                              PRIME BANCORP, INC.


Dear Shareholder:                            ______________________, 1999


     You are cordially invited to attend a Special Meeting of Shareholders of
Prime Bancorp, Inc. to be held at ____________________ on ____________, 1999 at
_____ a.m., local time. At this meeting you will be asked to consider and
approve the Agreement and Plan of Merger dated February 17, 1999 (the "Merger
Agreement") between Prime Bancorp, Inc. ("Prime") and Summit Bancorp.
("Summit"). Under the terms of the Merger Agreement, Prime will be merged into
First Valley Corporation ("First Valley"), a wholly owned subsidiary of Summit,
pursuant to and in accordance with the provisions of, and with the effect
provided in, the corporate laws of the Commonwealth of Pennsylvania. First
Valley will be the surviving corporation.


     Under Pennsylvania law, in order to consummate the merger, Prime must hold
a special meeting of shareholders and obtain the approval of a majority of the
shares of Prime common stock voted at the meeting. In addition, the merger is
also subject to the receipt of all required regulatory approvals and other
customary conditions described in the enclosed Proxy Statement-Prospectus.
Approval by the shareholders of Summit is not required.


     Pursuant to the terms of the Merger Agreement, if the merger is approved
and completed, upon the effective date of the merger, shareholders of Prime
will be entitled to receive 0.675 of a share of Summit common stock in exchange
for each share of Prime common stock owned. No fractional shares of Summit
common stock will be issued in connection with the merger and, instead, Summit
will pay Prime shareholders the value of any fractional shares of Summit common
stock in cash. Your rights as a shareholder of Summit will be somewhat
different from those as a shareholder of Prime due in part to the differences
in state laws governing each company and differences in their respective
corporate charters, which are described in the enclosed Proxy Statement-
Prospectus.


     A notice of the Special Meeting of Shareholders, a proxy for your use in
connection with that meeting, and a Proxy Statement-Prospectus describing the
proposed transaction in detail accompany this letter. We urge you to read all
of these documents carefully before deciding on how to vote your shares. We are
also enclosing for your information a copy of Prime's Annual Report on Form
10-K for the year ended December 31, 1998.


     Your Board of Directors has unanimously determined that the merger is fair
to and in the best interests of Prime, its shareholders and other
constituencies. Both management and the Board of Directors of Prime believe
that the combination with Summit, an institution with a strong banking
franchise in geographic areas not currently serviced by Prime Bank, strong
financial resources, and a wide variety of product offerings, including trust
department services, is very positive for Prime shareholders. Accordingly, your
Board of Directors unanimously recommends that you vote "FOR" approval of the
proposed transaction.


     We hope that you will attend the Special Meeting. Regardless of your plans
to attend, we urge you, because of the importance of this matter, to execute
and mail the enclosed proxy in the envelope provided. If you decide to attend
the meeting, you may withdraw your proxy and vote in person on all matters
brought before it.



                                        Sincerely,




                                        James J. Lynch

                             Prime Special Meeting

Time, Date, Place and Purpose (see page ---- )

     Prime will hold a special meeting of its shareholders on -------- , 1999
at ______ (local time), in the ____________________________ . At the meeting
you will vote upon (1) the merger and (2) adjournment of the special meeting,
if necessary to obtain a quorum or to obtain additional votes in favor of the
merger. A copy of the merger agreement is attached as Appendix A.


Record Date, Vote Required (see page ---- )

     You are entitled to vote at the Prime special meeting if you owned shares
of Prime common stock at the close of business on __, 1999. The holders of at
least one-third of the shares of Prime common stock outstanding on ---- , 1999
must be present, in person or by proxy, to constitute a quorum at the special
meeting. Approval of the merger requires the affirmative vote of at least a
majority of the shares of Prime common stock cast at the meeting. If a quorum
is not present or there are not sufficient votes to approve the merger, 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 Prime Board of Directors.


                   Stock Held by Prime Directors and Others

     The directors and executive officers of Prime and certain persons who may
be deemed to be their affiliates beneficially owned, as of February 26, 1999,
2,022,019 shares of Prime common stock (assuming the exercise of all options to
purchase Prime common stock held by such persons and outstanding on such date),
representing 17.78% of the outstanding shares of Prime common stock. Each of
the directors and executive officers of Prime has entered into an agreement
with Summit to vote all of their shares of Prime common stock in favor of the
proposal to approve the merger.

     Summit beneficially owns 106,700 shares of Prime common stock, which
represents less than 1% of the outstanding shares of Prime common stock, and
intends to vote these shares in favor of the proposal to approve the merger and
the proposal to adjourn the special meeting (if necessary). In addition, Prime
has granted Summit a stock option that allows Summit to acquire up to 1,087,498
shares of Prime common stock. This option is not currently exercisable and the
Prime common stock represented by the option has not been issued and cannot
currently be voted.


                                  The Merger

Anticipated Closing Date of the Merger (see page ---- )

     If the merger is approved by the Prime shareholders and all the conditions
to closing are satisfied or waived, we will file articles of merger with the
Commonwealth of Pennsylvania which will specify the date and time at which the
merger will become effective. If the merger is approved by Prime shareholders
and the conditions set forth in the merger agreement are satisfied or waived,
we currently expect that the merger will become effective during the third
calendar quarter of 1999.


Exchange Ratio (see page ---- )

     If the merger is completed, you will be entitled to receive whole shares
of Summit common stock in exchange for your shares of Prime common stock, based
upon an exchange ratio of 0.675 of a share of Summit common stock for each
share of Prime common stock you own, plus cash instead of any fractional share.
On _______, 1999, the closing price of Summit common stock was $_____, making
the value of 0.675 of a share of Summit common stock equal to $ _______.
Because the market price of Summit stock fluctuates, you will not know when you
vote what the shares will be worth when issued in the merger.


                                       2
<PAGE>

Conversion of Prime Stock Options (see page ---- )

     Each Prime stock option outstanding at the effective time of the merger
will be converted automatically into an option to purchase Summit common stock.
The number of shares of Summit common stock subject to the converted options
and the exercise price per share of the new options will be adjusted as
provided in the merger agreement based on the exchange ratio.

Recommendation and Reasons of Prime Board of Directors (see page ---- )

     The Prime Board of Directors unanimously recommends that Prime
shareholders vote to approve the merger and the proposal to adjourn the meeting
if necessary.

     The Prime Board of Directors has concluded that the proposed merger is in
the best interest of Prime, its shareholders, employees and customers, and the
communities which Prime Bank serves. The Prime Board considered a number of
important factors, some of which are listed below:

   o the cost of capital needed for people, technology, facilities and
     acquisitions to increase its market penetration in the eastern
     Pennsylvania markets;

   o Prime Bank's need to expand product offerings to its customers to
     generate other revenue enhancing opportunities;

   o Summit's asset base and financial strength;

   o the value of the consideration offered by Summit and the increase in
     dividend payments to Prime's shareholders resulting from the merger;

   o the premium offered by Summit for Prime's common stock in terms of market
     price and other recognized financial ratios; and,

   o Summit's desire to maintain Prime Bank's management, commercial lending
     personnel and branch network

Opinion of Prime's Financial Advisor (see page ---- and Appendix B)

     In deciding to approve the merger agreement, the Prime Board engaged
Fox-Pitt, Kelton, Inc. to act as financial advisor to Prime and to give its
opinion to the Prime Board as to whether the exchange ratio is fair, from a
financial point of view, to the shareholders of Prime. Fox-Pitt, Kelton has
delivered to the Prime Board an opinion dated as of the date of this Proxy
Statement-Prospectus stating that, as of such date, and subject to the
limitations described in the opinion, the exchange ratio is fair, from a
financial point of view, to Prime's shareholders. If the merger is completed,
Fox-Pitt, Kelton will be paid a fee equal to 0.75% of the aggregate
consideration payable by Summit in the merger for its advice and the fairness
opinion. A copy of Fox-Pitt, Kelton's opinion is attached as Appendix B to this
Proxy Statement-Prospectus and should be read in its entirety.

Dissenters Rights (see page ---- and Appendix D)

     Under Pennsylvania law, you will have the right to dissent from the
merger, in which event you may be entitled to receive the "fair value" of your
shares of Prime common stock by complying with the specific procedures
described in this Proxy Statement-Prospectus. The dissenters rights provisions
of the Pennsylvania laws are attached as Appendix D to this Proxy
Statement-Prospectus.

Federal Income Tax Consequences (see page ---- )

     We have structured the merger so that Prime shareholders will not
recognize any gain or loss for federal income tax purposes in the merger
(except for tax payable because of cash received instead of fractional shares).
We have conditioned the merger on our receipt of a legal opinion that such is
the case.

Accounting Treatment (see page ---- )

     Summit expects to account for the merger under the purchase method of
accounting. Under the purchase method of accounting, the amount by which the
purchase price paid by Summit exceeds the fair value of the net assets acquired
will be treated as goodwill. Intangibles recorded in the transaction will be
amortized over a period not to exceed 20 years.


                                       3
<PAGE>

Regulatory Approvals (see page ---- )


     The acquisition of Prime by Summit must be approved by the Board of
Governors of the Federal Reserve System and the Department of Banking of the
Commonwealth of Pennsylvania.


Conditions to the Merger (see page ---- )


     The following conditions must be met for us to complete the merger:


     o approval of the merger by the Prime shareholders; and


   o approval of the merger by regulatory authorities without burdensome
     demands and the expiration of any waiting period following such approval.


     There are certain other normal and customary conditions to completion of
the merger, including receipt of legal opinions, the New York Stock Exchange's
indication that the shares of Summit Common Stock to be issued in the merger
will be listed on the exchange, and the receipt of the opinion of Thompson
Coburn, special tax counsel to Summit, as to certain federal income tax
consequences of the merger.


     Certain conditions to the merger may be waived by the company for whose
benefit the condition was included. However, the merger will not be completed
without the receipt of required regulatory approvals and Prime shareholder
approval.


Termination of the Merger Agreement (see page ---- )


     We can agree to terminate the merger agreement without completing the
merger and, generally, either of us can terminate the merger agreement if any
of the following occurs:


   o the shareholders of Prime do not approve the merger;


   o the other party materially breaches a warranty, representation or
     covenant and does not cure the breach or the breach cannot be cured within
     30 days of notice; or


    o we do not complete the merger by January 3, 2000.


     Generally, the company seeking to terminate cannot itself be in violation
of the merger agreement so as to allow the other party to terminate. Further,
if the average price of Summit common stock over a ten- day trading period
ending on the date the last bank regulatory approval is received is below
$32.68125 and the stock prices of certain other bank holding companies have not
experienced relative declines greater than 17% compared to the decline of the
Summit stock price since the time the companies agreed to merge, Prime may
terminate the merger agreement. Summit may terminate the merger agreement if
the Prime Board of Directors modifies its recommendation or withdraws its
approval of the merger agreement or if the cost of certain environmental
matters exceeds the threshold set forth in the merger agreement.


Other Interests of Prime Officers and Directors in the Merger (see page ---- )


     In considering the Prime Board's recommendation that you vote in favor of
the merger agreement, you should be aware that some directors and executive
officers of Prime have interests in the merger that are different from, or in
addition to, your interest as a shareholder of Prime. These interests exist
because of certain provisions in the merger agreement and rights that certain
Prime officers have under benefit plans maintained by Prime and separate
agreements with Prime and Summit and include the following:


   o The merger agreement contains indemnification arrangements for officers
     and directors of Prime, and Summit has agreed to purchase directors' and
     officers' liability insurance for a six year period following the merger.


                                       4
<PAGE>

   o Summit has agreed to appoint James J. Lynch, Chairman, President and
     Chief Executive Officer of Prime, as Chairman and Chief Executive Officer
     of Summit Bank (Pennsylvania) at an annual salary and bonus not less than
     he received from Prime during 1998, and Mr. Lynch will be included as a
     participant in Summit's Executive Severance Plan and will enter into a
     Termination Agreement with Summit, under which he will receive severance
     payments if his employment with Summit is terminated under certain
     circumstances.

   o Options to purchase 447,484 shares of Prime common stock held by Prime
     executive officers and directors, including options not currently
     exercisable, will be automatically converted into options to acquire
     shares of Summit common stock, adjusted in accordance with the exchange
     ratio in the merger agreement.

   o James J. Lynch, William H. Bromley and James E. Kelly, executive officers
     of Prime, have agreements with Prime which provide for severance payments
     (based upon their compensation through December 31, 1998) of $1,283,458,
     $520,000, and $344,875, respectively, if their employment is terminated
     under certain circumstances after the merger.

   o Certain members of the Prime Board will likely become members of the
     Summit Bank (Pennsylvania) Board of Directors and will be entitled to
     receive directors' fees.

     The Prime Board recognized these interests and considered them when it
approved the merger agreement.


Difference in Shareholders' Rights (see page ---- )

     The rights of Prime shareholders, which are determined by Pennsylvania
corporation law and the Articles of Incorporation and Bylaws of Prime, differ
from the rights of 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 laws of Pennsylvania, the state of Prime's
incorporation, and the corporation law of New Jersey, the state of Summit's
incorporation. The remaining differences in shareholders' rights are
attributable to differences between the Articles of Incorporation and Bylaws of
Prime and the Restated Certificate of Incorporation and By-Laws of Summit. Upon
completion of the merger your rights will be governed by New Jersey corporation
law and Summit's Restated Certificate of Incorporation and By-laws.


Option Agreement (see page ---- )

     As a condition to its offer to acquire Prime, and in order to increase the
likelihood that the merger will be completed on the terms set forth in the
merger agreement, Summit required Prime to grant Summit a stock option that
allows Summit to buy up to 1,087,498 shares of Prime's common stock at an
exercise price of $18.00 per share, the last sale price on February 17, 1999,
the last full trading day prior to the announcement of the signing of the
merger agreement. In addition, if the stock option becomes exercisable and
Summit exercises the option in full, Prime is required to pay Summit
$5,000,000. Summit can exercise the option only if another person acquires 25%
or more of Prime common stock or Prime agrees to be acquired by another party,
or Prime fails to hold the special meeting of shareholders to approve the
merger or the Prime Board modifies or withdraws its recommendation of the
merger after another person acquires, makes an offer or discloses its intention
to acquire 10% or more of Prime common stock. As of the date of this document,
we do not believe that any of these events has occurred. The option agreement
may be expected to discourage persons who, now or prior to completion of the
merger, may be interested in acquiring Prime from considering or proposing such
an acquisition. A copy of the stock option agreement is attached as Appendix C
to this Proxy Statement--Prospectus.

      Summary of Comparative and Pro Forma Per Share Financial Information

     The following summary presents, for the periods and at the dates
indicated, selected comparative and pro forma per share financial information:
(i) on an historical basis for both Summit and Prime; (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 Prime. Such financial information
is computed on a pro forma equivalent basis with respect to a share of Prime
common stock by multiplying the pro forma combined amount (giving effect to the
merger) by the exchange ratio of 0.675. The pro forma information does not
reflect anticipated cost savings expected to be realized from the merger. The
purchase accounting adjustments used for the purpose of calculating the pro
forma combined results are subject to final determination, based upon estimates
and other evaluations of fair value, as of the close of the transaction.
Therefore, the pro forma amounts reflected in the pro forma per share financial
information may differ from the amounts ultimately determined. The unaudited
pro forma information does not purport to be indicative of the combined
financial position or results of operations of future periods.

                                 INTRODUCTION

     We are providing this Proxy Statement-Prospectus to shareholders of Prime
Bancorp, Inc., a Pennsylvania corporation and registered bank holding company,
("Prime") as of       , 1999 (the "Record Date") in connection with the
solicitation of proxies by the Board of Directors of Prime (the "Prime Board")
for use at the Special Meeting of Shareholders of Prime to be held on         ,
1999 at the          , Pennsylvania at 10:00a.m., local time or any
adjournments thereof ("Special Meeting"). At the Special Meeting the
shareholders of Prime will vote upon (i) a proposal to approve the Agreement
and Plan of Merger dated February 17, 1999 ("Merger Agreement") between Summit
Bancorp., a New Jersey corporation and registered bank holding company
("Summit"), and Prime and the transactions contemplated thereby, and (ii) a
proposal to approve in advance of voting on the Merger Agreement an adjournment
of the Special Meeting in order to permit further solicitation of proxies by
Prime if insufficient shares are present at the Special Meeting to constitute a
quorum or to approve the Merger Agreement (the "Adjournment Proposal").
Shareholders of Prime are entitled to exercise dissenters rights with respect
to the Merger Agreement. See "THE MERGER -- Dissenters Rights."

     The Prime Board has unanimously approved the Merger Agreement and
unanimously recommends that Prime shareholders vote FOR its approval. The Board
of Directors of Prime also unanimously recommends that Prime shareholders vote
FOR approval of the Adjournment Proposal.


                                SPECIAL MEETING


Record Date

     Holders of record of Prime common stock, par value $1.00 per share ("Prime
Common") as of the close of business on the Record Date are entitled to vote at
the Special Meeting, with each share of Prime Common entitling its owner to one
vote on each proposal and on all other matters properly brought before the
Special Meeting. Prime had no other class of outstanding voting securities
entitled to vote on the Merger Agreement or the Adjournment Proposal at the
close of business on the Record Date. As of the record date there were
approximately 900 holders of record of Prime Common and        shares of Prime
Common outstanding and eligible to be voted at the Special Meeting. We
anticipate that this Proxy Statement-Prospectus, together with the enclosed
proxy card, will be mailed to shareholders on or about      , 1999.


Quorum and Vote Required

     The presence at the Special Meeting, in person or by proxy, of the holders
of at least one-third of the shares of Prime 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 Prime Board, a shareholder
may vote "FOR" approval of the Merger Agreement, vote "AGAINST" approval of the
Merger Agreement or "ABSTAIN" from voting. Under the Pennsylvania Business
Corporation Law (the "PBCL") and Prime's Articles of Incorporation, the
approval of the Merger Agreement and the approval of the Adjournment Proposal
each require the affirmative vote of the majority of the votes cast at the
Special Meeting. Under Prime's Articles of Incorporation, the approval of the
Merger Agreement requires only the affirmative vote of a majority of the votes
cast because the Merger Agreement has been approved by a majority of the
members of the Prime Board. Therefore, the higher shareholder approval
requirements for certain business combinations which have not been approved by
the Prime Board, or which do not satisfy other conditions set forth in the
Prime Articles of Incorporation, are not applicable to the Merger.


Voting and Revocation of Proxies

     As noted above, adoption of each proposal requires the affirmative vote of
a majority of the votes cast at the Special Meeting. For purposes of
determining the votes cast with respect to either of the two proposals, only
those cast "FOR" or "AGAINST" are included. Accordingly, abstentions and
"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 rule) will
be treated as shares that are present and entitled to vote for purposes of
determining the presence of a quorum, but as not voted on the particular
proposal and therefore


                                       8
<PAGE>

will have no effect on the approval of the Merger Agreement or the Adjournment
Proposal. Proxies voting against the Merger Agreement will not be used by the
proxy holders to vote in favor of the Adjournment Proposal unless the
shareholder has voted FOR approval of the Adjournment Proposal on the proxy
card. The Special Meeting may be adjourned from time to time if necessary to
obtain a quorum or to obtain the votes necessary to approve the Merger
Agreement. The approval of the Merger Agreement by Prime shareholders is a
condition to the consummation of the Merger. See "THE MERGER--The Merger
Agreement--Conditions to the Merger; Termination."

     If a quorum is not present, or if the number of shares of Prime Common
voting by proxy in favor of approval of the Merger Agreement is fewer than the
number required for approval, it is expected that, if a majority of the shares
voted, in person or by proxy, with respect to the Adjournment Proposal have
been voted in favor of the Adjournment Proposal, the Special Meeting will be
postponed or adjourned for the purpose of allowing additional time for
obtaining additional proxies or votes, and, 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 effectively been revoked or withdrawn). As
to other matters that may properly come before the Special Meeting, unless
otherwise provided in the Articles of Incorporation or Bylaws of Prime or by
statute, the matter will be approved if a majority of the votes cast are in
favor of the matter.

     If the enclosed form of proxy is properly executed and returned to Prime
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
approval of the Merger Agreement and FOR 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 in favor of the Adjournment Proposal but will be treated as an
abstention. Should any other matter properly come before the Special Meeting,
including but not limited to matters incidental to the conduct of the meeting,
the persons named as proxies in the accompanying proxy, acting by a plurality
of those proxies present, will have, and intend to use, discretionary authority
to vote on such matters in accordance with their reasonable business judgment.
As of the time of the preparation of this Proxy Statement-Prospectus, the Prime
Board does not know of any matters other than those referred to in the Notice
of Special Meeting of Shareholders to be presented for action at the Special
Meeting.

     Shareholders who execute a proxy retain the right to revoke it at any time
prior to its use. Unless the proxy is revoked in a timely manner, the shares
represented by that proxy will be voted at the Special Meeting and all
adjournments 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 Prime, Joseph A. Fluehr, III. 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 Prime prior to the vote being taken.
The giving of a proxy does not prevent a shareholder from voting in person
should the shareholder so desire. However, in order to vote in person after
having submitted a written proxy, the shareholder must notify the Secretary of
Prime in writing prior to the vote being taken at the Special Meeting that the
shareholder desires to revoke the proxy and vote in person. Revocation of a
proxy shall not affect any vote taken prior to revocation of the proxy.

     If a Prime shareholder is participating in Prime's Dividend Reinvestment
Plan (the "Prime Dividend Plan"), the shareholder will receive a single proxy
covering both the shares of Prime Common held by the Prime shareholder in
certificate form and the shares of Prime Common held on behalf of the
shareholder by the Prime Dividend Plan Administrator in the shareholder's Prime
Dividend Plan account. If a proxy is not returned, shares of Prime Common
represented by the proxy, including any held under the Prime Dividend Plan,
will not be voted.

     Employees who hold Prime Common through participation in Prime's
Retirement Savings Plan ("Prime Savings Plan") will receive a separate card for
use in providing voting instructions to the Trustee of the Prime Savings Plan.
Full shares held by the Prime Savings Plan will be voted by the Trustee in
accordance with the instructions received from the participants.

     If a person holding Prime Common in street name wishes to vote such Prime
Common at the Special Meeting, the person must obtain from the nominee holding
the Prime Common in street name a properly executed "legal proxy" identifying
the individual as a Prime shareholder, authorizing the Prime shareholder to act
on behalf of the shareholder of record 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 Prime. In addition to use
of the mails, proxies may be solicited personally or by telephone, telecopier
or telegraph by officers, directors or employees of Prime, who will not be
specially compensated for such solicitation activities. Arrangements will also
be made by Prime 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. Prime has retained Georgeson & Co., a proxy soliciting firm, to
assist in the solicitation of proxies, at a fee of $7,500 plus fees for direct
telephone solicitations, if authorized, and reimbursement of certain
out-of-pocket costs. Expenses incurred for the printing and mailing of this
Proxy Statement--Prospectus and related filing fees will be paid by Summit.

     On April 14, 1999 Summit's Board of Directors approved an increase in the
quarterly cash dividend paid on Summit Common to $0.33 per share. The increased
dividend will be first paid on August 2, 1999 to shareholders of record as of
July 8, 1999.

     On February 17, 1999, the last full trading day prior to the public
announcement of the execution of the Merger Agreement, the last sale price of a
share of Summit Common was $39.38 and the last sale price of a share of Prime
Common was $18.00. On ___, 1999, the last sale price of Summit Common was $____
and the last sale price of Prime Common was $______. Prime shareholders are
urged to obtain current market quotations.

     On the date the merger is consummated and the date Summit stock
certificates are received by Prime shareholders entitled thereto, the price of
a share of Summit Common may differ from those set forth above. Prime
shareholders should obtain current price quotations. In addition, past
dividends paid on Summit Common and Prime Common are not necessarily indicative
of future dividends which may be paid. No assurance can be given concerning
dividends to be declared and paid on Summit Common and Prime Common before or
after the merger.

Coordination and Determination of Dividends Under Merger Agreement

     In order to ensure that Prime shareholders would be paid no more than one
regular dividend in the calendar quarter in which the merger is consummated,
Prime 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, Prime may declare a quarterly dividend up to $.11 per share of Prime
Common in each quarter in which the Prime shareholders are not otherwise
entitled to a Summit dividend on the shares of Summit Common received in the
merger and if the merger has not been completed by November 30, 1999 Prime may
increase the amount of its quarterly dividend to $.13 per share.

Dividend Limitations

     Summit's primary source of funds to pay dividends to its shareholders is
provided by dividends from its subsidiary banks. The bank subsidiaries of
Summit are restricted by law in the amount of dividends they may pay to Summit.
In addition, Summit is restricted by certain debt agreements in the amount of
dividends it may pay to its shareholders. At March 31, 1999, the subsidiary
banks had approximately $81.9 million available, under the most restrictive
limitations, for the payment of dividends to Summit.

     Similarly, Prime's primary source of funds to pay dividends to its
shareholders is provided by dividends from Prime Bank, which is restricted by
law in the amount of dividends that it may declare and pay to Prime.


                PROPOSAL I -- APPROVAL OF THE MERGER AGREEMENT

                                  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 the Merger Agreement is attached
hereto as Appendix A and is incorporated herein by reference.


General

     The Merger Agreement provides for the acquisition of Prime by Summit,
pursuant to the merger of Prime with and into Summit or a wholly owned
subsidiary of Summit or the merger of a wholly owned subsidiary of Summit with
and into Prime, as determined by Summit. Summit has determined to merge Prime
with and into First Valley Corporation ("First Valley"), a Pennsylvania
corporation and wholly owned subsidiary of Summit, with First Valley as the
surviving corporation in the Merger (the "Merger").

     Upon consummation of the Merger, each outstanding share of Prime Common
other than (i) shares of Prime Common beneficially owned by Summit or a
subsidiary of Summit (other than shares held in a fiduciary capacity or as a
result of foreclosures or debts previously contracted), if any, (ii) shares of
Prime Common beneficially owned by Prime or a subsidiary of Prime (other than
shares of Prime Common held in a fiduciary capacity or as a result of
forfeitures or debts previously contracted), if any, and (iii) shares of Prime
Common held in the treasury of Prime, if any, will be converted into and
represent the right to receive whole shares of Summit Common and cash in lieu
of fractional shares resulting from the conversion (the "Cash In Lieu Amount")
based upon an exchange ratio of 0.675 of a share of Summit Common for each
share of Prime Common (the "Exchange Ratio"), adjusted if necessary in
accordance with certain anti-dilution provisions described below (whole shares
of Summit Common and any Cash In Lieu Amount determined in accordance with the
Exchange Ratio are referred to collectively herein as the "Merger
Consideration"). The Cash in Lieu Amount will be equal to the fraction of a
whole share represented by the fractional share multiplied by the closing price
of a share of Summit Common on the NYSE Composite Transactions List on the last
trading day ending prior to the effective time of the Merger. The Exchange
Ratio is subject to appropriate adjustments in the event that, from the date of
the Merger Agreement to the effective time of the Merger, 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 merger,
recapitalization, reclassification, stock dividend, stock split or reverse
stock split or other similar changes.


Closing and Effective Time

     The Merger Agreement provides that, unless an earlier date designated by
Summit on at least five business days notice ("Closing Notice") is given to
Prime, the closing of the Merger ("Closing") will be held 45 business days
after the last to occur of the following (the "Scheduled Date"): (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 judgement of Summit and Prime, to the consummation
of the transactions contemplated by the Merger Agreement or such prior date as
Summit and Prime shall elect, whether or not such proceedings have been brought
to a conclusion; or (2) the date on which the approvals (collectively the
"Required Approvals") of the shareholders of Prime, the Board of Governors of
the Federal Reserve System ("Federal Reserve Board") and the Banking Department
of the Commonwealth of Pennsylvania are received and any required waiting
periods have expired.


                                       14
<PAGE>

     If the Merger Agreement is approved by the required vote of Prime
shareholders, all other conditions of the Merger are satisfied or waived and
the Closing is held on the date set for closing ("Closing Date"), the effective
time of the Merger (the "Effective Time") will be the date and time specified
in the articles of merger required to be filed with the Secretary of State of
the Commonwealth of Pennsylvania (the "Merger Certificate") following the
Closing Date. If the Merger Agreement is approved by Prime shareholders on the
scheduled date of the Special Meeting, subject to the satisfaction or waiver of
certain other conditions described herein, we presently expect that the
Effective Time will occur during the third calendar quarter of 1999. The Merger
Agreement may be terminated by either party if, among other things, the Closing
fails to occur on or before January 3, 2000, 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. The Summit Board of Directors
("Summit Board") and the Prime Board each also has the right to terminate the
Merger Agreement under certain circumstances. See "THE MERGER -- The Merger
Agreement -- Conditions to the Merger; Termination."


Exchange of Prime Certificates

     Prior to the Effective Time, Summit will appoint First Chicago Trust
Company of New York or another entity reasonably satisfactory to Prime as the
exchange agent for the Merger ("Exchange Agent"). As promptly as practicable
after the Effective Time, but in no event more than 10 days after the Exchange
Agent receives an accurate and complete list of all holders of record of
outstanding Prime Common as of the Effective Time, Summit will cause the
Exchange Agent to send to each Prime shareholder a letter of transmittal and
instructions for exchanging their certificates representing Prime Common
("Prime Certificates") for a certificate representing the number of whole
shares of Summit Common ("Summit Certificate") and, if applicable, a check
representing a Cash In Lieu Amount, to which each shareholder is entitled as
Merger Consideration.

     To effect a proper surrender and exchange of Prime Certificates, all Prime
Certificates held by a particular Prime shareholder must be surrendered to the
Exchange Agent by the shareholder accompanied by properly executed and
completed letters of transmittal. Until a Prime shareholder has properly
surrendered Prime Certificates, Summit may, at its option, refuse to pay to the
holder dividends or other distributions, if any, payable to holders of Summit
Common; provided, however, that, upon proper surrender and exchange of Prime
Certificates, there will be paid to the holder the amount, without interest, of
dividends and other distributions, if any, which became payable prior thereto
but which were not paid. No transfer of Prime Common will be made on the stock
transfer books of Prime at and 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
any 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 Prime
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 instead the Cash In Lieu Amount.

     If more than one Prime Certificate is surrendered for the same Prime
shareholder account, the number of whole shares of Summit Common for which a
Summit Certificate will be issued to that owner pursuant to the Merger
Agreement will be computed on the basis of the aggregate number of shares of
Prime Common represented by all Prime Certificates so surrendered by that
account owner.

     Prime shareholders should not surrender their Prime Certificates for
exchange until a letter of transmittal, instructions and other exchange
materials are received from the Exchange Agent. However, Prime shareholders are
urged to notify American Stock Transfer and Trust Company, Prime's transfer
agent, now at (800) 937-5440 if their Prime Certificates are lost, stolen,
destroyed or not properly registered, in order to begin the process of issuing
replacement Prime Certificates.


Conversion of Prime Stock Options

     Each stock option relating to Prime Common ("Original Option") granted
pursuant to the Prime Bancorp, Inc. 1988 Stock Option Plan and the Prime
Bancorp, Inc. Incentive Stock Option Plan (together the "Prime


                                       15
<PAGE>

Option Plans") which is outstanding and unexercised at the Effective Time, will
be converted automatically at the Effective Time into an option to purchase
Summit Common ("New Option"). Subject to the adjustment in exercise price per
share and number of shares, described below, each New Option will continue to
be governed by the terms of the Prime Option Plan and the stock option
agreement by which it was evidenced, 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 Prime Common subject to
that option were issued and outstanding immediately prior to the Effective
Time, rounded down to the next lower full share (the "Converted Number"), and
(ii) the exercise price per share of Summit Common subject to the New Option
will be equal to the aggregate exercise price that would have been payable upon
exercise in full of the Original Option divided by the Converted Number.

     After the Effective Time and within 45 days after Summit receives an
accurate and complete list of all holders of Original Options, Summit will
issue to each holder of New Options, upon surrender 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 45 days after Prime shall have delivered to Summit the above
mentioned option-holder list.


Recommendation of Prime Board

     The Merger Agreement has been unanimously approved by the Prime Board. The
Prime Board believes that the Merger is in the best interests of Prime
shareholders. The Prime Board unanimously recommends that Prime shareholders
vote "FOR" the proposal to approve the Merger Agreement.


Background

     Management and the Prime Board, over the past several years, have
periodically evaluated the strategic alternatives and long-term goals of Prime
and Prime Bank as the pace of change within the banking industry and financial
services sector has accelerated. The strategic alternatives reviewed from
time-to-time included (1) remaining independent and continuing its strategy of
internal growth and expansion through acquisition, (2) engaging in a
merger-of-equals type transaction, or (3) a strategic combination with a larger
bank holding company.

     As was noted in Prime's 1997 Annual Report to shareholders, Prime intended
to continue to expand through internal growth and "through the acquisition of
first-rate community banks." This strategy led to analyses of, and discussions
with, several possible acquisition candidates that were reviewed with the Prime
Board in 1998. The Prime Board and management agreed at a meeting in April 1998
that the scope of review should be expanded to include a complete review of all
strategic alternatives -- acquisitions, merger-of-equals and merger into larger
bank holding companies.

     During the summer and early fall of 1998, Prime management actively
evaluated Prime's strategic options in regard to mergers with similarly-sized
and larger institutions, and made contact with certain executives of other bank
holding companies in order to establish or renew relationships as well as to
discuss common goals and operating objectives. These contacts, in one case,
included specific discussions over a period of several months, of the merits of
combining the respective companies. However, the parties were never able to
agree on the general structure of a combination that was acceptable to both
companies. During this period, Prime management also met with a number of
investment banking firms familiar with the banking industry for the purpose of
identifying possible candidates for strategic combinations.

     On December 14, 1998, Prime's Chairman, President and Chief Executive
Officer, James J. Lynch, met with John Howell, Chairman of Summit Bank
(Pennsylvania) and John Feeney, Executive Vice President of Summit and
exchanged ideas about market conditions in the Philadelphia region. At this
meeting the parties discussed the possible acquisition of Prime by Summit and
the common goals the two organizations had in regard to the eastern
Pennsylvania banking market.


                                       16
<PAGE>

     On January 6, 1999 Mr. Lynch met with Mr. John Collins, Vice Chairman of
Summit and Mr. Feeney. Mr. Joseph Semrod, Summit's Chief Executive Officer and
Robert Cox, President of Summit, also joined the meeting for a period of time.
At this meeting, Summit management expressed continued interest in the
acquisition of Prime and the benefit of adding Prime's management team to
Summit's Pennsylvania organization.

     During the period from January 6, 1999 through January 26, Prime had
limited discussions with representatives of two other large bank holding
companies regarding a possible business combination. Prime management had
previously discussed the possibility of a combination with both of these
companies. At the request of each company, Prime provided certain information
after confidentiality agreements were signed. However, these contacts did not
develop into active negotiations.

     At the regularly scheduled meeting of the Board of Directors on January
20, 1999, the Prime Board authorized Mr. Lynch to open formal negotiations with
Summit concerning the possible combination of the two companies. On January 21,
Mr. Collins and Mr. Feeney again met with Mr. Lynch in order to continue a
dialogue concerning the benefits of a possible combination and the organization
needed to serve the eastern Pennsylvania market.


     In a phone conversation in late January 1999, Mr. Collins suggested that
the companies exchange certain information to determine the feasibility of a
combination of the two companies. On January 26, 1999 Summit signed a
confidentiality agreement and Prime began to provide certain detailed business
and financial information.


     During late January, members of senior management of Summit and Prime
continued to review and evaluate the information provided in order to determine
whether or not to commence negotiations. During this period, Fox-Pitt, Kelton,
Inc. ("Fox-Pitt, Kelton") consulted with Prime regarding the potential value of
Prime and of Summit.


     On February 3, 1999, representatives of Prime and Fox-Pitt, Kelton met
with representatives of Summit to discuss the potential synergies and benefits
to be realized if Summit were to acquire Prime and combine Summit's
Pennsylvania banking operations with Prime Bank. On this date, Mr. Arthur J.
Kania, a member of the Prime Board, also met with Mr. Collins to discuss
strategies for the eastern Pennsylvania banking market and Summit's commitment
to the Prime management team, philosophy and culture. On February 5, Summit
made its initial proposal to acquire Prime. During the period from February 5
through February 10, the parties conducted negotiations regarding the principal
terms of the proposed transaction, including the exchange ratio and an option
for Summit to purchase a significant block of Prime Common upon the occurrence
of certain events.


     On February 10, Mr. Lynch held a number of telephone conversations
individually with the members of the Executive Committee of the Prime Board.
The members of the Executive Committee are Mr. Lynch, Mr. Kania, Mr. Fox, Mr.
Straw, Mr. Betz, Mr. Larenz and Mr. Peraino. The purpose of the conversations
was to review the terms of the proposed transaction with Summit. Mr. Lynch
discussed with the members the financial aspects of the proposal, the potential
benefits of a transaction to Prime and each of its subsidiaries, the expected
conditions to the consummation of a transaction with Summit and the expected
tax and accounting treatment of a merger.


     On February 11, Mr. Lynch met with Mr. Cox and Mr. Collins. During this
meeting the exchange ratio was discussed and tentatively set at 0.675 of a
share of Summit Common for each share of Prime Common in a tax-free exchange.
During the period from February 13 through February 17, Summit's and Prime's
senior management, along with their respective legal and financial advisors,
continued due diligence and negotiations regarding the proposed transaction,
including negotiating the terms of the definitive merger agreement, the stock
option agreement and related documents. On February 16, representatives of
Fox-Pitt, Kelton met with Summit senior executives in Princeton, New Jersey to
conduct further due diligence regarding Summit. A senior member of Prime's
staff and Prime's legal counsel were also present and conducted additional due
diligence.


     On February 17, Prime's management and its legal and financial advisors
presented the terms of the proposed merger, including the Exchange Ratio, to
the Prime Board at a special meeting. Under the terms of the negotiated
transaction, Summit would issue 0.675 of a share of Summit Common for each
share of Prime Common outstanding in a tax-free exchange. Prime's financial
advisor, Fox-Pitt, Kelton, rendered its opinion that, as of such date, the
Exchange Ratio was fair, from a financial point of view, to the holders of
Prime Common. The


                                       17
<PAGE>

Prime Board also considered the advice of Fox-Pitt, Kelton regarding certain
other financial terms of the transaction. Legal counsel made presentations
regarding the principal terms of the proposed transaction, the legal documents
and the fiduciary duties of the Prime Board. After such presentations and
discussions, including due consideration of the foregoing matters, the Prime
Board determined that the Merger Agreement and the transactions contemplated
thereby, including the stock option agreement, were in the best interests of
Prime, its shareholders and other constituencies. Accordingly, the Prime Board
approved and adopted the Merger Agreement and the transactions contemplated
thereby.

     The Summit Board also approved the Merger Agreement at a meeting on
February 17, 1999. On the evening of February 17, the parties executed the
Merger Agreement and the stock option agreement was executed as of February 18,
1999.


Reasons for the Merger

     Prime. At its meeting on February 17, 1999, the Prime Board determined
that the Merger and the terms of the Merger Agreement are fair, from a
financial point of view, to Prime and the Prime shareholders and are in the
best interests of Prime, the Prime shareholders, employees and customers and
the communities which Prime Bank serves. Accordingly, the Prime Board
unanimously approved and adopted the Merger Agreement and recommends approval
of the Merger Agreement by the Prime shareholders. In reaching its decision,
the Prime Board consulted with Prime's management, legal counsel and Fox-Pitt,
Kelton, Prime's financial advisor for this transaction. The Board considered a
number of factors, including the following:


o The investment in capital and people that would be needed to make Prime's
  operating capabilities fully competitive with the much larger banks in the
  eastern Pennsylvania markets it serves;

o Technology costs, lending limits and the investments necessary to increase
  branch penetration that were deemed impediments to improving Prime's
  operating returns to attractive levels;

o The cost of acquiring banking franchises in order to expand Prime's market
  and improve economies of scale would likely be expensive and dilutive to
  existing shareholders;

o The business operations of both Prime and Summit on an historical and
  prospective basis and the prospective results of the combined companies on a
  pro forma basis, considering the potential cost savings and revenue
  enhancements which might result from the Merger;

o Historical trading ranges for both Summit Common and Prime Common;

o The value of the consideration offered by Summit and the increase in dividend
  payments to Prime shareholders after the Merger;

o The need for each organization to improve its service to the eastern
  Pennsylvania markets and Summit's commitment to these markets;

o The current and prospective economic and competitive environment for banks in
  the eastern Pennsylvania markets;

o The commitment by Summit to appoint Mr. Lynch as the chief executive officer
  of Summit's Pennsylvania operations;

o Summit's desire to utilize Prime's management, experienced commercial and
  real estate lending teams and branch network, presenting additional career
  opportunities for most of Prime's employees;

o Prime's need to expand product offerings which can be achieved with the
  addition of Summit's trust powers, asset management services and other
  banking products;

o The premium offered by Summit for Prime in terms of (i) the ratio of price to
  last twelve (12) months earnings per share, (ii) the ratio of price to book
  value, (iii) the ratio of price to tangible book value, and (iv) market
  price;

o Summit's asset base and financial strengths;

                                       18
<PAGE>

o The due diligence conducted by management, legal advisors and Fox-Pitt,
  Kelton and the analyses and opinions expressed by Fox-Pitt, Kelton;

o The expectation that the Merger will qualify as a tax-free reorganization for
  federal income tax purposes;

o The financial and other terms and conditions of the Merger Agreement and
  related documents, including but not limited to the provisions relating to
  severance benefits for those employees whose employment may be terminated in
  connection with the Merger;

o The opportunity for Prime to continue its corporate culture as part of
  Summit, enhanced by Summit's commitment to serving middle market companies
  and its strong product offerings;

o The terms of the stock option agreement, which might discourage third parties
  from seeking to acquire Prime;

o The likelihood of obtaining necessary regulatory approvals;

o Other strategic options which had been investigated and explored by Prime
  management and the Prime Board since January 1, 1998; and

o The effect of the Merger generally on the shareholders, employees and
  customers of Prime and the communities which it serves.

     The foregoing discussion of the information and factors considered by the
Prime Board is not intended to be all-inclusive, but includes all material
factors considered by the Prime Board. In reaching its determination to approve
the Merger Agreement, the Prime Board did not assign any relative or specific
weights to the various factors considered nor did the Prime Board specifically
characterize any factor as positive or negative, except as specifically stated
above. Individual directors may have given different weights to the various
factors and may have viewed certain factors more positively or negatively than
other directors.

Summit. The Summit Board believes the Merger will enhance Summit's retail
franchise and competitive position in key market areas.


Opinion of Prime's Financial Advisor

     Fox-Pitt, Kelton has acted as financial advisor to Prime in connection
with the Merger. As part of its engagement, Fox-Pitt, Kelton delivered its oral
opinion to the Prime Board at the February 17, 1999 Prime Board meeting that,
as of February 16, 1999 and based upon and subject to various considerations
set forth in the opinion, the Exchange Ratio was fair from a financial point of
view to the holders of the Prime Common. Fox-Pitt, Kelton subsequently
confirmed its opinion in writing and again as of the date of this Proxy
Statement-Prospectus. Except as discussed herein, no limitations were imposed
by the Prime Board upon Fox-Pitt, Kelton with respect to investigations made or
the procedures followed by Fox-Pitt, Kelton in rendering its opinion.

     The full text of the written opinion by Fox-Pitt, Kelton, dated the date
of this Proxy Statement-Prospectus, which sets forth the assumptions made,
matters considered and qualifications and limitations on the review undertaken,
is attached as Appendix B to this Proxy Statement-Prospectus. Prime
shareholders are urged to read this opinion carefully and in its entirety.
Fox-Pitt, Kelton's opinion is directed only to the fairness of the Exchange
Ratio to the holders of the Prime Common from a financial point of view, has
been provided to the Prime Board in connection with its evaluation of the
Merger, does not address the merits of the underlying decision by Prime to
engage in the Merger, and does not constitute a recommendation to any Prime
shareholder as to how the shareholder should vote. The summary of the opinion
of Fox-Pitt, Kelton set forth in this Proxy Statement-Prospectus is qualified
in its entirety by reference to the full text of the opinion.

     In arriving at its opinion, Fox-Pitt, Kelton, among other things:

   o Reviewed and analyzed certain publicly available financial statements for
     Prime and Summit and financial information made available to Fox-Pitt,
     Kelton by the management of Prime and Summit;

   o Analyzed certain internal financial statements, including financial
     projections and other financial and operating data prepared by the
     management of Prime;


                                       19
<PAGE>

   o Discussed the past, present and future operations, financial condition
     and prospects of Prime and Summit with the management of Prime and Summit,
     respectively;

   o Reviewed the stock price performance and trading activity of Prime
     Common and Summit Common;

   o Compared the financial performance and condition of Prime and Summit with
     that of certain other comparable publicly traded companies;

   o Reviewed and discussed with the management of Prime and Summit the
     strategic objectives of the Merger and certain other benefits of the
     Merger;

   o Reviewed the financial terms, to the extent publicly available, of
     certain merger and acquisition transactions comparable, in whole or in
     part, to the Merger;

   o Reviewed the Merger Agreement and the stock option agreement; and

   o Performed such other analyses and investigations as Fox-Pitt, Kelton
     deemed appropriate.

     In rendering its opinion, Fox-Pitt, Kelton assumed and relied upon,
without independent verification, the accuracy and completeness of all of the
financial and other information reviewed by it for the purposes of providing
its opinion, and did not assume any responsibility for independent verification
of the information. Fox-Pitt, Kelton did not assume any responsibility for
independent valuation and appraisal of the assets and liabilities of Prime nor
did it assume any responsibility for reviewing loan files or visiting branch
locations. With respect to financial projections, Fox-Pitt, Kelton assumed that
they were reasonably prepared by the management of Prime on bases reflecting
the best currently available estimates and judgments of the future financial
performance of Prime. Fox-Pitt, Kelton expresses no view as to the
reasonableness of the projections provided or the assumptions on which they
were based. Fox-Pitt, Kelton also assumed that the Merger would be consummated
in accordance with the terms of the Merger Agreement without material waiver or
modification. Fox-Pitt, Kelton's opinion dated February 17, 1999, and its
opinion dated the date of this Proxy Statement-Prospectus are based upon
economic, market and other conditions as they existed and could be evaluated on
February 16, 1999, and [________, 1999], respectively.

     The forecasts or projections furnished to Fox-Pitt, Kelton for Prime were
prepared by the management of Prime. As a matter of policy, Prime does not
publicly disclose internal management forecasts, projections or estimates of
the type furnished to Fox-Pitt, Kelton in connection with its analysis of the
Merger, and such forecasts, projections and estimates were not prepared with a
view towards public disclosure. These forecasts, projections and estimates were
based on numerous variables and assumptions which are inherently uncertain and
which may not be within the control of management, including, without
limitation, general economic, regulatory and competitive conditions.
Accordingly, actual results could vary materially from those set forth in the
forecasts, projections and estimates provided by the management of Prime.

     The following is a summary of the material analyses presented by Fox-Pitt,
Kelton to the Prime Board at its meeting held on February 17, 1999.

     Comparable Public Company Analyses. Fox-Pitt, Kelton reviewed certain
financial, operating and stock market performance data of 27 publicly traded
banks and bank holding companies headquartered in the Mid-Atlantic region of
the United States, each with assets between $500 million and $1.5 billion as of
the most recent period publicly available (the "Prime Peer Companies").
Fox-Pitt, Kelton analyzed the relative performance and value of Prime by
comparing certain publicly available financial data of Prime with that of the
Prime Peer Companies, including ratios of loans to deposits and equity to
assets, and multiples of market price to earnings per share as of the last
twelve months, market price to estimated earnings per share in 1998, and market
price to book value. The operating data for Prime was as of or for the twelve
month period ended December 31, 1998 and the operating data for the Prime Peer
Companies was as of or for the last twelve month reporting period for each
company. All stock prices were as of the market close on February 16, 1999. The
analyses yielded the following comparison of the medians for the Prime Peer
Companies with Prime, respectively:

     o Loans to deposits ratios of 77.2% and 93.5%;

     o Equity to assets ratios of 8.9% and 8.6%;

                                       20
<PAGE>

     o Market price to earnings per share multiples for the last twelve months
       of 16.1x and 16.7x;

     o Market price to estimated (or actual if available) earnings per share in
       1998 of 13.3x and 14.8x; and

     o Market price to book value multiples of 200% and 220%.

     Fox-Pitt, Kelton performed similar analyses with respect to Summit.
Fox-Pitt, Kelton reviewed and compared certain financial, operating and stock
market performance data of Summit with 13 publicly traded banks and bank
holding companies in the United States, each with assets between $20 billion
and $40 billion as of the most recent period publicly available (the "Summit
Peer Companies"). Fox-Pitt, Kelton analyzed the relative performance and value
of Summit by comparing certain publicly available financial data of Summit with
that of the Summit Peer Companies, including ratios of loans to deposits and
equity to assets, and multiples of market price to earnings per share as of the
last twelve months, market price to estimated earnings per share in 1998, and
market price to book value. The operating data for Summit was as of or for the
twelve month period ended December 31, 1998 and the operating data for the
Summit Peer Companies was as of or for the last twelve month reporting period
for each company. All stock prices were as of the market close on February 16,
1999. These analyses yielded the following comparison of the medians for the
Summit Peer Companies with Summit, respectively.

     o Loans to deposits ratios of 94.7% and 91.3%;

     o Equity to assets ratios of 8.2% and 8.2%;

     o Market price to earnings per share multiple for the last twelve months
       of 21.2x and 14.9x;

     o Market price to estimated (or actual if available) earnings per share in
       1998 of 14.9x and 13.8x; and

     o Market price to book value multiple of 273% and 250%.

     Comparable Transactions Analyses. Fox-Pitt, Kelton reviewed the
consideration paid or proposed to be paid in other transactions in 1998 and
1999 involving banks and bank holding companies. Specifically, Fox-Pitt, Kelton
analyzed 17 transactions in which the seller had assets between $500 million
and $1.5 billion and returns on average assets of 1.0% or greater as of the
most recent period publicly available (the "Comparable Transactions"). The
ratios provided below assume a Summit Common price of $39.19 (the reported
price per share of Summit Common on February 16, 1999). In reviewing the
Comparable Transactions, Fox-Pitt, Kelton examined the multiples of price paid
relative to previous twelve-month earnings, price-to-book value, the premium
over tangible book value to core deposits and the five trading day market
premium. These analyses yielded the following comparison of the medians for the
Comparable Transactions with the Merger, respectively:

     o Price to earnings multiple for the last twelve months of 24.4 x and
       24.5x;

     o Price to book value ratios of 311.8% and 323.4%;

     o Price to tangible book value ratios of 326.3% and 337.7%;

     o Tangible book value premium to core deposits ratios of 27.6% and 32.3%;
       and

     o Premium to seller common stock price of 123.8% and 147.0%.

     Stock Trading History. Fox-Pitt, Kelton reviewed the performance of the
weekly stock prices and trading volume of the Prime Common and Summit Common
during the period from January 2, 1998 through February 16, 1999. Fox-Pitt,
Kelton compared the per share stock price and trading volume of Prime Common to
the Prime Peer Companies and compared the per share market price and trading
volume of Summit Common to the Summit Peer Companies.

     Pro Forma Merger Analyses. Fox-Pitt, Kelton estimated the impact of the
proposed Merger on Summit's projected fully diluted estimated earnings per
share for 2000. Fox-Pitt, Kelton based its analysis on equity analysts'
consensus estimates with respect to projected future earnings of Prime and
Summit and it conducted conversations with the management of Summit and Prime
regarding those estimates. Based on this information, and the terms of the
proposed Merger, Fox-Pitt, Kelton concluded that, for Summit, the Merger could
have an immaterial dilutive effect (before taking into account various cost
savings and revenue enhancements which


                                       21
<PAGE>

could be accomplished upon consolidation of Prime's and Summit's operations) on
estimated fully diluted earnings per share in 2000. Fox-Pitt, Kelton also
calculated that the Merger could have an immaterial accretive effect on
Summit's earnings per share in 2000 if pre-tax costs savings and revenue
enhancements estimated by Prime could be achieved. Separately, Fox-Pitt, Kelton
also determined that the Merger would have an accretive effect on Prime's
dividend per share of approximately 84%, based on Summit's and Prime's then
current dividend payments.


     Dividend Discount Analysis. Fox-Pitt, Kelton performed an analysis to
calculate a range of present values per share of Prime Common assuming Prime
continued to operate as a stand-alone entity. The range was determined by
adding (i) the present value of the estimated future dividend stream that Prime
could generate over the period beginning December 31, 1998, and ending on
December 31, 2003, and (ii) the present value of the terminal value of Prime
Common on December 31, 2003. To determine a projected dividend stream,
Fox-Pitt, Kelton assumed (i) an increase in assets of 8% each year from 1999
through 2003; (ii) an increase in net income of 12% each year from 1999 through
2003; and (iii) a dividend payout ratio of 36.50% each year from 1999 through
2003.


     The terminal values are based upon a range of price-to-earnings and
price-to-book value multiples consistent with the range of price-to-earnings
and price-to-book value multiples at which similarly-sized banking institutions
located in the United States have been sold in 1998-99 (13x to 15x previous
twelve month earnings per share and 2.0x to 2.2x book value per share) and a
range of discount rates (12% to 16%). Applying the foregoing multiples,
discount rates and assumptions, Fox-Pitt, Kelton determined that the fully
diluted value per share of Prime Common ranged from approximately $13.55 to
$18.16 based on the price-to-earnings multiple assumptions and $14.32 to $18.41
based on the price-to-book value multiple assumptions.


     In arriving at its opinion, Fox-Pitt, Kelton performed a variety of
financial analyses, the material portions of which are summarized above. The
summary set forth above does not purport to be a complete description of the
analyses performed by Fox-Pitt, Kelton or of Fox-Pitt, Kelton's presentation to
the Prime Board. The preparation of a fairness opinion is a complex analytical
process involving various determinations as to the most appropriate and
relevant methods of financial analyses and the application of those methods to
the particular circumstances and, therefore, such an opinion is not necessarily
susceptible to partial analysis or summary description. In arriving at its
opinion, Fox-Pitt, Kelton did not attribute any particular weight to any
analysis or factor considered by it, but rather made qualitative judgments as
to the significance and relevance of each analysis and factor. Accordingly,
Fox-Pitt, Kelton believes that its analyses must be considered as a whole and
that selecting portions of such analyses and the factors considered by it,
without considering all such analyses and factors, could create an incomplete
view of the process underlying its analyses set forth in its opinion. With
regard to the Comparable Public Company Analyses and the Comparable
Transactions Analyses summarized above, Fox-Pitt, Kelton selected comparable
public companies on the basis of various factors; however no public company or
transaction utilized as a comparison is identical to Prime, Summit or the
Merger. Accordingly, an analysis of the foregoing is not mathematical; rather,
it involves complex considerations and judgments concerning differences in
financial and operating characteristics of the comparable companies and other
factors that could affect the acquisition or public trading value of the
comparable companies and transactions to which Prime, Summit and the Merger are
being compared.


     Fox-Pitt, Kelton's opinion does not imply any conclusion as to the likely
trading range for Summit Common following consummation of the Merger, and do
not address Prime's underlying business decision to effect the Merger. In
performing its analyses, Fox-Pitt, Kelton made numerous assumptions with
respect to industry performance, general business, economic, market and
financial conditions and other matters, many of which are beyond the control of
Prime and Summit. Any estimates contained in such analyses are not necessarily
indicative of actual past or future results or values, which may be
significantly more or less than such estimates. Actual values will depend upon
several factors, including changes in interest rates, dividend rates, market
conditions, general economic conditions and other factors that generally
influence the price of securities.


     Fox-Pitt, Kelton is an internationally recognized investment banking firm
and was selected by Prime based on Fox-Pitt, Kelton's experience and expertise.
Fox-Pitt, Kelton regularly engages in evaluation of bank and


                                       22
<PAGE>

bank holding company securities in connection with acquisitions, negotiated
underwritings, secondary distributions of listed and unlisted securities,
private placements and valuations for various other purposes. In the ordinary
course of its business, Fox-Pitt, Kelton may effect transactions, for its own
account or for the account of customers, and hold at any time a long or short
position in securities of Prime or Summit.

     In connection with the preparation of its opinion, Fox-Pitt, Kelton was
not authorized by the Prime Board to solicit, nor has Fox-Pitt, Kelton
solicited, third party indications of interest for the acquisition of all or
part of Prime.

     Pursuant to a letter agreement dated February 5, 1999, between Prime and
Fox-Pitt, Kelton, Fox-Pitt, Kelton agreed to act as financial advisor to Prime
in connection with the Merger. Prime paid Fox-Pitt, Kelton a $50,000 retainer
upon execution of the letter agreement and $450,000 upon the execution of the
Merger Agreement. Prime has also agreed to pay Fox-Pitt, Kelton, a transaction
fee of 0.75% of the aggregate consideration paid or payable by Summit upon
consummation of the Merger which will be determined as of the Closing Date. The
$50,000 retainer and $450,000 paid upon execution of the Merger Agreement are
to be credited against the transaction fee of 0.75% of the aggregate
consideration. Prime has agreed to reimburse Fox-Pitt, Kelton for its
reasonable out-of-pocket expenses, including travel, outside legal fees and
related charges, and to indemnify Fox-Pitt, Kelton and related persons against
certain liabilities, including certain liabilities under the federal securities
laws, from and arising out of or based upon Fox-Pitt, Kelton's engagement on
its behalf.


Stock Option Agreement

     As an inducement and condition to Summit's willingness to enter into the
Merger Agreement, Prime (as issuer) entered into the Prime Bancorp, Inc. Stock
Option Agreement dated as of February 18, 1999 (the "Merger Option Agreement")
with Summit (as grantee). The following discussion highlights selected
information from the Merger Option Agreement but may not contain all the
information which is important to you. To understand the Merger Option
Agreement fully you should read carefully this entire document which is
included as Appendix C hereto.

     Pursuant to the Merger Option Agreement, Prime granted to Summit an
irrevocable option (the "Prime Option"), exercisable under certain limited and
specifically defined circumstances, none of which, to the best of Summit's and
Prime's knowledge, has occurred as of the date hereof, to purchase up to
1,087,498 shares of Prime Common at a price of $18.00 per share, the last sale
price on February 17, 1999, the last full trading day prior to the announcement
of the signing of the Merger Agreement. In addition, Prime agreed to pay Summit
a "break up" fee of $5 million in the event the Prime Option becomes
exercisable and is exercised in full by Summit. The purchase of any shares of
Prime Common pursuant to the Prime Option is subject to compliance with
applicable law.


     If Summit is in breach of any material covenant or obligation contained in
the Merger Agreement and, if the Merger Agreement has not been terminated prior
thereto, that breach would entitle Prime to terminate the Merger Agreement. In
this event, Summit will not be permitted to exercise the Prime Option.
Otherwise, Summit may exercise the Prime 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 Prime Option will terminate upon the earliest
to occur of certain events, including:


   o the time immediately prior to the Effective Time;


   o 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) a material breach thereof by Prime which has not been
     cured or is not capable of being cured within the time allotted, (b)
     nonsatisfaction of a condition to Summit's obligation to close the Merger
     (other than failure to obtain shareholder approval of the Merger Agreement
     or failure to obtain the fairness opinion of Fox-Pitt Kelton), or (c) the
     Prime Board's failure to recommend, or withdrawal of, or making an adverse
     change to its recommendation, to Prime shareholders to approve the Merger
     Agreement); or


   o 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) a material breach by


                                       23
<PAGE>

     Prime which has not been cured or is not capable of being cured within the
     time allotted, (b) nonsatisfaction of a condition to Summit's obligation
     to close the Merger (other than failure to obtain shareholder approval of
     the Merger Agreement or failure to obtain the fairness opinion of
     Fox-Pitt, Kelton), or (c) the Prime Board's failure to recommend, or
     withdrawal of, or making an adverse change to, its recommendation to Prime
     shareholders to approve the Merger Agreement.

     The term "Extension Event" shall mean the occurrence of certain events
without Summit's prior written consent, including:

   o Prime, the Prime Board or any of its subsidiaries taking certain actions
     (each an "Acquisition Transaction"), including recommending to
     shareholders the approval of, or entering into an agreement with any third
     party to effect, (a) a merger, consolidation or similar transaction
     involving Prime or any of its banking subsidiaries, (b) the purchase,
     lease, or other acquisition of ten percent or more of the aggregate value
     of the assets or deposits of Prime or any of its banking subsidiaries, (c)
     the purchase or other acquisition of securities representing ten percent
     or more of the voting power of Prime or any of its banking subsidiaries or
     (d) any substantially similar transaction, in each case except as
     otherwise permitted by the Merger Agreement;

   o any third party's acquiring beneficial ownership or the right to acquire
     beneficial ownership of ten percent or more of the aggregate voting power
     of Prime or any of its banking subsidiaries;

   o any third party's making a bona fide proposal to Prime or its
     shareholders, 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 ten percent or more of the aggregate voting power of Prime or any
     of its banking subsidiaries);

   o after a proposal by a third party to Prime or its shareholders to engage
     in an Acquisition Transaction, Prime breaches (without curing within the
     time allotted) any representation or covenant in the Merger Agreement
     which would entitle Summit to terminate the Merger Agreement;


   o any third party's filing an application with any federal or state bank
     regulatory authority for approval to engage in an Acquisition Transaction;
     or


   o any Purchase Event (as defined below).


     The term "Purchase Event" shall mean any of the following events or
transactions:


   o any person's (other than Summit or a subsidiary of Summit) acquiring
     beneficial ownership of 25 percent or more of the aggregate voting power
     of Prime or any of its banking subsidiaries, except as otherwise permitted
     by the Merger Agreement; or


   o failure of the Prime Board to call a meeting for consideration of the
     Merger or cancellation of such a meeting, or if the Prime Board shall have
     withdrawn or modified in a manner adverse to the consummation of the
     Merger its recommendation with respect to the Merger Agreement, in each
     case after an Extension Event; or


   o the occurrence of an Extension Event described in the first bullet 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 Prime Option (or shares issued
pursuant to the exercise thereof) must be repurchased by Prime or converted
into, or exchanged for, an option of another corporation or Prime. In addition,
the Merger Option Agreement grants certain registration rights to Summit with
respect to the shares represented by the Prime Option. The terms of such
repurchase, substitute option and registration rights are set forth in the
Merger Option Agreement.


     In the event that the Prime Option becomes exercisable and Summit
exercises the Prime Option in full, Prime is required to pay Summit $5 million
(the "Breakup Fee") which may be applied as an offset to Summit's obligation to
pay the aggregate purchase price for the shares of Prime Common underlying the
Prime Option. The Merger Option Agreement and Prime Option are intended to
increase the likelihood that the Merger will be


                                       24
<PAGE>

consummated according to the terms set forth in the Merger Agreement and may be
expected to discourage offers by third parties to acquire Prime prior to the
Merger. To the knowledge of Summit and Prime, no event giving rise to the right
to exercise the Prime Option has occurred as of the date of this Proxy
Statement-Prospectus.


Regulatory Approvals


     The Merger is subject to approval by the Federal Reserve Board under the
Bank Holding Company Act of 1956, as amended (the "BHC Act"). The BHC Act
provides that the Federal Reserve Board may not approve any transaction (1)
that would result in a monopoly, or that would be in furtherance of any
combination or conspiracy to monopolize or to attempt to monopolize the
business of banking in any part of the United States, or (2) the effect of
which in any section of the country may be substantially to lessen competition,
or to tend to create a monopoly, or that in any other manner would be in
restraint of trade, unless the Federal Reserve Board finds that the
anticompetitive effects of the proposed transaction are clearly outweighed in
the public interest by the probable effect of the transaction in meeting the
convenience and needs of the communities to be served. In conducting its review
of any application for approval, the Federal Reserve Board is required to
consider the financial and managerial resources and future prospects of the
company or companies and the banks concerned, and the convenience and needs of
the communities to be served. 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 5%
or more of Prime's voting stock is subject to the same requirement for
approval.


     The BHC Act provides that a transaction approved by the Federal Reserve
Board may not be consummated for 30 days after the approval is received or, if
certain conditions are met, a shorter period, but, in the absence of an
emergency, not less than 15 calendar days after the date of approval. During
this period, the U.S. Department of Justice may commence legal action
challenging the transaction under the antitrust laws. If, however, the U.S.
Department of Justice does not commence legal action during the specified
waiting period, it may not challenge the transaction thereafter except in an
action commenced under Section 2 of the Sherman Antitrust Act. Satisfactory
financial condition, particularly with regard to capital adequacy, and
satisfactory Community Reinvestment Act ratings generally are prerequisites to
obtaining Federal Reserve Board approval to make acquisitions. All of Summit's
subsidiary banks are currently rated "outstanding" under the Community
Reinvestment Act.


     An application with respect to the Merger was filed by Summit with the
Federal Reserve Board on April 9, 1999. Regulations of the Federal Reserve
Board under the BHC Act require notices of an application for approval of the
Merger to be published in newspapers of general circulation and in the Federal
Register and the public to 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 that a meeting would be appropriate. In addition, if an applicant or a
protester requests a hearing or if the Federal Reserve Board determines to hold
a hearing, the Federal Reserve Board may order that a formal hearing on the
application 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, the Federal Reserve Board's
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 expires on or about May 10, 1999.


     The acquisition of Prime by Summit is also subject to the approval by the
Pennsylvania Department of Banking ("PDOB"). The factors that the PDOB will
consider in determining whether to grant its approval include the competitive
effects of the Merger, principles of safe and sound banking, the public
interest and the


                                       25
<PAGE>

needs of the communities served by Prime and Summit. An application for
approval of the acquisition of Prime by Summit was filed with the PDOB on April
9, 1999. The merger of Prime Bank into Summit Bank (Pennsylvania) is also
subject to receipt of approval by the PDOB, which was requested in the
application filed on April 9, 1999.

     Prime shareholders should be aware that regulatory approvals of the Merger
may be based upon different considerations than those that would be important
to shareholders in determining whether or not to approve the Merger. Any
regulatory approvals should in no event be construed by a Prime shareholder as
a recommendation by any regulatory agency with respect to the Merger.


Interests of Certain Persons in the Merger


     Directors and executive officers of Prime have certain interests in the
Merger that are different from and in addition to their interests as Prime
shareholders. 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 Prime or any subsidiary of Prime 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 and the Articles of
Incorporation and Bylaws of Prime or the applicable subsidiary of Prime as in
effect on the date the Merger Agreement was executed and to the extent
permitted by law.


     In the Merger Agreement, Summit also agreed that, subject to Prime'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, for a period of six years after the
Effective Time, Summit would use its best efforts to provide to the persons who
served as directors or officers of Prime or any subsidiary of Prime on or
before 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
more than 200% of the amount expended by Prime 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. Prime must renew any existing insurance or purchase any
"discovery period" insurance provided for under existing insurance at Summit's
request.


Board of Directors and Officers of Summit and Summit Bank (Pennsylvania)


     The members of the Summit Board and the executive officers of Summit
immediately prior to the Effective Time will continue to be the members of the
Summit Board and executive officers of Summit at the Effective Time.


     Upon the completion of the Merger, James J. Lynch will be appointed
Chairman of the Board and Chief Executive Officer of Summit Bank (Pennsylvania)
and Senior Executive Vice President of Summit.


     Summit expects that certain members of the Prime Board will become members
of the Summit Bank (Pennsylvania) Board of Directors, although no decisions in
this regard have been made.


Employment Agreements


     Prime and Prime Bank have entered into employment agreements with James J.
Lynch and William H. Bromley which provide for certain payments to each
executive in the event he terminates his employment for


                                       26
<PAGE>

"good reason" (as defined in the agreements) in connection with a "change in
control" (as defined in the agreements). Mr. Lynch's agreement provides that if
he terminates his employment for "good reason" in connection with a "change in
control", he is entitled to receive a severance payment equal to 2.99 times his
average aggregate annual compensation during the preceding five calendar years.
Under Mr. Bromley's agreement, if he terminates his employment for "good
reason" in connection with a "change in control", he is entitled to a severance
payment equal to two times his average aggregate annual compensation during the
preceding three years. In both cases, the severance payments will be reduced to
the extent necessary to ensure that no portion of the severance payments are
subject to the excise tax imposed by Section 4999 of the Internal Revenue Code
of 1986, as amended ("Code").


     Prime and Prime Bank have also entered into a Change in Control Agreement
with James E. Kelly which provides for payments to Mr. Kelly after a "change in
control" of Prime in the event his employment is terminated or he terminates
his employment with Prime for "good reason". Upon such termination of
employment, Mr. Kelly is entitled to receive severance payments equal to the
sum of (A) two times his highest annual base salary during the preceding five
years and (B) a prorated portion of the cash bonus received by Mr. Kelly for
the prior fiscal year.


     The Merger will constitute a "change in control" under each of the
foregoing agreements. If Messrs. Lynch, Bromley or Kelly were to become
entitled to receive payments under their agreements with Prime, the estimated
amounts of payments (based upon their compensation through December 31, 1998)
would be $1,283,458, $520,000 and $344,875, respectively.


     Upon the effectiveness of the Merger, James J. Lynch will become Chairman
of the Board and Chief Executive Officer of Summit Bank (Pennsylvania) and
Senior Executive Vice President of Summit, and will receive an annual base
salary of not less than $345,000 and an annual cash bonus of not less than
$120,750. Summit has also agreed to include Mr. Lynch as a participant in the
Summit Bancorp. Executive Severance Plan (the "Severance Plan") and enter into
a termination agreement (the "Termination Agreement") with Mr. Lynch.


     Mr. Lynch's participation in the Severance Plan and the Termination
Agreement will supersede and extinguish his employment agreement and severance
arrangements with Prime, with the exception of the provisions relating to stock
options and he will therefore not be entitled to receive the payments described
under his agreement with Prime described above as a result of the Merger. Upon
receiving a payment under the Severance Plan or his Termination Agreement, Mr.
Lynch would be required to agree not to accept employment with another bank,
savings and loan association or credit union, or holding company thereof, at a
principal place of employment within 25 miles of Summit or a Summit subsidiary
bank office then in existence.


     The Severance Plan provides that, in the event a participant's employment
is terminated by Summit or one of its subsidiaries, other than for "Cause" (as
defined in the Severance Plan), death, disability or retirement, or by the
participant for "Good Reason" (as defined in the Severance Plan) within 6
months of any event alleged to constitute Good Reason, the participant, upon
signing a Release, Covenant Not to Sue and Non-Disclosure and Non-Solicitation
Agreement in the form set forth in the Severance Plan, is entitled to receive:


   o a lump sum cash payment equal to two times the highest annual rate of
     base salary in effect for the participant during the twelve-month period
     preceding the notice of termination;


   o a lump sum cash payment equal to two times the highest annual cash
     incentive bonus earned by the participant during the three fiscal years
     preceding the date of termination;


   o two years of employee benefit plans participation and outplacement
     services and one year of perquisites or the cash equivalent.


     All payments and benefits (other than outplacement services and continued
perquisites) are reduced pro rata within two years of normal retirement;


     The Severance Plan generally defines "Good Reason" to include:


   o the assignment of duties which are inconsistent with the participant's
     then title and salary grade or a significant reduction in the
     participant's authority and responsibility as a senior executive;


                                       27
<PAGE>

   o the removal of the participant from, or any failure to reappoint or
     reelect a participant to, the title of Executive Vice President or above;


   o a reduction in the participant's salary or the failure to grant increases
     in the participant's salary comparable to those granted executives of
     Summit or its subsidiaries of comparable title, salary grade and
     performance ratings;


   o locating the participant's office anywhere other than an executive office
     of Summit or a subsidiary located in New Jersey or Pennsylvania within
     sixty miles of Corporate Headquarters;


   o the failure to provide the participant with welfare benefits, perquisites
     and participation in all cash and stock bonus and incentive plans of
     Summit on substantially the same terms as provided to executives of
     comparable title and salary grade; or


   o notice from Summit or a subsidiary that the participant's participation
     in the Severance Plan or the participant's Termination Agreement,
     described below, would not be renewed.


     Mr. Lynch's participation letter under the Severance Plan will provide
that "Good Reason" includes a termination of employment by Mr. Lynch for any
reason other than disability or retirement during the nineteenth full calendar
month following the Effective Time. In addition, Mr. Lynch's participation
letter will further provide that in the event he is entitled to receive
benefits under the Severance Plan during the period from the Effective Time
through the end of the nineteenth full calendar month thereafter, Mr. Lynch
shall be entitled to receive a lump sum cash amount equal to 2.99 times his
base salary and bonus, subject to reduction if necessary to avoid payment of
excise taxes, rather than the two times base salary and bonus provided for
under the Severance Plan. After the nineteenth full calendar month following
the Effective Time, the foregoing special provisions provided for Mr. Lynch's
participation letter shall expire and he will be entitled to the rights and
benefits provided generally under the Severance Plan.


     The Termination Agreement between Summit and Mr. Lynch will provide that
in the event any person or entity takes certain steps designed to effect a
"Change in Control", as defined below, of Summit, Mr. Lynch will not
voluntarily leave the employ of Summit, except during the nineteenth month
window period described in the paragraph above or upon his normal retirement
date and will continue to perform his regular duties and services for Summit
until the person or entity has abandoned or terminated efforts to effect a
Change in Control or until a Change in Control has occurred. The Termination
Agreement will provide that if, within three years after a Change in Control of
Summit, Mr. Lynch's employment with Summit or Summit Bank is terminated by
Summit, other than for Cause, as defined in the Termination Agreement, his
death occurring more than 13 months after the Change in Control, disability or
retirement, or by Mr. Lynch for "Good Reason", as defined below, Mr. Lynch will
be entitled to receive:

   o a lump sum cash payment equal to the difference between (A) the sum of
     three times his base salary at the highest rate in effect during the
     twelve-month period preceding the notice of termination, plus three times
     the highest annual cash bonus earned by him during the three preceding
     fiscal years, and (B) the aggregate lump sum cash amounts relating to base
     salary and bonus payable to him under the Severance Plan in the event of
     the termination of his employment; and

   o upon retirement an amount of total retirement benefits equal to that
     which he would have received from defined benefit retirement plans of
     Summit, if his employment had continued for ten years beyond the
     termination date or until his normal retirement date, if earlier.

     Mr. Lynch will also be entitled to remain an active participant in most
employee benefit plans of Summit for a period of 36 months after the date of
termination. The Termination Agreement will further provide that in the event
any payment or benefit received or to be received by Mr. Lynch pursuant to the
Termination Agreement or any other plan, arrangement or agreement of Summit or
Summit Bank would, in the opinion of independent tax counsel, be subject to the
excise tax imposed by Section 4999 of the Code, Summit shall pay to him an
amount that would restore him to the same after tax position as if the excise
tax had not been imposed.

     To come within the terms of the Termination Agreement the Change in
Control of Summit must occur, or efforts designed to lead to a Change in
Control of Summit must commence, before the earlier (i) Mr. Lynch's death,
disability or retirement or (ii) October 15, 2002. The Termination Agreement
will provide for automatic


                                       28
<PAGE>

renewal on October 15, 2002 and each annual anniversary thereafter unless Mr.
Lynch is no longer employed by Summit or a subsidiary of Summit on such date,
Mr. Lynch has reached his normal retirement date or Summit has given twelve
months notice that it will not extend the Termination Agreement.

     A "Change in Control" of Summit will be defined under the Termination
Agreement to include, generally:

   o A Change in Control required to be reported under the federal securities
     laws;

   o The acquisition by any person of beneficial ownership of 25% or more of
     the combined voting power of Summit's outstanding securities then entitled
     to vote for the election of directors;

   o A change in the composition of majority membership of the Summit Board
     over any two-year period;

   o A change in ownership of Summit such that the Summit Common becomes
     subject to delisting from the NYSE;

   o The approval of the Summit Board of the sale of all or substantially all
     of the assets of Summit; or

   o The approval by the Summit Board of any merger, consolidation, issuance
     of securities or purchase of assets, the result of which would be the
     occurrence of any event described in the first four bullets above or that
     the shareholders of Summit own less than 65% of the combined voting power
     of the resulting entity.

     The definition of "Good Reason", under the Termination Agreement, will be
substantially similar to the definition of Good Reason in the Severance Plan,
but will also include a termination of employment by Mr. Lynch for any reason
other than disability or normal retirement within 30 days of the first
anniversary of an event constituting a change in control.

Prime Stock Option Plans

     As described under "THE MERGER -- Conversion of Prime Stock Options,"
Original Options outstanding at the Effective Time, whether or not then
currently exercisable, will be automatically converted into New Options, subject
to the terms of the Prime option plan and grant agreement governing the Original
Options, including terms and provisions governing exercises. The number of
shares covered by the New Options will be set by multiplying the number of
shares covered by the Original Options by the Exchange Ratio and the exercise
price per share of the New Options will be equal to the aggregate exercise price
that would have been payable upon exercise in full of the Original Option
divided by the Converted Number.

     The following table sets forth certain information relating to Original
Options held by James J. Lynch, William H. Bromley and James E. Kelly and all
directors and executive officers of Prime 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
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 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 April
8, 1999 of $38.69 as the market price for purposes of the calculation.

Stay Bonuses

     The Merger Agreement permits Prime after the Closing Date to pay "stay
bonuses" of up to $325,000 in the aggregate to employees of Prime designated by
the Prime Board (after consultation with Summit) who continue to be employees
of Prime on such payment date and who execute a release of claims against
Summit and its affiliates.


                                       29
<PAGE>

Incentive Plan Payments

     The Merger Agreement authorizes Prime to pay Prime employees up to
$720,000 in incentive compensation and bonuses under the Prime Key Executive
Incentive Plan for services rendered in 1999, provided that required
performance goals are satisfied.

Severance Pay Provision

     The Merger Agreement provides that, under certain circumstances, an
employee of Prime or a subsidiary of Prime at the Effective Time not party to
an employment, change of control, termination, severance or similar agreement,
whose employment is terminated by Summit, other than for cause, within twelve
months of the Effective Time may be entitled to receive upon execution of a
release a severance payment equal to the greater of (A) eight 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.

Legal Services


     Mr. Fred Blume, a director of Prime, is a partner in the law firm of Blank
Rome Comisky & McCauley, LLP which has performed legal services for Prime in
connection with the Merger. Blank Rome Comisky & McCauley, LLP also performs
legal services for subsidiaries of Summit, from time to time.

The Merger Agreement

     The following discussion highlights selected information from the Merger
Agreement but may not contain all of the information that is important to you.
To understand the Merger Agreement fully you should read carefully this entire
document which is included as Appendix A hereto.

Amendment


     Prime 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 Prime
shareholders unless such modification is submitted to a vote of Prime
shareholders.

Prime Covenants

     Pursuant to the Merger Agreement, Prime has agreed, among other things,
that, until the Effective Time or termination of the Merger Agreement, Prime
will advise Summit of any material adverse change in Prime's business and of
certain other circumstances, and the business of Prime and its subsidiaries
will be carried on substantially in the same manner as prior to the execution
of the Merger Agreement. Furthermore, until the Effective Time or termination
of the Merger Agreement, without the prior written consent of Summit, Prime
will not declare or pay any dividend other than a quarterly cash dividend at a
rate up to $.11 per share (which amount may be increased to $.13 per quarter if
the Effective Time has not occurred by November 30, 1999) and will refrain from
taking certain other actions, including certain actions relating to changes in
its capital stock, the incurrence of liabilities, the making of certain
expenditures, the relinquishment of certain rights, the amendment of its
articles of incorporation and bylaws and the issuance of capital stock.

     In order to ensure that Prime shareholders would be paid no more than one
dividend in each calendar quarter between the date of the Merger Agreement and
the Effective Time, Prime agreed in the Merger Agreement to coordinate with
Summit the declaration of any dividends and the setting of any dividend record
or payment dates.

     Prime also has agreed that, until termination of the Merger Agreement or
the Effective Time, neither Prime nor any of its subsidiaries nor any of the
officers or directors of Prime or its subsidiaries shall, and that Prime 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 Prime 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. "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 Prime or any of its subsidiaries, or the acquisition


                                       30
<PAGE>

of any assets (other than those permitted under the Merger Agreement) or any
securities of Prime or any of its subsidiaries. Further, Prime agreed to
immediately cease any activities, discussions, or negotiations with respect to
the foregoing. In addition, Prime has agreed to notify Summit, by telephone
call to its chief executive officer or general counsel, promptly upon receipt
of any inquiry with respect to an 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 Prime 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 Prime.

     Prime is obligated under the Merger Agreement to disclose to Summit
certain information regarding environmental conditions affecting (1) any
property now or previously owned, occupied, leased or held or managed in a
representative or fiduciary capacity (2) any property or facility of which
Prime has at any time participated in the management or may be deemed to be or
to have been an owner or operator, and (3) any real property in which Prime
holds a security interest in an amount greater than $50,000. The Merger
Agreement provides Summit with certain environmental investigative rights prior
to the Effective Time with respect to real property owned, leased or operated
by Prime on or after the date of the Merger Agreement.

Summit Covenants

     Pursuant to the Merger Agreement, Summit has agreed, among other things,
that, until the Effective Time or termination of the Merger Agreement, Summit
will advise Prime of any material adverse change in Summit's business and
certain other circumstances.

Conditions to the Merger; Termination

     The obligations of both parties to consummate the Merger are subject to
the satisfaction of certain conditions including:

   o Approval of the Merger Agreement by the requisite vote of the holders of
     Prime Common;

   o Receipt of all required regulatory approvals by Summit and Prime without
     restrictions or limitations, that, in the reasonable opinion of Summit,
     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;

   o Continued effectiveness of the registration statement;

   o The receipt by Summit and Prime of an opinion from Thomson Coburn as to
     certain federal income tax consequences of the Merger;

   o The NYSE's indication that the shares of Summit Common to be issued in
     the Merger will be listed on the NYSE, subject to official notice of
     issuance;

   o The absence of material litigation;

   o The absence of regulatory agreements relating to the parties;

   o The delivery of officers' certificates by Prime and Summit; and

   o Other customary conditions described in the Merger Agreement.

Any of these 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 shareholder and regulatory approvals.

     Either party may terminate the Merger Agreement if:

   o Prime shareholders, in a vote on the Merger Agreement at the Special
     Meeting, fail to approve the Merger Agreement by the requisite vote;

   o 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);


                                       31
<PAGE>

   o On the designated Closing Date all the conditions precedent to such
     party's obligations to close are not met due to the other party's material
     breach, or

   o The Closing is not consummated on or before the later of (1) January 3,
     2000 (provided, however, that a party does not have the termination right
     described by this clause if the failure to close by January 3, 2000 is due
     to its material breach or its failure to fulfill a condition to the
     consummation of the Merger) or, (2) the Scheduled Date, if the last
     required event for setting the Scheduled Date has occurred on or before
     January 3, 2000.

     In addition, the parties may terminate the Merger Agreement at any time by
mutual agreement. The Summit Board may terminate the Merger Agreement if the
Prime Board modifies its recommendation of the Merger Agreement or withdraws
such recommendation, or if the cost of taking necessary remedial and other
corrective actions and measures associated with certain environmental matters
exceeds $3,000,000 in the aggregate (or an unascertainable amount which cannot
be reasonably estimated to be less than such amount).

     The Prime Board may terminate the Merger Agreement if both of the
     following circumstances exist:

   o The average of the closing prices of Summit Common on the NYSE Composite
     Transactions List for the ten consecutive full trading days ending on the
     Determination Date, as defined below, (the "Summit Price") is less than
     $32.68125, and

   o The amount obtained by dividing the Summit Price by $39.375 is more than
     17% less than the amount obtained by dividing the Determination Date Index
     Price by the Starting Date Index Price, as such terms are defined below.

     In order to terminate the Merger Agreement pursuant to this provision,
Prime must give notice to Summit by 11:59 P.M. on the third business day
following the Determination Date. For purposes of this Prime right of
termination, the terms referenced above are defined as follows:

   "Determination Date" means the later of the dates that the Merger is
   approved by the Federal Reserve Board or the PDOB.

   "Index Group" means 16 bank holding companies designated in the Merger
   Agreement, the common stocks of all of which must be publicly traded and as
   to which there has not been made, since February 17, 1999 and prior to the
   Determination Date, a 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. Any such company or companies which does not satisfy any of
   the foregoing requirements shall be removed from the Index Group.
   Appropriate adjustments shall be made for stock splits, stock dividends or
   similar transactions occurring between February 17, 1999 and the
   Determination Date.

   "Determination Date Index Price" means the average of the closing prices of
   the common stock of the companies comprising the Index Group on the NYSE
   Composite Transactions List for the 10 consecutive full trading days ending
   on the Determination Date.

   "Starting Date Index Price" means the average of the closing prices of the
   common stock of the companies comprising the Index Group on the NYSE
   Composite Transactions List on February 17, 1999.

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 or if Summit terminates
because the Prime Board modifies its recommendation of the Merger Agreement or
withdraws its recommendation or because of the environmental contingency
referred to above, 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


                                       32
<PAGE>

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
Securities and Exchange Commission (the "Commission"), the Federal Reserve
Board, the PDOB and the NYSE. Each party has agreed to indemnify the other for
claims for brokerage commissions and finders fees.


Dissenters Rights

     Any Prime shareholder who objects to the Merger has the right to be paid
the fair value of all shares of Prime Common owned by such shareholder in
accordance with the provisions of Section 1930(a) and Sections 1571 through
1580 ("Subchapter 15D") of the PBCL, a copy of which is set forth in Appendix D
to this Proxy Statement-Prospectus. Prime will not give any notice of those
requirements other than as described in this Proxy Statement-Prospectus and as
required by the PBCL. The following discussion is not a complete statement of
the law relating to dissenters rights and is qualified in its entirety by
reference to Appendix D hereto. This discussion and Appendix D should be
reviewed carefully by any Prime shareholder who wishes to exercise dissenters
rights, or who wishes to reserve the right to do so, as failure to comply with
the procedures set forth in the appropriate provisions of Subchapter 15D will
result in the loss of dissenters rights.

     A holder of record of Prime Common may assert dissenters rights as to
fewer than all of the shares of Prime Common registered in the record holder's
name only if the record holder dissents with respect to all the Prime Common
beneficially owned by any one person and discloses the name and address of the
person or persons on whose behalf the holder dissents. In that event, the
record holder's rights shall be determined as if the shares as to which the
holder has dissented were registered in a name different from the other shares
owned of record by the holder. A beneficial owner of Prime Common, who is not
also the record holder of shares, may assert dissenters rights with respect to
shares held on the owner's behalf, and shall be treated as a dissenting
shareholder under the terms of Subchapter 15D if the beneficial owner submits
to Prime not later than the time of filing the Notice of Intention to Dissent
(as defined below) a written consent of the record holder. A beneficial owner
may not dissent with respect to some but less than all of the shares of Prime
Common owned by the beneficial owner, whether or not any shares are registered
in the owner's name.

     Holders of Prime Common (or beneficial owners as provided above) who
follow the procedures of Subchapter 15D will be entitled to receive from Prime
the fair value of their Prime Common immediately before the Effective Time,
taking into account all relevant factors, but excluding any appreciation or
depreciation in anticipation of the completion of the Merger Agreement. Holders
of Prime Common (or beneficial owners thereof) who elect to exercise their
dissenters rights must comply with all of the following procedures to preserve
those rights.

     Holders of Prime Common (or beneficial owners thereof) who wish to
exercise dissenters rights must file a written notice of intention to demand
the fair value of their Prime Common if the Merger Agreement is effectuated
(the "Notice of Intention to Dissent"). Holders desiring to dissent must file
the Notice of Intention to Dissent with the Corporate Secretary of Prime prior
to the vote by shareholders on the Merger Agreement; they must make no change
in their beneficial ownership of Prime Common from the date they file the
Notice of Intention to Dissent until the Effective Time; and they must refrain
from voting their Prime Common FOR the adoption of the Merger Agreement.
Neither a proxy nor a vote AGAINST the Merger Agreement will constitute the
giving of the Notice of Intention to Dissent. A proxy or a vote FOR the Merger
Agreement will cause the holder (or the beneficial owner) to lose his or her
dissenters rights under Subchapter 15D.

     If the Merger Agreement is approved by the required vote of the Prime
shareholders, Prime will mail a notice (the "Notice of Approval") to all
dissenters who filed a Notice of Intention to Dissent prior to the vote on the
Merger Agreement and who refrained from voting for the approval of the Merger
Agreement. Prime expects to mail the Notice of Approval promptly after the
Effective Time. The Notice of Approval will state where and when (the "Demand
Deadline") a demand for payment must be sent and certificates for Prime Common
must be deposited in order to obtain payment; it will supply a form for
demanding payment (the "Demand Form") which will include a request for
certification of the date on which the holder, or the person on whose behalf
the holder dissents, acquired beneficial ownership of Prime Common; and it will
be accompanied by a


                                       33
<PAGE>

copy of Subchapter 15D. Dissenters must ensure that the Demand Form and their
certificates for Prime Common are received by Prime on or before the Demand
Deadline. All mailings to Prime are at the risk of the dissenting shareholder.
Accordingly, if a shareholder desires to dissent, Prime recommends that the
Notice of Intention to Dissent, the Demand Form and the holder's stock
certificates be sent by certified mail.

     Any holder (or beneficial owner) of Prime Common who fails to file a
Notice of Intention to Dissent, fails to complete and return the Demand Form,
or fails to deposit stock certificates with Prime, each within the time periods
prescribed, will lose the holder's (or beneficial owner's) dissenters rights
under Subchapter 15D. A dissenter will retain all rights of a shareholder, or
beneficial owner, as the case may be, until those rights are modified by
effectuation of the Merger.

     Upon timely receipt of the completed Demand Form, Prime is required by the
PBCL either (i) to remit to dissenters who have returned the Notice of
Intention to Dissent and the completed Demand Form and have deposited their
certificates, each in a timely fashion, the amount Prime estimates to be the
fair value for their shares, or (ii) to give written notice that no such
remittance will be made. Prime will determine whether to make such a remittance
or to defer payment for such shares until completion of the necessary appraisal
proceedings, after giving due consideration to the number of shares, if any,
with respect to which shareholders have dissented and any objections that may
be raised with respect to the standing of the dissenting shareholder. The
remittance or notice will be accompanied by:

   o The closing balance sheet and statement of income of Prime for the fiscal
     year ended December 31, 1998, together with the latest available interim
     financial statements;

   o A statement of Prime's estimate of the fair value of the Prime Common;
     and

   o A notice of the right of the dissenter to demand payment or supplemental
     payment, as the case may be, accompanied by a copy of Subchapter 15D.

     If Prime does not remit the amount of its estimate of the fair value of
the Prime Common, it will return any certificates that have been deposited, and
may make a notation on any such certificates that a demand for payment in
accordance with Subchapter 15D has been made. If shares carrying such notation
are thereafter transferred, each new certificate issued therefor may bear a
similar notation, together with the name of the original dissenting holder or
owner of such shares. A transferee of such shares will not acquire by such
transfer any rights in Prime other than those which the original dissenter had
after making demand for payment of their fair value.

     If the dissenter believes that the amount remitted or stated is less than
the fair value of the shares he or she owns, the dissenter may send to the
Corporate Secretary of Prime the dissenter's own estimate (the "Holder's
Estimate") of the fair value of the shares as contemplated by PBCL Section
1578, which will be deemed a demand for payment of the amount of the
deficiency. If a dissenter does not file a Holder's Estimate within 30 days
after the mailing by Prime of its remittance or notice, the dissenter will be
entitled to no more than the amount stated in the notice or remitted to the
dissenter by Prime.

     If within 60 days after the Effective Time or after the timely receipt by
Prime of any Demand Form or Holder's Estimate, whichever is latest, any demands
for payment remain unsettled, Prime may file in the Court of Common Pleas of
Philadelphia County, Pennsylvania an application for relief requesting that the
fair value of the shares be determined by the court. There is no assurance that
Prime will file this application. All dissenters, wherever residing, whose
demands have not been settled will be made parties to any appraisal proceeding
commenced by Prime. The court may appoint an appraiser to receive evidence and
recommend a decision on the issue of fair value. Each dissenter who is made a
party will be entitled to recover the amount by which the fair value of his or
her shares is found to exceed the amount, if any, previously remitted, plus
interest. If Prime fails to file an application for relief, any dissenter who
has made a demand and who has not already settled his or her claim against
Prime may do so in the name of Prime at any time within 30 days after the
expiration of the 60-day period. If a dissenter does not file an application
within the 30-day period, each dissenter entitled to file an application shall
be paid Prime's estimate of the fair value of the shares and no more, and may
bring an action to recover any amount not previously remitted.


     The cost and expenses of the court proceedings, including the reasonable
compensation and expenses of the appraiser appointed by the court, will be
determined by the court and assessed against Prime, except that any


                                       34
<PAGE>

part of the costs and expenses may be apportioned and assessed as the court
deems appropriate against all or some of the dissenters who are parties and
whose action in demanding supplemental payment the court finds to be dilatory,
arbitrary or in bad faith. Fees and expenses of counsel and of experts of the
respective parties may be assessed as the court deems appropriate against
Prime, and in favor of any or all dissenters, if Prime fails to comply
substantially with the requirements of Subchapter 15D. These fees and expenses
may be assessed against either Prime or a dissenter, if the court finds that
the party against whom the fees and expenses are assessed acted in bad faith or
in a dilatory or arbitrary manner. If the court finds that the services of
counsel for any dissenter were of substantial benefit to other dissenters
similarly situated and should not be assessed against Prime, it may award that
counsel reasonable fees to be paid out of the amounts awarded to the dissenters
who were benefited.

     Under the PBCL, a shareholder of Prime has no right to obtain, in the
absence of fraud or fundamental unfairness, an injunction against the Merger,
nor any right to valuation and payment of the fair value of the holder's shares
because of the Merger, except to the extent provided by the dissenters rights
provisions of Subchapter 15D. The PBCL also provides that absent fraud or
fundamental unfairness, the rights and remedies provided by Subchapter 15D are
exclusive. This Proxy Statement-Prospectus constitutes the notice of a proposed
corporate action which would give rise to dissenters rights as required under
PBCL Section 1571(d).


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 treated as a
purchase. Under the purchase method of accounting, the amount by which the
purchase price paid by Summit exceeds the fair value of the net assets acquired
will be treated as goodwill. Intangibles recorded in the transaction will be
amortized over a period not to exceed 20 years.


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 consequences of the Merger to Prime shareholders 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 Prime shareholders 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 Prime
shareholders 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 Prime
Common pursuant to the exercise of employee stock options or otherwise as
compensation, and persons who hold their Prime 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 Prime shareholder is urged to consult his or her
own tax advisor to determine the specific tax consequences of the Merger to
such shareholder. The discussion assumes that shares of Prime Common are held
as capital assets (within the meaning of Section 1221 of the Code) at the
Effective Time.

     Prime 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:

   o Prime shareholders will recognize no gain or loss as a result of the
     exchange of their Prime 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.


                                       35
<PAGE>

   o The aggregate adjusted tax basis of the shares of Summit Common received
     by each Prime shareholder in the Merger (including any fractional share of
     Summit Common deemed to be received, as described in bullet 4 below) will
     be equal to the aggregate adjusted tax basis of the shares of Prime Common
     surrendered.

   o The holding period of the shares of Summit Common received by each Prime
     shareholder in the Merger (including any fractional share of Summit Common
     deemed to be received, as described in bullet 4 below) will include the
     holding period of the shares of Prime Common exchanged therefor.

   o A Prime shareholder 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 shareholder 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
and Prime. 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 Prime 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 Prime shareholders and does not take into account the
particular facts and circumstances of each Prime shareholder's tax status and
attributes. As a result, the federal income tax consequences addressed in the
foregoing discussions may not apply to each Prime shareholder. Accordingly,
each Prime shareholder 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 Prime Common are
converted at the Effective Time will be freely transferable under the
Securities Act except for shares issued to any shareholder who may be deemed to
be an "affiliate" of Prime for purposes of Rule 145 under the Securities Act of
1933, as amended (the "Securities Act") as of the date of the Special Meeting.
Affiliates of Prime 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. Persons who may be deemed to
be affiliates of Prime generally include individuals or entities that control,
are controlled by or are under common control with Prime and may include
executive officers and directors of Prime as well as principal shareholders of
Prime.

     Prime agreed in the Merger Agreement to use its best efforts to cause each
director, executive officer and other person deemed in the opinion of Prime's
counsel to be affiliates of Prime to enter into an agreement with Summit
providing that such persons agree to be bound by the restrictions of Rule 145.


Differences in Shareholders' Rights

     The rights of Prime shareholders, which are determined by the PBCL, and
the Articles of Incorporation and Bylaws of Prime, differ from the rights of
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 laws of Pennsylvania, the state of Prime's


                                       36
<PAGE>

incorporation, and the corporation law of New Jersey, the state of Summit's
incorporation. The remaining differences in shareholders' rights are
attributable to differences between the Articles of Incorporation and Bylaws of
Prime and the Restated Certificate of Incorporation and By-Laws of Summit.
Certain of the rights of Prime shareholders described below which are provided
by Pennsylvania corporation law or contained in the Articles of Incorporation
or Bylaws of Prime and which are not provided by New Jersey corporation law or
contained in the Restated Certificate of Incorporation or By-Laws of Summit may
be deemed to have an anti-takeover effect and will not be available to Prime
shareholders as Summit shareholders; however, certain rights provided for by
New Jersey corporation law or the Restated Certificate of Incorporation or
By-Laws of Summit also may be deemed to have an anti-takeover effect and will
be applicable to Prime shareholders 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 Pennsylvania and New Jersey and the governing documents
of Prime and Summit referred to above.


Comparison of Certificate or Articles of Incorporation and By-Laws


Classified Board and Related Provisions


     Prime. The Articles of Incorporation and Bylaws of Prime provide that the
Prime Board shall consist of not less than seven nor more than fifteen
directors and divides the Prime Board into three classes, with each class
serving a term of three years. Directors are elected by a plurality of votes
cast. Presently there are twelve directors of Prime. Holders of Prime Common
may not cumulate their votes in elections of directors.


     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 seven directors in
Class I, six directors in Class II and five directors in Class III. 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 the classified board and related 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


     Prime. Prime's Articles of Incorporation provide that a special meeting of
shareholders may be called only by the President, the Chairman of the Board, or
a majority of the Prime Board. The Articles of Incorporation and Bylaws of
Prime do not authorize shareholder action by partial written consent and the
PBCL prohibits such action without express authorization in the Bylaws. The
Articles of Incorporation and Bylaws of Prime do not prohibit action by
unanimous consent and therefore such actions are permitted under the PBCL.


     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 Summit 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


                                       37
<PAGE>

to amend, alter, repeal or take any action inconsistent with this requirement.
Under Summit's 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.

Summit Shareholder Rights Plan

     Summit. 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, one one
hundred-fiftieth of a share of a new series of Preferred Stock, designated the
Series R Preferred Stock, at $60 per one one hundred-fiftieth share ("exercise
price"), with full shares having rights per share equal to 150 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 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 partial or two-tiered acquisition
proposals.

     Prime. Prime has not adopted a shareholders rights plan.


Nominations to the Board, Shareholder Proposals and Conduct of Meeting

     Prime. Prime's Bylaws provide that any shareholder wishing to nominate a
candidate for election to the Prime Board or to bring any other business before
a meeting of shareholders must give notice of such nomination or item of
business to Prime in writing received by Prime at its executive offices not
less than 30 days nor more than 90 days prior to the meeting; provided,
however, that if less than 40 days notice or prior public disclosure of the
meeting is given or made to shareholders, such notice, to be timely, must be
received no later than the 10th day following such notice or public disclosure.
 

     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
shareholder 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

     Prime. Prime's Articles of Incorporation may be amended only as proposed
by the Board of Directors, upon the affirmative vote of a majority of the votes
cast by the shareholders entitled to vote thereon at a duly called meeting.
However, amendments to Article 7 of Prime's Articles of Incorporation (relating
to approval of acquisitions of control and offers to acquire control) may only
be made by the affirmative vote of at least two-thirds of the outstanding
shares that are entitled to vote generally in the election of directors;
amendments to

                                       38
<PAGE>

Article 8 of Prime's Articles of Incorporation (relating to supermajority
voting requirements applicable to certain business combinations) may only be
made by the affirmative vote of shareholders holding at least 75% of
outstanding shares at a duly called meeting; amendments to Article 9
(anti-greenmail provision) may only be made by the affirmative vote of the
holders of at least a majority of the total number of outstanding shares that
are entitled to vote generally in the election of directors; and amendments to
Article 11 (relating to amending the Bylaws) may only be made by the
affirmative vote of at least two-thirds of the votes cast by all shareholders
at a duly called meeting. Prime's Bylaws may be amended at a meeting called for
such purpose upon the affirmative vote of two-thirds of the directors then in
office or two-thirds of the outstanding voting shares at a duly called meeting.
Bylaws made by the Prime Board may be changed by vote of Prime's shareholders.

     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, after board approval by the affirmative vote of a
majority of the votes cast. The By-Laws of Summit provide for amendments upon
two-thirds 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.

Supermajority Vote on Certain Transactions

     Prime.  The Articles of Incorporation of Prime prohibit the acquisition of
control of Prime, (which means the sole or shared acquisition of 10% or more of
the voting power of Prime) unless the acquisition of control was approved by at
least two-thirds of the then current directors or at least two-thirds of the
outstanding voting securities of Prime. Furthermore, as long as Prime Common
continues to be traded on the Nasdaq or a national securities exchange, no
offer to acquire sole or shared control of 10% or more of the voting power of
Prime Common may be made, unless it has received either the prior approval of
at least two-thirds of the directors then in office or the prior approval of
certain regulatory authorities.

     The Articles of Incorporation of Prime also require that certain mergers,
consolidations, asset transfers, transfers of voting securities of Prime or of
any of its subsidiaries, proposals for liquidation or dissolution, or certain
other transactions involving interested shareholders or their affiliates (i.e.,
a shareholder holding directly or indirectly more than 10% of the voting power
of the outstanding Prime voting securities) will require both the affirmative
vote of 75% of all eligible voting power and over half of the voting power
excluding the interested shareholders of Prime, unless the transaction has
received the affirmative vote of a majority of certain disinterested directors
or the value of the consideration to be received by shareholders of Prime meets
certain specified valuation tests. The Articles of Incorporation also contain a
prohibition against the payment of greenmail to shareholders.

     Summit. Summit's Restated Certificate of Incorporation does not contain any
supermajority voting provisions with respect to change of control transactions.
 

Removal of Directors

     Prime. Under Prime's Bylaws, except in the event of a court order or legal
incompetency or imprisonment for a term of more than one year, any individual
director may be removed only for cause by the affirmative vote of the holders
of a majority of shares entitled to vote at a duly constituted meeting called
for such purpose.

     Summit. The Summit Restated Certificate of Incorporation contains no
specific provisions with respect to removal of directors (other than for
directors elected by preferred shareholders). Under the New Jersey Business
Corporation Act, with respect to a classified board, 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

     Prime. The Articles of Incorporation of Prime authorize the issuance of
13,000,000 shares of Prime Common and 2,000,000 shares of preferred stock, par
value $1.00 per share ("Prime Preferred"). The Prime Board


                                       39
<PAGE>

has the power to set the rights, preferences, privileges and designations with
respect to each class or series of Prime Preferred and to issue such Prime
Preferred without shareholder approval. As of March 31, 1999, there were
11,001,806 shares of Prime Common outstanding and no shares of Prime Preferred
outstanding. Prime's shareholders do not have preemptive rights.


     Summit. The Restated Certificate of Incorporation of Summit authorizes the
issuance of 390,000,000 shares of Summit Common and 6,000,000 shares of
preferred stock, no par value. As of March 31, 1999, there were approximately
172,692,000 shares of Summit Common outstanding and 4,901,000 shares of Summit
Common held in treasury and 1,500,000 shares of Summit Series R Preferred
reserved for issuance under the shareholder rights plan of Summit. The Restated
Certificate of Incorporation of Summit and the New Jersey Business Corporation
Act ("NJBCA") authorize the Summit Board to amend the Restated Certificate of
Incorporation without shareholder 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


     Prime. Article IX of Prime's Bylaws provides that Prime shall indemnify
any person involved or threatened to be involved in any action, suit or
proceeding by reason of being an officer, director, employee or agent of the
corporation against expenses, judgments, fines, penalties and amounts paid in
settlement in connection with such actions if such person acted in good faith
and in a manner he or she reasonably believed to be in the best interests of
the corporation. Article IX of Prime's Bylaws also provide that the directors
of Prime shall not be personally liable for monetary damages for any action
taken or failure to take any action unless the director breached or failed to
perform his or her fiduciary duties under Pennsylvania law and the breach or
failure constituted self-dealing, willful misconduct or recklessness. The
limitation of liability does not apply to liabilities for taxes or violation of
any criminal statute.


     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 owned 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


     Dissenters Rights in Merger or Consolidation. Under the NJBCA, 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 that 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.


     The PBCL provides dissenters rights of appraisal to shareholders of a
Pennsylvania corporation, such as Prime, in the event of a merger or
consolidation or similar transaction, unless the shares of the corporation
being acquired are listed on a national securities exchange or held of record
by more than 2,000 shareholders; provided, however, that such exception does
not apply in situations where shares are not converted solely into shares of
the acquiring or surviving corporation or solely into such shares and cash in
lieu of fractional shares. See "THE MERGER -- Dissenters Rights."

     Dissenters Rights Relating to Disposition of Assets. Under the NJBCA, 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. The Pennsylvania dissenters rights
statute discussed in the preceding paragraph also applies in the event of the
sale of substantially all of the assets of a corporation, other than sales in
the usual course of business, certain liquidations or sales pursuant to a court
order.

     Class Voting on Merger or Consolidation. Under the NJBCA, any class or
series of shares shall be entitled to vote as a class if the plan of merger or
consolidation contains any provisions that, if contained in a proposed charter
amendment, would entitle the class or series to vote as a class on the
amendment. The PBCL contains a similar provision on class voting on a plan of
merger.

     Source of Dividends. Under the NJBCA, 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. The
PBCL permits the payment of dividends unless (1) the corporation would be
unable to pay its debts as they become due in the ordinary course of business
or (2) the total assets of the corporation would be less than the sum of its
liabilities plus the amount that would be needed upon dissolution to pay the
holders of shares having a liquidation preference.

     Shareholder Approval of Mergers and Consolidations. While shareholder
approval of a merger or consolidation is generally required under both the
NJBCA and the PBCL, the NJBCA 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.

     Under both the NJBCA and PBCL, unless otherwise provided in the
corporation's certificate or articles of incorporation, a merger requiring
shareholder approval must be approved by the majority of the votes cast by
shareholders entitled to vote thereon.

     Under the PBCL, if a shareholder of a registered corporation (such as
Prime) is a party to a sale of assets transaction, share exchange, merger or
consolidation involving the corporation or a subsidiary, or if a shareholder is
to receive a disproportionate amount of the shares or other securities of any
corporation surviving or resulting from a plan of division, or is to be treated
differently in a corporate dissolution from other shareholders of the same
class, or is to have a materially increased percentage of voting or economic
share interest in the corporation relative to substantially all other
shareholders as a result of a reclassification, then approval must be obtained
of the shareholders entitled to cast at least a majority of the votes which all
shareholders other than the interested shareholder are entitled to cast with
respect to the transaction without counting the votes of the interested
shareholder (and certain affiliated and associated persons). Such additional
shareholder approval is not required if the consideration to be received by the
other shareholders in such transaction for shares of any class is not less than
the highest amount paid by the interested shareholder in acquiring shares of
the same class, or if the proposed transaction is approved by a majority of the
board of directors other than certain directors affiliated or associated with,
or nominated by, the interested shareholder.

     Under the PBCL, an articles amendment or plan of reclassification, merger,
consolidation, exchange, asset transfer, division or conversion that provides
mandatory special treatment for the shares of a class held by particular
shareholders or groups of stockholders that differs materially from the
treatment accorded other shareholders or groups of shareholders holding shares
of the same class must be approved by each group of holders


                                       41
<PAGE>

of any outstanding shares of a class who are to receive the same special
treatment under the amendment or plan, voting as a special class in respect of
the plan, regardless of any limitations stated in the articles or bylaws on the
voting rights of any class or series. At the option of the corporation's board
of directors, the approval of such special treatment by any such affected group
may be omitted, but in such event the holder of any outstanding shares of the
special class so denied voting rights will be entitled to dissenters rights.

     Shareholder Approval of Asset Sales. Under both the NJBCA and the PBCL, a
sale of all or substantially all of a corporation's assets outside 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. The Restated Certificate of Incorporation of Summit provides that
the Summit Board may sell all the rights, franchises and property of Summit as
an entirety with the approval of two-thirds of the outstanding shares.

     Power to Adopt, Amend or Repeal By-Laws. Under the NJBCA, 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 the PBCL, unless otherwise provided in the
corporation's articles or bylaws, the bylaws may be amended by a majority of
votes cast by shareholders or by the majority of the Board of Directors, unless
the matter is required by statute to be submitted to the shareholders.
Amendments to the bylaws of a Pennsylvania corporation adopted by the board of
directors are subject to the power of shareholders to change such action.

     Action by Shareholders by Written Consent in Lieu of a Meeting. Under the
NJBCA, except as otherwise provided in a certificate of incorporation, any
action (other than the election of directors or a merger) 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. The annual election of directors, if not conducted at a
shareholders' meeting, may only be effected by unanimous written consent. Under
the NJBCA, a shareholder vote on a plan of merger, consolidation or sale of
substantially all of the assets of the corporation, if not conducted at a
shareholders' meeting, may only be effected by either: (i) unanimous written
consent of all shareholders entitled to vote on the matter with advance notice
to any other shareholders, or (ii) unless otherwise provided in the
corporation's certificate of incorporation, written consent of shareholders who
would have been entitled to cast the minimum number of votes necessary to
authorize such action at a meeting, together with advance notice to all other
shareholders. As previously discussed, Summit's Restated Certificate of
Incorporation permits action by written consent only where the consent is
unanimous. Under the PBCL shareholders may take action by unanimous written
consent, unless otherwise restricted by the corporation's bylaws, but may not
take action by less than unanimous written consent unless specifically
permitted by such corporation's articles or bylaws.

     Removal of Directors. Under the NJBCA, 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 (such as
Summit) may not remove a director except for cause. Under the PBCL, any
director or the entire board of directors may be removed, with or without
cause, by the vote of the shareholders entitled to elect directors, provided
that, unless otherwise provided in the corporation's articles, if the board is
divided into classes, as is the Prime Board, directors may only be removed for
cause.

     Special Meetings of Shareholders. Under the NJBCA, 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 the PBCL,
shareholders may not call special meetings of shareholders unless the
shareholder is an "interested shareholder" and the meeting relates to certain
business combinations.

     DeFacto Merger. Under the NJBCA, shareholders have the same voting and
dissenters' rights as if they were shareholders of a surviving corporation in a
merger, if (1) voting shares outstanding or issuable after the


                                       42
<PAGE>

transaction exceed by more than 40% of the voting shares outstanding before the
transaction or (2) sharesentitled to participate without limitation in
distributions outstanding or issuable after the transaction exceed by more than
40% such shares outstanding before the transaction. The PBCL does not contain a
comparable provision.

     Shareholders' Derivative Actions. The NJBCA contains certain provisions
that have the effect of discouraging derivative actions. Specifically, the
NJBCA 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. The PBCL
contains a provision entitling a corporation involved in a derivative action
instituted by holders of less than 5% of the corporation's outstanding shares
(unless such shares have value of greater than $200,000) to require the
plaintiffs to give security for reasonable expenses (including attorney's fees)
that the corporation may incur or become liable for in the case of mandatory
indemnification, to which security the corporation may have recourse in such
amount as a court may determine.

     Inspection of Books and Records. Under the NJBCA, 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 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. Furthermore, 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 the PBCL, every shareholder
has a right, upon written verified demand stating the purpose thereof, to
examine, in person or by agent or attorney, the share register, books and
records of account, and records of the proceedings of the incorporators,
shareholders and directors, and to make copies of extracts therefrom. The
shareholder's purpose for requesting access must be reasonably related to the
interest of the person as a shareholder. Shareholders do not have the right to
inspect corporate documents for an improper purpose; nor do they have the right
to inspect documents which do not fall within the narrow categories listed in
the PBCL or the corporation's bylaws. The scope of records to which a
shareholder might otherwise have access may be further limited by
considerations of privacy, privilege and confidentiality.

     In addition, the officer or agent having charge of the transfer books for
shares of the corporation is required to prepare a complete list of the
shareholders entitled to vote at any meeting of shareholders, arranged in
alphabetical order, with the address of and the number of shares held by each.
The list is required to be produced and kept open at the time and place of the
meeting and shall be subject to the inspection of any shareholder during the
meeting.

     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 after the person becomes an interested stockholder
unless the corporation's board approved the transaction prior to the
stockholder becoming an interested stockholder, and after such five-year period
a business combination may only be effected if the transaction was approved by
the corporation's board of directors 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 interested stockholder 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


                                       43
<PAGE>

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.


     Chapter 25 of the PBCL contains certain shareholder protection provisions
which apply to registered corporations, such as Prime, unless the corporation
elects not to be governed by the provisions. Prime elected in its Articles of
Incorporation only to have Chapter 25F and Section 2538, described below, be
applicable to it.


     Chapter 25E provides that in the event a shareholder becomes a controlling
shareholder of a registered corporation by, individually or as part of a group,
directly or indirectly, acquiring 20% or more of the share voting power of the
corporation, then any remaining shareholders who object to the transaction are
entitled to compel the acquirer to purchase all remaining shares for their fair
market value in cash, including a pro-rata share of any control premium enjoyed
by the controlling shareholder, although non-controlling shareholders are not
precluded from selling their shares to the controlling shareholder at any other
price. There are certain exceptions to the statutory determination of
acquisition of control relating, among other circumstances, to share
acquisitions by bequest or in the course of fulfilling duties as an agent,
broker, nominee, trustee, or similar third-party. The controlling shareholder
must give notice to every voting shareholder of record of the corporation when
a control transaction has occurred. In the event that the controlling
shareholder and any dissenting shareholders cannot agree on the fair market
value of the shares within the proper statutory time period, or if the
controlling shareholder fails to provide proper statutory notice of a control
transaction, then the statute also provides for a court-supervised valuation
procedure and appraiser, of which dissenting shareholders may avail themselves.
 


     Chapter 25F generally prohibits business combinations for a period of five
years with a 20% or more shareholder unless all disinterested directors
approve. Subject to certain exceptions, any investor who acquires 20% or more
of the stock of a Pennsylvania corporation may not engage in any "business
combination" with the corporation for a five-year period. In addition, shares
which are issuable under any agreement or upon exercise of conversion or option
rights or with respect to shares acquired in a stock split, stock dividend or
recapitalization are not included as owned by an interested shareholder for
purposes of calculating the 20% threshold.


     The PBCL defines a "business combination" to include a merger of the
corporation with the interested shareholder, a mortgage or sale of assets
having a market value of ten percent or more of the aggregate market value of
the assets or stock of the corporation to the interested shareholder, the
liquidation of the corporation as proposed by the interested shareholder, an
issuance of shares equal to five percent or more of the market value of all
outstanding shares of the corporation, and certain other transactions which may
disproportionately benefit the interested shareholder. The PBCL also includes
certain lease and mortgage transactions in the definition of business
combinations.


     Under the PBCL, a "business combination" with an interested shareholder
may occur if any of the following conditions are met: (1) prior to the
acquisition of 20% or more of the outstanding stock, the board of directors
approves such acquisition of stock or the "business combination;" (2) following
the acquisition of 20% or more of the outstanding stock, all holders of common
stock consent; or (3) if the interested shareholder owns 80% of the
corporation's voting stock and a majority of disinterested shareholders consent
to the proposed "business combination" at a meeting called no earlier than
three months after the acquisition of 20% or more of the outstanding stock and
all shareholders receive a price for their shares in accourdance with a "fair
price" valuation procedure provided in the PBCL. After five years, any
"business combination" must be approved by holders of a majority of shares
other than those held by the interested shareholder, or all shareholders other
than the interested shareholder must receive a price for their shares in
accordance with a "fair price" valuation procedure.


     Chapter 25G provides that a shareholder loses his voting rights in a
control share acquisition, i.e. the purchase of more than 20% of the
corporation's stock, unless and until the remaining shareholders of the
corporation vote to restore voting rights after a detailed information
statement is provided to all shareholders, and the corporation is also provided
a right to redeem the stock for a period of two years.


                                       44
<PAGE>

     Chapter 25H provides for the disgorgement of greenmail profits, i.e. any
profits earned over the original purchase price during a certain period of
time. Greenmail is the practice of a company's repurchasing of the shares at a
premium over market from a potential acquiror in order to stop or eliminate the
threat of an acquisition by the potential acquiror.


     Section 2538 concerns transactions involving interested shareholders,
which are defined for purposes of Section 2538, to be shareholders that are a
party to a transaction, or that are treated differently from other shareholders
in a transaction, or persons acting in concert with, under common control with,
or controlling, directly or indirectly, the interested shareholder, with the
exception of certain agents and other such third parties. Section 2538 requires
the affirmative vote of a majority of all shareholders, excluding shares held
by an interested shareholder, to approve certain fundamental transactions such
as a merger, consolidation, share exchange, sale of a substantial portion of
the corporation's assets, division, voluntary dissolution, winding-up, or
reclassification of the corporation. However, these shareholder approval
provisions do not apply (1) when the transaction has been approved by a
majority of the board of directors, excluding directors who have a material
equity interest in the interested shareholder or who were nominated for
election by the interested shareholder and were first elected to the board
within 24 months of the transaction; (2) if the consideration to be received by
shareholders of any class in the transaction is at least equal to the highest
amount paid by the interested shareholder in acquiring shares of the same
class; or (3) if the plan of merger or consolidation relating to the
transaction does not require the approval of the corporation's shareholders
under PBCL Section 1924(b)(1)(ii) because immediately prior to the adoption of
the plan and continously until the effective date of the transaction another
party to the merger or consolidation directly or indirectly owns at least 80%
of the outstanding shares of each class of the corporation. These provisions
are cumulative and apply in addition to any other approvals and procedures
required by state law or the articles of incorporation and bylaws of the
corporation.


     Under the NJBCA, 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: (1) the effects of the action on the corporation's employees,
suppliers, creditors and customers; (2) the effects of the action on the
community in which the corporation operates; and (3) the long-term as well as
the short-term interest 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 specifically covered by this
provision of the NJBCA.


     The PBCL contains a similar "other constituency" provision with regard to
mergers, sales of assets and other business combinations, which (1) gives the
Prime Board the authority to weigh (in addition to consideration of employees,
suppliers, customers and creditors of the corporation, the communities in which
the corporation is located and other pertinent factors) the short- and
long-term interests of the corporation and the possibility that they may be
best served by the independence of the corporation, and the resources, intent
and past and potential conduct of the prospective acquiror, (2) relieves the
Prime Board from any duty to regard the shareholder interest as dominant or
controlling, (3) explicitly gives the Prime Board the discretion to refuse to
redeem a shareholder rights plan or to refuse to take certain specified actions
with respect to potential acquisitions of control of the corporation, (4)
declares actions by directors with respect to a takeover bid to be subject to
the same standard of conduct for directors that is applicable to all other
conduct, and (5) establishes a presumption that actions with respect to a
takeover bid by the "disinterested directors" (a term defined to include
essentially all directors except certain officers and persons associated with
the prospective acquiror) are lawful unless it is proved under a clear and
convincing evidence standard that the director did not act in good faith after
reasonable investigation.


     Indemnification. Under the NJBCA, a corporation may indemnify any person
who is or was a director, officer, trustee, 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 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,


                                       45
<PAGE>

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. The NJBCA 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 indemnify such person under the statute.


     The PBCL permits a corporation, and Prime's Bylaws require Prime, to
indemnify any person involved in a third-party action by reason of his being an
officer or director of the corporation, against expenses, judgments, fines and
settlement amounts paid in the third-party action (and against expenses
incurred in any derivative action), if the person acted in good faith and
reasonably believed that his actions were in or not opposed to the best
interests of the corporation and, with respect to any criminal proceeding, had
no reasonable cause to believe that his conduct was unlawful. In general, no
indemnification for expenses in derivative actions is permitted under the PBCL
in situations in which the person has been adjudged liable to the corporation,
unless a court finds him entitled to indemnification. If, however, the person
has been successful in defending a third-party or derivative action,
indemnification for expenses incurred is mandatory.


     The PBCL provisions for indemnification are non-exclusive with respect to
any other rights, such as contractural rights, or rights under a bylaw or
pursuant to a vote of shareholders or disinterested directors, to which a
person seeking indemnification may be entitled. The Prime Bylaws do not contain
such a provision. The PBCL expressly permits such contractual or other rights
to provide for indemnification against judgments and settlements paid in a
derivative or other action unless a court determines that the act or omission
giving rise to the claim for indemnification constituted willful misconduct or
recklessness.


     Both the NJBCA and the PBCL permit advancement of expenses.


     Limitation of Director and Officer Liability. The NJBCA 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 (1) the opinion of counsel for the
corporation, (2) 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, (3) 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 (4) written
reports of committees of the board. The PBCL contains a similar provision which
provides that members of a board of directors are entitled to 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.


     The NJBCA further provides that the certificate or incorporation of
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 (1) in breach of the director's or
officer's duty of loyalty to the corporation or its shareholders, (2) not in


                                       46
<PAGE>

good faith or involving a knowing violation of law, or (3) resulting in receipt
by such person of an improper personal benefit. With respect to the foregoing
provisions, the NJBCA 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.

     Under the PBCL, the articles of incorporation or bylaws of a Pennsylvania
corporation may provide that a director or officer shall not be personally
liable, as such, for monetary damages for any action taken, or any failure to
take any action, unless the director or officer has breached or failed to
perform the duties of his or her office as set forth under the PBCL and the
breach or failure to perform constitutes self-dealing, willful misconduct or
recklessness. This limitation does not apply to the responsibility or liability
of a director or officer pursuant to any criminal statute or the liability of a
director of officer for the payment of taxes. The Bylaws of Prime contain such
a provision.

                                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 several
active non-bank subsidiaries. At March 31, 1999, Summit had total consolidated
assets of $33.5 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
(New Jersey) is Summit's largest bank subsidiary, accounting for approximately
89% of Summit's total consolidated assets at March 31, 1999. Summit's non-bank
subsidiaries engage primarily in securities products and services, life,
health, property and casualty insurance products and services, venture capital
investment, commercial finance lending, lease financing, asset-based lending,
letter of credit issuance, data processing and reinsuring credit life and
disability insurance policies related to consumer loans made by the bank
subsidiaries.

     As of March 31, 1999 the bank subsidiaries operated 455 banking offices

     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 nonbank 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 both Summit Bank
(New Jersey) and Summit Bank (Pennsylvania), 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. Summit Bank (Connecticut), as
a Connecticut chartered bank, is subject to a similar restriction. Further,
Summit Bank (New Jersey), as a New Jersey state-chartered bank, may declare a
dividend only if, after payment thereof, its capital stock would be unimpaired
and its surplus would equal at least 50 percent of its capital stock or its
surplus would not be reduced and Summit Bank (Pennsylvania), as a
Pennsylvania-chartered bank, may declare and pay a dividend only out of
accumulated net earnings and only if it has surplus at least equal to its
capital and its surplus would not be reduced by payment of the proposed
dividend. In addition, under the Federal Deposit Insurance Corporation
Improvement Act all institutions are prohibited from paying dividends if after
doing so an institution would be undercapitalized. Summit may not pay dividends
to its shareholders if after paying any dividends it would be unable to pay its
debts as they become due in the usual course of business or its total assets
would be less than its total liabilities. At March 31, 1999, the total
undistributed net assets of Summit's subsidiary banks were $2.6 billion of
which $81.9 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 390,000,000 shares of Summit
Common and 6,000,000 shares of Preferred Stock, without par value ("Summit
Preferred"). As of March 31, 1999 there were approximately 172,692,000 shares
of Summit Common outstanding, 4,901,000 shares of Summit Common held in
treasury, 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), and no shares of Summit Preferred
outstanding. 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 shareholder 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 (New Jersey)
is the co-transfer agent.


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, 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 one-hundred and fiftieth 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: (i)
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 (ii) ten business days (or such later date as
the


                                       49
<PAGE>

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 to receive,
upon the exercise of the Right, common stock of the acquiror having a value
equal to two times the exercise price of the Right.

     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 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.


                              PRIME BANCORP, INC.


Description of Business

     Prime was incorporated under the laws of the Commonwealth of Pennsylvania
in 1996 for the purpose of converting its predecessor from a Delaware
corporation to a Pennsylvania corporation, while at the same time effecting the
merger with First Sterling Bancorp, Inc., then a privately held bank holding
company. Prime is regulated as a bank holding company. Prior to October 1,
1997, Prime's principal subsidiaries were Prime Bank, a savings bank and First
Sterling Bank, a commercial bank. On October 1, 1997, the merger of the two
banks was completed with the surviving entity taking the name Prime Bank, which
is a Pennsylvania chartered commercial bank and a member of the Federal Reserve
System. Prime's corporate headquarters is in Fort Washington, Pennsylvania at
7111 Valley Green Road, Fort Washington, PA 19034-2209 (215-836-2400).

     The principal business of Prime Bank consists of attracting deposits and
obtaining borrowings, and converting those deposits and borrowings into various
types of loans and investments. Prime Bank's loan products include commercial
loans, real estate loans, consumer loans and consumer and residential
mortgages. Deposits are generated along five (5) major lines: checking,
savings, retail certificates of deposit, jumbo certificates of deposit and
commercial cash management.

     As of April 30, 1999, Prime Bank operated through twenty-four (24)
branches in the Philadelphia metropolitan area. Prime Bank also has received
approval from the Pennsylvania Department of Banking to open three new
branches. It is anticipated that these new branches will be opened in the third
quarter of 1999 as Summit Bank (Pennsylvania) branches after completion of the
Merger.

     The statutory headquarters of Prime Bank is located in northeast
Philadelphia, Pennsylvania. Prime Bank has eight (8) full service branches in
Philadelphia, five (5) in Bucks County, Pennsylvania, eight (8) in Montgomery
County, Pennsylvania, two (2) in Delaware County, Pennsylvania and one (1) in
Chester County, Pennsylvania.


Recent Developments

     On April 8, 1999, Prime Bank announced the signing of a lease for a new
branch bank location at 1430 Walnut Street, Philadelphia, Pennsylvania. Subject
to the approval of the PDOB, this center city branch will be opened in the
fourth quarter of 1999 and represents a key commitment to the center city
business community with its significant demand for commercial lending
expertise.


                                       50
<PAGE>

     Prime Bank has entered into a letter of understanding to sell its credit
card portfolio to MBNA. The transaction is expected to be completed in the third
quarter of 1999. Prime Bank's credit card portfolio amounts to approximately $10
million.


                      DESCRIPTION OF PRIME CAPITAL STOCK



General


     Prime has the authority to issue 13,000,000 shares of Prime Common        ,
and 2,000,000 shares of Prime Preferred. As of March 31, 1999, 11,001,806 shares
of Prime Common were issued and outstanding. No shares of Prime Preferred are
currently issued or outstanding.


     The following summary does not purport to be complete and is subject in
all respects to the applicable provisions of the PBCL, and the Articles of
Incorporation and Bylaws of Prime.


Common Stock

     Voting Rights. Each holder of Prime Common has one vote on matters
presented for consideration by the shareholders for each share held. There are
no cumulative voting rights in the election of directors. The Prime Board has
the power to designate or issue one or more series of Prime Preferred with
rights, preferences, privileges and designations, including voting rights,
which could adversely affect the voting rights of the holders of the Prime
Common. Super-majority voting provisions apply in certain situations. See "THE
MERGER -- Differences in Shareholders' Rights."

     Dividends. Each holder of Prime Common is entitled to share ratably in
dividends out of funds legally available therefor, when and as declared by the
Prime Board, after full cumulative dividends on any class or series of Prime
Preferred ranking superior as to dividends to the Prime Common have been paid
or declared and funds sufficient for the payment thereof set apart, and after
the payment of the full amount of sinking fund, retirement fund, or other
retirement payments, if any, to which holders of shares of the Prime Preferred
may be entitled in preference to the Prime Common.

     It is Prime's current policy to pay quarterly cash dividends. Future cash
dividends will be subject to determination and declaration by the Prime Board,
which will take into account Prime's financial condition, results of operations,
industry standards, economic conditions, and other factors including regulatory
and tax considerations. Currently, Prime relies on the payment of dividends by
Prime Bank in order to generate cash and income sufficient to pay dividends to
its shareholders. The amount of dividends that may be declared or paid by Prime
Bank are subject to certain regulatory restrictions. For example, Pennsylvania
chartered commercial banks may not declare or pay cash dividends on their stock
if the effect of paying the dividend would be to cause the bank's net worth to
be reduced below (i) the amount, if any, required for the liquidation account,
or (ii) the net worth requirements imposed by applicable bank regulatory
authorities.


     Preemptive Rights. The holders of Prime Common have no preemptive rights
to acquire any new or additional unissued shares or treasury shares of the
capital stock of Prime.


     Liquidation. In the event of a liquidation, dissolution or winding up of
Prime, whether voluntary or involuntary, the holders of the Prime Common are
entitled to share ratably in any assets or funds of Prime that are available
for distribution to its shareholders after satisfying its liabilities (or after
adequate provision is made therefor) and after any preferences on any
outstanding Prime Preferred.


Preferred Stock


     The Prime Board has the authority, without further action by the holders
of the outstanding shares of Prime Common, to issue shares of Prime Preferred
from time to time in one or more classes or series and to fix the number of
shares constituting any class or series. The Prime Board has the power to fix
the terms of any such


                                       51
<PAGE>

series or class, including designations, limitations or restrictions relating
thereto, including voting rights, dividends, rights on liquidation, dissolution
or winding up, conversion or exchange rights and redemption provisions
(including sinking fund provisions), if any. The designations, rights and
preferences of any class or series of Prime Preferred which may be issued would
be set forth in a statement which would be filed with the Secretary of State of
the Commonwealth of Pennsylvania.


     The issuance in the future of shares of Prime Preferred, or the
designation of authorized but unissued shares of Prime Preferred, with voting
and other rights which may be established by the Prime Board in its discretion
without shareholder approval, may create voting impediments or otherwise delay
or prevent a change in control of Prime. By issuance of Prime Preferred, the
Prime Board could modify the rights of holders of the Prime Common. There is no
current intention to issue any Prime Preferred.


                 PROPOSAL II -- ADJOURNMENT OF SPECIAL MEETING


     In the event there are not sufficient votes to constitute a quorum for the
Special Meeting or to approve the Merger Agreement at the time of the Special
Meeting, the Merger Agreement could not be approved unless the Special Meeting
were adjourned in order to permit further solicitation of proxies. In order to
allow proxies that have been received by Prime at the time of the Special
Meeting to be voted for adjournment under these circumstances, Prime has
submitted the question of adjournment under these circumstances to its
shareholders as a separate matter for their consideration. In order to approve
any adjournment a majority of votes must be cast in favor of Proposal II.


     The Prime Board recommends that shareholders vote their proxies FOR the
Adjournment Proposal so that their proxies may be used for purposes of
adjourning the Special Meeting under the circumstances described in the
preceding paragraph.


     Properly executed proxies will be voted in favor of any such adjournment
unless otherwise indicated thereon; provided, however, that proxies voting
against the Merger Agreement will not be voted in favor of the Adjournment
Proposal unless the shareholder has voted FOR approval of the Adjournment
Proposal on the proxy card. If the Prime Board elects to adjourn the Special
Meeting, no notice of the time and place of the adjourned meeting is required
to be given to shareholders other than an announcement of such time and place
at the Special Meeting unless such adjournment exceeds 90 days.


                             SHAREHOLDER PROPOSALS


     Prime shareholders will not be entitled to submit proposals for
consideration at the Special Meeting except to the extent such proposals relate
directly to the matters to come before the Special Meeting as set forth in this
Proxy Statement-Prospectus. In the event that the Merger is not approved at the
Special Meeting and Prime subsequently holds its Annual Meeting for 1999, Prime
shareholders will be entitled to submit proposals on matters appropriate for
shareholder action consistent with regulations of the Commission and Prime's
Bylaws. No date has been set for Prime's 1999 Annual Meeting of Shareholders.


     For business to be properly brought before the 1999 Annual Meeting by a
shareholder, any shareholder proposal to take action at the meeting will be
required to be received at Prime's main office at 7111 Valley Green Road, Fort
Washington, Pennsylvania 19034-2209, not later than 30 nor more than 90 days
prior to the meeting, together with certain information concerning the
shareholder making the proposal and concerning the business proposed to be
conducted; provided, however, that if Prime gives less than 40 days' notice or
prior public disclosure of the date of the meeting to shareholders, in order to
be timely the shareholder's notice must be received no later than the 10th day
following Prime's notice or public disclosure. Any such proposals shall be
subject to the requirements of the proxy rules adopted under the Securities
Exchange Act of 1934, as amended (the "Exchange Act"). The proxy rules provide
that if the shareholder's notice is not received by Prime within a reasonable
period of time before the date Prime mails its proxy materials for the Annual
Meeting, Prime (through management proxy holders) may exercise discretionary
voting authority when the proposal is raised at the Annual Meeting without
reference to any matter in the proxy statement for the 1999 Annual Meeting.


                                       52
<PAGE>

     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 the shareholder is a
holder of record of shares entitled to vote at the meeting, (c) a description
of all agreements, arrangements or understandings between the shareholder and
any other shareholder relating to the proposal to be voted on and any financial
contractual interest of either shareholder in the outcome of such vote and (d)
all other information regarding the proposal to be voted on and the shareholder
intending to present the proposal for a vote as would be required to be
included in a proxy statement soliciting the vote of shareholders in respect of
the proposal pursuant to the proxy rules of the Commission.


                                 OTHER MATTERS


     The Prime Board is not aware of any business to come before the Special
Meeting other than those matters described above in this Proxy
Statement-Prospectus. However, if any other matters should properly come before
the Special Meeting, it is intended that proxies received will be voted in
respect thereof in accordance with the reasonable business judgment of the
person or persons voting the proxies.


                                 LEGAL MATTERS


     The legality of the Summit Common offered hereby will be passed upon for
Summit by Richard F. Ober, Jr., Esq., Executive Vice President, General Counsel
and Secretary of Summit. Mr. Ober owns 48,843 shares of Summit Common and
options to purchase 132,034 shares of Summit Common at a weighted average
exercise price of $22.11. Certain federal tax matters will be passed upon for
Summit and Prime by Thompson Coburn, St. Louis, Missouri. Certain legal matters
will be passed upon for Prime by Stradley, Ronon, Stevens & Young, LLP,
Philadelphia, Pennsylvania.

Stock held as of the Effective Time by each Prime Shareholder shall be converted
in accordance with the New Jersey Act and the Pennsylvania Law into the right to
receive  whole shares of Summit Stock and cash in lieu of  fractional  shares of
Summit Stock as follows:  the aggregate  number of shares of Prime Stock held by
each Prime  Shareholder shall be multiplied by the Exchange Ratio (as defined at
Section  1.03(c)  below) and (i) a Prime  Shareholder  shall become  entitled to
receive whole shares of Summit Stock pursuant to this Section  1.03(a)(2)  equal
in number to the whole number which results from the  foregoing  multiplication,
and (ii) a Prime  Shareholder  shall become entitled to receive cash pursuant to
this Section  1.03(a)(2) in lieu of a fractional  share of Summit Stock, if any,
equal in amount to 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  ("NYSE")  Composite
Transactions  List (as  reported in The Wall  Street  Journal or, in the absence
thereof,  as reported by another  authoritative  source  mutually agreed upon by
Prime and Summit) on the last  trading day ending  prior to the  Effective  Time
("Cash In Lieu Amount"). (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 Reorganization, both adjusted
as  and  if  necessary  in  accordance  with  Section  1.03(b),   are  sometimes
collectively referred to herein as the "Reorganization 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 ("Capital  Change"),  the Exchange Ratio and, if necessary,  the
form and  amount of Summit  capital  stock  issuable  in the  Reorganization  in
exchange for Prime Stock shall be  appropriately  adjusted to give effect to the
Capital Change.

       (c) The "Exchange Ratio" is hereby defined to be six hundred seventy-five
thousandths (.675).

       (d) Summit agrees that any Summit  Rights  issued  pursuant to the Summit
Rights  Agreement  shall be issued  with  respect to each share of Summit  Stock
issued  pursuant  to the terms  hereof  under the  terms of such  Summit  Rights
Agreement prior to the Effective  Time, as well as to take all action  necessary
or  advisable  to enable the holder of each such share of Summit Stock to obtain
the  benefit  of  such  Summit  Rights  Agreement  notwithstanding  their  prior
distribution,  including,  without  limitation,  amendment of the Summit  Rights
Agreement.

       Section  1.04.Reservation of Summit Stock; Issuance of Shares Pursuant to
the  Reorganization.  Summit shall  reserve and make  available  for issuance to
holders of Prime Stock in connection with the  Reorganization,  on the terms and

Agreement,  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
after the Effective Time to Prime Shareholders.

       Section  1.05.Exchange Agent  Arrangements.  Prior to the Effective Time,
Summit shall appoint  Equiserve First Chicago Trust Division,  or another entity

                                       3
<PAGE>

Reorganization 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 Prime Stock ("Prime  Certificates") and
Summit shall deliver to the Exchange Agent  sufficient  Summit  Certificates and
cash as shall be required to satisfy Summit's  obligations to Prime Shareholders
under Section 1.07(c), prior to the time such obligations arise.

       Section   1.06.Effective   Time.  In  the  event  that  pursuant  to  the
Reorganization  Election Summit elects the Reorganization method provided for at
Section 1.01(a)(1), the "Effective Time" of the Reorganization shall be the hour
and the date  specified in the  certificate  of merger of Summit and Prime 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") and the articles of
merger filed with the Department of State of the  Commonwealth  of  Pennsylvania
("Pennsylvania  Articles") in accordance  with Section 1927 of the  Pennsylvania
Law, which such hour and date shall be identical in both the NJ Certificate  and
the  Pennsylvania  Articles.  In the event that  pursuant to the  Reorganization
Election  Summit  elects  the  Reorganization  method  provided  for at  Section
1.01(a)(2),  the "Effective  Time" of the  Reorganization  shall be the date and
time specified in Exhibit A or determined in accordance with Exhibit A.

       Section 1.07.Exchange of Prime Certificates.

       (a) After the Effective Time and subject to Section  1.07(c) below,  each
Prime Shareholder  (except as provided  otherwise in Section  1.03(a)(1) above),
upon surrender to the Exchange Agent of all Prime Certificates registered to the
Prime  Shareholder,  shall be entitled to receive in exchange  therefor a Summit
Certificate  representing  the number of whole shares of Summit Stock such Prime
Shareholder  becomes entitled to receive pursuant to Section  1.03(a)(2) and the
Cash In Lieu  Amount,  payable  by check,  such  Prime  Shareholder  may  become
entitled  to receive  pursuant  to  Section  1.03(a)(2).  Until so  surrendered,
outstanding Prime Certificates held by each Prime Shareholder,  other than Prime
Certificates  governed by Section  1.03(a)(1),  shall be deemed for all purposes
(other than as provided below with respect to unsurrendered  Prime  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,
without  interest,  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 Prime Certificates  dividends or other  distributions,  if any, on
Summit Stock declared after the Effective Time; provided, however, that upon the
surrender  and  exchange  of Prime  Certificates  following  a dividend or other
distribution on Summit Stock there shall be paid to such Prime  Shareholders the
amount,  without interest,  of dividends and other distributions,  if any, which
became payable prior to such surrender and exchange but which were not paid.

       (b) Holders of Prime Certificates as of the Effective Time shall cease to
be, and shall have no further rights as, shareholders of Prime.

       (c) As promptly as practicable,  but in no event more than 10 days, after
the Exchange  Agent  receives an accurate  and  complete  list of all holders of
record  of   outstanding   Prime  Stock  as  of  the   Effective   Time  ("Prime
Shareholders")  (including  the  address and social  security  number of and the
number of shares of Prime  Stock  held by each  Prime  Shareholder)  from  Prime
("Final  Shareholder  List"),  Summit shall cause the Exchange  Agent to send to
each  Prime  Shareholder  instructions  and  transmittal  materials  for  use in
surrendering   and  exchanging  Prime   Certificates   for  the   Reorganization
Consideration.  Summit  shall  consult  with Prime with  respect to the form and


                                       4
<PAGE>

content of the transmittal instructions and materials and incorporate reasonable
suggestions.  If Prime 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 10 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
Prime cause the Exchange  Agent to cancel and exchange  Prime  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 Prime,
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 10-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.

       (d) At and after the  Effective  Time there shall be no  transfers on the
stock  transfer  books  of  Prime  of the  shares  of  Prime  Stock  which  were
outstanding immediately prior to the Effective Time.

       Section  1.08.Restated  Certificate of Incorporation and By-Laws.  In the
event  that  pursuant  to  the   Reorganization   Election   Summit  elects  the
Reorganization   method  provided  for  at  Section  1.01(a)(1):   the  Restated
Certificate  of  Incorporation  of  Summit in  effect  immediately  prior to the
Effective  Time  shall  be the  Restated  Certificate  of  Incorporation  of the
corporation surviving the Reorganization  ("Surviving  Corporation"),  except as
duly  amended  thereafter  and except to the extent  such is deemed by law to be
affected by the NJ Certificate;  and 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.   In  the  event  that  pursuant  to  the
Reorganization  Election Summit elects the Reorganization method provided for at
Section 1.01(a)(2),  the certificate or articles of incorporation and by-laws of
the Surviving Corporation shall be as set forth in Exhibit A.

       Section 1.09.Board of Directors and Officers.  In the event that pursuant
to the Reorganization  Election Summit elects the Reorganization method provided
for at Section 1.01(a)(1):  the Board of Directors of the Surviving  Corporation
shall  consist  of the  members  of the  Board of  Directors  of  Summit  at the
Effective Time; the officers of the Surviving  Corporation  shall consist of the
officers of Summit at the Effective  Time; and such directors and officers shall
serve  as  such  for  the  terms  prescribed  in  the  Restated  Certificate  of
Incorporation  and By-Laws of Summit,  or as otherwise  provided by law or until
their earlier deaths,  resignation or removal. In the event that pursuant to the
Reorganization  Election Summit elects the Reorganization method provided for at
Section  1.01(a)(2),  the members of the Board of Directors  and the officers of
the Surviving Corporation shall be as set forth in Exhibit A.

       Section 1.10.Prime Stock Options.

       (a) At the  Effective  Time,  each Prime  Option  (as  defined in Section
1.10(b)  below)  shall be  deemed to  constitute,  and  shall  automatically  be
converted on the terms set forth in this Section 1.10 into,  options to purchase
Summit  Stock and a  corresponding  number of Summit  Rights in the event of the
prior  distribution  contemplated by Section 1.03(d)  ("Converted  Options") and
each Converted Option (i) shall immediately vest to the extent the related Prime
Option  was  vested or as  provided  in the Prime  Stock  Compensation  Plan (as
defined at Section  2.01(d)(3)  below) under which the related  Prime Option was
granted and in the stock option  agreement by which it was  evidenced,  and (ii)
shall be administered in all material  respects in accordance with the terms and

<PAGE>

conditions  provided  for in the Prime Stock  Compensation  Plan under which the
related  Prime Option was granted and in the stock option  agreement by which it
was evidenced.  The number of shares of Summit Stock which may be purchased upon
exercise of a particular Converted Option shall be the number of shares of Prime
Stock which would have been  issuable upon exercise in full of the related Prime
Option  multiplied  by the Exchange  Ratio and rounded down to the nearest whole
number  ("Converted  Number").  The  exercise  price per  share of Summit  Stock
purchasable  upon  exercise of a  Converted  Option  shall  equal the  aggregate
exercise  price that would have been  payable  upon an  exercise  in full of the
related  Prime  Option  divided by the  Converted  Number and  rounded up to the
nearest  ten-thousandth  of a dollar.  In the event a Capital Change shall occur
prior to the Effective  Time,  an  appropriate  adjustment  shall be made to the
terms of the  Prime  Options  at the time of the  foregoing  conversion  so that
Converted  Options give effect to the Capital  Change.  Within 45 days after the
receipt  by Summit of an  accurate  and  complete  list of all  holders of Prime
Options,  all  information  about  the Prime  Options  and the  holders  thereof
(including  the  address  and social  security  number of each such holder and a
description of the Prime 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 Prime Stock subject
thereto)  and  copies of each form of option  agreement,  warrant  agreement  or
letter agreement  entered into between Prime and a holder of a Prime Option (all
of the foregoing  being  collectively  referred to as the "Final Option List and
Materials"), Summit shall issue to the holders of such Prime 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 Prime 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
Converted  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  NYSE  and for  sale by any  appropriate  state
securities regulators,  which such registrations and authorizations Summit shall
use its best efforts to effect  within 45 days after Prime shall have  delivered
to Summit the Final Option List and Materials, and Summit knows of no reason why
it will not be able to do so.  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 any Converted
Options remain outstanding.  Summit shall take all corporate action necessary to
reserve for issuance a sufficient  number of shares of Summit Stock for delivery
upon exercise of Converted Options. Notwithstanding anything in the foregoing to
the contrary,  Prime Options  intended to qualify as "incentive  stock  options"
under the Code shall be converted into Converted  Options in a manner consistent
with the preservation of such qualification under the Code.

       (b) For purposes of this Section 1.10,  "Prime  Option" is hereby defined
to mean an option  relating  to the  purchase  of Prime  Stock,  and any  rights
appurtenant  thereto  including  Equity  Based  Rights  (as  defined  at Section
2.01(d)(2) below),  granted under a Prime Stock Compensation Plan (as defined at
Section  2.01(d)(3)  below),  outstanding  both on the  date  hereof  and at 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  Prime  acquired  or to be  acquired  by the
Surviving  Corporation as a result of, or in connection with, the Reorganization
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


                                       6
<PAGE>

and on behalf of Prime or otherwise,  all such deeds, bills of sale, assignments
and assurances  and to take, in the name and on behalf of Prime,  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  Reorganization   Consideration.   If,  upon  the
expiration   of  one  year   following  the   Effective   Time,   Reorganization
Consideration  remains  with the  Exchange  Agent  due to the  failure  of Prime
Shareholders  to surrender and exchange Prime  Certificates  for  Reorganization
Consideration,  Summit may,  at its  election,  continue to retain the  Exchange
Agent for purposes of the surrender and exchange of Prime  Certificates  or take
possession of such unclaimed Reorganization Consideration,  in which such latter
case, Prime  Shareholders who have theretofore  failed to surrender and exchange
Prime  Certificates  shall  thereafter  look only to Summit  for  payment of the
Reorganization  Consideration  and the unpaid  dividends  and  distributions  on
Summit Stock declared after the Effective  Time,  without any interest  thereon.
Notwithstanding the foregoing,  none of Summit, Prime, the Exchange Agent or any
other person  shall be liable to any former  holder of shares of Prime Stock for
any property  properly  delivered to a public  official  pursuant to  applicable
abandoned property, escheat or similar laws.

       Section 1.13.Lost Prime Certificates.  In the event any Prime Certificate
shall have been lost,  stolen or  destroyed,  upon the making of an affidavit of
that fact by the person  claiming such Prime  Certificate to be lost,  stolen or
destroyed and the posting by such person of a personal,  nonsurety  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 Prime  Certificate,  the
Exchange Agent will issue in exchange for such lost,  stolen or destroyed  Prime
Certificate  the  Reorganization  Consideration  deliverable in respect  thereof
pursuant to this Agreement.


                                   ARTICLE II.
                     REPRESENTATIONS AND WARRANTIES OF PRIME

       Prime  represents  and  warrants  to  Summit  as  follows  (where an item
required to be disclosed on a Prime  Schedule is required to be disclosed on one
or more additional  Prime  Schedules,  or where a copy of an item required to be
attached  to a  Prime  Schedule  is  required  to be  attached  to one  or  more
additional Prime Schedules, such disclosure or copy need not be provided on more
than one Prime Schedule  provided the Prime  Schedules with respect to which the
disclosure or copy is required but not provided contain a cross reference to the
location of the  required  disclosure  or copy in the Prime  Schedules  which is
clear and unambiguous):

       Section 2.01.Organization, Capital Stock.

       (a) Each of Prime and its  nonbank  subsidiaries,  including  the nonbank
subsidiaries of Bank (as defined in Section 2.01(e) (the term  "subsidiary",  as
used in this  Agreement,  shall mean any  corporation or other  organization  of
which  10% or 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  similar  functions with respect to such  corporation or other
organization  is  directly or  indirectly  owned by Prime or a  "subsidiary"  of
Prime; the term "indirect" ownership means ownership through a succession of one
or more  other  subsidiaries),  all of which are  listed,  together  with  their
respective states of incorporation and direct and indirect beneficial owners, on
Prime Schedule 2.01(a), is a corporation duly organized,  validly subsisting and


                                       7
<PAGE>

in good standing under the laws of the state of its incorporation,  qualified to
transact  business  under the laws of all  jurisdictions  where it does business
except where the failure to be so qualified  could not reasonably be expected to
have a material  adverse  effect on (i) the  business,  results  of  operations,
assets or financial  condition of Prime and its  subsidiaries  on a consolidated
basis,  or (ii) the ability of Prime to perform its  obligations  under,  and to
consummate the  transactions  contemplated  by, this Agreement  ("Prime Material
Adverse  Effect").  However,  a Prime Material  Adverse Effect or Prime Material
Adverse  Change (as  defined at Section  2.03  below)  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
Reorganization.  Each of Prime 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, and each has complied in all
material respects with all applicable laws, regulations and orders.

       (b) Prime is registered as a bank holding  company under the Bank Holding
Company Act of 1956, as amended ("BHCA").

       (c) Prime or one of its  subsidiaries is the holder and beneficial  owner
of all of the  outstanding  capital stock of all of Prime's  direct and indirect
nonbank subsidiaries.

       (d) (1) The  authorized  capital  stock of Prime  consists of  13,000,000
shares of Common Stock,  par value $1.00 per share, of which  10,984,833  shares
are  issued and  outstanding  as of the date  hereof,  and  2,000,000  shares of
Preferred  Stock,  par value  $1.00 per share,  of which no shares are issued or
outstanding. All issued and outstanding shares of the capital stock of Prime and
of each of its nonbank  subsidiaries  have been fully paid, were duly authorized
and  validly  issued,  are  nonassessable  and have been  issued  pursuant to an
effective  registration  statement  under the Securities Act of 1933, as amended
(the  "Securities  Act")  or to the best of  Prime's  knowledge  an  appropriate
exemption  from  registration  under the  Securities  Act and were not issued in
violation of the preemptive rights of any shareholder.

              (2)  Except  as  set  forth  in  Section  2.01(d)(1),  all  Equity
Securities  (as  defined at Section  2.01(d)(4)  below) of Prime and its nonbank
subsidiaries outstanding,  in existence, the subject of an agreement or reserved
for  issuance  ("Current  Equity  Securities"),  and all rights or  entitlements
appurtenant  to, based upon,  derived from or valued based on the performance or
value of Equity Securities of Prime outstanding, in existence, the subject of an
agreement or reserved for issuance  ("Equity  Based Rights") are listed on Prime
Schedule  2.01(d)(2) and all  significant  information  relating to such Current
Equity Securities (other than Common Stock) and Equity Based Rights is listed on
Prime Schedule 2.01(d)(2) including without limitation,  where applicable,  name
of holder,  address and  relationship  to Prime if not an employee of Prime or a
subsidiary,  date of grant, award or issuance,  expiration dates, vesting dates,
the Prime  Stock Plan (as  defined  in Section  2.01(d)(3)  below)  under  which
granted,  awarded or issued, any intended  qualification or  nonqualification or
other status under the Code,  those  Current  Equity  Securities or Equity Based
Rights  granted in tandem with other Current  Equity  Securities or Equity Based
Rights,  exercise  price,  number of shares,  valuation  formula and performance
goals.  All Current Equity  Securities  have been (to the extent such is capital
stock or similar equity  interest)  fully paid, were duly authorized and validly
issued,  are (to the extent such is capital  stock or similar  equity  interest)
nonassessable  and  have  been  issued  pursuant  to an  effective  registration
statement  under  the  Securities  Act or to the best of  Prime's  knowledge  an
appropriate  exemption from  registration  under the Securities Act and were not
issued in violation of the preemptive rights of any shareholder.

                                       8
<PAGE>

              (3) All agreements,  contracts,  plans and  arrangements,  whether
oral or  written  or  formal  or  informal,  pursuant  to which  Current  Equity
Securities  or Equity  Based  Rights  were  granted,  awarded or issued or which
provide for the  granting,  awarding or issuance of Equity  Securities or Equity
Based  Rights or are  relevant in any fashion to Current  Equity  Securities  or
Equity  Based  Rights   ("Prime  Stock  Plan")  are  listed  in  Prime  Schedule
2.01(d)(3).  All Prime Stock Plans constituting a compensatory contract, plan or
arrangement ("Prime Stock Compensation Plan"), including all amendments thereto,
are separately  identified on Prime Schedule  2.01(d)(3) and except as disclosed
thereon have been duly approved by the  shareholders of Prime and such approvals
have  been  obtained  in  compliance  with  all  applicable  laws  and  with all
applicable regulations of governmental or self-regulatory authorities.

              (4) "Equity  Securities"  of an issuer means (i) the capital stock
or other equity  securities  or equity  interests of such issuer,  (ii) options,
warrants, scrip, interests in, rights (including preemptive rights) to subscribe
to,  purchase or acquire,  calls on or commitments  of any character  whatsoever
relating to, or  securities  or rights  convertible  into or  exchangeable  for,
capital stock or other equity  securities or equity interests or any security or
right  convertible  into or  exchangeable  for the capital stock or other equity
security or equity interests of such issuer,  and (iii) contracts,  commitments,
obligations,  agreements,  understandings  or arrangements  entitling  anyone to
acquire  from the  issuer,  or by which such  issuer is or may  become  bound to
issue, capital stock or other equity security or equity interest or any security
or right  convertible into or exchangeable for the capital stock or other equity
security or equity interest of such issuer.

       (e) Prime owns no bank  subsidiary  other  than the Prime 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  subsisting,  and in good standing under the
laws of 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 a Prime Material Adverse Effect.  Bank is duly
authorized  to conduct all  activities  and  exercise all powers of a commercial
bank  contemplated by the laws of its jurisdiction of  organization.  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 Prime Schedule  2.01(f).  Prime 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 Prime Schedule 2.01(f).

       (g)  All  Equity  Securities  of its  direct  and  indirect  subsidiaries
beneficially  owned by Prime or a subsidiary of Prime are held free and clear of
any claims, liens, encumbrances or security interests.

       Section 2.02.Financial  Statements. The financial statements (and related
notes and schedules  thereto)  contained in or  incorporated  by reference  into


                                       9
<PAGE>

Prime's (a) annual report to shareholders for the fiscal year ended December 31,
1997, (b) annual report on Form 10-K filed  pursuant to the Securities  Exchange
Act of 1934, as amended  ("Exchange Act") for the fiscal year ended December 31,
1997 and (c) quarterly  reports on Form 10-Q filed  pursuant to the Exchange Act
for the fiscal  quarters  ended March 31, 1998,  June 30, 1998 and September 30,
1998 and the financial  statements  (and related  notes and  schedules  thereto)
contained in Prime's  draft annual  report to  shareholders  for the fiscal year
ended  December  31, 1998  attached  hereto as Prime  Schedule  2.02 (all of the
foregoing  financial  statements  being  collectively  referred to as the "Prime
Financial Statements") are true and correct in all material respects as of their
respective dates and each fairly presents in all material respects (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 Prime and its  subsidiaries  at its respective date and
for the period to which it relates, except as may otherwise be described therein
and except that, in the case of unaudited statements, no consolidated statements
of changes in stockholders' equity are included.  The Prime 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 Prime  Financial  Statements,  in light of the  circumstances
under which they were made, misleading in any respect.

       Section  2.03.No  Conflicts.  Except as set forth on Prime Schedule 2.03,
Prime and each of its  subsidiaries  is not in violation or breach of or default
under, and has received no notice of violation, breach, revocation or threatened
or contemplated  revocation of or default or denial of approval under,  nor will
the  execution,  delivery and  performance  of this  Agreement by Prime,  or the
consummation   of   the   transactions   contemplated   hereby   including   the
Reorganization  by Prime 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 Prime or any
of its subsidiaries or upon any of the Equity  Securities of Prime or any of its
subsidiaries, or constitute an event which could, with the lapse of time, action
or inaction by Prime 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:

       (i)    the  certificate  or  articles  of  incorporation  or  articles of
              association,  as  appropriate,  or  by-laws of Prime or any of its
              subsidiaries;

       (ii)   any  applicable  law,  statute,   rule,   ruling,   determination,
              ordinance or regulation of or agreement with any  governmental  or
              regulatory authority;

       (iii)  any  judgment,  order,  writ,  award,  injunction or decree of any
              court or other governmental authority; or

       (iv)   any material note, bond,  mortgage,  indenture,  lease,  policy of
              insurance  or  indemnity,  license,  contract,  agreement or other
              instrument;

to which Prime or any of its subsidiaries is a party or by which Prime 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 result in a
material  adverse  change in the  business,  results  of  operations,  assets or
financial condition of Prime and its subsidiaries, on a consolidated basis, from
that  reflected in the Prime  Financial  Statements as of and for the year ended


                                       10
<PAGE>

December 31, 1998 ("Prime  Material  Adverse  Change"),  or enable any person to
enjoin the transactions contemplated hereby.

       Section 2.04.Absence of Undisclosed  Liabilities.  Except as set forth on
Schedule  2.04,  Prime  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 Prime 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 Prime  Financial  Statements  or
disclosed  in the notes  thereto,  (b)  commitments  made by Prime or any of its
subsidiaries in the ordinary course of its business, and (c) liabilities arising
in the ordinary course of its business since December 31, 1998, which are not in
the aggregate material to Prime and its subsidiaries,  on a consolidated  basis.
Other than as may be set forth on Prime Schedule 2.04,  neither Prime nor any of
its subsidiaries  has, since December 31, 1998, become obligated on any debt due
in more than one year  from the date of this  Agreement  in excess of  $100,000,
other than intra-corporate debt and deposits received, repurchase agreements and
borrowings  from the Federal  Home Loan Bank of  Pittsburgh  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 Prime or any of its  subsidiaries
which  materially  and  adversely  affects  Prime  and  its  subsidiaries,  on a
consolidated  basis, and there are no actions,  arbitrations,  claims,  charges,
suits,  investigations or proceedings (formal or informal) material to Prime and
its subsidiaries,  on a consolidated  basis,  pending or, to the best of Prime's
knowledge,  threatened, against or involving Prime 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 Prime  referred  to in  Section  2.02 or set forth in
Prime Schedule 2.05.  Except as set forth on Prime Schedule 2.05,  neither Prime
nor any  subsidiary  of Prime  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.  Except as set forth
on Prime  Schedule  2.05,  neither  Prime nor any  subsidiary  of Prime 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 Prime nor any subsidiary of Prime 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 Prime's or a Prime  subsidiary's  business nor has
Prime or any subsidiary of Prime been advised of any significant deficiencies by
any such agency in connection with any current  examination of either Prime or a
subsidiary of Prime by any such agency.

       Section  2.06.Brokers'  Fees.  Prime 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 Fox-Pitt,
Kelton Inc.  ("Fox-Pitt").  Prime  Schedule  2.06  consists of true and complete
copies  of all  agreements  between  Prime  and  Fox-Pitt  with  respect  to the
transactions contemplated by this Agreement or similar transactions.

       Section  2.07.Regulatory  Filings.  All  filings  made by  Prime  and its
subsidiaries  after  December  31,  1995 with the SEC and the  appropriate  bank
regulatory  authorities  did  not at the  time  of  filing  contain  any  untrue
statement  of a  material  fact  and 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 or the Federal bank  regulatory  agency having  securities
regulatory  jurisdiction,  as  appropriate.  Each  of the  financial  statements
(including  related notes and schedules thereto) contained in or incorporated by
reference into such filings 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 Prime and its  subsidiaries  at its respective date or for the
period to which it relates,  except as may  otherwise be  described  therein and
except that, in the case of unaudited statements,  no consolidated statements of
changes  in  stockholders'  equity  are  included.  Except as set forth on Prime
Schedule 2.07, Prime and its  subsidiaries  have since December 31, 1995, to the
extent legally required,  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 Prime of
this  Agreement,  the  Reorganization  and the other  transactions  contemplated
hereby in accordance with Prime's Articles of Incorporation and the Pennsylvania
Law at a meeting  of such  holders  to be duly  called  and held,  Prime 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 Prime has
taken all action required by law, its Articles of Incorporation,  its By-Laws or
otherwise (i) to authorize the execution and delivery of this Agreement and (ii)
for  shareholders  of Prime  to  approve  this  Agreement  and the  transactions
contemplated  hereby  including the  Reorganization  by a simple majority of the
shares  entitled to vote at the meeting held in  accordance  with Section  4.03.
Assuming due execution and delivery by and the enforceability  against Summit of
this  Agreement,  this  Agreement  is a valid  and  binding  agreement  of Prime
enforceable  in  accordance  with its terms  except as such  enforcement  may be
limited by  applicable  principles  of equity,  and by  bankruptcy,  insolvency,
reorganization,  fraudulent  transfer,  moratorium  or  other  laws  of  general
applicability  presently or hereafter in effect  affecting  the  enforcement  of
creditors' rights generally or institutions the deposits of which are insured by
the  Federal  Deposit   Insurance   Corporation,   or  the  affiliates  of  such
institutions.  The Board of Directors of Prime in  authorizing  the execution of
this  Agreement  has  determined to recommend to the  shareholders  of Prime the
approval  of this  Agreement,  the  Reorganization  and the  other  transactions
contemplated hereby.

       Section  2.09.Absence of Changes.  There has not been, since December 31,
1998,  any Prime  Material  Adverse  Change  except as may be set forth in Prime
Schedule 2.09. Except as may be set forth in Prime Schedule 2.09,  neither Prime
nor any of its subsidiaries  has since December 31, 1998: (a) (i) declared,  set
aside or paid any  dividend  or other  distribution  in  respect  of its  Equity
Securities,   other  than  dividends  from   subsidiaries   to  Prime  or  other
subsidiaries  of Prime,  and an ordinary cash dividend to Prime  shareholders of
$0.11 per share or less per fiscal  quarter,  or, (ii)  directly  or  indirectly
purchased,  redeemed or otherwise  acquired any shares of any Equity Securities;
(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) 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 $75,000, whether or not covered by insurance,  adversely affecting its
business,  property  or  assets,  or  waived  any  rights  of value in excess of
$75,000;  (f) entered into  transactions  other than in the  ordinary  course of
business which in the aggregate  exceeded  $150,000;  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 Credit  Losses.  At  December  31,  1998 and
thereafter the allowances for credit losses of Prime 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 Prime's  knowledge,  the loan and lease
portfolios of Prime in excess of such allowances are collectible in the ordinary
course of business.  Prime  Schedule  2.10  constitutes  a list of all loans and
leases made by Prime 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.  Subject to the exceptions set forth
on Prime Schedule 2.11:

Neither  Prime  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 Prime or any
of its  subsidiaries.  None of the  property  being  acquired  by  Summit or its
subsidiaries in the  Reorganization 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
Prime 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. All federal,  state and local returns
(as defined below) required to be filed have been timely filed by Prime 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),  are accurate,  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 Prime or any of its subsidiaries, have been paid in full or adequate
provision  therefor has been  included on the books of Prime or its  appropriate
subsidiary.  Neither Prime nor any of its  subsidiaries  is required to file tax
returns with any state other than the  Commonwealth of  Pennsylvania.  Provision
has been made on the books of Prime or its appropriate subsidiary for all unpaid
taxes, whether or not disputed,  that may become due and payable by Prime or any
of its  subsidiaries  in future  periods in respect  of  transactions,  sales or
services  occurring  or  performed  prior  to the  date of this  Agreement.  The
Internal  Revenue  Service  ("IRS") has never audited the  consolidated  federal
income  tax  returns of Prime and the  Commonwealth  of  Pennsylvania  has never
audited  the  Pennsylvania  income tax  returns  of Prime and its  subsidiaries.


                                       13
<PAGE>

Neither  Prime nor any of its  subsidiaries  is subject to an audit or review of
its tax returns by any state other than the  Commonwealth of Pennsylvania or the
State of  Delaware.  Neither  Prime 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 the best of Prime's  knowledge,  threatened against
Prime  or any of its  subsidiaries,  including  a  claim  or  assessment  by any
authority in a jurisdiction  where Prime or any of its  subsidiaries do not file
tax returns and Prime 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 Prime 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 Prime or any of its  subsidiaries,  and neither
Prime nor any of its  subsidiaries  has any knowledge  that the IRS has proposed
any such adjustment or change in accounting  method.  Prime 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 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.

       For purposes of this  Agreement,  "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; and "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.  Except  as set forth in Prime  Schedule  2.12,
Prime 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 Prime Financial  Statements (except  individual  properties and
assets  disposed of since December 31, 1998 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 Prime Financial  Statements
or which in the  aggregate  do not  materially  adversely  affect or impair  the
operation of Prime and its subsidiaries on a consolidated  basis. Prime and each
of its  subsidiaries  enjoys  peaceful  and  undisturbed  possession  under  all
material  leases  under which it is the lessee,  where the failure to enjoy such
peaceful and  undisturbed  possession  would be likely to have a Prime  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 Prime and its subsidiaries, on a consolidated basis.

       Section  2.13.Condition of Properties;  Insurance.  All real and tangible
personal properties owned or leased by Prime or any of its subsidiaries are in a
good state of maintenance and repair, are in good operating  condition,  subject
to normal wear and tear,  conform (as to owned  properties only) in all material
respects to all  applicable  ordinances,  regulations  and zoning laws,  and are
adequate  for the  business  conducted  by Prime or such  subsidiary  subject to
exceptions  which  are  not,  in  the  aggregate,  material  to  Prime  and  its
subsidiaries,  on a  consolidated  basis.  Prime  and  each of its  subsidiaries
maintains insurance (with companies which, to the best of Prime's knowledge, are
approved by all appropriate  state  insurance  regulators to sell such insurance
where  purchased by Prime)  against loss relating to such  properties and to the
best of Prime's  knowledge  such  other  risks as  companies  engaged in similar


                                       14

business  located in  Pennsylvania,  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 Prime and each of its  subsidiaries  from any
adverse loss resulting from risks and liabilities  reasonably foreseeable at the
date hereof,  and are  disclosed on Prime  Schedule  2.13.  All material  claims
thereunder have been filed in a due and timely fashion. Since December 31, 1994,
neither Prime 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 has Prime or any  subsidiary  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, other than premium increases in the ordinary course
of business applicable on their terms to all insureds.

       Section 2.14.Contracts.

       (a) Except as set forth in Prime Schedule 2.14(a),  neither Prime 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 $75,000.

       (b) Except as set forth in, and, in Prime Schedule 2.03 or Prime Schedule
2.14(b),  neither  Prime 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 Prime bargaining contract
or union agreement) or other agreement with any director or any officer or other
employee of Prime or any subsidiary,  the benefits of which are  contingent,  or
the terms of which are materially altered,  upon the occurrence of a transaction
involving Prime or any of its  subsidiaries  of the nature  contemplated by this
Agreement which is not terminable  without penalty by Prime or a subsidiary,  as
appropriate,  on 60 days or less notice; (ii) contract or commitment for capital
expenditures  in excess of $75,000  for any one project or in excess of $150,000
in the aggregate for all projects;  (iii) contract or commitment whether for the
purchase of materials or supplies or for the  performance of services  involving
consideration  in  excess  of  $75,000  (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 to sell  OREO
property,  involving  consideration in excess of $75,000; (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 Prime
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  Prime  (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 Prime or any of its subsidiaries,  (viii) contract (other than this
Agreement)  limiting the freedom of Prime 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) any other contract


                                       15

material to the business of Prime and its subsidiaries, on a consolidated basis,
and not made in the ordinary course of business.

       (c) Neither Prime 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  Prime,  is
materially  adverse,  onerous, or harmful to any aspect of the business of Prime
and its subsidiaries, on a consolidated basis.

       Section 2.15.Pension and Benefit Plans.

       (a)  Neither  Prime 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  maintained  after
December  31,  1995,  except  employee  pension  benefit  plans  listed in Prime
Schedule  2.15(a)  (individually  a "Prime  Pension Plan" and  collectively  the
"Prime Pension Plans").  In its present form each Prime Pension Plan complies in
all material respects with all applicable requirements under ERISA and the Code.
Each Prime Pension Plan and the trust created thereunder which is intended to be
qualified  and  exempt  under  Sections  401(a)  and  501(a)  of the  Code is so
qualified and exempt, and Prime or the subsidiary whose employees are covered by
such Prime 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  Prime  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 Prime or any subsidiary  whose  employees are covered by a Prime 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  Prime  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 Prime  Pension  Plan or has been misled as to his or her rights under
such Prime  Pension Plan. No Prime Pension Plan is subject to Section 412 of the
Code or Title IV of ERISA.  Except as set forth on Prime  Schedule  2.15(c),  no
person has engaged in any  prohibited  transaction  involving  any Prime 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 Prime  Pension Plans or any fiduciary  thereof
which would subject Prime 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, 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  Prime is a member  and  which is under
common control within the meaning of Section 414 of the Code.  Neither Prime 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. Except as set forth in Prime Schedule 2.15(a),  there are no
unfunded benefit or pension plans or arrangements,  or any individual agreements
whether  qualified  or not, to which Prime 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 Prime Pension Plan which is


                                       16
<PAGE>

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 Prime Pension Plan
allocable to such vested or accrued benefits. No Prime Pension Plan or any trust
created  thereunder  has been  terminated,  nor has there  been any  "reportable
events"  with  respect  to any Prime  Pension  Plan,  as that term is defined in
Section  4043 of ERISA since  December 31,  1992.  No Prime  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 Prime
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 Prime Pension Plan.

       (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 Prime Stock  Compensation  Plans and medical,
major medical,  disability,  life  insurance or dental plans covering  employees
generally, other than the Prime Pension Plans, maintained by Prime or any of its
subsidiaries  with an  annual  cost in excess of  $75,000  (collectively  "Prime
Benefit  Plans") are listed in Prime Schedule  2.15(b) (unless already listed in
Prime Schedule 2.15(a) or Prime Schedule  2.01(d)(3)) 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 Prime Benefit Plans have been  administered and communicated to
the participants and  beneficiaries in all material  respects in accordance with
their terms and ERISA,  as applicable,  and no employee or agent of Prime 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 a Prime 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 Prime Benefit
Plans or has been misled as to their rights under the Prime Benefit Plans. There
are no pending or  threatened  claims  (other than routine  claims for benefits)
against  the  Prime  Benefit  Plans  which  would  subject  Prime  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 Prime 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 the best of Prime's knowledge,  threatened
litigation,  administrative  action or proceeding  relating to any Prime Benefit
Plan or Prime  Pension  Plan.  There has been no  announcement  or commitment by
Prime or any  subsidiary of Prime to create an additional  Prime Benefit Plan or
Prime  Pension  Plan,  or to amend a Prime  Benefit Plan or Prime  Pension Plan,
except for amendments  required by applicable law, which may materially increase
the cost of such Prime  Benefit Plan or Prime  Pension Plan and,  except for any
plans or amendments  expressly  described on Prime  Schedule  2.01(d)(3),  Prime
Schedule  2.15(a) or Prime Schedule  2.15(b),  Prime and its subsidiaries do not
have any obligations for  post-retirement or post-employment  benefits under any
Prime  Benefit  Plan  (exclusive  of any coverage  mandated by the  Consolidated
Omnibus  Budget  Reconciliation  Act of 1985 ("COBRA") that cannot be amended or
terminated  upon more  than  sixty  (60)  days'  notice  without  incurring  any
liability  thereunder.  Disclosed on Prime Schedule 2.15(c) with respect to each
Prime Benefit Plan and Prime Pension Plan, to the extent applicable,  is (A) the
most recent annual report on the  applicable  form of the Form 5500 series filed


                                       17
<PAGE>

with the IRS with all the  attachments  filed,  (B) such Prime  Benefit  Plan or
Prime Pension Plan,  including all 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.

       Section  2.16.Fidelity  Bonds. Since December 31, 1995, Prime 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 timely  fashion.  Since  December  31,  1992,  there has been no
individual claim under such bonds in excess of $1 million and since December 31,
1995 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  $100,000),  neither  Prime 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, the cost of which has not been reserved or expensed in
the Prime Financial  Statements,  and aggregate deductible amounts both incurred
and reserved or expensed  since  December 31, 1995 have not exceeded $1 million.
Neither  Prime  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 Prime's and its subsidiaries' past claim experience.

       Section 2.17.Labor Matters. Hours worked by and payment made to employees
of Prime 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 Prime 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 Prime or its  appropriate  subsidiary.  Prime 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 Prime 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  Prime  or  any  of  its
subsidiaries.  Since  December  31,  1994,  no  employee  of Prime 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 Prime or
any  of its  subsidiaries  are  unionized  nor  has  union  representation  been
requested  by any group of  employees  or any other  person  within the last two
years. There are no organizing  activities  involving Prime pending with, or, to
the  knowledge  of Prime,  threatened  by,  any labor  organization  or group of
employees of Prime.

       Section 2.18.Books and Records. The minute books of Prime and each of its
subsidiaries  contain  complete and accurate  records of and fairly  reflect all
actions taken at all meetings of the shareholders and of the boards of directors
and committees  thereof and accurately reflect all other corporate action of the
shareholders and the boards of directors and each committee  thereof.  The books
and records of Prime and each of its subsidiaries  fairly and accurately reflect
the  transactions  to which Prime and each of its  subsidiaries is or has been a
party or by which  their  properties  are  subject or bound,  and such books and
records have been properly kept and maintained.

                                       18
<PAGE>

       Section  2.19.Concentrations  of Credit.  No customer or affiliated group
(as defined by applicable banking laws and regulations) of customers (a) is owed
by Prime or any  subsidiary of Prime an aggregate  amount equal to more than 10%
of the  shareholders'  equity of Prime or such subsidiary  (including  deposits,
other  debts  and  contingent  liabilities)  or (b)  owes to Prime or any of its
subsidiaries  an aggregate  amount  equal to more than 10% of the  shareholders'
equity of Prime or such subsidiary (including loans and other debts,  guarantees
of debts of third parties,  and other contingent  liabilities) other than as set
forth in Prime Schedule 2.19.

       Section  2.20.Trademarks  and  Copyrights.  Neither  Prime nor any of its
subsidiaries  has received  written notice that the manner in which Prime or any
of its  subsidiaries  conducts  its  business  including  its current use of any
material  trademark,  trade name,  service mark or copyright  violates  asserted
rights of others in any trademark,  trade name, service mark, copyright or other
proprietary right.

       Section 2.21.Equity Interests.  Neither Prime nor any of its subsidiaries
owns,  directly or indirectly,  except for the equity interests of Prime in Bank
and the equity interests  disclosed on Prime Schedule 2.01(a) and Prime Schedule
2.21, any equity interest,  other than by virtue of a security interest securing
an obligation not presently in default, in any bank, corporation, partnership or
other entity,  except: (a) in a fiduciary capacity; or (b) an interest valued at
less than $35,000  acquired in connection  with a foreclosure or debt previously
contracted.  None of the investments reflected in the consolidated balance sheet
of Prime as of December 31, 1998, and none of such investments made by it or any
of its  subsidiaries  since  December  31, 1998,  is subject to any  restriction
(contractual or statutory),  other than applicable  securities  laws, that would
materially  impair the ability of the entity holding such  investment  freely to
dispose  of  such  investment  at any  time,  except  to  the  extent  any  such

                    REPRESENTATIONS AND WARRANTIES OF SUMMIT

       Summit represents and warrants to Prime as follows:

       Section 3.01.Organization, Capital Stock.

       (a) Summit is a corporation duly organized,  validly existing and in good
standing under the laws of the State of New Jersey with authorized capital stock
consisting of (i) 390,000,000  shares of Common Stock, par value $.80 per share,
with the Summit Rights attached  thereto  pursuant to the Rights  Agreement,  of
which 173,756,531 shares were issued and outstanding as of December 31, 1998 and
(ii) 6,000,000  shares of Preferred  Stock,  each without par value, of which no
shares are issued and  outstanding  and  1,500,000  shares of Series R Preferred
Stock are reserved for issuance as of the date hereof

       (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 could
reasonably  be expected to 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").  However,  a Summit  Material
Adverse  Effect or Summit  Material  Adverse Change (as defined at Section 3.03)
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  Reorganization.  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 and each has complied with all applicable laws, regulations
and orders  except  where the failure to comply  would not  constitute  a Summit
Material  Adverse  Effect.  Summit is duly  registered as a bank holding company
under the 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 to the best of  Summit's  knowledge  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) 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 Series R Preferred  Stock issuable  pursuant
to the Summit Rights Agreement.

       (d)  All  Equity  Securities  of its  direct  and  indirect  subsidiaries


                                       23
<PAGE>

beneficially  owned by Summit or a subsidiary  of Summit are held free and clear
of any claims, liens, encumbrances or security interests.

       (e) Each bank  subsidiary  of Summit is duly  authorized  to conduct  all
activities  and  exercise  all  powers  of a  commercial  bank or  savings  bank
contemplated  by the laws of its  jurisdiction of  organization.  Each such bank
subsidiary is an insured bank as defined in the Federal Deposit Insurance Act.

       Section 3.02.Financial  Statements. The financial statements (and related
notes and schedules  thereto)  contained in or  incorporated  by reference  into
Summit's (a) annual report to  shareholders  for the fiscal year ended  December
31, 1997,  (b) annual  report on Form 10-K  pursuant to the Exchange Act for the
fiscal year ended December 31, 1997 and (c) quarterly reports on Form 10-Q filed
pursuant to the Exchange Act for the fiscal  quarters ended March 31, 1998, June
30, 1998 and September 30, 1998 (the "Summit Financial Statements") are true and
correct in all material  respects as of their  respective  dates and each fairly
presents in all material respects (subject, in the case of unaudited statements,
to recurring audit adjustments normal in nature and amount),  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
or for the period to which it  relates,  except as may  otherwise  be  described
therein and except that, in the case of unaudited  statements,  no  consolidated
statements of changes in stockholders' equity are included. 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  violation or breach of or
default under,  and has received no notice of violation,  breach,  revocation or
threatened or contemplated revocation of or default or denial of approval under,
nor will the execution, delivery and performance of this Agreement by Summit, or
the consummation of the  Reorganization  by Summit upon the terms and conditions
provided herein (assuming receipt of the Required Consents),  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
rights,  permits,  licenses,  assets or  properties  material  to Summit and its
subsidiaries,  on a  consolidated  basis,  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:

       (i)    the  Restated  Certificate  of  Incorporation  or the  By-Laws  of
              Summit;

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

       (iii)  any judgment,  order,  writ, award,  injunction,  or decree of any
              court or other governmental authority; or

       (iv)   any material note, bond,  mortgage,  indenture,  lease,  policy of
              insurance or indemnity,  license,  contract,  agreement,  or other
              instrument;

                                       24
<PAGE>
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 material  adverse
change in the business, results of operations,  assets or financial condition of
Summit and its subsidiaries, on a consolidated basis, from that reflected in the
Summit  Financial  Statements as of and for the nine months ended  September 30,
1998 (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  is  no  outstanding  order,  injunction,   or  decree  of  any  court  or
governmental  or  self-regulatory  body  against  or  affecting  Summit  or  its
subsidiaries which materially and adversely affects Summit and its subsidiaries,
on a  consolidated  basis,  and  there  are no  actions,  arbitrations,  claims,
charges,  suits,  investigations or proceedings (formal or informal) material to
Summit and its subsidiaries,  on a consolidated  basis,  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.  Neither  Summit  nor any  bank
subsidiary of Summit 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 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
[as to which Summit has not been advised of any significant deficiencies].

       Section 3.05.Regulatory  Filings. At the time of filing, all filings made
by  Summit  and its  subsidiaries  after  December  31,  1995  with  the SEC and
appropriate bank regulatory  authorities did not contain any untrue statement of
a  material  fact and did not omit to state any  material  fact  required  to be
stated herein or therein or necessary to make the statements contained herein or
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.  Summit has since  December  31,  1995  timely  made all
filings required by the Securities Act and the Exchange Act, as appropriate, and
all applicable  rules and regulations  thereunder of the SEC or the Federal bank
regulatory agency having  securities  regulatory  jurisdiction,  as appropriate.
Each of the financial statements (including related notes and schedules thereto)
contained in or incorporated by reference into such filings 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  Summit  and its  subsidiaries  at its
respective date and for the period to which it relates,  except as may otherwise
be  described  therein and except that in the case of unaudited  statements,  no
consolidated statements of changes in stockholders equity is included.

       Section 3.06.Corporate Action.

laws of general  applicability  presently or hereafter in effect  affecting  the
enforcement of creditors' rights generally or institutions the deposits of which
are insured by the Federal Deposit Insurance  Corporation,  or the affiliates of
such institutions.

Summit  which  may  result in any such  Summit  Material  Adverse  Change in the
future.

       Section  3.08   Absence  of   Undisclosed   Liabilities.   There  are  no

notes thereto,  (b) commitments made by Summit or any of its subsidiaries in the
ordinary  course of its  business  which are not in the  aggregate  material  to
Summit  and its  subsidiaries,  on a  consolidated  basis,  and (c)  liabilities
arising in the ordinary  course of its business  since  September 30, 1998 which
are  not  in the  aggregate  material  to  Summit  and  its  subsidiaries,  on a
consolidated basis.

       Section  3.09.Allowance  for Credit  Losses.  At  September  30, 1998 and
thereafter,  the allowances for credit losses of Summit and its subsidiaries are
adequate in all material  respects to provide for all losses on loans and leases

knowledge of any fact or  circumstance  that would (i) prevent the  transactions
contemplated  hereby from qualifying as a  reorganization  within the meaning of

subsidiaries are in substantial compliance with the applicable provisions of the
Community Reinvestment Act of 1977 and the regulations  promulgated  thereunder,

examination.  As of the date of this Agreement, Summit and its subsidiaries have

circumstances  which, if true, would cause Summit or any bank subsidiary to fail
to be in substantial compliance with such provisions.

       Section  3.12.Year 2000 Compliant.  To the best knowledge of Summit,  all
computer  software  and  hardware  owned or  licensed  by  Summit  or any of its

outside the range 1900-1999 will be correctly processed in any level of computer
hardware  or  software  including,  but not  limited  to,  microcode,  firmware,
applications  programs,  files and databases,  except where the failure to be so
compliant would not have a Summit Material Adverse Effect. All computer software
owned or  licensed  by Summit is, or Summit has taken  steps or is taking  steps
(including   obtaining  warranties  from  the  vendors  thereof  in  respect  of
compliance)  to ensure that all  computer  software  will be designed to be used
prior to, during and after the calendar year 2000 AD and that such software will
operate  during  each such time  period,  without  error  relating to date data,
specifically  including any error relating to, or the product of, date data that
represents or references  different  centuries or more than one century,  except
where the  failure to be so  designed  or to so operate  would not have a Summit
Material Adverse Effect.

       Section   3.13.Beneficial   Ownership  of  Prime  Stock.  Summit  is  the
beneficial owner of 106,700 shares of Prime Stock on the date hereof.

                               COVENANTS OF PRIME

       Prime hereby covenants and agrees with Summit that:

       Section  4.01.Preparation of Registration  Statement and Applications for
Required  Consents.  Prime will  cooperate  with Summit in the  preparation of a
Registration  Statement on Form S-4 (the  "Registration  Statement") to be filed
with the SEC under the  Securities Act for the  registration  of the offering of
Summit  Stock  to be  issued  as  Reorganization  Consideration  and  the  proxy
statement-prospectus   constituting   part   of   the   Registration   Statement
("Proxy-Prospectus") that will be used by Prime to solicit shareholders of Prime
for approval of the Reorganization.  In connection therewith, Prime will furnish
all financial or other  information,  including using reasonable best efforts to
obtain  customary  consents,  certificates,  opinions of counsel and other items
concerning  Prime,  deemed  reasonably  necessary  by  counsel to Summit for the
filing or  preparation  for filing under the Securities Act and the Exchange Act
of the  Registration  Statement  (including  the  Proxy-Prospectus).  Prime will
cooperate  with Summit and provide  such  information  as may be  advisable  and
reasonably  available to Prime in obtaining  an order of  effectiveness  for the
Registration Statement,  appropriate permits or approvals under state securities
and  "blue  sky"  laws,  the  required  approval  under the BHCA of the Board of


                                       27
<PAGE>

Governors of 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
Reorganization  that would not have a Summit Material  Adverse Effect  following
the Reorganization (the "Required Consents").  Summit,  reasonably in advance of
making such filings, will provide Prime and its counsel a reasonable opportunity
to  comment  on such  filings  and  regulatory  applications  and will  give due
consideration  to any comments of Prime and its counsel  before  making any such
filing or application, and Summit will provide Prime 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. Prime covenants and
agrees  that  all  information  furnished  in  writing  by Prime  expressly  for
inclusion  in  the  Registration  Statement,   the  Proxy-Prospectus,   and  all
applications   to   appropriate   regulatory   agencies   for  approval  of  the
Reorganization  will comply in all  material  respects  with the  provisions  of
applicable law,  including the Securities Act and the Exchange Act and the rules
and  regulations  of the SEC  thereunder,  and  together  with  all  information
furnished in writing by Prime to Summit in connection  with  obtaining  Required
Consents  will not contain any untrue  statement of a material fact and will not
omit to state any material  fact  required to be stated  therein or necessary to
make the statements contained therein, in light of the circumstances under which
they were made, not misleading.  Prime will furnish to Fox-Pitt such information
about Prime  reasonably  available to it as Fox-Pitt may reasonably  request for
purposes of the opinion referred to in Section 8.07.

       Section 4.02.Notice of Adverse Changes. Prime will promptly advise Summit
in writing of (a) any event  occurring  subsequent to the date of this Agreement
which would  render any  representation  or warranty of Prime  contained in this
Agreement or the Prime  Schedules  or the  materials  furnished  pursuant to the
Post-Signing Document List (as defined in Section 4.09), if made on or as of the
date of such event or the Closing  Date,  untrue or  inaccurate  in any material
respect,  (b) any Prime Material Adverse Change,  (c) any inability or perceived
inability  of Prime to perform or comply  with the terms or  conditions  of this
Agreement,  (d) the  institution  or  threat of  institution  of  litigation  or
administrative proceedings involving Prime or any of its subsidiaries or assets,
which, if determined adversely to Prime or any of its subsidiaries, would have a
Prime Material  Adverse Effect or an adverse  material  effect on the ability of
the  parties  to  timely   consummate   the   Reorganization   and  the  related
transactions,  (e)  any  governmental  complaint,  investigation,   hearing,  or
communication  indicating that such litigation or  administrative  proceeding is
contemplated,  (f) any written notice of, or other communication  relating to, a
default or event  which,  with notice or lapse of time or both,  would  become a
default,  received by Prime or a  subsidiary  subsequent  to the date hereof and
prior to the Effective  Time,  under any  agreement,  indenture or instrument to
which  Prime or a  subsidiary  is a party or is subject and which is material to
the business,  operation or condition  (financial or otherwise) of Prime and its
subsidiaries  on a  consolidated  basis,  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  Reorganization.  Prime 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.  Prime will call a meeting of its
shareholders for the purpose of voting upon this Agreement,  the  Reorganization
and the  transactions  contemplated  hereby.  The meeting of Prime  shareholders
contemplated  by this Section 4.03 will be held as promptly as practicable  and,
in connection therewith,  will comply with the Pennsylvania Law and the Exchange
Act and all regulations  promulgated  thereunder governing  shareholder meetings
and proxy solicitations.  In connection with such meeting,  Prime shall mail the
Proxy-Prospectus  to Prime  shareholders  and use its reasonable best efforts to
obtain  shareholder  approval  of this  Agreement,  the  Reorganization  and the


                                       28
<PAGE>

transactions  contemplated hereby; provided,  however, that no director of Prime
shall be obligated  to take any action under this Section 4.03 in such  person's
capacity as a director  which such person  reasonably  believes on the advice of
counsel to be contrary to his fiduciary duty as a director.

       Section  4.04.Copies  of Filings.  Without  limiting  the  provisions  of
Section  4.01,  Prime  will  deliver to  Summit,  at least 48 hours  prior to an
anticipated date of filing or distribution or as soon thereafter as practicable,
all documents to be filed with the SEC or any bank regulatory authority or to be
distributed in any manner to the  shareholders  of Prime or to the news media or

written consent of Summit:

cash  dividends,  other than  dividends from  subsidiaries  of Prime to Prime or
other  subsidiaries of Prime except that Prime may declare,  set aside and pay a

Summit in connection with any such requirements imposed upon Summit or on any of
its subsidiaries in connection with the Reorganization.

       Section  4.11.Agreements  of  Affiliated  Shareholders.  Prime  agrees to
furnish to Summit,  not later than 10 business days prior to the date of mailing
of the  Proxy-Prospectus,  a writing  setting  forth the names of those  persons
(which will include all individual  and  beneficial  ownership of Prime Stock by
such persons and also identifies the manner in which all such beneficially owned
shares of Prime Stock are  registered on the stock record books of Prime) who in
the written  opinion of counsel to Prime (which opinion need not be furnished to
Summit),  constitute  all the  affiliates  of Prime for the purposes of Rule 145
under  the  Securities  Act (an  "Prime  Affiliate").  Prime  agrees  to use its
reasonable  best  efforts  (i) to cause  each Prime  Affiliate  to enter into an
agreement  effective  upon  the  execution  thereof,  satisfactory  in form  and
substance  to  Summit  and (y)  substantially  in the form of  Exhibit  D-1 with
respect to Affiliates  who are directors or officers of Prime or a subsidiary of
Prime,  or (z)  substantially  in the  form  of  Exhibit  D-2  with  respect  to
Affiliates  who are not  directors or officers of Prime or a subsidiary of Prime
(an "Affiliate  Agreement"),  and (ii) to furnish such  Affiliate  Agreements to
Summit  no later  than 5  business  days  prior to the  date of  mailing  of the
Proxy-Prospectus.

       Section  4.12.Loans  and  Leases to  Affiliates.  All  loans  and  leases

former  directors or executive  officers or their respective  related  interests

at the same interest rates as those prevailing for comparable  transactions with
others and shall not involve  more than the normal risk of  repayment or present
other unfavorable features.

       Section  4.13.Confidentiality.  All  information  furnished  by Summit to
Prime  or its  representatives  pursuant  hereto  shall be  treated  as the sole
property  of Summit and, if the  Reorganization  shall not occur,  Prime and its
representatives  shall return to Summit all of such written  information and all
documents,  notes,  summaries  or  other  materials  containing,  reflecting  or
referring  to,  or  derived  from,  such  information,   except  that  any  such
confidential  information or notes or abstracts therefrom presented to the Board
of Directors of Prime or any  committee  thereof for the purpose of  considering
this Agreement,  the Reorganization and the related transactions may be kept and
maintained by Prime with other records of Board, and Board  committee,  meetings
subject to a continuing  obligation of  confidentiality.  Prime shall, and shall
use  its  reasonable  best  efforts  to  cause  its   representatives  to,  keep
confidential all such information, and shall not directly or indirectly use such
information for any purposes other than the  performance of this Agreement.  The
obligation to keep such information  confidential  shall continue for five years
from the date the proposed  Reorganization  is abandoned and shall not apply to:
(i) any  information  which (x) was legally in Prime's  possession  prior to the
disclosure thereof by Summit, (y) was then generally known to the public, or (z)
was  disclosed  to  Prime  by a  third  party  not  bound  by an  obligation  of
confidentiality;  or (ii)  disclosures  made as  required  by law. It is further
agreed that if, in the absence of a protective  order or the receipt of a waiver
hereunder, Prime is nonetheless,  in the written opinion of its outside counsel,


                                       32
<PAGE>

compelled  to  disclose  information   concerning  Summit  to  any  tribunal  or
governmental  body or agency or else stand  liable for  contempt or suffer other
censure or penalty,  Prime may disclose  such  information  to such  tribunal or
governmental  body or agency  without  liability  hereunder  and shall so notify
Summit in advance to the extent practicable. This Section 4.13 shall survive any
termination of this Agreement.

       Section 4.14.Dividends. Prime will coordinate with Summit the declaration
of any dividends and the record and payment dates thereof so that the holders of
Prime Stock will not be paid two  dividends for a single  calendar  quarter with
respect  to their  shares of Prime  Stock and any  shares of Summit  Stock  they
become entitled to receive in the Reorganization or fail to be paid one dividend
in each calendar  quarter between the date hereof and the Effective Time.  Prime
will notify Summit at least five  business  days prior to any proposed  dividend
declaration date.

       Section 4.15.Acquisition  Proposals.  Prime agrees that neither Prime nor
any of its  subsidiaries  nor any of the  respective  officers and  directors of
Prime or its subsidiaries  shall, and Prime shall direct and use its best effort
to cause its  employees,  affiliates,  agents  and  representatives  (including,
without  limitation,  any  investment  banker,  broker,  financial or investment
advisor,  attorney or accountant  retained by Prime 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, 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,

defined  to be any  offer,  including  an  exchange  offer or tender  offer,  or
proposal concerning a merger,  consolidation,  or other business  combination or
takeover  transaction  involving  Prime  or  any  of  its  subsidiaries  or  the
acquisition  of any assets  (otherwise  than as  permitted  by Section  4.05) or
securities of Prime or any of its subsidiaries. Prime will immediately cease and
cause to be terminated any existing activities,  discussion or negotiations with
any parties  conducted  heretofore  with respect to any of the foregoing.  Prime
will take the necessary steps to inform the individuals or entities  referred to
in the first sentence hereof of the obligations  undertaken in this Section.  In
addition,  Prime will notify Summit by telephone 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 Prime or any of its  subsidiaries  or assets by another
party,  and  will   immediately   deliver  as  soon  as  possible  by  facsimile
transmission,  receipt acknowledged,  to the Summit officer notified as required
above a copy of any document  relating  thereto promptly after any such document
is received by Prime.

       Section 4.16 Tax Opinion Certificates. Prime shall execute and deliver to
Thompson  Coburn any tax  opinion  certificate  reasonably  required by Thompson
Coburn in  connection  with the  issuance  of the Tax  Opinions  (as  defined at

Statement  and as of the Closing Date (and as of the date the Closing  occurs if
different  than the  Closing  Date),  and Prime  shall use its  reasonable  best
efforts to cause each of its executive  officers,  directors and holders of five
percent (5%) or more of outstanding Prime Stock (including  shares  beneficially
held) to execute  and deliver to  Thompson  Coburn any tax  opinion  certificate
reasonably required by Thompson Coburn in connection with the issuance of one or
more  of  the  Tax  Opinions,  dated  as of the  date  of  effectiveness  of the
Registration  Statement  and as of the  Closing  Date  (and as of the  date  the

subsidiaries  has taken or will take all requisite  action  (including,  without
limitation,  the  making of claims and the giving of  notices)  pursuant  to its
directors'  and  officers'   liability   insurance   policy  or  policies  ("D&O
Insurance")  in order to  preserve  all rights  thereunder  with  respect to all
matters  (other than matters  arising in connection  with this Agreement and the
transactions contemplated hereby) occurring prior to the Effective Time that are
known to Prime.  Prime shall renew any  existing  D&O  Insurance or purchase any
"discovery period" D&O Insurance provided for thereunder at Summit's request.

       Section 4.18.Conforming Entries.

       (a)  Notwithstanding  that Prime believes that Prime and its subsidiaries
have  established  reserves and taken all provisions for possible loan and lease
losses required by generally accepted accounting principles and applicable laws,
rules and regulations,  Prime recognizes that Summit may have adopted  different
loan, accrual and reserve policies  (including loan classification and levels of
reserves for possible  loan and lease  losses).  From and after the date of this
Agreement,  Prime and Summit shall  consult and  cooperate  with each other with
respect to conforming  the loan,  accrual and reserve  policies of Prime and its
subsidiaries  to those policies of Summit,  as specified in each case in writing
to Prime, based upon such consultation and as hereinafter provided.

       (b) In  addition,  from and after the date of this  Agreement,  Prime and
Summit shall consult and cooperate  with each other with respect to  determining
appropriate  accruals,  reserves and charges for Prime to establish  and take in
respect of excess equipment  write-off or write-down of various assets and other
appropriate charges and accounting  adjustments taking into account the parties'
business plan following the Reorganization, as specified in each case in writing
to Prime, based upon such consultation and as hereinafter provided.

       (c) Prime and Summit  shall  consult and  cooperate  with each other with
respect to determining  the amount and the timing for  recognizing for financial
accounting purposes Prime's expenses of the Reorganization and the restructuring
charges,  if  any,  related  to  or  to  be  incurred  in  connection  with  the
Reorganization.

       (d) With respect to clauses (a) through (c) of this Section 4.18,  (i) it
is the objective of Prime and Summit that such reserves,  accruals,  charges and
divestitures,  if any, to be taken shall be consistent  with generally  accepted
accounting  principles,  and  (ii)  Prime  shall  not  be  obligated  to  make a
particular  conforming  entry if the  particular  entry is not  capable of being
reversed  upon a  termination  of this  Agreement  or if the entry  would have a
material adverse effect on Prime.

       Section 4.19  Cooperation with Policies and Procedures.  Prime,  prior to
the Effective  Time,  shall (i) consult and cooperate with Summit  regarding the
implementation  of those policies and  procedures  established by Summit for its
governance and that of its subsidiaries and not otherwise  referenced in Section
4.18 of this Agreement,  including, without limitation,  policies and procedures
pertaining to the accounting,  asset/liability management,  audit, credit, human
resources,  treasury and legal functions,  and (ii) at the reasonable request of
Summit,  conform Prime's  existing  policies and procedures in respect  thereof,
provided  that Prime shall not be required to conform a policy or procedure  (y)
if such would cause Prime or any of its  subsidiaries  to be in violation of any
law, rule,  regulation or requirement of any governmental  regulatory  authority
having  jurisdiction over Prime or any of its subsidiaries  affected thereby, or
(z)  if  such  conforming  change  is  not  capable  of  being  reversed  upon a
termination  of this  Agreement or if the change  would have a material  adverse
effect on Prime.

       Section 4.20  Environmental  Reports.  Prime shall disclose to Summit all
matters of the types  described  in Section  2.22 hereof  which Prime would have
been  required to disclose to Summit on the date hereof if known to Prime on the
date  hereof,  as such  become  known to Prime  between  the date hereof and the
Effective Time. In addition,  Summit may at its expense perform,  or cause to be
performed, a phase one environmental investigation,  an asbestos survey, or both
of the foregoing,  (i) within 90 days following the date of this  Agreement,  on
all real property owned,  leased or operated by Prime or any of its subsidiaries
as of the date of this  Agreement  (but  excluding  space in retail  or  similar
establishments  leased by Prime for  automatic  teller  machines  or leased bank
branch facilities where the space leased by Prime comprises less than 20% of the
total  space  leased to all tenants of such  property),  and (ii) within 15 days
after being  notified by Prime of the  acquisition or lease of any real property
by it or its subsidiaries after the date of this Agreement, on the real property
so acquired or leased (but excluding  space in retail or similar  establishments
leased by Prime for automatic  teller machines or leased bank branch  facilities
where  the  space  leased by Prime  comprises  less than 20% of the total  space
leased  to all  tenants  of  such  property).  If the  results  of a  phase  one
investigation (whether requested by Prime or Summit) indicate, in the reasonable
opinion of Summit, that additional investigation is warranted, Summit may at its
expense,  within 15 days  after  receipt  of the  particular  phase one  report,
perform or cause to be  performed a phase two  investigation  on the property or
properties deemed by Summit to warrant such additional study or notify Prime and
an  environmental  consulting  firm  within  15 days  after the  receipt  of the
particular  phase one  report  that the  environmental  consulting  firm  should
promptly commence a phase two investigation.  If the cost of taking all remedial
or other  corrective  actions and measures (as  required by  applicable  law, as
recommended  or  suggested  by phase  one or  phase  two  investigation  reports
(without  regard to who requested such reports) or as may be prudent in light of
serious life, health or safety concerns),  if any, is in the aggregate in excess
of $3,000,000,  as reasonably  estimated by an environmental expert retained for
such purpose by Summit at its sole  expense,  or if the cost of such actions and
measures  cannot be so reasonably  estimated by such expert to be such amount or
less  with any  reasonable  degree of  certainty,  Summit  shall  have the right
pursuant to Section 9.02(d)(3) of this Agreement to terminate this Agreement.

       Section  4.21 Best  Efforts to Ensure  Pooling.  Prime agrees to use, and
agrees to cause each of its  subsidiaries  to use, its and their best efforts to
cause  the  Reorganization  to  qualify  for   pooling-of-interests   accounting
treatment.

                               COVENANTS OF SUMMIT

       Summit hereby covenants and agrees with Prime that:

       Section  5.01.Approvals and  Registrations.  Based on such assistance and
cooperation  of Prime as Summit shall  reasonably  request,  Summit will use its
reasonable  best efforts to prepare and file (a) with the SEC, the  Registration
Statement,  (b) with the Federal  Reserve Board,  an application for approval of
the Reorganization, and (c) with the NYSE, an application for the listing of the
shares of Summit Stock  issuable  upon the  Reorganization,  subject to official
notice  of  issuance,  and  (d)  with  any  state  regulatory  authority  having
jurisdiction  over  the  Reorganization,   applications  for  such  consents  or
approvals as may be required for consummation of the  transactions  contemplated
by this  Agreement,  except that Summit shall have no  obligation  to file a new
registration  statement  or  a  post-effective  amendment  to  the  Registration
Statement  covering any reoffering of Summit Stock by Prime  Affiliates.  Summit
covenants and agrees that all  information  furnished by Summit for inclusion in


                                       35
<PAGE>

the  Registration  Statement,  the  Proxy-Prospectus,  and all  applications and
submissions for the Required  Consents will comply in all material respects with
the provisions of applicable law,  including the Securities Act and the Exchange
Act and the rules and  regulations of the SEC and the Federal  Reserve Board and
will not contain any untrue  statement  of a material  fact and will not omit to
state any material fact  required to be stated  therein or necessary to make the
statements  contained  therein,  in light of the circumstances  under which they
were made, not  misleading.  Summit will use its reasonable best efforts to seek
the effectiveness of the Registration Statement. Summit will furnish to Fox-Pitt
such  information  about  Summit  reasonably  available  to it as  Fox-Pitt  may
reasonably request for purposes of the opinion referred to in Section 8.07.

       Section 5.02.Notice of Adverse Changes. Summit will promptly advise Prime
in writing of (a) any event  occurring  subsequent to the date of this Agreement
which would render any  representation  or warranty of Summit  contained in this
Agreement or the Summit Schedules, if made on or as of the date of such event or
the Closing Date, untrue or inaccurate in any material  respect,  (b) any Summit
Material Adverse Change,  (c) any inability or perceived  inability of Summit to
perform  or  comply  with the terms or  conditions  of this  Agreement,  (d) the
institution or threat of institution of litigation or administrative  proceeding
involving Summit or its assets which, if determined  adversely to Summit,  would
have a Summit  Material  Adverse  Effect  or a  material  adverse  effect on the
parties'  ability  to  consummate  the  Reorganization,   (e)  any  governmental
complaint,  investigation,  or hearing  or  communication  indicating  that such
litigation or administrative proceeding is contemplated,  (f) any written notice
of, or other communication relating to, a default or event which, with notice or
lapse of time or both, would become a default,  received by Summit subsequent to
the date hereof and prior to the Effective Time, under any agreement,  indenture
or  instrument to which Summit is a party or is subject and which is material to
the business,  operation or condition (financial or otherwise) of Summit and its
subsidiaries  on a  consolidated  basis,  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 Reorganization.  Summit agrees that the delivery of such
notice  shall  not  constitute  a waiver  by Prime of any of the  provisions  of
Articles VI or VIII.

       Section  5.03.Copies of Filings.  Summit shall promptly  provide to Prime
and its counsel copies of the application  filed with the Federal Reserve Board,
all  reports  filed  by it with  the SEC on  Forms  10-Q,  8-K and  10-K and all
documents to be distributed in any manner to the shareholders of Summit.

       Section 5.04.Further  Actions.  Summit will: (a) execute and deliver such
instruments and take such other actions as Prime may reasonably require to carry
out the intent of this Agreement;  (b) use its reasonable best efforts to obtain
consents of all third parties and  governmental  bodies  necessary or reasonably
desirable  for  the  consummation  of  the  transactions  contemplated  by  this
Agreement;  (c) diligently  support this Agreement in any proceeding  before any
regulatory  authority  whose  approval of any of the  transactions  contemplated
hereby  is  required  or  reasonably  desirable  or  before  any  court in which
litigation  in  respect  thereof is  pending;  and (d) use its  reasonable  best
efforts so that the other  conditions  precedent to the obligations of Prime set
forth in Articles VI and VIII hereof are satisfied.

       Section 5.05.Applicable Laws. Summit will use its reasonable best efforts
to comply promptly with all  requirements  which federal or state law may impose
on Summit with respect to the  Reorganization  and will promptly  cooperate with
and  furnish  information  to Prime  in  connection  with any such  requirements
imposed  upon  Prime  or on any of  its  subsidiaries  in  connection  with  the



                                       36
<PAGE>

Reorganization.

       Section 5.06.Unpaid Prime Dividends.  By virtue of the Reorganization and
without  further action on anyone's part,  Summit shall assume the obligation of
Prime to pay dividends, if any, on Prime Stock which have a record date prior to
the Effective Time but which are not payable until after the Effective Time.

       Section  5.07.Cooperation.  Until the Effective Time, Summit will provide
such  information  with respect to its business  affairs and properties as Prime
from  time to time  may  reasonably  request,  and  will  cause  its  managerial
employees,  counsel and independent certified public accountants to be available
on reasonable  request to answer questions of Prime's  representatives  covering
the business and affairs of Summit or any of its subsidiaries.

       Section  5.08.Confidentiality.  All  information  furnished  by  Prime to
Summit or its  representatives  pursuant  hereto  shall be  treated  as the sole
property of Prime and,  if the  Reorganization  shall not occur,  Summit and its
representatives  shall return to Prime all of such written  information  and all
documents,  notes,  summaries  or  other  materials  containing,  reflecting  or
referring  to,  or  derived  from,  such  information,   except  that  any  such
confidential  information or notes or abstracts therefrom presented to the Board
of Directors of Summit or any committee  thereof for the purpose of  considering
this Agreement,  the Reorganization and the related transactions may be kept and
maintained by Summit with other records of Board, and Board committee,  meetings
subject to a continuing  obligation of confidentiality.  Summit shall, and shall
use  its  reasonable  best  efforts,  to  cause  its  representatives  to,  keep
confidential all such information, and shall not directly or indirectly use such
information for any purposes other than the  performance of this Agreement.  The
obligation to keep such information  confidential  shall continue for five years
from the date the proposed  Reorganization  is abandoned and shall not apply to:
(i) any information  which (x) was legally in Summit's  possession  prior to the
disclosure  thereof by Prime, (y) was then generally known to the public, or (z)
was  disclosed  to  Summit  by a third  party  not  bound  by an  obligation  of
confidentiality;  or (ii)  disclosures  made as  required  by law. It is further
agreed that if, in the absence of a protective  order or the receipt of a waiver
hereunder,  Summit  is  nonetheless,  in the  written  opinion  of its  counsel,
compelled  to  disclose   information   concerning  Prime  to  any  tribunal  or
governmental  body or 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
Prime 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 Securities 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(a) 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.


                                       37
<PAGE>

       (a) Summit shall  indemnify  persons who served as directors and officers
of Prime or any subsidiary of Prime 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 and the certificate or articles of incorporation  and by-laws of Prime or
the  applicable  subsidiary  of  Prime,  all as in  effect  on the  date of this
Agreement and to the extent  permitted by law, and Summit shall advance expenses
in  matters  that may be  subject  to  indemnification  in  accordance  with its
Restated  Certificate of Incorporation and By-Laws in effect on the date of this
Agreement and any applicable provisions of law.

       (b) Subject to Prime's obligation set forth at Section 4.17: For a period
of six (6) years after the Effective  Time,  Summit will use its reasonable best
efforts to provide to the persons who served as  directors  or officers of Prime
or any  subsidiary of Prime 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 Prime 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
reasonable 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 Prime and its  subsidiaries  referred to herein are
intended to be third party  beneficiaries  and shall be  enforceable by the such
persons and their heirs and  representatives.  Summit's  obligations  under this
Section 5.10 shall survive the Effective Time.

       Section  5.11.Employee  Matters.  After the Effective Time, Summit may in
its  discretion  maintain,  terminate,  merge or  dispose  of the  Prime  Plans;
provided,  however,  that any action taken by Summit shall comply with ERISA and
any other applicable laws, including laws regarding the preservation of employee
pension benefit plan benefits and, provided further,  that if Summit maintains a
defined  contribution  plan,  defined  benefit  plan or health and welfare  plan
available to all its employees  generally which is similar to a Prime Plan which
is,  respectively,  a defined  contribution plan, defined benefit plan or health
and welfare plan available to all Prime employees generally, then, if such Prime
Plan is terminated by Summit or is otherwise rendered inactive by Summit, Summit
shall offer to the former  employees of Prime affected by such plan  termination
or cessation of activity the  opportunity  to participate in the similar plan of
Summit.

       Section 5.12.Tax Opinion  Certificates.  Summit shall execute and deliver
to Thompson Coburn any tax opinion  certificate  reasonably required by Thompson
Coburn in connection with the issuance of the Tax Opinions, dated as of the date
of effectiveness  of the Registration  Statement and as of the Closing Date (and
as of the date the Closing occurs if different than the Closing Date).

all the following  conditions,  compliance with which or the occurrence of which
may only be  waived  in whole  or in part in  writing  by  Summit  and  Prime in
accordance with Section 10.09:

       Section  6.01.Receipt of Required  Consents.  Summit and Prime shall have
received  the  Required  Consents;  the  Required  Consents  shall  not,  in the
reasonable  opinion of Summit,  contain  restrictions or limitations which would
materially adversely affect the financial condition of Summit after consummation
of the Reorganization;  the Required Consents and the transactions  contemplated
hereby shall not be contested  by any federal or state  governmental  authority;
and the Required Consents needed for the Reorganization shall have been obtained

shall have been  declared  effective  by the SEC; no stop order  suspending  the
effectiveness of the Registration Statement shall have been issued and remain in
effect;  and no proceeding for that purpose shall have been initiated or, to the
knowledge of Summit or Prime, shall be contemplated or threatened by the SEC.

occurs if different than the Closing Date), Summit and Prime shall have received
from Thompson Coburn an opinion addressed to Prime,  Summit and all shareholders
of Prime (the "Tax Opinion"),  reasonably  satisfactory in form and substance to
Prime and Summit,  to the effect that (a) the  Reorganization  will constitute a
tax-free  reorganization  within the meaning of Section  368(a) of the Code, (b)

receive  solely Summit Stock in the  Reorganization  will not recognize  gain or
loss for  federal  income  tax  purposes,  (c) the  basis of such  Summit  Stock
(including any fractional share for which cash is received) will equal the basis

include  the  holding  period  of the Prime  Stock  for  which it is  exchanged,

thereof at the Effective Time.

       In addition,  no condition or set of facts or  circumstances  shall exist
which will  either  (y)  preclude  any of the  parties  to this  Agreement  from
satisfying the terms or conditions of, or assumptions  made in, the Tax Opinion,
as the case may be, or (z) result in any of the factual assumptions contained in
the Tax Opinion being untrue.

       Section  6.04.Absence  of Litigation.  No  investigation  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 body or authority,

Agreement and the transactions contemplated hereby by the requisite vote;

              (2) a material breach of a warranty,  representation,  covenant or
agreement made by the other party in this Agreement shall have occurred and such
breach has not been  cured,  or is not  capable of being  cured,  within 30 days

              (4) the Closing is not  consummated  on or before the later of (i)
January 3, 2000,  unless the failure of such occurrence shall be due solely to a
Material  Breach by the party seeking to terminate this Agreement or the failure
of such party to fulfill a condition to Closing provided for herein, or (ii) the
Scheduled  Date,  if the last  event  required  to occur  pursuant  to the first
sentence  of  Section  9.01 for the  setting  of the  Scheduled  Date shall have

the conditions to its obligation to close set forth in Article VI shall not have
been met, the parties shall conduct the Closing as promptly as practicable after
all such  conditions  have been  satisfied.  In the event the  failure of such a
condition is due to one or more Material  Breaches,  the Board of Directors of a
party not in Material  Breach may,  during the period any such  Material  Breach
remains  uncured,  terminate  this  Agreement by giving  written  notice of such
termination to the other party.

satisfied,  and (ii) the Board of Directors of such party may, during the period
the failed  condition  continues,  terminate  this  Agreement by giving  written
notice of such  termination  to the other  party  unless  such party  itself has
failed to satisfy a condition to the other party's  Closing  obligation or is in
Material Breach.

       (d) The Board of Directors of Summit may terminate this Agreement:

              (1) at any time if Prime does not  execute  and deliver the Option
Agreement by the day immediately following the date hereof;

              (2)  at any  time  prior  to the  meeting  of  Prime  shareholders
contemplated  by  Section  4.03,  if the Board of  Directors  of Prime  fails to
recommend   approval  of  this  Agreement  and  the   Reorganization  and  other
transactions  contemplated hereby in the Proxy-Prospectus  ("Recommendation") or
withdraws,  modifies or changes,  or votes to  withdraw,  modify or change,  its
Recommendation  or its intention to make the  Recommendation  as represented and
warranted at Section 2.08; and

              (3) as provided at Section 4.20.

STRICTLY CONFIDENTIAL



February 17, 1999



The Board of Directors
Prime Bancorp, Inc.
7111 Valley Green Road
Fort Washington, Pennsylvania 19034



Gentlemen:


Fox-Pitt, Kelton Inc. ("Fox-Pitt, Kelton") understands that Prime Bancorp, Inc.
("Prime") and Summit Bancorp ("Summit") propose to enter into an agreement and
plan of merger dated as of February 17, 1999 (the "Merger Agreement"), which
will provide for, among other things, the acquisition of Prime by Summit
through either the merger of Prime with and into Summit or into a wholly owned
subsidiary of Summit, or the merger of a wholly owned subsidiary of Summit into
Prime (the "Merger"). As set forth in the Merger Agreement, and subject to
certain exceptions set forth therein, at the effective time of the Merger, each
issued and outstanding share of common stock of Prime, par value $1.00 per
share (the "Prime Common Stock"), shall be converted into the right to receive
0.675 shares (the "Exchange Ratio") of common stock of Summit, par value $0.80
per share (the "Summit Common Stock"). In connection with the Merger, the
parties will enter into a stock option agreement ("Option Agreement"), pursuant
to which Prime will grant Summit an option to acquire a number of shares
(subject to adjustment), which if issued would represent no more than 9.9% of
the total number of outstanding shares of Prime, which option is exercisable
upon the occurrence of certain specified events set forth therein. In addition,
as provided in the Option Agreement, in the event the option is exercised by
Summit, Prime will also pay additional cash consideration of $5 million to
Summit. The terms and conditions of the Merger are more fully set forth in the
Merger Agreement.

You have asked for Fox-Pitt, Kelton's opinion as to whether the Exchange Ratio
is fair, from a financial point of view, to the holders of Prime Common Stock.

In arriving at the opinion set forth below, Fox-Pitt, Kelton has, among other
things:

a) reviewed and analyzed certain publicly available financial statements for
   Prime and Summit and financial information made available to us by the
   management of Prime and Summit;


b) analyzed certain internal financial statements, including financial
   projections, and other financial and operating data prepared by the
   management of Prime;


c) discussed the past, present and future operations, financial condition and
   prospects of Prime and Summit with the management of Prime and Summit,
   respectively;


d) reviewed the stock price performance and trading activity of Prime Common
   Stock and Summit Common Stock;


e) compared the financial performance and condition of Prime and Summit with
   that of certain other comparable publicly traded companies;


f) reviewed the financial terms, to the extent publicly available, of certain
   merger and acquisition transactions comparable, in whole or in part, to the
   Merger;


g) reviewed and discussed with the management of Prime and Summit the strategic
   objectives of the Merger and certain other benefits of the Merger;


h) reviewed the Merger Agreement and the Option Agreement; and

i) performed such other analyses as we have deemed appropriate.

                                       B-1
<PAGE>


Fox-Pitt, Kelton has assumed and relied upon, without independent verification,
the accuracy and completeness of all of the financial and other information it
has reviewed for the purposes of providing this opinion, and we have not
assumed any responsibility for independent verification of such information.
Fox-Pitt, Kelton has not assumed any responsibility for any independent
valuation or appraisal of the assets and liabilities of Prime nor have we been
furnished with any such valuation or appraisal. Fox-Pitt, Kelton has not
assumed any responsibility for reviewing loan files or visiting branch
locations. With respect to the financial projections, Fox-Pitt, Kelton has
assumed that they have been reasonably prepared by the management of Prime on
bases reflecting the best currently available estimates and judgments of the
future financial performance of Prime. We express no view as to such
projections or the assumptions on which they are based. We have assumed that
the Merger described in the Merger Agreement will be consummated on the terms
set forth therein without material waiver or modification. Fox-Pitt, Kelton's
opinion is necessarily based upon economic, market and other conditions as they
exist and can be evaluated on February 16, 1999.

In connection with the preparation of this opinion, we were not authorized by
the Board of Directors to solicit, nor have we solicited, third party
indications of interest for the acquisition of all or part of Prime.

In the normal course of its investment banking business, Fox-Pitt, Kelton is
regularly engaged in the valuation of bank and bank holding company securities
in connection with acquisitions, negotiated underwritings, secondary
distributions of listed and unlisted securities, private placements and
valuations for various other purposes. As specialists in the securities of
banking companies, Fox-Pitt, Kelton has experience in, and knowledge of, the
valuation of such enterprises.

In the normal course of its business, Fox-Pitt, Kelton may trade equity
securities of Prime and Summit for its own account and for the accounts of
customers and, accordingly, may at any time hold a long or short position in
such securities. We have acted as financial advisor to Prime in connection with
the Merger, have received a fee in connection with our engagement, will receive
an additional fee upon the execution of the Merger Agreement and will receive a
final fee upon the closing of the Merger.

It is understood that this letter is solely for the information of the Board of
Directors of Prime and is not intended to confer any rights or remedies upon
any other entity or persons, and may not be used for any other purpose without
our prior written consent, except for inclusion in a proxy or information
statement related to the Merger that we have had an opportunity to review. This
opinion does not constitute a recommendation to any holder of Prime Common
Stock as to how such shareholder should vote on the Merger.

Based upon and subject to the foregoing, Fox-Pitt, Kelton is of the opinion
that, on the date hereof, the Exchange Ratio is fair, from a financial point of
view, to the holders of Prime Common Stock.


Very truly yours,





FOX-PITT, KELTON INC.

                   PRIME 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 18th day of  February,  1999
(this   "Agreement"),   between  Summit  Bancorp.,   a  New  Jersey  corporation
("Grantee"), and Prime Bancorp, Inc., a Pennsylvania corporation ("Issuer").

                                   WITNESSETH:

         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 17th day of
February,  1999  (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 an option and to pay a breakup
fee on the terms set forth herein.

         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; Breakup Fee.

         (a)  Issuer  hereby  grants to Grantee  an  unconditional,  irrevocable
option (the "Option") to purchase,  subject to the terms hereof, up to 1,087,498
fully paid and  nonassessable  shares of the common  stock,  par value $1.00 per
share,  of Issuer  ("Common  Stock") at a price  equal to $18.00 per share (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 9.9% 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) In the event the Option becomes  exercisable  and Summit  exercises
the Option in full, Prime shall pay to Summit  $5,000,000 (the "Breakup Fee") in
accordance with Section 2.

         SECTION 2.        Exercise of Option; Payment of Breakup Fee.

         (a) Grantee may exercise the Option in whole at any 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)(2) or Sections 9.02 (c) or
(d)(2)  thereof  (with  the  understanding  that  Section  9.02(d)(2)  does  not
encompass the  situation  where the Board of Directors of Prime  recommends  the
Reorganization  but the  shareholders  of Prime at the meeting held  pursuant to
Section 4.03 of the Merger  Agreement  fail to approve the  Reorganization),  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)(2) or Sections 9.02 (c)
or  (d)(2)  thereof  (with  the  same  understanding  with  respect  to  Section
9.02(d)(2) as set forth in clause (ii) above),  and provided  further,  that any
purchase  of Common  Stock  upon  exercise  of the  Option

<PAGE>
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 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 after the date hereof  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);  except that  notwithstanding  the foregoing  shareholders of Prime
described in the proxy  statement of Prime dated March 18, 1998 as  beneficially
owning 5% or more of the  outstanding  common  stock of Prime and  directors  of
Prime  shall each be  permitted  to  acquire  beneficial  ownership  of up to an
additional 2% of the  outstanding  Common Stock in addition to their  respective
current holdings;

                  (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);

<PAGE>


                  (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) 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;

                  (ii) The occurrence of the event described in Section 2(b)(i),
except that for purposes of determining  whether the event  described in Section
2(b)(i)  has  occurred  for  purposes  of this  subsection  (ii) the  percentage
referred to in clauses (x) and (y) of the definition of Acquisition  Transaction
which is incorporated into said Section 2(b)(i) shall be 25%; or

                  (iii) the  meeting of Prime  shareholders  required by Section
4.03 of the  Merger  Agreement  shall  not  have  been  called  by the  Board of
Directors of Issuer 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  Reorganization  the
recommendation  of  Issuer's  Board of  Directors  with  respect  to the  Merger
Agreement as set forth therein, in each case after an Extension Event.

         (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) 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 (ii) 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
Aggregate Option Price (as defined in this Section 2(f) below) 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. "Aggregate Option
Price" means the amount  obtained by  subtracting  (b) from (a) where (b) is the
Breakup Fee and (a) is the amount  obtained by multiplying  the number of shares
with  respect to which the Option is being  exercised by the Option  Price.  The
terms of this Section 2(f) are  specifically  intended not to provide a discount
from the fair market  value of Issuer's  Common  Stock on the date the Option is
granted and this Agreement signed,  but instead to provide for a procedure which
(i) aligns Grantee's right to receive the Breakup Fee with its right to exercise
the Option  and (ii)  offsets  the  obligation  of Grantee to pay the  aggregate
purchase  price  provided for in connection  with an exercise of the Option with
the  obligation  of Issuer to pay the Breakup Fee and  thereby  facilitates  and
assures  Grantee's  receipt of the benefits of this Agreement  which the parties
have mutually agreed Grantee is entitled to on the terms provided for herein.

         (g) At such closing,  simultaneously with the delivery of the Aggregate
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.

         (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 Prime Bancorp, Inc. ("Issuer") dated as of the 18th day of
         February,  1999. 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 an  opinion  of  counsel,  in form  and  substance
satisfactory  to  Issuer,  to the  effect  that the  transfer  qualifies  for an
exemption from the Securities Act and applicable  state securities laws and such
legend is not required for purposes of the Securities  Act and applicable  state
securities  laws;  (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
Aggregate  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


                                      -4-
<PAGE>
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 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 articles 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.  ss.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.  In  conjunction  with or  following an
assignment  permitted by Section 11 hereunder,  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, 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 any  option  or  right  under a Prime  Stock
Compensation Plan or an exercise of the Option),  the number of shares of Common
Stock  subject to the Option  shall be increased so it equals 9.9% 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 or
subject to or issued pursuant to options  outstanding on the date hereof under a
Prime Stock Compensation Plan).

         (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.

                                      -5-
<PAGE>

         (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
registration  statement on such form as is available  and the Issuer is eligible
to use under the Securities Act relating to a delayed or continuous offering (as
contemplated  by Rule 415 of the SEC under the  Securities  Act or any successor
rule or regulation) (a "shelf registration") 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
135 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  one such  registration
(notwithstanding the number of Grantees).  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 one registration  pursuant to this
Section 6 by reason of the fact that there  shall be more than one  Grantee as a
result of an assignment permitted by Section 11 hereof.

         (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  of the  Company  (but not any
Grantee),  printing  expenses and the costs of special  audits or "cold comfort"
letters, expenses of underwriters,  excluding discounts and commissions, and the
reasonable  fees and expenses of any  necessary  special  experts) in connection
with  the  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

                                      -6-
<PAGE>
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, 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

                                      -7-
<PAGE>
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 shall pay to Grantee the Breakup
Fee; 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 by a third party 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 average of the last
sale prices for a share of Common Stock during 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 and the Breakup Fee or to the Owner the Option Share  Repurchase  Price or
with respect to the Option Repurchase Price or the Option Share Repurchase Price
the portion thereof that Issuer is not then prohibited from so delivering  under
applicable law and regulation.

         (c) Each of Issuer and Grantee  hereby  undertake 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 shall deliver to the Grantee the Breakup Fee as provided in
Section 7(b) above,  and thereafter  shall 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,

                                      -8-
<PAGE>
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  surrendered
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 Acquisition  Transaction,  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 provide for payment of the Breakup Fee
on terms as  identical  as  possible  to those  provided  for herein  unless the
Breakup Fee has been paid under the  circumstances  described  in Section  7(c).
Furthermore,  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 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



                                      -9-
<PAGE>
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  (including  terms  governing  the  Breakup  Fee as provided in the first
sentence of Section 8(b) above),  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 9.9% 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 9.9% 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 12
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

                                      -10-
<PAGE>
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 12
months  after the  related  Notice  Date due to the  failure  to obtain any such
required  approval,  Grantee  shall  be  entitled  to  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
institutions the deposits of which are insured by the Federal Deposit  Insurance
Corporation 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  articles  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 material 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 in whole or in part to one
or  more  subsidiaries  directly  or  indirectly  wholly-owned  by  Grantee  (as
"indirect"  ownership  is defined at  Section  2.01(a) of the Merger  Agreement)
(other than director  qualifying shares, if any) . 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

                                      -11-
<PAGE>

Grantee  hereunder  shall bear the restrictive  legend at the beginning  thereof
substantially as follows:

         "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  Prime  Bancorp,  Inc.
         ("Issuer")  dated as of the 18th day of February,  1999. 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 the transfer
qualifies  for an  exemption  from  the  Securities  Act  and  applicable  state
securities  laws and such legend is not required for purposes of the  Securities
Act and applicable  state  securities laws; (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.

                                      -12-
<PAGE>

         SECTION 16.  Governing  Law.  This  Agreement  shall be governed by and
construed in accordance with the laws of the Commonwealth of Pennsylvania.

         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.

         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 Section 6
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.

        available without regard to the exception provided in that paragraph in
        the case of:

      (i)  Shares converted by a plan if the shares are not converted solely
            into shares of the acquiring, surviving, new or other corporation
            or solely into such shares and money in lieu of fractional shares.

      (ii)  Shares of any preferred or special class unless the articles, the
            plan or the terms of the transaction entitle all shareholders of
            the class to vote thereon and require for the adoption of the plan
            or the effectuation of the transaction the affirmative vote of a
            majority of the votes cast by all shareholders of the class.


      (iii) Shares entitled to dissenters rights under section 1906(c)
            (relating to dissenters rights upon special treatment).


    (3) The shareholders of a corporation that acquires by purchase, lease,
        exchange or other disposition all or substantially all of the shares,
        property or assets of another corporation by the issuance of shares,
        obligations or otherwise, with or without assuming the liabilities of
        the other corporation and with or without the intervention of another
        corporation or other person, shall not be entitled to the rights and
        remedies of dissenting shareholders provided in this subchapter
        regardless of the fact, if it be the case, that the acquisition was
        accomplished by the issuance of voting shares of the corporation to be
        outstanding immediately after the acquisition sufficient to elect a
        majority or more of the directors of the corporation.


(c) Grant of optional dissenters rights. The bylaws or a resolution of the
board of directors may direct that all or a part of the shareholders shall have
dissenters rights in connection with any corporate action or other transaction
that would otherwise not entitle such shareholders to dissenters rights.


(d) Notice of dissenters rights. Unless otherwise provided by statute, if a
proposed corporate action that would give rise to dissenters rights under this
subpart is submitted to a vote at a meeting of shareholders, there shall be
included in or enclosed with the notice of meeting:


  (1) a statement of the proposed action and a statement that the shareholders
         have a right to dissent and obtain payment of the fair value of their
         shares by complying with the terms of this subchapter; and


  (2) a copy of this subchapter.


(e) Other statutes. The procedures of this subchapter shall also be applicable
to any transaction described in any statute other than this part that makes
reference to this subchapter for the purpose of granting dissenters rights.


(f) Certain provisions of articles ineffective. This subchapter may not be
    relaxed by any provision of the articles.


(g) Cross references. See sections 1105 (relating to restriction on equitable
    relief), 1904 (relating to de facto transaction doctrine abolished) and
    2512 (relating to dissenters rights procedure).

Section1572. Definitions.


     The following words and phrases when used in this subchapter shall have
the meanings given to them in this section unless the context clearly indicates
otherwise:


     "Corporation." The issuer of the shares held or owned by the dissenter
before the corporate action or the successor by merger, consolidation,
division, conversion or otherwise of that issuer. A plan of division may
designate which of the resulting corporations is the successor corporation for
the purposes of this subchapter. The successor corporation in a division shall
have sole responsibility for payments to dissenters and other liabilities under
this subchapter except as otherwise provided in the plan of division.


     "Dissenter." A shareholder or beneficial owner who is entitled to and does
assert dissenters rights under this subchapter and who has performed every act
required up to the time involved for the assertion of those rights.


     "Fair value." The fair value of shares immediately before the effectuation
of the corporate action to which the dissenter objects, taking into account all
relevant factors, but excluding any appreciation or depreciation in
anticipation of the corporate action.


     "Interest." Interest from the effective date of the corporate action until
the date of payment at such rate as is fair and equitable under all of the
circumstances, taking into account all relevant factors, including the average
rate currently paid by the corporation on its principal bank loans.


Section1573. Record and beneficial holders and owners.


       (a) Record holders of shares. A record holder of shares of a business
corporation may assert dissenters rights as to fewer than all of the shares
registered in his name only if he dissents with respect to all the shares of
the same class or series beneficially owned by any one person and discloses the
name and address of the person or persons on whose behalf he dissents. In that
event, his rights shall be determined as if the shares as to which he has
dissented and his other shares were registered in the names of different
shareholders.


       (b)  Beneficial owners of shares. A beneficial owner of shares of a
business corporation who is not the record holder may assert dissenters rights
with respect to shares held on his behalf and shall be treated as a dissenting
shareholder under the terms of this subchapter if he submits to the corporation
not later than the time of the assertion of dissenters rights a written consent
of the record holder. A beneficial owner may not dissent with respect to some
but less than all shares of the same class or series owned by the owner,
whether or not the shares so owned by him are registered in his name.


Section1574. Notice of intention to dissent.


     If the proposed corporate action is submitted to a vote at a meeting of
shareholders of a business corporation, any person who wishes to dissent and
obtain payment of the fair value of his shares must file with the corporation,
prior to the vote, a written notice of intention to demand that he be paid the
fair value for his shares if the proposed action is effectuated, must effect no
change in the beneficial ownership of his shares from the date of such filing
continuously through the effective date of the proposed action and must refrain
from voting his shares in approval of such action. A dissenter who fails in any
respect shall not acquire any right to payment of the fair value of his shares
under this subchapter. Neither a proxy nor a vote against the proposed
corporate action shall constitute the written notice required by this section.


Section1575. Notice to demand payment.


      (a) General rule. If the proposed corporate action is approved by the
required vote at a meeting of shareholders of a business corporation, the
corporation shall mail a further notice to all dissenters who gave due notice
of intention to demand payment of the fair value of their shares and who
refrained from voting in favor of the proposed action. If the proposed
corporate action is to be taken without a vote of shareholders, the corporation
shall send to all shareholders who are entitled to dissent and demand payment
of the fair value of their shares, a notice of the adoption of the plan or
other corporate action. In either case, the notice shall:


                                      D-3
<PAGE>

      (1)  State where and when a demand for payment must be sent and
           certificates for certificated shares must be deposited in order to
           obtain payment.

      (2)  Inform holders of uncertificated shares to what extent transfer of
           shares will be restricted from the time that demand for payment is
           received.

      3)   Supply a form for demanding payment that includes a request for
           certification of the date on which the shareholder, or the person on
           whose behalf the shareholder dissents, acquired beneficial ownership
           of the shares.

     (4)   Be accompanied by a copy of this subchapter.

       (b) Time for receipt of demand for payment. The time set for receipt of
the demand and deposit of certificated shares shall be not less than 30 days
from the mailing of the notice.


Section 1576. Failure to comply with notice to demand payment, etc.

       (a) Effect of failure of shareholder to act. A shareholder who fails to
timely demand payment, or fails (in the case of certificated shares) to timely
deposit certificates, as required by a notice pursuant to section 1575
(relating to notice to demand payment) shall not have any right under this
subchapter to receive payment of the fair value of his shares.

       (b) Restriction on uncertificated shares. If the shares are not
represented by certificates, the business corporation may restrict their
transfer from the time of receipt of demand for payment until effectuation of
the proposed corporate action or the release of restrictions under the terms of
section 1577(a) (relating to failure to effectuate corporate action).

       (c) Rights retained by shareholder. The dissenter shall retain all other
rights of a shareholder until those rights are modified by effectuation of the
proposed corporate action.


Section 1577. Release of restrictions or payment for shares.

       (a) Failure to effectuate corporate action. Within 60 days after the
date set for demanding payment and depositing certificates, if the business
corporation has not effectuated the proposed corporate action, it shall return
any certificates that have been deposited and release uncertificated shares
from any transfer restrictions imposed by reason of the demand for payment.

       (b) Renewal of notice to demand payment. When uncertificated shares have
been released from transfer restrictions and deposited certificates have been
returned, the corporation may at any later time send a new notice conforming to
the requirements of section 1575 (relating to notice to demand payment), with
like effect.

       (c) Payment of fair value of shares. Promptly after effectuation of the
proposed corporate action, or upon timely receipt of demand for payment if the
corporate action has already been effectuated, the corporation shall either
remit to dissenters who have made demand and (if their shares are certificated)
have deposited their certificates the amount that the corporation estimates to
be the fair value of the shares, or give written notice that no remittance
under this section will be made. The remittance or notice shall be accompanied
by:

      (1)  The closing balance sheet and statement of income of the issuer of
           the shares held or owned by the dissenter for a fiscal year ending
           not more than 16 months before the date of remittance or notice
           together with the latest available interim financial statements.

      (2)  A statement of the corporation's estimate of the fair value of the
           shares.

      (3)  A notice of the right of the dissenter to demand payment or
           supplemental payment, as the case may be, accompanied by a copy of
           this subchapter.

       (d) Failure to make payment. If the corporation does not remit the
amount of its estimate of the fair value of the shares as provided by
subsection (c), it shall return any certificates that have been deposited and
release uncertificated shares from any transfer restrictions imposed by reason
of the demand for payment. The


                                      D-4
<PAGE>

corporation may make a notation on any such certificate or on the records of
the corporation relating to any such uncertificated shares that such demand has
been made. If shares with respect to which notation has been so made shall be
transferred, each new certificate issued therefor or the records relating to
any transferred uncertificated shares shall bear a similar notation, together
with the name of the original dissenting holder or owner of such shares. A
transferee of such shares shall not acquire by such transfer any rights in the
corporation other than those that the original dissenter had after making
demand for payment of their fair value.


Section 1578. Estimate by dissenter of fair value of shares.

       (a) General rule. If the business corporation gives notice of its
estimate of the fair value of the shares, without remitting such amount, or
remits payment of its estimate of the fair value of a dissenter's shares as
permitted by section 1577(c) (relating to payment of fair value of shares) and
the dissenter believes that the amount stated or remitted is less than the fair
value of his shares, he may send to the corporation his own estimate of the
fair value of the shares, which shall be deemed a demand for payment of the
amount or the deficiency.

       (b) Effect of failure to file estimate. Where the dissenter does not
file his own estimate under subsection (a) within 30 days after the mailing by
the corporation of its remittance or notice, the dissenter shall be entitled to
no more than the amount stated in the notice or remitted to him by the
corporation.


Section 1579. Valuation proceedings generally.

      (a)  General rule. Within 60 days after the latest of:

      (1)  Effectuation of the proposed corporate action;

      (2)  Timely receipt of any demands for payment under section 1575
           (relating to notice to demand payment); or

      (3)  Timely receipt of any estimates pursuant to section 1578 (relating
           to estimate by dissenter of fair value of shares);

if any demands for payment remain unsettled, the business corporation may file
in court an application for relief requesting that the fair value of the shares
be determined by the court.

      (b) Mandatory joinder of dissenters. All dissenters, wherever residing,
whose demands have not been settled shall be made parties to the proceeding as
in an action against their shares. A copy of the application shall be served on
each such dissenter. If a dissenter is a nonresident, the copy may be served on
him in the manner provided or prescribed by or pursuant to 42 Pa.C.S. Ch. 53
(relating to bases of jurisdiction and interstate and international procedure).
 

      (c) Jurisdiction of the court. The jurisdiction of the court shall be
plenary and exclusive. The court may appoint an appraiser to receive evidence
and recommend a decision on the issue of fair value. The appraiser shall have
such power and authority as may be specified in the order of appointment or in
any amendment thereof.

      (d) Measure of recovery. Each dissenter who is made a party shall be
entitled to recover the amount by which the fair value of his shares is found
to exceed the amount, if any, previously remitted, plus interest.

      (e) Effect of corporation's failure to file application. If the
corporation fails to file an application as provided in subsection (a), any
dissenter who made a demand and who has not already settled his claim against
the corporation may do so in the name of the corporation at any time within 30
days after the expiration of the 60-day period. If a dissenter does not file an
application within the 30-day period, each dissenter entitled to file an
application shall be paid the corporation's estimate of the fair value of the
shares and no more, and may bring an action to recover any amount not
previously remitted.


Section 1580. Costs and expenses of valuation proceedings.

       (a) General rule. The costs and expenses of any proceeding under section
1579 (relating to valuation proceedings generally), including the reasonable
compensation and expenses of the appraiser appointed by the


                                      D-5
<PAGE>

court, shall be determined by the court and assessed against the business
corporation except that any part of the costs and expenses may be apportioned
and assessed as the court deems appropriate against all or some of the
dissenters who are parties and whose action in demanding supplemental payment
under section 1578 (relating to estimate by dissenter of fair value of shares)
the court finds to be dilatory, obdurate, arbitrary, vexatious or in bad faith.
 

       (b) Assessment of counsel fees and expert fees where lack of good faith
appears. Fees and expenses of counsel and of experts for the respective parties
may be assessed as the court deems appropriate against the corporation and in
favor of any or all dissenters if the corporation failed to comply
substantially with the requirements of this subchapter and may be assessed
against either the corporation or a dissenter, in favor of any other party, if
the court finds that the party against whom the fees and expenses are assessed
acted in bad faith or in a dilatory, obdurate, arbitrary or vexatious manner in
respect to the rights provided by this subchapter.

       (c) Award of fees for benefits to other dissenters. If the court finds
that the services of counsel for any dissenter were of substantial benefit to
other dissenters similarly situated and should not be assessed against the
corporation, it may award to those counsel reasonable fees to be paid out of
the amounts awarded to the dissenters who were benefitted.

                    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. provides:

       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 officer 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 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.


                                      II-1
<PAGE>

       (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 any time 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 action (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, provision of the Certificate
   of Incorporation, By-Laws, agreement, vote of shareholders 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 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 an 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;


                                      II-2
<PAGE>

          (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, judgments, 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 interests 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

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 13(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 (a)(1)(i) and (a)(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 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.
