     A. Number and Par Value of Shares. The Corporation is authorized to issue
one thousand (1,000) shares of capital stock having a par value of $0.003 per
share. All of the shares of stock shall be designated Common Stock, without
preference or distinction.

     B. Assessment of Shares. The capital stock of the Corporation, after the
amount of the par value has been paid, is not subject to assessment to pay the
debts of the Corporation and no stock issued as fully paid up may ever be
assessed, and the Articles of Incorporation cannot be amended in this respect.

     C. Distributions on Partially Paid Shares. Unless otherwise expressly
provided by resolution of the Board of Directors, no distribution shall be made
with respect to any shares of Common Stock which are not fully paid on or before
the date on which such distribution is declared.

     D. Preemptive Rights. No shareholder shall, by reason of holding shares of
any class of stock, have any preemptive or preferential right to purchase or
subscribe for any shares of any class of stock now or hereafter authorized or
any notes, debentures or bonds convertible into or carrying options or warrants
to purchase shares of any class of stock now or hereafter authorized, whether or
not the issuance of any shares, notes, debentures or bonds would adversely
affect the dividend or voting rights of the shareholder.

     E. Cumulative Voting. Cumulative voting for the election of directors is
denied and no shareholder shall have the right to request cumulative voting.




                                   ARTICLE IV
                                 GOVERNING BOARD

     The members of the governing board of the Corporation are designated as
Directors. The initial Board of Directors shall consist of one (1) member. The
name and post office box or street address, either residence or business, of the
sole member of the initial Board of Directors is as follows:

        NAME                              ADDRESS
        Christopher C. Cambria            c/o L-3 Communications Corporation
                                          600 Third Avenue
                                          New York, NY 10016

     The sole member of the initial Board of Directors will serve as the sole
director until the first meeting of the shareholders, or until his successor or
successors are elected and qualified. Thereafter, the number of directors,
whether a fixed number of directors or a variable number of directors with a
fixed minimum and maximum, and the manner in which the number of directors may
increased or decreased, shall be as provided in the bylaws of the Corporation.
Elections of Directors need not be by written ballot except and to the extent
required by the bylaws of the Corporation. The Board of Directors is expressly
authorized to adopt, amend or repeal the bylaws of the Corporation.

                                   ARTICLE V
                       DIRECTORS' AND OFFICERS' LIABILITY

     A. Elimination of Liability. No director or officer of the Corporation will
be liable for damages to the Corporation or its stockholders, unless such
damages are proven to result from acts or omissions which involve (a) breach of
fiduciary duty as a director or officer and (b) such breach of fiduciary duty
involves intentional misconduct, fraud or a knowing violation of law. In the
event that Nevada law is amended to authorize the further elimination or
limitation of liability of directors or officers, then this Article V shall also
be deemed amended to provide for the elimination or limitation of liability to
the fullest extent permitted by Nevada law, as so amended.

     B. Indemnification of Directors and Officers. The Corporation shall
indemnify any and all persons who may serve or who have served at any time as
directors or officers or who at the request of the Board of Directors of the
Corporation, may serve or any time have served as directors or officers of
another corporation in which the Corporation at such time owned or may own
shares of stock or of which it was or may be a creditor, and their respective
heirs, administrators, successors and assigns, against any and all expenses,
including amounts paid upon judgments, counsel fees and amounts paid in
settlement (before or after such suit is commenced), actually and necessarily
incurred by such persons in connection with the defense or settlement of any
claim, action, suit or proceeding in which they, or any of them, are made
parties, or a party, or which may be asserted against them or any of them, by
reason of being or having been directors or officers of the Corporation, or of
such other corporation, to the extent and in the manner permitted by the
Corporate laws of the State of Nevada. Such indemnification



shall be in addition to any other rights to which those indemnified may be
entitled under any law, bylaw, agreement, vote of shareholders or otherwise.

     C. Mandatory Payment of Expenses. The Corporation shall pay the expenses
incurred by a director or officer in defending any civil, criminal,
administrative, or investigative action, suit or proceeding in advance of the
final disposition of such action, suit or proceeding upon receipt of an
undertaking by or on behalf of such director or officer to repay such amount if
it should be ultimately determined that the director or officer is not entitled
to be indemnified by the Corporation as authorized by Nevada law.

     D. Effect of Amendment or Repeal. Any amendment to or repeal of any of the
provisions in this Article V shall not adversely affect any right or protection
of a director or officer of the Corporation for or with respect to any act or
omission of such director or officer occurring prior to such amendment or
repeal.

                                   ARTICLE VI
                          SALE OF CORPORATION'S ASSETS

     The Corporation may sell, lease or exchange all of the Corporation's
property and assets, including the Corporation's good will and corporate
franchises, upon the affirmative vote of a majority of the Board of Directors
and no vote of the shareholders shall be required.

                                    EXHIBIT A

                                   RESOLUTION

     Article VII, "Indemnification of Directors and Officers," of the Articles
of Incorporation of Westwood Corporation, as filed with the Office of the
Secretary of State of the State of Nevada on February 11, 1986, is amended by
the Certificate of Restated and Amended Articles of Incorporation of Westwood
Corporation, dated November 30, 1995, by deleting the following language
contained at the end of the first sentence:

     "except in relation to matters as to which any such director or officer of
     the Corporation, or of such other corporation or former director or officer
     or person shall be adjudged in any action, suit or proceeding to be liable
     for his own negligence or misconduct in the performance of his duty."

and by inserting in lieu thereof the following language:

     "to the extent and in the manner permitted by the Corporate laws of the
     State of Nevada."

so that Article VII now reads as follows:

     "The Corporate shall indemnify any and all persons who may serve or who
     have served at any time as directors or officers or who at the request of
     the Board of Directors of the Corporation, may serve or any time have
     served as directors or officers of another corporation in which the
     Corporation at such time owned or may own shares of stock or of which it
     was or may be a creditor, and their respective heirs, administrators,
     successors and assigns, against any and all expenses, including amounts
     paid upon judgments, counsel fees and amounts paid in settlement (before or
     after such suit is commenced), actually and necessarily incurred by such
     persons in connection with the defense or settlement of any claim, action,
     suit or proceeding in which they, or any of them, are made parties, or a
     party, or which may be asserted against them or any of them, by reason of
     being or having been directors or officers of the Corporation, or of such
     other corporation, to the extent and in the manner permitted by the
     Corporate laws of the State of Nevada. Such indemnification shall be in
     addition to any other rights to which those indemnified may be entitled
     under any law, bylaw, agreement, vote of shareholders or otherwise."
