                                   Annex A

                            SERIES B PREFERRED STOCK


         The powers, designations, preferences and relative, participating,
optional or other rights of the Series B Preferred Stock of Code-Alarm Inc.
(the "Corporation") are as follows:

     1.  DESIGNATION AND AMOUNT.

         This series of preferred stock shall be designated as "Series B 
Preferred Stock" and shall have no par value per share.  The number of
authorized shares constituting this series shall be one share.

     2.  DIVIDENDS.

         (1)  Right to Receive Dividends.  The holders of Series B Preferred 
Stock shall be entitled to receive, when and as declared by the Board of
Directors, to the extent permitted by the Michigan Business Corporation Act,
cumulative dividends in preference to any dividend on the Common Stock but not
in preference to any dividend on any other class or series of stock of the
Corporation at the rate of $1.00 per share per annum, payable in arrears, on
December 31 of each year, commencing with December 31, 1998.  The dividend for
a period which is less than or more than a year shall be pro rated based upon
the number of days.  Any dividend not paid shall accrue and be payable when and
if declared by the Board of directors or upon redemption or repurchase of the
Series B Preferred Stock or the liquidation of the Corporation.

     3.  LIQUIDATION.

         In the event of any bankruptcy, liquidation, dissolution or winding up
of the Corporation, either voluntary or involuntary, the holders of Series B
Preferred Stock shall be entitled to receive, prior and in preference to any
distribution of any surplus funds of the Corporation to the holders of the
Common Stock by reason of their ownership thereof, but not in preference to any
distribution of any surplus funds of the Corporation to the holders of any
other class or series of stock of the Corporation, an amount equal to (i) Ten
Dollars ($10.00) per share plus (ii) all accrued but unpaid dividends on such
share (the "Liquidation Preference").

     4.  VOTING RIGHTS.

         The holder of the Series B Preferred Stock shall have the following 
voting rights:

         (1)  Election of Directors.

              If (i) there is an Event of Default under the Credit Agreement
dated as of October 24, 1997, among the Corporation, as Borrower, and the other
Credit Parties identified




   3

therein, General Electric Capital Corporation, as Agent and Lender (as it may
be amended, supplemented or modified, the "Credit Agreement"), and  (ii) Agent
accelerates payment of the Obligations (as defined in the Credit Agreement),
then the number of authorized directors shall be increased by an amount equal
to one plus the then number of directors (e.g., if before the Event of Default,
the Bylaws authorize 9 directors, the number shall be increased to 19), and the
holder of the Series B Preferred Stock shall be entitled to designate from time
to time (without the necessity of a meeting of shareholders) the persons to
fill the directorships thus created.  If the Event of Default is cured or
waived and if acceleration is thereafter rescinded, the number of authorized
directors shall be decreased by the amount previously increased as provided in
this section and the term of any director so elected shall immediately
terminate.  If the Board of Directors of the Corporation has been divided into
two or three classes with terms of each class expiring at a different annual
meeting, then the terms of the directors which the Series B Preferred Stock can
elect pursuant to this Section 4(a) shall likewise be divided into classes,
with the number of directors in each class being as nearly equal as possible
and with the terms of the first class expiring at the first annual meeting
following their election, the terms of the second class expiring at the second
annual meeting following their election and, if applicable, the terms of the
third class expiring at the third annual meeting following their election.  At
each annual meeting after such classification, 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 second succeeding annual meeting if there are
two classes or until the third succeeding annual meeting if there are three
classes; however, the terms of each director elected by the Series B Preferred
Stock shall terminate as provided in this Section 4(a).

         (2)  Certain Corporate Actions.

              So long as the Series B Preferred Stock is outstanding, the 
Corporation shall not, without the affirmative vote or written consent of
the holder of the Series B Preferred Stock amend, repeal, modify or supplement
any provision of the Restated Articles of Incorporation, any certificate
setting forth the rights, preferences and privileges of any series of capital
stock pursuant to the authority of the Board of Directors to authorize such
series, the By-laws of the Corporation, as in effect on October 15, 1997, or
any successor bylaws or this Certificate of Designation, Number, Powers,
Preferences and Relative, Participating, Optional and Other Rights of Series B
Preferred Stock (the "Certificate of Designation"), if such amendment, repeal,
modification or supplement in any way adversely affects the powers,
designations, preferences, or other rights of the Series B Preferred Stock.

         (3)  Other Matters.

              Except as provided in subsections (a) and (b) of this Section 4 
or as required by law, the holder of Series B Preferred Stock shall have no
right to vote on any matter presented to the stockholders of the Corporation.
  
     5.  REPURCHASE.

         Upon payment in full of the Obligations and termination of the 
Commitments (as such terms are defined in the Credit Agreement referred to
in Section 4), the Corporation shall be entitled to repurchase each share of
Series B Preferred Stock then outstanding for an amount equal to its
Liquidation Preference, upon giving written notice of not less than five days
to the holder thereof.
