</TABLE>

     Neither Summit nor, to the best of its knowledge,  any of its directors and
executive  officers  has  during  the past five  years (a) been  convicted  in a
criminal  proceeding  (excluding traffic violations or similar  misdemeanors) or
(b) been a party to a civil proceeding of a judicial or  administrative  body of
competent  jurisdiction  or was or is subject to a  judgment,  decree,  or final
order  enjoining  future  violations of, or prohibiting or mandating  activities
subject  to,  federal or state  securities  laws or finding any  violation  with
respect to such laws.

     All of the above natural persons are citizens of the United States.

Item 3. Source and Amount of Funds or Other Consideration.

     On June 18, 1998, Summit and Issuer, a corporation organized under the laws
of the  State of  Connecticut  and bank  holding  company  registered  under the
federal Bank Holding  Company Act,  entered into a Stock Option  Agreement  (the
"NSS Option Agreement") pursuant to which, in consideration of the covenants and
agreements  of Summit  contained  therein  and in the  Reorganization  Agreement
(defined below), and as an inducement to Summit to enter into the Reorganization
Agreement,  Issuer  granted  to  Summit an option  to  purchase,  under  certain
circumstances,  up to an  aggregate  of 494,629  shares of the  Common  Stock of
Issuer at the per share price of $45.00 (the "NSS Option").

     Summit is not now able to identify  the source of funds which would be used
if it were to exercise the NSS Option in whole or in part. In the event the need
to  exercise  the NSS Option  arises,  Summit  will  determine  at that time the
appropriate  source of the  funds,  up to  approximately  $22,258,305  needed to
exercise the NSS Option.

Item 4. Purpose of the Transaction.

     On June 17, 1998, Summit and Issuer entered into a Reorganization Agreement
(the  "Reorganization   Agreement")  providing  for,  among  other  things,  (i)
alternatively,  the merger of Issuer  into  Summit,  the merger of Issuer into a
wholly owned  subsidiary of Summit or the merger of a wholly owned subsidiary of
Summit into Issuer,  or an exchange of shares of Summit for shares of the Issuer
(any of the foregoing  constituting the  "Reorganization") and (ii) the exchange
of each  outstanding  share of the Common Stock of Issuer ("Issuer  Common") for
1.232 shares of the Common Stock of Summit  ("Summit  Common"),  with cash being
paid in lieu of  issuing  fractional  shares  of  Summit  Common;  all  upon the
satisfaction  of the  terms  and  conditions  set  forth  in the  Reorganization
Agreement,  including the receipt of approval from the  shareholders  of Issuer,
the  Board of  Governors  of the  Federal  Reserve  System  and the  Connecticut
Department  of  Banking.  NSS has the  right  to  terminate  the  Reorganization
Agreement if the average price of Summit  Common  during the trading  period set
forth in the  Reorganization  Agreement and a quotient with respect  thereto are
less than certain thresholds set forth in the Reorganization Agreement.

     On June 18, 1998, in connection with and in  consideration of the execution
of the  Reorganization  Agreement,  Issuer granted to Summit the NSS Option,  an
option to purchase, under certain circumstances,  up to 494,629 shares of Issuer
Common at a per share exercise price equal to $45.00.  The exercise price of the
NSS Option was arrived at by mutual agreement of the parties.

     Summit  and  Issuer,  in  accordance  with the terms of the  Reorganization
Agreement,  plan to reorganize Issuer with and into Summit upon the satisfaction
of all conditions set forth in the Reorganization  Agreement. The NSS Option was
acquired  by Summit  and  granted by Issuer for the  purpose of  decreasing  the
likelihood that third parties would initiate actions,  including the acquisition
of  significant  amounts  of the Common  Stock of  Issuer,  having the effect of
interfering with the contractual  relationship established by the Reorganization
Agreement or hindering the  consummation of the  Reorganization  contemplated by
the parties and of assisting  Issuer,  if necessary,  in obtaining the requisite
shareholder approval of the Reorganization.

Item 5. Interest in Securities of the Issuer.

     (a) Prior to June 18,  1998,  Summit  was the  beneficial  owner of 105,500
shares of Issuer Common.  On June 18, 1998, Summit acquired the right and option
to acquire up to 494,629  shares of Issuer  Common  pursuant  to the NSS Option.
Summit  disclaims  beneficial  ownership  of the shares which could be acquired,
under certain circumstances, pursuant to the NSS Option, inasmuch as such option
is currently not exerciseable within 60 days.

     The 105,500 shares of Issuer Common held by Summit represent less than five
percent of the issued and  outstanding  common  stock of the Issuer and together
with the 494,629 shares of Issuer Common Stock which could be acquired under the
circumstances set forth in the NSS Option,  as to which beneficial  ownership is
disclaimed,  represent  20.9% of the  issued  and  outstanding  Common  Stock of
Issuer, treating the 494,629 shares of Common Stock of Issuer covered by the NSS
Option as issued and  outstanding  for  purposes of  calculating  the  foregoing
percentage.

     As of June 18,  1998 and during the period  from June 18,  1998 to the date
hereof, to the knowledge of Summit, no directors or executive officers of Summit
beneficially owned any shares of Issuer Common.

     (b) Summit  possesses  sole power to vote and dispose of the 105,500 shares
of Issuer Common acquired by Summit prior to June 18, 1998.

     Summit   possesses  the  sole  power  to  exercise  the  NSS  Option  until
termination  occurring  in  accordance  with its terms.  The NSS Option does not
carry any voting  rights.  Upon  exercise of the NSS Option in whole or in part,
Summit would  possess the sole power to vote and dispose of the shares of Issuer
Common  acquired  thereby,   subject  to  certain  conditions  and  restrictions
contained in the Stock Option Agreement.

     (c) During the 60 days preceding the execution of the NSS Option  Agreement
neither  Summit nor,  to the  knowledge  of Summit,  any  director or  executive
officer of Summit effected any transaction in the Common Stock of NSS

     (d) Not Applicable.

     (e) Not Applicable.

Item 6.   Contracts, Arrangements, Understandings, or Relationships with
          Respect to Securities of the Issuer.

          See response to Items 3 and 4 and The Reorganization Agreement and NSS
     Option Agreement  constituting Exhibits 10(a) and 10(b),  respectively,  to
     this Schedule 13D. No others exist.

         (b)  Summit  shall  prior to the  Effective  Time  elect the method for
carrying out the  Reorganization  from among those  methods set forth at Section

         Section 1.02.  Capital Stock of Summit. All shares of the capital stock
of Summit issued or issued and  outstanding  immediately  prior to the Effective
Time,  including the Common Stock,  par value $.80 per share,  of Summit and the
rights attached thereto ("Summit Rights") pursuant to the Rights Agreement dated
as of August 16, 1989  between  Summit and First  Chicago  Trust  Company of New

         (a) At the Effective Time, by virtue of the  Reorganization and without

                  (1) All shares of the Common Stock,  par value $.01 per share,
of NSS and the rights  attached  thereto ("NSS  Rights")  pursuant to the Rights
Agreement  dated as of May 10,  1996  between  NSS and  ChaseMellon  Shareholder

Section 1.07(c) below) shall be converted into the right to receive whole shares
of  Summit  Stock  and cash in lieu of  fractional  shares  of  Summit  Stock as
follows:  the  aggregate  number  of  shares  of NSS  Stock  held  by  each  NSS
Shareholder  shall be  multiplied  by the Exchange  Ratio (as defined at Section

shall equal the whole number  resulting from the foregoing  multiplication,  and
(ii) the cash in lieu of a  fractional  share of  Summit  Stock  ("Cash  In Lieu
Amount") a NSS  Shareholder  shall become  entitled to receive  pursuant to this
Section 1.03(a)(2) shall equal the

                                       -2-
<PAGE>

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
"Shares").   (The  Shares  and  any  Cash  In  Lieu   Amounts   payable  in  the
Reorganization,  both  adjusted as and if necessary in  accordance  with Section
1.03(b)   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 the  Reorganization.  Summit shall reserve and make available for issuance to
holders of NSS Stock in  connection  with the  Reorganization,  on the terms and
subject to the conditions of this Agreement,  sufficient  shares of Summit Stock
to effect the conversion  contemplated by Section 1.03 and related terms of this
Agreement,  which shares,  when issued and delivered,  will be duly  authorized,
legally  and validly  issued,  fully paid and  non-assessable  and subject to no
preemptive  rights.  Upon  the  terms  and  subject  to the  conditions  of this
Agreement,  particularly  Sections 1.03 and 1.07,  Summit shall issue the Shares
upon the effectiveness of the Reorganization to NSS Shareholders.

         Section 1.05. Exchange Agent Arrangements. Prior to the Effective Time,
Summit shall appoint First Chicago Trust Company of New York, or another  entity
reasonably  satisfactory  to  NSS,  as the  exchange  agent  ("Exchange  Agent")

Summit shall deliver to the Exchange Agent  sufficient  Summit  Certificates and
cash as shall be required to satisfy  Summit's  obligations to NSS  Shareholders
under 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 Time") specified in such of the following as shall be applicable:

                  (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,  which time and date shall be identical in the event two certificates of
merger are required; and

                                       -3-
<PAGE>

                  (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 filed by the Connecticut Act.

         (b) The  certificate  or  certificates  of  merger  or  certificate  of
exchange  determined to be applicable to the  Reorganization  in accordance with
Section  1.06(a) is (are  collectively)  referred  to in this  Agreement  as the
Reorganization Certificate.

         (c) In the  event  the  corporate  law of the  jurisdiction  in which a
Reorganization   Certificate   is  required  to  be  filed   requires  that  the
Reorganization  Certificate  set forth,  as the case may be in  accordance  with
Summit's 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
merger"to 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  provisions  governing
SummitSub's  role in such merger,  and such other terms and conditions as Summit
shall  determine  in  its  discretion  to  be  desirable,  including  terms  and
conditions  governing  certificates or 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 be  received  by
Shareholders  of NSS or (z)  materially  impede  or  delay  consummation  of the
transactions contemplated by this Agreement.

         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

                                       -4-
<PAGE>

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:

                                       -5-
<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 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.

                      REPRESENTATIONS AND WARRANTIES OF NSS

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

         Section 2.01.     Organization, Capital Stock.

         (a) Each of NSS and its  nonbank  subsidiaries,  including  the nonbank
subsidiaries  of  bank  subsidiaries  (the  term  "subsidiary",  as used in this
Agreement, shall mean any corporation or other organization of which 10% or more
of the shares or other interests  having by their terms ordinary voting power to
elect a majority of the Board of  Directors  or other group  performing  similar
functions with respect to such corporation or other  organization is directly or
indirectly  owned;  the term  "indirect"  ownership  means  ownership  through a
succession of one or more other subsidiaries), all of which are listed, together
with their respective states of incorporation and direct and indirect beneficial
owners,  on NSS Schedule  2.01(a),  is a  corporation  duly  organized,  validly
existing and in good standing under the laws of the state of its  incorporation,
qualified to transact  business  under the laws of all  jurisdictions  where the
failure to be so qualified would be likely to have a material  adverse effect on
(i) the business,  results of operations,  assets or financial  condition of NSS
and its  subsidiaries,  on a consolidated  basis,  or (ii) the ability of NSS to
perform its obligations  under, and to consummate the transactions  contemplated
by, this Agreement  ("NSS Material  Adverse  Effect").  However,  a NSS Material
Adverse Effect or NSS Material Adverse Change (as defined at Section 2.03 below)
will not  include a change  resulting  from a change in law,  rule,  regulation,
generally accepted or regulatory  accounting principle or other matter affecting
banking  institutions  or their holding  companies  generally or from charges or
expenses  incident  to  the   Reorganization.   Each  of  NSS  and  its  nonbank
subsidiaries  has all corporate  power and authority and all material  licenses,
franchises,  certificates,  permits and other governmental  authorizations which
are legally  required to own and lease its properties and assets,  to occupy its
premises and to engage in its business and  activities as presently  engaged in,
and each has  complied  in all  material  respects  with  all  applicable  laws,
regulations and orders.

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

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

         (d) (1) The  authorized  capital  stock of NSS  consists  of  7,000,000
shares of Common Stock, par value $0.01 per share,  with the NSS Rights attached
thereto  pursuant to the NSS Rights  Agreement,  of which  2,485,571  shares are
issued and  outstanding,  and 500,000 shares of Preferred Stock, par value $0.01
per  share,  of which no shares are issued or  outstanding  and 2,485  shares of
Series A Junior  Participating  Preferred  Stock are reserved for issuance.  All
issued and  outstanding  shares of the  capital  stock of NSS and of each of its
nonbank  subsidiaries  have been fully paid,  were duly  authorized  and validly
issued, are nonassessable and have been issued pursuant to an effective


                                       -8-

"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.

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

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

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

         (e) NSS  owns no bank  subsidiary  other  than  the NSS  Bank  ("Bank")
("bank" is hereby defined to include  commercial banks,  savings banks,  private
banks,  trust  companies,  savings  and  loan  associations,  building  and loan
associations and similar institutions receiving deposits and making loans). Bank
is a bank duly  organized,  validly  existing,  and in good  standing  under the
jurisdiction of its organization and is qualified to transact business under the
laws of all  jurisdictions  where the failure to be so qualified would be likely
to have a NSS Material Adverse Effect. Bank is duly

                                       -9-
<PAGE>
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 NSS's (a) annual report to shareholders  for the fiscal year ended December
31,  1997,  (b) annual  report on Form 10-K  filed  pursuant  to the  Securities
Exchange  Act of 1934,  as amended  ("Exchange  Act") for the fiscal  year ended
December 31, 1997 and (c) 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:

                                      -10-
<PAGE>

         (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

         (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 NSS's  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

                                      -11-
<PAGE>
resolve to the satisfaction of the applicable  regulatory agency any significant
deficiencies cited by any such agency in its most recently completed examination
of each aspect of Bank's and of NSS's  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 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 NSS's  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

                                      -12-
<PAGE>

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 subsidiaries  has since March 31, 1998: (a) (i) declared,  set aside or paid
any dividend or other  distribution in respect of its Equity  Securities,  other
than dividends from  subsidiaries  to NSS or other  subsidiaries  of NSS, and an
ordinary cash dividend to NSS shareholders of $0.10 per share or less per fiscal
quarter,  or,  (ii)  directly or  indirectly  purchased,  redeemed or  otherwise
acquired any shares of any Equity Securities;  (b) incurred current  liabilities
since  that  date  other  than in the  ordinary  course of  business;  (c) sold,
exchanged  or otherwise  disposed of any of their assets  except in the ordinary
course of  business;  (d) except with  respect to any  employment  agreement  or
termination  agreement  disclosed in and appended in its entirety (including any
amendments)  to NSS Schedule  2.09  ("Officer  Agreements"),  made any officers'
salary  increase or wage increase not consistent  with past  practices,  entered
into any employment,  consulting,  severance or change of control  contract with
any present or former director,  officer or salaried employee, or instituted any
employee or director welfare, bonus, stock option,  profit-sharing,  retirement,
severance or other benefit plan or  arrangement or modified any of the foregoing
so as to increase  its  obligations  thereunder  in any  material  respect;  (e)
suffered  any  taking  by  condemnation  or  eminent  domain  or  other  damage,
destruction  or loss in excess of $50,000,  whether or not covered by insurance,
adversely  affecting its business,  property or assets,  or waived any rights of
value in excess of $50,000;  (f)  entered  into  transactions  other than in the
ordinary  course of business which in the aggregate  exceeded  $100,000;  or (g)
acquired assets or capital stock of another company of whatsoever amount, except
in a fiduciary  capacity or in the course of  securing  or  collecting  loans or
leases.

         Section  2.10.  Allowance  for  Credit  Losses.  At 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 NSS's  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

                                      -13-
<PAGE>

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
NSS's 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,  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.

                                      -14-
<PAGE>
         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 NSS's
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,  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

                                      -15-
<PAGE>

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
Plan's  qualification  and  the  associated  trust's  exemption  or  impose  any
liability or penalty under the Code, or (ii) a participant  or  beneficiary or a
nonparticipating employee has been denied benefits properly due or to become due
under such 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

                                      -16-
<PAGE>
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  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 Plan's  qualification  and
any  associated  trust's  exemption or impose any liability or penalty under the
Code; or (ii) a participant or beneficiary  or a  nonparticipating  employee has
been denied  benefits  properly due or to become due under the 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 NSS's 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

                                      -17-
<PAGE>
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 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 NSS's 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  NSS's  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

                                      -18-
<PAGE>
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

bound.

         (b) All such interest rate swaps,  caps,  floors and option  agreements
and other interest rate risk management  arrangements to which NSS or any of its
subsidiaries  is a party or by which any of their  properties  or assets  may be
bound were entered into the ordinary  course of business and, in accordance with

without error relating to date data,  specifically  including any error relating
to, or the  product  of,  date  data that  represents  or  references  different
centuries or more than one century.

                                  ARTICLE III.

                    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.

                                      -22-
<PAGE>

         (b) Summit is qualified to transact business in and is in good standing
under the laws of all  jurisdictions  where the failure to be so qualified would
have a material  adverse  effect on (i) the  business,  results  of  operations,
assets or financial condition of Summit and its subsidiaries,  on a consolidated
basis,  or (ii) the ability of Summit to perform its obligations  under,  and to
consummate the transactions  contemplated by, this Agreement (a "Summit Material
Adverse Effect").  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  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.

                                      -23-
<PAGE>

         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
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

                                      -24-
<PAGE>
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  Agreement.  Approval  by the  shareholders  of Summit of this
Agreement, the 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 ss.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 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

                                      -25-
<PAGE>
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:

for 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

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

which, if determined  adversely to NSS or any of its subsidiaries,  would have a
NSS Material  Adverse Effect or an adverse material effect on the ability of the
parties to timely consummate the  Reorganization  and the related  transactions,
(e)  any  governmental  complaint,  investigation,   hearing,  or  communication
indicating that such litigation or  administrative  proceeding is  contemplated,
(f) any  written  notice of, or other  communication  relating  to, a default or
event  which,  with  notice or lapse of time or both,  would  become a  default,
received by 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 NSS's Certificate of Incorporation and ByLaws 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 NSS's Certificate of Incorporation the acquisition of NSS

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 4.06.  Operation of Business in Ordinary Course. NSS, on behalf
of itself and its  subsidiaries,  covenants  and agrees  that from and after the
date hereof and until the  Effective  Time,  it and its  subsidiaries:  (a) will
carry on their business  substantially in the same manner as heretofore and will
not  institute  any unusual or novel methods of management or operation of their
properties  or business and will maintain such in their  customary  manner;  (b)
will use their best  efforts  to  continue  in effect  their  present  insurance
coverage on all properties,  assets, business and personnel;  (c) will use their
best efforts to preserve  their  business  organization  intact,  preserve their
present  relationships  with  customers,  suppliers,  and others having business
dealings  with them,  and keep  available  their  present  employees,  provided,
however,  that NSS or any of its  subsidiaries  may  terminate  any employee for
unsatisfactory  performance or other reasonable  business purpose,  and provided
further,  however,  that  NSS will  notify  and  consult  with  Summit  prior to
terminating  any of the five highest  paid  employees of NSS; (d) will use their
best  efforts to  continue  to  maintain  fidelity  bonds  insuring  NSS and its

amounts (not

                                      -29-
<PAGE>

less than present coverage) as are customary, usual and prudent for corporations

do anything  which will cause a breach of or default  under any  representation,
warranty or covenant of NSS or any contract, agreement, commitment or obligation

assets or properties  may be bound or  committed;  and (f) will not change their
methods  of  accounting  in  effect at March 31,  1998,  or change  any of their
methods of reporting  income and deductions for Federal income tax purposes from
those  employed in the  preparation  of their Federal income tax returns for the
taxable  year  ending  March 31,  1998,  except as  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 NSS's  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
carry out the intent of this Agreement; (b) use all reasonable efforts to obtain
consents of all third parties and  governmental  bodies  necessary or reasonably
desirable  for  the  consummation  of  the  transactions  contemplated  by  this
Agreement;  (c) diligently  support this Agreement in any proceeding  before any
regulatory  authority  whose  approval of any of the  transactions  contemplated
hereby  is  required  or  reasonably  desirable  or  before  any  court in which
litigation in respect  thereof is pending;  and (d) use its best efforts so that
the  other  conditions  precedent  to the  obligations  of  Summit  set forth in
Articles VI and VII hereof are satisfied.

         Section 4.08.  Cooperation.  Until the Effective Time, NSS will give to
Summit and to its representatives,  including its accountants, KPMG Peat Marwick
LLP, and its legal counsel,  full access during normal  business hours to all of
its property,  documents,  contracts and records  relevant to this Agreement and
the  Reorganization,  will provide such information with respect to its business
affairs and properties as Summit from time to time may reasonably  request,  and
will cause its managerial employees,  and will use its best efforts to cause its
counsel  and  independent  certified  public  accountants,  to be  available  on
reasonable request to answer questions of Summit's  representatives covering the
business and affairs of NSS or any of its subsidiaries.

         Section 4.09. Copies of Documents. As promptly as practicable,  but not
later than 30 days after the date hereof,  NSS will furnish to or make available
to  Summit  all the  documents,  contracts,  agreements,  papers,  and  writings
referred to in the NSS  Schedules or called for by the list  attached  hereto as
Exhibit C (the "Post-Signing Document List").

         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 impose on NSS or any of its subsidiaries with respect to the  Reorganization
and will promptly cooperate with and furnish information to Summit in connection
with any such requirements  imposed upon Summit or on any of its subsidiaries in
connection with the Reorganization.

         Section  4.11.  Agreements of  Affiliated  Shareholders.  NSS agrees to
furnish to Summit,  not later than 10 business days prior to the date of mailing
of the  Proxy-Prospectus,  a writing  setting  forth the names of those  persons
(which will include all individual and beneficial ownership of NSS Stock by such
persons  and also  identifies  the manner in which all such  beneficially  owned
shares of NSS Stock are  registered on the stock record books of NSS) who in the
written  opinion of Tyler,  Cooper & Alcorn,  L.L.P.,  corporate  counsel to NSS
(which  such  opinion  need be  delivered  only to NSS and  cited  by NSS in its
letter), constitute all the affiliates of NSS for the purposes of Rule 145 under
the  Securities Act (an "NSS  Affiliate")  and NSS shall use its best efforts to
cause  each NSS  Affiliate  to enter  into,  prior to the date of mailing of the
Proxy-Prospectus and effective prior to that date, an agreement, satisfactory in
form and substance to Summit, substantially in the form of Exhibit D-1,

                                      -30-
<PAGE>

with respect to Affiliates  who are directors or officers of NSS or a subsidiary
of NSS, or  substantially in the form of Exhibit D-2, with respect to Affiliates
who are not directors or officers of NSS or a subsidiary  of NSS (an  "Affiliate
Agreement"); provided, however, that until an Affiliate executes and delivers an
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
directors or executive  officers or their respective  related interests shall be
made only in the  ordinary  course of business  and on the same terms and at the
same interest rates as those prevailing for comparable  transactions with others
and shall not involve more than the normal risk of  repayment  or present  other
unfavorable features.

         Section 4.13.  Confidentiality.  All information furnished by Summit to
NSS 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  shall return to Summit all of such written  information and all
documents,  notes,  summaries  or  other  materials  containing,  reflecting  or
referring  to,  or  derived  from,  such  information,   except  that  any  such
confidential  information or notes or abstracts therefrom presented to the Board
of Directors of NSS or any committee thereof for the purpose of considering this
Agreement,  the  Reorganization  and the  related  transactions  may be kept and
maintained by NSS with other  records of Board,  and Board  committee,  meetings
subject to a continuing obligation of confidentiality.  NSS shall, and shall use
its best efforts to cause its  representatives  to, keep  confidential  all such
information,  and shall not directly or indirectly use such  information for any
purposes other than the  performance of this  Agreement.  The obligation to keep
such  information  confidential  shall continue for five years from the date the
proposed Reorganization is abandoned and shall not apply to: (i) any information
which (x) was legally in NSS's  possession  prior to the  disclosure  thereof by
Summit,  (y) was then generally known to the public, or (z) was disclosed to NSS
by a  third  party  not  bound  by an  obligation  of  confidentiality;  or (ii)
disclosures  made as  required  by law.  It is  further  agreed  that if, in the
absence  of a  protective  order or the  receipt of a waiver  hereunder,  NSS is
nonetheless,  in the  written  opinion  of its  outside  counsel,  compelled  to
disclose  information  concerning Summit to any tribunal or governmental body or
agency or else stand liable for contempt or suffer other censure or penalty, NSS
may disclose such  information to such tribunal or  governmental  body or agency
without liability  hereunder and shall so notify Summit. This Section 4.13 shall
survive any termination of this Agreement.

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

         Section 4.15.  Acquisition  Proposals.  NSS agrees that neither NSS nor
any of its subsidiaries nor any of the respective  officers and directors of NSS
or its subsidiaries shall, and NSS shall direct and use its best effort to cause
its  employees,  affiliates,  agents  and  representatives  (including,  without
limitation,  any investment  banker,  broker,  financial or investment  advisor,
attorney  or  accountant  retained  by 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,  provide  any  nonpublic  information,  or  authorize  or enter into any
agreement  or  agreement  in  principle  concerning,  or  recommend,  endorse or
otherwise  facilitate  any  effort  or  attempt  to  induce  or  implement,  any
Acquisition  Proposal  (as  defined  below).  "Acquisition  Proposal"  is hereby
defined

                                      -31-
<PAGE>

to be any offer,  including  an  exchange  offer or tender  offer,  or  proposal
concerning a merger,  consolidation,  or other business  combination or takeover
transaction  involving NSS or any of its  subsidiaries or the acquisition of 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
heretofore  with respect to any of the  foregoing.  NSS will take the  necessary
steps to inform the  individuals  or entities  referred to in the first sentence
hereof of the  obligations  undertaken  in this Section.  In addition,  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  subsidiaries  or assets by another party,  and
will immediately deliver as soon as possible by facsimile transmission,  receipt
acknowledged,  to the Summit  officer  notified as required  above a copy of any
document relating thereto promptly after any such document is received by NSS.

         Section 4.16 Tax Opinion Certificates. NSS shall execute and deliver to
Thompson  Coburn any tax  opinion  certificate  reasonably  required by Thompson
Coburn in  connection  with the  issuance  of the Tax  Opinions  (as  defined at
Section  6.03),  dated  as of the  date  of  effectiveness  of the  Registration
Statement  and as of the Closing Date (and as of the date the Closing  occurs if
different than the Closing Date), and NSS shall use reasonable  efforts to cause
each of its  executive  officers,  directors and holders of five percent (5%) or
more of outstanding NSS Stock (including  shares  beneficially  held) to execute
and deliver to Thompson Coburn any tax opinion  certificate  reasonably required
by Thompson  Coburn in  connection  with the  issuance of one or more of the Tax
Opinions,  dated as of the date of effectiveness  of the Registration  Statement
and as of the Closing  Date (and as of the date the Closing  occurs if different
than the Closing Date).

         Section 4.17  Directors' and Officers'  Insurance.  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 Summit's 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'

                                      -32-
<PAGE>

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 NSS's  existing  policies and  procedures  in respect  thereof,
unless to do so would cause NSS 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.

Section 8.07.

         Section 5.02.  Notice of Adverse  Changes.  Summit will promptly advise
NSS in  writing  of (a)  any  event  occurring  subsequent  to the  date of this

condition  (financial  or  otherwise)  of  Summit  and  its  subsidiaries,  on a
consolidated  basis, and (g) any written notice or other  communication from any
third party  alleging that the consent of such third party is or may be required
in connection with the transactions contemplated by this Agreement including the

         Section 5.03.  Copies of Filings.  Summit shall promptly provide to NSS
and its counsel copies of the application  filed with the Federal Reserve Board,
all  reports  filed  by it with  the SEC on  Forms  10-Q,  8-K and  10-K and all

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

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

         Section 5.06. Unpaid NSS Dividends. By virtue of the Reorganization and

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

         Section  5.08.  Confidentiality.  All  information  furnished by NSS to
Summit or its  representatives  pursuant  hereto  shall be  treated  as the sole
property  of NSS and,  if the  Reorganization  shall not  occur,  Summit and its
representatives  shall  return to NSS all of such  written  information  and all
documents,  notes,  summaries  or  other  materials  containing,  reflecting  or
referring  to,  or  derived  from,  such  information,   except  that  any  such
confidential  information or notes or abstracts therefrom presented to the Board
of Directors of Summit or any committee  thereof for the purpose of  considering
this Agreement,  the Reorganization and the related transactions may be kept and
maintained by Summit with other records of Board, and Board committee,  meetings
subject to a continuing  obligation of confidentiality.  Summit shall, and shall
use its best efforts,  to cause its  representatives  to, keep  confidential all
such information,  and shall not directly or indirectly use such information for
any  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  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

                                      -35-
<PAGE>
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 NSS's obligation set forth at Section 4.18: For a period
of six (6) years after the Effective  Time,  Summit will use its best efforts to
provide  to the  persons  who  served as  directors  or  officers  of 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,

                                      -36-
<PAGE>

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, 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 Bank's  certificate of incorporation,  by-laws and Connecticut
law.

of the Reorganization;  the Required Consents and the transactions  contemplated
hereby shall not be contested  by any federal or state  governmental  authority;
and the Required Consents needed for the Reorganization shall have been obtained
and shall not have been withdrawn or suspended.

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

the terms or conditions of, or assumptions made in, the Tax Opinion, as the case

                                  ARTICLE VIII

                  CONDITIONS PRECEDENT TO THE OBLIGATION OF NSS

connection therewith,  are specifically  permitted by this Agreement;  provided,
however,  that  Summit  agrees that it will not permit any such  transaction  to

                           CLOSING; TERMINATION RIGHTS

         Section  9.01.   Closing.   The  closing  of  the  Reorganization  (the
"Closing") shall take place on the date which is 32 days after the last to occur
of the  following  ("Scheduled  Date"),  unless  Summit,  subject  to the second
sentence of this Section 9.01,  shall  designate a date for the Closing which is
prior to the Scheduled Date in a writing ("Closing  Notice") delivered to NSS at
least five (5) business days prior to the date  designated  therein for Closing,
or unless prior to the Scheduled Date the parties agree to a different date:

         (i)      the date of the approval of the Reorganization by the 
                  shareholders of NSS in accordance with Section 7.09;

         (ii)     if the  transactions  contemplated by this Agreement are being
                  contested  in  any  legal  proceeding,   the  date  that  such
                  proceeding has been brought to a conclusion favorable,  in the
                  judgment  of  Summit  and  NSS,  to  the  consummation  of the
                  transactions  contemplated herein or such prior date as Summit
                  and NSS shall elect,  whether or not such  proceeding has been
                  brought to a conclusion; or

         (iii)    the date of receipt of the last of the Required  Consents (and
                  the  expiration  of any required  waiting  period  required by
                  statute or incorporated into such Required Consents);

and the date of Closing  determined in accordance with the foregoing  provisions
is referred to herein as the "Closing  Date".  Summit will use its best efforts,
to the extent it has  discretion  to set a Closing  Date  pursuant  to the first
sentence of this  Section  9.01,  to set a Closing  Date which is on or prior to
January 2, 1999 and to fullfill its obligation  under this Agreement to close on
such date.  The Closing  shall take place at the office of Summit,  301 Carnegie
Center,  Princeton, New Jersey, commencing at 10:00 a.m. on the date the Closing
is held, unless the parties agree to a different place or commencement  time. At
the Closing,  the parties will exchange  certificates,  legal opinions and other
documents for the purpose of determining whether the conditions precedent to the
obligations of the parties set forth herein have been satisfied or waived. After
all such  conditions  have been  satisfied  or waived,  Summit  shall  cause the
Reorganization  Certificate to be filed as promptly as practicable following the
Closing,  but in no event later than one  business  day  following  the date the
Closing  shall  occur.  All  proceedings  to be taken  and all  documents  to be
executed and  delivered by all parties at the Closing  shall be deemed so taken,
executed and delivered simultaneously,  and no proceedings shall be deemed taken
or any documents  executed or delivered  until all have been taken,  executed or
delivered.

Agreement,  upon voting,  shall have failed to approve the Reorganization,  this
Agreement and the transactions contemplated hereby by the requisite vote;

<PAGE>

                  (2) a  material  breach of a  warranty  or  representation  or
covenant  made by the other  party shall have  occurred  and such breach has not
been  cured,  or is not  capable of being  cured,  within 30 days after  written
notice  of the  existence  thereof  shall  have been  given to the  other  party
(provided  that the  terminating  party is not then in  material  breach  of any
representation, warranty, covenant or other agreement contained herein);

                  (3) NSS's  investment  banker is unable to  deliver  to NSS by
October 31, 1998 the opinion required by Section 8.07; or

                  (4) the Closing is not consummated on or before March 1, 1999,
unless the failure of such  occurrence  shall be due solely to a material breach
of any representation, warranty, covenant or other agreement contained herein by
the party  seeking to terminate  this  Agreement or the failure of such party to
fulfill a  condition  to  Closing  provided  for herein or observe or perform an
agreements set forth in this  Agreement  required to be performed or observed by
such party prior to Closing.

         (b) If either  party shall  refuse to close on the Closing Date because
all the  conditions to its obligation to close set forth in Article VI shall not
have been met, the parties shall conduct the Closing as promptly as  practicable
after all such conditions have been satisfied.  In the event the failure of such
a  condition  is due  to one or  more  material  breaches  of a  representation,
warranty,  covenant or other agreement  contained herein, the Board of Directors
of a party not in breach  may,  during the period  any breach  remains  uncured,
terminate this  Agreement by giving  written  notice of such  termination to the
other party.

         (c) If either  party shall  refuse to close on the Closing Date because
all the  conditions to its  obligation to close set forth in Article VII or VIII
shall not have been met  (other  than a failure  of the  condition  set forth at
Section 7.09 or 8.09 due to the  circumstances  set forth in Section  9.02(a)(1)
hereof,  a  failure  of the  condition  set  forth  at  Section  8.07 due to the
circumstances  set forth at Section  9.02(a)(3) hereof or a refusal of Summit to
close due to a failure of the  condition set forth at Section 7.12 hereof caused
by an act or omission of Summit):  (i) the parties  shall conduct the Closing as
promptly as practicable after all such conditions have been satisfied,  and (ii)
the Board of Directors of such party may, during the period the failed condition
continues, terminate this Agreement by giving written notice of such termination
to the other party unless such party itself has failed to satisfy a condition to
the  other  party's   Closing   obligation  or  is  in  material   breach  of  a
representation, warranty, covenant or other agreement contained herein.

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

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

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

                  (3) as provided at Section 4.20.

                        Name of Affiliate:


   Summit Bancorp.
   301 Carnegie Center
   P.O. Box 2066
   Princeton, New Jersey 08543

   Gentlemen:

         This letter agreement is being entered into pursuant to the terms of
   the Reorganization Agreement, dated June __, 1998 (the "Reorganization
   Agreement"), between Summit Bancorp. ("Summit") and NSS Bancorp, Inc.
   ("NSS"), which provides, among other things, for the reorganization of NSS
   with and into Summit (the "Reorganization") and the conversion at the
   Exchange Ratio provided for in the Reorganization Agreement of shares of the
   common stock, par value $.01 per share, of NSS ("NSS Common Stock")
   outstanding at the Effective Time (as defined in the Reorganization
   Agreement) held in the aggregate by each NSS Shareholder into whole shares of
   the Common Stock, par value $.80 per share, of Summit (the "Summit Common
   Stock") and cash in lieu of a fractional share of Summit Common Stock.

         Shares of NSS Common Stock owned on the date hereof or at any time
   hereafter solely, jointly or in a custodial or other representative capacity
   by me, by a minor child of mine, by a relative sharing the same household as
   me, or by an entity (for example, trusts, estates, partnerships,
   corporations, charitable organizations, foundations) I control, whether such
   shares are owned directly (of record) or indirectly (through a bank, broker
   or other nominee), and any other shares of NSS Common Stock over which I or
   such other persons or entities hold investment or voting powers, either alone
   or with others, are referred to collectively herein as the "NSS Shares".
   Shares of Summit Common Stock to be received in exchange for the NSS Shares
   are referred to collectively herein as the "Summit Shares".

         I have been advised that, in the opinion of counsel, I may be deemed to
   be, at the time the Reorganization is submitted for a vote of the
   shareholders of NSS, an "affiliate" of NSS as that term is defined for
   purposes of paragraphs (c) and (d) of Rule 145 of the Rules and Regulations
   (the "Rules and Regulations") of the Securities and Exchange Commission (the
   "SEC") under the Securities Act of 1933, as amended (the "Act") and that the
   Reorganization Agreement requires that persons so characterized make the
   representations, warranties, covenants and agreements set forth below as a
   condition to Summit closing the Reorganization.

         Capitalized terms used herein but not specifically defined herein shall
   have the meaning ascribed to them in the Reorganization Agreement.


   
                                      D-1-1

<PAGE>

         In consideration of the premises, I represent, warrant, covenant and
agree as follows:

         A. I will not make or permit any sale, transfer or other disposition of
   the Summit Shares, or make or permit any offer to sell, transfer or otherwise
   dispose of the Summit Shares, in violation of the Act or the Rules and
   Regulations.

         B. I have been advised that the issuance of the Summit Shares pursuant
   to the Reorganization has been registered with the SEC pursuant to a
   registration statement under the Act. However, I have also been advised that
   a distribution of the Summit Shares has not been registered under the Act and
   that, because I may be deemed to be, at the time the Reorganization is
   submitted for a vote of the shareholders of NSS, an "affiliate" of NSS, I may
   not make or permit any sale, transfer or other disposition of any of such
   Summit Shares unless and until (i) an offer and sale of such Summit Shares
   has been registered under the Act, (ii) such disposition of such Summit
   Shares is made in conformity with Rule 145 under the Act, or (iii) an
   exemption from registration, in the written opinion of counsel acceptable to
   Summit, is available with respect to such disposition of such Summit Shares.
   In the event of a transfer of Summit Shares permitted by this Agreement, I
   agree that I will obtain, and deliver to you a copy of, an agreement
   substantially similar to this agreement from each transferee of the Summit
   Shares who, in the written opinion of counsel acceptable to Summit, may not
   under the Act dispose of the Summit Shares so transferred without
   registration under the Act.

         C. I understand that Summit is under no obligation to register the
   sale, transfer or other disposition of the Summit Shares or to take any other
   action necessary in order to make compliance with an exemption from
   registration available.

         D. I understand that stop transfer instructions may be given to
   Summit's transfer agent with respect to the Summit Shares and that there may
   be placed on the certificates for such Summit Shares, or any substitutions
   therefor, a legend stating in substance:

        The shares represented by this certificate were issued in a transaction
        to which Rule 145 promulgated under the Securities Act of 1933 applies.
        The shares represented by this certificate may not be sold, transferred,
        or otherwise disposed of unless pursuant to (i) an effective
        registration statement under the Securities Act of 1933, (ii) Rule 145
        or (iii) an exemption from registration under the said Act which is
        available in the opinion of counsel acceptable to Summit Bancorp.

         The legend set forth above and any similar legend placed on any share
   certificate issued upon the transfer of any of the Summit Shares will be
   removed by delivery of substitute certificates without such legend if the
   undersigned, or any person who acquired, directly or indirectly, such Summit
   Shares, shall have delivered to Summit a copy of a letter from the staff of
   the SEC, or a written opinion of counsel acceptable to Summit, to the effect
   that the restrictions on sale, transfer or other disposition referred to in
   this letter are no longer necessary under the Act or otherwise in order to
   effect such sale, transfer or other disposition pursuant to law.

         E. I will vote all of the NSS Shares I now own of record or have voting
   control with

   
                                      D-1-2

<PAGE>



   respect to or hereafter acquire, in favor of the Reorganization (as such
   Reorganization may be effected pursuant to Section 1.01(a)(1), (2) or (3) of
   the Reorganization Agreement) at the meeting of shareholders of NSS to be
   called for the purpose of approving the Reorganization (the "Meeting"). In
   addition, I will not vote any of my NSS Shares in favor of any other merger
   or sale of all or substantially all the assets of NSS to any person other
   than Summit or its affiliates until the termination of the Reorganization
   Agreement or abandonment of the Reorganization by the mutual agreement of NSS
   and Summit, whichever comes first, nor will I transfer my NSS Shares unless
   the transferee, prior to such transfer, executes a voting agreement with
   respect to the transferred shares substantially to the effect of this
   agreement and satisfactory to Summit.

           F. By reason of my knowledge and experience in financial and business
   matters and in my capacity as a director and/or executive officer of a
   financial institution, believe myself capable of evaluating the merits and
   risks of the potential investment in Summit Common Stock contemplated by the
   Reorganization Agreement. I further acknowledge having reviewed the
   Reorganization Agreement and its attachments and that reports, proxy
   statements and other information with respect to Summit filed with the
   Securities and Exchange Commission (the "Commission") were, prior to my
   execution of this agreement, available for inspection and copying at the
   Offices of Commission and that Summit delivered the following such documents
   to NSS:

           (a) Summit's Annual Report on Form 10-K for the year ended December
           31, 1997; and (b) Summit's Quarterly Report on Form 10-Q for the
           quarter ended March 31, 1998.

           G. Summit agrees, by accepting this letter, (a) that for a period of
   two years after the Effective Time (or such shorter period as may be
   permitted by amendments to Rule 145) and thereafter until three months after
   I have ceased to be an affiliate of Summit and so long as Summit has equity
   securities registered pursuant to Section 12 of the Securities Exchange Act
   of 1934, as amended, Summit will make available with respect to itself
   "adequate current public information" as defined in paragraph (c) of Rule 144
   of the Rules and Regulations under the Act.

           I have carefully read this letter and, to the extent I felt
   necessary, discussed with my counsel the requirements of this letter and its
   impact upon the ability to dispose of the NSS Shares and the Summit Shares.


   Accepted this      day of       , 199__              Very truly yours,
   by Summit Bancorp.

                           Name of Affiliate:


   Summit Bancorp.
   301 Carnegie Center
   P.O. Box 2066
   Princeton, New Jersey 08543

   Gentlemen:

         This letter agreement is being entered into pursuant to the terms of
   the Reorganization Agreement, dated June __, 1998 (the "Reorganization
   Agreement"), between Summit Bancorp. ("Summit") and NSS Bancorp, Inc.
   ("NSS"), which provides, among other things, for the reorganization of NSS
   with and into Summit (the "Reorganization") and the conversion at the
   Exchange Ratio provided for in the Reorganization Agreement of shares of the
   common stock, par value $.01 per share, of NSS ("NSS Common Stock")
   outstanding at the Effective Time (as defined in the Reorganization
   Agreement) held in the aggregate by each NSS Shareholder into whole shares of
   the Common Stock, par value $.80 per share, of Summit (the "Summit Common
   Stock") and cash in lieu of a fractional share of Summit Common Stock.

         Shares of NSS Common Stock owned on the date hereof or at any time
   hereafter solely, jointly or in a custodial or other representative capacity
   by me, by a minor child of mine, by a relative sharing the same household as
   me, or by an entity (for example, trusts, estates, partnerships,
   corporations, charitable organizations, foundations) I control, whether such
   shares are owned directly (of record) or indirectly (through a bank, broker
   or other nominee), and any other shares of NSS Common Stock over which I or
   such other persons or entities hold investment or voting powers, either alone
   or with others, are referred to collectively herein as the "NSS Shares".
   Shares of Summit Common Stock to be received in exchange for the NSS Shares
   are referred to collectively herein as the "Summit Shares".

         I have been advised that, in the opinion of counsel, I may be deemed to
   be, at the time the Reorganization is submitted for a vote of the
   shareholders of NSS, an "affiliate" of NSS as that term is defined for
   purposes of paragraphs (c) and (d) of Rule 145 of the Rules and Regulations
   (the "Rules and Regulations") of the Securities and Exchange Commission (the
   "SEC") under the Securities Act of 1933, as amended (the "Act") and that the
   Reorganization Agreement requires that persons so characterized make the
   representations, warranties, covenants and agreements set forth below as a
   condition to Summit closing the Reorganization.

         Capitalized terms used herein but not specifically defined herein shall
   have the meaning ascribed to them in the Reorganization Agreement.

   
                                      D-2-1

<PAGE>



         In consideration of the premises, I represent, warrant, covenant and
agree as follows:

         A. I will not make or permit any sale, transfer or other disposition of
   the Summit Shares, or make or permit any offer to sell, transfer or otherwise
   dispose of the Summit Shares, in violation of the Act or the Rules and
   Regulations.

         B. I have been advised that the issuance of the Summit Shares pursuant
   to the Reorganization has been registered with the SEC pursuant to a
   registration statement under the Act. However, I have also been advised that
   a distribution of the Summit Shares has not been registered under the Act and
   that, because I may be deemed to be, at the time the Reorganization is
   submitted for a vote of the shareholders of NSS, an "affiliate" of NSS, I may
   not make or permit any sale, transfer or other disposition of any of such
   Summit Shares unless and until (i) an offer and sale of such Summit Shares
   has been registered under the Act, (ii) such disposition of such Summit
   Shares is made in conformity with Rule 145 under the Act, or (iii) an
   exemption from registration, in the written opinion of counsel acceptable to
   Summit, is available with respect to such disposition of such Summit Shares.
   In the event of a transfer of Summit Shares permitted by this Agreement, I
   agree that I will obtain, and deliver to you a copy of, an agreement
   substantially similar to this agreement from each transferee of the Summit
   Shares who, in the written opinion of counsel acceptable to Summit, may not
   under the Act dispose of the Summit Shares so transferred without
   registration under the Act.

         C. I understand that Summit is under no obligation to register the
   sale, transfer or other disposition of the Summit Shares or to take any other
   action necessary in order to make compliance with an exemption from
   registration available.

         D. I understand that stop transfer instructions may be given to
   Summit's transfer agent with respect to the Summit Shares and that there may
   be placed on the certificates for such Summit Shares, or any substitutions
   therefor, a legend stating in substance:

        The shares represented by this certificate were issued in a transaction
        to which Rule 145 promulgated under the Securities Act of 1933 applies.
        The shares represented by this certificate may not be sold, transferred,
        or otherwise disposed of unless pursuant to (i) an effective
        registration statement under the Securities Act of 1933, (ii) Rule 145
        or (iii) an exemption from registration under the said Act which is
        available in the opinion of counsel acceptable to Summit Bancorp.

           The legend set forth above and any similar legend placed on any share
   certificate issued upon the transfer of any of the Summit Shares will be
   removed by delivery of substitute certificates without such legend if the
   undersigned, or any person who acquired, directly or indirectly, such Summit
   Shares, shall have delivered to Summit a copy of a letter from the staff of
   the SEC, or a written opinion of counsel acceptable to Summit, to the effect
   that the restrictions on sale, transfer or other disposition referred to in
   this letter are no longer necessary under the Act or otherwise in order to
   effect such sale, transfer or other disposition pursuant to law.


   
                                      D-2-2

           E. Summit agrees, by accepting this letter, (a) that for a period of
   two years after the Effective Time (or such shorter period as may be
   permitted by amendments to Rule 145) and thereafter until three months after
   I have ceased to be an affiliate of Summit and so long as Summit has equity
   securities registered pursuant to Section 12 of the Securities Exchange Act
   of 1934, as amended, Summit will make available with respect to itself
   "adequate current public information" as defined in paragraph (c) of Rule 144
   of the Rules and Regulations under the Act.

           I have carefully read this letter and, to the extent I felt
   necessary, discussed with my counsel the requirements of this letter and its
   impact upon the ability to dispose of the NSS Shares and the Summit Shares.


   Accepted this      day of      , 199__         Very truly yours,
   by Summit Bancorp.

                         FORM OF OPINION OF NSS COUNSEL
                            PURSUANT TO SECTION 7.05




   Summit Bancorp.
   301 Carnegie Center
   Princeton, New Jersey 08543-2066

   Gentlemen:

   This opinion is rendered to you pursuant to Section 7.05 of the
   Reorganization Agreement, dated June__, 1998 (the "Reorganization
   Agreement"), between NSS Bancorp, Inc. ("NSS" or the "Company") and Summit
   Bancorp. ("Summit"), which Reorganization Agreement provides, among other
   things, for the reorganization (the "Reorganization") of NSS with and into
   Summit and the issuance, in accordance with the Exchange Ratio provided for
   in the Reorganization Agreement, of whole shares of the Common Stock, par
   value $ .80 per share, of Summit (the "Summit Common Stock") and cash in lieu
   of fractional shares of Summit Common Stock in exchange for outstanding
   shares of the Common Stock, $.01 par value, of NSS (the "NSS Common Stock").
   In consideration of the Reorganization Agreement, NSS and Summit entered into
   a Stock Option Agreement dated June __, 1998 pursuant to which, among other
   things, NSS granted Summit a stock option with respect to shares of NSS
   Common Stock (the "Option Agreement").

   Capitalized terms used but not defined herein shall have the same meanings
   herein as ascribed to them in the Reorganization Agreement.

   We have acted as counsel to the Company in connection with the preparation,
   authorization, execution and delivery of the Reorganization Agreement and the
   Option Agreement and the consummation of the transactions contemplated by the
   Reorganization Agreement, including the preparation of the registration
   statement, as amended (the "Registration Statement"), under the Securities
   Act of 1933, as amended (the "Securities Act"), on Form S-4 of Summit (No.
   333- _______), and the proxy statement of NSS included in the Registration
   Statement (the "NSS Proxy Statement").

   In so acting, we have made inquiries of certain of the officers and
   representatives of the Company and its subsidiaries with respect to various
   matters contained in the Reorganization Agreement, the Option Agreement and
   the Registration Statement, and have examined and relied upon originals,
   certified or photostatic or facsimile copies of the Reorganization Agreement,
   the Option Agreement and such corporate records, agreements, documents and
   other instruments, and such certificates or the comparable documents of
   public officials and of such directors, officers and representatives of the
   Company and its subsidiaries as we have deemed relevant and necessary as a
   basis for the opinions hereinafter set forth.

   In such examination, we have assumed, without independent verification, the
   genuineness and authenticity of all signatures, the authenticity of all
   documents submitted to us as originals, the legal capacity of all natural
   persons and the conformity to original documents of documents submitted to us
   as certified or facsimile or photostatic copies and the authenticity of the
   originals of facsimile or photostatic copies. As to all questions of fact
   material to this opinion that have not been independently established, we
   have relied upon certificates or comparable documents of

   
                                       E-1

<PAGE>
   officers and representatives of the Company and upon the representations and
   warranties of the Company contained in the Reorganization Agreement. We have
   also assumed, without independent verification, the due authorization,
   execution, and delivery (other than the due authorization, execution and
   delivery by the Company) of all documents, the due authorization, execution
   and delivery of which are prerequisites to the effectiveness of such
   documents, and that such documents constitute legal, valid and binding
   obligations of the parties thereto (other than the Company).

   Based on the foregoing, and subject to the qualifications stated herein, we
   are of the opinion that:

   1. The Company has been duly organized and is validly existing as a
   corporation in good standing under the laws of the State of Connecticut and
   has all requisite corporate power and authority to own, lease and operate its
   properties and to carry on its business as now being conducted, as described
   in the Registration Statement.

   2. The Company is duly qualified to transact business as a foreign
   corporation and is in good standing in each jurisdiction where the failure to
   be so qualified cannot be cured and such failure would have a material
   adverse effect on the business, operations or financial condition of the
   Company and its subsidiaries taken as a whole.

   3. The Company is registered as a bank holding company under the Bank Holding
   Company Act of 1956, as amended.

   4. The authorized capital stock of NSS consists of xx,xxx,xxx shares of
   Common Stock, each of $.01 par value, and x,xxx,xxx shares of Preferred
   Stock, $.01 par value, and as of the date of the Reorganization Agreement
   xx,xxx,xxx shares of NSS Common Stock and ____ shares of NSS Preferred Stock
   were issued and outstanding, ________ shares of NSS Common Stock were held in
   the treasury of NSS, _______ shares of NSS Preferred Stock were reserved for
   issuance under the NSS Bancorp, Inc. Shareholder Rights Plan and ________
   shares of NSS Common Stock were reserved for issuance in connection with the
   NSS Stock Plans. All of the outstanding shares of capital stock of the
   Company are duly authorized, validly issued, and non-assessable, with no
   personal liability attaching to the ownership thereof, except as the owners
   thereof may be liable by reason of their own conduct or acts or under general
   equity principles, and have not been issued in violation of any preemptive
   rights. Since the date of the Reorganization Agreement, to the best of our
   knowledge, no Equity Securities of NSS have been issued except for the stock
   option granted to Summit in the Option Agreement and the NSS Common Stock
   reserved for issuance as of such date which may have been issued in
   connection with the NSS Stock Plans. Except as set forth above in this
   paragraph 4 and except for the Option Agreement, director and employee stock
   options outstanding under the NSS Stock Plans, NSS Common Stock issuable in
   connection with the NSS Stock Plans, and NSS Preferred Stock issuable under
   the NSS Shareholder Rights Plan, to the best of our knowledge, there are no
   other Equity Securities of NSS outstanding, in existence, the subject of an
   agreement or reserved for issuance.

   5. NSS Bank ("Bank") has been duly incorporated and is validly existing as a
   capital stock savings bank in good standing under the laws of the State of
   Connecticut and has all requisite corporate power and authority to own, lease
   and operate its properties and to carry on its businesses as now being
   conducted, as described in the Registration Statement. Each other subsidiary
   of the Company has been duly incorporated and is validly existing as a
   corporation in good standing under the laws of its jurisdiction of
   organization and has all requisite corporate power and authority to own,
   lease and operate its properties and to carry on its business as now being
   conducted, as described in the Registration Statement.

   
                                       E-2

   6. Bank is an insured depository institution under the Federal Deposit
   Insurance Act, as amended.

   7. All the outstanding capital stock of Bank and each subsidiary of the
   Company has been duly authorized and validly issued and is fully paid and
   non-assessable, with no personal liability attached to the ownership thereof,
   except as the owners thereof may be liable by reason of their own conduct or
   acts or under general equity principle, has not been issued in violation of
   any preemptive rights, and, as of the date hereof, to the best of our
   knowledge, no options covering capital stock of any subsidiary of the
   Company, warrants to purchase or contracts to issue capital stock of any
   subsidiary of the Company, or any other contracts, rights (including
   preemptive rights), commitments or convertible securities entitling anyone to
   acquire from the Company or any subsidiary of the Company or obligating any
   of them to issue any capital stock, or securities convertible into or
   exchangeable for any shares of capital stock thereof, are outstanding, in
   existence, or the subject of an agreement. The Company owns all the capital
   stock of Bank and each subsidiary of the Company free and clear of any
   perfected security interest and, to the best of our knowledge, any other
   security interest, lien, claim, limitation on voting rights, option, or other
   encumbrance.

   8. To the best of our knowledge, there are no outstanding contractual
   obligations of the Company or any subsidiary to repurchase, redeem, or
   otherwise acquire any outstanding shares of capital stock or other ownership
   interests of any subsidiary of the Company or to provide funds or to make any
   investment (in the form of a loan, capital contribution or otherwise), in any
   subsidiary or any other entity.

   9. The Company has the corporate power and authority to enter into the
   Reorganization Agreement and the Option Agreement and to carry out the
   transactions contemplated thereby; the Reorganization Agreement and the
   Option Agreement have been validly authorized, executed and delivered by the
   Company; the consummation of the transactions contemplated by the
   Reorganization Agreement, including the Reorganization, and the Option
   Agreement have each been duly authorized by all necessary corporate action on
   the part of the Company and its shareholders and (assuming the due
   authorization, execution and delivery thereof by Summit) the Reorganization
   Agreement and the Option Agreement each constitute a valid and binding
   agreement of the Company.

   10. The execution and delivery of the Reorganization Agreement and the Option
   Agreement and the performance thereof by the Company and the consummation of
   the Reorganization did not and will not violate, fail to comply with,
   conflict with, give rise to rights under, result in the breach of, or
   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 rights,
   permits licenses, assets or properties material to the Company and its
   subsidiaries taken as a whole, or any of its subsidiaries, or upon any of the
   capital stock of the Company or any of its subsidiaries, or constitute an
   event that could, with the lapse of time, action or inaction by the Company
   or any of its subsidiaries or a third party, or the giving of notice and
   failure to cure, result in any of the foregoing, under any of the terms,
   conditions or provisions, as the case may be, of: (a) the Certificate of
   Incorporation, By-laws or Shareholder Rights Plan of the Company, (b) any
   Federal law of the United States of America or any law of the State of
   Connecticut, (c) to the best of our knowledge, any rule, ruling,
   determination, ordinance or regulation of or agreement with any governmental
   or regulatory authority, (d) to the best of our knowledge, any judgment,
   order, writ, award, injunction or decree of any court or governmental
   authority issued in any proceeding to which the Company or any of its
   subsidiaries is or was a

   
                                       E-3
<PAGE>
   party or by which the Company or any of its subsidiaries or any of their
   assets or properties are bound or committed, or (e) to the best of our
   knowledge, any material note, bond, mortgage, indenture, lease, policy of
   insurance or indemnity, license, contract, agreement or other instrument to
   which the Company or any of its subsidiaries is a party or by which it or any
   of its subsidiaries or any of their assets or properties are bound or
   committed, other than any such violations, conflicts, breaches, defaults or
   accelerations the consequences of which do not or will not, in the aggregate,
   have a material adverse effect on the business, operations or financial
   condition of the Company and its subsidiaries, taken as a whole, or enable
   any person to enjoin the transactions contemplated by the Reorganization
   Agreement. No consent, approval, waiver, license or authorization or other
   action by or filing with any Federal or Connecticut governmental authority is
   required in connection with the execution and delivery by the Company of the
   Reorganization Agreement or Option Agreement or the consummation by the
   Company of the transactions contemplated thereby, including the
   Reorganization, except for (i) the filing of an appropriate Certificate of
   Reorganization as provided in the Reorganization Agreement, (ii) such filings
   and other actions as may be required by Federal or state securities laws and
   the rules and regulations thereunder (to which we are not opining), and (iii)
   those already obtained.

   11. To the best of our knowledge, there is no litigation, proceeding or
   governmental investigation pending or overtly threatened against the Company
   that relates to any of the transactions contemplated by the Reorganization
   Agreement or is material to the financial condition of NSS and its
   subsidiaries, taken as a whole.

   12. To the best of our knowledge, there are no persons who may be deemed to
   be affiliates of the Company for purposes of Rule 145 under the Securities
   Act who may receive shares of Summit Common Stock in the Reorganization and
   who are not named in the opinion delivered to the Company pursuant to Section
   4.11 of the Reorganization Agreement.

   13. The NSS Proxy Statement (except for the financial statements and the
   notes thereto, the financial statement schedules and the other financial,
   statistical and accounting data included, incorporated by reference or deemed
   incorporated by reference in the NSS Proxy Statement, as to which we express
   no opinion), but only insofar as the Company and its business, the
   Reorganization Agreement and the transactions contemplated thereby, including
   the Reorganization, and the Option Agreements are described in the NSS Proxy
   Statement, complies as to form in all material respects with the requirements
   of the Securities Act and the rules and regulations thereunder and the
   documents incorporated by reference in the Registration Statement pursuant to
   Part I.C. of Form S-4 under the Securities Act (except for the financial
   statements and the notes thereto and the financial statement schedules and
   other financial, statistical and accounting data included, incorporated by
   reference or deemed incorporated by reference, as to which we express no
   opinion) when filed with the Securities and Exchange Commission complied as
   to form in all material respects with the Securities Exchange Act of 1934, as
   amended, and the applicable rules and regulations thereunder.

   We have participated in conferences with officers and other representatives
   of the Company and Summit, representatives of the independent public
   accountants for the Company and Summit and counsel for Summit, at which
   conferences the contents of the Registration Statement and the NSS Proxy
   Statement and related matters were discussed, and, although we have not
   independently verified and are not passing upon and assume no responsibility
   for the accuracy, completeness or fairness of the statements contained in the
   Registration Statement and the NSS Proxy Statement, no facts have come to our
   attention that lead us to believe that the Registration Statement, on the
   effective date thereof, insofar as the Company and its business, the
   Reorganization Agreement and the transactions contemplated thereby, including
   the

   
                                       E-4
<PAGE>
   Reorganization, and the Option Agreement are described therein, contained an
   untrue statement of a material fact or omitted to state a material fact
   required to be stated therein or necessary in order to make the statements
   contained therein, in light of the circumstances under which they were made,
   not misleading or that the NSS Proxy Statement, on the date thereof or on the
   date hereof, insofar as the Company and its business, the Reorganization
   Agreement and the transactions contemplated thereby, including the
   Reorganization, and the Option Agreement are described therein, contained or
   contains an untrue statement of a material fact or omitted or omits to state
   a material fact required to be stated therein or necessary in order to make
   the statements contained therein, in light of the circumstances under which
   they were made, not misleading (it being understood that we express no view
   with respect to the financial statements and related notes, the financial
   statement schedules and the other financial, statistical and accounting data
   included, incorporated by reference or deemed incorporated by reference in
   the Registration Statement or the NSS Proxy Statement).

   Please be advised that, where any statement is stated herein as being "to the
   best of our knowledge" the statement refers to actual knowledge (or knowledge
   based upon the above-referenced certificates) and conscious awareness of
   facts or other information of the primary lawyer group of this firm which was
   actively involved in the transactions contemplated in the Reorganization
   Agreement, in the preparation of the documents involved and this opinion
   letter. We have not independently verified the accuracy of such statement but
   intend to advise you that in the course of our representation as counsel to
   the Company and, in particular, our participation in the preparation,
   authorization, execution and delivery of the Reorganization Agreement and the
   Option Agreement and in the preparation of the Registration Statement and the
   NSS Proxy Statement, nothing has come to our attention that leads us to
   believe, and we do not believe, that the matter is other than as stated
   therein. In addition, please be advised that our opinion with respect to the
   valid and binding nature of the Reorganization Agreement and the Option
   Agreement is subject to applicable bankruptcy, insolvency, reorganization,
   moratorium, fraudulent conveyance, fraudulent transfer and other laws
   presently or hereafter in effect affecting the enforcement of creditors'
   rights and remedies generally or institutions the deposits of which are
   insured by the Federal Deposit Insurance Corporation (the "FDIC"), and the
   affiliates of such institutions, and by equitable principles limiting the
   right to obtain specific performance or other similar equitable relief
   (regardless of whether such enforceability is considered in a proceedings in
   equity or at law) the discretion of a court in ordering specific performance
   or other equitable remedies, and to general principles of equity (regardless
   of whether questioned in a proceeding at law or in equity).

   The opinions herein are limited to the Federal laws of the United States and
   the corporate and banking laws of the State of Connecticut and we express no
   opinion as to the effect on any matter covered by this opinion of the laws of
   any other jurisdiction.

   This opinion is being furnished to, and is solely for the benefit of, Summit
   and is not to be quoted, used, circulated, published or disseminated,
   otherwise referred to in any documents, filed with any governmental agency,
   entity or person, or relied upon by any agency, entity or person other than
   Summit, without our prior written consent.

                                Very truly yours,

                            OPINION OF SUMMIT COUNSEL
                            PURSUANT TO SECTION 8.05


   NSS Bancorp, Inc.
   48 Wall Street
   Norwalk, Connecticut 06852


   Gentlemen:

       This opinion is rendered to you pursuant to Section 8.05 of the
   Reorganization Agreement, dated June __, 1998, (the "Reorganization
   Agreement"), between NSS Bancorp, Inc. ("NSS") and Summit Bancorp. ("Summit"
   or the "Company"), which Reorganization Agreement provides, among other
   things, for the reorganization (the "Reorganization") of NSS with and into
   Summit and the issuance, in accordance with the Exchange Ratio provided for
   in the Reorganization Agreement, of whole shares of the Common Stock, par
   value $.80 per share, of Summit (the "Summit Common Stock") and cash lieu of
   fractional shares of Summit Common Stock in exchange for outstanding shares
   of the Common Stock, $.01 par value, of NSS (the "NSS Common Stock"). In
   consideration of the Reorganization Agreement, NSS and Summit entered into a
   Stock Option Agreement dated June __, 1998 pursuant to which, among other
   things, NSS granted Summit a stock option with respect to shares of NSS
   Common Stock (the "Option Agreement").

       Capitalized terms used but not defined herein shall have the same
   meanings herein as ascribed to them in the Reorganization Agreement. As used
   herein, it is intended that "material" be determined with reference to Summit
   and its subsidiaries considered as one enterprise.

       I am Executive Vice President, General Counsel and Secretary of the
   Company and have served as counsel to the Company and in connection with the
   preparation, authorization, execution and delivery of the Reorganization
   Agreement, the Option Agreement and the consummation of the transactions
   contemplated thereby, including the preparation of the registration
   statement, as amended, under the Securities Act of 1933, as amended (the
   "Securities Act"), on Form S-4 of Summit (No. 333-xxxx), and the prospectus
   of Summit included therein (the registration statement, together with the
   prospectus of Summit included therein, is referred to as the "Registration
   Statement").

       In so acting, I have made inquiries of certain of the officers and
   representatives of the Company and its subsidiaries with respect to various
   matters contained in the Reorganization Agreement, the Option Agreement and
   the Registration Statement, and have examined and relied upon originals,
   certified or photostatic or facsimile copies of the Reorganization Agreement,
   the Option Agreement and such corporate records, agreements, documents and
   other instruments, and such certificates or comparable documents of the
   public officials and of such directors, officers and representatives of the
   Company and its subsidiaries as I have deemed relevant and necessary as a
   basis for the opinions hereinafter set forth.

       In such examination I have assumed, without independent verification, the
   genuineness and authenticity of all signatures, the authenticity of all
   documents submitted to me as originals, the legal capacity of all natural
   persons and the conformity to original documents of documents

   
                                       F-1

<PAGE>
   submitted to me as certified or facsimile or photostatic copies and the
   authenticity of the originals of facsimile or photostatic copies. As to all
   questions of fact material to this opinion that have not been independently
   established, I have relied upon certificates or comparable documents of
   officers and representatives of the Company and upon the representations and
   warranties of the Company contained in the Reorganization Agreement. I have
   also assumed, without independent verification, the due authorization,
   execution and delivery (other than due authorization, execution and delivery
   by the Company) of all documents, the due authorization, execution and
   delivery of which are prerequisites to the effectiveness of such documents,
   and that such documents constitute legal, valid and binding obligations of
   the parties thereto (other than the Company).

        Based on the foregoing and subject to the qualifications stated herein,
   I am of the opinion that:

       1. Company has been duly incorporated and is validly existing as a
   corporation in good standing under the laws of the State of New Jersey and
   has all requisite corporate power and authority to own, lease and operate its
   properties and to carry on its business as now being conducted, as described
   in the Registration Statement.

       2. The Company is duly qualified to transact business as a foreign
   corporation and is in good standing in each jurisdiction where the failure to
   be so qualified cannot be cured and such failure would have a material
   adverse effect on the Company and its subsidiaries taken as a whole.

       3. The Company is duly registered as a bank holding company under the
   Bank Holding Company Act of 1956, as amended.

       4. The authorized capital stock of the Company consists of 6,000,000
   shares of Preferred Stock, without par value, and 390,000,000 shares of
   Common Stock, par value $.80 per share, and, as of May 31, 1998 xxx,xxx,xxx
   shares of Summit Common Stock were issued and outstanding and 1,500,000
   shares of Series R Preferred Stock were reserved for issuance pursuant to
   Summit's Shareholder Rights Plan. All of the outstanding shares of capital
   stock of the Company are duly authorized, validly issued, and non-assessable,
   with no personal liability attaching to the ownership thereof, except as the
   owners thereof may be liable by reason of their own conduct or acts or under
   general equity principles, and have not been issued in violation of any
   preemptive rights.

       5. Each of the bank subsidiaries of Summit has been duly incorporated and
   is validly existing as a bank in good standing under the laws of the state of
   its incorporation and has all requisite corporate power and authority to own,
   lease and operate its properties and to carry on its business as now being
   conducted, as described in the Registration Statement.

       6. Each of the bank subsidiaries of Summit is an insured depository
   institution under the Federal Deposit Insurance Act, as amended.

       7. All the issued and outstanding capital stock of each of the bank
   subsidiaries of Summit has been duly and validly issued and is fully paid and
   nonassessable and, to the best of my knowledge, the Company owns, directly or
   indirectly, all such capital stock, and other Equity Securities of each of
   Summit's bank subsidiaries. Such stock is owned free and clear of any
   perfected security interest and, to the best of my knowledge, any other
   security interest.

       8. The Company has the corporate power and authority to enter into the
Reorganization

   
                                       F-2
<PAGE>
   Agreement and the Option Agreement and to carry out the transactions
   contemplated thereby; the Reorganization Agreement and the Option Agreement
   have been validly authorized, executed and delivered by the Company; the
   consummation of the transactions contemplated by the Reorganization
   Agreement, including the Reorganization, and the Option Agreement have each
   been duly authorized by all necessary corporate action on the part of the
   Company and (assuming the due authorization, execution and delivery thereof
   by NSS) the Reorganization Agreement and the Option Agreement each constitute
   the valid and binding agreement of the Company. 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 the Reorganization 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, the
   Reorganization 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.

       9. The execution and delivery of the Reorganization Agreement and the
   Option Agreement and the performance thereof by the Company and the
   consummation of the Reorganization did not and will not violate, fail to
   comply with, conflict with, give rise to rights under, result in the breach
   of, or 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 the Company and
   its subsidiaries, taken as a whole, or upon any of the capital stock of the
   Company or constitute an event that could, with the lapse of time, action or
   inaction by the Company or a third party, or the giving of notice and failure
   to cure, result in any of the foregoing, under any of the terms, conditions
   or provisions, as the case may be, of: (a) the Restated Certificate of
   Incorporation, By-Laws or Shareholder Rights Plan of the Company (b) any
   Federal law of the United States of America or any law of the State of New
   Jersey or the Commonwealth of Pennsylvania, (c) to the best of my knowledge,
   any rule, ruling, determination, ordinance or regulation of or agreement with
   any governmental or regulatory authority, (d) to the best of my knowledge,
   any judgment, order, writ, award, injunction or decree of any court or
   governmental authority issued in any proceeding to which the Company is a
   party or by which the Company or any of their assets or properties are bound
   or committed, or (e) to the best of my knowledge, any material note, bond,
   mortgage, indenture, lease, policy of insurance or indemnity, license,
   contract, agreement or other instrument to which the Company is a party or by
   which either of them or any of their assets or properties are bound or
   committed, other than any such violations, conflicts, breaches, defaults or
   accelerations the consequences of which do not or will not, in the aggregate,
   have a material adverse effect on the Company and its subsidiaries, taken as
   a whole, or enable any person to enjoin the transactions contemplated by the
   Reorganization Agreement or the Option Agreement. No consent, approval,
   waiver, license or authorization or other action by or filing with any
   Federal or New Jersey or Pennsylvania governmental authority is required in
   connection with the execution and delivery by the Company of the
   Reorganization Agreement or Option Agreement or the consummation by the
   Company of the transactions contemplated thereby, including the
   Reorganization, except for (i) the filing of an appropriate Certificate of
   Reorganization as provided by the Reorganization Agreement, (ii) such filings
   and other actions as may be required by Federal or state securities laws and
   the rules and regulations thereunder, and (iii) those already obtained.

       10. The Summit Common Stock to be issued pursuant to the Reorganization
Agreement has

   
                                       F-3
<PAGE>
   been duly authorized for issuance pursuant to the Reorganization Agreement
   and, when issued and delivered by the Company pursuant to the Reorganization
   Agreement, will be validly issued, fully paid and nonassessable. The issuance
   of the Summit Common Stock under the Reorganization Agreement is not subject
   to any preemptive rights under the Company's Restated Certificate of
   Incorporation or By-Laws or, to the best of my knowledge, any agreement by
   which the Company is bound.

       11. The Registration Statement is effective under the Securities Act and,
   to the best of my knowledge, no stop order suspending the effectiveness of
   the Registration Statement has been issued under the Securities Act or
   proceedings therefor initiated or threatened by the Securities and Exchange
   Commission.

       12. The Registration Statement (except for the financial statements and
   the notes thereto, the financial statement schedules and the other financial,
   statistical and accounting data included, incorporated by reference or deemed
   incorporated by reference in the Registration Statement, as to which I
   express no opinion) but only insofar as the Company and its business and the
   Reorganization Agreement, the Option Agreement and the transactions
   contemplated thereby, including the Reorganization, are described therein,
   comply as to form in all material respects with the requirements of the
   Securities Act and the rules and regulations thereunder. The documents filed
   by Summit with the Securities and Exchange Commission (the "Commission") and
   incorporated by reference in the Registration Statement pursuant to Part I.B.
   of Form S-4 under the Securities Act (except for the financial statements and
   the notes thereto and the financial statement schedules and other financial,
   statistical and accounting data included, incorporated by reference or deemed
   incorporated by reference, as to which I express no opinion) when filed with
   the Commission complied as to form in all material respects with the
   Securities Exchange Act of 1934, as amended, and the rules and regulations
   thereunder.

       I or members of my staff have participated in conferences with officers
   and other representatives of the Company and NSS, representatives of the
   independent public accountants for the Company and NSS and counsel for NSS,
   at which conferences the contents of the Registration Statement and related
   matters were discussed, and, although I have not independently verified and
   am not passing upon and assume no responsibility for the accuracy,
   completeness or fairness of the statements contained in the Registration
   Statement, no facts have come to my attention (either directly or indirectly
   after inquiries directed to members of my staff) that lead me to believe that
   the Registration Statement, on the effective date thereof contained, or on
   the date hereof contains, insofar as the Company and its business and the
   Reorganization Agreement, the Option Agreement and the transactions
   contemplated thereby, including the Reorganization, are described therein, an
   untrue statement of a material fact or omitted to state a material fact
   required to be stated therein or necessary in order to make the statements
   contained therein, in light of the circumstances under which they were made,
   not misleading (it being understood that I express no view with respect to
   the financial statements and related notes, the financial statement schedules
   and the other financial, statistical and accounting data included,
   incorporated by reference or deemed incorporated by reference in the
   Registration Statement).

       Please be advised that, where any statement is stated herein as being "to
   the best of my knowledge," the statement refers to my actual knowledge (or
   knowledge based upon the above-referenced certificates) and my conscious
   awareness of facts or other information. I have not independently verified
   the accuracy of such statement but intend to advise you that in the course of
   my duties as Executive Vice President, General Counsel and Secretary of the
   Company and, in particular, my participation in the preparation,
   authorization, execution and delivery of the

   
                                       F-4
<PAGE>
   Reorganization Agreement and the Option Agreement and in the preparation
   (together with members of my staff) of the Registration Statement, nothing
   has come to my attention (with respect to the Registration Statement, either
   directly or indirectly after inquiries directed to my staff) that leads me to
   believe, and I do not believe, that the matter is other than as stated
   herein. In addition, please be advised that my opinion with respect to the
   valid and binding nature of the Reorganization Agreement and the Option
   Agreement is subject to applicable bankruptcy, insolvency, reorganization,
   moratorium, fraudulent conveyance, fraudulent transfer and other laws
   presently or hereafter in effect affecting the enforcement of creditors'
   rights and remedies generally or institutions the deposits of which are
   insured by the Federal Deposit Insurance Corporation, and the affiliates of
   such institutions, and by equitable principles limiting the right to obtain
   specific performance or other similar equitable relief (regardless of whether
   such enforceability is considered in a proceeding in equity or at law), the
   discretion of a court in ordering specific performance or other equitable
   remedies, and to general principles of equity (regardless of whether
   questioned in a proceeding at law or in equity).

       The opinions herein are limited to the Federal laws of the United States
   and the corporate and banking laws of the State of New Jersey and the
   Commonwealth of Pennsylvania, and I express no opinion as to the effect on
   any matter covered by this opinion of the laws of any other jurisdiction.

       This opinion is not to be quoted or otherwise referred to in any
   documents or filed with any governmental agency, entity or person or relied
   upon by any agency, entity or person other than the addressee, without my
   prior written consent.


                                            Very truly yours,

                                                               Execution Version

                    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

NSS Bancorp, Inc., a Connecticut corporation ("Issuer").

                                   WITNESSETH:

         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

         NOW,  THEREFORE,  in  consideration  of the  foregoing  and the  mutual

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

<PAGE>

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 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

the assets or deposits of Issuer or any Bank Subsidiary, (y) a purchase or other

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

                                       -2-
<PAGE>
1933,  as amended  (the  "Securities  Act"),  with respect to, a tender offer or
exchange  offer  to  purchase  any  shares  of  Common  Stock  such  that,  upon
consummation  of  such  offer,  such  person  would  own or  control  securities
representing  10% or more of the  aggregate  voting  power of Issuer or any Bank
Subsidiary);

                  (iv)  After any  person  other  than  Grantee  or any  Grantee
Subsidiary  has made or  disclosed  an intention to make a proposal to Issuer or
its  shareholders  to engage in an  Acquisition  Transaction,  Issuer shall have
breached any covenant or obligation  contained in the  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

                                       -3-
<PAGE>

such right to exercise shall not have been consummated  prior to exercise of the
Option, pursuant to the statement of such right in the written notice exercising
the Option as provided in clause 2(e)(iii) above.

         (f) At the closing referred to in Section 2(e), Grantee shall surrender
this Agreement  (and the Option granted  hereby) to Issuer and pay to Issuer the
Aggregate Option Price (as defined in this Section 2(f) below) for the shares of
Common Stock  purchased  pursuant to the  exercise of the Option in  immediately
available  funds  by wire  transfer  to a bank  account  designated  by  Issuer;
provided,  however,  that failure or refusal of Issuer to designate  such a bank
account shall not preclude Grantee from exercising the Option. "Aggregate Option
Price" means the amount  obtained by  subtracting  (b) from (a) where (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 Issuer's Common
Stock on the date the Option is granted and this Agreement  signed,  but instead
to provide  for a  procedure  which (i) aligns  Grantee's  right to receive  the
Breakup Fee with its right to  exercise  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  Granee's  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,  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.  ss.18a and regulations  promulgated
thereunder and (y) in the event,  under the Bank Holding Company Act of 1956, as
amended (the "BHC Act"),  or the Change in Bank Control Act of 1978, as amended,
or any state  banking law,  prior  approval of or notice to the Federal  Reserve
Board or to any other Governmental  Authority is necessary before the Option may
be exercised, cooperating with Grantee in preparing such applications or notices
and  providing  such  information  to the Federal  Reserve  Board and each other
Governmental  Authority  as they may  require)  in order to  permit  Grantee  to
exercise  the Option and Issuer duly and  effectively  to issue shares of Common
Stock pursuant  hereto;  and (iv) to take all action  provided herein to protect
the rights of Grantee against dilution.

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

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

         (a)  Subject  to the last  sentence  of  Section 1, in the event of any
change in the Common  Stock by reason of stock  dividends,  split-ups,  mergers,
recapitalizations,  combinations, subdivisions, conversions, exchanges of shares
or the like,  the type and  number of shares of Common  Stock  purchasable  upon
exercise hereof shall be  appropriately  adjusted and proper  provision shall be
made so that, in the event that any additional  shares of Common Stock are to be
issued or otherwise to become  outstanding as a result of any such change (other
than  pursuant  to an exercise  of the  Option),  the number of shares of Common
Stock that remain  subject to the Option shall be increased so that,  after such
issuance and together with shares of Common Stock previously  issued pursuant to
the  exercise  of the Option  (as  adjusted  on account of any of the  foregoing
changes in the Common Stock),  it equals, 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.

                                       -5-
<PAGE>

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

         SECTION 6.        Registration Rights.

         (a) Demand  Registration  Rights.  After the  occurrence  of a Purchase
Event that occurs prior to an Exercise  Termination Event,  Issuer shall, at the
request of  Grantee  (whether  on its own behalf or on behalf of any  subsequent
holder  of  the  Option  (or  part  thereof)  delivered  prior  to  an  Exercise
Termination  Event or at the  request of a holder of any of the shares of Common
Stock  issued  pursuant  hereto)  delivered  no later  than 12  months  after an
Exercise  Termination  Event,   promptly  prepare,   file  and  keep  current  a
registration  statement  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

                                       -6-
<PAGE>

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

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

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

         (e)  Miscellaneous  Reporting.  Issuer shall comply with all  reporting
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) 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

                                       -8-
<PAGE>

substantial part, Grantee or the Owner, as appropriate, may revoke its notice of
repurchase  of the  Option  or the  Option  Shares  either  in  whole or in part
whereupon,  in the case of a  revocation  in part,  Issuer  shall  promptly  (i)
deliver to Grantee and/or the Owner, as appropriate,  that portion of the Option
Purchase  Price  or  the  Option  Share  Repurchase  Price  that  Issuer  is not
prohibited  from  delivering  after taking into account any such  revocation and
(ii) deliver, as appropriate,  either (A) to Grantee, a new Agreement evidencing
the right of Grantee to purchase  that number of shares of Common Stock equal to
the  number  of  shares of Common  Stock  purchasable  immediately  prior to the
delivery of the notice of  repurchase  less the number of shares of Common Stock
covered  by the  portion  of the  Option  repurchased  or  (B) to the  Owner,  a
certificate  for  the  number  of  surrendered  Option  Shares  covered  by  the
revocation.  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, Issuer's  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.

                                       -9-
<PAGE>

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

         (d) The following terms have the meanings indicated:

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

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

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

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

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

                                      -10-
<PAGE>

         (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 Issuer's  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 Issuer's 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 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:

         "The  transfer of the option  represented  by this  assignment  and the
         related  option  agreement  is subject to resale  restrictions  arising
         under the Securities Act of 1933, as amended and to certain  provisions
         of  an  agreement  between  Summit  Bancorp.  and  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

                                      -11-
<PAGE>
         Issuer and will be  provided  to any  permitted  assignee of the Option
         without change upon receipt by Issuer of a written request therefor."

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

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

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

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

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

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

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

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

                                      -12-

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

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

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

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

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

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

         SECTION 25. Covenant Against Action Under Certificate of Incorporation.
The Grantor  covenants  that it shall not, and by approving  this  Agreement the
Board  of  Directors  of  Grantor  hereby  resolves,  represents,  warrants  and
covenants that it shall not,  following any exercise of the Option  provided for
in this  Agreement,  act under  authority  of Article  THIRTEENTH  of  Grantor's
Certificate of 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.

                                      -13-
