for cash or other consideration.

   2
ARTICLE IV

        The current resident agent is G. Paul Horst, 5840 Interface Drive, Ann
Arbor, Michigan 48103.

ARTICLE V

        No director of the corporation shall be personally liable to the
corporation or its shareholders for monetary damages for breach of fiduciary
duty as a director, provided that the foregoing shall not eliminate or limit
the liability of a director for any of the following: (i) breach of the
director's duty of loyalty to the corporation or its shareholders; (ii) acts or
omissions not in good faith or that involve intentional  misconduct or knowing
violation of law; (iii) a violation of Section 551(1) of the Michigan Business
Corporation Act; (iv) a transaction from which the director derived an improper
personal benefit or (v) an act or omission occurring prior to the date this
article becomes effective. If the Michigan Business Corporation Act hereafter
is amended to authorize the further elimination or limitation of the liability
of directors, then the liability of a director of the corporation, in addition
to the limitation on personal liability contained herein, shall be limited to
the fullest extent permitted by the amended Michigan Business Corporation Act.
No amendment or repeal of this Article V shall apply to or have any effect on
the liability or alleged liability of any director of the corporation for or
with respect to any acts or omissions of such director occurring prior to such
amendment or repeal.

ARTICLE VI

        A.  Directors and officers of the corporation shall be indemnified in
connection with any actual or threatened action or proceeding (including civil,
criminal, administrative or investigative proceedings) arising out of their
service to the corporation or to another organization at the corporation's
request, and shall be paid expenses incurred in defending any such proceeding
in advance of its final disposition, to the fullest extent permitted by law.
Persons who are not directors or officers of the Company may be similarly
indemnified in respect of such service to the extent authorized at any time by
the Board of Directors or the Bylaws of the corporation. The provisions of this
Article shall be applicable to actions or proceedings commenced after the
adoption hereof, whether arising from acts or omissions occurring before or
after the adoption hereof, and to persons who have ceased to be directors,
officers or employees, and shall inure to the benefit of their heirs, executors
and administrators. The right to indemnification and advancement of expenses
conferred hereunder shall be a contract right which may not be modified
retroactively without the written consent of the director or officer and shall
not be deemed exclusive of any other rights to indemnification or advancement
of expenses such person may have or to which such person may be entitled.

        B.  If a claim under this Article VI is not paid in full by the
corporation within thirty days after a written claim has been received by the
corporation, the indemnitee may at any time thereafter bring suit against the
corporation to recover the unpaid amount of the claim. If successful in whole 

                                       2

   3
or in part in any such suit or in a suit brought by the corporation to recover
advances, the indemnitee shall be entitled to be paid also the expense of
prosecuting or defending such claim. In any action brought by the indemnitee to
enforce a right hereunder (other than an action brought to enforce a claim for
expenses incurred in defending any proceeding in advance of its final
disposition where the required undertaking has been tendered to the
corporation) it shall be a defense that, and in any action brought by the
corporation to recover advances the corporation shall be entitled to recover
such advances if, the indemnitee has not met the applicable standard of conduct
set forth in the Michigan Business Corporation Act. Neither the failure of the
corporation (including its Board of Directors, a committee of its Board of
Directors, independent legal counsel, or its shareholders) to have made a
determination prior to the commencement of such action that indemnification of
the indemnitee is proper in the circumstances because the indemnitee has met
the applicable standard of conduct set forth in the Michigan Business
Corporation Act, nor an actual determination by the corporation (including its
Board of Directors, a committee of its Board of Directors, independent legal
counsel, or its shareholders) that the indemnitee has not met such applicable
standard of conduct, shall be a defense to an action brought by the indemnitee
or create a presumption that the indemnitee has not met the applicable standard
of conduct. In any action brought by the indemnitee to enforce a right
hereunder or by the corporation to recover payments by the corporation of
advances, the burden of proof shall be on the corporation.

ARTICLE VII

        A.  The number of directors constituting the entire Board of Directors
shall not be less than three nor more than twelve, the exact number of
directors to be fixed from time to time only by vote of a majority of the Board
of Directors. The Board of Directors shall be divided into three classes as
nearly equal in number as possible, with the term of office of one class
expiring each year. The first class of the Board of Directors shall be elected
to hold office for a term expiring at the annual meeting of shareholders in
1994; directors of the second class shall be elected to hold office for a term
expiring at the next succeeding annual meeting of shareholders; and directors
of the third class shall be elected to hold office for a term expiring at the
third succeeding annual meeting of shareholders, and in each case, until their
respective successors are elected and have qualified, or until their earlier
death, resignation or removal. At each annual election held after the initial
classification and election in the manner provided above, a number of directors
equal to the number of the class whose term expires at the time of the meeting
shall be elected to hold office until the end of the third succeeding annual
meeting of shareholders after their election and until their respective
successors are elected and have qualified, or until their earlier death,
resignation or removal. When the number of directors is changed, any newly
created directorships or any decrease in directorships shall be so apportioned
among the classes so as to make all classes as nearly equal in number as
possible. No decrease in the number of directors constituting the Board of
Directors shall shorten the term of any incumbent director.


                                       3
   4
        B.  During the intervals between annual meetings of shareholders, any
vacancy occurring in the Board of Directors caused by resignation, removal,
death or other incapacity, and any newly created directorships resulting from
an increase in the number of directorships shall be filled by a majority vote
of the directors then in office, whether or not a quorum, or, if there are no
directors in office, by the shareholders. If the Board of Directors accepts the
resignation of any director or officer to take effect at a future time, it
shall have the power to elect a successor who shall take office when the
resignation becomes effective. Each director chosen to fill a vacancy or chosen
to fill a newly created directorship shall hold office until the next election
for the class for which such director shall have been chosen and until the
election and qualification of his successor, or until his earlier death,
resignation or removal. A director or directors or the entire Board of
Directors may be removed from office only for cause.

        C.  The affirmative vote of the holders of at least 80% of the
outstanding shares of the capital stock of the corporation entitled to vote
generally in the elections of directors shall be required to amend, repeal or
adopt any provision inconsistent with this Article VII.

        These Restated Articles of Incorporation were duly adopted on the 25th
day of January, 1993 in accordance with the provisions of Section 642 of the
Michigan Business Corporation Act, and were duly adopted by the sole
shareholder at a meeting of its board of directors held January 25, 1993.

                Signed this 12th day of February, 1993

                  Incorporation of Nematron in effect on the effective date of
                  the merger will remain the Amended and Restated Articles of
                  Incorporation of the Surviving Corporation without any
                  modification or amendment in the merger. The Amended and
                  Restated Bylaws of Nematron will remain the Amended and
                  Restated Bylaws of the Surviving Corporation, except that they
                  will be amended as provided in the Agreement and Plan of
                  Merger between the constituent corporations dated February 2,
                  1995 (the "Merger Agreement").

           (iii)  Directors and Officers.  The directors and officers of
                  Nematron in office at and as of the effective date of the
                  merger will remain the directors and officers of the Surviving
                  Corporation. In addition, the number of seats on the Surviving
                  Corporation's Board of Directors will be increased by three
                  seats, and three directors designated by ISI, who have
                  satisfied the selection criteria in Nematron's Amended and
                  Restated Bylaws, will be appointed to the Surviving
                  Corporation's Board of Directors.

            (iv)  Common Stock of ISI.  On the effective date of the merger: (i)
                  each share of ISI common stock issued and outstanding
                  immediately prior to the effective date of the merger (other
                  than a share of ISI common stock with respect to which
                  Nematron has received notice of the exercise of dissenters'
                  rights under the Virginia Stock Corporation Act (a "Dissenting
                  Share")) shall, ipso facto and without any action on the part
                  of the holder thereof, be converted into and represent the
                  right (A) to receive 0.56798 shares of Nematron common stock,
                  and (B) to receive cash in lieu of any fractional share of
                  Nematron common stock that would otherwise be issuable, and
                  (ii) each Dissenting Share will have the rights set forth in
                  the Virginia Stock Corporation Act. In addition, the Merger
                  Agreement provides that, after the effective date of the
                  merger, the Surviving Corporation will issue a warrant to
                  purchase one share of Nematron common stock for every two
                  shares of Nematron common stock issued in the merger only if
                  certain conditions precedent set forth in the Merger Agreement
                  are satisfied. Regardless of whether a holder of ISI common
                  stock shall have received a certificate for Nematron common
                  stock issued in the merger, no certificate representing ISI
                  common stock shall be deemed to be outstanding or to have
                  rights other than the right to receive the merger
                  consideration described above, or to dissent from the merger
                  and have the rights specified by the Virginia Stock
                  Corporation Act. Each holder of a certificate representing ISI
                  common stock (other than Dissenting Shares), upon surrender to
                  Nematron of the stock certificate or certificates representing
                  ISI common stock and the investment representation letter
                  described in the Merger Agreement, shall be entitled to
                  receive the merger consideration. After the effective date of
                  the merger, there shall be no transfer of ISI common stock on
                  the stock transfer books of ISI. The procedures for payment of
                  the merger consideration are further described in the Merger
                  Agreement.

   12
                (v)  Common Stock of Nematron.  Each share of common stock of
                     Nematron issued and outstanding on the effective date of
                     the merger, shall, ipso facto and without any action on the
                     part of the holder thereof, be converted into one share of
                     the common stock of the Surviving Corporation. Outstanding
                     certificates of Nematron shall be deemed to represent the
                     number of outstanding shares of common stock of the
                     Surviving Corporation into which they have been converted,
                     and need not be exchanged for new certificates of the
                     Surviving Corporation by any holder thereof.

        f.  Not applicable, as the Amended and Restated Articles of
Incorporation of Nematron will not be amended as a result of the merger.

        g.  Not applicable, as the terms and conditions of the merger are
described in 1(e) above.

2.  The merger is permitted under the laws of the Commonwealth of Virginia, the
jurisdiction under which ISI is organized, and the Plan of Merger was adopted
and approved by such corporation pursuant to and in accordance with the laws of
that jurisdiction.

3.  Not applicable, as the constituent corporations desire that the merger be
effective upon the date of the filing of this Certificate of Merger with the
Michigan Department of Commerce.

4.  The Plan of Merger was approved by the Board of Directors of Nematron and
ISI. In addition, the Plan of Merger was approved by the shareholders of ISI.
Neither Section 703a nor Section 754 of the Michigan Business Corporation Act
requires the shareholders of Nematron to approve the Plan of Merger. The Plan
of Merger, and the related Merger Agreement referred to herein, will be
furnished by the Surviving Corporation, on request and without cost, to any
shareholder of any constituent corporation.
