SpaceDev, Inc.
, a leading provider of microsatellites and hybrid
propulsion technology, today reported financial results for the second quarter
of 2003.

Net sales for the six-month period ending June 30, 2003 were approximately
$1.3 million as compared to net sales of approximately $1.8 million for the
same six-month period in 2002. Sales in 2003 were comprised of approximately
$397,000 from a proprietary propulsion program, $331,000 from the CHIPSat
program, $250,000 from a completed Missile Defense Agency (MDA) project,
$242,000 from Air Force Research Laboratory (AFRL) projects and approximately
$67,000 from all other programs. In the first six-months of 2002, sales were
comprised of approximately $806,000 from the CHIPSat program, $807,000 from a
proprietary propulsion program and $199,000 from all other programs.

During the six-months ending June 30, 2003, the Company incurred a net
loss of approximately $918,000, or 71% of net sales, compared to a net loss of
approximately $117,000, or 6% of net sales, for the same six-months ending in
2002. The increase in the net loss was primarily due to a reduction in
revenues attributable to the substantial completion of the CHIPSat program,
and to deferred or delayed new programs and an increase in operating expenses
of approximately $976,000, or 76% of net sales. Operating expenses for the
six-months ending June 30, 2002 were approximately $368,000, or 20% of net
sales.

Operating expenses for the second quarter of 2003 included:

— general and administrative expenses (which increased approximately
$226,000 due to an increase in rent expense, amortization of
previously capitalized technology costs, and fees related the
Company’s revolving credit facility with Laurus Master Fund, Ltd.
announced in a Form 8-K filed June 18, 2003;

— increased marketing and sales expenses of approximately $130,000
(primarily due to the expansion of the Company’s marketing and
product development department); and,

— research and development expenses of approximately $252,000, of
which approximately $171,000 was in connection with our hybrid
rocket propulsion design and the remaining $81,000 was part of the
Company’s satellite bus design and development.

Recent Events

On July 15, 2003, SpaceDev announced that it had been awarded a contract
to develop micro- and nano-satellite bus and subsystem designs from the AFRL
Small Business Innovation Research (SBIR) program, which will enable SpaceDev
to explore the further miniaturization of its unique and innovative microsat
subsystems. Other recent awards include a second SBIR contract by the AFRL to
design and begin the development of the SpaceDev Streaker(TM) small launch
vehicle (SLV) (announced on July 18) as well as a second contract by the
Missile Defense Agency (MDA) to explore the use of microsatellites in national
missile defense (announced on July 24). On July 24, SpaceDev was awarded a
commercial study by Lunar Enterprise of California (LEC) for a first phase
project to begin developing a conceptual mission and spacecraft design for a
lunar lander program.
