advance notice as set forth in Section 1.6 of these Bylaws.

C.    The
Board of Directors may designate any place, either within or without the Commonwealth of Virginia, as the place of meeting for any annual meeting or for any special
meeting. If no place is designated by the Board, the place of meeting shall be the principal office of the Corporation.

meeting or special meeting shall be mailed to each Shareholder of record entitled to vote at the meeting at his address as it appears on the records of the Corporation not less than ten
(10) nor more than sixty (60) days before the date of such meeting (except as a different time may be specified by law).

Section 1.4Quorum.    A majority of the votes entitled to be cast on a matter

Section 1.5Voting.    Except as the Articles of Incorporation otherwise
provide, at any meeting of the shareholders, each outstanding share, regardless of class, is entitled to one vote on each matter voted on at a shareholders' meeting.

Section 1.6Notice of Shareholder Business.    (a) At an annual meeting
of the shareholders of the Corporation, only such business shall be concluded as shall have been properly brought before the meeting. To be brought before an annual meeting, business must be
(a) specified in the notice of meeting (or any supplement thereto) given by or at the direction of the Board of Directors, or (c) otherwise properly brought before the meeting by a
shareholder. For business to be properly brought before an annual meeting by a shareholder, the Shareholder must have given timely notice thereof in writing to the Secretary of the Corporation. To be
timely, a shareholder's notice must be delivered to or mailed and received at the principal executive offices of the Corporation, not less than sixty (60) days nor more than ninety
(90) days prior to the date of the scheduled annual meeting, regardless of any postponements, deferrals or adjournments of that meeting to a later date; provided, however, that in the event
that less than seventy (70) days' notice or prior public disclosure of the date of the scheduled annual meeting is given or made, notice by a shareholder, to be timely, must be so received not
later than the close of business on the tenth (10th) day following the earlier of the day on which such notice of the date of the scheduled annual meeting was mailed or the day on which
such

public disclosure was made. A shareholder's notice to the Secretary of the Corporation shall set forth as to each matter the shareholder proposes to bring before the annual meeting (a) a brief
description of
the business desired to be brought before the annual meeting and the reasons for conducting such business at the annual meeting, (b) the name and address, as they appear on the Corporation's
books of the shareholder proposing such business and of any other person or entity who is the record or beneficial owner of any shares of the Corporation and who, to the knowledge of the shareholder
proposing such business, supports such proposal, (c) the class and number of shares of the Corporation which are beneficially owned and owned of record by the shareholder proposing such
business on the date of his notice to the Corporation and the number of shares so owned by any person or entity who, to the knowledge of the shareholder proposing such business, supports such proposal
and (d) any material interest (financial or other) of such shareholder in such proposal. Notwithstanding anything in these Bylaws to the contrary, no business shall be conducted at any annual
meeting except in accordance with the procedures set forth in this Section 1.6. The Chairman of an annual meeting shall, if the facts warrant, determine and declare to the meeting that business
was not properly brought before the meeting and in accordance with the provisions of this Section 1.6. and if he should so determine, he shall so declare to the meeting and any such business
not properly brought before the meeting shall not be transacted.

in Section 1.6(a) shall be interpreted to mean that a shareholder shall not be permitted to ask pertinent questions or to express his or her views on any
pertinent matter.

Section 1.7Order of Business.    All meetings of shareholders shall be
concluded in accordance with such rules as are prescribed by the Chairman of the meeting and he shall determine the order of business at all meetings of the shareholders.

Section 1.8Inspectors.    The Board of Directors, in advance of any meeting of
shareholders, may, but shall not be required to, appoint one or more inspectors to act at such meeting or any adjournment thereof. If any of the inspectors so appointed shall fail to appear or act,
the Chairman of the meeting may appoint one or more inspectors. The inspectors shall determine the number of shares of capital stock of the Corporation outstanding and the voting power of each, the
number of shares represented at the meeting, the existence of a quorum, the validity and effect of proxies, and shall receive votes, ballots or consents, hear and determine all challenges and
questions arising in connection with the right to vote, count and tabulate all votes, ballots or consents, determine the results, and do such acts as are proper to conduct the election or vote with
fairness to all shareholders. On request of the Chairman of the meeting, the inspectors shall make a report of any challenge, request or matter determined by them and shall execute a certificate of
any fact found by them. No director or candidate for the office of director shall act as an inspector of an election of directors. Inspectors need not be shareholders.

ARTICLE II

Section 2.1General Powers.    The business and affairs of the Corporation
shall be managed under the direction of the Board of Directors and, except as otherwise expressly provided by law or by the
Articles of Incorporation, or by these Bylaws, all of the powers of the Corporation shall be exercised by or under the authority of said Board of Directors.

Section 2.2Number and Qualification.    The Board of Directors shall consist
of sixteen directors, provided that a vacancy on the Board of Directors shall not prevent the Board of Directors from acting.

As
more particularly described in the Articles of Incorporation, the directors shall be divided into three classes (A, B and C) as nearly equal in number as possible. The initial
term of office for members of Class A shall expire at the first annual meeting of stockholders after their election; the initial term of office for members of Class B shall expire at the
second annual meeting of stockholders after their election; and the initial term of office for members of Class C shall expire at the third

annual meeting of stockholders after their election. At each annual meeting of stockholders following such initial classification and election, directors elected to succeed those directors whose
terms expire shall be elected for a term of office to expire at the third succeeding annual meeting of stockholders after their election, and shall continue to hold office until their respective
successors are elected and qualify.

In
the event of any increase or decrease in the number of directors fixed by the Bylaws, all classes of directors shall be increased or decreased as equally as may be possible.
Newly-created directorships resulting from an increase by not more than two in the authorized number of directors or any vacancies in the Board of Directors resulting from death, resignation,
retirement, disqualification, removal from office, or other cause, shall be filled by the affirmative vote of a majority of the directors then in office, whether or not a quorum. Each director so
chosen shall hold office until the expiration of the term of the director, if any, whom he has been chosen to succeed or, if none, until the expiration of the term of the class assigned to the
additional directorship to which he has been elected, or until his earlier death, resignation or removal. 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 from office at any time but only for cause and only by the affirmative vote of the holders of more than
two-thirds of each class of the voting stock of the Corporation then outstanding at a meeting called for that purpose.

Section 2.3Election of Directors.    The Directors shall be elected at the
annual meeting of shareholders, and shall hold their offices until their successors are elected in accordance with the Articles of Incorporation. Nominations for the election of Directors shall be
given in the manner provided in Section 2.5. At the annual meeting of shareholders in 2001, Harold E. Lieding, or an individual designated by Directors who formerly were directors of Heritage
Bancorp, Inc., shall be nominated for election to a three-year term. At the annual meeting of shareholders in 2002, Kevin B. Tighe, or an individual designed by Directors who
formerly were directors of Heritage Bancorp, Inc., shall be nominated for election to a three-year term. At the annual meeting of shareholders in 2003, George P. Shafran or an
individual designated by Directors who were formerly directors of Heritage Bancorp, Inc. shall be nominated for election to a three-year term. If the seat held by any of
Messrs. Lieding, Tighe or Shafran becomes vacant, the Board shall appoint a successor chosen by the Directors who formerly
were directors of Heritage Bancorp, Inc. Prior to the annual meeting of shareholders in 2003, this Section 2.3 may be amended only by the unanimous vote of the entire Board of Directors.

Section 2.4Honorary and Advisory Directors.    The Board may appoint to the
position of Honorary Director or the position of Advisory Director such person or persons as it deems appropriate. Honorary Directors shall be entitled to receive notice of, and to attend all meetings
of the Board, but they shall not be Directors and shall not be entitled to vote, nor shall they be counted in determining a quorum of the Board. Advisory Directors shall be entitled only to notice of
meetings of Advisory or other Boards of the Corporation to which they shall be appointed. Honorary and Advisory Directors shall receive such compensation as may be authorized by the Board of
attendance at meetings of Advisory or other Board to which such Advisory or Honorary Directors are appointed.

the procedures set forth in this Section 2.5 shall be eligible for election as Directors. Nominations of persons for election to the Board of Directors of the Corporation may be made by or at

Section 2.5(a). Such nominations, other than those made by or at the direction of the Board of Directors, shall be made pursuant to timely notice in writing to the Secretary of the Corporation.
To be timely, a shareholder's notice shall be delivered to or mailed and received at the principal executive offices of the Corporation not less than sixty (60) days nor more than ninety

the meeting is given or made, notice by the shareholder to be timely must be so received not later than the close of business on the 10th day following the earlier of the day on which
such notice of the date of the scheduled annual meeting was mailed or the day on which such public disclosure was made. Such shareholder's notice shall set forth (a) as to each person whom the
shareholder proposes to nominate for election as a Director, (i) the name, age, business address and residence address of such person, (ii) the principal occupation or employment of such
person, (iii) the class and number of shares of the Corporation which are beneficially owned by such person and (iv) any other information relating to such person that is required to be
disclosed in solicitations of proxies for election of Directors, or is otherwise required, in each case pursuant to Regulation 14A under the Securities Exchange Act of 1934, as amended; and

accordance with the procedures set forth in this Section 2.5(a). The Chairman of the meeting shall, if the facts warrant, determine and declare to the meeting that a nomination was not made in
