Dear Common Stock Shareholders:

     You are cordially invited to attend the Special Meeting of 
Shareholders of Commerce Bank Corporation ("Bank") on --------- --, 
1997 at --:-- a.m., Eastern Time, at the main offices of the Bank at 9658 
Baltimore Avenue, College Park, Maryland, 20740.  This is a very 
important meeting regarding your investment in the Bank.

     The purpose of the meeting is to consider and vote upon the 
Agreement and Plan of Share Exchange, dated as of July 3, 1997, by and 
between the Bank and MainStreet BankGroup Incorporated ("BankGroup")  
(the "Agreement") pursuant to which, among other things, Bank will 
become a wholly owned subsidiary of BankGroup through an exchange of 
all the issued and outstanding shares of Common Stock of Bank for the 
right to receive Common Stock of BankGroup according to the Exchange 
Ratio (the "Share Exchange") as detailed in the Agreement.  In the Share 
Exchange, each share of Common Stock of the Bank will be converted into 
the right to receive shares of Common Stock of BankGroup, as described in 
the accompanying Proxy Statement/Prospectus.  Your Board of Directors 
unanimously recommends that you vote in favor of the Agreement and the 
Share Exchange, which the Board believes is in the best interests of 
shareholders of the Bank.

     Enclosed is a Notice of the Special Meeting of Shareholders, a Proxy 
Statement/Prospectus containing a discussion of the Agreement and the 
Share Exchange and a proxy card.  Please complete, sign and date the 
enclosed proxy card and return it as soon as possible in the envelope 
provided.

     If you decide to attend the Special Meeting, you may vote your 
shares in person whether or not you have previously submitted a proxy.  It 
is important that you understand that the Agreement and Share Exchange 
must be approved by the holders of at least two-thirds of all outstanding 
shares of Common Stock of the Bank, and that the failure to vote will have 
the same effect as a vote against the proposal.  On behalf of the Board, 
thank you for your attention to this important matter.

                              Alvin R. Maier

<PAGE>

to vote, in favor of the Share Exchange.  See "Ownership by Certain 
Beneficial Owners of Bank Common Stock."

     The Board of Directors of BankGroup has approved the Share Exchange 
as well as the redemption of outstanding Bank Preferred Stock and 
Warrants (the "Transaction").  See "Redemption of Bank Preferred Stock and 
Warrants".  Approval of the Transaction by BankGroup shareholders is 
not required by applicable law or regulation.  

Redemption of Bank Preferred Stock and Warrants 
   
     The Agreement provides that as part of the Transaction, the Bank shall 
seek to obtain from the holders of Bank Preferred Stock and Warrants, 
agreements with the Bank and for the benefit of BankGroup for such 
holders to redeem their Bank Preferred Stock and Warrants for shares of 
BankGroup Common Stock according to the Exchange Ratio and Warrant 
Redemption Ratio, as applicable, and subject to adjustment as detailed 
within the Agreement.  It is a condition to the Transaction (waivable by 
BankGroup) that the holder of Bank Preferred Stock and the holders of 
Warrants (with the possible exception of Warrants held by Joseph O. 
Hansen and any other Warrants as to which BankGroup shall have 
executed an express written waiver meeting certain requirements) enter into 
these agreements.  Pursuant to the Agreement and if separately agreed by 
the holder of the Bank Preferred Stock and by the holders of the Warrants 
(with the possible exception of certain excluded Warrants) at the Effective 
Time of the Share Exchange, as defined herein under the heading "The 
Transaction -- Effective Time of Share Exchange," each share of Bank 
Preferred Stock shall be redeemed and the holder thereof shall be entitled 
to receive therefor that number of shares of BankGroup Common Stock 
determined by the Exchange Ratio, subject to adjustment as set forth in the 
Agreement and each outstanding Warrant (with the possible exception of 
certain excluded Warrants) shall be redeemed and the holder thereof 
entitled to receive therefor that number of shares of BankGroup 
Common Stock determined by the Warrant Redemption Ratio, subject to 
adjustment as set forth in the Agreement. 
    
The Share Exchange
   
     Pursuant to the Agreement, at the Effective Time of the Share Exchange 
(as defined herein under the heading "The Transaction -- Effective 
Time of the Share Exchange") Bank will become a wholly owned 
subsidiary of BankGroup in accordance with the Agreement and Plan of 
Share Exchange.  At the Effective Time of the Share Exchange, each 
outstanding share of Bank Common Stock (other than Excluded Shares as 
defined in the Agreement) will be converted into the right to receive a 
number of shares of BankGroup Common Stock, determined by the 
Exchange Ratio, subject to adjustment as set forth in the Agreement.
    
                                  4
<PAGE>
    
The Exchange Ratio
   
     For the purpose of determining the Exchange Ratio, each share of Bank 
Common Stock (and for purposes of redemption each share of Bank 
Preferred Stock) has been valued at $52.00, the Common Stock Price Per 
Share, sometimes referred to as "Exchange Consideration." The number of 
shares of BankGroup Common Stock to be delivered for each share of Bank 
Common Stock (and in consideration of the redemption of each share of 
Bank Preferred Stock) will be determined by dividing $52.00 per share of 
Bank Common Stock (or per share of Bank Preferred Stock, as the case 
may be) by the average of the bid/ask price per share (the "Average BankGroup 
Stock Price") for BankGroup Common Stock as reported on the Nasdaq 
National Market for each of the 20 trading days preceding the later to occur 
of (i) the shareholder approval(s) contemplated by Paragraph A of Article 
VI of the Agreement and (ii) the financial institution regulatory approvals 
(but not the statutory waiting periods) contemplated by Paragraph B of 
Article VI of the Agreement (the "Exchange Ratio").  If such quotient is 
less than 2.059, the Exchange Ratio shall be 2.059.  If such quotient is 
greater than 2.506, the Exchange Ratio shall be 2.506.  The Exchange Ratio 
will be adjusted to reflect any consolidation, split-up, other subdivisions or 
combinations of BankGroup Common Stock, any dividend payable in 
BankGroup Common Stock, or any capital reorganization involving the 
reclassification of BankGroup Common Stock.  See "The Transaction --
Determination of Exchange Ratio and Warrant Redemption Ratio; Exchange of 
Bank Common Stock for BankGroup Common Stock."
    
The Warrant Redemption Ratio
   
     Each Warrant subject to redemption in the Transaction shall, by 
agreement between the holder and Bank, be redeemed at the Effective Time 
and the holder shall be entitled to receive for each such Warrant that 
number of shares of BankGroup Common Stock equal to the quotient 
obtained by dividing $31.00 by the Average BankGroup Stock Price 
("Warrant Redemption Ratio").  If the Warrant Redemption Ratio computed 
in accordance with the immediately preceding sentence is less than 1.228, 
the Warrant Redemption Ratio shall be 1.228 ("Lower Collar"); if the Warrant
Redemption Ratio computed in accordance with the immediately preceding
sentence is greater than 1.494, the Warrant Redemption Ratio shall be 1.494
("Upper Collar"); provided, however, that if the Warrant Redemption Ratio
determined in accordance with the immediately preceding clause equals either
the Lower Collar or the Upper Collar, the Warrant Redemption Ratio shall be
further adjusted, if necessary, so that shares of MSBC Common Stock to be
issued for each CB Warrant pursuant thereto shall be equal in value to the
difference obtained by subtracting $21.00 from the product of the Average
MSBC Share Price times the Exchange Ratio (as defined in Article II, Paragraph
B).

Recommendation of the Board of Directors of Bank;
Reasons for the Transaction

     The Transaction is intended to result in the Bank becoming a wholly 
owned banking subsidiary of BankGroup.  The Bank Board has determined 
that the Transaction is in the best interests of Bank, its shareholders, and 
Warrant holders.  The Bank Board was influenced by a number of factors in 
arriving at this determination, though it did not assign any specific or 
relative weight to these factors in its consideration.  Among the factors 
considered were:

     (i)   The Bank Board believes that the Exchange Ratio provides a fair 
           price to Bank's shareholders for their shares of Bank Common and 
           Preferred Stock, and that the Warrant Redemption Ratio provides a 
           fair price to Bank's Warrant holders for their Warrants.  Scott & 
           Stringfellow, Inc., Bank's financial advisor, concluded that the 
           consideration to be received by holders of Bank Common Stock,
           the holder of Bank Preferred Stock and the Warrant holders in 
           the Transaction was fair to bank shareholders from a financial 
           point of view.  See "The Transaction -- Opinion of Financial 
           Advisor."  
   
     (ii)  The Share Exchange is anticipated to be tax free for federal 
           income tax purposes for the shareholders of Bank Common Stock and the
           exchange of BankGroup Common Stock for Bank Preferred Stock is
           anticipated to be tax free for federal income tax purposes for the
           holder of Bank Preferred Stock (other than in respect to cash paid
           in lieu of fractional shares).
    
    (iii)  The Transaction will broaden the range of financial services and
           products which the Bank offers and enhance its ability to provide 
           credit and other financial products in its market area.

     (iv)  The Transaction will enhance the Bank's delivery system 
           capability, thus improving its services to its customers, 
           including enhancing response time to credit requests.

     (v)   The Transaction will strengthen the Bank's operational systems 
           and allow economies of scale to be achieved in administrative 
           and related functions which will be shared with other affiliates 
           of BankGroup.

     (vi)  The Bank Board's review of the provisions of the Agreement was 
           favorable.

     (vii) The Transaction will allow Bank to continue its community bank 
           philosophy. 

     Based on these matters, and such other matters as the Bank Board 
deemed relevant, the Bank Board unanimously adopted the Agreement as 
being in the best interests of Bank, its shareholders and its Warrant 
holders.

                                  6

     THE BANK BOARD RECOMMENDS THAT BANK COMMON STOCK SHAREHOLDERS
VOTE FOR APPROVAL OF THE PROPOSAL.

Effective Time of the Share Exchange

     The Share Exchange is expected to be consummated around November 
30, 1997, or as soon thereafter as practicable.  Subject to the terms and 
conditions set forth herein, including receipt of all required regulatory 
approvals, the Share Exchange shall become effective on the date and time 
the Articles of Share Exchange are accepted by the Maryland Department 
of Assessments and Taxation, (the "Share Exchange Effective Date").  Bank
and BankGroup each has the right, acting unilaterally, to terminate the
Agreement should the Share Exchange not be completed by December 31, 1997.
See "The Transaction -- Termination."

Rights of Appraisal
   
   Under the applicable provisions of the Maryland General Corporation Law,
each holder of Bank Common and Preferred stock will be entitled to demand and
receive payment of the fair value of his shares, if he (i) prior to or at the
meeting, files with the Bank a written objection to the Share Exchange, (ii)
does not vote in favor of the Share Exchange, and (iii) within 20 days after
Articles of Share Exchange have been accepted for record by the Maryland
Department of Assessments and Taxation (the "Department"), makes written demand
on Bank for payment of his shares, stating the number of shares for which
payment is demanded.  A direction in the stockholder's proxy to vote against
the Share Exchange will not in itself constitute a written objection or demand
that satisfies the requirements described above.  Any stockholder who fails to
comply with the requirements described above will be bound by the terms of the
Share Exchange.
    
     Bank will promptly deliver or mail to each objecting stockholder written
notice of the date of acceptance of the Articles of Share Exchange for record
by the Department.  Bank may also deliver or mail to each objecting stockholder
a written offer to pay for his stock at a price deemed by Bank to be the fair
value thereof.  Within 50 days after acceptance of the Articles of Share
Exchange for record by the Department, either Bank or any objecting stockholder
who has not received payment for his shares may petition the court in Prince
George's County, Maryland, for an appraisal to determine the fair value
of such shares.  If the court finds that an objecting stockholder is entitled
to appraisal of his stock, the court will appoint three disinterested appraisers
to determine the fair market value of such shares on terms and conditions the
court determines proper, and such appraisers will, within 60 days after
appointment (or such longer period as the) court may direct), file with the
court and mail to each party to the proceeding their report stating their
conclusion as to the fair value of such shares.  Within 15 days after the filing
of such report, any party may object to such report and request a hearing
thereon.  The court will, upon motion of any party, enter an order either
confirming, modifying or rejecting such report and, if confirmed or modified,
enter judgment directing the time within which payment will be made.  If the
appraisers' report is rejected, the court may determine the fair value of the
shares of the objecting stockholders or may remit the proceeding to the same or
other appraisers.  Any judgment entered pursuant to a court proceeding will
include interest from the date of the stockholder's vote on the action to which
objection was made.  Costs of the proceeding shall be determined by the court
and may be assessed against Bank or, under certain circumstances, the objecting
stockholder, or both.

                                  7
<PAGE>

     At any time after the filing of a petition for appraisal, the court may
require objecting stockholders to submit their certificates representing shares
to the clerk of the court for notation of the pendency of the appraisal
proceedings.  A stockholder demanding payment for shares will not have the right
to receive any dividends or distributions payable to holders of record after the
close of business on the date of the stockholders' vote and will cease to have
any rights as a stockholder with respect to such shares except the right to
receive payment of the fair value thereof.

Opinion of Financial Advisor

     Bank has received the opinion of Scott & Stringfellow, Inc.  ("Scott & 
Stringfellow") that the Exchange Consideration to be received by the 
holders of Bank Common Stock, the holder of Preferred Stock and the Warrant
Holders pursuant to the terms of the Agreement is fair to Bank shareholders
from a financial point of view.  Scott & Stringfellow's opinion is directed
only to the Exchange Consideration to be received by the holders of Bank
Common Stock, the holder of Preferred Stock and the Warrant Holders and does
not constitute a recommendation as to how such holders of Bank Common Stock
should vote at the Bank Shareholder Meeting or as to any other matter.  Scott
& Stringfellow will be paid a fee for its services at the closing of the Share
Exchange.  For additional information concerning Scott & Stringfellow 
and its opinion, see "The Transaction -- Opinion of Financial Advisor" and 
the opinion of such firm attached as Annex B to this Proxy Statement/
Prospectus.

Conditions to Consummation

     Consummation of the Share Exchange will be accomplished by a 
statutory share exchange resulting in the acquisition of Bank by 
BankGroup.  The Share Exchange is contingent upon the approvals of the 
Board of Governors of the Federal Reserve System (the "Federal Reserve 
Board"), the Maryland Commission of Financial Regulation and the Bureau of 
Financial Institutions of the Virginia State Corporation Commission 
("Virginia Bank Regulator"), which approvals have been applied for and are 
expected to be received.  The Share Exchange is also subject to other usual 
conditions.  See "The Transaction -- Conditions to Consummation of 
the Transaction."

Conduct of Business Pending the Transaction 

     Pursuant to the terms of the Agreement, Bank has agreed not to take 
certain actions relating to the operation of its business pending 
consummation of the Transaction, without the prior approval of 
BankGroup, except as otherwise permitted by the Agreement.  See "The 
Transaction -- Business of Bank Pending the Transaction."

Interests of Certain Persons in the Transaction

     Certain members of Bank's management and the Bank Board have 
interests in the Transaction in addition to their interests as shareholders 
of Bank generally.  These include, among other things, indemnification and 
directors' and officers' liability insurance for Bank directors and officers, 

                                  8
<PAGE>

eligibility of Bank employees for certain BankGroup employee benefits, 
and redemption of Warrants held by directors and officers.  See "The 
Transaction -- Interests of Certain Persons in the Transaction."

Resale of BankGroup Common Stock

     Shares of BankGroup Common Stock received in the Transaction will be 
freely transferable by the holders thereof, except for those shares held by 
those holders who may be deemed to be "affiliates" (generally including 
directors, certain executive officers and 10% or greater shareholders) of 
Bank or BankGroup under applicable federal securities laws.  See "Resale 
of BankGroup Common Stock."

Certain Federal Income Tax Consequences of the Transaction

     BankGroup and Bank have received an opinion (the "Opinion") of 
Flippin, Densmore, Morse, Rutherford & Jessee, counsel to BankGroup, to the
effect that for federal income tax purposes the proposed Share Exchange
and the proposed exchange of solely BankGroup Common Stock for Bank
Preferred Stock will qualify as a reorganization under 368(a)(1)(B) of the 
Internal Revenue Code of 1986 (the "Code"), and, consequently, that no
gain or loss will be recognized by Bank Common or Preferred shareholders
on the receipt of BankGroup Common Stock solely in exchange for their
Bank Common or Preferred Stock.  HOWEVER, THE OPINION ALSO STATES THAT
THE RECEIPT OF CASH BY A BANK SHAREHOLDER, INCLUDING THE RECEIPT OF
CASH BY A DISSENTING SHAREHOLDER AND THE RECEIPT OF CASH IN LIEU OF A
FRACTIONAL SHARE OF BANKGROUP COMMON STOCK, WILL BE A TAXABLE TRANSACTION
AND THE EXCHANGE OF BANK COMMON OF PREFERRED STOCK WARRANTS FOR BANKGROUP
COMMON STOCK WILL BE A TAXABLE TRANSACTION.  The Opinion is based on
the assumption that the Transaction as it relates to Bank Preferred Stock
and Warrants will be treated for federal income tax purposes as an
exchange of such Preferred Stock and Warrants for solely BankGroup common
stock as part of or pursuant to a plan of reorganization.  The Opinion
is also based on certain customary assumptions and representations
regarding, among other things, the lack of previous dealings between
BankGroup and Bank, the existing and future ownership of BankGroup Common
and Bank stock and Warrants and the future business plans for BankGroup.
The Opinion is not binding upon the Internal Revenue Service or any 
tax authority or 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 other tax authority.  The receipt
of substantially the same opinion as of the Share Exchange Effective
Date is a condition to the consummation of the Transaction.

     For a more complete description of the federal income tax 
consequences of the Transaction, see "The Transaction--Certain Federal
Income Tax Consequences."  Due to the individual nature of the tax
consequences of the Transaction, it is recommended that each Bank
shareholder or Warrant holder consult his or her own tax advisor 
concerning the tax consequences of the Transaction.

Market Prices Prior to Announcement of the Share Exchange

     The following is information regarding the last reported closing 
price per share of BankGroup Common Stock on the National Association 
of Securities Dealers, Inc.  National Market System on June 23, 1997, the

Comparative Per Share Data

     The following table presents historical and pro forma per share data 
for BankGroup, and historical and equivalent pro forma per share data 
for Bank.  The pro forma combined amounts give effect to an assumed 
Exchange Ratio of 2.059 shares of BankGroup Common Stock for each 
share of Bank Common Stock and Bank Preferred Stock and a Warrant 
Redemption Ratio of 1.228 shares of BankGroup Common Stock for each 
outstanding Warrant (assuming that all shares of Bank Preferred Stock and 
Warrants are redeemed in the Transaction) (based on the last sale price of 
BankGroup Common Stock on June 30, 1997 of $27.50).  The equivalent 
pro forma Bank share amounts allow comparison of historical information 
about one share of Bank Common Stock to the corresponding data about 
what one share of Bank 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 2.059 and a Warrant 
Redemption Ratio of 1.228 (ratably apportioned).  As discussed in "The 
Transaction -- Determination of Exchange Ratio and Warrant Redemption 
Ratio; Exchange of Bank Common Stock for BankGroup Common Stock," 
the final Exchange Ratio and Warrant Redemption Ratio will be determined 
based on the average of the bid/ask price per share for BankGroup 
Common Stock as reported on the Nasdaq National Market for each of the 
20 trading days preceding the later to occur of (i) the shareholder 
approval(s) contemplated by paragraph A of Article VI of the Agreement 
and (ii) the financial institution regulatory approvals (but not the 
statutory waiting periods) contemplated by paragraph B of Article VI of the 
Agreement.  The following table is based on the assumption that all issued 
and outstanding shares of Bank Common Stock and of Bank Preferred 
Stock and all Warrants are converted into shares of BankGroup Common 
Stock.  The Transaction is reflected under the pooling of interests method 
of accounting and proforma information is derived accordingly.  

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

                Management's Discussion and Analysis
         of Financial Condition and Results of Operations

          Six months ended June 30, 1997, compared with
                   six months ended June 30, 1996

Overview

Bank reported year-to-date earnings at June 30, 1997 of $458 thousand 
which compares to $398 thousand at June 30, 1996, an increase of $60 
thousand, or 15.08%.  These 1997 earnings produced a return on average 
assets and a return on average equity of 1.42% and 15.68%, respectively.   
The 1996 year-to-date earnings equated to a return on average assets and a 
return on average equity of 1.26% and 15.32%, respectively.  Net interest 
income and noninterest income increased over 1996 numbers and were 
offset somewhat by increases in noninterest expense.  The provision for 
loan losses declined significantly from the same period in 1996.

Net income for Bank in the second quarter of 1997 was $215 thousand 
compared to $218 thousand in the second quarter of 1996, a decrease of $3 
thousand, or 1.38%.  The 1997 quarterly income translates into a return on 

                                 17
<PAGE>

average assets and a return on average equity of 1.34% and 14.50%, 
respectively.  The 1996 income for the same period produced a return on 
average assets and a return on average equity of 1.12% and 13.62%, 
respectively.

Net Interest Income

Net interest income was $1.5 million year-to-date June 30, 1997, compared 
to $1.4 million for the same period in 1996, an increase of 5.87%.  Total 
interest income increased $20 thousand over prior year levels, while interest 
expense declined $64 thousand.  The net interest margin for the year-to-date 
earnings in 1997 and 1996 was 5.08% and 4.90%, respectively.

Declines in the average volume NOW accounts, $312 thousand, jumbo 
certificates of deposit, $353 thousand, and consumer certificates of deposit 
$1.2 million, were offset in part by an increase in the volume of money 
market deposits, $1.3 million, resulting in a net decline of interest 
expenses related to deposits of $42 thousand.  The volume of repurchase 
agreements also declined from the same period in 1996, approximately $1.2 
million, resulting in a decline in the related interest expense of 
approximately $24 thousand.

Net interest income for the second quarter of 1997 was $768 thousand in 
comparison to $739 thousand for the same period in 1996.   The largest 
component of the increased net income was a result of the decline in 
interest expense on repurchase agreements of $25 thousand for the quarter.  
Net interest margin for the second quarter of 1997 was 5.16% compared to 
4.99% for the second quarter of 1996.

Provision for Loan Losses

The provision for loan losses for year-to-date June 30, 1997 was $30 
thousand compared to $138 thousand June 30, 1996, a decline of $108 
thousand or 78.26%.  This year-to-date decline was divided between the 
first and second quarters, with $75 thousand in the first quarter and $33 
thousand in the second.  The decline was primarily due to the reserve being 
at an adequate level. 

Noninterest Income

Total noninterest income year-to-date was $347 thousand compared to $281 
thousand for the year to date 1996, an increase of $66 thousand, or 23.49%.  
The largest part of this variance was split between service charges on 
deposit accounts, $39 thousand, and collection fees, $24 thousand. 

                                 18
<PAGE>

Noninterest income for the second quarter of 1997 was $184 thousand 
compared to $142 thousand for the same period in 1996, an increase of $42 
thousand, or $29.58%.  This increase was also within service charges on 
deposit accounts and other fee income with variances of $28 thousand and 
$14 thousand, respectively.

Noninterest Expense

Total noninterest expense year-to-date June 30, 1997 was $1,047 thousand 
compared to $910 thousand for the same period in 1996, an increase of  
$137 thousand, or 15.05%.  Salaries and employee benefits accounted for 
$83 thousand of the increase.  The balance of the increase over 1996 could 
be found within legal fees and certain acquisition costs which had variances
of $34 thousand and $29 thousand, respectively.  These acquisition costs are
related to the proposed transaction with BankGroup Incorporated.

Total noninterest expense for the second quarter of 1997 was $544 thousand 
compared to $454 thousand for the same period in 1996, an increase of $90 
thousand, or 19.82%.  This increase can be found in the salaries and 
employee benefits category of $44 thousand, legal fees of $23 thousand, 
and acquisition fees, $29 thousand.

June 30, 1997 vs. December 31, 1996

Balance Sheet

Total assets at June 30, 1997 were $74.5 million, an increase of $5.2 million 
or 7.55%, from year end December 31, 1996.  The largest components of 
this variance is within Cash and Due from Banks and Fed Funds Sold, with 
increases of $2.5 million and $5.2 million, respectively.  

Loans, net of unearned income at June 30, 1997 were $44.6 million, a 
decline of $1.0 million from year end 1996.   This change was found 
primarily in the Commercial loan category, with a volume decrease of $1.1 
million from year end.

Total deposits at June 30, 1997 were $ 58.7 million compared to $54.2 
million at December 31, 1996, an increase of $4.5 million or 8.34%.  The 
variances from year end were within the demand deposit category with a 
positive variance of $5.0 million.  There was also a positive variance of 
$2.5 million in the time deposits greater than $100 thousand category, with 
an equal offset within the money market deposits.  Other time deposits 
declined approximately $1.5 million from December 31, 1996.

Nonperforming assets, consisting entirely of nonperforming loans, were 
$754 thousand at June 30, 1997, compared to $216 thousand at December 

                                 19
<PAGE>

31, 1996.  Nonaccrual loans comprised $681 thousand of the nonperforming 
loans at June 30, 1997 compared to $216 thousand at December 31, 1996.  
The net charge-off ratio at June 30, 1997 was .17%, up from .09% at 
December 31, 1996.  The allowance for loan losses to actual loans, net of 
unearned income, was 1.57% and 1.55% at June 30, 1997 and December 
31, 1996, respectively.

Total Shareholders' Equity

Total shareholders' equity, excluding unrealized gains (losses) on securities, 
at June 30, 1997 was $6.1 million, an increase of $.5 million from year-end 
December 31, 1996.  At June 30, 1997, the Tier I Leverage and Total Risk-
Based Capital ratios were 8.13% and 14.47%, respectively.  The same ratios 
at December 31, 1996 were 8.08% and 13.68%, respectively.

                Management's Discussion and Analysis
         of Financial Condition and Results of Operations

            Year ended December 31, 1996 compared with
                   year ended December 31, 1995

Overview

Net income for 1996 was $.9 million in comparison to $.6 million in 1995, 
an increase of $.3 million, or 44.28%.  The return on average assets and 
return on average equity for 1996 were 1.42% and 17.01%, respectively.  
For the comparable period in 1995, the return on average assets and the 
return on average equity were 1.22% and 12.76%, respectively.

Net Interest Income

Net interest income for 1996 was $3.0 million in comparison to $2.6 million 
in 1995, an increase of $.4 million, or 14.67%.  Both interest income and 
interest expense increased.  Average interest earning assets increased $12.3 
million while average interest bearing deposits increased $7.6 million and 
average short term borrowings increased $1.9 million.  The net interest 
margin declined to 4.97% in 1996 compared to 5.45% in 1995 because of 
an increase of 16.58% in interest expense versus a 15.41% increase in 
interest income.  Of the $12.3 million increase in interest earning assets, 
only $3.4 million was in loan volume.  The remainder of the increase in
interest income was from lower earning federal funds sold and securities.
This shift from loans to lower interest earning deposits was a primary
factor in the decline of the net interest margin.  Some of the increase
in interest expense resulted from the shift in deposits from lower
yielding accounts to higher yielding certificates of deposit along
with additional borrowings.

Provision for Loan Losses

A provision for loan losses is charged to earnings for the purpose of 
establishing an allowance for loan losses.  Losses are, in turn, charged to 
this allowance rather than being reported as a direct expense.  The 
provision for loan losses for 1996 was $175 thousand compared to $306 
thousand in 1995, a decrease of 42.81%.  The 1995 expense was due to 
increased volumes and charge-offs.

Noninterest Income

Total noninterest income for 1996 was $589 thousand compared to $543 
thousand in 1995, an increase of 8.52%.  The increase in noninterest income 
was split between increases in deposit accounts along with other 
miscellaneous fee income.  

Noninterest Expense

Total noninterest expense for 1996 increased $77.7 thousand , or 4.25%, 
over the 1995 expense.   Salaries and employee benefits were the largest 
categories of increase at $144.5 thousand, or 15.14% over 1995 expense.  
Occupancy expense also increased in 1996 over 1995 expense $15.9 
thousand, or 6.68%.  These expenses were offset by declines in FDIC and 
state assessments along with other miscellaneous expenses.

Balance Sheet

Total assets at December 31, 1996 were $69.3 million, an increase of $4.6 
million, or 7.05% over total assets of $64.7 million at December 31, 1995.

Federal funds sold at December 31, 1996 were $6.1 million, a decline of 
$3.9 million from the $10.0 million at December 31, 1995.   Average 
federal funds sold, however, increased $4.3 million to $6.9 million for the 
1996 year in comparison to 1995.

Investment Securities

Period end total securities at December 31, 1996 increased $2.1 million, or 
22.45%, over the same period in 1995. At year end 1996, $4.0 million of 
securities were in the available for sale category and $7.5 million were in 
the held to maturity category.  At December 31, 1995, $4.5 million of 
securities were in the available for sale category and $4.9 million were in 
the held to maturity category.  The increase between the two years has been 
in the held to maturity category.  All securities at December 31, 1996 and 
1995 were U. S. Government securities and Federal Reserve Bank stock.    

                                 21

Loans and the Allowance for Loan Losses

Loans, net of unearned income at year-end 1996 were $45.6 million, an 
increase of  $4.8 million, or 11.86%.  Average loans, net of unearned 
income increased $3.4 million, or 8.82% over 1995.  During 1996, the ratio 
of net charge-offs to average loans, net of unearned income declined to 
 .09% compared to .32% in 1995.  At year-end 1996, the allowance for loan 
losses to nonperforming loans was 327.62% compared to 499.16% at year-
end 1995.  The allowance for loan losses to period-end loans at December 
31, 1996 and 1995 was 1.55% and 1.40%, respectively.  The allowance for 
loan losses is established based on a continual review of the overall loan 
portfolio.  Management believes the allowance for loan losses is adequate at 
year-end.

Other Assets

Other assets at year-end 1996 were $716 thousand compared to $736 
thousand at year-end 1995, a decline of $20 thousand, or 2.79%.  This was 
primarily due to the decline in bank premises and equipment, due to 
depreciation, along with accrued interest on securities and loans.  

Deposits

Total deposits at December 31, 1996 were $54.2 million compared to $53.2 
million at December 31, 1995, an increase of $1.0 million, or 1.83%.  
Average deposits for 1996, however, increased $10.2 million over 1995 
average volumes and were $50.8 million.  Interest bearing deposits 
comprised $7.6 million of the year to year increase.  These increases were 
attributed to bank growth.  

Borrowings
  
Borrowings at December 31, 1996 were $9.3 million compared to $6.0 
million at December 31, 1995, an increase of $3.3 million, or 55.10%.  
These borrowings consisted of demand repurchase agreements and U. S. 
Treasury demand notes of $8.8 million and $.5 million, respectively, at 
December 31, 1996.  At December 31, 1995, the demand repurchase 
agreements and U. S. Treasury demand notes were $5.5 million and $.5 
million, respectively.

                                 22

Shareholders' Equity

Shareholders' equity at December 31, 1996 was $5.6 million compared to 
$5.0 million at year-end 1995.  Unrealized losses, net of tax, on securities 
were $4 thousand at year-end 1996 compared to $7 thousand at year-end 
1995.

Effects of Inflation

Over the past few years, the rate of inflation has been relatively mild.  
Loan and deposit rates normally increase along with inflation.  Financial 
statements presented reflect these effects.

                          GENERAL INFORMATION

     This Proxy Statement/Prospectus is furnished in connection with the 
solicitation of proxies by the Bank Board, to be voted at the Bank 
Shareholder Meeting to be held at the main offices of the Bank located at 
9658 Baltimore Avenue, College Park, Maryland, 20740, on ------------ --, 
1997, at --:-- a.m., Eastern Time and at any adjournment thereof.  At the 
Bank Shareholder Meeting, shareholders will consider and vote upon the 
Agreement, pursuant to which BankGroup will acquire Bank through a 
Share Exchange.  Only shareholders of record of Bank at the  close of 
business on ------------- --, 1997 are entitled to notice of and to vote at the 
Bank Shareholder Meeting.  This Proxy Statement/Prospectus is being 
mailed to all such holders of record of Bank Common Stock on or about 
- ----------- --, 1997.

     Holders of Bank Common Stock are entitled to one vote for each share 
standing in such holder's name on the books of Bank.  The affirmative vote 
of the holders of at least two-thirds of the outstanding shares entitled to 
vote is required for approval of the Share Exchange.  

     Under rules of the National Association of Securities Dealers, Inc., the 
proposal to adopt the Agreement is considered a "non-discretionary item" 
whereby brokerage firms may not vote in their discretion on behalf of their 
clients if such clients have not furnished voting instructions.  Abstentions 
and such broker "non-votes" will be considered in determining the presence 
of a quorum at the Special Meeting but will not be counted as a vote cast for 
a proposal.  Because the proposal to adopt the Agreement is required to be 
approved by the holders of two-thirds of the outstanding shares of Bank 
Common Stock, abstentions and broker "non-votes" will have the same 
effect as a vote against this proposal.  

                                 23
<PAGE>

     The proxies solicited hereby, if properly signed and returned and not 
revoked prior to their use, will be voted in accordance with the instructions 
given thereon by the shareholders.  If no instructions are so specified, the 
proxies will be voted FOR the proposed Share Exchange.  Any shareholder 
giving a proxy has the power to revoke it at any time before it is exercised 
by (i) filing written notice of revocation addressed to Alvin R.  Maier, 
Chairman, Commerce Bank, 9658 Baltimore Avenue, College Park, 
Maryland 20740; (ii) submitting a duly executed proxy bearing a later date; 
or (iii) appearing at the Bank Shareholder Meeting and notifying the 
Secretary of his or her intention to vote in person.  Attendance at the 
Special Meeting will not, in and of itself, constitute revocation of a proxy.  
Proxies solicited by this Proxy Statement/Prospectus may be exercised only 
at the Bank Shareholder Meeting and any adjournment of the Bank 
Shareholder Meeting and will not be used for any other meeting.

     The accompanying proxy is being solicited by the Bank Board.  The cost 
of such solicitation will be borne by Bank.  In addition to the use of the 
mails, proxies may be solicited by personal interview, telephone or telegram 
by directors, officers and employees of Bank or BankGroup without 
additional compensation.  Arrangements may also be made with brokerage 
houses and custodians, nominees and fiduciaries for forwarding of 
solicitation material to beneficial owners of stock held of record by such 
persons and obtaining proxies from the beneficial owners of Bank Common 
Stock entitled to vote at the Special Meeting, and Bank will reimburse such 
persons for their reasonable expenses incurred in doing so.

     Under Maryland law, the purpose of the meeting must be included in the 
notice of the special meeting.

     This Prospectus will also be used by the Bank Board in their 
solicitation of agreements by the holders of all Bank Preferred Stock and 
Bank Warrants to redeem their Preferred Stock and Warrants for 
BankGroup Common Stock according to the ratios set forth within 
the Agreement.  See "Redemption of Bank Preferred Stock and Warrants."

     As of the Record Date, directors and executive officers of Bank and 
their affiliates beneficially owned a total of 77,836 shares (representing 
40.494% of the outstanding shares of Bank Common Stock), and the 
directors of BankGroup owned no Bank Common Stock.  Bank directors have 
agreed with BankGroup to recommend that Bank shareholders vote in favor of 
the Share Exchange and to vote shares beneficially owned by such directors, 
and shares with respect to which they have the power to vote, in favor of 
the Share Exchange.  See "Ownership of Certain Beneficial Owners of 
Bank Stock."
   
     For the reasons described herein, the Bank Board has adopted the 
Agreement, believes the Transaction is in the best interest of Bank, its 

                                 24
<PAGE>

shareholders and Warrant holders and recommends that Common Stock 
shareholders of Bank vote FOR approval of the Agreement.  The Bank 
Board additionally will seek to obtain agreements in compliance with the 
requirements of the Agreement from holders of Bank Preferred Stock and 
Warrants for the redemption of their Bank Preferred Stock and Warrants.  
Upon redemption, holders of Bank Preferred Stock and Warrants shall 
receive BankGroup Common Stock according to the Exchange Ratio (as to 
shares of Bank Preferred Stock) and Warrant Redemption Ratio (as to  
Warrants) set forth in the Agreement.  In making its recommendation, the 
Bank Board considered, among other things, the opinion of Scott & 
Stringfellow that the Exchange Consideration was fair to Bank  
shareholders and warrant holders from a financial point of view.  See
"The Transaction -- Recommendations of the Board of Directors of Bank;
Reasons for the Transaction," and "Opinion of Financial Advisor."

                         THE TRANSACTION
   
     The detailed terms of the Transaction are contained in the 
Agreement and Plan of Share Exchange, attached as Annex A to this Proxy 
Statement/Prospectus.  The following discussion describes the more 
important aspects of the Transaction and the terms of the Agreement.  
This description is not complete and is qualified by reference to the 
Agreement which is incorporated by reference herein.
    
Opinion of Financial Advisor

     Bank has retained Scott & Stringfellow to act as its financial advisor 
in connection with rendering a fairness opinion with respect to the  
Transaction.  Scott & Stringfellow is a full service investment banking and 
brokerage firm headquartered in Richmond, Virginia, that provides a broad 
array of services to corporations, financial institutions, individuals and

expertise and reputation in providing valuation and merger and acquisition 
and advisory services to financial institutions.  Scott & Stringfellow's

                                 25
<PAGE>
   
     On October 14, 1997, Scott & Stringfellow delivered a written opinion 
("Opinion") to the Bank Board that as of such date, the Exchange 
Consideration to be received by Bank Common Stock shareholders, by the
Bank Preferred Stock Shareholders and by the Warrant holders in 
BankGroup Common Stock was fair to the Bank Common Stock shareholders 
from a financial point of view.  No instructions or limitations were given 
or imposed by the Bank Board upon Scott & Stringfellow with respect to the 
investigations made or procedures followed by them in rendering the 
Opinion.
    
     The full text of the Opinion, which sets forth the assumptions made, 
matters considered and limits on the review undertaken, is set forth and 
attached hereto in Annex B to this Proxy Statement/Prospectus and is 
incorporated herein by reference.  Bank shareholders are urged to read the 
Opinion in its entirety.  The following is a summary of certain analyses 
performed by Scott & Stringfellow which were the bases of such Opinion.

     In developing its Opinion, Scott & Stringfellow reviewed and analyzed: 
(i) the Agreement; (ii) the Registration Statement and this Proxy Statement 
/Prospectus; (iii) the Bank's audited financial statements for the three 
years ended December 31, 1996; (iv) the Bank's unaudited financial statements
for the quarters ended June 30, 1997 and 1996, and other internal 
information relating to the Bank prepared by the Bank's management; (v) 
information regarding the trading market for the Bank Common Stock and 
the BankGroup Common Stock and the price ranges within which the 
respective stocks have traded; (vi) the relationship of prices paid to 
relevant financial data such as net worth, earnings, deposits and assets in 
certain bank and bank holding company mergers and acquisitions in Maryland in
recent years; (vii) BankGroup's annual reports to shareholders and its 
audited financial statements for the three fiscal years ended December 31, 
1996; and (viii) BankGroup's unaudited financial statements for the quarters 
ended June 30, 1997 and 1996 and other internal information relating to 
BankGroup prepared by BankGroup's management.  Scott & Stringfellow 
has discussed with members of the Bank's and BankGroup's management 
past and current business operations, the background of the Share 
Exchange, the reasons and basis for the Share Exchange, results of 
regulatory examinations, and the business and future prospects of the Bank 
and BankGroup individually and as a combined entity, as well as other 
matters relevant to its inquiry.  Scott & Stringfellow has conducted such 
other studies, analysis and investigations particularly of the banking 
industry, and considered such other information as it deemed appropriate, 
the material portion of which is described below. Finally, Scott & 
Stringfellow also took into account its assessment of general economic, 
market and financial conditions and its experience in other transactions, as 
well as its experience in securities valuations and knowledge of the 
commercial banking industry generally.

     Scott & Stringfellow relied without independent verification upon the 

                                 26
<PAGE>

accuracy and completeness of all of the financial and other information 
reviewed by it and discussed with it for purposes of its Opinion.  With 
respect to financial forecasts reviewed by Scott & Stringfellow in rendering 
its Opinion, Scott & Stringfellow assumed that such financial forecasts 
were reasonably prepared on the basis reflecting the best currently available 
estimates and judgment of the managements of the Bank and BankGroup as 
to the future financial performance of the Bank and BankGroup, 
respectively.  Scott & Stringfellow did not make an independent evaluation 
or appraisal of the assets or liabilities of the Bank and BankGroup nor was 
it furnished with any such appraisal.
   
     Scott & Stringfellow evaluated the financial terms of the Transaction 
using standard valuation methods, including a discounted cash flow 
analysis, a market comparable analysis, a comparable acquisition analysis, 
and a dilution analysis.
    
   
     Discounted Cash Flow Analysis.  Scott & Stringfellow performed a 
discounted cash flow analysis under various projections to estimate the fair 
market value of Bank Common Stock.  Among other things, Scott & 
Stringfellow considered a range of asset and earnings growth for the Bank 
of between 4.00% and 6.00% and a required equity capital level of 8.00% 
of total assets.  A range of discount rates from 11.50% to 13.50% was 
applied to the cash flows resulting from the projections during the first 
five years and the residual values.  The residual values were estimated by 
capitalizing the projected final year earnings by the discount rates, less 
the projected long-term growth rate of the Bank's earnings.  The discount 
rates, growth rates and capital levels were chosen based on what Scott & 
Stringfellow, in its judgment, considered to be appropriate taking into 
account, among other things, the Bank's past and current financial 
performance and conditions, the general level of inflation, rates of return 
for fixed income and equity securities in the marketplace generally and 
particularly in the banking industry.  The discounted cash flow analysis 
indicated a reference range of $37.50 to $50.00 per share for Bank Common 
Stock.  These values compare to the value of $52.00 and $60.74 per share of 
consideration for each share of Bank Common Stock as of the date of the
Agreement and October 9, 1997, respectively.  Accordingly, the present value
of Bank Common Stock was calculated at less than the value of the consideration
to be received from BankGroup pursuant to the Agreement.
    
   
    Comparable Acquisition Analysis.  Scott & Stringfellow compared the
relationship of prices paid to relevant financial data such as tangible net 
worth, assets, deposits and earnings in 12 bank and bank holding company 
mergers and acquisitions in Maryland since June 30, 1994, representing all 
such transactions known to Scott & Stringfellow to have occurred during 
this period with the proposed Share Exchange and found the consideration 
to be received from BankGroup to be within the relevant pricing ranges 
acceptable for such recent transactions. Specifically, based upon the most 
recent transactions announced in Maryland since June 30, 1994, other than 

                                 27
<PAGE>

the Bank Merger, the average price to tangible book value in these 
transactions is 2.19x, compared with 2.45x for the Share Exchange; the 
average price to earnings ratio was 21.27x, compared with 15.20x for the 
Share Exchange; the average deal price to deposits was 23.02%, compared 
with 26.00% for the Share Exchange; the average deal price to assets was 
19.63%, compared with 20.13% for the Share Exchange; and the average 
tangible book premium to core deposits was 13.51%, compared to 21.29% 
for the Share Exchange.  For purposes of computing the information with 
respect to the Share Exchange, $52.00 per share of consideration for each 
share of Bank Common Stock was used.
    
   
     Analysis of BankGroup and Bank Peer Group.  Scott & Stringfellow
analyzed the performance and financial condition of BankGroup relative to 
the Bank Peer Group consisting of Crestar Financial Corp., F&M National 
Corp., First Virginia Banks, Mason-Dixon Bankshares, Mercantile Bankshares,
Provident Bankshares and Union Bankshares. Certain financial information
compared was, among other things, information relating to tangible equity
to assets, loans to deposits, net interest margin, nonperforming assets,
total assets, and efficiency ratio.  Additional valuation information compared
for the trailing twelve month period ended June 30, 1997, and stock prices as
of October 9, 1997, was (i) price to tangible book value ratio which was 2.9x
for BankGroup, compared to an average of 2.46x for the Bank Peer Group, (ii)
price to last twelve months earnings ratio which was 20.6x for BankGroup,
compared to an average of 9.3x for the Bank Peer Group; (iii) return on
average assets which was 1.25% for BankGroup, compared to an average of 1.25%
for the Bank Peer Group; (iv) return on average equity which was 14.69% for 
BankGroup, compared to an average of 13.36% for the Bank Peer Group; 
and (v) a dividend yield of 1.92% for BankGroup, compared to an average 
of 2.19% for the Bank Peer Group.  Overall, in the opinion of Scott & 
Stringfellow, BankGroup's operating performance and financial condition 
were better than the Bank Peer Group average and BankGroup's market 
value was reasonable when compared to the Bank Peer Group.
    
   
     Dilution Analysis.  Based upon publicly available financial information 
on the Bank and BankGroup, Scott & Stringfellow considered the effect of 
the transaction on BankGroup and Bank. The immediate effect on 
BankGroup was to increase earnings per share by $0.02 or 0.33% and to 
increase book value per share by $0.02 or 0.26%. The effect on Bank under 
the same assumptions results in dividends per share of $1.15 and to 
increase the July 2, 1997 market value of Bank of $20.00 per share to 
$52.00 and $60.74, as of the date of the Agreement and October 9, 1997,
respectively.  This dilution analysis does not take into account the long-term
benefits for the combined companies resulting from the combination.  Scott 
& Stringfellow concluded from this analysis that the transaction would have 
a positive effect on the Bank and Bank Common Stock shareholders in that, 
historical dividends per share and market value per share of BankGroup 
Common Stock to be received by Bank shareholders would represent an 
increase, after giving effect of the exchange ratio.  See "Summary --
Comparative Per Share Data."

<PAGE>

     The summary set forth above includes the material factors considered, 
but does not purport to be a complete description of the presentation by 
Scott & Stringfellow to the Bank Board or of the analyses performed by 
Scott & Stringfellow.  The preparation of a fairness opinion involves 
various determinations as to the most appropriate and relevant methods of 
financial analysis and the application of these methods to the particular 
circumstances and, therefor, such an opinion is not readily susceptible to 
summary description.  Accordingly, notwithstanding the separate factors 
discussed above, Scott & Stringfellow believes that its analyses must be 
considered as a whole and that selecting portions of its analysis and of the 
factors considered by it, without considering all analyses and factors, could 
create an incomplete view of the evaluation process underlying its Opinion.  
As a whole, these various analyses contributed to Scott & Stringfellow's 
opinion that the terms of the Agreement are fair from a financial point of 
view to the Bank's shareholders.
   
     Pursuant to an engagement letter dated October 14, 1996 between the 
Bank and Scott & Stringfellow, in exchange for its services, Scott & 
Stringfellow will receive a fee equal to 1.00% of the total market value of 
the consideration received by Bank shareholders, which equates to a fee of 
approximately $165,000 and is payable at closing. 
    
Effective Time of the Share Exchange

     Subject to the terms and conditions set forth herein, including receipt 
of all required regulatory approvals, the Share Exchange shall become 
effective at the time Articles of Share Exchange relating to the Share 
Exchange are accepted and made effective by the Maryland State 
Department of Assessments and Taxation, (the "Effective Time of the Share
Exchange").  The Effective Time of the Share Exchange is expected to occur
on or about November 30, 1997, or as soon thereafter as is practicable.  Either
Bank or BankGroup may terminate the Agreement if the Share Exchange has not 
been consummated by December 31, 1997.

     Until the Effective Time of the Share Exchange, holders of Bank 
Common Stock will retain their rights as shareholders to vote on matters 
submitted to them by the Bank Board.

Lock-Up Option

     In addition to the Agreement, Bank and BankGroup have entered into an 
agreement, dated as of June 24, 1997, providing for BankGroup to have an 
option to purchase the Common Stock of Bank under certain conditions (the 

                                 29
<PAGE>

"Lock-up Option").  Specifically, the Lock-up Option provides that 
BankGroup shall have the option to purchase 19.9% of the issued and 
outstanding shares of Bank's Common Stock at a price of $26 per share.  
The Lock-up Option is exercisable only under limited circumstances.

     The Lock-up Option provides that BankGroup has an option to purchase 
Bank Common Stock only upon the occurrence of the following events:  (i) 
without BankGroup's prior written consent, Bank authorizes, recommends, 
publicly proposes or publicly announces an intention to authorize, recommend, 
propose or enter into an agreement with a third party to engage in (a) a 
merger, consolidation, share exchange or similar transaction; (b) the 
disposition by sale, lease, exchange or otherwise of its assets; or (c) the 
issuance, sale or other disposition of securities representing 20% or more 
of the voting power of Bank; or (ii) a third party any "group" (as defined
under the Exchange Act) acquires beneficial ownership or the right to 
acquire beneficial ownership of, 25% or more of outstanding Bank Common 
Stock.  BankGroup's right to exercise the Lock-up Option has not been 
triggered as of the date of this Proxy Statement/Prospectus.

     By Resolution dated June 23, 1997, the Bank Board exempted the Share 
Exchange from the special voting requirement for extraordinary actions 
contained in Sections 3-602(a) and 3-602(b) of the Corporations and 
Associations Article of the Annotated Code of Maryland which might 
otherwise have applied as a result of the grant of the Lock-up Option to 
BankGroup.  

Determination of Exchange Ratio and Warrant Redemption Ratio; 
Exchange of Bank Common Stock for BankGroup Common Stock

     Each share of Bank Common Stock issued and outstanding at the 
Effective Time of the Share Exchange shall, and without any action by the 
holder thereof, be converted into a number of shares of BankGroup 
Common Stock equal to the quotient (rounded to the nearest one one-
thousandth) of $52.00 divided by the average of the bid/ask price (the 
"BankGroup Stock Price") for BankGroup Common Stock as reported on 
the Nasdaq National Market for the 20 trading days preceding the later to 
occur of (i) such approval(s) contemplated by Paragraph A of Article VI of 
the Agreement and (ii) the financial institution regulatory approvals (but 
not the statutory waiting periods) contemplated by Paragraph B of Article 
VI of the Agreement (the "Exchange Ratio").  If such quotient is less than 
2.059, the Exchange Ratio shall be 2.059.  If such quotient is greater than 
2.506, the Exchange Ratio shall be 2.506.  All such shares of BankGroup 
Common Stock shall be validly issued, fully paid and nonassessable.

     The Exchange Ratio at the Effective Time of the Share Exchange shall 
be adjusted to reflect any consolidation, split-up, other subdivisions or 
combinations of BankGroup Common Stock, any dividend payable in 

                                 30
<PAGE>

BankGroup Common Stock, or any capital reorganization involving the 
reclassification of BankGroup Common Stock subsequent to the date of the 
Agreement.

     After the Effective Time of the Share Exchange, each holder of a 
certificate theretofore representing outstanding shares of Bank Common 
Stock, upon surrender of such certificate to Registrar and Transfer 
Company (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 BankGroup Common Stock for which shares of Bank Common 
Stock previously represented by the certificate or certificates so 
surrendered shall have been exchanged as provided plus cash in lieu of any 
fractional share.  Until so surrendered, each outstanding certificate which, 
prior to the Effective Time of the Share Exchange, represented Bank Common 
Stock will be deemed to evidence the right to receive the number of full 
shares of BankGroup Common Stock into which the shares of Bank Common Stock 
represented thereby may be converted, and, after the Effective Time of the 
Share Exchange, will be deemed for all corporate purposes of BankGroup 
to evidence ownership of the number of full shares of BankGroup Common 
Stock into which the shares of Bank Common Stock represented thereby 
were converted.  Until such outstanding certificates formerly representing 
Bank Common Stock are surrendered, no dividend payable to holders of 
record of BankGroup Common Stock for any period as of any date 
subsequent to the Effective Time of the Share Exchange shall be paid to the 
holder of such outstanding certificates in respect thereof.  After the 
Effective Time of the Share Exchange there shall be no further registry of 
transfer on the records of Bank of shares of Bank Common Stock.  If a 
certificate representing such shares is presented to the Exchange Agent, it 
shall be canceled and exchanged for a certificate representing shares of 
BankGroup Common Stock as herein provided.  BankGroup will also issue 
a certificate in exchange for shares evidenced by lost certificate(s) 
provided the record owner thereof provides BankGroup with such 
substantiation, indemnification and security as BankGroup may reasonably 
require.

     Upon surrender of certificates of Bank Common Stock in exchange for 
BankGroup Common Stock, there shall be paid to the recordholder of the 
certificates of BankGroup Common Stock issued in exchange thereof (i) the 
amount of dividends theretofore paid with respect to such full shares of 
BankGroup Common Stock as of any date subsequent to the Effective Time 
of the Share Exchange 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 Time of 
the Share Exchange, 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.
   
     Each Warrant subject to redemption in the Transaction shall, by
agreement between the holder and Bank, be redeemed at the Effective Time
of the Share Exchange and the holder shall be entitled to receive for each 
such Warrant that number of shares of BankGroup Common Stock equal to the 
quotient obtained by dividing $31.00 by the Average BankGroup Stock Price 
("Warrant Redemption Ratio").  If the Warrant Redemption Ratio computed 
in accordance with the immediately preceding sentence is less than 1.228, 
the Warrant Redemption Ratio shall be 1.228 ("Lower Collar"); if the Warrant
Redemption Ratio computed in accordance with the immediately preceding
sentence is greater than 1.494, the Warrant Redemption Ratio shall be 1.494
("Upper Collar"); provided, however, that if the Warrant Redemption Ratio
determined in accordance with the immediately preceding clause equals either
the Lower Collar or the Upper Collar, the Warrant Redemption Ratio shall be
further adjusted, if necessary, so that shares of MSBC Common Stock to be
issued for each CB Warrant pursuant thereto shall be equal in value to the
difference obtained by subtracting $21.00 from the product of the Average
MSBC Share Price times the Exchange Ratio (as defined in Article II, Paragraph
B).
    
   
     As of a date which is no later than 30 days before the Share Exchange
Closing, Bank shall deposit in escrow with an escrow agent mutually
satisfactory to it and BankGroup all outstanding shares of Bank Preferred
Stock and all Warrants to be redeemed under the terms of the Agreement
together with all other documents necessary to accomplish the redemption
thereof including the agreements of the holders thereof to redeem as of the
Share Exchange Closing all issued and outstanding shares of Bank Preferred
Stock and Warrants in return for the shares of BankGroup Common Stock to
which they are entitled under the terms of the Agreement.  As of the Share
Exchange Closing, the holders of Bank Preferred Stock and Warrants shall be
entitled to receive from BankGroup the shares of BankGroup Common Stock as
provided in the Agreement and their individual agreements shall have no
further rights under the terms of the Bank Preferred Stock and Bank Warrants, 
which shall be considered redeemed as of the Share Exchange Closing.

Business of Bank Pending the Transaction

     Bank has agreed that prior to the Effective Time of the Share Exchange, 
it will operate its business substantially as presently operated and in the 
ordinary course, and, consistent with such operation, will use its best 
efforts to preserve intact its present business organization and 
relationships with persons having business dealings with it.  The Agreement 
contains a description of certain specified actions to be taken or 
refrained from by Bank in satisfying this undertaking.

     Bank further has agreed that, prior to the Effective Time of the Share 
Exchange, it will consult and reasonably cooperate with BankGroup 
regarding (i) loan portfolio management, including management and work-
out of nonperforming assets, and credit review and approval procedures; (ii) 
securities portfolio and funds management, including management of 
interest rate risk; and (iii) expense management, all with the objective of 
achieving appropriate operating synergies and appropriate accruals prior to 
the Effective Time of the Share Exchange.

Conditions to Consummation of the Transaction

     Consummation of the Transaction is conditioned upon the approval of 
the Share Exchange by the holders of at least two-thirds of the outstanding 
Bank Common Stock entitled to vote at the Bank Shareholder Meeting.  
The Transaction must be approved by the Federal Reserve Board, the 
Bureau of Financial Institutions of the Virginia State Corporation 
Commission and the Maryland Commission of Financial Regulations, 
applications for which have been filed and approvals for which are expected 
to be received.  The Transaction is also conditioned on the holder of Bank 
Preferred Stock and the holders of all outstanding Warrants for Bank 
Common Stock and Bank Preferred Stock (with certain limited exceptions) 
agreeing at least thirty (30) days in advance of the closing of the Share 
Exchange to accept shares of BankGroup Common Stock in redemption of 
their Bank Preferred Stock (based on the Exchange Ratio also applicable to 
the Share Exchange) and in satisfaction of their Warrant rights (based on 
the Warrant Redemption Ratio).  Under certain circumstances, the Bank 
Board may notify BankGroup of an election to terminate the Transaction 
made during the ten (10) day period preceding the closing if the average 
bid/ask price for BankGroup Common Stock during the 20 trading day 
period preceding the tenth day prior to closing is less than $20.75 and if 
the percentage reduction in the price of BankGroup Common Stock obtained by 
subtracting the 20 trading day average price from $23.625 (the average of 
bid and ask price for BankGroup Common Stock on June 18, 1997) is at 
least 10 percentage points greater than the percentage reduction in the SNL 
Southeast Bank Index for the same period.  In this event BankGroup may 
either allow termination of the transaction or increase the consideration to 
be received by Bank shareholders and Warrant holders to a quotient, the 

                                 32
<PAGE>


numerator of which is $20.75 multiplied by the applicable Exchange or 
Warrant Redemption Ratio and the denominator of which is the 20 day 
trading day average price.  If BankGroup elects to do so, then the 
Transaction does not terminate or account of the Bank Board's earlier 
election.  The obligations of Bank and BankGroup to consummate the Share 
Exchange are further conditioned upon the satisfaction of terms and 
conditions contained in the Agreement usual for transactions of this type, 
including continued accuracy of representations and warranties made by 
Bank and BankGroup, the absence of material adverse change in Bank's and 
BankGroup's businesses, the receipt of legal and accounting opinions, and 
the Transaction being accounted for as a "pooling of interests."  See 
Article VI of the Agreement (Annex A).

Termination

     The Agreement will be terminated, and the Transaction abandoned, if 
shareholders of Bank do not approve the Share Exchange or if the holder 
of Bank Preferred Stock and the holders of Warrants (with certain limited 
exceptions) do not agree within 30 days of the closing to the redemption 
of their shares and Warrants as provided in the Agreement.  Notwithstanding 
such approval by such shareholders or agreements by Bank Preferred 
Stock and Warrant holders, the Agreement also may be terminated at any 
time prior to the Effective Time of the Share Exchange by mutual consent, 
upon breach of the Agreement, if the Share Exchange is not effective by 
December 31, 1997, and upon the occurrence of certain other events 
specified in the Agreement.  See Article VII of the Agreement (Annex A).

Accounting Treatment

     BankGroup and Bank have agreed to use their best efforts to cause the 
Transaction to be accounted for as a "pooling of interests" and this 
accounting treatment is a condition to BankGroup's obligation to complete 
the Transaction.

Operations After the Transaction

     After consummation of the Transaction, BankGroup will continue generally 
to conduct the business presently conducted by Bank.  

Interests of Certain Persons in the Transaction

     Certain members of the Bank Board and Bank's management may be deemed to 
have interests in the Transaction in addition to their interests as 
shareholders of Bank generally.  In each case, the Bank Board or Bank was 
aware of their potential interests, and considered them, among other 

                                33
<PAGE>


matters, in approving the Agreement and the transactions contemplated 
thereby.

Indemnification; Liability Insurance.  BankGroup agrees that for the six-
year period following the Share Exchange Effective Date, it shall cause 
Bank and any successor thereto to indemnify and hold harmless any person 
who has rights to indemnification from Bank to the same extent and on the 
same conditions as such person is entitled to indemnification pursuant to 
Bank's Articles of Incorporation as in effect on the date of the Agreement, 
to the extent legally permitted to do so, with respect to matters 
occurring on or prior to the Share Exchange Effective Date (regardless of 
whether a claim is asserted in connection therewith on or prior to the 
Share Exchange Effective Date or thereafter), as detailed in the Agreement.
BankGroup shall use its reasonable best efforts to provide coverage to the 
officers and directors of Bank under BankGroup's 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 BankGroup 
as further detailed in the Agreement.

     Additionally, the Bank shall have the power to indemnify its directors 
and officers against liability for acts or omissions before the Effective 
Time of the Share Exchange to the extent permitted under Maryland law, the 
Bank Articles of Incorporation and any applicable federal banking laws and 
regulations or regulatory actions pursuant thereto.    

Employee Benefits.  Upon consummation of the Share Exchange, as soon as 
administratively practicable employees of Bank shall be entitled to 
participate in BankGroup's pension, severance, benefit and similar plans on 
the same terms and conditions as employees of BankGroup and its 
subsidiaries.  BankGroup shall cause Bank to honor in accordance with their 
terms as in effect on the date hereof, or as amended after the date hereof 
with the prior written consent of BankGroup, all employment, severance, 
consulting and other compensation contracts and agreements and executed 
in writing by both Bank on the one hand and any individual current or 
former director, officer or employee thereof on the other hand. 

Redemption of Warrants.  BankGroup has agreed, subject to the agreement 
of the Warrant holders with Bank, to issue BankGroup Common Stock in 
redemption of all outstanding Warrants for Bank Common Stock based on the 
Warrant Redemption Ratio.  Members of the Bank Board, bank officers and
affiliates hold a total of 55,747 of such Warrants, or 64.4% of the total 
number of such Warrants outstanding. 

Bank Board of Directors.  The directors of the Bank are expected to 
continue to serve on the Bank's Board of Directors and Board Committees.  
Such directors of the Bank are expected to continue to receive fees for 
serving as members of the Board of Directors and its Committees.

                                 34
<PAGE>


     Other than as set forth above, no director or executive officer of Bank 
or BankGroup has any direct or indirect material interest in the Transaction, 
except in the case of directors and executive officers of Bank insofar as 
ownership of Bank Common might be deemed to be such an interest. 

Certain Federal Income Tax Consequences

     Set forth below is a discussion of certain federal income tax
consequences under the Internal Revenue Code of 1986, as amended (the 
"Code")to (i) Bank Common and Preferred shareholders who receive BankGroup 
Common Stock solely in exchange for Bank Common or Preferred Stock
as a result of the Transaction, (ii) Bank Warrant holders who
receive BankGroup Common Stock and cash in lieu of fractional shares
solely in exchange for Bank Common or Preferred Stock Warrants as a
result of the Transaction, and (iii) Bank shareholders who receive cash
in lieu of fractional shares or who receive cash for their shares upon
exercise of dissenters' rights.  The discussion does not deal with all
aspects of federal taxation that may be relevant to particular Bank
shareholders or Warrant holders.  In view of the individual nature of
tax consequences, Bank shareholders and Warrant holders are urged to
consult their own tax advisors as to the specific tax consequences
to them of the Transaction, including the applicability of federal,
state, local and foreign tax laws.

     Neither BankGroup nor Bank has requested a ruling from the Internal
Revenue Service ("IRS") in connection with the Transaction.  BankGroup
and Bank have received from Flippin, Densmore, Morse, Rutherford &
Jessee, counsel to BankGroup, an opinion as to certain of the
federal income tax consequences of the Transaction (the "Opinion").
The Opinion represents the best judgment of counsel as to the probable
outcome of the tax issues discussed.  It is not binding on the IRS or
any tax authority or court.  Further, in such Opinion, counsel
gives no assurances that the IRS will not challenge counsel's conclusions
and prevail in the courts in such a matter so as to cause adverse tax
consequences to BankGroup, Bank, and its shareholders and Warrant holders.

     In the opinion of counsel, for federal income tax purposes, the
proposed Share Exchange and the proposed exchange of BankGroup Common

                               35
<PAGE>

Stock for Bank Preferred stock will qualify as a reorganization under
368(a)(1)(B) of the Internal Revenue Code of 1986 (the "Code"), and,
consequently, no gain or loss will be recognized by Bank Common or
Preferred shareholders on the receipt of BankGroup Common Stock
solely in exchange for their Bank Common or Preferred Stock.  
HOWEVER, THE RECEIPT OF CASH BY A BANK SHAREHOLDER,
INCLUDING THE RECEIPT OF CASH BY A DISSENTING
SHAREHOLDER AND THE RECEIPT OF CASH IN LIEU OF A
FRACTIONAL SHARE OF BANKGROUP COMMON STOCK, WILL BE
A TAXABLE TRANSACTION AND THE EXCHANGE OF BANK COMMON
OR PREFERRED STOCK WARRANTS FOR BANKGROUP COMMON STOCK
AND CASH IN LIEU OF FRACTIONAL SHARES OF BANKGROUP
COMMON STOCK WILL BE A TAXABLE TRANSACTION.

     Specifically, the Opinion states that, among other things:

     1.    No gain or loss will be recognized by BankGroup on the
receipt of Bank Common Stock and Bank Preferred Stock solely in 
exchange for BankGroup Common Stock.

     2.     No gain or loss will be recognized by the Bank Common
Stock shareholders or the Bank Preferred Stock shareholders on the
receipt of BankGroup Common Stock solely in exchange for their
Bank Common or Preferred Stock.

     3.     The tax basis of the shares of BankGroup Common Stock to
be received by Bank shareholders in the Transaction in exchange for
their Bank Common or Preferred Stock will be the same as the basis
of the Bank Common or Preferred Stock surrendered in exchange
therefor.

     4.     The holding period under Section 1223 of the Code for the
shares of BankGroup Common Stock to be received by Bank shareholders
in the Transaction will include the holding period for the shares of
Bank Common or Preferred Stock surrendered in exchange therefor, provided
that the Bank Common or Preferred Stock shareholder held such stock as
a capital asset on the date of the Share Exchange.

     5.     The tax basis of the Bank Common and Preferred Stock to be
received by BankGroup in the Transaction will be the same as the basis
of such stock in the hands of Bank shareholders immediately prior to
the exchange.

     6.     The holding period under Section 1223 of the Code of the Bank
Common and Preferred Stock to be received by BankGroup in the Transaction
will include the period during which such Common or Preferred Stock
was held by the Bank shareholders.

     7.     Any dissenting shareholder of Bank Common Stock who receives
solely cash in exchange for shares of Bank Common Stock will be treated
as receiving a distribution in redemption of such stock subject to
the provisions and limitations of Section 302 of the Code.

                                36
<PAGE>

     8.     Any shareholder of Bank stock who receives cash in lieu of
a fractional share interest shall be treated as receiving a payment in
redemption of such fractional interest subject to the provisions and
limitations of Section 302 of the Code.  Gain or loss will be realized
and recognized to such shareholder measured by the difference between
the redemption price and the portion of the shareholders' basis in
Bank stock allocable to such fractional share interest.

     9.     The exchange of the Bank Common Stock Warrants and the
Bank Preferred Stock Warrants for BankGroup Common Stock will be
a taxable transaction.  Gain or loss will be recognized by Bank
Common Stock Warrant holders and Bank Preferred Stock Warrant
holders as a result of the exchange of such Warrants in return for
Common Stock of BankGroup and cash in lieu of fractional shares.

     The Opinion is based on the assumption that the Transaction as it
relates to Bank Preferred Stock and Warrants will be treated for
federal income tax purposes as an exchange of such Preferred Stock
and Warrants for solely BankGroup Common Stock as part of or pursuant
to a plan of reorganization.  The Opinion is also based on certain 
customary assumptions and representations regarding, among other things, 
the lack of previous dealings between Bank and BankGroup, the 
existing and future ownership of BankGroup Common Stock and Bank stock, 
whether Common or Preferred, and the future business plans for BankGroup.  
Receipt of substantially the same opinion of Flippin, Densmore, Morse, 
Rutherford & Jessee as of the Share Exchange Effective Date is a condition 
to consummation of the Transaction.

     The federal income tax consequences discussed above are necessarily
general as to the various shareholders and Warrant holders of the Bank,
and their applicability may vary depending upon the individual 
circumstances.  This summary is not intended to be a substitute for
careful tax planning on an individual basis.  It is recommended that
each Bank shareholder and Warrant holder consult his or her own tax advisor
to determine whether or not there are any tax consequences of the
Transaction that might be of particular concern due to a 
shareholder or Warrant holder's individual tax situation.

     THE BANK BOARD UNANIMOUSLY RECOMMENDS A VOTE FOR THE 
SHARE EXCHANGE.

Rights of Appraisal

   Under the applicable provisions of the Maryland General Corporation Law,
each holder of Bank stock will be entitled to demand and receive payment of
the fair value of his shares, if he (i) prior to or at the meeting, files with
the Bank a written objection to the Share Exchange, (ii) does not vote in favor
of the Share Exchange, and (iii) within 20 days after Articles of Share Exchange
have been accepted for record by the Maryland Department of Assessments and
Taxation (the "Department"), makes written demand on Bank for payment of his
shares, stating the number of shares for which payment is demanded.  A direction
in the stockholder's proxy to vote against the Share Exchange will not in itself
constitute a written objection or demand that satisfies the requirements
described above.  Any stockholder who fails to comply with the requirements
described above will be bound by the terms of the Share Exchange.

                               37
<PAGE>

     Bank will promptly deliver or mail to each objecting stockholder written
notice of the date of acceptance of the Articles of Share Exchange for record
by the Department.  Bank may also deliver or mail to each objecting stockholder
a written offer to pay for his stock at a price deemed by Bank to be the fair
value thereof.  Within 50 days after acceptance of the Articles of Share
Exchange for record by the Department, either Bank or any objecting stockholder
who has not received payment for his shares may petition the court in Prince
George's County, Maryland, for an appraisal to determine the fair value
of such shares.  If the court finds that an objecting stockholder is entitled
to appraisal of his stock, the court will appoint three disinterested appraisers
to determine the fair market value of such shares on terms and conditions the
court determines proper, and such appraisers will, within 60 days after
appointment (or such longer period as the) court may direct), file with the
court and mail to each party to the proceeding their report stating their
conclusion as to the fair value of such shares.  Within 15 days after the filing
of such report, any party may object to such report and request a hearing
thereon.  The court will, upon motion of any party, enter an order either
confirming, modifying or rejecting such report and, if confirmed or modified,
enter judgment directing the time within which payment will be made.  If the
appraisers' report is rejected, the court may determine the fair value of the
shares of the objecting stockholders or may remit the proceeding to the same or
other appraisers.  Any judgment entered pursuant to a court proceeding will
include interest from the date of the stockholder's vote on the action to which
objection was made.  Costs of the proceeding shall be determined by the court
and may be assessed against Bank or, under certain circumstances, the objecting
stockholder, or both.

     At any time after the filing of a petition for appraisal, the court may
require objecting stockholders to submit their certificates representing shares
to the clerk of the court for notation of the pendency of the appraisal
proceedings.  A stockholder demanding payment for shares will not have the right
to receive any dividends or distributions payable to holders of record after the
close of business on the date of the stockholders' vote and will cease to have
any rights as a stockholder with respect to such shares except the right to
receive payment of the fair value thereof.


                       MAINSTREET BANKGROUP INCORPORATED

General

     MainStreet BankGroup Incorporated is a multi-bank holding company 
headquartered in Martinsville, Virginia, with total assets of $1.4 billion 
at June 30, 1997.  Organized in 1977, BankGroup, through its eight affiliate 
banks (the "Banks"), and MainStreet Trust Company, National Association, a 
nationally chartered trust company ("Trust Company"), engages in a general 
banking business and provides 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 construction loans; issuing letters of 
credit; and providing discount brokerage, trust services, bank-card services,
mortgage banking and investment services.

                                 38
<PAGE>

     The Banks seek customers whose total financial requirements they can 
serve.  As a result, most of the Banks' business customers are small and 
medium-sized entities.  While BankGroup considers this middle market to be 
its primary business market, BankGroup's lead bank, Piedmont Trust Bank, 
has banking relationships with many of the larger textile and furniture 
manufacturing companies located in its market area.

     Principal markets served are the City of Martinsville and Henry County; 
the Town of Hillsville and City of Galax, and Carroll and Grayson Counties; 
the Towns of Ferrum and Rocky Mount and Franklin County; the Town of Forest,
City of Lynchburg, and Bedford, Campbell and Amherst Counties; the Town of 
Stuart and Patrick County; the Towns of Saltville and Chilhowie and Smyth 
County; the towns of Mechanicsville and Ashland, and Hanover and Henrico 
Counties; and the City of Clifton Forge and Allegheny, Bath and northern 
Botetourt Counties, Virginia and contiguous areas.  BankGroup's affiliate 
Banks operate a total of 35 offices.

     BankGroup continually seeks acquisition opportunities for banks and 
bank related financial institutions.  BankGroup's acquisition philosophy 
permits the Banks to operate as separately chartered banks with their 
historical names and board of directors.  BankGroup believes that this 
philosophy maintains community loyalty at the Banks and has a positive 
effect on operating performance.  BankGroup seeks to capitalize on the 
local identity of the Banks while providing the services and efficiencies 
of a larger bank holding company.

     During 1994, BankGroup moved to a centralized approach in management, 
providing direction to the Banks and performing selected services in the 
compliance, data processing, financial management, human resources, 
investment, accounting, marketing, mortgage, trust and audit areas.  
The Banks are still permitted to approve loans up to a certain credit 
limit, above which central credit administration must consent.  
The Banks also still must approve investments and other activities 
consistent with past practices and the needs of their communities.  
To coordinate the activities of the Banks and to maintain internal 
controls, BankGroup utilizes a planning and budgeting process which involves 
Company officers, presidents of the Banks, and principal department heads.  
Performance targets and budget goals are developed for each Bank on an 
annual basis, with financial and operating results reported and reviewed 
periodically during the year.

     During 1997, BankGroup organized MainStreet Trust Company to offer 
fiduciary services in all the markets served by its affiliate banks and 
elsewhere.  This centralized approach to fiduciary services allows BankGroup 
affiliates to offer to the customer a broader array of more sophisticated 
products more efficiently and effectively than could otherwise be 
accomplished.

Recent Development

     On July 25, 1997, BankGroup announced that it had reached agreement to 
acquire Tysons Financial Corporation ("Tysons"), a Virginia corporation, 
located in McLean, Virginia, subject to shareholder and regulatory approval.
Under the terms of the agreement, BankGroup agreed to pay shareholders of 
Tysons the equivalent of $14.50 per share for each share of Tysons Common 
Stock outstanding.  The transaction is valued at approximately $17.2 million,
which will be paid in BankGroup Common Stock.  The exchange ratio will be 
determined during a measurement period prior to consummation of the 
transaction, which is expected around January 1, 1998.  The transaction 
will be treated as a purchase.

     In addition, it is a condition of the merger that Tysons' outstanding 
228,250 directors' warrants be exercised prior to the closing for the 
difference between the exercise price per warrant and $14.50 in the form of 
Tysons' common stock.  BankGroup has also agreed to redeem Tysons' 
outstanding Directors' Options for the difference between the exercise 
price per Option and $14.50 in the form of BankGroup Common Stock. It is 
a condition to the merger that the holders of Tysons' outstanding Directors'
Options agree to accept this arrangement.  It is also a condition to closing
that every holder of an option granted to employees and officers of Tysons 
to purchase Tysons Common Stock ("ISO") shall agree to accept the conversion 
of such ISO with respect to BankGroup Common Stock as contemplated in the 
merger agreement between Tysons and BankGroup.  

     Tysons has one wholly owned banking subsidiary, Tysons National 
Bank ("TNB"), located in the county of Fairfax, Virginia.  TNB's main office
and three branches are located in Fairfax County, Virginia.  At June 30, 
1997, Tysons reported total assets of $86.2 million.

     The payment of future dividends will depend upon future earnings of 
BankGroup, its financial condition and other relevant factors, including 
the amount of dividends payable to BankGroup by the Banks.  Various federal 
and state laws, regulations and policies limit the ability of BankGroup's 
subsidiary banks to pay dividends to BankGroup, which affects BankGroup's 
ability to pay dividends to shareholders.  See "Regulation and Supervision."

                         COMMERCE BANK CORPORATION

General

     The Bank is a Maryland banking corporation that was organized and 
chartered under the laws of the State of Maryland on December 31, 1987 and 
commenced business on September 21, 1989.

     The Bank is a state member bank of the Federal Reserve System and is 
examined by that agency and the Maryland banking regulatory authorities.  
The Bank conducts its commercial banking business under a variety of federal 
and state laws and regulations, some of which relate to interest rates, 


                                 43
<PAGE>


required reserves, restrictions on loans to officers, the use of 
correspondent balances, the establishment of branches and the acquisition of
subsidiaries.  The Federal Reserve Board and the Maryland Division of 
Financial Regulations has statutory authority to issue "cease and desist" 
orders to the Bank with respect to actions deemed to constitute a serious 
threat to the safety, soundness and stability of the Bank.

     The Bank principally serves the small to mid-size business community, 
offering customary commercial demand and time deposit accounts and customary
forms of credit accommodations.  No material portion of the Bank's deposits 
has been obtained from a single or small group of customers and the loss of 
the deposits of any one customer or of a group of customers would not have 
an adverse material effect on the business of the Bank.  

     Bank operations are conducted in three locations in Prince George's 
County, Maryland.  On August 25, 1997, Commerce Bank had 21 full-time and 5
part-time employees.  

Competition

     The Bank's primary service area is Prince George's County, Maryland.  
The Board of Directors believes that the existing and future market in this 
service area presents a beneficial opportunity for a locally operated bank.  

     The banking business in Maryland, as elsewhere, is highly competitive.  
Other Maryland banking institutions with substantially greater financial 
resources than the Bank are aggressively competing in the Bank's service 
area for loans, deposit and other banking services.  At June 30, 1996, there
were 20 commercial banks with 142 branch offices in the Bank's primary 
service area in Prince George's County.  Of the total number of commercial 
banks noted, there are 2 other independent community banks operating within
Prince George's County.

Regulation and Supervision

     The operations of Commerce Bank are subject to federal and state 
statutes which apply to state member banks of the Federal Reserve System.  
The Bank, as a state member bank, is supervised and regularly examined by 
the Department of Bank Supervision and Regulation of the Federal Reserve 
Bank.  At the state level, the Bank is subject to supervision and 
examination by the Maryland Division of Financial Regulations.

Properties

     The Bank leases quarters that are used in the normal course of business 
at locations in Lanham and Hyattsville, Maryland.  The Bank's principal or 
main office is located within leased property at  9658 Baltimore Avenue, 
College Park, Maryland, 20740.

                      REGULATION AND SUPERVISION

     Bank holding companies and banks operate in a highly regulated 
environment and are regularly examined by federal and state regulators.  
The following description briefly discusses certain provisions of federal 
and state laws and certain regulations and the potential impact of such 
provisions on BankGroup and the Banks.  These federal and state laws and 
regulations have been enacted for the protection of depositors in national 
and state banks and not for the protection of shareholders of bank holding 
companies such as BankGroup.  References to "Banks" means the current 
subsidiary banks of BankGroup.

Bank Holding Companies

     As a bank holding company registered under the Bank Holding Company Act 
of 1956, as amended (the "BHCA"), BankGroup is subject to regulation by the
Federal Reserve Board.  The Federal Reserve Board has jurisdiction under the
BHCA to approve any bank or nonbank acquisition, merger or consolidation 
proposed by a bank holding company.   The Federal Reserve Board has recently 
adopted regulations allowing (under certain circumstances) an expedited 
approval process for these transactions for well managed and well 
capitalized bank holding companies.  The BHCA generally limits the 
activities of a bank holding company and its subsidiaries to that of 
banking, managing or controlling banks, or any other activity which is so 
closely related to banking or to managing or controlling banks as to be a 
proper incident thereto.  This limits their ability to engage in financial 
services such as insurance or securities underwriting as well as non- 
financial activities.  In recent years, however, the Federal Reserve Board 
has expanded the range of permissible securities activities of bank holding 
companies and their subsidiaries. 

     The BHCA also prohibits a bank holding company, with certain exceptions,
from acquiring more than 5% of the voting shares of any company that is not a
bank and from engaging in any business other than banking or managing or 
controlling banks.  Under the BHCA, the Federal Reserve Board is authorized 
to approve the ownership of shares by a bank holding company in any company 
the activities of which the Federal Reserve Board has determined to be so 
closely related to banking or to managing or controlling banks as to be a 
proper incident thereto.  The Federal Reserve Board has by regulation 
determined that certain activities are closely related to banking within 
the meaning of the BHCA. These activities include: operating a mortgage 
company, finance company, credit card company or factoring company; 
performing certain data processing operations; providing investment and 
financial advice; and acting as an insurance agent for certain types of 
credit-related insurance.  Well capitalized and well managed bank holding 

                                 47
<PAGE>

companies may engage in any activity (subject to certain limitations) that 
the Federal Reserve Board has determined by order to be closely related to 
banking without prior notice to or approval of the Federal Reserve Board.

     Federal law permits bank holding companies from any state to acquire 
banks and bank holding companies located in any other state.  Effective 
June 1, 1997, the law allowed interstate bank mergers, subject to earlier 
"opt-in" or "opt-out" action by individual states.  The law currently 
allows interstate branch acquisitions and de novo branching if permitted by 
the host state.  Virginia adopted early "opt-in" legislation that 
allowed interstate bank mergers.  These laws also permit interstate branch 
acquisitions and de novo branching in Virginia by out-of-state banks if 
reciprocal treatment is accorded Virginia banks in the state of the 
acquirer.  Maryland law permits the acquisition of a Maryland bank or a 
Maryland bank holding company by out of state banks or bank holding 
companies upon the approval by the Maryland Bank Commissioner and as
permitted by federal law.  

     There are a number of obligations and restrictions imposed on bank 
holding companies and their depository institution subsidiaries by federal 
law and regulatory policy that are designed to reduce potential loss 
exposure to the depositors of such depository institutions and to the FDIC 
insurance fund in the event the depository institution becomes in danger of 
default or in default.  For example, under a policy of the Federal Reserve 
Board with respect to bank holding company operations, a bank holding 
company is required to serve as a source of financial strength to its 
subsidiary depository institutions and to commit resources to support such 
institutions in circumstances where it might not do so otherwise.  In 
addition, the "cross-guarantee" provisions of federal law require insured 
depository institutions under common control to reimburse the FDIC for
any loss suffered or reasonably anticipated by either as a result of the 
default of a commonly controlled insured depository institution or for any 
assistance provided by the FDIC to a commonly controlled insured depository 
institution in danger of default.  The FDIC may decline to enforce the 
cross- guarantee provisions if it determines that a waiver is in the best 
interest of the SAIF or the BIF or both.  The FDIC's claim for reimbursement
is superior to claims of shareholders of the insured depository institution 
or its holding company but is subordinate to claims of depositors, secured 
creditors and holders of subordinated debt (other than affiliates) of the 
commonly controlled insured depository institution.  

     The Federal Deposit Insurance Act ("FDIA") also provides that amounts 
received from the liquidation or other resolution of any insured depository 
institution by any receiver must be distributed (after payment of secured 
claims) to pay the deposit liabilities of the institution prior to payment 
of any other general or unsecured senior liability, subordinated liability, 
general creditor or shareholder.  This provision would give depositors a 

                               48
<PAGE>

preference over general and subordinated creditors and shareholders in the
event a receiver is appointed to distribute the assets of any of the Banks.


     BankGroup is registered under the bank holding company laws of Virginia. 
Accordingly, BankGroup and the Banks are subject to further regulation and 
supervision by the State Corporation Commission ("SCC").

Capital Requirements

     The Federal Reserve Board and the FDIC have issued substantially similar 
risk-based and leverage capital guidelines applicable to United States 
banking organizations.  In addition, those regulatory agencies may from 
time to time require that a banking organization maintain capital above 
the minimum levels because of its financial condition or actual or 
anticipated growth.  Under the risk-based capital requirements of these
federal bank regulatory agencies, BankGroup and the Banks are required to
maintain a minimum ratio of total capital to risk- weighted assets of at 
least 8%.  At least half of the total capital is required to be "Tier 1 
capital", which consists principally of common and certain qualifying 
preferred shareholders' equity, less certain intangibles and other 
adjustments.  The remainder "Tier 2 capital" consists of a limited amount 
of subordinated and other qualifying debt (including certain hybrid capital 
instruments) and a limited amount of the general loan loss allowance.  The 
Tier 1 and total capital to risk-weighted asset ratios of BankGroup as of 
June 30, 1997 were 13.64% and 14.89%, respectively, exceeding the 
minimums required.  The risk based capital guidelines have been amended 
over the years and are likely to be further amended and refined.  For 
example, the guidelines were amended in 1995 and 1996 to incorporate 
country transfer risk (that is, the possibility that an asset cannot be 
serviced in the currency of payment because of restraints on or lack of 
needed foreign currency in the country of the obligor) and market risk 
(applicable to exposure in investments) Banks subject to regulatory market 
risk requirements that are mandatory as of January 1, 1998 also will have 
a Tier 3 capital component.  Tier 3 capital consists of certain 
subordinated debt.  

     In addition, each of the federal regulatory agencies has established a 
minimum leverage capital ratio (Tier 1 capital to average tangible assets). 
These guidelines provide for a minimum ratio of 3% for banks and bank 
holding companies that meet certain specified criteria, including that they 
have the highest regulatory examination rating and are not contemplating 
significant growth or expansion.  All other institutions are expected 
to maintain a leverage ratio of at least 100 to 200 basis points above the 
minimum.  The Tier 1 capital leverage ratio of BankGroup as of June 30, 
1997, was 7.98%.  The guidelines also provide that banking organizations 
experiencing internal growth or making acquisitions will be expected to 
maintain strong capital positions substantially above the minimum 
supervisory levels, without significant reliance on intangible assets.

     The Federal Deposit Insurance Corporation Improvement Act of 1991 
("FDICIA") requires each federal banking agency to revise its risk-based 
capital standards to ensure that those standards take adequate account of 
interest rate risk, concentration of credit risk and the risks of 
nontraditional activities, as well as reflect the actual performance and
expected risk of loss on multi-family mortgages.  Rules have been 
promulgated with respect to concentration of credit risk and the risks of 
non-traditional activities, and also as to the risk of loss on multi-family 
mortgages.  In August 1995, the federal bank regulatory agencies revised 
their risk-based capital standards to provide explicitly for consideration
of interest rate risk in the overall determination of a bank's minimum 
capital requirement.  BankGroup does not expect any of these rules and 
revisions in the capital adequacy, either individually or in the aggregate, 
to have a material impact on its capital requirements.  However, the risk 
based capital guidelines, as they may be further developed and changed, 
could adversely affect an institution's capital portion and subject it to 
more stringent regulatory requirements.  

Limits on Dividends and Other Payments

     BankGroup is a legal entity separate and distinct from its subsidiary 
institutions.  Most of BankGroup's revenues come from dividends paid by the 
Banks.  Each of the Banks (with the exception of Clifton Forge) is a state 
member bank of the Federal Reserve System.  As a result, the Banks (with 
the exception of Clifton Forge) are regulated by the Federal Reserve Board 
and the SCC.  Clifton Forge and Trust Company are national banking 
associations and are regulated by the Office of the Comptroller of the 
Currency, and in addition, Clifton Forge is a member bank of the Federal 
Reserve System and regulated by the Federal Reserve Board.  There are 
various regulatory limitations applicable to the payment of dividends by 
the Banks and Trust Company as well as the payment of dividends by BankGroup
to its shareholders.  Under laws of Virginia applicable to the Banks (with 
the exception of Clifton Forge), prior approval from the bank regulatory 
agencies is required if cash dividends declared in any given year exceed
net income for that year plus net income for the prior two years less all 
dividends paid during the current year and two prior years.  National 
banking associations like Clifton Forge and Trust Company are permitted 
to pay dividends out of undivided profits but until their surplus equals 
their capital, dividends are generally prohibited unless at least a tenth 
of their net income for the preceding half year (if the dividend is a 
quarterly or semiannual dividend) or for the preceding two consecutive 
half year periods (if the dividend is an annual dividend) have been 
carried into a surplus.  In the case of Clifton Forge, Trust Company and 
BankGroup, the payment of dividends may also be limited by other factors,
such as requirements to maintain capital above regulatory guidelines.  
Under existing supervisory practices at June 30, 1997 the Banks could 
have paid additional dividends of $21.3 million without obtaining prior 
regulatory approval.  The Trust Company began its operations in 1997 and 

                               50
<PAGE>

is not in a position to pay a dividend without prior regulatory 
approval.  Bank regulatory agencies have authority to prohibit any Bank 
and Trust Company or BankGroup from engaging in an unsafe or unsound 
practice in conducting their business.  The payment of dividends, depending 
upon the financial condition of the Bank in question, Trust Company or 
BankGroup, could be deemed to constitute such an unsafe or unsound 
practice.  The Federal Reserve Board has stated that, as a matter of
prudent banking, a bank or bank holding company should not maintain its 
existing rate of cash dividends on common stock unless (1) the 
organization's net income available to common shareholders over the past 
year has been sufficient to fund fully the dividends and (2) the prospective 
rate of earnings retention appears consistent with the organization's 
capital needs, asset quality, and overall financial condition.

     Under the FDIA, insured depository institutions such as the Banks are 
prohibited from making capital distributions, including the payment of 
dividends, if, after making such distribution, the institution would 
become "undercapitalized" (as such term is used in the statute).  Based on 
the Banks current financial condition, BankGroup does not expect 
that this provision will have any impact on its ability to obtain dividends 
from the Banks.

     In addition to limitations on dividends, the Banks are limited in the 
amount of loans and other extensions of credit that may be extended to 
BankGroup, and any such loans or extensions of credit are subject to 
collateral security requirements.  Generally, up to 10% of each Bank's 
regulatory capital, surplus, undivided profits, allowance for loan losses 
and contingency reserves may be loaned to BankGroup.  There are other 
restrictions applicable to the transactions between the Banks and 
BankGroup.  As of June 30, 1997, approximately $9.5 million of credit was 
available to BankGroup under this limitation.

Subsidiaries

     The Banks are supervised and regularly examined by the Federal Reserve 
Board and the SCC except that Clifton Forge is regulated by the Federal 
Reserve Board and the OCC because it is a national banking association.  
Trust Company is regulated by the OCC because it is chartered as a national 
banking association, although its business is limited to the operation of a 
trust company.  The Banks and Trust Company are also subject to various 
requirements and restrictions under federal and (which has significantly 
more limited application to Clifton Forge and Trust Company as national 
banking associations) state law such as limitations on the types of 
services that they may offer, the nature of investments that they make, and 
the amounts of loans that may be granted.  Various consumer and compliance 
laws and regulations also affect the operations of the Banks.  Federal and 
state fiduciary laws and regulations affect the operations of Trust Company.
In addition to the impact of regulation, the Banks are affected 

                                51
<PAGE>


significantly by actions of the Federal Reserve Board in attempting to 
ontrol the money supply and the availability of credit.

     The Banks also are subject to the requirements of the Community 
Reinvestment Act (the "CRA").  The CRA imposes on financial institutions an 
affirmative and ongoing obligation to meet the credit needs of their local 
communities, including low- and moderate-income neighborhoods, consistent 
with the safe and sound operation of those institutions.  Until July 1, 
1997, each financial institution's efforts in meeting community credit needs
currently were evaluated as part of the examination process pursuant to 
twelve assessment factors.  As a result of a 1993 Presidential initiative, 
each of the federal banking agencies recently approved a final rule 
establishing a new framework for the implementation of CRA.  The new 
rule, which became fully effective on July 1, 1997, emphasizes an 
institution's performance in meeting community credit needs.  Institutions
are evaluated on the basis of a three pronged lending, investment and 
service test, with lending being of primary importance.  CRA ratings will 
continue to be a matter of public record, and CRA performance will continue 
to be evaluated in connection with mergers, acquisitions and branch 
applications.  Although the new rule is likely to have some impact on 
BankGroup's business practices, it is not anticipated that any changes 
will be material.  The Banks have attained either an "outstanding" or 
"satisfactory" rating on their most recent CRA performance evaluations.  

Deposit Insurance

     As institutions with deposits insured by BIF, the Banks also are 
subject to insurance assessments imposed by the FDIC.  Currently, a 
risk-based assessment schedule imposes assessments on BIF deposits, 
ranging from -0- for well-capitalized institutions to .27% of deposits for 
under-capitalized institutions.  All banks in BankGroup currently are 
assessed as well-capitalized.  

     As a result of the Deposit Insurance Funds Act of 1996, a separate levy 
is assessed on all BIF- and SAIF-assessable deposits to bear the cost of 
bonds sold by the Financing Corporation (FICO) for 1987-1989 in support of 
the former Federal Savings and Loan Insurance Corporation.  The 1996 law 
makes the FDIC the collection agent for FICO.  The FICO rates, subject to 
quarterly adjustment, are not tied to the FDIC risk classification. For 1997,
the FICO rate has ranged from 0.13% to .0126% of deposits.  

Other Safety and Soundness Regulations

     The federal banking agencies have broad powers under current federal law 
to take prompt corrective action to resolve problems of insured depository
institutions.  The extent of these powers depends upon whether the 
institutions in question are "well capitalized," "adequately capitalized," 

                                52

<PAGE>


"undercapitalized," "significantly undercapitalized" or "critically 
undercapitalized," as such terms are defined under uniform regulations 
defining such capital levels issued by each of the federal banking agencies.  

DESCRIPTION OF CAPITAL STOCK OF BANKGROUP

     BankGroup has authority to issue 1,000,000 shares of Preferred Stock, of 
which no shares are issued and outstanding, and 20,000,000 shares of Common
Stock, of which 11,396,976 shares were issued and outstanding as of July 31, 
1997 held by approximately 3,537 holders of record.  BankGroup Common Stock 
is traded in the over-the-counter market and quoted on The Nasdaq National 
Market under the symbol "MSBC".

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

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.  
Holders of the Preferred Stock, if and when issued, will be entitled to vote
as required under applicable Virginia law.  Such law includes provisions for 
the voting of the Preferred Stock in the case of any amendment to the 
Articles of Incorporation affecting the rights of holders of Preferred 
Stock, the payment of certain stock dividends, merger or consolidation, 
sale of all or substantially all of BankGroup's assets, and dissolution.  
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 shareholders.  In addition, the Preferred Stock 
could be used in a manner which would discourage or make more difficult an 
attempt to acquire control of BankGroup.  BankGroup's Board of Directors has 
designated a series of 1,000,000 shares of Participating Convertible 
Preferred Stock, Series A (the "Series A Preferred Stock"), no shares of 
which have been issued.  The Series A Preferred Stock was created in 
connection with the shareholder rights plan described below.

Common Stock

     Holders of 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 Common Stock.  Dividends may be paid to the holders 

                                  53
<PAGE>

of 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 Banks.  Payment of 
dividends to BankGroup by the Banks and Trust Company, without prior 
regulatory approval, is also subject to various state and federal regulatory 
limitations.  Holders of Common Stock have no conversion, redemption, 
cumulative voting or preemptive rights.  There is no sinking fund obligation 
with respect to the Common Stock.  In the event of any liquidation, 
dissolution or winding up of BankGroup, after payment or provision for 
payment of the debts and other liabilities and the preferential amounts to 
which the holders of Preferred Stock, if any, are entitled, the holders of 
Common Stock will be entitled to share ratably in any remaining assets.  

     All outstanding shares of Common Stock are, and the shares of Common 
Stock to be issued in the Share Exchange will be, when issued, duly and 
validly issued, fully paid and nonassessable.

Rights

     Pursuant to a Rights Agreement (the "Rights Agreement") dated as of 
January 18, 1990, BankGroup distributed as a dividend one Right for each 
outstanding share of Common Stock.  The number of Rights associated with 
each share of Common Stock outstanding as of June 30, 1993 was adjusted 
proportionately for the five-for-four stock split effected in the form of 
a dividend paid July 30, 1993 and the two-for-one stock split effected in 
the form of a stock dividend paid March 15, 1996.  Each Right entitles the 
holder to buy fractional shares of Participating Cumulative Preferred Stock, 
Series A, par value $5 per share, at an exercise price of $24, subject to 
adjustment.  The Rights will become exercisable only if a person or group 
acquires or announces a tender offer for 15% or more of the outstanding 
Common Stock.  When exercisable, BankGroup may issue a share of Common 
Stock in exchange for each Right other than those held by such person 
or group.  If a person or group acquires 30% or more of the outstanding 
Common Stock, each 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 BankGroup, Common Stock, having a value equal to twice the 
Right's exercise price.  If BankGroup is acquired in a merger or other 
business combination or if 50% of its earnings power is sold, each 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 exercise price of the Right.  The Rights will expire on January 18, 
2000, and may be redeemed by BankGroup 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 Common Stock, (i) the Rights will be evidenced 

                                 54
<PAGE>

by the Common Stock certificates and will be transferred with and only with 
such Common Stock certificates, and (ii) the surrender for transfer of any 
certificate for Common Stock will also constitute the transfer of the 
Rights associated with the Common Stock represented by such certificate.  
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 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 Right that is the subject of a purported transfer to any 
such person will be null and void.  

     The 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 Rights will cause substantial 
dilution to any person or group that acquires more than 15% of the 
outstanding shares of Common Stock of BankGroup if certain events 
thereafter occur without the Rights having been redeemed.  For example, if 
thereafter such acquiring person acquires 30% of BankGroup's outstanding 
Common Stock, or effects a business combination with BankGroup, the Rights 
permit shareholders to acquire securities having a value equal to twice 
the amount of the purchase price specified in the Rights, but rights held 
by such "acquiring person "are void to the extent permitted by law and may 
not be exercised.  Further, other shareholders may not transfer rights to 
such "acquiring person" above his or her 15% ownership threshold.  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 Rights could have the effect of discouraging acquisition 
transactions not approved by the Board of Directors.  The Rights do not 
interfere with any merger or other business combination approved by 
the Board of Directors and shareholders because the rights are redeemable 
with the concurrence of a majority of the "Continuing Directors," defined as 
directors in office when the Rights Agreement was adopted or any person 
added thereafter to the Board with the approval of the Continuing 
Directors.

Virginia Stock Corporation Act

     The Virginia Stock Corporation Act ("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 
Shareholder") by the holders of at least two-thirds of the remaining voting 
shares.  Affiliated Transactions subject to this approval requirement 
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 Shareholder, 
or any reclassification, including reverse stock splits, recapitalization or


                                55
<PAGE>
 
merger of the corporation with its subsidiaries which increases the 
percentage of voting shares owned beneficially by an Interested Shareholder 
by more than 5%.  For three years following the time that an Interested 
Shareholder becomes an owner of more than 10% of the outstanding voting 
shares, a Virginia corporation cannot engage in an Affiliated Transaction 
with such Interested Shareholder without approval of two-thirds of the 
voting shares other than those shares beneficially owned by the Interested 
Shareholder, and majority approval of the "Disinterested Directors." A 
Disinterested Director means, with respect to a particular Interested 
Shareholder, a member of BankGroup's Board of Directors who was (1) a 
member on the date on which an Interested Shareholder became an Interested 
Shareholder and (2) 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 Shareholder.  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 Shareholder 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 Shareholder whose acquisition of shares 
making such person an Interested Shareholder 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 
Shareholder, 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.  BankGroup 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 
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 or any 
officer or employee-director of the Virginia corporation.  This 

                                56
<PAGE>

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.  

Reports to Shareholders

     BankGroup furnishes shareholders with written annual reports containing 
consolidated financial statements audited by an independent certified public 
accountant and with written quarterly reports containing an unaudited balance
sheet at the end of each of the first three quarterly periods and an income 
statement for the period from the beginning of the current fiscal year to 
the end of such quarterly period.

Transfer Agent

     Registrar and Transfer Company, Post Office Box 1010, Cranford, New 
Jersey, is transfer agent for BankGroup Common Stock.  

                     COMPARATIVE RIGHTS OF SHAREHOLDERS

     At the Effective Time of the Share Exchange, shareholders of Bank will 
become shareholders of BankGroup, and holders of Bank Preferred Stock and 
Warrants (if they agree to do so) will lose their rights as such and will 
become entitled to receive the number of shares of BankGroup Common Stock 
based on the Exchange Ratio (in the case of Bank Preferred Stock) or the 
Warrant Redemption Ratio (in the case of Warrants).  As shareholders of 
BankGroup, their rights as shareholders will be determined by BankGroup's 
Articles of Incorporation and Bylaws and the VSCA.  The following is a 
summary of the material differences in the rights of shareholders of 
BankGroup and Bank.  This summary does not purport to be a complete 
discussion of, and is qualified in its entirety by reference to, the 
governing law and the Articles of Incorporation and Bylaws 
of each entity.

Capitalization

Bank.  Bank's Articles of Incorporation authorize the issuance of up to 
450,000 shares of common stock, par value $10 per share, 192,216 of which 
are issued and outstanding, and 50,000 shares of authorized convertible 
preferred stock, 30,984 shares of which are issued and outstanding.  

     BankGroup.  BankGroup's authorized capital is described under 
"Description of BankGroup Capital Stock."

                                 57
<PAGE>

Amendment of Articles or Bylaws

     Bank.  The Maryland General Corporate Law ("MDGCL") generally 
permits a Maryland corporation to adopt, alter and repeal its bylaws in a 
manner not inconsistent with the Maryland law or the corporation's charter.  
This authority to amend the bylaws is vested in the stockholders except to 
the extent that the charter vests it in the Board.  

     Bank's Bylaws may be amended by the Board of Directors or by the 
majority vote of the shareholders.  

     BankGroup.  As permitted by the VSCA, BankGroup's Articles provide 
that, unless a greater vote is required by law, by BankGroup's Articles or 
by a resolution of the Board of Directors, BankGroup's Articles may be 
amended if the amendment is adopted by the Board of Directors and approved 
by a vote of the holders of a majority of the votes entitled to be cast on 
the amendment by each voting group entitled to vote thereon.

     BankGroup's Bylaws generally provide that the Board of Directors may, by 
a majority vote, amend its Bylaws.  

Required Shareholder Vote for Certain Actions

     Bank.  The MDGCL generally requires the approval of a majority of a 
corporation's Board of Directors and the holders of at least two-thirds of 
all the votes entitled to be cast thereon by each group entitled to vote on 
any plan or merger of consolidation, plan of share exchange or sale of all 
or substantially all of the assets of a corporation outside the ordinary 
course of business.  

     The MDGCL also specifies additional voting requirements for "Business 
Combination" transactions and transactions which would cause certain 
acquiring persons voting power to meet or exceed specified thresholds.  
Generally speaking, a "Business Combination" is defined under MDGCL as an 
acquisition which involves a merger or share exchange with an acquiror 
which already owns or controls 10% or more of the voting stock of the 
target company.  In the event of a "Business Combination," a special 
acquisition shareholder voting requirement of 80% applies.  However, even 
in a situation in which the MDGCL Business Combination statute would apply, 
the Board of Directors of the target company is permitted to waive the 
extraordinary 80% voting requirement in favor of the usual two-thirds 
voting requirement.  Such a waiver must be made by the target Board of 
Directors prior to entering into a transaction which would cause the 
acquiror to become an interested party by acquiring a 10% or more interest 
in the target company.  The Stock Option Agreement between Bank and 
BankGroup entered into June 24, 1997, granted BankGroup the option to 
purchase 19.9% of Bank under certain limited circumstances.  As a result, 

                                 58
<PAGE>

the MDGCL Business Combinations statute would have applied to the Share 
Exchange.  However, prior to the execution of the Stock Option 
Agreement, Bank's Board of Directors passed a resolution waiving the 
extraordinary 80% voting requirement.  

     BankGroup.  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 any plan of merger or consolidation, plan of share exchange or sale 
of substantially all of the assets of a corporation not in the ordinary 
course of business.  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 under "Description of BankGroup Capital Stock -- Virginia Stock 
Corporation Act."

     None of the additional voting requirements contained in the VSCA are 
applicable to the Share Exchange since it is not an "Affiliated Transaction."  

Director Nominations

     Bank.  Bank's Bylaws provide that any nomination for election to the 
Board of Directors may be made by the Board of Directors or by any 
stockholder of any class of outstanding capital stock of the Bank entitled 
to vote for the election of directors.  Nominations other than the slate of 
nominees proposed by the Board of Directors, or a nomination by a director 
at a special meeting called to replace a director, must be made in 
writing and must be delivered to the President of the Bank not less than 60 
days nor more than 120 days prior to an annual meeting of the stockholders.  
The nomination must be on a form approved by the Bank and must specify 
certain information about the nominee such as name, address, stock holding, 
occupation and must also contain the nominee's signature evidencing his or 
her willingness to serve if elected.  Written nominations must also be 
seconded by another shareholder who is not related to the nominee.  No 
other nominations for the Board of Director are permitted.  The Board of 
Directors may disqualify the nomination of an individual whom counsel for 
the Bank may determine would not be legally qualified to serve as a director 
and certain procedures are outlined in the Bylaws for such disqualification 
and the filling of a board seat so vacated.  

     The Financial Institutions Article of the Annotated Code of Maryland 
("MDFI") requires that after the initial issuance of capital stock by a 
commercial bank, each of its directors shall own in good faith and of 
record unencumbered shares of the capital stock of: (i) the commercial bank, 
or (ii) a corporation that owns more than 80 percent of the capital stock 
of the commercial bank.  The unencumbered capital stock owned by the 


                                59
<PAGE>

director shall be in the amount of at least: (i) $500; or (ii) $250, if the 
commercial bank if a State bank that has $50,000 or less in capital stock.

     A majority of directors of Bank must be residents of Maryland.  In 
addition, MDFI requires that each director of Bank shall attend at least one 
half of the regularly scheduled board meetings that are held during the 
director's term of office.  Any directors who fails to attend meetings of 
the board of directors as required by MDFI is disqualified automatically 
from serving as director for a succeeding term.  The Maryland Bank 
Commission may waive the disqualification of a director if the director 
shows to the Commissioner good cause for the failure to attend the meetings.

     BankGroup.  BankGroup's Bylaws provide that any nomination for director 
made by a shareholder must be made in writing to the Secretary of BankGroup
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 BankGroup 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 BankGroup if so elected.  

     There is no requirement that directors of BankGroup own any capital 
stock of BankGroup.  There are also no residency or meeting attendance 
requirements applicable to directors of BankGroup.  

     Directors and Classes of Directors; Vacancies and Removal of Directors

     Bank.  The initial number of Directors of the Bank was set at 5.  
Thereafter, the number of Directors is set annually by a resolution of the 
Board of Directors adopted by a majority vote of the stockholders at a 
number not less than 5 nor more than 30.  The size of the current Board of 
Directors is 12.  There are no classes of Directors.  MDFI requires 
that all Directors serve for a stated term of not more than one year.  Any 
vacancy occurring on the Board of Directors, including a vacancy resulting 
from and increase in the number of Directors and any vacancy approved by 
the stockholders (not to exceed 2 board seats), may be filled by the 
affirmative vote of the majority of the remaining directors, though less 
than a quorum of the Board of Directors.  Directors so chosen hold 
office for a term expiring at the next following annual meeting of 

                                60
<PAGE>


shareholders at which directors are elected.  No decrease in the number of 
directors constituting the Board of Directors shall shorten the term of any 
incumbent director.  

     Any Director or the entire Board of Directors may be removed, with or 
without cause, by the holders of a majority of the shares then entitled to 
vote at an election of directors. 

     BankGroup.  The number of Directors is set forth in BankGroup's Bylaws.
The Board currently has fixed the number of directors at 11.  Any vacancy 
occurring on the Board of Directors, 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 
Board of Directors.  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 Board of Directors shall shorten the term of any incumbent director.  
Subject to the rights of the holders of 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.  

Anti-Takeover Provisions

     Bank.  The MDGCL specifies additional voting requirements for "Business 
Combination" transactions which would cause certain acquiring persons 
voting power to meet or exceed specified thresholds.  See "Required 
Shareholder Vote for Certain Actions" which describes these additional 
voting requirements applicable to Bank.  

     BankGroup.  For a description of certain provisions of VSCA which may 
be deemed to have an anti-takeover effect, see "Description of BankGroup 
Capital Stock -- Virginia Stock Corporation Act."

Preemptive Rights

     Shareholders of BankGroup do not have preemptive rights.  Thus, if 
additional shares of BankGroup common stock, or BankGroup preferred stock 
are issued, holders of such stock, to the extent they do not participate in 
such additional issuance of shares, would  own proportionately smaller 
interests in a larger amount of outstanding capital stock.

     Shareholders of Bank have preemptive rights.  Unless the charter 
provides otherwise, a stockholder does not have any preemptive rights as to 
a Maryland commercial bank with respect to: (i) stock issued to obtain any 
of the capital required to initiate the enterprise of the State bank or 
trust company; (ii) stock issued for at least its fair value in exchange for

                                 61
<PAGE>

consideration other than money; (iii) stock remaining unsubscribed for after
being offered to stockholders; (iv) treasury stock sold for at least its 
fair value; (v) stock issued or issuable under an agreement of merger; 
(vi) stock which is not presently entitled to be voted in the election of 
directors issued for at least its fair value; (vii) stock, including 
treasury stock, issued to an officer or other employee of the State bank 
or trust company or its subsidiary on terms and conditions approved by the 
stockholders by the affirmative vote of two-thirds of all the votes 
entitled to be cast on the matter; and (viii) any other issuance of shares 
if the applicability of preemptive rights is impracticable.  In 
the absence of actual fraud or gross disparity in the determination, the fair 
value of stock determined by the board of directors and recorded in the 
resolution authorizing the issuance is conclusive.  Unless the articles of 
incorporation provide otherwise, holders of the following securities do not 
have any preemptive tights under MDFI: (i) bonds, notes, debentures, or 
other obligations convertible into stock; and (ii) stock not presently 
entitled to be voted in the election of directors.  

     The Bank has elected in its Articles of Incorporation to provide 
preemptive rights to both holders of common stock and preferred stock.  
The terms of preemptive rights are essentially as follows except for the 
conversion of preferred stock, or the exercise of warrants or stock options 
granted under employment agreements (not to exceed 2,500 shares in the 
case of any one individual), whenever the Bank authorizes issuance of any 
class of stock or security, the securities shall first be offered ratably 
to the existing holders of shares of common or preferred stock, such rate 
of offer being the percentage of the total number of then-issued and 
outstanding shares of all classes of stock of the Bank held by such 
shareholder on the date the Bank authorizes the issuance.  The preemptive 
right may be exercised only with respect to the whole of the proportionate 
share available to the right holder and not as a part thereof.  For purposes 
of the ratable calculation, common and preferred stock shall be treated 
as outstanding stock of equal count.  The preemptive rights provided to 
stockholders of the Bank permit the purchase of shares on the same terms 
and conditions at which the Bank proposes to issue the securities to 
third parties, without deduction for any expenses of, or compensation for 
underwriting or purchase of such securities by underwriters or dealers.  
On the 10th day after the Bank authorizes the issuance of securities, the 
Bank shall give notice to each preemptive right holder of the number of 
shares available to the right holder and the terms of the proposed offering.  
Thereafter, the preemptive right holder has 15 days in which to purchase the 
securities at issue.  If the preemptive right holder declines to purchase 
the shares to which his or her preemptive rights attach, then those shares 
may be sold to third parties by the Bank in accordance with the terms of 
the offering.    

                                 62

Assessment

     All outstanding shares of Bank common stock are fully paid and 
nonassessable.  

     All shares of BankGroup common stock presently issued are, and those to 
be issued pursuant to the Agreement will be, fully paid and nonassessable.  

Conversion; Redemption; Sinking Fund

     Neither BankGroup common stock nor Bank common stock is convertible, 
redeemable or entitled to any sinking fund.  

Liquidation Rights

     Bank.  MDFI provides that a commercial bank may dissolve voluntarily, 
if the stockholders of the commercial bank and the Commissioner approve the 
dissolution.  A proposed voluntary dissolution shall be approved by the 
affirmative vote of the stockholders of the commercial bank who own two 
thirds of its capital stock.  After a proposed voluntary dissolution is 
approved by the stockholders, the board of directors of the commercial 
bank shall give the following notices.  The board shall give written notice 
to the Commissioner of the intended dissolution.  This notice shall be 
certified under the corporate seal of the commercial bank by its president 
and by its cashier or treasurer.  The board also shall give notice to 
creditors of the commercial bank to present for payment of any claim 
against it.  This notice shall be published once each week for 8 
consecutive weeks in a newspaper published in the county where the 
commercial bank has its principal banking office.  The Commissioner may 
approve the intended dissolution only if the Commissioner determines that 
the commercial bank is solvent.  

     The holders of the preferred stock of Bank are entitled to a liquidation 
preference in the event of a voluntary or involuntary liquidation, 
dissolution or winding up of the Bank, or any reduction in its capital 
resulting from any distribution of assets to its stockholders.  Holders of 
Bank preferred stock are entitled to receive in cash out of the assets of 
the corporation whether from capital or from earnings, available for 
distribution to its stockholders, before any amount is paid to the holders 
of common stock or of the stock of any other class ranking junior to the 
preferred stock, the sum of $21.00 per share.

     BankGroup.  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 

                                63
<PAGE>

or lesser vote.  There are no provisions in BankGroup's Articles which 
would modify the statutory requirements for dissolution under the VSCA.

Dividends and Other Distributions

     Bank.  The MDGCL 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 the indebtedness 
of the corporation as the indebtedness becomes due in the ordinary course 
of business, or (ii) the corporation's total assets would be less than the 
sum of the corporation's total liabilities plus, unless the charter permits 
otherwise, 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 stockholders whose preferential rights are 
superior to those receiving the distribution.  

     The holders of the preferred stock of Bank are entitled to a liquidation
preference in the event of a voluntary or involuntary liquidation, 
dissolution or winding up of the bank, or any reduction in its capital 
resulting from any distribution of assets to its stockholders.  Holders of 
Bank preferred stock are entitled to received in cash out of assets of the
corporation whether from capital or from earnings, available for distribution
to its stockholders, before any amount is paid to the holders of common 
stock or of the stock of any other class ranking junior to the preferred 
stock, the sum of $21.00 per share.  In addition to the MDGCL, there are 
various regulatory requirement which are applicable to distributions by a 
Maryland state-chartered, Federal Reserve member bank.  

     Further, by its charter, in the event the Board of Directors of Bank 
determines to declare dividends, the holders of Bank preferred stock shall 
be entitled to receive a non-cumulative dividend at a rate of $2.10 per 
share per annum, payable annually if, as and when determined by the Board 
of Directors, before any dividend shall be set apart or paid on any other 
capital stock for such year.  The holders of Bank preferred stock are also 
entitled to participate in dividends, if any, declared and paid by the 
Board of Directors to the holders of Bank common stock to the extent such 
dividends exceed the $2.10 per share preference amount.  

     BankGroup.  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 BankGroup's 
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 

                                64
<PAGE>

superior to those receiving the distribution.  These requirements are 
applicable to BankGroup as a Virginia corporation.

     In addition to the limitations set forth in the VSCA, there are various 
regulatory requirements which are applicable to distributions by bank 
holding companies.  For a description of the regulatory limitations on 
distributions by BankGroup, see "Supervision and Regulation Limits on 
Dividends and Other Payments."

Indemnification

     Bank.  To the full extent permitted by MDGCL, and any other applicable 
law, Bank shall indemnify a director or officer of Bank who is or was a 
party to any proceeding by reason of the fact that he is or was such a 
director or officer or is or was serving at the request of the Bank.  

     BankGroup.  To the full extent permitted by the VSCA and any other 
applicable law, BankGroup shall indemnify a director or officer of BankGroup 
who is or was a party to any proceeding by reason of the fact that he is 
or was such a director or officer or is or was serving at the request of 
the corporation, partnership, joint venture, trust, employee benefit plan 
or other enterprise.  The Board of Directors is empowered, by majority vote 
of a quorum of disinterested directors, to contract in advance to indemnify 
any director or officer.

Shareholder Proposals

     Bank.  Bank's Bylaws do not impose any restriction on matters which may 
come before any meeting of shareholders of Bank, provided proper prior 
notice of the meeting is given.  Written notice of all stockholders' 
meetings shall be given.  The notice of the annual meeting shall state 
that it is called for the purpose of the election of directors and 
for the transaction of other business which may properly come before the 
meeting and shall (if any other action which could be taken at a special 
meeting is to be taken at such annual meeting) state the purpose or 
purposes.  The notice of a special meeting shall in all instances state the 
purpose or purposes for which the meeting is called.  If any action is 
proposed to be taken which could, if taken, entitle stockholders to receive 
payment for their shares of stock, the notice must include a statement of 
that purpose and to that effect.  

      BankGroup.  BankGroup's Bylaws provide that at any meeting of 
shareholders of BankGroup, only that 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 

                                 65
<PAGE>

who has given written notice of business he expects to bring before 
the meeting to the Secretary of BankGroup not less than 90 days prior to
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 BankGroup's books, of the shareholder proposing 
such business, (c) the class and number of shares of BankGroup'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 shareholders except in accordance with the procedures set 
forth in BankGroup's Bylaws.

Shareholder Inspection Rights; Shareholder Lists

Bank.  Under the MDGCL, any stockholder, holder of a voting trust 
certificate in a corporation, or his agent may inspect and copy during 
usual business hours any of the following corporate documents:  
(i) bylaws; (ii) minutes of the proceedings of the stockholders; (iii) 
annual statements of affairs; and (iv) voting trust agreements on 
file at the corporation's principal office.  In addition, any 
stockholder or holder of a voting trust certificate in a corporation 
other than an open-ended investment company may present to any 
officer or resident agent of the corporation a written request for 
a statement showing all stock and securities issued by the corporation 
during a specified period of not more than 12 months before the date 
of the request.  Within 20 days after such a request is made under the 
MDGCL, the corporation must prepare and have available on file at its 
principal office a sworn statement of its president or treasurer or one of 
its vice presidents or assistant treasurers which states: (v) the number of 
shares or amounts of each class of stock or other securities issued during 
the specified period; (vi) the consideration received per share or unit, 
which may be aggregated as to all issuances for the same consideration 
per share or unit; and (vii) the value of any consideration other than 
money as set in a resolution of the board of directors.  Under the 
MDGCL, further and additional rights apply to stockholders of five percent 
or more of the outstanding stock of a Maryland corporation.  One or 
more persons who together are and for at least six months have been 
stockholders of record or holders of voting trust certificates of at least 
five percent of the outstanding stock of any class of a Maryland 
corporation may: (viii) in person or by agent, on written request, inspect 
and copy during usual business hours the corporation's books of 
account and its stock ledger; (ix) present to any officer or resident agent 
of the corporation a written request for a statement of its affairs; and (x) 
in the case of any corporation which does not maintain the original or a 
duplicate stock ledger at its principal office, present to any officer or 
resident agent of the corporation a written request for a list of its 
stockholders.  Within 20 days after a request for information is made by a 
five percent or more stockholder, the corporation must prepare and have 
available on file at its principal office; (xi) in the case of a request for 
a statement of affairs, a statement verified under oath by its president or 
treasurer or one of its vice-presidents or assistant treasurers which sets 
forth in reasonable detail the corporation's assets and liabilities as of a 
reasonably current date; and (xii) in the case of a request for a list of 
stockholders, a list verified under oath by one of its officers or its stock 
transfer agent or registrar which sets forth the name and address of each 
stockholder and the number of shares of each class which the stockholder 
holds.  

     BankGroup.  Under the VSCA, the shareholder of a Virginia corporation 
are entitled to inspect and copy certain books and records, including the 
articles of incorporation and bylaws of the corporation if he gives the 
corporation written notice of his or her demand at least five business 
days before the date on which he 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 six 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 he gives the corporation written notice of his or her demand 
at least five business days before the date on which he 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.

Shareholder Rights Plan

     Bank.  The Bank does not have in effect any Shareholder Rights Plan.  

     BankGroup.  For a description of a shareholder rights plan which has 
been adopted by BankGroup, see "Description of BankGroup Capital Stock -- 
Rights."

                                  66
<PAGE>

Dissenters' Rights

     Bank.  Under the applicable provisions of the Maryland General Corporation
Law, each holder of Bank stock will be entitled to demand and receive payment of
the fair value of his shares, if he (i) prior to or at the meeting, files with
the Bank a written objection to the Share Exchange, (ii) does not vote in favor
of the Share Exchange, and (iii) within 20 days after Articles of Share Exchange
have been accepted for record by the Maryland Department of Assessments and
Taxation (the "Department"), makes written demand on Bank for payment of his
shares, stating the number of shares for which payment is demanded.  A direction
in the stockholder's proxy to vote against the Share Exchange will not in itself
constitute a written objection or demand that satisfies the requirements
described above.  Any stockholder who fails to comply with the requirements
described above will be bound by the terms of the Share Exchange.

     Bank will promptly deliver or mail to each objecting stockholder written
notice of the date of acceptance of the Articles of Share Exchange for record
by the Department.  Bank may also deliver or mail to each objecting stockholder
a written offer to pay for his stock at a price deemed by Bank to be the fair
value thereof.  Within 50 days after acceptance of the Articles of Share
Exchange for record by the Department, either Bank or any objecting stockholder
who has not received payment for his shares may petition the court in Prince
George's County, Maryland, for an appraisal to determine the fair value
of such shares.  If the court finds that an objecting stockholder is entitled
to appraisal of his stock, the court will appoint three disinterested appraisers
to determine the fair market value of such shares on terms and conditions the
court determines proper, and such appraisers will, within 60 days after
appointment (or such longer period as the) court may direct), file with the
court and mail to each party to the proceeding their report stating their
conclusion as to the fair value of such shares.  Within 15 days after the filing
of such report, any party may object to such report and request a hearing
thereon.  The court will, upon motion of any party, enter an order either
confirming, modifying or rejecting such report and, if confirmed or modified,
enter judgment directing the time within which payment will be made.  If the
appraisers' report is rejected, the court may determine the fair value of the
shares of the objecting stockholders or may remit the proceeding to the same or
other appraisers.  Any judgment entered pursuant to a court proceeding will
include interest from the date of the stockholder's vote on the action to which
objection was made.  Costs of the proceeding shall be determined by the court
and may be assessed against Bank or, under certain circumstances, the objecting
stockholder, or both.

     At any time after the filing of a petition for appraisal, the court may
require objecting stockholders to submit their certificates representing shares
to the clerk of the court for notation of the pendency of the appraisal
proceedings.  A stockholder demanding payment for shares will not have the right
to receive any dividends or distributions payable to holders of record after the
close of business on the date of the stockholders' vote and will cease to have
any rights as a stockholder with respect to such shares except the right to
receive payment of the fair value thereof.
                                           
     BankGroup.  The provisions of Article 15 of the VSCA which provide 
shareholders of a Virginia corporation the right to dissent from, and 
obtain payment of the fair value of their shares in the event of, mergers, 
consolidations and certain other corporate transactions are applicable to 
BankGroup as a Virginia corporation.  However, because BankGroup has more 
than 2,000 record shareholders, shareholders of BankGroup generally do not 
have rights to dissent from mergers, consolidations and certain other 
corporate transactions to which BankGroup is a party because Article 15 of 
the VSCA 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.

                      RESALE OF BANKGROUP COMMON STOCK

     BankGroup Common Stock issuable in the Transaction has been registered 
under the 1933 Act, thereby allowing such shares to be traded freely and 
without restriction by those holders of Bank Common Stock who receive such 

                                 67
<PAGE>

shares following consummation of the Transaction and who are not deemed to 
be "affiliates" (as defined under the 1933 Act, but generally including 
directors, certain executive officers and 10% or more shareholders) of 
Bank or BankGroup.  Each holder of Bank Common Stock who is deemed by Bank 
to be an affiliate of it has entered into an agreement with BankGroup 
prior to the Effective Time of the Share Exchange providing, among other 
things, that (A) such affiliate acknowledges and agrees to support and 
vote such shares of Bank Common Stock beneficially owned by him to ratify 
and confirm the Agreement and the Share Exchange, (B) such affiliate 
acknowledges and agrees beginning 30 days prior to the Effective Time 
of the Share Exchange, that he will not sell, pledge, transfer 
or otherwise dispose of shares of Bank Common Stock or BankGroup Common 
Stock except in compliance with the applicable provisions of the 1933 
Act and rules and regulations thereunder and until such time as financial 
results covering at least 30 days of combined operations of BankGroup 
and Bank have been published within the meaning of Section 201.01 of the 
SEC's Codification of Financial Reporting Policies, and (C) 
the certificates representing said shares may bear a legend referring to 
the foregoing restrictions.  This Proxy Statement/Prospectus does not 
cover any resales of BankGroup Common Stock received by affiliates of Bank.

                   REPORT OF INDEPENDENT ACCOUNTANTS

To the Stockholders and the Board of Directors
Commerce Bank Corporation

     We have audited the accompanying balance sheets of Commerce 
Bank Corporation (the Bank) as of December 31, 1996 and 1995, and 
the related statements of operations, changes in stockholders' equity and 
cash flows for each of the three years in the period ended December 31, 
1996. These financial statements are the responsibility of the Bank's 
management. Our responsibility is to express an opinion on these financial 
statements based on our audits.

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

     In our opinion, the financial statements referred to above present 
fairly, in all material respects, the financial position of Commerce Bank 
Corporation as of December 31, 1996 and 1995, and the results of its 
operations and its cash flows for each of the three years in the period 
ended December 31, 1996 in conformity with generally accepted accounting 
principles.

                   COMMERCE BANK CORPORATION
                 NOTES TO FINANCIAL STATEMENTS

1.     Summary of Significant Accounting Policies:

Nature of Operations:

     Commerce Bank Corporation ("Commerce", "The Corporation" 
or "The Bank") operates from three locations in the Washington, D.C., 
metropolitan area. Commerce's primary source of revenue is derived from 
loans to customers.

Basis of Presentation:

     The accounting and reporting policies of Commerce are in accordance 
with generally accepted accounting principles and conform to prevailing 
practices within the commercial banking industry.

Management Estimates:

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

Investment Securities:

     The Bank divides the investment portfolio among three categories: 
securities held-to-maturity, securities available for sale and trading 
account securities. Debt securities that the Bank has the positive intent 
and ability to hold to maturity are reported at amortized cost. Securities 
available for sale are so designated for liquidity purposes and are reported 
at fair value with unrealized gains and losses shown as a separate component 
of stockholders' equity, net of the related tax effect.  Debt and equity 
securities that are bought and held principally for the purpose of selling 
them in the near term are classified as trading securities and reported at 
fair value with unrealized gains and losses included in earnings. The cost 
of securities sold is determined by the specific identification method. The 
Bank did not hold any securities classified as trading securities as of 
December 31, 1996 or 1995.

                       COMMERCE BANK CORPORATION
               NOTES TO FINANCIAL STATEMENTS, continued

Gains and losses on securities are realized in the period in which 
incurred.  Amortization and accretion of premiums and discounts are 
included in income over the contractual life of the securities.  

Loans and Allowance for Possible Loan Losses

Loans are stated at the principal amount outstanding. Interest income 
is accrued at the contractual rate on the principal amount outstanding. 
When scheduled principal or interest payments are past due 90 days or 
more on any loan, the accrual of interest income is discontinued. A loan 
remains on non-accrual status until the loan is current as to payment of 
both principal and interest and the borrower demonstrates the ability to 
pay and remain current.

Loan origination fees, net of origination costs, are deferred and 
recognized as an adjustment to interest income over the life of the 
related loan.

The Corporation adopted the provisions of Statements of Financial 
Accounting Standards No. 114/118 "Accounting by Creditors for 
Impairment of a Loan" ("SFAS No. 114/118") on January 1, 1995. 
Under SFAS No. 114/118, a loan is considered impaired, based on 
current information and events, if it is possible that Commerce will be 
unable to collect the scheduled payments of principal or interest when 
due according to the contractual terms of the loan agreement. The 
measurement of impaired loans is generally based on the present value 
of expected future cash flows discounted at the historical effective 
interest rate, except that all collateral dependent loans are measured 
for impairment based on the fair value of the collateral. Interest income 
on impaired loans is recognized on a cash basis. Impaired loans exclude 
smaller-balance homogenous loans such as residential mortgage and 
consumer installment loans which are collectively evaluated for impairment.

The Bank maintains an allowance for loan losses at an amount which, 
in management's judgment, should be adequate to absorb losses on existing 
loans that may become uncollectible. Management's judgment in determining 
the adequacy of the allowance is based on evaluations of the collectibility 
of loans. These evaluations take into consideration such factors as changes 
in the nature and volume of the loan portfolio, current economic conditions 
that may affect the borrowers' ability to pay, overall portfolio quality 
and review of specific problem loans.

The allowance for credit losses is established through charges to earnings in 
the form of a provision for credit losses. Increases and decreases in the 
allowance due to changes in the measurement of the impaired loans are

included in the provision for credit losses. Loans continued to be classified 
as impaired unless they are brought fully current and the collection of 
scheduled interest and principal is considered probable.

Bank Premises and Equipment:

Bank premises and equipment are stated at cost less accumulated 
depreciation and amortization. Depreciation and amortization are 
computed using the straight-line method over the estimated useful 
lives of the related property. Expenditures for maintenance, repairs 
and minor replacements are charged to operating expenses as incurred. 
Expenditures for improvements which extend the life of an asset are 
capitalized and depreciated over the asset's remaining useful life.

Cash and Cash Equivalents:

For purposes of reporting cash flows, cash and cash equivalents include 
cash and due from banks.

Income Taxes:

Deferred income taxes are provided with respect to temporary differences 
between the financial statement and tax basis of assets and liabilities using 
presently enacted tax rates.

Reclassifications:

Certain reclassifications have been made to the 1995 amounts to conform 
with 1996 presentation.

Short Term Borrowings:

The Banks Federal Funds limit in 1996 and 1995 was $2,400,000.

Earnings Per Share

Net income per share is calculated on the basis of the weighted average 
number of common and common equivalent shares outstanding for each 
of the three years in the period ended December 31, 1996.  Convertible 
preferred stock is considered a common stock equivalent in the earnings

                    COMMERCE BANK CORPORATION
           NOTES TO FINANCIAL STATEMENTS, continued

per share calculation.  Conversion of the stock purchase warrants in 1994 
would have been anti-dilutive; therefore, such conversion was not 
considered in the calculation for 1994.

Supplemental Cash Flow Information

Total interest paid in cash was $1,932,788, $1,617,025 and 
$1,103,094 for the years ended December 31, 1996, 1995 
and 1994, respectively.  Cash paid for income taxes was 
$968,337, $428,720 and $144,000 for the years ended 
December 31, 1996, 1995 and 1994, respectively.

New Accounting Pronouncements

SFAS No. 128 "Earnings per share" was issued in February 1997 and 
establishes standards for computing and presenting earnings per 
share and applies to entities with publicly held common stock or 
potential common stock.  The Statement is effective for financial 
statements issued for periods ending after December 15, 1997.  The 
adoption of the Statement would have changed earnings per share to 
basic earnings per share of $4.79 and diluted earnings per share of
$4.51 for the year ended December 31, 1996. 

SFAS No. 125 "Accounting for Transfers and Servicing of 
Financial Assets and Extinguishments of Liabilities" was issued 
in June 1996.  The standard had no significant impact on the earnings 
or the financial condition of the Corporation.  

2.      Restrictions on Cash:

The Federal Reserve requires banks to maintain cash reserves based 
principally on the amount of deposit liabilities. At December 31, 1996 
and 1995, the required reserve balance was $345,000 and $270,000, 
respectively.

$243,000, respectively, with a corresponding valuation allowance of 
$301,615 and $24,300, respectively.  For the years ended December 31, 
1996 and 1995, the average recorded investment in impaired loans was 
approximately $687,396 and $305,000, respectively.  Had all of these 
loans performed in accordance with their original terms, interest income 
of approximately $85,107 and $30,810 would have been recorded during

</TABLE>

The repurchase agreements consist of demand "Commerce Bank 
Repurchase Loans" which do not exceed ninety days from agreement 
date.  At December 31, 1996, the outstanding balances represented 
overnight borrowing transactions.  The Bank pays interest on these 
agreements at its daily fund rate (2.75% and 3.75% at December 31, 
1996 and 1995, respectively).  The average rates on these repurchase 
agreements for 1996 and 1995 were 2.86% and 3.05%, respectively.

8.	Convertible Preferred Stock:

Each share of the non-voting convertible preferred stock has a 
noncumulative dividend preference of $2.10 per share. Subject to 
federal and state regulatory approval, the preferred stock may be 
converted into common stock on a one-for-one basis. The Bank has 
reserved 30,984 shares of common stock for this purpose. The preferred 
stock is redeemable by the Bank under certain circumstances. The redemption 
price shall equal the greater of: the purchase price of the preferred stock 
plus interest accrued at the federal funds rate, fair market value as 
determined by an independent appraisal or two times the book value. In the 
event of a sale of all or substantially all of the Corporation's common 
stock, the acquirer must also purchase all of the preferred stock for the 
same price paid to holders of common stock. A related party holds 100% of 
the preferred shares of stock outstanding. If converted, the related entity 
would hold 18.18% of the outstanding common shares of the corporation.

9.     Stock Purchase Warrants:

The Bank issued to its founding investors warrants to acquire shares of 
common and convertible preferred stock for $21 per share during a ten-year 
period expiring September 1999. Based on their initial investments, founding 
investors were issued warrants to acquire 73,000 shares of common stock 
and 13,400 shares of convertible preferred stock.

The difference between the statutory tax rate and the effective tax rate of 
the Company is principally the result of the state income taxes net of the 
federal benefit.

At December 31, 1996, and 1995, no valuation allowance was 
required with respect to deferred tax assets.  

Net deferred income tax assets primarily arise from temporary differences 
generated from the reserve for loan losses and other accrued liabilities.

12.     Credit Risk:

Various commitments to extend credit (lines of credit) are made 
in the normal course of banking business. Letters of credit are also 
issued for the benefit of customers. These commitments involve, to 
varying degrees, elements of credit and market risk which may 
exceed any amount recognized in the financial statements. In making 
such commitments, the Corporation uses the same underwriting policies 
as it uses for loans outstanding.

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 many of the commitments 
are expected to expire without being drawn upon, the total commitment 
amounts do not necessarily represent future cash requirements. 
Commitments to extend credit at December 31, 1996 and 1995 totaled 
$9,108,000 and $10,433,000, respectively.

Conditional commitments are issued by the Bank in the form of 
stand-by letters of credit which guarantee the performance of a customer 
to a third-party. At December 31, 1996 and 1995, commitments 
under outstanding stand-by letters of credit aggregated $598,340 
and $1,007,507, respectively. Of these balances, $97,026 and $814,191 
of the outstanding balances are collateralized. The remaining letters of 
credit are uncollateralized.

A significant portion of the Bank's loan customers are located within 
the State of Maryland, primarily in the College Park area.

At December 31, 1996 and 1995, cash and due from banks includes 
$622,091 and $493,163, respectively, on deposit with a single depository 
institution insured up to the federal guidelines set for depository financial 
institutions.

13.     Regulatory Matters:

The Bank is subject to various capital adequacy guidelines imposed by 
federal and state regulatory agencies.  Under these guidelines, the Bank 
must meet specific capital adequacy requirements which are quantitative 
measures of the Bank's assets, liabilities and certain off balance sheet 
items calculated under regulatory accounting practices.  Additionally, 
the Bank's capital amounts and classifications are subject to qualitative 
judgments by these agencies about components, risk weightings and 
other factors.  The quantitative measures established by regulation to 
ensure capital adequacy require the

<PAGE>

                        COMMERCE BANK CORPORATION
                 NOTES TO FINANCIAL STATEMENTS, continued

Bank to maintain amounts and ratios of total and tier I capital to risk-
weighted assets and tier I capital to average assets, known as the leverage 
ratio.  The Bank's tier I capital is equal to its common stock, surplus and 
retained earnings.  Equity for regulatory purposes does not include market 
value adjustments for available for sale securities.  The calculation of the 
Bank's total capital is equal to tier I capital plus the allowance for loan 
losses subject to certain limitations.  Risk-weighted assets are determined 
by applying weighting to asset categories and certain off-balance sheet 
commitments based on the level of credit risk inherent in the assets.  At 
December 31, 1996, the Bank exceeds all regulatory capital requirements.  
The most recent notification from the Bank's primary regulators categorized 
the Bank as well capitalized under the regulatory framework for prompt 
corrective action.  There are no conditions or events since that management 
believes have changed the Bank's category.  If the Bank is unable to comply 
with the minimum capital requirements, it would result in regulatory 
actions which could have a material impact on the Bank.

The minimum regulatory guidelines for total capital and tier I capital to 
risk weighted assets are 8% and 4%, respectively.  Guidelines for the 
leverage ratio require the ratio of tier I capital to average assets to be 
100 to 200 basis points above a 3% minimum, depending on risk profiles 
and other factors.  The table below presents the various components used 
to calculate the capital adequacy ratios.

14.     Thrift Plan:

Effective January 1, 1994, the Bank has a defined contribution retirement 
plan (the Plan) which qualifies under Section 401(k) of the Internal Revenue 
Code.  Bank employees are eligible to participate in the Plan after completion 
of one year of service and attainment of age twenty-one.  The Plan allows all 
participants to contribute up to 15% of their compensation to the Plan up 
to statutory limits.  The Bank may also make annual matching

               NOTES TO FINANCIAL STATEMENTS, continued

contributions to the Plan at the discretion of the Board of Directors of 
the Bank.  Employees vest in the Bank's matching contributions at the 
rate of 20% for each year of service after the first year of service, with 
full vesting upon six years of service.  The Bank contributed $25,619, 
$21,911 and $16,884 to the Plan for the years ended December 31, 
1996, 1995 and 1994, respectively.

15.     Subsequent Event:

The Bank entered into an agreement on July 3, 1997 with MainStreet 
BankGroup Incorporated ("MSBC") whereby the Bank will become 
a wholly owned subsidiary of MSBC through an exchange of all the 
issued and outstanding shares of convertible preferred and common stock of 
the Bank and the outstanding Warrants for shares of common stock of MSBC.  
Upon shareholder and various regulatory approvals, the Bank will be merged 
into MSBC using the pooling-of-interest accounting method.  The transaction 
is expected to be finalized in the fourth quarter of 1997.

RECITALS:
     (A)  MSBC.  MSBC is a corporation duly organized and existing in

Stock have preemptive rights.  CB does not have any subsidiary corporations 
or other entities.  CB Common Stock is not and never has been subject to 
the provisions of Section 12, 13, 14(a), 14(c), 14(d), 15(d) or 16 of the 
Securities Exchange Act of 1934, as amended, (together with the rules 
and regulations promulgated thereunder, the "Exchange Act") nor has 
CB ever been nor is it now subject to Section 12 of the Exchange Act and 
the regulations of the Office of the Comptroller of the Currency, the

Deposit Insurance Corporation ("FDIC") or the Securities and Exchange 
Commission ("SEC") thereunder.  CB is not subject to regulation under 
12 CFR, Section 11, Section 206 or Section 335, and does not file and 
has never filed any reports or disclosures pursuant thereto.

     (C)  Rights, Etc.  Except as Previously Disclosed, there are no 
shares of MSBC Common Stock or MSBC Preferred Stock authorized 
and reserved for issuance, and MSBC has no commitment to authorize, 
issue or sell any such shares or any securities or obligations convertible 
into or exchangeable for, or giving any person any right to subscribe for or 
acquire from MSBC, any such shares and no securities or obligations 
representing any such rights are outstanding.  Except as Previously 
Disclosed, MSBC has not granted or made any commitment to grant any 
options or share appreciation rights with respect to the MSBC Common 
Stock or MSBC Preferred Stock.  Except as Previously Disclosed and 
except for shares reserved pursuant to the Stock Option Agreement (as 
hereinafter defined), there are no shares of CB Common Stock or CB 
Preferred Stock or any CB Warrants authorized and reserved for issuance.  
Except as Previously Disclosed, CB has no commitment to authorize, 
issue or sell any shares of CB Common Stock or of CB Preferred Stock, 
CB Warrants or any other securities or obligations convertible into or 
exchangeable for, or giving any right to subscribe for or acquire from 
CB any such shares, CB Warrants or securities and no securities or 
obligations representing any such rights are outstanding.  Except as 
Previously Disclosed and except for the Stock Option Agreement (as 
hereinafter defined), CB has not granted or made any commitment to grant 
any options or share appreciation rights with respect to CB Common Stock 
or CB Preferred Stock.  

     (D)  This Transaction.  MSBC will, on the Share Exchange Effective 
Date, acquire and own 100% of the outstanding shares of CB Common 
Stock (which, apart from the shares of CB Preferred Stock escrowed 
pursuant to Paragraph (R) of Article VI, shall be the only shares of capital 
stock of CB outstanding at the Share Exchange Effective Date) by virtue 
of an exchange of shares of MSBC Common Stock for all the issued and 
outstanding shares of CB Common Stock (excluding only the Excluded 
Shares) as more particularly described in Article I) and the Boards of 
Directors of MSBC and CB, respectively, deem it advisable and in the 

                                A-2
<PAGE>

best interests of MSBC and CB and their stockholders that CB be acquired 
by MSBC pursuant to this Agreement and Plan of Share Exchange.  

     (E)  Stock Option Agreement.  As a condition and inducement to 
MSBC's willingness to enter into the letter of intent dated June 24, 
1997, contemplating this Plan, CB has entered into a Stock Option 
Agreement with MSBC dated June 24, 1997 ("Stock Option Agreement") 
pursuant to which CB has granted to MSBC an option to purchase, under 
certain circumstances, shares of CB Common Stock.  

     (F)  Approvals.  The Board of Directors of each of MSBC and CB has 
approved and adopted, at meetings of each of such Board of Directors, 
this Plan and the Stock Option Agreement and has authorized, subject to 
such further modifications as may be agreed by a member of the Office 
of the Chairman of MSBC and the President or Chairman of the Board 
of CB, respectively, not inconsistent herewith, the execution hereof in 
counterparts.  At the meeting of the CB Board of Directors, the Board of 
Directors of CB unanimously recommended the Plan as so executed to 
its shareholders.

     (G)  NASDAQ.  Trading of the MSBC Common Stock is presently 
reported on the National Association of Securities Dealers Quotations 
System National Market System("NASDAQ/NMS").  Trading of the 
CB Common Stock is not presently reflected on any exchange, established 
market, bulletin board or otherwise.  Neither the CB Preferred Stock nor 
the CB Warrants are traded on any established market.  

     (H)  Benefits of Plan.  MSBC and CB believe the Plan and its 
consummation are in the respective best interests of each corporation 
and its shareholders for the following reasons, among others:  (1) the 
Share Exchange will allow them to provide banking and related financial 
services more effectively and efficiently; (2) the Share Exchange will 
expand the range of banking and related financial services which they 
can provide; (3) the Share Exchange will enhance the safety and 
soundness of their operations; (4) the Share Exchange will enable them 
to expand the market for their banking and related financial services; 
and (5) the Share Exchange will expand the number and diversity of 
CB's shareholder base and enhance the liquidity of equity investments 
in CB.

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

                    	I.  THE SHARE EXCHANGE

     (A)  The Share Exchange.  On the Share Exchange Effective Date 
(as hereinafter defined), CB shall become a wholly owned subsidiary 

                                 A-3
<PAGE>

bank of MSBC by virtue of a share exchange in which all of the capital 
stock of CB (as represented by all of the issued and outstanding shares 
of CB Common Stock (excluding only the Excluded Shares) which, 
apart from the shares of CB Preferred Stock escrowed pursuant to 
Paragraph (R) of Article VI, shall be the only class or series of stock of 
CB outstanding as of Share Exchange Date) shall be acquired from the 
holders thereof through a statutory share exchange (the "Share Exchange") 
in which each outstanding share of CB Common Stock shall be converted 
into the right to receive the consideration described in Paragraph (B) 
and (D) of Article II.

     (B)  Share Exchange Closing; Share Exchange Effective Date.  The Share 
Exchange shall become effective on the date and time the Maryland 
Department of Assessments and Taxation ("Maryland Corporation 
Authority") accepts the Articles of Share Exchange as approved by 
the Maryland Commission of Financial Regulations ("Maryland Bank 
Regulator") (the " Share Exchange Effective Date").  Unless otherwise 
agreed upon in writing by a member of the Office of the Chairman of 
MSBC and President of CB, subject to the conditions to the obligations 
of the parties to effect the Share Exchange as set forth in Article VI and 
taking into account Paragraph H of Article II, the parties shall use their 
reasonable efforts to cause the Share Exchange Effective Date to occur 
as soon as practicable following the satisfaction of the conditions set 
forth in Paragraphs (A), (B) and (C) of Article VI.  All documents 
required by the terms of this Agreement to be delivered at or prior to 
consummation of the Share Exchange will be exchanged by the parties 
at the closing of the Share Exchange(the "Share Exchange Closing"), 
which shall be held on such date as MSBC shall designate to CB (and 
which is reasonably acceptable to CB) after the satisfaction of the 
conditions set forth in Paragraphs (A), (B) and (C) of Article VI 
and taking into account the provisions of Paragraph (H) of Article 
II, but no later than the Share Exchange Effective Date.  Prior to 
the Share Exchange Closing, MSBC and CB shall execute and 
deliver to the Maryland Bank Regulator, Articles of Share Exchange 
in substantially the form of Exhibit A hereto containing a Plan of 
Share Exchange in substantially the form of Annex 1 to Exhibit A 
hereto (the "Plan of Share Exchange ") for approval.

                   II.  SHARE EXCHANGE RIGHTS

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

     (B)  Outstanding CB Common Stock.  Each share (excluding shares 
held by CB or by MSBC or by any of the MSBC Subsidiaries, in each 
case other than in a fiduciary capacity or as a result of debts previously 

                                 A-4
<PAGE>

contracted and excluding shares held by stockholders who perfect their 
dissenters' rights as provided in Paragraph (F) below (the "Excluded 
Shares")) of CB Common Stock issued and outstanding immediately prior 
to the Share Exchange Effective Date shall, by virtue of the Share 
Exchange, automatically and without any action on the part of the 
holder thereof on the Share Exchange Effective Date, become and be 
converted into the right to receive ("Exchange Rights") that number of 
shares of MSBC Common Stock obtained by dividing the Negotiated 
Price per CB Common Share by the average of the bid/asked price per share 
for MSBC Common Stock as reported on the NASDAQ/NMS for each 
of the twenty (20) trading days preceding the later to occur of (i) the 
shareholder approval(s) contemplated by Paragraph A of Article VI 
and (ii) the financial institution regulatory approvals (but not the 
statutory waiting periods) contemplated by Paragraph B of Article VI 
("Average MSBC Share Price").  If the Exchange Ratio computed in accordance 
with the immediately preceding sentence is less than 2.059, the Exchange 
Ratio shall be 2.059, and if the Exchange Ratio computed in accordance 
with the immediately preceding sentence is greater than 2.506, the 
Exchange Ratio shall be 2.506 ("Exchange Ratio").  The Negotiated 
Price per CB Common Share is $52.00.

     (C)  Stockholder Rights; Stock Transfers.  On the Share Exchange 
Effective Date, holders of CB Common Stock shall cease to be, and 
shall have no rights as, stockholders of CB other than the Exchange 
Rights provided under Paragraph (B) above and the consideration for 
fractional shares provided under Paragraph (D) below.  After the Share 
Exchange Effective Date, there shall be no transfers on the stock transfer 
books of CB of the shares of CB Common Stock which were issued and 
outstanding immediately prior to the Share Exchange 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 
Share Exchange; instead, MSBC shall pay to each holder of CB 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)  Dissenting Shareholders.  Any holder of shares of CB Common 
Stock or of CB Preferred (to the extent any such holders as a matter of 
law are provided with dissenters' rights) who perfects his dissenters' rights 
of appraisal in accordance with and as contemplated by the applicable 
provisions of the Maryland Corporation Law shall be entitled to receive 
the value of such shares in cash as determined pursuant to such provision 
of law; provided, however, that no such payment shall be made to any 
dissenting stockholder unless and until such dissenting stockholder has 
complied with the applicable provisions of the Maryland Corporation 
Law and duly surrendered the certificate or certificates representing the 
shares for which payment is being made.  In the event that a dissenting 

                                 A-5
<PAGE>
stockholder of CB having dissenters' rights as a matter of law fails to 
perfect, or effectively withdraws or loses, his right to appraisal and of 
payment for his shares, after the Share Exchange Effective Date MSBC 
shall issue and deliver the consideration to which such holder of shares 
of CB Common Stock is entitled under this Article I (without interest) 
upon surrender by such holder of the certificate or certificates representing 
shares of CB Common Stock or CB Preferred Stock, as the case may be, 
held by him.  

     (F)  Exchange Procedures.  As promptly as practicable after the Share 
Exchange Effective Date, MSBC shall send or cause to be sent to each 
former stockholder of CB of record immediately prior to the Share 
Exchange Effective Date transmittal materials for use in exchanging 
such stockholder's certificates of CB for the consideration set forth in 
Paragraph (C) above.  Any fractional share checks which a CB stockholder 
shall be entitled to receive in exchange for such stockholder's shares of 
CB 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 CB Common Stock will be delivered to 
such stockholder only upon delivery to MSBC 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 Share 
Exchange Effective Date, to the extent permitted by law, former stockholders 
of record of CB Common Stock shall be entitled to vote at any meeting 
of holders of MSBC Common Stock, the number of whole shares of 
MSBC Common Stock to which they have Exchange Rights, regardless 
of whether such holders have exchanged their certificates representing 
CB Common Stock for certificates representing MSBC Common 
Stock in accordance with the provisions of this Plan.

     (G)  Shares Held by CB or MSBC.  Each of the shares of CB Common 
Stock held by CB, by MSBC or any MSBC Subsidiary, in each case other 
than in a fiduciary capacity or as a result of debts previously contracted, 
shall be canceled and retired at the Share Exchange Effective Date and 
no consideration shall be issued in exchange therefor.

     (H)  Dividends.  Shareholders of CB shall not under any circumstances 
be entitled to any dividend (cash or otherwise) declared by MSBC with 
a record date prior to the Share Exchange Effective Date.  MSBC and 
CB agree that CB may pay an annual, one time cash dividend per share 
on CB Common Stock in 1997 not exceeding $1.50 times the percentage 
obtained by dividing four (4) into the number of quarters elapsed in the 
year as of the record date for such dividend, including the quarter in 
which such record date accrues.  In the event that CB declares and pays 
a dividend in accordance with the immediately preceding sentence, CB 
and MSBC agree that the Share Exchange Effective Date and the Share 

                                A-6
<PAGE>

Exchange Closing may be adjusted so that the holders of CB Common 
Stock shall not become entitled as holders of MSBC Common Stock 
pursuant to this Plan to any quarterly cash dividend declared or payable 
by MSBC for any quarter which was also a quarter for which a CB 
dividend was paid using the formula in the immediately preceding sentence.

             III.  ACTIONS PENDING THE SHARE EXCHANGE

     CB hereby covenants to MSBC, and MSBC hereby covenants 
to CB, that:

     (A)  Best Efforts to Complete Share Exchange.  Subject to the 
terms and conditions of this Plan, it shall use its best efforts in 
good faith to take, or cause to be taken, all actions, and to do, or 
cause to be done, all things necessary, proper or desirable, or 
advisable under applicable laws, as promptly as reasonably practicable 
so as to permit consummation of the Share Exchange as soon as 
reasonably practicable 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 herein and in the Stock Option Agreement and to cause 

                                A-17
<PAGE>

to be satisfied the conditions referred to in Article VI and in the Stock 
Option Agreement, and each of CB and MSBC shall use, and 
MSBC shall cause the MSBC Subsidiaries to use, their respective best 
efforts to obtain all consents (governmental or other) necessary or 
desirable for the consummation of the transactions contemplated by this 
Plan and the Stock Option Agreement; and (2) in the case of CB, cooperating 
with MSBC in supplying such information as MSBC may reasonably request 
in connection with any public offerings of securities by MSBC prior to the 
Share Exchange Effective Date; 

     (B)  CB Proxy Statement.  In the case of CB only,  (1)  it shall 
promptly prepare and provide to MSBC prior to its filing and mailing 
a proxy statement (the "Proxy Statement") to be mailed to the holders 
of CB Common Stock (and, if required, the holders of CB Preferred 
Stock) in connection with the Share Exchange 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 thereto is mailed to holders of CB Common 
Stock (and, if required, the holders of CB Preferred Stock) and at all 
times thereafter up to and including the meeting of CB shareholders 
referred to in Subparagraph (3) of this Paragraph (B), the Proxy Statement 
and such amendments and supplements will comply in all material 
respects with the 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 CB Common Stock (and, if required, the holders of CB 
Preferred Stock) as soon as practicable after the Registration Statement 
has become effective for purposes of voting upon this Plan, the Plan of 
Share Exchange and the Share Exchange contemplated hereby and 
thereby, and (4) subject to the fiduciary duties of the Board of Directors 
of CB (as advised in writing by its counsel), it shall use its best efforts 
to solicit and obtain votes of the holders of CB Common Stock (and, 
if required, the holders of CB Preferred Stock) in favor of the above 
proposals and shall once, at MSBC's request, recess or adjourn the 
Meeting if such recess or adjournment is deemed by MSBC to be 
necessary or desirable;

     (C)  Registration Statement Contents.  When the Registration 
Statement or any post-effective amendment or supplement thereto 
shall become effective, and at all times subsequent to such 
effectiveness, up to and including the date of the Meeting, such 
Registration Statement and all amendments or supplements thereto, 
with respect to all information set forth therein furnished or to be 
furnished by CB relating to CB and by MSBC relating to MSBC 
and the MSBC Subsidiaries (1) will comply in all material respects 

                                 A-18
<PAGE>

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 
Statement, each will cooperate with the other and will furnish the 
information concerning itself required by law to be included therein;

     (D)  Effectiveness of Registration Statement.  MSBC will advise 
CB, promptly after MSBC receives notice thereof, of the time when 
the Registration Statement has become effective or any supplement 
or amendment has been filed or of the issuance of any stop order 
or the suspension of the qualification of the MSBC Common Stock 
for offering or sale in any jurisdiction, of the initiation or threat of 
any proceeding for any such purpose, or of any request by the SEC 
for the amendment or supplement of the Registration Statement 
or for additional information;

     (E)  Public Announcements.  It agrees that, unless approved 
by the other party hereto in advance, it will not issue any press 
release or written statement for general circulation relating to 
the transactions contemplated hereby, except as otherwise required 
by law or applicable NASD or stock exchange rule; 

     (F)  Review of Information.  (1) Upon reasonable notice, it 
shall afford the other party hereto, and its officers, employees, 
counsel, accountants and other authorized representatives, 
access, during normal business hours throughout the period 
prior to the Share Exchange Effective Date, to all of its properties, 
books contracts, commitments and records and, during such period, 
it shall 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, provided that no 
investigation pursuant to this Paragraph (F) by any party 
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; and (2) each party hereto will not use 
any information obtained pursuant to this Paragraph (F) for any 
purpose unrelated to the consummation of the transactions 

                                 A-19
<PAGE>

contemplated by this Plan and the Stock Option Agreement 
and, if the Share Exchange is not consummated, will hold all 
information and documents obtained pursuant to this paragraph 
in confidence (as provided in Paragraph (F) of Article VIII) 
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, and 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 CB only, (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) 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; and (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; 

     (H)  Filing of Registration Statement.  In the case of MSBC 
only, it shall, as promptly as practicable following the date of 
this Plan, prepare and file the Registration Statement with the 
SEC and MSBC shall use its best efforts to cause the Registration 
Statement to be declared effective as soon as practicable after 
the filing thereof;

     (I)  Blue Sky.  In the case of MSBC only, it shall use its best 
efforts to obtain, prior to the effective date of the Registration 
Statement, all necessary Blue Sky Law permits and approvals, 
provided that MSBC shall not be required by virtue thereof 
to submit to general jurisdiction in any state;

     (J)  Affiliates.  In the case of CB only, within 30 days after 
the execution of this Plan it will cause each person who may 
be deemed to be an "affiliate" of it for purposes of Rule 145 
under the Securities Act to execute and deliver to MSBC an 
agreement in the form attached hereto as Exhibit B;

     (K)  CB Policies and Practices.  In the case of CB only: 
CB shall use its best efforts to modify and change its credit, 
investment, litigation, real estate valuation and trust department 
policies and practices (including loan classifications and levels 
of reserves) prior to the Share Exchange Closing so as to be 
 
                                 A-20
<PAGE>

consistent on a mutually satisfactory basis with those of MSBC 
and generally accepted accounting principles.  CB shall not be 
required to modify or change any policies or practices, however, 
until (x) satisfaction of the conditions set forth in Paragraphs (A), 
(B) and (C) of Article VI, (y) such time as CB and MSBC shall 
reasonably agree that the Share Exchange 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 (2) such time as MSBC acknowledges in writing 
that all conditions to MSBC's obligation to consummate the Share 
Exchange (and MSBC's rights to terminate this Plan) have been 
waived or satisfied; provided, however, that in all circumstances 
CB shall make such modifications and changes not later than 
immediately prior to the Share Exchange Effective Date.  CB'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);

     (L)	State Takeover Laws.  In the case of CB only, it shall not 
take any action that would cause the transactions contemplated by 
this Plan and/or the Stock Option Agreement to be subject to any 
applicable state takeover, business combination, control share 
acquisition or similar statute in effect as of the date of this Plan 
and shall take all necessary steps to exempt (or ensure the continued 
exemption of) the transactions contemplated by this Plan and the 
Stock Option Agreement from, or if necessary challenge the validity 
or applicability of, any applicable state takeover, business combination, 
control share acquisition or similar law, as now or hereafter in effect, 
including, without limitation, Title 3, Subtitle 6 and Title 3, Subtitle 
7, of the Maryland Corporation Law;

     (M)  CB Special Shareholder Rights.  In the case of CB 
only:  (1) it shall take all necessary steps to ensure 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 Share Exchange 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 of Bylaws of CB or under any 
agreement to which CB is a party (except for employment contracts and 
benefits Previously Disclosed); or (2) restrict or impair in any way the 
ability of MSBC to exercise the rights granted hereunder or under the 
Stock Option Agreement;

     (N)   CB Shareholder Approval Rights.  In the case of CB, only, 
it shall not adopt any plan or other arrangement that would adversely 
affect in any way MSBC's rights under this Plan or the Stock Option 
Agreement;

                                 A-21
<PAGE>

     (O)  Best Efforts for Share Exchange.  It undertakes and agrees to 
use its best efforts to cause the Share Exchange to be effected and to 
take no action which would cause the Share Exchange to fail to 
qualify for pooling of interests accounting treatment;

     (P)  Government Applications.  In the case of MSBC only, it 
shall promptly seek the following consents and approvals with 
respect to the Share Exchange: (1) approval of the Share Exchange 
by the FRB under Section 3 of the Bank Holding Company Act 
("FRB Acquisition Approval"); (2) approval of the Share Exchange by 
the Maryland Bank Regulator ("Maryland Bank Regulator Acquisition 
Approval"); and (3) approval of the Share Exchange by the Bureau of 
Financial Institutions of the Virginia State Corporation Commission 
("Virginia Bank Regulator Acquisition Approval").  Both MSBC and 
CB will use their best efforts to obtain and will cooperate with each 
other in making applications for the foregoing approvals or other 
actions advisable in the reasonable judgment of MSBC to consummate 
the Share Exchange 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 CB of the transactions contemplated by 
this Plan so as to render inadvisable the consummation of the Share 
Exchange; 

     (Q)  Environmental Tests.  CB will allow MSBC to conduct, 
through designated representatives, environmental and engineering 
tests provided that no test or information discovered pursuant thereto 
shall be deemed to affect or modify or waive any representation or 
warranty made by CB.

<PAGE>

hereof, manually signed by a member of the Office of the Chairman 
describing specifically the number of Warrants and the holder of the

agreement with CB for the express benefit of and reasonably acceptable 
to MSBC to redeem as of the Share Exchange Closing each CB Warrant 
in return for that number of shares of MSBC Common Stock equal to 
the quotient obtained by dividing $31.00 by the Average MSBC Share 
Price ("Warrant Redemption Ratio").  If the Warrant Redemption Ratio 
computed in accordance with the immediately preceding sentence is

of the Share Exchange Closing all issued and outstanding shares of CB

based on this Paragraph.  As of the Share Exchange Closing, the holders 
of CB Preferred Stock and CB Warrants shall by agreement be entitled 
only to receive from MSBC the shares of MSBC Common Stock as 
provided in the agreements executed in accordance with this Paragraph 
and shall have no further rights under the terms of the CB Preferred Stock 
and CB Warrants, which shall be considered redeemed, as the case may 
be, as of the Share Exchange Closing, provided, however, that a failure 
to satisfy any of the conditions set forth in the proviso following Paragraph 
(C) or in Paragraph (F), (H), (J), (L), (P), or (R) of Article VI shall only 
constitute conditions if asserted by MSBC and a failure to satisfy any of 
the conditions set forth in the proviso following Paragraph (C), Paragraph 
(E), (G), (I), or (Q) of this Article VI shall only constitute conditions if 
asserted by CB.

                          VII.  TERMINATION.

     This Plan may be terminated as follows prior to the Share 
Exchange Effective Date, either before or after receipt of required 
stockholder approval, provided that termination under this Article VII 
shall not relieve any party from liability under Paragraph (E) of Article VIII:

if the Board of Directors of each so determines by vote of a majority of 
the members of its entire Board;

        (B)  On Breach.  By MSBC or CB, if its Board of Directors 
so determines by vote of a majority of the members of its entire 

                                A-26
<PAGE>

Board, in the event of (1) a breach by the other party of any representation 
or warranty contained herein, which breach cannot be or has not been cured 
within thirty (30) days after the giving of written notice to the breaching 
party of such breach and which breaches, individually or in the aggregate, 
materially adversely affect the Share Exchange and the other transactions 
contemplated by this Plan, or (2) a material breach by the other party of 
any of the covenants or agreements contained herein, which breach 
cannot be or has not been cured within thirty (30) days after the giving 
of written notice to the breaching party of such breach; provided, however, 
that a breach can only be asserted as a basis for termination pursuant to 
this paragraph (B) by a party who is not itself at such time in breach hereof;

        (C)  Failure to Consummate on Time.  By MSBC or CB, if its 
Board of Directors so determines by vote of a majority of the members 
of its entire Board, in the event that the Share Exchange is not 
consummated by December 31, 1997;

        (D)  Failure to Obtain Certain Approvals.  By MSBC or CB, if 
its Board of Directors so determines by a vote of a majority of the 
members of its entire Board, in the event that (1) any common stockholder 
approval contemplated by Paragraph (A) of Article VI is not obtained at 
a meeting or meetings called for the purpose of obtaining such approval; 
(2) FRB Acquisition Approval, the Maryland Bank Regulator Acquisition 
Approval, the Virginia Bank Regulator Acquisition Approval or any 
other financial institution regulatory approval, to the extent necessary 
to consummate the Share Exchange legally, is finally and unconditionally 
denied; 

        (E)  Possible Adjustment in Exchange Rate and Warrant Redemption 
Ratio.  By CB by vote of a majority of the members of its entire Board 
during the ten (10) day period commencing on the Determination Date 
if both of the following conditions are satisfied:

                  (1)  if the Average MSBC Determination Price for MSBC 
Common Stock on the Determination Date is less than $20.75; 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 CB elects to exercise its 
termination right pursuant to Paragraph (E) 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 CB Common Stock by adjusting the Exchange Ratio and to increase 
the consideration to be received by the holders of the CB Warrants in the 
 redemption thereof pursuant to Paragraph (R)of the Article VI to equal a 

                                 A-27
<PAGE>

quotient, the numerator of which is $20.75 multiplied by the Exchange 
Ratio (as then in effect) in the case of the holders of CB Common Stock 
or by the Warrant Redemption Ratio in the case of holders of CB 
Warrants and the denominator of which is the Average MSBC 
Determination Price.  If MSBC makes the election contemplated by the 
immediately preceding sentence, it shall give prompt written notice to 
CB of such election and the revised Exchange Ratio and revised Warrant 
Redemption Ratio, whereupon no termination shall have accrued pursuant 
to this Paragraph (E) and the Plan shall remain in effect in accordance 
with its terms (except as the Exchange Ratio and Warrant Redemption 
Ratio shall have been so modified) and any references in this Plan to 
"Exchange Ratio" or "Warrant Redemption Ratio" shall thereafter be 
deemed to refer to the Exchange Ratio or Warrant Redemption Ratio as 
adjusted pursuant to this Paragraph (E).  

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

      "Average MSBC Determination Price" means the average of the 
bid/ask price for MSBC Common Stock as reported on the 
NASDAQ/NMS for the 20 consecutive full trading days preceding 
the Determination Date.

       "Determination Date" means the tenth day prior to the Share 
Exchange Closing.

        "First Percentage" means the percentage resulting from: (a) taking 
the remainder ("First Remainder") obtained by subtracting the Average 
 MSBC Determination Price from $23.625 (the average of the bid and 
asked prices of MSBC Common Stock as reported on the NASDAQ/NMS 
on June 18, 1997; and (b) dividing the First Remainder by the Average 
MSBC Determination 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 Determination 
Price ("Recent SNL Bank Index") from the SNL Southeast Bank Index at 
June 18, 1997; and (b) dividing the Second Remainder by the Recent 
SNL Bank Index.

        (F)  Failure to Redeem CB Preferred Stock and CB Warrants.  
By MSBC, if, at least 30 days prior to Share Exchange Closing, CB shall 
not have caused the holders of all outstanding shares of CB Preferred 
Stock and all CB Warrants (excepting only CB Warrants excluded from 
the escrow requirements of Paragraph (R) of Article VI expressly by the 
terms thereof) to deposit with an escrow agent mutually acceptable to CB 
and MSBC all shares of CB Preferred Stock and all CB Warrants required 
to be redeemed together with agreements and other documents required by 
Paragraph (R) of Article VI necessary and sufficient to enable and require 

                                 A-28
<PAGE>

the redemption of the CB Preferred Stock and the CB Warrants and to obligate 
the holders thereof to redeem as of the Share Exchange Closing all issued and 
outstanding shares of CB Preferred Stock and all such CB Warrants, 
respectively, in return for the shares of MSBC Common Stock to which they 
are entitled as provided in Paragraph (R) of Article VI.

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

               (1)  the term "knowledge" when used with respect to a party 
shall mean the knowledge, after due inquiry, of any "Executive Officer" 
of such party as such term is defined in FRB Regulation O;

                (2)  the term "Material Adverse Effect," when applied to a 
party, shall mean an event, occurrence or circumstance (including 
without limitation (a) the making of any provisions for possible loan 
and lease losses, write-downs of other real estate and taxes and (b) 
any breach of a representation or warranty by such party) which (i) 
has or is reasonably likely to have a material adverse effect on the 
financial position, results of operations or business of the party and 
its subsidiaries, taken as a whole, or (ii) would materially impair the 
party's ability to perform its obligations under this Plan or the 
consummation of the Share Exchange and the other transactions 
contemplated by this Plan; provided, however, that, solely for purposes 
of measuring whether an event, occurrence or circumstance has a material 
adverse effect on such party's results of operations, the term "results of 
operations" shall mean net interest income plus non-interest income 

                                 A-31
<PAGE>

(less securities gains) less gross expenses (excluding provisions for 
possible loan and lease losses, write-downs of other real estate and 
taxes); and provided, further, that material adverse effect and material 
impairment shall not be deemed to include the impact of (x) changes 
in banking and similar laws of general applicability or interpretations 
thereof by courts or governmental authorities, (y) changes in generally 
accepted accounting principles or regulatory accounting requirements 
applicable to banks and bank holding companies generally and (z) the 
effects of Share Exchange on the operating performance of the parties 
to this Plan;

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

        (I)  Entire Understanding.  This Plan represents the entire 
understanding of the parties hereto with reference to the transactions 
contemplated hereby and supersede any and all other oral or written 
agreements heretofore made.  Nothing in this Plan expressed or implied, 
is intended to confer upon any person, other than the parties hereto or 
their respective successors, any rights, remedies, obligations or liabilities 
under or by reason of this Plan, other than as provided in Paragraph (K) below.

        (J)  Benefit Plans.  Upon consummation of the Share Exchange, as soon 
as administratively practicable employees of CB 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, MSBC 
shall cause CB to honor in accordance with their terms as in effect on the date 
hereof, or as amended after the date hereof with the prior written consent of 
MSBC, all employment, severance, consulting and other compensation 
contracts and agreements Previously Disclosed to MSBC and executed in 
writing by both CB on the one hand and any individual current or former 
director, officer or employee thereof on the other hand, copies of which have 
previously been delivered by CB to MSBC.

        (K)  Indemnification.  (1) In the case of MSBC only, it agrees that 
for the six-year period following the Share Exchange Effective Date, it shall 
cause CB and any successor thereto to indemnify and hold harmless any 

                                 A-32
<PAGE>

person who has rights to indemnification from CB to the same extent and 
on the same conditions as such person is entitled to indemnification pursuant 
to CB's Articles of Incorporation as in effect on the date of this Plan, to the 
extent legally permitted to do so, with respect to matters occurring on or 
prior to the Share Exchange Effective Date (regardless of whether a claim 
is asserted in connection therewith on or prior to the Share Exchange 
Effective Date or thereafter).  Without limiting the foregoing, in any 
case in which approval by CB may be required to effectuate any such 
indemnification, MSBC shall cause CB to direct, at the election of the 
party to be indemnified, that the determination of any such approval shall 
be made by independent counsel mutually agreed upon between MSBC 
and the indemnified party.  MSBC shall use its reasonable best efforts to 
provide coverage to the officers and directors of CB 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 CB 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).

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

                                                     Annex 1 to Exhibit A
                        PLAN OF SHARE EXCHANGE


     A.  MainStreet BankGroup Incorporated ("the Acquiring Corporation") 
is a corporation organized and existing under the laws of the Commonwealth 
of Virginia.

     B.  Commerce Bank (the "Acquired Corporation") is a Maryland 
bank organized and existing under the laws of the State of Maryland.

     C.  The Acquiring Corporation and the Acquired Corporation, 
their respective Boards of Directors, and the shareholders of the Acquired 
Corporation have approved a statutory share exchange ("Share Exchange") 
of the common stock, $10.00 par value per share, of the Acquired 
Corporation ("Acquired Corporation Common Stock") for shares of 
the common stock, $5.00 par value per share, of the Acquiring 
Corporation ("Acquiring Corporation Common Stock") by which all 
of the outstanding capital corporate stock of the Acquired Corporation 
as of the Effective Time will be acquired by the Acquiring Corporation.

          1.  Effective Time.  The Share Exchange shall become effective at 
the time when the Articles of Share Exchange as approved by the 
Maryland Commissioner of Financial Regulations are accepted for 
filing by the Maryland Department of Assessments and Taxation (the 
"Effective Time") but in no event before the conditions in Article VI 
of the Agreement and Plan of Share Exchange between the Acquiring 
Corporation and the Acquired Corporation dated as of July 3, 1997 
(the "Agreement") shall have been fulfilled or waiver.

          2.  Manner and Basis of Exchange.  The manner and basis of 
exchanging the shares of the Acquired Corporation Common Stock 
issued and outstanding immediately prior to the Effective Time 
(excluding only the Excluded Shares as hereinafter defined) for 
shares of the Acquiring Corporation Common Stock are as follows:

              (A)  Share Exchange Rights.  In exchange for their shares 
of Acquired Corporation Common Stock, the holders of shares 
of the Acquired Corporation Common Stock outstanding immediately 
prior to the Effective Time (excluding only the Excluded Shares) on and 
after the Effective Time automatically and without any action on the 
part of such holders shall be entitled to receive  (the "Share Exchange 
Rights") that number of shares of the Acquiring Corporation Common 
Stock (including the rights attached thereto) obtained by dividing the 
Negotiated Price per share of the Acquired Corporation Common 
Stock by the average of the average of the bid/asked price per share 

                                 A-36
<PAGE>

for the Acquiring Corporation Common Stock as reported on the National 
Association of Securities Dealers Quotations System National Market 
System ("NASDAQ/NMS) for each of the twenty (20) trading days 
preceding the later to occur of (i) the approval of the Share Exchange 
and the other transactions contemplated by the Agreement by the 
shareholders of the Acquired Corporation; and (ii) the financial 
institution regulatory approvals (but not the statutory waiting periods) 
necessary for the consummation of the Share Exchange and the 
other transactions contemplated by the Agreement, subject to possible 
adjustment as set forth in Paragraph (H) below (the "Exchange Ratio"). 
The Negotiated Price per share of the Acquired Company Common Stock is 
$52.00.

     (B)  Stockholder Rights; Stock Transfers.  As of the Effective 
Time, holders of Acquired Corporation Common Stock shall cease to 
be, and shall have no rights as, stockholders of the Acquired Corporation, 
other than to receive the Share Exchange Rights provided under Paragraph 
(A) above, and the consideration provided in Paragraph (C) below or 
to elect to pursue their statutory dissenters' rights as provided under 
Paragraph (D) below).  After the Effective Time, there shall be no transfers 
on the stock transfer books of the Acquired Corporation of the shares of 
Acquired Corporation Common Stock which were issued and outstanding 
immediately prior to the Effective Time.

     (C)  Fractional Shares.  Notwithstanding any other provision 
hereof, no fractional shares of Acquiring Corporation Common Stock and 
no certificates or scrip therefor, or other evidence of ownership thereof, 
will be issued in the Share Exchange; instead, the Acquiring Corporation 
shall pay to each holder of Acquired Corporation Common Stock who would 
otherwise be entitled to a fractional share an amount in cash determined 
by multiplying such fractional share by the average of the last bid/asked 
price of Acquiring Corporation Common Stock on the last trading day prior to 
the Effective Time, as reported on the NASDAQ/NMS (as reported by 
The Wall Street Journal).  

     (D)  Dissenting Stockholders.  Any holder of shares of Acquired 
Corporation Common Stock who perfects his dissenters' rights of appraisal 
in accordance with and as contemplated by Title 3 Subtitle 2 of the 
Corporations and Associations Article of the Annotated Code of Maryland shall 
be entitled to receive the value of such shares in cash as determined 
pursuant to such provision of law; provided, however, that no such payment 
shall be made to any dissenting stockholder unless and until such dissenting 
stockholder has complied with the applicable provisions of the Maryland 
Corporation Law and duly surrendered the certificate or certificates 
representing the shares for which payment is being made.  In the event that 
a dissenting stockholder of the Acquired Corporation fails to perfect, or 
effectively withdraws or loses, his right to appraisal and of payment for 
his shares, after the Effective Time Acquiring Corporation shall issue and 
deliver the consideration to which such holder of shares of Acquired 
Corporation Common Stock is entitled under this Plan of Share Exchange 

                                  A-37
<PAGE>

(without interest) upon surrender by such holder of the certificate or 
certificates representing shares of Acquired Corporation Common Stock held 
by him.

     (E)  Exchange Procedures.  As promptly as practicable after the Effective 
Time, Acquiring Corporation shall send or cause to be sent to each former 
holder of Acquired Corporation Common Stock of record immediately 
prior to the Effective Time transmittal materials for use in exchanging such 
stockholder's certificates of Acquired Corporation Common Stock (other than 
Excluded Shares) for the consideration set forth in Paragraphs (A) and (C) 
above.  Any fractional share checks which a Acquired Corporation Company 
stockholder shall be entitled to receive in exchange for such stockholder's 
shares of Acquired Corporation Common Stock, and any dividends paid on any 
shares of Purchaser Common Stock that such stockholder shall be entitled to 
receive prior to the delivery to ------------------ (the "Exchange Agent") 
of such stockholder's certificates representing all of such stockholder's 
share of Acquired Corporation Common Stock will be delivered to such 
stockholder only upon delivery to the Exchange Agent of the certificates 
representing all of such shares (or indemnity satisfactory to Acquiring 
Corporation and the Exchange Agent, in their judgment, if any of such 
certificates are lost, stolen or destroyed).  No interest will be paid on 
any such fractional share checks or dividends to which the holder of such 
shares shall be entitled to receive upon such delivery.  After the Effective 
Time, to the extent permitted by law, former stockholders of record of the 
Acquired Corporation shall be entitled to vote at any meeting of holders of 
Acquiring Corporation Common Stock the number of whole shares of Acquiring 
Corporation Common Stock to which their Exchange Rights entitle them, 
regardless of whether such holders have exchanged their Acquired 
Corporation Common Stock for certificates representing Acquiring 
Corporation Common Stock in accordance with the provisions of this Plan of 
Share Exchange.

     (F)  Anti-Dilution Provisions.  In the event Acquiring Corporation 
changes the number of shares of Acquiring Corporation Common Stock 
issued and outstanding prior to the Effective Time as a result of a stock 
split, stock dividend, recapitalization or similar transaction with respect 
to the outstanding Acquiring Corporation Common Stock and the record date 
therefor shall be prior to the Effective Time, the Exchange Ratio shall be 
proportionately adjusted.

     (G)  Excluded Shares. Each of the shares of Acquired Corporation Common 
Stock held by the Acquired Corporation, the Acquiring Corporation or 
any of its subsidiaries, in each case other than in a fiduciary capacity or 
as a result of debts previously contracted shall be canceled and retired at 
the Effective Time.  Such shares together with shares as to which the holder 
has perfected his dissenter's rights of appraisal in accordance with 
Paragraph (D) are "Excluded Shares".

                                  A-38
<PAGE>

     (H)  Possible Adjustment in Exchange Rate.  The Agreement may be 
terminated prior to the Effective Time (i) as set forth in 3 below or (ii) 
either before or after approval by the stockholders of the Acquired 
Corporation, by the Acquired Corporation, by vote of a majority of the 
members of its entire Board during the ten (10) day period commencing on the 
Determination Date if both of the following conditions are satisfied:

               (1)  if the Average MSBC Determination Price for MSBG Common 
                    Stock on the Determination Date is less than $20.75; 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 the 
Acquired Corporation elects to exercise its termination right pursuant to 
clause (ii), it shall give prompt written notice to the Acquiring Corporation 
(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, the Acquiring 
Corporation shall have the option of increasing the consideration to 
be received by the holders of the Acquired Corporation Common Stock 
by adjusting the Exchange Ratio to equal a quotient, the numerator of 
which is $20.75 multiplied by the Exchange Ratio (as then in effect) and the 
denominator of which is the Average MSBC Determination Price.  If 
the Acquiring Corporation makes an election contemplated by the 
immediately preceding sentence, it shall give prompt written notice 
to the Acquired Corporation of such election and the revised Exchange 
Ratio, whereupon no termination shall have accrued pursuant to clause 
(ii) and the Agreement 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 Subparagraph 
(H).  For purposes of this Paragraph (H) the following terms shall 
have the meanings indicated:

        "Average MSBC Determination Price" means the average of the 
bid/asked price for Acquiring Corporation Common Stock 
as reported on the NASDAQ/NMS for the 20 consecutive full trading 
days preceding the Determination Date.

         "Determination Date" means the tenth day prior to the Share 
Exchange Closing.

          "First Percentage" means the percentage resulting from: (a) 
taking the remainder ("First Remainder") obtained by subtracting 
the Average MSBC Determination Price from $23.625 (the average 

                                 A-39
<PAGE>

of the bid and asked prices of Acquiring Corporation Common Stock 
as reported on the NASDAQ/NMS on June 18, 1997; and (b) dividing 
the First Remainder by the Average MSBC Determination 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 
Price ("Recent SNL Bank Index") from the SNL Southeast Bank 
Index at June 18, 1997; and (b) dividing the Second Remainder by 
the Recent SNL Bank Index.

          "Share Exchange Closing" means the date designated as 
such by the Acquiring Corporation and reasonably acceptable to the 
Acquired Corporation after the satisfaction of the conditions to the 
Share Exchange set forth in Paragraphs (A), (B) and (C) of Article 
VI of the Agreement but no later than the Effective Time.

     3.  Termination of Abandonment.  In addition to the termination 
provisions set forth above, this Plan of Share Exchange shall terminate 
and the Share Exchange be abandoned at any time prior to the 
Effective Time if the Agreement is terminated in accordance with its terms.

     4.  Amendment.  Pursuant to 3-105 of the Corporations and 
Associations Article of the Annotated Code of Maryland, the Board 
of Directors of the Acquiring Corporation and the Acquired Corporation 
reserve the right to amend this Plan of Share Exchange at any time prior 
to the acceptance by the Maryland Department of Assessments and 
Taxation of the Articles of Share Exchange for filing; provided, 
however, that any such amendment made subsequent to the submission 
of this Plan of Share Exchange to the shareholders of the Acquired 
Corporation, may not:  (i) alter or change the amount or kind of 
shares, securities, cash, property or rights to be received in exchange 
for or in conversion of all or any of the shares of any class or series 
of such corporation; (ii) alter or change any of the terms and conditions 
of this Plan of Share Exchange if such alteration or change would 
adversely affect the shares of any class or series of such corporation; 
or (iii) alter or change any term of the articles of incorporation of any 
corporation (except as provided herein) whose shareholders must 
approve this Plan of Share Exchange.

MainStreet BankGroup Incorporated
address



Gentlemen:

     Pursuant to the terms of the Agreement and Plan of Share Exchange, 
dated as of July 3, 1997, by and between MainStreet BankGroup 
Incorporated, a Virginia corporation ("MSBG") and Commerce Bank, 
a Maryland bank ("CB"), (the "Agreement") all of the issued and outstanding 
shares of the common stock, $10.00 par value of CB, will be acquired by 
MSBG. As a result of the Share Exchange, the undersigned may receive 
shares of Common Stock, $5.00 par value per share, of MSBG 
("MSBG Common Stock").  The undersigned would receive such shares 
in exchange for shares owned by the undersigned of Common Stock, 
$10.00 par value per share, of CB.

     The undersigned hereby represents, warrants to, and covenants with, 
MSBG that in the event the undersigned receives any MSBG Common 
Stock as a result of the Share Exchange:

          (A)  The undersigned shall not make any sale, transfer or other 
     disposition of the MSBG Common Stock in violation of the Securities 
     Act of 1933, as amended, or the rules and regulations thereunder 
     (the "Act").

          (B)  The undersigned has carefully read this letter and discussed 
     its requirements and other applicable limitations upon the 
     undersigned's ability to sell, transfer or otherwise dispose of MSBG 
     Common Stock to the extent the undersigned felt necessary, with the 
     undersigned's counsel or counsel for CB.

                                 A-41
<PAGE>

          (C)  The undersigned will not sell, transfer or otherwise dispose 
     of MSBG Common Stock issued to the undersigned in the Share 
     Exchange unless (i) such sale, transfer or other disposition has been 
     registered under the Act, (ii) such sale, transfer or other disposition 
     is made in conformity with the provisions of Rule 145 under the Act 
     (as such rule may be hereafter from time to time be amended), or 
     (iii) in the opinion of counsel in form and substance reasonably 
     acceptable to MSBG, in which counsel for MSBG concurs, or in 
     a "no-action" letter obtained by the undersigned from the staff 
     of the Securities and Exchange Commission (the "Commission"), a 
     determination is made that such sale, transfer or other disposition will 
     not violate or is otherwise exempt from registration under the Act.

          (D)  The undersigned understands that MSBG is under no 
     obligation to register the sale, transfer or other disposition of shares 
     of MSBG Common Stock by the undersigned or on the undersigned's 
     behalf under the Act or to take any other action necessary in order to 
     make compliance with an exemption from such registration available.

          (E)  The undersigned also understands that stop transfer 
     instructions will be given to MSBG's transfer agent with respect to 
     MSBG Common Stock owned by the undersigned and that there will 
     be placed on the certificates for the MSBG Common Stock issued to 
     the undersigned, or any substitutions therefor, a legend stating in 
     substance:

               "The shares represented by this certificate were 
          issued in a transaction to which Rule 145(d) under the 
          Securities Act of 1933 applies.  The shares represented 
          by this certificate may only be transferred in accordance 
          with the terms of a letter agreement dated -------------, 
          199--- between the registered holder hereof and MainStreet 
          BankGroup Incorporated, a copy of which agreement is on file 
          at the principal offices of MainStreet BankGroup 
          Incorporated."

          (F)  The undersigned also understands that unless the transfer 
     by the undersigned of the undersigned's MSBG Common Stock has 
     been registered under the Act or is a sale made in conformity with the 
     provisions of Rule 145(d) under the Act, MSBG reserves the right, in 
     its sole discretion, to place the following legend on the certificates 
     issued to any transferee of shares from the undersigned:

               "The shares represented by this certificate have not 
          been registered under the Securities Act of 1933 and were 

                                  A-42
<PAGE>

          acquired from a person who received such shares in a 
          transaction to which Rule 145 under the Securities Act of 
          1933 applies.  The shares have been acquired by the holder 
          not with a view to, or for resale in connection with, any 
          distribution thereof within the meaning of the Securities 
          Act of 1933 and may not be offered, sold, pledged or otherwise 
          transferred except in accordance with an exemption from the 
          registration requirements of the Securities Act of 1933."

          It is understood and agreed that the legends set forth in 
     paragraphs (E) and (F) above shall be removed by delivery of substitute 
     certificates without such legend if the undersigned shall have 
     delivered to MSBG (i) a copy of a "no action" letter from the staff of 
     the Commission, or an opinion of counsel in form and substance 
     reasonably satisfactory to MSBG, in which counsel for MSBG concurs, to 
     the effect that such legend is not required for purposes of the Act, or 
     (ii) reasonably satisfactory evidence or representations that the 
     shares represented by such certificates are being or have been 
     transferred in a transaction made in conformity with the provisions of 
     Rule 145(d).

          (G)  The undersigned further represents and warrants to, and 
     covenants with, MSBG that the undersigned will not, within the 30 days 
     prior to the Share Exchange Effective Date (as defined in this 
     Agreement), sell, transfer or otherwise dispose of any shares of the 
     capital stock of either MSBG or CB held by the undersigned, and that 
     the undersigned will not sell, transfer or otherwise dispose of any 
     shares of MSBG Common Stock received by the undersigned in the Share 
     Exchange or other shares of the capital stock of MSBG until after such 
     time as results covering at least 30 days of combined operations of 
     MSBG after the Share Exchange have been published by MSBG within the 
     meaning of section 201.01 of the Commission's Codification of Financial 
     Reporting Policies.

          (H)  The undersigned also understands and agrees that this letter 
     agreement shall apply to all shares of the capital stock of CB and MSBG 
     that are owned by (i) the undersigned's spouse, (ii) any relative of the 
     undersigned or of the undersigned's spouse who has the same home as 
     the undersigned, (iii) any trust or estate in which the undersigned, the 
     undersigned's spouse, and any such relative collectively own at least a 
     10% beneficial interest or of which any of the foregoing serves as 
     trustee, executor, or in any similar fiduciary capacity, and (iv) any 
     corporation or other organization in which the undersigned, the 
     undersigned's spouse, and any such relative collectively own at least 
     10% of any class of equity securities or of the equity interest, or 

                                 A-43
<PAGE>

     that otherwise are deemed to be beneficially owned by the undersigned 
     pursuant to Rule 13(d) under the Securities Exchange Act of 1934.

                                 Very truly yours,

respects as to form with the provisions of the Federal Securities Laws.  
Further such counsel does not believe that, insofar as they relate to MSBC 
and its subsidiaries, the Registration Statement and Prospectus, on such 
effective date, contained any untrue statement of a material fact or omitted 
to state any material fact required to be stated therein or necessary to make 
the statements therein not misleading.  (Such opinion may state that such 
counsel does not assume any responsibility for the accuracy or fairness of 
the statements contained in the Registration Statement and Prospectus and 
that he does not express any opinion or belief as to material in the 
Registration Statement insofar as it includes or reflects any information 
relating to or supplied by entities other than MSBC or its subsidiaries or

                     AMENDMENT TO AGREEMENT AND PLAN
                          OF SHARE EXCHANGE

        This Amendment ("Amendment") dated as of October 14, 1997, to the
Agreement and Plan of Share Exchange dated as of July 3, 1997 ("Plan") is
entered into by and between MainStreet BankGroup Incorporated, a Virginia
corporation ("MSBC") and Commerce Bank (Commerce Bank Corporation)("CB"), a
Maryland bank.

        Whereas, MSBC and CB entered into the Plan as of July 3, 1997;

        Whereas, MSBC and CB desire to clarify certain provisions of the Plan
relating to the Warrant Redemption Ratio (as defined in the Plan) in order to
insure that the parties' intent with respect thereto is fully and explicitly
set forth in the Plan.

        NOW, THEREFORE, in consideration of these premises, the mutual promises
of the parties and good and valuable consideration, the receipt and sufficiency
of which are hereby acknowledged, the parties hereto agree as follows:

        1.  Definitions.  The terms defined in the Plan when used in this
Amendment shall have the same meaning provided in the Plan except as they may
be expressly defined differently in this Amendment.

        2.  Amedment to Plan.

            (a)  The second sentence of Paragraph (R) of Article VI shall be
                 amended to read in its entirety as follows:

                  "If the Warrant Redemption Ratio computed in accordance
                  with the immediately preceding sentence is less than 1.228,
                  the Warrant Redemption Ratio shall be 1.228 ("Lower
                  Collar"); if the Warrant Redemption Ratio computed in
                  accordance with the immediately preceding sentence is
                  greater than 1.494, the Warrant Redemption Ratio shall be
                  1.494 ("Upper Collar"); provided, however, that if the Warrant
                  Redemption Ratio determined in accordance with the
                  immediately preceding clause equals either the Lower Collar
                  or the Upper Collar, the Warrant Redemption Ratio shall be
                  further adjusted, if necessary, so that shares of MSBC
                  Common Stock to be issued for each CB Warrant pursuant
                  thereto shall be equal in value to the difference obtained by

                               A-53
<PAGE>
                  subtracting $21.00 from the product of the Average MSBC
                  Share Price times the Exchange Ratio (as defined in Article
                  II, Paragraph B).

            (b)  The definition of Plan as used in the Plan shall include the
                 Plan as amended hereby and this Amendment.

        3.  Except as expressly set forth in this Amendment, the terms and
conditions of the Plan are in full force and effect and have not been amended
or modified in any way.  The respective representations and warranties of the
parties as set forth in the Plan are true and correct as of the date of this
Amendment as though made on the date hereof except (a) for any such
representations and warranties made as of a specified date, which shall be true
and correct as of such date, (b) as expressly contemplated by the Plan and (c)
for representations and warranties (other than the representations and
warranties set forth in Paragraph (A) of Article IV of the Plan which shall be
true and correct in all material respects) the inaccuracies of which relate to
matters that individually or in the aggregate do not materially adversely
affect the Share Exchange and the other transactions contemplated by the Plan
and this Amendment.  This Amendment has been authorized by all necessary
corporate action of each party and is a valid and binding agreement of it
enforceable against it in accordance with its terms, subject to (1) bankruptcy,
insolvency and other laws of general applicability relating to or affecting
creditors' rights; and (2) general equity principles.  This Amendment shall
be governed by and interpreted in accordance with the laws of the State of
Virginia and represents the entire understanding of the parties hereto with
reference to the matters set forth herein.  Nothing in this Agreement, express
or implied, is intended to confer upon any person, other than the parties hereto
or their respective successors, any rights, remedies, obligations or liabilities
under or by reason of this Amendment.

        In witness whereof, the parties hereto have executed this Amendment as
of the date and year first written above.

                          September 17, 1997

	

Board of Directors
Commerce Bank
College Park, MD   20740

Gentlemen:
   
     You have asked us to render our opinion relating to the fairness, 
from a financial point of view, to the shareholders of Commerce 
Bank ("Commerce") of the terms of an Agreement and Plan of 
Share Exchange by and between MainStreet BankGroup Incorporated 
("MainStreet") and Commerce dated July 3, 1997 and the Amendment thereto
(the "Share Exchange Agreement").  The Share Exchange Agreement provides
for the acquisition of Commerce by MainStreet through a share exchange 
(the "Share Exchange") and further provides that each share of 
Common Stock (and Preferred Stock) of Commerce which is issued and
outstanding immediately prior to the Effective Date of the Share Exchange
shall be converted (redeemed) into a number of shares of MainStreet
Common Stock equal to the quotient of $52.00 divided by the average of
the bid/ask price per share for MainStreet Common Stock as reported on
the NASDAQ National Market for the 20 trading days preceding the later
to occur of (the "Average MainStreet Share Price") (i) approval of the
Share Exchange by the shareholders of Commerce or (ii) receipt of the
last of all regulatory approvals prerequisite to the consummation of the 
Share Exchange (the "Exchange Ratio"). In no case will the Exchange 
Ratio be less than 2.059 or greater than 2.506. In addition, each 
Commerce Warrant shall be redeemed in return for that number of 
shares of MainStreet Common Stock equal to the quotient obtained by 
dividing $31.00 by the Average MainStreet Share Price (the 
"Warrant Redemption Ratio").  If the Warrant Redemption Ratio computed
in accordance with the immediately preceding sentence is less than
1.228, the Warrant Redemption Ratio shall be 1.228; if the Warrant
Redemption Ratio computed in accordance with the immediately preceding
sentence is greater than 1.494, the Warrant Redemption Ratio shall be
1.494; provided however, that if the Warrant Redemption Ratio computed
equals either the 1.228 or 1.494, the Warrant Redemption Ratio shall be
further adjusted, if necessary, so that shares of MainStreet Common
Stock to be issued for each Commerce Warrant be equal in value to the
difference obtained by subtracting $21.00 from the product of the
Average MainStreet Share Price times the Exchange Ratio.
    
     In developing our opinion, we have, among other things, reviewed 
and analyzed: (1) the Share Exchange Agreement; (2) the Registration 
Statement and this Proxy Statement; (3) Commerce's financial 
statements for the three years ended December 31, 1996; (4) 
Commerce's unaudited financial statements for the quarter ended 
June 30, 1997 and 1996, and other internal information relating to 
Commerce prepared by Commerce's management; (5) information 

                                 B-1
<PAGE>

regarding the trading market for the common stocks of Commerce and 
MainStreet and the price ranges within which the respective stocks have 
traded; (6) the relationship of prices paid to relevant financial data such 
as net worth, assets, deposits and earnings in certain bank and bank 
holding company mergers and acquisitions in Maryland in recent years; 
(7) MainStreet's annual reports to shareholders and its financial statements 
for the three years ended December 31, 1996; and (8) MainStreet's 
unaudited financial statements for the quarter ended June 30, 1997 
and 1996, and other internal information relating to MainStreet prepared 
by MainStreet's management.  We have discussed with members 
of management of Commerce and MainStreet the background to the 
Share Exchange, reasons and basis for the Share Exchange and the 
business and future prospects of Commerce and MainStreet 
individually and as a combined entity.  Finally, we have conducted such 
other studies, analyses and investigations, particularly of the 
banking industry, and considered such other information as we 
deemed appropriate.

     In conducting our review and arriving at our opinion, we have 
relied upon and assumed the accuracy and completeness of the information 
furnished to us by or on behalf of Commerce and MainStreet.  We 
have not attempted independently to verify such information, nor 
have we made any independent appraisal of the assets of Commerce 
or MainStreet.  We have taken into account our assessment of general 
economic, financial market and industry conditions as they exist and 
can be evaluated at the date hereof, as well as our experience in 
business valuation in general.

     On the basis of our analyses and review and in reliance 
on the accuracy and completeness of the information furnished to us 
and subject to the conditions noted above, it is our opinion that, as of 
the date hereof the terms of the Share Exchange Agreement are fair from 
a financial point of view to the shareholders of Commerce Common 
Stock, Preferred Stock and the Warrant holders.

                                 Very truly yours,

                                 SCOTT & STRINGFELLOW, INC.

                 INFORMATION NOT REQUIRED IN PROSPECTUS

Item 20.  Indemnification of Officers and Directors

     Registrant's Articles of Incorporation implement the provisions of the 
VSCA, which provide for the indemnification of Registrant's directors and 
officers in a variety of circumstances, which may include indemnification for 
liabilities under the Securities Act of 1933.  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.  Registrant's Articles of 
Incorporation require indemnification of directors and officers with respect 
to certain liabilities, expenses and other amounts imposed upon them by 
reason of having been a director or officer, except in the case of willful 
misconduct or a knowing violation of criminal law.  Registrant also carries 
insurance on behalf of directors, officers, employees or agents that may 
cover liabilities under the Securities Act of 1933.  In addition, the VSCA 
and Registrant's Articles of Incorporation eliminate the liability of a 
director or officer of Registrant 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.

Item 22.  Undertakings

       (a)   The undersigned Registrant hereby undertakes as follows:

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

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

                                 II-2
<PAGE>

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

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

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

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

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

     4        That prior to any public reoffering of the securities registered 
              hereunder through the use of a prospectus which is a part of this 
              registration statement, by any person or party who is deemed to 
              be an underwriter within the meaning of Rule 145(c), the 

                                 II-3
<PAGE>

              Registrant undertakes that such reoffering prospectus will 
              contain the information called for by the applicable 
              registration form with respect to reofferings by persons who 
              may be deemed underwriters, in addition to the information 
              called for by the other items of the applicable form.

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

     6        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.

                                 II-4

     (b)      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.

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

                              SIGNATURES
