Item 5.   Other Events
          ------------

     International Network Services ("INS") is restating the following
information to give retroactive effect to its acquisition (the "Acquisition") of
VitalSigns Software, Inc. ("VitalSigns"), which was effective as of November 20,
1998 and accounted for as a pooling of interests: (i) Consolidated Financial
Statements at June 30, 1997 and 1998 and for each of the three years in the
period ended June 30, 1998, (ii) unaudited Consolidated Financial Statements at
September 30, 1998 and for the fiscal quarters ended September 30, 1998 and
1997, and (iii)  Management's Discussion and Analysis of Financial Condition and
Results of Operations which relates to the foregoing financial statements.  Such
information is attached hereto as Exhibit 99 and incorporated herein by this
reference.

     Generally accepted accounting principles proscribe giving effect to a
consummated business combination accounted for by the pooling of interests
method in financial statements that do not include the date of consummation.
These financial statements do not extend through the date of consummation.
However, they will become the historical consolidated financial statements of
INS and its subsidiaries after financial statements covering the date of
consummation of the business combination are issued.
