          Qualstar Reports Fiscal 2006 Second Quarter Results

   SIMI VALLEY, Calif.--(BUSINESS WIRE)--Feb. 2, 2006--Qualstar(R)
Corporation (Nasdaq:QBAK), a manufacturer of automated tape storage
solutions, today reported financial results for the second quarter of
fiscal 2006 ended December 31, 2005.

   Fiscal 2006 Second Quarter Financial Results

   Revenues for the second quarter of fiscal 2006 were $5.7 million,
compared to $6.4 million for the same quarter of the prior year. The
decrease in revenues was due primarily to an approximate $1.0 million
decline in sales of tape libraries and tape drives in the current
quarter compared to last year. This resulted from lower sales of tape
libraries and drives incorporating AIT, SAIT and SDLT tape technology,
partially offset by higher sales of tape libraries and drives
incorporating LTO tape technology. Partially offsetting the decline in
sales of tape libraries and drives were increased sales of power
supplies and tape media. Gross margin in the fiscal 2006 second
quarter was 33.8 percent, compared to 36.2 percent in the year-ago
quarter. The decline in gross margin was primarily related to a change
in product mix, increased competitive pricing pressures and lower
overhead absorption.
   Research and development expenses for the second quarter of fiscal
2006 were $762,000, or 13.4 percent of revenues, compared to $865,000,
or 13.5 percent of revenues, for the year-ago quarter. The decrease in
research and development expenses was due primarily to lower
compensation expenses, prototype costs and consulting fees. Sales and
marketing expenses in the 2006 fiscal second quarter were $715,000, or
12.6 percent of revenues, compared to $868,000, or 13.6 percent of
revenues, in the same quarter last year. The decrease in sales and
marketing expenses resulted primarily from lower compensation expenses
due to fewer employees (a temporary condition), and reduced
advertising and promotion expenses. General and administrative
expenses in the second quarter of fiscal 2006 were $900,000, or 15.8
percent of revenues, compared to $1.1 million, or 17.8 percent of
revenues, for the second quarter of fiscal 2005. The decrease in
general and administrative expenses was due primarily to lower legal
and accounting expenses and reduced bad debt expenses.
   Qualstar reported a loss from operations of $455,000 in the second
quarter of fiscal 2006, compared to a loss from operations of $558,000
for the second quarter of fiscal 2005. The Company reported a net loss
of $189,000, or $(0.02) per basic and diluted share, for the second
quarter of fiscal 2006, compared with a net loss of $347,000, or
$(0.03) per basic and diluted share, for last year's second quarter.
   In accordance with the Share-Based Payment rules (SFAS 123(R))
issued by the Financial Accounting Standards Board, which became
applicable to Qualstar beginning July 1, 2005, Qualstar reported
stock-based compensation expense of $37,000 in the second quarter of
fiscal 2006, compared to $0 in the comparable quarter in fiscal 2005.
   Cash, cash equivalents and marketable securities were $33.8
million at December 31, 2005, compared with $34.1 million at June 30,
2005. Days sales outstanding (DSOs) were approximately 49 days at
December 31, 2005, compared to approximately 48 days at June 30, 2005.
Inventory turns were 2.1 times on an annualized basis for the period
ended December 31, 2005, compared to 2.5 times on an annualized basis
for the period ended June 30, 2005.
   "Our business remained relatively stable this quarter compared to
the first fiscal quarter of this year," said William J. Gervais,
president and chief executive officer of Qualstar. "LTO-based library
sales grew once again as the result of increasing customer demand for
this technology, and our power supply business showed continued
strength both sequentially and compared to last year's second quarter.
   "We are performing continuous qualification testing of our new XLS
enterprise-class library and anticipate shipping our first production
units in the fourth quarter of fiscal 2006. At the same time, we've
released a second, smaller XLS model to pilot production in response
to feedback from some of our key resellers. We believe the large
market for this next generation product line is significant and that
our high-efficiency, low-cost offering will be a welcome addition in
the storage arena," said Mr. Gervais.

   Fiscal 2006 Six-Month Financial Results

   Qualstar reported revenues of $11.8 million for the first six
months of fiscal 2006, compared with $12.7 million for the first six
months of fiscal 2005. The Company's net loss for the first six months
of fiscal 2006 was $400,000, or $(0.03) per basic and diluted share,
compared with a net loss of $583,000, or $(0.05) per basic and diluted
share, in the first six months of fiscal 2005.
