       PRELIMINARY COPY - SUBJECT TO COMPLETION, DATED APRIL 13, 1998

                        BASSWOOD FINANCIAL PARTNERS, L.P.
                                52 Forest Avenue
                            Paramus, New Jersey 07652

                                                 [DATE], 1998

Dear Fellow NSS Shareholder:

     The past few years  have  seen the  stock  market  perform  far above  most
people's expectations.  In the midst of this environment, the value of NSS stock
has also risen.  However,  we should not rely on the current  exuberance  of the
market  to  continue  forever.  As  owners  (together  with our  affiliates)  of
approximately  9.97% of the  outstanding  common  shares of NSS,  we are  deeply
concerned  about the performance of management and the future value of NSS stock
in the uncharted years leading up to the year 2000 and beyond.

     We believe that NSS shareholders are in a position to take advantage of the
spectacular merger activity in the banking industry over the past several years.
Now is the time to act!  This is an  excellent  opportunity  for NSS to actively
explore  the  possibilities  of  achieving  the sale of the  company in order to
maximize  shareholder  value.  There is no  assurance  that we will  continue to
experience the rapid pace of merger  activity we have seen in recent years.  Nor
is there any assurance  that the value of NSS stock will remain at or exceed its
current level if the opportunity to merge is missed.

     For these reasons, we are asking for your support for the election of three
independent  director nominees for the NSS board at the May 27th Annual Meeting.
We also are  soliciting in favor of a shareholder  proposal, which we understand
will be  included in NSS's  proxy  materials  for the Annual  Meeting, that,  if
adopted,  would request  management  to take the necessary  steps to achieve the
sale of the company on terms most favorable to shareholders. We believe that NSS
shareholders have an opportunity now to maximize,  as well as lock-in and secure
the recent  appreciation  of, the value of their NSS shares through such a sale.
We urge you to sign and return the  enclosed  WHITE  proxy card in the  envelope
provided.

                                  THE NOMINEES

     If elected,  our  proposed  nominees  would  constitute  three out of eight
directors  on the NSS  board.  Our  nominees  are  successful  businessmen  with
expertise in the financial  services industry who can provide guidance in a time
of rapid  evolution of the banking  industry.  You should also know that Messrs.
Schoellkopf  and  Zoffinger  are truly  independent  nominees in that neither is
affiliated with Basswood  Financial  Partners or any of our  affiliates,  nor is
either  committed  to any  agenda  set by us.  We  believe  that  after you have
reviewed each of the nominee's qualifications, you will agree that they have the
knowledge  and  experience  to represent the interests of the company and of all
shareholders.

     Wolfgang Schoellkopf  currently is a principal of the Ramius Capital Group,
     L.L.C.,  an  investment  management  company.  Mr.  Schoellkopf  is  also a
     director of SLM Holding Corporation. From 1996 to 1997, Mr. Schoellkopf was
     a Vice Chairman of First Union National Bank in Newark,  New Jersey.  Prior
     thereto, he was a Vice Chairman of First Fidelity Bancorporation (which was
     merged into First Union Corporation in 1996).

     George R. Zoffinger  currently is the President and Chief Executive Officer
     of  Constellation  Capital Corp.,  an investment  management  company.  Mr.
     Zoffinger  is also a  director  of New  Jersey  Resources  Corporation  and
     Camelot Music Holding,  Inc. From 1995 to February 1998, Mr.  Zoffinger was
     the President and Chief  Executive  Officer of Value Property Trust, a real
     estate








     investment  trust (REIT) which was recently  sold to Wellsford  Properties.
     From 1993 to 1995, Mr.  Zoffinger was the Chairman of CoreStates New Jersey
     National  Bank.  Prior to that he was the  President  and  Chief  Executive
     Officer of Constellation Bancorp.

     Bennett Lindenbaum has been a money manager for Basswood Partners, L.P. and
     the Vice President of Basswood  Management,  Inc. since 1993. Both Basswood
     Partners and Basswood Management oversee and manage the investment of other
     affiliates  which  primarily  invest in banks,  bank holding  companies and
     thrift  institutions.  Prior to that, Mr. Lindenbaum was the Vice President
     of  Investments  for MGS  Corporation,  a company  involved  in propane gas
     distribution.

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

     If you wish to elect independent  nominees pledged to protect to secure the
interests of NSS and of all shareholders, and believe that NSS management should
seriously explore all options to maximize shareholder value,  including the sale
of the company,  please sign,  date and return the enclosed  WHITE proxy card in
the envelope provided. If you have already returned a proxy card to NSS, you may
revoke that vote by sending us a later-dated  WHITE proxy card. Only your latest
dated proxy counts.

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



To Our Fellow Shareholders of NSS Bancorp, Inc.:

     This proxy  statement (the "Proxy  Statement") and the enclosed WHITE proxy
card are being  furnished to holders of shares of common  stock,  par value $.01
per share (the "Shares"), of NSS Bancorp, Inc., a Connecticut corporation ("NSS"
or the "Company"),  of record on March 27, 1998 (the "Record Date"), by Basswood
Financial  Partners,  L.P. ( "Basswood") in connection with the  solicitation of
proxies by Basswood for use at the Annual Meeting of Shareholders of the Company
(the "Annual Meeting").  The Annual Meeting is currently  scheduled by NSS to be
held on Wednesday,  May 27, 1998, but may be adjourned or postponed.  The Annual
Meeting  will be held at  [LOCATION],  [ADDRESS],  at [TIME]  E.D.T.  This Proxy
Statement  and the  accompanying  WHITE  proxy  card  are  first  being  sent to
shareholders  on or about [DATE],  1998.  The mailing  address of NSS is 48 Wall
Street, P.O. Box 28, Norwalk, Connecticut 06852.

     Basswood is seeking your proxies in support of:

     o     the election of three  independent  nominees (the  "Nominees") to the
           Board of Directors (the "Board") of NSS; and

     o     the adoption of a shareholder  proposal, which we understand  will be
           included  in NSS's  proxy  materials  for the  Annual  Meeting,  that
           requests the Board to immediately take the necessary steps to achieve
           a sale,  merger or other  acquisition  of the  Company  on terms most
           favorable to shareholders (the "Shareholder Proposal").

     We believe that a Board that  includes the Nominees  will better  represent
the interests of the Company and of all the Company's  shareholders than a Board
composed entirely of incumbents  nominated by the Company's existing management.
The Nominees are  independent of the NSS management  and, we believe,  should be
able to bring new ideas and insights to the NSS management  and Board.  Morever,
Messrs. Schoellkopf and Zoffinger are truly independent nominees in that neither
is affiliated with Basswood or any of our affiliates, nor is either committed to
any agenda set by us. The Nominees are successful  businessmen with expertise in
the financial  services  industry who, we believe,  can provide valuable insight
and guidance in a time of rapid evolution of the banking industry. Additionally,
the Nominees have indicated their opposition









to  programs which  serve to entrench management or adversely affect shareholder
value  and their openness  to steps, such as seeking buyers for NSS, intended to
enhance shareholder value.

     We also believe that  shareholders  are in a position to take  advantage of
the spectacular  merger  activity in the banking  industry over the past several
years.  Now is the  time  to  act!  This  is a  perfect  time  for  the  Company
legitimately to explore the  possibilities  of achieving the sale of the Company
in order to  maximize  shareholder  value.  There is no  assurance  that we will
continue to experience the rapid pace of merger  activity we have seen in recent
years.  Nor is there any assurance that the value of NSS stock will remain at or
exceed its current level if the opportunity to merge is missed. We have included
a space for adopting the Shareholder  Proposal on our proxy card in the interest
of simplifying the proxy process for the shareholders of NSS.

     We have  also  included  a  space  for  ratifying  the  appointment  of the
independent  auditor  for the coming  year on our proxy card in the  interest of
simplifying  the proxy  process for the  shareholders  of NSS. This way, all you
need to do in order to vote for a full  slate of  directors  and  express a view
with respect to the Shareholder  Proposal and the  independent  auditor is sign,
date and return the  enclosed  WHITE proxy card.  You do not need to do anything
with the [COLOR] proxy card sent to you by the management of NSS.

     According to the  Company's  articles of  incorporation  and  by-laws,  NSS
currently has a total of eight directors  constituting the entire Board, divided
into three classes,  CLASS I consisting of three directors,  CLASS II consisting
of three directors,  and CLASS III consisting of two directors.  The articles of
incorporation  provide for each class of directors to be elected for  three-year
terms on a staggered  basis. At the Annual Meeting,  three Class I directors are
to be elected to serve until the 2001 annual meeting of  shareholders  and until
their respective  successors have been elected.  The three nominees for director
receiving the highest number of votes will be elected to the Board.

     Basswood  and its  affiliates  currently  beneficially  own 241,411  Shares
(approximately  9.97%  of  the  outstanding  Shares).   Information   concerning
Basswood,  its affiliates and the beneficial ownership of Shares is set forth in
"INFORMATION  CONCERNING  BASSWOOD AND RELATED  PERSONS" and  Appendices A and B
hereto.  The  principal  executive  offices of Basswood are located at 52 Forest

or her proxy prior to the Annual Meeting. ONLY THE LATEST DATED, PROPERLY SIGNED
PROXY CARD THAT YOU SEND IN WILL COUNT. MAKE SURE THAT CARD IS A WHITE CARD!


                            REASONS FOR SOLICITATION

INTRODUCTION

     As a significant  shareholder of NSS, Basswood is deeply concerned over the
way in which the  Company is being  managed by its  current  executives  and its
current Board.

     We are convinced  that,  with the addition of new directors,  the Company's
financial and operational performance can be improved,  shareholder value can be
enhanced  and  the  best  interests  of the  shareholders  can be  accorded  the
appropriate attention. The Nominees are successful businessmen with expertise in
the financial  services  industry who can provide valuable guidance in a time of
rapid  evolution  of the banking  industry.  They are  dedicated  to  supporting
measures   which  can  improve  the   Company's   performance   and  returns  to
shareholders.  Most  importantly,  the Nominees have expressed their openness to
seeking buyers for the Company.  Accordingly,  given the recent proliferation of
mergers and acquisitions in the banking industry and the ability of shareholders
to obtain substantial  premiums in such  transactions,  we are further convinced
that the time is now for the  Board to  seriously  explore  the  possibility  of
achieving  a sale,  merger or other  acquisition  of the  Company  on terms most
favorable to  shareholders.  Seize the day! We are  concerned  that the Board is
allowing a major  opportunity  to pass, and that at some time in the near future
current premium levels will no longer be available to NSS shareholders.

BACKGROUND OF SOLICITATION

     Since  Basswood and its affiliates  first acquired  Shares in January 1995,
representatives  of  Basswood  have met with  representatives  of NSS on several
occasions,  including meetings with Robert T. Judson, the President, and John L.
Segall, a current director of the Board.  Discussions  regarding areas of needed
improvement   relating  to  the  Company's   performance  focused  on  operating
efficiency  and core  profitability.  Furthermore,  the  Company's  current  and
prospective financial performance and results of operations were discussed,  and
the  Basswood  representatives  attempted  to  evaluate  whether  the  Company's
management  would pursue  opportunities  for the  acquisition  of the Company by
another  financial  institution or other purchaser if any such party indicated a
willingness to pursue such a transaction. As a result of such meetings, Basswood
formed a belief that management had no workable plan for maximizing  shareholder
value.


                                       -3-







     On November 13, 1997, Basswood Partners,  L.P. ("Basswood  Partners"),  the
general partner of Basswood,  wrote to the Board stating its  disappointment  in
the financial  results of the Company.  Basswood Partners also stated its belief
that larger financial  institutions  might have a serious interest in purchasing
the Company.  That belief was based, among other things, on the observation that
recently  announced  acquisitions  throughout the nation,  and  particularly  in
Connecticut,   such  as  the  Webster  Financial   Corporation/Eagle   Financial
Corporation  and  People's  Bank  of  Bridgeport/Norwich  Financial  Corporation
mergers, had provided,  or were to provide,  shareholders of target institutions
with  substantial  premiums.  Basswood  Partners also stated that it intended to
communicate with other  shareholders of the Company regarding methods to improve
the Company's future financial  performance and to enhance shareholder value. In
addition,  Basswood  Partners  requested  the right to inspect and copy  certain
records of the Company,  including  the record of  shareholders  of the Company.
However,  the Company  refused to provide  Basswood  Partners any access to such
records. Consequently, Basswood Partners was forced to take appropriate measures
to enforce its right as a shareholder  by filing an action to compel the Company
to grant it access to such records.  On February 6, 1998,  the Superior Court of
the State of Connecticut  issued an order granting  Basswood  Partners access to
such  records.  Subsequently,  the record of  shareholders  of the  Company  was
provided to  Basswood  Partners  and the  Company  agreed to provide to Basswood
Partners a non-objecting  beneficial  shareholder list (a NOBO list) if and when
obtained by the Company prior to the Annual Meeting.

     On or about March 13,  1995,  Basswood  Partners,  Matthew  Lindenbaum  and
Bennett  Lindenbaum filed a statement on Schedule 13D (as originally filed under
cover of a Form  F-11  with  the  Federal  Deposit  Insurance  Corporation,  the
"Schedule  13D")  with  the  Commission  disclosing  the  extent  of such  their
beneficial  ownership of outstanding  Shares. The Schedule 13D was amended on or
about January 18, 1996, May 13, 1996 and November 14, 1997 to reflect changes in
such  beneficial  ownership.  The Schedule 13D was amended on November 14, 1997,
January 5, 1998,  February  10,  1998 and  February  24,  1998 to  disclose  the
developments  described  above. On April 13, 1998, the Schedule 13D was amended,
indicating that Basswood may solicit proxies from other  shareholders for either
the  election of the Nominees or the  adoption of the  Shareholder Proposal,  or
both.

     On April  13,  1998, Basswood  sent a letter,  dated  April 9, 1998, to NSS
nominating Bennett Lindenbaum,  Wolfgang Schoellkopf and George R. Zoffinger for
election as  directors.  As management of NSS has not seen fit to include any of
the Nominees in their proposed slate for election,  we determined to propose our
own slate and to proceed with the  solicitation  of proxies in favor of election
of the Nominees.

REASONS

     We believe that a Board that  includes the Nominees  will better  represent
the interests of the Company and of all the Company's  shareholders than a Board
composed entirely of incumbents  nominated by the Company's existing management.
The Nominees are successful businessmen with expertise in the financial services
industry who, we believe, can provide valuable insight and guidance in a time of
rapid evolution of the banking industry. See "NOMINEES". They are independent of
the NSS management and should be able to bring new ideas and insights to the NSS
management  and Board.  Morever,  Messrs.  Schoellkopf  and  Zoffinger are truly
independent  nominees in that neither is affiliated  with Basswood or any of our
affiliates,  nor is either  committed to any agenda set by us. The Nominees have
indicated  their  opposition to programs  which serve to entrench  management or
adversely affect shareholder value and their commitment to explore all strategic
alternatives  for the  Company to enhance  shareholder  value,  including  their
openness  to seeking  buyers for NSS.  For these  reasons,  we believe  that the
election of the Nominees

                                       -4-







could enhance the Company's financial and operational performance and ability to
provide greater value for shareholders.

     We also believe that  shareholders  are in a position to take  advantage of
the spectacular  merger  activity in the banking  industry over the past several
years.  Now is the  time to act!  This is an  attractive  time  for the  Company
legitimately to explore the  possibilities  of achieving the sale of the Company
in order to  maximize  shareholder  value.  There is no  assurance  that we will
continue to experience the rapid pace of merger  activity we have seen in recent
years.  Nor is there any assurance that the value of NSS stock will remain at or
exceed its current level if the opportunity to merge is missed. This is an ideal
opportunity  for  shareholders  to  maximize,  as well as lock-in and secure the
recent  appreciation  of, the value of their NSS  Shares.  See "THE  SHAREHOLDER
PROPOSAL".


                                  THE NOMINEES

alternatives  for the Company to enhance  shareholder  value.  Morever,  Messrs.
Schoellkopf  and  Zoffinger  are truly  independent  nominees in that neither is
affiliated  with Basswood or any of our affiliates,  nor is either  committed to
any agenda set by us.

or other affiliate of the Company and none of the Nominees holds any position or
office with the Company,  has any family relationship with any executive officer
or  director of the  Company or each  other,  or has been  involved in any legal
proceedings  of the type  required to be disclosed by the rules  governing  this
solicitation.

     EACH OF THE NOMINEES HAS  CONSENTED TO SERVE AS DIRECTOR AND HAS PLEDGED TO
REPRESENT THE INTERESTS OF THE COMPANY AND OF THE SHAREHOLDERS AS A WHOLE TO THE
EXTENT THE LAW ALLOWS. MESSRS. SCHOELLKOPF AND ZOFFINGER WILL EACH BE PAID A FEE
OF APPROXIMATELY  $10,000, IN THE FORM OF SHARES, BY BASSWOOD AND ITS AFFILIATES
TO COMPENSATE THEM FOR THEIR TIME AND EFFORTS  REQUIRED AS NOMINEES FOR ELECTION
AS  DIRECTORS  OF  THE  COMPANY.  MESSRS.  SCHOELLKOPF  AND  ZOFFINGER  ARE  NOT
AFFILIATED  WITH BASSWOOD OR ANY OF OUR AFFILIATES,  NOR IS EITHER  COMMITTED TO
ANY AGENDA SET BY US.

     BY INCLUDING  THREE  NOMINEES,  WE HAVE ENABLED  SHAREHOLDERS TO VOTE FOR A
FULL SLATE OF DIRECTORS BY SIGNING,  DATING AND  RETURNING  ONLY THE WHITE PROXY
CARD  ENCLOSED  WITH THIS PROXY  STATEMENT.  BASSWOOD  URGES YOU TO SUPPORT  THE
ELECTION OF THE NOMINEES BY SIGNING,  DATING AND RETURNING THE WHITE PROXY CARD.
YOU SHOULD NOT RETURN THE [COLOR]  PROXY CARD PROVIDED BY MANAGEMENT IF YOU WISH
TO SUPPORT THE  NOMINEES.  IF YOU HAVE ALREADY SENT A [COLOR] PROXY TO THE BOARD
OF NSS,  YOU HAVE THE RIGHT TO REVOKE  THAT PROXY AND VOTE FOR THE  NOMINEES  BY
SIGNING, DATING AND MAILING A LATER DATED WHITE PROXY CARD.


                             THE SHAREHOLDER PROPOSAL

     Basswood is also  soliciting the  shareholders  in favor of the Shareholder
Proposal, which we understand will be included in NSS's proxy  materials for the
Annual Meeting.  We have included a space for adopting the Shareholder  Proposal
on our proxy card in the  interest  of  simplifying  the proxy  process  for the
shareholders.  We  recommend  that you vote FOR the  adoption  of the  following
resolution in addition to voting to elect the Nominees:

     "RESOLVED,  that the  shareholders  of NSS Bancorp,  Inc.  (the  "Company")
     hereby request that the Board of Directors  immediately  take the necessary
     steps to  achieve a sale,  merger or other  acquisition  of the  Company on
     terms most favorable to shareholders."

     We believe the  Company's  operating  performance  since its  conversion to
public ownership has been  unacceptable to investors and that any positive stock
performance has been due primarily to takeover

                                       -6-







speculation.  Moreover, the Company has not appropriately  evaluated and pursued
the possibility of a sale as a means of promoting shareholder value.

     In that light, we believe that at this time there are likely to be a number
of larger  institutions  that could have a serious  interest in  purchasing  the
Company.   Recent  transactions  throughout  the  nation,  and  specifically  in
Connecticut,  suggest  that through a sale,  the  Company's  shareholders  would
likely receive a substantial premium over the current market price. For example,
on March 31,  1998,  HUBCO Inc.  agreed to acquire  Dime  Financial  Corporation
("Dime"),  a  holding  company  for The  Dime  Savings  Bank of  Wallingford  in
Connecticut,  for approximately  $201 million in stock,  representing 2.56 times
Dime's tangible book value.  Although price and other terms actually  arrived at
in a transaction will depend on factors unique to the parties involved, applying
the ratio from the HUBCO Inc./Dime  transaction to NSS's tangible book value per
share of $22.44 (reported as of December 31, 1997) would imply a price of $57.45
per share for NSS common stock.

     BASSWOOD URGES YOU TO SUPPORT THE ADOPTION OF THE  SHAREHOLDER  PROPOSAL BY
SIGNING,  DATING AND RETURNING  THE WHITE PROXY CARD.  YOU SHOULD NOT RETURN THE
[COLOR] PROXY CARD  PROVIDED BY MANAGEMENT IF YOU WISH TO ADOPT THE  SHAREHOLDER
PROPOSAL AND ELECT THE NOMINEES. IF YOU HAVE ALREADY SENT A [COLOR] PROXY TO THE
BOARD OF NSS,  YOU HAVE THE RIGHT TO REVOKE THAT PROXY AND VOTE FOR THE ADOPTION
OF THE SHAREHOLDER PROPOSAL AND THE ELECTION OF THE NOMINEES BY SIGNING,  DATING
AND MAILING A LATER DATED WHITE PROXY CARD.

     We urge  shareholders not to rely solely on the Shareholder  Proposal,  for
the Board may elect to ignore it, holding it to be a mere precatory  resolution.
Therefore,  to provide increased assurance that the Board will carry into effect
the will of the shareholders as expressed by the Shareholder Proposal,  you need
to vote for the  election  of the  Nominees as well.  Please  note that  neither
Messrs.  Schoellkopf  or Zoffinger is committed to effect a sale of the Company.
They  are  committed  to  exploring  all  strategic   alternatives   to  enhance
shareholder value,  including a sale. Messrs.  Schoellkopf and Zoffinger are not
affiliated  with Basswood or any of our affiliates,  nor is either  committed to
any agenda set by us. However, Messrs.  Schoellkopf and Zoffinger have confirmed
to us that, if the  Shareholder  Proposal is adopted,  it is their  intention as
directors  to  effect  the  will of the  shareholders  and  put the  Shareholder
Proposal into operation.


                               INDEPENDENT AUDITOR

     According to the  Company's  Annual Report on Form 10-K for the fiscal year
ended  December 31, 1997 (the "1997 Form 10-K"),  Friedberg,  Smith & Co.,  P.C.
audited  the  consolidated  statements  of  financial  condition  of NSS and its
subsidiary  as of  December  31,  1997 and 1996,  and the  related  consolidated
statements  of earnings,  shareholders'  equity,  and cash flows for each of the
three years in the period ended December 31, 1997.  Based on publicly  available
information,  there  is no  basis  for us to  believe  otherwise  than  that NSS
management has appointed Friedberg, Smith & Co., P.C. as the independent auditor
for NSS for the ensuing year.


                         INFORMATION CONCERNING BASSWOOD
                               AND RELATED PERSONS

                                       -7-







Lindenbaum  are  the  sole  stockholders,   directors  and  officers.   Basswood
Management is the investment  manager of Basswood  International  Fund,  Inc., a
Cayman  Islands  exempted  company  ("Basswood   International")  the  principal
business of which is  investing  in  securities  for its own  account.  Basswood
Partners is the sole general partner of Whitewood  Financial  Partners,  L.P., a
Delaware limited partnership ("Whitewood"), and Basswood Supplemental Fund, L.P.
("Basswood  Supplemental"),  and a general partner of Jet I, L.P.  ("Jet"),  the

Garden State Trust, a New Jersey trust ("Garden  State" and,  collectively  with

     As of the date hereof,  the  Basswood  Companies  beneficially  own 241,411
Shares, or approximately 9.97% of the outstanding  Shares. In addition,  Matthew
Lindenbaum  owns 100 Shares in his own name. The Basswood  Companies and Matthew
Lindenbaum  intend to cause  proxies to be executed on their  behalf in favor of
election of the Nominees and the adoption of the Shareholder Proposal. They have
expressed no position on the  ratification of the appointment of the independent
auditor.

     Certain information  concerning related parties of Basswood who may solicit
proxies  from  other  shareholders  of NSS is set  forth in  Appendix  A hereto.
Information  concerning  purchases  and sales of Shares in the past two years by
the Basswood Companies, the Nominees and certain related parties is set forth in
Appendix B. None of such  persons has been  convicted  in a criminal  proceeding
(excluding  traffic  violations  or  similar  misdemeanors)  during the past ten
years.  None  of  such  persons  or any  associates  of  such  persons  has  any
arrangement  or  understanding  with  any  person  with  respect  to any  future
employment by NSS or with respect to any future transactions to which NSS or any
of its affiliates will or may be a party.


                           VOTING AND PROXY PROCEDURES

     The Board has established  March 27, 1998 as the Record Date for the Annual
Meeting.  We  understand  from the NSS 1997 Form  10-K that the total  number of
Shares  outstanding as of February 28, 1998 was 2,421,071  (the latest  publicly
available data). Only shareholders of record on the Record Date will be entitled
to vote at the Annual  Meeting.  If you sold Shares before the Record Date,  you
may not vote such  Shares.  If you were a  shareholder  of record on the  Record
Date,  you will retain your voting rights in connection  with the Annual Meeting
even if you sell or sold such Shares  after the Record  Date.  Based on publicly
available  information,  we believe  that the only  outstanding  class of voting
securities of the NSS is the Shares.  Each Share  outstanding on the Record Date
is entitled to one vote.  Shareholders are not currently  entitled to cumulative
voting for directors.

     According  to the NSS  by-laws,  the  presence in person or by proxy of the
holders of a majority  of the issued and  outstanding  stock of NSS  entitled to
vote at the Annual Meeting is necessary to constitute a quorum. Whether or not a
quorum is present in person or by proxy, the holders of a majority of the voting
power of the shares  present,  in person or by proxy,  have the power to adjourn
the Annual Meeting to a future date as may be agreed. Notice of such adjournment
must be given to shareholders  not present or represented by proxy at the Annual
Meeting. Additionally, whether or not a quorum is present in person or by proxy,
the holders of a majority of the voting power of the shares  present,  in person
or by proxy,  have the power to recess  the Annual  Meeting to a future  time to
resume no later than 48 hours  after the time of recess for the sole  purpose of
collecting  and soliciting  proxies.  Notice of such recess need not be given to
shareholders not present or represented by proxy at the Annual Meeting.  Section
33-712(a) of the Connecticut Business

                                       -8-







Corporation  Act provides that the directors to be elected at the Annual Meeting
are to be elected by a  plurality  of the votes cast by the shares  entitled  to
vote at the  Annual  Meeting.  Section  33-709(c)  of the  Connecticut  Business
Corporation  Act provides that any other action to be decided upon at the Annual
Meeting,  such as the adoption of the Shareholder  Proposal and the ratification
of the appointment of the independent  auditor, is approved if the votes cast in
favor  of the  action  exceed  the  votes  cast  in  opposition  of the  action.
Therefore, as long as the election of directors, the adoption of the Shareholder
Proposal and the ratification of the appointment of the independent  auditor are
voted upon as such,  valid and binding  action can be taken with respect to such
matters.  In that case,  the three  nominees for director  receiving the highest
number of votes will be elected to the Board. Furthermore, in order to adopt the
Shareholder  Proposal,  more  votes  would  have to be  voted  in  favor  of the
Shareholder  Proposal  than  against  it.  Accordingly,  abstentions  and broker
non-votes  will not have the effect of voting for or against the election of the
Nominees, any of the incumbent nominees, the independent auditor or the adoption
of the Shareholder Proposal.

     Shares of NSS  represented  by WHITE proxy cards which are properly  signed
and dated but on which no boxes are checked will,  unless such proxies have been
previously  revoked,  be voted FOR the election of the Nominees and the adoption
of the  Shareholder Proposal  and will  ABSTAIN  with respect to election of the
independent  auditors.  If any other  matter  properly  comes  before the Annual
Meeting or adjournments or postponements  thereof,  the persons named as proxies
on  the  enclosed  WHITE  proxy  card  (the  "Named   Proxies")  will  have  the
discretionary  authority to vote all proxies  with  respect to such matter.  The
Named Proxies are the agents of the shareholders from whom WHITE proxy cards are
received and are not the agents of, or affiliated with, Basswood.

     ONLY  HOLDERS  OF RECORD ON THE  RECORD  DATE ARE  ELIGIBLE  TO VOTE AT THE
ANNUAL MEETING.  PERSONS OWNING SHARES BENEFICIALLY (BUT NOT OF RECORD), SUCH AS
PERSONS WHOSE  OWNERSHIP OF SHARES IS THROUGH A BROKER,  BANK OR OTHER FINANCIAL
INSTITUTION,  SHOULD  CONTACT SUCH BROKER,  BANK OR  FINANCIAL  INSTITUTION  AND
INSTRUCT  SUCH PERSON TO EXECUTE THE WHITE PROXY CARD ON THEIR BEHALF OR TO HAVE
SUCH BROKER,  BANK OR FINANCIAL  INSTITUTION'S  NOMINEE (FOR EXAMPLE,  A CENTRAL
SECURITY DEPOSITORY SUCH AS CEDE & CO.) EXECUTE SUCH A PROXY CARD.

     In order for the proxy solicited  hereby to be voted at the Annual Meeting,
the  enclosed  WHITE  proxy card must be signed,  dated and  returned  to us c/o
Beacon  Hill  Partners,  the  proxy  solicitation  firm  retained  by us, in the
enclosed  envelope  (for which no postage  is  required  if mailed in the United
States)  in time to be voted at the  Annual  Meeting.  Any  holder of Shares may
revoke  his or her proxy at any time  prior to the  voting of such  proxy at the
Annual  Meeting by  delivering a written  revocation  of his or her proxy to the
Secretary  of NSS or  giving  a duly  executed  proxy  bearing  a later  date to
Basswood  or by  voting  in  person  at  the  Annual  Meeting.  Attendance  by a
shareholder  at the Annual  Meeting will not in itself  revoke his or her proxy.
ONLY YOUR LATEST DATED,  PROPERLY SIGNED PROXY WILL COUNT AT THE ANNUAL MEETING.
PLEASE MAKE CERTAIN THAT IT IS A WHITE CARD!


                               OWNERSHIP OF SHARES

     According to the Company's by-laws, each Share is entitled to one vote, and
the Shares are the only class of securities of NSS currently entitled to vote at
the  Annual  Meeting.   According  to  the  NSS  1997  Form  10-K,   there  were
approximately  688  holders  of record of Shares as of March 27,  1998 and there
were 2,241,071 Shares outstanding as of February 28, 1998.


                                       -9-







     Appendix C sets forth  information,  to the extent known by us, relating to
ownership of Shares by certain  beneficial owners of Shares and by management of
NSS.


                             SOLICITATION OF PROXIES

     Proxies will be solicited by mail, telephone,  telegraph, telex, telecopier
and  advertisement  and in person.  Solicitation  may be made by  Basswood,  the
Nominees and certain officers, personnel and other regular employees of Basswood
and its affiliates.  No such employees will receive additional  compensation for
such solicitation. See Appendix A hereto for a listing of such persons.

     BROKERS, CUSTODIANS,  NOMINEES AND FIDUCIARIES WILL BE REQUESTED TO FORWARD
THE SOLICITATION MATERIALS TO BENEFICIAL OWNERS OF THE SHARES. WE WILL REIMBURSE
BROKERS, CUSTODIANS,  NOMINEES AND FIDUCIARIES FOR THEIR REASONABLE EXPENSES FOR
SENDING THE SOLICITATION MATERIALS TO THE BENEFICIAL OWNERS OF SHARES.

     In addition, we have retained Beacon Hill Partners to assist and to provide
advisory  services in connection with this proxy  solicitation  for which Beacon
Hill Partners will be paid a fee of not more than $20,000 and will be reimbursed
for reasonable  out-of-pocket  expenses. We have also agreed to indemnify Beacon
Hill Partners  against certain  liabilities and expenses in connection with this
proxy solicitation.

     The  expenses  related  to this  proxy  solicitation  will be  borne by the
Basswood  Companies.  Basswood  believes that its efforts and this  solicitation
will  enhance the value of all  shareholder's  investments  in the  Company.  It
intends to seek reimbursement of the expenses related to this proxy solicitation
from NSS only to the extent  permitted by law.  Basswood does not intend to seek
shareholder  approval of such reimbursement  unless such approval is required by
law. Basswood  estimates that the total amount of expenses to be incurred by the
Basswood Companies in this proxy solicitation will be approximately $150,000. No
expenses have been incurred as of the date of this Proxy Statement.

     The information concerning NSS contained in this Proxy Statement (including
Appendix C hereto) has been taken from or is based upon documents and records on

verify,  or make any  representation  with  respect to the accuracy of, any such
information  or  statements.  The  proxy  statement  of  NSS  management,   when
