POWAY, Calif. — Jan. 14, 2000 — SpaceDev Inc. the world’s first commercial space
exploration and development company, and Space Innovations Limited (SIL), a wholly owned SpaceDev subsidiary in
Newbury, England, today announced that SIL management has reacquired the company from SpaceDev.

Commenting on the decision, SpaceDev Chairman Jim Benson stated: “During the past year it became clear to the boards of
SPDV and SIL that continued joint operations was not of sufficient long-term benefit to either firm, due primarily to the stringent
U.S. State Department restrictions on the transfer of technology-related information implemented about a year ago. At times we
found it difficult to discuss basic marketing strategies or product enhancement plans with our own employees.”

Professor Leonard Culhane, chairman of SIL, said: “We all thought at the time that this acquisition would be synergistic and
would benefit both firms, but the environment changed unexpectedly. We look forward now to assisting SpaceDev as a
customer rather than one of its subsidiaries.”

In October 1998, SpaceDev acquired 100 percent of SIL via a stock-exchange agreement. The SIL acquisition was one of
several strategic moves made by SpaceDev during the past 18 months to position it as a worldwide, integrated provider of
affordable, reliable space missions involving small satellites. The decision to rescind the merger agreement was made final on
Dec. 17, 1999. Terms of the amicable separation agreement include a re-exchange of common stock and Culhane relinquishing
his seat on SpaceDev’s board.
