      E. Directors. The number of directors constituting the initial Board
of Directors is one (1) and set forth below are the name and address of the
person who is to serve as the initial director until the first annual meeting
of the shareholders or until his successor shall be duly elected and qualify:

                           Douglas J. Stanard
                           8100 AMF Drive

the Corporation or by or on behalf of shareholders of the Corporation, the
damages assessed against an officer or director arising out of a single
transaction, occurrence, or course of conduct shall not

<PAGE>

exceed one dollar, unless the officer or director engaged in willful
misconduct or a knowing violation of the criminal law or any federal or
state securities law, including without limitation, any claim of unlawful
insider trading or manipulation of the market for any security.

        G. Indemnification of Directors, Officers and Others.

        1. Indemnification. The Corporation shall indemnify an individual who
is, was or is threatened to be made a party to a proceeding (including a
proceeding by or in the right of the Corporation) because he is or was a
director against liability incurred in the proceeding and against expenses
incurred by him in connection therewith except such liabilities and expenses
incurred because of his willful misconduct or knowing violation of the criminal
law.

        2. Advance for Expenses. The Corporation shall pay for or reimburse the
reasonable expenses incurred by a director who is a party to a proceeding in
advance of final disposition of the proceeding if:

        (a) the director furnishes the Corporation a written statement of
his good faith belief that he has met the standard of conduct described in
Section 1;

        (b) the director furnishes the Corporation a written undertaking,
executed personally or on his behalf, to repay the advance if it is ultimately
determined that he did not meet the standard of conduct (which undertaking
shall be an unlimited general obligation of the director but need not be
secured and may be accepted without reference to financial ability to make
repayment); and

        (c) a determination is made that the facts then known to those
making the determination would not preclude indemnification under Article 10
of the Virginia Stock Corporation Act or Section 1 hereof.

        3. Determination and Authorization of Indemnification. The Corporation
shall not indemnify a director under Section 1 unless authorized in the
specific case after a determination has been made that indemnification of the
director is permissible in the circumstances because he has met the
standard of conduct set forth in Section 1. The determination shall be made:

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

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

        (c) by special legal counsel:

                (i) selected by the Board of Directors or its committee in
the manner prescribed in subsection (a) or (b) above;

                (ii) if such a quorum of the Board of Directors cannot be
obtained and such a committee cannot be designated, selected by a majority vote
of the full Board of Directors, in which directors who are parties may
participate in such selection; or

<PAGE>

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

        Authorization of indemnification and evaluation as to reasonableness
of expenses shall be made in the same manner as the determination that
indemnification is permissible, except that if the determination is made by
special legal counsel, authorization of indemnification and evaluation as to
reasonableness of expenses shall be made by those entitled under
subsection (c) of this Section 3 to select counsel.

        If a majority of the directors of the Corporation has changed after the
date of the alleged conduct giving rise to a claim for indemnification, the
determination that indemnification is permissible and the authorization of
indemnification and evaluation as to the reasonableness of expenses in a
specific case shall, at the option of the person claiming indemnification, be
made by special legal counsel agreed upon by the Board of Directors and such
person.

        4. Indemnification of Officers, Employees, Agents and Others.
Each officer and employee of the Corporation shall be entitled to
indemnification and advance expenses to the same extent as a director.

        The Corporation may, to a lesser extent or to the same extent that
the Corporation is required to provide indemnification and make advances for
expenses to its directors, provide indemnification and make advances and
reimbursements for expenses to its agents, the directors, officers,
employees and agents of its subsidiaries and predecessor entities, and
any person serving any other legal entity in any capacity at the request
of the Corporation, and may contract in advance to do so. The determination
that indemnification under this paragraph is permissible, the authorization
of such indemnification and the evaluation as to the reasonableness of
expenses in a specific case shall be made as authorized from time to time
by general or specific action of the Board of Directors, which action may
be taken before or after a claim for indemnification is made, or as otherwise
provided by law.

        5. Insurance. The Corporation may purchase and maintain insurance
on behalf of an individual who is or was a director, officer, employee or agent
of the Corporation, or who, while a director, officer, employee or agent of
the Corporation, is or was serving at the request of the Corporation as a
director, officer, partner, trustee, employee or agent of another foreign or
domestic corporation, partnership, joint venture, trust, employee benefit
plan or other enterprise, against liability asserted against or incurred by
him in that capacity or arising from his status as a director, officer,
employee or agent, whether or not the Corporation would have power to
indemnify him against the same liability under Section 1.

        6. Application. Indemnity hereunder shall continue as to a person who
has ceased to have the capacity referred to above and shall inure to the
benefit of the heirs, executors and administrators of such a person.
