ITEM 5.  OTHER EVENTS

        On November 2, 1999, Quest Software, Inc. ("Quest") entered into an
Agreement and Plan of Merger (the "Merger Agreement") by and among Quest, Quest
Acquisition Corporation ("Sub"), MBR Technologies, Inc., a California
corporation ("MBR"), John Rocha, Joseph F. Brusatto, Michael Q. Mai and Vicente
Perez de Tudela (collectively, the "Shareholders"). Under the Merger Agreement,
Sub will be merged with and into MBR, with MBR as the surviving corporation in
the merger. MBR will thereby become a wholly-owned subsidiary of Quest. The
merger is to be effected through the issuance of an aggregate of $10 million of
shares of Quest Common Stock and $1.5 million in cash (subject to reduction for
certain transaction and other expenses) in exchange for all of the outstanding
capital stock of MBR. The per share price for purposes of determing the number
of shares of Quest Common Stock that will be issued in the merger will be based
on the average of the closing prices of the Quest Common Stock on the Nasdaq
National Market for the five trading days ending one day prior to the closing
date of the merger. The amount of such consideration was determined based upon
arm's-length negotiations between Quest and MBR. The consummation of the merger
is subject to the satisfaction of certain conditions.

        A copy of the press release announcing the merger agreement with MBR is
attached hereto as Exhibit 99.1 and incorporated herein by reference.
