                       PENINSULA TRUST BANK, INCORPORATED
                                       AND
                     MID-ATLANTIC COMMUNITY BANKGROUP, INC.



         This  Agreement and Plan of Share  Exchange  ("Agreement")  is made and
entered  into as of  February  29,  1996 by and  between  PENINSULA  TRUST BANK,
INCORPORATED,  a Virginia state bank (the "Bank"),  and  MID-ATLANTIC  COMMUNITY
BANKGROUP, INC., a Virginia corporation (the "Corporation").

                                    RECITALS

         1.        The Board of Directors of the Bank has determined that it is
in the  best  interests  of the  Bank  and its  shareholders  for the Bank to be
reorganized into the holding company form of ownership;

         2.       The Bank has caused the Corporation to be organized under 
Virginia  law as a wholly  owned  subsidiary  for the  purpose of  becoming  the
holding company of the Bank; and

         3.       The  reorganization  will be  effected  by a share  exchange 
under  Virginia law in which each share of common stock of the Bank is exchanged
for one share of common stock of the Corporation:

         NOW,  THEREFORE,  the  Bank  and the  Corporation  do  hereby  agree as
follows:







         1.       The Share Exchange.  Subject to the terms and conditions 
hereof,  the Bank shall  become a  wholly-owned  subsidiary  of the  Corporation
through the exchange of each  outstanding  share of common stock of the Bank for
one share of the common stock of the Corporation in accordance with Section 3 of
this  Agreement in a statutory  share  exchange  under  Section  13.1-717 of the
Virginia Stock  Corporation Act (the "Share  Exchange").  At the Effective Date,
the Share  Exchange  shall have the  effects  stated in Section  13.1-721 of the
Virginia Stock Corporation Act.

         2.       Articles of Incorporation and Bylaws.  The Articles of 
Incorporation  and Bylaws of the Corporation in effect  immediately prior to the
consummation  of the  Share  Exchange  shall  remain  in  effect  following  the
Effective Date until amended or repealed.

         3.        Exchange of Shares.  On the date specified in a Certificate 
of Share  Exchange  issued by the  Virginia  State  Corporation  Commission  and
relating to this Agreement (the "Effective Date"):

                  (a)      Each share of common stock, par value $5.00 per 
share,  of the Bank ("Bank Common  Stock")  issued and  outstanding  immediately
prior to the  Effective  Date  shall,  by  operation  of law,  be  automatically
exchanged for one share of Corporation  Common Stock,  par value $5.00 per share
("Corporation Common Stock"); and


                                        2





                  (b)      The Corporation shall become the owner and holder of
all the shares of Bank Common Stock issued and outstanding.

         4.       Manner of Exchange.  Each holder of a certificate representing
any shares of Bank Common  Stock upon the  surrender  of his Bank  Common  Stock
certificates to the  Corporation,  duly endorsed for transfer in accordance with
this Section 4, will be entitled to receive in exchange  therefor a  certificate
or certificates  representing  the number of shares of Corporation  Common Stock
for which his shares of Bank  Common  Stock are  exchanged  pursuant  to Section
3(a).

                  As promptly as practicable after the Effective Date, the Bank,
acting as the Corporation's exchange agent ("Exchange Agent") shall send to each
person  who is a  shareholder  of  record of the Bank  immediately  prior to the
Effective Date  transmittal  materials for use in exchanging such  shareholder's
certificates  of Bank Common Stock (other than shares held by  stockholders  who
perfect  their  dissenters'  rights as provided  under Section 7 hereof) for the
consideration set forth in Section 3(a) above.

         5.       Dividends.  No dividend or other distribution payable to the 
holders  of record of  Corporation  Common  Stock at or as of any time after the
Effective  Date  shall be paid to the  holder  of any  certificate  representing
shares of Bank Common Stock issued and  outstanding  at the Effective Date until
such holder physically surrenders such certificate for

                                        3





exchange as provided in Section 4 of this  Agreement,  promptly after which time
all such dividends or distributions shall be paid (without interest).

         6.       Employee and Director Stock Plans.  At the Effective Date, al
stock option and stock-based  compensation  plans of the Bank (the "Bank Plans")
shall  automatically  be  continued  as and  become  plans  of  the  Corporation
("Corporation Plans"). At the Effective Date, there shall be substituted for the
options  granted  under  the Bank  Plans  ("Old  Options"),  new  options  ("New
Options")  under  the  Corporation  Plans  without  any  action  on the  part of
optionees,  and  each New  Option  shall be for the same  number  of  shares  of
Corporation Common Stock,  exercisable at the same price and subject to the same
terms and  conditions  as each Old Option was with respect to Bank Common Stock.
The substitution of New Options for Old Options shall be done in accordance with
the provisions of Section 425(a) of the Internal Revenue Code of 1986. Under the
Corporation   Plans,  the  Corporation  shall  assume  all  of  the  rights  and
obligations of Bank under the Bank Plans.

         At the Effective Date, the Board of Directors of the Corporation  shall
be deemed to have reserved and  authorized  the issuance of the number of shares
of  Corporation  Common Stock under the  Corporation  Plans that is equal to the
number of shares of Bank Common Stock approved by the  shareholders  of Bank for
issuance  under the Bank  Plans  that Bank has not  issued  under the Bank Plans
prior to the Effective Date.


                                        4





         At the  Effective  Date,  all rights to purchase,  sell or receive Bank
Common  Stock and all rights to elect to make payment in Bank Common Stock under
any  agreement  between Bank and any  director,  officer or employee  thereof or
under any plan or program of Bank shall  automatically,  by operation of law, be
converted into and shall become an identical right to purchase,  sell or receive
Corporation  Common Stock and an identical  right to make payment in Corporation
Common Stock under any such agreement between Bank and any director,  officer or
employee thereof or under such plan or program of the Bank.

         7.       Rights of Dissenting Shareholders.  Shareholders of the Bank 
who object to the Share Exchange will be entitled to the rights and remedies set
forth in Sections  13.1-729 through  13.1-741 of the Virginia Stock  Corporation
Act.

         8.       Conditions to the Share Exchange.  The Share Exchange shall 
not be consummated unless the following conditions have been satisfied:

                  (a)      Holders  of the  issued  and  outstanding  shares of
Bank Common Stock shall have approved this Agreement in accordance with Virginia
law and the  Articles  of  Incorporation  of the Bank and the Bank,  as the sole
shareholder of the Corporation, shall have approved this Agreement. None of such
approvals shall have been revoked at or prior to the Effective Time.

                  (b)      If, in the  opinion of counsel  to the  Corporation,
such registration is required,  the Corporation Common Stock to be issued to the
holders of Bank Common Stock pursuant to the Share Exchange shall have been duly
registered  pursuant  to  Section  5 of the  Securities  Act of  1933  and  such
registration  shall not be  suspended at the  Effective  Time.  Further,  to the
extent  required  in the  opinion  of legal  counsel  for the  Corporation,  the
Corporation shall have complied with all applicable securities law of states and
other jurisdictions relating to such issuance of the Corporation Common Stock.

                  (c)      Any and all approvals or consents shall have been 
obtained from the Virginia State Corporation Commission,  the Board of Governors
of  the  Federal  Reserve  System  and  any  other  governmental  agency  having
jurisdiction,  and from other  third  parties  that are, in the opinion of legal
counsel for the Bank or the Corporation, required for the lawful consummation of
the Share Exchange and the issuance and delivery of Corporation  Common Stock as
contemplated by this Agreement and such approvals or consents and shall not have
been revoked.

                  (d)      The Bank shall have received either (i) a ruling fro
the Internal Revenue  Service,  acceptable in form and substance to the Bank and
its legal  counsel,  or (ii) an  opinion  from  Williams,  Mullen,  Christian  &
Dobbins, in either case to the effect that:

                           (1)      The Share Exchange either will constitute 
(i) a  reorganization  under Section  368(a)(1) of the Internal  Revenue Code of
1986, as amended (the "Code") and
                                                   
                                        6





that  the  Bank  and  the  Corporation  each  will  qualify  as  a  "party  to a
reorganization"  within  the  meaning  of  Section  368(b) of the Code or (ii) a
transaction described in Section 351 of the Code;

                           (2)      No  gain  or  loss will be recognized by the
         shareholders  of the Bank upon the  exchange of their Bank Common Stock
         solely for Corporation Common Stock;

                           (3)      No gain or loss will be  recognized  by the
         Corporation  upon its  receipt of Bank  Common  Stock in  exchange  for
         Corporation Common Stock in connection with the Share Exchange;

                           (4)      The aggregate basis of the Corporation 
         Common Stock received by each shareholder of the Bank in the Share
         Exchange will, in each instance,  be the same as the aggregate basis of
         the Bank Common Stock surrendered in exchange therefor; and

                           (5)      The holding period of the Corporation Common
         Stock  received by each  shareholder  of the Bank in the Share Exchange
         will  include the period  during  which the  shareholder  held his Bank
         Common Stock exchanged  therefor,  provided that such Bank Common Stock
         is held as a capital asset on the date of the Share Exchange.

                                        7






                  (e)      Should any shareholders of the Bank dissent pursuant
         to Virginia law, the payments to dissenting shareholders shall not 
         cause the Bank to become undercapitalized or exceed the amount of 
         dividends permissible for the Bank under applicable state and federal 
         law.

         9.       Abandonment  of Agreement.  This  Agreement may be abandoned 
by the Bank or the  Corporation  at any time  before the  Effective  Date in the
event that (a) any action, suit,  proceeding or claim has been instituted,  made

transactions  contemplated  hereby inadvisable in the opinion of the Bank or the
Corporation  or (b)  for  any  other  reason  consummation  of the  transactions
contemplated   hereby  is  inadvisable  in  the  opinion  of  the  Bank  or  the
Corporation. Such abandonment shall be effected by written notice by the Bank or
the  Corporation to the other Party hereto,  authorized or approved by the Board
of Directors  of the Party  giving such notice.  Upon the giving of such notice,
