                            CERTIFICATE OF AMENDMENT
                                       OF
                          CERTIFICATE OF INCORPORATION
                                       OF
                           ENCORE COMPUTER CORPORATION

     ENCORE COMPUTER CORPORATION, a corporation organized and existing under and
by virtue of the General Corporation Law of the State of Delaware, DOES HEREBY
CERTIFY:

     FIRST: That the Board of Directors of said corporation, at a meeting duly
held on October 22, 1986, duly adopted the following vote:

     VOTED: That it is hereby proposed and declared advisable that the
certificate of incorporation of this corporation be amended to add a new Article
ELEVENTH to read as follows:

               ELEVENTH: A Director of the corporation shall not be personally
               liable to the corporation or its stockholders for monetary
               damages for breach of fiduciary duty as a director, except that
               this Article ELEVENTH shall not eliminate or limit a Director's
               liability (i) for any breach of the director's duty of loyalty to
               the corporation or its stockholders; (ii) for acts or omissions
               not in good faith or which involve intentional misconduct or a
               knowing violation of law; (iii) under Section 174 of the Delaware
               General Corporation Law; or (iv) for any transaction from which
               the director derived an improper personal benefit. If the
               Delaware General Corporation Law is amended after approval by the
               stockholders of this Article ELEVENTH to authorize corporate
               action further eliminating the personal liability of a Director,
               then the liability of a Director of the corporation shall be
               eliminated or limited to the fullest extent permitted by the
               Delaware General Corporation Law, as so amended from time to
               time.

               Any repeal or modification of this Article ELEVENTH shall not
               increase the personal liability of any Director of this
               corporation for any act or occurrence taking place prior to such
               repeal or modification, or otherwise adversely affect any right
               or protection of a Director of the corporation existing at the
               time of such repeal or modification.
