                          MARITIME BANK & TRUST COMPANY

                              STOCKHOLDER AGREEMENT


     This STOCKHOLDER  AGREEMENT,  dated as of November 3, 1998, is entered into
by and among Webster Financial Corporation,  a Delaware corporation ("Webster"),
and  the 10  stockholders  of  Maritime  Bank &  Trust  Company,  a  Connecticut
chartered bank ("Maritime Bank"), named on Schedule I hereto (collectively,  the
"Stockholders"),  who are the  directors  (including  the  President  and  Chief
Executive  Officer) of Maritime Bank and the only  "affiliates" (for purposes of
Rule 145 under the  Securities  Act of 1933,  as amended) of Maritime Bank other
than the executive officers of Maritime Bank.

     WHEREAS,  Webster,  Webster  Bank,  a wholly  owned  subsidiary  of Webster
("Webster  Bank"),  and Maritime Bank have entered into an Agreement and Plan of
Merger, dated as of the date hereof (the "Agreement"), which is conditioned upon
the execution of this Stockholder  Agreement and which provides for, among other
things,  the  acquisition  of Maritime  Bank by  Webster,  to be effected by the
merger  of  Maritime  Bank  with and into  Webster  Bank,  in a  stock-for-stock
transaction (the "Merger"); and

     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 Maritime Bank;

     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 MARITIME BANK COMMON STOCK.  Each Stockholder  represents
and warrants that the number of shares of Maritime Bank common stock,  par value
$.67  per  share  ("Maritime  Bank  Common  Stock"),  set  forth  opposite  such
Stockholder's  name on  Schedule  I hereto  is the  total  number  of  shares of
Maritime  Bank Common  Stock over which such person has  "beneficial  ownership"
within the meaning of Rule 13d-3 under the  Securities  Exchange Act of 1934, as
amended,  except that the provisions of Rule 13d-3(d)(1)(i)  shall be considered
without any limit as to time.

     2.   AGREEMENTS OF THE STOCKHOLDERS.  Each Stockholder covenants and agrees
that:

          (a) Such Stockholder  shall, at any meeting of the holders of Maritime
Bank Common Stock  called for the purpose,  vote or cause to be voted all shares
of Maritime Bank Common Stock in which such  Stockholder  has the sole or shared
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  Maritime
Bank is to be acquired by or merged  with,  or pursuant to which  Maritime  Bank
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).

          (b) 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 Maritime Bank Common Stock over which
such stockholder has sole or shared dispositive power;  provided,  however, that
this Section 2(b) shall not apply to a pledge existing as of October 20, 1998.

          (c) Such Stockholder shall not in his/her capacity as a stockholder of
Maritime Bank 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 all
or substantially  all of the assets or liabilities not in the ordinary course of
business,  sale of shares of  capital  stock or  similar  transaction  involving
Maritime  Bank.  Nothing  herein  shall  impair  such  Stockholder's   fiduciary
obligations as a director of Maritime Bank.

          (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 the Agreement.

          (e) Such  Stockholder  shall  comply with all  applicable  federal and
state  securities laws in connection with any sale of Webster common stock,  par
value $.01 per share ("Webster  Common Stock") received in exchange for Maritime
Bank Common 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.

          (f) Except as set forth in the attached  Schedule II, such Stockholder
has no present plan or intent, and as of the effective time of the Merger, shall
have no present plan or intent, to engage in a sale,  exchange,  transfer (other
than  an  intrafamily  gift),   distribution  (including  a  distribution  by  a
corporation to its  shareholders),  redemption,  or reduction in any way of such
Stockholder's risk of ownership by short sale or otherwise, or other disposition
(not including a bona fide pledge), directly or indirectly,  with respect to any
of the shares of Webster  Common Stock to be received by such  Stockholder  upon
the Merger (except for cash received for fractional shares).

     3.   TERMINATION.  The  parties  agree and  intend  that  this  Stockholder
Agreement  is 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 the 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 holders of Maritime  Bank Common  Stock fail to
approve the Agreement or Maritime Bank 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 Maritime Bank 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,  except upon  consummation of such
plan or proposal.

     4.   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 the addresses set forth at Schedule I.

     5.   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.

     6.   COUNTERPARTS.  This  Stockholder  Agreement  may be executed in one or
more  counterparts,  all of which shall be considered one and the same agreement
and each of which shall be deemed an original,  and shall become  effective when
counterparts  have been signed by each of the parties and delivered to the other
party, it being understood that all parties need not sign the same counterpart.

                                       2



     7.   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.

     8.   REGULATORY  APPROVAL.  If any provision of this Stockholder  Agreement
requires the approval of any  regulatory  authority in order to be  enforceable,
then such  provision  shall not be  effective  until such  approval is obtained;
provided, however, that the foregoing shall not affect the enforceability of any
other provision of this Stockholder Agreement.
