Board of Directors adopted pursuant to this Article IV.

                                   ARTICLE V

     Effective as of the time at which Hewlett-Packard Company, a Delaware
corporation, and its affiliates shall cease to be the beneficial owner of an
aggregate of at least a majority of the then outstanding shares of Common Stock
(the "Trigger Date"), 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.  Effective as of the Trigger Date, except as otherwise
required by law and subject to the rights of the holders of any class or series
of stock having a preference over the Common Stock as to dividends or upon
liquidation, special meetings of stockholders of the Corporation for any purpose
or purposes may be called only by the Board of Directors or by the Chairman of
the Board of Directors of the Corporation and, effective as of the Trigger Date,
any power of stockholders to call a special meeting is specifically denied.  No
business other than that stated in the notice shall be transacted at any special
meeting.

     The Corporation is to have perpetual existence.

                                  ARTICLE VII

     For the management of the business and for the conduct of affairs of the
Corporation, and in further definition, limitation and regulation of powers of
the Corporation, of its directors and of its stockholders or any class thereof,
as the case may be, it is further provided that:

                                      -3-


          A.    The management of the business and the conduct of the affairs of
the Corporation shall be vested in its Board of Directors.  The number of
directors of this Corporation shall be fixed and may be changed from time to
time by resolution of the Board of Directors.

          B.    The Directors, other than those who may be elected by the
holders of any class or series of stock having a preference over the Common
Stock as to dividends or upon liquidation, shall be classified, with respect to
the time for which they severally hold office, into three classes, as nearly
equal in number as possible, one class to be originally elected for a term
expiring at the annual meeting of stockholders to be held in 2000, another class
to be originally elected for a term expiring at the annual meeting of
stockholders to be held in 2001, and another class to be originally elected for
a term expiring at the annual meeting of stockholders to be held in 2002, with
each class to hold office until its successor is duly elected and qualified.  At
each succeeding annual meeting of stockholders, directors elected to succeed
those directors whose terms then expire shall be elected for a term of office to
expire at the third succeeding annual meeting of stockholders after their
election.

          C.    Notwithstanding the foregoing provisions of this Article VII,
each director shall serve until his or her successor is duly elected and
qualified or until his or her death, resignation or removal.  No decrease in the
number of directors constituting the Board of Directors shall shorten the term
of any incumbent director.

          D.    Any vacancies on the Board of Directors resulting from death,
resignation, disqualification, removal, or other causes unless the Board of
Directors determines by resolution that any such vacancies or newly created
directorships shall be filled by stockholders, and except as otherwise provided
by law, shall be filled only by the affirmative vote of a majority of the
remaining directors then in office, even though less than a quorum of the Board
of Directors and not by the stockholders.

          E.    In furtherance and not in limitation of the powers conferred by
the laws of the State of Delaware, the Board of Directors is expressly
authorized to make, alter, amend or repeal the Bylaws of the Corporation.

          F.    The directors of the Corporation need not be elected by written
ballot unless the Bylaws of the Corporation so provide.

          G.    Advance notice of stockholder nomination for the election of
directors and of any other business to be brought by stockholders before any
meeting of the stockholders of the Corporation shall be given in the manner
provided in the Bylaws of the Corporation.

                                 ARTICLE VIII

     A.   To the fullest extent permitted by the Delaware General Corporation
Law as the same exists or as may hereafter be amended, no director of the
Corporation shall be personally liable to the Corporation or its stockholders
for monetary damages for breach of fiduciary duty as a director.

                                      -4-


     B.  The Corporation may indemnify to the fullest extent permitted by law
any person made or threatened to be made a party to an action or proceeding,
whether criminal, civil, administrative or investigative, by reason of the fact
that he, his testator or intestate is or was a director, officer or employee of
the Corporation or any predecessor of the Corporation or serves or served at any
other enterprise as a director, officer or employee at the request of the
Corporation or any predecessor to the Corporation.

     C.  Neither any amendment nor repeal of this Article VIII, nor the adoption
of any provision of this Corporation=s Certificate of Incorporation inconsistent
with this Article VIII, shall eliminate or reduce the effect of this Article
VIII, in respect of any matter occurring, or any action or proceeding accruing
or arising or that, but for this Article VIII, would accrue or arise, prior to
such amendment, repeal or adoption of an inconsistent provision.

                                  ARTICLE IX

     Meetings of stockholders may be held within or without the State of
Delaware, as the Bylaws may provide.  The books of the Corporation may be kept
(subject to any provision contained in the laws of the State of Delaware)
outside of the State of Delaware at such place or places as may be designated
from time to time by the Board of Directors or in the Bylaws of the Corporation.

                                      -5-


                                   ARTICLE X

     Except as provided in Article VIII above, the Corporation reserves the
right to amend, alter, change or repeal any provision contained in this
Certificate of Incorporation, in the manner now or hereafter prescribed by the
laws of the state of Delaware, and all rights conferred upon stockholders herein
are granted subject to this reservation.  Notwithstanding anything contained in
this Certificate of Incorporation to the contrary, the affirmative vote of the
holders of at least 80% of the voting power of all shares of the Corporation
entitled to vote generally in the election of directors (the "Voting Stock")
then outstanding, voting together as a single class shall be required to alter,
amend, adopt any provision inconsistent with or repeal Article V or VII or this
sentence.
