SAFE HARBOR STATEMENT UNDER THE PRIVATE SECURITIES LITIGATION REFORM ACT OF
1995:

This release may contain forward-looking statements based on our current
expectations, estimates and projections about our industry, management's
beliefs, and certain assumptions made by us. Words such as "anticipates,"
"expects," "believes," "may," "will" and similar expressions are intended to
identify forward-looking statements. These statements are not guarantees of
future performance and are subject to certain risks, uncertainties and
assumptions that are difficult to predict. Therefore, our actual results could
differ materially and adversely from those expressed in any forward-looking
statements as a result of various factors.

Important factors that may cause such a difference for Quest Software include,
but are not limited to, variations in the size and timing of customer orders;
dependence on Oracle's technologies; vulnerability to direct competition with
Oracle; strains placed on the Company as a result of past and future growth;
significant increases in operating expenses in the foreseeable future;
disruptions caused by acquisitions of companies and/or technologies; the
exposure to risk from our international operations; unanticipated year 2000
issues; and the need to attract and retain qualified personnel.

Our recent filing on Form S-1 and forthcoming Annual Reports on Form 10-K,
Quarterly Reports on Form 10-Q, and other Securities and Exchange Commission
filings discuss some of the important risk factors that may affect our business,
results of operations and financial condition. We undertake no obligation to
revise or update publicly any forward-looking statements for any reason.
