         OLD DOMINION SYSTEMS, INC., a corporation organized and existing under
     the laws of the Commonwealth of Virginia (the "Corporation"), desiring to
     amend and restate its Articles of Incorporation, does hereby certify as
     follows:

         1. The Board of Directors of the Corporation, at a meeting duly held on
     March 18, 1986, adopted resolutions recommending the adoption of the
     proposed Amended and Restated Articles of Incorporation, which read in
     their entirety as set forth in Exhibit A; recommending a three for one
     stock split in the form of a 200% stock dividend of its outstanding shares
     of common stock, par value $.01 per share; and directing that such Amended
     and Restated Articles of Incorporation and proposed stock split be
     submitted to a vote of the shareholders.

         2. Written waivers of notice of the meeting of the shareholders to act
     upon the proposed Amended and Restated Articles of Incorporation and stock
     split were received by the Secretary of the Corporation from each
     shareholder of record entitled to vote on the proposed Amended and Restated
     Articles of Incorporation and stock split. Such waivers waived notice of
     the place, day and hour of the meeting and the purpose or purposes for
     which the meeting was called, such purposes including consideration of the
     proposed Amended and Restated Articles of Incorporation and stock split,
     and waived prior receipt of a copy of the proposed Amended and Restated
     Articles of Incorporation.

     a three for one stock split shall occur in the form of a 200% stock

                           OLD DOMINION SYSTEMS, INC.

         Article 1. Corporate Name. The name of the corporation is Old Dominion
     Systems, Inc. (hereinafter called the "Corporation").

         Article 2. Duration. The duration of the Corporation is perpetual.

         Article 3. Purposes. The purpose or purposes for which the Corporation
     is organized are to transact any or all lawful business, not required to be
     specifically stated in the Articles of Incorporation, for which
     corporations may be incorporated under the Virginia Stock Corporation Act.

         Article 4. Capital Stock. The aggregate number of shares of all classes
     of the capital stock which the Corporation shall have authority to issue is
     eleven million (11,000,000), of which ten million (10,000,000) shall be
     common stock, par value $.01 per share, and one million (1,000,000) shall
     be serial preferred stock, par value $.01 per share. The board of directors
     of the Corporation may determine the times when, the terms under which and
     the consideration for which the Corporation shall issue, dispose of or
     receive subscriptions for its shares, including treasury shares, or acquire
     its own shares. The consideration for the issuance of the shares shall be
     paid in full before their issuance and shall not be less than the par value
     per share. Upon payment of such consideration, such shares shall be deemed
     to be fully paid and nonassessable by the Corporation.

         A description of the different classes and series of the Corporation's
     capital stock and a statement of the powers, designations, preferences,
     limitations and relative rights of the shares of each class of and series
     of capital stock are as follows:

         A. Common Stock. Except as provided in this Article 4 (or in any
     resolution or resolutions adopted by the board of directors pursuant
     hereto), the holders of the common stock shall exclusively possess all
     voting power. Each holder of shares of common stock shall be entitled to
     one vote for each share held by such holder. There shall be no cumulative
     voting rights in the election of directors. Each share of common stock
     shall have the same relative rights as and be identical in all respects
     with all other shares of common stock.

         Whenever there shall have been paid, or declared and set aside for
     payment, to the holders of the outstanding shares of any class of stock
     having preference over the common stock as to the payment of dividends, the
     full amount of dividends and of sinking fund or retirement fund or other
     retirement payments, if any, to which such holders are respectively
     entitled in preference to the common stock, then dividends may be paid on
     the common stock and on any class or series of stock entitled to
     participate therewith as to dividends, out of any assets legally available
     for the payment of dividends; but only when and as declared by the board of
     directors.

         In the event of any liquidation, dissolution or winding up of the
     Corporation, after there shall have been paid to or set aside for the
     holders of any class having preferences over the common stock in the event
     of liquidation, dissolution or winding up of the full preferential amounts
     of which they are respectively entitled, the holders of the common stock,
     and of any class or series of stock entitled to participate therewith, in
     whole or in part, as to distribution of assets, shall be entitled after
     payment or provision for payment of all debts and liabilities of the
     Corporation, to receive the remaining assets of the Corporation available
     for distribution, in cash or in kind.

         B. Serial Preferred Stock. The board of directors of the Corporation is
     authorized, subject to limitations prescribed by law and the provisions of
     this Article 4, to provide by resolution for the issuance of serial
     preferred stock in series, including convertible preferred stock, and by
     filing a certificate pursuant to the applicable law of the Commonwealth of
     Virginia, to establish from time to time the number of shares to be
     included in each such series, and to fix the designations, powers,
     preferences and relative, participating, optional and other special rights
     of the shares of each such series and the qualifications, limitations or
     restrictions thereof.

<PAGE>

         The authority of the board of directors with respect to each series
     shall include, but not be limited to, determination of the following:

                  (a)The number of shares constituting that series and the
                  distinctive designation of that series;

                  (b) The dividend rate on the shares of that series, whether
                  dividends shall be cumulative, and, if so, from which date or
                  dates, and the relative rights of priority, if any, of payment
                  of dividends on shares of that series;

                  (c) Whether that series shall have voting rights, in addition
                  to the voting rights provided by law, and, if so, the terms of
                  such voting rights;

                  (d) Whether that series shall have conversion privileges, and,
                  if so, the terms and conditions of such conversion, including
                  provision for adjustment of the conversion rate in such events
                  as the board of directors shall determine;

                  (e) Whether or not the shares of that series shall be

                  (f) Whether that series shall have a sinking fund for the
                  redemption or purchase of shares of that series, and, if so,
                  the terms and amounts of such sinking fund;

                  (g) The rights of the shares of that series in the event of
                  voluntary or involuntary liquidation, dissolution, or winding
                  up of the Corporation, and the relative rights of priority, if
                  any, of payment of shares of that series;

                  (h) Any other relative rights, preferences, and limitations of
                  that series.

         Article 5. Preemptive Rights. No shareholder of the Corporation shall
     have any preemptive rights to purchase, subscribe for or otherwise acquire
     any stock or other securities of the Corporation, whether now or hereafter
     authorized, and any and all preemptive rights are hereby denied.

         Article 6. Directors. The Corporation shall be under the direction of a
     board of directors. The board of directors shall consist of not less than
     three directors nor more than 15 directors. The number of directors within
     this range shall be as stated in the Corporation's by-laws, as may be
     amended from time to time. The board of directors shall divide the
     directors into three classes and, when the number of directors is changed,
     shall determine the class or classes to which the increased or decreased
     number of directors shall be apportioned; provided, that the directors in
     each class shall be as nearly equal in number as possible; provided,
     further, that no decrease in the number of directors shall affect the term
     of any director then in office.

         The classification shall be such that the term of one class shall
     expire each succeeding year. The Corporation's board of directors shall
     initially be divided into three classes named Class I, Class II and Class
     III, with Class I initially consisting of one director and Class II and
     Class III each initially consisting of two directors. The terms,
     classifications, qualifications and election of the board of directors and
     the filling of vacancies thereon shall be as provided herein and in the
     Bylaws. The names of those persons of each class to serve on the board of
     directors shall be as follows:

         Subject to the foregoing, at each annual meeting of shareholders the
     successors to the class of directors whose term shall then expire shall be
     elected to hold office for a term expiring at the third succeeding annual
     meeting and until their successors shall be elected and qualified.

         Any vacancy occurring in the board of directors, including any vacancy
     created by reason of an increase in the number of directors, shall be
     filled for the unexpired term by the concurring vote of a majority of the
     directors then in office, whether or not a quorum, and any director so
     chosen shall hold office for the remainder of the full term of the class of
     directors in which the new directorship was created or the vacancy occurred
     and until such director's successor shall have been elected and qualified.

         Any director may be removed with or without cause by an affirmative
     vote of at least two-thirds of the total votes eligible to be cast by
     shareholders at a duly constituted meeting of shareholders called expressly
     for that purpose; provided, however, that if there are at the time one or
     more Interested Shareholders (as defined in Article 9 hereof), directors
     may only be removed with cause and in addition to such two-thirds vote,
     there must also be an affirmative vote for removal of not less than a
     majority of the voting power of the issued and outstanding shares entitled
     to vote thereon held by shareholders other than such Interested
     Shareholders. At least 30, but not more than 60, days prior to such meeting
     of shareholders, written notice shall be sent to the director or directors
     whose removal will be considered at such meeting.

         Article 7. By-Laws. The board of directors shall have the power to
     amend from time to time the bylaws of the Corporation. Such action by the
     board of directors shall require the affirmative vote of at least a
     majority of the directors then in office at a duly constituted meeting of
     the board of directors called for such purpose. The shareholders may amend
     bylaws made by the board of directors. Such action by the shareholders
     shall require the affirmative vote of at least two-thirds of the total
     votes cast at a duly constituted meeting of shareholders called for such
     purpose; provided, however, that if there are at the time one or more
     Interested Shareholders (as defined in Article 8 hereof), in addition to
     such two-thirds vote, there must also be an affirmative vote for such
     action of not less than a majority of the voting power of the issued and
     outstanding shares entitled to vote thereon held by shareholders other than
     such Interested Shareholders.

         Article 8. Certain Business Combinations.

         involved in the Business Combination or any Affiliate or Associate of
         such Interested Shareholder. Such affirmative vote shall be required
         notwithstanding the fact that no vote may be required, or that a lesser

     Combination" as used in this Article 8 shall mean any transaction which is
     referred to in any one or more of clauses (i) through (v) of paragraph A of

         Subsection 2. When Higher Vote is Not Required.

         The provisions of subsection 1 of this Article 8 shall not be

     Shareholder, whichever is higher; or

                  (b) the Market Valve per share of common stock of the same

     common stock of the same class or series determined pursuant to subdivision
     (i)(b) hereof, multiplied by the ratio of (1) the highest per share price
     (including brokerage commissions, transfer taxes and soliciting dealer's
     fees) paid by the Interested Shareholder for any shares of common stock of
     the same class or series acquired by it within the two-year period
     immediately prior to the Announcement Date, over (2) the Market Value per
     share of common stock of the same class or series on the first day in such
     two-year period on which the Interested Shareholder acquired shares of
     common stock.

<PAGE>

               (ii) The aggregate amount of the cash and the Market Value as of
     the Valuation Date of non-cash consideration to be received per share by
     holders of shares of any class or series of outstanding Voting Stock, other

     (it being intended that the requirements of this paragraph B(ii) shall be
     required to be met with respect to every class of outstanding Voting Stock,
     whether or not the Interested Stockholder has previously acquired any
     shares of a particular class of Voting Stock):

                  (a) (if applicable) the highest per share price (including any
     brokerage commissions, transfer taxes and soliciting dealers' fees) paid by
     the Interested Shareholder for any shares of such class or series of Voting
     Stock acquired by it: (1) within two-year period immediately prior to the

                  (c) the Market Value per share of such class or series of
     Voting Stock on the Announcement Date or on the Determination Date,
     whichever is higher; or

                  (d) the price per share equal to the Market Value per share of
     such class or series of stock determined pursuant to subdivision (ii)(c)
     hereof multiplied by the ratio of (1) the highest per share price
     (including any brokerage commissions, transfer taxes and soliciting
     dealers' fees) paid by the Interested Shareholder for any shares of any
     class or series of Voting Stock acquired by it within the two-year period
     immediately prior to the Announcement Date over (2) the Market Value per
     share of the same class or series of Voting Stock on the first day in such
     two-year period on which the Interested Shareholder acquired any shares of
     the same class or series of Voting Stock.

               (iii) The consideration to be received by holders of a particular
     class or series of outstanding Voting Stock shall be in cash or in the same
     form as the Interested Shareholder has previously paid for shares of such
     class or series of Voting Stock. If the Interested Shareholder has paid for
     shares of any class or series of Voting Stock with varying forms of
     consideration, the form of consideration for such class or series of Voting
     Stock shall be either cash or the form used to acquire the largest number
     of shares of such class or series of Voting Stock previously acquired by
     it.

               (iv) After such Interested Shareholder has become an Interested
     Shareholder and prior to the consummation of such Business Combination: (a)
     there shall have been no failure to declare and pay at the regular date
     therefor any full quarterly dividends (whether or not cumulative) on any
     outstanding preferred stock of the Corporation; (b) there shall have been
     (1) no reduction in the annual rate of dividends paid on any class or
     series of the capital stock of the Corporation (except as necessary to
     reflect any subdivision of the capital stock), and (2) an increase in such
     annual rate of dividends as necessary to reflect any reclassification
     (including any reverse stock split) recapitalization, reorganization or any
     similar transaction which has the effect of reducing the number of
     outstanding shares of common stock; and (c) such Interested Shareholder
     shall have not become the beneficial owner of any additional shares of
     capital stock except as part of the transaction which results in such
     Interested Shareholder becoming an Interested Shareholder or by virtue of
     proportionate stock splits or stock dividends.

         The provisions of subdivisions (iv)(a) and (iv)(b) of this subsection
     do not apply if such actions shall have been approved by the Continuing
     Directors and if no Interested Shareholder or an Affiliate or Associate of
     the Interested Shareholder voted as a director of the Corporation in a
     manner inconsistent with such subdivisions, and the Interested Shareholder,
     within ten days after any act or failure to act inconsistent with such
     subdivisions, notifies the board of directors of the Corporation in writing
     that the Interested Shareholder disapproves thereof and requests in good
     faith that the board of directors rectify such act or failure to act.

<PAGE>

               (v) After such Interested Shareholder has become an Interested
         Shareholder, such Interested Shareholder shall not have received the
         benefit, directly or indirectly (except proportionately as a
         shareholder), of any loans, advances, guarantees, pledges or other
         financial assistance or any tax credits or other tax advantages
         provided by the Corporation or any of its Subsidiaries (whether in
         anticipation of or in connection with such Business Combination or
         otherwise).

               (vi) A proxy or information statement describing the proposed
         Business Combination and complying with the requirements of the
         Securities Exchange Act of 1934 and the rules and regulations
         thereunder (or any subsequent provisions replacing such Act, rules or
         regulations) shall be mailed to public shareholders of the Corporation
         at least 25 days prior to the consummation of such Business Combination
         (whether or not such proxy or information statement is required to be
         mailed pursuant to such Act or subsequent provisions).

     in this Article 10 or as otherwise specifically required by law, no
     amendment of any provision of these Articles of Incorporation shall be made
     unless such amendment has been approved both by the board of directors of
     the Corporation and by the shareholders of the Corporation by the
     affirmative vote of the holders of at least a majority of the shares
     entitled to vote thereon at a duly called annual or special meeting;
     provided, however, that if such amendment is to the provisions set forth in

     approved by the affirmative vote of the holders of at least two-thirds of
     the shares entitled to vote thereon rather than a majority; provided,
     further, that if there are one or more Interested Shareholders (as defined
     in Article 8 hereof), the provisions set forth in this Article 10 or in

     Stock under this clause (b) all the shares of Voting Stock of which the
     beneficial owner is an Interested Shareholder or an Affiliate or Associate
     of such Interested Shareholder (as such terms are defined in Article 8
     hereof).EXHIBIT A TO ENGAGEMENT LETTER

changed by reason of reorganization, merger, consolidation, recapitalization,
reclassification, stock split-up, combination or exchange of Shares and the
like, or dividends payable in Shares, an appropriate adjustment shall be made by
the Board of Directors of the Company in the number of Shares and price per
Share subject to this Warrant. If the Company shall be reorganized,
consolidated, or merged with another corporation, or if all or substantially all
of the assets of the Company shall be sold or exchanged, the Warrant Holder
shall at the time of issuance of the stock under such a corporate event, be
entitled to receive upon the exercise of the Warrants evidenced by this

Warrant and the payment of the exercise price therefor the same number and kind
of shares of stock or the same amount of property, cash or securities as he
would have been entitled to receive upon the occurrence of any such corporate
event as if he had been, immediately prior to such event, the holder of the
number of Shares covered by this Warrant Certificate.

                  2.2 Any adjustment under this Paragraph 2 in the number of
Shares subject to this Warrant Certificate shall apply proportionately to only
the unexercised portion hereunder and shall not have any retroactive effect with
respect to Warrants theretofore exercised. If fractions of a Share would result
from any such adjustment, the adjustment shall be revised to the next lower
whole number of Shares.

                  2.3 No adjustment of the exercise price shall be made if the
amount of such adjustment shall be less than $.10 per Share, but in such case
any adjustment that would otherwise be required then to be made shall be carried
forward and shall be made at the time and together with the next subsequent
adjustment which, together with any adjustment so carried forward, shall amount
to no less than $.10 per Share.

                  2.4 No fractional shares of Common Stock shall be issued upon
the exercise of this Warrant, but in lieu thereof the Company shall pay to the
order of Warrant Holder an amount in cash equal to the same fraction of the
exercise price of one Share on the date of exercise.

                  2.5 When any adjustment is required to be made in the exercise
price or number of Shares subject to this Warrant, the Company shall within
sixty (60) days after the date when the circumstances giving rise to the
adjustment occurred mail to the Warrant Holder a statement describing in
reasonable detail any method used in calculating such adjustment.

         3.       Prior Notice as to Certain Events
                  ---------------------------------

                  The Company shall mail to Warrant Holder not less than ten
(10) days prior to the date on which (a) a record will be taken for the purpose
of determining the holders of the capital stock of the Company entitled to
subscription rights or (b) a record will be taken (or in lieu thereof, the
transfer books will be closed) for the purpose of determining the holders of
such capital stock entitled to notice of and to vote at the meeting of
stockholders at which any consolidation, merger, dissolution, liquidation,
winding up or sale of the Company shall be considered and acted upon.

         4.       Reservation and Issuance of Shares
                  ----------------------------------

                  4.1 The Company covenants and agrees that the Shares issued
upon exercise of this Warrant pursuant to the terms hereof will be duly
authorized, validly issued and, when paid for in accordance with the terms
hereof, fully paid and nonassessable, and free from all liens and charges with
