Exhibit 2.2

                      AMENDMENT NO. 1 TO ASSET PURCHASE AGREEMENT


     THIS AMENDMENT NO. 1 TO ASSET PURCHASE AGREEMENT,  dated as of February 12,
1997 (this "Amendment"),  is by and among SPACEHAB ACQUISITION CORP., a Delaware
corporation,   as  buyer  ("Buyer"),   SPACEHAB,   INCORPORATED,   a  Washington
corporation ("SPACEHAB"),  ASTROTECH SPACE OPERATIONS,  L.P., a Delaware limited
partnership ("Seller"), and NORTHROP GRUMMAN CORPORATION, a Delaware corporation
("Parent").

     Reference is made to the Asset  Purchase  Agreement  dated February 5, 1997
(the  "Asset  Purchase  Agreement")  by and among  Buyer,  SPACEHAB,  Seller and
Parent.  Capitalized  terms  used  herein  without  definition  shall  have  the
respective  meanings  set forth in the  Asset  Purchase  Agreement.  Each of the
undersigned  hereby agrees to the following  with respect to the Asset  Purchase
Agreement:

     1.  Inasmuch as Seller is unable to deliver all  third-party  consents  and
approvals to transfer  all of the  Contracts to Buyer at the Closing as required
by Section 8.6 of the Asset  Purchase  Agreement,  Buyer hereby  agrees to waive
this closing  condition in light of the agreement by Seller to permit Buyer full
use of any premises demised  pursuant to any lease not yet effectively  assigned
with all  required  third party  consents  until the earlier of (i) the date the
lease is so assigned or (ii) the date the lease expires in  accordance  with its
term, and to continue as prime  contractor or customer on each Contract that has
not been  effectively  assigned  and/or  novated with all  required  consents of
third-parties,  including  but not  limited  to the  following  Contracts:  NASA
Kennedy Space Center  (Contract  No.  NAS10-12270);  USAF Fuel Supply  Agreement
(Vandenberg);  USAF Fuel Supply Agreement (FL);  McDonnell Douglas  Astronautics
Company;  Motorola, Inc.; and United Paradyne Corporation for a period ending on
the earlier of (i) the date on which all required consents for said Contract are
received  and the  assignment  thereof  becomes  fully  effective  or  (ii)  the
expiration  of said  Contract.  Seller  covenants  that it shall retain Buyer to
perform  all work  under said  Contracts  and to receive  all  benefits  of said
Contracts, including but not limited to all monies received under said Contracts
(without  any  deduction  for any reason,  including  but not limited to service
charges and overhead  assessments other than actual costs payable to contracting
parties,  including  without  limitation  rental  payments),  and to receive any
materials or supplies under Contracts where Seller is the vendee. Seller further
agrees that it shall  retain its legal  existence in its current form during the
period that it is acting as the contracting party with any third-party  pursuant
to this  provision.  In addition,  Seller  agrees that it will not terminate any
such Contract  without the advance written  permission of Buyer.  Both Buyer and
Seller  agree  that they shall use their best  efforts  to  accomplish  all such
transfers  and  attendant  consents  as soon as is  reasonably  possible  and to
provide the assistance  provided in Section 7.3 of the Asset Purchase Agreement.
Buyer further agrees that it will defend and indemnify Seller and Parent against
any  claim  that may  arise  from  any  third-party  as a result  of the work it
undertakes during this  sub-contracting  arrangement or any obligation as vendee
from the Closing until such Contracts are assigned with all required consents to
Buyer in accordance with the terms of Buyer's indemnification under Section 10.3
et seq. of the Asset Purchase Agreement,  except that the dollar limitations set
forth in Section 10.3 shall not apply to this specific  indemnity.  For purposes
of clarity,  this specific  indemnity  shall extend to the end of any applicable
statute of limitations period.

     2. In light of the fact that a survey of the  Titusville,  FL facility  has
not yet been supplied to the title insurance  company that is writing the policy
on this  property  and  given  that the  title  insurance  company  is noting an
exception  to their  policy based on whatever  additional  matters  might be set
forth on said survey when it is delivered other than exceptions on Schedule B of
the title  insurance  policy (other than survey  exceptions),  Seller and Parent
agree to  indemnify  Buyer for any  matters  that may appear on the survey  that
impact  negatively the value of the property or its use that would require Buyer
to expend  funds to remove the  exception  in  accordance  with the terms of the
Seller's and Parent's  indemnification  under  Section 10.2 et seq. of the Asset
Purchase Agreement, except that the dollar limitations set forth in Section 10.2
shall not apply to this specific indemnity.

     3. In all other respects, the Asset Purchase Agreement shall remain in full
force and effect.

     This Amendment:  (a) shall be construed and enforced in accordance with the
laws of the  State  of New York  without  giving  effect  to the  choice  of law
principles  thereof;  (b) shall inure to the benefit of and be binding  upon the
successors  and  assigns  of the  parties  hereto,  nothing  in this  Amendment,
expressed or implied,  being intended to confer upon any other person any rights
or remedies hereunder; and (c) may be executed in two or more counterparts, each
of which shall be deemed an original but all of which together shall  constitute
one and the same  instrument.  The Section and other headings  contained in this
Amendment  are for  reference  purposes only and shall not affect in any way the
meaning or interpretation of this Amendment.




     IN WITNESS  WHEREOF,  the parties  hereto have duly executed this Amendment
the day and year first above written.
