To Our Stockholders:
   
  We are pleased to invite you to attend a Special Meeting of Stockholders of

  At the Special Meeting, you will be asked to consider and vote on a proposal
to approve the Agreement and Plan of Merger, dated February 27, 1997, as
amended by Amendment No. 1 dated May 27, 1997, between Collective Bancorp and

merged with and into Summit Bancorp (the "Merger"). You will also be asked to
approve in advance any adjournment of the Special Meeting which may be
necessary to solicit additional proxies to approve the Merger Agreement.     
 
  The Merger Agreement provides that shares of Collective Bancorp common stock
("Collective Common") outstanding at the effective time of the Merger will be
converted into the right to receive whole shares of Summit Bancorp Common Stock

Summit Common to Collective Common of .895, all as more fully described in the
accompanying Proxy Statement-Prospectus. Completion of the Merger is subject to
certain conditions, including the approval of the Merger Agreement by the
stockholders of Collective Bancorp at this Special Meeting.
 
  The Board of Directors of Collective has carefully considered and approved
the Merger Agreement and believes that the Merger is in the best interests of
Collective Bancorp and its stockholders. ACCORDINGLY, YOUR BOARD OF DIRECTORS
UNANIMOUSLY RECOMMENDS THAT YOU VOTE FOR APPROVAL OF THE MERGER AGREEMENT AND
FOR THE PROPOSAL TO APPROVE AN ADJOURNMENT OF THE SPECIAL MEETING FOR THE
PURPOSE OF SOLICITING ADDITIONAL PROXIES, IF NECESSARY.
   
  YOUR VOTE IS IMPORTANT. Whether or not you plan to attend the Special
Meeting, please complete, sign and return the enclosed proxy promptly to assure
that your shares will be voted at the Special Meeting. On behalf of your Board
of Directors, I urge you to vote FOR approval of the Merger Agreement.     
 
  Thank you for your continued support.
 
                                         Sincerely,

REQUESTED TO SIGN, DATE AND RETURN THE ENCLOSED PROXY CARD WITHOUT DELAY IN
THE ENCLOSED POSTAGE-PAID ENVELOPE. ANY PROXY GIVEN BY A STOCKHOLDER MAY BE

  This Proxy Statement-Prospectus is being furnished to the holders of Common
Stock, par value $.01 per share ("Collective Common"), of Collective Bancorp,
Inc., a Delaware corporation and unitary savings and loan holding company
("Collective"), in connection with the solicitation of proxies by the Board of

to an Agreement and Plan of Merger, dated February 27, 1997, as amended by
Amendment No. 1 dated May 27, 1997 ("Merger Agreement"). In the Merger,
outstanding shares of Collective Common held by each Collective stockholder at
the Effective Time (as defined herein) will be converted into the right to
receive whole shares of Summit Common and cash in lieu of any fractional
shares of Summit Common resulting from the conversion ("Cash In Lieu Amount"),
based on an exchange ratio of Summit Common to Collective Common of .895 (the
"Exchange Ratio"), adjusted, if necessary, in accordance with certain anti-

herein as the "Merger Consideration").     
   
  This Proxy Statement-Prospectus constitutes (1) the Proxy Statement of
Collective relating to the solicitation of proxies by the Collective Board for
use at the Special Meeting to be held for the purpose of considering and
voting upon (a) a proposal to approve the Merger Agreement and the
transactions contemplated thereby and (b) a proposal to approve in advance an
adjournment of the Special Meeting in order to permit further solicitation of
proxies by Collective if insufficient shares are present at the scheduled date
and time of the Special Meeting to constitute a quorum or to approve the
Merger Agreement (the "Adjournment Proposal"), and (2) the Prospectus of
Summit with respect to the Summit Common to be issued in the Merger.
Consummation of the Merger is subject to various conditions, including the
approvals (collectively, the "Required Approvals") of the stockholders of
Collective and the Board of Governors of the Federal Reserve System ("Federal
Reserve Board").     
   
  Summit Common is traded on the New York Stock Exchange ("NYSE") and

respectively, on February 27, 1997 (the last trading day prior to the public
announcement of the Merger), and were $49.38 and $43.00, respectively, on May
30, 1997.

                                 THE COMPANIES
 
SUMMIT BANCORP.
 
  Summit Bancorp., a New Jersey corporation and registered bank holding company
with its principal executive offices at 301 Carnegie Center, Princeton, New
Jersey, through its wholly-owned subsidiary banks, Summit Bank (Hackensack,
NJ), Summit Bank (Bethlehem, PA) and the Bank of Mid-Jersey, operated 385

interest bearing deposit accounts, make business, real estate, personal and

and insurance and nondeposit investment products and services. In addition,
Summit owns subsidiaries that are engaged in discount brokerage, commercial
finance lending, lease financing and reinsuring credit life and disability
insurance policies related to consumer loans made by the subsidiary banks.
 
COLLECTIVE BANCORP, INC.
   
  Collective Bancorp, Inc., a Delaware corporation and unitary savings and loan
holding company with its principal executive offices at 716 West White Horse
Pike, Cologne, New Jersey, through its wholly-owned subsidiary savings bank,
Collective Bank ("Collective Bank"), operated, as of March 31, 1997, 82 branch
offices located in New Jersey. Collective's telephone number is (609) 625-1110.
Collective Bank is principally engaged in the business of attracting deposits
from the general public and using those deposits, together with borrowings and
other funds, to originate loans secured by real estate, to purchase mortgage
backed securities and, to a lesser extent, to originate various types of
consumer and commercial loans and to make other investments. In addition,
Collective Bank owns subsidiaries that are engaged in securities brokerage,
insurance agency and mortgage lending activities.     
 
                           COLLECTIVE SPECIAL MEETING
 
TIME, DATE, PLACE AND PURPOSE
   
  The Special Meeting will be held on July 16, 1997 at 10:00 a.m. (local time),
at the Ram's Head Inn, 9 West White Horse Pike (U.S. Highway 30), Absecon, New
Jersey, to consider and vote upon (1) a proposal to approve the Merger
Agreement and the transactions contemplated thereby, and (2) a proposal to
approve the Adjournment Proposal. A copy of the Merger Agreement is attached
hereto as Appendix A.     
 
RECORD DATE, VOTE REQUIRED
   
  The record date ("Record Date") for determining Collective stockholders
entitled to notice of and to vote at the Special Meeting is May 30, 1997. The
presence, in person or by proxy, of at least a majority of the 20,458,919
shares of Collective Common outstanding on the Record Date is necessary to
constitute a quorum at the Special Meeting. Assuming a quorum is present, an
affirmative vote of a majority of the shares outstanding and entitled to vote
at the Special Meeting is necessary to approve the Merger Agreement. In the
event a quorum     
 
                                       1
<PAGE>
 
is not present or there are insufficient votes to approve any proposal, the
Special Meeting may be adjourned from time to time by a majority of those
present in person or by proxy in order to permit, as appropriate, further
solicitation of proxies by the Collective Board.
 
                      STOCK HELD BY COLLECTIVE AFFILIATES
   
  The directors and executive officers of Collective and their affiliates
beneficially owned, as of the Record Date, 1,813,390 shares of Collective
Common (such total including all shares of Collective Common that could be
purchased by such persons pursuant to stock options outstanding on such date),
representing approximately 8.8% of the outstanding shares of Collective Common
(assuming for purposes of calculating this percentage that all shares of
Collective Common that could be purchased by directors, executive officers and
their affiliates pursuant to stock options outstanding on the Record Date were
issued and outstanding on such date). The directors and executive officers of
Collective have indicated that they intend to vote shares of Collective Common
over which they hold voting powers in favor of the proposal to approve the
Merger Agreement and in favor of the Adjournment Proposal.     
   
  Summit beneficially owns 163,700 shares of Collective Common, which
represents .8% of the outstanding shares of Collective Common, and intends to
vote these shares in favor of the proposal to approve the Merger Agreement and
in favor of the Adjournment Proposal.     
   
  Also, by virtue of holding the Collective Option (as defined herein), Summit
could be deemed to be the beneficial owner of an additional 4,067,424 shares of
Collective Common. Combined, the 163,700 shares beneficially owned and the
4,067,424 shares deemed beneficially owned by Summit represent approximately
17.3% of Collective Common outstanding on the Record Date (assuming for
purposes of calculating this percentage that the shares represented by the
Collective Option were issued and outstanding on such date). However, the
Collective Option is not presently exercisable and the Collective Common
represented thereby has not been issued, is not outstanding and cannot be
voted.     
 
                                   THE MERGER
 
EFFECTIVE TIME
   
  The Merger will become effective at the time and on the date ("Effective
Time") specified in the Certificate of Merger to be filed pursuant to the New
Jersey Business Corporation Act with the Secretary of State of the State of New
Jersey ("New Jersey Certificate") following the closing of the Merger, or, if
filed later than the effective time and date set forth in New Jersey
Certificate, the date the Certificate of Merger to be filed pursuant to the
Delaware General Corporation Law is filed with the Secretary of State of the
State of Delaware ("Delaware Certificate"). If the Merger is approved by
Collective stockholders, subject to the satisfaction or waiver of certain other
conditions set forth in the Merger Agreement, it is currently contemplated that
the Effective Time will occur during the third calendar quarter of 1997. At the
Effective Time, Collective will be merged with and into Summit. See "THE
MERGER--Closing and Effective Time."     
 
CONVERSION OF COLLECTIVE COMMON
   
  At the Effective Time, outstanding shares of Collective Common held by each
Collective stockholder, other than shares of Collective Common beneficially
owned by Summit or a subsidiary of Summit (other than shares of Collective
Common held as a result of debts previously contracted), if any, shares of
Collective Common beneficially owned by Collective or a subsidiary of
Collective (other than shares of Collective Common held as a result of debts
previously contracted), if any, and shares held in the treasury of Collective,
if any, will be converted into and represent the right to receive the Merger
Consideration. Within 7 days of the receipt of an accurate and complete list of
all holders of record of Collective Common as of the Effective Time by First
Chicago Trust Company of New York, or another entity reasonably satisfactory to
Collective, acting as the exchange agent for the Merger ("Exchange Agent"),
from Collective, each holder of record of Collective Common will be sent by the
Exchange Agent information regarding, and materials to be used in, the exchange
    
                                       2
<PAGE>
 
   
of Collective Common for the Merger Consideration. Within 7 days of the later
to occur of the receipt of a final stockholder list from Collective by the
Exchange Agent or the receipt by the Exchange Agent of complete exchange
materials from a Collective stockholder, the Collective stockholder will be
sent, in exchange for all certificates representing their Collective Common
("Collective Common Certificates"), one certificate representing the whole
shares of Summit Common into which their Collective Common has been converted
("Summit Common Certificate") and, to the extent entitled thereto, a check
representing a Cash In Lieu Amount. Such exchange period may be extended 5
business days by the Exchange Agent to permit it to satisfy its obligations
under the Internal Revenue Code of 1986, as amended (the "Code"), with respect
to reporting of dividend income.     
 
CONVERSION OF COLLECTIVE STOCK OPTIONS
   
  Each stock option relating to Collective Common ("Original Option")
outstanding at the Effective Time and granted to a director or employee
pursuant to the Collective Federal Savings and Loan Association Stock Option
Plan (the "Stock Option Plan") or the Collective Bancorp, Inc. Incentive Stock
Option Plan (the "Incentive Plan") (collectively, the "Collective Option
Plans"), will be converted automatically at the Effective Time into an option
to purchase Summit Common ("New Option"). All Original Options granted under
the Incentive Plan, whether or not exercisable immediately prior to the
Effective Time, will be converted pursuant to the terms of the Incentive Plan
into a New Option that is immediately exercisable after the Effective Time.
Subject to the adjustment in exercise price and number of shares described
below, the New Options will continue to be governed by the terms of the
Collective Option Plan and stock option agreement ("Grant Agreement") pursuant
to which the corresponding Original Option was granted, including terms and
provisions administering exercises. The number of shares of Summit Common
subject to the New Options and the exercise price of the New Options will be
adjusted as provided in the Merger Agreement based on the Exchange Ratio. See
"THE MERGER--Conversion of Collective Stock Options."     
 
RECOMMENDATION OF COLLECTIVE BOARD
 
  The Collective Board unanimously recommends that Collective stockholders vote
to approve the Merger Agreement and the Adjournment Proposal. See "THE MERGER--
Recommendation of Collective Board."
 
OPINION OF COLLECTIVE'S FINANCIAL ADVISOR
 
  Collective engaged Merrill Lynch & Co. ("Merrill Lynch") to act as financial
advisor in connection with the sale of Collective and to render its opinion to
the Collective Board as to whether the Exchange Ratio is fair, from a financial
point of view, to the stockholders of Collective. Merrill Lynch has delivered
to Collective an opinion dated as of the date of this Proxy Statement-
Prospectus stating that, as of such date, based on the review and assumptions
and subject to the limitations described therein, the Exchange Ratio is fair,
from a financial point of view, to Collective's stockholders. A copy of Merrill
Lynch's opinion is attached as Appendix B to this Proxy Statement-Prospectus
and should be read in its entirety. See "THE MERGER--Opinion of Collective's
Financial Advisor."
 
DISSENTERS' RIGHTS
 
  Under the Delaware General Corporation Law, there are no dissenters' rights
of appraisal available to holders of Collective Common in connection with the
Merger. See "THE MERGER--No Dissenters' Rights."
 
ACCOUNTING TREATMENT
 
  It is anticipated that the Merger, when consummated, will be accounted for as
a pooling-of-interests. See "THE MERGER--Accounting Treatment."
 
FEDERAL INCOME TAX CONSEQUENCES
 
  Thompson Coburn, Summit's special counsel, has delivered its opinion to the
effect that, assuming the Merger occurs in accordance with the Merger Agreement
and conditioned on the accuracy of certain
 
                                       3
<PAGE>
 
representations made by Summit and Collective and certain stockholders of
Collective, the Merger will constitute a "reorganization" within the meaning of
Section 368 of the Code for federal income tax purposes and that, accordingly,
no gain or loss will be recognized by Collective stockholders who exchange
their shares of Collective Common solely for shares of Summit Common in the
Merger, except with respect to any Cash In Lieu Amount received. Each
Collective stockholder is urged to consult his or her tax advisor to determine
the specific tax consequences of the Merger to such stockholder, including the
applicability of various state, local, and foreign tax laws. See "THE MERGER--
Certain Federal Income Tax Consequences of the Merger."
 
REGULATORY APPROVALS
   
  Consummation of the Merger requires, and is conditioned upon receipt of,
approval by the Federal Reserve Board which was received on May 29, 1997. See
"THE MERGER--Regulatory Approvals."     
 
CONDITIONS OF THE MERGER
   
  Consummation of the Merger is additionally subject, among other things, to
(i) the approval of the Merger Agreement by the requisite vote of the
Collective stockholders; (ii) the expiration of any waiting period required in
connection with a regulatory approval; (iii) continued effectiveness of the
registration statement; (iv) receipt by Summit and Collective of the opinion of
Thompson Coburn as to certain federal income tax consequences of the Merger;
(v) the NYSE having indicated that the shares of Summit Common to be issued in
the Merger are to be listed on the NYSE subject to official notice of issuance;
(vi) the absence of any material litigation; (vii) the absence of regulatory
agreements relating to the respective parties; (viii) the receipt by Summit of
agreements relating to resales of Summit Common ("Affiliate Agreements") from a
sufficient number of persons deemed to be "affiliates" of Collective
("Collective Affiliates") to permit pooling-of-interests accounting treatment
for the Merger; (ix) the receipt by Summit of a letter from KPMG Peat Marwick
LLP to the effect that the Merger will qualify for pooling-of-interests
accounting treatment and (x) the delivery of officers' certificates by
Collective and Summit. Certain of the foregoing conditions may be waived by the
party for whose benefit the condition was included. However, the Merger will
not be consummated without the receipt of all Required Approvals. See "THE
MERGER--The Merger Agreement--Conditions to the Merger, Termination."     
 
TERMINATION
   
  The Merger Agreement may be terminated by mutual consent of the Summit Board
and the Collective Board. The Merger Agreement may also be terminated by either
the Summit Board or the Collective Board if the conditions precedent to,
respectively, Summit's or Collective's obligations to close under the Merger
Agreement have not been met. Further, the Merger Agreement may be terminated by
either the Summit Board or the Collective Board if (i) the stockholders of
Collective have failed to approve the Merger; (ii) a material breach by the
other party of a warranty or representation or covenant has occurred and not
been cured or is not capable of being cured (after 30 days notice thereof has
been given and provided that the terminating party is not in material breach of
any representation, warranty, covenant or other agreement); or (iii) the
Closing is not consummated on or before January 1, 1998.     
 
INTERESTS OF CERTAIN PERSONS IN THE MERGER
   
  Directors and executive officers of Collective have interests in the Merger
that are in addition to their interests as stockholders of Collective. These
interests include: (1) the indemnification of directors and executive officers
of Collective against certain claims that may arise after the Effective Time
based on services provided to Collective or any subsidiary of Collective prior
to the Effective Time; (2) Summit's covenant to use its best efforts to
purchase insurance for six years after the Effective Time, subject to a maximum
premium limitation, protecting Collective directors and executive officers
against such claims; (3) the conversion of all Original Options held by
directors and executive officers of Collective into New Options, with
adjustments to the exercise     
 
                                       4
<PAGE>
 
   
price and number of shares subject thereto based on the Exchange Ratio, and the
immediate exercisability, pursuant to the terms of the Incentive Plan, of all
New Options granted under the Incentive Plan, whether or not the related
Original Option is exercisable immediately prior to the Effective Time; (4) for
Thomas H. Hamilton, Chairman and Chief Executive Officer of Collective and
Collective Bank, payment of a sum estimated to be approximately $1,561,956
under his employment agreements with Collective and Collective Bank upon a
termination of his employment with Collective or Collective Bank following the
Merger for reasons other than death or "cause" (as defined in the agreements)
and coverage under Collective's employee benefit plans for 36 months; (5) lump
sum payments to each of Edward J. McColgan, Scott T. Page and Bernard H.
Berkman pursuant to their respective change of control agreements with
Collective Bank in the event their employment with Collective Bank (or a
successor) is terminated for reasons other than (i) death or retirement of the
executive, or (ii) by Collective Bank (or a successor) for "cause" (as defined
in the agreements) or due to the disability of the executive, or is terminated
by the executive for "good reason" (as defined in the agreements). Each
agreement currently provides for a term ending December 31, 1998, unless prior
thereto a "change of control" (as defined in the agreements) occurs, in which
case the term is automatically extended to December 31, 1999. The lump sum
payment to each executive would equal the aggregate of the periodic salary and
incentive payments otherwise owed to that executive through the term of his
agreement or for one year, whichever is greater, and any incentive payments or
salary earned prior to the date of termination but not paid, plus life,
disability, accident and health insurance benefits for the greater of one year
or the remaining term of the agreement. Messrs. McColgan, Page and Berkman are
currently paid salary at the annual rates of $186,900, $142,000 and $127,628,
respectively and have target annual incentives of 25%, 20% and 15% of base
salary, respectively; (6) the selection of Mr. Hamilton and one other
Collective Board member to the Summit Board; and (7) for directors of
Collective who participate in the Collective Bancorp Directors Deferred
Compensation Plan, the establishment of a grantor trust in the approximate
amount of $1,522,000 to assist Collective in meeting its liabilities under the
Directors Deferred Compensation Plan. These interests and the underlying
assumptions are described in more detail below under "THE MERGER--Interests of
Certain Persons in the Merger."     
   
DIFFERENCE IN SHAREHOLDERS' RIGHTS     
   
  The rights of Collective stockholders, which are determined by Delaware
corporation law and the Restated Certificate of Incorporation and By-Laws of
Collective, differ from the rights accorded Summit shareholders, which are
determined by New Jersey corporation law and the Restated Certificate of
Incorporation and By-Laws of Summit. Some of the differences in stockholders'
rights are attributable to differences between the corporation law of Delaware,
the state of Collective's incorporation, and the corporation law of New Jersey,
the state of Summit's incorporation. The remaining differences in stockholders
rights are attributable to differences between the Restated Certificate of
Incorporation and By-Laws of Collective and the Restated Certificate of
Incorporation and By-Laws of Summit. Certain of the rights of Collective
stockholders which are provided by Delaware corporation law or contained in the
Restated Certificate of Incorporation or By-Laws of Collective and which are
not provided by New Jersey corporation law or contained in the Restated
Certificate of Incorporation or By-Laws of Summit are deemed to have an anti-
takeover effect and will not be available to Collective stockholders as Summit
shareholders; however, certain rights provided for by New Jersey corporation
law or the Restated Certificate of Incorporation or By-laws of Summit are also
deemed to have an anti-takeover effect and will be available to Collective
stockholders only after becoming Summit shareholders. See "THE MERGER--
Differences in Shareholders' Rights."     
 
STOCK OPTION AGREEMENT
 
  As an inducement and condition to Summit's willingness to enter into the
Merger Agreement, Collective (as issuer) entered into the Collective Stock
Option Agreement (the "Merger Option Agreement") with Summit (as grantee),
dated as of February 28, 1997. The Merger Option Agreement is set forth in
Appendix C to this Proxy Statement-Prospectus.
 
  Pursuant to the Merger Option Agreement, Collective granted to Summit an
irrevocable option (the "Collective Option"), exercisable under certain limited
and specifically defined circumstances, none of which,
 
                                       5
<PAGE>
 
to the best of Summit's and Collective's knowledge, has occurred as of the date
hereof, to purchase up to 4,067,424 shares of Collective Common at a price per
share of $38.125.
   
  The Merger Option Agreement is intended to increase the likelihood that the
Merger will be consummated according to the terms set forth in the Merger
Agreement, and may be expected to discourage offers by third parties to acquire
Collective prior to consummation of the Merger. See "THE MERGER--Stock Option
Agreement."

  NO ASSURANCE CAN BE GIVEN AS TO WHAT THE MARKET PRICE OF SUMMIT COMMON WILL
BE IF AND WHEN THE MERGER IS CONSUMMATED. BECAUSE THE EXCHANGE RATIO IS FIXED

      SUMMARY OF COMPARATIVE AND PRO FORMA PER SHARE FINANCIAL INFORMATION
 
  The following summary presents, for the periods indicated, selected
comparative and pro forma per share financial information: (i) on a historical
basis for both Summit and Collective; (ii) on a pro forma combined basis for
Summit, giving effect to the Merger; and (iii) on a pro forma equivalent basis
per common share for Collective, computed by multiplying the pro forma combined
amount (giving effect to the Merger) by an Exchange Ratio of .895. See "THE
MERGER--Exchange Ratio".
   
  The following unaudited pro forma combined financial information as of and
for the three years ended December 31, 1996 combines the historical audited
financial statements of Summit as of and for the three years ended December 31,
1996, as filed on Form 10-K for the year ended December 31, 1996, and of
Collective as of and for the three fiscal years ended June 30, 1996, as filed
on Form 10-K for the fiscal year ended June 30, 1996, giving effect to the
Merger. The unaudited pro forma combined financial information for the three
months ended March 31, 1997 combines the historical unaudited financial
statements of Summit and Collective at and for the three months ended March 31,
1997 as filed on Form 10-Q. The unaudited pro forma financial information for
the three months ended March 31, 1996, combines the historical unaudited
financial statements of Summit at and for the three months ended March 31, 1996
and the unaudited financial statements of Collective at and for the three
months ended September 30, 1995, to reflect the restatement of the historical
financial statements of Summit that will be recorded on consummation of the
Merger.     
 
  The pro forma information does not reflect anticipated cost savings or
revenue enhancements expected to be realized from the Merger. The unaudited pro
forma financial information does not purport to be indicative of the combined
financial position or results of operations of future periods. See "SELECTED
FINANCIAL DATA" and "PRO FORMA FINANCIAL INFORMATION".

(1) On March 1, 1997, Summit completed the acquisition of B.M.J. Financial
    Corp. This acquisition was accounted for as a pooling of interest, and was
    included in the financial statements as of January 1, 1997. In conjunction
    with this acquisition, a restructuring charge was recorded of $26.5 million
    ($16.7 million or $.17 per common share after tax). In the first quarter of
    1996, restructuring charges totaling $110.7 million ($70.0 million, or $.75
    per common share after tax) were recorded for acquisition-related expenses
    attributable to the acquisitions of The Summit Bancorporation, The
    Flemington National Bank and Trust Company, and Garden State Bancshares,
    Inc. Also included in this restructuring charge were costs related to the
    supermarket branch initiative. During the third quarter of 1996, Summit
    recorded a one-time assessment in conjunction with legislation passed to
    recapitalize the Savings Association Insurance Fund (SAIF) on September 30,
    1996. The assessment amounted to $11.1 million ($6.7 million, or $.07 per
    common share, after tax).     
(2) Summit and pro forma combined net income per common share were computed
    based on net income less preferred dividends divided by the weighted
    average number of shares during the periods presented. Common stock
    equivalents are not included in the calculation as they have no material
    dilutive effect.
(3) The pro forma amounts assume that Summit would have declared cash dividends
    per share equal to its historical dividends per share declared.
   
(4) The pro forma combined book value per share gives effect to the Merger as
    if it had occurred at the end of the period. The March 31, 1997 pro forma
    book value per share also includes the anticipated restructuring charge,
    but does not reflect the estimated expense savings and revenue enhancements
    anticipated from the Merger.

                                 INTRODUCTION
   
  This Proxy Statement-Prospectus is being furnished to Collective
stockholders as of the Record Date in connection with the solicitation of
proxies by the Collective Board for use at the Special Meeting to be held on
July 16, 1997 and any adjournments and postponements thereof, at the Rams Head
Inn, 9 West White Horse Pike (U.S. Highway 30), Absecon, New Jersey, at 10:00
a.m. (local time). The purpose of the Special Meeting is to consider and vote
upon (i) a proposal to approve the Merger Agreement and the transactions
contemplated thereby, and (ii) a proposal to approve the Adjournment Proposal.
    
  The Board of Directors of Collective has approved the Merger Agreement and
unanimously recommends that Collective stockholders vote FOR its approval. The
Board of Directors of Collective also recommends that Collective stockholders
vote FOR approval of the Adjournment Proposal.
 
                                SPECIAL MEETING
 
RECORD DATE; VOTE REQUIRED; REVOCABILITY OF PROXIES
   
  The securities to be voted at the Special Meeting consist of shares of
Collective Common, with each share entitling its owner to one vote on each
proposal and on all other matters properly brought before the Special Meeting.
Collective had no other class of voting securities entitled to vote on the
Merger Agreement or the Adjournment Proposal outstanding at the close of
business on the Record Date. There were 1,415 holders of record of Collective
Common and 20,458,919 shares of Collective Common outstanding and eligible to
be voted at the Special Meeting as of the Record Date. It is anticipated that
this Proxy Statement-Prospectus, together with the enclosed proxy card, will
be mailed to Collective stockholders on or about June 9, 1997.     
   
  The presence at the Special Meeting, in person or by proxy, of the holders
of at least a majority of the shares of Collective Common outstanding on the
Record Date will constitute a quorum for the transaction of business. By
checking the appropriate box on the proxy card provided by the Collective
Board, a stockholder may vote "FOR" a proposal, "AGAINST" a proposal or
"ABSTAIN". Under the Delaware General Corporation Law, the approval of the
proposal to approve the Merger Agreement requires the affirmative vote of a
majority of the shares outstanding and entitled to vote thereon at the Special
Meeting and the approval of the Adjournment Proposal requires the affirmative
vote of a majority of the shares present in person or represented by proxy at
the Special Meeting and entitled to vote thereon. Accordingly, "broker non-
votes" (i.e., shares held by brokers or nominees as to which instructions have
not been received from the beneficial owners or the persons entitled to vote
such shares and with respect to which the broker or nominee does not have
discretionary voting power under the applicable NYSE rules), to the extent
they may be provided by brokers, will have the effect of a vote against the
Merger Agreement but have no effect on whether the Adjournment Proposal is
adopted. Abstentions will be treated as shares that are present and entitled
to vote for purposes of determining the presence of a quorum and the number of
votes necessary to adopt any proposal. If a quorum is not obtained, or if
fewer shares of Collective Common are voted in favor of approval of the Merger
Agreement than the number required for approval, and if the Special Meeting is
postponed or adjourned for the purpose of obtaining additional proxies or
votes, at any subsequent reconvening of the Special Meeting, all proxies will
be voted in the same manner as such proxies would have been voted at the
original convening of the Special Meeting (except for any proxies which have
theretofore effectively been revoked or withdrawn). Proxies voting against
approval of the Merger Agreement will not be used by the proxy holders to vote
in favor of the Adjournment Proposal unless the stockholder has voted FOR
approval of the Adjournment Proposal on the proxy card. The approval of the
Merger Agreement by Collective stockholders is a condition to the consummation
of the Merger. See "THE MERGER--The Merger Agreement--Conditions to the
Merger; Termination."

  If the enclosed form of proxy is properly executed and returned to
Collective in time to be voted at the Special Meeting, the shares represented
thereby will be voted in accordance with the instructions marked thereon.
Proxies that are executed, but as to which no instructions have been marked,
will be voted FOR the approval of the Merger Agreement and FOR the approval of
the Adjournment Proposal, except that if a proxy is voted against the Merger
Agreement and no instruction is given in connection with the Adjournment
Proposal, the proxy will not be voted with respect to the Adjournment
Proposal. Should any other matter properly come before the Special Meeting,
the persons named as proxies in the accompanying proxy, acting by a plurality
of those proxies present, will have discretionary authority to vote on such
matters in accordance with their judgment. As of the time of the preparation
of this Proxy Statement-Prospectus, the Collective Board does not know of any
matters other than those referred to in the Notice of Special Meeting of
Stockholders to be presented for action at the Special Meeting.
   
  Stockholders who execute a proxy retain the right to revoke it at any time
prior to its use. Unless so revoked, the shares represented by such proxies
will be voted at the Special Meeting and all adjournments and postponements
thereof. Prior to the Special Meeting a proxy may be revoked by filing a
written revocation or a duly executed proxy bearing a later date with the
Secretary of Collective, Scott T. Page. During the Special Meeting a proxy may
be revoked by filing a written revocation or a duly executed proxy bearing a
later date with the secretary of the Special Meeting prior to the close of
voting. A proxy will not be voted if a stockholder attends the Special Meeting
and votes in person.     
 
  If a Collective stockholder is participating in Collective's Dividend
Reinvestment Plan (the "Collective Dividend Plan"), such stockholder will
receive a single proxy covering both the shares of Collective Common held by
the Collective stockholder in certificate form and the shares of Collective
Common held on behalf of such stockholder by the Collective Dividend Plan
Administrator in such stockholder's Collective Dividend Plan account. If a
proxy is not returned, shares of Collective Common represented by the proxy,
including any held under the Collective Dividend Plan, will not be voted.
 
  Pursuant to the provisions of the Collective Thrift Plan, Collective Common
held by the Collective Thrift Plan will be voted by the Trustee in the manner
deemed by the Trustee to be in the best interests of the beneficial owners of
such shares.
 
  If a stockholder holds Collective Common through participation in
Collective's Employee Stock Ownership Plan (the "Collective ESOP") the
stockholder will receive a separate card for use in providing instructions to
the ESOP trustee. The ESOP trustee will vote all allocated shares held by the
ESOP in accordance with the instructions received from participants and will
not vote any participants' shares with respect to which instructions are not
received. The trustee of the Collective ESOP will vote all unallocated shares
in the Collective ESOP as instructed by the Administrative Committee of the
Collective ESOP.
 
  If a person holding Collective Common in street name wishes to vote such
Collective Common at the Special Meeting, the person must obtain from the
nominee holding the Collective Common in street name a properly executed
"legal proxy" identifying the individual as a Collective stockholder,
authorizing the Collective stockholder to act on behalf of the nominee at the
Special Meeting and identifying the number of shares with respect to which the
authorization is granted.
 
  The cost of soliciting proxies will be borne by Collective. In addition to
use of the mails, proxies may be solicited personally or by telephone,
telecopier or telegraph by officers, directors or employees of Collective, who
will not be specially compensated for such solicitation activities.
Arrangements will also be made by Collective to reimburse brokerage houses and
other custodians, nominees and fiduciaries for their reasonable expense
incurred in forwarding solicitation materials to the beneficial owners of
shares held of record by such persons. Collective has retained Beacon Hill
Partners, Inc., a proxy soliciting firm, to assist in the solicitation of
proxies, at a fee of $10,000 plus fees for direct telephone solicitations, if
authorized, and reimbursement of certain out-of-pocket costs.

                            SELECTED FINANCIAL DATA
   
  The table below sets forth the selected historical financial information for
Summit at or for each of the years in the five year period ended December 31,
1996 and the three-month periods ended March 31, 1997 and 1996. Such

  The table below sets forth, in summary form, certain unaudited pro forma
combined financial information giving effect to the Merger under the pooling-
of-interests method of accounting. For a description of the pooling-of-
interests accounting method with respect to the Merger, see "THE MERGER--
Accounting Treatment." For purposes of this presentation, the pro forma
results for each of the years in the five year period ended December 31, 1996
include Collective's results at or for its fiscal year ended June 30 of the
same calendar year. The pro forma financial information is prepared based on
the Exchange Ratio in the Merger of .895 shares of Summit Common for each
share of Collective Common. See "THE MERGER--Exchange Ratio". The pro forma
condensed combined financial information does not purport to be indicative of
the combined financial position or results of operations for future periods or
indicative of the results that actually would have been realized had the
entities been a single entity during the periods reflected in the table.

(1) The unaudited pro forma combined financial data for the three months ended
    March 31, 1996 combines the unaudited financial data of Summit at or for
    the three months ended March 31, 1996 with the unaudited financial data of
    Collective at or for the three months ended September 30, 1995 to reflect
    the restatement of the historical financial statements of Summit that will
    be recorded on consummation of the Merger.
(2) Pro forma combined net income per common share was computed based on pro
    forma combined net income less preferred dividends divided by the weighted
    average number of shares outstanding during the period. Common stock
    equivalents are not included in the pro forma calculation as they are not
    material.
(3) Pro forma average common shares outstanding includes the average common
    shares outstanding for Summit plus the average common shares outstanding
    for Collective, adjusted by the Exchange Ratio, less the average common
    shares of Collective adjusted by the Exchange Ratio, owned by Summit.
(4) Balance sheet data as of March 31, 1997 give effect for anticipated
    expenses and charges, net of tax, relating to the Merger but do not
    reflect estimated expense savings and revenue enhancements anticipated to
    result from the Merger.

                        PRO FORMA FINANCIAL INFORMATION
                                  (UNAUDITED)
   
  The following unaudited pro forma condensed combined financial statements
reflect the Merger under the application of the pooling-of-interests method of
accounting. For a description of the pooling-of-interests method of
accounting, see "THE MERGER--Accounting Treatment." This pro forma financial
information is based on the estimates and assumptions set forth in the notes
to such statements. The pro forma adjustments made in connection with the
development of the pro forma information are preliminary and have been made
solely for purposes of developing such pro forma information as necessary to
comply with the disclosure requirements of the Commission. The pro forma
financial information has been prepared using the historical consolidated
financial statements and notes thereto appearing in Summit's Form 10-K for the
year ended December 31, 1996 and Summit's Form 10-Q for the quarterly periods
ended March 31, 1996 and 1997 and Collective's Form 10-K for the fiscal year
ended June 30, 1996 and Collective's Form 10-Q for the quarterly periods ended
September 30, 1995 and March 31, 1997. The unaudited pro forma condensed
combined financial statements do not purport to be indicative of the combined
financial position or results of operations of future periods or indicative of
the results that actually would have been realized had the entities been a
single entity during these periods.     
   
  The Pro Forma Condensed Combined Statements of Income give effect to the
proposed Merger by combining the historical statements of income of Summit for
the three years ended December 31, 1996, as filed on Form 10-K for the year
ended December 31, 1996, and the historical statements of income of Collective
for the three fiscal years ended June 30, 1996, as filed on Form 10-K for the
year ended June 30, 1996. The Pro Forma Condensed Combined Statement of Income
for the three months ended March 31, 1997 combines the unaudited statement of
income of Summit for the three months ended March 31, 1997 and the unaudited
statement of income of Collective for the three months ended March 31, 1997 as
filed on Form 10-Q. The Pro Forma Condensed Combined Statement of Income for
the three months ended March 31, 1996 combines the unaudited statement of
income of Summit for the three months ended March 31, 1996 and the unaudited
statement of income of Collective for the three months ended September 30,
1995, to reflect the restatement of the historical statements of income of
Summit that will be recorded on the consummation of the Merger.     
   
  The Pro Forma Condensed Combined Income Statements do not give effect to
anticipated expenses and nonrecurring charges related to the Merger and the
estimated effect of revenue enhancements and expense savings associated with
the consolidation of the operations of Summit and Collective. Had these
expenses and nonrecurring charges, net of tax effect, been reflected in the
Pro Forma Condensed Combined Income Statements for the three months ended
March 31, 1997, Summit and Collective Pro Forma net income would decrease by
approximately $33.2 million or $.28 per share. The estimated restructuring
charge constitutes forward-looking information and is based on currently
available information as well as numerous factors and assumptions which are
subject to change and could result in a restructuring charge differing from
the estimate.     
   
  The pro forma financial information uses the Exchange Ratio of .895 shares
of Summit Common for each share of Collective Common.

                   NOTES TO PRO FORMA FINANCIAL INFORMATION
 
- --------
   
(1) Reflects the elimination of 163,700 shares of Collective Common owned by
    Summit at March 31, 1997.     
   
(2) The Pro Forma Condensed Combined Balance Sheet gives effect to the Merger
    by combining the respective balance sheets of Summit and Collective at
    March 31, 1997 on a pooling-of-interests basis. The capital accounts have
    been adjusted to reflect the issuance of 18.2 million shares of Summit
    Common in exchange for all the outstanding shares of Collective Common and
    the retirement of Collective Common held in the treasury of Collective.
        
(3) Reflects charges of approximately $49.3 million, $33.2 million after the
    related tax effects, which includes estimated severance and outplacement
    costs, expenses related to facilities closures and consolidation costs
    directly attributable to the Merger.
(4) Average common shares outstanding and net income per common share for
    Collective assume full dilution. Pro forma combined net income per common
    share was computed based on pro forma combined net income less preferred
    dividends divided by the combined weighted average number of shares
    outstanding during the period. Pro forma combined weighted average shares
    includes Collective's weighted average shares outstanding, adjusted for
    the exchange ratio. Common stock equivalents are not included in the pro
    forma calculation as they are not material.

of the execution of the Merger Agreement, the last sale price of a share of
Summit Common was $47.50 and the last sale price of a share of Collective
Common was $42.00. On May 30, 1997, the last sale price of Summit Common was

stockholders are urged to obtain current market quotations.     
 
  NO ASSURANCE CAN BE GIVEN AS TO WHAT THE MARKET PRICE OF SUMMIT COMMON WILL
BE IF AND WHEN THE MERGER IS CONSUMMATED. BECAUSE THE EXCHANGE RATIO IS FIXED
AND BECAUSE THE MARKET PRICE OF SUMMIT COMMON IS SUBJECT TO FLUCTUATION, THE
VALUE OF THE SHARES OF SUMMIT COMMON THAT HOLDERS OF COLLECTIVE COMMON WILL

QUOTATIONS FOR SUMMIT COMMON AND COLLECTIVE COMMON. IN ADDITION, PAST
DIVIDENDS PAID IN RESPECT OF SUMMIT COMMON AND COLLECTIVE COMMON ARE NOT
NECESSARILY INDICATIVE OF FUTURE DIVIDENDS WHICH MAY BE DECLARED AND PAID. NO
ASSURANCE CAN BE GIVEN CONCERNING DIVIDENDS TO BE DECLARED AND PAID IN RESPECT
OF SUMMIT COMMON AND COLLECTIVE COMMON BEFORE OR AFTER THE EFFECTIVE TIME.

COORDINATION AND DETERMINATION OF DIVIDENDS UNDER MERGER AGREEMENT
   
  In order to ensure that Collective stockholders will be paid at least one
but no more than one regular dividend in the calendar quarter in which the
Merger is consummated, Collective has agreed to coordinate with Summit the
declaration of any dividends and the setting of any dividend record or payment
dates. Under the Merger Agreement, Collective may declare a quarterly dividend
up to $.25 per share.     
 
DIVIDEND LIMITATIONS
   
  Summit's primary source of funds to pay dividends to its shareholders is
provided by dividends from its subsidiary banks. At March 31, 1997, the
subsidiary banks of Summit had $194.6 million available, under the most
restrictive limitations, for the payment of dividends to Summit. See "SUMMIT
BANCORP--Description of Business".

                                THE MERGER     
 
  The following information concerning the Merger, insofar as it relates to
matters contained in the Merger Agreement, is qualified in its entirety by
reference to the Merger Agreement, a copy of which is attached hereto as
Appendix A and incorporated herein by reference.
 
GENERAL
 
  The Merger Agreement provides for the merger of Collective with and into
Summit, with Summit being the surviving corporation ("Surviving Corporation").
Upon consummation of the Merger, each outstanding share of Collective Common
other than (i) shares of Collective Common beneficially owned by Summit or a
subsidiary of Summit (other than shares held as a result of debts previously
contracted), if any, (ii) shares of Collective Common held in the treasury of
Collective, if any, and (iii) shares of Collective beneficially owned by
Collective or a subsidiary of Collective (other than shares held as a result
of debts previously contracted), if any, will be converted into and represent
the right to receive the Merger Consideration.
 
CLOSING AND EFFECTIVE TIME
 
  The Merger Agreement provides that, unless otherwise agreed and assuming all
conditions to closing have been satisfied or waived, the closing of the Merger
("Closing") will be held on the date designated by Summit on at least five
business days notice ("Closing Notice") given to Collective. The date for the
Closing designated by Summit may not be later than 45 business days after the
last to occur of the following: (1) if the transactions contemplated by the
Merger Agreement are being contested in any legal proceedings, the date that
all such proceedings have been brought to a conclusion favorable, in the
judgment of Summit and Collective, to the consummation of the transactions
contemplated by the Merger Agreement or such prior date as Summit and
Collective shall elect, whether or not such proceedings have been brought to a
conclusion; or (2) the date on which all Required Approvals are received and
any required waiting periods have expired.
 
  If the Merger Agreement is approved by the requisite vote of Collective
stockholders, all other conditions of the Merger are satisfied or waived and
the Closing is held, the Merger will become effective at the date and time
specified in the New Jersey Certificate or, if filed later than the effective
hour and date set forth in the New Jersey Certificate, the date of filing of
the Delaware Certificate. The New Jersey Certificate and Delaware Certificate
are required by the Merger Agreement to be filed no later than one business
day following the date on which the closing of the Merger occurs ("Closing
Date"). If the Merger Agreement is approved by Collective stockholders on the
scheduled date of the Special Meeting, subject to the satisfaction or waiver
of certain other conditions described herein, it is presently contemplated
that the Effective Time will occur during the third calendar quarter of 1997.
The Merger Agreement may be terminated by either party if, among other things,
the Closing fails to occur on or before January 1, 1998, but a party may not
exercise this right if the failure to close is due solely to that party's
failure to perform or observe agreements required by the Merger Agreement to
be performed or observed by it on or before the Closing Date. See "THE
MERGER--The Merger Agreement--Conditions to the Merger; Termination."
 
CONVERSION OF COLLECTIVE COMMON
   
  Upon consummation of the Merger, the outstanding shares of Collective Common
held by each stockholder of Collective at the Effective Time, other than
shares of Collective Common beneficially owned by Summit or a subsidiary of
Summit (other than shares held as a result of debts previously contracted), if
any, shares of Collective Common held in the treasury of Collective, if any,
and shares of Collective beneficially owned by Collective or a subsidiary of
Collective (other than shares held as a result of debts previously
contracted), if any, will be converted into Summit Common at the Exchange
Ratio of .895 and represent the right of the particular stockholder to receive
the whole shares of Summit Common resulting from the conversion and, in lieu
of any fractional share of Summit Common resulting from the conversion, a Cash
in Lieu Amount equal to the fraction of a whole share represented by the
fractional share multiplied by the closing price of a share of Summit     
 
                                      24
<PAGE>
 
Common on the NYSE-Composite Transactions List on the last trading day prior
to the Effective Time. The
Exchange Ratio is subject to appropriate adjustments in the event that, from
the date of the Merger Agreement to the Effective Time, the outstanding shares
of Summit Common are increased or decreased, changed into or exchanged for a
different number or kind of shares or securities through reorganization,
recapitalization, reclassification, stock dividend, stock split or reverse
stock split or other similar changes.
 
EXCHANGE OF COLLECTIVE CERTIFICATES
 
  Prior to the Effective Time, Summit will appoint First Chicago Trust Company
of New York or another entity reasonably satisfactory to Collective as the
Exchange Agent. As promptly as practicable after the Effective Time, but in no
event more than 7 days after the Exchange Agent receives an accurate and
complete list of all holders of record of outstanding Collective Common as of
the Effective Time, Summit will cause the Exchange Agent to send to each
Collective stockholder a letter of transmittal and instructions for exchanging
their Collective Certificates for a Summit Certificate and, if entitled
thereto, a check representing a Cash In Lieu Amount.
 
  To effect a proper surrender and exchange of Collective Certificates, all
Collective Certificates held by a particular Collective stockholder must be
surrendered to the Exchange Agent by such stockholder with properly executed
and completed letters of transmittal. Until a Collective stockholder has
properly surrendered Collective Certificates, Summit may, at its option,
refuse to pay to such holder dividends or other distributions, if any, payable
to holders of Summit Common after the Effective Time; provided, however, that,
upon proper surrender and exchange of Collective Certificates, there will be
paid to such holders the amount, without interest, of dividends and other
distributions, if any, which became payable prior thereto but which were not
paid. No transfer of Collective Common will be effected on the stock transfer
books of Collective after the Effective Time.
 
  The Exchange Agent shall have reasonable discretion to determine whether
letters of transmittal have been properly completed and executed and to
disregard immaterial defects, and any good faith decisions of Summit regarding
such matters as may be referred to it by the Exchange Agent shall be binding
and conclusive.
 
  Neither certificates for fractions of shares of Summit Common nor scrip
certificates for such fractions will be issued, and holders of Collective
Certificates who would otherwise be entitled to receive fractions of shares of
Summit Common will have none of the rights with respect to such fractions of
shares (including, without limitation, the right to receive dividends) that a
holder of a full share of Summit Common would possess in respect of such full
share, and will receive, in lieu thereof, the Cash In Lieu Amount.
 
  If more than one Collective Certificate is surrendered for the same
Collective stockholder account, the number of whole shares of Summit Common
for which a Summit Certificate will be issued to the owner of such account
pursuant to the Merger Agreement will be computed on the basis of the
aggregate number of shares of Collective Common represented by the Collective
Certificates so surrendered.
 
  COLLECTIVE STOCKHOLDERS SHOULD NOT SURRENDER THEIR COLLECTIVE CERTIFICATES
FOR EXCHANGE UNTIL A LETTER OF TRANSMITTAL, INSTRUCTIONS AND OTHER EXCHANGE
MATERIALS ARE RECEIVED FROM THE EXCHANGE AGENT. HOWEVER, COLLECTIVE
STOCKHOLDERS ARE URGED TO NOTIFY FCTC TRANSFER SERVICES, INC. NOW, AT (908)
205-4511 IF THEIR COLLECTIVE CERTIFICATES ARE LOST, STOLEN, DESTROYED OR NOT
PROPERLY REGISTERED, IN ORDER TO BEGIN THE PROCESS OF ISSUING REPLACEMENT
COLLECTIVE CERTIFICATES.
 
CONVERSION OF COLLECTIVE STOCK OPTIONS
   
  Each Original Option granted pursuant to the Collective Option Plans which
is outstanding and unexercised at the Effective Time will be converted
automatically at the Effective Time into a New Option. All Original Options
granted under the Incentive Plan, whether or not exercisable immediately prior
to the Effective Time, will be converted pursuant to the terms of the
Incentive Plan into a New Option that is immediately exercisable after the
Effective Time. Subject to the adjustment in exercise price and number of
shares, described below, each     
 
                                      25
<PAGE>
 
   
New Option will continue to be governed by the terms of the Collective Option
Plan and Grant Agreement under which the corresponding Original Option was
granted, including terms and provisions governing exercises. In each case, (i)
the number of shares of Summit Common subject to the New Option will be equal
to the number of shares of Summit Common which would have been issued in the
Merger if the shares of Collective Common subject to that option were issued
and outstanding immediately prior to the Effective Time, rounded down to the
next lower full share, and (ii) the exercise price per share of Summit Common
subject to the New Option will be equal to the exercise price per share of
Collective Common subject to the Original Option so converted divided by the
Exchange Ratio.     
   
  Within 30 days after the receipt by Summit of an accurate and complete list
of all holders of Collective options, Summit will issue to each holder of New
Options, upon receipt and cancellation of all agreements under which Original
Options were issued to such holder, appropriate instruments confirming the
conversion described above; provided, however, that Summit will not be
obligated to issue such confirming instruments or any shares of Summit Common
issuable upon exercise of a New Option until the shares of Summit Common
issuable upon exercise of the New Options have been registered with the
Commission and authorized for listing on the NYSE and for sale by any
appropriate state securities regulators, which Summit will use its best
efforts to effect within 30 days after Collective shall have delivered to
Summit the above mentioned option-holder list.     
 
RECOMMENDATION OF COLLECTIVE BOARD
 
  THE MERGER AGREEMENT HAS BEEN APPROVED BY THE COLLECTIVE BOARD. THE
COLLECTIVE BOARD BELIEVES THAT THE MERGER IS IN THE BEST INTERESTS OF
COLLECTIVE STOCKHOLDERS. THE COLLECTIVE BOARD UNANIMOUSLY RECOMMENDS THAT
COLLECTIVE STOCKHOLDERS VOTE FOR THE PROPOSAL TO APPROVE THE MERGER AGREEMENT.
 
BACKGROUND
   
  In Spring, 1996, Collective was approached by a representative of Summit who
expressed Summit's interest in the acquisition of Collective. The substance of
that meeting was reported to the Collective Board but no action was taken on
the overture by Summit at that time. Subsequently, in early November, 1996,
Summit again approached Collective and reiterated its interest in the
acquisition of Collective and requested permission to conduct a preliminary
due diligence review of Collective to determine Summit's level of interest. At
a subsequent meeting, later in November, Collective agreed to provide the
information requested by Summit.     
 
  On December 8, 1996, Collective contacted Merrill Lynch regarding its
representation of Collective in connection with a proposed acquisition
transaction. Collective subsequently entered into a financial advisory
agreement with Merrill Lynch on January 15, 1997. On December 11, 1996,
subsequent to the execution of a confidentiality agreement, certain of the
requested information relating to Collective was provided to Summit.
Negotiations between representatives of Summit and Collective continued and
included discussions relating to such matters as board representation and
treatment of employee benefit plans. The negotiations with Summit were
discussed at the regular meeting of the Collective Board held on December 16,
1996, when the Collective Board reviewed its options of remaining independent,
making further acquisitions, or being acquired. The Collective Board
recognized that the acquisition of Collective by a larger financial
institution could be the best means of maximizing the value of Collective's
shares.
 
  During January, 1997, several meetings between representatives of Summit
management and Collective management were held at which a potential
transaction was discussed and due diligence was conducted. On February 7, 1997
Summit, through its financial advisor, Keefe Bruyette & Woods, Inc., submitted
its preliminary exchange offer to Collective through Merrill Lynch.
Negotiations on the exchange ratio continued up until February 18, 1997 when a
tentative exchange ratio of .895 was agreed upon. Negotiations continued
thereafter on the form of Merger Agreement and various business issues.
 
                                      26
<PAGE>
 
  At a meeting held on February 25, 1997, the Collective Board carefully
reviewed the terms of discussion drafts of a merger agreement and a stock
option agreement prepared by Summit and received presentations from
Collective's management, a representative from Muldoon, Murphy & Faucette,
counsel to Collective, and representatives from Merrill Lynch, Collective's
financial advisor. The Collective Board reviewed a presentation and analyses
prepared by Merrill Lynch and determined that such presentation and analyses
were reasonable. At that meeting, Merrill Lynch delivered to the Collective
Board its oral opinion (subsequently confirmed in writing) to the effect that,
as of that date the Exchange Ratio contemplated by the discussion draft of the
Merger Agreement was fair, from a financial point of view, to the stockholders
of Collective. Following those presentations, the Collective Board unanimously
agreed to an all stock transaction at an exchange ratio of .895 shares of
Summit Common for each share of Collective Common, and approved the agreements
and authorized their execution, subject to further negotiation on various
terms and provisions contained therein. Negotiations between the parties
continued until February 27, 1997, when agreement was reached, the definitive
Merger Agreement and Merger Option Agreement were approved by Collective's
Board in a telephone meeting and the Merger Agreement was executed. The
following day the Merger Option Agreement was executed.
 
REASONS FOR THE MERGER
 
 Collective
 
  In reaching its determination that the Merger is in the best interests of
Collective's stockholders, Collective's Board considered a number of factors.
The following is a summary of the material factors considered by Collective's
Board:
 
  (i) The Collective Board's familiarity with and review of Collective's
      business, operations, financial condition, earnings and prospects;
 
  (ii) The current and prospective economic and competitive environment
       facing Collective and the range of possible values available to
       Collective's stockholders, including the timing and likelihood of
       actually receiving those values;
     
  (iii) The financial presentation of Merrill Lynch, Collective's independent
        financial advisor, and the opinion of Merrill Lynch that, as of the
        date of such opinion, the Exchange Ratio is fair from a financial
        point of view to the stockholders of Collective. A copy of the
        opinion of Merrill Lynch is attached hereto as Appendix B and is
        incorporated herein by reference See "OPINION OF COLLECTIVE'S
        FINANCIAL ADVISOR";     
 
  (iv) The business, operations, financial condition, earnings and prospects
       of Summit;
 
  (v) The fact that consummation of the Merger is not conditioned upon Summit
      obtaining financing for its acquisition of Collective;
 
  (vi) The Board's evaluation of the risks to consummation of the Merger,
       including the risks associated with obtaining all necessary regulatory
       approvals without the imposition of terms or conditions which could be
       materially burdensome to Summit;
 
  (vii) The terms of the Merger Agreement and the Merger Option Agreement
        executed in connection with the Merger; and
 
  (viii) The nature of the consideration to be received in the Merger whereby
         Collective stockholders would receive stock in Summit, thus
         permitting stockholders to defer any tax liability associated with
         the increase in value of their stock associated with the Merger, and
         permitting stockholders to become stockholders of Summit, an
         institution with strong operations, management and earnings.
 
  Following the initial overture by Summit, the Collective Board evaluated the
current and prospective economic and competitive environment facing
Collective, industry trends toward consolidation, known Collective needs and
requirements for investments in staffing, facilities and technology,
anticipated liquidity and capital requirements, prospects for alternative
transactions, and the valuations likely to be placed on Collective
 
                                      27
<PAGE>
 
by potentially interested parties based upon similar transactions. That
information indicated that stockholder value was more likely to be maximized
through an acquisition of Collective than through continued independent
operations. Subsequently, Collective's Board reviewed and evaluated the
financial presentation of Merrill Lynch, which served to confirm the
independently obtained data, and reviewed data and other published material
relating to Summit's ability to consummate and fund the proposed transaction
and obtain regulatory approval without being subjected to burdensome
conditions.
 
  Because of the wide variety of factors considered in connection with its
evaluation of the Merger, Collective's Board did not find it practical to, and
did not, quantify or otherwise attempt to assign relative weights to the
specific factors considered in reaching its determination.
 
  THE COLLECTIVE BOARD UNANIMOUSLY RECOMMENDS THAT COLLECTIVE STOCKHOLDERS
VOTE "FOR" APPROVAL OF THE MERGER AGREEMENT.
 
  Summit. The Summit Board believes the Merger is consistent with Summit's
long-term acquisition strategy and will enhance and expand Summit's retail
franchise and competitive position in key market areas.
 
OPINION OF COLLECTIVE'S FINANCIAL ADVISOR
 
  On January 15, 1997 Collective engaged Merrill Lynch to act as its exclusive
financial advisor in connection with the Merger. Pursuant to the terms of its
engagement, Merrill Lynch agreed to assist Collective in analyzing,
structuring, negotiating and effecting a transaction with Summit. Collective
selected Merrill Lynch because Merrill Lynch is a nationally recognized
investment banking firm with substantial experience in transactions similar to
the Merger and is familiar with Collective and its business. As part of its
investment banking business, Merrill Lynch is continually engaged in the
valuation of businesses and their securities in connection with mergers and
acquisitions.
   
  As part of its engagement, representatives of Merrill Lynch attended the
meeting of the Collective Board held on February 25, 1997 (in person) and
February 27, 1997 (via conference call) at which the Collective Board
considered and approved the Merger Agreement. At the February 25, 1997
meeting, Merrill Lynch rendered an oral opinion (subsequently confirmed in
writing) that, as of such date, the Exchange Ratio was fair to the holders of
shares of Collective Common from a financial point of view. Such opinion was
reconfirmed in writing as of the date of this Proxy Statement-Prospectus.     
 
  The full text of Merrill Lynch's updated written opinion dated as of the
date of this Proxy Statement-Prospectus is attached as Appendix B to this
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 Appendix B. Collective stockholders are urged to read the opinion
in its entirety for a description of the procedures followed, assumptions
made, matters considered, and qualifications and limitations on the review
undertaken by Merrill Lynch in connection therewith.
   
  MERRILL LYNCH'S OPINION IS DIRECTED TO THE COLLECTIVE BOARD AND ADDRESSES
ONLY THE EXCHANGE RATIO. IT DOES NOT ADDRESS THE UNDERLYING BUSINESS DECISION
TO PROCEED WITH THE MERGER AND DOES NOT CONSTITUTE A RECOMMENDATION TO ANY
COLLECTIVE STOCKHOLDER AS TO HOW SUCH STOCKHOLDER SHOULD VOTE AT THE SPECIAL
MEETING WITH RESPECT TO THE MERGER OR ANY OTHER MATTER RELATED THERETO.     
   
  Merrill Lynch has informed Collective that in arriving at its written
opinion, Merrill Lynch, among other things: (1) reviewed Collective's Annual
Reports on Form 10-K and related audited financial information for the three
fiscal years ended June 30, 1996 and Collective's quarterly reports on Form
10-Q and related unaudited financial information for the quarterly periods
ended March 31, 1997, December 31, 1996 and September 30, 1996; (2) reviewed
Summit's Annual Reports on Form 10-K and related audited financial information
for the three fiscal years ended December 31, 1996 and Summit's quarterly
report on Form 10-Q and related unaudited financial information for the
quarterly period ended March 31, 1997; (3) reviewed certain limited financial
information, including financial forecasts, relating to the respective
businesses, earnings, assets and prospects of     
 
                                      28
<PAGE>
 
   
Collective and Summit furnished to Merrill Lynch by senior management of
Collective and Summit as well as projected cost savings and related expenses
expected to result from the Merger (the "Expected Savings") furnished to it by
senior management of Summit; (4) conducted certain limited discussions with
members of senior management of Collective and Summit concerning the
respective businesses, financial condition, earnings, assets, liabilities,
operations, regulatory condition, financial forecasts, contingencies and
prospects of Collective and Summit and their respective views as to the future
financial performance of Collective, Summit, and the combined entity, as the
case may be, following the Merger; (5) reviewed the historical market prices
and trading activity for Collective Common and Summit Common and compared them
with that of certain publicly traded companies which Merrill Lynch deemed to
be relevant; (6) compared the respective results of operations of Collective
and Summit with those of certain companies which Merrill Lynch deemed to be
relevant; (7) compared the proposed financial terms of the Merger contemplated
by the Merger Agreement with the financial terms of certain other mergers and
acquisitions which Merrill Lynch deemed to be relevant; (8) reviewed the
amount and timing of the Expected Savings following the Merger as prepared,
and discussed with it, by senior management of Summit; (9) considered, based
upon information provided by Summit's senior management, the pro forma impact
of the Merger on the earnings and book value per share, consolidated
capitalization and certain balance sheet and profitability ratios of Summit;
(10) reviewed the Merger Agreement and the Merger Option Agreement; and (11)
reviewed such other financial studies and analyses and performed such other
investigations and took into account such other matters as Merrill Lynch
deemed necessary.     
   
  In preparing its opinion, Merrill Lynch, with Collective's consent, assumed
and relied on the accuracy and completeness of all financial and other
information supplied or otherwise made available to it by Collective and
Summit, including that contemplated in the numbered items above, and Merrill
Lynch has not assumed responsibility for independently verifying such
information or undertaken an independent evaluation or appraisal of the assets
or liabilities, contingent or otherwise, of Collective or Summit or any of
their subsidiaries, nor has it been furnished any such evaluation or
appraisal. Merrill Lynch is not an expert in the evaluation of allowances for
loan losses, and, with Collective's consent, it has not made an independent
evaluation of the adequacy of the allowances for loan losses of Collective or
Summit, nor has it reviewed any individual credit files relating to Collective
or Summit, and, with Collective's consent, it assumed that the respective
aggregate allowances for loan losses for both Collective and Summit are
adequate to cover such losses and will be adequate on a pro forma basis for
the combined entity. In addition, it has not conducted any physical inspection
of the properties or facilities of Collective or Summit. With Collective's
consent, Merrill Lynch also assumed and relied upon the senior management of
Collective and Summit as to the reasonableness and achievability of the
financial forecasts (and the assumptions and bases therefore) provided to, and
discussed with, Merrill Lynch. In that regard, Merrill Lynch has assumed with
Collective's consent that such forecasts, including without limitation,
financial forecasts, evaluations of contingencies, Expected Savings and
operating synergies resulting from the Merger and projections regarding
underperforming and non-performing assets, net charge-offs, adequacy of
reserves, future economic conditions and results of operations reflect the
best currently available estimates and judgments of the senior management of
Collective and Summit as to the expected future financial performance of
Collective, Summit and/or the combined entity, as the case may be. Merrill
Lynch's opinion is predicated on the Merger receiving the tax and accounting
treatment contemplated in the Merger Agreement. Merrill Lynch's opinion was
necessarily based on economic, market and other conditions as in effect on,
and the information made available to it as of, the date of its opinion.     
 
  Merrill Lynch's opinion was rendered without regard to the necessity for, or
level of, any restrictions, obligations, undertakings or divestitures which
may be imposed or required in the course of obtaining regulatory approval for
the Merger.
 
  In connection with rendering its opinion dated February 25, 1997, Merrill
Lynch performed a variety of financial analyses, consisting of those
summarized below. The summary set forth below does not purport to be a
complete description of the analyses performed by Merrill Lynch in this
regard, although it describes all material analyses performed by Merrill
Lynch. The preparation of a fairness opinion involves various determinations
as to the most appropriate and relevant methods of financial analysis and the
application of these methods to the
 
                                      29
<PAGE>
 
particular circumstances and, therefore, such an opinion is not readily
susceptible to a partial analysis or summary description. Accordingly,
notwithstanding the separate factors summarized below, Merrill Lynch believes
that its analyses must be considered as a whole and that selecting portions of
its analyses and factors considered by it, without considering all analyses
and factors, or attempting to ascribe relative weights to some or all such
analyses and factors, could create an incomplete view of the evaluation
process underlying Merrill Lynch's opinion.
 
  In performing its analyses, Merrill Lynch made numerous assumptions with
respect to industry performance, general business and economic conditions and
other matters, many of which are beyond the control of Summit, Collective and
Merrill Lynch. The analyses performed by Merrill Lynch are not necessarily
indicative of actual values or future results, which may be significantly more
or less favorable than suggested by such analyses. Such analyses were prepared
solely as part of Merrill Lynch's analysis of the fairness to the stockholders
of Collective of the Exchange Ratio and were provided to the Collective Board
in connection with the delivery of Merrill Lynch's opinion. Merrill Lynch gave
the various analyses described below approximately similar weight and did not
draw any specific conclusions from or with regard to any one method of
analysis. With respect to the comparison of selected companies analysis and
the analysis of selected thrift merger transactions summarized below, no
company utilized as a comparison is identical to Collective or Summit.
Accordingly, an analysis of comparable companies and comparable business
combinations is not mathematical; rather it involves complex considerations
and judgments concerning the differences in financial and operating
characteristics of the companies and other factors that could affect the
public trading values or announced merger transaction values, as the case may
be, of the companies concerned. The analyses do not purport to be appraisals
or to reflect the prices at which Collective or Summit might actually be sold
or the prices at which any securities may trade at the present time or at any
time in the future. In addition, as described above, Merrill Lynch's opinion
is just one of many factors taken into consideration by the Collective Board.
 
  The projections furnished to Merrill Lynch and used by it in certain of its
analyses were prepared by the senior management of Summit and Collective.
Collective and Summit do not publicly disclose internal management projections
of the type provided to Merrill Lynch in connection with its review of the
Merger, and as a result, such projections were not prepared with a view
towards public disclosure. The projections were based on numerous variables
and assumptions which are inherently uncertain, including, without limitation,
factors related to general economic and competitive conditions, and
accordingly, actual results could vary significantly from those set forth in
such projections.
 
  The following is a summary of the material analyses presented by Merrill
Lynch to the Collective Board on February 25, 1997 (the "Merrill Lynch
Report") in connection with its February 25, 1997 opinion.
 
  Summary of Proposal. Merrill Lynch reviewed the terms of the proposed
transaction, including the Exchange Ratio and the implied aggregate
transaction value. Based on Summit's closing stock price of $49.13 on February
21, 1997, Merrill Lynch calculated an implied transaction value per share of
Collective of $43.97, and an implied total transaction value of approximately
$909 million. Based on such implied total transaction value, Merrill Lynch
also calculated the price to market, price to book, price to tangible book and
price to earnings multiples, and the implied deposit premium paid (defined as
the transaction value minus the tangible book value divided by total deposits)
for Collective in the Merger. This analysis yielded a price to market multiple
of 1.20x , a price to book value multiple of 2.42x, a price to tangible book
value multiple of 2.69x, a price to last twelve months earnings multiple
(excluding the Savings Association Insurance Fund Assessment) of 15.67x, and
an implied deposit premium of 16.07%.
   
  Pro Forma Merger Analysis. Based on publicly available earnings forecasts
from third parties and projections provided by Summit and Collective,
including pre-tax fully-phased-in Expected Savings assumption of $18 million
in 1998 and pre-tax merger and reorganization charges of $45 million, Merrill
Lynch analyzed certain pro forma effects of the Merger. This analysis
indicated that the transaction would be accretive to projected earnings per
share of Summit Common in 1997 and thereafter and that the Merger would be
dilutive to Summit's book value and tangible book value per share at the
assumed closing of the Merger (September 30,     
 
                                      30
<PAGE>
 
   
1997). In this analysis, Merrill Lynch assumed that Summit and Collective
performed in accordance with the publicly available earnings forecasts from
third parties and Expected Savings assumptions provided to Merrill Lynch by
Summit's and Collective's senior management.     
   
  Discounted Dividend Stream Analysis--Collective. Using a discounted dividend
stream analysis, Merrill Lynch estimated the present value of the future
streams of after-tax cash flows that Collective could produce and distribute
to stockholders ("dividendable net income") on a stand-alone basis from 1997
through 2002. Merrill Lynch assumed that Collective performed in accordance
with publicly available earnings forecasts from third parties in 1997 and
1998, increased at 10.00% per annum thereafter, and that Collective's tangible
common equity to tangible asset ratio would be maintained at a minimum 6.0%
level. Merrill Lynch estimated the terminal values for the Collective common
stock at 9.0, 10.0 and 11.0 times Collective's 2003 estimated operating income
(defined as net income before intangible amortization). The dividendable net
income streams and terminal values were then discounted to present values
using different discount rates (ranging from 13% to 15%) chosen to reflect
different assumptions regarding required rates of return of holders or
prospective buyers of Collective Common. This discounted dividend stream
analysis indicated a reference range of $32.23 to $40.60 per share for
Collective Common. As indicated above, this analysis is not necessarily
indicative of actual values or actual future results and does not purport to
reflect the prices at which any securities may trade at the present or at any
time in the future. Merrill Lynch noted that the discounted dividend stream
analysis is a widely used valuation methodology, but the results of such
methodology are highly dependent upon the numerous assumptions that must be
made, including earnings growth rates, dividend payout rates, terminal values
and discount rates.     
 
  Analysis of Selected Thrift Merger Transactions--Collective. Merrill Lynch
reviewed publicly available information regarding eleven thrift merger
transactions with a value greater than $500 million and less than $2 billion
which had occurred in the United States since January 1, 1993 that it deemed
to be relevant (the "Comparable Transactions"). The Comparable Transactions
and the month in which they were announced are: Mercantile Bancorp.'s proposed
acquisition of Roosevelt Financial (December, 1996); ABN-AMRO Holding's
proposed acquisition of Standard Federal Bancorp (November, 1996); HSBC
Holding's acquisition of First FS&LA of Rochester (August, 1996); MacAndrews &
Forbes Holdings Inc.'s acquisition of Cal Fed Bancorp (July, 1996); Washington
Mutual, Inc.'s acquisition of American Savings Bank (July, 1996); Republic New
York Corporation's acquisition of Brooklyn Bancorp Inc. (September, 1995);
NationsBank Corporation's acquisition of CSF Holdings, Inc. (July, 1995);
First Union Corporation's acquisition of Coral Gables Fedcorp (January, 1995);
First Bank System, Inc.'s acquisition of Metropolitan Financial Corporation
(July, 1994); MacAndrews & Forbes Holdings Inc.'s acquisition of First
Nationwide Bank (April, 1994); and ABN-AMRO Holding's acquisition of Cragin
Financial Inc. (July, 1993). Merrill Lynch compared the price to book value,
price to tangible book value and price to earnings ratios and the implied
deposit premium paid in the Merger to the corresponding ratios for the
Comparable Transactions. This analysis yielded a range of (i) price to book
value multiples of 0.85x to 2.11x with a mean of 1.61x and a median of 1.63x
(compared with a multiple of 2.42x for Collective using the February 21, 1997
price for Summit Common), (ii) price to tangible book value multiples of 1.11x
to 2.60x with a mean of 1.74x and a median of 1.67x (compared with a multiple
of 2.69x for Collective using the February 21, 1997 price for Summit Common),
(iii) price to trailing twelve months earnings multiples of 11.19x to 14.37x
with a mean of 12.81x and a median of 12.76x (compared with a multiple of
15.67x for Collective using the February 21, 1997 price for Summit Common),
and (iv) implied deposit premiums paid of 1.08% to 11.92% with a mean of 7.03%
and a median of 6.56% (compared with a premium of 16.07% for Collective using
the February 21, 1997 price for Summit Common). This analysis yielded an
overall imputed reference range per share of Collective Common of $27.30 to
$36.24 based on the mean and median imputed range.
 
  No company or transaction used in the above analysis as a comparison is
identical to Collective or the Merger respectively. Accordingly, an analysis
of the results of the foregoing necessarily involves complex considerations
and judgments concerning differences in financial and operating
characteristics of the companies and other factors that could affect the
public trading values or announced merger transaction values, as the case may
be, of Collective and the companies to which it is being compared.

  Comparison of Selected Comparable Companies--Collective. In connection with
the Merrill Lynch Report, Merrill Lynch compared selected operating and stock
market results of Collective to the publicly available corresponding data of
certain other companies which Merrill Lynch deemed to be relevant, including
ALBANK Financial Corporation, Sovereign Bancorp, Inc., Astoria Financial
Corp., Webster Financial Corp., Commercial Federal Corporation, Eagle
Financial Corporation, Security Capital Corporation, and St. Paul Bancorp,
Inc. (collectively the "Collective Composite") This comparison showed, among
other things, that for the December 31, 1996 quarter annualized (i)
Collective's ratio of noninterest expense to average assets was 1.38%,
compared to a mean of 1.89% for the Collective Composite, (ii) Collective's
ratio of noninterest income to average assets was 0.30%, compared to a mean of
0.49% for the Collective Composite, (iii) Collective's net interest margin was
2.95%, compared with a mean of 3.09% for the Collective Composite, (iv)
Collective's efficiency ratio (defined as noninterest expenses divided by the
sum of noninterest income and net interest income before provision for loan
losses) was 39.44%, compared with a mean of 51.83% for the Collective
Composite, (v) Collective's return on average assets was 1.12%, compared to a
mean of 0.95% for the Collective Composite and (vi) Collective's return on
average equity was 16.32%, compared to a mean of 12.43% for the Collective
Composite. This comparison also indicated that (i) at December 31, 1996, (A)
Collective's tangible equity to tangible asset ratio was 6.14%, compared to a
mean of 7.22% for the Collective Composite, (B) Collective's ratio of
nonperforming loans to total loans was 0.72%, compared with a mean of 0.79%
for the Collective Composite, (C) Collective's ratio of nonperforming assets
to total assets was 0.38%, compared with a mean of 0.63% for the Collective
Composite, (D) Collective's ratio of loan loss reserves to nonperforming
assets was 65.46%, compared with a mean of 139.65% for the Collective
Composite, (ii) as of February 21, 1997, (A) the ratio of Collective's market
price to estimated earnings for the twelve-month period ending fiscal year
1997 was 10.31x, compared to a mean of 11.45x for the Collective Composite
(assuming reported average earnings estimates based on data from First Call
for both Collective and the Collective Composite), (B) the ratio of
Collective's market price to book value per share at December 31, 1996 was
2.01x, compared to a mean of 1.59x for the Collective Composite, (C) the ratio
of Collective's market price to tangible book value per share at December 31,
1996 was 2.23x, compared to a mean of 1.90x for the Collective Composite, and
(iii) as of December 31, 1996, Collective's dividend yield was 2.70%, compared
to a mean of 1.58% for the Collective Composite.
   
  Discounted Dividend Stream Analysis--Summit. Using a discounted dividend
stream analysis, Merrill Lynch estimated the present value of dividendable net
income that Summit could produce on a stand-alone basis from 1997 through
2002. Merrill Lynch assumed that Summit performed in accordance with publicly
available earnings forecasts from third parties in 1997 and 1998, grows at
10.00% per annum thereafter, and that Summit's tangible common equity to
tangible asset ratio would be maintained at a minimum 6.0% level. Merrill
Lynch estimated the terminal values for the Summit Common at 11.0, 12.0 and
13.0 times Summit's 2003 estimated operating income (defined as net income
before intangible amortization). The dividendable net income streams and
terminal values were then discounted to present values using different
discount rates (ranging from 12% to 14%) chosen to reflect different
assumptions regarding required rates of return of holders or prospective
buyers of Summit Common. This discounted dividend stream analysis indicated a
reference range of $46.20 to $55.93 per share for Summit Common. As indicated
above, this analysis is not necessarily indicative of actual values or actual
future results and does not purport to reflect the prices at which any
securities may trade at the present or at any time in the future. Merrill
Lynch noted that the discounted dividend stream analysis is a widely used
valuation methodology, but the results of such methodology are highly
dependent upon the numerous assumptions that must be made, including earnings
growth rates, dividend payout rates, terminal values and discount rates.     
   
  Comparison of Selected Comparable Companies--Summit. Merrill Lynch compared
selected operating and stock market results of Summit to the publicly
available corresponding data of certain other companies which Merrill Lynch
deemed to be relevant, including AmSouth Bancorp, Crestar Financial
Corporation, First of America Bank Corp., Firstar Corp., Huntington
Bancshares, Inc., Mercantile Bancorporation Inc., Regions Financial
Corporation, and Southern National Corporation (collectively the "Summit
Composite"). This comparison showed, among other things, that, according to
publicly available data from third parties, for the December 31, 1996 quarter
annualized (i) Summit's ratio of noninterest expense to average assets was
2.81%,     
 
                                      32
<PAGE>
 
   
compared to a mean of 3.11% for the Summit Composite, (ii) Summit's ratio of
noninterest income to average assets was 1.13%, compared to a mean of 1.57%
for the Summit Composite, (iii) Summit's net interest margin was 4.52%,
compared to a mean of 4.37% for the Summit Composite, (iv) Summit's efficiency
ratio (defined as noninterest expenses divided by the sum of noninterest
income and net interest income before provision for loan losses) was 53.34%,
compared with a mean of 55.27% for the Summit Composite, (v) Summit's return
on average assets was 1.48%, compared to a mean of 1.37% for the Summit
Composite and (vi) Summit's return on average equity was 17.36%, compared to a
mean of 16.65% for the Summit Composite. This comparison also indicated that
(i) at December 31, 1996, (A) Summit's tangible equity to tangible asset ratio
was 8.06%, compared to a mean of 7.22% for the Summit Composite, (B) Summit's
ratio of nonperforming loans to total loans was 1.09%, compared with a mean of
0.61% for the Summit Composite, (C) Summit's ratio of nonperforming assets to
total assets was 0.78%, compared with a mean of 0.44% for the Summit
Composite, (D) Summit's ratio of loan loss reserves to nonperforming assets
was 146.40%, compared with a mean of 236.43% for the Summit Composite, (ii) as
of February 21, 1997, (A) the ratio of Summit's market price to estimated
earnings for the twelve-month period ending fiscal year 1997 was 12.22x,
compared to a mean of 12.28x for the Summit Composite (assuming reported
average earnings estimates based on publicly available data from third parties
for both Summit and the Summit Composite), (B) the ratio of Summit's market
price to book value per share at December 31, 1996 was 2.40x, compared to a
mean of 2.20x for the Summit Composite, (C) the ratio of Summit's market price
to tangible book value per share at December 31, 1996 was 2.54x, compared to a
mean of 2.48x for the Summit Composite, and (iii) as of December 31, 1996,
Summit's dividend yield was 2.93%, compared to a mean of 2.80% for the Summit
Composite. Certain of this data may differ with Summit's audited financial
data as found in Summit's 1996 Form 10-K Financial Statements.     
 
  In connection with its opinion dated as of the date of this Proxy Statement-
Prospectus, Merrill Lynch performed procedures to update, as necessary,
certain of the analyses described above and reviewed the assumptions on which
such analyses described above were based and the factors considered in
connection therewith. Merrill Lynch did not perform any analyses in addition
to those described above in updating its February 25, 1997 opinion.
 
  Merrill Lynch has been retained by the Board of Directors of Collective as
an independent contractor to act as financial adviser to Collective with
respect to the Merger. Merrill Lynch is a nationally recognized investment
banking firm which, among other things, regularly engages in the valuation of
businesses and securities, including banking institutions, in connection with
mergers and acquisitions. In addition, within the past two years, Merrill
Lynch has provided financial advisory, investment banking and other services
to Collective and Summit and has received fees of approximately $275,000 and
$4.0 million, respectively, for the rendering of such investment banking
services. In the ordinary course of its business, Merrill Lynch and its
affiliates may actively trade the securities of Collective and Summit for
their own account and for the accounts of customers and, accordingly, may from
time to time hold a long or short position in such securities.
   
  Collective and Merrill Lynch have entered into a letter agreement dated
January 15, 1997 relating to the services to be provided by Merrill Lynch in
connection with the Merger. Collective has agreed to pay Merrill Lynch fees as
follows: (i) a cash fee of $50,000, which was paid upon the execution of the
letter agreement; (ii) a cash fee of $200,000, which was paid upon execution
of the Merger Agreement; (iii) a cash fee of $200,000 which was payable at the
mailing of the Proxy Statement-Prospectus; and (iv) an additional fee of
$5,869,000 payable in cash at the Closing of the Merger. In such letter,
Collective also agreed to reimburse Merrill Lynch for its reasonable out-of-
pocket expenses incurred in connection with its advisory work, including the
reasonable fees and disbursements of its legal counsel, and to indemnify
Merrill Lynch against certain liabilities relating to or arising out of the
Merger, including liabilities under the federal securities laws.     
 
MERGER OPTION AGREEMENT
 
  As an inducement and condition to Summit's willingness to enter into the
Merger Agreement, Collective (as issuer) entered into the Merger Option
Agreement with Summit (as grantee). Pursuant to the Merger Option Agreement,
Collective granted the Collective Option to Summit. The Collective Option is
an option to purchase up to 4,067,024 shares of Collective Common at a price
per share of $38.125, exercisable as described below.
 
                                      33
<PAGE>
 
The purchase of any shares of Collective Common pursuant to the Collective
Option is subject to compliance with applicable law.
 
  Unless Summit is in breach of any material covenant or obligation contained
in the Merger Agreement and, if the Merger Agreement has not terminated prior
thereto, such breach would entitle Collective to terminate the Merger
Agreement, Summit may exercise the Collective 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 that the Collective Option will terminate upon
the earliest to occur of certain events, including:
 
    (1) the time immediately prior to the Effective Time;
 
    (2) termination of the Merger Agreement prior to the occurrence of an
  Extension Event (as defined below) (other than a termination by Summit
  resulting from a breach thereof by Collective which has not been cured or
  is not capable of being cured within the time allotted); or
 
    (3) 15 months after the termination of the Merger Agreement following the
  occurrence of an Extension Event (as defined below) or the termination of
  the Merger Agreement by Summit upon a breach by Collective which has not
  been cured or is not capable of being cured within the time allotted.
 
  The term "Extension Event" shall mean the occurrence of certain events
without Summit's prior written consent, including:
 
    (1) Collective, its Board of Directors or any of its subsidiaries taking
  certain actions (each an "Acquisition Transaction"), including recommending
  or entering into an agreement with any third party to effect (a) a merger,
  consolidation or similar transaction involving Collective or any of its
  banking subsidiaries, (b) the purchase, lease, or other acquisition of 10
  percent or more of the aggregate value of the assets or deposits of
  Collective or any of its banking subsidiaries, (c) the purchase or other
  acquisition of securities representing 10 percent or more of the voting
  power of Collective or any of its banking subsidiaries or (d) any
  substantially similar transaction, in each case except as otherwise
  permitted by the Merger Option Agreement;
 
    (2) any third party acquiring beneficial ownership or the right to
  acquire beneficial ownership of 10 percent or more of the aggregate voting
  power of Collective or any of its banking subsidiaries;
 
    (3) any third party making a bona fide proposal to Collective or its
  stockholders, by public announcement or written communication that is or
  becomes publicly disclosed, to engage in an Acquisition Transaction
  (including the commencement of a tender offer or exchange offer to purchase
  10 percent or more of the aggregate voting power of Collective or any of
  its banking subsidiaries);
 
    (4) after a proposal by a third party to Collective or its stockholders
  to engage in an Acquisition Transaction, Collective breaches (without cure)
  any representation or covenant in the Merger Agreement which would entitle
  Summit to terminate the Merger Agreement;
 
    (5) any third party filing an application with any federal or state bank
  regulatory authority for approval to engage in an Acquisition Transaction;
 
    (6) failure of the stockholders of Collective to approve the Merger
  Agreement, failure of the Collective Board of Directors to call a meeting
  for consideration of the Merger or cancellation of such a meeting, or
  Collective's Board of Directors shall have withdrawn or modified in a
  manner adverse to the consummation of the Merger the recommendation of
  Collective's Board with respect to the Merger Agreement, in each case after
  an Extension Event; or
 
    (7) any Purchase Event (as defined below).
 
 
                                      34
<PAGE>
 
The term "Purchase Event" shall mean either of the following events or
transactions:
 
    (1) any person other than Summit or a subsidiary of Summit acquiring
  beneficial ownership of 25 percent or more of the aggregate voting power of
  Collective or any of its banking subsidiaries, except as otherwise
  permitted by the Merger Option Agreement; or
 
    (2) the occurrence of an Extension Event described in subparagraph (1) of
  the definition of "Extension Event" above, except that the percentage
  referred to in clauses (b) and (c) thereof shall be 25 percent.
 
  Upon the occurrence of certain events set forth in the Merger Option
Agreement, at the election of Summit, the Collective Option (or shares issued
pursuant to the exercise thereof) must be repurchased by Collective (the
"Repurchase"), or converted into, or exchanged for, an option of another
corporation or Collective (the "Substitute Option"). In addition, the Merger
Option Agreement grants certain registration rights ("Registration Rights") to
Summit with respect to the shares represented by the Collective Option. The
terms of such Repurchase, Substitute Option and Registration Rights are set
forth in the Merger Option Agreement.
 
  The Merger Option Agreement and the Collective Option are intended to
increase the likelihood that the Merger will be consummated according to the
terms set forth in the Merger Agreement and may be expected to discourage
offers by third parties to acquire Collective prior to the Merger.
 
  To the knowledge of Summit and Collective, no event giving rise to the right
to exercise the Collective Option has occurred as of the date of this Proxy
Statement-Prospectus.
 
  A copy of the Merger Option Agreement is set forth in Appendix C to this
Proxy Statement-Prospectus, and reference is made thereto for the complete
terms of the Merger Option Agreement and the Collective Option. The foregoing
discussion is qualified in its entirety by reference to the Merger Option
Agreement.
 
REGULATORY APPROVALS
 
  The Merger is subject to approval by the Federal Reserve Board under Section
4 of the Bank Holding Company Act of 1956, as amended (the "BHC Act"). Section
4 of the BHC Act provides that a bank holding company shall not acquire the
voting shares of any company that is not a bank (including the shares of a
savings bank such as Collective Bank) unless the Federal Reserve Board
determines that the transaction can reasonably be expected to produce benefits
to the public that outweigh possible adverse effects such as undue
concentration of resources, decreased or unfair competition, conflicts of
interest, or unsound banking practices.
 
  Under the BHC Act, as interpreted by the Federal Reserve Board and the
courts, the Federal Reserve Board may deny any application if it determines
that the financial or managerial resources of the acquiring bank holding
company are inadequate. The acquisition by Summit of more than 5% of
Collective's voting stock is subject to the same approval requirements as
described above. Satisfactory financial condition, particularly with regard to
capital adequacy, and satisfactory Community Reinvestment Act ratings are
generally prerequisites to obtaining Federal Reserve Board approval to make
acquisitions. All of Summit's subsidiary banks are currently rated
"satisfactory" or better under the Community Reinvestment Act.
 
  An application with respect to the Merger was filed by Summit with the
Federal Reserve Board on April 21, 1997. Regulations of the Federal Reserve
Board under the BHC Act require notice of an application for approval of the
Merger to be published in newspapers of general circulation and in the Federal
Register and that the public have at least 30 days to comment on the
application. In the event one or more comments protesting approval of the
application are received by the Federal Reserve Board within the time period
provided for in the respective notices, the Federal Reserve Board's
regulations permit the Federal Reserve Bank having jurisdiction over the
applicant, acting on delegated authority from the Federal Reserve Board, to
arrange a private meeting between the applicant and the protesters if the
Federal Reserve Bank decides such a meeting would be appropriate. In addition,
if an applicant or a protestor requests a hearing or if the Federal Reserve
Board determines such to be appropriate, the Federal Reserve Board may order
that a formal hearing on the application
 
                                      35
<PAGE>
 
   
be held or that a proceeding permitting all interested parties to present
their views orally before the Federal Reserve Board or its designated
representative be conducted. Due to the possibility that a private meeting,
public hearing or proceeding providing for oral presentation will be scheduled
by the Federal Reserve Board following receipt of a protest, and due
additionally to the procedures relating thereto, Federal Reserve Board
processing of merger applications receiving one or more protests will
generally take longer than the processing of merger applications not receiving
such protests. The comment period relating to Summit's application for
approval of the Merger expired on or about May 23, 1997 and the application
was approved by the Federal Reserve Board on May 29, 1997.     
   
  All materials filed with the Federal Reserve Board were also filed with the
U.S. Department of Justice and the Federal Trade Commission pursuant to the
Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended. Such
materials must be on file for 30 days before the Merger is consummated.     
   
  Collective stockholders should be aware that regulatory approvals of the
Merger may be based upon different considerations than those that would be
important to such stockholders in determining whether or not to approve the
Merger Agreement. Any such approvals should in no event be construed by a
Collective stockholder as a recommendation by any regulatory agency with
respect to the Merger.     
 
INTERESTS OF CERTAIN PERSONS IN THE MERGER
 
  Directors and executive officers of Collective have interests in the Merger
that are in addition to their interests as Collective stockholders. These
interests are described in more detail below.
 
Indemnification
 
  In the Merger Agreement, Summit has agreed to indemnify and to advance
expenses in matters that may be subject to indemnification to persons who
served as directors and officers of Collective or any subsidiary of Collective
on or before the Effective Time with respect to liabilities and claims (and
related expenses including fees and disbursements of counsel) made against
them resulting from their service as such prior to the Effective Time in
accordance with and subject to the requirements and other provisions of the
Summit Restated Certificate of Incorporation and By-Laws in effect on the date
the Merger Agreement was executed and applicable provisions of law to the same
extent as Summit is obliged thereunder to indemnify and advance expenses to
its own directors and officers with respect to liabilities and claims made
against them resulting from their service to Summit.
   
  In the Merger Agreement, Summit also agreed that, subject to Collective's
covenant to take all requisite action to preserve its rights under its
directors and officers liability insurance policies with respect to matters
occurring prior to the Effective Time (other than matters arising in
connection with the Merger Agreement and the transactions contemplated
thereby), for a period of six (6) years after the Effective Time, Summit would
use its best efforts to provide to the persons who served as directors or
officers of Collective or any subsidiary of Collective on or before the
Effective Time insurance against liabilities and claims (and related expenses)
made against them resulting from their service prior to the Effective Time
comparable in coverage to that provided by Summit to its own directors and
officers, but, if not available on commercially reasonable terms, then
coverage substantially similar in all material respects to the insurance
coverage provided to them in such capacities on the date of the Merger
Agreement ("Comparable Coverage"); provided that in no event is Summit
required to expend in the aggregate for the six years of post-Merger coverage
more than 200% of the amount expended by Collective prior to the execution of
the Merger Agreement for one year of coverage ("Coverage Amount"). Summit has
agreed to use its best efforts to obtain as much comparable insurance as is
available for the Coverage Amount if it is unable to maintain or obtain
Comparable Coverage. Collective must renew any existing insurance or purchase
any "discovery period" insurance provided for under existing insurance at
Summit's request.     
 
Board of Directors
 
  As provided for in the Merger Agreement, upon consummation of the Merger,
Thomas H. Hamilton, Chairman of Collective, will be appointed to the Summit
Board to serve as a member of that class of Summit
 
                                      36
<PAGE>
 
directors with a term of office expiring at the 2000 Annual Meeting of
Shareholders of Summit and one other person chosen by the Board of Directors
of Summit from among the persons serving as directors of Collective on the
date of the Merger Agreement will be appointed to serve as a member of that
class of Summit Board with a term of office expiring at the 1999 Annual
Meeting of Shareholders of Summit. At this time such person has not been
chosen.
 
Employment and Change of Control Agreements
   
  Thomas H. Hamilton is party to an employment agreement with each of
Collective and Collective Bank which provide for Mr. Hamilton to be employed
as Chairman of the Board and Chief Executive Officer of, respectively,
Collective and Collective Bank for a three year term. Each agreement (and the
related three year term of employment) automatically renews each year on its
October 1 anniversary date unless the Board of Collective or Collective Bank,
as the case may be, elects not to renew its agreement. The agreements provide
that upon a termination of Mr. Hamilton's employment with either Collective or
Collective Bank (other than due to death or for "cause", as defined in the
agreements) following a "change of control" (as defined in the agreements) of
Collective or Collective Bank (all during the term of the agreement), Mr.
Hamilton is entitled to receive severance pay in the amount of the greater of
the payments due for the remaining term of the agreement or three times the
preceding year's base salary, including bonus and any other cash or deferred
compensation paid or to be paid to Mr. Hamilton during such year, and the
amount of any contributions made or to be made to any employee benefit plan on
behalf of Mr. Hamilton during such year, except to the extent such benefits
are otherwise payable upon a "Change of Control". In addition, for 36 months
Mr. Hamilton is entitled to continuation of life, medical, dental and
disability coverage substantially identical to coverage maintained prior to
termination of employment. The Merger will constitute a "Change of Control"
for purposes of Mr. Hamilton's employment agreements. If, pursuant to the
provisions described above, payments were required to be made to Mr. Hamilton,
the estimated amount of such payments would be $1,561,956. The employment
agreement between Mr. Hamilton and Collective provides that all payments due
to Mr. Hamilton thereunder shall be reduced by the amount of payments made
pursuant to the employment agreement between Collective Bank and Mr. Hamilton.
       
  Collective Bank is a party to a change of control (termination) agreement
with each of Edward J. McColgan, Scott T. Page, Arthur L. Foster, Bernard H.
Berkman, Albert A. Kuehner, Harry G. Miller, Robert D. Pierson and John E.
Palmer, which provide that if the employment of the named executive officer
with Collective Bank (or a successor) is terminated for reasons other than (i)
death or retirement of the executive, or (ii) by Collective Bank (or a
successor) for "cause" (as defined in the agreements) or due to the disability
of the executive, or is terminated by the executive for "good reason" (as
defined in the agreements), then in such case the named executive officer is
entitled to receive a lump sum payment equal to the aggregate of periodic
salary and incentive payments the executive officer would otherwise have
earned through the term of his agreement or for one year, whichever is
greater, and any incentive payments or salary earned prior to the date of
termination but not paid, plus life, disability, accident and health insurance
benefits for the greater of one year or the remaining term of the agreement.
Each agreement currently provides for a term ending December 31, 1998, unless
prior thereto a "change of control" (as defined in the agreements) occurs, in
which case the term is automatically extended to December 31, 1999. The Merger
will constitute a "Change of Control" for purposes of these agreements.
Messrs. McColgan, Page, and Berkman (the executive officers included in the
summary compensation table in Collective's most recent annual meeting proxy
statement) are currently paid salary at the annual rates of $186,900, $142,000
and $127,628, respectively, and have target annual incentives of 25%, 20% and
15% of base salary, respectively.     
 
  Pursuant to the Merger Agreement, Summit has agreed to assume the
obligations of Collective under the foregoing agreements.
 
Collective Stock Option Plans
   
  As described under "THE MERGER--Conversion of Collective Stock Options,"
Original Options outstanding at the Effective Time will be automatically
converted into New Options, subject to the terms of the     
 
                                      37
<PAGE>
 
   
particular Collective Option Plan and Grant Agreement governing the Original
Option, including terms and provisions governing exercises. The number of
shares covered by the New Options and the exercise price thereof will be set
by, respectively, multiplying the number of shares covered by, and dividing
the exercise price of, the Original Option by, the Exchange Ratio. Pursuant to
the terms of the Incentive Plan and Grant Agreements thereunder, Original
Options granted under the Incentive Plan will be converted into immediately
exercisable New Options whether or not the Original Option was exercisable.
       
  The following table sets forth certain information relating to Original
Options held by Messrs. Hamilton, McColgan, Page and Berkman and all directors
and executive officers of Collective as a group as follows: (i) the number of
Original Options held by such persons; (ii) the number of Original Options
held by such persons that are currently exercisable; (iii) the number of
unexercisable Original Options held by such persons that will be converted
into exercisable New Options at the Effective Time; (iv) the weighted average
exercise price for currently exercisable Original Options; (v) the weighted
average exercise price for unexercisable Original Options that will be
converted into exercisable New Options at the Effective Time; and (vi) the
aggregate net unrealized value of all Original Options based on the number of
shares of Summit Common covered by, and the exercise price of, the New Options
into which the Original Options are convertible and using the last sale price
of a share of Summit Common on May 30, 1997 of $49.38 as the market price for
purposes of the calculation.

Directors Deferred Compensation Plan     
   
  Collective maintains a Directors Deferred Compensation Plan which allows a
director to defer receipt of directors fees until such time as the director's
service on the Collective Board terminates. The plan pays interest at a rate
set from time to time by Collective. Such deferred payments represent an
unfunded obligation of Collective. Prior to the Effective Time, Collective
will contribute to a grantor trust approximately $1,522,000, in order to
provide a source of funds to assist Collective in meeting its liabilities
under the plan.     
 
Severance Pay Provision
 
  The Merger Agreement provides that any employee of Collective or a
subsidiary of Collective at the Effective Time whose employment is terminated
by Summit, other than for cause, within twelve (12) months of the Effective
Time is entitled to receive a severance payment equal to the sum of: (i) the
greater of (A) four times the employee's gross weekly salary or (B) the
product of such employee's gross weekly salary multiplied by two times the
number of full years of service completed by such employee prior to the
termination of employment; and (ii) in the event less than 60 days advance
notice of termination is provided to a particular employee, the product of (A)
the difference of 60 minus the number of days of advance notice of termination
received by a particular employee (a negative difference being treated as
zero) and (B) the employee's annual salary rate at the time of termination of
employment divided by 365. However, no employee of Collective or a subsidiary
of Collective shall be eligible to receive the foregoing payment if such
employee is offered a position by Summit which is similar in job content to
the position held by such employee with Collective or a subsidiary and is
located at a reasonably accessible location.
 
                                      38

THE MERGER AGREEMENT
 
Amendment
 
  Collective and Summit may jointly amend the Merger Agreement at any time;
provided, however, that, after the Special Meeting, no amendment may reduce
the amount of, or change the form of consideration to be received by
Collective stockholders unless such modification is submitted to a vote of
Collective stockholders.
 
Collective Covenants
 
  Pursuant to the Merger Agreement, Collective has covenanted, among other
things, that, until termination of the Merger Agreement, Collective will
advise Summit of any material adverse change in Collective's business and of
certain other circumstances, and the business of Collective and its
subsidiaries will be carried on substantially in the same manner as prior to
the execution of the Merger Agreement. Furthermore, until termination of the
Merger Agreement, without the prior written consent of Summit, Collective will
not declare or pay any dividend other than a quarterly cash dividend at a rate
up to $.25 per share, and will refrain from taking certain other actions,
including certain actions relating to changes in its capital stock, the
incurrence of liabilities and the issuance of capital stock.
 
  Collective also has agreed that, until termination of the Merger Agreement
or the Effective Time, neither Collective nor any of its subsidiaries nor any
of the officers or directors of Collective or its subsidiaries shall, and that
Collective shall direct and use its best efforts to cause its employees,
agents, affiliates and representatives (including investment bankers, brokers,
financial or investment advisors, attorneys or accountants retained by
Collective or any of its subsidiaries) not to, initiate, solicit or encourage,
directly or indirectly, any inquiries, proposals or offers with respect to, or
engage in any negotiations or discussions with any person or provide any
nonpublic information or authorize or enter into any agreement or agreement in
principle concerning, or recommend, endorse or otherwise facilitate any effort
or attempt to induce or implement any Acquisition Proposal (as defined below);
provided, however, that the Board of Directors of Collective may furnish or
cause to be furnished nonpublic information and may participate in discussions
directly or through its representatives concerning an Acquisition Proposal if
the Board of Directors of Collective, after having consulted with outside
counsel and been advised of its legal rights, has determined that the failure
to provide such nonpublic information or participate in such discussions would
cause the members of the Board of Directors to breach their fiduciary duties
under applicable laws, and, provided further, that Collective shall first
obtain a confidentiality agreement in customary form and containing at least
the confidentiality provisions set forth in the Merger Agreement. "Acquisition
Proposal" is defined as any offer, including an exchange offer or tender
offer, or proposal concerning a merger, consolidation, business combination or
takeover transaction involving Collective or any of its subsidiaries, or the
acquisition of any assets (except as otherwise permitted under the Merger
Agreement) or any securities of Collective or any of its subsidiaries. In
addition, Collective has agreed to notify Summit, by telephone call to its
chief executive officer or general counsel, promptly upon receipt of any
communication with respect to a proposed Acquisition Proposal with another
person or receipt of a request for information from any governmental or
regulatory authority with respect to a proposed acquisition of Collective or
any of its subsidiaries or assets by another party and to deliver as soon as
possible by facsimile transmission to such Summit officer a copy of any
document relating thereto promptly after any such document is received by
Collective.
 
  In order to ensure that Collective stockholders would be paid at least one,
but no more than one, dividend in each calendar quarter between the date of
the Merger Agreement and the Effective Time, Collective agreed in the Merger
Agreement to coordinate with Summit the declaration of any dividends and the
setting of any dividend record or payment dates.
 
Summit Covenants
 
  Pursuant to the Merger Agreement, Summit has covenanted, among other things,
that, until termination of the Merger Agreement, Summit will advise Collective
of any material adverse change in Summit's business and certain other
circumstances.
 
                                      39

Conditions to the Merger; Termination
 
  The obligations of both parties to consummate the Merger are subject to the
satisfaction of certain conditions including: (1) approval of the Merger
Agreement by the requisite vote of the holders of Collective Common; (2)
receipt of all required regulatory approvals by Summit and Collective without
restrictions or limitations, that, in the reasonable opinion of Summit or
Collective, would materially adversely affect the financial condition of
Summit following the consummation of the Merger and the expiration of any
waiting periods required by such approvals; (3) effectiveness of the
registration statement; (4) the receipt by Summit and Collective of an opinion
from Thomson Coburn as to certain federal income tax consequences of the
Merger; (5) the NYSE has indicated that the shares of Summit Common to be
issued in the Merger are to be listed on the NYSE, subject to official notice
of issuance; (6) the absence of material litigation; (7) the absence of
regulatory agreements relating to the parties; (8) the delivery of officers'
certificates by Collective and Summit; and (9) other customary conditions
described in the Merger Agreement. In addition, the obligation of Summit to
consummate the Merger is subject to the receipt by Summit of Affiliate
Agreements from a sufficient number of Collective Affiliates, such that, in
the reasonable opinion of Summit, based upon consultation with its independent
accounting firm, the Merger may be accounted for on a pooling-of-interests
basis and the receipt of a letter from KPMG Peat Marwick LLP, independent
auditors for Summit, to the effect that, based on the facts known to such
accountants, the Merger will qualify for pooling-of-interests accounting
treatment if consummated in accordance with the Merger Agreement. Any of such
conditions may be waived by the party for whose benefit the condition was
included. However, the Merger will not be consummated without the receipt of
the requisite stockholder and regulatory approvals.
   
  Either party may terminate the Merger Agreement if (1) Collective
stockholders, in a vote on the Merger Agreement at a meeting held for such
purpose, fail to approve the Merger Agreement by the requisite vote, (2) the
other party materially breaches a warranty, representation or covenant and
such breach is not cured or capable of being cured within 30 days of the
giving of written notice thereof (provided that the terminating party is not
in material breach of any representation, warranty, covenant or other
agreement), (3) on the date for Closing designated by Summit in the Closing
Notice, all the conditions precedent to such parties' obligations to close are
not met, or (4) the Closing is not consummated on or before January 1, 1998,
provided, however, that a party does not have the termination right described
by this clause (4) if the failure to close by January 1, 1998 is due solely to
its failure to perform or observe an agreement which the Merger Agreement
requires it to perform or observe by the Closing Date. In addition, the
parties may terminate the Merger Agreement at any time by mutual agreement.
    
       
Expenses
 
  Should either party terminate the Merger Agreement because the other party
has materially breached a warranty, representation or covenant or because the
other party has not met its conditions of closing, then the terminating party
shall be reimbursed by the defaulting party for the terminating party's out-
of-pocket expenses reasonably incurred in connection with the Merger
Agreement, including counsel fees, printing fees and filing fees, but
excluding any brokers', finders' or investment bankers' fees. In the event
that the Merger Agreement is terminated by either party other than under
circumstances described in the immediately preceding sentence, each party is
mutually released and discharged from liability to the other party or to any
third party thereunder, and no party is liable to any other party for any
costs or expenses incurred in connection with the Merger Agreement, except
that each party is responsible for one-half of the expenses incurred in
connection with the printing of this Proxy Statement-Prospectus and the
Registration Statement and the filing fees with the Commission, the Federal
Reserve Board and the NYSE.
 
CHARTER AND BY-LAWS OF SURVIVING CORPORATION
 
  Pursuant to the Merger Agreement, the Restated Certificate of Incorporation
and By-Laws of Summit, as in effect at the Effective Time, will be the
Restated Certificate of Incorporation and By-Laws of the Surviving Corporation
in the Merger unless and until amended.
 
                                      40
<PAGE>
 
BOARD OF DIRECTORS AND OFFICERS OF SURVIVING CORPORATION
 
  The Merger Agreement provides that the Board of Directors of the Surviving
Corporation will consist of (i) the members of the Board of Directors of
Summit at the Effective Time, (ii) Thomas H. Hamilton, Chairman and Chief
Executive Officer of Collective, provided he is still serving as such at the
Effective Time and is available for service, who shall be designated to serve
as a member of that class of Summit directors with a term of office expiring
at the 2000 Annual Meeting of the Shareholders of Summit and (iii) one other
person chosen by the Board of Directors of Summit from among those persons
serving as Collective directors on the date of the Merger Agreement and who
continue to serve as Collective directors through the Effective Time, who
shall be designated to serve as a member of that class of Summit directors
with a term of office expiring at the 1999 Annual Meeting of the Shareholders
of Summit.
 
  The Merger Agreement also provides that the officers of Summit at the
Effective Time will continue to be the officers of the Surviving Corporation.
 
NO DISSENTERS' RIGHTS
 
  Under applicable Delaware law, no dissenters' rights of appraisal are
available to holders of Collective Common in connection with the Merger.
 
NEW YORK STOCK EXCHANGE LISTING
 
  Summit has agreed in the Merger Agreement to use its best efforts to cause
the shares of Summit Common to be issued in the Merger to be listed on the
NYSE. The NYSE's indication that such shares of Summit Common are to be listed
on the NYSE (subject to official notice of issuance) is a condition to the
consummation of the Merger.
 
ACCOUNTING TREATMENT
 
  It is anticipated that the Merger, when consummated, will be accounted for
as a pooling-of-interests and it is a condition to Summit's obligations to
consummate the Merger that Summit receives a letter from KPMG Peat Marwick
LLP, independent auditors of Summit, to the effect that the Merger qualifies
for such accounting treatment. Under this method of accounting, the historical
book values of the assets, liabilities and stockholders' equity of Collective,
as reported on its Consolidated Balance Sheet, will be carried over onto the
Consolidated Balance Sheet of Summit and no goodwill or other intangible
assets will be created. Summit will include in its Consolidated Statement of
Income the consolidated results of operations of Collective for the entire
fiscal year in which the consummation of the Merger occurs and will combine
and restate its results of operations for prior periods to include the
reported consolidated results of operations of Collective for prior periods.
 
CERTAIN FEDERAL INCOME TAX CONSEQUENCES OF THE MERGER
 
  The following discussion is based upon an opinion of Thompson Coburn,
special counsel to Summit ("Counsel"), and except as otherwise indicated,
reflects Counsel's opinion. The discussion is a summary of the material United
States federal income tax ("federal income tax") consequences of the Merger to
certain Collective stockholders and does not purport to be a complete analysis
or listing of all potential tax considerations or consequences relevant to a
decision whether to vote for the approval of the Merger Agreement. The
discussion does not address all aspects of federal income taxation that may be
applicable to Collective stockholders in light of their status or personal
investment circumstances, nor does it address the federal income tax
consequences of the Merger that are applicable to Collective stockholders
subject to special federal income tax treatment including (without limitation)
foreign persons, insurance companies, tax-exempt entities, retirement plans,
dealers in securities, persons who acquired their Collective Common pursuant
to the exercise of employee stock options or otherwise as compensation, and
persons who hold their Collective Common as part of a "straddle," "hedge" or
"conversion transaction." In addition, the discussion does not address the
effect of any applicable state, local or foreign tax laws, or the effect of
any federal tax laws other than those pertaining to the federal income tax. As
a result, each Collective stockholder is urged to consult his or her own tax
advisor to
 
                                      41
<PAGE>
 
determine the specific tax consequences of the Merger to such stockholder. The
discussion assumes that shares of Collective Common are held as capital assets
(within the meaning of Section 1221 of the Code) at the Effective Time.
 
  Collective has received an opinion from Counsel to the effect that, assuming
the Merger occurs in accordance with the Merger Agreement, the Merger will
constitute a "reorganization" for federal income tax purposes under Section
368(a)(1) of the Code, with the following federal income tax consequences:
 
    (1) Collective stockholders will recognize no gain or loss as a result of
  the exchange of their Collective Common solely for shares of Summit Common
  pursuant to the Merger, except with respect to Cash in Lieu Amounts with
  regard to fractional shares, if any, as discussed below.
 
    (2) The aggregate adjusted tax basis of the shares of Summit Common
  received by each Collective stockholder in the Merger (including any
  fractional share of Summit Common deemed to be received, as described in
  paragraph 4 below) will be equal to the aggregate adjusted tax basis of the
  shares of Collective Common surrendered.
 
    (3) The holding period of the shares of Summit Common received by each
  Collective stockholder in the Merger (including any fractional share of
  Summit Common deemed to be received, as described in paragraph 4 below)
  will include the holding period of the shares of Collective Common
  exchanged therefor.
 
    (4) A Collective stockholder who receives the Cash In Lieu Amount with
  regard to a fractional share of Summit Common will be treated as if the
  fractional share had been received by such stockholder in the Merger and
  then redeemed by Summit in return for the Cash In Lieu Amount. The receipt
  of such cash will cause the recipient to recognize capital gain or loss
  equal to the difference between the amount of cash received and the portion
  of such holder's adjusted tax basis in the shares of Summit Common
  allocable to the fractional share.
 
  Counsel's opinion is subject to the conditions and customary assumptions
that are stated therein and relies upon various representations made by
Summit, Collective, and certain stockholders of Collective. If any of these
representations or assumptions is inaccurate, the tax consequences of the
Merger could differ from those described herein. Counsel's opinion is also
based upon the Code, regulations proposed or promulgated thereunder, judicial
precedent relating thereto, and current administrative rulings and practice,
all of which are subject to change. Any such change, which may or may not be
retroactive, could alter the tax consequences discussed herein. The receipt of
Counsel's opinion again as of the Closing Date is a condition to the
consummation of the Merger. An opinion of counsel, unlike a private letter
ruling from the Internal Revenue Service ("Service"), has no binding effect.
The Service could take a position contrary to Counsel's opinion and, if the
matter were litigated, a court may reach a decision contrary to the opinion.
Neither Summit nor Collective has requested an advance ruling as to the
federal income tax consequences of the Merger, and the Service is not expected
to issue such a ruling.
 
  THE FOREGOING IS A SUMMARY OF THE MATERIAL FEDERAL INCOME TAX CONSEQUENCES
OF THE MERGER TO CERTAIN COLLECTIVE STOCKHOLDERS AND DOES NOT TAKE INTO
ACCOUNT THE PARTICULAR FACTS AND CIRCUMSTANCES OF EACH COLLECTIVE
STOCKHOLDER'S TAX STATUS AND ATTRIBUTES. AS A RESULT, THE FEDERAL INCOME TAX
CONSEQUENCES ADDRESSED IN THE FOREGOING DISCUSSIONS MAY NOT APPLY TO EACH
COLLECTIVE STOCKHOLDER. ACCORDINGLY, EACH COLLECTIVE STOCKHOLDER SHOULD
CONSULT HIS OR HER OWN TAX ADVISOR REGARDING THE SPECIFIC TAX CONSEQUENCES OF
THE MERGER, INCLUDING THE APPLICATION AND EFFECT OF FEDERAL, STATE, LOCAL AND
OTHER TAX LAWS AND THE POSSIBLE EFFECTS OF CHANGES IN FEDERAL AND OTHER TAX
LAWS.
 
RESALE OF SUMMIT COMMON
 
  The shares of Summit Common into which shares of Collective Common are
converted on the Effective Date will be freely transferable under the
Securities Act except for shares issued to any stockholder who may be
 
                                      42
<PAGE>
 
   
deemed to be a Collective Affiliate for purposes of Rule 145 under the
Securities Act as of the date of Special Meeting or an affiliate of Summit for
purposes of Rule 144 under the Securities Act thereafter. Collective
Affiliates may not sell their shares of Summit Common 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 under
the Securities Act or another applicable exemption from the registration
requirements of the Securities Act. Collective Affiliates who may be deemed to
be affiliates of Summit after the Merger may not sell their shares of Summit
Common except pursuant to an effective registration statement under the
Securities Act covering such shares or in compliance with Rule 144 under the
Securities Act or another applicable exemption from the registration
requirements of the Securities Act. Persons who may be deemed to be affiliates
of a company under Rules 144 and 145 generally include individuals or entities
that control, are controlled by or are under common control with the company
and may include certain officers and directors of such company as well as
principal stockholders thereof.     
   
  Collective agreed in the Merger Agreement to use its best efforts to cause
each director, executive officer and other person deemed in the opinion of
Collective's counsel to be a Collective Affiliate to enter into an agreement
with Summit providing that such persons agree to be bound by the restrictions
imposed by the pooling-of-interest accounting rules and Rule 145. The rules
regarding pooling-of-interests accounting treatment include restrictions on
sales or other dispositions of Summit Common or Collective Common by
affiliates of either Summit or Collective during the period commencing 30 days
prior to the Merger and ending at the time of the publication of financial
results covering at least 30 days of combined operations of Summit and
Collective.     
   
DIFFERENCES IN SHAREHOLDERS' RIGHTS     
   
  The rights of Collective stockholders, which are determined by Delaware
corporation law and the Restated Certificate of Incorporation and By-Laws of
Collective, differ from the rights accorded Summit shareholders, which are
determined by New Jersey corporation law and the Restated Certificate of
Incorporation and By-Laws of Summit. Some of the differences in shareholders'
rights are attributable to differences between the corporation law of
Delaware, the state of Collective's incorporation, and the corporation law of
New Jersey, the state of Summit's incorporation. The remaining differences in
shareholders' right are attributable to differences between the Restated
Certificate of Incorporation and By-Laws of Collective and the Restated
Certificate of Incorporation and By-Laws of Summit. Certain of the rights of
Collective stockholders described below which are provided by Delaware
corporation law or contained in the Restated Certificate of Incorporation or
By-Laws of Collective and which are not provided by New Jersey corporation law
or contained in the Restated Certificate of Incorporation or By-Laws of Summit
are deemed to have an anti-takeover effect and will not be available to
Collective stockholders as Summit shareholders; however, certain rights
provided for by New Jersey corporation law or the Restated Certificate of
Incorporation or By-Laws of Summit are also deemed to have an anti-takeover
effect and will be available to Collective stockholders only after becoming
Summit shareholders. The following is a summary discussion of the most
significant differences in shareholders' rights. This summary is qualified in
its entirety by reference to the corporation laws of Delaware and New Jersey
and the governing documents of Collective and Summit referred to above.     
 
Comparison of Certificates of Incorporation and By-Laws
 
Classified Board and Cumulative Voting
   
  COLLECTIVE. The Restated Certificate of Incorporation and By-Laws of
Collective divide the Collective Board into three classes, as nearly equal in
number as possible, with each class of directors serving a staggered term of
three years. The By-Laws of Collective provide that the Collective Board shall
consist of nine directors. There are three directors in each class. Directors
are elected by a plurality of votes cast. Stockholders of Collective are
entitled to cumulate their votes in the election of directors and cast for one
candidate a number of votes equal to the number of directors to be elected
multiplied by the number of shares held, or distribute their shares between
two or more candidates.     
 
 
                                      43
<PAGE>
 
  SUMMIT. The Restated Certificate of Incorporation of Summit provides that
the Summit Board shall consist of not less than five and not more than forty
persons and divides the Summit Board into three classes, with each class of
directors serving a staggered term of three years. Each class of directors
must consist, as nearly as possible, of one third of the number of directors
constituting the entire Summit Board. Directors are elected by a plurality of
votes cast by shares entitled to vote. Presently there are six directors in
each class. Holders of Summit Common may not cumulate their votes in elections
of directors.
 
  The Restated Certificate of Incorporation of Summit further requires that
resolutions increasing the number of directors be approved by 80% of, as the
case may be, directors holding office or shares of capital stock of Summit
entitled to vote generally in the election of directors, voting as a single
class.
 
  The Restated Certificate of Incorporation of Summit also provides that the
affirmative vote of the holders of 80% or more of the combined voting shares
of Summit, voting as a single class, is required to amend, repeal or take any
action inconsistent with the classified board of directors or the requirement
for an 80% affirmative vote to approve any increase in the number of
directors. The effect of these provisions is to make it difficult for persons
other than those negotiating directly with the Summit Board to acquire seats
on the Summit Board and obtain control of Summit.
 
Meetings and Consents
 
  COLLECTIVE. Collective's By-Laws provide that a special meeting of
stockholders may be called by the Chairman of the Board, by the President or
by a majority of the Board of Directors and shall be called by the Chairman of
the Board, the President or the Secretary upon the written request of the
holders of not less than one-tenth of all the outstanding capital stock
entitled to vote at the meeting. Under the Collective Restated Certificate of
Incorporation and By-Laws, any action required or permitted to be taken by
stockholders must be effected at a duly called annual or special meeting and
may not be effected by consent in writing of stockholders.
 
  SUMMIT. Under Summit's By-Laws, except as otherwise provided by law, special
meetings may be called only by the Chairman, Vice Chairman, President or
majority of the entire Board. The Restated Certificate of Incorporation of
Summit requires that, subject to the rights of holders of any series of
Preferred Stock or other class or series of stock having preference over the
Summit Common as to dividends or upon liquidation, all actions by the
shareholders of Summit be taken exclusively at a duly called annual or special
meeting of Summit's shareholders or by the unanimous, but not less than
unanimous, written consent of the shareholders. An additional provision in the
Restated Certificate of Incorporation of Summit provides that the affirmative
vote of the holders of 80% or more of the combined voting shares of Summit,
voting as a single class, is required to amend, alter, repeal or take any
action inconsistent with this requirement. Under the Summit By-Laws, except as
otherwise required by law or Summit's Restated Certificate of Incorporation,
all actions by shareholders must be taken at a meeting unless the Board
determines that such action shall be taken by written consent.
 
Shareholder Rights Plan
 
  SUMMIT SHAREHOLDER RIGHTS PLAN. Summit has in effect a shareholder rights
plan pursuant to which holders of shares of Summit Common possess one
preferred stock purchase right for each share of Summit Common held by them.
Each preferred stock purchase right entitles the holder to buy, as of the
close of business on the tenth day following the occurrence of certain
takeover-related events ("effective time"), one hundredth of a share of a new
series of Preferred Stock, designated the Series R Preferred Stock, at $90 per
one hundredth share ("exercise price"), with full shares having rights per
share equal to 100 times the rights of Summit Common with respect to voting,
dividends and distributions upon liquidation or merger as well as entitling
the holder to an additional preferential dividend. Upon the occurrence of
certain subsequently occurring events, holders of the preferred stock purchase
rights become entitled to purchase either shares of the Series R Preferred
Stock (if not already purchased) or a number of shares of the "acquiring
person" (as defined in the rights plan) equal in market value to twice the
exercise price of the preferred stock purchase right. The Summit Board has the
power to redeem the preferred stock purchase rights at any time but, after the
preferred stock purchase rights
 
                                      44
<PAGE>
 
become exercisable, it may do so only upon the majority vote of non-management
directors in connection with a business combination it has approved. For a
further description of Summit's shareholder rights plan, see "DESCRIPTION OF
SUMMIT CAPITAL STOCK--Shareholder Rights Plan." The combination of prohibitive
dilution of the acquiring person's share value and the power of the Summit
Board to redeem the preferred stock purchase rights is intended to encourage
potential acquiring persons to negotiate with the Summit Board with respect to
the terms of any acquisition or business combination and to the extent
possible, discourage or defeat abusive partial or two-tiered acquisition
proposals.
 
  Collective has not adopted a stockholder rights plan.
 
Nominations to the Board, Shareholder Proposals and Conduct of Meeting
 
  COLLECTIVE. Pursuant to Collective's By-Laws, nominations for election to
the Board of Directors may be made by the Board of Directors or by any
stockholder entitled to vote for the election of directors. Collective
stockholders may nominate directors for election by providing written notice
to Collective's Secretary delivered or mailed and received at the offices of
Collective not less than thirty (30) days prior to the meeting (unless less
than 40 days notice or prior disclosure of the meeting is given, in which case
such nomination must be mailed or delivered not later than ten days following
the notice or public disclosure). The Collective officer presiding at the
meeting shall disregard any stockholder nomination to the Collective Board
which is not made in accordance with the By-Laws.
 
  SUMMIT. The By-Laws of Summit contain provisions that empower the Summit
Board to adopt rules, regulations and procedures governing meetings of Summit
shareholders and empower the chairman of a meeting of Summit shareholders,
subject to the rules and regulations adopted by the Summit Board, to adopt
such rules, regulations and procedures and to take such actions that the
chairman deems necessary, appropriate or convenient for the proper conduct of
a stockholder meeting. The Summit By-Laws also contain provisions that (1)
establish rules governing nominations for director and shareholder proposals
made at meetings of shareholders and, in general, empower the chairman of an
annual meeting to disallow nominations and shareholder proposals that are not
made at least 80 days in advance of the anniversary of the preceding year's
annual meeting or that otherwise fail to comply with the requirements of the
By-Laws and (2) establish rules governing nominations for directors made at
special meetings of shareholders and empower the chairman of a special meeting
to disallow nominations that are not made at least 70 days prior to such
special meeting or the 10th day following the day on which public announcement
of such special meeting is first made or that otherwise fail to comply with
the requirements of the By-Laws.
   
Vote Required for Charter and By-Law Amendments     
 
  COLLECTIVE. The Collective Restated Certificate of Incorporation provides
the affirmative vote of the holders of a majority of the voting power of all
outstanding shares of capital stock of Collective entitled to vote thereon is
required to amend the Restated Certificate of Incorporation of Collective.
Pursuant to Collective's Restated Certificate of Incorporation and By-Laws,
the By-Laws may be altered, amended or repealed by the affirmative vote of the
holders of a majority of the voting power of all outstanding shares of capital
stock of Collective. The Collective Restated Certificate of Incorporation also
authorizes a majority of the Board of Directors to adopt, amend or repeal the
By-Laws.
   
  SUMMIT. As discussed above, the Restated Certificate of Incorporation of
Summit requires that certain provisions relating to increases in the number of
directors (which number may also be increased by the Board), changes to the
classified board provision and changes to the provision requiring that actions
by shareholders be effected at an annual or special meeting or by unanimous
written consent, receive the affirmative vote of holders of 80% of the
combined voting shares of Summit, voting as a single class. Otherwise,
pursuant to the New Jersey Business Corporation Act, the Restated Certificate
of Incorporation may be amended, in general, by the affirmative vote of a
majority of the votes cast. The By-Laws of Summit provide for amendments upon
two-thirds     
 
                                      45
<PAGE>
 
vote of the Board of Directors. Under the New Jersey Business Corporation Act,
by-laws made by a corporation's board may be altered or repealed and new by-
laws made by the shareholders.
 
Removal of Directors
   
  COLLECTIVE. Under the Collective Restated Certificate of Incorporation, the
Board of Directors, or any individual director, may be removed for cause by
the affirmative vote of the holders of a majority of the shares of capital
stock entitled to vote for the election of directors; provided, however, that
if less than the entire board is to be removed no director may be removed if
the votes cast against removal would be sufficient to elect a director if such
votes were cumulated.     
   
  SUMMIT. The Summit Restated Certificate of Incorporation contains no
specific provisions with respect to removal of directors (other than for
directors elected by holders of preferred stock). Under the New Jersey
Business Corporation Act, with respect to a classified board, unless otherwise
provided in the certificate of incorporation, directors may be removed by
shareholders for cause only by the affirmative vote of the majority of votes
cast by the holders entitled to vote thereon.     
 
Authorized Shares
 
  COLLECTIVE. Collective has 37,000,000 authorized shares of common stock, par
value $.01 per share and 2,500,000 shares of Preferred Stock, par value $.01
per share. As of March 31, 1997, there were 20,446,519 shares of Collective
Common outstanding and no shares of Preferred Stock outstanding. Collective's
Restated Certificate of Incorporation does not provide for preemptive rights
to attach to the ownership of Collective Common.
 
  SUMMIT. The Restated Certificate of Incorporation of Summit authorizes the
issuance of 260,000,000 shares of Summit Common and 4,000,000 shares of
preferred stock, no par value. As of March 31, 1997, there were 98,450,950
shares of Summit Common outstanding and 1,000,000 shares (subsequently
increased to 1,500,000 shares) of Summit Series R Preferred created in
Summit's Restated Certificate of Incorporation for issuance under the
Shareholder Rights Plan of Summit. The Restated Certificate of Incorporation
of Summit and the New Jersey Business Corporation Act authorize the Summit
Board to amend the Restated Certificate of Incorporation without stockholder
concurrence to divide the authorized shares of preferred stock into series, to
determine the designations and the number of shares of any such series, and to
determine the relative voting, dividend, conversion, redemption, liquidation
and other rights, preferences and limitations of the authorized shares of
preferred stock. No preemptive rights attach to the ownership of Summit
Common.
 
Indemnification; Limitation of Liability
 
  COLLECTIVE. Collective's Restated Certificate of Incorporation provides that
Collective shall indemnify each person who is made a party to a "proceeding",
as such term is defined therein, by reason of the fact that such person is or
was a director or officer of the company or is or was serving at the request
of the company as a director, officer, employee or agent of another
corporation, for expenses and liabilities incurred in connection with such
proceedings to the fullest extent permitted by the Delaware General
Corporation Law, including advancement of expenses, and authorizes Collective
to purchase insurance for officers, directors and corporate agents.
Collective's Restated Certificate of Incorporation also provides that a
director of Collective shall not be personally liable to Collective or its
stockholders for monetary damages for breach of a fiduciary duty, except for
any liability: (i) for breach of the director's duty of loyalty to the
corporation or its stockholders; (ii) for acts or omissions not in good faith
or involving intentional misconduct or knowing violation of law; (iii) for
unlawful payment of dividends, stock repurchases or redemptions; or (iv) for
transactions resulting in receipt by such director of an improper personal
benefit. The Collective Restated Certificate of Incorporation also provides
for further elimination or limitation of liability to the fullest extent to
which the Delaware General Corporation Law may permit if amended.
 
 
                                      46
<PAGE>
 
   
  SUMMIT. Summit's By-Laws provide that corporate agents (which term includes
directors, officers and employees) of Summit shall be indemnified and held
harmless by Summit to the fullest extent authorized by the laws of the State
of New Jersey against expenses and liabilities arising in connection with
actions performed by the corporate agent on behalf of Summit and that Summit
may maintain insurance for corporate agents against liabilities and expenses.
Summit's Restated Certificate of Incorporation limits the personal liability
of a director or officer for damages for breach of any duty owed to the
company or its shareholders except for liability for breach of duty based upon
an act or omission: (i) in breach of such person's duty of loyalty to the
corporation or its shareholders (ii) not in good faith or involving a knowing
violation of the law or (iii) resulting in receipt by such person of an
improper personal benefit.     
 
Comparison of Corporation Laws
   
  Appraisal Rights in Merger or Consolidation. Under New Jersey corporation
law, unless a certificate of incorporation otherwise provides, a dissenting
shareholder of a New Jersey corporation that is a party to a consolidation, or
that is not the surviving corporation in a merger, or that is the surviving
corporation in a merger requiring shareholder approval, has appraisal rights
with respect to any shares other than (1) shares listed on a national
securities exchange or held of record by not less than 1,000 holders, and (2)
shares in exchange for which, pursuant to the plan of merger or consolidation,
the shareholder will receive cash and/or securities which will be listed on a
national securities exchange or held of record by not less than 1,000 holders.
Summit's Restated Certificate of Incorporation contains nothing which provides
otherwise. Under Delaware corporation law, stockholders of a Delaware
corporation have appraisal rights in a merger or consolidation to which such
corporation is a constituent party, except for certain mergers and
consolidations not requiring any vote by stockholders of the corporation, in
which such corporation is the surviving entity, with respect to any shares
other than shares listed on a national securities exchange or designated as a
national market system security on an interdealer quotation system by the NASD
or held of record by more than 2,000 holders. However, even with respect to
shares so listed or held, appraisal rights exist if, pursuant to the plan of
merger, the stockholder is to receive in exchange for his shares anything
other than stock of the surviving corporation, stock of any other corporation
listed on a national securities exchange or designated as a national market
system security on an interdealer quotation system by the NASD or held of
record by more than 2,000 holders or cash in lieu of fractional shares.     
   
  Appraisal Rights Relating to Disposition of Assets. Under New Jersey
corporation law, a dissenting shareholder in a New Jersey corporation has
appraisal rights in the case of any sale, lease, exchange or other disposition
of all or substantially all of the assets of the corporation not in the usual
or regular course of business as conducted by the corporation (other than for
certain transfers of assets of a wholly owned subsidiary by the parent
corporation), except, unless the certificate of incorporation provides
otherwise, with respect to (1) shares listed on a national securities exchange
or held of record by not less than 1,000 holders, or (2) a transaction
pursuant to a plan of dissolution of the corporation which provides for the
distribution of substantially all of its net assets to shareholders according
to their interests within one year, where such transaction is wholly for cash
and/or securities which will be listed on a national securities exchange or
held of record by not less than 1,000 holders, or (3) a sale pursuant to court
order. Delaware corporation law does not provide for appraisal rights in
connection with dispositions of assets, unless the corporation's certificate
of incorporation provides otherwise. Collective's Restated Certificate of
Incorporation does not provide for appraisal rights in these circumstances.
       
  Class Voting on Merger or Consolidation. Under New Jersey corporation law,
any class or series of shares shall be entitled to vote as a class if the plan
of merger or consolidation contains any provision that, if contained in a
proposed charter amendment, would entitle the class or series to vote as a
class on the amendment. Delaware corporation law provides that any class or
series of shares shall be entitled to vote as a class or series upon a
proposed amendment to the Certificate of Incorporation, whether pursuant to a
plan of merger or consolidation or otherwise, if such amendments make certain
changes to the class or series that adversely affect the rights of the shares
of such class or series.     
 
 
                                      47
<PAGE>
 
  Source of Dividends. Under New Jersey corporation law, dividends may not be
paid if, after giving effect to the dividend, either (1) the corporation would
be unable to pay its debts as they become due in the ordinary course of its
business or (2) the corporation's total assets would be less than its total
liabilities. Under Delaware corporation law, dividends may be paid out of
surplus or, in the absence thereof, out of the net profits of the current
and/or next preceding fiscal year, except where capital represented by stock
enjoying a preference upon the distribution of assets thereby would be
impaired.
   
  Shareholder Approval of Mergers and Consolidations. While shareholder
approval of a merger or consolidation is generally required under both the New
Jersey and the Delaware corporation laws, the New Jersey corporation law
provides that, unless otherwise provided in the corporation's certificate of
incorporation, approval of the shareholders of a surviving corporation in a
merger is not required if (i) the plan of merger does not make an amendment of
the certificate of incorporation of the surviving corporation that would
otherwise require shareholder approval, (ii) the shares outstanding
immediately before the effectiveness of the merger are not changed by the
merger, and (iii) the number of voting or participating shares outstanding
(including shares issuable upon conversion of other securities or upon
exercise of rights or warrants issued pursuant to the merger) after the
merger, after giving effect to the merger, will not exceed by more than 40%
the number of voting and participating shares, as the case may be, of the
surviving corporation outstanding immediately prior to the merger. The
Delaware corporation law has a similar provision but the percentage threshold
is 20% rather than 40% and is with reference to common stock rather than
voting or participating stock (although the Collective Restated Certificate of
Incorporation refers to voting stock with respect to such provision).     
   
  Under New Jersey corporation law, unless otherwise provided in the
corporation's certificate of incorporation, a merger requiring shareholder
approval must be approved by the majority of the votes cast by shareholders
entitled to vote thereon. Under Delaware corporation law, unless otherwise
provided in the certificate of incorporation, a merger requiring stockholder
approval requires the affirmative vote of a majority of the outstanding stock
of the corporation.     
   
  Shareholder Approval of Asset Sales. Under New Jersey corporation law, a
sale of all or substantially all of a corporation's assets outside of the
regular course of business requires the approval of the board of directors and
the affirmative vote of a majority of the votes cast by shareholders entitled
to vote thereon. Under Delaware corporation law, a sale of all or
substantially all of a corporation's assets requires the approval of the board
of directors and the holders of a majority of the outstanding stock of the
corporation entitled to vote thereon.     
 
  Power to Adopt, Amend or Repeal By-laws. Under New Jersey corporation law,
the power to adopt, amend and repeal by-laws of a corporation is vested in the
Board of Directors unless such power is reserved to the shareholders in the
certificate of incorporation, but by-laws made by the Board of Directors may
be amended and repealed and new by-laws adopted by the shareholders and the
shareholders may prescribe in such by-laws that the Board may not amend or
repeal by-laws approved by shareholders. Under Delaware corporation law, the
power to adopt, amend or repeal by-laws of a corporation is vested in the
corporation's stockholders, although the corporation's certificate of
incorporation may also vest such power in the corporation's board of
directors.
 
  Action by Shareholders by Written Consent in Lieu of a Meeting. Under New
Jersey corporation law, except as otherwise provided in a certificate of
incorporation, any action (other than the election of directors and the
approval of a merger, consolidation or sale of substantially all the assets of
the corporation) required or permitted to be taken at a meeting of the
corporation's shareholders, may be taken without a meeting upon the written
consent of shareholders who would have been entitled to cast the minimum
number of votes that would have been necessary to take such action at a
meeting at which all shares entitled to vote thereon were present and voted
(except that the election of directors and the approval of a merger,
consolidation or sale of substantially all the assets of the corporation
requires unanimous written consent of all shareholders). The corporation must
give all shareholders advance notice of such proposed action if the proposed
action involves a merger, consolidation or sale of substantially all of the
assets of a corporation. As discussed earlier, Summit's Restated Certificate
of Incorporation permits action by written consent only where the consent is
unanimous. Under Delaware corporation law, except as otherwise provided in a
company's certificate of incorporation, any action
 
                                      48
<PAGE>
 
required or permitted to be taken at the meeting of a corporation's
stockholders may be taken without a meeting if a written consent, setting
forth the action so taken, is signed by the holders of outstanding shares
having not less that the minimum number of votes that would have been
necessary to take such action at a meeting at which all shares entitled to
vote thereon were present and voted. As discussed earlier, Collective's
Restated Certificate of Incorporation prohibits stockholder action by written
consent in lieu of a meeting.
 
  Removal of Directors. Under New Jersey corporation law, one or more of all
directors of a corporation may be removed for cause or, unless otherwise
provided in the certificate of incorporation, without cause by shareholders by
the affirmative vote of the majority of the votes cast by the holders of
shares entitled to vote thereon. Unless otherwise provided in the certificate
of incorporation, shareholders of a corporation whose board of directors is
classified may not remove a director except for cause. Under Delaware
corporation law, any director or the entire board of directors may be removed,
with or without cause, by the holders of a majority of the shares then
entitled to vote at an election of directors, except (i) unless the
certificate of incorporation otherwise provides, in the case of a corporation
whose board is classified, stockholders may effect such removal only for
cause; or (ii) in the case of a corporation having cumulative voting, if less
than the entire board is to be removed, no director may be removed without
cause if the votes cast against his removal would be sufficient to elect him
if then cumulatively voted at an election of the entire board of directors,
or, if there be classes of directors, at an election of the class of directors
of which he is a part.
 
  Special Meetings of Shareholders. Under New Jersey corporation law, special
meetings of shareholders may be called by the President or Board of Directors
of the corporation, or by such other officers, directors or shareholders as
provided for in the by-laws. In addition, holders of not less than 10% of a
corporation's voting stock may apply to the New Jersey Superior Court for an
order directing a special meeting of shareholders to be held. Under Delaware
corporation law, special meetings of stockholders may be called by the Board
of Directors or by such person or persons as may be authorized by a company's
certificate of incorporation or the by-laws.
 
  De Facto Merger. Under New Jersey corporation law, shareholders have the
same voting and dissent and appraisal rights as if they were shareholders of a
surviving corporation in a merger, if (1) voting shares outstanding or
issuable after the transaction exceed by more than 40% voting shares
outstanding before the transaction or (2) shares entitled to participate
without limitation in distributions outstanding or issuable after the
transaction exceed by more than 40% such shares outstanding before the
transaction. Delaware corporation law does not contain a comparable provision.
 
  Shareholders' Derivative Actions. New Jersey corporation law contains
certain provisions that have the effect of discouraging derivative actions.
Specifically, New Jersey law authorizes the court having jurisdiction over the
action to award reasonable expenses and attorney's fees to the successful
defendants in a derivative action upon a finding that the action was brought
without reasonable cause. In addition, the corporation may require the
plaintiff or plaintiffs to give security for the reasonable expenses,
including attorneys' fees, that may be incurred by the corporation or by other
named defendants for which the corporation may become legally liable if
plaintiff or plaintiffs are holders of less than 5% of the outstanding shares
of any class or series of such corporation (or voting trust certificates
therefor) unless the shares or trust certificates so held have a market value
in excess of $25,000. Delaware corporation law does not contain comparable
provision.
   
  Proxies. Under New Jersey corporation law, a proxy is valid for no longer
than eleven months unless a longer period is specified. In addition, a proxy
is revocable at will unless coupled with an interest. The death or incapacity
of a shareholder does not revoke a proxy and it will continue in force until
revocation by the shareholder's personal representative. Under Delaware
corporation law, a proxy is not valid beyond three years from its date unless
it so provides for a longer period. In addition, for a proxy to be irrevocable
it must state that it is irrevocable and be coupled with an interest in the
stock itself or in the corporation generally, sufficient in law to support an
irrevocable power.     
 
  Inspection of Books and Records. Under New Jersey corporation law, a
shareholder of record for at least 6 months immediately preceding his demand
or any holder (or a person authorized on behalf of such holder) of
 
                                      49
<PAGE>
 
   
at least 5% of the outstanding shares of any class or series shall have the
right to examine for any proper purpose the minutes of the proceedings of
shareholders and record of shareholders. Further, upon establishing a proper
purpose and receiving a court order a shareholder may examine the books and
records of account, minutes and records of shareholders of a corporation.
Under Delaware corporation law, any stockholder upon written demand under oath
stating the purpose thereof has the right during usual business hours to
inspect for any proper purpose the stock ledger, list of stockholders and
other books and records, and to make copies or abstracts therefrom.     
   
  Anti-takeover Statutes. New Jersey has adopted a type of anti-takeover
statute known as a "business combination" statute. Subject to numerous
qualifications and exceptions, the statute prohibits an interested stockholder
of a corporation from effecting a business combination with the corporation
for a period of five years unless the corporation's board approved the
transaction prior to the stockholder becoming an interested stockholder, the
transaction receives the approval of two-thirds of the voting stock of the
corporation not beneficially owned by the interested stockholder, or the
transaction meets certain minimum financial terms. An "interested stockholder"
is defined to include any beneficial owner of 10% or more of the voting power
of the outstanding voting stock of the corporation and any affiliate or
associate of the corporation who within the prior five-year period has at any
time owned 10% or more of the voting power. The term "business combination" is
defined broadly to include, inter alia, (1) the merger or consolidation of the
corporation with the interested stockholder or any corporation that after such
merger or consolidation would be an affiliate or associate of the interested
stockholder, (2) the sale, lease, exchange, mortgage, pledge, transfer or
other disposition to an interested stockholder or any affiliate or associate
of the interested stockholder of 10% or more of the corporation's assets or
(3) the issuance or transfer to an interested stockholder or any affiliate or
associate of the interested stockholder of 5% or more of the aggregate market
value of the stock of the corporation. The effect of the statute is to protect
non-tendering post-acquisition minority shareholders from mergers in which
they will be "frozen out" after the merger, by prohibiting transactions in
which an acquiror could favor itself at the expense of minority stockholders.
The New Jersey statute does not apply to New Jersey corporations that do not
have either their principal executive offices or significant business
operations located in New Jersey. Delaware has adopted a business combination
type of anti-takeover statute that operates in a manner similar to the New
Jersey statute. Although there are numerous differences between the Delaware
statute and the New Jersey statute, the most significant include the
following: (i) under the Delaware statute, the moratorium imposed on a
business combination with an interested stockholder is three years, as opposed
to five years under the New Jersey statute; (ii) the Delaware statute defines
"interested stockholder" using a 15% ownership threshold rather than the 10%
threshold under the New Jersey statute; (iii) the Delaware statute permits an
interested stockholder to avoid the moratorium by acquiring 85% of the
corporation's voting power in the same transaction in which that stockholder
becomes an interested stockholder (the New Jersey statute does not contain a
comparable provision); and (iv) the Delaware statute applies to Delaware
corporations regardless of the locations of their offices and business
operations.     
   
  Under New Jersey corporation law, a director of a New Jersey corporation, in
discharging his or her duties to the corporation and in determining what he or
she reasonably believes to be in the best interest of the corporation, may, in
addition to considering the effects of any action on shareholders, consider
any of the following: (a) the effects of the action on the corporation's
employees, suppliers, creditors and customers; (b) the effects of the action
on the community in which the corporation operates; and (c) the long-term as
well as the short-term interests of the corporation and its shareholders,
including the possibility that these interests may best be served by the
continued independence of the corporation. Determinations resulting in the
rejection of a proposal or offer to acquire the corporation are expressly
covered by this provision of the New Jersey Business Corporation Act. The
Delaware General Corporation Law contains no such "other constituency"
provision.     
 
  Indemnification. Under New Jersey corporation law, a corporation may
indemnify any person who is or was a director, officer, employee or agent of
the corporation, or is or was serving at the request of the corporation as a
director, officer, trustee, employee or agent of another corporation,
partnership, joint venture, sole proprietorship, trust or other enterprise,
against his reasonable expenses (including counsel fees) in connection with
any pending, threatened or completed proceeding by or in the right of the
corporation to procure a judgment
 
                                      50
<PAGE>
 
   
in its favor which involves such person by reason of his corporate agent
status, if he or she acted in good faith and in a manner he or she reasonably
believed to be in or not opposed to the best interests of the corporation.
However, no indemnification shall be made in respect of any claim, issue or
matter as to which such person shall have been adjudged to be liable to the
corporation, unless, and only to the extent that the Superior Court of New
Jersey or the court in which such proceeding was brought shall determine that,
despite the adjudication of liability but in view of all the circumstances of
the case, such person is fairly and reasonably entitled to indemnity for such
expenses that the Superior Court of New Jersey or such other court shall deem
proper. In connection with any other proceeding, a corporation may indemnify
any such person against his reasonable expenses and liabilities in connection
with any such proceeding if he or she acted in good faith and in a manner he
or she reasonably believed to be in or not opposed to the best interests of
the corporation, and, with respect to any criminal proceeding, he or she had
no reasonable cause to believe his or her conduct was unlawful. New Jersey
corporation law requires that a corporation shall indemnify any such person
against expenses to the extent such person has been successful on the merits
or otherwise in any of the foregoing proceedings or in the defense of any
claim, issue or matter therein, and provides that any such person may apply to
a court for an award of indemnification by the corporation if the corporation
has failed or refused to provide indemnification as provided under the
statute.     
   
  New Jersey corporation law also permits a corporation to purchase and
maintain insurance on behalf of any such person against any expenses incurred
in any proceeding and any liabilities asserted against such person by reason
of his or her corporate agent status, whether or not the corporation would
have the power to indemnify such person under the statute.     
   
  Similarly, the Delaware corporation law provides that a corporation may
indemnify any person with respect to certain pending, threatened or completed
actions (including a suit by or in the right of the corporation to procure a
judgment in its favor) by reason of the fact that he or she is or was a
director, officer, employee or agent of the corporation, or is or was serving
at the request of the corporation as a director, officer, employee or agent of
another corporation, partnership, joint venture, trust or other enterprise
against expenses (including attorneys' fees), judgments, fines and amounts
paid in settlement actually and reasonably incurred by him or her in
connection with the defense or settlement of such action, suit or proceeding
if he or she acted in good faith and in a manner he or she reasonably believed
to be in or not opposed to the best interests of the corporation and, with
respect to any criminal action or proceeding, had no reasonable cause to
believe his or her conduct was unlawful. With respect to derivative actions,
however, no indemnification shall be made in respect of any claim, issue or
matter as to which such person shall have been adjudged to be liable to the
corporation unless and only to the extent that the Court of Chancery of
Delaware or the court in which such action or suit was brought shall determine
upon adjudication that, despite the adjudication of liability but in view of
all the circumstances of the case, such person is fairly and reasonably
entitled to indemnity for such expenses which the Court of Chancery of
Delaware or such other court shall deem proper. Delaware corporation law
requires that a corporation shall indemnify any such person against expenses
to the extent such person has been successful on the merits or otherwise in
any of the foregoing proceedings or defense of any such claims.     
 
  The Delaware corporation law permits a Delaware business corporation to
purchase and maintain insurance on behalf of any person who is or was a
director, officer, employee or agent of the corporation, or is or was serving
at the request of the corporation as a director, officer, employee or agent of
another corporation, partnership, joint venture, trust or other enterprise
against any liability asserted against such person and incurred by him or her
in any such capacity, or arising out of his status as such, whether or not the
corporation would have the power to indemnify such person.
 
  Limitation of Director and Officer Liability. New Jersey corporation law
provides that directors and members of any committee designated by the board
of directors are not liable to a corporation or its shareholders if, acting in
good faith, in discharging their duties they rely upon (i) the opinion of
counsel for the corporation, (ii) written reports setting forth financial data
concerning the corporation and prepared by an independent public accountant or
certified public accountant or firm of such accountants, (iii) financial
statements, books of account or reports of the corporation represented to them
to be correct by the president, the officer of the corporation having charge
of its books of account, or the person presiding at a meeting of the board, or
(iv) written reports
 
                                      51
<PAGE>
 
of committees of the board. The Delaware corporation law contains a similar
provision which states that members of a board of directors or any committee
designated by the board of directors are fully protected in the performance of
their duties if they rely in good faith upon the records of the corporation
and upon such information, opinions, reports or statements presented to the
corporation by any of the corporation's officers or employees, or committees
of the board of directors, or by any other person as to matters the member
reasonably believes are within such other person's professional or expert
competence and who has been selected with reasonable care by or on behalf of
the corporation.
 
  The New Jersey corporation law further provides that the certificate or
incorporation of domestic corporations may contain provisions which limit the
personal liability of directors and officers, in whole or in part, to the
corporation or its shareholders for damages for breach of any duty owed to the
corporation or its shareholders except for acts or omissions (i) in breach of
the director's or officer's duty of loyalty to the corporation or its
shareholders, (ii) not in good faith or involving a knowing violation of law
or (iii) resulting in receipt by such person of an improper personal benefit.
The New Jersey corporation law provides that the duty of loyalty is breached
by an act or omission known or believed by a director or officer to be
contrary to the best interests of the corporation or its shareholders in
connection with matters in which the director or officer has a material
conflict of interest. The Delaware corporation law contains a substantially
similar provision but is restricted in scope to directors only, does not
specifically define what constitutes a breach of the duty of loyalty and
specifically prohibits provisions which eliminate director liability for
unlawful payments of dividends and unlawful stock purchases and redemptions.

                                SUMMIT BANCORP.
 
DESCRIPTION OF BUSINESS
 
  Summit commenced operations on October 1, 1970 as a bank holding company
registered under the BHC Act. Summit owns three bank subsidiaries and eight
active non-bank subsidiaries. At March 31, 1997, Summit had total consolidated
assets of $23.4 billion on the basis of which it ranked as the largest New
Jersey-based bank holding company.
 
  The bank subsidiaries engage in a general banking business. Summit Bank
(Hackensack, NJ) is Summit's largest bank subsidiary, accounting for
approximately 85% of Summit's total consolidated assets at March 31, 1997.
Summit's non-bank subsidiaries engage primarily in discount brokerage,
commercial finance lending, lease financing, and reinsuring credit life and
disability insurance policies related to consumer loans made by the bank
subsidiaries.
   
  The bank subsidiaries operated 385 banking offices located in major trade
centers and suburban areas in New Jersey and Pennsylvania as of March 31,
1997. The following table lists, as of March 31, 1997, each bank subsidiary,
the location in New Jersey or Pennsylvania of its principal office, the number
of its banking offices and, in thousands of dollars, its total assets and
deposits. Both the New Jersey and Pennsylvania subsidiaries are state banks;
however, only the New Jersey banks are members of the Federal Reserve System.

  Summit is a legal entity separate and distinct from its subsidiaries. There
are various legal limitations on the extent to which a bank subsidiary may
finance or otherwise supply funds to Summit or its non-bank subsidiaries.
Under federal law, no bank subsidiary may, subject to certain limited
exceptions, make loans or extensions of credit to, or investments in the
securities of Summit or its non-bank subsidiaries or take their securities as
collateral for loans to any borrower. Each bank subsidiary is also subject to
collateral security requirements for any loans or extensions of credit
permitted by such exceptions. In addition, certain bank regulatory limitations
exist on the availability of subsidiary bank undistributed net assets for the
payment of dividends to Summit without the prior approval of the bank
regulatory authorities. The Federal Reserve Act, which affects Summit's state
member banks, restricts the payment of dividends in any calendar year to the
net profit of the current year combined with retained net profits of the
preceding two years. Each bank, as a state-chartered bank, may declare a
dividend only if, after payment thereof, its capital would be unimpaired and
its remaining surplus would equal 50 percent of its capital (New Jersey) or
100 percent of its capital (Pennsylvania). In addition, under the Federal
Deposit Insurance Corporation Improvement Act of 1991, all institutions are
prohibited from paying dividends if after doing so an institution would be
"undercapitalized". At March 31, 1997, the total undistributed net assets of
Summit's subsidiary banks were $1.8 billion of which $194.6 million was
available under the most restrictive limitations for the payment of dividends
to Summit.

                      DESCRIPTION OF SUMMIT CAPITAL STOCK
 
  Summit is presently authorized to issue 260,000,000 shares of Summit Common
and 4,000,000 shares of Preferred Stock, without par value ("Summit
Preferred"). As of March 31, 1997, there were 98,450,950 shares of Summit
Common outstanding, no shares of Summit Preferred outstanding and 1,000,000
shares (subsequently increased to 1,500,000 shares) of Summit Series R
Preferred designated in Summit's Restated Certificate of Incorporation and
reserved for issuance under the Summit Rights Plan (as defined herein).
Pursuant to the New Jersey Business Corporation Act, the Summit Board has
authority to set the terms and conditions of the authorized but unissued
Summit Preferred. Summit may issue any authorized Summit Common and Summit
Preferred without further stockholder vote, unless such a vote is required for
a particular transaction by applicable law or stock exchange rules, including
rules of the NYSE, on which the Summit Common is presently listed. The
issuance of additional Summit Common or Summit Preferred, including Summit
Preferred that might be convertible into Summit Common, may, among other
things, affect the earnings per share applicable to existing Summit Common and
the equity and voting rights of existing holders of Summit Common.
 
  The following summary does not purport to be complete and is subject in all
respects to the applicable provisions of the New Jersey Business Corporation
Act, Summit's Restated Certificate of Incorporation and Summit's Rights Plan.
 
COMMON STOCK
 
  The rights of holders of Summit Common are subject to the preferences as to
dividends and liquidation rights and other prior rights, if any, of any class
or series of Summit Preferred that may be issued. The holders of Summit Common
are entitled to one vote for each share with respect to all matters voted upon
by shareholders, including the election of directors, and are entitled to
receive dividends when, as and if declared by the Summit Board out of funds of
Summit legally available therefor. Shares of Summit Common do not have
cumulative voting rights; accordingly, at any annual meeting of Summit
shareholders (or at any special meeting of shareholders where an election of
directors is conducted) the holders of 50 percent plus 1 of the shares
represented at the meeting (provided a quorum is present) can fill all
positions on the Summit Board that are up for election at such meeting if they
so choose and, in such event, the holders of the remaining shares will not be
able to fill any of such positions. Summit has a classified Board of
Directors, under which approximately one-third of the directors are elected
each year. In the event of the liquidation of Summit, holders of Summit Common
are entitled to share pro rata in the distribution of Summit's assets
available for such purpose. All shares of Summit Common are fully paid and
nonassessable. No preemptive rights attach to the ownership of Summit Common
and no personal liability is imposed on the holders thereof by reason of the
ownership of such shares. First Chicago Trust Company of New York is the
transfer agent, dividend disbursing agent and registrar for the Summit Common.
Summit Bank (Hackensack, NJ) is the co-transfer agent.
 
TRUST PREFERRED SECURITIES
          
  On March 20, 1997, Summit Capital Trust I ("Trust"), a statutory business
trust created under the laws of the State of Delaware and wholly-owned
subsidiary of Summit, issued $150.0 million of 8.4% Capital Trust Pass-through
Securities, representing undivided beneficial interests in the assets of the
Trust ("Capital Securities"), and $4.6 million of Common Securities,
representing undivided beneficial interests in the assets of the Trust
("Common Securities") (collectively, the Capital Securities and Common
Securities are referred to as the "Trust Securities"). The Trust used the
proceeds received from the sale of the Trust Securities to purchase $154.6
million of 8.4% Junior Subordinated Deferrable Interest Debentures due 2027
issued by Summit ("Subordinated Debentures"). The Trust was created solely for
the purpose of investing the proceeds received from the sale of the Trust
Securities in the Subordinated Debentures. Summit has guaranteed that, to the
extent the Trust has received certain payments from Summit, the Trust will
distribute such funds.     
 
SHAREHOLDER RIGHTS PLAN
 
  In August 1989, Summit adopted a shareholder rights plan ("Rights Plan"),
under which preferred stock purchase rights ("Rights") attached to Summit
Common outstanding as of the close of business on August 28,
 
                                      54
<PAGE>
 
1989. Holders of shares of Summit Common issued subsequent to that date
receive the Rights with their shares. Except as indicated below, each Right
entitles the registered holder to purchase from Summit one-hundredth of a
share of a new series of Summit Preferred Stock, designated the Series R
Preferred Stock ("Summit Series R Preferred"). The Rights expire on August 16,
1999, and are subject to redemption and amendment in certain circumstances.
The Rights trade automatically with shares of Summit Common and become
exercisable only under certain circumstances as described below.
 
  In general, the Rights will become exercisable upon the earlier to occur (a
"Distribution Date", as defined in the Rights Plan) of the following: (1) ten
days following a public announcement that a person or group has acquired
beneficial ownership of 15% or more of the Summit Common outstanding at that
time or voting securities of Summit representing 15% or more of the total
voting power of Summit (such person or group becoming an "Acquiring Person",
as defined in the Rights Plan) or (2) ten business days (or such later date as
the Summit Board may determine) after the commencement of a tender offer or
exchange offer that would result in a person or group beneficially owning 30%
or more of the outstanding Summit Common or voting securities representing 30%
or more of the total voting power of Summit.
 
  Generally, in the event a Distribution Date occurs by virtue of a person or
group becoming an Acquiring Person (other than pursuant to an offer for all
outstanding shares of Summit Common and other voting securities that the
Summit Board determines to be fair to shareholders and otherwise in the best
interests of Summit), each Right, other than Rights owned by the Acquiring
Person, will thereafter entitle the holder to receive, upon exercise of the
Right, Summit Series R Preferred having a value equal to two times the
exercise price of the Right.
 
  In the event that a Distribution Date occurs (under either of the
circumstances described above) and Summit is acquired in a merger or other
business combination, or more than 50% of Summit's assets or earning power is
sold or transferred, each Right will thereafter entitle the holder there to
receive, upon the exercise of the Right, common stock of the acquirer having a
value equal to two times the exercise price of the Right.
   
  Summit may redeem the Rights, in whole but not in part, at any time on or
prior to the close of business on the earlier of (1) the tenth day after a
public announcement that a person has become an Acquiring Person or (2) the
close of business on August 16, 1999, at a price of $.01 per Right (the
"Redemption Price"), but only by the vote of a majority of the Independent
Directors (as defined in the Rights Plan). Summit may also redeem the Rights
following the tenth day after a public announcement that a person has become
an Acquiring Person, in whole but not in part, in connection with the Summit
Board's approval of an agreement providing for a merger or other business
combination not involving an Acquiring Person, but only by the vote of a
majority of the Independent Directors. Immediately upon the action of the
Board of Directors authorizing redemption of the Rights, the right to exercise
the Rights will terminate and the only right of the holders of Rights will be
to receive the Redemption Price.     
 
  The combination of prohibitive dilution of the Acquiring Person's share
values and the power of the Summit Board to redeem the Rights is intended to
encourage potential acquiring persons to negotiate with the Summit Board with
respect to the terms of any acquisition or business combination and, to the
extent possible, discourage or defeat abusive partial or two-tiered
acquisition proposals.
 
  The foregoing description of the Rights Plan does not purport to be complete
and is qualified in its entirety by reference to the terms of the Rights Plan,
which is more fully described in Summit's Registration Statement on Form 8-A
filed August 28, 1989.

                           COLLECTIVE BANCORP, INC.
 
DESCRIPTION OF BUSINESS
 
  Collective was formed in December, 1988, as a Delaware business corporation
and is headquartered in Cologne, New Jersey. Collective conducts its
operations primarily through a federally-insured savings bank subsidiary,
Collective Bank. Collective Bank also owns subsidiaries that are engaged in
securities brokerage, insurance agency and mortgage lending activities.
Collective is registered as a unitary savings and loan holding company with
the Office of Thrift Supervision ("OTS") under the Home Owners' Loan Act, as
amended (the "HOLA") and is subject to OTS regulation, examination,
supervision and reporting requirements. At March 31, 1997, Collective had
total consolidated assets of $5.5 billion.
   
  Collective Bank is principally engaged in the business of attracting
deposits from the general public and using those deposits, together with
borrowings and other funds, to originate loans secured by real estate, to
purchase mortgage-backed securities and, to a lesser extent, to originate
various types of consumer and commercial loans and make other investments,
under the HOLA. In addition, the activities of Collective Bank are governed by
the HOLA and the Federal Deposit Insurance Act. Collective Bank operates 82
banking offices providing depository and lending services to individuals and
businesses throughout New Jersey.     
   
  Collective Bank is subject to extensive regulation, examination and
supervision by the OTS, as its primary federal regulator, and the FDIC, as the
deposit insurer. The Bank is a member of the Federal Home Loan Bank System and
its deposit accounts are insured up to applicable limits by the Savings
Association Insurance Fund managed by the FDIC. This regulation and
supervision establishes a comprehensive framework of activities in which
Collective Bank can engage and is intended primarily for the protection of the
insurance fund and depositors.     
 
                    DESCRIPTION OF COLLECTIVE CAPITAL STOCK
 
COMMON STOCK
 
  Collective is presently authorized to issue 37,000,000 shares of Collective
Common and 2,500,000 shares of Preferred Stock. As of March 31, 1997, there
were 20,446,519 shares of Collective Common outstanding and no shares of
Collective Preferred Stock outstanding.
 
  Dividends and Liquidation Rights. The holders of Collective Common are
entitled to receive and share equally in such dividends as may be declared by
the Collective Board out of funds legally available therefor. In the event of
the liquidation of Collective, holders of Collective Common are entitled to
share pro rata in the distribution of Collective's assets for such purpose.
 
  Voting Rights. The holders of Collective Common elect the Collective Board
and act on such other matters as are required to be presented to them under
the Delaware General Corporation Law, Collective's Restated Certificate of
Incorporation or as are otherwise presented to them by the Collective Board.
Each holder of Collective Common is entitled to one vote per share. Holders of
Collective Common are entitled to cumulate votes in the election of directors.
Collective has a classified Board of Directors under which one-third of the
directors are elected each year. Directors of Collective are elected by a
plurality of votes cast.
 
  Preemptive Rights. Holders of Collective Common are not entitled to
preemptive rights with respect to any shares that may be issued.

              PROPOSAL II--RIGHT TO ADJOURN SPECIAL MEETING     
   
  In the event there are not sufficient votes to constitute a quorum or to
approve the Merger Agreement at the scheduled date and time of the Special
Meeting, the Merger Agreement could not be approved unless the Special Meeting
were postponed or adjourned in order to permit further solicitation of
proxies. In order to allow proxies that have been received by Collective at
the time of the Special Meeting to be voted for such adjournment, if
necessary, Collective has submitted the question of the right to adjourn under
the circumstances to its stockholders as a separate matter for their
consideration. A majority of the shares present in person or represented by
proxy at the Special Meeting and entitled to vote on Proposal II is required
in order to approve any such right to adjourn. The Board of Directors of
Collective recommends that stockholders vote their proxies in favor of such
right so that their proxies may be voted for adjournment of the Special
Meeting in the event it should become necessary. Properly executed proxies
will be voted in favor of any such adjournment right unless otherwise
indicated thereon, except that if no vote is indicated with respect to
Proposal II on a proxy card indicating a vote against the proposal to approve
the Merger Agreement, the proxy will not be voted in favor of Proposal II. If
it is necessary to adjourn the Special Meeting, no notice of the time and
place of the adjourned meeting is required to be given to stockholders other
than an announcement of such time and place at the Special Meeting.     
 
                             STOCKHOLDER PROPOSALS
 
  In order to be eligible for inclusion in Collective's proxy materials for
Collective's Annual Meeting of Stockholders, in the event that the Merger is
not consummated prior to such meeting, any stockholder proposal to take action
at such meeting would have been required to be received at Collective's main
office at 158 Philadelphia Avenue, Egg Harbor City, New Jersey 08215, not
later than May 16, 1997. Any such proposals shall be subject to the
requirements of the proxy rules adopted under the Exchange Act.
   
  The Summit Board will consider and include in the Summit Proxy Statement for
the 1998 Annual Meeting of Summit Shareholders proposals which meet the
regulations of the Commission and New Jersey law and which comply with
Summit's By-Laws. In order to be considered for inclusion, proposals must be
received on or before November 7, 1997. Proposals should be addressed to the
Secretary of Summit.     
   
  The By-Laws of Summit provide that shareholder proposals which do not appear
in the proxy statement may be considered at a meeting of shareholders only if
written notice of the proposal is received by the Secretary of Summit not less
than 80 and not more than 100 days before the anniversary of the preceding
year's annual meeting provided, however, that, if the date of the annual
meeting is more than 30 days before or more than 60 days after such
anniversary date, the notice of a shareholder proposal, to be timely, must be
received by the Secretary not later than the close of business on the later of
the 80th day prior to such annual meeting or the tenth day following the day
on which public announcement of the meeting date is first made. Any such
notice of a shareholder proposal by a shareholder to the Secretary of Summit
must be accompanied by (a) the name and address of the shareholder who intends
to present the proposal for a vote, (b) a representation that such shareholder
is a holder of record of shares entitled to vote at the meeting, (c) a
description of all agreements, arrangements or understandings between such
shareholder and any other shareholder relating to the proposal to be voted on
and any financial contractual interest of such shareholder in the outcome of
such vote and (d) such other information regarding the proposal to be voted on
and the shareholder intending to represent the proposal for a vote as would be
required to be included in a proxy statement soliciting the vote of
shareholders in respect of such proposal pursuant to the proxy rules of the
Commission.

corporation being hereinafter sometimes referred to as the "Surviving
Corporation").

  Section 1.03. Terms of Conversion of Collective Capital Stock.
 
  (a) At the Effective Time, by virtue of the Merger and without any action on
the part of any shareholder of Collective:
 
  (1) All shares of the Common Stock, par value $.01 per share, of Collective
      ("Collective Stock") which immediately prior to the Effective Time are
      owned beneficially by Summit or a subsidiary of Summit (other than
      Collective Stock held as a result of debts previously contracted), if
      any, are held in the treasury of Collective, if any, or owned
      beneficially by Collective or a subsidiary of Collective (other than
      Collective Stock held as a result of debts previously contracted) shall
      be canceled and retired and no cash, securities or other consideration
      shall be payable or paid or delivered under this Agreement in exchange
      for such Collective Stock; and
 
  (2) Subject to Section 1.03(a)(1), outstanding shares of Collective Stock
      held as of the Effective Time by each Collective Shareholder (as
      defined at Section 1.07(c) below) shall be converted in accordance with
      the New Jersey Act and the Delaware Law into the right to receive whole
      shares of the Common Stock, par value $1.20 per share, of Summit
      ("Summit Stock") and cash in lieu of fractional shares of Summit Stock
      as follows: the aggregate number of shares of Collective Stock held by
      each Collective Shareholder shall be multiplied by the Exchange Ratio
      and (i) the number of whole shares of Summit Stock an Collective
      Shareholder shall become entitled to receive pursuant to this Section
      1.03(a)(2) shall equal the whole number resulting from the foregoing
      multiplication, and (ii) the cash in lieu of a fractional share of
      Summit Stock ("Cash In Lieu Amount") an Collective Shareholder shall
      become entitled to receive pursuant to this Section 1.03(a)(2) shall
      equal the product obtained by multiplying the fraction, if any, which
      results from the foregoing multiplication by the closing price of one
      share of Summit Stock on the New York Stock Exchange-Composite
      Transactions List on the last trading day ending prior to the Effective
      Time. (The shares of Summit Stock issuable in accordance with this
      Section 1.03(a)(2) are sometimes referred to herein as the "Shares").
      (The Shares and any Cash In Lieu Amounts payable in the Merger are
      sometimes collectively referred to herein as the "Merger
      Consideration").
 
  (b) In the event that, from the date hereof to the Effective Time, the
outstanding Summit Stock shall have been increased, decreased, changed into or
exchanged for a different number or kind of shares or securities through
reorganization, recapitalization, reclassification, stock dividend, stock
split, reverse stock split or there occur other like changes in the
outstanding shares of Summit Stock, the Exchange Ratio and, if necessary, the
form and amount of Summit capital stock issuable in the Merger in exchange for
Collective Stock shall be appropriately adjusted so that Collective
Shareholders who become entitled to receive Summit Stock pursuant to the
provisions hereof shall be entitled to receive such number of whole shares of
Summit Stock or other stock (and Cash In Lieu Amount, if any) as they would
have received if the Effective Time had occurred prior to the happening of
such event.
 
  (c) The "Exchange Ratio" is hereby defined to be .895.
 
  Section 1.04. Reservation of Summit Stock; Issuance of Shares Pursuant to
the Merger. Summit shall reserve and make available for issuance to holders of
Collective Stock in connection with the Merger, on the terms and subject to
the conditions of this Agreement, sufficient shares of Summit Stock (which
shares, when issued and delivered, will be duly authorized, legally and
validly issued, fully paid and non-assessable and subject to no preemptive
rights). Upon the terms and subject to the conditions of this Agreement,
particularly Sections 1.03 and 1.07, Summit shall issue the Shares upon the
effectiveness of the Merger to Collective Shareholders.
 
  Section 1.05. Exchange Agent Arrangements. Prior to the Effective Time,
Summit shall appoint First Chicago Trust Company of New York, or another
entity reasonably satisfactory to Collective, as the exchange agent ("Exchange
Agent") responsible for exchanging, in connection with and upon consummation
of the Merger and subject to Sections 1.03 and 1.07, certificates representing
whole shares of Summit Stock ("Summit Certificates") and Cash In Lieu Amounts
for certificates representing shares of Collective Stock ("Collective
 
                                      A-2
<PAGE>
 
Certificates") and Summit shall deliver to the Exchange Agent sufficient
Summit Certificates and cash as shall be required to satisfy Summit's
obligations to Collective Shareholders under Section 1.07(c), prior to the
time such obligations arise.
 
  Section 1.06. Effective Time. The Merger shall be effective at the hour and
on the date ("Effective Time") specified in the Certificate of Merger of
Summit and Collective required by this Agreement to be filed with the
Secretary of State of the State of New Jersey in accordance with Section
14A:10-4.1 of the New Jersey Act ("NJ Certificate"), or, if filed later than
the effective hour and date set forth in the NJ Certificate, the date the
Certificate of Merger required by this Agreement to be filed with the
Secretary of State of the State of Delaware ("Delaware Certificate") is filed
in accordance with Section 252 of the Delaware Law. (The NJ Certificate and
the Delaware Certificate are collectively referred to herein as the
"Certificates of Merger"). Summit shall file the Certificates of Merger as
promptly as practicable following the Closing (as defined at Section 9.01) but
in no event later than one business day following the date the Closing shall
occur.
 
  Section 1.07. Exchange of Collective Certificates.
 
  (a) After the Effective Time and subject to Section 1.07(c) below, each
Collective Shareholder (except as provided otherwise in Section 1.03(a)(1)
above), upon surrender to the Exchange Agent of all Collective Certificates
registered to the Collective Shareholder, shall be entitled to receive in
exchange therefor a Summit Certificate representing the number of whole shares
of Summit Stock such Collective Shareholder becomes entitled to receive
pursuant to Section 1.03(a)(2) and the Cash In Lieu Amount, payable by check,
such Collective Shareholder may become entitled to receive pursuant to Section
1.03(a)(2). Until so surrendered, outstanding Collective Certificates held by
each Collective Shareholder, other than certificates for Collective Stock
governed by Section 1.03(a)(1), shall be deemed for all purposes (other than
as provided below with respect to unsurrendered Collective Certificates and
Summit's right to refuse payment of dividends or other distributions, if any,
in respect of Summit Stock) to represent only the right to receive the number
of whole shares of Summit Stock and the Cash In Lieu Amount, if any,
determined in accordance with Section 1.03(a)(2). Until so surrendered, Summit
may, at its option, refuse to pay to the holders of the unsurrendered
Collective Certificates dividends or other distributions, if any, payable to
holders of Summit Stock; provided, however, that upon the surrender and
exchange of Collective Certificates following a dividend or other distribution
by Summit there shall be paid to such Collective Shareholders the amount,
without interest, of dividends and other distributions, if any, which became
payable prior thereto but which were not paid.
 
  (b) Holders of Collective Certificates as of the Effective Time shall cease
to be, and shall have no further rights as, shareholders of Collective.
 
  (c) As promptly as practicable, but in no event more than 7 days, after the
Exchange Agent receives an accurate and complete list of all holders of record
of outstanding Collective Stock as of the Effective Time ("Collective
Shareholders") (including the address and social security number of and the
number of shares of Collective Stock held by each Collective Shareholder) from
Collective ("Final Shareholder List"), Summit shall cause the Exchange Agent
to send to each Collective Shareholder instructions and transmittal materials
for use in surrendering and exchanging Collective Certificates for the Merger
Consideration. If Collective Certificates are properly presented to the
Exchange Agent (with proper presentation including satisfaction of all
requirements of the letter of transmittal), Summit shall as soon as
practicable, but in no event more than 7 days, after the later to occur of
such presentment or the receipt by the Exchange Agent of an accurate and
complete Final Shareholder List from Collective cause the Exchange Agent to
cancel and exchange Collective Certificates for Summit Certificates and Cash
In Lieu Amounts, if any; provided, however, that if the Exchange Agent, in
order to satisfy its obligations under the Code with respect to the reporting
of dividend income to former shareholders of Collective, must suspend the
exchange process provided for in the second sentence of this Section 1.07(c)
in order to preserve and report the required reporting information, the 7-day
exchange requirement shall be extended 5 business days for exchanges being
processed by the Exchange Agent at the commencement of, or which are received
during, the period of the suspension.
 
 
                                      A-3

  (d) At and after the Effective Time there shall be no transfers on the stock
transfer books of Collective of the shares of Collective Stock which were
outstanding immediately prior to the Effective Time.
 
  Section 1.08. Restated Certificate of Incorporation and By-Laws. The
Restated Certificate of Incorporation of Summit in effect immediately prior to
the Effective Time shall be the Restated Certificate of Incorporation of the
Surviving Corporation, except as duly amended thereafter and except to the
extent such is deemed by law to be affected by the Certificate of Merger. The
By-Laws of Summit in effect immediately prior to the Effective Time shall be
the By-Laws of the Surviving Corporation, except as duly amended thereafter.
 
  Section 1.09. Board of Directors and Officers. The Board of Directors of the
Surviving Corporation shall consist of (i) the members of the Board of
Directors of Summit at the Effective Time, (ii) Thomas H. Hamilton, Chairman
and Chief Executive Officer of Collective, provided he is still serving as
such at the Effective Time and is available for service, who, subject to the
foregoing proviso, shall be designated to serve as a member of that class of
Summit directors with a term of office expiring at the 2000 Annual Meeting of
the Shareholders of Summit, and (iii) one other person chosen by the Board of
Directors of Summit from among those persons serving as Collective directors
on the date hereof and who continue to serve as Collective directors through
the Effective Time, who shall be designated to serve as a member of that class
of Summit directors with a term of office expiring at the 1999 Annual Meeting
of the Shareholders of Summit,. The officers of the Surviving Corporation
shall consist of the officers of Summit at the Effective Time. Such directors
and officers shall serve as such for the terms prescribed in the Restated
Certificate of Incorporation and By-Laws of Summit, or otherwise as provided
by law or until their earlier deaths, resignation or removal.
 
  Section 1.10. Collective Stock Options.
 
  (a) At the Effective Time, each Collective Option (as defined in Section
1.10(b) below) shall be deemed to constitute, and shall automatically be
converted in accordance with the Exchange Ratio into, options to purchase
Summit Stock ("Summit Options") and each Summit Option shall be administered
in accordance with the terms and conditions provided for in the Collective
Option Plan under which the corresponding Collective Option was granted and
the stock option agreement by which it was evidenced, including terms and
provisions regarding exercisability. The number of shares of Summit Stock
which may be purchased upon exercise of a particular Summit Option shall be
the number of shares of Summit Stock which would have been issued in the
Merger if the shares of Collective Stock purchasable upon exercise of the
corresponding Collective Option were issued and outstanding immediately prior
to the Effective Time; provided, however, that the number of shares of Summit
Stock that may be purchased upon exercise of a Summit Option shall not include
any fractional share interest but shall be rounded down to the next lower full
share. The exercise price per share of Summit Stock purchasable upon exercise
of a Summit Option shall equal the exercise price per share of Collective
Stock as set forth in the corresponding Collective Option so converted divided
by the Exchange Ratio (subject to any adjustments provided for in this
Agreement), rounded to the fourth decimal place. Within 30 days after the
receipt by Summit of an accurate and complete list of all holders of
Collective Options (including the address and social security number of each
such holder and a description of the Collective Options held by such holder
specifying, at a minimum, the plan under which issued, type (incentive or
nonqualified), grant date, expiration date, exercise price and the number of
shares of Collective Stock subject thereto) ("Final Option List"), Summit
shall issue to the holders of such Collective Options appropriate instruments
confirming the rights of such holders with respect to Summit Stock, on the
terms and conditions provided by this Section 1.10, upon surrender of the
outstanding instruments representing such Collective Options; provided,
however, that Summit shall not be obligated to issue any such confirming
instruments which relate to the issuance of Summit Stock, or issue any shares
of Summit Stock, until such time as the shares of Summit Stock issuable upon
exercise of Summit Options shall have been registered with the Securities and
Exchange Commission (the "SEC") pursuant to an effective registration
statement and authorized for listing on the New York Stock Exchange and for
sale by any appropriate state securities regulators, which Summit shall use
its best efforts to effect within 30 days after Collective shall have
delivered to Summit the Final Option List. Summit shall use its best efforts
to maintain the effectiveness of such registration statement (and maintain the
current status of the prospectus or prospectuses contained therein) for so
long as the Summit Options remain outstanding. At or prior to the Effective
Time, Summit shall take all
 
                                      A-4
<PAGE>
 
corporate action necessary to reserve for issuance a sufficient number of
shares of Summit Stock for delivery upon exercise of Summit Options.
 
  (b) For purposes of this Section 1.10, "Collective Option" is hereby defined
to mean a stock option for Collective Stock outstanding on the date hereof and
all rights appertinent thereto granted under the Collective Federal Savings
and Loan Association Stock Option Plan or the Collective Incentive Stock
Option Plan ("Collective Option Plans") and not subsequently exercised,
terminated, forfeited or expired prior to the Effective Time.
 
  Section 1.11. Additional Actions. If, at any time after the Effective Time,
the Surviving Corporation shall consider or be advised that any deeds, bills
of sale, assignments, assurances or any other actions or things are necessary
or desirable to vest, perfect or confirm of record or otherwise in the
Surviving Corporation its right, title or interest in, to or under any of the
rights, properties or assets of Collective acquired or to be acquired by the
Surviving Corporation as a result of, or in connection with, the Merger or
otherwise to carry out this Agreement, the officers and directors of the
Surviving Corporation shall be authorized to execute and deliver, in the name
and on behalf of Collective or otherwise, all such deeds, bills of sale,
assignments and assurances and to take, in the name and on behalf of
Collective, all such other actions and things as may be necessary or desirable
to vest, perfect or confirm any and all right, title and interest in, to and
under such rights, properties or assets in the Surviving Corporation or
otherwise to carry out this Agreement.
 
  Section 1.12. Unclaimed Merger Consideration. If, upon the expiration of one
year following the Effective Time, Merger Consideration remains with the
Exchange Agent due to the failure of Collective Shareholders to surrender and
exchange Collective Certificates for Merger Consideration, Summit may, at its
election, continue to retain the Exchange Agent for purposes of the surrender
and exchange of Collective Certificates or take possession of such unclaimed
Merger Consideration, in which such latter case, Collective Shareholders who
have theretofore failed to surrender and exchange Collective Certificates
shall thereafter look only to Summit for payment of the Merger Consideration
and the unpaid dividends and distributions on the Summit Stock constituting
some or all of the Merger Consideration, without any interest thereon.
Notwithstanding the foregoing, none of Summit, Collective, the Exchange Agent
or any other person shall be liable to any former holder of shares of
Collective Stock for any property properly delivered to a public official
pursuant to applicable abandoned property, escheat or similar laws.
 
  Section 1.13. Lost Collective Certificates. In the event any Collective
Certificate shall have been lost, stolen or destroyed, upon the making of an
affidavit of that fact by the person claiming such Collective Certificate to
be lost, stolen or destroyed and the posting by such person of a bond in such
amount as Summit may determine is reasonably necessary as indemnity against
any claim that may be made against it with respect to such Collective
Certificate, the Exchange Agent will issue in exchange for such lost, stolen
or destroyed Collective Certificate the Merger Consideration deliverable in
respect thereof pursuant to this Agreement.
 
                                  ARTICLE II.

more of the shares or other interests having by their terms ordinary voting
power to elect a majority of the Board of Directors or other group performing

<PAGE>
 
organized, validly existing and in good standing under the laws of the state
of its incorporation, qualified to transact business under the laws of all
jurisdictions where the failure to be so qualified would be likely to have a
material adverse effect on (i) the business, results of operations, assets or
financial condition of Collective and its subsidiaries on a consolidated
basis, or (ii) the ability of Collective to perform its obligations under, and
to consummate the transactions contemplated by, this Agreement ("Collective
Material Adverse Effect" or "Collective Material Adverse Change"). However, an
Collective Material Adverse Effect or Collective Material Adverse Change will
not include a change resulting from a change in law, rule, regulation,
generally accepted or regulatory accounting principle or other matter
affecting banking institutions or their holding companies generally or from
charges or expenses incident to the Merger. Each of Collective and its nonbank
subsidiaries has all corporate power and authority and all material licenses,
franchises, certificates, permits and other governmental authorizations which
are legally required to own and lease its properties and assets, to occupy its
premises and to engage in its business and activities as presently engaged in,

nonbank subsidiaries have been fully paid, were duly authorized and validly
issued, are non-assessable and have been issued pursuant to an effective
registration statement under the Securities Act of 1933, as amended (the
"Securities Act") or an appropriate exemption from registration under the
Securities Act and were not issued in violation of the preemptive rights of
any shareholder. Except as set forth in this Section 2.01(d), except for

any nonbank subsidiary of Collective outstanding, in existence, the subject of
an agreement or reserved for issuance.
 
  (2) "Equity Securities" of an issuer means (i) the capital stock or other
equity securities of such issuer, options, warrants, scrip, interests in,

equity security of such issuer.
 
  (3) No Collective plan or contract, whether oral or written or formal or
informal, exists which provides for the granting or awarding of Collective
Stock, stock options, stock appreciation rights or other securities,
derivative securities or stock-based cash rights to any person other than the
Collective Option Plans, the Collective Bancorp, Inc. Restricted Stock Plan
("Collective Employee Restricted Stock Plan") and the Collective Bancorp, Inc.
1993 Non-Employee Directors' and Qualified Consultant's Restricted Stock Award
Plan ("Collective Director Restricted Stock Plan") and the contracts issued
pursuant thereto. (The Collective Employee Restricted Stock Plan and the
Collective Director Restricted Stock Plan are sometimes collectively referred
to herein as the "Collective Restricted Stock Plans", and the Collective
Restricted Stock Plans and

"Collective Stock Plans"). The Collective Stock Plans, including all
amendments thereto, have been duly approved by the shareholders of Collective
in compliance with any applicable laws or applicable regulations of
governmental or self-regulatory authorities. Copies of the Collective Stock
Plans, including all amendments thereto, have been previously provided to
Summit. All information relating to outstanding grants and awards under the

nonqualified or incentive; if a right, type and whether or not granted in
tandem with an option), exercise price, number of shares, performance goals),
is set forth in Collective Schedule 2.01(d).
 
  (e) Collective owns no bank subsidiary other than the Collective Bank
("Bank") ("bank" is hereby defined to include commercial banks, savings banks,
private banks, trust companies, savings and loan associations, building and
loan associations and similar institutions receiving deposits and making
loans). Bank is a bank duly organized, validly existing, and in good standing
under the jurisdiction of its organization and is qualified to transact
business under the laws of all jurisdictions where the failure to be so
qualified would be likely to have an Collective Material Adverse Effect. Bank
is duly authorized to conduct all activities and exercise all powers of a
Federal savings bank as contemplated by the applicable Federal laws of the
United States. Bank is an insured bank as defined in the Federal Deposit
Insurance Act, and has all corporate power and authority and all material
licenses, franchises, certificates, permits and other governmental
authorizations which are legally required to own and lease its properties and
assets, to occupy its premises, and to engage in its business and activities
as presently engaged in, and has complied in all material respects with all
applicable laws, regulations and orders.
 
  (f) The authorized and outstanding capital stock of Bank is as set forth on
Collective Schedule 2.01(f). Collective is the holder and beneficial owner of
all of the issued and outstanding Equity Securities of Bank. All issued and
outstanding shares of the capital stock of Bank have been fully paid, were
duly authorized and validly issued, are non-assessable, and were not issued in
violation of the preemptive rights of any shareholder. All Equity Securities
of Bank outstanding, in existence, the subject of an agreement or reserved for
issuance are described in all material respects on Collective Schedule
2.01(f).
 
  (g) All Equity Securities of its direct and indirect subsidiaries
beneficially owned by Collective or a subsidiary of Collective are held free
and clear of any claims, liens, encumbrances or security interests.
 
  Section 2.02. Financial Statements. The financial statements and schedules
contained or incorporated in (a) Collective's annual report to shareholders
for the fiscal year ended June 30, 1996, (b) Collective's annual report on
Form 10-K filed pursuant to the Securities Exchange Act of 1934, as amended
("Exchange Act") for the fiscal year ended June 30, 1996 and (c) Collective's
quarterly reports on Form 10-Q filed pursuant to the Exchange Act for the
fiscal quarters ended September 30, 1996 and December 31, 1996 (the
"Collective Financial Statements") are true and correct in all material
respects as of their respective dates and each fairly presents (subject, in
the case of unaudited statements, to recurring audit adjustments normal in
nature and amount), in accordance with generally accepted accounting
principles, the consolidated statements of condition, income, changes in
stockholders' equity and cash flows of Collective and its subsidiaries at its
respective date and for the period to which it relates, except as may
otherwise be described therein. The Collective Financial Statements do not, as
of the dates thereof, include any material asset or omit any material
liability, absolute or contingent, or other fact, the inclusion or omission of
which renders the Collective Financial Statements, in light of the
circumstances under which they were made, misleading in any respect.
 
  Section 2.03. No Conflicts. Collective and each of its subsidiaries is not
in, and has received no notice of, violation or breach of, or default under,
nor will the execution, delivery and performance of this Agreement by
Collective, or the consummation of the transactions contemplated hereby
including the Merger by Collective upon the terms provided herein (assuming
receipt of the Required Consents, as that term is defined in Section 4.01),
violate, conflict with, result in the breach of, constitute a default under,
give rise to a claim or right of

termination, cancellation, revocation of, or acceleration under, or result in
the creation or imposition of any lien, charge or encumbrance upon any of the
material rights, permits, licenses, assets or properties of Collective or any
of its subsidiaries or upon any of the Equity Securities of Collective or any
of its subsidiaries, or constitute an event which could, with the lapse of
time, action or inaction by Collective or any of its subsidiaries or a third
party, or the giving of notice and failure to cure, result in any of the
foregoing, under any of the terms, conditions or provisions, as the case may
be, of:
 
    (a) the Restated Certificate of Incorporation or the By-Laws of
  Collective or any of its subsidiaries;
 
    (b) any applicable law, statute, rule, ruling, determination, ordinance
  or regulation of or agreement with any governmental or regulatory
  authority;
 
    (c) any judgment, order, writ, award, injunction or decree of any court
  or other governmental authority; or
 
    (d) any material note, bond, mortgage, indenture, lease, policy of
  insurance or indemnity, license, contract, agreement or other instrument;
 
to which Collective or any of its subsidiaries is a party or by which
Collective or any of its subsidiaries or any of their assets or properties are
bound or committed, the consequences of which individually or in the aggregate
would be likely to result in a Collective Material Adverse Change, or enable
any person to enjoin the transactions contemplated hereby.
 
  Section 2.04. Absence of Undisclosed Liabilities. Except as disclosed in
Collective Schedule 2.04, Collective and its subsidiaries have no liabilities,
whether contingent or absolute, direct or indirect, matured or unmatured
(including but not limited to liabilities for federal, state and local taxes,
penalties, assessments, lawsuits or claims against Collective or any of its
subsidiaries), and no loss contingency (as defined in Statement of Financial
Accounting Standards No. 5), other than (a) those reflected in the Collective
Financial Statements or disclosed in the notes thereto, (b) commitments made
by Collective or any of its subsidiaries in the ordinary course of its
business which are not in the aggregate material to Collective and its
subsidiaries, taken as a whole, and (c) liabilities arising in the ordinary
course of its business since June 30, 1996, which are not in the aggregate
material to Collective and its subsidiaries, taken as a whole. Other than as
may be reported in the Forms 10-Q of Collective referred to in Section 2.02,
neither Collective nor any of its subsidiaries has, since June 30, 1996,
become obligated on any debt due in more than one year from the date of this
Agreement in excess of $1,000,000, other than intra-corporate debt and
deposits received, repurchase agreements and borrowings from the Federal
Reserve Bank of New York or the Federal Home Loan Bank of New York entered
into in the ordinary course of business.
 
  Section 2.05. Absence of Litigation; Agreements with Bank Regulators. There
is no outstanding order, injunction or decree of any court or governmental or
self-regulatory body against or affecting Collective or any of its
subsidiaries which materially and adversely affects Collective and its
subsidiaries, taken as a whole, and there are no actions, arbitrations,
claims, charges, suits, investigations or proceedings (formal or informal)
material to Collective and its subsidiaries, taken as a whole, pending or, to
Collective's knowledge, threatened, against or involving Collective or any of
its subsidiaries or their officers or directors (in their capacity as such) in
law or equity or before any court, panel or governmental agency, except as may
be disclosed in the Forms 10-K and 10-Q of Collective referred to in Section
2.02. Neither Bank nor Collective is a party to any agreement or memorandum of
understanding with, or is a party to any commitment letter to, or has
submitted a board of directors resolution or similar undertaking to, or is
subject to any order or directive by, or is a recipient of any extraordinary
supervisory letter from, any governmental or regulatory authority which
restricts materially the conduct of its business, or in any manner relates to
material statutory or regulatory noncompliance discovered in any regulatory
examinations, its capital adequacy, its credit or reserve policies or its
management. Neither Bank nor Collective has been advised by any governmental
or regulatory authority that it is contemplating issuing or requesting (or is
considering the appropriateness of issuing or requesting) any of the
foregoing. Neither Bank nor Collective has failed to resolve to the
satisfaction of the applicable regulatory agency any significant deficiencies
cited by any such agency in its most recently completed examination of each
aspect of Bank's and
 
                                      A-8
<PAGE>
 
Collective's business nor has Bank or Collective been advised of any
significant deficiencies by any such agency in connection with any current
examination of Bank or Collective by any such agency.
 
  Section 2.06. Brokers' Fees. Collective has entered into this Agreement with
Summit as a result of direct negotiations without the assistance or efforts of
any finder, broker, financial advisor or investment banker, other than Merrill
Lynch, Pierce, Fenner & Smith Incorporated ("Merrill Lynch"). Collective
Schedule 2.06 consists of true and complete copies of all agreements between
Collective and Merrill Lynch with respect to the transactions contemplated by
this Agreement or similar transactions.
 
  Section 2.07. Material Filings. At the time of filing, all filings made by
Collective and its subsidiaries after June 30, 1990 with the SEC and the
appropriate bank regulatory authorities do not or did not contain any untrue
statement of a material fact and do not or did not omit to state any material
fact required to be stated herein or therein or necessary to make the
statements contained therein, in light of the circumstances under which they
were made, not misleading. To the extent such filings were subject to the
Securities Act or Exchange Act, such filings complied in all material respects
with the Securities Act or Exchange Act, as appropriate, and all applicable
rules and regulations thereunder of the SEC. Collective and its subsidiaries
have since June 30, 1993 timely made all filings required by the Securities
Act and the Exchange Act, Federal and state banking laws and regulations and
the rules and regulations of the NASD and any other self-regulatory
organization, and have paid all fees and assessments due and payable in
connection therewith.
 
  Section 2.08. Corporate Action. Assuming due execution and delivery by
Summit, and subject to the requisite approval by the shareholders of
Collective of this Agreement, the Merger and the other transactions
contemplated hereby in accordance with Collective's Restated Certificate of
Incorporation and the Delaware Law at a meeting of such holders to be duly
called and held, Collective has the corporate power and is duly authorized by
all necessary corporate action to execute, deliver and perform this Agreement.
The Board of Directors of Collective has taken all action required by law, its
Restated Certificate of Incorporation, its By-Laws or otherwise (i) to
authorize the execution and delivery of this Agreement and (ii) for
shareholders of Collective to approve this Agreement and the transactions
contemplated hereby including the Merger by a simple majority of the votes
cast at the meeting held in accordance with Section 4.03. This Agreement is a
valid and binding agreement of Collective enforceable in accordance with its
terms except as such enforcement may be limited by applicable principles of
equity, and by bankruptcy, insolvency, fraudulent transfer, moratorium or
other similar laws of general applicability presently or hereafter in effect
affecting the enforcement of creditors' rights generally and banks the
deposits of which are insured by the Federal Deposit Insurance Corporation.
The Board of Directors of Collective in authorizing the execution of this
Agreement has determined to recommend to the shareholders of Collective the
approval of this Agreement, the Merger and the other transactions contemplated
hereby.
 
  Section 2.09. Absence of Changes. There has not been, since June 30, 1996,
any Collective Material Adverse Change except as may have been reported in the
Forms 10-Q of Collective referred to in Section 2.02. Except as may have been
reported in said Forms 10-Q of Collective, neither Collective nor any of its
subsidiaries has since June 30, 1996: (a) (i) declared, set aside or paid any
dividend or other distribution in respect of its capital stock, other than
dividends from subsidiaries to Collective or other subsidiaries of Collective,
and an ordinary cash dividend to Collective shareholders of $0.25 per share
per fiscal quarter, or, (ii) except as disclosed in Collective Schedule 2.09,
directly or indirectly purchased, redeemed or otherwise acquired any shares of
such stock held by persons other than Collective and its subsidiaries; (b)
incurred current liabilities since that date other than in the ordinary course
of business; (c) sold, exchanged or otherwise disposed of any of their assets
except in the ordinary course of business; (d) except with respect to the
employment agreement and termination agreements disclosed in Collective
Schedule 2.09 ("Officer Agreements"), made any officers' salary increase or
wage increase not consistent with past practices, entered into any employment,
consulting, severance or change of control contract with any present or former
director, officer or salaried employee, or instituted any employee or director
welfare, bonus, stock option, profit-sharing, retirement, severance or other
benefit plan or arrangement or modified any of the foregoing so as to increase
its obligations thereunder in any material respect; (e) suffered any taking by
condemnation or eminent domain or other damage, destruction or loss in excess
of $250,000, whether or not covered by insurance, adversely affecting its
business, property or assets, or waived any rights of
 
                                      A-9
<PAGE>
 
value in excess of $250,000; (f) entered into transactions other than in the
ordinary course of business which in the aggregate exceeded $1,000,000; or (g)
acquired assets or capital stock of another company of whatsoever amount,
except in a fiduciary capacity or in the course of securing or collecting
loans or leases.
 
  Section 2.10. Allowance for Loan and Lease Losses. At June 30, 1996 and
thereafter the allowances for loan and lease losses of Collective and its
subsidiaries were and are adequate in all material respects to provide for all
losses on loans and leases outstanding and, to the best of Collective's
knowledge, the loan and lease portfolios of Collective in excess of such
allowances are collectible in the ordinary course of business. Collective
Schedule 2.10 constitutes a list of all loans and leases made by Collective or
any of its subsidiaries that have been "classified" as to quality by any
internal or external auditor, accountant or examiner, and such list is
accurate and complete in all material respects.
 
  Section 2.11. Taxes and Tax Returns. Neither Collective nor any of its
subsidiaries has at any time filed a consent pursuant to Section 341(f) of the
Code or consented to have the provisions of Section 341(f)(2) of the Code
apply to any disposition of a subsection (f) asset (as such term is defined in
Section 341(f)(4) of the Code) owned by Collective or any of its subsidiaries.
None of the property being acquired by Summit or its subsidiaries in the
Merger is property which Summit or its subsidiaries will be required to treat
as being owned by any other person pursuant to the provisions of Section
168(f)(8) of the Internal Revenue Code of 1954, as amended and in effect
immediately prior to the enactment of the Tax Reform Act of 1986 or is "tax-
exempt use property" within the meaning of Section 168(h)(1) of the Code. All
amounts required to be withheld have been withheld from employees by
Collective and each of its subsidiaries for all periods in compliance with the
tax, social security, unemployment and other applicable withholding provisions
of applicable federal, state and local law. Proper and accurate federal, state
and local returns (as defined below) have been timely filed by Collective and
each of its subsidiaries for all periods for which returns were due, including
with respect to employee income tax withholding, social security, unemployment
and other applicable taxes (as defined below), and the amounts shown thereon
to be due and payable, as well as any interest, additions, and penalties due
with respect to completed and settled examinations or concluded litigation
relating to Collective or any of its subsidiaries, have been paid in full or
adequate provision therefor has been included on the books of Collective or
its appropriate subsidiary. Other than franchise tax returns filed by
Collective with the State of Delaware, neither Collective nor any of its
subsidiaries is required to file tax returns with any state other than the
State of New Jersey. Provision has been made on the books of Collective or its
appropriate subsidiary for all unpaid taxes, whether or not disputed, that may
become due and payable by Collective or any of its subsidiaries in future
periods in respect of transactions, sales or services previously occurring or
performed. The Internal Revenue Service ("IRS") has audited the consolidated
federal income tax returns of Collective for all taxable years ended on or
prior to        and the State of New Jersey has audited the New Jersey income
tax returns of Collective and its subsidiaries for all taxable years ended on
or prior to       . Neither Collective nor any of its subsidiaries is subject
to an audit or review of its tax returns by any state other than the State of
New Jersey. Collective is not and has not been a United States real property
holding corporation as defined in Section 897(c)(2) of the Code during the
applicable period specified in Section 897(c)(1)(A)(ii) of the Code. Neither
Collective nor any of its subsidiaries is currently a party to any tax sharing
or similar agreement with any third party. There are no material matters,
claims, assessments, examinations, notices of deficiency, demands for taxes,
refund litigation, proceedings, audits or proposed deficiencies pending or, to
Collective's knowledge, threatened against Collective or any of its
subsidiaries, including a claim or assessment by any authority in a
jurisdiction where Collective or any of its subsidiaries do not file tax
returns and Collective or any such subsidiary is subject to taxation, and
there have been no waivers of statutes of limitations or agreements related to
assessments or collection in respect of any federal, state or local taxes.
Neither Collective nor any of its subsidiaries has agreed to or is required to
make any adjustment pursuant to Section 481(a) of the Code by reason of a
change in accounting method initiated by Collective or any of its
subsidiaries, and neither Collective nor any of its subsidiaries has any
knowledge that the IRS has proposed any such adjustment or change in
accounting method. Collective and its subsidiaries have complied in all
material respects with all requirements relating to information reporting,
including tax identification number reporting, and withholding (including
back-up withholding) and other requirements relating to the reporting of
interest, dividends and other reportable payments under the Code
 
                                     A-10
<PAGE>
 
and state and local tax laws and the regulations promulgated thereunder and
other requirements relating to reporting under federal law including record
keeping and reporting on monetary instruments transactions.
 
  "Taxes" shall mean all taxes, charges, fees, levies, penalties or other
assessments imposed by any United States Federal, state, local, or foreign
taxing authority, including, but not limited to, income, excise, property,
sales, transfer, franchise, payroll, withholding, social security or other
taxes, including any interest, penalties or additions attributable thereto.
"Return" shall mean any return, report, information return or other documents
(including any related or supporting information) with respect to Taxes.
 
  Section 2.12. Properties. Collective has, directly or through its
subsidiaries, good and marketable title to all of its properties and assets,
tangible and intangible, including those reflected in the most recent
consolidated balance sheet included in the Collective Financial Statements
(except individual properties and assets disposed of since that date in the
ordinary course of business), which properties and assets are not subject to
any mortgage, pledge, lien, charge or encumbrance other than as reflected in
the Collective Financial Statements or which in the aggregate do not
materially adversely affect or impair the operation of Collective and its
subsidiaries taken as a whole. Collective and each of its subsidiaries enjoys
peaceful and undisturbed possession under all material leases under which it
or any of its subsidiaries is the lessee, where the failure to enjoy such
peaceful and undisturbed possession would be likely to have a Collective
Material Adverse Effect, and none of such leases contains any unusual or
burdensome provision which would be likely to materially and adversely affect
or impair the operations of Collective and its subsidiaries taken as a whole.
 
  Section 2.13. Condition of Properties; Insurance. All real and tangible
personal properties owned by Collective or any of its subsidiaries or used by
Collective or any of its subsidiaries in its business are in a good state of
maintenance and repair, are in good operating condition, subject to normal
wear and tear, conform in all material respects to all applicable ordinances,
regulations and zoning laws, and are adequate for the business conducted by
Collective or such subsidiary subject to exceptions which are not, in the
aggregate, material to Collective and its subsidiaries, taken as a whole.
Collective and each of its subsidiaries maintains insurance (with companies
which, to the best of Collective's knowledge, are authorized to do business in
New Jersey) against loss relating to such properties and such other risks as
companies engaged in similar business located in the State of New Jersey,
would, in accordance with good business practice, be customarily insured in
amounts which are customary, usual and prudent for corporations or banks, as
the case may be, of their size. Such policies are in full force and effect and
are carried in an amount and form and are otherwise adequate to protect
Collective and each of its subsidiaries from any adverse loss resulting from
risks and liabilities reasonably foreseeable at the date hereof, and are
disclosed on Collective Schedule 2.13. All material claims thereunder have
been filed in a due and timely fashion. Except as disclosed on Collective
Schedule 2.13, since January 1, 1991, neither Collective nor any of its
subsidiaries has been refused insurance for which it has applied or had any
policy of insurance terminated (other than at its request) nor have they
received notice from any insurance carrier that (i) such insurance will be
canceled or that coverage thereunder will be reduced or eliminated or (ii)
premium costs with respect to such insurance will be increased.
 
  Section 2.14. Contracts.
 
  (a) Except as set forth in Collective Schedule 2.14(a), neither Collective
nor any of its subsidiaries is a party to and neither they nor any of their
assets are bound by any written or oral lease or license with respect to any
property, real or personal, as tenant or licensee involving an annual
consideration in excess of $250,000.
 
  (b) Except as set forth in Collective Schedule 2.09(a) or 2.14(b), neither
Collective nor any of its subsidiaries is a party to and neither they nor any
of their assets are bound by any written or oral: (i) employment or severance
contract (including, without limitation, any Collective bargaining contract or
union agreement) or other agreement with any director, executive officer or
other key employee of Collective or any subsidiary, the benefits of which are
contingent, or the terms of which are materially altered, upon the occurrence
of a transaction involving Collective or any of its subsidiaries of the nature
contemplated by this Agreement which is not terminable without penalty by
Collective or a subsidiary, as appropriate, on 60 days or less notice; (ii)
 
                                     A-11
<PAGE>
 
contract or commitment for capital expenditures in excess of $250,000 in the
aggregate for any one project or in excess of $1,000,000 in the aggregate for
all projects; (iii) contract or commitment whether or not made in the ordinary
course of business for the purchase of materials or supplies or for the
performance of services involving consideration in excess of $250,000
(including advertising and consulting agreements, data processing agreements,
and retainer agreements with attorneys, accountants, actuaries, or other
professionals); (iv) contract or option to purchase or sell any real or
personal property other than OREO property involving consideration in excess
of $250,000; (v) agreement or plan, including any stock option plan, stock
appreciation rights plan, restricted stock plan, stock purchase plan, or any
other non-qualified compensation plan, any of the benefits of which will be
increased, or the vesting of the benefits of which will be accelerated, by the
occurrence of any of the transactions contemplated by this Agreement or the
value of any of the benefits of which will be calculated on the basis of any
of the transactions contemplated by this Agreement, (vi) agreement containing
covenants that limit the ability of Collective or any of its subsidiaries to
compete in any line of business or with any person, or that involve any
restriction on the geographic area in which or method by which, Collective
(including any successor thereof) or any of its subsidiaries may carry on its
business (other than as may be required by law or any Regulatory Agency),
(vii) agreement which by its terms limits the payment of dividends by
Collective or any of its subsidiaries, (viii) contract (other than this
Agreement) limiting the freedom of Collective or its subsidiaries to engage in
any type of banking or bank-related business permissible under law; (ix)
contract, plan or arrangement which provides for payments of benefits payable
to any participant therein or party thereto, and which might render any
portion of any such payments or benefits subject to disallowance of deduction
therefor as a result of the application of Section 280G of the Code or (x)
other contracts material to the business of Collective and its subsidiaries
taken as a whole and not made in the ordinary course of business.
 
  (c) Neither Collective nor any of its subsidiaries is a party to or
otherwise bound by any contract, agreement, plan, lease, license, commitment
or undertaking which, in the reasonable opinion of management of Collective,
is materially adverse, onerous, or harmful to any aspect of the business of
Collective and its subsidiaries taken as a whole.
 
  Section 2.15. Pension and Benefit Plans.
 
  (a) Neither Collective nor any of its subsidiaries maintains an employee
pension benefit plan, within the meaning of Section 3(2) of the Employee
Retirement Income Security Act of 1974, as amended ("ERISA"), or has made any
contributions to any such employee pension benefit plan, except employee
pension benefit plans listed in Collective Schedule 2.15(a) (individually a
"Collective Pension Plan" and collectively the "Collective Pension Plans"). In
its present form each Collective Pension Plan complies in all material
respects with all applicable requirements under ERISA and the Code. Each
Collective Pension Plan and the trust created thereunder is qualified and
exempt under Sections 401(a) and 501(a) of the Code, and Collective or the
subsidiary whose employees are covered by such Collective Pension Plan has
received from the IRS a determination letter to that effect and such
determination letter may still be relied on. No event has occurred and there
has been no omission or failure to act which would adversely affect such
qualification or exemption. Each Collective Pension Plan has been administered
and communicated to the participants and beneficiaries in all material
respects in accordance with its terms and ERISA. No employee or agent of
Collective or any subsidiary whose employees are covered by a Collective
Pension Plan has engaged in any action or failed to act in such manner that,
as a result of such action or failure, (i) the IRS could revoke, or refuse to
issue (as the case may be), a favorable determination as to such Collective
Pension Plan's qualification and the associated trust's exemption or impose
any liability or penalty under the Code, or (ii) a participant or beneficiary
or a nonparticipating employee has been denied benefits properly due or to
become due under such Collective Pension Plan or has been misled as to his or
her rights under such Collective Pension Plan. No Collective Pension Plan is
subject to Section 412 of the Code or Title IV of ERISA. No person has engaged
in any prohibited transaction involving any Collective Pension Plan or
associated trust within the meaning of Section 406 of ERISA or Section 4975 of
the Code. There are no pending or threatened claims (other than routine claims
for benefits) against the Collective Pension Plans or any fiduciary thereof
which would subject Collective or any of its subsidiaries to a material
liability. All reports, filings, returns and disclosures and other
communications which have been required to be made to the participants and
beneficiaries, other employees, the Pension Benefit Guaranty Corporation
("PBGC"), the SEC,
 
                                     A-12
<PAGE>
 
the IRS, the U.S. Department of Labor or any other governmental agency
pursuant to the Code, ERISA, or other applicable statute or regulation have
been made in a timely manner and all such reports, communications, filings,
returns and disclosures were true and correct in all material respects. No
liability has been, or is likely to be, incurred on account of delinquent or
incomplete compliance or failure to comply with such requirements. "ERISA
Affiliate" where used in this Agreement means any trade or business (whether
or not incorporated) which is a member of a group of which Collective is a
member and which is under common control within the meaning of Section 414 of
the Code. Neither Collective nor any of its subsidiaries has any material
liability under ERISA or the Code as a result of its being a member of a group
described in Sections 414(b), (c), (m) or (o) of the Code. There are no
unfunded benefit or pension plans or arrangements, or any individual
agreements whether qualified or not, to which Collective or any of its
subsidiaries or ERISA Affiliates has any obligation to contribute and the
present value of all benefits vested and all benefits accrued under each
Collective Pension Plan which is subject to Title IV of ERISA did not, in each
case, as of the last applicable annual valuation date, exceed the value of the
assets of the Collective Pension Plan allocable to such vested or accrued
benefits. No Collective Pension Plan or any trust created thereunder has been
terminated, nor has there been any "reportable events" with respect to any
Collective Pension Plan, as that term is defined in Section 4043 of ERISA
since January 1, 1990. No Collective Pension Plan or any trust created
thereunder has incurred any "accumulated funding deficiency" as such term is
defined in Section 302 of ERISA(whether or not waived). No Collective Pension
Plan is a "multiemployer plan" as that term is defined in Section 3(37) of
ERISA. There has been no change in control of any Collective Pension Plan
since the last effective date of any such change of control disclosed to
Summit in Collective Schedule 2.15(a).
 
  (b) All bonus, deferred compensation, profit-sharing, retirement, pension,
stock option, stock award and stock purchase plans and all other employee
benefit, health and welfare plans, arrangements or agreements, including
without limitation the Collective Stock Plans and medical, major medical,
disability, life insurance or dental plans covering employees generally, other
than the Collective Pension Plans, maintained by Collective or any of its
subsidiaries with an annual cost in excess of $250,000 (collectively
"Collective Benefit Plans") are listed in Collective Schedule 2.15(b) (unless
already listed in Collective Schedule 2.15(a)) and comply in all material
respects with all applicable requirements imposed by the Securities Act, the
Exchange Act, ERISA, the Code, and all applicable rules and regulations
thereunder. The Collective Benefit Plans have been administered and
communicated to the participants and beneficiaries in all material respects in
accordance with their terms and ERISA, and no employee or agent of Collective
or any of its subsidiaries has engaged in any action or failed to act in such
manner that, as a result of such action or failure: (i) the IRS could revoke,
or refuse to issue, a favorable determination as to an Collective Benefit
Plan's qualification and any associated trust's exemption or impose any
liability or penalty under the Code; or (ii) a participant or beneficiary or a
nonparticipating employee has been denied benefits properly due or to become
due under the Collective Benefit Plans or has been misled as to their rights
under the Collective Benefit Plans. There are no pending or threatened claims
(other than routine claims for benefits) against the Collective Benefit Plans
which would subject Collective or any of its subsidiaries to liability. Any
trust which is intended to be tax-exempt has received a determination letter
from the IRS to that effect and no event has occurred which would adversely
affect such exemption. All reports, filings, returns and disclosures required
to be made to the participants and beneficiaries, other employees of
Collective or any of its subsidiaries, the PBGC, the SEC, the IRS, the U.S.
Department of Labor and any other governmental agency pursuant to the Code,
ERISA, or other applicable statute or regulation, if any, have been made in a
timely manner and all such reports, filings, returns and disclosures were true
and correct in all material respects. No material liability has been, or is
likely to be, incurred on account of delinquent or incomplete compliance or
failure to comply with such requirements.
 
  (c) There is no pending or, to Collective's knowledge, threatened
litigation, administrative action or proceeding relating to any Collective
Benefit Plan or Collective Pension Plan. There has been no announcement or
commitment by Collective or any subsidiary of Collective to create an
additional Collective Benefit Plan or Collective Pension Plan, or to amend a
Collective Benefit Plan or Collective Pension Plan, except for amendments
required by applicable law, which may materially increase the cost of such
Collective Benefit Plan or Collective Pension Plan and, except for any plans
or amendments expressly described on Collective Schedule
 
                                     A-13
<PAGE>
 
2.15(a) or Collective Schedule 2.15(b), Collective and its subsidiaries do not
have any obligations for post-retirement or post-employment benefits under any
Collective Benefit Plan (exclusive of any coverage mandated by the
Consolidated Omnibus Reconciliation Act of 1986 ("COBRA") that cannot be
amended or terminated upon more than sixty (60) days' notice without incurring
any liability thereunder. With respect to each Collective Benefit Plan and
Collective Pension Plan to the extent applicable, Collective has supplied or
will promptly supply to Summit a true and complete copy of (A) the most recent
annual report on the applicable form of the Form 5500 series filed with the
IRS with all the attachments filed, (B) such Collective Benefit Plan or
Collective Pension Plan, including amendments thereto, (C) each trust
agreement and insurance contract relating to such plan, including amendments
thereto, (D) the most recent summary plan description for such plan, including
amendments thereto, if the plan is subject to Title I of ERISA, (E) the most
recent actuarial report or valuation if such plan is a pension plan and (F)
the most recent determination letter issued by the IRS if such plan is
qualified under Section 401(a) of the Code. To the extent that any individual
plan or arrangement described under this Section 2.15 does not completely meet
representations made herein, such plan and its variance from the
representation is set forth in Collective Schedule 2.15(a) or Collective
Schedule 2.15(b).
 
  Section 2.16. Fidelity Bonds. Since at least January 1, 1991, Collective and
each of its subsidiaries has continuously maintained fidelity bonds insuring
them against acts of dishonesty in such amounts as are customary, usual and
prudent for organizations of its size and business. All material claims
thereunder have been filed in a due and timely fashion. Since January 1, 1991,
the aggregate amount of all claims under such bonds has not exceeded the
policy limits of such bonds (excluding, except in the case of excess coverage,
a deductible amount of not more than $50,000) and neither Collective nor any
of its subsidiaries is aware of any facts which would form the basis of a
claim or claims under such bonds aggregating in excess of the applicable
deductible amounts under such bonds. Neither Collective nor any of its
subsidiaries has reason to believe that its respective fidelity coverage will
not be renewed by its carrier on substantially the same terms as the existing
coverage, except for possible premium increases unrelated to Collective's and
its subsidiaries' past claim experience.
 
  Section 2.17. Labor Matters. Hours worked by and payment made to employees
of Collective and each of its subsidiaries have not been in violation of the
Fair Labor Standards Act or any applicable law dealing with such matters; and
all payments due from Collective and each of its subsidiaries on account of
employee health and welfare insurance have been paid or accrued as a liability
on the books of Collective or its appropriate subsidiary. Collective is in
compliance in all material respects with all other laws and regulations
relating to the employment of labor, including all such laws and regulations
relating to Collective bargaining, discrimination, civil rights, safety and
health, plant closing (including the Worker Adjustment Retraining and
Notification Act), workers' compensation and the collection and payment of
withholding and Social Security and similar taxes. No labor dispute, strike or
other work stoppage has occurred and is continuing or is to its knowledge
threatened with respect to Collective or any of its subsidiaries. Since
January 1, 1991, no employee of Collective or any of its subsidiaries has been
terminated, suspended, disciplined or dismissed under circumstances which
could constitute a material claim, suit, action, complaint or proceeding
likely to result in a material liability. No employees of Collective or any of
its subsidiaries are unionized nor has such union representation been
requested by any group of employees or any other person within the last two
years. There are no organizing activities involving Collective pending with,
or, to the knowledge of Collective, threatened by, any labor organization or
group of employees of Collective.
 
  Section 2.18. Books and Records. The minute books of Collective and each of
its subsidiaries contain complete and accurate records of and fairly reflect

in Section 4.01 or the consummation of the transactions contemplated by this

giving of notice and failure to cure) result in any payment (severance or
other) or provision of a benefit becoming due from Collective or any of its
subsidiaries or any successor or assign thereof to any director, officer or
employee of Collective or any of its subsidiaries or any successor or assign

stock consisting of 130,000,000 shares of Common Stock, each of par value
$1.20 with attached rights issued pursuant to the Summit Shareholder Rights
Plan, of which 94,152,078 shares were issued and outstanding as of January 31,

<PAGE>
 
  (b) Summit is qualified to transact business in and is in good standing
under the laws of all jurisdictions where the failure to be so qualified would
have a material adverse effect on (i) the business, results of operations,
assets or financial condition of Summit and its subsidiaries on a consolidated
basis, or (ii) the ability of Summit to perform its obligations under, and to
consummate the transactions contemplated by, this Agreement (a "Summit
Material Adverse Effect" or "Summit Material Adverse Change"). However, a
Summit Material Adverse Effect or Summit Material Adverse Change will not
include a change resulting from a change in law, rule, regulation, generally
accepted or regulatory accounting principle or other matter affecting
financial institutions or their holding companies generally or from charges or
expenses incident to the Merger. The bank subsidiaries of Summit are duly
organized, validly existing and in good standing under the laws of their
jurisdiction of organization. Summit and its bank subsidiaries have all
corporate power and authority and all material licenses, franchises,
certificates, permits and other governmental authorizations which are legally
required to own and lease their respective properties, occupy their respective
premises, and to engage in their respective businesses and activities as
presently engaged in. Summit is duly registered as a bank holding company
under the Bank Holding Company Act of 1956, as amended ("BHCA").
 
  (c) All issued shares of the capital stock of Summit and of each of its bank
subsidiaries have been fully paid, were duly authorized and validly issued,
are non-assessable, have been issued pursuant to an effective registration
statement under the Securities Act or an appropriate exemption from
registration under the Securities Act and were not issued in violation of the
preemptive rights of any shareholder. Summit or one of its subsidiaries is the
holder and beneficial owner of all of the issued and outstanding Equity
Securities of its bank subsidiaries. There are no Equity Securities of Summit
outstanding, in existence, the subject of an agreement, or reserved for
issuance, except as set forth at Section 3.01(a) or described at Summit
Schedule 3.01 and except for Summit Stock issuable upon the exercise of
employee stock options granted under stock option plans of Summit, Summit
Stock issuable pursuant to Summit's Dividend Reinvestment and Stock Purchase
Plan, Savings Incentive Plan and 1993 Incentive Stock and Option Plan and the
Agreement and Plan of Merger, dated August 28, 1996, between Summit and B.M.J.
Financial Corp. ("BMJ Merger Agreement") and Series R Preferred Stock issuable
pursuant to the Summit Shareholder Rights Plan.
 
  (d) Except as disclosed on Summit Schedule 3.01, all Equity Securities of
its direct and indirect subsidiaries beneficially owned by Summit or a
subsidiary of Summit are held free and clear of any claims, liens,
encumbrances or security interests.

contained or incorporated in Summit's (a) annual report to shareholders for
the fiscal year ended December 31, 1995, (b) annual report on Form 10-K
pursuant to the Exchange Act for the fiscal year ended December 31, 1995 and
(c) quarterly reports on Form 10-Q pursuant to the Exchange Act for the fiscal
quarters ended March 31, 1996, June 30, 1996 and September 30, 1996 (the
"Summit Financial Statements") are true and correct in all material respects
as of their respective dates and each fairly presents, in accordance with
generally accepted accounting principles consistently applied, the
consolidated balance sheets, statements of income, statements of shareholders'
equity and statements of cash flows of Summit and its subsidiaries at its
respective date and for the period to which it relates. Except as may
otherwise be described therein or in the related notes or in accountants'
reports thereon, the Summit Financial Statements were prepared in accordance
with generally accepted accounting principles consistently applied. The Summit
Financial Statements do not, as of the dates thereof, include any material
asset or omit any material liability, absolute or contingent, or other fact,
the inclusion or omission of which renders the Summit Financial Statements, in
light of the circumstances under which they were made, misleading in any
respect.
 
  Section 3.03. No Conflicts. Summit is not in, and has received no notice of,
violation or breach of, or default under, nor will the execution, delivery and
performance of this Agreement by Summit, or the consummation of the Merger by
Summit upon the terms and conditions provided herein (assuming receipt of the
Required Consents), violate, conflict with, result in the breach of,

cancellation, revocation of, or acceleration under, or result in the creation
or imposition of any lien, charge or encumbrance upon any rights, permits,
licenses, assets or properties material to Summit

and its subsidiaries, taken as a whole, or upon any of the capital stock of
Summit, or constitute an event which could, with the lapse of time, action or
inaction by Summit, or a third party, or the giving of notice and failure to
cure, result in any of the foregoing, under any of the terms, conditions or
provisions, as the case may be, of:

    (b) any law, statute, rule, ruling, determination, ordinance, or
  regulation of any governmental or regulatory authority;

  insurance or indemnity, license, contract, agreement, or other instrument;
 
to which Summit is a party or by which Summit or any of its assets or
properties are bound or committed, the consequences of which would be a Summit
Material Adverse Change, or enable any person to enjoin the transactions
contemplated hereby.
 
  Section 3.04. Absence of Litigation, Agreements with Bank Regulators. There

self-regulatory body against or affecting Summit or its subsidiaries which
materially and adversely affects Summit and its subsidiaries, taken as a
whole, and there are no actions, arbitrations, claims, charges, suits,
investigations or proceedings (formal or informal) material to Summit and its
subsidiaries, taken as a whole, pending or, to Summit's knowledge, threatened,
against or involving Summit or their officers or directors (in their capacity
as such) in law or equity or before any court, panel or governmental agency,
except as may be disclosed in the Forms 10-K and 10-Q of Summit referred to in
Section 3.02 or in the Form 8-K of Summit dated December 10, 1996. Neither

or has submitted a board of directors resolution or similar undertaking to, or
is subject to any order or directive by, or is a recipient of any
extraordinary supervisory letter from, any governmental or regulatory
authority which restricts materially the conduct of its business, or in any
manner relates to its capital adequacy, its credit or reserve policies or its
management. Neither Summit nor any bank subsidiary of Summit, has been advised
by any governmental or regulatory authority that it is contemplating issuing
or requesting (or is considering the appropriateness of issuing or requesting)
any of the foregoing. Summit and the bank subsidiaries of Summit have resolved
to the satisfaction of the applicable regulatory agency any significant
deficiencies cited by any such agency in its most recent examinations of each
aspect of Summit or such bank subsidiary's business except for examinations,
if any, received within the 30 days prior to the date hereof.

appropriate bank regulatory authorities do not contain any untrue statement of
a material fact and do not omit to state any material fact required to be

misleading. To the extent such filings were subject to the Securities Act or
Exchange Act, such filings complied in all material respects with the
Securities Act or Exchange Act, as appropriate, and all applicable rules and
regulations thereunder of the SEC. Summit has since December 31, 1993 timely
made all filings required by the Securities Act and the Exchange Act.
 
  Section 3.06. Corporate Action. Assuming due execution and delivery by
Collective, Summit has the corporate power and is duly authorized by all

The Board of Directors of Summit has taken all action required by law or by
the Restated Certificate of Incorporation or By-Laws of Summit or otherwise to
authorize the execution and delivery of this Agreement. Approval by the
shareholders of Summit of this Agreement, the Merger or the transactions
contemplated by this Agreement are not required by applicable law. This
Agreement is a valid and binding agreement of Summit enforceable in accordance
with its terms except as such enforcement may be limited by applicable

presently or hereafter in effect affecting the enforcement of creditors'
rights generally and banks the deposits of which are insured by the Federal
Deposit Insurance Corporation.

contemplated, pending or completed by any environmental regulatory authority
with respect to any Present Property, Former Property, Loan Property or
Participation Facility which would result in a Summit Material Adverse Change,
(ii) has received any information requests from any environmental regulatory

  Section 3.11. Allowance for Loan and Lease Losses. At December 31, 1995 and
thereafter, the allowances for loan and lease losses of Summit and its

  Section 3.12. Taxes and Tax Returns. Except to the extent not material to

or its appropriate subsidiary. Except to the extent not material to Summit and
its subsidiaries, taken as a whole, provision has been made on the books of
Summit or its appropriate bank subsidiary for all unpaid taxes, whether or not

in future periods in respect of transactions, sales or services previously
occurring or performed. Summit is not and has not been a United States real
property holding corporation as defined in Section 897(c)(2) of the Code
during the applicable period specified in Section 897(c)(1)(A)(ii) of the
Code. Neither Summit nor any of its bank subsidiaries is currently a party to

proceedings, audits or proposed deficiencies pending or, to Summit's
knowledge, threatened against Summit or any of its bank subsidiaries and there
have been no waivers of statutes of limitations or agreements related to
assessments or collection in respect of any Federal, state or local taxes.
Neither Summit nor any of its subsidiaries has agreed to or is required to
make any adjustment pursuant to Section 481(a) of the Code by reason of a
change in accounting method initiated by Summit or any of its subsidiaries
which would result in any additional tax liability, and neither Summit nor any
of its bank subsidiaries has any knowledge that the IRS has proposed any such
adjustment or change in accounting method which would result in any additional
tax liability. Summit and its subsidiaries have complied in all material
respects with all requirements relating to information reporting and
withholding (including back-up withholding) and other requirements relating to
the reporting of interest, dividends and other reportable payments under the
Code and state and local tax laws and the regulations promulgated thereunder
and other requirements relating to reporting under Federal law including
record keeping and reporting on monetary instruments transactions.
 
  Section 3.13. Properties. Summit, directly or through its subsidiaries, has
good and marketable title to all of its properties and assets, tangible and
intangible, including those reflected in the most recent consolidated balance
sheet included in the Summit Financial Statements (except properties and
assets disposed of since that date in the ordinary course of business and OREO
property disposed of since that date), which properties and assets are not
subject to any mortgage, pledge, lien, charge or encumbrance other than as
reflected in the Summit Financial Statements or which in the aggregate do not
materially adversely affect or impair the operation of Summit and its
subsidiaries taken as a whole. Summit and each of its subsidiaries enjoys
peaceful and undisturbed possession under all material leases under which it
or any of its subsidiaries is the lessee, where the failure to enjoy such
peaceful and undisturbed possession would be likely to have a material adverse
effect on Summit and its subsidiaries taken as a whole.

been in violation of the Fair Labor Standards Act or any applicable law
dealing with such matters; and all payments due from Summit and each of its
bank subsidiaries on account of employee health and welfare insurance have
been paid or accrued as a liability on the books of Summit or its appropriate

proxy statement-prospectus constituting part of the Registration Statement
("Proxy-Prospectus") that will be used by Collective to solicit shareholders
of Collective for approval of the Merger. In connection therewith, Collective

the Federal Reserve System (the "Federal Reserve Board") and any other
governmental or regulatory consents or approvals or the taking of any other
governmental or regulatory action necessary to consummate the Merger without a
material adverse effect on the business, results of operations, assets or
financial condition of the Surviving Corporation and its subsidiaries, taken
as a whole (the "Required Consents"). Summit, reasonably in advance of making
such filings, will provide Collective and its counsel a reasonable opportunity
to comment on such filings and regulatory applications and will give due
consideration to any comments of Collective and its counsel before making any
such filing or application, and Summit will provide Collective and its counsel
with copies of all such filings and applications at the time filed if such
filings and applications are made at any time before the Effective Time.

applications to appropriate regulatory agencies for approval of the Merger,
and all information furnished by Collective to Summit pursuant to this
Agreement or in connection with obtaining Required Consents, will comply in

and its subsidiaries taken as a whole, and (g) any written notice or other
communication from any third party alleging that the consent of such third
party is or may be required in connection with the transactions contemplated
by this Agreement including the Merger. Collective agrees that the delivery of
such notice shall not constitute a waiver by Summit of any of the provisions
of Articles VI or VII.
 
  Section 4.03. Meeting of Shareholders. Collective will call a meeting of its
shareholders for the purpose of voting upon this Agreement, the Merger and the
transactions contemplated hereby to be held as promptly as practicable and, in

cause to be furnished nonpublic information and may participate in such
discussions directly or through its representatives concerning an Acquisition
Proposal, if such Board of Directors has determined, after having consulted

the failure to provide such nonpublic information or participate in such
discussions would cause the members of such Board of Directors to breach their
fiduciary duties under applicable laws, and, provided, further, that
Collective shall first obtain a confidentiality agreement in customary form
and containing at least the confidentiality provisions set forth at Sections
4.13 and 5.08. "Acquisition Proposal" is hereby defined to be any offer,

agency or else stand liable for contempt or suffer other censure or penalty,
Summit may disclose such information to such tribunal or governmental body or
agency without liability hereunder and shall so notify Collective in advance
to the extent practicable. This Section 5.08 shall survive any termination of
this Agreement.
 
  Section 5.09. Further Transactions. Summit continually evaluates possible
acquisitions and may prior to the Effective Time enter into one or more
agreements providing for, and may consummate the acquisition by it of another
bank, association, bank holding company, savings and loan holding company or
other company (or the assets thereof) for consideration that may include
Summit Stock. In addition, prior to the Effective Time, Summit may, depending
on market conditions and other factors, otherwise determine to issue equity-
linked or other securities for financing purposes. Notwithstanding the
foregoing, Summit will not take any such action that would (i) prevent the
transactions contemplated hereby from qualifying as a reorganization within
the meaning of Section 368 of the Code or (ii) materially impede or delay
receipt of any Required Consent or the consummation of the transactions
contemplated by this Agreement for more than 60 days.
 
  Section 5.10. Indemnification.
 
  (a) Summit shall indemnify, and advance expenses in matters that may be
subject to indemnification to, persons who served as directors and officers of
Collective or any subsidiary of Collective on or before the Effective Time
with respect to liabilities and claims (and related expenses, including fees
and disbursements of counsel) made against them resulting from their service
as such prior to the Effective Time in accordance with and subject to the
requirements and other provisions of the Restated Certificate of Incorporation
and By-Laws of Summit in effect on the date of this Agreement and applicable
provisions of law to the same extent as Summit is obliged thereunder to
indemnify and advance expenses to its own directors and officers with respect
to liabilities and claims made against them resulting from their service for
Summit.
 
  (b) Subject to Collective's obligation set forth at Section 4.18: For a
period of six (6) years after the Effective Time, Summit will use its best
efforts to provide to the persons who served as directors or officers of
Collective or any subsidiary of Collective on or before the Effective Time
insurance against liabilities and claims (and related expenses) made against
them resulting from their service as such prior to the Effective Time
comparable in coverage to that provided by Summit to its own directors and
officers, but, if not available on commercially reasonable terms, then
coverage substantially similar in all material respects to the insurance
coverage provided to them in such capacities at the date hereof; provided,
however, that in no event shall Summit be required to expend more than 200% of
the current amount expended by Collective on an annual basis (the "Insurance
Amount") to maintain or procure insurance coverage pursuant hereto, and,
further provided, that if Summit is unable to maintain or obtain the insurance
called for by this Section 5.10, Summit shall use its best efforts to obtain
as much comparable insurance as is available for the Insurance Amount.
 
  (c) This Section 5.10 shall be construed as an agreement as to which the
directors and officers of Collective referred to herein are intended to be
third party beneficiaries and shall be enforceable by the such persons and
their heirs and representatives.
 
  Section 5.11. Employee Matters.
 
  (a) After the Effective Time, Summit may in its discretion maintain,
terminate, merge or dispose of the Collective Plans; provided, however, that
any action taken by Summit shall comply with ERISA and any other
 
                                     A-29
<PAGE>
 
applicable laws, including laws regarding the preservation of employee pension
benefit plan benefits and, provided further, that if Summit maintains a plan
available to all its employees generally which is similar in benefits,
character or nature to, or which covers risks similar to those covered by, an
Collective Plan which is available to all Collective employees generally,
then, if such Collective Plan is terminated by Summit or is otherwise rendered
inactive by Summit, Summit shall offer to the former employees of Collective
affected by such plan termination or cessation of activity the opportunity to
participate in the similar plan of Summit without being subject to any
exclusions due to pre-existing conditions and such employees shall be given
credit for years of service with Collective for purposes of eligibility,
vesting and benefit accrual purposes, except benefit accruals under the Summit
Retirement Plan and any supplemental retirement plans of Summit and, during
the applicability of the Severance Arrangement (as defined at Section 5.11(c)
below) but only during the applicability of the Severance Arrangement, any
severance plans, policies or practices of Summit.
 
  (b) After the Effective Time, Collective employees shall not be entitled to
participate automatically in benefits plans, programs or arrangements of
Summit not maintained by Summit for its employees generally, including without
limitation bonus plans, stock option plans, stock award plans, severance plans
and reduction in force plans, but shall be allowed to participate if and only
if selected for participation by the persons authorized by the terms of such
plans to select participants.
 
  (c) Any employee of Collective or a subsidiary of Collective at the
Effective Time whose employment is terminated by Summit, other than for cause,
within twelve (12) months of the Effective Time shall receive, upon executing
a document (in form satisfactory to Summit in its sole discretion) which
releases Summit from all claims relating to such employee's employment by
Collective and Summit, a lump sum payment equal to the sum of (i) and (ii),
where:
 
    (i) is the greater of (A) such employee's gross weekly salary multiplied
  by four, or (B) the product obtained by multiplying such employee's gross
  weekly salary multiplied by two times the number of full years of service
  completed by such employee prior to the termination of employment, and
 
    (ii) (only in the event less than 60 days advance notice is provided to a
  particular terminated employee) is the product of (A) the difference
  obtained by subtracting from 60 the number of days of advance notice of
  termination received by a particular employee (a negative difference shall
  for purposes of this Section 5.11 be treated as a zero), and (B) the
  employee's annual salary rate at the time of the termination of employment
  divided by 365;
 
provided, however, that no employee of Collective or a subsidiary of
Collective shall be eligible to receive the payment provided for above if such
employee is offered a position by Summit which is similar in job content to
the position held by such employee with Collective or its subsidiary and is
located at a reasonably accessible location. (The terms and conditions
governing severance in this Section 5.11(c) are sometimes referred to herein
as the "Severance Arrangement").
 
  (d) Summit shall assume the obligations of Collective under the Officer
Agreements.

assumptions contained in the Tax Opinion being untrue.

by any state or federal agency, and no action, suit, arbitration or proceeding
before any court, state or federal agency, panel or governmental or regulatory

any of its subsidiaries, or Collective or any of its subsidiaries, that is
material to the Merger or to the financial condition of Summit and its
subsidiaries taken as a whole or Collective and its subsidiaries taken as a
whole, as the case may be. At the Closing Date, no order, decree, judgment, or

precedent to its obligation to close under Article VI shall not have been met,
the Board of Directors of such party may terminate this Agreement by giving
written notice of such termination to the other party. Furthermore, the Board
of Directors of either party may terminate this Agreement in the event that:
 
    (i) the shareholders of Collective at the meeting of shareholders
  contemplated by Section 4.03, called for the purpose of approving the
  Merger, this Agreement and the transactions contemplated by this Agreement,
  upon voting, shall have failed to approve the Merger, this Agreement and
  the transactions contemplated hereby by the requisite vote, or
 
    (ii) a material breach of a warranty or representation or covenant made
  by the other party shall have occurred and such breach has not been cured,
  or is not capable of being cured, within 30 days after written notice of
  the existence thereof shall have been given to the other party (provided
  that the terminating party is not then in material breach of any
  representation, warranty, covenant or other agreement contained herein);
 
    (iii) Collective's investment banker is unable to deliver to Collective
  by July 31, 1997 the opinion required by Section 8.07; or
 
    (iv) the Closing is not consummated on or before January 1, 1998, unless
  the failure of such occurrence shall be due solely to the failure of the
  party seeking to terminate this Agreement to perform or observe its
  agreements set forth in this Agreement required to be performed or observed
  by such party on or before the Closing Date.
 
  (b) If either party shall refuse to close because, on the date on which the
Closing must be held as determined by Section 9.01, all the conditions to its
obligation to close (other than a condition set forth in Article VI) shall not
have been met (other than a failure of the condition set forth at Section 7.09
or 8.09 due to the circumstances set forth in Section 9.02(a)(i) hereof, a
failure of the condition set forth at Section 8.07 due to the circumstances
set forth at Section 9.02(a)(iii) hereof or a refusal of Summit to close due
to a failure of the condition set forth at Section 7.12 hereof), the Board of
Directors of such party may terminate this Agreement by giving written notice
of such termination to the other party.
 
  (c) The Board of Directors of Summit may terminate this Agreement if
Collective does not execute and deliver the Option Agreement by the day
immediately following the date hereof.
 
  (d) (1) The Board of Directors of Collective may terminate this Agreement at
any time during the ten-day period commencing the second day after the
Determination Date if
 
    (i) the Average Closing Price of a share of Summit Stock is less than
  $39.00, and
 
    (ii) the quotient obtained by dividing the Average Closing Price (as
  defined below) by $47.50 is more than .18 less than the quotient obtained
  by dividing the Index Price (as defined below) on the Determination Date
  (as defined below) by the Index Price on the Starting Date (as defined
  below).
 
  (2) For purposes of this Section 9.02(d)(2):
 
    (i) "Average Closing Price" means the average of the closing prices of a
  share of Summit Stock on the NYSE-Composite Transactions List (as reported
  in the Wall Street Journal or, in the absence thereof, as reported by

  for the 30 consecutive full trading days, ending on the Determination Date,
  on which one share of Summit Stock is traded.
 
    (ii) "Determination Date" means the date on which the Required Consent of
  the Federal Reserve Board shall have been received.

    (iii) "Index Group" means the 20 bank holding companies listed below, the
  common stocks of all of which shall be publicly traded and as to which
  there shall not have been, since the Starting Date and before the
  Determination Date, any public announcement of a proposal for such company
  to be acquired or for such company to acquire another company or companies
  in transactions with a value exceeding 25% of the acquiror's market
  capitalization. In the event that any such company or companies are removed
  from the Index Group, the weights (which shall be determined based upon the
  number of outstanding shares of common stock) shall be redistributed
  proportionately for purposes of determining the Index Price. If any company
  belonging to the Index Group or Summit declares or effects a stock
  dividend, reclassification, recapitalization, split-up, combination,
  exchange of shares, or similar transaction between the Starting Date and
  the Determination Date, the prices for the common stock of such company or
  Summit shall be appropriately adjusted for the purposes of applying this
  Section 9.02(d). The 20 bank holding companies and the weights attributed
  to them are as follows:

                        (DATED FEBRUARY 27, 1997)     
   
  This Amendment No. 1, dated May 27, 1997, to the Agreement and Plan of
Merger, dated February 27, 1997 (the "Agreement"), is entered into by and
between Summit Bancorp., a New Jersey business corporation ("Summit") and
Collective Bancorp, Inc., a Delaware business corporation ("Collective").
Summit and Collective have determined to amend the Agreement to clarify
certain provisions and to facilitate the transactions contemplated thereby.
       
  NOW, THEREFORE, in consideration of the premises and the representations,
warranties, covenants and agreements contained herein and in the Agreement,
the parties hereto, intending to be legally bound, agree as follows:     
   
  1. Section 2.11 of the Agreement is amended in its entirety to read as
follows:     
     
    Section 2.11 Taxes and Tax Returns

    returns that it was required to file without regard to economic nexus.
    All such income tax returns were correct and complete in all material
    respects. All income taxes owed by any of Collective and its
    subsidiaries (whether or not shown on any income tax return) have been
    paid.     
       
      (b) There is no material dispute or claim concerning any income tax
    liability of any of Collective and its subsidiaries either (i) claimed
    or raised by any authority in writing or (ii) as to which any of
    Collective and the directors and officers of Collective and its
    subsidiaries has knowledge based upon personal contact with any agent
    of such authority.     
       
      (c) Collective Schedule 2.11 lists all federal and state income tax
    returns filed with respect to any of Collective and its subsidiaries
    for taxable periods ended on or after December 31, 1993. Collective has
    delivered to Summit correct and complete copies of all federal income
    tax returns, examination reports, and statements of deficiencies
    assessed against, or agreed to by any of Collective and its
    subsidiaries since December 31, 1993. None of Collective and its
    subsidiaries has waived any statute of limitations in respect of income
    taxes or agreed to any extension of time with respect to an income tax
    assessment or deficiency.     
       
      (d) Collective and its subsidiaries have not filed a consent under
    Code (S)341(l) concerning collapsible corporations. None of Collective
    and its subsidiaries has been a United States real property holding
    corporation within the meaning of Code (S)897(c)(2) during the
    applicable period specified in Code (S)897(c)(l)(A)(ii). None of
    Collective and its subsidiaries is a party to any tax allocation or
    sharing agreement other than among members of the current affiliated
    group. None of Collective and its subsidiaries (i) has been a member of

    has any liability for the taxes of any person (other than Collective
    and its subsidiaries) under Reg. (S)1.1502-6 (or any similar provision
    of state, local, or foreign law), as a transferee or successor, by
    contract, or otherwise, other than the former Continental
    Bancorporation and subsidiaries which joined the current affiliated
    group on October 1, 1996 by way of merger.     
       
      (e) The income taxes of Collective and its subsidiaries (i) did not,
    as of the most recent fiscal month end, exceed by any material amount
    the reserves for income tax liabilities set forth on the face of the
    most recent balance sheet (rather than in any notes thereto) and (ii)
    will not exceed by any material amount that reserve as adjusted for
    operations and transactions through the closing date in accordance with
    the past custom and practice of Collective and its subsidiaries in
    filing their income tax returns.

Board of Directors
Collective Bancorp, Inc.
158 Philadelphia Avenue
Egg Harbor City, NJ 08215
 
Members of the Board:
   
  Summit Bancorp. ("Summit") and Collective Bancorp, Inc. ("Collective") have
entered into an Agreement and Plan of Merger (the "Agreement") dated February
27, 1997 pursuant to which Collective will be merged with and into Summit in a
transaction (the "Merger") in which each outstanding share of Collective's
common stock, par value $0.01 per share (the "Collective Shares"), will be
converted into the right to receive 0.895 shares (the "Exchange Ratio") of the
common stock, par value $1.20 per share, of Summit (the "Summit Shares"), all
as set forth more fully in the Agreement. In connection with the Merger, the
parties have also entered into the Stock Option Agreement, dated February 28,
1997, (the "Option Agreement") pursuant to which Collective has granted to
Summit an option to acquire, under certain circumstances, 19.9% of outstanding
Collective Shares, as set forth more fully in the Option Agreement.     
 
  You have asked us whether, in our opinion, the proposed Exchange Ratio in the
Merger is fair to the shareholders of Collective from a financial point of
view.
 
  In arriving at the opinion set forth below, we have, among other things:
     
   (1) Reviewed Collective's Annual Reports on Form 10-K and related audited
     financial information for the three fiscal years ended June 30, 1996 and
     Collective's Quarterly Reports on Form 10-Q and the related unaudited
     financial information for the quarterly periods ended September 30,
     1996, December 31, 1996 and March 31, 1997;     
     
   (2) Reviewed Summit's Annual Reports on Form 10-K and related audited
     financial information for the three fiscal years ended December 31, 1996
     and Summit's Quarterly Report on Form 10-Q and the related unaudited
     financial information for the quarterly period ended March 31, 1997;
            
   (3) Reviewed certain limited financial information, including financial
     forecasts, relating to the respective businesses, earnings, assets,
     liabilities and prospects of Collective and Summit furnished to us by
     senior management of Collective and Summit as well as projected cost
     savings and related expenses expected to result from the Merger (the
     "Expected Savings") furnished to us by senior management of Summit;     
 
   (4) Conducted certain limited discussions with members of senior
     management of Collective and Summit concerning respective financial
     condition, businesses, earnings, assets, liabilities, operations,
     regulatory condition, financial forecasts, contingencies and prospects,
     of Collective and Summit and their respective view as to the future
     financial performance of Collective, Summit and the combined entity, as
     the case may be, following the Merger;
 
                                      B-1

[LOGO]Merrill Lynch
 
   (5) Reviewed the historical market prices and trading activity for the
     Collective Shares and the Summit Shares and compared them with that of
     certain publicly traded companies which we deemed to be relevant;
 
   (6) Compared the respective results of operations of Collective and Summit
     with those of certain publicly traded companies which we deemed to be
     relevant;
 
   (7) Compared the proposed financial terms of the Merger contemplated by
     the Agreement with the financial terms of certain other mergers and
     acquisitions which we deemed to be relevant;
 
   (8) Reviewed the amount and timing of the Expected Savings for Collective
     and Summit following the Merger as prepared, and discussed with us, by
     the senior management of Summit;
 
   (9) Considered, based upon information provided by Summit's senior
     management, the pro forma impact of the transaction on the earnings and

  (10) Reviewed the Agreement and Plan of Merger and the Option Agreement;
     and
 
  (11) Reviewed such other financial studies and analyses and performed such
     other investigations and took into account such other matters as we
     deemed appropriate.
   
  In preparing our opinion, with your consent we have assumed and relied on
the accuracy and completeness of all information supplied or otherwise made
available to us by Collective and Summit, including that contemplated in the
numbered items above, and we have not assumed responsibility for independently
verifying such information or undertaken an independent evaluation or
appraisal of the assets or liabilities, contingent or otherwise, of Collective
or Summit or any of their subsidiaries, nor have we been furnished any such
evaluation or appraisal. We are not experts in the evaluation of allowances
for loan losses and, with your consent, we have not made an independent
evaluation of the adequacy of the allowance for loan losses of Collective or
Summit, nor have we reviewed any individual credit files relating to Summit or
Collective and, with your consent, we have assumed that the respective
aggregate allowance for loan losses for both Summit and Collective is adequate
to cover such losses and will be adequate on a pro forma basis for the
combined entity. In addition, we have not conducted any physical inspection of
the properties or facilities of Collective or Summit. With your consent, we
have also assumed and relied upon the senior management of Collective and
Summit as to the reasonableness and achievability of the financial forecasts
(and the assumptions and bases therefor) provided to, and discussed with us.
In that regard, we have assumed and relied with your consent that such
forecasts, including without limitation, financial forecasts, evaluations of
contingencies, Expected Savings and operating synergies resulting from the
Merger and projections regarding underperforming and non-performing assets,
net charge-offs, adequacy of reserves, future economic conditions and results
of operations reflect the best currently available estimates, allocations and
judgments of the senior management of Collective and Summit as to the future
financial performance of Collective, Summit or the combined entity, as the
case may be. Our opinion is predicated on the Merger receiving the tax and
accounting treatment contemplated in the Agreement. Our opinion is necessarily
based on economic, market and other conditions as in effect on, and the
information made available to us as of, the date hereof.     
 
  Our opinion was rendered without regard to the necessity for, or level of,
any restrictions, obligations, undertakings or divestitures which may be
imposed or required in the course of obtaining regulatory approval for the
Merger.
 
  We have been retained by the Board of Directors of Collective as an
independent contractor to act as financial advisor to Collective with respect
to the Merger and will receive a fee for our services. In addition,

Collective has agreed to indemnify us for certain liabilities arising out of
our engagement. We have in the past two years provided financial advisory,
investment banking and other services to Collective and Summit and received
customary fees for the rendering of such services. In addition, in the
ordinary course of our securities business, we may actively trade debt and/or
equity securities of Collective and Summit and their respective affiliates for
our own account and the accounts of our customers, and we therefore may from
time to time hold a long or short position in such securities.
 
  Our opinion is directed to the Board of Directors of Collective and does not
constitute a recommendation to any shareholder of Collective as to how such
shareholder should vote at any shareholder meeting of Collective held in
connection with the Merger. This opinion is directed only to the proposed
Exchange Ratio.
 
  On the basis of, and subject to the foregoing, we are of the opinion that
the proposed Exchange Ratio in the Merger is fair to the shareholders of
Collective from a financial point of view.
 
                                          Very truly yours,

                COLLECTIVE BANCORP, INC. STOCK OPTION AGREEMENT
 
  THE TRANSFER OF THE OPTION GRANTED BY THIS AGREEMENT IS SUBJECT TO RESALE
RESTRICTIONS ARISING UNDER THE SECURITIES ACT OF 1933, AS AMENDED.
 
  STOCK OPTION AGREEMENT, dated as of the 28th day of February, 1997 (this
"Agreement"), between Summit Bancorp., a New Jersey corporation ("Grantee"),
and Collective Bancorp, Inc., a Delaware corporation ("Issuer").
 
                             W I T N E S S E T H :
 
  WHEREAS, Grantee and Issuer have on a date prior to the date hereof, entered
into an Agreement and Plan of Merger, dated as of the 27th day of February,
1997 (the "Merger Agreement"). (Capitalized terms used in this Agreement and
not defined herein but defined in the Merger Agreement shall have the meanings
assigned thereto in the Merger Agreement); and
 
  WHEREAS, as a condition and inducement to Grantee's entering into the Merger
Agreement and in consideration therefor, Grantee has required that Issuer
agree, and Issuer has agreed, to grant Grantee the Option (as defined below);
 
  NOW, THEREFORE, in consideration of the foregoing and the mutual covenants
and agreements set forth herein and in the Merger Agreement, the parties
hereto agree as follows:
 
  SECTION 1. Grant of Option. Issuer hereby grants to Grantee an
unconditional, irrevocable option (the "Option") to purchase, subject to the
terms hereof, up to 4,067,424 fully paid and nonassessable shares of the
common stock, par value $.01 per share, of Issuer ("Common Stock") at a price
equal to $38.125 (such price, as adjusted as hereinafter provided, the "Option
Price"). The number of shares of Common Stock that may be received upon the
exercise of the Option and the Option Price are subject to adjustment as
herein set forth. In no event shall the number of shares of Common Stock for
which this Option is exercisable exceed 19.9% of the number of shares of
Common Stock then issued and outstanding (without consideration of any shares
of Common Stock subject to or issued pursuant to the Option).
 
  SECTION 2. Exercise of Option. (a) Grantee may exercise the Option, in whole
or part, at any time and from time to time following the occurrence of a
Purchase Event (as defined below); provided that the Option shall terminate
and be of no further force and effect upon the earliest to occur of (i) the
time immediately prior to the Effective Time, (ii) the termination of the
Merger Agreement in accordance with the terms thereof prior to the occurrence
of an Extension Event, other than a termination of the Merger Agreement by the
Grantee pursuant to Section 9.02(a)(ii) thereof, or (iii) 15 months after the
termination of the Merger Agreement following the occurrence of an Extension
Event (as defined below), or the termination of the Merger Agreement by
Grantee pursuant to Section 9.02(a)(ii) thereof, and provided further, that
any purchase of Common Stock upon exercise of the Option shall be subject to
applicable law, and provided further, that the Option may not be exercised,
nor may Grantee require Issuer to repurchase the Option (as set forth in
Section 7 hereof), if, at the time of exercise or repurchase, Grantee is in
material breach of any material covenant or obligation contained in the Merger
Agreement and, if the Merger Agreement has not terminated prior thereto, such
breach would entitle Issuer to terminate the Merger Agreement. The events
described in clauses (i) - (iii) in the preceding sentence are hereinafter
collectively referred to as Exercise Termination Events. As provided in
Section 8, the rights set forth therein shall terminate upon an Exercise
Termination Event and, as provided in Sections 6 and 7 hereof, the rights to
deliver requests pursuant to Sections 6 or 7 shall terminate 12 months after
an Exercise Termination Event, subject, in such case, to the provisions of
Section 9.
 
  (b) The term "Extension Event" shall mean any of the following events or
transactions occurring without the Grantee's prior written consent after the
date hereof:
 
    (i) Issuer or any of its subsidiaries (each an "Issuer Subsidiary"),
  shall have entered into an agreement to engage in an Acquisition
  Transaction (as defined below) with any person (the term "person" for
 
                                      C-1
<PAGE>
 
  purposes of this Agreement having the meaning assigned thereto in Sections
  3(a)(9) and 13(d)(3) of the Securities Exchange Act of 1934, as amended
  (the "Securities Exchange Act"), and the rules and regulations thereunder)
  other than Grantee or any of its subsidiaries (each a "Grantee Subsidiary")
  or the Board of Directors of Issuer shall have recommended that the
  shareholders of Issuer approve or accept any Acquisition Transaction with
  any person other than Grantee or any Grantee Subsidiary. For purposes of
  this Agreement, "Acquisition Transaction" shall mean (w) a merger or
  consolidation, or any similar transaction, involving Issuer or any of
  Issuer's banking subsidiaries ("Bank Subsidiaries"), (x) a purchase, lease
  or other acquisition of 10% or more of the aggregate value of the assets or
  deposits of Issuer or any Bank Subsidiary, (y) a purchase or other
  acquisition (including by way of merger, consolidation, share exchange or
  otherwise) of securities representing 10% or more of the voting power of
  Issuer or a Bank Subsidiary, or (z) any substantially similar transaction,
  provided, however, that in no event shall (i) any merger, consolidation or
  similar transaction involving Issuer or any Bank Subsidiary in which the
  voting securities of Issuer outstanding immediately prior thereto continue
  to represent (either by remaining outstanding or being converted into
  voting securities of the surviving entity of any such transaction) at least
  75% of the combined voting power of the voting securities of the Issuer or
  the surviving entity outstanding after the consummation of such merger,
  consolidation, or similar transaction, or (ii) any internal merger or
  consolidation involving only Issuer and/or Issuer Subsidiaries, be deemed
  to be an Acquisition Transaction, provided that any such transaction is not
  entered into in violation of the terms of the Merger Agreement;
 
    (ii) Any person (other than Grantee or any Grantee Subsidiary) shall have
  acquired beneficial ownership or the right to acquire beneficial ownership
  of securities representing 10% or more of the aggregate voting power of
  Issuer or any Bank Subsidiary (the term "beneficial ownership" for purposes
  of this Agreement having the meaning assigned thereto in Section 13(d) of
  the Securities Exchange Act, and the rules and regulations thereunder);
 
    (iii) Any person other than Grantee or any Grantee Subsidiary shall have
  made a bona fide proposal to Issuer or its shareholders, by public
  announcement or written communication that is or becomes the subject of
  public disclosure, to engage in an Acquisition Transaction (including,
  without limitation, any situation in which any person other than Grantee or
  any Grantee Subsidiary shall have 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 of 1933, as amended (the "Securities
  Act"), with respect to, a tender offer or exchange offer to purchase any
  shares of Common Stock such that, upon consummation of such offer, such
  person would own or control securities representing 10% or more of the
  aggregate voting power of Issuer or any Bank Subsidiary);
 
    (iv) After any person other than Grantee or any Grantee Subsidiary has
  made or disclosed an intention to make a proposal to Issuer or its
  shareholders to engage in an Acquisition Transaction, Issuer shall have
  breached any covenant or obligation contained in the Merger Agreement and
  such breach (x) would entitle Grantee to terminate the Merger Agreement and
  (y) shall not have been cured prior to the Notice Date (as defined below);
 
    (v) Any person other than Grantee or any Grantee Subsidiary shall have
  filed an application with, or given a notice to, whether in draft or final
  form, the Board of Governors of the Federal Reserve System (the "Federal
  Reserve Board") or other governmental authority or regulatory or
  administrative agency or commission, domestic or foreign (each, a
  "Governmental Authority"), for approval to engage in an Acquisition
  Transaction; or
 
    (vi) the holders of Common Stock shall not have approved the Merger
  Agreement at the meeting of such shareholders held for the purpose of
  voting on the Merger Agreement, such meeting shall not have been called by
  the Board of Directors of Issuer in accordance with Section 4.03 of the
  Merger Agreement or held or shall have been canceled prior to termination
  of the Merger Agreement or Issuer's Board of Directors shall have withdrawn
  or modified in a manner adverse to the consummation of the Merger the
  recommendation of Issuer's Board of Directors with respect to the Merger
  Agreement, in each case after an Extension Event;
 
 
                                      C-2
<PAGE>
 
    (vii) any Purchase Event (as defined below).
 
  (c) The term "Purchase Event" shall mean either of the following events or
transactions occurring after the date hereof:
 
    (i) The acquisition by any person other than Grantee or any Grantee
  Subsidiary of beneficial ownership of securities representing 25% or more
  of the aggregate voting power of Issuer or any Bank Subsidiary; or
 
    (ii) The occurrence of an Extension Event described in Section 2(b)(i)
  except that the percentage referred to in clauses (x) and (y) shall be 25%.
 
  (d) Issuer shall notify Grantee promptly in writing of the occurrence of any
Extension Event or Purchase Event; provided however, that the giving of such
notice by Issuer shall not be a condition to the right of Grantee to exercise
the Option.
 
  (e) In the event that Grantee is entitled to and 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
shares of Common Stock it will purchase pursuant to such exercise, (ii) a
place and date not earlier than three business days nor later than 90 business
days from the Notice Date for the closing of such purchase (the "Closing
Date") and (iii) that the proposed exercise of the Option shall be revocable
by Grantee in the event that the transaction constituting a Purchase Event
that gives rise to such written notice shall not have been consummated prior
to exercise of the Option; provided that if prior notification to or approval
of the Federal Reserve Board or any other Governmental Authority is required
in connection with such purchase, Grantee shall promptly file the required
notice or application for approval and shall expeditiously process the same
and the period of time that otherwise would run pursuant to this sentence
shall run from the later of (x) the date on which any required notification
periods have expired or been terminated and (y) the date on which such
approvals have been obtained and any requisite waiting period or periods shall
have expired. For purposes of Section 2(a), any exercise of the Option shall
be deemed to occur on the Notice Date relating thereto. Grantee shall have the
right to revoke its proposed exercise of the Option in the event that the
transaction constituting a Purchase Event that gives rise to such right to
exercise shall not have been consummated prior to exercise of the Option,
pursuant to the statement of such right in the written notice exercising the
Option as provided in clause 2(e)(iii) above.
 
  (f) At the closing referred to in Section 2(e), Grantee shall surrender this
Agreement (and the Option granted hereby) to Issuer and pay to Issuer the
Option Price for the shares of Common Stock purchased pursuant to the exercise
of the Option in immediately available funds by wire transfer to a bank
account designated by Issuer; provided, however, that failure or refusal of
Issuer to designate such a bank account shall not preclude Grantee from
exercising the Option.
 
  (g) At such closing, simultaneously with the delivery of the Option Price in
immediately available funds as provided in Section 2(f), Issuer shall deliver
to Grantee a certificate or certificates representing the number of shares of
Common Stock purchased by Grantee and, if the Option should be exercised in
part only, a new Option Agreement granting a new Option evidencing the rights
of Grantee thereof to purchase the balance of the shares of Common Stock
purchasable hereunder.
 
  (h) Certificates for Common Stock delivered at a closing hereunder shall be
endorsed with a restrictive legend substantially as follows:
 
  "The transfer of the shares represented by this certificate is subject
  to resale restrictions arising under the Securities Act of 1933, as
  amended, and to certain provisions of an agreement between Summit
  Bancorp. and Collective Bancorp, Inc. ("Issuer") dated as of the 27thJ
  day of February, 1997. A copy of such agreement is on file at the
  principal office of Issuer and will be provided to the holder hereof
  without charge upon receipt by Issuer of a written request therefor."
 
It is understood and agreed that: (i) the reference to the resale restrictions
of the Securities Act in the above legend shall be removed by delivery of
substitute certificate(s) without such reference if Grantee shall have
delivered to Issuer a copy of a letter from the staff of the Securities and
Exchange Commission (the "SEC"), or
 
                                      C-3
<PAGE>
 
an opinion of counsel, in form and substance satisfactory to Issuer, to the
effect that such legend is not required for purposes of the Securities Act;
(ii) the reference to the provisions of this Agreement in the above legend
shall be removed by delivery of substitute certificate(s) without such
reference if the shares have been sold or transferred in compliance with the
provisions of this Agreement and under circumstances that do not require the
retention of such reference; and (iii) the legend shall be removed in its
entirety if the conditions in the preceding clauses (i) and (ii) are both
satisfied. In addition, such certificates shall bear any other legend as may
be required by law.
 
  (i) Upon the giving by Grantee to Issuer of the written notice of exercise
of the Option provided for in Section 2(e) and the tender of the Option Price
on the Closing Date in immediately available funds, Grantee shall be deemed to
be the holder of record of the shares of Common Stock issuable upon such
exercise, notwithstanding that the stock transfer books of Issuer shall then
be closed or that certificates representing such shares of Common Stock shall
not then actually be delivered to Grantee. Issuer shall pay all expenses and
any and all United States federal, state and local taxes and other charges
that may be payable in connection with the preparation, issue and delivery of
stock certificates under this Section 2 in the name of Grantee or its nominee.
 
  SECTION 3. Reservation of Shares. Issuer agrees: (i) that it shall at all
times until the termination of this Agreement have reserved for issuance upon
the exercise of the Option that number of authorized shares of Common Stock
equal to the maximum number of shares of Common Stock at any time and from
time to time issuable hereunder, all of which shares will, upon issuance
pursuant hereto, be duly authorized, validly issued, fully paid,
nonassessable, and delivered free and clear of all claims, liens, encumbrances
and security interests and not subject to any preemptive rights; (ii) that it
will not, by amendment of its certificate of incorporation or through
reorganization, consolidation, merger, dissolution or sale of assets, or by
any other voluntary act, avoid or seek to avoid the observance or performance
of any of the covenants, stipulations or conditions to be observed or
performed hereunder by Issuer; (iii) promptly to take all action as may from
time to time be required (including (x) complying with all premerger
notification, reporting and waiting period requirements specified in 15 U.S.C.
(S) 18a and regulations promulgated thereunder and (y) in the event, under the
Bank Holding Company Act of 1956, as amended (the "BHC Act"), or the Change in
Bank Control Act of 1978, as amended, or any state banking law, prior approval
of or notice to the Federal Reserve Board or to any other Governmental
Authority is necessary before the Option may be exercised, cooperating with
Grantee in preparing such applications or notices and providing such
information to the Federal Reserve Board and each other Governmental Authority
as they may require) in order to permit Grantee to exercise the Option and
Issuer duly and effectively to issue shares of Common Stock pursuant hereto;
and (iv) to take all action provided herein to protect the rights of Grantee
against dilution.
 
  SECTION 4. 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, on the same terms and subject to the
same conditions as are set forth herein, in the aggregate the same number of
shares of Common Stock purchasable hereunder. The terms "Agreement" and
"Option" as used herein include any agreements and related options for which
this Agreement (and the Option granted hereby) may be exchanged. Upon receipt
by Issuer of evidence reasonably satisfactory to it of the loss, theft,
destruction or mutilation of this Agreement, and (in the case of loss, theft
or destruction) of reasonably satisfactory indemnification, and upon surrender
and cancellation of this Agreement, if mutilated, Issuer will execute and
deliver a new Agreement of like tenor and date. Any such new Agreement
executed and delivered shall constitute an additional contractual obligation
on the part of Issuer, whether or not the Agreement so lost, stolen, destroyed
or mutilated shall at any time be enforceable by anyone.
 
  SECTION 5. Adjustment upon Change of Capitalization. The number of shares of
Common Stock purchasable upon the exercise of the Option shall be subject to
adjustment from time to time as follows:
 
    (a) Subject to the last sentence of Section 1, in the event of any change
  in the Common Stock by reason of stock dividends, split-ups, mergers,
  recapitalizations, combinations, subdivisions, conversions,
 
                                      C-4
<PAGE>
 
  exchanges of shares or the like, the type and number of shares of Common
  Stock purchasable upon exercise hereof shall be appropriately adjusted and
  proper provision shall be made so that, in the event that any additional
  shares of Common Stock are to be issued or otherwise to become outstanding
  as a result of any such change (other than pursuant to an exercise of the
  Option), the number of shares of Common Stock that remain subject to the
  Option shall be increased so that, after such issuance and together with
  shares of Common Stock previously issued pursuant to the exercise of the
  Option (as adjusted on account of any of the foregoing changes in the
  Common Stock), it equals 19.9% of the number of shares of Common Stock then
  issued and outstanding (without consideration of any shares of Common Stock
  subject to or issued pursuant to the Option).
 
    (b) Whenever the number of shares of Common Stock purchasable upon
  exercise hereof is adjusted as provided in this Section 5, the Option Price
  shall be adjusted by multiplying the Option Price by a fraction, the
  numerator of which shall be equal to the number of shares of Common Stock
  purchasable prior to the adjustment and the denominator of which shall be
  equal to the number of shares of Common Stock purchasable after the
  adjustment. In no event shall the Option Price be adjusted to less than the
  par value of the Common Stock to be issued at such Option Price.
 
    (c) It is intended by the parties hereto that the adjustments provided by
  this Section 5 shall fully preserve the economic benefits of this Agreement
  for Grantee.
 
  SECTION 6. Registration Rights.
 
  (a) Demand Registration Rights. After the occurrence of a Purchase Event
that occurs prior to an Exercise Termination Event, Issuer shall, at the
request of Grantee (whether on its own behalf or on behalf of any subsequent
holder of the Option (or part thereof) delivered prior to an Exercise
Termination Event or at the request of a holder of any of the shares of Common
Stock issued pursuant hereto) delivered no later than 12 months after an
Exercise Termination Event, promptly prepare, file and keep current a shelf
registration statement under the Securities Act covering this Option and any
shares issued and issuable pursuant to the Option (the "Option Shares") and
shall use its best efforts to cause such registration statement to become
effective and remain current and to qualify this Option or any such Option
Shares or other securities for sale under any applicable state securities laws
in order to permit the sale or other disposition of this Option or any Option
Shares in accordance with any plan of disposition requested by Grantee;
provided, however, that Issuer may postpone filing a registration statement
relating to a registration request by Grantee under this Section 6 for a
period of time (not in excess of 90 days) if in its judgment such filing would
require the disclosure of material information that Issuer has a bona fide
business purpose for preserving as confidential. Issuer will use its best
efforts to cause such registration statement first to become effective as soon
as practicable after the filing thereof and then to remain effective for such
period not in excess of 180 days from the day such registration statement
first becomes effective, or such shorter time as may be necessary to effect
such sales or other dispositions. Grantee shall have the right to demand two
such registrations. Grantee shall provide all information reasonably requested
by Issuer for inclusion in any registration statement to be filed hereunder.
In connection with any such registration, Issuer and Grantee shall provide
each other with representations, warranties, and other agreements customarily
given in connection with such registrations. If requested by any Grantee in
connection with such registration, Issuer and Grantee shall become a party to
any underwriting agreement relating to the sale of Option Shares, but only to
the extent of obligating themselves in respect of representations, warranties,
indemnities and other agreements customarily included in such underwriting
agreements. Notwithstanding the foregoing, if Grantee revokes any exercise
notice or fails to exercise any Option with respect to any exercise notice
pursuant to Section 2(e), Issuer shall not be obligated to continue any
registration process with respect to the sale of Option Shares.
 
  (b) Additional Persons With Registration Rights. Upon receiving any request
under this Section 6 from any Grantee, Issuer agrees to send a copy thereof to
any other person known to Issuer to be entitled to registration rights under
this Section 6, in each case by promptly mailing the same, postage prepaid, to
the address of record of the persons entitled to receive such copies.
Notwithstanding anything to the contrary contained herein, in no event shall
Issuer be obligated to effect more than two registrations pursuant to this
Section 6 by reason of the fact that there shall be more than one Grantee as a
result of any assignment or division of this Agreement.
 
                                      C-5

  (c) Expenses. Except where applicable state law prohibits such payments,
Issuer will pay all expenses (including without limitation registration fees,
qualification fees, blue sky fees and expenses (including the fees and
expenses of counsel), legal expenses, including the reasonable fees and
expenses of one counsel to the holders whose Option Shares are being
registered, printing expenses and the costs of special audits or "cold
comfort" letters, expenses of underwriters, excluding discounts and
commissions but including liability insurance if Issuer so desires or the
underwriters so require, and the reasonable fees and expenses of any necessary
special experts) in connection with each registration pursuant to this Section
6 (including the related offerings and sales by holders of Option Shares) and
all other qualifications, notification or exemptions pursuant to Section 6.
 
  (d) Indemnification. In connection with any registration under this Section
6, Issuer hereby indemnifies the Grantee, and each officer, director and
controlling person of Grantee, and each underwriter thereof, including each
person, if any who controls such holder or underwriter within the meaning of
Section 15 of the Securities Act, against all expenses, losses, claims,
damages and liabilities caused by any untrue, or alleged untrue, statement
contained in any registration statement or prospectus or notification or
offering circular (including any amendments or supplements thereto) or any
preliminary prospectus, or caused by any omission, or alleged omission, to
state therein a material fact required to be stated therein or necessary to
make the statements therein not misleading, except insofar as such expenses,
losses, claims, damages or liabilities of such indemnified party are caused by
any untrue statement or alleged untrue statement that was included by Issuer
in any such registration statement or prospectus or notification or offering
circular (including any amendments or supplements thereto) in reliance upon
and in conformity with, information furnished in writing to Issuer by such
indemnified party expressly for use therein, and Issuer and each officer,
director and controlling person of Issuer shall be indemnified by such
Grantee, or by such underwriter, as the case may be, for all such expenses,
losses, claims, damages and liabilities caused by any untrue, or alleged
untrue, statement, that was included by Issuer in any such registration
statement or prospectus or notification or offering circular (including any
amendments or supplements thereto) in reliance upon, and in conformity with,
information furnished in writing to Issuer by such holder or such underwriter,
as the case may be, expressly for such use.
 
  Promptly upon receipt by a party indemnified under this Section 6(d) of
notice of the commencement of any action against such indemnified party in
respect of which indemnity or reimbursement may be sought against any
indemnifying party under this Section 6(d), such indemnified party shall
notify the indemnifying party in writing of the commencement of such action,
but the failure so to notify the indemnifying party shall not relieve it of
any liability which it may otherwise have to any indemnified party under this
Section 6(d). In case notice of commencement of any such action shall be given
to the indemnifying party as above provided, the indemnifying party shall be
entitled to participate in and, to the extent it may wish, jointly with any
other indemnifying party similarly notified, to assume the defense of such
action at its own expense, with counsel chosen by it and reasonably
satisfactory to such indemnified party. The indemnified party shall have the
right to employ separate counsel in any such action and participate in the
defense thereof, but the fees and expenses of such counsel (other than
reasonable costs of investigation) shall be paid by the indemnified party
unless (i) the indemnifying party either agrees to pay the same, (ii) the
indemnifying party fails to assume the defense of such action with counsel
satisfactory to the indemnified party, or (iii) the indemnified party has been
advised by counsel that one or more legal defenses may be available to the
indemnifying party that may be contrary to the interests of the indemnified
party. No indemnifying party shall be liable for the fees and expenses of more
than one separate counsel for all indemnified parties or for any settlement
entered into without its consent, which consent may not be unreasonably
withheld.
 
  If the indemnification provided for in this Section 6(d) is unavailable to a
party otherwise entitled to be indemnified in respect of any expenses, losses,
claims, damages or liabilities referred to herein, then the indemnifying
party, in lieu of indemnifying such party otherwise entitled to be
indemnified, shall contribute to the amount paid or payable by such party to
be indemnified as a result of such expenses, losses, claims, damages or
liabilities in such proportion as is appropriate to reflect the relative fault
of Issuer, the Grantee and the underwriters in connection with the statements
or omissions which resulted in such expenses, losses, claims,
 
                                      C-6
<PAGE>
 
damages or liabilities, as well as any other relevant equitable
considerations. The amount paid or payable by a party as a result of the
expenses, losses, claims, damages and liabilities referred to above shall be
deemed to include any legal or other fees or expenses reasonably incurred by
such party in connection with investigating or defending any action or claim;
provided, however, that in no case shall any Grantee be responsible, in the
aggregate, for any amount in excess of the net offering proceeds attributable
to its Option Shares included in the offering. No person guilty of fraudulent
misrepresentation (within the meaning of Section 11(f) of the Securities Act)
shall be entitled to contribution from any person who was not guilty of such
fraudulent misrepresentation. Any obligation by any Grantee to indemnify shall
be several and not joint with other Grantees.
 
  (e) Miscellaneous Reporting. Issuer shall comply with all reporting
requirements and will do all such other things as may be necessary to permit
the expeditious sale at any time of any Option Shares by the Grantee thereof
in accordance with and to the extent permitted by any rule or regulation
promulgated by the SEC from time to time, including, without limitation, Rule
144A. Issuer shall at its expense provide the Grantee with any information
necessary in connection with the completion and filing of any reports or forms
required to be filed by Grantee under the Securities Act or the Exchange Act,
or required pursuant to any state securities laws or the rules of any stock
exchange.
 
  SECTION 7. Repurchase at the Option of Grantee or Owner. (a) Upon the
occurrence of a Repurchase Event (as defined below), (i) at the request (the
date of such request being the "Request Date") of Grantee, delivered prior to
an Exercise Termination Event, Issuer (or any successor thereto) shall
repurchase the Option from Grantee at a price (the "Option Repurchase Price")
equal to the amount by which (A) the market/offer price (as defined below)
exceeds (B) the Option Price, multiplied by the number of shares for which
this Option may then be exercised and (ii) at the request (the date of such
request being the "Request Date") of the owner of Option Shares from time to
time (the "Owner"), delivered within 12 months of the occurrence of a
Repurchase Event (or such later period as provided in Section 9), Issuer shall
repurchase such number of the Option Shares from the Owner as the Owner shall
designate at a price (the "Option Share Repurchase Price") equal to the
market/offer price multiplied by the number of Option Shares so designated.
The term "market/offer price" shall mean the highest of (i) the price per
share of Common Stock at which a tender offer or exchange offer therefor has
been made after the date hereof and on or prior to the Request Date, (ii) the
price per share of Common Stock paid or to be paid by any third party pursuant
to an agreement with Issuer (whether by way of a merger, consolidation or
otherwise), (iii) the highest last sale price for shares of Common Stock
within the 90-day period ending on the Request Date quoted on the Nasdaq
National Market (as reported by The Wall Street Journal, or, if not reported
thereby, another authoritative source), (iv) in the event of a sale of all or
substantially all of Issuer's assets, 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 independent investment banking firm
selected by Grantee or the Owner, as the case may be, divided by the number of
shares of Common Stock outstanding at the time of such sale. In determining
the market/offer price, the value of consideration other than cash shall be
determined by a nationally-recognized independent investment banking firm
selected by Grantee or the Owner, as the case may be, whose determination
shall be conclusive and binding on all parties.
 
  (b) Grantee or the Owner, as the case may be, may exercise its right to
require Issuer to repurchase the Option and/or any Option Shares pursuant to
this Section 7 by surrendering for such purpose to Issuer, at its principal
office, a copy of this Agreement or certificates for Option Shares, as
applicable, accompanied by a written notice or notices stating that Grantee or
the Owner, as the case may be, elects to require Issuer to repurchase the
Option and/or the Option Shares in accordance with the provisions of this
Section 7. As promptly as practicable, and in any event within the later to
occur of (x) five business days after the surrender of the Option and/or
certificates representing Option Shares and the receipt of such notice or
notices relating thereto and (y) the time that is immediately prior to the
occurrence of a Repurchase Event, Issuer shall deliver or cause to be
delivered to Grantee the Option Repurchase Price or to the Owner the Option
Share Repurchase Price therefor or the portion thereof that Issuer is not then
prohibited from so delivering under applicable law and regulation or as a
consequence of administrative policy.
 
 
                                      C-7
<PAGE>
 
  (c) Issuer hereby undertakes to use its reasonable efforts to obtain all
required regulatory and legal approvals and to file any required notices as
promptly as practicable in order to accomplish any repurchase contemplated by
this Section 7. Nonetheless, to the extent that Issuer is prohibited under
applicable law or regulation, from repurchasing the Option and/or the Option
Shares in full, Issuer shall promptly so notify Grantee and/or the Owner and
thereafter deliver or cause to be delivered, from time to time, to Grantee
and/or the Owner, as appropriate, the portion of the Option Repurchase Price
and the Option Share Repurchase Price, respectively, that it is no longer
prohibited from delivering, within five business days after the date on which
Issuer is no longer so prohibited; provided, however, that if Issuer at any
time after delivery of a notice of repurchase pursuant to Section 7(b) is
prohibited under applicable law or regulation, from delivering to Grantee
and/or the Owner, as appropriate, the Option Repurchase Price or the Option
Share Repurchase Price, respectively, in full or in any substantial part,
Grantee or the Owner, as appropriate, may revoke its notice of repurchase of
the Option or the Option Shares either in whole or in part whereupon, in the
case of a revocation in part, Issuer shall promptly (i) deliver to Grantee
and/or the Owner, as appropriate, that portion of the Option Purchase Price or
the Option Share Repurchase Price that Issuer is not prohibited from
delivering after taking into account any such revocation and (ii) deliver, as
appropriate, either (A) to Grantee, a new Agreement evidencing the right of
Grantee to purchase that number of shares of Common Stock equal to the number
of shares of Common Stock purchasable immediately prior to the delivery of the
notice of repurchase less the number of shares of Common Stock covered by the
portion of the Option repurchased or (B) to the Owner, a certificate for the
number of Option Shares covered by the revocation.
 
  (d) For purposes of this Section 7, a Repurchase Event shall be deemed to
have occurred (i) upon the consummation of any merger, consolidation or
similar transaction involving Issuer or any Bank Subsidiary any purchase,
lease or other acquisition of all or a substantial portion of the assets of
Issuer or any Bank Subsidiary, other than any such transaction which would not
constitute an Acquisition Transaction pursuant to the proviso to Section
2(b)(i) hereof or (ii) upon the acquisition by any person of beneficial
ownership of securities representing 25% or more of the aggregate voting power
of Issuer or any Bank Subsidiary, provided that no such event shall constitute
a Repurchase Event unless an Extension Event shall have occurred prior to an
Exercise Termination Event. The parties hereto agree that Issuer's obligations
to repurchase the Option or Option Shares under this Section 7 shall not
terminate upon the occurrence of an Exercise Termination Event if an Extension
Event shall have occurred prior to the occurrence of an Exercise Termination
Event.
 
  (e) Issuer shall not enter into any agreement with any party (other than
Grantee or a Grantee Subsidiary) for an Acquisition Transaction unless the
other party thereto assumes all the obligations of Issuer pursuant to this
Section 7 in the event that Grantee or the Owner elects, in its sole
discretion, to require such other party to perform such obligations.
 
  SECTION 8. Substitute Option in the Event of Corporate Change. (a) In the
event that prior to an Exercise Termination Event, Issuer shall enter into an
agreement (i) to consolidate or merge with any person, other than Grantee or a
Grantee Subsidiary, and shall not be the continuing or surviving corporation
of such consolidation or merger, (ii) to permit any person, other than Grantee
or a Grantee Subsidiary, to merge into Issuer and Issuer shall be the
continuing or surviving corporation, but, in connection with such merger, the
then outstanding shares of Common Stock shall be changed into or exchanged for
stock or other securities of any other person or cash or any other property or
the then outstanding shares of Common Stock shall after such merger represent
less than 50% of the aggregate voting power 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 a Grantee Subsidiary, then, and in each such
case, the agreement governing such transaction shall make proper provision so
that the Option shall, upon the consummation of 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 (x)
the Acquiring Corporation (as defined below) or (y) any person that controls
the Acquiring Corporation (the Acquiring Corporation and any such controlling
person being hereinafter referred to as the Substitute Option Issuer)
 
  (b) The Substitute Option shall be exercisable for such number of shares of
the Substitute Common Stock (as is hereinafter defined) as is equal to the
market/offer price (as defined in Section 7) multiplied by the number
 
                                      C-8
<PAGE>
 
of shares of the Common Stock for which the Option was theretofore
exercisable, divided by the Average Price (as is 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 Option
Price multiplied by a fraction in which the numerator is the number of shares
of the Common Stock for which the Option was theretofore exercisable and the
denominator is the number of shares of Substitute Common Stock for which the
Substitute Option is exercisable.
 
  (c) The Substitute Option shall otherwise 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, provided further that the terms of the
Substitute Option shall include (by way of example and not limitation)
provisions for the repurchase of the Substitute Option and Substitute Common
Stock by the Substitute Option Issuer on the same terms and conditions as
provided in Section 7.
 
  (d) 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 any substantial part
  of the Issuer's assets (or the assets of Issuer Subsidiaries).
 
    (ii) "Substitute Common Stock" shall mean the common stock issued by the
  Substitute Option Issuer upon exercise of the Substitute Option.
 
    (iii) "Average Price" shall mean the average last sale price of a share
  of the Substitute Common Stock (as reported by The Wall Street Journal or,
  if not reported therein, by another authoritative source) for the one year
  immediately preceding the consolidation, merger or sale in question, but in
  no event higher than the last sale 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 person, as Grantee may elect.
 
  (e) 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 the 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 (e), 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 (e)
over (ii) the value of the Substitute Option after giving effect to the
limitation in the clause (e). This difference in value shall be determined by
a nationally recognized investment banking firm selected by Grantee and the
Substitute Option Issuer.
 
  SECTION 9. Extension of Time for Regulatory Approvals.  Notwithstanding
Sections 2(e), 6, 7 and 11, if Grantee has given the notice referred to in one
or more of such Sections, the exercise of the rights specified in any such
Section shall be extended (a) if the exercise of such rights requires
obtaining regulatory approvals, to the extent necessary to obtain all
regulatory approvals for the exercise of such rights, and (b) to the extent
necessary to avoid liability under Section 16(b) of the Securities Exchange
Act by reason of such exercise; provided that in no event shall any closing
date occur more than 18 months after the related Notice Date, and, if the
closing date shall not have occurred within such period due to the failure to
obtain any required approval by the Federal Reserve Board or any other
Governmental Authority despite the reasonable efforts of Issuer or the
Substitute Option Issuer, as the case may be, to obtain such approvals, the
exercise of the Option shall be deemed to have been rescinded as of the
related Notice Date. In the event (a) Grantee receives official notice that an
approval of the Federal Reserve Board or any other Governmental Authority
required for the purchase and sale of the Option Shares will not be issued or
granted or (b) a closing date has not occurred within 18 months after the
related Notice Date due to the failure to obtain any such required approval,
Grantee shall be entitled to
 
                                      C-9
<PAGE>
 
exercise the Option in connection with the resale of the Option Shares
pursuant to a registration statement as provided in Section 6. Nothing
contained in this Agreement shall restrict Grantee from specifying alternative
exercising of rights pursuant to Sections 2(e), 6, 7 and 11, hereof in the
event that the exercising of any such rights shall not have occurred due to
the failure to obtain any required approval referred to in this Section 9.
 
  SECTION 10. Issuer Warranties. Issuer hereby represents and warrants to
Grantee as follows:
 
  (a) Issuer has the requisite corporate power and authority to execute and
deliver this Agreement and to consummate the transactions contemplated hereby.
The execution and delivery of this Agreement and the consummation of the
transactions contemplated hereby have been duly approved by the Board of
Directors of Issuer and no other corporate proceedings on the part of Issuer
are necessary to authorize this Agreement or to consummate the transactions so
contemplated. This Agreement has been duly executed and delivered by, and
constitutes a valid and binding obligation of, Issuer, enforceable against
Issuer in accordance with its terms, except as enforceability thereof may be
limited by applicable bankruptcy, insolvency, reorganization, moratorium and
other similar laws affecting the enforcement of creditors' rights generally
and except that the availability of the equitable remedy of specific
performance or injunctive relief is subject to the discretion of the court
before which any proceeding may be brought.
 
  (b) Issuer has taken all necessary corporate action to authorize and reserve
and to permit it to issue, and at all times from the date hereof through the
termination of this Agreement in accordance with its terms will have reserved
for issuance upon the exercise of the Option, that number of shares of Common
Stock equal to the maximum number of shares of Common Stock at any time and
from time to time issuable hereunder, and all such shares, upon issuance
pursuant hereto, will be duly authorized, validly issued, fully paid,
nonassessable, and will be delivered free and clear of all claims, liens,
encumbrances and security interests and not subject to any preemptive rights.
 
  (c) Upon receipt of the necessary regulatory approvals as contemplated by
this Agreement, the execution, delivery and performance of this Agreement does
not or will not, and the consummation by Issuer of any of the transactions
contemplated hereby will not, constitute or result in (i) a breach or
violation of, or a default under, its certificate of incorporation or by-laws,
or the comparable governing instruments of any of its subsidiaries, or (ii) a
breach or violation of, or a default under, any agreement, lease, contract,
note, mortgage, indenture, arrangement or other obligation of it or any of its
subsidiaries (with or without the giving of notice, the lapse of time or both)
or under any law, rule, ordinance or regulation or judgment, decree, order,
award or governmental or non-governmental permit or license to which it or any
of its subsidiaries is subject, that would in any case give any other person
the ability to prevent or enjoin Issuer's performance under this Agreement in
any material respect.
 
  SECTION 11. Assignment of Option by Grantee. (a) Neither of the parties
hereto may assign any of its rights or delegate any of its obligations under
this Agreement or the Option created hereunder to any other person without the
express written consent of the other party, except that Grantee may assign
this Agreement to a wholly owned subsidiary of Grantee and Grantee may assign
its rights hereunder in whole or in part after the occurrence of a Purchase
Event; provided, however, that until the date 15 days following the date at
which the Federal Reserve Board approves an application by Grantee under the
BHC Act to acquire the shares of Common Stock subject to the Option, Grantee
may not assign its rights under the Option except in (i) a widely dispersed
public distribution, (ii) a private placement in which no one party acquires
the right to purchase securities representing in excess of 2% of the aggregate
voting power of Issuer, (iii) an assignment to a single party (e.g., a broker
or investment banker) for the purpose of conducting a widely dispersed public
distribution on Grantee's behalf, or (iv) any other manner approved by the
Federal Reserve Board. Grantee will pay any reasonable out-of-pocket costs and
expenses of Issuer in connection with any such assignment. The term "Grantee"
as used in this Agreement shall also be deemed to refer to Grantee's permitted
assigns.
 
  (b) Any assignment of rights of Grantee to any permitted assignee of Grantee
hereunder shall bear the restrictive legend at the beginning thereof
substantially as follows:
 
                                     C-10
<PAGE>
 
  "The transfer of the option represented by this assignment and the
  related option agreement is subject to resale restrictions arising
  under the Securities Act of 1933, as amended and to certain provisions
  of an agreement between Summit Bancorp. and Collective Bancorp, Inc.
  ("Issuer") dated as of the 27th day of February, 1997. A copy of such
  agreement is on file at the principal office of Issuer and will be
  provided to any permitted assignee of the Option without change upon
  receipt by Issuer of a written request therefor."
 
It is understood and agreed that (i) the reference to the resale restrictions
of the Securities Act in the above legend shall be removed by delivery of
substitute assignments without such reference if Grantee shall have delivered
to Issuer a copy of a letter from the staff of the SEC, or an opinion of
counsel, in form and substance satisfactory to Issuer, to the effect that such
legend is not required for purposes of the Securities Act; (ii) the reference
to the provisions of this Agreement in the above legend shall be removed by
delivery of substitute assignments without such reference if the Option has
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 be removed in its entirety if the conditions in the
preceding clauses (i) and (ii) are both satisfied. In addition, such
assignments shall bear any other legend as may be required by law.
 
  SECTION 12. Application for Regulatory Approval. If Grantee is entitled to
exercise the Option and has sent a notice to Issuer pursuant to Section 2(e),
each of Grantee and Issuer will use its reasonable efforts to make all filings
with, and to obtain consents of, all third parties and the Federal Reserve
Board and other Governmental Authorities necessary to the consummation of the
transactions contemplated by this Agreement, including, without limitation,
making application for listing or quotation, as the case may be, of the shares
of Common Stock issuable hereunder on the NASDAQ National Market System and
applying to the Federal Reserve Board under the BHC Act and to state banking
authorities for approval to acquire the shares issuable hereunder.
 
  SECTION 13. Specific Performance. The parties hereto acknowledge that
damages would be an inadequate remedy for a breach of this Agreement by either
party hereto and that the obligations of the parties shall hereto be
enforceable by either party hereto through injunctive or other equitable
relief. Both parties further agree to waive any requirement for the securing
or posting of any bond in connection with the obtaining of any such equitable
relief and that this provision is without prejudice to any other rights that
the parties hereto may have for any failure to perform this Agreement.
 
  SECTION 14. Separability of Provisions. If any term, provision, covenant or
restriction contained in this Agreement is held by a court or a federal or
state regulatory agency of competent jurisdiction to be invalid, void or
unenforceable, the remainder of the terms, provisions and covenants and
restrictions contained in this Agreement shall remain in full force and
effect, and shall in no way be affected, impaired or invalidated. If for any
reason such court or regulatory agency determines that Grantee is not
permitted to acquire, or Issuer is not permitted to repurchase, pursuant to
Section 7, the full number of shares of Common Stock provided in Section 1 (as
adjusted pursuant hereto), it is the express intention of Issuer to allow
Grantee to acquire or to require Issuer to repurchase such lesser number of
shares as may be permissible, without any amendment or modification hereof.
 
  SECTION 15. Notices. All notices, requests, claims, demands and other
communications hereunder shall be deemed to have been duly given when
delivered in person, by cable, telegram, telecopy or telex, or by registered
or certified mail (postage prepaid, return receipt requested) at the
respective addresses of the parties set forth in the Merger Agreement.
 
  SECTION 16. Governing Law. This Agreement shall be governed by and construed
in accordance with the laws of the State of New Jersey.
 
  SECTION 17. Counterparts. This Agreement may be executed in two or more
counterparts, each of which shall be deemed to be an original, but all of
which shall constitute one and the same agreement.
 
 
                                     C-11
<PAGE>
 
  SECTION 18. Expenses. Except as otherwise expressly provided herein, each of
the parties hereto shall bear and pay all costs and expenses incurred by it or
on its behalf in connection with the transactions contemplated hereunder,
including fees and expenses of its own financial consultants, investment
bankers, accountants and counsel.
 
  SECTION 19. Entire Agreement; No Third-Party Beneficiaries. Except as
otherwise expressly provided herein or in the Merger Agreement, this Agreement
contains the entire agreement between the parties with respect to the
transactions contemplated hereunder and supersedes all prior arrangements or
understandings with respect thereof, written or oral. The terms and conditions
of this Agreement shall inure to the benefit of and be binding upon the
parties hereto and their respective successors and permitted assigns. Nothing
in this Agreement, expressed or implied, is intended to confer upon any party,
other than the parties hereto, and their respective successors and assigns,
any rights, remedies, obligations or liabilities under or by reason of this
Agreement, except as expressly provided herein.
 
  SECTION 20. Merger Agreement. Nothing contained in this Agreement shall be
deemed to authorize Issuer or Grantee to breach any provision of the Merger
Agreement.
 
  SECTION 21. Majority in Interest. In the event that any selection or
determination is to be made by Grantee or the Owner hereunder and at the time
of such selection or determination there is more than one Grantee or Owner,
such selection shall be made by a majority in interest of such Grantees or
Owners.
 
  SECTION 22. Further Assurances. In the event of any exercise of the Option
by Grantee, Issuer and such Grantee shall execute and deliver all other
documents and instruments and take all other action that may be reasonably
necessary in order to consummate the transactions provided for by such
exercise.
 
  SECTION 23. No Rights as Shareholder. Except to the extent Grantee exercises
the Option, Grantee shall have no rights to vote or receive dividends or have
any other rights as a shareholder with respect to shares of Common Stock
covered hereby.
 
  SECTION 24. Grantee Representation. The Option and any Option Shares or
other securities acquired by Grantee upon exercise of the Option are not
being, and will not be, as the case may be, acquired with a view to the public
distribution thereof in the United States except as provided for in Sections 6
and 11 hereof and neither the Option nor any Option Shares or other securities
acquired by Grantee upon exercise of the Option will be transferred or
otherwise disposed of by Grantee except in a transaction registered or exempt
from registration under the Securities Act.
 
  IN WITNESS WHEREOF, each of the parties has caused this Stock Option
Agreement to be executed on its behalf by their officers thereunto duly
authorized, all as of the date first above written.

                    INFORMATION NOT REQUIRED IN PROSPECTUS
 
ITEM 20. INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
  With respect to the indemnification of directors and officers, Section 5 of
Article IX of the By-Laws of Summit Bancorp. provide:
 
    Section 5. Indemnification and Insurance (a) Each person who was or is
  made a party or is threatened to be made a party to or is involved in any
  proceeding, by reason of the fact that he or she is or was a corporate
  agent of the Corporation, whether the basis of such proceeding is alleged
  action in an official capacity as a corporate agent or in any other
  capacity while serving as a corporate agent, shall be indemnified and held
  harmless by the Corporation to the fullest extent authorized by the laws of
  the State of new Jersey 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 said law permitted the Corporation to provide prior to such
  amendment), against all expenses and liabilities in connection therewith,
  and such indemnification shall continue as to a person who has ceased to be
  a corporate agent and shall inure to the benefit of such corporate agent's
  heirs, executors, administrators and other legal representatives; provided,
  however, that except as provided in Section 5(c) of this By-Law, the
  Corporation shall indemnify any such person seeking indemnification in
  connection with a proceeding (or part thereof) initiated by such person
  only if such proceeding (or part thereof ) was authorized by the Board of
  Directors. The right to indemnification conferred in this By-Law shall be a
  contract right and shall include the right to be paid by the Corporation
  the expenses incurred in defending any such proceeding in advance of its
  final disposition, such advances to be paid by the Corporation within 20
  days after the receipt by the Corporation of a statement or statements from
  the claimant requesting such advance or advances from time to time;
  provided, however, that the advancement of counsel fees to a claimant other
  than a claimant who is or was a director or Executive Vice President or
  higher ranking officer of the Corporation shall be made only when the Board
  of Directors or the General Counsel of the Corporation determines that
  arrangements for counsel are satisfactory to the Corporation; and provided,
  further, that if the laws of the State of New Jersey so require, the
  payment of such expenses incurred by a corporate agent in such corporate
  agent's capacity as a corporate agent (and not in any other capacity in
  which service was or is rendered by such person while a corporate agent,
  including, without limitation, service to an employee benefit plan) in
  advance of the final disposition of a proceeding shall be made only upon
  delivery to the Corporation of an undertaking by or on behalf of such
  corporate agent to repay all amounts so advanced if it shall ultimately be
  determined that such corporate agent is not entitled to be indemnified
  under this By-Law or otherwise.
 
    (b) To obtain indemnification under this By-Law, a claimant shall submit
  to the Corporation a written request, including therein or therewith such
  documentation and information as is reasonably available to the claimant
  and is reasonably necessary to determine whether and to what extent the
  claimant is entitled to indemnification. Upon written request by a claimant
  for indemnification pursuant to the first sentence of this Section 5(b), a
  determination, if required by applicable law, with respect to the
  claimant's entitlement thereto shall be made as follows: (1) if requested
  by a claimant who is or was a director or Executive Vice President or
  higher ranking officers of this Corporation, by independent counsel (as
  hereinafter defined) in a written opinion to the Board of Directors, a copy
  of which shall be delivered to the claimant; or (2) if the claimant is not
  a person described in Section 5(b)(1), or is such a person and if no
  request is made by such a claimant for a determination by independent
  counsel, (A) by the Board of Directors by a majority vote of a quorum
  consisting of disinterested directors (as hereinafter defined), or (B) if a
  quorum of the Board of Directors consisting of disinterested directors is
  not obtainable or, even if obtainable, such quorum of disinterested
  directors so directs, by independent counsel in a written opinion to the
  Board of Directors, a copy of which shall be delivered to the claimant. In
  the event the determination of entitlement to indemnification is to be made
  by independent counsel at the request of the claimant, the independent
  counsel
 
                                     II-1
<PAGE>
 
     
  shall be selected by the Board of Directors and paid by the Corporation. If
  it is so determined that the claimant is entitled to indemnification,
  payment to the claimant shall be made within 20 days after such
  determination.     
 
    (c) If a claim under Section 5(a) of this By-Law is not paid in full by
  the Corporation within thirty days after a written claim pursuant to
  Section 5(b) of this By-Law has been received by the Corporation, the
  claimant may at anytime thereafter bring suit against the Corporation to
  recover the unpaid amount of the claim and, if successful in whole or in
  part, the claimant shall be entitled to be paid also the expense of
  prosecuting such claim, including attorney's fees. It shall be a defense to
  any such act (other than an action brought to enforce a claim for expenses
  incurred in defending any proceeding in advance of its final disposition
  where the required undertaking, if any is required, has been tendered to
  the Corporation) that the claimant has not met the standard of conduct
  which makes it permissible under the laws of the State of New Jersey for
  the Corporation to indemnify the claimant for the amount claimed, but the
  burden of proving such defense shall be on the Corporation. Neither the
  failure of the Corporation (including its Board of Directors or independent
  counsel) to have made a determination prior to the commencement of such
  action that indemnification of the claimant is proper in the circumstances
  because the claimant has met the applicable standard of conduct set forth
  in the laws of the State of New Jersey, nor an actual determination by the
  Corporation (including its Board of Directors or independent counsel) that
  the claimant has not met such applicable standard of conduct, shall be a
  defense to the action or create a presumption that the claimant has not met
  the applicable standard of conduct.
 
    (d) If a determination shall have been made pursuant to Section 5(b) of
  this By-Law that the claimant is entitled to indemnification, the
  Corporation shall be bound by such determination in any judicial proceeding
  commenced pursuant to Section 5(c) of this By-Law.
 
    (e) The right to indemnification and the payment of expenses incurred in
  defending a proceeding in advance of its final disposition conferred in
  this By-Law shall not be exclusive of any other rights which any person may
  have or hereafter acquire under any statute, provisions of the Certificate
  of Incorporation, By-Laws, agreement, vote of stockholders or disinterested
  directors or otherwise. No repeal or modification of this By-Law shall in
  any way diminish or adversely affect the rights of any corporate agent of
  the Corporation hereunder in respect of any occurrence or matter arising
  prior to any such repeal or modification.
 
    (f) The Corporation may maintain insurance, at its expense, to protect
  itself and any corporate agent of the Corporation or other enterprise
  against any expense or liability, whether or not the Corporation would have
  the power to indemnify such person against such expense or liability under
  the laws of the State of New Jersey.
 
    (g) If any provision or provisions of this By-Law shall be held to be
  invalid, illegal or unenforceable for any reason whatsoever: (1) the
  validity, legality and enforceability of the remaining provisions of this
  By-Law (including, without limitation, each portion of any section of this
  By-Law containing any such provision held to be invalid, illegal or
  unenforceable) shall not in any way be affected or impaired thereby; and
  (2) to the fullest extent possible, the provisions of this By-Law
  (including, without limitation, each such portion of any section of this
  By-Law containing any such provision held to be invalid, illegal or
  unenforceable) shall be construed so as to give effect to the intent
  manifested by the provision held invalid, illegal or unenforceable.
 
    (h) For purposes of this By-Law:
 
      (1) "disinterested director" means a director of the Corporation who
    is not and was not a party to or otherwise involved in the matter in
    respect of which indemnification is sought by the claimant.
 
      (2) "independent counsel" means a law firm, a member of a law firm,
    or an independent practitioner that is experienced in matters of
    corporation law and shall include any person who, under
 
                                     II-2
<PAGE>
 
    the applicable standards of professional conduct then prevailing, would
    not have a conflict of interest in representing either the Corporation
    or the claimant in an action to determine the claimant's rights under
    this By-Law.
 
      (3) "corporate agent" means any person who is or was a director,
    officer, employee or agent of the Corporation or of any constituent
    corporation absorbed by the Corporation in a consolidation or merger
    and any person who is or was a director, officer, trustee, employee or
    agent of any subsidiary of the Corporation or of any other enterprise,
    serving as such at the request of this Corporation, or of any such
    constituent corporation, or the legal representative of any such
    director, officer, trustee, employee or agent;
 
      (4) "other enterprise" means any domestic or foreign corporation,
    other than the Corporation, and any partnership, joint venture, sole
    proprietorship, trust or other enterprise, whether or not for profit,
    served by a corporate agent;
 
      (5) "expenses" means reasonable costs, disbursements and counsel
    fees;
 
      (6) "liabilities" means amounts paid or incurred in satisfaction of
    settlements, judgements, fines and penalties;
 
      (7) "proceeding" means any pending, threatened or completed civil,
    criminal, administrative, legislative, investigative or arbitrative
    action, suit or proceeding, and any appeal therein and any inquiry or
    investigation which could lead to such action, suit or proceeding; and
 
      (8) References to "other enterprises" include employee benefit plans;
    references to "fines" include any excise taxes assessed on a person
    with respect to an employee benefit plan; and references to "serving at
    the request of the indemnifying corporation" include any service as a
    corporate agent which imposes duties on, or involves services by, the
    corporate agent with respect to an employee benefit plan, its
    participants, or beneficiaries; and a person who acted in good faith
    and in a manner the person reasonably believed to be in the interest of
    the participants and beneficiaries of an employee benefit plan shall be
    deemed to have acted in a manner "not opposed to the best interest of
    the corporation."
 
    (i) Any notice, request or other communication required or permitted to
  be given to the Corporation under this By-Law shall be in writing and
  either delivered in person or sent by facsimile, telex, telegram, overnight
  mail or courier service, or certified or registered mail, postage prepaid,
  return receipt requested, to the Secretary of the Corporation and shall be
  effective only upon receipt by the Secretary.
 
    (j) This By-Law shall be implemented and construed to provide any
  corporate agent described above who is found to have acted in good faith
  and in a manner such person reasonably believed to be in or not opposed to
  the best interests of the Corporation the maximum indemnification,
  advancement of expenses, and reimbursement for liabilities and expenses
  allowed by law.
 
  Such provision is consistent with Section 14A:3-5 of the Business
Corporation Act of the State of New Jersey, the state of Summit's
incorporation, which permits the indemnification of officers and directors,
under certain circumstances and subject to specified limitations, against
liability which any officer or director may incur in such capacity.
   
  Article 7 of Summit's Restated Certificate of Incorporation provides that:
       
    Except to the extent prohibited by law, no Director or officer of the
  Corporation shall be personally liable to the Corporation or its
  shareholders for damages for breach of any duty owed to the Corporation or
  its shareholders, provided that a Director or officer shall not be relieved
  from liability for any breach of duty based upon an act or omission (a) in
  breach of such person's duty of loyalty to the Corporation or its
  shareholders, (b) not in good faith or involving a knowing violation of law
  or (c) resulting in receipt by such person of an improper personal benefit.
  Neither the amendment or repeal of this Article 7, nor the     
 
                                     II-3
<PAGE>
 
     
  adoption of any provision of this Restated Certificate of Incorporation
  inconsistent with this Article 7, shall eliminate or reduce the effect of
  this Article 7 in respect of any matter which occurred, or any cause of
  action, suit or claim which but for this Article 7 would have accrued or
  arisen, prior to such amendment, repeal or adoption.     
 
  Summit carries officers' and directors' liability insurance policies which
provide coverage against judgments, settlements and legal costs incurred
because of actual or asserted acts of such officers and directors of Summit
arising out of their duties as such, subject to certain exceptions, including,
but not limited to, damages based upon illegal personal profits or adjudicated
dishonesty of the person seeking indemnification. The policies provide
coverage of $40,000,000 in the aggregate.

ITEM 22. UNDERTAKINGS
 
  (a) The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
registrant's annual report pursuant to Section 3(a) or Section 15(d) of the
Securities Exchange Act of 1934 (and, where applicable, each filing of an
employee benefit plan's annual report pursuant to Section 15(d) of the
Securities Exchange Act of 1934) that is incorporated by reference in the
registration statement shall be deemed to be a new registration statement
relating to the securities offered therein, and the offering of such
securities at that time shall be deemed to be the initial bona fide offering
thereof.
 
  (b) The undersigned registrant hereby undertakes:
 
    (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
    aggregate, represent a fundamental change in the information set forth
    in the 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;
         
      Provided, however, that paragraphs (b)(1)(i) and (b)(1)(ii) of this
      section do not apply if the registration statement is on Form S-3,
      Form S-8 or Form F-3 and the information required to be included in
      a post-effective amendment by those paragraphs is contained in
      periodic reports filed with or furnished to the Commission by the
      registrant pursuant to Section 13 or Section 15(d) of the Securities
      Exchange Act of 1934 that are incorporated by reference 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.
 
  (c) Insofar as indemnification for liabilities arising under the Securities
Act of 1933 may be permitted to directors, officers and controlling persons of
the registrant pursuant to the provisions set forth in response to Item
 
                                     II-5
<PAGE>
 
20 hereof, or otherwise, the registrant has been advised that in the opinion
of the Securities and Exchange Commission such indemnification is against
public policy as expressed in the Act and is, therefore, unenforceable. In the
event that a claim for indemnification against such liabilities (other than
the payment by the registrant of expenses incurred or paid by a director,
officer or controlling person of the registrant in the successful defense of
any action, suit or proceeding) is asserted by such director, officer or
controlling person in connection with the securities being registered, the
registrant will, unless in the opinion of its counsel the matter has been
settled by controlling precedent, submit to a court of appropriate
jurisdiction the question of 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.
 
  (d) The undersigned registrant hereby undertakes to respond to requests for
information that is incorporated by reference into the prospectus pursuant to
Items 4, 10(b), 11 or 13 of this Form, within one business day of receipt of
such request, and to send the incorporated documents by first class mail or
other equally prompt means. This includes information contained in documents
filed subsequent to the effective date of the registration statement through
the date of responding to the request.
 
  (e) The undersigned registrant hereby undertakes to supply by means of a
post-effective amendment all information concerning a transaction, and the
company being acquired involved therein, that was not the subject of and
included in the registration statement when it became effective.

Re:    Registration Statement on Form S-4 of Summit Bancorp. Relating to Shares
       of Summit Bancorp. Common Stock Issuable in Connection with the Merger of
       Collective Bancorp, Inc. with and into Summit Bancorp.


Gentlemen:

This opinion is given in connection with Registration Statement No. 333-26397 on
Form S-4 (the "Registration Statement") filed by Summit Bancorp. (the "Company")
with the Securities and Exchange Commission under the Securities Act of 1933, as
amended, with respect to up to 18,621,562 shares of the Company's Common Stock,
par value $1.20 per share )(the "Common Shares"), to be issued to stockholders
of Collective Bancorp, Inc. ("Collective") in connection with the merger of
Collective with and into the Company (the "Merger") pursuant to an Agreement and
Plan of Merger dated February 27, 1997, as amended by Amendment No. 1 dated May
27, 1997 (the "Merger Agreement").

I have acted as counsel for the Company in connection with the filing of the 
Registration Statement. In so acting, I have made such investigation, including 
the examination of originals or copies, certified or otherwise identified to my 
satisfaction, of such corporate documents and instruments as I have deemed 
relevant and necessary as a basis for the opinion hereinafter set forth. In 
connection therewith I have assumed the genuineness of all signatures and the 
authenticity of all documents submitted to me as originals and the conformity to
original documents of all documents submitted to me as certified or photostatic 
copies. As to questions of fact material to such opinion, I have relied upon 
representations of officers or representatives of the Company.

Based upon the foregoing and assuming that (i) the Merger Agreement is duly 
approved by the requisite vote of the stockholders of Collective and (ii) that 
Certificates of Merger complying with the Merger Agreement and meeting all 
applicable requirements of the New Jersey Business Corporation Act and the 
Delaware General Corporation Law are duly executed and filed in accordance with 
such statutes, I am of the opinion that the Common Shares registered under the 
Registration Statement and to be issued in accordance with the Merger Agreement 
upon the effectiveness of the Merger in exchange for outstanding shares of the 
Common Stock, par value $.01 per share, of Collective will be validly issued, 
fully paid and nonassessable.

I hereby consent to the use of this opinion as an exhibit to the Registration 
Statement. I further consent to any and all references to me in the Proxy 
Statement-Prospectus which is part of said Registration Statement.

Very truly yours,


/s/ Richard F. Ober, Jr.

Ladies and Gentlemen:

        You have requested our opinion with regard to certain federal income tax
consequences of the proposed merger (the "Merger") of Collective Bancorp., Inc.
("Collective") with and into Summit Bancorp. ("Summit").

        In connection with the preparation of our opinion, we have examined and 
have relied upon the following:

        (i) The Agreement and Plan of Merger between Summit and Collective dated
            February 27, 1997, including the schedules and exhibits thereto and 
            the amendment thereto dated May 27, 1997 (the "Merger Agreement");

       (ii) Summit's Registration Statement on Form S-4, including the Proxy
            Statement/Prospectus contained therein, filed with the Securities
            and Exchange Commission on May 2, 1997, as supplemented and amended
            to the date hereof (the "Registration Statement");

      (iii) The representations and undertaking of Summit substantially in the 
            form of Exhibit A hereto;

      (iv)  The representations and undertakings of Collective and certain
            holders of Collective common stock, par value $0.01 per share
            ("Collective Common Stock"), substantially in the forms of Exhibit B
            and Exhibit C hereto; and

      (v)   The Shareholder Rights Plan between Summit (formerly UJB Financial
            Corp.) and First Chicago Trust Company of New York, as Rights Agent,
            dated as of August 16, 1989.

        Our opinion is based solely upon applicable law and the factual 
information and undertakings contained in the above-mentioned documents.  In 
rendering our opinion, we have assumed the accuracy of all information and the 
performance of all undertakings contained in each of such documents.  We also 
have assumed the authenticity of all original documents, the conformity of
<PAGE>

all copies to the original documents, and the genuineness of all signatures. We
have not attempted to verify independently the accuracy of any information in
any such document, and we have assumed that such documents accurately and
completely set forth all material facts relevant to this opinion. All of our
assumptions were made with your consent. If any fact or assumption described
herein or below is incorrect, any or all of the federal income tax consequences
described herein may be inapplicable.

                                    OPINION

        Subject to the foregoing, to the conditions and limitations expressed 
elsewhere herein, and assuming that the Merger is consummated in accordance with
the Merger Agreement, we are of the opinion that for federal income tax 
purposes:

        1.  The Merger will constitute a reorganization within the meaning of 
section 368(a)(1) of the Internal Revenue Code of 1986, as amended to the date 
hereof (the "Code").

        2.  Each stockholder of Collective who exchanges, in the Merger, shares 
of Collective Common Stock solely for shares of Summit common stock, par value 
$1.20 per share ("Summit Common Stock"):

                a) will recognize no gain or loss as a result of the exchange,
                   except with regard to cash received in lieu of a fractional 
                   share, as discussed below (Code section 354(a)(1);


                b) will have an aggregate basis for the shares of Summit Common
                   Stock received (including any fractional share of Summit
                   Common Stock deemed to be received, as described in paragraph
                   3, below) equal to the aggregate adjusted tax basis of the
                   shares of Collective Common Stock surrendered (Code section
                   358(a)(1)); and

                c) will have a holding period for the shares of Summit Common
                   Stock received (including any fractional share of Summit
                   Common Stock deemed to be received, as described in paragraph
                   3, below) which includes the period during which the shares
                   of Collective Common Stock surrendered were held, provided
                   that the shares of Collective Common Stock surrendered were
                   capital assets in the hands of such holder at the time of the
                   Merger (Code section 1223(1)).

            3.     Each stockholder of Collective who receives, in the Merger, 
cash in lieu of a fractional share of Summit Common Stock will be treated as if 
the fractional share had been received in the Merger and then redeemed by 
Summit.  Provided that the shares of Collective Common Stock surrendered were 
capital assets in the hands of such holder at the time of the Merger, the 
receipt of such cash will cause the recipient to recognize capital gain or loss,
equal to the difference between the amount of cash received and the portion of 
such holder's basis in the shares of Summit Common Stock allocable to the 
fractional share (Code sections 1001 and 1222; Rev. Rul. 66-365, 1966-2C.B. 
116; Rev. Proc. 77-41, 1977-2 C.B. 574).

            We express no opinion with regard to: (1) the federal income tax
consequences of the Merger not addressed expressly by this opinion, including
without limitation, (i) the tax consequences, if any, to those stockholders of
Collective who acquired shares of Collective Common Stock pursuant to the
exercise of employee stock options or otherwise as compensation, and (ii) the
tax consequences to special classes of stockholders, if any, including without
limitation, foreign

persons, insurance companies, tax-exempt entities, retirement plans, and dealers
in securities; and (2) federal, state, local, or foreign taxes (or any other 
federal, state, local, or foreign laws) not specifically referred to and 
discussed herein. Further, our opinion is based upon the Code, Treasury 
Regulations proposed or promulgated thereunder, and administrative 
interpretations and judicial precedents relating thereto, all of which are 
subject to change at any time, possibly with retroactive effect, and we assume 
no obligation to advise you of any subsequent change thereto. If there is any 
change in the applicable law or regulations, or if there is any new 
administrative or judicial interpretation of the applicable law or regulations, 
any or all of the federal income tax consequences described herein may become 
inapplicable.

        The foregoing opinion reflects our legal judgment solely on the issues 
presented and discussed herein. This opinion has no official status or binding 
effect of any kind. Accordingly, we cannot assure you that the Internal Revenue 
Service or any court of competent jurisdiction will agree with this opinion.

        We hereby consent to the filing of this letter as an exhibit to the 
Registration Statement and to all references made to this letter and to this 
firm in the Registration Statement.

                                                Very truly yours,
