To the Shareholders of IBS Financial Corp.:


         We cordially invite you to attend a special meeting of the shareholders
of IBS  Financial  Corp.  ("IBSF").  The  meeting is to be held at the Hilton At

August 10, 1998, at 11:00 am.

    

         We have called the meeting to seek your approval of a Merger  Agreement

converted  into 0.534 shares of HUBCO Common  Stock,  subject to  adjustment  in
certain  circumstances.  Cash  will be paid in lieu of  fractional  shares.  The
investment  banking  firm of Ryan,  Beck & Co.,  Inc.  has advised your Board of
Directors  that, in its opinion dated July 10, 1998,  the exchange ratio is fair
to the holders of IBSF Common Stock from a financial point of view.

receipt of bank regulatory approvals and approval of the Merger Agreement by the
affirmative  vote of a majority of the votes cast by the holders of  outstanding
shares of IBSF Common Stock entitled to vote at the Meeting.

         We urge you to read the attached Proxy Statement-Prospectus  carefully.
It  describes  the Merger  Agreement in detail and includes a copy of the Merger
Agreement as Appendix A.

         Your Board of Directors has unanimously  approved the Merger  Agreement
and unanimously recommends that you vote "FOR" approval of the Merger Agreement.

         It is very  important  that your shares be  represented  at the special

         All  shareholders  are urged to attend the  Meeting  in  person.  It is
important  that  proxies  be  returned  promptly.  Whether or not you plan to be
present in person at the Meeting,  please  date,  sign and complete the enclosed
proxy and  return it in the  enclosed  envelope,  which  requires  no postage if
mailed in the United States. If you decide to attend the Meeting, you may revoke
your proxy and vote your shares in person. If you are a shareholder whose shares
are not registered in your name, you will need additional documentation from the
holder of record of your shares to vote personally at the Meeting.

                                        By Order of the Board of Directors

PROXY STATEMENT OF                          PROSPECTUS OF HUBCO, INC.
IBS FINANCIAL CORP.                         for its Common Stock to be issued
for its Special Meeting of Shareholders     in connection with the merger of
to be held on August 10, 1998               IBS Financial Corp.
and all adjournments or postponements       with and into HUBCO, Inc.
thereof

         The Board of Directors  of IBS  Financial  Corp.  ("IBSF") has called a
Special  Meeting  of IBSF  shareholders  (the  "Meeting")  to be held on Monday,
August 10, 1998. The Meeting has been called to seek IBSF  shareholder  approval
of a Merger  Agreement  which  provides  for IBSF to be merged with HUBCO,  Inc.
("HUBCO"),  with HUBCO as the  surviving  corporation.  HUBCO is a bank  holding
company with bank  subsidiaries  based in New Jersey,  New York and Connecticut.
Immediately  following  completion  of  the  Merger  of  IBSF  into  HUBCO  (the
"Merger"), IBSF's subsidiary,  Inter-Boro Savings and Loan Association,  will be
merged into HUBCO's New Jersey banking subsidiary, Hudson United Bank.

    

         Upon completion of the Merger,  each share of IBSF Common Stock (except
for treasury shares and certain shares held by HUBCO or its  subsidiaries)  will
be converted into 0.534 shares (the "Exchange Ratio") of HUBCO Common Stock. The
Exchange Ratio is subject to adjustment in certain circumstances,  as more fully
described  in the  accompanying  Proxy  Statement-Prospectus  and in the  Merger
Agreement which is an Appendix thereto. HUBCO will pay cash to IBSF stockholders
in lieu of issuing fractional shares of HUBCO Common Stock.

         Completion  of the Merger is subject to certain  conditions,  including
bank  regulatory   approvals  and  approval  of  the  Merger  Agreement  by  the
affirmative  vote of a majority of the votes cast by the holders of  outstanding
shares of IBSF Common Stock entitled to vote at the Meeting.

         HUBCO  has  filed a  Registration  Statement  with the  Securities  and
Exchange  Commission  (the "SEC")  covering the HUBCO Common Stock which will be
issued in connection with the Merger. This Proxy Statement-Prospectus serves two
purposes. It is the Proxy Statement being used by the IBSF Board of Directors to
solicit proxies for the Meeting, and it is the Prospectus of HUBCO regarding the
HUBCO Common Stock to be issued if the Merger is  completed.  This document does
not serve as a  prospectus  to cover any  resales  of HUBCO  Common  Stock to be
issued in connection with the Merger. Persons who are considered "affiliates" of
IBSF under  applicable  securities laws will be subject to restrictions on their
ability to resell the HUBCO Common Stock received by them in the Merger.

   

         This document is first being sent to IBSF shareholders on or about July
10, 1998. It describes the Merger Agreement in detail and includes a copy of the
Merger  Agreement  as  Appendix  A.  IBSF  shareholders  are  urged to read this
document carefully.

                      SUMMARY OF PROXY STATEMENT-PROSPECTUS

         The following is a summary of certain information regarding the matters
to be considered at the Meeting.  This summary is necessarily  incomplete and is
qualified by the more  detailed  information  contained  elsewhere in this Proxy
Statement,  the  appendixes  hereto  and the  documents  incorporated  herein by
reference. IBSF shareholders should carefully read all such materials.

Overview

   

         The Board of Directors  of IBS  Financial  Corp.  ("IBSF") has called a
Special  Meeting  of IBSF  shareholders  (the  "Meeting")  to be held on Monday,
August 10, 1998. The Meeting has been called to seek shareholder  approval of an
Agreement and Plan of Merger dated as of March 31, 1998 (the "Merger Agreement")
among  HUBCO,  Inc.  ("HUBCO"),  Hudson  United  Bank  ("HUB"),  IBSF and IBSF's
principal   subsidiary,   Inter-Boro   Savings   and   Loan   Association   (the
"Association").  The Merger Agreement  provides for IBSF to be merged with HUBCO
(the "Merger"),  with HUBCO as the surviving  corporation.  A copy of the Merger
Agreement is attached as Appendix A to this Proxy Statement.

    

         Upon  completion of the Merger,  each share of common stock,  par value
$.01 per share,  of IBSF ("IBSF Common  Stock"),  other than Excluded Shares (as
defined  below),  will be converted into 0.534 shares (the "Exchange  Ratio") of
common stock of HUBCO, no par value ("HUBCO Common  Stock").  The Exchange Ratio
is subject to adjustment in certain  circumstances,  as more fully  described in
the Proxy  Statement and in the Merger  Agreement  which is an Appendix  hereto.
HUBCO will pay cash to IBSF stockholders in lieu of issuing fractional shares of
HUBCO  Common  Stock.  "Excluded  Shares" are those  shares of IBSF Common Stock
which are (i) held by IBSF as treasury  shares,  or (ii) held by HUBCO or any of
its subsidiaries  (other than shares held as trustee or in a fiduciary  capacity
and shares held as collateral on or in lieu of a debt previously contracted).

         At the  Meeting,  holders of IBSF Common Stock will be asked to approve
and adopt the Merger  Agreement and, in the discretion of the Board of Directors
of IBSF,  to approve a proposal  (the  "Adjournment  Proposal")  to adjourn  the
Meeting in order to solicit  additional  proxies if there are insufficient votes
at the time of the Meeting to approve the Merger Agreement.

         This document serves two purposes. It is the Proxy Statement being used
by the IBSF Board of Directors to solicit proxies for the Meeting, and it is the
Prospectus of HUBCO  regarding the HUBCO Common Stock to be issued if the Merger
is completed.  Therefore,  this document is sometimes  referred to as either the
"Proxy Statement-Prospectus" or the "Proxy Statement."

The Meeting

   

         The Meeting will be held on Monday, August 10, 1998 at 11:00 am, at the
Hilton At Cherry Hill, 2349 West Marlton Pike, Cherry Hill, New Jersey 08002. At
the Meeting, holders of IBSF Common Stock will be asked to approve and adopt the
Merger  Agreement and in the discretion of the Board of Directors to approve the
Adjournment Proposal.

         Record  holders of IBSF  Common  Stock at the close of business on June
12, 1998 (the "Record  Date") are entitled to vote at the Meeting.  Holders of a
majority of the outstanding  shares of IBSF Common Stock entitled to vote at the
Meeting must be present or represented by proxy at the Meeting for a quorum. The
affirmative  vote, in person or by proxy, of a majority of the votes cast by the
holders of  outstanding  shares of IBSF  Common  Stock  entitled  to vote at the
Meeting is  required  in order to approve  and adopt the Merger  Agreement.  The
affirmative vote of the holders of a majority of the votes cast affirmatively or
negatively is required in order to approve and adopt the  Adjournment  Proposal.
As of the Record Date, there were 10,962,116  outstanding  shares of IBSF Common
Stock held by approximately  1,930 holders of record.  The directors of IBSF and
the  Association  as a group have voting  control  over  739,373 of these shares
(6.7%)  (excluding  unallocated  shares held by IBSF's  Employee Stock Ownership
Plan)  and  have  agreed  to vote  them in  favor of the  Merger  Agreement.  In
addition,  HUBCO has voting control over 150,000 of these shares (1.37%) and the
non-director  executive  officers  of IBSF and the  Association  as a group have
voting  control over 301,431 of these  shares  (2.7%),  all of which shares IBSF
expects will be voted in favor of the Merger  Agreement and in the discretion of
the Board of Directors, the Adjournment Proposal.

         The  IBSF  Board of  Directors  has  unanimously  approved  the  Merger
Agreement and unanimously  recommends that holders of IBSF Common Stock vote FOR
the Merger Agreement and FOR the Adjournment Proposal.

    

The Companies

         HUBCO

   

         HUBCO is a New Jersey  corporation  and registered bank holding company
whose  principal  operating   subsidiaries  are  HUB,  a  New   Jersey-chartered
commercial bank, Lafayette American Bank ("Lafayette"),  a Connecticut-chartered
commercial  bank,  and  Bank  of the  Hudson  ("BTH"),  a New  York  state-based
federally-chartered  savings bank. HUBCO's corporate  headquarters is located at
1000 MacArthur  Boulevard,  Mahwah, New Jersey 07430 and its telephone number is
(201)  236-2600.  HUB's  corporate  headquarters  is located at 3100  Bergenline
Avenue,  Union City, New Jersey 07084.  Lafayette's  corporate  headquarters  is
located  at 1000  Lafayette  Boulevard,  Bridgeport,  Connecticut  06604.  BTH's
corporate  headquarters  is  located at 249 Main  Mall,  Poughkeepsie,  New York
12601.

         HUB is a full-service  commercial bank which primarily serves small and
mid-sized  businesses and consumers  through 74 branches in northern New Jersey.
Lafayette   is  a   full-service   commercial   bank  which   serves   primarily
small-to-medium-sized  business firms as well as individuals  through 39 banking
offices located mainly in Fairfield,  Hartford, Middlesex and New Haven counties
in Connecticut.  On April 24, 1998, HUBCO acquired Poughkeepsie  Financial Corp.
("PFC")  and  PFC's  subsidiary,  BTH  became  HUBCO's  New  York-based  banking
subsidiary. On May 29, 1998, HUBCO acquired MSB Bancorp, Inc. ("MSB") and merged
MSB's subsidiary, MSB Bank into BTH. BTH is a community savings bank serving the
Mid-Hudson  Valley area of New York  through 32 branches  in  Dutchess,  Orange,
Putnam  and  Rockland  Counties,  as well as six  residential  loan  origination
offices in five New York counties and New Jersey.  HUBCO anticipates  converting
BTH into a state-chartered  commercial bank at some point in the future. On June
24, 1998 HUBCO  completed  the  purchase of 21 branches of First Union  National
Bank located in New Jersey and  Connecticut  with deposits of $242.9  million in
the aggregate (the "Completed Branch Purchase").  The completed  acquisitions of
PFC, MSB and the Completed Branch Purchase are collectively  referred to in this
Proxy Statement-Prospectus as the "Recently Completed Acquisitions." As of March
31, 1998,  (prior to the  consummation of the Recently  Completed  Acquisitions)
HUBCO had consolidated assets of $3.05 billion,  consolidated  deposits of $2.45
billion and consolidated stockholders' equity of $200.3 million. Based on assets
as of March 31, 1998,  HUBCO was the fourth largest  commercial  banking company
headquartered in New Jersey.

         As of the date of this Proxy  Statement-Prospectus,  HUBCO has  pending
the acquisitions of Dime Financial Corp. ("DFC") and Community Financial Holding
Corporation  ("CFHC") and the  purchase of two  additional  branches  from First
Union  National  Bank  (the  "Pending  Branch  Purchase").  DFC  is  the  parent
corporation of The Dime Savings Bank of  Wallingford,  Connecticut  ("Dime"),  a
bank  headquartered in Wallingford,  Connecticut which had 11 branches and $1.01
billion  in assets as of March  31,  1998.  CFHC is the  parent  corporation  of
Community National Bank of New Jersey ("CNB"), a bank headquartered in Westmont,
New  Jersey  which had 8 branches  and $159.4  million in assets as of March 31,
1998. The Pending  Branch  Purchase  represents the  acquisition of two branches
from First Union  National Bank located in New York with deposits of $25 million
in the  aggregate.  The  pending  acquisitions  of DFC and CFHC and the  Pending
Branch Purchase are collectively referred to in this Proxy  Statement-Prospectus
as the "Pending Acquisitions."

         On June 19 1998, HUBCO issued $50,000,000 aggregate principal amount of
7.65% Capital  Securities  using HUBCO  Capital  Trust II, a statutory  business
trust formed under the laws of the State of Delaware  (the  "Recently  Completed
Trust Preferred Issuance").  The net proceeds of the offering are expected to be
used for general corporate purposes,  including acquisition  opportunities which
may arise from time to time.

         HUBCO's  strategy is to enhance  profitability  and build  market share
through both internal  growth and  acquisitions.  Assuming  consummation  of all
acquisitions  pending as of the date of this Proxy  Statement-Prospectus,  HUBCO
will have completed over 25  acquisitions  since 1990, and HUBCO will have added
over 140  branches  and over $6  billion  in assets  through  acquisitions  this
decade. HUBCO expects to continue its acquisition strategy. HUBCO is continually
evaluating  acquisition   opportunities  and  frequently  conducts  discussions,
certain  financial  analyses and due diligence  activities  in  connection  with
possible acquisitions.  As a result, acquisition discussions and, in some cases,
negotiations  frequently take place and future acquisitions involving cash, debt
or equity securities can be expected. Acquisitions typically involve the payment
of a premium over book and market values, and therefore some dilution of HUBCO's
book  value and net income per  common  share may occur in  connection  with any
future  transactions  (as well as the Recently  Completed  Acquisitions  and the
Pending  Acquisitions).  From time to time,  HUBCO may issue new  equity or debt
securities to fund its  acquisition  plans or for other  purposes.  In the past,
HUBCO has  successfully  managed its  acquisitions to improve its core earnings.
However there can be no assurance that HUBCO will continue to effectively manage
the risks  involved.  If  acquisitions  are not managed  effectively or acquired
institutions  are  not  assimilated  efficiently,  HUBCO's  business,  financial
condition, and results of operations may be adversely impacted.

    

         IBSF

        IBSF  is a New  Jersey  corporation  and  the  sole  shareholder  of the
Association,  which converted to the stock form of organization in October 1994.
The only significant  assets of IBSF are its investments in the capital stock of
the  Association,  its loan to IBSF's employee stock ownership plan, and certain
U.S.  Government Agency  securities and  interest-bearing  deposits.  References
herein to IBSF include the Association unless otherwise noted.  IBSF's corporate
headquarters  is located at 1909 E. Route 70, Cherry Hill, New Jersey 08003.  As
of March 31, 1998, IBSF had consolidated assets of $752.1 million,  consolidated
deposits  of $575.2  million  and  consolidated  stockholders'  equity of $130.5
million.

         The  Association  is a New  Jersey  chartered  stock  savings  and loan
association  which  conducts  business  from nine  offices  located  in  Camden,
Burlington and Gloucester  Counties,  New Jersey.  The Association's  operations
date  back to 1890.  The  Association's  deposits  are  insured  by the  Savings
Association  Insurance Fund ("SAIF") of the FDIC to the maximum extent permitted
by law.

The Merger

         Description of the Merger; Closing Date; Effective Time

         In the Merger,  IBSF will be merged with and into HUBCO,  with HUBCO as
the surviving  entity. A closing under the Merger Agreement (the "Closing") will
occur on a date (the "Closing  Date") to be determined by HUBCO and set forth in
a notice (the  "Closing  Notice") to IBSF.  The Closing Date  specified by HUBCO
must be at least five business days after the date of the Closing Notice, but no
less than seven and no more than ten  business  days after the  satisfaction  or
waiver of the conditions to  consummation of the Merger (other than the delivery
of documents to be  delivered at the  Closing).  The Closing may also be set for
another  day  mutually  agreed to by HUBCO and  IBSF.  HUBCO and IBSF  currently
anticipate  closing  in  the  third  quarter  of  1998.   Simultaneous  with  or
immediately  following the Closing,  HUBCO and IBSF will file a  Certificate  of
Merger with the  Secretary of State of the State of New Jersey.  The Merger will
become  effective at a date and time  following the Closing which HUBCO and IBSF
will  specify  in the  Certificate  of  Merger  (the  "Effective  Time").  If no
Effective  Time is specified in the  Certificate  of Merger,  the Effective Time
will be the time at which the  Certificate  of  Merger is filed.  HUBCO and IBSF
currently  anticipate  that the Effective  Time will be the close of business on
the Closing Date.  The exact Closing Date and Effective  Time are dependent upon
satisfaction  of all  conditions  precedent,  some of which  are not  under  the
control of HUBCO or IBSF.

         Bank Merger

         Immediately  following  the Effective  Time,  the  Association  will be
merged with and into HUB (the "Bank  Merger"),  with HUB as the  surviving  bank
(the "Surviving Bank").

         Consideration

         Upon  completion of the Merger,  each share of IBSF Common Stock (other
than Excluded Shares) will be converted into 0.534 shares (the "Exchange Ratio")
of HUBCO Common Stock.  The Exchange Ratio is subject to standard  anti-dilution
adjustments.  The Exchange  Ratio is also subject to adjustment if IBSF notifies
HUBCO of its intent to terminate  the Merger  Agreement  under  certain  special
circumstances  and HUBCO  overrides the  termination  by increasing the Exchange
Ratio in accordance with a formula set forth in the Merger  Agreement.  See "THE
PROPOSED MERGER -- Termination Events."

         Conversion of IBSF Options

         IBSF has  outstanding  a number of options to  purchase  shares of IBSF
Common Stock  ("IBSF  Options")  which were  granted to optionees  ("Optionees")
pursuant to the IBSF 1995 Stock Option Plan (the "IBSF Stock  Option  Plan") and
the option grant agreements thereunder (the "Option Grant Agreements"). Pursuant
to the Merger  Agreement,  HUBCO has agreed to honor the  provisions of the IBSF
Stock Option Plan and the Option Grant  Agreements,  including those relating to
vesting and conversion in connection with a change in control of IBSF.  Pursuant
to the Merger  Agreement,  each Stock Option  outstanding  at the Effective Time
(each a "Continuing  Stock Option") will be converted into an option to purchase
HUBCO  Common  Stock,  wherein (i) the right to  purchase  shares of IBSF Common
Stock pursuant to the  Continuing  Stock Option will be converted into the right
to purchase  that same number of shares of HUBCO Common Stock  multiplied by the
Exchange  Ratio,  (ii) the option exercise price per share of HUBCO Common Stock
will be the previous  option  exercise  price per share of the IBSF Common Stock
divided by the  Exchange  Ratio,  and (iii) in all other  material  respects the
option  will be  subject  to the same  terms  and  conditions  as  governed  the
Continuing  Stock  Option on which it was  based,  including  the length of time
within which the option may be exercised (which will not be extended except that
the  holder  of a Stock  Option  who  continues  in the  service  of  HUBCO or a
subsidiary of HUBCO will not be deemed to have  terminated  service for purposes
of determining  the Continuing  Stock Option exercise  period).  Shares of HUBCO
Common Stock issuable upon exercise of Continuing  Stock Options will be covered
by an effective  registration statement on Form S-8, and HUBCO has agreed to use
its  reasonable  best  efforts  to file a  registration  statement  on Form  S-8
covering such shares as soon as possible after the Effective Time.

         Cash  in  Lieu  of  Fractional   Shares;   Median   Pre-Closing  Price;
Determination Date

         No  fractional  shares of HUBCO Common Stock will be issued in exchange
for IBSF Common Stock.  Instead,  holders of IBSF Common Stock will receive from
HUBCO cash equal to their  fractional  share  interest  multiplied by the Median
Pre-Closing Price of HUBCO Common Stock,  without interest.  All shares of HUBCO
Common Stock to be issued to a holder of IBSF Common Stock will be aggregated to
constitute  as many whole  shares as possible  before  determining  the person's
fractional  share  interest.  "Median  Pre-Closing  Price" will be determined by
taking the price half-way  between the closing prices left after  discarding the
four lowest and four  highest  closing  prices of HUBCO  Common Stock during the
ten-trading  day period ending on the  Determination  Date.  The  "Determination
Date" will be the later of (i) the day the parties receive final bank regulatory
approval for the Merger and so notify each other or (ii) the date of the Meeting
to which this Proxy Statement relates.

         Termination Rights

   

         The Merger  Agreement  may be  terminated  by either  IBSF or HUBCO if,
among other  reasons,  the Effective  Time has not occurred by December 31, 1998
other than due to failure of the  terminating  party to perform its  obligations
under the Merger  Agreement.  The Merger  Agreement may be terminated by IBSF if
IBSF's  Board  of  Directors  approves  another  acquisition  transaction  after
determining,  upon advice of counsel, that approval is necessary in the exercise
of its  fiduciary  obligations  under  applicable  laws.  In addition,  IBSF may
terminate the Merger Agreement if both (x) the Median Pre-Closing Price of HUBCO
Common  Stock on the  Determination  Date is less than  $31.82,  and (y) (i) the
quotient obtained by dividing the Median Pre-Closing Price of HUBCO Common Stock
on the  Determination  Date by the  HUBCO  Common  Stock  Closing  Price  on the
Starting  Date (as  defined  below) is less than (ii) the  quotient  obtained by
dividing  the Index Price (as defined  below) on the  Determination  Date by the
Index Price on the Starting Date and subtracting 0.10 from the quotient. If both
conditions  (x) and (y)  exist,  and the  IBSF  Board  of  Directors  elects  to
terminate the Merger Agreement,  such termination will not occur if HUBCO elects
to increase the  Exchange  Ratio to a number  calculated  pursuant to the Merger
Agreement.  The  "Starting  Date"  is  April  1,  1998,  the  day  after  public
announcement of the Merger  Agreement.  The "Index Price" on a particular day is
the KBW 50 Index  (an  index of bank  stocks)  for that day,  as  published  the
following business day.

    


         Certain Federal Income Tax Consequences

         HUBCO's and IBSF's obligations to consummate the Merger are conditioned
upon, among other things,  the receipt of an opinion of Pitney,  Hardin,  Kipp &
Szuch,  counsel to HUBCO,  dated the Closing Date, to the effect that the Merger
will  qualify as a  tax-free  reorganization  as  defined in Section  368 of the
Internal  Revenue Code of 1986,  as amended (the  "Code").  While HUBCO and IBSF
each has the contractual right to waive this condition to closing,  neither will
do so.  In  connection  with the  Registration  Statement  of which  this  Proxy
Statement is a part,  counsel to HUBCO has  delivered  its opinion to the effect
that the Merger will qualify as a tax-free  reorganization as defined in Section
368 of the Code.

         Accounting Treatment of the Merger

         The Merger is expected to be  accounted  for as a pooling of  interests
for financial reporting purposes,  and each party's obligation to consummate the
Merger is conditioned  upon HUBCO's receipt of assurances from Arthur  Andersen,
LLP, HUBCO's independent  accountants that the Merger will be so treated.  Under
the  pooling-of-interests  method  of  accounting,  IBSF's  historical  basis of
assets,  liabilities and  stockholders'  equity will be retained by HUBCO as the
surviving entity, and the combined entity's  consolidated  financial  statements
will be restated  retroactively  to reflect the  combined  financial  condition,
results of operations  and cash flows as if HUBCO and IBSF had been combined for
all periods presented.

         Required Regulatory Approvals

         Consummation  of the Merger is subject to prior  receipt of approval of
the  Merger by FDIC and the New Jersey  Department  of  Banking  (the  "NJDOB").
Applications  for FDIC and NJDOB  approval  have been filed,  and HUBCO and IBSF
anticipate receiving such approvals. However, there can be no assurance that the
approvals will be granted,  that they will be granted on a timely basis, or that
they will be granted without conditions unacceptable to HUBCO or IBSF.

         Conditions to the Merger

         There are a number of conditions to completion of the Merger, including
receipt of bank  regulatory  approval;  approval of the Merger  Agreement by the
IBSF shareholders; an opinion of Pitney, Hardin, Kipp & Szuch, counsel to HUBCO,
that the Merger will result in a tax-free  reorganization;  assurances  to HUBCO
from its  independent  accountants  that the Merger will be  accounted  for as a
pooling of  interests;  and certain  other  conditions  usual and  customary  in
transactions similar to the Merger.

         Exchange of Certificates

         Promptly  after the Effective  Time,  the Exchange Agent for HUBCO will
send IBSF  shareholders  letters of transmittal and  instructions for exchanging
their stock  certificates  for  certificates  representing  HUBCO Common  Stock.
HOLDERS OF IBSF COMMON STOCK SHOULD NOT SEND IN THEIR STOCK  CERTIFICATES  UNTIL
THEY RECEIVE INSTRUCTIONS FROM THE EXCHANGE AGENT.

         Fairness Opinion

   

         Ryan, Beck & Co., Inc. ("Ryan,  Beck") has rendered its oral opinion to
the IBSF Board of  Directors  on March 31,  1998,  subsequently  confirmed  by a
formal  written  opinion  dated as of the same date,  and rendered an additional
formal written updated opinion dated July 10, 1998 (the "Opinion"),  that, as of
the respective  dates of such opinions and subject to the  assumptions set forth
therein,  the Exchange  Ratio is fair to the holders of IBSF Common Stock from a
financial  point of view.  For  information  concerning  the  matters  reviewed,
assumptions made and factors  considered by Ryan, Beck, see "THE PROPOSED MERGER
- -- Opinion of Financial  Advisor" and Appendix C to this Proxy Statement,  which
sets forth a copy of Ryan,  Beck's written fairness opinion dated July 10, 1998.
Holders of IBSF Common Stock are urged to, and should,  read such opinion in its
entirety.

    

         No Solicitation by IBSF of Alternative Transactions

         Pursuant  to the Merger  Agreement,  IBSF has agreed  that it will not,
directly or indirectly, encourage or solicit or hold discussions or negotiations
with, or provide any information to, any person other than HUBCO  concerning any
merger or similar acquisition transactions involving IBSF or the Association (an
"Acquisition  Transaction"),  except  that IBSF may enter  into  discussions  or
negotiations or provide  information in connection with an unsolicited  possible
Acquisition Transaction if the Board of Directors of IBSF, after consulting with
counsel,  determines in the exercise of its fiduciary responsibilities that such
action  should be so  taken.  This  restriction,  along  with the  Stock  Option
Agreement described in the following paragraph, may be considered a deterrent to
other potential acquisitions of control of IBSF.

         Stock Option to HUBCO for IBSF Shares

         HUBCO and IBSF entered into a Stock Option  Agreement dated as of March
31, 1998 (the "Stock Option  Agreement") in connection  with the  negotiation by
HUBCO and IBSF of the Merger Agreement.  Pursuant to the Stock Option Agreement,
IBSF has  granted  to HUBCO an option  (the  "Option"),  exercisable  only under
certain  limited  and  specifically  defined  circumstances  (none of which  has
occurred as of the date  hereof),  to purchase up to  2,700,000  authorized  but
unissued shares of IBSF Common Stock,  representing upon issuance  approximately
19.8% of the shares of IBSF Common  Stock,  for an exercise  price of $18.00 per
share.  HUBCO does not have any voting rights with respect to the shares of IBSF
Common Stock subject to the Option prior to exercise of the Option. Acquisitions
of IBSF Common  Stock  pursuant  to  exercise of the option  would be subject to
prior regulatory approval under certain circumstances.

         The Stock  Option  Agreement  is  attached to this Proxy  Statement  as
Appendix B hereto. If certain specifically  enumerated "Triggering Events" occur
and the Merger is not  consummated,  HUBCO would recognize a gain on the sale of
the shares of IBSF Common Stock received  pursuant to the exercise of the Option
if such shares of IBSF  Common  Stock were sold at prices  exceeding  $18.00 per
share.  The  ability  of  HUBCO to  exercise  the  Option  and to cause up to an
additional  2,700,000 shares of IBSF Common Stock to be issued may be considered
a deterrent to other  potential  acquisitions  of control of IBSF,  even if such
potential acquiror were prepared to pay a higher price per share for IBSF Common
Stock,  as it is likely to  increase  the cost of an  acquisition  of all of the
shares of IBSF Common Stock which would then be outstanding. The exercise of the
option  by  HUBCO  may  also  make  pooling-of-interests   accounting  treatment
unavailable to a subsequent acquiror.

         Interests of Certain Persons in the Merger

   

         The Merger Agreement provides that Joseph M. Ochman, Sr., the Chairman,
President and Chief  Executive  Officer of IBSF, will be appointed as a director
of the Surviving Bank and Chairman of the Southern New Jersey  Advisory  Council
of the Surviving  Bank at the Closing.  The Merger  Agreement also provides that
Mr. Ochman will receive a consulting contract for services to be rendered during
a transitional  period.  HUBCO also agreed to honor existing written  employment
and severance agreements with officers and employees of IBSF and the Association
and the Excess Benefit Plan for Mr.  Ochman.  Mr. Ochman will receive a lump sum
cash severance payment together with other continuing benefits.

    

         Certain  employees of IBSF or the Association  (including two executive
officers  other than Mr. Ochman) will receive  "retention"  bonuses in the event
the  employee  remains  an  employee  of IBSF  or the  Association  through  the
Effective  Time (or the subsequent  systems  conversion in certain  cases).  The
retention bonuses will not exceed an aggregate of $150,000.

         All  unvested  stock  options and  restricted  stock awards held by the
directors,  officers and employees of IBSF and the  Association  (including  Mr.
Ochman) will  accelerate and become fully vested as of the Effective  Time. Such
stock  options will be  converted  into stock  options to purchase  HUBCO Common
Stock and the  holders of the  restricted  stock  awards  that  accelerate  will
receive HUBCO Common Stock based upon the Exchange Ratio.

         HUBCO has agreed to indemnify the  directors,  officers,  employees and
agents of IBSF for a period of six years after the Effective Time to the fullest
extent which IBSF would have been  permitted  to do so and to provide  liability
insurance to IBSF's  officers and  directors for a period of six years after the
Effective Time.

         For further details regarding the foregoing, see "THE PROPOSED MERGER -
Interests of Certain Persons in the Merger."

         Differences in Shareholders' Rights

         Each of IBSF and HUBCO is a business corporation incorporated under the
New  Jersey  Business  Corporation  Act  (the  "NJBCA").   The  rights  of  IBSF
shareholders  are  currently  governed  by the NJBCA and IBSF's  certificate  of
incorporation  and bylaws.  At the Effective  Time, each IBSF  shareholder  will
become a shareholder of HUBCO. The rights of HUBCO  shareholders are governed by
the NJBCA and HUBCO's certificate of incorporation and by-laws.

         No Dissenters' Rights

         Under the  NJBCA,  holders of IBSF  Common  Stock are not  entitled  to
dissenters' rights of appraisal in connection with the Merger.

                      SELECTED CONSOLIDATED FINANCIAL DATA

   

         The  following  tables  set  forth  selected  historical   consolidated
financial  information  (audited and  unaudited) for both HUBCO and IBSF for the
periods  indicated.  The  financial  information  for HUBCO has been restated to
include the effects of the merger with The Bank of  Southington  ("TBOS")  which
was  consummated  on January 12, 1998 and has been accounted for as a pooling of
interests.  The tables have been derived from, and should be read in conjunction
with, the selected consolidated  financial data of HUBCO and IBSF, including the
related notes thereto, delivered with or incorporated by reference in this Proxy
Statement-Prospectus. See "INFORMATION DELIVERED AND INCORPORATED BY REFERENCE."

         HUBCO has filed a Current Report on Form 8-K with the Commission  which
contains  supplemental  financial  information  of  HUBCO  for the  years  ended
December 31, 1997,  1996 and 1995 which has been restated to include the effects
of the Recently Completed Acquisitions, which were accounted for as a pooling of
interests.  The selected  consolidated  financial data of HUBCO included in this
Proxy  Statement-Prospectus  is not restated to reflect the  Recently  Completed
Acquisitions or the Recently  Completed  Trust  Preferred  Issuance and does not
reflect the Pending  Acquisitions.  The historical  amounts  presented in future
financial   statements   of  HUBCO   for   periods   reported   in  this   Proxy
Statement-Prospectus will differ and in certain cases, will differ materially as
a result of the effects of  accounting  for the Merger,  the Recently  Completed
Acquisitions  and  certain of the Pending  Acquisitions,  when  consummated,  as
pooling  of  interests.  See  "CERTAIN  INFORMATION  REGARDING  HUBCO  -  Recent
Developments."

         IBSF  shareholders  are not assured of receiving  any  specific  market
value of HUBCO Common  Stock.  The price of HUBCO Common Stock at the  Effective
Time may be higher or lower than the Median Pre-Closing Price, and may be higher
or  lower  than  the  market  price at the  time of  entering  into  the  Merger
Agreement, the time of mailing this Proxy Statement-Prospectus or at the time of
the Meeting. IBSF SHAREHOLDERS ARE URGED TO OBTAIN CURRENT MARKET QUOTATIONS FOR
THE HUBCO COMMON STOCK AND THE IBSF COMMON STOCK.

Limitations on Dividends Under the Merger Agreement

         The Merger  Agreement  prohibits IBSF from declaring,  setting aside or
paying any dividend or other distribution on its capital stock, except that IBSF
may pay dividends on the IBSF Common Stock in a quarterly  amount equal to $0.10
per share.

Dividend Limitations on HUBCO

         The holders of HUBCO  Common  Stock are  entitled to receive  dividends
when and if  declared  by  HUBCO's  Board  of  Directors  out of  funds  legally
available  therefor.  HUBCO has paid regular cash  dividends on its common stock
since its inception in 1982. The HUBCO Series B Convertible Preferred Stock (the
"HUBCO Series B Preferred Stock") also is entitled to receive dividends when and
if  declared  by  HUBCO's  Board of  Directors  out of funds  legally  available
therefor.  HUBCO  has no  obligation  to pay  dividends  on the  HUBCO  Series B
Preferred  Stock  regardless  of any  dividends  which  may be paid on the HUBCO
Common Stock. The primary source for HUBCO's dividends is dividends from HUBCO's
banking subsidiaries to HUBCO, the payment of which is regulated.  Under the New
Jersey Banking Act of 1948, as amended (the "NJBA"),  HUB may pay dividends only
out of retained  earnings,  and only out of surplus to the extent  that  surplus
exceeds 50% of stated capital. Under the Banking Law of Connecticut (the "CBL"),
Lafayette  may pay  dividends  only from its net  profits,  and the total of all
dividends  in any  calendar  year may not (unless  specifically  approved by the
Commissioner of the  Connecticut  Department of Banking) exceed the total of its
net profits of that year combined with its retained net profits of the preceding
two years.  The FDIC has the authority to prohibit a  state-chartered  bank from
engaging  in conduct  which,  in the FDIC's  opinion,  constitutes  an unsafe or
unsound banking practice. Under certain circumstances, the FDIC could claim that
the  payment  of a  dividend  or  other  distribution  by a  bank  to  its  sole
shareholder  constitutes an unsafe or unsound practice.  Under the Office of the
Thrift  Supervision  Regulations  (the "OTSR"),  BTH may pay  dividends up to an
amount equal to 100% of its net income to date during the calendar year plus the
amount that would reduce by one-half its surplus  capital ratio at the beginning
of the calendar  year or up to an amount equal to 75% of its net income over the
most recent four-quarter period, provided in each case that if immediately after
giving effect to such proposed dividend (on a pro forma basis), BTH's capital is
equal to or greater than the amount of its regulatory capital requirement.

                    PRO FORMA CONDENSED FINANCIAL INFORMATION

   

         The  following  tables  present  certain pro forma  unaudited  combined
condensed financial  information from the pro forma unaudited combined condensed
statements of income for the three month period ended March 31, 1998 and for the
years  ended  December  31,  1997,  1996 and 1995,  and the pro forma  unaudited
combined condensed balance sheet at March 31, 1998. The HUBCO and IBSF pro forma
combined financial  information gives effect to HUBCO's proposed  acquisition of
IBSF in a  transaction  accounted  for as a  pooling  of  interests,  as if such
transaction  had been  consummated for statement of income purposes on the first
day of the applicable  periods and for balance sheet purposes on March 31, 1998.
The pro forma  information  assumes an Exchange  Ratio of 0.534  shares of HUBCO
Common Stock for each share of IBSF Common Stock outstanding.

         The  pro  forma  information  is  based  on  the  historical  financial
statements  of HUBCO,  subject  to the  restatement  and pro  forma  adjustments
described  below.  The  financial  information  for HUBCO has been  restated  to
include the effects of the merger with TBOS which was consummated on January 12,
1998 and has  been  accounted  for as a  pooling  of  interests.  The  financial
information for HUBCO has also been adjusted to give pro forma effect to the PFC
and MSB mergers,  which closed on April 24 and May 29, 1998,  respectively,  and
which  were  accounted  for as  pooling of  interests.  The pro forma  financial
information of HUBCO is not restated to reflect the Completed Branch Purchase or
the Recently Completed Trust Preferred Issuance and does not reflect the Pending
Acquisitions. The historical amounts presented in future financial statements of
HUBCO for periods reported in this Proxy Statement-Prospectus will differ and in
certain cases,  will differ  materially as a result of the effects of accounting
for the Merger and certain of the Pending  Acquisitions,  when  consummated,  as
pooling  of  interests.  See  "CERTAIN  INFORMATION  REGARDING  HUBCO  -  Recent
Developments."

         The  pro  forma  information  is  based  on  the  historical  financial
statements of IBSF.  HUBCO's fiscal year ends December 31 and IBSF's fiscal year
ends September 30, 1997, 1996 and 1995,  respectively.  In the following  table,
financial  data for the fiscal  years ended  December  31,  1997,  1996 and 1995
include IBSF financial data for the 12 months ended September 30, 1997, 1996 and
1995, respectively, and information regarding HUBCO is presented consistent with
the fiscal year of HUBCO ended December 31. The information for the three months
ended March 31, 1998 is based on the respective  historical  unaudited financial
statements  of IBSF  and  HUBCO  (subject  to the  restatement  and  adjustments
discussed above).

         The pro forma financial information does not give effect to anticipated
cost savings net of expected Merger related expenses and restructuring charges.

         The summary unaudited pro forma financial information should be read in
conjunction  with the pro forma  financial  information  and the  related  notes
thereto  presented  elsewhere  in this  Proxy  Statement  and  the  consolidated
financial  statements and related notes, as well as the historical and pro forma
information  for PFC and  MSB,  all  incorporated  by  reference  in this  Proxy
Statement.  The pro  forma  information  is not  necessarily  indicative  of the
results of  operations  which  would  have been  achieved  had the  Merger  been
consummated as of the beginning of the periods for which such data are presented
and should not be  construed  as being  representative  of future  periods.  The
financial  information  also  does  not  reflect  one-time  merger  related  and
restructuring  charges  which either have been or will be incurred in connection
with the Merger and the Recently Completed and Pending Acquisitions.

                       ACTUAL AND PRO FORMA PER SHARE DATA

   

         The  following  table sets forth per share data  relating to dividends,
net income and book value of HUBCO Common Stock and IBSF Common  Stock,  both on
an actual  (historical) basis and on a pro forma combined basis, as adjusted for
the Prior Stock  Dividends.  The actual per share data has been derived from the
consolidated financial statements of HUBCO and IBSF, respectively,  incorporated
by reference  herein.  The financial  information for HUBCO has been restated to
include the effects of the merger with TBOS which was consummated on January 12,
1998 and has  been  accounted  for as a  pooling  of  interests.  The  financial
information for HUBCO has also been adjusted to give pro forma effect to the PFC
and MSB mergers,  which closed on April 24 and May 29, 1998,  respectively,  and
which were accounted for as pooling of interests. See "INFORMATION DELIVERED AND
INCORPORATED BY REFERENCE."

         The pro forma unaudited book value per share data at March 31, 1998 and
at December 31, 1997 and the pro forma  unaudited  net income per share data for
the three month period ended March 31, 1998 and for the years ended December 31,
1997,  1996 and 1995 have been  derived  from the pro forma  unaudited  combined
condensed  financial  statements  of HUBCO and IBSF,  giving  effect to  HUBCO's
acquisition  of IBSF  accounted for as a pooling of interests.  In the following
table,  financial  data for the fiscal years ended  December 31, 1997,  1996 and
1995 include IBSF  financial  data for the 12 months ended  September  30, 1997,
1996,  and 1995,  respectively,  and  information  regarding  HUBCO is presented
consistent with the fiscal year of HUBCO ended December 31, 1997, 1996 and 1995.
The  information  for the three  months  ended  March  31,  1998 is based on the
respective  historical  unaudited  financial  statements of HUBCO  (restated and
adjusted) and IBSF. Pro forma  unaudited per share amounts have been  determined
based on the assumptions set forth in the pro forma combined condensed unaudited
financial  statements  presented  elsewhere  herein.  See "PRO  FORMA  FINANCIAL
INFORMATION."  The pro forma  financial  information  of HUBCO  included in this
Proxy  Statement-Prospectus  is not  restated  to reflect the  Completed  Branch
Purchase or the Recently Completed Trust Preferred Issuance and does not reflect
the Pending  Acquisitions.  The historical amounts presented in future financial
statements of HUBCO for periods reported in this Proxy Statement-Prospectus will
differ and in certain cases,  will differ  materially as a result of the effects
of  accounting  for the Merger and  certain of the  Pending  Acquisitions,  when
consummated, as pooling of interests. See "CERTAIN INFORMATION REGARDING HUBCO -
Recent Developments."

         The actual,  pro forma and pro forma equivalent per share data included
in the table below should be read in conjunction  with the financial  statements
of HUBCO and IBSF, as well as the historical and pro forma  information  for PFC
and MSB,  incorporated by reference herein and the pro forma combined  condensed
financial   statements  of  HUBCO  and  IBSF  presented  elsewhere  herein.  See
"INFORMATION  DELIVERED AND  INCORPORATED BY REFERENCE" and "PRO FORMA FINANCIAL
INFORMATION."  The pro forma  information is not  necessarily  indicative of the
results of  operations  which  would  have been  achieved  had the  Merger  been
consummated as of the beginning of the periods for which such data are presented
and should not be  construed  as being  representative  of future  periods.  The
financial  information  also  does  not  reflect  one-time  merger  related  and
restructuring  charges  which either have been or will be incurred in connection
with the Merger and Recently Completed and Pending Acquisitions.

                                  INTRODUCTION

         This Proxy Statement  solicits,  on behalf of the Board of Directors of
IBS Financial Corp. ("IBSF"),  approval by the holders of shares of common stock
of IBSF,  $.01 par value per share ("IBSF Common  Stock"),  of the Agreement and
Plan of Merger, dated as of March 31, 1998 (the "Merger Agreement") among HUBCO,
Inc. ("HUBCO"), HUBCO's New Jersey bank subsidiary,  Hudson United Bank ("HUB"),
IBSF and IBSF's principal  subsidiary,  Inter-Boro  Savings and Loan Association
(the "Association").  Pursuant to the Merger Agreement, IBSF will be merged with
and into HUBCO (the "Merger"),  with HUBCO as the surviving corporation.  A copy
of the Merger  Agreement  is  attached  as  Appendix A to this Proxy  Statement.
Approval of a motion to adjourn the meeting if there are not  sufficient  shares
voted in favor of the Merger Agreement is also being solicited.

         Upon completion of the Merger,  each share of IBSF Common Stock,  other
than Excluded  Shares (as defined  below),  will be converted  into 0.534 shares
(the  "Exchange  Ratio") of common stock of HUBCO,  no par value ("HUBCO  Common
Stock").  Cash will be paid in lieu of fractional  shares. The Exchange Ratio is
subject  to  adjustment  in  certain  circumstances,  as set forth in the Merger
Agreement and more fully described in this Proxy Statement.

         IBSF has  outstanding  a number of options to  purchase  shares of IBSF
Common Stock  ("IBSF  Options")  which were  granted to optionees  ("Optionees")
pursuant to the IBSF 1995 Stock Option Plan (the "IBSF Stock  Option  Plan") and
the option  grant  agreements  thereunder  (the  "Option  Grant  Agreements").  
Pursuant to the Merger  Agreement,  HUBCO has agreed to honor the  provisions of
the IBSF Stock  Option Plan and the Option  Grant  Agreements,  including  those
relating to vesting and  conversion  in  connection  with a change in control of
IBSF.  Pursuant to the Merger  Agreement,  each Stock Option  outstanding at the
Effective  Time (each a "Continuing  Stock  Option")  will be converted  into an
option to purchase HUBCO Common Stock,  wherein (i) the right to purchase shares
of IBSF Common Stock pursuant to the  Continuing  Stock Option will be converted
into the right to  purchase  that same  number of shares of HUBCO  Common  Stock
multiplied by the Exchange  Ratio,  (ii) the option  exercise price per share of
HUBCO Common Stock will be the previous  option  exercise price per share of the
IBSF Common Stock divided by the Exchange Ratio, and (iii) in all other material
respects the option will be subject to the same terms and conditions as governed
the Continuing Stock Option on which it was based,  including the length of time
within which the option may be exercised (which will not be extended except that
the  holder  of a Stock  Option  who  continues  in the  service  of  HUBCO or a
subsidiary of HUBCO will not be deemed to have  terminated  service for purposes
of determining  the Continuing  Stock Option exercise  period).  Shares of HUBCO
Common Stock issuable upon exercise of Continuing  Stock Options will be covered
by an effective  registration statement on Form S-8, and HUBCO has agreed to use
its  reasonable  best  efforts  to file a  registration  statement  on Form  S-8
covering such shares as soon as possible after the Effective Time.

         All  information  and  statements  contained  in,  delivered  with,  or
incorporated  by  reference  in this Proxy  Statement  with respect to IBSF were
supplied by IBSF, and all information  and statements  contained or incorporated
by reference herein with respect to HUBCO were supplied by HUBCO.


                       CERTAIN INFORMATION REGARDING HUBCO

General

   

         HUBCO is a New Jersey  corporation  and registered bank holding company
whose principal  operating  subsidiaries  are Hudson United Bank ("HUB"),  a New
Jersey-chartered  commercial  bank,  Lafayette  American Bank  ("Lafayette"),  a
Connecticut-chartered  commercial  bank, and Bank of the Hudson  ("BTH"),  a New
York   state-based   federally-chartered   savings   bank.   HUBCO's   corporate
headquarters is located at 1000 MacArthur  Boulevard,  Mahwah,  New Jersey 07430
and its telephone  number is (201)  236-2600.  HUB's  corporate  headquarters is
located at 3100  Bergenline  Avenue,  Union City, New Jersey 07084.  Lafayette's
corporate  headquarters  is located  at 1000  Lafayette  Boulevard,  Bridgeport,
Connecticut  06604.  BTH's  corporate  headquarters is located at 249 Main Mall,
Poughkeepsie, New York 12601.


         HUB is a full-service  commercial bank which primarily serves small and
mid-sized  businesses and consumers  through 74 branches in northern New Jersey.
Lafayette   is  a   full-service   commercial   bank  which   serves   primarily
small-to-medium-sized  business firms as well as individuals  through 39 banking
offices located mainly in Fairfield,  Hartford, Middlesex and New Haven counties
in Connecticut.  On April 24, 1998, HUBCO acquired Poughkeepsie  Financial Corp.
("PFC")  and  PFC's  subsidiary,  BTH  became  HUBCO's  New  York-based  banking
subsidiary. On May 29, 1998, HUBCO acquired MSB Bancorp, Inc. ("MSB") and merged
MSB's subsidiary, MSB Bank into BTH. BTH is a community savings bank serving the
Mid-Hudson  Valley area of New York  through 32 branches  in  Dutchess,  Orange,
Putnam  and  Rockland  Counties,  as well as six  residential  loan  origination
offices in five New York counties and New Jersey.  HUBCO anticipates  converting
BTH into a state-chartered  commercial bank at some point in the future. On June
24, 1998 HUBCO  completed  its  purchase of 21 branches of First Union  National
Bank located in New Jersey,  New York and  Connecticut  with  deposits of $242.9
million in the  aggregate  (the  "Completed  Branch  Purchase").  The  completed
acquisitions  of PFC, MSB and the  Completed  Branch  Purchase are  collectively
referred  to in  this  Proxy  Statement-Prospectus  as the  "Recently  Completed
Acquisitions."  As of March 31, 1998, (prior to the consummation of the Recently
Completed   Acquisitions)  HUBCO  had  consolidated  assets  of  $3.05  billion,
consolidated deposits of $2.45 billion and consolidated  stockholders' equity of
$200.3  million.  Based on  assets as of March 31,  1998,  HUBCO was the  fourth
largest commercial banking company headquartered in New Jersey.

         As of the date of this Proxy  Statement-Prospectus,  HUBCO has  pending
the acquisitions of Dime Financial Corp. ("DFC") and Community Financial Holding
Corporation  ("CFHC") and the  purchase of two  additional  branches  from First
Union  National  Bank  (the  "Pending  Branch  Purchase").  DFC  is  the  parent
corporation of The Dime Savings Bank of  Wallingford,  Connecticut  ("Dime"),  a
bank  headquartered in Wallingford,  Connecticut which had 11 branches and $1.01
billion  in assets as of March  31,  1998.  CFHC is the  parent  corporation  of
Community National Bank of New Jersey ("CNB"), a bank headquartered in Westmont,
New  Jersey  which had 8 branches  and $159.4  million in assets as of March 31,
1998. The Pending  Branch  Purchase  represents the  acquisition of two branches
from First Union  National Bank located in New York with deposits of $25 million
in the  aggregate.  The  pending  acquisitions  of DFC and CFHC and the  Pending
Branch Purchase are collectively referred to in this Proxy  Statement-Prospectus
as the "Pending Acquisitions."

         HUBCO's  strategy is to enhance  profitability  and build  market share
through both internal  growth and  acquisitions.  Assuming  consummation  of all
acquisitions  pending as of the date of this Proxy  Statement-Prospectus,  HUBCO
will have completed over 25  acquisitions  since 1990, and HUBCO will have added
over 140  branches  and over $6  billion  in assets  through  acquisitions  this
decade. HUBCO expects to continue its acquisition strategy. HUBCO is continually
evaluating  acquisition   opportunities  and  frequently  conducts  discussions,
certain  financial  analyses and due diligence  activities  in  connection  with
possible acquisitions.  As a result, acquisition discussions and, in some cases,
negotiations  frequently take place and future acquisitions involving cash, debt
or equity securities can be expected. Acquisitions typically involve the payment
of a premium over book and market values, and therefore some dilution of HUBCO's
book  value and net income per  common  share may occur in  connection  with any
future  transactions.  From time to time,  HUBCO  may  issue new  equity or debt
securities to fund its  acquisition  plans or for other  purposes.  In the past,
HUBCO has  successfully  managed its  acquisitions to improve its core earnings.
However there can be no assurance that HUBCO will continue to effectively manage
the risks  involved.  If  acquisitions  are not managed  effectively or acquired
institutions  are  not  assimilated  efficiently,  HUBCO's  business,  financial
condition,  and results of operations may be adversely impacted.  For additional
information,   see  "AVAILABLE   INFORMATION"  and  "INFORMATION  DELIVERED  AND
INCORPORATED BY REFERENCE."

         On May 29, 1998 HUBCO  completed its acquisition of MSB, a bank holding
company  headquartered  in Goshen,  New York,  by merging MSB into HUBCO and MSB
Bank into BTH,  HUBCO's New York banking  subsidiary (the "MSB Merger").  In the
MSB Merger,  HUBCO issued  2,848,367  shares of HUBCO common stock, no par value
("HUBCO  Common  Stock"),  in the  aggregate.  At March 31, 1998, MSB had $753.7
million in assets.  The MSB Merger  was  treated as a pooling of  interests  for
accounting purposes.

         Poughkeepsie Financial Corp.

         On April 24, 1998,  HUBCO  completed its  acquisition  of PFC and PFC's
banking  subsidiary,  BTH,  by merging  PFC into HUBCO (the "PFC  Merger").  BTH
became HUBCO's New York-based bank subsidiary.  In the PFC Merger,  HUBCO issued
3,481,903  shares of HUBCO Common Stock in the aggregate.  As of March 31, 1998,
PFC had $848.8  million in  assets.  The PFC Merger was  treated as a pooling of
interests for accounting purposes.

         Purchase of 21 branches from First Union National Bank

         On June 24, 1998,  HUBCO  completed  the  purchase of 21 branches  from
First Union  National  Bank (the  "Completed  Branch  Purchase")  located in New
Jersey and Connecticut with deposits of $242.9 million, in the aggregate.

         HUBCO  has  filed  with the  Commission  a  Current  Report on Form 8-K
containing  supplemental  financial  information  of HUBCO for the  years  ended
December 31, 1997,  1996 and 1995 which has been restated to include the effects
of the Recently Completed Acquisitions, which were accounted for as a pooling of
interests.  The historical  financial statements of HUBCO included in this Proxy
Statement-Prospectus   are  not  restated  to  reflect  the  Recently  Completed
Acquisitions. The historical amounts presented in future financial statements of
HUBCO for periods reported in this Proxy  Statement-Prospectus  will differ and,
in  certain  cases,  will  differ  materially  as a  result  of the  effects  of
accounting for the Recently  Completed  Acquisitions,  the Merger and certain of
the Pending Acquisitions, when consummated, as pooling of interests.

         Pending    Acquisitions:    As   of   the    date   of    this    Proxy
Statement-Prospectus,  HUBCO has entered into  definitive  agreements to acquire
the following two financial institutions and the Pending Branch Purchase.

         Dime Financial Corporation

         On  March  31,  1998,  HUBCO,  Lafayette,  DFC and  DFC's  wholly-owned
subsidiary,  Dime signed a definitive  merger  agreement to merge DFC into HUBCO
and Dime into Lafayette (the "DFC Merger").  In the DFC Merger, DFC shareholders
will receive  HUBCO  Common  Stock with an  indicated  value of $38.25 per share
based upon the median price of HUBCO Common Stock in a period immediately before
regulatory  approval  (if the price of HUBCO stock during such period is between
$36.42 and  $41.13).  A maximum  exchange  ratio of 1.05 shares of HUBCO  Common
Stock for each  share of DFC common  stock will apply if HUBCO's  pre-regulatory
approval  price is below $36.43.  A minimum  exchange  ratio of 0.93 shares will
apply if HUBCO's  pre-regulatory  approval price is above $41.13.  DFC is a bank
holding company  headquartered in Wallingford,  Connecticut.  At March 31, 1998,
DFC had $1.01  billion in assets.  The DFC  Merger is  expected  to close in the
third quarter of 1998 and to be treated as a pooling of interests for accounting
purposes.  HUBCO expects to issue approximately 5,510,000 shares of HUBCO Common
Stock in the DFC Merger.

         Community Financial Holding Corporation

         On March 3, 1998, HUBCO, HUB, CFHC and CFHC's wholly-owned  subsidiary,
CNB signed a definitive  merger  agreement to merge CFHC into HUBCO and CNB into
HUB (the "CFHC Merger").  Pursuant to the merger  agreement,  each share of CFHC
common stock will be exchanged for 0.695 shares of HUBCO Common  Stock,  so long
as the median  closing price for HUBCO Common Stock during a pre-closing  period
is not below  $29.00,  unless HUBCO  agrees to increase  the  exchange  ratio to
provide the value which would have been received  based on a $29.00 HUBCO price.
CFHC is a commercial bank holding company headquartered in Westmont, New Jersey.
At March 31,  1998,  CFHC had  $159.4  million  in  assets.  The CFHC  Merger is
expected to close in the third quarter of 1998 and to be treated as a pooling of
interests for accounting purposes.  HUBCO expects to issue approximately 834,000
shares of HUBCO Common Stock in the CFHC Merger.

         Purchase of two branches from First Union National Bank

         HUBCO  anticipates that it will complete the purchase of two additional
branches from First Union National Bank located in New York with deposits of $25

         If all Pending  Acquisitions  and the Merger are consummated and taking
into account the Recently Completed Acquisitions, HUBCO anticipates it will have
at least $6.5 billion in assets and $475 million in stockholders' equity.

         In connection with its acquisitions  which are accounted for as pooling
of interests  transactions,  HUBCO normally incurs  significant  one-time merger
related  and  restructuring  charges and  realizes  significant  operating  cost
savings.  Upon the  announcement  of significant  acquisitions,  HUBCO initially
estimates  one-time  merger  related  and  restructuring  costs,  which are then
reported on the Current  Report on Form 8-K  reporting the  announcement  of the
acquisition. Thereafter, HUBCO does not update or repeat its initial estimate of
such one-time charges.  Rather, HUBCO reports the actual one-time merger related
and  restructuring  charges for the transaction in the earnings  release for the
quarter in which the transaction  closes.  While such one-time charges adversely
effect earnings in the quarter in which a transaction closes, HUBCO also reports
its earnings excluding such one-time charges to allow investors to focus on core
earnings results. See "INCORPORATION OF CERTAIN DOCUMENTS BY REFERENCE."

         At the time of the  announcement  of a significant  transaction,  HUBCO
sometimes  also  provides  estimated  cost  savings but not revenue  enhancement
estimates  for the  acquired  institution.  HUBCO  does not update or repeat its
initial  estimate  of  such  cost  savings.  Historically,  HUBCO  has  realized
significant  cost savings in the  acquisitions it has  consummated,  and thereby
significantly  increased  core  earnings  for the acquired  institutions.  HUBCO
relies on its quarterly earnings releases following  consummation to reflect the
operating efficiencies achieved in its acquisitions.

         In quarters in which one or more pooling  transactions close,  earnings
for that quarter will be adversely effected,  sometimes significantly.  However,
core  earnings,  to a limited extent in the closing  quarter,  and more fully in
subsequent quarters,  will reflect cost savings and revenue  enhancements.  As a
result of consummating  the Recently  Completed  Acquisitions,  HUBCO will incur
material one-time merger related and restructuring charges, which will adversely
affect reported  earnings in the second quarter of 1998. HUBCO also expects that
due to the anticipated closings of the pending acquisitions of DFC, CFHC and the
Merger it will incur material one-time merger related and restructuring  charges
in the third quarter of 1998 which will adversely  affect  reported  earnings in
the third quarter of 1998.

         HUBCO  attempts  to price and  structure  its  acquisitions  to provide
earnings per share accretion,  excluding one time charges, calculated before the
restatement  of  prior  period  results   required  under   pooling-of-interests
accounting treatment.

         On June 19, 1998, HUBCO issued $50,000,000  aggregate  principal amount
of 7.65% Capital  Securities using HUBCO Capital Trust II, a statutory  business
trust formed under the laws of the State of Delaware  (the  "Recently  Completed
Trust Preferred Issuance"). The Capital Securities pay interest semi-annually on
June 15, and December 15. Interest on the Capital  Securities may, at the option
of HUBCO,  be deferred for up to five years.  The Capital  Securities  mature on
February  1, 2027 and are  callable  on or after June 15,  2007,  subject to the
prior  approval of the Board of Governors of the Federal  Reserve System ("FRB")
to the extent necessary at that time. The Capital Securities will be eligible to
qualify  as Tier I capital  under the  capital  guidelines  of the FRB.  A small
portion of the Capital  Securities  will not qualify as Tier I capital until and
unless some of the Pending  Acquisitions and/or the Merger are consummated.  The
net  proceeds of the  offering  are  expected  to be used for general  corporate
purposes, including acquisition opportunities which may arise from time to time.

                       CERTAIN INFORMATION REGARDING IBSF

        IBSF  is a New  Jersey  corporation  and  the  sole  shareholder  of the
Association,  which converted to the stock form of organization in October 1994.
The only significant  assets of IBSF are its investments in the capital stock of
the  Association,  its loan to IBSF's employee stock ownership plan, and certain
U.S.  Government Agency  securities and  interest-bearing  deposits.  References
herein to IBSF include the Association unless otherwise noted.

        The  Association  is a New  Jersey  chartered  stock  savings  and  loan
association  which  conducts  business  from nine  offices  located  in  Camden,
Burlington and Gloucester  Counties,  New Jersey.  The Association's  operations
date back to 1890.  The  Association's  deposits  are insured by the SAIF of the
FDIC to the maximum extent permitted by law.

        IBSF has  traditionally  offered a variety  of savings  products  to its
retail customers.  IBSF invests its funds in U.S.  Government,  U.S.  Government
agency and mortgage-backed  securities and other short-term  investments and has
concentrated  its  lending  activities  on real estate  loans  secured by single
(i.e.,  "one-to-four") family residential properties.  In fiscal 1996, IBSF also
expanded its investment in commercial  real estate loans.  The  commercial  real
estate loans  originated are  collateralized  by small  professional and medical
office buildings,  commercial retail establishments and religious  organizations
in IBSF's market area. In addition and to a lesser  degree,  construction  loans
are originated to construct  primarily  single-family  residences.  In the past,
IBSF has also  purchased  whole  residential  mortgage  loans and  participation
interests in commercial real estate projects located principally in New Jersey.

        During  fiscal 1996,  IBSF began  emphasizing  the  origination  of more
commercial real estate loans in the local marketplace.  In addition, the Company
continued to reduce its liquid  assets by  reinvesting  the proceeds of maturing
investments into  mortgage-backed  securities  generally with maturities of five
and  seven  years.  This  was  designed  to  increase  IBSF's  yield on its loan
portfolio.  During fiscal 1996,  however,  IBSF experienced  heavy repayments of
higher  yielding  residential  loans and  mortgage-backed  securities  that were
reinvested in lower yielding loans and mortgage-backed  securities. As a result,
IBSF's net interest margin was pressured, decreasing to 3.44% for the year ended
September 30, 1996 from 3.77% during fiscal 1995.

        During  fiscal 1997,  IBSF  continued to emphasize  the  origination  of
single-family  residential  loans and  commercial  real estate loans.  IBSF also
continued  to  experience   relatively   heavy  repayments  of  higher  yielding
residential loans and  mortgage-backed  securities that were reinvested in lower
yielding  loans  and  mortgage-backed   securities.   In  addition,  IBSF's  net
interest-earning  assets  declined by  approximately  $20  million,  principally
reflecting the shares of IBSF Common Stock  repurchased  during the fiscal year.
This resulted in a decrease of 30 basis points in IBSF's net interest  margin to
3.14% for the year ended September 30, 1997. The net interest margin for the six
months ended March 31, 1998 was 3.09%.

        Financial highlights of IBSF include:

        o      Profitability.  Net income totaled $5.8 million, $4.5 million and
               $9.9 million for the fiscal years ended September 30, 1997, 1996,
               and  1995,  respectively.  Net  income  during  fiscal  1996  was
               impacted by a one-time  special  assessment of $3.7 million ($2.4
               million after tax) to recapitalize  the SAIF. Net income was $3.1
               million and $2.9  million for the six months ended March 31, 1998
               and 1997, respectively.

        o      Asset  Quality.  Management of IBSF believes that superior  asset
               quality is the key to long-term financial strength.  At March 31,
               1998,  single-family  residential  loans  comprised  87.2% of the
               Association's  total  loan  portfolio.  As of  that  date,  total
               non-performing loans and troubled debt restructurings constituted
               .30% of total loans, and total nonperforming  assets and troubled
               debt restructurings were .09% of total assets.

        o      Capital.  IBSF currently exceeds all minimum  regulatory  capital
               requirements  of the  Office of Thrift  Supervision  ("OTS").  At
               March 31, 1998,  it had  tangible,  core and  risk-based  capital
               ratios of 17.2%, 17.2% and 59.9%, respectively.

        o      Retail  Deposit  Base.  IBSF has nine offices  located in Camden,
               Burlington and  Gloucester  Counties,  New Jersey.  It provides a
               full  range  of  deposit  products  and  other  services  to  its
               customers  through this branch network.  At March 31, 1998, 24.8%
               of the Association's  deposit base of $575.2 million consisted of
               core  deposits,  which  include  passbook,  money  market and NOW
               accounts.

         IBSF as a savings and loan  holding  company is subject to  examination
and  regulation  by the OTS and  NJDOB.  The  Association  is  also  subject  to
examination  and  comprehensive  regulation  by the  NJDOB  and by the OTS.  The
Association is also regulated by the FDIC,  the  administrator  of the SAIF. The
Association is subject to certain reserve requirements  established by the Board
of  Governors  of the  Federal  Reserve  System  ("FRB")  and is a member of the
Federal  Home Loan Bank  ("FHLB")  of New York,  which is one of the 12 regional
banks comprising the FHLB System.


                                   THE MEETING

Purpose of the Meeting

   

         The Meeting will be held on Monday, August 10, 1998 at 11:00 am, at the
Hilton At Cherry Hill, 2349 West Marlton Pike, Cherry Hill, New Jersey 08002. At
the  Meeting,  the holders of IBSF Common  Stock will  consider  and vote on the
approval and adoption of the Merger Agreement, in the discretion of the Board of
Directors of IBSF, approval of the Adjournment Proposal and any other matters as
may  properly  be  brought  before  the  Meeting  and  at  any  adjournments  or
postponements thereof. This Proxy Statement is first being mailed to the holders
of IBSF  Common  Stock on or about July 10, 1998 and is  accompanied  by a proxy
card furnished in connection with the  solicitation of proxies by the IBSF Board
of Directors for use at the Meeting.

    

         The Board of  Directors  of IBSF has  unanimously  approved  the Merger
Agreement  and  recommends  a vote "FOR"  approval  and  adoption  of the Merger
Agreement and "FOR" the approval of the Adjournment Proposal.

Record Date; Voting Rights; Proxies

         The Board of  Directors of IBSF has fixed the close of business on June
12, 1998 as the record  date for  determining  the holders of IBSF Common  Stock
entitled to receive  notice of and to vote at the Meeting (the  "Record  Date").
Only  holders of record of IBSF  Common  Stock at the close of  business on that
date  will  be  entitled  to  vote  at  the  Meeting  or at any  adjournment  or
postponement thereof.

   

         At the close of  business  on the Record  Date,  there were  10,962,116
shares of IBSF Common Stock issued and  outstanding  and entitled to vote at the
Meeting.  Each share of IBSF Common Stock will be entitled to one vote upon each
matter  properly  submitted at the Meeting or at any adjournment or postponement
thereof.

    

         All  properly  executed  proxies  will,  unless such  proxies have been
previously  revoked,  be voted in accordance with the instructions  indicated on
such proxies.  If no  instructions  are indicated  thereon,  such shares will be
voted "FOR" approval and adoption of the Merger Agreement and "FOR" the approval
of the Adjournment Proposal.  The Board of Directors of IBSF is not aware of any
matters  other than as  described  in the Notice of Special  Meeting that are to
come before the Meeting.  If any other matter or matters are properly  presented
for action  before the Meeting,  the persons named in the enclosed form of proxy
will have  discretion  to vote on such  matters  in  accordance  with their best
judgment, unless such authorization is withheld.

         A proxy may be revoked at any time prior to its  exercise by the filing
of a written  notice of revocation  with the Secretary of IBSF, by delivering to
IBSF a duly executed proxy bearing a later date, or by attending the Meeting and
voting in person. However, shareholders whose shares are not registered in their
own names will need appropriate documentation from the holder of record of their
shares  to vote  personally  at the  Meeting.  In  order to  revoke  a proxy,  a
shareholder  must either file a written  notice of  revocation  or duly executed
proxy with:  the IBSF  Corporate  Secretary,  Chiara  Eisennagel,  IBS Financial
Corp.,  1909 E.  Route 70,  Cherry  Hill,  New  Jersey  08003,  telephone  (609)
424-1000, or attend the meeting and vote in person as described above.

         Votes cast by proxy or in person at the Meeting  will be  tabulated  by
the election inspectors appointed for the Meeting, who will determine whether or
not a quorum is present.

         IBSF SHAREHOLDERS  SHOULD NOT FORWARD ANY STOCK CERTIFICATES WITH THEIR
PROXY  CARDS.  IF THE  MERGER  IS  CONSUMMATED,  STOCK  CERTIFICATES  SHOULD  BE
DELIVERED IN ACCORDANCE WITH  INSTRUCTIONS  SET FORTH IN A LETTER OF TRANSMITTAL
WHICH WILL BE SENT TO IBSF SHAREHOLDERS BY THE EXCHANGE AGENT PROMPTLY AFTER THE
EFFECTIVE TIME.

Solicitation of Proxies

         In addition to using the mails,  the directors,  officers and employees
of IBSF may solicit  proxies for the Meeting from  shareholders  personally,  by
telephone or by facsimile.  These officers,  directors and employees will not be
specifically  compensated for their services.  IBSF will also make  arrangements
with  brokerage  firms and other  custodians,  nominees and  fiduciaries to send
proxy  materials to their  principals  and will reimburse such parties for their
expenses in doing so. The cost of  soliciting  proxies  for the Meeting  will be
borne by IBSF.

Quorum

         The  presence,  in  person or by proxy,  of the  holders  of at least a
majority of the total number of shares of IBSF Common Stock  entitled to vote is
necessary to constitute a quorum at the Meeting.  Abstentions  are considered in
determining the presence of a quorum.

Required Vote

         Each share of IBSF Common  Stock will be entitled to one vote upon each
matter  properly  submitted at the Meeting or at any adjournment or postponement
thereof.

         The affirmative  vote of a majority of the votes cast by the holders of
outstanding  shares of IBSF  Common  Stock  entitled  to vote at the  Meeting is
required in order to approve  and adopt the Merger  Agreement.  The  affirmative
vote of the holders of a majority of votes cast  affirmatively  or negatively is
required in order to approve  and adopt the  Adjournment  Proposal.  Abstentions
will not be counted in determining  the vote on the Merger  Agreement and on the
Adjournment   Proposal.    In   addition,    both   proposals   are   considered
"non-discretionary"   for  which  brokers  may  not  vote  unless  they  receive
instructions  from the  beneficial  owner.  Because all of the  proposals at the
Meeting  are  non-discretionary,  there  will be no  "broker  non-votes"  at the
Meeting.

   

         Record  holders of IBSF  Common  Stock at the close of business on June
12, 1998 (the  "Record  Date") are  entitled to vote at the  Meeting.  As of the
Record Date, there were 10,962,116  outstanding shares of IBSF Common Stock held
by  approximately  1,930  holders  of  record.  The  directors  of IBSF  and the
Association  as a group have voting  control over 739,373 of these shares (6.7%)
(excluding  unallocated shares held by IBSF's Employee Stock Ownership Plan) and
have agreed to vote them in favor of the Merger  Agreement.  In addition,  HUBCO
has voting  control over 150,000 of these  shares  (1.37%) and the  non-director
executive  officers of IBSF and the  Association  as a group have voting control
over  301.431 of these shares  (2.7%),  all of which shares IBSF expects will be
voted in favor of the Merger Agreement. HUBCO requested that the directors enter
into this agreement in connection with HUBCO entering into the Merger Agreement.

    

         The  obligations of IBSF and HUBCO to consummate  the Merger  Agreement
are subject,  among other things, to the condition that the Merger Agreement and
the transactions  contemplated  thereby be approved by the requisite vote of the
shareholders of IBSF. See "THE PROPOSED MERGER -- Conditions to the Merger."

         THE MATTERS TO BE CONSIDERED AT THE MEETING ARE OF GREAT  IMPORTANCE TO
THE  SHAREHOLDERS  OF  IBSF.  ACCORDINGLY,  SHAREHOLDERS  ARE  URGED TO READ AND
CAREFULLY  CONSIDER THE INFORMATION  PRESENTED IN THIS PROXY  STATEMENT,  AND TO
COMPLETE,  DATE,  SIGN AND PROMPTLY  RETURN THE  ENCLOSED  PROXY IN THE ENCLOSED
POSTAGE PAID ENVELOPE.


                               THE PROPOSED MERGER

         A copy of the Merger  Agreement is attached as Appendix A to this Proxy
Statement and is  incorporated by reference  herein.  Descriptions of the Merger
and the Merger  Agreement  are  qualified in their  entirety by reference to the
Merger Agreement.

General Description; The Bank Merger

         The Merger Agreement provides that, at the Effective Time, IBSF will be
merged into HUBCO, with HUBCO as the surviving entity (the "Surviving  Entity").
The separate  identity and existence of IBSF will cease upon consummation of the
Merger, and all property, rights, powers and franchises of IBSF will vest in the
Surviving Entity. Immediately following the Effective Time, the Association will
be merged with and into HUB (the "Bank Merger"),  with HUB as the surviving bank
(the "Surviving Bank").

Closing Date; Effective Time

         A closing under the Merger  Agreement (the  "Closing")  will occur on a
date (the  "Closing  Date") to be  determined by HUBCO and set forth in a notice
(the "Closing  Notice") to IBSF.  The Closing Date specified by HUBCO must be at
least five business days after the date of the Closing Notice,  but no less than
seven and no more than ten business days after the satisfaction or waiver of the
conditions to  consummation  of the Merger (other than the delivery of documents
to be  delivered  at the  Closing).  The Closing may also be set for another day
mutually  agreed  to by HUBCO  and IBSF.  HUBCO  and IBSF  currently  anticipate
closing in the third quarter of 1998. Simultaneous with or immediately following
the Closing, HUBCO and IBSF will file a Certificate of Merger with the Secretary
of State of the State of New Jersey.  The Merger will become effective at a date
and time  following  the  Closing  which  HUBCO  and IBSF  will  specify  in the
Certificate of Merger (the "Effective  Time"). If no Effective Time is specified
in the  Certificate of Merger,  the Effective Time will be the time at which the
Certificate  of Merger is filed.  HUBCO and IBSF currently  anticipate  that the
Effective  Time will be the close of  business on the  Closing  Date.  The exact
Closing  Date  and  Effective  Time  are  dependent  upon  satisfaction  of  all
conditions precedent, some of which are not under the control of HUBCO or IBSF.

Consideration

         At the  Effective  Time,  each  outstanding  share of IBSF Common Stock
(except for Excluded  Shares) will be converted  into the right to receive 0.534
shares (the "Exchange Ratio") of HUBCO Common Stock. "Excluded Shares" are those
shares of IBSF Common  Stock which are (i) held by IBSF as treasury  shares,  or
(ii) held by HUBCO or any of its subsidiaries (other than shares held as trustee
or in a fiduciary capacity and shares held as collateral on or in lieu of a debt
previously contracted).

         The Exchange  Ratio is subject to  adjustment  to take into account any
stock  split,  stock  dividend,  reclassification,   recapitalization,   merger,
combination  or exchange  or similar  transaction  by HUBCO with  respect to the
HUBCO Common Stock  occurring  subsequent to March 31, 1998.  The Exchange Ratio
may also be subject to adjustment in connection with provisions  relating to the
termination  of the Merger  Agreement  described  below  under the  caption  "--
Termination Events".

Cash in Lieu of Fractional Shares; Median Pre-Closing Price; Determination Date

         No  fractional  shares of HUBCO Common Stock will be issued in exchange
for any IBSF Common Stock or IBSF Options.  Instead, holders of such IBSF Common
Stock will receive cash equal to the fractional share interest multiplied by the
Median Pre-Closing Price of HUBCO Common Stock, without interest.  All shares of
HUBCO  Common  Stock to be issued to each  holder of IBSF  Common  Stock will be
aggregated  to constitute  as many whole shares as possible  before  determining
such person's fractional share interest.  The "Median Pre-Closing Price" will be
determined by taking the price  half-way  between the closing  prices left after
discarding  the  four  lowest  and  four  highest  closing  prices  in  the  ten
consecutive  trading day period which ends on (and  includes) the  Determination
Date. The  "Determination  Date" is defined in the Merger Agreement as the later
of (i) the day the parties receive final bank regulatory approval for the Merger
and one notifies the other that such approval has been received or (ii) the date
of the Meeting to which this Proxy Statement relates.

Conversion of IBSF Options

         IBSF has  outstanding  a number of options to  purchase  shares of IBSF
Common Stock  ("IBSF  Options")  which were  granted to optionees  ("Optionees")
pursuant to the IBSF 1995 Stock Option Plan (the "IBSF Stock  Option  Plan") and
the option  grant  agreements  thereunder  (the  "Option  Grant  Agreements").  
Pursuant to the Merger  Agreement,  HUBCO has agreed to honor the  provisions of
the IBSF Stock  Option Plan and the Option  Grant  Agreements,  including  those
relating to vesting and  conversion  in  connection  with a change in control of
IBSF.  Pursuant to the Merger  Agreement,  each Stock Option  outstanding at the
Effective  Time (each a "Continuing  Stock  Option")  will be converted  into an
option to purchase HUBCO Common Stock,  wherein (i) the right to purchase shares
of IBSF Common Stock pursuant to the  Continuing  Stock Option will be converted
into the right to  purchase  that same  number of shares of HUBCO  Common  Stock
multiplied by the Exchange  Ratio,  (ii) the option  exercise price per share of
HUBCO Common Stock will be the previous  option  exercise price per share of the
IBSF Common Stock divided by the Exchange Ratio, and (iii) in all other material
respects the option will be subject to the same terms and conditions as governed
the Continuing Stock Option on which it was based,  including the length of time
within which the option may be exercised (which will not be extended except that
the  holder  of a Stock  Option  who  continues  in the  service  of  HUBCO or a
subsidiary of HUBCO will not be deemed to have  terminated  service for purposes
of determining  the Continuing  Stock Option exercise  period).  Shares of HUBCO
Common Stock issuable upon exercise of Continuing  Stock Options will be covered
by an effective  registration statement on Form S-8, and HUBCO has agreed to use
its  reasonable  best  efforts  to file a  registration  statement  on Form  S-8
covering such shares as soon as possible after the Effective Time.

Stock Option to HUBCO for IBSF Shares

         HUBCO and IBSF entered into a Stock Option  Agreement dated as of March
31, 1998 (the "Stock Option  Agreement") in connection  with the  negotiation by
HUBCO and IBSF of the Merger Agreement.  Pursuant to the Stock Option Agreement,
IBSF has  granted  to HUBCO an option  (the  "Option"),  exercisable  only under
certain  limited  and  specifically  defined  circumstances  (none of which  has
occurred as of the date  hereof),  to purchase up to  2,700,000  authorized  but
unissued shares of IBSF Common Stock,  representing  approximately  19.8% of the
shares of IBSF Common  Stock that would be  outstanding  if the Option was fully
exercised,  for an exercise  price of $18.00 per share.  HUBCO does not have any
voting  rights with  respect to the shares of IBSF Common  Stock  subject to the
Option  prior to  exercise  of the Option.  Acquisitions  of IBSF  Common  Stock
pursuant to exercise of the option would be subject to prior regulatory approval
under certain circumstances.

         The Stock  Option  Agreement  is  attached to this Proxy  Statement  as
Appendix B hereto. If certain specifically  enumerated "Triggering Events" occur
and the Merger is not  consummated,  HUBCO would recognize a gain on the sale of
the shares of IBSF Common Stock received  pursuant to the exercise of the Option
if such shares of IBSF  Common  Stock were sold at prices  exceeding  $18.00 per
share.  The  ability  of  HUBCO to  exercise  the  Option  and to cause up to an
additional  2,700,000 shares of IBSF Common Stock to be issued may be considered
a deterrent to other  potential  acquisitions  of control of IBSF,  even if such
potential acquiror were prepared to pay a higher price per share for IBSF Common
Stock,  as it is likely to  increase  the cost of an  acquisition  of all of the
shares of IBSF Common Stock which would then be outstanding. The exercise of the
option  by  HUBCO  may  also  make  pooling-of-interests   accounting  treatment
unavailable to a subsequent acquiror.

         The Option is  exercisable  only upon the  occurrence  of a  Triggering
Event. As used in the Stock Option Agreement,  the term "Triggering Event" means
the occurrence of any of the following events:

         A person or group (as such terms are  defined in the  Exchange  Act and
the rules and regulations thereunder) other than HUBCO or an affiliate of HUBCO:

         a. acquires  beneficial  ownership (as such term is defined in Exchange
Act Rule  13d-3) of at least 15% of the then  outstanding  shares of IBSF Common
Stock; or

         b.  enters  into a letter of intent or an  agreement,  whether  oral or
written, with IBSF pursuant to which such person or any affiliate of such person
would (i) merge or  consolidate,  or enter into any  similar  transaction,  with
IBSF, (ii) acquire all or a significant  portion of the assets or liabilities of
IBSF, or (iii) acquire beneficial ownership of securities  representing,  or the
right to acquire beneficial ownership or to vote securities representing, 15% or
more of the then outstanding shares of IBSF Common Stock; or

         c. makes a filing with any bank or thrift  regulatory  authorities with
respect to or publicly announces a bona fide proposal (a "Proposal") for (i) any
merger with,  consolidation with or acquisition of all or a significant  portion
of all the assets or  liabilities  of,  IBSF or any other  business  combination
involving  IBSF,  or (ii) a  transaction  involving  the transfer of  beneficial
ownership  of  securities  representing,  or the  right  to  acquire  beneficial
ownership or to vote  securities  representing,  15% or more of the  outstanding
shares of IBSF Common  Stock,  and  thereafter,  if such  Proposal  has not been
Publicly  Withdrawn  (as such term is defined in the Stock Option  Agreement) at
least 15 days prior to the meeting of shareholders of IBSF called to vote on the
Merger and IBSF's  shareholders  fail to approve the Merger by the vote required
by applicable law at the meeting of shareholders called for such purpose; or

         d. makes a bona fide Proposal and thereafter,  but before such Proposal
has been Publicly Withdrawn, IBSF willfully takes any action in any manner which
would  materially  interfere  with its  ability  to  consummate  the  Merger  or
materially reduce the value of the transaction to HUBCO.

         The term  "Triggering  Event"  also  means the  taking of any  material
direct or  indirect  action by IBSF or any of its  directors,  senior  executive
officers,  investment  bankers or other person with actual or apparent authority
to speak for the IBSF Board of Directors,  inviting,  encouraging  or soliciting
any  proposal  (other than from HUBCO or an affiliate of HUBCO) which has as its
purpose  a  tender  offer  for  the  shares  of IBSF  Common  Stock,  a  merger,
consolidation,  plan of exchange, plan of acquisition or reorganization of IBSF,
or a sale of a  significant  number  of  shares  of  IBSF  Common  Stock  or any
significant portion of its assets or liabilities.

         The Stock Option  Agreement will terminate upon either the  termination
of  the  Merger  Agreement  as  provided  therein  or  the  consummation  of the
transactions  contemplated by the Merger Agreement;  provided,  however, that if
termination of the Merger  Agreement occurs after the occurrence of a Triggering
Event,  the Stock  Option  Agreement  will not  terminate  until the later of 18
months  following  the date of the  termination  of the Merger  Agreement or the
consummation of any proposed transactions which constitute the Triggering Event.

Background of the Merger

         During the fall of 1997,  the Board of  Directors  of IBSF  interviewed
several  investment  banking  firms to assist the Board in  connection  with its
evaluation of various strategic options to maximize shareholder value, including
a possible  sale of IBSF.  In  October  1997,  IBSF  engaged  Ryan,  Beck as its
financial advisor to conduct a due diligence review of IBSF,  identity potential
acquirors,  assist in the preparation of a confidential offering memorandum, and
assist in any discussions and negotiations with potential acquirors.

         Ryan,  Beck  contacted  29  financial  institutions  or  their  holding
companies  to  determine  their  initial  interest in IBSF.  Beginning  in early
December 1997, a confidential  offering memorandum containing September 30, 1997
data was sent to 23 of these  companies  after they  executed a  confidentiality
agreement.  The companies were initially instructed to provide their preliminary
indications of interest to Ryan, Beck by January 5, 1998, which was subsequently
extended to January 15, 1998 to provide the companies  sufficient time to review
the information package regarding IBSF.

         Four companies provided preliminary indications of interest, which were
presented to the Board of  Directors  of IBSF on February 6, 1998.  Three of the
proposals contemplated a stock for stock exchange and one was for cash only. The
Board  questioned  Ryan,  Beck about the  financial  aspects  of the  proposals,
specifically   inquiring  into  the  key  financial   components  of  comparable
transactions.  The  indications  of  interest by two of the  companies  were not
deemed to be competitive on price. The Board of Directors was also not satisfied
with the two highest  indications of interest,  but it agreed to allow these two
companies to conduct a more  detailed due  diligence  review of IBSF since their
preliminary  indications were within a range of what Ryan, Beck considered to be
fair.

         The  remaining  two  prospective  acquirors  conducted a due  diligence
review of IBSF in February 1998 and then submitted revised proposals, which were
reviewed by the Board of Directors of IBSF on March 20, 1998 with the assistance
of Ryan,  Beck. The Board of Directors was not satisfied  with either  proposal.
Since  HUBCO's  proposal  was the  higher  of the two,  the Board  authorized  a
committee of the Board to meet with Ryan, Beck and HUBCO to further negotiate on
price.

         A meeting with the Chief  Executive  Officer of HUBCO was held on March
23, 1998. After further  discussions the proposed  exchange ratio was increased.
The  Board of  Directors  of IBSF met  again on March  25,  1998 and  authorized
management  and IBSF's  representatives  to negotiate  the terms of a definitive
agreement.

         The  management  of IBSF  reviewed  and revised  several  drafts of the
definitive  agreement with the assistance of IBSF's legal counsel and investment
banker, and a draft of the definitive  agreement was delivered to each of IBSF's
directors for their review on March 30, 1998.

         On March 31, 1998, the Board of Directors of IBSF reviewed the proposed
definitive  Merger Agreement with IBSF's legal counsel and Ryan, Beck. The Board
of Directors  considered  all factors  deemed  relevant,  including  information
regarding HUBCO's other then pending  acquisitions and Ryan, Beck's opinion that
the  Exchange  Ratio is fair to IBSF's  shareholders  from a financial  point of
view. The Board of Directors  determined that the proposed Merger is in the best
interests of IBSF and its shareholders,  and the Board unanimously  approved the
Merger. HUBCO and IBSF publicly announced the Merger on March 31, 1998.

IBSF Board's Reasons for the Merger and Recommendation

         The terms of the Merger Agreement, including the Exchange Ratio and the
value of the HUBCO Common Stock to be received by IBSF's shareholders,  were the
result of  arm's-length  negotiations  between the  representatives  of IBSF and
HUBCO.  Among  the  factors  considered  by the  Board of  Directors  of IBSF in
deciding to approve and  recommend the terms of the Merger were (i) the value of
the  HUBCO  Common  Stock to be  received  by IBSF's  shareholders  based on the
Exchange Ratio in relation to the market value,  book value,  earnings per share
and dividend  rates of the IBSF Common Stock,  (ii)  information  concerning the
financial  condition,  results of operations,  capital levels, asset quality and
prospects of IBSF,  (iii) industry and economic  conditions,  (iv) the impact of
the Merger on the depositors,  employees,  customers and  communities  served by
IBSF  through  expanded  commercial,  consumer and retail  banking  products and
services,  (v) the opinion of IBSF's financial advisor as to the fairness of the
Exchange Ratio from a financial  point of view to the holders of the IBSF Common
Stock,  (vi) the general  structure of the transaction and the  compatibility of
management  and business  philosophy,  (vii) the  likelihood  of  receiving  the
requisite regulatory approvals in a timely manner, and (viii) the ability of the
combined  enterprise to compete in relevant banking and non-banking  markets. In
making  its  determination,  the  Board of  Directors  of IBSF  did not  ascribe
relative weights to the factors which it considered.

         The Board of Directors of IBSF  believes that the Merger is in the best
interest  of IBSF  and its  shareholders.  THE  BOARD OF  DIRECTORS  UNANIMOUSLY
RECOMMENDS THAT THE SHAREHOLDERS VOTE FOR THE APPROVAL OF THE MERGER AGREEMENT.

HUBCO's Reasons for the Merger

         HUBCO  entered into the Merger  Agreement  with IBSF as part of HUBCO's
ongoing strategy of growth through acquisitions.

         HUBCO's   acquisition   strategy  consists  of  identifying   financial
institutions  with  business  philosophies  that are similar to  HUBCO's,  which
operate in markets  that are  geographically  within or close to those of HUBCO,
and which  provide an ability to enhance  earnings per share over an  acceptable
period  after the  acquisition,  while  providing  acceptable  rates of  return.
Acquisitions  are also evaluated in terms of asset quality,  interest rate risk,
core deposit base stability,  potential  operating  efficiencies  and management
abilities.

         Pursuant to this acquisition  strategy,  HUBCO has pursued acquisitions
of  financial  institutions  in  New  Jersey  and  in  other  states  which  are
geographically close to HUBCO's current markets and which otherwise meet HUBCO's
acquisition goals.  HUBCO's  expressions of interest in and merger with IBSF are
consistent with this strategy.  HUBCO  anticipates that combining the New Jersey
operations of the  Association  and HUB will enhance  HUBCO's ability to promote
operational  efficiencies and services to the combined  institutions' New Jersey
customers.

Opinion of IBSF's Financial Advisor

         On October 7, 1997, IBSF formally  retained Ryan, Beck to act as IBSF's
financial  advisor  with  respect  to the  acquisition  of IBSF.  Ryan,  Beck is
regularly engaged in the valuation of banks, bank holding companies, savings and
loan  associations,  savings  banks and savings and loan  holding  companies  in
connection with mergers, acquisitions and other securities-related transactions.
Ryan,  Beck has knowledge of, and  experience  with,  the  Mid-Atlantic  banking
market and banking organizations  operating within this market, and was selected
by IBSF because of its  knowledge of,  experience  with,  and  reputation in the
financial services industry.

   

         In its capacity as IBSF's financial advisor, Ryan, Beck participated in
the  negotiations  with respect to the pricing and other terms and conditions of
the Merger,  but the decision as to whether to accept the HUBCO proposal and the
final  pricing of the Merger was  ultimately  made by the Board of  Directors of
IBSF.  Ryan,  Beck  rendered  its oral opinion to the IBSF Board of Directors on
March 31, 1998,  subsequently  confirmed by a formal written opinion dated as of
the same date, and rendered an additional  formal written  updated opinion dated
July 10,  1998 (the  "Opinion")  that based on and  subject to the  assumptions,
factors,  and limitations set forth in the Opinion and as described  below,  the
Exchange Ratio is fair to IBSF's shareholders from a financial point of view. No
limitations  were  imposed by the IBSF Board of Directors  upon Ryan,  Beck with
respect to the investigations  made or procedures  followed by it in arriving at
its opinion.

         The full text of the Opinion of Ryan,  Beck dated as of July 10,  1998,
which sets  forth  assumptions  made and  matters  considered,  is  attached  as
Appendix C to this Proxy Statement-Prospectus. Shareholders of IBSF are urged to
read this Opinion in its entirety.  Ryan, Beck's Opinion is directed only to the
Exchange Ratio and does not constitute a recommendation  to any IBSF shareholder
as to how such shareholder  should vote at the Special  Meeting.  The summary of
the  Opinion  of Ryan,  Beck set  forth in this  Proxy  Statement-Prospectus  is
qualified in its entirety by reference to the full text of such  Opinion.  Ryan,
Beck's oral and written opinions as of March 31, 1998 were to the same effect as
the Opinion.  In rendering the Opinion  Ryan,  Beck does not admit that it is an
expert within the meaning of the term "expert" as used within the Securities Act
and the rules  and  regulations  promulgated  thereunder,  or that its  opinions
constitute  a report or  valuation  within  the  meaning  of  Section  11 of the
Securities Act and the rules and regulations promulgated thereunder.

         In connection  with its analysis,  Ryan,  Beck: (i) reviewed the Merger
Agreement and related documents; (ii) reviewed this Proxy  Statement-Prospectus;
(iii) reviewed HUBCO's Annual Reports to Shareholders and Annual Reports on Form
10-K for the years ended  December 31, 1997,  1996,  1995,  and 1994 and HUBCO's
Quarterly  Reports on Form 10-Q for the periods ended March 31, 1998,  September
30, 1997, June 30, 1997 and March 31, 1997; (iv) reviewed  HUBCO's  Registration
Statements  on Form S-4,  dated  June 10,  1998,  May 8, 1998,  March 17,  1998,
February  20,  1998,  and November 12, 1997 with respect to HUBCO's then pending
acquisitions  of DFC,  CFHC,  MSB,  PFC,  and TBOS,  respectively;  (v) reviewed
HUBCO's press  releases  dated March 2, 1998 and August 28, 1997 with respect to
HUBCO's then pending acquisitions of the Completed Branch Purchase,  the Pending
Branch  Purchase  and  Security  National  Bank and Trust  Company of New Jersey
("SNB"),  respectively;  (vi)  reviewed  internal  analyses  prepared by HUBCO's
management  containing pro forma  financial  statements and  projections for the
acquisitions  of MSB, PFC,  TBOS,  CFHC, the Branch  Purchase,  SNB and DFC (the
"Acquisitions");  (vii) reviewed  HUBCO's Current Reports on Form 8-K dated July
6, 1998 and July 10, 1998; (viii) reviewed HUBCO's Private Placement  Memorandum
dated June 16, 1998 with respect to the 7.65% Capital Securities issued by HUBCO
Capital Trust II; (ix) reviewed IBSF's Annual Reports to Shareholders and Annual
Reports on Form 10-K for the years ended September 30, 1997, 1996, and 1995, and
IBSF's  Quarterly  Reports on Form 10-Q for the periods  ended  March 31,  1998,
December 31,  1997,  June 30,  1997,  March 31, 1997 and December 31, 1996;  (x)
reviewed the  historical  stock prices and trading volume of HUBCO Common Stock;
(xi)  reviewed  publicly   available   financial  data  of  commercial   banking
organizations  which Ryan,  Beck deemed  generally  comparable  to HUBCO;  (xii)
reviewed publicly available  financial data of thrift  organizations which Ryan,
Beck deemed generally  comparable to IBSF;  (xiii) reviewed the historical stock
prices and trading  volume of IBSF Common Stock;  (xiv) reviewed terms of recent
acquisitions  of  thrift   organizations   which  Ryan,  Beck  deemed  generally
comparable  in whole or in part to IBSF;  (xv)  reviewed the potential pro forma
impact of the Merger on HUBCO's financial  condition,  operating results and per
share figures; and (xvi) conducted such other studies,  analyses,  inquiries and
examinations as Ryan, Beck deemed appropriate.  Ryan, Beck also reviewed certain
projections provided by IBSF and HUBCO for the year ending December 31, 1998 and
met with  certain  members of IBSF's and HUBCO's  senior  management  to discuss
IBSF's and HUBCO's past and current business  operations,  financial  condition,
strategic  plan  and  future  prospects,   including  any  potential   operating
efficiencies and synergies which may arise from the Merger and the Acquisitions.
As part of its review of the Merger, Ryan, Beck also analyzed HUBCO's ability to
consummate the Merger and  considered the future  prospects of IBSF in the event
it remained independent.

    

         In  connection  with its review,  Ryan,  Beck relied upon and  assumed,
without independent verification, the accuracy and completeness of the financial
and other information  regarding IBSF,  HUBCO, and the Acquisitions  provided to
Ryan,  Beck by IBSF and HUBCO and their  representatives.  Ryan,  Beck is not an
expert in the evaluation of allowances for loan losses.  Therefore,  Ryan,  Beck
has not assumed any responsibility  for making an independent  evaluation of the
adequacy of the  allowances  for loan losses set forth in the balance  sheets of
IBSF,  HUBCO and the Acquisitions at March 31, 1998, and Ryan, Beck assumed such
allowances  were adequate and complied  fully with  applicable  law,  regulatory
policy and sound banking  practice as of the date of such financial  statements.
Ryan,  Beck  has  reviewed  certain  historical  financial  data  and  financial
projections,  including the impact of the Acquisitions  (and the assumptions and
bases  therefor),  provided  by IBSF and HUBCO.  Ryan,  Beck  assumed  that such
forecasts and projections  reflected the best currently  available estimates and
judgments of the respective managements.  In certain instances, for the purposes
of its analyses,  Ryan,  Beck made  adjustments  to such financial and operating
forecasts   which  in  Ryan,   Beck's  judgment  were   appropriate   under  the
circumstances.  Ryan,  Beck was not retained to nor did it make any  independent
evaluation or appraisal of the assets or liabilities of IBSF, HUBCO or the other
institutions  subject to the  Acquisitions,  nor did Ryan,  Beck review any loan
files of IBSF, HUBCO, or the other institutions subject to the Acquisitions,  or
their  respective  subsidiaries.  Ryan, Beck also assumed that the Merger in all
respects is, and will be, undertaken and consummated in compliance with all laws
and regulations that are applicable to IBSF and HUBCO.

         The  preparation  of a fairness  opinion on a  transaction  such as the
Merger involves various  determinations  as to the most appropriate and relevant
methods  of  financial  analysis  and the  application  of those  methods to the
particular  circumstances and, therefore, the Opinion is not readily susceptible
to summary  description.  In arriving at its  opinion,  Ryan,  Beck  performed a
variety of financial  analyses.  Ryan,  Beck  believes that its analyses must be
considered as a whole and the consideration of portions of such analyses and the
factors considered therein,  without considering all factors and analyses, could
create an  incomplete  view of the  analyses  and the process  underlying  Ryan,
Beck's Opinion. No one of the analyses was assigned a greater  significance than
any other.

         The projections furnished to Ryan, Beck were prepared by the respective
managements of IBSF and HUBCO.  IBSF and HUBCO do not publicly disclose internal
management projections of the type provided to Ryan, Beck in connection with the
review of the Merger.  Such  projections  were not prepared  with a view towards
public disclosure. The public disclosure of such projections could be misleading
since the projections were based on numerous variables and assumptions which are
inherently uncertain,  including, without limitation, factors related to general
economic and  competitive  conditions.  Accordingly,  actual  results could vary
significantly from those set forth in such projections.

         In its analyses,  Ryan, Beck made numerous  assumptions with respect to
industry performance,  business and economic conditions, and other matters, many
of which are beyond the control of IBSF or HUBCO.  Any  estimates  contained  in
Ryan,  Beck's  analyses  are not  necessarily  indicative  of future  results or
values,  which may be significantly  more or less favorable than such estimates.
Estimates  of values of companies  do not purport to be  appraisals  nor do they
necessarily  reflect  the  prices at which  companies  or their  securities  may
actually be sold.

The  following is a brief  summary of the analyses and  procedures  performed by
Ryan, Beck in the course of arriving at its Opinion.

         Analysis of Selected  Publicly  Traded  Companies:  Ryan, Beck compared
IBSF's  financial  data as of  December  31, 1997 to a peer group of 17 selected
thrifts located in the New England and Mid-Atlantic  Regions with assets between
$500  million and $1  billion.  Ryan,  Beck  deemed  this group to be  generally
comparable to IBSF. At or for the twelve  months ended  December 31, 1997,  IBSF
had equity to assets of 17.74%, a return on average assets of 0.79%, a return on
average equity of 4.36%,  a dividend  yield of 2.00%,  a net interest  margin of
3.12%,  loans  equal to 29.98% of assets,  a ratio of  non-performing  assets to
total assets of 0.11%, a ratio of loan loss reserves to non-performing  loans of
130.18%,  a ratio of  non-interest  expenses to average assets of 1.93%,  and an
efficiency  ratio of 61.58%.  These ratios were compared to the median ratios of
the 17 selected thrift  organizations,  which were, as calculated,  an equity to
assets ratio of 8.27%,  a return on average assets of 0.94%, a return on average
equity of 10.51%,  a dividend  yield of 1.70%,  a net interest  margin of 3.32%,
loans  equal to  50.69% of  assets,  a ratio of  non-performing  assets to total
assets  of 0.33%,  a ratio of loan  loss  reserves  to  non-performing  loans of
131.79%,  a ratio of  non-interest  expense to average  assets of 2.15%,  and an
efficiency ratio of 58.09%. Ryan, Beck noted that IBSF's performance as measured
by return on average equity was weaker than that of the peer group,  largely due
to the fact that IBSF had a much higher  level of equity as compared to the peer
group. Ryan, Beck noted that IBSF's performance as measured by return on average
assets was weaker than that of the peer group, largely due to the lower level of
loans at IBSF as compared to the peer group.  Ryan,  Beck also noted that IBSF's
non-interest  expenses as a percent of average assets was lower than that of the
peer group.  However,  IBSF's efficiency ratio was slightly higher than the peer
group because IBSF's revenue is lower than that of its peers.

         Ryan, Beck also compared HUBCO's reported financial data as of December
31, 1997 with that of a group of 20 selected  commercial  banking  organizations
with assets  between $2 billion and $15 billion and which are located in the New
England and  Mid-Atlantic  regions of the United States for which public trading
and  pricing  information  was  available.  Ryan,  Beck  deemed this group to be
generally  comparable to HUBCO. HUBCO data was presented as reported at December
31, 1997 with certain data pro forma for the  Acquisitions  and IBSF. Ryan, Beck
noted that HUBCO  reported  total  assets of $3 billion at December 31, 1997 and
assets pro forma for the  Acquisitions  and IBSF at December 31, 1997 would have
been $7 billion.  At or for the twelve months ended December 31, 1997, HUBCO had
a ratio of equity to assets of 6.11% (7.34% pro forma for the  Acquisitions  and
IBSF),  a return  on  average  assets  ratio of 1.66%  (1.30%  pro forma for the
Acquisitions  and  IBSF,   including   expense  savings   estimated  by  HUBCO's
management),  a return on average  equity ratio of 24.36%  (17.57% pro forma for
the  Acquisitions  and IBSF,  including  expense  savings  estimated  by HUBCO's
management),  a dividend yield of 2.05%, a net interest margin of 5.20%, a ratio
of  non-performing  assets  to total  assets of 1.23%  (1.13%  pro forma for the
Acquisitions  and IBSF),  and a ratio of loan loss  reserves  to  non-performing
loans (excluding loans 90 days past due and still accruing  interest) of 108.91%
(97.29% pro forma for the Acquisitions and IBSF).  These ratios were compared to
the median ratios of the 20 selected  commercial  banking  organizations,  which
were,  as  calculated,  an equity to assets ratio of 8.46%,  a return on average
assets ratio of 1.25%,  a return on average  equity ratio of 14.95%,  a dividend
yield of 1.92%, a net interest margin of 4.55%, a ratio of non-performing assets
to total  assets of 0.42% and a ratio of loan loss  reserves  to  non-performing
loans (excluding loans 90 days past due and still accruing interest) of 243.06%.
Using HUBCO's  common stock price as  represented by the last trade on March 27,
1998,  its price to 1998  estimated  earnings  per share was 16.71 times  (16.57
times pro forma for the Acquisitions),  price to book value was 458.63% (303.26%
pro forma for the  Acquisitions),  and price to tangible  book value was 527.62%
(370.84% pro forma for the Acquisitions).  The peer group's median price to 1998
earnings was 19.01 times,  price to book value was 287.86% and price to tangible
book value was 295.50%.

         Analysis of Selected Transactions: Ryan, Beck compared IBSF's financial
data  as of  December  31,  1997  with  that of a group  of 36  selected  thrift
organizations being acquired in transactions announced since January 1, 1997 and
for which pricing data pertaining to the  transactions  was publicly  available.
The  criteria   for  this  group  was  thrifts   located  in  the  New  England,
Mid-Atlantic,  Midwest,  Southwest,  and  Southeast  regions of the country with
assets  greater than $200 million and an equity to assets ratio greater than 8%.
Ryan,  Beck deemed this group to be  generally  comparable  to IBSF.  The median
ratios of the 36 selected companies, as calculated, represented a 9.08% tangible
equity to tangible  assets  ratio,  a  non-performing  assets to assets ratio of
0.32%,  an  annualized  year-to-date  return on  average  assets of 0.99% and an
annualized year-to-date return on average equity of 9.91%.

   

         Ryan, Beck also  calculated  certain ratios based on the Exchange Ratio
of 0.534  shares of HUBCO  Common  Stock for each  share of IBSF  Common  Stock,
HUBCO's  closing stock price on March 30, 1998, and the median ratios for the 36
selected thrift acquisitions ("Comparable Transactions").  The price represented
175.64% of stated  book value at December  31,  1997,  175.64% of tangible  book
value at December  31,  1997,  323.53% of core book value at December  31, 1997,
38.38 times  latest  twelve  months  diluted  earnings,  22.78 times  normalized
earnings,  a deposit premium on core capital of 33.04% at December 31, 1997, and
a core deposit  premium over tangible book value at December 31, 1997 of 17.62%.
Core capital was defined to equal 6% of assets (i.e. a capital level  sufficient
to support  IBSF's asset base under its current  operating  strategy);  and core
book value equaled core capital  divided by outstanding  common  shares.  It was
also assumed for  calculations  involving  core capital and core book value that
excess capital was returned dollar for dollar to IBSF  shareholders.  Normalized
earnings adds back certain expenses such as the MRP, ESOP,  Excess Benefit Plan,
and additional expenses associated with IBSF's proxy contest to IBSF's estimated
1998  net  income.  The  median  ratios  for  the  Comparable  Transactions,  as
calculated,  represented  a price to stated  book value of  202.71%,  a price to
tangible book value of 204.82%,  a price to core book value of 293.62%,  a price
to latest twelve months diluted  earnings of 20.18 times, a deposit premium over
core capital of 24.78 times, and a core deposit premium over tangible book value
of 19.06%.  The  imputed  value of IBSF based on the median  ratios of the above
mentioned acquisition peer group was $23.92 based on price to stated book value,
$24.17 based on price to tangible  book value,  $19.53 based on core book value,
$10.90 based on latest twelve months diluted earnings,  $18.36 based on the peer
group's  multiple  of  latest  twelve  months  earnings  and  IBSF's  normalized
earnings,  $16.54 based on a deposit premium over core capital, and $21.64 based
on the core deposit premium over tangible book value.  Ryan, Beck considered the
core book value ratios to be much more  relevant  since IBSF's  equity to assets
ratio at 17.74% was more than twice that of the peer group median at 8.27%.

    

         No company or  transaction  used in the  Analysis of Selected  Publicly
Traded Companies and Analysis of Selected  Transactions sections is identical to
IBSF,  HUBCO or the  Merger.  Accordingly,  an  analysis  of the  results of the
foregoing is not  mathematical;  rather it involves complex  considerations  and
judgments concerning  differences in financial and operating  characteristics of
the companies involved and other factors that could affect the trading values of
the securities of the company or companies to which they are being compared.

         Impact Analysis:  Ryan, Beck analyzed the Merger in terms of its effect
on HUBCO's (pro forma for the Acquisitions) projected 1998 and 1999 earnings per
share,  stated book value and tangible book value based on IBSF's projected 1998
and  1999  earnings  which  were  derived  from  information   provided  by  the
managements of IBSF and HUBCO. Based upon certain  assumptions,  including those
with  respect  to cost  savings  and other  synergies  from the  Merger  and the
stand-alone earnings projections provided by HUBCO and IBSF, the analysis showed
that the  Merger  would be  accretive  to HUBCO's  projected  1998  fiscal  year
earnings per share by  approximately  0.33%,  dilutive to projected  1999 fiscal
year  earnings  per share by  approximately  0.41%,  accretive to book value per
share by  approximately  13.65% and accretive to HUBCO's  tangible book value by
approximately  23.02%.  Ryan,  Beck  analyzed  the impact of the Merger on HUBCO
values  per IBSF  share  based on the  Exchange  Ratio of 0.534  shares of HUBCO
Common Stock for each share of IBSF Common Stock using pro forma  projected 1998
fiscal year earnings per share,  pro forma  projected  1999 fiscal year earnings
per share,  pro forma stated book value per share, pro forma tangible book value
per share and  dividends  per share at December 31, 1997.  That  analysis  found
that, based on such Exchange Ratio,  IBSF's  equivalent  projected 1998 earnings
per share would increase by approximately  120.64%,  projected 1999 earnings per
share would increase by approximately 117.89%,  stated book value would decrease
by approximately  41.89% and tangible book value would decrease by approximately
52.61%.  Additionally,  IBSF  shareholders,  based on HUBCO's  current  dividend
level, would receive annual dividends of $0.43 per share as compared to $0.40 at
the  present  time.  The actual  results  achieved  may vary from the  projected
results and the variations may be material.

         Discounted  Dividend  Analysis:  Using a discounted  dividend analysis,
Ryan, Beck estimated the present value of the future dividend  streams that IBSF
could produce in  perpetuity.  Projection  ranges for IBSF's  five-year  balance
sheet and income  statement  were  provided by IBSF's  management.  Management's
projections were based upon various factors and  assumptions,  many of which are
beyond  the  control  of  IBSF.   These   projections   are,  by  their  nature,
forward-looking  and may  differ  materially  from the  actual  values or actual
future results which may be significantly  more or less favorable than suggested
by such projections.  In producing a range of per share IBSF values,  Ryan, Beck
utilized the following  assumptions:  discount  rates range from 10.0% to 14.0%,
terminal  price/earnings  multiples  ranging  from  13.0x to 15.0x  (which  when
applied to terminal year estimated  earnings produces a value which approximates
the net present value of the dividends in perpetuity,  given certain assumptions
regarding  growth rates and discount rates) and earnings that include  estimated
savings in IBSF's  non-interest  expense equal to 71% in 1998 and 1999,  with an
assumed 5% growth in  synergies in years  thereafter.  The  discounted  dividend
analysis  produced a range of net present  values per share of IBSF Common Stock
from $17.52 to $20.94.  These analyses do not purport to be indicative of actual
values or  expected  values or an  appraisal  range of the shares of IBSF Common
Stock.  Ryan, Beck noted that the discounted  dividend analysis is a widely used
valuation  methodology,  but  noted  that it  relies  on  numerous  assumptions,
including  expense  savings levels,  dividend payout rates,  terminal values and
discount  rates,  the future values of which may be  significantly  more or less
than such alternatives.

   

         In connection with its written Opinion dated as of July 10, 1998, Ryan,
Beck  confirmed  the  appropriateness  of its reliance on the  analyses  used to
render its March 31, 1998 written  opinion by  performing  procedures  to update
certain of such  analyses  and by  reviewing  the  assumptions  and  conclusions
contained in the Opinion.

         Ryan,  Beck's written Opinion dated July 10, 1998 was based solely upon
the information available to it and the economic, market and other circumstances
as they existed as of the date of such Opinion.  Ryan,  Beck did not express any
opinion as to the price or range of prices at which  HUBCO  Common  Stock  might
trade  subsequent  to  the  Merger.  Events  occurring  after  such  date  could
materially  affect the assumptions  and  conclusions  contained in such Opinion.
Ryan,  Beck has not  undertaken  to reaffirm or revise its Opinion or  otherwise
comment upon any events occurring after the date thereof.

    

         The  summary  set  forth  above  does  not  purport  to  be a  complete
description,  but is a brief  summary of the material  analyses  and  procedures
performed by Ryan, Beck in the course of arriving at its Opinion.

         With regard to Ryan,  Beck's  services in connection with the financial
advisory  agreement and the Merger Agreement,  IBSF has agreed to pay Ryan, Beck
an  advisory  fee  equal  to  0.85%  of  the  aggregate   dollar  value  of  the
consideration  received by IBSF's  shareholders  in the  Merger.  Based upon the
estimated  aggregate  purchase  price to be paid in connection  with the Merger,
Ryan,  Beck's aggregate fees will be  approximately  $2 million.  Ryan, Beck was
paid  approximately  $505,000 of its advisory fee upon the delivery of the March
31, 1998 written  opinion and the remainder will be paid upon the closing of the
Merger. In addition,  IBSF has agreed to reimburse Ryan, Beck for its reasonable
out-of-pocket expenses, which shall not exceed $10,000 without the prior consent
of IBSF.  IBSF has also  agreed to  indemnify  Ryan,  Beck and  certain  related
persons  against  certain  liabilities,   including  liabilities  under  federal
securities law,  incurred in connection with its services.  The amounts of Ryan,
Beck's fees were determined by negotiation between IBSF and Ryan, Beck.

         Ryan, Beck has had an investment  banking  relationship with IBSF for a
number of years.  Ryan, Beck was the sole underwriter of IBSF's  conversion from
mutual to stock form of organization. Additionally, Ryan, Beck has also acted as
financial  advisor to IBSF with  respect to various  other  matters from time to
time. Ryan,  Beck's research  department has issued research reports on IBSF and
comments on IBSF in its periodic commentaries. Ryan, Beck is also a market maker
in IBSF's  common  stock and, in such  capacity,  may from time to time own IBSF
securities.

         Ryan, Beck was a co-manager of the 8.98% Capital Securities offering by
HUBCO Capital Trust I. Ryan,  Beck's  research  department  has issued  research
reports on HUBCO and comments on HUBCO in its periodic commentaries.  Ryan, Beck
is also a market  maker in HUBCO Common  Stock and, in such  capacity,  may from
time to time own HUBCO securities.

liabilities not in the ordinary course of business or similar  transactions  (an
"Acquisition  Transaction").  Notwithstanding the foregoing, IBSF may enter into
discussions or  negotiations  or provide any  information in connection  with an
unsolicited possible Acquisition  Transaction if the Board of Directors of IBSF,
after  consulting  with  counsel,  determines  in the exercise of its  fiduciary
responsibilities  that such  discussions or negotiations  should be commenced or
such information should be furnished. IBSF has agreed to promptly communicate to
HUBCO the terms of any proposal,  whether written or oral,  which it may receive

Regulatory Approvals

   

         Consummation  of the Merger is subject,  among other  things,  to prior
receipt of all necessary regulatory approvals. In order to consummate the Merger
and the Bank Merger,  HUBCO must obtain  regulatory  approvals from the FDIC and
the NJDOB and an approval or waiver from the FRB. HUBCO has received a waiver of
approval  from the FRB.  HUBCO has applied to the FDIC for approval to merge the
Association  into  HUB,  and  has  applied  to the  NJDOB  for  approval  of the
acquisition of the Association.  Approval by the FRB, FDIC or the NJDOB does not
constitute an  endorsement  of the Merger or the Bank Merger or a  determination
that the terms of the Merger or Bank Merger are fair to the shareholders of IBSF
or HUBCO.

    

Interests of Certain Persons in the Merger

         The Merger  Agreement  provides that HUBCO will cause Joseph M. Ochman,
Sr.,  the  Chairman,  President  and  Chief  Executive  Officer  of IBSF,  to be
appointed as a director of the  Surviving  Bank and Chairman of the Southern New
Jersey  Advisory  Council  of the  Surviving  Bank at the  Closing.  The  Merger
Agreement  also provides that Mr. Ochman will receive a consulting  contract for
services  to be rendered  through  April 30, 2001 (the  "Consulting  Term"),  in
exchange for a fee payable monthly at the rate of $150,000 per annum. During the
Consulting Term, (1) Mr. Ochman will be provided with a secretary and the use of
an office,  (2) HUBCO or a HUBCO  subsidiary will pay the insurance  premiums on
the life  insurance  policies on Mr.  Ochman's life,  which  premiums  aggregate
$9,510 per year, and (3) HUBCO or a HUBCO  subsidiary  will pay or reimburse Mr.
Ochman for various legal, tax and estate planning services, as well as an annual
medical  exam,  in an  aggregate  amount of up to $7,500  per year.  The  Merger
Agreement  also  provides that HUBCO will cause Mr. Ochman to be re-elected as a
director  of the  Surviving  Bank and as  Chairman  of the  Southern  New Jersey
Advisory  Council  so that  his  terms  continue  until  the  year  2001  annual
stockholder meeting of the Surviving Bank.

   

         HUBCO  also  agreed  to  honor  the  existing  written  employment  and
severance agreements with officers and employees of IBSF and the Association and
Mr. Ochman's Excess Benefit Plan. Under his employment  agreements with IBSF and
the  Association,   Mr.  Ochman  will  receive  a  lump  sum  severance  payment
aggregating  approximately $1.7 million, together with the continuation of a car
allowance, life insurance,  long-term disability insurance and club dues through
the remaining term of his contracts and health insurance until age 70.

    

         All  unvested  stock  options and  restricted  stock awards held by the
directors,  officers and employees of IBSF and the  Association  (including  Mr.
Ochman)  will  accelerate  and become fully vested as the  Effective  Time.  For
information  regarding the amount of unvested stock options and restricted stock
awards, see "Security  Ownership of Certain  Beneficial  Officers of IBSF Common
Stock." The stock options will be converted into stock options to purchase HUBCO
Common  Stock as set  forth  under " -  Conversion  of Stock  Options,"  and the
holders of the restricted stock awards that accelerate will receive HUBCO Common
Stock based upon the Exchange Ratio. In addition,  certain employees  (including
two executive officers other than Mr. Ochman) will receive  "retention"  bonuses
from IBSF or the  Association  in the event the employee  remains an employee of
IBSF or the  Association  through the Effective Time (or the subsequent  systems
conversion in certain cases). The retention bonuses will not exceed an aggregate
of $150,000.

         In the Merger Agreement, HUBCO has agreed to indemnify, defend and hold
harmless for a period of six years after the Effective Time, each person who is,
has been, or becomes prior to the Effective Time, a director,  officer, employee
or agent of IBSF,  or who  serves or has  served at the  request  of IBSF in any
capacity with any other entity (collectively, the "Indemnitees"), to the fullest
extent  which IBSF would have been  permitted  under  applicable  law and IBSF's
Certificate  of  Incorporation  and Bylaws had the  Merger  not  occurred,  with
respect to any claims made  against  such  person  because he or she is or was a
director,  officer,  employee  or agent of IBSF or serves  or has  served at the
request of IBSF in any capacity with any other entity.  In the Merger Agreement,
HUBCO has also agreed to cover  IBSF's  officers and  directors  under either an
extension of IBSF's existing directors' and officers' liability insurance policy
or a rider to HUBCO's  then  current  policy for a period of six years after the
Effective Time.

         The Merger  Agreement  provides  that  IBSF's  (and the  Association's)
directors  and  officers  have "third party  beneficiary  rights" to enforce the
provisions of the Merger Agreement  relating to  indemnification of such persons
following  the Merger.  No "third party  beneficiary  rights" are granted in the
Merger  Agreement  to enforce any other  agreements  made by HUBCO in the Merger
Agreement with respect to employee benefits or other post-closing matters.

Management and Operations After the Merger

         At the Effective  Time, as a result of the Merger,  IBSF will be merged
with and into HUBCO, with HUBCO as the Surviving Entity.  Immediately  following
the Effective Time, the  Association  will be merged with and into HUB, with HUB
as the Surviving Bank.

         The Merger  Agreement  provides that HUBCO will cause Joseph M. Ochman,
Sr. to be  appointed  as a director of the  Surviving  Bank and  Chairman of the
Southern New Jersey Advisory Council of the Surviving Bank.

Exchange of Certificates, Issuance of New Options

         At the Effective Time,  holders of certificates  formerly  representing
shares of IBSF Common  Stock will cease to have any rights as IBSF  shareholders
and their  certificates  automatically will represent the shares of HUBCO Common
Stock into which their shares of IBSF Common  Stock will have been  converted by
the Merger.  Promptly after the Effective  Time, but in no event later than five
business days after the Effective Time, HUBCO will send written instructions and
a letter of  transmittal  to each holder of IBSF Common  Stock,  indicating  the
method for exchanging their stock  certificates  for  certificates  representing
shares of HUBCO  Common  Stock.  Holders of IBSF Common Stock should not send in
their stock certificates until they receive instructions from HUBCO.

         Each share of HUBCO  Common Stock for which shares of IBSF Common Stock
are  exchanged  will be  deemed  to have  been  issued  at the  Effective  Time.
Accordingly,  holders of IBSF Common Stock who receive HUBCO Common Stock in the
Merger will be entitled to receive any dividend or other  distribution which may
be payable to  holders  of record of such HUBCO  Common  Stock as of dates on or
after the  Effective  Time.  However,  no  dividend or other  distribution  will
actually  be paid with  respect to any shares of HUBCO  Common  Stock  until the
certificate or certificates  formerly  representing  shares of IBSF Common Stock
have  been   surrendered,   at  which  time  any  accrued  dividends  and  other
distributions  on such  shares  of  HUBCO  Common  Stock  will  be paid  without
interest. See "-- Consideration".

         Holders of outstanding  certificates for IBSF Common Stock, upon proper
surrender  of such  certificates  to HUBCO,  will  receive,  promptly  after the
Effective  Time, a certificate  representing  the full number of shares of HUBCO
Common Stock into which the shares of IBSF Common Stock  previously  represented
by the surrendered  certificates have been converted. At the time of issuance of
the new stock certificate, each shareholder so entitled will receive a check for
the amount of the fractional  share  interest,  if any, to which the shareholder
may be entitled.

         Following the Effective Time,  HUBCO will make  arrangements  with each
holder of a  Continuing  Stock Option to exchange  the  Optionee's  Option Grant
Agreement for an agreement  reflecting the  conversion of the  Continuing  Stock
Option into an option to acquire HUBCO Common Stock.

Resale Considerations With Respect to the HUBCO Common Stock

         The shares of HUBCO  Common  Stock that will be issued if the Merger is
consummated  have been  registered  under the  Securities Act and will be freely
transferable,  except for shares  received by persons,  including  directors and
executive  officers of IBSF, who may be deemed to be  "affiliates" of IBSF under
Rule 145  promulgated  under the Securities  Act. An "affiliate" of an issuer is
defined  generally as a person who "controls" the issuer.  Directors,  executive
officers and 10%  shareholders  may be deemed to control the issuer.  Affiliates
may not sell their shares of HUBCO Common Stock acquired pursuant to the Merger,
except pursuant to an effective  registration statement under the Securities Act
covering  the HUBCO  Common  Stock or in  compliance  with  Rule 145 or  another
applicable exemption from the registration requirements of the Securities Act.

         Persons  who may be deemed to be  "affiliates"  of IBSF have  delivered
letters to HUBCO in which  they have  agreed to  certain  restrictions  on their
ability to sell,  transfer or otherwise  dispose of ("transfer") any IBSF Common
Stock owned by them and any HUBCO Common  Stock  acquired by them in the Merger.
Pursuant to the accounting rules governing a pooling-of-interests,  such persons
have agreed not to transfer the shares during the period beginning 30 days prior
to the Effective Time and ending on the date on which financial results covering
at least 30 days of post-merger  combined operations of HUBCO and IBSF have been
published or filed by HUBCO.  Also, in connection with the  pooling-of-interests
rules,  such persons have agreed not to transfer  their IBSF Common Stock in the
period prior to 30 days before the Effective  Time without  giving HUBCO advance
notice  and an  opportunity  to  object if the  transfer  would  interfere  with
pooling-of-interests  accounting  for the  Merger.  Pursuant  to Rule 145,  such
persons  have also  agreed to  refrain  from  transferring  HUBCO  Common  Stock
acquired by them in the Merger,  except in compliance with certain  restrictions
imposed by Rule 145. Certificates  representing the shares of HUBCO Common Stock
acquired  by  each  such  person  pursuant  to the  Merger  will  bear a  legend
reflecting  that the shares are restricted in accordance  with the letter signed
by such  person  and may not be  transferred  except  in  compliance  with  such
restrictions.

         Persons  who may be deemed  "affiliates"  of HUBCO have also  delivered
letters to HUBCO in which they have agreed not to transfer  HUBCO  Common  Stock
beneficially owned by them in violation of the pooling-of-interests restrictions
set forth above with respect to IBSF.

Amendments; Termination

         The Merger  Agreement  may be amended,  modified or  supplemented  with
respect to any of its terms by the mutual  consent of HUBCO and IBSF at any time
prior to the Effective Time. However,  after approval of the Merger Agreement by
the  shareholders  of IBSF, no amendment can be made which reduces the amount or
changes the form of  consideration  to be delivered to the  shareholders of IBSF
without the approval of such shareholders.

         The Merger  Agreement may be  terminated by the mutual  consent of IBSF
and HUBCO.  The Merger  Agreement  may also be  terminated  by IBSF or HUBCO if,
among  other  things,  (i) the  Effective  Time has not  occurred  on or  before
December 31, 1998 (the "Cutoff  Date") unless the failure of such  occurrence is
due to the failure of the party  seeking to  terminate to perform or observe its
covenants in the Merger  Agreement;  (ii) a vote of the  shareholders of IBSF to
approve the Merger Agreement is taken and such  shareholders fail to approve the
Merger Agreement at their meeting;  or (iii) any regulatory  approvals necessary
to consummate  the  transaction  have been denied or withdrawn at the request of
the regulatory agency or such approval is given with conditions which would have
a material adverse effect on HUBCO (but then only by HUBCO).

         HUBCO may terminate  the Merger  Agreement if there has been a material
adverse  change in the business,  operations,  assets or financial  condition of
IBSF and IBSF Bank,  taken as a whole,  from that  disclosed by IBSF to HUBCO in
its Annual  Report on Form 10-K for the year ended  December 31,  1997,  or IBSF
breaches  in a  material  respect  any  representation,  warranty  or  covenant,
agreement or obligation under the Merger Agreement and does not cure such breach
within  30 days  after  receipt  by IBSF of a notice of  breach.  HUBCO may also
terminate the Merger Agreement if the conditions to HUBCO's obligations to close
are not satisfied and are not capable of being satisfied by the Cutoff Date.

         IBSF may  terminate  the Merger  Agreement if there has been a material
adverse  change in the business,  operations,  assets or financial  condition of
HUBCO and its subsidiaries  taken as a whole from that disclosed by HUBCO in its
Annual  Report on Form 10-K for the year ended  December 31,  1997,  or if HUBCO
breaches  in a  material  respect  any  representation,  warranty  or  covenant,
agreement or obligation under the Merger Agreement and does not cure such breach
within 30 days after receipt by HUBCO of a notice of breach,  or if IBSF's Board
of Directors approves another  acquisition  transaction after determining,  upon
advice of counsel,  that approval was necessary in the exercise of its fiduciary
obligations  under applicable laws. IBSF may also terminate the Merger Agreement
if the  conditions  for IBSF to close are not  satisfied  and are not capable of
being satisfied by the Cutoff Date.

         In  addition,  the  Merger  Agreement  may be  terminated  by IBSF upon
occurrence  of a  Termination  Event,  as described  below under the caption "--
Termination Events".

         If the Merger Agreement is terminated,  the  transactions  contemplated
thereby will be abandoned  without further action by any party,  each party will
bear its own  expenses and each party will retain all rights and remedies it may
have at law or equity under the Merger Agreement.

Termination Events

         The  Merger  Agreement  may be  terminated  by  IBSF,  if  both  of the
following conditions are satisfied:

   

         (x)  the  Median  Pre-Closing  Price  of  HUBCO  Common  Stock  on  the
         Determination Date is less than $31.82 (the "HUBCO Floor Price"), which
         is 85% of the Closing Price of HUBCO Common Stock on April 1, 1998, the
         first  trading day after public  announcement  of the Merger  Agreement
         (the "Starting Date"); and

    

         (y) (i) the number (the "HUBCO Ratio")  obtained by dividing the Median
         Pre-Closing  Price of HUBCO Common Stock on the  Determination  Date by
         the HUBCO Common Stock Closing Price on the Starting Date, is less than
         (ii) the number (the  "Index  Ratio")  obtained by dividing  the KBW 50
         Index for the  Determination  Date by the KBW 50 Index for the Starting
         Date, and then subtracting 0.10.

         However,  if both  conditions (x) and (y) exist,  and the IBSF Board of
Directors  notifies  HUBCO that IBSF elects to terminate  the Merger  Agreement,
HUBCO will have the option to override  IBSF's  termination  by  increasing  the
Exchange Ratio to a number which equals the lesser of the following:

         (i) a  number  (rounded  to four  decimals)  equal to a  fraction,  the
         numerator of which is the HUBCO Floor Price  multiplied by the Exchange
         Ratio (as then in effect)  and the  denominator  of which is the Median
         Pre-Closing Price of HUBCO Common Stock on the Determination Date; or

         (ii) a number  (rounded  to four  decimals)  equal to a  quotient,  the
         numerator of which is the Index Ratio  multiplied by the Exchange Ratio
         (as then in effect) and the denominator of which is the HUBCO Ratio.

         If HUBCO so  elects  and  increases  the  Exchange  Ratio,  the  Merger
Agreement  will not be  terminated.  There  can be no  assurance  that IBSF will
exercise its right to terminate the Merger Agreement if the conditions described
above exist (a  "Termination  Event"),  and if IBSF does  exercise  its right to
terminate the Merger Agreement,  there can be no assurance that HUBCO will elect
to  increase  the  Exchange  Ratio as provided  in the Merger  Agreement  and as
described above.

         Certain  possible effects of the above provisions on the Exchange Ratio
may be illustrated by the following three  scenarios (all scenarios  assume that
the 0.534  Exchange  Ratio has not  previously  been  adjusted  pursuant  to the
anti-dilution provisions of the Merger Agreement):

   

                  (1) If the Median  Pre-Closing  Price of HUBCO Common Stock is
         equal to or greater than $31.82 (the HUBCO Floor Price), there would be
         no Termination Event and no adjustment to the Exchange Ratio.

                  (2) If the Median  Pre-Closing  Price of HUBCO Common Stock is
         less than $31.82 (the HUBCO Floor Price),  but the HUBCO Ratio is equal
         to or greater than the Index Ratio, there would be no Termination Event
         and no adjustment to the Exchange Ratio.

                  (3) If the Median  Pre-Closing  Price of HUBCO Common Stock is
         less than $31.82 (the HUBCO Floor  Price),  and the HUBCO Ratio is less
         than the Index Ratio, there would be a Termination Event and IBSF could
         elect to terminate the Merger Agreement.  However,  HUBCO could, at its
         sole option,  override the termination by increasing the Exchange Ratio
         to the lesser of the  following  two numbers  (in each case  rounded to
         four decimals):

                  (A) a fraction  in which the  numerator  is $16.99  (the HUBCO
                  Floor Price  multiplied by the 0.534  Exchange  Ratio) and the
                  denominator  is the Median  Pre-Closing  Price of HUBCO Common
                  Stock, or

    

                  (B) a  fraction  in which the  numerator  is the  Index  Ratio
                  multiplied by the 0.534 Exchange Ratio and the  denominator of
                  which is the HUBCO Ratio.

   

         It is not possible to know whether a Termination Event will occur until
after the  Determination  Date. IBSF has made no decision as to whether it would
exercise its right to terminate  the Merger  Agreement if there is a Termination
Event.  In  considering  whether  to  exercise  its  termination  right  in such
situation,  the IBSF Board of Directors  would,  consistent  with its  fiduciary
duties,  take into account all relevant  facts and  circumstances  that exist at
such time and would  consult  with its  financial  advisors  and legal  counsel.
Approval of the Merger Agreement by the shareholders of IBSF at the Meeting will
confer on the IBSF Board of Directors the power,  consistent  with its fiduciary
duties,  to elect to consummate the Merger following a Termination Event whether
or not there is any  increase  in the  Exchange  Ratio and  without  any further
action by, or  resolicitation  of, the  shareholders  of IBSF. If IBSF elects to
exercise  its  termination  right,  IBSF must give HUBCO  prompt  notice of that
decision during the five business day period commencing with (and including) the
first  business day following  the  Determination  Date,  provided that any such
notice of election to  terminate  by IBSF may be  withdrawn  by IBSF at any time
within the aforementioned five business day period.  During a three business-day
period  commencing  with its  receipt  of such  notice  from  the IBSF  Board of
Directors,  HUBCO  has the  option,  in its sole  discretion,  to  increase  the
Exchange  Ratio  in  the  manner  set  forth  in  the  Merger  Agreement  and as
illustrated above and thereby avoid  termination of the Merger Agreement.  HUBCO
is under no  obligation  to increase  the  Exchange  Ratio,  and there can be no
assurance  that HUBCO would elect to increase the Exchange Ratio if IBSF were to
exercise its right to  terminate  the Merger  Agreement as set forth above.  Any
decision  would be made by HUBCO in light of the  circumstances  existing at the
time HUBCO has the opportunity to make the election. If HUBCO elects to increase
the  Exchange  Ratio as set forth in the  Merger  Agreement  and as  illustrated
above,  it must give IBSF notice of that  election  within three  business  days
following  receipt of the  notice of  termination  from  IBSF,  in which case no
termination  of the Merger  Agreement  would occur as a result of a  Termination
Event.

    

         The  foregoing  discussion is qualified in its entirety by reference to
the applicable  provisions in the Merger Agreement (a copy of which is set forth
as Appendix A to this Proxy  Statement)  relating to a possible  increase of the
Exchange Ratio as the result of a Termination Event.

Accounting Treatment of the Merger

         The  Merger  is  expected  to be  accounted  for  by  HUBCO  under  the
pooling-of-interests  method of accounting in accordance with generally accepted
accounting  principles.  Each of HUBCO's and IBSF's obligation to consummate the
Merger is conditioned  upon HUBCO's  receipt of assurances  from its independent
public accountants,  Arthur Andersen LLP, that the Merger will be so treated. As
required by generally accepted accounting principles, under pooling-of-interests
accounting, as of the Effective Time the assets and liabilities of IBSF would be
added to those of HUBCO at their  recorded  book  values  and the  stockholders'
equity  accounts  of HUBCO and IBSF would be  combined  on HUBCO's  consolidated
balance sheet.  On a  pooling-of-interests  accounting  basis,  income and other
financial  statements of HUBCO issued after  consummation of the Merger would be
restated  retroactively to reflect the consolidated  combined financial position
and  results of  operations  of HUBCO and IBSF as if the Merger had taken  place
prior  to the  periods  covered  by such  financial  statements.  The pro  forma
financial  information contained in this Proxy Statement has been prepared using
the  pooling-of-interests  accounting basis to account for the Merger.  See "PRO
FORMA FINANCIAL INFORMATION".

Federal Income Tax Consequences

         The   following  is  a  discussion  of  certain   federal   income  tax
consequences  of the Merger but is not intended to be a complete  description of
such consequences.  The discussion is included for general information  purposes
only and may not apply to special situations, such as IBSF shareholders, if any,
who received  HUBCO Common Stock upon the exercise of employee  stock options or
otherwise as  compensation,  that hold IBSF Common Stock as part of a "straddle"
or  "conversion  transaction",  or  that  are  insurance  companies,  securities
dealers,  financial  institutions or foreign  persons,  and does not discuss any
aspects of state, local or foreign taxation. This discussion is based upon laws,
regulations,  rulings and decisions  now in effect and on proposed  regulations,
all of which are  subject  to  change  (possibly  with  retroactive  effect)  by
legislation,  administrative  action or judicial decision. No ruling has been or
will be requested from the Internal  Revenue  Service on any tax matter relating
to the tax consequences of the Merger.

         As an  exhibit  to the  Registration  Statement  of  which  this  Proxy
Statement  is a part,  Pitney,  Hardin,  Kipp & Szuch,  counsel  to HUBCO,  have
advised HUBCO and IBSF in an opinion that:

         (i) No gain or loss will be recognized  for federal income tax purposes
by IBSF  shareholders  upon the  exchange in the Merger of shares of IBSF Common
Stock  solely for HUBCO Common  Stock  (except with respect to cash  received in
lieu of a fractional share interest in HUBCO Common Stock).

         (ii) The basis of HUBCO  Common  Stock  received  in the Merger by IBSF
shareholders  (including  the basis of any  fractional  share  interest in HUBCO
Common  Stock) will be the same as the basis of the shares of IBSF Common  Stock
surrendered in exchange therefore.

         (iii) The holding  period of HUBCO Common Stock  (including the holding
period of any fractional  share interest in HUBCO Common Stock) will include the
holding  period  during  which the shares of IBSF Common  Stock  surrendered  in
exchange  therefore were held by the IBSF  stockholder,  provided such shares of
IBSF Common Stock were held as capital assets.

         (iv)  Cash  received  by a  holder  of IBSF  Common  Stock in lieu of a
fractional  share interest in HUBCO Common Stock will be treated as received for
such fractional  share interest,  and,  provided the fractional share would have
constituted  a capital  asset in the hands of such holder,  the holder should in
general  recognize  capital  gain or loss in an amount  equal to the  difference
between the amount of cash received and the portion of the adjusted tax basis in
IBSF Common Stock allocable to the fractional share interest.

         Consummation  of the Merger is  conditioned,  among  other  things,  on
receipt  by each of HUBCO and IBSF of an opinion  of their  respective  counsel,
dated the  Effective  Time,  to the effect  that,  as of such date,  the (i) the
Merger  will be treated  for federal  income tax  purposes  as a  reorganization
qualifying  under the provisions of Section 368 of the Internal  Revenue Code of
1986, as amended; (ii) no gain or loss will be recognized by IBSF; (iii) no gain
or loss will be recognized by the holders of IBSF Common Stock upon the exchange
of IBSF Common Stock solely for HUBCO  Common  Stock;  (iv) the tax basis of any
HUBCO  Common  Stock  received in exchange for IBSF Common Stock shall equal the
basis of the recipient's IBSF Common Stock surrendered on the exchange;  and (v)
the holding  period for any HUBCO  Common  Stock  received in exchange  for IBSF
Common Stock will include the period during which IBSF Common Stock  surrendered
on the exchange was held,  provided  such stock was held as a capital  assets on
the date of the exchange.  Unlike a ruling from the Internal Revenue Service, an
opinion of counsel is not binding on the Internal  Revenue,  Service,  and there
can be no assurance that the Internal  Revenue  Service will not take a position
contrary to one or more of the positions  reflected herein or that the positions
herein  will be  upheld by the  courts if  challenged  by the  Internal  Revenue
Service. While HUBCO and IBSF have the contractual right to waive this condition
to  closing,  neither  will do so,  and the  Merger  will not take  place if the
opinions are not obtained.

         The opinions of Pitney,  Hardin,  Kipp & Szuch  summarized above are or
will be based, among other things, on representations  contained in certificates
of officers of IBSF and HUBCO.

         BECAUSE CERTAIN TAX  CONSEQUENCES OF THE MERGER MAY VARY DEPENDING UPON
THE  PARTICULAR  CIRCUMSTANCES  OF EACH HOLDER OF IBSF COMMON  STOCK,  AND OTHER
FACTORS,  EACH SUCH HOLDER IS URGED TO CONSULT SUCH  HOLDER'S OWN TAX ADVISOR TO
DETERMINE  THE  PARTICULAR  TAX  CONSEQUENCES  TO  SUCH  HOLDER  OF  THE  MERGER
(INCLUDING  THE  APPLICATION  AND EFFECT OF STATE AND LOCAL INCOME AND OTHER TAX
LAWS

         Consequences  of Receipt  of Cash in Lieu of  Fractional  Shares.  Cash
received by an IBSF shareholder in lieu of any fractional share interest will be
treated as having been received as a payment in  redemption  of such  fractional
share interest as if a fractional share of HUBCO Common Stock had been issued in
the Merger and then redeemed by HUBCO,  and, provided the fractional share would
have  constituted  a  capital  asset  in the  hands  of  such  shareholder,  the
shareholder  should in general recognize capital gain or loss in an amount equal
to the  difference  between the amount of cash  received  and the portion of the
adjusted basis in IBSF Common Stock allocable to the fractional share interest.

         Basis of HUBCO Common Stock.  The basis of HUBCO Common Stock  received
by an IBSF  shareholder  who receives solely HUBCO Common Stock will be the same
as the basis of such  shareholder's  IBSF Common Stock  surrendered  in exchange
therefor.

         Holding  Period.  The holding  period of shares of HUBCO  Common  Stock
received in the Merger by holders of IBSF Common  Stock will  include the period
during which such shares of IBSF Common Stock  surrendered in exchange  therefor
were held by the holder thereof,  provided such shares of IBSF Common Stock were
held as capital assets.

No Dissenters' Rights

         Under the NJBCA,  holders of IBSF Common Stock do not have  dissenters'
rights of appraisal in connection with the Merger.

                         PRO FORMA FINANCIAL INFORMATION

              Pro Forma Unaudited Combined Condensed Balance Sheet
                                of HUBCO and IBSF

   

         The  following pro forma  unaudited  combined  condensed  balance sheet
combines the  historical  consolidated  balance  sheets of HUBCO  (restated  and
adjusted as described  below) and IBSF giving effect to the Merger which will be
accounted for as a pooling of interests,  as if the Merger had been effective on
March 31, 1998 and the pro forma adjustments described in the notes to pro forma
financial information.  The financial information for HUBCO has been restated to
include the effects of the merger with TBOS which was consummated on January 12,
1998 and has  been  accounted  for as a  pooling  of  interests.  The  financial
information for HUBCO has also been adjusted to give pro forma effect to the PFC
and MSB mergers,  which closed on April 24 and May 29, 1998,  respectively,  and
each of which will be accounted for as a pooling of interests.  The  information
set forth below should be read in conjunction  with the historical  consolidated
financial  statements  of HUBCO  and  IBSF,  including  their  respective  notes
thereto,  as well as the historical and pro forma  information  for PFC and MSB,
which are incorporated by reference in this Proxy Statement-Prospectus.  HUBCO's
fiscal year ends  December 31 and IBSF's  fiscal year ends  September 30. In the
following  table,  financial  data for the fiscal years ended December 31, 1997,
1996 and 1995 includes IBSF financial data for the 12 months ended September 30,
1997, 1996 and 1995, respectively,  and information regarding HUBCO is presented
consistent  with the fiscal year of HUBCO ended December 31. The information for
the three  months  ended  March 31, 1998 is based on the  respective  historical
unaudited  financial  statements of HUBCO  (restated and adjusted) and IBSF. The
pro forma financial information does not give effect to anticipated cost savings
net of expected Merger related expenses and restructuring charges. The pro forma
financial  statements of HUBCO included in this Proxy  Statement-Prospectus  are
not restated to reflect the Completed Branch Purchase or the Recently  Completed
Trust  Preferred  Offering  and do not  reflect the  Pending  Acquisitions.  The
historical amounts presented in future financial statements of HUBCO for periods
reported in this Proxy  Statement-Prospectus  will differ and in certain  cases,
will differ  materially as a result of the effects of accounting  for the Merger
and  certain  of the  Pending  Acquisitions,  when  consummated,  as  pooling of
interests.  See "CERTAIN INFORMATION REGARDING HUBCO - Recent Developments." The
pro forma information is not necessarily indicative of the results of operations

         Pro Forma Unaudited Combined Condensed Statements of Income of
                                 HUBCO and IBSF

   

         The  following pro forma  unaudited  combined  condensed  statements of
income  combine  the  historical  consolidated  statements  of  income  of HUBCO
(restated and adjusted as described  below) and IBSF giving effect to the Merger
which  will be  accounted  for as a  pooling-of-interests,  as if the Merger had
occurred on the first day of the applicable  periods indicated  herein,  and the
pro forma adjustments described in the notes to the pro forma combined financial
statements. The financial information for HUBCO has been restated to include the
effects of the merger  with TBOS which was  consummated  on January 12, 1998 and
has been accounted for as a pooling of interests.  The financial information for
HUBCO  has also  been  adjusted  to give  pro  forma  effect  to the PFC and MSB
mergers,  which closed on April 24 and May 29, 1998,  respectively,  and each of
which were accounted for as a pooling of interests.  The  information  set forth
below should be read in conjunction with the condensed  consolidated  historical
and  other  pro  forma  financial  information,  including  the  notes  thereto,
incorporated    by   reference   or   appearing    elsewhere   in   this   Proxy
Statement-Prospectus.  The pro forma financial  information does not give effect
to  anticipated  cost  savings  net of  expected  Merger  related  expenses  and
restructuring  charges.  The pro forma financial statements of HUBCO included in
this Proxy Statement-Prospectus are not restated to reflect the Completed Branch
Purchase or the Recently  Completed Trust Preferred  Issuance and do not reflect
the Pending  Acquisitions.  The historical amounts presented in future financial
statements of HUBCO for periods reported in this Proxy Statement-Prospectus will
differ and in certain cases,  will differ  materially as a result of the effects
of  accounting  for the Merger and  certain of the  Pending  Acquisitions,  when
consummated, as pooling of interests. See "CERTAIN INFORMATION REGARDING HUBCO -
Recent Developments." The pro forma information is not necessarily indicative of
the results of  operations  which would have been  achieved  had the Merger been
consummated as of the beginning of the periods for which such data are presented
and should not be  construed  as being  representative  of future  periods.  The
financial  information  also  does  not  reflect  one-time  merger  related  and
restructuring  charges  which either have been or will be incurred in connection
with  the  Merger  and  the   Recently   Completed   Acquisitions   and  Pending
Acquisitions.

Notes to Pro Forma Financial Information

(1)      Pro forma financial  information  assumes the Merger was consummated as
         of  March  31,  1998 for the pro  forma  unaudited  combined  condensed
         balance sheet and as of the beginning of each of the periods  indicated
         for the pro forma unaudited  combined  condensed  statements of income.
         The pro forma  information  presented is not necessarily  indicative of
         the results of operations or the combined financial position that would
         have resulted had the Merger been  consummated  at the beginning of the
         periods indicated,  nor is it necessarily  indicative of the results of
         operations in future  periods or the future  financial  position of the
         combined entities.

(2)      It  is  assumed   that  the  Merger   will  be   accounted   for  on  a
         pooling-of-interests accounting basis, and accordingly, the related pro
         forma adjustments herein reflect,  where applicable,  an Exchange Ratio
         of 0.534 shares of HUBCO Common Stock for each of the  10,959,674  (net
         of 650,049 treasury shares held) shares of IBSF Common Stock which were
         outstanding at March 31, 1998.

(3)      The pro forma financial  information  presented  herein gives effect to
         the  cancellation of 650,049 shares of IBSF Common Stock held in IBSF's
         treasury at a cost of $10,106,000.



In  summary,  the pro forma  information  reflects  adjustments  for the  Merger
accounted  for using the  pooling-of-interests  accounting  method  assuming the
0.534 Exchange Ratio, as follows:

                            THE ADJOURNMENT PROPOSAL

         Each  proxy  solicited  hereby  requests   authority  to  vote  for  an
adjournment of the Meeting,  if an  adjournment is deemed to be necessary.  IBSF
may seek an  adjournment  of the  Meeting  for not more than 29 days in order to
enable IBSF to solicit  additional  votes in favor of the  proposal to adopt the
Merger  Agreement in the event that such proposal has not received the requisite
vote of  stockholders  at the Meeting and such  proposal  has not  received  the
negative  votes of the  holders  of a majority  of IBSF  Common  Stock.  If IBSF
desires to adjourn the meeting with respect to such proposal,  it will request a
motion  that the  meeting be  adjourned  for up to 29 days with  respect to such
proposal, and no vote will be taken on such proposal at the originally scheduled
Meeting.  Each proxy solicited  hereby,  if properly signed and returned to IBSF
and not revoked prior to its use, will be voted on any motion for adjournment in
accordance with the instructions  contained therein. If no contrary instructions
are given,  each proxy  received will be voted in favor of any motion to adjourn
the  meeting.  Unless  revoked  prior to its use,  any proxy  solicited  for the
Meeting will continue to be valid for any  adjournment of the Meeting,  and will
be voted in accordance with instructions  contained therein,  and if no contrary
instructions are given, for the proposal in question.

         Any adjournment will permit IBSF to solicit additional proxies and will
permit a greater  expression  of the  stockholders'  views  with  respect to the
Merger proposal.  Such an adjournment would be  disadvantageous  to stockholders
who are  against  the Merger  proposal,  because an  adjournment  will give IBSF
additional  time to solicit  favorable  votes and thus  increase  the chances of
passing the Merger proposal.

         If a quorum is not present at the  Meeting,  no proposal  will be acted
upon and the Board of Directors of IBSF will adjourn the Meeting to a later date
in order to solicit  additional proxies on each of the proposals being submitted
to stockholders.

         An adjournment for up to 29 days will not require either the setting of
a new  record  date or  notice  of the  adjourned  meeting  as in the case of an
original  meeting.  IBSF has no reason to  believe  that an  adjournment  of the
Meeting will be necessary at this time.

         Because the Board of Directors  recommends that  stockholders  vote FOR
the proposal to adopt the Merger  Agreement,  as discussed  above,  the Board of
Directors  recommends that stockholders vote FOR the possible adjournment of the
Meeting.  The holders of a majority of the IBSF Common Stock present,  in person
or by proxy,  at the Meeting will be required to approve a motion to adjourn the
Meeting.

(1)      For  purposes of this table,  pursuant to rules  promulgated  under the
         Exchange Act, an individual is considered to beneficially own shares of
         IBSF Common Stock if he or she directly or indirectly has or shares (1)
         voting power,  which includes the power to vote or to direct the voting
         of the shares;  or (2)  investment  power,  which includes the power to
         dispose or direct  the  disposition  of the  shares.  Unless  otherwise
         indicated,  an  individual  has sole voting  power and sole  investment
         power with respect to the indicated shares.

(2)      Under  applicable  regulations,  a person is deemed to have  beneficial
         ownership  of any shares of IBSF  Common  Stock  which may be  acquired
         within 60 days of June 12, 1998 pursuant to the exercise of outstanding
         stock  options.  Shares of IBSF Common Stock which are subject to stock
         options are deemed to be  outstanding  for the purpose of computing the
         percentage  of  outstanding  IBSF Common  Stock owned by such person or
         group but not  deemed  outstanding  for the  purpose of  computing  the
         percentage of IBSF Common Stock owned by any other person or group.

   

(3)      The IBS Financial  Corp.  Employee Stock Ownership Plan Trust ("Trust")
         was  established  pursuant to the IBS Financial  Corp.  Employee  Stock
         Ownership  Plan ("ESOP") by an agreement  between IBSF and the trustees
         of the ESOP  ("Trustees").  The current  Trustees  are Messrs.  Borden,
         Gleason and Stiles. As of June 12, 1998,  609,845 shares of IBSF Common
         Stock held in the Trust were  unallocated  and 584,356  shares had been
         allocated to the accounts of participating  employees.  Under the terms
         of the ESOP, the Trustees will generally vote the allocated shares held
         in the ESOP in accordance with the  instructions  of the  participating
         employees and will generally vote  unallocated  shares held in the ESOP
         in the same proportion for and against proposals to stockholders as the
         ESOP participants and beneficiaries actually vote shares of IBSF Common
         Stock allocated to their individual  accounts,  subject in each case to
         the  fiduciary  duties of the ESOP  trustees  and  applicable  law. Any
         allocated  shares which either abstain on the proposal or are not voted
         will be disregarded  in  determining  the percentage of stock voted for
         and against each proposal by the  participants and  beneficiaries.  The
         amount of IBSF Common Stock  beneficially  owned by directors who serve
         as trustees of the ESOP and by all directors and executive  officers as
         a group does not include the unallocated shares held by the Trust.

(4)      Includes 13,073 unvested shares granted to each  non-employee  director
         (other  than  Mr.  Abramowitz)   pursuant  to  IBSF's  Recognition  and
         Retention Plan and Trust ("Recognition Plan"), which shares maybe voted
         by each director,  and 73,431 shares (67,681 shares for Mr. Gleason and
         none for Mr.  Abramowitz)  which may be acquired  upon the  exercise of

                       DESCRIPTION OF HUBCO CAPITAL STOCK

General

         The authorized  capital stock of HUBCO presently consists of 53,045,000
shares of HUBCO Common Stock and 10,300,000 shares of preferred stock. As of May
31, 1998, 28,491,159  shares of HUBCO Common Stock were issued and  outstanding,
and 500 shares of HUBCO Series B Preferred Stock were outstanding.

         Under the terms of HUBCO's  Certificate of Incorporation,  the Board of
Directors has  authority at any time (i) to divide any or all of the  authorized
but  unissued   shares  of  preferred   stock  into  series  and  determine  the
designations,  number of shares, relative rights, preferences and limitations of
any such  series and (ii) to  increase  the number of shares of any such  series
previously determined by it and to decrease such previously determined number of
shares  to a  number  not less  than  that of the  shares  of such  series  then
outstanding.  HUBCO Series A Convertible  Preferred Stock was issued pursuant to
such authority in connection  with HUBCO's  acquisition  of Washington  Bancorp,
Inc. on July 1, 1994; no HUBCO Series A Preferred Stock remains outstanding.  In
December,  1996, as part of the  acquisition of Westport  Bancorp,  Inc.,  HUBCO

         HUBCO's Certificate of Incorporation  authorizes the Board of Directors
of HUBCO (except in connection with certain business combinations), from time to
time and without further  shareholder  action, to issue new shares of authorized
but  unissued  HUBCO  Common  Stock or  preferred  stock.  Because  of its broad
discretion  with  respect to the  creation and issuance of HUBCO Common Stock or
preferred  stock  without  shareholder  approval,  the Board of Directors  could
adversely  affect the voting power of holders of HUBCO Common Stock or preferred
stock and, by issuing shares of preferred stock with certain voting,  conversion
and/or redemption rights, could discourage any attempt to gain control of HUBCO.

Description of HUBCO Common Stock

         The following  description of the HUBCO Common Stock sets forth certain
general terms of the HUBCO Common Stock. For an additional  description relating
to the HUBCO Common Stock, see "COMPARISON OF THE RIGHTS OF SHAREHOLDERS OF IBSF
AND HUBCO".

         Dividend Rights

         The holders of HUBCO Common  Stock are  entitled to receive  dividends,
when, as and if declared by the Board of Directors of HUBCO out of funds legally
available therefore subject to the preferential dividend rights of any preferred
stock  that may be  outstanding.  The only  statutory  limitation  is that  such
dividends may not be paid when HUBCO is insolvent. Because funds for the payment
of  dividends  by  HUBCO  come  primarily  from the  earnings  of  HUBCO's  bank
subsidiaries,  as a practical matter,  restrictions on the ability of those bank
subsidiaries  to pay  dividends  act as  restrictions  on the  amount  of  funds
available for the payment of dividends by HUBCO.

         As a New  Jersey  chartered  commercial  bank,  HUB is  subject  to the
restrictions on the payment of dividends  contained in the NJBA. Under the NJBA,
HUB may pay dividends only out of retained  earnings,  and out of surplus to the
extent that surplus exceeds 50% of stated capital.  Under the CBL, Lafayette may
pay dividends  only from its net profits,  and the total of all dividends in any
calendar year may not (unless specifically  approved by the Commissioner) exceed
the total of its net profits of that year combined with its retained net profits
of the preceding two years.  Under the Financial  Institutions  Supervisory Act,
the FDIC has the authority to prohibit a  state-chartered  bank from engaging in
conduct which, in the FDIC's  opinion,  constitutes an unsafe or unsound banking
practice. Under certain circumstances,  the FDIC could claim that the payment of
a dividend or other  distribution  by HUB or Lafayette to HUBCO  constitutes  an
unsafe or unsound  practice.  In addition,  BTH, HUBCO's  recently  acquired New
York-based  bank  will  serve as an  additional  source of  dividends  to HUBCO.
Payment of any such  dividends by BTH will be subject to the  regulations of the
OTS, if BTH continues to be federally-chartered, or the New York Banking Law, if
the BTH  converts to a New York  State-chartered  bank.  Under the Office of the
Thrift  Supervision  Regulations  (the "OTSR"),  BTH may pay  dividends up to an
amount  equal to one  hundred  percent  of its net  income  to date  during  the
calendar year plus the amount that would reduce by one-half its surplus  capital
ratio  at the  beginning  of the  calendar  year  or up to an  amount  equal  to
seventy-five percent of its net income over the most recent four-quarter period,
provided in each case that if  immediately  after giving effect to such proposed
dividend (on a pro forma  basis),  BTH's capital is equal to or greater than the
amount of its regulatory capital requirement.

         HUBCO is also  subject to certain  FRB  policies  which may, in certain
circumstances,  limit its ability to pay  dividends.  The FRB policies  require,
among other things, that a bank holding company maintain a minimum capital base.
The FRB would most likely  seek to prohibit  any  dividend  payment  which would
reduce a holding company's capital below these minimum amounts.

         At March 31, 1998, HUB had $130.1 million  available for the payment of
dividends  to  HUBCO,  and as of March  31,  1998,  Lafayette  had $1.7  million
available for the payment of dividends to HUBCO,  and as of March 31, 1998,  BTH
had $9.7  million  available  for the payment of  dividends.  At March 31, 1998,
HUBCO had $104.0 million  available for  shareholder  dividends,  the payment of
which would not reduce any of its capital  ratios  below the minimum  regulatory
requirements.

         Voting Rights

         At meetings of shareholders, holders of HUBCO Common Stock are entitled
to one vote per share.  The quorum for  shareholders'  meetings is a majority of
the  outstanding  shares  entitled  to vote  represented  in person or by proxy.
Except as indicated below, all actions and  authorizations  to be taken or given
by shareholders  require the approval of a majority of the votes cast by holders
of HUBCO Common Stock at a meeting at which a quorum is present.

         The Board of Directors is divided into three classes of directors, each
class being as nearly equal in number of  directors  as possible.  Approximately
one-third  of the  entire  Board  of  Directors  is  elected  each  year and the
directors serve for terms of up to three years,  and, in all cases,  until their
respective successors are duly elected and qualified.

         The exact number of directors and the number constituting each class is
fixed from time to time by resolution  adopted by a majority of the entire Board
of Directors.  Shareholders  may remove any director from office for cause.  The
affirmative vote of at least  three-quarters  of the shares of HUBCO entitled to
vote  thereon  is  required  to  amend  or  repeal  the  provisions  of  HUBCO's
Certificate  of  Incorporation  relating to the  classification  of the Board of
Directors and the removal of directors.

         HUBCO's  Certificate  of  Incorporation   contains  a  "minimum  price"
provision. If a "related person" (defined in the Certificate of Incorporation to
include persons who, together with their affiliates,  own 10% or more of HUBCO's
Common Stock)  proposes to enter into a Business  Combination (as defined in the
Certificate of Incorporation) with HUBCO, the proposed  transaction will require
the  affirmative  vote of at  least  three-quarters  of the  outstanding  shares
entitled to vote on the transaction,  unless either (i) the proposed transaction
is first  approved  by a majority  of HUBCO's  Board of  Directors,  or (ii) the
shareholders  of HUBCO are  offered  consideration  in an amount  equal to or in
excess of an amount  determined  in accordance  with a formula  contained in the
Certificate  of  Incorporation.  If either of these tests are met,  the proposed
transaction  need only be approved by the vote  otherwise  required by law,  the
Certificate  of  Incorporation  and any  agreement  with a  national  securities
exchange.

         Liquidation Rights

         In a liquidation, holders of HUBCO Common Stock are entitled to receive
ratably  any  assets  distributed  to  shareholders,  except  that if  shares of
preferred stock of HUBCO are outstanding at the time of liquidation, such shares
of preferred stock may have prior rights upon liquidation.

         Assessment and Redemption

         All  outstanding  shares  of HUBCO  Common  Stock  are  fully  paid and
nonassessable.  HUBCO Common Stock is not redeemable at the option of the issuer
or the holders thereof.

         Preemptive and Conversion Rights

         Holders  of  HUBCO  Common  Stock  do not  have  conversion  rights  or
preemptive rights with respect to any securities of HUBCO.

Description of HUBCO Preferred Stock

         General

         Five  hundred  shares of HUBCO  Series B  Convertible  Preferred  Stock
("HUBCO Series B Preferred Stock") remain  outstanding as of March 31, 1998. The
following is a description of the existing HUBCO Series B Preferred Stock.

         HUBCO Series B Preferred Stock

         Dividend  Rights.  The holders of HUBCO  Series B  Preferred  Stock are
entitled to receive, when, as and if declared by the Board of Directors of HUBCO
out of funds legally available  therefore,  dividends at a rate to be determined
by the  Corporation's  Board of Directors.  All dividends  declared on the HUBCO
Series B  Preferred  Stock are pro rata per share  and  noncumulative.  The only
statutory  limitation  is that  such  dividends  may not be paid  when  HUBCO is
insolvent.

         Liquidation  Rights.  The holders of HUBCO Series B Preferred Stock are
entitled to receive $100.00 per share in any liquidation, dissolution or winding
up of HUBCO, subject to the rights of creditors.  In a liquidation,  dissolution
or winding  up, the  preferential  amounts  with  respect to the HUBCO  Series B
Preferred  Stock and any stock on parity with HUBCO  Series B  Preferred  Stock,
shall be  distributed  pro rata in accordance  with the  aggregate  preferential
amounts of the HUBCO Series B Preferred Stock and such stock on parity,  if any,
out of or to the extent of the net assets of HUBCO  legally  available  for such
distribution  before any distributions are made with respect to any stock junior
to the rights of HUBCO Series B Preferred Stock.

         Redemption. The HUBCO Series B Preferred Stock is not redeemable at the
option of the issuer or the holders thereof.

         Preemptive and Conversion  Rights.  Holders of HUBCO Series B Preferred
Stock  have an option to convert  such  stock into fully paid and  nonassessable
shares of HUBCO Common  Stock.  As of March 31, 1998,  the  conversion  rate was
33.2175 shares of Common Stock for each share of HUBCO Series B Preferred  Stock
(the  "Conversion  Ratio").  The Conversion  Ratio is subject to adjustment upon
certain events,  including the issuance of HUBCO Common Stock as a dividend with
respect to the  outstanding  HUBCO Common Stock,  subdivision or combinations of
HUBCO Common Stock,  the issuance to holders of HUBCO Common Stock  generally of
rights or warrants to subscribe for HUBCO Common Stock,  or the  distribution to
holders of HUBCO Common Stock  generally  of evidences of  indebtedness,  assets
(excluding  dividends in cash out of retained earnings) or rights or warrants to
subscribe  for   securities  of  HUBCO  other  than  those   mentioned   herein.
Notwithstanding the foregoing, the Conversion Ratio is not subject to adjustment
to the  extent  HUBCO  issues  any HUBCO  Common  Stock in  connection  with any
employee compensation and benefits plans, employee agreements and contracts.

         Voting Rights. Holders of shares of HUBCO Series B Preferred Stock vote
together  as a class with  holders of HUBCO  Common  Stock for the  election  of
directors  and all other  matters  to which  holders of HUBCO  Common  Stock are
entitled to vote.  Each share of HUBCO Series B Preferred Stock is entitled to a
number of votes equal to the  Conversion  Ratio as the same may be adjusted from
time to time.


                    COMPARISON OF THE RIGHTS OF SHAREHOLDERS
                                OF IBSF AND HUBCO

General

         Each of IBSF and HUBCO is a business corporation incorporated under the
NJBCA. The rights of IBSF  shareholders are currently  governed by the NJBCA and
IBSF's  certificate of  incorporation  and by-laws.  At the Effective Time, each
IBSF  shareholder  will  become a  shareholder  of  HUBCO.  The  rights of HUBCO
shareholders are governed by the NJBCA and HUBCO's  certificate of incorporation
and by-laws.  The following is a comparison  of certain  provisions of the NJBCA
and the respective  certificates of incorporation and by-laws of IBSF and HUBCO.
This summary does not purport to be complete and is qualified in its entirety by
reference to the NJBCA, which may change from time to time, and the certificates
of incorporation and by-laws of HUBCO and IBSF, which also may be changed.

Voting Requirements

         Under the NJBCA,  unless a greater vote is specified in the certificate
of  incorporation,  the amendment to the certificate of  incorporation  of a New
Jersey corporation,  the voluntary  dissolution of the corporation,  the sale or
other  disposition of all, or substantially all of the assets of the corporation
other than in the ordinary course of business or the merger or  consolidation of
the corporation with another  corporation,  requires in each case, a majority of
the votes cast by shareholders of the corporation  entitled to vote thereon. The
HUBCO Certificate requires the affirmative vote of 75% of the outstanding shares
entitled to vote on certain transactions  involving "related persons" unless the
proposed  transaction  is either first approved by a majority of the HUBCO Board
or the shareholders of HUBCO are offered  consideration in an amount equal to or
in excess of an amount  determined in accordance with a formula contained in the
HUBCO  Certificate.  See  "DESCRIPTION  OF HUBCO CAPITAL STOCK -- Description of
HUBCO Common Stock -- Voting Rights."

         The IBSF Certificate of Incorporation  requires the affirmative vote of
the holders of (1) at least 80% of the  outstanding  IBSF stock that is entitled
to vote  generally  in an  election of  directors  ("Voting  Shares")  and (2) a
majority  of the  outstanding  Voting  Shares that are not  beneficially  owned,
directly  or  indirectly,  by any  person  or  group  ("Related  Person")  which
beneficially  owns 10% or more of the Voting  Shares  ("Independent  Majority of
Stockholders") to approve certain transactions involving a Related Person unless
either (a) the IBSF shareholders are offered consideration in an amount equal to
or in excess of an amount  determined in accordance with a formula  contained in
the IBSF  Certificate  and certain other  conditions are  satisfied,  or (b) the
transaction is recommended to  shareholders  by at least  two-thirds of the IBSF
Board of  Directors  and by a majority of the  directors  unaffiliated  with any
Related Person. Because the IBSF Board of Directors has unanimously  recommended
that  shareholders  vote in favor of the Merger  Agreement,  this  supermajority
voting provision is not applicable to the Merger.

         The  IBSF   Certificate  of   Incorporation   also  provides  that  the
affirmative  vote of (1) the holders of at least 80% of the  outstanding  Voting
Shares, (2) an Independent  Majority of Stockholders,  and (3) any class of IBSF
preferred  stock that may be outstanding and entitled to vote (no such preferred
stock is currently  outstanding) is required to amend,  adopt,  alter, change or
repeal any provision  inconsistent  with Articles 6 (no  preemptive  rights),  7
(directors),  9 (meetings of shareholders,  director nominations and shareholder
proposals), 10 (bylaws), 11 (indemnification of officers,  directors,  employees
and  agents)  and  12  (amendment).   In  addition,  any  amendment,   addition,
alteration,  change or  repeal  of all or any  portion  of  Article  8  (certain
business  combinations  and acquisitions of stock) requires the affirmative vote
of (i) the holders of at least 80% of the outstanding  Voting Shares and (ii) an
Independent  Majority of  Stockholders,  unless such proposal is  recommended to
shareholders by at least  two-thirds of the whole Board of Directors of IBSF and
a majority of the directors unaffiliated with any Related Person.

Removal of Directors; Number of Directors

         The  NJBCA  allows  for the  removal  of  directors  for  cause  by the
affirmative  vote of the  majority  of the votes  cast by the  holders of shares
entitled  to  vote  for  the  election  of  directors.  HUBCO's  Certificate  of
Incorporation  states that  shareholders  may remove a director from office only
for cause.  HUBCO's  Certificate of  Incorporation  also allows  shareholders to
increase  or  decrease  the number of  directors  constituting  the Board by the
affirmative vote of at least  three-quarters of all of the outstanding shares of
common stock entitled to vote.

         The IBSF  Certificate of  Incorporation  provides that directors may be
removed from office only with cause by an affirmative vote of the holders of not
less than 80% of the  outstanding  Voting  Shares at a meeting  of  shareholders
called expressly for such purpose.  In addition,  at least 30 days prior to such
meeting of  shareholders,  written  notice must be given to the  director  whose
removal will be considered at the meeting.

         The IBSF  Certificate  of  Incorporation  provides  that the  number of
directors that shall  constitute the initial Board of Directors  shall be seven.
IBSF's Bylaws provide that the number of directors may be increased or decreased
by the  affirmative  vote of  two-thirds  of the whole Board of Directors  and a
majority of the directors  unaffiliated  with any Related Person,  provided that
the number of directors may not be less than five nor more than fifteen.

Preferred Stock

         The authorized  capital stock of HUBCO consists of 53,045,000 shares of
HUBCO Common Stock and 10,300,000 shares of preferred stock. As of May 31, 1998,
28,491,159  shares of HUBCO  Common Stock were issued and  outstanding,  and 500
shares of HUBCO Series B Preferred  Stock were  outstanding.  Under the terms of
the HUBCO  Certificate  of  Incorporation,  the HUBCO Board has authority at any
time to divide any or all of the  authorized  but  unissued  shares of preferred
stock into  series,  determine  the  designations,  number of  shares,  relative
rights,  preferences,  and  limitations  of any such  series and  authorize  the
issuance of such series. See "DESCRIPTION OF HUBCO CAPITAL STOCK -- General."

         The authorized  capital stock of IBSF consists of 20,000,000  shares of
IBSF Common Stock and 5,000,000 shares of serial preferred stock, $.01 par value
per share ("IBSF Preferred Stock").  As of April 30, 1998,  10,960,978 shares of
IBSF Common Stock were issued and  outstanding  and no shares of IBSF  Preferred
Stock were issued and  outstanding.  Under the terms of the IBSF  Certificate of
Incorporation,  the IBSF Board has authority at any time to divide any or all of
the  authorized  but  unissued  shares  of IBSF  Preferred  Stock  into  series,
determine the designations,  number of shares, relative rights, preferences, and
limitations of any such series and authorize the issuance of such series.

Classified Board of Directors

         The NJBCA permits a New Jersey  corporation to provide for a classified
board. HUBCO currently has a classified Board of Directors. The Board is divided
into  three  classes,  with  one  class of  directors  generally  elected  for a
three-year term at each annual meeting.

         The IBSF Certificate of  Incorporation  provides that the IBSF Board of
Directors  shall be  divided  into four  classes  as  nearly  equal in number as
possible, with one class to be elected annually for a four-year term.

Shareholder Consent to Corporate Action

         Except as otherwise  provided by the certificate of incorporation  (and
the HUBCO Certificate  presently is silent on this issue), the NJBCA permits any
action  required  or  permitted  to be taken at any  meeting of a  corporation's
shareholders, other than the annual election of directors, to be taken without a
meeting upon the written consent of shareholders who would have been entitled to
cast the minimum number of votes necessary to authorize such action at a meeting
of  shareholders  at which all  shareholders  entitled to vote were  present and
voting.  The annual  election of directors,  if not conducted at a shareholders'
meeting,  may only be effected by unanimous written consent.  Under the NJBCA, a
shareholder  vote on a plan of merger or  consolidation,  if not  conducted at a
shareholders'  meeting,  may only be effected by either:  (i) unanimous  written
consent of all shareholders entitled to vote on the issue with advance notice to
any other  shareholders,  or (ii) written consent of shareholders who would have
been entitled to cast the minimum  number of votes  necessary to authorize  such
action at a meeting,  together  with advance  notice to all other  shareholders.
HUBCO's By-laws provide that a special meeting of shareholders may be called for
any  purpose  by the  Chairman  of the  Board,  the  President  or the  Board of
Directors.

         The IBSF Certificate of Incorporation provides that any action required
to be taken at a meeting of shareholders or any action  permitted to be taken at
a meeting of shareholders  may be taken without a meeting if consent in writing,
setting  forth the action so taken,  shall be signed by all of the  shareholders
who would be entitled to vote at a meeting.  Except as otherwise required by the
NJBCA, the IBSF  Certificate  provides that special meetings of shareholders may
be  called  only  by (1) the  Board  of  Directors  by the  affirmative  vote of
two-thirds  of the whole  Board of  Directors  and a majority  of the  directors
unaffiliated  with any Related Person,  (2) the Chairman of the Board or (3) the
President of IBSF.

Dividends

         Unless there are other  restrictions  contained in its  certificate  of
incorporation  (and the HUBCO  Certificate  presently  contains none), the NJBCA
generally  provides that a New Jersey  corporation may declare and pay dividends
on its  outstanding  stock so long as the corporation is not insolvent and would
not become insolvent as a consequence of the dividend payment. Because funds for
the payment of  dividends by HUBCO come  primarily  from the earnings of HUBCO's
bank subsidiaries,  as a practical matter, restrictions on the ability of HUB or
Lafayette to pay dividends act as  restrictions on the amount of funds available
for  the  payment  of  dividends  by  HUBCO.  At  March  31,  1998,   HUBCO  had
approximately  $104.0  million  available  for  shareholder  dividends.   For  a
description  of the  regulatory  restrictions  on  dividend  payments by HUB and
Lafayette,  see  "DESCRIPTION  OF HUBCO  CAPITAL STOCK --  Description  of HUBCO
Common Stock -- Dividend Rights."

         IBSF's  Bylaws  provide that  dividends may be declared by the Board of
Directors and paid by IBSF out of the unreserved and unrestricted earned surplus
of IBSF,  subject to the conditions and limitations  imposed by the NJBCA. Based
on IBSF's earned surplus at March 31, 1998, IBSF had approximately $33.4 million
available for dividends to  shareholders  at such date.  However,  funds for the
payment of  dividends by IBSF are  primarily  derived  from  dividends  from the
Association to IBSF. As a result, restrictions on the ability of the Association
to pay dividends act as  restrictions  on the amount of funds  available for the
payment of dividends by IBSF.

By-laws

         Under the NJBCA, the board of directors of a New Jersey corporation has
the power to adopt,  amend,  or repeal the  corporation's  by-laws,  unless such
powers are reserved in the certificate of incorporation to the shareholders. The
HUBCO Certificate does not reserve such power.

         The IBSF Certificate of  Incorporation  provides that IBSF's Bylaws may
be altered, amended or repealed by the affirmative vote of (1) two-thirds of the
whole Board of  Directors of IBSF and a majority of the  directors  unaffiliated
with  any  Related  Person,  or (2) the  holders  of not  less  than  80% of the
outstanding Voting Shares and an Independent Majority of Stockholders.

Limitations of Liability of Directors and Officers

         Under New Jersey law, a corporation  may include in its  certificate of
incorporation  a provision  which would,  subject to the  limitations  described
below, eliminate or limit a directors' or an officers' personal liability to the
corporation  or its  shareholders  for  monetary  damage for  breaches  of their
fiduciary  duty as a director  or  officer.  Under New Jersey law, a director or
officer  cannot be relieved  from  liability  or otherwise  indemnified  for any
breach of duty based upon an act or omission (i) in breach of such person's duty
of loyalty to the  corporation  or its  shareholders,  (ii) not in good faith or
involving  a knowing  violation  of law, or (iii)  resulting  in receipt by such
person of an improper  personal  benefit.  HUBCO's  Certificate of Incorporation
contains a provision  which  limits a director's  or officer's  liability to the
full extent permitted by New Jersey law.

         IBSF's  Certificate of Incorporation  contains a provision which limits
the liability of directors and officers of IBSF to the full extent  permitted by
New Jersey law.

Indemnification of Directors and Officers

         The NJBCA  provides  that a  corporation  has the power to  indemnify a
director,  officer,  employee or agent  ("Corporate  Agent")  against his or her
expenses  and  liabilities  in  connection  with any  proceeding  involving  the
Corporate Agent by reason of his or her being or having been a Corporate  Agent,
other  than a  proceeding  by or in the right of the  corporation,  if:  (i) the
Corporate  Agent was acting in good  faith and in a manner he or she  reasonably
believed to be in or not opposed to the best interests of the  corporation;  and
(ii)  with  respect  to any  criminal  proceeding,  the  Corporate  Agent had no
reasonable cause to believe that his or her conduct was unlawful.  A corporation
has the power to  indemnify a  Corporate  Agent  against his or her  expenses in
connection  with any proceeding by or in the right of the corporation to procure
a judgment in its favor which involves the Corporate Agent because he or she was
or is a  Corporate  Agent,  if he or she acted in good faith and in a manner the
Corporate  Agent  reasonably  believed  to be in or  not  opposed  to  the  best
interests of the corporation.

         HUBCO's   Certificate  of  Incorporation   provides  that  HUBCO  shall
indemnify  its  current and former  officers,  directors,  employees  and agents
against expenses  incurred in connection with any pending or threatened  action,
suit, or proceeding,  with respect to which the officer,  director,  employee or
agent is a  party,  or is  threatened  to be made a  party,  to the full  extent
permitted by the NJBCA.  HUBCO  maintains  directors'  and  officers'  liability
insurance on behalf of such persons.

         The  IBSF  Certificate  of  Incorporation   provides  that  IBSF  shall
indemnify  its  current and former  officers,  directors,  employees  and agents
against  expenses,  judgments,  fines,  taxes  and  amounts  paid in  settlement
incurred in connection with any threatened,  pending or completed action,  suit,
or proceeding, with respect to which the officer, director, employee or agent is
a party, or is threatened to be made party, to the full extent  permitted by the
NJBCA. The IBSF Certificate also provides for the advancement of expenses.  IBSF
maintains  directors'  and  officers'  liability  insurance  on  behalf  of such
persons.


                              SHAREHOLDER PROPOSALS

         The  Merger  may be  consummated  prior to the 1998  Annual  Meeting of
Shareholders of IBSF, in which event there would be no IBSF Annual  Meeting.  If
IBSF holds a 1998 Annual  Meeting of  Shareholders,  unless such 1998 meeting is
delayed,  any proposal which a IBSF  shareholder  wishes to have included in the
proxy materials of IBSF must have been presented to IBSF not later than March 5,
1998. No such proposal was received prior to such date.


                                  OTHER MATTERS

         Each proxy solicited hereby also confers discretionary authority on the
Board of Directors of IBSF to vote the proxy with respect to the approval of the
minutes of the last meeting of stockholders,  matters incident to the conduct of
the  meeting,  and upon such  other  matters  as may  properly  come  before the
Meeting.  Management  is not aware of any business that may properly come before
the Meeting  other than the  matters  described  above in this Proxy  Statement.
However,  if any other matters  should  properly come before the meeting,  it is
intended that the proxies  solicited  hereby will be voted with respect to those
other matters in accordance with the judgment of the persons voting the proxies.


                                  LEGAL OPINION

   

         Certain legal  matters  relating to the issuance of the shares of HUBCO

beneficially  owned 792 shares of HUBCO Common Stock as of June 2, 1998. Certain
legal  matters in  connection  with the Merger  will be passed  upon for IBSF by
Elias, Matz, Tiernan & Herrick L.L.P., counsel to IBSF.

                          AGREEMENT AND PLAN OF MERGER


                  THIS AGREEMENT AND PLAN OF MERGER,  dated as of March 31, 1998
("Agreement"),  is among HUBCO,  Inc.  ("HUBCO"),  a New Jersey  corporation and
registered bank holding company,  Hudson United Bank (the "Bank"),  a New Jersey
state-chartered  commercial banking  corporation and wholly-owned  subsidiary of
HUBCO, IBS Financial Corp., a New Jersey  corporation and registered savings and
loan holding company ("IBSF"),  and Inter-Boro  Savings and Loan Association,  a
New  Jersey  state-chartered  savings  and  loan  association  and  wholly-owned
subsidiary of IBSF (the "Association").

                                    RECITALS

                  The respective Boards of Directors of HUBCO and IBSF have each
determined  that it is in the  best  interests  of  HUBCO  and  IBSF  and  their
respective  shareholders for HUBCO to acquire IBSF by merging IBSF with and into
HUBCO with HUBCO  surviving and IBSF  shareholders  receiving the  consideration
hereinafter  set forth.  Immediately  after the merger of IBSF into  HUBCO,  the
Association shall be merged with and into the Bank with the Bank surviving.

                  The respective  Boards of Directors of IBSF,  HUBCO,  the Bank
and the  Association  have each duly adopted and approved this Agreement and the
Board  of  Directors  of IBSF  has  directed  that  it be  submitted  to  IBSF's
shareholders for approval.

                  As a condition for HUBCO to enter into this  Agreement,  HUBCO
has required that it receive an option on certain authorized but unissued shares
of IBSF Common  Stock (as  hereinafter  defined)  and,  simultaneously  with the
execution  of this  Agreement,  IBSF is issuing  an option to HUBCO (the  "HUBCO
Stock  Option") to purchase  certain  shares of the authorized and unissued IBSF
Common  Stock  subject to the terms and  conditions  set forth in the  Agreement
governing the HUBCO Stock Option.

                  NOW,  THEREFORE,  intending to be legally  bound,  the parties
hereto hereby agree as follows:

                             ARTICLE I - THE MERGER

                  1.1. The Merger.  Subject to the terms and  conditions of this
Agreement,  at the Effective Time (as hereafter  defined),  IBSF shall be merged
with and into HUBCO (the  "Merger") in accordance  with the New Jersey  Business
Corporation Act (the "NJBCA") and HUBCO shall be the surviving  corporation (the
"Surviving Corporation").

                  1.2.  Effect  of  the  Merger.  At  the  Effective  Time,  the
Surviving Corporation shall be considered the same business and corporate entity
as each of HUBCO  and IBSF  and  thereupon  and  thereafter,  all the  property,
rights,  privileges,  powers and franchises of each of HUBCO and IBSF shall vest
in the Surviving  Corporation and the Surviving  Corporation shall be subject to
and be deemed to have  assumed all of the debts,  liabilities,  obligations  and
duties  of each of HUBCO  and IBSF and shall  have  succeeded  to all of each of
their  relationships,  as fully  and to the  same  extent  as if such  property,
rights, privileges, powers, franchises, debts, liabilities,  obligations, duties
and relationships had been originally acquired,  incurred or entered into by the
Surviving Corporation. In addition, any reference to either of HUBCO and IBSF in
any contract or document,  whether executed or taking effect before or after the
Effective Time, shall be considered a reference to the Surviving  Corporation if
not inconsistent with the other provisions of the contract or document;  and any
pending action or other judicial  proceeding to which either of HUBCO or IBSF is
a party shall not be deemed to have abated or to have  discontinued by reason of
the Merger, but may be prosecuted to final judgment, order or decree in the same
manner as if the Merger had not been made; or the Surviving  Corporation  may be
substituted as a party to such action or proceeding,  and any judgment, order or
decree may be rendered  for or against it that might have been  rendered  for or
against either of HUBCO or IBSF if the Merger had not occurred.

                  1.3.  Certificate of Incorporation.  As of the Effective Time,
the  certificate  of   incorporation  of  HUBCO  shall  be  the  certificate  of
incorporation of the Surviving  Corporation  until otherwise amended as provided
by law.

                  1.4.  Bylaws.  As of the Effective  Time,  the Bylaws of HUBCO
shall be the Bylaws of the  Surviving  Corporation  until  otherwise  amended as
provided by law.

                  1.5.  Directors and Officers.  As of the Effective  Time,  the
directors  and  officers of HUBCO  shall be the  directors  and  officers of the
Surviving Corporation.

                  1.6 Closing,  Closing Date,  Determination  Date and Effective
Time.  Unless a different  date,  time and/or place are agreed to by the parties
hereto,  the  closing of the Merger  (the  "Closing")  shall take place at 10:00
a.m., at the offices of Pitney,  Hardin, Kipp & Szuch, 200 Campus Drive, Florham
Park, New Jersey,  on a date  determined by HUBCO on at least five business days
notice (the "Closing  Notice")  given to IBSF,  which date (the "Closing  Date")
shall be not less than  seven  nor more  than 10  business  days  following  the
receipt of all necessary regulatory,  governmental and shareholder approvals and
consents and the expiration of all statutory  waiting periods in respect thereof
and the  satisfaction or waiver of all of the conditions to the  consummation of
the  Merger  specified  in  Article  VI  hereof  (other  than  the  delivery  of
certificates,  opinions and other  instruments  and documents to be delivered at
the Closing).  In the Closing  Notice,  HUBCO shall  specify the  "Determination
Date" for purposes of determining the Median  Pre-Closing  Price (as hereinafter
defined),  which  date  shall be the  later of (i) the  first  date on which all
federal bank  regulatory  approvals (and waivers,  if applicable)  necessary for
consummation  of the Merger have been received and either party has notified the
other in writing that all such approvals (and waivers,  if applicable) have been
received,  or (ii) the date of the Shareholders Meeting (as such term is defined
in Section 5.7 hereof).  Simultaneous with or immediately following the Closing,
HUBCO and IBSF shall  cause to be filed a  certificate  of  merger,  in form and
substance  satisfactory  to HUBCO and IBSF,  with the  Secretary of State of the
State of New Jersey (the  "Certificate  of Merger").  The  Certificate of Merger
shall specify the "Effective Time" of the Merger,  which Effective Time shall be
a date and time  following  the Closing  agreed to by HUBCO and IBSF (which date
and time the parties  currently  anticipate will be the close of business on the
Closing Date). In the event the parties fail to specify the date and time in the
Certificate  of  Merger,  the  Merger  shall  become  effective  upon  (and  the
"Effective Time" shall be) the time of the filing of the Certificate of Merger.

                  1.7 The Bank Merger. Immediately following the Effective Time,
the Association  shall be then merged with and into the Bank (the "Bank Merger")
in  accordance  with the  provisions  of the New Jersey  Banking Act of 1948, as
amended (the "Banking Act"). In the Bank Merger, the Bank shall be the surviving
bank (the  "Surviving  Bank").  Upon the  consummation  of the Bank Merger,  the
separate  existence of the Association  shall cease and the Surviving Bank shall
be considered the same business and corporate  entity as each of the Association
and the Bank and all of the property, rights, privileges,  powers and franchises
of each of the Association and the Bank shall vest in the Surviving Bank and the
Surviving  Bank shall be deemed to have  assumed all of the debts,  liabilities,
obligations  and duties of each of the  Association  and the Bank and shall have
succeeded  to all or each of their  relationships,  fiduciary or  otherwise,  as
fully and to the same extent as if such property,  rights,  privileges,  powers,
franchises,  debts,  obligations,  duties and  relationships had been originally
acquired,  incurred or entered into by the Surviving Bank. Upon the consummation
of the Bank Merger,  the  certificate  of  incorporation  and Bylaws of the Bank
shall be the certificate of  incorporation  and Bylaws of the Surviving Bank and
the  officers and  directors of the Bank shall be the officers and  directors of
the  Surviving  Bank,  except as provided in Section 5.20 hereof.  Following the
execution of this  Agreement,  the  Association  and the Bank shall  execute and
deliver a merger  agreement  (the  "Bank  Merger  Agreement"),  both in form and
substance  reasonably  satisfactory to the parties hereto,  substantially as set
forth in Exhibit 1.7 hereto,  for delivery to the Commissioner of the New Jersey
Department of Banking and Insurance (the  "Department")  and the Federal Deposit
Insurance Corporation (the "FDIC") for approval of the Bank Merger.

                     ARTICLE II - CONVERSION OF IBSF SHARES

                  2.1.  Conversion  of IBSF Common  Stock.  Each share of common
stock,  par value $.01 per share,  of IBSF  ("IBSF  Common  Stock"),  issued and
outstanding immediately prior to the Effective Time (other than Excluded Shares,
as hereinafter defined) shall, by virtue of the Merger and without any action on
the part of the holder thereof, be converted as follows:

                           (a) Exchange of Common Stock; Exchange Ratio. Subject
to the  provisions  of this Section 2.1,  each share of IBSF Common Stock issued
and  outstanding  immediately  prior to the Effective  Time (other than Excluded
Shares) shall be converted at the Effective Time into the right to receive 0.534
shares (the "Exchange  Ratio") of Common Stock,  no par value,  of HUBCO ("HUBCO
Common Stock") subject to adjustment as provided in Section 2.1(c) or in Section
7.1(i)  and  subject  to the  payment  of cash in lieu of  fractional  shares in
accordance with Section 2.2(e).

                           (b)  Cancellation  of IBSF  Certificates.  After  the
Effective  Time, all such shares of IBSF Common Stock (other than those canceled
pursuant  to  Section   2.1(d))  shall  no  longer  be  outstanding   and  shall
automatically  be  canceled  and  retired  and shall  cease to  exist,  and each
certificate  previously  evidencing  any such shares (other than those  canceled
pursuant to Section 2.1(d)) shall thereafter  represent the right to receive the
Merger  Consideration  (as  defined  in  Section  2.2(b)).  The  holders of such
certificates  previously evidencing such shares of IBSF Common Stock outstanding
immediately  prior to the  Effective  Time shall  cease to have any rights  with
respect to such shares of IBSF Common Stock except as otherwise  provided herein
or by law. Such  certificates  previously  evidencing such shares of IBSF Common
Stock (other than those canceled  pursuant to Section 2.1(d)) shall be exchanged
for certificates evidencing shares of HUBCO Common Stock issued pursuant to this
Article II, upon the  surrender of such  certificates  in  accordance  with this
Article II. No fractional shares of HUBCO Common Stock shall be issued,  and, in
lieu thereof, a cash payment shall be made pursuant to Section 2.2(e).

                           (c) Capital  Changes.  If between the date hereof and
the Effective Time the outstanding  shares of HUBCO Common Stock shall have been
changed into a different number of shares or a different class, by reason of any
stock  dividend,  stock  split,  reclassification,   recapitalization,   merger,
combination  or exchange of shares,  the Exchange  Ratio and the  definition  of
Median Pre-Closing Price shall be correspondingly adjusted to reflect such stock
dividend, stock split, reclassification,  recapitalization,  merger, combination
or exchange of shares.

                           (d) Excluded Shares.  All shares of IBSF Common Stock
held by IBSF in its treasury or owned by HUBCO or by any of HUBCO's wholly-owned
subsidiaries  (other than shares held as trustee or in a fiduciary  capacity and
shares  held  as  collateral  on or in  lieu  of a debt  previously  contracted)
immediately prior to the Effective Time ("Excluded Shares") shall be canceled.


                  2.2.  Exchange of Certificates.

                  (a) Exchange  Agent.  As of the  Effective  Time,  HUBCO shall
deposit,  or  shall  cause to be  deposited,  with  Hudson  United  Bank,  Trust
Department or another bank or trust company  designated by HUBCO and  reasonably
acceptable  to IBSF (the  "Exchange  Agent"),  for the benefit of the holders of
shares of IBSF Common Stock,  for exchange in  accordance  with this Article II,
through the Exchange Agent, certificates evidencing shares of HUBCO Common Stock
and cash in such amount such that the Exchange  Agent  possesses  such number of
shares of HUBCO  Common Stock and such amount of cash as are required to provide
all of the  consideration  required  to be  exchanged  by HUBCO  pursuant to the
provisions  of this  Article II (such  certificates  for shares of HUBCO  Common
Stock,  together with any dividends or distributions  with respect thereto,  and
cash being hereinafter  referred to as the "Exchange Fund").  The Exchange Agent
shall, pursuant to irrevocable instructions,  deliver the HUBCO Common Stock and
cash out of the Exchange Fund in accordance with Sections 2.1 and 2.2(b). Except
as  contemplated  by Section 2.2(f) hereof,  the Exchange Fund shall not be used
for any other purpose.

                  (b) Exchange  Procedures.  As soon as  reasonably  practicable
either before or after the Effective  Time,  but in any event no later than five
business days after the Effective  Time,  HUBCO will instruct the Exchange Agent
to mail to  each  holder  of  record  of a  certificate  or  certificates  which
immediately  prior to the Effective  Time evidenced  outstanding  shares of IBSF
Common Stock (the  "Certificates"),  (i) a letter of  transmittal  (the form and
substance  of which is  reasonably  agreed  to by  HUBCO  and IBSF  prior to the
Effective Time and which shall specify that delivery shall be effected, and risk
of loss and title to the  Certificates  shall pass, only upon proper delivery of
the  Certificates  to the  Exchange  Agent  and  which  shall  have  such  other
provisions as HUBCO may reasonably  specify) and (ii) instructions for effecting
the surrender of the Certificates in exchange for certificates evidencing shares
of HUBCO Common Stock and cash in lieu of fractional shares. Upon surrender of a
Certificate for  cancellation to the Exchange Agent together with such letter of
transmittal,  duly  executed,  and  such  other  customary  documents  as may be
required pursuant to such instructions,  the holder of such Certificate shall be
entitled to receive in exchange therefor (x) certificates evidencing that number
of whole shares of HUBCO Common Stock which such holder has the right to receive
in  respect  of the  shares of IBSF  Common  Stock  formerly  evidenced  by such
Certificate  in  accordance  with Section 2.1 (as  adjusted  pursuant to Section
7.1(i) if applicable) and (y) cash in lieu of fractional  shares of HUBCO Common
Stock to which such  holder may be  entitled  pursuant  to Section  2.2(e)  (the
shares of HUBCO  Common  Stock and cash  described  in clauses (x) and (y) being
collectively referred to as the "Merger  Consideration") and the Certificates so
surrendered shall forthwith be canceled. In the event of a transfer of ownership
of shares of IBSF Common Stock which is not  registered in the transfer  records
of IBSF, a  certificate  evidencing  the proper number of shares of HUBCO Common
Stock and/or cash may be issued and/or paid in  accordance  with this Article II
to a transferee if the  Certificate  evidencing such shares of IBSF Common Stock
is presented to the Exchange  Agent,  accompanied  by all documents  required to
evidence and effect such  transfer  and by evidence  that any  applicable  stock
transfer taxes have been paid. Until surrendered as contemplated by this Section
2.2, each  Certificate  shall be deemed at any time after the Effective  Time to
evidence only the right to receive upon such surrender the Merger Consideration.

                  (c) Distributions  with Respect to Unexchanged Shares of HUBCO
Common  Stock.  No dividends or other  distributions  declared or made after the
Effective  Time with  respect to HUBCO Common Stock with a record date after the
Effective Time shall be paid to the holder of any unsurrendered Certificate with
respect to the shares of HUBCO Common Stock evidenced thereby, and no other part
of the Merger  Consideration shall be paid to any such holder,  until the holder
of such Certificate shall surrender such Certificate (or a suitable affidavit of
loss and customary bond).  Subject to the effect of applicable  laws,  following
surrender  of any such  Certificate,  there  shall be paid to the  holder of the
certificates  evidencing  shares  of  HUBCO  Common  Stock  issued  in  exchange
therefor, without interest, (i) promptly, the Merger Consideration to which such
holder is entitled  pursuant to Section  2.2(b) and the amount of  dividends  or
other  distributions  with  a  record  date  on  or  after  the  Effective  Time
theretofore  paid with respect to the shares of HUBCO Common Stock to which such
holder is entitled,  and (ii) at the  appropriate  payment  date,  the amount of
dividends or other  distributions,  with a record date on or after the Effective
Time but  prior to  surrender  and a payment  date  occurring  after  surrender,
payable with respect to such shares of HUBCO Common Stock.

                  (d) No  Further  Rights in IBSF  Common  Stock.  All shares of
HUBCO Common Stock  issued and cash paid upon  conversion  of the shares of IBSF
Common  Stock in  accordance  with the terms hereof shall be deemed to have been
issued or paid in full  satisfaction of all rights  pertaining to such shares of
IBSF Common Stock.

                  (e)  No  Fractional  Shares;   Median  Pre-Closing  Price.  No
certificates or scrip evidencing  fractional  shares of HUBCO Common Stock shall
be issued upon the surrender for exchange of  Certificates  and such  fractional
share interests will not entitle the owner thereof to vote or to any rights of a
shareholder of HUBCO.  Cash shall be paid in lieu of fractional  shares of HUBCO
Common Stock,  based upon the Median  Pre-Closing Price per whole share of HUBCO
Common Stock. The "Median  Pre-Closing  Price" shall be determined by taking the
price half-way between the Closing Prices left after discarding the 4 lowest and
4 highest Closing Prices in the 10 consecutive  trading day period which ends on
(and  includes)  the  Determination  Date.  The  "Closing  Price" shall mean the
closing  price of HUBCO  Common Stock as supplied by the Nasdaq Stock Market and
published in The Wall Street Journal. A "trading day" shall mean a day for which
a Closing Price is so supplied and published.  (The Nasdaq Stock Market, or such
other  national  securities  exchange on which HUBCO  Common Stock may be traded
after the date hereof, is referred to herein as "Nasdaq")

                  (f)  Termination of Exchange Fund. Any portion of the Exchange
Fund which  remains  undistributed  to the holders of IBSF Common  Stock for two
years after the Effective Time shall be delivered to HUBCO, upon demand, and any
holders of IBSF Common Stock who have not theretofore complied with this Article
II shall thereafter look only to HUBCO for the Merger  Consideration,  dividends
and distributions to which they are entitled.

                  (g) No  Liability.  Neither  HUBCO,  the Bank nor the Exchange
Agent shall be liable to any holder of shares of IBSF Common  Stock for any such
shares of HUBCO Common Stock or cash (or dividends or distributions with respect
thereto)  delivered to a public  official  pursuant to any applicable  abandoned
property, escheat or similar law.

                  (h) Withholding Rights.  HUBCO shall be entitled to deduct and
withhold,  or cause  the  Exchange  Agent to deduct  and  withhold,  from  funds
provided by the holder or from the  consideration  otherwise payable pursuant to
this Agreement to any holder of IBSF Common Stock,  the minimum amounts (if any)
that HUBCO is required to deduct and withhold with respect to the making of such
payment  under the Code (as defined in Section  3.8), or any provision of state,
local or foreign tax law.  To the extent that  amounts are so withheld by HUBCO,
such  withheld  amounts  shall be treated for all purposes of this  Agreement as
having  been paid to the  holder of IBSF  Common  Stock in respect of which such
deduction and withholding was made by HUBCO.

                  2.3. Stock Transfer  Books.  At the Effective  Time, the stock
transfer  books  of  IBSF  shall  be  closed  and  there  shall  be  no  further
registration  of  transfers  of shares of IBSF Common  Stock  thereafter  on the
records of IBSF. On or after the Effective Time, any  Certificates  presented to
the  Exchange  Agent or HUBCO for transfer  shall be  converted  into the Merger
Consideration.

                  2.4.  IBSF Stock  Options.  Other than the HUBCO Stock Option,
all options  which may be exercised  for issuance of IBSF Common Stock (each,  a
"Stock Option" and  collectively  the "Stock Options") are described in the IBSF
Disclosure  Schedule  and are issued and  outstanding  pursuant to the IBSF 1995
Stock Option Plan (the "IBSF Stock Option Plan") and the agreements  pursuant to
which such Stock Options were granted (each, an "Option Grant Agreement"). HUBCO
acknowledges  and agrees to honor the  provisions  of the IBSF Stock Option Plan
and the Option  Grant  Agreements,  including  those  relating  to  vesting  and
conversion  in  connection  with a change in control of IBSF.  Each Stock Option
outstanding at the Effective  Time (each, a "Continuing  Stock Option") shall be
converted into an option to purchase  HUBCO Common Stock,  wherein (i) the right
to purchase shares of IBSF Common Stock pursuant to the Continuing  Stock Option
shall be  converted  into the right to  purchase  that same  number of shares of
HUBCO Common Stock  multiplied by the Exchange  Ratio,  (ii) the option exercise
price per share of HUBCO  Common  Stock shall be the  previous  option  exercise
price per share of the IBSF Common  Stock  divided by the  Exchange  Ratio,  and
(iii) in all other  material  respects  the option  shall be subject to the same
terms and  conditions  as governed the  Continuing  Stock Option on which it was
based,  including  the length of time within  which the option may be  exercised
(which  shall not be  extended  except  that the  holder of a Stock  Option  who
continues in the service of HUBCO or a  subsidiary  of HUBCO shall not be deemed
to have  terminated  service for purposes of determining  the  Continuing  Stock
Option exercise period) and for all Continuing  Stock Options,  such adjustments
shall be and are  intended to be effected in a manner which is  consistent  with
Section  424(a) of the Code (as defined in Section 3.8 hereof).  Shares of HUBCO
Common Stock issuable upon exercise of Continuing Stock Options shall be covered
by an  effective  registration  statement  on Form S-8,  and HUBCO shall use its
reasonable  best efforts to file a  registration  statement on Form S-8 covering
such shares as soon as possible after the Effective Time.


              ARTICLE III - REPRESENTATIONS AND WARRANTIES OF IBSF

                  References herein to "IBSF Disclosure Schedule" shall mean all
of the disclosure  schedules  required by this Article III, dated as of the date
hereof and referenced to the specific sections and subsections of Article III of
this  Agreement,  which have been delivered on the date hereof by IBSF to HUBCO.
IBSF hereby represents and warrants to HUBCO as follows:

                  3.1.  Corporate Organization

                  (a) IBSF is a corporation  duly organized and validly existing
under  the laws of the State of New  Jersey.  IBSF has the  corporate  power and
authority to own or lease all of its  properties  and assets and to carry on its
business as it is now being  conducted,  and is duly licensed or qualified to do
business in each  jurisdiction in which the nature of the business  conducted by
it or the character or location of the  properties and assets owned or leased by
it makes such licensing or qualification necessary,  except where the failure to
be so  licensed or  qualified  would not have a material  adverse  effect on the
business,  operations,  assets  or  financial  condition  of IBSF  and the  IBSF
Subsidiaries  (as defined  below),  taken as a whole.  IBSF is  registered  as a
savings and loan  holding  company  under the Home  Owners' Loan Act, as amended
(the "HOLA").

                  (b) Each IBSF Subsidiary and its jurisdiction of incorporation
is listed in the IBSF Disclosure Schedule.  For purposes of this Agreement,  the
term "IBSF  Subsidiary"  means any  corporation,  partnership,  joint venture or
other legal entity in which IBSF,  directly or  indirectly,  owns at least a 50%
stock or other equity interest or for which IBSF,  directly or indirectly,  acts
as a general  partner,  provided that to the extent that any  representation  or
warranty  set forth  herein  covers a period  of time  prior to the date of this
Agreement,  the term "IBSF Subsidiary" shall include any entity which was a IBSF
Subsidiary  at any time  during such  period.  The  Association  is a New Jersey
state-chartered savings and loan association duly organized and validly existing
in stock form under the laws of the State of New Jersey.  All eligible  accounts
of depositors  issued by the Association are insured by the Savings  Association
Insurance Fund of the FDIC (the "SAIF") to the fullest extent  permitted by law.
Each IBSF  Subsidiary has the corporate  power and authority to own or lease all
of its  properties  and assets and to carry on its  business  as it is now being
conducted and is duly licensed or qualified to do business in each  jurisdiction
in which the nature of the business conducted by it or the character or location
of the  properties  and  assets  owned or leased by it makes such  licensing  or
qualification necessary, except where the failure to be so licensed or qualified
would not have a material adverse effect on the business,  operations, assets or
financial condition of IBSF and the IBSF Subsidiaries, taken as a whole.

                  (c) The IBSF Disclosure  Schedule sets forth true and complete
copies of the Certificate of Incorporation  and Bylaws, as in effect on the date
hereof,  of IBSF and each IBSF  Subsidiary.  Except  as set forth in  Disclosure
Schedule  3.1(b),  the Association  and IBSF do not own or control,  directly or
indirectly,  any  equity  interest  in any  corporation,  company,  association,
partnership, joint venture or other entity.

                  3.2.  Capitalization.  The  authorized  capital  stock of IBSF
consists of 25,000,000  shares of IBSF Common Stock. As of March 27, 1998, there
were  10,959,674  shares of IBSF Common Stock issued and outstanding and 650,049
treasury  shares.  As of March 27,  1998,  there were  1,275,503  shares of IBSF
Common Stock  issuable  upon exercise of  outstanding  stock  options.  The IBSF
Disclosure  Schedule  contains  (i) a list of all Stock  Options,  their  strike
prices and expiration dates, and (ii) true and complete copies of the IBSF Stock
Option Plan and a specimen of each form of Option  Grant  Agreement  pursuant to
which  any  outstanding  Stock  Option  was  granted,  including  a list of each
outstanding  Stock Option  issued  pursuant  thereto.  All Stock Options will be
fully vested on the Closing Date,  in each case in accordance  with the terms of
the IBSF Stock  Option Plan and Option Grant  Agreements  pursuant to which such
Stock Options were  granted.  All issued and  outstanding  shares of IBSF Common
Stock,  and all issued  and  outstanding  shares of  capital  stock of each IBSF
Subsidiary,  have been duly  authorized  and  validly  issued,  are fully  paid,
nonassessable and free of preemptive rights and are free and clear of any liens,
encumbrances,  charges,  restrictions or rights of third parties imposed by IBSF
or any  IBSF  Subsidiary.  Except  for the  Stock  Options  listed  on the  IBSF
Disclosure Schedule and the HUBCO Stock Option, neither IBSF nor the Association
has granted nor is bound by any outstanding  subscriptions,  options,  warrants,
calls,  commitments  or agreements  of any  character  calling for the transfer,

Association or any securities  representing the right to purchase,  subscribe or
otherwise receive any shares of such capital stock or any securities convertible
into any such shares, and there are no agreements or understandings with respect
to voting of any such shares.

                  (a)  Subject  to  the  approval  of  this  Agreement  and  the

This Agreement has been duly and validly  executed and delivered by IBSF and the
Association,  and constitutes a valid and binding obligation of each of IBSF and
the Association, enforceable against IBSF and the Association in accordance with
its  terms,  except  to  the  extent  that  enforcement  may be  limited  by (i)
bankruptcy,    insolvency,    reorganization,    moratorium,    conservatorship,
receivership  or other  similar laws now or  hereafter in effect  relating to or
affecting  the  enforcement  of  creditors'  rights  generally  or the rights of
creditors of New Jersey  state-chartered  savings and loan associations or their
holding companies, (ii) general equitable principles, and (iii) laws relating to
the safety and soundness of insured  depository  institutions and except that no
representation is made as to the effect or availability of equitable remedies or
injunctive relief.

                  (b) Neither the  execution  and delivery of this  Agreement by
IBSF or the Association,  nor the consummation by IBSF or the Association of the
transactions  contemplated  hereby  in  accordance  with the  terms  hereof,  or
compliance  by IBSF or the  Association  with  any of the  terms  or  provisions
hereof,   will  (i)  violate  any  provision  of  IBSF's  or  the  Association's
Certificate  of  Incorporation  or Bylaws,  (ii)  assuming that the consents and
approvals  set  forth  below  are duly  obtained,  violate  any  statute,  code,
ordinance,  rule,  regulation,  judgment,  order,  writ,  decree  or  injunction

assets, or (iii) except as set forth in the IBSF Disclosure  Schedule,  violate,
conflict with, result in a breach of any provisions of, constitute a default (or
an event  which,  with  notice or lapse of time,  or both,  would  constitute  a
default)  under,  result  in the  termination  of,  accelerate  the  performance
required by, or result in the creation of any lien, security interest, charge or
other encumbrance upon any of the respective properties or assets of IBSF or the
Association under, any of the terms, conditions or provisions of any note, bond,
mortgage,   indenture,  deed  of  trust,  license,  lease,  agreement  or  other
instrument  or  obligation to which IBSF or the  Association  is a party,  or by
which  they or any of their  respective  properties  or  assets  may be bound or
affected except,  with respect to (ii) and (iii) above,  such as individually or
in the  aggregate  will not have a  material  adverse  effect  on the  business,
operations,  assets or financial  condition  of IBSF and the IBSF  Subsidiaries,
taken  as  a  whole,  and  which  will  not  prevent  or  materially  delay  the
consummation of the transactions  contemplated  hereby.  Except for consents and
approvals  of or  filings  or  registrations  with or  notices  to the  Board of
Governors of the Federal  Reserve  System (the "FRB"),  the FDIC,  the Office of
Thrift  Supervision (the "OTS"),  the Department,  the New Jersey  Department of
Environmental  Protection (the "DEP") (if required), the Securities and Exchange
Commission (the "SEC"),  and the  shareholders of IBSF, no consents or approvals
of or filings or registrations  with or notices to any third party or any public
body or  authority  are  necessary  on  behalf  of IBSF  or the  Association  in
connection with (x) the execution and delivery by IBSF of this Agreement and (y)
the  consummation  by IBSF of the Merger,  and the  consummation by IBSF and the
Association of the other transactions  contemplated  hereby,  except (i) such as
are listed in the IBSF  Disclosure  Schedule and (ii) such as individually or in
the aggregate will not (if not obtained)  have a material  adverse effect on the
business,  operations,  assets  or  financial  condition  of IBSF  and the  IBSF
Subsidiaries taken as a whole or prevent or materially delay the consummation of
the transactions  contemplated hereby. To the best of IBSF's knowledge,  no fact
or  condition  exists  which IBSF has reason to believe  will prevent it and the
Association from obtaining the aforementioned consents and approvals.

                  3.4.  Financial Statements.

                  (a) The IBSF  Disclosure  Schedule  sets  forth  copies of the
consolidated  statements of financial condition of IBSF as of September 30, 1996
and  1997,  and the  related  consolidated  statements  of  income,  changes  in
stockholders'  equity and of cash flows for the periods  ended  September 30, in
each of the three fiscal years 1995 through  1997, in each case  accompanied  by
the audit report of Deloitte & Touche LLP,  independent  public accountants with
respect to IBSF ("D&T"), and the unaudited  consolidated  statement of condition
of  IBSF  as of  December  31,  1997  and  the  related  unaudited  consolidated
statements of income and cash flows for the three months ended December 31, 1997
and 1996, as reported in IBSF's  Quarterly  Report on Form 10-Q,  filed with the
SEC  under  the  Securities  Exchange  Act of  1934,  as  amended  ("1934  Act")
(collectively,  the "IBSF Financial Statements").  The IBSF Financial Statements
(including  the related  notes) have been prepared in accordance  with generally
accepted accounting  principles ("GAAP") consistently applied during the periods
involved  (except  as may be  indicated  therein or in the notes  thereto),  and
fairly present the consolidated financial condition of IBSF as of the respective
dates set forth  therein,  and the related  consolidated  statements  of income,
changes in stockholders' equity and cash flows fairly present the results of the
consolidated operations,  changes in shareholders' equity and cash flows of IBSF
for the respective periods set forth therein.

                  (b) The books and records of IBSF and each of its Subsidiaries
are being maintained in material compliance with applicable legal and accounting
requirements.

                  (c)  Except  as and  to the  extent  reflected,  disclosed  or
reserved against in the IBSF Financial Statements (including the notes thereto),
as of  December  31,  1997,  neither  IBSF  nor  any  IBSF  Subsidiary  had  any
liabilities, whether absolute, accrued, contingent or otherwise, material to the
business,  operations,  assets  or  financial  condition  of IBSF  and the  IBSF
Subsidiaries,  taken  as a whole  which  were  required  by  GAAP  (consistently
applied) to be  disclosed  in IBSF's  consolidated  statement of condition as of
December 31, 1997 or the notes thereto.  Since  December 31, 1997,  neither IBSF
nor any IBSF  Subsidiary  has  incurred any  liabilities  except in the ordinary
course of business and  consistent  with prudent  business  practice,  except as
related to the  transactions  contemplated  by this  Agreement  or except as set
forth in the IBSF Disclosure Schedule.

                  3.5.  Broker's  and Other Fees.  Except for Ryan,  Beck & Co.,
Inc. ("Ryan,  Beck"),  neither IBSF nor any of its Subsidiaries nor any of their
respective  directors  or officers has employed any broker or finder or incurred
any  liability for any broker's or finder's  fees or  commissions  in connection
with any of the transactions  contemplated by this Agreement. The agreement with
Ryan, Beck is set forth in the IBSF Disclosure Schedule.  Other than pursuant to
the agreement with Ryan, Beck, there are no fees (other than time charges billed
at usual and customary rates) payable to any consultants,  including lawyers and
accountants,  in connection with this transaction or which would be triggered by
consummation  of this  transaction  or the  termination  of the services of such
consultants by IBSF or any its Subsidiaries.

                  3.6.  Absence of Certain Changes or Events.

                  (a) Except as disclosed in the IBSF Disclosure Schedule, there
has not been any IBSF Material  Adverse  Change (as  hereinafter  defined) since
December  31,  1997 and to the best of IBSF's  knowledge,  no fact or  condition
exists which IBSF believes will cause such an IBSF  Material  Adverse  Change in
the future.  "IBSF Material  Adverse  Change" means any change which is material
and adverse to the  consolidated  financial  condition,  results of  operations,
business  or assets of IBSF and the IBSF  Subsidiaries  taken as a whole,  other
than (i) a change in the value of the respective  investment and loan portfolios
of IBSF and the IBSF  Subsidiaries  as the result of a change in interest  rates
generally, (ii) a change occurring after the date hereof in any federal or state
law, rule or regulation or in GAAP,  which change affects  savings  institutions
generally,  (iii) reasonable expenses incurred in connection with this Agreement
and the transactions contemplated hereby, (iv) payments to executive officers or
other  employees  of  IBSF  or  the   Association   pursuant  to  agreements  or
arrangements with such persons, which agreements or arrangements are included in
the IBSF  Disclosure  Schedule,  or (v) actions or omissions of IBSF or any IBSF
Subsidiary  either  specifically  permitted by this  Agreement or taken with the
prior written consent of HUBCO in contemplation of the transactions contemplated
hereby  (including   without  limitation  any  actions  taken  by  IBSF  or  the
Association pursuant to Section 5.15 of this Agreement).

                  (b)  Except  as set  forth  in the IBSF  Disclosure  Schedule,
neither IBSF nor any IBSF  Subsidiary  has taken or permitted any of the actions
set forth in Section 5.2 hereof  between  December  31, 1997 and the date hereof
and,  except  for  execution  of  this   Agreement,   and  the  other  documents
contemplated   hereby,  IBSF  and  each  IBSF  Subsidiary  has  conducted  their
respective  businesses  only  in  the  ordinary  course,  consistent  with  past
practice.

                  3.7.  Legal  Proceedings.  Except  as  disclosed  in the  IBSF
Disclosure  Schedule,  and except for ordinary routine litigation  incidental to
the  business  of IBSF  and the  IBSF  Subsidiaries,  neither  IBSF nor any IBSF
Subsidiary is a party to any, and there are no pending or, to the best of IBSF's
knowledge,  threatened  legal,  administrative,  arbitral or other  proceedings,
claims, actions or governmental investigations of any nature against IBSF or any
IBSF Subsidiary which, if decided adversely to IBSF or any IBSF Subsidiary,  are
reasonably likely to have a material adverse effect on the business, operations,
assets  or  financial  condition  of IBSF and the IBSF  Subsidiaries  taken as a
whole. Except as disclosed in the IBSF Disclosure Schedule, neither IBSF nor any
IBSF  Subsidiary  is a party to any  order,  judgment  or decree  entered in any
lawsuit or proceeding which is material to IBSF or such IBSF Subsidiary.

                  3.8.  Taxes and Tax Returns.

                  (a) IBSF and each IBSF  Subsidiary  has duly  filed (and until
the Effective Time will so file) all returns, declarations, reports, information
returns and statements  ("Returns")  required to be filed by it on or before the
Effective  Time in  respect of any  federal,  state and local  taxes  (including
withholding taxes,  penalties or other payments required) and has duly paid (and
until the Effective Time will so pay) all such taxes due and payable, other than
taxes or other charges which are being contested in good faith (and disclosed to
HUBCO in writing) or against which reserves have been established. IBSF and each
IBSF Subsidiary has established (and until the Effective Time will establish) on
its books and records reserves that are adequate for the payment of all federal,
state and local taxes not yet due and  payable,  but are  incurred in respect of
IBSF or such IBSF  Subsidiary  through  such date.  None of the federal or state
income tax  returns of IBSF or any IBSF  Subsidiary  have been  examined  by the
Internal  Revenue  Service  (the  "IRS") or the New Jersey  Division of Taxation
within the past six years. To the best knowledge of IBSF, except as disclosed in
the IBSF Disclosure  Schedule,  there are no audits or other  administrative  or
court proceedings  presently pending nor any other disputes pending with respect
to,  or  claims  asserted  for,  taxes  or  assessments  upon  IBSF or any  IBSF
Subsidiary,  nor has IBSF or any IBSF Subsidiary given any currently outstanding
waivers or  comparable  consents  regarding  the  application  of the statute of
limitations with respect to any taxes or Returns.

                  (b) Neither IBSF nor any IBSF Subsidiary (i) has requested any
extension  of time within  which to file any Return  which  Return has not since
been filed,  (ii) is a party to any agreement  providing  for the  allocation or
sharing of taxes except as disclosed in the IBSF Disclosure  Schedule,  (iii) is
required to include in income any  adjustment  pursuant to Section 481(a) of the
Internal Revenue Code of 1986, as amended (the "Code"), by reason of a voluntary
change in accounting  method initiated by IBSF or such IBSF Subsidiary (nor does
IBSF have any knowledge that the IRS has proposed any such  adjustment or change
of accounting method), or (iv) has filed a consent pursuant to Section 341(f) of
the Code or agreed to have Section 341(f)(2) of the Code apply.

                  (c)  Neither  IBSF  nor any IBSF  Subsidiary  has any tax loss
carryforwards.

                  3.9.  Employee Benefit Plans.

                  (a)  Except  as set  forth  on the IBSF  Disclosure  Schedule,
neither IBSF nor any IBSF  Subsidiary  maintains or contributes to any "employee
pension benefit plan" (the "IBSF Pension Plans") within the meaning of such term
in Section  3(2)(A) of the Employee  Retirement  Income Security Act of 1974, as
amended  ("ERISA"),  "employee  welfare benefit plan" (the "IBSF Welfare Plans")
within the meaning of such term in Section  3(1) of ERISA,  stock  option  plan,
stock purchase plan,  deferred  compensation  plan,  severance plan, bonus plan,
employment agreement, director retirement program or other similar plan, program
or  arrangement.  Neither IBSF nor any IBSF  Subsidiary  has, since September 2,
1974,  contributed  to any  "Multiemployer  Plan," within the meaning of Section
3(37) of ERISA.

                  (b) IBSF has  previously  delivered to HUBCO,  and included in
the IBSF  Disclosure  Schedule,  a  complete  and  accurate  copy of each of the
following with respect to each of the IBSF Pension Plans and IBSF Welfare Plans,
if any: (i) plan  document,  summary plan  description,  and summary of material
modifications (if not available, a detailed description of the foregoing);  (ii)
trust  agreement  or  insurance   contract,   if  any;  (iii)  most  recent  IRS
determination letter, if any; (iv) most recent actuarial report, if any; and (v)
most recent annual report on Form 5500.

                  (c) The present value of all accrued benefits, both vested and
non-vested,  under each of the IBSF Pension  Plans subject to Title IV of ERISA,
based upon the  actuarial  assumptions  used for  funding  purposes  in the most
recent actuarial valuation prepared by such IBSF Pension Plan's actuary, did not
exceed the then  current  value of the assets of such  plans  allocable  to such
accrued  benefits.  To the best of IBSF's knowledge,  the actuarial  assumptions
then  utilized for such plans were  reasonable  and  appropriate  as of the last
valuation date and reflect then current market conditions.

                  (d) During the last six years,  the Pension  Benefit  Guaranty
Corporation  ("PBGC") has not asserted any claim for  liability  against IBSF or
any IBSF Subsidiary which has not been paid in full.

                  (e) All premiums (and interest  charges and penalties for late
payment,  if applicable)  due to the PBGC with respect to each IBSF Pension Plan
have been paid. All contributions  required to be made to each IBSF Pension Plan
under the terms  thereof,  ERISA or other  applicable law have been timely made,
and all amounts  properly  accrued to date as liabilities of IBSF which have not
been paid have been properly recorded on the books of IBSF.

                  (f) Except as disclosed in the IBSF Disclosure Schedule,  each
of the IBSF Pension Plans,  IBSF Welfare Plans and each other  employee  benefit
plan  and  arrangement  identified  on the  IBSF  Disclosure  Schedule  has been
operated in  compliance in all material  respects with the  provisions of ERISA,
the Code,  all  regulations,  rulings and  announcements  promulgated  or issued
thereunder,   and  all  other  applicable  governmental  laws  and  regulations.
Furthermore,  except  as  disclosed  in the IBSF  Disclosure  Schedule,  if IBSF
maintains  any IBSF Pension  Plan,  IBSF has received or applied for a favorable
determination letter from the IRS which takes into account the Tax Reform Act of
1986  and  (to  the  extent  it  mandates  currently  applicable   requirements)
subsequent legislation,  and IBSF is not aware of any fact or circumstance which
would disqualify any plan.

                  (g) To the best  knowledge of IBSF, no  non-exempt  prohibited
transaction,  within the  meaning of Section  4975 of the Code or Section 406 of
ERISA,  has occurred  with respect to any IBSF Welfare Plan or IBSF Pension Plan
that  would  result  in any  material  tax  or  penalty  for  IBSF  or any  IBSF
Subsidiary.

                  (h) No IBSF Pension Plan or any trust created  thereunder  has
been  terminated,  nor have there been any "reportable  events" (notice of which
has not been  waived by the  PBGC),  within the  meaning  of Section  4034(b) of
ERISA, with respect to any IBSF Pension Plan.

                  (i) No "accumulated funding deficiency," within the meaning of
Section 412 of the Code,  has been  incurred  with  respect to any IBSF  Pension
Plan.

                  (j) There are no material  pending,  or, to the best knowledge
of IBSF,  material  threatened or anticipated  claims (other than routine claims
for  benefits) by, on behalf of, or against any of the IBSF Pension Plans or the
IBSF  Welfare  Plans,  any  trusts  created  thereunder  or any  other  plan  or
arrangement identified in the IBSF Disclosure Schedule.

                  (k) Except as disclosed in the IBSF  Disclosure  Schedule,  no
IBSF  Pension  Plan or IBSF  Welfare  Plan  provides  medical or death  benefits
(whether or not insured) beyond an employee's retirement or other termination of
service,  other than (i) coverage  mandated by law or pursuant to  conversion or
continuation  rights  set out in  such  Plan or an  insurance  policy  providing
benefits thereunder, or (ii) death benefits under any IBSF Pension Plan.

                  (l)  Except  with  respect  to  customary  health,   life  and
disability  benefits,  there are no unfunded benefit  obligations  which are not
accounted for by reserves shown on the IBSF Financial Statements and established
in accordance with GAAP.

                  (m) With  respect to each IBSF  Pension  Plan and IBSF Welfare
Plan that is funded wholly or partially through an insurance policy,  there will
be no liability of IBSF or any IBSF  Subsidiary as of the  Effective  Time under
any such insurance policy or ancillary  agreement with respect to such insurance
policy in the nature of a retroactive rate adjustment,  loss sharing arrangement
or other actual or  contingent  liability  arising  wholly or  partially  out of
events occurring prior to the Effective Time.

                  (n) Except (i) for payments and other benefits due pursuant to
the employment agreements included within the IBSF Disclosure Schedule, and (ii)
as set forth in the IBSF Disclosure Schedule, or as expressly agreed to by HUBCO
in writing  either  pursuant to this  Agreement or otherwise,  or as required by
law, the  consummation of the  transactions  contemplated by this Agreement will
not (x) entitle any current or former employee of IBSF or any IBSF Subsidiary to
severance  pay,  unemployment  compensation  or  any  similar  payment,  or  (y)
accelerate  the time of  payment  or  vesting,  or  increase  the  amount of any
compensation  or benefits due to any current or former  employee  under any IBSF
Pension Plan or IBSF Welfare Plan.

                  (o) Except  for the IBSF  Pension  Plans and the IBSF  Welfare
Plans,  and  except as set forth on the IBSF  Disclosure  Schedule,  IBSF has no
deferred compensation agreements,  understandings or obligations for payments or
benefits to any current or former  director,  officer or employee of IBSF or any
IBSF Subsidiary or any predecessor of any thereof.  The IBSF Disclosure Schedule
sets forth:  (i) true and complete copies of the agreements,  understandings  or
obligations  with  respect to each such current or former  director,  officer or
employee, and (ii) the most recent actuarial or other calculation of the present
value of such payments or benefits.

                  (p) Except as set forth in the IBSF Disclosure Schedule,  IBSF
does not maintain or otherwise pay for life insurance policies (other than group
term life  policies  on  employees)  with  respect to any  director,  officer or
employee.  The IBSF  Disclosure  Schedule lists each such  insurance  policy and
includes  a copy of each  agreement  with a party  other than the  insurer  with
respect to the payment,  funding or  assignment  of such policy.  To the best of
IBSF `s  knowledge,  neither IBSF nor any IBSF Pension Plan or IBSF Welfare Plan
owns any individual or group  insurance  policies issued by an insurer which has
been  found  to be  insolvent  or  is  in  rehabilitation  pursuant  to a  state
proceeding.

                  (q) Except as set forth in the IBSF Disclosure Schedule,  IBSF
does not maintain any retirement plan or retiree medical plan or arrangement for
directors.  The IBSF Disclosure  Schedule sets forth the complete  documentation
and actuarial evaluation of any such plan.

                  3.10.  Reports.

                  (a) The IBSF  Disclosure  Schedule  lists,  and as to item (i)
below IBSF has previously  delivered to HUBCO a complete copy of, each (i) final
registration  statement,  prospectus,  annual,  quarterly or current  report and
definitive  proxy  statement filed by IBSF since January 1, 1996 pursuant to the
Securities  Act of  1933,  as  amended  ("1933  Act"),  or the 1934 Act and (ii)
communication  (other than general  advertising  materials  and press  releases)
mailed by IBSF to its  shareholders  as a class since January 1, 1996,  and each
such  communication,  as of its date, complied in all material respects with all
applicable  statutes,  rules and  regulations  and did not  contain  any  untrue
statement of a material  fact or omit to state any material  fact required to be
stated  therein or necessary in order to make the  statements  made therein,  in
light of the circumstances under which they were made, not misleading;  provided
that information as of a later date shall be deemed to modify  information as of
an earlier date..

                  (b) Since January 1, 1996, (i) IBSF has filed all reports that
it was  required to file with the SEC under the 1934 Act,  and (ii) IBSF and the
Association each has duly filed all material forms,  reports and documents which
it was required to file with each agency  charged with  regulating any aspect of
its business,  in each case in form which was correct in all material  respects,
and, subject to permission from such regulatory authorities,  IBSF promptly will
deliver or make available to HUBCO accurate and complete copies of such reports.
As of their respective dates, each such form, report, or document, and each such
final registration statement,  prospectus,  annual, quarterly or current report,
definitive proxy statement or  communication,  complied in all material respects
with all  applicable  statutes,  rules and  regulations  and did not contain any
untrue  statement of a material fact or omit to state any material fact required
to be stated therein or necessary in order to make the statements  made therein,
in light of the  circumstances  under  which  they were  made,  not  misleading;
provided  that  information  contained  in any such  document as of a later date
shall be deemed to modify information as of an earlier date. The IBSF Disclosure
Schedule  lists  the  dates  of all  examinations  of  IBSF  or the  Association
conducted  by either the FDIC or the OTS since  January 1, 1996 and the dates of
any responses thereto submitted by IBSF or the Association.

                  3.11.  IBSF  and  Association  Information.   The  information
relating  to IBSF and the  Association,  this  Agreement,  and the  transactions
contemplated  hereby  (except for  information  relating  solely to HUBCO) to be
contained  in the Proxy  Statement-Prospectus  (as  defined  in  Section  5.6(a)
hereof)  to be  delivered  to  shareholders  of  IBSF  in  connection  with  the
solicitation  of  their  approval  of the  Merger,  as of  the  date  the  Proxy
Statement-Prospectus  is mailed to shareholders of IBSF, and up to and including
the date of the meeting of shareholders to which such Proxy Statement-Prospectus
relates,  will not contain any untrue  statement  of a material  fact or omit to
state a material  fact  required to be stated  therein or  necessary to make the
statements  therein,  in light of the circumstances  under which they were made,
not misleading.

                  3.12.  Compliance  with Applicable Law. Except as set forth in
the IBSF Disclosure Schedule,  IBSF and each IBSF Subsidiary holds all licenses,
franchises,  permits and authorizations  necessary for the lawful conduct of its
business  and has complied  with and is not in default in any respect  under any
applicable law, statute, order, rule, regulation, policy and/or guideline of any
federal,  state or local  governmental  authority  relating to IBSF or such IBSF
Subsidiary (including, without limitation,  consumer, community and fair lending
laws)  (other  than where the  failure to have a license,  franchise,  permit or
authorization  or where  such  default  or  noncompliance  will not  result in a
material  adverse  effect  on the  business,  operations,  assets  or  financial
condition of IBSF and the IBSF  Subsidiaries  taken as a whole) and IBSF has not
received  notice of violation of, and does not know of any violations of, any of
the above.

not have a  material  adverse  effect  on the  business,  operations,  assets or
financial condition of IBSF and the IBSF Subsidiaries, taken as a whole.

                  3.14.  Properties and Insurance.

                  (a) Except as set forth in the IBSF Disclosure Schedule,  IBSF

to all material  assets and  properties,  whether real or personal,  tangible or

course of business since December 31, 1997), subject to no encumbrances,  liens,
mortgages,  security  interests  or pledges,  except (i) those items that secure

respect to owned  real  property,  title  imperfections  noted in title  reports
delivered  to  HUBCO  prior  to the  date  hereof.  Except  as  affected  by the
transactions  contemplated  hereby,  IBSF or one or more of its  Subsidiaries as
lessees have the right under valid and subsisting leases to occupy, use, possess
and  control  all real  property  leased  by IBSF and such  Subsidiaries  in all
material respects as presently occupied,  used, possessed and controlled by IBSF
and its Subsidiaries.

                  (b) Except as set forth in the IBSF Disclosure  Schedule,  the
business  operations  and all insurable  properties  and assets of IBSF and each
IBSF  Subsidiary are insured for their benefit  against all risks which,  in the
reasonable  judgment of the management of IBSF,  should be insured  against,  in
each  case  under   policies  or  bonds   issued  by   insurers  of   recognized
responsibility, in such amounts with such deductibles and against such risks and
losses as are in the opinion of the management of IBSF adequate for the business
engaged in by IBSF and the IBSF  Subsidiaries.  As of the date  hereof,  neither
IBSF nor any IBSF  Subsidiary has received any notice of  cancellation or notice
of a material  amendment of any such  insurance  policy or bond or is in default
under any such policy or bond, no coverage  thereunder is being disputed and all
material  claims  thereunder  have  been  filed  in a timely  fashion.  The IBSF
Disclosure  Schedule sets forth in summary form a list of all insurance policies
of IBSF and the IBSF Subsidiaries.

                  3.15.  Minute  Books.  The  minute  books of IBSF and the IBSF
Subsidiaries  contain records of all meetings and other corporate action held of
their respective  shareholders and Boards of Directors (including  committees of
their  respective  Boards of  Directors)  that are  complete and accurate in all
material respects.

                  3.16.  Environmental Matters.  Except as set forth in the IBSF
Disclosure Schedule:

                  (a) Neither  IBSF nor any IBSF  Subsidiary  has  received  any
written notice, citation,  claim, assessment,  proposed assessment or demand for
abatement  alleging that IBSF or such IBSF Subsidiary  (either  directly or as a
trustee or  fiduciary,  or as a  successor-in-interest  in  connection  with the
enforcement of remedies to realize the value of properties serving as collateral
for  outstanding  loans) is  responsible  for the  correction  or cleanup of any
condition   resulting  from  the  violation  of  any  law,  ordinance  or  other
governmental  regulation regarding  environmental  matters,  which correction or
cleanup  would be  material to the  business,  operations,  assets or  financial
condition  of IBSF and the  IBSF  Subsidiaries  taken  as a  whole.  IBSF has no
knowledge that any toxic or hazardous substances or materials have been emitted,
generated, disposed of or stored on any real property owned or leased by IBSF or
any IBSF Subsidiary, as OREO or otherwise, or owned or controlled by IBSF or any
IBSF Subsidiary as a trustee or fiduciary (collectively,  "Properties"),  in any
manner that  violates  any  presently  existing  federal,  state or local law or
regulation  governing  or  pertaining  to such  substances  and  materials,  the
violation  of which  would  have a  material  adverse  effect  on the  business,
operations,  assets or financial  condition  of IBSF and the IBSF  Subsidiaries,
taken as a whole. Except as described in the IBSF Disclosure  Schedule,  none of
the  Properties  is  located  in  the  State  of New  Jersey  or  the  State  of
Connecticut.

                  (b) IBSF has no knowledge  that any of the Properties has been
operated in any manner in the three  years  prior to the date of this  Agreement
that violated any applicable federal, state or local law or regulation governing
or pertaining to toxic or hazardous  substances and materials,  the violation of
which would have a material adverse effect on the business,  operations,  assets
or financial condition of IBSF and the IBSF Subsidiaries taken as a whole.

                  (c)  To  the  best  of  IBSF's  knowledge,   IBSF,  each  IBSF
Subsidiary  and any and all of their  tenants or  subtenants  have all necessary
permits  and have  filed all  necessary  registrations  material  to permit  the
operation of the  Properties in the manner in which the operations are currently
conducted  under all  applicable  federal,  state or local  environmental  laws,
excepting  only those permits and  registrations  the absence of which would not
have a material  adverse effect upon the  operations  that require the permit or
registration.

                  (d) To the knowledge of IBSF, there are no underground storage
tanks on, in or under any of the  Properties  and no  underground  storage tanks
have been closed or removed  from any of the  Properties  while the property was
owned, operated or controlled by IBSF or any IBSF Subsidiary.

                  3.17.  Reserves.  As of December 31, 1997,  the  allowance for
loan  losses in the IBSF  Financial  Statements  was  adequate  pursuant to GAAP
(consistently  applied),  and the  methodology  used to  compute  the loan  loss
reserve complies in all material respects with GAAP  (consistently  applied) and
all  applicable  policies of the OTS. As of December 31,  1997,  the reserve for
OREO properties (or if no reserve, the carrying value of OREO properties) in the
IBSF Financial Statements was adequate pursuant to GAAP (consistently  applied),
and the  methodology  used to compute the reserve for OREO  properties (or if no
reserve,  the  carrying  value  of OREO  properties)  complies  in all  material
respects with GAAP  (consistently  applied) and all  applicable  policies of the
OTS.

                  3.18. No Parachute  Payments.  Except as set forth in the IBSF
Disclosure Schedule, no officer, director, employee or agent (or former officer,
director,  employee or agent) of IBSF or any IBSF Subsidiary is entitled now, or
will or may be entitled to as a consequence of this Agreement or the Merger,  to
any  payment  or  benefit  from  IBSF,  a IBSF  Subsidiary,  HUBCO or any  HUBCO
Subsidiary  which if paid or  provided  would  constitute  an "excess  parachute
payment",  as  defined in Section  280G of the Code or  regulations  promulgated
thereunder.

                  3.19.  Agreements with Bank  Regulators.  Neither IBSF nor any
IBSF Subsidiary is a party to any agreement or memorandum of understanding with,
or a party to any commitment letter,  board resolution submitted to a regulatory
authority or similar undertaking to, or is subject to any order or directive by,
or is a recipient  of any  extraordinary  supervisory  letter  from,  any court,
governmental   authority  or  other  regulatory  or  administrative   agency  or
commission,   domestic  or  foreign  ("Governmental   Entity")  which  restricts
materially the conduct of its business,  or in any manner relates to its capital
adequacy, its credit or reserve policies or its management, except for those the
existence  of which has been  disclosed in writing to HUBCO by IBSF prior to the
date of this  Agreement,  nor has IBSF been advised by any  Governmental  Entity
that  it  is  contemplating   issuing  or  requesting  (or  is  considering  the
appropriateness  of issuing or requesting)  any such order,  decree,  agreement,
memorandum of understanding, extraordinary supervisory letter, commitment letter
or similar submission,  except as disclosed in writing to HUBCO by IBSF prior to
the date of this Agreement.  Neither IBSF nor any IBSF Subsidiary is required by
Section  32 of the  Federal  Deposit  Insurance  Act to give  prior  notice to a
Federal banking agency of the proposed addition of an individual to its board of
directors or the  employment  of an individual  as a senior  executive  officer,
except  as  disclosed  in  writing  to HUBCO  by IBSF  prior to the date of this
Agreement.

                  3.20.  Year 2000  Compliance.  IBSF and the IBSF  Subsidiaries
have taken all reasonable  steps  necessary to address the software,  accounting
and record keeping issues raised in order for the data  processing  systems used
in the business  conducted by IBSF and the IBSF Subsidiaries to be substantially
Year 2000 compliant on or before the end of 1999 and, except as set forth in the
IBSF  Disclosure  Schedule,  IBSF does not expect the future cost of  addressing
such issues to be material.  Neither IBSF nor any IBSF Subsidiary has received a
rating of less than satisfactory from any bank regulatory agency with respect to
Year 2000 compliance.

                  3.21.  Accounting  for the Merger:  Reorganization.  As of the
date hereof, after reviewing the terms of this Agreement,  the stock repurchases
by HUBCO and IBSF,  and the employee  benefit plans of IBSF and the  Association
with IBSF's independent auditors,  IBSF does not have any reason to believe that
the  Merger  will  fail  to  qualify  (i)  for  pooling-of-interests  accounting
treatment  under GAAP, or (ii) as a  reorganization  under Section 368(a) of the
Code.

                  3.22.  Disclosure.  No representation or warranty contained in
Article III of this Agreement  contains any untrue  statement of a material fact
or omits to state a material fact  necessary to make the  statements  herein not
misleading.


              ARTICLE IV - REPRESENTATIONS AND WARRANTIES OF HUBCO

                  References  herein to the "HUBCO  Disclosure  Schedule"  shall
mean all of the  disclosure  schedules  required by this Article IV, dated as of
the date hereof and  referenced  to the  specific  sections and  subsections  of
Article IV of this  Agreement,  which have been  delivered on the date hereof by
HUBCO to IBSF. HUBCO hereby represents and warrants to IBSF as follows:

                  4.1.  Corporate Organization.

                  (a) HUBCO is a corporation duly organized and validly existing
and in good  standing  under the laws of the State of New Jersey.  HUBCO has the
corporate  power and authority to own or lease all of its  properties and assets
and to carry on its business as it is now being conducted,  and is duly licensed
or  qualified  to do business and is in good  standing in each  jurisdiction  in
which the nature of the business conducted by it or the character or location of
the  properties  and  assets  owned or  leased  by it makes  such  licensing  or
qualification necessary,  except where the failure to be so licensed,  qualified
or in good standing  would not have a material  adverse  effect on the business,
operations,  assets or financial  condition of HUBCO and the HUBCO  Subsidiaries
(defined below), taken as a whole. HUBCO is registered as a bank holding company
under the Bank Holding Company Act of 1956, as amended (the "BHCA").

                  (b) Each HUBCO  Subsidiary  is listed in the HUBCO  Disclosure
Schedule. For purposes of this Agreement,  the term "HUBCO Subsidiary" means any
corporation,  partnership,  joint  venture or other legal  entity in which HUBCO
directly or  indirectly,  owns at least a 50% stock or other equity  interest or
for which HUBCO, directly or indirectly, acts as a general partner provided that
to the extent that any  representation  or warranty  set forth  herein  covers a
period of time prior to the date of this Agreement,  the term "HUBCO Subsidiary"
shall  include any entity which was an HUBCO  Subsidiary at any time during such
period.  Each HUBCO  Subsidiary is duly organized and validly existing under the
laws of the  jurisdiction of its  incorporation.  The Bank is a  state-chartered
commercial  banking  corporation  duly organized and validly  existing under the
laws of the State of New  Jersey.  Lafayette  American  Bank and  Trust  Company
("Lafayette") is duly organized and validly existing under the laws of the State
of  Connecticut.  All  eligible  accounts of  depositors  issued by the Bank and
Lafayette  are  insured by the Bank  Insurance  Fund of the FDIC  ("BIF") to the
fullest extent  permitted by law. Each HUBCO  Subsidiary has the corporate power
and authority to own or lease all of its  properties  and assets and to carry on
its business as it is now being  conducted  and is duly licensed or qualified to
do business in each  jurisdiction in which the nature of the business  conducted
by it or the character or location of the  properties and assets owned or leased
by it makes such licensing or qualification necessary,  except where the failure
to be so licensed or qualified  would not have a material  adverse effect on the
business,  operations,  assets  or  financial  condition  of HUBCO and the HUBCO
Subsidiaries,  taken as a whole. The HUBCO  Disclosure  Schedule sets forth true
and complete copies of the Certificate of  Incorporation  and Bylaws of HUBCO as
in effect on the date hereof.

                  4.2.  Capitalization.  The  authorized  capital stock of HUBCO
consists of 53,045,000 common shares,  no par value ("HUBCO Common Stock"),  and
10,300,000 shares of preferred stock ("HUBCO Authorized Preferred Stock"). As of
March 26, 1998,  there were  22,648,970  shares of HUBCO Common Stock issued and
outstanding,  and no  shares  of  treasury  stock,  and  1,000  shares  of HUBCO
Authorized  Preferred Stock outstanding,  all of which were designated Series B,
no par value,  Convertible  Preferred  Stock.  Except as  described in the HUBCO
Disclosure Schedule, there are no shares of HUBCO Common Stock issuable upon the
exercise of outstanding  stock options or otherwise.  All issued and outstanding
shares of HUBCO  Common  Stock and HUBCO  Authorized  Preferred  Stock,  and all
issued and  outstanding  shares of capital stock of HUBCO's  Subsidiaries,  have
been duly authorized and validly issued, are fully paid,  nonassessable and free
of  preemptive  rights,  and are free  and  clear  of all  liens,  encumbrances,
charges,  restrictions or rights of third parties. All of the outstanding shares
of capital stock of the HUBCO  Subsidiaries are owned by HUBCO free and clear of
any  liens,  encumbrances,  charges,  restrictions  or rights of third  parties.
Except as  described in the HUBCO  Disclosure  Schedule,  neither  HUBCO nor any
HUBCO  Subsidiary  has  granted  or is bound by any  outstanding  subscriptions,
options, warrants, calls, commitments or agreements of any character calling for
the  transfer,  purchase or issuance of any shares of capital  stock of HUBCO or
any HUBCO  Subsidiary  or any  securities  representing  the right to  purchase,
subscribe  or  otherwise  receive  any  shares  of  such  capital  stock  or any
securities  convertible  into any such shares,  and there are no  agreements  or
understandings with respect to voting of any such shares.

                  4.3.  Authority; No Violation.

                  (a)  Subject  to the  receipt  of all  necessary  governmental
approvals,  HUBCO has full corporate  power and authority to execute and deliver
this  Agreement  and to  consummate  the  transactions  contemplated  hereby  in
accordance  with the terms hereof.  The execution and delivery of this Agreement
and the consummation of the transactions  contemplated hereby have been duly and
validly  approved  by the Board of  Directors  of HUBCO in  accordance  with its
Certificate of  Incorporation  and applicable laws and  regulations.  Except for
such  approvals,  no  other  corporate  proceedings  on the  part of  HUBCO  are
necessary to consummate the  transactions  so  contemplated.  This Agreement has
been duly and validly  executed and  delivered by HUBCO and  constitutes a valid
and binding  obligation of HUBCO,  enforceable  against HUBCO in accordance with
its  terms,  except  to  the  extent  that  enforcement  may be  limited  by (i)
bankruptcy,    insolvency,    reorganization,    moratorium,    conservatorship,
receivership  or other  similar laws now or  hereafter in effect  relating to or
affecting  the  enforcement  of  creditors'  rights  generally  or the rights of
creditors of bank holding  companies,  (ii) general  equitable  principles,  and
(iii)  laws  relating  to  the  safety  and  soundness  of  insured   depository
institutions  and  except  that no  representation  is made as to the  effect or
availability of equitable remedies or injunctive relief..

                  (b) Neither the  execution  or delivery of this  Agreement  by
HUBCO, nor the consummation by HUBCO of the transactions  contemplated hereby in
accordance  with the terms hereof,  or compliance by HUBCO with any of the terms
or  provisions  hereof will (i)  violate any  provision  of the  Certificate  of
Incorporation or Bylaws of HUBCO,  (ii) assuming that the consents and approvals
set forth below are duly obtained,  violate any statute, code, ordinance,  rule,
regulation, judgment, order, writ, decree or injunction applicable to HUBCO, any
HUBCO  Subsidiary,  or any of their  respective  properties or assets,  or (iii)
violate,  conflict  with,  result in a breach of any provision of,  constitute a
default  (or an event  which,  with  notice  or lapse  of time,  or both,  would
constitute  a default)  under,  result in the  termination  of,  accelerate  the
performance  required  by,  or  result in the  creation  of any  lien,  security
interest,  charge or other  encumbrance  upon any of the properties or assets of
HUBCO or any HUBCO Subsidiary  under any of the terms,  conditions or provisions
of any note, bond, mortgage, indenture, deed of trust, license, lease, agreement
or other  instrument or obligation to which HUBCO is a party,  or by which it or
any of their properties or assets may be bound or affected, except, with respect
to (ii) and (iii) above,  such as individually or in the aggregate will not have
a  material  adverse  effect on the  business,  operation,  assets or  financial
condition of HUBCO and the HUBCO Subsidiaries,  taken as a whole, and which will
not  prevent  or  materially   delay  the   consummation  of  the   transactions
contemplated  hereby.  Except  for  consents  and  approvals  of or  filings  or
registrations  with or  notices  to the FDIC,  the FRB,  the OTS,  the SEC,  the
Department, or the Secretary of State of New Jersey, and the possible need under
the Nasdaq rules to obtain HUBCO shareholder  approval, no consents or approvals
of or filings or registrations  with or notices to any third party or any public
body or authority are  necessary on behalf of HUBCO in  connection  with (x) the
execution and delivery by HUBCO of this Agreement,  and (y) the  consummation by
HUBCO of the Merger and the other transactions  contemplated hereby, except such
as are listed in the HUBCO Disclosure  Schedule or in the aggregate will not (if
not obtained) have a material adverse effect on the business,  operation, assets
or financial condition of HUBCO and the HUBCO Subsidiaries, taken as a whole. To
the best of HUBCO's  knowledge,  no fact or  condition  exists  which  HUBCO has
reason to believe will prevent it from obtaining the aforementioned consents and
approvals.

                  4.4.  Financial Statements.

                  (a) The HUBCO  Disclosure  Schedule  sets forth  copies of the
consolidated  statements of financial condition of HUBCO as of December 31, 1996
and  1997,  and the  related  consolidated  statements  of  income,  changes  in
stockholders'  equity and of cash flows for the periods  ended  December  31, in
each of the three fiscal years 1995 through  1997, in each case  accompanied  by
the audit report of Arthur Andersen LLP ("Arthur Andersen"),  independent public
accountants   with  respect  to  HUBCO   (collectively,   the  "HUBCO  Financial
Statements").  The HUBCO Financial Statements (including the related notes) have
been prepared in accordance  with GAAP  consistently  applied during the periods
involved  (except  as may be  indicated  therein or in the notes  thereto),  and
fairly present the consolidated financial position of HUBCO as of the respective
dates set forth  therein,  and the related  consolidated  statements  of income,
changes in stockholders'  equity and of cash flows (including the related notes,
where applicable) fairly present the consolidated results of operations, changes
in  stockholders'  equity  and cash  flows of HUBCO  for the  respective  fiscal
periods set forth therein.

                  (b) The books and records of HUBCO and the HUBCO  Subsidiaries
are being maintained in material compliance with applicable legal and accounting
requirements, and reflect only actual transactions.

                  (c)  Except  as and  to the  extent  reflected,  disclosed  or
reserved  against  in  the  HUBCO  Financial  Statements  (including  the  notes
thereto),  as  of  December  31,  1997  neither  HUBCO  nor  any  of  the  HUBCO
Subsidiaries  had  any  obligation  or  liability,  whether  absolute,  accrued,
contingent  or  otherwise,  material  to the  business,  operations,  assets  or
financial  condition  of  HUBCO  or any of the  HUBCO  Subsidiaries  which  were
required by GAAP (consistently  applied) to be disclosed in HUBCO's consolidated
statement of condition as of December 31, 1997 or the notes thereto.  Except for
the  transactions  contemplated  by  this  Agreement,  and  the  other  proposed
acquisitions  by HUBCO  reflected  in any Form 8-K  filed by HUBCO  with the SEC
since December 31, 1997, neither HUBCO nor any HUBCO Subsidiary has incurred any
liabilities  since  December 31, 1997 except in the ordinary  course of business
and consistent  with past practice  (including for other pending or contemplated
acquisitions).

                  4.5.  Broker's  and Other Fees.  Neither  HUBCO nor any of its
directors  or  officers  has  employed  any  broker or finder  or  incurred  any
liability for any broker's or finder's fees or  commissions  in connection  with
any of the transactions contemplated by this Agreement.

                  4.6. Absence of Certain Changes or Events.  There has not been
any HUBCO  Material  Adverse  Change since  December 31, 1997 and to the best of
HUBCO's knowledge,  no facts or condition exists which HUBCO believes will cause
a HUBCO Material  Adverse Change in the future.  "HUBCO Material Adverse Change"
means any change  which is material  and adverse to the  consolidated  financial
condition,  results  of  operations,  business  or assets of HUBCO and the HUBCO
Subsidiaries  taken as a whole,  other  than  (i) a change  in the  value of the
respective investment and loan portfolios of HUBCO and the HUBCO Subsidiaries as
the result of a change in  interest  rates  generally,  (ii) a change  occurring
after the date  hereof in any  federal or state law,  rule or  regulation  or in
GAAP,  which change affects banking  institutions  generally,  (iii)  reasonable
expenses  incurred  in  connection  with  this  Agreement  and the  transactions
contemplated  hereby,  (iv) changes  resulting from acquisitions by HUBCO or any
HUBCO  Subsidiary  pending  on the date  hereof  and known to IBSF,  other  than
changes resulting from facts not disclosed to, or otherwise known by, IBSF on or
prior to the date hereof,  or (v) the entry,  after the date hereof, by HUBCO or
any HUBCO Subsidiary into an agreement to acquire another entity.

                  4.7  Legal  Proceedings.  Except  as  disclosed  in the  HUBCO
Disclosure  Schedule,  and except for ordinary routine litigation  incidental to
the  business  of  HUBCO  or its  Subsidiaries,  neither  HUBCO  nor  any of its
Subsidiaries  is a party to any,  and  there are no  pending  or, to the best of
HUBCO's  knowledge,   threatened  legal,   administrative,   arbitral  or  other
proceedings,  claims,  actions  or  governmental  investigations  of any  nature
against HUBCO or any of its Subsidiaries which, if decided adversely to HUBCO or
its Subsidiaries, are reasonably likely to have a material adverse effect on the
business,   operations,   assets  or   financial   condition  of  HUBCO  or  its
Subsidiaries,  taken as a whole.  Except as  disclosed  in the HUBCO  Disclosure
Schedule,  neither  HUBCO nor any of its  Subsidiaries  is a party to any order,
judgment  or decree  entered in any lawsuit or  proceeding  which is material to
HUBCO or its Subsidiaries.

                  4.8  Reports.  Since  January  1,  1996,  HUBCO  has filed all
reports  that it was  required  to file with the SEC under the 1934 Act,  all of
which complied in all material respects with all applicable  requirements of the
1934  Act  and  the  rules  and  regulations  adopted  thereunder.  As of  their
respective  dates,  each such  report  and each  registration  statement,  proxy
statement, form or other document filed by HUBCO with the SEC, including without
limitation,  any financial  statements or schedules  included  therein,  did not
contain any untrue statement of a material fact or omit to state a material fact
required to be stated therein or necessary to make the statements  made therein,
in light of the  circumstances  under  which  they were  made,  not  misleading,
provided  that  information  as of a  later  date  shall  be  deemed  to  modify
information as of an earlier date.  Since January 1, 1996,  HUBCO and each HUBCO
Subsidiary has duly filed all material  forms,  reports and documents which they
were  required to file with each agency  charged with  regulating  any aspect of
their business.

                  4.9 HUBCO Information.  The information  relating to HUBCO and
its Subsidiaries  (including,  without limitation,  information  regarding other
transactions  which HUBCO is  required  to  disclose),  this  Agreement  and the
transactions  contemplated  hereby  in  the  Registration  Statement  and  Proxy
Statement-Prospectus  (as defined in Section 5.6(a)  hereof),  as of the date of
the mailing of the Proxy Statement-Prospectus,  and up to and including the date
of the meeting of stockholders of IBSF to which such Proxy  Statement-Prospectus
relates,  will not contain any untrue  statement  of a material  fact or omit to
state a material  fact  required to be stated  therein or  necessary in order to
make the statements  therein, in light of the circumstances under which they are
made, not misleading.  The Registration Statement shall comply as to form in all
material  respects  with the  provisions  of the 1933 Act,  the 1934 Act and the
rules and regulations promulgated thereunder.

                  4.10  Compliance  With  Applicable Law. Except as set forth in
the HUBCO Disclosure Schedule,  each of HUBCO and HUBCO's Subsidiaries holds all
material  licenses,  franchises,  permits and  authorizations  necessary for the
lawful  conduct of its business,  and has complied with and is not in default in
any respect under any applicable law, statute,  order, rule, regulation,  policy
and/or guideline of any federal,  state or local governmental authority relating
to  HUBCO  or  HUBCO's  Subsidiaries  (including  without  limitation  consumer,
community and fair lending laws) (other than where such default or noncompliance
will not result in a material adverse effect on the business, operations, assets
or financial  condition of HUBCO and HUBCO's  Subsidiaries taken as a whole) and
HUBCO  has not  received  notice  of  violation  of,  and  does  not know of any
violations of, any of the above.

                  4.11  Funding and Capital  Adequacy.  At the  Effective  Time,
after  giving pro forma  effect to the Merger  and any other  acquisition  which
HUBCO or its Subsidiaries have agreed to consummate,  HUBCO will be deemed "well
capitalized" under prompt corrective action regulatory capital requirements.

                  4.12 HUBCO  Common  Stock.  As of the date  hereof,  HUBCO has
available  and reserved  shares of HUBCO Common  Stock  sufficient  for issuance
pursuant  to the  Merger  and upon the  exercise  of  Stock  Options  subsequent
thereto.  The HUBCO Common Stock to be issued hereunder  pursuant to the Merger,
and upon exercise of the Stock Options,  when so issued, will be duly authorized
and validly issued,  fully paid,  nonassessable,  free of preemptive  rights and
free and clear of all liens,  encumbrances or restrictions created by or through
HUBCO, with no personal liability attaching to the ownership thereof.  The HUBCO
Common Stock to be issued hereunder pursuant to the Merger, and upon exercise of
the Stock  Options,  when so issued,  will be registered  under the 1933 Act and
issued in  accordance  with all  applicable  state and federal  laws,  rules and
regulations, and will be approved or listed for trading on Nasdaq.

                  4.13  Agreements with Bank  Regulators.  Neither HUBCO nor any
HUBCO  Subsidiary is a party to any  agreement or  memorandum  of  understanding
with,  or a party to any  commitment  letter,  board  resolution  submitted to a
regulatory  authority or similar  undertaking  to, or is subject to any order or
directive by, or is a recipient of any  extraordinary  supervisory  letter from,
any Government Entity which restricts materially the conduct of its business, or
in any manner relates to its capital adequacy, its credit or reserve policies or
its  management,  except for those the existence of which has been  disclosed in
writing to IBSF by HUBCO prior to the date of this Agreement, nor has HUBCO been
advised  by  any  Governmental  Entity  that  it  is  contemplating  issuing  or
requesting (or is considering the  appropriateness of issuing or requesting) any
such  order,  decree,  agreement,  memorandum  of  understanding,  extraordinary
supervisory letter, commitment letter or similar submission, except as disclosed
in writing to IBSF by HUBCO prior to the date of this  Agreement.  Neither HUBCO
nor any HUBCO  Subsidiary  is  required  by  Section 32 of the  Federal  Deposit
Insurance Act to give prior notice to a Federal  banking  agency of the proposed
addition of an  individual  to its board of  directors or the  employment  of an
individual as a senior executive officer, except as disclosed in writing to IBSF
by HUBCO prior to the date of this Agreement.

                  4.14     Taxes and Tax Returns.

                  (a) HUBCO and HUBCO's  subsidiaries have duly filed (and until
the  Effective  Time will so file) all  Returns  required to be filed by them in
respect of any  federal,  state and local taxes  (including  withholding  taxes,
penalties  or other  payments  required)  and have  duly  paid  (and  until  the
Effective Time will so pay) all such taxes due and payable,  other than taxes or
other charges which are being  contested in good faith (and disclosed to IBSF in
writing).  HUBCO and HUBCO's  subsidiaries  have  established on their books and
records  reserves  that are adequate  for the payment of all federal,  state and
local  taxes not yet due and  payable,  but are  incurred  in  respect  of HUBCO
through such date. The HUBCO Disclosure  Schedule  identifies the federal income
tax returns of HUBCO and its  Subsidiaries  which have been  examined by the IRS
within the past six years.  No  deficiencies  were  asserted as a result of such
examinations which have not been resolved and paid in full. The HUBCO Disclosure
Schedule  identifies  the  applicable  state income tax returns of HUBCO and its
Subsidiaries  which  have  been  examined  by  the  applicable  authorities.  No
deficiencies were asserted as a result of such examinations  which have not been
resolved and paid in full. To the best  knowledge of HUBCO,  there are no audits
or other  administrative  or court  proceedings  presently pending nor any other
disputes  pending with respect to, or claims  asserted for, taxes or assessments
upon  HUBCO or its  Subsidiaries,  nor has HUBCO or its  Subsidiaries  given any
currently  outstanding  waivers or comparable consents regarding the application
of the statute of limitations with respect to any taxes or Returns.

                  (b)  Except  as set forth in the  HUBCO  Disclosure  Schedule,
neither  HUBCO nor any  Subsidiary  of HUBCO (i) has  requested any extension of
time within which to file any Return which Return has not since been filed, (ii)
is a party to any agreement  providing  for the  allocation or sharing of taxes,
(iii) is required to include in income any adjustment pursuant to Section 481(a)
of the Code, by reason of a voluntary  change in accounting  method initiated by
HUBCO or any of its Subsidiaries (nor does HUBCO have any knowledge that the IRS
has proposed any such  adjustment  or change of  accounting  method) or (iv) has
filed a consent pursuant to Section 341(f) of the Code or agreed to have Section
341(f)(2) of the Code apply.

                  4.15     Employee Benefit Plans.

                  (a) HUBCO  and its  Subsidiaries  maintain  or  contribute  to
certain  "employee  pension benefit plans" (the "HUBCO Pension Plans"),  as such
term is defined  in Section  3(2)(A) of ERISA,  and  "employee  welfare  benefit
plans" (the "HUBCO Welfare  Plans"),  as such term is defined in Section 3(1) of
ERISA.  Since  September  2,  1974,  neither  HUBCO  nor its  subsidiaries  have
contributed  to any  "Multiemployer  Plan",  as such term is  defined in Section
3(37) of ERISA.

                  (b) HUBCO is not aware of any fact or circumstance which would
disqualify  any HUBCO  Pension  Plan or HUBCO  Welfare  Plan  that  could not be
retroactively corrected (in accordance with the procedures of the IRS).

                  (c) The present  value of all accrued  benefits  under each of
the HUBCO Pension  Plans subject to Title IV of ERISA,  based upon the actuarial
assumptions used for purposes of the most recent actuarial valuation prepared by
such HUBCO Pension Plan's actuary,  did not exceed the then current value of the
assets of such plans allocable to such accrued benefits.

                  (d) During the last six years,  the PBGC has not  asserted any
claim for liability against HUBCO or any of its subsidiaries  which has not been
paid in full.

                  (e) All premiums (and interest  charges and penalties for late
payment,  if applicable) due to the PBGC with respect to each HUBCO Pension Plan
have been paid. All contributions required to be made to each HUBCO Pension Plan
under the terms  thereof,  ERISA or other  applicable law have been timely made,
and all amounts  properly accrued to date as liabilities of HUBCO which have not
been paid have been properly recorded on the books of HUBCO.

                  (f) No "accumulated funding deficiency", within the meaning of
Section  412 of the Code,  has been  incurred  with  respect to any of the HUBCO
Pension Plans.

                  (g) There are no pending or, to the best  knowledge  of HUBCO,
threatened  or  anticipated  material  claims  (other  than  routine  claims for
benefits)  by, on behalf of or  against  any of the HUBCO  Pension  Plans or the
HUBCO  Welfare  Plans,  any  trusts  created  thereunder  or any  other  plan or
arrangement identified in the HUBCO Disclosure Schedule.

                  (h)  Except  with  respect  to  customary  health,   life  and
disability benefits or as disclosed in the HUBCO Disclosure Schedule,  HUBCO has
no unfunded benefit obligations which are not accounted for by reserves shown on
the financial  statements and established  under GAAP or otherwise noted on such
financial statements.

                  4.16  Contracts.  Except as disclosed in the HUBCO  Disclosure
Schedule, neither HUBCO nor any of its Subsidiaries, or to the best knowledge of
HUBCO, any other party thereto,  is in default in any material respect under any
material lease,  contract,  mortgage,  promissory  note, deed of trust,  loan or
other commitment  (except those under which a banking  subsidiary of HUBCO is or
will be the creditor) or arrangement,  except for defaults which individually or
in the  aggregate  would not have a  material  adverse  effect on the  business,
operations,  assets or financial condition of HUBCO and its subsidiaries,  taken
as a whole.

                  4.17     Properties and Insurance.

                  (a) HUBCO and its Subsidiaries have good and, as to owned real
property,  marketable title to all material assets and properties,  whether real
or personal,  tangible or intangible,  reflected in HUBCO's consolidated balance
sheet as of December 31, 1997, or owned and acquired  subsequent thereto (except
to the extent that such  assets and  properties  have been  disposed of for fair
value in the ordinary course of business since December 31, 1997), subject to no
encumbrances,  liens, mortgages, security interests or pledges, except (i) those
items that secure  liabilities  that are  reflected in said balance sheet or the
notes  thereto or that secure  liabilities  incurred in the  ordinary  course of
business after the date of such balance sheet,  (ii) statutory liens for amounts
not yet  delinquent  or which are being  contested  in good  faith,  (iii)  such
encumbrances,   liens,   mortgages,   security  interests,   pledges  and  title
imperfections   that  are  not  in  the  aggregate  material  to  the  business,
operations,  assets, and financial condition of HUBCO and its subsidiaries taken
as a whole and (iv) with  respect to owned real  property,  title  imperfections
noted in title reports.  Except as disclosed in the HUBCO  Disclosure  Schedule,
HUBCO and its  Subsidiaries as lessees have the right under valid and subsisting
leases to occupy,  use,  possess and control all property leased by HUBCO or its
Subsidiaries in all material respects as presently occupied, used, possessed and
controlled by HUBCO and its Subsidiaries.

                  (b) The business  operations and all insurable  properties and
assets of HUBCO and its  Subsidiaries  are insured for their benefit against all
risks which,  in the reasonable  judgment of the management of HUBCO,  should be
insured  against,  in each case under  policies  or bonds  issued by insurers of
recognized  responsibility,  in such amounts with such  deductibles  and against
such risks and losses as are in the opinion of the  management of HUBCO adequate
for the  business  engaged  in by  HUBCO  and its  Subsidiaries.  As of the date
hereof,  neither  HUBCO nor any of its  Subsidiaries  has received any notice of
cancellation or notice of a material  amendment of any such insurance  policy or
bond or is in default under any such policy or bond,  no coverage  thereunder is
being disputed and all material  claims  thereunder  have been filed in a timely
fashion.

                  4.18.  Environmental Matters. Except as disclosed in the HUBCO
Disclosure Schedule,  neither HUBCO nor any of its Subsidiaries has received any
written notice, citation,  claim, assessment,  proposed assessment or demand for
abatement alleging that HUBCO or any of its Subsidiaries  (either directly or as
a  successor-in-interest  in  connection  with the  enforcement  of  remedies to
realize the value of properties  serving as collateral for outstanding loans) is
responsible  for the  correction or cleanup of any condition  resulting from the
violation  of any law,  ordinance  or other  governmental  regulation  regarding
environmental  matters  which  correction  or cleanup  would be  material to the
business,   operations,   assets  or  financial   condition  of  HUBCO  and  its
Subsidiaries  taken as a whole.  Except as  disclosed  in the  HUBCO  Disclosure
Schedule,  HUBCO has no  knowledge  that any toxic or  hazardous  substances  or
materials  have been emitted,  generated,  disposed of or stored on any property
currently owned or leased by HUBCO or any of its subsidiaries in any manner that
violates  or,  after the lapse of time is  reasonably  likely  to  violate,  any
presently  existing  federal,  state or local  law or  regulation  governing  or
pertaining to such substances and materials, the violation of which would have a
material  adverse  effect  on the  business,  operations,  assets  or  financial
condition of HUBCO and its Subsidiaries, taken as a whole.

                  4.19  Reserves.  As of December 31, 1997,  the  allowance  for
possible loan losses in the HUBCO  Financial  Statements was adequate based upon
all factors  required to be considered by HUBCO at that time in determining  the
amount of such  allowance.  The  methodology  used to compute the  allowance for
possible loan losses complies in all material respects with all applicable FDIC,
Connecticut Department of Banking and New Jersey Department of Banking policies.
As of December 31, 1997,  the  valuation  allowance  for OREO  properties in the
HUBCO  Financial  Statements was adequate based upon all factors  required to be
considered by HUBCO at that time in determining the amount of such allowance.

                  4.20. Year 2000 Compliance.  HUBCO and the HUBCO  Subsidiaries
have taken all reasonable  steps  necessary to address the software,  accounting
and record keeping issues raised in order for the data  processing  systems used
in  the  business   conducted  by  HUBCO  and  the  HUBCO   Subsidiaries  to  be
substantially  Year 2000  compliant  on or before the end of 1999 and HUBCO does
not expect the future cost of  addressing  such issues to be  material.  Neither
HUBCO nor any HUBCO  Subsidiary has received a rating of less than  satisfactory
from any bank regulatory agency with respect to Year 2000 compliance.

                  4.21 Accounting for the Merger; Reorganization. As of the date
hereof,  after reviewing the terms of this Agreement,  the stock  repurchases by
HUBCO and IBSF, and the employee  benefit plans of IBSF and the Association with
HUBCO's independent auditors, HUBCO does not have any reason to believe that the
Merger will fail to qualify (i) for  pooling-of-interests  treatment under GAAP,
or (ii) as a  reorganization  under  Section  368(a) of the Code. As of the date
hereof,  neither HUBCO nor any HUBCO  Subsidiary  owns any shares of IBSF Common
Stock.

                  4.22 No Approval of HUBCO's  Shareholders  Currently Required.
Based upon laws and  regulations  applicable  to HUBCO and  currently in effect,
including  the rules,  regulations  and policies of the NASD,  as of the date of
this Agreement,  assuming that HUBCO's  pending  acquisitions of MSB Bancorp and
Poughkeepsie  Financial  Corp.  are  consummated  prior to closing  the  Merger,
neither  approval of this Agreement by the shareholders of HUBCO nor approval of
the  transactions  contemplated  hereby  by the  shareholders  of HUBCO  will be
required.

                  4.23 Disclosure.  No representation  or warranty  contained in
Article IV of this Agreement contains any untrue statement of a material fact or
omits to state a  material  fact  necessary  to make the  statements  herein not
misleading.

         or any similar governing documents;

                  (b) change any provision of its Bylaws  without the consent of

         quarterly  amount equal to $0.10 per share,  with the dividend  payment
         dates to be  coordinated  with  HUBCO,  it being the  intention  of the
         parties  that  the  shareholders  of  IBSF  receive  dividends  for any
         particular  calendar  quarter  on either the IBSF  Common  Stock or the
         HUBCO Common Stock acquired in exchange  therefor pursuant to the terms
         of this  Agreement  but  not  both;  provided,  further,  that  nothing
         contained  herein  shall  be  deemed  to  affect  the  ability  of  the
         Association to pay dividends on its capital stock to IBSF;

                  (d)  grant  any  severance  or  termination  pay  (other  than

         and  disclosed to HUBCO in the IBSF  Disclosure  Schedule) to, or enter
         into or amend any  employment or severance  agreement  with, any of its
         directors,  officers or employees;  adopt any new employee benefit plan

         IBSF or the Association;

                  (f) make any capital  expenditures in excess of $50,000 in the

         date hereof, expenditures necessary to maintain existing assets in good
         repair  and  expenditures   described  in  business  plans  or  budgets
         previously  furnished  to HUBCO,  except as set forth in Section 5.2 of
         the IBSF Disclosure Schedule;

         five years;

                  (i) make any  material  change in its  accounting  methods  or
         practices,  other than changes  required in accordance  with  generally
         accepted accounting principles or regulatory authorities;

         Agreement  not being true and  correct in any  material  respect at the
         Effective Time or that would cause any of its conditions to Closing not
         to be satisfied;

                  (k) without  first  conferring  with HUBCO,  make or commit to
         make any new loan or other extension of credit in an amount of $500,000
         or more,  renew for a period in excess of one year any existing loan or
         other extension of credit in an amount of $500,000 or more, or increase

         identified on the IBSF  Disclosure  Schedule and  residential  mortgage
         loans made in the ordinary  course of business in accordance  with past
         practice; or

                  (l) agree to do any of the foregoing.

                  5.3. No  Solicitation.  So long as this  Agreement  remains in
effect, IBSF and the Association shall not, directly or indirectly, encourage or
solicit or hold discussions or negotiations with, or provide any information to,
any person,  entity or group (other than HUBCO) concerning any merger or sale of
shares of capital stock or sale of substantial  assets or liabilities not in the
ordinary  course of  business,  or similar  transactions  involving  IBSF or the
Association (an "Acquisition Transaction").  Notwithstanding the foregoing, IBSF
may enter into discussions or negotiations or provide  information in connection
with an unsolicited possible  Acquisition  Transaction if the Board of Directors
of IBSF,  after  consulting  with  counsel,  determines  in the  exercise of its
fiduciary  responsibilities  that such  discussions  or  negotiations  should be
commenced  or  such  information  should  be  furnished.   IBSF  shall  promptly
communicate to HUBCO the terms of any proposal,  whether written or oral,  which
it may receive in respect of any such Acquisition  Transaction and the fact that
it is having discussions or negotiations with a third party about an Acquisition
Transaction.

                  5.4. Current  Information.  During the period from the date of
this Agreement to the Effective  Time,  each of IBSF and HUBCO will cause one or
more of its designated  representatives  to confer with  representatives  of the
other  party  on a  monthly  or more  frequent  basis  regarding  its  business,
operations,  properties,  assets and financial condition and matters relating to
the completion of the transactions contemplated herein. On a monthly basis, IBSF
agrees to provide  HUBCO,  and HUBCO  agrees to provide  IBSF,  with  internally
prepared  profit  and loss  statements  no later than 25 days after the close of
each calendar month. As soon as reasonably available,  but in no event more than
45 days after the end of each fiscal quarter (other than the last fiscal quarter
of each fiscal year),  IBSF will deliver to HUBCO and HUBCO will deliver to IBSF
their respective quarterly reports on Form 10-Q, as filed with the SEC under the
1934 Act.  As soon as  reasonably  available,  but in no event more than 90 days
after the end of each calendar  year,  IBSF will deliver to HUBCO and HUBCO will
deliver to IBSF their  respective  Annual Reports on Form 10-K as filed with the
SEC under the 1934 Act.

                  5.5.  Access to Properties and Records; Confidentiality.

                  (a)  IBSF  and the  Association  shall  permit  HUBCO  and its
representatives,  and HUBCO shall  permit,  and cause each HUBCO  Subsidiary  to
permit,  IBSF and its  representatives,  reasonable  access to their  respective
properties,   and  shall   disclose   and  make   available  to  HUBCO  and  its
representatives,  or IBSF and its representatives as the case may be, all books,
papers  and  records  relating  to  its  assets,  stock  ownership,  properties,
operations,  obligations  and  liabilities,  including,  but not limited to, all
books of account  (including the general ledger),  tax records,  minute books of
directors'  and  shareholders'  meetings,   organizational  documents,   Bylaws,
material  contracts  and  agreements,  filings  with any  regulatory  authority,
accountants' work papers,  litigation files, plans affecting employees,  and any
other business activities or prospects in which HUBCO and its representatives or
IBSF and its representatives may have a reasonable interest. Neither party shall
be required to provide access to or to disclose information where such access or
disclosure  would  violate  or  prejudice  the  rights  of any  customer,  would
contravene  any law,  rule,  regulation,  order or  judgment  or would waive any
privilege.  The parties will use their reasonable best efforts to obtain waivers
of any such restriction  (other than waivers of the  attorney-client  privilege)
and in any event  make  appropriate  substitute  disclosure  arrangements  under
circumstances  in  which  the  restrictions  of the  preceding  sentence  apply.
Notwithstanding  the foregoing,  IBSF acknowledges that HUBCO may be involved in
discussions  concerning  other  potential  acquisitions  and HUBCO  shall not be
obligated to disclose such  information  to IBSF except as such  information  is
disclosed to HUBCO's shareholders generally.

                  (b) All information furnished by the parties hereto previously
in  connection  with  transactions  contemplated  by this  Agreement or pursuant
hereto  shall  be  used  solely  for  the  purpose  of  evaluating   the  Merger
contemplated  hereby  and shall be  treated  as the sole  property  of the party
delivering the information until consummation of the Merger  contemplated hereby
and, if such Merger shall not occur,  each party and each party's advisors shall
return  to  the  other  party  all  documents  or  other  materials  containing,
reflecting or referring to such information,  will not retain any copies of such
information, shall use its reasonable best efforts to keep confidential all such
information,  and shall not directly or indirectly use such  information for any
competitive  or  other  commercial  purposes.  In  the  event  that  the  Merger
contemplated  hereby does not occur,  all  documents,  notes and other  writings
prepared by a party hereto or its advisors based on information furnished by the
other party shall be promptly destroyed. The obligation to keep such information
confidential  shall continue for five years from the date the proposed Merger is
abandoned  but  shall  not  apply to (i) any  information  which  (A) the  party
receiving the  information  can establish by convincing  evidence was already in
its possession prior to the disclosure thereof to it by the other party; (B) was
then  generally  known to the public;  (C) became known to the public through no
fault of the party receiving such information; or (D) was disclosed to the party
receiving  such  information  by a third  party  not bound by an  obligation  of
confidentiality;  or (ii)  disclosures  pursuant  to a legal  requirement  or in
accordance with an order of a court of competent jurisdiction.

                  5.6.  Regulatory Matters.

                  (a) For the purposes of holding the  Shareholders  Meeting (as
such term is defined in Section 5.7 hereof),  and  qualifying  under  applicable
federal and state  securities  laws the HUBCO  Common Stock to be issued to IBSF
shareholders in connection  with the Merger,  the parties hereto shall cooperate
in the preparation and filing by HUBCO with the SEC of a Registration  Statement
including a combined proxy  statement and  prospectus  satisfying all applicable
requirements of applicable  state and federal laws,  including the 1933 Act, the
1934 Act and  applicable  state  securities  laws and the rules and  regulations
thereunder  (such proxy  statement and prospectus in the form mailed by IBSF and
HUBCO  to the  IBSF  shareholders  together  with  any  and  all  amendments  or
supplements    thereto,    being    herein    referred    to   as   the   "Proxy
Statement-Prospectus"  and the various  documents to be filed by HUBCO under the
1933 Act with the SEC to register the HUBCO Common Stock for sale, including the
Proxy  Statement-Prospectus,   are  referred  to  herein  as  the  "Registration
Statement").

                  (b) HUBCO shall furnish IBSF with such information  concerning
HUBCO and its Subsidiaries (including, without limitation, information regarding
other transactions which HUBCO is required to disclose) as is necessary in order
to  cause  the  Proxy  Statement-Prospectus,  insofar  as  it  relates  to  such
corporations,  to comply with Section  5.6(a) hereof.  HUBCO agrees  promptly to
advise IBSF if at any time prior to the  Shareholders'  Meeting any  information
provided  by  HUBCO  in the  Proxy  Statement-Prospectus  becomes  incorrect  or
incomplete  in any  material  respect  and  promptly  to  provide  IBSF with the
information needed to correct such inaccuracy or omission.  HUBCO shall promptly
furnish IBSF with such supplemental  information as may be necessary in order to
cause the Proxy  Statement-Prospectus,  insofar  as it  relates to HUBCO and the
HUBCO  Subsidiaries,  to comply with Section 5.6(a) after the mailing thereof to
IBSF shareholders.

                  (c) IBSF shall furnish HUBCO with such information  concerning
IBSF as is necessary in order to cause the Proxy  Statement-Prospectus,  insofar
as it relates  to IBSF,  to comply  with  Section  5.6(a)  hereof.  IBSF  agrees
promptly to advise HUBCO if at any time prior to the Shareholders'  Meeting, any
information provided by IBSF in the Proxy Statement-Prospectus becomes incorrect
or  incomplete  in any material  respect and promptly to provide  HUBCO with the
information  needed to correct such inaccuracy or omission.  IBSF shall promptly
furnish HUBCO with such supplemental information as may be necessary in order to
cause the Proxy  Statement-Prospectus,  insofar  as it  relates  to IBSF and the
Association  to comply with  Section  5.6(a)  after the mailing  thereof to IBSF
shareholders.

                  (d) HUBCO shall as promptly as  practicable  make such filings
as are necessary in connection  with the offering of the HUBCO Common Stock with
applicable  state  securities  agencies and shall use all reasonable  efforts to
qualify the offering of such stock under applicable state securities laws at the
earliest   practicable  date.  IBSF  shall  promptly  furnish  HUBCO  with  such
information  regarding the IBSF  shareholders  as HUBCO requires to enable it to
determine what filings are required hereunder.  IBSF authorizes HUBCO to utilize
in such filings the information  concerning IBSF and the Association provided to
HUBCO in connection with, or contained in, the Proxy Statement-Prospectus. HUBCO
shall  furnish  IBSF's  counsel  with  copies of all such  filings and keep IBSF
advised of the status  thereof.  HUBCO and IBSF shall as promptly as practicable
file the Registration Statement containing the Proxy  Statement-Prospectus  with
the SEC,  and each of HUBCO  and IBSF  shall  promptly  notify  the other of all
communications,  oral or  written,  with  the SEC  concerning  the  Registration
Statement and the Proxy Statement-Prospectus.

                  (e) HUBCO shall cause the HUBCO Common Stock issuable pursuant
to the Merger to be listed on Nasdaq at the  Effective  Time.  HUBCO shall cause
the HUBCO  Common  Stock which  shall be issuable  pursuant to exercise of Stock
Options to be accepted for listing on Nasdaq when issued.

                  (f) The parties  hereto will cooperate with each other and use
their reasonable best efforts to prepare all necessary documentation,  to effect
all necessary filings and to obtain all necessary permits,  consents,  approvals
and  authorizations of all third parties and Governmental  Entities necessary to
consummate the transactions  contemplated by this Agreement as soon as possible,
including, without limitation, those required by the FDIC, the FRB, the OTS, the
Department  and (if  required)  the DEP.  Without  limiting the  foregoing,  the
parties shall use reasonable  business efforts to file for approval or waiver by
the appropriate  bank regulatory  agencies within 45 days after the date hereof.
The  parties  shall  each have the right to review in  advance  (and shall do so
promptly) all filings with,  including all information relating to the other, as
the case may be, and any of their respective subsidiaries,  which appears in any
filing  made  with,  or  written  material  submitted  to,  any  third  party or
Governmental  Entity in connection  with the  transactions  contemplated by this
Agreement.

                  (g) Each of the parties will promptly  furnish each other with
copies of written  communications  received  by them or any of their  respective
subsidiaries  from, or delivered by any of the  foregoing  to, any  Governmental
Entity in respect of the transactions contemplated hereby.

                  (h)  IBSF  acknowledges  that  HUBCO  is in or  may  be in the
process  of  acquiring  other  banks  and  financial  institutions  and  that in
connection with such acquisitions,  information  concerning IBSF may be required
to be  included  in the  registration  statements,  if  any,  for  the  sale  of
securities of HUBCO or in SEC reports in connection with such acquisitions. IBSF
agrees to provide HUBCO with any information,  certificates,  documents or other
materials  about IBSF as are  reasonably  necessary to be included in such other
SEC reports or registration statements,  including registration statements which
may be filed by HUBCO prior to the Effective Time. IBSF shall use its reasonable
efforts  to cause  its  attorneys  and  accountants  to  provide  HUBCO  and any
underwriters  for HUBCO with any consents,  comfort  letters,  opinion  letters,
reports  or  information  which  are  necessary  to  complete  the  registration
statements and  applications for any such acquisition or issuance of securities.
HUBCO shall reimburse IBSF for reasonable  expenses thus incurred by IBSF should
this transaction be terminated for any reason. HUBCO shall not file with the SEC
any registration statement or amendment thereto or supplement thereof containing
information  regarding  IBSF unless IBSF shall have consented in writing to such
filing, which consent shall not be unreasonably delayed or withheld.

                  (i) Between the date of this Agreement and the Effective Time,
IBSF shall  cooperate  with HUBCO to  reasonably  conform  IBSF's  policies  and
procedures regarding  applicable  regulatory matters to those of HUBCO, as HUBCO
may reasonably identify to IBSF from time to time.

                  5.7.  Approval of  Shareholders.  IBSF will (i) take all steps
necessary  duly to call,  give  notice  of,  convene  and hold a meeting  of the
shareholders  of IBSF (the  "Shareholders  Meeting") for the purpose of securing
the  approval  of  shareholders   of  this   Agreement,   (ii)  subject  to  the
qualification  set  forth in  Section  5.3  hereof  and the  right not to make a
recommendation  or to withdraw a  recommendation  if (x) its  investment  banker
withdraws its fairness opinion prior to the Shareholders'  Meeting or (y) IBSF's
Board of Directors, after consulting with counsel, determines in the exercise of
its fiduciary  duties that such  recommendation  should not be made or should be
withdrawn,  recommend to the shareholders of IBSF the approval of this Agreement
and the transactions  contemplated hereby and use its reasonable best efforts to
obtain,  as promptly as  practicable,  such  approval,  and (iii)  cooperate and
consult with HUBCO with respect to each of the foregoing matters.

                  If it becomes  necessary under Nasdaq rules or applicable laws
to obtain HUBCO  shareholder  approval,  HUBCO shall take all steps necessary to
obtain the approval of its  shareholders as promptly as possible.  In connection
therewith,  HUBCO shall (i) take all steps  necessary to duly call,  give notice
and convene a meeting of its shareholders for such purpose,  and (ii) subject to
the  right not to make a  recommendation  or to  withdraw  a  recommendation  if
HUBCO's Board of Directors,  after  consulting  with counsel,  determines in the
exercise of its fiduciary duties that such recommendation  should not be made or
should be withdrawn, recommend to the shareholders of HUBCO the approval of this
Agreement and the transactions  contemplated  hereby and use its reasonable best
efforts to obtain, as promptly as practicable, such approval.

                  5.8.  Further Assurances.

                  (a) Subject to the terms and conditions herein provided,  each
of the parties  hereto  agrees to use its  reasonable  best efforts to take,  or
cause to be  taken,  all  action  and to do,  or cause  to be done,  all  things
necessary,  proper or advisable under applicable laws and regulations to satisfy
the conditions to Closing and to consummate and make effective the  transactions
contemplated by this Agreement,  including, without limitation, using reasonable
efforts to lift or rescind any  injunction or  restraining  order or other order
adversely  affecting the ability of the parties to consummate  the  transactions
contemplated  by this Agreement and using its reasonable best efforts to prevent
the breach of any representation,  warranty, covenant or agreement of such party
contained or referred to in this  Agreement and to promptly  remedy the same. In
case at any time after the  Effective  Time any further  action is  necessary or
desirable to carry out the purposes of this  Agreement,  the proper officers and
directors of each party to this Agreement shall take all such necessary  action.
Nothing in this section  shall be construed to require any party to  participate
in any threatened or actual legal,  administrative or other  proceedings  (other
than proceedings, actions or investigations to which it is a party or subject or
threatened to be made a party or subject) in connection with consummation of the
transactions  contemplated by this Agreement  unless such party shall consent in
advance  and in  writing to such  participation  and the other  party  agrees to
reimburse and indemnify such party for and against any and all costs and damages
related thereto if the Merger is not consummated.

                  (b) HUBCO  agrees that from the date  hereof to the  Effective
Time,  except as  otherwise  approved  by IBSF in  writing  or as  permitted  or
required  by this  Agreement,  HUBCO  will use  reasonable  business  efforts to
maintain and  preserve  intact its business  organization,  properties,  leases,
employees and advantageous business relationships,  and HUBCO will not, nor will
it permit any HUBCO Subsidiary to, take any action: (i) that would result in any
of its representations and warranties  contained in Article IV of this Agreement
not being  true and  correct  in any  material  respect  at,  or prior  to,  the
Effective Time, or (ii) that would cause any of its conditions to Closing not to
be  satisfied,  or (iii)  that  would  constitute  a breach  or  default  of its
obligations under this Agreement, or (iv) to declare, set aside, make or pay any
extraordinary  cash dividend in excess of $0.40 per share of HUBCO Common Stock,
or (v) to enter into any agreement  after the date hereof with respect to one or
more  acquisitions  that,  individually  or in the aggregate,  can reasonably be
expected to materially  adversely  affect the ability of HUBCO to consummate the
Merger prior to the Cutoff Date (as such term is hereinafter  defined),  or (vi)
to agree to do any of the foregoing.

                  (c)  HUBCO,  the  Bank,  IBSF  and the  Association  will  use
reasonable efforts to cause the Merger to occur on or before October 31, 1998.

                  5.9. Public Announcements. HUBCO and IBSF shall cooperate with
each other in the  development  and  distribution of all news releases and other
public  filings and  disclosures  with  respect to this  Agreement or the Merger
transactions  contemplated hereby, and HUBCO and IBSF agree that unless approved
mutually  by them in advance,  they will not issue any press  release or written
statement  for  general  circulation  relating  primarily  to  the  transactions
contemplated  hereby,  except as may be otherwise  required by law or regulation
upon the advice of counsel.

                  5.10. Failure to Fulfill  Conditions.  In the event that HUBCO
or IBSF determines that a material condition to its obligation to consummate the
transactions contemplated hereby cannot be fulfilled on or prior to December 31,
1998 (the  "Cutoff  Date")  and that it will not waive that  condition,  it will
promptly  notify  the  other  party.   Except  for  any  acquisition  or  merger
discussions  HUBCO  may enter  into  with  other  parties,  IBSF and HUBCO  will
promptly   inform  the  other  of  any  facts   applicable  to  IBSF  or  HUBCO,
respectively, or their respective directors or officers, that would be likely to
prevent or materially delay approval of the Merger by any Governmental Entity or
which would otherwise prevent or materially delay completion of the Merger.

                  5.11.    Employee Matters.

                  (a) Following  consummation  of the Merger,  HUBCO agrees with
IBSF to honor the existing  written  employment  and  severance  contracts  with
officers  and  employees of IBSF and  Association  that are included in the IBSF
Disclosure Schedule.

                  (b) Following consummation of the Merger, the Bank will decide
whether to continue each of the  Association  and/or IBSF's  pension and welfare
plans for the benefit of employees of the  Association and IBSF, or to have such
employees  become  covered  under a HUBCO  Pension  and Welfare  Plan.  If HUBCO
decides  to cover  Association  and IBSF  employees  under a HUBCO  Pension  and
Welfare Plan, such employees will receive credit for prior years of service with
the  Association  and/or  IBSF  for  purposes  of  determining   eligibility  to
participate,  and vesting, if applicable. No prior existing condition limitation
shall be imposed  with respect to any medical  coverage  plan as a result of the
Merger.

                  (c) Any person who was  serving as an  employee of either IBSF
or the  Association  immediately  prior to the Effective  Time (other than those
employees covered by either a written  employment  agreement or the arrangements
set forth in Section 5.11 of the IBSF Disclosure  Schedule) whose  employment is
discontinued  by HUBCO or the Bank or any of the HUBCO  Subsidiaries  within six
months after the Effective Time (unless  termination  of such  employment is for
Cause (as defined below)) shall be entitled to a severance payment from the Bank
equal in amount to one  week's  base pay for each  full year such  employee  was
employed by IBSF or the  Association or any successor or predecessor  thereto or
other  IBSF  Subsidiary,  subject to a minimum  of two  weeks'  severance  and a
maximum of 25 weeks'  severance,  together with any accrued but unused  vacation
leave  with  respect  to the  calendar  year in which  termination  occurs.  For
purposes of this Section  5.11,  "Cause" shall mean  termination  because of the
employee's personal  dishonesty,  incompetence,  willful  misconduct,  breach of
fiduciary duty involving personal profit,  intentional failure to perform stated
duties or willful  violation of any law, rule, or regulation (other than traffic
violations  or similar  offenses).  Following  the  expiration  of the foregoing
severance policy,  any years of service  recognized for purposes of this Section
5.11(c) will be taken into account under the terms of any  applicable  severance
policy of HUBCO.

                  (d)(i) Each  participant in the IBS Financial  Corp.  Employee
Stock Ownership Plan ("IBSF ESOP") not fully vested will, in accordance with the
terms of the IBSF ESOP,  become  fully vested in his or her IBSF ESOP account as
of the  Effective  Time.  As soon as  practicable  after the  execution  of this
Agreement, IBSF, the Association and HUBCO will cooperate to cause the IBSF ESOP
to be amended and other action taken, in a manner reasonably  acceptable to IBSF
and HUBCO, to provide that the IBSF ESOP will terminate upon the Effective Time.
Between  the  date  hereof  and the  Effective  Time,  the  existing  IBSF  ESOP
indebtedness  shall be paid in the ordinary  course of business  pursuant to the
existing loan amortization  schedule and IBSF or the Association shall make such
contributions  to the  IBSF  ESOP  as  necessary  to  fund  such  payments.  Any
indebtedness of the IBSF ESOP remaining as of the Effective Time shall be repaid
from the Trust associated with the IBSF ESOP through  application or sale of the
HUBCO Common Stock received by the IBSF ESOP;  provided,  however,  that (A) any
related  sale or  distribution  of shares by the IBSF ESOP shall be  effected in
accordance with the  requirements of federal and any applicable state securities
laws and  regulations,  including any rules of the NASD, (B) any related sale or
distribution of shares by the IBSF ESOP and any participant shall be effected in
such a manner (and with such  safeguards as may be necessary or  appropriate) so
as not to jeopardize the intended "pooling of interests" accounting treatment of
the Merger,  and (C) all  distributions  from the IBSF ESOP after the  Effective
Time shall be in shares of HUBCO Common  Stock.  Upon the  repayment of the IBSF
ESOP  loan,  the  remaining  funds in the IBSF  ESOP  suspense  account  will be
allocated (to the extent permitted by Sections  401(a),  415 or 4975 of the Code
and the applicable  laws and  regulations  including,  without  limitation,  the
applicable  provisions of ERISA) to IBSF ESOP  participants (as determined under
the  terms  of the IBSF  ESOP).  IBSF  and  HUBCO  agree  that,  subject  to the
conditions described herein, as soon as practicable after the Effective Time and
repayment of the IBSF ESOP loan, participants in the IBSF ESOP shall be entitled
at their  election  to have the  amounts  in their  IBSF  ESOP  accounts  either
distributed to them in a lump sum or rolled over to another  tax-qualified  plan
(including  HUBCO or Bank plans to the extent  permitted by HUBCO) or individual
retirement account.

                  (ii) The actions relating to termination of the IBSF ESOP will
be adopted  conditioned upon the consummation of the Merger and upon receiving a
favorable  determination  letter from the Internal  Revenue Service ("IRS") with
regard  to the  continued  qualification  of the IBSF ESOP  after  any  required
amendments. IBSF and HUBCO will cooperate in submitting appropriate requests for
any such determination letter to the IRS and will use their best efforts to seek
the issuance of such letter as soon as  practicable  following  the date hereof.
IBSF and HUBCO will adopt such additional  amendments to the IBSF ESOP as may be
reasonably  required by the IRS as a condition  to granting  such  determination
letter,  provided that such amendments do not (A) substantially change the terms
outlined herein,  (B) have a Material Adverse Change on IBSF or (C) result in an
additional material liability to HUBCO.

                  (iii) As of and  following  the  Effective  Time,  HUBCO shall
cause the IBSF ESOP to be maintained for the exclusive  benefit of employees and
other  persons  who were  participants  or  beneficiaries  therein  prior to the
Effective   Time  and  proceed  with   termination  of  the  IBSF  ESOP  through
distribution  of  its  assets  in  accordance  with  its  terms  subject  to the
amendments  described  herein and as  otherwise  may be  required to comply with
applicable  law or to obtain a  favorable  determination  from the IRS as to the
continuing  qualified status of the IBSF ESOP, provided,  however,  that no such
termination  distributions of the IBSF ESOP shall occur after the Effective Time
until a favorable  termination letter has been received from the IRS. IBSF shall
cause  the IBSF ESOP to be  amended,  effective  as of the  Effective  Time,  to
provide  that  the  administrative  committee  thereof  shall  consist  of  four
individuals,  two of whom are  appointed by the Board of Directors of IBSF prior
to the Effective Time (the  appointment of such  individuals  will be subject to
the prior consent of HUBCO, and such individuals after their appointment may not
be  unreasonably  removed or changed by HUBCO or its  affiliates for a period of
two years after the Effective  Time),  and two of whom are appointed by HUBCO as
of the Effective Time.).

                  (e) As of and following the Effective Time,  HUBCO shall cause
the Excess Benefit Plan of IBSF ("Excess Benefit Plan") to be maintained for the
exclusive  benefit of its sole  participant  until the participant  receives his
termination  distribution from the IBSF ESOP at which time HUBCO shall cause the
Excess Benefit Plan to distribute  amounts credited to his account in accordance
with the terms of the Excess Benefit Plan.

                  (f) Employees of IBSF and the Association who become employees
of HUBCO or any HUBCO Subsidiary shall become entitled to participate in HUBCO's
defined benefit pension plan in accordance with its terms. In this regard,  each
such employee shall (i) receive, for purposes of participation and vesting only,
credit for all  service  with IBSF or the  Association  and (ii) enter the HUBCO
defined benefit pension plan on the entry date concurrent with or next following
the employee's satisfaction of such plan's minimum participation requirements.

                  (g) Employees of IBSF and the Association who become employees
of HUBCO or any HUBCO  Subsidiary  shall become  entitled to  participate in the
applicable HUBCO retirement  savings plan ("401(k) Plan") in accordance with its
terms.  In this regard,  each such employee  shall (i) receive,  for purposes of
participation  and  vesting  only,  credit  for  all  service  with  IBSF or the
Association,  and (ii)  enter  the  applicable  401(k)  Plan on the  entry  date
concurrent  with or next  following the employee's  satisfaction  of such plan's
minimum participation requirements.

                  (h) Each  participant  in the IBSF  Recognition  and Retention
Plan  ("RRP") not fully vested will,  in  accordance  with the terms of the RRP,
become fully vested in Plan Share Awards thereunder as of the Effective Time. As
soon as practicable after the execution of this Agreement, IBSF, the Association
and HUBCO will  cooperate to cause the RRP to be amended and other action taken,
in a manner  reasonably  acceptable  to IBSF and HUBCO,  to provide that the RRP
will  terminate  upon  the  Effective  Time;  provided,  however,  that  (A) any
distribution  of shares under the RRP shall be effected in  accordance  with the
requirements,  if any, of federal and state securities laws and regulations, (B)
any distribution of shares under the RRP shall be effected in such a manner (and
with such safeguards as may be necessary or appropriate) so as not to jeopardize
the intended "pooling of interests"  accounting treatment of the Merger, and (C)
all  distributions  from the RRP after the Effective  Time shall be in shares of
HUBCO Common  Stock.  No action shall be taken that would  adversely  affect the
rights of plan  participants who hold outstanding  grants or awards of shares of
IBSF Common Stock, whether before or after the Effective Time. No further grants
or awards shall be made under the RRP following the date of this Agreement.

                  (i) IBSF and the  Association  may continue to administer such
bonus  programs and  arrangements  as are disclosed  pursuant to this  Agreement
through  the  Effective  Time,  with  such  equitable  modifications  as  may be
appropriate to take into account the  circumstances of the Merger and the timing
thereof.  In the event the Merger  shall  occur  prior to the end of the current
fiscal year,  bonuses  shall be provided on a pro rata basis with respect to the
interim period; provided,  however, that bonuses for such interim period, in the
aggregate, shall not exceed $50,000.

                  (j) Within  ninety (90) days after the date hereof,  HUBCO and
the Bank shall use their reasonable best efforts to inform the employees of IBSF
and the  Association  of the  likelihood  of  such  employees  having  continued
employment  with HUBCO or a HUBCO  Subsidiary  following the Effective Time and,
where appropriate, shall use their reasonable best efforts to interview the IBSF
and  Association  employees  to  determine  if  there  are  mutually  beneficial
employment  opportunities  available at HUBCO or a HUBCO  Subsidiary.  It is the
intent  of HUBCO  and the  Bank in  connection  with  reviewing  applicants  for
employment positions to give any IBSF and Association employee who is terminated
for other than Cause within six (6) months following the Effective Time the same
consideration as is afforded the Bank employees for such positions in accordance
with  existing  formal or  informal  polices for a period of six (6) months from
such date of termination.

                  (k) Each  employee of IBSF or the  Association  identified  in
Section  5.11 of the IBSF  Disclosure  Schedule  shall be  entitled to receive a
"retention"  bonus  from  IBSF or the  Association  in the  amount  set forth in
Section  5.11 of the IBSF  Disclosure  Schedule in the event that such  employee
remains  an  employee  of IBSF  or the  Association,  as  applicable  until  the
Effective  Time (or in certain  cases,  the date the systems  conversion  occurs
after  the  Effective   Time)  and   satisfactorily   fulfills  the  duties  and
responsibilities of the position of such employee of IBSF or the Association, as
the case may be, through the Effective Time; provided that retention bonuses, in
the aggregate, shall not exceed $150,000.

                  (l) HUBCO  shall pay the cost of  out-placement  services  for
employees who are terminated  without Cause in connection with the Merger within
six (6) months after the Effective Time. HUBCO shall not be obligated to pay any
out-placement  fees in connection with the foregoing or more than $25,000 in the
aggregate for such services.

                  5.12. Disclosure  Supplements.  From time to time prior to the
Effective Time, each party hereto will promptly  supplement or amend (by written
notice to the other) its  respective  Disclosure  Schedules  delivered  pursuant
hereto  with  respect  to any  matter  hereafter  arising  which,  if  existing,
occurring or known at the date of this Agreement, would have been required to be
set forth or  described  in such  Schedules or which is necessary to correct any
information  in such  Schedules  which has been rendered  materially  inaccurate
thereby. For the purpose of determining satisfaction of the conditions set forth
in Article VI and  subject to  Sections  6.2(a) and  6.3(a),  no  supplement  or
amendment to the parties'  respective  Disclosure  Schedules  which corrects any
representation  or warranty which was untrue when made shall eliminate the other
party's right (if any) to terminate this Agreement based on the original untruth
of the  representation  or  warranty;  provided,  that the other  party shall be
deemed to have waived such right if it does not  exercise  such right  within 15
days after receiving the correcting supplement or amendment.

                  5.13.  Transaction Expenses of IBSF.

                  (a) For planning purposes, IBSF shall, within 30 days from the
date hereof,  provide  HUBCO with its  estimated  budget of  transaction-related
expenses  reasonably  anticipated to be payable by IBSF in connection  with this
transaction based on facts and circumstances then currently known, including the
fees  and  expenses  of  counsel,  accountants,  investment  bankers  and  other
professionals. IBSF shall promptly notify HUBCO if or when it determines that it
will expect to exceed its budget.

                  (b) Promptly after the execution of this Agreement, IBSF shall
ask all of its attorneys and other  professionals  to render current and correct
invoices for all unbilled time and  disbursements.  IBSF shall accrue and/or pay
all of such amounts as soon as possible.

                  (c) IBSF  shall  cause its  professionals  to  render  monthly
invoices  within 15 days after the end of each month.  IBSF shall  advise  HUBCO
monthly of all out-of-pocket expenses which IBSF has incurred in connection with
this transaction.

                  (d) HUBCO, in reasonable  consultation  with IBSF,  shall make
all  arrangements  with  respect  to the  printing  and  mailing  of  the  Proxy
Statement-Prospectus.

                  5.14       Indemnification.

                  (a) For a period of six years after the Effective Time,  HUBCO
shall indemnify, defend and hold harmless each person who is now, or has been at
any time prior to the date hereof or who becomes prior to the Effective  Time, a
director, officer, employee or agent of IBSF or the Association or serves or has
served at the request of IBSF or the  Association in any capacity with any other
person (collectively,  the "Indemnitees")  against any and all claims,  damages,
liabilities,  losses, costs, charges,  expenses (including,  without limitation,
reasonable costs of investigation,  and the reasonable fees and disbursements of
legal  counsel and other  advisers and experts as incurred),  judgments,  fines,
penalties  and amounts  paid in  settlement,  asserted  against,  incurred by or
imposed  upon any  Indemnitee  by  reason of the fact that he or she is or was a
director, officer, employee or agent of IBSF or the Association or serves or has
served at the request of IBSF or the  Association in any capacity with any other
person,  in connection  with,  arising out of or relating to (i) any threatened,
pending or completed claim, action, suit or proceeding (whether civil, criminal,
administrative or investigative),  including,  without  limitation,  any and all
claims, actions,  suits,  proceedings or investigations by or on behalf of or in
the  right of or  against  IBSF or the  Association  or any of their  respective
affiliates,  or by any former or present shareholder of IBSF (each a "Claim" and
collectively, "Claims"), including, without limitation, any Claim which is based
upon,  arises  out  of  or  in  any  way  relates  to  the  Merger,   the  Proxy
Statement/Prospectus,  this Agreement,  any of the transactions  contemplated by
this Agreement,  the Indemnitee's  service as a member of the Board of Directors
of IBSF or the  Association  or of any committee of IBSF's or the  Association's
Board of Directors,  the events  leading up to the execution of this  Agreement,
any statement,  recommendation or solicitation  made in connection  therewith or
related  thereto  and any  breach  of any  duty in  connection  with  any of the
foregoing, or (ii) the enforcement of the obligations of HUBCO set forth in this
Section 5.14, in each case to the fullest  extent which IBSF or the  Association
would  have  been  permitted  under  any  applicable  law and  their  respective
Certificates of  Incorporation  or Bylaws had the Merger not occurred (and HUBCO
shall also  advance  expenses as incurred to the fullest  extent so  permitted).
Notwithstanding the foregoing,  but subject to subsection (b) below, HUBCO shall
not provide any  indemnification  or advance any  expenses  with  respect to any
Claim  which  relates to a personal  benefit  improperly  paid or  provided,  or
alleged to have been improperly paid or provided,  to the Indemnitee,  but HUBCO
shall reimburse the Indemnitee for costs incurred by the Indemnitee with respect
to such Claim when and if a court of  competent  jurisdiction  shall  ultimately
determine,  and such  determination  shall have become final and  nonappealable,
that the  Indemnitee  was not  improperly  paid or  provided  with the  personal
benefit alleged in the Claim.

                  (b) From and after the Effective Time,  HUBCO shall assume and
honor  any  obligation  of  IBSF or the  Association  immediately  prior  to the
Effective Time with respect to the  indemnification  of the Indemnitees  arising
out of the Certificate of Incorporation or Bylaws of IBSF or the Association, or
arising out of any written  indemnification  agreements  between IBSF and/or the
Association and such persons  disclosed in the IBSF Disclosure  Schedule,  as if
such  obligations  were pursuant to a contract or arrangement  between HUBCO and
such Indemnitees.

                  (c) In the event HUBCO or any of its successors or assigns (i)
reorganizes or consolidates  with or merges into or enters into another business
combination  transaction  with  any  other  person  or  entity  and is  not  the
resulting,  continuing or surviving corporation or entity of such consolidation,
merger  or  transaction,  or (ii)  liquidates,  dissolves  or  transfers  all or
substantially  all of its properties  and assets to any person or entity,  then,
and in each such case, proper provision shall be made so that the successors and
assigns of HUBCO assume the obligations set forth in this Section 5.14.

                  (d) HUBCO shall cause  IBSF's and the  Association's  officers
and directors to be covered under HUBCO's then current  officers' and directors'
liability  insurance  policy for a period of six years after the Effective Time,
or, in the  alternative,  to be  covered  under an  extension  of IBSF's and the
Association's  existing  officers' and directors'  liability  insurance  policy.
However,  HUBCO shall only be required to insure such persons upon terms and for
coverages  substantially  similar  to  IBSF's  and  the  Association's  existing
officers' and directors' liability insurance.

                  (e) Any Indemnitee wishing to claim indemnification under this
Section 5.14 shall  promptly  notify HUBCO upon  learning of any Claim,  but the
failure to so notify  shall not relieve  HUBCO of any  liability  it may have to
such  Indemnitee if such failure does not  materially  prejudice  HUBCO.  In the
event of any Claim (whether  arising  before or after the Effective  Time) as to
which  indemnification  under this Section 5.14 is  applicable,  (x) HUBCO shall
have the right to assume the  defense  thereof  and HUBCO shall not be liable to
such  Indemnitees  for any legal expenses of other counsel or any other expenses
subsequently incurred by such Indemnitee in connection with the defense thereof,
except  that if HUBCO  elects not to assume  such  defense,  or counsel  for the
Indemnitees  advises  that there are issues  which raise  conflicts  of interest
between  HUBCO  and  the   Indemnitees,   the  Indemnitees  may  retain  counsel
satisfactory  to them, and HUBCO shall pay the  reasonable  fees and expenses of
such counsel for the Indemnitees as statements therefor are received;  provided,
however,  that HUBCO shall be obligated  pursuant to this Section 5.14(e) to pay
for  only one firm of  counsel  for all  Indemnitees  in any  jurisdiction  with
respect to a matter unless the use of one counsel for multiple Indemnitees would
present such counsel with a conflict of interest that is not waived, and (y) the
Indemnitees will cooperate in the defense of any such matter. HUBCO shall not be
liable for settlement of any claim,  action or proceeding  hereunder unless such
settlement is effected with its prior written consent.  Notwithstanding anything
to the  contrary  in this  Section  5.14,  HUBCO  shall not have any  obligation
hereunder to any Indemnitee when and if a court of competent  jurisdiction shall
ultimately  determine,  and such  determination  shall  have  become  final  and
nonappealable,  that  the  indemnification  of  such  Indemnitee  in the  manner
contemplated hereby is prohibited by applicable law or public policy.

                  5.15 Bank Policies and Bank Merger.  Notwithstanding that IBSF
believes  that it has  established  all  reserves and taken all  provisions  for
possible  loan  losses  required  by  GAAP  and  applicable   laws,   rules  and
regulations, IBSF recognizes that HUBCO may have adopted different loan, accrual
and reserve policies (including loan  classifications and levels of reserves for
possible  loan  losses).  From  and  after  the  date of this  Agreement  to the
Effective  Time and in order to formulate the plan of  integration  for the Bank
Merger,  IBSF and HUBCO shall consult and cooperate with each other with respect
to (i)  conforming  to the extent  appropriate,  based  upon such  consultation,
IBSF's  loan,  accrual  and  reserve  policies  and IBSF's  other  policies  and
procedures regarding applicable regulatory matters, including without limitation
Federal  Reserve,  the Bank Secrecy Act and FDIC matters,  to those  policies of
HUBCO as HUBCO may  reasonably  identify  to IBSF  from  time to time,  (ii) new
extensions of credit or material  revisions to existing  terms of credits by the
Association,  in each case where the aggregate  exposure exceeds  $500,000,  and
(iii)  conforming,  based  upon  such  consultation,   the  composition  of  the
investment portfolio and overall asset/liability management position of IBSF and
the Association to the extent appropriate;  provided that any required change in
IBSF's practices in connection with the matters described in clause (i) or (iii)
above need not be effected (A) more than five days prior to the  Effective  Time
and (B) unless and until HUBCO agrees in writing that all  conditions  precedent
to the  Determination  Date have  occurred  and HUBCO has  provided  the Closing
Notice.  No accrual or reserve made by IBSF or any IBSF  Subsidiary  pursuant to
this subsection,  or any litigation or regulatory  proceeding arising out of any
such  accrual  or  reserve,  shall  constitute  or be  deemed  to be a breach or
violation  of  any  representation,   warranty,  covenant,  condition  or  other
provision of this  Agreement or to  constitute  a  termination  event within the
meaning of Section 7.1(d) or Section 7.1(g) hereof.

                  5.16       [Reserved]

                  5.17 Pooling and Tax-Free Reorganization Treatment. Before the
Effective Time, neither HUBCO nor IBSF shall  intentionally  take, fail to take,
or cause to be taken or not taken any action  within its  control,  which  would
disqualify the Merger as a "pooling-of-interests"  for accounting purposes or as
a "reorganization"  within the meaning of Section 368(a) of the Code. Subsequent
to the  Effective  Time,  HUBCO  shall  not take and shall  cause the  Surviving
Corporation  not to take any action within their  control that would  disqualify
the Merger as such a "reorganization" under the Code.

                  5.18 Comfort Letters.  HUBCO shall cause Arthur Andersen,  its
independent  public  accountants,  to deliver to IBSF, and IBSF shall cause D&T,
its independent public accountants,  to deliver to HUBCO and to its officers and
directors who sign the Registration Statement for this transaction, a short-form
"comfort  letter"  or "agreed  upon  procedures"  letter,  dated the date of the
mailing of the Proxy  Statement-Prospectus for the Shareholders Meeting of IBSF,
in the form customarily  issued by such accountants at such time in transactions
of this type.

                  5.19 Affiliates.  Promptly, but in any event within two weeks,
after the execution and delivery of this Agreement,  IBSF shall deliver to HUBCO
(a) a letter  identifying  all persons  who, to the  knowledge  of IBSF,  may be
deemed  to be  affiliates  of  IBSF  under  Rule  145 of the  1933  Act  and the
pooling-of-interests   accounting  rules,  including,  without  limitation,  all
directors and executive officers of IBSF and (b) use its reasonable best efforts
to cause each person who may be deemed to be an affiliate of IBSF to execute and
deliver  to  HUBCO a letter  agreement,  substantially  in the  form of  Exhibit
5.19-1, agreeing to comply with Rule 145 and to refrain from transferring shares
as required by the pooling-of-interests accounting rules. Within two weeks after
the date  hereof,  HUBCO  shall use its  reasonable  best  efforts  to cause its
directors and executive  officers to enter into letter agreements in the form of
Exhibit 5.19-2 with HUBCO concerning the pooling-of-interests  accounting rules.
HUBCO  hereby  agrees to  publish,  or file a Form  8-K,  Form 10-K or Form 10-Q
containing  financial results covering at least 30 days of post-Merger  combined
operations of HUBCO and IBSF as soon as practicable  (but in no event later than
30 days)  following the close of the first  calendar  month ending 30 days after
the Effective Time, in form and substance  sufficient to remove the restrictions
set forth in paragraph "B" of Exhibit 5.19-1.

                  5.20 Appointments. Joseph M. Ochman, Sr. shall be appointed as
a  director  of the  Surviving  Bank and  Chairman  of the  Southern  New Jersey
Advisory Council of the Surviving Bank at the Closing. Mr. Ochman will receive a
consulting  contract for services to be rendered during a transitional period on
terms  substantially  similar  to those set forth in  Section  5.20 of the HUBCO
Disclosure  Schedule,  with the form of the consulting contract to be reasonably
acceptable to HUBCO and Mr. Ochman.

                         ARTICLE VI - CLOSING CONDITIONS

                  6.1.   Conditions  to  Each  Party's  Obligations  Under  this
Agreement.  The  respective  obligations  of each party under this  Agreement to
consummate  the  Merger  shall  be  subject  to  the  satisfaction,   or,  where
permissible  under  applicable  law, waiver at or prior to the Effective Time of
the following conditions:

                  (a) Approval of Shareholders; SEC Registration. This Agreement
and the  transactions  contemplated  hereby  shall  have  been  approved  by the
requisite vote of the  shareholders  of IBSF and, if required,  by the requisite
vote of the shareholders of HUBCO. The HUBCO  Registration  Statement shall have
been  declared  effective by the SEC and shall not be subject to a stop order or
any threatened stop order, and the issuance of the HUBCO Common Stock shall have
been  qualified in every state where such  qualification  is required  under the
applicable state securities laws.

                  (b)   Regulatory   Filings.   All   necessary   regulatory  or
governmental  approvals and consents  (including without limitation any required
approval  of the  FDIC,  the  OTS,  the  Department,  the  FRB,  the SEC and (if
necessary) the DEP) required to consummate the transactions  contemplated hereby
shall  have  been  obtained  without  the  imposition  of  any  non-standard  or
non-customary  term or condition which would materially impair the value of IBSF
and the Association,  taken as a whole, to HUBCO. All conditions  required to be
satisfied  prior  to the  Effective  Time by the  terms  of such  approvals  and
consents shall have been satisfied; and all statutory waiting periods in respect
thereof  (including the  Hart-Scott-Rodino  waiting period if applicable)  shall
have expired.

                  (c) Suits and Proceedings.  No order, judgment or decree shall
be  outstanding  against a party  hereto or a third  party  that  would have the
effect  of  preventing  completion  of the  Merger;  no  suit,  action  or other
proceeding shall be pending or threatened by any Governmental Entity in which it
is sought to  restrain  or prohibit  the  Merger;  and no suit,  action or other
proceeding shall be pending before any court or Governmental  Entity in which it
is sought to  restrain  or  prohibit  the  Merger  or obtain  other  substantial
monetary or other relief against one or more parties  hereto in connection  with
this Agreement and which HUBCO or IBSF determines in good faith,  based upon the
advice of their  respective  counsel,  makes it  inadvisable to proceed with the
Merger because any such suit,  action or proceeding has a significant  potential
to be resolved in such a way as to deprive the party  electing not to proceed of
any of the material benefits to it of the Merger.

                  (d) Tax  Opinion.  HUBCO and IBSF shall each have  received an
opinion,  dated as of the  Effective  Time,  of  Pitney,  Hardin,  Kipp & Szuch,
reasonably  satisfactory  in form and  substance  to IBSF and its counsel and to
HUBCO, based upon  representation  letters reasonably  required by such counsel,
dated  on or  about  the  date  of  such  opinion,  and  such  other  facts  and
representations  as such counsel may  reasonably  deem  relevant,  to the effect
that:  (i) the Merger  will be treated  for  federal  income tax  purposes  as a
reorganization  qualifying under the provisions of Section 368 of the Code; (ii)
no gain or loss  will be  recognized  by  IBSF;  (iii)  no gain or loss  will be
recognized  by the IBSF  shareholders  upon the  exchange of IBSF  Common  Stock
solely for HUBCO  Common  Stock;  (iv) the tax basis of any HUBCO  Common  Stock
received  in  exchange  for IBSF  Common  Stock  shall  equal  the  basis of the
recipient's IBSF Common Stock surrendered in the exchange, reduced by the amount
of cash  received,  if any, in the exchange,  and increased by the amount of the
gain recognized,  if any, in the exchange (whether  characterized as dividend or
capital  gain  income);  and (v) the holding  period for any HUBCO  Common Stock
received in exchange for IBSF Common Stock will include the period  during which
IBSF Common Stock surrendered in the exchange was held,  provided such stock was
held as a capital asset on the date of the exchange.

                  (e) Pooling of Interests.  HUBCO shall have received a letter,
dated the  Closing  Date,  from its  accountants,  Arthur  Andersen,  reasonably
satisfactory  to HUBCO and IBSF,  to the effect that,  based on a review of this
Agreement and related  agreements and the facts and  circumstances  known to it,
the Merger shall be  qualified to be treated by HUBCO as a  pooling-of-interests
for accounting purposes.

                  6.2.  Conditions  to  the  Obligations  of  HUBCO  Under  this
Agreement.  The  obligations  of HUBCO  under  this  Agreement  shall be further
subject to the satisfaction or waiver, at or prior to the Effective Time, of the
following conditions:

                  (a) Representations and Warranties; Performance of Obligations
of IBSF and the Association.  Except for those representations which are made as
of a particular  date, the  representations  and warranties of IBSF contained in
this Agreement shall be true and correct in all material respects on the Closing
Date as though made on and as of the Closing  Date,  except to the extent waived
pursuant to Section  5.12  hereof.  IBSF shall have  performed  in all  material
respects the  agreements,  covenants and obligations to be performed by it prior
to the Closing Date. With respect to any  representation or warranty which as of
the Closing Date has required a supplement  or amendment to the IBSF  Disclosure
Schedule  to render  such  representation  or  warranty  true and correct in all
material respects as of the Closing Date, the  representation and warranty shall
be deemed true and correct as of the  Closing  Date only if (i) the  information
contained in the supplement or amendment to the Disclosure  Schedule  related to
events  occurring  following the execution of this  Agreement and (ii) the facts
disclosed in such  supplement or amendment  would not either alone,  or together
with any  other  supplements  or  amendments  to the IBSF  Disclosure  Schedule,
materially  adversely  affect the  representation  as to which the supplement or
amendment relates.

                  (b) Opinion of Counsel.  HUBCO shall have  received an opinion
of counsel to IBSF,  dated the Closing Date,  in form and  substance  reasonably
satisfactory to HUBCO,  substantially to the effect set forth in accordance with
Exhibit 6.2(b) hereto.

                  (c)  Certificates.  IBSF shall have furnished  HUBCO with such
certificates of its officers or other  documents to evidence  fulfillment of the
conditions set forth in this Section 6.2 as HUBCO may reasonably request.

                  (d) Legal Fees.  IBSF shall have furnished  HUBCO with letters
from  all  attorneys  representing  IBSF  and  the  Association  in any  matters
confirming  that all  material  legal  fees have been paid in full for  services
rendered as of the Effective Time.

                  (e) Merger  Related  Expense.  IBSF shall have provided  HUBCO
with an accounting  of all merger  related  expenses  incurred by it through the
Closing Date,  including a good faith estimate of such expenses  incurred but as
to which  invoices have not been  submitted as of the Closing  Date.  The merger
related  expenses of IBSF,  other than printing  expenses  (which are within the
control of HUBCO), shall be reasonable, taking into account normal and customary
billing rates, fees and expenses for similar transactions.

                  6.3.   Conditions  to  the  Obligations  of  IBSF  Under  this
Agreement. The obligations of IBSF under this Agreement shall be further subject
to the  satisfaction  or  waiver,  at or prior  to the  Effective  Time,  of the
following conditions:

                  (a) Representations and Warranties; Performance of Obligations
of HUBCO.  Except for those  representations  which are made as of a  particular
date, the  representations  and warranties of HUBCO  contained in this Agreement
shall be true and correct in all material respects on the Closing Date as though
made on and as of the  Closing  Date,  except to the extent  waived  pursuant to
Section 5.12  hereof.  HUBCO shall have  performed in all material  respects the
agreements, covenants and obligations to be performed by it prior to the Closing
Date.  With respect to any  representation  or warranty  which as of the Closing
Date has required a supplement or amendment to the HUBCO Disclosure  Schedule to
render such representation or warranty true and correct in all material respects
as of the Closing Date, the representation and warranty shall be deemed true and
correct as of the  Closing  Date only if (i) the  information  contained  in the
supplement or amendment to the Disclosure  Schedule  related to events occurring
following the execution of this  Agreement and (ii) the facts  disclosed in such
supplement  or  amendment  would not either  alone,  or together  with any other
supplements or amendments to the HUBCO Disclosure Schedule, materially adversely
affect the representation as to which the supplement or amendment relates.

                  (b) Opinion of Counsel to HUBCO.  IBSF shall have  received an
opinion of counsel  to HUBCO,  dated the  Closing  Date,  in form and  substance
reasonably  satisfactory  to IBSF,  substantially  to the  effect  set  forth in
accordance with Exhibit 6.3(b) hereto.

                  (c) Fairness Opinion. IBSF shall have received an opinion from
Ryan,  Beck,  dated  no more  than  three  days  prior  to the  date  the  Proxy
Statement-Prospectus  is mailed to IBSF's  shareholders  (and if it shall become
necessary to resolicit proxies  thereafter,  dated no more than three days prior
to the date of any substantive amendment to the Proxy Statement-Prospectus),  to
the effect that, in its opinion, the consideration to be paid to shareholders of
IBSF  hereunder  is fair to such  shareholders  from a  financial  point of view
("Fairness Opinion").

                  (d)  Certificates.  HUBCO shall have  furnished IBSF with such
certificates of its officers and such other documents to evidence fulfillment of
the conditions set forth in this Section 6.3 as IBSF may reasonably request.

                  (e) Bank  Director  Appointment.  Joseph M. Ochman,  Sr. shall
have been  appointed  to the Board of  Directors of the Bank and shall have been
appointed  Chairman of the Southern New Jersey Advisory Council of the Surviving
Bank.

                 ARTICLE VII - TERMINATION, AMENDMENT AND WAIVER

                  7.1.  Termination.  This Agreement may be terminated  prior to
the Effective  Time,  whether  before or after approval of this Agreement by the
shareholders of IBSF:

                  (a)      by mutual written consent of the parties hereto;

                  (b) by HUBCO or IBSF (i) if the Effective  Time shall not have
occurred on or prior to the Cutoff  Date  unless the failure of such  occurrence
shall be due to the failure of the party seeking to terminate  this Agreement to
perform or observe its  agreements  set forth herein to be performed or observed
by  such  party  at or  before  the  Effective  Time,  or  (ii) if a vote of the
shareholders  of IBSF is  taken  and  such  shareholders  fail to  approve  this
Agreement at the meeting (or any adjournment or  postponement  thereof) held for
such  purpose  (provided  that the  terminating  party  shall not be in material
breach of any of its obligations  under Section 5.7 hereof),  or (iii) if a vote
of the shareholders of HUBCO is required by applicable  Nasdaq rules,  such vote
is taken and such shareholders fail to approve this Agreement at the meeting (or
any  adjournment or postponement  thereof) held for such purpose  (provided that
the terminating  party shall not be in material breach of any of its obligations
under Section 5.7 hereof);

                  (c) by HUBCO or IBSF upon  written  notice to the other if any
application for regulatory or governmental  approval necessary to consummate the
Merger and the other transactions  contemplated hereby shall have been denied or
withdrawn at the request or recommendation  of the applicable  regulatory agency
or  Governmental  Entity  or by HUBCO  upon  written  notice to IBSF if any such
application  is  approved  with  conditions  (other  than  conditions  which are
customary  or  standard in such  regulatory  approvals)  which would  materially
impair the value of IBSF and the Association, taken as a whole, to HUBCO;

                  (d) by HUBCO if (i) there shall have occurred an IBSF Material
Adverse  Change from that disclosed by IBSF in IBSF's  Quarterly  Report on Form
10-Q for the quarter  ended  December 31, 1997 (it being  understood  that those
matters  disclosed  in the IBSF  Disclosure  Schedule  shall  not be  deemed  to
constitute  such a material  adverse effect) or (ii) there was a material breach
in any  representation,  warranty,  covenant,  agreement or  obligation  of IBSF
hereunder  and such  breach  shall not have been  remedied  within 30 days after
receipt by IBSF of notice in writing from HUBCO to IBSF specifying the nature of
such breach and requesting that it be remedied;

                  (e) by IBSF, if (i) there shall have occurred a HUBCO Material
Adverse  Change from that  disclosed by HUBCO in HUBCO's  Annual  Report on Form
10-K for the year ended December 31, 1997, which change shall have resulted in a
material  adverse  effect on HUBCO  (it  being  understood  that  those  matters
disclosed in the HUBCO  Disclosure  Schedule  shall not be deemed to  constitute
such a material  adverse  effect);  or (ii)  there was a material  breach in any
representation,  warranty,  covenant, agreement or obligation of HUBCO hereunder
and such breach  shall not have been  remedied  within 30 days after  receipt by
HUBCO of notice in writing  from IBSF  specifying  the nature of such breach and
requesting that it be remedied;

                  (f) by IBSF, if IBSF's Board of Directors  shall have approved
an Acquisition Transaction after determining,  upon advice of counsel, that such
approval  was  necessary  in the  exercise of its  fiduciary  obligations  under
applicable laws;

                  (g) by HUBCO if the  conditions  set forth in Sections 6.1 and
6.2 are not satisfied and are not capable of being satisfied by the Cutoff Date;

                  (h) by IBSF if the  conditions  set forth in Sections  6.1 and
6.3 are not satisfied and are not capable of being satisfied by the Cutoff Date;
or

                  (i) by IBSF,  if (either  before or after the approval of this
Agreement by the shareholders of IBSF) its Board of Directors so determines by a
vote of a majority  of the members of its entire  Board,  at any time during the
five business day period  commencing with (and including) the first business day
following  the  Determination  Date,  if both of the  following  conditions  are
satisfied:

                           (1) the  Median  Pre-Closing  Price of  HUBCO  Common
Stock on the  Determination  Date is less than 85% of the Closing Price of HUBCO
Common Stock on the first Nasdaq trading day  immediately  following the date of
the first public  announcement  of the entry into this  Agreement (the "Starting
Date") (85% of HUBCO's  Starting Date Closing Price is referred to herein as the
"HUBCO Floor Price"); and

                           (2) (i) the quotient  obtained by dividing the Median
Pre-Closing  Price of HUBCO  Common Stock on the  Determination  Date by HUBCO's
Starting Date Closing  Price (the "HUBCO  Ratio") is less than (ii) the quotient
obtained by dividing the KBW 50 Index,  as published the following  business day
by  Bloomberg  or  other   reliable   source  (the  "Index  Price")  as  of  the
Determination  Date by the Index Price as of the Starting  Date and  subtracting
0.10 from the quotient in this clause  (2)(ii)  (such  number being  referred to
herein as the "Index Ratio").

Notwithstanding the foregoing,  if IBSF elects to exercise its termination right
pursuant to this  subsection  (i), it shall give prompt  written notice to HUBCO
(provided that such notice of election to terminate may be withdrawn at any time
within the aforementioned five business day period)).  During the three business
day period  commencing  with its  receipt of such  notice,  HUBCO shall have the
option of  increasing  the  consideration  to be received by the holders of IBSF
Common Stock  hereunder by increasing  the Exchange Ratio to equal the lesser of
(i) a number  (rounded to four decimals)  equal to a quotient,  the numerator of
which is the HUBCO  Floor Price  multiplied  by the  Exchange  Ratio (as then in
effect) and the  denominator of which is the Median  Pre-Closing  Price of HUBCO
Common Stock,  and (ii) a number (rounded to four decimals) equal to a quotient,
the numerator of which is the Index Ratio  multiplied by the Exchange  Ratio (as
then in effect) and the  denominator of which is the HUBCO Ratio. If HUBCO makes
an election  contemplated by the preceding sentence,  within such three business
day period, it shall give prompt written notice to IBSF of such election and the
revised Exchange Ratio, whereupon no termination shall have occurred pursuant to
this subsection (i) and this Agreement shall remain in effect in accordance with
its terms (except as the Exchange  Ratio shall have been so  modified),  and any
references in this Agreement to "Exchange  Ratio" shall  thereafter be deemed to
refer to the Exchange Ratio as adjusted pursuant to this subsection (i).

                  7.2.  Effect of  Termination.  In the event of the termination
and  abandonment  of this  Agreement by either HUBCO or IBSF pursuant to Section
7.1, this Agreement  (other than Section  5.5(b),  the  penultimate  sentence of
Section 5.6(h),  this Section 7.2 and Section 8.1) shall  forthwith  become void
and have no  effect,  without  any  liability  on the  part of any  party or its
officers,  directors or shareholders.  Nothing contained herein,  however, shall
relieve any party from any liability for any breach of this Agreement.

                  7.3. Amendment.  This Agreement may be amended by action taken
by the parties  hereto at any time before or after adoption of this Agreement by
the  shareholders  of IBSF but, after any such adoption,  no amendment  shall be
made which  reduces  the amount or changes the form of the  consideration  to be
delivered to the shareholders of IBSF without the approval of such shareholders.
This  Agreement may not be amended  except by an instrument in writing signed on
behalf of all the parties hereto.

                  7.4. Extension;  Waiver. The parties may, at any time prior to
the Effective Time of the Merger, (i) extend the time for the performance of any
of the  obligations  or other acts of the other parties  hereto;  (ii) waive any
inaccuracies in the  representations  and warranties  contained herein or in any
document delivered  pursuant thereto;  or (iii) waive compliance with any of the
agreements  or  conditions  contained  herein.  Any agreement on the part of any
party to any such  extension  or waiver  shall be valid  only if set forth in an
instrument in writing signed on behalf of such party against which the waiver is
sought to be enforced.

                          ARTICLE VIII - MISCELLANEOUS

                  8.1.  Expenses.

                  (a) Except as otherwise expressly stated herein, all costs and
expenses  incurred  in  connection  with  this  Agreement  and the  transactions
contemplated hereby (including legal, accounting and investment banking fees and
expenses)  shall  be borne by the  party  incurring  such  costs  and  expenses.
Notwithstanding the foregoing, IBSF may bear the expenses of the Association.

                  (b)  Notwithstanding  any  provision in this  Agreement to the
contrary, in the event that either of the parties shall willfully default in its
obligations hereunder,  the non-defaulting party may pursue any remedy available
at law or in equity to enforce  its  rights  and shall be paid by the  willfully
defaulting  party  for  all  damages,  costs  and  expenses,  including  without
limitation legal, accounting, investment banking and printing expenses, incurred
or  suffered  by the  non-defaulting  party  in  connection  herewith  or in the
enforcement of its rights hereunder.

                  8.2.  Survival.  The respective  representations,  warranties,
covenants and agreements of the parties to this Agreement  shall not survive the
Effective Time, but shall terminate as of the Effective Time, except for Article
II, this Section 8.2 and Sections 5.5(b), 5.8(a), 5.11 and 5.14.

                  Reference is made to the Agreement  and Plan of Merger,  dated

                  FORM OF AFFILIATE LETTER FOR IBSF AFFILIATES


                                                             _____________, 1998


HUBCO, Inc.
1000 MacArthur Boulevard
Mahwah, NJ 07430

Gentlemen:

                  I am  delivering  this  letter to you in  connection  with the
proposed acquisition (the "Merger") of IBS Financial Corp.  ("IBSF"),  by HUBCO,
Inc., a New Jersey  corporation and registered  bank holding company  ("HUBCO"),
pursuant  to the  Agreement  and Plan of Merger  dated as of March 31, 1998 (the
"Agreement") between IBSF, its thrift subsidiary, HUBCO and its bank subsidiary.
Capitalized  terms  used  herein and not  otherwise  defined  have the  meanings
assigned to them in the Agreement.  I currently own shares of IBSF Common Stock.
As a result  of the  Merger,  I will  receive  shares of HUBCO  Common  Stock in
exchange for my IBSF Common Stock.

                  I have been  advised  that as of the date of this letter I may
be deemed to be an "affiliate"  of IBSF, as the term  "affiliate" is defined for
purposes  of  paragraphs  (c) and (d) of Rule 145 of the rules  and  regulations
promulgated under the Securities Act of 1933, as amended (the "1933 Act") by the
Securities and Exchange  Commission  ("SEC") and as the term "affiliate" is used
for purposes of the SEC's rules and regulations  applicable to the determination
of  whether  a merger  can be  accounted  for as a  "pooling  of  interests"  as
specified  in the SEC's  Accounting  Series  Release  135,  as  amended by Staff
Accounting Bulletins Nos. 65 and 76 ("ASR 135").

                  I represent to and agree with HUBCO that:

                  A. Transfer Review  Restrictions.  During the period beginning
on the date hereof and ending 30 days prior to the consummation of the Merger, I
shall not sell, transfer, reduce my risk with respect to or otherwise dispose of
("transfer")  any IBSF  Common  Stock  owned by me,  and I shall not  permit any
relative who shares my home, or any person or entity who or which I control,  to
transfer any IBSF Common Stock owned by such person or entity, without notifying
HUBCO three  business  days in advance of the  proposed  transfer  (the  "Notice
Period") and giving HUBCO a reasonable opportunity to review the transfer before
it is  consummated.  HUBCO,  if  advised  to do so  by  its  independent  public
accountants  in writing a copy of which is provided to me, may instruct me prior
to the end of the Notice  Period not to make or permit the  transfer  because it
may interfere with the "pooling of interests"  treatment of the Merger.  I shall
abide by any such instructions.

                  B. Transfer  Restrictions During Merger Consummation Period. I
shall not transfer any IBSF Common Stock owned by me, and I shall not permit any
relative who shares my home, or any person or entity who or which I control,  to
transfer any IBSF Common Stock owned by such person or entity  during the period
beginning 30 days prior to the consummation of the Merger and ending immediately
after  financial  results  covering  at  least 30 days of  post-Merger  combined
operations  have been  published by HUBCO by means of the filing of a Form 10-Q,
Form 10-K or Form 8-K under the Securities Exchange Act of 1934, as amended, the
issuance of a quarterly  earnings  report,  or any other public  issuance  which
satisfies  the  requirements  of ASR 135, in each case except for  transfers  by
operation  of law,  by will or under the laws of descent and  distribution.  For
purposes of this paragraph only, "IBSF Common Stock" includes HUBCO Common Stock
as converted.  I understand that HUBCO has agreed to publish  financial  results
covering at least 30 days of post-Merger  combined  operations of HUBCO and IBSF
as soon as practicable  (but in no event later than 30 days) following the close
of the first calendar month ending 30 days after the Effective Time.

                  C.  Compliance  with Rule 145.  I have been  advised  that the
issuance of HUBCO Common  Stock to me pursuant to the Merger will be  registered
with the SEC  under  the  1933  Act on a  Registration  Statement  on Form  S-4.
However, I have also been advised that, since I may be deemed to be an affiliate
of IBSF at the time the Merger is submitted  for a vote of IBSF's  shareholders,
any  transfer  by  me of  HUBCO  Common  Stock  is  restricted  under  Rule  145
promulgated  by the SEC under the 1933 Act.  I agree not to  transfer  any HUBCO
Common Stock received by me or any of my affiliates  unless (i) such transfer is
made in conformity with the volume and other limitations of Rule 145 promulgated
by the SEC under the 1933 Act, (ii) in the opinion of HUBCO's counsel or counsel
reasonably   acceptable  to  HUBCO,  such  transfer  is  otherwise  exempt  from
registration  under the 1933 Act or (iii) such transfer is registered  under the
1933 Act.

                  D. Stop Transfer Instructions;  Legend on Certificates. I also
understand  and agree that stop transfer  instructions  will be given to HUBCO's
transfer agents with respect to the HUBCO Common Stock received by me and any of
my  affiliates  and that there will be placed on the  certificates  of the HUBCO
Common  Stock  issued  to me and  any  of my  affiliates,  or any  substitutions
therefor, a legend stating in substance:

                  "THE SHARES  REPRESENTED BY THIS  CERTIFICATE WERE ISSUED IN A
         TRANSACTION TO WHICH RULE 145  PROMULGATED  UNDER THE SECURITIES ACT OF
         1933 APPLIES.  THE SHARES  REPRESENTED BY THIS  CERTIFICATE MAY ONLY BE
         TRANSFERRED  IN ACCORDANCE  WITH THE TERMS OF AN AGREEMENT  DATED AS OF
         MARCH 31, 1998 BETWEEN THE REGISTERED HOLDER HEREOF AND HUBCO,  INC., A
         COPY OF WHICH  AGREEMENT IS ON FILE AT THE PRINCIPAL  OFFICES OF HUBCO,
         INC."

                  E.  Consultation  with  Counsel.  I have  carefully  read this
letter and the Agreement and discussed the  requirements  of such  documents and
other  applicable  limitations upon my ability to transfer HUBCO Common Stock to
the extent I felt necessary with my counsel or counsel for IBSF.

                  Execution of this letter is not an admission on my part that I
am an "affiliate"  of IBSF as described in the second  paragraph of this letter,
or a waiver of any  rights I may have to  object to any claim  that I am such an
affiliate  on or after the date of this  letter.  This  letter  shall  terminate
concurrently with any termination of the Agreement in accordance with its terms.

                                               Very truly yours,



                                               -----------------------------

HUBCO, Inc.
1000 MacArthur Boulevard
Mahwah, NJ 07430

Gentlemen:

                  I am  delivering  this  letter to you in  connection  with the
proposed  merger (the  "Merger") of IBS Financial  Corp.  ("IBSF") with and into
HUBCO,  Inc., a New Jersey  corporation  and  registered  bank  holding  company
("HUBCO"),  pursuant to the  Agreement  and Plan of Merger dated as of March 31,
1998 (the "Agreement")  between IBSF, its thrift subsidiary,  HUBCO and its bank
subsidiary. I currently own shares of HUBCO's common stock, no par value ("HUBCO
Common Stock").

                  I have been  advised  that as of the date of this letter I may
be deemed to be an  "affiliate"  of HUBCO,  as the term  "affiliate" is used for
purposes of the rules and regulations of the Securities and Exchange  Commission
(the "SEC") applicable to the determination of whether a merger can be accounted
for as a "pooling of  interests"  as  specified in the SEC's  Accounting  Series
Release 135, as amended by Staff Accounting Bulletins Nos.
65 and 76 ("ASR 135").

                  I represent and covenant with HUBCO and IBSF that:

                  A. Transfer Restrictions Prior to Merger Consummation.  During
the  period  beginning  on the  date  hereof  and  ending  30 days  prior to the
consummation  of the  Merger,  I shall not sell,  transfer,  reduce my risk with
respect to or otherwise  dispose of ("transfer") any HUBCO Common Stock owned by
me,  and I shall not permit any  relative  who shares my home,  or any person or
entity who or which I control, from transferring any HUBCO Common Stock owned by
such person or entity, without notifying HUBCO three business days in advance of
the  proposed  transfer  (the  "Notice  Period")  and giving  HUBCO a reasonable
opportunity  to object to the transfer  before it is  consummated.  HUBCO,  upon
advice of its independent public  accountants,  may instruct me prior to the end
of the Notice Period not to make or permit the transfer because it may interfere
with the "pooling of  interests"  treatment of the Merger.  I shall abide by any
such instructions.

                  B. Post-Consummation Transfer Restrictions.  During the period
beginning 30 days prior to the consummation of the Merger and ending immediately
after  financial  results  covering  at  least 30 days of  post-Merger  combined
operations  have  been  published  by HUBCO by means of filing of a Form 10-Q or
Form 8-K under the Securities  Exchange Act of 1934, the issuance of a quarterly
earnings  report,  or any other public issuance which satisfies the requirements
of ASR 135, I shall not transfer any HUBCO Common Stock owned by me, and I shall
not permit any relative who shares my home, or any person or entity who or which
I control, to transfer any HUBCO Common Stock owned by such person or entity, in
each case except for transfers by operation of law, by will or under the laws of
descent  and  distribution.  I  understand  that  HUBCO has  agreed  to  publish
financial results covering at least 30 days of post-Merger  combined  operations
of HUBCO and IBSF as soon as  practicable  (but in no event  later than 30 days)
following  the  close of the  first  calendar  month  ending  30 days  after the
Effective Time.

                  C.  Consultation  with  Counsel.  I have  carefully  read this
letter and the Agreement and discussed the  requirements  of such  documents and
other  applicable  limitations upon my ability to transfer HUBCO Common Stock to
the extent I felt necessary with my counsel or counsel for HUBCO.

                  Execution of this letter is not an admission on my part that I
am an "affiliate" of HUBCO as described in the second  paragraph of this letter,
or a waiver of any  rights I may have to  object to any claim  that I am such an
affiliate  on or after the date of this  letter.  This  letter  shall  terminate
concurrently with any termination of the Agreement in accordance with its terms.

                                    Very truly yours,

                       FORM OF OPINION OF COUNSEL TO IBSF
                 TO BE DELIVERED TO HUBCO ON THE EFFECTIVE TIME


                  (a) IBSF and the  Association  have  full  corporate  power to
carry out the  transactions  contemplated  in the  Agreement.  The execution and
delivery of the Agreement and the consummation of the transactions  contemplated
thereunder  have been duly and validly  authorized  by all  necessary  corporate
action on the part of IBSF and the Association,  and the Agreement constitutes a
valid and legally binding obligation of IBSF and the Association  enforceable in
accordance  with  its  terms,  except  as may  be  limited  by  (i)  bankruptcy,
insolvency, reorganization, moratorium, receivership, conservatorship, and other
laws now or hereafter  in effect  relating to or affecting  the  enforcement  of
creditors'  rights  generally or the rights of creditors of New Jersey chartered
savings  institutions  or  their  holding  companies,   (ii)  general  equitable
principles,  (iii)  laws  relating  to  the  safety  and  soundness  of  insured
depository institutions,  and (iv) implied covenants of good faith, fair dealing
and commercially  reasonable conduct and by applicable public policies and laws,
and except that no opinion need be rendered as to the effect or  availability of
equitable   remedies  or   injunctive   relief   (regardless   of  whether  such
enforceability  is considered  in a proceeding in equity or at law).  Subject to
satisfaction  of  the  conditions  set  forth  in  the  Agreement,  neither  the
transactions  contemplated  in the  Agreement,  nor  compliance  by IBSF and the
Association with any of the provisions thereof, will (i) conflict with or result
in a breach or default under (A) the certificate of  incorporation  or bylaws of
IBSF or the charter or bylaws of the  Association,  or (B) based on certificates
of officers of IBSF and the Association and without independent verification, to
the actual  knowledge of such  counsel,  any note,  bond,  mortgage,  indenture,
license,  agreement  or other  instrument  or  obligation  to which  IBSF or the
Association is a party and which was referenced in the IBSF Disclosure Schedule;
or (ii) to the actual  knowledge  of such  counsel,  result in the  creation  or
imposition of any material lien,  instrument or encumbrance upon the property of
IBSF or the  Association,  except such material  lien,  instrument or obligation
that has been disclosed to HUBCO pursuant to the Agreement,  or (iii) violate in
any  material  respect  any order,  writ,  injunction,  or decree  known to such
counsel, or any corporation,  banking or securities statute,  rule or regulation
applicable to IBSF or the Association.

                  (b) IBSF is a corporation  validly  existing under the laws of
the  State  of  New  Jersey,   the   Association  is  a  validly   existing  New
Jersey-chartered savings and loan association under the laws of the State of New
Jersey  and  each of IBSF  and the  Association  has  the  corporate  power  and
authority  to own or lease all of its  properties  and assets and to conduct the
business in which it is currently  engaged as described on pages __ and __ under
the  caption  "_____________________"  in the  Proxy  Statement-Prospectus.  The
deposits of the Association are insured to the maximum extent provided by law by
the Federal Deposit Insurance Corporation.

                  (c) Each IBSF Subsidiary listed as such in the IBSF Disclosure
Schedule  is  validly  existing  under  the  laws  of  the  jurisdiction  of its
incorporation.

                  (d) There is, to the  actual  knowledge  of such  counsel,  no
legal,  administrative,  arbitration or governmental proceeding or investigation
pending or threatened to which IBSF or the  Association  is a party which would,
if  determined  adversely to IBSF or the  Association,  have a material  adverse
effect  on the  business,  properties,  results  of  operations,  or  condition,
financial or  otherwise,  of IBSF or the  Association  taken as a whole or which
presents a claim to restrain or prohibit the  transactions  contemplated  by the
Agreement, except any proceeding or investigation disclosed to HUBCO.

                  (e) No  consent,  approval,  authorization,  or  order  of any
federal or state court or federal or state banking or securities agency or body,
or to such counsel's  actual  knowledge of any third party under any note, bond,
mortgage,  indenture,  license, agreement or other instrument referred to in the
IBSF  Disclosure  Schedule,  is  required  for the  consummation  by IBSF or the
Association of the transactions  contemplated by the Agreement,  except for such
consents,  approvals,  authorizations  or orders as have been  obtained or which
would not have a material  adverse  effect upon HUBCO upon  consummation  of the
Merger.

         In addition to the foregoing opinions,  counsel shall state that on the
sole basis of such  counsel's  participation  in  conferences  with officers and
employees of IBSF in connection  with the  preparation  of the  Prospectus-Proxy
Statement and without other independent  investigation or inquiry,  such counsel
has no reason to believe  that the  Prospectus-Proxy  Statement,  including  any
amendments  or  supplements  thereto  (except  for  the  financial  information,
financial  statements,  notes to financial  statements,  financial schedules and
other financial or statistical data and stock valuation information contained or
incorporated  by reference  therein and except for any  information  supplied by
HUBCO for inclusion therein,  as to which counsel need express no belief), as of
the date of mailing thereof and as of the date of the meeting of shareholders of
IBSF to approve the Merger, contained any untrue statement of a material fact or
omitted to state a material  fact  necessary to make any statement  therein,  in
light of the circumstances under which it was made, not misleading.  Counsel may
state in connection  with the foregoing that such counsel has not  independently
verified and does not assume any responsibility  for the accuracy,  completeness
or fairness of any information or statements  contained in the  Prospectus-Proxy
Statement, except with respect to identified statements of law or regulations or
legal  conclusions  relating  to IBSF  or the  Association  or the  transactions
contemplated  in the  Agreement and that it is relying as to  materiality  as to
factual matters on certificates of officers and  representatives  of the parties
to the Agreement and other factual representations by IBSF and the Association.

                  Such counsel's opinion shall be limited to matters governed by
the  corporate  and  banking  laws of the State of New  Jersey  and the  federal
securities and banking laws and regulations of the United States of America.

                                   EXHIBIT 6.3


                       FORM OF OPINION OF COUNSEL TO HUBCO
                  TO BE DELIVERED TO IBSF ON THE EFFECTIVE TIME



                  (a) HUBCO is a corporation  validly existing under the laws of
the  State  of  New  Jersey,   the  Bank  is  a  validly   existing  New  Jersey
state-chartered  commercial  banking  corporation under the laws of the State of
New Jersey and each of HUBCO and the Bank has the corporate  power and authority
to own or lease all of its properties and assets and to carry on its business as
described in the Proxy Statement-Prospectus on pages __ and __ under the caption
"_____________________________."  HUBCO is registered as a bank holding  company
under the BHCA.

                  (b)  Each  HUBCO  Subsidiary  listed  as  such  in  the  HUBCO
Disclosure  Schedule is validly  existing under the laws of the  jurisdiction of
its incorporation.

                  (c)  The  authorized   capital  stock  of  HUBCO  consists  of
____________  shares of common  stock,  no par  value per share  ("HUBCO  Common
Stock")  and  _____________  shares  of  Series  B,  no par  value,  Convertible
Preferred Stock (the "Authorized Preferred Stock). Except for
 to our  knowledge,  there  are no  outstanding  subscription  rights,  options,
conversion  rights,  warrants or other  agreements or  commitments of any nature
whatsoever  (either firm or conditional)  obligating HUBCO to issue,  deliver or
sell, cause to be issued,  delivered or sold, or restricting  HUBCO from selling
any additional  HUBCO Common Stock or Authorized  Preferred  Stock or obligating
HUBCO to grant, extend or enter into any such agreement or commitment. The HUBCO
Common  Stock to be issued in  connection  with the  Merger in  accordance  with
Article II of the  Agreement,  when so issued in accordance  therewith,  will be
duly  authorized,  validly  issued,  fully  paid  and  non-assessable,  free  of
preemptive rights and free and clear of all liens,  encumbrances or restrictions
created by HUBCO.

                  (d) The Agreement has been authorized,  executed and delivered
by HUBCO and the Bank and  constitutes  a valid and binding  obligation of HUBCO
and the  Bank  enforceable  in  accordance  with  its  terms,  except  that  the
enforceability  of the  obligations  of HUBCO  and the Bank  may be  limited  by
bankruptcy, fraudulent conveyance,  insolvency,  reorganization,  moratorium, or
laws  affecting  institutions  the  deposits of which are insured by the FDIC or
other  laws  heretofore  or  hereafter  enacted  relating  to or  affecting  the
enforcement  of  creditors'   rights  generally  and  by  principles  of  equity
(regardless  of whether such  enforceability  is  considered  in a proceeding in
equity or at law).  In addition,  certain  remedial and other  provisions of the
Agreement may be limited by implied covenants of good faith,  fair dealing,  and
commercially  reasonable  conduct,  by judicial  discretion,  in the instance of
equitable remedies, and by applicable public policies and laws.

                  (e) Subject to satisfaction of the conditions set forth in the
Agreement,  the execution and delivery of the Agreement and the  consummation of
the transactions  contemplated thereby will not (i) conflict with or violate any
provision  of or result in the breach of any  provision  of the  Certificate  of
Incorporation  or Bylaws of HUBCO or the  Charter  and Bylaws of the Bank;  (ii)
based on certificates of officers of HUBCO and without independent verification,
conflict with or violate in any material respect, or result in a material breach
or violation of the terms or provisions  of, or constitute a default  under,  or
result in (whether  upon or after the giving of notice or lapse of time or both)
any material  obligation under, any indenture,  mortgage,  deed of trust or loan
agreement or any other agreement, instrument, judgment, order, arbitration award
or decree of which we have knowledge  (through our  representation  of HUBCO and
the Bank in connection therewith or in the course of our representation of HUBCO
and the Bank in connection with the Agreement) and to which HUBCO or the Bank is
a party or by which HUBCO or the Bank is bound; or (iii) cause HUBCO or the Bank
to violate any corporation or banking law applicable to HUBCO.

                  (f) All actions of the directors and shareholders of HUBCO and
the Bank required by federal  banking laws and regulations and New Jersey law or
by the Certificate of Incorporation or Bylaws of HUBCO and the Bank, to be taken
by HUBCO and the Bank to authorize the  execution,  delivery and  performance of
the Agreement and consummation of the Merger have been taken.

                  (g)  Assuming  that  there has been due  authorization  of the
Merger by all necessary  corporate and  governmental  proceedings on the part of
IBSF and that IBSF has taken all action  required to be taken by it prior to the
Effective  Time,  upon the  appropriate  filing of the  Certificate of Merger in
respect of the Merger with the New Jersey  Secretary of State in accordance with
Section 1.6 of the Agreement,  the Merger will become effective at the Effective
Time,  as such term is defined in Section  1.6,  and upon  effectiveness  of the
Merger each share of IBSF Common  Stock will be converted as provided in Article
II of the Agreement.

                  (h) No approvals, authorizations, consents or other actions or
filings under federal banking law or New Jersey law  ("Approvals")  are required
to be  obtained  by  HUBCO or the Bank in order  to  permit  the  execution  and
delivery of the Agreement by HUBCO or the Bank and the  performance  by HUBCO or
the Bank of the  transactions  contemplated  thereby other than those  Approvals
which have been obtained or those Approvals or consents  required to be obtained
by IBSF.

                  (i) The Registration  Statement has been declared effective by
the Securities and Exchange Commission ("SEC") under the 1933 Act and we are not
aware that any stop order suspending the effectiveness has been issued under the
1933 Act or proceedings therefor initiated or threatened by the SEC.

                  We are not passing  upon and do not assume any  responsibility
for the accuracy,  completeness  or fairness of the statements  contained in the
Proxy Statement-Prospectus and make no representation that we have independently
verified the accuracy,  completeness or fairness of such statement, but from our
examination of the Proxy  Statement-Prospectus  and our general familiarity with
HUBCO no facts have come to our attention that caused us to believe that (except
for financial  statements  and other tabular  financial  information,  and other
financial and statistical  data and  information,  as to which we do not express
any belief) the Proxy  Statement-Prospectus  on the date of the mailing  thereof
and on the date of the meeting of  stockholders  of IBSF at which the  Agreement
was approved,  contained any untrue statement of a material fact regarding HUBCO
or the Merger, or omitted to state a material fact regarding HUBCO or the Merger
therein,  in  light  of the  circumstances  under  which  they  were  made,  not
misleading.

                  We are  members  of the Bar of the State of New  Jersey and we
express no opinion as to any of the laws of any jurisdiction other than the laws
of the State of New Jersey and federal laws and regulations of the United States
of America.

                             STOCK OPTION AGREEMENT

                  THIS STOCK OPTION  AGREEMENT  ("Agreement")  dated as of March
31, 1998, is by and between HUBCO, Inc., a New Jersey corporation and registered
bank  holding  company  ("HUBCO"),   and  IBS  Financial  Corp.,  a  New  Jersey
corporation and registered savings and loan holding company ("IBSF").

                                   BACKGROUND

                  WHEREAS,  HUBCO and IBSF, as of the date hereof,  are prepared
to execute a definitive  agreement  and plan of merger (the "Merger  Agreement")
pursuant to which IBSF will be merged with and into HUBCO (the "Merger"); and

                  WHEREAS,  HUBCO has advised  IBSF that it will not execute the
Merger Agreement unless IBSF executes this Agreement; and

                  WHEREAS,  the Board of Directors of IBSF has  determined  that
the Merger Agreement provides  substantial benefits to the shareholders of IBSF;
and

                  WHEREAS,  as an  inducement  to HUBCO to enter into the Merger
Agreement and in consideration for such entry, IBSF desires to grant to HUBCO an
option to purchase  authorized but unissued shares of common stock of IBSF in an
amount and on the terms and conditions hereinafter set forth.

                                    AGREEMENT

                  In consideration of the foregoing and the mutual covenants and
agreements  set  forth  herein  and in the  Merger  Agreement,  HUBCO  and IBSF,
intending to be legally bound hereby, agree:

                  1. Grant of Option.  IBSF hereby  grants to HUBCO an option to
purchase  2,700,000 shares of common stock, $.01 par value, of IBSF (the "Common
Stock") at a price of $18.00 per share (the  "Option  Price"),  on the terms and
conditions set forth herein (the "Option").

                  2.  Exercise of Option.  This Option shall not be  exercisable
until  the  occurrence  of a  Triggering  Event  (as  such  term is  hereinafter
defined).  Upon or after the  occurrence of a Triggering  Event (as such term is
hereinafter defined), HUBCO may exercise the Option, in whole or in part, at any
time or from time to time,  subject to the terms and conditions set forth herein
and the termination provisions of Section 19 of this Agreement.

                  The term "Triggering Event" means the occurrence of any of the
following events:

                  A person or group (as such terms are defined in the Securities
Exchange  Act of 1934,  as  amended  (the  "Exchange  Act"),  and the  rules and
regulations thereunder) other than HUBCO or an affiliate of HUBCO:

                           a.  acquires  beneficial  ownership  (as such term is
defined in Rule 13d-3 as promulgated  under the Exchange Act) of at least 15% of
the then outstanding shares of Common Stock; or

                           b.  enters  into a letter of intent or an  agreement,
whether  oral or  written,  with  IBSF  pursuant  to which  such  person  or any
affiliate  of such  person  would (i) merge or  consolidate,  or enter  into any
similar transaction, with IBSF, (ii) acquire all or a significant portion of the
assets  or  liabilities  of  IBSF,  or (iii)  acquire  beneficial  ownership  of
securities representing, or the right to acquire beneficial ownership or to vote
securities  representing,  15% or more of the then outstanding  shares of Common
Stock; or

                           c. makes a filing with any bank or thrift  regulatory
authorities  with  respect to or  publicly  announces  a bona fide  proposal  (a
"Proposal") for (i) any merger with, consolidation with or acquisition of all or
a  significant  portion of all the assets or  liabilities  of, IBSF or any other
business  combination  involving  IBSF,  or  (ii) a  transaction  involving  the
transfer of  beneficial  ownership of securities  representing,  or the right to
acquire beneficial ownership or to vote securities representing,  15% or more of
the outstanding  shares of Common Stock, and in either case thereafter,  if such
Proposal has not been Publicly  Withdrawn (as such term is hereinafter  defined)
at least 15 days prior to the meeting of  stockholders of IBSF called to vote on
the  Merger  and  IBSF's  stockholders  fail to  approve  the Merger by the vote
required  by  applicable  law at the  meeting  of  stockholders  called for such
purpose; or

                           d. makes a bona fide  Proposal  and  thereafter,  but
before such  Proposal has been  Publicly  Withdrawn,  IBSF  willfully  takes any
action in any  manner  which  would  materially  interfere  with its  ability to
consummate  the  Merger or  materially  reduce the value of the  transaction  to
HUBCO.

                  The term  "Triggering  Event"  also  means  the  taking of any
material  direct  or  indirect  action by IBSF or any of its  directors,  senior
executive  officers,  investment bankers or other person with actual or apparent
authority  to  speak  for the  Board  of  Directors,  inviting,  encouraging  or
soliciting  any proposal  (other than from HUBCO or an affiliate of HUBCO) which
has as its  purpose a tender  offer for the  shares of Common  Stock,  a merger,
consolidation,  plan of exchange, plan of acquisition or reorganization of IBSF,
or a sale of a significant  number of shares of Common Stock or any  significant
portion of its assets or liabilities.

                  The term  "significant  portion"  means  25% of the  assets or
liabilities of IBSF. The term "significant  number" means 15% of the outstanding
shares of Common Stock.

                  "Publicly  Withdrawn",  for  purposes  of clauses  (c) and (d)
above,  shall mean an unconditional bona fide withdrawal of the Proposal coupled
with a public  announcement of no further  interest in pursuing such Proposal or
in acquiring any  controlling  influence  over IBSF or in soliciting or inducing
any other person (other than HUBCO or any affiliate) to do so.

                  Notwithstanding the foregoing, the Option may not be exercised
at any  time (i) in the  absence  of any  required  governmental  or  regulatory
approval or consent  (including any filing,  approval or consent  required under
the rules and  regulations of the National  Association  of Securities  Dealers,
Inc.)  necessary  for IBSF to issue the  shares of Common  Stock  covered by the
Option (the  "Option  Shares")  or HUBCO to exercise  the Option or prior to the
expiration or termination of any waiting period required by law, or (ii) so long
as any  injunction  or other  order,  decree or ruling  issued by any federal or
state court of competent  jurisdiction  is in effect which prohibits the sale or
delivery of the Option Shares.

                  IBSF shall notify HUBCO  promptly in writing of the occurrence
of any Triggering Event known to it, it being understood that the giving of such
notice by IBSF shall not be a condition  to the right of HUBCO to  exercise  the
Option.  IBSF will not take any action which would have the effect of preventing
or disabling  IBSF from  delivering  the Option Shares to HUBCO upon exercise of
the Option or otherwise performing its obligations under this Agreement,  except
to  the  extent   required  by  applicable   securities  and  banking  laws  and
regulations.

                  In the event HUBCO wishes to exercise the Option,  HUBCO shall
send a written notice to IBSF (the date of which is  hereinafter  referred to as
the "Notice  Date")  specifying  the total number of Option  Shares it wishes to
purchase and a place and date between two and ten business days  inclusive  from
the Notice  Date for the  closing of such a purchase  (a  "Closing");  provided,
however,  that a Closing  shall not occur  prior to two days  after the later of
receipt of any necessary  regulatory approvals and the expiration of any legally
required notice or waiting period, if any.

                  3.  Payment  and  Delivery  of  Certificates.  At any  Closing
hereunder  (a) HUBCO will make  payment to IBSF of the  aggregate  price for the
Option Shares so purchased by wire transfer of immediately available funds to an
account  designated by IBSF; (b) IBSF will deliver to HUBCO a stock  certificate
or certificates  representing the number of Option Shares so purchased, free and
clear of all  liens,  claims,  charges  and  encumbrances  of any kind or nature
whatsoever  created by or through  IBSF,  registered in the name of HUBCO or its
designee,  in such  denominations  as were  specified  by HUBCO in its notice of
exercise and, if necessary,  bearing a legend as set forth below;  and (c) HUBCO
shall pay any transfer or other taxes  required by reason of the issuance of the
Option Shares so purchased.

                  If required under applicable federal securities laws, a legend
will be  placed  on each  stock  certificate  evidencing  Option  Shares  issued
pursuant to this Agreement, which legend will read substantially as follows:

                           The  shares of stock  evidenced  by this  certificate
         have not been registered for sale under the Securities Act of 1933 (the
         "1933  Act").  These shares may not be sold,  transferred  or otherwise
         disposed of unless a registration statement with respect to the sale of
         such  shares has been filed under the 1933 Act and  declared  effective
         or, in the opinion of counsel  reasonably  acceptable  to IBS Financial
         Corp.,  said  transfer  would be  exempt  from  registration  under the
         provisions of the 1933 Act and the regulations promulgated thereunder.

                  No such legend shall be required if a  registration  statement
is filed and declared effective under Section 4 hereof.

                  4.  Registration  Rights.  Upon or after the  occurrence  of a
Triggering  Event and upon receipt of a written request from HUBCO,  IBSF shall,
if necessary for the resale of the Option or the Option Shares by HUBCO, prepare
and file a registration  statement  with the Securities and Exchange  Commission
and any state  securities  bureau  covering the Option and such number of Option
Shares  as HUBCO  shall  specify  in its  request,  and IBSF  shall use its best
efforts to cause such registration  statement to be declared  effective in order
to permit the sale or other  disposition  of the  Option and the Option  Shares,
provided  that HUBCO shall in no event have the right to have more than one such
registration  statement become  effective,  and provided further that IBSF shall
not be  required  to  prepare  and  file  any  such  registration  statement  in
connection with any proposed sale with respect to which counsel to IBSF delivers
to IBSF and to HUBCO (which is  reasonably  acceptable  to HUBCO) its opinion to
the effect that no such filing is required under applicable laws and regulations
with respect to such sale or disposition;  provided further,  however, that IBSF
may delay any  registration of Option Shares above for a period not exceeding 90
days in the  event  that  IBSF  shall  in good  faith  determine  that  any such
registration  would adversely effect an offering of securities by IBSF for cash.
HUBCO shall provide all information  reasonable  requested by IBSF for inclusion
in any registration statement to be filed hereunder.

                  In  connection  with  such  filing,  IBSF  shall  use its best
efforts  to  cause  to  be  delivered  to  HUBCO  such  certificates,  opinions,
accountant's  letters and other documents as HUBCO shall reasonably  request and
as are customarily provided in connection with registrations of securities under
the  Securities  Act of 1933,  as  amended.  All  expenses  incurred  by IBSF in
complying with the provisions of this Section 4, including  without  limitation,
all registration and filing fees,  printing expenses,  fees and disbursements of
counsel  for  IBSF  and  blue  sky  fees  and  expenses  shall  be paid by IBSF.
Underwriting  discounts and  commissions to brokers and dealers  relating to the
Option Shares, fees and disbursements of counsel to HUBCO and any other expenses
incurred by HUBCO in connection with such registration  shall be borne by HUBCO.
In connection  with such filing,  IBSF shall  indemnify and hold harmless  HUBCO
against any losses, claims,  damages or liabilities,  joint or several, to which
HUBCO may become subject, insofar as such losses, claims, damages or liabilities
(or  actions  in  respect  thereof)  arise out of or are based  upon any  untrue
statement or alleged  untrue  statement of any  material  fact  contained in any
preliminary  or final  registration  statement or any  amendment  or  supplement
thereto,  or arise out of a  material  fact  required  to be stated  therein  or
necessary to make the statements therein not misleading; and IBSF will reimburse
HUBCO for any legal or other expense reasonably  incurred by HUBCO in connection
with  investigating  or defending  any such loss,  claim,  damage,  liability or
action;  provided,  however,  that  IBSF  will not be  liable in any case to the
extent that any such loss, claim,  damage or liability arises out of or is based
upon an untrue  statement  or alleged  untrue  statement  or omission or alleged
omission  made in such  preliminary  or  final  registration  statement  or such
amendment or supplement  thereto in reliance upon and in conformity with written
information  furnished  by or on  behalf  of HUBCO  specifically  for use in the
preparation  thereof.  HUBCO will  indemnify  and hold harmless IBSF to the same
extent  as set  forth  in the  immediately  preceding  sentence  but  only  with
reference to written information specifically furnished by or on behalf of HUBCO
for use in the preparation of such preliminary or final  registration  statement
or such amendment or supplement  thereto;  and HUBCO will reimburse IBSF for any
legal  or  other  expense  reasonably   incurred  by  IBSF  in  connection  with
investigating or defending any such loss,  claim,  damage,  liability or action.
Notwithstanding  anything to the contrary herein, no indemnifying party shall be
liable for any settlement effected without its prior written consent.

                  5. Adjustment Upon Changes in Capitalization.  In the event of
any change in the Common Stock by reason of stock dividends, split-ups, mergers,
recapitalizations,  combinations,  conversions, exchanges of shares or the like,
then  the  number  and kind of  Option  Shares  and the  Option  Price  shall be
appropriately adjusted.

                  In the event any capital reorganization or reclassification of
the Common Stock, or any  consolidation,  merger or similar  transaction of IBSF
with another entity,  or any sale of all or  substantially  all of the assets of
IBSF,  shall be effected in such a way that the holders of Common Stock shall be
entitled to receive  stock,  securities or assets with respect to or in exchange
for Common Stock, then, as a condition of such reorganization, reclassification,
consolidation,   merger  or  sale,  lawful  and  adequate  provisions  (in  form
reasonably  satisfactory  to the holder hereof) shall be made whereby the holder
hereof  shall  thereafter  have the right to purchase and receive upon the basis
and upon the terms and  conditions  specified  herein  and in lieu of the Common
Stock  immediately  theretofore  purchasable and receivable upon exercise of the
rights represented by this Option, such shares of stock, securities or assets as
may be issued or payable with respect to or in exchange for the number of shares
of Common Stock immediately theretofore purchasable and receivable upon exercise
of  the   rights   represented   by  this   Option   had  such   reorganization,
reclassification,  consolidation,  merger  or sale not  taken  place;  provided,
however,  that if such  transaction  results  in the  holders  of  Common  Stock
receiving only cash, the holder hereof shall be paid the difference  between the
Option  Price and such  cash  consideration  without  the need to  exercise  the
Option.

                  6. Filings and  Consents.  Each of HUBCO and IBSF will use its
reasonable  efforts to make all filings  with,  and to obtain  consents  of, all
third parties and governmental  authorities necessary to the consummation of the
transactions contemplated by this Agreement.

                  Exercise  of the Option  herein  provided  shall be subject to
compliance with all applicable laws including,  in the event HUBCO is the holder
hereof,  approval  of the  Securities  and  Exchange  Commission,  the  Board of
Governors of the Federal Reserve System, the Office of Thrift  Supervision,  the
Federal Deposit  Insurance  Corporation or the New Jersey Department of Banking,
and IBSF  agrees  to  cooperate  with and  furnish  to the  holder  hereof  such
information  and  documents  as  may  be  reasonably  required  to  secure  such
approvals.

                  7.   Representations  and  Warranties  of  IBSF.  IBSF  hereby
represents and warrants to HUBCO as follows:

                           a. Due  Authorization.  IBSF has full corporate power
and authority to execute,  deliver and perform this  Agreement and all corporate
action  necessary for execution,  delivery and performance of this Agreement has
been duly taken by IBSF.

                           b. Authorized Shares.  IBSF has taken and, as long as
the Option is outstanding, will take all necessary corporate action to authorize
and reserve for issuance all shares of Common Stock that may be issued  pursuant
to any exercise of the Option.

                           c. No  Conflicts.  Neither the execution and delivery
of this  Agreement nor  consummation  of the  transactions  contemplated  hereby
(assuming all  appropriate  regulatory  approvals) will violate or result in any
violation or default of or be in conflict with or constitute a default under any
term of the  Certificate  of  Incorporation  or Bylaws of IBSF or any agreement,
instrument, judgment, decree or order applicable to IBSF.

                  8. Specific  Performance.  The parties hereto acknowledge that
damages  would be an inadequate  remedy for a breach of this  Agreement and that
the  obligations  of the  parties  hereto  shall  be  specifically  enforceable.
Notwithstanding the foregoing,  HUBCO shall have the right to seek money damages
against IBSF for a breach of this Agreement.

                  9. Entire  Agreement.  This Agreement  constitutes  the entire
agreement  between the parties  with  respect to the subject  matter  hereof and
supersedes all other prior agreements and understandings, both written and oral,
among the parties or any of them with respect to the subject matter hereof.

                  10.  Assignment  or  Transfer.  HUBCO may not sell,  assign or
otherwise transfer its rights and obligations hereunder, in whole or in part, to
any  person or group of  persons  other  than to an  affiliate  of HUBCO.  HUBCO
represents  that it is acquiring the Option for HUBCO's own account and not with
a view to or for sale in connection  with any  distribution of the Option or the
Option  Shares.  HUBCO is aware that neither the Option nor the Option Shares is
the subject of a registration  statement filed with, and declared  effective by,
the Securities and Exchange  Commission  pursuant to Section 5 of the Securities
Act, but instead each is being offered in reliance  upon the exemption  from the
registration   requirement   provided   by   Section   4(2)   thereof   and  the
representations and warranties made by HUBCO in connection therewith.

                  11. Amendment of Agreement. Upon mutual consent of the parties
hereto, this Agreement may be amended in writing at any time, for the purpose of
facilitating  performance  hereunder or to comply with any applicable regulation
of any  governmental  authority or any applicable  order of any court or for any
other purpose.

                  12.  Validity.  The  invalidity  or  unenforceability  of  any
provision of this Agreement shall not affect the validity or  enforceability  of
any other  provisions  of this  Agreement,  which shall remain in full force and
effect.

                  13.  Notices.  All  notices,  requests,   consents  and  other
communications  required or permitted hereunder shall be in writing and shall be
deemed to have been duly given when delivered  personally,  by express  service,
cable,  telegram or telex, or by registered or certified mail (postage  prepaid,
return receipt requested) to the respective parties as follows:

                                                                      APPENDIX C

July 10, 1998


The Board of Directors
IBS Financial Corp.
1909 East Route 70
Cherry Hill, New Jersey  08003

Members of the Board:

You have requested our opinion as investment  bankers as to whether the Exchange
Ratio in the Merger (the  "Merger")  between  IBS  Financial  Corp.  ("IBS") and
HUBCO,  Inc.,  Mahwah,  New Jersey  ("HUBCO") as provided  and  described in the
Agreement and Plan of Merger dated March 31, 1998 (the  "Agreement")  is fair to
the holders of IBS Common Stock from a financial point of view.

Pursuant to the Agreement,  IBS shall merge with and into HUBCO,  and each share
of IBS' issued and  outstanding  common stock will be converted  into and become
the right to receive 0.534 shares,  subject to certain  adjustments as set forth
in the  Agreement  (the  "Exchange  Ratio"),  of common stock of HUBCO.  We have
assumed  that  the  Merger  will  qualify  as a tax  free  transaction  for  the
stockholders of IBS and will be accounted for by HUBCO as a pooling-of-interests
transaction.

   

         Ryan,  Beck & Co.,  as a  customary  part  of  its  investment  banking
business,  is engaged in the valuation of banking and savings  institutions  and
their securities in connection with mergers and acquisitions.  In conducting our
investigation and analysis of the Merger, we have met separately with members of
senior  management  of HUBCO and IBS to  discuss  their  respective  operations,
historical financial statements,  strategic plans and future prospects.  We have
reviewed and analyzed material prepared in connection with the Merger, including
but not limited to the following: (i) the Agreement and related documents;  (ii)
the Proxy  Statement / Prospectus;  (iii) HUBCO's Annual Reports to Shareholders
and Annual  Reports on Form 10-K for the years ended  December 31,  1997,  1996,
1995, and 1994, and HUBCO's Quarterly Reports on Form 10-Q for the periods ended
March 31,  1998,  September  30, 1997,  June 30, 1997 and March 31,  1997;  (iv)
HUBCO's  Registration  Statements on Form S-4, dated June 10, 1998, May 8, 1998,
March 17, 1998, February 20, 1998, and November 12, 1997 with respect to HUBCO's
pending  acquisitions  of Dime  Financial  Corp.,  Community  Financial  Holding
Corporation and the then pending acquisitions of MSB Bancorp, Inc., Poughkeepsie
Financial  Corp., and The Bank of Southington,  respectively;  (v) HUBCO's press
releases  dated March 2, 1998 and August 28, 1997 with  respect to HUBCO's  then
pending acquisitions of 22 branches from First Union National Bank, and Security
National  Bank &  Trust  Company  of New  Jersey,  respectively;  (vi)  internal
analyses  prepared  by  HUBCO's   management   containing  pro  forma  financial
statements  and  projections  for  the   acquisitions  of  MSB  Bancorp,   Inc.,
Poughkeepsie  Financial  Corp.,  The Bank of  Southington,  Community  Financial
Holding  Corporation,  22 branches  from First  Union  National  Bank,  Security
National  Bank & Trust  Company  of New  Jersey and Dime  Financial  Corp.  (the
"Acquisitions");  (vii) HUBCO's  Current  Reports on Form 8-K dated July 6, 1998
and July 10, 1998;  (viii) HUBCO's Private  Placement  Memorandum dated June 16,
1998 with respect to the 7.65% Capital  Securities issued by HUBCO Capital Trust
II; (ix) IBS' Annual Reports to Shareholders and Annual Reports on Form 10-K for
the years ended September 30, 1997,  1996, and 1995, and IBS' Quarterly  Reports
on Form 10-Q for the periods ended March 31, 1998,  December 31, 1997,  June 30,
1997, March 31, 1997, and December 31, 1996; (x) the historical stock prices and
trading volume of HUBCO's common stock;  (xi) the publicly  available  financial
data of  commercial  banking  organizations  which Ryan,  Beck deemed  generally
comparable  to HUBCO;  (xii) the  publicly  available  financial  data of thrift
organizations  which Ryan, Beck deemed  generally  comparable to IBS; (xiii) the
historical stock prices and trading volume of IBS' common stock; (xiv) the terms
of recent acquisitions of thrift organizations which Ryan, Beck deemed generally
comparable  in whole or in part to IBS; and (xv) the  potential pro forma impact
of the Merger on HUBCO's  financial  condition,  operating results and per share
figures. We also conducted or reviewed such other studies,  analyses,  inquiries
and examinations as we deemed  appropriate.  Ryan, Beck as part of its review of
the  Merger,  also  analyzed  HUBCO's  ability  to  consummate  the  Merger  and
considered the future prospects of IBS in the event it remained independent.

    

While we have taken care in our investigation and analysis,  we have relied upon
and assumed the accuracy,  completeness  and fairness of the financial and other
information provided to us by the respective  institutions or which was publicly
available and have not assumed any  responsibility  for independently  verifying
such  information.  We have also relied upon the managements of IBS and HUBCO as
to the reasonableness and achievability of the financial and operating forecasts
and projections  (and the assumptions and bases therefor)  provided to us and in
certain  instances  we have  made  certain  adjustments  to such  financial  and
operating   forecasts  which  in  our  judgment  were   appropriate   under  the
circumstances.  In  addition,  we have  assumed  with  your  consent  that  such
forecasts and  projections  reflect the best currently  available  estimates and
judgments of the respective managements. We are not experts in the evaluation of
allowances for loan losses.  Therefore,  we have not assumed any  responsibility
for making an  independent  valuation of the adequacy of the allowances for loan
losses set forth in the balance  sheets of IBS,  HUBCO and the  Acquisitions  at
March 31, 1998,  and we assumed such  allowances  were adequate and comply fully
with applicable law, regulatory policy and sound banking practice as of the date
of such  financial  statements.  We also assumed that the Merger in all respects
is,  and will be  consummated  in  compliance  with  all  laws  and  regulations
applicable  to IBS and  HUBCO.  We have not  made or  obtained  any  independent
evaluations  or  appraisals of the assets and  liabilities  of IBS,  HUBCO,  the
Acquisitions  or  their  respective  subsidiaries,  nor  have  we  reviewed  any
individual  loan  files of IBS,  HUBCO,  the  Acquisitions  or their  respective
subsidiaries.

In conducting our analysis and arriving at our opinion as expressed  herein,  we
have considered  such financial and other factors as we have deemed  appropriate
in the circumstances.  We have assumed, with your consent, that in the course of
obtaining the necessary regulatory approvals for the Merger and the transactions
contemplated  thereby, no restrictions will be imposed that will have a material
adverse effect on the  contemplated  benefits of the Merger or the  transactions
contemplated  thereby. Our opinion is necessarily based on economic,  market and
other  conditions and projections as they exist and can be evaluated on the date
hereof.  Ryan,  Beck did not  express  any  opinion  as to the price or range of
prices at which HUBCO Common Stock might trade subsequent to the Merger.

We have  been  retained  by the  Board  of  Directors  of IBS as an  independent
contractor  to act as  financial  advisor to IBS with  respect to the Merger and
will receive a fee for our  services.  Ryan,  Beck was a co-manager of the 8.98%
Capital  Securities  offering by HUBCO  Capital Trust I. Ryan,  Beck's  research
department  has issued  research  reports on HUBCO and  comments on HUBCO in its
periodic commentaries. Ryan, Beck is also a market maker in HUBCO's common stock
and, in such  capacity,  may from time to time own HUBCO  securities.  As of the
date hereof,  Ryan Beck has no material  investment in HUBCO. Ryan, Beck has had
an investment banking  relationship with IBS Financial  Corporation for a number
of years.  Ryan, Beck was the sole underwriter of IBS' conversion from mutual to
stock form of organization. Additionally, Ryan, Beck has also acted as financial
advisor to IBS with respect to various  other  matters from time to time.  Ryan,
Beck's research  department has issued  research  reports on IBS and comments on
IBS in its  periodic  commentaries.  Ryan,  Beck is also a market  maker in IBS'
common stock and, in such capacity, may from time to time own IBS securities. As
of the date hereof, Ryan Beck has no material investment in IBS.

Our opinion is directed to the Board of Directors of IBS and does not constitute
a  recommendation  to any shareholder of IBS as to how such  shareholder  should
vote at any shareholder meeting held in connection with the Merger.

Based upon and subject to the foregoing it is our opinion as investment  bankers
that the Exchange Ratio in the Merger as provided and described in the Agreement
is fair to the holders of IBS common stock from a financial point of view.

Very truly yours,


RYAN, BECK & CO., INC.

                                     PART II
                     INFORMATION NOT REQUIRED IN PROSPECTUS


Item 20. Indemnification of Directors and Officers.

         (i)  Limitation  of  Liability  of  Directors  and  Officers.   Section
14A:2-7(3) of the New Jersey  Business  Corporation Act permits a corporation to
provide in its Certificate of Incorporation that a director or officer shall not
be personally  liable to the corporation or its  shareholders  for breach of any
duty owed to the  corporation  or its  shareholders,  except that such provision
shall not relieve a director or officer  from  liability  for any breach of duty
based upon an act or omission (a) in breach of such  person's duty of loyalty to
the  corporation  or its  shareholders,  (b) not in good  faith or  involving  a
knowing  violation  of law or (c)  resulting  in receipt  by such  person of any
improper  personal  benefit.   HUBCO's  Certificate  of  Incorporation  includes
limitations  on the  liability of officers and  directors to the fullest  extent
permitted by New Jersey law.

         (ii)  Indemnification  of  Directors,  Officers,  Employees and Agents.
Under Article X of its Certificate of Incorporation,  HUBCO must, to the fullest
extent  permitted by law,  indemnify  its  directors,  officers,  employees  and
agents. Section 14A:3-5 of the New Jersey Business Corporation Act provides that
a  corporation  may  indemnify  its  directors,  officers,  employees and agents
against judgments,  fines,  penalties,  amounts paid in settlement and expenses,
including  attorneys'  fees,  resulting  from various  types of legal actions or
proceedings if the actions of the party being  indemnified meet the standards of
conduct  specified  therein.   Determinations  concerning  whether  or  not  the
applicable  standard of conduct has been met can be made by (a) a  disinterested
majority of the Board of Directors,  (b)  independent  legal counsel,  or (c) an
affirmative  vote  of  a  majority  of  shares  held  by  the  shareholders.  No
indemnification is permitted to be made to or on behalf of a corporate director,
officer,  employee or agent if a judgment or other final adjudication adverse to
such person  establishes  that his acts or  omissions  (A) were in breach of his
duty of loyalty to the  corporation  or its  shareholders,  (B) were not in good
faith or involved a knowing  violation of law or (C) resulted in receipt by such
person of an improper personal benefit.

         (iii)  Insurance.  HUBCO's  directors and officers are insured  against
losses  arising from any claim  against them such as wrongful acts or omissions,
subject to certain limitations.

Item 22.  Undertakings.

1.  The  undersigned   registrant   hereby  undertakes  that,  for  purposes  of
determining  any  liability  under  the  Securities  Act,  each  filing  of  the
registrant's  annual  report  pursuant to Section 13(a) or 15(d) of the Exchange
Act (and,  where  applicable,  each filing of an employee  benefit plan's annual
report  pursuant to Section 15(d) of the Exchange Act) that is  incorporated  by
reference in the registration statement shall be deemed to be a new registration
statement relating to the securities  offered therein,  and the offering of such
securities  at that time shall be deemed to be the  initial  bona fide  offering
thereof.

2. The undersigned  registrant hereby  undertakes as follows:  that prior to any
public  reoffering  of the  securities  registered  hereunder  through  use of a
prospectus  which is a part of this  registration  statement,  by any  person or
party who is deemed to be an underwriter  within the meaning of Rule 145(c), the
issuer  undertakes that such reoffering  prospectus will contain the information
called for by the  applicable  registration  form with respect to reofferings by
persons who may be deemed  underwriters,  in addition to the information  called
for by the other Items of the applicable form.

3. The registrant undertakes that every prospectus (i) that is filed pursuant to
paragraph  2  immediately   preceding,   or  (ii)  that  purports  to  meet  the
requirements  of  Section  10(a)  (3) of the  Securities  Act  and  is  used  in
connection with an offering of securities  subject to Rule 415, will be filed as
a part of an amendment to the registration  statement and will not be used until
such amendment is effective, and that, for purposes of determining any liability
under the Securities Act, each such post-effective  amendment shall be deemed to
be a new registration  statement relating to the securities offered therein, and
the offering of such  securities  at that time shall be deemed to be the initial
bona fide offering thereof.

4. Insofar as indemnification  for liabilities  arising under the Securities Act
may  be  permitted  to  directors,  officers  and  controlling  persons  of  the
registrant pursuant to the foregoing  provisions,  or otherwise,  the registrant
has been advised that in the opinion of the Securities  and Exchange  Commission
such  indemnification  is against  public policy as expressed in the Act and is,
therefore,  unenforceable. In the event that a claim for indemnification against
such liabilities  (other than the payment by the registrant of expenses incurred
or paid by a director,  officer or  controlling  person of the registrant in the
successful  defense of any  action,  suit or  proceeding)  is  asserted  by such
director,  officer or controlling person in connection with the securities being
registered, the registrant will, unless in the opinion of its counsel the matter
has been  settled by  controlling  precedent,  submit to a court of  appropriate
jurisdiction the question whether such  indemnification  by it is against public
policy as  expressed  in the  Securities  Act and will be  governed by the final
adjudication of such issue.

5. The  undersigned  registrant  hereby  undertakes  to respond to requests  for
information  that is incorporated  by reference into the prospectus  pursuant to
Items 4, 10(b),  11, or 13 of this Form,  within one  business day of receipt of
such  request,  and to send the  incorporated  documents  by first class mail or
other equally  prompt means.  This includes  information  contained in documents
filed subsequent to the effective date of the registration statement through the
date of responding to the request.

6. Subject to appropriate  interpretation,  the  undersigned  registrant  hereby
undertakes  to supply by means of a  post-effective  amendment  all  information
concerning a transaction,  and the company being acquired involved therein, that
was not the subject of and included in the registration statement when it became
effective.

7. The  undersigned  registrant  hereby  undertakes  to  deliver  or cause to be
delivered with the prospectus,  to each person to whom the prospectus is sent or
given,  the latest annual  report to security  holders that is  incorporated  by
reference  in  the  prospectus  and  furnished   pursuant  to  and  meeting  the
requirements  of Rule 14a-3 and Rule 14c-3 under the Securities  Exchange Act of
1934;  and,  where  interim  financial  information  required to be presented by
Article 3 of Regulation S-X is not set forth in the prospectus,  to deliver,  or
cause to be  delivered to each person to whom the  prospectus  is sent or given,
the latest  quarterly  report that is specifically  incorporated by reference in
the prospectus to provide such interim financial information.

8. The undersigned  registrant  hereby  undertakes to file, during any period in
which  offers  or sales are  being  made,  a  post-effective  amendment  to this
registration statement:

         (i) To include  any  prospectus  required  by Section  10(a)(3)  of the
Securities Act of 1933;

         (ii) To reflect in the prospectus any facts or events arising after the
effective date of the registration  statement (or the most recent post-effective
amendment  thereof)  which,  individually  or  in  the  aggregate,  represent  a
fundamental  change in the information set forth in the registration  statement.
Notwithstanding the foregoing,  any increase or decrease in volume of securities
offered (if the total dollar value of  securities  offered would not exceed that
which  was  registered)  and any  deviation  from  the  low or  high  end of the
estimated  maximum  offering  range may be reflected  in the form of  prospectus
filed with the  Commission  pursuant  to Rule 424(b) if, in the  aggregate,  the
changes in volume  and price  represent  no more than 20  percent  change in the
maximum  aggregate  offering price set forth in the "Calculation of Registration
Fee" table in the effective registration statement.

         (iii) To include any material  information  with respect to the plan of
distribution  not  previously  disclosed  in the  registration  statement or any
material change to such information in the registration statement.

9. The  undersigned  registrant  hereby  undertakes  that,  for the  purpose  of
determining   any  liability  under  the  Securities  Act  of  1933,  each  such
post-effective  amendment  shall be  deemed to be a new  registration  statement
relating to the securities offered therein,  and the offering of such securities
at the time shall be deemed to be the initial bona fide offering thereof.

10. The undersigned  registrant hereby undertakes to remove from registration by
means of a post-effective amendment any of the securities being registered which
remain unsold at the termination of the offering.
