Exhibit 2.3





                              STOCKHOLDER AGREEMENT


                  This  STOCKHOLDER  AGREEMENT,  dated as of October 7, 1996, is
entered into by and among Webster Financial Corporation ("Webster"),  a Delaware
corporation,  and the thirteen  stockholders of DS Bancor, Inc. ("DS Bancor"), a
Delaware   corporation,   named  on   Schedule   I  hereto   (collectively   the
"Stockholders"), who are directors or executive officers of DS Bancor.

                  WHEREAS,  Webster,  Webster  Acquisition Corp., a wholly-owned
subsidiary  of  Webster  ("Merger  Sub")  and DS  Bancor  have  entered  into an
Agreement and Plan of Merger, dated as of October ___, 1996 ("Agreement"), which
is conditioned upon the concurrent  execution of this Stockholder  Agreement and
which provides for,  among other things,  the merger of Merger Sub with and into
DS Bancor,  in a  stock-for-stock  transaction  pursuant to which DS Bancor will
become a wholly-owned subsidiary of Webster (the "Merger");

                  WHEREAS  in order to induce  Webster  to enter into or proceed
with the Agreement, each of the Stockholders agrees to, among other things, vote
in favor of the Agreement, the Merger and the other transactions contemplated by
the Agreement in his/her capacity as a stockholder of DS Bancor;

                  NOW,  THEREFORE in consideration  of the premises,  the mutual
covenants  and   agreements  set  forth  herein  and  other  good  and  valuable
consideration,  the  sufficiency  of which is hereby  acknowledged,  the parties
hereto agree as follows:

         1. Ownership of DS Bancor Common Stock. Each Stockholder represents and
warrants  that  he/she has or shares the right to vote and dispose of the number
of shares of common  stock of DS Bancor,  par value  $1.00 per share ("DS Bancor
Stock"), set forth opposite such Stockholder's name on Schedule I hereto.

         2.  Agreements  of the  Stockholders.  Each  Stockholder  covenants and
agrees that:

                  (a)  Such  Stockholder  shall,  at any  meeting  of DS  Bancor
         stockholders  called  for the  purpose,  vote or cause to be voted  all
         shares of DS Bancor  Stock in which such  Stockholder  has the right to
         vote (whether owned as of the date hereof or hereafter acquired) (i) in
         favor  of  the  Agreement,   the  Merger  and  the  other  transactions
         contemplated  by the  Agreement  and (ii)  against any plan or proposal
         pursuant  to which DS Bancor is to be acquired  by or merged  with,  or
         pursuant to which DS Bancor proposes to sell all or  substantially  all
         of its assets and  liabilities  to, any person,  entity or group (other
         than Webster or any affiliate  thereof)  unless the Board of Directors,
         following  receipt  of written  advice of DS  Bancor's  legal  counsel,
         reasonably determines,  that voting against said 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
         stockholders.

         (b) Except as otherwise  expressly  permitted hereby,  such Stockholder
shall not, prior to the consummation of the Merger or the earlier termination of
this Stockholder Agreement in accordance with its terms, sell, pledge,  transfer
or otherwise  dispose of his/her shares of DS Bancor Stock;  provided,  however,
that,  this Section 2(b) shall not apply (i) to a pledge existing as of the date

                                      E-53



of this  Agreement,  (ii) to a sale,  pledge,  transfer or other  disposition of
shares  of DS Bancor  Stock  acquired  subsequent  to the date  hereof  upon the
exercise of options under the DS Bancor Stock Option Plan by a  Stockholder  who
is an executive officer of DS Bancor, if, in the case of (i), or (ii) such sale,
pledge,  transfer  or  other  disposition  occurs  no  later  than  the 31st day
preceding the consummation of the Merger. To enable  Stockholders to comply with
the foregoing  provision,  Webster will notify the Stockholders at least 45 days
in  advance  of the  date  that  Webster  anticipates  that the  Merger  will be
consummated.


         (c) Such Stockholder  shall not in his/her capacity as a stockholder of
DS Bancor  directly or indirectly  encourage or solicit or hold  discussions  or
negotiations  with, or provide any information  to, any person,  entity or group
(other than  Webster or an affiliate  thereof)  concerning  any merger,  sale of
substantial  assets or liabilities not in the ordinary course of business,  sale
of shares of capital stock or similar transaction  involving DS Bancor.  Nothing
herein shall impair such Stockholders' fiduciary obligations as a director of DS
Bancor.

         (d) Such Stockholder shall use his/her best efforts to take or cause to
be taken all action, and to do or cause to be done all things necessary,  proper
or advisable  under  applicable  laws and  regulations  to  consummate  and make
effective the Merger contemplated by this Stockholder Agreement.

         (e) Such Stockholder  shall not, prior to the public release by Webster
of an  earnings  report  to its  stockholders  covering  at least  one  month of
operations  after  consummation of the Merger (the "Restricted  Period"),  sell,
pledge (other than the  replacement  of an existing  pledge of DS Bancor Stock),
transfer or otherwise  dispose of the shares of Webster  Stock to be received by
him/her for his/her shares of DS Bancor Stock upon  consummation  of the Merger;
it being agreed that  Webster  shall cause such  earnings  report to be publicly
released  within 30 days after the end of the first  month of  operations  after
consummation of the Merger.

         (f) Such Stockholder shall comply with all applicable federal and state
securities  laws in  connection  with  any sale of  Webster  Stock  received  in
exchange  for DS Bancor  Stock in the Merger,  including  the trading and volume
limitations as to sales by affiliates contained in Rule 145 under the Securities
Act of 1933, as amended.

         (g) Such Stockholder shall not sell or otherwise dispose of a number of
shares of his DS Bancor Common Stock or, during the Restricted  Period shares of
Webster  Common Stock which are  exchanged  for said shares (i) which is greater
than 10% of his total beneficial  ownership of said shares as of the date of the
first  such sale (ii)  which in the  aggregate  with  shares  sold or  otherwise
disposed of by all other  Stockholders will be greater than 1% of the issued and
outstanding  shares  of DS Bancor as of the date of the  first  such  sale.  For
purposes of this  computation,  outstanding  stock  options that  currently  are
exercisable would be considered as outstanding or beneficially  owned after such
options are  converted to common  stock  equivalents  using the  treasury  stock
method in accordance with generally accepted accounting principles.

         3. Successors and Assigns. A Stockholder may sell, pledge,  transfer or
otherwise  dispose  of his/her  shares of DS Bancor  Stock,  provided  that such
Stockholder  obtains prior  written  consent of Webster and that any acquiror of
such DS Bancor Stock agree in writing to be bound by this Stockholder Agreement.

         4.  Termination.  The parties  agree and intend  that this  Stockholder
Agreement  be a valid and  binding  agreement  enforceable  against  the parties
hereto  and that  damages  and  other  remedies  at law for the  breach  of this
Stockholder  Agreement  are  inadequate.   This  Stockholder  Agreement  may  be
terminated at any time prior to the consummation of the Merger by mutual written
consent of the parties hereto and shall be automatically terminated in the event
that the  Agreement  is  terminated  in  accordance  with its  terms;  provided,
however,  that if the DS Bancor 

                                      E-54




stockholders  fail  to  approve  the  Agreement  or DS  Bancor  fails  to hold a
stockholders meeting to vote on the Agreement, then (i) Section 2(a) clause (ii)
hereof shall continue in effect as to any plan or proposal received by DS Bancor
from any person,  entity or group (other than Webster or any affiliate  thereof)
prior  to the  termination  of the  Agreement  or  within  135 days  after  such
termination  and (ii) Section 2(b) hereof shall continue in effect to preclude a
sale other than  pursuant to normal  brokers  transactions  on the Nasdaq  Stock
Market,  pledge other than to a bona fide  financial  institution  or recognized
securities dealer,  transfer, or other disposition directly or indirectly to any
such  person,  entity or group in  connection  with any such  plan or  proposal,
except upon consummation of such plan or proposal.

         5. Notices.  Notices may be provided to Webster and the Stockholders in
the manner  specified  in the  Agreement,  with all notices to the  Stockholders
being provided to them at DS Bancor in the manner specified in such section.

         6. Governing Law. This  Stockholder  Agreement shall be governed by the
laws of the  State of  Delaware,  without  giving  effect to the  principles  of
conflicts of laws thereof.

         7. Counterparts.  This Stockholder  Agreement may be executed in one or
more counterparts, all of which shall be considered one and the same and each of
which shall be deemed an original.

         8. Headings.  The Section  headings  contained herein are for reference
purposes only and shall not affect in any way the meaning or  interpretation  of
this Stockholder Agreement.

         9. Regulatory Approval. If any provision of this Agreement requires the
approval  of any  regulatory  authority  in order to be  enforceable,  then such
provision  shall not be affective  until such  approval is  obtained;  provided,
however,  that the foregoing  shall not affect the  enforceability  of any other
provision of this Agreement.

         10.  Pooling of Interest.  In the event that Webster elects to have the
Merger  accounted  for as a purchase  rather  than a pooling of  interest,  this
Agreement shall be modified to the extent that restrictions contained herein are
based only on requirements for a pooling of interest.

                                      E-55





         IN WITNESS WHEREOF,  Webster, by a duly authorized officer, and each of
the  Stockholders  have caused this  Stockholder  Agreement  to be executed  and
delivered as of the day and year first above written.
