(1) Estimated solely for the purpose of calculating the registration fee has
    been computed pursuant to Rule 457(f)(1) under the Securities Act of 1933,
    as amended, based on the average of the high and low prices for shares of
    Common Stock of Pulse Bancorp, Inc. ("Pulse") reported on the Nasdaq Stock
    Market on September 10, 1998, and the maximum number of such shares
    (3,406,288) that may be exchanged for the securities being registered. The
    proposed maximum offering price per share has been determined by dividing
    the portion of the proposed maximum aggregate offering price by the number
    of shares being registered.
 
  The Registrants hereby amend this Registration Statement on such date or
dates as may be necessary to delay its effective date until the Registrants
shall file a further amendment which specifically states that this
Registration Statement shall thereafter become effective in accordance with
Section 8(a) of the Securities Act of 1933 or until the Registration Statement
shall become effective on such date as the Commission, acting pursuant to
Section 8(a), may determine.

                          FIRST SOURCE BANCORP, INC.
    
Dear First Source Stockholder:
   
  You are cordially invited to attend a Special Meeting of Stockholders of
First Source Bancorp, Inc. ("First Source") which will be held on Wednesday,
December 16, 1998 at 10:30 a.m., local time, at the Sheraton at Woodbridge
Place, 515 Route 1 South, Iselin, New Jersey (the "Special Meeting"). At this
meeting, you will be asked to consider and vote upon: (i) a proposal to
approve an Agreement and Plan of Merger, dated July 9, 1998 (the "Merger
Agreement"), pursuant to which Pulse Bancorp, Inc. ("Pulse") will be merged
with and into First Source and the stockholders of Pulse will become
stockholders of First Source; (ii) a proposal to approve and adopt the First
Source Bancorp, Inc. 1998 Stock-Based Incentive Plan (the "Incentive Plan");
and (iii) a proposal to approve and adopt an amendment to the First Source
Certificate of Incorporation to change the name of the company to First
Sentinel Bancorp, Inc. (the "Corporate Name Amendment").     
   
  Your shares of First Source Common Stock will be unaffected by the merger.
Upon consummation of the merger, Pulse's former stockholders will own
approximately 26.8% of First Source's outstanding common stock, assuming the
merger was completed as of October 30, 1998 at an Exchange Ratio of 3.710.
       
  The proposed merger has been unanimously approved by the Board of Directors
of each company. Your Board of Directors believes that the merger will provide
significant value to First Source's stockholders by extending the markets
served by First Source and allowing First Source to provide a broader array of
services to Pulse's customers. Your Board has determined that the merger is in
the best interests of First Source and its stockholders and unanimously
recommends that you vote FOR approval of the Merger Agreement. The investment
banking firm of Ryan, Beck & Co., Inc. ("Ryan, Beck") has issued a written
opinion to your Board of Directors that, as of the date of such opinion, the
Exchange Ratio (as defined herein) in the merger was fair to First Source and
its stockholders from a financial point of view. The written opinion of Ryan,
Beck is reproduced in full as Annex D to the accompanying Joint Proxy
Statement/Prospectus, and First Source's stockholders are urged to read
carefully such opinion in its entirety.     
 
  Consummation of the merger is subject to certain conditions, including the
approval of the Merger Agreement by the holders of a majority of the shares of
each of First Source's and Pulse's common stock and the approval of the merger
by various regulatory agencies.
 
  The Incentive Plan has been unanimously approved by the Board of Directors
of First Source. The Board of Directors has determined that the Incentive Plan
is in the best interest of First Source as it will help attract and retain
qualified personnel in key positions, provide such personnel with a
proprietary interest in First Source as an incentive to contribute to the
success of First Source, continue to promote the attention of management to
other stockholders' concerns and reward employees for outstanding performance.
A copy of the Incentive Plan is attached as Annex E.
   
  The Corporate Name Amendment has been unanimously approved by the Board of
Directors of First Source. The Board of Directors believes it is in the best
interest of the company to change its name to First Sentinel Bancorp, Inc. A
copy of the Corporate Name Amendment is attached as Annex F.     
 
  Specific information regarding the Special Meeting is contained in the
enclosed Notice of Special Meeting and Joint Proxy Statement/Prospectus.
Please read these materials carefully.
   
  It is very important that your shares are represented at the Special
Meeting, whether or not you plan to attend in person. A failure to vote FOR
approval of the Merger Agreement or any of the other matters presented will
have the same effect as a vote against the Merger Agreement or such other
matter. Therefore, I urge you to     
<PAGE>
 
execute, date and return the enclosed proxy card in the enclosed postage-paid
envelope as soon as possible to assure that your shares will be voted at the
Special Meeting.
 
  On behalf of the Board of Directors, I thank you for your support and urge
you to vote FOR approval of the Merger Agreement, the Incentive Plan and the
Corporate Name Amendment.
 
                                          Sincerely,
                                          /s/ John P. Mulkerin
                                          John P. Mulkerin
                                          President and Chief Executive
                                           Officer
 
                     THE BOARD OF DIRECTORS RECOMMENDS THAT
                           YOU VOTE FOR THE PROPOSALS
                   TO APPROVE AND ADOPT THE MERGER AGREEMENT,
                  TO APPROVE AND ADOPT THE INCENTIVE PLAN AND
               TO APPROVE AND ADOPT THE CORPORATE NAME AMENDMENT.
               PLEASE COMPLETE, DATE AND SIGN THE ENCLOSED PROXY
       AND MAIL IT PROMPTLY IN THE ENCLOSED POSTAGE-PAID RETURN ENVELOPE.

Dear Fellow Stockholder:
   
  On behalf of the Board of Directors and management of Pulse Bancorp, Inc.
("Pulse"), I cordially invite you to attend a special meeting of stockholders
to be held at the Holiday Inn, Forsgate Drive, Jamesburg, New Jersey, on
Wednesday, December 16, 1998, at 9:00 a.m. The attached Notice of the Meeting
of the Stockholders and Joint Proxy Statement/Prospectus describe the formal
business to be transacted at the meeting.     
   
  At this important meeting, stockholders will be asked to approve a merger
agreement between First Source Bancorp, Inc. ("First Source") and Pulse,
pursuant to which Pulse will merge with and into First Source, with First
Source as the surviving corporation, and First Source will issue shares of its
common stock to stockholders of Pulse. The terms of the merger, including the
method for determining the amount of First Source common stock to be issued as
well as other important information relating to First Source and the combined
company, are contained in the accompanying Joint Proxy Statement/Prospectus.
Please give this document your careful attention.     
   
  The Board of Directors of Pulse has carefully reviewed and considered the
terms and conditions of the merger agreement. THE BOARD OF DIRECTORS OF PULSE
HAS CONCLUDED THAT THE MERGER AGREEMENT AND THE PROPOSED MERGER ARE IN THE BEST
INTEREST OF THE STOCKHOLDERS OF PULSE, AND UNANIMOUSLY RECOMMENDS THAT PULSE
STOCKHOLDERS VOTE "FOR" THE MERGER AGREEMENT. THE INVESTMENT BANKING FIRM OF
SANDLER O'NEILL & PARTNERS, L.P. HAS ISSUED A WRITTEN OPINION THAT THE EXCHANGE
RATIO (AS DEFINED HEREIN) IS FAIR FROM A FINANCIAL POINT OF VIEW TO PULSE
STOCKHOLDERS, AND THE OPINION IS ATTACHED AS ANNEX C OF THIS JOINT PROXY
STATEMENT/PROSPECTUS.     
 
  I encourage you to attend the meeting in person. Whether or not you do,
please read the Joint Proxy Statement/Prospectus and then complete, sign and
date the proxy card and return it in the enclosed postage-paid envelope. This
will save Pulse additional expense in soliciting proxies and will ensure that
your shares are represented. You may vote in person at the meeting even if you
have previously returned the proxy. However, if you are a stockholder whose
shares are not registered in your own name, you will need additional
documentation from your record holder to vote in person at the meeting.
 
  Thank you for your prompt attention to this important matter.
 
                                         Sincerely,
                                         /s/ George T. Hornyak, Jr.
                                         George T. Hornyak, Jr.

  First Source. First Source is a Delaware Corporation, incorporated in 1997,
which acquired all of the stock of First Savings Bank, SLA ("First Savings")
upon First Savings' conversion and reorganization from a mutual holding company
ownership format to a stock holding company format. The conversion and
reorganization was completed in April 1998 (the "1998 Conversion and
Reorganization").
   
  First Savings is a New Jersey-chartered capital stock savings and loan
association headquartered in Woodbridge, New Jersey. First Savings has operated
in its present market area since 1901. Until 1992, First Savings operated in
the mutual form of organization. In July 1992, First Savings reorganized to
become a federally-chartered mutual holding company, First Savings Bancshares,
MHC (the "Mutual Holding Company"), and simultaneously formed a newly-chartered
New Jersey stock savings association, First Savings Bank, SLA, as a majority-
owned subsidiary of the Mutual Holding Company (the "1992 MHC Reorganization").
The Mutual Holding Company transferred substantially all of its assets (except
$1.0 million in cash) and all its liabilities to the newly organized
association in exchange for 1,660,000 shares of First Savings Common Stock.
Concurrently with the 1992 MHC Reorganization, First Savings sold one million
shares of its common stock to the general public at $10 per share, resulting in
net proceeds of $9.2 million. Upon completion     
 
                                       3
<PAGE>
 
   
of the 1992 MHC Reorganization, 62.4% of the First Savings Common Stock
outstanding was held by the Mutual Holding Company. Subsequently, First Savings
completed a Secondary Stock Offering of 600,000 shares of common stock at
$13.00 per share on July 11, 1995, which resulted in a decrease in the Mutual
Holding Company's ownership interest from 62.4% to 52.5%. By October 31, 1997,
the Mutual Holding Company's ownership interest had decreased to 51.6% due to
the exercise of stock options. In connection with the 1998 Conversion and
Reorganization, First Savings became the wholly-owned subsidiary of First
Source, and the Mutual Holding Company was dissolved.     
   
  First Savings' deposits are insured by the FDIC under the SAIF. First Savings
has been a member of the Federal Home Loan Bank System ("FHLB") since 1945.
    
  First Savings is a community-oriented institution that offers traditional
deposit and loan products. It operates 17 full service offices in its market
area of Middlesex, Monmouth and Union Counties in New Jersey. First Savings'
principal business has been, and continues to be, attracting retail deposits
from the general public and investing those deposits, together with funds
generated from operations and borrowings, primarily in single-family
residential mortgage loans, real estate construction loans, commercial real
estate loans and home equity loans and lines of credit. First Savings also
invests in U.S. Government and federal agency securities and other marketable
securities. First Savings' revenues are derived principally from interest on
its mortgage loan and mortgage-backed securities portfolios, and interest and
dividends on its investment securities.
 
  At June 30, 1998, First Source had assets of $1.2 billion, deposits of $807.6
million and stockholders' equity of $259.3 million. The principal executive
offices of First Source are located at 1000 Woodbridge Center Drive,

and in the best interests of, Pulse and its stockholders. The Pulse Board

has unanimously approved the Merger Agreement and has determined that the
Merger is fair to, and in the best interests of, First Source and its
stockholders. The First Source Board recommends unanimously that First Source's
stockholders vote FOR approval of the Merger Agreement. See "THE MEETINGS--
First Source Meeting--Recommendation of the Board of Directors" and "THE
MERGER--Background of the Merger" and "--Recommendation of the Boards of
Directors; Reasons for the Merger".
 
EFFECT OF THE MERGER AND THE SUBSIDIARY BANK MERGER
 
  Pursuant to the Merger Agreement, at the Effective Time (as defined below),
Pulse will be merged with and into First Source, and Pulse stockholders will
become stockholders of First Source. See "THE MERGER--General."
   
  Immediately following the consummation of the Merger, Pulse Bank will merge
with and into First Savings (the "Subsidiary Bank Merger"). First Savings will
continue as a New Jersey chartered savings and loan association and a wholly-
owned subsidiary of First Source for the forseeable future. See "THE MERGER--
General" and "CERTAIN RELATED TRANSACTIONS--Subsidiary Bank Merger Agreement."
    
EFFECTIVE TIME
 
  The Merger will become effective upon the filing of a certificate of merger
with the Secretary of State of the State of Delaware in accordance with
applicable law or on such later date as the certificate may specify (the
"Effective Time"). The certificate will be filed on the first day which is (i)
the last business day of a month and
 
                                       5
<PAGE>
 
(ii) at least two business days after satisfaction or waiver of the latest to
occur of certain conditions to the Merger specified in the Merger Agreement,
unless another date is agreed to by First Source and Pulse. See "THE MERGER--
Effective Time."
 
EXCHANGE RATIO
   
  At the Effective Time, each issued and outstanding share of Pulse Common
Stock, except for shares held directly or indirectly by First Source or Pulse
(other than shares held by First Source or Pulse in a fiduciary capacity
("Trust Account Shares") or in respect of a debt previously contracted ("DPC
Shares")), will be converted into and exchangeable for a certain number of
shares of First Source Common Stock as determined by the Exchange Ratio.
Subject to certain qualifications, the Exchange Ratio will be as follows: (i)
subject to certain provisions of the Merger Agreement, if the Average Closing
Price of First Source Common Stock is equal to or greater than $11.50, the
Exchange Ratio shall be equal to 3.2; (ii) if the Average Closing Price is
$10.00 or greater but less than $11.50, the Exchange Ratio shall be 3.2; (iii)
if the Average Closing Price is greater than $8.50 but less than $10.00, the
Exchange Ratio shall equal $32.00 divided by the Average Closing Price; or
(iv) subject to certain provisions of the Merger Agreement, if the Average
Closing Price is equal to or less than $8.50, the Exchange Ratio shall be
3.764.     
 
  The formula for determining the Exchange Ratio was arrived at through arms-
length negotiations between Pulse and First Source.
   
  If the Valuation Date had been October 30, 1998, the Exchange Ratio would
have been 3.710. For further information concerning the market prices of First
Source Common Stock and Pulse Common Stock, see "MARKET PRICES AND DIVIDEND
INFORMATION."     
   
  Pulse has the right to terminate the Agreement if the Average Closing Price
of First Source is less than $8.50 per share, unless First Source provides
notice pursuant to the Agreement that it wants to proceed with the Merger, in
which event First Source will pay consideration in the form of First Source
Common Stock equal to $32.00 per share for Pulse common stock. Assuming the
Merger is approved by Pulse stockholders, the Pulse Board may elect not to
terminate the Merger Agreement and to consummate the Merger without
resoliciting Pulse stockholders if the Average Closing Price is less than $8.50
and First Source chooses not to increase the consideration, even though, as a
result of the application of the Exchange Ratio, the value of the shares of
First Source Common Stock (valued at the Average Closing Price) issued in
exchange for each share of Pulse Common Stock would be less than $32.00. In
such a situation, in considering whether to consummate the Merger without the
resolicitation of Pulse stockholders, the Pulse Board will take into account,
consistent with its fiduciary duties, all relevant facts and circumstances that
exist at such time including, without limitation, its evaluation of the then-
existing economic conditions and trends, its evaluation of the respective
business, financial condition, results of operations and prospects of each of
Pulse and First Source, its evaluation of the overall condition of the thrift
and commercial banking industry and the advice of its financial advisor and
legal counsel.     
 
  Assuming the Merger is approved by the holders of First Source Common Stock
and the Average Closing Price is less than $8.50, the First Source Board may
elect to increase the Exchange Ratio and to consummate the Merger without
resoliciting First Source stockholders even though, a result of such
adjustment, the number of shares of First Source Common Stock to be issued in
the Merger would increase. In such a situation, in considering whether to
increase the Exchange Ratio and consummate the Merger without the
resolicitation of First Source stockholders, the First Source Board will take
into account, consistent with its fiduciary duties, all relevant facts and
circumstances that exist at such time, including, without limitation, the
advice of its financial advisor and legal counsel. Such relevant facts and
circumstances would include the First Source Board's evaluation of the dilutive
impact of a higher Exchange Ratio to First Source's stockholders, its
evaluation of the strategic importance to First Source of the acquisition of
Pulse relative to any such dilutive impact and the accretive prospects of the
acquisition, its evaluation of the synergies of Pulse's business relative to
First Source,
 
                                       6
<PAGE>
 
Pulse's financial condition, operating performance and prospects, and the
advice of First Source's financial advisor as to the fairness of such higher
Exchange Ratio to First Source stockholders from a financial point of view.
   
  First Source has the right to terminate the Agreement if the Average Closing
Price of First Source is greater than $11.50 per share, unless Pulse provides
notice pursuant to the Agreement that it wants to proceed with the Merger, in
which event First Source will pay consideration in the form of First Source
Common Stock equal to $36.80 per share for Pulse Common Stock. Assuming the
Merger is approved by First Source stockholders, the First Source Board may
elect not to terminate the Merger Agreement and to consummate the Merger
without resoliciting First Source stockholders if the Average Closing Price is
greater than $11.50 and Pulse chooses not to decrease the consideration, even
though, as a result of the application of the Exchange Ratio, the value of the
shares of First Source Common Stock (valued at the Average Closing Price)
issued in exchange for each share of Pulse Common Stock would be greater that
$36.80. In such a situation, in considering whether to consummate the Merger
without the resolicitation of First Source stockholders, the First Source Board
will take into account, consistent with its fiduciary duties, all relevant
facts and circumstances that exist at such time including, without limitation,
its evaluation of the then-existing economic conditions and trends, its
evaluation of the respective business, financial condition, results of
operations and prospects of each of Pulse and First Source, its evaluation of
the overall condition of the thrift and commercial banking industry and the
advice of its financial advisor and legal counsel.     
 
  Assuming the Merger is approved by the holders of Pulse Common Stock and the
Average Closing Price is greater than $11.50, the Pulse Board may elect to
decrease the Exchange Ratio and to consummate the Merger without resoliciting
Pulse stockholders even though, a result of such adjustment, the number of
shares of Pulse Common Stock to be issued in the Merger would decrease. In such
a situation, in considering whether to decrease the Exchange Ratio and
consummate the Merger without the resolicitation of Pulse stockholders, the
Pulse Board will take into account, consistent with its fiduciary duties, all
relevant facts and circumstances that exist at such time, including, without
limitation, the advice of its financial advisor and legal counsel. Such
relevant facts and circumstances would include the status of the overall stock
market, the market prices of the stock of comparable financial institutions,
the economy and the performance of Pulse and First Source. See "THE MERGER--
Exchange Ratio" and "--Waiver and Amendment; Termination."

It is intended that George T. Hornyak, Jr., the President and Chief Executive
Officer of Pulse, and Joseph Chadwick, a director of Pulse, will serve as
directors of First Source and First Savings following the Merger pursuant to
the Merger Agreement. Other Pulse directors will receive payments as advisory
directors for a period for three years and certain executive officers will
receive severance payments upon the termination of their employment agreements.
In addition, the Merger Agreement provides that Mr. Hornyak receive a three
year consulting contract with First Source. See "THE MERGER--Interests of

EMPLOYEE MATTERS
 
  The Merger Agreement provides for Pulse employees to participate in the
benefit plans maintained by First Source and provides, in certain instances,
recognition of prior service of Pulse with respect to such participation and
the treatment of Pulse employees following the Merger. See "THE MERGER--
Employee Matters."
 
CONDITIONS; REGULATORY APPROVALS
 
  Consummation of the Merger is subject to various mutual conditions,
including, among others, receipt of the stockholder approvals solicited hereby,
receipt of necessary regulatory approvals, receipt of opinions of counsel
regarding certain federal income tax consequences of the Merger, and the
satisfaction of other customary closing conditions. First Source's obligation
to consummate the Merger is also subject to receipt of a letter from First
Source's independent accountants that the Merger qualifies for pooling of
interests accounting treatment unless such firm advises First Source that it is
unable to issue a letter to such effect solely by reason of First Source having
exercised its rights to purchase Pulse Common Stock pursuant to the Stock
Option Agreement. See "THE MERGER--Conditions to the Merger."
   
  Consummation of the Merger and the transactions contemplated thereby
(including the Subsidiary Bank Merger) are subject to the prior approval of the
Office of Thrift Supervision (the "OTS"), including a waiver of the one-year
OTS restriction on acquisitions by First Source from the date of the April 9,
1998 consummation of the 1998 Conversion and Reorganization, and New Jersey
Department of Banking and Insurance (the "Department"). Applications have been
filed with each of the aforementioned agencies. There can be no assurances when
and if First Source will receive these regulatory approvals or waiver.     
 
WAIVER AND AMENDMENT; TERMINATION
   
  Subject to the terms, conditions and procedures set forth in the Merger
Agreement, both Pulse and First Source may jointly waive compliance with any
provision of the Merger Agreement. The Merger Agreement may be amended by First
Source and Pulse. The Merger Agreement may be terminated in the following ways:
(a) by mutual consent; (b) by either First Source or Pulse after a request or
application for approval has been denied or withdrawn and is not resubmitted,
or a final governmental order is issued that prohibits the Merger, unless the
party seeking to terminate the Merger Agreement is responsible for the denial,
withdrawal or final governmental order; (c) by either First Source or Pulse if
the Merger is not consummated on or before March 31, 1999, unless the delay is
due to a failure by the party seeking to terminate the Merger Agreement to
perform or observe the covenants and provisions of the Merger Agreement; (d) by
either First Source or Pulse if stockholders do not approve the merger; (e) by
either First Source or Pulse (provided that the terminating party has not
materially breached the Merger Agreement) if there has been a material breach
of the Merger Agreement that cannot be readily cured; (f) by Pulse, if the
First Source stock price is less than $8.50 per share, unless First Source
increases the value of consideration to $32.00 per share; (g) by First Source,
if its price is greater than     
 
                                       8
<PAGE>
 
$11.50 per share, unless Pulse permits a decrease in the value of consideration
to $36.80 per share; or (h) by First Source, if the Board of Directors of Pulse
withdraws, modifies or amends its recommendation that stockholders approve and
adopt the Merger Agreement in any respect materially adverse to First Source.
Termination may result in the payment of substantial fees. See "THE MERGER--
Exchange Ratio" and "--Waiver and Amendment; Termination."
 
NO SOLICITATION
 
  Pulse has agreed in the Merger Agreement that neither it nor any of its
subsidiaries will solicit, initiate or encourage inquiries or proposals with
respect to, or, subject to the fiduciary duties of the Pulse Board, participate
in any negotiations or discussions concerning any acquisition or purchase of
all or a substantial portion of its assets, or of a substantial equity interest
in it or any of its subsidiaries, or any merger or other business combination
with it or any of its subsidiaries, other than as contemplated by the Merger
Agreement, except that Pulse may communicate information about any such
proposal to its stockholders if and to the extent that the fiduciary duties of
the Pulse Board require it to do so (as advised by its counsel); Pulse also
agreed in the Merger Agreement that it would immediately cease and cause to be
terminated any existing activities, discussions or negotiations previously
conducted with any parties other than First Source with respect to the
foregoing; it will notify First Source immediately if any such inquiries or
proposals are received by, any such information is requested from, or any such
negotiations or discussions are sought to be initiated with it or any of its
subsidiaries and will promptly inform First Source in writing of the relevant
details with respect to the foregoing; and it will instruct its officers,
directors, agents, advisors and affiliates to comply with the same
restrictions. See "THE MERGER--No Solicitation of Transactions."
 
STOCK EXCHANGE LISTING
 
  First Source Common Stock is listed on The Nasdaq Stock Market. First Source
has agreed to cause the shares of First Source Common Stock to be issued in the
Merger to be approved for listing on The Nasdaq Stock Market. The obligation of
each of Pulse and First Source to consummate the Merger is subject to approval
for listing by The Nasdaq Stock Market of such shares. See "THE MERGER--
Conditions to the Merger."
 
ANTICIPATED ACCOUNTING TREATMENT
 
  The Merger is expected to qualify as a pooling of interests for accounting
and financial reporting purposes. It is a condition to First Source's
obligation to consummate the Merger that it receives a letter from its
independent accountants to the effect that the Merger qualifies for pooling of
interests accounting treatment. See "THE MERGER--Conditions to the Merger" and
"--Anticipated Accounting Treatment."
 
CERTAIN FEDERAL INCOME TAX CONSEQUENCES OF THE MERGER
   
  It is a condition to the obligation of First Savings to consummate the Merger
that First Source and Pulse shall have received an opinion of First Source's
counsel that the Merger and the Subsidiary Bank Merger will each be treated as
reorganizations within the meaning of Section 368(a) of the Internal Revenue
Code of 1986, as amended (the "Code") and, accordingly, for federal income tax
purposes that (i) no gain or loss will be recognized by Pulse as a result of
the Merger; (ii) no gain or loss will be recognized by Pulse Bank as a result
of the Subsidiary Bank Merger, (iii) no gain or loss will be recognized by
First Source as a result of the Merger, (iv) no gain or loss will be recognized
by First Savings as a result of the Subsidiary Bank Merger, (v) no gain or loss
will be recognized by the stockholders of Pulse who exchange all of their Pulse
Common Stock solely for First Source Common Stock pursuant to the Merger
(except with respect to cash received in lieu of a fractional share interest in
First Source Common Stock) and (vi) the aggregate tax basis of First Source
Common Stock received by stockholders who exchange all of their Pulse Common
Stock solely for First Source Common Stock pursuant to the Merger will be the
same as the aggregate tax basis of the Pulse Common Stock surrendered in     
 
                                       9
<PAGE>
 
exchange therefor (reduced by any amount allocable to a fractional share
interest for which cash is received). Each of these conditions is waivable at
the option of the party entitled to receive the requisite opinion.
   
  The holding period for federal income tax purposes of the First Source Common
Stock received by Pulse stockholders pursuant to the Merger will include the
period during which the Pulse Common Stock surrendered therefor was held,
provided the Pulse Common Stock was held as a capital asset on the date of the
Merger. Pulse stockholders are urged to consult their tax advisors with respect
to their personal tax situation and the specific tax consequences to them of
the Merger, including the applicability and effect of various state, local and
foreign tax laws. See "THE MERGER--Certain Federal Income Tax Consequences of
the Merger" and "--Conditions to the Merger."     
 
NO APPRAISAL RIGHTS
 
  No stockholders of Pulse or First Source are entitled to appraisal rights in
connection with, or as a result of, the Merger. See "THE MERGER--No Appraisal
Rights."
 
CONSOLIDATION OF OPERATIONS, PROJECTED COST SAVINGS
 
  First Source expects to achieve significant cost savings subsequent to the
Merger. The cost savings will be derived from implementation of operating
synergies, including reductions in compensation and other employee benefit
expenses. Further, the separate corporate existence of Pulse will cease with
the consummation of the Merger. Consequently, operating costs associated with
requirements imposed on Pulse as a publicly held entity will also be
eliminated. The aggregate annual cost savings are estimated to range between
$2.4 to $2.8 million on a pre-tax basis. Management of First Source believes
that realization of these cost savings will occur by December 31, 1999. There
can be no assurance as to when, or whether, cost savings will be realized.
However, such realization will depend, among other things, upon the regulatory
and economic environment that exists following the Merger, business changes
implemented by First Source management and other factors, many of which are
beyond the control of First Source.
 
MERGER AND RESTRUCTURING CHARGES
   
  A non-recurring merger and restructuring charge estimated in the range of
$5.5 to $5.9 million, before tax effect, will be made upon consummation of the
Merger. It is expected that this charge will be made in the quarter in which
the Merger is consummated. Merger expenses of approximately $1.3 million for
primarily investment banking and professional fees are included in such
estimated restructuring charge. The merger and restructuring charges primarily
include severance and employee related expenses, and, to a lesser extent,
facility and system integration costs and other general costs. See "THE
MERGER--Merger and Restructuring Charges" and""--Certain Federal Income Tax
Consequences of the Merger" and "UNAUDITED PRO FORMA CONDENSED COMBINED
FINANCIAL STATEMENTS."     
 
TERMINATION FEE AND STOCK OPTION AGREEMENT
 
  The inclusion of the provisions in the Merger Agreement relating to the
Termination Fee and the Stock Option Agreement were conditions to First
Source's merger proposal. Pursuant to the Stock Option Agreement, the
provisions of the Merger Agreement relating to the Termination Fee provide that
upon the termination of the Merger Agreement, Pulse will pay First Source $3.2
million, subject to the terms and conditions set forth therein. The Option may
only be exercised, and the Termination Fee is only payable, upon the occurrence
of certain events (none of which has occurred). The aggregate value which First
Source may potentially realize upon exercise of the Option and payment of the
Termination Fee is limited within certain parameters. The Merger Agreement
(which includes the provisions providing for the Termination Fee) is attached
as Annex A to this Joint Proxy Statement/Prospectus. See "CERTAIN RELATED
TRANSACTIONS--Stock Option Agreement; Termination Fee."

  The Termination Fee is intended to increase the likelihood that the Merger
will be consummated in accordance with the terms of the Merger Agreement.
Consequently, certain aspects of the Termination Fee may have the effect of
discouraging persons who might now or prior to the Effective Time be interested
in acquiring all or a significant interest in Pulse from considering or
proposing such an acquisition, even if such persons were prepared to pay a
higher price per share for Pulse Common Stock than the price per share implicit
in the Exchange Ratio.
 
COMPARISON OF STOCKHOLDER RIGHTS
 
  At the Effective Time, Pulse stockholders automatically will become
stockholders of First Source and their rights as stockholders of First Source
will be governed by the Delaware General Corporation Law and by First Source's
Certificate of Incorporation and Bylaws. The rights of stockholders of First
Source differ from the rights of the stockholders of Pulse with respect to
certain matters. For a summary of these differences, see "COMPARISON OF
STOCKHOLDER RIGHTS."

(1) The equivalent price per share of Pulse Common Stock at each specified
    date was determined by multiplying the last reported sale price of a share
    of First Source Common Stock on such date by the Exchange Ratio. For
    purposes of determining the Exchange Ratio, the Average Closing Price was
    assumed to be equal to the last reported sale price of First Source Common
    Stock at each specified date (resulting in an Exchange Ratio of 3.241 on
    July 8, 1998 and 3.710 on October 30, 1998). The actual Exchange Ratio
    will be determined based on the Average Closing Price on the Valuation
    Date.     
 
  Pulse and First Source stockholders are advised to obtain current market
quotations for Pulse Common Stock and First Source Common Stock. The market
price of First Source Common Stock will fluctuate between the date of this
Joint Proxy Statement/Prospectus and the Valuation Date, and between the
Valuation Date and
 
                                      12
<PAGE>
 
the Effective Time. Although the Merger Agreement provides that the Exchange
Ratio will adjust to absorb fluctuations in the market price of First Source
Common Stock within certain ranges prior to the Valuation Date, fluctuations
in such market price prior to the Effective Time could result in an increase
or decrease in the market price as of the Effective Time of the shares of
First Source Common Stock to be received by Pulse stockholders in the Merger.
No assurance can be given concerning the market price of First Source Common
Stock before or after the Effective Time.
 
                  APPROVAL OF THE FIRST SOURCE BANCORP, INC.
                        1998 STOCK-BASED INCENTIVE PLAN
 
  The Board of Directors of First Source is also presenting for stockholder
approval the First Source Bancorp, Inc. 1998 Stock-Based Incentive Plan
("Incentive Plan"), in the form attached hereto as Annex E. The purpose of the
Incentive Plan is to attract and retain qualified personnel in key positions,
provide officers, employees and non-employee directors ("Outside Directors")
with a proprietary interest in First Source as an incentive to contribute to
its success, promote the attention of management to other stockholder's
concerns and reward employees for outstanding performance. The summary of the
material terms of the Incentive Plan is qualified in its entirety by the
complete provisions of the Incentive Plan attached as Annex E. The First
Source Board recommends unanimously that First Source stockholders vote FOR
the approval of the Incentive Plan. See "The First Source Bancorp, Inc. 1998
Stock-Based Incentive Plan."

                            SELECTED FINANCIAL DATA
   
  The following tables set forth selected historical consolidated financial
data for First Source for the five years ended December 31, 1997 and the six
months ended June 30, 1998 and 1997, and for Pulse for the five years ended
September 30, 1997 and the six months ended June 30, 1998 and 1997. Because
Pulse's fiscal year ends on September 30 and First Source's fiscal year ends
on December 31, the financial data for Pulse for the six months ended June 30
has been presented to coincide with the fiscal reporting period for First
Source. Following the Merger, the combined company's fiscal year, like that of
First Source, will end on December 31. The selected data presented in the
tables under the captions "Selected Financial Data" and "Selected Operating
Data" as of and for each of the years in the five year period ended December
31, 1997 as it relates to First Source and September 30, 1997, as it relates
to Pulse have been derived from audited financial statements of First Source
and Pulse. See "INCORPORATION OF CERTAIN DOCUMENTS BY REFERENCE." The
unaudited financial data for the six months ended June 30, 1998 and 1997 for
First Source and Pulse reflects, in the opinions of the management of First
Source and Pulse, respectively, all adjustments necessary for a fair
presentation of such data. Results for the 1998 interim periods are not
necessarily indicative of the results which may be expected for any other
interim period or for the year as a whole.

             UNAUDITED PRO FORMA COMBINED SELECTED FINANCIAL DATA
   
  The following tables set forth certain selected condensed financial data for
First Source and Pulse on an unaudited pro forma combined basis giving effect
to the Merger as if the Merger had become effective on June 30, 1998, in the
case of the balance sheet data presented, and if the Merger had become
effective at the beginning of the periods indicated, in the case of the income
statement data presented. The pro forma data in the tables assume that the
Merger is accounted for using the pooling of interests method of accounting.
See "THE MERGER--Anticipated Accounting Treatment." The unaudited pro forma
combined condensed selected year-end balance sheet data reflect First Source
and Pulse at their respective year-end reporting periods of December 31 and
September 30 and for the periods then ended for the income statement data.
Because Pulse's fiscal year ends on September 30 and First Source's fiscal
year ends on December 31, financial data for the six months ended June 30,
1998 and 1997 combine First Source's with Pulse's interim results to coincide
with the reporting periods for First Source. Following the Merger, the
combined company's fiscal year, like that of First Source, will end on
December 31. These tables should be read in conjunction with, and are
qualified in their entirety by, the historical financial statements, including
the notes thereto, of First Source and Pulse incorporated by reference herein
and the more detailed pro forma financial information, including the notes
thereto, appearing elsewhere in this Joint Proxy Statement/Prospectus. Certain
Pulse financial information has been restated to conform with that of First
Source. See "INCORPORATION OF CERTAIN DOCUMENTS BY REFERENCE" and "UNAUDITED
PRO FORMA CONDENSED COMBINED FINANCIAL STATEMENTS."     
 
  The pro forma data and ratios set forth in the following tables do not
reflect the expected cost savings and revenue enhancement opportunities that
could result from the Merger or any other items of income or expense which may
result from the Merger. The pro forma balance sheet data and certain ratios do
reflect a $4.1 million reduction to stockholders' equity at June 30, 1998,
which represents the estimated cost of merger expenses and restructuring
charges, net of tax. The unaudited pro forma combined selected financial data
is presented for informational purposes only and is not necessarily indicative
of the combined financial position or results of operations that would have
occurred if the Merger had been consummated on June 30, 1998, or at the
beginning of the periods indicated or which may be obtained in the future.

(1) The table sets forth unaudited pro forma combined selected financial data
    for First Source and Pulse. The historical data has been derived from the
    financial statements of First Source and Pulse which are incorporated by
    reference herein. The pro forma combined share data have been derived
    after giving effect to the Merger as if it occurred at the beginning of
    the period presented using the pooling-of-interest method of accounting.
    Under a pooling-of-interest method, a business combination is accounted as
    the uniting of the ownership interests of two or more enterprises through
    an exchange of equity interests. The assets and liabilities of Pulse are
    carried forward to First Source at their recorded amounts. The income of
    the First Source and Pulse, for the current period and all prior periods,
    is combined and reported as income of the combined enterprise.     
 
(2)  Includes federal funds sold and investment in the stock of FHLB-NY.
   
(3)  Reflects the implementation of SFAS No. 106--Accounting for Post-
     Retirement Benefits and SFAS No. 109--Accounting for Income Taxes.     
   
(4) Includes the effect of non-recurring items in 1997 and 1996. Non-recurring
    items for 1997 included a writedown of the core deposit goodwill totaling
    $1.3 million, or $867,000 net of tax. Non-recurring items for 1996
    included the SAIF assessment of $7.9 million, or $5.0 million net of tax,
    a writedown of the $334,000 of core deposit goodwill, and a provision for
    benefits payable as a result of the passing of First Savings' long-time
    President.     
   
(5)  Annualized for the six months ended June 30, 1998 and 1997 for
     comparability.     
          
(6)  Calculation is based upon the net interest income before provision for
     loan losses divided by average interest-earning assets.     
   
(7) For purposes of calculating these ratios, operating expenses is equal to
    total operating expenses less amortization of intangibles.

                                 THE MEETINGS
 
PULSE MEETING
   
  General. This Joint Proxy Statement/Prospectus is being furnished to
stockholders of Pulse in connection with the solicitation of proxies by the
Pulse Board for use at the Pulse Meeting and at any adjournments or
postponements thereof to be held at the Holiday Inn, Forsgate Drive,
Jamesburg, New Jersey, on Wednesday, December 16, 1998, at 9:00 a.m. local
time. At the Pulse Meeting, the stockholders of Pulse will be asked to:
(i) approve and adopt the Merger Agreement between First Source and Pulse and
the consummation of the transactions contemplated thereby, which are more
fully described herein; and (ii) act upon such other matters as may properly
be brought before the Pulse Meeting and at any adjournments or postponements
thereof. A copy of the Merger Agreement is attached as Annex A hereto. The
Merger Agreement provides for the acquisition of Pulse by First Source by
means of the merger of Pulse with and into First Source. Upon consummation of
the Merger, each share of the Pulse Common Stock outstanding on the date of
the Merger (except for certain specified shares described below) will be
converted into and exchangeable for the number of shares of First Source
Common Stock equal to the Exchange Ratio. See "THE MERGER--Exchange Ratio."
    
  This Joint Proxy Statement/Prospectus constitutes a prospectus of First
Source with respect to the shares of First Source Common Stock to be issued in
connection with the Merger. The information in this Joint Proxy
Statement/Prospectus concerning First Source and Pulse has been furnished by
each of such entities, respectively.
 
  HOLDERS OF PULSE COMMON STOCK ARE REQUESTED TO PROMPTLY COMPLETE, SIGN AND
DATE THE ACCOMPANYING PROXY CARD AND RETURN IT PROMPTLY TO PULSE IN THE
ENCLOSED POSTAGE-PAID ADDRESSED ENVELOPE.
 
  PULSE STOCKHOLDERS SHOULD NOT FORWARD ANY STOCK CERTIFICATES WITH THEIR
PROXY CARDS.
 
  Recommendation of the Board of Directors. The Pulse Board has unanimously
approved the Merger Agreement and has determined that the Merger is fair to,
and in the best interests of, Pulse and its stockholders. The Pulse Board
therefore unanimously recommends that Pulse's stockholders vote FOR approval
of the Merger Agreement. See "THE MERGER--Background of the Merger" and "--
Recommendation of the Boards of Directors; Reasons for the Merger--Pulse."
   
  Record Date; Voting; Solicitation and Revocation of Proxies. The Pulse Board
has fixed October 30, 1998 as the Pulse Record Date for the determination of
those Pulse stockholders entitled to notice of and to vote at the Pulse
Meeting. Only holders of record of Pulse Common Stock at the close of business
on the Pulse Record Date will be entitled to notice of and to vote at the
Pulse Meeting. As of the Pulse Record Date, there were 3,205,800 shares of
Pulse Common Stock outstanding, entitled to vote and held by approximately 800
holders of record. Each holder of record of shares of Pulse Common Stock on
the Pulse Record Date is entitled to cast one vote per share on the proposal
to approve and adopt the Merger Agreement, and on any other matter properly
submitted for the vote of the Pulse stockholders at the Pulse Meeting. The
presence, either in person or by properly executed proxy, of the holders of a
majority of the outstanding shares of Pulse Common Stock entitled to vote at
the Pulse Meeting is necessary to constitute a quorum at the Pulse Meeting.
Abstentions will be counted as present for purposes of determining the
presence or absence of a quorum at the Pulse Meeting.     
 
  The approval and adoption of the Merger Agreement by Pulse stockholders will
require the affirmative vote of the holders of a majority of the outstanding
shares of Pulse Common Stock entitled to vote thereon. As described in "THE
MERGER--Conditions to the Merger," such stockholder approval is a condition to
consummation of the Merger. Under applicable New Jersey law, in determining
whether the Merger proposal has received the requisite number of affirmative
votes, abstentions and broker non-votes will be counted and will have the same
effect as a vote against the proposal to approve and adopt the Merger
Agreement.
 
                                      23

  As of the Pulse Record Date, directors and executive officers of Pulse and
their affiliates may be deemed to be beneficial owners of 639,641 shares,
including outstanding options to purchase Pulse Common Stock held by such
individuals, or approximately 19.0% of the shares, of Pulse Common Stock
outstanding as of the Record Date. Such persons have informed Pulse that they
intend to vote or direct the vote of all such shares of Pulse Common Stock FOR
approval and adoption of the Merger Agreement and the transactions
contemplated thereby. As of the Pulse Record Date, First Source and its
subsidiary, including the directors and executive officers of First Source,
beneficially owned 200 shares of Pulse Common Stock.     
 
  All shares of Pulse Common Stock which are entitled to be voted and are
represented at the Pulse Meeting by properly executed proxies received prior
to or at the meeting, and not revoked, will be voted at such meeting, and any
adjournments or postponements thereof, in accordance with the instructions
indicated on such proxies. If no instructions are indicated, such proxies will
be voted FOR: (i) approval and adoption of the Merger Agreement, and (ii)
otherwise in the discretion of the proxy holders as to any other matter which
may come before the Pulse Meeting or any adjournment or postponement thereof,
including, among other things, a motion to adjourn or postpone the Pulse
Meeting to another time and/or place, for the purpose of soliciting additional
proxies or otherwise; provided, however, that no proxy which is voted against
the proposal to approve and adopt the Merger Agreement will be voted in favor
of any such adjournment or postponement.
 
  If any other matters are properly presented at the Pulse Meeting for
consideration, the persons named in the form of proxy enclosed herewith and
acting thereunder will have discretionary authority to vote on such matters in
accordance with their best judgment; provided, however, that such
discretionary authority will only be exercised to the extent possible under
applicable federal and state securities and corporation laws. Pulse does not
have any knowledge of any matters to be presented at the Pulse Meeting other
than the matters set forth above.
 
  Any proxy given by a Pulse stockholder pursuant to this solicitation may be
revoked by the person giving it at any time before it is voted. Proxies may be
revoked by (i) filing with the Secretary of Pulse, at or before the taking of
the vote at the Pulse Meeting, a written notice of revocation bearing a later
date than the proxy, (ii) duly executing a later-dated proxy relating to the
same shares and delivering it to the Secretary of Pulse before the taking of
the vote at the Pulse Meeting, or (iii) attending the Pulse Meeting and voting
in person (although attendance at the meeting will not in and of itself
constitute a revocation of a proxy). Any written notice of revocation or
subsequently executed proxy should be sent so as to be delivered to Pulse
Bancorp, Inc., 6 Jackson Street, South River, New Jersey 08882, Attention:
Nancy M. Janosko, Secretary, or hand delivered to Ms. Janosko at or before the
taking of the vote at the Pulse Meeting.
   
  Pulse will bear all expenses of this solicitation of proxies from the
holders of Pulse Common Stock, except that the cost of preparing and mailing
this Joint Proxy Statement/Prospectus will be borne equally by Pulse and First
Source. In addition to solicitation by use of the mails, proxies may be
solicited by directors, officers and employees of Pulse in person or by
telephone, telegram or other means of communication. Such directors, officers
and employees will not be additionally compensated, but may be reimbursed for
reasonable out-of-pocket expenses in connection with such solicitation. Pulse
has retained Kissel-Blake, Inc., to assist in such solicitation. The fee to be
paid to such firm is not expected to exceed $4,000 plus reasonable out-of-
pocket costs and expenses. Kissel-Blake will make arrangements with brokerage
firms and other custodians, nominees and fiduciaries to send proxy materials
to their principals and will reimburse such parties for their expenses in
doing so.

  HOLDERS OF FIRST SOURCE COMMON STOCK ARE REQUESTED TO PROMPTLY COMPLETE,
SIGN AND DATE THE ACCOMPANYING PROXY CARD AND RETURN IT PROMPTLY TO FIRST
SOURCE IN THE ENCLOSED POSTAGE-PAID ADDRESSED ENVELOPE.
   
  FIRST SOURCE STOCKHOLDERS SHOULD NOT FORWARD ANY STOCK CERTIFICATES.     
   
  Recommendation of the Board of Directors. The First Source Board has
unanimously approved the Merger Agreement and has determined that the Merger
is fair to, and in the best interests of, First Source and its stockholders.
The First Source Board therefore unanimously recommends that First Source's
stockholders vote FOR approval of the Merger Agreement. The First Source board
has also unanimously approved the Incentive Plan and the Corporate Name
Amendment and unanimously recommends that First Source's stockholders vote FOR
approval and adoption of the Incentive Plan and the Corporate Name Amendment.
See "THE MERGER--Background of the Merger" and "--Recommendation of the Boards
of Directors; Reasons for the Merger--First Source"; "The First Source
Bancorp, Inc. 1998 Stock-Based Incentive Plan"; and "Amendment of the First
Source Bancorp, Inc. Certificate of Incorporation."     
   
  Record Date; Voting; Solicitation and Revocation of Proxies. The First
Source Board has fixed October 30, 1998 as the First Source Record Date for
the determination of those First Source stockholders entitled to notice of and
to vote at the First Source Meeting. Only holders of record of First Source
Common Stock at the close of business on the First Source Record Date will be
entitled to notice of and to vote at the First Source Meeting. As of the First
Source Record Date, there were 31,838,866 shares of First Source Common Stock
outstanding, held by approximately 2,667 holders of record. Each holder of
record of shares of First Source Common Stock on the First Source Record Date
is entitled to cast one vote per share on the proposals to approve and adopt
the Merger Agreement, the Incentive Plan and the Corporate Name Amendment and
on any other matter properly submitted for the vote of the First Source
stockholders at the First Source Meeting. The presence, either in person or by
properly executed proxy, of the holders of a majority of the outstanding
shares of First Source Common Stock entitled to vote at the First Source
Meeting is necessary to constitute a quorum at the First Source Meeting.
Abstentions will be counted as present for purposes of determining the
presence or absence of a quorum at the First Source Meeting.     
   
  The approval and adoption of the Merger Agreement by First Source
stockholders will require the affirmative vote of the holders of a majority of
the outstanding shares of First Source Common Stock entitled to vote thereon.
As described in "THE MERGER--Conditions to the Merger," such stockholder
approval is a condition to consummation of the Merger. The approval and
adoption of the Incentive Plan and the Corporate Name Amendment will also
require the affirmative vote of the holders of a majority of the outstanding
shares of First Source Common Stock entitled to vote thereon. Under applicable
Delaware law, in determining whether the Merger, the Incentive Plan and the
Corporate Name Amendment proposals have received the requisite number of
affirmative votes, abstentions and broker non-votes will be counted and will
have the same effect as a vote against the proposals presented.     
   
  As of the First Source Record Date, directors and executive officers of
First Source and their affiliates may be deemed to be beneficial owners of
3,468,147 shares of First Source Common Stock, or approximately 10.89% of the
shares of First Source Common Stock outstanding as of the Record Date. Such
persons have informed First Source that they intend to vote or direct the vote
of all such shares of First Source Common Stock FOR approval and adoption of
the Merger Agreement, approval and adoption of the Incentive Plan, approval
and adoption of the Corporate Name Amendment and the transactions contemplated
thereby. As of the First Source Record Date, Pulse and the directors and
executive officers of Pulse, beneficially owned 14,229  shares of First Source
Common Stock.     
 
                                      25
<PAGE>
 
  All shares of First Source Common Stock which are entitled to be voted and
are represented at the First Source Meeting by properly executed proxies
received prior to or at the meeting, and not revoked, will be voted at such
meeting, and any adjournments or postponements thereof, in accordance with the
instructions indicated on such proxies. If no instructions are indicated, such
proxies will be voted FOR: (i) approval and adoption of the Merger Agreement;
(ii) approval and adoption of the Incentive Plan; (iii) approval and adoption
of the Corporate Name Amendment; and (iv) otherwise in the discretion of the
proxy holders as to any other matter which may come before the First Source
Meeting or any adjournment or postponement thereof, including, among other
things, a motion to adjourn or postpone the First Source Meeting to another
time and/or place, for the purpose of soliciting additional proxies or
otherwise; provided, however, that no proxy which is voted against the
proposals will be voted in favor of any such adjournment or postponement.
 
  If any other matters are properly presented at the First Source Meeting for
consideration, the persons named in the form of proxy enclosed herewith and
acting thereunder will have discretionary authority to vote on such matters in
accordance with their best judgment; provided, however, that such
discretionary authority will only be exercised to the extent possible under
applicable federal and state securities and corporation laws. First Source
does not have any knowledge of any matters to be presented at the First Source
Meeting other than the matters set forth above.
   
  Any proxy given by a First Source stockholder pursuant to this solicitation
may be revoked by the person giving it at any time before it is voted. Proxies
may be revoked by: (i) filing with the Secretary of First Source, at or before
the taking of the vote at the First Source Meeting, a written notice of
revocation bearing a later date than the proxy; (ii) duly executing a later
dated proxy relating to the same shares and delivering it to the Secretary of
First Source before the taking of the vote at the First Source Meeting; or
(iii) attending the First Source Meeting and voting in person (although
attendance at the meeting will not in and of itself constitute a revocation of
a proxy). Any written notice of revocation or subsequently executed proxy
should be sent to First Source Bancorp, Inc., 1000 Woodbridge Center Drive,
Woodbridge, NJ 07095, Attention: Christopher Martin, Corporate Secretary, or
hand delivered to Mr. Martin at such address at or before the taking of the
vote at the First Source Meeting.     
   
  First Source will bear all expenses of this solicitation of proxies from the
holders of First Source Common Stock, except that the cost of preparing and
mailing this Joint Proxy Statement/Prospectus will be borne equally by Pulse
and First Source. In addition to solicitation by use of the mails, proxies may
be solicited by directors, officers and employees of First Source in person or
by telephone, telegram or other means of communication. Such directors,
officers and employees will not be additionally compensated, but may be
reimbursed for reasonable out-of-pocket expenses in connection with such
solicitation. First Source has retained Kissel-Blake, Inc., a proxy soliciting
firm, to assist in such solicitation. The fee to be paid to such firm is not
expected to exceed $6,000 plus reasonable out-of-pocket costs and expenses. In
addition, Kissel-Blake, Inc. will make arrangements with brokerage firms and
other custodians, nominees and fiduciaries to send proxy materials to their
principals and will reimburse such parties for their expenses in doing so.

                                  THE MERGER
 
  The following information concerning the Merger, insofar as it relates to
matters contained in the Merger Agreement, describes the material aspects of
the Merger but does not purport to be a complete description and is qualified
in its entirety by reference to the Merger Agreement which is incorporated
herein by reference and attached hereto as Annex A. First Source and Pulse
stockholders are urged to read carefully the Merger Agreement.
 
GENERAL
 
  Pursuant to the terms of the Merger Agreement, subject to the satisfaction
or waiver (where permissible) of certain conditions, including, among other
things, the receipt of all necessary regulatory approvals, the expiration of
all waiting periods in respect thereof, and the approval of the Merger
Agreement by the requisite vote of the stockholders of First Source and Pulse,
Pulse will be merged with and into First Source. First Source shall be the
surviving corporation in the Merger, and shall continue its corporate
existence under the laws of the State of Delaware. Upon consummation of the
Merger, the separate corporate existence of Pulse shall terminate.
   
  Immediately after the consummation of the Merger, Pulse Bank, a New Jersey
stock savings bank and a wholly-owned subsidiary of Pulse, will merge (the
"Subsidiary Bank Merger") with and into First Savings, a New Jersey savings
and loan association and a wholly-owned subsidiary of First Source. See
"CERTAIN RELATED TRANSACTIONS--Subsidiary Bank Merger Agreement."     
 
EXCHANGE RATIO
   
  At the Effective Time, each issued and outstanding share of Pulse Common
Stock, except for shares held directly or indirectly by Pulse or First Source
(other than Trust Account Shares and DPC Shares), will be converted into and
exchangeable for the number of shares of First Source Common Stock determined
as follows: (i) subject to certain provisions of the Agreement, if the Average
Closing Price of First Source Common Stock is equal to or greater than $11.50,
the Exchange Ratio shall be equal to 3.2; (ii) if the Average Closing Price is
$10.00 or greater but less than $11.50, the Exchange Ratio shall be 3.2; (iii)
if the Average Closing Price is greater than $8.50 but less than $10.00, the
Exchange Ratio shall equal $32.00 divided by the Average Closing Price; or
(iv) subject to certain provisions of the Agreement, if the Average Closing
Price is equal to or less than $8.50, the Exchange Ratio shall be 3.764. The
Average Closing Price is defined as the average closing sales price of the
First Source Common Stock on the Nasdaq Stock Market for the 10 consecutive
trading days ending on the fifth business day (the "Valuation Date") prior to
the date on which the later of approval of First Source's stockholders,
Pulse's Stockholders, or the date the last required regulatory approval for
the Merger and the other transactions contemplated by the Merger Agreement is
obtained, without regard to any requisite waiting periods in respect thereof.
Under the terms of the Merger Agreement, cash will be paid in lieu of the
issuance of fractional shares of First Source Common Stock.     
   
  If the Average Closing Price is less than $8.50 and, in response to an
election by Pulse to terminate the Merger Agreement, First Source elects to
increase the Exchange Ratio, First Source will exchange $32.00 of First Source
Common Stock for each share of Pulse Common Stock. See "--Waiver and
Amendment; Termination" below. Assuming the Merger is approved by the holders
of Pulse Common Stock, the Pulse Board may elect not to terminate the Merger
Agreement and to consummate the Merger without resoliciting Pulse stockholders
if the Average Closing Price is less than $8.50, even though, as a result of
the application of the Exchange Ratio, the value of the shares of First Source
Common Stock (valued at the Average Closing Price) issued in exchange for each
share of Pulse Common Stock would be less than $32.00. In such a situation, in
considering whether to consummate the Merger without the resolicitation of
Pulse stockholders, the Pulse Board will take into account, consistent with
its fiduciary duties, all relevant facts and circumstances that exist at such
time, including, without limitation, its evaluation of the then-existing
economic conditions and trends, its     
 
                                      27
<PAGE>
 
evaluation of the respective business, financial condition, results of
operations and prospects of each of Pulse and First Source, its evaluation of
the overall condition of the thrift and commercial banking industries and the
advice of its financial advisor and legal counsel. Pulse stockholders will
have no vote in the decision of the Pulse Board to either terminate the Merger
Agreement or elect to consummate the Merger in the event that the Average
Closing Price is less than $8.50. See "--Waiver and Amendment; Termination"
below.
 
  Assuming the Merger is approved by the holders of First Source Common Stock
and the Average Closing Price is less than $8.50, the First Source Board may
elect to increase the Exchange Ratio and to consummate the Merger without
resoliciting First Source stockholders even though, as a result of such
adjustment, the number of shares of First Source Common Stock to be issued in
the Merger would increase. In such a situation, in considering whether to
increase the Exchange Ratio and consummate the Merger without the
resolicitation of First Source stockholders, the First Source Board will take
into account, consistent with its fiduciary duties, all relevant facts and
circumstances that exist at such time, including, without limitation, the
advice of its financial advisor and legal counsel. Such relevant facts and
circumstances would include the First Source Board's evaluation of the
dilutive impact of a higher Exchange Ratio to First Source's stockholders, its
evaluation of the strategic importance to First Source of the acquisition of
Pulse relative to any such dilutive impact and the accretive prospects of the
acquisition, its evaluation of the synergies of Pulse's business relative to
First Source, Pulse's financial condition, operating performance, and
prospects, and the advice of First Source's financial advisor as to the
fairness of such higher Exchange Ratio to First Source stockholders from a
financial point of view. First Source stockholders will have no vote in the
decision of the First Source Board to either permit Pulse to terminate the
Merger Agreement or elect to increase the Exchange Ratio in the event that the
Average Closing Price is less than $8.50.
   
  First Source has the right to terminate the Agreement if the Average Closing
Price of First Source is greater than $11.50 per share, unless Pulse provides
notice pursuant to the Agreement that it wants to proceed with the Merger, in
which event First Source will exchange $36.80 of First Source Common Stock for
each share of Pulse Common Stock. Assuming the Merger is approved by First
Source stockholders, the First Source Board may elect not to terminate the
Merger Agreement and to consummate the Merger without resoliciting First
Source stockholders if the Average Closing Price is greater than $11.50 and
Pulse chooses not to decrease the consideration, even though, as a result of
the application of the Exchange Ratio, the value of the shares of First Source
Common Stock (valued at the Average Closing Price) issued in exchange for each
share of Pulse Common Stock would be greater that $36.80. In such a situation,
in considering whether to consummate the Merger without the resolicitation of
First Source stockholders, the First Source Board will take into account,
consistent with its fiduciary duties, all relevant facts and circumstances
that exist at such time including, without limitation, its evaluation of the
then-existing economic conditions and trends, its evaluation of the respective
business, financial condition, results of operations and prospects of each of
Pulse and First Source, its evaluation of the overall condition of the thrift
and commercial banking industry and the advice of its financial advisor and
legal counsel.     
   
  Assuming the Merger is approved by the holders of Pulse Common Stock and the
Average Closing Price is greater than $11.50, the Pulse Board may elect to
decrease the Exchange Ratio and to consummate the Merger without resoliciting
Pulse stockholders even though, a result of such adjustment, the number of
shares of First Source Common Stock to be issued in the Merger would decrease.
In such a situation, in considering whether to decrease the Exchange Ratio and
consummate the Merger without the resolicitation of Pulse stockholders, the
Pulse Board will take into account, consistent with its fiduciary duties, all
relevant facts and circumstances that exist at such time, including, without
limitation, the advice of its financial advisor and legal counsel. Such
relevant facts and circumstances would include the status of the overall stock
market, the market prices of stock of comparable financial institutions, the
economy and the performance of Pulse and First Source. See "THE MERGER--
Exchange Ratio" and "--Waiver and Amendment; Termination."     
 
  The formula for determining the Exchange Ratio was arrived at through arms-
length negotiations between Pulse and First Source. If First Source effects a
stock dividend, split-up or combination, or other distribution in First Source
Common Stock prior to consummation of the Merger, an appropriate adjustment to
the Exchange Ratio will be made.
 
                                      28
<PAGE>
 
   
  Under the terms of the Merger Agreement, the Exchange Ratio will be
determined by reference to the Average Closing Price of First Source Common
Stock as of the Valuation Date. Due to the requirements of applicable law,
among other reasons, it is possible that the Valuation Date will occur 30 days
or more prior to the Effective Time. The market price of First Source Common
Stock will fluctuate between the date of this Joint Proxy Statement/Prospectus
and the Valuation Date, and between the Valuation Date and the Effective Time.
Although the Merger Agreement provides that the Exchange Ratio will adjust to
absorb fluctuations in the market price of First Source Common Stock within
certain ranges prior to the Valuation Date, fluctuations in such market price
prior to the Effective Time could result in an increase or decrease in the
market price as of the Effective Time of the shares of First Source Common
Stock to be received by Pulse stockholders in the Merger. If the Valuation
Date had been October 30, 1998, the Exchange Ratio would have been 3.710. For
further information concerning the market prices of First Source Common Stock
and Pulse Common Stock, see "MARKET PRICES AND DIVIDEND INFORMATION." No
assurance can be given concerning the market price of First Source Common
Stock before or after the Effective Time.     
 
  No fractional shares of First Source Common Stock will be issued in
connection with the Merger. In lieu of the issuance of fractional shares,
First Source will make a cash payment to each Pulse stockholder who otherwise
would be entitled to receive a fractional share equal to the product of (i)
the fractional interest which a Pulse stockholder would otherwise receive and
(ii) the average of the closing sale prices of First Source Common Stock on
the Nasdaq National Market for the five trading days immediately preceding the
Effective Time.
   
  Upon consummation of the Merger, any shares of Pulse Common Stock that were
owned by Pulse as treasury stock or that were held directly or indirectly by
First Source other than Trust Account Shares and DPC Shares will be canceled
and retired and no payment will be made with respect thereto.     
   
  Based on the outstanding shares of First Source and Pulse as of October 30,
1998, upon consummation of the Merger, the stockholders of Pulse will own
First Source Common Stock representing approximately 26.8% of the outstanding
First Source Common Stock following the Merger assuming an Exchange Ratio of
3.710. As more fully described above, the Exchange Ratio could be as low as
3.2 and as high as 3.764. Such percentages would range from 24.0% to 27.1%,
depending on whether the shares of Pulse Common Stock and First Source Common
Stock issuable upon exercise of outstanding Pulse stock options and First
Source stock options and warrants (vested and unvested) are issued. For
purposes of these calculations, except as set forth above, it is assumed that
no other shares of First Source Common Stock and Pulse Common Stock are
issued.     
   
  If the Merger had been consummated on September 30, 1998, First Source and
Pulse would have accounted for 69.0% and 31.0%, respectively, of the revenue
of the combined entity. Further, First Source and Pulse would have represented
70.2% and 29.8%, respectively, of the total assets and 84.6% and 15.4%,
respectively, of the stockholders' equity of the combined company. Such
amounts exclude consideration of merger and restructuring charges expected to
be made in connection with the Merger.     
   
  In addition, at the Effective Time, each outstanding and unexercised option
to purchase shares of Pulse Common Stock (a "Pulse Option") will either be
assumed by First Source or converted into shares of First Source pursuant to a
formula described below. If the Pulse options are converted into First Source
options, after the Effective Time, each Pulse Option will be deemed to
constitute an option to acquire, on the same terms and conditions as were
applicable under such Pulse Option immediately prior to the Effective Time,
the number of shares of First Source Common Stock equal to the product,
rounded down to the nearest share, of the number of shares of Pulse Common
Stock subject to the Pulse Option and the Exchange Ratio, at a price per share
equal to the exercise price per share of Pulse Common Stock otherwise
purchasable pursuant to such Pulse Option divided by the Exchange Ratio,
rounded up to the nearest cent. If the Pulse options are converted into First

BACKGROUND OF THE MERGER
 
  Pulse is a unitary savings and loan holding company that is chartered by the
State of New Jersey. In 1990, Pulse exchanged its common stock for all of the
issued and outstanding common stock of a predecessor of Pulse Savings Bank.
The common stock of this predecessor, first chartered as a mutual institution
in 1916, had been issued in 1986. Pulse directs and plans the activities of
Pulse Bank, Pulse's primary asset. Pulse Bank is a New Jersey-chartered
capital stock savings bank headquartered in South River, New Jersey.
   
  In connection with its normal strategic review, Pulse regularly examines its
strategic business alternatives, devoting particular attention to the
continuing consolidation and increasing competition in the banking and
financial services industries in the New Jersey market. The New Jersey market
is home to many large, aggressive regional commercial banking entities, and
the banking market in New Jersey in particular has been subject to significant
consolidation in recent years. As a result, competition in the local banking
and financial services industries has intensified, especially for smaller
thrift institutions like Pulse. This review by Pulse has included, from time
to time, presentations to the Pulse board of directors from investment banking
firms, including Sandler O'Neill. These presentations have included an
overview of the market for bank and thrift mergers, an assessment of Pulse's
then current strategic business plan, and a preliminary estimate of Pulse's
market value were it to pursue a strategic merger transaction. The President
of Pulse (Mr. Hornyak) and several of the members of the board of directors of
Pulse, were aware during the month of May 1998 that the stock prices of
certain thrift institutions in New Jersey had dropped, or failed to rise (as
had been typical), following their recent conversions from the mutual holding
company structure to a stock holding company structure.     
   
  During early June 1998, Mr. Hornyak was approached by Ryan, Beck, an
investment banker, which informed Mr. Hornyak that a financial institution
located in New Jersey was interested in discussing the possibility of pursuing
a negotiated merger with Pulse. Mr. Hornyak advised Ryan, Beck that Pulse was
not inclined to pursue a merger but agreed with Ryan, Beck that the recent
drop in share price for certain thrift institutions could present an
opportunity for Pulse if the consideration to be received by Pulse was based
on the then current share price of such a thrift institution as the potential
acquiror.     
   
  Following that discussion, in mid-June 1998, Mr. Hornyak advised the members
of the board of directors about his discussions with Ryan, Beck and that there
was an opportunity for shareholders of Pulse to realize value in exchanging
shares of Pulse for what could be relatively low priced shares of an acquiror.
Mr. Hornyak was informally advised by the members of the board of directors to
pursue his discussions. Mr. Hornyak did so and was told by Ryan, Beck that
First Source was the interested party. During the second half of June 1998, an
outline of terms was discussed with the Pulse Board of Directors, First Source
and Ryan, Beck. On June 23, 1998, with counsel present, a special meeting of
the Pulse board of directors was held to discuss the proposed terms of the
potential merger that management and certain directors had drafted. Discussion
at this meeting included the consideration received in recent merger
transactions as well as consideration that had been offered to Pulse in the
past several years during its exploration of its potential value in a merger.
The Board of Directors considered the relative merits in a tax free merger of
exchanging Pulse shares for either relatively high priced shares (on a book
value per share basis) of other financial institutions or for relatively low
priced shares (on a book value per share basis) of an institution such as
First Source. The market value of thrift institutions, such as First Source,
that had recently completed the conversion from mutual holding company to
stock form was evaluated, as was the value to Pulse of merging with another
thrift institution located in the same market area of Middlesex County, New
Jersey. At this meeting, counsel and the Board of Directors discussed
termination fees and lock-up options at great length, as well as accounting
and tax issues, and treatment of employee and other plans and other potential
impacts on Pulse. Between June 23 and 25, 1998, discussions between the
parties continued with additional revisions to the proposed terms. A regular
meeting of the Pulse Board of Directors was held on June 25, 1998. At this
meeting, the Board of Directors continued its discussion of many of the issues
discussed on June 23, 1998 and the revised terms were discussed and further
revised. Management was     
 
                                      30
<PAGE>
 
authorized on June 25, 1998 to submit a list of terms to First Source and, if
accepted by First Source, to begin a review of the operations of First Source
and negotiate a merger agreement, lock-up option and related documents.
   
  During the remainder of June 1998 and during the early part of July 1998,
the form and amount of consideration, the Exchange Ratio, the treatment of
Pulse stock options, the termination provisions, and issues relating to the
management and operations of Pulse and Pulse Bank following the Merger were
determined on the basis of arms-length-negotiation between Pulse
representatives and the First Source representatives and agreement on other
proposed terms was reached. Pulse began to interview management of First
Source and examine documents. In early July 1998, because of Pulse's long term
relationship with Sandler O'Neill, Sandler O'Neill was engaged to render a
fairness opinion with respect to the Exchange Ratio. Pulse, First Source,
their respective legal counsel and Ryan, Beck conducted reciprocal due
diligence analyses.     
   
  During early July 1998, negotiations continued, members of the Board of
Directors of Pulse discussed the drafts of the merger agreement and Pulse's
counsel and accountants were consulted about various aspects of the proposed
merger. During this time Mr. Hornyak continued to confer with members of the
Board of Directors.     
   
  On July 9, 1998, the Pulse Board of Directors held a special meeting to
discuss the Merger Agreement and other aspects of the Merger. At that meeting,
the reasons for, and the potential benefits of the Merger were discussed;
Pulse's legal counsel reviewed the terms of the Merger Agreement, related
agreements and the transactions contemplated thereby and final revisions to
the Merger Agreement were made. At that meeting, Sandler O'Neill also made a
presentation to the Board of Directors and rendered its opinion as to the
fairness, from a financial point of view, of the Exchange Ratio to holders of
Pulse Common Stock. After a thorough discussion and consideration of the
factors discussed below under "The Merger--Recommendation of the Boards of
Directors; Reasons for the Merger" the Pulse Board of Directors unanimously
approved the Merger Agreement and the transactions contemplated in the Merger
Agreement as in the best interests of Pulse and its stockholders, and
authorized the execution of the Merger Agreement. The Merger Agreement was
entered into on July 9, 1998.     
 
RECOMMENDATION OF THE BOARDS OF DIRECTORS; REASONS FOR THE MERGER
   
  Pulse. In reaching its decision to approve the Merger Agreement, the Pulse
Board considered a number of factors. The Pulse Board did not assign any
relative or specific weights to the factors considered. Among other things,
the Pulse Board considered: (i) the Merger consideration in relation to the
book value, assets and earnings of Pulse; (ii) information concerning the
financial condition, results of operations and prospects of First Source and
Pulse including the return on the assets and return on equity of the
respective companies; (iii) the financial terms of other recent business
combinations in the banking industry; and (iv) the opinion of Sandler O'Neill
as to the fairness of the Exchange Ratio, as of such date, to Pulse
stockholders from a financial point of view.     
   
  The Pulse Board believes that the terms of the Merger Agreement, which are
the product of arms-length negotiations between First Source and Pulse, are in
the best interest of Pulse and its stockholders. In the course of reaching its
determination, the Pulse Board consulted with its legal counsel with respect
to its legal duties, the terms of the Merger Agreement and the issues related
thereto; and with senior management regarding, among other things, operational
matters.     
 
  In reaching its determination to approve the Merger Agreement, the Pulse
Board also considered the following factors:
 
    (a) The Pulse Board analyzed information with respect to the financial
  condition, results of operations, business and prospects of First Source
  and Pulse.
 
                                      31
<PAGE>
 
    (b) The Pulse Board considered the written opinion of Sandler O'Neill
  that as of July 9, 1998, the Exchange Ratio was fair to Pulse shareholders
  from a financial point of view. See "--Opinion of Pulse's Financial
  Advisor."
 
    (c) The Pulse Board considered the current operating environment,
  including, but not limited to, the continuing consolidation and increasing
  competition in the banking and financial services industries, the prospect
  for further changes in these industries, and the importance of being able
  to capitalize on developing opportunities in these industries. This
  information had been periodically reviewed by the Pulse Board at its
  regular board meetings and was also discussed between the Pulse Board and
  Pulse's various advisors.
 
    (d) The Pulse Board considered the other terms of the Merger Agreement
  and exhibits, including the tax-free nature of the transaction.
 
    (e) The Pulse Board considered the detailed financial analyses and other
  information with respect to First Source and Pulse discussed by Sandler
  O'Neill, as well as the Pulse Board's knowledge of Pulse, First Source and
  their respective businesses. In this regard, the latest publicly-available
  financial and other information for First Source and Pulse were analyzed,
  including a comparison to publicly-available financial and other
  information for other similar institutions.
     
    (f) The Pulse Board considered the value of Pulse Common Stock if Pulse
  continued as a stand-alone entity compared to the effect of Pulse combining
  with First Source in light of the factors summarized above and the current
  economic and financial environment, including, but not limited to, other
  possible strategic alternatives, the results of the contacts and
  discussions between Pulse and various third parties and the belief of the
  Pulse Board and management that the Merger offered the best transaction
  available to Pulse and its shareholders.     
 
    (g) The Pulse Board considered the likelihood of the Merger being
  approved by the appropriate regulatory authorities, including factors such
  as market share analysis, First Source's Community Reinvestment Act rating
  and the estimated pro forma financial impact of the Merger on First Source.
 
    (h) The Pulse Board considered the effect of the Merger on Pulse's
  employees, customers and the communities it serves.
 
  The foregoing discussion of the information and factors considered by
Pulse's Board is not intended to be exhaustive, but constitutes the material
factors considered by Pulse's Board. In reaching its determination to approve
and recommend the Merger Agreement, although Pulse's Board did not assign any
relative or specific weights to the foregoing factors, individual directors
may have weighed factors differently. After deliberating with respect to the
Merger and the other transactions contemplated by the Merger Agreement,
considering, among other things, the matters discussed above and the opinion
of Sandler O'Neill referred to above, the Pulse Board approved and adopted the
Merger Agreement and the transactions contemplated thereby as being in the
best interests of Pulse and its shareholders.
 
  First Source. The First Source Board believes that the Merger is fair to,
and in the best interests of, First Source and its stockholders. Accordingly,
the First Source Board has unanimously approved the Merger Agreement and
recommends that First Source's stockholders vote FOR the approval and adoption
of the Merger Agreement and consummation of the transactions contemplated
thereby.
   
  In reaching its decision to approve the Merger Agreement, the First Source
Board consulted with its legal advisors regarding the legal terms of the
transaction and First Source Board's obligations in its consideration of the
proposed transaction, its financial advisors regarding the financial aspects
and fairness of the proposed transaction, as well as with management of First
Source, and, without assigning any relative or specific weights, considered a
number of factors, both from a short-term and a longer-term perspective,
including the following:     
     
    (i) First Source Board's familiarity with and review of First Source's
  business, operations, financial condition, earnings and prospects,
  including, but not limited to, its potential growth, development,
  productivity and profitability and the business risks associated therewith;
      
                                      32
<PAGE>
 
     
    (ii) First Source Board's review, based in part on a presentation by
  First Source management regarding its due diligence on Pulse, of the
  business, operations, earnings and financial condition of Pulse on an
  historical, prospective and pro forma basis, and the enhanced opportunities
  for growth that the Merger makes possible;     
 
    (iii) a variety of factors affecting and relating to the overall
  strategic focus of First Source including, without limitation,
  opportunities for growth in deposits, assets and earnings, and
  opportunities available to First Source in the market areas where Pulse
  conducts business;
 
    (iv) the current and prospective economic, competitive and regulatory
  environment facing financial institutions, including First Source;
 
    (v) the terms of the Merger Agreement, the Stock Option Agreement and the
  other documents executed in connection with the Merger;
     
    (vi) the anticipated revenue enhancements, cost savings and efficiencies
  available from the Merger; and     
 
    (vii) the financial advice rendered by Ryan, Beck and the opinion of
  Ryan, Beck as to the fairness to First Source's stockholders from a
  financial point of view of the aggregate consideration to be paid by First
  Source in the Merger.
 
OPINIONS OF FINANCIAL ADVISORS
   
  Pulse. Pursuant to an engagement letter dated as of July 1, 1998 (the
"Sandler O'Neill Agreement"), Pulse retained Sandler O'Neill as an independent
financial advisor to render an opinion as to the fairness, from a financial
point of view, of the Exchange Ratio to the holders of Pulse Common Stock.
Sandler O'Neill is a nationally recognized investment banking firm whose
principal business specialty is financial institutions. In the ordinary course
of its investment banking business, Sandler O'Neill is regularly engaged in
the valuation of such businesses and their securities in connection with
mergers and acquisitions and other corporate transactions.     
   
  On July 9, 1998, Sandler O'Neill delivered to the Pulse Board its oral and
written opinion, that, as of such date, the Exchange Ratio was fair to the
holders of shares of Pulse Common Stock, from a financial point of view.
Sandler O'Neill has also delivered to the Pulse Board a written opinion dated
the date of this Joint Proxy Statement/Prospectus (the "Sandler O'Neill
Fairness Opinion") which is substantially identical to the July 9, 1998
opinion. THE FULL TEXT OF THE SANDLER O'NEILL FAIRNESS OPINION, WHICH SETS
FORTH THE PROCEDURES FOLLOWED, ASSUMPTIONS MADE, MATTERS CONSIDERED AND
QUALIFICATIONS AND LIMITATIONS ON THE REVIEW UNDERTAKEN IN CONNECTION WITH
SUCH OPINION, IS ATTACHED AS ANNEX C TO THIS JOINT PROXY STATEMENT/PROSPECTUS
AND IS INCORPORATED HEREIN BY REFERENCE. THE DESCRIPTION OF THE OPINION SET
FORTH HEREIN IS QUALIFIED IN ITS ENTIRETY BY REFERENCE TO ANNEX C. HOLDERS OF
SHARES OF PULSE COMMON STOCK ARE URGED TO READ THE SANDLER O'NEILL FAIRNESS
OPINION IN ITS ENTIRETY IN CONNECTION WITH THEIR CONSIDERATION OF THE PROPOSED
MERGER.     
 
  THE SANDLER O'NEILL FAIRNESS OPINION WAS PROVIDED TO THE PULSE BOARD FOR ITS
INFORMATION AND IS DIRECTED ONLY TO THE FAIRNESS, FROM A FINANCIAL POINT OF
VIEW, OF THE EXCHANGE RATIO TO HOLDERS OF SHARES OF PULSE COMMON STOCK. IT
DOES NOT ADDRESS THE UNDERLYING BUSINESS DECISION OF PULSE TO ENGAGE IN THE
MERGER OR ANY OTHER ASPECT OF THE MERGER AND DOES NOT CONSTITUTE A
RECOMMENDATION TO ANY HOLDER OF SHARES OF PULSE COMMON STOCK AS TO HOW SUCH
STOCKHOLDER SHOULD VOTE AT THE PULSE MEETING WITH RESPECT TO THE MERGER OR ANY
OTHER MATTER RELATED THERETO.
 
  In connection with rendering its July 9, 1998 opinion, Sandler O'Neill
performed a variety of financial analyses. The following is a summary of the
material analyses performed by Sandler O'Neill, but does not purport to be a
complete description of all the analyses underlying Sandler O'Neill's opinion.
The preparation of a fairness opinion is a complex process involving
subjective judgments and is not necessarily susceptible to a partial analysis
or summary description. Sandler O'Neill believes that its analyses must be
considered as a whole and that selecting portions of such analyses and the
factors considered therein, without considering all factors
 
                                      33
<PAGE>
 
and analyses, could create an incomplete view of the analyses and processes
underlying its opinion. In performing its analyses, Sandler O'Neill made
numerous assumptions with respect to industry performance, business and
economic conditions and various other matters, many of which cannot be
predicted and are beyond the control of Pulse, First Source and Sandler
O'Neill. Any estimates contained in Sandler O'Neill's analyses are not
necessarily indicative of future results or values, which may be significantly
more or less favorable than such estimates. Estimates on the values of
companies do not purport to be appraisals or necessarily reflect the prices at
which companies or their securities may actually be sold. Because such
estimates are inherently subject to uncertainty, neither Pulse nor Sandler
O'Neill assumes responsibility for their accuracy.
   
  Summary of Proposal. Sandler O'Neill reviewed the financial terms of the
proposed transaction. Based on the closing price of First Source Common Stock
on July 8, 1998 of $9.88 and an Exchange Ratio of 3.241, Sandler O'Neill
calculated an implied transaction value per share of Pulse of $32.00. Based
upon such implied transaction value and Pulse's March 31, 1998 financial
information, Sandler O'Neill calculated the price to tangible book value and
price to last twelve months' normalized earnings. This analysis yielded a
price to tangible book value multiple of 2.21x and a price to last twelve
months' earnings multiple of 18.2x.     
   
  Stock Trading History. Sandler O'Neill reviewed the history of the reported
trading prices and volume of Pulse Common Stock and the First Source Common
Stock, and the relationship between the movements in the prices of Pulse
Common Stock and the First Source Common Stock, respectively, to movements in
certain stock indices, including the Standard & Poor's 500 Index (the "S&P
Index"), the NASDAQ Bank Index (the "Bank Index") and selected composite
groups of publicly traded savings institutions (in the case of Pulse) and
larger publicly traded savings institutions (in the case of First Source),
identified below. During the one-year period ended July 8, 1998, Pulse Common
Stock outperformed the S&P Index and the Bank Index, and slightly
underperformed the peer group index. During the six-year period ended July 8,
1998, First Source Common Stock outperformed each of the indices to which it
was compared. During the three-month period since First Source's public
offering, ended July 8, 1998, First Source Common Stock underperformed each of
the indices to which it was compared.     
 
  Comparable Company Analysis. Sandler O'Neill used publicly available
information to compare selected financial and market trading information,
including balance sheet composition, asset quality ratios, loan loss reserve
levels, profitability, capital adequacy, dividends and trading multiples, for
Pulse and two groups of savings institutions. The first group consisted of
Pulse and the following twelve publicly traded regional savings institutions
(the "Regional Group"): Ambanc Holding Co., Bayonne Bancshares Inc., Carver
Bancorp Inc., Fidelity Bancorp Inc., First Bell Bancorp Inc., FMS Financial
Corp., Lakeview Financial Corp., Northeast PA Financial Corp., Progress
Financial Corp., Raritan Bancorp Inc., TF Financial Corp., and Statewide
Financial Corp. Sandler O'Neill also compared Pulse to a group of ten publicly
traded savings institutions which had a return on average equity (based on
last twelve months' earnings) of greater than 14.3% and a price to tangible
book value of greater than 218% (the "Highly Valued Group"). The Highly Valued
Group included the following institutions: American Bank of Connecticut,
Coastal Financial Corp., FMS Financial Corp., Highland Bancorp Inc., Home
Federal Bancorp, Lakeview Financial Corp., MetroWest Bank, First Mutual
Savings Bank, Progress Financial Corp., and PVF Capital Corp. The analysis
compared publicly available financial information for Pulse and the median
data for each of the Regional Group and the Highly Valued Group as of and for
each of the years ended December 31, 1993 through December 31, 1997 and as of
and for the twelve months ended March 31, 1998.
   
  Sandler O'Neill also used publicly available information to perform a
similar comparison of selected financial and market trading information for
First Source and two different groups of savings institutions. The first group
consisted of First Source and the following twelve publicly traded savings
institutions (the "Peer Group"): Dime Community Bancshares Inc., ESB Financial
Corp., Flushing Financial Corp., GA Financial Inc., JSB Financial Inc., Ocean
Financial Corp., Parkvale Financial Corp., PennFed Financial Services Inc.,
Peoples Bancorp Inc., Richmond County Financial Corp., WSFS Financial Corp.,
and York Financial Corp. Sandler O'Neill also compared First Source to a group
of fourteen publicly traded savings institutions which had a return on average
equity (based on last twelve months' earnings) of greater than 15.5% and a
price to tangible book     
 
                                      34
<PAGE>
 
value of greater than 169% (the "Larger Highly Valued Group"). The Larger
Highly Valued Group included American Bank of Connecticut, Anchor BanCorp
Wisconsin, CFSB Bancorp Inc., Coastal Financial Corp., D&N Financial Corp.,
First Federal Capital Corp., Highland Bancorp Inc., Home Federal Bancorp,
Lakeview Financial Corp., MECH Financial Inc., Metropolitan Financial Corp.,
MetroWest Bank, People's Bancshares Inc., and WSFS Financial Corp. The
analysis compared publicly available financial information for First Source
and the median data for each of the Peer Group and the Larger Highly Valued
Group as of and for each of the years ended December 31, 1993 through December
31, 1997 and as of and for the twelve months ended March 31, 1998.
   
  Analysis of Selected Merger Transactions. Sandler O'Neill reviewed 72
transactions announced from January 1, 1998 through July 8, 1998 involving
publicly traded savings institutions nationwide as acquired institutions with
transaction values greater than $15 million ("Nationwide Transactions") and 17
transactions announced from January 1, 1998 through July 8, 1998 involving
publicly traded savings institutions in the Mid-Atlantic Region (Maryland, New
Jersey, New York, and Pennsylvania) as acquired institutions with transaction
values greater than $15 million ("Regional Transactions"). Sandler O'Neill
reviewed the ratios of transaction value to last four quarters' earnings,
transaction value to book value, transaction value to tangible book value,
tangible book premium to core deposits, transaction value to total deposits
and transaction value to total assets and computed high, low, mean, and median
ratios and premiums for the respective groups of transactions. These multiples
were applied to Pulse's financial information as of and for the twelve months
ended March 31, 1998. Based upon the median multiples for Nationwide
Transactions, Sandler O'Neill derived an imputed range of values per share of
Pulse Common Stock of $29.68 to $41.02. Based upon the median multiples for
Regional Transactions, Sandler O'Neill derived an imputed range of values per
share of Pulse Common Stock of $28.97 to $44.97.     
 
  No company involved in the transactions included in the above analysis is
identical to Pulse and no transaction included in the above analysis is
identical to the Merger. Accordingly, an analysis of the results of the
foregoing analysis is not mathematical; rather, it involves complex
considerations and judgments concerning differences in financial and operating
characteristics of the companies and other factors that could affect the
public trading value of Pulse and First Source and the companies to which they
are being compared.
   
  Discounted Dividend Stream and Terminal Value Analysis. Sandler O'Neill also
performed an analysis which estimated the future stream of after-tax dividend
flows of Pulse through the year 2003 under various circumstances, assuming
Pulse performed in accordance with earnings forecasts of its management and
certain variations thereof. To approximate the terminal value of Pulse Common
Stock at December 31, 2003, Sandler O'Neill applied price to earnings
multiples ranging from 12x to 27x and applied multiples of tangible book value
ranging from 100% to 350%. The dividend income streams and terminal values
were then discounted to present values using different discount rates (ranging
from 9% to 15%) chosen to reflect different assumptions regarding required
rates of return of holders or prospective buyers of Pulse Common Stock. This
analysis, assuming the current dividend payout ratio and management's earnings
forecasts, indicated an imputed range of values per share of Pulse Common
Stock of $14.65 to $39.65 when applying the price to earnings multiples, and
an imputed range of values per share of Pulse Common Stock of $12.06 to $47.07
when applying multiples of tangible book value. In connection with its
analysis, Sandler O'Neill used sensitivity analyses to consider the effects
that changes in the underlying assumptions (including variations with respect
to the growth rate of assets, net interest spread, non-interest income, non-
interest expense and dividend payout ratio) would have on the resulting
present value and discussed these effects with the Pulse Board. Sandler
O'Neill noted that the discounted dividend stream and terminal value analysis
is a widely used valuation methodology, but the results of such methodology
are highly dependent upon the numerous assumptions that must be made, and the
results thereof are not necessarily indicative of actual values or actual
future results.     
   
  Pro Forma Merger Analysis. Sandler O'Neill analyzed certain potential pro
forma effects of the Merger through December 31, 2003, based upon an Exchange
Ratio of 3.241, Pulse's and First Source's current and projected income
statements and balance sheets, and assumptions regarding the economic
environment, accounting and tax treatment of the Merger, charges associated
with the Merger, operating efficiencies and other adjustments discussed with
senior managements of Pulse and First Source. This analysis indicated that the
Merger would be accretive to First Source's earnings per share for all periods
analyzed and dilutive to tangible     
 
                                      35
<PAGE>
 
   
book value per share of First Source's Common Stock for all periods analyzed.
This analysis also indicated that, from a Pulse shareholder's perspective, as
compared to the projected stand-alone performance of Pulse, the Merger would
be dilutive to Pulse's earnings per share and accretive to tangible book value
per share for all periods analyzed. The actual results achieved by the
combined company may vary from projected results and the variations may be
material.     
   
  In connection with rendering its July 9, 1998 opinion, Sandler O'Neill
reviewed, among other things: (i) the Merger Agreement and exhibits thereto;
(ii) the Stock Option Agreement; (iii) certain publicly available financial
statements of Pulse and other historical financial information provided by
Pulse that Sandler O'Neill deemed relevant; (iv) certain publicly available
financial statements of First Source and other historical financial
information provided by First Source that Sandler O'Neill deemed relevant; (v)
certain financial analyses and forecasts of Pulse prepared by and reviewed
with management of Pulse and the views of senior management of Pulse regarding
Pulse's past and current business, operations, results thereof, financial
condition and future prospects; (vi) certain financial analyses and forecasts
of First Source prepared by and reviewed with management of First Source and
the views of senior management of First Source regarding First Source's past
and current business, operations, results thereof, financial condition and
future prospects; (vii) the pro forma impact of the Merger; (viii) the
publicly reported historical price and trading activity for Pulse Common Stock
and First Source Common Stock, including a comparison of certain financial and
stock market information for Pulse and First Source with similar publicly
available information for certain other companies the securities of which are
publicly traded; (ix) the financial terms of recent business combinations in
the savings institution industry, to the extent publicly available; (x) the
current market environment generally and the banking environment in
particular; and (xi) such other information, financial studies, analyses and
investigations and financial, economic and market criteria as Sandler O'Neill
considered relevant. Sandler O'Neill did not act as Pulse's financial advisor
in connection with its consideration of the Merger or in connection with the
negotiation of the Merger Agreement, and Sandler O'Neill was not asked to, and
did not, solicit indications of interest in a potential transaction from third
parties.     
 
  In connection with rendering the Sandler O'Neill Fairness Opinion, Sandler
O'Neill confirmed the appropriateness of its reliance on the analyses used to
render its July 9, 1998 opinion by performing procedures to update certain of
such analyses and by reviewing the assumptions upon which such analyses were
based and the factors considered in connection therewith.
 
  In performing its reviews and analyses, Sandler O'Neill assumed and relied
upon, without independent verification, the accuracy and completeness of all
the financial information, analyses and other information that was publicly
available or otherwise furnished to, reviewed by or discussed with it, and
Sandler O'Neill does not assume any responsibility or liability therefor.
Sandler O'Neill did not make an independent evaluation or appraisal of the
specific assets, the collateral securing assets or the liabilities (contingent
or otherwise) of Pulse or First Source or any of their respective
subsidiaries, or the collectibility of any such assets, nor was it furnished
with any such evaluations or appraisals. Sandler O'Neill is not an expert in
the evaluation of allowances for loan losses and it has not made an
independent evaluation of the adequacy of the allowance for loan losses of
Pulse or First Source, nor has it reviewed any individual credit files
relating to Pulse or First Source. With Pulse's consent, Sandler O'Neill has
assumed that the respective aggregate allowances for loan losses for both
Pulse and First Source are adequate to cover such losses and will be adequate
on a pro forma basis for the combined entity. In addition, Sandler O'Neill has
not conducted any physical inspection of the properties or facilities of Pulse
or First Source. With respect to all financial information and projections
reviewed with each company's management, Sandler O'Neill assumed that they
have been reasonably prepared on bases reflecting the best currently available
estimates and judgments of the respective managements of the respective future
financial performances of Pulse and First Source and that such performances
will be achieved. Sandler O'Neill expressed no opinion as to such financial
projections or the assumptions on which they were based.
 
  Sandler O'Neill's opinion was necessarily based upon market, economic and
other conditions as they existed on, and could be evaluated as of, the date of
such opinion. Sandler O'Neill assumed, in all respects material to its
analysis, that all of the representations and warranties contained in the
Merger Agreement and all
 
                                      36
<PAGE>
 
related agreements are true and correct, that each party to such agreements
will perform all of the covenants required to be performed by such party under
such agreements and that the conditions precedent in the Merger Agreement are
not waived. Sandler O'Neill also assumed, with Pulse's consent, that there has
been no material change in Pulse's or First Source's assets, financial
condition, results of operations, business or prospects since the date of the
last publicly filed financial statements available to them, that Pulse and
First Source will remain as going concerns for all periods relevant to its
analyses, and that the Merger will be accounted for as a pooling of interests
and will qualify as a tax-free reorganization for federal income tax purposes.
 
  Under the Sandler O'Neill Agreement, Sandler O'Neill has received a fee of
$200,000 for rendering its fairness opinion. Pulse has also agreed to
reimburse Sandler O'Neill for its reasonable out-of-pocket expenses incurred
in connection with its engagement and to indemnify Sandler O'Neill and its
affiliates and their respective partners, directors, officers, employees,
agents, and controlling persons against certain expenses and liabilities,
including liabilities under securities laws.
   
  Sandler O'Neill has in the past provided certain other investment banking
services to Pulse and has received compensation for such services. Sandler
O'Neill has in the past provided certain investment banking services to First
Source and currently provides general advisory services to First Source and
has received compensation for such services. In addition, Sandler O'Neill may
in the future provide certain other investment banking services for First
Source and will receive compensation for such services. In the ordinary course
of its business as a broker/dealer, Sandler O'Neill may buy securities from
and sell securities to both Pulse and First Source. In addition, Sandler
O'Neill may actively trade the equity securities of Pulse and First Source and
their respective affiliates for its own account and for the accounts of
customers and, accordingly, may at any time hold a long or short position in
such securities.     
   
  First Source. Ryan, Beck began working with First Source during early June,
1998, and on July 8, 1998, First Source formally retained Ryan, Beck to advise
First Source on the acquisition of Pulse. Ryan, Beck is regularly engaged in
the valuation of banks, bank holding companies, savings and loan associations
and savings and loan holding companies in connection with mergers,
acquisitions and other securities-related transactions. Ryan, Beck has
knowledge of, and experience with, the New Jersey banking market and banking
organizations operating in that market, and was selected by First Source
because of its knowledge of, experience with, and reputation in the financial
services industry.     
   
  In its capacity as First Source's financial advisor, Ryan, Beck participated
in the negotiations with respect to the pricing and other terms and conditions
of the Merger, but the decision as to whether to acquire Pulse and the final
pricing of the Merger was ultimately made by the Board of Directors of First
Source on July 9, 1998. Ryan, Beck rendered its oral opinion to the First
Source Board on July 9, 1998, subsequently confirmed by a formal written
opinion dated as of the same date, and rendered an additional written opinion
dated November 3, 1998 (the "Opinion") that based on and subject to the
assumptions, factors and limitations as set forth in the Opinion and as
described below, that the Exchange Ratio is "fair" to First Source's
shareholders from a financial point of view. No limitations were imposed by
the First Source Board of Directors upon Ryan, Beck with respect to the
investigations made or procedures followed by it in arriving at its opinion.
       
  THE FULL TEXT OF THE RYAN, BECK OPINION DATED AS OF NOVEMBER 3, 1998, WHICH
SETS FORTH ASSUMPTIONS MADE AND MATTERS CONSIDERED, IS SUBSTANTIALLY THE SAME
AS THE OPINION RENDERED BY RYAN, BECK ON JULY 9, 1998, AND IS ATTACHED AS
ANNEX D TO THIS JOINT PROXY STATEMENT / PROSPECTUS. SHAREHOLDERS OF FIRST
SOURCE ARE URGED TO READ THE OPINION IN ITS ENTIRETY. RYAN, BECK'S OPINION IS
DIRECTED ONLY TO THE EXCHANGE RATIO AND DOES NOT CONSTITUTE A RECOMMENDATION
TO ANY FIRST SOURCE SHAREHOLDER AS TO HOW SUCH SHAREHOLDER SHOULD VOTE AT THE
SPECIAL MEETING. THE SUMMARY OF THE OPINION OF RYAN, BECK SET FORTH IN THIS
JOINT PROXY STATEMENT / PROSPECTUS IS QUALIFIED IN ITS ENTIRETY BY REFERENCE
TO THE FULL TEXT OF SUCH OPINION. RYAN, BECK DOES NOT ADMIT THAT IT IS AN
EXPERT WITHIN THE MEANING OF THE TERM "EXPERT" AS USED IN THE SECURITIES ACT
AND THE RULES AND REGULATIONS PROMULGATED THEREUNDER, OR THAT ITS OPINIONS
CONSTITUTE A REPORT OR VALUATION WITHIN THE MEANING OF SECTION 11 OF THE ACT
AND THE RULES AND REGULATIONS PROMULGATED THEREUNDER.

  In connection with its analysis, Ryan, Beck: (i) reviewed the Merger
Agreement and related documents; (ii) reviewed this Joint Proxy
Statement/Prospectus; (iii) reviewed First Source's Annual Reports to
Shareholders and Annual Reports on Form 10-K for the years ended December 31,
1997, 1996, and 1995, and First Source's Quarterly Reports on Form 10-Q for
the periods ended June 30, 1998, March 31, 1998, September 30, 1997, June 30,
1997 and March 31, 1997; (iv) reviewed First Source's Registration Statement
filed on Form S-1/A dated February 9, 1998 in connection with its conversion
from a mutual holding company structure to a stock holding company structure;
(v) reviewed Pulse's Annual Reports to Shareholders and Annual Reports on Form
10-K for the years ended September 30, 1997, 1996, and 1995, and Pulse's
Quarterly Reports on Form 10-Q for the periods ended June 30, 1998, March 31,
1998, December 31, 1997, June 30, 1997 and March 31, 1997; (vi) reviewed the
historical stock prices and trading volume of First Source Common Stock; (vii)
reviewed the historical stock prices and trading volume of Pulse Common Stock;
(viii) reviewed the publicly available financial data of thrift organizations
which Ryan, Beck deemed generally comparable to First Source; (ix) reviewed
the publicly available financial data of thrift organizations which Ryan, Beck
deemed generally comparable to Pulse; (x) reviewed the terms of recent
acquisitions of thrift organizations which Ryan, Beck deemed generally
comparable in whole or in part to Pulse; and (xi) reviewed the potential pro
forma impact of the Merger on First Source's financial condition, operating
results and per share figures. Ryan, Beck also conducted or reviewed such
other studies, analyses, inquiries and examinations as deemed appropriate.
Ryan, Beck also reviewed certain financial projections provided by First
Source and Pulse for the year ending December 31, 1998 and met with certain
members of First Source and Pulse's senior management to discuss First Source
and Pulse's past and current business operations, financial condition,
strategic plan and future prospects, including the prospects for the combined
company and any potential operating efficiencies and synergies which may arise
from the Merger.     
 
  In connection with its review, Ryan, Beck relied upon and assumed, without
independent verification, the accuracy and completeness of the financial and
other information regarding First Source and Pulse provided to Ryan, Beck by
First Source and Pulse and their representatives. Ryan, Beck is not an expert
in the evaluation of allowances for loan losses. Therefore, Ryan, Beck has not
assumed any responsibility for making an independent evaluation of the
adequacy of the allowances for loan losses as set forth on First Source and
Pulse's balance sheets at June 30, 1998, and Ryan, Beck assumed such
allowances were adequate and complied fully with applicable law, regulatory
policy and prudent banking practice as of the date of such financial
statements. Ryan, Beck has reviewed certain historical financial data and
financial projections (and the assumptions and bases therefor) provided by
First Source and Pulse. Ryan, Beck assumed that such forecasts and projections
reflected the best currently available estimates and judgments of the
respective managements. In certain instances, for the purposes of its
analyses, Ryan, Beck made adjustments to such financial and operating
forecasts which in Ryan, Beck's judgment were appropriate under the
circumstances. Ryan, Beck was not retained to nor did it make any independent
evaluation or appraisal of the assets or liabilities of First Source or Pulse
nor did Ryan, Beck review any loan files of First Source or Pulse or their
respective subsidiaries. Ryan, Beck also assumed that the Merger in all
respects is, and will be, undertaken and consummated in compliance with all
laws and regulations that are applicable to First Source and Pulse.
 
  The preparation of a fairness opinion on a transaction such as the Merger
involves various determinations as to the most appropriate and relevant
methods of financial analysis and the application of those methods to the
particular circumstances and, therefore, the Opinion is not readily
susceptible to summary description. In arriving at its opinion, Ryan, Beck
performed a variety of financial analyses. Ryan, Beck believes that its
analyses must be considered as a whole and the consideration of portions of
such analyses and the factors considered therein, without considering all
factors and analyses, could create an incomplete view of the analyses and the
process underlying Ryan, Beck's Opinion. No one of the analyses was assigned a
greater significance than any other.
 
  The projections furnished to Ryan, Beck were prepared by the respective
managements of First Source and Pulse, without input or guidance by Ryan,
Beck. First Source and Pulse do not publicly disclose internal management
projections of the type provided to Ryan, Beck in connection with the review
of the Merger. Such projections were not prepared with a view towards public
disclosure. The public disclosure of such projections
 
                                      38
<PAGE>
 
could be misleading since the projections were based on numerous variables and
assumptions which are inherently uncertain, including, without limitation,
factors related to general economic and competitive conditions. Accordingly,
actual results could vary significantly from those set forth in such
projections.
 
  In its analyses, Ryan, Beck made numerous assumptions with respect to
industry performance, business and economic conditions, and other matters,
many of which are beyond the control of First Source or Pulse. Any estimates
contained in Ryan, Beck's analyses are not necessarily indicative of future
results or values, which may be significantly more or less favorable than such
estimates. Estimates of values of companies do not purport to be appraisals
nor do they necessarily reflect the prices at which companies or their
securities may actually be sold.
 
  The following is a brief summary of the analyses and procedures performed by
Ryan, Beck in the course of arriving at its opinion.
   
  Analysis of Selected Publicly Traded Companies: Ryan, Beck compared Pulse's
financial data as of March 31, 1998 to a peer group of fifteen thrift
organizations located in the Mid-Atlantic region with assets between $400
million and $1.1 billion. Ryan, Beck deemed this group to be generally
comparable to Pulse. At or for the twelve months ended March 31, 1998, Pulse
had tangible equity to tangible assets of 8.34%, a return on average assets of
1.07%, a return on average equity of 13.17%, a net interest margin of 2.67%, a
ratio of non-interest expenses to average assets of 1.04%, a ratio of non-
performing loans (including loans 90 days past due and still accruing
interest) to total loans of 0.85%, a ratio of non-performing assets (including
loans 90 days past due and still accruing interest) to total assets of 0.60%,
a ratio of loan loss reserves to non-performing loans (including loans 90 days
past due and still accruing interest) of 170.00%, an efficiency ratio of
38.65%, total loans to total assets of 26.35%, and non-interest income to
average assets of 0.08%. These ratios were compared to the median ratios of
the fifteen selected thrift organizations, which were, as calculated, a
tangible equity to tangible assets ratio of 7.78%, a return on average assets
of 0.85%, a return on average equity of 8.69%, a net interest margin of 3.26%,
a ratio of non-interest expenses to average assets of 2.15%, a ratio of non-
performing loans (including loans 90 days past due and still accruing
interest) to total loans of 0.65%, a ratio of non-performing assets (including
loans 90 days past due and still accruing interest) to total assets of 0.47%,
a ratio of loan loss reserves to non-performing loans (including loans 90 days
past due and still accruing interest) of 125.97%, an efficiency ratio of
58.28%, total loans to total assets of 49.75%, and non-interest income to
average assets of 0.27%. Ryan, Beck noted that the performance of Pulse as
measured by a return on average assets and average equity ratio was superior
to that of the peer group. Additionally, Ryan, Beck noted that Pulse's low
level of non-interest expenses as a percent of average assets more than
compensates for their lower net interest margin and non-interest income as a
percent of average assets when compared to the peer group. This is evidenced
by their superior efficiency ratio. Ryan, Beck also noted the significantly
lower level of loans at Pulse relative to its peers.     
 
  Ryan, Beck also compared First Source's financial data as of May 31, 1998
(pro forma for their "second step" conversion from mutual holding company
structure to stock holding company structure) with that of a group of nineteen
selected thrift organizations located in the Mid-Atlantic region with assets
between $500 million and $2.0 billion. Ryan, Beck deemed this group to be
generally comparable to First Source. At or for the twelve months ended May
31, 1998, First Source had tangible equity to tangible assets of 20.87%, a
return on average assets of 1.18%, a return on average equity of 5.50%, a
dividend yield of 1.19%, a net interest margin of 2.98%, an efficiency ratio
of 42.05%, a ratio of non-performing loans (including loans 90 days past due
and still accruing interest) to total loans of 0.51%, a ratio of non-
performing assets (including loans 90 days past due and still accruing
interest) to total assets of 0.38% and a ratio of reserves to non-performing
loans (including loans 90 days past due and still accruing interest) of
208.36%. These ratios were compared to the median ratios of the nineteen
selected thrift organizations, which were, as calculated, a tangible equity to
tangible assets ratio of 9.82%, a return on average assets ratio of 0.92%, a
return on average equity ratio of 10.15%, a dividend yield of 1.84%, a net
interest margin of 3.26%, an efficiency ratio of 51.31%, a ratio of non-
performing loans (including loans 90 days past due and still accruing
interest) to total loans of 0.85%, a ratio of non-performing assets (including
loans 90 days past due and still accruing interest) to total assets of 0.51%
and a ratio of reserves to non-performing loans (including loans 90 days past
due and still accruing interest) of
 
                                      39

125.97%. Using First Source's July 6, 1998 Common Stock price of $10.06, its
price to Last Twelve Months ("LTM") earnings was 23.4 times, price to book
value was 123.77% and price to tangible book value was 127.86%. The peer
group's median price to LTM earnings was 17.0 times, price to book value was
166.04% and price to tangible book value was 173.42%. Financial data for the
peer group was generally as of March 31, 1998.     
 
  Analysis of Selected Transactions: Ryan, Beck compared Pulse's financial
data at or for the twelve months ended March 31, 1998 with that of a group of
eight selected thrift organizations being acquired in transactions accounted
for as pooling-of-interests, announced since June 1, 1997, and for which
pricing data pertaining to the transactions was publicly available. The
criteria for this group was thrifts in the New England and Mid-Atlantic
regions with assets between $350 million and $750 million and equity to assets
less than 15%. Ryan, Beck deemed this group to be generally comparable to
Pulse. The median ratios of the eight selected companies, as calculated,
represented a 7.88% tangible equity to tangible assets ratio, a non-performing
assets to assets ratio of 0.78%, an annualized year-to-date return on average
assets of 0.96% and an annualized year-to-date return on average equity of
11.34%. These ratios were compared to Pulse's ratios, which were, as
calculated, a 8.34% tangible equity to tangible assets ratio, a non-performing
assets to assets ratio of 0.60%, a return on average assets of 1.07%, and a
return on average equity of 13.17%.
   
  Ryan, Beck also calculated certain ratios based on the $32.00, subject to
adjustments and limitations, of First Source Common Stock to be issued for
each share of Pulse. This price represented 221.15% of book value at March 31,
1998, 221.15% of tangible book value at March 31, 1998, 18.18 times LTM
diluted earnings, and a core deposit premium to tangible book value at March
31, 1998 of 12.73%. The median ratios for the Comparable Transactions, as
calculated, represented a price to book value of 237.14%, a price to tangible
book value of 238.93%, a price to latest twelve months diluted earnings of
21.02 times and a core deposit premium to tangible book value of 17.35%. The
imputed value of Pulse based on the median multiples of the above mentioned
acquisition peer group was $34.31 based on price to book value, $34.57 based
on price to tangible book value, $37.00 based on price to LTM diluted earnings
and $38.35 based on the core deposit premium to tangible book value.     
   
  Prior to issuing the Opinion, Ryan, Beck updated its analyses and adjusted
the peer group statistics to reflect the change in the Nasdaq Bank Stock Index
from the date of announcement of each stock transaction to the closing value
of the index on October 28, 1998. The resultant median ratios for the
Comparable Transactions, as calculated, represented a price to stated book
value of 216.06%, a price to tangible book value of 221.99%, a price to latest
twelve months earnings of 21.02 times, and a core deposit premium over
tangible book value of 15.92%. The imputed value of Pulse based on the
adjusted median ratios of the above mentioned peer group was $32.45 based on
price to stated book value, $33.34 based on price to tangible book value,
$36.57 based on price to latest twelve months earnings, $36.15 based on the
core deposit premium to tangible book value.     
 
  No company or transaction used in the Analysis of Selected Publicly Traded
Companies and Transactions sections is identical to Pulse, First Source or the
Merger. Accordingly, an analysis of the results of the foregoing is not
mathematical; rather it involves complex considerations and judgments
concerning differences in financial and operating characteristics of the
companies involved and other factors that could affect the trading values of
the securities of the company or companies to which they are being compared.
   
  Impact Analysis: Ryan, Beck analyzed the Merger in terms of its effect on
First Source's projected earnings per share, current book value, tangible book
value, and capital ratios. Ryan, Beck based its analysis on First Source and
Pulse's projected 1999 earnings, as provided by the management of First Source
and Pulse, assumed to grow thereafter at a compound annual growth rate of 7%,
and certain assumptions with respect to cost savings and other synergies and
the amount of the restructuring charge resulting from the Merger. Based upon
the stand alone earnings projections provided by First Source and Pulse and
First Source's closing stock price on July 6, 1998 of $10.06 per share, the
analysis showed that the Merger would be accretive to First Source's estimated
1999 earnings per share by approximately 6.9% and accretive to 2000 earnings
per share by approximately 6.4%. Based upon First Source's and Pulse's May 31,
1998 and March 31, 1998 estimated financial data, respectively, the Merger
would be dilutive to First Source's book value per share by approximately     
 
                                      40
<PAGE>
 
   
11.1%, and dilutive to First Source's tangible book value per share by
approximately 10.6%. Based upon May 31, 1998 estimated financial data, First
Source's pro forma total equity to total assets would decrease from 21.76% to
17.60%, its tangible equity to tangible assets would decrease from 21.21% to
17.20%, and its intangible assets to total equity would be reduced from 3.21%
to 2.74%. Ryan, Beck updated its analysis prior to issuing the Opinion using
First Source's closing stock price as of October 28, 1998. The analysis showed
that the merger would be accretive to First Source's estimated 1999 earnings
per share by approximately 1.5% and accretive to 2000 earnings per share by
approximately 1.1%. Based upon First Source's and Pulse's September 30, 1998
financial data, respectively, the Merger would be dilutive to First Source's
book value per share by approximately 14.3%, and dilutive to First Source's
tangible book value per share by approximately 13.9%. First Source's pro forma
total equity to total assets would decrease from 20.88% to 17.14%, its
tangible equity to tangible assets would decrease from 20.36% to 16.76%, and
its intangible assets to total equity would be reduced from 3.10% to 2.66%.
The actual results achieved may vary from the projected results and the
variations may be material.     
 
  Discounted Dividend Analysis: Using a discounted dividend analysis, Ryan,
Beck estimated the present value of the future dividend streams that Pulse
could produce in perpetuity. Projection ranges for Pulse's five-year balance
sheet and income statement were provided by Pulse's management. Management's
projections were based upon various factors and assumptions, many of which are
beyond the control of Pulse. These projections are, by their nature, forward-
looking and may differ materially from the actual values or actual future
results which may be significantly more or less favorable than suggested by
such projections. In producing a range of per share Pulse values, Ryan, Beck
utilized the following assumptions: discount rates range from 11.0% to 13.0%,
terminal price/earnings multiples range from 14.0x to 16.0x (which when
applied to terminal year estimated earnings produces a value which
approximates the net present value of the dividends in perpetuity, given
certain assumptions regarding growth rates and discount rates) and earnings
that include estimated savings in Pulse's non-interest expenses equal to 41.8%
in 1999 and 2000 with an assumed 5% annual growth in synergies in years
thereafter. The discounted dividend analysis produced a range of net present
values per share of Pulse Common Stock from $28.43 to $33.46. These analyses
do not purport to be indicative of actual values or expected values or an
appraisal range of the shares of Pulse Common Stock. Ryan, Beck noted that the
discounted dividend analysis is a widely used valuation methodology, but noted
that it relies on numerous assumptions, including expense savings levels,
dividend payout rates, terminal values and discount rates, the future values
of which may be significantly more or less than such assumptions. Any
variation from these assumptions would most likely produce different results.
   
  In connection with its written Opinion dated as of November 3, 1998, Ryan,
Beck confirmed the appropriateness of its reliance on the analyses used to
render its July 9, 1998 oral and written opinions by performing procedures to
update certain of such analyses and by reviewing the assumptions and
conclusions contained in the July 9, 1998 opinion.     
   
  RYAN, BECK'S WRITTEN OPINION DATED NOVEMBER 3, 1998 WAS BASED SOLELY UPON
THE INFORMATION AVAILABLE TO IT AND THE ECONOMIC, MARKET AND OTHER
CIRCUMSTANCES AS THEY EXISTED AS OF THE DATE OF SUCH OPINION. RYAN, BECK DID
NOT EXPRESS ANY OPINION AS TO THE PRICE OR RANGE OF PRICES AT WHICH FIRST
SOURCE COMMON STOCK MIGHT TRADE SUBSEQUENT TO THE MERGER. EVENTS OCCURRING
AFTER SUCH DATE COULD MATERIALLY AFFECT THE ASSUMPTIONS AND CONCLUSIONS
CONTAINED IN SUCH OPINION. RYAN, BECK HAS NOT UNDERTAKEN TO REAFFIRM OR REVISE
ITS OPINION OR OTHERWISE COMMENT UPON ANY EVENTS OCCURRING AFTER THE DATE OF
THE OPINION.     
   
  The opinion of Ryan, Beck that the Exchange Ratio is fair to First Source's
shareholders from a financial point of view does not include situations in
which Pulse elects to terminate the Merger Agreement as a result of a decline
in the price of First Source Common Stock to $8.50 or less. Under such
circumstances, First Source can override such termination by increasing the
number of shares of First Source Common Stock issuable for each share of Pulse
Common Stock from 3.2 shares to such number of shares of First Source Common
Stock having an aggregate market value of $32.00 based upon the First Source
Market Value as of the determination date. Whether or not First Source would
agree to increase the Exchange Ratio would have to be evaluated by     
 
                                      41
<PAGE>
 
   
First Source's Board of Directors at the time of any such termination by Pulse
based upon the facts and circumstances existing at that time. In connection
with any such evaluation by First Source's Board of Directors, First Source
intends to request Ryan, Beck to reevaluate the transaction to determine
whether the revised Exchange Ratio is fair to First Source's shareholders from
a financial point of view. Ryan, Beck has been advised by First Source that it
would be requested to update its opinion under such circumstances and that, in
the event that Ryan, Beck is unable to deliver an opinion under such
circumstances and First Source nonetheless elects to override Pulse's
termination of the Merger Agreement and proceed with the Merger, First Source
would resolicit its shareholders to advise them of such facts.     
 
  The summary set forth above does not purport to be a complete description,
but is a brief summary of the material analyses and procedures performed by
Ryan, Beck in the course of arriving at its Opinion.
 
  With regard to Ryan, Beck's services in connection with the Merger
Agreement, First Source has agreed to pay Ryan, Beck an advisory fee of
approximately $800,000. A portion of Ryan, Beck's advisory fee equal to
approximately $200,000 was paid upon execution of the Merger Agreement and the
remainder will be paid at the time of the closing of the Merger. First Source
has also agreed to pay Ryan, Beck an additional $50,000 for issuing an opinion
at the completion of the Merger, should an additional opinion be requested. In
addition, First Source has agreed to reimburse Ryan, Beck for its reasonable
out-of-pocket expenses, which shall not exceed $5,000 without the prior
consent of First Source. First Source has also agreed to indemnify Ryan, Beck
and certain related persons against certain liabilities, including liabilities
under federal securities law, incurred in connection with its services. The
amounts of Ryan, Beck's fees were determined by negotiation between First
Source and Ryan, Beck.
 
  Ryan, Beck has had a prior investment banking relationship with First
Source. Ryan, Beck was the sole underwriter for First Source, which was then
known as First Savings Bank, in both its May, 1992 reorganization from a
mutual to a mutual holding company structure and its May, 1995 secondary stock
offering. Ryan, Beck was also a financial advisor, but not an underwriter for
First Source in its "second step" conversion dated April 9, 1998 from a mutual
holding company structure to a stock holding company structure. Additionally,
Ryan, Beck acted as financial advisor with respect to the sale of a branch
office. Additionally, Ryan, Beck's research department has issued research
reports on First Source and comments on First Source in its periodic
commentaries. Ryan, Beck is also a market maker in First Source's stock.
 
  Ryan, Beck has not had an investment banking relationship with Pulse since
1986. Ryan, Beck was the sole underwriter of Pulse's conversion, which was
then known as Pulawski Savings and Loan Association, from a mutual to a stock
savings and loan association in September, 1986. Ryan, Beck is a market maker
in Pulse's stock. Ryan, Beck's research department does not cover Pulse.

  Consulting Agreement. It is intended that upon the Effective Date of the
Merger, First Source will enter into a consulting agreement with George T.
Hornyak, Jr. The agreement with Mr. Hornyak will have a term of three years
during which time he will serve as consultant with an annual fee of $150,000.
During the term of the consulting agreement Mr. Hornyak will continue to
receive reimbursement for coverage for family medical insurance benefits;
existing supplemental life insurance covering Mr. Hornyak will be prepaid in
an amount up to $36,000 and country club dues and automobile benefits will
continue to be provided in an aggregate amount of up to $60,000.     
   
  Directorships. On or before the Effective Time, the First Source Board will
appoint George T. Hornyak, Jr. and Joseph Chadwick, directors of Pulse, to
newly-created directorships on the First Source Board for a term to expire in
the years 2001 and 1999, respectively. Messrs. Hornyak and Chadwick will also
be appointed to the board of directors of First Savings Bank for a term
expiring in 1999. Following their terms, they will be considered for re-
election to the boards of directors of First Source and First Savings Bank.
The Merger Agreement provides that Mr. Hornyak and Mr. Chadwick will
participate in the future stock benefit plans of First Source to the same
extent as other non-employee directors of First Source. See "APPROVAL OF THE
FIRST SOURCE BANCORP, INC. 1998 STOCK-BASED INCENTIVE PLAN." All other
directors of Pulse will serve on the Advisory Board of First Source for at
least three (3) years. Each advisory director will be entitled to an initial
payment of $45,000 during the first year of their term and $12,000 in each of
the first, second and third years of their term, or, instead, annuities of
comparable value. See "Management After the Merger."     
 
  Termination of Existing Employment Agreements. As of the Effective Time,
Pulse will terminate the employment of George T. Hornyak, Jr., Benjamin S.
Konopacki, and Thomas Konopacki, and make payments in accordance with their
employment agreements. As a result, the estimated amounts of payment at that
time is $958,000 for Mr. Hornyak, $165,000 for Mr. B. Konopacki, and $442,000
for Mr. T. Konopacki.
   
  Continued Retainer of General Counsel. Mr. Kolodziej, the general counsel to
Pulse, will continue with the current retainer agreement for a period of three
years after the Merger with a prepaid aggregate retainer of $39,000 for the
three year period.     
   
  Severance Benefits. First Source has agreed that in the event any Pulse Bank
employee loses his/her job within one year of the merger, the employee will be
entitled to two weeks pay per year of employment.     
 
  Indemnification of and Continued Insurance Coverage for Pulse
Management. First Source has agreed that for a period of six (6) years
following the closing date of the Merger, the Merger will not affect or
diminish any of Pulse's duties and obligations of indemnification existing as
of the closing date of the Merger in favor of employees, agents, directors or
officers of Pulse or any of its subsidiaries arising by virtue of Pulse's
Certificate of Incorporation or Bylaws in the form in effect at the date of
the Merger Agreement or arising by operation of law. First Source will cause
the persons serving as officers and directors of Pulse immediately prior to
the closing date of the Merger to be covered for a period of six (6) years
from the closing date of the Merger by the directors' and officers' liability
insurance policy maintained by Pulse (provided that First Source may
substitute therefor policies of at least the same coverage and amounts
containing terms and conditions which are not materially less advantageous
than such policy) with respect to acts or omissions occurring prior to the
closing date of the Merger which were committed by such officers and directors
in their capacity as such.
 
EMPLOYEE MATTERS
 
  Pursuant to the terms of the Merger Agreement, employees of Pulse shall
become entitled to participate in certain benefit plans maintained by First
Source on the same terms and conditions as applicable to comparable employees
of First Source and shall be granted credit for service with Pulse for certain
purposes under certain of such plans. Pursuant to the terms of the Merger
Agreement, First Source has agreed to honor in accordance with their terms,
certain employment, severance and other compensation agreements and
arrangements between Pulse and certain of its directors, officers and
employees.
 
 
                                      43

EFFECTIVE TIME
 
  The Merger will become effective upon the filing of a certificate of merger
with the Secretary of State of the State of Delaware in accordance with
applicable law or such later time as is specified in such certificate (the
"Effective Time"). The filing with respect to the Merger will occur on the
first day (the "Closing Date") which is (i) the last business day of a month
and (ii) at least two business days after satisfaction or waiver of the latest
to occur of certain conditions to the Merger specified in the Merger
Agreement, unless another date is agreed to in writing by First Source and
Pulse. See "--Conditions to the Merger" below. It is expected that a period of
time will elapse between the Special Meetings and the Effective Time while the
parties seek to obtain the regulatory approvals required to consummate the
Merger. There can be no assurance that such regulatory approvals will be
obtained, and if obtained, there can be no assurance as to the date of any
such approval. There can also be no assurance that any such approvals will not
contain a Burdensome Condition (as defined below) which causes such approvals
to fail to satisfy the conditions set forth in the Merger Agreement and
described below under "--Conditions to the Merger." There can likewise be no
assurance that the United States Department of Justice or the New Jersey
Attorney General will not challenge the Merger or, if such a challenge is
made, as to the result thereof. See "--Regulatory Approvals Required for the
Merger" below. The Merger Agreement may be terminated by either party if,
among other reasons, the Merger has not been consummated on or before March
31, 1999. See "--Waiver and Amendment; Termination" below.
 
CONVERSION OF SHARES; PROCEDURES FOR EXCHANGE OF CERTIFICATES; FRACTIONAL
SHARES
   
  Pulse. As promptly as practicable after the Effective Time, and in no event
more than three business days thereafter, a transfer agent selected by First
Source and reasonably satisfactory to Pulse, acting in the capacity of
exchange agent (the "Exchange Agent"), will mail to each former holder of
record of Pulse Common Stock a form of letter of transmittal, together with
instructions for the exchange of such holder's certificates representing
shares of Pulse Common Stock for certificates representing shares of First
Source Common Stock and cash in lieu of fractional shares.     
 
  HOLDERS OF PULSE COMMON STOCK SHOULD NOT SEND IN THEIR CERTIFICATES UNTIL
THEY RECEIVE THE LETTER OF TRANSMITTAL FORM AND INSTRUCTIONS FROM THE EXCHANGE
AGENT, AND SHOULD NOT RETURN SUCH STOCK CERTIFICATES WITH THE ENCLOSED PROXY.
   
  Upon surrender to the Exchange Agent of one or more certificates
representing shares of Pulse Common Stock, together with a properly completed
letter of transmittal, there will be issued and mailed to the holder of Pulse
Common Stock surrendering such items a certificate or certificates
representing the number of shares of First Source Common Stock to which such
holder is entitled and, where applicable, a check for the amount representing
any fractional share determined in the manner described below, without
interest. The Pulse certificate or certificates so surrendered will be
cancelled.     
 
  No dividend or other distribution declared after the Effective Time with
respect to First Source Common Stock will be paid to the holder of any
unsurrendered Pulse certificate until the holder surrenders such certificate,
at which time the holder will be entitled to receive all previously withheld
dividends and distributions, without interest. No holder of an unsurrendered
Pulse certificate will be entitled, until the surrender of such certificate,
to vote the shares of First Source Common Stock into which his or her shares
of Pulse Common Stock have been converted.
 
  After the Effective Time, there will be no transfers on the stock transfer
books of Pulse of shares of Pulse Common Stock issued and outstanding
immediately prior to the Effective Time. If certificates representing shares
of Pulse Common Stock are presented for transfer after the Effective Time,
they will be cancelled and exchanged for certificates representing shares of
First Source Common Stock.
 
 
                                      44
<PAGE>
 
  None of the Exchange Agent, First Source or Pulse, or any other person, will
be liable to any former holder of Pulse Common Stock for any amount properly
delivered to a public official pursuant to applicable abandoned property,
escheat or similar laws.
 
  If a certificate for Pulse Common Stock has been lost, stolen or destroyed,
the Exchange Agent will issue the consideration properly payable in accordance
with the Merger Agreement upon receipt of appropriate evidence as to such
loss, theft or destruction, appropriate evidence as to the ownership of such
certificate by the claimant, and appropriate and customary indemnification.
   
  No fractional shares of First Source Common Stock will be issued in the
Merger. Instead, the Merger Agreement provides that each holder of shares of
Pulse Common Stock exchanged pursuant to the Merger who would otherwise have
been entitled to receive a fraction of a share of First Source Common Stock
will receive, in lieu thereof, cash in an amount equal to such fractional part
of a share of First Source Common Stock multiplied by the Average Closing
Price of First Source Common Stock. See "THE MERGER--Exchange Ratio" for a
discussion of the Average Closing Price. No such holder will be entitled to
dividends, voting rights or any other rights as a stockholder in respect of
any fractional share to which such holder would otherwise have been entitled
to receive.     
 
  First Source. Shares of First Source Common Stock issued and outstanding
immediately prior to the Effective Time will remain issued and outstanding and
be unaffected by the Merger, and holders of such stock will not be required to
exchange the certificates representing such stock or take any other action by
reason of the consummation of the Merger.
 
CONDITIONS TO THE MERGER
 
  The respective obligations of First Source and Pulse to effect the Merger
are subject to the satisfaction of the following conditions at or prior to the
Effective Time: (i) approval of the Merger Agreement by the affirmative vote

Common Stock entitled to vote thereon and by the affirmative vote of the
holders of at least a majority of the outstanding shares of First Source
Common Stock entitled to vote thereon; (ii) the shares of First Source Common
Stock issuable to holders of Pulse Common Stock pursuant to the Merger shall
have been authorized for listing on the Nasdaq Stock Market, subject to
official notice of issuance; (iii) approval of the Merger Agreement and the
transactions contemplated thereby (including the Merger and the Subsidiary
Bank Merger by the appropriate governmental authorities (all such governmental

the "Requisite Regulatory Approvals") (see "--Regulatory Approvals Required
for the Merger" below); (iv) receipt of all necessary state securities laws
and "blue sky" permits and other authorizations required in connection with
the issuance of First Source Common Stock in the Merger; (v) the Registration
Statement of which this Joint Proxy Statement/Prospectus forms a part will

"Securities Act") and no stop order suspending the effectiveness of the

purpose will have been initiated or threatened by the Commission; (vi) no
order, injunction or decree issued by any court or agency of competent
jurisdiction or other legal restraint or prohibition (an "Injunction") which
prohibits the consummation of the Merger, the Subsidiary Bank Merger or any of
the other transactions contemplated by the Merger Agreement or the Subsidiary
Bank Merger Agreement (as defined below) will be in effect; (vii) no statute,
rule, regulation, order, injunction or decree will have been enacted, entered,
promulgated or enforced by any Governmental Entity which prohibits, restricts
or makes illegal consummation of the Merger or the Subsidiary Bank Merger and
(viii) the receipt of a letter from the accountants of First Source that the
merger will qualify as a "pooling of interests."
   
  The obligations of First Source to effect the Merger are further subject to
the satisfaction, or waiver by First Source, of the following conditions: (i)
the representations and warranties of Pulse contained in the Merger Agreement
shall be true and correct in all material respects as of the date of the
Merger Agreement and (except to the extent that such representations and

                                      45
<PAGE>
 
   
made at and as of the Effective Time, provided, that for purposes of
determining the satisfaction of the condition described in this clause (i),
the representations and warranties of Pulse will be deemed true and correct in
all material respects unless the failure or failures of such representations
and warranties to be so true and correct, in the aggregate, represent a
material adverse change from the business, assets, financial condition or
results of operations of Pulse and its subsidiaries taken as a whole as
represented in the Merger Agreement; (ii) Pulse shall have performed in all
material respects all obligations required to be performed by it under the
Merger Agreement at or prior to the Effective Time; (iii) none of the
Requisite Regulatory Approvals shall impose any term, condition or restriction
upon First Source, Pulse, First Savings Bank, SLA or Pulse Bank or any of
their respective subsidiaries that First Source or Pulse, in good faith,
reasonably determines would so materially adversely affect the economic or
business benefits of the transactions contemplated by the Merger Agreement to
First Source or Pulse as to render inadvisable the consummation of the Merger
("a Burdensome Condition"); (iv) the consent, approval or waiver of each
person (other than the Governmental Entities) whose consent or approval shall
be required in order to permit the succession by the surviving corporation in
the Merger or the surviving bank in the Subsidiary Bank Merger to any
obligation, right or interest of Pulse or any subsidiary of Pulse under any
agreement shall have been obtained, except where the failure to obtain such
consent, approval or waiver would not so materially adversely affect the
economic or business benefits of the transactions contemplated by the Merger
Agreement to First Source as to render inadvisable, in the reasonable good
faith judgment of First Source, the consummation of the Merger; (v) no
proceeding initiated by a Governmental Entity seeking an Injunction shall be
pending; (vi) First Source shall have received an opinion of its counsel,
substantially to the effect that, on the basis of facts, representations and
assumptions set forth in such opinion, which are consistent with the state of
facts existing at the Effective Time, the Merger and the Subsidiary Bank
Merger will each be treated as reorganizations within the meaning of Section
368(a) of the Code (see "--Certain Federal Income Tax Consequences of the
Merger" below); (vii) First Source shall have received a customary legal
opinion from counsel for Pulse; (viii) First Source shall have received a
letter addressed to First Source, dated as of the Effective Time, from First
Source's independent public accountants to the effect that the Merger will
qualify for pooling of interests accounting treatment unless such firm advises
First Source that it is unable to issue a letter to such effect solely by
reason of First Source having exercised its right to purchase Pulse Common
Stock pursuant to the Stock Option Agreement; (ix) First Source shall have
received from Pulse's independent public accountants certain customary letters
with respect to certain financial information of Pulse; and (x) nothing shall
have come to the attention of First Source which would preclude consummation
of the Subsidiary Bank Merger.     
   
  The Merger Agreement defines a "Material Adverse Effect," when applied to a
party to the Merger Agreement, as a material adverse effect on the business,
properties, assets, liabilities, results of operations or financial condition
of such party and its subsidiaries taken as a whole, other than any such
effect attributable to or resulting from general economic conditions.     
   
  The obligations of Pulse to effect the Merger are further subject to the
satisfaction, or waiver by Pulse, of the following conditions: (i) the
representations and warranties of First Source contained in the Merger
Agreement shall be true and correct in all material respects as of the date of
the Merger Agreement and (except to the extent that such representations and
warranties relate to an earlier date) as of the Effective Time as though made
at and as of the Effective Time, provided, that for purposes of determining
the satisfaction of the condition described in this clause (i), that the
representations and warranties of First Source will be deemed true and correct
in all material respects unless the failure or failures of such
representations and warranties to be so true and correct, individually or in
the aggregate, represent a material adverse change from the business, assets,
financial condition or results of operations of First Source and its
subsidiaries taken as a whole as represented in the Merger Agreement; (ii)
First Source shall have performed in all material respects all obligations
required to be performed by it under the Merger Agreement at or prior to the
Effective Time; (iii) the consent, waiver or approval of each person (other
than the Governmental Entities) whose consent, waiver or approval shall be
required in connection with the transactions contemplated thereby under any
agreement to which First Source or any of its subsidiaries is a party or is
otherwise bound, except those for which the failure to obtain such consents,
    
                                      46
<PAGE>
 
   
waivers and approvals would not have a material adverse effect on the economic
or business benefits of transactions contemplated by the Merger Agreement,
shall have been obtained; (iv) no proceeding initiated by any Governmental
Entity seeking an Injunction shall be pending; (v) Pulse shall have received
from its counsel an opinion dated as of the Effective Time, substantially to
the effect that for Federal income tax purposes the Merger and the Subsidiary
Bank Merger each be treated as reorganizations within the meaning of Section
368(a) of the Code (see "--Certain Federal Income Tax Consequences of the
Merger" below); (vi) Pulse shall have received a customary legal opinion from
counsel to First Source and (vii) First Source shall have received a letter
addressed to First Source, dated as of the Effective Time, from First Source's
independent public accountants to the effect that the Merger will qualify for
pooling of interests accounting treatment unless such firm advises First
Source that it is unable to issue a letter to such effect solely by reason of
First Source having exercised its right to purchase Pulse Common Stock
pursuant to the Stock Option Agreement.     
 
  No assurance can be provided as to when, or whether, the regulatory consents
and approvals necessary to consummate the Merger and the Subsidiary Bank
Merger will be obtained or whether all of the other conditions precedent to
the Merger will be satisfied or waived by the party permitted to do so. See
"--Regulatory Approvals Required for the Merger" below. If the Merger is not
effected on or before March 31, 1999, the Merger Agreement may be terminated
by a vote of a majority of the Board of Directors of either First Source or
Pulse, unless the failure to effect the Merger by such date is due to the
breach of the Merger Agreement by the party seeking to terminate the Merger
Agreement.
 
REGULATORY APPROVALS REQUIRED FOR THE MERGER
 
  Consummation of each of the Merger and the Subsidiary Bank Merger is subject
to a number of regulatory approvals and consents.
   
  Pursuant to the Bank Merger Act, the Home Owners' Loan Act and the OTS
Regulations promulgated thereunder, the Merger is subject to the approval of
the OTS. First Source filed an application for approval of the Merger with the
OTS on October 6, 1998. This application is currently under review by the OTS.
The transaction is also subject to a waiver of the OTS one-year restriction on
acquisitions by First Source from the date of the April 9, 1998 consummation
of the 1998 Conversion and Reorganization. There can be no assurance as to the
timing of such approval or that the OTS will approve the Merger or grant the
waiver. The OTS is required to evaluate the applications by taking into
consideration, among other things, the capital level of the resulting
institution, the financial and managerial resources and future prospects of
the institutions involved, the convenience and needs of the communities to be
served and the conformity of the transaction to applicable law, regulation and
supervisory policies. In addition, the OTS may not approve any proposed
acquisition (i) which would result in a monopoly or which would be in
furtherance of any combination or conspiracy to monopolize or attempt to
monopolize the savings and loan business in any part of the United States or
(ii) which in any section of the country may have the effect of substantially
lessening competition or tending to create a monopoly or which in any manner
would be in restraint of trade, unless the OTS finds that the anti-competitive
effects of the proposed acquisition are clearly outweighed in the public
interest by the probable effect of the acquisition in meeting the convenience
and needs of the community to be served. Under the Community Reinvestment Act
of 1977 (the "CRA"), the OTS must take into account First Savings' record of
performance in meeting the credit needs of the entire community, including
low- and moderate-income neighborhoods, served by First Savings. The OTS also
considers, among other things, the fairness and disclosure of the plan
(including compensation to officers, directors and controlling persons of the
disappearing association by the surviving association), the justification,
need for and compensation to be paid to any advisory board, fees paid to each
person or firm rendering legal or other professional services in connection
with a merger and the accounting and tax treatment of the Merger. The
regulations of the OTS also provide for the publication of notice and the
opportunity for public comments relating to the application for approval
discussed above.     
 
  In addition, under federal law, a period of 30 days must expire following
approval by the OTS within which period the Department of Justice may file
objections to the Merger under the federal antitrust laws. The post-
 
                                      47
<PAGE>
 
approval waiting period may be reduced by the OTS to 15 days, with the
concurrence of the Department of Justice. The Department of Justice could take
such action under the antitrust laws as it deems necessary or desirable in the
public interest, including seeking to enjoin the Merger unless divestiture of
an acceptable number of branches to a competitively suitable purchaser could
be made. While First Source believes that the likelihood of such action by the
Department of Justice is remote in this case, there can be no assurance that
the Department of Justice will not initiate such proceeding, or that the
Attorney General of the State of New Jersey will not challenge the Merger, or
if such proceeding is instituted or challenge is made, as to the result
thereof.
   
  The Merger is also subject to the prior approval of the Commissioner of the
New Jersey Department of Banking and Insurance ("Department"). First Source
filed an application for approval of the Merger with the New Jersey Banking
Department on October 20, 1998. This application is currently under review by
the Banking Department. There can be no assurance as to the timing of such
approval or that the Banking Department will approve the Merger. In
determining whether to approve the application for the Merger of Pulse Bank
with and into First Savings, the Department will consider, among other
factors, whether the Merger would be consistent with adequate or sound banking
and would not result in concentration of assets beyond limits consistent with
effective competition, and whether the Merger would result in such a lessening
of competition as to be injurious to the interest of the public or tend toward
monopoly. The Department will also consider the public interest and the needs
and convenience thereof. Further, it is the policy of the State of New Jersey
to ensure the safe and sound conduct of banking organizations, to conserve
assets of banking organizations, to prevent hoarding of money, to eliminate
unsound and destructive competition among banking organizations and to
maintain public confidence in the business of banking and protect the public
interest and the interests of depositors, creditors and stockholders, and such
factors will be considered by the Commissioner in connection with First
Source's application.     
 
  First Source is not aware of any other regulatory approvals that would be
required for consummation of the Merger or the Subsidiary Bank Merger, except
as described above. Should any other approvals be required, it is presently
contemplated that such approvals would be sought. There can be no assurance
that any other approvals, if required, will be obtained.
 
  Applications have been submitted seeking the approvals of OTS and the
Department. The Merger cannot proceed in the absence of the requisite
regulatory approvals. See "--Conditions to the Merger" and "--Waiver and
Amendment; Termination." There can be no assurance that such regulatory
approvals will be obtained, and if obtained, there can be no assurance as to
the date of any such approval. There can also be no assurance that any such
approvals will not contain a Burdensome Condition which causes such approvals
to fail to satisfy the conditions set forth in the Merger Agreement and
described above under "--Conditions to the Merger." There can likewise be no
assurance that the Department of Justice or the New Jersey State Attorney
General will not challenge the Merger or, if such a challenge is made, as to
the result thereof.
 
CONDUCT OF BUSINESS PENDING THE MERGER
 
  Pursuant to the Merger Agreement, Pulse has agreed that until the Effective
Time, except as provided in the Merger Agreement, the Subsidiary Bank Merger
Agreement, the Stock Option Agreement or with the prior consent of First
Source, Pulse and its subsidiaries will carry on their respective businesses
in the ordinary course consistent with past practice and consistent with
prudent banking practices. Pulse has agreed to use its best efforts to (x)
preserve its business organization and that of its subsidiaries' intact, (y)
keep available to itself and First Source the present services of its and its
subsidiaries' employees and (z) preserve for itself and First Source the
goodwill of its and its subsidiaries' customers and others with whom business
relationships exist.

Pulse's business pending consummation of the Merger. Among other things, the
Merger Agreement provides that, except as provided in

the Merger Agreement or with the prior written consent of First Source, Pulse
and its subsidiaries may not: (i) solely in the case of Pulse, declare or pay
any dividends on, or make other distributions in respect of, any of its
capital stock, other than normal quarterly dividends in an amount of no more
than $0.20 per share of Pulse Common Stock, except that on or after January 1,
1999, Pulse may increase the quarterly dividends to no more than $0.225 per
share; (ii)(a) split, combine or reclassify any shares of its capital stock or
(b) repurchase, redeem or otherwise acquire (except for the acquisition of
Trust Account Shares and DPC Shares) any shares of the capital stock of Pulse

authorize or propose the issuance, delivery or sale of, any shares of its

enter into any new line of business; (vii) subject to certain exceptions,

Subsidiary Bank Merger Agreement, except as may be required by applicable law;
(ix) change its methods of accounting in effect at September 30, 1997, subject

the ordinary course of business consistent with past practice or except as
required by applicable law, increase in any manner the compensation or fringe
benefits of any director, officer or employee and except for continuation of
contributions to Pulse's retirement plan, not to exceed $45,000 per quarter;
(xi) take or cause to be taken any action that would cause the Merger to fail
to qualify (a) for pooling of interests accounting treatment or (b) as a tax-
free reorganization under Section 368(a) of the Code, except that nothing
contained in the Merger Agreement will limit the ability of First Source to
exercise its rights under the Stock Option Agreement; (xii) dispose or agree
to dispose of its material assets, properties or other rights or agreements;

or office space to which Pulse or any of its subsidiaries is a party or by
which Pulse or any of its subsidiaries or their respective property is bound;
(xxii) take any action which would cause the termination or cancellation by
the FDIC of insurance in respect of Pulse's deposits; or (xxiii) agree to do
any of the foregoing.     
 
  Pursuant to the Merger Agreement, First Source has also agreed that until
the Effective Time, except as provided in the Merger Agreement, the Subsidiary
Bank Merger Agreement, or with the prior written consent of Pulse, First
Source and its subsidiaries will carry on their respective businesses in the
ordinary course consistent with prudent banking practices and shall use all
reasonable efforts to preserve intact their present business organizations and
relationships. The Merger Agreement also provides, among other things, that
First Source will not: (i) declare, pay or make any extraordinary or special
dividends or distributions in respect of its capital stock, except that
nothing contained in the Merger Agreement will prohibit First Source from
increasing the quarterly cash dividend on the First Source Common Stock; (ii)
take any action that is intended or may reasonably be expected to result in
any of its representations and warranties set forth in the Merger Agreement
being or
 
                                      49

becoming untrue in any material respect, or in any of the conditions to the
Merger not being satisfied, or in a violation of any provision of the Merger
Agreement or the Subsidiary Bank Merger Agreement, except as may be required
by applicable law; (iii) change its methods of accounting in effect at
December 31, 1997, subject to certain exceptions; (iv) take or cause to be
taken any action that would cause the Merger to fail to qualify (a) for
pooling of interests accounting treatment or (b) as a tax-free reorganization
under Section 368 of the Code, except that nothing contained in the Merger
Agreement will limit the ability of First Source to exercise its rights under
the Stock Option Agreement; (v) take any action which would cause the
termination or cancellation by the FDIC of insurance in respect of First
Source's deposits; or (vi) agree to do any of the foregoing.     
 
WAIVER AND AMENDMENT; TERMINATION
 
  Prior to the Effective Time, any provision of the Merger Agreement may be
waived by the party benefitted by the provision or, subject to applicable law,
amended or modified (including the structure of the transaction) by an
agreement in writing approved by the Boards of Directors of First Source and
Pulse, provided that, after the vote of the stockholders of Pulse, the Merger
Agreement may not be amended, without further approval of such stockholders,
to reduce the amount or change the form of the consideration to be received by
Pulse stockholders other than as contemplated by the Merger Agreement.
 
  The Merger Agreement may be terminated at any time prior to the Effective
Time, either before or after approval of the matters presented in connection
with the Merger by the stockholders of both Pulse and First Source, as
follows: (i) by the mutual consent of First Source and Pulse if the Boards of
Directors of each so determines; (ii) by either First Source or Pulse upon
written notice to the other (a) 60 days after the date on which any request or
application for a Requisite Regulatory Approval is denied or withdrawn at the
request of the Governmental Entity which must grant such approval, unless
within such 60-day period a petition for rehearing or an amended application
has been filed with the applicable Governmental Entity (or unless the failure
to obtain the necessary regulatory approval is due to the failure of the party
seeking to terminate the Merger Agreement to perform or observe its covenants
and agreements set forth in the Merger Agreement) or (b) if any Governmental
Entity of competent jurisdiction issues a final nonappealable order enjoining
or otherwise prohibiting the consummation of any of the transactions
contemplated by the Merger Agreement; (iii) by either First Source or Pulse if
its Board of Directors so determines, in the event that the Merger has not
been consummated by March 31, 1999, unless the failure to consummate the
Merger is due to a breach of the Merger Agreement by the party seeking to
terminate the Merger Agreement; (iv) by either First Source or Pulse (provided
that the terminating party is not in breach of its obligations in the Merger
Agreement with respect to the meeting of its stockholders to approve the
Merger Agreement), if any approval of the stockholders of either of First
Source or Pulse required for consummation of the Merger Agreement shall not
have been obtained; (v) by either First Source or Pulse in the event of (a) a
material breach by the other of any of its representations or warranties
contained in the Merger Agreement which is not cured within 30 days after
written notice of such breach is given to the breaching party or which breach,
by its nature, cannot be cured prior to the Effective Time or (b) a material
breach of any of the covenants or agreements contained in the Merger Agreement
by the other which is not cured within 30 days after written notice of such
breach is given to the breaching party; (vi) by Pulse, by action of its Board
of Directors, by giving written notice of such election to First Source within
two trading days after the Valuation Date, in the event the Average Closing
Price is less than $8.50, provided that no right of termination will arise
under this provision if First Source elects within five business days of
receipt of such written notice to increase the Exchange Ratio such that the
value of the First Source Common Stock (valued at the Average Closing Price)
to be paid in respect of each share of Pulse Common Stock is $32.00 (see "--
Exchange Ratio" above); or (vii) by First Source, by action of its Board of
Directors, by giving written notice of such election to Pulse within two
trading days after the Valuation Date, in the event the Average Closing Price
is greater than $11.50, provided that no right of termination will arise under
this provision if Pulse elects within five business days, of receipt of such
written notice to decrease the Exchange Ratio such that the value of the First
Source Common Stock is $36.80 (see "Exchange Ratio" above); (viii) by First
Source if the
 
                                      50
<PAGE>
 
   
Board of Directors of Pulse does not publicly recommend in the Joint Proxy
Statement/Prospectus that Pulse's stockholders approve and adopt this
agreement or if after recommending in the Joint Proxy Statement/Prospectus
that stockholders approve and adopt this agreement, the Pulse Board shall have
withdrawn, modified or amended such recommendation in any respect materially
adverse to First Source.     
   
  In the event of the termination of the Merger Agreement by either First
Source or Pulse, neither First Source nor Pulse will have any further
obligations under the Merger Agreement except (i) for certain specified
provisions of the Merger Agreement relating to confidentiality and expenses
and (ii) that no party will be relieved or released from any liabilities or
damages arising out of its willful breach of any provisions of the Merger
Agreement. In addition, if the Merger Agreement is terminated subsequent to
the occurrence of a Purchase Event (as defined hereinafter) or is terminated
by First Source for a breach of covenant by Pulse, and within 12 months
following such termination a Purchase Event occurs, then in addition to any
other amounts payable or stock issuable by Pulse pursuant to the Merger
Agreement or the Stock Option Agreement, as the case may be, Pulse must pay
First Source a termination fee of $3.2 million. Additionally, the maximum
aggregate cost of exercising the Option (as defined below) is $3.78 million.
The difference between that cost and the subsequent sale price of the
underlying Pulse Common Stock would be an additional benefit to First Source.
See "CERTAIN RELATED TRANSACTIONS--Termination Fee; Increase in Exercise
Price."     
 
NO SOLICITATION OF TRANSACTIONS
 
  Pulse has agreed in the Merger Agreement that neither it nor any of its
subsidiaries will authorize or permit any of its officers, directors,
employees or agents to directly or indirectly solicit, initiate or encourage
any inquiries relating to, or the making of any proposal which constitutes, a
"takeover proposal" (as defined below), or, except to the extent legally
required for the discharge of the fiduciary duties of the Pulse Board,
recommend or endorse any takeover proposal, or participate in any discussions
or negotiations, or provide third parties with any non-public information,
relating to any such inquiry or proposal or otherwise facilitate any effort or
attempt to make or implement a takeover proposal, provided that Pulse may
communicate information about any such takeover proposal to its stockholders
if, in the judgment of the Pulse Board, based upon the advice of outside
counsel, such communication is required under applicable law; Pulse has agreed
to cease any activities, discussions or negotiations previously conducted with
any parties other than First Source with respect to any of the foregoing; it
will notify First Source immediately if any such inquiries or proposals are
received by, any such information is requested from, or any such negotiations
or discussions are sought to be initiated or continued with it, and will
promptly inform First Source in writing of the relevant details with respect
to the foregoing. As used in the Merger Agreement, "takeover proposal" means
any tender or exchange offer, proposal for a merger, consolidation or other
business combination involving Pulse or any subsidiary of Pulse or any
proposal or offer to acquire in any manner a substantial equity interest in,
or a substantial portion of the assets of, Pulse or any subsidiary of Pulse
other than the transactions contemplated or permitted by the Merger Agreement,
the Subsidiary Bank Merger Agreement and the Stock Option Agreement.
 
RESALES OF FIRST SOURCE COMMON STOCK RECEIVED IN THE MERGER
 
  The shares of First Source Common Stock to be issued in the Merger will be
registered under the Securities Act and will be freely transferable under the
Securities Act, except for shares issued to any Pulse stockholder who may be
deemed to be an "affiliate" of Pulse for purposes of Rule 145 under the
Securities Act. Affiliates may not sell their shares of First Source Common
Stock acquired in connection with the Merger except pursuant to an effective
registration statement under the Securities Act covering such shares or in
compliance with Rule 145 or another applicable exemption from the registration
requirements of the Securities Act. This Joint Proxy Statement/Prospectus does
not cover any resales of First Source Common Stock received in the Merger by
persons who may be deemed to be affiliates of Pulse. Persons who may be deemed
to be affiliates of Pulse generally include individuals or entities that
control, are controlled by or are under common control with Pulse, and may
include certain officers and directors as well as principal stockholders of
Pulse.

<PAGE>
 
  Commission guidelines regarding qualifying for the pooling of interests
method of accounting also limit sales by affiliates of the acquiring and
acquired company in a business combination. Commission guidelines indicate
further that the pooling of interests method of accounting will generally not
be challenged on the basis of sales by affiliates of the acquiring or acquired
company if they do not dispose of any of the shares of the corporation they
own or shares of a corporation they receive in connection with a merger during
the period beginning 30 days before the effective date of the merger and
ending when financial results covering at least 30 days of post-merger
operations of the combined entity have been published.
 
  First Source and Pulse have each agreed in the Merger Agreement to use their
best efforts to cause each person who is an affiliate (for purposes of Rule
145 of the Securities Act and for purposes of qualifying the Merger for
pooling of interests accounting treatment) of such party to deliver to the
other party a written agreement intended to ensure compliance with the
Securities Act and preserve the ability to treat the Merger as a pooling of
interests.
 
STOCK EXCHANGE LISTING
 
  The First Source Common Stock is listed on the Nasdaq National Market. First
Source has agreed to cause the shares of First Source Common Stock to be
issued in the Merger to be approved for listing on the Nasdaq National Market,
subject to official notice of issuance, prior to or at the Effective Time. The
obligations of the parties to consummate the Merger are subject to approval
for listing by the Nasdaq National Market of such shares. See "--Conditions to
the Merger" above.
 
ANTICIPATED ACCOUNTING TREATMENT
 
  The Merger is expected to qualify as a pooling of interests for accounting
and financial reporting purposes. Under this method of accounting, the
recorded amount of assets and liabilities of First Source and Pulse will be
combined at the Effective Time and carried forward at their previously
recorded amounts and the stockholders' equity accounts of First Source and
Pulse will be combined on First Source's consolidated balance sheet. Income
and other financial statements of First Source issued after the Effective Time
will be restated retroactively to reflect the consolidated operations of First
Source and Pulse as if First Source and Pulse have always been combined.
 
  The Merger Agreement provides that a condition to First Source's obligation
to consummate the Merger is the receipt of a letter from First Source's
independent accountants to the effect that the Merger qualifies for pooling of
interests accounting treatment unless such firm advises First Source that it
is unable to issue a letter to such effect solely by reason of First Source
having exercised its right to purchase Pulse Common Stock pursuant to the
Stock Option Agreement. See "--Conditions to the Merger" above.
 
  The issuance of shares of Pulse Common Stock pursuant to the Stock Option
Agreement may prevent the Merger from qualifying as a pooling of interests for
accounting and financial reporting purposes. See "CERTAIN RELATED
TRANSACTIONS--Stock Option Agreement; Termination Fee."
 
  For information concerning certain restrictions to be imposed on the
transferability of First Source Common Stock to be received by affiliates in
order, among other things, to ensure the availability of pooling of interests
accounting treatment, see "--Resales of First Source Common Stock Received in
the Merger" above.
 
CERTAIN FEDERAL INCOME TAX CONSEQUENCES OF THE MERGER
 
  The following is a discussion of the material federal income tax
consequences of the Merger and the Subsidiary Bank Merger to First Source,
Pulse and holders of Pulse Common Stock. The discussion is based upon the
Code, Treasury regulations, Internal Revenue Service (the "Service") rulings,
and judicial and administrative decisions in effect as of the date hereof, all
of which are subject to change at any time, possibly with retroactive effect.
This discussion assumes that the Pulse Common Stock is held as a "capital
asset" within the meaning of Section 1221 of the Code (i.e., property
generally held for investment). In addition, this
 
                                      52
<PAGE>
 
discussion does not address all of the tax consequences that may be relevant
to a holder of Pulse Common Stock in light of his or her particular
circumstances or to holders subject to special rules, such as foreign persons,
financial institutions, tax-exempt organizations or insurance companies. The
opinions of such counsel referred to in this section will be based on facts
existing at the Effective Time, and in rendering such opinions, such counsel
will require and rely upon representations contained in certificates of
officers of First Source, Pulse and others.
 
  HOLDERS OF PULSE COMMON STOCK SHOULD CONSULT THEIR TAX ADVISORS AS TO THE
PARTICULAR TAX CONSEQUENCES TO THEM OF THE MERGER, INCLUDING THE APPLICABILITY
AND EFFECT OF ANY FEDERAL, STATE, LOCAL AND FOREIGN INCOME AND OTHER TAX LAWS.
 
  It is a condition to the obligation of First Source to consummate the Merger
that First Source and Pulse shall have received an opinion from Patton Boggs
LLP, counsel to First Source, that the Merger and the Subsidiary Bank Merger
will each be treated as reorganizations within the meaning of Section 368(a)
of the Code and, accordingly, for federal income tax purposes, that:
 
    i) no gain or loss will be recognized by First Source as a result of the
  Merger;
 
    ii) no gain or loss will be recognized by First Savings Bank as a result
  of the Merger;
 
    iii) no gain or loss will be recognized by Pulse as a result of the
  Merger;
 
    iv) no gain or loss will be recognized by Pulse Bank as a result of the
  Subsidiary Bank Merger;
 
    v) no gain or loss will be recognized by the stockholders of Pulse who
  exchange all of their Pulse Common Stock solely for First Source Common
  Stock pursuant to the Merger (except with respect to cash received in lieu
  of a fractional share interest in First Source Common Stock); and
 
    vi) the aggregate tax basis of the First Source Common Stock received by
  a holder of Pulse Common Stock in the Merger will be the same as the
  aggregate tax basis of the Pulse Common Stock surrendered in exchange
  therefor (reduced by any amount allocable to a fractional share interest in
  First Source Common Stock for which cash is received).
 
  The holding period of the First Source Common Stock received by Pulse
Stockholders pursuant to the Merger will include the period during which the
Pulse Common Stock was held as a capital asset on the date of the Merger.
Based upon the current ruling position of the Service, cash received by a
holder of Pulse Common Stock in lieu of a fractional share interest in First
Source Common Stock will be treated as received in exchange for such
fractional share interest, and gain or loss will be recognized for federal
income tax purposes measured by the difference between the amount of cash
received and the portion of the basis of the share of Pulse Common Stock
allocable to such fractional share interest. Such gain or loss should be long-
term capital gain or loss if such share of Pulse Common Stock has been held
for more than one year at the Effective Time.
 
  Pursuant to the Subsidiary Bank Merger Agreement, Pulse Bank will be merged
with and into First Savings Bank, and, consequently, will no longer be
entitled to use the reserve method for computing and deducting its losses for
bad debts.
 
NO APPRAISAL RIGHTS
   
  Pursuant to Article 14A:11-1 of the New Jersey Business Corporations Act,
the stockholders of a constituent corporation in a merger generally are not
entitled to appraisal rights if (a) the shares of stock they own are, as of
the record date fixed to determine stockholders entitled to notice of and to
vote at the meeting to act upon the agreement providing for such merger,
either listed on a national securities exchange or held by more than
1,000 stockholders or (b) pursuant to a plan of merger such stockholders will
receive: (i) cash; (ii) shares of stock which are either listed on a national
securities exchange or held of record by more than 1,000 stockholders; or
(iii) any combination of (i) and (ii). Pulse stockholders are not entitled to
appraisal rights in connection with the Merger because there are more than
1,000 holders of record of First Source Common Stock.     
 
                                      53
<PAGE>
 
CONSOLIDATION OF OPERATIONS; PROJECTED COST SAVINGS
   
  First Source expects to achieve significant cost savings subsequent to the
Merger. The cost savings will be derived from implementation of operating
synergies, including reductions in compensation and other employee benefit
expenses. Further, the separate corporate existence of Pulse will cease with
the consummation of the Merger. Consequently, operating costs associated with
requirements imposed on Pulse as a publicly held entity will also be
eliminated. The aggregate annual pre-tax cost savings are estimated to range
between $2.4  million to $2.8 million. Management of First Source believes
that realization of these cost savings will occur by December 31, 1999. There
can be no assurance as to when, or whether, the cost savings will be realized.
Such realization will depend upon, among other things, the regulatory and
economic environment, business changes implemented by First Source management
and other factors, many of which are beyond the control of First Source.     
 
MERGER AND RESTRUCTURING CHARGES
   
  A non-recurring merger and restructuring charge estimated in the range of
$5.5 to $5.9 million, before tax effect, will be made upon consummation of the
Merger. It is expected that the charge will be made in the quarter in which
the Merger is consummated. Merger expenses of approximately $1.3 million for
investment banking and professional fees are included in such estimated
restructuring charge. The restructuring charge primarily includes severance
and employee related expenses, and, to a lesser extent, facility and system
integration costs and other general costs. See "THE MERGER--Certain Federal
Income Tax Consequences of the Merger."

                         CERTAIN RELATED TRANSACTIONS
 
TERMINATION FEE
 
  The following is a summary of the material provisions of certain provisions
of the Merger Agreement (which is attached hereto as Annex A) which provide
for the payment by Pulse to First Source of a $3.2 million fee (the
"Termination Fee") in certain circumstances. The following summary is
qualified in its entirety by reference to the Stock Option Agreement and the
relevant provisions of the Merger Agreement.
 
  Purchase Events. The Option is exercisable, and the Termination Fee payable,
only upon the occurrence of one of the following events (each a "Purchase
Event"):
     
    (a) Pulse authorizes, recommends, publicly proposes, or enters into an
  agreement with any person (other than First Source or any of its
  subsidiaries) to (i) effect a merger, consolidation or similar transaction
  involving Pulse or any of its subsidiaries (other than internal mergers,
  reorganizations, consolidations or dissolutions involving only existing
  subsidiaries), (ii) sell, lease, exchange or otherwise dispose of assets of
  Pulse or any of its subsidiaries representing 25% or more of the
  consolidated assets of Pulse and its subsidiaries, or (iii) issue, sell or
  otherwise dispose of (including by merger, consolidation, share exchange or
  similar transaction) securities representing 25% or more of the voting
  power of Pulse or any of its subsidiaries (any of the foregoing, an
  "Acquisition Transaction");     
     
    (b) any person (other than First Source or its subsidiaries) shall have
  acquired Beneficial Ownership (as defined in Rule 13d-3 promulgated under
  the Exchange Act) of, or the right to acquire Beneficial Ownership of, or
  any Group (as defined in the Exchange Act) shall have been formed which has
  acquired Beneficial Ownership of, or has the right to acquire Beneficial
  Ownership of, 25% or more of the then outstanding shares of Pulse Common
  Stock;     
     
    (c) any person (other than First Source or any subsidiary of First
  Source) shall have (i) commenced (as such term is defined in Rule 14d-2
  under the Exchange Act) or shall have filed a registration statement under
  the Securities Act with respect to a Tender Offer or Exchange Offer to
  purchase any shares of Pulse Common Stock such that, upon consummation of
  such offer, such person would own or control 25% or more of the then
  outstanding shares of Pulse Common Stock (such an offer being referred to
  herein as a "Tender Offer" or an "Exchange Offer," respectively);     
 
    (d) the stockholders of Pulse shall not have approved the Merger
  Agreement at the meeting of such stockholders held for the purpose of
  voting on the Merger Agreement, or such meeting shall not have been held or
  shall have been cancelled prior to termination of the Merger Agreement, in
  each case after it shall have been publicly announced that any person
  (other than First Source or any subsidiary of First Source) shall have
  made, or disclosed an intention to make, a proposal to engage in an
  Acquisition Transaction; or
 
    (e) Pulse's Board of Directors shall not have recommended to Pulse's
  stockholders that such stockholders vote in favor of the approval of the
  Merger Agreement and the transactions contemplated thereby or shall have
  withdrawn or modified such recommendation in a manner adverse to First
  Source.
 
  Termination Fee; Increase in Exercise Price. The Merger Agreement provides
that in addition to the rights granted to First Source under the Stock Option
Agreement, in the event the Merger Agreement (i) is terminated subsequent to
the occurrence of a Purchase Event or (ii) is terminated by First Source as a
result of a breach by Pulse of its covenants under the Merger Agreement, and
within 12 months after such termination by First Source a Purchase Event shall
occur, then Pulse must pay to First Source the Termination Fee of $3.2
million.
   
  The Stock Option Agreement provides that in addition to any other amounts
payable by First Source to Pulse upon the exercise of the option, upon the
first such exercise, First Source will pay to Pulse an amount, if any, by
which (i) $1,055,600 plus the product of (A) the total number of Option Shares
(620,940) and (B) the difference between the Market/Tender Offer Price (as
defined below) and the Purchase Price exceeds (ii) $32.00, provided, however,
that in no event will the amount payable pursuant to this provision exceed
$3.78 million. The "Market/Tender Offer Price" means the higher of the highest
price per share at which a Tender Offer or     
 
                                      55
<PAGE>
 
   
Exchange Offer has been made by any person other than First Source or any
affiliate of First Source or person acting in concert in any respect with
First Source for at least 25% of the shares of Pulse Common Stock then
outstanding or the highest closing sales price per share of Pulse Common Stock
quoted on The Nasdaq Stock Market (or if Pulse Common Stock is not quoted on
The Nasdaq Stock Market, the highest bid price per share as quoted on the
principal trading market or securities exchange on which such shares are
traded as reported by a recognized source) within the six month period
immediately preceding the execution of the Stock Option Agreement.     
       
  Effect of Stock Option Agreement and Termination Fee. The Stock Option
Agreement and the Termination Fee are intended to increase the likelihood that
the Merger will be consummated in accordance with the terms of the Merger
Agreement. Consequently, certain aspects of the Stock Option Agreement and the
Termination Fee may have the effect of discouraging persons who might now or
prior to the Effective Time be interested in acquiring all of or a significant
interest in Pulse from considering or proposing such an acquisition, even if
such persons were prepared to pay a higher price per share for Pulse Common
Stock than the price per share implicit in the Exchange Ratio. The acquisition
of Pulse or an interest in Pulse, or an agreement to do either, could cause
the Option to become exercisable and the Termination Fee to become payable.
The existence of the Option and the Termination Fee could significantly
increase the cost to a potential acquiror of acquiring Pulse compared to its
cost had the Stock Option Agreement and the Merger Agreement not been entered
into. Such increased cost might discourage a potential acquiror from
considering or proposing an acquisition or might result in a potential
acquiror proposing to pay a lower per share price to acquire Pulse than it
might otherwise have proposed to pay. Moreover, following consultation with
First Source's independent accountants, the management of First Source
believes that the exercise of the Option is likely to prohibit any acquiror of
Pulse from accounting for any acquisition of Pulse using the pooling of
interests accounting method for a period of two years. Accordingly, the
existence of the Stock Option Agreement may deter significantly, or completely
preclude, an acquisition of Pulse by certain other banking organizations. The
Pulse Board took this factor into account before approving the Stock Option
Agreement. See "THE MERGER--Recommendation of the Boards of Directors; Reasons
for the Merger--Pulse."
 
SUBSIDIARY BANK MERGER AGREEMENT
   
  In connection with the Merger, First Savings and Pulse Bank will enter into
a Subsidiary Bank Merger Agreement pursuant to which Pulse Bank will be merged
with and into First Savings, which will continue as a wholly owned subsidiary
of First Source. The Subsidiary Bank Merger Agreement may be terminated by
mutual consent of the parties at any time and will be terminated automatically
in the event the Merger Agreement is terminated.     
 
  THE FOREGOING SUMMARIES OF THE STOCK OPTION AGREEMENT, THE SUBSIDIARY BANK
MERGER AGREEMENT AND THE PROVISIONS OF THE MERGER AGREEMENT RELATING TO THE
TERMINATION FEE ARE QUALIFIED IN THEIR ENTIRETY BY REFERENCE TO SUCH
AGREEMENTS. THE MERGER AGREEMENT IS ATTACHED HERETO AS ANNEX A AND STOCK
OPTION AGREEMENT IS ATTACHED HERETO AS ANNEX B. SEE "INCORPORATION OF CERTAIN
DOCUMENTS BY REFERENCE."
 
                       CERTAIN REGULATORY CONSIDERATIONS
 
GENERAL
   
  First Source is a non-diversified unitary savings and loan holding company
within the meaning of the Home Owners' Loan Act ("HOLA"). As such, First
Source is subject to OTS regulations, examinations, supervision and reporting
requirements. In addition, the OTS has enforcement authority over First Source
and its non-savings institution subsidiaries. Among other things, this
authority permits the OTS to restrict or prohibit activities that are
determined to be a serious risk to the subsidiary savings institution. First
Savings must notify the OTS 30 days before declaring any dividend to First
Source.     
 
                                      56
<PAGE>
 
   
  As a unitary savings and loan holding company, First Source generally is not
restricted under existing laws as to the types of business activities in which
it may engage, provided that First Savings continues to be a Qualified Thrift
Lender ("QTL"). See"--Federal Regulation of Savings Institutions--QTL Test"
for a discussion of the QTL requirements. Upon any non-supervisory acquisition
by First Source of another savings association, First Source would become a
multiple savings and loan holding company (if the acquired institution is held
as a separate subsidiary) and would be subject to extensive limitations on the
types of business activities in which it could engage. The HOLA limits the
activities of a multiple savings and loan holding company and its non-insured
institution subsidiaries primarily to activities permissible for bank holding
companies under Section 4(c)(8) of the Bank Holding Company ("BHC") Act,
subject to the prior approval of the OTS, and to other activities authorized
by OTS regulation. Previously proposed legislation would treat all savings and
loan holding companies as bank holding companies and limit the activities of
such companies to those permissible for bank holding companies.     
 
  The HOLA prohibits a savings and loan holding company, directly or
indirectly, or through one or more subsidiaries, from acquiring more than 5%
of the voting stock of another savings institution, or holding company
thereof, without prior written approval of the OTS and from acquiring or
retaining, with certain exceptions, more than 5% of a non-subsidiary holding
company or savings association. The HOLA also prohibits a savings and loan
holding company from acquiring more than 5% of a company engaged in activities
other than those authorized for savings and loan holding companies by the
HOLA; or acquiring or retaining control of a depository institution that is
not insured by the FDIC. In evaluating applications by holding companies to
acquire savings institutions, the OTS must consider the financial and
managerial resources and future prospects of the company and institution
involved, the effect of the acquisition on the risk to the insurance funds,
the convenience and needs of the community and competitive factors.
 
  The OTS is prohibited from approving any acquisition that would result in a
multiple savings and loan holding company controlling savings institutions in
more than one state, except: (i) the approval of interstate supervisory
acquisitions by savings and loan holding companies, and (ii) the acquisition
of a savings institution in another state if the laws of the state of the
target savings institution specifically permit such acquisitions. The states
vary in the extent to which they permit interstate savings and loan holding
company acquisitions.
   
  First Savings is subject to extensive regulation, examination and
supervision by the Department, as its chartering agency, the OTS, as its
federal banking regulator, and the FDIC, as the deposit insurer. First Savings
is a member of the FHLB System. First Savings' deposit accounts are insured up
to applicable limits by the SAIF managed by the FDIC. First Savings must file
reports with the Commissioner of the Department (the "Commissioner"), the OTS
and the FDIC concerning its activities and financial condition in addition to
obtaining regulatory approvals prior to entering into certain transactions
such as mergers with, or acquisitions of, other financial institutions. There
are periodic examinations by the Department, the OTS and the FDIC to test
First Savings' compliance with various regulatory requirements. This
regulation and supervision establishes a comprehensive framework of activities
in which an institution can engage and is intended primarily for the
protection of the insurance fund and depositors. The regulatory structure also
gives the regulatory authorities extensive discretion in connection with their
supervisory and enforcement activities and examination policies, including
policies with respect to the classification of assets and the establishment of
adequate loan loss reserves for regulatory purposes. Any change in such
policies, whether by the Department, the OTS, the FDIC or the Congress, could
have a material adverse impact on First Source, First Savings and their
operations. First Source, as a savings and loan holding company, is also
required to file certain reports with, and otherwise comply with the rules and
regulations of the OTS and of the Securities and Exchange Commission (the
"SEC") under the federal securities laws.     
   
  Any change in the regulatory structure or the applicable statutes or
regulations, whether by the Department, the OTS, the FDIC or the Congress,
could have a material impact on First Source, First Savings and their
operations. Congress has been considering various proposals to eliminate the
federal thrift charter and abolish     
 
                                      57

the OTS. The outcome of such legislation is uncertain. Therefore, First Source
is unable to determine the extent to which legislation, if enacted, would
affect its business and what charter alternatives will be available at that
time.     
   
  Certain of the regulatory requirements applicable to First Savings and to
First Source are referred to below or elsewhere herein. The description of
statutory provisions and regulations applicable to savings associations set
forth in this Joint Proxy Statement/Prospectus do not purport to be complete
descriptions of such statutes and regulations and their effects on First
Savings and First Source and is qualified in its entirety by reference to such
statutes and regulations.     
 
FEDERAL REGULATION OF SAVINGS INSTITUTIONS
 
  Business Activities. The activities of savings institutions are governed by
the Home Owners' Loan Act, as amended (the "HOLA") and, in certain respects,
the Federal Deposit Insurance Act ("FDI Act") and the regulations issued by
the agencies to implement these statutes. These laws and regulations delineate
the nature and extent of the activities in which savings associations may
engage.
 
  Loans-to-One Borrower. Under the HOLA, savings institutions are generally
subject to the national bank limit on loans-to-one borrower. Generally, this
limit is 15% of First Savings' unimpaired capital and surplus, plus an
additional 10% of unimpaired capital and surplus, if such loan is secured by
readily-marketable collateral, which is defined to include certain financial
instruments and bullion. At June 30, 1998, First Savings' general policy is to
limit loans-to-one borrower to $18.0 million. At June 30, 1998, First Savings'
largest aggregate amount of loans-to-one borrower totaled $13.2 million.
 
  QTL Test. The HOLA requires savings institutions to meet a QTL test. Under
the QTL test, a savings association is required to maintain at least 65% of
its "portfolio assets" (total assets less: (i) specified liquid assets up to
20% of total assets; (ii) intangibles, including goodwill; and (iii) the value
of property used to conduct business) in certain "qualified thrift
investments" (primarily residential mortgages and related investments,
including certain mortgage-backed and related securities) in at least nine
months out of each 12 month period. A savings association that fails the QTL
test must either convert to a bank charter or operate under certain
restrictions. As of June 30, 1998, First Savings maintained 84% of its
portfolio assets in qualified thrift investments and, therefore, met the QTL
test. Recent legislation has expanded the extent to which education loans,
credit card loans and small business loans may be considered as "qualified
thrift investments."
   
  Limitation on Capital Distributions. OTS regulations impose limitations upon
all capital distributions by a savings institution, such as cash dividends,
payments to repurchase or otherwise acquire its shares, payments to
shareholders of another institution in a cash-out merger and other
distributions charged against capital. The rule establishes three tiers of
institutions, which are based primarily on an institution's capital level and
supervisory condition. An institution, such as First Savings, that exceeds all
fully phased-in regulatory capital requirements before and after a proposed
capital distribution ("Tier 1 Bank") and has not been advised by the OTS that
it is in need of more than normal supervision, could, after prior notice to,
but without the approval of the OTS, make capital distributions during a
calendar year equal to the greater of: (i) 100% of its net earnings to date
during the calendar year plus the amount that would reduce by one-half its
"surplus capital ratio" (the excess capital over its fully phased-in capital
requirements) at the beginning of the calendar year; or (ii) 75% of its net
earnings for the previous four quarters. Any additional capital distributions
would require prior OTS approval. In the event First Savings' capital fell
below its capital requirements or the OTS notified it that it was in need of
more than normal supervision, First Savings' ability to make capital
distributions could be restricted. In addition, the OTS could prohibit a
proposed capital distribution by any institution, which would otherwise be
permitted by the regulation, if the OTS determines that such distribution
would constitute an unsafe or unsound practice.     
   
  Liquidity. First Savings is required to maintain an average daily balance of
specified liquid assets equal to a monthly average of not less than a
specified percentage (currently 4%) of its net withdrawable deposit accounts
plus short-term borrowings. Monetary penalties may be imposed for failure to
meet these liquidity requirements. First Savings' average liquidity ratio at
June 30, 1998 was 47%, which exceeded the applicable requirements. First
Savings has never been subject to monetary penalties for failure to meet its
liquidity requirements.     
 
                                      58
<PAGE>
 
  Assessments. Savings institutions are required by regulation to pay
assessments to the OTS and the New Jersey Department of Banking to fund the
various agency's operations and periodic Bank examinations. The assessments
paid by First Savings to these agencies for the six months ended June 30, 1998
and for the years ended December 31, 1997 and 1996 totaled $161,000, $251,000
and $271,000, respectively.
 
  Transactions with Related Parties. First Savings' authority to engage in
transactions with related parties or "affiliates" (i.e., any company that
controls or is under common control with an institution, including First
Source and any non-savings institution subsidiaries that First Source may
establish) is limited by Sections 23A and 23B of the Federal Reserve Act
("FRA"). Section 23A restricts the aggregate amount of covered transactions
with any individual affiliate to 10% of the capital and surplus of the savings
institution and also limits the aggregate amount of transactions with all
affiliates to 20% of the savings institution's capital and surplus. Certain
transactions with affiliates are required to be secured by collateral in an
amount and of a type described in Section 23A and the purchase of low quality
assets from affiliates is generally prohibited. Section 23B generally requires
that certain transactions with affiliates, including loans and asset
purchases, must be on terms and under circumstances, including credit
standards, that are substantially the same or at least as favorable to the
institution as those prevailing at the time for comparable transactions with
non-affiliated companies.
 
  First Savings' authority to extend credit to executive officers, directors
and 10% shareholders ("insiders"), as well as entities such persons control,
is governed by Sections 22(g) and 22(h) of the FRA, and Regulation O
thereunder. Among other things, these regulations require such loans to be
made on terms and conditions substantially the same as those offered to
unaffiliated individuals and not involve more than the normal risk of
repayment. Recent legislation created an exception for loans to insiders made
pursuant to a benefit or compensation program that are widely available to all
employees of the institution and do not give preference to insiders over other
employees. Regulation O also places individual and aggregate limits on the
amounts of loans First Savings may make to insiders based, in part, on First
Savings' capital position, and requires certain board approval procedures to
be followed.
 
  Enforcement. Under the FDI Act, the OTS has primary enforcement
responsibility over savings institutions and has the authority to bring action
against all "institution-affiliated parties," including stockholders, and any
attorneys, appraisers and accountants who knowingly or recklessly participate
in wrongful action likely to have an adverse effect on an insured institution.
Formal enforcement action may range from the issuance of a capital directive
or cease and desist order to removal of officers or directors, receivership,
conservatorship or termination of deposit insurance. Civil penalties cover a
wide range of violations and can amount to $25,000 per day, or $1 million per
day in especially egregious cases. Under the FDI Act, the FDIC has the
authority to recommend to the Director of the OTS that enforcement action
betaken with respect to a particular savings institution. If action is not
taken by the Director, the FDIC has authority to take such action under
certain circumstances. Federal and state law also establishes criminal
penalties for certain violations.
 
  Standards for Safety and Soundness. The FDI Act requires each federal
banking agency to prescribe for all insured depository institutions standards
relating to, among other things, internal controls, information systems and
audit systems, loan documentation, credit underwriting, interest rate risk
exposure, asset growth, and compensation, fees and benefits and such other
operational and managerial standards as the agency deems appropriate. The
federal banking agencies have adopted final regulations and Interagency
Guidelines Establishing Standards for Safety and Soundness ("Guidelines") to
implement these safety and soundness standards. The Guidelines set forth the
safety and soundness standards that the federal banking agencies use to
identify and address problems at insured depository institutions before
capital becomes impaired. The Guidelines address internal controls and
information systems; internal audit system; credit underwriting; loan
documentation; interest rate risk exposure; asset growth; asset quality;
earnings; and compensation, fees and benefits. If the appropriate federal
banking agency determines that an institution fails to meet any standard
prescribed by the Guidelines, the agency may require the institution to submit
to the agency an acceptable plan to achieve compliance with the standard, as
required by the FDI Act. The final regulations establish deadlines for the
submission and review of such safety and soundness compliance plans.
 
                                      59

  Capital Requirements. The OTS capital regulations require savings
institutions to meet three capital standards: a 1.5% tangible capital
standard, a 3% leverage (core capital) ratio and an 8% risk based capital
standard. Core capital is defined as common stockholder's equity (including
retained earnings), certain non-cumulative perpetual preferred stock and
related surplus, minority interests in equity accounts of consolidated
subsidiaries less intangibles other than certain mortgage servicing rights
("MSRs") and credit card relationships. The OTS regulations require that, in
meeting the leverage ratio, tangible and risk-based capital standards
institutions generally must deduct investments in and loans to subsidiaries
engaged in activities not permissible for a national bank. In addition, the
OTS prompt corrective action regulation provides that a savings institution
that has a leverage capital ratio of less than 4% (3% for institutions
receiving the highest CAMEL examination rating) will be deemed to be
"undercapitalized" and may be subject to certain restrictions. See "--Prompt
Corrective Regulatory Action."
   
  The risk-based capital standard for savings institutions requires the
maintenance of total capital (which is defined as core capital and
supplementary capital) to risk-weighted assets of 8%. In determining the
amount of risk-weighted assets, all assets, including certain off-balance
sheet assets, are multiplied by a risk-weight of 0% to 100%, as assigned by
the OTS capital regulation based on the risks OTS believes are inherent in the
type of asset. The components of core capital are equivalent to those
discussed earlier under the 3% leverage standard. The components of
supplementary capital currently include cumulative preferred stock, long-term
perpetual preferred stock, mandatory convertible securities, subordinated debt
and intermediate preferred stock and, within specified limits, the allowance
for loan and lease losses. Overall, the amount of supplementary capital
included as part of total capital cannot exceed 100% of core capital. At June
30, 1998, First Savings met each of its capital requirements, in each case on
a fully phased-in basis.     
 
THRIFT RECHARTERING
 
  Recently enacted legislation provides that the BIF (the deposit insurance
fund that covers most commercial bank deposits) and the SAIF will merge on
January 1, 1999 if there are no more savings associations as of that date.
Several bills have been introduced in the current Congress that would
eliminate the federal thrift charter and the OTS. A bill recently reported by
the House Banking Committee would require federal thrifts to become national
banks or state banks or savings banks within two years after enactment or they
would, by operation of law, become national banks. A national bank resulting
from a converted federal thrift could continue to engage in activities,
including holding any assets, in which it was lawfully engaged on the day
before the date of enactment. Branches operated on the day before enactment
could be retained regardless of their permissibility for national banks.
Subject to a grandfathering provision, all savings and loan holding companies
would become subject to the same regulation and activities restrictions as
bank holding companies. The grandfathering could be lost under certain
circumstances, such as a change in control of the holding company. The
legislative proposal would also abolish the OTS and transfer its functions to
the federal bank regulators with respect to the institutions and to the Board
of Governors of the Federal Reserve Board with respect to the regulation of
holding companies. First Savings is unable to predict whether the legislation
will be enacted or, given such uncertainty, determine the extent to which the
legislation, if enacted, would affect its business. First Savings is also
unable to predict whether the SAIF and BIF will eventually be merged.
 
PROMPT CORRECTIVE REGULATORY ACTION
 
  Under the OTS prompt corrective action regulations, the OTS is required to
take certain supervisory actions against undercapitalized institutions, the
severity of which depends upon the institution's degree of capitalization.
Generally, a savings institution that has a total risk-based capital of less
than 8.0% or a leverage ratio or a Tier 1 capital ratio that is less than 4.0%
is considered to be undercapitalized. A savings institution that has a total
risk-based capital less than 6.0%, a Tier 1 risk-based capital ratio of less
than 3.0% or a leverage ratio that is less than 3.0% is considered to
be"significantly undercapitalized" and a savings institution that has a
tangible capital to assets ratio equal to or less than 2.0% is deemed to be
"critically undercapitalized." Subject to a narrow exception, the banking
regulator is required to appoint a receiver or conservator for an institution
that is critically
 
                                      60
<PAGE>
 
undercapitalized. The regulation also provides that a capital restoration plan
must be filed with the OTS within 45 days of the date an association receives
notice that it is "undercapitalized," "significantly undercapitalized" or
"critically undercapitalized." Compliance with the plan must be guaranteed by
any parent holding company. In addition, numerous mandatory supervisory
actions may become immediately applicable to the institution depending upon
its category, including, but not limited to, increased monitoring by
regulators, restrictions on growth, and capital distributions and limitations
on expansion. The OTS could also take any one of a number of discretionary
supervisory actions, including the issuance of a capital directive and the
replacement of senior executive officers and directors.
 
INSURANCE OF DEPOSIT ACCOUNTS
 
  The FDIC has adopted a risk-based insurance assessment system. The FDIC
assigns an institution to one of three capital categories based on the
institution's financial information, as of the reporting period ending seven
months before the assessment period. The capital categories are (1) well
capitalized, (2) adequately capitalized or (3) undercapitalized. An
institution is also placed in one of three supervisory subcategories within
each capital group. The supervisory subgroup to which an institution is
assigned is based on a supervisory evaluation provided to the FDIC by the
institution's primary federal regulator and information that the FDIC
determines to be relevant to the institution's financial condition and the
risk posed to the deposit insurance funds. An institution's assessment rate
depends on the capital category and supervisory category to which it is
assigned with the most well capitalized, healthy institutions receiving the
lowest rates.
 
  Deposits of First Savings are presently insured by the SAIF. Both the SAIF
and the BIF are statutorily required to be recapitalized to a 1.25% of insured
reserve deposits ratio. First Savings' assessment rate for the six months
ended June 30, 1998 was 6.4 basis points for $100 in insurable deposits and
the regular premium expense for this period was $250,000.
 
  The FDIC has exercised this authority several times in the past and may
raise insurance premiums in the future. If such action is taken by the FDIC,
it could have an adverse effect on the earnings of First Savings.
 
  Under the FDI Act, insurance of deposits may be terminated by the FDIC upon
a finding that the institution has engaged in unsafe or unsound practices, is
in an unsafe or unsound condition to continue operations or has violated any
applicable law, regulation, rule, order or condition imposed by the FDIC or
the OTS. The management of First Savings does not know of any practice,
condition or violation that might lead to termination of deposit insurance.
 
FEDERAL HOME LOAN BANK SYSTEM
 
  First Savings is a member of the FHLB System, which consists of 12 regional
FHLBs. The FHLB provides a central credit facility primarily for member
institutions. First Savings, as a member of the FHLB, is required to acquire
and hold shares of capital stock in the FHLB in an amount at least equal to 1%
of the aggregate principal amount of its unpaid residential mortgage loans and
similar obligations at the beginning of each year, or 1/20 of its advances
(borrowings) from the FHLB, whichever is greater. First Savings was in
compliance with this requirement with an investment in FHLB stock at June 30,
1998 of $8.4 million. FHLB advances must be secured by specified types of
collateral and all long-term advances may only be obtained for the purpose of
providing funds for residential housing finance. At June 30, 1998, First
Savings had $13.0 million in FHLB advances and $81.9 million in repurchase
agreements with the FHLB.
 
  The FHLBs are required to provide funds for the resolution of insolvent
thrifts and to contribute funds for affordable housing programs. These
requirements could reduce the amount of dividends that the FHLBs pay to their
members and could also result in the FHLBs imposing a higher rate of interest
on advances to their members. For the six months ended June 30, 1998 and the
years ended December 31, 1997 and 1996, dividends from FHLB stock to First
Savings amounted to $305,000, $525,000 and $469,000, respectively. If
dividends were reduced, First Savings' net interest income would likely also
be reduced. Further, there can be no assurance that the impact of recent or
future legislation on the FHLBs will not also cause a decrease in the value of
the FHLB stock held by First Savings.

FEDERAL RESERVE SYSTEM
 
  The Federal Reserve Board regulations require savings institutions to
maintain noninterest-earning reserves against their transaction accounts
(primarily NOW and regular checking accounts). The Federal Reserve Board
regulations generally require that reserves be maintained against aggregate
transaction accounts as follows: for accounts aggregating $47.8 million or
less (subject to adjustment by the Federal Reserve Board) the reserve
requirement is 3%; and for accounts greater than $47.8 million, the reserve
requirement is $1.479 million (subject to adjustment by the Federal Reserve
Board between 8% and 14%) against that portion of total transaction accounts
in excess of $47.8 million. The first $4.7 million of otherwise reservable
balances (subject to adjustment by the Federal Reserve Board) are exempted
from the reserve requirements. First Savings is in compliance with the
foregoing requirements. Because required reserves must be maintained in the
form of either vault cash, a noninterest-bearing account at a Federal Reserve
Bank or a pass-through account as defined by the Federal Reserve Board, the
effect of this reserve requirement is to reduce First Savings' interest-
earning assets. FHLB System members are also authorized to borrow from the
Federal Reserve "discount window," but Federal Reserve Board regulations
require institutions to exhaust all FHLB sources before borrowing from a
Federal Reserve Bank.
 
NEW JERSEY LAW
   
  The Commissioner regulates, among other things, the First Savings' internal
business procedures as well as its deposits, lending and investment
activities. The Commissioner must approve changes to First Savings'
Certificate of Incorporation, establishment or relocation of branch offices,
mergers and the issuance of additional stock. In addition, the Commissioner
conducts periodic examinations of First Savings. Certain of the areas
regulated by the Commissioner are not subject to similar regulation by the
FDIC.     
 
  Recent federal and state legislative developments have reduced distinctions
between commercial banks and SAIF-insured savings institutions in New Jersey
with respect to lending and investment authority, as well as interest rate
limitations. As federal law has expanded the authority of federally chartered
savings institutions to engage in activities previously reserved for
commercial banks, New Jersey legislation and regulations ("parity
legislation") have given New Jersey chartered savings institutions, such as
First Savings, the powers of federally chartered savings institutions.
 
  New Jersey law provides that, upon satisfaction of certain triggering
conditions, as determined by the Commissioner, insured institutions or savings
and loan holding companies located in a state which has reciprocal legislation
in effect on substantially the same terms and conditions as stated under New
Jersey law may acquire, or be acquired by New Jersey insured institutions or
holding companies on either a regional or national basis. New Jersey law
explicitly prohibits interstate branching.

                   DESCRIPTION OF FIRST SOURCE CAPITAL STOCK
 
GENERAL
   
  First Source is authorized to issue 85,000,000 shares of Common Stock having
a par value of $.01 per share and 10,000,000 shares of preferred stock having
a par value of $.01 per share (the "Preferred Stock"). At October 30, 1998,
there were 31,838,866 shares of Common Stock and no shares of Preferred Stock
outstanding.     
 
COMMON STOCK
 
  Dividends. First Source can pay dividends out of statutory surplus or from
certain net profits if, as and when declared by its Board of Directors. The
payment of dividends by First Source is subject to limitations which are
imposed by law and applicable regulation. The holders of Common Stock of First
Source are entitled to receive and share equally in such dividends as may be
declared by the Board of Directors of First Source out of funds legally
available therefor. If First Source issues Preferred Stock, the holders
thereof may have a priority over the holders of the Common Stock with respect
to dividends.
 
  Voting Rights. The holders of Common Stock of First Source possess exclusive
voting rights in First Source. They elect First Source's Board of Directors
and act on such other matters as are required to be presented to them under
Delaware law or First Source's Certificate of Incorporation or as are
otherwise presented to them by the Board of Directors. Except with respect to
certain voting limitations for holders of greater than 10% of the First Source
Common Stock, each holder of Common Stock is entitled to one vote per share
and does not have any right to cumulate votes in the election of directors. If
First Source issues Preferred Stock, holders of the Preferred Stock may also
possess voting rights. Certain matters require an 80% stockholder vote.
 
  Liquidation. In the event of any liquidation, dissolution or winding up of
First Source, as holder of First Savings' capital stock, would be entitled to
receive, after payment or provision for payment of all debts and liabilities
of First Savings (including all deposit accounts and accrued interest thereon)
and after distribution of the balance in the special liquidation account
related to First Source's Conversion, all assets of First Savings available
for distribution. In the event of liquidation, dissolution or winding up of
First Source, the holders of its Common Stock would be entitled to receive,
after payment or provision for payment of all its debts and liabilities, all
of the assets of First Source available for distribution. If Preferred Stock
is issued, the holders thereof may have a priority over the holders of the
Common Stock in the event of liquidation or dissolution.
 
  Preemptive Rights. Holders of the Common Stock of First Source will not be
entitled to preemptive rights with respect to any shares which may be issued.
The Common Stock is not subject to redemption.
 
PREFERRED STOCK
 
  None of the shares of First Source's authorized Preferred Stock have been
issued. Such stock may be issued with such preferences and designations as the
Board of Directors may from time to time determine. The Board of Directors
can, without stockholder approval, issue preferred stock with voting,
dividend, liquidation and conversion rights which could dilute the voting
strength of the holders of the Common Stock and may assist management in
impeding an unfriendly takeover or attempted change in control.
 
                       COMPARISON OF STOCKHOLDER RIGHTS
   
  Upon the consummation of the transactions contemplated in the Merger
Agreement, the stockholders of Pulse will become stockholders of First Source.
First Source is a Delaware-chartered corporation, while Pulse is a New Jersey-
chartered corporation. Therefore, the rights presently enjoyed by Pulse's
stockholders under the relevant provisions of the New Jersey Business
Corporation Act ("NJBCA"), the Certificate of Incorporation (the "Pulse
Certificate") and the Bylaws (the "Pulse Bylaws") of Pulse may differ in some
respects from the rights they would have as stockholders of First Source under
the relevant provisions of the Delaware General     
 
                                      63
<PAGE>
 
   
Corporation Law ("DGCL"), First Source's Certificate of Incorporation ("First
Source Certificate") and First Source's Bylaws (the "First Source Bylaws").
This summary contains a list of the material differences, but is not meant to
be relied upon as an exhaustive list or a detailed description of the
provisions discussed and is qualified in its entirety by reference to the
First Source Certificate, the First Source Bylaws, the Pulse Certificate, the
Pulse Bylaws, the DGCL and the NJBCA.     
 
ISSUANCE OF CAPITAL STOCK
   
  Pulse. The Pulse Certificate authorizes the issuance of 10,000,000 shares of
Pulse Common Stock, $1.00 par value per share, and 5,000,000 shares of Serial
Preferred Stock. At October 30, 1998, 3,205,800 shares of Pulse Common Stock
were issued and outstanding, and no shares of preferred stock were issued and
outstanding.     
   
  First Source. The First Source Certificate authorizes the issuance of
85,000,000 shares of Common Stock, $0.01 per value, and 10,000,000 shares of
Preferred Stock, $0.01 par value. At October 30, 1998, 31,838,866 shares of
First Source Common Stock were outstanding and no shares of Preferred Stock
were outstanding.     
 
ADVANCE NOTICE REQUIREMENTS FOR NOMINATIONS OF DIRECTORS AND SHAREHOLDER
PROPOSALS
 
  Pulse. The Pulse Certificate provides that nominations for the election of
directors may be made by any shareholder entitled to vote generally in the
election of directors by following certain procedures set forth therein. In
order for a Pulse shareholder to make a nomination, he or she must give notice
in writing to Pulse not fewer than 60 days prior to the anniversary date of
the immediately preceding annual meeting of shareholders of Pulse. The
shareholder's notice must contain certain information specified by the
Certificate.
   
  First Source. The First Source Certificate contains similar notice
requirements, however, notice of a shareholder nomination or proposal must be
received by First Source at least 90 days prior to any meeting date, except
that if less than 100 days notice of the meeting is given then such
shareholder notice or nomination must be received no later than the tenth day
following notice of the meeting.     
 
SPECIAL MEETINGS OF SHAREHOLDERS
 
  Pulse. Special meetings of shareholders of Pulse may be called by the
President, Chairman, the Board of Directors, or a committee of the board of
directors of Pulse. Shareholders are not entitled under the Pulse Certificate
to call a special meeting.
 
  First Source. Special meetings of shareholders of First Source may only be
called by resolution of the Board of Directors of First Source.
 
NUMBER AND TERM OF DIRECTORS
 
  Pulse. The Pulse Board consists of six directors. The Pulse Certificate
provides that the number of directors may be changed by the affirmative vote
of two-thirds of the then-current members of the Pulse Board. Under the Pulse
Certificate, the number of directors may not be fewer than five or more than
15. The Pulse Board is divided into three classes with two members in each
class.
 
  First Source. The First Source Board currently consists of eight directors,
and following the Merger will be expanded to 10 directors. The First Source
Certificate provides that the Board of Directors may set, by resolution, the
number of directors. The First Source Board is divided into three classes, as
equal in number as possible.
   
FILLING VACANCIES ON THE BOARD OF DIRECTORS     
 
  Pulse. The Pulse Certificate provides that any vacancy (including one
resulting from a newly created directorship) that occurs on the Pulse Board
may be filled by a majority vote of the Pulse Board and that any
 
                                      64
<PAGE>
 
director appointed to fill the vacancy will hold office for a term expiring at
the next annual meeting of shareholders.
 
  First Source. The First Source Certificate provides that any vacancy
(including one resulting from a newly created directorship) that occurs on the
First Source Board may be filled by a majority vote of the First Source Board
and any director appointed to fill the vacancy will hold office for a term
expiring at the annual meeting in which the term of the class to which such
director is appointed expires.
 
REMOVAL OF DIRECTORS
 
  Pulse. The Pulse Certificate provides that one or more directors may be
removed for cause upon the affirmative vote of the holders of at least 80% of
the outstanding shares entitled to vote generally in the election of
directors. A director may also be removed for cause by the board of directors.
 
  First Source. The First Source Certificate provides that one or more
directors may be removed for cause upon the affirmative vote of the holders of
at least 80% of the outstanding shares entitled to vote generally in the
election of directors.
 
AMENDMENT OF CERTIFICATE OF INCORPORATION AND BYLAWS
   
  Pulse. New Jersey law generally requires that an amendment to the Pulse
certificate must be approved by the Pulse board of directors and a majority of
votes cast by the holders of shares entitled to vote. The Pulse Certificate
provides that certain amendments to the Pulse Certificate must be approved by
the holders not less than 80% of the shares entitled to vote generally in the
election of directors. This 80% vote is required for amendments relating to:
(i) the number, election, classification and removal of directors; (ii)
preemptive rights; (iii) elimination of directors' liability; (iv)
indemnification of directors, officers, employees and agents; (v) meetings of
shareholders and shareholder proposals; (vi) restrictions on voting Pulse
Common Stock; (vii) approval of certain business combinations; and (viii)
amendment of the Pulse Bylaws.     
   
  The Pulse Certificate provides that the Pulse Bylaws may be amended by
either: (i) the affirmative vote of two-thirds of the directors; or (ii) the
shareholders of Pulse, by the affirmative vote of the holders of not less than
80% of the shares of Pulse entitled to vote generally in the election of
directors.     
 
  First Source. Delaware law and the First Source Certificate are
substantially similar to the provisions with respect to amendment of the Pulse
Certificate stated above.
 
  The First Source Bylaws may be amended by a majority vote of the First
Source Board.
 
PAYMENT OF DIVIDENDS
   
  The ability of First Source and Pulse to pay dividends on their common stock
is governed by Delaware and New Jersey law, respectively.     
   
  New Jersey law provides that Pulse may make distributions to its
shareholders unless, after paying the dividend: (i) Pulse would be unable to
pay its debts as they become due in the usual course of its business; or
(ii) the total assets of Pulse would be less than its total liabilities.     
   
  Delaware law provides that First Source may pay dividends only out of
either: (i) surplus, which is defined as the excess of net assets over First
Source's capital; or (ii) if no surplus, out of the net profits of First
Source for the fiscal year in which the dividend is declared or the previous
fiscal year.     
 
  The ability of First Source and Pulse to pay dividends is also affected by
regulatory restrictions on the abilities of their subsidiaries to make capital
distributions.

          UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL STATEMENTS
   
  The following tables set forth certain selected condensed financial data for
First Source and Pulse on an unaudited pro forma combined basis giving effect
to the Merger as if the Merger had become effective on June 30, 1998, in the
case of the balance sheet data presented, and if the Merger had become
effective at the beginning of the periods indicated, in the case of the income
statement data presented. The pro forma data in the tables assume that the
Merger is accounted for using the pooling of interests method of accounting.
See "THE MERGER--Anticipated Accounting Treatment." Financial data for the six
months ended June 30, 1998 and 1997 combine First Source with Pulse's interim
results presented to coincide with the reporting periods for First Source.
These tables should be read in conjunction with, and are qualified in their
entirety by, the historical financial statements, including the notes thereto,
of First Source and Pulse incorporated by reference herein, including the
notes thereto, appearing elsewhere in this Joint Proxy Statement/Prospectus.
See "INCORPORATION OF CERTAIN DOCUMENTS BY REFERENCE."     
   
  The pro forma data and ratios set forth in the following tables do not
reflect the expected cost savings and revenue enhancement opportunities that
could result from the Merger or any other items of income or expense which may
result from the Merger. The pro forma balance sheet data and certain ratios do
reflect a $4.1 million reduction, net of taxes, to retained earnings and a
corresponding increase to other liabilities at June 30, 1998. This adjustment
represents the accrual of the estimated cost of merger expenses and
restructuring charges, net of tax. The unaudited pro forma combined selected
financial data are presented for informational purposes only and is not
necessarily indicative of the combined financial position or results of
operations that would have occurred if the Merger had been consummated on June
30, 1998, or at the beginning of the periods indicated, or which may be
obtained in the future.

INTEREST OF CERTAIN PERSONS IN MATTERS TO BE ACTED UPON
 
  Upon obtaining stockholder approval, First Source and First Savings intend
to grant to non-employee directors, and selected officers and employees of
First Savings and First Source stock options and awards in the form of shares
of Common Stock under the Incentive Plan, being presented for approval in the
Proposal.
 
DIRECTORS' COMPENSATION
   
  FEE AGREEMENT. Non-employee directors of First Savings receive a monthly
retainer of $1,750, $750 for each full Board of Directors meeting attended,
and $300 for each committee meeting attended. Employee directors of First
Savings receive a monthly retainer of $1,750, but no meeting fees. Directors
currently do not receive fees for service on the First Source Board.     
 
  DIRECTORS' DEFERRED FEE PLAN. Directors may elect to defer all or part of
their fees under the Agreement for Deferment of Directors' Fees (the "Deferral
Fee Agreement"). The fees so deferred are recorded on the books of First
Savings as a liability in the year the fees are earned; however, First Savings
does not specifically fund the amount so deferred. First Savings pays the
deferred fees to the directors not earlier than the time they cease to be a
director, retirement or when they attain age 65 (or some other age
specifically elected by the director), unless First Savings determines it
serves its best interests or the best interests of the director to disburse
these funds at an earlier date.
 
  First Savings also maintains the First Savings Bank, SLA Directors' Deferred
Fee Stock Unit Plan (the "Deferred Fee Stock Unit Plan"). During First
Savings' 1992 and 1995 stock offerings and in connection with the 1998
Conversion and Reorganization of First Savings and its mutual holding company,
Directors who had deferred fees under the Deferred Fee Agreement had the
opportunity to elect to defer the fees under the Deferred Fee Stock Unit Plan.
Each Director who elected to participate in the Deferred Fee Stock Unit Plan
had his deferred fees credited with a number of shares of Common Stock based
on the fair market value of the stock. Messrs. Burke, McLaughlin, Martin,
Ruegger, Shein and Timpson currently participate in the Plan.
 
  RETIREMENT PLAN. First Savings also maintains a nonqualified, unfunded
retirement plan for directors who are not employees, have served as a director
for five (5) years, and who retire from the Board of Directors within the time
specified under the Retirement Plan. Benefits, in general, are equal either to
all or a portion of the current annual retainer received by Board members,
depending upon the director's age and length of service at retirement.
Benefits are paid monthly, commencing in the month following the director's
retirement from the Board and ending in the month following the director's
death.
   
  STOCK OPTION PLAN FOR OUTSIDE DIRECTORS. During 1992, First Savings' Board
of Directors adopted the First Savings Bank, SLA 1992 Stock Option Plan for
Outside Directors (the "Directors' Stock Option Plan") of First Savings and
its affiliates. Under the terms of the Director's Stock Option Plan, 100,399
shares of the Common Stock were reserved for issuance to directors who are not
employees of First Savings or First Source. The Directors' Stock Option Plan
is a self administering plan and provides that each member of the Board of
Directors of First Savings who is not an officer or employee of First Savings
is granted non-statutory stock options to purchase 16,733 shares of the Common
Stock (based on adjustments for four 10% stock dividends and a 2-for-1 stock
split). Upon completion of First Savings' 1998 Conversion and Reorganization,
First Source adopted the Directors' Stock Option Plan and options for First
Source Common Stock were exchanged for options in First Savings Common Stock
on a 3.9133-to-1 basis. All stock options granted under this plan are
currently exercisable at an exercise price of $.8726 per share, as adjusted
for the four 10% stock dividends, the 2-for-1 stock split and the exchange for
First Source Common Stock. As of December 31, 1997, 33,466 options had been
exercised under this plan. As of October 30, 1998, 175,962 options, as
adjusted, remain exercisable.     
 
  1996 INCENTIVE PLAN. During 1996, the Board of Directors adopted the First
Savings Bank, SLA 1996 Omnibus Incentive Plan for directors, officers and
certain employees of First Savings and its affiliates. Under the terms of the
Incentive Plan, 21,780 shares of the First Savings Common Stock were reserved
for issuance to
 
                                      75
<PAGE>
 
   
directors who are not employees of First Savings. The portion of the Incentive
Plan granting awards to directors is self administering and provides that each
member of the Board of Directors who is not an officer or employee of First
Savings or First Source is granted non-statutory options to purchase 3,630
shares of First Savings' Common Stock at an exercise price of $13.02 per
share. Stock options granted under this plan vest in equal installments over a
three-year period from the date of issuance. Upon consummation of First
Savings' 1998 Conversion and Reorganization, First Source adopted the 1996
Omnibus Incentive Plan and all shares and options awarded under the plan were
exchanged for shares and options in First Source Common Stock at the 3.9133
exchange ratio. As of October 30, 1998, 222,546 options, as adjusted, were
currently exercisable or exercisable within 60 days and 74,182 options, as
adjusted, had been granted but were not yet exercisable under the 1996
Incentive Plan.

  EXECUTIVE COMPENSATION. The following table sets forth certain information
as to the total remuneration paid by First Savings to the Chief Executive
Officer and other executive officers who received salary and bonuses in excess
of $100,000 during the year ended December 31, 1997 ("Named Executive
Officers"). In addition, the table sets forth information regarding total
remuneration for the years ended December 31, 1996 and 1995. All share
information has been adjusted to reflect a 10% stock dividend paid on October

  1996 Incentive Plan. On April 24, 1996, First Savings' stockholders approved
the First Savings Bank, SLA 1996 Omnibus Incentive Plan under which all
employees of First Savings were eligible to receive awards. The 1996 Incentive
Plan provides discretionary awards to officers and key employees, as
determined by a committee of non-employee directors. Stock options were
awarded to officers under the 1996 Incentive Plan on November 19, 1996. There
were no stock options under the Incentive Plan granted to Named Executive
Officers for the year ended December 31, 1997.
 
  The following table provides certain information with respect to the number
of shares of Common Stock acquired upon exercise of stock options and the
value realized thereon. Also reported is the number of shares of Common Stock

    issued on November 19, 1996, at an option price of $3.78 per share.
    Options granted to Messrs. Mulkerin and Martin are exercisable at the rate
    of 18,150 shares per year commencing on November 19, 1997. Options granted
    to Mr. Spengler are exercisable at the rate of 3,158 shares per year
    commencing on November 19, 1997. All options will immediately vest upon a
    change in control. The number and exercise price of options have been
    adjusted as appropriate to reflect four stock dividends, a stock split,
    and a 3.9133 exchange for options in First Source Common Stock.     
 
(2) The market value of the Common Stock at December 31, 1997, prior to the
    1998 Conversion and Reorganization, was $49.00 per share.
 
  A Committee of the Board of Directors of First Savings and First Source
comprised of non-employee directors administers the 1996 Incentive Plan, and
makes awards to executive officers pursuant to the Plan. Awards under the 1996
Incentive Plan become immediately vested in the event of death, disability,
retirement or a change in control of First Savings or its successors. Upon
consummation of First Savings' 1998 Conversion and Reorganization, First
Source adopted the 1996 Incentive Plan in its entirety, and all options and
awards for shares of First Savings Common Stock were exchanged for shares of
First Source Common Stock at the 3.9133 exchange ratio.
 
EMPLOYMENT AGREEMENTS
 
  First Savings and First Source have entered into employment agreements
(collectively, the "Employment Agreements") with Messrs. Mulkerin and Martin
(the "Executives"). The Employment Agreements are intended to ensure that
First Savings and First Source will be able to maintain a stable and competent
management base. The continued success of First Savings and First Source
depends to a significant degree on the skills and competence of Messrs.
Mulkerin and Martin.
   
  The Employment Agreements provide for a three-year term for the Executives.
First Savings' Employment Agreement provides that, commencing on the first
anniversary date and continuing each anniversary date thereafter, the Board of
Directors of First Savings and First Source will review the agreements and the
Executive's performance for purposes of determining whether to extend the
agreements with First Savings and First Source for an additional year such
that the remaining terms would be the amount of the original terms. The annual
base salary for Messrs. Mulkerin and Martin under the Employment Agreements is
$260,000 and     
 
                                      78
<PAGE>
 
$210,000, respectively. In addition to the base salary, the Employment
Agreements provide for, among other things, participation in stock benefit
plans and other fringe benefits applicable to executive personnel. The
Employment Agreements provide for termination by First Savings or First Source
for cause, as defined in the agreements, at any time. In the event First
Savings or First Source chooses to terminate the Executive's employment for
reasons other than for cause, or in the event of the Executive's resignation
from First Savings and First Source upon: (i) failure to re-elect the
Executive to his current offices; (ii) a material change in the Executive's
functions, duties or responsibilities; (iii) a relocation of the Executive's
principal place of employment by more than 25 miles; (iv) liquidation or
dissolution of First Savings or First Source; or (v) a breach of the agreement
by First Savings or First Source, the Executive or, in the event of death, his
beneficiary, is entitled to receive the remaining base salary payments due to
the Executive and the contributions that would have been made on the
Executive's behalf to any employee benefit plans of First Savings or First
Source during the remaining term of the agreement. First Savings and First
Source would also continue and pay for the Executive's life, health and
disability coverage for the remaining term of the Employment Agreements.
 
  Under the Employment Agreements, if voluntary or involuntary termination
follows a "change in control" of First Savings or First Source, as defined in
the Employment Agreements, the Executive or, in the event of death, his
beneficiary, will be entitled to a payment equal to the greater of: (1) the
payments due for the remaining term of the agreement; or (2) a severance
payment equal to three times the average of the five preceding taxable years'
compensation. First Savings and First Source would also continue the
Executive's life, health, and disability coverage for 36 months.
Notwithstanding that both agreements will provide for a severance payment in
the event of a change in control, the Executive would only be entitled to
receive a severance payment under one agreement.
   
  Payments to the Executives under First Savings' Employment Agreement are
guaranteed by First Source in the event that payments or benefits are not paid
by First Savings. Payment under First Source's Employment Agreement will be
made by First Source. All reasonable costs and legal fees paid or incurred by
the Executive pursuant to any dispute or question of interpretation relating
to the Employment Agreements will be paid by First Savings or First Source,
respectively, if the Executive is successful on the merits pursuant to a legal
judgment, arbitration or settlement. The Employment Agreements also provide
that First Savings and First Source indemnify the Executive to the fullest
extent allowable under federal and Delaware law, respectively. In the event of
a "change in control" of First Savings or First Source, the total amount of
payments that would be due under the Employment Agreements, based solely on
cash compensation paid to Messrs. Mulkerin and Martin in the past year and
excluding any benefits under any employee benefit plan which may be payable,
would be approximately $984,000 and $774,000, respectively.     
 
CHANGE IN CONTROL AGREEMENTS
   
  First Savings has also entered into Change in Control Agreements ("CIC
Agreements") with certain other officers of First Savings. Such agreements
have terms ranging from one to three years. The CIC Agreements provide that
commencing on the first anniversary date and continuing on each anniversary
thereafter, First Savings' CIC Agreements may be renewed by the Board of
Directors for an additional year. The CIC Agreements with First Savings will
also provide that in the event voluntary or involuntary termination follows a
change in control of First Savings or First Source, the officer is entitled to
receive a severance payment equal to one to three times the officer's average
annual compensation for the five years preceding termination, depending on the
term of the officers' CIC Agreement. First Source and First Savings will also
continue, and pay for, the officer's life, health and disability coverage for
12 to 36 months following termination. Payments to the officer under First
Savings' CIC Agreements will be guaranteed by First Source in the event that
payments or benefits are not paid by First Savings. In the event of a change
in control of First Savings or First Source, the total payments that would be
due under the CIC Agreements, based solely on the cash compensation paid to
the officers covered by the CIC Agreements over the past three fiscal years
and excluding any benefits under any employee benefit plan that may be
payable, would be approximately $2.2 million.

EMPLOYEE SEVERANCE COMPENSATION PLAN
 
  First Savings' Board of Directors has also established First Savings Bank,
SLA Employee Severance Compensation Plan ("Severance Plan"), which provides
eligible employees with severance pay benefits in the event of a change in
control of First Savings or First Source. Management personnel with Employment
or CIC Agreements are not eligible to participate in the Severance Plan.
Generally, all employees are eligible to participate in the Severance Plan.
Under the Severance Plan, in the event of a change in control of First Savings
or First Source, eligible employees who are terminated from or terminate their
employment within one year of the change in control (for reasons specified
under the Severance Plan), are entitled to receive a severance payment. The
participant is entitled to a cash severance payment equal to one-twelfth of
annual compensation for each year of service up to a maximum of 100% of annual
compensation. Such payments may tend to discourage takeover attempts by
increasing costs to be incurred by First Savings in the event of a takeover.
In the event the provisions of the Severance Plan were triggered, the total
amount of payments that would be due thereunder, based solely upon salary
levels at December 31, 1997, would be approximately $2.5 million.
 
BENEFIT PLANS
 
  Pension Plan. First Savings is a participant in the Financial Institutions
Retirement Fund, a multi-employer defined benefit plan. All employees age 21
or older who have completed one year of service are eligible to participate in
this Plan. Retirement benefits are based upon a formula utilizing years of
service and average compensation. Participants are vested 100% upon the
completion of five years of service.
 
  Financial Institutions Retirement Fund does not segregate its assets,
liabilities or costs by participating employer. Therefore, disclosure of the
accumulated benefit obligations, plan assets and the components of annual
pension expense attributable to First Savings cannot be ascertained.
 
  The following table illustrates annual pension benefits at age 65 under the
most advantageous plan provisions available at various levels of compensation
and years of service. The benefits listed in the table are not subject to a
deduction for Social Security or any other offset amount.

  Supplemental Executive Retirement Plan. Effective as of January 1, 1994, the
Board of Directors revised a previously existing plan entitled the Retirement
Benefit Maintenance Plan (the "Maintenance Plan") and restated it as the First
Savings Bank, SLA Supplemental Executive Retirement Plan ("SERP"). The SERP
provides a post-employment supplemental retirement benefit for participants
who retire on or after their "Normal Retirement Age" (age 65) equal to (i)
seventy-five percent (75%) of the participant's base salary during the twelve
months prior to retirement, (ii) less the amount of the participant's "Pension
Plan Annual Benefit" and "Primary Social Security Benefit," as defined in the
plan. The plan allows for benefits, reduced according to actuarial
considerations, for early retirement. The SERP is not a tax-qualified employee
benefit plan. Pursuant to the SERP, the estimated additional annual benefits
payable upon retirement at normal retirement age for Messrs. Mulkerin and
Martin are $107,600 and $47,900, respectively.
 
  First Savings also implemented in 1998 an additional supplemental executive
retirement plan to provide for supplemental benefits to certain employees
whose benefits under the ESOP and/or 401(k) Plan are reduced by limitations
imposed by the Code. From time to time, the Board will designate which
employees may participate in this additional supplemental executive retirement
plan. This supplemental executive retirement plan will also be an "unfunded"
promise to pay supplemental benefits in the future and any amount set aside to
pay the benefits under the plan remains subject to the claims of First
Savings' general creditors until they are paid to plan participants. First
Savings may establish a grantor trust in connection with the plan to satisfy
the obligations of First Savings under the plan. The grantor trust would be
permitted to invest in a wide-variety of investments, including First Source
Common Stock.
   
  Employee Stock Ownership Plan and Trust. On July 10, 1992, First Savings
established the First Savings Bank, SLA Employee Stock Ownership Plan (the
"ESOP") and related trust for eligible employees, who were employed with First
Savings as of January 1, 1992 and employees of First Source and First Savings
employed after such date, who have been credited with at least 1,000 hours
during a 12-month period and who have attained the age of 21. The ESOP
acquired 70,000 shares of common stock. On July 11, 1995, First Savings
completed a secondary offering of common stock, and the ESOP purchased 42,000
shares of common stock at $13.00 per share. Stock dividends and splits have
caused the restatement of the shares originally purchased to equal 204,974
shares and stock dividends have caused the shares purchased in the 1995
offering to equal 50,820 shares. Funds for the purchase of the additional
shares were borrowed from First Source. The ESOP acquired an additional
1,324,029 shares of Common Stock in the 1998 Conversion and Reorganization.
The funds used to acquire such shares were borrowed from First Source. The
loan was aggregated with First Source's existing loan to the ESOP and
refinanced with a 15 year payout term. The loan will be repaid principally
from First Savings' contributions to the ESOP over the 15 year term, and the
collateral for the loan is the Common Stock purchased by the ESOP.
Contributions to the ESOP will be discretionary, however, First Source or
First Savings intend to make annual contributions to the ESOP in an aggregate
amount at least equal to the principal and interest requirement on the debt.
Shares purchased by the ESOP are held by a trustee for allocation among
participants as the loan is repaid. First Savings recognizes compensation
expense when debt payments are made.     
   
  First Savings accounts for the allocation of ESOP shares purchased prior to
1995 at their original issue price. First Savings accounts for the shares
purchased in the secondary offering in accordance with American Institute of
Certified Public Accountants ("AICPA") Statement of Position ("SOP") 93-6.
Those shares had a fair value of $2.8 million at December 31, 1997. The ESOP
allocated 114,589, 114,589 and 104,172 shares for the years ended December 31,
1997, 1996 and 1995, respectively, inclusive of four stock dividends of 10%, a
2-for-1 stock split and the 3.9133 exchange ratio for shares of First Source
Common Stock. The compensation expense for payments made to the ESOP totaled
$75,000 for each of the years ended December 31, 1997, 1996 and 1995.     
       
TRANSACTIONS WITH CERTAIN RELATED PERSONS
 
  The Financial Institutions Reform, Recovery, and Enforcement Act of 1989
("FIRREA") required that all loans or extensions of credit to executive
officers and directors be made on substantially the same terms, including
interest rates and collateral, as those prevailing at the time for comparable
transactions with the general public and not involve more than the normal risk
of repayment or present other unfavorable features. In addition,
 
                                      81
<PAGE>
 
loans made to a director or executive officer in excess of the greater of
$25,000, or 5% of First Savings' capital and surplus (up to a maximum of
$500,000) must have been approved in advance by a majority of the
disinterested members of the Board of Directors.
 
  First Savings currently makes loans to its directors and executive officers
on substantially the same terms, including interest rates and collateral, as
those prevailing at the time for comparable transactions with other persons
and do not involve more than the normal risk of collectibility or present
other unfavorable features. First Savings may, in the future, determine to
offer loans to executive officers and directors on terms not available to the
public, but available to other employees, in accordance with recently modified
federal regulations. Under First Savings' existing policy, any loan to an
executive officer or director, must be approved, in advance, by a majority of
the disinterested members of the Board of Directors.
 
  Prior to the enactment of FIRREA, First Savings provided loans to directors
and executive officers at reduced rates and/or with points waived or reduced.
There were no loans to First Savings' current executive officers and directors
that exceeded $500,000 as of December 31, 1997. Set forth below is certain
information as of December 31, 1997, as to loans made by First Savings prior
to the enactment of FIRREA (August 9, 1989), to any director or executive
officer and associates of directors and executive officers whose aggregate
indebtedness to First Savings exceeded $60,000 at any time since January 1,
1997, and who were extended accommodations on origination fees and application
fees on first mortgage loans and as to rate on home equity credit lines.

approval the First Source Bancorp, Inc. 1998 Stock-Based Incentive Plan in the
form attached hereto as Annex E. The following is a summary of the material
terms of the Incentive Plan which is qualified in its entirety by the complete
provisions of the Incentive Plan attached as Annex E. For a description of
prior awards granted by First Savings, see "Executive Compensation."     
 
GENERAL
 
  The Incentive Plan authorizes the granting of options to purchase Common
Stock, option-related awards and awards of Common Stock (collectively,
"Awards"). Subject to certain adjustments to prevent dilution of Awards to
participants, the maximum number of shares reserved for Awards under the
Incentive Plan is 2,317,051 shares. All officers, other employees, Outside
Directors, and consultants and advisers of First Source and its affiliates are
eligible to receive Awards under the Incentive Plan. The Incentive Plan will
be administered by a committee of non-employee directors of First Source (the
"Committee"). Authorized but unissued shares or shares previously issued and
reacquired by First Source may be used to satisfy Awards under the Incentive
Plan. The grant of stock awards and the exercise of options granted under the
Incentive Plan will result in an increase in the number of shares outstanding,
and may have a dilutive effect on the holdings of existing shareholders.

AWARDS
 
  TYPES OF AWARDS. The Incentive Plan authorizes the grant of Awards to
officers, employees and Outside Directors in the form of: (i) options to
purchase First Source's Common Stock intended to qualify as incentive stock
options under Section 422 of the Code (options that afford tax benefits to the
recipients upon compliance with certain conditions and do not result in tax
deductions to First Source), referred to as "Incentive Stock Options"; (ii)
options that do not so qualify (options that do not afford income tax benefits
to recipients, but which may provide tax deductions to First Source), referred
to as "Non-statutory Stock Options"; (iii) limited rights that are exercisable
only upon a change in control of First Source (as defined in the Incentive
Plan) ("Limited Rights"); and (iv) Stock Awards, which provide a grant of
Common Stock that vests over time (a portion of such vesting would be
contingent upon the attainment of stated performance goals for all officers,
employees and Outside Directors who receive such Stock Awards).
 
  OPTIONS. The Incentive Plan provides for the granting of options to purchase
Common Stock of First Source ("Options") to employees, officers and Outside
Directors for up to 1,655,037 shares. Pursuant to the Incentive Plan, the
Committee has the authority to determine the date, or dates, on which Options
shall become exercisable and any other conditions which must be met prior to
becoming exercisable. The exercise price of an Option may be paid in cash or
in Common Stock at the discretion of the Committee. See "--Method of Exercise
of Options."
   
  All options granted to employees will be qualified as Incentive Stock
Options to the extent permitted under Section 422 of the Code. Incentive Stock
Options, at the discretion of the Committee with the concurrence of the
holder, may be converted into Non-Statutory Stock Options. The exercise price
of all Incentive Stock Options must be a minimum of 100% of the fair market
value of the underlying Common Stock at the time of grant, except as provided
below. In order to qualify as Incentive Stock Options under Section 422 of the
Code, the option must be granted to an employee, the exercise price must not
be less than 100% of the fair market value on the date of grant, the term of
the option may not exceed ten years from the date of grant, and no more than
$100,000 of options may become exercisable or vest in any fiscal year.
Incentive Stock Options granted to any person who is the beneficial owner of
more than 10% of the outstanding voting stock may be exercised only for a
period of five years from the date of grant and the exercise price must be at
least equal to 110% of the fair market value of the underlying Common Stock on
the date of grant.     
   
  Each Outside Director of First Source or its affiliates will be eligible to
receive Non-Statutory Stock Options to purchase shares of Common Stock.
Additionally, officers and employees are eligible to receive Non-Statutory
Stock Options under the Plan to the extent they are ineligible to receive
Incentive Stock Options. The exercise price of each Non-Statutory Stock Option
shall be equal to the greater of the fair market value of the Common Stock on
the date the option is granted or $9.00 per share.     
 
  Options granted under the Incentive Plan may be exercised at such times as
the Committee determines, but in no event shall an Option be exercisable more
than ten years from the date of grant (or five years from date of grant for a
10% owner). Unless otherwise determined by the Committee, upon termination of
an optionee's services for any reason other than death, disability, change in
control, retirement or termination for cause, all exercisable Options shall
remain exercisable for a period of three (3) months following termination and
all unexercised Options shall be canceled. Unless otherwise determined by the
Committee, in the event of the death or disability of the optionee, all
unexercisable Options held by such optionee will become fully exercisable and
remain exercisable for up to one (1) year thereafter. In the event of
termination for cause, all exercisable and unexercisable options held by the
optionee shall be canceled. In the event of the retirement of an optionee, all
exercisable options shall remain exercisable for a period of one (1) year, and
the Committee shall have the discretion to allow unexercisable options to
continue to vest in accordance with their original terms, provided the
optionee is immediately engaged as a consultant, advisor or advisory director
of First Source or any of its affiliates. Any option originally designated as
an Incentive Stock Option shall be treated as a Non-statutory Stock Option to
the extent the optionee exercises such option more than three (3) months after
retirement. In the event of the termination of an optionee due to a change in
control of First Source or First Savings, the optionee may
 
                                      83
<PAGE>
 
exercise only those options that were exercisable upon termination and only
for a period of one (1) year with respect to Non-Statutory Stock Options and
three (3) months with respect to Incentive Stock Options.
 
  LIMITED RIGHTS. The Incentive Plan also provides the Committee with the
ability to grant a Limited Right concurrently with any Option. Limited Rights
are related to specific Options granted and become exercisable only upon a
change in control of First Savings or First Source. Upon exercise, the holder
will be entitled to receive in lieu of purchasing the stock underlying the
Option, a lump sum cash payment equal to the difference between the exercise
price of the related Option and the fair market value of the shares of Common
Stock subject to the Option on the date of exercise of the right less any
applicable tax withholding.
 
  STOCK AWARDS. The Incentive Plan also authorizes the granting of Stock
Awards to employees and Outside Directors, in an amount not to exceed 662,014
shares in the aggregate. The Committee has the authority to determine the
dates on which Stock Awards granted will vest or any other conditions that
must be satisfied prior to vesting.
 
  When stock awards are distributed in accordance with the Incentive Plan, the
recipients will also receive amounts equal to accumulated cash and stock
dividends (if any) with respect thereto plus earnings thereon minus any
required tax withholding amounts. Prior to vesting, recipients of Awards may
direct the voting of shares of Common Stock granted to them and held in a
trust established to hold shares of Common Stock which may be granted under
the Incentive Plan. Shares of Common Stock held by the Incentive Plan trust
which have not been allocated or for which voting has not been directed are
voted by the trustee in the same proportion as the awarded shares are voted in
accordance with the directions given by all recipients of Awards.
 
  Unless otherwise determined by the Committee, upon termination of the
services of a holder of a Stock Award for any reason other than death,
disability, change in control, retirement or termination for cause, all such
holder's rights in unvested Stock Awards shall be canceled. Unless otherwise
determined by the Committee, in the event of the death or disability of the
holder of the Stock Award, all unvested Stock Awards held by such individual
will become fully vested. In the event of the termination of a holder of a
Stock Award due to a change in control of First Source or First Savings, or
termination for cause of a holder of a Stock Award, all unvested Stock Awards
held by such individual shall be canceled. In the event of a Stock Award
holder's retirement, the Committee shall have the discretion to determine that
all unvested Stock Awards shall continue to vest in accordance with their
original terms, provided the holder is engaged as a consultant, advisor or
advisory director of First Source or any of its affiliates.
 
TAX TREATMENT
 
  OPTIONS. An optionee will generally not be deemed to have recognized taxable
income upon grant or exercise of any Incentive Stock Option, provided that
shares transferred in connection with the exercise are not disposed of by the
optionee for at least one year after the date the shares are transferred in
connection with the exercise of the option and two years after the date of
grant of the option. If certain holding periods are satisfied, upon disposal
of the shares, the aggregate difference between the per share option exercise
price and the fair market value of the Common Stock is recognized as income
taxable at long-term capital gains rates. No compensation deduction may be
taken by First Source as a result of the grant or exercise of Incentive Stock
Options, assuming these holding periods are met.
 
  In the case of the exercise of a Non-Statutory Stock Option, an optionee
will be deemed to have received ordinary income upon exercise of the stock
option in an amount equal to the aggregate amount by which the per share
exercise price is exceeded by the fair market value of the Common Stock. In
the event shares received through the exercise of an Incentive Stock Option
are disposed of prior to the satisfaction of the holding periods (a
"disqualifying disposition"), the exercise of the option will be treated as
the exercise of a Non-Statutory Stock Option, except that the optionee will
recognize the ordinary income for the year in which the disqualifying
disposition occurs. The amount of any ordinary income deemed to have been
received by an optionee upon the exercise of a Non-Statutory Stock Option or
due to a disqualifying disposition will be a deductible expense of First
Source for tax purposes.
 
                                      84
<PAGE>
 
  LIMITED RIGHTS. In the case of Limited Rights, the holder would have to
include the amount paid to him upon the exercise of the Limited Right in his
gross income for federal income tax purposes in the year in which the payment
is made and First Source would be entitled to a deduction for federal income
tax purposes of the amount paid.
 
  STOCK AWARDS. When shares of Common Stock, as Stock Awards, are distributed,
the recipient is deemed to receive ordinary income equal to the fair market
value of such shares at the date of distribution plus any dividends and
earnings on such shares (provided such date is more than six months after the
date of grant) and First Source is permitted a commensurate compensation
expense deduction for income tax purposes.
 
PERFORMANCE AWARDS
 
  GENERAL. The Incentive Plan provides the Committee with the ability to
condition or restrict the vesting or exercisability of any Award upon the
achievement of performance targets or goals as set forth under the Incentive
Plan. Any Award subject to such conditions or restrictions is considered to be
a "Performance Award." Subject to the express provisions of the Plan and as
discussed in this paragraph, the Committee has discretion to determine the
terms of any Performance Award, including the amount of the award, or a
formula for determining such, the performance criteria and level of
achievement related to these criteria which determine the amount of the award
granted, issued, retainable and/or vested, the period as to which performance
shall be measured for determining achievement of performance (a "performance
period"), the timing of delivery of any awards earned, forfeiture provisions,
the effect of termination of employment for various reasons, and such further
terms and conditions, in each case not inconsistent with the Plan, as may be
determined from time to time by the Committee. The performance criteria upon
which Performance Awards are granted, issued, retained and/or vested may be
based on financial performance and/or personal performance evaluations, except
that for any Performance Award that is intended by the Committee to satisfy
the requirements for "performance-based compensation" under Code Section
162(m), the performance criteria shall be a measure based on one or more
Qualifying Performance Criteria (as defined below). Notwithstanding
satisfaction of any performance goals, the number of shares granted, issued,
retainable and/or vested under a Performance Award may be adjusted by the
Committee on the basis of such further considerations as the Committee in its
sole discretion shall determine. However, the Committee may not increase the
amount earned upon satisfaction of any performance goal by any Participant who
is a "covered employee" within the meaning of Section 162(m) of the Code.
 
  QUALIFYING PERFORMANCE CRITERIA AND SECTION 162(M) LIMITS. Subject to
stockholder approval of the Plan, the performance criteria for any Performance
Award that is intended to satisfy the requirements for "performance-based
compensation" under the Code Section 162(m) shall be based upon any one or
more of the following performance criteria, either individually, alternatively
or in any combination, applied to either First Source as a whole or to a
business unit or subsidiary, either individually, alternatively or in any
combination, and measured either on an absolute basis or relative to a pre-
established target, to previous years' results or to a designated comparison
group, in each case as pre-established by the Committee under the terms of the
Award; net income, as adjusted for non-recurring items; cash earnings;
earnings per share; cash earnings per share; return on equity; return on
assets; assets; stock price; total shareholder return; capital; net interest
income; market share; cost control or efficiency ratio; and asset growth.
 
  The aggregate amount of Options granted under the Plan during any 60-month
period to any one Participant may not exceed 25% of the total amount of
options available to be granted under the Incentive Plan. The aggregate amount
of shares of Common Stock issuable under a Stock Award granted under the Plan
for any 60-month period to any one Participant may not exceed 25% of the total
amount of Stock Awards available to be granted under the Incentive Plan.
 
  PAYOUT OF AWARDS. Payment due to a participant upon the exercise of an
option or the redemption of a Stock Award shall be in the form of shares of
Common Stock. Payment upon the exercise of a Limited Right shall be made in
cash. Any shares of Common Stock tendered in payment of an obligation arising
under the Incentive Plan or applied to tax withholding amounts shall be valued
at the fair market value of the Common
 
                                      85
<PAGE>
 
Stock. The Committee may use treasury stock, authorized but unissued stock or
it may direct the market purchase of shares of Common Stock to satisfy its
obligations under the Incentive Plan.
 
METHOD OF EXERCISE OF OPTIONS
 
  Subject to the terms of the Incentive Plan, the Committee has discretion to
determine the form of payment for the exercise of an Option. The Committee may
indicate acceptable forms in the Award Agreement covering such Options or may
reserve its decision to the time of exercise. No Option is to be considered
exercised until payment in full is accepted by the Committee. The Committee
may permit the following forms of payment for Options: (a) in cash or by
certified or cashiers check, or (b) by tendering previously acquired shares of
Common Stock. Any shares of Common Stock tendered in payment of the exercise
price of an Option shall be valued at the Fair Market Value of the Common
Stock on the due date prior to the date of exercise.
 
AMENDMENT
 
  The Board of Directors may amend the Incentive Plan in any respect, at any
time, provided that no amendment may affect the rights of the holder of an
Award without his or her permission. In addition, no amendment may adversely
affect the rights of an Award recipient without his or her permission.
 
ADJUSTMENTS
 
  In the event of any change in the outstanding shares of Common Stock of
First Source by reason of any stock dividend or split, recapitalization,
merger, consolidation, spin-off, reorganization, combination or exchange of
shares, or other similar corporate change, or other increase or decrease in
such shares without receipt or payment of consideration by First Source, or in
the event an extraordinary capital distribution is made, including the payment
of an extraordinary dividend, the Committee may make such adjustments to
previously granted Awards, to prevent dilution, diminution or enlargement of
the rights of the holder. All Awards under this Incentive Plan shall be
binding upon any successors or assigns of First Source.
 
NONTRANSFERABILITY
 
  Unless determined otherwise by the Committee, awards under the Incentive
Plan shall not be transferable by the recipient other than by will or the laws
of intestate succession or pursuant to a domestic relations order. With the
consent of the Committee, a participant may designate a person or his or her
estate as beneficiary of any award to which the recipient would then be
entitled, in the event of the death of the participant.
 
SHAREHOLDER APPROVAL
   
  The Incentive Plan complies with the regulations of the OTS. The OTS has not
endorsed or approved the Incentive Plan. Pursuant to OTS regulations, the
Incentive Plan may not be implemented during the first year after First
Savings' 1998 Conversion and Reorganization unless the affirmative vote of the
holders of a majority of the total votes eligible to be cast at this Special
Meeting is received. If such approval is not obtained, but the Incentive Plan
receives the affirmative vote of a majority of the shares present at the
Special Meeting and eligible to be cast on the Proposal, the Incentive Plan
will not become effective at this time, but will become effective immediately
following a period of one year after the 1998 Conversion and Reorganization
without further shareholder approval. The Board of Directors also could
determine to have the Incentive Plan become effective one year after the 1998
Conversion and Reorganization even if the Incentive Plan does not receive the
requisite affirmative vote of shareholders at this Special Meeting. In the
absence of shareholder approval, the option awards under the Incentive Plan
would not qualify as Incentive Stock Options under the Code, and First
Source's qualification to have its stock traded on the Nasdaq National Market
could be adversely affected.     
 
  UNLESS MARKED TO THE CONTRARY, THE SHARES REPRESENTED BY THE ENCLOSED PROXY
CARD, IF EXECUTED AND RETURNED, WILL BE VOTED "FOR" THE APPROVAL OF THE FIRST
SOURCE BANCORP, INC. 1998 STOCK-BASED INCENTIVE PLAN.
 
  THE BOARD OF DIRECTORS RECOMMENDS THAT YOU VOTE "FOR" THE APPROVAL OF THE
FIRST SOURCE BANCORP, INC. 1998 STOCK-BASED INCENTIVE PLAN.

NEW PLAN BENEFITS
 
  The following table provides certain information with respect to all Awards
that are intended to be granted immediately after the Special Meeting,
assuming stockholder approval is obtained, under the Incentive Plan,
specifying the amounts to be granted to the named executive officers
individually, all current executive officers as a group, all current directors
who are not executive officers as a group, and all employees, including all
current officers who are not executive officers, as a group.
 
  All awards granted to the officers and directors of First Source and First
Savings reflected in the table below become vested and exercisable in equal
annual installments of 20% each year commencing one year from the date of
grant. All such awards will immediately vest and become exercisable upon
termination of employment due to death or disability. Additionally, on or
after April 8, 1999, the Board of Directors intends to amend the Incentive
Plan or the awards reflected below to provide for acceleration of the vesting
of such previously granted awards upon a change in control of First Source or
First Savings (as defined in the Incentive Plan). The Incentive Plan generally
defines a change in control to occur when a person or group of persons acting
in concert acquires beneficial ownership of 20% or more of any class of equity
security, such as the Common Stock of First Source or First Savings, or in the
event of a tender offer or exchange offer, merger or other form of business
combination, sale of assets or contested election of directors which results
in a change in control of a majority of the incumbent Board of Directors of
First Source or First Savings. First Source will present any such amendment
made more than one year after the 1998 Conversion and Reorganization to
stockholders for approval, if required by the OTS. First Source is not
otherwise required to obtain stockholder approval of amendments to the
Incentive Plan.

            AMENDMENT OF FIRST SOURCE CERTIFICATE OF INCORPORATION
   
  The Board of Directors of First Source has proposed that the Company's
Certificate of Incorporation be amended to change the name of the Company from
First Source Bancorp, Inc. to First Sentinel Bancorp, Inc. A copy of the
Corporate Name Amendment is attached at Annex F and incorporated herein by
reference.     
   
  The Corporate Name Amendment, if passed, would become effective upon the
filing with the Secretary of State of Delaware a Certificate of Amendment,
which filing is expected to take place shortly after the shareholders approve
the amendment. The affirmative vote of the holders of a majority of the
outstanding shares of Common Stock entitled to vote on the Amendment is
required to approve the Corporate Name Amendment.     
 
  The Board of Directors believe that a name change would be beneficial to the
Company because it allows for a diversity of operations which is consistent
with the future plans of the Company.
 
  UNLESS MARKED TO THE CONTRARY, THE SHARES REPRESENTED BY THE ENCLOSED PROXY
CARD, IF EXECUTED AND RETURNED, WILL BE VOTED "FOR" THE APPROVAL OF THE
CORPORATE NAME AMENDMENT.
 
  THE BOARD OF DIRECTORS RECOMMENDS THAT YOU VOTE "FOR" THE APPROVAL OF THE
CORPORATE NAME AMENDMENT.

"Effective Time" shall be the date and time when the Merger becomes effective,
as set forth in the Certificate of Merger.

     1.3   Effects of the Merger.  At and after the Effective Time, the Merger
           ---------------------                                              
shall have the effects set forth in Sections 259 and 261 of the DGCL and Section
14A:10-6 of NJBCA.

     1.4   Conversion of Company Common Stock.
           ---------------------------------- 

           (a) At the Effective Time, subject to Section 2.2 (e) hereof, each
share of the common stock, par value $1.00 per share, of the Company (the
"Company Common Stock") issued and outstanding immediately prior to the
Effective Time (other than shares of Company Common Stock held (x) in the
Company's treasury or (y) directly or indirectly by Buyer or the Company or any
of their respective Subsidiaries (as defined below) (except for Trust Account
Shares and DPC shares, as such terms are defined in Section 1.4 (b) hereof))
shall, by virtue of this Agreement and without any action on the part of the
holder thereof, be converted into and exchangeable for the number of shares (the
"Exchange Ratio") of the common stock, par value $0.01 per share, of Buyer
("Buyer Common Stock"), determined as follows (I) subject to the provisions of
Section 8.1(h), if the Average Closing Price (as defined below) is equal to or
greater than $11.50, the Exchange Ratio shall be equal to 3.2 (the "Minimum
Exchange Ratio"); (II) if the Average Closing Price is $10.00 or greater but
less than $11.50, the Exchange Ratio shall be 3.2; (III) if the Average Closing
Price is greater than $8.50 but less than $10.00 the Exchange Ratio shall equal
$32.00 divided by the Average Closing Price; or (IV) subject to the provisions
of Section 8.1(g) hereof, if the Average Closing Price is equal to or less than
$8.50, the Exchange Ratio shall be 3.764 (the "Maximum Exchange Ratio"). As used
herein, the term "Average Closing Price" means the average of the last reported
daily sales price (or if no sale on such date, then the mean of the closing
bid/ask price) per share of Buyer Common Stock on the Nasdaq Stock Market
("Nasdaq"), for the 10 consecutive trading days (the "Valuation Period") ending
on the fifth business day prior to the later of approval of the Buyer's
stockholders, approval of the Company's stockholders or the date on which the
last of all regulatory approvals required to consummate the transactions
contemplated hereby (including the Merger and the Subsidiary Merger) are
obtained, without regard to any requisite waiting periods in respect thereof.
All of the shares of Company Common Stock converted into Buyer Common Stock
pursuant to this Article I shall no longer be outstanding and shall
automatically be cancelled and shall cease to exist, and each certificate (each
a "Certificate") previously representing any such shares of Company Common Stock
shall thereafter only represent the right to receive (i) the number of whole
shares of Buyer Common Stock and (ii) the cash in lieu of fractional shares into
which the shares of Company Common Stock represented by such Certificate have
been converted pursuant to this Section 1.4(a) and Section 2.2(e) hereof.
Certificates previously representing shares of Company Common Stock shall be
exchanged for certificates representing whole shares of Buyer Common Stock and
cash in lieu of fractional shares issued in consideration therefor upon the
surrender of such Certificates in accordance with Section 2.2 hereof, without
any interest thereon. If prior to the Effective Time Buyer should split or
combine

                                      -2-
<PAGE>
 
its common stock, or pay a dividend or other distribution in such common stock,
then the Exchange Ratio, Minimum Exchange Ratio and Maximum Exchange Ratio shall
be appropriately adjusted to reflect such split, combination, dividend or
distribution.

          (b) At the Effective Time, all shares of Company Common Stock that 
are owned by the Company as treasury stock and all shares of Company Common
Stock that are owned directly or indirectly by Buyer or the Company or any of
their respective Subsidiaries (other than shares of Company Common Stock (x)
held directly or indirectly in trust accounts, managed accounts and the like or
otherwise held in a fiduciary capacity that are beneficially owned by third
parties (any such shares, and shares of Buyer Common Stock which are similarly
held, whether held directly or indirectly by Buyer or the Company, as the case
may be, being referred to herein as "Trust Account Shares") and (y) shares of
Company Common Stock held by Buyer or the Company or any of their respective
Subsidiaries in respect of a debt previously contracted (any such shares of
Company Common Stock, and shares of Buyer Common Stock which are similarly held,
whether held directly or indirectly by Buyer or the Company being referred to
herein as "DPC Shares")) shall be cancelled and shall cease to exist and no
stock of Buyer or other consideration shall be delivered in exchange therefor.
All shares of Buyer Common Stock that are owned by the Company or any of its
Subsidiaries (other than Trust Account Shares and DPC Shares) shall become
treasury stock of Buyer.

     1.5   Stock Options.
           ------------- 

           (a) At the Effective Time, all options granted by the Company
("Company Options") to purchase shares of Company Common Stock which are
outstanding and unexercised immediately prior thereto shall, at the Company's
election to be made by written notice to the Buyer within 30 days of the date
hereof, be converted, in their entirety, automatically into either options to
purchase shares of Buyer Common Stock in an amount and at an exercise price
determined as provided below (and otherwise subject to the terms of the
Company's 1986 and 1993 Stock Option and Incentive Plans and the Company's 1997
Directors Stock Option Plan and 1997 Stock Compensation Plan (collectively, the
"Company's Stock Plans")) or shares of Buyer Common Stock in an amount and at an
exercise price determined as provided below, provided, however, that such
conversion does not impair the pooling of interests accounting treatment:

          (1) The number of shares of Buyer Common Stock to be subject to the
     new options or to the exchange for Company Options shall be equal to the
     product of the number of shares of Company Common Stock subject to the
     original options and the Exchange Ratio, provided that any fractional
     shares of Buyer Common Stock resulting from such multiplication shall be
     rounded down to the nearest share; and

          (2) The exercise price per share of the Company Options if exchanged
     for shares of Buyer Common Stock, or of Buyer Common Stock under the new
     options if exchanged for options for Buyer Common Stock shall be equal to
     the exercise price per share of Company Common Stock under the original
     option divided by the Exchange Ratio, provided that such exercise price
     shall be rounded up to the nearest cent.

                                      -3-

The adjustment provided herein with respect to any options which are "incentive
stock options" (as defined in Section 422 of the Internal Revenue Code of 1986,
as amended (the "Code")) shall be and is intended to be effected in a manner
which is consistent with Section 424(a) of the Code.  The duration and other
terms of the new option shall be the same as the original option, except that
all references to the Company shall be deemed to be references to Buyer.

          (b) Shares of Buyer Common Stock issuable upon exercise of Company
Stock Options shall be covered by an effective registration statement on Form S-
8, and Buyer shall file a registration statement on Form S-8 covering such
shares as soon as practicable after the Effective Time, but in no event later
than 30 days after the Effective Time.

          (c) It is understood that the holders of a Company Option may
exercise such options, in accordance with the terms of the option, and
applicable regulations, prior to the Effective Time.

     1.6  Buyer Common Stock.  Except for shares of Buyer Common Stock owned by
          ------------------                                                   
the Company or any of its Subsidiaries (other than Trust Account Shares and DPC
Shares), which shall be converted into treasury stock of Buyer as contemplated
by Section 1.4 hereof, the shares of Buyer Common Stock issued and outstanding
immediately prior to the Effective Time shall be unaffected by the Merger and at
the Effective Time, such shares shall remain issued and outstanding.

     1.7  Certificate of Incorporation.  At the Effective Time, the Certificate
          ----------------------------

          -------                                                            
immediately prior to the Effective Time, shall be the By-Laws of the Surviving
Corporation until thereafter amended in accordance with applicable law, subject
to amendment to increase the number of director seats by two.

     1.9  Directors and Officers.  Except as provided in Section 6.14 hereof,
          ----------------------

office in accordance with the Certificate of Incorporation and By-Laws of the
Surviving Corporation until their respective successors are duly elected or

                                  ARTICLE II

                              EXCHANGE OF SHARES

     2.1  Buyer to Make Shares Available.  At or prior to the Effective Time,
          ------------------------------                                     
Buyer shall deposit, or shall cause to be deposited, with a bank or trust
company (which may be a Subsidiary of Buyer) (the "Exchange Agent"), selected by
Buyer and reasonably satisfactory to the Company, for the benefit of the holders
of Certificates, for exchange in accordance with this Article II, certificates
representing the shares of Buyer Common Stock and the cash in lieu of fractional
shares (such cash and certificates for shares of Buyer Common Stock, together
with any dividends or distributions with respect thereto, being hereinafter
referred to as the "Exchange Fund") to be issued pursuant to Section 1.4 and
paid pursuant to Section 2.2(a) in exchange for outstanding shares of Company
Common Stock.

     2.2  Exchange of Shares.
          ------------------

          (a) As soon as practicable after the Effective Time, and in no event
more than three business days thereafter, the Exchange Agent shall mail to each
holder of record of a Certificate or Certificates a form letter of transmittal
(which shall specify that delivery shall be effected, and risk of loss and title
to the Certificates shall pass, only upon delivery of the Certificates to the
Exchange Agent) and instructions for use in effecting the surrender of the
Certificates in exchange for certificates representing the shares of Buyer
Common Stock and the cash in lieu of fractional shares into which the shares of
Company Common Stock represented by such Certificate or Certificates shall have
been converted pursuant to this Agreement. The Company shall have the right to
review both the letter of transmittal and the instructions prior to the
Effective Time and provide reasonable comments thereon. Upon surrender of a
Certificate for exchange and cancellation to the Exchange Agent, together with
such letter of transmittal, duly executed, the holder of such Certificate shall
be entitled to receive in exchange therefor (x) a certificate representing that
number of whole shares of Buyer Common Stock to which such holder of Company
Common Stock shall have become entitled pursuant to the provisions of Article I
hereof and (y) a check representing the amount of cash in lieu of fractional
shares, if any, which such holder has the right to receive in respect of the
Certificate surrendered pursuant to the provisions of this Article II, and the
Certificate so surrendered shall forthwith be cancelled. No interest will be
paid or accrued on the cash in lieu of fractional shares and unpaid dividends
and distributions, if any, payable to holders of Certificates.

          (b) No dividends or other distributions declared after the Effective
Time with respect to Buyer Common Stock and payable to the holders of record
thereof shall be paid to the holder of any unsurrendered Certificate until the
holder thereof shall surrender such Certificate in accordance with this Article
II. After the surrender of a Certificate in accordance with this Article II, the
record holder thereof shall be entitled to receive any such dividends or other
distributions, without any interest thereon, which theretofore had become
payable with respect to shares of Buyer Common Stock represented by such
Certificate. No holder of an unsurrendered Certificate shall be entitled, until
the surrender of such Certificate, to vote the shares of Buyer Common Stock into
which his Company Common Stock shall have been converted.

                                      -5-
<PAGE>
 
          (c) If any certificate representing shares of Buyer Common Stock is to
be issued in a name other than that in which the Certificate surrendered in
exchange therefor is registered, it shall be a condition of the issuance thereof
that the Certificate so surrendered shall be properly endorsed (or accompanied
by an appropriate instrument of transfer) and otherwise in proper form for
transfer, and that the person requesting such exchange shall pay to the Exchange
Agent in advance any transfer or other taxes required by reason of the issuance
of a certificate representing shares of Buyer Common Stock in any name other
than that of the registered holder of the Certificate surrendered, or required
for any other reason, or shall establish to the satisfaction of the Exchange
Agent that such tax has been paid or is not payable.

          (d) After the Effective Time, there shall be no transfers on the stock
transfer books of the Company of the shares of Company Common Stock which were
issued and outstanding immediately prior to the Effective Time.  If, after the
Effective Time, Certificates representing such shares are presented for transfer
to the Exchange Agent, they shall be cancelled and exchanged for certificates
representing shares of Buyer Common Stock as provided in this Article II.

          (e) Notwithstanding anything to the contrary contained herein, no
certificates or scrip representing fractional shares of Buyer Common Stock shall
be issued upon the surrender for exchange of Certificates, no dividend or
distribution with respect to Buyer Common Stock shall be payable on or with
respect to any fractional share, and such fractional share interests shall not
entitle the owner thereof to vote or to any other rights of a shareholder of
Buyer.  In lieu of the issuance of any such fractional share, Buyer shall pay to
each former stockholder of the Company who otherwise would be entitled to
receive a fractional share of Buyer Common Stock an amount in cash determined by
multiplying (i) the product of the Average Closing Price and the Exchange Ratio
by (ii) the fraction of a share of Buyer Common Stock to which such holder would
otherwise be entitled to receive pursuant to Section 1.4 hereof.

          (f) Any portion of the Exchange Fund that remains unclaimed by the
stockholders of the Company for six months after the Effective Time shall be
paid to Buyer.  Any stockholders of the Company who have not theretofore
complied with this Article II shall thereafter look only to Buyer for payment of
their shares of Buyer Common Stock, cash in lieu of fractional shares and unpaid
dividends and distributions on the Buyer Common Stock deliverable in respect of
each share of Company Common Stock such stockholder holds as determined pursuant
to this Agreement, in each case, without any interest thereon.  Notwithstanding
the foregoing, none of Buyer, the Company, the Exchange Agent or any other
person shall be liable to any former holder of shares of Company Common Stock
for any amount properly delivered to a public official pursuant to applicable
abandoned property, escheat or similar laws.

          (g) In the event any Certificate shall have been lost, stolen or
destroyed, upon the making of an affidavit of that fact by the person claiming
such Certificate to be lost, stolen or destroyed and the posting by such person
of a bond in such amount as Buyer may direct as indemnity against any claim that
may be made against it with respect to such Certificate, the Exchange Agent will
issue in exchange for such lost, stolen or destroyed Certificate the shares of

                                      -6-
<PAGE>
 
Buyer Common Stock and cash in lieu of fractional shares deliverable in respect
thereof pursuant to this Agreement.

                 REPRESENTATIONS AND WARRANTIES OF THE COMPANY

     The Company hereby represents and warrants to Buyer as follows:

     3.1  Corporate Organization.
          ---------------------- 

          (a) The Company is a corporation duly organized, validly existing and
in good standing under the laws of the State of New Jersey. The Company 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 (as defined below) on the Company. The Company is duly
registered as a unitary savings and loan holding company under the Home Owners'
Loan Act of 1933, as amended. The Certificate of Incorporation and By-laws of
the Company, copies of which have previously been delivered to Buyer, are true,
complete and correct copies of such documents as in effect as of the date of
this Agreement. As used in this Agreement, the term "Material Adverse Effect"
means, with respect to Buyer, the Company or the Surviving Corporation, as the
case may be, a material adverse effect on the business, properties, assets,
liabilities, results of operations or financial condition of such party and its
Subsidiaries taken as a whole, other than any such effect attributable to or
resulting from general economic conditions. As used in this Agreement, the word
"Subsidiary" when used with respect to any party means any corporation,
partnership or other organization, whether incorporated or unincorporated, which
is consolidated with such party for financial reporting purposes.

          (b) The Company Bank is a savings bank duly organized, validly
existing and in good standing under the laws of the State of New Jersey. The
deposit accounts of the Company Bank are insured by the Federal Deposit
Insurance Corporation (the "FDIC") through the Savings Association Insurance
Fund to the fullest extent permitted by law, and all premiums and assessments
required to be paid in connection therewith have been paid when due by the
Company Bank. Each of the Company's other Subsidiaries is a corporation duly
organized, validly existing and in good standing under the laws of its
jurisdiction of incorporation or organization. Each of the Company's
Subsidiaries 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 the 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 Company. The articles of
incorporation, by-laws and similar governing documents of each Subsidiary of the
Company,
                                      -7-
<PAGE>
 
copies of which have previously been delivered to Buyer, are true, complete and
correct copies of such documents as in effect as of the date of this Agreement.

          (c) The minute books of the Company and each of its Subsidiaries
contain true, complete and accurate records in all material respects of all

the option issued to Buyer pursuant to the Stock Option Agreement, dated July 9,
1998, between Buyer and the Company (the "Option Agreement") and (z) no shares
of Company Preferred Stock issued or outstanding, held in the Company's treasury
or reserved for issuance upon exercise of outstanding stock options or
otherwise. All of the issued and outstanding shares of Company Common Stock have
been duly authorized and validly issued and are fully paid, nonassessable and
free of preemptive rights. Except as referred to above or reflected in Section
3.2(a) of the Company Disclosure Schedule, and except for the Option Agreement,
the Company does not have and is not bound by any outstanding subscriptions,
options, warrants, calls, commitments or agreements of any character calling for

Option Plan, the Incentive Plan, as applicable, are set forth in Section 3.2(a)
of the Company Disclosure Schedule.

          (b) Section 3.2(b) of the Company Disclosure Schedule sets forth a
true and correct list of all of the Subsidiaries of the Company as of the date

and clear of all liens, charges, encumbrances and security interests whatsoever,
and all of such shares are duly authorized and validly issued and are fully
paid, nonassessable and free of preemptive rights. No Subsidiary of the Company
has or is bound by any outstanding subscriptions, options, warrants, calls,
commitments or agreements of any character calling for

or otherwise receive any shares of capital stock or any other equity security of
such Subsidiary. Assuming compliance by Buyer with Section 1.5 hereof, at the
Effective Time, there will not be any outstanding subscriptions, options,
warrants, calls, commitments or agreements of any character by which the Company
or any of its Subsidiaries will be bound calling for the purchase or issuance of

necessary to consummate the transactions contemplated thereby. The Bank Merger
Agreement, upon execution and delivery by the Company Bank, will be duly and

its Reports for periods ending after September 30, 1997 have been and will be,
adequate in all material respects, as of the dates thereof, under generally
accepted accounting principles, and no Regulatory Agencies have required or
requested Company to increase the allowance for loan losses for such periods.

          (b) Except as set forth in Section 3.27 of the Company Disclosure
Schedule, neither the Company nor any of its Subsidiaries is a party to any
written or oral (i) loan agreement, note or borrowing arrangement (including,
without limitation, leases, credit enhancements, commitments, guarantees and

obligor is, as of the date of this Agreement, over 90 days delinquent in payment

any director, executive officer or ten percent stockholder of the Company or any
of its Subsidiaries, or to the best knowledge of the Company, any person,
corporation or enterprise controlling, controlled by or under common control

          (c) To the best of its knowledge, each loan reflected as an asset
 in the Company Disclosure Schedule (i) is evidenced by notes, agreements or
other evidences of indebtedness which are true, genuine and correct in all
material respects, (ii) to the extent secured, has been secured by valid liens
and security interests which have been perfected, and (iii) is the legal, valid
and binding obligation of the obligor named therein, enforceable in accordance
with its terms, subject to bankruptcy, insolvency, fraudulent conveyance and
other laws of general applicability relating to or affecting creditors' rights
and to general equity principles, in each case other than loans as to which the
failure to satisfy the foregoing standards would not have a Material Adverse
Effect on the Company.

record keeping issues raised in order for the data processing systems used in
the business conducted by the Company and its Subsidiaries to be substantially
Year 2000 compliant on or before the end of 1999 and, except as set forth in the

addressing such issues to be material.  Neither the Company nor any of its
Subsidiaries has received a rating of less than satisfactory from any bank
regulatory agency with respect to Year 2000 compliance.

connection with any such action.

          (b) The parties hereto shall cooperate with each other and use their
best efforts to promptly prepare and file all necessary documentation, to effect
all applications, notices, petitions and filings, and to obtain as promptly as
practicable all permits, consents, approvals and authorizations of all third
parties and Governmental Entities which are necessary or advisable to consummate
the transactions contemplated by this Agreement (including without limitation
the Merger and the Subsidiary Merger) (it being understood that any amendments
to the S-4 or a resolicitation of proxies as consequence of a subsequent
proposed merger, stock purchase or similar acquisition by Buyer or any of its
Subsidiaries shall not violate this covenant). The Company and Buyer shall have
the right to review in advance, and to the extent practicable each will consult
the other on, in each case subject to applicable laws relating to the exchange
of

                                      -36-
<PAGE>
 
information, all the information relating to the Company or Buyer, as the
case may be, and any of their respective Subsidiaries, which appear in any
filing made with, or written materials submitted to, any third party or any
Governmental Entity in connection with the transactions contemplated by this
Agreement.  In exercising the foregoing right, each of the parties hereto shall
act reasonably and as promptly as practicable.  The parties hereto agree that

matters relating to completion of the transactions contemplated herein.

          (c) Buyer and the Company shall, upon request, furnish each other with
all information concerning themselves, their Subsidiaries, directors, officers
and stockholders and such other matters as may be reasonably necessary or
advisable in connection with the Proxy Statement, the S-4 or any other
statement, filing, notice or application made by or on behalf of Buyer, the
Company or any of their respective Subsidiaries to any Governmental Entity in
connection with the Merger and the other transactions contemplated by this
Agreement.

          (d) Buyer and the Company shall promptly furnish each other with

date of this Agreement) from, or delivered by any of the foregoing to, any
Governmental Entity in respect of the transactions contemplated hereby.

     6.2  Access to Information.
          --------------------- 

          (a) Upon reasonable notice and subject to applicable laws relating to
the exchange of information, the Company shall, and shall cause each of its
Subsidiaries to, afford to the officers, employees, accountants, counsel and
other representatives of Buyer, access, during normal business hours during the
period prior to the Effective Time, to all its properties, books, contracts,
commitments, records, officers, employees, accountants, counsel and other
representatives and, during such period, the Company shall, and shall cause its
Subsidiaries to, make available to Buyer (i) a copy of each report, schedule,
registration statement and other document filed or received by it during such
period pursuant to the requirements of Federal securities laws or Federal or
state banking laws (other than reports or documents which the Company is not
permitted to disclose under applicable law) and (ii) all other information
concerning its business, properties and personnel as Buyer may reasonably
request. Neither the Company nor any of its Subsidiaries shall be required to
provide access to or to disclose information where such access or disclosure
would violate or prejudice the rights of the Company's customers, jeopardize any
attorney-client privilege or contravene any law, rule, regulation, order,
judgment, decree, fiduciary duty or binding agreement entered into prior to the
date of this Agreement. The parties hereto will make appropriate substitute
disclosure arrangements under circumstances in which the restrictions of the
preceding sentence apply. Buyer will hold all such information in confidence to
the extent required by, and in accordance with, the provisions of the
confidentiality agreement, dated July 9, 1998, between Buyer and the Company
(the "Confidentiality Agreement").

          (b) Upon reasonable notice and subject to applicable laws relating to
the exchange of information, Buyer shall, and shall cause its Subsidiaries to,
afford to the officers, employees, accountants, counsel and other
representatives of the Company, access, during normal business hours during the
period prior to the Effective Time, to such information regarding Buyer and its
Subsidiaries as shall be reasonably necessary for the Company to fulfill its
obligations pursuant to this Agreement to prepare the Proxy Statement or which
may be reasonably necessary for the Company to confirm that the representations
and warranties of Buyer contained herein are true and correct and that the
covenants of Buyer contained herein have been performed in all material
respects. Neither Buyer nor any of its Subsidiaries shall be required to provide
access to or to disclose information where such access or disclosure would
violate or prejudice the rights of Buyer's customers, jeopardize any attorney-
client privilege or contravene any law, rule, regulation, order, judgment,
decree, fiduciary duty or binding agreement entered into prior to the date of
this Agreement. The parties hereto will make appropriate substitute disclosure
arrangements under circumstances in which the restrictions of the preceding
sentence apply.

          (c) All information furnished by Buyer to the Company or its
representatives pursuant hereto shall be treated as the sole property of Buyer
and, if the Merger shall not occur, the Company and its representatives shall
return to Buyer all of such written information and all documents, notes,
summaries or other materials containing, reflecting or referring to, or derived
from, such information.  The Company shall, and shall use its best efforts to
cause its representatives to, keep confidential all such information, and shall
not directly or indirectly use such information for any competitive or other
commercial purpose.  The obligation to keep such information confidential shall
continue for two years from the date the proposed Merger is abandoned and shall
not apply to (i) any information which (x) was already in the Company's
possession prior to the disclosure thereof by Buyer; (y) was then generally
known to the public; or (z) was disclosed to the Company by a third party not
bound by an obligation of confidentiality or (ii) disclosures made as required
by law.  It is further agreed that, if in the absence of a protective order or
the receipt of a waiver hereunder the Company is nonetheless, in the opinion of
its counsel, compelled to disclose information concerning Buyer to any tribunal
or governmental body or agency or else stand liable for contempt or suffer other
censure or penalty, the Company may disclose such information to such tribunal
or governmental body or agency without liability hereunder.

          (d) All information furnished by Company to the Buyer or its
representatives pursuant hereto shall be treated as the sole property of Company
and, if the Merger shall not occur, the Buyer and its representatives shall
return to Company all of such written information and all documents, notes,
summaries or other materials containing, reflecting or referring to, or derived
from, such information.  The Buyer shall, and shall use its best efforts to
cause its representatives to, keep confidential all such information, and shall
not directly or indirectly use such information for any competitive or other
commercial purpose.  The obligation to keep such information confidential shall
continue for two years from the date the proposed Merger is abandoned and shall
not apply to (i) any information which (x) was already in the Buyer's possession
prior to the disclosure thereof by Company; (y) was then generally known to the
public; or (z) was disclosed to the Buyer by a third party not bound by an
obligation of 

                                      -38-
<PAGE>
 
confidentiality or (ii) disclosures made as required by law. It is further
agreed that, if in the absence of a protective order or the receipt of a waiver
hereunder the Buyer is nonetheless, in the opinion of its counsel, compelled to
disclose information concerning Company to any tribunal or governmental body or
agency or else stand liable for contempt or suffer other censure or penalty, the
Buyer may disclose such information to such tribunal or governmental body or
agency without liability hereunder.

          (e) No investigation by either of the parties or their respective
representatives shall affect the representations, warranties, covenants or
agreements of the other set forth herein.

          (f) Company shall respond reasonably and in good faith to any timely
request of Buyer to permit a representative of Buyer to attend any meeting of
Company's Board of Directors or the Executive Committee thereof, except to the

steps necessary to duly call, give notice of, convene and hold a special or
annual meeting of its respective stockholders to be held as soon as is
reasonably practicable after the date on which the S-4 becomes effective for the
purpose of voting upon the approval of this Agreement and the consummation of
the transactions contemplated hereby.  The Company and Buyer each will, through
its respective Board of Directors, except to the extent legally required for the
discharge of the fiduciary duties of such board, recommend to its respective
stockholders approval of this Agreement and the transactions contemplated hereby
and such other matters as may be submitted to its stockholders in connection
with this Agreement.  The Company and Buyer shall coordinate and cooperate with
respect to the foregoing matters, with a view towards, among other things,
holding the respective meetings of each party's stockholders on the same day.

          (b) Voting Agreements.  Each of the Company's directors have entered
              -----------------

set forth in Article VII hereof, to consummate the transactions contemplated by
this Agreement and (b) to obtain (and to cooperate with the other party to
obtain) any consent, authorization, order or approval of, or any exemption by,
any Governmental Entity and any other third party which is required to be
obtained by the Company or Buyer or any of their respective Subsidiaries in
connection with the Merger and the Subsidiary Merger and the other transactions
contemplated by this Agreement, and to comply with the terms and conditions of
such consent, authorization, order or approval; provided, however, that neither
                                                --------  -------              
Buyer nor the Company shall be obligated to take any action pursuant to the
foregoing if the taking of such action or such compliance or the obtaining of
such consent, authorization, order or approval is likely, in the good faith
reasonable opinion of Buyer, to result in the imposition of a Burdensome
Condition.

     6.7  Employee Benefit Plans; Existing Agreements.
          --------------------------------------------

          (a) The employees of the Company (the "Company Employees") shall be

situated employees of Buyer participate, to the same extent as comparable
employees of Buyer.  As of the Effective Time, Buyer shall permit the Company
Employees to participate in Buyer's group hospitalization, medical, life and
disability insurance plans on the same terms and conditions as applicable to
comparable employees of Buyer and its Subsidiaries; provided, however, that all

permit the Company Employees to participate in Buyer's defined benefit pension
plan, 401(k) savings plan, employee stock ownership plan ("ESOP") and similar
plans on the same terms and conditions as employees of Buyer and its
Subsidiaries, giving effect to years of service with the Company and its
Subsidiaries (to the extent the Company gave effect) as if such service were
with Buyer, for purposes of eligibility and vesting, but not for benefit accrual
purposes, provided, however, in no event shall said Company employees be
credited with more than three (3) years of service for vesting purposes under

such amounts have been fully accrued for by Company as of the Effective Time and
are in accordance with such amounts provided in past practice by the Company. As
of the Effective Time, all participants under the Company's defined contribution
plan shall become 100% vested in all participant accounts. With respect to
Buyer's welfare benefit plans, (including by example, vacation, sick leave,
severance), Company employees shall have prior service with the Company
recognized for purposes of eligibility to participate, vesting and benefits
accrual purposes.

          (b) Following the Effective Time, Buyer shall honor and shall cause
the Surviving Bank to honor in accordance with their terms all employment,
severance and other compensation agreements and arrangements, including, but not
limited to, severance benefit plans listed in Section 6.7(b)(1) of the Company
Disclosure Schedule, existing prior to the execution of this Agreement and the
agreements and arrangement, as set forth in Section 6.7(b)(2) of the Company
Disclosure Schedule which are between the Company and any director, officer or
employee thereof and which have been disclosed in the Company Disclosure

          (c) As of the Effective Time, Buyer will assume, or will cause First
Savings Bank to assume, the tax qualified plans of the Company Bank as listed in
Section 3.11(a) of the Company Disclosure Schedule.  Neither Buyer nor First
Savings Bank shall be required to make further contributions to such plans.  As
of the Effective Time, all accrued benefits under the plans shall be fully
vested and nonforfeitable.  As soon as practicable after the Effective Time,
Buyer shall terminate or shall cause First Savings Bank to terminate the tax
qualified plans of the Company Bank assumed by Buyer, or First Savings Bank,
pursuant to this Section 6.7(c), and distribution of the accounts of active
participants immediately prior to the Effective Time under the plans shall be
made to the participants and beneficiaries in accordance with the terms of such
plans.

          (a) In the event of any threatened or actual claim, action, suit,
proceeding or investigation, whether civil or administrative, including, without
limitation, any such claim, action, suit, proceeding or investigation in which
any person who is now, or has been at any time prior to the date of this
Agreement, or who becomes prior to the Effective Time, a director or officer or
employee of the Company or any of its Subsidiaries (the "Indemnified Parties")
is, or is threatened to be, made a party based in whole or in part on, or
arising in whole or in part out of, or pertaining to (i) the fact that he is or
was a director, officer or employee of the Company, any of the Subsidiaries of
the Company or any of their respective predecessors or (ii) this Agreement or
any of the transactions contemplated hereby, whether in any case asserted or
arising before or after the Effective Time, the parties hereto agree to
cooperate and use their best efforts to defend against and respond thereto.  It
is understood and agreed that after the Effective Time, Buyer 

                                      -41-
<PAGE>
 
shall indemnify and hold harmless, as and to the extent permitted by Delaware
law, each such Indemnified Party against any losses, claims, damages,
liabilities, costs, expenses (including reasonable attorney's fees and expenses
in advance of the final disposition of any claim, suit, proceeding or
investigation to each Indemnified Party to the fullest extent permitted by law
upon receipt of any undertaking required by applicable law), judgments, fines
and amounts paid in settlement in connection with any such threatened or actual
claim, action, suit, proceeding or investigation, and in the event of any such
threatened or actual claim, action, suit, proceeding or investigation (whether
asserted or arising before or after the Effective Time), the Indemnified Parties
may retain counsel reasonably satisfactory to them after consultation with
Buyer; provided, however, that (1) Buyer shall have the right to assume the
       --------  -------
defense thereof and upon such assumption Buyer shall not be liable to any
Indemnified Party for any legal expenses of other counsel or any other expenses
subsequently incurred by any Indemnified Party in connection with the defense
thereof, except that if Buyer elects not to assume such defense or counsel for
the Indemnified Parties reasonably advises that there are issues which raise
conflicts of interest between Buyer and the Indemnified Parties, the Indemnified
Parties may retain counsel reasonably satisfactory to them after consultation
with Buyer, and Buyer shall pay the reasonable fees and expenses of such counsel
for the Indemnified Parties, (2) Buyer shall in all cases be obligated pursuant
to this paragraph to pay for only one firm of counsel for all Indemnified
Parties, (3) Buyer shall not be liable for any settlement effected without its
prior written consent (which consent shall not be unreasonably withheld) and (4)
Buyer shall have no obligation hereunder to any Indemnified Party when and if a
court of competent jurisdiction shall ultimately determine, and such
determination shall have become final and nonappealable, that indemnification of
such Indemnified Party in the manner contemplated hereby is prohibited by
applicable law. Any Indemnified Party wishing to claim Indemnification under
this Section 6.8, upon learning of any such claim, action, suit, proceeding or

so notify shall not affect the obligations of Buyer under this Section 6.8
except to the extent such failure to notify prejudices Buyer. Buyer's
obligations under this Section 6.8 continue in full force and effect for a
period of six (6) years from the Effective Time; provided, however, that all

Notwithstanding anything to the contrary contained in this Section 6.8(a), in no
event shall Buyer's obligations under this Section 6.8(a) with respect to
indemnification or the advancement of expenses be greater than the obligations
of the Company and its Subsidiaries with respect thereto set forth as of the
date of this Agreement in the Certificate of Incorporation, By-laws or similar
governing documents of the Company and its Subsidiaries.

          (b) Buyer shall cause the persons serving as officers and directors of
the Company immediately prior to the Effective Time to be covered for a period
of six years from the Effective Time by the directors' and officers' liability

therefor policies of at least the same coverage and amounts containing terms and
conditions which are not less advantageous than such policy) with respect to
acts or omissions occurring prior to the Effective Time which were committed by
such officers and directors in their capacity as such.

the Company as to render inadvisable in the reasonable good faith judgment of
Buyer or the Company, the consummation of the Merger (a "Burdensome Condition").

          (d) Consents Under Agreements. The consent, approval or waiver of each

allocable to a fractional share interest for which cash is received).

upon representations and covenants contained in certificates of officers of
Buyer, the Company, the Company Bank and others, including certain shareholders
of the Company.

accountants (at the expense of the Buyer) addressed to Buyer, to the effect that

Stock pursuant to the Option Agreement.

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

dated the date of the Closing, and addressed to Buyer, with respect to the
Company's consolidated financial position and results of operations, which
letters shall be based upon agreed upon procedures to be specified by Buyer,

incurred in connection with the preparation of such letters shall be borne
equally by the Buyer and the Company.

          (j) Subsidiary Merger. Nothing shall have come to the attention of
Buyer which would preclude consummation of the Subsidiary Merger immediately

                       THE TRANSFER OF THIS AGREEMENT IS
                    SUBJECT TO CERTAIN PROVISIONS CONTAINED
                    HEREIN AND TO RESALE RESTRICTIONS UNDER
                     THE SECURITIES ACT OF 1933, AS AMENDED

                             STOCK OPTION AGREEMENT

     STOCK OPTION AGREEMENT, dated as of July 9, 1998 (the "Agreement"), by and
between Pulse Bancorp, Inc., a New Jersey corporation ("Issuer"), and First
Source Bancorp, Inc., a Delaware corporation ("Grantee").

     WHEREAS, Grantee and Issuer have entered into an Agreement and Plan of
Merger (the "Merger Agreement"),  dated July 9, 1998 herewith, providing for,
among other things, the merger of Issuer with and into Grantee; and

     WHEREAS, as a condition and inducement to Grantee's execution of the Merger
Agreement, Grantee has requested that Issuer agree, and Issuer has agreed, to
grant Grantee the Option (as defined below);

     NOW, THEREFORE, in consideration of the foregoing and the respective
representations, warranties, covenants and agreements set forth herein and in
the Merger Agreement, and intending to be legally bound hereby, Issuer and
Grantee agree as follows:

  1. Defined Terms.  Capitalized terms which are used but not defined herein
shall have the meanings ascribed to such terms in the Merger Agreement.

  2. Grant of option.  Subject to the terms and conditions set forth herein,
Issuer hereby grants to Grantee an irrevocable option (the "Option") to purchase
620,940 shares (subject to adjustment as set forth herein) (the "Option Shares")
of common stock, par value $1.00 per share, of Issuer ("Issuer Common Stock") at
a purchase price (subject to adjustment as set forth herein) of $30.30 per
Option Share (the "Purchase Price").

  3. Exercise of Option. (a) Grantee may exercise the Option, in whole or in
part, at any time and from time to time following the occurrence of a Purchase
Event (as defined below); provided, however, that the Option, to the extent not
previously exercised, shall terminate and be of no further force and effect upon
the earliest to occur of (i) the Effective Time, (ii) 12 months after the first
occurrence of a Purchase Event (as defined below), (iii) termination of the
Merger Agreement in accordance with the terms thereof prior to the occurrence of
a Purchase Event (other than a termination of the Merger Agreement by Grantee
pursuant to Section 8.1 (f) thereof) or (iv) 12 months after the termination of
the Merger Agreement by Grantee pursuant to Section 8.1 (f) thereof, provided,
however, that if within 12 months after a termination of the Merger Agreement by
Grantee pursuant to Section 8.1 (f) thereof a Purchase Event shall occur, then
notwithstanding anything to the contrary contained herein, this Option shall
terminate 12 
<PAGE>
 
months after the first occurrence of such Purchase Event; and provided further,
however, that any purchase of shares upon exercise of the Option shall be
subject to compliance with applicable law, including, without limitation, the
Bank Holding Company Act of 1956, as amended (the "Act"); and provided further,
however, that if the Option cannot be exercised on any day because of any
injunction, order or similar restraint issued by a court of competent
jurisdiction, the period during which the Option may be exercised shall be
extended so that the Option shall expire no earlier than on the 10th business
day after such injunction, order or restraint shall have been dissolved or when
such injunction, order or restraint shall have become permanent and no longer
subject to appeal, as the case may be. Notwithstanding anything to the contrary
contained herein, (i) the Option may not be exercised at any time when Grantee
shall be in material breach of any of its covenants or agreements contained in
the Merger Agreement such that Issuer shall be entitled to terminate the Merger
Agreement pursuant to Section 8.1(f) thereof and (ii) this Agreement shall
automatically terminate upon the proper termination of the Merger Agreement by
Issuer pursuant to Section 8.1(f) thereof as a result of the material breach by
Grantee of its covenants or agreements contained in the Merger Agreement.

     (b)  As used herein, a "Purchase Event" means any of the following events:

          (i) Issuer shall have authorized, recommended, publicly proposed or
     entered into an agreement with any person (other than Grantee or any
     affiliate of Grantee or any person acting in concert in any respect with
     Grantee) to effect an Acquisition Transaction (as defined below).  As used
     herein, the term Acquisition Transaction shall mean (A) a merger,
     consolidation or similar transaction involving Issuer or any of its
     Subsidiaries (other than internal mergers, reorganizations, consolidations
     or dissolutions involving only existing Subsidiaries), (B) the disposition,
     by sale, lease, exchange or otherwise, of assets of Issuer or any of its
     Subsidiaries representing 25% or more of the consolidated assets of Issuer
     and its Subsidiaries or (C) the issuance, sale or other disposition of
     (including by way of merger, consolidation, share exchange or any similar
     transaction) securities representing 25% or more of the voting power of
     Issuer or any of its Subsidiaries;

          (ii)  any person (other than Grantee or any affiliate of Grantee or
     any person acting in concert in any respect with Grantee) shall have
     acquired Beneficial Ownership (as such term is defined in Rule l3d-3
     promulgated under the Securities Exchange Act of 1934, as amended (the
     "Exchange Act")) of, or the right to acquire Beneficial Ownership of, or
     any Group (as such term is defined under the Exchange Act) shall have been
     formed which shall have acquired Beneficial Ownership of, or the right to
     acquire Beneficial Ownership of, 25% or more of the then outstanding shares
     of Issuer Common stock,

          (iii)  any person (other than Grantee or any affiliate of Grantee or
     any person acting in concert in any respect with Grantee) shall have
     commenced (as such term is defined in Rule l4d-2 under the Exchange Act) or
     shall have filed a registration statement under the Securities Act of 1933,
     as amended (the "Securities Act") with respect to, a tender offer or
     exchange offer to purchase any shares of Issuer Common Stock and, upon

                                      B-2
<PAGE>
 
     consummation of such offer, such person owns or controls 25% or more of the
     then outstanding shares of Issuer Common Stock (such an offer being
     referred to herein as a "Tender Offer" or an "Exchange Offer,"
     respectively);

          (iv)  the holders of Issuer Common Stock shall not have approved the
     Merger Agreement and the transactions contemplated thereby, at the meeting
     of such stockholders held for the purpose of voting on such agreement, or
     such meeting shall not have been held or shall have been cancelled prior to
     termination of the Merger Agreement, in each case after it shall have been
     publicly announced that any person (other than Grantee or any affiliate of
     Grantee or any person acting in concert in any respect with Grantee) shall
     have made, or disclosed an intention to make, a proposal to engage in an
     Acquisition Transaction; or

          (v) Issuer's Board of Directors shall not have recommended to the
stockholders of Issuer that such stockholders vote in favor of the approval of
the Merger Agreement and the transactions contemplated thereby or shall have
withdrawn or modified such recommendation in a manner adverse to Grantee.

     As used in this Agreement, "person" shall have the meaning specified in
Sections 3 (a) (9) and 13 (d) (3) of the Exchange Act.

     (c) In the event Grantee wishes to exercise the Option, it shall send to
Issuer a written notice (the date of which being herein referred to as the
"Notice Date") specifying (i) the total number of Option Shares it intends to
purchase pursuant to such exercise and (ii) a place and date not earlier than
three business days nor later than 30 business days from the Notice Date for the
closing (the "Closing") of such purchase (the "Closing Date").  If prior
notification to or approval of the Office of Thrift Supervision (the "OTS") or
                                   ----------------------------       ---     
any other regulatory authority is required in connection with such purchase,
Issuer shall cooperate in good faith with Grantee in the filing of the required
notice or application for approval and the obtaining of any such approval and
the period of time that otherwise would run pursuant to the preceding sentence
shall run instead from the date on which, as the case may be (i) any required
notification period has expired or been terminated or (ii) such approval has
been obtained, and in either event, any requisite waiting period shall have
passed.

     4. Payment and Delivery of Certificates. (a) On each Closing Date, Grantee
shall (i) pay to Issuer, in immediately available funds by wire transfer to a
bank account designated by Issuer, an amount equal to the Purchase Price
multiplied by the number of Option Shares to be purchased on such Closing Date
and (ii) present and surrender this Agreement to the Issuer at the address of
the Issuer specified in Section 12(f) hereof.  In addition to any other amounts
payable pursuant to this Section 4(a), upon the first exercise of the Option,
Grantee shall pay an amount, if any, by which (i) $1,055,600 plus the product of
(A) the total number of Option Shares and (B) the difference between the
Market/Tender Offer Price (as defined below) and the Purchase Price exceeds (ii)
$32.00 provided, however, that in no event shall the amount payable pursuant to
this sentence exceed $3,780,000.  As used herein, the "Market/Tender Offer
Price" shall mean the higher of the highest price per share at which a Tender
Offer or Exchange Offer has been made 

                                      B-3
<PAGE>
 
by any person other than Grantee or any affiliate of Grantee or person acting in
concert in any respect with Grantee for at least 25% of the shares of Issuer
Common Stock then outstanding or the highest closing sales price per share of
Issuer Common Stock quoted on the Nasdaq Stock Market ("Nasdaq") (or if Issuer
Common Stock is not quoted on the Nasdaq, the highest bid price per share as
quoted on the principal trading market or securities exchange on which such
shares are traded as reported by a recognized source) within the six-month
period immediately preceding this Agreement.

  (b)  At each Closing, simultaneously with the delivery of immediately
available funds and surrender of this Agreement as provided in Section 4(a)
hereof, Issuer shall deliver to Grantee (A) a certificate or certificates
representing the Option Shares to be purchased at such Closing, which Option
Shares shall be free and clear of all liens, claims, charges and encumbrances of
any kind whatsoever, other than any such lien or encumbrance created by Grantee
and (B) if the Option is exercised in part only, an executed new agreement with
the same terms as this Agreement evidencing the right to purchase the balance of
the shares of Issuer Common Stock purchasable hereunder.  If Issuer shall have
issued rights or any similar securities ("Rights") pursuant to any shareholder
rights, poison pill or similar plan (a "Shareholder Rights Plan") prior or
subsequent to the date of this Agreement and such Rights remain outstanding and
attached to shares of Issuer Common Stock at the time of the issuance of any
Option Shares pursuant to an exercise of all or part of the Option hereunder,
then each Option Share issued pursuant to such exercise shall also represent the
number of Rights issued per share of Issuer Common Stock with terms
substantially the same as and at least as favorable to Grantee as are provided
under the Shareholder Rights Plan as then in effect.

     (c) Certificates for the Option Shares delivered at each Closing shall be
endorsed with a restrictive legend which shall read substantially as follows:

          THE TRANSFER OF THE STOCK REPRESENTED BY THIS CERTIFICATE MAY BE
     SUBJECT TO RESTRICTIONS ARISING UNDER THE SECURITIES ACT OF 1933, AS
     AMENDED, AND PURSUANT TO THE TERMS OF A STOCK OPTION AGREEMENT DATED AS OF
     JULY 9, 1998.  A COPY OF SUCH AGREEMENT WILL BE PROVIDED TO THE HOLDER
     HEREOF WITHOUT CHARGE UPON RECEIPT BY THE ISSUER OF A WRITTEN REQUEST
     THEREFOR.

     It is understood and agreed that: (i) the reference to the resale
restrictions of the Securities Act in the above legend shall be removed by
delivery of substitute certificate (s) without such legend if Grantee shall have
delivered to Issuer a copy of a letter from the staff of the Securities and
Exchange Commission (the "SEC"), or an opinion of outside counsel reasonably
satisfactory to Issuer in form and substance reasonably satisfactory to Issuer
and its counsel, to the effect that such legend is not required for purposes of
the Securities Act; (ii) the reference to the provisions of this Agreement in
the above legend shall be removed by delivery of substitute certificate(s)
without such reference if the shares have been sold or transferred in compliance
with the provisions of this Agreement and under circumstances that do not
require the retention of such reference; and (iii) the legend shall 

                                      B-4
<PAGE>
 
be removed in its entirety if the conditions in the preceding clauses (i) and
(ii) are both satisfied. In addition, such certificates shall bear any other
legend as may be required by law.

     5.  Representations and Warranties of Issuer.  Issuer hereby represents and
warrants to Grantee as follows:

  (a)  Due Authorization.  Issuer has full corporate power and authority to
enter into this Agreement and to consummate the transactions contemplated

Incorporation") or By-Laws of Issuer or the certificates of incorporation, by-
laws or similar governing documents of any of its Subsidiaries or (ii) (x)
assuming that all of the consents and approvals required under applicable law
for the purchase of shares upon the exercise of the Option are duly obtained,

result in the creation of any lien, pledge, security interest, charge or other
encumbrance upon any of the respective properties or assets of Issuer or any of

bond, mortgage, indenture, deed of trust, license, lease, agreement or other
instrument or obligation to which Issuer or any of its Subsidiaries is a party,
or by which they or any of their respective properties or assets may be bound or

  (c)  Authorized Stock.  Issuer has taken all necessary corporate and other
action to authorize and reserve and to permit it to issue, and, at all times
from the date of this Agreement until the obligation to deliver Issuer Common
Stock upon the exercise of the Option, will have reserved for issuance, upon

exercise the Option, and Issuer will take all necessary corporate action to
authorize and reserve for issuance all additional shares of Issuer Common Stock
(together with any Rights which may have been issued with respect thereto) or
other securities which may be issued pursuant to Section 7 upon exercise of the
Option.  The shares of Issuer Common Stock to be issued upon due exercise of the
Option, including all additional shares of Issuer Common Stock (together with
any Rights which may have been issued with respect thereto) or other securities
which may be issuable pursuant to Section 7, upon issuance pursuant hereto,
shall be duly and validly issued, fully paid and nonassessable, and shall be
delivered free and clear of all liens, claims, charges and encumbrances of any
kind or nature whatsoever (except any such lien or encumbrance created by
Grantee), including any preemptive rights of any stockholder of Issuer.

                                      B-5
<PAGE>
 
  (d)  Board Action.  By action of the Board of Directors of Issuer prior to the
execution of this Agreement, resolutions were duly adopted approving the
execution, delivery and performance of this Agreement, any purchase or other
transaction respecting Issuer Common Stock provided for herein, and the other
transactions contemplated hereby.  Accordingly, the provisions of the New Jersey
Business Corporations Act as they relate to Issuer and Article XV of Issuer's
Certificate of Incorporation do not and will not apply to this Agreement or any
of the other transactions contemplated hereby.

     6.  Representations and Warranties of Grantee.  Grantee hereby represents
and warrants to Issuer that:

  (a) Due Authorization.  Grantee has corporate power and authority to enter
into this Agreement and, subject to any approvals or consents referred to
herein, to consummate the transactions contemplated hereby.  The execution and
delivery of this Agreement and the consummation of the transactions contemplated
hereby have been duly authorized by all necessary corporate action on the part
of Grantee.  This Agreement has been duly executed and delivered by Grantee.

  (b) Purchase Not for Distribution.  This Option is not being acquired with a
view to the public distribution thereof and neither this Option nor any Option
Shares will be transferred or otherwise disposed of except in a transaction
registered or exempt from registration under the Securities Act.

     7.  Adjustment upon Changes in Capitalization, etc. (a) In the event (i) of
any change in Issuer Common Stock by reason of a stock dividend, stock split,
split-up, recapitalization, combination, exchange of shares or similar
transaction or (ii) that any Rights issued by Issuer shall become exercisable,
the type and number of shares or securities subject to the Option, and the
Purchase Price therefor, shall be adjusted appropriately, and, in the case of
any of the transactions described in clause (i) above, proper provision shall be
made in the agreements governing such transaction so that Grantee shall receive,
upon exercise of the Option, the number and class of shares or other securities
or property that Grantee would have received in respect of Issuer Common Stock
if the Option had been exercised immediately prior to such event, or the record
date therefor, as applicable.  If any additional shares of Issuer Common Stock
are issued after the date of this Agreement (other than pursuant to an event
described in the first sentence of this Section 7 (a), the number of shares of
Issuer Common Stock subject to the option shall be adjusted so that, after such
issuance, the Option, together with any shares of Issuer Common Stock previously
issued pursuant hereto, equals 19.9% of the number of shares of Issuer Common
Stock then issued and outstanding, without giving effect to any shares subject
to or Previously issued pursuant to the option.

  (b) In the event that Issuer shall enter into an agreement (i) to consolidate
with or merge into any person, other than Grantee or one of its Subsidiaries,
and shall not be the continuing or surviving corporation of such consolidation
or merger, (ii) to permit any person, other than Grantee or one of its
Subsidiaries, to merge into Issuer and Issuer shall be the continuing or
surviving corporation, but, in connection with such merger, the then outstanding
shares of Issuer 

                                      B-6
<PAGE>
 
Common Stock shall be changed into or exchanged for stock or other securities of
Issuer or any other person or cash or any other property or the outstanding
shares of Issuer Common Stock immediately prior to such merger shall after such
merger represent less than 50% of the outstanding shares and share equivalents
of the merged company, or (iii) to sell or otherwise transfer all or
substantially all of its assets to any person, other than Grantee or one of its
Subsidiaries, then, and in each such case, the agreement governing such
transaction shall make proper provisions so that the Option shall, upon the
consummation of any such transaction and upon the terms and conditions set forth
herein, be converted into, or exchanged for, an option (the "Substitute
Option"), at the election of Grantee, of either (I) the Acquiring Corporation
(as defined below), (II) any person that controls the Acquiring Corporation, or
(III) in the case of a merger described in clause (ii), the Issuer (such person
being referred to as the "Substitute Option Issuer").

  (c) The Substitute Option shall have the same terms as the Option, provided,
that if the terms of the Substitute Option cannot, for legal reasons, be the
same as the Option, such terms shall be as similar as possible and in no event
less advantageous to Grantee.  The Substitute Option Issuer shall also enter
into an agreement with the then holder or holders of the Substitute Option in
substantially the same form as this Agreement, which shall be applicable to the
Substitute Option.

  (d) The Substitute Option shall be exercisable for such number of shares of
the Substitute Common Stock (as hereinafter defined) as is equal to the Assigned
Value (as hereinafter defined) multiplied by the number of shares of Issuer
Common Stock for which the Option was theretofore exercisable, divided by the
Average Price (as hereinafter defined).  The exercise price of the Substitute
Option per share of the Substitute Common Stock (the "Substitute Purchase
Price") shall then be equal to the Purchase Price multiplied by a fraction in
which the numerator is the number of shares of the Issuer Common Stock for which
the Option was theretofore exercisable and the denominator is the number of
shares of the Substitute Common Stock for which the Substitute Option is
exercisable.

  (e) The following terms have the meanings indicated:

          (I) "Acquiring Corporation" shall mean (i) the continuing or surviving
     corporation of a consolidation or merger with Issuer (if other than
     Issuer), (ii) Issuer in a merger in which Issuer is the continuing or
     surviving person, and (iii) the transferee of all or substantially all of
     the Issuer's assets (or the assets of  its Subsidiaries).

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

          (III)  "Assigned Value" shall mean the highest of (i) the price per
     share of Issuer Common Stock at which a tender offer or exchange offer
     therefor has been made by any person (other than Grantee), (ii) the price
     per share of Issuer Common Stock to be paid by any person (other than the
     Grantee) pursuant to an agreement with Issuer, and (iii) the highest
     closing sales price per share of Issuer Common Stock quoted on the Nasdaq
     (or if 

                                      B-7
<PAGE>
 
     Issuer Common Stock is not quoted on the Nasdaq, the highest bid
     price per share as quoted on the principal trading market or securities
     exchange on which such shares are traded as reported by a recognized
     source) within the six-month period immediately preceding the agreement;
     provided, however, that in the event of a sale of less than all of Issuer's
     assets, the Assigned Value shall be the sum of the price paid in such sale
     for such assets and the current market value of the remaining assets of
     Issuer as determined by a nationally recognized investment banking firm
     selected by Grantee or by a Grantee Majority, divided by the number of
     shares of Issuer Common Stock outstanding at the time of such sale.  In the
     event that an exchange offer is made for the Issuer Common Stock or an
     agreement is entered into for a merger or consolidation involving
     consideration other than cash, the value of the securities or other
     property issuable or deliverable in exchange for the Issuer Common Stock
     shall be determined by a nationally recognized investment banking firm
     mutually selected by Grantee and Issuer (or if applicable, Acquiring
     Corporation), provided that if a mutual selection cannot be made as to such
     investment banking firm, it shall be selected by Grantee (or a majority of
     interest of the Grantees if there shall be more than one Grantee (a
     "Grantee Majority").

          (IV) "Average Price" shall mean the average closing price of a share
     of the Substitute Common Stock for the one year immediately preceding the
     consolidation, merger or sale in question; but in no event higher than the
     closing price of the shares of the Substitute Common Stock on the day
     preceding such consolidation, merger or sale; provided that if Issuer is
     the issuer of the Substitute Option, the Average Price shall be computed
     with respect to a share of common stock issued by Issuer, the person
     merging into Issuer or by any company which controls or is controlled by
     such merging person, as Grantee may elect.

  (f) In no event, pursuant to any of the foregoing paragraphs, shall the
Substitute Option be exercisable for more than 19.9% of the aggregate of the
shares of the Substitute Common Stock outstanding prior to exercise of the
Substitute Option.  In the event that the Substitute Option would be exercisable
for more than 19.9% of the aggregate of the shares of Substitute Common Stock
but for this clause (f), the Substitute Option Issuer shall make a cash payment
to Grantee equal to the excess of (i) the value of the Substitute Option without
giving effect to the limitation in this clause (f) over (ii) the value of the
Substitute Option after giving effect to the limitation in this clause (f).
This difference in value shall be determined by a nationally recognized
investment banking firm selected by Grantee (or a Grantee Majority).

  (g) Issuer shall not enter into any transaction described in subsection (b) of
this Section 7 unless the Acquiring Corporation and any person that controls the
Acquiring Corporation assume in writing all the obligations of Issuer hereunder
and take all other actions that may be necessary so that the provisions of this
Section 7 are given full force and effect (including, without limitation, any
action that may be necessary so that the shares of Substitute Common Stock are
in no way distinguishable from or have lesser economic value than other shares
of common stock issued by the Substitute Option Issuer).

                                      B-8
<PAGE>
 
  (h) The provisions of Sections 8 and 9 shall apply to any securities for which
the Option becomes exercisable pursuant to this Section 7 and as applicable,
references in such sections to "Issuer", "Option", "Purchase Price" and "Issuer
Common Stock" shall be deemed to be references to "Substitute Option Issuer",
"Substitute Option", "Substitute Purchase Price" and "Substitute Common Stock",
respectively.

  8.  Registration Rights.  Issuer shall, if requested by Grantee (or if
applicable, a Grantee Majority) at any time and from time to time within three
years of the date on which the Option first becomes exercisable, as
expeditiously as possible prepare and file up to two registration statements
under the Securities Act if such registration is necessary in order to permit
the sale or other disposition of any or all shares of Issuer Common Stock or
other securities that have been acquired by or are issuable to Grantee upon
exercise of the Option in accordance with the intended method of sale or other
disposition stated by Grantee, including a "shelf" registration statement under
Rule 415 under the Securities Act or any successor provision, and Issuer shall
use its best efforts to qualify such shares or other securities under any
applicable state securities laws.  Issuer shall use its best efforts to cause
each such registration statement to become effective, to obtain all consents or
waivers of other parties which are required therefor and to keep such
registration statement effective for such period not in excess of 180 days from
the day such registration statement first becomes effective as may be reasonably
necessary to effect such sale or other disposition.  Any registration statement
prepared and filed under this Section 8, and any sale covered thereby, shall be
at Issuer's expense except for underwriting discounts or commissions, brokers'
fees and the fees and disbursements of Grantee's counsel related thereto.
Grantee shall provide all information reasonably requested by Issuer for
inclusion in any registration statement to be filed hereunder.  If during the
time periods referred to in the first sentence of this Section 8 Issuer effects
a registration under the Securities Act of Issuer Common Stock for its own
account or for any other stockholders of Issuer (other than on Form S-4 or Form
S-8, or any successor forms or any form with respect to a dividend reinvestment
or similar plan), it shall allow Grantee the right to participate in such
registration, and such participation shall not affect the obligation of Issuer
to effect two registration statements for Grantee under this Section 8;
provided, however, that, if the managing underwriters of such offering advise
Issuer in writing that in their opinion the number of shares of Issuer Common
Stock requested by Grantee to be included in such registration, together with
the shares of Issuer Common Stock proposed to be included in such registration,
exceeds the number which can be sold in such offering, Issuer shall include the
shares requested to be included therein by Grantee pro rata with the shares
intended to be included therein by Issuer.  In connection with any registration
pursuant to this Section 8, Issuer and Grantee shall provide each other and any
underwriter of the offering with customary representations, warranties,
covenants, indemnification and contribution in connection with such
registration.  Notwithstanding anything to the contrary contained herein, in no
event shall Issuer be obligated to effect more than two registrations pursuant
to the first sentence of this Section 8 by reason of the fact that there shall
be more than one Grantee as a result of any assignment of this Agreement or
division of this Agreement pursuant to Section 10 hereof.

  9.  Listing.  If Issuer Common Stock or any other securities to be acquired
upon exercise of the Option are then authorized for quotation on the Nasdaq or
any securities exchange, Issuer, 

                                      B-9
<PAGE>
 
upon the request of Grantee, will promptly file an application to authorize for
quotation the shares of Issuer Common Stock or other securities to be acquired
upon exercise of the Option on the Nasdaq or such other securities exchange and
will use its best efforts to obtain approval of such listing as soon as
practicable.

  10.   Division of Option.  This Agreement (and the Option granted hereby) are
exchangeable, without expense, at the option of Grantee, upon presentation and
surrender of this Agreement at the principal office of Issuer for other
Agreements providing for Options of different denominations entitling the holder
thereof to purchase in the aggregate the same number of shares of Issuer Common
Stock purchasable hereunder.  The terms "Agreement" and "Option" as used herein
include any other Agreements and related Options for which this Agreement (and
the Option granted hereby) may be exchanged.  Upon receipt by Issuer of evidence
reasonably satisfactory to it of the loss, theft, destruction or mutilation of
this Agreement, and (in the case of loss, theft or destruction) of reasonably
satisfactory indemnification, and upon surrender and cancellation of this
Agreement, if mutilated, Issuer will execute and deliver a new Agreement of like
tenor and date.  Any such new Agreement executed and delivered shall constitute
an additional contractual obligation on the part of Issuer, whether or not the
Agreement so lost, stolen, destroyed or mutilated shall at any time be
enforceable by anyone.

  11. Rights Agreement.  Issuer shall not approve or adopt, or propose the
approval and  adoption of, any Shareholder Rights Plan unless such Shareholder
Rights Plan contains terms which provide, to the reasonable satisfaction of
Grantee, that (a) the Rights issued pursuant thereto will not become exercisable
by virtue of the fact that (i) Grantee is the Beneficial Owner of shares of
Issuer Common Stock (x) acquired or acquirable pursuant to the grant or exercise
of this Option and (y) held by Grantee or any of its Subsidiaries as Trust
Account Shares or DPC Shares or (ii) while Grantee is the Beneficial Owner of
the shares of Issuer Common Stock described in clause (a) (i), an Acquisition
Transaction involving Issuer or any of its Subsidiaries, on the one hand, and
Grantee, any of its Subsidiaries, on the other hand, is proposed, agreed to or
consummated and (b) no restrictions or limitations with respect to the exercise
of any Rights acquired or acquirable by Grantee will result or be imposed by
virtue of the fact that Grantee is the Beneficial Owner of the shares of Issuer
Common Stock described in clause (a) (i) of this Section 11.

     12.  Miscellaneous. (a) Expenses.  Except as otherwise provided in Section
8 hereof, each of the parties hereto shall bear and pay all costs and expenses
incurred by it or on its behalf in connection with the transactions contemplated
hereunder, including fees and expenses of its own financial consultants,
investment bankers, accountants and counsel.

     (b)  Waiver and Amendment.  Any provision of this Agreement may be waived
at any time by the party that is entitled to the benefits of such provision.
This Agreement may not be modified, amended, altered or supplemented except upon
the execution and delivery of a written agreement executed by the parties
hereto.

     (c) Entire Agreement; No Third-Party Beneficiary; Severability.  This
Agreement, together with the Merger Agreement and the other agreements and
instruments referred to herein 

                                      B-10
<PAGE>
 
and therein, (a) constitutes the entire agreement and supersedes all prior
agreements and understandings, both written and oral, between the parties with
respect to the subject matter hereof and (b) is not intended to confer upon any
person other than the parties hereto any rights or remedies hereunder.
Notwithstanding anything to the contrary contained in this Agreement or the
Merger Agreement, this Agreement shall be deemed to amend the confidentiality
agreement between Issuer and Grantee so as to permit Grantee to enter into this
Agreement and exercise all of its rights hereunder, including its right to
acquire Issuer Common Stock upon exercise of the Option. If any term, provision,
covenant or restriction of this Agreement is held by a court of competent
jurisdiction or a federal or state regulatory agency to be invalid, void or
unenforceable, the remainder of the terms, provisions, covenants and
restrictions of this Agreement shall remain in full force and effect and shall
in no way be affected, impaired or invalidated. If for any reason such court or
regulatory agency determines that the Option does not permit Grantee to acquire
the full number of shares of Issuer Common Stock as provided in Section 3 hereof
(as adjusted pursuant to Section 7 hereof), it is the express intention of
Issuer to allow Grantee to acquire such lesser number of shares as may be
permissible without any amendment or modification hereof.

     (d) Governing Law.  This Agreement shall be governed and construed in
accordance with the laws of the State of New Jersey without regard to any
applicable conflicts of law rules.

     (e) Descriptive Headings.  The descriptive headings contained herein are
for convenience of reference only and shall not affect in any way the meaning or
interpretation of this Agreement.

South River, NJ 08882

Ladies and Gentlemen:

     Pulse Bancorp, Inc. ("Pulse") and First Source Bancorp, Inc. ("First
Source") have entered into an Agreement and Plan of Reorganization, dated as of
July 9, 1998 (the "Agreement"), pursuant to which Pulse will be merged with and
into First Source (the "Merger").  Upon consummation of the Merger, each share
of Pulse common stock, par value $1.00 per share, issued and outstanding
immediately prior to the Merger will be converted into the right to receive
between 3.2 and 3.764 shares, based on the Average Closing Price (as defined in
the Agreement), of First Source common stock, par value $0.01 per share (the
"Exchange Ratio"), subject to adjustment as described in the Agreement.  The
terms and conditions of the Merger are more fully set forth in the Agreement.
You have requested our opinion as to the fairness, from a financial point of
view, of the Exchange Ratio to the holders of Pulse Shares.

     Sandler O'Neill & Partners, L.P., as part of its investment banking
business, is regularly engaged in the valuation of financial institutions and
their securities in connection with mergers and acquisitions and other corporate
transactions.  In connection with this opinion, we have reviewed, among other
things: (i) the Agreement and exhibits thereto; (ii) the Stock Option Agreement,
dated as of July 9, 1998, by and between Pulse and First Source; (iii) certain
publicly available financial statements of Pulse and other historical financial
information provided by Pulse that we deemed relevant; (iv) certain publicly
available financial statements of First Source and other historical financial
information provided by First Source that we deemed relevant; (v) certain
financial analyses and forecasts of Pulse prepared by and reviewed with
management of Pulse and the views of senior management of Pulse regarding
Pulse's past and current business, operations, results thereof, financial
condition and future prospects; (vi) certain financial analyses and forecasts of
First Source prepared by and reviewed with management of First Source and the
views of senior management of First Source regarding First Source's past and
current business, operations, results thereof, financial condition and future
prospects; (vii) the pro forma impact of the Merger; (viii) the publicly
reported historical price and trading activity for Pulse's and First Source's
common stock, including a comparison of certain financial and stock market
information for Pulse and First Source with similar publicly available
information for certain other companies the securities of which are publicly
traded; (ix) the financial terms of recent business combinations in the savings
institution

industry, to the extent publicly available; (x) the current market environment
generally and the banking environment in particular; and (xi) such other
information, financial studies, analyses and investigations and financial,
economic and market criteria as we considered relevant.  We did not act as
Pulse's financial advisor in connection with its consideration of the Merger or
in connection with the negotiation of the Agreement, and we have not been asked
to, and did not, solicit indications of interest in a potential transaction from
other third parties.

     In performing our review, we have assumed and relied upon, without
independent verification, the accuracy and completeness of all the financial
information, analyses and other information that was publicly available or
otherwise furnished to, reviewed by or discussed with us, and we do not assume
any responsibility or liability for the accuracy or completeness thereof.  We
did not make an independent evaluation or appraisal of the specific assets, the
collateral securing assets or the liabilities (contingent or otherwise) of Pulse
or First Source or any of their subsidiaries, or the collectibility of any such
assets, nor have we been furnished with any such evaluations or appraisals.
With respect to the financial projections reviewed with management, we have
assumed that they have been reasonably prepared on bases reflecting the best
currently available estimates and judgments of the respective managements of the
respective future financial performances of Pulse and First Source and that such
performances will be achieved, and we express no opinion as to such financial
projections or the assumptions on which they are based.  We have also assumed
that there has been no material change in Pulse's or First Source's assets,
financial condition, results of operations, business or prospects since the date
of the most recent financial statements made available to us.  We have assumed
in all respects material to our analysis that Pulse and First Source will remain
as going concerns for all periods relevant to our analyses, that all of the
representations and warranties contained in the Agreement and all related
agreements are true and correct, that each party to such agreements will perform
all of the covenants required to be performed by such party under such
agreements, that the conditions precedent in the Agreement are not waived and
that the Merger will be accounted for as a pooling of interests and will qualify
as a tax-free reorganization for federal income tax purposes.

     Our opinion is necessarily based on financial, economic, market and other
conditions as in effect on, and the information made available to us as of, the
date hereof.  Events occurring after the date hereof could materially affect
this opinion.  We have not undertaken to update, revise or reaffirm this opinion
or otherwise comment upon events occurring after the date hereof.  We are
expressing no opinion herein as to what the value of First Source common stock
will be when issued to Pulse's shareholders pursuant to the Agreement or the
prices at which Pulse's or First Source's common stock will trade at any time.

     We have been retained by you to render this opinion and will receive a fee
for our services. In the past, we have also provided certain other investment
banking services for Pulse and have

received compensation for such services.  As we have previously advised you, in
the past we have also provided certain investment banking services for First
Source and currently provide general advisory services for First Source and have
received compensation for such services.   In addition, we have advised you that
we may in the future provide certain other investment banking services for First
Source, and will receive compensation for such services.

     In the ordinary course of our business as a broker-dealer, we may buy
securities from and sell securities to both Pulse and First Source.  In
addition, we may actively trade the equity securities of Pulse and First Source
for our own account and for the accounts of our customers and, accordingly, may
at any time hold a long or short position in such securities.

     Our opinion is directed to the Board of Directors of Pulse in connection
with its consideration of the Merger and does not constitute a recommendation to
any stockholder of Pulse as to how such stockholder should vote at any meeting
of stockholders called to consider and vote upon the Merger. Our opinion is not
to be quoted or referred to, in whole or in part, in a registration statement,
prospectus, proxy statement or in any other document, nor shall this opinion be
used for any other purposes, without Sandler O'Neill's prior written consent;
provided, however, that we hereby consent to the inclusion of this opinion as an
annex to Pulse's and First Source's Joint Proxy Statement/Prospectus dated the
date hereof and to the references to this opinion therein.

     Based upon and subject to the foregoing, it is our opinion, as of the date
hereof, that the Exchange Ratio is fair, from a financial point of view, to the
holders of Pulse Shares.


                                        Very truly yours,

The Board of Directors
First Source Bancorp, Inc.
1000 Woodbridge Center Drive
Woodbridge,  New Jersey  07095

Members of the Board:

You have requested our opinion as investment bankers that the Exchange Ratio in
the Merger (the "Merger") between First Source Bancorp, Inc., Woodbridge, New
Jersey ("First Source") and Pulse Bancorp, Inc., South River, New Jersey
("Pulse") the holding company for Pulse Savings Bank ("Pulse Savings Bank") as
provided and described in the Merger Agreement is fair to the holders of First
Source from a financial point of view.

Pursuant to the Agreement and Plan of Merger dated July 9, 1998 (the
"Agreement"), Pulse shall merge with and into First Source, and each share of
Pulse's issued and outstanding common stock will be converted into and become
the right to receive a minimum of 3.2 shares and a maximum of 3.764 shares
subject to certain adjustments as set forth in the Agreement (the "Exchange
Ratio").  The exact Exchange Ratio shall be determined as follows: (i) if First
Source's Average Closing Price (as defined) is equal to or greater than $10.00,
the Exchange Ratio shall equal 3.2 shares; (ii) if First Source's Average
Closing Price is greater than $8.50 but less than $10.00, the Exchange Ratio
shall equal the number of shares determined by dividing $32.00 by the Average
Closing Price; or (iii) if First Source's Average Closing Price is equal to or
less than $8.50, the Exchange Ratio shall be 3.764 shares.  We have assumed that
the Merger will qualify as a tax free transaction for the stockholders of Pulse
and be accounted for by First Source as a pooling-of-interests transaction.

Ryan, Beck & Co., as a customary part of its investment banking business, is
engaged in the valuation of banking and savings institutions and their
securities in connection with mergers and acquisitions.  In conducting our
investigation and analysis of the Merger, we have met separately with members of
senior management of First Source and Pulse to discuss their respective
operations, historical financial statements, strategic plans and future
prospects.  We have reviewed and analyzed material prepared in connection with
the Merger, including but not limited to the following: (i) the Agreement and
related documents; (ii) the Joint Proxy Statement / Prospectus; (iii) First
Source's Annual Reports to Shareholders and Annual Reports on Form 10-K for the
years ended December 31, 1997, 1996, and 1995, and First Source's Quarterly
Reports on Form 10-Q for the periods ended June 30, 1998, March 31, 1998,
September 30,

1997, June 30, 1997 and March 31, 1997; (iv) First Source's Registration
Statement filed on Form S-1/A dated February 9, 1998 in connection with its
conversion from a mutual holding company structure to a stock holding company
structure; (v) Pulse's Annual Reports to Shareholders and Annual Reports on Form
10-K for the years ended September 30, 1997, 1996, and 1995, and Pulse's
Quarterly Reports on Form 10-Q for the periods ended June 30, 1998, March 31,
1998, December 31, 1997, June 30, 1997 and March 31, 1997; (vi) the historical
stock prices and trading volume of First Source's common stock; (vii) the
historical stock prices and trading volume of Pulse's common stock; (viii) the
publicly available financial data of thrift organizations which Ryan, Beck
deemed generally comparable to First Source; (ix) the publicly available
financial data of thrift organizations which Ryan, Beck deemed generally
comparable to Pulse; (x) the terms of recent acquisitions of thrift
organizations which Ryan, Beck deemed generally comparable in whole or in part
to Pulse; and (xi) the potential pro-forma impact of the Merger on First
Source's financial condition, operating results and per share figures. We also
conducted or reviewed such other studies, analyses, inquiries and examinations
as we deemed appropriate. Ryan, Beck as part of its review of the Merger, also
analyzed First Source's ability to consummate the Merger.

While we have taken care in our investigation and analyses, we have relied upon
and assumed the accuracy, completeness and fairness of the financial and other
information provided to us by the respective institutions or which was publicly
available and have not assumed any responsibility for independently verifying
such information.  We have also relied upon the managements of First Source and
Pulse as to the reasonableness and achievability of the financial and operating
forecasts and projections (and the assumptions and bases therefor) provided to
us and in certain instances we have made certain adjustments to such financial
and operating forecasts which in our judgment were appropriate under the
circumstances.  In addition, we have assumed with your consent that such
forecasts and projections reflect the best currently available estimates and
judgments of the respective managements.  We are not experts in the evaluation
of allowances for loan losses.  Therefore, we have not assumed any
responsibility for making an independent valuation of the adequacy of the
allowances for loan losses set forth in the balance sheets of First Source and
Pulse at June 30, 1998, and we assumed such allowances were adequate and comply
fully with applicable law, regulatory policy and sound banking practice as of
the date of such financial statements.  We also assumed that the Merger in all
respects is, and will be consummated in compliance with all laws and regulations
applicable to First Source and Pulse.  We have not made or obtained any
independent evaluations or appraisals of the assets and liabilities of either
First Source or Pulse or their respective subsidiaries, nor have we reviewed any
individual loan files of First Source or Pulse or their respective subsidiaries.

In conducting our analysis and arriving at our opinion as expressed herein, we
have considered such financial and other factors as we have deemed appropriate
in the circumstances.  In rendering our opinion, we have assumed that in the
course of obtaining the necessary regulatory

approvals for the Merger, no conditions will be imposed that will have a
material adverse effect on the contemplated benefits of the Merger to First
Source. We have not opined on the fairness of the transaction should First
Source elect to increase the Exchange Ratio above the maximum in order to avoid
a termination of the Agreement by Pulse because the Average Closing Price of
First Source Common Stock is less than $8.50.

Our opinion is necessarily based on economic, market and other conditions and
projections as they exist and can be evaluated on the date hereof.  Ryan, Beck
did not express any opinion as to the price or range of prices at which First
Source Common Stock might trade subsequent to the Merger.

We have been retained by the Board of Directors of First Source as an
independent contractor to act as financial advisor to First Source with respect
to the Merger and will receive a fee for our services.  Ryan, Beck has had a
prior investment banking relationship with First Source.  Ryan, Beck was the
sole underwriter for First Source, which was then known as First Savings Bank,
in both its May, 1992 reorganization from a mutual to a federal mutual holding
company and its May, 1995 secondary stock offering.  Ryan, Beck was also a
financial advisor, but not an underwriter for First Source in its "second step"
conversion dated April 9, 1998 from a mutual holding company structure to a
stock holding company structure. Ryan, Beck also acted as financial advisor with
respect to the sale of a branch office.  Additionally, Ryan, Beck's research
department has issued research reports on First Source and comments on First
Source in its periodic commentaries.  Ryan, Beck is also a market maker in First
Source's stock.  Ryan, Beck has not had an investment banking relationship with
Pulse since 1986.  Ryan, Beck was the sole underwriter of Pulse's conversion,
which was then known as Pulawski Savings and Loan Association, from a mutual to
a stock savings and loan association in September, 1986.  Ryan, Beck is a market
maker in Pulse's stock.  Ryan, Beck's research department does not cover Pulse.

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

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

Very truly yours,

     (c) Actual transference of the Award requires no, nor allows any,
discretion by the Trustee.

3.   TYPES OF AWARDS AND RELATED RIGHTS.
     -----------------------------------

     The following Awards and related rights as described below in Paragraphs 6
through 12 hereof may be granted under the Plan:

     (a)  Non-statutory Stock Options
     (b)  Incentive Stock Options
     (c)  Limited Rights
     (d)  Stock Awards

4.   STOCK SUBJECT TO THE PLAN.
     ------------------------- 

     Subject to adjustment as provided in Section 15 hereof, the maximum number
of shares of Common Stock reserved for Awards under the Plan is 2,317,051
shares, which number may not be in excess of 14% of the number of shares of the
Common Stock sold in the Company's Subscription and Community Offering completed
on April 8, 1998 (not including those shares of Common Stock issued in exchange
for shares of First Savings Bank, SLA Common Stock).  Subject to adjustment as
provided in Section 15 hereof, the maximum number of shares of Common Stock
reserved hereby for purchase pursuant to the exercise of Options and Option-
related Awards granted under the Plan is 1,655,037 shares, which number may not
be in excess of 10% of the number of shares of Common Stock sold in the
Company's Subscription and Community Offering completed on April 8, 1998 (not
including those shares of Common Stock issued in exchange for shares of First
Savings Bank, SLA Common Stock).  The maximum number of the shares of Common
Stock reserved for award as Stock Awards is 662,014 shares, which number is not
in excess of 4% of the number of shares of Common Stock sold in the Company's
Subscription and Community Offering completed on April 8, 1998 (not including
those shares of Common Stock issued in exchange for shares of First Savings
Bank, SLA Common Stock).  These shares of Common Stock may be either authorized
but unissued shares or authorized shares previously issued and reacquired by the
Holding Company.  To the extent that Options and Stock Awards are granted under
the Plan, the shares underlying such Awards will be unavailable for any other
use including future grants under the Plan except that, to the extent that Stock
Awards or Options terminate, expire, or are forfeited without having been
exercised (or in cases where a Limited Right has been granted in connection with
an option, the amount of such Limited Right received in lieu of the exercise of
such option), new Awards may be made with respect to those shares underlying
such terminated, expired or forfeited Options or Stock Awards.

5.  ELIGIBILITY.
    ----------- 

     Subject to the terms herein, all Employees and Outside Directors shall be
eligible to receive Awards under the Plan.

                                      -5-

6.  NON-STATUTORY STOCK OPTIONS.
    --------------------------- 

     The Committee may, subject to the limitations of the Plan and the
availability of  shares reserved but unawarded under the Plan, from time to
time, grant Non-statutory Stock Options to Employees and Outside Directors, upon
such terms and conditions as the Committee may determine and grant Non-statutory
Stock Options in exchange for and upon surrender of previously granted Awards
under this Plan under such terms and conditions as the Committee may determine.
Non-statutory Stock Options granted under this Plan are subject to the following
terms and conditions:

     (a) Exercise Price.  The Exercise Price of each Non-statutory Stock Option
         --------------                                                        
shall be determined by the Committee.  Such Exercise Price shall not be less
than 100% of the Fair Market Value of the Holding Company's Common Stock on the
Date of Grant.  Shares of Common Stock underlying a Non-statutory Stock Option
may be purchased only upon full payment of the Exercise Price or upon operation
of an Alternate Option Payment Mechanism set out in Section 11 hereof.

     (b) Terms of Non-statutory Stock Options.  The term during which each Non-
         ------------------------------------                                 
statutory Stock Option may be exercised shall be determined by the Committee,
but in no event shall a Non-statutory Stock Option be exercisable in whole or in
part more than 10 years from the Date of Grant.  The Committee shall determine
the date on which each Non-statutory Stock Option shall become exercisable. The
shares of Common Stock underlying each Non-statutory Stock Option installment
may be purchased in whole or in part by the Participant at any time during the
term of such Non-statutory Stock Option after such installment becomes
exercisable.  The Committee may, in its sole discretion, accelerate the time at
which any Non-statutory Stock Option may be exercised in whole or in part.  The
acceleration of any Non-statutory Stock Option under the authority of this
paragraph shall create no right, expectation or reliance on the part of any
other Participant or that certain Participant regarding any other unaccelerated
Non-statutory Stock Options.  Unless determined otherwise by the Committee and
except in the event of the Participant's death or pursuant to a domestic
relations order, a Non-statutory Stock Option is not transferable and may be
exercisable in his lifetime only by the Participant to whom it is granted.  Upon
the death of a Participant, a Non-statutory Stock Option is transferable by will
or the laws of descent and distribution.

     (c) NSO Agreement.  The terms and conditions of any Non-statutory Stock
         --------------                                                     
Option granted shall be evidenced by an agreement (the "NSO Agreement") which
shall be subject to the terms and conditions of the Plan.

     (d) Termination of Employment or Service.   Unless otherwise determined by
         ------------------------------------                                  
the Committee, upon the termination of a Participant's employment or service for
any reason other than Disability, death or Termination for Cause, the
Participant's Non-statutory Stock Options shall be exercisable only as to those
shares that were immediately exercisable by the Participant at the date of
termination and only for a period of three months following termination.
Notwithstanding any provisions set forth herein or contained in any NSO
Agreement relating to 

                                      -6-
<PAGE>
 
an award of a Non-statutory Stock Option, in the event of termination of the
Participant's employment or service for Disability or death, all Non-statutory
Stock Options held by such Participant shall immediately vest and be exercisable
for one year after such termination of service, and, in the event of a
Termination for Cause, all rights under the Participant's Non-statutory Stock
Options shall expire immediately upon such Termination for Cause.

7.  INCENTIVE STOCK OPTIONS.
    ----------------------- 

     The Committee may, subject to the limitations of the Plan and the
availability of  shares reserved but unawarded under the Plan, from time to
time, grant Incentive Stock Options to Employees upon such terms and conditions
as the Committee may determine.  Incentive Stock Options granted pursuant to the
Plan shall be subject to the following terms and conditions:

     (a) Exercise Price.  The Exercise Price of each Incentive Stock Option
         --------------                                                    
shall be not less than 100% of the Fair Market Value of the Common Stock on the
Date of Grant.  However, if at the time an Incentive Stock Option is granted to
an Employee Participant, such Employee Participant owns Common Stock
representing more than 10% of the total combined voting securities of the
Holding Company (or, under Section 424(d) of the Code, is deemed to own Common
Stock representing more than 10% of the total combined voting power of all
classes of stock of the Holding Company, by reason of the ownership of such
classes of stock, directly or indirectly, by or for any brother, sister, spouse,
ancestor or lineal descendent of such Employee Participant, or by or for any
corporation, partnership, estate or trust of which such Employee Participant is
a shareholder, partner or beneficiary) ("10% Owner"), the Exercise Price per
share of Common Stock deliverable upon the exercise of each Incentive Stock
Option shall not be less than 110% of the Fair Market Value of the Common Stock
on the Date of Grant.   Shares may be purchased only upon payment of the full
Exercise Price or upon operation of an Alternate Option Payment Mechanism set
out in Section 11 hereof.

     (b) Amounts of Incentive Stock Options.  Incentive Stock Options may be
         ----------------------------------                                 
granted to any Employee in such amounts as determined by the Committee; provided
that the amount granted is consistent with the terms of Section 422 of the Code.
In the case of an Option intended to qualify as an Incentive Stock Option, the
aggregate Fair Market Value (determined as of the time the Option is granted) of
the Common Stock with respect to which Incentive Stock Options granted are
exercisable for the first time by the Employee Participant during any calendar
year (under all plans of the Employee Participant's employer corporation and its
parent and subsidiary corporations) shall not exceed $100,000.  The provisions
of this Section 7(b) shall be construed and applied in accordance with Section
422(d) of the Code and the regulations, if any, promulgated thereunder.  To the
extent an Award of an Incentive Stock Option under this Section 7 exceeds this
$100,000 limit, the portion of the Award in excess of such limit shall be deemed
a Non-statutory Stock Option.  The Committee shall have discretion to
redesignate Options granted as Incentive Stock Options as Non-Statutory Stock
Options.  Such Non-statutory Stock Options shall be subject to Section 6 hereof.

     (c) Terms of Incentive Stock Options.  The term during which each Incentive
         --------------------------------                                       
Stock Option may be exercised shall be determined by the Committee, but in no
event shall an 

                                      -7-
<PAGE>
 
Incentive Stock Option be exercisable in whole or in part more than 10 years
from the Date of Grant. If at the time an Incentive Stock Option is granted to
an Employee Participant who is a 10% Owner, the Incentive Stock Option granted
to such Employee Participant shall not be exercisable after the expiration of
five years from the Date of Grant. No Incentive Stock Option is transferable
except by will or the laws of descent and distribution and is exercisable in his
or her lifetime only by the Employee Participant to whom it is granted. The
designation of a beneficiary does not constitute a transfer.

     The Committee shall determine the date on which each Incentive Stock Option
shall become exercisable.  The shares comprising each installment of the
Incentive Stock Option may be purchased in whole or in part at any time during
the term of such Option after such installment becomes exercisable.  The
Committee may, in its sole discretion, accelerate the time at which any
Incentive Stock Option may be exercised in whole or in part.  The acceleration
of any Incentive Stock Option under the authority of this paragraph shall not
create a right, expectation or reliance on the part of any other Participant or
that certain Participant regarding any other unaccelerated Incentive Stock
Options.

     (d) ISO Agreement.  The terms and conditions of any Incentive Stock Option
         -------------                                                         
granted shall be evidenced by an agreement (the "ISO Agreement") which shall be
subject to the terms and conditions of the Plan.

     (e) Termination of Employment.  Unless otherwise determined by the
         -------------------------                                     
Committee, upon the termination of an Employee Participant's employment for any
reason other than Disability, death or Termination for Cause, the Employee
Participant's Incentive Stock Options shall be exercisable only as to those
shares that were immediately exercisable by the Participant at the date of
termination and only for a period of three months following termination.
Notwithstanding any provision set forth herein or contained in any ISO Agreement
relating to an award of an Incentive Stock Option, in the event of termination
of the Employee Participant's employment for Disability or death, all Incentive
Stock Options held by such Employee Participant shall immediately vest and be
exercisable for one year after such termination, and, in the event of
Termination for Cause, all rights under the Employee Participant's Incentive
Stock Options shall expire immediately upon termination.  No Incentive Stock
Option shall be eligible for treatment as an Incentive Stock Option in the event
such Incentive Stock Option is exercised more than three months following the
date of Participant's cessation of employment.  In no event shall an Incentive
Stock Option be exercisable beyond the expiration of the Incentive Stock Option
term.

     (f) Compliance with Code.  The Incentive Stock Options granted under this
         --------------------                                                 
Section 7 are intended to qualify as "incentive stock options" within the
meaning of Section 422 of the Code, but the Holding Company makes no warranty as
to the qualification of any Option as an incentive stock option within the
meaning of Section 422 of the Code.  All Options that do not so qualify shall be
treated as Non-statutory Stock Options.

                                      -8-

8.   LIMITED RIGHT.
     ------------- 

     Simultaneously with the grant of any Option to an Employee or Outside
Director, the Committee may grant a Limited Right with respect to all or some of
the shares covered by such Option.  Limited Rights granted under this Plan are
subject to the following terms and conditions:

     (a)  Terms of Rights.  In no event shall a Limited Right be exercisable in
          ---------------                                                      
whole or in part before the expiration of six months from the Date of Grant of
the Limited Right.  A Limited Right may be exercised only in the event of a
Change in Control.

     The Limited Right may be exercised only when the underlying Option is
eligible to be exercised, and only when the Fair Market Value of the underlying
shares on the day of exercise is greater than the Exercise Price of the
underlying Option.

     Upon exercise of a Limited Right, the underlying Option shall cease to be
exercisable.  Upon exercise or termination of an Option, any related Limited
Rights shall terminate.  The Limited Rights may be for no more than 100% of the
difference between the purchase price and the Fair Market Value of the Common
Stock subject to the underlying option.  The Limited Right is transferable only
when the underlying option is transferable and under the same conditions.

     (b)  Payment.  Upon exercise of a Limited Right, the holder shall promptly
          -------                                                              
receive from the Holding Company an amount of cash equal to the difference
between the Exercise Price of the underlying option and the Fair Market Value of
the Common Stock subject to the underlying Option on the date the Limited Right
is exercised, multiplied by the number of shares with respect to which such
Limited Right is exercised.  Payments shall be less any applicable tax
withholding as set forth in Section 16 hereof.

9.   STOCK AWARD.
     ----------- 

     The Committee may, subject to the limitations of the Plan, from time to
time, make an Award of shares of Common Stock to Employees and Outside Directors
("Stock Awards").  The Stock Awards shall be made subject to the following terms
and conditions:

     (a) Payment of the Stock Award.  The Stock Award may only be made in whole
         --------------------------                                            
shares of Common Stock.  Stock Awards may only be granted from shares reserved
under the Plan but unawarded at the time the new Stock Award is made.

     (b) Terms of the Stock Awards.  The Committee shall determine the dates on
         -------------------------                                             
which Stock Awards granted to a Participant shall vest and any specific
conditions or performance goals which must be satisfied prior to the vesting of
any installment or portion of the Stock Award.  Notwithstanding other paragraphs
in this Section 9, the Committee may, in its sole discretion, accelerate the
vesting of any Stock Award.  The acceleration of any Stock Award 

                                      -9-
<PAGE>
 
under the authority of this paragraph shall create no right, expectation or
reliance on the part of any other Participant or that certain Participant
regarding any other unaccelerated Stock Awards.

     (c) Stock Award Agreement. The terms and conditions of any Stock Award
         ---------------------                                             
shall be evidenced by an agreement (the "Stock Award Agreement") which such
Stock Award Agreement will be subject to the terms and conditions of the Plan.
Each Stock Award Agreement shall set forth:

               (i)  the period over which the Stock Award will vest;

               (ii) the performance goals, if any, which must be satisfied prior
                    to the vesting of any installment or portion of the Stock
                    Award.  The performance goals may be set by the Committee on
                    an individual level, for all Participants, for all Awards
                    made during a given period of time, or for all Awards for
                    indefinite periods;


     (d) Certification of Attainment of the Performance Goal.  No Stock Award or
         ---------------------------------------------------                    
portion thereof that is subject to a performance goal is to be distributed to an
Employee Participant until the Committee certifies that the underlying
performance goal has been achieved, or in the case of an Outside Director
Participant, until an independent third party presents a certification to the
Board of Directors that the underlying performance goal associated with a Stock
Award has been achieved.
 
     (e) Termination of Employment or Service.  Unless otherwise determined by
         ------------------------------------                                 
the Committee, upon the termination of a Participant's employment or service for
any reason other than Disability, death or Termination for Cause, the
Participant's unvested Stock Awards as of the date of termination shall be
forfeited and any rights the Participant had to such unvested Stock Awards shall
become null and void.  Notwithstanding any provisions set forth herein or
contained in any NSO Agreement relating to an award of a Non-statutory Stock
Option, in the event of termination of the Participant's service due to
Disability or death, all unvested Stock Awards held by such Participant,
including any portion of a Stock Award subject to a performance goal, shall
immediately vest and, in the event of the Participant's Termination for Cause,
the Participant's unvested Stock Awards as of the date of such termination shall
be forfeited and any rights the Participant had to such unvested Stock Awards
shall become null and void.

     (f) Non-Transferability.  Except to the extent permitted by the Code, the
         -------------------                                                  
rules promulgated under Section 16(b) of the Exchange Act or any successor
statutes or rules:

               (i)  The recipient of a Stock Award shall not sell, transfer,
                    assign, pledge, or   otherwise encumber shares subject to
                    the Stock Award until full vesting of such shares has
                    occurred.  For purposes of this section, the separation of
                    beneficial ownership and legal title through the use of any
                    "swap" transaction is deemed to be a prohibited encumbrance.

               (ii) Unless determined otherwise by the Committee and except in
                    the event of 

                                      -10-
<PAGE>
 
                    the Participant's death or pursuant to a domestic relations
                    order, a Stock Award is not transferable and may be earned
                    in his lifetime only by the Participant to whom it is
                    granted. Upon the death of a Participant, a Stock Award is
                    transferable by will or the laws of descent and
                    distribution. The designation of a beneficiary does not
                    constitute a transfer.

             (iii)  If a recipient of a Stock Award is subject to the
                    provisions of Section 16 of the Exchange Act, shares of
                    Common Stock subject to such Stock Award may not, without
                    the written consent of the Committee (which consent may be
                    given in the Stock Award Agreement), be sold or otherwise
                    disposed of within six months following the date of grant of
                    the Stock Award.


     (g) Accrual of Dividends.  Whenever shares of Common Stock underlying a
         --------------------                                               
Stock Award are distributed to a Participant or beneficiary thereof under the
Plan, such Participant or beneficiary shall also be entitled to receive, with
respect to each such share distributed, a payment equal to any cash dividends or
distributions (other than distributions in shares of Common Stock) and the
number of shares of Common Stock equal to any stock dividends, declared and paid
with respect to a share of the Common Stock if the record date for determining
shareholders entitled to receive such dividends falls between the date the
relevant Stock Award was granted and the date the relevant Stock Award or
installment thereof is distributed.  There shall also be distributed an
appropriate amount of net earnings, if any, of the Trust with respect to any
dividends paid out.

     (h) Voting of Stock Awards.  After a Stock Award has been granted, but for
         -----------------------                                               
which the shares covered by such Stock Award have not yet been earned and
distributed to the Participant pursuant to the Plan, the Participant shall be
entitled to direct the Trustee as to the voting of such shares of  Common Stock
which the Stock Award covers subject to the rules and procedures adopted by the
Committee for this purpose.  All shares of Common Stock held by the Trust as to
which Participants are not entitled to direct, or have not directed the voting,
shall be voted by the Trustee in the same proportion as the Common Stock covered
by Stock Awards which have been awarded is voted.

10.  PAYOUT ALTERNATIVES
     -------------------

     Payments due to a Participant upon the exercise or redemption of an Award,
may be made subject to the following terms and conditions:

     (a) Discretion of the Committee.  The Committee has the sole discretion to
         ---------------------------                                           
determine what form of payment (whether monetary, Common Stock, a combination of
payout alternatives or otherwise) it shall use in making distributions of
payments for all Awards.  If the Committee requests any or all Participants to
make an election as to form of distribution or payment, it shall not be
considered bound by the election.

                                      -11-
<PAGE>
 
     (b) Payment in the form of Common Stock.  Any shares of Common Stock
         -----------------------------------                             
tendered in satisfaction of an obligation arising under this Plan shall be
valued at the Fair Market Value of the Common Stock on the day preceding the
date of the issuance of such stock to the Participant.

11.  ALTERNATE OPTION PAYMENT MECHANISM
     ----------------------------------

     The Committee has sole discretion to determine what form of payment it will
accept for the exercise of an Option.  The Committee may indicate acceptable
forms in the ISO or NSO Agreement covering such Options or may reserve its
decision to the time of exercise.  No Option is to be considered exercised until
payment in full is accepted by the Committee or its agent.

     (a) Cash Payment.  The exercise price may be paid in cash or by certified
         ------------                                                         
check.

     (b) Borrowed Funds.  To the extent permitted by law, the Committee may
         --------------                                                    
permit all or a portion of the exercise price of an Option to be paid through
borrowed funds.

     (c)  Exchange of Common Stock.
          ------------------------ 

               (i)  The Committee may permit payment by the tendering of
                    previously acquired shares of Common Stock.  This includes
                    the use of "pyramiding transactions" whereby some number of
                    Options are exercised; then the shares gained through the
                    exercise are tendered back to the Holding Company as payment
                    for a greater number of Options.  This transaction may be
                    repeated as needed to exercise all of the Options available.

               (ii) Any shares of Common Stock tendered in payment of the
                    exercise price of an Option shall be valued at the Fair
                    Market Value of the Common Stock on the date prior to the
                    date of exercise.


12.  RIGHTS OF A SHAREHOLDER: NONTRANSFERABILITY.
     ------------------------------------------- 

     No Participant shall have any rights as a shareholder with respect to any
shares of Common Stock covered by an Option until the date of issuance of a
stock certificate for such shares.  Nothing in this Plan or in any Award granted
confers on any person any right to continue in the employ or service of the
Holding Company or its Affiliates or interferes in any way with the right of the
Holding Company or its Affiliates to terminate a Participant's services as an
officer or other employee at any time.

     Except as permitted under the Code (with respect to Incentive Stock
Options) and the rules promulgated pursuant to Section 16(b) of the Exchange Act
or any successor statutes or rules, no Award under the Plan shall be
transferable by the Participant other than by will or the laws of intestate
succession or pursuant to a domestic relations order or unless determined
otherwise by the Committee.

13.  AGREEMENT WITH GRANTEES.
     ----------------------- 

     Each Award will be evidenced by a written agreement(s) (whether
constituting an NSO Agreement, ISO Agreement, Stock Award Agreement or any
combination thereof), executed by the Participant and the Holding Company or its
Affiliates that describes the conditions for receiving the Awards including the
date of Award, the Exercise Price if any, the terms or other applicable periods,
and other terms and conditions as may be required or imposed by the Plan, the
Committee, or the Board of Directors, and may describe or specify tax law
considerations or applicable securities law considerations.

14.  DESIGNATION OF BENEFICIARY.
     -------------------------- 

     A Participant may, with the consent of the Committee, designate a person or
persons to receive, in the event of death, any Award to which the Participant
would then be entitled.  Such designation will be made upon forms supplied by
and delivered to the Holding Company and may be revoked in writing.  If a
Participant fails effectively to designate a beneficiary, then the Participant's
estate will be deemed to be the beneficiary.

15.  DILUTION AND OTHER ADJUSTMENTS.
     ------------------------------ 

     In the event of any change in the outstanding shares of Common Stock  by
reason of any stock dividend or split, recapitalization, merger, consolidation,
spin-off, reorganization, combination or exchange of shares, or other similar
corporate change, or other increase or decrease in such shares without receipt
or payment of consideration by the Holding Company, or in the event a capital
distribution is made, the Committee will make such adjustments to Awards to
prevent dilution, diminution or enlargement of the rights of the Participant, as
the Committee deems appropriate, including any or all of the following:

        (a)  adjustments in the aggregate number or kind of shares of Common
             Stock or other securities that may underlie future Awards under the
             Plan;

        (b)  adjustments in the aggregate number or kind of shares of Common
             Stock or other securities underlying Awards already made under the
             Plan;

        (c)  adjustments in the exercise price of outstanding Incentive and/or
             Non-statutory Stock Options, or any Limited Rights attached to such
             Options.

     Alternatively, the Committee could provide the participant with a cash
benefit for shares underlying vested, but unexercised options, in order to
achieve the aforementioned effect.  All awards under this Plan shall be binding
upon any successors or assigns of the Holding Company.

                                      -13-
<PAGE>
 
16.  TAX WITHHOLDING.
     --------------- 

     Awards under this Plan shall be subject to tax withholding to the extent
required by any governmental authority.  Any withholding shall comply with Rule
16b-3 or any amendment or successive rule.  Shares of Common Stock withheld to
pay for tax withholding amounts shall be valued at their Fair Market Value on
the date the Award is deemed taxable to the Participant.

17.  AMENDMENT OF THE PLAN.
     --------------------- 

     The Board of Directors may at any time, and from time to time, subject to
applicable rules and regulations, modify or amend the Plan, or any Award granted
under the Plan, in any respect, prospectively or retroactively; provided
however, that provisions governing grants of Incentive Stock Options, unless
permitted by the rules and regulations or staff pronouncements promulgated under
the Code shall be submitted for shareholder approval to the extent required by
such law, regulation or interpretation.

     Failure to ratify or approve amendments or modifications by shareholders
shall be effective only as to the specific amendment or modification requiring
such ratification.  Other provisions, sections, and subsections of this Plan
will remain in full force and effect.

     No such termination, modification or amendment may adversely affect the
rights of a Participant under an outstanding Award without the written
permission of such Participant.

18.  EFFECTIVE DATE OF PLAN.
     ---------------------- 

     The Plan shall become effective upon being presented to shareholders for
ratification for purposes of:  (i) obtaining preferential tax treatment for
Incentive Stock Options; and (ii) maintaining the listing of the Common Stock on
the Nasdaq National Market.  The failure to obtain shareholder ratification for
such purposes will not affect the validity of the Plan and the Options
thereunder, provided, however, that if the Plan is not ratified, the Plan shall
remain in full force and effect, and any Incentive Stock Options granted under
the Plan shall be deemed to be Non-statutory Stock Options.

19.  TERMINATION OF THE PLAN.
     ----------------------- 

     The right to grant Awards under the Plan will terminate upon the earlier
of: (i) ten (10) years after the Effective Date; (ii)  the issuance of a number
of shares of Common Stock pursuant to the exercise of Options or the
distribution of Stock Awards which together with the exercise of Limited Rights
is equivalent to the maximum number of shares reserved under the Plan as set
forth in Section 4.  The Board of Directors has the right to suspend or
terminate the Plan at any time, provided that no such action will, without the
consent of a Participant, adversely affect a Participant's vested rights under a
previously granted Award.

                                      -14-
<PAGE>
 
20.  APPLICABLE LAW
     --------------

     The Plan will be administered in accordance with the laws of the State of
Delaware and applicable federal law.

21.  COMPLIANCE WITH OTS CONVERSION REGULATIONS
     ------------------------------------------

      Notwithstanding any other provision contained in this Plan:

      (a)  unless the Plan is approved by a majority vote of the outstanding
           shares of the total votes eligible to be cast at a duly called
           meeting of stockholders to consider the Plan, as required by 12
           C.F.R. (S) 563b.3(g)(4)(vii), the Plan shall not become effective or
           implemented prior to one year from the date of the Bank's
           reorganization into the stock holding company structure;

      (b)  no Award granted prior to one year from the date of the Bank's
           reorganization into the stock holding company structure shall become
           vested or exercisable at a rate in excess of 20% per year of the
           total number of Stock Awards or Options (whichever may be the case)
           granted to such Participant, provided, that Awards shall become fully
           vested or immediately exercisable in the event of a Participant's
           termination of service due to death or Disability;

      (c)  no Award granted to any individual employee prior to one year from
           the date of the Bank's reorganization into the stock holding company
           structure may exceed 25% of the total amount of Awards which may be
           granted under the Plan;

      (d)  no Award granted to any individual Outside Director prior to one year
           from the date of the Bank's reorganization into the stock holding
           company structure may exceed 5% of the total amount of Awards which
           may be granted under the Plan; and

      (e)  the aggregate amount of Awards granted to all Outside Directors prior
           to one year from the date of the Bank's reorganization into the stock
           holding company structure may not exceed 30% of the total amount of
           Awards which may be granted under the Plan.

 
22.  DELEGATION OF AUTHORITY
     -----------------------

     The Committee may delegate all authority for: the determination of forms of
payment to be made by or received by the Plan; the execution of Award
agreements; the determination of Fair Market Value; and the determination of all
other aspects of administration of the Plan to the executive officer(s) of the
Holding Company or the Bank.  The Committee may rely on the descriptions,
representations, reports and estimates provided to it by the management of the
Holding Company or the Bank for determinations to be made pursuant to the Plan,
including the attainment of performance goals.  However, only the Committee or a
portion of the Committee may certify the attainment of a performance goal.

ITEM 20. INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
In accordance with the General Corporation Law of the State of Delaware (being
Chapter 1 of Title 8 of the Delaware Code), Articles 10 and 11 of First Source
Bancorp, Inc.'s Certificate of Incorporation provide as follows:
 
TENTH:
 
A. Each person who was or is made a party or is threatened to be made a party
to or is otherwise involved in any action, suit or proceeding, whether civil,
criminal, administrative or investigative (hereinafter a "proceeding"), by
reason of the fact that he or she is or was a Director or an Officer of the
Corporation or is or was serving at the request of the Corporation as a
Director, Officer, employee or agent of another corporation or of a
partnership, joint venture, trust or other enterprise, including service with
respect to an employee benefit plan (hereinafter an "indemnitee"), whether the
basis of such proceeding is alleged action in an official capacity as a
Director, Officer, employee or agent, or in any other capacity while serving
as a Director, Officer, employee or agent, shall be indemnified and held
harmless by the Corporation to the fullest extent authorized by the Delaware
General Corporation Law, as the same exists or may hereafter be amended (but,
in the case of any such amendment, only to the extent that such amendment
permits the Corporation to provide broader indemnification rights than such
law permitted the Corporation to provide prior to such amendment), against all
expense, liability and loss (including attorneys' fees, judgments, fines,
ERISA excise taxes or penalties and amounts paid in settlement) reasonably
incurred or suffered by such indemnitee in connection therewith; provided,
however, that, except as provided in Section C hereof with respect to
proceedings to enforce rights to indemnification, the Corporation shall
indemnify any such indemnitee in connection with a proceeding (or part
thereof) initiated by such indemnitee only if such proceeding (or part
thereof) was authorized by the Board of Directors of the Corporation.
 
B. The right to indemnification conferred in Section A of this Article TENTH
shall include the right to be paid by the Corporation the expenses incurred in
defending any such proceeding in advance of its final disposition (hereinafter
an "advancement of expenses"); provided, however, that, if the Delaware
General Corporation Law requires, an advancement of expenses incurred by an
indemnitee in his or her capacity as a Director or Officer (and not in any
other capacity in which service was or is rendered by such indemnitee,
including, without limitation, services to an employee benefit plan) shall be
made only upon delivery to the Corporation of an undertaking (hereinafter an
"undertaking"), by or on behalf of such indemnitee, to repay all amounts so
advanced if it shall ultimately be determined by final judicial decision from
which there is no further right to appeal (hereinafter a "final adjudication")
that such indemnitee is not entitled to be indemnified for such expenses under
this Section or otherwise. The rights to indemnification and to the
advancement of expenses conferred in Sections A and B of this Article TENTH
shall be contract rights and such rights shall continue as to an indemnitee
who has ceased to be a Director, Officer, employee or agent and shall inure to
the benefit of the indemnitee's heirs, executors and administrators.
 
C. If a claim under Section A or B of this Article TENTH is not paid in full
by the Corporation within sixty days after a written claim has been received
by the Corporation, except in the case of a claim for an advancement of
expenses, in which case the applicable period shall be twenty days, the
indemnitee may at any time thereafter bring suit against the Corporation to
recover the unpaid amount of the claim. If successful in whole or in part in
any such suit, or in a suit brought by the Corporation to recover an
advancement of expenses pursuant to the terms of an undertaking, the
indemnitee shall be entitled to be paid also the expenses of prosecuting or
defending such suit. In (i) any suit brought by the indemnitee to enforce a
right to indemnification hereunder (but not in a suit brought by the
indemnitee to enforce a right to an advancement of expenses) it shall be a
defense that, and (ii) in any suit by the Corporation to recover an
advancement of expenses pursuant to the terms of an undertaking the
Corporation shall be entitled to recover such expenses upon a final
adjudication that, the indemnitee has not
 
                                     II-1
<PAGE>
 
met any applicable standard for indemnification set forth in the Delaware
General Corporation Law. Neither the failure of the Corporation (including its
Board of Directors, independent legal counsel, or its stockholders) to have
made a determination prior to the commencement of such suit that
indemnification of the indemnitee is proper in the circumstances because the
indemnitee has met the applicable standard of conduct set forth in the
Delaware General Corporation Law, nor an actual determination by the
Corporation (including its Board of Directors, independent legal counsel, or
its stockholders) that the indemnitee has not met such applicable standard of
conduct, shall create a presumption that the indemnitee has not met the
applicable standard of conduct or, in the case of such a suit brought by the
indemnitee, be a defense to such suit. In any suit brought by the indemnitee
to enforce a right to indemnification or to an advancement of expenses
hereunder, or by the Corporation to recover an advancement of expenses
pursuant to the terms of an undertaking, the burden of proving that the
indemnitee is not entitled to be indemnified, or to such advancement of
expenses under this Article TENTH or otherwise shall be on the Corporation.
 
D. The rights to indemnification and to the advancement of expenses conferred
in this Article TENTH shall not be exclusive of any other right which any
person may have or hereafter acquire under any statute, the Corporation's
Certificate of Incorporation, Bylaws, agreement, vote of stockholders or
Disinterested Directors or otherwise.
 
E. The Corporation may maintain insurance, at its expense, to protect itself
and any Director, Officer, employee or agent of the Corporation or subsidiary
or Affiliate or another corporation, partnership, joint venture, trust or
other enterprise against any expense, liability or loss, whether or not the
Corporation would have the power to indemnify such person against such
expense, liability or loss under the Delaware General Corporation Law.
 
F. The Corporation may, to the extent authorized from time to time by the
Board of Directors, grant rights to indemnification and to the advancement of
expenses to any employee or agent of the Corporation to the fullest extent of
the provisions of this Article TENTH with respect to the indemnification and
advancement of expenses of Directors and Officers of the Corporation.
 
ELEVENTH:
 
A Director of this Corporation shall not be personally liable to the
Corporation or its stockholders for monetary damages for breach of fiduciary
duty as a Director, except for liability: (i) for any breach of the Director's
duty of loyalty to the Corporation or its stockholders, (ii) for acts or
omissions not in good faith or which involve intentional misconduct or a
knowing violation of law, (iii) under Section 174 of the Delaware General
Corporation Law, or (iv) for any transaction from which the Director derived
an improper personal benefit. If the Delaware General Corporation Law is
amended to authorize corporate action further eliminating or limiting the
personal liability of Directors, then the liability of a Director of the
Corporation shall be eliminated or limited to the fullest extent permitted by
the Delaware General Corporation Law, as so amended.
 
Any repeal or modification of the foregoing paragraph by the stockholders of
the Corporation shall not adversely affect any right or protection of a
Director of the Corporation existing at the time of such repeal or
modification.

ITEM 22. UNDERTAKINGS.
 
  The undersigned Registrants hereby undertake:
 
  (1) To file, during any period in which offers or sales are being made, a
      post-effective amendment to this Registration Statement:
 
    (i) To include any Prospectus required by Section 10(a)(3) of the
        Securities Act of 1933;
 
    (ii) To reflect in the Prospectus any facts or events arising after the
         effective date of the Registration Statement (or the most recent
         post-effective amendment thereof) which, individually or in the
 
                                     II-3
<PAGE>
 
       aggregate, represent a fundamental change in the information set
       forth in the Registration Statement. Notwithstanding the foregoing,
       any increase or decrease in volume of securities offered (if the
       total dollar value of securities offered would not exceed that which
       was registered) and any deviation from the low or high end of the
       estimated maximum offering range may be reflected in the form of
       prospectus filed with the Commission pursuant to Rule 424(b) if, in
       the aggregate, the changes in volume and price represent no more than
       a 20 percent change in the maximum aggregate offering price set forth
       in the "Calculation of Registration Fee" table in the effective
       registration statement;
 
    (iii) To include any material information with respect to the plan of
          distribution not previously disclosed in the Registration
          Statement or any material change to such information in the
          Registration Statement;
 
  (2) That, for the purpose of determining any liability under the Securities
      Act of 1933, each such post-effective amendment shall be deemed to be a
      new Registration Statement relating to the securities offered therein,
      and the offering of such securities at that time shall be deemed to be
      the initial bona fide offering thereof.
 
  (3) To remove from registration by means of a post-effective amendment any
      of the securities being registered which remain unsold at the
      termination of the Offering.
 
  Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of the
Registrants pursuant to the foregoing provisions, or otherwise, the
registrants have been advised that in the opinion of the Securities and
Exchange Commission such indemnification is against public policy as expressed
in the Act and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by the
registrants of expenses incurred or paid by a director, officer or controlling
person of the Registrants in the successful defense of any action, suit or
proceeding) is asserted by such trustee, officer or controlling person in
connection with the securities being registered, the Registrants will, unless
in the opinion of their counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in the Act
and will be governed by the final adjudication of such issue.
 
  The undersigned registrants hereby undertake to respond to requests for
information that is incorporated by reference into the prospectus pursuant to
Items 4, 10(b), 11, or 13 of this Form, within one business day of receipt of
such request, and to send the incorporated documents by first class mail or
other equally prompt means. This includes information contained in documents
filed subsequent to the effective date of the registration statement through
the date of responding to the request.
 
  The undersigned registrants hereby undertake to supply by means of a post-
effective amendment all information concerning a transaction, and the company
being acquired involved therein, that was not the subject of and included in
the registration statement when it became effective.

RE:  First Source Bancorp, Inc. Registration Statement on Form S-4

Dear  Ladies and Gentlemen:

We have acted as special counsel to First Source Bancorp, Inc., a Delaware
corporation (the "Company"), in connection with the issuance and sale by the
Company of an aggregate of up to 13,625,152 shares (the "Shares") of common
stock, par value $0.01 per share (the "Common Stock"), of the Company pursuant
to an Agreement and Plan of Merger, dated as of July 9, 1998 (the "Merger
Agreement"), by and between the Company and Pulse Bancorp, Inc., a New Jersey
corporation.

This opinion is delivered in accordance with the requirements of Item 601(b)(5)
of Regulation S-K under the Securities Act of 1933, as amended.

In connection with this opinion, we have examined and are familiar with
originals or copies, certified or otherwise indicated to our satisfaction, of
(i) the Registration Statement of the Company on Form S-4 filed with the
Securities and Exchange Commission (the "Commission") on the date hereof (the
"Registration Statement");  (ii) the form of certificates to be used to
represent the Shares, (iii) the Certificate of Incorporation and By-Laws of the
Company, as amended to date; (iv) resolutions adopted by the Board of Directors
of the Company relating to the Merger Agreement and the issuance of Shares; and
(vi) such other documents as we have deemed necessary or appropriate as a basis
for the opinion set forth below.

In our examination, we have assumed the genuineness of all signatures, the legal
capacity of all natural persons, the authenticity of all documents submitted to
us as originals, the conformity to original documents of all documents submitted
to us as certified, conformed or photostatic

copies, and the authenticity of originals of such copies. As to any other facts
material to this opinion which we did not independently establish or verify, we
have relied upon statements or representations of officers and other
representatives of the Company and others.

The opinion is limited in all respects to matters of Federal law and the law of
the State of Delaware, and we express no opinion as to the laws of any other
jurisdiction.

Based upon the foregoing and assuming the due execution and delivery of
certificates representing the Shares in the form examined by us, we are of the
opinion that the Shares to be issued by the Company pursuant to the Merger
Agreement, when issued in accordance with the terms of the Merger Agreement,
will be duly authorized, validly issued, fully paid and nonassessable.

We hereby consent to the filing of this opinion with the Commission as Exhibit 5
to the Registration Statement.  We also consent to the reference to our firm
under the caption "Legal Opinions" in the Registration Statement.  In giving
such consent we do not thereby admit that we are in the category of persons
whose consent is required under Section 7 of the Act.


Very truly yours,

/s/ Patton Boggs LLP

Dear Ladies and Gentlemen:



We have acted as counsel to First Source Bancorp, Inc., a Delaware corporation
("FIRST SOURCE") in connection with the proposed merger of Pulse Bancorp, Inc.,
a New Jersey corporation ("PULSE"), with and into FIRST SOURCE (the "Merger")
and the merger of Pulse Savings Bank ("PULSE BANK"), a wholly owned subsidiary
of PULSE with and into First Savings Bank SLA ("FIRST SAVINGS"), a wholly owned
subsidiary of FIRST SOURCE (the "Bank Merger") immediately after and following
the Merger, pursuant to: (i) the terms of the Agreement and Plan of Merger dated
as of July 9, 1998 (the "Merger Agreement") by and among FIRST SOURCE and PULSE;
and (ii) the terms of the Subsidiary Agreement and Plan of Merger (the "Bank
Merger Agreement") by and among FIRST SAVINGS and PULSE BANK, each as described
in the Registration Statement on Form S-4 filed by FIRST SOURCE with the
Securities and Exchange Commission (the "Registration Statement").  All
capitalized terms, unless otherwise specified, have the meaning assigned to them
in the Merger Agreement.

For purposes of such examination, we have assumed the genuineness of all
signatures, the legal capacity of natural persons and the authenticity of all
documents submitted to us as relevant to this opinion, and we have relied upon
the documents referred to above (the "Documents"). We have assumed that all
parties had the corporate power and authority to enter into and perform all
obligations thereunder, and we have also assumed the due authorization by all
requisite corporate actions, the due execution and delivery and the validity and
binding effect and enforceability of such Documents. We have made investigations
of such matters of law and fact as we have considered necessary or appropriate
for this opinion. Our opinion is based on the assumption that there are no
agreements or understandings with
<PAGE>

respect to the transactions contemplated in the Documents other than those
contained in the Documents.  Furthermore, our opinion is based on the assumption
that all parties to the Documents will comply with the terms thereof, including
all tax reporting requirements contained therein.

We hereby confirm that the discussions described under the captions "Certain
Federal Income Tax Consequences of the Merger" in the Prospectus that is part of
the Registration Statement on Form S-4 filed by the Company with the Securities
and Exchange Commission on November 3, 1998, as amended, are a fair and accurate
summary of the matters addressed therein. Capitalized terms used herein but not
defined have the meanings as provided in the Merger Agreement.

We hereby consent to the use of our name under the caption "Federal Income Tax
Consequences of the Merger" in the Prospectus.   In giving the foregoing
consent, we do not thereby admit we come within the category of Persons whose
consent is required under Section 7 of the Securities Act of 1933, as amended,
or the rules and regulations of the Securities and Exchange Commission
thereunder.

The opinions set forth herein are based upon the existing provisions of the Code
and Treasury regulations issued or proposed thereunder, published Revenue
Rulings and releases of the Internal Revenue Service and existing case law, any
of which could be changed at any time.  Any such changes may be retroactive in
application and could modify the legal conclusions upon which such opinions are
based.  The opinions expressed herein are limited as described above, and we do
not express an opinion on any other legal or income tax aspect of the
transactions contemplated by the Documents.

In rendering the foregoing opinions, we express no opinion as to the laws of any
jurisdiction other than the federal income tax laws of the United States.  This
opinion is rendered as of the date hereof and we undertake no obligation to
update this opinion or advise you of changes in the event there is any change in
legal authorities, facts, assumptions or Documents on which this opinion is
based (including the taking of any action by any party to the Documents pursuant
to any opinion of counsel or a waiver) or any inaccuracy in any of the
representations, warranties or assumptions upon which we have relied in
rendering this opinion, unless we are specifically engaged to do so.  This
opinion is not binding on the Internal Revenue Service and there can be no
assurance, and none is hereby given, that the Internal Revenue Service will not
take a contrary position to one or more of the positions reflected in the
foregoing opinions, or that our opinion will be upheld by the courts if
challenged by the Internal Revenue Service.  This opinion may not be relied on
in connection with any transactions other than the transactions contemplated
herein.


Sincerely,


/s/ Patton Boggs LLP
