QUALSTAR ANNOUNCES STOCK REPURCHASE PROGRAM

SIMI VALLEY, Calif., February 12, 2003 — Qualstar^® Corporation (Nasdaq: QBAK), a leading manufacturer of automated tape storage solutions, announced today that its Board of Directors  has authorized a repurchase of up to 500,000 shares of the company’s common stock.

Shares will be repurchased from time to time as market conditions warrant through open market transactions, block purchases, private transactions or other means.  The share repurchase will be funded by available working capital.  As of December 31, 2002, Qualstar had in excess of $35 million in cash, cash equivalents and marketable securities, and approximately 12.7 million shares outstanding.  No time limit has been set for the completion of the stock repurchase program and it may be discontinued at any time.

“We believe that our stock represents excellent long-term value,” said William J. Gervais, chief executive officer and president.  “A repurchase reduces the dilutive impact of shares issued for options and reflects our confidence in the company’s business strategy, cash flow generation and growth prospects.”
