     The Boards of Directors of Summit Bancorp.  and NMBT Corp. have agreed upon
a merger  combining NMBT Corp. and Summit.  We cannot complete the merger unless
the shareholders of NMBT Corp.  approve it. A special meeting of shareholders of
NMBT Corp. will be held on March 7, 2000 at the Candlewood  Valley Country Club,
401 Danbury Rd., New Milford,  Connecticut at 10:00 a.m., local time, to vote on
this merger. Summit shareholders do not have to approve the merger.

     Under the terms of the merger agreement,  which was signed October 3, 1999,
NMBT Corp. will merge into Summit and Summit will be the surviving corporation.

     If the merger is completed,  the exchange ratio, or the number of shares of
Summit common stock,  together with an equal number of preferred  stock purchase
rights under Summit's  shareholder  rights plan, you will receive for each share
of NMBT Corp.  common stock you own, will be  determined  based upon the average
closing price of a share of Summit common stock for a ten-day period ending on a
date to be determined, which is expected to be between five to ten business days
prior to the  closing of the  merger.The  exchange  ratio will not be lower than
 .7024 and will not be higher than .9503,  subject to any  adjustments  for stock
splits, stock dividends or similar transactions.

     Cash will be paid instead of fractional shares.

     On January 24, 2000,  Summit common stock,  which is traded on the New York
Stock Exchange under the symbol "SUB", closed at $27.88 per share and NMBT Corp.
common  stock,  which is traded on the Nasdaq Small Cap Market under the trading
symbol  "NMBT",  closed at $24.63 per share.  If the merger is  completed,  NMBT
Corp.   common   stock  will  no  longer  be  traded  on   Nasdaq.

merger we are proposing and it includes our merger agreement as an appendix.  It
is a proxy  statement that NMBT Corp. is using to solicit proxies for use at the
NMBT Corp.  special  shareholder  meeting.  It is also a prospectus  relating to
Summit's  issuance of up to 2,948,741  shares of Summit  common  stock,  and the

exchange  ratio, or the number of shares of Summit common stock you will receive
for each share of NMBT Corp.  common stock you own,  will be  determined  by the

share of Summit common stock is traded, ending on a date to be determined, which
is expected to be between five to ten business  days prior to the closing of the
merger.  The exchange  ratio will not be lower than .7024 and will not be higher
than .9503,  subject to possible  adjustments for stock splits,  stock dividends
and similar transactions. Cash will be paid instead of fractional shares. Summit

proxy,  to  constitute  a quorum at the  special  meeting.  The  merger  will be
approved if a majority of the shares of NMBT Corp.  common stock  outstanding on
January 24, 2000 is voted for approval of the merger. If a quorum is not present
or there are not sufficient votes to approve the merger, the special meeting may
be adjourned in order to permit further  solicitation of proxies by NMBT Corp.'s
board of directors if a majority of the shares of NMBT Corp.  common stock voted
at the meeting is voted for adjournment.

     The directors and executive  officers of NMBT Corp.  have agreed in writing
to vote their shares of NMBT Corp. common stock in favor of the merger. If these
executive officers and directors exercised all presently  exercisable options to
purchase NMBT Corp.  common stock,  they would own  approximately  21.65% of the
outstanding shares of NMBT Corp. common stock.

THE MERGER (SEE PAGE 16)

     ANTICIPATED  EFFECTIVE  DATE OF THE MERGER.  (SEE PAGE 17) If the merger is
approved by NMBT  Corp.'s  stockholders  and all the  conditions  to closing are
satisfied or waived:


     o    we will file  certificates  of merger with the State of New Jersey and
          State of  Delaware  which will  specify the date and time at which the
          merger will become effective; and

     o    we currently  expect that the merger will become  effective during the
          first  calendar  quarter of 2000.  A copy of the merger  agreement  is
          attached as Appendix A to this Proxy Statement-Prospectus.


     EXCHANGE  RATIO.  (SEE PAGE 17) The number of shares of Summit common stock
that you will receive in exchange for your NMBT Corp.  common stock has not been
fixed and under the merger  agreement cannot be fixed until after the NMBT Corp.
shareholders have approved the merger agreement.

     The exchange  ratio will be determined by the "Summit  Price".  The "Summit
Price" is defined in the merger  agreement as the average of the closing  prices
of a share of  Summit  common  stock on the New York  Stock  Exchange  Composite
Transactions  List for the ten consecutive  full trading days on which one share
of Summit common stock is traded ending on the "Determination  Date". The merger
agreement provides for an automatic Determination Date seven business days prior
to a closing  date  that will be set for 45  business  days  after all  required
shareholder  and government  approvals are received and any legal  challenges to
the merger are resolved,  but also permits  Summit to select an earlier  closing
date and to designate a  "Determination  Date" in the notice of the closing date
sent to NMBT Corp. by Summit, which notice, unless otherwise agreed to by Summit
and NMBT Corp.,  is  required  to be sent at least 5 business  days prior to the
date  designated  for closing.  The  Determination  Date may not be more than 10
business days prior to the closing date. Accordingly, if Summit decides to set a
closing date earlier than the 45th business



                                       2
<PAGE>


day  after all  required  approvals  have been  received,  Summit  can  select a
Determination  Date which is between 5 to 10 business  days prior to the closing
date  selected  by Summit.  In this  event,  Summit may  consider,  among  other
factors,   the  trading   prices  of  Summit   common  stock  in  selecting  the
Determination Date. The number of shares of Summit common stock that you receive
in exchange for your NMBT Corp.  common  stock will be based upon the  following
formula:


<TABLE>

              "SUMMIT PRICE" AS OF

Less than $27.35938 .....................................................       0.9503
</TABLE>

     You will be required to vote on the merger  agreement  prior to knowing the
exchange ratio. In addition,  it is possible that by virtue of Summit's right to
select the  Determination  Date,  Summit could choose a pricing period after the
date of the NMBT Corp.  special meeting,  which includes the NMBT Corp.  special
meeting  date,  or which  includes up to 5 days prior to the NMBT Corp.  special
meeting.


     CONVERSION OF NMBT CORP. STOCK OPTIONS.  (SEE PAGE 19) In the merger,  each
outstanding  option to buy NMBT Corp.  common  stock  under NMBT  Corp.'s  stock
option plans will  automatically  be converted into an option to purchase Summit
common  stock.  The exercise  price per share and the number of shares of Summit
common stock subject to each converted  option will be determined as provided in
the merger agreement based on the exchange ratio. In addition, for 30 days after
the merger becomes effective,  holders of NMBT Corp. stock options will have the
right to receive,  instead of exercising their options,  a cash payment equal to
the difference between the exercise price of the option and the Summit Price.

     RECOMMENDATION AND REASONS OF NMBT CORP. BOARD OF DIRECTORS.  (SEE PAGES 19
AND 21) NMBT Corp.'s board of directors  unanimously  recommends that NMBT Corp.
shareholders  vote to approve the merger and the proposal to adjourn the meeting
if necessary.

     NMBT Corp.'s board of directors has concluded  that the proposed  merger is
in the best interest of NMBT Corp., its  shareholders,  employees and customers,
and the communities which NMBT serves.  The NMBT Corp. board considered a number
of important factors, some of which are listed below:

     o    the economic  condition of NMBT Corp. and its current and  prospective
          operating environment;


     o    the  economic  condition  of Summit and its  current  and  prospective
          operating environment; and


     o    the premium  offered by Summit for NMBT Corp.'s  common stock in terms
          of market price and other recognized financial ratios.

     OPINION OF NMBT  CORP.'S  FINANCIAL  ADVISOR.  (SEE PAGE 22) In deciding to
approve the merger  agreement,  NMBT Corp.'s board of directors  engaged Advest,
Inc. to act as  financial  advisor to NMBT Corp.  and to give its opinion to the
NMBT Corp.  board as to whether  the  exchange  ratio is fair,  from a financial
point of view, to the shareholders of NMBT Corp.

     Advest has delivered to the NMBT Corp.'s board opinions dated as of October
2, 1999 and as of the date of this Proxy  Statement-Prospectus  stating that, as
of these dates,  and subject to the limitations  described in the opinions,  the
exchange  ratio is  fair,  from a  financial  point  of  view,  to NMBT  Corp.'s
shareholders.  If the merger is  completed,  Advest  will be paid a fee equal to
 .80% of the total  consideration  payable by Summit in the merger for its advice
and the  fairness  opinion.  We have  attached  Advest's  opinion as of the date
hereof as Appendix B to this Proxy  Statement-Prospectus.  You should read it in
its entirety.

     DISSENTERS  RIGHTS.  (SEE PAGE 34) Under  Delaware  law,  which governs the
rights of NMBT Corp.  shareholders,  you will have the right to dissent from the
merger,  in which event you will be entitled to receive the "fair value" of your
shares of NMBT Corp.  common  stock by complying  with the  specific  dissenters
rights  procedures  under  Delaware  law  which  are  described  in  this  Proxy
Statement-Prospectus.  The dissenters  rights provisions of the Delaware General
Corporation Law are attached as Appendix D to this Proxy Statement-Prospectus.



                                       3
<PAGE>


     FEDERAL  INCOME TAX  CONSEQUENCES.  (SEE PAGE 36) In general,  you will not
recognize  any gain or loss for federal  income tax  purposes as a result of the
exchange of shares of NMBT Corp. for shares of Summit in the merger,  except for
gain or loss arising from cash received  instead of fractional  shares or if you
exercise  dissenters  rights. We have conditioned the merger on our receipt of a
legal opinion that the federal income tax treatment for NMBT Corp.  shareholders
who  exchange  their shares of NMBT Corp.  common stock for Summit  common stock
will be as we have discussed in this document.

     ACCOUNTING  TREATMENT.  (SEE PAGE 35) Summit  expects  to  account  for the
merger under the purchase  method of  accounting.  Under the purchase  method of
accounting,  the amount by which the purchase  price paid by Summit  exceeds the
fair value of the net assets  acquired  will be treated as goodwill.  Intangible
assets, including goodwill, recorded in the transaction will be amortized over a
period not to exceed 20 years.

     REGULATORY  APPROVALS.  (SEE PAGE 27) The Board of Governors of the Federal
Reserve System and the  Commissioner of Banking of the State of Connecticut must
approve the  acquisition  of NMBT Corp.  by Summit.  The Federal  Reserve  Board
approved the transaction on December 30, 1999 and the Connecticut Commisioner of
Banking approved the transaction on January 24, 2000.

     CONDITIONS  TO THE  MERGER.  (SEE  PAGE 32) The  completion  of the  merger
depends on a number of  conditions  being  satisfied  or  waived.  Some of these
conditions include:

     o    approval of the merger by NMBT Corp.'s shareholders; and


     o    approval of the merger by the regulatory  authorities mentioned in the
          preceding paragraph without burdensome demands,  and the expiration of
          any waiting period following such approval.

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

     The merger  agreement  provides that  conditions to the merger,  other than
NMBT Corp.  shareholder  approval and receipt of required regulatory  approvals,
may be waived by the company for whose benefit the condition was included.


     TERMINATION OF THE MERGER AGREEMENT.  (SEE PAGE 32) The companies may agree
to terminate  the merger  agreement at any time without  completing  the merger.
Generally,  either Summit or NMBT Corp.,  without the consent of the other,  may
terminate the merger agreement if any of the following occurs:

     o    the shareholders of NMBT Corp. do not approve the merger;


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

     o    the  merger  is not  completed  by the  later  of July  1,  2000 or 45
          business  days after the last  required  approval or resolution of any
          legal challenges to the merger, if the approval or resolution occurred
          prior to August 1, 2000.

     Generally,  the company seeking to terminate  cannot itself be in breach of
the merger agreement so as to allow the other party to terminate.

     The merger  agreement  provides  that NMBT Corp.  may  terminate the merger
agreement if the Summit Price ending on the  Determination  Date is below $26.39
and the Summit Price has declined more than 15% than the relative  change in the
stock prices of 14 selected bank holding  companies since the time the companies
agreed to merge.


     Summit  may  terminate  the  merger  agreement  if NMBT  Corp.'s  board  of
directors  fails to recommend  approval of the merger or withdraws,  modifies or
changes, or votes to withdraw,  modify or change its recommendation for approval
of the merger  agreement,  or if the cost of  environmental  matters exceeds the
threshold set forth in the merger agreement.

     OTHER  INTERESTS OF NMBT CORP.  OFFICERS AND DIRECTORS IN THE MERGER.  (SEE
PAGE 29) Some directors and executive  officers of NMBT Corp.  have interests in
the merger  that are  different  from,  or in addition  to,  your  interest as a
shareholder of NMBT Corp.  These  interests  arise from provisions in the merger
agreement,  the rights of NMBT Corp.  officers and directors  under NMBT Corp.'s
Bylaws,  and  the  rights  of some  NMBT  Corp.  officers  under  benefit  plans
maintained by NMBT Corp. and separate agreements with NMBT Corp. and Summit, and
include the following:

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

     o    options to purchase 391,000 shares of NMBT Corp.  common stock held by
          NMBT Corp.  executive officers and directors will automatically become
          options to acquire  shares of Summit  common  stock,  adjusted for the
          exchange ratio in the merger agreement;

     o    Michael  D.  Carrigan,  Jay C.  Lent  and  Peter R.  Maher,  executive
          officers of NMBT Corp.,  have  employment  agreements  with NMBT Corp.
          which provide for severance  payments  (based upon their  compensation
          through December 31, 1999) of  approximately  $610,207 to Mr.Carrigan,
          $324,894 to Mr. Lent, and $273,264 to Mr. Maher if their employment is
          terminated under specified circumstances after the merger; and

     o    Summit has agreed to appoint five  members of the NMBT Corp.  board of
          directors  to the  board of  directors  of  Summit  Bank (CT) upon the
          merger of NMBT into Summit Bank (CT).

     NMBT Corp.'s board of directors considered these interests when it approved
the merger agreement.

     DIFFERENCE IN SHAREHOLDERS'  RIGHTS. (SEE PAGE 37) The rights of NMBT Corp.
stockholders,  which are determined by Delaware corporation law and NMBT Corp.'s
Restated  Certificate  of  Incorporation  and Bylaws  differ  from the rights of
Summit  shareholders,  which are  determined by New Jersey  corporation  law and
Summit's  Restated  Certificate  of  Incorporation  and  By-Laws.  Some  of  the
differences  in  shareholders'   rights  are  due  to  differences  between  the
corporation laws of Delaware, the state of NMBT Corp.'s  incorporation,  and the
corporation  law of  New  Jersey,  the  state  of  Summit's  incorporation.  The
remaining  differences in  shareholders'  rights are due to differences  between
NMBT  Corp.'s  Restated  Certificate  of  Incorporation  and Bylaws and Summit's
Restated Certificate of Incorporation and By-Laws. Upon completion of the merger
your  rights  as a  shareholder  of  Summit  will  be  governed  by  New  Jersey
corporation law and Summit's Restated Certificate of Incorporation and By-laws.

     OPTION AGREEMENT. (SEE PAGE 26) As a condition to its offer to acquire NMBT
Corp.,  Summit required that NMBT Corp.  grant Summit a stock option that allows
Summit to buy up to 531,043  shares of NMBT Corp.'s  common stock at an exercise
price of $18.87 per share.  Summit may  exercise  this option if and when events
relating to the potential acquisition of NMBT Corp. by someone other than Summit
occur. As of the date of this document, we do not believe that any event of this
nature has occurred. The option agreement is intended to increase the likelihood
the merger will be completed and may be expected to discourage  persons who, now
or prior to completion of the merger,  may be interested in acquiring NMBT Corp.
from  considering or proposing such an  acquisition.  A copy of the stock option
agreement is attached as Appendix C to this Proxy Statement-Prospectus.

     RECENT  DEVELOPMENTS.  (SEE PAGES 50 AND 53) On  January  19,  2000  Summit
reported net income for the year ended  December  31, 1999 of $442.6  million as
compared with $465.8  million for the year ended  December 31, 1998.  Net income
per diluted share for 1999 was $2.54 as compared with $2.63 for 1998. Net income
for 1999  reflected  an  additional  provision  for loan  losses of $60  million
pretax,  or  $.20  per  diluted  share,  recorded  in the  third  quarter  and a
restructuring  charge  of  $27.9  million  pretax,  or $.10 per  diluted  share,
recorded in the fourth quarter  associated with Summit's  business  realignment.
Summit's  total assets at December 31, 1999 were $36.4  billion as compared with
$33.1 billion at December 31, 1998.

     On  January  19,  2000 NMBT  Corp.  reported  net income for the year ended
December  31, 1999 of $3.6  million as compared  with net income of $3.2 million
for the year ended  December 31, 1998. Net income per diluted share for 1999 was
$1.31 as compared with $1.15 for 1998.  NMBT's total assets at December 31, 1999
were $403.1  million as compared with $380.5  million at December 31, 1998.

     The table below  presents,  rounded to the nearest full cent, the following
prices for Summit common stock and NMBT common stock:

     o    the closing price on October 1, 1999,  which was the last full trading
          day prior to the public  announcement  of the  execution of the merger
          agreement, and

     o    the closing  price on , January 24, 2000 (the most recent  practicable
          date prior to the date of this Proxy Statement - Prospectus).

     Also set forth below for each of these dates is the pro forma equivalent in
Summit  common  stock  of a  share  of  NMBT  Corp.  common  stock  computed  by
multiplying the applicable  price of Summit common stock by an assumed  exchange
ratio that was fixed by assuming,  for purposes of the exchange  ratio  criteria
set forth in the merger  agreement,  that the date set forth in the first column
was the date on which the  exchange  ratio was  determined  and that the average
price of Summit  common  stock during the ten-day  period used to determine  the
exchange  ratio was the last sale price of Summit common stock on that date. The
pro forma  equivalents are provided for illustration  purposes only.  Neither of
the pro forma  equivalents  are  intended  to  represent  the  actual  pro forma
equivalent  that will be  applicable to the merger  because the actual  exchange
ratio in the merger will not be calculated until after the special meeting.

            0.9503 ..........................         Less than $27.35938

     The merger agreement  provides that for Summit Prices on the  Determination
Date of between  $37.01563  and  $27.35938,  the exchange  ratio would vary from
0.7024 to 0.9503 (based on the formula of $26.00  divided by the Summit  Price).
The  exchange  ratio  of  0.8077  applies  only  if  the  Summit  Price  on  the
Determination  Date is exactly  $32.19,  the  mid-point  between  $37.01563  and
$27.35938.

           CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING INFORMATION

     Each   of   us   makes    forward-looking    statements   in   this   Proxy
Statement-Prospectus,  and in our public  documents to which we refer,  that are
subject to risks and  uncertainties.  These  forward-looking  statements include
information  about  possible or assumed  future results of our operations or the
performance  of the  combined  company  after the merger and the impact of "Year
2000"  compliance  issues.  Also,  when  we use  any of  the  words  "believes,"
"expects,"  "anticipates,"  "estimates"  or  similar  expressions  we are making
forward-looking statements.

     These  forward-looking  statements  are  intended  to qualify  for the safe
harbor provided by the Private  Securities  Litigation Reform Act of 1995. While
each of us believes that its  forward-looking  statements  are  reasonable,  you
should not place undue reliance on any forward-looking  statements,  which speak
only as of the date made.  You should  understand  that the following  important
factors,   in   addition   to   those   discussed   elsewhere   in  this   Proxy
Statement-Prospectus and in our public documents to which we refer, could affect
the future results and performance of each of us and the combined company.  This
could cause  those  results to differ  materially  from those  expressed  in our
forward-looking  statements.  Factors that might cause such a difference include
the following;

     o    deposit attrition,  customer loss or revenue loss following the merger
          may be greater than expected;

     o    expected  cost  savings  from the merger may not be fully  realized or
          realized within the expected time frame;

     o    difficulties  in  integrating  our  businesses  may  be  greater  than
          expected;

     o    competition  among  depository and other  financial  institutions  may
          increase significantly;

     o    inflation and changes in the interest rate  environment may reduce our
          margins;

     o    general economic or business  conditions,  either nationally or in the
          combined company's market areas, may be less favorable than expected;

     o    adverse changes may occur in the securities markets;

     o    legislative or regulatory changes may adversely affect our business;

     o    our ability to enter new markets successfully and capitalize on growth
          opportunities may be more difficult than expected; and

     o    technological  changes,  including "Year 2000" data systems compliance
          issues,  may be more  difficult,  time  consuming or expensive than we
          expect.

                                  INTRODUCTION


      We are providing this Proxy Statement-Prospectus to shareholders of NMBT
Corp. ("NMBT") in connection with the solicitation of proxies by the board of
directors of NMBT for the special meeting of shareholders of NMBT to be held on
March 7, 2000 at the Candlewood Valley Country Club, 401 Danbury Rd., New
Milford, Connecticut at 10:00 a.m., local time, or any adjournments thereof. At
the special meeting, the shareholders of NMBT will vote upon (i) a proposal to
approve the Agreement and Plan of Merger dated October 3, 1999 between Summit
and NMBT, and (ii) a proposal to approve in advance of voting on the merger
agreement an adjournment of the special meeting in order to permit further
solicitation of proxies by NMBT if insufficient shares are present at the
special meeting to constitute a quorum or to approve the merger agreement.
Shareholders of NMBT are entitled to exercise dissenters rights with respect to
the merger agreement. See "THE MERGER -- Dissenters Rights."

      NMBT'S BOARD OF DIRECTORS HAS UNANIMOUSLY APPROVED THE MERGER AGREEMENT
AND UNANIMOUSLY RECOMMENDS THAT NMBT SHAREHOLDERS VOTE FOR ITS APPROVAL. NMBT'S
BOARD ALSO RECOMMENDS THAT NMBT SHAREHOLDERS VOTE FOR APPROVAL OF THE
ADJOURNMENT PROPOSAL.


                                 SPECIAL MEETING

RECORD DATE


     The record date for determining the NMBT  shareholders  entitled to vote on
the merger at the  special  meeting is January  24,  2000.  Only the  holders of
record  of NMBT  common  stock as of the  close  of  business  on that  date are
entitled  to vote at the  special  meeting.  Each  share  of NMBT  common  stock
entitles  the  holder  to one vote on each  proposal  and on all  other  matters
properly  brought  before  the  special  meeting.  NMBT  had no  other  class of
outstanding  voting  securities  entitled to vote on the merger agreement or the
adjournment  proposal  at the close of business  on the record  date.  As of the
record date,  there were  approximately  1,728  holders of record of NMBT common
stock and 2,699,958  shares of NMBT common stock  outstanding and eligible to be
voted at the special meeting.


QUORUM AND VOTE REQUIRED

     Generally,  in order to conduct business at a shareholders meeting a quorum
must be present. A majority of the shares of NMBT common stock entitled to vote,
whether present in person or represented by proxy,  will constitute a quorum for
the transaction of business at the special meeting.  By checking the appropriate
box on the proxy card provided by NMBT's board of directors,  you may vote "FOR"
approval  of the  merger  agreement,  vote  "AGAINST"  approval  of  the  merger
agreement or "ABSTAIN" from voting.  You have similar choices with regard to the
adjournment  proposal.  Under the Delaware General Corporation Law (the "DGCL"),
the law under which NMBT was formed, the affirmative vote of the majority of the
outstanding  shares  entitled  to vote on the merger is  required to approve the
merger agreement and the affirmative vote of a majority of the shares present in
person or represented by proxy at the special meeting is required to approve the
adjournment  proposal.  Under NMBT's Restated Certificate of Incorporation,  the
approval  of the  merger  agreement  requires  only  the  affirmative  vote of a
majority of the  outstanding  shares  entitled to vote on the merger because the
merger  agreement  has been  approved by at least  two-thirds  of the members of
NMBT's  board  of  directors.   Therefore,   the  higher  shareholder   approval
requirements for certain business  combinations  which have not been so approved
by NMBT's board of directors, or which do not satisfy other conditions set forth
in NMBT's  Restated  Certificate  of  Incorporation,  are not  applicable to the
merger.

VOTING OF PROXIES

     Shares  represented  by a proxy  will be voted at the  special  meeting  as
specified in the proxy.

     PROXIES WITHOUT VOTING  INSTRUCTIONS.  Proxies that are properly signed and
dated but which do not contain voting instructions will be voted for approval of
the merger and the adjournment proposal.  Proxies voted against the merger which
do not contain voting instructions on the adjournment proposal will abstain from
voting on the adjournment proposal.

     ABSTENTIONS. NMBT will count a properly executed proxy marked "ABSTAIN" for
purposes  of  determining  whether  there  is  a  quorum  and  for  purposes  of
determining  the  number  of  shares  represented  and  entitled  to vote at the
meeting.  Because the affirmative  vote of a majority of the shares  outstanding
and entitled to vote is required for approval of the merger and the  affirmative
vote of a majority of shares present and entitled to vote is required for

                                       9
<PAGE>

approval of the adjournment  proposal,  if you mark your proxy "ABSTAIN" it will
have the effect of a vote against  approval of the merger  agreement and against
approval of the adjournment proposal.

     BROKER NON-VOTES.  If your shares are held by your broker, your broker will
vote your shares for you only if you provide  instructions to your broker on how
to vote your shares.  You should follow the  directions  provided by your broker
regarding  how to instruct your broker to vote your shares.  In accordance  with
the rules of the New York Stock Exchange, your broker cannot vote your shares of
NMBT  common  stock  without  specific   instructions   from  you.  Because  the
affirmative vote of a majority of the shares outstanding and entitled to vote is
required to approve the merger,  if you do not instruct  your broker how to vote
it will have the effect of a vote against approval of the merger  agreement.  If
you do not  instruct  your broker how to vote it will have no effect on approval
of the adjournment proposal.

     OTHER  MATTERS.  If you sign the proxy  card,  you grant  authority  to the
holders of the proxy to vote in their  discretion  on any other matters that may
properly come before the special  meeting or any  adjournment  or  postponements
thereof.  NMBT's  management  does not presently know of any other matters to be
brought before the special  meeting.  As to other matters that may properly come
before  the  special  meeting,  unless  otherwise  provided  in NMBT's  Restated
Certificate  of  Incorporation  or  Bylaws or by  statute,  the  matter  will be
approved if a majority of the votes cast are in favor of the matter.

     If a quorum is not  present,  or if fewer  shares of NMBT common  stock are
voted in favor of approval of the merger  agreement than the number required for
approval,  NMBT  currently  expects that, if a majority of the shares voted,  in
person or by proxy, with respect to the adjournment  proposal have been voted in
favor of that proposal,  the special  meeting will be postponed or adjourned for
the purpose of allowing  additional  time for  obtaining  additional  proxies or
votes. At any subsequent  reconvening of the special meeting all proxies will be
voted in the same manner as such  proxies  would have been voted at the original
convening of the special meeting (except for any proxies which have  effectively
been revoked or withdrawn).

     HOW TO VOTE SHARES HELD THROUGH  BROKERS.  If you hold NMBT common stock in
the name of a broker or other  custodian and wish to vote those shares in person
at the special meeting, you must obtain from the nominee holding the NMBT common
stock in the nominees' name a properly executed "legal proxy" identifying you as
a NMBT  shareholder,  authorizing  you to act on  behalf of the  nominee  at the
special  meeting and  identifying the number of shares with respect to which the
authorization is granted.

HOW TO REVOKE A PROXY

     Granting  a proxy on the  enclosed  proxy  card will not  prevent  you from
voting in person at the NMBT special  meeting or otherwise  revoking your proxy.
You may revoke a proxy at any time prior to the special  meeting by delivering a
properly  signed  revocation  or a proxy  bearing a later date,  to Jay C. Lent,
Secretary of NMBT, 55 Main Street,  New Milford,  Connecticut,  06776-2400 or by
giving written notice of revocation in person at NMBT's special meeting prior to
any vote being taken or appearing in person and voting at the special meeting.

SOLICITATION OF PROXIES

     NMBT will bear the cost of soliciting  proxies. In addition to solicitation
by mail,  NMBT's  directors,  officers or  employees  may solicit  proxies  from
shareholders by telephone,  in person or by other means.  These persons will not
receive  additional  compensation,  although  they  will be  reimbursed  for the
reasonable,   out-of-pocket   expenses  they  incur  in  connection   with  this
solicitation.   NMBT  will  also  make   arrangements   with  brokerage   firms,
fiduciaries,  and  other  custodians  who  hold  shares  of  record  to  forward
solicitation  materials  to the  beneficial  owners of those  shares.  NMBT will
reimburse those brokerage  firms,  fiduciaries,  and other  custodians for their
reasonable   out-of-pocket   expenses  in  connection  with  this  solicitation.
ChaseMellon  Consulting  Services,  a proxy  soliciting firm, will assist in the
solicitation  of  proxies  for a fee of $5,500  plus fees for  direct  telephone
solicitations,  if authorized,  and  reimbursement  of reasonable  out-of-pocket
costs.  Summit will pay the  expenses  incurred  for the printing and mailing of
this Proxy Statement-Prospectus and related filing fees.

STOCK HELD BY NMBT DIRECTORS AND OTHERS


     The directors and executive officers of NMBT and certain persons who may be
deemed to be  affiliates  of NMBT  beneficially  owned,  as of January 24, 2000,
669,300  shares of NMBT common  stock,  assuming  they  exercised  all currently
exercisable options to purchase NMBT common stock. This figure represents 21.65%
of the outstanding  shares of NMBT common stock after exercise of those options.
Each of the  directors  and  executive  officers  of NMBT  has  entered  into an
agreement  with Summit to vote all of their shares of NMBT common stock in favor
of the proposal to approve the merger.


     Summit   beneficially  owns  1,000  shares  of  NMBT  common  stock,  which
represents  less than 1% of the  outstanding  shares of NMBT common  stock,  and
intends to vote these  shares in favor of the proposal to approve the merger and
the proposal to adjourn the special meeting, if necessary. In addition, NMBT has
granted Summit a stock option that allows Summit to acquire up to 531,043 shares
of NMBT common  stock.  This option is not  currently  exercisable  and the NMBT
common stock  represented by the option has not been issued and cannot currently
be voted.

            COMPARATIVE AND PRO FORMA PER SHARE FINANCIAL INFORMATION

     The per share data below shows the net income, dividends and book value per
share for Summit and NMBT on an  historical  basis and on a pro forma basis.  We
derived  the pro  forma  combined  data  by  combining  historical  consolidated
financial information of Summit and NMBT using the purchase method of accounting
for  business  combinations.  We derived the pro forma NMBT  equivalent  data by
multiplying  the Summit pro forma data by the exchange ratios assumed in the pro
forma  computation.  As previously  discussed,  the exchange  ratio has not been
fixed and will not be fixed until after the special meeting. The actual exchange
ratio may differ from the exchange ratios used in the following table.

     The pro forma  information does not reflect cost savings  anticipated to be
realized  from the merger.  The  purchase  accounting  adjustments  used for the
purpose of  calculating  the pro forma  combined  results  are  subject to final
determination,  based upon estimates and other evaluations of fair value, at the
effective time of the merger.  Therefore, the pro forma amounts reflected in the
pro forma per share financial information may differ from the amounts ultimately
determined. The unaudited pro forma information is not necessarily indicative of
the combined financial position or results of operations of future periods.

COORDINATION AND DETERMINATION OF DIVIDENDS UNDER MERGER AGREEMENT

     In order to ensure that NMBT  shareholders  are paid no more,  and no less,
than  one  regular  dividend  in each  calendar  quarter  until  the  merger  is
consummated,  NMBT has agreed to coordinate  with Summit the  declaration of any
dividends  and the setting of any dividend  record or payment  dates.  Under the
merger  agreement,  NMBT may  declare a  quarterly  dividend  equal to  Summit's
dividend rate  multiplied by 0.7024.  In addition,  if the actual exchange ratio
for the merger is greater than  0.7024,  NMBT  shareholders  will be entitled to
receive a cash payment per share of NMBT stock held at the effective time of the
merger equal to the  difference  between the dividends that would have been paid
if the higher exchange ratio had been applied and the dividends actually paid by
NMBT.

DIVIDEND LIMITATIONS

     Summit's  primary source of funds to pay dividends to its  shareholders  is
provided by dividends from its subsidiary banks.  Summit's bank subsidiaries are
restricted  by law in the  amount  of  dividends  they  may  pay to  Summit.  In
addition,  some debt agreements  restrict the amount of dividends Summit may pay
to its  shareholders.  At September  30,  1999,  Summit's  subsidiary  banks had
approximately $59.1 million available,  under the most restrictive  limitations,
for the payment of dividends to Summit.


     Similarly,  NMBT's  primary  source  of  funds  to  pay  dividends  to  its
shareholders  is provided by dividends from its bank  subsidiary  ("NMBT Bank").
NMBT  Bank is also  restricted  by law in the  amount of  dividends  that it may
declare and pay to NMBT.


                 PROPOSAL I-- APPROVAL OF THE MERGER AGREEMENT

                                   THE MERGER

     The  discussion  in this Proxy  Statement-Prospectus  of the merger and the
description of the principal  terms and  conditions of the merger  agreement and
the merger are subject to and  qualified  in their  entirety by reference to the
merger agreement.  A copy of the merger agreement is attached hereto as Appendix
A and is incorporated herein by reference.

GENERAL

     The  merger  agreement  provides  for the  acquisition  of NMBT by  Summit,
pursuant to the merger of NMBT with and into Summit or a wholly owned subsidiary
of Summit or the merger of a wholly  owned  subsidiary  of Summit  with and into
NMBT,  as  determined  by Summit.  Summit has decided to merge NMBT into Summit,
with Summit as the surviving corporation in the merger.

     Upon  consummation  of the merger,  each  outstanding  share of NMBT common
stock other than (1) shares of NMBT common stock beneficially owned by Summit or
a subsidiary of Summit,  other than shares held in a fiduciary  capacity or as a
result of foreclosures  or debts  previously  contracted,  if any, (2) shares of
NMBT common stock beneficially owned by NMBT or a subsidiary of NMBT, other than
shares of NMBT  common  stock  held in a  fiduciary  capacity  or as a result of
forfeitures  or debts  previously  contracted,  if any,  and (3)  shares of NMBT
common stock held in the treasury of NMBT,  if any,  will be converted  into and
represent  the right to receive  whole  shares of Summit  common  stock and cash
instead  of  fractional  shares  resulting  from the  conversion  based  upon an
exchange  ratio to be  determined,  adjusted if  necessary  in  accordance  with
certain  anti-dilution  provisions  described  below.  The  cash  paid  for each
fractional  share  resulting from the conversion  will be an amount equal to the
fractional  share  multiplied  by the closing  price of a share of Summit common
stock on the New York Stock  Exchange  Composite  Transactions  List on the last
trading day ending prior to the effective time of the merger. The exchange ratio
is subject to appropriate  adjustments if, from the date of the merger agreement
to the effective  time of the merger,  the  outstanding  shares of Summit common
stock are increased, decreased, changed into or exchanged for a different number
or   kind  of   shares   or   securities   through   merger,   recapitalization,
reclassification,  stock  dividend,  stock split or reverse stock split or other
similar  changes.  Except in the case of  adjustment  to prevent  dilution,  the
exchange ratio will not be lower than 0.7024 and will not be higher than 0.9503.
Summit  expects to  repurchase in the open market the number of shares of Summit
common  stock  equal to the  approximate  number  of  shares to be issued in the
merger or reissue  previously  acquired  shares held in  treasury,  depending on
market conditions or other factors.

<PAGE>

CLOSING AND EFFECTIVE TIME

     The merger  agreement  provides that,  unless Summit  designates an earlier
date and gives NMBT at least five  business days notice of the new date, we will
hold the closing of the merger 45  business  days after the last to occur of the
following (the "Scheduled Date"):

     o    if the  transactions  contemplated  by the merger  agreement are being
          contested in any legal proceedings, the date that all such proceedings
          have been brought to a conclusion favorable, in the judgment of Summit
          and NMBT, to the consummation of the transactions  contemplated by the
          merger  agreement  or any prior date as Summit  and NMBT shall  elect,
          whether or not those proceedings have been brought to a conclusion; or

     o    the date on which the approvals of NMBT's  shareholders,  the Board of
          Governors of the Federal  Reserve System and the  Connecticut  Banking
          Commissioner  have been received and any required waiting periods have
          expired.


     If NMBT shareholders approve the merger agreement by the required vote, all
other  conditions  of the merger are satisfied or waived and the closing is held
on the date set for  closing,  the merger will become  effective at the date and
time  specified  in the  certificates  of merger  required  to be filed with the
Secretary  of State of the  states of New  Jersey  and  Delaware  following  the
closing date. If NMBT shareholders approve the merger agreement on the scheduled
date of the special  meeting,  subject to the  satisfaction or waiver of certain
other  conditions  described  herein,  we presently  expect that the merger will
become  effective  during the first calendar  quarter of 2000.  Either party may
terminate  the merger  agreement  if, among other  things,  the closing fails to
occur on or before the later of July 1, 2000 or 45 business  days after the last
required  approval  or  resolution  of any  legal  challenges  to the  merger or
determination to close despite a legal challenge, if the approval, resolution or
determination occurred on or before August 1, 2000, the NMBT shareholders do not
approve  the merger  agreement  at the meeting of  shareholders  called for that
purpose or a party materially  breaches a warranty,  representation  or covenant
and does not cure the breach within 30 days;  however,  a party may not exercise
this  right if the  failure to close is due  solely to that  party's  failure to
perform or observe  agreements  required by the merger agreement to be performed
or observed by it on or before the closing date. Summit's board of directors and
NMBT's  board of  directors  each also has the  right to  terminate  the  merger
agreement under certain  circumstances.  See "THE MERGER -- The Merger Agreement
- -- Conditions to the Merger; Termination."


EXCHANGE RATIO

     In the Merger,  your shares of NMBT common stock will be converted into and
represent  the  right  to  receive  Summit  common  stock  and cash  instead  of
fractional  shares.  However,  the exchange ratio,  and the date as of which the
exchange  ratio  will be  determined,  have not been fixed and will not be fixed
until a date after the special  meeting.  Once the  Determination  Date has been
fixed, the exchange ratio will be determined as follows, based on the average of
the  closing  prices  of a share  of  Summit  common  stock as  reported  on the
NYSE-Composite  Transactions  List for the ten  consecutive  full trading day on
which a share of Summit common stock is traded, ending on the Determination Date
(the "Summit Price"):

     (1)  If the Summit Price is greater than $37.01563, the exchange ratio will
          be 0.7024.

     (2)  If the Summit Price is equal to or less than $37.01563 and equal to or
          greater  than  $27.35938,  the  exchange  ratio  will be  equal to the
          quotient obtained by dividing $26.00 by the Summit Price.

     (3)  If the Summit Price is less than $27.35938, the exchange ratio will be
          0.9503.

     The  "Determination  Date"  will be the date which is seven  business  days
prior to the 45th  business day after the receipt of all required  approvals and
the resolution of any legal  challenges to the merger or  determination to close
despite a legal  challenge  or,  alternatively,  the date  designated by Summit,
along with the  closing  date,  in the  closing  notice  sent by Summit to NMBT.
However,  the merger  agreement does not permit the closing notice to be sent to
NMBT by Summit until (i) NMBT  shareholders  have approved the merger,  (ii) all
required regulatory  approvals have been received and applicable waiting periods
have expired and (iii) any litigation contesting the merger has been resolved to
the satisfaction of Summit and NMBT or Summit and NMBT agree to close the merger
despite the existence of litigation.  Consequently,  under the merger agreement,
it is not possible for the Determination Date to be designated,  or the exchange
ratio to be fixed, prior to the approval by NMBT shareholders of the merger. You
will,

                                       17
<PAGE>

therefore,  be required to vote on the proposal to approve the merger  agreement
prior to the determination of the exchange ratio.

     The Merger  Agreement  provides  that if Summit  designates  a closing date
prior to the 45th  business day after the receipt of all required  approvals and
resolutions  of legal  challenges,  Summit must send the closing notice not less
than five business  days in advance of the Closing Date  designated by Summit in
the  closing  notice or a shorter  period as agreed to in writing  by NMBT,  and
Summit must  designate  one of the business  days in the ten business day period
immediately  preceding the closing date as the  Determination  Date.  Due to the
range of dates which could be designated by Summit as the Determination Date, it
is  possible  that  Summit  could  select a  pricing  period  (by  virtue of its
selection of a  Determination  Date) which includes the date of the NMBT special
meeting and up to five of the business days immediately before that date.

     The Exchange Ratio is also subject to appropriate  adjustments in the event
that, from the date of the merger agreement to the effective time of the merger,
the outstanding shares of Summit common stock are increased,  decreased, changed
into or exchanged for a different number or kind of shares or securities through
reorganization, recapitalization,  reclassification, stock dividend, stock split
or reverse stock split or other similar changes.

EXCHANGE OF NMBT CERTIFICATES

     Prior to the  effective  time of the  merger,  Summit  will  appoint  First
Chicago  Trust  Company of New York, a division of  Equiserve or another  entity
reasonably  satisfactory  to NMBT as the  exchange  agent  for  the  merger.  As
promptly as practicable  after the effective time, but in no event more than ten
days after the exchange  agent  receives an accurate  and  complete  list of all
holders of record of  outstanding  NMBT common stock as of the effective time of
the  merger,  Summit  will  cause  the  exchange  agent  to send  to  each  NMBT
shareholder a letter of transmittal and  instructions  for exchanging his or her
NMBT common stock  certificate(s)  for a certificate  representing the number of
whole  shares  of  Summit  common  stock  and,  if  applicable,  a check for the
fractional  share amount and any additional  dividend payment to which he or she
is entitled.

     To effect a proper surrender and exchange of NMBT stock  certificates,  you
must surrender to the exchange agent all of your NMBT stock  certificates  along
with properly  executed and  completed  letters of  transmittal.  Until you have
properly surrendered your NMBT stock certificate(s),  Summit may, at its option,
refuse  to pay to you  dividends  or other  distributions,  if any,  payable  to
holders of Summit common stock.  However,  upon proper surrender and exchange of
your NMBT  stock  certificate(s),  Summit  will pay to you the  amount,  without
interest,  of  dividends  and  other  distributions,  if any,  to which you were
entitled but were not paid. No transfer of NMBT common stock will be made on the
stock transfer books of NMBT at and after the effective time of the merger.

     The exchange agent shall have  reasonable  discretion to determine  whether
letters  of  transmittal  have  been  properly  completed  and  executed  and to
disregard  immaterial defects,  and any good faith decisions of Summit regarding
any matters as may be referred to it by the exchange  agent shall be binding and
conclusive.

     Summit  will  not  issue  stock  certificates  or  scrip  certificates  for
fractions  of shares  of Summit  common  stock and NMBT  shareholders  who would
otherwise be entitled to receive fractions of shares of Summit common stock will
have none of the rights  with  respect to any  fractions  of shares,  including,
without  limitation,  the right to  receive  dividends,  that a holder of a full
share of Summit common stock would possess in respect of a full share.  Instead,
these NMBT shareholders will receive cash for their fractions of shares.

     If a NMBT  shareholder  surrenders  more than one NMBT  stock  certificate,
Summit will issue to that NMBT  shareholder  a single  Summit stock  certificate
representing  the total number of whole  shares of Summit  common stock to which
that  owner is  entitled  pursuant  to the merger  agreement  based on the total
number of shares of NMBT common stock represented by all NMBT stock certificates
surrendered by that NMBT shareholder.

     YOU SHOULD NOT SURRENDER  YOUR NMBT STOCK  CERTIFICATES  FOR EXCHANGE UNTIL
YOU RECEIVE A LETTER OF TRANSMITTAL,  INSTRUCTIONS AND OTHER EXCHANGE  MATERIALS
FROM  THE  EXCHANGE  AGENT.   HOWEVER,  YOU  ARE  URGED  TO  NOTIFY  CHASEMELLON
SHAREHOLDER SERVICES, LLC , NMBT'S TRANSFER AGENT, NOW AT (800) 288-9541 IF YOUR
NMBT STOCK CERTIFICATES ARE LOST, STOLEN,  DESTROYED OR NOT PROPERLY REGISTERED,
IN ORDER TO BEGIN THE PROCESS OF OBTAINING REPLACEMENT NMBT STOCK CERTIFICATES.

CONVERSION OF NMBT STOCK OPTIONS

     Each stock option relating to NMBT common stock granted pursuant to the New
Milford Bank & Trust  Company 1988  Non-Statutory  Stock Option Plan and the New
Milford  Bank & Trust  Company  1994  Nonqualified  Stock  Option  Plan which is
outstanding  and  unexercised  at the  effective  time  of the  merger,  will be
converted  automatically  at the effective  time of the merger into an option to
purchase  Summit common stock.  Subject to the adjustments in exercise price per
share and number of shares and the two additional  revisions,  described  below,
each  converted  option  will  continue  to be  governed  by  the  terms  of the
applicable NMBT stock option plan and the stock option agreement by which it was
evidenced, including terms and provisions as to exercises. In each case:

     o    the number of shares of Summit  common stock  subject to the converted
          option  will be equal to the number of shares of Summit  common  stock
          which  would  have  been  issued in the  merger if the  shares of NMBT
          common  stock  subject to that  option  were  issued  and  outstanding
          immediately  prior to the  effective  time,  rounded  down to the next
          lower full share; and

     o    the exercise  price per share of Summit  common  stock  subject to the
          converted  option will be equal to the aggregate  exercise  price that
          would have been payable upon exercise in full of the NMBT stock option
          divided by the number of shares of Summit  common  stock  which may be
          acquired upon exercise of the converted option.

     o    converted  options held by any NMBT  employee  whose  employment  with
          Summit is  terminated  within  one year of the  effective  time of the
          merger,  other than a  termination  for  cause,  will  continue  to be
          exercisable  until the later of (1) the  option  exercise  termination
          date provided for in the NMBT option or (2) the first anniversary date
          of the  effective  date of the  merger;  however,  in no case  may the
          converted option be exercised after the option expiration date.

     o    for 30 days  following  the effective  time of the merger,  holders of
          converted  options  may elect to  receive a cash  payment  instead  of
          exercising  their  option.  The  cash  payment  will be  equal  to the
          difference  between the converted option exercise price and the Summit
          Price.

     After the  effective  time of the merger  and  within 45 days after  Summit
receives an accurate  and  complete  list of all holders of NMBT stock  options,
Summit will issue to each holder of  converted  options,  upon  surrender of all
agreements under which NMBT stock options were issued to the holder, appropriate
instruments confirming the conversion described above. However, Summit will have
no obligation  to issue  confirming  instruments  or any shares of Summit common
stock  issuable upon  exercise of a converted  option until the shares of Summit
common  stock  issuable  upon  exercise  of  the  converted  options  have  been
registered with the Securities and Exchange  Commission,  authorized for listing
on the New York Stock Exchange and authorized for sale by any appropriate  state
securities  regulators.  Summit  will  use its  best  efforts  to  effect  these
registrations, listings and authorizations within 45 days after NMBT delivers to
Summit the above mentioned optionholder list.

RECOMMENDATION OF NMBT BOARD

     THE MERGER  AGREEMENT  HAS BEEN  UNANIMOUSLY  APPROVED  BY NMBT'S  BOARD OF
DIRECTORS.  NMBT'S  BOARD OF DIRECTORS  BELIEVES  THAT THE MERGER IS IN THE BEST
INTERESTS OF NMBT SHAREHOLDERS. NMBT'S BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS
THAT NMBT SHAREHOLDERS VOTE "FOR" THE PROPOSAL TO APPROVE THE MERGER AGREEMENT.

BACKGROUND

     From time to time,  NMBT's board of directors,  with the assistance of NMBT
management,  its financial advisor and its legal counsel,  has evaluated various
strategic  alternatives,  including  growth by internal  expansion,  purchase of
other  financial  institutions  and  acquisition  of NMBT by  another  financial
institution. In the spring of 1999, acting upon the instructions of NMBT's board
of directors,  NMBT's  management  was again directed to consider and advise the
board on  strategic  alternatives.  As in the past,  NMBT's  financial  advisor,
Advest, Inc. ("Advest"), was engaged to assist NMBT's board and management.

     In mid July,  1999,  John R. Feeney,  Executive  Vice  President of Summit,
telephoned Michael D. Carrigan,  President and a director of NMBT, and requested
a meeting to discuss a potential business  combination  between NMBT and Summit.
After  consulting with Louis Funk, Jr.,  Chairman of the NMBT board of directors
and a director



                                       19
<PAGE>



of NMBT, Mr. Carrigan,  Mr. Funk, and Robert W.X.  Martin, a director,  met with
Mr.  Feeney and  Frederick  Afragola,  Chairman of Summit Bank (CT), on July 27,
1999.  During the meeting,  Mr. Feeney expressed  Summit's interest in acquiring
NMBT.

     Shortly  thereafter,  Messrs.  Funk and  Carrigan met  informally  with two
members of another financial institution's board of directors, who expressed the
interest of their institution to acquire NMBT.

     On August 4, 1999, a special  meeting of NMBT's board of directors was held
for the specific purpose of reviewing NMBT's  strategic  business  alternatives,
and in  particular,  of evaluating the verbal  expressions of interest  received
from Summit and the other  financial  institution.  Also  present at the meeting
were  representatives  of NMBT's  special legal  counsel,  Mintz,  Levin,  Cohn,
Ferris,  Glovsky and Popeo, P.C. ("Mintz Levin"),  and NMBT's financial advisor,
Advest.  After an extended  discussion,  NMBT's board of directors  arrived at a
consensus  that the sale of NMBT at that time may not be in the best interest of
NMBT  shareholders,  but given the current and  prospective  highly  competitive
banking  environment in the primary  markets served by NMBT and the  anticipated
change in the accounting treatment for business  combinations,  and the possible
moderating  effect of that change upon the  consideration  to be received upon a
sale  of a  financial  institution,  the  NMBT  board  of  directors  instructed
management to more fully explore the level of interest,  if any,  which selected
institutions,  including  Summit,  may have to acquire  NMBT.  The NMBT board of
directors   concluded  that  a  wider  range  of  potential  suitors  should  be
approached,   and  instructed   Advest  to  contact  two  additional   financial
institutions  which  the NMBT  board of  directors  determined  should  have the
resources and interest to acquire NMBT.  Mr.  Carrigan was instructed to contact
the financial  institution whose  representatives  had met with Messrs. Funk and
Carrigan in July.  Advest was  instructed  to directly  contact  Summit,  and to
request that its level of interest be  expressed  in writing and to  communicate
with the two other identified potential suitors.

     On August 13, 1999, and again on August 23, 1999,  Mr.  Carrigan and Jay C.
Lent, Executive Vice President and Chief Financial Officer of NMBT, met with the
chief executive officer of the other financial  institution which had previously
expressed an interest in acquiring NMBT to discuss specific elements,  including
pricing parameters, of a possible combination between such institution and NMBT.
At the same time, Advest  approached Summit and initiated  contacts with the two
other designated potential suitors.


     Advest  advised  NMBT's board of  directors,  at a special  meeting held on
September  8, 1999,  of the  expressions  of interest  received as of that date,
including initial pricing information.  Two institutions,  including Summit, had
submitted  written  expressions  of  interest,  and a third had provided an oral
expression.  The fourth institution requested an additional week to evaluate its
level of interest,  and to determine  whether it would submit an  expression  of
interest.  Advest distributed a written financial analysis of the four potential
suitors and a  comparison  of the three  proposals  received.  The NMBT board of
directors  concurred  that the  price  level  offered  by Summit  was  within an
acceptable  range and authorized  management to allow Summit to proceed with its
on-site due diligence review.  In addition,  the NMBT board of directors granted
the week  deferral  requested by the fourth  institution  and  deferred  further
communication with the other two potential suitors.


     On September  10, 1999,  Advest  received a written  expression of interest
from the fourth institution and on September 14, 1999  representatives of NMBT's
management  and  Advest,   including   Messrs.   Carrigan  and  Lent,  met  with
representatives of the fourth potential suitor.

     At its regularly scheduled meeting on September 15, 1999, the NMBT board of
directors  reviewed,  with  representatives  of  Advest,  the  initial  proposal
received from Summit and  management's  discussion  with,  and the expression of
interest of, the fourth potential  suitor.  During the next several days, Summit
performed its on-site due diligence review. Subsequently, the fourth institution
conveyed a second expression of interest, including an increased price proposal.

     On September 22, 1999,  NMBT's board of directors  held a special  meeting.
Robert Cox,  President of Summit, and Mr. Feeney made a presentation to the NMBT
directors.  Messrs.  Cox and  Feeney  defined  and  discussed  Summit's  overall
business philosophy, target markets, future plans, recent trends in the price of
its  common  stock,  status of  non-performing  assets,  anticipated  transition
procedures,   and  other  matters.   After  Messrs.  Cox  and  Feeney  departed,
representatives  of Advest  reviewed  with the NMBT board of directors  the four
proposals  received to date.  Particular  focus was placed on the  evaluation of
each potential  suitor's stock since each suitor had proposed a  stock-for-stock
transaction.



                                       20
<PAGE>

     A special  meeting of NMBT's board of directors  was held on September  27,
1999. A representative  of Advest reported that he had been advised that the due
diligence  review  conducted by Summit had proceeded  well,  and that Summit had
expressed  an  interest  to  proceed  at the per  share  price  level  initially
communicated by Summit. During the discussions, it was noted that:

     o    the Summit proposed per share price range was the highest received;

     o    the directors were impressed with Summit's long-term potential;

     o    Summit's offer, as represented by the exchange ratio formula, would be
          a  substantial  premium to the current per share market price for NMBT
          common stock; and

     o    considering  various factors,  including those mentioned above and the
          liquidity  of  Summit  stock,  Summit's  management  philosophy,   the
          prospects for NMBT on a stand-alone  basis,  Summit's  willingness  to
          grant an equivalent  dividend  during the period between  announcement
          and closing and Summit's  agreement to a reasonable  ceiling and floor
          on the exchange  ratio,  the Summit  offer  appeared to be in the best
          interests of NMBT shareholders.

     Further,  the directors  concluded that, based upon Summit's  experience in
acquiring  community  banks,  including  community banks in Connecticut,  NMBT's
customers would be well served by Summit.  The directors then discussed  certain
additional  business  issues  which they  concluded  should be  reflected in the
definitive agreement.

     On September 30, 1999, a copy of the initial draft of the definitive merger
agreement was  distributed to each director for review.  A special NMBT board of
director's  meeting was held on Saturday,  October 2, 1999.  Also present at the
meeting were  representatives  of Mintz Levin and Advest.  A  representative  of
Mintz Levin  distributed a binder  containing  recent  drafts of the  definitive
merger agreement and other ancillary acquisition documents and reviewed with the
directors,  as had been done previously,  their fiduciary  responsibilities  and
reviewed separately the definitive merger agreement, the stock option agreement,
and the affiliate  agreements,  as well as the  responsibilities of NMBT and the
NMBT board of directors with respect to certain trading and disclosure  matters.
A representative of Advest provided a written comparative analysis of the Summit
offer,  and advised  the NMBT board of  directors  that  Advest was  prepared to
render a fairness  opinion with respect to the Summit  offer.  The NMBT board of
directors  scheduled another special meeting for the evening of Sunday,  October
3, 1999,  thus providing the directors time to reflect upon the discussion  held
during the October 2, 1999, meeting.

     At the October 3, 1999, meeting, held via telephone  conference,  there was
further  discussion  regarding the terms set forth in the definitive  agreement,
after which,  the NMBT board of directors  unanimously  approved the  definitive
merger agreement and stock option agreement.

REASONS FOR THE MERGER


     NMBT.  NMBT's board of directors has approved the merger  agreement and the
transactions provided for by the merger agreement and determined that the merger
is fair to, and in the best  interests of, NMBT and its  shareholders.  The NMBT
board of directors  therefore  recommends that holders of NMBT common stock vote
to approve and adopt the merger agreement and the  transactions  contemplated by
the merger agreement.

     The NMBT board of directors believes that the merger will enable holders of
NMBT common  stock to realize  increased  value due to the  premium  over market
price per share of NMBT common  stock,  as  represented  by the  exchange  ratio
formula.  The NMBT board of directors  also  believes that the merger may enable
NMBT's  shareholders to participate in opportunities  for appreciation of Summit
common stock. See "-Background"  and "-Opinion of NMBT's Financial  Advisor." In
reaching  its  decision  to  approve  the  merger  agreement,  the NMBT board of
directors  consulted  with Mintz Levin,  regarding the legal terms of the merger
and the board's  fiduciary  obligations  in its  consideration  of the  proposed
merger, with Advest regarding the financial aspects and fairness of the proposed
merger and with management of NMBT.  Without  assigning any relative or specific
weight,  the NMBT board of directors  considered the following material factors,
many of which are  subjective  in nature,  both from a short-term  and long-term
perspective:


     (i)    the  NMBT  board of  director's  familiarity  with,  and  review  of
            Summit's business,  financial  condition,  results of operations and
            prospects,  including,  but not  limited to, its  potential  growth,
            development,   profitability   and  the  business  risks  associated
            therewith;



                                       21
<PAGE>

     (ii)   the  current and  prospective  environment  in which NMBT  operates,
            including  national  and  local  economic  conditions,   the  highly
            competitive  environment for financial institutions  generally,  the
            increased regulatory burden on financial institutions, and the trend
            toward consolidation in the financial services industry;

     (iii)  the potential for  appreciation in market value of NMBT common stock
            on both a short- and long-term  basis, as a stand-alone  entity,  in
            comparison to the exchange ratio formula;

     (iv)   information  about Summit  derived from publicly  available  data as
            well as other financial data provided by Summit and discussions with
            Summit  management  concerning the business,  financial  conditions,
            results of operations and asset quality of Summit;

     (v)    the  competitive  position  and future  growth  prospects  of Summit
            following the merger;

     (vi)   the  presentations of Advest regarding the merger and the opinion of
            Advest  that as of the  date of the  merger  agreement,  the  merger
            consideration  was  fair,  from a  financial  point of view,  to the
            holders of NMBT  common  stock (see  "-Opinion  of NMBT's  Financial
            Advisor");

     (vii)  the financial terms and other conditions of the merger agreement;

     (viii) the effect on NMBT's  employees  and market  area of the merger with
            Summit, including potential employee retention and stay bonuses; and

     (ix)   the  expectation  that  Summit  will  continue  to  provide  quality
            services  to the  communities  and  customers  served  by  NMBT  and
            Summit's  capacity,  as a larger  institution  with a larger capital
            base,  to provide a wider range of services and  enhanced  access to
            credit to such customers and communities.


     SUMMIT.  Summit's  board of  directors  believes  the merger  will  enhance
Summit's retail franchise and competitive position in key market areas.


OPINION OF NMBT'S FINANCIAL ADVISOR


     Advest  has  acted as  financial  advisor  to NMBT in  connection  with the
merger.  As part of its engagement,  Advest  delivered its written opinion dated
October 2, 1999 to NMBT's  board of  directors at the October 2, 1999 NMBT board
of directors  meeting.  Advest's opinion stated that, as of October 2, 1999, the
exchange  ratio was fair from a  financial  point of view to the holders of NMBT
common stock.  Again,  as part of its  engagement,  Advest  delivered an updated
written  opinion.  Advest's  updated  opinion states that as of the date of this
Proxy Statement-Prospectus, the exchange ratio is fair from a financial point of
view to the  holders  of NMBT  common  stock.  Except as  discussed  herein,  no
limitations  were imposed by NMBT's board of directors  upon Advest with respect
to  investigations  made or the  procedures  followed by Advest in rendering its
opinion.

     THE FULL TEXT OF THE  WRITTEN  OPINION  BY  ADVEST,  DATED THE DATE OF THIS
PROXY  STATEMENT-PROSPECTUS,  WHICH SETS  FORTH THE  ASSUMPTIONS  MADE,  MATTERS
CONSIDERED  AND  QUALIFICATIONS  AND  LIMITATIONS ON THE REVIEW  UNDERTAKEN,  IS
ATTACHED AS APPENDIX B TO THIS PROXY STATEMENT-PROSPECTUS. NMBT SHAREHOLDERS ARE
URGED TO READ THIS OPINION  CAREFULLY AND IN ITS ENTIRETY.  ADVEST'S  OPINION IS
DIRECTED ONLY TO THE FAIRNESS,  FROM A FINANCIAL  POINT OF VIEW, OF THE EXCHANGE
RATIO TO THE HOLDERS OF NMBT COMMON STOCK,  HAS BEEN PROVIDED TO NMBT'S BOARD OF
DIRECTORS IN CONNECTION WITH ITS EVALUATION OF THE MERGER,  DOES NOT ADDRESS THE
MERITS OF THE UNDERLYING  DECISION BY NMBT TO ENGAGE IN THE MERGER, AND DOES NOT
CONSTITUTE A  RECOMMENDATION  TO ANY NMBT  SHAREHOLDER AS TO HOW THE SHAREHOLDER
SHOULD  VOTE.  THE  SUMMARY  OF THE  OPINION  OF ADVEST  SET FORTH IN THIS PROXY
STATEMENT-PROSPECTUS  IS QUALIFIED IN ITS ENTIRETY BY REFERENCE TO THE FULL TEXT
OF THE OPINION.


     In arriving at its opinion, Advest among other things:

     o    Reviewed and analyzed certain publicly available financial  statements
          for NMBT and Summit and financial information made available to Advest
          by the management of NMBT and Summit;

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

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

                                       22
<PAGE>

     o    Reviewed  the stock price  performance  and  trading  activity of NMBT
          common stock and Summit common stock;

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

     o    Reviewed  and  discussed  with the  management  of NMBT and Summit the
          strategic  objectives of the merger and certain other  benefits of the
          merger;

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

     o    Reviewed  the pro forma impact of the merger and the  contribution  of
          NMBT and Summit to the new pro forma combined entity on the basis of a
          number of key financial categories in relation to pro forma ownership;

     o    Reviewed the merger agreement and the stock option agreement; and

     o    Performed  such other  analyses and  investigations  as Advest  deemed
          appropriate.


     In  rendering  its  opinion,   Advest  assumed  and  relied  upon,  without
independent verification,  the accuracy and completeness of all of the financial
and other information  reviewed by it for the purposes of providing its opinion,
and did not  assume  any  responsibility  for  independent  verification  of the
information.  Advest did not assume any responsibility for independent valuation
and appraisal of the assets and  liabilities of NMBT.  With respect to financial
projections, Advest assumed that they were reasonably prepared by the management
of NMBT on bases reflecting the best currently available estimates and judgments
of the future financial  performance of NMBT. Advest expresses no view as to the
reasonableness of the projections provided or the assumptions on which they were
based.  Advest also assumed that the merger would be  consummated  in accordance
with the terms of the merger agreement  without material waiver or modification.
Advest's  opinion dated October 2, 1999,  and its opinion dated the date of this
Proxy  Statement-Prospectus are based upon economic, market and other conditions
as they existed and could be evaluated on October 2, 1999,  and the date of this
Proxy Statement-Prospectus, respectively. The forecasts or projections furnished
to Advest  for NMBT were  prepared  by the  management  of NMBT.  As a matter of
policy,  NMBT  does  not  publicly  disclose  internal   management   forecasts,
projections or estimates of the type furnished to Advest in connection  with its
analysis of the merger,  and such forecasts,  projections and estimates were not
prepared with a view towards public disclosure. These forecasts, projections and
estimates were based on numerous  variables and assumptions which are inherently
uncertain  and which may not be within  the  control of  management,  including,
without  limitation,  general economic,  regulatory and competitive  conditions.
Accordingly,  actual results could vary  materially  from those set forth in the
forecasts,  projections  and estimates  provided by the  management of NMBT. The
following is a summary of the material analyses  conducted by Advest in updating
its  opinion  as of the date  hereof  from its  opinion  dated  October 2, 1999.
Similar  written  analyses were prepared and presented by Advest to NMBT's board
of directors at its meeting held on October 2, 1999.

     COMPARABLE  PUBLIC COMPANY  ANALYSES.  Advest reviewed  certain  financial,
operating and stock market performance data of 12 publicly traded banks and bank
holding  companies  headquartered  in the Northeast region of the United States,
each with assets  between $200 million and $900 million as of and for the twelve
months ending  September 30, 1999 (the "NMBT Peer  Companies").  Advest analyzed
the  relative  performance  and  value  of NMBT by  comparing  certain  publicly
available financial data of NMBT with that of the NMBT Peer Companies, including
ratios of tangible equity to assets, total risk based capital ratios,  return on
average assets,  return on average equity and market price to estimated earnings
per share in 1999 and market price to book value.  The  operating  data for NMBT
and the NMBT Peer  Companies  were as of or for the twelve  month  period  ended
September  30, 1999.  Stock prices for the  NMBT~Peer  Companies  were as of the
market close on January 21,  2000.  The stock price for NMBT is as of the market
close on October 1, 1999. The analyses  yielded the following  comparison of the
medians for the NMBT Peer Companies with NMBT, respectively:

     o    Tangible equity to assets ratios of 8.5% and 7.3%;

     o    Total risk based capital ratios of 14.4% and 14.4%;

     o    Return on average asset ratios of 1.2% and 1.0%;



                                       23
<PAGE>


     o    Return on average equity ratios of 13.5% and 13.1%;

     o    Market  price to  estimated  earnings  per  share in 1999 of 12.3x and
          12.1x; and

     o    Market price to book value multiples of 148% and 151%.

     Advest performed  similar analyses with respect to Summit.  Advest reviewed
and compared certain  financial,  operating and stock market performance data of
Summit with 10 publicly traded bank holding companies in the United States, each
with assets  between $25 billion and $45 billion as of and for the twelve months
ending  December 31, 1999,  except for one company whose financial and operating
data was as of September 30, 1999 (the "Summit Peer Companies"). Advest analyzed
the  relative  performance  and value of Summit by  comparing  certain  publicly
available  financial  data of Summit  with that of the  Summit  Peer  Companies,
including ratios of tangible equity to assets,  return on average assets, return
on average  equity,  market  price to earnings  per share in 1999 and  estimated
earnings per share in 2000 and market  price to book value.  The  operating  and
financial  data for  Summit  was as of and for the  twelve  month  period  ended
December 31, 1999, excluding  non-recurring  after-tax charges of $17.1 million.
All stock prices were as of the market  close on January 21, 2000.  The analyses
yielded the following  comparison  of the medians for the Summit Peer  Companies
with Summit, respectively:

     o    Tangible equity to assets ratios of 6.0% and 6.4%;

     o    Return on average asset ratios of 1.4% and 1.3%;

     o    Return on average equity ratios of 17.0% and 16.2%;

     o    Market price to earnings per share in 1999 of 11.2x and 10.7x;

     o    Market  price to  estimated  earnings  per  share in 2000 of 10.4x and
          9.3x; and

     o    Market price to book value multiples of 216% and 174%.

     COMPARABLE TRANSACTIONS ANALYSES. Advest reviewed the consideration paid or
proposed to be paid in other  transactions  in 1998,1999 and through January 21,
2000 involving banks and bank holding companies.  Specifically,  Advest analyzed
56 transactions in the Connecticut, New York, New Jersey and Pennsylvania region
involving banking companies (the "Regional  Transactions")  and 122 transactions
nationwide  with deal  values  between  $35 and $100  million  (the  "Comparable
Transactions").  In reviewing the Regional and Comparable  Transactions,  Advest
examined the multiples of price paid relative to previous twelve-month earnings,
price-to-book  value, and the thirty trading day market premium.  These analyses
yielded the following  comparison  of the medians for the Regional  Transactions
with the merger, respectively:

     o    Price to earnings for the last twelve months of 26.9 x and 21.3x;

     o    Price to book value ratios of 274% and 246%;

     o    Price to tangible book value ratios of 280% and 247%; and

     o    Price to seller common stock price before  announcement of transaction
          of 137% and 163%.

     These  analyses  yielded the  following  comparison  of the medians for the
Comparable Transactions with the merger, respectively:

     o    Price to earnings for the last twelve months of 21.9 x and 21.3x;

     o    Price to book value ratios of 286% and 246%;

     o    Price to tangible book value ratios of 301% and 247%; and

     o    Price to seller common stock price before  announcement of transaction
          of 139% and 163%.

     STOCK TRADING HISTORY.  Advest reviewed the performance of the weekly stock
prices and  trading  volume of the NMBT  common  stock  during  the period  from
December  27, 1996  through  October 1, 1999 and Summit  common stock during the
period from December 27, 1996 through January 21, 2000.  Advest compared the per
share stock price  activity of NMBT common stock to the NMBT Peer  Companies and
major bank stock  indexes and compared  the per share  market price  activity of
Summit  common stock to the Summit Peer  Companies and the same major bank stock
indexes.

     PRO FORMA  MERGER  ANALYSES.  Advest  estimated  the impact of the proposed
merger on Summit's  projected  fully  diluted  estimated  earnings per share for
2000.  Advest based its analysis on equity  analysts'  consensus  estimates  for
Summit,   conversations  it  conducted  with  the  management  of  Summit,  NMBT
management's  projected future earnings for 2000 and  conversations it conducted
with NMBT  management.  Based on this  information and the terms of the proposed
merger,   Advest   concluded  that,  for  Summit,   the  merger  could  have  an
insignificant  dilutive  effect (before taking into account various cost savings
and revenue  enhancements  which could be  accomplished  upon  consolidation  of
NMBT's and Summit's operations) on estimated fully diluted earnings per share in
2000.  Advest  also  calculated  that the  merger  could  have an  insignificant
accretive effect on Summit's  earnings per share in 2000 if pre-tax cost savings
and revenue enhancements estimated by NMBT could be achieved. Separately, Advest
also  determined  that the  merger  would  have an  accretive  effect  on NMBT's
dividend  per share of  approximately  204%,  based on Summit's  and NMBT's then
current dividend payments and Summit's January 21, 2000 market price of $28.25.

     CONTRIBUTION  ANALYSIS.  Based on Summit's January 21, 2000 market price of
$28.25,  NMBT would  receive  an  exchange  ratio of .9204  shares for each NMBT
share. NMBT's shareholders would own approximately 1.44% of the pro forma shares
outstanding,  while it would  contribute  1.10%,  1.11%,  1.22% and 1.02% of pro
forma  assets,  loans,  deposits  and equity,  respectively.  Based on analysts'
consensus  earnings estimates for Summit and internal company earnings estimates
for  NMBT,  NMBT's  earnings  contribution  in 2000  would be 0.88% of pro forma
earnings.

     DIVIDEND  DISCOUNT  ANALYSIS.  Advest  performed an analysis to calculate a
range of present  values per share of NMBT common stock  assuming NMBT continued
to operate as a stand-alone  entity.  The range was determined by adding (i) the
present value of the estimated  future  dividend stream that NMBT could generate
over the period  beginning  January 1, 2000 and ending on December 31, 2003, and
(ii) the present value of the estimated  terminal  value of NMBT common stock on
December 31, 2003. To determine a projected dividend stream,  Advest assumed (i)
an increase in assets of  approximately 8% each year for 2000 through 2003; (ii)
an increase in net income of 9% to 16% annually for 2000 through 2003; and (iii)
a dividend  payout ratio of 30% each year for 2000 through  2003.  The estimated
terminal values were based upon a range of  price-to-earnings  and price-to-book
value multiples consistent with the range of price-to-earnings and price-to-book
value multiples at which  similarly-sized  banking  institutions  located in the
United  States have traded in 1998-1999  (12 times to 16 times  previous  twelve
month  earnings per share and 1.6 times to 2.0 times book value per share) and a
range  of  discount  rates  of 12% to 15%.  Applying  the  foregoing  multiples,
discount rate and  assumptions,  Advest  determined that the fully diluted value
per share of NMBT common stock ranged from approximately  $15.70 to $22.63 based
on the price-to-earnings  multiple assumptions and $16.31 to $22.17 based on the
price-to-book value multiple assumptions.


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

     Advest's  opinion does not imply any  conclusion  as to the likely  trading
range for Summit common stock following consummation of the merger, and does not
address NMBT's underlying  business decision to effect the merger. In performing
its  analyses,  Advest  made  numerous  assumptions  with  respect  to  industry
performance,  general business,  economic,  market and financial  conditions and
other  matters,  many of which are beyond the  control of NMBT and  Summit.  Any
estimates  contained in such analyses are not  necessarily  indicative of actual
past or future


                                       25

results or values,  which may be significantly more or less than such estimates.
Actual values will depend upon several  factors,  including  changes in interest
rates, dividend rates, market conditions,  general economic conditions and other
factors that generally influence the price of securities.


     Advest is a nationally  recognized investment banking firm and was selected
by NMBT based on Advest's experience and expertise.  Advest regularly engages in
evaluation  of bank and bank  holding  company  securities  in  connection  with
acquisitions,  negotiated  underwritings,  secondary distributions of listed and
unlisted  securities,  private  placements  and  valuations  for  various  other
purposes.   In  the  ordinary   course  of  its  business,   Advest  may  effect
transactions,  for its own account or for the account of customers,  and hold at
any time a long or short position in securities of NMBT or Summit. Advest agreed
to act as financial  advisor to NMBT in  connection  with the merger.  NMBT paid
Advest  $100,000  upon  execution of the merger  agreement and $100,000 upon the
rendering of the opinion.  NMBT has also agreed to pay Advest, a transaction fee
of 0.80%  of the  aggregate  consideration  paid or  payable  by  Summit  (which
includes  Summit shares issuable or cash payable upon the exercise or retirement
of converted NMBT stock options and the dividend equivalency permitted under the
merger agreement) upon  consummation of the merger,  which will be determined as
of the closing date.  The $100,000 paid upon  execution of the merger  agreement
and the $100,000 paid upon rendering the opinion are to be credited  against the
transaction  fee of 0.80% of the  aggregate  consideration.  NMBT has  agreed to
reimburse Advest for its reasonable  out-of-pocket  expenses,  including travel,
outside  legal fees and related  charges,  and to  indemnify  Advest and related
persons against certain  liabilities,  including  certain  liabilities under the
federal  securities  laws,  from  and  arising  out of or  based  upon  Advest's
engagement on its behalf.


STOCK OPTION AGREEMENT

     As an inducement  and condition to Summit's  willingness  to enter into the
merger agreement,  NMBT entered into the NMBT Corp. Stock Option Agreement dated
as of October 4, 1999 with Summit. The following discussion  highlights selected
information  from  the  stock  option  agreement  but  may not  contain  all the
information  which is important to you. To understand the stock option agreement
fully you  should  read  carefully  the entire  document  which is  included  as
Appendix C hereto.

     Pursuant  to  the  stock  option  agreement,  NMBT  granted  to  Summit  an
irrevocable   option,   exercisable  under  limited  and  specifically   defined
circumstances,  none of which, to the best of Summit's and NMBT's knowledge, has
occurred as of the date hereof,  to purchase up to 531,043 shares of NMBT common
stock at a price of $18.87 per share.

     If Summit is in breach of any material covenant or obligation  contained in
the merger  agreement and, if the merger agreement has not been terminated prior
thereto,  that breach  would  entitle NMBT to  terminate  the merger  agreement,
Summit will not be permitted to exercise the option. Otherwise,  Summit, as long
as the option has not yet  terminated,  may exercise the option,  in whole or in
part, at any time and from time to time  following the  occurrence of a Purchase
Event, as defined below. The option will terminate upon the earliest to occur of
certain events, including:

     o    the time immediately prior to the effective time of the merger;

     o    termination  of the merger  agreement  prior to the  occurrence  of an
          Extension Event, as defined below,  other than a termination by Summit
          resulting from (1) a material  breach of the merger  agreement by NMBT
          which has not been cured or is not capable of being  cured  within the
          time  allotted,   (2)  nonsatisfaction  of  a  condition  to  Summit's
          obligation  to  close  the  merger,   other  than  failure  to  obtain
          shareholder  approval of the merger agreement or failure to obtain the
          fairness  opinion  of  Advest,  or (3) the NMBT  board  of  directors'
          failure to recommend,  or its withdrawal of or  modification or change
          to, or its vote to withdraw,  modify or change,  its recommendation to
          NMBT shareholders to approve the merger agreement; or

     o    12 months after the termination of the merger agreement  following the
          occurrence of an Extension Event, as defined below, or the termination
          of the merger  agreement by Summit upon (1) a material  breach by NMBT
          which has not been cured or is not capable of being  cured  within the
          time  allotted,   (2)  nonsatisfaction  of  a  condition  to  Summit's
          obligation  to close the  merger,  other than  failure to obtain  NMBT
          shareholder  approval of the merger agreement or failure to obtain the
          fairness opinion of Advest, or (3) the NMBT board of direc-
          tors'  failure to recommend,  or its  withdrawal  or  modification  or
          change  to,  or  its  vote  to   withdraw,   modify  or  change,   its
          recommendation to NMBT shareholders to approve the merger agreement or
          option agreement.


                                       26

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

     o    NMBT, NMBT's board of directors or any of NMBT's  subsidiaries  taking
          some   actions   (each  an   "Acquisition   Transaction"),   including
          recommending  to  shareholders  the approval  of, or entering  into an
          agreement with any third party to effect, (1) a merger,  consolidation
          or  similar   transaction   involving  NMBT  or  any  of  its  banking
          subsidiaries,  (2) the purchase,  lease,  or other  acquisition of ten
          percent or more of the  aggregate  value of the assets or  deposits of
          NMBT or any of its  banking  subsidiaries,  (3) the  purchase or other
          acquisition  of  securities  representing  ten  percent or more of the
          voting  power of NMBT or any of its  banking  subsidiaries  or (4) any
          substantially  similar  transaction,  in each case except as otherwise
          permitted by the merger agreement or option agreement;

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

     o    any  third  party's  making  a  bona  fide  proposal  to  NMBT  or its
          shareholders,  by public announcement or written communication that is
          or  becomes   publicly   disclosed,   to  engage  in  an   Acquisition
          Transaction,  including the commencement of a tender offer or exchange
          offer to purchase ten percent or more of the aggregate voting power of
          NMBT or any of its banking subsidiaries;

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

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

     o    the failure of the NMBT board of  directors  to call a meeting of NMBT
          shareholders to approve the merger  agreement,  or the failure to hold
          or  cancellation  of a  shareholders  meeting,  or the  NMBT  board of
          directors   withdrawal  or  adverse   modification  of  its  unanimous
          recommendation  of  the  merger  or a  prospective  announcement  of a
          withdrawal  or  modification  of its unanimous  recommendation.  o any
          Purchase Event, as defined below, other than that described in the 2nd
          bullet below.

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

     o    any person's,  other than Summit or a subsidiary of Summit,  acquiring
          beneficial  ownership  of 25 percent or more of the  aggregate  voting
          power of NMBT or any of its banking subsidiaries,  except as otherwise
          permitted by the merger agreement or option agreement;

     o    the NMBT  shareholders  do not approve the merger at the  shareholders
          meeting or NMBT's  board of  directors  does not call a  shareholder's
          meeting for consideration of the merger or a shareholder's  meeting is
          not held or is canceled or if NMBT's board of  directors  withdraws or
          modifies  in a manner  adverse to the  consummation  of the merger its
          recommendation of the merger or has made an advance  announcement of a
          withdrawal  or  modification,  in each case after an  Extension  Event
          other than the  Extension  Event  described in the next to last bullet
          under the definition of Extension Event above; or

     o    the  occurrence  of an Extension  Event  described in the first bullet
          under the  definition  of  "Extension  Event"  above,  except that the
          percentage  referred  to in clauses  (2) and (3)  thereof  shall be 25
          percent.

     Upon the  occurrence  of  certain  events  set  forth in the  stock  option
agreement,  at the election of Summit,  the option, or shares issued pursuant to
the  exercise  thereof,  must  be  repurchased  by NMBT or  converted  into,  or
exchanged for, an option of another corporation or NMBT. In addition,  the stock
option  agreement grants certain  registration  rights to Summit with respect to
the shares represented by the option. The terms of these repurchase,  substitute
option and registration rights are set forth in the stock option agreement.

     The stock  option  agreement  and  option  are  intended  to  increase  the
likelihood that the merger will be consummated  according to the terms set forth
in the  merger  agreement  and may be  expected  to  discourage  offers by third
parties to acquire  NMBT prior to the  merger.  To the  knowledge  of Summit and
NMBT,  no event  giving rise to the right to exercise the option has occurred as
of the date of this Proxy Statement-Prospectus.

REGULATORY APPROVALS


     The merger is subject to approval by the  Federal  Reserve  Board under the
Bank  Holding  Company  Act of 1956,  as amended  (the "BHC  Act").  The BHC Act
provides that the Federal Reserve Board may not approve any transaction (1) that
would result in a monopoly,  or that would be in furtherance of any  combination
or conspiracy to monopolize or to attempt to monopolize  the business of banking
in any part of the United  States,  or (2) the effect of which in any section of
the country may be substantially to lessen  competition,  or to tend to create a
monopoly, or that in any other manner would be in restraint of trade, unless the
Federal  Reserve Board finds that the  anti-competitive  effects of the proposed
transaction are clearly outweighed in the public interest by the probable effect
of the transaction in meeting the convenience and needs of the communities to be
served.  In conducting its review of any application  for approval,  the Federal
Reserve Board is required to consider the financial and managerial resources and
future  prospects of the company or companies and the banks  concerned,  and the
convenience  and needs of the  communities  to be served.  Under the BHC Act, as
interpreted  by the Federal  Reserve Board and the courts,  the Federal  Reserve
Board may deny any application if it determines that the financial or managerial
resources of the acquiring bank holding company are inadequate.  The acquisition
by  Summit  of 5% or  more  of  NMBT's  voting  stock  is  subject  to the  same
requirement  for approval.  Summit filed an application  for the merger with the
Federal  Reserve  Board on  November  22,  1999 and the  Federal  Reserve  Board
approved the merger on December 30, 1999.


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


     The acquisition of NMBT by Summit and NMBT Bank by Summit Bank (CT) is also
subject to the approval by the  Connecticut  Commissioner  of Banking  under the
Banking  Law  of  Connecticut  (the  "BLC").  Under  the  BLC,  the  Connecticut
Commissioner of Banking, in considering such acquisition, is to consider whether
the  acquisition  is reasonably  expected to produce  benefits to the public and
whether such benefits clearly outweigh possible adverse effects,  including, but
not limited to, an undue  concentration  of  resources  and  decreased or unfair
competition.  The  Connecticut  Commissioner  of  Banking  may not  approve  the
acquisition without considering whether: (i) the investment and lending policies
of NMBT Bank and Summit Bank (CT) prior to the merger and Summit Bank (CT) after
the merger will be  consistent  with safe and sound  banking  practices and will
benefit the state;  (ii) the  services or proposed  services of Summit Bank (CT)
after the merger will be consistent  with safe and sound  banking  practices and
will  benefit the economy of the state;  (iii) the  acquisition  of NMBT Bank by
Summit  Bank (CT)  will not  substantially  lessen  competition  in the  banking
industry  in the  state  and (iv)  Summit  Bank  (CT)and  NMBT  Bank  will  have
sufficient  capital to ensure and will  ensure that Summit Bank (CT) will comply
with applicable minimum capital requirements and will have sufficient managerial
resources to operate  Summit Bank (CT) in a safe and sound manner.  In addition,
the Connecticut  Commissioner of Banking may not approve the acquisition of NMBT
Bank by Summit  Bank (CT) (and  indirectly  by Summit)  unless the  Commissioner
finds that Summit Bank (CT) and NMBT Bank have a record of  compliance  with the
Community  Reinvestment Act of 1977 and Connecticut  community  reinvestment and
consumer protection banking laws and that following the acquisition of NMBT Bank
by Summit Bank (CT) (and indirectly by Summit),  NMBT Bank will provide adequate
services to meet the banking  needs of all  community  residents,  including low
income residents and moderate income  residents.  An application for approval of
the  acquisition  of NMBT  and  NMBT  Bank  by  Summit  and  Summit  Bank  (CT),
respectively, was filed with the Connecticut Commissioner of Banking on November
22, 1999 and was approved on January 24, 2000.

     The merger of NMBT Bank with Summit Bank (CT) after the initial acquisition
of NMBT by Summit also requires the prior approval of the FDIC under the federal
Bank Merger Act (the "BMA"). The BMA applies competitive, financial, managerial,
community  reinvestment and public service  standards similar to those described
above  with  respect  to the BHC Act.  Summit  Bank (CT) and NMBT Bank  filed an
application  with the FDIC on November 22, 1999 and on January 6, 2000, the FDIC
approved the merger of NMBT Bank with Summit Bank (CT).




                                       28
<PAGE>

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

INTERESTS OF CERTAIN PERSONS IN THE MERGER

     Directors  and  executive  officers of NMBT have  certain  interests in the
merger  that are  different  from and in  addition  to their  interests  as NMBT
shareholders. These interests are described in more detail below.

INDEMNIFICATION

     In the merger  agreement,  Summit has  agreed to  indemnify  and to advance
expenses in matters that may be subject to indemnification to persons who served
as  directors  and officers of NMBT or any  subsidiary  of NMBT on or before the
effective time of the merger with respect to liabilities and claims, and related
expenses  including  fees  and  disbursements  of  counsel,  made  against  them
resulting  from their  service as directors or officers  prior to the  effective
time  of the  merger.  Summit  further  agreed  that  this  indemnification  and
advancement  of  expenses  would be made in  accordance  with and subject to the
requirements   and  other  provisions  of  Summit's   Restated   Certificate  of
Incorporation  and By-Laws and NMBT's Restated  Certificate of Incorporation and
Bylaws  or the  certificate  of  incorporation  and  bylaws  of  the  applicable
subsidiary  of NMBT,  as in effect on the date the  parties  signed  the  merger
agreement and to the extent permitted by law.

     In the  merger  agreement,  Summit  also  agreed  that,  subject  to NMBT's
covenant  to take  all  action  necessary  to  preserve  its  rights  under  its
directors' and officers'  liability  insurance  policies with respect to matters
occurring  prior to the effective time of the merger,  for a period of six years
after the  effective  time of the merger,  Summit  would use its best efforts to
provide,  to the  persons  who served as  directors  or  officers of NMBT or any
subsidiary  of NMBT on or before the  effective  time of the  merger,  insurance
against liabilities and claims, and related expenses made against them resulting
from their  service prior to the effective  time of the merger.  This  insurance
would be  comparable in coverage to that provided by Summit to its own directors
and  officers,  but, if not  available on  commercially  reasonable  terms,  the
coverage  would  be  substantially  similar  in  all  material  respects  to the
insurance coverage provided to these individuals in these capacities on the date
of the merger agreement.  However, in no event is Summit required to expend more
than 200% of the current amount expended by NMBT on an annual basis prior to the
execution of the merger  agreement to maintain that coverage.  Summit has agreed
to use its best efforts to obtain as much  comparable  insurance as is available
for the  coverage  amount  if it is  unable to  maintain  or  obtain  comparable
coverage.  NMBT must renew any existing  insurance  or purchase  any  "discovery
period" insurance provided for under existing insurance at Summit's request.

BOARD OF DIRECTORS AND OFFICERS OF SUMMIT AND SUMMIT BANK (CONNECTICUT)

     The members of the Summit board of directors and the executive  officers of
Summit immediately prior to the effective time of the merger will continue to be
the members of the Summit board of directors and executive officers of Summit at
the effective time of the merger.

     Summit has agreed  that upon the merger of NMBT Bank with Summit Bank (CT),
Summit will cause to be elected to the board of directors of the surviving  bank
five persons who are then existing members of the NMBT board of directors.

EMPLOYMENT AGREEMENTS

     NMBT has employment agreements with Messrs. Carrigan, Lent and Maher. Their
annual salary for the period ending December 31, 1999 is $170,000,  $133,900 and
$113,900, respectively. The employment agreements provide for a term of one year
expiring  December 31, 1996,  1999 and 1999,  respectively.  The agreements also
provide for one-year  extensions  unless terminated in accordance with the terms
contained  therein.  Any increases in salary paid during  extension  periods are
determined at the discretion of the NMBT board of directors.

                                       29
<PAGE>


     Mr. Carrigan's  agreement  provides for the payment of cash severance equal
to  three  times  his  average  annual  gross  income  (excluding  stock  option
exercises)  for the previous  five years,  less one dollar,  upon his  voluntary
termination  for "good  reason" (as  defined in the  agreement)  or  involuntary
termination  other than for "cause" (as defined in the agreement)  within twelve
months  following  a "change  of  control"  (as  defined in the  agreement).  If
employment is terminated for cause or if Mr. Carrigan voluntarily terminates his
employment other than in connection with a change in control, Mr. Carrigan would
be entitled to receive compensation only through the date of termination. If his
employment is terminated for any reason other than for cause, disability,  death
or a change in  control,  then Mr.  Carrigan  would be  entitled  to be paid the
greater of (i) his salary for the months  remaining  in the term (as  defined in
the agreement) of employment, (ii) an amount equal to his current monthly salary
multiplied by the number of years (not to exceed twelve) of his  employment,  or
(iii) his salary for six months.


     The agreements for Messrs. Lent and Maher, while  substantially  similar in
form to Mr.  Carrigan's,  provide for the payment of cash severance equal to two
times their average annual gross income  (excluding stock option  exercises) for
the previous five years, less one dollar,  upon their voluntary  termination for
good reason (as defined in the  agreement)  or  involuntary  termination  within
twelve months following a "change of control" (as defined in the agreement).


     The  merger  will  constitute  a  "change  of  control"  under  each of the
above-mentioned  agreements.  If Messrs. Carrigan, Lent or Maher were to receive
payments under their agreements with NMBT based upon their compensation  through
December 31, 1999,  the estimated  amounts of the payments  would be $610,207 to
Mr. Carrigan; $324,894 to Mr. Lent and $273,264 to Mr. Maher.


     Summit has  agreed to assume  NMBT's  obligations  under  these  employment
agreements and to pay the severance  amounts provided for in the agreements upon
the earlier of a termination of the  executive's  employment  with Summit or the
first  anniversary  of the  effective  time of the merger if the  executive  has
remained employed by Summit through that time, subject to the condition that the
executive  has remained  employed by Summit at Summit's  request for up to three
months  following  the merger of NMBT Bank with  Summit  Bank (CT) and  assisted
Summit in the consolidation of the two banks.

NMBT STOCK OPTION PLANS

     As described  under "THE MERGER -- Conversion of NMBT Stock  Options," NMBT
stock  options  outstanding  at  the  effective  time  of  the  merger  will  be
automatically  converted into Summit stock options,  subject to the terms of the
NMBT option plan and grant agreement governing the NMBT stock options, including
terms and  provisions  governing  exercises.  The number of shares  covered by a
converted  option will be set by multiplying the number of shares covered by the
NMBT option by the exchange  ratio.  The  exercise  price per share of converted
option  will be equal to the  aggregate  exercise  price  that  would  have been
payable upon exercise in full of the NMBT option divided by the number of shares
of Summit  that may be  acquired  upon  exercise  of the  converted  option.

     In addition,  the merger agreement provides for two additional revisions to
NMBT options:

     o    converted  options  held by an NMBT  employee  whose  employment  with
          Summit is  terminated  within  one year of the  effective  time of the
          merger,  other than for cause,  will continue to be exercisable  until
          the later of (1) the option exercise  termination date provided for in
          the NMBT  option or (2) the first  anniversary  date of the  effective
          date of the merger;  however,  in no case may the converted  option be
          exercised after the option expiration date;

     o    for 30 days  following  the effective  time of the merger,  holders of
          converted  options  may elect to  receive a cash  payment  instead  of
          exercising  their  option.  The  cash  payment  will be  equal  to the
          difference  between the converted option exercise price and the Summit
          Price.

     The following table sets forth certain information relating to NMBT options
held by Michael D. Carrigan,  Jay C. Lent and Peter R. Maher,  and all directors
and executive officers of NMBT as a group as follows:

     o    the number of NMBT options held by such persons;


     o    the weighted average exercise price for NMBT options;

     o    the aggregate net unrealized value of NMBT options based on the number
          of shares of Summit  common stock  covered by, and the exercise  price
          of, the Summit options into which the NMBT options are convertible and
          using the last sale price of a share of Summit common stock on January
          24,  2000  of  $27.88  as  the  market   price  for  purposes  of  the
          calculation.

STAY BONUSES

     The merger agreement permits NMBT, after the closing date of the merger, to
pay "stay  bonuses" of up to  $175,000 in the  aggregate  to  employees  of NMBT
designated  by  NMBT,  after  consultation  with  Summit,  who  ~continue  to be
employees  of NMBT on such  payment  date and who  execute a  release  of claims
against Summit and its affiliates.

INCENTIVE PLAN PAYMENTS

     The merger  agreement  authorizes NMBT to pay NMBT employees up to $242,000
in bonus  compensation for services  rendered in 1999, in accordance with NMBT's
customary practice.

SEVERANCE PAY PROVISION

     Under the merger agreement,  the NMBT severance plan shall remain in effect
following the merger. The NMBT plan generally provides for eligible employees to
receive a payment equal to two weeks base pay multiplied by the employee's years
of service, up to a maximum of 20 weeks base pay.

THE MERGER AGREEMENT

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

AMENDMENT

     NMBT and  Summit  may  jointly  amend  the  merger  agreement  at any time.
However,  after the special  meeting,  no  amendment  may reduce the amount,  or
change the form, of consideration to be received by NMBT shareholders unless the
modification is submitted to a vote of NMBT shareholders.

NMBT COVENANTS

     Pursuant  to the merger  agreement,  NMBT has agreed,  among other  things,
that,  until the  effective  time of the  merger or  termination  of the  merger
agreement,  NMBT will advise  Summit of any  material  adverse  change in NMBT's
business and of certain  other  circumstances,  and the business of NMBT and its
subsidiaries will be carried on substantially in the same manner as prior to the
execution of the merger agreement.  Furthermore, until the effective time of the
merger or termination of the merger agreement, without the prior written consent
of Summit, NMBT will not declare or pay any dividend other than a quarterly cash
dividend at a rate equal to the then existing Summit dividend rate multiplied by
0.7024,  and will  refrain  from taking some other  actions,  including  certain
actions relating to changes in its capital stock, the incurrence of liabilities,
the making of certain  expenditures,  the  relinquishment of certain rights, the
amendment  of its  Restated  Certificate  of  Incorporation  and  Bylaws and the
issuance of capital stock.

      In order to ensure that NMBT shareholders would be paid no more than one
dividend in each calendar quarter between the date of the merger agreement and
the effective time of the merger, NMBT agreed in the merger agree-



                                       31
<PAGE>

ment to coordinate  with Summit the declaration of any dividends and the setting
of any dividend record or payment dates.

     NMBT also has agreed that, until termination of the merger agreement or the
effective time of the merger,  neither NMBT nor any of its  subsidiaries nor any
of the officers or directors of NMBT or its  subsidiaries  shall, and NMBT shall
direct and use its best efforts to cause its employees,  agents,  affiliates and
representatives  (including investment bankers, brokers, financial or investment
advisors,  attorneys or accountants retained by NMBT or any of its subsidiaries)
not to, initiate,  solicit or encourage,  directly or indirectly, any inquiries,
proposals  or  offers  with  respect  to,  or  engage  in  any  negotiations  or
discussions  with any person or provide any non-public  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".  The merger agreement defines "Acquisition Proposal" as
any offer, including an exchange offer or tender offer, or proposal concerning a
merger,  consolidation,  business combination or takeover transaction  involving
NMBT or any of its  subsidiaries,  or the  acquisition of any assets (other than
those permitted under the merger  agreement) or any securities of NMBT or any of
its  subsidiaries.  The  NMBT  board of  directors  may  furnish  or cause to be
furnished  non-public   information  directly  or  through  its  representatives
concerning an Acquisition Proposal if the NMBT board of directors,  after having
consulted  with  outside  counsel  and been  advised  of its legal  rights,  has
determined  that the failure to provide the non-public  information  would cause
the members of the board of  directors to breach  their  fiduciary  duties under
applicable  laws,  and,  provided  further,  that  NMBT  shall  first  obtain  a
confidentiality  agreement  in  customary  form  and  containing  at  least  the
confidentiality  provisions  set forth in the merger  agreement.  Further,  NMBT
agreed to immediately  cease any activities,  discussions,  or negotiations with
any parties conducted prior to execution of the merger agreement with respect to
an  Acquisition  Proposal.  In addition,  NMBT has agreed to notify  Summit,  by
telephone call to its chief executive officer or general counsel,  promptly upon
receipt of any  communication  with  respect  to an  Acquisition  Proposal  with
another person or receipt of a request for information  from any governmental or
regulatory  authority  with respect to a proposed  acquisition of NMBT or any of
its  subsidiaries  or assets by another party and to deliver as soon as possible
by facsimile transmission to that Summit officer a copy of any document relating
thereto promptly after any such document is received by NMBT.

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

SUMMIT COVENANTS

     Pursuant to the merger  agreement,  Summit has agreed,  among other things,
that,  until the  effective  time of the  merger or  termination  of the  merger
agreement,  Summit will advise NMBT of any material  adverse  change in Summit's
business and certain other circumstances.

CONDITIONS TO THE MERGER; TERMINATION

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

     o    Approval  of  the  merger  agreement  by  the  requisite  vote  of the
          shareholders of NMBT;

     o    Receipt  of all  required  regulatory  approvals  by  Summit  and NMBT
          without  restrictions or limitations,  that, in the reasonable opinion
          of Summit,  would materially  adversely affect the financial condition
          of Summit following the consummation of the merger, and the expiration
          of any waiting periods required by such approvals;

     o    Continued  effectiveness  of the  registration  statement  on Form S-4
          filed by Summit with the  Securities  and Exchange  Commission for the
          purpose of  registering  the shares of Summit common stock that Summit
          will issue in the merger;



                                       32
<PAGE>

     o    The receipt by Summit and NMBT of an opinion from  Thompson  Coburn as
          to certain federal income tax consequences of the merger;

     o    The New York  Stock  Exchange's  indication  that the shares of Summit
          common stock to be issued in the merger will be listed on the New York
          Stock Exchange, subject to official notice of issuance;

     o    The absence of material litigation;

     o    The absence of regulatory agreements relating to the parties;

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

     o    Other customary conditions described in the merger agreement.

     Any of these  conditions  may be waived by the party for whose  benefit the
condition was included.  However, the merger will not be consummated without the
receipt of the requisite shareholder and regulatory approvals.  Either party may
terminate the merger agreement if:

     o    NMBT  shareholders,  in a vote on the merger  agreement at the special
          meeting, fail to approve the merger agreement by the required vote;

     o    The other  party  materially  breaches a warranty,  representation  or
          covenant  and that  breach is not  ~cured or  capable  of being  cured
          within 30 days of the giving of written notice thereof,  provided that
          the terminating party is not in material breach of any representation,
          warranty, covenant or other agreement;

     o    On the  designated  closing  date of the  merger  all  the  conditions
          precedent to one party's  obligations  to close are not met due to the
          other party's material breach; or

     o    The merger  closing is not  consummated  on or before the later of (1)
          July 1,  2000;  provided,  however,  that a party  does  not  have the
          termination  right described by this clause if the failure to close by
          July 1, 2000 is due to its material breach or its failure to fulfill a
          condition to the  completion of the merger,  or, (2) the 45th business
          day after the last to occur of NMBT shareholder  approval,  receipt of
          all  required   regulatory   approvals  or  resolution  of  any  legal
          challenges  to the  merger or a  determination  by Summit  and NMBT to
          proceed  regardless  of whether the  proceeding  has been brought to a
          conclusion  (the  "Scheduled  Date"),  if the last required  event for
          setting the  Scheduled  Date has occurred on or before August 1, 2000.

     In addition,  the parties may terminate the merger agreement at any time by
mutual agreement. Summit's board of directors may terminate the merger agreement
if NMBT's board of directors modifies its recommendation of the merger agreement
or withdraws its recommendation, or if the cost of taking necessary remedial and
other  corrective  actions and measures  associated  with certain  environmental
matters exceeds $1,000,000 in the aggregate, or that cost is unascertainable but
cannot be reasonably estimated to be less than $1,000,000.

     The merger agreement  provides that NMBT's board of directors may terminate
the merger agreement if both of the following circumstances exist:

     o    The average of the closing  prices of Summit  common  stock on the New
          York  Stock  Exchange   Composite   Transactions   List  for  the  ten
          consecutive  full trading days ending on the  Determination  Date,  as
          defined below, (the "Summit Price") is less than $26.39, and

     o    The amount  obtained by dividing  the Summit Price by $32.1875 is more
          than 15% less than the amount  obtained by dividing the  Determination
          Date Index Price by the Starting  Date Index Price,  as such terms are
          defined below.

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

     o    "Determination Date" means the date which is seven business days prior
          to the  Scheduled  Date or an earlier  date which is not more than ten
          days before the closing date and is specifically  designated by Summit
          in the closing notice as the Determination Date.

     o    "Index Group" means 14 bank holding companies designated in the merger
          agreement,  the common stocks of all of which must be publicly  traded
          and as to which  there has not been  made,  since  October 1, 1999 and
          prior

                                       33
<PAGE>

          to the  Determination  Date, a public  announcement  of a proposal for
          such  company to be  acquired or for such  company to acquire  another
          company or companies in transactions with a value exceeding 25% of the
          acquiror's market capitalization.  Any such company or companies which
          does not satisfy any of the  foregoing  requirements  shall be removed
          from the Index Group.  Appropriate adjustments shall be made for stock
          splits,  stock  dividends or similar  transactions  occurring  between
          October 1, 1999 and the Determination Date.

     o    "Determination  Date Index  Price"  means the  average of the  closing
          prices of the common stock of the companies comprising the Index Group
          on the New York Stock Exchange Composite Transactions List for the ten
          consecutive full trading days ending on the Determination Date.

     o    "Starting Date Index Price" means the average of the closing prices of
          the common stock of the  companies  comprising  the Index Group on the
          New York  Stock  Exchange  Composite  Transactions  List on October 1,
          1999.

     The "Determination Date" will not occur until after the special meeting and
you will therefore not know until after that time whether this termination right
was exercisable or exercised.

EXPENSES

     If (1) either party terminates the merger agreement because the other party
has materially  breached a warranty,  representation  or covenant or because the
other  party has not met its  conditions  of closing,  or (2) Summit  terminates
because  NMBT's board of directors  modifies  its  recommendation  of the merger
agreement  or withdraws  its  recommendation,  or votes to  withdraw,  modify or
change  its  recommendation  or its  intention  to make the  recommendation,  or
because of the environmental contingency referred to above, then the terminating
party shall be reimbursed by the defaulting  party for the  terminating  party's
out-of-pocket  expenses  reasonably  incurred  in  connection  with  the  merger
agreement,  including counsel fees, printing fees and filing fees, but excluding
any brokers',  finders' or investment  bankers' fees. If the merger agreement is
terminated  by either  party  other than under  circumstances  described  in the
immediately  preceding sentence,  each party is mutually released and discharged
from liability to the other party or to any third party thereunder, and no party
is liable to any other  party for any costs or expenses  incurred in  connection
with the merger agreement, except that each party is responsible for one-half of
the  expenses   incurred  in   connection   with  the  printing  of  this  Proxy
Statement-Prospectus and the Registration Statement and the filing fees with the
Securities and Exchange  Commission,  the Federal Reserve Board, the Connecticut
Department of Banking and the New York Stock Exchange.  Each party has agreed to
indemnify the other for claims for brokerage commissions and finders' fees.

DISSENTERS' RIGHTS


     Under  Section  262 of  the  DGCL,  if you  exercise  appraisal  rights  in
connection  with the merger,  your shares of NMBT will not be converted into the
right to receive  shares of Summit  common  stock but instead  will be converted
into the right to receive  the "fair  value" of your NMBT  shares as  determined
under the DGCL.

     The following is a summary of the material provisions of section 262 of the
DGCL and is not  intended  to be a complete  statement  of the  provisions.  You
should  carefully read the full text of section 262 of the DGCL, a copy of which
is attached hereto as Appendix D and is incorporated herein by reference.


     If the merger is approved by the required vote of NMBT's shareholders,  you
must take the following  actions to exercise  your rights of  appraisal:

     o    file written  notice with NMBT of an  intention to exercise  rights to
          appraisal of your shares prior to the NMBT special  meeting;

     o    do not vote in favor of the merger;

     o    continuously  hold your shares of NMBT through the  effective  time of
          the merger, and

     o    within 20 days after the mailing of notice by Summit of the  effective
          time of the  merger,  make a written  demand  on Summit  for the "fair
          value" of your NMBT  common  stock,  stating  the  number and class of
          shares for which you are demanding payment.

                                       34
<PAGE>


     If you follow all of the  above-stated  conditions,  the fair value of your
shares  of NMBT  common  stock  will be  determined  by the  Delaware  Court  of
Chancery, exclusive of any element of value arising from the merger.

     Within 10 days  after the  effective  date of the  merger,  Summit,  as the
surviving  corporation,  will notify  each  holder of NMBT common  stock who has
complied  with the  conditions  set  forth  above  that the  merger  has  become
effective. Within 120 days after the effective date of the merger, Summit or any
holder of NMBT common stock who has complied with the  applicable  procedures of
the  DGCL,  may  file a  petition  in the  Delaware  Court of  Chancery  for the
appraisal  of the fair  value of the  shares of NMBT  common  stock held by NMBT
shareholders who have exercised  dissenters rights.  Since, at this time, Summit
has not  decided  whether it will file a petition  for  appraisal  if  appraisal
rights are exercised,  a dissenting  shareholder  who desires that a petition be
filed should file a petition  unless  otherwise  notified that Summit or another
dissenting  shareholder has filed a petition for appraisal. A holder may, within
60 days of the  effective  date of the  merger,  withdraw  his or her demand for
appraisal.  Within 120 days of the effective time of the merger,  the holders of
dissenting shares are entitled,  upon written request,  to receive from Summit a
statement  setting  forth the  aggregate  number of shares with respect to which
demands for appraisals have been received.


     If you demand the  appraisal  and purchase of your shares under Section 262
but fail to perfect, or effectively withdraw or lose the right to such purchase,
your shares will be converted  into a right to receive  shares of Summit  common
stock in accordance with the terms of the merger  agreement.  Dissenting  shares
lose their status as dissenting shares if, among other things:

     o    the merger is abandoned;

     o    you  transfer  your NMBT shares prior to  submission  for the required
          endorsement;

     o    you fail to make a timely written demand for appraisal;

     o    you vote in favor of the merger;

     o    neither  Summit nor you file a  complaint  or  intervene  in a pending
          action within 120 days after mailing of the approval notice; or

     o    you  deliver  to  Summit,  as the  surviving  corporation,  a  written
          withdrawal of your demand for appraisal of the  dissenting  shares and
          acceptance  of the merger,  either  within 60 days after the effective
          date of the merger or thereafter with written approval of Summit.

     Failure  to  follow  the  steps  required  by  section  262 of the DGCL for
perfecting appraisal rights may result in the loss of appraisal rights, in which
event you will only be entitled to receive the consideration provided for by the
merger agreement.  In view of the complexity of the provisions of section 262 of
the DGCL, NMBT  shareholders who are considering  objecting to the merger should
consult their own legal advisors.


     Any  NMBT  shareholder  who  properly  exercises   dissenters  rights  will
recognize  taxable gain or loss for federal  income tax purposes upon receipt of
the cash payment in an amount equal to the difference between the amount of cash
received and his or her adjusted tax basis in the NMBT common stock.


NEW YORK STOCK EXCHANGE LISTING

     Summit has agreed in the merger  agreement to use its best efforts to cause
the  shares of Summit  common  stock to be  issued to NMBT  shareholders  in the
merger  to be  listed  on the  New  York  Stock  Exchange.  The New  York  Stock
Exchange's indication that the necessary shares of Summit common stock are to be
listed on the New York Stock  Exchange,  subject to official notice of issuance,
is a condition to the completion of the merger.

ACCOUNTING TREATMENT

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

CERTAIN FEDERAL INCOME TAX CONSEQUENCES OF THE MERGER

     The  following  discussion  is based upon an opinion  of  Thompson  Coburn,
special counsel to Summit, and except as otherwise indicated,  reflects Thompson
Coburn's  opinion.  The  discussion  is a summary of the material  United States
federal income tax consequences of the merger to NMBT  shareholders and is not a
complete analysis or listing of all potential tax considerations or consequences
relevant to a decision whether to vote for the approval of the merger agreement.
The discussion  does not address all aspects of federal income taxation that may
be  applicable  to NMBT  shareholders  in  light  of their  status  or  personal
investment   circumstances,   nor  does  it  address  the  federal   income  tax
consequences of the merger that are applicable to NMBT  shareholders  subject to
special  federal income tax treatment  including,  without  limitation,  foreign
persons, insurance companies,  tax-exempt entities, retirement plans, dealers in
securities,  persons  who  acquired  their NMBT  common  stock  pursuant  to the
exercise of employee stock options or otherwise as compensation, and persons who
hold their NMBT common  stock as part of a  "straddle,"  "hedge" or  "conversion
transaction."  In addition,  the  discussion  does not address the effect of any
applicable  state,  local or foreign tax laws,  or the effect of any federal tax
laws other than those pertaining to the federal income tax. As a result, you are
urged to  consult  with your own tax  advisor  to  determine  the  specific  tax
consequences  of the merger to you. The  discussion  assumes that shares of NMBT
common stock are held as capital  assets  (within the meaning of Section 1221 of
the Internal Revenue Code) at the effective time of the merger.

     NMBT and Summit  have  received an opinion  from  Thompson  Coburn,  to the
effect that, assuming the merger occurs in accordance with the merger agreement,
the merger will  constitute a  "reorganization"  for federal income tax purposes
under Section 368(a)(1) of the Internal Revenue Code, with the following federal
income tax consequences:

     o    You will recognize no gain or loss as a result of the exchange of your
          NMBT common stock solely for shares of Summit common stock pursuant to
          the merger, except with respect to cash received instead of fractional
          shares, if any, as discussed below.

     o    The aggregate  adjusted tax basis of the shares of Summit common stock
          you receive in the merger,  including any  fractional  share of Summit
          common stock  deemed to be  received,  as described in bullet 4 below,
          will be equal to the  aggregate  adjusted  tax basis of the  shares of
          NMBT common stock surrendered.

     o    The holding period of the shares of Summit common stock you receive in
          the merger,  including  any  fractional  share of Summit  common stock
          deemed to be received,  as  described in bullet 4 below,  will include
          the holding period of the shares of NMBT common stock surrendered.

     o    If you receive  cash instead of a  fractional  share of Summit  common
          stock,  you  will be  treated  as if the  fractional  share  had  been
          received and then  redeemed by Summit in return for the amount of cash
          that you received.  You will  recognize  capital gain or loss equal to
          the difference  between the amount of cash received and the portion of
          your adjusted tax basis in the shares of Summit common stock allocable
          to the fractional share.

     The opinion of Thompson  Coburn is subject to the  conditions and customary
assumptions   that  are  stated  in  the   opinion,   and  relies  upon  various
representations  made by Summit  and NMBT.  If any of these  representations  or
assumptions is inaccurate,  the tax consequences of the merger could differ from
those  described in this section.  The opinion of Thompson  Coburn is also based
upon the Internal Revenue Code, regulations proposed or promulgated  thereunder,
judicial  precedent,  and current  administrative  rulings and practice,  all of
which  are  subject  to  change.  Any  such  change,  which  may or  may  not be
retroactive,  could alter the tax  consequences  discussed in this section.  The
receipt of the opinion of Thompson  Coburn  again as of the closing  date of the
merger is a condition to the  completion  of the merger.  An opinion of counsel,
unlike a private letter ruling from the Internal Revenue Service, has no binding
effect.  The  Internal  Revenue  Service  could take a position  contrary to the
opinion of Thompson Coburn and, if the matter were litigated,  a court may reach
a decision  contrary to the opinion.  Neither  Summit nor NMBT has  requested an
advance ruling as to the federal income tax consequences of the merger,  and the
Internal Revenue Service is not expected to issue such a ruling.

     THE FOREGOING IS A SUMMARY OF THE MATERIAL  FEDERAL INCOME TAX CONSEQUENCES
OF THE MERGER TO CERTAIN  NMBT  SHAREHOLDERS  AND DOES NOT TAKE INTO ACCOUNT THE
PARTICULAR  FACTS AND  CIRCUMSTANCES OF EACH NMBT  SHAREHOLDER'S  TAX STATUS AND
ATTRIBUTES.  AS A RESULT, THE FEDERAL INCOME TAX CONSEQUENCES  ADDRESSED IN THIS
DISCUSSION MAY NOT APPLY TO YOU.  ACCORDINGLY,  YOU SHOULD CONSULT WITH YOUR OWN
TAX ADVISOR REGARDING THE SPECIFIC TAX CONSEQUENCES OF THE MERGER, INCLUDING THE
APPLICATION  AND  EFFECT  OF  FEDERAL,  STATE,  LOCAL AND OTHER TAX LAWS AND THE
POSSIBLE EFFECTS OF CHANGES IN FEDERAL AND OTHER TAX LAWS.

RESALE OF SUMMIT COMMON

      The shares of Summit common stock into which your shares of NMBT common
stock are converted at the effective time of the merger will be freely
transferable under the Securities Act of 1933 as amended, unless you are deemed
to be an "affiliate" of NMBT for purposes of Rule 145 under the Securities Act
as of the date of the special meeting. Affiliates of NMBT may not sell their
shares of Summit common stock acquired in connection with the merger except
pursuant to an effective registration statement under the Securities Act
covering the resale of those shares, or in compliance with Rule 145 under the
Securities Act or another applicable exemption from the registration
requirements of the Securities Act. Persons who may be deemed to be affiliates
of NMBT generally include individuals or entities that control, are controlled
by or are under common control with NMBT and may include executive officers and
directors of NMBT as well as principal shareholders of NMBT.

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

DIFFERENCES IN SHAREHOLDERS RIGHTS

Summit is incorporated in the State of New Jersey and NMBT is incorporated in
the state of Delaware. If the merger is consummated, holders of NMBT common
stock will become holders of Summit common stock, and the rights of former NMBT
shareholders will be governed by the NJBCA and Summit's Restated Certificate of
Incorporation and By-Laws. The rights of NMBT stockholders under the DGCL and
NMBT's Restated Certificate of Incorporation and By-Laws differ in certain
significant respects from the rights of Summit shareholders under The NJBCA and
Summit's Restated Certificate of Incorporation and By-Laws. These differences
are summarized in the table below.

(1) Not adjusted to exclude interbank deposits or other transactions among the
    subsidiaries.

           Summit is a legal entity separate and distinct from its subsidiaries.
There are various legal limitations on the extent to which a bank subsidiary may
finance or otherwise supply funds to Summit or its nonbank subsidiaries. Under
federal law, no bank subsidiary may, subject to limited exceptions, make loans
or extensions of credit to, or investments in the securities of Summit or its
non-bank subsidiaries or take their securities as collateral for loans to any
borrower. Each bank subsidiary is also subject to collateral security
requirements for any loans or extensions of credit permitted by such exceptions.

           In addition, bank regulatory limitations exist on the availability of
subsidiary bank undistributed net assets for the payment of dividends to Summit
without the prior approval of the bank regulatory authorities. The Federal
Reserve Act, which affects both Summit Bank (New Jersey) and Summit Bank
(Pennsylvania), restricts the payment of dividends in any calendar year to the
net profit of the current year combined with retained net profits of the
preceding two years. Summit Bank (Connecticut), as a Connecticut chartered bank,
is subject to a similar restriction. Further, Summit Bank (New Jersey), as a New
Jersey state-chartered bank, may declare a dividend only if, after payment, its
capital stock would be unimpaired and its surplus would equal at least 50
percent of its capital stock or its surplus would not be reduced. Summit Bank
(Pennsylvania), as a Pennsylvania-chartered bank, may declare and pay a dividend
only out of accumulated net earnings and only if it has surplus at least equal
to its capital and its surplus would not be reduced by payment of the proposed
dividend. In addition, under the Federal Deposit Insurance Corporation
Improvement Act all institutions are prohibited from paying dividends if after
doing so an institution would be undercapitalized. Summit may not pay dividends
to its shareholders if after paying any dividends it would be unable to pay its
debts as they become due in the usual course of business or its total assets
would be less than its total liabilities. At September 30, 1999, the total
undistributed net assets of Summit's subsidiary banks were $2.8 billion of which
$59.1 million was available under the most restrictive limitations for the
payment of dividends to Summit.

RECENT DEVELOPMENTS


On December 31, 1999, Summit entered into a definitive agreement to acquire
Meeker Sharkey Financial Group, Inc., an insurance brokerage firm which offers
an array of property/casualty products, group health benefits, and retirement
plan services. Summit will issue shares of its common stock to effect the
acquisition. Summit expects to repur-

chase in the open market the number of shares of Summit common stock required to
complete the transaction or reissue shares held in treasury, depending on market
conditions or other factors.

           On January 19,  2000,  Summit  reported net income for the year ended
December 31, 1999 of $442.6 million as compared with $465.8 million for the year
ended  December  31,  1998.  Net income per diluted  share for 1999 was $2.54 as
compared  with  $2.63 for 1998.  Net  income for 1999  reflected  an  additional
provision  for loan losses of $60  million  pretax,  or $.20 per diluted  share,
recorded  in the third  quarter  and a  restructuring  charge  of $27.9  million
pretax,  or $.10 per diluted share,  recorded in the fourth quarter,  associated
with Summit's business  realignment.  Summit's total assets at December 31, 1999
were $36.4 billion as compared with $33.1 billion at December 31, 1998.


                       DESCRIPTION OF SUMMIT CAPITAL STOCK

           Summit is presently  authorized to issue 390,000,000 shares of common
stock  and  6,000,000  shares of  preferred  stock,  without  par  value.  As of
September 30, 1999, there were approximately 174,766,133 shares of Summit common
stock  outstanding,  2,744,256  shares of Summit  common stock held in treasury,
2,000,000  shares of Summit  Series S  preferred  stock  designated  in Summit's
Restated Certificate of Incorporation and reserved for issuance under the Summit
shareholder rights plan described below, and no shares of Summit preferred stock
outstanding. Pursuant to the NJBCA, Summit's board of directors has authority to
set the terms and  conditions of the authorized  but unissued  Summit  preferred
stock.  Summit may issue any authorized Summit common stock and Summit preferred
stock without further  shareholder  vote,  unless a shareholder vote is required
for a particular transaction by applicable law or New York Stock Exchange rules.
Summit  common stock is  presently  listed on the New York Stock  Exchange.  The
issuance of additional Summit common stock or Summit preferred stock,  including
Summit preferred stock that might be convertible into Summit common stock,  may,
among other things,  affect the earnings per share applicable to existing Summit
common  stock and the  equity and voting  rights of  existing  holders of Summit
common stock.


           The following summary is not a complete description of all provisions
relating to Summit capital stock and is subject in all respects to the
applicable provisions of the NJBCA, Summit's Restated Certificate of
Incorporation and Summit's shareholder rights plan.

COMMON STOCK

           The rights of holders of Summit common stock are subject to the
preferences as to dividends and liquidation rights and other prior rights, if
any, of any class or series of Summit preferred stock that may be issued. The
holders of Summit common stock are entitled to one vote for each share with
respect to all matters voted upon by shareholders, including the election of
directors, and are entitled to receive dividends when, as and if declared by
Summit's board of directors out of funds of Summit legally available for the
payment of dividends. Shares of Summit common stock do not have cumulative
voting rights. Accordingly, at any annual meeting of Summit shareholders, or at
any special meeting of shareholders where an election of directors is conducted,
the holders of 50 percent plus one of the shares represented at the meeting,
provided a quorum is present, can fill all positions on Summit's board of
directors that are up for election at that meeting if they so choose. In that
event, the holders of the remaining shares will not be able to fill any
positions on the board up for election at that meeting. Summit has a classified
board of directors, under which approximately one-third of the directors are
elected each year.


           In the event of the liquidation of Summit, holders of Summit common
stock are entitled to share pro rata in the distribution of Summit's assets
available for common shareholders. All shares of Summit common stock are fully
paid and nonassessable. No preemptive rights attach to the ownership of Summit
common stock and no personal liability is imposed on the holders of common stock
by reason of the ownership of those shares. First Chicago Trust Company of New
York, a division of Equiserve is the transfer agent, dividend disbursing agent
and registrar for the Summit common stock. Summit Bank (New Jersey) is the
co-transfer agent.

SHAREHOLDER RIGHTS PLANS

In June, 1999, Summit adopted a shareholder rights plan under which preferred
stock purchase rights ("Rights") attached to Summit common stock outstanding as
of the close of business on August 16, 1999. The shareholder rights plan adopted
in June, 1999 replaced Summit's shareholder rights plan adopted in August, 1989,
which expired August 16, 1999. Holders of shares of Summit common stock issued
subsequent to August 16, 1999

                                       51
<PAGE>

receive the Rights with their shares. Except as indicated below, each Right
entitles the registered holder to purchase from Summit one one-hundredth (1/100)
of a share of a series of Summit preferred stock, designated the Series S
preferred stock ("Summit Series S Preferred"). The Rights expire on August 31,
2009, and are subject to redemption and amendment in certain circumstances. The
Rights trade automatically with shares of Summit common stock and become
exercisable only under certain circumstances as described below.

           The Rights are not currently exercisable. In general, the Rights will
become exercisable upon the earlier to occur of the following: (1) ten days
following a public announcement that a person or group has acquired beneficial
ownership of 15% or more of the Summit common stock outstanding at that time or
voting securities of Summit representing 15% or more of the total voting power
of Summit (such person or group becoming an "Acquiring Person", as defined in
the rights plan) or (2) ten business days, or such later date as Summit's board
of directors may determine, after the commencement of a tender offer or exchange
offer that would result in a person or group beneficially owning 15% or more of
the outstanding Summit common stock or voting securities representing 15% or
more of the total voting power of Summit.


           Generally, in the event the Rights become exercisable by virtue of a
person or group becoming an Acquiring Person, other than pursuant to an offer
for all outstanding shares of Summit common stock and other voting securities
that Summit's board of directors determines to be fair to shareholders and
otherwise in the best interests of Summit, each Right, other than Rights owned
by the Acquiring Person, will entitle the holder to receive, upon exercise of
the Right and payment of the exercise price, Summit Series S Preferred having a
value equal to two times the exercise price of the Right.

           In the event that the Rights become exercisable and Summit is
acquired in a merger or other business combination, or 50% or more of Summit's
assets or earning power is transferred in one or a series of transactions, each
Right will entitle the holder to receive, upon the exercise of the Right, common
stock of the acquiror having a value equal to two times the exercise price of
the Right.


           The provisions contained in Summit's Restated Certificate of
Incorporation relating to the Series S preferred stock may not be amended in a
manner which adversely affects the holders of Series S preferred stock without
the affirmative vote of the holders of two-thirds of the outstanding shares of
Series S preferred stock.

           The combination of prohibitive dilution of the Acquiring Person's
share values and the power of Summit's board of directors to redeem the Rights
is intended to encourage potential acquiring persons to negotiate with Summit's
board of directors with respect to the terms of any acquisition or business
combination and, to the extent possible, discourage or defeat partial or
two-tiered acquisition proposals.

           The foregoing description of the rights plan is not complete and is
qualified in its entirety by reference to the terms of the rights plan, which
are more fully described in Summit's Registration Statement on Form 8-A filed
with the Securities and Exchange Commission on July 27, 1999.

ended  December 31, 1999 of $3.6  million as compared  with $3.2 million for the

                        DESCRIPTION OF NMBT CAPITAL STOCK

GENERAL

           NMBT is authorized to issue 8,000,000 shares of common stock, and
2,000,000 shares of preferred stock. As of September 30, 1999, 2,668,558 shares
of NMBT common stock were issued and outstanding. No shares of NMBT preferred
stock are currently issued or outstanding.

           The following summary does not purport to be complete and is subject
in all respects to the applicable provisions of the DGCL, and NMBT's Amended and
Restated Certificate of Incorporation and Bylaws.

           Authorized but unissued shares of NMBT capital stock may be used for
various purposes, including stock splits and dividends, potential acquisitions,
public offerings, stock option and employee stock plans and dividend
reinvestment plans. Authorized but unissued shares of capital stock, or
securities convertible into or exchangeable for such capital stock, could also
be issued by the board of directors in a manner that could make a change in
control more difficult. Under certain circumstances, such shares could be sold
privately to purchasers who might support the board of directors in opposing a
takeover bid that it determines not to be in the best interest of the
shareholders.

           Each holder of NMBT common stock is entitled to one vote for each
share held. The shares of common stock do not have cumulative voting rights.
Holders of NMBT common stock do not have preemptive rights to subscribe for or
purchase shares of any class of capital stock now or hereafter authorized or
securities convertible into shares of any class of capital stock.

           Holders of NMBT's common stock are entitled to receive dividends
when, as and if declared by the board of directors. Dividends may be declared
and paid only out of funds legally available therefore. In the event of
liquidation of NMBT, holders of NMBT common stock are entitled to share pro rata
in the net assets of NMBT remaining after payment of all amounts due creditors.

                  PROPOSAL II -- ADJOURNMENT OF SPECIAL MEETING

           In the event there are not sufficient votes to constitute a quorum
for the special meeting or to approve the merger agreement at the time of the
special meeting, the merger agreement could not be approved unless the special
meeting was adjourned in order to permit further solicitation of proxies. In
order to allow proxies that have been received by NMBT at the time of the
special meeting to be voted for adjournment under these circumstances, NMBT has
submitted the question of adjournment to its shareholders as a separate matter
for their consideration. In order to approve any adjournment a majority of the
shares entitled to vote must be cast in favor of Proposal 2.

           NMBT's board of directors recommends that shareholders vote their
proxies FOR the adjournment proposal so that their proxies may be used for
purposes of adjourning the special meeting under the circumstances described in
the preceding paragraph.

           Properly executed proxies will be voted in favor of adjournment
unless otherwise indicated thereon. However, proxies voting AGAINST the merger
agreement will not be voted in favor of the adjournment proposal unless the
shareholder has voted FOR approval of the adjournment proposal on the proxy
card.

                              SHAREHOLDER PROPOSALS

           NMBT shareholders will not be entitled to submit proposals for
consideration at the special meeting except to the extent the proposals relate
directly to the matters to come before the special meeting as set forth in this
Proxy Statement-Prospectus. If the merger is not approved at the special meeting
and NMBT subsequently holds its annual meeting for 2000, NMBT shareholders will
be entitled to submit proposals on matters appropriate for shareholder action
consistent with regulations of the Securities and Exchange Commission and NMBT's
Bylaws. No date has been set for NMBT's 2000 annual meeting of shareholders.

           Summit's By-Laws provide that shareholder proposals which do not
appear in the proxy statement may be considered at a meeting of shareholders
only if written notice of the proposal is received by the Secretary of Summit
not less than 80 and not more than 100 days before the anniversary of the
preceding year's annual meeting. However, if the date of the annual meeting is
more than 30 days before or more than 60 days after that anniversary date, the
notice of a shareholder proposal, to be timely, must be received by the
Secretary not later than the close of business on the later of the 80th day
prior to the annual meeting or the tenth day following the day on which public
announcement of the meeting date is first made. Any notice of a shareholder
proposal by a shareholder to the Secretary of Summit must be accompanied by:

           o the name and address of the shareholder who intends to present the
             proposal for a vote;

           o a representation that the shareholder is a holder of record of
             shares entitled to vote at the meeting;

           o a description of all agreements, arrangements or understandings
             between the shareholder and any other shareholder relating to the
             proposal to be voted on and any financial or contractual interest
             of either shareholder in the outcome of the vote; and

           o all other information regarding the proposal to be voted on and
             the shareholder intending to present the proposal for a vote as
             would be required to be included in a proxy statement soliciting
             the vote of shareholders in respect of the proposal pursuant to
             the proxy rules of the Securities and Exchange Commission.

           Summit's board of directors will consider and include in Summit's
proxy statement for the 2000 annual meeting of Summit shareholders proposals
which meet the regulations of the Securities and Exchange Commission and New
Jersey law and which comply with Summit's By-laws. In order to be eligible for
inclusion, proposals were required to be addressed to Summit's Secretary and
must have been received on or before November 9, 1999.

                                 OTHER MATTERS

NMBT's board of directors is not aware of any business to come before the
special meeting other than those matters described in this Proxy
Statement-Prospectus. However, if any other matters should properly come before
   the special meeting, the proxy holders intend to vote on those matters in
accordance with their reasonable business judgment.

                                 LEGAL MATTERS

                                   ARTICLE I.
                               GENERAL PROVISIONS

       Section 1.01.       The Reorganization.

       (a) Upon the  terms  and  subject  to the  conditions  contained  in this

accordance  with the  provisions  of, and with the effect  provided  in, the New
Jersey Business  Corporation Act, as amended ("New Jersey Act") and the Delaware
General Corporation Law, as amended ("Delaware Law"); or

              (2) NMBT shall be merged into a wholly owned  subsidiary of Summit
or a wholly owned subsidiary of Summit shall be merged into NMBT, in either case
pursuant  to and in  accordance  with the  provisions  of,  and with the  effect
provided in, the corporate laws of the  jurisdiction of incorporation of each of
the constituent corporations in such merger ("Applicable Corporation Laws").

                                      A-1
<PAGE>



and following an election of the  Reorganization  method provided for at Section
1.01(a)(2)  Summit  shall  (i)  cause  the  wholly  owned  subsidiary  of Summit
designated as the  constituent  corporation in the  Reorganization  ("Designated

with all Applicable  Corporation  Laws, (ii) cause this Agreement to be approved

Exhibit A to this  Agreement  (A) any  additional  terms and  conditions to this
Agreement  required by Applicable  Corporation Laws to effect the Reorganization
and  other  transactions  contemplated  by this  Agreement,  (B) the  terms  and
conditions of any agreement or plan of merger required by Applicable Corporation
Laws,  (C) the date and time that the merger shall be effective or the mechanism
for  determining  the date and time that the merger shall be  effective  and (D)
such other terms and  conditions as Summit shall  determine in its discretion to
be desirable and not contrary to this Agreement or Applicable  Corporation  Laws
regarding  the  corporate  governance  of the  corporation  surviving the merger
contemplated  by  Section  1.01(a),   including  without  limitation  terms  and
conditions  governing  certificates or articles of incorporation  and amendments
thereto or restatements thereof, by-laws of the corporation surviving the merger
and amendments thereto, and directors and officers of the corporation  surviving
the merger; provided, however, that no provision of Exhibit A shall (x) alter or
change the amount or kind of consideration  to be received by NMBT  Shareholders
(as defined at Section  1.07(c)  below) as provided for in this Agreement on the
date  hereof,  (y)  adversely  affect the tax  treatment  of the  Reorganization

Shareholders or (z) materially impede or delay  consummation of the transactions
contemplated by this Agreement and (iv) cause the Designated  Summit  Subsidiary
to take all actions  appropriate to accomplish the  Reorganization and the other
transactions  contemplated by this Agreement.  Exhibit A as so constituted shall
constitute a part of this  Agreement as fully as if attached  hereto on the date
hereof without separate execution by Summit or NMBT.

       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
June 16, 1999 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 NMBT Capital Stock.

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

              (1) All shares of the Common Stock,  par value $0.01 per share, of
NMBT  ("NMBT  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 NMBT or a subsidiary of
NMBT (other than NMBT Stock held as a result of foreclosures or debts previously
contracted  and  NMBT  Stock  held in  fiduciary,  discretionary  and  custodial
accounts and other representative  capacities),  if any, or held in the treasury
of NMBT, if any, shall be canceled and retired and no cash,  securities or other
consideration  shall be payable or paid or  delivered  under this  Agreement  in
exchange for such NMBT Stock; and

              (2)  Subject to  Section  1.03(a)(1),  outstanding  shares of NMBT
Stock held as of the

                                        A-2

<PAGE>



Effective Time by each NMBT  Shareholder  shall be converted in accordance  with
the New Jersey Act and the Delaware  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 NMBT  Stock  held by each  NMBT
Shareholder  shall be  multiplied  by the Exchange  Ratio (as defined at Section
1.03(c) below) and (i) a NMBT 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) an
NMBT 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 NMBT 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 NMBT Stock shall be  appropriately  adjusted to give effect to the
Capital Change.

       (c) The "Exchange Ratio" is hereby defined to be the number determined in
accordance with the following provisions of this Section 1.03(c):

              (A)   If the  Summit  Price (as  defined  at  Section  9.02(e)(ii)
                    below) is greater than  $37.01563,  the Exchange Ratio shall
                    be 0.7024;

              (B)   If the Summit  Price is equal to or greater  than  $27.35938
                    and  equal to or less than  $37.01563,  the  Exchange  Ratio
                    shall be equal to the quotient  obtained by dividing  $26.00
                    by the Summit Price; and

              (C)   If the Summit  Price is less than  $27.35938,  the  Exchange
                    Ratio shall be 0.9503.

       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 NMBT 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 NMBT Shareholders.

         Section 1.05. Exchange Agent Arrangements. Prior to the Effective Time,
Summit shall

                                       A-3

<PAGE>



appoint  Equiserve - First Chicago Trust Division,  or another entity reasonably
satisfactory to NMBT, 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 NMBT Stock ("NMBT Certificates") and Summit shall deliver
to the  Exchange  Agent  sufficient  Summit  Certificates  and  cash as shall be
required to satisfy  Summit's  obligations  to NMBT  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 NMBT 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 certificate
of merger of Summit and NMBT filed with the  Secretary  of State of the State of
Delaware  ("Delaware  Certificate")  filed in accordance with Section 252 of the
Delaware  Law,  which  such  hour and date  shall  be  identical  in both the NJ
Certificate  and the  Delaware  Certificate.  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 NMBT Certificates.

       (a) After the Effective Time and subject to Section  1.07(c) below,  each
NMBT Shareholder  (except as provided  otherwise in Section  1.03(a)(1)  above),
upon surrender to the Exchange Agent of all NMBT Certificates  registered to the
NMBT  Shareholder,  shall be entitled  to receive in exchange  therefor a Summit
Certificate  representing  the number of whole  shares of Summit Stock such NMBT
Shareholder  becomes entitled to receive pursuant to Section  1.03(a)(2) and the
Cash In Lieu Amount, payable by check, such NMBT Shareholder may become entitled
to receive  pursuant to Section  1.03(a)(2).  Until so surrendered,  outstanding
NMBT Certificates  held by each NMBT  Shareholder,  other than NMBT Certificates
governed by Section 1.03(a)(1),  shall be deemed for all purposes (other than as
provided  below with respect to  unsurrendered  NMBT  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  NMBT
Certificates dividends or other distributions,  if any, on Summit Stock declared
after  the  Effective  Time;  provided,  however,  that upon the  surrender  and
exchange of NMBT  Certificates  following a dividend  or other  distribution  on
Summit Stock there shall be paid to such NMBT  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 NMBT  Certificates as of the Effective Time shall cease to
be, and shall have no further rights as, shareholders of NMBT.

       (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 NMBT Stock as of the Effective Time ("NMBT  Shareholders")
(including the address and social security number of and the number of shares of
NMBT Stock held by each NMBT Shareholder) from NMBT ("Final  Shareholder List"),
Summit  shall  cause  the  Exchange  Agent  to  send to  each  NMBT  Shareholder
instructions  and transmittal  materials for use in surrendering  and exchanging
NMBT Certificates for

                                        A-4

<PAGE>



the Reorganization Consideration. If NMBT 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 NMBT cause the Exchange Agent to cancel and exchange NMBT
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 NMBT, must suspend the exchange  process  provided for in the second sentence
of this Section  1.07(c) in order to preserve and report the required  reporting
information,  the 10-day exchange  requirement shall be extended 5 business days
for exchanges being processed by the Exchange Agent at the  commencement  of, or
which are received during, the period of the suspension.

       (d) At and after the  Effective  Time there shall be no  transfers on the
stock transfer books of NMBT of the shares of NMBT 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.       NMBT Stock Options.

       (a) At the  Effective  Time,  each NMBT  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  ("Converted   Options")  and  each  Converted  Option  (i)  shall
immediately vest to the extent the related NMBT Option was vested or as provided
in the NMBT Stock  Compensation  Plan (as defined at Section  2.01(d)(3)  below)
under  which the  related  NMBT  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 NMBT Stock Compensation Plan under which the related NMBT Option was granted
and in the stock option agreement by which it was evidenced;  provided, however,
that the following two

                                        A-5

<PAGE>



revisions  shall be made:  (A) Converted  Options held by any  Converted  Option
holder whose employment with Summit  terminates within one year of the Effective
Time,  other  than due to a  termination  by  Summit  for  cause,  shall  remain
exercisable  until the  later to occur of the  exercisability  termination  date
provided for in the particular  Converted Option or the first anniversary of the
Effective  Date;  provided  further,  however,  that no Converted  Option may be
exercised beyond the expiration date of the particular Converted Option; and (B)
Converted  Option  holders  shall have the right,  exercisable  only for 30 days
following the Effective  Time, in lieu of exercising all Converted  Options then
outstanding,  to elect to receive from Summit,  with respect to all  outstanding
Converted  Options then held by such holders,  a cash lump sum  representing the
aggregate  difference  between the exercise price of their Converted Options and
the Summit  Price.  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
NMBT Stock which would have been  issuable  upon exercise in full of the related
NMBT 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  NMBT  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  NMBT  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 NMBT
Options,  all  information  about  the  NMBT  Options  and the  holders  thereof
(including  the  address  and social  security  number of each such holder and a
description  of the NMBT 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 NMBT Stock subject
thereto)  and  copies of each form of option  agreement,  warrant  agreement  or
letter agreement entered into between NMBT and a holder of a NMBT Option (all of
the  foregoing  being  collectively  referred  to as the "Final  Option List and
Materials"),  Summit shall issue to the holders of such NMBT 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 NMBT 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 NMBT shall have delivered to
Summit the Final Option List and Materials. 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, NMBT 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, "NMBT Option" is hereby defined to
mean  an  option  relating  to the  purchase  of  NMBT  Stock,  and  any  rights
appurtenant  thereto  including  Equity  Based  Rights  (as  defined  at Section
2.01(d)(2)  below),  granted under a NMBT Stock Compensation Plan (as defined at

expiration   of  one  year   following  the   Effective   Time,   Reorganization
Consideration  remains  with  the  Exchange  Agent  due to the  failure  of NMBT

amount as Summit may determine is reasonably  necessary as indemnity against any
claim that may be made  against it with  respect to such NMBT  Certificate,  the
Exchange  Agent will issue in exchange for such lost,  stolen or destroyed  NMBT
Certificate  the  Reorganization  Consideration  deliverable in respect  thereof
pursuant to this Agreement.

right  convertible  into or  exchangeable  for the capital stock or other equity
security or equity interests of such issuer,  and (iii) contracts,  commitments,
obligations,  agreements,  understandings  or arrangements  entitling  anyone to
acquire  from the  issuer,  or by which such  issuer is or may  become  bound to

receiving  deposits and making loans).  Bank is a bank duly  organized,  validly
existing,  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 it  transacts  business,  except where the failure to be so
qualified is not reasonably be expected to have a NMBT Material  Adverse Effect.

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,

orders.

       (f) The authorized and outstanding  capital stock of Bank is as set forth
on NMBT Schedule 2.01(f).  NMBT 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

notes and schedules  thereto)  contained in or  incorporated  by reference  into
NMBT's (a) annual report to shareholders  for the fiscal year ended December 31,
1998, (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,
1998 and (c) quarterly  reports on Form 10-Q filed  pursuant to the Exchange Act
for the  fiscal  quarters  ended  March 31,  1999 and June 30,  1999 (the  "NMBT
Financial Statements") are true and correct in all material respects as of their
respective  dates and each fairly  presents  (subject,  in the case of unaudited
statements,  to recurring  audit  adjustments  normal in nature and amount),  in
accordance  with generally  accepted  accounting  principles,  the  consolidated
statements of condition,  income, changes in stockholders' equity and cash flows
of NMBT 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 NMBT 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 NMBT 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 NMBT Schedule  2.03,
NMBT 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

consummation   of   the   transactions   contemplated   hereby   including   the
Reorganization  by NMBT 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 NMBT or any
of its  subsidiaries or upon any of the Equity  Securities of NMBT or any of its
subsidiaries, or constitute an event which could, with the lapse of time, action
or inaction by NMBT 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 NMBT or any of its
                subsidiaries;

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

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

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

to which NMBT or any of its  subsidiaries  is a party or by which NMBT or any of
its  subsidiaries  or any of their assets or properties  are bound or committed,
the consequences of which individually or

                                       A-10

<PAGE>



in the aggregate  could  reasonably be expected to result in a material  adverse
change in the business, results of operations,  assets or financial condition of
NMBT and its subsidiaries,  on a consolidated  basis, from that reflected in the
NMBT  Financial  Statements  as of and for the six months  ended  June 30,  1999
("NMBT  Material  Adverse   Change"),   or  enable  any  person  to  enjoin  the
transactions contemplated hereby.

       Section  2.04.   Absence  of  Undisclosed   Liabilities.   NMBT  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 NMBT 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 NMBT  Financial  Statements or disclosed in the notes  thereto,
(b) commitments  made by NMBT or any of its  subsidiaries in the ordinary course
of its  business  which  are  not in the  aggregate  material  to  NMBT  and its
subsidiaries,  on a  consolidated  basis,  and (c)  liabilities  arising  in the
ordinary  course  of its  business  since  June 30,  1999,  which are not in the
aggregate material to NMBT and its subsidiaries,  on a consolidated basis. Other
than as may be set  forth on NMBT  Schedule  2.04,  neither  NMBT nor any of its
subsidiaries  has, since June 30, 1999, 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 Boston 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  NMBT or any of its  subsidiaries
which  materially  and  adversely  affects  NMBT  and  its  subsidiaries,  on  a
consolidated  basis, and there are no actions,  arbitrations,  claims,  charges,
suits,  investigations or proceedings  (formal or informal) material to NMBT and
its  subsidiaries,  on a consolidated  basis,  pending or, to NMBT's  knowledge,
threatened,  against  or  involving  NMBT 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 NMBT  referred  to in  Section  2.02.  Neither  NMBT  nor any
subsidiary of NMBT is a party to any  agreement or  memorandum of  understanding
with,  or is a party to any  commitment  letter to, or has  submitted a board of
directors  resolution or similar  undertaking  to, or is subject to any order or
directive by, or is a recipient of any  extraordinary  supervisory  letter from,
any governmental or regulatory  authority which restricts materially the conduct
of its business,  or in any manner  relates to material  statutory or regulatory
noncompliance discovered in any regulatory  examinations,  its capital adequacy,
its  credit  or  reserve  policies  or its  management.  Neither  NMBT  nor  any
subsidiary of NMBT 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 NMBT nor
any  subsidiary  of NMBT  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 NMBT's or a
NMBT  subsidiary's  business nor has NMBT or any subsidiary of NMBT been advised
of any  significant  deficiencies  by any such  agency  in  connection  with any
current examination of either NMBT or a subsidiary of NMBT by any such agency.

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

       Section  2.07.  Regulatory  Filings.  All  filings  made by NMBT  and its
subsidiaries  after  December  31,  1995 with the SEC and the  appropriate  bank
regulatory  authorities did not contain any untrue  statement of a material fact
and did not omit to state any  material  fact  required  to be stated  herein or
therein or necessary to make the statements  contained 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  NMBT  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.  NMBT 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 NMBT of
this  Agreement,  the  Reorganization  and the other  transactions  contemplated
hereby in accordance with NMBT's Amended and Restated Certificate  Incorporation
and the  Delaware  Law at a meeting of such  holders to be duly called and held,
NMBT 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
NMBT has taken all action required by law, its Amended and Restated  Certificate
Incorporation,  its By-Laws or otherwise  (i) to  authorize  the  execution  and
delivery of this  Agreement  and (ii) for  shareholders  of NMBT 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 NMBT  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 NMBT in authorizing the execution
of this  Agreement has determined to recommend to the  shareholders  of NMBT the
approval  of this  Agreement,  the  Reorganization  and the  other  transactions
contemplated  hereby,  subject to the proviso  appearing in the last sentence of
Section 4.03 hereof.

       Section  2.09.  Absence of  Changes.  There has not been,  since June 30,
1999,  any NMBT  Material  Adverse  Change.  Except  as may be set forth in NMBT
Schedule 2.09, neither NMBT nor any of its subsidiaries has since June 30, 1999:
(a) (i)  declared,  set  aside or paid any  dividend  or other  distribution  in
respect of its Equity Securities, other than dividends from subsidiaries to NMBT
or other subsidiaries of NMBT, an ordinary cash dividend to NMBT shareholders of
$0.10  per share or less per  fiscal  quarter  and the  dividends  provided  for
herein,  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

                                       A-12

<PAGE>



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  $50,000,
whether or not covered by insurance,  adversely affecting its business, property
or assets, or waived any rights of value in excess of $50,000;  (f) entered into
transactions  other  than  in the  ordinary  course  of  business  which  in the
aggregate exceeded $100,000;  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  June  30,  1999  and
thereafter the allowances  for credit losses of NMBT 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 NMBT's  knowledge,  the loan and lease
portfolios of NMBT in excess of such  allowances are collectible in the ordinary
course of  business.  NMBT  Schedule  2.10  constitutes  a list of all loans and
leases made by NMBT or any of its subsidiaries that have been "classified" as to
quality by any internal or external  auditor,  accountant or examiner,  and such
list is accurate and complete in all material respects.

       Section  2.11.  Taxes  and  Tax  Returns.  Neither  NMBT  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 NMBT 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 NMBT 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 NMBT 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 NMBT or
any of its subsidiaries,  have been paid in full or adequate  provision therefor
has been included on the books of NMBT or its appropriate subsidiary. Other than
franchise tax returns filed by NMBT with the State of Delaware, neither NMBT nor
any of its  subsidiaries  is required  to file tax returns  with any state other
than the State of  Connecticut.  Provision has been made on the books of NMBT or
its appropriate  subsidiary for all unpaid taxes, whether or not disputed,  that
may become due and payable by NMBT 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. Neither the Internal Revenue Service ("IRS") nor the
State  of  Connecticut  has  audited  any  income  tax  returns  of  NMBT or its
subsidiaries. Neither NMBT nor any of its subsidiaries is subject to an audit or
review of its tax returns by any state other than the State of Connecticut. NMBT
is not and has not been a United States real  property  holding  corporation  as
defined in Section  897(c)(2) of the Code during the applicable period specified
in  Section   897(c)(1)(A)(ii)  of  the  Code.  Neither  NMBT  nor  any  of  its
subsidiaries is currently a party

                                       A-13

<PAGE>



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 NMBT's knowledge,  threatened against NMBT or any of
its  subsidiaries,  including  a  claim  or  assessment  by any  authority  in a
jurisdiction  where NMBT or any of its  subsidiaries do not file tax returns and
NMBT 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 NMBT 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 NMBT or any of its  subsidiaries,  and neither NMBT nor any of its
subsidiaries  has any knowledge that the IRS has proposed any such adjustment or
change in  accounting  method.  NMBT 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. NMBT 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 NMBT Financial  Statements (except
individual properties and assets disposed of since June 30, 1999 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
NMBT Financial  Statements or which in the aggregate do not materially adversely
affect or impair the operation of NMBT and its  subsidiaries  on a  consolidated
basis.  NMBT  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 NMBT  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 NMBT and its  subsidiaries,  on a
consolidated basis.

       Section 2.13. Condition of Properties;  Insurance.  All real and tangible
personal  properties owned or leased by NMBT 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 NMBT or such  subsidiary  subject  to
exceptions  which  are  not,  in  the  aggregate,   material  to  NMBT  and  its
subsidiaries,  on a  consolidated  basis.  NMBT  and  each  of its  subsidiaries
maintains insurance (with companies which, to the best of NMBT's knowledge,  are
approved by all appropriate  state  insurance  regulators to sell such insurance
where purchased by NMBT) against loss relating to such properties and such other
risks as companies engaged in similar business located in Connecticut, 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

                                       A-14

<PAGE>



in an amount and form and are otherwise adequate to protect NMBT and each of its
subsidiaries  from  any  adverse  loss  resulting  from  risks  and  liabilities
reasonably  foreseeable  at the date hereof,  and are disclosed on NMBT Schedule
2.13.  All  material  claims  thereunder  have  been  filed in a due and  timely
fashion.  Since December 31, 1994,  neither NMBT 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 NMBT 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 NMBT Schedule 2.14(a), neither NMBT nor any of
its  subsidiaries  is a party to and  neither  they nor any of their  assets are

or personal,  as tenant or licensee involving an annual  consideration in excess
of $50,000.

       (b) Except as set forth in NMBT Schedule 2.14(b), neither NMBT 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 NMBT bargaining  contract or union agreement) or other
agreement  with any  director  or any  officer or other  employee of NMBT or any
subsidiary,  the  benefits  of which are  contingent,  or the terms of which are
materially altered,  upon the occurrence of a transaction  involving NMBT or any
of its  subsidiaries  of the nature  contemplated by this Agreement which is not
terminable without penalty by NMBT or a subsidiary,  as appropriate,  on 60 days
or less notice;  (ii) contract or commitment for capital  expenditures in excess
of $50,000 for any one project or in excess of $100,000 in the aggregate for all
projects;  (iii) contract or commitment whether for the purchase of materials or

$50,000  (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 $50,000; (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 NMBT 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 NMBT  (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 NMBT or any of its  subsidiaries,  (viii)
contract  (other  than  this  Agreement)  limiting  the  freedom  of NMBT 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 NMBT and
its subsidiaries,  on a consolidated  basis, and not made in the ordinary course
of business.

       (c) Neither NMBT 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

                                       A-15

<PAGE>



opinion of management of NMBT, is materially adverse, onerous, or harmful to any
aspect of the business of NMBT and its subsidiaries, on a consolidated basis.


       Section 2.15.       Pension and Benefit Plans.

       (a)  Neither  NMBT  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 NMBT Schedule
2.15(a)  (individually a "NMBT Pension Plan" and  collectively the "NMBT Pension
Plans").  In its present form each NMBT  Pension  Plan  complies in all material
respects with all applicable  requirements  under ERISA and the Code (except for
amendments,  if any, required by legislative or regulatory changes but for which
the applicable remedial amendment period has not yet expired). Each NMBT Pension
Plan which is intended to be  qualified  and exempt  under  Sections  401(a) and
501(a) of the Code,  and the trust  created  thereunder,  are so  qualified  and
exempt  and NMBT or the  subsidiary  whose  employees  are  covered by such NMBT
Pension Plan has received from the IRS a determination  letter or opinion letter
to that  effect and such  determination  letter or  opinion  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 (other than the
failure of NMBT or a NMBT subsidiary, or prototype plan sponsors, if applicable,
to adopt amendments,  if any, required by legislative or regulatory  changes but
for which the applicable  remedial  amendment period has not yet expired).  Each
NMBT Pension Plan has been administered and communicated to the participants and
beneficiaries  in  accordance  with its terms and  ERISA,  except  for  defects,
failures or omissions in  administration  or operation that could not reasonably
be expected to result in a material adverse effect. No employee or agent of NMBT
or any subsidiary whose employees are covered by a NMBT 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 NMBT Pension Plan's  qualification  and the
associated  trust's  exemption (other than the failure to adopt  amendments,  if
any, required by legislative or regulatory  changes but for which the applicable
remedial  amendment period has not yet expired) or impose any material liability
or material  penalty under the Code, or (ii) a participant  or  beneficiary or a
nonparticipating  employee has been denied benefits properly due under such NMBT
Pension  Plan in a manner  that  could  reasonably  be  expected  to result in a
material liability being imposed on NMBT or any NMBT subsidiary. No NMBT Pension
Plan is  currently  or has at any time after  December  31, 1995 been subject to
Section 412 of the Code or Title IV of ERISA. To NMBT's knowledge, no person has
engaged  in any  prohibited  transaction  involving  any  NMBT  Pension  Plan or
associated  trust  within the meaning of Section 406 of ERISA or Section 4975 of
the Code. There are no pending, or to NMBT's knowledge, threatened claims (other
than  routine  claims  for  benefits)  against  the  NMBT  Pension  Plans or any
fiduciary  thereof  which would  subject  NMBT or any of its  subsidiaries  to a
material  liability.  All reports,  filings,  returns and  disclosures and other
communications  relating to any NMBT Pension Plan which have been required to be
made  to the  participants  and  beneficiaries,  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.  "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  NMBT is a  member  and  which is under  common
control  within the meaning of Section 414 of the Code.  Neither NMBT 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.

                                       A-16

There  are  no  unfunded  benefit  or  pension  plans  or  arrangements,  or any
individual  agreements  whether  qualified  or not,  to which NMBT or any of its
subsidiaries  or ERISA  Affiliates  has any  obligation to  contribute.  No NMBT
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 NMBT Pension Plan.

       (b)  All  bonus,  deferred  compensation,   profit-sharing,   retirement,
pension,  stock  option,  stock  award  and stock  purchase  plans and all other
employee  benefit,  health  and  welfare  plans,   arrangements  or  agreements,
including  without  limitation  the NMBT Stock  Compensation  Plans and medical,
major medical,  disability,  life  insurance or dental plans covering  employees
generally,  other than the NMBT Pension Plans,  maintained by NMBT or any of its
subsidiaries  with an  annual  cost in  excess of  $50,000  (collectively  "NMBT
Benefit  Plans") are listed in NMBT Schedule  2.15(b)  (unless already listed in
NMBT Schedule  2.15(a) or NMBT 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 NMBT Benefit Plans have been  administered  and communicated to
the  participants  and  beneficiaries  in accordance with their terms and ERISA,
except for defects,  failures or omissions in  administration or operations that
could not  reasonably  be expected to result in a material  adverse  effect.  No
employee or agent of NMBT 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,  a
participant  or  beneficiary  or a  nonparticipating  employee  has been  denied
benefits  properly  due  under the NMBT  Benefit  Plans in a manner  that  could
reasonably be expected to result in a material  liability  being imposed on NMBT
or any NMBT subsidiary. There are no pending, or to NMBT's knowledge, threatened
claims (other than routine  claims for benefits)  against the NMBT Benefit Plans
which would subject NMBT or any of its subsidiaries to a material 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 relating to
the  NMBT  Benefit  Plans   required  to  be  made  to  the   participants   and
beneficiaries,  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.

       (c) There is no pending or, to NMBT's knowledge,  threatened  litigation,
administrative  action or  proceeding  relating to any NMBT Benefit Plan or NMBT
Pension  Plan.  There  has been no  announcement  or  commitment  by NMBT or any
subsidiary  of NMBT to create an  additional  NMBT  Benefit Plan or NMBT Pension
Plan,  or to  amend a NMBT  Benefit  Plan  or  NMBT  Pension  Plan,  except  for
amendments  required by applicable law, which would materially increase the cost
of such  NMBT  Benefit  Plan or NMBT  Pension  Plan.  Except  for any  plans  or
amendments  expressly  described  on NMBT  Schedule  2.01(d)(3),  NMBT  Schedule
2.15(a) or NMBT  Schedule  2.15(b),  NMBT and its  subsidiaries  do not have any
obligations  for  post-retirement  or  post-employment  benefits  under any NMBT
Benefit Plan  (exclusive of any coverage  mandated by the  Consolidated  Omnibus
Reconciliation  Act of 1986  ("COBRA")  or any similar  state law that cannot be
amended or terminated  upon more than sixty (60) days' notice without  incurring
any liability  thereunder.  NMBT Schedule 2.15(c) consists of the following with
respect  to each  NMBT  Benefit  Plan  and  NMBT  Pension  Plan,  to the  extent
applicable: (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 NMBT
Benefit Plan or NMBT 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, and
(E) 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, 1992, NMBT and each of
its  subsidiaries  has  continuously  maintained  fidelity  bonds  insuring them
against acts of dishonesty in such amounts as are  customary,  usual and prudent
for organizations of its size and business.  All material claims thereunder have
been filed in a due and timely  fashion.  Since December 31, 1992, 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, an amount equal to the
deductible in effect with respect to the claim,  which such  deductible  did not
exceed  $150,000) and neither NMBT nor any of its  subsidiaries  is aware of any
facts  which  would  form the  basis  of a claim  or  claims  under  such  bonds
aggregating  in excess of the  applicable  deductible  amounts under such bonds.
Neither  NMBT  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 NMBT's and its subsidiaries' past claim experience.

       Section  2.17.  Labor  Matters.  Hours  worked  by and  payment  made  to
employees of NMBT 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 NMBT 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 NMBT or its  appropriate  subsidiary.  NMBT  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 NMBT 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  NMBT  or  any  of  its
subsidiaries.  Since  December  31,  1994,  no  employee  of  NMBT 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 NMBT 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 NMBT pending with, or, to
the  knowledge  of NMBT,  threatened  by,  any  labor  organization  or group of
employees of NMBT.

       Section 2.18. Books and Records. The minute books of NMBT 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 NMBT and each of its subsidiaries  fairly and accurately  reflect
the  transactions  to which NMBT 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
of customers (a) is owed by NMBT or any  subsidiary of NMBT an aggregate  amount
equal to more than 5% of the  shareholders'  equity  of NMBT or such  subsidiary
(including deposits, other debts and contingent liabilities) or (b) owes to NMBT
or any of its  subsidiaries  an  aggregate  amount  equal to more than 5% of the
shareholders'  equity  of NMBT or such  subsidiary  (including  loans  and other
debts, guarantees of debts of third parties, and other contingent liabilities).

       Section  2.20.  Trademarks  and  Copyrights.  Neither NMBT nor any of its
subsidiaries  has received  information  that the manner in which NMBT or any of
its subsidiaries conducts its business including its current use of any material
trademark,  trade name,  service mark or copyright  could be in violation of the
asserted rights of others in any trademark,  trade name, service mark, copyright
or

                                       A-18

other proprietary right.

       Section 2.21. Equity Interests.  Neither NMBT nor any of its subsidiaries
owns,  directly or indirectly,  except for the equity  interests of NMBT in Bank
and  the  equity  interests  disclosed  on NMBT  Schedule  2.01(a),  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
$25,000 acquired in connection with a foreclosure or debt previously contracted.
None of the investments  reflected in the consolidated  balance sheet of NMBT as
of  June  30,  1999,  and  none  of  such  investments  made by it or any of its
subsidiaries since June 30, 1999, 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  NMBT  or  any  of  its
subsidiaries.

       Section 2.22.       Environmental Matters.

       (a) Except as disclosed on NMBT  Schedule  2.22 or as may be disclosed in
the Forms 10-K and 10-Q of NMBT referred to in Section 2.02 hereof:

              (1) To NMBT's  actual  knowledge,  and except in  compliance  with
applicable  law, no Hazardous  Substances  (as  hereinafter  defined)  have been
stored, treated, dumped, spilled,  disposed,  discharged,  released or deposited
at, under or on (1) any property now owned, occupied,  leased or held or managed
in a representative or fiduciary capacity ("Present Property") by NMBT or any of
its subsidiaries, (2) any property previously owned, occupied, leased or held or
managed in a representative or fiduciary capacity ("Former Property") by NMBT or
any of its subsidiaries during the time of such previous  ownership,  occupancy,
lease;  holding or management or (3) any Participation  Facility (as hereinafter
defined)  during the time that NMBT or any of its  subsidiaries  participated in
the  management  of, or may be deemed to be or to have been an owner or operator
of, such Participation Facility;

              (2) Except in compliance with applicable law, neither NMBT nor any

                                  ARTICLE III.
                    REPRESENTATIONS AND WARRANTIES OF SUMMIT

       Summit represents and warrants to NMBT 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 177,061,084 shares were issued and outstanding as of August 1, 1999

                                       A-22

<PAGE>



and (ii) 6,000,000 shares of Preferred  Stock,  each without par value, of which
no shares are issued and outstanding and 1,500,000  shares of Series R Preferred
Stock are reserved for issuance as of the date hereof

       (b) Summit is qualified to transact  business in and is in good  standing
under the laws of all  jurisdictions  where the failure to be so qualified could
reasonably  be expected to have a material  adverse  effect on (i) the business,
results  of  operations,  assets  or  financial  condition  of  Summit  and  its
subsidiaries  on a consolidated  basis, or (ii) the ability of Summit to perform
its obligations under, and to consummate the transactions  contemplated by, this
Agreement (a "Summit  Material  Adverse  Effect").  However,  a Summit  Material
Adverse  Effect or Summit  Material  Adverse Change (as defined at Section 3.03)
will not  include a change  resulting  from a change in law,  rule,  regulation,
generally accepted or regulatory  accounting principle or other matter affecting
financial  institutions or their holding companies  generally or from charges or
expenses  incident to the  Reorganization.  The bank  subsidiaries of Summit are
duly  organized,  validly  existing and in good standing under the laws of their
jurisdiction  of  organization.  Summit  and  its  bank  subsidiaries  have  all
corporate   power  and   authority  and  all  material   licenses,   franchises,
certificates,  permits and other governmental  authorizations  which are legally
required to own and lease their respective  properties,  occupy their respective
premises,  and to  engage  in their  respective  businesses  and  activities  as
presently  engaged in,  except where the failure of such would not have a Summit
Material  Adverse Effect.  Summit and its bank  subsidiaries  have each complied
with all applicable laws,  regulations and orders except where the failure to so
comply  would  not  have 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 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,  1993  Incentive  Stock and Option  Plan,  1999
Non-Executive  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, 1998,  (b) annual  report on Form 10-K  pursuant to the Exchange Act for the
fiscal year ended December 31, 1998 and (c) quarterly reports on Form 10-Q filed
pursuant to the  Exchange Act for the fiscal  quarters  ended March 31, 1999 and
June 30,

                                      A-23

respects as of their respective dates and each fairly presents (subject,  in the
case of unaudited  statements,  to recurring audit adjustments  normal in nature

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 six months ended June 30, 1999 (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

                                       A-24

<PAGE>



governmental  agency,  except as may be  disclosed in the Forms 10-K and 10-Q of
Summit  referred to in Section 3.02.  Neither Summit nor any bank  subsidiary of
Summit is a party to any agreement or memorandum of understanding  with, or is a
party to any  commitment  letter  to,  or has  submitted  a board  of  directors
resolution  or similar  undertaking  to, or is subject to any order or directive
by,  or is a  recipient  of  any  extraordinary  supervisory  letter  from,  any
governmental or regulatory  authority which restricts  materially the conduct of
its business,  or in any manner relates to its capital  adequacy,  its credit or
reserve  policies or its  management.  Neither Summit nor any bank subsidiary of
Summit, has been advised by any governmental or regulatory  authority that it is
contemplating  issuing or requesting (or is considering the  appropriateness  of
issuing or requesting) any of the foregoing. Summit and the bank subsidiaries of
Summit have resolved to the satisfaction of the applicable regulatory agency any
significant   deficiencies   cited  by  any  such  agency  in  its  most  recent
examinations of each aspect of Summit or such bank subsidiary's  business except
for examinations, if any, received within the 30 days prior to the date hereof.

       Section 3.05. Regulatory Filings. At the time of filing, all filings made
by  Summit  and its  subsidiaries  after  December  31,  1995  with  the SEC and
appropriate bank regulatory  authorities did not contain any untrue statement of
a  material  fact and did not omit to state any  material  fact  required  to be
stated herein or therein or necessary to make the statements contained herein or
therein,  in  light  of the  circumstances  under  which  they  were  made,  not
misleading.  To the extent such filings were  subject to the  Securities  Act or
Exchange Act, such filings complied in all material respects with the Securities
Act or Exchange Act, as  appropriate,  and all applicable  rules and regulations
thereunder  of the SEC.  Summit has since  December  31,  1995  timely  made all
filings required by the Securities Act and the Exchange Act, as appropriate, and
all applicable  rules and regulations  thereunder of the SEC or the Federal bank
regulatory agency having  securities  regulatory  jurisdiction,  as appropriate.
Each of the financial statements (including related notes and schedules thereto)
contained in or incorporated by reference into such filings are true and correct
in all material  respects as of their  respective dates and each fairly presents
(subject,  in the case of unaudited  statements,  to recurring audit adjustments
normal in nature and amount),  in accordance with generally accepted  accounting
principles,  the  consolidated  statements  of  condition,  income,  changes  in
stockholders'  equity  and cash  flows of  Summit  and its  subsidiaries  at its
respective date and for the period to which it relates,  except as may otherwise
be  described  therein and except that in the case of unaudited  statements,  no
consolidated statements of changes in stockholders equity is included.

       Section 3.06.       Corporate Action.

       (a) Assuming due execution and delivery by NMBT, Summit has the corporate
power and is duly  authorized  by all  necessary  corporate  action to  execute,

all action required by law or by the Restated  Certificate of  Incorporation  or
By-Laws of Summit or otherwise to authorize  the  execution and delivery of this
Agreement.  Approval  by the  shareholders  of  Summit  of this  Agreement,  the
Reorganization  or  the  transactions  contemplated  by  this  Agreement  is not
required by  applicable  law.  Assuming  due  execution  and delivery by and the
enforceability  against NMBT of this  Agreement,  this  Agreement is a valid and
binding  agreement of Summit  enforceable in accordance with its terms except as
such  enforcement  may be limited by  applicable  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.

       (b) In the event that  pursuant  to the  Reorganization  Election  Summit
elects the Reorganization

                                       A-25

articles of  incorporation  and by-laws and otherwise to authorize the execution

transactions  contemplated  hereby  including the  Reorganization.  Assuming due
execution  and  delivery  by and the  enforceability  against  each of the other
parties  hereto,  this  Agreement  will be a valid and binding  agreement of the
Designated Summit Subsidiary  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.

       Section  3.07.  Absence of  Changes.  There has not been,  since June 30,
1999, 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 June 30, 1999 which are not

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
portfolios  of Summit  and its  subsidiaries  in excess of such  allowances  are
collectible in the ordinary course of business.

       Section 3.10. Accounting,  Tax and Regulatory Matters. Neither Summit nor
any of its  subsidiaries  has  taken or  agreed  to take any  action  or has any
knowledge of any fact or  circumstance  that would (i) prevent the  transactions

Section  368(a)  the Code,  or (ii)  materially  impede or delay  receipt of any
approval  referred to in Section 4.01 or the  consummation  of the  transactions

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

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

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

                                COVENANTS OF NMBT

       NMBT hereby covenants and agrees with Summit that:

       Section 4.01.  Preparation of Registration Statement and Applications for
Required  Consents.  NMBT 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 NMBT to solicit  shareholders of NMBT
for approval of the Reorganization.  In connection therewith,  NMBT will furnish
all  financial  or other  information,  including  using best  efforts to obtain
customary consents, certificates, opinions of counsel and other items concerning
NMBT,  deemed  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).  NMBT will cooperate with Summit and
provide  such  information  as  may  be  advisable  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 NMBT and its counsel a reasonable
opportunity to comment on such filings and regulatory applications and will give
due consideration to any comments of NMBT and its counsel before making any such
filing or application,  and Summit will provide NMBT 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. NMBT covenants and
agrees that all information  furnished by NMBT 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 by NMBT to Summit pursuant to this Agreement or
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.  NMBT will furnish to Advest such information  about NMBT reasonably
available to it as Advest may reasonably request for purposes

                                       A-27

of the opinion referred to in Section 8.07.

       Section 4.02. Notice of Adverse Changes. NMBT 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 NMBT  contained  in this
Agreement  or the NMBT  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 NMBT Material  Adverse Change,  (c) any inability or perceived
inability  of NMBT 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 NMBT or any of its subsidiaries or assets,
which, if determined adversely to NMBT or any of its subsidiaries,  would have a
NMBT 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 NMBT or a subsidiary  subsequent to the date hereof and prior to the
Effective Time, under any agreement,  indenture or instrument to which NMBT or a
subsidiary  is a party or is  subject  and which is  material  to the  business,
operation or condition  (financial or otherwise) of NMBT 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.  NMBT  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.  NMBT 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  shareholders
contemplated  by this Section 4.03 will be held as promptly as practicable  and,
in connection therewith,  will comply with the Delaware Law and the Exchange Act
and all regulations  promulgated  thereunder governing  shareholder meetings and
proxy  solicitations.  In  connection  with such  meeting,  NMBT  shall mail the
Proxy-Prospectus  to NMBT  shareholders  and  use its  best  efforts  to  obtain
shareholder approval of this Agreement,  the Reorganization and the transactions
contemplated  hereby;  provided,  however,  that no  director  of NMBT  shall be
obligated to take an action under this Section 4.03 in such person's capacity as
a  director  if such  person has been  advised  in writing by counsel  that such
action is contrary to the fiduciary duty owed as a director.

       Section  4.04.  Copies of Filings.  Without  limiting the  provisions  of
Section  4.01,  NMBT  will  deliver  to  Summit,  at least 48 hours  prior to an
anticipated date of filing or distribution or as soon thereafter as practicable,
all documents to be filed with the SEC or any bank regulatory authority or to be
distributed in any manner to the shareholders of NMBT or to the news media or to
the  public,  other than the press  releases  and other  information  subject to
Section 10.01.

will not and will not  allow  any of its  subsidiaries  to,  without  the  prior
written consent of Summit:

accounting  method,  and  approved  in writing by NMBT's  independent  certified
public accountants.

Summit and to its representatives,  including its accountants, KPMG Peat Marwick
LLP, and its legal counsel,  full access during normal  business hours to all of

the  Reorganization,  will provide such information with respect to its business
affairs and properties as Summit from time to time may reasonably  request,  and

reasonable request to answer questions of Summit's  representatives covering the
business and affairs of NMBT or any of its subsidiaries.

       Section 4.09.  Copies of Documents.  As promptly as practicable,  but not
later than 30 days after the date hereof, NMBT will furnish to or make available
to  Summit  all the  documents,  contracts,  agreements,  papers,  and  writings

       Section 4.10.  Applicable Laws. NMBT and its subsidiaries  will use their
best efforts to comply promptly with all requirements which federal or state law

connection with the Reorganization.

       Section  4.11.  Agreements  of  Affiliated  Shareholders.  NMBT agrees to
furnish to Summit,  not later than 10 business days prior to the date of mailing
of the  Proxy-Prospectus,  a writing  setting  forth the names of those  persons
(which will include all  individual  and  beneficial  ownership of NMBT Stock by
such persons and also identifies the manner in which all such beneficially owned
shares of NMBT Stock are  registered  on the stock  record books of NMBT) who in
the written  opinion of counsel to NMBT (which  opinion need not be furnished to
Summit),  constitute  all the  affiliates  of NMBT for the  purposes of Rule 145
under the  Securities  Act (an "NMBT  Affiliate").  NMBT  agrees to use its best
efforts (i) to cause each NMBT  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

                                       A-31

<PAGE>



NMBT or a subsidiary  of NMBT, or (z)  substantially  in the form of Exhibit D-2
with  respect to  Affiliates  who are not  directors  or  officers  of NMBT or a
subsidiary  of  NMBT  (an  "Affiliate  Agreement"),  and  (ii) to  furnish  such
Affiliate  Agreements  to Summit no later than 5 business days prior to the date
of mailing of the Proxy-Prospectus.

       Section  4.12.  Loans and  Leases  to  Affiliates.  All loans and  leases
hereafter  made by  NMBT or any of its  subsidiaries  to any of its  present  or
former  directors or executive  officers or their respective  related  interests

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

       Section 4.13.  Confidentiality.  All  information  furnished by Summit to
NMBT or its  representatives  pursuant  hereto  shall  be  treated  as the  sole
property  of Summit  and, if the  Reorganization  shall not occur,  NMBT and its
representatives  shall return to Summit all of such written  information and all
documents,  notes,  summaries  or  other  materials  containing,  reflecting  or
referring  to,  or  derived  from,  such  information,   except  that  any  such
confidential  information or notes or abstracts therefrom presented to the Board
of Directors  of NMBT or any  committee  thereof for the purpose of  considering
this Agreement,  the Reorganization and the related transactions may be kept and
maintained by NMBT with other records of Board,  and Board  committee,  meetings
subject to a continuing obligation of confidentiality. NMBT shall, and shall use
its best efforts to cause its  representatives  to, keep  confidential  all such
information,  and shall not directly or indirectly use such  information for any
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 NMBT's  possession  prior to the disclosure  thereof by
Summit, (y) was then generally known to the public, or (z) was disclosed to NMBT
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,  NMBT 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,
NMBT may disclose  such  information  to such tribunal or  governmental  body or
agency without liability  hereunder and shall so notify Summit in advance to the
extent  practicable.  This Section 4.13 shall  survive any  termination  of this
Agreement.

       Section 4.14. Dividends. NMBT will coordinate with Summit the declaration
of any dividends and the record and payment dates thereof so that the holders of
NMBT Stock will not be paid two  dividends  for a single  calendar  quarter with
respect to their shares of NMBT 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. NMBT will
notify  Summit  at least  five  business  days  prior to any  proposed  dividend
declaration date.

       Section 4.15.  Acquisition  Proposals.  NMBT agrees that neither NMBT nor
any of its subsidiaries nor any of the respective officers and directors of NMBT
or its  subsidiaries  shall,  and NMBT 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 NMBT 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);

                                       A-32

<PAGE>



provided however, that the Board of Directors of NMBT may furnish or cause to be
furnished  nonpublic   information   directly  or  through  its  representatives
concerning an Acquisition  Proposal,  if such Board of Directors has determined,
after having consulted with outside counsel and been advised of its legal rights
to the effect,  that the failure to provide  such  nonpublic  information  would
cause the members of such Board of Directors to breach  their  fiduciary  duties
under applicable laws, and,  provided,  further,  that NMBT shall first obtain a
confidentiality  agreement  in  customary  form  and  containing  at  least  the
confidentiality  provisions  set forth at Sections  4.13 and 5.08.  "Acquisition
Proposal"  is hereby  defined to be any offer,  including  an exchange  offer or
tender offer, or proposal concerning a merger, consolidation,  or other business
combination or takeover transaction involving NMBT or any of its subsidiaries or
the  acquisition of any assets  (otherwise than as permitted by Section 4.05) or
securities of NMBT or any of its  subsidiaries.  NMBT 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. NMBT 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, NMBT 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 NMBT or any of its  subsidiaries  or assets by another
party,  and  will   immediately   deliver  as  soon  as  possible  by  facsimile
transmission,  receipt acknowledged,  to the Summit officer notified as required
above a copy of any document  relating  thereto promptly after any such document
is received by NMBT.

       Section 4.16 Tax Opinion Certificates.  NMBT shall execute and deliver to
Thompson  Coburn any tax  opinion  certificate  reasonably  required by Thompson
Coburn in  connection  with the  issuance  of the Tax  Opinions  (as  defined at
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 NMBT shall use its best efforts to cause
each of its  executive  officers,  directors and holders of five percent (5%) or
more of outstanding NMBT 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.  NMBT 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
known to NMBT.  NMBT shall renew any  existing  D&O  Insurance  or purchase  any
"discovery period" D&O Insurance provided for thereunder at Summit's request.

       Section 4.18.       Conforming Entries.

       (a)  Notwithstanding  that NMBT believes  that NMBT 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,  NMBT 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,  NMBT and Summit  shall  consult and  cooperate  with each other with
respect to  conforming  the loan,  accrual and reserve  policies of NMBT and its
subsidiaries to those policies of Summit, as specified in each case

                                       A-33

in writing to NMBT, based upon such consultation and as hereinafter provided.

       (b) In  addition,  from and  after the date of this  Agreement,  NMBT and
Summit shall consult and cooperate  with each other with respect to  determining
appropriate  accruals,  reserves and charges for NMBT 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 NMBT, based upon such consultation and as hereinafter provided.

       (c) NMBT and Summit  shall  consult  and  cooperate  with each other with
respect to determining  the amount and the timing for  recognizing for financial
accounting  purposes NMBT'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 NMBT and Summit that such  reserves,  accruals,  charges and
divestitures,  if any, to be taken shall be consistent  with generally  accepted
accounting principles, and (ii) NMBT shall not be obligated to make a particular
conforming entry (A) effecting financial  statements as at or for periods ending
December 31, 1999 or earlier,  or (B) 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 NMBT.

       Section 4.19 Cooperation with Policies and Procedures. NMBT, 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 NMBT's  existing  policies and  procedures in respect  thereof,
provided that NMBT shall not be required to conform a policy or procedure (y) if
such would cause NMBT or any of its  subsidiaries to be in violation of any law,
rule, regulation or requirement of any governmental  regulatory authority having
jurisdiction over NMBT 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 NMBT's
financial statements.

       Section 4.20  Environmental  Reports.  NMBT shall  disclose to Summit all
matters of the types described in Section 2.22 hereof which NMBT would have been
required  to  disclose to Summit on the date hereof if known to NMBT on the date
hereof,  as such become known to NMBT 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 NMBT or any of its subsidiaries as of the
date of this Agreement (but excluding space in retail or similar  establishments
leased by NMBT for automatic  teller  machines or leased bank branch  facilities
where the space leased by NMBT comprises less than 20% of the total space leased
to all tenants of such  property),  and (ii) within 15 days after being notified
by  NMBT  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
NMBT for automatic  teller machines or leased bank branch  facilities  where the
space  leased by NMBT  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 NMBT or Summit) indicate, in the reasonable opinion of Summit, that
additional investigation is warranted, Summit may at its expense,

                                       A-34

<PAGE>



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  NMBT 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 reasonably
recommended 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 $1,000,000,
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        [Reserved]

       Section 4.22.  Dividend  Equivalency.  In the event the number determined
pursuant  to  Section  1.03(c)  to be the  Exchange  Ratio is  greater  than the
multiplier set forth at Section  4.05(a),  shareholders of record of NMBT at the
Effective Time shall become entitled to receive a cash payment per share of NMBT
Stock  held by them at the  Effective  Time  equal in amount  to the  difference
between  (i) the  dividends  per share  NMBT  would be able to pay  pursuant  to
Section 4.05(a) if the multiplier stated therein were such number,  and (ii) the
dividends  per share  actually  paid by NMBT  pursuant to Section  4.05(a).  Any
payment which NMBT  shareholders may become entitled to receive pursuant to this
Section 4.22 shall be distributed by Summit simultaneously with the distribution
of the Reorganization Consideration provided for in Article I.

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

in writing of (a) any event  occurring  subsequent to the date of this Agreement

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 NMBT of any of the provisions of Articles VI or VIII.

       Section 5.03.  Copies of Filings.  Summit shall promptly  provide to NMBT
and its counsel copies of the application  filed with the Federal Reserve Board,

instruments and take such other actions as NMBT may reasonably  require to carry
out the  intent of this  Agreement;  (b) use all  reasonable  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 best efforts so that
the other conditions  precedent to the obligations of NMBT set forth in Articles

       Section 5.05. Applicable Laws. Summit will use its 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 NMBT in connection with any such  requirements  imposed upon NMBT
or on any of its subsidiaries in connection with the Reorganization.

       Section 5.06. Unpaid NMBT Dividends.  By virtue of the Reorganization and
without  further action on anyone's part,  Summit shall assume the obligation of
NMBT to pay  dividends,  if any, on NMBT 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

                                       A-36

<PAGE>



with respect to its business  affairs and  properties  as NMBT 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 NMBT's representatives  covering the business and affairs
of Summit or any of its subsidiaries.

       Section  5.08.  Confidentiality.  All  information  furnished  by NMBT to
Summit or its  representatives  pursuant  hereto  shall be  treated  as the sole
property  of NMBT and,  if the  Reorganization  shall not occur,  Summit and its
representatives  shall  return to NMBT 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 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  NMBT,  (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   NMBT  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 NMBT
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 NMBT or any  subsidiary of NMBT 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 NMBT or
the  applicable  subsidiary  of  NMBT,  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

                                       A-37

<PAGE>



Certificate of Incorporation and By-Laws in effect on the date of this Agreement
and any applicable provisions of law.

       (b) Subject to NMBT's  obligation set forth at Section 4.17: For a period
of six (6) years after the Effective  Time,  Summit will use its best efforts to
provide  to the  persons  who served as  directors  or  officers  of NMBT or any
subsidiary of NMBT 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 NMBT on an annual  basis (the
"Insurance  Amount") to maintain or procure insurance  coverage pursuant hereto,
and,  further  provided,  that if Summit is unable  to  maintain  or obtain  the
insurance called for by this Section 5.10,  Summit shall use its best efforts to
obtain as much comparable insurance as is available for the Insurance Amount.

       (c) This  Section 5.10 shall be construed as an agreement as to which the
directors  and  officers  of NMBT 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.

       Section 5.11.       Employee Matters.

       (a) After the  Effective  Time,  Summit may in its  discretion  maintain,
terminate,  merge or  dispose of the NMBT  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 NMBT Plan which is,  respectively,  a
defined  contribution  plan,  defined  benefit  plan or health and welfare  plan
available to all NMBT employees generally, then, if such NMBT Plan is terminated
by Summit or is otherwise rendered inactive by Summit, Summit shall offer to the
former  employees  of NMBT  affected by such plan  termination  or  cessation of
activity the opportunity to participate in the similar plan of Summit.

       (b) Summit assumes all obligations under deferred  compensation  plans of
NMBT but shall have the right to terminate  such plans  following  the Effective
Time with respect to future compensation deferrals.

       (c) Summit agrees that the severance  plan of NMBT shall remain in effect
following the Effective Time  notwithstanding the provisions of Section 5.11 and
shall apply according to its terms to persons  employed by NMBT at the Effective
Time.

       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).

       Section 5.13.  Additional  Tax Opinion.  NMBT shall be entitled to seek a
tax opinion  satisfactory  to it in form and content  from legal  counsel of its
choice in addition to the Tax Opinion, but receipt of such tax opinion shall not
be a  condition  to  NMBT's  closing  of  the  Reorganization  or to  any  other
obligation of NMBT hereunder.

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 NMBT in
accordance with Section 10.09:

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

       Section  6.02.  Effective   Registration   Statement.   The  Registration
Statement  shall  have  been  declared  effective  by the  SEC;  no  stop  order
suspending  the  effectiveness  of the  Registration  Statement  shall have been
issued and remain in effect;  and no proceeding for that purpose shall have been
initiated  or, to the  knowledge  of Summit or NMBT,  shall be  contemplated  or
threatened by the SEC.

       Section  6.03.  Tax  Matters.   At  the  time  of  effectiveness  of  the
Registration  Statement  and at the  Closing  Date (and at the date the  Closing
occurs if different than the Closing Date),  Summit and NMBT shall have received

include the holding period of the NMBT Stock for which it is exchanged, assuming
that such NMBT 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.

       Section 6.04.  Absence of Litigation.  No  investigation  by any state or
federal agency, and no action, suit, arbitration or proceeding before any court,
state or federal agency,  panel or governmental or regulatory body or authority,

Reorganization or to the financial condition of Summit and its subsidiaries on a
consolidated basis or NMBT and its subsidiaries on a consolidated  basis, as the
case may be. No order, decree,  judgment,  or regulation shall have been entered
or law or regulation adopted by any such agency,  panel, body or authority which

warranties  made by  NMBT in this  Agreement  and  the  NMBT  Schedules  and the

<PAGE>

satisfied,  and (ii) the Board of Directors of such party may, during the period

failed to satisfy a condition to the other party's  Closing  obligation or is in
Material Breach.

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

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

              (2)  at any  time  prior  to  the  meeting  of  NMBT  shareholders

transactions  contemplated hereby in the Proxy-Prospectus  ("Recommendation") or
withdraws,  modifies or changes,  or votes to  withdraw,  modify or change,  its
Recommendation  or its intention to make the  Recommendation  as represented and

                                                                JANUARY 28, 2000


Board of Directors
NMBT Corp
55 Main Street
New Milford, Connecticut 06776

Members of the Board:

           NMBT Corp ("NMBT") and Summit Bancorp ("Summit") have entered into an
Agreement and Plan of Merger dated October 3, 1999 (the  "Agreement"),  pursuant
to which NMBT will merge with Summit in a manner as described in the  Agreement.
The Agreement  provides that each outstanding  share of NMBT common stock issued
and  outstanding  at the Effective  Time (as defined in the  Agreement)  will be
converted  into the right to receive whole shares of Summit Stock (as defined in
the Agreement) and cash in lieu of fractional  shares of Summit Stock based upon
the Exchange Ratio determined as follows:

           (i)  if the Summit Price (as defined in the Agreement) is greater
                than $37.0156, the Exchange Ratio shall be .7024;

           (ii) if the Summit Price is equal to or greater than $27.3594 and
                equal to or less than $37.0156, the Exchange Ratio shall be
                equal to the quotient obtained by dividing $26.00 by the Summit
                Price; and

          (iii) if the Summit Price is less than $27.3594, the Exchange Ratio
                shall be .9503.

           The terms and conditions of the proposed transaction are described in
further detail in the  Agreement.  The Agreement is expected to be considered by
the  shareholders of NMBT at a shareholders  meeting and the Merger  consummated
shortly  after  the  receipt  of  shareholder,   state  and  federal  regulatory
approvals.

           You have asked us whether,  in our  opinion,  the  Exchange  Ratio is
fair, from a financial point of view, to the shareholders of NMBT.


           In  arriving at the opinion  set forth  below,  we have,  among other
things:  reviewed  the  Agreement  dated  October 3, 1999,  and the exhibits and
schedules  thereto;  reviewed the Stock Option  Agreement  dated October 4, 1999
between NMBT and Summit;  reviewed the Annual  Reports on Form 10-K for NMBT and
Summit for the years ended December 31, 1998, 1997, and 1996;  reviewed the year
end  December  31, 1999  earnings  releases  for NMBT and Summit;  reviewed  the
Quarterly  Reports  on Form  10-Q for  NMBT and  Summit  for the  periods  ended
September 30, 1999, June 30, 1999 and March 31, 1999; reviewed certain financial
analyses  and  forecasts  of NMBT which were  prepared  by  management  of NMBT;
reviewed  comparative  financial and operating data on the banking  industry and
certain  institutions  which  we  deemed  to be  comparable  to each of NMBT and
Summit;  reviewed  the  historical  market  prices and trading  activity for the
common  stock of each of NMBT and  Summit  relative  to  other  publicly  traded
companies  which we  deemed  to be  comparable  to each  company;  reviewed  the
contribution of NMBT and Summit to the new proforma combined entity on the basis
of a number of key  financial  categories  in relation  to  proforma  ownership;
reviewed the proforma impact of the merger; reviewed the present value of NMBT's
business plan;  reviewed certain bank mergers and acquisitions on a regional and
nationwide basis for  institutions  which we deemed to be comparable to NMBT and
compared the proposed  consideration  with the consideration  paid in such other
mergers  and  acquisitions;  considered  the  financial  effect  of  the  Summit
equivalent  dividends to be paid by NMBT to its  shareholders  during the period
beginning  from the  date of the  Agreement  to the  Effective  Time;  conducted
limited discussions with members of senior management of each of NMBT and Summit
concerning the financial  condition,  business and prospects of each  respective
company;  and reviewed such other  financial  studies and analyses and performed
such other  investigations and took into account such other matters as we deemed
necessary.


           In performing our review and preparing this opinion,  we have assumed
and  relied  upon the  accuracy  and  completeness  of all  financial  and other
information  reviewed  by us for  purposes  of this  opinion,  and we  have  not
independently  verified such  information  nor have we undertaken an independent
evaluation  of the assets  and  liabilities  of NMBT or Summit.  Advest has been
retained by the Board of Directors  of NMBT to act as financial  advisor to NMBT
with respect to the Merger and will  receive a fee for its services  including a
fee for  this  opinion.  In the  past  we  have  also  performed  certain  other
investment  banking  services for NMBT and have received  compensation  for such
services.


                                       B-1

           This opinion is necessarily  based upon  circumstances and conditions
as they  exist and can be  evaluated  by us as of the date of this  letter.  Our
opinion is directed to the Board of Directors of NMBT and does not  constitute a
recommendation of any kind to any shareholder of NMBT as to how such shareholder
should  vote at the  shareholders'  meeting  to be held in  connection  with the
merger.  We have  assumed for  purposes of this  opinion  that there has been no
material  change in the  financial  condition of either NMBT or Summit from that
reflected in the Form 10-Q for the quarter and nine months ended  September  30,
1999 filed with the  Securities  and  Exchange  Commission  for each  respective
company.


           In  reliance  upon and  subject to the  foregoing,  it is our opinion
that, as of the date hereof,  the Exchange Ratio is fair, from a financial point
of view, to the shareholders of NMBT.

           Advest will consent to a description and inclusion of this opinion in
documents  issued with regard to this transaction and to references to Advest in
such documents, provided that any such description and references are reasonably
acceptable to Advest. Except as otherwise provided above, this opinion is solely
for the use and benefit of the Company  and shall not be  disclosed  publicly or
made  available to third  parties  without the prior  approval of Advest,  which
approval shall not be unreasonably withheld.

                                               Very truly yours,

                                               Advest, Inc.

                        NMBT CORP STOCK OPTION AGREEMENT

THE  TRANSFER  OF THE  OPTION  GRANTED  BY THIS  AGREEMENT  IS SUBJECT TO RESALE
RESTRICTIONS ARISING UNDER THE SECURITIES ACT OF 1933, AS AMENDED.

         STOCK OPTION AGREEMENT,  dated as of the 4th day of October, 1999 (this
"Agreement"), between Summit Bancorp., a New Jersey corporation ("Grantee"), and
NMBT CORP, a Delaware corporation ("Issuer").

                                   WITNESSETH:

         WHEREAS,  Grantee and Issuer  have on a date prior to the date  hereof,
entered  into an  Agreement  and  Plan  of  Merger,  dated  as of the 3rd day of
October,  1999  (the  "Merger  Agreement").  (Capitalized  terms  used  in  this
Agreement and not defined herein but defined in the Merger  Agreement shall have
the meanings assigned thereto in the Merger Agreement); and

         WHEREAS,  as a condition and inducement to Grantee's  entering into the
Merger Agreement and in consideration therefor, Grantee has required that Issuer
agree, and Issuer has agreed, to grant Grantee the Option (as defined below);

         NOW,  THEREFORE,  in  consideration  of the  foregoing  and the  mutual
covenants  and  agreements  set forth  herein and in the Merger  Agreement,  the
parties hereto agree as follows:

         SECTION  1.  Grant of  Option.  Issuer  hereby  grants  to  Grantee  an
unconditional,  irrevocable  option (the  "Option") to purchase,  subject to the
terms hereof,  up to 531,043 fully paid and  nonassessable  shares of the common
stock,  par value $.01 per share, of Issuer ("Common Stock") at a price equal to
$18.87 (such price, as adjusted as hereinafter  provided,  the "Option  Price").
The number of shares of Common  Stock that may be received  upon the exercise of
the Option and the Option Price are subject to  adjustment  as herein set forth.
In no event shall the number of shares of Common  Stock for which this Option is
exercisable exceed 19.9% of the number of shares of Common Stock then issued and
outstanding  (without  consideration of any shares of Common Stock subject to or
issued pursuant to the Option).

         SECTION 2. Exercise of Option.  (a) Grantee may exercise the Option, in
whole or part, at any time and from time to time  following the  occurrence of a
Purchase Event (as defined below);  provided that the Option shall terminate and
be of no further  force and effect  upon the  earliest  to occur of (i) the time
immediately  prior to the  Effective  Time,  (ii) a  termination  of the  Merger
Agreement in accordance  with the terms  thereof  prior to the  occurrence of an
Extension Event, other than a termination of the Merger Agreement by the Grantee
pursuant to Section  9.02(a)(2),  Section 9.02(c) or Section 9.02(d)(2) thereof,
or (iii) 12 months after a  termination  of the Merger  Agreement  following the
occurrence of an Extension  Event (as defined  below) or after a termination  of
the Merger Agreement by Grantee pursuant to Section 9.02(a)(2),  Section 9.02(c)
or Section 9.02(d)(2) thereof, and provided further, that any purchase of Common
Stock upon  exercise  of the Option  shall be subject  to  applicable  law,  and
provided further, that the Option may not be exercised,  nor may Grantee require
Issuer to repurchase  the Option (as set forth in Section 7 hereof),  if, at the
time of exercise or  repurchase,  Grantee is in material  breach of any material
covenant or  obligation  contained  in the Merger  Agreement  and, if the Merger
Agreement has not terminated prior thereto,  such breach would entitle Issuer to
terminate the Merger  Agreement.  The events described in clauses (i) - (iii) in
the  preceding  sentence are  hereinafter  collectively  referred to as Exercise
Termination Events. As provided in Section 8, the rights set forth therein shall
terminate upon an Exercise  Termination Event and, as provided in Sections 6 and
7 hereof,  the  rights to deliver  requests  pursuant  to  Sections 6 or 7 shall
terminate 12 months after an Exercise Termination Event,  subject, in such case,
to the provisions of Section 9.

         (b) The term "Extension  Event" shall mean any of the following  events
or transactions  occurring without the Grantee's prior written consent after the
date hereof:

                  (i)  Issuer  or any  of  its  subsidiaries  (each  an  "Issuer
Subsidiary"),  shall have entered into an agreement to engage in an  Acquisition
Transaction  (as defined  below) with any person (the term "person" for purposes
of this Agreement  having the meaning  assigned  thereto in Sections 3(a)(9) and
13(d)(3) of the  Securities  Exchange Act of 1934,  as amended (the  "Securities
Exchange Act"), and the rules and regulations  thereunder) other than Grantee or
any of its subsidiaries (each a "Grantee  Subsidiary") or the Board of Directors
of Issuer shall have  recommended  that the  shareholders  of Issuer  approve or
accept any  Acquisition  Transaction  with any person  other than Grantee or any
Grantee

                                      C-1
<PAGE>



Subsidiary. For purposes of this Agreement, "Acquisition Transaction" shall mean
(w) a merger or consolidation,  or any similar transaction,  involving Issuer or
any of Issuer's  banking  subsidiaries  ("Bank  Subsidiaries"),  (x) a purchase,
lease or other  acquisition of 10% or more of the aggregate  value of the assets
or  deposits  of  Issuer  or  any  Bank  Subsidiary,  (y) a  purchase  or  other
acquisition  (including  by way of  merger,  consolidation,  share  exchange  or
otherwise) of securities  representing 10% or more of the voting power of Issuer
or a Bank Subsidiary,  or (z) any substantially  similar transaction,  provided,
however,  that in no  event  shall  (i) any  merger,  consolidation  or  similar
transaction  involving  Issuer  or any  Bank  Subsidiary  in  which  the  voting
securities of Issuer outstanding immediately prior thereto continue to represent
(either by remaining  outstanding or being  converted into voting  securities of
the  surviving  entity of any such  transaction)  at least  75% of the  combined
voting  power of the voting  securities  of the Issuer or the  surviving  entity
outstanding  after the  consummation of such merger,  consolidation,  or similar
transaction,  or (ii) any internal merger or consolidation involving only Issuer

that any such  transaction  is not entered into in violation of the terms of the
Merger Agreement;

                  (ii) Any person (other than Grantee or any Grantee Subsidiary)
shall have  acquired  beneficial  ownership  or the right to acquire  beneficial
ownership of securities  representing  10% or more of the aggregate voting power
of Issuer or any Bank Subsidiary (the term  "beneficial  ownership" for purposes
of this Agreement  having the meaning  assigned  thereto in Section 13(d) of the
Securities Exchange Act, and the rules and regulations thereunder);

                  (iii) Any person other than Grantee or any Grantee  Subsidiary
shall have made a bona fide  proposal to Issuer or its  shareholders,  by public
announcement or written  communication  that is or becomes the subject of public
disclosure,  to  engage  in  an  Acquisition  Transaction  (including,   without
limitation,  any situation in which any person other than Grantee or any Grantee
Subsidiary shall have commenced (as such term is defined in Rule 14d-2 under the
Exchange Act), or shall have filed a registration statement under the Securities
Act of 1933, as amended (the "Securities  Act"), with respect to, a tender offer
or  exchange  offer to  purchase  any shares of Common  Stock  such  that,  upon
consummation  of  such  offer,  such  person  would  own or  control  securities
representing  10% or more of the  aggregate  voting  power of Issuer or any Bank
Subsidiary);

                  (iv)  After any  person  other  than  Grantee  or any  Grantee
Subsidiary  has made or  disclosed  an intention to make a proposal to Issuer or
its  shareholders  to engage in an  Acquisition  Transaction,  Issuer shall have
breached any covenant or obligation  contained in the Merger  Agreement and such
breach (x) would entitle Grantee to terminate the Merger Agreement and (y) shall
not have been cured prior to the Notice Date (as defined below);

                  (v) Any person  other than  Grantee or any Grantee  Subsidiary
shall have filed an application  with, or given a notice to, whether in draft or
final form,  the Board of Governors of the Federal  Reserve System (the "Federal
Reserve Board") or other governmental  authority or regulatory or administrative
agency or commission,  domestic or foreign (each, a  "Governmental  Authority"),
for approval to engage in an Acquisition Transaction;

                  (vi) A meeting of  shareholders  shall not have been called by
the Board of Directors of Issuer in  accordance  with Section 4.03 of the Merger
Agreement or held or shall have been  canceled,  or Issuer's  Board of Directors
shall have withdrawn or modified in a manner adverse to the  consummation of the
Merger  its  unanimous  recommendation  of the  Merger  or made an  announcement
prospectively with respect to such a withdrawal or modification; or

                  (vii) any Purchase Event (as defined below), other than events
described at Section 2(c)(iii).

         (c) The term "Purchase Event" shall mean either of the following events
or transactions occurring after the date hereof:

                  (i) The  acquisition  by any person  other than Grantee or any
Grantee  Subsidiary of beneficial  ownership of securities  representing  25% or
more of the aggregate voting power of Issuer or any Bank Subsidiary;

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

                                       C-2

<PAGE>



                  (iii) the holders of Common Stock shall not have  approved the
Merger  Agreement  at the meeting of such  shareholders  held for the purpose of
voting on the Merger  Agreement,  such meeting shall not have been called by the
Board of  Directors  of Issuer in  accordance  with  Section  4.03 of the Merger
Agreement or held or shall have been  canceled,  or Issuer's  Board of Directors
shall have withdrawn or modified in a manner adverse to the  consummation of the
Merger  its  unanimous  recommendation  of the  Merger  or made an  announcement
prospectively  with respect to such a withdrawal or  modification;  in each case
after an Extension Event other than any event described at Section 2 (b)(vi)

         (d) Issuer shall notify  Grantee  promptly in writing of the occurrence
of any Extension Event or Purchase Event;  provided however,  that the giving of
such  notice  by Issuer  shall not be a  condition  to the right of  Grantee  to
exercise the Option.

         (e) In the event that Grantee is entitled to and wishes to exercise the
Option, it shall send to Issuer a written notice (the date of which being herein
referred to as the "Notice  Date")  specifying (i) the total number of shares of
Common Stock it will purchase  pursuant to such exercise,  (ii) a place and date
not earlier than three  business  days nor later than 90 business  days from the
Notice Date for the closing of such purchase (the "Closing Date") and (iii) that
the  proposed  exercise of the Option shall be revocable by Grantee in the event
that the  transaction  constituting  a  Purchase  Event  that gives rise to such
written notice shall not have been consummated  prior to exercise of the Option;
provided that if prior  notification to or approval of the Federal Reserve Board
or any  other  Governmental  Authority  is  required  in  connection  with  such
purchase,  Grantee shall promptly file the required  notice or  application  for
approval  and shall  expeditiously  process the same and the period of time that
otherwise  would run pursuant to this  sentence  shall run from the later of (x)
the date on  which  any  required  notification  periods  have  expired  or been
terminated  and (y) the date on which such  approvals have been obtained and any
requisite waiting period or periods shall have expired.  For purposes of Section
2(a),  any  exercise  of the Option  shall be deemed to occur on the Notice Date
relating  thereto.  Grantee shall have the right to revoke its proposed exercise
of the Option in the event that the  transaction  constituting  a Purchase Event
that gives rise to such right to exercise shall not have been consummated  prior
to  exercise  of the  Option,  pursuant  to the  statement  of such right in the
written notice exercising the Option as provided in clause 2(e)(iii) above.

         (f) At the closing referred to in Section 2(e), Grantee shall surrender
this Agreement  (and the Option granted  hereby) to Issuer and pay to Issuer the
aggregate Option Price for the shares of Common Stock purchased  pursuant to the
exercise of the Option in immediately available funds by wire transfer to a bank
account  designated  by Issuer;  provided,  however,  that failure or refusal of
Issuer  to  designate  such a bank  account  shall  not  preclude  Grantee  from
exercising the Option.

         (g) At such closing,  simultaneously with the delivery of the aggregate
Option Price in immediately  available funds as provided in Section 2(f), Issuer
shall deliver to Grantee a certificate or certificates  representing  the number
of shares of Common  Stock  purchased  by Grantee  and, if the Option  should be
exercised in part only, a new Option Agreement  granting a new Option evidencing
the rights of Grantee  thereof to  purchase  the balance of the shares of Common
Stock purchasable hereunder.

         (h)  Certificates  for Common Stock  delivered  at a closing  hereunder
shall be endorsed with a restrictive legend substantially as follows:

         "The transfer of the shares  represented by this certificate is subject
         to resale  restrictions  arising under the  Securities  Act of 1933, as
         amended,  and to certain  provisions  of an  agreement  between  Summit
         Bancorp.  and NMBT CORP ("Issuer")  dated as of the 4th day of October,
         1999. A copy of such  agreement is on file at the  principal  office of
         Issuer and will be provided to the holder  hereof  without  charge upon
         receipt by Issuer of a written request therefor."

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

                                       C-3

<PAGE>



if the conditions in the preceding  clauses (i) and (ii) are both satisfied.  In
addition,  such  certificates  shall bear any other legend as may be required by
law.

         (i) Upon the  giving by  Grantee  to Issuer  of the  written  notice of
exercise  of the  Option  provided  for in  Section  2(e) and the  tender of the
aggregate  Option  Price on the Closing  Date in  immediately  available  funds,
Grantee shall be deemed to be the holder of record of the shares of Common Stock
issuable upon such  exercise,  notwithstanding  that the stock transfer books of
Issuer  shall then be closed or that  certificates  representing  such shares of
Common Stock shall not then  actually be delivered to Grantee.  Issuer shall pay
all expenses and any and all United  States  federal,  state and local taxes and
other charges that may be payable in connection with the preparation,  issue and
delivery of stock  certificates  under this  Section 2 in the name of Grantee or
its nominee.

         SECTION 3. Reservation of Shares.  Issuer agrees:  (i) that it shall at
all times until the  termination  of this  Agreement  have reserved for issuance
upon the exercise of the Option that number of authorized shares of Common Stock
equal to the maximum  number of shares of Common Stock at any time and from time
to time issuable  hereunder,  all of which shares will,  upon issuance  pursuant
hereto,  be duly  authorized,  validly issued,  fully paid,  nonassessable,  and
delivered  free and  clear  of all  claims,  liens,  encumbrances  and  security
interests and not subject to any  preemptive  rights;  (ii) that it will not, by
amendment  of  its   certificate  or  articles  of   incorporation   or  through
reorganization,  consolidation, merger, dissolution or sale of assets, or by any
other voluntary act, avoid or seek to avoid the observance or performance of any
of the  covenants,  stipulations  or  conditions  to be  observed  or  performed
hereunder by Issuer;  (iii) promptly to take all action as may from time to time
be required (including (x) complying with all premerger notification,  reporting
and waiting period  requirements  specified in 15 U.S.C. ss. 18a and regulations
promulgated  thereunder and (y) in the event, under the Bank Holding Company Act
of 1956, as amended (the "BHC Act"),  or the Change in Bank Control Act of 1978,
as amended, or any state banking law, prior approval of or notice to the Federal
Reserve  Board or to any other  Governmental  Authority is necessary  before the
Option may be exercised, cooperating with Grantee in preparing such applications
or notices and providing such  information to the Federal Reserve Board and each
other Governmental  Authority as they may require) in order to permit Grantee to
exercise  the Option and Issuer duly and  effectively  to issue shares of Common
Stock pursuant  hereto;  and (iv) to take all action  provided herein to protect
the rights of Grantee against dilution.

         SECTION 4. Division of Option.  This  Agreement (and the Option granted
hereby)  are  exchangeable,  without  expense,  at the option of  Grantee,  upon
presentation  and surrender of this Agreement at the principal office of Issuer,
for other agreements providing for Options of different  denominations entitling
the  holder  thereof  to  purchase,  on the same  terms and  subject to the same
conditions as are set forth  herein,  in the aggregate the same number of shares
of Common Stock  purchasable  hereunder.  The terms  "Agreement" and "Option" as
used herein include any agreements and related  options for which this Agreement
(and the Option  granted  hereby) may be  exchanged.  Upon  receipt by Issuer of
evidence  reasonably  satisfactory  to it of the  loss,  theft,  destruction  or
mutilation of this Agreement, and (in the case of loss, theft or destruction) of
reasonably satisfactory indemnification,  and upon surrender and cancellation of
this Agreement, if mutilated, Issuer will execute and deliver a new Agreement of
like  tenor  and date.  Any such new  Agreement  executed  and  delivered  shall
constitute an additional  contractual  obligation on the part of Issuer, whether
or not the Agreement so lost,  stolen,  destroyed or mutilated shall at any time
be enforceable by anyone.

         SECTION 5.  Adjustment  upon  Change of  Capitalization.  The number of
shares of Common  Stock  purchasable  upon the  exercise of the Option  shall be
subject to adjustment from time to time as follows:

         (a)  Subject  to the last  sentence  of  Section 1, in the event of any
change in the Common  Stock by reason of stock  dividends,  split-ups,  mergers,
recapitalizations,  combinations, subdivisions, conversions, exchanges of shares
or the like,  the type and  number of shares of Common  Stock  purchasable  upon
exercise hereof shall be  appropriately  adjusted and proper  provision shall be
made so that, in the event that any additional  shares of Common Stock are to be
issued or otherwise to become  outstanding as a result of any such change (other
than  pursuant  to an exercise  of the  Option),  the number of shares of Common
Stock that remain  subject to the Option shall be increased so that,  after such
issuance and together with shares of Common Stock previously  issued pursuant to
the  exercise  of the Option  (as  adjusted  on account of any of the  foregoing
changes in the Common Stock),  it equals 19.9% of the number of shares of Common
Stock then issued and outstanding (without consideration of any shares of Common
Stock subject to or issued pursuant to the Option).

         (b)  Whenever  the number of shares of Common  Stock  purchasable  upon
exercise  hereof is adjusted as  provided  in this  Section 5, the Option  Price
shall be adjusted by multiplying the Option Price by a fraction, the numerator

                                       C-4

<PAGE>



of which  shall be equal to the  number of shares  of Common  Stock  purchasable
prior to the  adjustment  and the  denominator  of  which  shall be equal to the
number of shares of Common Stock purchasable  after the adjustment.  In no event
shall the  Option  Price be  adjusted  to less than the par value of the  Common
Stock to be issued at such Option Price.

         (c) It is intended by the parties hereto that the adjustments  provided
by this Section 5 shall fully  preserve the economic  benefits of this Agreement
for Grantee.

         SECTION 6.        Registration Rights.

         (a) Demand  Registration  Rights.  After the  occurrence  of a Purchase
Event that occurs prior to an Exercise  Termination Event,  Issuer shall, at the
request of  Grantee  (whether  on its own behalf or on behalf of any  subsequent
holder  of  the  Option  (or  part  thereof)  delivered  prior  to  an  Exercise
Termination  Event or at the  request of a holder of any of the shares of Common
Stock  issued  pursuant  hereto)  delivered  no later  than 12  months  after an
Exercise  Termination  Event,   promptly  prepare,   file  and  keep  current  a
registration  statement on such form as is available  and the Issuer is eligible
to use under the Securities Act relating to a delayed or continuous offering (as
contemplated  by Rule 415 of the SEC under the  Securities  Act or any successor
rule or regulation) (a "shelf registration") covering this Option and any shares
issued and issuable  pursuant to the Option (the "Option  Shares") and shall use
its best efforts to cause such  registration  statement to become  effective and
remain  current and to qualify  this  Option or any such Option  Shares or other
securities  for sale  under any  applicable  state  securities  laws in order to
permit the sale or other  disposition  of this  Option or any  Option  Shares in
accordance with any plan of disposition requested by Grantee; provided, however,
that  Issuer  may  postpone  filing  a  registration  statement  relating  to  a
registration  request by Grantee  under this Section 6 for a period of time (not
in  excess  of 90  days)  if in its  judgment  such  filing  would  require  the
disclosure of material  information that Issuer has a bona fide business purpose
for preserving as  confidential.  Issuer will use its best efforts to cause such
registration  statement first to become  effective as soon as practicable  after
the filing thereof and then to remain effective for such period not in excess of
180 days from the day such registration  statement first becomes  effective,  or
such   shorter  time  as  may  be  necessary  to  effect  such  sales  or  other
dispositions.  Grantee  shall have the right to demand  two such  registrations.
Grantee  shall  provide  all  information  reasonably  requested  by Issuer  for
inclusion in any  registration  statement to be filed  hereunder.  In connection
with any such  registration,  Issuer and Grantee  shall  provide each other with
representations,   warranties,   and  other  agreements   customarily  given  in
connection  with such  registrations.  If requested by any Grantee in connection
with  such  registration,  Issuer  and  Grantee  shall  become  a  party  to any
underwriting  agreement  relating to the sale of Option Shares,  but only to the
extent of  obligating  themselves  in  respect of  representations,  warranties,
indemnities  and other  agreements  customarily  included  in such  underwriting
agreements.  Notwithstanding  the  foregoing,  if Grantee  revokes any  exercise
notice or fails to  exercise  any Option  with  respect to any  exercise  notice
pursuant  to  Section  2(e),  Issuer  shall not be  obligated  to  continue  any
registration process with respect to the sale of Option Shares.

         (b) Additional  Persons With  Registration  Rights.  Upon receiving any
request  under this  Section 6 from any  Grantee,  Issuer  agrees to send a copy
thereof  to any other  person  known to Issuer to be  entitled  to  registration
rights under this Section 6, in each case by promptly mailing the same,  postage
prepaid,  to the  address of record of the  persons  entitled  to  receive  such
copies.  Notwithstanding  anything to the contrary contained herein, in no event
shall Issuer be obligated to effect more than two registrations pursuant to this
Section 6 by reason of the fact that there  shall be more than one  Grantee as a
result of any assignment or division of this Agreement.

         (c)  Expenses.   Except  where  applicable  state  law  prohibits  such
payments,   Issuer  will  pay  all  expenses   (including   without   limitation
registration fees, qualification fees, blue sky fees and expenses (including the
fees and expenses of counsel), legal expenses, including the reasonable fees and
expenses of one counsel to the holders whose Option Shares are being registered,
printing  expenses and the costs of special  audits or "cold  comfort"  letters,
expenses of  underwriters,  excluding  discounts and  commissions  but including
liability insurance if Issuer so desires or the underwriters so require, and the
reasonable  fees and expenses of any  necessary  special  experts) in connection
with each  registration  pursuant  to this  Section  6  (including  the  related
offerings and sales by holders of Option  Shares) and all other  qualifications,
notification or exemptions pursuant to Section 6.

         (d)  Indemnification.  In connection with any  registration  under this
Section 6, Issuer hereby indemnifies the Grantee, and each officer, director and
controlling  person of Grantee,  and each  underwriter  thereof,  including each
person,  if any who controls  such holder or  underwriter  within the meaning of
Section 15 of the Securities Act, against all expenses,  losses, claims, damages
and liabilities caused by any untrue, or alleged untrue,  statement contained in
any registration

                                       C-5

<PAGE>



statement or prospectus or  notification  or offering  circular  (including  any
amendments or supplements thereto) or any preliminary  prospectus,  or caused by
any omission,  or alleged omission, to state therein a material fact required to
be stated  therein or necessary to make the statements  therein not  misleading,
except insofar as such expenses,  losses, claims, damages or liabilities of such
indemnified party are caused by any untrue statement or alleged untrue statement
that was included by Issuer in any such registration  statement or prospectus or
notification  or offering  circular  (including  any  amendments or  supplements
thereto) in reliance  upon and in  conformity  with,  information  furnished  in
writing to Issuer by such  indemnified  party  expressly  for use  therein,  and
Issuer and each  officer,  director  and  controlling  person of Issuer shall be
indemnified by such Grantee, or by such underwriter, as the case may be, for all
such expenses,  losses, claims, damages and liabilities caused by any untrue, or
alleged untrue,  statement, that was included by Issuer in any such registration
statement or prospectus or  notification  or offering  circular  (including  any
amendments or supplements  thereto) in reliance  upon,  and in conformity  with,
information  furnished in writing to Issuer by such holder or such  underwriter,
as the case may be, expressly for such use.

         Promptly upon receipt by a party indemnified under this Section 6(d) of
notice of the  commencement  of any action  against  such  indemnified  party in
respect  of  which  indemnity  or  reimbursement   may  be  sought  against  any
indemnifying  party under this Section 6(d), such indemnified party shall notify
the indemnifying  party in writing of the  commencement of such action,  but the
failure  so to  notify  the  indemnifying  party  shall  not  relieve  it of any
liability  which it may  otherwise  have to any  indemnified  party  under  this
Section 6(d). In case notice of  commencement  of any such action shall be given
to the indemnifying  party as above provided,  the  indemnifying  party shall be
entitled  to  participate  in and, to the extent it may wish,  jointly  with any
other  indemnifying  party  similarly  notified,  to assume the  defense of such
action at its own expense, with counsel chosen by it and reasonably satisfactory
to such indemnified  party. The indemnified party shall have the right to employ
separate counsel in any such action and participate in the defense thereof,  but
the  fees  and  expenses  of  such  counsel  (other  than  reasonable  costs  of
investigation)   shall  be  paid  by  the  indemnified   party  unless  (i)  the
indemnifying  party either agrees to pay the same, (ii) the  indemnifying  party
fails to assume the  defense of such  action with  counsel  satisfactory  to the
indemnified  party, or (iii) the  indemnified  party has been advised by counsel
that one or more legal defenses may be available to the indemnifying  party that
may be contrary to the interests of the indemnified party. No indemnifying party
shall be liable for the fees and expenses of more than one separate  counsel for
all indemnified  parties or for any settlement entered into without its consent,
which consent may not be unreasonably withheld.

         If the indemnification provided for in this Section 6(d) is unavailable
to a party  otherwise  entitled to be  indemnified  in respect of any  expenses,
losses, claims, damages or liabilities referred to herein, then the indemnifying
party, in lieu of indemnifying such party otherwise  entitled to be indemnified,
shall  contribute to the amount paid or payable by such party to be  indemnified
as a result of such  expenses,  losses,  claims,  damages or liabilities in such
proportion  as is  appropriate  to reflect  the  relative  fault of Issuer,  the
Grantee and the  underwriters  in  connection  with the  statements or omissions
which resulted in such expenses, losses, claims, damages or liabilities, as well
as any other relevant equitable considerations.  The amount paid or payable by a
party as a result of the  expenses,  losses,  claims,  damages  and  liabilities
referred to above shall be deemed to include any legal or other fees or expenses
reasonably  incurred by such party in connection with investigating or defending
any action or claim;  provided,  however,  that in no case shall any  Grantee be
responsible,  in the  aggregate,  for any  amount in excess of the net  offering
proceeds  attributable to its Option Shares included in the offering.  No person
guilty of fraudulent  misrepresentation  (within the meaning of Section 11(f) of
the Securities  Act) shall be entitled to  contribution  from any person who was
not guilty of such fraudulent  misrepresentation.  Any obligation by any Grantee
to indemnify shall be several and not joint with other Grantees.

         (e)  Miscellaneous  Reporting.  Issuer shall comply with all  reporting
requirements and will do all such other things as may be necessary to permit the
expeditious  sale at any time of any  Option  Shares by the  Grantee  thereof in
accordance  with  and  to  the  extent  permitted  by  any  rule  or  regulation
promulgated by the SEC from time to time,  including,  without limitation,  Rule
144A.  Issuer  shall at its expense  provide the  Grantee  with any  information
necessary in connection  with the  completion and filing of any reports or forms
required to be filed by Grantee under the Securities Act or the Exchange Act, or
required  pursuant  to any  state  securities  laws or the  rules  of any  stock
exchange.

         SECTION 7.  Repurchase at the Option of Grantee or Owner.  (a) Upon the
occurrence  of a Repurchase  Event (as defined  below),  (i) at the request (the
date of such request being the "Request Date") of Grantee, delivered prior to an
Exercise  Termination Event,  Issuer (or any successor thereto) shall repurchase
the Option from Grantee at a price (the "Option  Repurchase Price") equal to the
amount by which (A) the  market/offer  price (as defined  below) exceeds (B) the
Option Price,  multiplied by the number of shares for which this Option may then
be exercised and (ii) at the request (the date

                                       C-6

<PAGE>
of such  request  being the "Request  Date") of the owner of Option  Shares from
time to time (the  "Owner"),  delivered  within 12 months of the occurrence of a
Repurchase  Event (or such later period as provided in Section 9),  Issuer shall
repurchase  such  number of the Option  Shares from the Owner as the Owner shall
designate  at a  price  (the  "Option  Share  Repurchase  Price")  equal  to the
market/offer price multiplied by the number of Option Shares so designated.  The
term  "market/offer  price" shall mean the highest of (i) the price per share of
Common  Stock at which a tender offer or exchange  offer  therefor has been made
after the date  hereof and on or prior to the Request  Date,  (ii) the price per
share of Common  Stock  paid or to be paid by any  third  party  pursuant  to an
agreement with Issuer (whether by way of a merger,  consolidation or otherwise),
(iii) the highest  last sale price for shares of Common  Stock within the 90-day
period  ending on the  Request  Date  quoted on the Nasdaq  National  Market (as
reported  by The Wall  Street  Journal,  or, if not  reported  thereby,  another
authoritative  source),  (iv) in the event of a sale of all or substantially all
of Issuer's  assets,  the sum of the price paid in such sale for such assets and
the current  market value of the  remaining  assets of Issuer as determined by a
nationally-recognized independent investment banking firm selected by Grantee or
the Owner,  as the case may be,  divided by the number of shares of Common Stock
outstanding at the time of such sale. In determining the market/offer price, the
value  of   consideration   other   than   cash   shall  be   determined   by  a
nationally-recognized independent investment banking firm selected by Grantee or
the Owner,  as the case may be,  whose  determination  shall be  conclusive  and
binding on all parties.

         (b) Grantee or the Owner, as the case may be, may exercise its right to
require  Issuer to repurchase  the Option  and/or any Option Shares  pursuant to
this  Section 7 by  surrendering  for such purpose to Issuer,  at its  principal
office,  a copy  of  this  Agreement  or  certificates  for  Option  Shares,  as
applicable,  accompanied by a written notice or notices  stating that Grantee or
the Owner, as the case may be, elects to require Issuer to repurchase the Option
and/or the Option Shares in accordance with the provisions of this Section 7. As
promptly as practicable,  and in any event within the later to occur of (x) five
business days after the surrender of the Option and/or certificates representing
Option Shares and the receipt of such notice or notices relating thereto and (y)
the time that is  immediately  prior to the  occurrence  of a Repurchase  Event,
Issuer shall  deliver or cause to be delivered to Grantee the Option  Repurchase
Price or to the Owner the Option Share  Repurchase Price therefor or the portion
thereof that Issuer is not then prohibited from so delivering  under  applicable
law and regulation.

         (c) Issuer hereby  undertakes to use its  reasonable  efforts to obtain
all required  regulatory and legal approvals and to file any required notices as
promptly as practicable in order to accomplish  any repurchase  contemplated  by
this  Section 7.  Nonetheless,  to the extent  that Issuer is  prohibited  under
applicable law or  regulation,  from  repurchasing  the Option and/or the Option
Shares in full,  Issuer shall  promptly so notify  Grantee  and/or the Owner and
thereafter  deliver  or cause to be  delivered,  from time to time,  to  Grantee
and/or the Owner, as appropriate, the portion of the Option Repurchase Price and
the Option Share Repurchase Price, respectively, that it is no longer prohibited
from delivering,  within five business days after the date on which Issuer is no
longer so  prohibited;  provided,  however,  that if  Issuer  at any time  after
delivery of a notice of repurchase  pursuant to Section 7(b) is prohibited under
applicable law or regulation,  from  delivering to Grantee and/or the Owner,  as
appropriate,  the Option  Repurchase Price or the Option Share Repurchase Price,
respectively,  in full or in any  substantial  part,  Grantee or the  Owner,  as
appropriate,  may revoke its  notice of  repurchase  of the Option or the Option
Shares  either in whole or in part  whereupon,  in the case of a  revocation  in
part,  Issuer  shall  promptly  (i)  deliver  to Grantee  and/or  the Owner,  as
appropriate,  that  portion of the  Option  Purchase  Price or the Option  Share
Repurchase Price that Issuer is not prohibited from delivering after taking into
account any such  revocation  and (ii) deliver,  as  appropriate,  either (A) to
Grantee, a new Agreement evidencing the right of Grantee to purchase that number
of shares  of  Common  Stock  equal to the  number  of  shares  of Common  Stock
purchasable  immediately  prior to the delivery of the notice of repurchase less
the  number of shares of Common  Stock  covered  by the  portion  of the  Option
repurchased or (B) to the Owner,  a certificate  for the number of Option Shares
covered by the revocation.

         (d) For purposes of this Section 7, a Repurchase  Event shall be deemed
to have  occurred  (i)  upon the  consummation  of any  Acquisition  Transaction
involving  Issuer or any Bank  Subsidiary  or (ii) upon the  acquisition  by any
person of  beneficial  ownership of securities  representing  25% or more of the
aggregate voting power of Issuer or any Bank  Subsidiary,  provided that no such
event shall  constitute a Repurchase  Event unless an Extension Event shall have
occurred prior to an Exercise  Termination  Event. The parties hereto agree that
Issuer's  obligations  to  repurchase  the  Option or Option  Shares  under this
Section 7 shall not terminate  upon the  occurrence  of an Exercise  Termination
Event if an Extension  Event shall have occurred  prior to the  occurrence of an
Exercise Termination Event.

         (e) Issuer  shall not enter into any  agreement  with any party  (other
than Grantee or a Grantee Subsidiary) for an Acquisition  Transaction unless the
other party  thereto  assumes  all the  obligations  of Issuer  pursuant to this
Section 7 in the event that Grantee or the Owner elects, in its sole discretion,
to require such other party to perform such obligations.

         SECTION 8. Substitute Option in the Event of Corporate  Change.  (a) In
the event that prior to an Exercise  Termination Event,  Issuer shall enter into
an agreement (i) to consolidate or merge with any person,  other than Grantee or
a Grantee Subsidiary,  and shall not be the continuing or surviving  corporation
of such consolidation or merger,  (ii) to permit any person,  other than Grantee
or a Grantee Subsidiary, to merge into Issuer and Issuer shall be the continuing
or  surviving  corporation,  but,  in  connection  with  such  merger,  the then
outstanding  shares of Common Stock shall be changed into or exchanged for stock
or other  securities  of any other  person or cash or any other  property or the
then  outstanding  shares of Common Stock shall after such merger represent less
than 50% of the aggregate  voting power of the merged company,  or (iii) to sell
or  otherwise  transfer  all or  substantially  all of its assets to any person,
other than Grantee or a Grantee  Subsidiary,  then,  and in each such case,  the
agreement  governing such  transaction  shall make proper  provision so that the
Option shall,  upon the  consummation of such transaction and upon the terms and
conditions set forth herein, be converted into, or exchanged for, an option (the
"Substitute  Option"),  at the election of Grantee,  of either (x) the Acquiring
Corporation  (as defined  below) or (y) any person that  controls the  Acquiring
Corporation  (the Acquiring  Corporation and any such  controlling  person being
hereinafter referred to as the Substitute Option Issuer)

         (b) The  Substitute  Option  shall be  exercisable  for such  number of
shares of the Substitute Common Stock (as is hereinafter defined) as is equal to
the  market/offer  price (as defined in Section 7)  multiplied  by the number of
shares of the Common  Stock for which the Option  was  theretofore  exercisable,
divided by the Average Price (as is  hereinafter  defined) The exercise price of
the Substitute  Option per share of the Substitute Common Stock (the "Substitute
Purchase  Price")  shall  then be  equal to the  Option  Price  multiplied  by a
fraction in which the  numerator is the number of shares of the Common Stock for
which the Option was  theretofore  exercisable and the denominator is the number
of shares  of  Substitute  Common  Stock  for  which  the  Substitute  Option is
exercisable.

         (c) The  Substitute  Option shall  otherwise have the same terms as the
Option,  provided that if the terms of the Substitute  Option cannot,  for legal
reasons,  be the same as the Option,  such terms shall be as similar as possible
and in no event less advantageous to Grantee, provided further that the terms of
the  Substitute  Option  shall  include (by way of example  and not  limitation)
provisions  for the repurchase of the  Substitute  Option and Substitute  Common
Stock by the  Substitute  Option  Issuer  on the same  terms and  conditions  as
provided in Section 7.

         (d) The following terms have the meanings indicated:

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

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

                  (iii)  "Average  Price" shall mean the average last sale price
         of a share of the  Substitute  Common  Stock (as  reported  by The Wall
         Street Journal or, if not reported  therein,  by another  authoritative
         source)  for the one  year  immediately  preceding  the  consolidation,
         merger or sale in  question,  but in no event higher than the last sale
         price of the shares of the Substitute Common Stock on the day preceding
         such  consolidation,  merger  or sale;  provided  that if Issuer is the
         issuer of the  Substitute  Option,  the Average Price shall be computed
         with respect to a share of common  stock  issued by Issuer,  the person
         merging into Issuer or by any company  which  controls or is controlled
         by such person, as Grantee may elect.

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

         SECTION 9. Extension of Time for Regulatory Approvals.  Notwithstanding
Sections 2(e), 6, 7 and 11, if

                                       C-8

<PAGE>



Grantee has given the notice  referred to in one or more of such  Sections,  the
exercise of the rights  specified in any such  Section  shall be extended (a) if
the exercise of such rights  requires  obtaining  regulatory  approvals,  to the
extent  necessary to obtain all  regulatory  approvals  for the exercise of such
rights,  and (b) to the extent  necessary to avoid liability under Section 16(b)
of the Securities  Exchange Act by reason of such exercise;  provided that in no
event shall any closing date occur more than 18 months after the related  Notice
Date, and, if the closing date shall not have occurred within such period due to
the failure to obtain any required  approval by the Federal Reserve Board or any
other  Governmental  Authority  despite the reasonable  efforts of Issuer or the
Substitute  Option  Issuer,  as the case may be, to obtain such  approvals,  the
exercise of the Option shall be deemed to have been  rescinded as of the related
Notice Date. In the event (a) Grantee receives  official notice that an approval
of the Federal Reserve Board or any other  Governmental  Authority  required for
the purchase and sale of the Option  Shares will not be issued or granted or (b)
a closing date has not occurred  within 18 months after the related  Notice Date
due to the  failure  to obtain  any such  required  approval,  Grantee  shall be
entitled  to  exercise  the Option in  connection  with the resale of the Option
Shares  pursuant to a  registration  statement as provided in Section 6. Nothing
contained in this Agreement shall restrict  Grantee from specifying  alternative
exercising of rights pursuant to Sections 2(e), 6, 7 and 11, hereof in the event
that the  exercising  of any such  rights  shall  not have  occurred  due to the
failure to obtain any required approval referred to in this Section 9.

         SECTION 10. Issuer Warranties. Issuer hereby represents and warrants to
Grantee as follows:

         (a) Issuer has the requisite  corporate  power and authority to execute
and deliver this  Agreement  and to  consummate  the  transactions  contemplated
hereby. The execution and delivery of this Agreement and the consummation of the
transactions  contemplated  hereby  have  been  duly  approved  by the  Board of
Directors of Issuer and no other corporate proceedings on the part of Issuer are
necessary to authorize  this  Agreement or to  consummate  the  transactions  so
contemplated.  This  Agreement  has been duly  executed  and  delivered  by, and
constitutes  a valid and binding  obligation  of,  Issuer,  enforceable  against
Issuer in accordance  with its terms,  except as  enforceability  thereof may be
limited by applicable  bankruptcy,  insolvency,  reorganization,  moratorium and
other similar laws affecting the enforcement of creditors'  rights generally and
institutions the deposits of which are insured by the Federal Deposit  Insurance
Corporation and except that the availability of the equitable remedy of specific
performance  or  injunctive  relief is  subject to the  discretion  of the court
before which any proceeding may be brought.

         (b) Issuer has taken all  necessary  corporate  action to authorize and
reserve and to permit it to issue, and at all times from the date hereof through
the  termination  of this  Agreement  in  accordance  with its  terms  will have
reserved for issuance upon the exercise of the Option,  that number of shares of
Common  Stock equal to the maximum  number of shares of Common Stock at any time
and from time to time  issuable  hereunder,  and all such shares,  upon issuance
pursuant  hereto,  will  be  duly  authorized,   validly  issued,   fully  paid,
nonassessable,  and will be  delivered  free and  clear  of all  claims,  liens,
encumbrances and security interests and not subject to any preemptive rights.

         (c) Upon receipt of the necessary  regulatory approvals as contemplated
by this  Agreement,  the execution,  delivery and  performance of this Agreement
does not or will not, and the  consummation by Issuer of any of the transactions
contemplated  hereby will not, constitute or result in (i) a breach or violation
of, or a default under, its certificate or articles of incorporation or by-laws,
or the comparable  governing  instruments of any of its subsidiaries,  or (ii) a
breach or violation of, or a default  under,  any  agreement,  lease,  contract,
note, mortgage,  indenture,  arrangement or other obligation of it or any of its
subsidiaries  (with or without the giving of notice,  the lapse of time or both)
or under any law,  rule,  ordinance or  regulation or judgment,  decree,  order,
award or governmental or  non-governmental  permit or license to which it or any
of its subsidiaries is subject, that would in any case give any other person the
ability to prevent or enjoin  Issuer's  performance  under this Agreement in any
material respect.

         SECTION 11. Assignment of Option by Grantee. (a) Neither of the parties
hereto may assign any of its rights or  delegate  any of its  obligations  under
this Agreement or the Option  created  hereunder to any other person without the
express written consent of the other party,  except that Grantee may assign this
Agreement or any of its rights  hereunder in whole or in part (i) at any time to
a subsidiary of Grantee,  and (ii) after the  occurrence of a Purchase  Event to
any Person; provided, however, that until the date 15 days following the date at
which the Federal Reserve Board approves an application by Grantee under the BHC
Act to acquire the shares of Common Stock subject to the Option, Grantee may not
assign  its  rights  under the Option  except in (A) a widely  dispersed  public
distribution,  (B) a private  placement in which no one party acquires the right
to purchase  securities  representing  in excess of 2% of the  aggregate  voting
power  of  Issuer,  (C) an  assignment  to a single  party  (e.g.,  a broker  or
investment banker) for the purpose of conducting a widely dispersed public

                                       C-9

<PAGE>



distribution  on  Grantee's  behalf,  or (D) any other  manner  approved  by the
Federal Reserve Board.  Grantee will pay any reasonable  out-of-pocket costs and
expenses of Issuer in connection with any such assignment. The term "Grantee" as
used in this  Agreement  shall  also be deemed to refer to  Grantee's  permitted
assigns.

         (b) Any  assignment of rights of Grantee to any  permitted  assignee of
Grantee  hereunder  shall bear the restrictive  legend at the beginning  thereof
substantially as follows:

         "The  transfer of the option  represented  by this  assignment  and the
         related  option  agreement  is subject to resale  restrictions  arising
         under the Securities Act of 1933, as amended and to certain  provisions
         of an agreement between Summit Bancorp.  and NMBT CORP ("Issuer") dated
         as of the 4th day of October, 1999. A copy of such agreement is on file
         at the principal office of Issuer and will be provided to any permitted
         assignee  of the  Option  without  change  upon  receipt by Issuer of a
         written request therefor."

It is understood and agreed that (i) the reference to the resale restrictions of
the  Securities  Act in the  above  legend  shall  be  removed  by  delivery  of
substitute assignments without such reference if Grantee shall have delivered to
Issuer a copy of a letter  from the staff of the SEC,  or an opinion of counsel,
in form and substance  satisfactory to Issuer, to the effect that such legend is
not required  for  purposes of the  Securities  Act;  (ii) the  reference to the
provisions of this Agreement in the above legend shall be removed by delivery of
substitute  assignments  without  such  reference if the Option has been sold or
transferred  in  compliance  with the  provisions  of this  Agreement  and under
circumstances that do not require the retention of such reference; and (iii) the
legend  shall be removed in its  entirety  if the  conditions  in the  preceding
clauses (i) and (ii) are both satisfied.  In addition,  such  assignments  shall
bear any other legend as may be required by law.

         SECTION 12. Application for Regulatory Approval. If Grantee is entitled
to exercise the Option and has sent a notice to Issuer pursuant to Section 2(e),
each of Grantee and Issuer will use its  reasonable  efforts to make all filings
with, and to obtain consents of, all third parties and the Federal Reserve Board
and  other  Governmental  Authorities  necessary  to  the  consummation  of  the
transactions  contemplated by this  Agreement,  including,  without  limitation,
making  application for listing or quotation,  as the case may be, of the shares
of Common Stock  issuable  hereunder on the NASDAQ  National  Market  System and
applying to the  Federal  Reserve  Board under the BHC Act and to state  banking
authorities for approval to acquire the shares issuable hereunder.

         SECTION 13. Specific  Performance.  The parties hereto acknowledge that
damages would be an inadequate  remedy for a breach of this  Agreement by either
party hereto and that the obligations of the parties shall hereto be enforceable
by either  party hereto  through  injunctive  or other  equitable  relief.  Both
parties  further agree to waive any  requirement  for the securing or posting of
any bond in connection with the obtaining of any such equitable  relief and that
this provision is without  prejudice to any other rights that the parties hereto
may have for any failure to perform this Agreement.

         SECTION  14.  Separability  of  Provisions.  If  any  term,  provision,
covenant or  restriction  contained  in this  Agreement  is held by a court or a
federal or state regulatory agency of competent jurisdiction to be invalid, void
or  unenforceable,  the  remainder of the terms,  provisions  and  covenants and
restrictions  contained in this Agreement shall remain in full force and effect,
and shall in no way be affected, impaired or invalidated. If for any reason such
court or regulatory  agency determines that Grantee is not permitted to acquire,
or Issuer is not permitted to repurchase, pursuant to Section 7, the full number
of shares of Common Stock provided in Section 1 (as adjusted  pursuant  hereto),
it is the express  intention of Issuer to allow Grantee to acquire or to require
Issuer to repurchase such lesser number of shares as may be permissible, without
any amendment or modification hereof.

         SECTION 15. Notices. All notices,  requests,  claims, demands and other
communications  hereunder shall be deemed to have been duly given when delivered
in person, by cable, telegram,  telecopy or telex, or by registered or certified
mail (postage prepaid,  return receipt requested) at the respective addresses of
the parties set forth in the Merger Agreement.

         SECTION 16.  Governing  Law.  This  Agreement  shall be governed by and
construed in accordance with the laws of the State of New Jersey.

         SECTION 17. Counterparts. This Agreement may be executed in two or more
counterparts,  each of which shall be deemed to be an original, but all of which
shall constitute one and the same agreement.

         SECTION 18. Expenses.  Except as otherwise  expressly  provided herein,
each of the parties hereto shall bear and pay all costs and expenses incurred by
it or on its behalf in connection with the transactions  contemplated hereunder,
including  fees  and  expenses  of its  own  financial  consultants,  investment
bankers, accountants and counsel.

         SECTION 19. Entire Agreement; No Third-Party  Beneficiaries.  Except as
otherwise  expressly provided herein or in the Merger Agreement,  this Agreement
contains  the  entire  agreement   between  the  parties  with  respect  to  the
transactions  contemplated  hereunder and supersedes all prior  arrangements  or
understandings  with respect thereof,  written or oral. The terms and conditions
of this Agreement  shall inure to the benefit of and be binding upon the parties
hereto and their respective  successors and permitted  assigns.  Nothing in this
Agreement,  expressed  or implied,  is intended to confer upon any party,  other
than the parties  hereto,  and their  respective  successors  and  assigns,  any
rights,  remedies,  obligations  or  liabilities  under  or by  reason  of  this
Agreement, except as expressly provided herein.

         SECTION 20. Merger Agreement. Nothing contained in this Agreement shall
be deemed to authorize  Issuer or Grantee to breach any  provision of the Merger
Agreement.

         SECTION 21.  Majority in Interest.  In the event that any  selection or
determination is to be made by Grantee or the Owner hereunder and at the time of
such selection or  determination  there is more than one Grantee or Owner,  such
selection shall be made by a majority in interest of such Grantees or Owners.

         SECTION 22.  Further  Assurances.  In the event of any  exercise of the
Option by Grantee,  Issuer and such Grantee  shall execute and deliver all other
documents  and  instruments  and take all other  action  that may be  reasonably
necessary in order to consummate the transactions provided for by such exercise.

         SECTION  23. No Rights as  Shareholder.  Except to the  extent  Grantee
exercises the Option,  Grantee shall have no rights to vote or receive dividends
or have any other rights as a shareholder with respect to shares of Common Stock
covered hereby.

         SECTION 24. Grantee Representation. The Option and any Option Shares or
other securities  acquired by Grantee upon exercise of the Option are not being,
and  will  not be,  as the  case  may  be,  acquired  with a view to the  public
distribution  thereof in the United  States except as provided for in Sections 6
and 11 hereof and neither the Option nor any Option  Shares or other  securities
acquired by Grantee upon exercise of the Option will be transferred or otherwise
disposed  of by  Grantee  except in a  transaction  registered  or  exempt  from
registration under the Securities Act.

                                   SECTION 262

                        DELAWARE GENERAL CORPORATION LAW

      262 Appraisal  Rights--(a)  Any stockholder of a corporation of this State
who holds  shares of stock on the date of the  making  of a demand  pursuant  to
subsection  (d) of this section with  respect to such shares,  who  continuously
holds such shares through the effective date of the merger or consolidation, who
has otherwise  complied with  subsection (d) of this section and who has neither
voted in favor of the merger or consolidation  nor consented  thereto in writing
pursuant to sec.  228 of this title shall be  entitled  to an  appraisal  by the
Court of Chancery of the fair value of the  stockholder's  shares of stock under
the circumstances  described in subsections (b) and (c) of this section. As used
in this section,  the word "stockholder"  means a holder of record of stock in a
stock  corporation  and also a member of record of a nonstock  corporation:  the
words  "stock" and "share"  mean and include what is  ordinarily  meant by those
words and also  membership  or  membership  interest  of a member of a  nonstock
corporation;  and  the  words  "depository  receipt"  mean a  receipt  or  other
instrument  issued  by a  depository  representing  an  interest  in one or more
shares, or fractions thereof,  solely of stock of a corporation,  which stock is
deposited with the depository.

      (b)  Appraisal  rights shall be  available  for the shares of any class or
           series  of  stock  of  a  constituent  corporation  in  a  merger  or
           consolidation  to be  effected  pursuant  to sec.  251 (other  than a
           merger  effected  pursuant to sec.  251(g) of this title),  sec. 252,
           sec. 254, sec. 257, sec. 258, sec. 263 or sec. 264 of this title:

           (1)  Provided,  however,  that no appraisal rights under this section
                shall be  available  for the  shares  of any  class or series of
                stock,  which stock, or depository  receipts in respect thereof,
                at the record date fixed to determine the stockholders  entitled
                to receive notice of and to vote at the meeting of  stockholders
                to act upon the  agreement  of  merger  or  consolidation,  were
                either  (i)  listed  on  a  national   securities   exchange  or
                designated  as  a  national   market   system   security  on  an
                interdealer  quotation  system by the  National  Association  of
                Securities  Dealers,  Inc.  or (ii)  held of record by more than
                2,000  holders;  and further  provided that no appraisal  rights
                shall be  available  for any shares of stock of the  constituent
                corporation surviving a merger if the merger did not require for
                its  approval  the  vote of the  stockholders  of the  surviving
                corporation  as provided in  subsection  (f) of sec. 251 of this
                title.

           (2)  Notwithstanding  paragraph  (1) of  this  subsection,  appraisal
                rights under this section  shall be available  for the shares of

                holders  thereof are  required by the terms of an  agreement  of
                merger or  consolidation  if the holders thereof are required by
                the terms of an agreement of merger or consolidation pursuant to

                   receipts at the effective date of the merger or consolidation
                   will be either  listed on a national  securities  exchange or

      (c)  Any corporation may provide in its certificate of incorporation that
           appraisal rights under this section shall be available for the shares
           of any class or series of its stock as a result of an amendment to
           its certificate of incorporation, any merger or consolidation in
           which the corporation is a constituent corporation or the sale of all
           or substantially all of the assets of the corporation. If the
           certificate of incorporation contains such a provision, the
           procedures of this section, including those set forth in subsections
           (d) and (e) of this section, shall apply as nearly as is practicable.

      (d)  Appraisal rights shall be perfected as follows:

           (1)  If a proposed merger or consolidation for which appraisal rights
                are provided  under this section is to be submitted for approval
                at a meeting of stockholders,  the corporation, not less than 20
                days prior to the meeting, shall notify each of its stockholders
                who was such on the record date for such meeting with respect to
                shares for which  appraisal  rights are  available  pursuant  to
                subsections  (b)  or  (c)  hereof  that  appraisal   rights  are
                available  for  any  or all of  the  shares  of the  constituent
                corporations,  and shall  include in such  notice a copy of this
                section.  Each  stockholder  electing to demand the appraisal of
                (1)such  stockholder's  shares shall deliver to the corporation,
                before the taking of the vote on the merger or consolidation,  a
                written  demand for appraisal of (1)such  stockholder's  shares.
                Such  demand will be  sufficient  if it  reasonably  informs the
                corporation  of the  identity  of the  stockholder  and that the
                stockholder  intends  thereby to demand the appraisal of (1)such
                stockholder's  shares.  A proxy or vote  against  the  merger or
                consolidation  shall not constitute such a demand. A stockholder
                electing to take such  action  must do so by a separate  written
                demand as herein  provided.  Within 10 days after the  effective
                date of such merger or consolidation, the surviving or resulting
                corporation  shall notify each  stockholder of each  constituent
                corporation  who has complied with this  subsection  and has not
                voted in favor of or consented to the merger or consolidation of
                the date that the merger or consolidation  has become effective;
                or

           (2)  If the merger or consolidation  was approved pursuant to sec.228
                or sec.253 of this title, each constituent  corporation,  either
                before  the  effective  date of the merger or  consolidation  or
                within ten days thereafter,  shall notify each of the holders of
                any class or series of stock of such constituent corporation who
                are entitled to  appraisal  rights of the approval of the merger
                or consolidation and that appraisal rights are available for any
                or all  shares  of  such  class  or  series  of  stock  of  such
                constituent corporation, and shall include in such notice a copy
                of this  section;  provided  that,  if the notice is given on or
                after the effective  date of the merger or  consolidation,  such
                notice shall be given by the surviving or resulting  corporation
                to all  such  holders  of any  class  or  series  of  stock of a
                constituent  corporation that are entitled to appraisal  rights.
                Such notice may, and, if given on or after the effective date of
                the  merger  or   consolidation,   shall,   also   notify   such
                stockholders   of  the   effective   date  of  the   merger   or
                consolidation. Any stockholder entitled to appraisal rights may,
                within 20 days after the date of mailing of such notice,  demand
                in writing  from the  surviving  or  resulting  corporation  the
                appraisal  of  such  holder's   shares.   Such  demand  will  be
                sufficient  if it  reasonably  informs  the  corporation  of the
                identity of the  stockholder  and that the  stockholder  intends
                thereby to demand the appraisal of such holder's shares. If such
                notice did not notify  stockholders of the effective date of the
                merger  or  consolidation,  either  (i)  each  such  constituent
                corporation shall send a second notice before the effective date
                of the merger or consolidation  notifying each of the holders of
                any  class or series  of stock of such  constituent  corporation
                that are entitled to appraisal  rights of the effective  date of
                the merger or  consolidation  or (ii) the surviving or resulting
                corporation  shall send such a second notice to all such holders
                on or  within  10 days  after  such  effective  date;  provided,
                however,  that if such  second  notice is sent more than 20 days
                following  the sending of the first  notice,  such second notice
                need  only  be  sent  to each  stockholder  who is  entitled  to
                appraisal rights and who has demanded appraisal of such holder's
                shares in accordance with this  subsection.  An affidavit of the
                secretary or assistant secretary or of the transfer agent of the
                corporation  that is required  to give  either  notice that such
                notice has been given shall,  in the absence of fraud,  be prima
                facie  evidence of the facts  stated  therein.  For  purposes of
                determining the stockholders  entitled to receive either notice,
                each constituent  corporation may fix, in advance, a record date
                that shall be not more than 10 days prior to the date the notice
                is given, provided,  that if the notice is given on or after the
                effective date of the merger or  consolidation,  the record date
                shall be such effective date. If no record date is fixed and the
                notice is given  prior to the  effective  date,  the record date
                shall be the close of business on the day next preceding the day
                on which the notice is given.

      (e)  Within  120  days  after  the   effective   date  of  the  merger  or
           consolidation,   the  surviving  or  resulting   corporation  or  any
           stockholder who has complied with  subsections (a) and (d) hereof and
           who is otherwise entitled to appraisal rights, may file a petition in
           the Court of Chancery  demanding a determination  of the value of the
           stock of all such stockholders. Notwithstanding the foregoing, at any
           time  within  60 days  after  the  effective  date of the  merger  or
           consolidation,  any  stockholder  shall  have the  right to  withdraw
           (1)such  stockholder's  demand for  appraisal and to accept the terms
           offered upon the merger or  consolidation.  Within 120 days after the
           effective date of the merger or  consolidation,  any  stockholder who
           has complied with the requirements of subsections (a) and (d) hereof,
           upon  written  request,   shall  be  entitled  to  receive  from  the
           corporation  surviving the merger or resulting from the consolidation
           a statement setting forth the aggregate number of shares not voted in
           favor  of the  merger  or  consolidation  and with  respect  to which
           demands for appraisal have been received and the aggregate  number of
           holders of such shares. Such written statement shall be mailed to the
           stockholder  within  10  days  after(1)  such  stockholder's  written
           request  for  such  a  statement  is  received  by the  surviving  or
           resulting  corporation  or within  10 days  after  expiration  of the
           period for delivery of demands for  appraisal  under  subsection  (d)
           hereof, whichever is later.

      (f)  Upon the filing of any such petition by a  stockholder,  service of a
           copy  thereof   shall  be  made  upon  the   surviving  or  resulting
           corporation,  which shall  within 20 days after such  service file in
           the office of the  Register  in Chancery  in which the  petition  was
           filed a duly verified list  containing the names and addresses of all
           stockholders who have demanded payment for their shares and with whom
           agreements  as to the value of their  shares have not been reached by
           the  surviving or  resulting  corporation.  If the petition  shall be
           filed by the surviving or resulting  corporation,  the petition shall
           be  accompanied  by  such a  duly  verified  list.  The  Register  in
           Chancery,  if so ordered by the Court,  shall give notice of the time
           and place fixed for the hearing of such  petition  by  registered  or
           certified mail to the surviving or resulting  corporation  and to the
           stockholders shown on the list at the addresses therein stated.  Such
           notice shall also be given by 1 or more  publications at least 1 week
           before the day of the hearing,  in a newspaper of general circulation
           published in the City of Wilmington,  Delaware or such publication as
           the Court  deems  advisable.  The forms of the notices by mail and by
           publication  shall be  approved by the Court,  and the costs  thereof
           shall be borne by the surviving or resulting corporation.

      (g)  At the  hearing  on such  petition,  the Court  shall  determine  the
           stockholders  who have complied with this section and who have become
           entitled to appraisal rights.  The Court may require the stockholders
           who have  demanded an  appraisal  for their shares and who hold stock
           represented by certificates to submit their  certificates of stock to
           the Register in Chancery for notation  thereon of the pendency of the
           appraisal  proceedings;  and if any stockholder  fails to comply with
           such  direction,  the Court may  dismiss the  proceedings  as to such
           stockholder.

      (h)  After  determining  the  stockholders  entitled to an appraisal,  the
           Court  shall  appraise  the  shares,  determining  their  fair  value
           exclusive of any element of value arising from the  accomplishment or
           expectation of the merger or consolidation, together with a fair rate
           of interest,  if any, to be paid upon the amount determined to be the
           fair value. In determining such fair value, the Court shall take into
           account  all  relevant  factors.  In  determinating  the fair rate of
           interest, the Court may consider all relevant factors,  including the
           rate of interest which the surviving or resulting  corporation  would
           have  had  to  pay  to  borrow  money  during  the  pendency  of  the
           proceeding.   Upon   application   by  the   surviving  or  resulting
           corporation  or by any  stockholder  entitled to  participate  in the
           appraisal  proceeding,  the  Court  may,  in its  discretion,  permit
           discovery or other pretrial proceedings and may proceed to trial upon
           the appraisal  prior to the final  determination  of the  stockholder
           entitled to an appraisal.  Any stockholder  whose name appears on the
           list filed by the  surviving  or  resulting  corporation  pursuant to
           subsection   (f)  of  this  section  and  who  has   submitted   such
           stockholder's  certificates of stock to the Register in Chancery,  if
           such is required,  may participate  fully in all proceedings until it
           is finally  determined  that (1)such  stockholder  is not entitled to
           appraisal rights under this section.

      (i)  The Court  shall  direct the payment of the fair value of the shares,
           together  with  interest,  if  any,  by the  surviving  or  resulting
           corporation to the  stockholders  entitled  thereto.  Interest may be
           simple or compound, as the Court may direct. Payment shall be so made
           to each such  stockholder,  in the case of holders of  uncertificated
           stock  forthwith,  and the case of holders of shares  represented  by
           certificates   upon  the   surrender  to  the   corporation   of  the
           certificates  representing  such  stock.  The  Court's  decree may be
           enforced as other  decrees in the Court of Chancery  may be enforced,
           whether such  surviving or resulting  corporation be a corporation of
           this State or of any state.

                                      D-3

      (j)  The costs of the  proceeding may be determined by the Court and taxed
           upon the parties as the Court deems  equitable in the  circumstances.
           Upon  application  of a  stockholder,  the  Court  may order all or a
           portion of the expenses  incurred by any  stockholder  in  connection
           with  the  appraisal  proceeding,   including,   without  limitation,
           reasonable  attorney's fees and the fees and expenses of experts,  to
           be charged pro rata  against the value of all the shares  entitled to
           an appraisal.

      (k)  From and after the effective date of the merger or consolidation,  no
           stockholder  who  has  demanded   appraisal  rights  as  provided  in
           subsection  (d) of this section  shall be entitled to vote such stock
           for  any  purpose  or  to  receive  payment  of  dividends  or  other
           distributions on the stock (except  dividends or other  distributions
           payable  to  stockholders  of record at a date  which is prior to the
           effective date of the merger or  consolidation);  provided,  however,
           that if no petition for an  appraisal  shall be filed within the time
           provided in subsection  (e) of this section,  or if such  stockholder
           shall  deliver to the  surviving or resulting  corporation  a written
           withdrawal  of such  stockholder's  demand  for an  appraisal  and an
           acceptance  of the  merger or  consolidation,  either  within 60 days
           after the effective date of the merger or  consolidation  as provided
           in  subsection  (e) of this  section or  thereafter  with the written
           approval of the corporation, then the right of such stockholder to an
           appraisal shall cease.  Notwithstanding  the foregoing,  no appraisal
           proceeding  in the Court of  Chancery  shall be  dismissed  as to any
           stockholder  without the approval of the Court, and such approval may
           be conditioned upon such terms as the Court deems just.

      (l)  The shares of the  surviving  or resulting  corporation  to which the
           shares of such objecting  stockholders  would have been converted had
           they assented to the merger or consolidation shall have the status of
           authorized  and  unissued   shares  of  the  surviving  or  resulting
           corporation.

                     INFORMATION NOT REQUIRED IN PROSPECTUS


ITEM 20. INDEMNIFICATION OF DIRECTORS AND OFFICERS

      With respect to the  indemnification of directors and officers,  Section 5
of Article IX of the By-Laws of Summit Bancorp. provides


      Section 5.  INDEMNIFICATION  AND  INSURANCE  (a) Each person who was or is
made a  party  or is  threatened  to be made a party  to or is  involved  in any
proceeding,  by reason of the fact that he or she is or was a corporate agent of
the  Corporation,  whether the basis of such  proceeding is alleged action in an
official capacity as a corporate agent or in any other capacity while serving as
a corporate agent,  shall be indemnified and held harmless by the Corporation to
the fullest extent authorized by the laws of the State of New Jersey as the same
exists or may hereafter be amended (but, in the case of any such amendment, only
to the extent that such amendment  permits the  Corporation  to provide  broader
indemnification  rights than said law permitted the Corporation to provide prior
to  such  amendment),   against  all  expenses  and  liabilities  in  connection
therewith, and such indemnification shall continue as to a person who has ceased
to be a corporate agent and shall inure to the benefit of such corporate agent's
heirs,  executors,  administrators  and other legal  representatives;  PROVIDED,
HOWEVER, that except as provided in Section 5(c) of this By-Law, the Corporation
shall  indemnify any such person seeking  indemnification  in connection  with a
proceeding  (or part thereof)  initiated by such person only if such  proceeding
(or part  thereof)  was  authorized  by the  Board of  Directors.  The  right to
indemnification  conferred  in this By-Law  shall be a contract  right and shall
include  the  right  to be paid by the  Corporation  the  expenses  incurred  in
defending any such proceeding in advance of its final disposition, such advances
to be  paid  by  the  Corporation  within  20  days  after  the  receipt  by the
Corporation  of a statement  or  statements  from the claimant  requesting  such
advance or advances from time to time; PROVIDED,  HOWEVER,  that the advancement
of counsel fees to a claimant  other than a claimant who is or was a director or
Executive Vice President or higher ranking officer of the  Corporation  shall be
made only when the Board of Directors or the General  Counsel of the Corporation
determines that  arrangements  for counsel are  satisfactory to the Corporation;
and PROVIDED,  FURTHER,  that if the laws of the State of New Jersey so require,
the payment of such  expenses  incurred by a corporate  agent in such  corporate
agent's  capacity as a corporate  agent (and not in any other  capacity in which
service was or is rendered by such person  while a corporate  agent,  including,
without limitation, service to an employee benefit plan) in advance of the final
disposition of a proceeding  shall be made only upon delivery to the Corporation
of an undertaking  by or on behalf of such corporate  agent to repay all amounts
so advanced if it shall  ultimately be determined  that such corporate  agent is
not entitled to be indemnified under this By-Law or otherwise.


      (b) To obtain  indemnification  under this By-Law, a claimant shall submit
to the  Corporation  a written  request,  including  therein or  therewith  such
documentation and information as is reasonably  available to the claimant and is
reasonably  necessary  to  determine  whether and to what extent the claimant is
entitled  to   indemnification.   Upon   written   request  by  a  claimant  for
indemnification  pursuant  to  the  first  sentence  of  this  Section  5(b),  a
determination,  if required by applicable  law,  with respect to the  claimant's
entitlement thereto shall be made as follows: (1) if requested by a claimant who
is or was a director or Executive Vice  President or higher  ranking  officer of
this Corporation,  by independent counsel (as hereinafter  defined) in a written
opinion to the Board of  Directors,  a copy of which shall be  delivered  to the
claimant;  or (2) if the claimant is not a person  described in Section 5(b)(1),
or is  such a  person  and if no  request  is  made  by  such a  claimant  for a
      determination by independent counsel, (A) by the Board of Directors by a
majority vote of a quorum consisting of disinterested  directors (as hereinafter
defined),  or  (B)  if  a  quorum  of  the  Board  of  Directors  consisting  of
disinterested directors is not obtainable or, even if obtainable, such quorum of
disinterested  directors so directs, by independent counsel in a written opinion
to the Board of  Directors,  a copy of which shall be delivered to the claimant.
In the event the determination of entitlement to  indemnification  is to be made
by independent  counsel at the request of the claimant,  the independent counsel
shall be selected by the Board of Directors and paid by the  Corporation.  If it
is so determined  that the claimant is entitled to  indemnification,  payment to
the claimant shall be made within 20 days after such determination.

      (c) If a claim  under  Section  5(a) of this By-Law is not paid in full by
the  Corporation  within thirty days after a written  claim  pursuant to Section
5(b) of this By-Law has been  received by the  Corporation,  the claimant may at
any time  thereafter  bring suit against the  Corporation  to recover the unpaid
amount of the claim and, if successful in whole

                                      II-1

<PAGE>

or in part,  the  claimant  shall be  entitled  to be paid also the  expense  of
prosecuting such claim,  including attorney's fees. It shall be a defense to any
such  action  (other  than an action  brought  to  enforce a claim for  expenses
incurred in defending any proceeding in advance of its final  disposition  where
the  required  undertaking,  if  any  is  required,  has  been  tendered  to the
Corporation)  that the claimant has not met the standard of conduct  which makes
it permissible  under the laws of the State of New Jersey for the Corporation to
indemnify  the claimant for the amount  claimed,  but the burden of proving such
defense  shall be on the  Corporation.  Neither the  failure of the  Corporation
(including  its  Board of  Directors  or  independent  counsel)  to have  made a
determination  prior to the commencement of such action that  indemnification of
the  claimant is proper in the  circumstances  because the  claimant has met the
applicable standard of conduct set forth in the laws of the State of New Jersey,
nor an actual determination by the Corporation (including its Board of Directors
or independent  counsel) that the claimant has not met such applicable  standard
of conduct,  shall be a defense to the action or create a  presumption  that the
claimant has not met the applicable standard of conduct.

      (d) If a  determination  shall have been made  pursuant to Section 5(b) of
this By-Law that the claimant is entitled to  indemnification,  the  Corporation
shall  be bound  by such  determination  in any  judicial  proceeding  commenced
pursuant to Section 5(c) of this By-Law.

      (e) The right to  indemnification  and the payment of expenses incurred in
defending a  proceeding  in advance of its final  disposition  conferred in this
By-Law  shall not be  exclusive of any other rights which any person may have or
hereafter   acquire  under  any  statute,   provision  of  the   Certificate  of
Incorporation,   By-Laws,  agreement,  vote  of  shareholders  or  disinterested
directors or otherwise.  No repeal or  modification  of this By-Law shall in any
way  diminish  or  adversely  affect  the rights of any  corporate  agent of the
Corporation  hereunder in respect of any  occurrence or matter  arising prior to
any such repeal or modification.

      (f) The Corporation  may maintain  insurance,  at its expense,  to protect
itself and any corporate  agent of the Corporation or other  enterprise  against
any expense or liability, whether or not the Corporation would have the power to
indemnify  such person  against such expense or liability  under the laws of the
State of New Jersey.

      (g) If any  provision  or  provisions  of this By-Law  shall be held to be
invalid,  illegal or unenforceable for any reason whatsoever:  (1) the validity,
legality  and  enforceability  of  the  remaining   provisions  of  this  By-Law
(including,  without  limitation,  each  portion of any  section of this  By-Law
containing  any such  provision  held to be invalid,  illegal or  unenforceable)
shall not in any way be  affected or  impaired  thereby;  and (2) to the fullest
extent possible,  the provisions of this By-Law (including,  without limitation,
each such portion of any section of this By-Law  containing  any such  provision
held to be invalid,  illegal or unenforceable)  shall be construed so as to give
effect to the  intent  manifested  by the  provision  held  invalid,  illegal or
unenforceable.

      (h) For purposes of this By-Law:

          (1)  "disinterested  director" means a director of the Corporation who
      is not and was not a party  to or  otherwise  involved  in the  matter  in
      respect of which indemnification is sought by the claimant.

          (2) "independent counsel" means a law firm, a member of a law firm, or
      an independent  practitioner that is experienced in matters of corporation
      law and shall include any person who,  under the  applicable  standards of
      professional  conduct  then  prevailing,  would  not  have a  conflict  of
      interest in  representing  either the  Corporation  or the  claimant in an
      action to determine the claimant's rights under this By-Law.

          (3)  "corporate  agent"  means any  person  who is or was a  director,
      officer,  employee  or  agent  of the  Corporation  or of any  constituent
      corporation  absorbed by the Corporation in an consolidation or merger and
      any person who is or was a director,  officer,  trustee, employee or agent
      of any subsidiary of the Corporation or of any other  enterprise,  serving
      as such at the  request of this  Corporation,  or of any such  constituent
      corporation,  or the legal  representative of any such director,  officer,
      trustee, employee or agent;

          (4) "other  enterprise"  means any  domestic  or foreign  corporation,
      other than the  Corporation,  and any  partnership,  joint  venture,  sole
      proprietorship,  trust or other  enterprise,  whether  or not for  profit,
      served by a corporate agent;

          (5) "expenses" means reasonable costs, disbursements and counsel fees;

          (6)  "liabilities"  means amounts paid or incurred in  satisfaction of
      settlements, judgments, fines and penalties;

                                      II-2

<PAGE>


          (7)  "proceeding"  means any pending,  threatened or completed  civil,
      criminal,  administrative,   legislative,   investigative  or  arbitrative
      action,  suit or  proceeding,  and any appeal  therein  and any inquiry or
      investigation which could lead to such action, suit or proceeding; and

          (8) References to "other enterprises"  include employee benefit plans;
      references to "fines"  include any excise taxes  assessed on a person with
      respect to an employee  benefit  plan;  and  references to "serving at the
      request  of  the  indemnifying  corporation"  include  any  service  as  a
      corporate  agent which  imposes  duties on, or involves  services  by, the
      corporate   agent  with  respect  to  an  employee   benefit   plan,   its
      participants,  or beneficiaries;  and a person who acted in good faith and
      in a manner the person  reasonably  believed to be in the  interest of the
      participants and beneficiaries of an employee benefit plan shall be deemed
      to have  acted in a manner  "not  opposed  to the  best  interests  of the
      corporation."

      (i) Any notice, request or other communication required or permitted to be
given to the  Corporation  under  this  By-Law  shall be in  writing  and either
delivered in person or sent by facsimile,  telex,  telegram,  overnight  mail or
courier  service,  or certified or  registered  mail,  postage  prepaid,  return
receipt  requested,  to the Secretary of the  Corporation and shall be effective
only upon receipt by the  Secretary.

      (j)  This  By-Law  shall be  implemented  and  construed  to  provide  any
corporate  agent described above who is found to have acted in good faith and in
a manner  such  person  reasonably  believed to be in or not opposed to the best
interests  of  the  Corporation  the  maximum  indemnification,  advancement  of
expenses, and reimbursement for liabilities and expenses allowed by law.

      Such  provision  is  consistent  with  Section  14A:3-5  of  the  Business
Corporation Act of the State of New Jersey, the state of Summit's incorporation,
which  permits the  indemnification  of officers and  directors,  under  certain
circumstances and subject to specified limitations,  against liability which any
officer or director may incur in such capacity.

      Article 7 of Summit's Restated Certificate of Incorporation provides that:

      Except to the extent  prohibited  by law,  no  Director  or officer of the
Corporation  shall be personally  liable to the Corporation or its  shareholders
for damages for breach of any duty owned to the Corporation or its  shareholders
provided that a Director or officer shall not be relieved from liability for any
breach of duty based upon an act or omission  (a) in breach of such persons duty
of  loyalty to the  Corporation  or its  shareholders,  (b) not in good faith or
involving a knowing  violation of law or (c) resulting in receipt of an improper
personal  benefit.  Neither the  amendment  or repeal of this Article 7, nor the
adoption  of  any  provision  of  this  Restated  Certificate  of  Incorporation
inconsistent  with this  Article 7, nor the  adoption of any  provision  of this
Restated  Certificate of Incorporation  inconsistent  with this Article 7, shall
eliminate  or reduce the effect of this Article 7 in respect of any matter which
occurred,  or any cause of action,  suit or claim  which but for this  Article 7
would have  accrued  or arisen,  prior to such  amendment,  repeal or  adoption.


      Summit carries officers' and directors' liability insurance policies which
provide coverage against judgments, settlements and legal costs incurred because
of actual or asserted acts or omissions of such officers and directors of Summit
arising out of their duties as such, subject to certain  exceptions,  including,
but not limited to, damages based upon illegal  personal  profits or adjudicated
dishonesty of the person seeking indemnification.  The policies provide coverage
of $50,000,000 in the aggregate.

ITEM 22. UNDERTAKINGS.

      (a) The undersigned  registrant  hereby  undertakes  that, for purposes of
determining  any liability  under the Securities Act of 1933, each filing of the
registrant's  annual  report  pursuant to Section  13(a) or Section 15(d) of the
Securities  Exchange  Act of 1934  (and,  where  applicable,  each  filing of an
employee  benefit  plan's  annual  report  pursuant  to  Section  15(d)  of  the
Securities  Exchange  Act of 1934)  that is  incorporated  by  reference  in the
registration  statement  shall  be  deemed  to be a new  registration  statement
relating to the securities offered therein,  and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.

<PAGE>

     (b)  The undersigned registrant hereby undertakes:

          (1) To file,  during  any  period  in which  offers or sales are being
      made, a post-effective amendment to this registration statement:

              (i) To include any prospectus  required by section 10(a)(3) of the
                  Securities Act of 1933;

             (ii) To  reflect  in the  prospectus  any facts or  events  arising
                  after the effective date of the registration statement (or the
                  most   recent   post-effective   amendment   thereof)   which,
                  individually  or in the  aggregate,  represent  a  fundamental
                  change  in the  information  set  forth  in  the  registration
                  statement;

            (iii) To include any material information with  respect to the  plan
                  of distribution  not previously  disclosed in the registration
                  statement or any material  change to such  information  in the
                  registration statement;

                  PROVIDED, HOWEVER, that paragraphs (a)(1)(i) and (a)(1)(ii) of
                  this section do not apply if the registration  statement is on
                  Form S-3, Form S-8 or Form F-3, and the  information  required
                  to  be  included  in  a  post-effective   amendment  by  those
                  paragraphs  is  contained  in periodic  reports  filed with or
                  furnished  to the  Commission  by the  registrant  pursuant to
                  section 13 or section 15(d) of the Securities  Exchange Act of
                  1934 that are  incorporated  by reference in the  registration
                  statement.

           (2)  That, for the purpose of determining any liability under the
                Securities Act of 1933, each such post-effective amendment shall
                be deemed to be a new registration statement relating to the
                securities offered therein, and the offering of such securities
                at that time shall be deemed to be the initial bona fide
                offering thereof.

           (3)  To remove from registration by means of a post-effective
                amendment any of the securities being registered which remain
                unsold at the termination of the offering.

      (c)  Insofar  as  indemnification   for  liabilities   arising  under  the
Securities Act of 1933 may be permitted to directors,  officers and  controlling
persons of the  registrant  pursuant to the  provisions set forth in response to
Item 20 hereof,  or  otherwise,  the  registrant  has been  advised  that in the
opinion of the  Securities  and  Exchange  Commission  such  indemnification  is
against public policy as expressed in the Act and is, therefore,  unenforceable.
In the event that a claim for  indemnification  against such liabilities  (other
than the payment by the  registrant of expenses  incurred or paid by a director,
officer or controlling person of the registrant in the successful defense of any
action, suit or proceeding) is asserted by such director, officer or controlling
person in connection with the securities being registered,  the registrant will,
unless in the opinion of its counsel the matter has been settled by  controlling
precedent, submit to a court of appropriate jurisdiction the question of whether
such  indemnification by it is against public policy as expressed in the Act and
will be governed by the final adjudication of such issue.

      (d) The undersigned  registrant  hereby  undertakes to respond to requests
for information  that is incorporated by reference into the prospectus  pursuant
to Items 4, 10(b), 11 or 13 of this Form,  within one business day of receipt of
such  request,  and to send the  incorporated  documents  by first class mail or
other equally  prompt means.  This includes  information  contained in documents
filed subsequent to the effective date of the registration statement through the
date of responding to the request.

      (e) The undersigned  registrant  hereby undertakes to supply by means of a
post-effective  amendment  all  information  concerning a  transaction,  and the
company  being  acquired  involved  therein,  that  was not the  subject  of and
included in the registration statement when it became effective.

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

Gentlemen:

This opinion is given in connection with Registration Statement No. 333-93515 on
Form S-4 (the "Registration Statement") filed by Summit Bancorp. (the "Company")
with the Securities and Exchange Commission under the Securities Act of 1933, as
amended,  with respect to up to 2,948,741  shares of the Company's Common Stock,
par value $.80 per share (the "Common Shares"),  to be issued to shareholders of
NMBT  Corp.  ("NMBT")  in  connection  with the merger of NMBT with and into the
Company  (the  "Merger"),  pursuant  to an  Agreement  and Plan of Merger  dated
October 3, 1999 (the "Merger Agreement").

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

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

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

                                                        Very truly yours,

                                                        /s/ Richard F. Ober, Jr.

Ladies and Gentlemen:

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

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

                  (i) The Agreement and Plan of Merger  between  Summit and NMBT
                  dated  October 3, 1999,  including  the schedules and exhibits
                  thereto (the "Agreement"),  and the "Reorganization  Election"
                  (as the quoted term is defined in the Agreement);

                  (ii) Summit's  Registration  Statement on Form S-4,  including
                  the Proxy  Statement/Prospectus  contained therein, filed with
                  the Securities  and Exchange  Commission on December 23, 1999,
                  as   supplemented   and   amended  to  the  date  hereof  (the
                  "Registration Statement");

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

                  (iv)   The    representations   and   undertakings   of   NMBT
                  substantially in the form of Exhibit B hereto; and

                  (v) The  Shareholder  Rights  Plan  between  Summit  and First
                  Chicago Trust  Company of New York, as rights agent,  dated as
                  of June 16, 1999 (collectively, the "Rights Agreements").

                  Our  opinion  is  based  solely  upon  applicable  law and the
factual information and undertakings contained in the above-mentioned documents.
In rendering our opinion,  we have assumed the accuracy of all  information  and
the performance of all undertakings contained in each of such documents,  and we
have assumed  that all  representations  made to the  knowledge of any person or
entity or with similar qualification will be true and correct as if made without
such  qualification.  We also have  assumed  the  authenticity  of all  original
documents,  the  conformity  of all copies to the  original  documents,  and the
genuineness of all signatures. We have not attempted to verify independently the
accuracy of any information in any such document,  and we have assumed that such
documents  accurately  and  completely  set forth all material facts relevant to
this opinion. All of our assumptions were made with your consent. If any fact or
assumption  described  herein or below is  incorrect,  any or all of the federal
income tax consequences described herein may be inapplicable.

                                     OPINION

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

                  1. The Merger  will  constitute  a  reorganization  within the
meaning of section 368(a)(1) of the Internal Revenue Code of 1986, as amended to
the date  hereof  (the  "Code").  Each of Summit  and NMBT will be a "party to a
reorganization" within the meaning of Section 368(b) of the Code.

                  2. Each  shareholder  of NMBT who  exchanges,  in the  Merger,
shares of NMBT common  stock,  par value $0.01 per share ("NMBT  Common  Stock")
solely for shares of Summit common stock,  par value $0.80 per share,  including
the rights  associated  therewith  under the Rights  Agreements  ("Summit Common
Stock"):

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

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

                           c) will  have a  holding  period  for the  shares  of
                  Summit Common Stock received  (including any fractional  share
                  of Summit Common Stock deemed to be

                  received,  as described in paragraph 3, below) which  includes
                  the  holding  period  of  the  shares  of  NMBT  Common  Stock
                  surrendered,  provided  that the shares of NMBT  Common  Stock
                  surrendered  are  held as  capital  assets  at the time of the
                  Merger (Code section 1223(1)).

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

                            * * * * * * * * * * * *

                  We express no opinion  with regard to: (1) the federal  income
tax  consequences  of the  Merger  not  addressed  expressly  by  this  opinion,
including  without  limitation,  (i) the tax  consequences,  if  any,  to  those
shareholders  of NMBT who acquired  shares of NMBT Common Stock  pursuant to the
exercise of employee  stock options or otherwise as  compensation,  and (ii) the
tax consequences to special classes of shareholders,  if any,  including without
limitation,   foreign  persons,   insurance   companies,   tax-exempt  entities,
retirement plans, and dealers in securities;  and (2) federal,  state, local, or
foreign  taxes  (or any  other  federal,  state,  local,  or  foreign  laws) not
specifically  referred to and discussed  herein.  Further,  our opinion is based
upon the Code,  Treasury  Regulations  proposed or promulgated  thereunder,  and
administrative  interpretations and judicial precedents relating thereto, all of
which are subject to change at any time,  possibly with retroactive  effect, and
we assume no obligation to advise you of any subsequent change thereto. If there
is any  change  in the  applicable  law or  regulations,  or if there is any new
administrative or judicial  interpretation of the applicable law or regulations,
any or all of the federal income tax  consequences  described  herein may become
inapplicable.

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

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

                                                Very truly yours,
