                                       II.

        The purpose of the Corporation is to engage in any lawful act or
activity for which a corporation may be organized under the General Corporation

to or imposed upon any wholly unissued series of Preferred Stock, and to fix the
number of shares of any series of Preferred Stock and the designation of any
such series of Preferred Stock. The board of directors, within the limits and
restrictions stated in any resolution or resolutions of the board of directors
originally fixing the

decrease (but not below the number of shares of such series then outstanding)

series.

subsequently amended) not otherwise applicable to this Corporation under Chapter
23 of said General Corporation Law.

                            CERTIFICATE OF AMENDMENT
                                       OF
                       RESTATED ARTICLES OF INCORPORATION
                                       OF
                                  COMARCO, INC.


                Thomas A. Franza and Evelyn Evans certify that:

1.                        They are the President and Secretary, respectively, of
Comarco, Inc., a California corporation.

2.                        Paragraph 1 of Article III of the Restated Articles of
Incorporation of this Corporation is amended to read in its entirety as follows:

                "The Corporation is authorized to issue two classes of shares
                designated "Preferred Stock" and "Common Stock", respectively.
                The number of shares of Preferred Stock authorized to be issued
                is 10,000,000 and the number of shares of Common Stock
                authorized to be issued is 50,625,000. Effective upon the filing
                of this Certificate of Amendment, every one (1) outstanding
                share of Common Stock is split into one and one-half (1.5)
                shares of Common Stock. In lieu of any fractional share to which
                a holder would otherwise be entitled, the Corporation shall pay
                cash equal to such fraction multiplied by the fair market value
                of one share of Common Stock (post-split) as determined by the
                Board of Directors of the Corporation."

3.                        The foregoing amendment of the Restated Articles of
Incorporation was approved by unanimous vote of the Board of Directors pursuant
to Section 902(c) of the California Corporations Code, and was entitled to be
approved by the Board of Directors alone pursuant to Section 902(c) because the
foregoing amendment effects only a stock split and a proportionate increase in
the number of authorized shares of Common Stock. The Corporation is authorized
to issue two (2) classes of shares, Preferred Stock and Common Stock, and only
one (1) class of shares, Common Stock, is outstanding.

4.                        This Amendment shall become effective on October 27,
2000.
