                            CERTIFICATE OF AMENDMENT
                                     TO THE
                          CERTIFICATE OF INCORPORATION
                                       OF
                           DELL COMPUTER CORPORATION


Dell Computer 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:

FIRST:      The Board of Directors of the Corporation, acting at a meeting duly
            called and held on April 16, 1991, did duly consent to, approve and
            adopt the following resolution:

            NOW THEREFORE BE IT RESOLVED that, the following amendments to the
            Corporation's Certificate of Incorporation shall be put to a vote
            of the stockholders of the Corporation and if approved by the vote
            of a majority of the outstanding shares of the stock of the
            Corporation, the Certificate of Incorporation shall be so amended:

            1.       Present Article Seventh shall be deleted in its entirety
                     and replaced  with the following:

                     SEVENTH:  The directors shall be classified, with respect
                     to the time for which they severally hold office, into
                     three classes, as nearly equal in number as possible, as
                     shall be provided in the manner specified in the bylaws of
                     the Corporation, one class to be originally elected for a
                     term expiring on the annual meeting of stockholders to be
                     held in 1992, another class to be originally elected for a
                     term expiring at the annual meeting of stockholders to be
                     held in 1993, and another class to be originally elected
                     for a term expiring at the annual meeting of stockholders
                     to be held in 1994, with each class to hold office until
                     its successor is elected and qualified.  At each annual
                     meeting of the stockholders of the Corporation, the
                     successors of the class of directors whose term expires at
                     that meeting shall be elected to hold office for a term
                     expiring at the annual meeting of stockholders held in the
                     third year following the year of their election.

                     Any director may be removed from office, but only for
                     cause, by a vote of the holders of a majority of the
                     shares then issued and outstanding.  Cause shall mean
                     willful and gross misconduct by the director that is
                     materially adverse to the best interests of the
                     Corporation, as determined con-





                                       1
   2
                     clusively by a majority of the disinterested directors of 
                     the Corporation.

                     Vacancies and newly created directorships resulting from
                     any increase in the authorized number of directors may be
                     filled by a majority of the directors then in office,
                     although less than a quorum, or the sole remaining
                     director, and shall not be filled by the stockholders; any
                     director so chosen shall hold office until the next
                     election of the class for which such director shall have
                     been chosen, and until his successor shall be duly elected
                     and shall qualify, unless sooner displaced.

                     Notwithstanding anything contained in this Certificate of
                     Incorporation to the contrary, the affirmative vote of the
                     holders of at least 66 2/3 % of the shares of the
                     Corporation's voting stock issued and outstanding shall be
                     required to alter, amend, adopt any provision inconsistent
                     with or repeal this Article Seventh.

            2.       Present Article Eighth shall be deleted and replaced in
                     its entirety with the following:

                     EIGHTH:  Any action required or permitted to be taken by
                     the stockholders of the Corporation must be effected at a
                     duly called annual or special meeting of such holders and
                     may not be effected by any consent in writing by such
                     holders.  Notwithstanding anything contained in this
                     Certificate of Incorporation to the contrary, the
                     affirmative vote of the holders of at least 66 2/3 % of
                     the shares of the Corporation's stock issued and out
                     standing shall be required to alter, amend, adopt any
                     provision inconsistent with or repeal this Article Eighth.

            3.       Present Article Ninth shall be renumbered as Article
                     Tenth, present Article Tenth renumbered as Article
                     Eleventh and the following Article Ninth added:

                     authorized to adopt, amend or repeal the by-laws of the
                     Corporation or adopt new by-laws, without any action on
                     the part of the stockholders, by the vote of a majority of
                     the directors; provided, however, that no such adoption,
                     amendment, or repeal shall be valid with respect to by-law
                     provisions which have been adopted, amended, or repealed
                     by the stockholders; and further provided, that by-laws
                     adopted or amended by the Directors

                     provision inconsistent therewith shall be adopted by the
                     stockholders without the affirmative vote of the holders
                     of at least 66 2/3% of the Corporation's voting stock
                     issued and outstanding.  Not withstanding anything
