SpaceDev, the world's first commercial space exploration company, has acquired exclusive rights to intellectual property including the three patents originally issued to American Rocket Company (Amroc) for their hybrid rocket motor technology.

In addition, SpaceDev has acquired exclusive possession of and access to a

large quantity of Amroc engineering documents, plans, designs, test

results, manufacturing data, and other materials related to the rocket

motors and Amroc launch vehicles.

"We believe this technology could be useful in a wide variety of

commercial launch vehicle applications," said Jim Benson, president and

chairman of SpaceDev. "Hybrid rocket technology is relatively simple,

environmentally cleaner than most propulsion systems, non-explosive and

less expensive to manufacture. Furthermore, it is easily transported,

throttleable, restartable, and scalable."

Benson noted that hybrid rocket technology has many potential markets,

some of which could be internally useful to SpaceDev and its subsidiaries

in the future, and some of which could become products for sale to

commercial and government customers.

Hybrid rocket motor products could include: small and large boosters for

use in sounding rocket applications, university class satellite launches

and LEO constellation launches; boosters for sale as main propulsion

systems for external customers; strap-ons for expendable and reusable

launch vehicles; smaller specialized motors for use in upper stages; and

for complete launch systems.

Integrated Space Systems (ISS), a wholly owned subsidiary of SpaceDev,

spent several months studying and analyzing original Amroc engineering and

test result documents. The documents were generated from years of Amroc

testing and improvements, and rocket motor test firings. ISS engineers

concluded that Amroc had done excellent engineering, and had brought the

technology close to commercial viability.

"Hybrid rockets combine a liquid oxidizer and solid fuel (therefore

hybrid) into a rocket motor," said Phil Smith, Chief Operating Officer

of SpaceDev. "Because rocket motors or engines form a large part of the

total cost of any launch vehicle, controlling this fundamental underlying

technology could be key to developing low cost launch systems."

In the agreement, SpaceDev is granted the exclusive world wide license

rights for the technology for a minimum of five years. If SpaceDev is

successful in developing a commercial market for the hybrid rocket

technology, it will have the rights to purchase the technology over the

next five years in exchange for discounted warrants for the purchase of

SpaceDev common stock. The warrants would be issued in relation to sales

of the rocket technology and the maximum dilution will not exceed three

million shares. If SpaceDev is not successful in developing a commercial

market for the technology, the company will return the technology and have

no further obligation for the issuance of additional warrants.

Mr. Benson added, "The agreement is extremely fair for both SpaceDev and

the owner of the technology as it allows for both to share in the success

of the technology as may be further developed and marketed by SpaceDev."

SpaceDev, the world's first commercial space exploration and development

company, intends to launch the first privately financed spacecraft to land

on another planetary body. SpaceDev is offering for sale rides for

scientific instruments to governments and companies to transport their

instruments and experiments through deep space to a near Earth asteroid.

SpaceDev intends to sell the data acquired by its instruments as

commercial products. Colorado-based SpaceDev has offices in San Diego, CA

and Washington, DC.
