ITEM  1.01.  ENTRY  INTO  A  MATERIAL  DEFINITIVE  AGREEMENT.

     AGREEMENT  AND  PLAN  OF  MERGER  AND  REORGANIZATION

     Overview.  On October 24, 2005, SpaceDev, Inc. ("SpaceDev") entered into an
Agreement and Plan of Merger and Reorganization, which we refer to as the merger
agreement,   with  Starsys   Research   Corporation  ("Starsys"),   a   Colorado
corporation, and Scott Tibbitts, its largest shareholder. Pursuant to the merger
agreement,  Starsys  will  merge  with  and  into  a newly-created, wholly-owned
subsidiary  of  SpaceDev. Holders of Starsys common stock will become holders of
SpaceDev common stock following the merger. The merger agreement is subject to a
number  of  conditions  described  below,  including effectiveness of a Form S-4
registration  statement  and approval of the respective shareholders of SpaceDev
and  Starsys.

     Merger  Consideration.  SpaceDev  will  pay  and  issue  the  following
consideration  at  the  effective  time  of the merger, subject to adjustment as
provided  in  the  merger  agreement:

     -    cash  in  the  aggregate  amount  of  $1,500,000;  and

     -    an  aggregate  number  of shares of SpaceDev common stock equal to the
          quotient of (A) $7,500,000 divided by (B) the greater of (1) $1.40 and
          (2)  the lesser of (x) $1.90 and (y) the volume weighted average price
          of  SpaceDev  common  stock  for  the  preceding  20  trading  days.

Fifty  percent  (50%) of the number of shares of SpaceDev common stock issued at
closing  will  be  deposited  in  escrow  as  security   for  the   payment   of
indemnification  claims  under the merger agreement, which escrow will generally
last  until  ten  (10)  days  following the date of audited financial statements
prepared  for  the  surviving corporation for the fiscal year ending 2006 (i.e.,
approximately  April  2007).

     Following the merger, Starsys shareholders may also be entitled to receive,
based  on  the  achievement  by the surviving corporation of certain performance
criteria  for  each  of  the fiscal years ending December 31, 2005, December 31,
2006  and  December  31, 2007, additional earnout consideration consisting of up
to:

     1.   For the fiscal year ended December 31, 2005, $350,000 in cash and an
          aggregate number of shares of  SpaceDev  common  stock  equal  to  the
          quotient of (A) $3,500,000 divided by (B) the greater of (1) $2.00 and
          (2) the volume weighted average price of SpaceDev common stock for the
          twenty (20) trading days preceding the date of the  audit opinion  for
          the surviving corporation's fiscal year ended December 31, 2005;

     2.   For  the  fiscal year ended December 31, 2006, $350,000 in cash and an
          aggregate  number  of  shares  of  SpaceDev  common stock equal to the
          quotient of (A) $7,500,000 divided by (B) the greater of (1) $2.50 and
          (2) the volume weighted average price of SpaceDev common stock for the
          twenty  (20)  trading days preceding the date of the audit opinion for
          the  surviving corporation's fiscal year ended December 31, 2006; and,

     3.   For  the  fiscal year ended December 31, 2007, $350,000 in cash and an
          aggregate  number  of  shares  of  SpaceDev  common stock equal to the
          quotient of (A) $7,500,000 divided by (B) the greater of (1) $3.00 and
          (2) the volume weighted average price of SpaceDev common stock for the
          twenty  (20)  trading days preceding the date of the audit opinion for
          the  surviving  corporation's  fiscal  year  ended  December 31, 2007.

     If any shares of SpaceDev common stock are payable as earnout consideration
for  the  fiscal  year  ending  December  31, 2005, fifty percent (50%) of those
shares  will  be  deposited  in  the  escrow  described  above.

     Each  outstanding  share  of SpaceDev common stock will remain unchanged in
the  merger.

     Working  Capital Contribution. SpaceDev will contribute $2.5 million to the
working  capital  of  the  surviving  corporation  through  the  end  of  2006.

                                      PAGE

     Treatment  of  Stock Options and Warrants. The holders of options, warrants
and  other  rights to purchase Starsys common stock must exercise such rights on
or  before  the  closing of the merger. Any options, warrants or other rights to
purchase  Starsys  common  stock which are not exercised prior to the closing of
the merger will be cancelled and will terminate and expire as of that closing of
the  merger.  SpaceDev  will  assume  no  options,  warrants  or other rights to
purchase  Starsys  common  stock  pursuant  to  the  merger.

     Loan  Repayments.  At  the closing of the merger, SpaceDev will (i) pay off
the  remaining  principal  and interest of all loans to Starsys from Vectra Bank
Colorado, which we refer to as Vectra, together with any other costs incurred in
connection  with those loans, (ii) cancel and terminate the secured loan of $1.2
million  and  all  accrued interest and fees, from SpaceDev to Starsys, which we
refer  to  as  the  SpaceDev  loan,  and (iii) pay off subordinated loans in the
aggregate  amount  of  approximately $920,000 owed by Starsys to certain Starsys
shareholders.  SpaceDev will not be obligated to pay off more than $4,600,000 in
the  aggregate  (excluding the amount of the SpaceDev loan) for all of the loans
and  related  costs described above. The SpaceDev's loan was described in a Form
8-K  filed  on  September  14,  2005.

     Reservation  of  Options.  SpaceDev  has  agreed to reserve for issuance to
Starsys officers, employees and consultants options to buy a number of shares of
SpaceDev  common stock equal to at least 15% of the number of shares of SpaceDev
common  stock  issued at the closing and as earnout consideration. SpaceDev will
seek  approval  of  its  shareholders to increase the amount of shares available
under  the  SpaceDev  2004 Equity Incentive Plan, or under a new stock or equity
plan  to  be  adopted,  to  provide  sufficient reserves for the issuance of the
options  referenced  above.

     Representations,  Warranties  and Covenants. SpaceDev and Starsys have made
customary  representations,  warranties  and  covenants in the merger agreement,
including,  among others, covenants (i) not to (A) solicit proposals relating to
alternative  business  combination  transactions  or  (B)  subject  to   certain
exceptions,  enter  into  discussions  concerning  or  provide   information  in
connection  with  alternative  business  combination transactions, (ii) to cause
shareholder meetings to be held to consider approval of the merger agreement (in
the  case of Starsys and SpaceDev), and (iii) subject to certain exceptions, for
the  board  of directors of Starsys to recommend adoption by its shareholders of
the  merger  agreement  and  for the board of directors of SpaceDev to recommend
adoption  by  its  shareholders  of  the  merger  agreement.

     Conditions  to  Closing.  Consummation  of the merger is subject to certain
closing  conditions,  including, among others, shareholder approvals, absence of
governmental restraints, effectiveness of a Form S-4 registration statement, and
accuracy  of  representations.  The merger agreement allows SpaceDev and Starsys
to  terminate  the  merger  agreement upon the occurrence (or non-occurrence) of
certain  events.

     Following  the  effective  time  of  the  merger,  Scott  Tibbitts,  who is
currently  the  Chief  Executive  Officer  of  Starsys,  is expected to become a
director  and  executive  officer  of  SpaceDev.

     A  copy  of  the  merger agreement is attached hereto as Exhibit 2.1 and is
incorporated  herein  by  reference.  The  foregoing  description  of the merger
agreement  is  qualified  in  its  entirety by reference to the full text of the
merger  agreement.  Robert Vacek is expected to remain the President of Starsys.
