including without limitation terms and conditions governing certificates or

       Section 1.02. Capital Stock of Summit. All shares of the capital stock of
Summit issued or issued and outstanding immediately prior to the Effective Time,
including the Common Stock, par value $.80 per share, of Summit and the rights
attached thereto ("Summit Rights") pursuant to the Rights Agreement dated as of
August 16, 1989 between Summit and First Chicago Trust Company of New York, as
Rights Agent ("Summit Rights Agreement") (references to "Summit Stock" herein
shall mean the Common Stock of Summit with Summit Rights attached thereto),
shall be unaffected by the Reorganization and shall remain issued or issued and
outstanding, as the case may be, immediately thereafter.

       Section 1.03. Terms of Conversion of Prime Capital Stock.

       (a) At the Effective Time, by virtue of the Reorganization and without
any action on the part of any shareholder of Prime:

              (1) All shares of the Common Stock, par value $1.00 per share, of
Prime ("Prime Stock") which immediately prior to the Effective Time are
beneficially owned either directly, or indirectly through a Bank, broker or
other nominee, by Summit or a subsidiary of Summit or Prime or a subsidiary of
Prime (other than Prime Stock held as a result of foreclosures or debts
previously contracted and Prime Stock held in trust, managed, custodial or other
nominee accounts or held by mutual funds for which Prime or any subsidiary of
Prime acts as investment advisor), if any, or held in the treasury of Prime, if

consideration shall be payable or paid or delivered under this Agreement in
exchange for such Prime Stock; and

                                       2
<PAGE>

              (2) Subject to Section 1.03(a)(1), outstanding shares of Prime
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
subject to the conditions of this Agreement, sufficient shares of Summit Stock
to effect the conversion contemplated by Section 1.03 and related terms of this
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.

                                       3

       Section 1.05. Exchange Agent Arrangements. Prior to the Effective Time,
Summit shall appoint Equiserve - First Chicago Trust Division, or another entity
reasonably satisfactory to Prime, as the exchange agent ("Exchange Agent")
responsible for exchanging, in connection with and upon consummation of the
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
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.

                                       4

       (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
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
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

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

location of the required disclosure or copy in the Prime Schedules which is

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

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

nonassessable and have been issued pursuant to an effective registration
statement under the Securities Act or to the best of Prime's knowledge an

oral or written or formal or informal, pursuant to which Current Equity

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).

                                       9

       (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
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;

                                       10
<PAGE>

       (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
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:

                                       13
<PAGE>

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.
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.

                                       14
<PAGE>

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

                                       15
<PAGE>

       (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
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.

                                       16

       (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.

                                       17
<PAGE>

       (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
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.

       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
investments are pledged in the ordinary course of business (including in
connection with hedging arrangements or programs or reverse repurchase
arrangements) consistent with prudent banking practice to secure obligations of
Prime or any of its subsidiaries.

                                  ARTICLE III.
                    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

shares are issued and outstanding and 1,500,000 shares of Series R Preferred
Stock are reserved for issuance as of the date hereof

<PAGE>

       (b) Summit is qualified to transact business in and is in good standing
under the laws of all jurisdictions where the failure to be so qualified 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
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;

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

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

       Section 3.07. Absence of Changes. There has not been, since September 30,
1998, any Summit Material Adverse Change and there is no matter or fact known to
Summit which may result in any such Summit Material Adverse Change in the
future.

       Section 3.08 Absence of Undisclosed Liabilities. There are no
liabilities, whether contingent or absolute, direct or indirect, or loss
contingencies (as defined in Statement of Financial Accounting Standards No. 5)
other than (a) disclosed in the Summit Financial Statements or disclosed in the
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

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
outstanding, and to the best of Summit's knowledge, the loan and lease

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

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

(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

                               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
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 Fo 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
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,

       Section 4.10. Applicable Laws. Prime and its subsidiaries will use their

its subsidiaries in connection with the Reorganization.

       Section 4.11. Agreements of Affiliated Shareholders. Prime agrees to

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

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

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,
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.

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,
any Acquisition Proposal (as defined below). "Acquisition Proposal" is hereby
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

Thompson Coburn any tax opinion certificate reasonably required by Thompson
Coburn in connection with the issuance of the Tax Opinions (as defined at
Section 6.03), 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), 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
Closing occurs if different than the Closing Date).

       Section 4.17. Directors' and Officers' Insurance. Prime and each of its
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

"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
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.

                                       36

       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
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.

       (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).

consummate the Reorganization are subject to the simultaneous satisfaction of
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;

initiated or, to the knowledge of Summit or Prime, shall be contemplated or
threatened by the SEC.

Registration Statement and at the Closing Date (and at the date the Closing
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)
except with respect to fractional share interests, holders of Prime Stock who
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
of the Prime Stock for which it is exchanged and (d) the holding period of such
Summit Stock (including any fractional share for which cash is received) will

assuming that such Prime Stock is a capital asset in the hands of the holder
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.

federal agency, and no action, suit, arbitration or proceeding before any court,

                                  ARTICLE VIII
                 CONDITIONS PRECEDENT TO THE OBLIGATION OF PRIME

with which or the occurrence of which may be waived in whole or in part by Prime
in writing in accordance with Section 10.09:

construed to limit or prohibit any business or financing activities of Summit
including by way of illustration and not limitation, the entry by Summit after

       Section 9.02. Termination Rights.

       (a) The Board of Directors of Prime or Summit may terminate this
Agreement in the event that:

              (1) the shareholders of Prime at the meeting of shareholders
contemplated by Section 4.03, called for the purpose of approving the
Reorganization, this Agreement and the transactions contemplated by this
Agreement, upon voting, shall have failed to approve the Reorganization, this
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
after written notice of the existence thereof shall have been given to the other
party (a "Material Breach") (provided that the terminating party is not then in
Material Breach of this Agreement);

              (3) Prime's investment banker is unable to deliver the opinion
required by Section 8.07 to Prime by the day which is three business days prior
to the date the Registration Statement is declared effective by the SEC; or

              (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
occurred on or before January 3, 2000.

       (b) If either party shall refuse to close on the Closing Date because all
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.

       (c) If either party shall refuse to close on the Closing Date because all
the conditions to its obligation to close set forth in Article VII or VIII shall
not have been met (other than a failure of the condition set forth at Section
7.09 or 8.09 due to the circumstances set forth in Section 9.02(a)(1) hereof or
a failure of the condition set forth at Section 8.07 due to the circumstances
set forth at Section 9.02(a)(3) hereof): (i) the parties shall conduct the
Closing as promptly as practicable after all such conditions have been
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.

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

Recommendation or its intention to make the Recommendation as represented and
warranted at Section 2.08; and
            
              (3) as provided at Section 4.20.

       (e) In the event the Summit Price is less than $32.68125 and the quotient
obtained by dividing the Summit Price by $39.375 is more than .17 less than the
quotient obtained by dividing the Determination Date Index Price (as defined at

this Agreement by giving Summit notice of such termination, referring to this
Section 9.02(e), and this Agreement shall be terminated provided Summit receives
