                Capstone Turbine Corporation Announces
             Third Quarter Fiscal 2007 Operating Results

     Revenue of $5.7 Million up 97% from Prior Quarter. Gross Loss
                            Improves to 8%.


    CHATSWORTH, Calif.--(BUSINESS WIRE)--Feb. 9, 2007--Capstone
Turbine Corporation (Nasdaq:CPST) (www.microturbine.com) reported
operating results for its third quarter ended December 31, 2006 in its
Quarterly Report on Form 10-Q filed with the Securities and Exchange
Commission on February 9, 2007.

    Financial Summary

    Capstone's backlog at the end of the third quarter was $8.1
million, an increase of 19% from the prior quarter, although decreased
over 19% from the prior year comparable quarter. "Notably, orders
booked during the third quarter were $5.9 million or 6.2 megawatts
exceeding orders for each of the last five quarters," said Darren
Jamison, Capstone's President and CEO.

    Revenue for the fiscal 2007 third quarter was $5.7 million, an
increase of approximately 97% from the prior quarter and a decrease of
approximately 19% from the prior year comparable quarter.

    The reported gross loss for the third quarter was $0.5 million, or
8% of revenue, improved, when compared to $2.8 million, or 39% of
revenue from the prior year comparable quarter and $2.3 million, or
79% of revenue from the prior quarter. The improvement in the gross
loss and corresponding gross loss percentage reflects higher volume,
improved product mix and decreasing manufacturing expense.

    Research and development costs were $2.0 million for the fiscal
2007 third quarter, an improvement of $1.1 million, or 35%, from the
prior year comparable quarter and $0.6 million, or 23% from the prior
quarter. The improvement was primarily related to reduced payroll,
consulting and development hardware costs as well as increased
contract recoveries.

    Selling, general and administrative costs were $6.4 million for
the fiscal 2007 third quarter, an improvement of $2.6 million, or 29%,
from the prior year comparable quarter, of $9.0 million. The decrease
from the prior year comparable quarter is primarily attributable to
lower marketing, payroll, professional fees and legal settlement costs
offset by approximately $0.3 million of increased non-cash stock
compensation charges related to the Company's adoption of SFAS 123(R).
Selling, general and administrative costs increased $0.3 million, or
5% from the prior quarter. The increase from the prior quarter is due
to executive hiring costs and increased facilities costs offset by
decreased administrative costs associated with our Annual Shareholders
Meeting and Proxy Statement distribution.

    Capstone's net loss was $8.5 million for the fiscal 2007 third
quarter, or $0.08 per diluted common share, an improvement of $1.9
million from the $10.4 million loss, or $0.10 per diluted common
share, reported for the second quarter of fiscal 2007.

    Cash balances decreased by $13.8 million during the third quarter
of fiscal 2007. The cash decrease consisted primarily of the $8.5
million net loss and changes in working capital of $6.1 million. The
changes in working capital were primarily the result of higher
accounts receivable as a result of the increased sales in the quarter
and decreased accounts payable and accrued expenses. As of December
31, 2006, cash and cash equivalents were $25.5 million.

    On January 24, 2007 the company closed its equity offering
announced on January 19, 2007, providing net cash proceeds of
approximately $42.4 million.
