                                                          ________________, 1996
                                                                                
Dear Stockholder:

     On behalf of the Board of Directors, I want to extend to you a cordial
invitation to attend a Special Meeting of Stockholders (the "Special Meeting")
of the Bank of Tazewell County ("BTC").  The meeting will be held at _______
a.m., local time, on ___________________, 1996, at __________________.

     The purpose of the Special Meeting is to vote on a proposal to approve an
Agreement and Plan of Merger, dated as of August 28, 1995 (the "Merger
Agreement"), among BTC and National Bankshares, Inc. ("NBI"), pursuant to which
NBI Interim Bank ("NBI Interim"), a wholly owned subsidiary of NBI, will merge
(the "Merger") with and into BTC, together with an amendment and restatement of
BTC's Articles of Incorporation eliminating the preemptive rights of holders of
BTC common stock and conforming the BTC Articles of Incorporation to certain
provisions of the Articles of Incorporation of NBI Interim (the "BTC Charter
Amendment").  BTC stockholders will vote on the Merger Agreement, the related
Plan of Merger and the BTC Charter Amendment as one, unified proposal (the
"Proposal") and will not vote on each of the components separately.

     Upon consummation of the Merger each outstanding share of BTC common stock
will be converted into the right to receive one share of NBI common stock, with
cash in lieu of the issuance of any fractional share interest, in a transaction
that is generally tax-free for federal income tax purposes, all as more fully
discussed in the accompanying Prospectus/Proxy Statement.

     Consummation of the Merger is subject to certain conditions, including
approval of the Proposal by the affirmative vote of more than two-thirds of the
votes entitled to be cast at the Special Meeting by the holders of BTC common
stock and approval of the Merger by various regulatory agencies.

     The accompanying Notice of Special Meeting and Prospectus/Proxy Statement
contain information about the Merger.  I urge you to carefully review such
information, the information in NBI's 1994 Annual Report on Form 10-K, 1995
Annual Meeting Proxy Statement and 1995 Third Quarter Report on Form 10-Q,
copies of which are available as indicated in the accompanying Prospectus/Proxy
Statement under "AVAILABLE INFORMATION."

     The Board of Directors of BTC has unanimously adopted the Merger Agreement,
the related Plan of Merger and the BTC Charter Amendment and recommends that the
stockholders of BTC approve the Proposal.  Every stockholder's vote is
important.  A failure to vote, either by not returning the enclosed proxy or by
checking the ABSTAIN box thereon, will have the same effect as a vote against
approval of the Proposal.  Even if you plan to attend the Special Meeting in
person, please complete the enclosed proxy and mail it promptly in the enclosed
postage-paid, return addressed envelope.

                                              Yours very truly,


                                              R. E. Dodson
                                              President and

                   NOTICE OF SPECIAL MEETING OF STOCKHOLDERS
                         TO BE HELD ON _________, 1996
                   -----------------------------------------

     NOTICE IS HEREBY GIVEN that a Special Meeting of Stockholders (the "Special
Meeting") of the Bank of Tazewell County ("BTC") will be held at ___________,
local time, on _________________, 1996, for the following purposes, as more
fully set forth in the accompanying Prospectus/Proxy Statement:

     1.   To consider and vote upon a proposal to approve an Agreement and Plan
          of Merger, dated as of August 28, 1995 (the "Merger Agreement"), among
          BTC and National Bankshares, Inc. ("NBI"), pursuant to which (i) NBI
          Interim Bank, a wholly owned subsidiary of NBI, will merge (the
          "Merger") with and into BTC, and (ii) each outstanding share of BTC
          common stock (excluding any shares held by dissenting stockholders and
          certain shares held by NBI or BTC) will be converted into the right to
          receive one share of NBI common stock, with cash in lieu of the
          issuance of any fractional share interest, all on and subject to the
          terms and conditions contained therein, together with an amendment to
          and restatement of the BTC Articles of Incorporation eliminating the
          preemptive rights of holders of BTC common stock and conforming the
          BTC Articles of Incorporation to certain provisions of the Articles of
          Incorporation of NBI Interim (the "BTC Charter Amendment").

     2.   To transact such other business as may properly come before the
          Special Meeting or any adjournment or adjournments thereof.

     BTC stockholders will vote on the Merger Agreement, the related Plan of
Merger and the BTC Charter Amendment as one, unified proposal (the "Proposal")
and will not vote on each of the components separately.

     A copy of the Merger Agreement, including the related Plan of Merger that
is set forth in Annex 1 thereto, is set forth as Attachment A to the
Prospectus/Proxy Statement, and a copy of the BTC Charter Amendment is set forth
as Attachment B to the accompanying Prospectus/Proxy Statement.
    
     The Board of Directors of BTC has fixed __________, 1996, as the record
date for the determination of stockholders entitled to notice of and to vote at
the Special Meeting and, accordingly, only holders of record of BTC common stock
at the close of business on that date will be entitled to notice of and to vote
at the Special Meeting.     

     Approval of the Proposal by the holders of BTC common stock requires the
affirmative vote of more than two-thirds of the votes entitled to be cast at the
Special Meeting by the holders of BTC common stock.

     Pursuant to the Virginia Stock Corporation Act, holders of BTC common stock
have the right to dissent from the Merger and to demand payment of the fair
value of each such holder's shares of BTC common stock in the event the Merger
is consummated.  A holder of BTC common stock who wishes to assert such holder's
dissenters' rights must (i) deliver to BTC, before such vote is taken on the
Proposal, written notice of such holder's intent to demand payment for such
shares if the Merger is consummated, (ii) not vote such shares in favor of
approval of the Proposal, and (iii) comply with the further provisions of the
Virginia Stock Corporation Act in order to be entitled to receive in cash, if
the Merger is consummated, the fair value of such holder's BTC common stock.  A
vote against approval of the Proposal will not constitute written notice of an
intent to demand payment nor will a failure to vote against such approval
constitute a waiver of
<PAGE>
 
dissenters' rights.  A copy of the applicable provisions
of the Virginia Stock Corporation Act referred to above is set forth in
Attachment D to the accompanying Prospectus/Proxy Statement and a summary of
such provisions is set forth under "THE MERGER--Dissenters' Rights."

     The Board of Directors of BTC recommends that stockholders vote FOR
approval of the Proposal.

                              By Order of the Board of Directors of BTC


                              T. C. Bowen, Jr.
                              Chairman of the Board

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

STOCKHOLDERS ARE URGED TO DATE, SIGN AND RETURN PROMPTLY THE ENCLOSED PROXY IN
THE ACCOMPANYING ENVELOPE, WHICH REQUIRES NO POSTAGE IF MAILED IN THE UNITED
STATES.  IF A STOCKHOLDER RECEIVES MORE THAN ONE PROXY FOR ANY REASON, EACH
PROXY SHOULD BE COMPLETED AND RETURNED.  YOUR COOPERATION WILL BE APPRECIATED.
YOUR PROXY WILL BE VOTED WITH RESPECT TO THE MATTERS IDENTIFIED THEREON IN
ACCORDANCE WITH ANY SPECIFICATIONS ON THE PROXY.  IF NO SPECIFICATION IS MADE,
SUCH SHARES WILL BE VOTED IN FAVOR OF APPROVAL OF THE PROPOSAL.  A FAILURE TO
VOTE, EITHER BY NOT RETURNING THE ENCLOSED PROXY OR BY CHECKING THE ABSTAIN BOX
THEREON, WILL HAVE THE SAME EFFECT AS A VOTE AGAINST APPROVAL OF THE PROPOSAL.

          This Prospectus/Proxy Statement is being furnished by the Bank of
Tazewell County ("BTC"), a Virginia banking corporation, to the holders of BTC's

Directors for use at a Special Meeting of Stockholders of BTC to be held at

stockholders of BTC on or about __________, 1996.  The date of this

          The purpose of the Special Meeting is to consider and vote upon a

subsidiary of NBI, with and into BTC (the "Merger"), together with an amendment
and restatement of the BTC Articles of Incorporation to eliminate the preemptive
rights of holders of BTC Common Stock and conform the BTC Articles of
Incorporation to certain provisions of the Articles of Incorporation of NBI
Interim (the "BTC Charter Amendment").  See "SUMMARY," "THE MERGER" and
Attachment A and Attachment B to this Prospectus/Proxy Statement.  BTC
stockholders will vote on the Merger Agreement, the related Plan of Merger and
the BTC Charter Amendment as one, unified proposal (the "Proposal") and will not
vote on each of the components separately.

          Upon consummation of the Merger each outstanding share of BTC Common
Stock will be converted into the right to receive one share of NBI common stock,
par value $2.50 per share (the "Common Stock Exchange Ratio"), with cash in lieu
of the issuance of any fractional share interest.

          This Prospectus/Proxy Statement also constitutes a Prospectus of NBI
relating to the shares (the "NBI Common Shares") of NBI common stock that are
issuable to the holders of BTC Common Stock upon consummation of the Merger.
This Prospectus of NBI also relates to any NBI Common Shares that may be held by
any benefit or compensation plans of BTC following consummation of the Merger.
See "DESCRIPTION OF NBI CAPITAL STOCK," and "CERTAIN DIFFERENCES IN THE RIGHTS
OF BTC AND NBI STOCKHOLDERS."

          Based on the 1,888,209 shares of BTC Common Stock outstanding on the
Record Date (as hereinafter defined) and the Common Stock Exchange Ratio,
approximately 1,888,209 NBI Common Shares will be issuable upon consummation of
the Merger.

          The common stock of each of NBI and BTC is traded on a very limited
basis in the over-the-counter market and is not listed on any exchange or quoted
on the Nasdaq Stock Market ("Nasdaq").  Trading of NBI common stock and BTC
Common Stock each is presently reflected in the Over the Counter Electronic
Bulletin Board of the National Association of Securities Dealers, Inc. (the
"NASD").  On August 28, 1995, the last business day prior to public announcement

                                    SUMMARY

       The following is a brief summary of certain information relating to the
  Merger contained elsewhere in this Prospectus/Proxy Statement.  This summary
  is not intended to be a summary of all material information contained
  elsewhere in this Prospectus/Proxy Statement, including the Attachments
  hereto, and in the documents incorporated by reference in this
  Prospectus/Proxy Statement.  Copies of the Merger Agreement (including the
  related Plan of Merger) and the BTC Charter Amendment are set forth in
  Attachment A and Attachment B to this Prospectus/Proxy Statement and reference
  is made thereto for a complete description of the terms of the Merger and the
  BTC Charter Amendment.  Stockholders are urged to read carefully the entire
  Prospectus/Proxy Statement, including the Attachments.  As used in this
  Prospectus/Proxy Statement, the terms "NBI" and "BTC" refer to such
  corporations, respectively, and, where the context requires, such corporations
  and their respective subsidiaries.

  Parties to the Merger

       National Bankshares, Inc.
      
       NBI is a bank holding company organized under the laws of Virginia in
  1986 and registered under the Bank Holding Company Act of 1956, as amended
  (the "BHCA"). NBI currently conducts its operations through its sole wholly
  owned subsidiary, The National Bank of Blacksburg ("NBB"), which was
  originally chartered in 1891. NBB operates a full-service banking business
  from its headquarters in Blacksburg, Virginia, and its six area branch
  offices. NBB offers general retail and commercial banking products and
  services to individuals, businesses, local government units and institutional
  customers. NBB also conducts a general trust business in Blacksburg near its
  principal office. As of December 31, 1995, NBI had consolidated assets of
  approximately $203 million, consolidated net loans of approximately $123
  million, consolidated deposits of approximately $180 million and consolidated

  located at 100 South Main Street, Blacksburg, Virginia 24060, and its
  telephone number is (540) 552-2011. See "BUSINESS OF NBI."     

       Bank of Tazewell County
      
       BTC is a Virginia state-chartered commercial bank which traces its
  origins to 1889. BTC operates a full-service banking business from its
  headquarters office in Tazewell, Virginia, and its six branch offices. BTC is
  engaged in substantially all of the business operations customarily conducted
  by independent commercial banks in Virginia, including the acceptance of
  checking, savings and time deposits, and the making of commercial, real estate
  and installment loans. BTC also provides trust services. At December 31, 1995,
  BTC had approximately $178 million in assets, $40 million in net loans, $151
  million in deposits and $26 million in stockholders' equity. BTC's principal
  office is located at 309 East Main Street, Tazewell, Virginia 24651-1029 and
  its telephone number is (540) 988-5566. See "BUSINESS OF BTC."     

       NBI Interim Bank

       NBI Interim was organized by NBI solely for the purpose of facilitating
  the Merger.  Upon consummation of the Merger, NBI Interim will merge into BTC,
  the separate existence of NBI Interim will cease, and BTC will be the
  surviving corporation and will continue operations as a wholly owned
  subsidiary of NBI.

  Special Meeting; Record Date

       The Special Meeting will be held on ___________, 1996, at ______ a.m.,
  local time, at _________________________, for the purpose of BTC stockholders
  considering and voting upon a proposal to approve the Merger Agreement, the
  related Plan of Merger and the BTC Charter Amendment.  BTC stockholders will
  vote on the Merger Agreement, the related Plan of Merger and the BTC Charter
  Amendment as one, unified proposal (the "Proposal") and will not vote on each
  of the components separately.

                                       8
<PAGE>
 
    
       The Board of Directors of BTC has fixed ____________, 1996, as the
  record date for stockholders entitled to notice of and to vote at the Special
  Meeting (the "Record Date").  As of such date, there were 1,888,209 shares of
  BTC Common Stock outstanding and entitled to be voted at the Special Meeting.
  See "GENERAL INFORMATION."      

  The Merger; Common Stock Exchange Ratio

    
       Under the terms of the Merger Agreement, NBI Interim will merge with and
  into BTC, and BTC will continue its operations as a wholly owned subsidiary of
  NBI.  Upon consummation of the Merger (i) each outstanding share of BTC Common
  Stock (excluding any shares as to which holders have perfected their
  dissenters' rights ("Dissenting Shares") and excluding any shares held by NBI
  or BTC or their respective subsidiaries, other than in a fiduciary capacity or
  in satisfaction of a debt previously contracted ("NBI/BTC Held Shares")), will
  be converted into the right to receive one share of NBI common stock, with
  cash in lieu of the issuance of any fractional share interest.  The Common
  Stock Exchange Ratio takes into account the NBI Stock Split (as defined
  below).  See "THE MERGER--General" and "--NBI Stock Split," "DESCRIPTION OF
  NBI CAPITAL STOCK" and "CERTAIN DIFFERENCES IN THE RIGHTS OF BTC AND NBI
  STOCKHOLDERS."      

  Vote Required

       Approval of the Proposal requires the affirmative vote of more than two-
  thirds of the votes entitled to be cast by the holders of BTC Common Stock at
  the Special Meeting.
    
       The directors and executive officers of BTC (including certain of their
  related interests) beneficially owned, as of the Record Date, and are entitled
  to vote at the Special Meeting approximately 378,806 shares of BTC Common
  Stock, which is approximately 20.06 percent of the outstanding shares of BTC
  Common Stock entitled to be voted.  Directors and executive officers have
  indicated in informal discussions that they intend to vote their shares of BTC
  Common Stock in favor of the Proposal.  As of the Record Date, BTC, acting as
  fiduciary, custodian or agent, had sole or shared voting power over 81,350
  shares of BTC Common Stock (constituting approximately 4.3 percent of the
  outstanding shares).  All such shares will be voted in accordance with the
  governing agreements or instruments and applicable laws and regulations.  See
  "GENERAL INFORMATION--Record Date; Votes Required."      
 
       Every stockholder's vote is important.  A failure to vote, either by not
  returning the enclosed proxy or by checking the ABSTAIN box thereon, will have
  the same effect as a vote against approval of the Proposal.

  Merger Effective Date

       Subject to the conditions to the obligations of the parties to effect the
  Merger, the Merger will become effective at 11:59 p.m. (the "Merger Effective
  Date") on the date that the Virginia Commission issues a certificate of merger
  evidencing the effectiveness of the Merger.  Unless otherwise agreed by NBI
  and BTC, and subject to the conditions to the obligations of the parties to
  effect the Merger, the parties have agreed to use their reasonable efforts to
  cause the Merger Effective Date to occur as soon as practicable following the
  satisfaction of:  (i) approval of the Proposal by the requisite vote of the
  BTC stockholders; (ii) issuance of a certificate of effectiveness for the BTC
  Charter Amendment by the Virginia Commission, procurement of the charter of
  NBI Interim (the "Interim Approval") and procurement of the approval of the
  Merger by (a) the Federal Deposit Insurance Corporation (the "FDIC") under the
  Bank Merger Act of 1960 (the "FDIC Approval"), (b) the Virginia Bureau of
  Financial Institutions (the "BFI") pursuant to Virginia Code (S) 6.1-44 (the
  "State Bank Merger Approval"), (c) the Board of Governors of the Federal
  Reserve Board (the "Federal Reserve Board") under the BHCA (the "FRB
  Approval"), and (d) the BFI, to the extent necessary, under Chapter 13 of
  Title 6.1 of the Code of Virginia (the "State Holding Company Approval"), and
  expiration of any statutory waiting periods relating thereto (the Interim
  Approval, the FDIC Approval, the State Bank Merger Approval, the FRB Approval
  and the State Holding Company Approval are collectively referred to herein as
  the "Required Regulatory Approvals"); and (iii) procurement of all other
  regulatory consents and approvals and satisfaction of all other requirements
  prescribed by law which are necessary to consummate the Merger; provided,
  however, that no approval or consent in paragraph (ii) or (iii) above shall
  have imposed any condition or requirement which would materially adversely
  impact the economic or business benefits of the transactions contemplated by

                                       9
<PAGE>
    
  the Merger Agreement and the related Plan of Merger so as to render
  inadvisable the consummation of the Merger. Subject to the foregoing, it is
  currently anticipated that the Merger will be consummated in the second
  quarter of 1996. See "THE MERGER--Conditions to Consummation; Termination." 
     
  Recommendation of BTC's Board of Directors

       The Board of Directors of BTC has unanimously adopted the Proposal as
  being in the best interests of BTC and its stockholders and recommends
  approval of the Proposal by BTC's stockholders.
      
       The conclusions of the BTC Board of Directors are based upon a number of
  factors, including the fairness opinion of its financial adviser concerning
  the Common Stock Exchange Ratio, the expected increase in the market liquidity
  of a stockholder's investment and the tax-free nature of the Merger to the BTC
  stockholders.  The BTC Board of Directors also believes that the combined
  resources of BTC and NBI will provide a realistic alternative to larger
  financial institutions which are resulting from consolidation within the
  banking industry.  It is also anticipated that centralized management and
  certain economies of scale will eventually increase the efficiency and
  profitability of both institutions, including that certain departments of the
  respective banks, such as data processing, trust and risk management, may be
  centralized and consolidated at some time, although there are no specific
  plans at this time to do so.  Additionally, although NBI currently has no
  specific plans in this regard, it is expected that the Merger will allow NBB
  and BTC to consider utilizing technologies which would be cost prohibitive for
  either party separately.  See "THE MERGER--Background and Reasons--BTC."      

  Opinions of BTC's Financial Adviser

       Baxter, Fentriss & Company ("Baxter Fentriss") has advised BTC's Board of
  Directors that, in its opinion, the terms of the Merger are fair to the
  holders of BTC Common Stock from a financial point of view.  The full text of
  Baxter Fentriss' opinion, dated as of the date of this Prospectus/Proxy
  Statement is set forth in Attachment C to this Prospectus/Proxy Statement and
  should be read in its entirety by BTC stockholders.  For further information
  regarding the opinions of Baxter Fentriss and a discussion of the
  qualifications of Baxter Fentriss and the method of their selection, see "THE
  MERGER--Background of the Merger" and "--Opinions of BTC's Financial Adviser."

  Management and Operations of NBI and BTC after the Merger

       At the Merger Effective Date, BTC will become a wholly owned subsidiary
  of NBI, but will maintain its separate name, identity and operations.  No
  change in the Board of Directors or executive officers of BTC will result from
  the Merger.  It is also contemplated that BTC will maintain all of its current
  offices.

       After the Merger Effective Date, the Board of Directors of NBI will be
  comprised of nine persons, one of whom will be Mr. James G. Rakes, President
  of NBI and NBB, four of whom will be persons selected by BTC from among its
  current Board of Directors (the "BTC Board Representatives") and four of whom
  will be persons currently members of the Board of Directors of NBI.  No change
  in the executive officers of NBI will result from the Merger.
      
       The Board of BTC has selected T. C. Bowen, Jr., A. A. Crouse, R. E.
  Dodson and William T. Peery as the initial BTC Board Representatives.  NBI has
  agreed to take certain actions, including amendments to its Bylaws, in order
  to assure that certain actions affecting BTC will not be initiated by NBI
  without the consent of at least one of the BTC Board Representatives before
  January 1, 2001.  See "THE MERGER--Management and Operations of NBI and BTC
  after the Merger."      

  Interests of Certain Persons

       NBI has agreed that, for six years following the Merger Effective Date,
  NBI will cause BTC and any successor thereto or any subsidiary thereof, to
  indemnify any person who has rights to indemnification from BTC, to the same
  extent and on the same conditions as such person is entitled to
  indemnification pursuant to BTC's Articles of Incorporation as in effect on
  the date of the Merger Agreement, to the extent legally permitted to do so,
  with respect to matters occurring on or

                                       10
<PAGE>
 
  prior to the Merger Effective Date.  The adoption of the BTC Charter Amendment
  will not affect any person's right, if any, to such indemnification.  NBI has
  agreed to use its reasonable best efforts to provide coverage to the officers
  and directors of BTC under NBI policy or policies of directors and officers
  liability insurance on the same or substantially similar terms then in effect
  for the directors and officers of NBB, and BTC shall reimburse NBI for the
  additional premium incurred by NBI in connection with providing such coverage.
  See "THE MERGER-- Interests of Certain Persons."

  Certain Federal Income Tax Consequences

       KPMG Peat Marwick LLP ("KPMG"), NBI's independent auditors, has advised
  NBI and BTC that, in its opinion, no gain or loss will be recognized for
  federal income tax purposes by stockholders of BTC who receive in the Merger
  NBI Common Shares, other than in respect of cash received by holders of BTC
  Common Stock in lieu of fractional share interests.  The exchange of BTC
  Common Stock for cash pursuant to the exercise of dissenters' rights will be a
  taxable transaction.  See "THE MERGER--Certain Federal Income Tax
  Consequences."

       BECAUSE CERTAIN TAX CONSEQUENCES OF THE MERGER MAY VARY DEPENDING UPON
  THE PARTICULAR CIRCUMSTANCES OF EACH STOCKHOLDER, IT IS RECOMMENDED THAT BTC
  STOCKHOLDERS CONSULT THEIR TAX ADVISERS CONCERNING THE FEDERAL (AND ANY STATE
  AND LOCAL) TAX CONSEQUENCES OF THE MERGER IN THEIR PARTICULAR CIRCUMSTANCES.

  Business Pending Consummation

       BTC and NBI have agreed in the Merger Agreement not to take certain
  actions relating to their respective operations pending consummation of the
  Merger without the prior written consent of the other party, except as
  otherwise permitted by the Merger Agreement.  These actions include, without
  limitation:  (i) paying any dividends, other than common stock cash dividends
  consistent with past practice and in an amount not greater than the last
  previous cash dividend paid prior to execution of the Merger Agreement,
  subject to certain limited exceptions; (ii) redeeming or otherwise acquiring
  any shares of capital stock, or issuing any additional shares of capital stock
  or giving any person the right to acquire any such shares, or issuing any
  long-term debt; (iii) entering into any employment agreements with, increasing
  the rate of compensation of or paying any bonus to any director, officer or
  employee, except in accordance with plans or agreements existing and as in
  effect on the date of the Merger Agreement and previously disclosed; (iv)
  entering into or modifying any directors' or employees' benefit plans; (v)
  disposing of or granting an encumbrance against any material portion of assets
  or merging or consolidating with, or acquiring any substantial portion of the
  business or property of, any other entity; or (vi) taking any other action not
  in the ordinary course of business.  See "THE MERGER--Business Pending
  Consummation."

  Regulatory Approvals

       The Merger transaction is subject to the prior approval of the FDIC, the
  Federal Reserve Board, the BFI and the Virginia Commission, as required by
  applicable law.  Applications have been filed with each of such regulatory
  authorities for approval of the transaction.  There can be no assurance that
  the Required Regulatory Approvals will be obtained or as to the timing or
  conditions of such approvals.

  Conditions to Consummation; Termination

       Consummation of the Merger is subject, among other things, to:  (i)
  approval of the Proposal by the requisite vote of the stockholders of BTC;
  (ii) receipt of the Required Regulatory Approvals referred to above without
  any restrictions or conditions which would so materially adversely impact the
  economic or business benefits of the transactions contemplated by the Merger
  Agreement so as to render inadvisable the consummation of the Merger; (iii)
  there being in effect no order, decree or injunction of any court or
  governmental or regulatory authority prohibiting the Merger; (iv) the
  Registration Statement being effective and receipt of all state securities law
  approvals; (v) receipt by NBI and BTC of an opinion from KPMG to the effect
  that the acquisition of BTC Common Stock by NBI and the Merger generally
  constitutes a tax-free reorganization under Section 368 of the Internal
  Revenue Code; (vi) receipt by NBI and BTC of a letter, satisfactory to NBI and
  BTC, from KPMG that the Merger will qualify for pooling-of-interests
  accounting treatment; (vii) receipt by each party of an opinion from its
  financial adviser that the terms of the Merger are fair to its stockholders
  from a financial point of view;

                                       11
<PAGE>
 
  and (viii) receipt by each party of a letter from the other party's
  independent certified public accountant to the effect that it is not aware of
  any facts or circumstances relating to actions taken by such party or actions
  that such party has failed to take that might cause the Merger not to qualify
  for pooling-of-interests accounting treatment.

       The Merger Agreement may be terminated prior to the Merger Effective Date
  by mutual consent of the Boards of Directors of NBI and BTC.  The Merger
  Agreement may also be terminated by the Board of Directors of either NBI or
  BTC if (i) the Merger does not occur on or before June 30, 1996; (ii) certain
  conditions set forth in the Merger Agreement are not met; (iii) there is a
  breach by the other party of a representation, warranty, covenant or agreement
  in the Merger Agreement which has not been cured within a certain time period;
  or (iv) the Board of Directors of NBI recommends to NBI stockholders approval
  of a sale of all or substantially all of the assets of NBI or the merger or
  consolidation of NBI with and into another entity with the effect that NBI
  will not be the surviving corporation in such merger or consolidation.  See
  "THE MERGER--Conditions to Consummation; Termination."

  Expenses

       All expenses incurred by or on behalf of the parties in connection with
  the Merger Agreement and the transactions contemplated thereby will be borne
  by the party incurring the same, except (i) that printing expenses for this
  Prospectus/Proxy Statement will be shared equally by NBI and BTC and (ii) in
  the circumstances below.

       In the event that the Merger Agreement is terminated otherwise than on
  account of a breach by NBI or because NBI recommends to NBI stockholders
  approval of a sale of all or substantially all of the assets of NBI or the
  merger or consolidation of NBI with or into another entity with the effect
  that NBI will not be the surviving corporation in such merger or consolidation
  (see "THE MERGER--Conditions to Consummation; Termination"), the total
  documented out-of-pocket costs, expenses and fees incurred by BTC and NBI in
  connection with and arising out of the Merger and the other transactions
  contemplated by the Merger Agreement (including, without limitation, amounts
  paid or payable to investment bankers, to counsel and accountants and to
  governmental and regulatory agencies) shall be aggregated and each party shall
  be responsible for paying one-half of the same.

       To compensate NBI or BTC, as the case may be, for entering into the
  Merger Agreement, taking action to consummate the transactions contemplated
  thereunder and incurring the costs and expenses relating thereto, including,
  but not limited to, the forgoing of other opportunities and other damages
  which would be sustained but also would be difficult to ascertain, NBI or BTC,
  as the case may be, will pay the other party unconditionally and absolutely
  the sum of $2,500,000 as the other party's exclusive remedy if, prior to the
  termination of the Merger Agreement, certain events relating to another
  acquisition transaction occur.  See "THE MERGER--Expenses."

  Dissenters' Rights

       Holders of BTC Common Stock entitled to vote on approval of the Proposal
  have the right to dissent from the Merger and, upon consummation of the Merger
  and the satisfaction of certain specified procedures, to receive cash in
  respect of the fair value of each such holder's shares of BTC Common Stock in
  accordance with the applicable provisions of the Virginia Stock Corporation
  Act (the "Virginia Act").  The procedures to be followed by a dissenting
  stockholder are summarized under "THE MERGER--Dissenters' Rights," and a copy
  of the applicable provisions of the Virginia Act is set forth in Attachment D
  to this Prospectus/Proxy Statement.  Failure to follow such provisions
  precisely may result in loss of such dissenters' rights.

       In general, any dissenting stockholder who perfects such holder's
  statutory dissenters' rights to be paid in cash the fair value of such
  holder's BTC Common Stock will recognize gain or loss for federal income tax
  purposes upon receipt of such cash.  See "THE MERGER--Certain Federal Income
  Tax Consequences."

  BTC Charter Amendment

       As part of the Merger transaction, the BTC Board of Directors has
  recommended that its stockholders approve an amendment and restatement of
  BTC's Articles of Incorporation to, among other things, (i) eliminate the
  preemptive rights of holders of shares of BTC Common Stock; (ii) conform the
  Articles of Incorporation of BTC precisely to certain provisions of the
  Articles of Incorporation of NBI Interim relating to the limitation of
  liability and indemnification of BTC directors and officers and the number of
  directors constituting the Board of Directors of BTC; and (iii) eliminate
  existing provisions of BTC's Articles of Incorporation with respect to the
  issuance of shares of BTC Common Stock by the Board and repeal any other
  provisions which are contrary, inconsistent or similar to (ii) above.  The
  amendments are intended to facilitate the Merger transaction and integrate BTC
  into NBI's holding company structure.  See "THE MERGER--BTC Charter
  Amendment."
      
  NBI Stock Split      
      
       NBI will, prior to the Merger Effective Date, increase the number of
  shares of NBI common stock issued and outstanding by means of a stock split
  effected in the form of a stock dividend (the "NBI Stock Split") totaling
  190,768 shares of NBI common stock; provided, however, that NBI shall not be
  required to declare such NBI Stock Split until (i) approval of the Proposal
  by the requisite vote of BTC stockholders; (ii) issuance of a certificate of
  effectiveness for the BTC Charter Amendment by the Virginia Commission and
  receipt of the Required Regulatory Approvals and expiration of any statutory
  waiting periods relating thereto; and (iii) such time as BTC acknowledges in
  writing that all conditions to its obligations to consummate the Merger (and
  BTC's right to terminate the Merger Agreement) have been waived or satisfied.
  The Common Stock Exchange Ratio takes into account the NBI Stock Split.  See
  "THE MERGER--General" and "--NBI Stock Split."      

  Resale of NBI Common Shares

       The NBI Common Shares will be freely transferrable by the holders of such
  shares, except for those shares held by those holders who may be deemed to be
  "affiliates" (generally including directors, certain executive officers and
  certain large stockholders) of BTC or NBI under applicable federal securities
  laws.  See "RESALE OF NBI COMMON SHARES."  NBI has agreed that it will use its
  best efforts, after consummation of the Merger, to cause the NBI common stock,
  including, but not limited to, the NBI Common Shares to be issued to the
  holders of shares of BTC Common Stock in connection with consummation of the
  Merger, to be listed on Nasdaq.  The Nasdaq listing criteria require NBI to,
  among other things, satisfy certain minimum requirements with respect to its
  total assets, capital and surplus, the number of holders of record of NBI
  common stock, the number of shares of NBI common stock outstanding and its
  market value in the trading market for the common stock.  NBI believes that it
  currently meets the Nasdaq listing requirements; however, there can be no
  assurance whether or when the NBI common stock will be accepted for listing on
  Nasdaq nor of the effect that such listing, if accomplished, would have on the
  trading market for NBI's common stock.  See "THE MERGER--Market Prices."

(1) Pro forma NBI book value per common share adjusted for stock split has
    been computed giving effect to the NBI Stock Split of 0.11129 per share
    effected in the form of a stock dividend, to be declared and issued pro rata
    to holders of NBI common stock just prior to the Merger to facilitate the
    one-for-one Common Stock Exchange Ratio of NBI common stock for BTC Common
    Stock.     

(2) Pro forma combined book value per NBI common share amounts represent the
    sum of pro forma combined common stockholders' equity amounts, divided by
    pro forma combined period-end common shares outstanding.

(3) Equivalent pro forma book value per BTC common share amounts represent the
    pro forma combined book value per NBI common share amounts, multiplied by
    the Common Stock Exchange Ratio. The equivalent pro forma book value per 
    BTC common share of $12.46 at September 30, 1995 compared to BTC's
    historical book value per common share of $13.25 results in dilution of
    approximately 6%.

  (4) Pro forma NBI cash dividends declared per common share adjusted for stock
      split has been computed giving effect to the NBI Stock Split of 0.11129
      per share effected in the form of a stock dividend, to be declared and
      issued pro rata to holders of NBI common stock just prior to the Merger to
      facilitate the one-for-one Common Stock Exchange Ratio of NBI common stock
      for BTC Common Stock.     

  (5) Pro forma combined cash dividends declared per NBI common share amounts
      represent pro forma combined cash dividends declared on common stock
      outstanding, divided by pro forma combined average common shares
      outstanding.
      
  (6) Equivalent pro forma cash dividends declared per BTC common share amounts
      represent NBI historical dividends declared per common share, adjusted for
      the NBI Stock Split, multiplied by the Common Stock Exchange Ratio. The
      current annual dividend rate per share for NBI common stock, based on the
      dividend rates of $.30 per share paid on June 1, 1995 and $.33 per share
      paid on December 1, 1995, adjusted for the 0.11129 per share NBI Stock
      Split to be declared and issued just prior to the Merger, would be $.57.
      On an equivalent pro forma basis, such current annual NBI dividend per BTC
      common share would be $.57, based on the Common Stock Exchange Ratio.
      Future NBI and BTC dividends are dependent upon their respective earnings
      and financial conditions, government regulations and policies and other
      factors. See "THE MERGER--Dividends" and "--Management and Operations of
      NBI and BTC after the Merger,"

       NBI common stock and BTC Common Stock, see "THE MERGER--Market Prices."
       Because the market price of NBI common stock is subject to fluctuation,
       the market value of the NBI Common Shares that holders of BTC Common

Year Ended December 31, 1995      
    
     Performance Summary. NBI's net income for 1995 was $3,256,000, an increase
of 11.7% over 1994. This produced a return on average assets and average equity
of 1.62% and 15.09%, respectively. In 1994, net income was $2,916,000 which
represented a return on average assets of 1.51% and a return on average equity
of 15.19%. Earnings continue to grow at a strong rate as indicated by the above
ratios. The overall growth rate for capital, however, exceeded the growth rate
for earnings. This, coupled with an increase in net unrealized securities gains,
led to a slight decline in the return on average equity. Net income per share
was $1.90 for 1995 increasing from $1.70 in 1994.      
    
    Net income for the fourth quarter of 1995 was $811,000, an increase of
$164,000 or 25.3% over the fourth quarter of 1994. This increase was due
primarily to a $99,000 improvement in net interest income and a reduction in the
provision for loan losses of $110,000 in comparison to the fourth quarter of
1994. The increase in net income was due to improvement in the net interest
margin and the reduction in the provision for loan losses was due to the
improvement in asset quality.     
    
    Net Interest Income. The yield on interest-earning assets was 8.93% for
1995, increasing from 8.28% in 1994, an increase of 65 basis points. The cost 
of interest-bearing liabilities increased from 3.61% to 4.27% during the same
time period, an increase of 66 basis points, which resulted in a nominal
decrease in the interest rate spread in 1995. The net yield on average 
interest-earning assets which factors in both capital and demand deposits
increased to 5.38% in 1995 up from 5.22% in 1994, a 16 basis point increase. The
increased yield on interest-earning assets was the result of the shifting of
investments to the higher yielding loan portfolio. Deposit growth was nominal as
the need for external funds was not necessary due to excess internal liquidity
which allowed NBB to take a less aggressive stance on obtaining external funds
and avoid the inherent cost of funds in a highly competitive market. Average
interest-earning assets totaled $188,772,000 in 1995 compared to $184,796,000 in
1994. Average interest-bearing liabilities totaled $156,957,000 in 1995 compared
to $156,620,000 in 1994. Net interest income increased by $468,000 in 1995
compared to 1994, which is primarily due to the increase in average 
interest-earning assets, the increase in rates and the shift of funds from
securities to loans.

    Provision and Allowance for Loan Losses. Overall asset quality has shown
substantial improvement in 1995. This improvement has allowed management to
decrease the provision for loan losses and at the same time provide for an
adequate allowance for loan losses.     
    
    Nonperforming loans (consisting of nonaccrual and restructured loans)
totaled $420,000 at December 31, 1995 compared to $649,000 at December 31, 1994.
Nonperforming assets (consisting of nonperforming loans and other real estate
owned) totaled $1,159,000 at December 31, 1995, compared to $1,732,000 at
December 31, 1994. Nonperforming loans and nonperforming assets do not include
accruing loans past due 90 days or more. Accruing loans past due 90 days or more
totaled $210,000 at December 31, 1995, compared to $219,000 at December 31,
1994.     
    
    While continuing efforts are made to improve overall asset quality,
management is unable to estimate when and under what exact terms problem assets
will be resolved.     
    
    Changes in the allowance for loan losses for the year ended December 31, 
1995 and 1994 are as follows:

    At December 31, 1995, the recorded investment in loans which have been
identified as impaired loans, in accordance with Statement of Financial
Standards (SFAS) No. 114, totaled $539,000. Of this amount, $90,000 related to
loans with no valuation allowance, and $449,000 related to loans with a
corresponding valuation allowance of $319,000. For the year ended December 31,
1995, the average recorded investment in impaired loans was approximately
$757,000 and the total interest income recognized on impaired loans was $47,000
of which $5,000 was recognized on a cash basis. The initial adoption to SFAS No.
114 did not require an increase to NBI's allowance for loan losses. Please refer
to "NBI STATISTICAL DATA--Risk Elements and Summary of Loan Loss Experience" for
additional information.     
    
    Noninterest Income.  Noninterest income for 1995 increased 10.5% from 1994.
Fluctuations in the various categories were attributable to general business 
conditions.     
    
    Noninterest Expense. Noninterest expense for 1995 increased by 7%. While
expenses related to Federal Deposit Insurance decreased substantially due to a
refund of premiums, costs associated with other real estate owned increased.
Expenses of $195,000 associated with the proposed Merger also contributed to the
increase.    
    
    Balance Sheet. Total assets at year-end 1995 totaled $203,389,000, an
increase of 1.8%. Loans net of unearned interest outstanding at year-end 1995
were $125,053,000, an increase of 8.1% from the same point in time in 1994. This
growth was funded internally through a shift in investment to loans, increased
internally generated capital and a nominal growth in deposits.     
    
    The use of excess internal liquidity to fund loan growth allowed NBI to
place less emphasis on the procurement of external funds in the market place and
avoid the associated costs of such activities.     
    
    Securities. In late 1995, the Financial Accounting Standards Board granted
financial institutions a one-time opportunity to transfer securities from their
held to maturity to available for sale. Conditions of this transfer provided
that institutions opting to make this shift could do so without bringing into
question their ability and positive intent to hold to maturity their remaining
held to maturity securities. NBI utilized this grace period to shift
approximately $8,199,000 in securities held to maturity to the available for
sale category.

    Capital Resources. Total stockholders' equity increased $2,417,000, or 12%
from 1994 to 1995. Net income, less cash dividends and unrealized gains on
securities available for sale accounted for the increase.      
    
    NBI has operated from a consistently strong capital position. The ratio of
total stockholders' equity to total assets was 11.10% at year-end 1995, compared
to 10.08% at year-end 1994.      
    
    Liquidity.  Management is not aware of any future capital expenditures 
or other significant demands or commitments which would severely impair 
liquidity.

Year Ended December 31, 1995      
    
     Performance Summary. BTC's net income for 1995 was $2,261,000, a decrease
of 5.3% from 1994. This produced a return on average assets and average equity
of 1.28% and 9.36%, respectively. In 1994, net income was $2,387,000, which
represented a return on average assets of 1.38% and a return on average equity
of 15.19%. While earnings continue to remain strong, the decline in net interest
income between 1994 and 1995 was the principal reason for the decline in
earnings. Net income per share was $1.19 for 1995 decreasing from $1.26 in 1994.
         
     Net income for the fourth quarter of 1995 was $462,000, an increase of
$123,000 or 36.3% over the fourth quarter of 1994. Net interest income for the
quarter decreased by $199,000 but was offset by a $257,000 increase in
noninterest income (principally relating to a gain on the sale of securities)
and a $150,000 reduction in noninterest expense.      
    
     Net Interest Income. Interest income increased 4.5% to $12,203,000 for 1995
compared to 1994. Interest expense increased 19.5% to $6,007,000 for 1995
compared to 1994. Since interest income grew at a slower rate than did interest
expense, net interest income and net income both declined. This slower growth
rate resulted from declines in the interest rate spread and in the net yield on
average interest earnings assets and occurred even though period end assets
increased by $4,263,000 from 1994.      
    
     Provision and Allowance for Loan Losses. Overall loan quality remained
satisfactory during 1995 as reflected in a net charge-off ratio of .02%. This
allowed management to take only a nominal provision for loan losses of
$7,000 for 1995.     
    
     Nonperforming loans (consisting of nonaccrual and restructured loans)
totaled $298,000 at December 31, 1995 as compared to $0 at the end of 1994. This
increase is principally attributable to one loan of $255,000.  Nonperforming
assets (consisting of nonperforming loans and     

                                       25
<PAGE>
 
    
other real estate owned) totaled $332,000 at December 31, 1995 compared to
$67,000 at December 31, 1995. Nonperforming loans and nonperforming assets do
not include loans past due 90 days or more. Accruing loans past due 90 days or
more totaled $546,000 at December 31, 1995 compared to $271,000 at December 31,
1994.     
    
    At December 31, 1995 and 1994 the allowances for loan losses was $545,000. 
Net charge-offs were $7,000 in 1995 and $13,000 in 1994. The provision in each
of these years equaled the net charge-offs.      
    
    At December 31, 1995, the recorded investment in loans which have been
identified as impaired loans, in accordance with Statement of Financial
Accounting Standards (SFAS) No. 114, totaled $298,000. Of this amount, $43,000
related to loans with no valuation allowance, and $255,000 related to loans with
a corresponding valuation allowance of $100,000. For the year ended December 31,
1995, the average recorded investment in the impaired loans was approximately
$280,000, and no interest income was recognized. The initial adoption to SFAS
No. 114 did not require an increase to BTC's allowance for loan losses. Please
refer to "BTC STATISTICAL DATA--Risk Elements and Summary of Loan Loss
Experience" for additional information.     
    
    Noninterest Income. Noninterest income for 1995 increased 37.5% to $605,000
as compared to 1994, principally reflecting a $181,000 gain on the sale of
securities.     
    
    Noninterest Expense.  Noninterest expense for 1995 decreased $121,000 or 
3.4% for 1995 compared to 1994.     
    
    Balance Sheet. Total assets at year-end 1995 totaled $177,668,000, an
increase of 2.5%. Net loans at year-end 1995 were $40,220,000, a decrease of
5.5% from 1994. This decrease reflects the continued low loan demand in BTC's
markets. Total deposits increased 1.1% at year-end 1995 to $150,640,000.     
    
    Securities. In late 1995, the Financial Accounting Standards Board granted
financial institutions a one-time opportunity to transfer securities from their
held to maturity portfolio to their available for sale portfolio. Conditions of
this transfer provided that institutions opting to make this shift could do so
without bringing into question their ability and positive intent to hold to
maturity their remaining held to maturity securities. BTC used this grace period
to shift approximately $22,250,000 in securities held to maturity to the 
available for sale category.      
    
    Capital Resources. Total stockholders' equity increased $3,009,000 or 13.3%
from 1994 to 1995. BTC's capital position remained strong with the ratio of
average stockholders' equity to average assets increasing from 13.26% for 1994
to 13.68% for 1995.    
    
    Liquidity.  Management is not aware of any future capital expenditures or
other significant demands or commitments which would severely impair liquidity.

General

    This Prospectus/Proxy Statement is being furnished by BTC to its
stockholders as a Proxy Statement in connection with the solicitation of proxies
by the Board of Directors of BTC for use at the Special Meeting to be held on
_____________, 1996, and any adjournment or adjournments thereof, to consider
and vote upon: (i) a proposal to approve the Merger Agreement, the related Plan
of Merger and the BTC Charter Amendment; and (ii) such other business as may
come before the Special Meeting or any adjournment or adjournments thereof. BTC
stockholders will vote on the Merger Agreement, the related Plan of Merger and
the BTC Charter Amendment as one, unified Proposal and will not vote on each of
the components separately.

    This document is also furnished by NBI to the holders of BTC Common Stock as
a Prospectus in connection with the issuance by NBI of the NBI Common Shares
upon consummation of the Merger.

    After having been submitted, the enclosed proxy may be revoked by the person
giving it, at any time before it is exercised, by: (i) submitting written notice
of revocation of such proxy to the Secretary of BTC; (ii) submitting a proxy
having a later date; or (iii) such person appearing at the Special Meeting and
requesting a return of the

                                       26
<PAGE>
 
proxy. All shares represented by valid proxies will be exercised in the manner
specified thereon. If no specification is made, such shares will be voted in
favor of approval of the Proposal.

    Directors, officers and employees of BTC and NBI may solicit proxies from
BTC stockholders, either personally or by telephone, telegraph or other form of
communication. Such persons will receive no additional compensation for such
services. All other expenses associated with the solicitation of proxies in the
form enclosed will be borne by the party incurring the same, except for printing
expenses, which will be shared equally between NBI and BTC.

    The Board of Directors of BTC has unanimously adopted the Merger Agreement,
the related Plan of Merger and the BTC Charter Amendment as being in the best
interests of BTC and its stockholders and recommends approval of the Proposal by
BTC stockholders. See "THE MERGER--Recommendation of the Board of Directors of
BTC; Reasons for the Merger."

Record Date; Votes Required
    
    The Board of Directors of BTC has fixed _________, 1996, as the Record Date
for stockholders entitled to notice of and to vote at the Special Meeting and,
accordingly, only holders of BTC Common Stock of record at the close of business
on that day will be entitled to notice of and to vote at the Special Meeting.
The number of shares of BTC Common Stock outstanding on the Record Date was
1,888,209, each such share being entitled to one vote.      

    The presence at the Special Meeting, in person or by proxy, of the holders
of a majority of the outstanding shares of BTC Common Stock entitled to vote at
the Special Meeting shall constitute a quorum. If a quorum is present, approval
of the Proposal requires the affirmative vote of more than two-thirds of all
votes entitled to be cast at the Special Meeting by the holders of BTC Common
Stock. Since approval of the Proposal requires the affirmative vote of
stockholders holding more than two-thirds of all the shares of BTC Common Stock
entitled to vote, abstentions will have the same effect as a vote against the
Proposal. Broker non-votes will be counted for purposes of determining the
presence or absence of a quorum and will have the same effect as a vote against
the Proposal.
    
    The directors and executive officers of BTC (including certain of their
related interests) beneficially owned, as of the Record Date, and are entitled
to vote at the Special Meeting approximately 378,806 shares of BTC Common Stock,
which is approximately 20.06 percent of the outstanding shares of BTC Common
Stock entitled to be voted. Directors and executive officers have indicated in
informal discussions that they intend to vote their shares of BTC Common Stock
in favor of the Proposal. As of the Record Date, BTC, acting as fiduciary,
custodian or agent, had sole or shared voting power of 81,350 shares of BTC
Common Stock (constituting approximately 4.3 percent of the outstanding shares).
All such shares will be voted in accordance with the governing agreements or
instruments and applicable laws and regulations.     

    Every stockholder's vote is important. A failure to vote, either by not
returning the enclosed proxy or by checking the ABSTAIN box thereon, will have
the same effect as a vote against approval of the Proposal.


                                   THE MERGER

    The following information relating to the Merger is not intended to be a
complete description of all material information relating to the Merger and is
qualified in its entirety by reference to more detailed information contained
elsewhere in this Prospectus/Proxy Statement, including the Attachments hereto,
and the documents incorporated herein by reference. Copies of the Merger
Agreement (including the related Plan of Merger) and the BTC Charter Amendment
are set forth in Attachment A and Attachment B to this Prospectus/Proxy
Statement and reference is made thereto for a complete description of the terms
of the Merger and the BTC Charter Amendment. Stockholders of BTC are urged to
read the Merger Agreement and the BTC Charter Amendment carefully.

General
    
    Under the terms of the Merger Agreement, NBI Interim will merge with and
into BTC, and BTC will continue its operations as a wholly owned subsidiary of
NBI. Upon consummation of the Merger each outstanding share of BTC Common Stock
(excluding any Dissenting Shares and excluding any NBI/BTC Held Shares) will be
converted, by virtue of the Merger, automatically and without any action on the
part of the holder thereof, into the right to receive one share of NBI common
stock. The Common Stock Exchange Ratio takes into account the NBI Stock Split.
See "--NBI Stock Split." Each holder of BTC Common Stock who would otherwise be
entitled to a fractional share of NBI common stock will receive cash in lieu
thereof in an amount determined by multiplying (i) the closing sale price per
share of BTC common stock for the final bona fide trade on the last day on which
such stock has traded prior to the Merger Effective Date, as reflected on the
NASD Bulletin Board by (ii) the fraction of a share of NBI common stock to which
such holder would otherwise be entitled.
     
   For a discussion of the rights of holders of BTC Common Stock who elect to
dissent from the Merger, see "--Dissenters' Rights."

Merger Effective Date
    
    Subject to the conditions to the obligations of the parties to effect the
Merger, the Merger will become effective at 11:59 p.m. on the date that the
Virginia Commission issues a certificate of merger evidencing the effectiveness
of the Merger. Unless otherwise agreed upon in writing between NBI and BTC, and
subject to the conditions to the obligations of the parties to effect the
Merger, the parties have agreed to use their reasonable efforts to cause the
Merger Effective Date to occur as soon as practicable following the satisfaction
of: (i) approval of the Proposal by the requisite vote of the BTC stockholders;
(ii) receipt of the Required Regulatory Approvals and the expiration of any
statutory waiting periods relating thereto; and (iii) procurement of all other
regulatory consents and approvals and satisfaction of all other requirements
prescribed by law which are necessary to consummate the Merger; provided,
however, that no approval or consent of paragraph (ii) or (iii) above shall have
imposed any condition or requirement which would materially adversely impact the
economic or business benefits of the transactions contemplated by the Merger
Agreement and the related Plan of Merger so as to render inadvisable the
consummation of the Merger. Subject to the foregoing, it is currently
anticipated that the Merger will be consummated in the second quarter of 1996.
The Board of Directors of either NBI or BTC may terminate the Merger Agreement
if the Merger Effective Date does not occur on or before June 30, 1996. See "--
Conditions to Consummation; Termination."      

Exchange of BTC Certificates

    As promptly as practicable after the Merger Effective Date, NBI will send or
cause to be sent to each holder of record of BTC Common Stock, transmittal
materials for use in exchanging all of such holder's certificates representing
BTC Common Stock (other than Dissenting Shares) for a certificate or
certificates representing the NBI Common Shares to which such holder is entitled
and a check for such holder's fractional share interest, as appropriate. The
transmittal materials will contain information and instructions with respect to
the surrender and exchange of such certificates.

    BTC STOCKHOLDERS SHOULD NOT SEND IN THEIR CERTIFICATES UNTIL THEY RECEIVE 
THE LETTER OF TRANSMITTAL FORM AND INSTRUCTIONS.

    Upon surrender of all of the certificates for BTC Common Stock registered in
the name of the holder of BTC Common Stock (or indemnity satisfactory to NBI, in
its judgment, after consultation with the President of BTC, if any of such
certificates are lost, stolen or destroyed), together with a properly completed
letter of transmittal, NBI, or an exchange agent selected by NBI, will mail to
such holder a certificate or certificates representing the number of NBI Common
Shares to which such holder is entitled, together with all undelivered dividends
or distributions in respect of such shares and, where applicable, a check for
the amount representing any fractional share interest (in each case, without
interest).

                                       28
<PAGE>
 
    After the Merger Effective Date, to the extent permitted by law, former
holders of record of BTC Common Stock will be entitled to vote at any meeting of
holders of NBI common stock, the number of NBI Common Shares into which their
BTC Common Stock has been converted, regardless of whether they have surrendered
their BTC Common Stock certificates. Dividends declared by NBI after the Merger
Effective Date will include dividends on all NBI Common Shares issued in the
Merger, but no dividend or other distribution payable to the holders of record
of NBI Common Shares at or as of any time after the Merger Effective Date will
be paid to the holder of any BTC Common Stock certificates until such holder
physically surrenders all such certificates as hereinabove described. Promptly
after such surrender, all undelivered dividends and other distributions and,
where applicable, a check for the amount representing any fractional share
interest, will be delivered to such holder (without interest). After the Merger
Effective Date, the stock transfer books of BTC will be closed and there will be
no transfers on the transfer books of BTC of the shares of BTC Common Stock that
were issued and outstanding immediately prior to the Merger Effective Date.

Background of the Merger
    
    In the twelve-month period preceding the discussions with NBI, BTC had
preliminary discussions with two other small financial institutions in Southwest
Virginia. These discussions were initiated by the other institutions. In each
case, the preliminary discussions were terminated because the parties concluded
that there was no financial basis on which a mutually acceptable combination
could be achieved. BTC never conducted any preliminary discussions with NBI
until the ones which led to the Merger Agreement.      
    
    In December 1994, during an informal telephone conversation between James G.
Rakes, President and Chief Executive Officer of NBI, and A. A. Crouse, Executive
Vice President of BTC, the idea of a possible affiliation of BTC with NBI was
raised by Mr. Rakes. While Mr. Rakes and Mr. Crouse knew each other prior to the
telephone call, they had no preexisting business relationship, other than in
connection with BTC's purchase, in the normal course of business, of loan
participations from NBI. Messrs. Dodson and Crouse thereafter reviewed available
information concerning NBI and NBB and concluded that there was a sufficient
basis to believe that discussions of some type of affiliation would be
appropriate. In particular, the similar size of the two institutions, their
respective earnings records and their similar business philosophies were
considered by BTC management to be positive factors. Mr. Dodson subsequently
contacted Mr. Rakes by telephone to determine if NBI wished to discuss the
possible affiliation on a serious basis. That telephone call resulted in a
decision to meet in early 1995 to discuss the subject.      

    In January, 1995, Mr. Rakes, NBI Board Chairman Robert E. Christopher, Jr.
and NBI Board Vice-Chairman Charles L. Boatwright met with Messrs. Dodson and
Crouse and BTC Board Chairman T.C. Bowen, Jr. to explore their interest in
initiating a process to determine if there might be a basis for holding
definitive negotiations on such an affiliation. It was decided at such meeting
that the executive officers would brief their respective Boards of Directors on
the course and status of discussions. It was also determined that a prudent way
to evaluate the desirability of proceeding with definitive negotiations and to
establish an initial basis for any such negotiations would be to retain an
independent consultant to provide information relative to a fair market
valuation of 100% of the outstanding common stock of both entities and a fair
and equitable stock exchange ratio. On February 8, 1995, the NBI Board heard a
report from Mr. Rakes concerning the progress of negotiations and authorized Mr.
Rakes to engage in further discussions. At the meeting of the BTC Board of
Directors on February 14, 1995, Mr. Dodson made a presentation regarding NBI and
provided the Board with a status report of the discussions. At such meeting,
BTC's Board of Directors unanimously approved the continuation of negotiations.
    
    With their respective Board of Directors' approval, NBI and BTC jointly
engaged Alex Sheshunoff & Co. Investment Banking ("Sheshunoff") to provide a
report on preliminary valuation matters (the "Sheshunoff Report"). BTC and NBI
agreed to divide equally the $10,000 fee for the Sheshunoff Report. Sheshunoff
provides a number of services to financial institutions throughout the United
States, including data gathering, consulting and investment banking. It is
nationally ranked on the basis of the number of merger and acquisition
transactions on which it advises and is generally engaged in the valuation of
financial institutions and their securities in connection with mergers,
acquisition and valuation for corporate and other purposes. There was no prior
material relationship between      

                                       29
<PAGE>
 
    
Sheshunoff and either NBI or BTC. There was no restriction placed on the scope
of Sheshunoff's Report nor the procedures followed.     
    
    The Sheshunoff Report was delivered to both NBI and BTC in April, 1995. Such
Report included an analysis of both institutions and a suggested exchange ratio
of 0.900 shares of NBI common stock for each share of BTC Common Stock, with the
shareholders of NBI and BTC owning 50.22% and 49.78%, respectively, of NBI after
the Merger. The exchange ratio proposed by Sheshunoff was based on its
conclusion of the fair market values of NBI and BTC. After determining the
respective fair market value of the outstanding common stock of each institution
at December 31, 1994, the proposed exchange ratio was derived by assigning to
each institution its respective proportion of the combined fair market value.
Each of the institution's fair market value was determined by analyzing (i) its
book value at December 31, 1994; (ii) its adjusted book value (its book value
per share adjusted for the average price to book value of banks sold in Virginia
during 1994); (iii) its market value; (iv) its adjusted earning value (its
earnings per share for 1994 and 1995 (estimated) compared to the average price
to earnings ratio of banks sold in Virginia during 1994); (v) its net present
value (the value of its future earnings stream); and (vi) a cash flow analysis.
Sheshunoff relied upon the accuracy and completeness of all financial and other
data provided by NBI and BTC without independent verification. No independent
appraisal of the assets or liabilities of NBI or BTC was rendered by Sheshunoff.
The suggested exchange ratio in the Sheshunoff Report was modified to the
current one-to-one Common Stock Exchange Ratio, after taking into account the
NBI Stock Split.      
    
    At an NBI Board session on May 10, 1995, the Board reviewed the local and
national banking environment, NBI's current performance and business plan and
strategic issues related to NBI. In those discussions, the Board noted the
increase in merger activity among large banks and the corresponding decrease in
the total number of banks in the United States. Because of these mergers, and
also because of changes in national banking laws which now permit or will soon
permit interstate branching and banking, the Board concluded that, in the near
future, NBI is likely to face competition from a new group of financial
institutions which are larger than current competitors. The directors reviewed
NBI's positive past performance as compared to its peers and discussed how NBB,
its sole subsidiary community bank, might best compete in the future. The Board
determined that the market served by community banks could well become larger in
the future if the contrast between large and small banks becomes more defined.
The Board concluded that community banks, with their traditional emphasis on
personalized and responsive service and community involvement, should be able to
effectively and profitably compete for certain segments of the financial
services market. The Board further concluded that NBI is well-positioned,
because of its location, historical performance, asset quality, capital,
management and employees to compete among local community banks. There was
unanimous agreement that NBI's subsidiary should remain a community bank.      
    
    The Board discussed strategies which might enhance NBB's ability to most
effectively compete in the future as a community bank. The discussion focused on
changing technology and the need to position NBI to be able to take advantage of
technological advances which fit into NBI's overall corporate goal of providing
quality financial services in a customer-oriented business setting. The Board
concluded that a business combination with another community bank that espoused
a compatible business philosophy would result in a company of sufficient size
and capital to enable it to acquire and efficiently utilize desirable
technology, without sacrificing either party's ability to continue to operate
within its market area as a traditional community bank. The Board heard a
detailed presentation of a draft of the Sheshunoff Report. The Board concluded,
from a financial point of view, that the information in the Report, at least on
a preliminary basis, supported the prospect that BTC could be a suitable partner
in a future business combination.      
    
    At the BTC Board meeting on May 9, the Sheshunoff Report was also presented
to and discussed by the BTC Board of Directors. The concept of the NBI Stock
Split was also discussed. The Sheshunoff Report was concluded to be fair and
reasonable by the BTC Board of Directors, and the BTC executive officers were 
authorized to continue negotiations on such basis.      

    Representatives of NBI and BTC met on May 18, 1995, to discuss the status of
negotiations. The principal result of such meeting was that both Messrs. Dodson
and Rakes would make recommendations to their respective

                                       30
<PAGE>
 
Boards of Directors that the Merger would be beneficial to both parties and that
a confidentiality agreement should be approved to protect further due diligence.
It was also decided that each of the parties would employ their own financial
adviser to issue a fairness opinion.
    
    At the BTC Board of Directors meeting on June 13, 1995, Mr. Dodson made a
presentation on the status of negotiations with NBI and reviewed various aspects
of how the two institutions would be managed after the Merger. The advantages of
an affiliation between BTC and NBI were discussed, including NBI's strong loan
demand, its higher stock price and the economics of its local market. The BTC
Board decided to proceed further with discussions and authorized the execution
of a confidentiality agreement in connection with additional due diligence.     
    
    At an NBI Board of Directors meeting held on June 14, 1995, Mr. Rakes made a
detailed presentation concerning issues which the NBI Board might wish to
consider in evaluating the proposed Merger. This presentation focused on the
preservation and enhancement of NBI shareholder value. One stated advantage of
the proposed Merger was the ability to increase the size of NBI to better
position it to meet future competition without the adverse effects of paying
high control premiums usually associated with more traditional purchase
transactions. It was noted that the proposed Merger would allow BTC to retain
its name, management would not change, NBB directors would be in the majority on
the Board of NBI after the Merger and current NBI stockholders would retain
ownership of a majority of outstanding NBI common stock. The near doubling of
the stockholder base, with the attendant possibility that NBI common stock will
be more widely traded, was viewed as a distinct advantage of the proposed
Merger. The suitability of BTC as a merger partner was listed as an advantage.
The strengths of the capital, earnings and management of BTC, the compatible
business philosophies of the two companies and the physical proximity of the two
were factors discussed in this context. The possibility that, after the Merger,
both bank subsidiaries could continue to do business under their current names,
with existing management, while jointly working toward combining certain support
functions in a deliberate and planned manner was seen as an advantage. Possible
disadvantages and problems of the proposed Merger also were discussed. These
included the difficulties inherent in unifying NBI's new Board of Directors, the
development of a new corporate culture, future selection of NBI's senior
management team and general corporate governance issues.      
    
    At the June 14 NBI Board Meeting, there was also discussion of the best way
to continue discussions with BTC. It was determined that Mr. Rakes should hold
further conversations with Mr. Dodson, that the companies should begin an
exchange of more detailed information and that NBI should undertake preliminary
due diligence. To that end, Mr. Rakes was authorized to enter into a
confidentiality agreement.      

    During the latter part of June, the confidentiality agreement was executed
and the parties met to exchange and review information concerning all phases of
each institution which included loan, regulatory and financial reports. After
such review, it was agreed that the presidents of the respective institutions
would recommend to their Board of Directors that a written agreement reflecting
the Merger be prepared upon completion of further negotiations.

    At its meeting on July 11, 1995, BTC's Board of Directors again discussed a
possible affiliation with NBI and unanimously approved the hiring of Baxter,
Fentriss as BTC's financial adviser in connection with the Merger and also
approved the hiring of special legal counsel to aid in the Merger.

    Beginning in late June and continuing through July and August of 1995, Mr.
Rakes and NBI's legal counsel were engaged in lengthy negotiations with Mr.
Dodson and BTC's legal counsel regarding the terms of a possible definitive
merger agreement. Mr. Rakes reported to the Board of Directors at a meeting held
on July 12, 1995, that discussions with BTC were progressing, and he recommended
that NBI retain McKinnon & Company, Inc., an investment banking firm from
Norfolk, Virginia ("McKinnon"), to serve as financial adviser to the Board of
Directors of NBI to determine from a financial point of view whether the
proposed exchange terms between NBI and BTC are fair to the stockholders of NBI.
A contract with McKinnon was entered into on July 20. Between July 20 and July
31, teams from McKinnon and NBI performed certain due diligence reviews at BTC.
BTC and its representatives likewise completed due diligence at NBI during this
period.

                                       31
<PAGE>
 
    A special meeting of the Board of NBI was held on July 31, 1995. William J.
McKinnon, President of McKinnon, presented a preliminary fairness opinion to the
Board. At that same meeting, by unanimous agreement of all directors who were
present, it was decided that NBI should complete a final draft of a definitive
merger agreement.

    At its meeting on August 8, 1995, BTC's Board of Directors reviewed the
status of discussions with NBI. A draft merger agreement and related documents
were presented and reviewed. Certain terms requiring final negotiations were
identified and discussed. Additionally, a preliminary fairness opinion from
Baxter, Fentriss to be dated the next day was presented and reviewed by the
directors. The BTC Board of Directors unanimously approved the Merger and
authorized Mr. Dodson to complete negotiations of certain final terms of the
Merger Agreement and to execute the Merger Agreement when it was completed to
his satisfaction.

    At a NBI Board meeting held on August 9, 1995, Mr. Rakes and NBI's counsel
reviewed with the NBI Board members pertinent points of a draft merger agreement
and related documents. In addition, there was a lengthy discussion of the
benefits to NBI and its stockholders of the proposed Merger. At that meeting,
the Board unanimously voted in favor of the Merger, and Mr. Rakes was authorized
to negotiate certain final terms of the Merger Agreement and to execute the
Merger Agreement when it was completed to his satisfaction.

    The Merger Agreement was signed by both parties on August 28, 1995.

Recommendation of the Board of Directors of BTC; Reasons for the Merger

    The Board of Directors of BTC has determined that the Merger is in the best
interests of BTC and its stockholders. The Board was influenced by a number of
factors in arriving at this determination, though it did not assign any specific
or relative weight to these factors in its consideration. Among the factors
considered were:
        
           (i)       The Board of Directors of BTC believes that the Common
    Stock Exchange Ratio provided for in the Merger Agreement will provide a
    fair price to its stockholders for their shares of BTC Common Stock. 
    See "--General." Baxter Fentriss, BTC's financial adviser, also concluded
    that the Common Stock Exchange Ratio was fair to the BTC stockholders from a
    financial point of view. See "--Opinions of BTC's Financial Adviser."     

           (ii)      The Merger is anticipated to be tax-free for federal income
    tax purposes for the stockholders of BTC Common Stock (other than in respect
    to cash paid in lieu of fractional shares or in respect to dissenting
    stockholders).

           (iii)     The due diligence examination conducted by BTC indicated
    that NBI is strong in capital, earnings and management.
        
           (iv)      The NBI common stock after the Merger is expected to afford
    greater market liquidity as compared to the current minimal trading of BTC's
    Common Stock. NBI's covenant to use its best efforts to seek listing of the
    NBI common stock after the Merger on Nasdaq was considered especially
    important in this regard. See "--Market Prices."      

           (v)       The Board of Directors' review of the provisions of the
    Merger Agreement, the related Plan of Merger and the BTC Charter Amendment.

           (vi)      The Merger may provide BTC's customers with expanded access
    to bank services and facilities in the future.
        
           (vii)     The Merger provides a strategic market fit to BTC through a
    combination with NBI. NBI's service areas are considered by BTC's Board of
    Directors to be among the strongest in Southwest      

                                       32
<PAGE>
 
    Virginia. With BTC's low loan to deposit ratio, loan demand from these areas
    may provide an opportunity for BTC, through loan participations or
    otherwise, to utilize its deposits on a more profitable basis.
    
           (viii)    The combined resources of BTC and NBI will provide a
    realistic alternative to larger financial institutions which are resulting
    from consolidation within the banking industry, and BTC, after the Merger,
    is expected to be in a better position to compete with the existing
    financial institutions in BTC's market area. It is also anticipated that
    centralized management and certain economies of scale will eventually
    increase the efficiency and profitability of both institutions, including
    that certain departments of the respective banks, such as data processing,
    trust and risk management, may be centralized and consolidated at some time,
    although there are no specific plans at this time to do so. Additionally,
    although NBI currently has no specific plans in this regard, it is expected
    that the Merger will allow NBB and BTC to consider utilizing technologies
    which would be cost prohibitive for either party separately.      
    
    Based on these matters, BTC's Board of Directors unanimously adopted the
Merger Agreement, the related Plan of Merger and the BTC Charter Amendment as
being in the best interests of BTC and its stockholders.      

    BTC'S BOARD OF DIRECTORS RECOMMENDS THAT BTC STOCKHOLDERS VOTE FOR APPROVAL
OF THE PROPOSAL.

Opinions of BTC's Financial Adviser

    Baxter Fentriss has acted as financial adviser to BTC in connection with the
Merger. Baxter Fentriss did not assist BTC in identifying prospective parties
with which to affiliate. On August 7, 1995, Baxter Fentriss delivered to BTC its
initial opinion dated as of August 9, 1995, that, on the basis of matters
referred to therein, the Common Stock Exchange Ratio is fair, from a financial
point of view, to the holders of BTC Common Stock. In rendering its opinion,
Baxter Fentriss consulted with the managements of BTC and NBI, reviewed the
Merger Agreement and related documents and reviewed certain additional materials
made available by the managements of NBI and BTC.

    In addition, Baxter Fentriss discussed with the managements of BTC and NBI
their respective businesses and outlook. Baxter Fentriss was not involved in the
negotiations with NBI and did not initiate merger discussions at the request of
BTC. No limitations were imposed by BTC's Board of Directors upon Baxter
Fentriss with respect to the investigation made or procedures followed by it in
rendering its opinion. The full text of Baxter Fentriss' written opinion as
reissued as of the date of this Prospectus/Proxy Statement (which is
substantially identical to is initial opinion, dated as of August 9, 1995), is
attached as Attachment C to this Prospectus/Proxy Statement and should be read
in its entirety with respect to the procedures followed, assumptions made,
matters considered, and qualification and limitations on the review undertaken
by Baxter Fentriss in connection therewith.

    Baxter Fentriss' opinion is directed to BTC's Board of Directors only, and
is directed only to the fairness, from a financial point of view, of the Common
Stock Exchange Ratio. It does not address BTC's underlying business decision to
effect the Merger, nor does it constitute a recommendation to any BTC
stockholder as to how such stockholder should vote with respect to the Merger,
the related Plan of Merger and the BTC Charter Amendment at the Special Meeting
or as to any other matter.

    Baxter Fentriss' opinion was one of many factors taken into consideration by
BTC's Board of Directors in making its determination to approve the Merger
Agreement, the related Plan of Merger and the BTC Charter Amendment and the
receipt of Baxter Fentriss' opinion is a condition precedent to BTC's
consummating the Merger. The opinion of Baxter Fentriss does not address the
relative merits of the Merger as compared to any alternative business strategies
that might exist for BTC or the effect of any other business combination in
which BTC might engage.

    Baxter Fentriss, as part of its investment banking business, is continually
engaged in the valuation of financial institutions and their securities in
connection with mergers and acquisitions and valuations for estate, corporate
and other purposes. Baxter Fentriss is a nationally recognized adviser to firms
in the financial services industry on mergers and acquisitions. BTC selected
Baxter Fentriss as its financial adviser because Baxter Fentriss is an
investment banking firm focusing on banking transactions, and because of the
firm's extensive experience in transactions similar to the Merger. Baxter
Fentriss is not affiliated with NBI or BTC.

    In connection with rendering its opinion to BTC's Board of Directors, Baxter
Fentriss performed a variety of financial analyses. In conducting its analyses
and arriving at its opinion as expressed herein, Baxter Fentriss considered such
financial and other factors as it deemed appropriate under the circumstances,
including, among others, the following: (i) the historical and current financial
condition and results of operations of NBI and BTC, including interest income,
interest expense, interest sensitivity, noninterest income, noninterest expense,
earnings, book value, return on assets and equity, capitalization, the amount
and type of non-performing assets, the impact of holding certain non-earning
real estate assets, the reserve for loans losses and possible tax consequences
resulting from the Merger; (ii) the business prospects of NBI and BTC; (iii) the
economies of NBI's and BTC's respective market areas; (iv) the historical and
current market for BTC Common Stock and for NBI common stock; and (v) the nature
and terms of certain other merger transactions that it believed to be relevant.
Baxter Fentriss also considered its assessment of general economic, market,
financial and regulatory conditions and trends, as well as its knowledge of the
financial institutions industry, its experience in connection with similar
transactions, its knowledge of securities valuation generally, and its knowledge
of merger transactions in Virginia.
    
    In connection with rendering its opinion as set forth in Attachment C,
Baxter Fentriss reviewed (i) the Merger Agreement and related documents; (ii)
drafts of this Prospectus/Proxy Statement; (iii) the Annual Reports to
Stockholders of NBI and BTC, as well as the audited financial statements of BTC
and NBI for the year ended December 31, 1994 and quarterly information of BTC
and NBI for the nine months ended September 30, 1995; (iv) pro forma combined
unaudited condensed balance sheets as of December 31, 1994 and September 30,
1995, as well as pro forma combined unaudited condensed statements of income
before cumulative effect of change in accounting principle for the years ended
December 31, 1994, 1993 and 1992 and for the nine months ended September 30,
1995 and 1994; and (v) certain additional financial and operating information
with respect to the business, operations and prospects of NBI and BTC as it
deemed appropriate. Baxter Fentriss also (i) held discussions with members of
the senior management of NBI and BTC regarding the historical and current
business operation, financial condition and future prospects of their respective
companies; (ii) reviewed the historical market prices and trading activity for
BTC Common Stock and NBI common stock; (iii) compared the results of operations
of BTC with those of certain banking companies that it deemed relevant; (iv)
analyzed the pro forma financial impact of the Merger on NBI; (v) analyzed the
pro forma financial impact of the Merger on BTC; and (vi) conducted such other
studies, analyses, inquiries and examinations as Baxter Fentriss deemed
appropriate.      

    The following is a summary of selected analyses performed by Baxter Fentriss
in connection with its opinion:
    
    1.  Stock Price History. Baxter Fentriss studied the history of the trading
prices and volumes for BTC Common Stock and NBI common stock and compared that
to publicly traded banks in Virginia and to the Common Stock Exchange Ratio
offered by NBI. As of September 30, 1995, BTC's book value was $25.0 million or
$13.25 per share. Both BTC and NBI stock trade infrequently and have less
liquidity than other publicly traded Virginia banks. Baxter Fentriss concluded
the Merger could create a financial institution with increased investor and
brokerage coverage, increased trading volume, and, therefore, the potential for
increased liquidity.      
    
    2.  Comparative Analysis. Baxter Fentriss compared the price to earnings
multiple, price to book multiple and price to assets multiple of the Common
Stock Exchange Ratio with 27 other merger transactions in Virginia announced
since December 31, 1992. Based on September 30, 1995 financial data and an NBI
split adjusted stock price of $22.28 as of November 29, 1995, the estimated
price to book multiple of 1.68x ranks fourteenth, the estimated price to
earnings multiple of 17.6x ranks ninth, and the estimated price to assets of
23.7% ranks third.      

                                       34
<PAGE>
 
    
This review suggested better than average pricing considering the three factors,
especially given a transaction of this type. The comparative multiples included
both bank and thrift sales.      
    
    3.  Baxter Fentriss considered the pro forma impact of the Merger and
concluded the Merger should have a positive long-term impact on NBI and BTC
stockholders. The transaction is estimated to be accretive to NBI December 31,
1996 book value with an estimated positive impact to earnings of $0.01 per share
beginning in year two and $0.04 per share on a five-year cumulative basis. The
transaction, while estimated to be dilutive to BTC's book value initially, is
estimated to be accretive to earnings by $0.39 per share in year one and $2.17
per share on a five-year cumulative basis. Pro forma dilution to book value is
estimated to be recovered after approximately three years of combined
operations. BTC's dividends per share are estimated to improve approximately 16%
immediately.      
    
    4.  Baxter Fentriss performed a discounted cash flow analysis to determine
hypothetical present values for a share of BTC Common Stock and NBI common stock
as long-term investments. Using a discount rate of 12%, long-term return on
assets of 1.40% for BTC and 1.60% for NBI, and market growth rates of 4% for BTC
and 6% for NBI, Baxter Fentriss estimated the relative present value (and
estimated ownership of total combined operations) of BTC and NBI to be $35.8
million (46.16%) and $41.7 million (53.84%), respectively. Based on this
analysis, Baxter Fentriss concluded that the Common Stock Exchange Ratio and
resultant 49.78% ownership of NBI common stock after the Merger was fair and
reasonable in a transaction of this type.
     
    Using publicly available information on NBI and applying the capital
guidelines of banking regulators, Baxter Fentriss' analysis indicated that the
Merger would not seriously dilute the capital and earnings capacity of NBI and
would, therefore, likely not be opposed by the banking regulatory agencies from
a capital perspective. Furthermore, Baxter Fentriss considered the likely market
overlap and the Federal Reserve guidelines with regard to market concentrations
and did not believe there to be an issue with regard to possible antitrust
concerns.

    Baxter Fentriss has relied, without any independent verification, upon the
accuracy and completeness of all financial and other information reviewed.
Baxter Fentriss has assumed that all estimates, including those as to possible
economies of scale, were reasonably prepared by management and reflect
management's best current judgments. Baxter Fentriss did not make an independent
appraisal of the assets or liabilities of either BTC or NBI and has not been
furnished such an appraisal.

    Baxter Fentriss was paid an amount equal to $10,000 plus reasonable out-of-
pocket expenses for its services. BTC has agreed to indemnify Baxter Fentriss
against certain liabilities, including certain liabilities under the federal
securities laws.

NBI Reasons for the Merger

    The Board of Directors of NBI believes that the terms of the Merger are fair
to and in the best interests of NBI and its stockholders. In unanimously
approving the Agreement, the Board of Directors considered a number of factors,
including the following:

           (i) The Board of Directors believes that the Common Stock
    Exchange Ratio provided for in the Merger Agreement represents fair
    consideration for the BTC Common Stock. In addition, McKinnon, NBI's
    financial adviser, concluded that the terms of the Merger are fair to the
    stockholders of NBI from a financial point of view.

           (ii) The Merger should assist NBI in retaining its local
    identity and control.

           (iii) It is anticipated that the Merger will increase the
    liquidity of NBI's common stock by expanding the size of the stockholder
    base and because of NBI's intention (as stated in the Merger Agreement) to
    use its best efforts to list NBI common stock on the Nasdaq.

                                       35
<PAGE>
 
           (iv)  The Merger will allow NBI to nearly double its current size and
    to expand into adjacent service areas with a long established subsidiary
    community bank that is strong in capital, earnings and management.

           (v)   Because BTC has a relatively low loan to deposit ratio, it is
    expected that the Merger will result in very close cooperation between the
    subsidiary banks in funding loan demand in NBI's current service area.

           (vi)  The Merger is expected to result in a stronger and deeper
    management team that will allow NBI to effectively address changes in
    technology, regulations, competition and products and services.

           (vii) The additional capital brought to NBI by the Merger will allow
    NBI to consider a wider range of future expansion opportunities.

Management and Operations of NBI and BTC after the Merger

    At the Merger Effective Date, BTC will become a wholly owned subsidiary of
NBI, but will maintain its separate name, identity and operations. No change in
the Board of Directors or executive officers of BTC will result from the Merger.
It is also contemplated that BTC will maintain all of its current offices.

    After the Merger Effective Date, the Board of Directors of NBI will be
comprised of nine persons, one of whom will be Mr. James G. Rakes, President of
NBI and NBB, four of whom will be BTC Board Representatives and four of whom
will be persons currently members of the Board of Directors of NBI. No change in
the executive officers of NBI will result from the Merger.
    
    The Board of BTC has selected T. C. Bowen, Jr., A. A. Crouse, R. E. Dodson
and William T. Peery as the initial BTC Board Representatives. NBI has agreed to
take certain actions described below, including amendments to its Bylaws, in
order to assure that certain actions affecting BTC will not be initiated by NBI
without the consent of at least one of the BTC Board Representatives before
January 1, 2001.      

    Effective as of the Merger Effective Date, NBI has agreed to cause its
Bylaws to be amended as follows: (i) the number of NBI directors shall be set at
nine; (ii) the affirmative vote of six out of nine NBI directors shall be
required to approve any of the following actions: (a) membership on the Board of
Directors of BTC (provided, however, that a director of BTC may be removed by
action of NBI as sole stockholder of BTC by the vote of a simple majority of NBI
directors in the event that such director commits a violation of law applicable
to his or her duties as a director of BTC which has a material adverse effect on
BTC or engages in any conduct in connection with his or her duties as a director
for which he or she would not be entitled to indemnification under the Articles
of Incorporation of BTC), (b) amendments to the Articles of Incorporation or
Bylaws of BTC, (c) the merger, consolidation or sale of all or substantially all
of the assets of BTC, or (d) a recommendation to the stockholders of NBI to
merge, consolidate or sell all or substantially all of the assets of NBI, where
such recommendation is required by law; (iii) to change the provisions requiring
that NBI directors also be NBB directors to permit directors of BTC to serve on
the NBI Board as well; and (iv) the Executive Committee shall not authorize or
approve any action on behalf of NBI described in (ii) above. NBI has agreed that
these Bylaws amendments shall not be amended or rescinded by action of its Board
of Directors without the affirmative vote of at least six directors until
January 1, 2001, on and after which time such Bylaw amendments may be amended or
rescinded by a simple majority vote of its Board of Directors as provided in the
Bylaws of NBI.

    There currently are nine members and one vacancy on the NBI Board of
Directors. Effective as of the Merger Effective Date, NBI shall obtain the
resignations of four directors currently serving on the NBI Board of Directors,
spread as nearly equally as possible among the three classes of NBI directors,
thereby reducing the number of persons then serving on the NBI Board to five
and, in conjunction with an amendment of NBI's Bylaws, creating four vacancies
on the NBI Board of Directors (the "NBI Board Vacancies"). NBI has agreed that
the remaining five NBI directors will fill the NBI Board Vacancies with four BTC
Board Representatives by electing them to the NBI Board Vacancies until the next
following annual stockholders' meeting. Unless a BTC Board Representative's

                                       36
<PAGE>
 
service on the Board is terminated for cause in accordance with the provisions
of NBI's Articles of Incorporation, NBI has agreed to renominate the BTC Board
Representatives for reelection to the remaining terms of their respective
classes at the next annual stockholders' meeting following the Merger Effective
Date and shall continue to renominate for election by the NBI stockholders those
of the BTC Board Representatives who must stand for reelection as a result of
the expiration of their classes as of the NBI annual stockholders' meetings in
1997, 1998, 1999 and 2000, respectively. In the event of the death or
resignation of any BTC Board Representative creating a vacancy on the NBI Board
of Directors, at any time before the NBI annual stockholders' meeting in 2000,
the Board of BTC shall be entitled to select a replacement to fill such vacancy
and the NBI Board shall elect such replacement to fill the vacancy created by
such death or resignation. The NBI Board of Directors also shall, following
consummation of the Merger, appoint an Executive Committee consisting of five of
its members, two of whom shall be BTC Board Representatives.

Interests of Certain Persons
    
    NBI has agreed that for six years after the Merger Effective Date, NBI will
cause BTC and any successor thereto or any subsidiary thereof, to indemnify any
person who has rights to indemnification from BTC, to the same extent and on the
same conditions as such person is entitled to indemnification pursuant to BTC's
Articles of Incorporation as in effect on the date of the Merger Agreement, to
the extent legally permitted to do so, with respect to matters occurring on or
prior to the Merger Effective Date. The adoption of the BTC Charter Amendment
will not affect any person's right, if any, to such indemnification. NBI also
has agreed to use its reasonable best efforts to provide coverage to the
existing directors and officers of BTC under NBI policy or policies of directors
and officers liability insurance on the same or similar terms then in effect for
directors and officers of NBB, and BTC shall reimburse NBI for the additional
premium incurred by it in connection with providing such coverage. All directors
and officers of BTC will have an interest in and could benefit from the
provisions of the BTC Charter Amendment at the potential expense of NBI
shareholders. See "--BTC Charter Amendment."     

    It is the intention of NBI and BTC that, as soon as administratively
practicable following the Merger Effective Date, employees of BTC will be
entitled to participate in NBI's severance, benefit and similar plans (excluding
qualified retirement plans) on the same terms and conditions as employees of NBI
and its subsidiaries, giving effect to years of service and prior earnings with
BTC as if such service were with NBI. NBI and BTC have agreed to engage experts,
including, but not limited to, actuaries, to make recommendations as to how the
qualified retirement plans should be handled and shall use their best efforts to
come to an agreement regarding all benefit plans which shall be in the form of
an amendment to the Merger Agreement. To the extent possible, no employee of BTC
who elects coverage by NBI's medical insurance plans will be excluded from
coverage thereunder (for such employee or any other covered person) on the basis
of a pre-existing condition that was not also excluded under BTC's medical
insurance plans and that, if an NBI plan will not take the place of a BTC plan
pursuant to the Merger Agreement, such BTC benefit plan shall remain in effect
until the benefit plan of NBI is available for participation by the officers and
employees of BTC.

Certain Federal Income Tax Consequences
    
    The following summarizes all material federal income tax consequences of the
Merger to a BTC stockholder who holds BTC Common Stock as a capital asset, and
may not apply to special situations, such as BTC stockholders that are insurance
companies, securities dealers, financial institutions or foreign persons.      
     
    Neither NBI nor BTC has requested a ruling from the Internal Revenue Service
in connection with the Merger. The following discussion summarizes the opinion
of KPMG, NBI's independent auditors, with respect to all material federal income
tax consequences of the Merger to BTC's stockholders.      

                                       37
<PAGE>
 
    KPMG has advised NBI and BTC that in its opinion:

           (i)   No gain or loss will be recognized for federal income tax
    purposes by BTC stockholders upon the exchange in the Merger of shares of
    BTC Common Stock solely for NBI Common Shares (except with respect to cash
    received in lieu of a fractional share interest in NBI Common Shares).

           (ii)  The basis of NBI Common Shares received in the Merger by BTC
    stockholders will be the same as the basis of the shares of BTC Common Stock
    surrendered in exchange therefor.

           (iii) The holding period of the NBI Common Shares received in the
    Merger by a BTC stockholder will include the holding period during which the
    shares of BTC Common Stock surrendered in exchange therefor were held by the
    BTC stockholder, provided such shares of NBI Common Stock were held as
    capital assets at the Merger Effective Date.

           (iv)  Cash received by a holder of BTC Common Stock in lieu of a
    fractional share interest in NBI Common Shares will be treated as received
    in exchange for such fractional share interest and, provided the fractional
    share would have constituted a capital asset in the hands of such holder,
    the holder will recognize a capital gain or loss in an amount equal to the
    difference between the amount of cash received and the portion of the
    adjusted tax basis in the BTC Common Stock allocable to the fractional share
    interest.

    The opinion of KPMG summarized above is based, among other things, on
assumptions relating to certain facts and circumstances of, and the intentions
of the parties to, the Merger, which assumptions have been made with the consent
of BTC and NBI.

    The exchange of BTC Common Stock for cash pursuant to the exercise of
dissenters' rights will be a taxable transaction. Holders of BTC Common Stock
electing to exercise dissenters' rights should consult their own tax advisers as
to the tax treatment in their particular circumstances. See "--Dissenters'
Rights."
    
    BTC will not recognize any gain or loss upon the receipt by it of the assets
of NBI Interim, when NBI Interim is merged with and into BTC, solely for shares
of NBI stock. NBI will not recognize any gain or loss upon the exchange of its
shares of NBI Interim stock solely in exchange for shares of BTC stock.      
    
    BECAUSE CERTAIN TAX CONSEQUENCES OF THE MERGER MAY VARY DEPENDING UPON THE
PARTICULAR CIRCUMSTANCES OF EACH STOCKHOLDER, EACH STOCKHOLDER OF BTC IS URGED
TO CONSULT SUCH HOLDER'S OWN TAX ADVISER TO DETERMINE THE PARTICULAR TAX
CONSEQUENCES TO SUCH HOLDER OF THE MERGER (INCLUDING THE APPLICATION AND EFFECT
OF STATE AND LOCAL INCOME AND OTHER TAX LAWS).      

Business Pending Consummation

    BTC and NBI have agreed in the Merger Agreement not to take certain actions
relating to their respective operations pending consummation of the Merger
without the prior approval of the other party, except as otherwise permitted in
the Merger Agreement. These actions include, without limitation: (i) paying any
dividends, other than common stock cash dividends consistent with past practice
and in an amount not greater than the last previous cash dividend paid prior to
execution of the Merger Agreement (provided, however, that BTC may, at its
option, accelerate the record and payment dates of its semi-annual cash
dividend, if any, which would regularly in accordance with past practice be
payable in January 1996 or July 1996, so that the record and payment dates of
the BTC January or July cash dividend, as the case may be, occur prior to the
Merger Effective Date if the Merger Effective Date will occur: (a) after the
record date of the second semi-annual NBI cash dividend, if any, for 1995 which
would regularly in accordance with past practices be payable in December 1995,
but prior to the BTC January cash dividend if it is not so accelerated, or (b)
after the record date of the first semi-annual NBI cash dividend, if any, for
1996, which would regularly in accordance with past practices be payable in June
1996 but prior to the BTC July cash dividend if it were not so accelerated);
(ii) redeeming or otherwise acquiring any shares of capital stock, or issuing
any

                                       38
<PAGE>
 
additional shares of its capital stock or giving any person the right to
acquire any such shares, or issuing any long-term debt; (iii) entering into any
employment agreements with, increasing the rate of compensation or paying any
bonus to, any director, officer or employee, except in accordance with plans or
agreements existing and as in effect on the date of the Merger Agreement and
previously disclosed; (iv) entering into or modifying any directors' or
employees' benefit plans; (v) disposing of or granting an encumbrance against
any material portion of assets or merging or consolidating with, or acquiring
any substantial portion of the business or property of, any other entity; or
(vi) taking any other action not in the ordinary course of business.
    
    The Merger Agreement requires the Board of Directors of BTC to (i) conform
BTC's Bylaws to those of NBI Interim by adopting the Bylaws of NBI Interim as
those of BTC and (ii) use its best efforts to modify and change the audit,
investment, litigation, real estate valuation and trust department policies and
practices (including loan classifications and levels of reserves) prior to the
Merger Effective Date so as to be consistent on a mutually satisfactory basis
with those of NBB and generally accepted accounting principles. There currently
are no anticipated modifications or changes in BTC's policies or practices which
will be required to conform with generally accepted accounting principles nor
are there currently any anticipated changes in BTC's loan classifications and
levels of reserves prior to the Effective Date of the Merger. BTC is not
required to modify or change any such Bylaws, policies or practices, however,
until (i) approval of the Proposal by the requisite vote of the BTC
stockholders; (ii) receipt of the Required Regulatory Approvals, and expiration
of any statutory waiting periods relating thereto; (iii) procurement of all
other regulatory consents and approvals and satisfaction of all other
requirements prescribed by law which are necessary to consummate the Merger;
(iv) such time as BTC and NBI shall reasonably agree that the Merger Effective
Date will occur prior to public disclosure of such modifications or changes in
regular periodic earnings releases or periodic reports filed with the FDIC; and
(v) such time as NBI acknowledges in writing that all conditions to NBI's
obligations to consummate the Merger (and NBI's rights to terminate the Merger
Agreement) have been waived or satisfied. BTC must, in all circumstances, make
such modifications and changes not later than immediately prior to the Merger
Effective Date. Such modifications and changes, once implemented, shall not
affect the Common Stock Exchange Ratio.      

Regulatory Approvals

    The Merger transaction described in this Prospectus/Proxy Statement is
subject to the prior approval by the FDIC, the Federal Reserve Board, the BFI
and the Virginia Commission, as required by applicable law. There can be no
assurance that the Required Regulatory Approvals will be obtained or as to the
timing or conditions thereof. Applications have been filed with each of such
regulatory authorities for approval of the Merger transaction.

Conditions to Consummation; Termination

    Consummation of the Merger is subject, among other things, to: (i) approval
of the Proposal by the requisite vote of the stockholders of BTC; (ii) receipt
of the Required Regulatory Approvals (see "--Regulatory Approvals" above)
without any restrictions or conditions which would so materially adversely
impact the economic or business benefits of the transactions contemplated by the
Merger Agreement so as to render inadvisable the consummation of the Merger;
(iii) there being in effect no order, decree or injunction of any court or
governmental or regulatory authority prohibiting the Merger; (iv) the
Registration Statement being effective and receipt of all required state
securities law approvals; (v) receipt of an opinion from KPMG to the effect that
the acquisition of BTC Common Stock by NBI and the Merger generally constitutes
a tax free reorganization under Section 368 under the Internal Revenue Code;
(vi) receipt by NBI and BTC of a letter, satisfactory to NBI and BTC, from KPMG
to the effect that the Merger will qualify for pooling-of-interests accounting
treatment; (vii) receipt by each party of an opinion from its financial adviser
that the terms of the Merger are fair to its stockholders from a financial point
of view; and (viii) receipt by each party of a letter from the other party's
independent certified public accountants to the effect that they are not aware
of any facts or circumstances relating to actions taken by such party or actions
that such party has failed to take that might cause the Merger not to qualify
for pooling-of-interests accounting treatment.

    Consummation of the Merger is also subject to the satisfaction or waiver of
various other conditions specified in the Merger Agreement, including, among
others: (i) the delivery by BTC and NBI, each to the other,

                                       39
<PAGE>
 
of opinions of their respective counsel and certificates executed by their
respective chief executive officers and chief financial officers as to
compliance with the Merger Agreement; (ii) as of the Merger Effective Date, the
accuracy of the representations and warranties, and compliance in all material
respects with the agreements and covenants, of the parties to the Merger
Agreement (except for such representations and warranties made as of an earlier
date, or as expressly contemplated by the Merger Agreement or, with respect to
certain representations and warranties, except for any inaccuracy that would not
exceed the materiality standard established for such representation or warranty
in the Merger Agreement); and (iii) the receipt by NBI and BTC of letters from

other party's financial position.

    The Merger Agreement provides that, whether before or after the Special
Meeting and notwithstanding the approval of the Proposal by the stockholders of
BTC, the Merger Agreement may be terminated and the Merger abandoned at any time
prior to the Merger Effective Date: (i) by mutual consent of the Boards of
Directors of NBI and BTC; or (ii) by either the Board of Directors of NBI or the
Board of Directors of BTC (a) in the event of a breach by the other party of any
representation or warranty contained in the Merger Agreement, which breach
exceeds the materiality standard established for termination of the Merger
Agreement and which cannot be or has not been cured after thirty days written
notice thereof is given to the party committing such breach; (b) in the event of
a material breach by the other party of any covenant or agreement contained in
the Merger Agreement that cannot be or has not been cured within thirty days
after the giving of written notice to the party committing such breach; (c) if
the Merger is not consummated on or before June 30, 1996; (d) if any Required
Regulatory Approval, to the extent necessary to consummate the Merger legally,
is finally and unconditionally denied or imposes any conditions or requirement
which would materially adversely impact the economic and business benefits of
the transactions contemplated by the Merger Agreement and the related Plan of
Merger so as to render inadvisable the consummation of the Merger; or (e) the
Board of Directors of NBI recommends to NBI stockholders approval of a sale of
all or substantially all of the assets of NBI or the merger or consolidation of
NBI with and into another entity with the effect that NBI will not be the
surviving corporation in such merger or consolidation.

Waiver; Amendment

    Prior to the Merger Effective Date, any provision of the Merger Agreement
may be: (i) waived by the party benefitted by the provision; or (ii) amended or
modified at any time (including the structure of the transaction), by an
agreement in writing among the parties thereto approved by their respective
Boards of Directors and executed in the same manner as the Merger Agreement,
except that, after approval by the stockholders of BTC, the consideration to be
received by the stockholders of BTC may not thereby be decreased.

Dissenters' Rights

    Holders of BTC Common Stock entitled to vote on approval of the Proposal
will be entitled to have the fair value of each such holder's shares of BTC
Common Stock immediately prior to the consummation of the Merger paid to such
holder in cash, together with interest, if any, by complying with the provisions
of Article 15 of the Virginia Act ("Article 15"). Under Article 15, the
determination of the fair value of a dissenter's shares would exclude any
appreciation or depreciation in the value of such shares in anticipation of the
Merger, unless such exclusion would be inequitable.

    A holder of BTC Common Stock who desires to exercise such holder's
dissenters' rights must satisfy all of the following conditions. A written
notice of such holder's intent to demand payment for such holder's BTC Common
Stock must be delivered to BTC before the taking of the vote on approval of the
Proposal. This written notice must be in addition to and separate from voting
against, abstaining from voting, or failing to vote on approval of the Proposal.
Voting against, abstaining from voting or failing to vote on approval of the
Proposal will not constitute written notice of an intent to demand payment
within the meaning of Article 15.

    A holder of BTC Common Stock electing to exercise such holder's dissenters'
rights under Article 15 must not vote for approval of the Proposal. Voting for
approval of the Proposal, or delivering a proxy in connection with the Special
Meeting (unless the proxy specifies a vote against, or abstaining from voting
on, approval of the

                                       40
<PAGE>
 
Proposal), will constitute a waiver of such holder's dissenters' rights and will
nullify any written notice of an intent to demand payment submitted by such
holder.

    A holder of record of BTC Common Stock may assert dissenters' rights as to
less than all of the shares registered in such holder's name only if such holder
dissents with respect to all shares beneficially owned by any one person and
notifies BTC in writing of the name and address of each person on whose behalf
such holder is asserting dissenters' rights. The rights of a partial dissenter
under Article 15 are determined as if the shares as to which the holder dissents
and the holder's other shares were registered in the names of different
stockholders.

    A beneficial holder of BTC Common Stock may assert dissenters' rights as to
shares held on such holder's behalf only if such holder: (i) submits to BTC the
record holder's written consent to the dissent not later than the time the
beneficial holder asserts dissenters' rights; and (ii) does so with respect to
all shares of which such holder is the beneficial holder or over which such
holder has the power to direct the vote.

    If the Merger is consummated, BTC will, within ten days after the Merger
Effective Date, deliver a dissenters' notice to all holders who satisfied the
foregoing requirements, which will: (i) state where payment demand is to be sent
and where and when certificates for Dissenting Shares are to be deposited; (ii)
supply a form for demanding payment that includes the date (August 29, 1995) of
the first announcement to news media of the terms of the Merger, and requires
that the person asserting dissenters' rights certify whether or not such person
acquired beneficial ownership of such person's Dissenting Shares before or after
such date; (iii) set a date by which BTC must receive the payment demand, which
date may not be less than thirty nor more than sixty days after the date of
delivery of the dissenters' notice; and (iv) be accompanied by a copy of Article
15.

    A stockholder sent a dissenters' notice shall demand payment, certify that
such holder acquired beneficial ownership of such holder's Dissenting Shares
before, on or after August 29, 1995, and deposit the certificates representing
such holder's Dissenting Shares in accordance with the dissenters' notice. A
stockholder who deposits such holder's shares as described in the dissenters'
notice retains all other rights as a holder of BTC Common Stock except to the
extent such rights are cancelled or modified by the consummation of the Merger.
A stockholder who does not demand payment and deposit his share certificates
where required, each by the date set forth in the dissenters' notice, is not
entitled to payment for such holder's shares under Article 15.

    Except as provided below with respect to after-acquired shares, within
thirty days after receipt of a payment demand, BTC shall pay the dissenter the
amount that BTC estimates to be the fair value of the dissenter's shares, plus
accrued interest. The obligation of BTC to make such payment may be enforced:
(i) by the Circuit Court for Tazewell County, Virginia; or (ii) at the election
of any dissenter residing or having its principal office in Virginia, by the
circuit court in the city or county where the dissenter resides or has such
office. The payment by BTC will be accompanied by: (i) BTC's balance sheet as of
the end of a fiscal year ended not more than sixteen months before the Merger
Effective Date, an income statement for that year, a statement of changes in
stockholders' equity for that year and the latest available interim financial
statements, if any; (ii) an explanation of how BTC estimated the fair value of
the Dissenting Shares and of how the interest was calculated; (iii) a statement
of the dissenter's right to demand payment as described below; and (iv) a copy
of Article 15.

    BTC may elect to withhold payment from a dissenter unless the dissenter was
the beneficial owner of the Dissenting Shares on August 29, 1995, in which case
BTC will estimate the fair value of such after-acquired shares, plus accrued
interest, and will offer to pay such amount to each dissenter who agrees to
accept it in full satisfaction of such dissenter's demand. BTC will send with
such offer an explanation of how it estimated the fair value of the shares and
of how the interest was calculated, and a statement of the dissenter's right to
demand payment as described below.

    Within thirty days after BTC makes or offers payment as described above, a
dissenter may notify BTC in writing of the dissenter's own estimate of the fair
value of the Dissenting Shares and the amount of interest due, and demand
payment of such estimate (less any payment by BTC) or reject BTC's offer and
demand payment of such estimate.

                                       41
<PAGE>
 
    If any such demand for payment remains unsettled, within sixty days after
receiving the payment demand BTC will petition the Circuit Court for Tazewell
County, Virginia to determine the fair value of the shares and the accrued
interest and make all dissenters whose demands remain unsettled parties to such
proceeding, or pay each dissenter whose demand remains unsettled the amount
demanded. Each dissenter made a party to such proceeding is entitled to a
judgment for: (i) the amount, if any, by which the court finds that the fair
value of the Dissenting Shares, plus interest, exceeds the amount paid by BTC;
or (ii) the fair value, plus accrued interest, of the dissenter's after-acquired
shares for which BTC elected to withhold payment. The court will determine all
costs of the proceeding, including the reasonable compensation and expenses of
appraisers appointed by the court and assess the costs against BTC, or against
all or some of the dissenters to the extent the court finds the dissenters did
not act in good faith in demanding payment.

    The foregoing is only a summary of the rights of a dissenting holder of BTC
Common Stock. Any holder of BTC Common Stock who intends to dissent from the
Merger should carefully review the text of the applicable provisions of the
Virginia Act set forth in Attachment D to this Prospectus/Proxy Statement and
should also consult with such holder's attorney. The failure of a holder of BTC
Common Stock to follow precisely the procedures summarized above, and set forth
in Attachment D, may result in loss of dissenters' rights. No further notice of
the events giving rise to dissenters' rights or any steps associated therewith
will be furnished to holders of BTC Common Stock, except as indicated above or
otherwise required by law.

    In general, any dissenting stockholder who perfects such holder's right to
be paid the fair value of such holder's BTC Common Stock in cash will recognize
taxable gain or loss for federal income tax purposes upon receipt of such cash.
See "--Certain Federal Income Tax Consequences."

    Consummation of the Merger is conditioned upon the Merger being accounted
for on a pooling-of-interests basis. If the number of Dissenting Shares is
sufficiently large, accounting rules may preclude the Merger as being accounted
for on a pooling-of-interests basis. See "--Accounting Treatment" and "--
Conditions to Consummation; Termination."

Accounting Treatment
    
    Consummation of the Merger is conditioned upon the Merger being accounted
for on a pooling-of-interests accounting basis and the receipt at closing of NBI
and BTC of a letter from KPMG, dated as of the Merger Effective Date, with
respect thereto. See "--Conditions to Consummation; Termination." Under this
accounting treatment, as of the Merger Effective Date the assets and liabilities
of BTC would be added to those of NBI at their recorded book values and the
stockholders' equity accounts of BTC and NBI would be combined on NBI's
consolidated balance sheet. On a pooling-of-interests accounting basis, income
and other financial statements of NBI issued after consummation of the Merger
would be restated retroactively to reflect the consolidated combined financial
position and results of operations of NBI and BTC as if the Merger had taken
place prior to the periods covered by such financial statements.      

Expenses

    All expenses incurred by or on behalf of the parties in connection with the
Merger Agreement and the transactions contemplated thereby will be borne by the
party incurring the same, except (i) that printing expenses for this
Prospectus/Proxy Statement will be shared equally by NBI and BTC and (ii) in the
circumstances below.

    In the event that the Merger Agreement is terminated otherwise than on
account of a breach by NBI or because NBI recommends to NBI stockholders
approval of a sale of all or substantially all of the assets of NBI or the
merger or consolidation of NBI with or into another entity with the effect that
NBI will not be the surviving corporation in such merger or consolidation 
(see "--Conditions to Consummation; Termination"), the total documented 
out-of-pocket costs, expenses and fees incurred by BTC and NBI in connection
with and arising out of the Merger and the other transactions contemplated by
the Merger Agreement (including, without limitation, amounts

                                       42
<PAGE>
 
paid or payable to investment bankers, to counsel and accountants and to
governmental and regulatory agencies) shall be aggregated, and each party shall
be responsible for paying one-half of the same.

    To compensate NBI or BTC, as the case may be, for entering into the Merger
Agreement, taking action to consummate the transactions contemplated thereunder
and incurring the costs and expenses relating thereto, including, but not
limited to, the forgoing of other opportunities and other damages which would be
sustained but also would be difficult to ascertain if the following events
occur, NBI or BTC, as the case may be (the "Subject Party"), will pay the other
party unconditionally and absolutely the sum of $2,500,000 as the other party's
exclusive remedy if, prior to the termination of the Merger Agreement, any of
the following shall occur: (i) without the consent of the other party, the
Subject Party shall have entered into an agreement to effect (a) a merger,
consolidation or similar transaction involving the Subject Party or any of its
significant subsidiaries, (b) the disposition, by sale, lease, exchange or
otherwise, of assets of the Subject Party or any of its significant subsidiaries
representing in either case 25% or more of the consolidated assets or deposits
of the Subject Party and its subsidiaries, or (c) the issuance, sale or other
disposition by the Subject Party of (including by way of merger, consolidation,
share exchange or any similar transaction) securities representing 25% or more
of the voting power of the Subject Party or any of its significant subsidiaries
(each of (a), (b) or (c), an "Acquisition Transaction"); or (ii) any person
shall have acquired beneficial ownership of, or the right to acquire beneficial
ownership of, or any group has been formed which beneficially owns or has the
right to acquire ownership of, 20% or more of the voting power of the Subject
Party or any of its significant subsidiaries and, within one year from
termination of the Merger Agreement, the Subject Party enters into Acquisition
Transaction with such person or group, as the case may be.

Market Prices
    
    The common stock of each of NBI and BTC is traded on a very limited basis in
the over-the-counter market and is not listed on any exchange or quoted on
Nasdaq. Trading of NBI common stock and BTC Common Stock is presently reflected
in the Over-the-Counter Electronic Bulletin Board of the NASD. As of 
December 31, 1995, there were 688 holders of record of NBI Common Stock and 475
holders of record of BTC Common Stock.      

    The following is a summary of the market price per share of the common stock
of NBI and BTC for 1993, 1994 and 1995, respectively. Prices do not necessarily
reflect the prices which would have prevailed had their been an active trading
market, nor do they reflect unreported trades, which may have been at lower or
higher prices.

    On August 28, 1995, the last business day prior to public announcement of
the execution of the Merger Agreement, the last known sales price per share of
NBI common stock was $25.00. There were no known sales of BTC Common Stock on
August 28, 1995. The last known sales price of BTC Common Stock prior to August
28, 1995, was $15.00 on July 6, 1995. There were no known sales of NBI or BTC
common stock on August 29, 1995, the day such announcement was made. On August
30, 1995, the day after announcement of the execution of the Merger Agreement,
the last known sales price of NBI common stock was $24.50. There were no known
sales of BTC Common Stock on August 30, 1995. The last known sales price of NBI
common stock was $25.25 on February 21, 1996, and the last known sales price of
BTC Common Stock was $21.50 on or about February 2, 1996.      

    NBI has agreed that it will use its best efforts, after consummation of the
Merger, to cause the NBI common stock, including, but not limited to, the NBI
Common Shares to be issued to holders of shares of BTC Common Stock in
connection with consummation of the Merger, to be listed on Nasdaq. The Nasdaq
listing criteria require NBI to, among other things, satisfy certain minimum
requirements with respect to its total assets, capital and surplus, the number
of holders of record of NBI common stock, the number of shares of NBI common
stock outstanding and its market value in the trading market for the common
stock. NBI believes that it currently meets the Nasdaq listing requirements;
however, there can be no assurance whether or when the NBI common stock will be
accepted for listing nor of the effect that such listing, if accomplished, would
have on the trading market for NBI's common stock.

    paid on December 1, 1995, adjusted for the 0.11129 per share NBI Stock Split
    to be declared and issued just prior to the Merger, would be $.57. On an
    equivalent pro forma basis, such current annual NBI dividend per BTC Common
    Share would be $.57, based on the Common Stock Exchange Ratio. Future NBI
    and BTC dividends are dependent upon their respective earnings and financial
    conditions, government regulations and policies and other factors.      

       NBI's primary source of funds for dividend payments is dividends from
NBB. Under applicable federal laws, the Comptroller of the Currency restricts
the total dividend payments of NBB, as more fully discussed below. See "CERTAIN
REGULATORY CONSIDERATIONS--NBB and BTC--Limits on Dividends and Other Payments,"
"DESCRIPTION OF NBI CAPITAL STOCK" and "CERTAIN DIFFERENCES IN THE RIGHTS OF BTC
AND NBI STOCKHOLDERS--Dividends and Other Distributions."

BTC Charter Amendment

       As part of the Merger transaction, the BTC Board of Directors has
recommended that its stockholders approve the BTC Charter Amendment, which would
amend the Articles of Incorporation ("Articles") of BTC to (i) eliminate the
preemptive rights of holders of shares of BTC Common Stock; (ii) conform the
Articles of BTC precisely to the provisions of the Articles of NBI Interim
relating to the limitation of liability and indemnification of BTC directors and
officers and the number of directors constituting the Board of Directors of BTC,
respectively;

                                       45
<PAGE>
 
and (iii) eliminate existing provisions of BTC's Articles with
respect to the issuance of shares of BTC Common Stock by the Board and repeal
any other provisions which are contrary, inconsistent or similar to (ii) above.
The amendments are intended to facilitate the Merger transaction and integrate
BTC into NBI's holding company structure.

    The form of the BTC Charter Amendment is attached to this Prospectus/Proxy
Statement as Attachment B. In addition to the changes described below, the BTC
Charter Amendment modifies the format of the current BTC Articles and deletes
the provisions in the current BTC Articles establishing the initial Board of
Directors. The description of the BTC Charter Amendment set forth herein is
qualified in its entirety by reference to Attachment B.

    Elimination of Preemptive Rights

    Pursuant to Virginia law, each stockholder of BTC presently has a preemptive
right to purchase a percentage of the authorized but unissued Common Stock of
BTC, upon the Board of Directors' decision to issue additional shares (excluding
directors' qualifying shares), equal to such stockholder's then current
percentage ownership of the total outstanding shares of BTC Common Stock, before
any such shares can be offered to other parties. These statutory preemptive
rights do not extend to (i) shares issued to officers or employees of BTC
pursuant to a plan approved by stockholders, or (ii) shares sold other than for
money. The Board of Directors believes that the best interests of BTC will be
served by amending the BTC Articles to delete the preemptive rights of
stockholders and thereby facilitate the Merger. Further, upon consummation of
the Merger, preemptive rights will no longer serve a purpose because BTC will be
a wholly owned subsidiary of NBI, and NBI therefore will be its sole
stockholder. The text of the proposed amendment is set out in Attachment B
hereto.

    Number of Directors and Filling of Vacancies
    
    BTC's current Articles establish that the number of directors constituting
the Board of Directors shall be not less than five and shall be fixed in the
Bylaws of BTC, or, if not fixed in the Bylaws shall be twenty-five. The BTC
Charter Amendment modifies this provision by providing that the Board of
Directors shall consist of not less than five nor more than twenty-five
stockholders of BTC or its holding company, with the exact number being fixed
and determined from time to time by resolution of a majority of the full Board
of Directors or by resolution of the stockholders at any annual or special
meeting of BTC. The BTC Charter Amendment further expressly provides that each
director is required to own at least the amount of capital stock in BTC or in a
bank holding company controlling BTC as may be required by law. If the Merger is
consummated, each BTC director is required under Virginia law to be the owner in
his sole name and have in his personal possession or control shares of NBI
common stock having a book value of not less than $5,000, calculated as of the
last business day of the calendar year preceding his election or reelection as a
director.      

    Upon consummation of the Merger, BTC will be a wholly owned subsidiary of
NBI. This amendment permits NBI, as the sole stockholder of BTC, to determine,
subject to certain restrictions (see "--Management and Operations of NBI and BTC
after the Merger"), the number of directors who will serve on the BTC Board and
requires that such directors be stockholders of NBI.

    Currently, unless otherwise provided in the Articles, newly created
directorships and vacancies on the BTC Board of Directors may be filled by a
plurality vote of the stockholders or a majority vote of the remaining
directors. The BTC Charter Amendment provides that any vacancy on the Board of
Directors of BTC occurring during the course of the year may be filled by an
action of the Board of Directors. Directors so elected by the Board would, under
Virginia law, hold office until the next stockholders' meeting at which
directors are elected, when they will be subject to reelection by stockholders.

    Proposed Liability Limitations of Directors and Officers

    Section 13.1-692.1 of the Virginia Act limits the amount of monetary damages
which may be assessed against a director or officer of a Virginia corporation in
a direct or derivative action brought by stockholders.

                                       46
<PAGE>
 
Section 13.1-692.1 provides that damages assessed against a director or officer
arising out of a single transaction, occurrence or course of conduct shall not
exceed the lesser of: (i) the amount specified in the Articles or a stockholder-
adopted Bylaw as a limitation on or elimination of liability of the director or
officer; or (ii) the greater of (a) $100,000 or (b) the amount of cash
compensation received by the director or officer from the corporation during the
twelve months immediately preceding the act or omission giving rise to
liability. This statutory limit on damages does not apply in the event of
willful misconduct or a knowing violation of the criminal law or of any federal
or state securities law. The statute does not distinguish between liabilities
based upon the fiduciary duties of care and loyalty.

    BTC's present Articles contain a provision eliminating the liability of
directors and officers of BTC, except in cases in which a director or officer
engaged in willful misconduct or a knowing violation of the criminal law or of
any federal or state securities law. The BTC Charter Amendment, in contemplation
of the Merger, deletes this provision. Accordingly, under the Virginia Act, the
liability of a director or officer of BTC for monetary damages would be the
greater of $100,000 or the amount of compensation received by the director in
the twelve months preceding the act or omission giving rise to the liability.

    Proposed Indemnification Provisions
    

    Section 13.1-704 of the Virginia Act permits a Virginia corporation to
indemnify its directors and officers except for liability arising out of their
willful misconduct or knowing violation of the criminal law.

    BTC's current Articles require indemnification of a director or officer of
BTC against liabilities, judgments, fines, penalties and claims which may be
asserted against or incurred by him or her in connection with any threatened,
actual, pending or appealed action, suit or proceeding to which he or she may be
made a party by reason of his or her being or having been a director or officer
of BTC, except for amounts (i) actually paid by BTC pursuant to a settlement
agreement or in satisfaction of a judgment arising out of litigation that was
brought by or in the right of BTC, or (ii) where he or she was finally adjudged
to be liable by reason of gross negligence, or willful misconduct or criminal
conduct in the performance of his or her duties. Any reasonable costs or
expenses actually incurred in connection with a claim may be advanced to a
director or officer prior to final disposition of the matter provided that
certain standards of conduct have been satisfied and an appropriate written
agreement has been executed by the director or officer. Under the current
Articles, BTC may choose to indemnify existing and former employees as it deems
appropriate and their heirs, executors and administrators.

    The BTC Charter Amendment would require indemnification of any director or
officer who is a party to any proceeding instituted against him or her by third
parties or by or on behalf of BTC itself by reason of the fact that he or she is
or was a director or officer of BTC, or served as a director, officer, employee
or agent of another corporation or other entity at the request of BTC, against
any liabilities incurred by him or her in connection with such proceeding,
unless his or her acts or omissions constitute willful misconduct or a knowing
violation of the criminal law. The BTC Charter Amendment provides that the Board
of Directors, by majority vote of a quorum of disinterested directors, may
contract in advance to provide such indemnification, but the Board has no
present plans to do so. The principal changes that would be effected by the
indemnification provisions of the BTC Charter Amendment include, (i) absent
willful misconduct or a knowing violation of the criminal law, requiring BTC to
provide indemnification of amounts actually paid to BTC pursuant to a settlement
agreement or in satisfaction of a judgment arising out of litigation that was
brought by or in the right of BTC; (ii) establishing an express procedure for
determining whether indemnification is permissible; and (iii) requiring BTC to
provide indemnification for liability arising out of gross negligence.

    Under paragraph (5) of the BTC Charter Amendment, the determination of
whether indemnification is permissible will be made (i) by a majority vote of a
quorum consisting of disinterested directors; (ii) if such quorum is not
available, by a majority vote of a committee duly designated by the Board of
Directors consisting solely of two or more disinterested directors; or (iii) by
special legal counsel selected by (a) the Board or its committee in the manner
prescribed in (i) or (ii) above, or (b) if a quorum of the Board cannot be
obtained under (i) and a committee cannot be designated under (ii), selected by
majority vote of the full Board (in which selection directors who are

                                       47
<PAGE>
 
parties may participate), or (iii) by the stockholders, but shares owned by or
voted under the control of directors who are at the time parties to the
proceeding may not be voted on the determination. Notwithstanding the foregoing,
in the event there has been a change in the composition of a majority of the
Board after the date of the alleged act or omission with respect to which
indemnification is claimed, any determination and advancement of expenses with
respect to any claim for indemnification shall be made by special legal counsel
agreed upon by the Board of Directors and the applicant.

    Paragraph (6) of the BTC Charter Amendment provides that, to the extent
permitted by applicable banking laws and regulations, BTC shall pay for or
reimburse the reasonable expenses incurred by any applicant who is a party to a
proceeding in advance of final disposition of the proceeding or the making of
any determination on indemnification if the following conditions are met (i) the
Board, in good faith, determines in writing that (a) the director has a
substantial likelihood of prevailing on the merits; (b) in the event the
director does not prevail, he or she will have the financial capability to
reimburse BTC; and (c) payment of expenses by BTC will not adversely affect
BTC's safety and soundness. To the extent required by applicable banking laws
and regulations, if at any time the BTC Board of Directors believes that either
conditions (a), (b), or (c) are no longer met, BTC shall cease paying such
expenses or premiums. The Board shall enter into a written agreement with the
director, specifying the conditions under which he or she will be required to
reimburse BTC, which agreement shall require reimbursement for expenses already
paid, if and to the extent the Board finds that the director willfully
misrepresented factors relevant to the Board's determination of conditions (a)
or (b), or if a final decision accessing penalties or requiring payments is
returned. BTC shall insure that it complies with all applicable laws and
regulations affecting loans to directors, officers and employees, in the event
reimbursement is required. Additionally, the applicant must furnish BTC (a) a
written statement of his or her good faith belief that he or she has met the
standard of conduct to receive indemnification; and (b) a written undertaking,
executed personally or on his or her behalf, to repay the advance if it is
ultimately determined that he or she did not meet such standard of conduct.

    Paragraph (7) of the BTC Charter Amendment authorizes BTC, by a majority
vote of a quorum of disinterested directors, to provide indemnification to other
persons, including directors and officers of BTC's subsidiaries and employees
and agents of BTC and its subsidiaries, to the same extent as if such person was
a director or officer of BTC. BTC may, by a majority vote of a quorum of
disinterested directors, also contract in advance to provide such
indemnification, but has no present plans to do so. Whether stockholders would
be estopped from a claim that any such contract, or any contract with regard to
indemnity of directors or officers, is invalid or unenforceable due to the
approval of the BTC Charter Amendment would depend upon the facts and
circumstances relating to such claim.

    Paragraph (8) of the BTC Charter Amendment authorizes BTC to purchase and
maintain insurance to indemnify it against all or part of the liability assumed
by it in accordance with the BTC Charter Amendment. Paragraph (8) further
authorizes BTC to purchase insurance for any director, officer, employee or
agent of another corporation or other entity who is serving at the request of
BTC, whether or not BTC would have the power to indemnify him against such
liability under the BTC Charter Amendment.

    Scope and Application of the BTC Charter Amendment
    

    Paragraph (11) of the BTC Charter Amendment provides that the BTC Charter
Amendment shall be applicable to only to conduct, actions or omissions of any
applicant occurring or arising after the Effective Date of the Merger.

    Under the Merger Agreement, NBI has agreed that, for six years following the
Merger Effective Date, it will cause BTC to indemnify any person who has rights
to indemnification pursuant to BTC's Articles as in effect on the date of the
Merger Agreement, to the extent legally permitted to do so. With respect to
matters occurring on or prior to the Merger Effective Date, the adoption of the
BTC Charter Amendment will not affect any person's right, if any, to such
indemnification. See "--Interests of Certain Persons."

    Other Effects of the BTC Charter Amendment

    The approval of the Merger, the related Plan of Merger and the BTC Charter
Amendment could, as a result of the BTC Charter Amendment, increase the costs to
NBI in the future in the event that claims for indemnification were to be
asserted. All directors and officers of BTC will have an interest in and could
benefit from the provisions of the BTC Charter Amendment at the potential
expense of NBI's stockholders. The Board of Directors of NBI believes that the
foregoing risks are outweighed by the positive effect that the provisions will
have, namely, the enhancement of BTC's ability to attract and retain qualified
directors and officers, and that the provisions ultimately will inure to the
benefit of BTC, NBI and NBI's stockholders.

    Insofar as indemnification for liability arising under federal securities
laws may be permitted to directors, officers and other persons pursuant to the
BTC Charter Amendment, BTC understands that it is the position of the Commission
that such indemnification is void as against public policy and unenforceable.
    
NBI Stock Split      
    
    NBI will, prior to the Merger Effective Date, increase the number of shares
of NBI common stock issued and outstanding by means of a stock split effected in
the form of a stock dividend totaling 190,768 shares of NBI common stock;
provided, however, that NBI shall not be required to declare such stock split
until (i) approval of the Proposal by the requisite vote of BTC stockholders;
(ii) receipt of the Required Regulatory Approvals and expiration of any
statutory waiting periods relating thereto; and (iii) such time as BTC
acknowledges in writing that all conditions to its obligations to consummate the
Merger (and BTC's right to terminate the Merger Agreement) have been waived or
satisfied. The Common Stock Exchange Ratio takes into account the NBI Stock
Split.

                    NOTES TO PRO FORMA FINANCIAL INFORMATION

(1)  The pro forma information presented is not necessarily indicative of
     the results of operations or the combined financial position that would
     have resulted had the Merger been consummated at the beginning of the
     periods indicated, nor is it necessarily indicative of the results of
     operations in future periods or the future financial position of the
     combined entities.
    
(2)  It is assumed the Merger will be accounted for on a pooling-of-interests 
     accounting basis and, accordingly, the related pro forma adjustments herein
     reflect the exchange of one share of common stock of NBI for one share of
     common stock of BTC. It is also assumed that NBI will issue the NBI shares
     resulting from the NBI Stock Split of 0.11129 per share effected in the
     form of a stock dividend to the holders of NBI common stock just prior to
     the Merger Effective Date to facilitate the one-for-one Common Stock
     Exchange Ratio.      

                                       51
<PAGE>
     
(3)  Stockholders' equity was adjusted for the Merger by the (i) addition of
     1,888,209 shares of NBI common stock of $2.50 par value amounting to
     $4,720,522; (ii) elimination of 1,888,209 shares of BTC common stock of
     $1.00 par value amounting to $1,888,209; and (iii) recordation of the
     remaining amount of $2,832,313 as a decrease in surplus ($2,710,313) and
     undivided profits ($122,000) at September 30, 1995.      
    
(4)  Stockholders' equity was also adjusted to reflect the NBI Stock Split
     of 0.11129 per share by (i) increasing NBI common stock $476,920; and
     (ii) decreasing surplus $476,920 the par value of the stock ($2.50 per
     share) at September 30, 1995.      

(5) NBI Interim has been formed to facilitate the Merger. NBI has subscribed to
     2,000 shares of common stock ($1.00 par value) of NBI Interim for
     $4,000,000 ($2,000,000 in common stock and $2,000,000 in surplus), and this
     subscription is represented by a stock subscription receivable from NBI
     (parent company only). The pro forma balance sheet adjustments do not
     reflect the stock subscription receivable of $4,000,000 and the
     simultaneous elimination of same to arrive at pro forma combined.
    
(6)  Pro forma income per common share data has been computed based on the
     combined historical income before cumulative effect of change in
     accounting principle of NBI and BTC using the historical weighted average
     shares outstanding of NBI common stock giving effect to the 0.11129 per
     share NBI Stock Split (see note 7) and the historical weighted average
     outstanding shares of BTC common stock, adjusted to equivalent shares of
     NBI common stock, as of the earliest period presented.      
    
(7)  Pro forma NBI income per common share data adjusted for stock split
     has been computed giving effect to the NBI Stock Split of 0.11129 per
     share effected in the form of a stock dividend to be declared and issued
     pro rata to holders of NBI common stock just prior to the Merger Effective
     Date to facilitate the one-for-one Common Stock Exchange Ratio.      

(8)  Certain reclassifications have been included herein to conform
     statement presentations.  There are no intercompany transactions between
     NBI and BTC, and therefore no intercompany eliminations are required.
    
(9)  The unaudited pro forma financial information does not include any material
     expenses related to the Merger. Estimated expenses related to the Merger of
     $300,000 are expected to be incurred after September 30, 1995.     
    
(10) As indicated by the foregoing unaudited pro forma financial
     information and based solely on combined financial information as of
     September 30, 1995, upon consummation of the Merger, NBI's historical
     income before cumulative effect of change in accounting principle per
     common share for the year ended December 31, 1994, and for the nine months
     ended September 30, 1995, adjusted for the NBI Stock Split (see note 2),
     would have been diluted 8.5 percent and 12.5 percent, respectively.  At
     September 30, 1995, BTC's historical book value per share would have been
     diluted by 6%.  It should not necessarily be assumed, however, that the
     foregoing data will represent actual dilution upon consummation of the
     Merger.

History and Business

     NBI is a bank holding company organized under the laws of Virginia in 1986
and registered under the BHCA. NBI conducts its operations through its sole
wholly owned subsidiary, NBB, which was originally chartered in 1891. NBB
operates a full-service banking business from its headquarters in Blacksburg,
Virginia, and its six area branch offices. NBB offers general retail and
commercial banking services to individuals, businesses, local government units
and institutional customers. These products and services include accepting
deposits in the form of checking accounts, money market deposit accounts, NOW
accounts, savings accounts and time deposits; making real estate, commercial,
revolving, consumer and agricultural loans; offering letters of credit;
providing other consumer financial services, such as automatic funds transfer,
collection, night depository, safe deposit, money order, travelers check,
savings bond sales and utility payment services; and providing other
miscellaneous services normally offered by commercial banks. NBB also conducts a
general trust business in Blacksburg near its headquarters location. Through its
trust operations, NBB offers a variety of fiduciary, personal and corporate
trust services.
    
     NBB makes loans in all major loan categories, including commercial,
commercial and residential real estate, construction and consumer loans.      
    
Commercial Loans      
    
     Loans are made to businesses and individuals for business purposes on both
secured and unsecured bases. NBB's loan policies normally require commercial
loan requests to be accompanied by complete documentation of income, by income
tax returns and by a full credit history.      
    
     Unsecured commercial loans must be supported by a satisfactory balance
sheet and income statement. The source of repayment and applicable secondary
repayment sources are identified in evaluating the loan request and must be
clear before the loan is closed. Short-term unsecured loans are usually for a
term of ninety-days or less and are repayable from a definite source. Other
unsecured commercial loans may be placed on a demand basis if the source of
repayment is known but the timing is unknown.      
    
     Commercial lines of credit may be secured or unsecured. They are generally
granted with the requirements of an annual review and the further requirement
that they be fully paid for a continuous thirty-day period during the twelve-
month term of the line of credit.      
    
     Business loans made on a secured basis may be secured by a security
interest in marketable equipment, accounts receivable, business equipment and/or
general intangibles of the business. In addition, or in the alternative, the
loan may be secured by a deed of trust lien on business real estate. Secured
commercial loans made for the purpose of financing working capital needs or for
equipment typically carry terms of from five to seven years. Deed of trust loans
may extend up to twenty-five years, although twenty years or less is a preferred
term. Prior to committing to make any such loan, the request is evaluated based
on the cash flow of the business entity involved. Commercial loans which are
secured by real estate are controlled by a specific NBB loan policy which states
that the cash flow coverage ratio from the project should be no less than 1.1 to
1.0. If the ratio is not achieved but the borrower has a well-documented
secondary source of repayment, the loan may still be considered. Regardless of
the value of collateral or the strength of any guarantors, it is NBB's policy to
require the business to exhibit sufficient cash flow to service the debt.
Liquidation of collateral or the strength of a guarantor serves as a secondary
source of repayment.     
    
     Commercial real estate loans in excess of $50,000 require a market
appraisal from an independent appraiser, unless that requirement is formally
waived by NBB's Board of Directors or its internal Loan Committee. Other
standard underwriting criteria include property surveys, title search and proper
title insurance and hazard insurance which insures NBB's interest in the real
estate. The loan to value ratio may vary, but it generally does not exceed 80%
without approval by the internal Loan Committee.      

                                       53
<PAGE>
 
    
     In some instances, when small business loans do not meet NBB's normal
underwriting criteria, in order to be able to grant the credit NBB will work
with the borrower and the Small Business Administration ("SBA") to obtain an SBA
guarantee of all or a portion of the loan amount.      
    
     The risks associated with commercial loans are related to the strength of
the individual business, the value of loan collateral and the general health of
the economy.      
    
Residential Real Estate Loans      
    
     Loans which are secured by residential real estate generally are subject to
the same underwriting criteria as commercial real estate loans. However, if a
residential mortgage loan exceeds 80% of the appraised value of the property,
private mortgage insurance is generally required. The creditworthiness of the
borrower, his or her total outstanding indebtedness, sources of income and the
value and marketability of the real estate are all factors which are evaluated.
Standard underwriting ratios of 28% mortgage debt to gross income and 36% total
debt to gross income are applied. Senior lending officers may approve exceptions
to these ratios if other factors are present. Residential real estate loans may
have a term of up to thirty years.     
    
     NBB participates in insured loan programs sponsored by the Department of
Housing and Urban Development, the Veterans Administration and the Virginia
Housing Development Authority. Each of these programs contains specific
requirements and restrictions, in addition to NBB's general loan application and
underwriting requirements.      
    
     It is NBB's policy to attempt to sell all residential real estate loans in
the secondary market on a servicing released basis. There are occasions when a
borrower or the real estate do not qualify under secondary market criteria, but
the loan request represents a reasonable credit risk. Also, an otherwise
qualified borrower may not want to have their real estate loan sold. When these
occasions arise, if the loans meet NBB's internal underwriting criteria, the
loan will be closed and placed in the NBB's portfolio.     
    
     Residential real estate loans carry risks associated with the continued
creditworthiness of the borrower and the value of the collateral.      
    
Construction Loans      
    
     Construction loans are made to financially responsible individuals or
businesses who have contracted for construction of structures. The loans are
secured by a first lien on the real estate improvements. NBB's loan policy is
that the loan to value ratio is not to exceed 80% of the lower of the cost or
appraisal value. In addition, a firm commitment for permanent financing or a
satisfactory prequalification for a permanent loan must be in place.      
    
     Construction loans are subject to the same general underwriting criteria as
commercial and residential real estate loans. All construction loans also are
made with the requirement that title insurance provides affirmative lien waiver
coverage. Construction draws are made in accordance with NBB's inspection
schedule or, for larger commercial projects, after architects's certification.
The normal loan term for residential projects is six to twelve months, and most
commercial projects do not exceed eighteen months.      
    
     In addition to the risks associated with all real estate loans,
construction loans bear the risks that the project will not be finished
according to schedule, the project will not be finished according to budget and
the value of the collateral at any point in time may be less than the principal
amount of the loan. In order to reduce risks associated with this type of loan,
NBB does not allow development costs, such as surveys and architect's fees, to
be made a part of the loan amount. Loans for commercial office or multi-unit
residential properties (eight units or more) will not usually be considered
until 50% of the space is pre-leased. Finally, NBB deals only with experienced
contractors who are known to NBB and who have sufficient financial strength to
complete the construction project.      

                                       54
<PAGE>
 
    
Consumer Loans      
    
     NBB places emphasis on loans to consumers.  A complete loan application, a
credit report and, if the principal amount is above $5,000, a recent personal
financial statement are required for each loan. Loan officers also evaluate the
character of the individual borrower. In considering a consumer loan request,
NBB has established the criteria that the borrower's total monthly debt
payments, including the loan for which application is being made, should not
exceed 36% of gross monthly income or 50% of net monthly income. Although
exceptions may be approved by senior lenders or the internal Loan Committee, the
maximum term for different types of loans include: vehicles - five years; mobile
homes -twelve years; second mortgage - fifteen years; equity line - ten years;
and property improvement- five years.      
    
     Loans used to purchase vehicles or other specific personal property and
loans associated with real estate are usually secured with a lien on the subject
vehicle or property. Consumer loans may also be granted on an unsecured basis,
if the customer's income and credit history are deemed to support the extension
of credit. Most consumer loans are monthly payment loans, although a single
payment loan may be made when there is an identified definite source of
repayment.      
    
     Negative changes in a customer's financial circumstances due to a large
number of factors, such as illness or loss of employment, can place the
repayment of a consumer loan at risk. In addition, deterioration in collateral
value can add risk to consumer loans.      
    
     NBB also originates a small number of student loans which are sold to the
Student Loan Marketing Association ("SLMA") when the individual student is no
longer enrolled as a full-time student at a qualifying college or university.
        
     Apart from selling residential mortgage loans in the secondary market and
selling student loans to SLMA, NBB will occasionally buy or sell all or a
portion of a loan for various other reasons. NBB will consider selling a loan,
or a participation in a loan, if: (i) the full amount of the loan would exceed
NBB's legal lending limit to a single borrower; (ii) the full amount of the
loan, when combined with a borrower's previously outstanding loans, would exceed
NBB's legal lending limit to a single borrower; (iii) the Board of Directors or
the internal Loan Committee believes that a particular borrower has a sufficient
level of debt at NBB; (iv) the borrower requests the sale; (v) NBB's loan to
deposit ratio is close to the upper limit set forth by NBB policy; and/or (vi)
the loan may create too great a concentration of NBB's loans in one particular
location or in one particular type of loan.     
    
     NBB will consider purchasing a loan, or a participation in a loan, from
another financial institution if the loan meets all applicable credit quality
standards and (i) the loan to deposit ratio is at a level where additional loans
would be desirable; and (ii) a common customer requests the purchase.     

     The following table sets forth, for the three fiscal years ended December
31, 1994 and for the nine months ended September 30, 1995 and 1994, the
percentage of total operating revenue contributed by each class of similar
services which contributed 15% or more of total operating revenues of NBB during
such periods.

     NBI believes that there is no single loan account, group of related loan
accounts, single deposit account, or group of related deposit accounts, the
withdrawal of which would have a material adverse effect on NBB's business. On
December 31, 1995, NBI had total consolidated assets of approximately $203
million and trust assets with a market value of approximately $64 million under
management or administration. As of that date, NBI had approximately $123
million in consolidated net loans, approximately $180 million in consolidated
deposits and approximately $23 million in consolidated stockholders' equity. 
     
     NBI's management will consider strategic acquisition opportunities in
businesses which complement or expand NBI's current operations. NBI currently
has no specific acquisition plans, other than the affiliation with BTC, and
there can be no assurance that any acquisitions will be made or what the terms
of such acquisitions, if any, may be.
    
Market Area      
    
     NBB's primary service area consists of the northern portion of Montgomery
County and all of Giles County, Virginia. This area includes the towns of
Blacksburg and Christiansburg in Montgomery County and the towns of Pearisburg
and Pembroke in Giles County. The local economy is diverse and is oriented
toward higher education, retail and service, light manufacturing and
agriculture. For the years 1994, 1993 and 1992, the unemployment rate in
Montgomery County was 3.2%, 4.85% and 8.30%, respectively, and the rate in Giles
County during those years was 7.40%, 10.41% and 7.13%, respectively. In 1995,
the rate for Montgomery County dropped to 3.0%, and the Giles County
unemployment rate increased to 8.4%. Montgomery County's largest employer is
Virginia Polytechnic Institute and State University ("VPI & SU") located in
Blacksburg. VPI & SU is the Commonwealth's land grant college and also its
largest university. Employment at VPI & SU has remained stable over the past
three years, and it is not expected to change materially in the next few years.
A second state supported university, Radford University, is located on the
western edge of the NBI's service area. It too has provided stable employment
opportunities in the region.      
    
     One of the area's major employers, the Radford Army Ammunition Plant (the
"RAAP"), has experienced significant layoffs since the early 1990s, with
employment there dropping from a high of approximately 3,800 to approximately
1,200 employees. These layoffs have had no significant impact on NBI's business,
although they did contribute to the area's relatively high unemployment rate in
the early 1990s. It is possible that employment levels at the RAAP will continue
to decline, but the local area has already absorbed the major impact of layoffs
at that facility. Giles County's primary employer is a Hoechst-Celanese plant,
which manufactures the material from which cigarette filters are made.
Employment at that location has remained steady or declined slightly in the past
three years. Several other small manufacturing concerns are located in
Montgomery and Giles Counties. These concerns manufacture diverse products and
are not dependent upon one sector of the economy.      
    
     Since 1988, Montgomery County has developed into a regional retail center,
with the construction of two large shopping areas. Two area hospitals, both of
which are affiliated with different large health care systems, have in the past
several years constructed additional facilities and attracted additional health
care providers to Montgomery      

                                       56
<PAGE>
 
    
County, making it a center for basic health care services. VPI & SU's Corporate
Research Center has brought several small high tech companies to Blacksburg, and
further expansion is planned.     
    
     Montgomery County has experienced good growth, with the total fair market
value of real estate, measured in constant dollars, increasing 49% in the years
between 1980 and 1992. Growth is predicted to continue through the year 2000;
however, the rate may be somewhat slower, as the predicted rate of population
growth in Montgomery County is expected to moderate. Neighboring Giles County is
more rural and had only 22% of Montgomery County's total population in 1990.
Giles County has experienced a slight decline in population since the 1990
census. Total fair market value of real estate, measured in real dollars,
increased in Giles County by 54% between 1980 and 1992, but declined by 9% over
that twelve-year period, as measured in constant dollars. The continued slow
decline of Giles County's population is predicted to continue through the year
2000. However, since the total population of the County reported in the 1990
census was only 16,366, and the population projected by the Virginia Employment
Commission for Giles in the year 2000 is 16,121, the predicted decline of 245
individuals is not expected to materially impact NBI's business in Giles County.
     
    
     NBI's primary service area offers the advantages of a good quality of life,
scenic beauty, moderate climate and the cultural attractions of two major
universities. The region has marketed itself as a retirement destination, and it
has had some recent success attracting retirees, particularly from the Northeast
and urban Northern Virginia. These marketing efforts are expected to continue. 
         
Competition      

     The commercial banking industry is extremely competitive. Many other
commercial banks are headquartered or have offices in NBB's service area, some
of which do business at several locations. Regional financial institutions
headquartered elsewhere compete in NBB's service area and have substantially
greater resources than NBB. Although NBB's main competition is from other
commercial banks, there is also competition from credit unions, savings banks,
savings and loan institutions, consumer finance companies and commercial finance
and leasing companies doing business in the service area.

     The principal methods of competition in the banking industry are rates
offered on loans and deposits and service and convenience of location. NBB is
generally competitive with other financial institutions in its service area with
respect to interest rates paid on time and savings deposits, service charges on
deposit accounts and interest rates charged on loans. Management believes that
NBB is able to compete successfully in this environment because of its service-
based business philosophy, well trained and customer oriented staff, and the
convenience of its office locations.

     The business of NBB and its competition with other banks and other types of
financial institutions will continue to be affected by legislative and
regulatory developments. Virginia's "opt in" to the Interstate Act (as defined
below) will allow financial institutions with much greater resources than those
in NBB's service area to establish business operations that will compete
directly with NBB. See "CERTAIN REGULATORY CONSIDERATIONS."
    
     On December 31, 1995, NBB employed a total of 96 full-time and four 
part-time employees in its main office and branch locations, and NBI had five
officer-employees. Employees are not represented by any union, and management
believes that employee relations are satisfactory.     

     NBI's principal offices are located at 100 Main Street, Blacksburg,
Virginia 24060.

Principal Holders of NBI Common Stock
    
     As of December 31, 1995, NBI had 1,714,152 shares of common stock ($2.50
par value) issued and outstanding. The following table sets forth, as of
September 30, 1995, the shares of common stock beneficially

             NBI MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
                      CONDITION AND RESULTS OF OPERATIONS
    
     The following discussion is an analysis of the financial condition and
results of operations of NBI for the years ended 1994, 1993 and 1992 and the
three months and nine months ended September 30, 1995 and 1994. The discussion
should be read in conjunction with the consolidated financial statements and
related notes included elsewhere in this Prospectus/Proxy Statement. See
"FINANCIAL STATEMENTS" and "RECENT DEVELOPMENTS."      

Years Ended December 31, 1994, 1993 and 1992

     Performance Summary.  NBI's net income increased $244,000, or 9.1%, in
1994, as compared to an increase of $344,000, or 14.8%, in 1993. Net interest
income after provision for loan losses increased $692,000 in 1994 and $736,000
in 1993. Noninterest income increased $66,000 between 1993 and 1994 and $254,000
between 1992 and 1993. Noninterest expense increased $303,000 in 1994 and
$455,000 in 1993.
    
     Net Interest Income.  Net interest income is the main component of NBI's
earnings and reflects net profits realized from loan, investment and deposit
activities. For 1994, net interest income totaled $8,907,000, compared to
$8,605,000 earned in 1993 and $7,999,000 in 1992. Interest expense on deposits
declined $182,000 in 1994, compared to a decline of $2,220,000 in 1993. At 
year-end 1994, market indicators such as high employment rates and high levels
of utilization of manufacturing capacities suggested the prospect of rising
interest rates in 1995. This was of particular concern to NBB as NBB is
liability sensitive for a period extending beyond one year. This would     

                                       60
<PAGE>
 
    
result in interest-sensitive liabilities repricing at a more rapid rate than
interest-sensitive assets. Provided that no other factors acted to mitigate this
process, NBB management believed that a compression of the interest margin was
possible and that earnings could be affected negatively. To maximize income
potential, minimize interest rate risk during periods of rate fluctuations and
insure adequate liquidity, NBI employs a formal asset/liability management
strategy.      
    
     The acquisition of deposits totaling $14,514,000 from First Union Bank of
Virginia significantly impacted NBI's net interest income for 1994. NBI is
generally liability sensitive in the one-year time frame. The influx of deposits
from the deposit acquisition produced a positive volume related change in
interest-earning assets; however, it created a negative rate change as these
assets were invested in lower yielding investments as insufficient loan demand
existed to absorb the funds. Asset yields produced by these events were lower in
comparison to asset yields in the prior year, 8.28% in 1994 compared to 8.83% in
1993. Loan yields declined from 9.65% in 1993 to 9.22% in 1994. The increasing
prime rate caused a substantial decline in commercial loan volume. The decrease
in commercial loan volume was offset in part by an increase in consumer loans at
lower rates. The build up of consumer loans primarily took place at the Pembroke
office (formerly a First Union Bank branch). In order to obtain this business,
NBI offered very aggressive loan pricing which caused a decline in yields.
Securities yields declined from 7.72% in 1994 to 6.99% in 1993. The federal
funds rate was up slightly in 1994 as it reacted to market changes more quickly.
Average loans, net totaled $111,708,000 in 1994 compared to $107,583,000 in 1993
and average securities totaled $69,260,000 in 1994 compared to $59,719,000 in
1993. Average interest-earning assets totaled $184,796,000 in 1994 compared to
$171,150,000 in 1993.     
    
     Interest expense was higher in 1994 due to the volume increase that
resulted from the acquisition of the First Union deposits. However, these
deposits were generally lower rate deposits than NBI's which lessened the impact
on interest expense. Average rates paid on deposits was 3.61% in 1994 compared
to 3.95% in 1993. With the additional liquidity, NBI was positioned to take a
less aggressive position in obtaining external funds which offset to some extent
the impact of the rising rate environment. Average interest-bearing liabilities
except for time deposits were comparable with the prior year. Average time
deposits increased $9,423,000 from $62,463,000 in 1993 to $71,886,000 in 1994,
and rates decreased from 5.25% to 4.62%. Average interest-bearing liabilities
totaled $156,620,000 in 1994 compared to $147,507,000 in 1993. The growth in
interest-earning assets and in deposits was due principally to the acquisition
of deposits from First Union Bank.     
    
     The year 1993, when contrasted with 1992, was a period of historically low
deposit rates. The cost of interest-bearing liabilities declined by 126 basis
points. At the same time the yield on interest-earning assets declined by only
77 basis points producing a net increase in the net interest rate spread of 49
basis points. This is further demonstrated by rate and volume change data.
Income on interest-earning assets declined by $1,632,000 on a tax equivalent
basis of which $1,416,000 was attributable to rate while the cost of interest-
bearing liabilities decreased by $2,225,000, of which $1,575,000 was due to
rate. Individual interest-earning asset categories as well as the various
deposit types generally reflect the same trend with rate being the principal
cause of the change. Average loans, net totaled $107,583,000 in 1993 compared to
$109,780,000 in 1992 and yields declined from 10.44% to 9.65%. Average
securities totaled $59,719,000 in 1993 compared to $59,942,000 in 1992 and
yields declined from 8.54% to 7.72%. Average interest-earning assets totaled
$171,150,000 in 1993 compared to $174,395,000 in 1992. Average interest-bearing
demand deposits and savings deposits increased $11,070,000, from $73,837,000 in
1992 to $84,907,000 in 1993, and rates declined from an average of 4.07% to
3.00%. Average time deposits decreased $18,018,000, from $80,584,000 in 1992 to
$62,566,000 in 1993, and rates declined from 6.25% to 5.24%. Average interest-
bearing liabilities totaled $147,507,000 in 1993 compared to $154,536,000 in
1992. The rate environment caused a shift in the mix of deposits from time
deposits to the more liquid interest-bearing demand and savings deposits and a
reduction in time deposits.

     Provision and Allowance for Loan Losses. The level of allowance for loan
losses is based on management's judgment and analysis of current and historical
loss experience, risk characteristics of the portfolio, concentration risks and
asset quality considerations, as well as other internal and external factors,
such as general economic conditions. During 1994, management took a prudent
approach to reserving for losses by allocating $540,000 as a provision for loan
losses, compared to $930,000 and $1,060,000 in 1993 and 1992, respectively. Net
charge-offs for 1994 decreased $102,000, following a decrease of $269,000
between 1992 and 1993. The decrease in net-charge offs in 1994 was the result of
improvement in the loan portfolio attributable largely to improvement in the
local economy. The decrease in net charge-offs allowed management to lower the
provision while still maintaining a ratio of the allowance for loan losses to
loans, net of unearned income, of 1.73% at December 31, 1994. NBB's credit
review department performs pre-credit reviews of large credits and, on an
ongoing basis,      

                                       61
<PAGE>
 
conducts analyses to systematically evaluate loan quality, detect problems and
provide early warning of asset deterioration.
    
     Nonperforming loans (consisting of nonaccrual and restructured loans)
totaled $649,000, $2,462,000 and $1,390,000 at December 31, 1994, 1993 and 1992,
respectively. The ratio of the allowance for loan losses to nonperforming loans
at those dates was 309%, 83% and 128%, respectively. The allowance for loan
losses at December 31, 1993 was 83% of nonperforming loans; however, the
nonperforming loans were largely collateralized by real estate, which reduced
NBI's exposure. In management's judgment, the allowance was sufficient to cover
the uncollateralized portion.      
    
     Nonaccrual loans declined substantially in 1994 as foreclosures occurred.
Upon foreclosure, those portions of the loan not covered by collateral are
charged to the allowance for loan losses. Once transferred to other real estate
any subsequent deterioration of collateral that causes a decline in fair market
value is charged to income by adjusting the valuation allowance for other real
estate owned. Management believes nonaccrual loans have stabilized as the local
economy has improved. NBB also has an active program to convert nonperforming
loans to performing assets. Nonperforming assets (consisting of nonperforming
loans and other real estate owned) totaled $1,732,000, $2,687,000 and $2,227,000
at December 31, 1994, 1993 and 1992, respectively. The ratio of the allowance
for loan losses to nonperforming assets at those dates was 116%, 76% and 80%,
respectively.     
    
     Nonperforming loans and nonperforming assets do not include accruing
loans past due 90 days or more. Accruing loans past due 90 days or more totaled
$219,000, $326,000 and $756,000 at December 31, 1994, 1993 and 1992,
respectively.      
    
     Management has evaluated the various risk factors related to consumer
lending and as a result concluded that an increase in consumer lending could
result in an increased level of losses. Risk factors considered were the
unsecured nature of some of the loans, loans collateralized by vehicles, mobile
homes and real estate are subject to deteriorating collateral values, and
borrowers that are generally not of substantial financial stability such that
illness or loss of employment can place the repayment of the loan at risk. NBI
has not experienced a substantial level of charge-offs in consumer loans.
Management will continue to monitor consumer loan charge-offs and increase the
allowance if required. Accordingly, management reevaluated the allowance for
loan losses considering the relevant factors and concluded the allowance is
sufficient to absorb consumer loan losses.     
    
       Noninterest Income.  Noninterest income for 1994 and 1993 was $1,607,000
and $1,541,000, respectively, which represents an increase of $66,000 or 4.3%.
Service charges on deposits for 1994 were $667,000 and $594,000 in 1993, an
increase of $73,000 or 12.3%. This increase was due in part to the revision of
fee schedules in mid-1993 which were in effect for all of 1994 and a general
increase in business levels. Trust income was $417,000 for 1994 and $373,000 for
1993, an increase of $44,000 or 11.8% caused by the growth of trust assets which
increased $7,049,000 or 14.5% from 1993 to 1994. Credit card fees showed a
continuing trend of improvement, increasing $38,000 or 12.0% in 1994.      
    
       All categories of noninterest income experienced growth in 1993, with an
overall increase of $254,000 or 19.7% over 1992 noninterest income of
$1,287,000. Service charges on deposit accounts contributed significantly with
an increase of $72,000 in 1993. This is largely attributable to the increase in
scheduled fees implemented in June, 1993. Trust income continued to positively
impact noninterest income with a $76,000 increase in 1993 primarily due to
growth in trust assets.      
    
       The remainder of the categories fluctuated due to general business
conditions, with the exception of securities gains and losses, which show
nominal amounts in both years.      
    
       Noninterest Expense.  Noninterest expense was $6,158,000 in 1994
compared to $5,855,000 in 1993, and $5,400,000 in 1992, resulting in increases
of 5.2% in 1994 and 8.4% in 1993. In late 1993, the acquisition of NBB's credit
card processor, Atlantic States Bankcard Association, by First Data Resources
("FDR"), necessitated a conversion to FDR's computer system. An increase in
credit card expense of $69,000 in 1994 reflected FDR's       

                                       62
<PAGE>
 
    
higher fee structure. The 1994 noninterest expense figure also includes certain
costs associated with NBB's purchase in April, 1994 of the Pembroke, Virginia
office of First Union National Bank of Virginia. Deposit intangibles of $908,000
are being amortized over a ten-year period and goodwill of $447,000 is being
amortized on a straight-line basis over a fifteen-year period. Net costs of
other real estate owned were $37,000 in 1994, compared to $287,000 in 1993, due
to decreased losses and write-downs and lower maintenance and administrative
carrying expenses on the properties. The timing of acquisition and liquidation
of foreclosed assets, as well as the nature of the properties, affect the
expenses incurred. In 1993, salaries and employee benefits increased by $250,000
because of new hires, normal salary increases and expenses necessary to fund a
commitment to an employee performance incentive plan. Occupancy expense rose
$62,000 in 1993 due to extensive renovations at the Main Office location.      

     Income Taxes.  Higher taxable earnings in 1994 resulted in a $183,000
increase in federal income tax expense in 1994, as compared to $219,000 in 1993.
NBI's effective tax rate was 23.6% in 1994, 21.3% in 1993, and 17.6% in 1992.

     NBI has determined that a valuation allowance for the gross deferred tax
assets is not necessary due to the fact that the realization of the entire gross
deferred tax assets can be supported by the amount of taxes paid during the
carryback period available under current tax laws.

     Effects of Inflation.  NBI's consolidated income statements generally
reflect the effects of inflation. Since interest rates, loan demand and deposit
levels are related to inflation, the resulting changes are included in net
interest income. The most significant item which does not reflect the effects of
inflation is depreciation expense, because historical dollar values used to
determine this expense do not reflect the effect of inflation on the market
value of depreciable assets after their acquisition.

     Balance Sheet.  In 1994, total assets increased $13,033,000, after an
increase of $4,099,000 in 1993. Total loans increased $4,059,000 in 1994,
compared to a $5,141,000 increase in 1993, and total deposits increased
$10,934,000 in 1994, compared to a $2,069,000 increase in 1993. Management
currently expects future improvement in the local economy, which should continue
to positively impact asset growth.

     Loans. Total loans increased 3.6%, following an increase of 4.7% between
1992 and 1993. Management continued to emphasize expansion of the consumer loan
portfolio, succeeding in this effort with an $8,522,000 increase in loans to
individuals in 1994, compared to a $6,036,000 increase in 1993. This emphasis on
consumer loans and the resulting growth in that category of loans was a major
factor leading to the increase in total loans. At year-end 1994, management
expected loan volume to remain steady due to uncertainty in the interest rate
environment.
    
     Securities.  As a result of the investment of funds acquired in a
purchase of deposits, securities held to maturity and available for sale at
December 31, 1994 increased $6,985,000 over 1993. Effective January 1, 1994, NBI
adopted the provisions of Statement of Financial Accounting Standards ("SFAS")
No. 115, "Accounting for Certain Investments in Debt and Equity Securities."
Upon adoption of SFAS No. 115, certain investment securities totaling
$17,451,000 were reclassified from securities held to maturity to securities
available for sale. NBI has classified all of its investment securities as
either held to maturity or available for sale because NBI does not maintain a
securities trading account.      

     NBB's investment policy stresses safety with a program of purchasing high
quality securities such as U.S. Treasury and U.S. Government Agency issues,
state, county and municipal bonds, corporate bonds, and other bank qualified
investments. Management adjusts its investment strategy in response to market
conditions and available investment vehicles.

     Deposits. On April 16, 1994, NBB purchased the deposits of the Pembroke
Office of First Union National Bank of Virginia. As a result, NBB assumed
$14,514,000 in total deposits and $33,000 in accrued interest payable. By 
year-end 1994, NBI's total deposits had increased $10,934,000 over 1993.

                                       63

     Average deposits at December 31, 1994 totaled $176,413,000 compared to
$164,402,000 at December 31, 1993, an increase of $12,011,000. Average
noninterest-bearing demand deposits increased $3,238,000 and average time
deposits increased $9,423,000, with average interest-bearing demand deposits and
average savings deposits showing insignificant changes from the prior year. The
growth in deposits was funded principally by the purchase of deposits from First
Union National Bank of Virginia. Without the purchase of these deposits, deposit
growth would have slightly declined. Average interest rates on interest-bearing
deposits declined in 1994 compared to 1993 by 34 basis points as management
offered rates to prevent deposit runoff, but not at a more aggressive level that
would be required to encourage growth. This trend is expected to continue as the
Merger of NBI and BTC will create additional liquidity for the consolidated
company. Please refer to "NBI STATISTICAL DATA--Analysis of Net Interest
Earnings and Deposits" for additional information.      

     Capital Resources.  Total stockholders' equity increased $1,883,000 from
1993 to 1994. Net income, less cash dividends on common stock of $993,000, and
the issuance of NBI common stock to NBI's Employee Stock Ownership Plan for
$86,000 account for this increase. The $126,000 decrease in stockholders' equity
at December 31, 1994 represents the excess of amortized costs over the fair
values of securities available for sale, net of income taxes, at year-end as
prescribed by SFAS No. 115. Net unrealized gains or losses on securities
available for sale, net of income taxes, which is recorded as a separate
component of stockholders' equity, will continue to be subject to change in
future years due to fluctuations in fair values, sales, purchases, maturities
and calls of securities classified as available for sale. There are no expected
material changes in the mix or relative cost of capital resources.

     NBI has operated from a consistently strong capital position.  The ratio
of total stockholders' equity to total assets was 10.08% at year-end 1994
compared to 9.78% at year-end 1993. Banks are required to apply percentages to
various assets, including off-balance sheet assets, to reflect their perceived
risk. Regulatory defined capital is divided by risk-weighted assets in
determining a bank's risk-based capital ratio. No regulatory authorities have
advised NBI or NBB of any specific leverage ratios applicable to them. Both
NBI's and NBB's capital adequacy ratios exceed regulatory requirements, and they
provide added flexibility to take advantage of business opportunities as they
arise.

     Liquidity. Liquidity is the ability to provide sufficient cash flow to meet
financial commitments and to fund additional loan demand or withdrawal of
existing deposits. Sources of liquidity include deposits, loan principal and
interest repayments, securities sales, calls and maturities and short-term
borrowings. NBB maintained an adequate liquidity level during 1994 and 1993.
Management is not aware of any future capital expenditures or other significant
demands or commitments which would result in material increases or decreases in
liquidity.      
    
     Net cash provided from operations which consisted principally of net income
amounted to $5,297,000, $4,078,000 and $3,342,000 in 1994, 1993 and 1992,
respectively. Cash flows from financing activities which consists principally of
increases in deposits amounted to $8,672,000 in 1994 and $1,215,000 in 1993.
Cash flows from operations and financing activities were invested in loans and
securities in 1994 and 1993. In 1992 due to a reduction in interest rates for
large certificates of deposit, net deposits decreased by $4,721,000 which was
funded by cash from operations and a reduction in the loan portfolio. Please
refer to "NBI'S Consolidated Statements of Cash Flows for the Years Ended
December 31, 1994, 1993 and 1992" for additional information.      

     Future Accounting Considerations. The Financial Accounting Standards Board
("FASB") has issued SFAS No. 114, "Accounting by Creditors for Impairment of a
Loan." SFAS No. 114 requires that certain loans which have been determined to be
impaired be measured based on the present value of expected future cash flows
discounted at the loan's effective interest rate or, as a practical expedient,
at the loan's observable market price or the fair value of the collateral if the
loan is collateral dependent. SFAS No. 114 also requires creditors to evaluate
the collectibility of both contractual interest and contractual principal of all
receivables when assessing the need for a loss accrual.

     In October 1994, the FASB issued SFAS No. 118, "Accounting by Creditors for
Impairment of a Loan - Income Recognition and Disclosures." SFAS No. 118 amends
SFAS No. 114 to allow a creditor to use existing methods for recognizing
interest income on an impaired loan. To accomplish that, SFAS No. 118 eliminates
the provisions in SFAS No. 114 that described how a creditor should report
income on an impaired loan. SFAS No. 118 does not change the provisions in SFAS
No. 114 that required a creditor to measure impairment based on the present
value of expected future cash flows discounted at the loan's effective interest
rate, or as a practical expedient, at the observable market price of the loan or
the fair value of the collateral if the loan is collateral dependent. SFAS No.
118 amends the disclosure requirements in SFAS No. 114 to require information
about the recorded investment in certain impaired loans and about how a creditor
recognizes interest income related to those impaired loans.

     SFAS No. 118 is effective concurrent with the effective date of SFAS No.
114. The mandatory adoption date of SFAS No. 114 and SFAS No. 118 by NBI was
January 1, 1995 and, consistent with the requirements of SFAS No. 114, they were
adopted by NBI on a prospective basis. NBI did not elect early adoption of SFAS
No. 114 and SFAS No. 118 and anticipates that the effects of adoption will not
materially impact its consolidated financial statements.

Three Months Ended September 30, 1995 and September 30, 1994

     Performance Summary. Net income for the current quarter amounted to
$827,000, an increase of $24,000 or 3.0% over the corresponding quarter in 1994.
This increase resulted from a decrease in the provision for loan losses, an
increase in noninterest income and an increase in noninterest expense.

     Net Interest Income. Net interest income increased $18,000 or 7.6% in the
current quarter over the corresponding quarter in 1994. Interest income
increased $347,000 or 9.2% due to an increase in loans. Interest expense
increased $329,000 or 23.1% due to an increase in deposits.

     Provision and Allowance for Loan Losses. The provision for loan losses
decreased $65,000 or 43.3% in the current quarter over the corresponding quarter
in 1994 due to a decline in net charge offs and a stabilization of past due and
nonaccrual loans. Management considers the provision adequate.

                                       65
<PAGE>
 
     Noninterest Income. Noninterest income increased $55,000 or 14.2% in the
current quarter over the corresponding quarter in 1994 due to an increase in
service charges on deposit accounts, credit card fees, and trust income.

     Noninterest Expense. Noninterest expense increased $74,000 or 4.7% in the
current quarter over the corresponding quarter in 1994 due principally to
increases in salaries and employee benefits, credit card processing and net
costs of other real estate owned.

     Income Taxes. NBI's effective tax rate for the current quarter of 25.0% is
comparable to the 22.7% effective rate in the corresponding quarter of 1994.

Nine Months Ended September 30, 1995 and September 30, 1994

     Performance Summary.  Net income for the nine months ended September 30,
1995 increased $176,000 or 7.8% compared to the corresponding period of the
previous year. This compared to a $321,000 or 16.5% increase for the September
30, 1994 period compared to September 30, 1993. The increase in net income for
the nine months ended September 30, 1995 was attributable principally to an
increase in net interest income, a decrease in the provision for loan losses and
an increase in noninterest expense.
    
     Net Interest Income. Net interest income increased $369,000 or 5.6% from
1994 to 1995 compared to an increase of $211,000 or 3.3% from 1993 to 1994.
Interest income increased $1,153,000 over 1994 due to increases in loan volume
and rates, shift of funds from investments to loans, and changes in the yields
on other earning assets. Interest expense increased $784,000 from 1994 to 1995
due to changes in the mix of deposit liabilities to time deposits.      
    
     The yield on interest-earning assets was 8.90% for the nine months ended
September 30, 1995 increasing from 8.28% in 1994, an increase of 84 basis
points. The cost of interest-bearing liabilities increased from 3.56% to 4.21%
during the same time period, an increase of 65 basis points, which resulted in a
nominal increase in the interest rate spread in 1995. The net yield on average
interest-earning assets, which factors in both capital and demand deposits,
increased to 5.38% in 1995 up from 5.10% in 1994, a 28 basis point increase. The
increased yield on interest-earning assets was the result of the shifting of
investments to the higher yielding loan portfolio. Deposit growth was nominal as
the need for external funds was not necessary due to excess internal liquidity.
This allowed NBB to take a less aggressive stance on obtaining external funds
and avoid the inherent cost of funds in a highly competitive market. Average
loans, net totaled $117,847,000 for the nine months ended September 30, 1995
compared to $110,942,000 for the nine months ended September 30, 1994 and yields
increased from 9.18% to 10.01%. Average securities totaled $66,195,000 for the
nine months ended September 30,1995 compared to $72,574,000 for the nine months
ended September 30, 1994 and yields increased from 6.56% to 7.07%. Average
interest-earning assets totaled $187,531,000 for the nine months ended September
30, 1995 compared to $187,092,000 for the nine months ended September 30, 1994.
Average interest-bearing demand deposits and savings deposits decreased
$9,702,000, from $84,794,000 for the nine months ended September 30, 1994 to
$75,092,000 for the nine months ended September 30, 1995, and rates increased
from 2.70% to 3.01%. Average time deposits increased $10,297,000, from
$70,504,000 for the nine months ended September 30, 1994 to $81,431,000 for the
nine months ended September 30, 1995, and rates increased from 4.62% to 5.31%.
Average interest-bearing liabilities totaled $156,585,000 for the nine months
ended September 30, 1995 compared to $155,298,000 for the nine months ended
September 30, 1994. Please refer to "NBI STATISTICAL DATA--Analysis of Net
Interest Earnings and Analysis of Changes in Interest Income and Interest
Expense" for additional information.     

     Provision and Allowance for Loan Losses. The provision for loan losses
decreased $155,000 or 40.8% in 1995 compared to 1994 because past due and
nonaccrual loans have stabilized. The allowance for loan losses to period-end
loans, net of unearned income, approximated 1.70% at September 30, 1995,
compared to 1.73% at December 31, 1994. Management considers the provision
adequate.
    
     Nonperforming loans (consisting of nonaccrual and restructured loans)
totaled $420,000 at September 30, 1995 compared to $649,000 at December 31,
1994. The ratio of the allowance for loan losses to nonperforming loans at those
dates was 501% and 309%, respectively. Nonperforming assets (consisting of
nonperforming loans and other real estate owned) totaled $1,366,000 at September
30, 1995 compared to $1,732,000 at December 31, 1994. The ratio of the allowance
for loan losses to nonperforming assets at those dates was 154% and 116%,
respectively. Nonperforming loans and nonperforming assets do not include
accruing loans past due 90 days or more. Accruing loans past due 90 days or more
totaled $191,000 at September 30, 1995 and $219,000 at December 31, 1994. Please
refer to "NBI STATISTICAL DATA--Risk Elements and Summary of Loan Loss
Experience" for additional information.      

                                       66
<PAGE>
 
     Noninterest Income.  During the first nine months of 1995, total
noninterest income rose $35,000 or 2.8% over the same period last year. This
increase was due primarily to increases in service charges on deposit accounts,
credit card fees and other income.

     Noninterest Expense.  Noninterest expense increased $302,000 or 6.7% for
the nine months ended September 30, 1995, compared to a $206,000 or 4.8%
increase for the 1993 to 1994 period. The largest component of the increase was
due to the increased cost of salaries and employee benefits. Fringe benefit
costs for pension, medical and dental coverage have increased in the past year.
Other operating expense increases were in the areas of data processing, credit
card processing and net costs of other real estate owned. Net costs of other
real estate owned increased $56,000 due mainly to write-downs of OREO property.
The FDIC assessment decreased by $19,000 reflecting a decrease in the FDIC rate
charged for deposits.

     Income Taxes. NBI's effective tax rate of 23.5% for the nine months ended
September 30, 1995 is comparable to 22.8% for the nine months ended September
30, 1994.

     Balance Sheet. Total assets have risen $6,953,000 since year-end 1994. This
increase is the result of stronger loan demand for all categories of loans.
Total deposits increased $4,516,000 since year-end 1994 with time deposits
increasing $9,392,000. This increase was a result of higher rates paid on time
deposits compared to rates paid on interest-bearing and savings deposits. NBI's
stockholders' equity was $22,257,000 at September 30, 1995, compared to
$20,137,000 at year-end 1994. The increase of $2,120,000 resulted from earnings
retention and a turnaround in net unrealized gains on securities available for
sale.
    
     Deposits. Average deposits at September 30, 1995 totaled $178,344,000
compared to $176,413,000 at December 31, 1994, an insignificant change. There
was a change in mix, as average time deposits increased $9,545,000 while average
interest-bearing demand deposits and average savings deposits decreased
$5,465,000 and $3,803,000, respectively. This is attributed to the higher rates
paid on time deposits as average rates on time deposits increased to 5.31% in
1995 from 4.62% for the year ended December 31, 1994. Please refer to "NBI
STATISTICAL DATA--Analysis of Net Interest Earnings and Deposits" for additional
information.      

     Liquidity. NBI maintained an adequate level of liquidity during the first
nine months of 1995 and 1994. The liquidity ratio was 23.8% at September 30,
1995, and 27% at September 30, 1994. Certain assets are maintained on a short-
term basis to meet liquidity demands anticipated by management.
    
     The 1995 nine month cash flow data related to investing activities reflects
the previously noted shift from the investment categories to loans. Net cash
provided from operating activities totaled $2,319,000 and net deposits gathered
in financing activities increased approximately $4,516,000. Cash and due from
banks decreased approximately $1,267,000 from the beginning of 1995. The net
decrease in cash and due from banks plus the net cash from operations and
financing activities were invested primarily in loans. Please refer to "NBI'S
CONSOLIDATED STATEMENTS OF CASH FLOWS FOR THE NINE MONTHS ENDED SEPTEMBER 30,
1995" for additional information.      
    
     In the fourth quarter of 1995, NBI utilized a one-time opportunity and
transferred approximately $8,199,000 from the held to maturity securities
classification to the available for sale category which effectively converted
these assets to a current asset and in doing so enhanced liquidity. While
management continues its efforts to shift investments to the loan portfolio,
management foresees no events, including the shift of investments to loans, that
would severely impair liquidity.     

     Capital Resources. NBI continues to maintain a strong capital position with
the increase in total capital attributable to retained earnings and the adoption
of SFAS No. 115. Both NBI's and NBB's capital adequacy ratios exceed regulatory
requirements, and they provide added flexibility to take advantage of business
opportunities as they arise.

     Interest Rate Sensitivity Position. NBI's future earnings may be adversely
affected by a sharp upturn in interest rates, as NBI is liability sensitive for
a period extending beyond one year. In a falling rate environment, earnings
would benefit to some extent from this position, as assets at higher rate levels
would generally reprice downward at a slower rate than interest sensitive
liabilities.     
    
     At the one to five year period, NBI's cumulative interest-sensitivity
position reflects an asset sensitive position indicating that the benefit
derived from falling rates and the adverse effect of rising rates would
dissipate in the one to five year time period. This would be dependent, however,
on the length of time rates were rising and falling and the length of time rates
remained stable at the level ultimately reached. Management typically adjusts
its assets/liability strategies during times of rising and falling rates to
minimize or maximize the impact of changing rates. Please refer to "NBI

     Proposed Merger. The proposed Merger of NBI and BTC will have a combination
of positive and negative effects on NBI's financial position, results of
operations, liquidity and capital. While both entities have strong earnings,
NBI's return on assets and equity can be expected to decline due to the lower
ratios exhibited by BTC. BTC's lower ratios are due to its excess liquidity
which is presently invested in the securities portfolio due to the lack of loan
demand in BTC's trade area. It is expected that BTC's ratios could be enhanced
over time by purchasing loans from NBB, as NBB's trade area is more developed
and loan demand is higher. The shifting of investments to the loan portfolio
would create higher yields for BTC and should result in improved net interest
income. Also, with the excess liquidity of BTC and the potential loan generating
ability of NBB, the combined banks will be in a position to adopt a strategy
that allows them to take a less aggressive stand toward obtaining external funds
and thereby avoid to some extent higher funding costs. Loan demand in NBB's
trade area will ultimately be the determining factor in improved performance,
the demand being dependent on economic conditions which are subject to
fluctuations. Management views this process as an intermediate to longer term
goal. Both NBI and BTC have strong capital positions which have generally
trended upward, the result of earnings growth coupled with a generally moderate
dividend payout.     
    
     The overall impact of the Merger is expected to be positive with regard to
liquidity and capital; however, excess liquidity will have to be absorbed into
BTC's loan portfolio to increase net income. The minimal levels of noninterest
income at BTC also are viewed as a potential opportunity for increased income in
the future.

    equivalent basis using a Federal income tax rate of 34% in 1995, 1994 and
    1993.
(2) Loan fees of $156 in 1995, $193 in 1994 and $593 in 1993 are included in 
    total interest income.
(3) Nonaccrual loans are included in average balances for yield computations.
(4) Annualized.

     C.  ANALYSIS OF CHANGES IN INTEREST INCOME AND INTEREST EXPENSE

     NBI's primary source of revenue is net income, which is the difference
between the interest and fees earned on loans and investments and the interest
paid on deposits and other funds. NBI's net interest income is affected by
changes in the amount and mix of interest-earning assets and interest-bearing
liabilities and by changes in yields earned on interest-earning assets and rates
paid on interest-bearing liabilities. The tables below set forth, for the
periods indicated, a summary of the changes in interest income and interest
expense resulting from changes in average asset and liability balances (volume)
and changes in average interest rates (rate).

     INTEREST RATE SENSITIVITY

     The tables below set forth, as of the dates indicated, the distribution
of repricing opportunities of NBI's interest-earning assets and interest-bearing
liabilities, the interest rate sensitivity gap (i.e., interest rate sensitive
assets less interest rate sensitive liabilities), the cumulative interest rate
sensitivity gap ratio (i.e., interest rate sensitivity gap divided by total
interest-earning assets) and the cumulative interest rate sensitivity gap ratio.
The tables set forth the time periods during which interest-earning assets and
interest-bearing liabilities will mature or may reprice in accordance with their
contracted terms.

     Certain shortcomings are inherent in the method of analysis presented in
the following tables. For example, although certain assets and liabilities may
have similar maturities or periods of repricing, they may react in different
degrees and at different times to changes in market interest rates. Also, loan
prepayments and early withdrawals of certificates of deposit could cause the
interest sensitivities to vary from those which appear on the tables.

                                       71

     NBI has a formal asset/liability management program. The primary goal of
the program is to provide management with information related to the rate
sensitivity of certain assets and liabilities and the effect of changing rates
on profitability and capital accounts. While this planning process is designed
to protect NBB over the long-term, it does not provide near-term protection from
"interest rate shocks," as interest rate sensitive assets and liabilities do
not, by their nature, move up or down in tandem in response to changes in the
overall rate environment. Therefore, NBI's profitability in the near-term may
temporarily be affected, either positively by a falling interest rate scenario,
or negatively by a period of rising rates.     
    
     An interest rate sensitivity gap is considered positive when the amount of
interest rate sensitive assets exceeds the amount of interest rate sensitive
liabilities. A gap is considered negative when the amount of interest rate
sensitive liabilities exceeds the amount of interest rate sensitive assets.
During a period of rising interest rates, a negative gap would generally tend to
affect adversely net interest income while a positive gap would generally tend
to result in an increase in net interest income. During a period of declining
interest rates, a negative gap would generally tend to result in increased net
interest income, while a positive gap would generally tend to affect adversely
net interest income. NBI's future earnings may be adversely affected by a sharp
upturn in interest rates as NBI is liability sensitive for a period extending
beyond one year. In a falling rate environment earnings would benefit to a
certain degree from this position, because assets at higher rate levels would
reprice downward at a slower rate than interest sensitive liabilities. Over the
one to five year period, NBI's cumulative interest-sensitivity position reflects
an asset sensitive position. This would mean NBI would benefit initially from
falling rates and the adverse effect of rising rates but would benefit in the
one to five year period from rising rates. This would depend, however, on the
length of time rates were rising and falling and the length of time rates
remained stable at the level ultimately reached.

     NBI is sensitive to interest rate changes, as liabilities generally reprice
or mature before interest-earning assets. The above gap table reflects NBI's
rate-sensitive position at September 30, 1995, and is not necessarily reflective
of its position throughout the year. The carrying amounts of interest-rate
sensitive assets and liabilities are presented in the periods in which they
reprice to market rates or mature and are summed to show the interest-rate
sensitivity gap.

     NBI is sensitive to interest rate changes, as liabilities generally reprice
or mature before interest-earning assets. The above gap table reflects NBI's
rate-sensitive position at December 31, 1994, and is not necessarily reflective
of its position throughout the year. The carrying amounts of interest-rate
sensitive assets and liabilities are presented in the periods in which they
reprice to market rates or mature and are summed to show the interest-rate
sensitivity gap.

     Factors influencing management's judgment in determining the amount of the
loan loss provision charged to operating expense include the quality of the loan
portfolio as determined by management, historical loan loss experience,
diversification as to type of loans in the portfolio, the amount of secured as
compared with unsecured loans and the value of underlying collateral, banking
industry standards and averages, and general economic conditions.

     B.  ALLOCATION OF THE ALLOWANCE FOR LOAN LOSSES
    
     The allowance for loan losses has been allocated according to the amount

                                BUSINESS OF BTC

History and Business

     The antecedents of BTC are in a charter issued on September 28, 1889 for
Clinch Valley Bank. On December 22, 1893, another charter was issued in
substantially the same form and to virtually the same organizers for a bank to
be called Bank of Clinch Valley. In 1929, Bank of Clinch Valley merged with
Farmers National Bank, under the charter of the former, and the name of the
resulting institution became "Farmers Bank of Clinch Valley." The name "Bank of
Tazewell County" resulted from the 1964 merger of Bank of Graham, Bluefield,
Virginia, with Farmers Bank of Clinch Valley.

     As a bank chartered under the laws of the Commonwealth of Virginia, BTC is
subject to primary supervision, examination and regulation by the BFI and is
subject to applicable provisions of Virginia law insofar as such provisions do
not conflict with or are not preempted by federal banking laws. BTC is also a
member of the Federal Reserve System and, therefore, under the supervision of
the Federal Reserve Board. As a member of the Federal Reserve System, it is
subject to a variety of federal banking laws and regulations. The deposits of
BTC are also insured under the Federal Deposit Insurance Act, up to the
applicable limits thereof. See "CERTAIN REGULATORY CONSIDERATIONS."

     BTC presently has no corporate parent, subsidiaries or other affiliates. At
September 30, 1995, BTC had approximately $177 million in assets, $41 million in
net loans, $150 million in deposits and $25 million in stockholders' equity.

Banking Services
    
     BTC is engaged in substantially all of the business operations customarily
conducted by independent commercial banks in Virginia. Most of BTC's business
originates from the communities of Tazewell and Bluefield and other communities
in Tazewell County, Virginia and in Mercer County, West Virginia. BTC's service
area has largely depended on the coal mining industry and farming for its
economic base. In recent years, coal companies have mechanized and have reduced
the number of persons engaged in the production of coal. There are still a
number of support industries for the coal mining business that continue to
provide employment in the area. Additionally, several new businesses have been
established in the area, and Bluefield, West Virginia has begun to       

                                       82
<PAGE>
 
    
emerge as a regional medical center. Unemployment has stabilized, and real
estate values also remain stable and comparable to other areas in southwest
Virginia.     

     BTC provides its banking services from seven offices located in Tazewell
and Bluefield. BTC's banking services include the acceptance of checking and
savings deposits, and the making of commercial, real estate, personal,
automobile and other installment loans. BTC also offers trust services,
traveler's checks, notary public and other customary bank services to its
customers. BTC does not issue credit cards.

     BTC's deposits are attracted primarily from individuals and small business-
related sources. BTC also attracts deposits from several local agencies. In
connection with municipal deposits, BTC is generally required to pledge
securities to secure such deposits, except for the first $100,000 of such
deposits, which are insured by the FDIC.

     As of September 30, 1995, BTC had approximately 16,450 deposit accounts,
representing approximately 6,150 noninterest-bearing (demand) accounts with
balances totaling approximately $16.6 million for an average balance per account
of approximately $2,700; 6,600 savings, interest-bearing demand and money market
accounts with balances totaling approximately $55.2 million for an average
balance per account of approximately $8,400 and 3,700 time certificate of
deposit accounts with balances totaling approximately $79 million for an average
balance per account of approximately $21,500.
    
     BTC's principal lending focus is on real estate loans in its service area
with a particular emphasis on adjustable rate residential or commercial mortgage
loans. Mortgage loans, including commercial mortgages, constituted approximately
66% of BTC's loan portfolio at September 30, 1995. Approximately 48% of the
mortgage loan portfolio is comprised of residential mortgages with the remainder
being comprised of commercial mortgage loans. Residential mortgage loans are
typically secured by single family residences, including mobile units, located
throughout BTC's service area. Commercial mortgage loans are typically secured
by small office buildings or multi-use commercial/industrial buildings.
Mortgage loans are generally made for terms of from one to ten years with
sixteen to twenty year amortizations and based on various adjustable rate
indexes depending on whether the mortgage loan is residential or commercial.
Mortgage loans are generally underwritten with loan-to-value ratios ranging from
approximately 75% to 80%.      
    
     BTC's commercial loans include loans made primarily to service, retail and
wholesale businesses for a variety of purposes, including revolving lines of
credit, working capital loans and equipment financing loans. Commercial loans
constituted approximately 16% of BTC's loan portfolio at September 30, 1995.
Although BTC typically looks to the borrower's cash flow as the principal source
of repayment of such loans, the large majority of the commercial loans are
secured by some form of collateral, including equipment, accounts receivables
and both commercial and residential real estate.      
    
     BTC's consumer loans represented 18% of the loan portfolio at September 30,
1995.  Consumer loans include automobile loans and other loans for personal
purposes.      
    
     A significant portion of BTC's loan portfolio is secured by real estate.
One of the principal risks inherent in lending secured by real estate is a
decline in the market value of the underlying real property collateral. The
general economy in BTC's service area is suffering from the effects of a decline
in the coal industry. This has generally resulted in a weak loan demand but real
estate values have remained stable and comparable to other areas in southwest
Virginia.      

     BTC has a loan-to-one borrower limit of approximately $3.8 million, with
BTC's largest loan being approximately $1.3 million. BTC originates and
processes most of its loans and holds these loans in its portfolio until
maturity or their earlier repayment. It frequently purchases loans or
participations in loans from other financial institutions which experience
stronger loan demand than does BTC. Approximately 20% of BTC loan portfolio is
comprised of loans or interests in loans that BTC has purchased. BTC seldom
sells loans to other financial institutions and does not sell loans in the
secondary market. BTC has adopted a Federal Mortgage Loan Policy      

                                       83

which generally complies with recommendations by the Federal Reserve Board. All
other loans are based on collateral, credit standards and net worth
considerations. BTC's Board of Directors will periodically adjust BTC's
underwriting criteria in response to economic conditions and business
opportunities.     

     The principal sources of BTC's revenues are (i) interest and fees on loans;
(ii) interest on investments; (iii) service charges on deposit accounts and
other charges and fees; (iv) income from fiduciary activities; and (v) interest
on federal funds sold (funds loaned on short-term basis to other banks). For the
year ended December 31, 1994, these sources comprised 32%, 61%, 2%, 1% and 4%,
respectively, of BTC's total operating income.

     BTC has not engaged in any material research activities relating to the
development of new services or the improvement of existing bank services since
1994, when ATMs were opened in the Cumberland Park and Westgate branch offices.

     There has been no significant change in the types of services offered by
BTC in the last ten years, except in connection with new types of accounts
allowed by statute or regulation in recent years and the introduction of ATMs at
two of its branch offices. BTC has no present plans regarding "a new line of
business" requiring the investment of a material amount of total assets.

     There is no emphasis on foreign sources and application of funds. BTC's
business, based upon historical performance, is not seasonal. BTC is not
dependent upon a single customer or group of related customers for a material
portion of its deposits, nor is a material portion of BTC's loans concentrated
within a single industry or group of related industries. Management of BTC is
unaware of any material effect upon BTC's capital expenditures, earnings or
competitive position as a result of federal, state or local environmental
regulation.

     BTC holds no patents, licenses (other than licenses obtained from bank
regulatory authorities), franchises or concessions.

Trust Department

     Through its trust department, BTC conducts a general trust business in its
service area, including personal and corporate trust services. Personal trust
services include the administration and settlement of decedents' estates,
administration of testamentary and inter vivos trusts, and agency or custodian
accounts. Corporate trust service include acting as administrator or trustee of
employee benefit plans, including BTC's Employees' Pension Plan. The trust
department has approximately 104 accounts with approximately $21 million in
assets under administration. Fiduciary assets under the administration of the
trust department are not included among the assets of BTC for purposes of its
financial statements or financial reporting.

Employees

     As of September 30, 1995, BTC had a total of 68 full-time employees and one
part-time employee. The management of BTC believes that its employee relations
are satisfactory.

Properties

     BTC currently owns the land and buildings of six of its seven offices.  BTC
leases the land and the building at which the Westgate branch office is located.
The lease provides for an annual rental of $13,000 and expires in September
2003. BTC believes that its existing facilities are adequate for its current
needs and any anticipated growth.

Legal Proceedings
    
     Due to the nature of its business, BTC is, from time to time, a party to
claims and legal proceedings arising in the ordinary course of business. BTC is
not currently a party to any such claim or proceeding.

     Competition

     The banking and financial services business in Virginia generally, and in
BTC's market areas specifically, is highly competitive. The increasingly
competitive environment is a result primarily of changes in regulation, changes
in technology and product delivery systems, and the accelerating pace of
consolidation among financial services providers. BTC competes for loans and
deposits and customers for financial services with other commercial banks,
savings and loan associations, securities and brokerage companies, mortgage
companies, insurance companies, finance companies, money market funds, credit
unions, and other nonbank financial service providers. Many of these competitors
are much larger in total assets and capitalization, have greater access to
capital markets and offer a broader array of financial services than BTC. In
order to compete with the other financial services providers, BTC principally
relies upon local promotional activities, personal relationships established by
officers, directors and employees with its customers, and specialized services
tailored to meet its customers' needs.

     Overview

     Net income was $1.8 million ($.95 per share) for the nine months ended
September 30, 1995 compared to net income of $2.0 million ($1.08 per share) for
the corresponding period in 1994. Net income for the three months ended
September 30, 1995 was $553,000 ($.29 per share) compared to $616,000 ($.33 per
share) for the corresponding period in 1994. The decline in net income for the
nine months ended September 30, 1995 as compared to the corresponding period in
1994 was due primarily to decreases in net interest income and noninterest
income.

     Net income was $2.4 million ($1.26 per share) for the year ended December
31, 1994 as compared to $3.0 million ($1.57 per share) and $2.4 million ($1.27
per share) for the years ended December 31, 1993 and 1992, respectively. The
decrease in net income in 1994 was due primarily to a decrease in noninterest
income and an increase in noninterest expense.

     Net Interest Income

     BTC's primary source of revenue is net interest income, which is the
difference between the interest and fees earned on loans and investments and the
interest paid on deposits and other funds. BTC's net interest income is affected
by changes in the amount and mix of interest-earning assets and interest-bearing
liabilities and changes in yields earned on interest-earning assets and rates
paid on interest-bearing liabilities.
    
     Net interest income declined $256,000 for the nine months ended September
30, 1995 compared to the corresponding period in 1994 because total interest
income grew at a slower rate than did total interest expense. This, in turn,
resulted from the average rates earned on interest-earning assets increasing at
a slower rate than did the average rates paid on interest-bearing liabilities.
The interest rate spread and the net yield on average interest earning assets
(both computed on a fully tax equivalent basis) declined 51 and 38 basis points,
respectively, at September 30, 1995 from their levels at December 31, 1994.
Interest margins continued to narrow during the fourth quarter of 1995.
Management of BTC believes that net interest income will improve in future
months, even in the face of projected declining interest rates, because it
expects to convert more of its investment securities into higher yielding loans
resulting from its affiliation with NBI.     

     Total interest income for the nine months ended September 30, 1995
increased by $437,000 from the comparable period in 1994. While an increase in
interest-earning assets contributed to such result, it was principally effected
by increased rates earned on such assets. Total interest expense for the nine
months ended September 30, 1995 increased by $693,000 from September 30, 1994.
Such increase was more greatly influenced by changes in the rates paid on
interest-bearing liabilities than in the increase in volume of these
liabilities.

     Net interest income increased $1,000 for the year ended December 31, 1994
as compared to the year-end results for 1993, as total interest income grew at
approximately the same rate as did total interest expense. The interest rate
spread on a fully tax equivalent basis increased one basis point from its level
at December 31, 1993. However, the yield on average interest-earnings assets on
a fully tax equivalent basis declined by five basis points from its level at
December 31, 1993. This decline reflects the general increase in market interest
rates and negative impact of interest rate floors on BTC's adjustable rate
loans. These interest rate floors adversely impacted net interest income in the
increasing interest rate environment because the actual rates on adjustable rate
loans did not increase initially and did not increase as rapidly as the increase
in the cost of interest-bearing liabilities.

     Total interest income for the year ended December 31, 1994 increased by
$100,000 from December 31, 1993. On a fully tax equivalent basis, an increase in
the volume of interest-earning assets was almost totally offset by a decrease in
the rates earned on such assets during the period. This decline in rates was the
result of loans repricing downward during the first and second quarters of 1994,
the impact of lowering the contractual interest rate floor on several loans to
their fully indexed rate. Total interest expense for the year ended December 31,
1994 increased by $100,000 from December 31, 1993. On a fully tax equivalent
basis, the decrease in rates paid on interest-bearing liabilities during the
period more than offset the increase resulting from volume. BTC changed its

                                       87
<PAGE>
 
deposit strategy in 1994 and began to focus on raising lower rate savings
deposits to facilitate the runoff of higher rate certificates of deposit. This
strategy was successful in reducing BTC's deposit costs during a rising interest
rate environment in the third and fourth quarters of 1994.

     For further information concerning net interest income, the rates earned
and paid on interest-earning assets and interest-bearing liabilities and the
effect of changes in rate and volume on these results, see "BTC STATISTICAL
DATA."

     Provision for Loan Losses

     BTC maintains an allowance for loan losses to cover the known and inherent
risk of loss associated with its loan portfolio. The provision for loan losses
is charged against income and is applied to the allowance for loan losses.

     The provision for loan losses declined $10,000 for the year ended December
31, 1994 compared to 1993, as management maintained the allowance for loan
losses at $545,000 even though period-end loans increased by $2.6 million. BTC
took no provision for loan losses during the nine months ended September 30,
1995, as recoveries on loans previously charged-off exceeded loans written-off
against the allowance for loan losses by $8,000. As a result of such recoveries,
the allowance for loan losses increased to $553,000 at September 30, 1995.
    
     Nonperforming loans increased from $-0- at December 31, 1994 to $299,000 at
September 30, 1995, and the related ratio of the allowance for loan losses was
185% at September 30, 1995. This increase can be attributed primarily to one
loan of $255,000. This loan, made originally to a husband and wife for farm
purposes, became nonperforming when the husband died and the wife subsequently
filed for bankruptcy under Chapter 12. The $255,000 amount is the court approved
planned amount of repayment. Management expects this nonperforming loan will be
settled in 1996, when the property will be sold. It believes that any resultant
loss from this particular loan or the other nonperforming loans would be
adequately covered by the existing unallocated allowance for loan losses.     

     Although BTC maintains its allowance for loan losses at a level which it
considers to be adequate to provide for potential losses, there can be no
assurance that such losses will not exceed the estimated amounts, thereby
adversely affecting the future results of operations. The calculation of the
adequacy of the allowance for loans losses is based on a variety of factors,
including underlying collateral values, delinquency trends and historical loan
loss experience.
 
     For further information concerning the allowance for loans losses and asset
quality, see "BTC STATISTICAL DATA."

     Noninterest Income

     Noninterest income for the nine months ended September 30, 1995 declined by
$92,000 as compared to September 30, 1994 principally as a result of a net
realized loss on securities of $85,000, as compared to a $4,000 gain for the
comparable period in 1994.

     Noninterest income for the year ended December 31, 1994 declined by
$418,000 as compared to year-end 1993 principally attributable to a $375,000
recovery in 1993 in connection with certain losses in the securities portfolio
which were recognized in prior years. For further discussion of the securities
portfolio, see "--Securities" below.

                                       88
<PAGE>
 
     Noninterest Expense

     Noninterest expense for the nine months ended September 30, 1995 increased
by $29,000 as compared to September 30, 1994, as salaries and employee benefits
increased by $12,000, occupancy and furniture and fixtures increased by $92,000
and other operating expenses declined by $75,000.

     Noninterest expense for the year ended December 31, 1994 increased by
$420,000 as compared to year-end 1993 principally resulting from an increase of
$69,000 in salaries and employee benefits, as well as a $331,000 increase in
other operating expense, principally attributable to $141,000 in additional
franchise taxes for 1992, 1993 and 1994 paid to the Commonwealth of Virginia as
a result of a deficiency in those years. The remaining $191,000 represented a
general increase in many of the other categories of other operating expenses,
including advertising, costs of examinations, insurance, supplies and the like.

     Income Taxes

     Lower taxable earnings during the first nine months of 1995 resulted in a
$122,000 decrease in federal income tax expense from the comparable period in
1994. Likewise, federal income tax expense declined $242,000 between December
31, 1994 and 1993 as a result of lower taxable earnings. BTC's effective tax
rate was 29.0% at September 30, 1995 as compared to 29.5% at September 30, 1994
and 28.3% at December 31, 1994, as compared to 28.5% at December 31, 1993.
 
     Balance Sheet

     Average total assets increased $3.3 million between December 31, 1994 and
September 30, 1995, while average total assets increased $5.5 million between
December 31, 1993 and 1994. This asset growth was reflected in BTC's investment
portfolio, with the average amount of securities held in all categories
increasing from $109.5 million at December 31, 1993 to $118.1 million at
September 30, 1995. Average net loans between December 31, 1993 and September
30, 1995 remained virtually identical in amount reflecting the continued lack of
significant loan demand in BTC's markets.

     Average total deposits increased $2.3 million between December 31, 1994 and
September 30, 1995, while average total deposits increased $5.5 million between
December 31, 1993 and 1994. Average demand deposits and average interest bearing
demand deposits remained stable between December 31, 1993 and September 30,
1995, increasing only approximately $837,000 in the aggregate. The mix of
savings and time deposits did change during this period as average savings
deposits decreased $6.1 million from December 31, 1993 to September 30, 1995,
while average time deposits increased $13.1 million during the same period. The
change in the mix of savings and time deposits and the overall increase in time
deposits reflects the increasing interest rates paid during the period as the
average rate on time deposits increased from 4.15% at December 31, 1993 to 5.04%
at September 30, 1995.

     Average stockholders' equity increased $974,000 between December 31, 1994
and September 30, 1995, while average stockholders' equity increased $835,000
between December 31, 1993 and 1994. These increases reflects earnings retention
and, in the case of the September 30, 1995 average amounts, the improvement in
net unrealized gains on securities available for sale resulting from the
application of SFAS 115.

     For additional information concerning average balance sheet amounts, see
"BTC STATISTICAL DATA."

     Securities

     Effective January 1, 1994, BTC adopted the provisions of SFAS No. 115,
"Accounting for Certain Investments in Debt and Equity Securities" promulgated
by the FASB. Upon adoption of SFAS No. 115, certain investment securities
totaling $25.0 million were reclassified from securities held to maturity to
securities available for sale. BTC has reclassified all of its investment
securities into these two categories because BTC does not maintain trading
securities.

     BTC investment policy stresses safety with a program of purchasing high
quality securities such as U.S. Treasury and U.S. government sponsored agency
issues, state, county and municipal bonds, corporate bonds and other bank
qualified investments. Management adjusts its investment strategy in response to
market conditions and available investment vehicles. At September 30, 1995, BTC
held approximately $119 million in investment securities, of which approximately
$107 million were issued by the U.S. Government or its agencies and
approximately $10 million by state and municipal issuers.     
    
     BTC purchased taxable housing bonds, known as Guaranteed Investment
Contracts, in 1986 which were guaranteed by Executive Life Insurance Company
("ELIC"). These bonds had a par value of $1,500,000 and had an initial value of
$1,470,842 on the books of BTC. At the time of purchase, the bonds were
considered a prudent investment and were rated as AAA by Standard & Poor's. No
housing was ever built with the proceeds of the bonds and, in 1991, ELIC
defaulted on the guaranty and was seized by the California Department of
Insurance. The following table sets forth certain information concerning these
bonds and BTC's actions in respect thereto since 1991:

</TABLE>      
    
     The write-downs in 1991-92 resulted from the uncertainty relating to the
ELIC seizure and liquidation, as well as regulatory pressure to write off a
portion of the bonds. With improving economic conditions in 1993, the market
value of the bonds increased significantly and management of BTC booked a
$375,000 write-up believing that the write-offs in 1991-92 had been too large.
With the partial payments of principal in 1994, management believed that BTC
might receive total recovery of the remaining carrying value of the bonds and,
as a result, no additional write-offs or write-ups were made during the year.
During 1995, BTC received additional principal payments and at December 31,
1995, the estimated market value of the bonds exceeded their carrying value on
the books of BTC. It is currently impossible to estimate accurately the amount
of further principal payments that BTC might receive in the future.     

     For additional information concerning BTC's investment portfolio, see "BTC
STATISTICAL DATA."

     Liquidity

     Liquidity is the ability to provide sufficient cash flow to meet financial
commitments and to fund additional loan demand or withdrawal of existing
deposits. BTC's primary source of funds are deposits, redemptions and sales of
investment securities, and payments of principal and interest on loans. While
maturities and scheduled principal amortization on loans are a reasonably
predictable source of funds, deposit flows and mortgage loan prepayments are
greatly influenced by the level of interest rates, economic conditions, and
competition.
    
     The primary lending and investment activities of BTC have been the
origination of adjustable rate real estate loans, the purchase of U.S.
government sponsored agency securities and, to a lesser extent, the purchase of
short-term investment such as Fed Funds. Investing activities provide a source
of long and short term liquidity. Lending and investment activities are funded
primarily by principal and interest payments on loans and interest bearing
deposit growth. The major source of funds for BTC's investment activities during
1994 and the first nine months of 1995 was an increase in average deposits of
$5.5 million and $2.3 million in the respective periods.     

                                       90
<PAGE>
 
    
     BTC's most liquid assets are cash, cash in banks and Fed Funds. The levels
of these assets depend on BTC's operating, financing, lending and investing
activities during any given period. At September 30, 1995 and at December 31,
1994 and 1993, these liquid assets totaled $12.3 million, $11.7 million and
$12.9 million, respectively.      

     Liquidity for BTC is monitored on a daily basis and evaluated as a part of
long-term financial strategy. Excess funds are generally invested in Fed Funds.
In the event that BTC should require funds beyond its ability to generate them
internally, additional sources of funds are available through the use of
borrowings against U.S. government sponsored agency securities and through
borrowings from the Federal Reserve's discount window. At September 30, 1995 and
at December 31, 1994 and 1993, BTC had no outstanding borrowings from the
Federal Reserve.

     In the Spring of 1995, BTC became a member of the Federal Home Loan Bank of
Atlanta and eligible to participate in various borrowing programs from such
Bank. In connection with such membership, BTC purchased $537,000 of such Bank's
securities. BTC had no outstanding borrowings from the Federal Home Loan Bank of
Atlanta at September 30, 1995.

     Capital Resources

     BTC continues to maintain a strong capital position with the increase in
total capital attributable to retained earnings. BTC's objective is to maintain
a strong level of capital that will support asset growth, protect against credit
risks and ensure compliance with regulatory and industry standards.

     BTC is subject to certain leverage and risk-based capital adequacy
standards mandated by the Federal Reserve Board. See "CERTAIN REGULATORY
CONSIDERATIONS--NBB and BTC--Capital Requirements." BTC was in compliance with
all such requirements at September 30, 1995 and at December 31, 1994 and 1993.

     The following tables set forth BTC's capital ratios as of the dates 
indicated:

     At September 30, 1995, BTC did not have any material commitments for the
expenditure of its capital.
    
     Dividends on shares of BTC's Common Stock have customarily been paid 
semi-annually on January 2 and July 1 of each year with the dividend actually
declared in the preceding December and June. On January 2, 1995, a cash dividend
of $.80 per share was paid to holders of the then outstanding shares. On
February 1, 1995, BTC paid a stock dividend of 200%. On July 1, 1995, BTC paid a
cash dividend of $.25 per share (as adjusted for the 200% stock dividend). A
cash dividend of $.27 per share was declared in December 1995 and paid on or
about January 2, 1996. Since the dividend was declared in 1995, the amount of
such dividend was accrued against 1995 earnings.      

     Impact of Inflation and Changing Prices

     The financial statements and notes thereto presented herein have been
prepared in accordance with generally accepted accounting principals which
require the measurement of financial position and operating results in terms of
historical dollars without considering the change in the relative purchasing
power of money over time due to inflation. The impact of inflation is reflected
in the increased cost of BTC's operations. Unlike most industrial companies,
nearly all the assets and liabilities of BTC are monetary. As a result, interest
rates have a greater impact on BTC's performance than do the effects of general
levels of inflation. Interest rates do not necessarily move in the same
direction or to the same extent as the prices of goods and services.

     Accounting Considerations

     The FASB has in the last several years issued a number of statements of
financial accounting standards which impact upon the business of banking. The
cumulative effect of the adoption of these changes in accounting standards by
BTC has not been material. For a discussion of the changes in accounting, see 
"--Securities" and "CERTAIN REGULATORY CONSIDERATIONS--Accounting Changes."

     C.  ANALYSIS OF CHANGES IN INTEREST INCOME AND INTEREST EXPENSE

     BTC's primary source of revenue is net interest income, which is the
difference between the interest and fees earned on loans and investments and the
interest paid on deposits and other funds. BTC's net interest income is affected
by changes in the amount and mix of interest-earning assets and interest-bearing
liabilities and by changes in yields earned on interest-earning assets and rates
paid on interest-bearing liabilities. The tables below set forth, for the
periods indicated, a summary of the changes in interest income and interest
expense resulting from changes in average asset and liability balances (volume)
and changes in average interest rate (rate). The change in interest due to both
rate and volume has been allocated equally to change due to volume and change
due to rate. Tax exempt income is presented on a tax equivalent basis.

INTEREST RATE SENSITIVITY

     The tables below set forth, as of the dates indicated, the distribution of
repricing opportunities of BTC's interest-earning assets and interest-bearing
liabilities, the interest rate sensitivity gap (i.e., interest rate sensitive
assets less interest rate sensitive liabilities), the cumulative interest rate
sensitivity gap ratio (i.e., interest rate sensitivity gap divided by total
interest-earning assets) and the cumulative interest rate sensitivity gap ratio.
The tables set forth the time periods during which interest-earning assets and
interest-bearing liabilities will mature or may reprice in accordance with their
contracted terms.

     Certain shortcomings are inherent in the method of analysis presented in
the following tables. For example, although certain assets and liabilities may
have similar maturities or periods of repricing, they may react in different
degrees and at different times to changes in market interest rates. Also, loan
prepayments and early withdrawals of certificates of deposit could cause the
interest sensitivities to vary from those which appear on the tables.
    
     BTC has a formal asset/liability management program. The primary goal of
the program is to provide management with information related to the rate
sensitivity of certain assets and liabilities and the effect of changing rates
on profitability and capital accounts. While this planning process is designed
to protect BTC over the long-term, it does not provide near-term protection from
"interest rate shocks," as interest rate sensitive assets and liabilities do
not, by their nature, move up or down in tandem in response to changes in the
overall rate environment. Therefore, BTC's profitability in the near-term may
temporarily be affected, either positively by a falling interest rate scenario,
or negatively by a period of rising rates.

     An interest rate sensitivity gap is considered positive when the amount of
interest rate sensitive assets exceeds the amount of interest rate sensitive
liabilities. A gap is considered negative when the amount of interest rate
sensitive liabilities exceeds the amount of interest rate sensitive assets.
During a period of rising interest rates, a negative gap would generally tend to
affect adversely net interest income while a positive gap would generally tend
to result in an increase in net interest income. During a period of declining
interest rates, a negative gap would generally tend to result in increased net
interest income while a positive gap would generally tend to affect adversely
net interest income. BTC's future earnings may be adversely affected by a sharp
upturn in interest rates as BTC is liability sensitive for the next twelve
months. In a falling rate environment earnings would benefit to a certain degree
from this position, because assets at higher rate levels would reprice downward
at a slower rate than interest sensitive liabilities. Over the one to five year
period, BTC's cumulative interest-sensitivity position reflects an asset
sensitive position. This would mean BTC would benefit initially from falling
rates, but would benefit in the one to five year period from rising rates. This
would depend, however, on the length of time rates were rising and falling and
the length of time rates remained stable at the level ultimately reached.

     BTC's management is responsible for monitoring loan performance which is
chiefly done through a review of loan delinquencies and personal knowledge of
customers. Loan delinquencies are also reported to and reviewed by the BTC Board
of Directors on a monthly basis. BTC does not maintain a "watch" list nor has it
implemented an internal loan classification process. Except as set forth in the
preceding table, there are no loans which management has serious doubts as to
the borrower's ability to comply with present loan repayment terms.
    
     BTC does not have a formal nonaccrual policy.  A loan is placed on
nonaccrual when, in the judgment of management, it is doubtful that full
principal and interest will be collected. BTC's nonaccrual practice differs from
current industry practice, which requires loans greater than 90 days past due to
be placed on nonaccrual status unless such loans are well-collateralized and in
the process of collection. BTC's management believes that its nonaccrual
practice is adequate in light of the size of BTC's loan portfolio, BTC's limited
loan loss history and management's local and customer knowledge. When loans are
placed on nonaccrual status, all uncollected interest accrued is reversed from
earnings. Once on nonaccrual status, interest on a loan is only recognized on a
cash basis. Loans may be returned to accrual status if management believes that
all remaining principal and interest is fully collectible and there has been at
least six months of sustained repayment performance since the loan was placed on
nonaccrual.     

     If a loan's credit quality deteriorates to the point that collection
of principal is believed by management to be doubtful and the value of
collateral securing the obligation is insufficient, BTC generally takes steps to
protect and liquidate the collateral. Any loss resulting from the difference
between the loan balance and the fair market value of the property is recognized
by a charge to the allowance for loan losses. When the property is held for sale
after foreclosure, it is subject to periodic appraisal. If the appraisal
indicates that the property will sell for less than its recorded value, BTC
recognizes the loss by a charge to noninterest expense.

IV.  SUMMARY OF LOAN LOSS EXPERIENCE

     A.   ANALYSIS OF THE ALLOWANCE FOR LOAN LOSSES

     BTC maintains an allowance for loan losses that is increased by
provisions charged against earnings and reduced by net loan charge-offs. Loans
are charged off when they are deemed to be uncollectible, or partially charged
off when portions of a loan are deemed uncollectible. Recoveries are generally
recorded only when cash payments are received.

     The following table provides certain information with respect to BTC's
allowance for loan losses as well as charge-offs and recoveries for the periods
indicated:

     BTC's allowance for loan losses at December 31, 1995 was $545,000. The
determination of this allowance requires the use of estimates and assumptions
regarding the risks inherent in individual loans and the loan portfolio in its
entirety. In addition, regulatory agencies periodically review and may require
BTC to make additions to its allowance for loan losses. While BTC's management
believes these estimates and assumptions are reasonable, no assurance can be
given that they will not be proven incorrect in the future.      

     B.   ALLOCATION OF THE ALLOWANCE FOR LOAN LOSSES
    
     The allowance for loan losses has been allocated according to the amount
deemed necessary to provide for anticipated losses within the categories of
loans as of December 31, 1995, 1994 and 1993 as follows:

Committees of the BTC Board

     BTC does not have a standing Nominating Committee or Compensation
Committee. The following paragraphs set forth information concerning certain
committees of the BTC Board of Directors and their respective members.

     The Audit Committee is comprised of Messrs. Greever (Chairman), Deskins,
Green, Bailey and Pope. During 1994, this Committee met once. It has met twice
during 1995. The Audit Committee establishes audit policy, reviews and approves
the audit plan of the internal auditor, evaluates the effectiveness of the
internal and external auditors, determines any restrictions on the scope of the
internal auditor, meets with the internal auditor to discuss reports and
concerns, evaluates BTC's accounting policies, evaluates BTC's system of
internal controls and risk assessment through the analyses performed by the
internal auditor, reviews regulatory agency reports and management's responses
thereto, reviews and approves the annual financial statements and the external
auditor's management letter and reports to the Board of Directors.

     The Finance Committee is comprised of Messrs. Bowen (Chairman), Dodson,
Peery, Pope, VanDyke and Carl C. Gillespie. During 1994, this Committee met
three times. It has met three times during 1995. The Finance Committee reviews
and approves loans. It also serves as an executive committee in the absence of
the Board of Directors.

     During 1994, the BTC Board met twelve times. No director attended less than
75% of the aggregate of (i) the total number of meetings of the BTC Board; and
(ii) the total number of meetings held by all committees of the BTC Board on
which such director served during 1994.

(1) This amount includes fees paid to Mr. Dodson as a director of BTC.

(2) This amount reflects the 14.14% bonus paid to all personnel of BTC.

(3) This amount reflects nine months of pension benefits (commencing on
    April 1, 1995) paid to Mr. Dodson pursuant to BTC's Employees' Pension
    Plan.  The Bank provides Mr. Dodson with an automobile for his use.  No
    amount is stated as the amount of any personal usage by Mr. Dodson.  BTC is
    reimbursed by Mr. Dodson for any personal use on a yearly basis.

Director Compensation

     Directors of BTC are paid fees of $300 per meeting for their services as
directors, including attendance at regular and special BTC Board meetings and
committee meetings. There were $51,400 in directors fees paid during 1994. No
additional fees are paid for attendance at special Board meetings or committee
meetings.

Pension Plan

     BTC maintains a tax-qualified pension plan for qualified employees under
the Bank of Tazewell County Employees' Pension Plan (the "BTC Plan"). The BTC
Plan was initially effective on October 20, 1965, but was amended in its
entirety effective October 20, 1989. The BTC Plan covers all officers and
employees who, as of April 20 or October 20 of any year, have reached the age of
twenty-one and who have had one year of service. BTC is required under the BTC
Plan to make contributions to a related trust in such amounts as are estimated
to be sufficient to provide the required benefits under such Plan determined on
an actuarially sound basis. Officers and employees are not permitted to make
contributions to the BTC Plan. Benefits generally commence on the later of a
participant reaching age 65 or the date on which the participant completes five
years of participation in the BTC Plan. The normal form of benefit is a monthly
pension payable during the participant's lifetime with a minimum of 120 monthly
payments, but other payment options may be elected under certain circumstances.
In general, the standard monthly pension benefit is equal to the sum of (i) 1.5%
of "plan compensation" multiplied by the years of credited service (but not in
excess of 35 years) at normal retirement date, plus (ii) .59% of "plan
compensation" in excess of $800 multiplied by the years of credited service (but
not in excess of 35 years). "Plan compensation" is 

                                      107
<PAGE>
 
equal to the highest monthly average obtained from the sum of any of a
participant's five annual compensation amounts divided by the number of months
such participant was compensated during such period. For purposes of such
calculation, annual compensation may not exceed $200,000.

     The following table shows the estimated annual benefits payable from the
BTC Plan upon retirement on specific compensation and years of service
classification, assuming continuation of the BTC Plan in its present form:

     Mr. Dodson's benefits under the BTC Plan are fully vested and funded. Mr.
Dodson began receiving a monthly benefit of $4,812 on April 1, 1994, which is in
addition to his salary at BTC.

Certain Relationships and Related Transactions Regarding BTC

     Certain of the directors and executive officers of BTC, the companies
or organizations with which they are affiliated, and members of their immediate
families are customers of, and had banking transactions with BTC in the ordinary
course of BTC's business during 1994, and BTC expects to have banking
transactions with such persons in the future. All loans and commitments to lend
to such persons were made on substantially the same terms, including interest
rates, repayment terms and collateral, as those prevailing at the time for
comparable transactions with other persons of similar creditworthiness and, in
the opinion of management of BTC, did not involve more than a normal risk of
collectibility or present other unfavorable features.

     During 1994, the law firm of Bowen, Bowen & Bowen, P.C., of which T. C.
Bowen, Chairman of the Board of BTC, is a partner, provided legal services to
BTC in the amount of $10,000. Such amount exceeded 5% of such firm's gross
revenues in 1994. It is anticipated that such firm will continue to provide
legal services to BTC in the future.


                       CERTAIN REGULATORY CONSIDERATIONS

     NBI, NBB and BTC are subject to various state and federal banking laws
and regulations which impose specific requirements or restrictions on and
provide for general regulatory oversight with respect to virtually all aspects
of operations. As a result of the substantial regulatory burdens on banking,
financial institutions, including NBI, NBB and BTC, are disadvantaged relative
to other competitors who are not as highly regulated, and their costs of doing
business are much higher. The following is a brief summary of the material
provisions of certain statutes, rules and regulations which affect NBI, NBB
and/or BTC and, if the Merger is consummated, will affect BTC. This summary is
qualified in its entirety by reference to the particular statutory and
regulatory provisions referred to below and is not intended to be an exhaustive
description of the statutes or regulations which are applicable to the
businesses of NBI, NBB and/or BTC. Any change in applicable laws or regulations
may have a material adverse effect on the business and prospects of NBI, NBB
and/or BTC.

                                      108
<PAGE>
 
NBI

     NBI is a bank holding company within the meaning of the BHCA and Chapter 13
of the Virginia Banking Act, as amended (the "Virginia Banking Act"). The
activities of NBI also are governed by the Glass-Steagall Act of 1933 (the
"Glass-Steagall Act").

     The BHCA. The BHCA is administered by the Federal Reserve Board, and NBI is
required to file with the Federal Reserve Board an annual report and such
additional information as the Federal Reserve Board may require pursuant to the
BHCA. The Federal Reserve Board also is authorized to examine NBI and its
subsidiaries. The BHCA requires every bank holding company to obtain the prior
approval of the Federal Reserve Board before (i) it or any of its subsidiaries
(other than a bank) acquires substantially all the assets of any bank; (ii) it
acquires ownership or control of any voting shares of any bank if after such
acquisition it would own or control, directly or indirectly, more than 5% of the
voting shares of such bank; or (iii) it merges or consolidates with any other
bank holding company.

     The BHCA and the Change in Bank Control Act, together with regulations
promulgated by the Federal Reserve Board, require that, depending on the
particular circumstances, either Federal Reserve Board approval must be obtained
or notice must be furnished to the Federal Reserve Board and not disapproved
prior to any person or company acquiring "control" of a bank holding company,
such as NBI, subject to certain exemptions for certain transactions. Control is
conclusively presumed to exist if an individual or company acquires 25% or more
of any class of voting securities of NBI. Control is rebuttably presumed to
exist if a person acquires 10% or more, but less than 25%, of any class of
voting securities of NBI. The regulations provide a procedure for challenging
the rebuttable control presumption.

     Under the BHCA, a bank holding company is generally prohibited from
engaging in, or acquiring direct or indirect control of more than 5% of the
voting shares of any company engaged in, nonbanking activities, unless the
Federal Reserve Board, by order or regulation, has found those activities to be
so closely related to banking or managing or controlling banks as to be a proper
incident thereto. Some of the activities that the Federal Reserve Board has
determined by regulation to be proper incidents to the business of a bank
holding company include making or servicing loans and certain types of leases,
engaging in certain insurance and discount brokerage activities, performing
certain data processing services, acting in certain circumstances as a fiduciary
or investment or financial adviser, owning savings associations and making
investments in certain corporations or projects designed primarily to promote
community welfare.

     The Federal Reserve Board imposes certain capital requirements on NBI under
the BHCA, including a minimum leverage ratio and a minimum ratio of "qualifying"
capital to risk-weighted assets. These requirements are described below under 
"--Capital Requirements." Subject to its capital requirements and certain other
restrictions, NBI can borrow money to make a capital contribution to NBB and, if
the Merger is consummated, to BTC, and such loans may be repaid from dividends
paid from NBB and BTC to NBI (although the ability of NBB and BTC to pay
dividends are subject to regulatory restrictions as described below in "--NBB
and BTC--Limits on Dividends and Other Payments"). NBI can raise capital for
contribution to NBB and BTC by issuing securities without having to receive
regulatory approval, subject to compliance with federal and state securities
laws.

     The Virginia Banking Act. All Virginia bank holding companies must register
with the Virginia Commission under the Virginia Banking Act. A registered bank
holding company must provide the Virginia Commission with information with
respect to the financial condition, operations, management and intercompany
relationships of the holding company and its subsidiaries. The Virginia
Commission also may require such other information as is necessary to keep
itself informed about whether the provisions of Virginia law and the regulations
and orders issued thereunder by the Virginia Commission have been complied with,
and may make examinations of any bank holding company and its subsidiaries.

     In March 1994, the Virginia General Assembly adopted an amendment to
Chapter 15 of the Virginia Banking Act to allow bank holding companies located
in any state to acquire a Virginia bank or bank holding 

                                      109
<PAGE>
 
company if the Virginia bank or bank holding company could acquire a bank
holding company in their state and the Virginia bank or bank holding company to
be acquired has been in existence and continuously operated for more than two
years. This amendment may permit bank holding companies from throughout the
United States to enter the Virginia market, subject to federal and state
approval. See "NBB and BTC--Branching."

     Glass-Steagall Act. NBI also is restricted in its activities by the
provisions of the Glass-Steagall Act, which prohibit NBI from owning
subsidiaries that are engaged principally in the issue, flotation, underwriting,
public sale or distribution of securities. The interpretation, scope and
application of the provisions of the Glass-Steagall Act currently are being
considered and reviewed by regulators and legislators, and the interpretation
and application of those provisions have been challenged in the federal courts.
NBI does not presently engage in securities-related activities in any material
respect.

NBB and BTC

     General. NBB, NBI's sole operating subsidiary, is a national banking
association incorporated under the laws of the United States and is subject to
examination by the Office of the Comptroller of the Currency (the "OCC").
Deposits in NBB are insured by the FDIC up to a maximum amount (generally
$100,000 per depositor, subject to aggregation rules). The OCC and the FDIC
regulate or monitor all areas of NBB's operations, including security devices
and procedures, adequacy of capitalization and loss reserves, loans,
investments, borrowings, deposits, mergers, issuances of securities, payment of
dividends, interest rates payable on deposits, interest rates or fees chargeable
on loans, establishment of branches, corporate reorganizations and maintenance
of books and records. The OCC requires NBB to maintain certain capital ratios.
NBB is required by the OCC to prepare quarterly reports on NBB's financial
condition and to conduct an annual audit of its financial affairs in compliance
with minimum standards and procedures prescribed by the OCC. NBB also is
required by the OCC to adopt internal control structures and procedures in order
to safeguard assets and monitor and reduce risk exposure. While appropriate for
safety and soundness of banks, these requirements impact banking overhead costs.

     BTC is, and, if the Merger is consummated, BTC will continue to be,
organized as a Virginia-chartered banking corporation and is and will be
regulated and supervised by the BFI of the Virginia Commission. In addition, as
a federally insured bank, BTC is regulated and supervised by the Federal Reserve
Board, which serves as its primary federal regulator, and is subject to certain
regulations promulgated by the FDIC. Under the provisions of federal law,
federally insured banks are subject, with certain exceptions, to certain
restrictions on extensions of credit to their affiliates, on investments in the
stock or other securities of affiliates and on the taking of such stock or
securities as collateral from any borrower. In addition, such banks are
prohibited from engaging in certain tie-in arrangements in connection with any
extension of credit or the providing of any property or service.

     The Virginia Commission and the Federal Reserve Board conduct regular
examinations of BTC reviewing the adequacy of the loan loss reserves, quality of
the loans and investments, propriety of management practices, compliance with
laws and regulations, and other aspects of the bank's operations. In addition to
these regular examinations, Virginia chartered banks must furnish to the Federal
Reserve Board quarterly reports containing detailed financial statements and
schedules.

     Community Reinvestment Act. NBB and BTC are subject to the provisions of
the Community Reinvestment Act of 1977 (the "CRA"), which require the
appropriate federal bank regulatory agency, in connection with its regular
examination of a bank, to assess the bank's record in meeting the credit needs
of the community served by the bank, including low and moderate-income
neighborhoods. The banking regulators recently have substantially overhauled the
implementing CRA regulations. Under the new regulations, banks will have the
option of being assessed for CRA compliance under one of several methods. Small
banks will be evaluated differently than larger banks and technically are not
subject to some data collection requirements. The focus of the new regulations
is on the volume and distribution of a bank's loans, with particular emphasis on
lending activity in low and moderate-income areas and to low and moderate-income
persons. The new regulations place added importance on a bank's product delivery
system, particularly branch localities. The new regulations will require banks,
other than small banks, to comply with significantly increased data collection
requirements. The regulatory agency's assessment of 

                                      110
<PAGE>
 
the bank's record is made available to the public. Further, such assessment is
required for any bank which has applied to, among other things, establish a new
branch office that will accept deposits, relocate an existing office, or merge,
consolidate with or acquire the assets or assume the liabilities of a federally
regulated financial institution. It is likely that banks' compliance with the
CRA, as well as other so-called fair lending laws, will face heightened
government scrutiny and that costs associated with compliance will increase.

    
     NBB and BTC received CRA ratings of "Outstanding" and "Satisfactory,"
respectively, in their last examinations by their primary federal bank
regulators.     

     Branching. In 1986, the Virginia Banking Act was amended to remove the
geographic restrictions governing the establishment of branch banking offices.
Subject to the approval of the appropriate federal and state bank regulatory
authorities, BTC may establish a branch office anywhere in Virginia.

     National banks, like NBB, are required by the National Bank Act to adhere
to branch banking laws applicable to state banks in the states in which they are
located. Under current Virginia law, NBB may open branch offices throughout
Virginia with the prior approval of the OCC. In addition, with prior approval of
one or more of the Federal Reserve Board, the Virginia Commission, the OCC and
the FDIC, NBB will be able to acquire existing banking operations in Virginia.
NBB currently has no plans or agreements whereby NBB would acquire other banks
or thrifts.

     On September 29, 1994, President Clinton signed into law the Riegle-Neal
Interstate Banking and Branching Efficiency Act of 1994 (the "Interstate Act").
The Interstate Act, which became effective September 29, 1995, allows bank
holding companies to acquire banks in any state, without regard to state law,
except that if the state has a minimum requirement for the amount of time a bank
must be in existence, that law must be preserved. Under the Virginia Banking
Act, a Virginia bank or all of the subsidiaries of Virginia holding companies
sought to be acquired must have been in continuous operation for more than two
years before the date of such proposed acquisition. See "--NBI--The Virginia
Banking Act." The Interstate Act permits banks to acquire out-of-state branches
through interstate mergers, beginning June 1, 1997. States can opt-in to
interstate branching earlier, or opt-out before June 1, 1997. De novo branching,
where an out-of-state bank holding company sets up a new branch in another
state, would require a state's specific approval. An acquisition or merger would
not be permitted under the Interstate Act if the bank, including its insured
depository affiliates, would control more than 10% of the total amount of
deposits of insured depository institutions in the United States, or would
control 30% or more of the total amount of deposits of insured depository
institutions in any state.

     Virginia has, by statute, elected to "opt-in" fully to interstate branching
under the Interstate Act, effective July 1, 1995. Under the Virginia statute,
Virginia state banks may, with the approval of the Virginia Commission,
establish and maintain a de novo branch or acquire one or more branches in a
state other than Virginia, either separately or as part of a merger. Procedures
also are established to allow out-of-state domiciled banks to establish or
acquire branches in Virginia, provided the "home" state of the bank permits
Virginia banks to establish or acquire branches within its borders. The
activities of such branches would be subject to the same laws as Virginia
domiciled banks, unless such activities are prohibited by the law of the state
where the bank is organized. The Virginia Commission would have the authority to
examine and supervise out-of-state state banks to ensure that the branch is
operating in a safe and sound manner and in compliance with the laws of
Virginia. The Virginia statute authorizes the BFI to enter into cooperative
agreements with other state and federal regulators for the examination and
supervision of out-of-state state banks with Virginia operations, or Virginia
domiciled banks with operations in other states. Likewise, national banks, with
the approval of the OCC, may branch into and out of the state of Virginia. Any
Virginia branch of an out-of-state national bank is subject to Virginia law
(enforced by the OCC) with respect to intrastate branching, consumer protection,
fair lending and community reinvestment as if it were a branch of a Virginia
bank, unless preempted by federal law.

     The Interstate Act will permit banks and bank holding companies throughout
the United States to enter Virginia markets through the acquisition of Virginia
institutions and will make it easier for Virginia bank holding companies and
Virginia state and national banks to acquire institutions and to establish
branches in other states. 

                                      111
<PAGE>
 
Competition in market areas served by NBI, NBB and BTC may increase as a result
of the Interstate Act and the Virginia interstate banking statutes.

     Deposit Insurance. NBB and BTC are subject to FDIC deposit insurance
assessments. See "--Legislative Developments--Deposit Insurance."

     Governmental Policies. The operations of NBB and BTC are affected not only
by general economic conditions, but also by the policies of various regulatory
authorities. In particular, the Federal Reserve Board regulates money and credit
and interest rates in order to influence general economic conditions. These
policies have a significant influence on overall growth and distribution of
loans, investments and deposits and affect interest rates charged on loans or
paid for time and savings deposits. Federal Reserve Board monetary policies have
had a significant effect on the operating results of commercial banks in the
past and are expected to continue to do so in the future.

     Limits on Dividends and Other Payments. As a national bank, NBB, may not
pay dividends from its capital; all dividends must be paid out of net profits
then on hand, after deducting expenses, losses, bad debts, accrued dividends on
preferred stock, if any, and taxes. In addition, a national bank is prohibited
from declaring a dividend on its shares of common stock until its surplus equals
its stated capital, unless there has been transferred to surplus no less than
one-tenth of the bank's net profits of (i) the preceding two consecutive half-
year periods (in the case of an annual dividend) or (ii) the preceding half-year
period (in the case of a quarterly or semi-annual dividend). The approval of the
OCC is required if the total of all dividends declared by a national bank in any
calendar year exceeds the total of its net profits for that year combined with
its retained net profits for the preceding two years, less any required
transfers to surplus or to fund the retirement of preferred stock. At September
30, 1995, retained net profits available for NBB dividends were approximately
$5,715,000.

     The OCC has promulgated regulations that became effective on December 13,
1990, which significantly affect the level of allowable dividend payments for
national banks. The effect is to make the calculation of national banks'
dividend-paying capacity consistent with generally accepted accounting
principles. The allowance for loan and lease losses will not be considered an
element of "undivided profits then on hand" and provisions to the allowance are
treated as expenses and therefore not part of "net profits." Accordingly, a
national bank with an allowance greater than its statutory bad debts may not
include the excess in calculating undivided profits for dividend purposes.
Further, a national bank may be able to use a portion of its earned capital
surplus account as "undivided profits then on hand," depending on the
composition of that account.

     As a state member bank subject to the regulations of the Federal Reserve
Board, BTC must obtain the approval of the Federal Reserve Board for any
dividend if the total of all dividends declared in any calendar year would
exceed the total of its net profits, as defined by the Federal Reserve Board,
for that year, combined with its retained net profits for the preceding two
years. In addition, a state member bank may not pay a dividend in an amount
greater than its undivided profits then on hand after deducting its losses and
bad debts. For this purpose, bad debts are generally defined to include the
principal amount of loans which are in arrears with respect to interest by six
months or more, unless such loans are fully secured and in the process of
collection. Moreover, for purposes of this limitation, a state member bank is
not permitted to add the balance in its allowance for loan losses account to its
undivided profits then on hand; however, it may net the sum of its bad debts as
so defined against the balance in its allowance for loan losses account and
deduct from undivided profits only bad debts as so defined in excess of that
account. At September 30, 1995, BTC had retained earnings of $3,426,000 which
were legally available for the payment of dividends.

     In addition, the Federal Reserve Board is authorized to determine, under
certain circumstances relating to the financial condition of a state member
bank, that the payment of dividends would be an unsafe or unsound practice and
to prohibit payment thereof. The payment of dividends that depletes a bank's
capital base could be deemed to constitute such an unsafe or unsound practice.
The Federal Reserve Board has indicated that banking organizations should
generally pay dividends only out of current operating earnings.

                                      112
<PAGE>
 
     Virginia law also imposes restrictions on the ability of BTC to pay
dividends. A Virginia state bank is permitted to declare a dividend out of its
"net undivided profits," after providing for all expenses, losses, interest and
taxes accrued or due by the bank. In addition, a deficit in capital originally
paid in must be restored to its initial level, and no dividend can be paid which
could impair the bank's paid in capital. The BFI further has authority to limit
the payment of dividends by a Virginia bank if it determines the limitation is
in the public interest and is necessary to ensure the bank's financial
soundness.

     The Federal Deposit Insurance Corporation Improvement Act of 1991
("FDICIA") provides that no insured depository institution may make any capital
distribution (which would include a cash dividend) if, after making the
distribution, the institution would not satisfy one or more of its minimum
capital requirements. See "--Capital Requirements" below.

     Capital Requirements. The Federal Reserve Board has adopted risk-based
capital guidelines in final form which are applicable to NBI and BTC. The
Federal Reserve Board guidelines redefine the components of capital, categorize
assets into different risk classes and include certain off-balance sheet items
in the calculation of risk-weighted assets. The minimum ratio of qualified total
capital to risk-weighted assets (including certain off-balance sheet items, such
as standby letters of credit) is 8.0%. At least half of the total capital must
be comprised of Tier 1 capital. The remainder may consist of a limited amount of
subordinated debt, other preferred stock, certain other instruments and a
limited amount of loan and lease loss reserves. The OCC has adopted similar
regulations applicable to NBB. The Tier 1 and total risk-based capital ratios of
NBI as of September 30, 1995, were 14.91% and 16.16%, respectively. NBB's Tier 1
and total risk-based capital ratios as of September 30, 1995, were 14.21% and
15.46%, respectively. BTC's Tier 1 and total risk-based capital ratios as of
September 30, 1995, were 42.01% and 42.92%, respectively.

     In addition, the Federal Reserve Board has established minimum leverage
ratio (Tier 1 capital to total assets less intangibles) guidelines that are
applicable to NBI and BTC. The OCC has adopted similar regulations applicable to
NBB. These guidelines provide for a minimum ratio of 3.0% for banks that meet
certain specified criteria, including that they have the highest regulatory
rating. All other banks will be required to maintain a leverage ratio of 4.0% or
greater, based upon their particular circumstances and risk profiles. NBI's,
NBB's and BTC's leverage ratios, as of September 30, 1995, were 10.25%, 9.76%
and 14.54%, respectively. The guidelines also provide that banks experiencing
internal growth or making acquisitions will be expected to maintain strong
capital positions substantially above the minimum supervisory levels, without
significant reliance on intangible assets.

     Bank regulators from time to time have indicated a desire to raise capital
requirements applicable to banking organizations beyond current levels. In
addition, the number of risks which may be included in risk-based capital
restrictions, as well as the measurement of these risks, is likely to change,
resulting in increased capital requirements for banks. NBI, NBB and BTC are
unable to predict whether higher capital ratios would be imposed and, if so, at
what levels and on what schedule.

Legislative Developments

     The difficulties encountered nationwide by financial institutions during
1990 and 1991 prompted federal legislation designed to reform the banking
industry and to promote the viability of the industry and of the deposit
insurance system. FDICIA, which became effective on December 19, 1991, bolsters
the deposit insurance fund, tightens bank regulation and trims the scope of
federal deposit insurance as summarized below.

     FDIC Funding. The legislation bolsters the bank deposit insurance fund with
$70 billion in borrowing authority and increases to $30 billion from $5 billion
the amount the FDIC can borrow from the U.S. Treasury to cover the cost of bank
failures. The loans, plus interest, would be repaid by premiums that banks pay
on domestic deposits over the next fifteen years.

     Prompt Corrective Action. Among other things, FDICIA requires the federal
banking agencies to take "prompt corrective action" in respect of banks that do
not meet minimum capital requirements. FDICIA establishes 

                                      113
<PAGE>
 
five capital tiers: "well capitalized," "adequately capitalized,"
"undercapitalized," "significantly undercapitalized" and "critically
undercapitalized." The following table sets forth the minimum capital ratios
that a bank must satisfy in order to be considered well capitalized or
adequately capitalized under Federal Reserve Board regulations. See "NBI'S
MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF
OPERATIONS--Capital Adequacy" for information on NBB's capital ratios and see
"BTC'S MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
OF OPERATIONS--Capital Resources" for a discussion of BTC's capital ratios.

Leverage Ratio                               4%            5%
</TABLE>

     If a bank does not meet all of the minimum capital ratios necessary to be
considered adequately capitalized, it will be considered undercapitalized,
significantly undercapitalized or critically undercapitalized, depending on the
amount of the shortfall in its capital.

     If a depository institution's principal federal regulator determines that
an otherwise adequately capitalized institution is in an unsafe or unsound
condition or is engaging in an unsafe or unsound practice, it may require the
institution to submit a corrective action plan, restrict its asset growth and
prohibit branching, new acquisitions and new lines of business. An institution's
principal federal regulator may deem the institution to be engaging in an unsafe
or unsound practice if it receives a less than satisfactory rating for asset
quality, management, earnings or liquidity in its most recent examination.

     Among other possible sanctions, an undercapitalized depository institution
may not pay dividends and is required to submit a capital restoration plan to
its principal federal regulator. In addition, its holding company may be
required to guarantee compliance with the capital restoration plan under certain
circumstances. If an undercapitalized depository institution fails to submit or
implement an acceptable capital restoration plan, it can be subjected to more
severe sanctions, including an order to sell sufficient voting stock to become
adequately capitalized. More severe sanctions and remedial actions can be
mandated by the regulators if an institution is considered significantly or
critically undercapitalized.

     In addition, FDICIA requires regulators to draft a new set of non-capital
measures of bank safety, such as loan underwriting standards and minimum
earnings levels. The legislation also requires regulators to perform annual on-
site bank examinations, places limits on real estate lending by banks and
tightens auditing requirements. In April 1995, the regulators adopted safety and
soundness standards as required by FDICIA in the following areas: (i)
operational and managerial; (ii) asset quality earnings and stock valuation; and
(iii) employee compensation.

     Deposit Insurance. FDICIA reduces the scope of federal deposit insurance.
The most significant change ended the "too big to fail" doctrine, under which
the government protects all deposits in most banks, including those exceeding
the $100,000 insurance limit. The FDIC's ability to reimburse uninsured 
deposits--those over $100,000 and foreign deposits--has been sharply limited.
Since December 1993, the Federal Reserve Board's ability to finance
undercapitalized banks with extended loans from its discount window has been
restricted. In addition, only the best capitalized banks will be able to offer
insured brokered deposits without FDIC permission or to insure accounts
established under employee pension plans.

     The FDIC establishes rates for the payment of premiums by federally insured
banks for deposit insurance. A Bank Insurance Fund (the "BIF") is maintained for
commercial banks, with insurance premiums from the industry used to offset
losses from insurance payouts when banks fail. Beginning in 1993, insured
depository institutions like NBB and BTC pay for deposit insurance under a risk-
based premium system. Under this system, a depository institution pays to the
BIF from $.23 to $.31 per $100 of insured deposits depending on its capital
levels and risk 

                                      114
<PAGE>
 
profile, as determined by its primary federal regulator on a semi-annual basis.
The FDIC, effective September 15, 1995, lowered assessments from their current
rates of $.23 to $.31 per $100 of insured deposits to rates of $.04 to $.31,
depending on the health of the bank, as a result of the recapitalization of the
BIF. On November 14, 1995, the FDIC voted to drop its premiums for well
capitalized banks to zero effective January 1, 1996. Other banks will be charged
risk-based premiums up to $.27 per $100 of deposits. Both NBI and BTC are
expected to qualify for the zero premium rate in 1996.

     Congress also is expected to act soon on provisions to strengthen the
Savings Association Insurance Fund (the "SAIF") and to repay outstanding bonds
that were issued to recapitalize the SAIF's successor as a result of payments
made due to the insolvency of savings and loan associations and other federally
insured savings institutions in the late 1980s and early 1990s. Costs for these
measures could be passed along, in part, to the banking industry.

     Many of the provisions of FDICIA did not become effective until December
1993. In addition, many of the provisions will be implemented through the
adoption of regulations by the various federal banking agencies. The precise
effect of the legislation on NBI, NBB and BTC cannot be assessed at this time,
and there can be no assurance that such regulations will not materially affect
operating results, financial condition or liquidity of NBI, NBB and/or BTC.

     Other legislative and regulatory proposals regarding changes in banking and
the regulation of banks, thrifts and other financial institutions are being
considered by the executive branch of the federal government, Congress and
various state governments, including Virginia. Certain of these proposals, if
adopted, could significantly change the regulation of banks and the financial
services industry. It cannot be predicted whether any of these proposals will be
adopted or, if adopted, how these proposals will affect NBI, NBB and/or BTC.

Accounting Changes

     In February 1992, the FASB issued SFAS No. 109, "Accounting for Income
Taxes," which superseded SFAS No. 96 of the same title. SFAS No. 109, which
became effective for fiscal years beginning after December 31, 1992, employs an
asset and liability approach in accounting for income taxes payable or
refundable at the date of the financial statements as a result of all events
that have been recognized in the financial statements and as measured by the
provisions of enacted tax laws. Adoption by NBI and BTC of SFAS No. 109 did not
have a material impact on NBI's or BTC's results of operations.

     In December 1991, the FASB issued SFAS No. 107, "Disclosures about Fair
Value of Financial Instruments," which is effective for fiscal years ending
after December 15, 1992 (December 15, 1995, in the case of entities with less
than $150 million in total assets). SFAS No. 107 requires financial
intermediaries to disclose, either in the body of their financial statements or
in the accompanying notes, the "fair value" of financial instruments for which
it is "practicable to estimate that value." SFAS No. 107 defines "fair value" as
the amount at which a financial instrument could be exchanged in a current
transaction between willing parties, other than in a forced or liquidation sale.
Quoted market prices, if available, are deemed the best evidence of the fair
value of such instruments. Most deposit and loan instruments issued by financial
intermediaries are subject to SFAS No. 107, and its effect will be to require
financial statement disclosure of the fair value of most of the assets and
liabilities of financial intermediaries such as BTC and NBB. Management is
unable to predict what effect, if any, such disclosure requirements could have
on the market prices of the common stock of NBI or BTC or their abilities to
raise funds in the financial markets.

     In May 1993, the FASB issued SFAS No. 114, "Accounting by Creditors for
Impairment of a Loan". SFAS No. 114 prescribes the recognition criterion for
loan impairment and the measurement methods for certain impaired loans and loans
whose terms are modified in troubled debt restructurings. SFAS No. 114 states
that a loan is impaired when it is probable that a creditor will be unable to
collect all principal and interest amounts due according to the contracted terms
of the loan agreement. A creditor is required to measure impairment by
discounting expected future cash flows at the loan's effective interest rate, or
by reference to an observable market price, or by determining that foreclosure
is probable. SFAS No. 114 also clarifies the existing accounting for in-
substance foreclosures by 

                                      115
<PAGE>
 
stating that a collateral-dependent real estate loan would be reported as real
estate owned only if the lender had taken possession of collateral.

     SFAS No. 118 amended SFAS No. 114, to allow a creditor to use existing
methods for recognizing interest income on an impaired loan. To accomplish that,
it eliminated the provisions in SFAS No. 114 that described how a creditor
should report income on an impaired loan. SFAS No. 118 did not change the
provisions in SFAS No. 114 that require a creditor to measure impairment based
on the present value of expected future cash flows discounted at the loan's
effective interest rate, or as a practical expedient, at the observable market
price of the loan or the fair value of the collateral if the loan is collateral
dependent. SFAS No. 118 amends the disclosure requirements in SFAS No. 114 to
require information about the recorded investments in certain impaired loans and
about how a creditor recognizes interest income related to those impaired loans.
SFAS No. 114 is effective for financial statements issued for fiscal years
beginning after December 15, 1994. Although earlier application is encouraged,
it is not required.

     In May 1993, the FASB issued SFAS No. 115 "Accounting For Certain
Investments in Debt and Equity Securities" addressing the accounting and
reporting for investments in equity securities that have readily determinable
fair values and for all investments in debt securities. These investments would
be classified in three categories and accounted for as follows: (i) debt and
equity securities that the entity has the positive intent and ability to hold to
maturity would be classified as "held to maturity" and reported at amortized
cost; (ii) debt and equity securities that are held for current resale would be
classified as trading securities and reported at fair value, with unrealized
gains and losses included in operations; and (iii) debt and equity securities
not classified as either securities held to maturity or trading securities would
be classified as securities available for sale, and reported at fair value, with
unrealized gains and losses excluded from operations and reported as a separate
component of stockholders' equity. The statement is effective for financial
statements for calendar year 1994, but may be applied to an earlier fiscal year
for which annual financial statements have not been issued. BTC adopted SFAS No.
115 effective December 31, 1993, and NBI adopted SFAS No. 115 effective January
1, 1994. The cumulative effect of the change in accounting was not material to
either NBI or BTC.


                       DESCRIPTION OF NBI CAPITAL STOCK

     The descriptive information supplied herein outlines certain provisions of
the Articles and Bylaws of NBI and the Virginia Act. The information does not
purport to be complete and is qualified in all respects by reference to the
provisions of NBI's Articles and Bylaws and the Virginia Act.

Authorized Capital
    
     The authorized capital stock of NBI consists of 5,000,000 shares of NBI
common stock, $2.50 par value ("NBI Common Stock"), and 5,000,000 shares of
preferred stock, no par value per share ("NBI Preferred Stock"). As of December
31, 1995, there were 1,714,152 shares of NBI Common Stock, and no shares of NBI
Preferred Stock issued and outstanding.    
    
     The Merger Agreement provides that NBI will, prior to the Merger Effective
Date, increase the number of shares of NBI Common Stock issued and outstanding
by means of a stock dividend totaling 190,768 shares of NBI Common Stock;
provided certain conditions are satisfied. See "THE MERGER--NBI Stock Split."
Giving effect to the NBI Stock Split, 1,904,920 shares of NBI Common Stock will
be issued and outstanding immediately prior to the Merger Effective Date.    

NBI Common Stock

     Subject to the prior rights of the holders of any NBI Preferred Stock,
holders of NBI Common Stock are entitled to receive such dividends as may be
declared by the Board of Directors out of funds legally available therefor and,
in the event of liquidation or dissolution, to receive the net assets of NBI
remaining after payment of all 

                                      116
<PAGE>
 
liabilities and after payment to holders of all shares of NBI Preferred Stock of
the full preferential amounts to which such holders are respectively entitled,
in proportion to their respective holdings.

     See "CERTAIN REGULATORY CONSIDERATIONS--NBB and BTC--Limits on Dividends
and Other Payments" for information relating to certain regulatory restrictions
on the payment of dividends by national banks, including NBI's subsidiary
national bank, NBB.

     Subject to the rights of the holders of any NBI Preferred Stock then
outstanding, all voting rights are vested in the holders of the shares of NBI
Common Stock, each share being entitled to one vote on all matters requiring
stockholder action and in the election of directors. Holders of NBI Common Stock
have no preemptive, subscription or conversion rights. All of the outstanding
shares of NBI Common Stock are fully paid and nonassessable, and the NBI Common
Shares issuable to the stockholders of BTC upon consummation of the Merger will,
upon issuance, be fully paid and nonassessable.

NBI Preferred Stock

     The NBI Board of Directors is authorized to issue shares of NBI Preferred
Stock from time to time in one or more series and to fix and determine the
relative preferences, privileges, limitations and rights of the shares of any
series, including dividend rights and dividend rates, voting rights, liquidation
price, redemption rights and redemption prices, sinking fund requirements and
conversion rights. Each series of NBI Preferred Stock will rank on a parity as
to dividends and assets with all other series according to the respective
dividend rates and amounts attributable upon voluntary or involuntary
liquidation, dissolution or winding up of NBI fixed for each series and without
preference or priority of any series over any other series. All shares of NBI
Preferred Stock will rank, with respect to dividends and liquidation rights,
senior to the NBI Common Stock. The ability of the Board of Directors to issue
NBI Preferred Stock, while providing flexibility in connection with possible
acquisitions and other corporate purposes, could, among other things, adversely
affect the voting power of holders of NBI Common Stock, and, under certain
circumstances, may discourage an attempt by others to gain control of NBI.

Change in Control Provisions

     The following provisions of NBI's Articles could have the effect of
delaying, deterring or preventing a change in control of NBI.

     Article 6 of NBI's Articles requires the approval of the holders of at
least 80% of each class of NBI's outstanding voting stock for certain mergers
and other business combinations involving NBI and beneficial owners of 5% or
more of NBI's outstanding capital stock entitled to vote for the election of
directors, unless (i) the proposed business combination has been approved by a
majority of the members of the Board of Directors who are not affiliated with
the beneficial owner and who were directors before the beneficial owner became
such beneficial owner, or (ii) certain conditions regarding the nature and
amount of consideration to be received in the proposed business combination by
holders of NBI's capital stock have been satisfied. The affirmative vote of the
holders of at least 80% of each class of NBI's outstanding voting stock is
required to amend Article 6 or to adopt any provision inconsistent with Article
6.

     Additionally, NBI's Articles (i) classify the Board into three classes, as
nearly equal in number as possible, each of which serves for three years, with
one class being elected each year; (ii) provide that directors may be removed
only for cause and only by the holders of two-thirds or more of each class of
NBI's outstanding voting stock; (iii) provide that any vacancy on the Board of
Directors or newly-created directorships may be filled by a majority of the
remaining directors then in office, even if less than a quorum; (iv) provide
that the number of directors may not be less than nine nor more than twenty-six,
such definite number within that limitation to be set by the Bylaws of NBI; (v)
provide that the power to amend or adopt the Bylaws is vested in the Board of
Directors to act by the vote of two-thirds of a quorum, including two-thirds of
the directors unaffiliated with certain 5% beneficial owners; (vi) increase to
80% of each class of NBI's outstanding voting stock, the vote required for
stockholders to adopt, alter, amend or repeal certain provisions of the Articles
or to adopt any provision inconsistent 

                                      117
<PAGE>
 
with certain provisions of the Articles; and (vii) increase to 80% of each class
of NBI's outstanding voting stock, the vote required for stockholders to adopt
new Bylaws, or to alter, amend or repeal Bylaws adopted by either the
stockholders or the Board of Directors of NBI.

     The Bylaws include provisions setting forth specific conditions under
which: (i) business may be transacted at an annual meeting of stockholders and
(ii) persons may be nominated for election as directors of NBI at an annual
meeting of stockholders.

     In addition to the foregoing, in certain instances the issuance of
authorized but unissued shares of NBI Common Stock or NBI Preferred Stock may
have an anti-takeover effect.

     See "CERTAIN DIFFERENCES IN THE RIGHTS OF BTC AND NBI STOCKHOLDERS."

State Anti-Takeover Statutes

     The Virginia Act includes two anti-takeover statutes, the Affiliated
Transactions Statute and the Control Share Acquisitions Statute, applicable to
NBI.

     The Affiliated Transactions Statute restricts certain transactions
("affiliated transactions") between a Virginia corporation having more than 300
stockholders of record and a beneficial owner of more than 10% of any class of
voting stock (an "interested stockholder"). An "affiliated transaction" is
defined in the Virginia Act as any of the following transactions with or
proposed by an interested stockholder: a merger; a share exchange; certain
dispositions of assets or guaranties of indebtedness other than in the ordinary
course of business; certain significant securities issuances; dissolution of the
corporation; or reclassification of the corporation's securities. Under the
statute, an affiliated transaction generally requires the approval of a majority
of disinterested directors and two-thirds of the voting shares of the
corporation other than shares owned by an interested stockholder during a three-
year period commencing as of the date the interested stockholder crosses the 10%
threshold. This special voting provision does not apply if a majority of
disinterested directors approved the acquisition of the more than 10% interest
in advance. After the expiration of the three-year moratorium, an interested
stockholder may engage in an affiliated transaction only if it is approved by a
majority of disinterested directors or by two-thirds of the outstanding shares
held by disinterested stockholders, or if the transaction complies with certain
fair price provisions. This special voting rule is in addition to, and not in
lieu of, other voting provisions contained in the Virginia Act and NBI's
Articles.

     The Control Share Acquisitions Statute provides that, with respect to
Virginia corporations having 300 or more stockholders of record, shares acquired
in a transaction that would cause the acquiring person's aggregate share
ownership to meet or exceed any of three thresholds (20%, 33-1/3% or 50%) have
no voting rights unless such rights are granted by a majority vote of the shares
not owned by the acquiring person or any officer or employee-director of the
corporation. The statute sets out a procedure whereby the acquiring person may
call a special stockholder's meeting for the purpose of considering whether
voting rights should be conferred. Acquisitions pursuant to a merger or share
exchange to which the corporation is a party and acquisitions pursuant to a
tender or exchange offer arising out of an agreement to which the corporation is
a party are exempt from the statute.

           CERTAIN DIFFERENCES IN RIGHTS OF BTC AND NBI STOCKHOLDERS

General

     Stockholders of BTC, whose rights are governed by BTC's Articles and Bylaws
and by the Virginia Act and the Virginia Banking Act will, upon consummation of
the Merger, become stockholders of NBI. The rights of such stockholders as
stockholders of NBI will then be governed by the Articles and Bylaws of NBI and
by the Virginia Act.

                                      118
<PAGE>
 
     Except as set forth below, there are no material differences between the
rights of a BTC stockholder under BTC's Articles and Bylaws and under the
Virginia Act and the rights of an NBI stockholder under the Articles of NBI and
under the Virginia Act, on the other hand. This summary does not purport to be a
complete discussion of, and is qualified in its entirety by reference to, the
governing law and the Articles and Bylaws of each corporation.

     See "CERTAIN REGULATORY CONSIDERATIONS" for a discussion of federal and
state regulatory requirements affecting the businesses of BTC and NBI.

Authorized Capital

     BTC

     BTC's Articles authorize the issuance of up to 6,000,000 shares of BTC
Common Stock, par value $1.00 per share, of which 1,888,209 shares were issued
and outstanding as of the Record Date.

     NBI

     NBI's authorized capital is set forth under "DESCRIPTION OF NBI CAPITAL
STOCK--Authorized Capital."

Preemptive Rights of Stockholders

     BTC

     BTC stockholders currently have preemptive rights. The BTC Charter
Amendment, if approved, would, among other things, eliminate preemptive rights
of BTC stockholders. See "THE MERGER--BTC Charter Amendment."

     NBI

     NBI stockholders have no preemptive rights.

Amendment of Charter or Bylaws

     BTC

     Under Virginia law, BTC's Articles may be amended if the amendment is
adopted by the Board of Directors and approved by a vote of the holders of more
than two-thirds of the votes entitled to be cast on the amendment by each voting
group entitled to vote thereon.

     BTC's Bylaws provide that all amendments made to the Bylaws shall be made
at a meeting of the Board of Directors by a vote of at least two-thirds of all
of the directors and after the proposed amendment has been submitted to the
Board of Directors at a meeting assembled at least one month before the final
amendment is adopted.

     NBI

     NBI's Articles generally may be amended if the amendment is adopted by the
Board of Directors and approved by a vote of the holders of more than two-thirds
of the votes entitled to be cast on the amendment by each voting group entitled
to vote thereon. NBI's Articles, however, require the affirmative vote of at
least 80% of NBI's voting stock to amend or repeal, or to adopt any provision
inconsistent with, certain provisions of its Articles. See "DESCRIPTION OF NBI
CAPITAL STOCK--Other Provisions."

                                      119
<PAGE>
 
     NBI's Articles generally provide that the Board of Directors may, by a two-
thirds vote of a quorum, amend its Bylaws; provided, however, that, if there is
a stockholder (or any affiliate or associate of such stockholder) who, after May
11, 1993, acquires direct or indirect beneficial ownership of 5% or more of
NBI's capital stock entitled to vote in the election of directors (an
"Interested Stockholder"), such two-thirds vote shall include a two-thirds of
directors ("Continuing Directors") (i) none of whom is an Interested Stockholder
or an affiliate or associate of an Interested Stockholder, and (ii) each of whom
was a member of the NBI Board of Directors immediately prior to the time that
the Interested Stockholder became an Interested Stockholder. Under the NBI
Articles, stockholders may adopt new Bylaws or amend Bylaws adopted by the
stockholders or the Board of Directors by the affirmative vote of the holders of
not less than 80% of each class of the voting stock of NBI and may, by a similar
vote, prohibit the Board of Directors from amending any Bylaws adopted by the
stockholders. The affirmative vote of the holders of not less than 80% of each
class of voting stock is required to amend the provisions of NBI's Articles
establishing the foregoing rights.

     Effective as of the Merger Effective Date, NBI has agreed to cause its
Bylaws to be amended as follows: (i) the number of NBI directors shall be set at
nine (see discussion under "THE MERGER--Interests of Certain Persons"); (ii) the
affirmative vote of six out of nine NBI directors shall be required to approve
any of the following actions: (a) membership on the Board of Directors of BTC
(provided, however, that a director of BTC may be removed by action of NBI as
sole stockholder of BTC by the vote of a simple majority of NBI directors in the
event that such director commits a violation of law applicable to his duties as
a director of BTC which has a material adverse effect on BTC or engages in any
conduct in connection with his duties as a director for which he would not be
entitled to indemnification under the Articles of Incorporation of BTC), (b)
amendments to the Articles of Incorporation or Bylaws of BTC, (c) the merger,
consolidation or sale of all or substantially all of the assets of BTC, and (d)
a recommendation to the shareholders of NBI to merge, consolidate or sell all or
substantially all of the assets of NBI, where such recommendation is required by
law; (iii) to change the provisions requiring that NBI directors also be NBB
directors to permit directors of BTC to serve on the NBI Board as well; and (iv)
the Executive Committee shall not authorize or approve any action on behalf of
NBI described in (ii) above. NBI has agreed that these Bylaw amendments shall
not be amended or rescinded by action of its Board of Directors without the
affirmative vote of at least six directors until January 1, 2001, on and after
which time such Bylaw amendments may be amended or rescinded by a simple
majority vote of its Board of Directors as provided in the Bylaws of NBI. See
"THE MERGER--Management and Operations of NBI and BTC after the Merger."

Size and Classification of Board of Directors

     BTC

     BTC's Articles and Bylaws provide that the number of directors shall not be
less than five and shall be fixed by the Bylaws of BTC. The current number of
BTC directors is fixed at thirteen.

     NBI

     NBI's Articles provide for a Board of Directors consisting of not less than
nine nor more than twenty-six members, with the number to be fixed in NBI's
Bylaws. The Bylaws currently provide that the number of directors shall be ten.
There currently are nine members and one vacancy on the NBI Board of Directors.
No increase in the number of directors may shorten the term of any director then
in office. The NBI Board of Directors is divided into three classes, each as
nearly equal in number as possible, with one class being elected annually.

     Effective as of the Merger Effective Date, NBI will cause its Bylaws to be
amended to set the number of directors at nine and shall obtain the resignations
of four directors currently serving on the NBI Board of Directors. The four NBI
Board Vacancies created by such resignations will be filled by BTC Board
Representatives. See "THE MERGER--Management and Operations of NBI and BTC after
the Merger" and "--Interests of Certain Persons."

Removal of Directors

     BTC

     Directors of BTC may be removed, with or without cause, by the stockholders
by a majority of the votes entitled to be cast at a stockholders' meeting called
for such purpose at which a quorum is present. BTC's Bylaws provide that any
director also may be removed at any time by a majority vote of the Board of
Directors of BTC.

     NBI

     Directors of NBI may be removed only for cause and only by a vote of the
holders of at least two-thirds of each class of the voting stock of NBI then
outstanding at a meeting called for that purpose.

Director Exculpation

     BTC

     BTC's Articles provide for the limitation or elimination of personal
liability of each BTC director and officer to the fullest extent permitted by
the Virginia Act, as the same may be in effect from time to time. In accordance
with the Virginia Act, that limitation of liability does not apply if the
director or officer engaged in willful misconduct or a knowing violation of
criminal law or any federal or state securities law. The BTC Charter Amendment
would delete this provision from the Articles of BTC. Accordingly, under the
Virginia Act, the liability of a director or officer of BTC, as a director or
officer of BTC would be the greater of $100,000 or the amount of compensation
received by the officer or director in the twelve months preceding the act or
omission giving rise to the liability. See "THE MERGER--BTC Charter Amendment."

     NBI

     NBI's Articles provide for the limitation or elimination of personal
liability of directors or officers of NBI to the fullest extent permitted by the
Virginia Act, as the same may be in effect from time to time.

Indemnification

     BTC

     BTC's Articles provide for indemnification or reimbursement of directors,
officers and employees of BTC to the fullest extent permitted by the Virginia
Act, as it may be amended and as set forth in the Articles. The right to
indemnification under BTC's Articles does not extend to: (i) indemnification or
reimbursement for amounts actually paid to BTC pursuant to a settlement
agreement, or in satisfaction of a judgment arising out of litigation that was
brought by or in the right of BTC; and (ii) indemnification of any amount or
expense where the director, officer or employee has been finally adjudged to be
liable by reason of gross negligence or willful misconduct in the performance of
his duties. The BTC Charter Amendment would amend these indemnification
provisions, as described under "THE MERGER--BTC Charter Amendment."

     NBI

     NBI's Articles require indemnification of any director or officer against
liability incurred in connection with any proceeding to which that person is
made a party by virtue of such person's service as a director or officer of NBI,
or service as a director, officer, employee or agent of another entity at the
request of NBI, except in the case of willful misconduct or a knowing violation
of the criminal law. In certain circumstances, NBI's Articles also require NBI
to reimburse a director or officer made a party to a proceeding in advance of
the final disposition of the proceeding. NBI's Articles permit indemnification
of any other person who is or was a party to a proceeding by reason of the fact
that such person is or was an employee or agent of NBI, or is or was serving
another entity 

                                      121
<PAGE>
 
at the request of NBI, to the same extent as if such person was a director or
officer. Indemnification and advancement of and reimbursement for expenses is
subject to a determination that indemnification is appropriate by a majority of
a quorum consisting of directors not at the time parties to the proceeding. In
the event that such a quorum cannot be obtained or there has been a change in
the composition of the majority of the Board of Directors after the date of the
alleged act with respect to which indemnification is claimed, such determination
shall be made by special legal counsel.

Director Nominations and Stockholder Proposals

     BTC

     Neither BTC's Articles nor Bylaws establish any procedures that may be
followed for stockholders to nominate individuals for election to the Board of
Directors or to submit a proposal to a vote of the stockholders of BTC.

     NBI

     NBI's Bylaws establish procedures that must be followed for stockholders to
nominate persons for election to NBI's Board of Directors or to submit a
proposal to a vote of stockholders of NBI at an annual meeting of stockholders.
Such nominations or proposals must be made by delivering written notice to the
President of NBI not less than sixty nor more than ninety days prior to the
annual meeting; provided, however, that if less than seventy days' notice of the
date of the meeting is given, such written notice by the stockholder must be
delivered not later than the tenth day after the day on which such notice of the
date of the meeting was given. Notice will be deemed to have been given more
than seventy days prior to the meeting if a meeting is called on the second
Tuesday of April (or if such date falls on a legal holiday, the next business
day) regardless as to when public disclosure is made. The nomination or
stockholder proposal notice must set forth (i) a brief description of the
proposal and the reasons for its submission; (ii) the name and address of the
stockholder, as they appear on NBI's books; (iii) the classes and number of
shares of NBI owned by the stockholder; and (iv) any material interest of the
stockholder in such proposal other than such holder's interest as a stockholder
of NBI. The Chairman of the meeting will, if the facts warrant, determine that a
nomination or stockholder proposal is not made in accordance with the provision
prescribed by the Bylaws and the defective nomination or stockholder proposal
will be disregarded.

Required Stockholder Vote for Certain Actions

     BTC

     The Virginia Act generally provides that mergers, share exchanges and a
corporation's sale of all or substantially all of its assets other than in the
usual or regular course of business must be adopted by the Board of Directors
and approved by more than two-thirds of all votes entitled to be cast by each
voting group entitled to vote on the plan of merger, share exchange or sale of
assets, unless the corporation's board of directors requires a greater vote or
the corporation's articles of incorporation provide for a greater or lesser vote
(which BTC's Articles and Bylaws do not). With respect to a merger, no vote of
the stockholders of the surviving corporation is required if: (i) the
corporation's articles of incorporation will not differ significantly after the
merger; (ii) the corporation's stockholders will hold the same number of shares,
with identical designations, preferences, limitations and relative rights, after
the merger; (iii) the number of voting shares outstanding immediately after the
merger (including shares issuable upon conversion of securities or exercise of
rights or warrants issued in the merger) will not exceed by more than 20% the
total number of voting shares of the surviving corporation outstanding before
the merger; and (iv) the number of shares entitling their holders to unlimited
participation in distributions outstanding after the merger, plus the number of
participating shares issuable as a result of such merger (including shares
issuable upon conversion of securities or exercise of rights or warrants issued
in the merger), will not exceed by more than 20% the total number of such shares
outstanding before the merger.

                                      122
<PAGE>
 
     NBI

     NBI's Articles require the approval of holders of at least 80% of each
class of NBI outstanding voting stock for certain mergers, share exchanges,
sales of assets and other business combinations involving NBI and beneficial
owners of 5% or more of NBI's outstanding capital stock entitled to vote for the
election of directors (before or after the transaction) unless (i) the
transaction has been approved by a majority of the members of the Board of
Directors who are not affiliated with the beneficial owner and who were
directors before the beneficial owner became such beneficial owner, or (ii)
certain conditions regarding the nature and amount of consideration to be
received in the transaction by holders of NBI capital stock have been satisfied.
If required under this provision, such 80% approval is required, notwithstanding
the fact that no vote is required or that a lesser percentage is specified by
the Virginia Act or in any agreement to which NBI is a party. The affirmative
vote of the holders of at least 80% of each class of NBI's outstanding voting
stock is required to amend or to adopt any provision inconsistent with these
requirements.

Voluntary Dissolution

     BTC

     Under the Virginia Act, a corporation's board of directors may propose
dissolution for submission to the stockholders. Unless the board of directors
requires a greater vote, dissolution to be authorized must be approved by the
holders of more than two-thirds of all votes entitled to be cast on the proposal
to dissolve. The board of directors may condition its submission of a proposal
for dissolution on any basis. Subject to federal and state bank regulatory
requirements, the provisions of the Affiliated Transactions Statute will apply
if the dissolution of BTC is proposed by or on behalf of an Interested
Stockholder.

     NBI

     NBI may be dissolved if its Board of Directors proposes dissolution, and
more than two-thirds of the shares of NBI entitled to vote thereon approve;
provided, however, that under NBI's Articles, the approval of the holders of at
least 80% of each class of NBI's outstanding voting stock is required for the
adoption of a plan or proposal for liquidation or dissolution if the same is not
approved by a majority of the directors, including a majority of the Continuing
Directors. The requirements of the Affiliated Transactions Statute will apply if
dissolution of NBI is proposed by or on behalf of an Interested Stockholder.

     See "DESCRIPTION OF NBI CAPITAL STOCK--State Anti-Takeover Statutes" above.

                          RESALE OF NBI COMMON SHARES


     The NBI Common Shares have been registered under the Securities Act,
thereby allowing such shares to be traded freely and without restriction by
those holders of BTC Common Stock who receive such shares following consummation
of the Merger and who are not deemed to be "affiliates" (as defined under the
Securities Act, but generally including directors, certain executive officers
and certain large stockholders) of BTC or NBI. The Merger Agreement provides
that each holder of BTC Common Stock who is deemed by BTC to be an affiliate of
it will enter into an agreement with NBI not later than thirty days prior to the
Merger Effective Date providing, among other things, that such affiliate will
not transfer any NBI Common Shares received by such holder in the Merger except
in compliance with the Securities Act and will not sell or otherwise transfer
such shares until financial results of NBI and its subsidiaries (including BTC)
for at least thirty days of combined operations are published. This
Prospectus/Proxy Statement does not cover any resales of NBI Common Shares.

                              ADDITIONAL MATTERS

     From time to time NBB has entered into transactions with BTC in the
ordinary course of business, including, without limitation, the sale of loan
participations in commercial and mortgage loans.

                          Independent Auditors' Report



     The Board of Directors and Stockholders
     National Bankshares, Inc.:

          We have audited the accompanying consolidated balance sheets of
     National Bankshares, Inc. and subsidiary as of December 31, 1994 and 1993,
     and the related consolidated statements of income, changes in stockholders'
     equity, and cash flows for each of the years in the three-year period ended
     December 31, 1994.  These consolidated financial statements are the
     responsibility of Bankshares' management.  Our responsibility is to express
     an opinion on these consolidated financial statements based on our audits.

          We conducted our audits in accordance with generally accepted auditing
     standards.  Those standards require that we plan and perform the audit to
     obtain reasonable assurance about whether the financial statements are free
     of material misstatement.  An audit includes examining, on a test basis,
     evidence supporting the amounts and disclosures in the financial
     statements.  An audit also includes assessing the accounting principles
     used and significant estimates made by management, as well as evaluating
     the overall financial statement presentation.  We believe that our audits
     provide a reasonable basis for our opinion.

          In our opinion, the consolidated financial statements referred to
     above present fairly, in all material respects, the  financial position of
     National Bankshares, Inc. and subsidiary as of December 31, 1994 and 1993,
     and the results of their operations and their cash flows for each of the
     years in the three-year period ended December 31, 1994 in conformity with
     generally accepted accounting principles.

          As discussed in notes 1(C) and 3 to the consolidated financial
     statements, Bankshares adopted the provisions of Statement of Financial
     Accounting Standards No. 115, "Accounting for Certain Investments in Debt
     and Equity Securities," as of January 1, 1994.  As discussed in notes 1(J)
     and 11 to the consolidated financial statements, Bankshares adopted the
     provisions of Statement of Financial Accounting Standards No. 109,
     "Accounting for Income Taxes," as of January 1, 1993.

Note 1              The accounting and reporting policies of National 
Summary of    Bankshares, Inc. and its wholly-owned subsidiary, The National
Significant   Bank of Blacksburg (NBB), conform to generally accepted 
Accounting    accounting principles and general practices within the banking 
Policies      industry.  In preparing the consolidated financial statements, 
              management is required to make certain estimates, assumptions
              and loan evaluations that affect its consolidated financial 
              statements for the period.  Actual results could vary 
              significantly from those estimates.
 
                    Changing economic conditions, adverse economic prospects for
              NBB's borrowers, as well as regulatory agency action as a result
              of an examination, could cause NBB to recognize additions to the
              allowance for loan losses and may also affect the valuation of
              real estate acquired in connection with foreclosures or in
              satisfaction of loans.
 
                    The following is a summary of the more significant
              accounting policies.
 
              (A)   Consolidation
 
                    The consolidated financial statements include the accounts
              of National Bankshares, Inc. and its wholly-owned subsidiary
              (Bankshares). All significant intercompany balances and
              transactions have been eliminated.
 
              (B)   Cash and Cash Equivalents
 
                    For purposes of reporting cash flows, cash and cash
              equivalents include cash on hand and due from banks.
 
              (C)   Securities
 
                    Effective January 1, 1994, Bankshares adopted the provisions
              of Statement of Financial Accounting Standards (SFAS) No. 115,
              "Accounting for Certain Investments in Debt and Equity
              Securities," and accordingly, has recorded the effect of this
              adoption in the accompanying consolidated financial statements for
              the year ended December 31, 1994. SFAS No. 115 established new
              standards of accounting and reporting for investments in equity
              securities that have readily-determinable fair values and for all
              investments in debt securities. SFAS No. 115 requires those
              investments to be classified in three categories: (1) debt
              securities that the organization has the positive intent and
              ability to hold to maturity are classified as "held to maturity
              securities" and reported at amortized cost; (2) debt and equity
              securities that are bought and held principally for the purpose of
              selling them in the near term are classified as "trading
              securities" and reported at fair value, with unrealized gains and
              losses included in net income; and (3) debt and equity securities
              not classified as either held to maturity securities or trading
              securities are classified as "available for sale securities" and
              reported at fair value, with unrealized gains and losses excluded
              from net income and reported, net of income taxes, in a separate
              component of stockholders' equity.
 
                    Securities available for sale are reported at fair value,
              with unrealized gains and losses excluded from net income and
              reported, net of income taxes, in a separate component of


                                      F-7

                           National Bankshares, Inc.
                  Notes to Consolidated Financial Statements

              stockholders' equity. Securities held to maturity are stated at
              cost, adjusted for amortization of premiums and accretion of
              discounts on a basis which approximates the level yield method.


                    Bankshares does not maintain trading securities. Gains and
              losses on securities are accounted for on the completed
              transaction basis by the specific identification method.

                    A decline in the fair value of any available for sale or
              held to maturity security below cost that is deemed other than
              temporary is charged to income resulting in the establishment of a
              new cost basis for the security.

              (D)   Loans

                    Loans are stated at the amount of funds disbursed plus the
              applicable amount, if any, of unearned interest and other charges
              less payments received. Income on installment loans is recognized
              on methods which approximate the level yield method. Interest on
              all other loans is accrued based on the balance outstanding times
              the applicable interest rate.

                    Interest is recognized on the cash basis for all loans
              carried in nonaccrual status. Loans generally are placed in
              nonaccrual status when the collection of principal or interest is
              90 days or more past due, unless the obligation is both well-
              secured and in the process of collection.

                    Loan origination and commitment fees and certain direct
              costs are being deferred, and the net amount amortized as an
              adjustment of the related loan's yield. These amounts are being
              amortized over the contractual life of the related loans.

                    Mortgage loans held for sale are carried at the lower of
              cost or fair value.

              (E)   Allowance for Loan Losses

                    The allowance for loan losses is a valuation allowance
              consisting of the cumulative effect of the provision for loan
              losses, plus any amounts recovered on loans previously charged
              off, minus loans charged off. The provision for loan losses
              charged to expense is the amount necessary in management's
              judgement to maintain the allowance for loan losses at a level it
              believes adequate to absorb losses in the collection of its loans.

              (F)   Bank Premises and Equipment

                    Bank premises and equipment are stated at cost, net of
              accumulated depreciation. Depreciation is charged to expense over
              the estimated useful lives of the assets on the straight-line
              basis. Costs of maintenance and repairs are charged to expense as
              incurred and improvements are capitalized.

              (G)   Other Real Estate Owned

                    Other real estate, acquired through foreclosure or deed in
              lieu of foreclosure, is carried at the lower of the recorded
              investment or its fair value, less estimated costs to sell (net
              realizable value). When the property is acquired, any excess of
              the loan balance over net realizable value is charged to the
              allowance for loan losses. Increases or decreases in the net
              realizable value of such 

                                      F-8
<PAGE>
 
                           National Bankshares, Inc.
                  Notes to Consolidated Financial Statements


              properties are credited or charged to income by adjusting the
              valuation allowance for other real estate owned. Net costs of
              maintaining or operating foreclosed properties are expensed as
              incurred.

              (H)   Intangible Assets

                    Included in other assets are deposit intangibles of $872 and
              $68 at December 31, 1994 and 1993, respectively, and goodwill of
              $427 at December 31, 1994. Deposit intangibles are being amortized
              on a straight-line basis over either a seven-year or ten-year
              period and goodwill is being amortized on a straight-line basis
              over a fifteen-year period. (See note 20).

              (I)   Pension Plan

                    Bankshares has a defined benefit pension plan which covers
              substantially all full-time officers and employees. The benefits
              are based upon length of service and a percentage of the
              employee's compensation during the final years of employment.
              Pension costs are computed based upon the provisions of SFAS No.
              87. NBB contributes to the pension plan amounts deductible for
              federal income tax purposes.

              (J)   Income Taxes

                    Effective January 1, 1993, Bankshares adopted the provisions
              of SFAS No. 109, "Accounting for Income Taxes," and has reported
              the cumulative effect of that change in the method of accounting
              for income taxes in the 1993 consolidated statement of income.
              SFAS No. 109 requires a change from the deferred method of
              accounting for income taxes of Accounting Principles Board (APB)
              Opinion 11 to the asset and liability method of accounting for
              income taxes. Under the asset and liability method of SFAS No.
              109, deferred tax assets and liabilities are recognized for the
              future tax consequences attributable to differences between the
              financial statement carrying amounts of existing assets and
              liabilities and their respective tax bases and operating loss and
              tax credit carryforwards. Deferred tax assets and liabilities are
              measured using enacted tax rates expected to apply to taxable
              income in the years in which those temporary differences are
              expected to be recovered or settled. Under SFAS No. 109, the
              effect on deferred tax assets and liabilities of a change in tax
              rates is recognized in income in the period that includes the
              enactment date.

                    Pursuant to the deferred method under APB Opinion 11, which
              was applied by Bankshares prior to January 1, 1993, deferred
              income taxes were recognized for income and expense items that
              were reported in different years for financial reporting purposes
              and income tax purposes using the tax rate applicable in the year
              of the calculation. Under the deferred method, deferred taxes were
              not adjusted for subsequent changes in tax rates.

              (K)   Trust Assets and Income

                    Assets (other than cash deposits) held by the Trust
              Department in a fiduciary or agency capacity for customers are not
              included in the consolidated financial statements since such items
              are not assets of NBB. Trust income is recognized on the accrual
              basis.

              (L)   Net Income Per Share

                    Net income per share is based upon the weighted average
              number of common shares outstanding (1,710,310 shares in 1994,
              1,707,764 shares in 1993 and 1,701,372 shares in 1992).

              (M)   Off-Balance Sheet Financial Instruments

                    In the ordinary course of business, NBB has entered into 
              off-balance sheet financial instruments consisting of commitments
              to extend credit and standby letters of credit. Such financial
              instruments are recorded in the financial statements when they
              become payable.

              (N)   Fair Value of Financial Instruments

                    The following methods and assumptions were used to estimate
              the fair value of each class of financial instrument for which it
              is practicable to estimate that value:

                    (1)   Cash and Due from Banks

                          The carrying amount is a reasonable estimate of fair
                          value.

                    (2)  Federal Funds Sold

                         The carrying amount is a reasonable estimate of fair
                         value.

                    (3)  Securities

                         The fair value of securities, except certain state and
                    municipal securities, is estimated based on bid prices
                    published in financial newspapers or bid quotations received
                    from securities dealers. The fair value of certain state and
                    municipal securities is not readily available through market
                    sources other than dealer quotations, so fair value
                    estimates are based on quoted market prices of similar
                    instruments, adjusted for differences between the quoted
                    instruments and the instruments being valued.

                    (4)  Loans

                         Fair values are estimated for portfolios of loans with
                    similar financial characteristics. Loans are segregated by
                    type such as mortgage loans held for sale, commercial, real
                    estate - commercial, real estate - construction, real 
                    estate -mortgage, credit card and other consumer loans. Each
                    loan category is further segmented into fixed and adjustable
                    rate interest terms and by performing and nonperforming
                    categories.

                         The fair value of performing loans is calculated by
                    discounting scheduled cash flows through the estimated
                    maturity using estimated market discount rates that reflect
                    the credit and interest rate risk inherent in the loan, as
                    well as estimates for operating expenses and prepayments.
                    The estimate of maturity is based on Bankshares' historical
                    experience with repayments for each loan classification,
                    modified, as required, by an estimate of the effect of
                    current economic and lending conditions.

                         Fair value for significant nonperforming loans is based
                    on estimated cash flows which are discounted using a rate
                    commensurate with the risk associated with the estimated
                    cash flows. Assumptions regarding credit risk, cash flows
                    and discount rates are judgmentally determined using
                    available market information and specific borrower
                    information.

                    (5) Deposits

                        The fair value of demand and savings deposits is the
                    amount payable on demand. The fair value of fixed maturity
                    time deposits and certificates of deposit is estimated using
                    the rates currently offered for deposits with similar
                    remaining maturities.

                    (6) Commitments to Extend Credit and Standby Letters of
                        Credit

                        The only amounts recorded for commitments to extend
                    credit, standby letters of credit and financial guarantees
                    written are the deferred fees arising from these

Note 3              As discussed in note 1(C), effective January 1, 1994, 
Securities       Bankshares adopted the provisions of SFAS No. 115, 
Available        "Accounting for Certain Investments in Debt and Equity  
for Sale         Securities." Upon adoption of SFAS No. 115, certain investment
                 securities totaling $17,451 were reclassified from securities
                 held to maturity to securities available for sale. The
                 cumulative effect of this change in accounting at January 1,
                 1994 was to increase securities available for sale by $414,
                 decrease the net deferred tax asset by $141 and increase
                 stockholders' equity by $273.
 
                    The amortized costs, gross unrealized gains, gross
                 unrealized losses and fair values for securities available for
                 sale by major security type as of December 31, 1994 were as

Note 10             NBB has a Retirement Accumulation Plan qualifying under IRS
Employee Benefit Code Section 401(k). Eligible participants in the plan can
Plans            contribute up to 10 percent of their total annual compensation
                 to the plan. Employee contributions are matched by NBB based on
                 a percentage of an employee's total annual compensation
                 contributed to the plan. For the years ended December 31, 1994,
                 1993 and 1992, NBB contributed $76, $69 and $54, respectively,
                 to the plan.
 
                    National Bankshares, Inc. has a nonleveraged Employee Stock
                 Ownership Plan (ESOP) which enables employees with one year of
                 service who have attained the age of 21 prior to the plan's
                 January 1 and July 1 enrollment dates to own common stock in
                 Bankshares. Contributions to the ESOP are determined annually
                 by the Board of Directors. Contribution expense amounted to
                 $145, $134 and $115 for the years ended December 31, 1994, 1993
                 and 1992, respectively. Dividends on ESOP shares are charged to
                 undivided profits. As of December 31, 1994, the number of
                 allocated shares held by the ESOP was 43,840 and the number of
                 unallocated shares was 7,266. All shares held by the ESOP are
                 treated as outstanding in computing Bankshares' net income per
                 share. The ESOP has the right of first refusal for any shares
                 distributed to a participant in the event the participant
                 elects to sell the shares. Upon reaching age 55 with ten years
                 of plan participation, a vested participant has the right to
                 diversify 50 percent of his or her allocated ESOP shares and
                 the ESOP would be obligated to purchase those shares.
 
                    NBB also has a noncontributory defined benefit pension plan
                 which covers all full-time officers and employees with six
                 months of service who have attained the age of 20 years and six
                 months prior to the plan's January 1 enrollment date. The
                 pension plan's benefit formulas generally base payments to
                 retired employees upon their length of service and a percentage
                 of qualifying compensation during their final years of
                 employment. The pension plan's assets are invested principally
                 in U.S. Government agency obligations and mutual funds.
 
                    The plan's funded status at December 31, 1994 and 1993 is as
                 follows:

                    The weighted average discount rate was 8.5% in 1994, 7% in
                 1993 and 8.25% in 1992. The rate of increase in future
                 compensation levels was 5% for 1994, 1993 and 1992. These rates
                 were used in determining the actuarial present value of the
                 projected benefit obligation. The expected long-term rate of
                 return on assets was 9% in 1994, 1993 and 1992.

Note 11             As discussed in note 1(J), Bankshares adopted SFAS No. 109
Income Taxes     as of January 1, 1993. The cumulative effect of this change in
                 accounting for income taxes of $28 is reported separately in
                 the 1993 consolidated statement of income. Prior years'
                 consolidated financial statements have not been restated to
                 apply the provisions of SFAS No. 109.

                    Total income taxes were allocated as follows:

                    Bankshares has determined that a valuation allowance for the
                 gross deferred tax assets is not necessary at December 31, 1994
                 and 1993 due to the fact that the realization of the entire
                 gross deferred tax assets can be supported by the amount of
                 taxes paid during the carryback period available under current
                 tax laws.

                  Notes to Consolidated Financial Statements

                    For the year ended December 31, 1992, deferred income tax
                 benefits attributable to income before income tax expense and
                 cumulative effect of change in accounting principle results
                 from timing differences in the recognition of income and
                 expense for income tax and financial reporting purposes. The
                 sources of timing differences resulting in deferred income
                 taxes and the tax effect of each were as follows:

Note 17             NBB is a party to financial instruments with off-balance 
Financial         sheet risk in the normal course of business to meet the 
Instruments with  financing needs of its customers. These financial instruments 
Off-Balance       include commitments to extend credit and standby letters of 
Sheet Risk        credit. Those instruments involve, to varying degrees, 
                  elements of credit risk in excess of the amount recognized in 
                  the consolidated balance sheets.  The contract amounts of 
                  those instruments reflect the extent of involvement NBB has in
                  particular classes of financial instruments.
 
                    NBB's exposure to credit loss, in the event of
                  nonperformance by the other party to the financial instrument
                  for commitments to extend credit and standby letters of
                  credit, is represented by the contractual amount of those
                  instruments. NBB uses the same credit policies in making
                  commitments and conditional obligations as it does for 
                  on-balance sheet instruments.
 
                    NBB may require collateral or other security to support the
                  following financial instruments with credit risk:

</TABLE> 
                    Commitments to extend credit are agreements to lend to a
                  customer as long as there is no violation of any condition
                  established in the contract. Commitments to extend credit are
                  predominantly at variable rates with the exception of
                  construction loans which have a fixed rate, but a duration of
                  generally less than one year. Commitments generally have fixed
                  expiration dates or other termination clauses and may require
                  payment of a fee. Since many of the commitments

                  Notes to Consolidated Financial Statements

                 are expected to expire without being drawn upon, the total
                 commitment amounts do not necessarily represent future cash
                 requirements. NBB evaluates each customer's creditworthiness on
                 a case-by-case basis. The amount of collateral obtained, if
                 required by NBB upon extension of credit, is based on
                 management's credit evaluation of the customer. Collateral held
                 varies but may include accounts receivable, inventory,
                 property, plant and equipment and income-producing commercial
                 properties.
 
                    Standby letters of credit are conditional commitments issued
                 by NBB to guarantee the performance of a customer to a third
                 party. The credit risk involved in issuing letters of credit is
                 essentially the same as that involved in extending loans to
                 customers. Collateral held varies but may include accounts
                 receivable, inventory, property, plant and equipment and 
                 income-producing commercial properties.
 
                    NBB originates mortgage loans for sale to secondary market
                 investors subject to contractually specified and limited
                 recourse provisions. In 1994, NBB originated $15,084 and sold
                 $16,444 to investors, compared to $33,853 originated and
                 $33,003 sold in 1993. Every contract with each investor
                 contains certain recourse language. In general, NBB may be
                 required to repurchase a previously sold mortgage loan if there
                 is major noncompliance with defined loan origination or
                 documentation standards, including fraud, negligence or
                 material misstatement in the loan documents. Repurchase may
                 also be required if necessary governmental loan guarantees are
                 canceled or never issued, or if an investor is forced to buy
                 back a loan after it has been resold as a part of a loan pool.
                 In addition, NBB may have an obligation to repurchase a loan if
                 the mortgagor has defaulted early in the loan term. This
                 potential default period ranges from four to sixteen months
                 after sale of a loan to the investor. At December 31, 1994
                 loans with potential recourse approximated $29,060.

Note 18             NBB does a general banking business, serving the commercial,
Concentrations   agricultural and personal banking needs of its customers in its
of Credit Risk   trade territory, commonly referred to as the New River Valley,
                 which consists of Montgomery and Giles Counties, Virginia and 
                 portions of adjacent counties. Operating results are closely
                 correlated with the economic trends within this area which are,
                 in turn, influenced by the area's three largest employers,
                 Virginia Polytechnic Institute and State University, the
                 Radford Army Ammunition Plant (Hercules, Inc.) and 
                 Hoechst-Celanese. Other industries include a wide variety of
                 manufacturing and retail concerns. The ultimate collectibility
                 of the loan portfolios and the recovery of the carrying amounts
                 of repossessed property are susceptible to changes in the
                 market conditions of this area. Real estate construction loans
                 are concentrated within NBB's trade territory. The commercial
                 portfolio is diversified with no significant concentrations of
                 credit within a single industry. As of December 31, 1994 and
                 1993, approximately $24 million and $31 million, respectively,
                 of the commercial loan portfolio consisted of loans secured by
                 commercial real estate. Loans to individuals included
                 approximately $18 million and $13 million, respectively, of
                 loans secured by vehicles. These loans are generally
                 collateralized by the related property. As of December 31, 1994
                 and 1993, the real estate mortgage portfolio included
                 approximately $21 million of residential mortgage loans secured
                 by 1-4 family properties.
 
                    NBB has established operating policies relating to the
                 credit process and collateral in loan originations. Loans to
                 purchase real and personal property are generally
                 collateralized by the related property and with loan amounts
                 established based on certain percentage limitations of the
                 property's total stated or appraised value. Credit approval is
                 primarily a function of collateral and the evaluation of the
                 creditworthiness of the individual borrower or project based on
                 available financial information.

                    Fair value estimates are made at a specific point in time,
                 based on relevant market information and information about the
                 financial instrument. These estimates do not reflect any
                 premium or discount that could result from offering for sale at
                 one time Bankshares' entire holdings of a particular financial
                 instrument. Because no market exists for a significant portion
                 of Bankshares' financial instruments, fair value estimates are
                 based on judgements regarding future expected loss experience,
                 current economic conditions, risk characteristics of various
                 financial instruments and other factors. These estimates are
                 subjective in nature and involve uncertainties and matters of
                 significant judgement and therefore cannot be determined with
                 precision. Changes in assumptions could significantly affect
                 these estimates.
 
                    Fair value estimates are based on existing on-and 
                 off-balance sheet financial instruments without attempting to
                 estimate the value of anticipated future business and the value
                 of assets and liabilities that are not considered financial
                 instruments. Significant assets that are not considered
                 financial assets include deferred tax assets and bank premises
                 and equipment. In addition, the tax ramifications related to
                 the realization of the unrealized gains and losses can have a
                 significant effect on fair value estimates and have not been
                 considered in the estimates.
 
Note 20             On November 23, 1993, NBB entered into an agreement to 
Purchase         purchase the deposits and certain fixed assets of the Pembroke
Transaction      Office of First Union National Bank of Virginia. Settlement 
                 of this purchase agreement occurred on April 16, 1994, with the
                 assumption of $14,514 in total deposits and $33 in accrued
                 interest payable. In conjunction with this purchase, deposit
                 intangibles of $908 are being amortized on a straight-line
                 basis over a ten-year period and goodwill of $447 is being
                 amortized on a straight-line basis over a fifteen-year period.
 
Note 21             The Financial Accounting Standards Board (FASB) has issued 
Future           SFAS No. 114, "Accounting by Creditors for Impairment of a 
Accounting       Loan."  SFAS No. 114 requires that certain loans which have 
Considerations   been determined to be impaired be measured based on the present
                 value of expected future cash flows discounted at the loan's
                 effective interest rate or, as a practical expedient, at the
                 loan's observable market price or the fair value of the
                 collateral if the loan is collateral dependent. SFAS No. 114
                 also requires creditors to evaluate the collectibility of both
                 contractual interest and contractual principal of all
                 receivables when assessing the need for a loss accrual.

                  Notes to Consolidated Financial Statements

                    In October 1994, the FASB issued SFAS No. 118, "Accounting
                 by Creditors for Impairment of a Loan - Income Recognition and
                 Disclosures." SFAS No. 118 amends SFAS No. 114 to allow a
                 creditor to use existing methods for recognizing interest
                 income on an impaired loan. To accomplish that, SFAS No. 118
                 eliminates the provisions in SFAS No. 114 that described how a
                 creditor should report income on an impaired loan. SFAS No. 118
                 does not change the provisions in SFAS No. 114 that required a
                 creditor to measure impairment based on the present value of
                 expected future cash flows discounted at the loan's effective
                 interest rate, or as a practical expedient, at the observable
                 market price of the loan or the fair value of the collateral if
                 the loan is collateral dependent. SFAS No. 118 amends the
                 disclosure requirements in SFAS No. 114 to require information
                 about the recorded investment in certain impaired loans and
                 about how a creditor recognizes interest income related to
                 those impaired loans.
 
                    SFAS No. 118 is effective concurrent with the effective date
                 of SFAS No. 114. The mandatory adoption date of SFAS No. 114
                 and SFAS No. 118 by Bankshares is January 1, 1995 and,
                 consistent with the requirements of SFAS No. 114, they will be
                 adopted by Bankshares on a prospective basis. Bankshares did
                 not elect early adoption of SFAS No. 114 and SFAS No. 118, and
                 anticipates that the effects of adoption will not materially
                 impact its consolidated financial statements.

 4.  MORTGAGE BANKING ACTIVITIES
     ---------------------------

     NBB originates mortgage loans for sale to secondary market investors
     subject to contractually specified and limited recourse provisions.  For
     the nine months ended September 30, 1995, NBB originated $11,475 and sold
     $10,549 in mortgage loans to investors.  Every contract with each investor
     contains certain recourse language.  In general, NBB may be required to
     repurchase a previously sold mortgage loan if there is major noncompliance
     with defined loan origination or documentation standards, including fraud,
     negligence or material misstatement in the loan documents.  Repurchase may
     also be required if necessary governmental loan guarantees are canceled or
     never issued, or if an investor is forced to buy back a loan after it has
     been resold as a part of a loan pool.  In addition, NBB may have an
     obligation to repurchase a loan if the mortgagor has defaulted early in the
     loan term.  This potential default period approximates twelve months after
     sale of a loan to the investor.  At September 30, 1995, loans with
     potential recourse approximated $13,258.

 6.  IMPAIRED LOANS AND NONPERFORMING ASSETS
     ---------------------------------------

     Effective January 1, 1995, Bankshares adopted the provisions of Statement
     of Financial Accounting Standards (SFAS) No. 114, "Accounting by Creditors
     for Impairment of a Loan," as amended by SFAS No. 118, "Accounting by
     Creditors for Impairment of a Loan - Income Recognition and Disclosures."
     SFAS No. 114 requires that certain loans which have been determined to be
     impaired be measured based on the present value of expected future cash
     flows discounted at the loan's effective interest rate or, as a practical
     expedient, at the loan's observable market price or the fair value of the
     collateral if the loan is collateral dependent.  SFAS No. 114 also required
     creditors to evaluate the collectibility of both contractual interest and
     contractual principal of all receivables when assessing the need for a loss
     accrual.  In addition, SFAS No. 114 eliminates the requirement that a
     creditor account for certain loans as foreclosed assets prior to the time
     the creditor has taken possession of the underlying collateral, resulting
     in the reclassification of in-substance foreclosures from foreclosed
     properties to loans.

     SFAS No. 118 amends SFAS No. 114 to allow a creditor to use existing
     methods for recognizing interest income on an impaired loan.  To accomplish
     that, SFAS No. 118 eliminates the provisions in SFAS No. 114 that described
     how a creditor should report income on an impaired loan.  SFAS No. 118 does
     not change the provisions in SFAS No. 114 that required a creditor to
     measure impairment based on the present value of expected future cash flows
     discounted at the loan's effective interest rate, or as a practical
     expedient, at the observable market price of the loan or the fair value of
     the collateral if the loan is collateral dependent.  SFAS No. 118 amends
     the disclosure requirements in SFAS No. 114 to require information about
     the recorded investment in certain impaired loans and about how a creditor
     recognizes interest income related to those impaired loans.

     SFAS No. 114 does not apply to large groups of smaller balance homogeneous
     loans that are collectively evaluated for impairment.  For Bankshares,
     loans collectively reviewed for impairment include all consumer loans,
     single family loans and performing multi-family and nonresidential real
     estate loans, excluding loans which have entered into the "workout
     process."

     Bankshares considers a loan to be impaired when, based upon current
     information and events, it believes it is probable that Bankshares will be
     unable to collect all amounts due according to the contractual terms of the
     loan agreement.  Bankshares' impaired loans within the scope of SFAS No.
     114 include nonaccrual loans (excluding those collectively reviewed for
     impairment), troubled debt restructurings and certain other nonperforming
     loans.  For collateral dependent loans, Bankshares based the measurement of
     these impaired loans on the fair value of the loan's underlying collateral.
     For all other loans, Bankshares bases the measurement of these impaired
     loans on the more readily determinable of the present value of expected
     future cash flows discounted at the loan's effective interest rate or the
     observable market price.  Impairment losses are recognized through an
     increase in the allowance for loan losses and a corresponding charge to the
     provision for loan losses.  Adjustments to impairment losses due to changes
     in the fair value of impaired loans' underlying collateral are included in
     the provision for loan losses.  When an impaired loan is either sold,
     transferred to foreclosed properties or written down, any related valuation
     allowance is charged off against the allowance for loan losses.

     The adoption of SFAS No. 114, as amended by SFAS No. 118, did not have a
     material impact on Bankshares' consolidated financial statements due to
     Bankshares' continuing policy of measuring loan impairment based on the
     fair value of the underlying collateral which is consistent with the
     methods prescribed in SFAS No. 114.  In addition, Bankshares had previously
     reclassified in-substance foreclosures from other real estate owned to
     loans as of December 31, 1993 as prescribed by SFAS No. 114; therefore, no
     further reclassification from other real estate owned to loans was required
     upon adoption.

                  Notes to Consolidated Financial Statements

     As of September 30, 1995, the recorded investment in impaired loans was
     $821 and the amount of the related allowance for loan losses was $421 for
     a net investment of $400.

     During the nine months ended September 30, 1995, the average recorded
     investment in impaired loans was $811, and the total interest income
     recognized on impaired loans was $39, none of which was recognized on the
     cash basis.

     The following table presents information concerning nonperforming assets.

     Other real estate, acquired through foreclosure or deed in lieu of
     foreclosure, is carried at the lower of the recorded investment or its fair
     value, less estimated costs to sell (net realizable value).  When the
     property is acquired, any excess of the loan balance over net realizable
     value is charged to the allowance for loan losses.  Increases or decreases
     in the net realizable value of such properties are credited or charged to
     income by adjusting the valuation allowance for other real estate owned.
     Net costs of maintaining or operating foreclosed properties are expensed as
     incurred.

     The effective tax rate and the components of income tax expense do not
     differ significantly from such amounts disclosed in prior periods.

     Bankshares has determined that a valuation allowance for the gross deferred
     tax assets is not necessary at September 30, 1995 due to the fact that the
     realization of the entire gross deferred tax assets can be supported by the
     amount of taxes paid during the carryback period available under current
     tax laws.

     Total income taxes are allocated as follows:

                         Independent Auditor's Report


To the Board of Directors and Stockholders
of Bank of Tazewell County:


    We have audited the accompanying balance sheets of Bank of Tazewell County
as of December 31, 1994 and 1993, and the related statements of earnings,
changes in stockholders' equity and cash flows for each of the years in the
three-year period ended December 31, 1994. These financial statements are the
responsibility of the Bank's management. Our responsibility is to express an
opinion on these financial statements based on our audits.

    We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audit provides a reasonable basis for our opinion.

    In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Bank of Tazewell County as
of December 31, 1994 and 1993, and the results of its operations and its cash
flows for each of the years in the three-year period ended December 31, 1994 in
conformity with generally accepted accounting principles.

1.  THE SIGNIFICANT ACCOUNTING POLICIES OF BANK OF TAZEWELL COUNTY ARE AS
    FOLLOWS:

    Organization
    The Bank of Tazewell County is a state bank located in Tazewell, Virginia
    with branches in Bluefield, Virginia. The majority of the Bank's operations
    are conducted within Tazewell County.

    Investments in Securities
    The Bank's investments in securities are classified in three categories and
    accounted for as follows.

         Trading Securities
         ------------------
         Government bonds held principally for resale in the near term are
         classified as trading securities and recorded at their fair values.
         Realized and unrealized gains and losses on trading securities are
         included in other income.

         Securities to be Held to Maturity
         ---------------------------------
         Bonds, notes and debentures for which the Bank has the positive intent
         and ability to hold to maturity are reported at cost, adjusted for
         amortization of premiums, and accretion of discounts which are
         recognized in interest income using the interest method over the period
         to maturity.

         Securities Available for Sale
         -----------------------------
         Securities available for sale consist of bonds, notes, debentures and
         certain equity securities not classified as trading securities or as
         securities to be held to maturity.

    Declines in the fair value of individual held-to-maturity and available-for-
    sale securities below their cost that are other than temporary have resulted
    in write-downs of the individual securities to their fair value. The related
    write-downs have been included in earnings as realized losses.

    Unrealized holding gains and losses, net of tax, on securities available for
    sale are reported as a net amount in a separate component of shareholders'
    equity until realized.

    Gains and losses on the sale of securities available for sale are determined
    using the specific identification method.

    Loans
    Loans are stated at the amount of unpaid principal, reduced by any unearned
    discount included and an allowance for credit losses. Interest income on
    commercial and real estate loans is credited to operations based upon the
    principal amount outstanding. Interest income on installment loans is
    accrued and credited to operating income on the sum-of-the-digits method
    over the life of each loan. Accrual of interest is discontinued on a loan
    when management believes, after considering economic and business conditions
    and collection efforts, that the borrower's financial condition is such that
    collection of interest is doubtful.

1.  THE SIGNIFICANT ACCOUNTING POLICIES OF BANK OF TAZEWELL COUNTY ARE AS
    FOLLOWS:

    Allowance for Loan Losses
    The allowance is maintained at a level adequate to absorb probable losses.
    Management determines the adequacy of the allowance based upon reviews of
    individual credits, recent loss experience, current economic conditions, the
    risk characteristics of the various categories of loans, and other pertinent
    factors. Credits deemed uncollectible are charged to the allowance.
    Provisions for loan losses and recoveries on loans previously charged off
    are added to the allowance.

    Bank Premises and Equipment
    Land is stated at cost. Bank premises and equipment are stated at cost, less
    accumulated depreciation. Depreciation is computed on the straight-line and
    declining balance methods over the useful lives of the assets, which range
    from five to forty years. The costs of major improvements are capitalized.
    The expenditures for maintenance and repairs are charged to expense as
    incurred. Gains or losses on assets sold are included in other operating
    income and appropriate adjustments are made to the accumulated depreciation
    account.

    Income Taxes
    Provisions for income taxes are based on amounts reported in the statement
    of income (after exclusion of nontaxable income such as interest on state
    and municipal securities) and include deferred taxes on temporary
    differences in the recognition of income and expense for tax and financial
    statement purposes. Deferred tax assets and liabilities are included in the
    financial statements at currently enacted income tax rates applicable to the
    period in which the deferred tax assets and liabilities are expected to be
    realized or settled as prescribed in SFAS No. 109, "Accounting for Income
    Taxes." As changes in tax laws or rates are enacted, deferred tax assets and
    liabilities are adjusted through the provision for income taxes.

    Pension Costs
    The Bank maintains a noncontributory, trusteed pension plan for the benefit
    of eligible employees meeting certain service and age requirements. It is
    the Bank's policy to fund accrued pension cost. Prior service costs are
    being amortized over ten years.

    Trust Assets and Income
    Assets held by Bank of Tazewell County in a fiduciary or agency capacity for
    its customers are not included in the Balance Sheets since such items are
    not assets of the Bank. Trust Department income is recognized on the cash
    basis of accounting which in this instance is not materially different from
    reporting on the accrual basis of accounting.

    Cash Equivalents For purposes of the Statements of Cash Flows, the Bank
    considers all highly liquid debt instruments purchased with a maturity of
    three months or less to be cash equivalents.

    Fair Values of Financial Instruments
    The following methods and assumptions were used by the Bank in estimating
    fair values of financial instruments as disclosed herein:

         Cash and Cash Equivalents
         -------------------------
         The carrying amounts of cash and short-term instruments approximate
         their fair value.

1.  THE SIGNIFICANT ACCOUNTING POLICIES OF BANK OF TAZEWELL COUNTY ARE AS
    FOLLOWS:

         Trading Securities
         ------------------
         Fair values for trading account securities which also are the amounts
         recognized in the balance sheet, are based on quoted market prices,
         where available. If quoted market prices are not available, fair values
         are based on quoted market prices of comparable instruments.

         Securities to be Held to Maturity and Securities Available for Sale
         -------------------------------------------------------------------
         Fair values for investment securities, excluding restricted equity
         securities, are based on quoted market prices. The carrying values of
         restricted equity securities approximate fair values.

         Loans Receivable
         ----------------
         For variable-rate loans that reprice frequently and with no significant
         change in credit risk, fair values are based on carrying values. Fair
         values for real estate and commercial loans are estimated using
         discounted cash flow analyses, using interest rates currently being
         offered for loans with similar terms to borrower of similar credit
         quality. Fair values for impaired loans are estimated using discounted
         cash flow analyses or underlying collateral values, where applicable.

         Deposit Liabilities
         -------------------
         The fair values disclosed for demand deposits are, by definition, equal
         to the amount payable on demand at the reporting date (that is, their
         carrying amounts). The carrying amounts of variable-rate, fixed-term
         money market accounts and certificates of deposit approximate their
         fair values at the reporting date. Fair values for fixed-rate
         certificates of deposit are estimated using a discounted cash flow
         calculation that applies interest rates currently being offered on
         certificates to a schedule of aggregated expected monthly maturities on
         time deposits.

2.  RESTRICTIONS ON CASH AND DUE FROM BANK ACCOUNTS:

    The Bank is required to maintain an average reserve balance with the Federal
    Reserve Bank. The average amount of the reserve balance was approximately
    $148 at December 31, 1994, 1993 and 1992.

3.  INVESTMENT SECURITIES:

    The carrying amounts of investment securities as shown in the consolidated
    balance sheets of the Bank and their approximate full values at December 31
    were as follows:

9. PENSION PLAN:
      
    The Bank has a defined benefit pension plan covering substantially all of
    its employees. The plan provides normal, early, late, death and disability
    retirement benefits based on an average of qualifying compensation for the
    highest five consecutive calendar years, excluding the year of
    determination. The Bank's policy is to contribute annually the maximum
    amount that can be deducted for federal income tax purposes. Contributions
    are intended to provide not only for benefits attributed to service to date
    but, also for those expected to be earned. Actuarially determined
    contributions of the Pension Plan were $203 and $186 and $81 in 1994, 1993
    and 1992, respectively.

    The Bank accounts for pension costs by use of Financial Accounting Standard
    No. 87, "Employers' Accounting for Pensions," and No. 88, "Employers'
    Accounting for Settlements and Curtailments of Defined Benefit Pension Plans
    and for Termination Benefits."

    The discount rate used was 7% for 1994, 7% for 1993 and 8% for 1992 and the
    rate of increase in future compensation levels used was 5% in each year in
    determining the actuarial present value of the projected benefit obligation.

11.  RELATED PARTY TRANSACTIONS:

     Officers and directors are loan customers in the ordinary course of
     business.  These loans are made on substantially the same terms as those
     prevailing at the time for comparable loans with other persons and do not
     involve more than normal risk of collectibility or present other
     unfavorable features.  These loans amounted to $2,115, $1,727 and $1,137 at
     December 31, 1994, 1993 and 1992, respectively.

12.  CONTINGENT LIABILITIES AND COMMITMENTS:

     The Bank's financial statements do not reflect various commitments and
     contingent liabilities that arise in the normal course of business and that
     involve elements of credit risk, interest rate risk and liquidity risk.
     These commitments and contingent liabilities are commitments to extend
     credit, commercial letters of credit and standby letters of credit,
     generally at variable interest rates.  A summary of the Bank's commitments
     and contingent liabilities at December 31, 1994 and 1993 is as follows:

                                 ======        =====       
</TABLE>


     Commitments to extend credit, commercial letters of credit and standby
     letters of credit all include exposure to some credit loss in the event of
     nonperformance of the customer.  The Bank's credit policies and procedures
     for credit commitments and financial guarantees are the same as those for
     extension of credit that are recorded on the balance sheets.  Because these
     instruments have fixed maturity dates, and because many of them expire
     without being drawn upon, they do not generally present any significant
     liquidity risk to the Bank.  The Bank has not incurred any losses on its
     commitments in either 1994, 1993 or 1992.

13.  RENTAL EXPENSE:

     The Bank leases its Westgate branch facility under a noncancellable
     agreement which expires September 19, 2003, with an annual rental of $13.
     The total minimum rental commitment at December 31, 1994, under this lease,
     is $114 which is due as follows:

15.  CONCENTRATIONS OF CREDIT:

     All of the Bank's loans, commitments, and commercial and standby letters of
     credit have been granted primarily to customers in the Bank's market area.
     Essentially all such customers are depositors of the Bank.  The
     concentrations of credit by type of loan are set forth in Note 4.  The
     distribution of commitments to extend credit approximates the distribution
     of loans outstanding.  Commercial and standby letters of credit were
     granted primarily to commercial borrowers.  The Bank, as a matter of
     policy, does not extend credit to any single borrower or group of related
     borrowers in excess of the Bank's legal lending limit.

16.  STOCK DIVIDEND:

     The Board of Directors authorized a 200% stock dividend on the Banks $1 par
     value common stock payable February 1, 1995 to stockholders of record on
     January 20, 1995.  As a result of this dividend, 1,258,806 additional
     shares were issued and retained earnings was reduced by $1,258,806.  All
     references in the accompanying financial statements to the number of common
     shares and per share amounts have been restated to reflect the stock
     dividend which was accounted for as a stock split.

    Bank of Tazewell County does not have a formal nonaccrual policy. A loan is
    placed on nonaccrual when, in the judgment of management, it is doubtful
    that full principal and interest will be collected.

    The following table shows the interest that would have been earned on
    nonaccrual and restructured loans if they had been current in accordance
    with their original terms and the recorded interest that was earned and
    included in income on these loans:

    Other real estate, acquired through foreclosure or deed in lieu of
    foreclosure, is carried at the lower of the recorded investment or its fair
    value, less estimated costs to sell (net realized value). When the property
    is acquired, any excess of the loan balance over net realizable value is
    charged to the allowance for loan losses. Increases or decreases in the net
    realizable value of such properties are credited or charged to income by
    adjusting the valuation allowance for other real estate owned. Net costs of
    maintaining or operating foreclosed properties are expensed as incurred.

</TABLE>

    The effective tax rate and the components of income tax expense do not
    differ significantly from such amounts disclosed in prior periods.

    The Bank has determined that a valuation allowance for the gross deferred
    tax assets is not necessary at September 30, 1995 due to the fact that the
    realization of the entire gross deferred tax assets can be supported by the
    amount of taxes paid during the carryback period available under current tax
    laws.
 
Total income taxes were allocated as follows:

     obligations representing any such rights are outstanding.  Neither NBI,
     NBB, nor BTC has granted or made any commitment to grant any options or
     share appreciation rights with respect to the BTC Common Stock, the NBI
     Common Stock, or the NBB Stock, as the case may be.

          (D) This Transaction.  NBI will, prior to the Merger Effective Date,
     own 100% of the outstanding shares ("NBI Interim Bank Common Stock") of a
     duly chartered Virginia bank ("NBI Interim Bank") and the Boards of
     Directors of NBI and BTC, respectively, deem it advisable and in the best
     interests of NBI and BTC and their stockholders that BTC be acquired by NBI
     through a merger of NBI Interim Bank into BTC pursuant to this Agreement
     and Plan of Merger.

          (E) Approvals.  The Board of Directors of each of NBI and BTC has
     approved and adopted, at meetings of each of such Board of Directors, this
     Plan and has authorized, subject to such further modifications as may be
     agreed by the Presidents of NBI and BTC, respectively, not inconsistent
     herewith, the execution hereof in counterparts.  At the meeting of the BTC
     Board of Directors, the Board of Directors of BTC recommended the Plan as
     so executed to its shareholders.

                                      A-1

          (F) Share Dividend.  In connection with the consummation of this Plan,
     it is intended that NBI shall cause a share dividend totalling 190,768
     shares of NBI Common Stock to be declared and issued pro rata to and among
     the holders of shares of NBI Common Stock in accordance with the provisions
     of Paragraph (F) of Article II.

          (G) NASDAQ.  Trading of the NBI Common Stock and BTC Common Stock,
     respectively, is presently reflected on the Over the Counter Electronic
     Bulletin Board ("NASD Bulletin Board") of the National Association of
     Securities Dealers ("NASD").

          (H) Benefits of Plan.  NBI and BTC believe the Plan and its
     consummation are in the respective best interests of each corporation and
     its shareholders for the following reasons, among others:  (1) the Merger
     will allow them to provide banking and related financial services more
     effectively and efficiently; (2) the Merger will expand the range of
     banking and related financial services which they can provide; (3) the
     Merger will enhance the safety and soundness of their operations; (4) the
     Merger will enable them to expand the market for their banking and related
     financial services; and (4) the Merger will expand the number and diversity
     of their shareholder bases and enhance the liquidity of such investments.

          NOW, THEREFORE, in consideration of their mutual promises and
     obligations, the parties hereto adopt and make this Plan and prescribe the
     terms and conditions thereof and the manner and basis of carrying it into
     effect, which shall be as follows:

                                 I.  THE MERGER

          (A) The Continuing Corporation.  On the Merger Effective Date (as
     hereinafter defined), NBI Interim Bank shall merge into BTC (the "Merger"),
     the separate existence of NBI Interim Bank shall cease and BTC (the
     "Continuing Corporation") shall survive.

          (B) Rights, Etc.  Upon consummation of the Merger, the Continuing
     Corporation shall thereupon and thereafter possess all of the rights,
     privileges, immunities and franchises, of a public as well as of a private
     nature, of each of the merging corporations; and all property, real,
     personal and mixed, and all debts due on whatever account, and all other
     choses in action, and all and every other interest, of or belonging to or
     due to each of the corporations so merged, shall be deemed to be vested in
     the Continuing Corporation without further act or deed; and the title to
     any real estate or any interest therein, vested in any of such
     corporations, shall not revert or be in any way impaired by reason of the
     Merger as provided by the laws of the Commonwealth of Virginia.

          (C) Liabilities.  Upon consummation of the Merger, the Continuing
     Corporation shall thenceforth be responsible and liable for all the
     liabilities, obligations and penalties of each of the corporations so
     merged.

          (D) Articles of Incorporation; Bylaws; Directors; Officers of
     Continuing Corporation.  The Articles of Incorporation of the Continuing
     Corporation shall be those of BTC, as amended pursuant to the Charter
     Amendment as more particularly described in Paragraph (B) of Article V, and
     the Bylaws of the Continuing Corporation shall be those of BTC, as amended
     pursuant to the requirements of Paragraph (K) of Article V.  The officers
     and directors of BTC in office immediately prior to the Merger becoming
     effective shall be the officers and directors of the Continuing
     Corporation, who shall hold office until such time as their successors are
     elected and qualified in accordance with the Articles and Bylaws of the
     Continuing Corporation.

          (E) Merger Closing; Merger Effective Date.  The Merger shall become
     effective at 11:59 p.m. on the date the Virginia State Corporation
     Commission ("SCC") issues a certificate of merger reflecting the Merger
     (the "Merger Effective Date").  Unless otherwise agreed upon in writing by
     the chief executive officers of NBI and BTC, subject to the conditions to
     the obligations of the parties to effect the Merger as set forth in Article
     VI, the parties shall use their reasonable efforts to cause the Merger
     Effective Date to occur as soon as practicable following the satisfaction
     of the conditions set forth in Paragraphs (A), (B) and (C) of Article VI.
     All documents required by the

                                      A-2
<PAGE>
 
     terms of this Agreement to be delivered at or prior to consummation of the
     Merger will be exchanged by the parties at the closing of the Merger (the
     "Merger Closing"), which shall be held on the Merger Effective Date at the
     principal executive offices of NBI (or at such other location as may be
     mutually agreed upon by the parties). Prior to the Merger Closing, NBI
     Interim Bank and BTC shall execute and deliver to the SCC, Articles of
     Merger containing a Plan of Merger in substantially the form of Exhibit A
                                                                     ---------
     hereto (the "Plan of Merger").

          (F) Bylaws and Directors of NBI.  Effective as of the Merger Effective
     Date, NBI shall cause its Bylaws to be amended as follows:  (1) the number
     of NBI directors shall be set at nine (9); (2) the affirmative vote of six
     (6) out of the nine (9) NBI directors shall be required to approve any of
     the following actions:  (a) membership on the Board of Directors of the
     Continuing Corporation (provided, however, that notwithstanding the
     foregoing, a director of the Continuing Corporation may be removed by
     action of NBI as sole shareholder of the Continuing Corporation authorized
     by the vote of a simple majority of NBI directors in the event that such
     director commits a violation of law applicable to his duties as a director
     of the Continuing Corporation which has a material adverse financial affect
     on the Continuing Corporation or engages in any conduct in connection with
     his duties as a director for which he would not be entitled to
     indemnification under the Articles of Incorporation of the Continuing
     Corporation); (b) amendments to the Articles of Incorporation or Bylaws of
     the Continuing Corporation; (c) the merger, consolidation or sale of all or
     substantially all of the assets of the Continuing Corporation; and (d) a
     recommendation to the shareholders of NBI to merge, consolidate or sell all
     or substantially all of the assets of NBI, where such recommendation is
     required by law; (3) to change the provisions requiring that NBI directors
     also be NBB directors to permit BTC directors to serve on the NBI Board as
     well; and (4) the Executive Committee shall not authorize or approve any
     action on behalf of NBI described in Paragraph (2) hereof.  NBI agrees that
     the foregoing Bylaw amendments shall not be amended or rescinded by action
     of its Board of Directors without the affirmative vote of at least six (6)
     directors until January 1, 2001, on and after which time such Bylaw
     amendments may be amended or rescinded by a simple majority vote of its
     Board of Directors as provided in the Bylaws of NBI.

          (G) NBI Corporate Actions.  Effective as of the Merger Effective Date,
     NBI shall obtain the resignations of five directors currently serving on
     the NBI Board of Directors spread as nearly equally as possible among the
     three classes of NBI directors, thereby reducing the number of persons then
     serving on the NBI Board of Directors to five and, in conjunction with the
     amendment to the NBI Bylaws referred to in (F)(1) above, creating four
     vacancies on the NBI Board of Directors ("NBI Board Vacancies").  NBI
     agrees that the remaining five NBI directors shall fill the NBI Board
     Vacancies with four persons selected by BTC ("BTC Board Representatives")
     from among the current members of the BTC Board of Directors by electing
     them to the NBI Board Vacancies until the next following annual
     shareholders meeting.  NBI further agrees that, unless any BTC Board
     Representative's service on the Board is terminated for cause in accordance
     with the provisions of NBI's Articles of Incorporation, it shall renominate
     the BTC Board Representatives for reelection to the remaining term of their
     respective classes at the next annual shareholders meeting following the
     Merger Effective Date and shall continue to renominate for reelection by
     the NBI shareholders those of the BTC Board Representatives who must stand
     for reelection as a result of the expiration of their class term as of the
     NBI annual shareholders meetings in 1997, 1998, 1999, and 2000,
     respectively.  In the event of the death or resignation of any BTC Board
     Representative creating a vacancy on the NBI Board of Directors at any time
     before the NBI annual shareholders meeting in 2000, the Board of the
     Continuing Corporation shall be entitled to select a replacement to fill
     such vacancy and the NBI Board shall elect such replacement to fill the
     vacancy created by such death or resignation.  Thereafter, such replacement
     director shall be deemed to be a BTC Board Representative within the
     meaning of this Paragraph (G).  On the Merger Effective Date, or as soon
     thereafter as practicable, the NBI Board of Directors shall appoint an
     Executive Committee consisting of five (5) of its members, two (2) of whom
     shall be BTC Board Representatives.

                           II.  MERGER CONSIDERATION

          (A) Outstanding NBI Interim Bank Common Stock.  Each share of NBI
     Interim Bank Common Stock issued and outstanding immediately prior to the
     Merger Effective Date, on and after the Merger Effective Date, shall be
     converted automatically into 1,888.209 shares of common stock of the
     Continuing Corporation and shall constitute the only issued and outstanding
     shares of common stock of the Continuing Corporation.

                                      A-3
<PAGE>
 
          (B) Outstanding BTC Common Stock.  Each share (excluding shares held
     by BTC or by NBI or by its subsidiary, in each case other than in a
     fiduciary capacity or as a result of debts previously contracted) of BTC
     Common Stock issued and outstanding immediately prior to the Merger
     Effective Date shall, by virtue of the Merger, automatically and without
     any action on the part of the holder thereof on the Merger Effective Date,
     become and be converted into the right to receive one share of NBI Common
     Stock (the "Exchange Ratio"), it being understood that such Exchange Ratio
     takes into account the share dividend to be declared by the NBI Board of
     Directors as set forth in Paragraph (F) below.


          (C) Stockholder Rights; Stock Transfers.  On the Merger Effective
     Date, holders of BTC Common Stock shall cease to be, and shall have no
     rights as, stockholders of BTC other than to receive the Merger
     consideration provided under Paragraph (B) above and Paragraph (D) below.
     After the Merger Effective Date, there shall be no transfers on the stock
     transfer books of BTC or the Continuing Corporation of the shares of BTC
     Common Stock which were issued and outstanding immediately prior to the
     Merger becoming effective.

          (D) Fractional Shares.  Notwithstanding any other provision hereof, no
     fractional shares of NBI Common Stock and no certificates or scrip
     therefor, or other evidence of ownership thereof, will be issued in the
     Merger; instead, NBI shall pay to each holder of BTC Common Stock who would
     otherwise be entitled to a fractional share an amount in cash determined by
     multiplying such fractional share by the closing sale price of BTC Common
     Stock for the final bona fide trade on the last day on which such stock has
     traded prior to the Merger Effective Date, as reflected in the NASD
     Bulletin Board.

          (E) Exchange Procedures.  As promptly as practicable after the Merger
     Effective Date, NBI shall send or cause to be sent to each former
     stockholder of BTC of record immediately prior to the Merger Effective Date
     transmittal materials for use in exchanging such stockholder's certificates
     of BTC for the consideration set forth in Paragraphs (B) and (D) above.
     Any fractional share checks which a BTC stockholder shall be entitled to
     receive in exchange for such stockholder's shares of BTC Common Stock, and
     any dividends paid on any shares of NBI Common Stock, that such stockholder
     shall be entitled to receive prior to the delivery to NBI of such
     stockholder's certificates representing all of such stockholder's shares of
     BTC Common Stock will be delivered to such stockholder only upon delivery
     to NBI of the certificates representing all of such shares (or indemnity
     satisfactory to NBI, in its judgment, after consultation with the President
     of the Continuing Corporation, if any of such certificates are lost, stolen
     or destroyed).  No interest will be paid on any such fractional share
     checks or dividends which the holder of such shares shall be entitled to
     receive upon such delivery.  After the Merger Effective Date, to the extent
     permitted by law, former stockholders of record of BTC shall be entitled to
     vote at any meeting of holders of NBI Common Stock, the number of whole
     shares of NBI Common Stock into which their respective shares of BTC Common
     Stock are converted, regardless of whether such holders have exchanged
     their certificates representing BTC Common Stock for certificates
     representing NBI Common Stock in accordance with the provisions of this
     Plan.

          (F) Share Dividend.  NBI agrees to increase the number of shares of
     NBI Common Stock issued and outstanding by means of a stock dividend
     totalling 190,768 shares of NBI Common Stock, the record date therefor
     which shall be prior to the Merger Effective Date; provided, however, that
     NBI shall not be required to declare such stock dividend until:  (1)
     satisfaction of the conditions set forth in Paragraphs (A), (B) and (C) of
     Article VI; and (2) such time as BTC acknowledges in writing that all
     conditions to its obligation to consummate the Merger (and BTC's right to
     terminate this Plan) have been waived or satisfied.

          (G) Shares Held by BTC or NBI.  Each of the shares of BTC Common Stock
     held by BTC, by NBI or its subsidiary, in each case other than in a
     fiduciary capacity or as a result of debts previously contracted, shall be
     canceled and retired at the Merger Effective Date and no consideration
     shall be issued in exchange therefor.

          (H) Dissenting Stockholders.  Any holder of shares of BTC Common Stock
     who perfects his dissenters' rights of appraisal in accordance with and as
     contemplated by Article 15 of the Virginia Stock Corporation Act shall be
     entitled to receive the value of such shares in cash as determined pursuant
     to the provision of such law; provided, however, that no such payment shall
                                   --------  -------                            
     be made to any dissenting stockholder unless and until such dissenting

                                      A-4
<PAGE>
 
     stockholder has complied with the applicable provisions of the Virginia
     Stock Corporation Act and duly surrendered the certificate or certificates
     representing the shares for which payment is being made.  In the event that
     a dissenting BTC shareholder fails to perfect, or effectively withdraws or
     loses, his right to appraisal and payment for his shares, after the Merger
     Effective Date, NBI shall issue and deliver the consideration to which such
     holder of BTC Common Stock is entitled under Article II (without interest)
     upon surrender by such holder of the certificate or certificates
     representing shares of BTC Common Stock held by him.

                          III.  ACTIONS PENDING MERGER

     A.   Without the prior written consent or approval of a proper officer of
     the other party, BTC and NBI will not and NBI will cause its subsidiary

     dividend paid prior hereto by NBI or BTC, as the case may be (provided,
     however, that in the case of BTC, it may at its option accelerate the
     record and payment dates of its semi-annual cash dividend, if any, which
     would regularly in accordance with past practice be payable in January,
     1996 or July, 1996 ("BTC January or July cash dividend", as the case may
     be) so that the record and payment dates of the BTC January or July cash
     dividend, as the case may be, occur prior to the Merger Effective Date if
     the Merger Effective Date will occur:  (a) after the record date of the
     second semi-annual NBI cash dividend, if any, for 1995 which would
     regularly in accordance with past practices be payable in December, 1995,
     but prior to the BTC January cash dividend if it were not so accelerated or
     (b) after the record date of the first semi-annual NBI cash dividend, if
     any, for 1996 which would regularly in accordance with past practices be
     payable in June, 1996 but prior to the BTC July cash dividend if it were
     not so accelerated) and any limitations on the payment of dividends
     Previously Disclosed or declare or make any distribution on, or directly or
     indirectly combine, redeem, reclassify, purchase or otherwise acquire, any

     ordinary course of its business and consistent with past practice or in
     connection with stock received on a debt previously contracted basis) or
     authorize the creation or issuance of, or issue, any additional shares of
     its capital stock, or any options, calls or commitments relating to its

     acquire from its shares of its capital stock or any securities or
     obligations convertible into or exchangeable for shares of its capital
     stock, or issue any long-term debt;

          (2) Employment Contracts.  Enter into any employment contracts with,

     except in accordance with plans or agreements existing and as in effect on
     the date hereof and Previously Disclosed;

          (3) Employee Benefit Plans.  Enter into or modify (except as may be
     required by applicable law) any pension, retirement, stock option, stock
     purchase, savings, profit sharing, deferred compensation, consulting,
     bonus, group insurance or other employee benefit, incentive or welfare
     contract, plan or arrangement, or any trust agreement related thereto, in
     respect of any of its directors, officers or other employees, including
     without limitation taking any action that accelerates (1) the vesting or
     exercise of any benefits payable thereunder, or (2) the right to exercise
     any employee stock options or stock appreciation rights outstanding
     thereunder;

          (4) Asset Disposition.  Dispose of, grant an encumbrance against or
     discontinue any portion of its assets, business or properties, which is
     material to BTC or to NBI and its subsidiary taken as a whole, as the case
     may be, or merge or consolidate with, or acquire all or any substantial
     portion of, the business or property of any other entity (except
     foreclosures, acquisitions of control in its fiduciary capacity or
     securitization transactions, in each case in the ordinary course of
     business consistent with past practice or the formation and capitalization
     of NBI Interim Bank by NBI in accordance with the Plan);

     Bylaws except as contemplated by this Plan.  True and correct copies of its
     Articles of Incorporation and Bylaws have been delivered to the other;

     execution hereof, it shall cause to be formed a Virginia corporation which
     shall be named and become NBI Interim Bank.  The authorized capital stock
     of NBI Interim Bank shall consist of 50,000 shares of common stock, $1.00
     par value, of which 1,000 shares shall be subscribed for by NBI pending
     consummation of the Plan.  NBI shall file any governmental applications
     necessary to qualify NBI Interim Bank to merge with BTC as contemplated
     hereby.  NBI shall cause NBI to execute the Articles of Merger and to take
     all steps necessary to consummate the Merger provided that no such steps
     need be taken which materially adversely impacts the economic or business
     benefits of the transactions contemplated by this Plan so as to render
     inadvisable the consummation of the Merger.

                      IV.  REPRESENTATIONS AND WARRANTIES

          BTC hereby represents and warrants to NBI, and NBI hereby represents

     in all of the properties and assets thereof reflected as owned or leased in
     its balance sheet as of December 31, 1994, and included in the Financial
     Reports as hereinafter defined and in all properties and assets acquired or
     leased by it or, in the case of NBI, its subsidiary, since December 31,

     (1) mechanic's, carrier's, worker's or similar liens arising in the
     ordinary course of business; (2) as Previously Disclosed; (3) imperfections

     subsidiary taken as a whole; and (4) liens of current taxes not due and

     necessary corporate action of it and is a valid and binding agreement of it
     enforceable against it in accordance with its terms, subject to (1)

                                      A-6
<PAGE>
 
     under, any law, rule or regulation or any judgment, decree, order,
     governmental permit or license, franchise or agreement, indenture,
     instrument or authorization of or held by it or, in the case of NBI, its
     subsidiary or to which it or, in the case of NBI, its subsidiary or their
     respective properties is subject or bound, which breach, violation or
     default is reasonably likely to have a Material Adverse Effect on it; or
     (2) a breach or violation of, or a default under, its Articles of
     Incorporation or Bylaws;

          (F)   Financial Reports.  Except as Previously Disclosed, (1) in the

     Reports") did not and will not contain any untrue statement of a material
     fact or omit to state a material fact required to be stated therein or
     necessary to make the statements made therein, in light of the
     circumstances under which they were made, not misleading; and each of the
     balance sheets in or incorporated by reference into the Financial Reports

     to the extent not prohibited by law, all reports of any state or federal
     regulatory authority relating to it or, in the case of NBI, NBB and
     received during or relating to matters in 1994 or 1995 (all of the

          (H)   Material Events.  Except as Previously Disclosed, since December

     manner relates to the capital, liquidity, credit policies or management of
     it or, in the case of NBI, NBB; and, 

                                      A-7

     date hereof;

          (K)   Commissions.  All negotiations relative to this Plan and the
     transactions contemplated hereby have been carried on by it directly with

     subsidiaries (the "Employees") are Previously Disclosed, true and complete
     copies of which have been made available to the other party;

                (2) all employee benefit plans covering Employees, to the extent
     subject to ERISA (the "ERISA Plans"), are in compliance with ERISA, except
     for failure to so comply which are not reasonably likely, individually or
     in the aggregate, to have a Material Adverse Effect on it; each ERISA Plan
     which is an "employee pension benefit plan" within the meaning of Section
     3(2) of ERISA ("Pension Plan") and which is intended to be qualified under
     Section 401(a) of the Internal Revenue Code of 1986, as amended (the
     "Code"), has either (a) received a favorable determination letter from the
     Internal Revenue Service, or (b) is or will be the subject of an
     application for a favorable determination letter, and it is not aware of
     any circumstances likely to result in the revocation or denial of any such
     favorable determination letter; there is no pending or, to the best of its
     knowledge, threatened litigation relating to the ERISA Plans which is
     reasonably likely, individually or in the aggregate, to have a Material
     Adverse Effect on it; and neither it nor, in the case of NBI, NBB has
     engaged in a transaction with respect to any ERISA Plan that, assuming the
     taxable period of such transaction expired as of the date hereof, would
     subject it or, in the case of NBI, NBB to a tax or penalty imposed by
     either Section 4975 of the Code or Section 502(i) of ERISA in an amount
     which is reasonably likely, individually or in the aggregate, to have a
     Material Adverse Effect on it;

                (3) no liability under Subtitle C or D of Title IV of ERISA has
     been or is expected to be incurred by it or, in the case of NBI, NBB with
     respect to any ongoing, frozen or terminated "single-employer plan", within
     the meaning of Section 4001(a)(15) of ERISA, currently or formerly
     maintained by any of them or any entity which is considered one "employer"
     with it under Section 4001(a)(14) of ERISA or Section 414 of the Code (an
     "ERISA Affiliate"), which liability is reasonably likely to have a Material
     Adverse Effect on it; it and its subsidiaries have not incurred and do not
     expect to incur any withdrawal liability with respect to a multiemployer
     plan under Subtitle E of Title IV of ERISA; and to its knowledge no notice
     of a "reportable event" within the meaning of Section 4043 of ERISA for
     which the 30-day reporting requirement has not been waived, has been
     required to be filed for any Pension Plan or the Pension Plan of an ERISA
     Affiliate within the 12-month period ending on the date hereof;

                (4) during the current plan year and the immediately preceding
     three plan years of such ERISA Plan, all contributions required to be made
     under the terms of any ERISA Plan of it, or in the case of NBI, NBB or an
     ERISA Affiliate have been timely made; and no pension plan of it, in the
     case of NBI, NBB, or an ERISA Affiliate has an "accumulated funding
     deficiency" (whether or not waived) within the meaning of Section 412 of
     the 

                                      A-8
<PAGE>
 
     Code or Section 302 of ERISA which is reasonably likely, individually
     or in the aggregate, to have a Material Adverse Effect on it;

                (5) under each Pension Plan which is a single-employer plan, as
     of the last day of the most recent plan year ended prior to the date
     hereof, the actuarially determined present value of all "benefit
     liabilities", within the meaning of Section 4001(a)(16) of ERISA (as
     determined on the basis of the actuarial assumptions contained in the ERISA
     Plan's most recent actuarial valuation) did not exceed the then current
     value of the assets of such ERISA Plan, and there has been no material
     adverse change in the financial position of such ERISA Plan since the last
     day of the most recent plan year; and

                (6) there are no material current or projected liabilities for
     retiree health or life insurance benefits;

          (M)   Regulatory Approvals.  It knows of no reason why the regulatory
     approvals referred to in Paragraphs (B) and (C) of Article VI should not be
     obtained without the imposition of any condition of the type referred to in
     the proviso following such Paragraph (C);

          (N)   Subsidiaries.  In the case of BTC, it has no subsidiaries.  NBI
     has one subsidiary, which is NBB, and NBB has one subsidiary, which is NB
     Operating, Inc.;

     NBI, NBB is a party to, or is bound by any collective bargaining agreement,
     contract or other agreement or understanding with a labor union or labor
     organization, nor is it or in the case of NBI, NBB the subject of a
     proceeding asserting that it and in the case of NBI, NBB has committed an
     unfair labor practice (within the meaning of the National Labor Relations
     Act) or seeking to compel it or such subsidiary to bargain with any labor
     organization as to wages and conditions of employment, nor is there any
     strike or other labor dispute involving it or in the case of NBI, NBB
     pending or, to the best of its knowledge, threatened, nor is it aware of
     any activity involving it or in the case of NBI, NBB's employees seeking to
     certify a collective bargaining unit or engaging in any other organization
     activity;

          (P)   Classified Assets. (1) NBI has Previously Disclosed a list of
     the aggregate amounts of loans, extensions of credit or other assets of
     NBB, that have been classified as of June 30, 1995 by NBB ("NBB Asset
     Classification") and (2) BTC has Previously Disclosed a list of the loans,
     extensions of credit or other assets of BTC that were classified by the
     examiners of the Board of Governors of the Federal Reserve System in its
     last preceding examination ("BTC Asset Classification") and has Previously
     Disclosed a list of its loans and extensions of credit by BTC in the
     respective initial principal amount of $100,000 or more, any payment of
     which is, as of the date so disclosed, delinquent ("BTC Delinquent Loan
     List"). The NBB Asset Classification, the BTC Asset Classification and the
     BTC Delinquent Loan List are, respectively, accurate and complete in all
     material respects and no amounts of loans, extensions of credit or other
     assets that have been classified as of the respective date of the NBB or
     BTC Asset Classification by any regulatory examiner as "Other Loans
     Specially Mentioned", "Substandard", "Doubtful", "Loss", or words of
     similar import are excluded from the amounts disclosed in the NBB or BTC
     Asset Classification as of the respective date thereof other than amounts
     of loans, extensions of credit or other assets that were charged off by BTC
     or NBB, as the case may be, prior to the respective date of the NBB or BTC
     Asset Classification;

          (Q)   Affiliates.  Except as Previously Disclosed, to the best of its
     knowledge, there is no person who, as of the date of this Plan, may be
     deemed to be an "affiliate" of BTC or NBI as that term is used in Rule 145
     under the Securities Act of 1933, as amended (together with the rules and
     regulations thereunder, the "Securities Act"; hereinafter the Securities
     Act and the Exchange Act are referred to as the "Federal Securities Laws");

          (R)   Insurance Policies.  It has made available to the other party
     correct and complete copies of all of its and in the case of NBI, NBB's
     insurance policies respecting the properties, operations, liabilities,
     officers, 

                                      A-9

     and effect or provide coverage to it, and in the case of NBI, NBB or their
     officers, directors and employees;

     in accordance with the terms of this Plan, will be validly issued, fully
     paid and nonassessable and subject to no preemptive rights;

     or any other action or combination of actions, or any other transactions,
     contemplated hereby or thereby do not and will not (1) require a vote of
     stockholders (other than as set forth in Paragraph (A) of Article VI); or
     (2) result in the grant of any rights to any person under its Articles of
     Incorporation or Bylaws or under any agreement; or (3) except as set forth
     in Paragraphs (B) and (C) of Article VI, require any consent or approval
     under any law, rule, regulation, judgment, decree, order, governmental

     not reasonably likely, individually or in the aggregate, to have a Material
     Adverse Effect on it;

                (2) there is no proceeding pending or, to its knowledge,
     threatened before any court, governmental agency or board or other forum in
     which it or in the case of NBI, NBB or any Participation Facility has been,

     date, (b) as expressly contemplated by this Plan, or (c) for
     representations and warranties (other than the representations and
     warranties set forth in Paragraph (A) of Article IV, which shall be true

     matters that, individually or in the aggregate, do not materially adversely
     affect the Merger and the other transactions contemplated by this Plan, and

     Revenue Code, and (2) no gain or loss will be recognized by stockholders of
     BTC who receive shares of NBI Common Stock in exchange for their shares of
     BTC Common Stock except that gain or loss may be recognized as to cash

          (N) NBI and BTC shall have received a letter, dated as of the Merger

                               VII. TERMINATION.

          This Plan may be terminated prior to the Merger Effective Date, either
     before or after receipt of required stockholder approval:

                                      A-18
<PAGE>
 
          (A) by the mutual consent of NBI and BTC, if the Board of Directors of
     each so determines by vote of a majority of the members of its entire
     Board;

          (B) by NBI or BTC, if its Board of Directors so determines by vote of
     a majority of the members of its entire Board, in the event of (1) a breach
     by the other party of any representation or warranty contained herein,
     which breach cannot be or has not been cured within thirty (30) days after
     the giving of written notice to the breaching party of such breach and
     which breaches, individually or in the aggregate, materially adversely
     affect the Merger and the other transactions contemplated by this Plan, or
     (2) a material breach by the other party of any of the covenants or
     agreements contained herein, which breach cannot be or has not been cured
     within thirty (30) days after the giving of written notice to the breaching
     party of such breach; provided, however, that a breach can only be asserted
     as a basis for termination pursuant to this paragraph (B) by a party who is
     not itself at such time in breach hereof and provided, further, that
     termination under this Paragraph (B) shall not relieve any party from
     liability under Paragraph (E)(2) of Article VIII;

          (C) by NBI or BTC, if its Board of Directors so determines by vote of
     a majority of the members of its entire Board, in the event that the Merger
     is not consummated by June 30, 1996, and provided, further, that
     termination under this Paragraph (C) shall not relieve any party from
     liability under Paragraph (E)(2) of Article VIII;

          (D) by NBI or BTC, if its Board of Directors so determines by a vote
     of a majority of the members of its entire Board, in the event that (1) any
     common stockholder approval contemplated by Paragraph (A) of Article VI is
     not obtained at a meeting or meetings called for the purpose of obtaining
     such approval; (2) Interim Approval, FDIC Approval, State Bank Merger
     Approval, FRB Approval, or State Holding Company Approval, to the extent
     necessary to consummate the Merger legally, is finally and unconditionally
     denied; or (3) the Board of Directors of NBI recommends to NBI shareholders
     approval of a sale of all or substantially all of the assets of NBI or the
     merger or consolidation of NBI with and into another entity with the effect
     that NBI will not be the surviving corporation in such merger or
     consolidation; provided, however, that termination under this Paragraph (D)
     shall not relieve any party from liability under Paragraph (E)(2) of
     Article VIII.

                              VIII. OTHER MATTERS.

          (A) Survival.  If the Merger Effective Date occurs, the agreements of
     the parties in Paragraphs (F) and (G) of Article I, Paragraph (E) of
     Article II, Paragraphs (R) and (S) of Article V, and Paragraphs (A), (C),
     (D), (F), (I), (J) and (K) of this Article VIII shall survive the Merger
     Effective Date; all other representations, warranties, agreements and
     covenants contained in this Plan shall be deemed to be conditions of the
     Merger and shall not survive the Merger Effective Date.  If this Plan is
     terminated prior to the Merger Effective Date, the agreements and
     representations of the parties in Paragraph (K) of Article IV, Paragraphs
     (F)(2) and (G) of Article V and Paragraphs (A), (E), (F) and (I) of this
     Article VIII shall survive such termination.  In the event of the
     termination and abandonment of this Plan pursuant to the provisions of
     Article VII, this Plan shall become void and have no effect, except (1) as
     provided in the immediately preceding sentence; and (2) no party shall be
     relieved or released from any liability arising out of a breach of any
     provisions of this Plan except as provided in Paragraph (E)(2) of this
     Article.

          (B) Waiver, Amendment.  Prior to the Merger Effective Date, any
     provision of this Plan may be (1) waived by the party benefitted by the
     provision, or (2) amended or modified at any time (including the structure
     of the transaction), by an agreement in writing among the parties hereto
     approved by their respective Boards of Directors and executed in the same
     manner as this Plan, except that, after the vote by the stockholders of
     BTC, the consideration to be received by the stockholders of BTC for each
     share BTC Common Stock shall not be decreased.

          (C) Counterparts.  This Plan may be executed in one or more
     counterparts, each of which shall be deemed to constitute an original.
     This Plan shall become effective when one counterpart has been signed by
     each party hereto.

                                      A-19
<PAGE>
 
          (D) Governing Law.  This Plan shall be governed by, and interpreted in
     accordance with, the laws of the State of Virginia.

          (E)  Fees and Expenses.

               (1) In the event that the Plan is terminated in accordance with
     the provisions of Article VII otherwise than on account of a breach by NBI
     or in the event it is terminated in accordance with the provisions of
     Paragraph (D)(3) of Article VII, and in either such event the provisions of
     Paragraph (2) of this Paragraph E are not applicable, then the total
     documented out-of-pocket costs, expenses and fees incurred by BTC and NBI
     (regardless of when incurred) in connection with and arising out of the
     Merger and the other transactions contemplated by this Plan (including,
     without limitation, amounts paid or payable to investment bankers, to
     counsel and accountants, and to governmental and regulatory agencies) shall
     be aggregated and each party hereto shall be responsible for paying one-
     half (1/2) of the same, and shall promptly make such reimbursement to the
     other party as is necessary to effectuate this result.

               (2) To compensate NBI or BTC, as the case may be, for entering
     into this Plan, taking action to consummate the transactions contemplated
     hereunder and incurring the costs and expenses related thereto, including
     but not limited to the foregoing of other opportunities and other damages
     which would be sustained but would also be difficult to ascertain in the
     event that any of the following events occur, the subject party (as
     hereinafter defined) agrees to pay the other party (if the "subject party"
     is BTC, then the "other party" shall be NBI and vice versa) unconditionally
                                                     ----------                 
     and absolutely the sum of $2,500,000 as the other party's exclusive remedy
     if, prior to the termination of this Plan pursuant to Article VII hereof,
     any of the following shall occur:

               (a) Without the consent of the other party, the subject party
                   shall have entered into an agreement with any person (other
                   than as contemplated by this Plan) to effect (i) a merger,
                   consolidation or similar transaction involving the subject
                   party or any of its significant subsidiaries, (ii) the
                   disposition, by sale, lease, exchange or otherwise, of assets
                   or deposits of subject party or any of its significant
                   subsidiaries representing in either case 25% or more of the
                   consolidated assets or deposits of the subject party and its
                   subsidiaries or (iii) the issuance, sale or other disposition
                   by the subject party of (including by way of merger,
                   consolidation, share exchange or any similar transaction)
                   securities representing 25% or more of the voting power of
                   the subject party or any of its significant subsidiaries
                   (each of (i), (ii) or (iii), an "Acquisition Transaction");
                   or

               (b) Any person shall have acquired beneficial ownership (as such
                   term is defined in Rule 13d-3 promulgated under the Exchange
                   Act) of, or the right to acquire beneficial ownership of, or
                   any "group" (as such term is defined in Section 13(d)(3) of
                   the Exchange Act) shall have been formed which beneficially
                   owns or has the right to acquire beneficial ownership of, 20%
                   or more of the voting power of the subject party or any of
                   its significant subsidiaries and, within one year from
                                                --- 
                   termination of this Plan the subject party enters into an
                   Acquisition Transaction with such person or group, as the
                   case may be.

               (3) In the event that neither Paragraph (1) nor Paragraph (2) of
     this Paragraph (E) are applicable, each party hereto will bear all expenses
     incurred by it in connection with this Plan and the transactions
     contemplated hereby, except printing expenses which shall be shared equally
     between BTC and NBI.  It is understood and agreed that the printer of the
     Registration Statement and Proxy Statement shall be mutually selected by
     NBI and BTC.

               (4) Payments to be made hereunder shall be made in immediately
     available funds within thirty (30) days following the day on which the
     party entitled to payment notifies the other party in writing that the
     events entitling it to payment of the same have occurred and upon failure
     to pay the same when due the other party shall 

                                      A-20
<PAGE>
 
     be entitled to recover from the other party all collection costs and
     expenses, including but not limited to reasonable legal fees.


          (F) Confidentially.  Except as otherwise provided in Paragraph (F)(2)
     of Article V, each of the parties hereto and their respective agents,

          (H) Definitions.  Any term defined anywhere in this Plan shall have
     the meaning ascribed to it for all purposes of this Plan (unless expressly
     noted to the contrary).  In addition:

                                      A-21
<PAGE>
 
               (1) the term "knowledge" when used with respect to a party shall
     mean the knowledge, after due inquiry, of any "Executive Officer" of such
     party or, in the case of NBI, of NBB, as such term is defined in Regulation
     O of the Federal Reserve Board;

               (2) the term "Material Adverse Effect," when applied to a party,
     shall mean an event, occurrence or circumstance (including without
     limitation (a) the making of any provisions for possible loan and lease
     losses, write-downs of other real estate and taxes and (b) any breach of a
     representation or warranty by such party) which (i) has or is reasonably
     likely to have a material adverse effect on the financial position, results
     of operations or business of the party and its subsidiaries, taken as a
     whole, or (ii) would materially impair the party's ability to perform its
     obligations under this Plan or the consummation of the Merger and the other
     transactions contemplated by this Plan; provided, however, that, solely for
     purposes of measuring whether an event, occurrence or circumstance has a
     material adverse effect on such party's results of operations, the term
     "results of operations" shall mean net interest income plus non-interest
     income (less securities gains) less gross expenses (excluding provisions
     for possible loan and lease losses, write-downs of other real estate and
     taxes); and provided, further, that material adverse effect and material
     impairment shall not be deemed to include the impact of (x) changes in
     banking and similar laws of general applicability or interpretations
     thereof by courts or governmental authorities, (y) changes in generally
     accepted accounting principles or regulatory accounting requirements
     applicable to banks and bank holding companies generally and (z) the
     effects of Merger on the operating performance of the parties to this Plan;

               (3) the term "Previously Disclosed" by a party shall mean
     information set forth in a written disclosure letter that is delivered by
     that party to the other party contemporaneously with the execution of this
     Plan and specifically designated as information "Previously Disclosed"
     pursuant to this Plan; provided, however, that any information so disclosed
     shall specify the provision of this Plan pursuant to which such information
     is being disclosed and shall not be deemed to be disclosed pursuant to any
     other provision of, or for any other purpose under, this Plan unless
     otherwise indicated; provided, further, the mere inclusion of an item in a
                          --------  -------                                    
     disclosure letter shall not be deemed an admission by a party that such
     item represents a material exception of fact, event or circumstances or
     that such item is reasonably likely to result in a Material Adverse Effect.

          (I) Entire Understanding.  This Plan represents the entire
     understanding of the parties hereto with reference to the transactions
     contemplated hereby and supersede any and all other oral or written
     agreements heretofore made, include without limitation the Confidentiality
     Agreement, dated June 16, 1995 between NBI and BTC.  Nothing in this Plan
     expressed or implied, is intended to confer upon any person, other than the
     parties hereto or their respective successors, any rights, remedies,
     obligations or liabilities under or by reason of this Plan, other than as
     provided in Paragraph (K) below.

          (J) Benefit Plans.  It is the parties' intention that upon
     consummation of the Merger, or as soon as administratively practicable
     thereafter, employees of BTC and its subsidiaries shall be entitled to
     participate in NBI's severance, benefit and similar plans (excluding
     qualified retirement plans) on the same terms and conditions as employees
     NBI's and its subsidiaries, giving effect to years of service and prior
     earnings with BTC and its subsidiaries as if such service were with NBI.
     The parties agree to engage experts, including but not limited to
     actuaries, to make recommendations as to how the qualified retirement plans
     should be handled and shall use their best efforts to come to an agreement
     regarding all benefit plans which shall be in the form of an amendment to
     this Agreement.  The parties agree that to the extent possible no employee
     of BTC who elects coverage by NBI's medical insurance plans shall be
     excluded coverage thereunder (for such employee or any other covered
     person) on the basis of a preexisting condition that was not also excluded
     under BTC's medical insurance plans and that, if an NBI plan will not take
     the place of a BTC plan pursuant to this Agreement, then such BTC benefit
     plan shall remain in effect until the benefit plan of NBI is available for
     participation by the officers and employees of BTC.

          (K) Indemnification.  (1) In the case of NBI only, it agrees that for
     the six-year period following the Merger Effective Date, it shall cause the
     Continuing Corporation and any successor thereto or any subsidiary thereof,
     as may be applicable, to indemnify and hold harmless any person who has
     rights to indemnification from BTC to 

                                      A-22
<PAGE>
 
     the same extent and on the same conditions as such person is entitled to
     indemnification pursuant to BTC's Articles of Incorporation as in effect on
     the date of this Plan, to the extent legally permitted to do so, with
     respect to matters occurring on or prior to the Merger Effective Date
     (regardless of whether a claim is asserted in connection therewith on or
     prior to the Merger Effective Date or thereafter) and the adoption of the
     Charter Amendment shall not affect the right, if any, to indemnification of
     any person under this Paragraph (K) with respect to such pre-Merger
     matters. Without limiting the foregoing, in any case in which approval by
     the Continuing Corporation may be required to effectuate any such
     indemnification, NBI shall cause the Continuing Corporation to direct, at
     the election of the party to be indemnified, that the determination of any
     such approval shall be made by independent counsel mutually agreed upon
     between NBI and the indemnified party. NBI shall use its reasonable best
     efforts to provide coverage to the officers and directors of the Continuing
     Corporation under NBI policy or policies of director and officers liability
     insurance on the same or substantially similar terms then in effect for the
     directors and officers of NBB and the Continuing Corporation shall
     reimburse NBI for the additional premium incurred by it in connection with
     providing such coverage.

          If NBI or any of its successors or assigns shall consolidate with or
     merge into any other entity and shall not be the continuing or surviving
     entity of such consolidation or merger or shall transfer all or
     substantially all of its assets to any entity, then and in each case,
     proper provisions shall be made so that the successors and assigns of NBI
     shall assume the obligations set forth in this Paragraph (K)(1).  NBI shall
     pay all reasonable costs, including attorneys' fees, that may be incurred
     by any Indemnified Party in enforcing the indemnity and other obligations
     provided for in this Paragraph (K)(1).

          (2) With respect to matters occurring after the Merger Effective Date,
     the rights, if any, of any person to be held harmless or indemnified shall
     be governed by the Articles of Incorporation and Bylaws of the Continuing
     Corporation as provided in Paragraph (D) of Article I, and by the Articles
     of Incorporation of NBI, to the extent applicable by their terms.

          IN WITNESS WHEREOF, the parties hereto have caused this instrument to
     be executed in counterparts by their duly authorized officers, all as of
     the day and year first above written.

                                 PLAN OF MERGER


               A.  NBI Interim Bank ("NBI Interim Bank") is a corporation
     organized and existing under the laws of the Commonwealth of Virginia and
     is a wholly-owned subsidiary of National Bankshares, Inc., a Virginia
     corporation ("NBI").

               B.  Bank of Tazewell County ("BTC") is a banking corporation
     organized and existing under the laws of the Commonwealth of Virginia.

               C.  The NBI Interim Bank and BTC and their respective Boards of
     Directors and their respective shareholders have approved a statutory
     merger of NBI Interim Bank with and into BTC upon the terms and conditions
     set forth herein.

               1.  Merger.  At the Effective Time (as defined below), NBI
                   ------                                                
     Interim Bank shall be merged with and into BTC (the "Merger") in accordance
     with the provisions of Article 12 of the Virginia Stock Corporation Act and
     Article 4 of the Virginia Banking Act.  BTC shall be and continue in
     existence as the surviving corporation (the "Continuing Corporation") and
     the separate corporate existence of NBI Interim Bank shall cease.

               2.  Effective Time.  The Merger shall become effective at the
                   --------------                                           
     time when a certificate of merger in respect thereof shall have been issued
     by the State Corporation Commission of the Commonwealth of Virginia (the
     "Effective Time") but in no event before the conditions in Article VI of
     the Agreement and Plan of Merger between NBI and BTC dated as of August 28,
     1995 (the "Agreement") shall have been fulfilled or waived.

               3.  Effect of Merger on Outstanding Shares.  As of the Effective
                   --------------------------------------                      
     Time, by virtue of the Merger and without any action on the part of the
     holder of any share of common stock, $1.00 par value of BTC (each, a "BTC
     Share") or the holder of any share of the common stock $1.00 par value of
     NBI Interim Bank (a "Interim Bank Share"):

                   (a) The shareholders of BTC having eliminated preemptive
                       rights pursuant to an amendment to the BTC Articles of
                       Incorporation which shall be effective as of the
                       Effective Time, each issued and outstanding Interim Bank
                       Share shall be converted into 1,888,209 shares of common
                       stock of the Continuing Bank and shall constitute the
                       only issued and outstanding shares of common stock of the
                       Continuing Bank.

                   (b) Each outstanding BTC Share (other than any share as to
                       which dissenters' rights are exercised) shall be
                       converted into the right to receive one share of common
                       stock, $2.50 par value, of NBI ("NBI Shares") it being
                       understood that such conversion takes into account the
                       190,768 share stock dividend declared by NBI's Board of
                       Directors and payable to shareholders of record before
                       the Merger Effective Date, as provided in the Agreement.

                   (c) The number of NBI Shares to be received pursuant to this
                       Section 3 by each holder of BTC Shares at the Effective
                       Time shall be proportionately adjusted for any increase
                       or decrease (exclusive of the stock dividend referred to
                       in Section 3(b)) in the number of issued NBI Shares from
                       the date of this Agreement to the Effective Time
                       resulting from a subdivision or consolidation of shares
                       or the payment of a share dividend or any other increase
                       or decrease in the number of NBI Shares effective without
                       receipt of "adequate consideration" as defined under
                       applicable Virginia law.

                   (d) From and after the Effective Time the holders of
                       certificates formerly representing BTC Shares shall cease
                       to have any rights with respect thereto other than any
                       dissenters' rights and their sole right shall be to
                       receive NBI Shares and cash pursuant to Sections 3(b) and
                       3(e). After the Effective Time, there shall be no
                       transfers on the stock transfer books of BTC or
                       Continuing Corporation of the shares of BTC which were
                       issued and outstanding immediately prior to the Effective
                       Time.

                   (e) Fractional Shares. Notwithstanding any other provision
                       hereof, no fractional shares of NBI Shares and no
                       certificates or scrip therefor, or other evidence of
                       ownership thereof, will be issued in the Merger; instead,
                       NBI shall pay to each holder of BTC Shares who would
                       otherwise be entitled to a fractional share an amount in
                       cash determined by multiplying such fractional shares by
                       the closing sale price of BTC Shares for the final bona
                       fide trade on the last day on which such stock was traded
                       prior to the Merger Effective Date, as reflected in the
                       Over the Counter Electronic Bulletin Board of the
                       National Association of Securities Dealers, Inc.

                   (f) Dissenting Shareholders. Any holder of BTC Shares who
                       perfects his dissenters' rights of appraisal in
                       accordance with and as contemplated by Article 15 of the
                       Virginia Stock Corporation Act shall be entitled to
                       receive the value of such shares in cash as determined
                       pursuant to such provision of law; provided, however,
                       that no such payment shall be made to any dissenting
                       stockholder unless and until such dissenting stockholder
                       has complied with the applicable provisions of the
                       Virginia Stock Corporation Act and duly surrendered the
                       certificate or certificates representing the shares for
                       which payment is made. In the event that a dissenting
                       stockholder of BTC fails to perfect, or effectively
                       withdraws or loses, his right to appraisal and of payment
                       for his shares, after the Effective Time NBI shall issue
                       and deliver the consideration to which such holder of BTC
                       Shares is entitled under this Plan of Merger (without
                       interest) upon surrender by such holder of the
                       certificate or certificates representing the BTC Shares
                       held by him.

                   (g) Exchange Procedures. As promptly as practicable after the
                       Effective Time, NBI shall send or cause to be sent to
                       each former stockholder of BTC of record immediately
                       prior to the Effective Time transmittal materials for use
                       in exchanging such stockholder's certificates of BTC
                       Shares (other than shares held by stockholders who
                       perfect their dissenters' rights as provided under
                       Paragraph (f) above) for the consideration set forth in
                       Paragraphs (b) and (e) above. Any fractional share checks
                       which a BTC stockholder shall be entitled to receive in
                       exchange for such stockholder's BTC Shares, and any
                       dividends paid on any shares of NBI Shares, that such
                       stockholder shall be entitled to receive prior to the
                       delivery to NBI of such stockholder's certificates
                       representing all of such stockholder's BTC Shares will be
                       delivered to such stockholder only upon delivery to NBI
                       of the certificates representing all of such shares (or
                       indemnity satisfactory to NBI, in its judgment after
                       consultation with the President of BTC, if any of such
                       certificates are lost, stolen or destroyed). No interest
                       will be paid on any such fractional share checks or
                       dividends to which the holder of such shares shall be
                       entitled to receive upon such delivery. After the
                       Effective Time, to the extent permitted by law, former
                       stockholders of record of BTC shall be entitled to vote
                       at any meeting of holders of NBI Shares, the number of
                       whole shares of NBI Shares into which their respective
                       BTC shares are converted, regardless of whether such
                       holders have exchanged their certificates representing
                       BTC Shares for certificates representing NBI Shares in
                       accordance with the provisions of this Plan of Merger.
 
                   (h) Anti-Dilution Provisions. In the event NBI changes the
                       number of shares of NBI Shares issued and outstanding
                       prior to the Effective Time as a result of a stock split,
                       share

                       3(b) above), recapitalization or similar transaction with
                       respect to the outstanding NBI Shares and the record date
                       therefor shall be prior to the Effective Time, the
                       Exchange Ratio shall be proportionately adjusted.

                   (i) Shares Held by BTC or NBI. Each of the BTC Shares held by
                       BTC or by NBI or its subsidiary, in each case other than
                       in a fiduciary capacity or as a result of debts
                       previously contracted, shall be canceled and retired at
                       the effectiveness of the Merger and no consideration
                       shall be issued in exchange therefor.

               4.  Articles of Incorporation and Bylaws.  Taking into effect the
     amendments thereto required to be made by the Agreement, the Articles of
     Incorporation and Bylaws of BTC in effect at the Effective Time shall
     continue (until amended or repealed as provided by applicable law) to be
     the Articles of Incorporation and Bylaws of the Continuing Corporation
     after the Effective Time.

               5.  Officers and Directors.  The officers and directors of BTC
     immediately prior to the Effective Time shall be the officers and directors
     of the Continuing Corporation after the Effective Time to serve, in
     accordance with the Bylaws of the Continuing Corporation, until their
     successors are duly elected and qualified, or their earlier death,
     resignation or removal.

               6.  Termination of Abandonment.  This Plan of Merger shall
     terminate and the Merger abandoned at any time prior to the Effective Time
     if the Agreement is terminated in accordance with its terms.

               7.  Amendment.  Pursuant to Section 13.1-718(I) of the Virginia
     Stock Corporation Act, the Board of Directors of BTC and NBI Interim Bank
     reserve the right to amend this Plan of Merger at any time prior to
     issuance of the certificate of merger by the State Corporation Commission
     of the Commonwealth of Virginia; provided, however, that any such amendment
     made subsequent to the submission of this Plan of Merger to the
     shareholders of BTC or NBI Interim Bank may not:  (i) alter or change the
     amount or kind of shares, securities, cash, property or rights to be
     received in exchange for or in conversion of all or any of the shares of
     any class or series of such corporation; (ii) alter or change any of the
     terms and conditions of this Plan of Merger if such alteration or change
     would adversely affect the shares of any class or series of such
     corporation; or (iii) alter or change any term of the articles of
     incorporation of any corporation (except as provided herein) whose
     shareholders must approve this Plan of Merger.

          Amendment No. 3 - Indemnification of Directors and Officers


               RESOLVED, that the Articles of Incorporation of Bank of Tazewell
     County shall be amended so that the provisions approved by the shareholders
     on March 17, 1992, regarding indemnification and the limitation of
     liability of directors, officers and certain other persons shall be amended
     in their entirety to read as follows:

               "(1)  In this Article:

                     "applicant" means the person seeking indemnification
     pursuant to this Article.

                     "expenses" includes counsel fees.

                     "liability" means the obligation to pay a judgment,
     settlement, penalty, fine, including any excise tax assessed with respect
     to an employee benefit plan, or reasonable expenses incurred with respect
     to a proceeding.

                     "party" includes an individual who was, is, or is
     threatened to be made a named defendant or respondent in a proceeding.

                                      B-1
<PAGE>
 
                     "proceeding" means any threatened, pending, or completed
     action, suit, or proceeding, whether civil, criminal, administrative or
     investigative and whether formal or informal.

               (2) The Bank shall, to the extent permitted by the applicable
     banking laws, indemnify (i) any person who was or is a party to any
     proceeding, including a proceeding brought by a shareholder in the right of
     the Bank or brought by or on behalf of shareholders of the Bank, by reason
     of the fact that he or she is or was a director or officer of the Bank, or
     (ii) any director or officer who is or was serving at the request of the
     Bank as a director, trustee, partner or officer of another corporation,
     partnership, joint venture, trust, employee benefit plan or other
     enterprise, against any liability incurred by him or her in connection with
     such proceeding unless he or she engaged in willful misconduct or a knowing
     violation of criminal law.  A person is considered to be serving an
     employee benefit plan at the Bank's request if his duties to the Bank also
     impose duties on, or otherwise involve services by, him to the plan or to
     participants in or beneficiaries of the plan.  The Board of Directors is
     hereby empowered by a majority vote of a quorum of disinterested Directors,
     to enter into a contract to indemnify any director or officer in respect of
     any proceedings arising from any act or omission, whether occurring before
     or after the execution of such contract.

               (3) No amendment or repeal of this Article shall have any effect
     on the rights provided under this Article with respect to any act or
     omission occurring prior to such amendment or repeal.  The Bank shall
     promptly take all such actions, and make all such determinations, as shall
     be necessary or appropriate to comply with its obligation to make any
     indemnity under this Article and shall promptly pay or reimburse all
     reasonable expenses including attorneys' fees, incurred by any such
     director or officer in connection with such actions and determinations or
     proceedings of any kind arising therefrom.

               (4) The termination of any proceeding by judgment, order,
     settlement, conviction, or upon a plea of nolo contendere or its
     equivalent, shall not of itself create a presumption that the applicant did
     not meet the standard of conduct described in Section (2) of this Article.

               (5) Any indemnification under section (2) of this Article (unless
     ordered by a court) shall be made by the Bank only as authorized in the
     specific case upon a determination that indemnification of the applicant is
     proper in the circumstances because he or she has met the applicable
     standard of conduct set forth in section (2).

               The determination shall be made:

                    (a) By the Board of Directors by a majority vote of a quorum
     consisting of Directors not at the time parties to the proceeding;

                    (b) If a quorum cannot be obtained under subsection (a) of
     this section, by a majority vote of a committee duly designated by the
     Board of Directors (in which designation Directors who are parties may
     participate), consisting solely of two or more Directors not at the time
     parties to the proceeding;

                    (c)  By special legal counsel;

                         (i)  Selected by the Board of Directors or its
     committee in the manner prescribed in subsection (a) or (b) of this
     section; or

                         (ii)  If a quorum of the Board of Directors cannot be
     obtained under subsection (a) of this section and a committee cannot be
     designated under subsection (b) of this section, selected by majority vote
     of the full Board of Directors, in which selection Directors who are
     parties may participate; or

                    (d) By the shareholders, but shares owned by or voted under
     the control of Directors who are at the time parties to the proceeding may
     not be voted on the determination.

                                      B-2
<PAGE>
 
               Any evaluation as to reasonableness of expenses shall be made in
     the same manner as the determination that indemnification is appropriate,
     except that if the determination is made by special legal counsel, such
     evaluation as to reasonableness of expenses shall be made by those entitled
     under subsection (c) of this section (5) to select counsel.

               Notwithstanding the foregoing, in the event there has been a
     change in the composition of a majority of the Board of Directors after the
     date of the alleged act or omission with respect to which indemnification
     is claimed, any determination as to indemnification and advancement of
     expenses with respect to any claim for indemnification made pursuant to
     this Article shall be made by special legal counsel agreed upon by the
     Board of Directors and the applicant.  If the Board of Directors and the
     applicant are unable to agree upon such special legal counsel the Board of
     Directors and the applicant each shall select a nominee, and the nominees
     shall select such special legal counsel.

               (6) (a) To the extent permitted by applicable banking laws and
     regulations, the Bank shall pay for or reimburse the reasonable expenses
     incurred by any applicant who is a party to a proceeding in advance of
     final disposition of the proceeding or the making of any determination
     under section (5) if the following conditions are met:

                    (i)  The Board, in good faith, determines in writing that:

                         (A) the director has a substantial likelihood of
     prevailing on the merits:

                         (B) in the event the director does not prevail, he or
     she will have the financial capability to reimburse the Bank; and

                         (C) payment of expenses by the Bank will not adversely
     affect the Bank's safety and soundness.

                    To the extent required by applicable banking laws and
     regulations, if at any time the Board believes that either conditions (A),
     (B) or (C) are no longer met, the Bank shall cease paying such expenses or
     premiums. The Board shall enter into a written agreement with the director,
     specifying the conditions under which he or she will be required to
     reimburse the Bank, which agreement shall require reimbursement for
     expenses already paid, if and to the extent the Board finds that the
     director willfully misrepresented factors relevant to the Board's
     determination of conditions (A) or (B), or if a final decision assessing
     penalties or requiring payments is returned. The Bank shall ensure that it
     complies with all applicable laws and regulations affecting loans to
     directors, officers and employees, in the event reimbursement is required.

                    (ii) Additionally, the applicant must furnish the Bank:

                         (A) a written statement of his good faith belief that
     he or she has met the standard of conduct described in section (2); and

                         (B) a written undertaking, executed personally or on
     his or her behalf to repay the advance if it is ultimately determined that
     he or she did not meet such standard of conduct.

                    (b)  Authorizations of payments under this section shall be
     made by the persons specified in section (5).

               (7)  The Board of Directors is hereby empowered, by majority vote
     of a quorum consisting of disinterested Directors, to cause the Bank to
     indemnify or contract to indemnify any person not specified in section (2)
     of this Article who was, is or may become a party to any proceeding by
     reason of the fact that he or she is or was an  employee or agent of the
     Bank, or is or was serving at the request of the Bank as director, officer,
     employee or agent of another corporation, partnership, joint venture,
     trust, employee benefit plan or other enterprise, to the 

                                      B-3
<PAGE>
 
     same extent as if such person were specified as one to whom indemnification
     is granted in section (2). The provisions of sections (3) through (6) and
     (11) of this Article shall be applicable to any indemnification provided
     hereafter pursuant to this section (7).

               (8) The Bank may purchase and maintain insurance to indemnify it
     against the whole or any portion of the liability assumed by it in
     accordance with this Article and may also procure insurance, in such
     amounts as the Board of Directors may determine, on behalf of any person
     who is or was a director, officer, employee or agent of the Bank, or is or
     was serving at the request of the Bank as a director, officer, employee or
     agent of another corporation, partnership joint venture, trust, employee
     benefit plan or other enterprise, against any liability asserted against or
     incurred by him or her in any such capacity or arising from his status as
     such, whether or not the Bank would have power to indemnify him against
     such liability under the provisions of this Article.

               (9) Every reference herein to directors, officers, employees or
     agents shall include former directors, officers, employees and agents and
     their respective heirs, executors and administrators.

               (10) Each provision of this Article shall be severable, and an
     adverse determination as to any such provision shall in no way affect the
     validity of any other provision.

               (11) The provisions of this Article and of any contracts or
     agreements (other than insurance acquired pursuant to Section (8)) entered
     into pursuant to it shall apply only to conduct, actions and omissions of
     any applicant occurring or arising after the date and time these Articles
     are made effective by the State Corporation Commission of Virginia and the
     merger of NBI Interim and the Bank of Tazewell County is made effective by
     the issuance of a certificate of the Virginia State Corporation
     Commission."


                          Amendment No. 4 - Deletions

               RESOLVED, that the Articles of Incorporation of Bank of Tazewell
     County shall be amended by deleting the following: (i) the provision
     approved by the shareholders on April 15, 1964, stating that the Board of
     Directors shall have the right to sell 25% of the remaining authorized and
     unissued shares, as to which shares shareholders will not have preemptive
     rights; (ii) the provision approved by the shareholders on March 17, 1992,
     stating that the Board of Directors may sell up to 10,000 shares of
     authorized stock, as to which shares shareholders will not have preemptive
     rights; (iii) any and all other provisions inconsistent with the
     elimination of preemptive rights of shareholders with respect to securities
     of the Bank; and (iv) any and all other provisions inconsistent with the
     amendment of the indemnification and limitation of liability of directors,
     officers and certain other persons set out in Amendment No. 3 above.

                            [Date of Proxy Mailing]


     The Board of Directors
     Bank of Tazewell County
     309 E. Main Street
     Tazewell, Virginia 24651

     Dear Members of the Board:

     Bank of Tazewell County, Tazewell, Virginia ("Tazewell") and National
     Bankshares, Inc., Blacksburg, Virginia ("National") have entered into an
     Agreement providing for the acquisition of Tazewell by National
     ("Acquisition").  The terms of the Acquisition are set forth in the
     Agreement and Plan of Merger dated August 28, 1995.

     The terms of the Acquisition provide that, with the possible exception of
     those shares as to which dissenter's rights may be perfected, each common
     share of Tazewell will be converted into shares of common stock of
     National.

     You have asked our opinion as to whether the proposed transaction pursuant
     to the terms of the Acquisition are fair to the respective shareholders of
     Tazewell from a financial point of view.

     In rendering our opinion, we have evaluated the consolidated financial
     statements of Tazewell available to us from published sources.  In
     addition, we have, among other things:  (a) to the extent deemed relevant,
     analyzed selected public information of certain other financial
     institutions and compared Tazewell and National from a financial point of
     view to the other financial institutions; (b) considered the historical
     market price of the common stock of Tazewell and National; (c) compared the
     terms of the Acquisition with the terms of certain other comparable
     transactions to the extent information concerning such acquisitions was
     publicly available; (d) reviewed the Agreement and Plan of Merger and
     related documents; and (e) made such other analyses and examinations as we
     deemed necessary.  We also met with various senior officers of Tazewell and
     National to discuss the foregoing as well as other matters that may be
     relevant.

     We have not independently verified the financial and other information
     concerning Tazewell, or National or other data which we have considered in
     our review.  We have assumed the accuracy and completeness of all such
     information; however, we have no reason to believe that such information is
     not accurate and complete.  Our conclusion is rendered on the basis of
     securities market conditions prevailing as of the date hereof and on the
     conditions and prospects, financial and otherwise, of Tazewell and National
     as they exist and are known to us as of September 30, 1995.

     It is understood that this opinion may be included in its entirety in any
     communication by Tazewell or the Board of Directors to the stockholders of
     Tazewell.  The opinion may not, however, be summarized, excerpted from or
     otherwise publicly referred to without our prior written consent.

     Based on the foregoing, and subject to the limitations described above, we
     are of the opinion that the terms of the Acquisition are fair to the
     shareholders of Tazewell from a financial point of view.

     Very truly yours,

                                                                    ATTACHMENT D

                ARTICLE 15 OF THE VIRGINIA STOCK CORPORATION ACT
                         RELATING TO DISSENTERS' RIGHTS


          (S) 13.1-729.     DEFINITIONS. - In this article:
          "Corporation" means the issuer of the shares held by a dissenter
     before the corporate action, except that (i) with respect to a merger,
     "corporation" means the surviving domestic or foreign corporation or
     limited liability company by merger of that issuer, and (ii) with respect
     to a share exchange, "corporation" means the acquiring corporation by share
     exchange, rather than the issuer, if the plan of share exchange places the
     responsibility for dissenters' rights on the acquiring corporation.

          "Dissenter" means a shareholder who is entitled to dissent from
     corporate action under (S) 13.1-730 and who exercises that right when and
     in the manner required by (S)(S) 13.1-732 through 13.1-739.

          "Fair value," with respect to a dissenter's shares, means the value of
     the shares immediately before the effectuation of the corporate action to
     which the dissenter objects, excluding any appreciation or depreciation in
     anticipation of the corporate action unless exclusion would be inequitable.

          "Interest" means interest from the effective date of the corporate
     action until the date of payment, at the average rate currently paid by the
     corporation on its principal bank loans or, if none, at a rate that is fair
     and equitable under all the circumstances.

          "Record shareholder" means the person in whose name shares are
     registered in the records of a corporation or the beneficial owner of
     shares to the extent of the rights granted by a nominee certificate on file
     with a corporation.

          "Beneficial shareholder" means the person who is a beneficial owner of
     shares held by a nominee as the record shareholder.

          "Shareholder" means the record shareholder or the beneficial
     shareholder.

          (S) 13.1-730.  RIGHT TO DISSENT. - A.  A shareholder is entitled to
     dissent from, and obtain payment of the fair value of his shares in the
     event of, any of the following corporate actions:

          1.  Consummation of a plan of merger to which the corporation is a
     party (i) if shareholder approval is required for the merger by (S) 13.1-
     718 or the articles of incorporation and the shareholder is entitled to
     vote on the merger or (ii) if the corporation is a subsidiary that is
     merged with its parent under (S) 13.1-719;

          2.  Consummation of a plan of share exchange to which the corporation
     is a party as the corporation whose shares will be acquired, if the
     shareholder is entitled to vote on the plan;

          3.  Consummation of a sale or exchange of all, or substantially all,
     of the property of the corporation if the shareholder was entitled to vote
     on the sale or exchange or if the sale or exchange was in furtherance of a
     dissolution on which the shareholder was entitled to vote, provided that
     such dissenter's rights shall not apply in the case of (i) a sale or
     exchange pursuant to court order, or (ii) a sale for cash pursuant to a
     plan by which all or substantially all of the net proceeds of the sale will
     be distributed to the shareholders within one year after the date of sale;

          4.  Any corporate action taken pursuant to a shareholder vote to the
     extent the articles of incorporation, bylaws, or a resolution of the board
     of directors provides that voting or nonvoting shareholders are entitled to
     dissent and obtain payment for their shares.

          B.  A shareholder entitled to dissent and obtain payment for his
     shares under this article may not challenge the corporate action creating
     his entitlement unless the action is unlawful or fraudulent with respect to
     the shareholder or the corporation.

          C.  Notwithstanding any other provision of this article, with respect
     to a plan of merger or share exchange or a sale or exchange of property
     there shall be no right of dissent in favor of holders of shares of any
     class or series which, at the record date fixed to determine the
     shareholders entitled to receive notice of and to vote at the meeting at
     which the plan of merger or share exchange or the sale or exchange of
     property is to be acted on, were (i) listed on a national securities
     exchange or (ii) held by at least 2,000 record shareholders, unless in
     either case:

          1.  The articles of incorporation of the corporation issuing such
     shares provide otherwise;

                                      D-1
<PAGE>
 
          2.  In the case of a plan of merger or share exchange, the holders of
     the class or series are required under the plan of merger or share exchange
     to accept for such shares anything except:
          a.  Cash;
          b.  Shares or membership interests, or shares or membership interests
     and cash in lieu of fractional shares (i) of the surviving or acquiring
     corporation or limited liability company or (ii) of any other corporation
     or limited liability company which, at the record date fixed to determine
     the shareholders entitled to receive notice of and to vote at the meeting
     at which the plan of merger or share exchange is to be acted on, were
     either listed subject to notice of issuance on a national securities
     exchange or held of record by at least 2,000 record shareholders or
     members; or
          c.  A combination of cash and shares or membership interests as set
     forth in subdivisions 2a and 2b of this subsection; or
          3.  The transaction to be voted on is an "affiliated transaction" and
     is not approved by a majority of "disinterested directors" as such terms
     are defined in (S) 13.1-725.
          D.  The right of a dissenting shareholder to obtain payment of the
     fair value of his shares shall terminate upon the occurrence of any one of
     the following events:
          1.  The proposed corporate action is abandoned or rescinded;
          2.  A court having jurisdiction permanently enjoins or sets aside the
     corporate action; or
          3.  His demand for payment is withdrawn with the written consent of
     the corporation.

          (S) 13.1-731.  DISSENT BY NOMINEES AND BENEFICIAL OWNERS. -  A.  A
     record shareholder may assert dissenters' rights as to fewer than all the
     shares registered in his name only if he dissents with respect to all
     shares beneficially owned by any one person and notifies the corporation in
     writing of the name and address of each person on whose behalf he asserts
     dissenters' rights.  The rights of a partial dissenter under this
     subsection are determined as if the shares as to which he dissents and his
     other shares were registered in the names of different shareholders.
          B.  A beneficial shareholder may assert dissenters' rights as to
     shares held on his behalf only if:
          1.  He submits to the corporation the record shareholder's written
     consent to the dissent not later than the time the beneficial shareholder
     asserts dissenters' rights; and
          2.  He does so with respect to all shares of which he is the
     beneficial shareholder or over which he has power to direct the vote.

          (S) 13.1-732.  NOTICE OF DISSENTERS' RIGHTS. - A.  If proposed
     corporate action creating dissenters' rights under (S) 13.1-730 is
     submitted to a vote at a shareholders' meeting, the meeting notice shall
     state that shareholders are or may be entitled to assert dissenters' rights
     under this article and be accompanied by a copy of this article.
          B.  If corporate action creating dissenters' rights under (S) 13.1-730
     is taken without a vote of shareholders, the corporation, during the ten-
     day period after the effectuation of such corporate action, shall notify in
     writing all record shareholders entitled to assert dissenters' rights that
     the action was taken and send them the dissenters' notice described in (S)
     13.1-734.

          (S) 13.1-733.  NOTICE OF INTENT TO DEMAND PAYMENT. - A.  If proposed
     corporate action creating dissenters' rights under (S) 13.1-730 is
     submitted to a vote at a shareholders' meeting, a shareholder who wishes to
     assert dissenters' rights (i) shall deliver to the corporation before the
     vote is taken written notice of his intent to demand payment for his shares
     if the proposed action is effectuated and (ii) shall not vote such shares
     in favor of the proposed action.
          B.  A shareholder who does not satisfy the requirements of subsection
     A of this section is not entitled to payment for his shares under this
     article.

          (S) 13.1-734.  DISSENTERS' NOTICE. - A.  If proposed corporate action
     creating dissenters' rights under (S) 13.1-730 is authorized at a
     shareholders' meeting, the corporation, during the ten-day period after the
     effectuation of such corporate action, shall deliver a dissenters' notice
     in writing to all shareholders who satisfied the requirements of (S) 13.1-
     733.

          B.  The dissenters' notice shall:
          1.  State where the payment demand shall be sent and where and when
     certificates for certificated shares shall be deposited;
          2.  Inform holders of uncertificated shares to what extent transfer of
     the shares will be restricted after the payment demand is received;
          3.  Supply a form for demanding payment that includes the date of the
     first announcement to news media or to shareholders of the terms of the
     proposed corporate action and requires that the person asserting
     dissenters' rights certify whether or not he acquired beneficial ownership
     of the shares before or after that date;
          4.  Set a date by which the corporation must receive the payment
     demand, which date may not be fewer than thirty nor more than sixty days
     after the date of delivery of the dissenters' notice; and
          5.  Be accompanied by a copy of this article.

          (S) 13.1-735.  DUTY TO DEMAND PAYMENT. - A.  A shareholder sent a
     dissenters' notice described in (S) 13.1-734 shall demand payment, certify
     that he acquired beneficial ownership of the shares before or after the
     date required to be set forth in the dissenters' notice pursuant to
     subdivision 3 of subsection B of (S) 13.1-734, and, in the case of
     certificated shares, deposit his certificates in accordance with the terms
     of the notice.
          B.  The shareholder who deposits his shares pursuant to subsection A
     of this section retains all other rights of a shareholder except to the
     extent that these rights are canceled or modified by the taking of the
     proposed corporate action.
          C.  A shareholder who does not demand payment and deposits his share
     certificates where required, each by the date set in the dissenters'
     notice, is not entitled to payment for his shares under this article.

          (S) 13.1-736.  SHARE RESTRICTIONS. - A.  The corporation may restrict
     the transfer of uncertificated shares from the date the demand for their
     payment is received.
          B.  The person for whom dissenters' rights are asserted as to
     uncertificated shares retains all other rights of a shareholder except to
     the extent that these rights are canceled or modified by the taking of the
     proposed corporate action.

          (S) 13.1-737.  PAYMENT. - A.  Except as provided in (S) 13.1-738,
     within thirty days after receipt of a payment demand made pursuant to 
     (S) 13.1-735, the corporation shall pay the dissenter the amount the
     corporation estimates to be the fair value of his shares, plus accrued
     interest. The obligation of the corporation under this paragraph may be
     enforced (i) by the circuit court in the city or county where the
     corporation's principal office is located, or, if none in this
     Commonwealth, where its registered office is located or (ii) at the
     election of any dissenter residing or having its principal office in the
     Commonwealth, by the circuit court in the city or county where the
     dissenter resides or has its principal office. The court shall dispose of
     the complaint on an expedited basis.
          B.  The payment shall be accompanied by:
          1.  The corporation's balance sheet as of the end of a fiscal year
     ending not more than sixteen months before the effective date of the
     corporate action creating dissenters' rights, an income statement for that
     year, a statement of changes in shareholders' equity for that year, and the
     latest available interim financial statements, if any;
          2.  An explanation of how the corporation estimated the fair value of
     the shares and of how the interest was calculated;
          3.  A statement of the dissenters' right to demand payment under
     (S) 13.1-739; and
          4.  A copy of this article.

          (S) 13.1-738.  AFTER-ACQUIRED SHARES. - A.  A corporation may elect to
     withhold payment required by (S) 13.1-737 from a dissenter unless he was
     the beneficial owner of the shares on the date of the first publication by
     news media or the first announcement to shareholders generally, whichever
     is earlier, of the terms of the proposed corporate action, as set forth in
     the dissenters' notice.
          B.  To the extent the corporation elects to withhold payment under
     subsection A of this section, after taking the proposed corporate action,
     it shall estimate the fair value of the shares, plus accrued interest, and
     shall offer to pay this amount to each dissenter who agrees to accept it in
     full satisfaction of his demand.  The corporation 

                                      D-3
<PAGE>
 
     shall send with its offer an explanation of how it estimated the fair value
     of the shares and of how the interest was calculated, and a statement of
     the dissenter's right to demand payment under (S) 13.1-739.

          (S) 13.1-739.  PROCEDURE IF SHAREHOLDER DISSATISFIED WITH PAYMENT OR
     OFFER.-  A.  A dissenter may notify the corporation in writing of his own
     estimate of the fair value of his shares and amount of interest due, and
     demand payment of his estimate (less any payment under (S) 13.1-737), or
     reject the corporation's offer under (S) 13.1-738 and demand payment of the
     fair value of his shares and interest due, if the dissenter believes that
     the amount paid under (S) 13.1-737 or offered under (S) 13.1-738 is less
     than the fair value of his shares or that the interest due is incorrectly
     calculated.
          B.  A dissenter waives his right to demand payment under this section
     unless he notifies the corporation of his demand in writing under
     subsection A of this section within thirty days after the corporation made
     or offered payment for his shares.

          (S) 13.1-740.  COURT ACTION. - A.  If a demand for payment under 
     (S) 13.1-739 remains unsettled, the corporation shall commence a proceeding
     within sixty days after receiving the payment demand and petition the
     circuit court in the city or county described in subsection B of this
     section to determine the fair value of the shares and accrued interest. If
     the corporation does not commence the proceeding within the sixty-day
     period, it shall pay each dissenter whose demand remains unsettled the
     amount demanded.
          B.  The corporation shall commence the proceeding in the city or
     county where its principal office is located, or, if none in this
     Commonwealth, where its registered office is located.  If the corporation
     is a foreign corporation without a registered office in this Commonwealth,
     it shall commence the proceeding in the city or county in this Commonwealth
     where the registered office of the domestic corporation merged with or
     whose shares were acquired by the foreign corporation was located.
          C.  The corporation shall make all dissenters, whether or not
     residents of this Commonwealth, whose demands remain unsettled parties to
     the proceeding as in an action against their shares and all parties shall
     be served with a copy of the petition.  Nonresidents may be served by
     registered or certified mail or by publication as provided by law.
          D.  The corporation may join as a party to the proceeding any
     shareholder who claims to be a dissenter but who has not, in the opinion of
     the corporation, complied with the provisions of this article.  If the
     court determines that such shareholder has not complied with the provisions
     of this article, he shall be dismissed as a party.
          E.  The jurisdiction of the court in which the proceeding is commenced
     under subsection B of this section is plenary and exclusive.  The court may
     appoint one or more persons as appraisers to receive evidence and recommend
     a decision on the question of fair value.  The appraisers have the powers
     described in the order appointing them, or in any amendment to it.  The
     dissenters are entitled to the same discovery rights as parties in other
     civil proceedings.
          F.  Each dissenter made a party to the proceeding is entitled to
     judgment (i) for the amount, if any, by which the court finds the fair
     value of his shares, plus interest, exceeds the amount paid by the
     corporation or (ii) for the fair value, plus accrued interest, of his
     after-acquired shares for which the corporation elected to withhold payment
     under (S) 13.1-738.

          (S) 13.1-741.  COURT COSTS AND COUNSEL FEES. - A.  The court in an
     appraisal proceeding commenced under (S) 13.1-740 shall determine all costs
     of the proceeding, including the reasonable compensation and expenses of
     appraisers appointed by the court.  The court shall assess the costs
     against the corporation, except that the court may assess costs against all
     or some of the dissenters, in amounts the court finds equitable, to the
     extent the court finds the dissenters did not act in good faith in
     demanding payment under (S) 13.1-739.
          B.  The court may also assess the reasonable fees and expenses of
     experts, excluding those of counsel, for the respective parties, in amounts
     the court finds equitable:
          1.  Against the corporation and in favor of any or all dissenters if
     the court finds the corporation did not substantially comply with the
     requirements of (S)(S) 13.1-732 through 13.1-739; or
          2.  Against either the corporation or a dissenter, in favor of any
     other party, if the court finds that the party against whom the fees and
     expenses are assessed did not act in good faith with respect to the rights
     provided by this article.

                                      D-4
<PAGE>
 
          C.  If the court finds that the services of counsel for any dissenter
     were of substantial benefit to other dissenters similarly situated, the
     court may award to these counsel reasonable fees to be paid out of the
     amounts awarded the dissenters who were benefitted.
          D.  In a proceeding commenced under subsection A of (S) 13.1-737 the
     court shall assess the costs against the corporation, except that the court
     may assess costs against all or some of the dissenters who are parties to
     the proceeding, in amounts the court finds equitable, to the extent the
     court finds that such parties did not act in good faith in instituting the
     proceeding.

                PART II. INFORMATION NOT REQUIRED IN PROSPECTUS


     Item 20.  Indemnification of Officers and Directors
     -------   -----------------------------------------

          Section 13.1-692.1 of the Virginia Act places a limitation on the
     liability of officers and directors of a corporation in any proceeding
     brought by or in the right of the corporation or brought by or on behalf of
     stockholders of the corporation.  The damages asserted against an officer
     or director arising out of a single transaction, occurrence, or course of
     conduct shall not exceed the greater of $100,000 or the amount of cash
     compensation received by the officer or director from the corporation
     during the 12 months immediately preceding the act or omission for which
     liability was imposed.  The statute also authorizes the corporation, in its
     articles of incorporation or, if approved by the stockholders, in its
     bylaws, to provide for a different specific monetary limit on, or to
     eliminate entirely, liability.  The liability of an officer or director
     shall not be limited or eliminated if the officer or director engaged in
     willful misconduct or a knowing violation of the criminal law or any
     federal or state securities law.  NBI's Articles of Incorporation contain a
     provision which eliminates, to the full extent that the laws of the
     Commonwealth of Virginia permit, the liability of an officer or director to
     NBI or its stockholders for monetary damages for any breach of duty as a
     director or officer.

          NBI's Articles of Incorporation also require NBI to indemnify any
     director or officer who is or was a party to a proceeding, including a
     proceeding by or in the right of the corporation, by reason of the fact
     that he is or was such a director or officer or is or was serving at the
     request of NBI as a director, officer, employee or agent of another entity.
     Directors and officers of NBI are entitled to be indemnified against all
     liabilities and expenses incurred by the director or officer in the
     proceeding, except such liabilities and expenses as are incurred because of
     his or her willful misconduct or knowing violation of the criminal law.
     Unless a determination has been made that indemnification is not
     permissible, a director or officer also is entitled to have NBI make
     advances and reimbursement for expenses prior to final disposition of the
     proceeding upon receipt of a written undertaking from the director or
     officer to repay the amounts advanced or reimbursed if it is ultimately
     determined that he or she is not entitled to indemnification.  The Board of
     Directors of NBI also has the authority to extend to employees, agents, and
     other persons serving at the request of NBI the same indemnification rights
     held by directors and officers, subject to all of the accompanying
     conditions and obligations.

          Virginia Code (S) 13.1-700.1 permits a court, upon application of a
     director or officer, to review NBI's determination as to a director's or
     officer's request for advances, reimbursement or indemnification.  If it
     determines that the director or officer is entitled to such advances,
     reimbursement or indemnification, the court may order NBI to make advances
     and/or reimbursement for expenses or to provide indemnification, in which
     case the court shall also order NBI to pay the officer's or director's
     reasonable expenses incurred to obtain the order.  With respect to a
     proceeding by or in the right of the corporation, the court may order
     indemnification to the extent of the officer's or director's reasonable
     expenses if it determines that, considering all the relevant circumstances,
     the officer or director is entitled to indemnification even though he or
     she was adjudged liable, and may also order NBI to pay the officer's and
     director's reasonable expenses incurred to obtain the order.

          NBI maintains directors and officers liability insurance, which
     provides coverage of up to $5,000,000, subject to certain deductible
     amounts.  In general, the policy insures (i) NBI's directors and officers
     against loss by reason of any of their wrongful acts, and/or (ii) NBI
     against loss arising from claims against the directors and officers by
     reason of their wrongful acts, all subject to the terms and conditions
     contained in the policy.

          In addition to the foregoing, Paragraph (K) of Article VII of the
     Merger Agreement contains certain indemnification provisions relating to
     the Merger.

     Item 22.  Undertakings.
     -------   ------------ 
             
         (a) The undersigned registrant hereby undertakes:      
            
             (1) To file, during any period in which offers or sales are being
     made, a post-effective amendment to this registration statement:      
         
                 (i) To include any prospectus required by section 10(a)(3) of
     the Securities Act of 1933;      
         
                 (ii) To reflect in the prospectus any facts or events arising
     after the effective date of the registration statement (or the most recent
     post-effective amendment thereof) which, individually or in the aggregate,
     represent a fundamental change in the information set forth in the
     registration statement;      
         
                 (iii) To include any material information with respect to the
     plan of distribution not previously disclosed in the registration statement
     or any material change to such information in the registration statement. 
              
             Provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) do not
     apply if the registration statement is on Form S-3, Form S-8 or Form F-3,
     and the information required [or] to be included in a post-effective
     amendment by those paragraphs is contained in periodic reports filed by the
     registrant pursuant to section 13 or section 16(b) of the Securities
     Exchange Act of 1934 that are incorporated by reference in the registration
     statement.      
         
             (2) That, for the purpose of determining any liability under the
     Securities Act of 1933, each such post-effective amendment shall be deemed
     to be a new registration statement relating to the securities offered
     therein, and the offering of such securities in that time shall be deemed
     to be the actual bona fide offering thereof.      
         
             (3) To remove from registration by means of a post-effective
     amendment any of the securities being registered which remain unsold at the
     termination of the offering.      
         
             (4) If the registrant is a foreign private issuer, to file a 
     post-effective amendment to the registration statement to include any
     financial statements required by Item 3-19 of Regulation S-X at the start
     of any delayed offering or throughout a continuous offering. Financial
     statements and information otherwise required by Section 10(a)(3) of the
     Act need not be furnished, provided that the registrant includes in the
     prospectus, by means of a post-effective amendment, financial statements
     required pursuant to this paragraph (a)(4) and other information necessary
     to ensure that all other information in the prospectus is at least as
     current as the date of those financial statements. Notwithstanding the
     foregoing, with respect to registration statements on Form F-3, a 
     post-effective amendment need not be filed to include financial statements
     and information required by Section 10(a)(3) of the Act or Item 3-19 of
     Regulation S-X if such financial statements and information are contained
     in periodic reports filed with or furnished to the Commission by the
     registrant pursuant to section 13 or section 15(d) of the Securities
     Exchange Act of 1934 that are incorporated by reference in the Form F-3.

         (b)(1)  The undersigned registrant hereby undertakes that, for
     purposes of determining any liability under the Securities Act of 1933,
     each filing of the registrant's annual report pursuant to Section 13(a) or
     15(d) of the Securities Exchange Act of 1934 (and, where applicable, each
     filing of any employee benefit plan's annual report pursuant to Section
     15(d) of the Securities and Exchange Act of 1934) that is incorporated by
     reference in the registration statement shall be deemed to be a new
     registration statement relating to the securities offered therein, and the
     offering of such securities at that time shall be deemed to be the initial
     bona fide offering thereof.      

             (2) The undersigned registrant hereby undertakes as follows:  that
     prior to any public reoffering of the securities registered hereunder
     through use of a prospectus which is a part of this registration statement,
     by any person or party who is deemed to be an underwriter within the
     meaning of Rule 145(c), the issuer undertakes that such reoffering
     prospectus will contain the information called for by the applicable
     registration form with respect to reofferings by persons who may be deemed
     underwriters, in addition to the information called for by the other items
     of the applicable form.

             (3) The registrant undertakes that every prospectus (i) that is
     filed pursuant to paragraph (1) immediately preceding, or (ii) that
     purports to meet the requirements of Section 10(a)(3) of the Act and is
     used in connection with an offering of securities subject to Rule 415, will
     be filed as a part of an amendment to the registration statement and will
     not be used until such amendment is effective, and that, for purposes of
     determining any liability under the Securities Act of 1933, each such post-
     effective amendment shall be deemed to be a new registration statement
     relating to the securities offered therein, and the offering of such
     securities at that time shall be deemed to be the initial bona fide
     offering thereof.

             (4) Insofar as indemnification for liabilities arising under the
     Securities Act of 1933 may be permitted to directors, officers and
     controlling persons of the registrant pursuant to the foregoing provisions,
     or otherwise, the registrant has been advised that in the opinion of the
     Securities and Exchange Commission such indemnification is against public
     policy as expressed in the Act and is, therefore, unenforceable. In the
     event that a claim for indemnification against such liabilities (other than
     the payment by the registrant of expenses incurred or paid by a director,
     officer or controlling person of the registrant in the successful defense
     of any action, suit or proceeding) is asserted by such director, officer or
     controlling person in connection with the securities being registered, the
     registrant will, unless in the opinion of its counsel the matter has been
     settled by controlling precedent, submit to a court of appropriate
     jurisdiction the question whether such indemnification by it is against
     public policy as expressed in the Act and will be governed by the final
     adjudication of such issue.
    
         (c)  The undersigned registrant hereby undertakes to respond to      
     requests for information that is incorporated by reference into the
     prospectus pursuant to Item 4, 10(b), 11, or 13 of this form, within one
     business day of receipt of such request, and to send the incorporated
     documents by first class mail or other equally prompt means.  This includes
     information contained in documents filed subsequent to the effective date
     of the registration statement through the date of responding to the
     request.     
    
         (d)  The undersigned registrant hereby undertakes to supply by      
     means of a post-effective amendment all information concerning a
     transaction, and NBI being acquired involved therein, that was not the
     subject of and included in the registration statement when it became
     effective.

     Board of Directors                    Board of Directors
     National Bankshares, Inc.             Bank of Tazewell County
     Blacksburg, Virginia                  Tazewell, Virginia


     Board Members:

     You have requested the opinion of KPMG Peat Marwick LLP (KPMG) regarding
     the merger of NBI Interim Bank (Interim), a wholly owned bank subsidiary of
     National Bankshares, Inc. (NBI), with and into Bank of Tazewell County
     (BTC).  Specifically, you have requested us to opine that the form and
     substance of the merger of Interim with and into BTC will constitute a tax-
     free reorganization under sections 368(a)(1)(A) and 368(a)(2)(E) of the
     Internal Revenue Code of 1986, as amended, (hereinafter all section
     references are to the Internal Revenue Code unless otherwise indicated) and
     that no gain or loss will be recognized by the shareholders of BTC upon the
     receipt of NBI common stock in exchange for their BTC common stock upon
     consummation of the merger.

     Our opinion as to the tax-free reorganization treatment of the merger of
     Interim with and into BTC does not include BTC common shareholders who
     exercise their statutory dissenters' rights against the merger and receive
     cash payments.

                                     FACTS

     For what have been represented to KPMG to be valid business purposes, NBI
     and BTC want to combine their businesses.  In order to reach that result,
     the following transaction is proposed:

     1.     Pursuant to an agreement and plan of merger (the Plan) dated August
            28, 1995 between NBI and BTC, NBI will, prior to the merger
            effective date, form a Virginia banking corporation which shall be
            named and become NBI Interim Bank (Interim). Interim will have
            50,000 authorized common shares, $1.00 par value, of which 1,000
            shares shall be subscribed for by NBI pending consummation of the
            Plan.

     2.     In connection with the consummation of the Plan, NBI shall declare a
            share dividend totaling 190,768 shares of NBI common stock to be
            issued pro rata to and among the holders of NBI common stock. The
            record date of this dividend shall be prior to the merger effective
            date.

     3.     Also pursuant to the agreement and plan of merger, Interim will
            merge with and into BTC in accordance with Virginia state law, with
            BTC surviving the merger.

     4.     The actual merger will entail the following:

            (a)   On the effective date of the merger, each share of NBI Interim
                  Bank common stock issued and outstanding as of the merger
                  effective date shall be converted automatically into 1,888.209
                  shares of BTC. This shall represent all of the issued and
                  outstanding shares of BTC.

            (b)   Each share of BTC issued and outstanding immediately prior to
                  the merger effective date shall become and be converted into
                  the right to receive one share of NBI common stock, taking
                  into account the share dividends to be declared by NBI as set
                  forth in "2" above.

            (c)   On the merger effective date, holders of BTC common stock
                  shall cease to be, and shall have no rights as, shareholders
                  of BTC other than to receive NBI common stock as described in
                  "4(b)" above or cash in lieu of fractional shares as described
                  in "4(d)" below.

            (d)   No fractional shares of NBI common stock will be issued in the
                  merger, but rather NBI will pay cash in lieu thereof with the
                  amount of cash to be paid to be determined based upon the
                  closing price per share of BTC common stock as reflected on
                  the NASD Bulletin Board on the last day such stock has traded
                  prior to the merger effective date.

     5.     Each BTC shareholder has the right to dissent from the merger in
            accordance with the Virginia Stock Corporation Act. Each shareholder
            validly exercising and perfecting dissenter's rights will be
            entitled to receive from NBI the fair market value of his or her
            shares in cash.

                                REPRESENTATIONS
                                ---------------

     The following representations have been made to KPMG.  These
     representations form an integral part of the opinion rendered by KPMG. It
     is understood that KPMG has not independently verified any representation:

     (a)    The fair market value of the NBI common stock or cash to be received
            by each of the BTC shareholders in the merger will be approximately
            equal, in each instance, to the fair market value of the BTC common
            stock surrendered in the exchange.

     (b)    There is no plan or intention by the BTC shareholders to sell or
            otherwise dispose of any NBI common stock received by them in the
            transaction which would reduce their ownership of NBI common stock
            to a number of shares having, in the aggregate, a fair market value
            as of the date of the transaction of less than 50 percent of the
            fair market value of all of the formerly outstanding stock of BTC as
            of the date of the transaction. For purposes of this representation,
            shares of BTC surrendered by dissenters or exchanged for cash in
            lieu of fractional shares will be treated as outstanding stock of
            BTC on the date of the transaction. Moreover, the sale, redemption
            or other disposition of stock occurring prior or subsequent to the
            exchange which is part of the reorganization will be considered in
            determining whether there will be a 50 percent continuing interest
            through stock ownership as of the effective date of the
            reorganization.

     (c)    Following the transaction, BTC will hold at least 90 percent of the
            fair market value of its net assets and at least 70 percent of the
            fair market value of its gross assets. In addition, BTC will hold at
            least 90 percent of the fair market value of Interim's net assets
            and at least 70 percent of the fair market value of Interim's gross
            assets it held immediately prior to the transaction. For purposes of
            this representation, amounts paid by BTC or Interim to dissenters or
            shareholders who receive cash in lieu of fractional shares, amounts
            used

            by BTC or Interim to pay reorganization expenses and all redemptions
            and distributions (except for regular, normal dividends) made by BTC
            will be included as assets of BTC or Interim, respectively,
            immediately prior to the transaction.

     (d)    Prior to the transaction, NBI will be in control of Interim within
            the meaning of section 368(c) of the Code.

     (e)    Following the transaction, BTC will not issue additional shares of
            its stock that would result in NBI losing control of BTC within the
            meaning of section 368(c) of the Code.

     (f)    NBI has no plan or intention to reacquire any of its stock to be
            issued in the proposed merger.

     (g)    NBI has no plan or intention to liquidate BTC, to merge BTC with or
            into another corporation, to sell or otherwise dispose of the stock
            of BTC, or to cause BTC to sell or otherwise dispose of any of its
            assets, except for dispositions made in the ordinary course of
            business, dispositions in arm's-length transactions to avoid
            duplicative facilities or possible regulatory objections, or
            transfers of assets to a corporation controlled by BTC.

     (h)    The liabilities of Interim assumed by BTC and the liabilities to
            which the transferred assets of Interim are subject were incurred by
            Interim in the ordinary course of its business.

     (i)    Following the transaction, BTC will continue its historic business
            or use a significant portion of its historic business assets in a
            business.

     (j)    NBI, Interim, BTC and the shareholders of BTC will each pay their
            own fees and expenses incurred in connection with the merger, except
            that printing expenses for the prospectus and proxy statement will
            be shared equally by NBI and BTC.

     (k)    There is no intercorporate debt existing between NBI and BTC or
            between Interim and BTC that was issued, acquired, settled or will
            be settled at a discount.

     (l)    In the merger, shares of BTC stock representing control of BTC, as
            defined in section 368(c) of the Code, will be exchanged solely for
            voting stock of NBI. For purposes of this representation, shares of
            BTC stock exchanged for cash furnished by NBI will be treated as
            outstanding BTC stock on the date of the transaction.

     (m)    At the time of the transaction, BTC will not have outstanding any
            warrants, options, convertible securities, or any other type of
            right pursuant to which any person could acquire stock in BTC that,
            if exercised or converted, would effect NBI's acquisition or
            retention of control of BTC, as defined in section 368(c) of the
            Code.

     (N)    NBI does not own, nor has it owned during the past five years
            (except with respect to shares owned in a fiduciary capacity), any
            shares of stock of BTC.

     (o)    No two parties to the merger are investment companies within the
            meaning of such term as used in section 368(a)(2)(F)(iii) and (iv).

     (p)    On the date of the merger the fair market value of the assets of BTC
            will exceed the sum of its liabilities plus the liabilities, if any,
            to which the transferred assets are subject.

     (q)    BTC is not under the jurisdiction of a court in a Title 11 or
            similar case within the meaning of section 368(a)(3)(A).

     (r)    None of the NBI common stock being issued to the BTC shareholders
            will represent compensation for past or future services or for a
            covenant not to compete. The compensation to be paid to BTC
            directors, officers and employees who are stockholders of BTC and
            who will be employed following the merger will not be part of the
            consideration paid for their BTC common stock but will be
            commensurate in each instance with amounts paid to third parties
            bargaining at arm's-length for similar services.

     (s)    NBI will pay cash in lieu of fractional shares merely as a
            convenience and not as separately bargained for consideration. The
            total cash paid in lieu of NBI fractional shares will be less than
            one percent of the total consideration received by the BTC
            shareholders and no BTC shareholder will receive cash in lieu of
            more than one fractional share.

                                   DISCUSSION
                                   ----------

     Classification as a reorganization
     ----------------------------------

     Section 368(a)(l)(A) provides that the term "reorganization" includes a
     statutory merger.  The term statutory merger refers to a merger effected
     pursuant to the corporate laws of the United States, a state or territory,
     or the District of Columbia.  Treasury Regulation ("Reg.") section 1.368-
     2(b).

     In order to qualify as a reorganization by operation of section
     368(a)(2)(E), the transaction must meet two requirements.  First, after the
     transaction, the corporation surviving the merger (i.e., BTC) must hold
     substantially all of its properties and the properties of the merged
     corporation (i.e., Interim).  Second, the former shareholders of the
     surviving corporation (i.e., BTC) must exchange, for an amount of voting
     stock of the controlling corporation (i.e., NBI), an amount of stock in the
     surviving corporation which constitutes control of such corporation.
     Control for this purpose is defined in section 368(c) as the direct
     ownership of stock possessing at least 80 percent of the total combined
     voting power and at least 80 percent of the total number of shares of all
     other classes of stock.

     The term "substantially all" has the same meaning as the phrase is used in
     section 368(a)(1)(C).  Reg. section 1.368-2(b)(2).  Section 368(a)(1)(C)
     and the regulations promulgated thereunder do not define what constitutes
     substantially all of the properties of a corporation.  The Internal Revenue
     Service ("the Service") has established a quantitative test as to the
     amount of assets of a corporation that will satisfy the substantially all
     properties requirement for purposes of obtaining a private letter ruling.
     Under Revenue Procedure 77-37, 1977-2 C.B. 568, the "substantially all"
     requirement of section 368(a)(2)(E) is satisfied if the surviving
     corporation retains at least 90 percent of the fair market value of the net
     assets and at least 70 percent of the fair market value of the gross assets
     it held immediately
<PAGE>
 
Page 5


     before the merger, and if the surviving corporation gets at least the same
     percentages of the assets the merged subsidiary held immediately before the
     merger.

     The "ninety/seventy" guidelines are arbitrary percentages selected by the
     Service that do not necessarily represent judicial interpretations of the
     meaning of the phrase "substantially all of the properties" under various
     subdivisions of section 368.  See Louis F. Vicreck v. United States, 83-2

     What constitutes "substantially all of the properties" in a situation other
     than a request for ruling from the Service depends upon the facts and
     circumstances in each case rather than upon any particular percentage.
     Revenue Ruling 57-518, 1957-2 C.B. 253.  The Service is of the view that
     the "substantially all of the properties" requirement applies separately to
     each trade or business of the transferor corporation.

     Requisite to all reorganizations under section 368(a)(1) are:  (1) a valid
     corporate business purpose, (2) a continuity of the business enterprise
     under the modified corporate form and (3) a continuity of interest in the
     acquiring or transferee corporation on the part of those persons who
     directly or indirectly were the owners of the acquiring or transferor
     corporation prior to the reorganization.  Reg. section 1.368-1(b).  The
     term "reorganization" does not embrace the mere purchase by one corporation
     of the properties of another.  Reg. section 1.368-2(a).  These regulations
     reflect well-developed judicial interpretations of the statutory definition
     of a reorganization, the purpose of which is to exclude from the scope of
     the reorganization provisions those transactions that are in fact sales.

     Continuity of business enterprise requires that the acquiring corporation
     either continue the acquired corporation's historic business or use a
     significant portion of the acquired's historic business assets.  Reg.
     section 1.368-1(d)(2).

     The regulations under section 368(a) do not establish the amount of
     qualifying consideration necessary to satisfy the continuity of shareholder
     interest requirement.  However, the Service has promulgated a definite test
     as to the amount of consideration necessary to satisfy the continuity of
     interest requirement for purposes of obtaining a private letter ruling.
     Under Revenue Procedure 77-37, 1977-2 C.B. 568, the continuity of interest
     requirement of Reg. section 1.368-1(b) is satisfied if:

            ...there is continuing interest through stock ownership in the
            acquiring or transferee corporation...on the part of the former
            shareholders of the acquired or transferor corporation (or a
            corporation in "control" thereof within the meaning of section
            368(c) of the Code) which is equal in value, as of the effective
            date of the reorganization, to at least 50 percent of the value of
            all the formerly outstanding stock of the acquired or transferor
            corporation as of the same date. It is not necessary that each
            shareholder of the acquired or transferor corporation receive in the
            exchange, stock of the acquiring or transferor corporation, or a
            corporation in "control" thereof, which is equal in value to at
            least 50 percent of the value of his former stock interest in the
            acquired or transferor corporation, so long as one or more of the
            shareholders of the acquired or transferor corporation have a
            continuing interest through stock ownership in the acquiring or
            transferee corporation (or a corporation in "control" thereof) which
            is, in the aggregate, equal in value to at least 50 percent of the
            value of all of the formerly outstanding stock of the acquired or
            transferor corporation.

     The 50 percent definitive test of this revenue procedure does not as a
     matter of law establish the amount of qualifying consideration necessary to
     meet the continuity of interest requirement of Reg. section 1.368-1(b).  In
     other words, the continuation of a capital stock ownership in the acquiring
     corporation equal to less than 50 percent of the value of the stock of the
     acquired corporation does not in itself mark a discontinuity of interest.
     The Supreme Court in John A. Nelson Co. v. Helvering, 296 U.S. 374 (1935),
                          -------------------------------                      
     36-1 U.S.T.C. para. 9019, held that there was a

Page 6


     reorganization even though the shareholders of the acquired corporation
     received less than half of their total consideration in the form of stock
     of the acquiring corporation and received nonvoting preferred stock. It is
     only necessary that the shareholders continue to have a definite and
     substantial equity interest in the assets of the acquiring corporation.
     Revenue Ruling 61-156, 1961-2 C.B. 62.
    
     Provided that (1) the merger of Interim with and into BTC qualifies as a
     merger effected pursuant to the corporate laws of the Commonwealth of
     Virginia and is undertaken for a valid corporate business purpose as
     represented above, (2) after the transaction BTC continues its historic
     business and (3) BTC shareholders exchange for NBI voting common stock an
     amount of BTC stock meeting the continuity of shareholder interest test,
     then the merger of Interim with and into BTC will constitute a
     reorganization within the meaning of section 368(a)(1)(A) (a statutory
     merger) and section 368(a)(2)(E). NBI, BTC and Interim will each be "a
     party to the reorganization" within the meaning of section 368(b).     

     Federal income tax consequences to exchanging shareholders
     ----------------------------------------------------------

     Section 354(a)(1) provides that no gain or loss will be recognized if stock
     of a corporation which is a party to a reorganization is, pursuant to the
     plan of reorganization, exchanged solely for stock of such corporation or
     of another corporation which is a party to the reorganization.  Section
     356(a)(1) in relevant part provides that if money or other property is
     received in an exchange to which section 354 would otherwise apply, then
     gain, if any, to the recipient will be recognized to the extent of the sum
     of the money and fair market value of the other property received.  If the
     exchange has the effect of the distribution of a dividend, then the amount
     of gain recognized that is not in excess of each distributee shareholder's
     ratable share of the undistributed earnings and profits of the acquired
     corporation will be treated as a dividend.  Section 356(a)(2).  No loss
     will be recognized on the exchange.  Section 356(c).  Section 358 provides
     that shareholders are entitled to a carryover basis for stock received in a
     reorganization transaction qualifying under section 354 or 356.  Where a
     cash payment by the acquiring corporation to the shareholders of the
     acquired corporation is in lieu of fractional share interests, representing
     a mere rounding-off of the fractions in the exchange and not a separately
     bargained-for consideration, such cash payment shall be treated under
     section 302 as in redemption of the fractional share interests.  Rev. Rul.
     66-365, 1966-2 C.B. 116.

     The BTC shareholders who receive solely NBI common stock in exchange for
     their BTC common stock will not recognize any gain or loss pursuant to
     section 354(a)(1).  The tax basis which these BTC shareholders will have in
     their newly received NBI stock will be the same as their present tax basis
     in the BTC stock.  Section 358(a).

     If the property received in an exchange has the same (i.e., carryover)
     basis as the property given up, then section 1223(1) applies to determine
     the holding period for the property received.  Section 1223(1) provides
     that the period during which the taxpayer held the property surrendered in
     the exchange is added to the period he or she holds the property received
     in the exchange in order to determine the holding period of the property
     received.

     The tacking of the previous holding period applies only if the property
     exchanged was a capital asset in the taxpayer's hands at the time of the
     exchange.  Section 1223(1).  The status of property as a capital asset is
     determined under section 1221, which defines "capital asset" as any
     property of a taxpayer other than property within specified
     classifications.  As a general rule, stock of a corporation would be
     treated as a capital asset under this section.  Provided that his or her
     BTC stock is a capital asset, then each BTC shareholder will be able to
     include his or her respective ownership period of the BTC stock in
     determining the holding period of the NBI stock received in the proposed
     transaction.

     The payment of cash in lieu of fractional share interests of NBI common
     stock will be treated as if the fractional share was distributed to BTC
     shareholders as part of the exchange and then redeemed by NBI.  These
     payments will be treated as having been received by BTC shareholders as
     distributions in full payment in exchange for the stock redeemed as
     provided in section 302(a).  Gain or loss to the shareholder is determined
     based on the difference

     between the full amount of cash received and the adjusted basis allocable
     to the fractional share. Provided that his or her BTC stock is a capital
     asset, then the gain or loss recognized as a result of receiving cash in
     lieu of a fractional share will be a capital gain or loss to the
     shareholder.
    
     BTC will not recognize any gain or loss upon the receipt by it of the
     assets of Interim, when Interim is merged with and into BTC, solely for
     shares of NBI stock.  Section 1032.  NBI will not recognize any gain or
     loss upon the exchange of its shares of Interim stock solely in exchange
     for shares of BTC stock.  Section 354.     



                                  CONCLUSION
                                  ----------

     Based on the foregoing facts and representations, it is the opinion of KPMG
     that the merger of Interim with and into BTC and the acquisition of BTC by
     NBI, in accordance with federal banking and Virginia state law, will be
     treated as a tax-free reorganization under section 368(a)(1)(A) and section
     368(a)(2)(E) of the Code.

     The federal income tax effects of the reorganization to the BTC
     shareholders are summarized as follows:

     1.     No gain or loss will be recognized by the shareholders of BTC who
            receive solely shares of NBI voting common stock (including a
            fractional share interest to which they are entitled) for their BTC
            common stock upon consummation of the exchange.

     2.     The basis of the NBI common stock received (including a fractional
            share interest to which they are entitled) by such BTC shareholders
            will be the same as the basis of the BTC stock surrendered in the
            exchange. Provided that the BTC stock surrendered was a capital
            asset in the shareholder's hands immediately prior to the exchange,
            the holding period of the NBI stock (including a fractional share
            interest to which they are entitled) will include the holding period
            of the BTC stock.

     3.     Cash received by a BTC shareholder in lieu of a fractional share
            interest in NBI common stock will be treated as received in full
            payment in exchange for such fractional share interest. Provided the
            fractional share would have constituted a capital asset in the hands
            of such holder, the shareholder will recognize a capital gain or
            loss in an amount equal to the difference between the amount of cash
            received and the portion of the adjusted tax basis in the BTC common
            stock allocable to the fractional share interest.
    
     4.     NBI, BTC and Interim, as parties to the reorganization, will not
            recognize any gain or loss as a result of the merger of Interim with
            and into BTC.    

                                      Very truly yours,

                                      KPMG Peat Marwick LLP
