                                 June 12, 1998



To the Shareholders of
Ballston Bancorp, Inc.

         You are cordially invited to attend the Annual Meeting of Shareholders
(the "Annual Meeting") of Ballston Bancorp, Inc. ("Ballston"), the holding
company for The Bank of Northern Virginia ("The Bank"), which will be held on
Wednesday, July 15, 1998 at 4:00 p.m., local time at The Bank of Northern
Virginia, 1010 North Glebe Road, Arlington, Virginia.

         At the Annual Meeting, you will be asked to consider and vote upon a
proposal to approve the Agreement and Plan of Merger, dated as of March 11,
1998, and the related Plan of Merger (collectively, the "Merger Agreement")
pursuant to which Ballston will be merged (the "Merger") with and into
MainStreet Financial Corporation (formerly MainStreet BankGroup Incorporated)
("MSBC"). Under the terms of the Merger Agreement, each share of common stock,
par value $0.20 per share, of Ballston will be converted into that fraction of a
share of MSBC common stock having a market value of $12.04, provided that a
minimum of 0.4025 shares and a maximum of 0.4920 shares of MSBC common stock
will be issued for each share of Ballston common stock. Cash will be paid in
lieu of the issuance of any fractional shares.

         Danielson Associates Inc., an investment banking firm, has issued its
opinion to your board of directors regarding the fairness from a financial point
of view of the consideration to be received by the shareholders of Ballston
pursuant to the Merger Agreement as of the date of such opinion. A copy of the
opinion is attached as Appendix II to the Proxy Statement/Prospectus.

         THE BOARD OF DIRECTORS HAS UNANIMOUSLY (WITH ONE DIRECTOR NOT PRESENT)
APPROVED THE PROPOSED MERGER AND RECOMMENDS THAT SHAREHOLDERS VOTE THEIR SHARES
"FOR" APPROVAL OF THE MERGER. THE AFFIRMATIVE VOTE OF A MAJORITY OF BALLSTON'S
OUTSTANDING SHARES ENTITLED TO VOTE IS NECESSARY TO APPROVE THE MERGER.
ACCORDINGLY, FAILURE TO VOTE, EITHER BY FAILING TO RETURN YOUR PROXY OR FAILING
TO VOTE IN PERSON AT THE ANNUAL MEETING, WILL HAVE THE SAME EFFECT AS A VOTE
AGAINST THE MERGER.

         At the Annual Meeting, you will also be asked to consider and vote upon
the election of directors to serve on the Board of Directors until the next
annual meeting or their successors are elected and qualified or, if earlier,
until consummation of the Merger, and the appointment of Stoy, Malone & Company,
P.C. as the independent auditors of Ballston for 1998 or, if earlier, until
consummation of the Merger.

         The accompanying Notice of Annual Meeting of Shareholders and the Proxy
Statement/Prospectus describe the matters to be acted upon at the Annual
Meeting. Shareholders are urged to review carefully the attached Proxy
Statement/Prospectus, including the Appendices, which together describe the
Merger and its terms and conditions in detail.

                                         Sincerely,


                                         Robert F.  Kelleher
                                         Chairman of the Board,
                                         President and Chief Executive Officer

                    NOTICE OF ANNUAL MEETING OF SHAREHOLDERS
                          TO BE HELD ON JULY 15, 1998

To the Holders of Common Stock of Ballston Bancorp, Inc.

NOTICE IS HEREBY GIVEN that the Annual Meeting of Shareholders (the "Annual
Meeting") of Ballston Bancorp, Inc. ("Ballston") will be held on Wednesday, July
15, 1998, at 4:00 p.m., local time at The Bank of Northern Virginia, 1010 North
Glebe Road, Arlington, Virginia. The Annual Meeting is for the purpose of
considering and voting upon the following matters, each of which is set forth
more completely in the accompanying Proxy Statement/Prospectus:

1.       To approve the Agreement and Plan of Merger, dated as of March 11,
1998, and the related Plan of Merger (collectively, the "Merger Agreement")
pursuant to which Ballston will be merged (the "Merger") with and into
MainStreet Financial Corporation (formerly MainStreet BankGroup Incorporated)
("MSBC"). Under the terms of the Merger Agreement, each share of common stock,
par value $0.20 per share, of Ballston will be converted into that fraction of a
share of MSBC common stock having a market value of $12.04, provided that a
minimum of 0.4025 shares and a maximum of 0.4920 shares of MSBC common stock
will be issued for each share of Ballston common stock. Cash will be paid in
lieu of issuance of fractional shares. The Merger Agreement is attached as
Appendix I and is described in the accompanying Proxy Statement/Prospectus.

2.       To elect the directors to serve until the 1999 annual meeting of
shareholders or their successors have been elected and qualified or, if earlier,
until the consummation of the Merger.

3.       To ratify the appointment of Stoy, Malone & Company, P.C., to serve as
independent auditors of Ballston for the fiscal year ending December 31, 1998
or, if earlier, until the consummation of the Merger.

4.       To transact such other business as may properly come before the Annual
Meeting or any adjournment or postponement thereof.

         Only shareholders of record at the close of business on the record
date, June 11, 1998, are entitled to notice of and to vote at the Annual Meeting
and any adjournments thereof. The affirmative vote of the holders of a majority
of outstanding Ballston Common Stock entitled to vote is necessary to approve
the Merger. Accordingly, failure to vote, either by failing to return your proxy
or failing to vote in person at the Annual Meeting, will have the same effect as
a vote against the Merger. We urge you to execute and return the enclosed proxy
as soon as possible to ensure that your shares will be represented at the Annual
Meeting. Your proxy may be revoked in the manner described in the accompanying
Proxy Statement/Prospectus at any time before it has been voted at the Annual
Meeting.

                                            By Order of the Board of Directors


                                            Brian D. Alprin
                                            Treasurer and Secretary
Washington, D.C.
June 12, 1998

         THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT YOU VOTE FOR THE
PROPOSAL STATED ABOVE. PLEASE SIGN AND RETURN THE ENCLOSED PROXY AS PROMPTLY AS
POSSIBLE, WHETHER OR NOT YOU PLAN TO ATTEND THE ANNUAL MEETING IN PERSON. YOU
MAY REVOKE YOUR PROXY AT ANY TIME BEFORE IT IS VOTED AT THE ANNUAL MEETING.

                            Ballston Annual Meeting

Time, Date, Place and Purpose

         The Annual Meeting will be held on Wednesday, July 15, 1998 at 4:00
p.m. local time at The Bank of Northern Virginia, 1010 North Glebe Road,
Arlington, Virginia, to consider and vote upon a proposal to approve the Merger
Agreement and the transactions contemplated thereby. A copy of the Merger
Agreement is attached hereto as Appendix I.

Record Date; Vote Required

         The record date ("Record Date") for determining Ballston shareholders
entitled to notice of and to vote at the Annual Meeting is June 11, 1998. The
presence in person or by proxy of the holders of forty percent (40%) of the
total number of issued and outstanding shares of Ballston Common Stock is
necessary to constitute a quorum at the Annual Meeting. Assuming a quorum is
present, an affirmative vote of at least a majority of the outstanding shares is
necessary to approve the Merger Agreement. As of the Record Date, the directors
and executive officers and their affiliates beneficially own approximately 48.5%
of Ballston Common Stock. In addition, an affirmative vote of a plurality of the
votes cast is necessary to elect the directors and an affirmative vote of the
majority of the votes cast is necessary for the ratification of auditors. In the
event a quorum is not present or there are insufficient votes to approve any
proposal, the Annual Meeting may be adjourned from time to time by a majority of
those present in person or by proxy in order to permit, as appropriate, further
solicitation of proxies by the Ballston Board.

Stock Held By Ballston Affiliates

         The directors and executive officers of Ballston and their affiliates
beneficially owned, as of the Record Date, 784,716 shares, or 48.5%, of Ballston
Common Stock. The directors and executive officers of Ballston have all
indicated that they will vote their shares of Ballston Common Stock in favor of
the proposal to approve the Merger Agreement.

                                   THE MERGER

Effective Date

         The Merger is expected to be consummated in the third quarter of 1998.
Subject to the terms and conditions set forth herein, including receipt of all
required regulatory approvals, the Merger shall become effective on the date and
time the Virginia State Corporation Commission ("SCC") issues a certificate of
merger reflecting the Merger (the "Effective Date"). Ballston and MSBC each has
the right, acting unilaterally, to terminate the Agreement should the Merger not
be completed by September 30, 1998. See Proposal I - "The Merger - Termination."

Merger Consideration

         Under the terms of the Merger Agreement, each outstanding share of
Ballston Common Stock has been valued at $12.04. The number of shares to be
delivered for each share of Ballston Common Stock will be determined by dividing
$12.04 by the average of the mean between the bid price and the asked price as
reported on the Nasdaq National Stock Market for each of the 20 trading days
preceding the tenth calendar day prior to the Effective Date (the "Average MSBC
Share Price"). If such quotient is less than 0.4025, the Exchange Ratio shall be
0.4025 and if such quotient is more than 0.4920, the Exchange Ratio shall be
0.4920. The Exchange Ratio will be adjusted to reflect any consolidation,
split-up, other subdivisions or combinations of MSBC common stock, any dividend
payable in MSBC common stock, or any capital reorganization involving the
reclassification of MSBC common stock. See "Proposal I - The Merger - General."

         On June 8, 1998, the most recent date for which it was practicable to
obtain market price data prior to the printing of this Proxy
Statement/Prospectus, the closing sales price per share of MSBC common stock was
$28.9375.

Exchange of Certificates; Delivery of MSBC Common Stock and Payment for
Fractional Shares

         As soon as practicable after the Effective Date, MSBC shall cause
Registrar and Transfer Company, Post Office Box 1010, Cranford, New Jersey,
acting as the exchange agent (the "Exchange Agent"), to mail to each Ballston
shareholder (other than dissenting shareholders) a letter of transmittal and
instructions for use in order to surrender the certificates formerly
representing shares of Ballston Common Stock. Cash (without interest) will be
paid to Ballston shareholders in lieu of the issuance of any fractional shares
in an amount equal to the fraction of a share of MSBC common stock to which such
shareholder would otherwise be entitled multiplied by the Average MSBC Share
Price. See "Proposal I - The Merger - Exchange of Certificates; Payment for
Fractional Shares."

Opinion of Ballston's Financial Advisor

         Ballston engaged Danielson Associates Inc. ("Danielson") to render
financial advisory and investment banking services in connection with Ballston
management's decision to explore various methods to enhance Ballston shareholder
value. Pursuant to such engagement, Danielson has evaluated the fairness of the
consideration to be received by Ballston shareholders pursuant to the Merger.
Danielson has delivered to Ballston an opinion dated March 11, 1998, stating
that, as of such date, based on its review and assumptions and subject to the
limitations described therein, the merger consideration was fair, from a
financial point of view, to Ballston's shareholders. A copy of Danielson's
opinion is attached as Appendix II to this Proxy Statement/Prospectus and should
be read in its entirety. See "Proposal I - The Merger - Opinion of Ballston's
Financial Advisor."

Federal Income Tax Consequences

         It is anticipated that the Merger will be a tax-free reorganization for
federal income tax purposes. Ballston's shareholders will receive MSBC common
stock for their Ballston Common Stock under the terms of the Merger Agreement.
Upon this conversion, Ballston's shareholders will generally recognize no gain
or loss. Upon receipt of cash for fractional shares of Ballston Common Stock,
Ballston's shareholders will recognize gain, but not in an amount in excess of
cash received. See "Proposal I - The Merger - Federal Income Tax Consequences."

Accounting Treatment

         The Merger, when consummated, will be accounted for under the pooling
of interests method of accounting.  See "Proposal I - The Merger - Accounting
Treatment."

Conditions to the Merger

         Consummation of the Merger is subject, among other things, to the
approval of the Merger Agreement by the requisite vote of Ballston shareholders
and the receipt of all requisite regulatory approvals and satisfaction of other
conditions contained in the Merger Agreement. See "Proposal I - The Merger -
Conditions to the Merger."

Effect of the Merger on Shareholders' Rights

         If the Merger Agreement is approved, Ballston's shareholders will
become shareholders of MSBC, and their rights as shareholders of MSBC will be
determined by the Virginia Corporation Code ("Virginia Code") and by MSBC's
Articles of Incorporation and Bylaws. The rights of Ballston shareholders are
currently governed by the Delaware General Corporation Law ("DGCL") and by
Ballston's Certificate of Incorporation and Bylaws. See "Proposal I - The Merger
- - Effect of the Merger on Shareholders' Rights."

Rights of Dissenting Shareholders

         Ballston's shareholders are entitled to exercise dissenters' rights
under Section 262 of the DGCL in connection with the proposal to approve the
Merger Agreement.  See "Proposal I - The Merger - Rights of Dissenting
Shareholders."

Interests of Certain Persons in the Merger

         Certain members of Ballston's management and Board of Directors have
interests in the Merger in addition to their interests as shareholders.  See
"Proposal I - The Merger - Interests of Certain Persons in the Merger."

                       COMPARATIVE PER SHARE INFORMATION

         The following table presents historical and pro forma per share data
for MSBC, restated for the pooling of interests with Regency Financial Corp.
which was completed in the first quarter of 1998, and historical and equivalent
pro forma per share data for Ballston. The pro forma combined amounts give
effect to an assumed Exchange Ratio of .4161 shares of MSBC Common Stock for
each share of Ballston Common Stock (based on the last sale price of MSBC Common
Stock on June 8, 1998 of $28.9375). The equivalent pro forma share amounts allow
comparison of historical information about one share of Ballston Common Stock to
the corresponding data about what one share of Ballston Common Stock will equate
to in the combined corporation and are computed by multiplying the pro forma
combined amounts by an assumed Exchange Ratio of .4161 (ratably apportioned). As
discussed in "Proposal I -- The Merger -- General," the final Exchange Ratio
will be determined based on the average MSBC Share Price as reported on the
Nasdaq National Market for each of the 20 trading days preceding the tenth
calendar day prior to the Effective Date. The following table is based on the
assumption that all issued and outstanding shares of Ballston Common Stock are
converted into shares of MSBC Common Stock. The Merger is reflected under the
pooling of interests method of accounting and pro forma information is derived
accordingly.

         The per share data included in the following table should be read in
conjunction with the consolidated financial statements of MSBC incorporated by
reference herein and the financial statements of Ballston included herein and
the notes accompanying all such financial statements. The data presented below
are not necessarily indicative of the results of operations which would have
been obtained if the Merger had been consummated in the past or which may be
obtainable in the future.

                                  INTRODUCTION

      This Proxy Statement/Prospectus is being furnished to Ballston
Shareholders in connection with the solicitation of proxies by the Ballston
Board for use at the Ballston Annual Meeting to be held on Wednesday, July 15,
1998, at The Bank of Northern Virginia, 1010 North Glebe Road, Arlington,
Virginia, at 4:00 p.m. local time or at any adjournments thereof. The purpose of
the Annual Meeting is to consider and vote upon a proposal to approve the Merger
Agreement and the transactions contemplated thereby, as more fully set forth in
the Notice of Annual Meeting accompanying this Proxy Statement/Prospectus.

      The Board of Directors of Ballston unanimously (with one director not
present) approved the Merger Agreement and recommends that Ballston Shareholders
vote FOR its approval.

                            BALLSTON ANNUAL MEETING

Record Date; Vote Required

      The Board of Directors of Ballston has fixed the close of business on June
11, 1998, as the Record Date for determining shareholders entitled to notice of
and to vote at the Annual Meeting, and accordingly, only holders of Ballston
Common Stock of record at the close of business on that day will be entitled to
notice of and vote at the Annual Meeting. The number of shares of Ballston
Common Stock outstanding on the Record Date was 1,619,474, each of such shares
being entitled to one vote. As of the Record Date, the directors and executive
officers and their affiliates beneficially owned approximately 48.5% of Ballston
Common Stock.

      The presence in person or by proxy of the holders of forty percent (40%)
of the total number of issued and outstanding shares of Ballston Common Stock is
necessary to constitute a quorum at the Annual Meeting. As to the approval of
the Merger Agreement, by checking the appropriate box, a shareholder may: (i)
vote "FOR" approval of the Merger Agreement; (ii) vote "AGAINST" approval of the
Merger Agreement; or (iii) "Abstain." Because the affirmative vote of the
holders of at least a majority of the outstanding shares is required to approve
the Merger Agreement and the transaction contemplated thereby, abstentions and a
failure to vote will have the effect of a vote against the Merger Agreement. In
addition, brokers who hold shares in street name for individuals who are the
beneficial owners of such shares are prohibited from giving a Proxy to vote
shares held for such individuals on the Merger Agreement without specific
instructions from such individuals. The failure of such individuals to provide
specific instruction with respect to their shares of Ballston Common Stock to
their broker will have the effect of a vote against the Merger Agreement.

      As to the election of directors, the Proxy being provided by the Ballston
Board enables a Ballston shareholder to vote for the election of the nominees
proposed by the Ballston Board, or to withhold authority to vote for one or more
of the nominees being proposed. Directors are elected by a plurality of the
votes cast at the Annual Meeting without regard to broker non-votes or proxies
as to which authority to vote for one or more of the nominees being proposed is
withheld.

<PAGE>



      As to the ratification of independent auditors, by checking the
appropriate box, a shareholder may: (i) vote "FOR" the item, (ii) vote "AGAINST"
the item, or (iii) vote to "ABSTAIN" on such item. The affirmative vote of the
majority of the votes cast is required for the ratification of independent
auditors, without regard to broker non-votes or, proxies marked "ABSTAIN" as to
that matter. Unless required by law, all other matters that may properly come
before the Annual Meeting shall be determined by a majority of those votes cast
by shareholders without regard to broker non- votes or proxies marked "ABSTAIN"
as to that matter.

      The directors and executive officers of Ballston (including certain of
their related interests) beneficially own, as of the Record Date, and are
entitled to vote at the Annual Meeting 48.5% of the issued and outstanding
shares of Ballston Common Stock.

Proxies; Revocation; Solicitation

      If the Proxy is properly executed and returned to Ballston in time to be
voted at the Ballston Annual Meeting, the shares represented thereby will be
voted in accordance with the instructions marked thereon. Ballston proxies that
are executed, but as to which no instructions have been marked, will be voted
FOR the approval of the Merger Agreement. Should any other matter properly come
before the Ballston Annual Meeting, the persons named as proxies in the Ballston
proxy, acting by a majority of those proxies present, will have discretionary
authority to vote on such matters in accordance with their judgment. However, no
proxy which is voted "against" the proposal to approve and adopt the Merger
Agreement will be voted in favor of any such adjournment or postponement. As of
the time of the preparation of this Proxy Statement/Prospectus, the Ballston
Board does not know of any matter, other than those matters referred to in the
Ballston Notice of Annual Meeting of Shareholders, to be presented for action at
the Ballston Annual Meeting.

      The cost of soliciting proxies will be borne by Ballston. In addition to
use of the mails, proxies may be solicited personally or by telephone,
telecopier or telegraph by officers, directors or employees of Ballston, who
will not be specially compensated for such solicitation activities.

      A proxy may be revoked by the person giving the proxy at any time prior to
the close of voting. Prior to the Annual Meeting a proxy may be revoked by
filing with the Secretary of Ballston at Ballston Bancorp, Inc., 1667 K Street,
N.W., Suite 700, Washington, D.C. 20006, a written revocation or a duly executed
proxy bearing a later date. During the Annual Meeting a proxy may be revoked by
filing a written revocation or a duly executed proxy bearing a later date with
the Secretary of the Annual Meeting prior to the close of voting or by attending
the Annual Meeting and voting in person. Any shareholder of record may attend
the Annual Meeting and vote in person, whether or not a proxy has previously
been given.

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

                            PROPOSAL I - THE MERGER

      The following information concerning the Merger, insofar as it relates to
matters contained in the Merger Agreement, is qualified in its entirety by
reference to the full text of the Merger Agreement which is attached as Appendix
I to this Proxy Statement/Prospectus and is incorporated by reference.

General

      On March 11, 1998, MSBC and Ballston entered into the Merger Agreement
which provides for the Merger of Ballston with and into MSBC. Under the terms of
the Merger Agreement, each outstanding share of Ballston Common Stock has been
valued at $12.04. The number of shares to be delivered for each share of
Ballston Common Stock will be determined by dividing $12.04 by the Average MSBC
Share Price as reported on the Nasdaq National Stock Market for each of the 20
trading days preceding the tenth calendar day prior to the Effective Date. If
such quotient is less than 0.4025, the Exchange Ratio shall be 0.4025 and if
such quotient is more than 0.4920, the Exchange Ratio shall be 0.4920. Cash will
be paid in lieu of the issuance of any fractional shares. The Exchange Ratio
will be adjusted to reflect any consolidation, split-up, other subdivisions or
combinations of MSBC common stock, any dividend payable in MSBC common stock, or
any capital reorganization involving the reclassification of MSBC common stock.

      Ballston has agreed that prior to the Effective Date, it will operate its
business substantially as presently operated and in the ordinary course, and
consistent with such operations will use reasonable efforts to preserve intact
its present business operation and keep available its present officers and
employees material to its business and operations.

Background of the Merger

      In recent years, a number of banks, bank holding companies, and other
interested parties have contacted Ballston and suggested exploring the
possibility of a merger or acquisition. In general, however, the Ballston Board
considered a merger or acquisition to be either premature or not in the best
interests of Ballston. As a result, the Board elected not to pursue such
preliminary expressions of interest and instead focused on a strategy of
internal growth, with inconsistent and ultimately limited results.

      The Board and management of Ballston have followed, however, the trend in
the banking industry generally and, more specifically, in The Bank's Northern
Virginia market area, towards increasing levels of competition and significant
consolidation. Ballston recognizes that the larger entities that result from
such consolidations may acquire substantial competitive advantages, including
greater diversity in their loan portfolios, improved access to capital and
funding and the ability to spread costs of new products, services and research
and development over a wider customer base.

<PAGE>


      During the first quarter of 1997 Ballston received an unsolicited overture
from Abigail Adams National Bancorp, Inc. ("AANB"), which resulted in subsequent
discussions between Ballston and AANB concerning shareholder welfare, cultural
affinities, and other considerations. At the conclusion of these discussions, on
June 23, 1997, Ballston signed a definitive agreement to merge with and into a
subsidiary of AANB (the "AANB Merger"). However, at the Special Meeting of
Shareholders of AANB held on December 31, 1997, the shareholders of AANB failed
to approve the AANB Merger and, as a result, the definitive agreement between
Ballston and AANB was terminated.

      During early January 1998, following the termination of the definitive
agreement between Ballston and AANB, a financial institution in the Washington,
D.C. metropolitan area contacted an officer of Ballston regarding a possible
affiliation with Ballston. In light of this expression of interest and the
likelihood of receiving other expressions of interest in a possible affiliation,
management of Ballston retained Danielson to provide financial and business
advice regarding the strategic future of Ballston. As discussed with Danielson,
the primary criterion of management and the Board for any possible strategic
decision, including affiliation with a financial institution, was the
maximization of the long-term value of Ballston to its shareholders.

       During the remainder of the month of January, Danielson and Robert F.
Kelleher, Chairman of the Board, President and Chief Executive Officer of
Ballston, each were contacted by several other financial institutions in the
Washington, D.C. metropolitan area, regarding a possible affiliation with
Ballston. Between January 29 and February 5, 1998, Danielson met with
representatives of each of the financial institutions that had expressed
interest in establishing an affiliation with Ballston, including several that
Danielson had identified, and Danielson requested all submissions of interest to
be received by February 17, 1998.

      On February 11, 1998, Danielson met with the Board and identified and
analyzed the financial institutions that had expressed an interest in a possible
affiliation with Ballston. Between February 14 and 17, 1998, Danielson received
several formal submissions of interest from various institutions (the
"interested parties"), including one from MSBC. On February 18, 1998, the Board
met with its legal counsel and financial advisor to discuss the submissions of
interest, while management and its advisors continued to engage in discussions
with several interested parties. As a result of these discussions, MSBC agreed
to revise its initial submission of interest, subject to satisfactory completion
of its remaining due diligence, to include financial terms more favorable to
Ballston. For the reasons discussed below under "Reasons for the Merger," the
Board instructed management and Danielson to pursue further negotiations with
MSBC. Between March 5 and 8, 1998, representatives of MSBC conducted additional
due diligence of Ballston and, upon completion of that review, MSBC negotiated a
form of definitive merger agreement with Ballston.

      On March 11, the Board reviewed the proposal of MSBC and met with
Danielson and Ballston's legal counsel to discuss and review the final proposal
and terms of the Merger Agreement. Danielson presented a detailed analysis of
the final proposal to the Board and provided its oral opinion that the Exchange
Ratio was fair to Ballston's shareholders from a financial point of view.

      On the basis of a variety of factors discussed below under "Reasons for
the Merger," including the opinion from Danielson that the MSBC proposal was
fair to Ballston's shareholders from a financial point of view, the Board
concluded that accepting MSBC's offer was in the best interest of Ballston and
its shareholders. Accordingly, for all of the reasons discussed above, on March
11, 1998, Ballston's Board unanimously (with one Board member not present)
accepted MSBC 's offer and authorized execution of the Merger Agreement.

Reasons for the Merger

      In reaching its conclusion to approve the Merger Agreement, the Board
considered a number of factors. The Board did not assign any relative or
specific weights to the factors considered. Among other things, the Board
considered: (i) the Merger consideration in relation to the book value, assets
and earnings of Ballston and MSBC; (ii) information concerning the financial
condition, results of operations and prospects of Ballston and MSBC, including
the return on assets and return on equity; (iii) the financial terms of other
recent business combinations in the banking industry; and (iv) the opinion of
Danielson as to the fairness of the Merger consideration to Ballston's
shareholders from a financial point of view.

      The Board believes that the terms of the Merger Agreement, which are the
product of arms-length negotiations between MSBC and Ballston, are in the best
interest of Ballston and its shareholders. In the course of reaching its
determination, the Board consulted with legal counsel with respect to its legal
duties, the terms of the Merger Agreement and the issues related thereto; with
its financial advisor with respect of the financial aspects and fairness of the
transaction; and with senior management of MSBC regarding, among other things,
retention of Ballston employees, customer service and depth of MSBC management.
In reaching its determination to approve the Merger Agreement, the Board
considered various factors it deemed material, including:

      (a) The Board analyzed information with respect to the financial
condition, results of operations, businesses and prospects of Ballston and MSBC.
In this regard, the Board analyzed the options of having Ballston effect a
transaction with a third party or continue on a stand-alone basis. The range of
values on the basis of a combination with a third party were determined
generally to exceed the present value of Ballston shares on a stand-alone basis
under business strategies which could be reasonably implemented by Ballston.

      (b) The Board considered the oral opinion (which was subsequently
confirmed in writing) of Danielson that, as of March 11, 1998, the Exchange
Ratio was fair to Ballston's shareholders from a financial point of view. See
"Opinion of Ballston's Financial Advisor."

      (c) The Board considered the current operating environment, including, but
not limited to, the continued consolidation activity and increasing competition
in the banking and financial services industries, the prospect for further
changes in these industries, and the importance of being able to capitalize on
developing opportunities in these industries. This information has been
periodically reviewed by the Board at its regular board meetings and was also
discussed between the Board and Ballston's various advisors.


                                     - 16 -

<PAGE>




      (d) The Board considered the other terms of the Merger Agreement,
including the tax-free nature of the transaction.

      (e) The Board considered the detailed financial analyses and other
information with respect to Ballston and MSBC discussed, as well as the Board's
own knowledge of Ballston and MSBC and their respective businesses. In this
regard, the latest publicly-available financial and other information for MSBC
was analyzed, including a comparison to publicly available financial and other
information for other similar institutions.

      (f) The Board considered the value of Ballston Common Stock if Ballston
continued as a stand-alone entity compared to the effect of Ballston combining
with MSBC in light of the factors summarized above and the current economic and
financial environment, including, but not limited to, other possible strategic
alternatives, the results of the contacts and discussions between Ballston,
MSBC, and Danielson and various third parties and the belief of the Board and
management that the Merger offered the best transaction available to Ballston
and its shareholders.

      (g) The Board considered the likelihood of the Merger being approved by
the appropriate regulatory authorities, including factors such as market share
analysis, Community Reinvestment Act rating at that time and the estimated pro
forma financial impact of the Merger on MSBC.

      The merger consideration of approximately $12.04 per share for each
outstanding share of Ballston Common Stock in the form of MSBC common stock,
subject to adjustment under certain conditions, represents an exchange premium
of approximately 2.4 times Ballston's book value at December 31, 1997.

      The foregoing discussion of the information and factors considered by the
Board is not intended to be exhaustive, but constitutes the material factors
considered by the Board. In reaching its determination to approve and recommend
the Merger Agreement, the Board did not assign any relative or specific weights
to the foregoing factors, and individual directors may have weighted factors
differently. After deliberating with respect to the Merger and the other
transactions contemplated by the Merger Agreement, considering, among other
things, the matters discussed above and the opinion of Danielson referred to
above, the Board approved and adopted the Merger Agreement as being in the best
interests of Ballston and its shareholders.

Opinion of Ballston's Financial Advisor

      Ballston retained Danielson to provide financial and business advice
regarding the strategic future of Ballston. Danielson is regularly engaged in
the valuation of banks, bank holding companies, and thrifts in connection with
mergers, acquisitions, and other securities transactions and has knowledge of,
and experience with, the Mid-Atlantic banking markets and banking organizations
operating in those markets. Danielson was selected by Ballston because of its
knowledge of, expertise with, and reputation in the financial services industry.

      In such capacity, Danielson reviewed the Merger Agreement with respect to
the pricing and other terms and conditions of the Merger, but the decision as to
accepting the offer was ultimately made by the Board. Danielson rendered its
oral opinion to the Ballston Board, which it subsequently confirmed in writing,
that as of the date of such opinion, the financial terms of the MSBC offer were
"fair" to Ballston and its shareholders. No limitations were imposed by the
Ballston Board upon Danielson with respect to the investigation made or
procedures followed by it in arriving at its opinion.

      In arriving at its opinion, Danielson (a) reviewed certain business and
financial information relating to Ballston and MSBC, including MSBC's annual
report for the fiscal year ended December 31, 1997, Ballston's unaudited
financial statements for December 31, 1997, and call report data from 1989 to
1996 including quarterly reports for 1997; (b) discussed the past and current
operations, financial condition and prospects of Ballston with its senior
executives; (c) analyzed the pro forma impact of the merger on MSBC's earnings
per share, capitalization, and financial ratios; (d) reviewed the reported
prices and trading activity for the MSBC common stock and compared them to
similar bank holding companies; (e) reviewed and compared the financial terms,
to the extent publicly available, with comparable transactions; (f) reviewed the
Merger Agreement and certain related documents; and (g) considered such other
factors as were deemed appropriate.

      Danielson did not obtain any independent appraisal of assets or
liabilities of Ballston or MSBC or their respective subsidiaries. Further,
Danielson did not independently verify the information provided by Ballston or
MSBC and assumed the accuracy and completeness of all such information.

      In arriving at its opinion, Danielson performed a variety of financial
analyses. Danielson believes that its analyses must be considered as a whole and
that consideration of portions of such analyses and the factors considered
therein, without considering all the factors and analyses, could create an
incomplete view of the analyses and the process underlying Danielson's opinion.
The preparation of a fairness opinion is a complex process involving subjective
judgments and is not necessarily susceptible to partial analysis and summary
description.



                                     - 18 -

      In its analyses, Danielson made certain assumptions with respect to
industry performance, business and economic conditions, and other matters, many
of which were beyond Ballston's or MSBC's control. Any estimates contained in
Danielson's analyses are not necessarily indicative of future results of value,
which may be significantly more or less favorable than such estimates. Estimates
of the value of companies do not purport to be appraisals or necessarily reflect
the prices at which companies or their securities may actually be sold.

      The following is a summary of selected analyses considered by Danielson in
connection with its opinion letter.

Pro Forma Merger Analyses. Danielson analyzed the changes in the amount of
earnings and book value represented by the receipt of about $19.5 million for
all of the outstanding shares of Ballston Common Stock, which will be paid in
MSBC common stock. The analysis evaluated, among other things, possible dilution
in earnings and capital per share for MSBC common stock.

      Specifically, Danielson determined that based upon MSBC's current
announced transactions which include Regency Financial Shares, Inc. ("Regency")
and Ballston, MSBC had on a historic basis diluted its 1997 earnings per share
by approximately $0.04 per share or 2.8%. Similarly, Danielson determined that
based upon Regency and Ballston and a December 31, 1997 financial date, MSBC
will benefit from $0.06 per share in accretion to equity per share, or .5%
accretion.

Comparable Companies. Danielson compared Ballston's (a) tangible capital of
10.31% of assets as of December 31, 1997, (b) 1.74% of assets nonperforming as
of December 31, 1997, and (c) net operating income of 1.77% of average assets
for 1997, with the medians for selected Virginia banks, which Danielson deemed
comparable. These banks included Community Bank of Northern Virginia, The
Horizon Bank of Virginia, Rockingham Heritage Bank, Virginia Commerce Bank, N.A.
and Virginia Heartland Bank. Their medians as of September 30, 1997 or for the
first nine months of 1997, annualized, were (a) tangible capital of 8.37% of
assets, (b) .96% of assets nonperforming, and (c) net operating income of 1.65%
of average assets.

      Danielson also compared MSBC's (a) stock price as of March 9, 1998 equal
to 20.1 times earnings and 271% of book, (b) dividend yield based on trailing
four quarters as of December 31, 1997 and stock price as of March 9, 1998 of
2.07%, (c) tangible capital as of December 31, 1997 of 7.46% of assets, (d)
nonperforming assets as of December 31, 1997 equal to .46% of total assets, (e)
return on average assets during the trailing four quarters ended December 31,
1997 of 1.24% and (f) return on average equity during the same period of 13.98%,
with the medians for selected banks and bank holding companies that Danielson
deemed to be comparable to MSBC. The selected institutions included F&M Bancorp,
F&M National Corporation, FCNB Corp., First Charter Corporation, First United
Corporation, LSB Bancshares, Inc., Mason-Dixon Bancshares, Inc., Provident
Bankshares Corp., Sandy Spring Bancorp, Inc., Triangle Bancorp, Inc. and Union
Bankshares Corp. The comparable medians were (a) stock price equal to 21.1 times
earnings and 282% of book, (b) dividend yield of 1.90%, (c) tangible capital of
9.43% of assets, (d) .64% of assets nonperforming, (e) return on average assets
of 1.26% and (f) return on average equity of 12.64%. Danielson also compared
other income, expense, and balance sheet information of such companies with
similar information about MSBC.

Comparable Transaction Analysis. Danielson compared the consideration to be paid
in the merger to the latest twelve months earnings and equity capital of
Ballston with earnings and capital multiples paid in acquisitions of
Mid-Atlantic banks in 1997 and 1998 through the opinion date. Of these, the most
applicable recent transactions included United Bankshares' purchase of First
Patriot Bank, F&M National Corporation's purchases of Peoples Bank of Virginia
and the Bank of Alexandria, Community Bancshares buying County Bank-Chesterfield
and MSBC's purchases of Regency Financial Shares, Inc., Tysons Financial
Corporation and Commerce Bank Corporation. At the time Danielson made its
analysis, the consideration to be paid in the merger was 235% of Ballston's
December 31, 1997 book value and 23.5 times Ballston's earnings in 1997 after
adjustments were made to exclude unusual and one-time revenues and expenses.
This compares to the median multiples of 256% of book value and 18.7 times
earnings for the most applicable comparable acquisitions and 21.2 times earnings
and 275% of book for all Mid-Atlantic bank acquisitions in 1997.

Other Analysis. In addition to performing the analyses summarized above,
Danielson also considered the general market for bank and thrift mergers, the
historical financial performance of Ballston and MSBC, the deposit market shares
of both companies, and the general economic conditions and prospects of those
companies.

      In examining the historical financial performance for Ballston and MSBC,
Danielson utilized publicly-available financial data of Ballston and MSBC from
1988 and 1989, respectively, through December 31, 1997. This analysis included
among other things consideration of asset growth and change, capital growth and
change, revenue and expense ratio analysis and loan and deposit mix change.

      In examining Ballston's market, Danielson utilized branch deposit
information as of June 30, 1997 and adjusted for mergers in process, to
determine that Ballston held a 1.7% deposit market share in Arlington County.
This analysis also showed Ballston to be one of only three locally-owned
community banks operating in this market area. Danielson also utilized available
office space data to establish that Arlington County and Ballston have 26.2
million and 4.2 million square feet of office space available as of June 30,
1996.

      Danielson also considered in its analysis the markets served by MSBC,
which include eleven Virginia counties, four of Virginia's independent cities
and one Maryland county. MSBC does not currently have any presence in Arlington.

      No company or transaction used in the analysis is identical to Ballston or
MSBC. Accordingly, an analyses of the results of the foregoing is not
mathematical; rather it involves complex considerations and judgments concerning
differences in financial and operating characteristics of the companies and
other factors that could affect the public trading values of the company or
companies to which they are being compared.

      The summary set forth above does not purport to be a complete description
of the analyses and procedures performed by Danielson in the course of arriving
at its opinions. The full text of the opinion of Danielson dated as of March 11,
1998, which sets forth assumptions made and matters considered, is attached
hereto as Appendix II of this Proxy Statement/Prospectus. Ballston shareholders
are urged to read this opinion in its entirety. Danielson's opinion is directed
only to the consideration to be received by Ballston shareholders in the Merger
and does not constitute a recommendation to any Ballston shareholder as to how
any such shareholder should vote at the shareholders meeting.

      Ballston has agreed to pay Danielson a transaction fee in connection with
the Merger, a substantial portion of which is contingent upon the consummation
of the Merger. Under the terms of the Danielson agreement, Ballston has agreed
to pay Danielson a transaction fee equal to 0.5% of the aggregate transaction
price, of which approximately 25% has been paid and the remainder is payable
upon closing of the transaction. Danielson has also received a fee of $10,000
for rendering its fairness opinion, which amount will be credited against the
balance of the transaction fee payable to Danielson upon consummation of the
Merger. Ballston has also agreed to reimburse Danielson for its reasonable
out-of-pocket expenses incurred in connection with its engagement and to
indemnify Danielson and its affiliates and their respective partners, directors,
officers, employees, agents, and controlling persons against certain expenses
and liabilities, including liabilities under securities laws. In regard to the
failed AANB Merger, Danielson was paid fees of approximately $13,000.

Conditions to Consummation of the Merger; Waiver

      The Merger will occur only if holders of at least a majority of the
outstanding shares of Ballston Common Stock approve the Merger Agreement.
Consummation of the Merger is subject to the satisfaction of certain other
conditions, including (i) receipt of the approval by the Federal Reserve Board
and the SCC; (ii) representations and warranties of MSBC and Ballston contained
in the Merger Agreement being true and correct on the effective date; (iii)
receipt by MSBC of a letter from each person who is deemed to be an "affiliate"
of Ballston, concerning transactions in the stock of Ballston and MSBC before
and after the Merger; (iv) continued effectiveness of the registration statement

No Solicitation of Transactions

      Pursuant to the Merger Agreement, Ballston and its directors, officers,
employees, representatives or agents may not, directly or indirectly, take any
action to solicit, support or encourage any offer or proposal from any other
person to acquire Ballston or its assets or shares of Ballston Common Stock, or
engage in negotiations with or provide information to such person with respect
to such offer or proposal. In connection with any unsolicited bona fide written
proposal, Ballston may engage in such negotiations or provide information if the
Board of Directors of Ballston concludes, after receipt of legal advice from its
counsel, that their fiduciary duties to the shareholders of Ballston so require.
Ballston will immediately notify MSBC if any such negotiations occur, if such
information is provided, or if such offer or proposal is made, and will keep
MSBC informed of any such negotiations, offers, proposals, or transactions.

Stock Option Agreement

      In connection with the Merger Agreement, MSBC and Ballston entered into a
Stock Option Agreement, dated as of March 11, 1998 (the "Option Agreement").
Specifically, the Option Agreement provides that MSBC shall have the option to
purchase up to 322,275 of the authorized, but unissued, shares of Ballston's
Common Stock at a price of $8.64 per share. The Option Agreement provides that
MSBC has an option to purchase Ballston Common Stock only upon the occurrence of
the following events: (i) Ballston enters into an agreement with a third party
to engage in a merger, consolidation, sale of substantially all of its assets,
or sale of securities representing 20% or more of the voting power of Ballston;
or (ii) a third party acquires beneficial ownership or the right to acquire
beneficial ownership of 25% or more of outstanding Ballston Common Stock. MSBC's
right to exercise the Option Agreement has not been triggered as of the date of
this Proxy Statement/Prospectus.

MSBC's Acquisition Program

      MSBC has expanded its market area and increased its market share through
both internal growth and strategic acquisitions. Since December 31, 1997, MSBC
has acquired approximately $191.6 million in assets and approximately $145.0
million in deposits through two bank acquisitions. On February 28, 1998, MSBC
completed the acquisition of Tysons Financial Corporation, the holding company
of Tysons National Bank, with three offices in Northern Virginia. At March 31,
1998, Tysons Financial Corporation had total assets of $119.5 million and $98.5
million in deposits. Additionally, on March 10, 1998, MSBC completed the
acquisition of Regency Financial Shares, Inc., the holding company of Regency
Bank, with three offices in the Richmond, Virginia area. At March 31, 1998,
Regency Bank had total assets of $81.6 million and $69.2 million in deposits.
Additional opportunities may exist for MSBC to acquire financial institutions or
to acquire assets and deposits that will allow MSBC to enter new markets or
increase market share in existing markets. MSBC may also pursue acquisition
opportunities in strategic markets where its managerial, operational and capital
resources will enhance the performance of acquired institutions and, after the
date of this Proxy Statement/Prospectus, may enter into agreements to acquire
one or more financial institutions. In this regard, acquisitions typically
involve the payment of a premium over book value and market values, and
therefore some dilution of MSBC's book value and net income per common share may
occur in connection with any future transaction.

Exchange Ratio Termination

      The Merger Agreement contains a provision that permits Ballston to
terminate the Merger Agreement if there is a decline in the Average MSBC Share
Price that is not coincidental with a significant decline in the stock prices of
certain financial institutions' holding companies unless MSBC is willing to
increase the consideration it will pay for Ballston Common Stock by adjusting
the Exchange Ratio. Generally, Ballston will have the right to terminate the
Merger Agreement if both (i) the Average MSBC Share Price is less than $24.47
and (ii) the decline is at least 10% greater than the decline of the other
institutions.

      This provision specifically provides that Ballston may terminate the
Merger Agreement during the ten day period commencing on the Determination Date
(defined below) preceding the Effective Date, if both of the following
conditions are satisfied (i) the average share price is less than $24.47; and
(ii) if the First Percentage (defined below) exceeds the Second Percentage
(defined below) by at least ten (10) percentage points.

      If Ballston elects to exercise this termination right, it must give prompt
written notice to MSBC following its election. During the seven day period
beginning when MSBC receives notice from Ballston, MSBC has the option to avoid
a termination of the Merger Agreement by electing to increase the merger
consideration. The increase would occur by adjusting the Exchange Ratio to a
number that would provide shareholders of Ballston with stock of MSBC equal in
market value to $12.04 per share of Ballston Common Stock held by such
shareholders. If MSBC makes this election, it must give prompt written notice to
Ballston of its election and the consideration to be received. As a result, no
termination will occur and the Merger Agreement will otherwise remain in effect
in accordance with its terms.



                                     - 23 -

<PAGE>


      The following terms have the meanings indicated below:

      "Determination Date" means the tenth calendar day prior to the Effective
Date.

      "First Percentage" means the percentage resulting from: (a) taking the
remainder ("First Remainder") obtained by subtracting the Average MSBC Share
Price from $27.19; and (b) dividing the First Remainder by the Average MSBC
Share Price.

      "Second Percentage" means the percentage resulting from: (a) taking the
remainder ("Second Remainder") obtained by subtracting the SNL Southeast Bank
Index reported most recently prior to the last trading day in the measuring
period for calculating the Average MSBC Share Price ("Recent SNL Bank Index")
from the SNL Southeast Bank Index reported most recently prior to or on February
13, 1998; and (b) dividing the Second Remainder by the Recent SNL Bank Index.


Termination

      In addition to terminating the Merger Agreement based upon a decline in
MSBC's common stock price described above, the Merger Agreement may be
terminated at any time prior to the effective date, whether before or after its
approval by the shareholders of Ballston: (i) by mutual consent of MSBC and
Ballston; (ii) by either MSBC or Ballston if any representation or warranty is
breached by the other party or if there has been a material breach by the other
party of any of the covenants or agreements, as set forth in the Merger
Agreement, that has not been cured within 30 days of giving written notice of
the breach; (iii) by either MSBC or Ballston, in the event that the Merger is
not consummated by September 30, 1998; (iv) by either MSBC or Ballston, in the
event the Merger is not approved by the shareholders of Ballston; (v) by either
MSBC or Ballston, in the event the Merger is not approved by the Federal Reserve
Board or the SCC; and (vi) by Ballston, if its Board of Directors concludes,
after receipt of written legal advice from its counsel, that the Board's
fiduciary duties to the Ballston shareholders require the Board to recommend
another acquisition proposal to its shareholders after determining that such
proposal is superior in value to the shareholders to the transaction
contemplated by the Merger Agreement, and Ballston gives at least three business
days prior notice to MSBC of termination.

      In the event of a termination of the Merger Agreement, the Merger
Agreement shall thereafter become void and subject to certain specific
provisions of the Merger Agreement dealing with confidentiality of information
and expenses, and no party shall be relieved or released from any liability
arising out of a breach of any provisions of the Merger Agreement, except as to
the payment of certain expenses by the non-breaching party.

Federal Income Tax Consequences

      MSBC and Ballston have received an opinion from Flippin, Densmore, Morse,
Rutherford & Jessee, A Professional Corporation, counsel for MSBC to the effect
that, for federal income tax purposes:


                                                     - 24 -

<PAGE>

      1. The Merger will constitute a "reorganization" within the meaning of
Section 368(a) of the Code. Ballston and MSBC will each qualify as a "party to a
reorganization" within the meaning of Section 368(b) of the Code.

      2. No gain or loss will be recognized by MSBC or Ballston as a result of
the Merger.

      3. No gain or loss will be recognized by Ballston shareholders as a result
of the exchange of Ballston Common Stock solely for MSBC common stock (including
any fractional share interest) pursuant to the Merger, except that gain or loss
will be recognized on the receipt of cash, if any, received in lieu of a
fractional share of MSBC common stock.

      4. Cash received by a Ballston shareholder in lieu of a fractional share
of MSBC common stock will be treated as having been received as full payment in
exchange for such fractional share pursuant to Section 302(a) of the Code. Such
shareholder will recognize gain or loss equal to the difference between the
amount of cash received and the shareholder's basis in that fractional share,
and such gain or loss will be capital gain or loss if the fractional share would
have been a capital asset in the hands of the shareholder.

      5. A dissenting shareholder who receives solely cash in exchange for his
Ballston Common Stock will be treated as receiving a distribution in redemption
of his Ballston Common Stock, subject to the provisions and limitations of
Section 302 of the Code.

      6. The aggregate tax basis of MSBC common stock (including any fractional
share interest) received in the Merger by Ballston shareholders who exchange
their Ballston Common Stock solely for shares of MSBC common stock will be the
same as the aggregate tax basis of Ballston Common Stock surrendered in exchange
therefor.

      7. The holding period of MSBC common stock received by Ballston
shareholders will include the period during which Ballston Common Stock
surrendered in exchange therefor was held by such Ballston shareholders,
provided the Ballston Common Stock was held as a capital asset on the date of
the exchange.

      The opinion is based on certain customary assumptions and representations
made by duly authorized officers of MSBC and Ballston. The opinion is not
binding on the Internal Revenue Service, any tax authority or any court. No
assurance can be given that a position contrary to that expressed in the opinion
will not be asserted by the Internal Revenue Service or any tax authority or
that such contrary position will not prevail. The opinion does not address all
aspects of federal income taxation that may be relevant to particular holders of
Ballston Common Stock and the opinion may not be applicable to holders of
Ballston Common Stock that are not citizens or residents of the United States or
to holders of options or warrants. The opinion does not address the effect of
any applicable foreign, state, local or other tax laws. Receipt of substantially
the same opinion as of the Merger Effective Date is a condition to consummation
of the Merger.


                                     - 25 -

<PAGE>

      The tax consequences to any particular shareholder may depend on the
shareholder's circumstances. Ballston shareholders are urged to consult their
own tax advisors with regard to foreign, state and local tax consequences.

Exchange of Certificates; Payment for Fractional Shares

      After the Effective Date, each holder of a certificate theretofore
representing outstanding shares of Ballston Common Stock, upon surrender of such
certificate to Registrar and Transfer Company, Post Office Box 1010, Cranford,
New Jersey (which shall act as exchange agent) (the "Exchange Agent"),
accompanied by a letter of transmittal shall be entitled to receive in exchange
therefor a certificate or certificates representing the number of full shares of
MSBC common stock for which shares of Ballston Common Stock theretofore
represented by the certificate or certificates so surrendered shall have been
exchanged as provided plus cash in lieu of any fractional shares. Until so
surrendered, each outstanding certificate which, prior to the Effective Date,
represented Ballston Common Stock will be deemed for all corporate purposes of
MSBC to evidence ownership of the number of full shares of MSBC common stock
into which the shares of Ballston Common Stock represented thereby were
converted, together with a right to cash in lieu of any fractional shares. Until
such outstanding certificates formerly representing Ballston Common Stock are
surrendered, no dividend payable to holders of record of MSBC common stock for
any period as of the date subsequent to the Effective Date shall be paid to the
holder of such outstanding certificates in respect thereof. After the Effective
Date there shall be no further registry of transfer on the records of Ballston
of shares of Ballston Common Stock. If a certificate representing such shares is
presented to the Exchange Agent, it shall be canceled and exchanged for a
certificate representing the shares of MSBC common stock as herein provided.
MSBC will also issue a certificate in exchange for shares evidenced by lost
certificate(s) provided the record owner thereof provides MSBC with such
substantiation, indemnification and security as MSBC should reasonably require.

      Upon surrender of certificates of Ballston Common Stock in exchange for
MSBC common stock, there shall be paid to the record holder of the certificates
of MSBC common stock issued in exchange therefor (i) the amount of dividends
theretofore paid with respect to such full shares of MSBC common stock as of any
date subsequent to the Effective Date which have not yet been paid to a public
official pursuant to abandoned property laws and (ii) at the appropriate payment
date the amount of dividends with a record date after the Effective Date, but
prior to surrender, and payment date subsequent to surrender. No interest shall
be payable with respect to such dividends upon surrender of outstanding
certificates.

      As soon as practicable after the Effective Date, cash (without interest)
will be paid to Ballston shareholders in lieu of the issuance of any fractional
shares in an amount equal to the fraction of a share of MSBC common stock to
which such shareholders would be entitled multiplied by the Average MSBC Share
Price.

Accounting Treatment

      The Merger will be accounted for as a "pooling of interests" under
generally accepted accounting principles.


                                     - 26 -

<PAGE>

Regulatory Approvals

      The Merger is subject to the prior approval of the Board of Governors of
the Federal Reserve System (the "Federal Reserve") under the Bank Holding
Company Act of 1956, as amended (the "BHC Act") and the SCC. All regulatory
approvals have been received.

Interests of Certain Persons in the Merger

      As set forth below, certain members of Ballston's management and Board of
Directors have interests in the Merger in addition to their interests as
shareholders.

      Indemnification; Liability Insurance.  MSBC agrees that for the period of
the relevant statute of limitations but in no event less than six years
following the Effective Date, it shall cause Ballston and any successor thereto
to indemnify and hold harmless any person who has rights to indemnification from
Ballston to the same extent and on the same conditions as such person is
entitled to indemnification pursuant to Ballston's Bylaws 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 Effective Date (regardless of
whether a claim is asserted in connection therewith on or prior to the Effective
Date or thereafter). MSBC shall use its reasonable best efforts to provide
coverage to the officers and directors of Ballston under MSBC's 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
MSBC.

      Employee Benefits. Upon consummation of the Merger, as soon as
administratively practicable, employees of Ballston shall be entitled to
participate in MSBC's pension, severance, benefit and similar plans on the same
terms and conditions as employees of MSBC and its subsidiaries. Employees of
Ballston shall be given full credit for past service with Ballston for purposes
of eligibility and vesting in the MSBC 401(k) plan.

Resales by Affiliates

      The shares of MSBC common stock issued to Ballston's shareholders upon
consummation of the Merger have been registered under the Securities Act, but
such registration does not cover resales by affiliates of Ballston
("Affiliates"). MSBC common stock received and beneficially owned by those
shareholders who are deemed to be Affiliates may be resold without registration
as provided for by Rule 145 under the Securities Act, or as otherwise permitted.
The term "Affiliate" is defined to include any person who, directly or
indirectly, controls, or is controlled by, or is under common control with
Ballston at the time the Merger Agreement is submitted for approval by a vote of
holders of Ballston's Common Stock. Generally, this definition includes
executive officers, directors and 10% shareholders of Ballston and The Bank.
Each Affiliate who desires to resell MSBC common stock received in the Merger
must sell such MSBC common stock either (i) pursuant to an effective
registration statement under the Securities Act; (ii) in accordance with the
applicable provisions of Rule 145 under the Securities Act; or (iii) in a
transaction which, in the opinion of counsel for such affiliates or as described
in a "no-action" or interpretive letter from the staff of the Securities and
Exchange Commission, in each case reasonably satisfactory in form and substance
to MSBC, to the effect that such resale is exempt from the registration
requirements of the Securities Act.

                                     - 27 -

<PAGE>
      Rule 145(d) requires that persons deemed to be affiliates resell their
MSBC common stock pursuant to certain of the requirements of Rule 144 under the
Securities Act if such MSBC common stock is sold within the first year after the
receipt thereof. After one year, if such person is not an affiliate of MSBC and
MSBC is current in the filing of its periodic securities law reports, a former
affiliate of Ballston may freely resell the MSBC common stock received in the
Merger without limitation. After two years from the issuance of the MSBC common
stock, if such person is not an affiliate of MSBC at the time of sale or for at
least three months prior to such sale, such person may freely resell such MSBC
common stock, without limitation, regardless of the status of MSBC's periodic
securities law reports.

      Commission guidelines regarding qualifying for the pooling-of-interests
method of accounting also limit sales of stock of the acquiring company and
acquired company by affiliates of either company in a business combination.
Commission guidelines also indicate that the pooling-of-interests method of
accounting will generally not be challenged on the basis of sales by affiliates
of the acquired or acquiring company if they do not dispose of any shares of the
corporation whose shares they own or shares of a corporation whose shares they
receive in connection with a merger during the period beginning 30 days before
the Merger and ending when financial results covering at least 30 days of
post-merger operations of the combined operations have been published.

      Each Affiliate has delivered to MSBC a letter pursuant to which such
person agreed, among other things, not to offer to sell, transfer or otherwise
dispose of any of the shares of MSBC common stock distributed to him or her
pursuant to the Merger except (i) with respect to Affiliates of Ballston, in
compliance with Rule 145 under the Securities Act, or in a transaction that, in
the opinion of counsel reasonably satisfactory to MSBC, is otherwise exempt from
the registration requirements of the Securities Act, and (ii) with respect to
Affiliates of each of Ballston and MSBC, in compliance with Commission
guidelines regarding qualifying for pooling-of-interests accounting treatment.
MSBC may place restrictive legends on certificates representing MSBC common
stock issued to all persons who are deemed to be "Affiliates" under Rule 145.
The certificates of MSBC common stock issued to Affiliates in the Merger may
contain an appropriate restrictive legend, and appropriate stop transfer orders
may be given to the transfer agent for such certificates.

Rights of Dissenting Shareholders

      Under Section 262 of the DGCL, a copy of which is included as Appendix III
to this Proxy Statement/Prospectus, each holder of Ballston Common Stock will be
entitled to dissent and demand an appraisal of the "fair value" of Ballston
Common Stock held thereby if, prior to the vote at the Ballston Meeting, such
Ballston Shareholder files with Ballston a written demand for appraisal and does
not vote in favor of the Merger. Within ten days after the Effective Date, MSBC
shall notify each Ballston shareholder exercising appraisal rights in compliance
with Section 262 of the date that the Merger has become effective. At any time
within 60 days after the Effective Date, any shareholder shall have the right to
withdraw demand for appraisal and to accept the terms offered upon the Merger. A
written demand for appraisal should be sent to Ballston Bancorp, Inc., 1667 K
Street, N.W., Suite 700, Washington, D.C. 20006, Attn: Brian D. Alprin,
Secretary. Any Ballston shareholder who fails to comply with the requirements
described above will be bound by the terms of the Merger.


                                     - 28 -

<PAGE>

      Within 120 days after the Effective Date, MSBC or any Ballston shareholder
who has perfected appraisal rights in accordance with Section 262 of the DGCL
may file a petition with the Delaware Court of Chancery (the "Court") demanding
a determination of the value of the stock of all such shareholders. If no
petition is filed within such time, the dissenting shareholders' appraisal
rights shall terminate. At the hearing on such petition, the Court shall
determine the Ballston shareholders who have complied with Section 262 and who
have become entitled to appraisal rights. The Court may require that the
shareholders submit their certificates of stock, if any, to the Register in
Chancery for notation thereon of the pendency of the appraisal proceedings, and
if any shareholder fails to comply with such direction, the Court may dismiss
the proceedings as to such shareholder. MSBC has informed Ballston that it does
not intend to file such a petition with the Court in the event that any Ballston
shareholder has perfected appraisal rights.

      After determining the shareholders entitled to an appraisal, the Court
shall appraise the shares as to their fair value. In determining their fair
value, the Court shall take into account all relevant factors exclusive of any
element of value arising from the accomplishment or expectation of the Merger.
The Court shall direct the payment of the fair value of the shares, together
with interest, if any, by MSBC to the shareholders entitled to such payment. The
costs of the proceedings may be determined by the Court and assessed against
either MSBC or the shareholders, or both. The value determined by the Court may
be the same as, more than, or less than the merger consideration Ratio to be
paid pursuant to the Merger Agreement.

      The Delaware Supreme Court has stated that "proof of value by any
techniques or methods which are generally considered acceptable in the financial
community and otherwise admissible in court" should be considered in the
appraisal proceedings. In addition, Delaware courts have decided that the
statutory appraisal remedy, depending on factual circumstances, may or may not
be a dissenter's exclusive remedy. The Court will also determine the amount of
interest, if any, to be paid upon the amounts to be received by persons whose
shares of Ballston Common Stock have been appraised. The costs of the action may
be determined by the Court and taxed upon the parties as the Court deems
equitable in the circumstances. The Court may also order that all or a portion
of the expenses incurred by any holder of shares of Ballston Common Stock in
connection with an appraisal, including, without limitation, reasonable
attorneys' fees and the fees and expenses of experts utilized in the appraisal
proceeding, be charged pro rata against the value of all of the shares of
Ballston Common Stock entitled to appraisal.


                                     - 29 -

<PAGE>

      From and after the Effective Date, no Ballston shareholder who has
demanded appraisal rights is entitled to vote such stock for any purpose or to
receive payment of any dividends or other distributions on the stock, provided,
however, that if no petition for an appraisal is filed within the allotted time
or if such shareholder withdraws his demand for appraisal within 60 days of the
Effective Date or, thereafter, with written approval of Ballston, then the right
of appraisal shall cease.

      The foregoing summary of the rights of shareholders requesting appraisal
contains material information relating to the exercise of appraisal rights but
does not purport to be a complete statement of the procedures to be followed by
Ballston shareholders desiring to exercise their rights requesting appraisal.
The preservation and exercise of appraisal rights are conditioned on strict
adherence to the applicable provisions of Section 262 of the DGCL. Each Ballston
shareholder desiring to exercise appraisal rights should refer to Section 262 of
the DGCL for a complete statement of the shareholder's rights and the steps
which must be followed in connection with the exercise of those rights.

      For further information relating to the exercise of appraisal rights, see
Appendix III to this Proxy Statement/Prospectus.

Description of MSBC Capital Stock

      MSBC is presently authorized to issue 20,000,000 shares of common stock,
par value $5.00 per share, and 1,000,000 shares of preferred stock. As of March
31, 1998, there were 13,330,991 shares of MSBC common stock issued and
outstanding and no shares of preferred stock were outstanding. MSBC common stock
is traded in the over-the-counter market and quoted on the Nasdaq National
Market under the symbol "MSBC." At March 31, 1998, there were approximately
3,665 holders of record.

      The following summary description of capital stock of MSBC is qualified in
its entirety by reference to MSBC's Articles of Incorporation, a copy of which
has been incorporated by reference as an exhibit to the Registration Statement.

      Common Stock

      Holders of MSBC common stock are entitled to one vote per share on each
matter to be voted upon by the shareholders. Directors are elected by a vote of
the holders of MSBC common stock. Dividends may be paid to the holders of MSBC
common stock when, as and if declared by the board of directors out of funds
legally available for such purposes. The principal source of funds for dividend
payments is dividends received from the MainStreet Banks and the Trust Company.
Payment of dividends to MSBC by the Banks and Trust Company, without prior
regulatory approval, is also subject to various state and federal regulatory
limitations. In addition, MSBC's ability to pay dividends may be limited by its
obligations under a trust preferred offering (the "Trust Preferred Offering")
described below. Holders of common stock have no conversion, redemption,
cumulative voting or preemptive rights. All outstanding shares of MSBC common
stock are, and the shares of MSBC common stock to be issued in the Merger will
be, when issued, duly and validly issued, fully paid and nonassessable.

                                     - 30 -

<PAGE>

      Preferred Stock

      The board of directors, without further action by the shareholders, is
authorized to designate and issue in series preferred stock and to fix as to any
series the dividend rate, redemption prices, preferences on dissolution, the
terms of any sinking fund, conversion rights, voting rights, and any other
preferences or special rights and qualifications. The board of directors without
shareholder approval can issue preferred stock with voting and conversion rights
which would adversely affect the voting power of the common stockholders, or
discourage or make more difficult an attempt to acquire control of MSBC. MSBC's
board of directors has designated a series of 1,000,000 shares of series A
preferred stock, no shares of which have been issued. The series A preferred
stock was created in connection with the shareholder rights agreement described
below.

      MSBC Preferred Share Rights Plan

      Pursuant to a rights agreement (the "MSBC Preferred Share Rights Plan")
dated as of January 18, 1990, MSBC distributed as a dividend one right (the
"MSBC Right" or "MSBC Rights") for each outstanding share of MSBC common stock.
The number of MSBC Rights associated with each share of MSBC common stock
outstanding as of June 30, 1993 was adjusted proportionately for the
five-for-four stock split effective July 30, 1993 and the two-for-one stock
split effective March 15, 1996. Each MSBC Right entitles the holder to buy
fractional shares of Participating Cumulative Preferred Stock, Series A, par
value $5.00 per share, at an exercise price of $24, subject to adjustment. The
MSBC Rights will become exercisable only if a person or group acquires or
announces a tender offer for 15% or more of the outstanding MSBC common stock.
When exercisable, MSBC may issue a share of MSBC common stock in exchange for
each MSBC Right other than those held by such person or group. If a person or
group acquires 30% or more of the outstanding MSBC common stock, each MSBC Right
will entitle the holder, other than the acquiring person, upon payment of the
exercise price, to acquire Preferred Stock or, at the option of MSBC, MSBC
common stock, having a market value equal to twice the MSBC Rights exercise
price. If MSBC is acquired in a merger or other business combination or if 50%
of its earnings power is sold, each MSBC Right will entitle the holder, other
than the acquiring person, to purchase securities of the surviving company
having a market value equal to twice the MSBC Rights exercise price. The MSBC
Rights will expire on January 18, 2000, and may be redeemed by MSBC at any time
prior to the tenth day after an announcement that a 10% position has been
acquired, unless such time period has been extended by the board of directors.

      Until such time as a person or group acquires or announces a tender offer
for 15% or more of the MSBC common stock, (i) the MSBC Rights will be evidenced
by the MSBC common stock certificates and will be transferred with and only with
such MSBC common stock certificates, and (ii) the surrender for transfer of any
certificate for MSBC common stock will also constitute the transfer of the MSBC
Rights associated with the MSBC common stock represented by such certificate.
MSBC Rights may not be transferred, directly or indirectly (i) to any person or
group that has acquired, or obtained the right to acquire, beneficial ownership
of 10% or more of the MSBC Rights (an "Acquiring Person"), (ii) to any person in
connection with a transaction in which such person becomes an Acquiring Person
or (iii) to any affiliate or associate of any such person. Any MSBC Right that
is the subject of a purported transfer to any such person will be null and void.

                                     - 31 -

<PAGE>

      The MSBC Rights can be expected to have certain anti-takeover effects if
an acquisition transaction not approved by the board of directors is proposed by
a person or group. In such event, the MSBC Rights will cause substantial
dilution to any person or group that acquires more than 15% of the outstanding
shares of MSBC common stock if certain events thereafter occur without the MSBC
Rights having been redeemed. Because of these provisions, it is unlikely that
any person or group will propose an acquisition transaction that is not approved
by the board of directors. Thus, the MSBC Rights could have the effect of
discouraging acquisition transactions not approved by the board of directors.
The MSBC Rights do not interfere with any merger or other business combination
approved by the board of directors and shareholders because the MSBC Rights are
redeemable with the concurrence of a majority of the "Continuing Directors,"
defined as directors in office when the MSBC Preferred Share Rights Plan was
adopted or any person added thereafter to the Board with the approval of the
Continuing Directors.

      The foregoing description of the MSBC Preferred Share Rights Plan does not
purport to be complete and is qualified in its entirety by reference to the
terms of the MSBC Preferred Share Rights Plan, which is more fully described on
Form 8-K filed January 19, 1990, which is incorporated herein by reference.

Trust Preferred Offering

      In November, 1997, MSBC created a special purpose subsidiary, MSBC Capital
Trust I, to issue approximately $50 million of trust preferred securities. The
issuance of these securities was completed on November 19, 1997, and the
proceeds were used to purchase approximately $50 million of junior subordinated
debentures issued by MSBC. The proceeds received by MSBC from the sale of the
junior subordinated debentures are expected to be used to increase its capital
to support recent and pending acquisitions and for other general corporate
purposes. MSBC has guaranteed the trust preferred securities and is obligated
under the junior subordinated debentures. Accordingly, no dividend may be paid
to holders of MSBC common stock until interest payments are made under the
junior subordinated debentures.

Comparative Rights of Shareholders

      There are significant differences between the corporation laws of Virginia
and Delaware and the organizational documents of MSBC and Ballston. As a
Virginia corporation, MSBC is subject to the provisions of the Virginia Stock
Corporation Act (the "VSCA"). Ballston is a Delaware corporation and is
therefore subject to the DGCL. Shareholders of Ballston, whose rights are
governed by Ballston's certificate of incorporation ("Ballston's Certificate")
and Ballston's bylaws ("Ballston Bylaws") and by the DGCL will become
shareholders of MSBC upon consummation of the Merger. Accordingly, the rights of
the Ballston shareholders as shareholders of MSBC will then be governed by the
MSBC articles of incorporation ("MSBC Articles"), MSBC bylaws ("MSBC Bylaws"),
and the VSCA.


                                     - 32 -

<PAGE>


      The VSCA and the DGCL differ in several respects. It is not practical to
summarize all of such differences in this Proxy Statement/Prospectus, but some
of the principal differences which could affect the rights of shareholders
materially are discussed below. This summary is qualified in its entirety by
reference to the articles or certificate of incorporation and bylaws of each
corporation and the VSCA and the DGCL.

Authorized Capital. MSBC Articles authorizes the issuance of (i) 20,000,000
shares of common stock, of which 13,330,991 shares, $5.00 par value, were issued
and outstanding as of March 31, 1998 and (ii) 1,000,000 shares of preferred
stock, without par value, of which no shares were issued and outstanding as of
March 31, 1998. MSBC 's Articles authorize the MSBC board of directors (the
"MSBC Board"), without shareholder approval, to fix the preferences, limitations
and relative rights of the preferred stock and to establish series of such
preferred stock and determine the variations between each series. If any shares
of preferred stock are issued, the rights of holders of MSBC common stock would
be subject to the rights and preferences conferred to holders of such preferred
stock. In addition, the preferred stock could be used in a manner which would
discourage or make more difficult an attempt to acquire control of MSBC. See "--
MSBC Rights Agreement."

      Ballston's Certificate authorizes the issuance of (i) 3,000,000 shares of
common stock, of which 1,619,474 shares, $.20 par value, were issued and
outstanding as of March 31, 1998 and 500,000 shares of serial preferred stock,
$.20 par value, of which no shares were issued and outstanding as of March 31,
1998. Ballston's Certificate authorizes the Ballston Board, without shareholder
approval, to fix the preferences, limitations and relative rights of the
preferred stock and to establish series of such preferred stock and determine
the variations between each series. Similar to the MSBC Articles, if any shares
of preferred stock are issued, the rights of holders of Ballston Common Stock
would be subject to the rights and preferences conferred to holders of such
preferred stock.

      The holders of both MSBC common stock and Ballston Common Stock have one
vote for each share held on any matter presented for consideration by the
shareholders. Neither the holders of MSBC common stock nor Ballston Common Stock
are entitled to cumulative voting in the election of directors.

Preemptive Rights. The common stock shareholders of MSBC and Ballston do not
have preemptive rights, and each of the MSBC Board and the Ballston Board has
the authority to issue additional shares without first obtaining the approval of
existing shareholders and without first offering such shares to existing
shareholders for purchase. Following the proposed merger, MSBC common stock will
continue to be available for issuance by the MSBC Board when and as the MSBC
Board determines, for the purpose of raising capital, in acquiring other
businesses, and for other appropriate purposes.


                                     - 33 -

<PAGE>

Directors; Vacancies and Removal of Directors. Under the VSCA, the number of
directors of a corporation may be fixed in the articles of incorporation or
bylaws of a corporation. The MSBC Bylaws provide that the MSBC Board shall
consist of 12 persons. All of the MSBC directors are elected each year. Any
vacancy occurring on the MSBC Board, including a vacancy resulting from an
increase in the number of directors, may be filled by the affirmative vote of a
majority of the remaining directors, though less than a quorum of the MSBC
Board. However, the VSCA provides that, when the bylaws fix the number of
directors, the Board may only increase or decrease that number by 30% or less
without shareholder action. Directors so chosen shall hold office for a term
expiring at the next following annual meeting of shareholders at which directors
are elected. No decrease in the number of directors constituting the MSBC Board
shall shorten the term of any incumbent director. Subject to the rights of the
holders of any preferred stock then outstanding, any director may be removed by
the affirmative vote of the holders of at least two-thirds of outstanding voting
shares.

      Under the DGCL, the number of directors of a corporation, absent a
provision in the certificate to the contrary, may be fixed by, or in the manner
provided by, the bylaws. The Ballston Bylaws provide that the Ballston Board
shall consist of not less than one nor more than 25 persons. The Ballston Board
currently consists of 7 persons, which all are elected each year. Any vacancy
occurring on the Ballston Board, other than a vacancy resulting from an increase
of more than five persons, may be filled by the affirmative vote of a majority
of the remaining directors, though less than a quorum of the Ballston Board. In
addition, any vacancy, including one created from an increase in the number of
directors, may be filled at a meeting called for such purpose, by vote of the
shareholders. Directors so chosen shall hold office for a term expiring at the
next following annual meeting of shareholders at which directors are elected.
Subject to the rights of the holders of any preferred stock outstanding, any
director may be removed by the affirmative vote of the holders of at least a
majority of outstanding voting shares.

Power to Call Special Shareholders' Meetings. Under the VSCA, a special meeting
of shareholders may be called by the board of directors or by any other person
authorized to do so in the certificate of incorporation or the bylaws. The MSBC
Bylaws provide that a special meeting of shareholders may be called by the
Chairman, the Vice-Chairman, the President or a majority of the directors.

       Under the DGCL, a special meeting of shareholders may be called by the
board of directors or by any other person authorized to do so in the certificate
of incorporation or the bylaws. The Ballston Bylaws provide that special
meetings of shareholders may be called by the Ballston Board, by the Chairman of
the Ballston Board, or, if there is none, by the President. Shareholders are not
permitted to call a special meeting or to require that the Board call a special
meeting of shareholders.


                                     - 34 -

<PAGE>



Director Nomination. MSBC's Bylaws provide that any nomination for director made
by a shareholder must be made in writing to the Secretary of MSBC not less than
90 days prior to the meeting of shareholders at which directors are to be
elected. Any such shareholder's notice shall include (i) the name and address of
the shareholder and of each person to be nominated, (ii) a representation that
the shareholder is a holder of record of stock of MSBC entitled to vote at such
meeting and intends to appear in person or by proxy at the meeting to nominate
each person specified, (iii) a description of all arrangements or understandings
between the shareholder and each nominee and any other person (naming such
person) pursuant to which the nomination is made by the shareholder, (iv) such
other information regarding each nominee as would be required to be included in
a proxy statement filed pursuant to the proxy rules of the SEC had the nominee
been nominated by the Board, and (v) the consent of each nominee to serve as a
director of MSBC if so elected. There is no requirement in the MSBC Articles or
MSBC Bylaws that directors of MSBC own any capital stock of MSBC. There are also
no residency or meeting attendance requirements applicable to directors of MSBC.

      The Ballston Bylaws in respect to nominations are substantially similar to
MSBC Bylaws except that any nomination for director made by a shareholder must
be made in writing to the Secretary of Ballston not later than the close of
business on the tenth day following the date on which notice of such meeting is
first given to shareholders. Neither the Ballston Certificate nor the Ballston
Bylaws require directors of Ballston to own any capital stock of Ballston, nor
do they impose residency or meeting attendance requirements.




Shareholder Proposals. MSBC's Bylaws provide that at any meeting of shareholders
of MSBC, only business that is properly brought before the meeting may be
presented to and acted upon by the shareholders. To be properly brought before
the meeting, business must be brought (a) by or at the direction of the Board of
Directors or (b) by a shareholder who has given written notice of business he
expects to bring before the meeting to the Secretary of MSBC by December 1 of
the year preceding the meeting. A shareholder's notice to the Secretary shall
set forth as to each matter the shareholder proposes to bring before the meeting
(a) a brief description of the business to be brought before the meeting and the
reasons for conducting such business at the meeting, (b) the name and address,
as they appear on MSBC's books, of the shareholder proposing such business, (c)
the class and number of shares of MSBC's stock beneficially owned by the
shareholder, and (d) any material interest of the shareholder in such business.
No business shall be conducted at a meeting of the shareholders except in
accordance with the procedures set forth in MSBC Bylaws.

      Ballston's Bylaws in respect to shareholder proposals are substantially
similar to MSBC Bylaws except that written notice by a shareholder that wishes
to bring business before a meeting must be received by the Secretary not later
than the close of business on the tenth day following the date on which notice
of such meeting is first given to shareholders.

Shareholder Inspection Rights; Shareholder Lists. Under the VSCA, the
shareholder of a Virginia corporation is entitled to inspect and copy certain
books and records including the articles of incorporation and bylaws of the
corporation if he or she gives the corporation written notice of his or her
demand at least five business days before the date on which he or she wishes to
inspect and copy. The shareholder of a Virginia corporation is entitled to
inspect and copy certain other books and records, including a list of
shareholders, minutes of any meeting of the board of directors and accounting
records of the corporation, if (i) the shareholder has been a shareholder of
record for at least 6 months immediately preceding his or her written demand or
is the holder of at least 5% of the corporation's outstanding shares, (ii) the
shareholder's demand is made in good faith and for a proper purpose, (iii) the
shareholder describes with reasonable particularity the purpose of the request
and the records desired to be inspected and (iv) the records are directly
connected with the stated purpose, and if the shareholder gives the corporation
written notice of his or her demand at least five business days before the date
on which he or she wishes to inspect and copy. The VSCA also provides that a
corporation shall make available for inspection by any shareholder during usual
business hours, at least 10 days before each meeting of shareholders, a complete
list of the shareholders entitled to vote at such meeting.


                                     - 35 -

<PAGE>

      As permitted under the DGCL, the Ballston Bylaws permit any shareholder,
in person or by attorney or other agent, upon written demand stating the purpose
thereof, to examine, in person or by agent or attorney, at any reasonable time
or times, for any proper purpose, Ballston's books and records of accounts,
minutes and record of shareholders, and to make extracts therefrom.

Shareholder Voting. The VSCA generally requires the approval of a majority of a
corporation's board of directors and the holders of more than two-thirds of all
the votes entitled to be cast thereon by each voting group entitled to vote on
most amendments to the articles of incorporation, any plan of merger or
consolidation, any plan of share exchange, or any sale of substantially all of
the assets of a corporation not in the ordinary course of business. The VSCA
does permit such an amendment or transaction to be approved by as few as a
majority of the votes cast, if the articles of incorporation so state. The VSCA
does not require a shareholder vote of the surviving corporation in a share
exchange or in a merger (unless the corporation provides otherwise in its
articles of incorporation) if (i) the merger agreement does not amend the
existing certificate of incorporation; (ii) each share of the surviving
corporation outstanding before the merger is an identical outstanding share
after the merger; and (iii) the number of shares to be issued by the surviving
corporation in the merger does not exceed directly, or upon conversion thereof,
20% of the common stock outstanding immediately prior to the merger. In
addition, the VSCA also specifies additional voting requirements for Affiliated
Transactions and transactions that would cause an acquiring person's voting
power to meet or exceed specified thresholds, as discussed hereunder,
"Anti-Takeover Provisions."

       Under the DGCL, mergers and consolidations generally require the approval
of the holders of a majority of the capital stock entitled to vote thereon. The
DGCL does not require a shareholder vote of the surviving corporation in a
merger (unless the corporation provides otherwise in its certificate of
incorporation) if (i) the merger agreement does not amend the existing
certificate of incorporation; (ii) each share of the surviving corporation
outstanding before the merger is an identical outstanding or treasury share
after the merger; and (iii) the number of shares to be issued by the surviving
corporation in the merger does not exceed directly, or upon conversion thereof,
20% of the common stock outstanding immediately prior to the merger. In
addition, the DGCL also specifies additional voting requirements for
transactions that would cause an acquiring person's voting power to meet or
exceed specified thresholds. However, such provisions under the DGCL are not
applicable to Ballston. See "Anti-Takeover Provisions."


                                     - 36 -

<PAGE>

Anti-Takeover Provisions. In addition to the Shareholder's Rights Plan created
by MSBC, as discussed hereunder, certain provisions of the VSCA may discourage
an attempt to acquire control of MSBC.

      The VSCA contains provisions governing "Affiliated Transactions." These
provisions, with several exceptions discussed below, require approval of
material acquisition transactions between a Virginia corporation and any holder
of more than 10% of any class of its outstanding voting shares (an "Interested
Stockholder") by the holders of at least two-thirds of the remaining voting
shares. Affiliated Transactions include mergers, share exchanges, material
dispositions of corporate assets not in the ordinary course of business, any
dissolution of the corporation proposed by or on behalf of an Interested
Stockholder, or any reclassification, including a reverse stock split,
recapitalization, or merger of the corporation with its subsidiaries which
increases the percentage of voting shares owned beneficially by an Interested
Stockholder by more than 5%.

      For three years following the time that an Interested Stockholder becomes
an owner of 10% of the outstanding voting shares, a Virginia corporation cannot
engage in an Affiliated Transaction with such Interested Stockholder without
approval of two-thirds of the voting shares other than those shares beneficially
owned by the Interested Stockholder, and majority approval of the "Disinterested
Directors." A Disinterested Director is a member of the MSBC Board who was (i) a
member on the date on which an Interested Stockholder became an Interested
Stockholder and (ii) recommended for election by, or was elected to fill a
vacancy and received the affirmative vote of, a majority of the Disinterested
Directors then on the Board. At the expiration of the three year period, the
statute requires approval of Affiliated Transactions by two-thirds of the voting
shares other than those beneficially owned by the Interested Stockholder.

      The principal exceptions to the special voting requirement apply to
transactions proposed after the three year period has expired and require either
that the transaction be approved by a majority of the corporation's
Disinterested Directors or that the transaction satisfy the fair-price
requirements of the statute. In general, the fair-price requirement provides
that in a two-step acquisition transaction, the Interested Stockholder must pay
the shareholders in the second step either the same amount of cash or the same
amount and type of consideration paid to acquire the Virginia corporation's
shares in the first step.

      None of the foregoing limitations and special voting requirements applies
to a transaction with an Interested Stockholder whose acquisition of shares
making such a person an Interested Stockholder was approved by a majority of the
Virginia corporation's Disinterested Directors.

      These provisions were designed to deter certain takeovers of Virginia
corporations. In addition, the statute provides that, by affirmative vote of a
majority of the voting shares other than shares owned by any Interested
Stockholder, a corporation can adopt an amendment to its articles of
incorporation or bylaws providing that the Affiliated Transactions provisions
shall not apply to the corporation. MSBC has not "opted out" of the Affiliated
Transactions provisions.

      Virginia law also provides that shares acquired in a transaction that
would cause the acquiring person's voting strength to meet or exceed any of the
three thresholds (20%, 331/3% or 50%) have no voting rights unless granted by a
majority vote of shares not owned by the acquiring person. This provision
empowers an acquiring person to require the Virginia corporation to hold a
special meeting of shareholders to consider the matter within 50 days of its
request.

      The Ballston Bylaws contain certain provisions that may limit shareholder
voting rights. These provisions provide for noncumulative voting for directors
and limit the calling of special meetings. In addition, certain provisions under
the DGCL may be deemed to have an anti-takeover effect. However, because
Ballston's Common Stock is neither traded on a national securities market nor
Nasdaq, nor is the Ballston Common Stock held of record by more than 2,000
shareholders, such provisions of the DGCL are not applicable to Ballston.

Shareholder Rights Agreement. MSBC has issued the MSBC Rights and is party to
the MSBC Preferred Share Rights Plan. The MSBC Rights have certain anti-takeover
effects and will cause substantial dilution to a person or a group that attempts
to acquire MSBC on terms not approved by the MSBC board. See "Description of
MSBC Capital Stock - MSBC Rights Plan." The Ballston Board has not adopted a
shareholders rights plan.

Amendment of Articles or Certificate and Bylaws.  The VSCA generally requires
the approval of a majority of a corporation's board of directors and the holders
of more than two-thirds of all the votes entitled to be cast thereon by each
voting group entitled to vote on most amendments to the articles of
incorporation. The VSCA does permit such an amendment or transaction to be
approved by as few as a majority of the votes cast, if the articles of
incorporation so state. The VSCA and MSBC's Bylaws provide, in most cases, that
the MSBC board of directors may, by a majority vote, amend its bylaws.

      Under the DGCL, the certificate of incorporation may be amended if the
amendment is adopted by the board and is approved by an affirmative vote of the
holders of a majority of the outstanding stock entitled to vote on the amendment
by each voting group entitled to vote hereon. There are no provisions in
Ballston's Certificate which modify the statutory requirements for amendment of
the certificate. Under the DGCL, the bylaws may be amended only by the
shareholders, unless the corporation's certificate of incorporation also confers
the power to amend the bylaws on the directors. As permitted under the DGCL,
Ballston's Certificate authorizes the Ballston Board to adopt, amend or repeal
the Ballston Bylaws. The Ballston Bylaws may be amended by action of a majority
of the Ballston Board or by a vote of the holders of 60% of the issued and
outstanding Ballston Common Stock. The stockholders of Ballston may provide that
certain Bylaws may not be amended, altered or repealed except by a specified
percentage of interest of the stockholders or of a particular class of
stockholders.

Director Liability and Indemnification. The VSCA provides that in any proceeding
brought by or in the right of a corporation or brought by or on behalf of
shareholders of the corporation, the damages assessed against an officer or
director arising out of a single transaction, occurrence or course of conduct
may not exceed the lesser of (i) the monetary amount, including the elimination
of liability, specified in the articles of incorporation or, if approved by the
shareholders, in the bylaws as a limitation on or elimination of the liability
of the officer or director, or (ii) the greater of (a) $100,000 or (b) the
amount of cash compensation received by the officer or director from the
corporation during the twelve months immediately preceding the act or omission
for which liability was imposed. The liability of an officer or director is not
limited under the VSCA or a corporation's articles of incorporation and bylaws
if the officer or director engaged in willful misconduct or a knowing violation
of the criminal law or of any federal or state securities law. The MSBC Articles
eliminate officers and directors liability for monetary damages and maximize
indemnification, except in cases of willful misconduct or knowing violation of
criminal or securities law.

      Under the DGCL, a corporation's certificate of incorporation may contain a
provision eliminating or limiting the personal liability of directors to the
corporation or its shareholders for monetary damages for breach of fiduciary
duty as a director, but such provision may not eliminate or limit the liability
of a director for (i) any breach of the director's duty of loyalty to the
corporation or its shareholders, (ii) acts or omissions not in good faith or
which involve intentional misconduct or a knowing violation of law, (iii) wilful
or negligent payment of unlawful dividends or stock purchases or redemptions, or
(iv) any transaction from which the director derived an improper personal
benefit. The Ballston Certificate provides, to the fullest extent permitted by
the DGCL, that a director shall not be liable to the corporation or its
shareholders for monetary damages for a breach of fiduciary duty.

      The provisions of the VSCA and the DGCL are substantially similar with
respect to indemnification of officers and directors. Under the VSCA and DGCL, a
corporation may indemnify any officer or director who was or is a party to any
action, suit, or proceeding by reason of the fact that he is or was a director
or officer of the corporation by, among other things, a majority vote of a
quorum consisting of directors who were not parties to such action, suit, or
proceeding, provided that such officer or director acted in good faith and in a
manner he reasonably believed to be in or not opposed to the best interests of
the corporation.

      The Ballston Bylaws provide for indemnification of officers and directors
to the fullest extent permitted by the DGCL. The Ballston Bylaws also provide
for the advance of expenses incurred by a director or officer in defending a
proceeding, subject to an undertaking by such director or officer to repay such
amount should it be determined that he is not entitled to be indemnified by
Ballston. These provisions are substantially similar to provisions of the MSBC
Articles.

Dividends and Distributions. The VSCA generally provides that a corporation may
make distributions to its shareholders unless, after giving effect to the
distribution, (i) the corporation would not be able to pay its debts as they
become due in the usual course of business or (ii) the corporation's total
assets would be less than the sum of its total liabilities plus (unless the
articles of incorporation permit otherwise, which MSBC Articles do not) the
amount that would be needed, if the corporation were to be dissolved at the time
of the distribution, to satisfy the preferential rights upon dissolution of
shareholders whose preferential rights are superior to those receiving the
distribution.


                                     - 39 -

<PAGE>

      The DGCL generally allows dividends to be paid out of surplus of the
corporation or, if there is no surplus, out of the net profits of the
corporation for the current fiscal year or the prior fiscal year. The directors
of a Delaware corporation are prohibited from making distributions to
shareholders except in the manner provided by the DGCL. In case of any wilful or
negligent violation of the provisions of the DGCL governing distributions, the
directors under whose administration the violation occurred (except for those
directors who dissented) are, for a period of six years, jointly and severally
liable to the corporation and, in the event of the corporation's insolvency or
dissolution, to its creditors for the full amount of the distribution unlawfully
made.

      In addition to the above limitations set forth in the VSCA, there are
various regulatory requirements which are applicable to bank holding companies.
MSBC relies primarily on the ability of its subsidiaries to pay dividends to
MSBC in order for it, in turn, to pay dividends to MSBC shareholders. The
dividends payable by MSBC banking subsidiaries are dependent upon their earnings
and profitability and must be in compliance with certain federal and state
banking law requirements. Following consummation of the proposed Merger,
dividends received by MSBC's shareholders will continue to be dependent upon the
payment of dividends by its banking subsidiaries. Also, MSBC has senior
liabilities pursuant to guarantees of the Junior Subordinated Debentures and
Capital Securities of MainStreet Capital Trust I. See "Description of Capital
Stock of MSBC."


Liquidation Rights. The VSCA generally provides that a corporation's board of
directors may propose dissolution for submission to shareholders and that to be
authorized, the dissolution must be approved by the holders of more than
two-thirds of all votes entitled to be cast on the proposal, unless the articles
of incorporation of the corporation require a greater or lesser vote. There are
no provisions in the MSBC's Articles which modify the statutory requirements for
dissolution under the VSCA.

      The DGCL generally provides that a corporation's board of directors may
propose dissolution for submission to shareholders and that a majority of the
whole board of directors must approve such resolution to be authorized. The
dissolution also must be approved by the holders of a majority of the
outstanding shares entitled to vote on the proposal. Dissolution of a
corporation may also be authorized without action of the directors if all the
shareholders entitled to vote thereon shall consent in writing. There are no
provisions in the Ballston's Certificate or Ballston's Bylaws which would modify
the statutory requirements for dissolution under the DGCL.

Appraisal Rights and Rights of Dissenting Shareholders. Under both the VSCA and
the DGCL, a shareholder of a corporation participant in certain major corporate
transactions may, under varying circumstances, be entitled to appraisal rights
pursuant to which such shareholder may receive cash in the amount of the "fair
value" of his or her shares, as determined by a court, in lieu of the
consideration he or she would otherwise receive in the transaction. However, the
VSCA further provides that holders of shares of a Virginia corporation which has
shares listed on a national securities exchange or which has at least 2,000
record shareholders are not entitled to dissenters' rights unless certain
requirements are met. Because MSBC has more than 2,000 record shareholders,
shareholders of MSBC generally do not have rights to dissent from mergers,
consolidations and certain other corporate transactions to which MSBC is a
party. For a description of certain provisions of the DGCL regarding appraisal
rights see "Rights of Dissenting Shareholders" and Appendix III to this Proxy
Statement/Prospectus.

                          DESCRIPTION OF THE COMPANIES

MainStreet Financial Corporation

      MSBC is a multi-bank holding company headquartered in Martinsville,
Virginia, with total assets of $2.0 billion and total shareholders' equity of
$155.3 million at March 31, 1998. Organized in 1977, MSBC through its eleven
affiliate banks (the "MainStreet Banks"), and MainStreet Trust Company, National
Association, a nationally chartered trust company (the "Trust Company"), engages

a broad spectrum of full-service banking and trust services to consumers,
businesses, institutions and governments, including accepting demand, savings
and time deposits; making commercial, personal, installment, mortgage and

      In November 1997, MSBC created a Delaware statutory business trust
subsidiary ("MainStreet Capital Trust I") which issued approximately $50 million
of trust preferred securities. MainStreet Capital Trust I, then in turn, used
the proceeds from the sale of the trust securities to acquire Junior
Subordinated Debentures of MSBC which have the same rate, payment of dividends
and maturity.

                      PROPOSAL II - ELECTION OF DIRECTORS

      The Ballston Board is composed of seven members. The bylaws of Ballston
require that the Board of Directors shall be elected annually. The nominees set
forth below are being elected for a term expiring in 1999 or, if earlier, until
the consummation of the Merger.

      It is intended that the persons named in the proxies solicited by the
Ballston Board will vote for the election of the named nominees. If any nominee
is unable to serve, the shares represented by all valid proxies will be voted
for the election of such substitute as the Ballston Board may recommend. At this
time, the Ballston Board knows of no reason why any nominee might be unavailable
to serve.

      Pursuant to Article II, Section 19 of the Ballston's Bylaws, nominations,
other than those made by or at the direction of the Ballston's Board, shall be
made pursuant to a notice in writing to the Secretary of Ballston that is
delivered to, or mailed and received at, the principal executive offices of
Ballston not later than the close of business on the tenth day following the
date on which notice of such meeting is first given to stockholders. Under the
Ballston Bylaws, a shareholder's notice must set forth certain specific
information about the person whom the shareholder proposes to nominate for
election as a director and about the shareholder giving the notice. If such a
nomination is properly made, ballots will be provided for use by shareholders at
the annual meeting bearing the name of such nominee or nominees.

      The following table sets forth information with respect to the nominees
and their name, age, principal occupation during the past five years, the year
he or she first became a director, the year in which his or her current term
will expire and the number of shares and percentage of Ballston Common Stock
beneficially owned on the Record Date. The table also sets forth, as of the
Record Date, the ownership of shares of Ballston Common Stock by each
shareholder known to Ballston to beneficially own more than 5% of the Ballston
Common Stock outstanding.

Meetings and Committees of the Ballston Board

         Ballston's Board conducts its business through meetings of the Board.
During the fiscal year ended December 31, 1997, the Ballston Board held 4
regular meetings and 5 special meetings. No director of Ballston attended fewer
than 75% of the total meetings of the Ballston Board and committee meetings on
which such Board member served during the period. The Ballston Board does not
have an audit committee, nominating committee or compensation committee.

         Ballston's full Board of Directors selects the nominees for election as
directors in accordance with the Ballston's Bylaws. While the Ballston Board
will consider nominees recommended by stockholders, it has not actively
solicited recommendations from the Ballston's shareholders for nominees nor,
subject to the procedural requirements set forth in the Ballston's Bylaws,
established any procedures for this purpose.

Board Compensation

         During 1997, members of the Ballston Board received a fee of $250 per
each Board meeting attended. For the year ended December 31, 1997, total
aggregate fees paid by Ballston to its directors were $11,000.

Executive Compensation

         The following table sets forth the cash and non-cash compensation
concerning the executive officers of Ballston or The Bank. No other executive
officer of either Ballston or The Bank had a salary or bonus during the years
ended December 31, 1997 and 1996 that exceeded $100,000 for services rendered in
all capacities to Ballston or The Bank. Mr. Burroughs resigned from The Bank on
December 31, 1997.

Profit Sharing and Savings Plan

         The Bank has adopted an Employees Profit Sharing and Savings Plan (the
"Plan") effective January 1, 1990. Employees of The Bank who have completed one
year of service and are at least twenty-one years old are eligible for
participation in the Plan. Participants may direct The Bank to contribute up to
15 percent of their pre-tax income through payroll deductions. The Bank will
provide a matching contribution of from 25 to 100 percent of the participant's
contribution, depending upon years of service. The matching scheme is applicable
only to the first 6 percent of the participant's pre-tax income. The Board of
Directors of The Bank may, at its own discretion from year to year, vote to
cause additional contributions to be made to the Plan for all employees.
Employees may also make after-tax contributions of up to 15 percent of their
after-tax income. The amounts, within certain limitations, remain non-taxable to
the employee until distribution.

         All Plan assets are held by QUADs Trust, Frederick, Maryland as Trustee
and invested in one or more of four mutual funds administered by the
Massachusetts Mutual insurance group. The participant directs the Trustee among
investment options. The Trustee has no discretion with respect to the investment
options. A participant's account is payable upon his or her retirement or upon
the earlier occurrence of certain defined disabilities, death or termination of
employment. The amount payable upon the occurrence of such events is subject to
a vesting schedule under which an employee becomes fully vested in the
contributions of The Bank after six years of service.

Certain Transactions with Ballston

         The Bank, like many financial institutions, has followed a policy of
granting various types of loans to officers, directors, and employees. The loans
have been made in the ordinary course of business and on substantially the same
terms, including interest rates and collateral, as those prevailing at the time
for comparable transactions with The Bank's other customers, and do not involve
more than the normal risk of collectibility, or present other unfavorable
features.

             PROPOSAL III - RATIFICATION OF APPOINTMENT OF AUDITORS

         Stoy, Malone & Company, P.C. was Ballston's independent auditors for
the 1997 fiscal year. The Board presently intends to renew Ballston's
arrangement with Stoy, Malone & Company, P.C. to be its independent auditors for
the fiscal year ending December 31, 1998, or, if earlier, until consummation of
the Merger, subject to ratification by Ballston shareholders. A representative
of Stoy, Malone & Company, P.C. is not expected to be present at the Annual
Meeting. The Board of Directors recommends that shareholders vote "FOR" the
ratification of the appointment of auditors.

         The consolidated financial statements of MSBC as of December 31, 1997
and 1996, and for each of the years in the three year period ended December 31,

independent auditors, as stated in their report appearing herein, and have been
so included in reliance upon the report of such firm given upon their authority
as experts in accounting and auditing.

                                 LEGAL MATTERS

         The validity of MSBC common stock to be issued to Ballston Shareholders
pursuant to the Merger and certain other legal matters in connection with the
Merger will be passed upon for MSBC by Flippin, Densmore, Morse, Rutherford &
Jessee, A Professional Corporation, Roanoke, Virginia.


                                 OTHER MATTERS

         As of the date of this Proxy Statement, management of Ballston know of
no other business that will come before the Annual Meeting. Should any other
matters properly come before the Annual Meeting, the proxy in the enclosed form
confers upon the person or persons designated to vote the shares discretionary

         (A)  Outstanding  MSBC Common  Stock.  The shares of MSBC Common  Stock
issued and outstanding  immediately prior to the Merger Effective Date shall, on
and after the Merger  Effective Date,  remain issued and  outstanding  shares of
MSBC Common Stock.

         (B) Outstanding  Ballston Common Stock.  Each share  (excluding  shares
held by  Ballston,  BNV or by MSBC or by any of the MSBC  Subsidiaries,  in each
case other than in a  fiduciary  or  custodial  capacity or as a result of debts
previously  contracted (the "Excluded  Shares")) of Ballston 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  that  number of shares of MSBC  Common  Stock  (the  "Exchange  Ratio")
obtained  (subject to the next  following  sentence)  by dividing  $12.04 by the
average of the bid price and the asked price per share for MSBC Common  Stock as
reported on the Nasdaq  National Market for each of the twenty (20) trading days
preceding the tenth  calendar day prior to the Merger  Effective  Date ("Average
MSBC Share Price") (which, together with cash required to be paid for fractional
shares under Section II(D) is referred to as the "Merger Consideration"). If the
ratio computed in accordance  with the  immediately  preceding  sentence is less
than 0.4025,  the Exchange  Ratio shall be 0.4025,  and if the ratio computed in
accordance with the immediately  preceding  sentence is greater than 0.4920, the
Exchange Ratio shall be 0.4920.

         (C) Stockholder Rights; Stock Transfers.  On the Merger Effective Date,
holders of Ballston Common Stock shall cease to be, and shall have no rights as,
stockholders   of   Ballston   other  than  the  right  to  receive  the  Merger
Consideration.  After the Merger  Effective Date, there shall be no transfers on
the stock transfer books of Ballston or the Continuing Corporation of the shares
of Ballston 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 MSBC Common Stock and no certificates or scrip therefor, or
other evidence of ownership thereof, will be issued in the Merger; instead, MSBC
shall pay to each  holder of  Ballston  Common  Stock  who  would  otherwise  be
entitled to a fractional  share an amount in cash determined by multiplying such
fractional share by the Average MSBC Share Price.

         (E) Exchange  Procedures.  As promptly as practicable  after the Merger
Effective Date,  MSBC shall send or cause to be sent to each former  stockholder
of Ballston of record immediately prior to the Merger Effective Date transmittal
materials for use in exchanging such stockholder's  certificates of Ballston for
the  Merger  Consideration.   Any  fractional  share  checks  which  a  Ballston
stockholder  shall be  entitled to receive in  exchange  for such  stockholder's
shares of Ballston  Common Stock,  and any dividends  paid on any shares of MSBC
Common Stock,  that such  stockholder  shall be entitled to receive prior to the
delivery to MSBC of such  stockholder's  certificates  representing  all of such
stockholder's  shares  of  Ballston  Common  Stock  will  be  delivered  to such
stockholder  only upon delivery to MSBC (or to whomever MSBC shall  designate in
the transmittal  materials) of the certificates  representing all of such shares
(or indemnity satisfactory to MSBC, in its judgment, 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 Ballston shall be entitled to
vote at any meeting of holders of MSBC Common Stock,  the number of whole shares
of MSBC Common Stock into which their respective shares of Ballston Common Stock
are  converted,   regardless  of  whether  such  holders  have  exchanged  their
certificates  representing  Ballston Common Stock for certificates  representing
MSBC Common Stock in accordance with the provisions of this Plan.

         (F) Shares Held by  Ballston  or MSBC.  All  Excluded  Shares  shall be
canceled and retired at the Merger Effective Date and no consideration  shall be
issued in exchange therefor.

         (G) Anti-Dilution  Provisions.  In the event MSBC changes the number of
shares of MSBC Common Stock issued and outstanding prior to the Merger Effective
Date as a result of a stock split, stock dividend,  recapitalization  or similar
transaction with respect to the outstanding MSBC Common Stock (but not including
shares issued in connection with a merger, share exchange or similar transaction
whose  primary  purpose is the  acquisition  for value of a going  concern or in
connection  with a  dividend  reinvestment  plan or a grant  of  stock  or stock
options  to one or more  employees  or  directors  or the  exercise  of any such
options)  and the record date  therefor  shall be prior to the Merger  Effective
Date, the Exchange Ratio shall be proportionately  adjusted by multiplying it by
a fraction  the  numerator of which is the number of shares of MSBC Common Stock
outstanding  immediately  after such transaction and the denominator of which is
the number of shares of MSBC Common Stock  outstanding  immediately  before such
transaction.

         (H) Dividends.  Ballston shareholders shall not under any circumstances
be entitled to any dividend  (cash or otherwise)  declared by MSBC with a record
date prior to the Merger Effective Date.

"Ballston  Reports").  Ballston represents and warrants to MSBC: (a) that, as of
their  respective  dates,  the Ballston Reports referred to in (1) and (2) above
are  accurate  and complete  and fairly  present the  financial  position of the
entity or entities to which they relate and each of the statements of income and

401(a) of the Internal Revenue Code of 1986, as amended (the "Code"),  except as
Previously  Disclosed  has  received a favorable  determination  letter from the

any entity which is considered  one "employer"  with it or any Subsidiary  under

Plan, and there has been no material adverse change in the financial position of

         (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) Agreements  with Bank  Regulators.  Except as Previously  Disclosed
neither it nor any Subsidiary is a party to any written  agreement or memorandum
of  understanding  with,  or  a  party  to  any  commitment  letter  or  similar
undertaking  to, or is subject to any order or  directive  by, or a recipient of
any  extraordinary  supervisory  letter from, any bank regulator which restricts
the conduct of its business,  or in any manner relates to its capital  adequacy,
its credit or reserve policies or its management, nor has it been advised by any
bank  regulator that it is  contemplating  issuing or requesting any such order,
decree,  agreement,  memorandum  of  understanding,   extraordinary  supervisory
letter, commitment letter or similar submission.

         (O) Subsidiaries.  In the case of Ballston only, it has no subsidiaries
other than BNV, all of the outstanding shares of which are validly issued, fully
paid and  nonassessable  (except  pursuant to 12 USC ss. 55 or comparable  state
law,  if  any)  and are  owned  by it  free  and  clear  of all  liens,  claims,
encumbrances and restrictions on transfer whatsoever.  In the case of MSBC only,
its only Subsidiaries are the MSBC  Subsidiaries,  all of the outstanding shares
of which are validly issued, fully paid and nonassessable (except pursuant to 12
USC ss. 55 or  comparable  state  law) and are owned by it free and clear of all
liens, claims, encumbrances and restrictions on transfer whatsoever.

         (P) Collective Bargaining Contracts. Neither it nor any Subsidiary 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 or is the
subject of a proceeding  asserting  that it or the  Subsidiary  has committed an
unfair labor practice  (within the meaning of the National Labor  Relations Act)
or seeking to compel it or the Subsidiary to bargain with any labor organization
as to wages and conditions of employment. There is not any strike or other labor
dispute  involving it or any Subsidiary and to the best of its knowledge none is
threatened. It is not aware of any activity involving the employees of it or any
Subsidiary  seeking to certify a collective  bargaining  unit or engaging in any
other organization activity.

         (Q)  Classified  Assets and Loan and Lease Loss  Reserve.  Ballston has
Previously  Disclosed a list of the loans,  extensions of credit or other assets
of BNV that were  classified  by the  examiners  of the  Federal  Reserve  Board
("FRB")  or by the  Bureau  of  Financial  Institutions  of the  Virginia  State
Corporation  Commission  ("Virginia  Bank  Regulator")  in its  last  respective
preceding examination ("BNV Asset  Classification") and has Previously Disclosed
a list of its loans and  extensions of credit by BNV in the  respective  initial
principal  amount of $10,000 or more, any payment of which is, as of the date so
disclosed, delinquent ("BNV Delinquent Loan List"). The BNV Asset Classification
and the BNV Delinquent Loan List are, respectively, accurate and complete in all
material  respects  and no  loans,  extensions  of credit  or other  assets  (or
portions thereof) that have been classified as of the respective date of the BNV
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 BNV Asset  Classification  other than
amounts of loans,  extensions of credit or other assets that were charged off by
BNV prior to the respective date of the BNV Asset Classification. BNV's loan and
lease loss reserve as Previously  Disclosed to MSBC are  reasonably  believed by
Ballston  and  BNV  to be  adequate  as of the  date  thereof  and no  event(s),
occurrence(s),  condition(s) or circumstance(s)  has or have occurred which have
had, will have, or are reasonably  likely  (individually or in the aggregate) to
have the effect of  rendering  such loan and lease loss  reserve  inadequate  or
causing a material addition to the reserve to be made.



                                       11

         (R)  Affiliates.  In the case of Ballston  only,  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 it as that term is used in

Stock Option Agreement from, or the  transactions  contemplated by this Plan and
the Stock Option  Agreement  are otherwise  exempt from,  any  applicable  state
takeover  laws in effect as of the date of this Plan,  including  section 203 of
the DGCL.

         (V) Approval of This Transaction.  In the case of Ballston only, it has
taken all  action so that the  entering  into of this Plan and the Stock  Option
Agreement  and the  consummation  of the  transactions  contemplated  hereby and
thereby  (including  without  limitation  the  Merger)  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 Certificate of Incorporation or Bylaws or, except
as  granted  hereunder  or under the Stock  Option  Agreement  or as  Previously

contingent  on a  merger  or  change  in  control  in any  lease  or  employment
agreement);  or (3) except as set forth in Paragraphs (B) and (C) of Article VI,

party to any agreement,  indenture or  instrument;  or (4) restrict or impair in
any way the ability of MSBC to exercise  the rights  granted  hereunder or under
the Stock Option Agreement.

its Subsidiary,  the  Participation  Facilities and the Loan Properties (each as

defined below),  except for instances of noncompliance  which are not reasonably
likely,  individually or in the aggregate,  to have a Material Adverse Effect on

defined  below),  whether  or not  occurring  at or on a site  owned,  leased or
operated by it, its Subsidiary or any  Participation  Facility,  except for such
proceedings  pending or threatened that are not reasonably likely,  individually
or in the aggregate, to have a Material Adverse Effect on it;

                  (3)  to its  knowledge,  there  is no  proceeding  pending  or
threatened  before any  court,  governmental  agency or board or other  forum in

proceedings,  reasonably  would  be  expected  to be,  named as a  defendant  or
potentially  responsible party (a) for alleged  noncompliance  (including by any
predecessor)  with any  Environmental  Law or (b)  relating  to the  release  or
threatened  release into the environment of any Hazardous  Material,  except for

laws, to permit  consummation of the Merger within the time contemplated by this
Agreement and to otherwise enable consummation of the transactions  contemplated
hereby and by the Stock  Option  Agreement  and shall  cooperate  fully with the
other parties hereto to that end (it being understood that any amendments to the
Registration  Statement (as hereinafter  defined) or a resolicitation of proxies
as a  consequence  of an  acquisition  agreement  by MSBC shall not violate this
covenant),  including  (1) using its best  efforts to lift or rescind  any order
adversely  affecting its ability to  consummate  the  transactions  contemplated

that one party  hereto  notifies the other party  pursuant to  Paragraph  (B) of
Article VII that a breach has occurred in this Plan, either party shall have the
option of suspending  its  obligations  under this Paragraph or Paragraph (O) of
this Article until such time as the breach has been cured.

proxy statement (the "Proxy  Statement") to be mailed to the holders of Ballston
Common  Stock  in  connection  with  the  Merger  and to be  filed  by MSBC in a
registration statement (the "Registration  Statement") with the SEC, which shall
conform  to  all  applicable  legal  requirements;   (2)  without  limiting  the
foregoing,  at the time such Proxy  Statement  or any  amendment  or  supplement

provisions  (to the extent  applicable) of the Exchange Act 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  contained
therein not misleading; provided, however, in no event shall any party hereto be
liable  for any  untrue  statement  of a material  fact or  omission  to state a
material fact in the Proxy  Statement  made in reliance  upon, and in conformity
with, written information concerning another party furnished by such other party
specifically for use in the Proxy Statement; (3) it shall hold a special meeting
(the  "Meeting") of the holders of Ballston  Common Stock as soon as practicable
after the  Registration  Statement  has become  effective for purposes of voting
upon this  Plan,  the Plan of Merger  and the  Merger  contemplated  hereby  and
thereby,  and (4) it shall use its best  efforts to solicit and obtain  votes of
the holders of Ballston  Common Stock in favor of the above  proposals and shall
once,  at MSBC's  request,  recess  or  adjourn  the  Meeting  for a period  not
exceeding ten days (unless Ballston  consents to a longer period) if such recess
or adjournment is deemed by MSBC to be necessary or desirable.

respects with the  provisions  of the  Securities  Act and any other  applicable
statutory  or  regulatory  requirements,  and (2) 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  contained  therein  not
misleading;  provided, however, in no event shall any party hereto be liable for
any untrue  statement of a material fact or omission to state a material fact in
the  Registration  Statement  made in reliance  upon,  and in  conformity  with,
written  information  concerning  another  party  furnished  by such other party
specifically  for use in the  Registration  Statement.  In  connection  with the
preparation  of  the   Registration   Statement  and  related   Prospectus/Proxy

rule.

         (F) Review of Information.

                  (1) Upon  reasonable  notice,  it shall afford the other party

commitments,  properties  and records to the extent  permitted by law and to its
officers,  employees,  counsel  and  accountants,  authorizing  each  of them to

furnish  promptly to the other party hereto (a) a copy of each material  report,
schedule  and other  document  filed by it pursuant to the  requirements  of the
Federal Securities Laws or any state laws, rules and regulations  regulating the
issuance,  sale or  exchange  of  securities  or the markets in which any of the
foregoing  occurs ("Blue Sky Law(s)" which together with the Federal  Securities
Laws are hereinafter  referred to as the "Securities Laws") or banking laws, and
(b) all other information  concerning its business,  properties and personnel as
the other parties hereto may reasonably request. The foregoing process is herein
referred to as "due  diligence".  No due  diligence  by any party or the results
thereof  shall  affect or be deemed  to  modify or waive any  representation  or
warranty made by any other party hereto or the  conditions to the  obligation of
the first party to consummate the transactions contemplated by the Plan.

                  (2)  Each  party  hereto  agrees  not to use  any  information
obtained in due  diligence  for any purpose  unrelated to its  evaluation of the
transactions  contemplated by this Plan and the Stock Option  Agreement.  If the
Merger is not  consummated,  each party will hold all  information and documents
obtained in due diligence in confidence (as provided in Paragraph (F) of Article
VIII) except to the extent that  disclosure  to a third party is for the purpose
of assisting in the assessment of such  information or documents for purposes of
evaluating this Plan and its  consummation (in which case reasonable steps shall
be taken to preserve  the  confidentiality  thereof) and in any event unless and
until such time as such information or documents become publicly available other
than by reason of any action or failure to act by such party or as it is advised
by  counsel  that  any  such  information  or  document  is  required  by law or
applicable  NASD or stock  exchange  rule to be  disclosed.  In the event of the
termination  of this Plan,  each party will,  upon  request by the other  party,
deliver to the other all documents so obtained by it or destroy such documents.

         (G) No  Solicitation.  In the case of Ballston only, from and including
the date of this Plan until the Merger Effective Date or the termination of this
Plan  pursuant to its terms,  (1) it shall not, and shall  direct the  officers,
directors,  employees and other persons  affiliated  with it and any  investment
banker, attorney,  accountant or other representative of it, not to, directly or
indirectly,  solicit or encourage  inquiries  or  proposals  with respect to, or
(except as required by the fiduciary duties of its Board of Directors as advised
in writing by its counsel in connection  with an  unsolicited  bona fide written
proposal)  furnish any nonpublic  information  relating to or participate in any
negotiations or discussion  concerning,  any acquisition or purchase of all or a
substantial portion of the assets of, or a substantial equity interest in, it or
any merger or other business  combination  with it other than as contemplated by
this Plan,; (2) shall notify MSBC immediately if any such inquiries or proposals
are  received  by, or any such  negotiations  or  discussions  are  sought to be
initiated with, it; (3) shall instruct its officers, directors, agents, advisors
and affiliates to refrain from doing any of the foregoing; and (4) shall furnish
to MSBC copies of all documents  reviewed or received by it in  connection  with
any inquiries, proposals, negotiations and discussions referred to in Subsection
(G)(2).

         (I) Blue Sky.  In the case of MSBC  only,  it shall use its  reasonable
best  efforts  to  obtain,  prior  to the  effective  date  of the  Registration

after the date  hereof  (and  within ten (10) days  after any person  becomes an
"affiliate"  thereafter),  to execute and deliver to MSBG a letter  agreement in
the form  attached  hereto as  Exhibit B  restricting  the  disposition  of such

and change its credit, investment,  asset-liability management, risk management,
litigation,  and real estate  valuation  policies and practices  (including loan
classifications  and levels of reserves) prior to the Merger Closing so as to be
consistent  on a mutually  satisfactory  basis with those of MSBC and  generally
accepted accounting principles.  Additionally,  Ballston hereby agrees to accrue
all investment banking, legal and accounting costs associated with this Plan and
the  transactions  contemplated  hereby  between  the date of this  Plan and the
anticipated  Effective  Date.  Except as provided in the  immediately  preceding

practices,  however,  until  (x)  satisfaction  of the  conditions  set forth in

shall  reasonably  agree that the  Merger  Closing  will  occur  prior to public
disclosure  of such  modifications  or  changes  in  regular  periodic  earnings
releases or periodic reports filed with the SEC or other applicable governmental
authority  available to the public,  and (z) such time as MSBC  acknowledges  in
writing that all  conditions to MSBC's  obligation to consummate the Merger (and
MSBC's rights to terminate  this Plan) have been waived or satisfied;  provided,
however, that in all circumstances Ballston shall and shall cause its Subsidiary
to make such  modifications  and changes not later than immediately prior to the
Merger  Effective  Date.  Ballston's  representations,  warranties and covenants
contained  in the Plan  shall not be deemed  to be  untrue  or  breached  in any
respect  for any  purpose  as a  consequence  of any  modifications  or  changes
undertaken solely on account of this Paragraph (K).

exemption of) the  transactions  contemplated  by this Plan and the Stock Option

applicable state takeover law, as now or hereafter in effect, including, without
limitation, Section 203 of the DGCL.

Plan and the Stock Option  Agreement and the  consummation  of the  transactions
contemplated hereby and thereby (including without limitation the Merger and the
exercise of the Option) and any other action or combination  of actions,  or any
other transactions  contemplated hereby or thereby do not and will not result in
the grant of any rights to any person  under the  Articles of  Incorporation  or
Bylaws of Ballston  or under any  agreement  (including  any lease,  credit,  or
employment, severance or officer, director or employee compensation agreement or
plan) to which  Ballston  is a party  (other  than as  Previously  Disclosed  by
Ballston); or (2) it shall not restrict or impair in any way the ability of MSBC
to exercise the rights granted hereunder or under the Stock Option Agreement.

its Participating  Cumulative Preferred Stock, Series A, of which 100,000 shares
are  authorized  but unissued as of December 31, 1997,  in a manner that affects
holders of Ballston Common Stock in a disproportionate manner.

within ten days after  discovering  the same)  notify the other party  hereto in
writing of any event(s),  occurrence(s),  condition(s) or circumstance(s)  which
alone or in the  aggregate  results  or is  reasonably  likely  to result in the
inaccuracy of any warranty or  representation or warranty or the material breach
of any covenant or agreement in this Plan of the party discovering the same.

consummate  the  Merger  including,  but not  limited  to,  promptly  furnishing
information  relating  to it and  its  Subsidiaries  required  to be  set  forth
therein;  provided,  however, that any approval shall not require a change which
materially adversely impacts the economic or business benefits to either MSBC or
Ballston  of  the  transactions  contemplated  by  this  Plan  so as  to  render
inadvisable  the  consummation  of the Merger in the  reasonable  opinion of the
Board of Directors of either MSBC or Ballston.

         (Q) Environmental Tests. Ballston and its Subsidiary will allow MSBC to
conduct, through designated representatives, environmental and engineering tests

         (B) On Breach. By MSBC or Ballston, in the event (1) any representation
or warranty  contained herein made by the other party is breached and the 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,  or (2) a material breach


                                       21
<PAGE>

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.

         (C) Failure to Consummate  on Time.  By MSBC or Ballston,  in the event
that the Merger is not consummated by September 30, 1998.

         (D) Failure to Obtain Certain  Approvals.  By MSBC or Ballston,  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;  or (2) if any regulatory  approval  contemplated  by
Paragraph  (B) of Article VI to the extent  necessary to  consummate  the Merger
legally, is finally and unconditionally denied.

         (E)  Failure to  Execute  Stock  Option  Agreement.  By MSBC,  upon the
failure of Ballston to execute and deliver to MSBC the Stock  Option  Agreement,
contemporaneously with the execution of this Plan.

         (F) Possible  Adjustment in Exchange  Ratio. By Ballston during the ten
(10) day period commencing on the Determination Date (as hereinafter defined) if
both of the following conditions are satisfied:

         (1) if the Average MSBC Share Price is less than $24.47; and

         (2) if the First Percentage  exceeds the Second  Percentage by at least
ten (10) percentage points; subject,  however, to the immediately following four
sentences.  If Ballston  elects to exercise its  termination  right  pursuant to
Paragraph  (F) of Article  VII,  it shall  give  prompt  written  notice to MSBC
(provided that such notice of election to terminate may be withdrawn at any time
within the aforementioned ten (10) day period).  During the seven (7) day period
commencing  with its  receipt  of such  notice,  MSBC  shall  have the option of
increasing the  consideration  to be received by the holders of Ballston  Common
Stock by adjusting  the Exchange  Ratio,  to equal a quotient,  the numerator of
which is  $24.47  multiplied  by the  Exchange  Ratio (as then in  effect)  with
respect to Ballston  Common Stock,  and the  denominator of which is the Average
MSBC Share Price.  If MSBC makes the election  contemplated  by the  immediately
preceding  sentence,  it shall give  prompt  written  notice to Ballston of such
election, whereupon no termination shall have accrued pursuant to this Paragraph
(F) and the Plan shall remain in effect in accordance  with its terms (except as
the Exchange  Ratio shall have been so modified) and any references in this Plan
to "Exchange Ratio" shall thereafter be deemed to refer to the Exchange Ratio as
adjusted pursuant to this Paragraph (F).

         For purposes of this  Paragraph (F) the following  terms shall have the
meanings indicated:

         "Determination  Date" means the tenth  calendar day prior to the Merger
Effective Date.

         "First Percentage" means the percentage  resulting from: (a) taking the
remainder  ("First  Remainder")  obtained by subtracting  the Average MSBC Share
Price from  $27.19;  and (b)  dividing  the First  Remainder by the Average MSBC
Share Price.

         "Second Percentage" means the percentage resulting from: (a) taking the
remainder  ("Second  Remainder")  obtained by subtracting the SNL Southeast Bank
Index  reported  most  recently  prior to the last trading day in the  measuring
period for  calculating  the Average MSBC Share Price  ("Recent SNL Bank Index")
from the SNL Southeast Bank Index reported most recently prior to or on February
13, 1998; and (b) dividing the Second Remainder by the Recent SNL Bank Index.



                                       22
<PAGE>

         (G) Fiduciary Duty. By Ballston,  if its board of directors (on written
advice of counsel  that such  recommendation  is  necessary to comply with their
fiduciary  duty) shall have  determined to recommend an acquisition  proposal to
its stockholders after determining that such acquisition proposal is superior in
value to the  stockholders  to the  transaction  contemplated  by the Plan,  and
Ballston  gives MSBC at least three business days' prior notice of its intention
to effect such termination pursuant to this Paragraph.

                              VIII. OTHER MATTERS.

(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) of Article V and Paragraphs (A), (D), (E), (F) and
(I) of this Article VIII shall  survive  such  termination.  In the event of the

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) of this Article.

         (B)  Waiver,  Amendment.  Prior  to  the  Merger  Effective  Date,  any
provision  of  this  Plan  may  be (1)  waived  by the  party  benefited  by the

the  transaction),  by an agreement in writing among the parties hereto approved
by or approved in the manner  authorized by their respective Boards of Directors
and executed in the same manner as this Plan, except that, after the vote by the
stockholders of Ballston,  the  consideration to be received by the stockholders
of Ballston  for each share of  Ballston  Common  Stock  shall not be  decreased
except as expressly provided herein.

         (C)   Counterparts.   This  Plan  may  be   executed  in  one  or  more

hereto.

         (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.  In the event  that the Plan is  terminated  in
accordance with the provisions of Article VII otherwise than pursuant to Section
VII(B) on  account  of a breach by one party (so long as the other  party is not
also in  breach),  each party  shall bear its own  costs,  expenses  and fees 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).  In the event that the Plan is terminated pursuant to
Article VII(B), the total documented  out-of-pocket  costs,  expenses,  and fees

of whether incurred before or after the execution of this Plan), so long as such
other party shall not also be in breach,  in connection  with and arising out of
the Merger and other transactions contemplated by this Plan shall be paid by the
breaching party and the breaching  party shall promptly make such  reimbursement
to the non-breaching party as is necessary to effectuate the same.

         (F)  Confidentiality.  Except as otherwise provided in Paragraph (F)(2)

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
MSBC and the  indemnified  party.  MSBC shall use its reasonable best efforts to
provide  coverage to the officers and  directors of MSBC and BNV,  respectively,
under MSBC 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 MSBC and the  Continuing  Corporation  shall  reimburse MSBC for the
additional  premium  incurred by it in connection  with providing such coverage;
(2) If MSBC 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 MSBC shall assume the  obligations  set forth
in this  Paragraph  (K)(1).  MSBC  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).  MSBC
shall have no obligation to maintain directors and officers liability  insurance
under this Section if MSBC  determines in good faith that (a) such  insurance is
not  reasonably  available;  or (b) the  premium  costs  for such  insurance  is
disproportionate to the amount of coverage provided, (c) the incremental premium
costs for such  coverage  exceed 175% of the amount per annum  Ballston  and BNV
paid in its  last  full  fiscal  year,  or (d)  the  coverage  provided  by such
insurance is limited by exclusives so as to provide an insufficient  benefit (it
being  understood that if such exclusives are not materially  greater than those
in effect for MSBC as of December 31, 1997, this clause (d) cannot be invoked).

         (L)  Acquisition of MSBC. In the event that MSBC is acquired  through a
merger,  share  exchange or other  business  combination  in which it is not the
surviving entity, MSBC agrees that it shall make provision by which the acquirer
shall assume this  Agreement and the holders of Ballston  Common Shares shall be
entitled  to receive  the same  consideration  for such shares as the holders of
MainStreet Common Stock received, giving effect to the Exchange.

         (M)  Alternative  Structure.  Notwithstanding  anything to the contrary
contained in this Plan,  subject to the final sentence of this Section (M), MSBC
may,  at its  sole  option,  elect to  either  (a)  form a  separate  subsidiary
corporation  and merge it into Ballston or Ballston into it such that MSBC shall
be the sole shareholder of the surviving  corporation,  or (b) convert this Plan
to an exchange  of Ballston  Common  Stock for MSBC Common  Stock,  instead of a
merger,  on the same terms and  conditions  contained  herein  (except  for such
conversion);  provided,  however,  that MSBC may not make such an election if it
would result in failure to satisfy the condition set forth in either Section (M)
or (P) of Article VI. In the event MSBC makes an election  pursuant to the prior
sentence,   Ballston  shall  take  all  actions  reasonably  requested  by  MSBC
(including  without  limitation  using its best efforts to obtain any  requisite
corporate and stockholder approvals in connection therewith).  In the event that
MSBC makes an election  pursuant to the first  sentence of this Section (M), the
parties  hereto agree  promptly to amend this Plan as MSBC may  reasonably  deem
necessary or appropriate.  If MSBC reasonably  determines that the Merger cannot
be effected  pursuant to this Plan (other than pursuant to this Section (M)) and
MSBC also reasonably determines that the transactions  contemplated by this Plan
can be effected if one or more of the actions  contemplated  by this Section (M)
are taken, then MSBC shall elect to take one or more of the actions contemplated
by this Section (M); provided,  however, that MSBC shall not be required to take
any such action if the taking of such action is, in MSBC's reasonable  judgment,
reasonably likely to result in the failure of any of the conditions set forth in
Article VI.

                                  APPENDIX II

                                 March 11, 1998

Board of Directors
Ballston Bancorp Inc.
1110 N. Glebe Road, Suite 1080
Arlington, Virginia  22201

Dear Board Members:

         Set forth herein is the opinion of Danielson Associates Inc.
("Danielson Associates") as to the "fairness" of the offer by MainStreet
BankGroup, Inc. ("MainStreet"), a bank holding company domiciled in
Martinsville, Virginia to acquire all of the shares of the common stock of
Ballston Bancorp, Inc. ("Balls ton" or the "Bank") of Arlington, Virginia. The
"fair" value is defined as the price at which all of the shares of Ballston's
common stock would change hands between a willing seller and a willing buyer
with each having had a reasonable knowledge of the relevant facts. In opining as
to the "fairness" of the offer, it also must be determined if the MainStreet
common stock to be exchanged for Ballston's common stock is "fairly" valued.

         In preparing this opinion, the Bank's market has been analyzed; its
business and prospects have been reviewed; and its performance has been compared
with banks in similar markets. In addition, any unique characteristics have been
considered.

         This opinion is based partly on data supplied to Danielson Associates
by Ballston, and it relies on some public information, all of which is believed
to be reliable, but neither the completeness nor accuracy of such information
can be guaranteed. In particular, the opinion assumes that there are no
significant asset quality problems beyond what is stated in recent reports to
regulatory agencies.

         In determining the "fair" sale value of Ballston, the emphasis has been
placed on prices paid for banks with similar financial, structural and market
characteristics. These prices were related to Ballston's net income, which is
the most important factor in determining its "fair" sale value.

         The "fair" market value of the MainStreet common stock to be exchanged
for Ballston stock has been determined by a comparison with other similar bank
and bank holding company stocks and included no in- person due diligence of
MainStreet. This comparison showed the MainStreet stock to be "fairly" valued.

         Based on this analysis, the "fair" sale value of Ballston is $15.7 to
$16.7 million, or $9.20 to $10.19 per share. Thus, MainStreet's offer of $19.5
million, or $12.04 per share, is a "fair" offer from a financial point of view
for Ballston and its shareholders.

                                                  Respectfully submitted,

                                                  /s/ Arnold G. Danielson

                                                  Arnold G. Danielson
                                                  Chairman
                                                  Danielson Associates Inc.

                                  APPENDIX III

              SECTION 262 OF THE DELAWARE GENERAL CORPORATION LAW

Section 262.  Appraisal rights

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

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

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

                  (2) Notwithstanding paragraph (1) of this subsection,
         appraisal rights under this section shall be available for the shares
         of any class or series of stock of a constituent corporation if the
         holders thereof are required by the terms of an agreement of merger or
         consolidation pursuant to ss.ss. 251, 252, 254, 257, 258, 263 and 264
         of this title to accept for such stock anything except:

                           a.       Shares of stock of the corporation surviving
                  or resulting from such merger or consolidation, or depository
                  receipts in respect thereof;


                                     - 1 -

<PAGE>



                           b. Shares of stock of any other corporation, or
                  depository receipts in respect thereof, which shares of stock
                  or depository receipts at the effective date of the merger or
                  consolidation will be either listed on a national securities
                  exchange or designated as a national market system security on
                  an interdealer quotation system by the National Association of
                  Securities Dealers, Inc. or held of record by more than 2,000
                  holders;

                           c. Cash in lieu of fractional shares or fractional
                  depository receipts described in the foregoing subparagraphs
                  a. and b. of this paragraph; or

                           d.       Any combination of the shares of stock,
                  depository receipts and cash in lieu of fractional shares or
                  fractional depository receipts described in the foregoing
                  subparagraphs a., b. and c. of this paragraph.

                  (3) In the event all of the stock of a subsidiary Delaware
         corporation party to a merger effected under ss. 253 of this title is
         not owned by the parent corporation immediately prior to the merger,
         appraisal rights shall be available for the shares of the subsidiary
         Delaware corporation.

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

         (d) Appraisal rights shall be perfected as follows:

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



                                              - 2 -

<PAGE>




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



                                     - 3 -

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

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

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

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


                                     - 4 -

<PAGE>



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

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

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

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

                                    GENERAL

Ballston does not engage in any  substantial  business  activity other than as a
bank holding  company that owns all of the issued and  outstanding  stock of The
Bank, its principal asset.  Unless  otherwise  noted,  the following  discussion
relates to Ballston and The Bank on a consolidated basis,  collectively referred
to as Ballston.  Ballston engages in community  banking  activities by accepting
deposits  and  investing  such  funds  primarily  in a variety  of loans.  These
community banking activities  primarily include providing commercial loans, real
estate mortgage loans, real estate  construction  loans and, to a lesser extent,
consumer  loans.  Ballston also  maintains an investment  securities  portfolio.
Ballston's lending and investing activities are funded primarily by deposits.

The  largest  component  of  Ballston's  net  income  is  net  interest  income.
Consequently,  Ballston's  earnings are primarily  dependent on its net interest
income,  which is  determined  by (i) the  difference  between rates of interest
earned on interest-earning assets and rates paid on interest-bearing liabilities
(interest rate spread), and (ii) the relative amounts of interest-earning assets
and interest-bearing liabilities.  Ballston's net income is also affected by its
provision for loan losses, other income, other expenses, and income taxes.

                                    OVERVIEW

On June 23, 1997, Ballston signed a definitive  agreement to merge with and into
a subsidiary of Abigail Adams National Bancorp,  Inc.  ("AANB").  Because of the
pendency of that merger,  Ballston's strategy to expand its operations,  through
the active pursuit of investments in securities, loan originations,  and deposit
growth,  was not  pursued as actively  as in prior  periods.  The merger was not
approved at the Special Meeting of Shareholders of AANB on December 31, 1997 and
as a result, the definitive  agreement between Ballston and AANB was terminated.
The 1997 pre-tax  earnings  were reduced by $263,000 as a result of the expenses
related to that merger.

On March 11, 1998, Ballston signed a definitive agreement to merge with and into
MSBC. It is anticipated  that the transaction will close no later than the third
quarter of 1998 and such  transaction  is  expected to be  accounted  for by the
pooling-of-interests method of accounting.

In April 1998, a new branch office (the "new branch") was opened in Falls
Church, Virginia. Ballston believes, although there is no assurance, that the
new branch

                                       1

will  result in the growth of its loan  portfolio  and  deposit  base.  Ballston
expects its other expenses may increase in 1998 due to the costs associated with
the opening of the new branch.

             COMPARISON OF DECEMBER 31, 1997 WITH DECEMBER 31, 1996

FINANCIAL CONDITION

Total assets  increased  $1,756,000 or 2.2%, to $80,336,000 at December 31, 1997
from  $78,580,000 at December 31, 1996. The increase was primarily  attributable
to a  $13,182,000  or 224.5%  increase in cash and cash  equivalents,  which was
partially  offset by decreases in investment  securities of $7,689,000 or 32.3%,
interest  bearing  deposits with financial  institutions of $1,775,000 or 41.6%,
loans of  $1,446,000  or  3.4%,  and  foreclosed  real  estate  held for sale of
$514,000 or 45.7%. Total liabilities increased $1,094,000 or 1.5% to $72,073,000
at December 31, 1997 from  $70,979,000  at December 31, 1996.  This increase was
primarily  due to increases in deposits of $1,621,000  or 2.6%,  and  securities
sold under  repurchase  agreements  of  $279,000 or 5.0%,  which were  partially
offset by a decrease  in  advances  from  Federal  Home Loan Bank of $850,000 or
55.5%.

Nonperforming  Assets.  The  following  table sets forth  information  regarding
nonperforming  assets  as  of  the  dates  indicated.   Ballston  had  no  loans
categorized as troubled debt restructurings.

Foreclosed  Real  Estate Held for Sale.  Real  estate  acquired by Ballston as a
result of  foreclosure  is classified  as  foreclosed  real estate held for sale
("Foreclosed  Real Estate")  until such time it is sold.  When  Foreclosed  Real
Estate is acquired,  it is recorded at the lower of its fair value or the unpaid
principal balance of the related loan.

Allowance for Losses on Loans and  Foreclosed  Real Estate.  It is the policy of
management  to provide  for losses on  unidentified  loans in its  portfolio  in
addition  to  classified  loans.  A  provision  for loan  losses is  charged  to
operations based on management's  evaluation of the potential losses that may be
incurred in Ballston's loan portfolio.  Management  also  periodically  performs
valuations of Foreclosed Real Estate and establishes an allowance to reduce book
values of the properties to their net realizable  values when  necessary.  As of
December 31, 1997 and 1996, there was no allowance for losses on Foreclosed Real
Estate.  The following table sets forth  information  with respect to Ballston's
allowance for loan losses for the years indicated.

RESULTS OF OPERATIONS

Net income for 1997 was $771,000 or $.48 per share in  comparison to $741,000 or
$.46 per share for 1996.  As discussed in the Overview  section,  net income for
1997 was  negatively  impacted as a result of $263,000 of pre-tax merger related
expenses  in regard  to the AANB  proposed  merger  transaction.  Without  these
special merger related expenses,  net income after taxes would have approximated
$944,000.

Net Interest  Income.  Ballston's net interest  income was  relatively  flat for
1997.  Net interest  income  increased  $129,000 or 4.0%, to $3,384,000 for 1997
from  $3,255,000 for 1996. The increase was primarily the result of a $2,448,000
or 16.2%  increase  in the  relative  amount  of  interest-earning  assets  over
interest-bearing  liabilities  during 1997 versus 1996, which more than offset a
22 basis  point net  decrease to 3.75% in the yield on  interest-earning  assets
over the rate paid on interest-bearing liabilities.

Provision for Loan Losses.  The provision  for loan losses  increased  $5,900 or
49.2%, to $17,900 for 1997 from $12,000 for 1996.  Management regularly performs
an analysis to identify the inherent  risk of loss in its loan  portfolio.  This
analysis  includes  evaluation  of the  collectibility  of the  loan  portfolio,
including  the  nature  of  the  portfolio,  credit  concentrations,  trends  in
historical loss experience,  specific  impaired loans, and economic  conditions.
Management  will  continue to monitor its  allowance  for loan losses and future
adjustments  to the allowance  through the provision for loan losses as economic
conditions  dictate.  Although the  allowance for loan losses is maintained at a
level that  management  considers to be adequate to provide for the risk of loss
in Ballston's loan portfolio,  there can be no assurance that future losses will
not exceed estimated amounts or that additional  provisions for loan losses will
not be required in future periods.

Other Income.  Other income  increased  $234,000 or 64.0% for 1997 from $365,000
for 1996.  The  majority of the increase  was the result of the  recognition  of
$191,000 in gain on sale of foreclosed  real estate.  In addition,  other income
exclusive of service charges on deposit  accounts and gain on sale of foreclosed
real estate  increased  $71,000 or 42.9%, to $236,000 for 1997 from $165,000 for
1996.  This increase was primarily a result of Ballston  instituting a policy to
charge non-bank  customers,  on a per transaction  basis, a fee for their use of
Ballston's ATM machines.  Service charges on deposit accounts  decreased $28,000
or 14.0% to  $172,000  for 1997  from  $200,000  for  1996.  Such  decrease  was
primarily the result of a decrease in  non-sufficient  fund fees.  This decrease
was not the result of Ballston's  change in  collection  policy on such fees but
rather the result of fewer customer accounts requiring such charges.

Other Expenses.  Other expenses  increased  $302,000 or 12.2%, to $2,776,000 for
1997 from $2,475,000 for 1996. The increase was primarily  attributable to other
operating  expenses  increasing  $300,000 or 34.9% to  $1,161,000  for 1997 from
$861,000 for 1996. This increase was primarily due to $263,000 of merger related
expenses in connection  with the AANB  proposed  merger  transaction.  Occupancy
expense increased $42,000 or 19.7%, to $254,000 for 1997 from $212,000 for 1996.
As discussed in the Overview  Section,  Ballston  opened a new branch  office in
Falls Church,  Virginia in April 1998. Beginning in May 1997, Ballston commenced
paying rent of  approximately  $4,200 a month on this new site,  which accounted
for most of the increase.  Salaries and employee  benefits  decreased $47,000 or
3.9%,  to  $1,169,000  for 1997 from  $1,216,000  for  1996.  The  decrease  was
primarily  the  result of the  departure  of two  executive  officers  and three
employees in the second and third quarters of 1997.

               COMPARISON OF MARCH 31, 1998 WITH DECEMBER 31, 1997

FINANCIAL CONDITION

Total assets decreased $4,661,000 or 5.8%, to $75,675,000 at March 31, 1998 from
$80,336,000  at December 31, 1997.  The decrease was primarily  attributable  to
decreases of  $7,734,000 or 40.6% in cash and cash  equivalents  and $804,000 or
2.0% in loans,  which were  partially  offset by increases  in interest  bearing
deposits  with  financial  institutions  of  $389,000  or 15.6%  and  investment
securities of $3,512,000 or 21.8%.  Total  liabilities  decreased  $4,713,000 or
6.5% to  $67,360,000  at March 31, 1998 from  $72,073,000  at December 31, 1997.
This  decrease  was  primarily  due to a decrease in deposits of  $6,604,000  or
10.2%,  which was  partially  offset by an  increase  in  securities  sold under
repurchase agreements of $1,773,000 or 30.1%.

Nonperforming  Assets. As of March 31, 1998, loans accounted for on a nonaccrual
basis totaled  $207,000 versus $211,000 as of December 31, 1997. As of March 31,
1998,  accruing  loans that are  contractually  past due 90 days or more totaled
$95,000  versus  $198,000  as of  December  31,  1997.  Ballston  had  no  loans
categorized as troubled debt restructurings as of March 31, 1998.

               COMPARISON OF THE THREE MONTHS ENDED MARCH 31, 1998
                   WITH THE THREE MONTHS ENDED MARCH 31, 1997

RESULTS OF OPERATIONS

Net income for the three  months  ended March 31, 1998 was  $105,000 or $.06 per
share in  comparison  to $164,000 or $.10 per share for the three  months  ended
March 31,  1997.  Net  income  for the three  months  ended  March 31,  1998 was
negatively  impacted as a result of $163,000 of pre-tax merger related expenses.
Without these special merger related expenses, net income after taxes would have
approximated $251,000.

Net Interest Income.  Ballston's net interest income was relatively flat for the
three  months  ended March 31, 1998 as compared to the three  months ended March
31, 1997.  Net interest  income  increased  $20,000 or 2.3%, to $847,000 for the
three months ended March 31, 1998 from $827,000 for the three months ended March
31,  1997.  The  increase  was  primarily  the result of a  $2,463,000  or 17.0%
increase in the relative amount of interest-earning assets over interest-bearing
liabilities during the three months ended March 31, 1998 versus the three months
ended March 31,  1997,  which more than offset a 26 basis point net  decrease to
3.69%  in  the  yield  on   interest-earning   assets  over  the  rate  paid  on
interest-bearing liabilities.

Provision for Loan Losses.  The provision for loan losses remained  constant for
the three months  ended March 31,  1998,  as compared to the same period for the
prior year. The allowance for loan losses totaled $617,000 at March 31, 1998.

Other Income. Other income decreased $22,000 or 19.1% for the three months ended
March 31, 1998 from $117,000 for the three months ended March 31, 1997.

Other Expenses.  Other expenses  increased  $28,000 or 4.2% for the three months
ended March 31, 1998 from  $675,000  for the three  months ended March 31, 1997.
The increase was primarily  attributable  to merger expenses of $163,000 for the
three months ended March 31, 1998,  which was partially  offset by a decrease in
salaries and  employee  benefits of $123,000 or 37.2% for the three months ended
March 31, 1998 from  $330,000 for the three  months  ended March 31,  1997.  The
decrease in salaries  and  employee  benefits  was  primarily  the result of the
departure of two executive  officers and three employees in the second and third
quarters of fiscal 1997.

                                 YEAR 2000 ISSUE

A great deal of  information  has been  disseminated  about the global  computer
crash  that may occur in the year 2000.  Many  computer  programs  that can only
distinguish  the final  two  digits of the year  entered  (a common  programming
practice)  are  expected to read  entries for the year 2000 as the year 1900 and
compute  payment,  interest  or  delinquency  based on the  wrong  date,  or are
expected to be unable to compute  payment,  interest or  delinquency.  Rapid and
accurate  data  processing  is essential  to the  operations  of Ballston.  Data
processing is also essential to most other financial institutions and many other
companies.  All of the  significant  data  processing  of Ballston that could be
affected  by this  problem is  provided by a third  party  service  bureau.  The
service  bureau has advised  Ballston that it expects to resolve this  potential
problem  before  the year  2000.  However,  if the  service  bureau is unable to
resolve  this  potential  problem  in time,  Ballston  would  likely  experience
significant data processing delays, mistakes or failures. These delays, mistakes
or failures could have a significant  adverse impact on the financial  condition
and results of operations of Ballston. It is currently anticipated that costs to
Ballston associated with the year 2000 issue will not be significant.

                         LIQUIDITY AND CAPITAL RESOURCES

The  primary   sources  of  funds  are   deposits,   repayments   of  loans  and
mortgage-backed   securities,    maturities   of   investment   securities   and
interest-bearing   deposits  with  financial  institutions,   cash  provided  by
operations  and advances  from FHLB.  While  scheduled  repayments  of loans and
mortgage-backed   securities,   and  maturities  of  investment  securities  and
interest-bearing deposits with financial institutions are predictable sources of
funds,  deposit flows and loan prepayments are greatly influenced by the general
level of interest rates, economic conditions and competition.  Ballston uses its
cash  flows to fund  existing  and future  loan  commitments,  to fund  maturing
certificates  of deposit  and  demand  deposit  withdrawals,  to invest in other
interest-earning assets, to maintain liquidity and to meet operating expenses.

At  March  31,  1998  and  December  31,  1997,  Ballston  had  $10,936,000  and
$10,452,000,   respectively,   in  approved  loan  commitments,   for  which  it
anticipates  that it will have the funds  necessary  to meet  these  obligations
through the sources of funds  mentioned  above.  The amount of time  deposits at
March 31, 1998 which is  scheduled  to mature  during the twelve  months  ending
March 31, 1999 is $20,705,000.  The amount of time deposits at December 31, 1997
which is scheduled to mature in 1998 is $21,310,000. Management believes that by
evaluating competitive instruments and pricing in its market area, it can manage
and control maturing  deposits so that a substantial  amount of such deposits is
retained in Ballston.

During the three months ended March 31, 1998 , Ballston  experienced  a net cash
outflow from financing activities of $4,872,000, primarily due to a net decrease
in deposits  of  $6,604,000,  which was  partially  offset by a net  increase in
securities sold under repurchase agreements of $1,773,000.  Ballston's investing
activities  during the three months ended March 31, 1998  resulted in a net cash
outflow of $3,161,000, primarily due to the purchase of investment securities of
$6,908,000,  which was  partially  offset by  proceeds  from the  maturities  of
investment  securities of $2,846,000  and the net decrease in loans of $789,000.
In addition,  Ballston experienced positive cash flows from operating activities
during the three months ended March 31, 1998 of $298,000.

Net cash  provided by  operating  activities  increased  $203,000  for 1997 from
$612,000 for 1996. The increase was attributable to changes in various operating
assets and  liabilities  in the normal course of business.  Net cash provided by
investing  activities for 1997 totaled  $11,447,000,  an increase of $23,387,000
from 1996 when  $11,940,000 was used in investing  activities.  The increase was
primarily attributable to a decrease in interest bearing deposits with financial
institutions  of $1,775,000 for 1997 as compared to an increase in such deposits
of  $2,386,000  for 1996, a decrease in purchases of  investment  securities  of
$11,403,000, an increase in proceeds from maturities of investment securities of
$3,000,000,  and a decrease  in loans of  $1,488,000  for 1997 as compared to an
increase  in loans of  $3,275,000  for  1996.  Net cash  provided  by  financing
activities for 1997 totaled  $920,000 as compared to  $10,050,000  for 1996. The
decrease of $9,130,000 was primarily the result of smaller increases for 1997 as
compared to 1996 of  $6,703,000 in deposits and  $1,772,000  in securities  sold
under repurchase agreements.

                      BALLSTON BANCORP, INC. AND SUBSIDIARY

              NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS


NOTE 1 - BASIS OF PRESENTATION:

In the opinion of management, the accompanying unaudited consolidated financial
statements reflect all adjustments (which include normal recurring adjustments)
necessary to present fairly the financial position as of March 31, 1998 and
1997, and the results of operations, comprehensive income and cash flows for the
three months ended March 31, 1998 and 1997. These unaudited consolidated
financial statements should be read in conjunction with the consolidated
financial statements and notes for the year ended December 31, 1997. The results
of operations for the three months ended March 31, 1998 are not necessarily
indicative of the operating results which may be achieved for the full fiscal
year.

NOTE 2 - MERGER:

On March 11, 1998,  Ballston entered into the Agreement and Plan of Merger,  and
the related Plan of Merger  (collectively,  the "Merger Agreement")  pursuant to
which Ballston will be merged (the "Merger") with and into MainStreet Financial
Corporation, formerly MainStreet  BankGroup Incorporated  ("MSBC").  Under the
terms of the Merger Agreement,  each share of common stock, par value $0.20 per
share, of Ballston will be converted into that portion  of a share  of MSBC
common  stock  having a  market  value of  $12.04, provided  that a minimum of
0.4025  share and a maximum of 0.4920  share of MSBC common stock will be issued
for each share of Ballston common stock.

Consummation  of the Merger is subject,  among other things,  to the approval of
the Merger  Agreement by the  requisite  vote of Ballston  shareholders  and the
receipt  of  all  requisite  regulatory  approvals  and  satisfaction  of  other
conditions contained in the Merger Agreement.  It is anticipated that the Merger
will be  accounted  for as a  pooling  of  interests  under  generally  accepted
accounting principles.

In connection with the Merger Agreement,  MSBC and Ballston entered into a Stock
Option  Agreement,  dated as of March 11,  1998 (the  "Option  Agreement").  The
Option  Agreement  provides  that MSBC shall have the option to  purchase  up to
322,275 of the authorized,  but unissued, shares of Ballston's common stock at a
price of $8.64 per share, only upon the occurrence of certain specified events.

Ballston has agreed to pay a transaction fee in connection with the Merger to an
investment  banking firm. Under the terms of the agreement,  the fee is equal to
0.5% of the aggregate  transaction  price.  A substantial  portion of the fee is
contingent upon the consummation of the Merger.  Fees to that firm for the three
months ended March 31, 1998 totaled $34,375 and are included in merger expenses.

NOTE 3 - NET INCOME PER COMMON SHARE:

Net income per common  share is computed  using the weighted  average  number of
common shares outstanding during the year. The weighted average number of shares
was 1,619,474 for the three months ended March 31, 1998 and 1997.


                                       12

NOTE 4 - INCOME TAXES:

Income tax expense  differs from that computed at the statutory  Federal  income
tax rate for the three  months ended March 31,  1998,  primarily  due to certain
merger related expenses not being deductible for income tax purposes.

NOTE 5 - NEW ACCOUNTING PRONOUNCEMENTS:

Statement of Financial  Accounting  Standards No. 130, "Reporting  Comprehensive
Income" was issued in June 1997.  This  statement is effective  for fiscal years
beginning after December 15, 1997 and  reclassification of financial  statements
for  earlier  periods  provided  for  comparative  purposes  is  required.  This
statement  establishes  standards  for  reporting  and display of  comprehensive
income and its  components  in the  financial  statements.  The objective of the
statement is to report a measure of all changes in equity of an enterprise  that
results from  transactions  and other  economic  events of the period other than
transactions  with owners.  Ballston adopted this statement in the first quarter
of 1998,  and has  included  its  comprehensive  income in a separate  financial
statement as part of its unaudited consolidated financial statements.

NOTE 6 - SUPPLEMENTAL DISCLOSURES OF CASH FLOW INFORMATION:

                          Independent Auditors' Report






To the Board of Directors and Shareholders of
Ballston Bancorp, Inc.


We have  audited  the  accompanying  consolidated  statements  of  condition  of
Ballston Bancorp,  Inc. and Subsidiary as of December 31, 1997 and 1996, and the
related consolidated  statements of income, changes in stockholders' equity, and
cash  flows  for the  years  then  ended.  These  financial  statements  are the
responsibility of the Corporations' 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 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 Ballston Bancorp,
Inc. and  Subsidiary as of December 31, 1997 and 1996,  and the results of their
operations  and their cash flows for the years  then  ended in  conformity  with
generally accepted accounting principles.

                      BALLSTON BANCORP, INC. AND SUBSIDIARY

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


NOTE 1 - SIGNIFICANT ACCOUNTING POLICIES:

A summary of  significant  accounting  policies of Ballston  Bancorp,  Inc.  and
Subsidiary (the "Corporations") is as follows:

BASIS OF ACCOUNTING:

The accompanying  consolidated  financial  statements are prepared in accordance
with generally accepted  accounting  principles and conform to general practices
within the banking industry.

PRINCIPLES OF CONSOLIDATION:

The  accompanying  consolidated  financial  statements  include the  accounts of
Ballston Bancorp, Inc. ("Ballston") and its wholly-owned subsidiary, The Bank of
Northern Virginia ("The Bank").  All significant  intercompany  transactions and
balances have been eliminated.

NATURE OF OPERATIONS:

Ballston  was  organized  under the laws of the State of  Delaware to serve as a
bank  holding  company.  The Bank  operates as a commercial  bank in  Arlington,
Virginia.  Its primary  deposit base and principal  real estate  lending  market
includes Arlington and the surrounding area in Northern Virginia.

USE OF ESTIMATES:

The preparation of financial  statements in conformity  with generally  accepted
accounting principles requires management to make estimates and assumptions that
affect  the  reported  amounts  of assets  and  liabilities  and  disclosure  of
contingent  assets and  liabilities at the date of the financial  statements and
the reported amounts of income and expenses during the reporting period.  Actual
results could differ from those estimates.

Material  estimates that are  particularly  susceptible  to  significant  change
relate to the  determination  of the allowance for loan losses and the valuation
of real estate  acquired in connection  with  foreclosures or in satisfaction of
loans. In connection with the determination of the allowance for loan losses and
the  valuation  of  foreclosed  real  estate,   management  obtains  independent
appraisals  for  significant   properties.   While   management  uses  available
information  to recognize  losses on loans and  foreclosed  real estate,  future
additions to the allowance may be necessary  based on changes in local  economic
conditions. Federal, state and local governments employ a significant portion of
the Northern Virginia area labor force.  Adverse changes in economic  conditions
could have a direct impact on the  collectibility  of The Bank's loan  portfolio
and the recovery of a substantial  portion of the carrying  amount of foreclosed
real estate.  In addition,  regulatory  agencies,  as an integral  part of their
examination  process,  periodically  review The Bank's allowance for loan losses
and valuation of foreclosed  real estate.  Such agencies may require The Bank to
recognize  additions to the allowance based on their judgments about information
available to them at the time of their examination. Because of these factors, it
is  reasonably  possible that the allowance for loan losses and the valuation of
foreclosed  real  estate  may  change  materially  in the  near  term.


                                       21

NOTE 1 - SIGNIFICANT ACCOUNTING POLICIES: (Cont'd.)

CASH AND CASH EQUIVALENTS:

For financial  reporting  purposes,  cash and cash equivalents  includes cash on
hand, amounts due from banks (including cash items in process of clearing),  and
federal funds sold.  Cash flows from interest  bearing  deposits with  financial
institutions,  loans,  deposits and securities sold under repurchase  agreements
are reported net.

INVESTMENT SECURITIES:

Held-to-maturity securities are those securities which the Corporations have the
ability and intent to hold until  maturity  and are carried at  amortized  cost.
Available-for-sale  securities  represent  those  securities  not  classified as
held-to-maturity  and are stated at fair  value.  Unrealized  holding  gains and
losses,  net of the  related  deferred  tax effect,  are  reported as a separate
component of stockholders' equity.

Premiums and discounts on  investments  in debt  securities  are amortized  over
their  contractual  lives.  The  method of  amortization  results  in a constant
effective yield on those  securities  which  approximates  the interest  method.
Realized  gains and losses are  included  in income  and are  determined  by the
specific-identification method.

LOANS:

Loans are stated at the amount of unpaid principal  reduced by unearned fees and
an allowance for loan losses.

The allowance for loan losses is  maintained at a level which,  in  management's
judgment,  is adequate to absorb credit losses  inherent in the loan  portfolio.
The  amount  of  the  allowance  is  based  on  management's  evaluation  of the
collectibility  of the loan  portfolio,  including the nature of the  portfolio,
credit concentrations,  trends in historical loss experience,  specific impaired
loans,  and economic  conditions.  Allowances  for impaired  loans are generally
determined  based on collateral  values or the present  value of estimated  cash
flows.  The  allowance  for loan losses is  increased  by a  provision  for loan
losses,  which is  charged  to  expense,  and  reduced  by  charge-offs,  net of
recoveries.

Interest is accrued daily on the  outstanding  balances.  Accrual of interest is
discontinued on a loan when management  believes,  after considering  collection
efforts and other factors,  that the borrower's financial condition is such that
collection of interest is doubtful.

Loan origination fees and certain direct  origination  costs are capitalized and
recognized as an adjustment of the yield on the related loan.

FORECLOSED REAL ESTATE HELD FOR SALE:

Foreclosed  real  estate held for sale,  includes  properties  acquired  through
foreclosure or in full or partial  satisfaction of the related loan.  Foreclosed
real estate is  initially  recorded at the lower of fair value,  less  estimated
selling  costs,  or  cost,  at  the  date  of  foreclosure.  After  foreclosure,
valuations are periodically performed by management and the assets are stated at
the lower of carrying value or fair value, less estimated selling costs.

NOTE 1 - SIGNIFICANT ACCOUNTING POLICIES:  (Cont'd.)

BANK PREMISES AND EQUIPMENT:

Bank premises and equipment is stated at cost less accumulated  depreciation and
amortization.  Leasehold  improvements are amortized on the straight-line method
over the shorter of the estimated  useful lives of the improvements or the terms
of  the  related   leases.   Furniture  and  equipment  is  depreciated  on  the
straight-line method over the estimated useful lives of the assets.

ADVERTISING:

Advertising  costs are expensed as incurred.  These expenses  amounted to $9,758
and $14,843 for the years ended  December 31, 1997 and 1996,  respectively,  and
are  included in other  operating  expenses in the  consolidated  statements  of
income.

INCOME TAXES:

The  Corporations  file a consolidated  Federal income tax return.  Deferred tax
assets and liabilities  are recognized for the expected future tax  consequences
of  temporary  differences  between  the  carrying  amounts and the tax bases of
assets and  liabilities.  As changes in tax laws or rates are enacted,  deferred
tax assets and liabilities are adjusted through the provision for income taxes.

NET INCOME PER COMMON SHARE:

Effective December 31, 1997, Ballston adopted Statement of Financial  Accounting
Standards No. 128,  "Earnings per Share".  The adoption of this statement had no
effect on Ballston.  Net income per common share is computed  using the weighted
average  number of common  shares  outstanding  during  the year.  The  weighted
average number of shares was 1,619,474 for both 1997 and 1996.

OFF-BALANCE-SHEET FINANCIAL INSTRUMENTS:

In the ordinary course of business,  The Bank 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.

The net deferred  tax assets are  included in other  assets in the  consolidated
statements of condition. Management has adopted a policy to maintain a valuation
allowance to completely  offset any deferred tax asset  resulting  from possible
future  realization  of net operating  loss  carryforwards  for state income tax
purposes.


NOTE 10 - RETIREMENT PLAN:

The  Bank  has a  defined  contribution  401(k)  retirement  plan  which  covers
employees that meet certain age and length of service  requirements.  Under this
plan,  The  Bank  will  match  the  employees'  contributions  up to  6% of  the
employees'  compensation.  For the years ended  December 31, 1997 and 1996,  The
Bank's contribution amounted to $18,000 and $25,314, respectively.

NOTE 11 - COMMITMENTS AND CONTINGENCIES:

FINANCIAL INSTRUMENTS WITH OFF-BALANCE-SHEET RISK:

The Bank is a party to financial instruments with  off-balance-sheet risk in the
normal course of business to meet the financing  needs of its  customers.  These
financial  instruments  include commitments to extend credit and standby letters
of credit.  Those instruments  involve,  to varying degrees,  elements of credit
risk not recognized in the  consolidated  statements of condition.  The contract
amounts of those  instruments  reflect the extent of involvement The Bank has in
particular classes of financial instruments.

The Bank'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.
The Bank uses the same credit  policies in making  commitments  and  conditional
obligations as it does for on-balance-sheet instruments.

A summary of The  Bank's  commitments  as of  December  31,  1997 and 1996 is as
follows:

                                                      1997              1996
                                                 -----------      ------------
         Commitments to extend credit            $10,452,000      $ 10,794,000
         Standby letters of credit                   944,000         1,002,000


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
generally  have fixed  expiration  dates or other  termination  clauses  and may
require  payment of a fee.  Since  commitments  frequently  expire without being
drawn upon, the total  commitment  amounts do not necessarily  represent  future
cash  requirements.  The Bank evaluates each customer's  credit  worthiness on a
case-by-case  basis. The amount of collateral  obtained,  if deemed necessary by
The Bank upon extension of credit, is based on management's credit evaluation of
the  party.  Collateral  held  varies,  but  may  include  accounts  receivable,
marketable  securities,  inventory,  property and  equipment,  residential  real
estate and income-producing commercial properties.

Standby  letters of credit  are  conditional  commitments  issued by The Bank to
guarantee the performance of a customer to a third party.  Those  guarantees are
primarily  issued to  support  public and  private  borrowing  arrangements  and
generally  expire  within one year from  issuance.  The credit risk  involved in
issuing  letters of credit is essentially the same as that involved in extending
loan  facilities to customers.  Collateral held varies as specified above and is
required in instances which The Bank deems necessary.

LITIGATION:

The Corporations occasionally are defendants in certain claims and legal actions
arising in the ordinary course of business. It is the opinion of management that
the disposition of these matters will not have a material  adverse effect on the
Corporations' financial position.

NOTE 11 - COMMITMENTS AND CONTINGENCIES:  (Cont'd.)

OTHER:

The  Corporations  have  an  ongoing  program  designed  to  ensure  that  their
operational  and  financial  systems will not be adversely  affected by the year
2000 software failures due to processing errors arising from calculations  using
the year 2000 data.  While the  Corporations  believe they are doing  everything
technologically possible to assure year 2000 compliance, they are to some extent
dependent upon vendor  cooperation.  The Corporations  are requiring  vendors of
their computer systems and software to represent that the products  provided are
or will be year  2000  compliant  and have  planned  a program  of  testing  for
compliance. It is recognized that any year 2000 compliance failures could result
in additional expense to the Corporations.

The Bank has a contract with an entity, whereby such entity will perform certain
processing  work  necessary to The Bank's  operations for a period of five years
expiring in 2000. The contract provides for automatic  five-year  renewals until
it is terminated. There are no minimum annual fees.

NOTE 12 - RELATED PARTY TRANSACTIONS:

The  Corporations  have  had,  and  may be  expected  to  have  in  the  future,
transactions  in the ordinary course of business with  stockholders,  directors,
officers and  affiliated  entities in which they are  principal  owners,  all of
which  have  been,  in the  opinion  of  management,  on the same terms as those
prevailing at the time for comparable transactions with others.

Loans with related  parties  totaled  $3,095,108  and $3,628,012 at December 31,
1997 and 1996, respectively.

Professional  fees  were paid to firms in which  stockholders  of  Ballston  are
principals. These fees totaled $283,401 and $66,859 for the years ended December
31, 1997 and 1996, respectively.

NOTE 13 - STOCK OPTION AGREEMENTS:

In 1992,  Ballston granted options to purchase 75,000 shares of its common stock
to two key employees of The Bank. The options could only be exercised if certain
performance measures were met by The Bank or if there was a change in control of
Ballston or The Bank, as defined in the  agreements.  The exercise  price of the
options was $3.76 per share. These options expired August 17, 1997 without being
exercised.

NOTE 14 - DIVIDEND RESTRICTIONS:

Banking  regulations  limit the amount of dividends that may be paid by The Bank
without prior regulatory  approval.  At December 31, 1997, The Bank had retained
earnings of approximately $2,071,000 available for the payment of dividends.




                                       31

NOTE 15 - REGULATORY MATTERS:

The Bank is subject to various regulatory capital  requirements  administered by
federal  banking  agencies.  Failure to meet minimum  capital  requirements  can
initiate certain mandatory - and possibly  additional  discretionary  actions by
regulators  that,  if  undertaken,  could have a direct  material  effect on The
Bank's  financial   statements.   Under  capital  adequacy  guidelines  and  the
regulatory  framework for prompt corrective  action, The Bank must meet specific
capital  guidelines  that involve  quantitative  measures of The Bank's  assets,
liabilities,  and certain off-balance-sheet items as calculated under regulatory
accounting  practices.  The Bank's capital amounts and  classification  are also
subject to  qualitative  judgments  by the  regulators  about  components,  risk
weightings, and other factors.

Quantitative  measures  established  by  regulation to ensure  capital  adequacy
require The Bank to maintain  minimum amounts and ratios (set forth in the table
below)  of  Total  and  Tier  I  Capital  (as  defined  in the  regulations)  to
risk-weighted assets (as defined), and of Tier 1 Capital (as defined) to average
assets (as defined). Management believes, as of December 31, 1997, that The Bank
meets all capital adequacy requirements to which it is subject.

The most recent  notification from the Board of Governors of the Federal Reserve
System  categorized The Bank as well capitalized under the regulatory  framework
for prompt corrective  action.  To be categorized as well capitalized,  The Bank
must maintain minimum total risk-based,  Tier I risk-based,  and Tier I leverage
ratios as set forth in the table.  There are no  conditions or events since that
notification that management believes have changed The Bank's category.

The Bank's actual capital amounts and ratios are also presented in the table.

NOTE 17 - SUBSEQUENT EVENT (UNAUDITED):

On March 11, 1998,  Ballston entered into the Agreement and Plan of Merger,  and
the related Plan of Merger  (collectively,  the "Merger Agreement")  pursuant to
which Ballston will be merged (the "Merger") with and into MainStreet Financial
Corporation, formerly MainStreet  BankGroup Incorporated  ("MSBC").  Under the
terms of the Merger Agreement,  each share of common stock, par value $0.20 per
share, of Ballston will be converted into that portion  of a share  of MSBC
common  stock  having a  market  value of  $12.04, provided  that a minimum of
0.4025  share and a maximum of 0.4920  share of MSBC common stock will be issued
for each share of Ballston common stock.

Consummation  of the Merger is subject,  among other things,  to the approval of
the Merger  Agreement by the  requisite  vote of Ballston  shareholders  and the
receipt  of  all  requisite  regulatory  approvals  and  satisfaction  of  other
conditions contained in the Merger Agreement.  It is anticipated that the Merger
will be  accounted  for as a  pooling  of  interests  under  generally  accepted
accounting principles.

In connection with the Merger Agreement,  MSBC and Ballston entered into a Stock
Option  Agreement,  dated as of March 11,  1998 (the  "Option  Agreement").  The
Option  Agreement  provides  that MSBC shall have the option to  purchase  up to
322,275 of the authorized,  but unissued, shares of Ballston's common stock at a
price of $8.64 per share, only upon the occurrence of certain specified events.

Ballston has agreed to pay a transaction fee in connection with the Merger to an
investment  banking firm. Under the terms of the agreement,  the fee is equal to
0.5% of the aggregate  transaction  price.  A substantial  portion of the fee is
contingent upon the consummation of the Merger.

                     INFORMATION NOT REQUIRED IN PROSPECTUS

Item 20.  Indemnification of Officers and Directors

         MSBC's Articles of Incorporation  implement the provisions of the VSCA,
which  provide for the  indemnification  of MSBC's  directors  and officers in a
variety of  circumstances,  which may include  indemnification  for  liabilities
under the Securities  Act.  Under sections  13.1-697 and 13.1-702 of the VSCA, a
Virginia  corporation  generally is  authorized  to indemnify  its directors and
officers in civil or criminal  actions if they acted in good faith and  believed
their conduct to be in the best interests of the corporation and, in the case of
criminal  actions,  had no  reasonable  cause to believe  that the  conduct  was
unlawful.  MSBC's Articles of Incorporation require indemnification of directors
and officers  with respect to certain  liabilities,  expenses and other  amounts
imposed upon them be reason of having been a director or officer,  except in the
case of willful  misconduct  or a knowing  violation of criminal  law. MSBC also
carries insurance on behalf of directors, officers, employees or agents that may
cover  liabilities  under the Securities  Act. In addition,  the VSCA and MSBC's
Articles of  Incorporation  eliminate  the liability of a director or officer of
MSBC in a shareholder or derivative  proceeding.  This  elimination of liability
will not apply in the event of willful  misconduct or a knowing violation of the
criminal law or any federal or state  securities  law.  Sections  13.1-692.1 and
13.1-696 to -704 of the VSCA are hereby incorporated herein by reference.

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

                           amendment  thereof)  which,  individually  or in  the
                           aggregate,  represent  a  fundamental  change  in the

     (b) The registrant hereby undertakes:

         (1)      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.

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

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

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

         Pursuant  to the  requirements  of the  Securities  Act  of  1933,  the
