                              VMARK STOFTWARE, Inc.

                                    Amendment
                                       To
                             1986 Stock Option Plan


The plan is amended, effective January 28, 1997, so that Section 8 (g) shall
read in its entirety as follows:

(g)  TERMINATION OF OPTIONS. Each option shall terminate and may no longer be
     exercised if the optionee ceases for any reason to be neither an employee
     of nor consultant to the Company, or its parent or a subsidiary, in
     accordance with the following provisions:

          (i) if the optionee's relationship shall have been terminated by
              resignation or other voluntary action, or shall have been
              terminated involuntarily for cause, the option shall terminate and
              may no longer be exercised:
         (ii) if the optionee's relationship shall have been terminated for any
              reason other than cause, resignation or other voluntary action
              before he is eligible to retire, disability, or death, he may at
              any time within a period of three (3) months after such
              termination exercise his option to the extent that the option was
              exercisable by him on the date of such termination;
        (iii) if the optionee's relationship shall have been terminated because
              of disability within the meaning of Section 22 (e) (3) of the
              Code, he may at any time within a period of one (1) year after
              such termination exercise his option to the extent that the option
              was exercisable by him on the date of such termination; and
         (iv) if the optionee dies at a time when he might have exercised the 
              option, then his estate, personal representative or beneficiary 
              to whom it has been transferred pursuant to Paragraph 8 
              (f) hereof may at any time within a period of one (1) year after
              the optionee's death exercise the option to the extent the
              optionee might have exercised it at the time of his death;

provided, however, that no option may be exercised to any extent by anyone after
the date of expiration of the option.
