                                      -4-



   5


Delaware Code or on the application of trustees in dissolution or of any
receiver or receivers appointed for this corporation under the provisions of
section 279 of Title 8 of the Delaware Code order a meeting of the creditors or
class of creditors, and/or of the stockholders or class of stockholders, of this
corporation, as the case may be, to be summoned in such manner as the said court
directs. If a majority in number representing three-fourths in value of the
creditors or class of creditors, and/or of the stockholders or class of
stockholders of this corporation, as the case may be, agree to any compromise or
arrangement and to any reorganization of this corporation as consequence of such
compromise or arrangement, the said compromise or arrangement and the said
reorganization shall, if sanctioned by the court to which the said application

all the stockholders or class of stockholders, of this corporation, as the case
may be, and also on this corporation.

        EIGHTH. Meetings of stockholders may be held within or without the State

provide.

        NINTH. (a) The corporation shall indemnify any person who was or is a
party or is threatened to be made a party to any threatened, pending or
completed action, suit or proceeding, whether civil, criminal, administrative or
investigative (other than an action by or in the right of the corporation) by
reason of the fact that he is or was a director, officer, employee or agent of
the corporation, or is or was serving at the request of the corporation as a
director, officer, employee or agent of another corporation, partnership, joint
venture, trust or other enterprise, including service with respect to employee
benefit plans, against expenses (including attorneys' fees and ERISA excise
taxes or penalties), judgments, fines and amounts paid in settlement actually
and reasonably incurred by him in connection with such action, suit or
proceeding if he acted in good faith and in a manner he reasonably believed to
be in or not opposed to the best interests of the corporation, and, with respect
to any criminal action or proceeding, had no reasonable cause to believe his
conduct was unlawful. The termination of any action, suit or proceeding by
judgment, order, settlement, conviction, or upon a plea of nolo contendere or
its equivalent, shall not, of itself, create a presumption that the person did
not act in good faith and in a manner which he reasonably believed to be in or
not opposed to the best interests of the corporation, and, with respect to any
criminal action or proceeding, had reasonable cause to believe that his conduct
was unlawful.

        (b) The corporation shall indemnify any person who was or is a party or
is threatened to be made a party to any threatened, pending or completed action
or suit by or in the right of the corporation to procure a judgment in its favor
by reason of the fact that he is or was a director, officer, employee or agent
of the corporation, or is or was serving at the request of the corporation as a
director, officer, employee or agent of another corporation, partnership, joint
venture, trust or other enterprise, including service with respect to employee
benefit plans, against expenses (including attorneys' fees and ERISA excise
taxes or penalties), actually and reasonably incurred by him in connection with
the defense or settlement of such action or suit if he acted in good faith and
in a manner he reasonably believed to be in or not opposed to the best interests
of the corporation and except that no indemnification shall be made in respect
of any claim, issue or matter as to which such person shall have been adjudged
to be liable to the corporation unless and only to the extent that the court in
which such action or suit was brought shall determine upon application that,
despite the adjudication of liability but in view of all the circumstances of
the case, such person is fairly and reasonably entitled to indemnity for such
expenses which such court shall deem proper.

        (c) To the extent that a director, officer, employee or agent of the
corporation has been successful on the merits or otherwise in defense of any
action, suit or proceeding referred to in paragraphs (a) and (b) of this Article
Ninth or in defense of any claim, issue or matter therein, he shall be
indemnified by the corporation against expenses (including attorneys' fees)
actually and reasonably incurred by him in connection therewith.

        (d) Any indemnification under paragraphs (a) and (b) of this Article
Ninth, unless ordered by a court, shall be made by the corporation only as
authorized in the specific case upon a determination that indemnification of the
director, officer, employee or agent is proper in the circumstances because he
has met the applicable standard of conduct set forth in said paragraphs (a) and
(b). Such determination shall be made (i) by the Board of Directors by a
majority vote of a quorum consisting of directors who were not parties to such
action, suit, or proceeding, or (ii) if such a quorum is not obtainable, or even
if obtainable and a quorum of disinterested directors so directs, by independent
legal counsel (compensated by the corporation) in a written opinion, or (iii) by
the stockholders.

        (e) Expenses incurred in defending a civil or criminal action, suit or
proceeding may be paid by the corporation in advance of the final disposition of
such action, suit or proceeding upon receipt of an undertaking by or on behalf
of the director, officer, employee or agent to repay such amount if it shall
ultimately be determined that he is not entitled to be indemnified by the
corporation as authorized in this Article. 

                                       -6-



   7


        (f) The indemnification and advancement of expenses provided by or
granted pursuant to this Article shall not be deemed exclusive of any other
rights to which those seeking indemnification or advancement of expenses may be
entitled under any by-law, agreement, vote of stockholders or disinterested
directors or otherwise, both as to action in his official capacity and as to
action in another capacity while holding such office, and shall continue as to a
person who has ceased to be a director, officer, employee or agent and shall
inure to the benefit of the heirs, executors and administrators of such a
person.

        (g) The corporation may purchase and maintain insurance on behalf of any
person who is or was a director, officer, employee or agent of the corporation,
or is or was serving at the request of the corporation as a director, officer,
employee or agent of another corporation, partnership, joint venture, trust or
other enterprise against any liability asserted against him and incurred by him
in any such capacity, or arising out of his status as such, whether or not the
corporation would have the power to indemnify him against such liability under
the provisions of this Article or of applicable law. The indemnification rights
conferred in this Article Ninth shall be contract rights between the corporation
and the officer or director or other individual entitled to indemnification.

        (h) A director of the corporation shall not be personally liable to the
corporation or its stockholders for monetary damages for breach of fiduciary
duty as a director, except for liability (i) for any breach of the director's
duty of loyalty to the corporation or its stockholders, (ii) for acts or
omissions not in good faith or which involve intentional misconduct or a knowing
violation of law, (iii) under section 174 of the Delaware General Corporation
Law, or (iv) for any transaction from which the director derived an improper
personal benefit.

        TENTH. The corporation reserves the right to amend, alter, change or
repeal any provision contained in this Certificate of Incorporation, in the
manner now or hereafter prescribed by statute, and all rights conferred upon
stockholders herein are granted subject to this reservation.

beneficial owner, the provisions of this paragraph 1 shall not apply, and the
provisions of Delaware law shall apply.

        2. The provisions of paragraph (1) of this Article shall not apply, and
the provisions of Delaware law shall apply to (a) any transaction described
therein if the Board of Directors by resolutions shall have approved a
memorandum of understanding with such other person setting forth the principal

     Newcor, Inc., a corporation organized and existing under and by virtue of
the General Corporation Law of the state of Delaware, DOES HEREBY CERTIFY:

     FIRST: that at a meeting of the Board of Directors of said corporation,
resolutions were duly adopted setting forth proposed amendments to the Restated
Certificate of Incorporation of said corporation, declaring said amendments
to be advisable and calling a meeting of the Stockholders of said corporation
for consideration thereof. The resolutions setting forth the proposed amendments
are as follows:

     1. RESOLVED, that the Restated Certificate of Incorporation of Newcor, Inc.
     be amended by changing Article Fourth thereof so that, as amended, said
     Article shall be and read in its entirety as follows:

               "FOURTH. The total number of shares of stock of all classes which
          the corporation shall have authority to issue is 11 million 
          (11,000,000) of which 10 million (10,000,000) shall be shares of
          Common Stock with a par value of one dollar ($1.00) per share, and one
          million (1,000,000) shall be shares of Preferred Stock without par
          value.

               Each share of Common Stock shall entitle the holder thereof to 
          one vote, in person or by proxy, at any and all meetings of the
          stockholders of the corporation.
        
               The Preferred Stock shall be issuable in series, and in
          connection with the issuance of any series of Preferred Stock and to
          the extent now or hereafter permitted by the laws of the State of
          Delaware, the Board of Directors is authorized to fix by resolution
          the designation of each series, the stated value of the shares of each
          series, the dividend rate of each series and the date or dates or
          other provisions respecting the payment of dividends, the provisions,
          if any, for a sinking fund for the shares of each series, the
          preferences, of the shares of each series in the event of


   14


          liquidation or dissolution of the corporation, the provisions, if any,
          respecting the redemption of the shares of each series and subject to
          requirements of the laws of the State of Delaware, the voting rights
          (except that such shares shall not have more than one vote per share),
          the terms, if any, upon which the shares of each series shall be
          convertible into or exchangeable for any other shares of stock of the
          corporation and any other relative, participating, optional or other
          special rights, and qualifications, limitations or restrictions
          thereof, of the shares of each series."

     2.   RESOLVED, that the Restated Certificate of Incorporation of Newcor, 
     Inc. be amended by adding thereto a new Article Thirteenth to read in its
     entirety as follows:
        
               "THIRTEENTH. At the 1992 annual meeting of the shareholders
          of the corporation, the directors of the corporation shall be divided
          into three classes with respect to the time that they severally hold
          office, as nearly equal in number as possible, with the initial term 
          of office of the first class of directors to expire at the 1993 annual
          meeting of shareholders, the initial term of office of the second
          class of directors to expire at the 1994 annual meeting of
          shareholders, and the initial term of the third class of directors to
          expire at the 1995 annual meeting of shareholders. Commencing with the
          1993 annual meeting of shareholders, directors elected to succeed
          those directors whose terms have expired at such meeting shall be
          elected for a term of office to expire at the third succeeding annual
          meeting of shareholders after their election. If the number of
          directors constituting the entire Board of Directors is changed, any
          increase or decrease shall be apportioned among the classes so as to
          maintain or attain, if possible, the equality of the number of
          directors in each class. If such equality is not possible, the
          increase or decrease shall be apportioned among the classes in such a
          way that the difference between the number of directors in any two
          classes shall not exceed one. In no case, however, shall a decrease
          in the number of directors shorten the term of any incumbent
          director."

     SECOND: That thereafter, pursuant to resolution of its board of directors,
an annual meeting of the stockholders of said corporation was duly called and
held, upon notice and in accordance with Section 222 of the General Corporation
Law of the State of Delaware at which meeting the necessary number of votes of
shares as required by statute were voted in favor of the amendment.

                                       -2-

     THIRD: That the aforesaid amendments were duly adopted in accordance with
the applicable provisions of Section 242 of the General Corporation Law of the
State of Delaware.
