Dear Fellow Shareholder:

     We are  pleased to enclose  information  relating  to a Special  Meeting of
Shareholders  of NSS  Bancorp,  Inc.  to be held at Norwalk  Inn and  Conference
Center, Norwalk, Connecticut, at 10:00 a.m. local time on 1998.

     At the  Special  Meeting,  you will be asked to  approve  a  Reorganization
Agreement  dated June 17,  1998 by and between  NSS and Summit  Bancorp.,  a New
Jersey-based  bank  holding  company.  Under  the  terms  of the  Reorganization
Agreement,  Summit will acquire all of the issued and outstanding  shares of NSS
common stock in exchange for the right to receive  1.232 shares of Summit common
stock for each exchanged share of NSS common stock (and cash,  without interest,
in lieu of fractional shares) (the  "Reorganization").  You are also being asked
to vote on a proposal  to adjourn  the  Special  Meeting if  required to solicit
additional votes.

     You will have the  opportunity to participate as a shareholder in Summit if
NSS  shareholders  approve  the  Reorganization.   We  believe  that  NSS,  upon
completion  of the  strategic  alliance  with  Summit,  will be able to  offer a
broader variety of products and services . We likewise  believe that,  after the
Reorganization,  Summit  will be well  positioned  to  achieve  NSS's  goals for
community service, continued revenue growth and improved profitability, customer
service, and shareholder returns.

     YOUR  BOARD  OF  DIRECTORS  HAS  UNANIMOUSLY  APPROVED  THE  AGREEMENT  AND
UNANIMOUSLY  RECOMMENDS  THAT  YOU  VOTE  FOR  APPROVAL  OF  THE  REORGANIZATION
AGREEMENT AND THE CONSUMMATION OF THE  TRANSACTIONS  CONTEMPLATED  THEREBY.  The
enclosed Proxy Statement-Prospectus explains in detail the terms of the proposed
Reorganization and related matters.  Please carefully review and consider all of
this information.

     Consummation  of the  Reorganization  is  subject  to  certain  conditions,
including  the  approval  of the  Reorganization  by the  requisite  vote of NSS
Shareholders  and  approval of the  Reorganization  by various  bank  regulatory
authorities.

     It is very  important  that your  shares  are  represented  at the  Special
Meeting,  whether or not you plan to attend in person. The affirmative vote of a
majority of the holders of the  outstanding  shares of NSS common stock entitled
to vote is required for approval of the Reorganization. Your failure to vote for
approval of the  Reorganization  will have the same effect as a vote against the
Reorganization.   The  approval  of  any  proposed   adjournment   requires  the
affirmative vote of a majority of the votes cast by holders of NSS common stock,
provided that at least 50% of the  outstanding  shares are represented in person
or by proxy.  IN ORDER TO ENSURE  THAT YOUR VOTE IS  REPRESENTED  AT THE SPECIAL
MEETING, PLEASE SIGN, DATE AND MAIL THE PROXY CARD IN THE ENCLOSED ENVELOPE. You
are, of course, welcome to attend the meeting and to vote your shares in person.

                              NSS SPECIAL MEETING

TIME, DATE, PLACE AND PURPOSE

     The Special  Meeting will be held on __________,  1998 at _____ a.m. (local
time), in the  _______________________________________Norwalk,  Connecticut,  to
consider  and vote upon (1) a proposal to approve the  Reorganization  Agreement
and the transactions  contemplated thereby,  including the Reorganization Option
Agreement and (2) a proposal to approve the Adjournment  Proposal. A copy of the
Reorganization Agreement is attached hereto as Appendix A.


RECORD DATE, VOTE REQUIRED

     The record date ("Record Date") for determining NSS  shareholders  entitled
to notice of and to vote at the  Special  Meeting is  September  __,  1998.  The
presence, in person or by proxy, of at least a majority of the __________ shares
of NSS Common outstanding on the Record Date is necessary to constitute a quorum
at the Special Meeting.  Assuming a quorum is present,  an affirmative vote of a
majority of the votes  entitled to be cast by the holders of shares  entitled to

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

                                       1

proposal  than  against.  In the  event a quorum  is not  present  or there  are
insufficient votes to approve any proposal, the Special Meeting may be adjourned
from time to time by a majority of those  present in person or by proxy in order
to permit, as appropriate, further solicitation of proxies by the NSS Board.


                          STOCK HELD BY NSS AFFILIATES

     The  directors  and  executive   officers  of  NSS  and  their   affiliates
beneficially  owned,  as of the  Record  Date,  ________  shares  of NSS  Common
(assuming  the  exercise  of all  options to  purchase  NSS Common  held by such
persons and  outstanding on such date),  representing  ____% of the  outstanding
shares of NSS Common.  The directors and executive  officers of NSS have entered
into  agreements  with Summit to vote their shares of NSS Common in favor of the
proposal to approve the Reorganization Agreement.


     Summit  beneficially owns 105,500 shares of NSS Common,  which represents %
of the  outstanding  shares of NSS Common,  and intends to vote these  shares in
favor of the proposal to approve the Reorganization Agreement.

     Also, by virtue of holding the NSS Option (as defined herein), Summit could
be deemed to be the  beneficial  owner of an  additional  494,629  shares of NSS
Common.  Combined,  the 105,500 shares beneficially owned and the 494,629 shares
deemed beneficially owned by Summit represent % of NSS Common outstanding on the
Record Date (assuming,  for purposes of calculating  this  percentage,  that the
shares  represented by the NSS Option were issued and outstanding on such date).
However,  the NSS  Option  is not  presently  exercisable  and  the  NSS  Common
represented thereby has not been issued, is not outstanding and cannot be voted.



                               THE REORGANIZATION

EFFECTIVE TIME

     The  Reorganization  will  become  effective  at the  hour  and on the date
("Effective  Time")  specified  in the  certificate  or  certificates  of merger
required to be filed with the  jurisdictions or jurisdiction of incorporation of
each  of  the  constituent  corporations  to  the  Reorganization,   or  if  the
Reorganization  is effected  as a share  exchange  pursuant  to the  Connecticut
Business  Corporation  Act  ("CBCA"),   the  time  and  date  specified  in  the
certificate of exchange filed with the Secretary of State of Connecticut. If the
Reorganization is approved by NSS  shareholders,  subject to the satisfaction or
waiver of certain other conditions set forth in the Reorganization Agreement, it
is currently  contemplated  that the Effective Time will occur during the fourth
calendar quarter of 1998. See "THE REORGANIZATION-Closing and Effective Time."


CONVERSION OF NSS COMMON

     At the Effective Time,  outstanding shares of NSS Common, other than shares
of NSS Common beneficially owned by Summit or a subsidiary of Summit (other than
shares  of NSS  Common  held as a result  of  foreclosures  or debts  previously
contracted),  if  any,  shares  of NSS  Common  beneficially  owned  by NSS or a
subsidiary  of NSS  (other  than  shares  of NSS  Common  held  as a  result  of
foreclosures  or debts  previously  contracted),  if any, and shares held in the
treasury of NSS,  if any,  will be  converted  into and  represent  the right to
receive the  Reorganization  Consideration.  Within 10 days of the receipt of an
accurate  and  complete  list of all  holders  of record of NSS Common as of the
Effective  Time by First Chicago  Trust  Company of New York, or another  entity
reasonably   satisfactory   to  NSS,  acting  as  the  exchange  agent  for  the
Reorganization ("Exchange Agent"), from NSS, each holder of record of NSS Common
will be sent by the Exchange Agent  information  regarding,  and materials to be
used in, the  exchange  of NSS Common for Summit  Common.  Within 10 days of the
later  to occur  of the  receipt  of a final  shareholder  list  from NSS by the
Exchange  Agent  or the  receipt  by the  Exchange  Agent of  complete  exchange
materials from a NSS shareholder,  the NSS shareholder will be sent, in exchange
for all certificates  representing their NSS Common ("NSS Common Certificates"),
one certificate  representing the whole shares of Summit Common into which their
NSS Common has been converted  ("Summit Common  Certificate") and, to the extent
entitled thereto, a check representing the Cash In Lieu Amount. Such exchange

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

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

period may be  extended 5 business  days by the  Exchange  Agent to permit it to
satisfy its obligations under the Internal Revenue Code of 1986, as amended (the
"Code"), with respect to reporting the dividend income.


CONVERSION OF NSS STOCK OPTIONS


     Each stock option relating to NSS Common ("Original Option") outstanding at
the  Effective  Time and granted to a director  or employee  pursuant to the NSS
1994 Director Stock Option Plan (the  "Director  Plan") or the NSS 1994 Employee
Stock Option Plan (the "Employee Plan")  (collectively,  the "NSS Option Plans")
will be converted automatically at the Effective Time into an option to purchase
Summit Common ("New  Option").  All Original  Options granted under the Employee
Plan,  whether or not exercisable  immediately prior to the Effective Time, will
be converted  pursuant to the terms of the Employee  Plan into a New Option that
is immediately  exercisable after the Effective Time and for a thirty day period
holders  of such  options  may  elect to  receive  a cash  payment  equal to the
difference  between  the  adjusted  exercise  price and the value of the  Summit
Common that could be obtained  upon the  exercise of the option.  Subject to the
adjustment in exercise price and the number of shares  described  below, the New
Options will continue to be governed by the terms of the NSS Option Plan and the
stock option agreement  pursuant to which the corresponding  Original Option was
granted,  including  terms and  provisions  governing  exercises.  The number of
shares of Summit Common subject to the New Options and the exercise price of the
New Options will be adjusted as provided in the  Reorganization  Agreement based
on the Exchange  Ratio.  See "THE  REORGANIZATION-Conversion  of Stock Options."


RECOMMENDATION OF NSS BOARD

     The NSS Board unanimously  recommends that NSS shareholders vote to approve
the   Reorganization   Agreement  and  the   Adjournment   Proposal.   See  "THE
REORGANIZATION-Recommendation of NSS Board."


OPINION OF NSS'S FINANCIAL ADVISOR


     NSS engaged Sandler O'Neill & Partners,  L.P. ("Sandler O'Neill") to act as
financial  advisor in connection with any acquisition of or by NSS and to render
its opinion to the NSS Board as to whether the  Exchange  Ratio is fair,  from a
financial  point  of view,  to the  shareholders  of NSS.  Sandler  O'Neill  has
delivered   to  NSS  an   opinion   dated   as  of  the   date  of  this   Proxy
Statement-Prospectus  stating  that,  as of such  date,  based on the review and
assumptions and subject to the limitations described therein, the Exchange Ratio
is  fair,  from a  financial  point of view,  to NSS's  shareholders.  A copy of
Sandler   O'Neill's   opinion  is   attached   as   Appendix  B  to  this  Proxy
Statement-Prospectus   and   should   be  read  in  its   entirety.   See   "THE
REORGANIZATION-Opinion of NSS's Financial Advisor." 


DISSENTERS' RIGHTS


     By complying  with the specific  procedures  required by the CBCA described
herein and  attached  hereto as Appendix D,  holders of NSS Common will have the
right to dissent from the Reorganization, in which event they may be entitled to
receive the "fair value" of their shares of NSS Common. See "THE  REORGANIZATION
- - Dissenters' Rights." 


ACCOUNTING TREATMENT

     It is  anticipated  that  the  Reorganization,  when  consummated,  will be
accounted for as a purchase. See "THE REORGANIZATION-Accounting Treatment."


FEDERAL INCOME TAX CONSEQUENCES


     Thompson Coburn, Summit's special counsel, has delivered its opinion to the
effect  that,  assuming  the  Reorganization   occurs  in  accordance  with  the
Reorganization   Agreement   and   conditioned   on  the   accuracy  of  certain
representations  made by Summit and NSS, the  Reorganization  will  constitute a
"reorganization" within 

- --------------------------------------------------------------------------------
                                       3

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

the  meaning of Section 368 of the  Internal  Revenue  Code of 1986,  as amended
("Code"), for federal income tax purposes and that, accordingly, no gain or loss
will be recognized by NSS  shareholders  who exchange their shares of NSS Common
solely for shares of Summit Common in the Reorganization, except with respect to
any Cash In Lieu  Amount  received,  if any.  Each NSS  shareholder  is urged to
consult his or her tax advisor to determine the specific tax consequences of the
Reorganization  to such  shareholder,  including  the  applicability  of various
state,  local,  and foreign tax laws. See "THE  REORGANIZATION-  Certain Federal
Income Tax Consequences of the Reorganization."


REGULATORY APPROVALS

     Consummation  of  the  Reorganization  requires,  and is  conditioned  upon
receipt  of,  approvals  by  the  Federal  Reserve  Board  and  the  Connecticut
Commissioner of Banking. See "THE REORGANIZATION-Regulatory Approvals."


CONDITIONS OF THE REORGANIZATION

     Consummation of the  Reorganization  is additionally  subject,  among other
things,  to (i) the  approval of the  Reorganization  Agreement by a majority of
NSS's  shareholders  entitled to vote on the matter;  (ii) the expiration of any
waiting  period  required  in  connection  with  a  regulatory  approval;  (iii)
continued  effectiveness of the registration  statement;  (iv) receipt by Summit
and NSS of the  opinion  of  Thompson  Coburn as to certain  federal  income tax
consequences  of the  Reorganization;  (v) the NYSE  having  indicated  that the
shares of Summit Common to be issued in the  Reorganization  are to be listed on
the NYSE  subject  to  official  notice of  issuance;  (vi) the  absence  of any
material litigation;  (vii) the absence of regulatory agreements relating to the
respective parties; and (viii) the delivery of officers' certificates by NSS and
Summit. Certain of the foregoing conditions may be waived by the party for whose
benefit the condition  was included.  However,  the  Reorganization  will not be
consummated   without  the  receipt  of  all   Required   Approvals.   See  "THE
REORGANIZATION-The  Reorganization  Agreement-Conditions  to the Reorganization,
Termination." 


TERMINATION

     The  Reorganization  Agreement may be  terminated by mutual  consent of the
Summit  Board  and the NSS  Board.  The  Reorganization  Agreement  may  also be
terminated  by  either  the  Summit  Board or the NSS  Board  if the  conditions
precedent to,  respectively,  Summit's or NSS's  obligations  to close under the
Reorganization   Agreement  have  not  been  met.  Further,  the  Reorganization
Agreement  may be  terminated by either the Summit Board or the NSS Board if (i)
the  shareholders  of NSS have  failed to  approve  the  Reorganization;  (ii) a
material breach by the other party of a warranty or  representation  or covenant
has  occurred  and has not been cured or is not capable of being cured (after 30
days notice  thereof has been given and provided that the  terminating  party is
not in  material  breach  of any  representation,  warranty,  covenant  or other
agreement);  or (iii) the Closing is not consummated on or before March 1, 1999.
In addition,  the NSS Board may  terminate the  Reorganization  Agreement if the
average  closing  price  of a share  of  Summit  Common  on the  NYSE  Composite
Transactions  List for the 10  consecutive  full trading days ending on the date
(the "FRB Approval Date") of the Required Approval given by the FRB (the "Summit
Price") is less than $39.11 and the number obtained by dividing the Summit Price
by  $47.125  is more than .17 less than the  number  obtained  by  dividing  the
average  closing  price  per  share  of the  common  stocks  of 18 bank  holding
companies (the "Index Group") for the 10 consecutive full trading days ending on
the FRB  Approval  Date by the  average  closing  price per share of the  common
stocks of the Index Group on June 16, 1998.  The Summit Board may  terminate the
Reorganization  Agreement  if the NSS Board fails to  recommend  approval of the
Reorganization  Agreement or withdraws  such  approval or if the cost of certain
environmental  matters  exceeds  thresholds  set  forth  in  the  Reorganization

INTERESTS OF CERTAIN PERSONS IN THE REORGANIZATION


     Directors   and   executive   officers  of  NSS  have   interests   in  the
Reorganization  that are in addition to their  interests as shareholders of NSS.
These  interests  include:  (1) the  indemnification  of directors and executive
officers of NSS against  certain  claims that may arise after the Effective Time
based  on  services  provided  to NSS  or any  subsidiary  of NSS  prior  to the
Effective  Time;  (2)  Summit's  covenant  to use its best  efforts to  purchase
insurance for six years after the Effective  Time,  subject to a maximum premium
limitation, protecting NSS directors and executive officers against such claims;
(3) the  conversion  of all Original  Options held by  directors  and  executive
officers of NSS into New Options,  with  adjustments  to the exercise  price and
number of shares subject thereto based on the Exchange Ratio,  and the immediate
exercisability,  pursuant  to the terms of the  Employee  Plan and stock  option
agreements,  of all New Options granted under the Employee Plan,  whether or not
the related  Original Option is exercisable  immediately  prior to the Effective
Time; (4) for Robert T. Judson, Charles F. Howell, Jeremiah T. Dorney and Marcus
I.  Braverman,  payments  of $  1,140,383,  $779,348,  $609,509,  and  $609,117,
respectively,  pursuant to their change of control  agreements with NSS; (5) for
Messrs.  Judson,  Howell, Dorney and Braverman,  payments of $135,041,  $92,001,
$72,000  and  $72,000,  respectively,  as  pro-rated  awards  under the NSS 1995
Executive  Incentive  Plan (the  "Executive  Incentive  Plan") and  payments  of
$92,840,  $63,250,  $49,500  and  $49,500,  respectively,  under the NSS  Annual
Incentive Plan (the  "Employee  Annual  Incentive  Plan") and (6) for Donald St.
John, Brian Fitzgerald,  Herbert Jay, Edward Kelley, John Segall and Alan Stack,
the  non-employee  directors  of NSS,  payments  of $25,300 to Mr. St.  John and
$16,400 to each other  non-employee  director as pro-rated  awards under the NSS
Directors  Annual  Incentive Plan (the "Director  Annual  Incentive  Plan",  and
together with the Employee Annual Incentive Plan the "Annual Incentive  Plans").
These  interests  and the  underlying  assumptions  are described in more detail
below   under  "THE   REORGANIZATION-Interests   of   Certain   Persons  in  the
Reorganization."


DIFFERENCE IN SHAREHOLDERS' RIGHTS


     The  rights  of NSS  shareholders,  which  are  determined  by  Connecticut
corporation law and the Certificate of Incorporation  and By-Laws of NSS, differ
from the rights accorded Summit shareholders, which are determined by New Jersey
corporation  law and the Restated  Certificate of  Incorporation  and By-Laws of
Summit.  Some of the  differences in  shareholders'  rights are  attributable to
differences  between  the  corporation  law of  Connecticut,  the state of NSS's
incorporation,  and the  corporation  law of New  Jersey,  the state of Summit's
incorporation. The remaining differences in shareholders rights are attributable
to differences  between the Certificate of Incorporation  and By-Laws of NSS and
the Restated Certificate of Incorporation and By-Laws of Summit.  Certain of the
rights of NSS shareholders which are provided by Connecticut  corporation law or
contained in the  Certificate of  Incorporation  or By-Laws of NSS and which are
not  provided  by New  Jersey  corporation  law  or  contained  in the  Restated
Certificate  of  Incorporation  or  By-Laws  of  Summit  are  deemed  to have an
anti-takeover  effect and will not be  available to NSS  shareholders  as Summit
shareholders; however, certain rights provided for by New Jersey corporation law
or the  Restated  Certificate  of  Incorporation  or  By-laws of Summit are also
deemed to have an anti-takeover effect and will be available to NSS stockholders
only after becoming Summit  shareholders.  See "THE REORGANIZATION - Differences
in Shareholders' Rights." 


REORGANIZATION OPTION AGREEMENT

     As an inducement  and condition to Summit's  willingness  to enter into the
Reorganization Agreement, NSS (as issuer) entered into the Reorganization Option
Agreement   with  Summit  (as  grantee),   dated  as  of  June  18,  1998.   The
Reorganization  Option  Agreement  is set  forth  in  Appendix  C to this  Proxy
Statement-Prospectus.


     Pursuant to the Reorganization  Option Agreement,  NSS granted to Summit an
irrevocable  option (the "NSS Option"),  exercisable  under certain  limited and
specifically defined  circumstances,  none of which, to the best of Summit's and
NSS's  knowledge,  has occurred as of the date hereof to purchase,  (a) prior to
the date the NSS shareholders have approved the Reorganization Option Agreement,
up to 248,308 shares of NSS Common,  at a price of $45.00 per share or (b) after
the date the NSS shareholders have approved the Reorganization Option 

- --------------------------------------------------------------------------------
                                       5


<PAGE>


Agreement,  up to  494,629  shares of NSS  Common  also at a price of $45.00 per
share. In addition,  NSS agreed to pay Summit a "breakup fee" of $3.5 million in
the event the NSS Option  becomes  exercisable  pursuant to the  conditions  set
forth in (a) above.


     The Reorganization  Option Agreement is intended to increase the likelihood
that the Reorganization will be consummated  according to the terms set forth in
the Reorganization  Agreement, and may be expected to discourage offers by third
parties  to acquire  NSS prior to the  Reorganization.  See "THE  REORGANIZATION
Reorganization Option Agreement." 


                          MARKET PRICES AND DIVIDENDS


     Summit Common is listed and traded on the NYSE under the symbol "SUB".  NSS
Common is listed and  traded on Nasdaq  under the  symbol  "NSSY"  (prior to the
October 1, 1997  formation of NSS, the common stock of NSS Bank traded on Nasdaq
under the same symbol).  The following table presents for the periods  indicated
(rounded  to the  nearest  cent and  adjusted  for all  stock  splits  and stock
dividends)  the high and low sale  prices of a share of Summit  Common  and of a

execution of the  Reorganization  Agreement),  and as of September  __, 1998 the
last sale price of a share of Summit  Common,  the last sale price of a share of

     NO ASSURANCE CAN BE GIVEN AS TO WHAT THE MARKET PRICE OF SUMMIT COMMON WILL
BE IF AND WHEN THE REORGANIZATION IS CONSUMMATED.  BECAUSE THE EXCHANGE RATIO IS
FIXED AND BECAUSE THE MARKET PRICE OF SUMMIT  COMMON IS SUBJECT TO  FLUCTUATION,
THE VALUE OF THE SHARES OF SUMMIT COMMON THAT HOLDERS OF NSS COMMON WILL RECEIVE
IN THE  REORGANIZATION  MAY  INCREASE OR  DECREASE  PRIOR TO AND  FOLLOWING  THE
REORGANIZATION. NSS SHAREHOLDERS ARE ADVISED TO OBTAIN CURRENT MARKET QUOTATIONS
FOR SUMMIT COMMON AND NSS COMMON. IN ADDITION, PAST DIVIDENDS PAID IN RESPECT OF
SUMMIT COMMON AND NSS COMMON ARE NOT NECESSARILY  INDICATIVE OF FUTURE DIVIDENDS
THAT MAY BE DECLARED AND PAID. NO ASSURANCE CAN BE GIVEN CONCERNING DIVIDENDS TO

      SUMMARY OF COMPARATIVE AND PRO FORMA PER SHARE FINANCIAL INFORMATION

     The  following  summary  presents,  for  the  periods  indicated,  selected
comparative and pro forma per share financial  information:  (i) on a historical
basis for both Summit and NSS;  (ii) on a pro forma  combined  basis for Summit,
giving effect to the  Reorganization;  and (iii) on a pro forma equivalent basis
per common share for NSS. Such financial  information is computed on a pro forma
equivalent  basis with respect to a share of NSS Common by  multiplying  the pro
forma  combined  amount (giving  effect to the  Reorganization)  by the Exchange
Ratio of 1.232.  The pro forma  information  does not reflect  anticipated  cost
savings expected to be realized from the Reorganization. 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 evaluation of
fair value, as of the close of the transaction. Therefore, the pro forma amounts
reflected in the pro forma per share  financial  information may differ from the
amounts  ultimately  determined.  The unaudited pro forma  information  does not
purport  to be  indicative  of the  combined  financial  position  or results of
operations of future periods.

                                  INTRODUCTION

     This Proxy  Statement-Prospectus  is being furnished to NSS shareholders as
of the Record Date in  connection  with the  solicitation  of proxies by the NSS
Board  for use at the  Special  Meeting  to be held  on  October__,  1998 or any
adjournments                             thereof,                             in
________________________________________________________,  Norwalk, Connecticut,
at _____a.m.,  Eastern Time.  The purpose of the Special  Meeting is to consider
and vote upon (i) a proposal to approve  the  Reorganization  Agreement  and the
transactions   contemplated   thereby,  and  (ii)  a  proposal  to  approve  the
Adjournment Proposal.


     THE NSS BOARD HAS APPROVED THE  REORGANIZATION  AGREEMENT  AND  UNANIMOUSLY
RECOMMENDS  THAT NSS  SHAREHOLDERS  VOTE FOR ITS  APPROVAL.  THE NSS BOARD  ALSO
RECOMMENDS THAT NSS SHAREHOLDERS VOTE FOR APPROVAL OF THE ADJOURNMENT PROPOSAL.




                                SPECIAL MEETING

RECORD DATE; VOTE REQUIRED; REVOCABILITY OF PROXIES

     The securities to be voted at the Special  Meeting consist of shares of NSS
Common,  with each share entitling its owner to one vote on each proposal and on
all other matters properly brought before the Special Meeting.  NSS had no other
class of outstanding  voting securities  entitled to vote on the  Reorganization
Agreement  or the  Adjournment  Proposal  at the close of business on the Record
Date. There were _____ holders of record of NSS Common and __________  shares of
NSS Common outstanding and eligible to be voted at the Special Meeting as of the
Record Date. It is anticipated  that this Proxy  Statement-Prospectus,  together
with the  enclosed  proxy  card,  will be  mailed  to  shareholders  on or about
September __, 1998.

     The presence at the Special Meeting,  in person or by proxy, of the holders
of at least a majority  of the shares of NSS  Common  outstanding  on the Record
Date will constitute a quorum for the  transaction of business.  By checking the
appropriate  box on the proxy card provided by the NSS Board, a shareholder  may
vote "FOR" approval of the Reorganization  Agreement, vote "AGAINST" approval of
the Reorganization Agreement or "ABSTAIN".  Under the CBCA and NSS's Certificate
of  Incorporation  and  By-Laws,  the  approval  of the  proposal to approve the
Reorganization  Agreement  requires  the  affirmative  vote of a majority of the
votes  entitled to be cast by the holders of shares  entitled to vote thereon at
the Special Meeting,  and the approval of the Adjournment Proposal requires that
more  votes  be cast  in  favor  of the  proposal  than  against  the  proposal.
Accordingly,  "broker non-votes" (i.e., shares held by brokers or nominees as to
which  instructions  have not been  received from the  beneficial  owners or the
persons  entitled  to vote such  shares and with  respect to which the broker or
nominee does not have discretionary voting power under the applicable NYSE rule)
will have the effect of a vote against the Reorganization  Agreement but have no
effect on whether  the  Adjournment  Proposal is  adopted.  Abstentions  will be
treated  as  shares  that are  present  and  entitled  to vote for  purposes  of
determining  the presence of a quorum and the number of votes necessary to adopt
any  proposal  and  therefore  will also have the effect of a vote  against  the
Reorganization Agreement.  Under NSS's Certificate of Incorporation the approval
of the Reorganization  Agreement requires only the vote of the majority of votes
entitled  to  be  cast  because  the  Reorganization   Agreement  meets  certain
conditions  set  forth  in  NSS's  Certificate  of  Incorporation  which  render
inapplicable  the  super  majority  voting  requirements  for  certain  business
combinations  set  forth  therein.  See  "THE  REORGANIZATION   -Differences  in
Shareholders Rights".  Proxies voting against the Reorganization  Agreement will
not be used by the proxy  holders to vote in favor of the  Adjournment  Proposal
unless the shareholder has voted FOR approval of the Adjournment Proposal on the
proxy card. The Special  Meeting may be adjourned from time to time if necessary
to  obtain  a  quorum  or  to  obtain  the  votes   necessary   to  approve  the
Reorganization  Agreement.  The approval of the Reorganization  Agreement by NSS
shareholders is a condition to the consummation of the Reorganization.  See "THE
REORGANIZATION-The  Reorganization  Agreement-Conditions  to the Reorganization;
Termination".

     If a quorum is not obtained,  or if fewer shares of NSS Common are voted in
favor of approval of the  Reorganization  Agreement than the number required for
approval,  it is expected  that, if a majority of the proxies voted with respect
to the  Adjournment  Proposal  have  been  voted  in  favor  of the  Adjournment
Proposal,  the Special Meeting will be postponed or adjourned for the purpose of
allowing additional time for obtaining  additional proxies or votes, and, at any
subsequent reconvening of the Special Meeting, all proxies will be voted in


                                       8


<PAGE>


the same manner as such proxies would have been voted at the original  convening
of  the  Special  Meeting  (except  for  any  proxies  which  have   theretofore
effectively  been revoked or  withdrawn).  As to other matters that may properly
come before the Special Meeting, unless otherwise provided in the Certificate of
Incorporation  or By-laws of NSS or by  statute,  the matter will be approved if
more votes are cast in favor of the matter than are cast against.


     If the enclosed  form of proxy is properly  executed and returned to NSS in
time to be voted at the Special Meeting,  the shares represented thereby will be
voted in  accordance  with the  instructions  marked  thereon.  Proxies that are
executed,  but as to which no instructions  have been marked,  will be voted FOR
the  approval  of the  Reorganization  Agreement  and  FOR the  approval  of the
Adjournment Proposal, except that if a proxy is voted against the Reorganization
Agreement  and no  instruction  is given  in  connection  with  the  Adjournment
Proposal,  the  proxy  will not be voted in favor of the  Adjournment  Proposal.
Should any other matter  properly come before the Special  Meeting,  the persons
named as proxies  in the  accompanying  proxy,  acting by a  plurality  of those
proxies present,  will have  discretionary  authority to vote on such matters in
accordance with their judgment.  As of the time of the preparation of this Proxy
Statement-Prospectus,  the NSS Board  does not know of any  matters  other  than
those  referred  to in the  Notice of  Special  Meeting  of  Shareholders  to be
presented for action at the Special Meeting. 

     Shareholders  who execute a proxy retain the right to revoke it at any time
prior to its use. Unless so revoked, the shares represented by such proxies will
be voted at the  Special  Meeting  and all  adjournments  thereof.  Prior to the
Special Meeting a proxy may be revoked by filing a written  revocation or a duly
executed  proxy  bearing a later date with the  Secretary  of NSS,  Jeremiah  T.
Dorney.  During the  Special  Meeting a proxy may be revoked by filing a written
revocation or a duly  executed  proxy bearing a later date with the secretary of
the Special Meeting prior to the close of voting. A proxy will not be voted if a
shareholder attends the Special Meeting and votes in person.

     If a shareholder  holds NSS Common through  participation in NSS's Employee
Stock Ownership Plan (the "NSS ESOP"),  the shareholder  will receive a separate
card for use in providing  voting  instructions  to the ESOP  Trustee.  The ESOP
Trustee will vote all allocated  shares held by the ESOP in accordance  with the
instructions received from participants and will vote all unallocated shares and
allocated  shares  with  respect  to  which  voting  instructions  have not been
received in its fiduciary discretion.

     Employees  who hold  NSS  Common  through  participation  in  NSS's  Thrift
Incentive  Savings  Plan ("NSS Thrift  Incentive  Plan") will receive a separate
card for use in providing  voting  instructions to the Trustee of the NSS Thrift
Incentive Plan. Full shares held by the NSS Thrift  Incentive Plan will be voted
by the Trustee in accordance with the instructions  received from  participants.
The  Trustee  will  vote  any   participants'   shares  with  respect  to  which
instructions have not been received in its fiduciary discretion.

     If a person  holding  NSS  Common  in street  name  wishes to vote such NSS
Common at the Special  Meeting,  the person must obtain from the nominee holding
the NSS Common in street name a properly executed "legal proxy"  identifying the
individual  as a NSS  shareholder,  authorizing  the NSS  shareholder  to act on
behalf of the  nominee at the  Special  Meeting  and  identifying  the number of
shares with respect to which the authorization is granted.

     The cost of soliciting  proxies will be borne by NSS. In addition to use of
the mails,  proxies may be solicited  personally or by telephone,  telecopier or
telegraph by officers,  directors or employees of NSS, who will not be specially
compensated for such solicitation activities.  Arrangements will also be made by
NSS to reimburse brokerage houses and other custodians, nominees and fiduciaries
for their reasonable  expense incurred in forwarding  solicitation  materials to
the beneficial owners of shares held of record by such persons. NSS has retained
Morrow & Co., a proxy soliciting firm, to assist in the solicitation of proxies,
at a fee of $6,000 plus fees for direct telephone solicitations,  if authorized,
and reimbursement of certain out-of-pocket costs.

                            SELECTED FINANCIAL DATA


     The tables below set forth selected  historical  financial  information for
Summit and NSS for each of the five years in the period ended  December 31, 1997
and the six  month  periods  ended  June  30,  1998  and  June  30,  1997.  Such

COORDINATION AND DETERMINATION OF DIVIDENDS UNDER REORGANIZATION AGREEMENT


     In order to ensure that NSS shareholders would be paid at least one, but no
more  than  one,   regular  dividend  in  the  calendar  quarter  in  which  the
Reorganization  is  consummated,  NSS  agreed  to  coordinate  with  Summit  the
declaration  of any dividends and the setting of any dividend  record or payment
dates. Under the Reorganization  Agreement, NSS may declare a quarterly dividend
up to $.13 per  share;  provided,  however,  that if Summit  declares a dividend
between the date of the  Reorganization  Agreement and the Effective  Time which
represents an increase over the most recent dividend declared by Summit prior to
the date of the  Reorganization  Agreement,  NSS may pay a dividend  per quarter
equal to $.13 plus the percentage increase in the Summit dividend.



DIVIDEND LIMITATIONS


     Summit's  primary source of funds to pay dividends to its  shareholders  is
provided by dividends from its subsidiary banks. The bank subsidiaries of Summit
are  restricted  by law in the amount of  dividends  they may pay to Summit.  In
addition,  Summit is  restricted  by certain  debt  agreements  in the amount of
dividends  it may pay to its  shareholders.  At June 30,  1998,  the amount that
would  have been  available  on that date for  dividend  payments  to holders of
Summit Common was approximately $106.7 million. 


              PROPOSAL I-APPROVAL OF THE REORGANIZATION AGREEMENT

                               THE REORGANIZATION

     The following  information  concerning  the  Reorganization,  insofar as it
relates to matters contained in the  Reorganization  Agreement,  is qualified in
its entirety by reference to the  Reorganization  Agreement,  a copy of which is
attached hereto as Appendix A and incorporated herein by reference.



GENERAL

     The  Reorganization  Agreement  provides for the reorganization of NSS with
and into Summit,  pursuant to one of the  following  methods,  as  determined by
Summit:  (1) The merger of NSS into  Summit;  (2) the merger of NSS into a newly
formed,  wholly-owned  subsidiary  of Summit;  (3) the merger of a newly formed,
wholly-owned  subsidiary  of Summit  into NSS or (4) the  exchange  of shares of
Summit Common for shares of NSS Common pursuant to the share exchange provisions
of the CBCA. Summit currently intends to effectuate the  Reorganization  through
the merger of NSS into Summit.  However, until the closing of the Reorganization
("Closing"),  Summit  has the  ability  to  select  any one of the four  methods
described above to effectuate the  Reorganization and may select from any of the
four methods without further notice to NSS shareholders.  Accordingly, a vote in
favor of the  Reorganization  Agreement  constitutes  approval to effectuate the
Reorganization pursuant to any one of the four methods described. In addition, a
vote  in  favor  of  the  proposal  to  approve  the  Reorganization   Agreement
constitutes  approval of the Reorganization  Option Agreement which is a part of
the  Reorganization  Agreement.  Upon  consummation of the  Reorganization,  and
irrespective  of the method chosen by Summit to effectuate  the  Reorganization,
each  outstanding  share of NSS  Common  other  than (i)  shares  of NSS  Common
beneficially  owned by Summit or a subsidiary  of Summit (other than shares held
as a result of foreclosures or debts previously contracted), if any, (ii) shares
of NSS Common  beneficially  owned by NSS or a  subsidiary  of NSS  (other  than
shares  of NSS  Common  held as a result  of  forfeitures  or  debts  previously
contracted), if any, and (iii) shares of NSS Common held in the treasury of NSS,
if any,  will  be  converted  into  and  represent  the  right  to  receive  the
Reorganization Consideration.



CLOSING AND EFFECTIVE TIME

     The  Reorganization  Agreement  provides that,  unless otherwise agreed and
assuming all  conditions to closing have been  satisfied or waived,  the Closing
will be held on the date  designated  by Summit on at least five  business  days
notice ("Closing  Notice") given to NSS. The date for the Closing  designated by
Summit may not be later  than 32 days after the last to occur of the  following:
(1) if the transactions  contemplated by the Reorganization  Agreement are being
contested in any legal proceedings, the date that all such proceedings have been


                                       13


<PAGE>


brought to a  conclusion  favorable,  in the  judgment of Summit and NSS, to the
consummation of the transactions contemplated by the Reorganization Agreement or
such prior date as Summit and NSS shall elect,  whether or not such  proceedings
have  been  brought  to a  conclusion;  or (2) the  date on which  all  Required
Approvals are received and any required waiting periods have expired.

     If the  Reorganization  Agreement is approved by the requisite  vote of NSS
shareholders, all other conditions of the Reorganization are satisfied or waived
and the Closing is held, the  Reorganization  will become  effective at the date
and time specified in the  certificate or  certificates of merger required to be
filed with the  jurisdiction or  jurisdictions  of  incorporation of each of the
constituent  corporations to the  Reorganization  or if the  Reorganization is a
share  exchange  the date and time  specified  in the  certificate  of  exchange
required to be filed with the Secretary of the State of the State of Connecticut
following the date on which the closing of the  Reorganization  occurs ("Closing
Date"). If the  Reorganization  Agreement is approved by NSS shareholders on the
scheduled date of the Special Meeting,  subject to the satisfaction or waiver of
certain other conditions described herein, it is presently contemplated that the
Effective  Time will  occur  during  the fourth  calendar  quarter of 1998.  The
Reorganization  Agreement  may be  terminated  by either  party if,  among other
things,  the Closing fails to occur on or before March 1, 1999,  but a party may
not  exercise  this right if the failure to close is due solely to that  party's
failure  to  perform  or  observe  agreements  required  by  the  Reorganization
Agreement to be performed or observed by it on or before the Closing  Date.  See
"THE  REORGANIZATION  --  The  Reorganization  Agreement  --  Conditions  to the
Reorganization; Termination".


CONVERSION OF NSS COMMON

     Upon  consummation of the  Reorganization,  the  outstanding  shares of NSS
Common held at the Effective  Time by each  shareholder  of NSS at the Effective
Time,  other  than (i) shares of NSS  Common  beneficially  owned by Summit or a
subsidiary  of Summit  (other than shares  held as a result of  foreclosures  or
debts  previously  contracted),  if any, (ii) shares of NSS Common  beneficially
owned by NSS or a  subsidiary  of NSS (other than shares of NSS Common held as a
result of forfeitures or debts previously contracted),  if any, and (iii) shares
of NSS Common held in the treasury of NSS, if any, will be converted into Summit
Common at  Exchange  Ratio of 1.232 and  represent  the right of the  particular
shareholder  to receive the whole  shares of Summit  Common  resulting  from the
conversion and, in lieu of any fractional  share of Summit Common resulting from
the  conversion,  a Cash in Lieu Amount  equal to the  fraction of a whole share
represented by the fractional  share  multiplied by the closing price of a share
of Summit Common on the NYSE-Composite Transactions List on the last trading day
prior to the  Effective  Time.  The  Exchange  Ratio is subject  to  appropriate
adjustments in the event that, from the date of the Reorganization  Agreement to
the Effective  Time,  the  outstanding  shares of Summit Common are increased or
decreased, changed into or exchanged for a different number or kind of shares or
securities through  reorganization,  recapitalization,  reclassification,  stock
dividend, stock split or reverse stock split or other similar changes. 


EXCHANGE OF NSS CERTIFICATES

     Prior to the  Effective  Time,  Summit will  appoint  First  Chicago  Trust
Company  of New York or another  entity  reasonably  satisfactory  to NSS as the
Exchange Agent.  As promptly as practicable  after the Effective Time, but in no
event  more than 10 days after the  Exchange  Agent  receives  an  accurate  and
complete  list of all  holders  of record of  outstanding  NSS  Common as of the
Effective  Time,  Summit  will  cause  the  Exchange  Agent  to send to each NSS
shareholder a letter of transmittal and  instructions  for exchanging  their NSS
Certificates  for a  Summit  Certificate  and,  if  entitled  thereto,  a  check
representing a Cash In Lieu Amount.

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


                                       14


<PAGE>


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

     Neither  certificates  for  fractions of shares of Summit  Common nor scrip
certificates for such fractions will be issued,  and holders of NSS Certificates
who would otherwise be entitled to receive  fractions of shares of Summit Common
will  have  none  of the  rights  with  respect  to  such  fractions  of  shares
(including, without limitation, the right to receive dividends) that a holder of
a full share of Summit Common would  possess in respect of such full share,  and
will receive, in lieu thereof, the Cash In Lieu Amount.

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

     NSS  SHAREHOLDERS  SHOULD NOT SURRENDER THEIR NSS CERTIFICATES FOR EXCHANGE
UNTIL A LETTER OF  TRANSMITTAL,  INSTRUCTIONS  AND OTHER EXCHANGE  MATERIALS ARE
RECEIVED FROM THE EXCHANGE AGENT.  HOWEVER, NSS SHAREHOLDERS ARE URGED TO NOTIFY
CHASEMELLON  SHAREHOLDER  SERVICES,  L.L.C.  NOW, AT (800) 851-9677 IF THEIR NSS
CERTIFICATES ARE LOST, STOLEN, DESTROYED OR NOT PROPERLY REGISTERED, IN ORDER TO
BEGIN THE PROCESS OF ISSUING REPLACEMENT NSS CERTIFICATES.


CONVERSION OF NSS STOCK OPTIONS


     Each  Original  Option  granted  pursuant to the NSS Option  Plans which is
outstanding   and   unexercised  at  the  Effective   Time,  will  be  converted
automatically  at the  Effective  Time into a New Option.  All Original  Options
granted under the Employee Plan, whether or not exercisable immediately prior to
the Effective Time, will be converted pursuant to the terms of the Employee Plan
into a New Option that is immediately  exercisable  after the Effective Time. In
addition,  for a thirty day period holders of New Options which were  originally
granted under the Employee  Plan have the right to elect to receive,  in lieu of
Summit  Common,  a cash  payment  equal to the  difference  between the adjusted
exercise  price of the New Option and the value of the Summit Common which could
be  acquired  pursuant  to  the  exercise  of the  New  Option.  Subject  to the
adjustment in exercise  price and number of shares,  described  below,  each New
Option  will  continue  to be governed by the terms of the NSS Option Plan under
which the  corresponding  Original  Option  was  granted  and the  stock  option
agreement by which it was evidenced,  including  terms and provisions  governing
exercises.  In each case,  (i) the number of shares of Summit Common  subject to
the New  Option  will be equal to the  number of shares of Summit  Common  which
would have been issued in the Reorganization if the shares of NSS Common subject
to that option were issued and  outstanding  immediately  prior to the Effective
Time, rounded down to the next lower full share, and (ii) the exercise price per
share of Summit  Common  subject to the New Option will be equal to the exercise
price  per share of NSS  Common  subject  to the  Original  Option so  converted
divided by the Exchange Ratio. 

     Within 45 days after the receipt by Summit of an accurate and complete list
of all holders of NSS options,  Summit will issue to each holder of New Options,
upon receipt and  cancellation  of all agreements  under which Original  Options
were issued to such holder,  appropriate  instruments  confirming the conversion
described above;  provided,  however, that Summit will not be obligated to issue
such  confirming  instruments  or any  shares of  Summit  Common  issuable  upon
exercise  of a New  Option  until  the  shares of Summit  Common  issuable  upon
exercise  of the New  Options  have  been  registered  with the  Commission  and
authorized  for  listing  on the  NYSE  and for  sale by any  appropriate  state
securities  regulators,  which Summit will use its best efforts to effect within
30  days  after  NSS  shall  have  delivered  to  Summit  the  above   mentioned
option-holder list.


RECOMMENDATION OF NSS BOARD

     THE  REORGANIZATION  AGREEMENT HAS BEEN APPROVED BY THE NSS BOARD.  THE NSS
BOARD  BELIEVES  THAT  THE  REORGANIZATION  IS IN  THE  BEST  INTERESTS  OF  NSS
SHAREHOLDERS.  THE NSS BOARD  UNANIMOUSLY  RECOMMENDS THAT NSS SHAREHOLDERS VOTE
FOR THE PROPOSAL TO APPROVE THE REORGANIZATION AGREEMENT.


                                       15

BACKGROUND


     NSS Bank completed its  conversion  from a mutual savings bank to a capital
stock savings bank in June,  1994. The Certificate of  Incorporation of NSS Bank
and Connecticut  Banking Department  regulations placed certain  restrictions on
the ability of a person to offer to acquire,  or acquire,  NSS Bank for a period
of three years following the conversion  (until June,  1997).  Shortly after the
expiration  of the  three  year  period,  NSS Bank and its  management  began to
receive, on occasion,  informal acquisition  proposals and other inquiries as to
NSS Bank's interest in forming a strategic alliance with another entity. The NSS
Bank  Board  determined  that none of these  informal  proposals  and  inquiries
warranted entering into formal negotiations with the party making them.

     Accordingly, NSS Bank concentrated most of its efforts in 1997 on improving
shareholder value as an independent institution.  NSS Bank formed NSS in 1997 to
provide  the  organization  with  a  greater  corporate  flexibility  to  effect
acquisitions,  stock repurchases and business and product expansion. However, in
considering  both the short-term and long-term  objectives of NSS, the NSS Board
recognized  that changes in  government  regulation  of  interstate  banking and
industry  consolidation had significantly  increased competition in NSS's market
area.  The NSS  Board  determined  that,  in order to  compete  in this  changed
environment,  NSS would  have to expand the  products  and  services  offered to
customers.

     During late 1997,  the NSS Board  interviewed  several  investment  banking
firms  specifically  to assist  NSS with its  evaluation  of  various  strategic
options to maximize shareholder value. Upon completion of the interview process,
NSS engaged Sandler O'Neill as its financial  advisor.  Sandler O'Neill reviewed
with NSS a variety of strategic  options,  including a possible  sale of NSS. At
that time, the NSS Board determined that it could enhance  shareholder  value by
remaining  independent,  improving operational  performance and repurchasing its
stock.

     Several  events  beginning  in  late  1997  and  carrying  over  into  1998
subsequently caused NSS to review its remaining independent  strategy.  First, a
significant  shareholder  of NSS publicly  took the position  that NSS should be
sold.  Second,  the stock price of NSS  appreciated  significantly  due in part,
presumably,  to the  increased  possibility  that NSS might be sold in the short
term.  Third,  a  number  of  banking  institutions  announced  acquisitions  at
historically high sales prices.  Finally, it became apparent through acquisition
announcements  such  as that  between  Citicorp  and  Travelers  Insurance  that
cross-industry  barriers were rapidly coming down,  thereby creating the promise
of a new and  powerful  competitive  force for  community  banks  such as NSS to
contend with.  After deliberate  consideration  of these  developments and NSS's
options, the NSS Board decided to further explore the possibility of a strategic
alliance with another financial institution.

     At the  instruction  of  NSS,  Sandler  O'Neill  identified  and  contacted
numerous financial institutions to determine their initial interest in acquiring
NSS. In May 1998,  Sandler O'Neill prepared a confidential  offering  memorandum
containing  financial data and other information  relating to NSS and sent it to
seven  companies  that  had  executed  confidentiality   agreements.  The  seven
companies were initially instructed to provide their preliminary  indications of
interest to Sandler  O'Neill by May 28, 1998.  Three of the seven companies that
received the offering memorandum provided  preliminary  indications of interest,
which  were  presented  to the NSS Board on June 3,  1998.  All three  proposals
contemplated  a stock- for- stock  exchange.  The NSS Board  questioned  Sandler
O'Neill  about the  financial  aspects  of each of the  proposals,  specifically
inquiring into the key financial components of comparable transactions.  The NSS
Board  dismissed one of the  indications of interest  because the Board believed
that the price  submitted  by that  bidder  was not  competitive.  The NSS Board
extensively  discussed the remaining two proposals,  and based upon the strength
of Summit's historic and expected results of operations, financial condition and
common stock value and the other factors  described below under "Reasons for the
Reorganzation",  NSS's Board determined  Summit to have the preferred  proposal.
The NSS Board then authorized Summit to perform additional due diligence on NSS,
asked Summit to prepare a definitive  agreement for review,  and  authorized its
representatives to perform certain due diligence  activities relative to Summit.
The NSS Board further  instructed Sandler O'Neill to advise the other interested
party that based upon the NSS Board's review of the other  proposals  submitted,
NSS had determined to pursue discussions with another party.

     In response to Sandler  O'Neill's  notification  the other interested party
submitted a revised proposal, increasing its price. Sandler O'Neill then advised
Summit that NSS had received a revised  proposal  from the other  finalist  that
would be considered by the NSS Board and suggested to Summit that it should


                                       16


<PAGE>


consider  revising  its  proposal  if it  intended  to  continue  to pursue  the
transaction.  In  response,  Summit  submitted  to NSS a revised  proposal  that
included an increase in the Exchange Ratio to 1.232 and reflected the completion
of Summit's due diligence  process.  NSS management,  its financial  advisor and
legal  counsel  proceeded  to review and revise  several  drafts of the proposed
agreement  with  Summit,  arriving at a draft  that was  presentable  to the NSS
Board for its consideration.  The proposed definitive agreement, together with a
memorandum  from NSS's  legal  counsel  summarizing  the  material  terms of the
definitive  agreement,  were then delivered to each of NSS's directors for their
review and consideration at the June 17, 1998 NSS Board meeting.

     At the June 17,  1998 NSS  Board  meeting,  Sandler  O'Neill  reviewed  the
financial  terms of the two  revised  proposals.  Management  of NSS and Sandler
O'Neill  also  reviewed  with the NSS Board the  results of their due  diligence
review of Summit.  Legal counsel for NSS reviewed at length with NSS's Board the
proposed  definitive  agreement  and  the  stock  option  agreement.   Based  on
substantially  the same  factors that led to its prior  decision,  plus the fact
that  Summit's  proposal was not  conditional  on due  diligence  review and was
embodied in a definitive  agreement,  NSS's Board again determined that Summit's
proposal,  with its increased price,  continued to be the preferred proposal. In
reaching its  determination  the NSS Board  considered  the  strengths of Summit
referenced  above, as well as other relevant  interests,  including those of the
shareholders, employees, customers, suppliers and community as required pursuant
to Connecticut  corporation law, and Sandler O'Neill's opinion that the Exchange
Ratio is fair to NSS's  shareholders  from a  financial  point of view.  The NSS
Board  determined that the  Reorganization  is in the best interests of NSS, its
shareholders  and other  constituents,  and for the reasons set forth below, the
NSS Board  unanimously  approved the  Reorganization.  The NSS Board  authorized
management and NSS's representatives to finalize the definitive agreement.  Once
final  revisions were made to the definitive  agreement,  it was executed by NSS
and Summit on the evening of June 17, 1998.  Summit and NSS  publicly  announced
the Reorganization prior to the beginning of business on June 18, 1998.


REASONS FOR THE REORGANIZATION


NSS

     The NSS Board unanimously  recommends the approval of the Reorganization to
shareholders.  The terms of the transaction,  including the Exchange Ratio, were
the result of arm's-length  negotiations  between NSS and Summit.  The NSS Board
believes  that  the  Reorganization   will  enable  holders  of  NSS  Common  to
immediately   realize  increased  value  on  their  investment  in  NSS  and  to
participate in opportunities  for appreciation of Summit Common. In reaching its
determination  that  the  Reorganization  is in the  best  interests  of the NSS
shareholders,   and  recommending   that  the  NSS   shareholders   approve  the
Reorganization,  the NSS Board consulted with NSS management, as well as Sandler
O'Neill and its legal  advisors,  and  considered  a number of factors.  Without
assigning  any relative or specific  weights  thereto,  the  following  material
factors were considered by the NSS Board in reaching its determination:


   (a) the amount and form of the consideration offered by Summit in relation to
       the market value,  book value,  earnings per share, and dividend rates of
       NSS Common and the NSS Board's belief that of the alternatives available,
       the Reorganization  offered the greatest  opportunity for long-term value
       to the NSS shareholders;

   (b) the expectation that the Reorganization will be a tax-free transaction to
       NSS and its shareholders to the extent that they receive Summit Common in
       exchange for their shares;

   (c) Summit's  business,  results  of  operations,   prospects  and  financial
       condition and the  historical  and  potential  future value of the Summit
       Common and dividends paid thereon;

   (d) the potential  operating  efficiencies  and  financial  strength that the
       Reorganization would provide to the combined NSS-Summit organization, its
       customers,  depositors,  employees and the communities it serves, and the
       immediate and long-term effect that it would have on such  organization's
       ability to compete for new business;


   (e) that  the  combined  organization  would  be well  situated  to  offer an
       expanded  range of financial  services and the benefits to customers as a
       result thereof;



                                       17


<PAGE>


   (f) the favorable conditions to the Reorganization,  including the absence of
       a condition requiring pooling-of-interests accounting treatment;



   (g) the fact that the Reorganization Agreement is structured in such a manner
       to empower the shareholders as a group to decide whether or not to accept
       Summit's proposal to acquire NSS;



   (h) Sandler  O'Neill's  opinion  that the  Exchange  Ratio  is  fair,  from a
       financial point of view, to NSS  shareholders,  and the fact that Sandler
       O'Neill  has  confirmed  in writing its  opinion,  as of the date of this
       Proxy Statement Prospectus;



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


   (j) the current and prospective environment in which NSS 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;


   (k) the  advantages  and  disadvantages  of NSS  remaining as an  independent
       institution or affiliating with a larger institution; and


   (l) the general  structure of the  Reorganization  and the  compatibility  of
       management and business philosophy of Summit and NSS.


     THE NSS BOARD  UNANIMOUSLY  RECOMMENDS  THAT NSS  SHAREHOLDERS  VOTE  "FOR"
APPROVAL OF THE REORGANIZATION AGREEMENT.


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


OPINION OF NSS'S FINANCIAL ADVISOR


     Pursuant to an  engagement  letter dated as of April 20, 1998 (the "Sandler
O'Neill  Agreement"),  NSS retained Sandler O'Neill as an independent  financial
advisor  in  connection  with  NSS's   consideration  of  a  possible   business
combination  with a second  party.  Sandler  O'Neill is a nationally  recognized
investment  banking firm whose principal business specialty is banks and savings
institutions. In the ordinary course of its investment banking business, Sandler
O'Neill is  regularly  engaged in the  valuation  of such  businesses  and their
securities  in  connection  with mergers and  acquisitions  and other  corporate
transactions.


     Pursuant to the terms of the Sandler  O'Neill  Agreement,  Sandler  O'Neill
acted as financial  advisor to NSS in  connection  with the  Reorganization.  In
connection  therewith,  the NSS Board  requested  Sandler  O'Neill to render its
opinion as to the fairness of the Exchange Ratio to the shareholders of NSS from
a financial point of view. On June 17, 1998,  Sandler  O'Neill  delivered to the
NSS Board its oral opinion,  subsequently confirmed in writing, that, as of such
date,  the Exchange Ratio was fair to the holders of shares of NSS Common from a
financial  point of view.  Sandler O'Neill has also delivered to the NSS Board a
written opinion dated the date of this Proxy  Statement-Prospectus (the "Sandler
O'Neill Fairness Opinion") which is substantially identical to the June 17, 1998
opinion. THE FULL TEXT OF THE SANDLER O'NEILL FAIRNESS OPINION, WHICH SETS FORTH
THE PROCEDURES FOLLOWED, ASSUMPTIONS MADE, MATTERS CONSIDERED AND QUALIFICATIONS
AND  LIMITATIONS  ON THE REVIEW  UNDERTAKEN IN CONNECTION  WITH  RENDERING  SUCH
OPINION,  IS ATTACHED AS APPENDIX B TO THIS PROXY  STATEMENT-  PROSPECTUS AND IS
INCORPORATED  HEREIN BY  REFERENCE.  THE  DESCRIPTION  OF THE  OPINION SET FORTH
HEREIN IS  QUALIFIED  IN ITS  ENTIRETY BY  REFERENCE  TO APPENDIX B.  HOLDERS OF
SHARES OF NSS COMMON ARE URGED TO READ THE SANDLER O'NEILL  FAIRNESS  OPINION IN
ITS  ENTIRETY  IN   CONNECTION   WITH  THEIR   CONSIDERATION   OF  THE  PROPOSED
REORGANIZATION.


                                       18


<PAGE>


     THE SANDLER O'NEILL  FAIRNESS OPINION WAS PROVIDED TO THE NSS BOARD FOR ITS
INFORMATION  AND IS DIRECTED  ONLY TO THE  FAIRNESS,  FROM A FINANCIAL  POINT OF
VIEW,  OF THE  EXCHANGE  RATIO TO HOLDERS OF SHARES OF NSS  COMMON.  IT DOES NOT
ADDRESS THE UNDERLYING  BUSINESS DECISION OF NSS TO ENGAGE IN THE REORGANIZATION
OR  ANY  OTHER  ASPECT  OF  THE   REORGANIZATION   AND  DOES  NOT  CONSTITUTE  A
RECOMMENDATION  TO ANY HOLDER OF SHARES OF NSS COMMON AS TO HOW SUCH SHAREHOLDER
SHOULD VOTE AT THE SPECIAL  MEETING  WITH RESPECT TO THE  REORGANIZATION  OR ANY
OTHER MATTER RELATED THERETO.


     In connection  with  rendering its June 17, 1998 opinion,  Sandler  O'Neill
performed a variety of  financial  analyses.  The  following is a summary of the
material  analyses  performed by Sandler  O'Neill,  but does not purport to be a
complete  description of all the analyses  underlying Sandler O'Neill's opinion.
The preparation of a fairness opinion is a complex process involving  subjective
judgments and is not  necessarily  susceptible to a partial  analysis or summary
description.  Sandler O'Neill believes that its analyses must be considered as a
whole and that  selecting  portions of such analyses and the factors  considered
therein,   without  considering  all  factors  and  analyses,  could  create  an
incomplete  view of the  analyses  and  processes  underlying  its  opinion.  In
performing its analyses,  Sandler O'Neill made numerous assumptions with respect
to industry  performance,  business and economic  conditions  and various  other
matters,  many of which cannot be  predicted  and are beyond the control of NSS,
Summit and  Sandler  O'Neill.  Any  estimates  contained  in  Sandler  O'Neill's
analyses are not necessarily  indicative of future results or values,  which may
be  significantly  more or less favorable than such estimates.  Estimates on the
values of companies do not purport to be appraisals or  necessarily  reflect the
prices at which companies or their securities may actually be sold. Because such
estimates are inherently subject to uncertainty, neither Summit, NSS nor Sandler
O'Neill assumes responsibility for their accuracy.



SUMMARY OF PROPOSAL


     Sandler O'Neill  reviewed the financial terms of the proposed  transaction.
Based on the closing  price of Summit  Common on June 17, 1998 of $47.75 and an
Exchange Ratio of 1.232, Sandler O'Neill calculated an implied transaction value
per share of NSS of $58.83. Based upon such implied transaction value and NSS's
March 31, 1998 financial  information,  Sandler O'Neill  calculated the price to
tangible book value and price to last twelve months' normalized  earnings.  This
analysis yielded a price to tangible book value multiple of 2.64x and a price to
last twelve months' earnings multiple of 26.74x.



STOCK TRADING HISTORY

     Sandler  O'Neill  reviewed the history of the reported  trading  prices and
volume of NSS  Common  and  Summit  Common,  and the  relationship  between  the
movements  in the  prices of NSS  Common and  Summit  Common,  respectively,  to
movements in certain  stock  indices,  including the Standard & Poor's 500 Index
(the "S&P  Index"),  the NASDAQ  Banking Index (the "Bank Index") and a selected
composite group of publicly traded savings institutions (in the case of NSS) and
publicly traded commercial banks (in the case of Summit) in geographic proximity
and of similar asset size to NSS and Summit,  respectively.  During the one-year
period ended June 12, 1998, NSS Common outperformed each of the indices to which
it was compared,  and Summit Common  outperformed  each of the S&P Index and the
Bank Index and slightly under performed the peer group index.



COMPARABLE COMPANY ANALYSIS

     Sandler  O'Neill used publicly  available  information to compare  selected
financial and market trading  information,  including balance sheet composition,
asset quality ratios, loan loss reserve levels, profitability, capital adequacy,
dividends and trading multiples, for NSS and two groups of savings institutions.
The first group  consisted of NSS and the following 12 publicly  traded regional
savings  institutions (the "Regional  Group"):  Medford Bancorp Inc.,  BostonFed
Bancorp Inc.,  First Federal of East  Hartford,  MECH Financial  Inc.,  MASSBANK
Corp.,  People's Bancshares Inc., American Bank of Connecticut,  MetroWest Bank,
Abington Bancorp Inc., Bancorp Connecticut Inc., Warren Bancorp Inc., and NewMil
Bancorp Inc.  Sandler O'Neill also compared NSS to a group of 10 publicly traded
savings  institutions which had a return on average equity (based on last twelve
months'  earnings)  of greater  than 16% and a price to  tangible  book value of
greater than 230% (the


                                       19


<PAGE>


"Highly  Valued  Group").   The  Highly  Valued  Group  included  the  following
institutions:  Metropolitan  Financial  Corp.,  People's  Bancshares  Inc., CFSB
Bancorp Inc., Great Southern Bancorp Inc., Home Federal Bancorp, MetroWest Bank,
Coastal  Financial  Corp.,  PVF  CapitalCorp.,  Warren  Bancorp  Inc.  and First
Citizens Corp. The analysis compared publicly  available  financial  information
for NSS and the median data for each of the Regional Group and the Highly Valued
Group as of and for each of the years ended  December 31, 1993 through  December
31, 1997 and as of and for the twelve months ended March 31, 1998.

     Sandler  O'Neill  also used  publicly  available  information  to perform a
similar  comparison of selected  financial and market  trading  information  for
Summit and two different  groups of commercial  banks. The first group consisted
of Summit and the following  five publicly  traded  commercial  banks (the "Peer
Group"):  Bank of New York Co.,  Republic New York Corp.,  HSBC  Americas  Inc.,
First Maryland Bancorp and M&T Bank  Corporation.  Sandler O'Neill also compared
Summit to a group of eight publicly traded  commercial  banks which had a return
on average  equity (based on last twelve  months'  earnings) of greater than 18%
and a price to tangible book value of greater than 320% (the "Commercial  Highly
Valued Group"). The Commercial Highly Valued Group was comprised of State Street
Corp., Comerica Inc., Northern Trust Corp., Fifth Third Bancorp,  Firstar Corp.,
First Tennessee  National Corp., First Empire State Corp. and Old Kent Financial
Corp. The analysis compared publicly available financial  information for Summit
and the median data for each of the Peer Group and the Commercial  Highly Valued
Group as of and for each of the years ended  December 31, 1993 through  December
31, 1997 and as of and for the twelve months ended March 31, 1998.


ANALYSIS OF SELECTED MERGER TRANSACTIONS

     Sandler O'Neill reviewed 28 transactions  announced from January 1, 1998 to
June 16, 1998  involving  publicly  traded  savings  institutions  nationwide as
acquired   institutions  with  transaction   values  greater  than  $15  million
("Nationwide Transactions"),  and 9 transactions announced from July 25, 1997 to
June 16, 1998 involving  public savings  institutions  in the New England Region
(Connecticut,  Maine, Massachusetts, New Hampshire, Rhode Island and Vermont) as
acquired  institutions  with  transaction  values greater than $15 million ("New
England  Transactions").  Sandler  O'Neill  reviewed  the ratios of  transaction
values  to last  four  quarters'  earnings,  transaction  value  to book  value,
transaction  value  to  tangible  book  value,  tangible  book  premium  to core
deposits,  transaction  value to total deposits and  transaction  value to total
assets and computed  high,  low,  mean,  and median  ratios and premiums for the
respective  groups  of  transactions.  These  multiples  were  applied  to NSS's
financial  information  as of and for the twelve  months  ended March 31,  1998.
Based upon the median  multiples for Nationwide  Transactions,  Sandler  O'Neill
derived an imputed  range of values per share of NSS Common of $51.07 to $67.37.
Based upon the median  multiples for New England  Transactions,  Sandler O'Neill
derived an imputed range of values per share of NSS Common of $47.10 to $57.15.


     No company involved in the  transactions  included in the above analysis is
identical to NSS or Summit and no transaction  included in the above analysis is
identical to the Reorganization.  Accordingly, an analysis of the results of the
foregoing   analysis  is  not   mathematical;   rather,   it  involves   complex
considerations and judgments  concerning  differences in financial and operating
characteristics  of the companies and other factors that could affect the public
trading  value of NSS and  Summit  and the  companies  to which  they are  being
compared.


DISCOUNTED DIVIDEND STREAM AND TERMINAL VALUE ANALYSIS

     Sandler  O'Neill also  performed  an analysis  which  estimated  the future
stream of after-tax  dividend  flows of NSS through the year 2002 under  various
circumstances,  assuming NSS performed in accordance with the earnings forecasts
of its management and certain  variations  thereof.  To approximate the terminal
value of NSS Common at December  31,  2002,  Sandler  O'Neill  applied  price to
earnings multiples ranging from 8x to 26x and applied multiples of tangible book
value ranging from 140% to 320%. The dividend income streams and terminal values
were then discounted to present values using  different  discount rates (ranging
from 9% to 14%) chosen to reflect different assumptions regarding required rates
of  return of  holders  or  prospective  buyers of NSS  Common.  This  analysis,
assuming the current dividend payout ratio and management's  earnings forecasts,
indicated an imputed  range of values per share of NSS Common of between  $13.91
and $51.60 when applying the price to earnings  multiples,  and an imputed range
of values per share of NSS Common of between $24.62 and


                                       20


<PAGE>


$67.10 when applying  multiples of tangible book value.  In connection  with its
analysis,  Sandler  O'Neill  used  sensitivity  analyses to consider the effects
changes in the underlying  assumptions (including variations with respect to the
growth rate of assets, net interest spread,  non-interest  income,  non-interest
expenses and dividend  payout ratio) would have on the  resulting  present value
and discussed  these effects with the NSS Board.  Sandler O'Neill noted that the
discounted  dividend  stream  and  terminal  value  analysis  is a  widely  used
valuation methodology,  but the results of such methodology are highly dependent
upon the numerous assumptions that must be made, and the results thereof are not
necessarily indicative of actual values or actual future results.


PRO FORMA MERGER ANALYSIS


     Sandler  O'Neill  analyzed  certain  potential  pro  forma  effects  of the
Reorganization,  based  upon an  Exchange  Ratio of 1.232,  NSS's  and  Summit's
current and projected  income  statements and balance  sheets,  and  assumptions
regarding  the  economic  environment,  accounting  and  tax  treatment  of  the
Reorganization,   charges   associated  with  the   Reorganization,   and  other
adjustments  discussed with senior managements of NSS and Summit.  This analysis
indicated  that  the  Reorganization  would be  slightly  dilutive  to  Summit's
earnings per share and tangible book value per share in 1999. This analysis also
indicated  that,  from an NSS  shareholder's  perspective,  as  compared  to the
projected stand-alone  performance of NSS, the Reorganization would be accretive
to NSS's  earnings per share,  dilutive to tangible  book value per share of NSS
Common and accretive to dividends per share for all periods analyzed. The actual
results achieved by the combined company may vary from projected results and the
variations may be material. 

     In connection  with  rendering its June 17, 1998 opinion,  Sandler  O'Neill
reviewed,  among other  things:  (i) the  Reorganization  Agreement and exhibits
thereto;  (ii) the  Reorganization  Option  Agreement;  (iii)  certain  publicly
available financial statements of NSS and other historical financial information
provided by NSS that Sandler  O'Neill  deemed  relevant;  (iv) certain  publicly
available  financial   statements  of  Summit  and  other  historical  financial
information provided by Summit that Sandler O'Neill deemed relevant; (v) certain
financial analyses and forecasts of NSS prepared by and reviewed with management
of NSS and the  views of  senior  management  of NSS  regarding  NSS's  past and
current business  operations,  results thereof,  financial  condition and future
prospects;  (vi) certain financial  analyses and forecasts of Summit prepared by
and reviewed  with  management  of Summit and the views of senior  management of
Summit regarding Summit's past and current business operations, results thereof,
financial  condition  and future  prospects;  (vii) the pro forma  impact of the
Reorganization;  (viii)  the  publicly  reported  historical  price and  trading
activity for NSS Common and Summit  Common,  including a  comparison  of certain
financial and stock market  information for NSS and Summit with similar publicly
available  information  for certain other  companies the securities of which are
publicly traded; (ix) the financial terms of recent business combinations in the
savings institution industry, to the extent publicly available;  (x) the current
market environment generally and the banking environment in particular; and (xi)
such other  information,  financial  studies,  analyses and  investigations  and
financial, economic and market criteria as Sandler O'Neill considered relevant.

     In connection with rendering the Sandler O'Neill Fairness Opinion,  Sandler
O'Neill  confirmed the  appropriateness  of its reliance on the analyses used to
render its June 17, 1998 opinion by performing  procedures to update  certain of
such  analyses and by reviewing  the  assumptions  upon which such analyses were
based and the factors considered in connection therewith.

     In performing its reviews and analyses,  Sandler O'Neill assumed and relied
upon, without independent verification, the accuracy and completeness of all the
financial  information,   analyses  and  other  information  that  was  publicly
available  or otherwise  furnished  to,  reviewed by or  discussed  with it, and
Sandler  O'Neill  does not  assume any  responsibility  or  liability  therefor.
Sandler  O'Neill did not make an  independent  evaluation  or  appraisal  of the
specific assets, the collateral  securing assets or the liabilities  (contingent
or otherwise) of NSS or Summit or any of their respective  subsidiaries,  or the
collectibility  of  any  such  assets,  nor  was  it  furnished  with  any  such
evaluations or appraisals. Sandler O'Neill is not an expert in the evaluation of
allowances for loan losses and it has not made an independent  evaluation of the
adequacy of the allowance for loan losses of NSS or Summit,  nor has it reviewed
any individual credit files relating to NSS or Summit. With NSS's consent,


                                       21


<PAGE>


Sandler  O'Neill has assumed that the respective  aggregate  allowances for loan
losses  for both NSS and Summit are  adequate  to cover such  losses and will be
adequate on a pro forma basis for the  combined  entity.  In  addition,  Sandler
O'Neill  has  not  conducted  any  physical  inspection  of  the  properties  or
facilities  of NSS or Summit.  With  respect to all  financial  information  and
projections  reviewed with each company's  management,  Sandler  O'Neill assumed
that they had been  reasonably  prepared on bases  reflecting the best currently
available  estimates  and  judgments  of  the  respective   managements  of  the
respective  future  financial  performances  of NSS and  Summit  and  that  such
performances  will be achieved.  Sandler O'Neill expressed no opinion as to such
financial projections or the assumptions on which they were based.

     Sandler O'Neill's  opinion was necessarily based upon market,  economic and
other  conditions  as they existed on, and could be evaluated as of, the date of
such opinion. Sandler O'Neill assumed, in all respects material to its analysis,
that all of the representations  and warranties  contained in the Reorganization
Agreement and all related  agreements  are true and correct,  that each party to
such  agreements  will perform all of the covenants  required to be performed by
such party  under  such  agreements  and that the  conditions  precedent  in the
Reorganization  Agreement are not waived.  Sandler  O'Neill also  assumed,  with
NSS's  consent,  that there has been no  material  change in NSS's and  Summit's
assets, financial condition, results of operations, business, or prospects since
the date of the last publicly filed financial statements available to them, that
NSS and Summit will  remain as going  concerns  for all periods  relevant to its
analyses,  and that the  Reorganization  will be accounted for as a purchase and
will qualify as a tax-free reorganization for federal income tax purposes.

     Under  the  Sandler  O'Neill  Agreement,  NSS will pay  Sandler  O'Neill  a
transaction fee in connection with the Reorganization,  a substantial portion of
which is contingent upon the consummation of the Reorganization. Under the terms
of the Sandler O'Neill Agreement, NSS will pay Sandler O'Neill a transaction fee
equal to 1.0% of the aggregate  purchase  price paid in the  transaction,  which
price will be  determined  as of the day before the Closing  Date.  Based on the
closing price of Summit Common on _________  (the day preceding the date of this
Proxy Statement-Prospectus),  assuming for purposes of such calculation that the
Reorganization     was     consummated     as    of    the    date    of    this
Proxy-Statement-Prospectus,  NSS would pay Sandler  O'Neill a transaction fee of
approximately  $______ million, of which approximately $______ has been paid and
the balance will be paid when the Reorganization is consummated. Sandler O'Neill
has also received a fee of $75,000 for rendering its fairness  opinion.  NSS has
also  agreed to  reimburse  Sandler  O'Neill  for its  reasonable  out-of-pocket
expenses  incurred in connection  with its engagement  and to indemnify  Sandler
O'Neill and its affiliates and their respective partners,  directors,  officers,
employees,   agents,  and  controlling  persons  against  certain  expenses  and
liabilities, including liabilities under securities laws.

     Sandler O'Neill has in the past provided  certain other financial  advisory
services to NSS and has received compensation for such services. In the ordinary
course of its business,  Sandler  O'Neill may actively  trade the debt or equity
securities of NSS and Summit and their respective affiliates for its own account
and for the accounts of customers and, accordingly,  may at any time hold a long
or short position in such securities.


REORGANIZATION OPTION AGREEMENT

     As an inducement  and condition to Summit's  willingness  to enter into the
Reorganization Agreement, NSS (as issuer) entered into the Reorganization Option
Agreement  with  Summit (as  grantee).  Pursuant  to the  Reorganization  Option
Agreement,  NSS granted the NSS Option to Summit. The NSS Option is an option to
purchase  (a)  prior to the time and date the  shareholders  have  approved  the
Reorganization  Option  Agreement  in  accordance  with the first  paragraph  of
Article  Thirteen  of the  Certificate  of  Incorporation  of NSS, up to 248,308
shares of NSS  Common  at a price of  $45.00  per share or (b) after the date of
such  shareholder  approval,  up to  494,629  shares of NSS Common at a price of
$45.00 per share, exercisable as described below. In addition, NSS agreed to pay
Summit a "break  up" fee of $3.5  million  in the event the NSS  Option  becomes
exercisable  pursuant to the conditions set forth in (a) above.  The purchase of
any shares of NSS  Common  pursuant  to the NSS Option is subject to  compliance
with applicable law.

     Unless Summit is in breach of any material covenant or obligation contained
in the  Reorganization  Agreement and, if the  Reorganization  Agreement has not
terminated  prior  thereto,  such  breach  would  entitle NSS to  terminate  the
Reorganization  Agreement,  Summit may exercise  the NSS Option,  in whole or in
part, at any time


                                       22


<PAGE>


and from time to time  following the  occurrence of a Purchase Event (as defined
below);  provided that the NSS Option will  terminate upon the earliest to occur
of certain events, including:

     (1) the time immediately prior to the Effective Time;

   (2) termination of the Reorganization Agreement prior to the occurrence of an
       Extension  Event (as defined  below) (other than a termination  by Summit
       resulting from (i) a breach thereof by NSS which has not been cured or is
       not capable of being cured within the time allotted (ii)  nonsatisfaction
       of a condition to Summit's  obligation  to close the  Reorganization,  or
       (iii) the failure of the NSS shareholders to approve the Reorganization);
       or

   (3) 15 months after the termination of the Reorganization Agreement following
       the  occurrence  of  an  Extension   Event  (as  defined  below)  or  the
       termination of the  Reorganization  Agreement by Summit upon (i) a breach
       by NSS which has not been cured or is not capable of being  cured  within
       the time  allotted,  (ii)  nonsatisfaction  of a  condition  to  Summit's
       obligation  to close  the  Reorganization,  or (iii) the  failure  of NSS
       shareholders to approve the Reorganization.


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

   (1) NSS,  the NSS Board or any of its  subsidiaries  taking  certain  actions
       (each an "Acquisition  Transaction"),  including recommending or entering
       into  an  agreement  with  any  third  party  to  effect  (a)  a  merger,
       consolidation or similar transaction  involving NSS or any of its banking
       subsidiaries, (b) the purchase, lease, or other acquisition of 10 percent
       or more of the aggregate value of the assets or deposits of NSS or any of
       its  banking  subsidiaries,  (c) the  purchase  or other  acquisition  of
       securities  representing 10 percent or more of the voting power of NSS or
       any  of  its  banking  subsidiaries  or  (d)  any  substantially  similar
       transaction,   in  each  case  except  as  otherwise   permitted  by  the
       Reorganization Option Agreement;


   (2) any third party  acquiring  beneficial  ownership or the right to acquire
       beneficial  ownership of 10 percent or more of the aggregate voting power
       of NSS or any of its banking subsidiaries;

   (3) any third party making a bona fide  proposal to NSS 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 10
       percent  or  more  of the  aggregate  voting  power  of NSS or any of its
       banking subsidiaries);

   (4) after a proposal by a third party to NSS or its shareholders to engage in
       an   Acquisition   Transaction,   NSS   breaches   (without   cure)   any
       representation  or covenant in the  Reorganization  Agreement which would
       entitle Summit to terminate the Reorganization Agreement;

   (5) any third  party  filing an  application  with any  federal or state bank
       regulatory   authority   for   approval  to  engage  in  an   Acquisition
       Transaction; or


     (6) any Purchase Event (as defined below).

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

   (1) any  person  other  than  Summit  or a  subsidiary  of  Summit  acquiring
       beneficial  ownership of 25 percent or more of the aggregate voting power
       of NSS or any of its banking subsidiaries,  except as otherwise permitted
       by the Reorganization Option Agreement; or


   (2) failure  of  the  shareholders  of  NSS  to  approve  the  Reorganization
       Agreement,  failure of the NSS Board to call a meeting for  consideration
       of the  Reorganization  or cancellation of such a meeting,  or if the NSS
       Board  shall  have  withdrawn  or  modified  in a manner  adverse  to the
       consummation of the Reorganization its recommendation with respect to the
       Reorganization Agreement, in each case after an Extension Event; or

   (3) the occurrence of an Extension Event described in subparagraph (1) of the
       definition  of  "Extension  Event"  above,  except  that  the  percentage
       referred to in clauses (b) and (c) thereof shall be 25 percent.


                                       23


<PAGE>


     Upon the  occurrence  of  certain  events  set forth in the  Reorganization
Option  Agreement,  at the election of Summit,  the NSS Option (or shares issued
pursuant to the exercise thereof) must be repurchased by NSS (the  "Repurchase")
or converted  into, or exchanged  for, an option of another  corporation  or NSS
(the "Substitute  Option").  In addition,  the  Reorganization  Option Agreement
grants  certain  registration  rights  ("Registration  Rights")  to Summit  with
respect  to the  shares  represented  by the  NSS  Option.  The  terms  of  such
Repurchase,  Substitute  Option  and  Registration  Rights  are set forth in the
Reorganization Option Agreement.

     The  Reorganization  Option  Agreement  and the NSS Option are  intended to
increase the likelihood that the Reorganization will be consummated according to
the terms set  forth in the  Reorganization  Agreement  and may be  expected  to
discourage offers by third parties to acquire NSS prior to the Reorganization.

     To the  knowledge  of Summit and NSS, no event  giving rise to the right to
exercise   the  NSS  Option  has   occurred   as  of  the  date  of  this  Proxy
Statement-Prospectus.

     A copy of the Reorganization Option Agreement is set forth in Appendix C to
this Proxy Statement-Prospectus,  and reference is made thereto for the complete
terms of the  Reorganization  Option Agreement and the NSS Option. The foregoing
discussion  is qualified  in its  entirety by  reference  to the  Reorganization
Option Agreement.


REGULATORY APPROVALS

     The  Reorganization  is subject to approval by the  Federal  Reserve  Board
under the Bank Holding Company Act of 1956, as amended (the "BHC Act").  The BHC
Act provides that the Federal  Reserve Board may not approve any transaction (1)
that  would  result  in a  monopoly,  or that  would  be in  furtherance  of any
combination or conspiracy to monopolize or to attempt to monopolize the business
of banking in any part of the United  States,  or (2) the effect of which in any
section of the country may be substantially to lessen competition, or to tend to
create a monopoly,  or that in any other  manner would be in restraint of trade,
unless the Federal Reserve Board finds that the  anticompetitive  effects of the
proposed  transaction  are  clearly  outweighed  in the public  interest  by the
probable  effect of the  transaction in meeting the convenience and needs of the
communities  to be  served.  In  conducting  its review of any  application  for
approval,  the Federal  Reserve  Board is required to consider the financial and
managerial  resources  and future  prospects of the company or companies and the
banks concerned,  and the convenience and needs of the communities to be served.
Under the BHC Act, as interpreted  by the Federal  Reserve Board and the courts,
the Federal  Reserve Board may deny any  application  if it determines  that the
financial or  managerial  resources of the  acquiring  bank holding  company are
inadequate.  The  acquisition  by Summit of 5% or more of NSS's  voting stock is
subject  to the same  requirement  for  approval.  The BHC Act  provides  that a
transaction  approved by the Federal Reserve Board may not be consummated for 30
days after such approval 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 such period, the Justice Department may commence legal
action  challenging the transaction  under the antitrust laws. If, however,  the
Justice  Department does not commence legal action during the specified  waiting
period,  it may not challenge  the  transaction  thereafter  except in an action
commenced under Section 2 of the Sherman Antitrust Act.  Satisfactory  financial
condition,  particularly  with  regard to  capital  adequacy,  and  satisfactory
Community  Reinvestment  Act ratings  generally are  prerequisites  to obtaining
Federal Reserve Board approval to make acquisitions.  All of Summit's subsidiary
banks  are  currently  rated   "outstanding"   or  better  under  the  Community
Reinvestment Act.


     An application with respect to the  Reorganization was filed by Summit with
the  Federal  Reserve  Bank of New York on July  24,  1998.  Regulations  of the
Federal  Reserve Board under the BHC Act require  notice of an  application  for
approval  of the  Reorganization  to be  published  in a  newspaper  of  general
circulation  and in the  Federal  Register  and that the public have at least 30
days to comment on the application. In the event one or more comments protesting
approval of the application are received by the Federal Reserve Board within the
time period provided for in the respective notices,  the Federal Reserve Board's
regulations  permit  the  Federal  Reserve  Bank  having  jurisdiction  over the
applicant,  acting on delegated  authority from the Federal  Reserve  Board,  to
arrange a private  meeting  between  the  applicant  and the  protesters  if the
Federal Reserve Bank decides such a meeting would be  appropriate.  In addition,
if an  applicant  or a protestor  requests a hearing or if the  Federal  Reserve
Board  determines  such to be  appropriate,  the Federal Reserve Board may order
that a formal hearing 


                                       24


<PAGE>


on the  application  be held  or that a  proceeding  permitting  all  interested
parties to present  their views orally  before the Federal  Reserve Board or its
designated  representative  be conducted.  Due to the possibility that a private
meeting,  public hearing or proceeding  providing for oral  presentation will be
scheduled by the Federal Reserve Board following  receipt of a protest,  and due
additionally  to  the  procedures   relating  thereto,   Federal  Reserve  Board
processing of  reorganization  applications  receiving one or more protests will
generally take longer than the  processing of  reorganization  applications  not
receiving such protests. The comment period relating to Summit's application for
approval of the Reorganization expires on or about August 28, 1998.

     The  acquisition  of NSS and NSS  Bank by  Summit  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 NSS Bank after
the Reorganization  will be consistent with safe and sound banking practices and
will benefit the state; (ii) the services or proposed services of NSS Bank after
the Reorganization  will be consistent with safe and sound banking practices and
will benefit the economy of the state;  (iii) the  acquisition  of NSS by Summit
will not substantially  lessen  competition in the banking industry in the state
and (iv)  Summit  and NSS Bank will have  sufficient  capital to ensure and will
ensure that NSS Bank will comply with applicable  minimum  capital  requirements
and will have sufficient  managerial resources to operate NSS Bank in a safe and
sound  manner.  In addition,  the  Connecticut  Commissioner  of Banking may not
approve the  acquisition  of NSS Bank by Summit  unless he finds that Summit and
NSS 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 NSS Bank by Summit,  NSS 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 NSS and NSS Bank by Summit  was filed with the
Connecticut Commissioner of Banking on July 24, 1998.

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


INTERESTS OF CERTAIN PERSONS IN THE REORGANIZATION

     Directors   and   executive   officers  of  NSS  have   interests   in  the
Reorganization  that are in addition  to their  interests  as NSS  shareholders.
These interests are described in more detail below.


INDEMNIFICATION

     In the  Reorganization  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 NSS or any  subsidiary  of NSS on or
before the Effective  Time with respect to  liabilities  and claims (and related
expenses  including  fees  and  disbursements  of  counsel)  made  against  them
resulting  from their service as such prior to the Effective  Time in accordance
with and subject to the requirements and other provisions of the Summit Restated
Certificate   of   Incorporation   and   By-Laws  in  effect  on  the  date  the
Reorganization  Agreement was executed and  applicable  provisions of law to the
same extent as Summit is obliged thereunder to indemnify and advance expenses to
its own  directors  and  officers  with respect to  liabilities  and claims made
against them resulting from their service to Summit.  During such time as NSS or
its subsidiaries  remains a separate entity organized under Connecticut law, the
directors  and  officers  thereof  will  be  entitled  to  indemnification   and
advancement of expenses as provided by NSS's or such subsidiary's Certificate of
Incorporation and by-laws and Connecticut law.

     In the Reorganization Agreement,  Summit also agreed that, subject to NSS's
covenant to take all requisite action to preserve its rights under its directors
and officers  liability  insurance  policies  with respect to matters  occurring
prior to the Effective Time (other than matters  arising in connection  with the
Reorganization Agreement and the transaction contemplated thereby), for a period
of six (6) years after the Effective Time, Summit


                                       25


<PAGE>


would use its best  efforts to provide to the persons who served as directors or
officers  of NSS or any  subsidiary  of NSS  on or  before  the  Effective  Time
insurance  against  liabilities  and claims (and related  expenses) made against
them  resulting  from their service prior to the  Effective  Time  comparable in
coverage to that provided by Summit to its own  directors and officers,  but, if
not available on  commercially  reasonable  terms,  then coverage  substantially
similar in all material  respects to the insurance  coverage provided to them in
such  capacities  on the  date  of  the  Reorganization  Agreement  ("Comparable
Coverage");  provided  that in no event is  Summit  required  to  expend  in the
aggregate  for the six years of  post-Reorganization  coverage more than 200% of
the  amount  expended  by NSS  prior  to  the  execution  of the  Reorganization
Agreement for one year of coverage ("Coverage Amount"). Summit has agreed to use
its best efforts to obtain as much comparable  insurance as is available for the
Coverage Amount if it is unable to maintain or obtain Comparable  Coverage.  NSS
must renew any existing  insurance or purchase any "discovery  period" insurance
provided for under existing insurance at Summit's request.

EMPLOYMENT AND CHANGE OF CONTROL AGREEMENTS


     NSS has employment agreements and change of control agreements with Messrs.
Judson, Howell, Dorney and Braverman.  The employment  agreements,  which extend
through March 1, 2001, provide for, among other items, base salaries for Messrs,
Judson,  Howell,  Dorney and  Braverman  of  $185,680,  $126,500,  $99,000,  and
$99,000,  respectively,  and  incentive  compensation  as  determined by the NSS
Board. The employment agreements also provide that if the executive's employment
is  terminated  without  cause,  the executive is entitled to receive a lump-sum
payment  equal to the  greater of (i) the balance of salary that would have been
paid for the  remainder  of term of the  agreement  calculated  at current  base
salary or (ii) an amount  equal to the number of the  executive's  full years of
service  to NSS  Bank  at the  time  of  termination  multiplied  by a  fraction
determined by dividing  current annual base salary by twenty-six.  The change of
control  agreements  provide that in the event a change of control of NSS or NSS
Bank occurs while the executive is a full-time  officer of NSS or NSS Bank,  the
executive  is  entitled to receive a lump-sum  payment  equal to three times the
greater of (1) the executive's compensation for the last calendar year preceding
the change of control or (2) the executive's  average annual compensation during
the three most recent  taxable  years.  Under the change of control  agreements,
compensation  includes  salary and incentive  compensation  (including  deferred
compensation)  as well  as a cash  and  non-cash  long-term  compensation  on an
accelerated  basis  assuming the maximum award is earned.  The change of control
agreements also provide for reimbursement of excise taxes payable as a result of
the change of control payments.  Payments under the change of control agreements
are in lieu of severance payments under the employment agreements and the change
of control agreements expressly supersede provisions contained in the employment
agreements  relating  to  payments  in the  event of a change  of  control.  The
Reorganization will constitute a "change of control" for purposes of such change
of control agreements. The amount of payments to Messrs. Judson, Howell, Dorney,
and Braverman,  pursuant to the foregoing change of control  agreements would be
$1,140,383, $779,348, $609,509, and $609,117, respectively.


EXECUTIVE LONG-TERM INCENTIVE PLAN PAYMENTS

     The NSS 1995  Executive  Incentive  Plan  provides  that in the  event of a
change in control, each grantee of performance stock will receive a cash payment
based upon the maximum award payable under the plan, pro-rated for the length of
time elapsed during the uncompleted performance period. Upon consummation of the
Reorganization,  the  estimated  payments  under  this plan to  Messrs.  Judson,
Howell, Dorney and Braverman, respectively, would be $135,041, $92,001, $72,000,
and $72,000. 


ANNUAL INCENTIVE PLANS PAYMENTS


     Pursuant to the Annual Incentive  Plans,  cash awards are made to executive
officers and directors of NSS upon satisfaction of  pre-established  performance
targets of NSS for the fiscal year. The Annual  Incentive  Plans provide that in
the event of a change of control,  each  participant will receive a cash payment
based upon the maximum award payable under the plan, pro-rated for the length of
time elapsed  during the  uncompleted  fiscal  year.  Upon  consummation  of the
Reorganization,  the  estimated  payments  under these plans to Messrs.  Judson,
Howell, Dorney and Braverman,  respectively, would be $92,840, $63,250, $49,500,
and $49,500 and an  estimated  payment to Mr. St. John of $25,300 and to each of
Messrs. Fitzgerald, Jay, Kelley, Segall and Stack of $16,400.

SEVERANCE POLICY

     Pursuant to NSS's  severance  policy,  all full-time and regular  part-time
employees  with  at  least  one  year  of  service  who do not  have  employment
agreements  with NSS are entitled to severance  payments in the event that their
employment  is  terminated  within  one-year of a change of  control.  Severance
payments for full-time  employees  are  calculated at the rate of two weeks base
pay for each full year of service up to 26 years.



NSS EMPLOYEE STOCK OWNERSHIP PLAN

     Upon  consummation of the  Reorganization,  the NSS ESOP will be terminated
and all  accrued  benefits,  included  benefits  accelerated  as result of early
termination, will be distributed to participants. 


BOARD OF DIRECTORS

     Under the  Reorganization  Agreement,  members of the Board of Directors of
NSS Bank on the date of the  Reorganization  Agreement  are entitled to continue
their  service  as  Directors  of NSS Bank  after the  Effective  Time until the
earlier of (i) one year  following the Effective  Time or (ii) the merger of NSS
Bank into a wholly-owned  bank subsidiary of Summit not organized under the laws
of the State of Connecticut (provided that if such merger occurs within one year
of the  Effective  Time,  such  members may continue to serve for the balance of
such year on an advisory board of directors).


NSS STOCK OPTION PLANS


     As  described  under  "THE  REORGANIZATION-Conversion  of  Stock  Options,"
Original  Options  outstanding  at the  Effective  Time  will  be  automatically
converted  into New Options,  subject to the terms of the  particular NSS Option
Plan and grant  agreement  governing the Original  Option,  including  terms and
provisions governing exercises.  The number of shares covered by the New Options
and the exercise  price thereof will be set by,  respectively,  multiplying  the
number of shares  covered by, and dividing  the exercise  price of, the Original
Option by, the Exchange  Ratio.  Pursuant to the terms of the Employee Plan, all
Original  Options  granted  under  the  Employee  Plan  will be  converted  into
immediately  exercisable  New  Options  whether or not the  Original  Option was
exercisable.  In addition,  in lieu of receiving Summit Common, for a thirty day
period  holders of Original  Options  granted  under the Employee  Plan have the
right to receive cash payments equal to the difference  between the value of the
underlying Summit Common and the adjusted option exercise price.


     The  following  table sets forth certain  information  relating to Original
Options held by Messrs.  Judson,  Howell, Dorney and Braverman and all directors
and executive officers of NSS as a group as follows:  (i) the number of Original
Options held by such persons;  (ii) the number of Original  Options held by such
persons  that are  currently  exercisable;  (iii) the  number  of  unexercisable
Original  Options held by such persons that will be converted  into  exercisable
New Options at the Effective Time; (iv) the weighted  average exercise price for
currently  exercisable Original Options; (v) the weighted average exercise price
for  unexercisable  Original Options that will be converted into exercisable New
Options at the Effective  Time; and (vi) the aggregate net  unrealized  value of
all Original  Options based on the number of shares of Summit Common covered by,
and the exercise  price of, the New Options into which the Original  Options are
convertible  and  using  the last  sale  price of a share of  Summit  Common  on
September  __,  1998 of  $________  as the  market  price  for  purposes  of the
calculation.

(1) Includes  12,000  options to be granted to NSS directors  prior to or at the
    Special  Meeting in lieu of the  option  grant  that  would  otherwise  have
    occured at the 1998 annual meeting.



THE REORGANIZATION AGREEMENT


AMENDMENT

     NSS and Summit may jointly amend the Reorganization  Agreement at any time;
provided,  however, that, after the Special Meeting, no amendment may reduce the
amount  of,  or  change  the  form  of  consideration  to  be  received  by  NSS
shareholders   unless  such   modification   is  submitted  to  a  vote  of  NSS
shareholders.



NSS COVENANTS

     Pursuant to the Reorganization  Agreement, NSS has covenanted,  among other
things, that, until termination of the Reorganization Agreement, NSS will advise
Summit of any material  adverse  change in NSS's  business and of certain  other
circumstances,  and the business of NSS and its subsidiaries  will be carried on
substantially in the same manner as prior to the execution of the Reorganization
Agreement.  Furthermore,  until  termination  of the  Reorganization  Agreement,
without  the prior  written  consent of Summit,  NSS will not declare or pay any
dividend  other than a  quarterly  cash  dividend at a rate up to $.13 per share
(provided  that  if  Summit  increases  its  dividend  after  the  date  of  the
Reorganization  Agreement,  NSS may  increase the $.13 per share by a percentage
equal to the percentage  increase in the Summit  dividend) and will refrain from
taking certain other actions,  including  certain actions relating to changes in
its capital stock, the incurrence of extraordinary  liabilities and the issuance
of capital stock.

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

     NSS also has agreed that, until termination of the Reorganization Agreement
or the Effective Time,  neither NSS nor any of its  subsidiaries  nor any of the
officers  or  directors  of NSS or its  subsidiaries  shall,  and that NSS 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 NSS or any of its subsidiaries)
not to, initiate,  solicit or encourage,  directly or indirectly, any inquiries,
proposals  or  offers  with  respect  to,  or  engage  in  any  negotiations  or
discussions with any person or provide any nonpublic information or authorize or
enter into any  agreement or agreement in principle  concerning,  or  recommend,
endorse or otherwise facilitate any effort or attempt to induce or implement any
Acquisition  Proposal (as defined below).  "Acquisition  Proposal" is defined as
any offer, including an exchange offer or tender offer, or proposal concerning a
merger,  consolidation,  business combination or takeover transaction  involving
NSS or any of its  subsidiaries,  or the  acquisition  of any assets (other than
those permitted under the Reorganization  Agreement) or any securities of NSS or
any of its  subsidiaries.  Further,  NSS is to immediately cease any activities,
discussions, or negotiations with respect to the foregoing. In addition, NSS has
agreed to notify Summit, by telephone call to 


                                       28


<PAGE>


its chief  executive  officer or general  counsel,  promptly upon receipt of any
inquiry 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  NSS  or  any  of  its
subsidiaries  or assets by another  party and to deliver as soon as  possible by
facsimile  transmission  to such Summit officer a copy of any document  relating
thereto promptly after any such document is received by NSS.



SUMMIT COVENANTS


     Pursuant to the  Reorganization  Agreement,  Summit has  covenanted,  among
other things,  that, until termination of the Reorganization  Agreement,  Summit
will advise NSS of any material adverse change in Summit's  business and certain
other circumstances.


CONDITIONS TO THE REORGANIZATION; TERMINATION


     The  obligations  of both  parties to  consummate  the  Reorganization  are
subject to the satisfaction of certain conditions including: (1) approval of the
Reorganization Agreement by the requisite vote of the holders of NSS Common; (2)
receipt  of  all  required  regulatory  approvals  by  Summit  and  NSS  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  Reorganization  and the expiration of any waiting  periods
required by such  approvals;  (3) continued  effectiveness  of the  registration
statement;  (4) the receipt by Summit and NSS of an opinion from Thomson  Coburn
as to certain  federal income tax  consequences  of the  Reorganization;  (5) an
indication  by the NYSE that the  shares  of  Summit  Common to be issued in the
Reorganization  are to be listed  on the NYSE,  subject  to  official  notice of
issuance; (6) the absence of material litigation;  (7) the absence of regulatory
agreements relating to the parties;  (8) the delivery of officers'  certificates
by  NSS  and  Summit;  and  (9)  other  customary  conditions  described  in the
Reorganization  Agreement. Any of such conditions may be waived by the party for
whose benefit the condition was included.  However,  the Reorganization will not
be consummated  without the receipt of the requisite  shareholder and regulatory
approvals. 

     Either  party  may  terminate  the  Reorganization  Agreement  if  (1)  NSS
Shareholders,  in a vote on the  Reorganization  Agreement at a meeting held for
such  purpose,  fail to approve the  Reorganization  Agreement by the  requisite
vote,  (2) the other party  materially  breaches a warranty,  representation  or
covenant  and such breach is not cured or capable of being cured  within 30 days
of the giving of written notice thereof  (provided that the terminating party is
not in  material  breach  of any  representation,  warranty,  covenant  or other
agreement),  (3) on the date for  Closing  designated  by Summit in the  Closing
Notice, all the conditions  precedent to such parties'  obligations to close are
not met,  or (4) the  Closing  is not  consummated  on or before  March 1, 1999,
provided, however, that a party does not have the termination right described by
this  clause (4) if the  failure to close by March 1, 1999 is due to its failure
to perform or observe an agreement which the  Reorganization  Agreement requires
it to perform or observe by the  Closing  Date.  In  addition,  the  parties may
terminate  the  Reorganization  Agreement  at any time by mutual  agreement.  In
addition,  the NSS Board  may  terminate  the  Reorganization  Agreement  if the
average  closing  prices  of a share of  Summit  Common  on the  NYSE  Composite
Transactions List for the 10 consecutive full trading days ending on the date of
the  Required  Approval  given by the FRB is less  than  $39.11  and the  number
obtained by dividing  the Summit Price by $47.125 is more than .17 less than the
number  obtained by dividing the average  closing  price per share of the common
stocks of 18 bank holding  companies  for the 10  consecutive  full trading days
ending on the FRB Approval  Date by the average  closing  price per share of the
common  stocks  of the  Index  Group on June 16,  1998.  The  Summit  Board  may
terminate  the  Reorganization  Agreement  if the NSS Board  fails to  recommend
approval of the Reorganization  Agreement or withdraws such recommendation or if
the cost of certain  environmental  matters exceeds  thresholds set forth in the
Reorganization Agreement.


EXPENSES

     Should either party  terminate  the  Reorganization  Agreement  because the
other party has materially  breached a warranty,  representation  or covenant or
because  the other  party has not met its  conditions  of  closing  or if Summit
terminates  because  the NSS Board  fails to  recommend  the  Reorganization  or
because of the environmental contingency referred to above, then the terminating
party shall be reimbursed by the defaulting party for


                                       29


<PAGE>


the terminating party's out of pocket expenses reasonably incurred in connection
with the  Reorganization  Agreement,  including counsel fees,  printing fees and
filing fees, but excluding any brokers',  finders' or investment  bankers' fees.
In the event that the  Reorganization  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 Reorganization  Agreement,
except that each party is responsible  for one-half of the expenses  incurred in
connection  with  the  printing  of  this  Proxy  Statement-Prospectus  and  the
Registration  Statement  and the filing  fees with the  Commission,  the Federal
Reserve Board,  the  Connecticut  Department of Banking and the NYSE. Each party
has  agreed to  indemnify  the other for claims for  brokerage  commissions  and
finders fees.


CHARTER AND BY-LAWS OF SURVIVING CORPORATION

     Pursuant to the  Reorganization  Agreement,  the  Restated  Certificate  of
Incorporation and By-Laws of Summit, as in effect at the Effective Time, will be
the  Restated   Certificate  of  Incorporation  and  By-Laws  of  the  surviving
corporation (the "Surviving Corporation"), unless and until amended.


BOARD OF DIRECTORS AND OFFICERS OF SURVIVING CORPORATION

     The  Reorganization  Agreement  provides that the directors and officers of
Summit immediately prior to the Effective Time will continue to be the directors
and officers, respectively, of the Surviving Corporation.


DISSENTERS' RIGHTS

     Any NSS  shareholder  who objects to the  Reorganization  Agreement has the
right to be paid  the  fair  value of all  shares  of NSS  Common  owned by such
shareholder in accordance  with the  provisions of Sections  33-855 to 33-872 of
the  CBCA,  a  copy  of  which  is  set  forth  in  Appendix  D  to  this  Proxy
Statement-Prospectus.  The following  discussion is not a complete  statement of
the law pertaining to such rights, and is qualified in its entirety by reference
to such sections of the CBCA.

     If the  Reorganization  is  consummated,  a shareholder of NSS who does not
vote in favor of the approval and adoption of the Reorganization  Agreement, and
who  follows  the  statutory   provisions  of  the  dissenters'  rights  statute
summarized  herein may require Summit to pay the fair value of his or her shares
of NSS Common, determined as provided in the dissenters' rights statute.


     A shareholder  of NSS who desires to pursue his or her  dissenters'  rights
must  deliver  to NSS,  before  the  taking  of the  vote on the  Reorganization
Agreement, a written notice of intent to demand payment for his or her shares if
the  Reorganization  is  effectuated.  Notice of an intention to demand  payment
should be  addressed to Jeremiah T. Dorney,  Corporate  Secretary,  NSS Bancorp,
Inc., 48 Wall Street, Norwalk,  Connecticut 06852. The shareholder must then not
vote any shares in favor of the  approval  and  adoption  of the  Reorganization
Agreement.  A vote  against the  approval  and  adoption  of the  Reorganization
Agreement,  whether by proxy or in person at the NSS Meeting, is not required to
preserve  a  shareholder's  dissenters'  rights,  nor  will a  negative  vote be
considered  a demand for payment in and of itself  without  compliance  with the
requirements  set forth in  Appendix  D,  including  the  delivery  prior to the
shareholder  vote of the notice of intent to demand  payment.  A NSS shareholder
who  votes in favor  of the  Reorganization  Agreement  will be  precluded  from
exercising dissenters' rights.

     If the  Reorganization  Agreement  is approved  and all  conditions  to the
Reorganization are satisfied or waived, Summit will send a dissenters' notice to
shareholders  who have given written  notice of intent to demand  payment within
ten days after the consummation of the  Reorganization.  The dissenters'  notice
will state where the shareholder's demand for payment must be sent and where and
when certificates for certificated  shares must be deposited;  inform holders of
uncertified  shares to what extent  transfer  of the shares  will be  restricted
after the payment demand is received;  supply a form for demanding  payment that
includes the date of the first  announcement to news media or to shareholders of
the terms of the Reorganization Agreement (June 18, 1998); 


                                       30


<PAGE>


and require that each shareholder  asserting  dissenters' rights certify whether
or not such shareholder  acquired beneficial ownership of the shares before that
date.  Finally,  Summit will set a date by which Summit must receive the payment
demand,  which  date will not be fewer  than 30 nor more than 60 days  after the
date of the  written  dissenters'  notice.  Each such  dissenters'  notice  will
include a copy of CBCA Sections 33-855 to 33-872. 

     Within  the  time  period  set  forth in  Summit's  dissenters'  notice,  a
dissenting  shareholder  must  demand  payment for his or her shares and certify
whether he or she  beneficially  owned such  shares  prior to June 18,  1998.  A
shareholder  who demands  payment must deposit the  certificate or  certificates
representing  such  shares  with  Summit  in  accordance  with the  terms of the
dissenters'  notice.  Failure to demand  payment or deposit  share  certificates
terminates a shareholder's dissenters' rights.

     A demand for payment may be executed by or for the record  shareholder,  as
the shareholder's name appears on the share  certificate.  A beneficial owner of
shares of NSS Common who is not the record owner may demand payment with respect
to all  (but  not  less  than  all)  shares  held  on his or her  behalf  if the
beneficial  owner  submits  to  NSS at or  before  the  assertion  of his or her
dissenters' rights written consent of the record holder. A record owner, such as
a broker,  who holds NSS Common for others,  may demand  payment with respect to
less than all of the shares of NSS Common held of record by such person. In that
event,  the record  owner must demand  payment  with respect to all shares owned
beneficially by the same person,  and must provide NSS with the name and address
of each person on whose behalf such demand is being made.

     With respect to shares acquired by a dissenting shareholder before June 18,
1998, Summit will pay, as soon as the  Reorganization is consummated or promptly
after receipt of a  post-Reorganization  demand, to each shareholder who makes a
proper demand for payment,  the amount Summit estimates to be fair value of such
shareholder's  shares  (plus  accrued  interest).  The payment by Summit to such
shareholder  will be  accompanied  by: NSS's  balance  sheet for the fiscal year
ending not more than 16 months before the date of payment;  an income  statement
for that year; a statement of changes in shareholders' equity for that year; the
latest available interim financial  statements,  if any, a statement of Summit's
estimate of the fair value of the shares; an explanation of how the interest was
calculated;  a  statement  of the  dissenting  shareholder's  rights  to  demand
payment; and a copy of the dissenters' rights sections of the CBCA.

     Summit may elect to withhold  payment to a  shareholder  who makes a demand
for payment if the shareholder was not the beneficial owner of NSS Common before
June 18, 1998. If Summit elects to withhold payment to such shareholder,  Summit
will send to the  dissenting  shareholder  its offer of  payment  (plus  accrued
interest)  accompanied by a statement of Summit's  estimate of the fair value of
the shares, an explanation of how the interest was calculated and a statement of
the  shareholder's  right to demand  payment if  dissatisfied.  A  shareholder's
acceptance of such offer is in full satisfaction of the shareholder's demand.

     If  dissatisfied   with  Summit's   payment  or  offer,  a  dissenting  NSS
shareholder  must,  within 30 days after Summit makes or offers payment,  notify
Summit in writing of such  shareholder's  own  estimate of the fair value of his
shares  and the  amounts  of  interest  due,  and  demand  payment of his or her
estimate,  less any payment by Summit,  or may reject  Summit's offer and demand
payment for the fair value of his or her shares and interest owing.  Such action
may be  taken  only if (a) the  shareholder  believes  that the  amount  paid or
offered  is less  than the fair  value of the  shareholder's  shares or that the
interest  due is  incorrectly  calculated;  or (b) Summit  fails to make payment
within 60 days  after the date set for the  shareholder's  demand  for  payment.
Failure  to make such a demand  within  the 30 day  period  will be treated as a
waiver of the  shareholder's  right to demand payment in an amount exceeding the
amount previously paid or offered by NSS.

     If a NSS shareholder's  demand for payment remains  unsettled,  Summit will
commence a  proceeding  within 60 days after  receipt of  shareholder's  payment
demand  in   Connecticut   Superior   Court  for  the   judicial   district   of
Stamford/Norwalk  to determine  fair value of the shares (plus accrued  interest
thereon) making each  dissenting  shareholder  whose demand remains  unsettled a
party to the  proceeding.  If Summit fails to timely  commence such  proceeding,
Summit shall pay each dissenting  shareholder whose demand remains unsettled the
amount demanded. The court may, if it so elects, appoint appraisers to recommend
the  fair  value  of NSS  Common.  Each  NSS  shareholder  made a  party  to the
proceeding is entitled to the excess of fair value of such shareholder's  shares
(as determined by the court),  plus interest over the amount paid by Summit,  or
to the fair value (plus 


                                       31


<PAGE>


accrued  interest)  of the after  acquired  shares for which  Summit  elected to
withhold payment. The costs and expenses,  including the reasonable compensation
and expenses of court appointed appraisers, will be assessed against Summit. All
or any part of such costs and expenses may be apportioned  and assessed  against
any or all  shareholders  who are parties to the  proceedings to whom Summit has
made  an  offer  for  payment  if the  court  finds  that  the  action  of  such
shareholders was arbitrary or vexatious or not in good faith.

     Any  holder of NSS  Common  who  intends  to  object to the  Reorganization
Agreement should  carefully review the text of the applicable  provisions of the
CBCA set forth in Appendix D to this Proxy  Statement-Prospectus and should also
consult with such  holder's  attorney.  THE FAILURE OF A HOLDER OF NSS COMMON TO
FOLLOW PRECISELY THE PROCEDURES SUMMARIZED ABOVE AND SET FORTH IN APPENDIX D MAY
RESULT IN LOSS OF  DISSENTERS'  RIGHTS.  No further  notice of the events giving
rise to dissenters'  rights or any steps associated  therewith will be furnished
to holders of NSS Common, except as otherwise required by law.

     In general, any objecting shareholder who perfects the right to be paid the
fair value of such  holder's NSS Common in cash will  recognize  taxable gain or
loss for  federal  income tax  purposes  upon  receipt of such cash in an amount
equal to the  difference  between the amount of cash received and their adjusted
tax basis in the NSS Common.


NEW YORK STOCK EXCHANGE LISTING

     Summit has agreed in the  Reorganization  Agreement to use its best efforts
to cause the shares of Summit  Common to be issued in the  Reorganization  to be
listed on the NYSE. The NYSE's  indication that such shares of Summit Common are
to be listed on the NYSE (subject to official notice of issuance) is a condition
to the consummation of the Reorganization.


ACCOUNTING TREATMENT


     It is  anticipated  that  the  Reorganization,  when  consummated,  will be
treated as a purchase.  Under the purchase  method of accounting,  the amount by
which the purchase price paid by Summit exceeds the fair value of the net assets
acquired will be treated as goodwill,  which will be amortized over a period not
to exceed 20 years. 


CERTAIN FEDERAL INCOME TAX CONSEQUENCES OF THE REORGANIZATION

     The  following  discussion  is based upon an opinion  of  Thompson  Coburn,
special  counsel  to Summit  ("Counsel"),  and  except as  otherwise  indicated,
reflects Counsel's  opinion.  The discussion is a summary of the material United
States  federal  income  tax  ("federal   income  tax")   consequences   of  the
Reorganization to certain NSS shareholders and does not purport to be a complete
analysis or listing of all potential tax considerations or consequences relevant
to a decision whether to vote for the approval of the Reorganization  Agreement.
The discussion  does not address all aspects of federal income taxation that may
be  applicable  to NSS  shareholders  in  light  of  their  status  or  personal
investment   circumstances,   nor  does  it  address  the  federal   income  tax
consequences  of the  Reorganization  that are  applicable  to NSS  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 NSS Common  pursuant to the
exercise of employee stock options or otherwise as compensation, and persons who
hold  their  NSS  Common  as  part  of  a  "straddle,"  "hedge"  or  "conversion
transaction."  In addition,  the  discussion  does not address the effect of any
applicable  state,  local or foreign tax laws,  or the effect of any federal tax
laws other than those  pertaining to the federal  income tax. As a result,  each
NSS  shareholder is urged to consult his or her own tax advisor to determine the
specific  tax  consequences  of the  Reorganization  to  such  shareholder.  The
discussion  assumes that shares of NSS Common are held as capital assets (within
the meaning of Section 1221 of the Code) at the Effective Time.

     NSS has received an opinion  from Counsel to the effect that,  assuming the
Reorganization  occurs in  accordance  with the  Reorganization  Agreement,  the
Reorganization  will  constitute  a  "reorganization"  for  federal  income  tax
purposes under Section  368(a)(1) of the Code, with the following federal income
tax consequences:


                                       32


<PAGE>


   (1) NSS  shareholders  will  recognize  no gain or  loss as a  result  of the
       exchange of their NSS Common solely for shares of Summit Common  pursuant
       to the  Reorganization,  except with respect to Cash in Lieu Amounts with
       regard to fractional shares, if any, as discussed below.


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


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



   (4) An NSS  shareholder who receives the Cash In Lieu Amount with regard to a
       fractional  share of Summit  Common will be treated as if the  fractional
       share had been received by such  shareholder  in the  Reorganization  and
       then  redeemed  by  Summit  in return  for the Cash In Lieu  Amount.  The
       receipt of such cash will cause the  recipient to recognize  capital gain
       or loss equal to the  difference  between the amount of cash received and
       the portion of such  holder's  adjusted tax basis in the shares of Summit
       Common allocable to the fractional share.


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


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


RESALE OF SUMMIT COMMON


     The shares of Summit  Common into which shares of NSS Common are  converted
on the  Effective  Date will be freely  transferable  under the  Securities  Act
except  for  shares  issued  to  any  shareholder  who  may be  deemed  to be an
"affiliate"  of NSS for purposes of Rule 145 under the  Securities Act as of the
date of Special  Meeting.  Affiliates may not sell their shares of Summit Common
acquired in connection with the  Reorganization  except pursuant to an effective
registration  statement  under the  Securities  Act  covering  such shares or in
compliance  with  Rule  145  under  the  Securities  Act or  another  applicable
exemption from the registration  requirements of the Securities Act. Persons who
may be deemed to be affiliates of NSS generally include  individuals or entities
that control,  are  controlled  by or are under common  control with NSS and may
include certain officers and directors of NSS as well as principal  shareholders
of NSS.


                                       33


<PAGE>


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

DIFFERENCES IN SHAREHOLDERS' RIGHTS

     The  rights  of NSS  shareholders,  which  are  determined  by  Connecticut
corporation law and the certificate of Incorporation  and By-Laws of NSS, differ
from the rights accorded Summit shareholders, which are determined by New Jersey
corporation  law and the Restated  Certificate of  Incorporation  and By-Laws of
Summit.  Some of the  differences in  shareholders'  rights are  attributable to
differences  between  the  corporation  law of  Connecticut,  the state of NSS's
incorporation,  and the  corporation  law of New  Jersey,  the state of Summit's
incorporation.   The  remaining   differences   in   shareholders'   rights  are
attributable to differences between the Certificate of Incorporation and By-Laws
of NSS and Restated Certificate of Incorporation and By-Laws of Summit.  Certain
of the  rights  of NSS  shareholders  described  below  which  are  provided  by
Connecticut  corporation law or contained in the Certificate of Incorporation or
By-Laws  of NSS and which are not  provided  by New  Jersey  corporation  law or
contained in the Restated  Certificate of Incorporation or By-Laws of Summit are
deemed  to have  an  anti-takeover  effect  and  will  not be  available  to NSS
shareholders as Summit shareholders; however, certain rights provided for by New
Jersey  corporation law or the Restated  Certificate of Incorporation or By-Laws
of Summit are also deemed to have an anti-takeover  effect and will be available
to NSS shareholders only after becoming Summit shareholders.  The following is a
summary discussion of the most significant  differences in shareholders' rights.
This summary is qualified in its entirety by reference to the  corporation  laws
of  Connecticut  and New Jersey and the  governing  documents  of NSS and Summit
referred to above.


COMPARISON OF CERTIFICATES OF INCORPORATION AND BY-LAWS


CLASSIFIED BOARD AND RELATED PROVISIONS



     NSS. The  Certificate  of  Incorporation  of NSS divides the NSS Board into
three  classes,  as  nearly  equal in  number as  possible,  with each  class of
directors  serving a  staggered  term of three years and  provides  that the NSS
Board  shall  consist  of not less than  seven nor more than  eleven  directors.
Directors are elected by a plurality of votes cast by  shareholders  entitled to
vote.  Presently,  there are three  directors in Class One,  three  directors in
Class Two and two directors in Class Three. 

     SUMMIT.  The Restated  Certificate of Incorporation of Summit provides that
the  Summit  Board  shall  consist of not less than five and not more than forty
persons  and  divides the Summit  Board into three  classes,  with each class of
directors  serving a staggered term of three years. Each class of directors must
consist,  as  nearly  as  possible,  of one  third of the  number  of  directors
constituting  the entire Summit  Board.  Directors are elected by a plurality of
votes cast by shares  entitled to vote.  Presently  there are seven directors in
Class I, five directors in Class II and six directors in Class III.

     The Restated  Certificate of  Incorporation of Summit further requires that
resolutions  increasing  the number of  directors  be approved by 80% of, as the
case may be,  directors  holding  office or shares  of  capital  stock of Summit
entitled to vote  generally  in the  election of  directors,  voting as a single
class.

     The Restated  Certificate of Incorporation of Summit also provides that the
affirmative  vote of the holders of 80% or more of the combined voting shares of
Summit,  voting as a single  class,  is  required  to amend,  repeal or take any
action  inconsistent  with the classified  board of directors or the requirement
for an 80% affirmative  vote to approve any increase in the number of directors.
The effect of these  provisions  is to make it difficult  for persons other than
those negotiating  directly with the Summit Board to acquire seats on the Summit
Board and obtain control of Summit.


MEETINGS AND CONSENTS


     NSS. NSS's  Certificate of  Incorporation  and By-Laws  provide that unless
otherwise  required by law, a special meeting of shareholders may be called only
by the  Chairman  of the Board,  the  President,  or a majority  of the Board of
Directors.  Pursuant to the CBCA,  special meetings must be held upon the demand
of holders


                                       34


<PAGE>


of not less than  thirty-five  percent of shares  entitled  to vote on a matter.
Under the NSS Certificate of Incorporation,  actions required or permitted to be
taken by  shareholders  must be  effected  at a duly  called  annual or  special
meeting and may not be taken by any consent in writing of shareholders.

     SUMMIT.  Under  Summit's  By-Laws,  except as  otherwise  provided  by law,
special meetings may be called only by the Chairman, Vice Chairman, President or
majority of the entire  Board.  The Restated  Certificate  of  Incorporation  of
Summit  requires  that,  subject  to the  rights  of  holders  of any  series of
Preferred  Stock or other class or series of stock  having  preference  over the
Summit  Common  as  to  dividends  or  upon  liquidation,  all  actions  by  the
shareholders  of Summit be taken  exclusively at a duly called annual or special
meeting  of  Summit's  shareholders  or by the  unanimous,  but  not  less  than
unanimous,  written consent of the shareholders.  An additional provision in the
Restated  Certificate of  Incorporation  of Summit provides that the affirmative
vote of the  holders  of 80% or more of the  combined  voting  shares of Summit,
voting as a single class, is required to amend, alter, repeal or take any action
inconsistent  with  this  requirement.  Under  the  Summit  By-Laws,  except  as
otherwise required by law or Summit's Restated Certificate of Incorporation, all
actions by shareholders  must be taken at a meeting unless the Board  determines
that such action shall be taken by written consent.


FAIR PRICE, EVALUATION OF BUSINESS COMBINATIONS AND BENEFICIAL OWNERSHIP
   LIMITATIONS


     NSS FAIR PRICE  PROVISION.  The NSS Certificate of  Incorporation  provides
that a  "super-majority"  vote of  shareholders  must approve  certain  business
combinations,  including  mergers,  consolidations,  share  issuances,  sales of
assets,  liquidations,  dissolutions  or  reclassifications,  between NSS and an
"Interested   Shareholder"  (as  such  term  is  defined  below)  or  any  other
corporation (whether or not itself an Interested  Shareholder) which is or after
such merger would be, an affiliate or associate of any  Interested  Shareholder,
unless  the  transaction  is  approved  by the NSS Board or  certain  fair price
procedural requirements are satisfied. An "Interested  Shareholder" is generally
defined  as a  person  or  entity  who  is the  beneficial  owner,  directly  or
indirectly,  of 10% or more of the  voting  power of the  outstanding  shares of
voting stock of NSS. Such  transactions  must first be approved by the NSS Board
and then by the  affirmative  vote of the  holders of at least 80% of the voting
power of the then  outstanding  shares of voting stock, and by two-thirds of the
voting power of the  outstanding  shares of the voting stock exclusive of shares
held by or on behalf of the Interested Shareholder,  unless: (1) the transaction
is approved by the NSS Board before the Interested  Shareholder  first became an
Interested Shareholder;  (2) or in the case of a merger,  consolidation or share
exchange,  and in all  other  business  combinations,  certain  fair  price  and
procedural  provisions are met. In general,  the fair price  provisions  require
that shareholders  whose stock is acquired in a business  combination be paid at
least as much as the highest price the  Interested  Shareholder  paid for shares
within the two prior years or the price that the Interested  Shareholder paid in
the transaction by which the Interested  Shareholder  first became an Interested
Shareholder, whichever is higher. The procedural provisions include prohibitions
against  omissions of dividends on preferred  stock,  reductions in dividends on
NSS Common and acquisitions by the Interested  Shareholder of more stock of NSS.
The provisions of the NSS Certificate of Incorporation are substantially similar
to  applicable   provisions  of  the  CBCA.  Summit's  Restated  Certificate  of
Incorporation  does not contain a similar fair price provision  although the New
Jersey  Shareholder's  Protection  Act  contains  a fair  price  provision.  See
"Comparison of Corporation Laws".


     EVALUATION OF OFFERS. The Certificate of Incorporation of NSS provides that
the NSS Board,  when  evaluating  any tender or exchange  offer for stock of the
corporation,  offer or proposal to merge or  consolidate  the  corporation  with
another  institution,  or an offer or proposal to purchase or otherwise  acquire
all or substantially all of the properties and assets of the corporation, shall,
in connection  with the exercise of its judgment in  determining  what is in the
best interests of the corporation and its  shareholders,  give due consideration
to all  relevant  factors,  including  without  limitation  what  it  reasonably
believes  to be in the best  interests  of the  corporation  including:  (a) the
long-term  as well  as the  short-term  interests  of the  corporation;  (b) the
long-term and short-term  interests of  shareholders,  including the possibility
that those  interests  may be best  served by  continued  independence;  (c) the
interest of the corporation's employees, customers, creditors and suppliers; (d)
community and social  considerations  including  those of any community in which
any office or other facility of the  corporation  is located;  and (e) any other
factor which the director  determines in his or her discretion to be appropriate
in  determining  what he reasonably  believes to be in the best interests of the
corporation.  The foregoing  provisions are substantially  similar to applicable
provisions in the CBCA. Summit's Restated Certificate 


                                       35


<PAGE>


of  Incorporation  does not  contain a similar  provision.  However,  New Jersey
corporation  law  provides  that a  director  of a New  Jersey  corporation,  in
discharging his or her duties to the  corporation and in determining  what he or
she reasonably believes to be in the best interests of the corporation,  may, in
addition to considering the effects of any action on shareholders,  consider any
of the following:  (a) the effects of the action on the corporation's employees,
suppliers,  creditors  and  customers;  (b) the  effects  of the  action  on the
community in which the  corporation  operates;  and (c) the long-term as well as
the short-term interests of the corporation and its shareholders,  including the
possibility   that  these   interests  may  best  be  served  by  the  continued
independence of the corporation.  Determinations resulting in the rejection of a
proposal  or offer to acquire  the  corporation  are  expressly  covered by this
provision of the New Jersey Business Corporation Act.


     NSS BENEFICIAL OWNERSHIP  LIMITATION.  The NSS Certificate of Incorporation
prohibits any person or group from  acquiring 10% or more of the voting stock of
NSS without the approval of the Connecticut  Commissioner of Banking unless such
acquisition has been approved by an affirmative vote of two-thirds of each class
of voting stock and all requisite  federal and state  regulatory  approvals have
been  obtained.  Further,  no person may make an offer to acquire 10% or more of
the voting stock unless the NSS Board has been notified in writing of such offer
and has not disapproved thereof and the requisite regulatory approvals have been
obtained.  Any person  who does not  comply  with the  foregoing  provisions  is
prohibited from voting shares held in excess of 10% and the NSS Board may direct
that such excess shares be sold. Summit's Restated  Certificate of Incorporation
does not contain a similar beneficial ownership limitation provision.


SHAREHOLDER RIGHTS PLANS


     NSS. NSS has a shareholder  rights agreement ("NSS Rights Agreement") which
provides that automatically attached to each share of NSS Common is one right (a
"NSS Right") which,  when  exercisable,  entitles the holder of the NSS Right to
purchase one  one-hundredth  of a share of Series A Preferred at a price of $40,
subject to adjustment.  The NSS Rights become exercisable when a person acquires
an ownership interest in NSS (in general,  10% of the outstanding shares of NSS)
so as to become an  "Acquiring  Person" or commences an offer to acquire  shares
which would make such person an "Acquiring  Person" (such  acquisition  or offer
being  referred  to as the  Distribution  Date).  Shares of  Series A  Preferred
entitle holders thereof to 100 times the dividend, voting and liquidation rights
of NSS  Common,  as well as the right to  receive  100  times the  consideration
received by holders of NSS Common in a merger. In the event NSS is acquired in a
merger after the occurrence of a "Distribution Date", the NSS Rights entitle the
holders  thereof to receive,  upon  exercise of the right,  common  stock of the
acquiring  company with a value of five times the  exercise  price of the right.
Accordingly,  exercise of NSS rights may cause substantial  dilution to a person
that  attempts to acquire NSS without NSS Board  approval  and may have  certain
anti-takeover  effects.  See  "Description  of NSS Capital  Stock -  Shareholder
Rights Agreement".


     SUMMIT.  Summit has in effect a  shareholder  rights plan pursuant to which
holders of shares of Summit Common  possess one preferred  stock  purchase right
for each share of Summit  Common held by them.  Each  preferred  stock  purchase
right  entitles  the holder to buy, as of the close of business on the tenth day
following the occurrence of certain  takeover-related events ("effective time"),
one  one  hundred-fiftieth  of a  share  of a new  series  of  Preferred  Stock,
designated  the Series R Preferred  Stock,  at $60 per one one  hundred-fiftieth
share ("exercise price"),  with full shares having rights per share equal to 150
times the  rights  of Summit  Common  with  respect  to  voting,  dividends  and
distributions  upon  liquidation or merger as well as entitling the holder to an
additional  preferential  dividend.  Upon the occurrence of certain subsequently
occurring events, holders of the preferred stock purchase rights become entitled
to  purchase  either  shares of the  Series R  Preferred  Stock (if not  already
purchased)  or a number of shares of the  "acquiring  person" (as defined in the
rights plan) equal in market value to twice the exercise  price of the preferred
stock  purchase  right.  The Summit Board has the power to redeem the  preferred
stock purchase rights at any time but, after the preferred stock purchase rights
become  exercisable,  it may do so only upon the majority vote of non-management
directors in  connection  with a business  combination  it has  approved.  For a
further  description of Summit's  shareholder  rights plan, see  "DESCRIPTION OF
SUMMIT CAPITAL  STOCK-Shareholder  Rights Plan." The  combination of prohibitive
dilution of the acquiring person's share value and the power of the Summit Board
to redeem the preferred stock purchase


                                       36


<PAGE>


rights is intended to encourage  potential  acquiring  persons to negotiate with
the  Summit  Board  with  respect to the terms of any  acquisition  or  business
combination  and to  the  extent  possible,  discourage  or  defeat  partial  or
two-tiered acquisition proposals.


NOMINATIONS TO THE BOARD, SHAREHOLDER PROPOSALS AND CONDUCT OF MEETING


     NSS.  Pursuant to NSS's By-Laws,  nominations  for election to the Board of
Directors  may be made by the Board of  Directors or by any  shareholder  of any
outstanding  class  of  capital  stock  entitled  to vote  for the  election  of
directors.  NSS  shareholders  may nominate  directors for election by providing
written notice to NSS's Secretary  delivered or mailed not less than twenty (20)
days prior to the meeting.  The presiding officer of the meeting shall disregard
any shareholder nomination to the NSS Board which is not made in accordance with
the Certificate of  Incorporation.  Holders of NSS Common may not cumulate their
votes in elections of directors.


     SUMMIT.  The By-Laws of Summit contain  provisions  that empower the Summit
Board to adopt rules,  regulations and procedures  governing  meetings of Summit
shareholders  and  empower  the  chairman  of a meeting of Summit  shareholders,
subject to the rules and regulations  adopted by the Summit Board, to adopt such
rules,  regulations  and  procedures  and to take such actions that the chairman
deems  necessary,  appropriate  or  convenient  for  the  proper  conduct  of  a
shareholder  meeting.  The  Summit  By-Laws  also  contain  provisions  that (1)
establish  rules governing  nominations  for director and shareholder  proposals
made at meetings of  shareholders  and, in general,  empower the  chairman of an
annual meeting to disallow  nominations and  shareholder  proposals that are not
made at least 80 days in  advance of the  anniversary  of the  preceding  year's
annual  meeting or that otherwise  fail to comply with the  requirements  of the
By-Laws and (2) establish  rules  governing  nominations  for directors  made at
special  meetings of shareholders  and empower the chairman of a special meeting
to disallow nominations that are not made at least 70 days prior to such special
meeting or the 10th day following the day on which public  announcement  of such
special  meeting  is  first  made or that  otherwise  fail to  comply  with  the
requirements  of the By-Laws.  Holders of Summit  Common may not cumulate  their
votes in elections of directors. 


VOTE REQUIRED FOR CHARTER AND BY-LAW AMENDMENTS



     NSS. In general,  any  amendment of the NSS  Certificate  of  Incorporation
requires the affirmative vote of a majority of the outstanding  voting shares of
NSS Common entitled to vote thereon.  The amendment of certain provisions of the
NSS  Certificate of  Incorporation,  including those dealing with capital stock,
the  election  of the NSS Board,  amendment  of  By-Laws,  approval  of Business
Combinations, the calling of special meetings of shareholders,  vacancies on the
NSS Board, removal of directors, notice of shareholder nominations of candidates
for the election of  directors,  the  elimination  of  shareholders'  actions by
consent,  approval of acquisitions of 10% or more of the company's voting stock,
factors to be  considered by the NSS Board in  evaluating  certain  transactions
such  as  tender  or  exchange  offers,  the  addition  of an  article  imposing
cumulative  voting for the  election  of  directors,  and any  amendment  of the
procedure  for  amending  the  foregoing  provisions  must  be  approved  by the
affirmative  vote of the holders of not less than 60% of shares of NSS  entitled
to vote  thereon.  If there is an  Interested  Shareholder,  such 60% vote  must
include the affirmative  vote of not less than two-thirds of the voting power of
the NSS  Common  held by  shareholders  other than the  Interested  Shareholder.
Pursuant to NSS's  Certificate of Incorporation  and By-Laws,  the NSS Board may
make,  adopt,  alter,  amend and  repeal  the  By-Laws,  subject to the right of
shareholders  to adopt,  alter,  amend and  repeal  By-Laws  made by the  Board;
however,  the  affirmative  vote of 60% of the  voting  power of the  issued and
outstanding  shares  entitled to vote thereon is required to effect an amendment
or repeal of or adoption of a provision  inconsistent with the NSS By-Laws,  and
if  there  is  an  Interested  Shareholder,  such  60%  vote  must  include  the
affirmative  vote of not less than  two-thirds of the voting power of the issued
and outstanding  shares entitled to vote thereon held by shareholders other than
the Interested Shareholder. 


     SUMMIT.  As discussed above,  the Restated  Certificate of Incorporation of
Summit requires that certain  provisions  relating to increases in the number of
directors  (which  number may also be  increased  by the Board),  changes to the
classified  board provision and changes to the provision  requiring that actions
by shareholders be


                                       37


<PAGE>


effected  at an annual or  special  meeting  or by  unanimous  written  consent,
receive the affirmative  vote of holders of 80% of the combined voting shares of
Summit,  voting as a single class.  The By-Laws of Summit provide for amendments
upon  two-thirds  vote of the Board of Directors.  Under the New Jersey Business
Corporation  Act,  by-laws  made by a  corporation's  board  may be  altered  or
repealed and new by-laws made by the shareholders.



REMOVAL OF DIRECTORS


     NSS. Under the NSS Certificate of  Incorporation,  any individual  director
may be removed for cause by the affirmative vote of the holders of two-thirds of
the directors then in office. The NSS By-Laws further provide that directors may
be  removed  for cause in  accordance  with the CBCA and that the  office of any
director who fails to attend six consecutive  meetings of the Board shall become
vacant if the  majority of the Board  determines  such  absence was without good
cause.

     SUMMIT.  The Summit  Restated  Certificate  of  Incorporation  contains  no
specific  provisions  with  respect  to  removal of  directors  (other  than for
directors  elected by  Preferred  Shareholders).  Under the New Jersey  Business
Corporation Act, with respect to a classified board, directors may be removed by
shareholders  for cause only, by the  affirmative  vote of the majority of votes
cast by the holders entitled to vote thereon.


AUTHORIZED SHARES


     NSS. NSS has 7,000,000  authorized  shares of NSS Common and 500,000 shares
of Serial Preferred Stock, $.01 par value,  ("Serial Preferred") of which 50,000
shares  have  been  designated  Series A Junior  Participating  Preferred  Stock
("Series A  Preferred)  and reserved  for  issuance  under the NSS  Shareholders
Rights Plan.  As of June 30,  1998,  there were  2,378,085  shares of NSS Common
outstanding.  NSS's Certificate of Incorporation does not provide for preemptive
rights or cumulative voting to attach to the ownership of NSS Common.


     SUMMIT. The Restated  Certificate of Incorporation of Summit authorizes the
issuance  of  390,000,000  shares  of  Summit  Common  and  6,000,000  shares of
preferred  stock,  no par value. As of June 30, 1998,  there were  approximately
173,934,000  shares of Summit Common  outstanding and 1,500,000 shares of Summit
Series R Preferred created in Summit's Restated Certificate of Incorporation for
issuance under the Shareholder Rights Plan of Summit.  The Restated  Certificate
of Incorporation of Summit and the New Jersey Business Corporation Act authorize
the Summit  Board to amend the Restated  Certificate  of  Incorporation  without
shareholder  concurrence to divide the authorized shares of preferred stock into
series,  to  determine  the  designations  and the  number of shares of any such
series, and to determine the relative voting, dividend, conversion,  redemption,
liquidation  and other rights,  preferences  and  limitations  of the authorized
shares of preferred  stock.  No  preemptive  rights  attach to the  ownership of
Summit Common.


INDEMNIFICATION; LIMITATION OF LIABILITY


     NSS.  Article V of NSS's  By-Laws  provides  that NSS shall  indemnify  the
directors,  officers,  employees and agents to the maximum  extent  permitted by
and/or required by the CBCA. The NSS By-Laws  specifically  incorporate  certain
provisions of the CBCA relating to indemnification as from time to time amended.
Article IX of NSS's  Certificate  of  Incorporation  provides  that the personal
liability of a director of NSS to NSS or its  shareholders  for monetary damages
for breach of duty owed as a director  is limited to the amount of  compensation
received  during the year of the  violation  unless  (1) the  breach  involved a
knowing and culpable  violation of law by the director;  (2) the breach  enabled
the director or an "associate" (as that term is defined in Section 33-843 of the
Connecticut General Statutes) to receive an improper personal economic gain; (3)
the breach showed a lack of good faith and  conscious  disregard for the duty of
the director to NSS under circumstances in which the director was aware that his
or her conduct or omission  created an  unjustifiable  risk of serious injury to
NSS; (4) the breach constitutes a sustained and unexcused pattern of inattention
that  amounted  to an  abdication  of the  director's  duties to NSS; or (5) the
breach  created  liability  under  Section  33-757  or  Section  36a-58  of  the
Connecticut General Statutes.


                                       38

     SUMMIT. Summit's By-Laws provide that corporate agents (which term includes
directors,  officers  and  employees)  of Summit shall be  indemnified  and held
harmless by Summit to the fullest extent  authorized by the laws of the State of
New Jersey against  expenses and liabilities  arising in connection with actions
performed  by the  corporate  agent on  behalf  of Summit  and that  Summit  may
maintain  insurance  for  corporate  agents  against  liabilities  and expenses.
Summit's Restated  Certificate of Incorporation limits the personal liability of
a director or officer for damages for breach of any duty owned to the company or
its  shareholders  except for  liability for breach of duty based upon an act or
omission:  (i) in breach of such person's duty of loyalty to the  corporation or
its shareholders, (ii) not in good faith or involving a knowing violation of the
law,  or (iii)  resulting  in receipt  by such  person of an  improper  personal
benefit.


COMPARISON OF CORPORATION LAWS



     APPRAISAL RIGHTS IN MERGER OR CONSOLIDATION.  Under New Jersey  corporation
law,  unless a certificate of  incorporation  otherwise  provides,  a dissenting
shareholder of a New Jersey  corporation that is a party to a consolidation,  or
that is not the  surviving  corporation  in a merger,  or that is the  surviving
corporation in a merger  requiring  shareholder  approval,  has appraisal rights
with respect to any shares other than (1) shares listed on a national securities
exchange  or held of record by not less that  1,000  holders,  and (2) shares in
exchange  for  which,  pursuant  to the plan of  merger  or  consolidation,  the
shareholder  will  receive  cash  and/or  securities  which  will be listed on a
national  securities  exchange or held of record by not less than 1,000 holders.
Summit's Restated  Certificate of Incorporation  contains nothing which provides
otherwise.   Connecticut  law  provides   dissenters'  rights  of  appraisal  to
shareholders  of a  corporation,  such as  NSS,  in the  event  of a  merger  or
consolidation or similar transaction. If a shareholder properly exercises his or
her rights as an objecting shareholder, he or she will have the right to be paid
"fair value" of his or her shares based,  initially,  on the company's estimated
fair value of the shares.  If a shareholder  and the company do not agree on the
fair value of his or her shares,  the dissenting  shareholder  may submit to the
company  his or her own  estimate  of the fair  value  rejecting  the  company's
estimated  fair value offer.  The company must then commence a proceeding in the
Connecticut  Superior  Court  for the  judicial  district  where  the  company's
principal office is located to determine the fair value of the shares. The court
shall determine the fair value of the shares immediately before  effectuation of
the  Reorganization,  exclusive  of  any  element  of  value  arising  from  the
expectation or  accomplishment of the proposed  transaction.  The court may also
order the payment of interest  and/or certain costs and expenses under equitable
principles. See "THE REORGANIZATION - Dissenters' Rights." 

     APPRAISAL  RIGHTS  RELATING  TO  DISPOSITION  OF  ASSETS.  Under New Jersey
corporation  law,  a  dissenting  shareholder  in a New Jersey  corporation  has
appraisal rights in the case of any sale,  lease,  exchange or other disposition
of all or substantially all of the assets of the corporation not in the usual or
regular  course of  business as  conducted  by the  corporation  (other than for
certain  transfers  of  assets  of a  wholly  owned  subsidiary  by  the  parent
corporation),   except,   unless  the  certificate  of  incorporation   provides
otherwise,  with respect to (1) shares listed on a national  securities exchange
or held of record by not less than 1,000 holders, or (2) a transaction  pursuant
to a plan of dissolution of the corporation  which provides for the distribution
of  substantially  all of its net  assets  to  shareholders  according  to their
interests  within one year,  where such  transaction  is wholly for cash  and/or
securities  which will be listed on a national  securities  exchange  or held of
record by not less than 1,000  holders,  or (3) a sale  pursuant to court order.
The Connecticut  dissenters right statute  discussed in the preceding  paragraph
also applies in the event of the sale of substantially  all of the property of a
corporation,  other  than  pursuant  to a  court  order  or a plan  approved  by
shareholders  which provides that all of the net proceeds will be distributed to
shareholders within one year.


     CLASS VOTING ON MERGER OR CONSOLIDATION.  Under New Jersey corporation law,
any class or series of shares  shall be  entitled to vote as a class if the plan
of merger or  consolidation  contains  any  provisions  that,  if contained in a
proposed charter amendment, would entitle the class or series to vote as a class
on the amendment.  Connecticut  corporation law contains a similar  provision on
class voting on a plan of merger. 

     SOURCE OF DIVIDENDS. Under New Jersey corporation law, dividends may not be
paid if, after giving effect to the dividend,  either (1) the corporation  would
be unable  to pay its debts as they  become  due in the  ordinary  course of its
business  or (2) the  corporation's  total  assets  would be less than its total
liabilities.  Under Connecticut corporation law, dividends may be paid if, after
giving effect thereto, the corporation is able to pay its debts


                                       39


<PAGE>


as they become due in the usual  course of business  and the total assets of the
corporation  exceed its total  liabilities,  including amounts needed to satisfy
preferential rights of other shareholders.

     SHAREHOLDER  APPROVAL  OF MERGERS  AND  CONSOLIDATIONS.  While  shareholder
approval of a merger or consolidation  is generally  required under both the New
Jersey and the  Connecticut  corporation  laws, the New Jersey  corporation  law
provides that,  unless otherwise  provided in the  corporation's  certificate of
incorporation,  approval of the  shareholders  of a surviving  corporation  in a
merger is not  required if (i) the plan of merger does not make an  amendment of
the  certificate  of  incorporation  of the  surviving  corporation  that  would
otherwise require shareholder approval,  (ii) the shares outstanding immediately
before the effectiveness of the merger are not changed by the merger,  and (iii)
the  number of voting or  participating  shares  outstanding  (including  shares
issuable  upon  conversion  of other  securities  or upon  exercise of rights or
warrants issued pursuant to the merger) after the merger, after giving effect to
the  merger,  will  not  exceed  by more  than  40% the  number  of  voting  and
participating  shares,  as  the  case  may  be,  of  the  surviving  corporation
outstanding immediately prior to the merger. The Connecticut corporation law has
a generally  similar  provision but the percentage  threshold is 20% rather than
40%.

     Under the New Jersey  corporation  law,  unless  otherwise  provided in the
corporation's  certificate  of  incorporation,  a merger  requiring  shareholder
approval  must be  approved by the  majority  of the votes cast by  shareholders
entitled to vote thereon.  Under  Connecticut  corporation law, unless otherwise
provided in the certificate of  incorporation or by the  corporation's  board of
directors, in the case of a corporation incorporated after January 1, 1997 (such
as NSS), a merger requiring  shareholder  approval requires the affirmative vote
of a majority of the votes entitled to be cast by each voting group.


     SHAREHOLDER  APPROVAL OF ASSET SALES.  Under New Jersey  corporation law, a
sale of all or substantially  all of a corporation's  assets outside the regular
course of  business  requires  the  approval of the board of  directors  and the
affirmative  vote of a majority  of the votes cast by  shareholders  entitled to
vote thereon.  The Restated Certificate of Incorporation of Summit provides that
the  Board of  Directors  of  Summit  may sell all the  rights,  franchises  and
property of the company as an entirety  with the approval of  two-thirds  of the
outstanding  shares.  Under  Connecticut  corporation  law,  a  sale  of  all or
substantially all of the assets of a corporation  incorporated  after January 1,
1997 requires the approval of the holders of a majority of the outstanding stock
of the corporation entitled to vote thereon.

     POWER TO ADOPT, AMEND OR REPEAL BY-LAWS.  Under New Jersey corporation law,
the power to adopt,  amend and repeal  by-laws of a corporation is vested in the
Board of  Directors  unless such power is reserved  to the  shareholders  in the
certificate of incorporation,  but by-laws made by the Board of Directors may be
amended  and  repealed  and new  by-laws  adopted  by the  shareholders  and the
shareholders  may  prescribe  in such  by-laws  that the  Board may not amend or
repeal by-laws approved by shareholders.  Under Connecticut corporation law, the
board  of  directors  has the  power to  adopt,  amend or  repeal  by-laws  of a
corporation unless: (1) the corporation's  certificate of incorporation reserves
power to the corporation's shareholders, or (2) the shareholders, in amending or
repealing a particular  by-law provide expressly that the board of directors may
not amend or repeal that by-law. Furthermore, Connecticut corporation law allows
a corporation's  shareholders  to amend or repeal a  corporation's  by-laws even
though the by-laws may also be amended or repealed by its board of directors.

     ACTION BY SHAREHOLDERS  BY WRITTEN CONSENT IN LIEU OF A MEETING.  Under New
Jersey  corporation  law,  except as  otherwise  provided  in a  certificate  of
incorporation,  any action  (other than the election of  directors)  required or
permitted  to be taken at a meeting of the  corporation's  shareholders,  may be
taken without a meeting upon the written consent of shareholders  who would have
been entitled to cast the minimum number of votes that would have been necessary
to take such action at a meeting at which all shares  entitled  to vote  thereon
were present and voted. The annual election of directors,  if not conducted at a
shareholders'  meeting, may only be effected by unanimous written consent. Under
New  Jersey   corporation   law,  a  shareholder  vote  on  a  plan  of  merger,
consolidation or sale of substantially all of the assets of the corporation,  if
not conducted at a shareholders'  meeting,  may only be effected by either:  (i)
unanimous written consent of all shareholders entitled to 


                                       40


<PAGE>


vote on the matter with advance notice to any other shareholders, or (ii) unless
otherwise  provided in the corporation's  certificate of incorporation,  written
consent of shareholders  who would have been entitled to cast the minimum number
of votes necessary to authorize such action at a meeting,  together with advance
notice to all other  shareholders.  As previously  discussed,  Summit's Restated
Certificate of  Incorporation  permits action by written  consent only where the
consent is unanimous.  Connecticut corporation law, except as otherwise provided
in a company's  certificate  of  incorporation,  permits any action which may be
taken at a meeting of shareholders to be taken without a meeting as follows: (i)
by consent in writing,  setting forth the action so taken or to be taken, signed
by all of the  persons  who would be  entitled  to vote  upon  such  action at a
meeting,  or by their duly authorized  attorneys;  or (ii) if the certificate of
incorporation so provides, by consent in writing, setting forth the action to be
taken,  signed by persons  holding such designated  proportion,  not less than a
majority,  of the voting power of shares, or the shares of any particular class,
entitled  to vote  thereon or to take such  action,  as may be  provided  in the
certificate of incorporation,  or their duly authorized  attorneys;  except that
directors  may not be  elected  by action of  shareholders  without a meeting of
shareholders  other than by unanimous written consent,  or pursuant to a plan of
merger.


     REMOVAL OF DIRECTORS.  Under New Jersey corporation law, one or more of all
directors  of a  corporation  may be  removed  for  cause or,  unless  otherwise
provided in the certificate of  incorporation,  without cause by shareholders by
the affirmative  vote of the majority of the votes cast by the holders of shares
entitled  to vote  thereon.  Unless  otherwise  provided in the  certificate  of
incorporation,  shareholders  of a  corporation  whose  board  of  directors  is
classified  (such as Summit) may not remove a director  except for cause.  Under
Connecticut corporation law any director or the entire board of directors may be
removed,  with or without cause, by the holders of a majority of the shares then
entitled  to  vote  at an  election  of  directors  unless  the  certificate  of
incorporation  provides that  directors  may be removed only for cause.  The NSS
Certificate of Incorporation  provides for removal for cause only, by two-thirds
vote of directors.


     SPECIAL MEETINGS OF SHAREHOLDERS. Under New Jersey corporation law, special
meetings of shareholders may be called by the President or Board of Directors of
the  corporation,  or by such  other  officers,  directors  or  shareholders  as
provided  for in the  by-laws.  In  addition,  holders of not less than 10% of a
corporation's  voting  stock may apply to the New Jersey  Superior  Court for an
order directing a special meeting of shareholders to be held. Under  Connecticut
corporation  law, special meetings of stockholders may be called by the Board of
Directors  or by such  person or persons  as may be  authorized  by a  company's
certificate  of  incorporation   or  the  by-laws,   and  with  respect  to  the
corporations  with voting stock  registered  under the Exchange Act which had no
10%  shareholders  as of February 1, 1988 (such as NSS),  by holders of not less
than 35% of the corporation's voting stock.


     DEFACTO MERGER.  Under New Jersey  corporation law,  shareholders  have the
same voting and dissent and appraisal  rights as if they were  shareholders of a
surviving  corporation in a reorganization,  if (1) voting shares outstanding or
issuable after the transaction exceed by more than 40% voting shares outstanding
before the transaction or (2) shares entitled to participate  without limitation
in  distributions  outstanding or issuable after the transaction  exceed by more
than 40% such shares outstanding before the transaction. Connecticut corporation
law does not contain a comparable provision.


     SHAREHOLDERS'  DERIVATIVE  ACTIONS.  New Jersey  corporation  law  contains
certain  provisions  that have the effect of  discouraging  derivative  actions.
Specifically,  New Jersey law authorizes the court having  jurisdiction over the
action  to award  reasonable  expenses  and  attorney's  fees to the  successful
defendants  in a  derivative  action upon a finding  that the action was brought
without reasonable cause. In addition, the corporation may require the plaintiff
or plaintiffs to give security for the reasonable expenses, including attorneys'
fees, that may be incurred by the  corporation or by other named  defendants for
which the  corporation  may become legally liable if plaintiff or plaintiffs are
holders of less than 5% of the outstanding shares of any class or series of such
corporation (or voting trust  certificates  therefor) unless the shares or trust
certificates  so held  have a market  value in excess  of  $25,000.  Connecticut
corporate  law  also  contains  a  provision  authorizing  the  court  to  award
reasonable expenses,  including attorneys' fees to the defendant in a derivative
action if the court  finds  that the  proceeding  was  commenced  or  maintained
without reasonable cause or for an improper purpose.


                                       41


<PAGE>


     INSPECTION  OF BOOKS AND  RECORDS.  Under New  Jersey  corporation  law,  a
shareholder of record for at least 6 months immediately  preceding his demand or
any holder (or a person  authorized  on behalf of such holder) of at least 5% of
the  outstanding  shares of any class or series  shall have the right to examine
for any proper purpose the minutes of the proceedings of shareholders and record
of shareholders. Furthermore, upon establishing a proper purpose and receiving a
court order a shareholder may examine the books and records of account,  minutes
and records of shareholders of a corporation. Under Connecticut corporation law,
upon five business days notice a shareholder  (including a beneficial  owner) is
entitled to inspect and copy the corporation's  certificate of incorporation and
by-laws (and any  amendments  thereto),  board  resolutions  creating  series or
classes  of shares and  fixing  rights,  preferences  and  limitations  thereto,
minutes of  shareholders  meetings  and  actions  by consent  for the past three
years, written  communications to shareholders,  including financial statements,
for the past 3 years,  names and business  addresses of directors  and officers,
and the  corporation's  most recent  annual  report filed with the  Secretary of
State,  minutes of meetings of  directors,  committees,  accounting  records and
shareholder records, provided that the shareholder demand is in writing, is made
in good faith, states a proper purpose,  describes with reasonable particularity
the purpose and records to be inspected and such records are directly related to
such purpose.  Shareholders also have the right, upon written demand, to inspect
the shareholders list beginning two days after notice of a shareholders  meeting
for which the list was proposed, continuing through the meeting.


     ANTI-TAKEOVER  STATUTES.  New  Jersey has  adopted a type of  anti-takeover
statute  known  as  a  "business  combination"  statute.   Subject  to  numerous
qualifications and exceptions,  the statute prohibits an interested  stockholder
of a corporation from effecting a business  combination with the corporation for
a period of five years unless the  corporation's  board approved the transaction
prior to the  stockholder  becoming an interested  stockholder,  the transaction
receives the approval of two-thirds of the voting stock of the  corporation  not
beneficially  owned by the  interested  stockholder,  or the  transaction  meets
certain  minimum  financial  terms.  An "interested  stockholder"  is defined to
include  any  beneficial  owner  of  10% or  more  of the  voting  power  of the
outstanding  voting stock of the  corporation  and any affiliate or associate of
the corporation who within the prior five-year  period has at any time owned 10%
or more of the voting power. The term "business  combination" is defined broadly
to include,  inter alia, (1) the merger or consolidation of the corporation with
the  interested  stockholder  or any  corporation  that  after  such  merger  or
consolidation would be an affiliate or associate of the interested  stockholder,
(2) the sale, lease, exchange,  mortgage,  pledge, transfer or other disposition
to an interested  stockholder  or any  affiliate or associate of the  interested
stockholder of 10% or more of the  corporation's  assets; or (3) the issuance or
transfer to an  interested  stockholder  or any  affiliate  or  associate of the
interested  stockholder of 5% or more of the aggregate market value of the stock
of the  corporation.  The  effect of the  statute  is to  protect  non-tendering
post-acquisition  minority  shareholders  from  mergers  in which  they  will be
"frozen out" after the merger, by prohibiting  transactions in which an acquiror
could  favor  itself at the  expense of  minority  stockholders.  The New Jersey
statute does not apply to New Jersey  corporations that do not have either their
principal  executive offices or significant  business  operations located in New
Jersey.


     Connecticut  corporation law provides that any "business combination" must,
with  certain  exceptions,  be  approved  by the  board  of  directors  and  the
affirmative  vote of at least  the  holders  of 80% of the  voting  power of the
outstanding  shares  of  voting  stock of the  corporation  and the  holders  of
two-thirds of the voting power of the outstanding  shares of voting stock of the
corporation  other than  voting  stock held by the  interested  shareholder  (as
defined  below)  who is,  or whose  affiliate  or  associate  is, a party to the
business  combination  or held by an affiliate  or  associate of the  interested
shareholder.  A "business  combination"  is  generally  defined in the CBCA,  to
include (A) any merger,  consolidation or share exchange with (i) any interested
shareholder (as defined below) or (ii) any other domestic or foreign corporation
whether or not itself an interested shareholder,  which is, or after the merger,
consolidation  or share  exchange  would be, an  affiliate  or  associate  of an
interested   shareholder  that  was  an  interested  shareholder  prior  to  the
transaction;  (B) any sale, lease, exchange, mortgage, pledge, transfer or other
disposition,  other than in the usual and  regular  course of  business,  in one
transaction  or a series of  transactions  in any  twelve-month  period,  to any
interested   shareholder  or  any  affiliate  or  associate  of  any  interested
shareholder,  other than the  corporation,  or any of its  subsidiaries,  of any
assets of the  corporation or any  subsidiary  having an aggregate book value of
10%  or  more  of the  total  market  value  of the  outstanding  shares  of the
corporation  or  of  its  net  worth,  (C)  the  issuance  or  transfer  by  the
corporation, or any


                                       42


<PAGE>


subsidiary,  of any equity securities of the corporation or any subsidiary which
have  an  aggregate  value  of 5% or  more  of the  total  market  value  of the
outstanding shares of the corporation to any "interested shareholder" (generally
defined  as the  beneficial  owner  of 10% or more of the  voting  power  of the
outstanding  shares  of  voting  stock of a  corporation)  or any  affiliate  or
associate of any interested shareholder,  (D) the adoption of any resolution for
the liquidation or dissolution of the corporation or any subsidiary  proposed by
or on behalf or an interested  shareholder  or any affiliate or associate of any
interested  shareholder,  other than the corporation or any of its subsidiaries;
or (E) any  reclassification  of securities,  as defined  therein,  in each case
subject to certain  limitations).  This  supermajority  voting  provision is not
applicable if (A) all of the fair price and  procedural  conditions set forth in
Section 33-842(b) of the CBCA are met or (B) the board of directors approves the
business  combination  prior to the time the  interested  shareholder  became an
interested  shareholder,  unless  the  certificate  of  incorporation  otherwise
provides.


     In addition to the "business combination" statute described above, the CBCA
further provides that a resident  domestic  corporation (as defined in the CBCA)
may not engage in a business  combination  (which is  defined  similarly  to the
definition set forth above) with an interested  shareholder of such  corporation
for a period of five years  following the date that the  interested  shareholder
became such unless such  business  combination  or the purchase of stock made by
such interested person on the date that the interested  shareholder  became such
is approved by the board of  directors of the  corporation  and by a majority of
the  nonemployee  directors,  of which there must be at least two,  prior to the
interested shareholder's stock acquisition date. The foregoing provisions do not
apply to certain  excepted  transactions  listed in Section  33-845 of the CBCA.


     Under New Jersey  corporation law, a director of a New Jersey  corporation,
in discharging his or her duties to the corporation,  and in determining what he
or she reasonably believes to be in the best interest of the corporation may, in
addition to considering the effects of any action on shareholders,  consider any
of the following:  (a) the effects of the action on the corporation's employees,
suppliers,  creditors  and  customers;  (b) the  effects  of the  action  on the
community in which the  corporation  operates;  and (c) the long-term as well as
the short-term  interest of the corporation and its shareholders,  including the
possibility   that  these   interests  may  best  be  served  by  the  continued
independence of the corporation.  Determinations resulting in the rejection of a
proposal  or offer to acquire  the  corporation  are  expressly  covered by this
provision of the New Jersey Business  Corporation Act. The Connecticut  Business
Corporation Law contains a similar "other constituency" provision with regard to
mergers, sales of assets and other business combinations.


     INDEMNIFICATION.  Under the New Jersey  corporation  law, a corporation may
indemnify  any person who is or was a director,  officer,  trustee,  employee or
agent of the corporation, or is or was serving at the request of the corporation
as a  director,  officer,  trustee,  employee  or agent of another  corporation,
partnership,  joint venture,  sole  proprietorship,  trust or other  enterprise,
against his reasonable  expenses (including counsel fees) in connection with any
pending,  threatened  or  completed  proceeding  by  or  in  the  right  of  the
corporation  to procure a judgment  in its favor which  involves  such person by
reason of his corporate agent status,  if he or she acted in good faith and in a
manner  he or she  reasonably  believed  to be in or  not  opposed  to the  best
interests  of the  corporation.  However,  no  indemnification  shall be made in
respect of any claim,  issue or matter as to which such  person  shall have been
adjudged to be liable to the  corporation,  unless,  and only to the extent that
the  Superior  Court of New  Jersey or the court in which  such  proceeding  was
brought shall determine that,  despite the adjudication of liability but in view
of all the  circumstances  of the case,  such  person is fairly  and  reasonably
entitled to indemnity for such expenses that the Superior Court of New Jersey or
such other court shall deem  proper.  In  connection  with any other  proceeding
involving  the  corporate  agent by reason  of his  being or having  been such a
corporate  agent,  a  corporation  may  indemnify  any such  person  against his
reasonable expenses and liabilities in connection with any such proceeding if he
or she acted in good faith and in a manner he or she  reasonably  believed to be
in or not opposed to the best interests of the corporation, and, with respect to
any criminal proceeding, he or she had no reasonable cause to believe his or her
conduct was  unlawful.  New Jersey  corporation  law requires that a corporation
shall  indemnify any such person against  expenses to the extent such person has
been  successful on the merits or otherwise in any of the foregoing  proceedings
or in the defense of any claim,  issue or matter therein,  and provides that any
such  person  may  apply  to a court  for an  award  of  indemnification  by the
corporation if the corporation has failed or refused to provide  indemnification
as provided under the statute.



                                       43


<PAGE>


     New Jersey  corporation  law also  permits a  corporation  to purchase  and
maintain insurance on behalf of any such person against any expenses incurred in
any proceeding and any liabilities asserted against such person by reason of his
or her corporate  agent status,  whether or not the  corporation  would have the
power indemnify such person under the statute.

     Similarly,  Connecticut  Corporation  law provides that a  corporation  may
indemnify  directors,  officers,  employees  and agents with  respect to certain
actions  (including  a suit by or in the right of the  corporation  to procure a
judgment  in its  favor)  by  reason  of  the  fact  that  he or she is or was a
director,  officer,  employee or agent against  expenses  (including  attorneys'
fees),  judgments,  fines and amounts paid in settlement actually and reasonably
incurred  by him or her in  connection  with the defense or  settlement  of such
action,  suit or proceeding  if he or she  conducted  himself or herself in good
faith and he or she reasonably believed (a) in the case of conduct in his or her
official capacity with the corporation,  that his or her conduct was in its best
interests and (b) in all other cases, that his or her conduct was not opposed to
its best interests and, with respect to any criminal  action or proceeding,  had
no reasonable cause to believe his or her conduct was unlawful.  With respect to
derivative actions,  however, no indemnification shall be made in respect of any
claim,  issue or matter as to which such person  shall have been  adjudged to be
liable to the corporation  unless and only to the extent that the court in which
such action or suit was brought shall determine upon adjudication  that, despite
the adjudication of liability but in view of all the  circumstances of the case,
such person is fairly and  reasonably  entitled to  indemnity  for such  expense
which the court shall deem proper.  Connecticut  corporation law requires that a
corporation  shall indemnify any such person against expenses to the extent such
person has been  successful  on the merits or otherwise in any of the  foregoing
proceedings or defense of any such claims.

     The corporation law permits a Connecticut  business corporation to purchase
and maintain insurance on behalf of any person who is or was director,  officer,
employee or agent of the  corporation,  against any liability  asserted  against
such person and incurred by him or her in any such  capacity,  or arising out of
his  status as such,  whether  or not the  corporation  would  have the power to
indemnify such person.


     Both New Jersey and  Connecticut  corporation  law  permit  advancement  of
expenses incurred by directors and officers.


     LIMITATION OF DIRECTOR AND OFFICER  LIABILITY.  New Jersey  corporation law
provides that directors and members of any committee  designated by the board of
directors are not liable to a corporation or its  shareholders if acting in good
faith in discharging  their duties they rely upon (i) the opinion of counsel for
the  corporation,  (ii) written  reports setting forth financial data concerning
the  corporation and prepared by an independent  public  accountant or certified
public accountant or firm of such accountants, (iii) financial statements, books
of account or reports of the  corporation  represented  to them to be correct by
the  president,  the officer of the  corporation  having  charge of its books of
account,  or the person  presiding  at a meeting of the board,  or (iv)  written
reports of committees of the board.  The Connecticut  corporation law contains a
similar  provision  which  provides  that  members of a board of  directors  are
entitled to rely in good faith upon the records of the corporation and upon such
information, opinions, reports or statements presented to the corporation by any
of the  corporation's  officers  or  employees,  or  committees  of the board of
directors,  or by any other person as to matters the member reasonably  believes
are within such other person's professional or expert competence.

     The New Jersey  corporation  law further  provides that the  certificate or
incorporation of domestic  corporations  may contain  provisions which limit the
personal  liability  of  directors  and  officers,  in whole or in part,  to the
corporation or its  shareholders  for damages for breach of any duty owed to the
corporation  or its  shareholders  except for acts or omissions (i) in breach of
the  director's  or  officer's  duty  of  loyalty  to  the  corporation  or  its
shareholders, (ii) not in good faith or involving a knowing violation of law, or
(iii) resulting in receipt by such person of an improper personal benefit.  With
respect to the foregoing  provisions,  the New Jersey  corporation  law provides
that the duty of loyalty is breached by an act or omission  known or believed by
a director or officer to be contrary to the best interests of the corporation or
its shareholders in connection with matters in which the director or officer has
a material  conflict of  interest.  Under the CBCA,  directors  and  officers of
Connecticut  corporations  are not liable for any actions  taken as directors or
officers,  or any failure to take action,  if they acted, or failed to act, in a
manner  consistent  with the  standard of care  established  for  directors  and
officers under Connecticut law. Under Connecticut  corporation law a director or
officer must exercise his or her duties: (i) in


                                       44


<PAGE>


good faith;  (ii) with the care an ordinarily  prudent person in a like position
would  exercise  under  similar  circumstances;  and (iii) in a manner he or she
reasonably believes to be in the best interest of the corporation.




                                 SUMMIT BANCORP


DESCRIPTION OF BUSINESS

     Summit  commenced  operations on October 1, 1970 as a bank holding  company
registered  under the BHC Act.  Summit  owns two bank  subsidiaries  and several
active non-bank  subsidiaries.  At June 30, 1998, Summit had total  consolidated
assets of $31.1  billion  on the basis of which it  ranked  as the  largest  New
Jersey-based bank holding company.

     The bank  subsidiaries  engage in a general banking  business.  Summit Bank
(Hackensack,   NJ)  is  Summit's   largest  bank   subsidiary,   accounting  for
approximately  91.5% of Summit's  total  consolidated  assets at June 30,  1998.
Summit's  non-bank   subsidiaries  engage  primarily  in  securities  brokerage,
insurance  brokerage,  venture capital  investment,  commercial finance lending,
lease financing, asset-based lending production, letter of credit issuance, data
processing and reinsuring credit life and disability  insurance policies related
to consumer loans made by the bank subsidiaries.

     The bank  subsidiaries  operated 450 banking offices located in major trade
centers and suburban areas in New Jersey and  Pennsylvania  as of June 30, 1998.
The  following  table lists,  as of June 30,  1998,  each bank  subsidiary,  the
location in New Jersey or  Pennsylvania of its principal  office,  the number of
its banking offices and, in thousands of dollars, its total assets and deposits.
Both the New Jersey and Pennsylvania subsidiaries are state banks and members of
the Federal Reserve System.

     Summit is a legal entity separate and distinct from its subsidiaries. There
are  various  legal  limitations  on the extent to which a bank  subsidiary  may
finance or otherwise supply funds to Summit or its nonbank  subsidiaries.  Under
federal law, no bank subsidiary may, subject to certain limited exceptions, make
loans or extensions of credit to, or  investments in the securities of Summit or
its non-bank  subsidiaries  or take their  securities as collateral for loans to
any  borrower.  Each bank  subsidiary  is also  subject to  collateral  security
requirements for any loans or extensions of credit permitted by such exceptions.
In addition,  certain bank regulatory  limitations  exist on the availability of
subsidiary bank  undistributed net assets for the payment of dividends to Summit
without  the prior  approval  of the bank  regulatory  authorities.  The Federal
Reserve Act,  which  affects both bank  subsidiaries,  restricts  the payment of
dividends  in any calendar  year to the net profit of the current year  combined
with  retained  net  profits  of  the  preceding  two  years.  Each  bank,  as a
state-chartered bank, may declare a dividend only if, after payment thereof, its
capital would be unimpaired and its remaining  surplus would equal 50 percent of
its capital  (New  Jersey) or its surplus  would not be reduced  (New Jersey and
Pennsylvania).  At June 30, 1998, the total undistributed net assets of Summit's
subsidiary  banks were $2.4 billion of which $106.7 million was available  under
the most restrictive limitations for the payment of dividends to Summit.

                      DESCRIPTION OF SUMMIT CAPITAL STOCK

     Summit is presently authorized to issue 390,000,000 shares of Summit Common
and 6,000,000 shares of Preferred Stock, without par value ("Summit Preferred").
As of June 30, 1998 there were approximately 173,934,000 shares of Summit Common
outstanding  and  1,500,000  shares of Summit  Series R Preferred  designated in
Summit's  Restated  Certificate of Incorporation and reserved for issuance under
the Summit Rights Plan (as defined herein).  On the date of this Proxy Statement
- -- Prospectus there were no shares of Summit Preferred outstanding.  Pursuant to
the New Jersey Business  Corporation  Act, the Summit Board has authority to set
the terms and conditions of the authorized but unissued Summit Preferred. Summit
may issue any  authorized  Summit Common and Summit  Preferred  without  further
shareholder vote, unless such a vote is required for a particular transaction by
applicable law or stock exchange  rules,  including  rules of the NYSE, on which
the Summit Common is presently listed.  The issuance of additional Summit Common
or Summit  Preferred,  including Summit Preferred that might be convertible into
Summit Common, may, among other things, affect the earnings per share applicable
to existing  Summit Common and the equity and voting rights of existing  holders
of Summit Common.

     The following summary does not purport to be complete and is subject in all
respects to the  applicable  provisions of the New Jersey  Business  Corporation
Act, Summit's Restated Certificate of Incorporation and Summit's
Rights Plan.


COMMON STOCK

     The rights of holders of Summit Common are subject to the preferences as to
dividends and liquidation rights and other prior rights, if any, of any class or
series of Summit Preferred that may be issued.  The holders of Summit Common are
entitled to one vote for each share with  respect to all  matters  voted upon by
shareholders,  including the election of directors,  and are entitled to receive
dividends  when,  as and if declared by the Summit  Board out of funds of Summit
legally  available  therefor.  Shares  of Summit  Common do not have  cumulative
voting rights; accordingly, at any Special meeting of Summit shareholders (or at
any special meeting of shareholders where an election of directors is conducted)
the  holders  of 50  percent  plus 1 of the shares  represented  at the  meeting
(provided a quorum is present)  can fill all  positions on the Summit Board that
are up for  election at such  meeting if they so choose and, in such event,  the
holders of the remaining  less than 50 percent of the shares will not be able to
fill any of such positions.  Summit has a classified  Board of Directors,  under
which  approximately  one-third of the  directors  are elected each year. In the
event of the  liquidation  of Summit,  holders of Summit  Common are entitled to
share  pro  rata in the  distribution  of  Summit's  assets  available  for such
purpose.  All  shares of Summit  Common  are fully  paid and  nonassessable.  No
preemptive  rights  attach to the  ownership  of Summit  Common and no  personal
liability is imposed on the holders  thereof by reason of the  ownership of such
shares. First Chicago Trust Company of New York is the transfer agent,  dividend
disbursing agent and registrar for the Summit Common.  Summit Bank  (Hackensack,
NJ) is the co-transfer agent.

     In April 1998, the Summit Board authorized the repurchase from time to time
of up to five percent,  or 8.9 million shares, of outstanding  Summit Common. In
addition,  the Summit Board has  authorized  the  repurchase of shares of Summit
Common for the Reorganization. Through June 30, 1998, Summit had repurchased 3.9
million shares of Summit Common  pursuant to its repurchase  program and for the
acquisition of NSS.


TRUST PREFERRED SECURITIES

     On March 20, 1997, Summit Capital Trust 1 ("Trust"),  a statutory  business
trust  created  under  the  laws  of the  State  of  Delaware  and  wholly-owned
subsidiary of Summit,  issued $150.0 million of 8.4% Capital Trust  Pass-through
Securities,  representing  undivided  beneficial  interests in the assets of the
Trust   ("Capital   Securities"),   and  $4.6  million  of  Common   Securities,
representing  undivided beneficial interests in the assets of the Trust ("Common
Securities")  (collectively,  the Capital  Securities and Common  Securities are
referred to as the "Trust  Securities").  The Trust used the  proceeds  received
from the sale of the Trust  Securities to purchase $154.6 million of 8.4% Junior
Subordinated   Deferrable   Interest   Debentures  due  2027  issued  by  Summit
("Subordinated


                                       46


<PAGE>


Debentures").  The Trust was  created  solely for the purpose of  investing  the
proceeds  received  from the sale of the Trust  Securities  in the  Subordinated
Debentures.  Summit has  guaranteed  that,  to the extent the Trust has received
certain payments from Summit, the Trust will distribute such funds.


SHAREHOLDER RIGHTS PLAN

     In August 1989,  Summit adopted a shareholder  rights plan ("Rights Plan"),
under which preferred stock purchase rights ("Rights") attached to Summit Common
outstanding as of the close of business on August 28, 1989. Holders of shares of
Summit  Common  issued  subsequent  to that date  receive  the Rights with their
shares.  Except as indicated below, each Right entitles the registered holder to
purchase from Summit one  one-hundred and fiftieth of a share of a new series of
Summit Preferred Stock,  designated the Series R Preferred Stock ("Summit Series
R  Preferred").  The  Rights  expire on August  16,  1999,  and are  subject  to
redemption   and   amendment   in  certain   circumstances.   The  Rights  trade
automatically  with shares of Summit  Common and become  exercisable  only under
certain circumstances as described below.

     In general, the Rights will become exercisable upon the earlier to occur (a
"Distribution  Date",  as defined in the Rights Plan) of the following:  (1) ten
days  following  a public  announcement  that a person  or  group  has  acquired
beneficial  ownership of 15% or more of the Summit  Common  outstanding  at that
time or voting securities of Summit representing 15% or more of the total voting
power of Summit (such person or group becoming an "Acquiring Person", as defined
in the Rights Plan) or (2) ten  business  days (or such later date as the Summit
Board may determine)  after the commencement of a tender offer or exchange offer
that would  result in a person or group  beneficially  owning 30% or more of the
outstanding  Summit Common or voting securities  representing 30% or more of the
total voting power of Summit.

     Generally, in the event a Distribution Date occurs by virtue of a person or
group  becoming an  Acquiring  Person  (other than  pursuant to an offer for all
outstanding  shares of Summit Common and other voting securities that the Summit
Board  determines to be fair to shareholders and otherwise in the best interests
of Summit),  each Right,  other than Rights owned by the Acquiring Person,  will
thereafter  entitle the holder to receive,  upon  exercise of the Right,  Summit
Series R Preferred  having a value equal to two times the exercise  price of the
Right.

     In  the  event  that  a  Distribution  Date  occurs  (under  either  of the
circumstances  described  above) and Summit is acquired in a  reorganization  or
other business combination, or more than 50% of Summit's assets or earning power
is sold or transferred,  each Right will thereafter  entitle the holder there to
receive,  upon the exercise of the Right,  common stock of the acquiror having a
value equal to two times the exercise price of the Right.

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

     The  foregoing  description  of the  Rights  Plan  does not  purport  to be
complete  and is  qualified  in its  entirety by  reference  to the terms of the
Rights Plan, which is more fully described in Summit's Registration Statement on
Form 8-A filed August 28, 1989.


                               NSS BANCORP, INC.


DESCRIPTION OF BUSINESS

     NSS  is a  Connecticut  chartered  bank  holding  company  whose  principal
operating subsidiary is NSS Bank, a Connecticut  chartered capital stock savings
bank. The only  significant  asset of NSS is its investment in the capital stock
of NSS Bank.

     NSS Bank conducts  business from eight offices  located in the  Connecticut
towns of Norwalk, Darien,  Fairfield,  Georgetown,  Wilton, and Westport, all of
which are part of Fairfield County,  Connecticut.  The principal business of NSS
Bank is to  attract  deposits  from  the  general  public,  to  extend  loans to
individuals in the


                                       47


<PAGE>


community for the purchase or construction of one-to-four family residences,  to
make consumer installment loans, to invest in securities, and to provide typical
consumer  banking  services.  NSS Bank also makes loans secured by  multi-family
(e.g.,  five or more units) and commercial real estate,  as well as construction
loans,  land  acquisition  and  development  loans  and,  to  a  lesser  extent,
commercial  business,  consumer and other loans. NSS Bank's principal sources of
income  are  interest  on loans  and  interest  and  dividends  on  investments,
primarily  U.S.  Government  agency  and  mortgage-backed  securities  and other
short-term  investments.  In recent years, NSS Bank has realized income from the
sale of loans and  mortgage-backed  and investment  securities  and, to a lesser
extent,  NSS Bank realizes  other  non-interest  income,  including  income from
service charges on deposit accounts, trust fees and credit card fees. NSS Bank's
deposits are insured by the Federal Deposit  Insurance  Corporation  ("FDIC") to
the maximum  extent  permitted  by law. The  principal  sources of funds for NSS
Bank's  activities are deposit  accounts,  amortization and prepayment of loans,
borrowings  from the  Federal  Home Loan Bank  (FHLB)  and funds  provided  from
operations.  NSS and NSS Bank are subject to regulation  by the Federal  Reserve
Board, the FDIC and the Connecticut Banking Commissioner.




                        DESCRIPTION OF NSS CAPITAL STOCK



COMMON STOCK


     NSS is presently  authorized  to issue  7,000,000  shares of NSS Common and
500,000 shares of Serial Preferred,  of which 50,000 have been designated Series
A Preferred.  As of June 30,  1998,  there were  2,378,085  shares of NSS Common
outstanding. 

     DIVIDENDS.  The  holders of NSS Common are  entitled  to receive  and share
equally  in such  dividends  as may be  declared  by the NSS  Board out of funds
legally available therefor.

     VOTING  RIGHTS.  The  holders of NSS Common  elect the NSS Board and act on
such other matters as are required to be presented to them under the CBCA, NSS's
Certificate of  Incorporation  or as are otherwise  presented to them by the NSS
Board.  Each holder of NSS Common is entitled to one vote per share.  Holders of
NSS Common may not cumulate  votes.  Directors of NSS are elected by a plurality
of votes cast.


     PREEMPTIVE RIGHTS. Holders of NSS Common are not entitled to preemptive
rights with respect to any shares that may be issued.



SHAREHOLDERS' RIGHTS AGREEMENT

     On May 10,  1996 (the  "Declaration  Date"),  NSS Bank  declared a dividend
distribution of one NSS Right for each outstanding  share of common stock of NSS
Bank. The dividend was paid on May 28, 1996 to the  shareholders of record as of
the close of business on such date. The  description and terms of the NSS Rights
are set forth in a Rights  Agreement (the "Rights  Agreement")  between NSS Bank
and Chase Mellon Shareholder  Services,  LLC (the "Rights Agent"). In connection
with its reorganization  into a bank holding company structure in 1997, NSS Bank
assigned to NSS, and NSS assumed,  all rights and  obligations of NSS Bank under
the Rights  Agreement.  NSS capital stock was  substituted  in place of NSS Bank
capital  stock  under the Rights  Agreement.  When  exercisable,  each NSS Right
entitles  the  registered  holder  of  NSS  Common  to  purchase  from  NSS  one
one-hundredths  of a share of Series A Junior Preferred at a price of $40.00 per
one one-hundredths of a share, subject to adjustment.

     Until  such time that a person or group of persons  acquires a  controlling
interest  in NSS so as to be  deemed  an  Acquiring  Person  (the  "Distribution
Date"),  the NSS Rights will be  evidenced  by NSS Common  certificates  and NSS
Rights are transferred with and only with NSS Common. The transfer of any of the
common stock certificates  constitutes the transfer of the NSS Rights associated
with the common  stock  represented  by such  certificate.  The  purchase  price
payable,  and the number of Series A Preferred Shares of NSS or other securities
or property issuable,  upon exercise of the NSS Rights are subject to adjustment
from time to time to prevent dilution.  The number of outstanding NSS Rights and
the number of one  one-hundredths of a Series A Preferred issuable upon exercise
of each NSS Right are also  subject  to  adjustment,  prior to the  Distribution
Date.


                                       48


<PAGE>


     If NSS is acquired in a merger or other  business  combination,  the Rights
Agreement  requires that proper provisions be made by NSS so that each holder of
a NSS Right  shall  thereafter  have the  right to  receive,  upon the  exercise
thereof at the then  current  exercise  price of the NSS Right,  that  number of
shares of common stock of the surviving  company (or its parent company or other
controlling  entity) which at the time of such  transaction  would have a market
value of four times the exercise  price of the NSS Right.  In the event that NSS
were the surviving corporation in a merger with any person, the Rights Agreement
requires that proper provision be made so that each holder of a NSS Right, other
than the Acquiring  Person (whose Rights would  thereafter be null and void) and
certain of its  transferees,  would  thereafter  have the right to receive  upon
exercise that number of shares of NSS common stock having a market value of four
times  the  exercise  price of the NSS Right  (i.e.,  a 75%  discount  to market
value).  If insufficient  shares are available to satisfy the NSS Right, NSS may
substitute  other  consideration,  as appropriate,  or make an adjustment to the
exercise price of the NSS Right to achieve  substantially  the intended economic
benefit to shareholders (other than the Acquiring Person) of the 75% discount.

     In  approving  and  recommending  the  Reorganization,  the NSS  Board  has
formally  determined  that Summit shall not be deemed to be an Acquiring  Person
and that Rights  shall not be  exercisable  as a result of the  execution of the
Reorganization Agreement or Reorganization Option Agreement or effectuation
thereof.



                   PROPOSAL II-ADJOURNMENT OF SPECIAL MEETING

     In the event there are not  sufficient  votes to  constitute a quorum or to
approve the  Reorganization  Agreement at the time of the Special  Meeting,  the
Reorganization  Agreement  could not be approved unless the Special Meeting were
adjourned in order to permit further  solicitation of proxies. In order to allow
proxies that have been received by NSS at the time of the Special  Meeting to be
voted for such  adjournment,  if  necessary,  NSS has  submitted the question of
adjournment under the circumstances to its shareholders as a separate matter for
their consideration. In order to approve any such adjournment more votes must be
cast in favor  of  Proposal  II than  against.  The NSS  Board  recommends  that
shareholders  vote  their  proxies  in favor of such  adjournment  so that their
proxies may be used for such purposes in the event it should  become  necessary.
Properly executed proxies will be voted in favor of any such adjournment  unless
otherwise  indicated thereon. If it is necessary to adjourn the Special Meeting,
no notice of the time and place of the adjourned meeting is required to be given
to shareholders other than an announcement of such time and place at the Special
Meeting unless such adjournment exceeds 90 days.



                             SHAREHOLDER PROPOSALS


     In order to be eligible for  inclusion in NSS's proxy  materials  for NSS's
Annual  Meeting  of  Shareholders  in the event that the  Reorganization  is not
consummated  prior to such meeting,  any shareholder  proposal to take action at
such meeting  would have been required to be received at NSS's main office at 48
Wall Street,  Norwalk,  Connecticut  06852  within a reasonable  time before NSS
begins  to  print  its  proxy  materials.  NSS  will  provide  prior  notice  to
shareholders of an intent to hold an annual meeting. Any such proposals shall be
subject to the requirements of the proxy rules adopted under the Exchange Act.

     The Summit Board will  consider  and include in the Summit Proxy  Statement
for the 1999  Annual  Meeting of Summit  shareholders  proposals  which meet the
regulations  of the  Commission  and New Jersey law and which comply with Summit
By-Laws. In order to be considered for inclusion,  proposals must be received on
or before  November 6, 1998.  Proposals  should be addressed to the Secretary of
Summit.

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


                                       49


<PAGE>


or the tenth day following the day on which public  announcement  of the meeting
date is first made.  Any such notice of a shareholder  proposal by a shareholder
to the  Secretary of Summit must be  accompanied  by (a) the name and address of
the  shareholder  who  intends  to  present  the  proposal  for  a  vote,  (b) a
representation that such shareholder is a holder of record of shares entitled to
vote at the  meeting,  (c) a  description  of all  agreements,  arrangements  or
understandings  between such shareholder and any other  shareholder  relating to
the  proposal  to be voted on and any  financial  contractual  interest  of such
shareholder in the outcome of such vote and (d) such other information regarding
the  proposal  to be voted  on and the  shareholder  intending  to  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 such proposal  pursuant to the
proxy rules of the Commission. 



                                 LEGAL MATTERS


     The legality of the Summit  Common  offered  hereby will be passed upon for
Summit by Richard F. Ober, Jr., Esq., Executive Vice President,  General Counsel
and  Secretary  of Summit.  Mr.  Ober owns  43,473  shares of Summit  Common and

        become  entitled to receive  pursuant to this Section  1.03(a)(2)  shall
        equal the product  obtained by multiplying  the fraction,  if any, which
        results from the  foregoing  multiplication  by the closing price of one
        share of Summit Stock on the New York Stock  Exchange  (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 NSS and Summit) on the last  trading day ending  prior to
        the Effective  Time.  (The shares of Summit Stock issuable in accordance
        with this Section  1.03(a)(2)  are  sometimes  referred to herein as the

        Section 1.03(b) below, 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 NSS Stock  shall be  appropriately  adjusted  to give  effect to the Capital
Change.

     (c) The  Exchange  Ratio  is  hereby  defined  to be one  and  two  hundred
thirty-two thousandths (1.232),  adjusted as and if necessary in accordance with
Section 1.03(b).

     Section 1.04.  RESERVATION OF SUMMIT STOCK;  ISSUANCE OF SHARES PURSUANT TO

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

Section 1.07(c), prior to the time such obligations arise.

     Section 1.06. EFFECTIVE TIME.

     (a) The Reorganization  shall be effective at the time and date ("Effective

   (1)  if the  Reorganization  is a merger  pursuant to Sections  1.01(a)(1) or
        (2), the time and date specified in the  certificate or  certificates of
        merger required to be filed with the  jurisdiction or  jurisdictions  of
        incorporation  of each of the  constituent  corporations  to the merger,

        merger are required; and

   (2)  if the Reorganization is an exchange pursuant to Section 1.01(a)(3), the
        time and date specified in the  certificate  of exchange  required to be

Reorganization  Certificate  set forth,  as the case may be in  accordance  with
Summits  election  pursuant  to Section  1.01(a),  a plan of merger or a plan of
share exchange, or that one of such plans be attached thereto, then:

   (1)  If Summit  has  elected a method  for  carrying  out the  Reorganization
        provided for at Section 1.01(a)(1) or Section  1.01(a)(3),  Summit shall
        revise  the  title of this  Agreement  where it  appears  herein  to, as
        appropriate  in accordance  with the election made by Summit,  Agreement
        and Plan of Merger or  Agreement  and Plan of Share  Exchange  and shall
        attach  a copy of  this  Agreement  so  revised  to such  Reorganization
        Certificate in satisfaction of the relevant  corporate law  requirement;
        or

   (2)  If  Summit  has  elected  to carry  out the  Reorganization  by a merger
        provided  for at  Section  1.01(a)(2),  Summit  shall  attach  a plan of
        mergerto this Agreement as Exhibit A and such Exhibit A shall constitute
        a part of this  Agreement  as fully as if  attached  hereto  on the date
        hereof  and  Summit  shall  include  such  plan  in  the  Reorganization
        Certificate in satisfaction of the relevant  corporate law  requirement.
        Plan of merger for purposes of this Section  1.06(c)(2)  means a plan of
        merger  (i)  dated as of the  date  hereof,  (ii)  meeting  the  minimum
        requirements  of the  corporate  laws which  require a plan of merger as
        part of the Reorganization  Certificate,  and (iii) containing terms and
        conditions  consistent  in  all  material  respects  to  the  terms  and
        conditions  contained in this  Article I,  including  where  appropriate

        articles  of  incorporation  and  amendments   thereto  or  restatements
        thereof,  by-laws and amendments thereto,  and directors and officers of
        the corporation  surviving the merger;  provided,  however, that no such
        other term or condition  shall (x) alter or change the amount or kind of
        consideration  to be received by  Shareholders of NSS as provided for in
        this  Agreement,   (y)  adversely   affect  the  tax  treatment  of  the
        Reorganization Consideration (as defined in Section 1.03(a)(2) below) to

     Section 1.07. EXCHANGE OF NSS CERTIFICATES.

     (a) After the Effective Time and subject to Section 1.07(c) below, each NSS
Shareholder  (except as provided otherwise in Section  1.03(a)(1)  above),  upon
surrender to the Exchange  Agent of all NSS  Certificates  registered to the NSS
Shareholder,  shall  be  entitled  to  receive  in  exchange  therefor  a Summit
Certificate  representing  the number of whole  shares of Summit  Stock such NSS
Shareholder  becomes entitled to receive pursuant to Section  1.03(a)(2) and the
Cash In Lieu Amount,  payable by check, such NSS Shareholder may become entitled
to  receive  pursuant  to  Section  1.03(a)(2);  provided,  however,  that a NSS
Affiliate (as defined at Section 4.11) shall not become entitled to exchange NSS
Certificates for the  Reorganization  Consideration as described in this Section
1.07(a) until such time as Summit shall have received  from the  particular  NSS
Affiliate an executed Affiliate Agreement (as defined at Section 4.11). Until so
surrendered,  outstanding NSS Certificates  held by each NSS Shareholder,  other
than NSS certificates  governed by Section  1.03(a)(1),  shall be deemed for all
purposes  (other  than as  provided  below  with  respect to  unsurrendered  NSS
Certificates  and  Summit's  right  to  refuse  payment  of  dividends  or other
distributions,  if any, in respect of Summit Stock) to represent  only the right
to  receive  the  number of whole  shares  of Summit  Stock and the Cash In Lieu
Amount,  if any,  determined in  accordance  with Section  1.03(a)(2).  Until so
surrendered,  Summit  may,  at its  option,  refuse to pay to the holders of the
unsurrendered  NSS  Certificates  dividends or other  distributions,  if any, on
Summit Stock declared after the Effective Time; provided, however, that upon the
surrender  and  exchange  of NSS  Certificates  following  a  dividend  or other
distribution  on Summit Stock there shall be paid to such NSS  Shareholders  the
amount,  without interest,  of dividends and other distributions,  if any, which
became payable prior thereto but which were not paid.

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

     (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  NSS Stock as of the  Effective  Time (NSS  Shareholders)
(including the address and social security number of and the number of shares of
NSS Stock  held by each NSS  Shareholder)  from NSS  (Final  Shareholder  List),
Summit  shall  cause  the  Exchange  Agent  to  send  to  each  NSS  Shareholder
instructions  and transmittal  materials for use in surrendering  and exchanging
NSS Certificates for the Reorganization  Consideration.  If NSS 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 NSS cause the Exchange Agent to cancel and
exchange NSS 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 NSS, 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 NSS of the shares of NSS Stock which were  outstanding
immediately prior to the Effective Time.

     Section 1.08.  RESTATED  CERTIFICATE OF INCORPORATION  AND BY-LAWS.  In the
event the method of Reorganization set forth at Section 1.01(a)(1) is elected by
Summit:

     (a)  the  Restated   Certificate  of  Incorporation  of  Summit  in  effect
immediately  prior to the Effective  Time shall be the Restated  Certificate  of
Incorporation   of  the  surviving   corporation   in  such  merger   (Surviving
Corporation), except as duly amended thereafter and except to the extent such is
deemed by law to be affected by the Reorganization Certificate; and

     (b) the By-Laws of Summit in effect immediately prior to the Effective Time
shall be the  By-Laws  of the  Surviving  Corporation,  except  as duly  amended
thereafter.

     Section 1.09.  BOARD OF DIRECTORS AND OFFICERS.  In the event the method of
Reorganization set forth at Section 1.01(a)(1) is elected by Summit:


                                      A-4


<PAGE>


     (a) the Board of Directors of the  Surviving  Corporation  shall consist of
the  members of the Board of  Directors  of Summit at the  Effective  Time;  and
(b)the  officers of the Surviving  Corporation  shall consist of the officers of
Summit at the Effective  Time.  Such  directors and officers shall serve as such
for the terms  prescribed  in the  Restated  Certificate  of  Incorporation  and
By-Laws  of Summit,  or as  otherwise  provided  by law or until  their  earlier
deaths, resignation or removal.

     Section 1.10. NSS STOCK OPTIONS.

     (a) At the Effective  Time,  each NSS Option (as defined in Section 1.10(b)
below) shall be deemed to constitute,  and shall  automatically  be converted at
the Exchange Ratio into,  options to purchase Summit Stock  (Converted  Options)
and each  Converted  Option shall be  administered  in all material  respects in
accordance  with  the  terms  and  conditions  provided  for  in the  NSS  Stock
Compensation  Plan under  which the related NSS Option was granted and the stock
option agreement by which it was evidenced. The number of shares of Summit Stock
which may be purchased upon exercise of a particular  Converted  Option shall be
the number of shares of NSS Stock which would have been  issuable  upon exercise
in full of the related NSS 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 NSS Option divided by the Converted Number and rounded up
to the nearest ten-thousandth decimal place. In the event a Capital Change shall
occur prior to the Effective  Time, an appropriate  adjustment  shall be made to
the terms of the NSS  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 NSS
Options,  all  information  about  the  NSS  Options  and  the  holders  thereof
(including  the  address  and social  security  number of each such holder and a
description of the NSS 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 NSS Stock subject
thereto)  and  copies of each form of option  agreement,  warrant  agreement  or
letter  agreement  entered into between NSS and a holder of a NSS Option (all of
the  foregoing  being  collectively  referred  to as the Final  Option  List and
Materials),  Summit  shall issue to the holders of such NSS 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 NSS 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 30 days after NSS 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 the 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,  NSS 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, NSS Option is hereby defined to mean
an option  relating  to the  purchase of NSS Stock,  and any rights  appurtenant
thereto including Equity Based Rights (as defined at Section  2.01(d)(2) below),
granted under a NSS Stock  Compensation  Plan (as defined at Section  2.01(d)(3)
below), outstanding both on the date hereof and at the Effective Time.

     Section 1.11. ADDITIONAL ACTIONS. If, at any time after the Effective Time,
the  surviving  corporation  to any  of the  mergers  contemplated  by  Sections
1.01(a)(1)  or (2) shall  consider or be advised that any deeds,  bills of sale,
assignments,  assurances  or any  other  actions  or  things  are  necessary  or
desirable to vest,  perfect or confirm of record or otherwise in such  surviving
corporation  its right,  title or  interest  in, to or under any of the  rights,
properties or assets of the  nonsurviving  corporation or otherwise to carry out
this Agreement, the officers and directors of the surviving corporation shall be
authorized to execute and deliver, in the name and on


                                      A-5


<PAGE>


behalf of the nonsurviving  corporation or otherwise,  all such deeds,  bills of
sale,  assignments  and assurances and to take, in the name and on behalf of the
nonsurviving corporation,  all such other actions and things as may be necessary
or desirable to vest,  perfect or confirm any and all right,  title and interest
in, to and under such rights,  properties or assets in the surviving corporation
or otherwise to carry out this Agreement.

     Section  1.12.  UNCLAIMED  REORGANIZATION   CONSIDERATION.   If,  upon  the
expiration   of  one  year   following  the   Effective   Time,   Reorganization
Consideration  remains  with  the  Exchange  Agent  due  to the  failure  of NSS
Shareholders  to  surrender  and exchange NSS  Certificates  for  Reorganization
Consideration,  Summit may,  at its  election,  continue to retain the  Exchange
Agent for purposes of the  surrender  and exchange of NSS  Certificates  or take
possession of such unclaimed Reorganization Consideration,  in which such latter
case, NSS Shareholders who have theretofore failed to surrender and exchange NSS
Certificates   shall   thereafter  look  only  to  Summit  for  payment  of  the
Reorganization  Consideration  and the unpaid dividends and distributions on the
Summit Stock declared after the Effective  Time,  without any interest  thereon.
Notwithstanding  the foregoing,  none of Summit,  NSS, the Exchange Agent or any
other person shall be liable to any former holder of shares of NSS Stock for any
property  properly  delivered  to  a  public  official  pursuant  to  applicable
abandoned property, escheat or similar laws.

     Section 1.13. LOST NSS CERTIFICATES. In the event any NSS Certificate shall
have been lost,  stolen or  destroyed,  upon the making of an  affidavit of that
fact by the person claiming such NSS Certificate to be lost, stolen or destroyed
and the posting by such person of a bond in such amount as Summit may  determine
is reasonably  necessary as indemnity against any claim that may be made against
it with  respect  to such NSS  Certificate,  the  Exchange  Agent  will issue in
exchange for such lost,  stolen or destroyed NSS Certificate the  Reorganization
Consideration deliverable in respect thereof pursuant to this Agreement.

perform its obligations  under, and to consummate the transactions  contemplated

loan associations and similar institutions receiving deposits and making loans).
Bank is a bank duly organized,  validly existing, and in good standing under the
jurisdiction of its organization and is qualified to transact business under the
laws of all  jurisdictions  where the failure to be so qualified would be likely
to have a NSS Material  Adverse  Effect.  Bank is duly authorized to conduct all
activities and exercise all powers of a capital stock savings bank  contemplated
by the laws of  Connecticut.  Bank is an insured  bank as defined in the Federal
Deposit Insurance Act and has all corporate power and authority and all material
licenses,   franchises,    certificates,    permits   and   other   governmental
authorizations  which are legally  required to own and lease its  properties and
assets, to occupy its premises,  and to engage in its business and activities as
presently  engaged  in,  and has  complied  in all  material  respects  with all
applicable laws, regulations and orders.


     (f) The authorized and outstanding capital stock of Bank is as set forth on
NSS  Schedule  2.01(f).  NSS is the  holder and  beneficial  owner of all of the
issued and  outstanding  Equity  Securities of Bank. All issued and  outstanding
shares of the capital stock of Bank have been fully paid,  were duly  authorized
and validly issued, are non-assessable,  and were not issued in violation of the
preemptive rights of any shareholder. All Equity Securities of Bank outstanding,
in existence, the subject of an agreement or reserved for issuance are described
in all material respects on NSS Schedule 2.01(f).


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


     Section 2.02. FINANCIAL  STATEMENTS.  The financial statements (and related
notes and schedules thereto) contained in or incorporated by reference into NSSs
(a) annual report to  shareholders  for the fiscal year ended December 31, 1997,
(b) annual report on Form 10-K filed pursuant to the Securities  Exchange Act of
1934, as amended  (Exchange Act) for the fiscal year ended December 31, 1997 and
(c) the quarterly report on Form 10-Q filed pursuant to the Exchange Act for the
fiscal  quarter ended March 31, 1998 (the "NSS 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  NSS  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 NSS  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 NSS
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 NSS Schedule  2.03, NSS
and each of its  subsidiaries is not in violation or breach of or default under,
and has received no notice of  violation,  breach,  revocation  or threatened or
contemplated  revocation of or default or denial of approval under, nor will the
execution,   delivery  and   performance  of  this  Agreement  by  NSS,  or  the
consummation   of   the   transactions   contemplated   hereby   including   the
Reorganization  by NSS 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 NSS or any of
its  subsidiaries  or upon  any of the  Equity  Securities  of NSS or any of its
subsidiaries, or constitute an event which could, with the lapse of time, action
or inaction by NSS 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 of Incorporation or the  By-Laws of  NSS 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


                                      A-8


<PAGE>


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

     to which NSS or any of its  subsidiaries  is a party or by which NSS or any
of its subsidiaries or any of their assets or properties are bound or committed,
the  consequences  of which  individually or in the aggregate would be likely to
result in a material  adverse  change in the  business,  results of  operations,
assets or financial  condition of NSS and its  subsidiaries,  on a  consolidated
basis,  from that  reflected in the NSS  Financial  Statements as of and for the
three months ended March 31, 1998 (NSS Material Adverse  Change),  or enable any
person to enjoin the transactions contemplated hereby.

     Section 2.04. ABSENCE OF UNDISCLOSED LIABILITIES.  NSS 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 NSS 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 NSS Financial
Statements or disclosed in the notes thereto, (b) commitments made by NSS or any
of its  subsidiaries in the ordinary course of its business which are not in the
aggregate material to NSS and its subsidiaries, on a consolidated basis, and (c)
liabilities arising in the ordinary course of its business since March 31, 1998,
which  are not in the  aggregate  material  to NSS and  its  subsidiaries,  on a
consolidated basis. Other than as may be set forth on NSS Schedule 2.04, neither
NSS nor any of its subsidiaries  has, since March 31, 1998,  become obligated on
any debt due in more than one year from the date of this  Agreement in excess of
$100,000,  other than  intra-corporate  debt and deposits  received,  repurchase
agreements and borrowings from the Federal Home Loan Bank of 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 NSS or any of its subsidiaries  which
materially  and adversely  affects NSS and its  subsidiaries,  on a consolidated
basis,  and  there  are  no  actions,  arbitrations,   claims,  charges,  suits,
investigations  or  proceedings  (formal or  informal)  material  to NSS and its
subsidiaries,   on  a  consolidated  basis,   pending  or,  to  NSSs  knowledge,
threatened,  against  or  involving  NSS 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 NSS  referred  to in Section  2.02.  Neither  Bank nor NSS is a
party to any agreement or memorandum of understanding with, or is a party to any
commitment  letter  to, or has  submitted  a board of  directors  resolution  or
similar  undertaking  to, or is  subject to any order or  directive  by, or is a
recipient of any  extraordinary  supervisory  letter from, any  governmental  or
regulatory authority which restricts materially the conduct of its business,  or
in  any  manner  relates  to  material  statutory  or  regulatory  noncompliance
discovered in any regulatory  examinations,  its capital adequacy, its credit or
reserve policies or its management. Neither Bank nor NSS has been advised by any
governmental  or  regulatory  authority  that  it is  contemplating  issuing  or
requesting (or is considering the  appropriateness of issuing or requesting) any
of the foregoing. Neither Bank nor NSS 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 Banks
and of  NSSs  business  nor has  Bank or NSS  been  advised  of any  significant
deficiencies  by any such agency in connection  with any current  examination of
Bank or of NSS by any such agency.

     Section  2.06.  BROKERS'  FEES.  NSS 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 Sandler
O'Neill & Partners,  L.P. (Sandler O'Neill).  NSS Schedule 2.06 consists of true
and  complete  copies of all  agreements  between NSS and Sandler  O'Neill  with
respect  to  the   transactions   contemplated  by  this  Agreement  or  similar
transactions.

     Section 2.07.  REGULATORY  FILINGS. At the time of filing, all filings made
by NSS and  its  subsidiaries  after  December  31,  1992  with  the SEC and the
appropriate  bank  regulatory  authorities  do not or did not contain any untrue
statement  of a material  fact and do not or did not omit to state any  material
fact required to be stated herein or therein or necessary to make the statements
contained therein, in light of the circumstances under which they were made, not
misleading.  To the extent such filings were  subject to the  Securities  Act or
Exchange Act, such filings complied in all material respects with the Securities
Act or Exchange Act, as appropriate, and


                                      A-9


<PAGE>


all  applicable  rules  and  regulations  thereunder  of the  SEC.  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  NSS  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.  NSS and
its subsidiaries  have since December 31, 1992, 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 NSS of this
Agreement, the Reorganization and the other transactions  contemplated hereby in
accordance with NSSs Certificate of  Incorporation  and the Connecticut Act at a
meeting of such holders to be duly called and held, NSS 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 NSS has taken all  action
required by law, its Certificate of Incorporation  (including  specific approval
of the Reorganization  pursuant to Article SIXTH,  Paragraph C.(1) thereof), its
By-Laws or otherwise,  including the NSS Rights Agreement,  (i) to authorize the
execution  and delivery of this  Agreement  and (ii)  provided  Summit  elects a
method for carrying out the  Reorganization  set forth at Section  1.01(a)(1) or
Section  1.01(a)(2) of this Agreement,  for  shareholders of NSS to approve this
Agreement and the transactions  contemplated hereby including the Reorganization
by a simple  majority  of the  votes  entitled  to be cast on the  matter at the
meeting  held in  accordance  with Section  4.03.  Assuming  due  execution  and
delivery  by Summit,  this  Agreement  is a valid and binding  agreement  of NSS
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 NSS in authorizing the execution of this
Agreement has determined to recommend to the shareholders of NSS the approval of
this  Agreement,  the  Reorganization  and the other  transactions  contemplated
hereby  and such other  proposals  as may be  requested  by Summit  pursuant  to
Section 4.03.


     Section 2.09. ABSENCE OF CHANGES. There has not been, since March 31, 1998,
any NSS Material Adverse Change except as may be set forth in NSS Schedule 2.09.
Except  as may be set forth in NSS  Schedule  2.09,  neither  NSS nor any of its

     Section 2.10. ALLOWANCE FOR CREDIT LOSSES. At March 31, 1998 and thereafter
the  allowances  for  credit  losses  of NSS 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 NSSs knowledge, the loan and lease portfolios of
NSS in excess of such  allowances  are  collectible  in the  ordinary  course of
business.  NSS Schedule 2.10  constitutes a list of all loans and leases made by
NSS 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  NSS  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 NSS 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 NSS and each of its  subsidiaries
for all periods in compliance with the tax, social  security,  unemployment  and
other applicable  withholding  provisions of applicable federal, state and local
law.  Proper and accurate  federal,  state and local returns (as defined  below)
have been timely filed by NSS and each of its  subsidiaries  for all periods for
which  returns  were  due,   including  with  respect  to  employee  income  tax
withholding,  social  security,  unemployment  and  other  applicable  taxes (as
defined below), and the amounts shown thereon to be due and payable,  as well as
any interest, additions, and penalties due with respect to completed and settled
examinations or concluded litigation relating to NSS or any of its subsidiaries,
have been paid in full or adequate  provision  therefor has been included on the
books  of  NSS  or  its  appropriate  subsidiary.  Neither  NSS  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 NSS or its appropriate
subsidiary  for all unpaid taxes,  whether or not disputed,  that may become due
and payable by NSS or any of its  subsidiaries  in future  periods in respect of
transactions, sales or services occurring or performed prior to the date of this
Agreement.  The Internal  Revenue Service  ("IRS") has audited the  consolidated
federal  income tax  returns of NSS for all  taxable  years ended on or prior to
1990 and the State of Connecticut  has not, since 1992,  audited the Connecticut
income  tax  returns  of NSS and its  subsidiaries.  Neither  NSS 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. NSS 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 NSS nor any of its  subsidiaries is currently a party to any tax sharing
or  similar  agreement  with any third  party.  There are no  material  matters,
claims,  assessments,  examinations,  notices of deficiency,  demands for taxes,
refund litigation,  proceedings,  audits or proposed deficiencies pending or, to
NSSs knowledge,  threatened against NSS or any of its subsidiaries,  including a
claim or assessment by any authority in a  jurisdiction  where NSS or any of its
subsidiaries  do not file tax returns and NSS 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  NSS 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 NSS or any of its  subsidiaries,
and neither NSS nor any of its  subsidiaries  has any knowledge that the IRS has
proposed  any such  adjustment  or  change  in  accounting  method.  NSS 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,


                                      A-11

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.  NSS 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 NSS Financial  Statements  (except
individual  properties  and  assets  disposed  of since  March  31,  1998 in the
ordinary course of business), which properties and assets are not subject to any
mortgage, pledge, lien, charge or encumbrance other than as reflected in the NSS
Financial  Statements  or which in the  aggregate  do not  materially  adversely
affect or impair the operation of NSS and its  subsidiaries,  on a  consolidated
basis.  NSS  and  each  of its  subsidiaries  enjoys  peaceful  and  undisturbed
possession  under all material leases under which it or any of its  subsidiaries
is the  lessee,  where  the  failure  to enjoy  such  peaceful  and  undisturbed
possession  would be likely to have a NSS 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 NSS and its
subsidiaries, on a consolidated basis.

     Section 2.13.  CONDITION OF  PROPERTIES;  INSURANCE.  All real and tangible
personal  properties  owned by NSS or any of its  subsidiaries or used by NSS or
any of its  subsidiaries  in its business are in a good state of maintenance and
repair,  are in good  operating  condition,  subject  to  normal  wear and tear,
conform in all material respects to all applicable  ordinances,  regulations and
zoning  laws,  and  are  adequate  for  the  business  conducted  by NSS or such
subsidiary  subject to exceptions  which are not, in the aggregate,  material to
NSS  and  its  subsidiaries,  on a  consolidated  basis.  NSS  and  each  of its
subsidiaries  maintains  insurance  (with  companies  which, to the best of NSSs
knowledge,  are approved by all appropriate  state insurance  regulators to sell
such insurance  where purchased by NSS) 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  in an amount and form and are  otherwise  adequate  to
protect NSS and each of its  subsidiaries  from any adverse loss  resulting from
risks  and  liabilities  reasonably  foreseeable  at the  date  hereof,  and are
disclosed on NSS Schedule 2.13. All material  claims  thereunder have been filed
in a due and timely fashion. Since December 31, 1992, neither NSS nor any of its
subsidiaries  has been  refused  insurance  for which it has  applied or had any
policy of insurance  terminated  (other than at its request) nor have NSS or any
of its  subsidiaries  received  notice from any insurance  carrier that (i) such
insurance  will be  canceled  or that  coverage  thereunder  will be  reduced or
eliminated  or  (ii)  premium  costs  with  respect  to such  insurance  will be
increased.

     Section 2.14. CONTRACTS.

     (a) Except as set forth in NSS Schedule 2.14(a), neither NSS nor any of its
subsidiaries is a party to and neither they nor any of their assets are bound by
any  written or oral  lease or license  with  respect to any  property,  real or
personal,  as tenant or licensee involving an annual  consideration in excess of
$50,000.

     (b) Except as set forth in NSS Schedule  2.09 or in NSS  Schedule  2.14(b),
neither NSS 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 NSS bargaining contract or union
agreement) or other agreement with any director,  executive officer or other key
employee of NSS or any subsidiary,  the benefits of which are contingent, or the
terms of which are  materially  altered,  upon the  occurrence  of a transaction
involving  NSS or any of its  subsidiaries  of the nature  contemplated  by this
Agreement  which is not terminable  without  penalty by NSS 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 supplies or for the  performance of services  involving
consideration  in  excess  of  $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,


                                      A-12


<PAGE>


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

     (c)  Neither  NSS nor any of its  subsidiaries  is a party to or  otherwise
bound  by  any  contract,   agreement,  plan,  lease,  license,   commitment  or
undertaking which, in the reasonable opinion of management of NSS, is materially
adverse,  onerous,  or  harmful  to any  aspect of the  business  of NSS and its
subsidiaries, on a consolidated basis.

     Section 2.15. PENSION AND BENEFIT PLANS.

     (a) Neither NSS nor any of its  subsidiaries  maintains an employee pension
benefit  plan,  within the meaning of Section  3(2) of the  Employee  Retirement
Income Security Act of 1974, as amended ("ERISA"), or has made any contributions
to any such employee pension benefit plan, except employee pension benefit plans
listed  in  NSS  Schedule  2.15(a)   (individually  a  "NSS  Pension  Plan"  and
collectively the "NSS Pension Plans"). In its present form each NSS Pension Plan
complies in all material respects with all applicable  requirements  under ERISA
and the  Code.  Each  NSS  Pension  Plan and the  trust  created  thereunder  is
qualified and exempt under  Sections  401(a) and 501(a) of the Code,  and NSS or
the subsidiary whose employees are covered by such NSS Pension Plan has received
from the IRS a determination letter to that effect and such determination letter
may still be relied on. No event has  occurred and there has been no omission or
failure to act which would  adversely  affect such  qualification  or exemption.
Each NSS Pension Plan has been administered and communicated to the participants
and  beneficiaries  in all material  respects in  accordance  with its terms and
ERISA. No employee or agent of NSS or any subsidiary whose employees are covered
by a NSS 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 NSS Pension
Plans  qualification and the associated trusts exemption or impose any liability
or  penalty  under  the  Code,  or  (ii)  a  participant  or  beneficiary  or  a
nonparticipating employee has been denied benefits properly due or to become due
under such NSS  Pension  Plan or has been  misled as to his or her rights  under
such NSS Pension Plan. No NSS Pension Plan is subject to Section 412 of the Code
or Title IV of ERISA.  No  person  has  engaged  in any  prohibited  transaction
involving any NSS Pension Plan or associated trust within the meaning of Section
406 of ERISA or Section  4975 of the Code.  There are no  pending or  threatened
claims (other than routine claims for benefits) against the NSS Pension Plans or
any fiduciary  thereof which would subject NSS or any of its  subsidiaries  to a
material  liability.  All reports,  filings,  returns and  disclosures and other
communications  which  have been  required  to be made to the  participants  and
beneficiaries, other employees, the Pension Benefit Guaranty Corporation (PBGC),
the SEC, the IRS, the U.S.  Department of Labor or any other governmental agency
pursuant to the Code, ERISA, or other applicable statute or regulation have been
made in a timely manner and all such reports,  communications,  filings, returns
and disclosures were true and correct in all material respects. No liability has
been,  or is likely to be,  incurred  on account  of  delinquent  or  incomplete
compliance or failure to comply with such  requirements.  ERISA  Affiliate where
used in this Agreement means any trade or business (whether or not incorporated)
which is a member of a group of which NSS is a member and which is under  common
control  within the meaning of Section  414 of the Code.  Neither NSS nor any of
its subsidiaries has any material  liability under ERISA or the Code as a result
of its being a member of a group described in Sections  414(b),  (c), (m) or (o)
of the Code. There are no unfunded benefit or pension plans or arrangements,  or
any individual  agreements  whether qualified or not, to which NSS or any of its
subsidiaries or ERISA Affiliates has any obligation


                                      A-13


<PAGE>


to  contribute  and the present  value of all  benefits  vested and all benefits
accrued  under each NSS  Pension  Plan which is subject to Title IV of ERISA did
not, in each case, as of the last applicable  annual valuation date,  exceed the
value of the assets of the NSS Pension Plan  allocable to such vested or accrued
benefits.  No NSS  Pension  Plan  or  any  trust  created  thereunder  has  been
terminated,  nor has there been any  reportable  events with  respect to any NSS
Pension  Plan, as that term is defined in Section 4043 of ERISA since January 1,
1990.  No NSS Pension  Plan or any trust  created  thereunder  has  incurred any
accumulated  funding  deficiency as such term is defined in Section 302 of ERISA
(whether or not  waived).  No NSS 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 NSS 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  NSS  Stock  Compensation  Plans  and  medical,  major  medical,
disability,  life insurance or dental plans covering employees generally,  other
than the NSS Pension Plans, maintained by NSS or any of its subsidiaries with an
annual cost in excess of $50,000  (collectively  "NSS Benefit Plans") are listed
in NSS Schedule  2.15(b) (unless  already listed in NSS Schedule  2.15(a) or NSS
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 NSS Benefit Plans have
been  administered and communicated to the participants and beneficiaries in all
material respects in accordance with their terms and ERISA (as applicable),  and
no employee or agent of NSS or any of its subsidiaries has engaged in any action
or failed to act in such manner that, as a result of such action or failure: (i)
the IRS could revoke, or refuse to issue, a favorable  determination as to a NSS
Benefit Plans  qualification  and any associated  trusts exemption or impose any
liability or penalty under the Code; or (ii) a participant  or  beneficiary or a
nonparticipating employee has been denied benefits properly due or to become due
under the NSS Benefit  Plans or has been misled as to their rights under the NSS
Benefit  Plans.  There are no pending or  threatened  claims (other than routine
claims for  benefits)  against the NSS Benefit  Plans which would subject NSS or
any of its  subsidiaries  to  liability.  Any  trust  which  is  intended  to be
tax-exempt has received a  determination  letter from the IRS to that effect and
no event has occurred which would adversely affect such exemption.  All reports,
filings,  returns and disclosures  required to be made to the  participants  and
beneficiaries,  other employees of NSS or any of its subsidiaries, the PBGC, the
SEC, the IRS, the U.S.  Department  of Labor and any other  governmental  agency
pursuant to the Code, ERISA, or other applicable statute or regulation,  if any,
have been made in a timely  manner and all such  reports,  filings,  returns and
disclosures  were  true  and  correct  in all  material  respects.  No  material
liability  has been,  or is likely to be,  incurred on account of  delinquent or
incomplete compliance or failure to comply with such requirements.

     (c) There is no  pending  or,  to NSSs  knowledge,  threatened  litigation,
administrative  action or  proceeding  relating to any NSS  Benefit  Plan or NSS
Pension  Plan.  There  has  been no  announcement  or  commitment  by NSS or any
subsidiary of NSS to create an additional  NSS Benefit Plan or NSS Pension Plan,
or to amend a NSS  Benefit  Plan or NSS  Pension  Plan,  except  for  amendments
required by applicable  law, which may materially  increase the cost of such NSS
Benefit  Plan or NSS  Pension  Plan  and,  except  for any  plans or  amendments
expressly  described on NSS  Schedule  2.01(d)(3),  NSS Schedule  2.15(a) or NSS
Schedule  2.15(b),  NSS and its  subsidiaries  do not have any  obligations  for
post-retirement  or   post-employment   benefits  under  any  NSS  Benefit  Plan
(exclusive of any coverage mandated by the Consolidated  Omnibus  Reconciliation
Act of 1986  (COBRA) that cannot be amended or  terminated  upon more than sixty
(60) days notice without  incurring any liability  thereunder.  Disclosed on and
appended to NSS  Schedule  2.15(c) with respect to each NSS Benefit Plan and NSS
Pension Plan, to the extent applicable,  is (A) the most recent annual report on
the  applicable  form of the Form 5500  series  filed  with the IRS with all the
attachments filed, (B) such NSS Benefit Plan or NSS Pension Plan,  including all
amendments thereto,  (C) each trust agreement and insurance contract relating to
such plan,  including  amendments  thereto,  (D) the most  recent  summary  plan
description for such plan,  including amendments thereto, if the plan is subject
to Title I of ERISA,  (E) the most recent  actuarial report or valuation if such
plan is a pension plan and (F) the most recent  determination  letter  issued by
the IRS if such plan is qualified under Section 401(a) of the Code.

     Section 2.16.  FIDELITY BONDS. Since December 31, 1992, NSS and each of its
subsidiaries  has continuously  maintained  fidelity bonds insuring them against
acts of dishonesty in such amounts as are customary, usual


                                      A-14


<PAGE>


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,  a
deductible  amount  of not more than  $50,000)  and  neither  NSS 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 NSS 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 NSSs and its subsidiaries' past claim experience.

     Section 2.17. LABOR MATTERS.  Hours worked by and payment made to employees
of NSS 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 NSS 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 NSS
or its  appropriate  subsidiary.  NSS 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  NSS   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  NSSs  knowledge  threatened  with  respect  to  NSS  or  any  of  its
subsidiaries.  Since  December  31,  1992,  no  employee  of  NSS  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 NSS 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 NSS pending with, or, to the
knowledge of NSS, threatened by, any labor organization or group of employees of
NSS.

     Section  2.18.  BOOKS AND RECORDS.  The minute books of NSS and each of its
subsidiaries  contain  complete and accurate  records of and fairly  reflect all
actions taken at all meetings and accurately  reflect all other corporate action
of the shareholders and the boards of directors and each committee thereof.  The
books and  records of NSS and each of its  subsidiaries  fairly  and  accurately
reflect the  transactions  to which NSS 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 NSS or any subsidiary of NSS an aggregate  amount equal
to more than 5% of the shareholders equity of NSS or such subsidiary  (including
deposits,  other debts and contingent  liabilities) or (b) owes to NSS or any of
its  subsidiaries an aggregate  amount equal to more than 5% of the shareholders
equity of NSS 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  NSS  nor  any of its
subsidiaries has received notice or otherwise knows that the manner in which NSS
or any of its  subsidiaries  conducts its business  including its current use of
any material trademark,  trade name, service mark or copyright violates asserted
rights of others in any trademark,  trade name, service mark, copyright or other
proprietary right.

     Section 2.21.  EQUITY  INTERESTS.  Neither NSS nor any of its  subsidiaries
owns,  directly or indirectly,  except for the equity  interests of NSS in Bank,
the equity interests disclosed on NSS Schedule 2.01(a), and the equity interests
disclosed on NSS Schedule 2.21, any equity  interest,  other than by virtue of a
security interest securing an obligation not presently in default,  in any bank,
corporation,  partnership or other entity,  except: (a) in a fiduciary capacity;
or (b) an interest  valued at less than $25,000  acquired in  connection  with a
debt  previously   contracted.   None  of  the  investments   reflected  in  the
consolidated  balance  sheet  of NSS as of  March  31,  1998,  and  none of such
investments  made by it or any of its  subsidiaries  since  March 31,  1998,  is
subject to any  restriction  (contractual  or statutory),  other than applicable
securities laws, that would materially  impair the ability of the entity holding
such investment  freely to dispose of such investment at any time, except to the
extent any such  investments  are  pledged in the  ordinary  course of  business
(including  in  connection  with  hedging  arrangements  or  programs or reverse
repurchase  arrangements)  consistent  with prudent  banking  practice to secure
obligations of NSS or any of its subsidiaries.

        such Loan  Property,  any  violation  of  environmental  law which could
        materially adversely affect the value of such Loan Property to an extent
        which  could  prevent  or  delay  NSS or any  of its  subsidiaries  from
        recovering  the full value of its loan in the event of a foreclosure  on
        such Loan Property.


     (b)  Neither  NSS nor any  subsidiary  (i) is aware  of any  investigations

     Section 2.23. ACCOUNTING,  TAX AND REGULATORY MATTERS.  Neither NSS 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 contemplated
hereby from qualifying as a reorganization  within the meaning of Section 368 of
the Code, or (ii) materially impede or delay receipt of any approval referred to
in Section 4.01 or the  consummation  of the  transactions  contemplated by this
Agreement.


     Section 2.24. INTEREST OF MANAGEMENT AND AFFILIATES.

<PAGE>


families,  have been made in the  ordinary  course of  business  and on the same
terms and interest rates as those  prevailing for comparable  transactions  with
others and do not  involve  more than the normal  risk of  repayment  or present
other unfavorable features.

     (b) Except as set forth and  described in NSS Schedule  2.24, no present or
former officer or director of NSS or any of its  subsidiaries  or any Associated
Person (as defined in Section 2.24(d) below):

   (1)  has  any  interest  in any  property,  real  or  personal,  tangible  or

        subsidiaries except for the normal rights of a shareholder;

   (2)  has  an  agreement,  understanding,   contract,  commitment  or  pending

                    REPRESENTATIONS AND WARRANTIES OF SUMMIT

     Summit represents and warrants to NSS 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 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
177,667,801  shares  were  issued  and  outstanding  as of  April  30,  1998 and
6,000,000 shares of Preferred Stock,  each without par value, of which no shares
were issued and  outstanding  and 1,500,000  shares of Series R Preferred  Stock
were 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 would
have a material  adverse  effect on (i) the  business,  results  of  operations,
assets or financial condition of Summit and its subsidiaries,  on a consolidated
basis,  or (ii) the ability of Summit to perform its obligations  under,  and to
consummate the transactions  contemplated by, this Agreement (a "Summit Material
Adverse  Effect).  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. 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


                                      A-18


<PAGE>


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 and 1993 Incentive
Stock and Option  Plan and Series R  Preferred  Stock  issuable  pursuant to the
Rights Agreement.

     (d) Except as disclosed on Summit  Schedule 3.01, all Equity  Securities of
its  direct  and  indirect  subsidiaries  beneficially  owned  by  Summit  or  a
subsidiary of Summit are held free and clear of any claims, liens,  encumbrances
or security interests.

     Section 3.02. FINANCIAL  STATEMENTS.  The financial statements (and related
notes and schedules  thereto)  contained in or  incorporated  by reference  into
Summit's (a) annual report to  shareholders  for the fiscal year ended  December
31, 1997,  (b) annual  report on Form 10-K  pursuant to the Exchange Act for the
fiscal year ended  December 31, 1997 and (c) the  quarterly  report on Form 10-Q
filed  pursuant to the Exchange Act for the fiscal  quarter ended March 31, 1998
(the  "Summit  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
consistently  applied,  the consolidated  balance sheets,  statements of income,
statements of  shareholders'  equity and  statements of cash flows of Summit and
its  subsidiaries at its respective date and for the period to which it relates,
except as may  otherwise  be described  therein 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 three months ended March 31, 1998
(a Summit  Material  Adverse  Change),  or  enable  any  person  to  enjoin  the
transactions contemplated hereby.

     Section 3.04. ABSENCE OF LITIGATION, AGREEMENTS WITH BANK REGULATORS. There
is no outstanding order,  injunction,  or decree of any court or governmental or
self-regulatory body against or affecting Summit or its


                                      A-19


<PAGE>


subsidiaries which materially and adversely affects Summit and its subsidiaries,
on a  consolidated  basis,  and  there  are no  actions,  arbitrations,  claims,
charges,  suits,  investigations or proceedings (formal or informal) material to
Summit and its subsidiaries,  on a consolidated  basis,  pending or, to Summit's
knowledge,  threatened,  against  or  involving  Summit  or  their  officers  or
directors  (in their  capacity  as such) in law or equity or before  any  court,
panel or governmental  agency,  except as may be disclosed in the Forms 10-K and
10-Q of  Summit  referred  to in  Section  3.02.  Neither  Summit  nor any  bank
subsidiary of Summit is a party to any agreement or memorandum of  understanding
with,  or is a party to any  commitment  letter to, or has  submitted a board of
directors  resolution or similar  undertaking  to, or is subject to any order or
directive by, or is a recipient of any  extraordinary  supervisory  letter from,
any governmental or regulatory  authority which restricts materially the conduct
of its business, or in any manner relates to its capital adequacy, its credit or
reserve  policies or its  management.  Neither Summit nor any bank subsidiary of
Summit, has been advised by any governmental or regulatory  authority that it is
contemplating  issuing or requesting (or is considering the  appropriateness  of
issuing or requesting) any of the foregoing. Summit and the bank subsidiaries of
Summit have resolved to the satisfaction of the applicable regulatory agency any
significant   deficiencies   cited  by  any  such  agency  in  its  most  recent
examinations of each aspect of Summit or such bank subsidiary's  business except
for examinations, if any, received within the 30 days prior to the date hereof.

     Section 3.05.  REGULATORY  FILINGS. At the time of filing, all filings made
by  Summit  and its  subsidiaries  after  December  31,  1992  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,  1992  timely  made all
filings required by the Securities Act and the Exchange Act.

     Section 3.06. CORPORATE ACTION.

     (a) Assuming due  execution  and delivery by NSS,  Summit 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 Summit has taken
all action required by law or by the Restated  Certificate of  Incorporation  or
By-Laws of Summit or otherwise to authorize  the  execution and delivery of this

Reorganization  or the  transactions  contemplated  by  this  Agreement  are not
required by  applicable  law.  Assuming due  execution and delivery by NSS, 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  Summit  elects to effect the  Reorganization  as a merger
pursuant  to  Section  1.01(a)(2),  upon  the due  and  valid  approval  of this
Agreement by the Board of Directors  and sole  shareholder  of SummitSub and its
execution and delivery, assuming due execution and delivery by each of the other
parties  hereto,  this  Agreement  will  be a valid  and  binding  agreement  of
SummitSub  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 March 31, 1998,
any Summit Material Adverse Change.

     Section 3.08. NON-BANK  SUBSIDIARIES.  The non-bank  subsidiaries of Summit
did not,  taken in the  aggregate,  constitute  a  "significant  subsidiary"  of
Summit, as that term is defined in Rule 1-02(v) of Regulation S-X of the SEC (17
CFR '210.1-02(v)), at March 31, 1998.

     Section 3.09 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


                                      A-20


<PAGE>


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 March 31, 1998 which are
not in the aggregate material to Summit and its subsidiaries,  on a consolidated
basis.

     Section 3.10.  ALLOWANCE  FOR LOAN AND LEASE LOSSES.  At March 31, 1998 and
thereafter,  the  allowances  for  loan  and  lease  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.



                                  ARTICLE IV.

                               COVENANTS OF NSS

     NSS hereby covenants and agrees with Summit that:

REQUIRED  CONSENTS.  NSS 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 NSS to solicit  shareholders of NSS for
approval of the Reorganization.  In connection  therewith,  NSS will furnish all
financial or other information, including using best efforts to obtain customary
consents,  certificates,  opinions of counsel and other  items  concerning  NSS,
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).  NSS 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 NSS and its counsel a reasonable  opportunity
to  comment  on such  filings  and  regulatory  applications  and will  give due
consideration  to any  comments  of NSS and its counsel  before  making any such
filing or  application,  and Summit will provide NSS 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. NSS covenants and
agrees that all information  furnished by NSS for inclusion in the  Registration
Statement,  the  Proxy-Prospectus,  all  applications to appropriate  regulatory
agencies for approval of the  Reorganization,  and all information  furnished by
NSS to  Summit  pursuant  to this  Agreement  or in  connection  with  obtaining
Required  Consents,  will comply in all material respects with the provisions of
applicable law,  including the Securities Act and the Exchange Act and the rules
and regulations of the SEC thereunder, and will not contain any untrue statement
of a material  fact and will not omit to state any material  fact required to be
stated therein or necessary to make the statements  contained therein,  in light
of the  circumstances  under  which they were  made,  not  misleading.  NSS will
furnish to Sandler  O'Neill such  information as Sandler  O'Neill may reasonably
request for purposes of the opinion referred to in Section 8.07.

     Section 4.02. NOTICE OF ADVERSE CHANGES. NSS 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 NSS  contained  in this
Agreement  or the NSS  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 NSS Material  Adverse  Change,  (c) any inability or perceived
inability  of NSS 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 NSS or any of its subsidiaries or assets,
which, if determined  adversely to NSS or any of its subsidiaries,  would have a
NSS Material Adverse Effect or an


                                      A-21


<PAGE>


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 NSS or a subsidiary subsequent
to the date  hereof  and  prior to the  Effective  Time,  under  any  agreement,
indenture or  instrument  to which NSS or a subsidiary  is a party or is subject
and which is material to the  business,  operation  or condition  (financial  or
otherwise) of NSS 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.  NSS
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.  NSS will call a meeting  of NSS
shareholders for the purpose of voting upon this Agreement,  the  Reorganization
and the other transactions  contemplated hereby and such other proposals related
to NSSs Certificate of Incorporation and By-Laws and the NSS Rights Agreement as
Summit upon the advice of counsel shall  request to  effectuate  the purposes of
this Agreement and the Option  Agreement,  including a proposal to approve under
Article  THIRTEENTH of NSSs Certificate of Incorporation  the acquisition of NSS
Stock  contemplated by the Option Agreement and a proposal to annul or void such
Article  THIRTEENTH  with respect to the Option  Agreement and the  transactions
contemplated  thereby.  The  meeting of NSS  shareholders  contemplated  by this
Section  4.03  will  be held as  promptly  as  practicable  and,  in  connection
therewith,  will comply with the  Connecticut  Act and the  Exchange Act and all
regulations  promulgated  thereunder  governing  shareholder  meetings and proxy
solicitations.   In   connection   with  such   meeting,   NSS  shall  mail  the
Proxy-Prospectus  to NSS  shareholders and use, unless in the written opinion of
counsel such action would be a breach of their fiduciary duties by the directors
under  applicable law, its best efforts to obtain  shareholder  approval of this
Agreement, the Reorganization and the other transactions contemplated hereby and
any other proposals requested by Summit pursuant to this Section 4.03.

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

     Section 4.05. NO MATERIAL TRANSACTIONS. Until the Effective Time, NSS will

consent of Summit:

dividends,  other  than  dividends  from  subsidiaries  of NSS  to NSS or  other
subsidiaries of NSS except that NSS may declare, set aside and pay a dividend of
$0.13 per quarter; provided,  however, if Summit declares a dividend between the
date hereof and the  Effective  Time which  represents an increase over the last
dividend declared by Summit prior to the date hereof,  NSS may after the date of
such  declaration  declare,  set aside and pay a dividend  of $0.13 per  quarter
increased  by a  percentage  equal  to the  percentage  increase  in the  Summit
dividend.

     (b) declare or distribute any stock dividend or authorize or effect a stock
split;

     (c) merge with,  consolidate  with, or sell any material asset to any other

required  by changes  in laws,  regulations  or  generally  accepted  accounting
principles or changes that are to a preferable  accounting  method, and approved
in writing by NSSs independent certified public accountants.

     Section  4.07.  FURTHER  ACTIONS.  NSS will:  (a) execute and deliver  such
instruments  and take such other  actions as Summit  may  reasonably  require to

     Section 4.10. APPLICABLE LAWS. NSS and its subsidiaries will use their best
efforts to comply promptly with all requirements  which federal or state law may

to Summit,  not later than 10 business  days prior to the date of mailing of the

                                      A-24


<PAGE>

Affiliate   Agreement  to  Summit,   Summit  may  refuse  to  exchange  for  the
Reorganization Consideration the NSS Certificates held by such Affiliate.

     Section  4.12.  LOANS AND  LEASES  TO  AFFILIATES.  All  loans  and  leases
hereafter made by NSS or any of its subsidiaries to any of its present or former

or its representatives  pursuant hereto shall be treated as the sole property of
Summit and, if the Reorganization  shall not occur, NSS and its  representatives

continuing  obligation  of  confidentiality.  NSS shall,  and shall use its best
efforts to cause its representatives to, keep confidential all 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 NSSs  possession  prior to the disclosure  thereof by Summit,

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

initiate, solicit or encourage, directly or indirectly, any inquiries, proposals
or offers with respect to, or engage in any negotiations or discussions with any

otherwise  facilitate  any  effort  or  attempt  to  induce  or  implement,  any

assets (otherwise than as permitted by Section 4.05) or securities of NSS or any
of its  subsidiaries.  NSS will immediately cease and cause to be terminated any
existing  activities,  discussion  or  negotiations  with any parties  conducted

steps to inform the  individuals  or entities  referred to in the first sentence
hereof of the obligations


                                      A-25


<PAGE>


undertaken in this Section. In addition,  NSS 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 NSS or any of its

more of outstanding NSS Stock (including  shares  beneficially  held) to execute

by Thompson  Coburn in  connection  with the  issuance of one or more of the Tax

     Section  4.17  DIRECTORS  AND  OFFICERS  INSURANCE.  NSS  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
NSS. NSS shall renew any existing D&O Insurance or purchase any discovery period
D&O Insurance provided for thereunder at Summits request.

     Section 4.18. CONFORMING ENTRIES.

     (a)  Notwithstanding  that NSS believes that NSS 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,  NSS 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,  NSS and Summit  shall  consult  and  cooperate  with each other with
respect to  conforming  the loan,  accrual and  reserve  policies of NSS and its
subsidiaries  to those policies of Summit,  as specified in each case in writing
to NSS, based upon such consultation and as hereinafter provided.

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

     (c) NSS and Summit shall consult and cooperate with each other with respect
to  determining  the  amount  and  the  timing  for  recognizing  for  financial
accounting  purposes NSS'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 4.19, it is the
objective  of  NSS  and  Summit  that  such  reserves,   accruals,  charges  and
divestitures,  if any, to be taken shall be consistent  with generally  accepted
accounting principles.

     Section 4.19  COOPERATION  WITH POLICIES AND PROCEDURES.  NSS, 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
4.19 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 NSSs existing policies and procedures in respect thereof, unless
to do so would cause NSS


                                      A-26


<PAGE>


or any of its  subsidiaries to be in violation of any law, rule or regulation or
requirement of any governmental  regulatory  authority having  jurisdiction over
NSS or any of its subsidiaries affected thereby.

     Section  4.20  ENVIRONMENTAL  REPORTS.  NSS shall  disclose  to Summit  all
matters of the types  described  in Section 2.22 above which NSS would have been
required  to  disclose  to Summit on the date hereof if known to NSS on the date
hereof,  as such become  known to NSS between the date hereof and the  Effective
Time. In addition,  Summit may 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 NSS or any of its  subsidiaries  as of the date of this
Agreement (but excluding space in retail or similar establishments leased by NSS
for automatic  teller machines or leased bank branch  facilities where the space
leased by NSS  comprises  less than 20% of the total space leased to all tenants
of such  property),  and (ii) within 15 days after being  notified by NSS 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 NSS for automatic
teller machines or leased bank branch  facilities  where the space leased by NSS
comprises  less  than 20% of the  total  space  leased  to all  tenants  of such
property).  If the  results  of the phase  one  investigation  indicate,  in the
reasonable opinion of Summit, that additional investigation is warranted, Summit
may at its expense,  within 15 days after  receipt of the  particular  phase one
report,  perform  or cause to be  performed  a phase  two  investigation  on the
property or  properties  deemed by Summit to warrant  such  additional  study or
notify NSS and an environmental consulting firm within 15 days after the receipt
of the particular phase one report that the environmental consulting firm should
promptly commence a phase two investigation.  If the cost of taking all remedial
or other  corrective  actions and measures (as  required by  applicable  law, as
recommended or suggested by phase one or phase two  investigation  reports 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.



                                   ARTICLE V.

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
competitive  or  other  commercial   purposes.   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
NSS, (y) was then generally known to the public,  or (z) was disclosed to Summit
by a third party not bound by an obligation of


                                      A-28



<PAGE>


confidentiality;  or (ii)  disclosures  made as  required  by law. It is further
agreed that if, in the absence of a protective  order or the receipt of a waiver
hereunder,  Summit  is  nonetheless,  in the  written  opinion  of its  counsel,
compelled to disclose information concerning NSS 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 NSS 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 of the  Code or (ii)  materially  impede  or delay  receipt  of any
Required Consent or the  consummation of the  transactions  contemplated by this
Agreement for more than 60 days.

     Section 5.10. INDEMNIFICATION.

     (a) Summit  shall  indemnify,  and advance  expenses in matters that may be
subject to  indemnification  to, persons who served as directors and officers of
NSS or any  subsidiary  of NSS on or before the  Effective  Time with respect to
liabilities and claims (and related  expenses,  including fees and disbursements
of counsel) made against them  resulting from their service as such prior to the
Effective  Time in  accordance  with and subject to the  requirements  and other
provisions of the Restated Certificate of Incorporation and By-Laws of Summit in
effect on the date of this  Agreement  and  applicable  provisions of law to the
same extent as Summit is obliged thereunder to indemnify and advance expenses to
its own  directors  and  officers  with respect to  liabilities  and claims made
against them resulting from their service for Summit;  provided,  however,  that
during  such  time as NSS or any  subsidiary  of NSS  shall  remain  a  separate
corporate entity organized under the laws of the State of Connecticut,  then the
indemnification and advancement of expenses provided for in this Section 5.01(a)
for the directors and officers of such separate  corporate  entity shall be made
in  accordance  with and  subject  to the  requirements  of the  certificate  of
incorporation and by-laws of the particular  separate corporate entity in effect
on the date of this Agreement and applicable provisions of Connecticut law.

     (b) Subject to NSSs  obligation  set forth at Section 4.18: For a period of
six (6) years after the  Effective  Time,  Summit  will use its best  efforts to
provide  to the  persons  who  served as  directors  or  officers  of NSS or any
subsidiary of NSS 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 NSS 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 NSS 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 NSS 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 a NSS Plan which is, respectively, a defined contribution plan,


                                      A-29


<PAGE>


defined  benefit plan or health and welfare plan  available to all NSS employees
generally,  then,  if such NSS Plan is  terminated  by  Summit  or is  otherwise
rendered  inactive by Summit,  Summit shall offer to the former employees of NSS
affected by such plan  termination  or cessation of activity the  opportunity to
participate in the similar plan of Summit.

     (b)  Summit  shall  assume  the   obligations  of  NSS  under  the  Officer
Agreements.

     (c)  Members of the Board of  Directors  of Bank on the date  hereof  (Bank
Board  Members)  shall be entitled to continue their service as Directors of the
Bank after the Effective  Time until the earlier to occur of (i) the  expiration
of one year  following  the  Effective  Time,  or (ii) the merger of Bank into a
wholly owned bank subsidiary of Summit not organized under the laws of the State
of Connecticut (the Bank Merger),  provided that if the Bank Merger occurs prior
to the expiration of a one year period  following the Effective Time, Bank Board
Members  may  continue  to serve for the  balance  of such one year  period on a
separately constituted  Connecticut advisory board of directors to the surviving
bank in the Bank Merger,  and provided further that service on the Bank Board of
Directors  after the Effective  Time shall  continue to be subject to applicable
provisions of the Banks  certificate of  incorporation,  by-laws and Connecticut
law.

                             [LETTER HEAD TO COME]




                                                                  , 1998


Board of Directors
NSS Bancorp, Inc.
48 Wall Street
Norwalk, CT 06850

Gentlemen:

     NSS Bancorp, Inc. ("NSS") and Summit Bancorp ("Summit") have entered into a
Reorganization Agreement, dated as of June 17, 1998 (the "Agreement"),  pursuant
to  which  NSS  will  be  acquired  by  Summit  (the   "Reorganization").   Upon
consummation of the  Reorganization,  each share of NSS common stock,  par value
$.01 per share (together with the rights attached thereto issued pursuant to the
Rights  Agreement  dated  as  of  May  10,  1996  between  NSS  and  ChaseMellon
Shareholder  Services,  LLC,  as Rights  Agent,  the "NSS  Shares"),  issued and
outstanding  immediately prior to the Reorganization,  other than certain shares
specified in the  Agreement,  will be converted  into the right to receive 1.232
shares (the "Exchange  Ratio") of Summit common stock,  par value $.80 per share
(together  with the  rights  attached  thereto  issued  pursuant  to the  Rights
Agreement  dated as of August 16, 1989 between  Summit and First  Chicago  Trust
Company  of New  York,  as  Rights  Agent).  The  terms  and  conditions  of the
Reorganization are more fully set forth in the Agreement. You have requested our
opinion as to the  fairness,  from a financial  point of view,  of the  Exchange
Ratio to the holders of NSS Shares.

     Sandler  O'Neill  &  Partners,  L.P.,  as  part of its  investment  banking
business,  is regularly  engaged in the valuation of financial  institutions and
their securities in connection with mergers and acquisitions and other corporate
transactions.  In connection  with this opinion,  we have reviewed,  among other
things: (i) the Agreement and exhibits thereto; (ii) the Stock Option Agreement,
dated June 18,  1998,  by and  between NSS and Summit;  (iii)  certain  publicly
available financial statements of NSS and other historical financial information
provided  by NSS  that we  deemed  relevant;  (iv)  certain  publicly  available
financial  statements  of Summit  and  other  historical  financial  information
provided by Summit that we deemed relevant;  (v) certain financial  analyses and
forecasts of NSS prepared by and reviewed  with  management of NSS and the views
of  senior   management  of  NSS  regarding  NSS's  past  and  current  business
operations,  results thereof,  financial  condition and future  prospects;  (vi)
certain financial analyses and forecasts of Summit prepared by and reviewed with
management  of Summit  and the views of senior  management  of Summit  regarding
Summit's  past and  current  business  operations,  results  thereof,  financial
condition   and   future   prospects;   (vii)  the  pro  forma   impact  of  the
Reorganization;  (viii)  the  publicly  reported  historical  price and  trading
activity for NSS's and Summit's common stock,  including a comparison of certain
financial and stock market  information for NSS and Summit with similar publicly
available  information  for certain other  companies the securities of which are
publicly traded; (ix) the financial terms of recent business combinations in the
savings institution industry, to the extent publicly available;  (x) the current
market environment generally and the banking environment in particular; and (xi)
such other  information,  financial  studies,  analyses and  investigations  and
financial, economic and market criteria as we considered relevant.

     In  performing  our  review,  we have  assumed  and  relied  upon,  without
independent  verification,  the accuracy and  completeness  of all the financial
information,  analyses  and other  information  that was  publicly  available or
otherwise  furnished to,  reviewed by or discussed with us, and we do not assume
any responsibility or liability for the accuracy or completeness thereof. We did
not make an  independent  evaluation  or appraisal of the specific  assets,  the
collateral  securing assets or the liabilities  (contingent or otherwise) of NSS
or Summit


                                      B-1


<PAGE>


or any of their subsidiaries, or the collectibility of any such assets, nor have
we been furnished with any such  evaluations or appraisals.  With respect to the
financial  projections reviewed with management,  we have assumed that they have
been  reasonably  prepared  on bases  reflecting  the best  currently  available
estimates and judgments of the respective  managements of the respective  future
financial  performances  of NSS and  Summit and that such  performances  will be
achieved,  and we express no opinion  as to such  financial  projections  or the
assumptions on which they are based. We have also assumed that there has been no
material change in NSS's or Summit's  assets,  financial  condition,  results of
operations,  business or prospects  since the date of the most recent  financial
statements made available to us. We have assumed in all respects material to our
analysis  that NSS and Summit  will  remain as going  concerns  for all  periods
relevant  to  our  analyses,  that  all of the  representations  and  warranties
contained in the Agreement and all related agreements are true and correct, that
each party to such agreements  will perform all of the covenants  required to be
performed by such party under such agreements and that the conditions  precedent
in the Agreement are not waived.

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

     We  have  acted  as  NSS's   financial   advisor  in  connection  with  the
Reorganization and will receive a fee for our services, a significant portion of
which is  contingent  upon  consummation  of the  Reorganization.  We will  also
receive a fee for  rendering  this  opinion.  In the past, we have also provided
certain other investment banking services for NSS and have received compensation
for such services.

     In the ordinary  course of our business,  we may actively  trade the equity
securities  of NSS and Summit for our own  account  and for the  accounts of our
customers  and,  accordingly,  may at any time hold a long or short  position in
such securities.

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

hereof,  that the Exchange Ratio is fair, from a financial point of view, to the
holders of NSS Shares.

                    NSS BANCORP, INC. STOCK OPTION AGREEMENT

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

     STOCK  OPTION  AGREEMENT,  dated as of the 18th  day of  June,  1998  (this
"Agreement"), between Summit Bancorp., a New Jersey corporation ("Grantee"), and
NSS Bancorp, Inc., a Connecticut corporation ("Issuer").




                             W I T N E S S E T H :

     WHEREAS,  Grantee  and  Issuer  have on a date  prior to the  date  hereof,
entered into an Agreement and Plan of  Reorganization,  dated as of the 17th day
of June, 1998 (the "Reorganization Agreement").  (Capitalized terms used in this
Agreement  and not defined  herein but defined in the  Reorganization  Agreement
shall have the meanings assigned thereto in the Reorganization Agreement); and

     WHEREAS,  as a condition  and  inducement  to Grantee's  entering  into the
Reorganization  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 Reorganization Agreement, the parties
hereto agree as follows:

     Section 1. GRANT OF OPTION; BREAKUP FEE.

     (a) Issuer  hereby  grants to  Grantee,  subject to the  further  terms and
       conditions in this Agreement:

   (1)  an unconditional, irrevocable option ("Option A") to purchase, after the
        time and date the shareholders of Issuer have approved this Agreement in
        accordance  with  the  first  paragraph  of  Article  THIRTEENTH  of the
        Certificate  of  Incorporation  of Issuer,  up to 494,629 fully paid and
        nonassessable  shares of the common stock, par value $0.01 per share, of
        Issuer  ("Common  Stock")  at a price  equal to $45.00  per share  (such
        price, as adjusted as hereinafter provided, the "Option Price"); and

   (2)  an unconditional,  irrevocable option ("Option B") to purchase, prior to
        the  time and  date  the  shareholders  of  Issuer  have  approved  this
        Agreement in accordance with the first  paragraph of Article  THIRTEENTH
        of the Cerrtificate of Incorporation of Issuer, up to 248,308 fully paid
        and  nonassessable  shares of the  Common  Stock of Issuer at the Option
        Price per share.

     (b) The term  Option  as used in this  Agreement  shall  mean  Option A and
Option B considered collectively.

     (c) In the event the Option becomes  exerciseable at such time as the terms
governing  Option B are  applicable,  Issuer agrees to pay Grantee a breakup fee
equal to $3,500,000 (the Breakup Fee) in accordance with Section 2.

     (d) 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  (subject to the terms and  conditions
governing  the  mutually  exclusively  exerciseability  of each of  Option A and
Option B set forth in Section  1(a)  above),  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


                                      C-1


<PAGE>


to the Effective Time, (ii) the termination of the  Reorganization  Agreement in
accordance with the terms thereof prior to the occurrence of an Extension Event,
other than a termination of the Reorganization Agreement by the Grantee pursuant
to Section  9.02(a)(2) or Sections 9.02(b),  (c) or (d)(2) thereof,  or (iii) 15
months after the  termination  of the  Reorganization  Agreement  following  the
occurrence of an Extension Event (as defined  below),  or the termination of the
Reorganization  Agreement by Grantee pursuant to Section  9.02(a)(2) or Sections
9.02(b),  (c) or (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  Reorganization  Agreement  and, if the
Reorganization  Agreement has not terminated  prior  thereto,  such breach would
entitle Issuer to terminate the Reorganization  Agreement.  The events described
in clauses (i) (iii) in the  preceding  sentence  are  hereinafter  collectively
referred to as Exercise Termination Events. As provided in Section 8, the rights
set forth therein shall  terminate  upon an Exercise  Termination  Event and, as
provided in Sections 6 and 7 hereof,  the rights to deliver requests pursuant to
Sections 6 or 7 shall terminate 12 months after an Exercise  Termination  Event,
subject, in such case, to the provisions of Section 9.


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

    (i)Issuer or any of its subsidiaries  (each an "Issuer  Subsidiary"),  shall
       have entered into an  agreement to engage in an  Acquisition  Transaction
       (as defined  below) with any person (the term  "person"  for  purposes of
       this Agreement  having the meaning  assigned  thereto in Sections 3(a)(9)
       and  13(d)(3) of the  Securities  Exchange  Act of 1934,  as amended (the
       "Securities  Exchange Act"),  and the rules and  regulations  thereunder)
       other  than  Grantee  or  any  of  its  subsidiaries   (each  a  "Grantee
       Subsidiary")  or the Board of Directors of Issuer shall have  recommended
       that the  shareholders  of  Issuer  approve  or  accept  any  Acquisition
       Transaction with any person other than Grantee or any Grantee Subsidiary.
       For purposes of this Agreement,  "Acquisition Transaction" shall mean (w)
       a merger or consolidation,  or any similar transaction,  involving Issuer
       or any of Issuer's  banking  subsidiaries  ("Bank  Subsidiaries"),  (x) a
       purchase,  lease or  other  acquisition  of 10% or more of the  aggregate
       value of the assets or deposits of Issuer or any Bank  Subsidiary,  (y) a
       purchase or other acquisition (including by way of merger, consolidation,
       share  exchange or otherwise) of securities  representing  10% or more of
       the voting power of Issuer or a Bank Subsidiary, or (z) any substantially
       similar transaction,  provided,  however,  that in no event shall (i) any
       merger, consolidation or similar transaction involving Issuer or any Bank
       Subsidiary  in  which  the  voting   securities  of  Issuer   outstanding
       immediately  prior  thereto  continue to  represent  (either by remaining
       outstanding or being  converted  into voting  securities of the surviving
       entity of any such transaction) at least 75% of the combined voting power
       of  the  voting   securities  of  the  Issuer  or  the  surviving  entity
       outstanding  after the  consummation  of such merger,  consolidation,  or
       similar  transaction,  or  (ii)  any  internal  merger  or  consolidation
       involving  only Issuer  and/or  Issuer  Subsidiaries,  be deemed to be an
       Acquisition  Transaction,  provided  that  any  such  transaction  is not
       entered into in violation of the terms of the Reorganization 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


                                      C-2


<PAGE>


       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  Reorganization
        Agreement  and such breach (x) would  entitle  Grantee to terminate  the
        Reorganization  Agreement and (y) shall not have been cured prior to the
        Notice Date (as defined below);

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

     (vi) any Purchase Event (as defined below).

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

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

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

   (iii)the  meeting  of  NSS  shareholders  required  by  Section  4.03  of the
        Reorganization  Agreement  shall  not have  been  called by the Board of
        Directors  of  Issuer  or held or  shall  have  been  canceled  prior to
        termination  of  the  Reorganization  Agreement  or  Issuer's  Board  of
        Directors  shall have  withdrawn or modified in a manner  adverse to the
        consummation of the  Reorganization the recommendation of Issuer's Board
        of Directors with respect to the Reorganization  Agreement, in each case
        after an Extension Event.

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

     (e) In the event that  Grantee is entitled  to and wishes to  exercise  the
Option, it shall send to Issuer a written notice (the date of which being herein
referred to as the "Notice  Date")  specifying (i) 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.


                                      C-3

     (f) At the closing  referred to in Section 2(e),  Grantee  shall  surrender
this Agreement  (and the Option granted  hereby) to Issuer and pay to Issuer the
Aggregate Option Price (as defined in this Section 2(f) below) for the shares of
Common Stock  purchased  pursuant to the  exercise of the Option in  immediately
available  funds  by wire  transfer  to a bank  account  designated  by  Issuer;
provided,  however,  that failure or refusal of Issuer to designate  such a bank
account shall not preclude Grantee from exercising the Option.  Aggregate Option
Price  means the amount  obtained by  subtracting  (b) from (a) where (a) is the
amount  obtained by  multiplying  the number of shares with respect to which the
Option is being  exercised by the Option Price,  and (b) is zero unless Option B
is being  exercised  in whole or in part in which  case (b) is the amount of the
Breakup  Fee (or such  portion  of the  Breakup  Fee not in excess of the amount
determined  in clause  (a)).  The terms of this  Section  2(f) are  specifically
intended not to provide a discount from the fair market value of Issuers  Common
Stock on the date the Option is granted and this Agreement  signed,  but instead
to provide  for a  procedure  which (i)  aligns  Grantees  right to receive  the
Breakup Fee with its right to  exercise  Option B in those  circumstances  where
exercise of Option A is unavailable,  and (ii) offsets the obligation of Grantee
to pay the aggregate  purchase price provided for in connection with an exercise
of Option B with the  obligation  of Issuer to pay the  Breakup  Fee and thereby
facilitates and assures Granees receipt of the benefits of the Breakup Fee which
the parties have mutually  agreed  Grantee is entitled to on the terms  provided
for herein.

     (g) At such  closing,  simultaneously  with the  delivery of the  Aggregate
Option Price in immediately  available funds as provided in Section 2(f), Issuer
shall deliver to Grantee a certificate or certificates  representing  the number
of shares of Common  Stock  purchased  by Grantee  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 NSS
   Bancorp,  Inc.  ("Issuer")  dated as of the 18th day of June, 1998. A copy of
   such  agreement  is on file at the  principal  office of  Issuer  and will be
   provided to the holder  hereof  without  charge  upon  receipt by Issuer of a
   written request therefor."

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

   (i) Upon the giving by Grantee to Issuer of the written notice of exercise of
       the Option  provided for in Section 2(e) and the tender of the  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,


                                      C-4


<PAGE>


fully paid,  nonassessable,  and delivered free and clear of all claims,  liens,
encumbrances  and security  interests and not subject to any preemptive  rights;
(ii) that it will not, by  amendment  of its  certificate  of  incorporation  or
through reorganization, consolidation, merger, dissolution or sale of assets, or
by any other voluntary act, avoid or seek to avoid the observance or performance
of any of the covenants,  stipulations or conditions to be observed or performed
hereunder by Issuer;  (iii) promptly to take all action as may from time to time
be required (including (x) complying with all premerger notification,  reporting
and  waiting  period  requirements  specified  in  15  U.S.C.  (section)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, in the case of Option A, 19.9%, and in
the case of Option B, 9.99%, of the number of shares of Common Stock then issued
and outstanding (without  consideration of any shares of Common Stock subject to
or issued pursuant to the Option).

     (b) Whenever the number of shares of Common Stock purchasable upon exercise
hereof is  adjusted as  provided  in this  Section 5, the Option  Price shall be
adjusted by multiplying  the Option Price by a fraction,  the numerator of which
shall be equal to the number of shares of Common Stock  purchasable prior to the
adjustment  and the  denominator of which shall be equal to the number of shares
of Common Stock purchasable  after the adjustment.  In no event shall the Option
Price be adjusted to less than the par value of the Common Stock to be issued at
such Option Price.

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

     Section 6. REGISTRATION RIGHTS.

     (a) DEMAND  REGISTRATION  RIGHTS.  After the occurrence of a Purchase Event
that occurs prior to an Exercise Termination Event, Issuer shall, at the request
of Grantee (whether on its own behalf or on behalf of any


                                      C-5


<PAGE>


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  under the  Securities  Act  relating  to a  delayed  or
continuous offering (as contemplated by Rule 415 of the SEC under the Securities
Act) (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  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


                                      C-6


<PAGE>


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) (1) 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  and in
       connection  therewith  shall pay to Grantee an amount equal to the sum of
       (y) plus (z)


                                      C-7


<PAGE>


       where (y) is the amount by which (A) the  market/offer  price (as defined
       below) exceeds (B) the Option Price,  multiplied by the maximum number of
       shares for which this Option may then be exercised and (z) is the Breakup
       Fee, if Option A is not exerciseable,  unless the Breakup Fee has already
       been paid in connection  with a prior partial  exercise of Option B or is
       zero,  if Option A is  exerciseable  (such amount equal to the sum of (y)
       plus (z) is referred to as the "Option Repurchase Price") and

   (ii) at the request  (the date of such request  being the "Request  Date") of
   the owner of Option Shares from time to time (the "Owner"),  delivered within
   12 months of the  occurrence  of a Repurchase  Event (or such later period as
   provided in Section 9),  Issuer  shall  repurchase  such number of the Option
   Shares from the Owner as the Owner shall  designate  at a price (the  "Option
   Share Repurchase  Price") equal to the  market/offer  price multiplied by the
   number of Option Shares so designated.

     (2) The term  "market/offer  price" shall mean the highest of (i) the price
         per share of Common  Stock at which a tender  offer or  exchange  offer
         therefor has been made by a third party after the date hereof and on or
         prior to the  Request  Date,  (ii) the price per share of Common  Stock
         paid or to be paid by any third  party  pursuant to an  agreement  with
         Issuer (whether by way of a merger,  consolidation or otherwise), (iii)
         the  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


                                      C-8


<PAGE>


Grantee to purchase that number of shares of Common Stock equal to the number of
shares of Common  Stock  purchasable  immediately  prior to the  delivery of the
notice of  repurchase  less the number of shares of Common Stock  covered by the
portion of the Option  repurchased  or (B) to the Owner,  a certificate  for the
number of surrendered  Option Shares covered by the revocation.  For purposes of
this  Section  7(c),  to the extent the Option  Repurchase  Price  includes  the
Breakup  Fee and a  partial  delivery  of the  Option  Repurchase  Price  occurs
pursuant to this Section 7(c), the partial  delivery shall first be allocated as
a payment of the Breakup Fee and second as a  repurchase  of the Option.  To the
extent such partial  delivery is less than the Breakup Fee,  Issuers  obligation
with  respect to the balance of the  Breakup Fee shall  remain in full force and
effect  hereunder  and to the extent the partial  delivery  is greater  than the
Breakup Fee, the shares  purchaseable  pursuant to any new  Agreement  delivered
pursuant to clause (ii)(A) above shall be appropriately adjusted.

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

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

     Section 8. SUBSTITUTE OPTION IN THE EVENT OF CORPORATE CHANGE.

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

     (b) The Substitute Option shall 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.


                                      C-9


<PAGE>


     (d) The following terms have the meanings indicated:

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

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

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

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

     Section 9.  EXTENSION  OF TIME FOR  REGULATORY  APPROVALS.  Notwithstanding
Sections  2(e), 6, 7 and 11, if Grantee has given the notice  referred to in one
or more of such  Sections,  the  exercise  of the rights  specified  in any such
Section shall be extended (a) if the exercise of such rights requires  obtaining
regulatory approvals, to the extent necessary to obtain all regulatory approvals
for the  exercise  of such  rights,  and (b) to the  extent  necessary  to avoid
liability  under Section 16(b) of the Securities  Exchange Act by reason of such
exercise;  provided  that in no event shall any closing  date occur more than 18
months after the related  Notice  Date,  and, if the closing date shall not have
occurred  within such period due to the failure to obtain any required  approval
by the Federal  Reserve Board or any other  Governmental  Authority  despite the
reasonable  efforts of Issuer or the Substitute  Option Issuer,  as the case may
be, to obtain such approvals, the exercise of the Option shall be deemed to have
been rescinded as of the related Notice Date. In the event (a) Grantee  receives
official  notice  that an approval  of the  Federal  Reserve  Board or any other
Governmental  Authority  required for the purchase and sale of the Option Shares
will not be issued or granted or (b) a closing date has not  occurred  within 18
months  after the  related  Notice  Date due to the  failure  to obtain any such
required  approval,  Grantee  shall  be  entitled  to  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,  subject  in the case of Option A to  shareholder
approval  in  accordance  with  Article  THIRTEENTH  of Issuers  Certificate  of
Incorporation, 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, other than in the case of Option A with respect to shareholder  approval in
accordance with Article THIRTEENTH of Issuers  Certificate of Incorporation,  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


                                      C-10


<PAGE>


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 of  incorporation  or by-laws,  or the
comparable governing instruments of any of its subsidiaries, or (ii) a breach or
violation  of,  or a  default  under,  any  agreement,  lease,  contract,  note,
mortgage,  indenture,  arrangement  or  other  obligation  of it or  any  of its
subsidiaries  (with or without the giving of notice,  the lapse of time or both)
or under any law,  rule,  ordinance or  regulation or judgment,  decree,  order,
award or governmental or  non-governmental  permit or license to which it or any
of its subsidiaries is subject, that would in any case give any other person the
ability to prevent or enjoin  Issuer's  performance  under this Agreement in any
material respect.

     Section 11. ASSIGNMENT OF OPTION BY GRANTEE.

     (a) Neither of the parties  hereto may assign any of its rights or delegate
any of its obligations  under this Agreement or the Option created  hereunder to
any other person without the express written consent of the other party,  except
that Grantee may assign this  Agreement to a wholly owned  subsidiary of Grantee
and  Grantee  may  assign  its  rights  hereunder  in whole or in part after the
occurrence of a Purchase Event;  provided,  however, that until the date 15 days
following the date at which the Federal Reserve Board approves an application by
Grantee  under the BHC Act to acquire the shares of Common Stock  subject to the
Option,  Grantee  may not  assign its  rights  under the Option  except in (i) a
widely dispersed public  distribution,  (ii) a private placement in which no one
party acquires the right to purchase securities  representing in excess of 2% of
the  aggregate  voting power of Issuer,  (iii) an  assignment  to a single party
(e.g.,  a broker or  investment  banker) for the purpose of  conducting a widely
dispersed  public  distribution  on Grantee's  behalf,  or (iv) any other manner
approved  by  the  Federal  Reserve  Board.  Grantee  will  pay  any  reasonable
out-of-pocket  costs  and  expenses  of  Issuer  in  connection  with  any  such
assignment. The term "Grantee" as used in this Agreement shall also be deemed to
refer to Grantee's permitted assigns.

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

     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

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

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.

unenforceable,  the  remainder  of  the  terms,  provisions  and  covenants  and
restrictions  contained in this Agreement shall remain in full force and effect,

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.

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,

understandings  with respect thereof,  written or oral. The terms and conditions

rights,  remedies,  obligations  or  liabilities  under  or by  reason  of  this

     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.

Grantor  covenants  that it shall not, and by approving this Agreement the Board

Incorporation  or otherwise to cause any excess shares,  as that term is defined
in said  Article  THIRTEENTH,  held  beneficially  or of  record by Summit to be
transferred to an  independent  trustee for sale on the open market or otherwise
as  permitted by said  Article  THIRTEENTH,  or take any other action or fail to
take any other  action  the effect of which is to impede or  interfere  with the
free exercise of ownership rights of Summit with respect to such Common Stock of
Grantor, other than the restrictions specifically required by Article THIRTEENTH
with respect to voting rights and any  restrictions  imposed on all shareholders
of NSS generally,  and any such action shall be null and void and of no force or
effect against Summit and Summit shall be entitled to apply to a court of equity
to enforce  the  covenants  made in this  Section 25 without the posting of bond
which Grantor hereby waives.

     IN WITNESS  WHEREOF,  each of the parties has caused this NSS Stock  Option
Agreement between NSS Bancorp, Inc., as Issuer, and Summit Bancorp., as Grantee,
to be executed on its behalf by their officers thereunto duly authorized, all as
of the 18th day of June, 1998.

the shares registered in his name only if he dissents with respect to all shares
beneficially  owned by any one person and notifies the corporation in writing of
the name and  address  of each  person on whose  behalf he  asserts  dissenters'
rights.  The rights of a partial  dissenter under this subsection are determined

on  his  behalf  only  if:  (1)  He  submits  to  the   corporation  the  record
shareholder's  written  consent  to the  dissent  not  later  than  the time the
beneficial  shareholder  asserts  dissenters'  rights;  and  (2) he does so with
respect to all shares of which he is the beneficial shareholder or over which he

proceeding  is  commenced  under  subsection  (b) of this section is plenary and
exclusive.  The court may appoint one or more persons as  appraisers  to receive
evidence and recommend  decision on the question of fair value.  The  appraisers
have the powers  described in the order  appointing them, or in any amendment to
it. The dissenters are entitled to the same discovery rights as parties in other
civil proceedings.

     (e) Each  dissenter  made a party to the proceeding is entitled to judgment
(1) for the  amount,  if any,  by which  the court  finds the fair  value of his
shares,  plus interest,  exceeds the amount paid by the corporation,  or (2) for
the fair value, plus accrued  interest,  of his after- acquired shares for which
the corporation elected to withhold payment under section 33-867.

     SEC. 33-872. COURT COSTS AND COUNSEL FEES.

     (a) The court in an appraisal  proceeding  commenced  under section  33-871
shall  determine  all  costs  of  the   proceeding,   including  the  reasonable
compensation and expenses of appraisers  appointed by the court. The court shall
assess the costs against the corporation, except that the court may assess costs
against all or some of the dissenters,  in amounts the court finds equitable, to
the extent the court finds the dissenters acted arbitrarily,  vexatiously or not
in good faith in demanding payment under section 33-868.

     (b) The court may also assess the fees and  expenses of counsel and experts
for the respective  parties,  in amounts the court finds equitable:  (I) Against
the  corporation  and in favor of any or all  dissenters  if the court finds the
corporation  did not  substantially  comply  with the  requirements  of sections
33-860  to  33-868,  inclusive;  or (2)  against  either  the  corporation  or a
dissenter,  in favor of any  other  party,  if the  court  finds  that the party
against whom the fees and expenses are assessed acted  arbitrarily,  vexatiously
or not in good faith with respect to the rights  provided by sections  33-855 to
33-872, inclusive.

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

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


                                      II-1


<PAGE>


   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
   [000c]at any time  thereafter  bring suit against the  Corporation to recover
   the unpaid amount of the claim and, if  successful  in whole or in part,  the
   claimant  shall be entitled to be paid also the expense of  prosecuting  such
   claim,  including  attorney's  fees. It shall be a defense to any such action
   (other  than an action  brought to enforce a claim for  expenses  incurred in
   defending  any  proceeding  in  advance  of its final  disposition  where the
   required  undertaking,   if  any  is  required,  has  been  tendered  to  the
   Corporation)  that the  claimant  has not met the  standard of conduct  which
   makes it  permissible  under  the laws of the  State  of New  Jersey  for the
   Corporation to indemnify the claimant for the amount claimed,  but the burden
   of proving such defense shall be on the  Corporation.  Neither the failure of
   the Corporation  (including its Board of Directors or independent counsel) to
   have made a  determination  prior to the  commencement  of such  action  that
   indemnification  of the claimant is proper in the  circumstances  because the
   claimant has met the applicable  standard of conduct set forth in the laws of
   the State of New  Jersey,  nor an  actual  determination  by the  Corporation
   (including its Board of Directors or  independent  counsel) that the claimant
   has not met such  applicable  standard of conduct,  shall be a defense to the
   action or create a presumption  that the claimant has not met the  applicable
   standard of conduct.

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

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

       (f) The Corporation may maintain  insurance,  at its expense,  to protect
   itself and any corporate agent of the Corporation or other enterprise against
   any expense or liability, whether or not the Corporation would have the power
   to indemnify such person against such expense or liability  under the laws of
   the State of New Jersey.  (g) If any  provision or  provisions of this By-Law
   shall  be  held to be  invalid,  illegal  or  unenforceable  for  any  reason
   whatsoever:  (1) the validity,  legality and  enforceability of the remaining
   provisions of this By-Law (including, without limitation, each portion of any
   section of this  By-Law  containing  any such  provision  held to be invalid,
   illegal  or  unenforceable)  shall  not in any way be  affected  or  impaired
   thereby;  and (2) to the fullest  extent  possible,  the  provisions  of this
   By-Law (including,  without  limitation,  each such portion of any section of
   this By-Law  containing  any such  provision  held to be invalid,  illegal or
   unenforceable)  shall  be  construed  so as to  give  effect  to  the  intent
   manifested by the provision held invalid, illegal or unenforceable.

       (h) For purposes of this By-Law:

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

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


                                      II-2


<PAGE>


       (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;

       (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

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

   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

ITEM 22. UNDERTAKINGS.

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

     (b) The undersigned registrant hereby undertakes:

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

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

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

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

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

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

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

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

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