        Capstone Turbine Corporation Announces Second Quarter
                    Fiscal 2007 Operating Results


    CHATSWORTH, Calif.--(BUSINESS WIRE)--Nov. 9, 2006--Capstone
Turbine Corporation (Nasdaq:CPST) (www.microturbine.com) reported
operating results for its second quarter ended September 30, 2006 in
its Quarterly Report on Form 10-Q filed with the Securities and
Exchange Commission on November 9, 2006.

    Financial Summary

    Capstone's revenue for the fiscal 2007 second quarter was $2.9
million, representing a decrease of approximately 48% from the prior
year comparable quarter and a decrease of 55% from the prior quarter.
Product sales to the European and Russian markets declined
approximately $2.3 million from the first quarter, although new orders
of approximately $2.5 million were received from these markets during
the quarter.

    Backlog at the end of the second quarter was $6.8 million, an
increase of over 26% from the prior quarter, although decreased over
45% from the end of the prior year comparable quarter. In October,
after the close of the second quarter, we received a new order for 1.6
megawatts or $1.4 million dollars from our major OEM customer.

    "We are pleased with the traction we have experienced in Europe
and Russia over the past year, despite lower sales this quarter. John
Fink, our Executive Vice President, Sales and Service, is continuing
to build momentum with our relationships in the New York market. We
have increased our commitment to the New York market by expanding our
lease to build out sales and service offices, warehousing,
manufacturing and light component assembly work in Brooklyn," said
Mark Gilbreth, Capstone's Interim President and CEO.

    The reported gross loss for the second quarter was $2.3 million,
or 79% of revenue compared to $1.1 million, or 19% of revenue from the
prior year comparable quarter and $1.2 million, or 19% of revenue from
the prior quarter. The increase in the gross loss and corresponding
decline in the gross loss percentage reflects lower volume and
increased warranty charges.

    Research and development costs were $2.6 million for the fiscal
2007 second quarter, an improvement of $0.1 million, or 5%, from the
prior year comparable quarter and $0.2 million, or 8% from the prior
quarter. The improvement was primarily related to continued lower
spending on development hardware and reduced payroll costs.

    Selling general and administrative costs were $6.1 million for the
fiscal 2007 second quarter, an improvement of $0.7 million, or 11%,
from the prior year comparable quarter, of $6.8 million. The decrease
from the prior year comparable quarter is primarily attributable to
lower payroll and professional fees, offset by approximately $0.2
million of increased non-cash stock compensation charges related to
the Company's adoption of SFAS 123(R). Selling, general and
administrative costs increased $0.1 million, or 2% from the prior
quarter. The increase from the prior quarter is due to slightly
increased sales and marketing expenses and increased administrative
costs associated with our Annual Shareholders Meeting and Proxy
Statement distribution.

    Capstone's net loss was $10.4 million for the fiscal 2007 second
quarter, or $0.10 per diluted common share, an increase of $1.1
million from the $9.3 million loss, or $0.09 per diluted common share,
reported for the first quarter of fiscal 2007.

    Cash balances decreased by $9.4 million during the second quarter
of fiscal 2007. As of September 30, 2006, cash and cash equivalents
were $39.3 million.
