarily by the OTS at the
federal level and by the  Connecticut  Commissioner.  Webster Bank, as a federal
savings bank, is regulated primarily by the OTS and as to certain matters by the
FDIC.

         Merger  Sub.  Merger  Sub, a Delaware  corporation,  is a  wholly-owned
subsidiary  of Webster  formed  solely to  facilitate  the Merger.  The separate
corporate existence of Merger Sub will terminate upon the Merger.

         DS Bancor.  DS  Bancor,  a Delaware  corporation,  is the bank  holding
company of Derby, a Connecticut-chartered  savings bank  headquartered in Derby,
Connecticut.  Deposits at Derby are FDIC insured.  Through  Derby,  DS Bancor is
engaged primarily in the business of attracting deposits from the general public
and investing  those funds primarily in residential  mortgage loans.  Derby also
makes commercial mortgage and consumer loans. Through Derby, DS Bancor currently

Connecticut. Its general market area is western New Haven, eastern Fairfield and

         At September 30, 1996, DS Bancor had total consolidated  assets of $1.3
billion,  total  deposits of $1.0  billion,  and  shareholders'  equity of $86.5
million,  or 6.87% of total  assets.  At September 30, 1996, DS Bancor had loans
receivable,  net of $877.3 million, which included $675.3 million in residential
mortgage loans, $63.1 million in commercial real estate loans and $129.8 million
in home equity  credit lines and consumer  installment  loans.  At September 30,
1996, nonperforming loans and OREO were $20.4 million. At that date, DS Bancor's
allowance for loan losses was $7.4 million, or 46.5% of nonperforming loans, and
its total  allowance  for loan  losses  and OREO was $7.4  million,  or 36.2% of
nonperforming  loans and OREO.  Additional  information  regarding  DS Bancor is
incorporated  herein by reference.  See  "INCORPORATION  OF CERTAIN DOCUMENTS BY
REFERENCE."

         DS Bancor, as a holding company,  is regulated primarily by the Federal
Reserve Board at the federal level and by the Connecticut  Commissioner.  Derby,
as a state-chartered savings bank, is regulated by the Connecticut  Commissioner
and by the FDIC.

BACKGROUND OF THE MERGER

         In  February  1996,  the DS  Bancor  Board  of  Directors  appointed  a
Strategic  Planning  Committee  to, among other  things,  review and analyze the
various  strategic  alternatives  available  to DS  Bancor,  including,  but not
limited to, following or modifying DS Bancor's existing business plan in pursuit
of long-term growth strategy or pursuing a possible merger partner or sale of DS
Bancor.  The  members  of  the  Strategic  Committee  were  Messrs.   Sponheimer
(Chairman), Archer, Daddona, DiAdamo and Mills.

         In March 1996, the Strategic  Planning Committee engaged Alex. Brown to
serve as DS Bancor's financial advisor to evaluate strategic  alternatives of DS
Bancor, including a possible third party sale of DS Bancor.

         In April 1996,  after Alex. Brown completed its strategic  review,  the
Strategic Planning Committee authorized Alex. Brown to identify potential merger
partners and  acquirors of DS Bancor and to prepare and  distribute  information
packages  with  respect  to DS  Bancor  to  such  parties  in  order  to  obtain
expressions of interest as to a potential transaction with DS Bancor.

         In June  1996,  Alex.  Brown  contacted  a  total  of 10  national  and
super-regional  banks headquartered in New York, New Jersey and New England that
were identified by Alex. Brown as potentially interested in acquiring or merging
with DS Bancor and as the most likely  candidates to pay the highest  premium to
acquire or merge with DS Bancor. Of these 10, nine  entered into confidentiality
agreements with DS Bancor and were furnished with information  packages. In July
1996, DS Bancor received  preliminary  indications of interest from three of the
nine potential transaction  candidates.  The preliminary indications of interest
each were for acquisition  transactions in which shareholders of DS Bancor would
receive either stock or cash. The stated per share  valuation of the preliminary
indications of interest ranged to as high as $41.00,  subject to increase in the
event  of  certain  asset  sales  and  expense  reductions.  In each  case,  the
preliminary indications of interest were subject to completion of an on-site due
diligence review of DS Bancor.

         In August  1996,  DS  Bancor's  Board of  Directors  authorized  senior
management  to work with Alex.  Brown to schedule  on-site due  diligence by the
parties who had expressed an interest in acquiring DS Bancor. Also during August
1996,  Webster,  which  had  previously  informally  expressed  an  interest  in
acquiring DS Bancor, was contacted.  Following such contact,  Webster executed a
confidentiality  agreement  and was  furnished  with a copy  of the  information
package  furnished  to  other  potential  acquirors.   Following  that,  Webster
furnished  DS Bancor  with a  preliminary  indication  of interest at $43.00 per
share in a  stock-for-stock  exchange,  subject to  completion of an on-site due
diligence review of DS Bancor. The due diligence by all potential  acquirors was
conducted during the latter weeks of August and early September 1996.


                                      -32-



         Following  completion  of the due diligence  reviews,  the four parties
submitted revised acquisition  proposals.  Based upon its evaluation of the four
proposals,  on September  27, 1996,  the Board of  Directors  authorized  senior
management  and  Alex.  Brown to  proceed  with  negotiation  of an  acquisition
agreement with Webster.  On October 7, 1996, upon consideration of the strategic
alternatives  available  to DS  Bancor,  the  Board of  Directors  approved  the
acquisition of DS Bancor by Webster and authorized the execution and delivery by
DS Bancor of the Merger Agreement.

RECOMMENDATION OF THE DS BANCOR BOARD OF DIRECTORS AND REASONS FOR THE MERGER

         The DS  Bancor  Board of  Directors  unanimously  approved  the  Merger
Agreement and the Merger  provided for therein and determined that the Merger is
fair to, and in the best  interests of, DS Bancor and its  shareholders.  THE DS
BANCOR BOARD THEREFORE  UNANIMOUSLY  RECOMMENDS THAT HOLDERS OF DS BANCOR COMMON
STOCK VOTE TO APPROVE AND ADOPT THE MERGER AGREEMENT AND THE MERGER PROVIDED FOR
THEREIN.  The DS Bancor Board believes that the Merger will enable holders of DS
Bancor  Common Stock to realize  increased  value due to the premium over market
price,  net income per share of DS Bancor  Common Stock and book value per share
of DS Bancor Common  Stock,  as provided by the Exchange  Ratio.  The Board also
believes that the Merger may enable DS Bancor's  shareholders  to participate in
opportunities  for  appreciation of Webster Common Stock. See " -- Background of
the Merger" above and " -- Opinion of DS Bancor  Financial  Adviser"  below.  In
reaching  its  decision to approve  the Merger  Agreement,  the DS Bancor  Board
consulted with its legal advisor regarding the legal terms of the Merger and the
DS Bancor Board's  fiduciary  obligations in its  consideration  of the proposed
Merger, its financial advisor,  Alex. Brown, regarding the financial aspects and
fairness of the proposed Merger,  as well as with management of DS Bancor,  and,
without  assigning  any relative or specific  weight,  considered  the following
material factors, both from a short-term and long-term perspective.

                  (i)      The DS Bancor  Board's  familiarity  with, and review
                           of,  DS  Bancor's  business,   financial   condition,
                           results of operations and prospects,  including,  but
                           not limited to, its  potential  growth,  development,
                           productivity and profitability and the business risks
                           associated therewith;

                  (ii)     The current and  prospective  environment in which DS
                           Bancor   operates,   including   national  and  local
                           economic    conditions,    the   highly   competitive
                           environment for financial institutions generally, the
                           increased     regulatory    burden    on    financial
                           institutions,  and the trend toward  consolidation in
                           the financial services industry;

                  (iii)    The potential  appreciation  in market and book value
                           of DS  Bancor  Common  Stock  on  both a  short-  and
                           long-term basis, as a stand alone entity;

                  (iv)     Information   concerning   the  business,   financial
                           condition,  results of operations,  asset quality and
                           prospects of Webster,  including the long-term growth
                           potential of Webster Common Stock,  the future growth
                           prospects  of  Webster,   combined  with  DS  Bancor,
                           following  the  proposed  Merger  and  the  potential
                           synergies  expected  from the Merger and the business
                           risks associated therewith;

                                      -33-



                  (v)      The  potential for  appreciation  and  growth for the
                           market and book value of Webster Common Stock,
                           following the proposed Merger;

                  (vi)     The presentations of Alex. Brown regarding the Merger
                           and the  written  opinion  of  Alex.  Brown  that the
                           merger  consideration is fair, from a financial point
                           of view,  to the  holders of DS Bancor  Common  Stock
                           (see " -- Opinion of Financial Adviser" below);

                  (vii)    The  financial  and  other  significant  terms of the
                           proposed Merger including the terms and conditions of
                           the Merger Agreement and the Option Agreement;

                  (viii)   The benefits of a business  combination with a larger
                           holding company,  such as Webster, with a significant
                           presence in south central Connecticut;

                  (ix)     The expectation that Webster will continue to provide
                           quality  service  to the  communities  and  customers
                           served  by DS Bancor  and  Webster's  capacity,  as a
                           larger  institution  with a larger  capital  base, to
                           provide a wider range of services, enhanced access to
                           credit, and greater convenience to such customers and
                           communities;

                    (x)     The  compatibility  with respect to  businesses  and
                            management philosophies of DS Bancor and Webster and
                            Webster's  strong   commitment  to  the  Connecticut
                            communities it serves;

                  (xi)     The fact that DS Bancor had  conducted  an  extensive
                           solicitation of interest from other likely  potential
                           acquirors of DS Bancor; and

                  (xii)    DS Bancor's  belief that  further  delay in approving
                           the Merger might result in Webster's  withdrawing its
                           acquisition proposal.

RECOMMENDATION OF THE WEBSTER BOARD OF DIRECTORS AND REASONS FOR THE ISSUANCE

         The  Webster  Board  of  Directors   unanimously  approved  the  Merger
Agreement and the Merger  provided for therein and determined that the Merger is
fair to, and in the best interests of, Webster and its shareholders. The Webster
Board also  unanimously  approved  the  issuance  of up to  4,681,658  shares of
Webster Common Stock in connection  with the acquisition of DS Bancor by Webster
pursuant  to the Merger  Agreement.  THE  WEBSTER  BOARD  THEREFORE  UNANIMOUSLY
RECOMMENDS  THAT HOLDERS OF WEBSTER COMMON STOCK VOTE TO APPROVE THE ISSUANCE OF
ADDITIONAL  WEBSTER COMMON STOCK IN CONNECTION  WITH THE MERGER  AGREEMENT.  The
Board of Directors of Webster reviewed financial analyses and recommendations of
Webster's management in considering the Merger.  Webster also consulted with its
outside  financial  advisor,  Merrill Lynch as to certain issues  concerning the
Merger,  including  the fairness of the terms of the Merger.  See "-- Opinion of
Webster Financial Advisor."

         The  Webster  Board of  Directors  concluded  that the  Merger  and the
issuance  of  Webster  Common  Stock in the Merger is in the best  interests  of
Webster and its shareholders because, among other reasons, the Merger would: (i)
enable  Webster to expand its regional  community bank presence in an area which
has been impacted by the recent acquisitions and franchise  consolidation in the
Connecticut   banking  industry,   (ii)  enable  Webster  to  more  quickly  and
economically  fulfill its  strategic  objective to expand its customer  base and
better meet the needs of its  existing  customers  in New Haven,  Fairfield  and
Hartford Counties, and (iii) achieve significant cost savings over the aggregate
expense of Webster's and DS Bancor's operations.

         In reaching  its  conclusion  that the Merger and the issuance are fair
to, and in the best interests of, Webster and its shareholders, Webster Board of
Directors also considered, among other

                                      -34-


things,  the following factors:  (i) its knowledge of the business,  operations,
assets, book value, financial condition,  operating results (including financial
characteristics  such as net worth,  earnings,  deposits,  assets and  financial
ratios) and  prospects of DS Bancor and Derby based on an in-depth due diligence
review;  (ii)  current  industry,  economic  and  market  conditions;  (iii) the
presentation  of Merrill Lynch  regarding the Merger and the written  opinion of
Merrill Lynch; (iv) the expected  long-term  positive effects of the transaction
on Webster's  earnings;  (v) a comparison  of prices known to management to have
been paid in  certain  local and  regional  financial  institution  mergers  and
acquisitions in the recent period; (vi) the terms of the Merger Agreement, which
were  the  product  of  arms'  length  negotiations;  (vii)  the  structure  and
accounting  treatment of the Merger;  (viii) regulatory  aspects of the proposed
transaction; and (ix) the opportunity for Webster shareholders to participate in
a larger financial institution.

PURPOSE AND EFFECTS OF THE MERGER

         The  purpose of the Merger is to enable  Webster to acquire  the assets
and  business of DS Bancor and Derby.  After the  Merger,  certain of Derby's 23
banking  offices will be operated as banking offices of Webster Bank and certain
of such offices will be consolidated with Webster Bank offices.

         The Merger will result in an expansion of Webster's primary market area
to include Derby's banking offices in western New Haven,  eastern  Fairfield and
Hartford Counties in Connecticut.  The assets and business of Derby's 23 banking
offices will broaden Webster's existing  operations in New Haven,  Fairfield and
Hartford  Counties  where  Webster  currently  has 61 banking  offices.  Webster
expects to achieve  reductions  in the current  operating  expenses of DS Bancor
upon the  consolidation  of Derby's  operations  into Webster Bank,  which would
cause the  closing of certain of  Derby's  existing  banking  offices as well as
certain reductions in administrative and support personnel. Upon consummation of
the Merger,  the issued and  outstanding  shares of DS Bancor  Common Stock will
automatically  be  converted  into  Webster  Common  Stock based on the Exchange
Ratio. See "-- Exchange Ratio."

STRUCTURE

         The Merger  will be  effected  by merging  Merger  Sub, a  wholly-owned
subsidiary of Webster  formed to facilitate  the Merger,  into DS Bancor,  which
will then be the Surviving  Corporation.  Immediately  after the consummation of
the Merger, (i) Webster intends that the Surviving  Corporation,  a wholly-owned
subsidiary  of Webster,  will be merged into  Webster,  with  Webster  being the
surviving  holding  company,  and (ii) Derby (which will then be a  wholly-owned
subsidiary of Webster)  will be merged into Webster  Bank.  Webster Bank will be
the federal savings bank resulting from the Bank Merger.

         Upon  consummation of the Merger,  each outstanding  share of DS Bancor
Common  Stock,  except for shares  held as treasury  stock or held,  directly or
indirectly,  by DS Bancor or Webster or any of their  subsidiaries  (other  than
Trust Account Shares or DPC Shares),  will be converted into a certain number of
shares of  Webster  Common  Stock,  plus  cash to be paid in lieu of  fractional
shares. The Merger will not change the outstanding  Webster Common Stock held by
the Webster shareholders.

         DS Bancor and Webster expect that the Merger will be consummated in the
first  quarter  of  1997,  or as soon  as  possible  after  the  receipt  of all
regulatory  and  shareholder  approvals  and the  expiration  of all  regulatory
waiting  periods.  If the Merger is not consummated by June 30, 1997, the Merger
Agreement will be terminated unless DS Bancor and Webster mutually consent to an
extension.

         Notwithstanding  any provision of the Merger Agreement to the contrary,
Webster may elect to modify the structure of the  transactions  contemplated  by
the  Merger  Agreement  as noted  therein  so long as (i) there are no  material
adverse federal income tax consequences to the DS Bancor

                                      -35-



shareholders as a result of such modification, (ii) the consideration to be paid
to DS Bancor  shareholders  under the Merger Agreement is not thereby changed or
reduced in amount,  and (iii) such modification will not be reasonably likely to
zelay  materially or jeopardize  receipt of any required  regulatory  approvals.
Webster presently has no intent to modify the structure.

        In addition,  the Merger Agreement permits Webster to make modifications
to the structure of the Bank Merger.

EXCHANGE RATIO

         The Merger  Agreement  provides that at the Effective Time, each issued
outstanding share of DS Bancor Common Stock (other than shares held, directly or
indirectly, by DS Bancor, Webster or any of their subsidiaries (other than Trust
Account Shares or DPC Shares)) will be converted  automatically into a specified
number of shares of Webster  Common  Stock at the Exchange  Ratio.  The Exchange
Ratio will be determined by dividing  $43.00 by the Base Period  Trading  Price,
computed to five decimal places.  The Exchange Ratio is subject to an adjustment
such that if the Base Period Trading Price is greater than $38.50,  the Exchange
Ratio shall be 1.11688 and if the Base Period Trading Price is less than $31.50,
the Exchange  Ratio shall be 1.36508.  Furthermore,  if the Base Period  Trading
Price is less than $28.00,  the Merger  Agreement may be terminated by DS Bancor
unless  Webster  elects  that the  Exchange  Ratio  shall be equal to the number
resulting  from  dividing  $38.22 by the Base  Period  Trading  Price.  However,
Webster's  seeking of approval  for the  issuance of up to  4,681,658  shares of
Webster  Common  Stock in  connection  with the Merger is based on the number of
shares  which  would be  issued  if the Base  Period  Trading  Price is  $28.00.
Accordingly,  if the Base Period Trading Price is less than $28.00 and DS Bancor
elects to terminate the Merger  Agreement,  Webster cannot increase the Exchange
Ratio as  described  above  without  seeking  further  shareholder  approval and
registering additional shares with the SEC.

         At the Effective  Time,  all shares of treasury stock and all shares of
DS Bancor Common Stock held by Webster,  DS Bancor or any of their  subsidiaries
(other than Trust Account Shares or DPC Shares) shall be canceled.

         The following  table sets forth a range of possible Base Period Trading
Prices of Webster Common Stock, the resultant  Exchange Ratio for each such Base
Period Trading Price, and the equivalent pro forma market value of a share of DS
Bancor Common Stock.

         Based on the $__*__  average of the daily closing  prices per share for
Webster  Common  Stock for the 15  consecutive  trading  days on which shares of
Webster Common Stock were actually traded prior to  ____________  ___, 1996 (the
most   recent   practicable   date  prior  to  the  date  of  this  Joint  Proxy
Statement/Prospectus),  the Exchange Ratio would be ___*___.  Because the market
price of Webster Common Stock is subject to fluctuation,  the Exchange Ratio for
the number of shares of Webster  Common Stock that  holders of DS Bancor  Common
Stock will receive in the Merger may  materially  increase or decrease  prior to
the Merger.  No assurance  can be given as to the Exchange  Ratio at the time of
the Merger.  See "MARKET  PRICES AND  DIVIDENDS."  Such variance would not alter
Webster's or DS Bancor's obligation to consummate the Merger, except as provided
above.  Based on the ____*____  shares of DS Bancor Common Stock  outstanding on
___________ ___, 1996 and an Exchange Ratio of ____*____, Webster would issue up
to ______*______ shares of Webster Common Stock in the Merger, plus cash in lieu
of fractional shares.  These numbers do not reflect additional shares of Webster
Common  Stock to be issued in the event of the  exercise  prior to the Merger of
the _____*_____ existing stock options held by directors, officers and employees
of DS Bancor.

         Certificates  for fractions of shares of Webster  Common Stock will not
be issued. Under the Merger Agreement,  in lieu of a fractional share of Webster
Common Stock,  each holder of DS Bancor Common Stock will be entitled to receive
an amount of cash equal to the  fraction of a share of Webster  Common  Stock to
which such holder would otherwise be entitled multiplied by the average (without
respect  to the  number of shares  traded)  of the high and low sales  prices of
Webster Common Stock,  as reported on The Nasdaq National  Market,  for the five
trading days immediately preceding the fifth trading day before the closing date
of the Merger.  Following  consummation  of the  Merger,  no holder of DS Bancor
Common  Stock would be entitled to any  dividends  or other rights in respect of
any such fraction. The aggregate number of shares of Webster Common Stock, along
with any cash to be paid in lieu of a  fraction  of a share  of  Webster  Common
Stock, payable to each holder of DS Bancor Common Stock, is hereinafter referred
to as the "Purchase Price."

         The  conversion  of DS Bancor Common Stock held by  shareholders  of DS
Bancor  into shares of Webster  Common  Stock at the  Exchange  Ratio will occur
automatically upon the Merger. Pursuant to the Merger Agreement, on or after the
Effective  Time,  Webster will cause the  Exchange  Agent to make payment of the
Purchase Price to each holder of shares of DS Bancor Common Stock who surrenders
the certificate or certificates  representing such shares to the Exchange Agent,
together with a duly executed letter of transmittal.

         The  Exchange  Agent  will  mail a  letter  of  transmittal  as soon as
practicable  after  the  Effective  Time to each  holder  of record of DS Bancor
Common Stock immediately  prior to the Effective Time.  Webster will cause to be
deposited with the Exchange Agent certificates representing the aggregate number
of shares of Webster Common Stock to be issued to DS Bancor shareholders,  along
with the cash to be paid in lieu of fractional  shares. The Exchange Agent shall
not be  obligated,  however,  to deliver or cause to be  delivered  the Purchase
Price to which any holder of DS Bancor Common Stock would  otherwise be entitled
as a result of the Merger  until  such  holder  surrenders  the  certificate  or
certificates representing the shares of DS Bancor Common Stock for exchange, or,
if not  available,  an  appropriate  affidavit of loss and  indemnity  agreement
and/or  a bond  as  may be  required  by  Webster.  Likewise,  no  dividends  or
distributions  with respect to Webster  Common Stock  payable to any such holder
will be paid  until such  holder  surrenders  the  certificate  or  certificates
representing the shares of DS Bancor Common Stock for exchange. No interest will
be paid or accrued to DS  Bancor's  shareholders  on cash in lieu of  fractional
shares or unpaid dividends and distributions, if any.

         If any certificate representing shares of Webster Common Stock is to be
issued  in a name  other  than  that in which the  certificate  for such  shares
surrendered in exchange is registered,  it shall be a condition of such issuance
that the certificate so surrendered shall be properly endorsed

or otherwise be in proper form for transfer and that the person  requesting such
exchange  shall either (i) pay to the Exchange  Agent in advance any transfer or
other taxes  required by reason of the  issuance  of a  certificate  to a person
other  than  the  registered  holder  of the  certificate  surrendered  or  (ii)
establish to the  satisfaction of the Exchange Agent that such tax has been paid
or is not payable.  After the Effective Time, there shall be no transfers on the
stock  transfer  books of DS Bancor of the  shares  of DS  Bancor  Common  Stock
outstanding  immediately  prior  to the  Effective  Time  and  any  such  shares
presented to the Exchange Agent at or after the Effective Time shall be canceled
and exchanged for the Purchase Price.

         ANY PORTION OF THE PURCHASE  PRICE MADE AVAILABLE TO THE EXCHANGE AGENT
THAT  REMAINS  UNCLAIMED  BY DS BANCOR'S  SHAREHOLDERS  FOR 12 MONTHS  AFTER THE
EFFECTIVE TIME WILL BE RETURNED TO WEBSTER. ANY SHAREHOLDER OF DS BANCOR WHO HAS
NOT  EXCHANGED  SHARES  OF DS BANCOR  COMMON  STOCK  FOR THE  PURCHASE  PRICE IN
ACCORDANCE WITH THE MERGER  AGREEMENT  PRIOR TO THAT TIME SHALL  THEREAFTER LOOK
ONLY TO WEBSTER FOR PAYMENT OF THE PURCHASE  PRICE IN RESPECT OF SUCH SHARES AND
ANY UNPAID DIVIDENDS OR DISTRIBUTIONS.  NOTWITHSTANDING  THE FOREGOING,  NONE OF
WEBSTER, DS BANCOR, THE EXCHANGE AGENT OR ANY OTHER PERSON WILL BE LIABLE TO ANY
SHAREHOLDER OF DS BANCOR FOR ANY AMOUNT PROPERLY  DELIVERED TO A PUBLIC OFFICIAL
PURSUANT TO APPLICABLE ABANDONED PROPERTY, ESCHEAT OR SIMILAR LAWS.

         STOCK  CERTIFICATES  FOR SHARES OF DS BANCOR COMMON STOCK SHOULD NOT BE
RETURNED TO DS BANCOR WITH THE PROXY CARD AND SHOULD  ONLY BE  FORWARDED  TO THE
EXCHANGE AGENT AFTER RECEIPT OF THE LETTER OF TRANSMITTAL.

REGULATORY APPROVALS

         Consummation of the Merger is conditioned  upon the receipt of required
regulatory  approvals or waivers from the OTS, the Connecticut  Commissioner and
the Federal Reserve Board.  Applications or waiver requests as to such approvals
have been filed and are pending, or will be filed.

         No other  regulatory  approvals  are  required  to  effect  the  Merger
pursuant to the Merger Agreement.  Neither DS Bancor nor Webster is aware of any
reasons why all required regulatory approvals or waivers should not be obtained.
See "-- Conditions to the Merger."

received    and   is    attached   as   Appendix   A   to   this   Joint   Proxy
Statement/Prospectus).

CONDUCT OF BUSINESS PENDING THE MERGER

         The Merger Agreement contains various restrictions on the operations of
DS  Bancor  and the DS  Bancor  subsidiaries  prior to the  Effective  Time.  In
general,  the Merger Agreement obligates DS Bancor and each DS Bancor subsidiary
to continue  to carry on their  respective  businesses  in the  ordinary  course
consistent with past practices and with prudent banking practices,  with certain
specific limitations on DS Bancor's lending activities and other operations.  DS
Bancor and each DS Bancor subsidiary also are prohibited by the Merger Agreement
from  declaring  any  dividends  on their  capital  stock  other than  specified
dividends on the DS Bancor Common Stock;  splitting,  combining or reclassifying
any of their capital stock;  issuing or authorizing or proposing the issuance of
any securities, other than the issuance of additional shares of DS Bancor Common
Stock upon  exercise  of  certain  existing  stock  options  held by  directors,
officers  and  employees  of DS  Bancor  or  the  Option  held  by  Webster;  or
repurchasing certain specified shares of capital stock. Also, under the terms of
the  Merger  Agreement,  DS Bancor and each DS Bancor  subsidiary  may not amend
their certificates of incorporation or bylaws, nor may they change their methods
of accounting  in effect at December 31, 1995,  except as required by changes in
regulatory or generally accepted accounting principles.  In addition, the Merger
Agreement  restricts  DS Bancor from  increasing  employee  or director  benefit
arrangements  or compensation  other than annual  increases for employees in the
ordinary course consistent with past practices (in the case of Messrs.  DiAdamo,
Santoro and Wells,  not to exceed 6%),  including  the granting of stock options
and entering  into any new  employment  or severance  agreements,  or paying any
bonuses other than to certain specified persons not to exceed a

                                      -39-


specified  aggregate  amount  and  subject  to  such  persons  continuing  their
employment with Webster Bank for a specified period of time.

THIRD PARTY PROPOSALS

         The  Merger  Agreement  provides  generally  that DS Bancor and each DS
Bancor  subsidiary shall not, nor shall DS Bancor authorize or permit any of its
officers, directors, employees or agents, to, solicit, initiate or encourage any
inquiries  relating  to, or the making of, any third  party  takeover  proposal.
There is a similar  prohibition as to any discussion or negotiation of any third
party takeover proposal, or providing third parties with information relating to
such inquiry or proposal,  unless the DS Bancor  Board of  Directors,  following
receipt of written advice of counsel,  reasonably  determines in the exercise of
its fiduciary duty that such discussions or negotiations  should be commenced or
such information must be furnished.

EXPENSES; BREAKUP FEE

         The Merger  Agreement  generally  provides for Webster and DS Bancor to
pay their own expenses relating to the Merger  Agreement,  with an equal sharing
of the costs of  printing  this Joint  Proxy  Statement/Prospectus  and  Webster
paying the SEC filing fees for registering the Webster Common Stock to be issued
in the Merger.  However,  if the Merger Agreement is terminated by Webster or DS
Bancor as a result of a material breach of a representation,  warranty, covenant
or  other  agreement  contained  therein  by  the  other  party,  or if  Webster
terminates  the Merger  Agreement by reason of DS Bancor (i) failing to hold the
DS  Bancor  Meeting  on a  timely  basis;  (ii)  failing  to  recommend  to  its
shareholders approval of the Merger Agreement and the transactions  contemplated
thereby; (iii) failing to oppose any third party takeover proposal (with respect
to (ii) and (iii), unless the DS Bancor Board of Directors, following receipt of
written advice of counsel,  reasonably  determines that such  recommendation  or
opposition,  as  applicable,  would  constitute  a breach of the exercise of its
fiduciary  duty); or (iv) as a result of DS Bancor violating the restrictions on
third party takeover proposals (without regard to the fiduciary duty exception),
the  Merger  Agreement  provides  for  the  non-terminating  party  to  pay  all
reasonable expenses of the terminating party up to $500,000,  plus a breakup fee
of $250,000.  If the Merger  Agreement  is  terminated  by either  Webster or DS
Bancor as a result of the  non-terminating  party failing to obtain the approval
of its shareholders necessary to consummate the Merger, the terminating party is
entitled  to have all of its  reasonable  expenses  up to  $500,000  paid by the
non-terminating  party. Certain events described above that would permit Webster
to terminate the Merger  Agreement  would also constitute  Preliminary  Purchase
Events (as defined) under the Option. See "THE MERGER -- Option Agreement."

OPINION OF DS BANCOR FINANCIAL ADVISOR

         DS Bancor retained Alex. Brown to act as DS Bancor's  financial advisor
in connection with the Merger and related  matters.  Alex. Brown was selected to
act as DS Bancor's  financial advisor based upon its  qualifications,  expertise
and reputation.  Alex. Brown regularly  publishes research reports regarding the
financial  services industry and the businesses and securities of publicly owned
companies in that industry.

         On  October  7,  1996,  at the  meeting  at which the DS  Bancor  Board
approved  and  adopted the Merger  Agreement,  Alex.  Brown  delivered a written
opinion to the DS Bancor Board of Directors  that, as of such date, the Exchange
Ratio  to be  received  by  the  shareholders  of DS  Bancor  was  fair  to  the
shareholders  of DS Bancor from a financial point of view (the  "Opinion").  The
Exchange Ratio will be determined by dividing  $43.00 by the Base Period Trading
Price  computed  to five  decimal  places.  The  Exchange  Ratio is  subject  to
adjustment  such that if the Base Period  Trading  Price is greater than $38.50,
the Exchange Ratio shall be 1.11688 and if the Base Period Trading Price is less
than  $31.50,  the  Exchange  Ratio shall be 1.36508.  Furthermore,  if the Base
Period Trading Price is less than $28.00, the Merger Agreement may be terminated
by DS Bancor unless Webster elects that the Exchange Ratio shall be equal to the
number resulting from dividing

                                      -40-



$38.22 by the Base Period Trading Price.  No limitations  were imposed by the DS
Bancor Board of Directors  upon Alex.  Brown with respect to the  investigations
made or procedures followed by it in rendering the Opinion.

         The full  text of the  Opinion,  which  sets  forth  assumptions  made,
matters  considered and limits on the review  undertaken,  is attached hereto as
Appendix A and is incorporated  herein by reference.  DS Bancor shareholders are
urged to read the Opinion in its entirety.  The following summary of the Opinion
is qualified in its entirety by reference to the full text of the Opinion.

         In  rendering  the  Opinion,   Alex.  Brown  (i)  reviewed  the  Merger
Agreement,   certain  publicly  available  business  and  financial  information
concerning DS Bancor and Webster,  and certain internal  financial  analyses and
forecasts for DS Bancor and Webster  prepared by their  respective  managements;
(ii) held discussions with members of senior management of DS Bancor and Webster
regarding  the past and current  business  operations,  financial  condition and
future prospects of their  organizations;  (iii) reviewed the reported price and
trading  activity  for DS Bancor  Common  Stock  and  Webster  Common  Stock and
compared  certain  financial and stock market  information for each of DS Bancor
and Webster with similar  information for certain other financial  institutions,
the securities of which are publicly  traded;  (iv) reviewed the financial terms
of certain recent business  combinations in the financial  institutions industry
which Alex. Brown deemed  comparable in whole or in part; and (v) performed such
other studies and analyses as Alex. Brown considered appropriate.

         Alex. Brown relied without  independent  verification upon the accuracy
and completeness of all of the financial and other  information  reviewed by and
discussed  with it for  purposes of its Opinion.  With respect to the  financial
forecasts reviewed by Alex. Brown in rendering its Opinion,  Alex. Brown assumed
that such financial  forecasts were reasonably  prepared on bases reflecting the
best currently available  estimates and judgments of the respective  managements
of each of DS Bancor and Webster as to the future  financial  performance  of DS
Bancor  and  Webster.  Alex.  Brown did not make an  independent  evaluation  or
appraisal  of the  assets or  liabilities  of DS Bancor  or  Webster  nor was it
furnished with any such appraisal.

         The  summary  set  forth  below  does  not  purport  to  be a  complete
description  of the  analyses  performed  by  Alex.  Brown in this  regard.  The
preparation of a fairness opinion involves various determinations as to the most
appropriate  and relevant  methods of financial  analysis and the application of
these methods to the particular circumstances and, therefore, such an opinion is
not readily susceptible to summary description. Accordingly, notwithstanding the
separate factors discussed below, Alex. Brown believes that its analyses must be
considered  as a whole and that  selecting  portions of its  analyses and of the
factors  considered by it, without  considering all analyses and factors,  could
create an incomplete view of the evaluation process  underlying its opinion.  No
one of the analyses performed by Alex. Brown was assigned a greater significance
than  any  other.  In  performing  its  analyses,   Alex.  Brown  made  numerous
assumptions  with  respect  to  industry  performance,   business  and  economic
conditions and other matters,  many of which are beyond DS Bancor's or Webster's
control. The analyses performed by Alex. Brown are not necessarily indicative of
actual  values  or  future  results,  which  may be  significantly  more or less
favorable than suggested by such analyses.  Additionally,  analyses  relating to
the values of  businesses  do not  purport to be  appraisals  or to reflect  the
prices at which businesses actually may be sold.

         Analysis  of Selected  Publicly  Traded  Companies.  In  preparing  the
Opinion,  Alex. Brown, using publicly available  information,  compared selected
financial information,  including book value, tangible book value, latest twelve
months ("LTM") earnings, 1996 estimated earnings, 1997 estimated earnings, asset
quality  ratios and loan loss  reserve  levels,  for DS Bancor and several  peer
groups of savings bank organizations.

         The first peer group was  comprised of all savings  banks in the United
States that possessed  asset bases between $1 billion and $5 billion  ("National
Comparables Group"); this peer group was then segmented into those savings banks
headquartered in the Northeast Region (Connecticut,

                                      -41-



Massachusetts,  Maine, New Hampshire,  and Rhode Island) ("Regional  Comparables
Group"). The Regional Comparables Group included Andover Bancorp, Inc. (MA), CFX
Corporation (NH), Eagle Financial Corp. (CT),  Peoples Heritage  Financial Group
(ME), SIS Bancorp,  Inc. (MA), Walden Bancorp,  Inc. (MA) , and Webster (CT). As
of October 4, 1996,  the  relative  multiples  implied by the market price of DS
Bancor's  Common  Stock and the mean  market  price of the  common  stock of the
National Comparables Group and Regional Comparables Group, respectively, to such
selected  financial  data was: to LTM earnings 13.3x for DS Bancor and 13.1x and
12.2x  for the  National  Comparables  Group  and  Regional  Comparables  Group,
respectively;  to 1996 Institutional  Brokerage  Estimation Service  ("I/B/E/S")
estimated  earnings  per share,  12.5x for DS Bancor and 12.2x and 11.5x for the
National Comparables Group and Regional Comparables Group, respectively; to 1997
I/B/E/S  estimated  earnings per share,  11.5x for DS Bancor and 11.1x and 10.9x
for the National Comparables Group and Regional Comparables Group, respectively;
to stated  book  value,  134% for DS Bancor  and 129% and 141% for the  National
Comparables Group and Regional Comparables Group, respectively; to tangible book
value,  138% for DS Bancor and 139% and 163% for the National  Comparables Group
and Regional Comparables Group,  respectively;  and to total assets, 9.0% for DS
Bancor  and  10.7% and 10.8% for the  National  Comparables  Group and  Regional
Comparables Group, respectively.

         Analysis  of  Selected  Acquisition  Transactions.   In  preparing  the
Opinion,   Alex.   Brown  analyzed   certain  selected  merger  and  acquisition
transactions  for savings  banks based upon the  acquisition  price  relative to
stated book value, tangible book value, LTM earnings,  forward one year earnings
(based on I/B/E/S estimates), total assets and the premiums to core deposits and
market price.  The market price premium is measured  against the market price of
the common stock one month prior to the acquisition announcement (in DS Bancor's
case,  September 4, 1996). The analysis  included a review and comparison of the
mean multiples  represented by a sample of recently  effected or pending savings
bank  acquisitions  nationwide  having a  transaction  value  greater  than $100
million which were announced since January 1, 1995 (a total of 31 transactions),
("National  Transactions"),  as segmented  into: (i)  transactions  in which the
selling savings bank was  headquartered  in the Northeast Region (10) ("Regional
Transactions")  and (ii) transactions in which the selling savings bank achieved
a return on average assets ("ROAA") less than 0.80% in the year of its announced
acquisition   (13)   ("Profitability-Segmented   Transactions").   DS   Bancor's
annualized ROAA was 0.74% for the 6 months ended June 30, 1996.

         The relative  multiples  implied by the Exchange Ratio ($43.00  implied
per share value to DS Bancor shareholders as of October 7, 1996) and each of the
selected acquisition transaction  segmentations,  respectively,  are provided in
the following table:

         Contribution Analysis.  Alex. Brown also determined the contribution by
DS Bancor of key  historical  balance  sheet  items  (including  assets,  loans,
deposits,  stated  equity and  tangible  equity)  and  selected  historical  and
estimated  income  statement items  (including  latest twelve months net income,
1996 I/B/E/S  estimated  earnings and 1997  I/B/E/S  estimated  earnings) to the
resulting pro forma entity,  as compared to the ownership  percentage of the pro
forma entity's common stock that was received by current DS Bancor  shareholders
in aggregate as a result of the acquisition (as of the Exchange Ratio on October
4, 1996).

         The  relative  levels of  contribution  by DS Bancor in these  selected
areas  and the  level of pro  forma  ownership  received  by  current  DS Bancor
shareholders in aggregate are presented in the following table:

         Impact on DS Bancor  Shareholders.  Based on the  Exchange  Ratio as of
October 4, 1996,  Alex.  Brown determined the expected effect of the transaction
to the current  holders of DS Bancor Common Stock as described  below:  On a pro
forma  basis,  LTM  earnings  per current DS Bancor  Common Stock share would be
$2.79,  a 1.5% decline from DS Bancor's stand alone earnings per share of $2.83.
Book value per share on a pro forma  basis would be $27.98 per current DS Bancor
Common Stock share,  which  represents a 7.0%  increase  from DS Bancor's  stand
alone  fully-diluted  book value of $26.14.  Dividends per share would  increase
230.0%  from DS Bancor's  stand  alone  dividend of $0.24 per share to $0.79 per
current DS Bancor Common Stock share on a pro forma basis.

         These pro forma values and their  resulting  implications to current DS
Bancor  shareholders  are based on historical  Webster  financials and DS Bancor
financials and do not reflect any adjustments  (expense savings or restructuring
costs)  relating  to the  Merger.  As such the  values  discussed  above are not
necessarily indicative of actual values, which may be significantly more or less
than such estimates.

         Discounted  Dividend  Analysis.  Using  discounted  cash flow analysis,
Alex.  Brown estimated the present value of the future dividend  streams that DS
Bancor could produce over a five year period, under different  assumptions as to
dividend payout ratios,  if DS Bancor performed in accordance with  management's
forecasts and certain variants thereof.  Alex. Brown also estimated the terminal
value for DS  Bancor's  common  equity  after the five year  period by  applying
earnings  acquisition  multiples (14.5 - 16.0 times) currently being received by
savings  bank  institutions  with similar  profitability  ratios as DS Bancor is
projected to have during its calendar year ended December 31, 2000. The range of
multiples  used  reflected  a variety  of  scenarios  regarding  the  growth and
profitability  prospects of DS Bancor.  The dividend streams and terminal values
were

                                      -43-



then  discounted to present  values using  discount  rates ranging from 14.0% to
15.0%,  which reflect  different  assumptions  regarding  the required  rates of
return of holders or prospective buyers of DS Bancor's common equity.

         Compensation  of  Financial  Advisor.  Pursuant  to  the  terms  of  an
engagement letter dated March 22, 1996, DS Bancor is required to pay Alex. Brown
a fee of $100,000 for acting as financial advisor in connection with the Merger,
including rendering the Opinion. In addition,  DS Bancor has agreed to pay Alex.
Brown an additional fee of $750,000,  plus expenses,  upon  consummation  of the
Merger.  Whether or not the Merger is consummated,  DS Bancor also has agreed to
indemnify Alex.  Brown and certain  related persons against certain  liabilities
relating to or arising out of its engagement.

OPINION OF WEBSTER FINANCIAL ADVISOR

         Webster engaged Merrill Lynch to act as its exclusive financial advisor
in connection with the Merger. Pursuant to the terms of its engagement,  Merrill
Lynch  agreed to assist  Webster  in  analyzing,  structuring,  negotiating  and
effecting an acquisition  transaction  with DS Bancor.  Webster selected Merrill
Lynch because Merrill Lynch is a nationally  recognized  investment banking firm
with  substantial  experience  in  transactions  similar  to the  Merger  and is
familiar  with  Webster  and its  business.  As part of its  investment  banking
business,  Merrill Lynch is  continually  engaged in the valuation of businesses
and their securities in connection with mergers and acquisitions.

         As part of its  engagement,  representatives  of Merrill Lynch attended
the  meeting of the  Webster  Board held on October 6, 1996 at which the Webster
Board  considered  the Merger  Agreement.  On October  6,  1996,  Merrill  Lynch
rendered its written  opinion to the effect that, as of such date,  the Exchange
Ratio (see "-- Exchange  Ratio")  pursuant to the Merger  Agreement  was fair to
Webster from a financial  point of view. Such opinion was reconfirmed in writing
as of the date of the Joint Proxy Statement/Prospectus.

         The full text of Merrill  Lynch's  written opinion dated as of the date
of the Joint Proxy  Statement/Prospectus is attached as Appendix B to this Joint
Proxy   Statement/Prospectus  and  is  incorporated  herein  by  reference.  The
description  of the opinion set forth  herein is  qualified  in its  entirety by
reference to Appendix B. Webster  shareholders  are urged to read the opinion in
its entirety for a description of the  procedures  followed,  assumptions  made,
matters considered, and qualifications and limitations on the view undertaken by
Merrill Lynch in connection therewith.

         MERRILL  LYNCH'S OPINION IS DIRECTED TO THE WEBSTER BOARD AND ADDRESSES
ONLY THE EXCHANGE RATIO. IT DOES NOT ADDRESS THE UNDERLYING BUSINESS DECISION TO
PROCEED WITH THE MERGER AND DOES NOT CONSTITUTE, NOR SHALL IT BE CONSTRUED AS, A
RECOMMENDATION TO ANY WEBSTER SHAREHOLDER AS TO HOW SUCH SHAREHOLDER SHOULD VOTE
AT THE WEBSTER MEETING OR ANY OTHER MATTER IN CONNECTION THEREWITH.

         Merrill  Lynch has  informed  Webster  that in  arriving at its written
opinion,  Merrill  Lynch,  among other  things:  (i) reviewed  Webster's  Annual
Reports  to  Shareholders,  Annual  Reports on Form 10-K and  related  financial
information  for the three  fiscal years ended  December 31, 1995 and  Webster's
Quarterly Reports on Form 10-Q and related unaudited  financial  information for
each of the three months ended June 30,1996 and March 31, 1996; (ii) reviewed DS
Bancor's Annual Reports to Shareholders, Annual Reports on Form 10-K and related
financial  information for the three fiscal years ended December 31, 1995 and DS
Bancor's  Quarterly  Reports  on  Form  10-Q  and  related  unaudited  financial
information for each of the three months ended June 30, 1996 and March 31, 1996;
(iii) reviewed certain limited financial  information  relating to the financial
condition,  businesses,  earnings, assets and prospects of Webster and DS Bancor
relating to the future  financial  performance of Webster  following the Merger,
including financial  forecasts and assumptions  regarding projected cost savings
resulting from the Merger, furnished to it by senior

                                      -44-


management  of  Webster  and  of  DS  Bancor;  (iv)  conducted  certain  limited
discussions  with  members  of senior  management  of  Webster  and of DS Bancor
concerning the respective financial condition,  businesses, earnings, assets and
prospects of Webster and DS Bancor and their  respective  views as to the future
financial performance of Webster, DS Bancor and the combined entity, as the case
may be,  following  the Merger;  (v) reviewed the  historical  market prices and
trading  activity for DS Bancor's common shares and Webster's  common shares and
compared them,  respectively,  with those of certain  publicly traded  companies
which it  deemed  to be  relevant;  (vi)  compared  the  respective  results  of
operations  of  Webster  and DS Bancor  with those of  certain  publicly  traded
companies which it deemed to be relevant;  (vii) compared the financial terms of
the Merger  contemplated  by the Merger  Agreement  with the financial  terms of
certain other mergers and  acquisitions  which it deemed to be relevant;  (viii)
reviewed the amount and timing of the  projected  cost savings for DS Bancor and
Webster  following  the  Merger as  prepared, and  discussed  with it, by senior
management  of Webster;  (ix)  considered,  based upon  information  provided by
Webster's  senior  management,  the pro forma effects of the Merger on Webster's
capitalization  ratios and projected earnings,  book and tangible book value per
share; (x) reviewed the Merger Agreement; and (xi) reviewed such other financial
studies and  analyses  and  performed  such other  investigations  and took into
account such other matters as it deemed necessary.

         In preparing  its opinion,  Merrill  Lynch  assumed and relied upon the
accuracy and  completeness  of all financial and other  information  supplied or
otherwise  made  available to it for purposes of its opinion,  and Merrill Lynch
has not  independently  verified such  information  or undertaken an independent
evaluation or appraisal of the assets or liabilities of Webster or DS Bancor nor
has it been furnished any such evaluation or appraisal.  Merrill Lynch is not an
expert in the  evaluation of allowance  for loan losses,  and it has not made an
independent  evaluation  of the  adequacy of the  allowances  for loan losses of
Webster or DS Bancor nor has it reviewed any individual credit files, and it has
assumed that the  aggregate  allowance  for loan losses of Webster and DS Bancor
are  adequate to cover such losses and will be adequate on a pro forma basis for
the combined  entity.  Merrill Lynch has also assumed and relied upon the senior
management  of  Webster  referred  to  above  as  to  the   reasonableness   and
achievability of the financial and operating  forecasts furnished by Webster and
DS Bancor (and the assumptions  and bases  therefore).  In that regard,  Merrill
Lynch has assumed  with  Webster's  consent  that such  information,  including,
without  limitation,  financial  forecasts,  projected  cost savings,  operating
synergies and after-tax  merger and  reorganization  charges  resulting from the
Merger and projections  regarding  underperforming and nonperforming assets, net
charge-offs,  and adequacy of  reserves,  reflect the best  currently  available
estimates  and judgment of the senior  management of Webster and DS Bancor as to
the  expected  future  financial  performance  of  Webster,  DS Bancor,  and the
combined  entity,  as the case may be. Merrill  Lynch's  opinion was necessarily
based on  economic,  market  and  other  conditions  as in  effect  on,  and the
information made available to it as of, the date of its opinion.

         Merrill  Lynch's  opinion  has  been  rendered  without  regard  to the
necessity  for,  or level of, any  restrictions,  obligations,  undertakings  or
divestitures  which may be  imposed  or  required  in the  course  of  obtaining
regulatory approvals for the Merger.

         In connection with rendering its opinion dated October 6, 1996, Merrill
Lynch performed a variety of financial analyses,  consisting of those summarized
below. The summary set forth below does not purport to be a complete description
of the analyses performed by Merrill Lynch in this regard, although it describes
the material  terms of the analyses  performed.  The  preparation  of a fairness
opinion involves various  determinations as to the most appropriate and relevant
methods  of  financial  analysis  and the  application  of these  methods to the
particular  circumstances  and,  therefore,  such  an  opinion  is  not  readily
susceptible  to  a  partial  analysis  or  summary   description.   Accordingly,
notwithstanding  the separate factors  summarized below,  Merrill Lynch believes
that its analyses must be considered as a whole and that  selecting  portions of
its analyses and factors considered by it, without  considering all analyses and
factors,  or attempting to ascribe relative weights to some or all such analyses
and  factors,  could  create  an  incomplete  view  of  the  evaluation  process
underlying Merrill Lynch's opinion. In addition, while Merrill Lynch gave

                                      -45-


the various  analyses  approximately  similar weight,  it may have used them for
different purposes and may have deemed various assumptions more or less probable
than other  assumptions,  so that the ranges of  valuations  resulting  from any
particular  analysis  described  below should not be taken to be Merrill Lynch's
view of the actual  value of Webster and DS Bancor.  The fact that any  specific
analysis has been referred to in the summary below is not meant to indicate that
such analysis was given more weight than any other analysis.

         In  performing  its analyses,  Merrill Lynch made numerous  assumptions
with respect to industry  performance,  general business and economic conditions
and other  matters,  many of which are  beyond the  control  of  Webster  and DS
Bancor. The analyses  performed by Merrill Lynch are not necessarily  indicative
of actual  values or future  results,  which may be  significantly  more or less
favorable than suggested by such analyses. Such analyses were prepared solely as
part of Merrill  Lynch's  analysis of the  fairness  to Webster of the  Exchange
Ratio and were provided to the Webster Board in connection  with the delivery of
Merrill Lynch's  opinion.  With respect to the comparison of selected  companies
analysis  and the analysis of selected  thrift  merger  transactions  summarized
below, no public company  utilized as a comparison is identical to Webster or DS
Bancor  and  such  analyses  necessarily  involve  complex   considerations  and
judgments concerning the differences in financial and operating  characteristics
of the companies and other factors that could affect the public  trading  values
of the  companies  concerned.  The analyses  performed by Merrill  Lynch are not
necessarily  indicative  of  actual  values  or  future  results,  which  may be
significantly  more or less  favorable  than  suggested  by such  analyses.  The
analyses  do not purport to be  appraisals  or to reflect the prices at which DS
Bancor might actually be sold or the prices at which any securities may trade at
the present time or at any time in the future. In addition,  as described above,
Merrill Lynch's opinion is just one of many factors taken into  consideration by
the Webster  Board of  Directors.  See "--  Recommendation  of Webster  Board of
Directors and Reasons for the Issuance."

         The projections furnished to Merrill Lynch and used by it in certain of
its analyses  were  prepared by the senior  management of Webster and DS Bancor.
Webster does not publicly disclose internal  management  projections of the type
provided to Merrill Lynch in connection with its review of the Merger,  and as a
result,   such  projections  were  not  prepared  with  a  view  towards  public
disclosure.  The  projections  were based on numerous  variables and assumptions
which are inherently uncertain,  including, without limitation,  factors related
to general economic and competitive conditions, and accordingly,  actual results
could vary significantly from those set forth in such projections.

         The  following  is a summary  of the  material  analyses  presented  by
Merrill  Lynch to the  Webster  Board on  October  6, 1996 (the  "Merrill  Lynch
Report") in connection with its October 6, 1996 opinion.

         Summary of Proposal.  Merrill Lynch  reviewed the terms of the proposed
transaction,  including the Exchange Ratio and the aggregate  transaction value.
Merrill Lynch  reviewed the implied  value of the Exchange  Ratio based upon the
closing  share price of Webster  Common Stock on October 1, 1996.  This analysis
showed that the implied value of the Exchange Ratio was approximately $43.00 per
share of DS Bancor  Common  Stock,  for a total  value of  approximately  $136.6
million  (including  the book  value of DS  Bancor  shares  held by  Webster  on
September 30,  1996).  Based on the  aggregate  consideration  offered using the
October 1, 1996 price for Webster  Common Stock,  Merrill Lynch  calculated  the
price to market,  price to book,  price to tangible  book, and price to earnings
multiples,  and the implied  deposit  premium paid  (defined as the  transaction
value  minus  the  tangible  book  value  divided  by  total  deposits)  in  the
contemplated  transaction.  This analysis  yielded a price to market multiple of
1.14x,  a price to book value  multiple of 1.62x, a price to tangible book value
multiple of 1.67x, a price to earnings  multiple of 14.12x (based on DS Bancor's
earnings for the three months  ended June 30, 1996  annualized),  and an implied
deposit premium of 5.33%.

         Pro Forma Merger  Analysis.  Merrill Lynch  analyzed  certain pro forma
effects resulting from the Merger. Merrill Lynch analyzed three Exchange Ratios,
1.11688,  1.22857 and 1.36508,  based on Base Period  Trading  Prices of $38.50,
$35.00 and $31.50, respectively,  representing the range of Exchange Ratios (see
"-- Exchange  Ratio").  This analysis  indicated  that at a Base Period  Trading
Price of $31.50  the  transaction  would  result  in an  increase  in  projected
earnings per Webster Common Stock  equivalent  share and a decrease in projected
book value per Webster Common Stock equivalent share and tangible book value per
Webster  Common Stock  equivalent  share,  and at Base Period  Trading Prices of
$35.00 and $38.50, the transaction would result in an

                                      -46-



increase in projected  earnings per Webster  Common Stock  equivalent  share and
tangible book value per Webster Common Stock  equivalent share and a decrease in
projected  book  value  per  Webster  Common  Stock  equivalent  share.  In this
analysis,  Merrill Lynch assumed that DS Bancor performed in accordance with the
earnings forecast provided to Merrill Lynch by Webster senior management,  which
included  projected  cost  savings  and  earning  enhancement   assumptions  and
after-tax merger and reorganization charge assumptions.

         Discounted Dividend Stream Analysis. Using a discounted dividend stream
analysis,  Merrill Lynch  estimated  the present value of the future  streams of
after tax cash flows that DS Bancor could  produce on a  stand-alone  basis from
1997 through 2001 and distribute to shareholders ("dividendable net income"). In
this analysis, Merrill Lynch assumed that DS Bancor performed in accordance with
the earnings forecasts,  including projected cost savings, earnings enhancements
and  after-tax  merger and  reorganization  charges  resulting  from the Merger,
provided to Merrill Lynch by Webster's  senior  management  and that DS Bancor's
tangible common equity to tangible asset ratios would be maintained at a minimum
5.00% level.  Merrill  Lynch  estimated  the  terminal  values for the DS Bancor
Common Stock at 8.0,  9.0 and 10.0 times DS Bancor's  2002  estimated  operating
income (defined as net income before intangible amortization).  The dividendable
net income  streams and terminal  values were then  discounted to present values
using  different  discount  rates  (ranging  form 13% to 15%)  chosen to reflect
different  assumptions  regarding  the  required  rates of return of  holders or
prospective  buyers of Webster Common Stock.  This  discounted  dividend  stream
analysis  indicated a reference range of between $38.71 and $48.40 per share for
DS Bancor Common Stock. The analysis was based upon Webster senior  management's
projections,  which were based upon many factors and assumptions,  many of which
are beyond the  control of Webster  and DS  Bancor.  As  indicated  above,  this
analysis is not  necessarily  indicative of actual values or future  results and
does not purport to reflect the prices at which any  securities may trade at the
present or at any time in the future.  Merrill  Lynch noted that the  discounted
dividend  stream  analysis  was included  because it is a widely used  valuation
methodology, but noted that the results of such methodology are highly dependent
upon the  numerous  assumptions  that must be made,  including  earnings  growth
rates, dividend payout rates, terminal values and discount rates.

         Merrill Lynch also estimated the present value of the  dividendable net
income that Webster could produce on a stand-alone basis from 1997 through 2001.
In this  analysis,  Merrill Lynch  assumed that Webster  performed in accordance
with the  earnings  forecasts  provided  to Merrill  Lynch by  Webster's  senior
management  and  projected  the maximum  dividends  that would permit  Webster's
tangible  common  equity to tangible  asset ratio to be  maintained at a minimum
level of 4.44%,  equal to Webster's  projected tangible equity to tangible asset
ratio at December 31, 1996.  Merrill  Lynch  estimated  the terminal  values for
Webster Common Stock at 9.0x and 10.0x  Webster's year 2002 estimated  operating
income. The dividendable income streams and terminal values were then discounted
to present values using a discount rate of 14%. This discounted  dividend stream
analysis  indicated a reference  range of between $31.97 and $34.24 per share of
Webster Common Stock.  The analysis was based upon Webster's  senior  management
projections,  which were based upon many factors and assumptions,  many of which
are beyond the control of Webster.  As indicated  above,  this  analysis did not
purport to be indicative of actual future results and did not purport to reflect
the prices at which shares of Webster Common Stock may trade before or after the
Merger.

         Finally,  Merrill Lynch estimated the present value of the dividendable
net income that the combined  institution  could produce from 1997 through 2001.
In this analysis,  Merrill Lynch assumed that the combined institution performed
in accordance with the earnings forecasts provided to Merrill Lynch by Webster's
senior  management  and  projected the maximum  dividends  that would permit the
combined  institution's  tangible  common  equity to tangible  asset ratio to be
maintained  at a minimum  level of 4.82%,  equal to the  combined  institution's
projected  tangible equity to tangible asset ratio at December 31, 1996. Merrill
Lynch estimated the terminal values for the combined  institution's common stock
at 9.0x and 10.0x the  combined  institution's  year  2002  estimated  operating
income. The dividendable income streams and terminal values were then discounted
to present  values using a discount  rate of 14%.  Assuming the  projected  cost
savings

                                      -47-



resulting  from the Merger as  provided  to Merrill  Lynch by  Webster's  senior
management and after-tax  merger and  reorganization  charges,  this  discounted
dividend  stream  analysis  indicated  a reference  range of between  $32.38 and
$34.69 per share of Webster Common Stock,  assuming an Exchange Ratio of 1.36508
based on a Base Period  Trading  Price of $31.50,  a reference  range of between
$33.35 and $35.73 per share of Webster Common Stock,  assuming an Exchange Ratio
of 1.22857 based on a Base Period Trading Price of $35.00, and a reference range
of between  $34.18 and $36.62 per share of Webster  Common  Stock,  assuming  an
Exchange  Ratio of 1.11688 based on a Base Period  Trading Price of $38.50.  The
analysis was based upon Webster's and DS Bancor's senior management projections,
which were based upon many factors and assumptions, many of which are beyond the
control of Webster and DS Bancor.  As  indicated  above,  this  analysis did not
purport to be indicative of actual future results and did not purport to reflect
the prices at which shares of Webster Common Stock may trade before or after the
Merger.

         Analysis of Selected Thrift Merger Transactions. Merrill Lynch reviewed
publicly available  information  regarding nationwide thrift merger transactions
with a value greater than $75 million which had occurred  since January 1, 1995.
Merrill  Lynch  compared  the price to  market,  price to book  value,  price to
tangible book value,  price to earnings and the implied  deposit premium paid in
the contemplated transaction and such selected thrift merger transactions.  This
analysis yielded a range of price to market multiples of approximately  0.97x to
1.63x with a mean of 1.28x and a median of 1.26x  (compared  with a  transaction
multiple  of 1.14x for DS Bancor  using the  October 1, 1996  price for  Webster
Common Stock), a range of price to book value multiples of  approximately  0.97x
to 2.52x with a mean of 1.62x and a median of 1.63x (compared with a transaction
multiple  of 1.62x for DS Bancor  using the  October 1, 1996  price for  Webster
Common  Stock),   a  range  of  price  to  tangible  book  value   multiples  of
approximately  1.08x  to  2.64x  with a mean of  1.68x  and a  median  of  1.69x
(compared  with a transaction  multiple of 1.67x for DS Bancor using the October
1, 1996 price for Webster Common Stock), a range of price to earnings  multiples
of  approximately  7.01x to 24.69x  with a mean of 15.76x and a median of 15.08x
(compared with a transaction  multiple of 14.12x for DS Bancor using the October
1, 1996 price for Webster Common Stock and annualized earnings for DS Bancor for
the three months ended June 30,  1996), and a range of implied deposit  premiums
paid of approximately 2.80% to 19.02% with a mean of 8.27% and a median of 7.25%
(compared with an implied  transaction  premium of 5.33% for DS Bancor using the
October  1, 1996 price for  Webster  Common  Stock).  This  analysis  yielded an
overall imputed reference range per share of DS Bancor Common Stock of $19.77 to
$87.03, and $42.53 to $52.30 based in the mean and median imputed range.

         Merrill Lynch also reviewed publicly  available  information  regarding
New England  thrift  merger  transactions  with a value greater than $20 million
which had occurred  since January 1, 1995.  Merrill Lynch  compared the price to
market, price to book value, price to tangible book value, price to earnings and
the implied  deposit  premium paid,  in the  contemplated  transaction  and such
selected thrift merger  transactions.  This analysis yielded a range of price to
market  multiples  of  approximately  0.90x to 1.60x  with a mean of 1.33x and a
median of 1.40x  (compared  with a  transaction  multiple of 1.14x for DS Bancor
using the October 1, 1996 price for Webster Common  Stock),  a range of price to
book value multiples of approximately  0.94x to 1.86x with a mean of 1.62x and a
median of 1.63x  (compared  with a  transaction  multiple of 1.62x for DS Bancor
using the October 1, 1996 price for Webster Common  Stock),  a range of price to
tangible  book value  multiples of  approximately  0.96x to 1.86x with a mean of
1.60x and a median of 1.66x  (compared with a transaction  multiple of 1.67x for
DS Bancor using the October 1, 1996 price for Webster Common Stock),  a range of
price to  earnings  multiples  of  approximately  8.72x to 17.87x with a mean of
13.70x and a median of 13.04x  (compared  with a transaction  multiple of 14.12x
for DS Bancor  using the  October 1, 1996  price for  Webster  Common  Stock and
annualized earnings for DS Bancor for the three months ended June 30, 1996), and
a range of implied deposit premiums paid of approximately  3.33% to 8.30% with a
mean of  5.85%  and a median  of 5.77%  (compared  with an  implied  transaction
premium  of 5.33% for DS Bancor  using the  October  1, 1996  price for  Webster
Common Stock).  This analysis  yielded an overall  imputed  reference  range per
share of DS Bancor Common Stock of $31.97 to $60.40,  and $37.93 to $54.36 based
on the mean and median imputed range.

                                      -48-


         Merrill Lynch also reviewed publicly  available  information  regarding
Connecticut  thrift  merger  transactions  with a value greater than $20 million
which had occurred  since January 1, 1994.  Merrill Lynch  compared the price to
market, price to book value, price to tangible book value, price to earnings and
the implied price to deposit premium paid, in the  contemplated  transaction and
such selected thrift merger transactions. This analysis yielded a range of price
to market multiples of  approximately  1.29x to 1.60x with a mean of 1.45x and a
median of 1.46x  (compared  with a  transaction  multiple of 1.14x for DS Bancor
using the October 1, 1996 price for Webster Common  Stock),  a range of price to
book value multiples of approximately  1.62x to 1.86x with a mean of 1.76x and a
median of 1.77x  (compared  with a  transaction  multiple of 1.62x for DS Bancor
using the October 1, 1996 price for Webster Common  Stock),  a range of price to
tangible  book value  multiples of  approximately  1.62x to 1.86x with a mean of
1.79x and a median of 1.83x  (compared with a transaction  multiple of 1.67x for
DS Bancor using the October 1, 1996 price for Webster Common Stock),  a range of
price to earnings  multiples  of  approximately  13.86x to 16.60x with a mean of
15.23x and a median of 15.23x  (compared  with a transaction  multiple of 14.12x
for DS Bancor  using the  October 1 1996  price  for  Webster  Common  Stock and
annualized earnings for DS Bancor for the three months ended June 30, 1996), and
a range of implied deposit premiums paid of approximately  4.43% to 6.36% with a
mean of  5.09%  and a median  of 4.78%  (compared  with an  implied  transaction
premium  of 5.33% for DS Bancor  using the  October  1, 1996  price for  Webster
Common Stock).  This analysis yielded overall imputed reference ranges per share
of DS Bancor Common Stock of $39.09 to $60.40, and $41.01 to $54.93 based on the
mean and median imputed range.

         No company or transaction used in the above analysis as a comparison is
identical to Webster, DS Bancor or the contemplated transaction. Accordingly, an
analysis  of  the  results  of  the  foregoing   necessarily   involves  complex
considerations and judgments  concerning  differences in financial and operating
characteristics  of the companies and other factors that could affect the public
trading  value of the companies to which they are being  compared.  Mathematical
analysis  (such  as  determining  the  mean or  median)  is not,  in  itself,  a
meaningful method of using comparable data.

         Comparison of Selected Companies.  In connection with the Merrill Lynch
Report, Merrill Lynch compared selected operating and stock market results of DS
Bancor to the publicly available corresponding data of Webster and certain other
companies  which Merrill Lynch deemed to be relevant,  including Dime Financial,
Eagle   Financial,   Peoples  Savings  Bank  of  New  Britain  and  SIS  Bancorp
(collectively the "DS Bancor  Composite").  This comparison showed,  among other
things, that (i) as of September 30, 1996, the ratio of DS Bancor's market price
to fully  taxed core  earnings  for the twelve  months  ended June 30,  1996 was
13.12x,  compared  to a mean of 13.26x for the DS Bancor  Composite,  (ii) as of
September  30,  1996,  the ratio of DS Bancor's  market  price to book value per

of DS Bancor's  market price to  estimated  earnings for the twelve month period
ending December 31, 1997 was 11.64x,  compared to a mean of 10.02x for DS Bancor
Composite  (assuming  I/B/E/S  earnings  estimates for both DS Bancor and the DS
Bancor  Composite),  (v) for the twelve month  period  ended June 30,  1996,  DS
Bancor's  return on average assets was 0.72% compared to a mean of 0.81% for the
DS Bancor Composite, (vi) for the twelve month period ended June 30,1996, the DS
Bancor's  return on average  equity was 10.98%  compared to a mean of 10.56% for
the DS  Bancor  Composite,  (vii)  at  June  30,  1996,  DS  Bancor's  ratio  of
nonperforming loans to total loans was 2.12% compared to a mean of 1.39% for the
DS Bancor Composite, and (viii) at June 30, 1996, DS Bancor's ratio of loan loss
reserves to  nonperforming  assets was 35.13%  compared to a mean of 114.89% for
the DS Bancor Composite.

         Merrill Lynch also compared selected operating and stock market results
of  Webster  to the  publicly  available  corresponding  data of  certain  other
companies which Merrill Lynch deemed to be relevant, including ALBANK Financial,
Andover Bancorp, Eagle Financial, Peoples Heritage Financial, RCSB Financial and
SIS Bancorp  (collectively  the "Webster  Composite").  This

                                      -49-



comparison  showed,  among other things,  that (i) as of September 30, 1996, the
ratio of Webster's market price to earnings for the twelve months ended June 30,
1996 was 14.04x, compared to a mean of 12.07x for the Webster Composite, (ii) as
of  September  30, 1996,  the ratio of Webster's  market price to book value per
share at June 30,  1996 was 1.44 x,  compared to a mean of 1.32x for the Webster
Composite,  (iii) as of September 30, 1996, the ratio of Webster's  market price

ratio of  Webster's  market  price to  estimated  earnings  for the twelve month
period ending December 31, 1997 was 10.28x, compared to a mean of 10.06x for the
Webster Composite  (assuming I/B/E/S earnings estimates for both Webster and the
Webster  Composite),  (v) for the  twelve  month  period  ended  June 30,  1996,
Webster's return on average assets was 0.60% compared to a mean of 0.91% for the
Webster  Composite,  (vi) for the  twelve  month  period  ended  June 30,  1996,
Webster's  return on average equity was 10.69%  compared to a mean of 10.86% for
the Webster Composite,  (vii) at June 30, 1996, Webster's ratio of nonperforming
loans to total  loans was  1.51%  compared  to a mean of 1.35%  for the  Webster
Composite, and (viii) at June 30, 1996, Webster's ratio of loan loss reserves to
nonperforming  assets was 82.08%  compared  to a mean of 99.20% for the  Webster
Composite.

         Mark-to-Market  Analysis.  Merrill Lynch evaluated the estimated market
value of key  components of DS Bancor's  balance sheet,  including,  among other
things,  DS  Bancor's  investment  securities  and  mortgage-backed   securities
portfolios, loan portfolio and premises and equipment. This analysis indicated a
valuation of approximately  $41.18 to $47.63 per share of DS Bancor Common Stock
(on a fully diluted basis) based on a range of implied  deposit premium of 4% to
6%, before any credit quality related to the portfolios was analyzed.

         In connection with its opinion dated as of the date of this Joint Proxy
Statement/Prospectus,   Merrill   Lynch   performed   procedures  to  update  as
appropriate  certain of the analyses  described above and review the assumptions
on which such  analyses  were based and the  factors  considered  in  connection
therewith.  Merrill  Lynch did not  perform  any  analyses  in addition to those
described above in updating its October 6, 1996 opinion.

         Merrill Lynch has been retained by the Board of Directors of Webster as
an independent contractor to act as financial adviser to Webster with respect to
the Merger.  Merrill Lynch is a nationally  recognized  investment  banking firm
which, among other things,  regularly engages in the valuation of businesses and
securities,  including  banking  institutions,  in  connection  with mergers and
acquisitions.  In  addition,  within the past  three  years,  Merrill  Lynch has
provided  financial  advisory,  investment banking and other services to Webster
and has  received  customary  fees for the  rendering of such  services.  In the
ordinary  course of business,  Merrill  Lynch and its  affiliates  may trade the
securities  of DS Bancor or Webster for its own accounts and the accounts of its
customers, and accordingly,  may from time to time hold a long or short position
in such securities.

         Merrill  Lynch  will  receive  a fee for  investment  banking  services
related to the Merger and related advisory work of $650,000.  Merrill Lynch will
also be  reimbursed  for  its  reasonable  out-of-pocket  expenses  incurred  in
connection   with  its  advisory  work,   including  the  reasonable   fees  and
disbursements  of its legal  counsel,  and will be indemnified  against  certain
liabilities  related  to or arising  out of the  Merger,  including  liabilities
arising under the securities laws.

(provided the terminating  party is not in violation of the Merger Agreement) as
summarized below:

                      (i)  by mutual written consent of Webster and DS Bancor;

                      (ii) by Webster  or  DS  Bancor  if  (a) 30 days after any
required regulatory approval is denied or regulatory application is withdrawn at
a regulator's request,  unless action is timely taken for a rehearing or to file
an amended  application;  (b) the Merger has not  occurred on or before June 30,

                      (iii) by  Webster,  in  the  event  of  a  breach  of  any
representation,   warranty,  covenant  or  agreement  contained  in  the  Merger
Agreement by DS Bancor, if such breach or breaches would have a material adverse
effect on DS Bancor;

                      (iv) by DS  Bancor,  in the  event  of a  breach  of any
representation,   warranty,  covenant  or  agreement  contained  in  the  Merger
Agreement by Webster,  if such breach or breaches would have a material  adverse
effect on Webster;

                      (v)  by  Webster,  if DS Bancor or its Board of  Directors
(a)  fails  to hold  the DS  Bancor  Meeting  on a timely  basis;  (b)  fails to
recommend to DS Bancor's  shareholders  the approval of the Merger Agreement and
the  transactions  contemplated  thereby;  (c) fails to oppose  any third  party

constitute  a  breach  of the  Board of  Directors'  fiduciary  duties);  or (d)
violates the covenant  relating to third party proposals  (without regard to the
fiduciary duty exception); and

                      (vi) by DS Bancor,  if the Base  Period  Trading  Price is
less than $28.00 unless Webster elects that the Exchange Ratio shall be equal to
the number resulting from dividing $38.22 by the Base Period Trading Price.

         The Merger  Agreement also provides that subject to applicable law, the
Board of Directors of the parties may (i) amend the Merger Agreement  (except as

no amendment of the Merger Agreement may be made without further

                                      -51-



shareholder  approval,  if the  amendment  would reduce the amount or change the
form of the  consideration to be delivered to the DS Bancor  shareholders  under
the Merger Agreement.

CERTAIN FEDERAL INCOME TAX CONSEQUENCES

         The  following  summary  discusses  the  principal  federal  income tax
consequences  of the  Merger.  The  summary is based  upon the Code,  applicable
Treasury Regulations thereunder, administrative rulings, and judicial authority,
all as of the date hereof.  All of the foregoing are subject to change,  and any
such change could affect the  continuing  validity of this summary.  The summary
assumes that the holders of shares of DS Bancor Common Stock hold such shares as
a capital asset. The summary does not address the tax  consequences  that may be
applicable to a particular DS Bancor  shareholder  subject to special tax rules,
such as tax-exempt organizations, dealers in securities, financial institutions,
insurance companies, non-United States persons, shareholders who acquired shares
of DS Bancor  Common  Stock  pursuant to the exercise of options or otherwise as
compensation or through a qualified  retirement  plan, and shareholders who hold
shares  of  DS  Bancor  Common  Stock  as  part  of a  "straddle,"  "hedge,"  or
"conversion  transaction."  This summary also does not address any  consequences
arising under the tax laws of any state, locality, or foreign jurisdiction.

         Consummation  of the Merger is subject to the prior  receipt by Webster
of an opinion from its counsel,  Mintz,  Levin, Cohn,  Ferris,  Glovsky & Popeo,
P.C., and by DS Bancor of an opinion from its special tax counsel, Fried, Frank,
Harris, Shriver & Jacobson (a partnership including professional  corporations),
that the Merger (either alone or in conjunction with the merger of the Surviving
Corporation  into Webster) will be treated for federal  income tax purposes as a
tax-free  reorganization  within the  meaning of  Section  368 of the Code.  The
opinions will not bind the Internal Revenue Service ("IRS") or a court and thus,
in considering whether the Merger qualifies as a tax-free  reorganization within
the  meaning  of  Section  368 of the  Code,  the IRS or a court  could  reach a
conclusion  contrary  to that  reached in the  opinions.  The Merger will not be
consummated unless the opinions of counsel are received.

         If, as concluded in the opinions of counsel,  the Merger  (either alone
or in  conjunction  with the merger of the Surviving  Corporation  into Webster)
qualifies as a tax-free  reorganization within the meaning of Section 368 of the
Code, then:

                  (1)  Except as  discussed  in (4) below  with  respect to cash
         received in lieu of a fractional  share of Webster  Common Stock,  a DS
         Bancor  shareholder will recognize no gain or loss upon the exchange of
         DS Bancor Common Stock for Webster Common Stock pursuant to the Merger.

                  (2) The tax basis of the Webster Common Stock received by a DS
         Bancor  shareholder in the Merger will be the same as the shareholder's
         tax  basis  in the DS  Bancor  Common  Stock  surrendered  in  exchange
         therefor.

                  (3) The holding period of the Webster Common Stock received by
         a DS Bancor  shareholder  in the Merger will include the holding period
         of  the  DS  Bancor  Common  Stock  surrendered  in  exchange  therefor
         (assuming the DS Bancor Common Stock was held as a capital asset).

                  (4) A DS Bancor  shareholder  who  receives  cash in lieu of a
         fractional  share of  Webster  Common  Stock  will be treated as having
         received the cash in exchange for the fractional share. Generally,  the
         shareholder  will  recognize  gain or loss (capital gain or loss if the
         shareholder  held its DS Bancor Common Stock as a capital  asset) equal
         to the  difference  between the  shareholder's  basis in the fractional
         share (determined under (2) above) and the cash received in lieu of the
         fractional share.


                                      -52-



                  (5) Neither Webster,  Merger Sub, nor DS Bancor will recognize
         any gain or loss as a result of the Merger.

         The  preceding  discussion  is  intended  only as a summary  of certain
federal  income tax  consequences  of the  Merger  and does not  purport to be a
complete  analysis or discussion of all potential tax effects relevant  thereto.
Thus, DS Bancor  shareholders  are urged to consult their own tax advisors as to
the  specific  tax  consequences  to them of the  Merger,  including  tax return
reporting  requirements,  the applicability and effect of federal,  state, local
and other applicable tax laws, and the effect of any proposed changes in the tax
laws.

ACCOUNTING TREATMENT

         The  Merger is  intended  to  qualify  as a pooling  of  interests  for
accounting  and  financial  reporting  purposes.  Under the pooling of interests
method of accounting,  the recorded  assets and liabilities of DS Bancor will be
carried forward to Webster at their recorded  amounts.  Revenues and expenses of
Webster  will include  revenues and expenses of DS Bancor for the entire  fiscal
year of  Webster in which the  Merger  occurs,  and the  reported  revenues  and
expenses of DS Bancor for prior  periods will be combined with those of Webster,
whose financial statements will then be restated.


         Webster has received  an opinion  of its independent accountants,  KPMG
Peat  Marwick  LLP,  to the effect that the Merger  will be  accounted  for as a
pooling of interests  and will  receive an update of such  opinion  prior to the
Effective  Time.  Webster's  obligation to consummate  the Merger is conditioned
upon such opinion not being withdrawn.


RESALES OF WEBSTER COMMON STOCK RECEIVED IN THE MERGER

         The shares of Webster  Common  Stock to be issued in the Merger will be
registered  under the Securities Act and will be freely  transferable  under the
Securities Act, except for shares issued to any DS Bancor shareholder who may be
deemed to be an  "affiliate"  of DS Bancor  for  purposes  of Rule 145 under the
Securities  Act.  Affiliates  may not sell their shares of Webster  Common Stock
acquired  in  connection  with  the  Merger,  except  pursuant  to an  effective
registration  statement  under the  Securities  Act  covering  such  shares,  in
compliance with Rule 145 or another  applicable  exemption from the registration
requirements of the Securities Act. This Joint Proxy  Statement/Prospectus  does
not cover any  resales of Webster  Common  Stock  received by persons who may be
deemed to be affiliates of DS Bancor. Persons who may be deemed to be affiliates
of DS  Bancor  generally  include  individuals  or  entities  who  control,  are
controlled  by or are under  common  control  with DS  Bancor,  and may  include
certain officers or directors, as well as principal shareholders of DS Bancor.

NO APPRAISAL RIGHTS

         Pursuant to Section 262(b) of the Delaware General Corporation Law, the
shareholders of a constituent corporation in a merger generally are not entitled
to  appraisal  rights if the shares of stock they own are, as of the record date
fixed to determine shareholders entitled to notice of and to vote at the meeting
to act upon the agreement providing for such merger, either listed on a national
securities  exchange or  designated as a national  market system  security on an
interdealer  quotation system by the National Association of Securities Dealers,
Inc., or held of record by more than 2,000 shareholders.

         Since DS Bancor Common Stock is traded on The Nasdaq  National  Market,
the holders of DS Bancor  Common  Stock will not be entitled to any  dissenters'
appraisal rights with respect to the Merger. The holders of Webster Common Stock
have no dissenters' appraisal rights.

INTERESTS OF CERTAIN  PERSONS IN THE MERGER - ARRANGEMENTS  WITH AND PAYMENTS TO
DS BANCOR DIRECTORS AND EXECUTIVE OFFICERS

         The Merger Agreement provides for two DS Bancor directors  (selected by
the Board of Directors of Webster) to be invited to serve as additional  members
of the Boards of Directors of Webster and Webster Bank upon  consummation of the
Merger. One director will serve until Webster's 1998 annual meeting and one will
serve  until  Webster's  1999  annual  meeting;  also,  one of the  two  will be
renominated  when his or her term  expires.  In  addition,  the  directors of DS
Bancor  serving  immediately  prior to the  Effective  Time,  including  the two
directors  who will serve on the Board of Directors of Webster,  will be invited
to serve on an advisory board to Webster Bank after the Bank Merger for a period
of 24 months,  with their  compensation  as advisory  directors to be based on a
quarterly  retainer of $4,750 and a quarterly meeting  attendance fee of $1,500.
Such  fees will not be  payable  to the DS Bancor  directors  who also  serve as
Webster directors.

         Pursuant to existing  employment and severance  agreements of DS Bancor
or Derby, as modified and limited by the Merger  Agreement,  severance  payments
will be made  upon the  consummation  of the  Merger to Harry P.  DiAdamo,  Jr.,
Alfred T. Santoro and Thomas H. Wells. These payments,  which are limited to the
maximum amount that can be paid without adverse tax  consequences  under Section
280G of the Code, will be based on three times their  respective  average annual
compensation  that was paid by Derby and  includible  in their gross  income for
federal tax purposes for the calendar years 1992 through 1996, reduced by $1.00.
Such severance  amounts will reflect the amount of taxable  compensation  income
reported by Messrs. DiAdamo, Santoro and Wells from employment by Derby in 1996,
including  taxable income  attributable to stock options  exercised during 1996.
Messrs.  DiAdamo,  Santoro and Wells have agreed to limit the maximum  amount by
which their severance  payments will be increased as a consequence of their 1996
nonqualified  stock option exercises,  and their  disqualifying  dispositions of
stock  acquired  by 1996  incentive  stock  option  exercises,  to an  amount of
additional  severance  based on the market price of DS Bancor Common Stock being
$40 per share at the times of such exercises or dispositions, as applicable.

         Based on three times their respective average annual  compensation paid
by Derby and  includible  in gross  income  for  federal  tax  purposes  for the
calendar  years 1992 through 1996, and assuming that all options held by Messrs.
DiAdamo,  Santoro and Wells are exercised, and that shares that can be purchased
upon the exercise of all incentive stock options held by them are disposed of in
disqualifying dispositions,  in each case at a time when such per share price is
$40,  the  severance  payable  to  Messrs.  DiAdamo,   Santoro  and  Wells  upon
consummation  of the Merger would be $2.7  million,  $1.7 million and  $837,000,
respectively.

         Also upon consummation of the Merger, Webster Bank has agreed to employ
Mr. Wells for a ten month period as an officer to assist in the  transition at a
salary of $10,000 per month and to retain him as a part-time  consultant for six
months thereafter at a salary of $7,500 per month.

INDEMNIFICATION

         In the Merger  Agreement,  Webster has agreed to indemnify,  defend and
hold  harmless  each person who is, has been,  or becomes prior to the Effective
Time, a director,  officer or employee of DS Bancor or Derby (collectively,  the
"Indemnitees"),  to the fullest  extent  permitted  under  applicable  law or DS
Bancor's  Amended and  Restated  Certificate  of  Incorporation  and Bylaws,  as
applicable,  with respect to any claims made  against such person  because he or
she is or was a  director,  officer  or  employee  of DS  Bancor  or Derby or in
connection with the Merger Agreement. In the Merger Agreement,  Webster has also
agreed to cover DS  Bancor's  officers  and  directors  under a  directors'  and
officers'  liability  insurance  policy for a period of at least two years after
the Effective  Time and, so long as the premium does not exceed the total amount
of $200,000, up to four years.


                                     -54-



OPTIONS

         As of the DS Bancor  Record  Date,  there were  outstanding  options to
purchase  _______ shares of DS Bancor Common Stock at an average  exercise price
of $____ per share.  These  options  are held as  follows:  ________  options by
non-employee  directors;  ________,  _______  and  ________  options  by Messrs.
DiAdamo,  Santoro  and  Wells,  respectively;  and  _________  options  by other
officers and employees.  Under the Merger Agreement,  shares of DS Bancor Common
Stock issued prior to consummation of the Merger upon the exercise of the ______
outstanding options held by directors, officers and other employees of DS Bancor
will also be converted  into Webster Common Stock at the Exchange  Ratio,  which
would involve the issuance of up to ______  additional  shares of Webster Common
Stock as part of the Merger.  Any  options  that are not  exercised  immediately
prior to the Effective Time of the Merger will be converted  automatically  into
options to purchase  Webster Common Stock,  with  adjustment in number of shares
and exercise price to reflect the Exchange  Ratio.  The duration and other terms
of these options will  otherwise be unchanged.  For purposes of the options held
by the non-employee  directors of DS Bancor,  service as an advisory director of
Webster Bank will  constitute  service  (and such  options  will  continue to be
exercisable  during  their  original  terms for up to three  months  after  such
service ends).  Options previously  granted to Messrs.  DiAdamo and Santoro will
expire upon or after  termination of  employment,  as provided in the applicable
option agreement (such agreements  generally provide for exercise during 30 days
or, in the case of options  granted  under the 1994  Stock  Option  Plan,  three
months  after  termination  of  employment,  except  in the case of  retirement,
disability  or death).  Service as an officer (but not as a  consultant)  by Mr.
Wells will constitute  continued service for purpose of exercise of his options.
Options  held by other  officers  and  employees  of DS Bancor will  continue in
effect for their  original  terms as long as they are  employees of Webster Bank
and will continue to be exercisable after termination of such employment only to
the extent provided in the applicable option agreement.

OPTION AGREEMENT

         As a condition of and inducement to Webster's  entering into the Merger
Agreement,  Webster and DS Bancor entered into the Option Agreement  immediately
after the execution of the Merger  Agreement.  Pursuant to the Option Agreement,
DS Bancor  granted  Webster  the Option,  which  entitles  Webster to  purchase,
subject to the terms thereof, up to 564,296 fully paid and nonassessable  shares
of DS Bancor Common  Stock,  or  approximately  18.6% of the shares of DS Bancor
Common Stock then  outstanding,  under the  circumstances  described below, at a
price of $36.50, subject to adjustment in certain  circumstances.  The Option is
intended  to  significantly  increase  the cost to a  potential  third  party of
acquiring DS Bancor, under specified circumstances,  compared to its cost had DS
Bancor  not  entered  into the Option  Agreement  and,  therefore,  is likely to
discourage  third parties from proposing a competing offer to acquire DS Bancor,
even if such offer  involves a higher  price per share for the DS Bancor  Common
Stock  than  the per  share  consideration  to be paid  pursuant  to the  Merger
Agreement.

         The  following  brief  summary  of  certain  provisions  of the  Option
Agreement is qualified in its entirety by reference to the Option  Agreement.  A
copy of the Option  Agreement as well as the other  documents  described in this
Joint Proxy  Statement/Prospectus  will be provided  without charge upon oral or
written  request to Lee A. Gagnon,  Executive Vice  President,  Chief  Operating
Officer  and  Secretary  of  Webster  Financial   Corporation,   Webster  Plaza,
Waterbury, Connecticut 06702, telephone (203) 578-2217.

         Subject to  applicable  law and  regulatory  restrictions,  Webster may
exercise  the  Option,  in whole  or in  part,  following  the  occurrence  of a
"Purchase  Event" (as defined  below),  provided  that the Option shall not have
first  terminated  upon the  occurrence of an "Exercise  Termination  Event" (as
defined below). "Purchase Event" means, in substance, either (i) the acquisition
by any third party of beneficial  ownership of 25% or more of the outstanding DS
Bancor  Common  Stock or (ii) the entry by DS Bancor  into a letter of intent or
definitive agreement to engage in an Acquisition  Transaction (as defined below)
with any third party, or the recommendation by the Board of


                                      -55-


Directors of DS Bancor that its  shareholders  approve or accept any Acquisition
Transaction with any third party.

         For purposes of the Option Agreement,  "Acquisition  Transaction" means
(x) a merger, consolidation or other business combination,  involving DS Bancor,
(y) a purchase,  lease or other  acquisition of all or substantially  all of the
assets of DS Bancor, or (z) a purchase or other acquisition (including by way of
merger,  consolidation,  share exchange or otherwise) of beneficial ownership of
25% or more of the voting power of DS Bancor as to a Purchase  Event  (described
above) or 15% as to a Preliminary Purchase Event (defined below).

         The Option Agreement  defines an "Exercise  Termination  Event" to mean
the earliest to occur of the following:  (i) the time  immediately  prior to the
Effective  Time of the Merger;  (ii) 12 months after the first  occurrence  of a
Purchase Event;  (iii) 18 months after the  termination of the Merger  Agreement
following  the  occurrence  of a  Preliminary  Purchase  Event;  (iv)  upon  the
termination of the Merger Agreement, prior to the occurrence of a Purchase Event
or  Preliminary  Purchase  Event,  (A) by DS Bancor,  if the Base Period Trading
Price of Webster  Common Stock is less than $28.00 unless  Webster takes certain
specified action; (B) by both parties,  if the Merger Agreement is terminated by
mutual consent;  (C) by either Webster or DS Bancor, if the Merger Agreement has
been  terminated as a result of regulatory  denial or requested  withdrawal of a
regulatory  application,  if the Merger has not occurred by June 30, 1997, or if
the Merger  Agreement is terminated  because the approval of the shareholders of
Webster  or DS  Bancor  is not  obtained;  or (D) by DS  Bancor,  if the  Merger
Agreement is terminated as a result of a material breach of any  representation,
warranty,  covenant  or other  agreement  by  Webster;  (v) 135 days  after  the
termination of the Merger Agreement,  if the DS Bancor  shareholders have failed
to approve the Merger  Agreement and no Purchase Event or  Preliminary  Purchase
Event has occurred  prior to the DS Bancor  Meeting;  (vi) nine months after the
termination of the Merger  Agreement by Webster as a result of a material breach
or breaches of any representation,  warranty,  covenant or other agreement by DS
Bancor, if such breach or breaches were not willful or intentional by DS Bancor;
or (vii) 24 months after the termination of the Merger  Agreement by Webster (A)
as a result of a willful  or  intentional  material  breach or  breaches  of any
representation, warranty, covenant or agreement by DS Bancor; or (B) as a result
of a  failure  of DS  Bancor  or its  Board of  Directors  to hold the DS Bancor
Meeting on a timely basis,  to recommend to DS Bancor's  shareholders  that they
approve the Merger Agreement (with a fiduciary duty exception), or to oppose any
third party takeover  proposal (with a fiduciary duty exception),  or based on a
violation  by DS  Bancor  of the  covenant  on third  party  takeover  proposals
(without regard to the fiduciary duty exception).

         "Preliminary  Purchase  Event",  as defined  in the  Option  Agreement,
includes  (i) the  entry by DS Bancor  into a letter  of  intent  or  definitive
agreement to engage in an Acquisition  Transaction  with any third party, or the
recommendation  by the Board of  Directors  of DS Bancor  that its  shareholders
approve or accept any  Acquisition  Transaction  with any third  party;  (ii) an
acquisition  by any third party of  beneficial  ownership  of 15% or more of the
outstanding DS Bancor Common Stock; (iii) the making of a bona fide proposal for
an  Acquisition  Transaction  by any  third  party  to DS  Bancor,  or a  public
announcement or written  communication that is publicly disclosed to DS Bancor's
shareholders as to a third party engaging in an Acquisition Transaction;  (iv) a
willful  or  intentional  material  breach by DS  Bancor of any  representation,
warranty,  covenant or agreement  that would  entitle  Webster to terminate  the
Merger  Agreement;  (v) a failure by DS  Bancor's  shareholders  to approve  the
Merger Agreement,  a withdrawal or modification in any manner adverse to Webster
by DS Bancor's  Board of  Directors  of its  approval  recommendation  as to the
Merger Agreement,  or a failure by DS Bancor or its Board of Directors to oppose
any third  party  takeover  proposal;  or (vi) a filing by any third party of an
application or notice with any regulatory authority for approval to engage in an
Acquisition Transaction.

         The Option may not be assigned by Webster to any other  person  without
the express  written  consent of DS Bancor,  except that  Webster may assign its
rights under the Option Agreement to a wholly-owned subsidiary or may assign its
rights in whole or in part after the occurrence of a Preliminary Purchase Event.
DS Bancor also has agreed to prepare and file a registration

                                      -56-



statement  if the Option is  exercised  with  respect to the shares to be issued
upon exercise of the Option under applicable  federal and state securities laws.
Upon the occurrence of a Purchase Event prior to an Exercise  Termination Event,
at the request of Webster, DS Bancor will be obligated to repurchase the Option,
and any shares of DS Bancor Common Stock theretofore  purchased  pursuant to the
Option, at prices determined as set forth in the Option Agreement, except to the
extent prohibited by applicable law,  regulation or administrative  policy or to
the extent that the  repurchase  would cause  Derby's  capital to fall below the
minimum  level  required by the FDIC for Derby to be deemed a  "well-capitalized
institution"  or if such  repurchase  would preclude an Acquisition  Transaction
from being accounted for as a pooling of interests.


         In the event that prior to an  Exercise  Termination  Event,  DS Bancor
enters into a letter of intent or  definitive  agreement (i) to  consolidate  or
merge with any third  party,  and DS Bancor is not the  continuing  or surviving
corporation in such  consolidation or merger;  (ii) to permit any third party to
merge into DS Bancor and DS Bancor is the  continuing or surviving  corporation,
but, in connection with such merger,  the then  outstanding  shares of DS Bancor
Common Stock shall be changed into or exchanged for stock or other securities of
any third party or cash or any other property or the then outstanding  shares of
DS Bancor  Common  Stock will after such merger  represent  less than 50% of the
outstanding shares and share equivalents of the merged company; or (iii) to sell
or otherwise transfer all or substantially all of its assets to any third party,
then, and in each such case, the agreement  governing such transaction must make
proper  provision  so that  the  Option  shall,  upon the  consummation  of such
transaction,  be converted  into, or exchanged  for, an option (the  "Substitute
Option"), at the election of Webster, of either (x) the acquiring corporation or
(y) any person that controls the acquiring  corporation.  The Substitute  Option
will be exercisable  for shares of the issuer's  common stock in such number and
at such  exercise  price  as is set  forth  in the  Option  Agreement  and  will
otherwise  have the same terms as the  Option,  except that the number of shares
subject  to  the  Substitute  Option  may  not  exceed  19.9%  of  the  issuer's
outstanding shares of common stock.

                         AMENDMENT TO WEBSTER'S RESTATED
                          CERTIFICATE OF INCORPORATION

         The Webster  Board of Directors  unanimously  approved the amendment to
Webster's Restated Certificate of Incorporation to increase Webster's authorized
capital stock by increasing  the number of authorized  shares of Webster  Common
Stock from  14,000,000 to  30,000,000,  and  determined  that such  amendment is
advisable and in the best interests of Webster and its shareholders. The Webster
Board therefore unanimously  recommends that the holders of Webster Common Stock
vote  to  approve  the   amendment  to   Webster's   Restated   Certificate   of
Incorporation.

         Webster's Restated Certificate of Incorporation currently provides that
the total number of shares of all classes of capital  stock that Webster has the
authority to issue is  17,000,000,  consisting of  14,000,000  shares of Webster
Common Stock and 3,000,000  shares of serial preferred stock, par value $.01 per
share. The proposed amendment to Webster's Restated Certificate of Incorporation
is to increase  the number of  authorized  shares of Webster  Common  Stock from
14,000,000 to  30,000,000,  resulting in an increase in the  authorized  capital
stock that Webster has the  authority to issue from  17,000,000  to  33,000,000.
Such  increase  will be  effected by  amending  the first  sentence of the first
paragraph of Article 4 of Webster's  Restated  Certificate of  Incorporation  to
read as follows:

                  "The  total  number of shares of all  classes  of the  capital
                  stock  which  the   Corporation  has  authority  to  issue  is
                  thirty-three  million  (33,000,000),  of which thirty  million
                  (30,000,000)  shall be common stock, par value $.01 per share,
                  amounting in the aggregate to three hundred  thousand  dollars
                  ($300,000),  and  three  million  (3,000,000)  shall be serial
                  preferred  stock,  par value $.01 per share,  amounting in the
                  aggregate to thirty thousand dollars ($30,000)."

         Of the 14,000,000  presently authorized shares of Webster Common Stock,
___________  shares were issued and  outstanding on the Webster Record Date, and
________,  _________,  and  ________  shares,  respectively,  were  reserved for
issuance with respect to Webster stock options, the warrant issued by Webster to
Fleet  Financial  Group,  Inc. for 300,000  shares of Webster  Common Stock (the
"Webster  Warrant")  and  Webster's  Series B Stock (which is  convertible  into
Webster  Common  Stock).  Of the 1,200,000  presently  authorized  shares of the
Series B Stock,  ________  shares  were  issued and  outstanding  on the Webster
Record Date.  No shares of Webster's  Series A  Cumulative  Perpetual  Preferred
Stock,  par value $.01 per share  ("Series  A Stock") or Series C  Participating
Preferred  Stock,  par value $.01 per share  ("Series  C Stock")  are issued and
outstanding. Accordingly, on the Webster Record Date, _____ shares of authorized
but not  outstanding  and  unreserved  shares of Webster  Common Stock  remained
available for future issuance (before giving effect to the  approximately  __*__
shares to be issued in the  Merger  based on  recent  market  trading  prices of
Webster  Common  Stock,  and  ___*___ if all  existing  options of DS Bancor are
exercised prior to the Merger) and _________ and _________ shares, respectively,
of Webster's  Series B Stock and Series C Stock,  remained  available for future
issuance.  No shares of  Webster's  Series A Stock remain  available  for future
issuance.  For a description of Webster's  capital stock,  see  "DESCRIPTION  OF
WEBSTER CAPITAL STOCK AND COMPARISON OF SHAREHOLDER RIGHTS."

         If the Merger  Agreement  and the Merger  provided  for therein and the
amendment to Webster's  Restated  Certificate of Incorporation are approved,  at
the Effective  Time,  ___*___  shares of Webster  Common Stock will be issued in
connection  with the  Merger  based on a __*__  Exchange  Ratio ( ___*___ if all
existing  options of DS Bancor are  exercised  prior to the Merger).  Therefore,
giving effect to the Merger, of the then __________ shares of authorized Webster
Common Stock,

     effectiveness of Registration Statement.

                                      -58-




________ will be issued and  outstanding  (including all existing  options of DS
Bancor) and ________, _______, and ________,  respectively, will be reserved for
issuance  with respect to Webster  stock  options,  the Webster  Warrant and the
potential conversion of the issued and outstanding shares of the Series B Stock.
Accordingly,  after the  Merger  (based on a __*__  Exchange  Ratio),  ____*____
shares of authorized but not outstanding and unreserved shares of Webster Common
Stock (____*____ if all existing options of DS Bancor are exercised prior to the
Merger) and  ________  and  ____________  shares  of Series B Stock and Series C
Stock, respectively, will be available for future issuance.

         Approval of the proposed amendment to Webster's Restated Certificate of
Incorporation is not a condition to the Merger Agreement.

         Although  Webster has no present  intention of issuing  authorized  but
unissued and unreserved shares of Webster capital stock other than in connection
with the Merger,  Webster stock options,  the Webster  Warrant and the potential
conversion of Series B Stock,  the Webster Board of Directors  believes that the
increased  number of shares of  Webster  Common  Stock will  benefit  Webster by
making  a  sufficient  number  of  shares  available  in the  future  for use in
connection  with  possible  stock  dividends  or stock  splits,  the  raising of
additional  capital through a potential  public  offering or private  placement,
possible future mergers or acquisitions,  under a cash dividend  reinvestment or
stock purchase plan or under an employee stock  ownership plan. The unissued and
unreserved  shares of Webster Common Stock and Webster  preferred  stock will be
available for any proper corporate  purpose,  as authorized from time to time by
the Board of Directors, without further approval by the shareholders of Webster,
except as otherwise required by law.

         Webster  shareholders  do not have  any  preemptive  or stock  purchase
rights to purchase  additional  shares of Webster  Common Stock,  whether now or
hereafter  authorized.  Further issuances of additional shares of Webster Common
Stock or securities convertible into Webster Common Stock, therefore, may have a
dilutive effect on existing shareholders.

         As a Delaware  corporation,  Webster is taxed on its authorized capital
stock.  In general,  the annual  franchise tax is $90 on the first 10,000 shares
and the further sum of $50 on each  additional  10,000  shares or part  thereof.
Currently,  Webster's annual franchise tax is $85,000.  Increasing the number of
authorized shares of Webster Common Stock to 30,000,000 will result in an annual
franchise tax of $150,000.

         In the event of a proposed  merger,  tender  offer or other  attempt to
gain  control of  Webster  of which  management  does not  approve,  it might be
possible for the Board of Directors to approve the issuance of shares of Webster
Common Stock or Webster  preferred  stock in a  transaction  that could have the
effect of frustrating or impeding such takeover attempt.  The Board of Directors
has no  current  intention  to issue  authorized  but  unissued  shares for such
purpose.  The  Board  of  Directors  is not  aware  of any  specific  effort  to
accumulate  Webster's  capital  stock in order to obtain  control  by means of a
merger, tender offer or otherwise.

         Shareholders  are  advised  to obtain  current  market  quotations  for
Webster  Common Stock.  It is expected  that the market price of Webster  Common
Stock will fluctuate  between the date of this Joint Proxy  Statement/Prospectus
and the date on which the Merger is consummated. Because the number of shares of
Webster Common Stock to be received by DS Bancor  shareholders  in the Merger is
not fixed,  the Exchange  Ratio for the number of shares of Webster Common Stock
that the  holders  of DS Bancor  Common  Stock  would  receive in the Merger may
increase or decrease prior to the Merger.

                    DESCRIPTION OF WEBSTER CAPITAL STOCK AND
                        COMPARISON OF SHAREHOLDER RIGHTS

         Set forth below is a description of Webster's capital stock, as well as
a summary of the material differences between the rights of holders of DS Bancor
Common Stock and their prospective rights as holders of Webster Common Stock. If
the Merger  Agreement  is approved and adopted and the Merger  consummated,  the
holders of DS Bancor Common Stock will become  holders of Webster  Common Stock.
As a result, Webster's Restated Certificate of Incorporation and Bylaws, and the
applicable  provisions  of  Delaware  law,  will  govern  the  rights of current
shareholders  of DS Bancor Common Stock.  The rights of those  shareholders  are
currently governed by the Amended and Restated  Certificate of Incorporation and
Bylaws of DS Bancor, and the applicable provisions of Delaware law.

         The following comparison is based on the current terms of the governing
documents of Webster and DS Bancor and on the  provisions of Delaware law, which
is  applicable  to both  Webster and DS Bancor.  The  discussion  is intended to
highlight  important  similarities and differences between the rights of holders
of Webster Common Stock and DS Bancor Common Stock.

WEBSTER COMMON STOCK

         Webster is  authorized  to issue  14,000,000  shares of Webster  Common
Stock and, if the amendment to approve the increase in the authorized  number of
shares of Webster  Common  Stock is  approved  by  shareholders  at the  Webster
Meeting,  Webster will be authorized  to issue a total of  30,000,000  shares of
Webster  Common Stock.  As of the Webster  Record Date,  _____ shares of Webster
Common  Stock  were  issued  and  outstanding  and  after  giving  effect to the
conversion of the outstanding  Series B Stock of Webster described below,  there
would be ______________ additional shares of Webster Common Stock, or a total of
______________  shares of Webster  Common  Stock then  outstanding.  Webster has
outstanding stock options granted to directors, officers and other employees for
______________  shares of Webster Common Stock.  Webster has issued a warrant to
Fleet  Financial  Group,  Inc. for 300,000 shares of Webster Common Stock.  Each
share of Webster  Common Stock has the same relative  rights and is identical in
all respects to each other share of Webster  Common  Stock.  The Webster  Common
Stock  is  non-withdrawable  capital,  is not of an  insurable  type  and is not
insured by the FDIC or any other governmental entity.

         Holders of Webster  Common  Stock are entitled to one vote per share on
each matter  properly  submitted to shareholders  for their vote,  including the
election of directors.  Holders of Webster Common Stock do not have the right to
cumulate their votes for the election of directors, and they have no pre-emptive
or  conversion  rights with  respect to any shares  that may be issued.  Webster
Common Stock is not subject to additional  calls or assessments by Webster,  and
all shares of Webster  Common  Stock  currently  outstanding  are fully paid and
nonassessable.

         Holders of Webster Common Stock are entitled to receive  dividends when
and as  declared  by the Board of  Directors  of Webster  out of assets  legally
available for distribution.  No dividends or other distributions may be declared
or paid on Webster Common Stock, however,  unless all accumulated dividends have
been paid  concurrently on the Series B Stock or any other class of stock having
preference over the Webster Common Stock. In addition,  as described  below, the
Indenture (as defined below) for the Senior Notes places certain restrictions on
Webster's  ability to pay  dividends  on Webster  Common  Stock.  See "-- Senior
Notes."

         In the unlikely event of any liquidation or dissolution of Webster, the
holders of Webster  Common Stock would be entitled to receive,  after payment or
provision for payment of all debts and  liabilities of Webster and after payment
of the liquidation preferences of all outstanding shares of preferred stock, all
remaining assets of Webster available for distribution, in cash or in kind.


                                      -70-




SERIES B STOCK

         Webster's Restated Certificate of Incorporation authorizes its Board of
Directors, without further shareholder approval, to issue up to 3,000,000 shares
of serial  preferred stock for any proper  corporate  purpose.  In approving any
issuance of serial  preferred  stock, the Board of Directors has broad authority
to determine the rights and preferences of the serial preferred stock, which may
be issued in one or more  series.  These  rights  and  preferences  may  include
voting,  dividend,  conversion and liquidation  rights that may be senior to the
Webster Common Stock.

         Of  the  3,000,000   authorized   shares  of  serial  preferred  stock,
__________ shares of Series B Stock were outstanding on the Webster Record Date.
The Series B Stock  ranks  prior to the  Webster  Common  Stock with  respect to
dividends  and amounts  distributable  upon  liquidation.  The Series B Stock is
entitled to receive,  when  declared by the Board of  Directors  out of funds of
Webster legally available  therefor,  cumulative  quarterly cash dividends at an
annual rate of 7 1/2%.  Unless full  cumulative  dividends on the Series B Stock
have been paid,  dividends  (other than in Webster Common Stock) may not be paid
or declared upon the Webster Common Stock. Upon any liquidation of Webster,  the
holders of the Series B Stock will be  entitled  to receive out of the assets of
Webster  available for distribution to its shareholders  before any distribution
is made to  holders  of the  Webster  Common  Stock an amount  equal to $100 per
share,  plus an amount  equal to all  dividends  accumulated  and  unpaid on the
Series B Stock to the date of final distribution.

         Except as indicated below or as required by law,  holders of the Series
B Stock have no voting rights. If at any time six quarterly dividends payable on
the Series B Stock are accrued and unpaid, the number of directors of Webster is
required  to be  increased  by two and the  holders  of all the  Series B Stock,
voting as a single  class,  will be entitled to elect two  additional  directors
until all dividends accumulated on the Series B Stock have been paid in full. In
addition,  without the vote or consent of the holders of at least  two-thirds of
the Series B Stock then outstanding,  Webster may not (i) amend, alter or repeal
any of the  provisions of its  certificate  of  incorporation  or certificate of
designation  so as to affect  adversely the  preference or power of the Series B
Stock; (ii) authorize any reclassification of the Series B Stock; or (iii) issue
any  shares  of any class or series  of stock of  Webster  ranking  prior to the
shares of the Series B Stock as to dividends or upon liquidation,  or reclassify
any  authorized  stock of  Webster  into  any such  prior  shares  or issue  any
obligation or security  convertible into or evidencing the right to purchase any
such prior  shares.  Accordingly,  the voting  rights of the holders of Series B
Stock could under  certain  circumstances  operate to restrict  the  flexibility
which Webster would  otherwise have in connection  with any future  issuances of
equity securities or changes to its capital structure.

         The Series B Stock is not subject to any  mandatory  redemption  at the
election  of the holder or  sinking  fund  provision.  The Series B Stock may be
redeemed for cash at the option of Webster,  in whole or in part, at any time on
or  after  January  15,  1997,  on at least 15 days  notice,  at the  applicable
redemption price,  plus accumulated and unpaid  dividends.  The redemption price
initially  will be $104.50 per share  effective  as of January 15, 1997 and will
decline to $100.00  after  January 15, 2003.  Holders of Series B Stock have the
right, at their option,  at any time to convert the Series B Stock into a number
of fully paid and nonassessable  shares of Webster Common Stock equal to $100.00
for each share  surrendered  for  conversion  divided by the  conversion  price,
subject to certain exceptions following a notice of redemption by Webster.

SERIES A STOCK

         Webster's  Series A Stock  was  issued  in  connection  with the  First
Constitution acquisition. See "RISK FACTORS -- Growth through Acquisitions." All
of the  shares  of Series A Stock  that were  authorized  and  issued  have been
redeemed.


                                      -71-



SERIES C STOCK

         Webster's   Series  C  Stock  was  authorized  in  connection   with  a
Stockholders'  Rights Plan,  which was adopted in January 1996.  Webster adopted
the  Stockholders'  Rights  Plan to  protect  shareholders  in the  event  of an
inadequate takeover offer or to deter coercive or unfair takeover tactics.  Each
right entities a holder to purchase  1/1,000th of a share of Series C Stock upon
the occurrence of certain  specified  events. As of the date of this Joint Proxy
Statement/Prospectus, no shares of Series C Stock have been issued.

SENIOR NOTES

         The 8 3/4% Senior Notes due 2000 were issued by Webster in an aggregate
principal  amount of  $40,000,000  pursuant to an Indenture  (the  "Indenture"),
dated as of June 15, 1993,  between  Webster and Chemical  Bank, as trustee (the
"Trustee").  Certain provisions of the Indenture are summarized below because of
their impact on the Webster  Common  Stock.  The Senior Notes bear interest at 8
3/4% payable  semi-annually  on each June 30 and  December 30 until  maturity on
June 30,  2000.  The Senior  Notes are  unsecured  general  obligations  only of
Webster  and not of its  subsidiaries.  The Senior  Notes may not be redeemed by
Webster  prior  to  maturity.   This  provision  is  not  expected  to  have  an
anti-takeover  effect,  since the Notes  would be  assumed  by any  acquirer  of
Webster.  The Indenture  contains  covenants that limit Webster's ability at the
holding company level to incur additional Funded  Indebtedness  (defined below),
to  make  Restricted   Distributions  (defined  below),  to  engage  in  certain
dispositions affecting Webster Bank or its voting stock, to create certain liens
upon Webster's  assets at the holding company level (including a negative pledge
clause),  and to engage in mergers,  consolidations,  or a sale of substantially
all of Webster's assets unless certain  conditions are satisfied.  The Indenture
also  requires that Webster  maintain a specified  level of liquid assets at the
holding company level.

         Restrictions  on  Additional  Indebtedness.  The  Indenture  limits the
amount of Funded  Indebtedness  which  Webster  may  incur or  guarantee  at the
holding company level.  Funded  Indebtedness  includes any obligation of Webster
with a  maturity  in excess of one year for  borrowed  money,  for the  deferred
purchase price of property or services,  for capital lease payments,  or related
to the  guarantee of such  obligations.  Webster may not incur or guarantee  any
Funded  Indebtedness if, immediately after giving effect thereto,  the amount of
Funded  Indebtedness  of Webster at the holding  company  level,  including  the
Senior Notes, would be greater than 90% of Webster's  consolidated net worth. As
of September 30, 1996,  Webster's  consolidated net worth was $216.7 million and
it had $42.5 million of Funded Indebtedness.

         Restricted  Distributions.   Under  the  Indenture,  Webster  may  not,
directly or  indirectly,  make any  Restricted  Distribution,  except in capital
stock of Webster,  if, at the time or after giving effect thereto:  (a) an event
of default  shall have  occurred  and be  continuing  under the  Indenture;  (b)
Webster  Bank  would  fail  to  meet  any  of  the  applicable  minimum  capital
requirements  under  OTS  regulations;   (c)  Webster  would  fail  to  maintain
sufficient  liquid  assets to comply  with the terms of the  covenant  described
under  "Liquidity  Maintenance"  below;  or  (d)  the  aggregate  amount  of all
Restricted  Distributions  subsequent  to March 31, 1993 would exceed the sum of
(i) $5 million, plus (ii) 75% of Webster's aggregate consolidated net income (or
if such aggregate consolidated net income shall be a deficit, minus 100% of such
deficit) accrued on a cumulative basis in the period commencing on June 30, 1993
and ending on the last day of the fiscal quarter immediately  preceding the date
of the Restricted Distribution, and plus (iii) 100% of the net proceeds received
by Webster from any capital stock issued by Webster (other than to a subsidiary)
subsequent to March 31, 1993. As of September 30, 1996,  Webster had the ability
to pay $107.3 million in Restricted Distributions.

         Restricted Distribution means: (a) any dividend,  distribution or other
payment  (except for  dividends,  distributions  or payments  payable in capital
stock or dividends on the Series B Stock) on the capital stock of Webster or any
subsidiary (other than a wholly owned subsidiary);  (b) any payment to purchase,
redeem, acquire or retire any capital stock of Webster (other than the Series

                                      -72-


A Stock,  which was  previously  redeemed),  the capital stock of any subsidiary
(other  than a  wholly-owned  subsidiary);  and (c) any  payment  by  Webster of
principal  (whether a prepayment,  redemption or at maturity) of, or to acquire,
any  indebtedness for borrowed money issued or guaranteed by Webster (other than
the Senior Notes or pursuant to a guarantee  by Webster of any  borrowing by any
employee  stock  ownership  plan  established  by  Webster  or  a  wholly  owned
subsidiary),  except  that  any  such  payment  of,  or  to  acquire,  any  such
indebtedness  for borrowed  money that is not  subordinated  to the Senior Notes
will not constitute a Restricted  Distribution,  if such indebtedness was issued
or  guaranteed by Webster at a time when the Senior Notes were rated in the same
or higher rating category as the rating assigned to the Senior Notes by Standard
& Poor's ("S&P") at the time the Senior Notes were issued.

         Liquidity Maintenance.  The Indenture requires that Webster maintain at
all times, on an  unconsolidated  basis,  liquid assets in an amount equal to or
greater than 150% of the aggregate  interest expense on the Senior Notes and all
other  indebtedness  for borrowed  money of Webster for 12 full calendar  months
immediately following each determination date under the Indenture, provided that
Webster  will not be  required to  maintain  such liquid  assets once the Senior
Notes have been rated "BBB-" or higher by S&P for six calendar months and remain
rated in such category.

CERTIFICATE OF INCORPORATION AND BYLAW PROVISIONS

         General.  Certain provisions included in Webster's Restated Certificate
of  Incorporation  and Bylaws may serve to entrench  current  management  and to
prevent  a change in  control  of  Webster  even if  desired  by a  majority  of
shareholders.  These provisions are designed to encourage potential acquirers to
negotiate  directly  with the Board of  Directors  of Webster and to  discourage
other  takeover  attempts.  The  following  discussion  is a general  summary of
certain  provisions  of Webster's  Restated  Certificate  of  Incorporation  and
Bylaws,  and a comparison of those  provisions to similar types of provisions in
DS Bancor's Amended and Restated  Certificate of Incorporation  and Bylaws.  The
discussion is necessarily  general and, with respect to provisions  contained in
Webster's  Certificate of Incorporation and Bylaws,  reference should be made to
the document in question,  each of which is an exhibit to Webster's registration
statement.

         Directors.  Certain  provisions of Webster's  Restated  Certificate  of
Incorporation  and Bylaws will impede  changes in majority  control of Webster's
Board of Directors.  The Restated Certificate of Incorporation provides that the
Board of Directors  will be divided into three  classes,  with directors in each
class elected for three-year  staggered  terms. The Bylaws provide that the size
of the  Board of  Directors,  within  the  seven to 15  range  specified  in the
Restated  Certificate of Incorporation,  may be increased or decreased only by a
two-thirds  vote of the Board of Directors  and by a vote of  two-thirds  of the
shares eligible to be voted at a duly constituted meeting of shareholders called
for such purpose.  The Restated  Certificate  of  Incorporation  provides that a
vacancy occurring in the Board of Directors,  including a vacancy created by any
increase  in the number of  directors,  may be filled for the  remainder  of the
unexpired  term by a majority vote of the directors  then in office.  The Bylaws
also impose certain restrictions on the nomination by shareholders of candidates
for  election  to the Board of  Directors  or the  proposal by  shareholders  of
business to be acted upon at an annual meeting of shareholders.

         Webster's  Restated  Certificate  of  Incorporation   provides  that  a
director may be removed only for cause and then only by the affirmative  vote of
two-thirds of the total shares eligible to vote at a duly constituted meeting of
the shareholders called expressly for that purpose.  The Restated Certificate of
Incorporation also provides that 30 days' written notice must be provided to any
director or  directors  whose  removal is to be  considered  at a  shareholders'
meeting called for such purpose.

         The  provisions  of DS Bancor's  Amended and  Restated  Certificate  of
Incorporation and Bylaws with regard to directors are substantially identical as
those of Webster's, except that the

                                      -73-



range as to the number of  directors  is nine to 16 in DS  Bancor's  Amended and
Restated Certificate of Incorporation.

         Call  of  Special   Meetings.   Webster's   Restated   Certificate   of
Incorporation  contains a provision  which  provides  that a special  meeting of
shareholders  may be called at any time but only by the chairman of the board or
the  president  of Webster or by its Board of  Directors.  Shareholders  are not
authorized  to  call  a  special  meeting.  DS  Bancor's  Amended  and  Restated
Certificate of Incorporation is the same as to special meetings.

         Cumulative Voting.  The  certificates  of incorporation of both Webster
and DS Bancor deny cumulative voting rights in the election of directors.

         Authorized and Outstanding  Common Stock. See "-- Webster Common Stock"
as to authorized and currently  outstanding  shares of Webster Common Stock.  DS
Bancor has  6,000,000  authorized  shares of common  stock,  par value $1.00 per
share, of which  __________  shares were  outstanding as of the DS Bancor Record
Date. In addition,  as of the DS Bancor  Record Date, DS Bancor had  outstanding
stock  options  granted to  directors,  officers and other  employees for ______
shares of DS Bancor  Common  Stock,  plus the  Option for  564,296  shares of DS
Bancor Common Stock granted to Webster in connection with the Merger.

         Authorized and Outstanding  Serial  Preferred  Stock.  See "-- Series B
Stock,"  "-- Series A Stock" and "--  Series C Stock" as to the  authorized  and
currently  outstanding shares of serial preferred stock of Webster.  DS Bancor's
Amended and Restated Certificate of Incorporation authorizes 2,000,000 shares of
serial  preferred  stock,  no par value, of which no shares have been issued and
are outstanding.

         Approvals for Acquisitions of Control.  Webster's Restated  Certificate
of Incorporation  prohibits any person (whether an individual,  company or group
acting  in  concert)  from  acquiring  beneficial  ownership  of 10% or  more of
Webster's voting stock,  unless the acquisition has received the prior approvals
of two-thirds of Webster's outstanding voting shares and of all required federal
regulatory authorities.  Furthermore, no person may make an offer to acquire 10%
or more of Webster's voting stock without  obtaining prior approval of the offer
by a two-thirds vote of Webster's Board of Directors or,  alternatively,  before
the offer is made,  obtaining  approval of the  acquisition  from the OTS. These
provisions do not apply to the purchase of shares by  underwriters in connection
with a public offering,  and the provisions  remain effective only so long as an
insured institution is a majority-owned  subsidiary of Webster.  Shares acquired
in  excess  of  these  limitations  are not  entitled  to  vote  or  take  other
shareholder  action or be counted in determining the total number of outstanding
shares of voting  stock in  connection  with any  matter  involving  shareholder
action. These excess shares are also subject to transfer to a trustee,  selected
by Webster,  for the sale on the open market or otherwise,  with the expenses of
the trustee to be paid out of the proceeds of such sale.  These  limitations  on
offers and purchases do not apply to the employee stock  ownership plan or other
employee benefits plans of Webster.

         DS Bancor's Amended and Restated Certificate of Incorporation  contains
substantially identical provisions as to approvals for acquisition of control of
DS Bancor,  except that  specified  state and federal  regulatory  approvals are
required.

         Procedures  for  Certain  Business  Combinations.   Webster's  Restated
Certificate of Incorporation requires that certain business combinations between
Webster (or any majority-owned subsidiary thereof) and a 10% or more shareholder
or its affiliates  (collectively,  the "Interested  Shareholder")  either (i) be
approved by at least 80% of the total  number of  outstanding  voting  shares of
Webster,  or (ii) be approved by  two-thirds  of Webster's  continuing  Board of
Directors (persons serving prior to the Interested Shareholder becoming such) or
involve  consideration  per share generally equal to that paid by the Interested
Shareholder  when it  acquired  its  block  of  stock.  The  types  of  business
combinations with an Interested  Shareholder  covered by this provision include:
mergers,  consolidations and stock exchanges; a sale, lease, exchange, mortgage,
pledge or

                                      -74-


other transfer of assets other than in the usual and regular course of business;
an issuance by Webster of its equity  securities having a market value in excess
of 5% of aggregate market value of its outstanding  shares;  the adoption of any
plan of  liquidation  of Webster or any  subsidiary  proposed  by an  Interested
Shareholder;  and any  reclassification  of  securities or  recapitalization  of
Webster which has the effect of increasing the  proportionate  equity  ownership
interest  of the  Interested  Shareholder.  DS  Bancor's  Amended  and  Restated
Certificate of Incorporation contains a substantially  identical provision as to
business combinations.

         Anti-Greenmail.   Webster's   Restated   Certificate  of  Incorporation
requires  approval by a majority of the outstanding  voting stock before Webster
may  directly or  indirectly  purchase  or  otherwise  acquire any voting  stock
beneficially  owned by a holder of 5% percent or more of Webster's voting stock,
if such  holder  has  owned  the  shares  for less than two  years.  Any  shares
beneficially  held by such  person  would be excluded  in  calculating  majority
shareholder approval. This provision would not apply to a pro rata offer made by
Webster to all of its  shareholders  in compliance with the Exchange Act and the
rules and regulations thereunder or a purchase of voting stock by Webster if the
Board of Directors  has  determined  that the purchase  price per share does not
exceed the fair market  value of such  voting  stock.  DS  Bancor's  Amended and
Restated Certificate of Incorporation contains a similar provision.

         Criteria for  Evaluating  Offers.  Webster's  Restated  Certificate  of
Incorporation  provides  that  the  Board  of  Directors,  when  evaluating  any
acquisition  offers,  shall  give due  consideration  to all  relevant  factors,
including,  without limitation,  the economic effects of acceptance of the offer
on depositors,  borrowers and employees of its insured institution  subsidiaries
and on the  communities in which such  subsidiaries  operate or are located,  as
well as on the ability of such subsidiaries to fulfill the objectives of insured
institutions  under applicable  federal  statutes and  regulations.  DS Bancor's
Amended and  Restated  Certificate  of  Incorporation  contains a  substantially
identical provision as to Derby.

         Amendment to Certificate  of  Incorporation  and Bylaws.  Amendments to
Webster's Restated Certificate of Incorporation must be approved by a two-thirds
vote of Webster's  Board of Directors and also by a majority of the  outstanding
shares of Webster's voting stock; provided, however, that approval by two-thirds
of the outstanding voting stock is generally required for certain provisions. In
addition,  the provisions regarding certain business combinations may be amended
only by the same "80 percent"  shareholder  vote  required to approve a business
combination  with  a 10%  shareholder.  Webster's  Bylaws  may be  amended  by a
two-thirds  vote of the Board of  Directors  or a  two-thirds  vote of the total
shares  eligible  to be voted at a duly  constituted  meeting  of  shareholders.
Amendments to DS Bancor's Amended and Restated  Certificate of Incorporation and
Bylaws are subject to substantially identical provisions as those of Webster's.

Applicable Law

         The following  discussion is a general summary of certain provisions of
Delaware,  Connecticut and federal statutory and regulatory  provisions that may
be deemed to have an "anti-takeover" effect.

         Delaware  Takeover  Statute.   Section  203  of  the  Delaware  General
Corporation  Law  (the  "Delaware   Takeover   Statute")   applies  to  Delaware
corporations  with a class of  voting  stock  listed  on a  national  securities
exchange,  authorized for quotation on an inter-dealer quotation system, or held
of record by 2,000 or more  persons,  and  restricts  transactions  which may be
entered into by such a corporation and certain of its shareholders. The Delaware
Takeover Statute provides,  in essence,  that a shareholder  acquiring more than
15% of the outstanding voting shares of a corporation subject to the statute (an
"Interested  Person") but less than 85% of such shares may not engage in certain
"Business  Combinations" (as defined) with the corporation for a period of three
years  subsequent  to the date on which the  shareholder  became  an  Interested
Person  unless  (i)  prior to such  date the  corporation's  board of  directors
approved  either  the  Business  Combination  or the  transaction  in which  the
shareholder became an Interested Person or (ii) the Business Combination

                                      -75-


is approved by the corporation's  board of directors and authorized by a vote of
at least two-thirds of the outstanding voting stock of the corporation not owned
by the Interested Person.

         The Delaware  Takeover Statute defines the term "Business  Combination"
to include a wide variety of transactions with or caused by an Interested Person
in which the Interested Person receives or could receive a benefit on other than
a pro rata basis with  other  shareholders,  including  mergers,  certain  asset
sales,  certain  issuances  of  additional  shares  to  the  Interested  Person,
transactions with the corporation  which increase the proportionate  interest of
the Interested  Person or transactions  in which the Interested  Person receives
certain other benefits.

         Connecticut   Regulatory   Restrictions   on   Acquisitions  of  Stock.
Connecticut  banking  statutes  prohibit any person from  directly or indirectly
offering to acquire or acquiring voting stock of a Connecticut-chartered savings
bank (such as Derby),  a federal  savings  bank having its  principal  office in
Connecticut (such as Webster Bank) or a holding company of any such entity (such
as Webster or DS Bancor), that would result in such person becoming, directly or
indirectly,  the beneficial  owner of more than 10% of any class of voting stock
of such entity unless such person had previously filed an acquisition  statement
with the  Connecticut  Commissioner  and such offer or acquisition  has not been
disapproved by the Connecticut Commissioner.

         Federal Law. Federal law provides that, subject to certain  exemptions,
no person  acting  directly or  indirectly  or through or in concert with one or
more other persons may acquire  "control" of an insured  institution  or holding
company thereof,  without giving at least 60 days prior written notice providing
specified  information to the appropriate  federal banking agency (i.e., the OTS
in the case of Webster  and  Webster  Bank and the FDIC in the case of DS Bancor
and  Derby).  "Control"  is defined for this  purpose as the power,  directly or
indirectly, to direct the management or policies of an insured institution or to
vote  25  percent  or more of any  class  of  voting  securities  of an  insured
institution.  Control is presumed to exist where the acquiring  party has voting
control  of at  least  10  percent  of any  class  of the  institution's  voting
securities  which is  registered  under  Section 12 of the  Exchange  Act and is
actively traded. The term "actively traded" is defined in the regulation to mean
securities  that are either  listed on a  securities  exchange  or quoted on The
Nasdaq National Market.  The OTS or FDIC may prohibit the acquisition of control
if it finds, among  other  things, that (i) the  acquisition  would  result in a
monopoly or substantially  lessen  competition;  (ii) the financial condition of
the  acquiring   person  might   jeopardize  the  financial   stability  of  the
institution;  or (iii) the competence,  experience or integrity of any acquiring
person or any of the proposed  management  personnel indicates that it would not
be in the interest of the depositors or the public to permit the  acquisition of
control by such person.

                  ADJOURNMENT OF DS BANCOR AND WEBSTER MEETINGS

         The  holders of DS Bancor  Common  Stock will be asked to  approve,  if
necessary,  the adjournment of the DS Bancor Meeting to solicit further votes in
favor of the Merger  Agreement.  The  proxies of DS Bancor  shareholders  voting
against the Merger  Agreement  may not be used by management to vote in favor of
an adjournment pursuant to its discretionary authority.

         The  holders  of Webster  Common  Stock  will be asked to  approve,  if
necessary,  the  adjournment of the Webster  Meeting to solicit further votes in
favor of the issuance of additional  Webster Common Stock in connection with the
Merger  Agreement.  The  proxies  of Webster  shareholders  voting  against  the
issuance  may not be used to vote in favor  of an  adjournment  pursuant  to its
discretionary authority.

                              SHAREHOLDER PROPOSALS

         Any proposal which a Webster stockholder wishes to have included in the
proxy materials of Webster with respect to Webster's 1997 Annual Meeting must be
received by Webster at Webster's  principal  executive offices at Webster Plaza,
Waterbury, Connecticut 06702 no later than November 24, 1996.

         If the Merger  Agreement  is  approved  and  adopted  and the Merger is
consummated,  there will not be an annual meeting of DS Bancor's shareholders in
1997. However, if the merger is not consummated,  DS Bancor anticipates that its
1997  annual  meeting  will be held in  April,  1997.  Therefore,  any  proposal
intended to be presented by a DS Bancor shareholder for inclusion in DS Bancor's
proxy statement for its 1997 annual meeting must be received by DS Bancor at its
principal executive office no later than November 29, 1996.

                                  OTHER MATTERS

         It is not expected that any matters other than those  described in this
Joint Proxy Statement/Prospectus will be brought before the DS Bancor Meeting or
the Webster  Meeting.  If any other matters are  presented,  however,  it is the
intention of the persons  named in the DS Bancor proxy and the Webster  proxy to
vote such proxy in accordance with the  determination of a majority of the Board
of  Directors  of  DS  Bancor  and  Webster,  respectively,  including,  without
limitation,  a motion to adjourn or  postpone  the DS Bancor  Meeting to another
time and/or place for the purpose of soliciting  additional  proxies in order to
approve the Merger  Agreement or  otherwise  and a motion to adjourn or postpone
the Webster  Meeting to another time and/or place for the purpose of  soliciting
additional proxies in order to approve the issuance of additional Webster Common
Stock in connection with the Merger Agreement or otherwise.


                                     EXPERTS

         The consolidated  financial  statements of Webster at December 31, 1995
and 1994,  and for each of the years in the three year period ended December 31,
1995,  incorporated by reference into the Registration  Statement,  have been so
incorporated  in reliance upon the report of KPMG Peat Marwick LLP,  independent
certified  public  accountants,  incorporated  herein by reference  and upon the
authority of said firm as experts in accounting and auditing.  The report refers
to the fact that Webster changed its method of accounting for mortgage servicing
rights in 1995 and income taxes in 1993.

         The consolidated financial statements of DS Bancor at December 31, 1995
and 1994, and for each of the years in the three-year  period ended December 31,
1995, incorporated by reference into this Joint Proxy Statement/Prospectus, have
been so  incorporated  in reliance  upon the report of  Friedberg,  Smith & Co.,
P.C., independent certified public accountants, incorporated herein by reference
and upon the authority of that firm as experts in accounting and auditing.


                                  LEGAL MATTERS

         The  validity  of the Webster  Common  Stock to be issued in the Merger
has been passed upon by Hogan & Hartson L.L.P.,  Washington,  D.C. Fried, Frank,
Harris, Shriver & Jacobson and Mintz, Levin, Cohn, Ferris, Glovsky & Popeo, P.C.
have passed upon certain tax matters in connection with the Merger.

The Board of Directors of
DS Bancor, Inc.
33 Elizabeth Street
Derby, CT  06418


Dear Lady and Gentlemen:

                  You have  requested  our  opinion as to the  fairness,  from a
financial point of view, of the  consideration to be received by shareholders of
DS Bancor, Inc. (the "Company") from Webster Financial  Corporation  ("Webster")
pursuant  to  the  Agreement   and  Plan  of  Merger  among  Webster   Financial
Corporation,  Webster Acquisition Corp., and DS Bancor, Inc. dated as of October
7, 1996 (the  "Agreement").  Pursuant  to the  Agreement,  each  share of Common
Stock,  par value $1.00 per share, of DS Bancor ("DS Bancor Common Stock") shall
be converted into and  exchangeable  for that number of shares of Webster Common
Stock, par value $0.01 per share ("Webster Common Stock") determined by dividing
$43.00 by the Base  Period  Trading  Price (as  defined in the  Agreement)  (the
"Exchange Ratio"), provided,  however, if the Base Period Trading Price shall be
greater than $38.50,  the Exchange  Ratio shall be 1.11688;  provided,  further,
however,  if the Base  Period  Trading  Price  shall be less  than  $31.50,  the
Exchange Ratio shall be 1.36508;  provided,  further, if the Base Period Trading
Price shall be less than $28.00,  the Agreement may be terminated by the Company
unless  Webster  elects  that the  Exchange  Ratio  shall be equal to the number
resulting  from  dividing  $38.22 by the Base Period  Trading Price (the "Merger
Consideration").

                  Alex.  Brown & Sons  Incorporated,  as a customary part of its
investment banking business, is engaged in the valuation of businesses and their
securities   in   connection   with   mergers   and   acquisitions,   negotiated
underwritings, private placements and valuations for estate, corporate and other
purposes.  We have acted as  financial  advisor to the Board of Directors of the
Company in connection with the  transactions  described above and will receive a
fee for our  services,  a significant  portion of which is  contingent  upon the
consummation of the DS Bancor, Inc.  transaction  contemplated by the Agreement.
Alex. Brown & Sons Incorporated  regularly  publishes research reports regarding
the financial  services  industry and the  businesses and securities of publicly
owned companies in that industry.

                  In  connection  with this opinion,  we have  reviewed  certain
publicly available financial information  concerning the Company and Webster and
certain internal financial analyses and other information furnished to us by the
Company and Webster.  We have also held  discussions  with members of the senior
management  of the Company and Webster  regarding  the business and prospects of
the Company and Webster,  respectively.  In  addition,  we have (i) reviewed the
reported  price and  trading  activity  for DS Bancor  Common  Stock and Webster
Common Stock, (ii) compared

certain  financial  and stock  market  information  for the Company and Webster,
respectively,  with similar  information for certain comparable  companies whose
securities  are publicly  traded,  (iii) reviewed the Agreement and compared the
financial  terms  of  the  Agreement  with  those  of  certain  recent  business
combinations  of other  savings  banks  and  commercial  banks  which we  deemed
comparable  in whole  or in part  and (iv)  performed  such  other  studies  and
analyses and considered such other factors as we deemed appropriate.

                  We have not independently  verified the information  described
above and for purposes of this opinion have assumed the  accuracy,  completeness
and fairness thereof.  With respect to information  relating to the prospects of
the Company and Webster, we have assumed that such information reflects the best
currently  available  estimates and judgments of the  managements of the Company
and Webster,  respectively, as to the likely future financial performance of the
Company and Webster. In addition, we have not made an independent  evaluation or
appraisal of the assets or  liabilities  of the Company or Webster,  nor have we
been  furnished with any such  evaluation or appraisal.  Our opinion is based on
market,  economic and other  conditions as they exist and can be evaluated as of
the date of this letter.

                  Based upon and  subject to the  foregoing,  it is our  opinion
that, as of the date of this letter,  the Merger  Consideration  is fair, from a
financial point of view, to the holders of DS Bancor Common Stock.

                               Very truly yours,


                               ALEX. BROWN & SONS INCORPORATED

                                 October 6, 1996



Board of Directors
Webster Financial Corporation
Webster Plaza, 145 Bank Street
Waterbury, CT  06720

Members of the Board:

         Webster Financial  Corporation (the "Company") and DS Bancor, Inc. (the
"Subject  Company")  propose to enter into an  agreement  dated as of October 7,
1996 (the  "Agreement"),  pursuant to which the Subject  Company  will be merged
with and  into  the  Company  in a  transaction  (the  "Merger")  in which  each
outstanding  share of the Subject  Company's  common stock (the "Subject Company
Shares") will be converted,  as more fully described in the Agreement,  into the
right to  receive a number of shares of common  stock of the  Company  ("Company
Shares") equal to the Exchange Ratio (as determined  pursuant to the Agreement).
The terms and conditions of the Merger are more fully set forth in the Agreement
and certain related agreements.

         You have asked us whether,  in our opinion,  the Exchange Ratio is fair
to the Company from a financial point of view.

         In  arriving  at the  opinion  set forth  below,  we have,  among other

                  management   of  the  Company  and  of  the  Subject   Company

                  earnings,  assets and prospects of the Company and the Subject
                  Company and their  respective view as to the future  financial
                  performance  of the  Company,  the  Subject  Company  and  the
                  combined entity, as the case may be, following the Merger;


         (5)      Reviewed the historical market prices and trading activity for
                  the Subject Company Shares and the Company Shares and compared

                  as prepared,  and discussed  with us, by senior  management of
                  the Company and the Subject Company;

         (9)      Considered,  based  upon  information  provided  by the senior
                  management  of the Company and the  Subject  Company,  the pro
                  forma  effects of the Merger on the  Company's  capitalization
                  ratios and  projected  earnings,  book and tangible book value
                  per share;

         (10)     Reviewed a October 4, 1996 draft of the Agreement; and

         (11)     Reviewed  such  other  financial   studies  and  analyses  and
                  performed such other investigations and took into account such
                  other matters as we deemed  necessary to the rendering of this
                  opinion.

         In preparing our opinion,  we have assumed and relied upon the accuracy
and  completeness of all financial and other  information  supplied or otherwise
made available to us for purposes of this opinion, and we have not independently
verified such  information or undertaken an independent  evaluation or appraisal
of the assets or liabilities  of the Company or the Subject  Company nor have we
been  furnished  any such  evaluation  or  appraisal.  We are not experts in the
evaluation  of allowance  for loan losses,  and we have not made an  independent
evaluation of the adequacy of the  allowances  for loan losses of the Company or
the Subject  Company nor have we reviewed any  individual  credit files,  and we
have assumed that the aggregate allowance for loan losses of the Company and the
Subject  Company is  adequate to cover such losses and will be adequate on a pro
forma basis for the  combined  entity.  We have also assumed and relied upon the
senior management of the Company referred to above as to the  reasonableness and
achievability of the financial and operating  forecasts (and the assumptions and
bases  therefore)  provided to, and  discussed  with,  us by the Company and the
Subject  Company.  In that  regard,  we have assumed with your consent that such
information,  including, without limitation, financial forecasts, projected cost
savings  and  operating  synergies  resulting  from the Merger  and  projections
regarding  underperforming  and  nonperforming  assets,  net  charge-offs,   and
adequacy  of  reserves,  reflect  the best  currently  available  estimates  and
judgment of the senior  management of the Company and the Subject  Company as to
the expected future financial  performance of the Company,  the Subject Company,
and the combined entity, as the case may be. Our opinion is necessarily based on
economic,  market and other conditions as in effect on, and the information made
available to us as of, the date hereof.

         Our opinion has been rendered  without  regard to the necessity for, or
level of, any restrictions,  obligations, undertakings or divestitures which may
be imposed or required in the course of obtaining  regulatory  approvals for the
merger.

         We have been  retained by the Board of  Directors  of the Company as an
independent  contractor to act as financial  advisor to the Company with respect
to the Merger and will receive a

                                      B-2


fee for our  services.  We have  within  the past two years  provided  financial
advisory,  investment  banking and other  services  to the Company and  received
customary fees for the rendering of such services.  In addition, in the ordinary
course of our  securities  business,  we may actively  trade debt and/or  equity
securities  of  the  Company  and  the  Subject  Company  and  their  respective
affiliates  for our  own  account  and the  accounts  of our  customers,  and we
therefore  may  from  time  to  time  hold a long  or  short  position  in  such
securities.

         Our opinion is directed  to the Board of  Directors  of the Company and
does not constitute,  nor shall it be deemed to constitute,  a recommendation to
any  stockholder  of the Company as to how such  stockholder  should vote at any
stockholder  meeting  of the  Company  that may be held in  connection  with the
Merger. This opinion is directed only to the Exchange Ratio.

         On the basis of, and  subject to the  foregoing,  we are of the opinion
that  the  Exchange  Ratio,  taken  as a whole,  is fair to the  Company  from a
financial point of view.

                               Very truly yours,

                               MERRILL LYNCH, PIERCE, FENNER

Item 20. Indemnification of Directors and Officers.

         Section 145 of the Delaware General  Corporation Law sets forth certain
circumstances  under  which  directors,  officers,  employees  and agents may be
indemnified  against  liability  that they may incur in their  capacity as such.
Section 145 of the Delaware  General  Corporation Law, which is filed as Exhibit
99.1 to this Registration Statement, is incorporated herein by reference.

         Article Nine of the Registrant's By-laws,  entitled  "Indemnification,"
provides for indemnification of the Registrant's directors,  officers, employees
and  agents  under  certain  circumstances.  Article  Nine  of the  Registrant's
By-laws,  which are filed as  Exhibit  4.1 to this  Registration  Statement,  is
incorporated herein by reference.

         The Registrant also has the power to purchase and maintain insurance on
behalf of its directors and officers.  The  Registrant has in effect a policy of
liability insurance covering its directors and officers,  the effect of which is
to reimburse  the  directors  and  officers of the  Registrant  against  certain
damages and expenses  resulting  from certain claims made against them caused by
their negligent act, error or omission.

         The foregoing  indemnity and  insurance  provisions  have the effect of
reducing  directors'  and officers'  exposure to personal  liability for actions
taken in connection with their respective positions.

         Insofar as indemnification for liabilities arising under the Securities
Act of 1933 may be permitted to directors,  officers and controlling  persons of
the  Registrant  pursuant  to  the  foregoing  provisions,   or  otherwise,  the
Registrant  has been advised that in the opinion of the  Securities and Exchange
Commission  such  indemnification  is against  public policy as expressed in the
Securities Act and is, therefore,  unenforceable.  In the event that a claim for
indemnification  against such liabilities  (other than payment by the Registrant
of expenses incurred or paid by a director, officer or controlling person of the
Registrant  in the  successful  defense of any action,  suit or  proceeding)  is
asserted by such director,  officer or controlling person in connection with the
securities being  registered,  the Registrant will, unless in the opinion of its
counsel the matter has been settled by controlling precedent,  submit to a court
of appropriate  jurisdiction the question whether such  indemnification by it is
against  public  policy as expressed in the  Securities  Act of 1933 and will be
governed by the final adjudication of such issue.

Item 22. Undertakings.

     (a)  The undersigned Registrant hereby undertakes:

          (1)  To file,  during  any  period in which  offers or sales are being
               made, a post-effective amendment to this registration statement:

               (i)  To include any  prospectus  required by Section  10(a)(3) of
                    the Securities Act of 1933;

               (ii) To reflect  in the  prospectus  any facts or events  arising
                    after the effective date of the  registration  statement (or
                    the most recent  post-effective  amendment  thereof)  which,
                    individually  or in the  aggregate,  represent a fundamental
                    change  in the  information  set  forth in the  registration
                    statement;

                                      II-2




              (iii) To include any material information with respect to the plan
                    of distribution not previously disclosed in the registration
                    statement or any material change to such  information in the
                    registration statement.

          (2)  That,  for the purpose of  determining  any  liability  under the
               Securities Act of 1933, each such post-effective  amendment shall
               be  deemed to be a new  registration  statement  relating  to the
               securities  offered therein,  and the offering of such securities
               at that time shall be deemed to be the initial bona fide offering
               thereof.

          (3)  To  remove  from   registration  by  means  of  a  post-effective
               amendment any of the  securities  being  registered  which remain
               unsold at the termination of the offering.

     (b)  The undersigned  Registrant  hereby  undertakes  that, for purposes of
          determining  any  liability  under the  Securities  Act of 1933,  each
          filing of the Registrant's  annual report pursuant to section 13(a) or
          section 15(d) of the Exchange Act of 1934 (and, where applicable, each
          filing of an employee benefit plan's annual report pursuant to section
          15(d) of the Exchange Act of 1934) that is  incorporated  by reference
          in the registration statement shall be deemed to be a new registration
          statement relating to the securities offered therein, and the offering
          of such securities at that time shall be deemed to be the initial bona
          fide offering thereof.

     (c)  The undersigned Registrant hereby undertakes as follows: that prior to
          any public reoffering of the securities  registered  hereunder through
          use of a prospectus which is a part of this registration statement, by
          any  person or party who is deemed  to be an  underwriter  within  the
          meaning of Rule 145(c),  the issuer  undertakes  that such  reoffering
          prospectus will contain the  information  called for by the applicable
          registration  form with respect to  reofferings  by persons who may be
          deemed underwriters,  in addition to the information called for by the
          other Items of the applicable form.

     (d)  The  Registrant  undertakes  that every  prospectus  (i) that is filed
          pursuant to paragraph (c) immediately preceding, or (ii) that purports
          to meet the requirements of section 10(a)(3) of the Act and is used in
          connection  with an  offering of  securities  subject to Rule 415 (ss.
          230.415 of this  chapter),  will be filed as a part of an amendment to
          the  registration  statement and will not be used until such amendment
          is  effective,  and that,  for purposes of  determining  any liability
          under the Securities Act of 1933, each such  post-effective  amendment
          shall be deemed to be a new  registration  statement  relating  to the
          securities  offered  therein,  and the offering of such  securities at
          that  time  shall be  deemed  to be the  initial  bona  fide  offering
          thereof.

     (e)  The undertaking concerning  indemnification is included as part of the
          response to Item 20.

     (f)  The undersigned  Registrant  hereby  undertakes to respond to requests
          for information  that is incorporated by reference into the prospectus
          pursuant  to  Items 4,  10(b),  11,  or 13 of this  Form,  within  one
          business day of receipt of such request,  and to send the incorporated
          documents  by first class mail or other  equally  prompt  means.  This
          includes  information  contained in documents filed  subsequent to the
          effective  date of the  registration  statement  through  the  date of
          responding to the request.

                                      II-3




     (g)  The undersigned  Registrant  hereby undertakes to supply by means of a
          post-effective amendment all information concerning a transaction, and
          the company being acquired involved therein,  that was not the subject
          of  and  included  in  the  registration   statement  when  it  became
          effective.


                                      II-4
