                                       OF
                          CERTIFICATE OF INCORPORATION
                                       OF
                               EMULEX CORPORATION

        Emulex Corporation, a corporation organized and existing under and by
virtue of the General Corporation Law of the State of Delaware (the
"Corporation"), does hereby certify as follows:

        FIRST: That at a meeting of the Board of Directors of the Corporation,
resolutions were duly adopted setting forth a proposed amendment of the
Certificate of Incorporation of the Corporation, declaring said amendment to be
advisable and calling a special meeting of the stockholders of the Corporation
for consideration thereof. The resolution setting forth the proposed amendment
is as follows:

        RESOLVED, that, subject to obtaining the requisite approval of the
        stockholders of the Corporation, Article IV of the Corporation's
        Certificate of Incorporation be amended, without effect upon any stock
        designation heretofore filed, to read as follows:

                                  "ARTICLE IV
                            Authorized Capital Stock

             The corporation is authorized to issue two classes of capital
        stock, designated Common Stock and Preferred Stock. The amount of total
        authorized capital stock of the corporation is 21,000,000 shares,
        divided into 20,000,000 shares of Common Stock, par value $.20 per
        share, and 1,000,000 shares of Preferred Stock, par value $.01 per
        share. Upon the effectiveness of the Amendment, each two outstanding
        shares of Common Stock, par value $.10 per share, shall be reclassified,
        converted and changed into one share of Common Stock, par value $.20 per
        share. Each holder of Common Stock who would otherwise be entitled to
        receive a fractional share shall instead be entitled to receive cash for
        such fractional share, the amount of cash to be determined on the basis
        of the average closing price of the Common Stock on the NASDAQ National
        Market System for the ten trading days immediately preceding the
        effective date of this Amendment.

             The shares of Preferred Stock may be issued from time to time in
        one or more series. The board of directors is hereby authorized to fix
        by resolution or resolutions the designations and the powers,
        preferences and relative, participating, optional or other special
        rights, and qualifications, limitations 
   6
        or restrictions of any series of shares of Preferred Stock, including
        without limitation the dividend rate, conversion rights, redemption
        price and liquidation preference, of any such series, and to fix the
        number of shares constituting such series, and to increase or decrease
        the number of shares of any such series (but not below the number of
        shares thereof then outstanding). In case the number of shares of any
        such series shall be so decreased, the shares constituting such decrease
        shall resume the status which they had prior to the adoption of the
        resolution or resolutions originally fixing the number of shares of such
        series."

        SECOND: That thereafter, pursuant to resolutions of its Board of
Directors, a special meeting of the stockholders of the Corporation was duly
called and held, upon notice in accordance with Section 222 of the General
Corporation Law of the State of Delaware at which meeting the necessary number
of shares as required by statute were voted in favor of the amendment.

        THIRD: That said amendment was duly adopted in accordance with the
provisions of Section 242 of the General Corporation Law of the State of
Delaware. 

        IN WITNESS WHEREOF, the Corporation has caused this certificate to be
signed by Paul F. Folino, its President and Chief Executive officer, and Walter
J. McBride, its Senior Vice President, Chief Financial Officer and Secretary,
this 24th day of February, 1994.
