         Capstone Turbine Corporation Announces First Quarter
                    Fiscal 2008 Operating Results

   First Quarter Revenue of $5.6 Million; Backlog Increases 6% and
              Inventory Decreases 7% from Prior Quarter


   CHATSWORTH, Calif.--(BUSINESS WIRE)--Aug. 8, 2007--Capstone
Turbine Corporation(R) (www.microturbine.com) (NASDAQ:CPST), reported
operating results for its first quarter ended June 30, 2007 in its
Quarterly Report on Form 10-Q filed with the Securities and Exchange
Commission on August 8, 2007.

   Financial Summary

   Capstone's revenue for the first quarter ended June 30, 2007 was
$5.6 million, a decrease of approximately 14% from the same period
last year. The decline is attributable to lower than expected sales
primarily in the North American and Asian markets.

   Backlog at the end of the first quarter was $5.3 million, an
increase of approximately $0.3 million, or 6% from the prior quarter
but decreased approximately $0.1 million, or 2% from the end of the
prior year comparable quarter.

   The reported gross loss for the first quarter was $2.5 million, or
44% of revenue, compared to $1.2 million, or 19% of revenue from the
same period last year. The increase in gross loss was due to lower
sales of higher margin C-60 series units and lower absorption of
overhead costs into inventory offset by decreased costs for
manufacturing, warranty and inventory charges. During the quarter
inventory decreased $1.6 million or 7% from the prior quarter.

   Research and development costs were $2.7 million for the first
quarter, a decrease of $0.1 million, or 2% from the same period last
year. R&D expenses are reported net of benefits from cost-sharing
programs. There were no such benefits this quarter and $0.5 million
for the same period last year. Overall net expenses were lower
primarily due to lower labor and consulting spending, decreased
development hardware, and reduced facilities expenses.

   Selling, general and administrative costs were $5.9 million for
both the first quarter of fiscal 2008 and the same period last year.
Reduced non-cash stock compensation was offset by increased labor
related costs, professional services, travel, marketing, supplies and
facility maintenance costs.

   Capstone's net loss was $10.4 million, or $0.07 per share, for the
first quarter, an increase of $1.1 million from the $9.3 million loss,
or $0.09 per share, reported for the same period last year.

   Cash balances decreased by $10.1 million during the first quarter
of fiscal 2008. As of June 30, 2007, cash and cash equivalents were
$50.3 million.
