                           RESOLVED: That Article IV of the Articles of
                  Incorporation be amended to read in full as follows:

                           This corporation is authorized to issue two classes
                  of shares of stock to be designated, respectively, Preferred

                  classes of stock which this corporation shall have authority
                  to issue is Five Million Five Hundred Thousand (5,500,000).
                  The aggregate par value of all shares having par value shall
                  be Six Million Two Hundred Fifty Thousand Dollars
                  ($6,250,000). The number of shares of Preferred Stock shall be
                  Five Hundred Thousand (500,000), with each share having a par
                  value of Ten Dollars ($10.00), with the aggregate par value of
                  all such shares being Five Million Dollars ($5,000,000). The

                  (5,000,000), with each share having a par value of Twenty-five

                  being One Million Two Hundred Fifty Thousand Dollars
                  ($1,250,000). Upon

                  each outstanding share of Common Stock, par value One Dollar
                  ($1.00) per share, is automatically converted into or
                  reconstituted as one share of Common Stock, par value

                                    Preferred Stock may be issued from time to
                  time, in one or more series, each such series to have such a
                  distinctive designation or title as may be fixed by the Board
                  of Directors prior to issuance of shares thereof. The number
                  of shares of Preferred Stock constituting each such series
                  shall be fixed by the Board of Directors prior to issuance of
                  any shares in such series. The Board of Directors is hereby

                  number of shares constituting any outstanding series, the
                  number of shares of which is theretofore fixed by the
                  directors. The

                  Directors by appropriate resolution or resolutions, and upon
                  each such determination of the Board of Directors shall
                  require the officers of this corporation to file a Certificate
                  of Determination of Preferences with the Secretary of State of
                  the State of California in the form and manner then required
                  by the California Corporations Code. All shares of Preferred
                  Stock shall be of equal rank and shall be identical in all
                  respects except in respect of the particulars that may be
                  fixed by the Board of Directors as in Article Four provided;
                  and all shares within each series shall be identical in all

                           "That at a meeting of the board of directors of said
                  corporation, duly held at Torrance, California, on January 2,
                  1970, the following resolution was adopted:

                           RESOLVED:  That Article IV of the Articles of
                  Incorporation be amended to read in full as follows:

                           This corporation is authorized to issue two classes
                  of shares of stock to be designated, respectively, Preferred
                  Stock and Common Stock. The total number of shares of all
                  classes of stock which this corporation shall have authority
                  to issue is Five Million Five Hundred Thousand (5,500,000).
                  The aggregate par value of all shares having par value shall
                  be Six Million Two Hundred Fifty Thousand Dollars
                  ($6,250,000). The number of shares of Preferred Stock shall be
                  Five Hundred Thousand (500,000), with each share having a par
                  value of Ten Dollars ($10.00), with the aggregate par value of
                  all such shares being Five Million Dollars ($5,000,000).



                  The number of shares of Common Stock shall be Five Million
                  (5,000,000), with each share having a par value of Twenty-five
                  Cents ($.25), with the aggregate par value of all such shares
                  being One Million Two Hundred Fifty Thousand Dollars
                  ($1,250,000). Upon the amendment of this Article IV as
                  hereinabove set forth, each outstanding share of Common Stock,
                  par value One Dollar ($1.00) per share, is automatically
                  converted into or reconstituted as four shares of Common
                  Stock, par value Twenty-five Cents ($.25) per share.

                           Set forth below is the manner in which Preferred
                  Stock may be issued in series, the manner in which the rights
                  and preferences of the Preferred Stock are to be determined,
                  and the rights of the Common Stock.

                           (1)      Preferred Stock.

                                    Preferred Stock may be issued from time to
                  time, in one or more series, each such series to have such a
                  distinctive designation or title as may be fixed by the Board
                  of Directors prior to issuance of shares thereof. The number
                  of shares of Preferred Stock constituting each such series
                  shall be fixed by the Board of Directors prior to issuance of
                  any shares in such series. The Board of Directors is hereby
                  further authorized to fix or alter, from time to time, the
                  dividend rights, dividend rate, conversion rights, voting
                  rights, the rights and terms of redemption (including sinking
                  fund provisions), the redemption price or prices and the
                  liquidation preferences of any wholly unissued series of
                  shares of Preferred Stock, and to increase or decrease (but
                  not below the number of such series then outstanding), the
                  number of shares constituting any outstanding series, the
                  number

                                      -2-


                  of shares of which is theretofore fixed by the directors. The
                  description and terms of the Preferred Stock of each wholly
                  unissued series in respect of the foregoing particulars are
                  hereby authorized to be fixed and determined by the Board of
                  Directors by appropriate resolution or resolutions, and upon
                  each such determination of the Board of Directors shall
                  require the officers of this corporation to file a Certificate
                  of Determination of Preferences with the Secretary of State of
                  the State of California in the form and manner then required
                  by the California Corporations Code. All shares of Preferred
                  Stock shall be of equal rank and shall be identical in all
                  respects except in respect of the particulars that may be
                  fixed by the Board of Directors as in Article IV provided; and
                  all shares within each series shall be identical in all
                  respects. Each series of Preferred Stock may differ from any
                  or every other series of Preferred Stock as may be determined
                  from time to time by the Board of Directors prior to the
                  issuance of any shares of such series.

                           (2)      Common Stock.

                           Subject to the prior rights of the holders of
                  Preferred Stock as provided by law or in the Articles of
                  Incorporation of this corporation or by the Board of Directors
                  pursuant to the authority granted in this Article IV, the
                  holders of Common Stock shall have and possess all (i) rights
                  to dividends as may be declared and paid out of funds of this
                  corporation legally available for such payment in such amounts
                  and at such times as the Board of Directors may determine;
                  (ii) voting rights and powers; and (iii) rights to receive the
                  assets of the corporation upon liquidation

                  dissolution or winding up of the corporation, whether by
                  voluntary or involuntary action.

         5.       That said paragraph "2", as corrected, conforms the wording of
the resolution set forth therein to the wording of the resolution as adopted by
the board of directors at a meeting held in Torrance, California on January 2,
1970, and to the wording of the amended article as set forth in the
shareholders' written consent.
