                             STOCK OPTION AGREEMENT

      STOCK OPTION AGREEMENT,  dated as of April 25, 2000,  between HUDSON RIVER
BANCORP, INC., a Delaware corporation  ("Grantee"),  and COHOES BANCORP, INC., a
Delaware corporation ("Issuer").

                              W I T N E S S E T H:

      WHEREAS,  Grantee and Issuer have entered  into an  Agreement  and Plan of
Merger on even date herewith (the "Merger Agreement");

      WHEREAS,  as a condition  and an  inducement  to Grantee to enter into the
Merger Agreement,  Issuer has agreed to grant Grantee the Option (as hereinafter
defined); and

      WHEREAS, the Board of Directors of Issuer has approved the grant
of the Option and the Merger Agreement;

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

      1. (a)  Issuer  hereby  grants to Grantee  an  unconditional,  irrevocable
option  (the  "Option")  to  purchase,  subject  to the terms  hereof,  up to an
aggregate of 1,574,538 fully paid and nonassessable  shares of the common stock,
par value $.01 per  share,  of Issuer  ("Common  Stock") at a price per share of
$9.8125(the  "Option  Price");  provided,  that in no event  shall the number of
shares  for which  this  Option is  exercisable  exceed  19.9% of the issued and
outstanding shares of Common Stock,  without giving effect to any shares subject
to or issued  pursuant to the Option.  The number of shares of Common Stock that
may be received upon the exercise of the Option and the Option Price are subject
to adjustment as herein set forth.

      (b) In the event that any additional  shares of Common Stock are issued or
otherwise  become  outstanding  after  the date of this  Agreement  (other  than
pursuant to this  Agreement  and pursuant to an event  described in Section 5(a)
hereof),  the number of shares of Common  Stock  subject to the Option  shall be
increased so that, after such issuance,  such number together with any shares of
Common Stock previously  issued pursuant  hereto,  equals 19.9% of the number of
shares of Common Stock then issued and outstanding  without giving effect to any
shares  subject or issued  pursuant to the  Option.  Nothing  contained  in this
Section l(b) or elsewhere in this Agreement shall be deemed to authorize  Issuer
to issue shares to others in breach of any provision of the Merger Agreement.

      2. (a) The Holder (as  hereinafter  defined) may  exercise the Option,  in
whole or part, and from time to time, if, but only if,

                                        1





both an Initial  Triggering  Event (as  hereinafter  defined)  and a  Subsequent
Triggering  Event (as  hereinafter  defined)  shall have  occurred  prior to the
occurrence of an Exercise Termination Event (as hereinafter  defined),  provided
that the Holder shall have sent the written notice of such exercise (as provided
in  subsection  (e) of this  Section 2) within six  months  following  the first
Subsequent  Triggering  Event to occur  (or such  later  period as  provided  in
Section 10). Each of the following shall be an Exercise  Termination  Event: (i)
the Effective Time (as defined in the Merger Agreement); (ii) termination of the
Merger  Agreement in accordance with the provisions  thereof if such termination
occurs  prior  to the  occurrence  of an  Initial  Triggering  Event,  except  a
termination by Grantee  pursuant to Section 8.1(b) of the Merger Agreement where
the  breach by Issuer  giving  rise to the  termination  was  willful (a "Listed
Termination");  or (iii) the  passage  of 12 months  (or such  longer  period as
provided  in  Section  10) after  termination  of the Merger  Agreement  if such
termination  follows the occurrence of an Initial  Triggering  Event or a Listed
Termination  (provided  that if an  Initial  Triggering  Event  occurs  prior to
termination of the Merger  Agreement and continues  beyond such  termination and
prior to the passage of such 12-month  period,  or an Initial  Triggering  Event
occurs  after a Listed  Termination  and prior to the  passage  of such 12 month
period,  then in either case the Exercise  Termination  Event shall be 12 months
from the expiration of the Last Triggering Event (as hereinafter defined) but in
no event more than 18 months after such Merger Agreement termination). The "Last
Triggering  Event" shall mean the last Initial  Triggering Event to expire.  The
term  "Holder"  shall mean the  holder or  holders of the Option or any  portion
thereof.  Notwithstanding  anything to the contrary contained herein, the Option
may not be exercised at any time when Grantee shall be in willful  breach of the
Merger  Agreement  such that Issuer  shall be entitled to  terminate  the Merger
Agreement  pursuant  to  Section  8.1(b)  thereof  as a result of such a willful
breach.

      (b) The term  "Initial  Triggering  Event" shall mean any of the following
events or transactions occurring on or after the date hereof:

                  (i) Issuer or any of its Significant  Subsidiaries (as defined
      in Rule 1-02 of Regulation S-X  promulgated by the Securities and Exchange
      Commission (the "SEC")) (an "Issuer Subsidiary"),  without having received
      Grantee's prior written  consent,  shall have entered into an agreement to
      engage in an

                                        2





      Acquisition Transaction (as hereinafter defined) with any person (the term
      "person"  for  purposes  of this  Agreement  having the  meaning  assigned
      thereto in Sections 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 of its Subsidiaries (each a "Grantee
      Subsidiary")  or the Board of  Directors  of Issuer (the  "Issuer  Board")
      shall have  recommended  that the shareholders of Issuer approve or accept
      any  Acquisition  Transaction  with any  person  other  than  Grantee or a
      Grantee  Subsidiary.  For  purposes of this  Agreement,  (a)  "Acquisition
      Transaction"  shall  mean (x) a merger or  consolidation,  or any  similar
      transaction,  involving  Issuer  or  any  Issuer  Subsidiary  (other  than
      mergers,  consolidations  or similar  transactions  (i)  involving  solely
      Issuer  and/or  one or  more  wholly-owned  Subsidiaries  of  the  Issuer,
      provided,  any such  transaction  is not entered  into in violation of the
      terms of the Merger  Agreement)  or (ii) in which  shareholders  of Issuer
      immediately  prior to completion of such  transaction  own at least 50% of
      the common stock of Issuer (or the  resulting or surviving  entity in such
      transaction),  provided,  any  such  transaction  is not  entered  into in
      violation of the terms of the Merger Agreement),  (y) a purchase, lease or
      other  acquisition  or  assumption of all or any  substantial  part of the
      assets or deposits of Issuer or any Issuer  Subsidiary,  or (z) a purchase
      or other  acquisition  (including by way of merger,  consolidation,  share
      exchange  or  otherwise)  of  securities  representing  10% or more of the
      voting  power  of  Issuer  or  any  Issuer  Subsidiary  and  (b)  "Grantee
      Subsidiary"  shall mean a subsidiary of Grantee  within the definition set
      forth in Rule 12b-2 under the Exchange Act;

                  (ii)  Any  person,  other  than  the  Grantee  or any  Grantee
      Subsidiary,  shall  have  acquired  beneficial  ownership  or the right to
      acquire  beneficial  ownership of 10% or more of the outstanding shares of
      Common  Stock  (the  term  "beneficial  ownership"  for  purposes  of this
      Agreement  having the  meaning  assigned  thereto in Section  13(d) of the
      Exchange Act, and the rules and regulations thereunder);

                  (iii) It shall have been  publicly  announced  that any person
      (other than Grantee or a Grantee  Subsidiary) shall have made, or publicly
      disclosed  an  intention  to make,  a bona fide  proposal  to engage in an
      Acquisition Transaction;

                  (iv) (x) The Issuer Board,  without having received  Grantee's
      prior written consent, shall have withdrawn or

                                        3





      modified (or publicly  announced  its  intention to withdraw or modify) in
      any manner adverse in any respect to Grantee its  recommendation  that the
      shareholders of Issuer approve the transactions contemplated by the Merger
      Agreement,  (y) Issuer or any Issuer  Subsidiary,  without having received
      Grantee's  prior  written  consent,  shall have  authorized,  recommended,
      proposed (or publicly  announced its intention to authorize,  recommend or
      propose) an agreement  to engage in an  Acquisition  Transaction  with any
      person other than Grantee or a Grantee Subsidiary or (z) Issuer shall have
      provided  information  to or engaged in  negotiations  with a third  party
      relating to a possible Acquisition Transaction.

                  (v) Any person,  other than Grantee or any Grantee Subsidiary,
      shall have filed with the SEC a  registration  statement  or tender  offer
      materials with respect to a potential  exchange or tender offer that would
      constitute  an  Acquisition  Transaction  (or  filed a  preliminary  proxy
      statement   with  the  SEC  with  respect  to  a  potential  vote  by  its
      shareholders  to approve  the  issuance of shares to be offered in such an
      exchange offer);

                  (vi) Issuer  shall have  willfully  breached  any  covenant or
      obligation  contained in the Merger Agreement after an overture is made by
      a third party to Issuer or its  shareholders  to engage in an  Acquisition
      Transaction,  and such breach (y) would  entitle  Grantee to terminate the
      Merger  Agreement  (whether  immediately  or after the giving of notice or
      passage  of time or both) and (z) shall not have been  cured  prior to the
      Notice Date (as defined below); or

                  (vii) Any person, other than Grantee or any Grantee Subsidiary
      and other than in connection with a transaction to which Grantee has given
      its prior written consent,  shall have filed an application or notice with
      any federal or state thrift or bank  regulatory  or  antitrust  authority,
      which application or notice has been accepted for processing, for approval
      to engage in an Acquisition Transaction.

      (c) The term "Subsequent Triggering Event" shall mean any of the following
events or transactions occurring after the date hereof:

                  (i) The  acquisition  by any person (other than Grantee or any
      Grantee  Subsidiary)  of  beneficial  ownership of 25% or more of the then
      outstanding Common Stock; or


                                        4





                  (ii) The occurrence of an Initial  Triggering  Event described
      in  clause  (i) of  subsection  (b) of this  Section  2,  except  that the
      percentage  referred to in clause (z) of the second sentence thereof shall
      be 25%.

      (d) Issuer shall notify  Grantee  promptly in writing of the occurrence of
any  Initial  Triggering  Event or  Subsequent  Triggering  Event  (together,  a
"Triggering  Event"),  it being  understood  that the  giving of such  notice by
Issuer  shall not be a  condition  to the right of the  Holder to  exercise  the
Option.

      (e) In the event the  Holder is  entitled  to and wishes to  exercise  the
Option (or any portion  thereof),  it shall send to Issuer a written notice (the
date of which being herein referred to as the "Notice Date")  specifying (i) the
total  number of shares it will  purchase  pursuant to such  exercise and (ii) a
place and date not earlier than three  business  days nor later than 60 business
days from the Notice Date for the closing of such purchase (the "Closing Date");
provided,  that if  prior  notification  to or  approval  of any  regulatory  or
antitrust agency is required in connection with such purchase,  the Holder shall
promptly file the required  notice or application  for approval,  shall promptly
notify  Issuer of such filing and shall  expeditiously  process the same and the
period of time that  otherwise  would run  pursuant to this  sentence  shall run
instead from the date on which any required notification periods have expired or
been  terminated or such approvals have been obtained and any requisite  waiting
period or periods shall have passed.  Any exercise of the Option shall be deemed
to occur on the  Notice  Date  relating  thereto.  The term  "business  day" for
purposes of this Agreement means any day, excluding  Saturdays,  Sundays and any
other  day that is a legal  holiday  in the  State of New York or a day on which
banking institutions in the State of New York are authorized by law or executive
order to close.

      (f) At the closing  referred to in  subsection  (e) of this Section 2, the
Holder shall (i) pay to Issuer the  aggregate  purchase  price for the shares of
Common Stock  purchased  pursuant to the  exercise of the Option in  immediately
available funds by wire transfer to a bank account designated by Issuer and (ii)
present  and  surrender  this  Agreement  to Issuer at its  principal  executive
offices,  provided that the failure or refusal of the Issuer to designate such a
bank account or accept surrender of this Agreement shall not preclude the Holder
from exercising the Option.


                                        5





      (g) At such  closing,  simultaneously  with the  delivery  of  immediately
available  funds as provided in  subsection  (f) of this Section 2, Issuer shall
deliver to the Holder a certificate or certificates  representing  the number of
shares of Common  Stock  purchased by the Holder and, if the Option is exercised
in part only,  a new  Option  evidencing  the  rights of the  Holder  thereof to
purchase the balance of the shares purchasable  hereunder,  and the Holder shall
deliver to Issuer a copy of this Agreement and a letter agreeing that the Holder
will not offer to sell or  otherwise  dispose  of such  shares in  violation  of
applicable law or the provisions of this Agreement.

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

            "The  transfer  of the shares  represented  by this  certificate  is
      subject to certain  provisions  of an  agreement  between  the  registered
      holder  hereof  and Issuer and to resale  restrictions  arising  under the
      Securities Act of 1933, as amended. A copy of such agreement is on file at
      the  principal  office of Issuer and will be provided to the holder hereof
      without charge upon receipt by Issuer of a written request therefor."

It is understood and agreed that:  (i) the reference to the resale  restrictions
of the Securities Act of 1933, as amended (the  "Securities  Act"), in the above
legend shall be removed by delivery of  substitute  certificate(s)  without such
reference if the Holder  shall have  delivered to Issuer a copy of a letter from
the staff of the SEC, or an opinion of counsel, in form and substance reasonably
satisfactory  to Issuer,  to the effect  that such  legend is not  required  for
purposes of the  Securities  Act; (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 in the opinion
of  counsel  to the  Holder in form and  substance  reasonably  satisfactory  to
Issuer;  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 the  Holder to  Issuer  of the  written  notice of
exercise of the Option provided for under  subsection (e) of this Section 2, the
tender of the applicable purchase price in

                                        6





immediately  available  funds  and the  tender  of a copy of this  Agreement  to
Issuer,  the Holder  shall be deemed,  subject to the  receipt of any  necessary
regulatory  approvals,  to be the holder of record of the shares of Common Stock
issuable upon such  exercise,  notwithstanding  that the stock transfer books of
Issuer  shall then be closed or that  certificates  representing  such shares of
Common Stock shall not then be actually  delivered  to the Holder.  Issuer shall
pay all expenses,  and any and all United States federal,  state and local taxes
and other charges that may be payable in connection with the preparation,  issue
and  delivery  of stock  certificates  under  this  Section 2 in the name of the
Holder or its assignee, transferee or designee.

      3.  Issuer  agrees:  (i) that it shall at all  times  maintain,  free from
preemptive  rights,  sufficient  authorized  but unissued or treasury  shares of
Common   Stock  so  that  the  Option  may  be  exercised   without   additional
authorization  of  Common  Stock  after  giving  effect  to all  other  options,
warrants, convertible securities and other rights to purchase Common Stock; (ii)
that it will not, by charter amendment 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  action  as may  from  time  to  time be  required
(including  without  limitation  (x)  complying  with all  applicable  premerger
notification,  reporting and waiting period requirements  specified in 15 U.S.C.
Section 18a and regulations  promulgated  thereunder and (y) in the event, under
any state or federal  thrift or banking law,  prior approval of or notice to any
state or federal  regulatory  authority  is  necessary  before the Option may be
exercised,  cooperating  fully with the Holder in preparing such applications or
notices  and  providing  such  information  to such state or federal  regulatory
authority  as they may  require) in order to permit the Holder to  exercise  the
Option and Issuer duly and  effectively to issue shares of Common Stock pursuant
hereto;  and (iv)  promptly  to take all action  provided  herein to protect the
rights of the Holder against dilution.

      4. This  Agreement  (and the  Option  granted  hereby)  are  exchangeable,
without expense, at the option of the Holder, 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 Common Stock  purchasable  hereunder.
The terms "Agreement" and "Option" as

                                        7





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.  Any such new  Agreement  executed  and  delivered  shall
constitute an additional  contractual  obligation on the part of Issuer, whether
or not the Agreement so lost,  stolen,  destroyed or mutilated shall at any time
be enforceable by anyone.

      5. In addition to the  adjustment  in the number of shares of Common Stock
that are  purchasable  upon exercise of the Option pursuant to Section 1 of this
Agreement, the number of shares of Common Stock purchasable upon the exercise of
the Option and the Option Price shall be subject to adjustment from time to time
as provided in this Section 5.

      (a) In the event of any change in Issuer Common Stock by reason of a stock
dividend,  stock split,  split-up,  recapitalization,  combination,  exchange of
shares or  similar  transaction,  the type and  number  of shares or  securities
subject to the Option  shall be  adjusted  appropriately,  and proper  provision
shall be made in the agreements  governing such transaction so that Holder shall
receive,  upon  exercise of the Option,  the number and class of shares or other
securities  or  property  that Holder  would have  received in respect of Issuer
Common Stock if the Option had been exercised  immediately  prior to such event,
or the record date therefor,  as applicable.  If any additional shares of Issuer
Common Stock are issued after the date of this Agreement (other than pursuant to
an event  described  in the first  sentence of this  Section  5(a) or other than
pursuant to this Agreement), the number of shares of Issuer Common Stock subject
to the option shall be adjusted so that,  after such issuance,  it together with
any shares of Issuer Common Stock  previously  issued  pursuant  hereto,  equals
19.9%  of  the  number  of  shares  of  Issuer  Common  Stock  then  issued  and
outstanding,  without giving effect to any shares subject to or issued  pursuant
to the Option.

      (b)  Whenever  the  number  of shares of  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 Common  Stock  purchasable
prior to the adjustment and the

                                        8





denominator  of which  shall be equal to the  number of  shares of Common  Stock
purchasable after the adjustment.

      6. Upon the occurrence of a Subsequent  Triggering Event that occurs prior
to an  Exercise  Termination  Event,  Issuer  shall,  at the  request of Grantee
delivered  within six months (or such later period as provided in Section 10) of
such Subsequent  Triggering Event (whether on its own behalf or on behalf of any
subsequent  holder of this  Option  (or part  thereof)  or any of the  shares of
Common Stock issued pursuant hereto),  promptly prepare, file and keep current a
shelf  registration  statement under the Securities Act covering this Option and
any  shares  issued  and  issuable  pursuant  to this  Option  and shall use its
reasonable best efforts to cause such registration statement to become effective
and  remain  current in order to permit  the sale or other  disposition  of this
Option and any shares of Common Stock  issued upon total or partial  exercise of
this  Option  ("Option  Shares")  in  accordance  with any  plan of  disposition
requested by Grantee.  Issuer will use its reasonable best efforts to cause such
registration statement promptly to become effective and then to remain effective
for  such  period  not in  excess  of 6 months  from  the day such  registration
statement  first  becomes  effective or such  shorter time as may be  reasonably
necessary  to effect such sales or other  dispositions.  Grantee  shall have the
right to demand two such  registrations,  provided that any second  registration
shall be requested by Grantee within 12 months (or such later period as provided
in Section 10) following the occurrence of the Subsequent  Triggering Event. The
Issuer shall bear the costs of such  registrations  (including,  but not limited
to,  Issuer's  attorneys'  fees,  printing  costs and  filing  fees,  except for
underwriting   discounts  or  commissions,   brokers'  fees  and  the  fees  and
disbursements   of   Grantee's   counsel   related   thereto).   The   foregoing
notwithstanding,  if, at the time of any request by Grantee for  registration of
the Option or Option Shares as provided above,  Issuer is in  registration  with
respect to an underwritten  public offering by Issuer of shares of Common Stock,
and if in the good  faith  judgment  of the  managing  underwriter  or  managing
underwriters,  or,  if  none,  the sole  underwriter  or  underwriters,  of such
offering,  the offer and sale of the  Option  Shares  would  interfere  with the
successful marketing of the shares of Common Stock offered by Issuer, the number
of  Option  Shares  otherwise  to  be  covered  in  the  registration  statement
contemplated  hereby  may be  reduced;  provided,  however,  that after any such
required  reduction  the number of Option Shares to be included in such offering
for the account of all Holders shall constitute at least 25% of the total number
of shares to be sold by the Holders and Issuer in the  aggregate;  and  provided
further, however, that if

                                        9





such reduction occurs,  then Issuer shall file a registration  statement for the
balance as promptly as practicable  thereafter as to which no reduction pursuant
to this Section 6 shall be permitted or occur and the Holder shall thereafter be
entitled to one  additional  registration  and the 12-month  period  referred to
above  shall be  increased  to 18 months.  Each such  Holder  shall  provide all
information  reasonably  requested by Issuer for  inclusion in any  registration
statement to be filed  hereunder.  If requested by any such Holder in connection
with  such  registration,  Issuer  shall  become  a  party  to any  underwriting
agreement  relating  to the  sale of such  shares,  but  only to the  extent  of
obligating  itself in respect of  representations,  warranties,  indemnities and
other  agreements  customarily  included  in such  underwriting  agreements  for
Issuer. Upon receiving any request under this Section 6 from any Holder,  Issuer
agrees to send a copy thereof to any other person known to Issuer to be entitled
to  registration  rights under this Section 6, in each case by promptly  mailing
the same,  postage prepaid,  to the address of record of the persons entitled to
receive such copies.  Notwithstanding anything to the contrary contained herein,
in no event shall the number of registrations that Issuer is obligated to effect
be increased by reason of the fact that there shall be more than one Holder as a
result of any assignment or division of this Agreement.

      7. (a) At any time after the occurrence of a Repurchase  Event (as defined
below)  (i) at the  request  of  the  Holder,  delivered  prior  to an  Exercise
Termination  Event (or such later period as provided in Section 10),  Issuer (or
any successor  thereto)  shall  repurchase the Option from the Holder 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 this Option may then be exercised  and (ii) at
the  request  of the owner of  Option  Shares  from time to time (the  "Owner"),
delivered  prior to an  Exercise  Termination  Event  (or such  later  period as
provided in Section 10), Issuer (or any successor thereto) 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 Common  Stock at
which a tender or  exchange  offer  therefor  has been made,  (ii) the price per
share of Common Stock paid or to be paid by any third party,  other than Grantee
or a  Grantee  Subsidiary,  pursuant  to an  agreement  with  Issuer of the kind
described in Section 2(b)(i) hereof,  (iii) the highest closing price for shares
of Common Stock within the six-month period  immediately  preceding the date the
Holder gives notice of the required repurchase of this Option or the Owner gives
notice of the required  repurchase of Option Shares, as the case may be, or (iv)
in the event of a sale or  transfer of all or any  substantial  part of Issuer's
assets or  deposits,  the sum of the net price paid in such sale for such assets
or deposits and the current  market value of the  remaining net assets of Issuer
as determined by a nationally recognized investment banking firm selected by the
Holder or the Owner,  as the case may be, and  reasonably  acceptable to Issuer,
divided by the  number of shares of Common  Stock of Issuer  outstanding  at the
time of  such  sale.  In  determining  the  Market/Offer  Price,  the  value  of
consideration  other than cash shall be  determined  by a nationally  recognized
investment banking firm selected by the Holder or Owner, as the case may be, and
reasonably acceptable to Issuer.

      (b) The Holder and the Owner,  as the case may be, may  exercise its right
to require  Issuer to repurchase  the Option and 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 the Holder
or the Owner,  as the case may be, elects to require  Issuer to repurchase  this
Option  and/or the  Option  Shares in  accordance  with the  provisions  of this
Section 7. The Owner shall also  represent  and warrant  that it has sole record
and  beneficial  ownership of such Option Shares and that such Option Shares are
free and clear of all liens. As promptly as practicable, and in any event within
five  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 the Holder the Option
Repurchase  Price and/or to the Owner the Option Share Repurchase Price therefor
or the portion thereof that Issuer is not then prohibited  under  applicable law
and regulation from so delivering.

      (c) To the  extent  that  Issuer is  prohibited  under  applicable  law or
regulation,  or as a consequence of administrative policy, from repurchasing the
Option and/or the Option Shares in full,  Issuer shall immediately so notify the
Holder and/or the Owner and  thereafter  deliver or cause to be delivered,  from
time to time, to the Holder 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

                                       10





after  delivery  of a notice of  repurchase  pursuant to  paragraph  (b) of this
Section 7 is prohibited under applicable law or regulation,  or as a consequence
of administrative policy, or as a result of a written agreement or other binding
obligation with a governmental or regulatory body or agency,  from delivering to
the Holder and/or the Owner, as appropriate, the Option Repurchase Price and the
Option  Share  Repurchase  Price,  respectively,  in part or in full (and Issuer
hereby  undertakes  to use its  reasonable  best  efforts to obtain all required
regulatory and legal  approvals and to file any required  notices as promptly as
practicable  in order to accomplish  such  repurchase),  the Holder or Owner may
revoke its notice of repurchase of the Option and/or the Option Shares either in
whole or to the extent of the prohibition, whereupon, in the latter case, Issuer
shall promptly (i) deliver to the Holder and/or the Owner, as appropriate,  that
portion of the Option  Repurchase Price and/or the Option Share Repurchase Price
that Issuer is not prohibited  from delivering with respect to Options or Option
Shares as to which the Holder or the Owner,  as the case may be, has not revoked
its  repurchase  demand;  and (ii) deliver,  as  appropriate,  either (A) to the
Holder,  a new Stock  Option  Agreement  evidencing  the right of the  Holder to
purchase  that  number of shares of Common  Stock  obtained by  multiplying  the
number  of  shares of Common  Stock  for  which  the  surrendered  Stock  Option
Agreement was exercisable at the time of delivery of the notice of repurchase by
a  fraction,  the  numerator  of which is the Option  Repurchase  Price less the
portion thereof theretofore delivered to the Holder and the denominator of which
is the Option Repurchase  Price,  and/or (B) to the Owner, a certificate for the
Option  Shares  it is then  so  prohibited  from  repurchasing.  If an  Exercise
Termination  Event shall have occurred prior to the date of the notice by Issuer
described in the first sentence of this subsection (c), or shall be scheduled to
occur at any time before the  expiration of a period ending on the thirtieth day
after such date,  the Holder  shall  nonetheless  have the right to exercise the
Option until the expiration of such 30-day period.

      (d) For purposes of this Section 7, a  "Repurchase  Event" shall be deemed
to  have  occurred  upon  the  occurrence  of  any of the  following  events  or
transactions after the date hereof:

                  (i) the  acquisition  by any person (other than Grantee or any
      Grantee  Subsidiary)  of  beneficial  ownership of 50% or more of the then
      outstanding Common Stock; or

                  (ii) the consummation of any Acquisition Transaction described
      in Section  2(b)(i)  hereof,  except  that the  percentage  referred to in
      clause (z) shall be 50%.

                                       11





      8. (a) In the event that prior to an Exercise  Termination  Event,  Issuer
shall enter into an agreement (i) to consolidate  with or merge into any person,
other than Grantee or a Grantee Subsidiary, or engage in a plan of exchange 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 or the
acquirer in such plan of exchange, (ii) to permit any person, other than Grantee
or a Grantee Subsidiary, to merge into Issuer or be acquired by Issuer in a plan
of  exchange  and Issuer  shall be the  continuing  or  surviving  or  acquiring
corporation,  but, in connection with such merger or plan of exchange,  the then
outstanding  shares of 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 Common  Stock  shall  after such  merger or plan of
exchange represent less than 50% of the outstanding shares and share equivalents
of the merged or acquiring  company,  or (iii) to sell or otherwise transfer all
or a substantial part of its or the Issuer savings bank  Subsidiary's  assets or
deposits to any person, other than Grantee or a Grantee Subsidiary, then, and in
each such case,  the  agreement  governing  such  transaction  shall make proper
provision  so  that  the  Option  shall,  upon  the  consummation  of  any  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
the Holder, of either (x) the Acquiring  Corporation (as hereinafter defined) or
(y) any person that controls the Acquiring Corporation.

      (b)         The following terms have the meanings indicated:

                  (i) "Acquiring  Corporation"  shall mean (i) the continuing or
      surviving  person of a consolidation  or merger with Issuer (if other than
      Issuer),  (ii) the acquiring  person in a plan of exchange in which Issuer
      is  acquired,  (iii) the Issuer in a merger or plan of  exchange  in which
      Issuer is the  continuing or surviving or acquiring  person,  and (iv) the
      transferee of all or a substantial part of Issuer's assets or deposits (or
      the assets or deposits of the Issuer savings bank Subsidiary).

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

                  (iii) "Assigned Value" shall mean the  Market/Offer  Price, as
      defined in Section 7.

                                       12





                  (iv) "Average Price" shall mean the average closing price of a
      share of the Substitute  Common Stock for one year  immediately  preceding
      the consolidation,  merger, share exchange 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,  share echange 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 common stock
      issued by the person  merging into Issuer or by any company which controls
      or is controlled by such person, as the Holder may elect.

      (c) The  Substitute  Option  shall  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 the Holder. The issuer of the Substitute Option shall
also enter into an agreement  with the then Holder or Holders of the  Substitute
Option in substantially the same form as this Agreement (after giving effect for
such  purpose  to the  provisions  of  Section  9),  which  agreement  shall  be
applicable to the Substitute Option.

      (d) The Substitute  Option shall be exercisable  for such number of shares
of Substitute  Common Stock as is equal to the Assigned Value  multiplied by the
number  of  shares  of  Common  Stock  for  which  the  Option  was  exercisable
immediately  prior to the event described in the first sentence of Section 8(a),
divided by the Average Price.  The exercise  price of the Substitute  Option per
share of  Substitute  Common  Stock  shall  then be equal  to the  Option  Price
multiplied  by a fraction,  the numerator of which shall be the number of shares
of Common Stock for which the Option was  exercisable  immediately  prior to the
event  described in the first  sentence of Section 8(a) and the  denominator  of
which  shall be the number of shares of  Substitute  Common  Stock for which the
Substitute Option is exercisable.

      (e) In no event,  pursuant to any of the foregoing  paragraphs,  shall the
Substitute Option be exercisable for more than 19.9% of the shares of Substitute
Common Stock  outstanding  prior to exercise of the  Substitute  Option.  In the
event that the Substitute Option would be exercisable for more than 19.9% of the
shares of  Substitute  Common Stock  outstanding  prior to exercise but for this
clause (e), the issuer of the Substitute Option (the "Substitute Option Issuer")
shall make a cash  payment to Holder 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

                                       13





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 a majority in interest of the Holders and
the Owners and reasonably acceptable to the Acquiring Corporation.

      (f) Issuer shall not enter into any  transaction  described in  subsection
(a) of this  Section 8 unless the  Acquiring  Corporation  and any  person  that
controls the  Acquiring  Corporation  assume in writing all the  obligations  of
Issuer hereunder.

      9.  (a) At the  request  of the  holder  of  the  Substitute  Option  (the
"Substitute  Option Holder"),  the Substitute Option Issuer shall repurchase the
Substitute  Option from the Substitute Option Holder at a price (the "Substitute
Option  Repurchase  Price") equal to the amount by which (i) the Highest Closing
Price (as hereinafter defined) exceeds (ii) the exercise price of the Substitute
Option,  multiplied by the number of shares of Substitute Common Stock for which
the  Substitute  Option may then be  exercised,  and at the request of the owner
(the  "Substitute  Share  Owner")  of shares of  Substitute  Common  Stock  (the
"Substitute  Shares"),   the  Substitute  Option  Issuer  shall  repurchase  the
Substitute Shares at a price (the "Substitute Share Repurchase  Price") equal to
the Highest  Closing  Price  multiplied  by the number of  Substitute  Shares so
designated.  The term  "Highest  Closing  Price" shall mean the highest  closing
price for  shares  of  Substitute  Common  Stock  within  the  six-month  period
immediately  preceding the date the Substitute Option Holder gives notice of the
required repurchase of the Substitute Option or the Substitute Share Owner gives
notice of the required repurchase of the Substitute Shares, as applicable.

      (b) Each Substitute  Option Holder and Substitute Share Owner, as the case
may be, may  exercise its  respective  rights to require the  Substitute  Option
Issuer to repurchase the Substitute Option and the Substitute Shares pursuant to
this Section 9 by surrendering for such purpose to the Substitute Option Issuer,
at its principal  office,  the agreement for such Substitute  Option (or, in the
absence of such an agreement,  a copy of this Agreement) and/or certificates for
Substitute  Shares  accompanied by a written notice or notices  stating that the
Substitute  Option  Holder or the  Substitute  Share Owner,  as the case may be,
elects to require the  Substitute  Option  Issuer to repurchase  the  Substitute
Option and/or the  Substitute  Shares in accordance  with the provisions of this
Section 9. As promptly as practicable and in any event within five business days
after the surrender of the Substitute  Option and/or  certificates  representing
Substitute Shares and the receipt of such

                                       14





notice or notices relating  thereto,  the Substitute Option Issuer shall deliver
or cause to be delivered to the Substitute  Option Holder the Substitute  Option
Repurchase  Price  and/or to the  Substitute  Share Owner the  Substitute  Share
Repurchase  Price  therefor or, in either case,  the portion  thereof  which the
Substitute  Option  Issuer  is not  then  prohibited  under  applicable  law and
regulation from so delivering.

      (c) To the extent that the  Substitute  Option Issuer is prohibited  under
applicable law or regulation,  or as a consequence of administrative  policy, or
as  a  result  of a  written  agreement  or  other  binding  obligation  with  a
governmental  or regulatory  body or agency,  from  repurchasing  the Substitute
Option and/or the Substitute  Shares in part or in full,  the Substitute  Option
Issuer shall  immediately  so notify the  Substitute  Option  Holder  and/or the
Substitute  Share Owner and  thereafter  deliver or cause to be delivered,  from
time to time, to the Substitute Option Holder and/or the Substitute Share Owner,
as appropriate, the portion of the Substitute Option Repurchase Price and/or the
Substitute  Share  Repurchase  Price,  respectively,   which  it  is  no  longer
prohibited  from  delivering,  within five business days after the date on which
the Substitute Option Issuer is no longer so prohibited; provided, however, that
if the  Substitute  Option  Issuer is at any time after  delivery of a notice of
repurchase  pursuant  to  subsection  (b) of this  Section  9  prohibited  under
applicable law or regulation,  or as a consequence of administrative  policy, or
as  a  result  of a  written  agreement  or  other  binding  obligation  with  a
governmental  or regulatory  body or agency,  from  delivering to the Substitute
Option Holder and/or the Substitute Share Owner, as appropriate,  the Substitute
Option Repurchase Price and the Substitute Share Repurchase Price, respectively,
in full (and the Substitute  Option Issuer shall use its reasonable best efforts
to  receive  all  required   regulatory  and  legal  approvals  as  promptly  as
practicable  in order to accomplish  such  repurchase),  the  Substitute  Option
Holder and/or  Substitute Share Owner may revoke its notice of repurchase of the
Substitute  Option or the Substitute  Shares either in whole or to the extent of
prohibition,  whereupon,  in the latter case, the Substitute Option Issuer shall
promptly (i) deliver to the Substitute  Option Holder or Substitute Share Owner,
as appropriate,  that portion of the Substitute  Option  Repurchase Price or the
Substitute  Share  Repurchase  Price that the  Substitute  Option  Issuer is not
prohibited from delivering; and (ii) deliver, as appropriate,  either (A) to the
Substitute  Option Holder, a new Substitute  Option  evidencing the right of the
Substitute  Option  Holder to purchase  that number of shares of the  Substitute
Common Stock obtained by multiplying the number of shares of the

                                       15





Substitute  Common  Stock  for  which  the  surrendered  Substitute  Option  was
exercisable  at the time of delivery of the notice of  repurchase by a fraction,
the  numerator  of which is the  Substitute  Option  Repurchase  Price  less the
portion thereof  theretofore  delivered to the Substitute  Option Holder and the
denominator of which is the Substitute Option  Repurchase  Price,  and/or (B) to
the Substitute Share Owner, a certificate for the Substitute Option Shares it is
then so prohibited from  repurchasing.  If an Exercise  Termination  Event shall
have occurred  prior to the date of the notice by the  Substitute  Option Issuer
described in the first sentence of this subsection (c), or shall be scheduled to
occur at any time before the  expiration of a period ending on the thirtieth day
after such date, the Substitute Option Holder shall  nevertheless have the right
to exercise the Substitute Option until the expiration of such 30-day period.

      10. The 30-day,  6-month,  12-month or  18-month  periods for  exercise of
certain rights under Sections 2, 6, 7 and 9 shall be extended: (i) to the extent
necessary to obtain all  regulatory  approvals  for the exercise of such rights,
and for the  expiration  of all  statutory  waiting  periods;  (ii)  during  the
pendency of any temporary  restraining  order,  injunction or other legal bar to
the  exercise  of such  rights;  and  (iii)  to the  extent  necessary  to avoid
liability under Section 16(b) of the Exchange Act by reason of such exercise.

      11. Issuer hereby represents and warrants to Grantee as follows:

      (a) Issuer has full  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 and validly  authorized by the
Issuer Board on or prior to the date hereof 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 and validly
executed and delivered by Issuer.

      (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
Common  Stock equal to the maximum  number of shares of Common Stock at any time
and from time to time issuable hereunder, and all such shares, upon

                                       16





issuance pursuant thereto, will be duly authorized,  validly issued, fully paid,
nonassessable,  and will be  delivered  free and  clear  of all  claims,  liens,
encumbrance and security interests and not subject to any preemptive rights.

      12. Grantee hereby represents and warrants to Issuer that:

      (a) Grantee has all requisite corporate power and authority to enter into,
execute and deliver this  Agreement  and,  subject to any  approvals or consents
referred to herein,  to consummate the  transactions  contemplated  hereby.  The
execution  and  delivery  of  this  Agreement  and  the   consummation   of  the
transactions  contemplated  hereby have been duly  authorized  by all  necessary
corporate  action on the part of Grantee and no other  corporate  proceedings on
the part of Grantee are necessary to authorize  this  Agreement or to consummate
the  transactions  so  contemplated.  This  Agreement has been duly executed and
delivered by Grantee.

      (b) The  Option is not  being,  and any  shares  of Common  Stock or other
securities acquired by Grantee upon exercise of the Option will not be, acquired
with a view to the public  distribution  thereof and will not be  transferred or
otherwise  disposed  of  except  in a  transaction  registered  or  exempt  from
registration under the Securities Act.

      13.  Neither  of the  parties  hereto  may  assign  any of its  rights  or
obligations  under this Agreement or the Option  created  hereunder to any other
person,  without the express written consent of the other party,  except that in
the event a Subsequent Triggering Event shall have occurred prior to an Exercise
Termination Event, Grantee, subject to the express provisions hereof, may assign
in whole or in part its  rights  and  obligations  hereunder  within  six months
following such Subsequent  Triggering Event;  provided,  however, that until the
date 15 days following the date on which the applicable bank or thrift regulator
has  approved an  application  by Grantee to acquire the shares of Common  Stock
subject to the Option,  but only if such  approval is required,  Grantee may not
assign  its  rights  under the Option  except in (i) a widely  dispersed  public
distribution,  (ii) a private placement in which no one party acquires the right
to purchase in excess of 2% of the voting shares of Issuer,  (iii) an assignment
to a single party (e.g., a broker or investment  banker) for the sole purpose of
conducting a widely  dispersed  public  distribution on Grantee's behalf or (iv)
any other manner approved by the applicable bank or thrift regulator.


                                       17





      14.  Each of Grantee and Issuer will use its  reasonable  best  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.

      15. (a) Grantee may, at any time following a Repurchase Event and prior to
the  occurrence  of an  Exercise  Termination  Event  (or such  later  period as
provided in Section 10),  relinquish the Option (together with any Option Shares
issued to and then owned by Grantee) to Issuer in exchange  for a cash fee equal
to the Surrender Price (as hereinafter defined); provided, however, that Grantee
may  not  exercise  its  rights  pursuant  to  this  Section  15 if  Issuer  has
repurchased the Option (or any portion thereof) or any Option Shares pursuant to
Section 7. The  "Surrender  Price" shall be equal to $4.4  million (i) plus,  if
applicable,  Grantee's purchase price with respect to any Option Shares and (ii)
minus, if applicable,  the excess of (A) the net cash amounts,  if any, received
by Grantee or a Grantee  Subsidiary  pursuant to the arms' length sale of Option
Shares (or any other  securities into which such Option Shares were converted or
exchanged) to any unaffiliated  party, over (B) Grantee's purchase price of such
Option Shares.

      (b) Grantee may exercise its right to relinquish the Option and any Option
Shares pursuant to this Section 15 by  surrendering to Issuer,  at its principal
office, a copy of this Agreement  together with  certificates for Option Shares,
if any,  accompanied  by a written  notice  stating (i) that  Grantee  elects to
relinquish  the  Option  and  Option  Shares,  if any,  in  accordance  with the
provisions of this Section 15 and (ii) the Surrender  Price. The Surrender Price
shall be payable in immediately available funds on or before the second business
day following receipt of such notice by Issuer.

      (c) To the  extent  that  Issuer is  prohibited  under  applicable  law or
regulation,  or as a consequence of  administrative  policy, or as a result of a
written agreement or other binding  obligation with a governmental or regulatory
body or agency, from paying the Surrender Price to Grantee in full, Issuer shall
immediately so notify  Grantee and thereafter  deliver or cause to be delivered,
from time to time, to Grantee,  the portion of the Surrender Price that it is no
longer prohibited from paying, 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  surrender  pursuant  to  paragraph  (b) of this
Section 15 is prohibited under applicable law or regulation, or as a consequence
of administrative policy, or as a result of a written agreement or

                                       18





other binding obligation with a governmental or regulatory body or agency,  from
paying to Grantee  the  Surrender  Price in full,  (i) Issuer  shall (A) use its
reasonable  best efforts to obtain all required  regulatory and legal  approvals
and to file any  required  notices as promptly as  practicable  in order to make
such  payments,  (B)  within  five  days of the  submission  or  receipt  of any
documents  relating to any such regulatory and legal approvals,  provide Grantee
with copies of the same, and (c) keep Grantee  advised of both the status of any
such request for regulatory and legal approvals, as well as any discussions with
any relevant  regulatory or other third party reasonably related to the same and
(ii)  Grantee  may revoke such  notice of  surrender  by delivery of a notice of
revocation  to Issuer  and,  upon  delivery of such  notice of  revocation,  the
Exercise  Termination Event shall be extended to a date six months from the date
on which the  Exercise  Termination  Event  would have  occurred  if not for the
provisions of this Section  15(c) (during which period  Grantee may exercise any
of its rights  hereunder,  including any and all rights pursuant to this Section
15).

      16. 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.  In connection  therewith  both
parties waive the posting of any bond or similar requirement.

      17. 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 the Holder is not  permitted  to acquire,  or Issuer or  Substitute  Option
Issuer, as the case may be, is not permitted to repurchase  pursuant to Sections
7 or 9, as the case may be, the full number of shares of Common  Stock  provided
in  Section  l(a)  hereof (as  adjusted  pursuant  to Section  l(b) or Section 5
hereof),  it is the  express  intention  of Issuer  (which  shall be  binding on
Substitute Option Issuer) to allow the Holder to acquire or to require Issuer or
Substitute  Option Issuer,  as the case may be, to repurchase such lesser number
of shares as may be permissible, without any amendment or modification hereof.


                                       19





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