Dot Hill Reviewing Stock Option Practices
Second Quarter Form 10-Q Filing Delayed

CARLSBAD, Calif. — August 10, 2006 — Dot Hill Systems Corp. (NASDAQ:HILL) today announced that, in response to recently reported industry issues around option pricing, its Audit Committee, which is comprised of independent directors, has begun a self-initiated review of the company’s historical stock option grant practices and related accounting. This review is proactive and voluntary and was initiated in connection with Dot Hill’s filing of its Quarterly Report on Form 10-Q for the three months ended June 30, 2006. The company has reviewed its option grant practices dating back to the company’s merger with Artecon, Inc. in 1999 and has identified certain miscellaneous discrepancies relating to its option grant practices during the 2000 through 2003 fiscal years. Based on a preliminary review, the company believes that the cumulative impact of all such discrepancies is an understatement of compensation expense of less than $500,000. At this time, the Audit Committee is in the final stages of its review but has not reached final conclusions about the company’s stock option practices and the related accounting treatment. Until the Audit Committee’s review is complete, Dot Hill will be unable to complete and file its Quarterly Report on Form 10-Q for the three months ended June 30, 2006 and Dot Hill cannot be certain that it won’t identify additional discrepancies. Dot Hill intends to file its Quarterly Report on Form 10-Q as soon as practicable after the completion of the Audit Committee’s review. Dot Hill will not be able to comment on these matters until after the Audit Committee has completed its review.
