EXHIBIT 99.3

                  STOCK OPTION AGREEMENT DATED APRIL 24, 1998


                             STOCK OPTION AGREEMENT

     STOCK OPTION AGREEMENT,  dated as of April 24, 1998, between Ambanc Holding
Co.,  Inc., a Delaware  corporation  ("Grantee"),  and AFSALA  Bancorp,  Inc., a
Delaware corporation ("Issuer").

                              W I T N E S S E T H:

     WHEREAS,  Grantee and Issuer have entered into a Reorganization  and Merger
Agreement (the "Merger Agreement");

     WHEREAS,  as an  inducement  to the  willingness  of Grantee to continue to
pursue the transactions contemplated by 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 prior to the date hereof;

     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
344,500 fully paid and nonassessable  shares of the common stock, par value $.10
per share,  of Issuer  ("Common  Stock") at a price per share  equal to the last
reported  sale price per share of Common  Stock as reported on the Nasdaq  Stock
Market on April 22, 1998; provided,  however, that in the event Issuer issues or
agrees to issue any shares of Common  Stock  (other than shares of Common  Stock
issued  pursuant to stock  options  granted prior to the date hereof) at a price
less than  such  price per share (as  adjusted  pursuant  to  subsection  (b) of
Section  5), such price shall be equal to such  lesser  price  (such  price,  as
adjusted if applicable, the "Option Price"); provided, further, 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.  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 other than  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 in breach of any provision of the Merger Agreement.

     2. (a) The Holder (as  hereinafter  defined) may  exercise  the Option,  in
whole or part, if, but only if, 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 (6) months following such Subsequent  Triggering Event (or such later period
as  provided  in  Section  10).  Each  of the  following  shall  be an  Exercise
Termination Event: (i) the Effective Time of the Merger; (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  5.4(c)  due to a breach  of the
Company's  covenants at Sections  4.2,  4.3, 4.4, 4.6 or 4.9 or the condition at
Section 5.2(e) of the Merger Agreement (but only if the breach giving






rise to the termination was willful)  (each, a "Listed  Termination");  or (iii)
the  passage of  eighteen  (18)  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  is  a  Listed
Termination.  The term "Holder"  shall mean the holder or holders of the Option.
Notwithstanding  anything to the contrary  contained herein,  (i) the Option may
not be exercised at any time when Grantee shall be in material  breach of any of
its covenants or agreements  contained in the Merger  Agreement such that Issuer
shall be entitled to  terminate  the Merger  Agreement as a result of a material
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  Significant  Subsidiary (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
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 "1934 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 other than
as contemplated  by the Merger  Agreement.  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  involving solely Issuer and/or
one or more  wholly-owned  (except  for  directors'  qualifying  shares and a de
minimis number of other shares) Subsidiaries of the Issuer,  provided,  any such
transaction  is not  entered  into  in  violation  of the  terms  of the  Merger
Agreement), (y) a purchase, lease or other acquisition 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)  "Subsidiary"  shall have the
meaning set forth in Rule 12b-2 under the 1934 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 1934 Act, and the rules and regulations thereunder);

          (iii) The  shareholders of Issuer shall have voted and failed to adopt
the Merger  Agreement  at a meeting  which has been held for that purpose or any
adjournment or postponement thereof, or such meeting shall not have been held in
violation  of the  Merger  Agreement  or  shall  have  been  canceled  prior  to
termination  of the  Merger  Agreement  if,  prior to such  meeting  (or if such
meeting  shall  not have been held or shall  have been  canceled,  prior to such
termination),  it shall have been publicly announced that any person (other than
Grantee or any of its  Subsidiaries)  shall have made, or publicly  disclosed an
intention to make, a proposal to engage in an Acquisition Transaction;

          (iv) The Issuer  Board shall have  withdrawn  or 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,  or Issuer or any Issuer
Subsidiary 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;

          (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 in anticipation of engaging in an Acquisition
Transaction,  and following  such breach  Grantee would be entitled to terminate
the  Merger  Agreement  (whether  immediately  or after the  giving of notice or
passage of time or both); or

          (vii) Any person  other than Grantee or any Grantee  Subsidiary  shall
have filed an application or notice with the Office of Thrift  Supervision  (the
"OTS") or other federal or state 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

          (ii) The  occurrence  of the 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 the OTS or any other
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.

     (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.

     (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  should be
exercised in part only, a new Option evidencing the rights of the Holder thereof
to purchase the balance of the shares purchasable hereunder.







     (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,  dated as of April 23, 1998, 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 "1933 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 1933 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;
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 and
the tender of the applicable purchase price in immediately  available funds, 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 amendment of its  certificate of  incorporation  or through
reorganization,  consolidation, merger, dissolution or sale of assets, or by any
other voluntary act, avoid or seek to avoid the observance or performance of any
of the  covenants,  stipulations  or  conditions  to be  observed  or  performed
hereunder by Issuer;  (iii) promptly to take all action as may from time to time
be required (including (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 the Savings and
Loan Holding  Company Act ("SLHCA"),  or the Change in Bank Control Act of 1978,
as amended,  or any state or other  federal  banking law,  prior  approval of or
notice  to the OTS or to any  state or other  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 the
OTS or such state or other 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 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, or  distributions  in  respect  of, the
Common   Stock   by   reason   of   stock   dividends,    split-ups,    mergers,
recapitalizations,  combinations, subdivisions, conversions, exchanges of shares
or the like,  the type and  number of shares of 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 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 Common
Stock that remain  subject to the Option shall be increased so that,  after such
issuance and together with shares of Common Stock previously  issued pursuant to
the  exercise  of the Option  (as  adjusted  on account of any of the  foregoing
changes in the Common Stock),  it equals 19.9% of the number of shares of Common
Stock then issued and outstanding.

     (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  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 twelve (12) 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  registration  statement  under the 1933 Act  covering  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 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
180 days 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. 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
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 the Holder  shall  constitute  at least 25% of the
total number of shares to be sold by the Holder and Issuer in the aggregate; and
provided further, however, that if 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 twelve (12) month period  referred to in the first  sentence of this section
shall be increased to  twenty-four  (24) 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 to be paid by any third party  pursuant  to an  agreement
with Issuer,  (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
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. 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  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, from delivering to the
Holder and/or the Owner, as  appropriate,  the Option  Repurchase  Price and the
Option  Share  Repurchase  Price,  respectively,  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  whether 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; and (ii) deliver, as appropriate,
either (A) to the Holder, a new 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  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%.

     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  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
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.

          (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  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 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 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 the Holder.







     (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  issuer  of  the  Substitute  Option  (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) The  Substitute  Option Holder and the 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 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 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, 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 (5) 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,  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 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,  18-month  or  24-month  periods  for
exercise  of  certain  rights  under  Sections  2, 6, 7, 9, 12 and 14  shall  be
extended: (i) to the extent necessary to obtain all regulatory approvals for the
exercise of such rights (for so long as the  Holder,  Owner,  Substitute  Option
Holder or  Substitute  Share  Owner,  as the case may be, is using  commercially
reasonable efforts to obtain such regulatory approvals),  and for the expiration
of all  statutory  waiting  periods;  and (ii) to the extent  necessary to avoid
liability under Section 16(b) of the 1934 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 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 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.  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;  provided,  however,
that until the date 15 days  following the date on which the OTS has approved an
application  by  Grantee to acquire  the shares of Common  Stock  subject to the
Option,  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 purpose of conducting a widely dispersed public  distribution on
Grantee's behalf or (iv) any other manner approved by the OTS.

     13. 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,  including,  without  limitation,  applying to the OTS under the
SLHCA for approval to acquire the shares issuable  hereunder,  but Grantee shall
not be






obligated to apply to applicable banking authorities for approval to acquire the
shares of Common Stock issuable  hereunder until such time, if ever, as it deems
appropriate to do so.

     14. (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;  provided,  however,  that Grantee may not exercise its
rights  pursuant to this Section 14 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 $1.4  million  (i)  plus,  if  applicable,  Grantee's
purchase price with respect to any Option Shares and (ii) minus,  if applicable,
the excess of (B) the net cash amounts,  if any, received by Grantee 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 14 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 14 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,  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 14 is prohibited
under  applicable  law or  regulation,  or as a  consequence  of  administrative
policy, 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  Date shall be extended to a date six months from the date
on which the  Exercise  Termination  Date  would  have  occurred  if not for the
provisions of this Section  14(c) (during which period  Grantee may exercise any
of its rights  hereunder,  including any and all rights pursuant to this Section
14).

     15. 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.

     16. 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 is not  permitted  to
repurchase  pursuant  to  Section 7, 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 to allow the Holder to acquire or to require Issuer to repurchase such
lesser  number  of  shares  as may be  permissible,  without  any  amendment  or
modification hereof.

     17.  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.

     18. This  Agreement  shall be governed by and construed in accordance  with
the  laws of the  State of New  York,  without  regard  to the  conflict  of law
principles  thereof  (except to the extent that mandatory  provisions of Federal
law are applicable).

     19. This  Agreement  may be executed in two or more  counterparts,  each of
which shall be deemed to be an original,  but all of which shall  constitute one
and the same agreement.

     20.  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,  including fees and
expenses of its own financial consultants,  investment bankers,  accountants and
counsel.

     21.  Except  as  otherwise  expressly  provided  herein  or in  the  Merger
Agreement, 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 assignees.
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
assignees, any rights,  remedies,  obligations or liabilities under or by reason
of this Agreement, except as expressly provided herein.

     22.  Capitalized  terms used in this Agreement and not defined herein shall
have the meanings assigned thereto in the Merger Agreement.







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