QUEST SOFTWARE ANNOUNCES STOCK REPURCHASE PROGRAM

ALISO VIEJO, Calif., Mar. 6, 2009 – Quest Software, Inc. (Nasdaq: QSFT) ) today announced that its board of directors has authorized a stock repurchase of up to $100 million of its common stock. Any stock repurchases may be made through open market and privately negotiated transactions, at times and in such amounts as management deems appropriate, including pursuant to one or more Rule 10b5-1 trading plans. Rule 10b5-1 permits Quest to establish, while not in possession of material nonpublic information, prearranged plans to buy stock at a specific price in the future, regardless of any subsequent possession of material nonpublic information. The timing and actual number of shares repurchased will depend on a variety of factors including market conditions, corporate and regulatory requirements, and capital availability. The stock repurchase program does not have an expiration date and may be limited or terminated at any time without prior notice. The board of directors conditioned its approval of the stock repurchase on Quest entering into a voting agreement with Vincent C. Smith, Quest’s executive chairman of the board, whereby Mr. Smith would agree to vote any shares of Quest common stock owned by him that represent greater than 35% of our outstanding shares of common stock in the same proportion as all of the shares of Quest common stock actually voted on any matter presented to our shareholders. Mr. Smith currently has beneficial ownership of approximately 32% of our common stock.

Quest also announced that on February 13, 2009, Quest’s shareholders approved the principal terms of the Agreement and Plan of Merger between Quest and a wholly-owned Delaware subsidiary of Quest pursuant to which Quest will effect its reincorporation from California to Delaware. Quest expects to complete the reincorporation within the next thirty days.
