Item 5.  Other Events

         On March 31, 1998, 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. ("IBSF"), a New Jersey corporation and registered
savings and loan holding company, and Inter-Boro Savings and Loan Association
(the "Association"), a New Jersey state-chartered savings and loan association
wholly owned by IBSF, entered into an Agreement and Plan of Merger (the
"Agreement") which sets forth the terms and conditions under which IBSF will
merge with and into HUBCO (the "Merger").

         The Agreement provides that upon consummation of the Merger, and
subject to certain further terms, conditions, limitations and procedures set
forth in the Agreement, each issued and outstanding share of common stock, par
value $.01, of IBSF ("IBSF Common Stock") shall, by virtue of the Merger, be
converted into and represent the right to receive 0.534 shares of common stock,
no par value, of HUBCO ("HUBCO Common Stock"). Based upon HUBCO's March 30, 1998
closing price of $38.81 per share of HUBCO Common Stock, 0.534 shares of HUBCO
Common Stock would have a value of $20.73. This $20.73 value equates to an
aggregate of $227 million for the currently issued and outstanding IBSF Common
Stock, or 176% of IBSF's book value at December 31, 1997, and 38 times IBSF's
reported earnings for the last 12 months. The Merger Agreement contains
customary anti-dilution measures. The 0.534 exchange ratio also is subject to
potential upward adjustment at the election of HUBCO if IBSF elects to terminate
the Agreement in the event the Median Pre-Closing Price (as defined in Section
2.2(e) of the Agreement) of the HUBCO Common Stock declines by more than 15% and
by more than 10% compared to a peer group. The Agreement further provides for
the merger of the Association with and into the Bank.

         Concurrently with the execution and delivery of the Agreement, IBSF
entered into a Stock Option Agreement with HUBCO (the "Stock Option Agreement")
whereby IBSF granted to HUBCO an option to purchase 2,700,000 shares of
authorized and unissued IBSF Common Stock, at a price of $18.00 per share, which
is exercisable only upon the occurrence of certain events. The Stock Option
Agreement provides the grantee with the right to require the issuer to register
the Common Stock acquired by or issuable upon exercise of the option under the
Securities Act of 1933, as amended.

         The transaction, which is expected to close in the third quarter of
1998, is expected to be treated as a tax free exchange to holders of IBSF Common
Stock and be accounted for as a pooling of interests. Consummation of the Merger
is subject to the approval of the Merger by the shareholders of IBSF and the
receipt of all required regulatory approvals, as well as other customary
conditions.

         The Agreement, the Stock Option Agreement and the press release issued
by IBSF on March 31, 1998 regarding the Merger are attached as exhibits to this
report and are

the Stock Option Agreement do not purport to be complete and are qualified in

<PAGE>

                          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 

<PAGE>


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 


                                       2
<PAGE>


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).


                                       3
<PAGE>


                           (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, 


                                       4
<PAGE>


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 


                                       5
<PAGE>


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 


                                       6
<PAGE>


"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 


                                       7
<PAGE>


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,
purchase, subscription or issuance of any shares of capital stock of IBSF or the
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.

                  3.3.  Authority; No Violation.

                  (a) Subject to the approval of this Agreement and the
transactions contemplated hereby by all applicable regulatory authorities and by
the shareholders of IBSF, and except as set forth in the IBSF Disclosure
Schedule, IBSF and the Association have the full corporate power and authority
to execute and deliver this Agreement and to consummate the transactions

delivery of this Agreement and the consummation of the transactions contemplated
hereby have been duly and validly approved by the directors of IBSF and the
Association in accordance with their respective Certificate of Incorporation and
Bylaws and applicable laws and regulations. Except for such approvals, no other
corporate proceedings not otherwise contemplated hereby on the part of IBSF or
the Association are necessary to consummate the transactions so contemplated.
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
applicable to IBSF, the Association or any of their respective properties or
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 


                                       9
<PAGE>


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 


                                       10
<PAGE>


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.


                                       11
<PAGE>



                  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.


                                       12
<PAGE>



                  (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.


                                       13
<PAGE>


                  (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 


                                       14
<PAGE>

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

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

<PAGE>

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 


                                       18
<PAGE>

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.

                  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 

                                       20

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)

constitute a default) under, result in the termination of, accelerate the

<PAGE>

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 


                                       22
<PAGE>

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 


                                       23
<PAGE>

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 


                                       25
<PAGE>

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, 


                                       26
<PAGE>

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 


                                       27
<PAGE>

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.

businesses only in the ordinary course and consistent with prudent business
practice, except for transactions permitted hereunder or with the prior written
consent of HUBCO, which consent will not be unreasonably withheld. Each of IBSF
and the Association also shall use its reasonable best efforts to (i) preserve
its business organization and that of the IBSF Subsidiaries intact, (ii) keep
available to itself and the IBSF Subsidiaries the present services of their
respective employees, and (iii) preserve for itself and HUBCO the goodwill of
its customers and those of the IBSF Subsidiaries and others with whom business
relationships exist.

         thereof) or issue or grant any option, warrant, call, commitment,
         subscription, right to purchase or agreement of any character relating
         to its authorized or issued capital stock, or any securities
         convertible into shares of such stock, or split, combine or reclassify

         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
         pursuant to policies or contracts of IBSF in effect on the date hereof

         into or amend any employment or severance agreement with, any of its
         directors, officers or employees; adopt any new employee benefit plan
         or arrangement of any type; or award any increase in compensation or

         or in response to substantial financial demands upon the business of
         IBSF or the Association;

                  (f) make any capital expenditures in excess of $50,000 in the
         aggregate, other than pursuant to binding commitments existing on 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;

         practices, other than changes required in accordance with generally
         accepted accounting principles or regulatory authorities;

                  (j) take any action that would result in any of its
         representations and warranties contained in Article III of this
         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

         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



                                       30
<PAGE>

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

                  5.6.  Regulatory Matters.

                  (a) For the purposes of holding the Shareholders Meeting (as

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

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.

                                       35
<PAGE>

                  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.

                                       36
<PAGE>

                  (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


                                       37
<PAGE>

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 

                                       38
<PAGE>

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

                                       39
<PAGE>

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 


                                       40
<PAGE>

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


                                       41
<PAGE>

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 


                                       42
<PAGE>

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:

                                       43
<PAGE>

                  (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 


                                       44
<PAGE>

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 


                                       45
<PAGE>

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;

                                       47
<PAGE>

                  (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 


                                       48
<PAGE>

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

                           between HUBCO (as grantee)

<PAGE>

                             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:


<PAGE>




                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.



                                       2
<PAGE>

                  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.

                                       3
<PAGE>

                  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 


                                       4
<PAGE>

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.

                                       5
<PAGE>

                      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:

        IBS FINANCIAL CORP. ANNOUNCES PROPOSED MERGER WITH HUBCO, INC.
        --------------------------------------------------------------
                   WITH A TRANSACTION VALUE OF $227 MILLION
                   ----------------------------------------


    Cherry Hill, New Jersey, March 31, 1998 -- IBS Financial Corp. 
(NASDAQ;IBSF), the holding company for Inter-Boro Savings and Loan 
Association, announced today that it has agreed to merge with HUBCO, Inc. of 
Mahwah, New Jersey, on a stock for stock exchange basis. The Agreement and 
Plan of Merger provides that each share of IBSF common stock shall be 
exchanged for 0.534 shares of HUBCO common stock, subject to adjustment under 
limited circumstances noted below. Based on HUBCO's March 30, 1998 closing 
price of $38.81 for its common stock, 0.534 shares equates to a per share 
price of $20.73 and an aggregate price of $227 million for the issued and 
outstanding shares. Based on IBSF's December 31, 1997 shareholders' equity 
and its last twelve months reported earnings, the transaction value is 
approximately 1.76 times book value and 38 times reported earnings.

    Joseph M. Ochman, Sr., Chairman, President and Chief Executive Officer of 
IBS stated "The Board of Directors of IBS is very pleased and gratified at 
the opportunity to affiliate with HUBCO, Inc., a dynamic and growing New 
Jersey-based bank holding company. We believe this transaction is in the best 
interests of our shareholders, our customers and the communities of South 
Jersey that we serve." Mr. Ochman went on to state that "(t)he merger will 
permit the customers of Inter-Boro Savings to access many new products and 
services which are currently offered by HUBCO and Hudson United Bank, its New 
Jersey-based subsidiary bank."

   Kenneth T. Nielson, HUBCO's Chairman, President and Chief Executive 
Officer commented, "We are very pleased to have IBSF choose to join the HUBCO 
organization. This institution significantly strengthens our market share and 
penetration in South Jersey, a market that we consider very attractive."

   In accordance with the definitive agreement, the merger is conditioned 
upon, among other things, receipt of necessary regulatory approvals, receipt 
of approval by IBSF shareholders, the transaction qualifying as a tax free 
merger and the ability to account for the merger as a pooling of interests. 
In addition, IBSF has certain rights to terminate the agreement if HUBCO's 
share price should decrease more than 15% from the day after the announcement 
and a pre-closing determination date and also decrease more than 10% of a 
specified index, unless HUBCO agrees to increase the exchange ratio in such 
circumstances. The parties anticipate that the merger will be consummated in 
the third quarter of 1998. In connection with the merger, IBSF has issued an 
option to HUBCO that, under certain defined circumstances, would enable HUBCO 
to purchase up to 2,700,000 shares of IBSF common stock.

   Concurrent with the announcement of this transaction, HUBCO announced that 
it had entered into a definitive agreement to acquire Dime Financial 
Corporations (NASDAQ:DIBK), the holding company for Dime Savings Bank of 
Willingford, Connecticut, a $961 Million asset institution that operates 
eleven offices in New Haven County, Connecticut. Under the terms of the Dime 
agreement, Dime common shareholders will receive HUBCO common stock with an 
indicated value of $38.25 per share which equates to a total transaction 
value of approximately $201 million.

   HUBCO, Inc. is the holding company of Hudson United Bank in New Jersey and 
Lafayette American Bank in Connecticut. During the second quarter of 1998, 
HUBCO expects to add a New York subsidiary under the name "Bank of the 
Hudson" through its pending acquisitions of Poughkeepsie Financial Corp. and 
MSB Bancorp, Inc. and their subsidiary banks.

   IBS Financial Corp. is a unitary savings and loan holding company 
conducting business through its wholly-owned subsidiary, Inter-Boro Savings 
and Loan Association. The Association is a New Jersey chartered, SAIF-insured 
savings institution operating through nine full-service offices located in 
Camden, Burlington, and Gloucester Counties, New Jersey. The Company's 
headquarters is located at 1909 East Route 70, Cherry Hill, New Jersey 08003.

   The Company's common stock is traded on the Nasdaq National Market under 
the symbol "IBSF."
