                                OPTION AGREEMENT


                   THE TRANSFER OF THE OPTION GRANTED BY THIS
                  AGREEMENT IS SUBJECT TO RESALE RESTRICTIONS.


         OPTION  AGREEMENT,  dated as of  October  7, 1996  (this  "Agreement"),
between  DS  BANCOR,  INC.,  a  Delaware  corporation  ("Issuer"),  and  WEBSTER
FINANCIAL CORPORATION, a Delaware corporation ("Grantee").

                                   WITNESSETH:

         WHEREAS,  Grantee and Issuer have entered into an Agreement and Plan of
Merger,  dated as of October 7, 1996 (the  "Plan"),  which was  executed  by the
parties hereto prior to the execution of this Agreement; and

         WHEREAS,  as a condition and inducement to Grantee's  entering into the
Plan and in  consideration  therefor,  Issuer  has agreed to grant  Grantee  the
Option (as defined below).

         NOW,  THEREFORE,  in  consideration  of the  foregoing  and the  mutual
covenants and  agreements  set forth herein and in the Plan,  the parties hereto
agree as follows:

         SECTION  1.  Issuer   hereby   grants  to  Grantee  an   unconditional,
irrevocable  option (the "Option") to purchase,  subject to the terms hereof, up
to 564,296 fully paid and non-assessable shares of Common Stock, par value $1.00
per share of Issuer  ("Issuer Common Stock") (which number of shares is equal to
18.6% of the number of  outstanding  shares of Issuer  Common  Stock on the date
hereof),  at a price per share equal to $36.50 (the "Initial Price");  provided,
however,  that in the event  Issuer  issues  or  agrees to issue any  additional
shares of Issuer  Common  Stock  (other than shares  issued upon the exercise of
options  outstanding  as of the date of the Plan in accordance  with their terms
pursuant to  existing  stock  option  plans),  or grants one or more  options to
purchase  additional  shares of  issuer  common  stock at a price  less than the
Initial Price, as adjusted pursuant to Section 5(b) hereof,  such price shall be
equal to such lesser price (such price, as adjusted,  is hereinafter referred to
as the "Option Price").  The number of shares of Issuer Common Stock that may be
received  upon the  exercise  of the Option and the Option  Price are subject to
adjustment as herein set forth.

         SECTION 2. (a) Grantee may  exercise the Option,  in whole or part,  at
any time and from time to time  following the occurrence of a Purchase Event (as
defined  below);  provided that the Option shall  terminate and be of no further
force and effect upon the earliest to occur of the  following  events (which are
collectively referred to as an "Exercise Termination Event"):

                        (i) The time immediately prior to the Effective Time;

                       (ii) 12 months  after the first  occurrence of a Purchase
         Event,

                      (iii)  18  months  after  the   termination  of  the  Plan
         following the  occurrence of a Preliminary  Purchase  Event (as defined
         below), unless clause (vii) is applicable;

                       (iv)  upon  the  termination  of the  Plan,  prior to the
         occurrence of a Purchase Event or  Preliminary  Purchase  Event,  by DS
         Bancor pursuant to Section 8.1(h) of the Plan, both parties pursuant to
         Section  8.1(a) of the Plan, by either party pursuant to Section 8.1(b)
         or (c) of the Plan or 

                                      E-42



         Section  8.1(d) of the Plan  based on any  required  vote of  Grantee's
         stockholders  not being  received,  or by Issuer  pursuant  to  Section
         8.1(e) or (f) of the Plan;


                        (v) 135 days  after  the  termination  of the  Plan,  by
         either  party  pursuant  to  Section  8.1(d)  of the Plan  based on the
         required  vote of  Issuer's  stockholders  not  being  received,  if no
         Purchase Event or Preliminary  Purchase Event has occurred prior to the
         meeting of stockholders  (or any  adjournment or postponement  thereof)
         held to vote on the Plan;

                       (vi) nine months after the  termination  of the Plan,  by
         Grantee  pursuant  to  Section  8.1(e) or (f)  thereof as a result of a
         breach by Issuer, unless such breach was willful or intentional; or

                      (vii) 24 months  after  the  termination  of the Plan,  by
         Grantee  pursuant  to  Section  8.1(e) or (f)  thereof as a result of a
         willful or  intentional  breach by Issuer,  or by Grantee  pursuant  to
         Section 8.1(g) of the Plan.

                  (b) The term  "Preliminary  Purchase  Event" shall mean any of
the following  events or transactions  occurring on or after the date hereof and
prior to an Exercise Termination Event:

                           (i) Issuer without having  received  Grantee's  prior
         written  consent,  shall  have  entered  into any  letter  of intent or
         definitive  agreement  to  engage  in an  Acquisition  Transaction  (as
         defined below) with any person (as defined below) other than Grantee or
         any of its subsidiaries  (each a "Grantee  Subsidiary") or the Board of
         Directors of Issuer shall have  recommended  that the  shareholders  of
         Issuer approve or accept any  Acquisition  Transaction  with any Person
         (as the term  "person" is defined in Section  3(a)9 and 13(d)(3) of the
         Securities  Exchange Act of 1934 (the "Exchange Act") and the rules and
         regulations  thereunder) other than Grantee or any Grantee  Subsidiary.
         For purposes of this Agreement "Acquisition Transaction" shall mean (x)
         a merger, consolidation or other business combination involving Issuer,
         (y) a purchase,  lease or other acquisition of all or substantially all
         of the assets of Issuer, (z) a purchase or other acquisition (including
         by way of  merger.  consolidation,  share  exchange  or  otherwise)  of
         Beneficial Ownership (as the term "beneficial  ownership" is defined in
         Regulation 13d-3(a) of the Exchange Act) of securities representing 15%
         or  more  of  the  voting  power  of  Issuer;  provided,  however  that
         "Acquisition  Transaction" shall not include a transaction entered into
         after the  termination of the Plan in which the Issuer is the surviving
         entity,  if in connection  with such  transaction,  no person  acquires
         Beneficial Ownership of 15 percent or more of the total voting power of
         the Issuer to be  outstanding  after giving effect to such  transaction
         and in which  the  aggregate  voting  power of Issuer  acquired  by all
         persons is less than 25 percent of the total voting power of Issuer;

                           (ii) Any Person  (other  than  Grantee,  any  Grantee
         Subsidiary  or any current  affiliate  of Issuer)  shall have  acquired
         Beneficial Ownership of 15% or more of the outstanding shares of Issuer
         Common Stock;

                           (iii)  (a) Any  Person  (other  than  Grantee  or any
         Grantee  Subsidiary) shall have made a bona fide proposal to Issuer or,
         by a public  announcement or written  communication  that is or becomes
         the subject of public disclosure, to Issuer's shareholders to engage in
         an  Acquisition   Transaction  (including,   without  limitation,   any
         situation  in which  any  Person  other  than  Grantee  or any  Grantee
         Subsidiary  shall have commenced (as such term is defined in Rule 14d-2
         under the Exchange Act), or shall have filled a registration  statement
         under the  Securities Act of 1933, as amended (the  "Securities  Act"),
         with respect to a tender offer or exchange offer to purchase any shares
         of Issuer Common Stock such that, upon consummation of such offer, such
         person  would  have  Beneficial  Ownership  of 15% or more of the  then
         outstanding shares of Issuer Common Stock (such an offer being referred
         to herein as a "Tender  Offer" or an "Exchange  Offer",  respectively))
         (b)  such  bona  fide   proposal  is  not   withdrawn  or  such  public
         announcement or written communication is not publicly withdrawn and (c)
         stockholders  of Issuer do not approve  the  Merger,  as defined in the
         Plan, at the Special Meeting, as defined in the Plan;

                           (iv)  There  shall  exist a  willful  or  intentional
         breach under the Plan by Issuer and such breach would  entitle  Grantee
         to terminate the Plan;

                                      E-43




                           (v) The special meeting of Issuers' shareholders held
         for the  purpose  of voting  on the  Plan,  shall not have been held or
         shall have been canceled  prior to termination of the Plan, or Issuer's
         Board of  Directors  shall  have  failed to  recommend,  or shall  have
         withdrawn or modified in a manner adverse to Grantee the recommendation
         of Issuer's Board of Directors,  that Issuer's shareholders approve the
         Plan, or if Issuer or Issuer's  Board of Directors  fails to oppose any
         proposal by any Person (other than Grantee or any Grantee  Subsidiary);
         or

                           (vi) Any Person  (other  than  Grantee or any Grantee
         Subsidiary)  shall have filed and have had accepted for  processing (or
         been deemed informationally complete) an application or notice with the
         Office of Thrift  Supervisor (the "OTS") the Federal Deposit  Insurance
         Corporation (the "FDIC"),  the Connecticut  Banking  Commissioner  (the
         "Commissioner"),  or  other  regulatory  or  administrative  agency  or
         commission (each, a "Governmental Authority") for approval to engage in
         an Acquisition Transaction.

                  (c) The term "Purchase  Event" shall mean any of the following
events or  transactions  occurring  on or after the date  hereof and prior to an
Exercise Termination Event:

                           (i) The acquisition by any Person (other than Grantee
         or any  Grantee  Subsidiary)  of  Beneficial  Ownership  (other than on
         behalf of the  Issuer)  of 25% or more of the then  outstanding  Issuer
         Common Stock; or

                           (ii) The  occurrence of a Preliminary  Purchase Event
         described in Section 2(b)(i) except that the percentage  referred to in
         clause (z) thereof shall be 25%.

                  (d) Issuer  shall  notify  Grantee  promptly in writing of the
occurrence of any Preliminary  Purchase Event or Purchase Event known to Issuer;
provided,  however,  that the  giving of such  notice  by Issuer  shall not be a
condition to the right of Grantee to exercise the Option.

                  (e) In the event  that  Grantee is  entitled  to and wishes to
exercise  the  Option,  it shall send to Issuer a written  notice  (the  "Option
Notice"  and the date of which  being  hereinafter  referred  to as the  "Notice
Date")  specifying (i) the total number of shares of Issuer Common Stock it will
purchase  pursuant  to such  exercise  and (ii) the  time  (which  shall be on a
business  day that is not less than three nor more than ten  business  days from
the Notice  Date) on which the  closing of such  purchase  shall take place (the
"Closing  Date");  such  closing  to take place at the  principal  office of the
Issuer;  provided,  that, if prior  notification  to or approval of the OTS, the
FDIC,  the  Commissioner  or any other  Governmental  Authority  is  required in
connection with such purchase (each, a  "Notification"  or an "Approval," as the
case may be), (a) Grantee shall promptly file the required notice or application
for approval ("Notice/Application"), (b) Grantee shall expeditiously process the
Notice/Application  and (c) for the  purpose of  determining  the  Closing  Date
pursuant  to clause  (ii) of this  sentence,  the period of time that  otherwise
would  run from the  Notice  Date  shall  instead  run from the  later of (x) in
connection with any  Notification,  the date on which any required  notification
periods have expired or been terminated and (y) in connection with any Approval,
the date on which such  approval  has been  obtained and any  requisite  waiting
period or periods shall have expired.  For purposes of Section 2(a) hereof,  any
exercise  of the  Option  shall be deemed to occur on the Notice  Date  relating
thereto. On or prior to the Closing Date, Grantee shall have the right to revoke
its  exercise of the Option by written  notice to the Issuer given not less than
three business days prior to the Closing Date.

                  (f) At the closing referred to in Section 2(e) hereof, Grantee
shall pay to Issuer  the  aggregate  purchase  price for the number of shares of
Issuer  Common Stock  specified in the Option  Notice in  immediately  available
funds  by wire  transfer  to a bank  account  designated  by  Issuer;  provided,
however,  that  failure or refusal of Issuer to  designate  such a bank  account
shall not preclude Grantee from exercising the Option.

                  (g) At such  closing,  simultaneously  with  the  delivery  of
immediately  available  funds as provided in Section 2(f)  hereof,  Issuer shall
deliver to Grantee a  certificate  or  certificates  representing  the number of
shares of Issuer Common Stock  specified in the Option Notice and, if the Option
should be exercised in part only, a new Option  evidencing the rights of Grantee
thereof to purchase the balance of the shares of Issuer Common Stock purchasable
hereunder.


                                      E-44


                  (h)  Certificates  for  Issuer  Common  Stock  delivered  at a
closing hereunder shall be endorsed with a restrictive  legend  substantially as
follows:

                  The transfer of the shares  represented by this certificate is
         subject to resale  restrictions  arising  under the  Securities  Act of
         1933, as amended,  and applicable  state securities laws and to certain
         provisions  of an  agreement  between  DS  Bancor,  Inc.,  and  Webster
         Financial  Corporation,  dated as of October  7,  1996.  A copy of such
         agreement is on file at the principal  office of DS Bancor,  Inc.,  and
         will be provided to the holder hereof without charge upon receipt by DS
         Bancor, Inc., of a written request therefor.

It is understood and agreed that:  (i) the reference to the resale  restrictions
of the  Securities  Act in the above  legend  shall be  removed by  delivery  of
substitute certificate(s) without such reference if Grantee shall have delivered
to  Issuer a copy of a letter  from the  staff of the  Securities  and  Exchange
Commission (the "SEC") or Governmental  Authority  responsible for administering
any  applicable  state  securities  laws or an opinion of  counsel,  in form and
substance  satisfactory to Issuer's  counsel,  to the effect that such legend is
not required for purposes of the Securities Act or applicable  state  securities
laws; (ii) the reference to the provisions of this Agreement in the above legend
shall be removed by delivery of substitute certificate(s) without such reference
if the shares have been sold or transferred in compliance with the provisions of
this Agreement and under circumstances that do not require the retention of such
reference;  and  (iii)  the  legend  shall be  removed  in its  entirety  if the
conditions in the preceding clauses (i) and (ii) are both satisfied. In addition
such certificates shall bear any other legend as may be required by law.

                  (i) Upon the giving by  Grantee to Issuer of an Option  Notice
and the tender of the applicable  purchase price in immediately  available funds
on the Closing  Date,  unless  prohibited by  applicable  law,  Grantee shall be
deemed to be the holder of record of the number of shares of Issuer Common Stock
specified in the Option Notice, notwithstanding that the stock transfer books of
Issuer  shall then be closed or that  certificates  representing  such shares of
Issuer  Common Stock shall not then  actually be  delivered  to Grantee.  Issuer
shall pay all expenses and other charges that may be payable in connection  with
the preparation,  issuance and delivery of stock certificates under this Section
2 in the name of Grantee.

                  SECTION 3. Issuer agrees: (i) that it shall at all times until
the  termination  of this Agreement have reserved for issuance upon the exercise
of the Option that number of  authorized  and reserved  shares of Issuer  Common
Stock equal to the maximum  number of shares of Issuer  Common Stock at any time
and from  time to time  issuable  hereunder,  all of  which  shares  will,  upon
issuance  pursuant  hereto,  be duly  authorized,  validly  issued,  fully paid,
non-assessable,  and delivered free and clear of all claims, liens, encumbrances
and security  interests and not subject to any preemptive  rights;  (ii) that it
will  not,  by  amendment  of  its  certificate  of   incorporation  or  through
reorganization,  consolidation, merger, dissolution or sale of assets, or by any
other voluntary act, avoid or seek to avoid the observance or performance of any
of the  covenants,  stipulations  or  conditions  to be  observed  or  performed
hereunder by Issuer;  (iii) promptly to take all  reasonable  action as may from
time to time be requested by the Grantee,  at Grantee's  expense  (including (x)
complying  with  all  premerger  notification,   reporting  and  waiting  period
requirements  specified  in  15  U.S.C.  ss.  18a  and  regulations  promulgated
thereunder and (y)in the event prior approval of or notice to the OTS, the FDIC,
the Commissioner or any other Governmental Authority, under the Home Owners Loan
Act of 1933,  as amended,  the Change in Bank  Control Act of 1978,  as amended,
Section  36a-181 or Section 36a- 184, as  applicable,  of the  Connecticut  Bank
Holding  Company Act, or any other  applicable  federal or state banking law, is
necessary  before the  Option  may be  exercised,  cooperating  with  Grantee in
preparing such  applications  or notices and providing such  information to each
such  Governmental  Authority  as it may  require in order to permit  Grantee to
exercise  the Option and Issuer duly and  effectively  to issue shares of Issuer
Common Stock pursuant  hereto;  and (iv) to take all action  provided  herein to
protect the rights of Grantee against dilution.

                  SECTION 4. This Agreement (and the Option granted  hereby) are
exchangeable,  without expense, at the option of Grantee,  upon presentation and
surrender  of this  Agreement  at the  principal  office  of  Issuer,  for other
agreements providing for Options of different denominations entitling the holder
thereof to purchase, on the same terms and subject to the same conditions as are
set forth  herein- in the  aggregate  the same number of shares of Issuer Common
Stock purchasable  hereunder.  The terms "Agreement" and "Option" as used herein
include any  agreements  and related  options for which this  Agreement (and the
Option  granted  hereby) may 
                                      E-45



be exchanged.  Upon receipt by Issuer of evidence reasonably  satisfactory to it
of the loss,  theft,  destruction or mutilation of this  Agreement,  and (in the
case of loss, theft or destruction) of reasonably satisfactory  indemnification,
and upon surrender and cancellation of this Agreement, if mutilated, Issuer will
execute and deliver a new Agreement of like tenor and date.


                  SECTION  5. The  number  of  shares  of  Issuer  Common  Stock
purchasable  upon the exercise of the Option shall be subject to adjustment from
time to time as follows:

                           (a) In the event of any  change in the type or number
         of  shares  of  Issuer  Common  Stock by  reason  of  stock  dividends,
         split-ups,  mergers,  recapitalizations,   combinations,  subdivisions,
         conversions,  exchanges  of shares  or other  issuances  of  additional
         shares  (other than  pursuant to the exercise of the Option),  the type
         and number of shares of Issuer Common Stock  purchasable  upon exercise
         hereof shall be  appropriately  adjusted and proper  provision shall be
         made so that, in the event that any additional  shares of Issuer Common
         Stock are to be issued or otherwise  become  outstanding as a result of
         any such change (other than pursuant to an exercise of the Option), the
         number of shares of Issuer  Common  Stock  that  remain  subject to the
         Option shall be increased or decreased (as  applicable) so that,  after
         such   issuance  and  together  with  shares  of  Issuer  Common  Stock
         previously  issued  pursuant to the exercise of the Option (as adjusted
         on account of any of the foregoing changes in the Issuer Common Stock),
         the Option  shall equal 18.6% of the number of shares of Issuer  Common
         Stock then issued and outstanding.

                           (b)  Whenever  the number of shares of Issuer  Common
         Stock  purchasable upon exercise hereof is adjusted as provided in this
         Section 5, the Option Price shall be adjusted by multiplying the Option
         Price by a  fraction,  the  numerator  of  which  shall be equal to the
         number  of  shares  of Issuer  Common  Stock  purchasable  prior to the
         adjustment and the denominator of which shall be equal to the number of
         shares of Issuer Common Stock purchasable after the adjustment.

                  SECTION 6. (a) Upon the  occurrence  of a Purchase  Event that
occurs prior to an Exercise  Termination Event,  Issuer shall, at the request of
Grantee (whether on its own behalf or on behalf of any subsequent  holder of the
Option (or part  thereof) or of any of the shares of Issuer  Common Stock issued
pursuant hereto),  promptly prepare,  file and keep current a shelf registration
statement  under the  Securities  Act  covering  any shares  issued and issuable
pursuant to the Option and shall use its  reasonable  best efforts to cause such
registration statement to become effective,  and to remain current and effective
for a period not in excess of 180 days from the day such registration  statement
first becomes effective, in order to permit the sale or other disposition of any
shares of Issuer  Common  Stock  issued  upon total or partial  exercise  of the
Option ("Option Shares") in accordance with any plan of disposition requested by
Grantee.  Grantee  shall  have the right to demand one such  registration  which
right shall not be transferable except to an affiliate of Grantee. Grantee shall
provide all  information  reasonably  requested  by Issuer for  inclusion in any
registration  statement  to be  filed  hereunder.  In  connection  with any such
registration,  Issuer and Grantee shall provide each other with representations,
warranties,  indemnities and other  agreements  customarily  given in connection
with  such  registration.  If  requested  by  Grantee  in  connection  with such
registration,  Issuer  and  Grantee  shall  become a party  to any  underwriting
agreement  relating  to the  sale of such  shares,  but  only to the  extent  of
obligating themselves in respect of representations, warranties, indemnities and
other  agreements   customarily   included  in  such  underwriting   agreements.
Notwithstanding  the foregoing,  if Grantee revokes any exercise notice or fails
to exercise any Option with respect to any exercise  notice  pursuant to Section
2(e) hereof,  Issuer shall not be obligated to continue any registration process
with  respect to the sale of Option  Shares  issuable  upon the exercise of such
Option and Grantee shall not be deemed to have demanded  registration  of Option
Shares.

                  (b) In the  event  that  Grantee  requests  Issuer  to  file a
registration  statement following the failure to obtain any approval required to
exercise the Option as described in Section 9 hereof, the closing of the sale or
other  disposition  of the Issuer Common Stock or other  securities  pursuant to
such registration  statement shall occur  substantially  simultaneously with the
exercise of the Option.

                  (c) Concurrently  with the filing of a registration  statement
under Section 6(a) hereof, Issuer shall also make all filings required to comply
with state  securities  laws in such number of states as Grantee may  reasonably
request.


                                      E-46



                  SECTION 7. (a) Upon the  occurrence  of a Purchase  Event that
occurs prior to an Exercise  Termination  Event, (i) at the request (the date of
such request  being the "Option  Repurchase  Request  Date") of Grantee,  Issuer
shall  repurchase,  subject to compliance  with  applicable law and out of funds
legally  available  therefor,  the Option from  Grantee at a price (the  "Option
Repurchase  Price") equal to the amount by which (A) the market/offer  price (as
defined below) exceeds (B) the Option Price,  multiplied by the number of shares
for which the Option may then be exercised  and (ii) at the request (the date of
such request being the "Option Share  Repurchase  Request Date") of the owner of
Option  Shares from time to time (the  "Owner"),  Issuer shall  repurchase  such
number of the Option  Shares  from the Owner as the Owner shall  designate  at a
price (the "Option  Share  Repurchase  Price") equal to the  market/offer  price
multiplied by the number of Option Shares so designated.  The term "market/offer
price" shall mean the highest of (i) the price per share of Issuer  Common Stock
at which a tender offer or exchange  offer therefor has been made after the date
hereof and on or prior to the Option Repurchase Request Date or the Option Share
Repurchase  Request Date, as the case may be, (ii) the price per share of Issuer
Common Stock paid or to be paid by any third party pursuant to an agreement with
Issuer  (whether  by way of a merger,  consolidation  or  otherwise),  (iii) the
average of the 20 highest last sale prices for shares of Issuer  Common Stock as
reported within the 90-day period ending on the Option  Repurchase  Request Date
or the Option Share Repurchase Request Date, as the case may be, and (iv) in the
event of a sale of all or substantially  all of Issuer's assets,  the sum of the
price paid in such sale for such  assets  and the  current  market  value of the
remaining assets of Issuer as determined by an investment  banking firm selected
by Grantee  or the  Owner,  as the case may be,  and  reasonably  acceptable  to
Issuer,  divided by the number of shares of Issuer Common Stock  outstanding  at
the time of such sale.  In  determining  the  market/offer  price,  the value of
consideration  other than cash shall be the value  determined  by an  investment
banking  firm  selected  by  Grantee  or the  Owner,  as the  case  may be,  and
reasonably  acceptable to Issuer.  The investment  banking firm's  determination
shall be conclusive and binding on all parties.  For purposes of this Section 7,
Purchase  Event shall have the true  meaning as set forth in Section 2(c) hereof
except that in both  subclause (i) and (ii) the  applicable  percentage of stock
shall be 50% rather than 25%.

                  (b) Grantee or the Owner, as the case may be, may exercise its
right to  require  Issuer to  repurchase  the Option  and/or  any Option  Shares
pursuant to this Section 7 by  surrendering  for such purpose to Issuer,  at its
principal office, a copy of this Agreement or certificates for Option Shares, as
applicable,  accompanied by a written notice or notices  stating that Grantee or
the Owner, as the case may be, elects to require Issuer to repurchase the Option
and/or the Option Shares in accordance with the provisions of this Section 7. As
promptly as  practicable,  and in any event  within 30  business  days after the
surrender of the Option and/or  certificates  representing Option Shares and the
receipt of such notice or notices  relating  thereto,  Issuer  shall  deliver or
cause to be delivered to Grantee the Option Repurchase Price or to the Owner the
Option Share Repurchase Price.

                  (c)  Issuer  hereby  undertakes  to use  its  reasonable  best
efforts to obtain all required  regulatory,  shareholder and legal approvals and
to file any required  notices as promptly as  practicable in order to accomplish
any repurchase  contemplated by this Section 7. Nonetheless,  to the extent that
Issuer is prohibited under applicable law or regulation,  or as a consequence of
the provision as to "well capitalized" in Section 7(a) hereof, from repurchasing
any Option  and/or any Option  Shares in full,  Issuer shall  promptly so notify
Grantee and/or the Owner and thereafter  deliver or cause to be delivered,  from
time to time, to Grantee and/or the Owner,  as  appropriate,  the portion of the
Option  Repurchase  Price and the Option Share Repurchase  Price,  respectively,
that it is no longer prohibited from delivering, within five business days after
the date on which Issuer is no longer so prohibited;  provided, however, that if
Issuer at any time after delivery of a notice of repurchase  pursuant to Section
7(b)  hereof is  prohibited  as referred to above,  from  delivering  to Grantee
and/or the Owner,  as  appropriate,  the Option  Repurchase  Price or the Option
Share  Repurchase  Price,  respectively,  in  full,  Grantee  or the  Owner,  as
appropriate,  may revoke its  notice of  repurchase  of the Option or the Option
Shares  either in whole or in part  whereupon,  in the case of a  revocation  in
part,  Issuer  shall  promptly  (i)  deliver  to Grantee  and/or  the Owner,  as
appropriate.  that  portion of the  Option  Purchase  Price or the Option  Share
Repurchase Price that Issuer is not prohibited from delivering after taking into
account any such  revocation  and (ii) deliver,  as  appropriate,  either (A) to
Grantee, a new Agreement evidencing the right of Grantee to purchase that number
of shares of Issuer  Common Stock equal to the number of shares of Issuer Common
Stock purchasable  immediately prior to the delivery of the notice of repurchase
less the number of shares of Issuer  Common Stock  covered by the portion of the
Option  repurchased or, (B) to the Owner, a certificate for the number of Option
Shares covered by the revocation.

                                      E-47



                  (d) Issuer shall not enter into any agreement  with any Person
(other than  Grantee or a Grantee  Subsidiary)  for an  Acquisition  Transaction
unless the other Person assumes all the  obligations of Issuer  pursuant to this
Section 7 in the event that Grantee or the Owner elects, in its sole discretion,
to require such other Person to perform such obligations.

                  (e) Notwithstanding  the foregoing  provisions of this Section
7, Issuer  shall not be required to deliver or cause to be  delivered to Grantee
the Option Repurchase Price or to the Owner the Option Share Repurchase Price to
the  extent  that  such  delivery  would  prevent  the  Acquisition  Transaction
described  in  Section  2(b)(1)  from  being  accounted  for as a  "poolings  of
interest,"  as  determined  by Issuer's  independent  accountants.  Issuer shall
advise  Grantee or the Owner  within 15 business  days after  either  Grantee or
Owner requests  information  from Issuer as to whether,  and to the extent that,
Issuer intends to rely upon this Section 7(e) to preclude  Grantee or Owner from
otherwise exercising their rights under this Section 7.

                  SECTION  8.  (a)  In  the  event  that  prior  to an  Exercise
Termination  Event,  Issuer  shall  enter into a letter of intent or  definitive
agreement (i) to  consolidate  or merge with any Person (other than Grantee or a
Grantee  Subsidiary),  and  Issuer  shall  not be the  continuing  or  surviving
corporation of such  consolidation  or merger,  (ii) to permit any Person (other
than Grantee or a Grantee  Subsidiary) to merge into Issuer, and Issuer shall be
the continuing or surviving  corporation,  but, in connection  with such merger.
the then  outstanding  shares of Issuer  Common  Stock shall be changed  into or
exchanged for stock or other securities of any other Person or cash or any other
property or the then outstanding  shares of Issuer Common Stock shall 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 Person  (other than Grantee or a Grantee
Subsidiary)  then,  and in each such case,  such letter of intent or  definitive
agreement  governing such  transaction  shall make proper  provision so that the
Option shall,  upon the  consummation of such transaction and upon the terms and
conditions set forth herein, be converted into, or exchanged for, an option (the
"Substitute  Option"),  at the election of Grantee,  of either (x) the Acquiring
Corporation  (as defined  below) or (y) any person that  controls the  Acquiring
Corporation  (the Acquiring  Corporation and any such  controlling  person being
hereinafter referred to as the "Substitute Option Issuer").

                  (b) The Substitute Option shall be exercisable for such number
of shares of Substitute Common Stock (as is hereinafter  defined) as is equal to
the market/offer price (as defined in Section 7 hereof) multiplied by the number
of  shares  of  Issuer  Common  Stock  for  which  the  Option  was  theretofore
exercisable, divided by the Average Price (as hereinafter defined). The exercise
price of the  Substitute  Option per share of the  Substitute  Common Stock (the
"Substitute  Purchase Price") shall then be equal to the Option Price multiplied
by a fraction in which the  numerator  is the number of shares of Issuer  Common
Stock for which the Option was  theretofore  exercisable  and the denominator is
the number of shares for which the Substitute Option is exercisable.

                  (c) The Substitute  Option shall otherwise have the same terms
as the Option,  provided that if the terms of the Substitute Option cannot,  for
legal  reasons,  be the same as the  Option,  such terms  shall be as similar as
possible and in no event less  advantageous to Grantee,  provided,  further that
the terms of the  Substitute  Option  shall  include  (by way of example and not
limitation)   provisions  for  the  repurchase  of  the  Substitute  Option  and
Substitute  Common Stock by the  Substitute  Option Issuer on the same terms and
conditions as provided in Section 7 hereof.

                  (d)      The following terms have the meanings indicated:

                           (i)  "Acquiring   Corporation"  shall  mean  (i)  the
         continuing or surviving  corporation of a consolidation  or merger with
         Issuer (if other than Issuer),  (ii) Issuer in a merger in which Issuer
         is the continuing or surviving corporation, and (iii) the transferee of
         all or any substantial part of Issuer's assets.

                          (ii) "Substitute  Common Stock" shall mean  the common
         stock  issued by the  Substitute  Option  Issuer  upon  exercise of the
         Substitute Option.

                         (iii) "Average  Price" shall  mean  the average closing
         price of a share of  Substitute  Common Stock for the  one-year  period
         immediately  preceding the  consolidation,  merger or sale in

                                      E-48



         question.  but in no event higher than the closing  price of the shares
         of  Substitute  Common Stock on the day preceding  such  consolidation,
         merger or sale; provided that if Issuer is the issuer of the Substitute
         Option,  the Average Price shall be computed with respect to a share of
         Issuer  Common Stock  issued by Issuer,  the  corporation  merging into
         Issuer  or by any  company  which  controls  or is  controlled  by such
         merging corporation, as Grantee may elect.

                  (e) In no event,  pursuant to any of the foregoing paragraphs,
shall the Substitute  Option be exercisable for more than 19.9% of the aggregate
of the shares of Substitute  Common Stock  outstanding  immediately prior to the
issuance of the Substitute Option. In the event that the Substitute Option would
be exercisable  for more than 19.9% of the aggregate of the shares of Substitute
Common Stock but for this clause (e), the Substitute  Option Issuer shall make a
cash payment to Grantee  equal to the excess of (i) the value of the  Substitute
Option  without giving effect to the limitation in this clause (e) over (ii) the
value of the  Substitute  Option after giving  effect to the  limitation in this
clause  (e).  This  difference  in value  shall be  determined  by a  nationally
recognized investment banking firm selected by Grantee and the Substitute Option
Issuer.  In addition,  the  provisions of Section 5(a) hereof shall not apply to
the issuance of any Substitute  Option and for purposes of applying Section 5(a)
hereof thereafter to any Substitute Option the percentage referred to in Section
5(a) hereof shall  thereafter  equal the  percentage  that the percentage of the
shares of Substitute  Common Stock subject to the Substitute Option bears to the
number of shares of Substitute Common Stock outstanding.

                  SECTION  9.  Notwithstanding  Sections  2, 6 and 7 hereof,  if
Grantee has given the notice  referred to in one or more of such  Sections,  the
exercise of the rights  specified in any such  Section  shall be extended (a) if
the exercise of such rights requires obtaining  regulatory  approvals (including
any required  waiting  periods) to the extent necessary to obtain all regulatory
approvals  for the exercise of such rights,  and (b) to the extent  necessary to
avoid  liability  under  Section  16(b) of the  Exchange  Act by  reason of such
exercise;  provided  that in no event shall any closing  date occur more than 12
months after the related  notice  date,  and, if the closing date shall not have
occurred  within such period due to the failure to obtain any required  approval
by the OTS,  the FDIC,  the  Commissioner  or any other  Governmental  Authority
despite the best efforts of Issuer or the Substitute  Option Issuer, as the case
may be, to obtain such approvals,  the exercise of the rights shall be deemed to
have been  rescinded  as of the related  notice  date.  In the event (a) Grantee
receives official notice that an approval of the OTS, the FDIC. the Commissioner
or any other  Governmental  Authority  required for the purchase and sale of the
Option  Shares  will not be issued  or  granted  or (b) a  closing  date has not
occurred  within 12 months  after the related  notice date due to the failure to
obtain any such  required  approval,  Grantee  shall be entitled to exercise the
Option in connection with the concurrent resale of the Option Shares pursuant to
a registration  statement as provided in Section 6 hereof.  Nothing contained in
this  Agreement  shall restrict  Grantee from  specifying  alternative  means of
exercising  rights  pursuant to  Sections  2,6 or 7 hereof in the event that the
exercising  of any such  rights  shall not have  occurred  due to the failure to
obtain any required approval referred to in this Section 9.

                  SECTION 10. Issuer hereby  represents  and warrants to Grantee
as follows:

                  (a) Issuer has the requisite  corporate power and authority to
execute  and  deliver  this  Agreement  and  to  consummate   the   transactions
contemplated  hereby.  The  execution  and  delivery of this  Agreement  and the
consummation of the transactions  contemplated hereby have been duly approved by
the Board of Directors of Issuer and no other corporate  proceedings on the part
of Issuer are  necessary  to  authorize  this  Agreement  or to  consummate  the
transactions  so  contemplated.  This  Agreement  has  been  duly  executed  and
delivered  by,  and  constitutes  a valid and  binding  obligation  of,  Issuer,
enforceable against Issuer in accordance with its terms, subject to any required
Governmental  Approval,  and except as enforceability  thereof may be limited by
applicable bankruptcy, insolvency, reorganization,  moratorium and other similar
laws affecting the  enforcement of creditors'  rights  generally and except that
the availability of the equitable  remedy of specific  performance or injunctive
relief is subject to the discretion of the court before which any proceeding may
be brought.

                  (b)  Issuer  has  taken  all  necessary  corporate  action  to
authorize and reserve and to permit it to issue,  and at all times from the date
hereof through the  termination  of this Agreement in accordance  with its terms
will have reserved for issuance upon the exercise of the Option,  that number of
shares of Issuer  Common  Stock equal to the maximum  number of shares of Issuer
Common Stock at any time and from time to time issuable hereunder,  and all such
shares, upon issuance pursuant hereto, will be duly authorized,  validly issued,


                                      E-49



fully paid, non-assessable,  and will be delivered free and clear of all claims,
liens,  encumbrances  and security  interests and not subject to any  preemptive
rights.

                  SECTION 11. (a)  Neither of the parties  hereto may assign any
of its rights or delegate  any of its  obligations  under this  Agreement or the
Option created hereunder to any other Person without the express written consent
of the other party,  except that  Grantee may assign this  Agreement to a wholly
owned subsidiary of Grantee and Grantee may assign its rights hereunder in whole
or in part  after the  occurrence  of a  Preliminary  Purchase  Event.  The term
"Grantee" as used in this  Agreement  shall also be deemed to refer to Grantee's
permitted assigns.

                  (b) Any  assignment  of rights  of  Grantee  to any  permitted
assignee of Grantee hereunder shall bear the restrictive legend at the beginning
thereof substantially as follows:

                  The transfer of the option  represented by this assignment and
         the related option agreement is subject to resale restrictions  arising
         under the  Securities  Act of 1933, as amended,  and  applicable  state
         securities  laws and to certain  provisions of an agreement  between DS
         Bancor, Inc., and Webster Financial  Corporation dated as of October 7,
         1996. A copy of such agreement is on file at the principal office of DS
         Bancor,  Inc.,  and will be provided to any  permitted  assignee of the
         Option without charge upon receipt of a written request therefor.

                  SECTION 12. Each of Grantee and Issuer will use its reasonable
efforts to make all filings with,  and to obtain  consents of, all third parties
and Governmental  Authorities  necessary to the consummation of the transactions
contemplated by this Agreement,  including, without limitation,  applying to the
OTS,  the FDIC,  the  Commissioner  and any  other  Governmental  Authority  for
approval to acquire the shares issuable hereunder.

                  SECTION 13. The parties hereto  acknowledge that damages would
be an  inadequate  remedy for a breach of this  Agreement by either party hereto
and that the  obligations  of the parties  hereto shall be enforceable by either
party hereto through injunctive or other equitable relief.  Both parties further
agree to waive  any  requirement  for the  securing  or  posting  of any bond in
connection  with  the  obtaining  of any such  equitable  relief  and that  this
provision is without  prejudice to any other rights that the parties  hereto may
have for any failure to perform this Agreement.

                  SECTION 14. If any term,  provision,  covenant or  restriction
contained in this Agreement is held by a court or a federal or state  regulatory
agency of  competent  jurisdiction  to be invalid,  void or  unenforceable,  the
remainder of the terms,  provisions and covenants and restrictions  contained in
this  Agreement  shall  remain in full force and effect,  and shall in no way be
affected,  impaired or  invalidated.  If for any reason such court or regulatory
agency  determines  that Grantee is not  permitted to acquire,  or Issuer is not
permitted to repurchase  pursuant to Section 7 hereof, the full number of shares
of Issuer  Common Stock  provided in Section  1(a) hereof (as adjusted  pursuant
hereto), it is the express intention of Issuer to allow Grantee to acquire or to
require Issuer to repurchase  such lesser number of shares as may be permissible
without any amendment or modification hereof.

                  SECTION 15. All notices,  requests,  claims, demands and other
communications  hereunder shall be deemed to have been duly given when delivered
in person, by cable. telegram,  telecopy or telex, or by registered or certified
mail (postage prepaid,  return receipt requested) at the respective addresses of
the parties set forth in the Plan.

                  SECTION 16. This Agreement,  the rights and obligations of the
parties hereto, and any claims or disputes relating thereto shall be governed by
and  construed  in  accordance  with the laws of the State of Delaware  (but not
including the choice of law rules thereof).

                  SECTION 17. This  Agreement  may be executed in  counterparts,
each of  which  shall  be  deemed  to be an  original,  but all of  which  shall
constitute  one and the same  agreement  and shall be  effective  at the time of
execution and delivery.


                                      E-50



                  SECTION 18.  Except as otherwise  expressly  provided  herein,
each of the parties hereto shall bear and pay all costs and expenses incurred by
it or on its behalf in connection with the transactions contemplated hereunder.

                  SECTION 19. Except as otherwise  expressly  provided herein or
in the Plan, this Agreement  contains the entire  agreement  between the parties
with respect to the transactions contemplated hereunder and supersedes all prior
arrangements or understandings with respect thereof,  written or oral. The terms
and  conditions of this  Agreement  shall inure to the benefit of and be binding
upon the parties hereto and their respective  successors and permitted  assigns.
Nothing in this Agreement,  expressed or implied, is intended to confer upon any
party, other than the parties hereto, and their respective  successors except as
assigns, any rights, remedies,  obligations or liabilities under or by reason of
this Agreement, except as expressly provided herein.

                  SECTION 20.  Capitalized  terms used in this Agreement and not
defined herein but defined in the Plan shall have the meanings  assigned thereto
in the Plan.

                  SECTION  21.  Nothing  contained  in this  Agreement  shall be
deemed to authorize or require  Issuer or Grantee to breach any provision of the
Plan or any provision of law applicable to the Grantee or Issuer.

                  SECTION 22. In the event that any  selection or  determination
is to be  made  by  Grantee  or the  Owner  hereunder  and at the  time  of such
selection  or  determination  there is more  than one  Grantee  or  Owner,  such
selection shall be made by a majority in interest of such Grantees or Owners.

                  SECTION  23. In the  event of any  exercise  of the  option by
Grantee,  Issuer and such Grantee shall execute and deliver all other  documents
and  instruments  and take all other action that may be reasonably  necessary in
order to consummate the transactions provided for by such exercise.

                  SECTION 24. Except to the extent Grantee exercises the Option,
Grantee  shall  have no rights to vote or  receive  dividends  or have any other
rights as a  shareholder  with respect to shares of Issuer  Common Stock covered
hereby.


                                      E-51






                  IN WITNESS WHEREOF, each of the parties has caused this Option
Agreement to be executed and delivered on its behalf by their officers thereunto
duly authorized, all as of the date first above written.
