ITEM  1.01.  ENTRY  INTO  A  MATERIAL  DEFINITIVE  AGREEMENT.

     On  September  8,  2005, SpaceDev, Inc. ("SpaceDev") made a secured loan in
the   principal   amount  of  $1.2   million  to  Starsys  Research  Corporation
("Starsys"),  a  design,  engineering,  and  manufacturing  company  located  in
Boulder,  Colorado  that  provides mechanical systems to the aerospace industry.
The  loan  accrues  interest at 8% per annum and matures on December 31, 2005 or
earlier  in  certain  circumstances.  No  principal or interest payments are due
before  maturity.  The  maturity  date may be accelerated upon the occurrence of
certain  events of default. The loan is secured by a security interest in all of
the  assets  of  Starsys, subject to an intercreditor agreement with Vectra Bank
Colorado,  National  Association  ("Vectra"),  described  below.

     In  connection  with  making the loan, SpaceDev entered into an exclusivity
agreement  with  Starsys which provides that Starsys will not discuss a material
sale  of  its  assets,  a  material  sale  of  its  stock,  a merger, or similar
transaction  with any other party until October 31, 2005. Prior to completion of
the loan described above, SpaceDev and Starsys entered into a non-binding letter
of  intent  concerning  a transaction of the nature described in the exclusivity
agreement. The structure and economic terms of a potential transaction, however,
remain  subject  to  further negotiations and due diligence by both parties, and
neither  party  is  obligated  to  proceed  with  a potential transaction on any
particular  terms  or  at  all.

     In  addition,  Starsys has agreed to pay SpaceDev a placement agent fee and
to  reimburse  SpaceDev's  expenses  in  the  aggregate amount of $120,000. This
amount was capitalized and added to the principal balance of the note evidencing
the loan. SpaceDev has agreed to forgive this amount if SpaceDev unilaterally or
with  the agreement of Starsys withdraws from negotiations regarding a potential
transaction  between  the parties, if such a potential transaction closes before
October  31,  2005  or  if  the  parties  cannot  obtain  necessary governmental
approvals  for  such  a  potential  transaction.

     Starsys must use the proceeds of the loan to make a progress payment on the
outstanding principal balance of certain loans in the aggregate principal amount
of  approximately  $5.8  million  made  by  Vectra  to  Starsys  under a secured
revolving  credit  and  term  loan  agreement,  which  payment  was  due under a
forbearance  agreement  between  Starsys  and  Vectra.

     In  connection  with the loan by SpaceDev to Starsys, SpaceDev, Starsys and
Vectra  also  entered  into  an  intercreditor agreement, under which Vectra and
SpaceDev  agree  to the allocation of any payments from Starsys or proceeds from
collateral  that  SpaceDev or Vectra receives related to their respective loans,
other  than  regular  payments  of principal and interest. These funds are first
used  for collection and insurance expenses, next to repay any funds advanced by
Vectra  after  September  8,  2005,  and next pro rata among Vectra and SpaceDev
based  on  the  respective   outstanding   principal,  due  interest  and  other
liabilities  outstanding  under  the respective loan documents. Vectra retains a
first  priority  security  interest  in all of the assets of Starsys and acts as
SpaceDev's  collateral  agent.  Under  the  intercreditor  agreement, so long as
Vectra  is  the collateral agent, SpaceDev may not take any action to collect on
its  loan  to  Starsys  except  to file a proof of claim in a Starsys bankruptcy
proceeding  or  to  request  Vectra, as its collateral agent, to take collection
efforts  after  SpaceDev's  loan  becomes  due. SpaceDev may terminate Vectra as
collateral  agent  only if Vectra fails to accelerate SpaceDev's loan to Starsys

                                     PAGE

by January 31, 2006 or refuses to foreclose on SpaceDev's loan by or after March
31,  2006.  SpaceDev may not pledge, sell or otherwise transfer its loan without
Vectra's  consent.  There can be no assurance that Starsys will be able to repay
the  loan  or  that SpaceDev can otherwise recover on its investment in Starsys.
