EXHIBIT 2.2

                                OPTION AGREEMENT


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


                  This  OPTION  AGREEMENT,  dated as of  December  1, 1999 (this
"Agreement"),  is entered  into  between MECH  FINANCIAL,  INC.,  a  Connecticut
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 December 1, 1999 (the "Plan"), which was executed by
the parties thereto 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 994,150 fully paid and nonassessable  shares common stock, par value $.01 per
share of Issuer  ("Issuer  Common  Stock")  (which  number of shares is equal to
19.99% of the total number of  outstanding  shares of Issuer Common Stock on the
date  hereof),  at a price per  share  equal to $34.50  (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,  however, 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) 12   months   after   the   termination  of   the   Plan
         following the  occurrence of a Preliminary  Purchase  Event (as defined
         below), unless clause (vii) of this Section 2(a) is applicable;




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

                  (v)   18 months 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 shareholders not being received;

                  (vi)  18 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)
         or (i) 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 or any of its subsidiaries  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,  as  amended  (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,   acquisition,
         consolidation  or other business  combination  involving  Issuer or any
         subsidiary of Issuer, (y) a purchase, lease or other acquisition of all
         or  substantially  all of the  assets of Issuer  or any  subsidiary  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 10.0% 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 10.0% 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
         15% 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 10.0% 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  10.0%  or  more  of  the  then
         outstanding shares of Issuer Common Stock (such an offer being referred
         to

                                     - 2 -




         herein  as  a  "Tender Offer" or an "Exchange  Offer",  respectively)),
         and (b) the  shareholders  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;

                  (v)   The special  meeting  of Issuers'  shareholders held for
         the purpose of voting on the Plan shall not have been held  pursuant to
         the Plan or shall have been canceled  prior to termination of the Plan,
         or for  any  reason  whatsoever  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 an  application  or notice with the  Board
         of Governors of the Federal Reserve System  (the  "FRB"),  the  Federal
         Deposit Insurance Corporation (the "FDIC"), the   Connecticut   Banking
         Commissioner  (the  "Connecticut  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;

                  (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%; or

                  (iii) 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) or (i) of
         the Plan.

                  (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," 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 10 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,  however,  that, if prior  notification to or approval of the
OTS, the FDIC, the FRB, the Connecticut  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

                                     - 3 -




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.

                  (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 Webster  Financial  Corporation and
         MECH  Financial,  Inc.,  dated as of December  1, 1999.  A copy of such
         agreement  is on file at the  principal  office  of  Webster  Financial
         Corporation,  and will be provided to the holder hereof  without charge
         upon  receipt by Webster  Financial  Corporation  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.

                                     - 4 -




         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)  that it will seek any  necessary  shareholder  approval  that is
necessary to exercise the Option; (iv) 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 FRB, the Connecticut Commissioner or any other Governmental Authority,
under the Change in Bank  Control  Act of 1978,  as  amended,  the Bank  Holding
Company Act, as amended,  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 (v) 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 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 the
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  the sum of 19.9% of the total 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

                                     - 5 -




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
with the SEC,  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 one year 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 four such  registrations  which
right shall be  transferable.  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  statement,  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  preparation  and  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.

         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

                                     - 6 -



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.

                  (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 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.

                  (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.

         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

                                     - 7 -



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  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 19.99% 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 such  number of  shares of  Substitute  Common  Stock but for this


                                     - 8 -



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 FRB, the Connecticut  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 FRB, the
Connecticut  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,
fully paid, non-assessable,  and will

                                     - 9 -



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
         Webster  Financial  Corporation and MECH Financial,  Inc.,  dated as of
         December 1, 1999. A copy of such  agreement is on file at the principal
         office of Webster  Financial  Corporation,  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 FRB, the Connecticut  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 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 the manner and 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).

                                     - 10 -




         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.

         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.

                            [SIGNATURE PAGE FOLLOWS]

                  IN WITNESS WHEREOF, each of the parties has caused this Option
Agreement  to be  executed  and  delivered  on its  behalf  by their  respective
