ARTICLE III

The total authorized shares:

1.      Common Shares           6,000,000, par value $0.01 per share

        Preferred Shares        1,000,000, par value $0.01 per share

2.      A statement of all or any of the relative rights, preferences and
        limitations of the shares of each class is as follows:

               a.      Preferred Shares.  The Board of Directors may cause the
        Corporation to issue Preferred Shares in one or more series, each series
        to bear a distinctive designation and to have such relative rights and
        preferences as shall be prescribed by resolution of the Board.  Such
        resolutions, when filed, shall constitute amendments to these Articles
        of Incorporation. 

               b.      Reverse Stock Split.  Effective as of the close of
        business on the date of filing these Restated Articles of
        Incorporation (the "Effective Time"), the filing of these Restated
        Articles of Incorporation shall effect a reverse stock split on the
        basis of one new Common Share for each ten then issued and outstanding
        Common Shares, while maintaining the number of authorized Common Shares
        and Preferred Shares, and their par values, as set forth in this Article
        III (the "Reverse Split").

               Immediately as of the Effective Time, and without any action by
        the holders of outstanding Common Shares, but subject to the redemption
        of fractional shares described below, outstanding certificates
        representing the Corporation's Common Shares shall represent for all
        purposes, and each Common Share issued and outstanding immediately
        before the Effective Time shall automatically be converted into, new
        Common Shares in the ratio of ten old Common Shares for one new Common
        Share, all by virtue of the Reverse Split and without any action on the
        part of the holder of such Common Shares.
 
               Notwithstanding any of the foregoing to the contrary, no scrip 
        or fractional Common Shares shall be issued in connection with the 
        Reverse Split.  In lieu thereof each record holder of Common Shares as
        of the Effective Date who would otherwise have been entitled to 
        receive a fractional new Common Share shall, upon surrender of such 
        shareholder's certificates representing pre-split Common Shares, be 
        entitled to receive a cash payment equal to the closing sale price of
        one Common Share on The Nasdaq SmallCap Market on the Effective
        Date, or, if there are no reported sales on such date, the average of
        the last reported high bid and low asked prices on such day multiplied
        by the fractional share which would otherwise be issuable after
        giving effect to the Reverse Split, and such amount shall in no event
        accrue any interest. As of the Effective Time such fractional shares
        shall no longer  represent equity interests in the Corporation, and
        shall not be  entitled to any voting, dividend or other shareholder
        rights; rather,  they shall represent only the right to receive the
        cash payment described in this paragraph.

is proposed between this corporation and its creditors or any class of them or
between this corporation and its shareholders or any class of them, a court of
equity jurisdiction within the state, on application of this corporation or of a

the corporation, may order a meeting of the creditors or class of creditors or
of the shareholders or class of shareholders to be affected by the
proposed compromise or arrangement or reorganization, to be summoned in such
manner as the court directs.  If a majority in number representing 3/4 in value
of the creditors or class of creditors, or of the shareholders or class of
shareholders to be affected by the proposed compromise or arrangement or a
reorganization, agree to a compromise or arrangement or a reorganization of this
corporation as a consequence of the compromise or arrangement, the compromise or
arrangement and the reorganization, if sanctioned by the court to which the
application has been made, shall be binding on all the creditors or class of
creditors, or on all the shareholders or class of shareholders and also on this
corporation.

ARTICLE VI
--------------------------------------------------------------------------------
     A director of the Corporation shall not be personally liable to the
Corporation or its shareholders for monetary damages for breach of the
director's fiduciary duty.  However, this Article VI shall not eliminate or
limit the liability of a director for any of the following:

          (1)     A breach of the director's duty of loyalty to the Corporation
     or its shareholders.

          (2)     Acts or omissions not in good faith or that involve
     intentional misconduct or knowing violation of law.

          (3)     A violation of Section 551(1) of the Michigan Business
     Corporation Act.

          (4)     A transaction from which the director derived an improper
     personal benefit.

          (5)     An act or omission occurring before the effective date of
     this Article VI.

Any repeal or modification of this Article VI by the shareholders of the
Corporation shall not adversely affect any right or protection of any director
of the Corporation existing at the time of, or for or with respect to, any acts
or omissions occurring before such repeal or modification.

ARTICLE VII
        The business and affairs of the Corporation shall be managed by or
under the direction of a Board of Directors consisting of not less than three or
more than fifteen directors, the exact number of directors to be determined
from time to time solely by a resolution adopted by an affirmative vote of a
majority of the directors then in office.  The directors shall be divided into
three classes, designated Class I, Class II and Class III.  Each class shall
consist, as nearly as may be possible, of one-third of the total number of
directors constituting the entire Board of Directors.  At the 1992 Annual
Meeting of Shareholders, Class I director shall be elected for a one-year term,
Class II directors for a two-year term and Class III directors for a three-year
term.  At each succeeding annual meeting of shareholders, commencing in 1993,
successors to the class of directors whose term expires at that annual meeting
shall be elected for a three-year term.

        If the number of directors is changed, any increase or decrease shall
be apportioned among the classes of directors so as to maintain the number of
directors in each class as nearly equal as possible, but in no case will a
decrease in the number of directors shorten the term of any incumbent
director.  When the number of directors is increased by the Board of Directors
and any newly-created directorships are filled by the Board, the additional
directors shall be classified as provided by the Board.

        A director shall hold office until the meeting for the year in which
his or her term expires and until his or her successor shall be elected and 
shall qualify, subject, however, to prior death, resignation, retirement,
disqualification or removal from office.  Newly created directorships resulting
from an increase in the number of directors and any vacancy on the Board of
Directors may be filled by an affirmative vote of a majority of the directors
then in office.  If the number of directors then in office is less then a
quorum, such newly created directorships and vacancies may be filled by a
majority of the directors then in office, although less than a quorum, or by
the sole remaining director.  A director elected by the Board of Directors to
fill a vacancy shall hold office until the next election successor of the class
for which the director shall have been chosen and until his or her shall be
elected and shall qualify.  A director or the entire Board of Directors may be
removed only for cause.

        Notwithstanding the foregoing, whenever the holders of any one or more
classes of Preferred Shares or series thereof issued by the Corporation shall
have the right, voting separately by class or series, to elect directors at an
annual or special meeting of shareholders, the election, term of office, filling
of vacancies and other features of such directorship shall be governed by the
terms of these Restated Articles of Incorporation applicable thereto, and such
directors so elected shall not be divided into classes pursuant to this Article.

        This Article VII may only be amended by the affirmative vote of holders
of 90% of the outstanding Common Shares of the Corporation, in addition to the
vote otherwise required by the Michigan Business Corporation Act.
