Item 1. Security and Issuer.

     This Schedule 13D relates to the Common Stock, no par value, of Spacehab,
Incorporated, a Washington corporation (the "Company"), which has its principal
executive offices at 300 D Street, SW, Suite 814, Washington, D.C. 20024.


Item 2. Identity and Background.

     This Schedule 13D is filed by DaimlerChrysler Aerospace AG (the "Reporting
Person"), a stock corporation formed under the laws of the Federal Republic of
Germany. The Reporting Person is wholly owned by DaimlerChrysler
Luft-und-Raumfahrt Holding AG, a stock corporation organized under the laws of
the Federal Republic of Germany ("DCLR"). DCLR, in turn, is majority owned
(i.e., 93.83%) by DaimlerChrysler AG, a stock corporation organized under the
laws of the Federal Republic of Germany ("DC").

     The Reporting Person is principally engaged in aerospace projects.

     Attached as Appendix I is information concerning (i) the executive officers
and directors of the Reporting Person and (ii) each person controlling the
Reporting Person, as is required to be disclosed in response to Item 2 and
General Instruction C to Schedule 13D.

     Neither the Reporting Person nor any of the persons referred to in Appendix
I has, during the last five years, been convicted in a criminal proceeding
(excluding traffic violations and similar misdemeanors) or been a party to a
civil proceeding of a judicial or administrative body of competent jurisdiction
and as a result of such proceeding was or is subject to a judgment, decree or
final order enjoining future violations of, or prohibiting or mandating
activities subject to, U.S. Federal or state securities laws or finding any
violation with respect to such laws.


Item 3. Source and Amount of Funds or Other Considerations.

     The Reporting Person entered into a Preferred Stock Purchase Agreement with
the Company, dated as of August 2,1999 (the "Stock Purchase Agreement") (Exhibit
A hereto).

     Pursuant to the Stock Purchase Agreement, on August 5, 1999, the Reporting
Person acquired 975,000 shares (the "Initial Shares") of Series B Senior
Convertible Preferred Stock, no par value ("Preferred Stock"), for a purchase
price of $8,775,000, or $9 per share. In addition, the Stock Purchase Agreement
provides for the Reporting Person, subject to certain conditions (including the
shareholder approval described below), to purchase an additional 358,334 shares
(the "Subsequent Shares") of Preferred Stock for a purchase price of $3,225,006
($9 per shares) within five (5) business days of the approval by the Company's
shareholder of an amendment to the Company's Articles of Incorporation
increasing the authorized shares of Preferred Stock. Such shareholder approval
is to be sought at the meeting of shareholders scheduled to be held in October
1999.

                                   Page 3 of 6

<PAGE>

Item 4. Purpose of Transaction.

     The Initial Shares were acquired by the Reporting Person to become the
Company's leading strategic investor and in connection with a decision by the
Company and the Reporting Person to pursue strategic cooperative activities with
the Company in areas of mutual technological interest.

     In connection with, and as a condition to the acquisition of the Initial
Shares, the Reporting Person and the Company entered into (i) a Registration
Rights Agreement, dated as of August 5, 1999 (Exhibit B hereto), and (ii) a
Strategic Collaboration Agreement, dated as of August 5, 1999 (Exhibit C
hereto).

     Pursuant to the Stock Purchase Agreement and the Designation of Rights,
Terms and Preferences of Series B Senior Convertible Preferred Stock of the
Company as filed with the Secretary of State of the State of Washington on
August 2, 1999 (the "Certificate of Designations") (Exhibit D hereto), for as
long as the Reporting Person owns thirty percent (30%) of the Preferred Shares
purchased pursuant to the Agreement (inclusive of the Subsequent Shares) and/or
Common Stock of the Company issued upon conversion of said Preferred Shares, the
Reporting Person shall be entitled to designate one of the Company's directors.
Said director is to be a member of the Executive Committee of the Company's
Board of Directors. Mr. Joseph Kind, President of the Reporting Person's Space
Infrastructure Division, has been so designated by the Reporting Person and
joined the Company's Board on August 5, 1999.

     Although the Reporting Person has not formulated any definitive plans with
respect to the shares of Common Stock of the Company owned by it, the Reporting
Person may from time to time acquire, or dispose of, Common Stock and/or other
securities of the Company if and when it deems it appropriate, subject to the
restrictions imposed by Section 16 of the Securities Exchange Act of 1934, as
amended (the "Act"). The Reporting Person may formulate other purposes, plans or
proposals relating to any of such securities of the Company to the extent deemed
advisable in light of market conditions, investment policies and other factors.

     Except as described in this Item 4 and elsewhere in this Schedule 13D,
neither the Reporting Person nor any of the persons named on Appendix I to this
Schedule 13D has any plans or proposals which relate to or would result in: (a)
the acquisition by any person of additional securities of the Company, or the
disposition of securities of the Company; (b) an extraordinary corporate
transaction, such as a merger, reorganization or liquidation, involving the
Company or any of its subsidiaries; its subsidiaries; (d) any change in the
present Board of Directors or management of the Company, including any plans or
proposals to change the number or term of directors or to fill any existing
vacancies on the Board; (e) any material change in the present capitalization or
dividend policy of the Company; (f) any other material change in the Company's
business or corporate structure; (g) changes in the Company's charter, By-Laws
or instruments corresponding thereto or other actions which may impede the
acquisition of control of the Company by any person; (h) causing a class of
securities of the Company to be delisted from a national securities exchange or
cease to be authorized to be quoted in an interdealer quotation system of a
registered national securities association; (i) causing a class of equity
securities of the Company to become eligible for termination of registration
pursuant to Section 12(g)(4) of the Act, as amended; or (j) any action similar
to those enumerated above.

Item 5. Interest in Securities of the Issuer.

     The Reporting Person directly owns (a) 104,165 shares of Common Stock of
the Company (acquired in 1995) and (b) 975,000 shares of Preferred Stock, which
allow the Reporting Person to convert said Initial Shares into Common Stock as
described below. In addition, the Reporting Person is to purchase an additional
358,334 shares of Preferred Stock, as described in Item 3.

     The Initial Shares (i.e., the 975,000 of Preferred Stock) currently are
convertible by the Reporting Person, without the payment of additional
consideration, into an equal number of shares of Common Stock. The conversion
mechanism, as set forth in the Certificate of Designation, provides for the
conversion ratio to be adjusted for stock splits, combinations, certain
dividends and distributions, reclassifications, merger or reorganization.

     If the Reporting Person exercised its conversion rights with respect to the
Initial Shares within sixty days of the date of the Stock Purchase Agreement,
the Reporting Person would directly control a total of 1,079,165 shares (or
8.9%) of the issued and outstanding Common Stock of the Company. Such percentage
is based on the 11,205,310 shares of Common Stock reported as outstanding on
April 30, 1999 in the Company's Form 10-Q for the quarter ended March 31, 1999.
After purchase of the Subsequent Shares, which purchase is subject to
shareholder approval of an amendment to the Company's Articles of Incorporation
scheduled for October 1999, and assuming no changes to the Company's
capitalization, the Reporting Person would control, directly or indirectly
(i.e., through conversion of the Preferred Shares), a total of 1,437,334 shares
(or 11.5%) of the issued and outstanding Common Stock of the Company.

     Other than the transactions described in this Schedule 13D, no transactions
in the shares of Common Stock of the Company have been effected in the past 60
days by the Reporting Person.


Item 6. Contracts, Arrangement,  Understandings
        or Relationships with Respect to Securities of Issuer.

     Other than the transaction described in this Schedule 13D, no arrangements
currently exist between the Reporting Person and the Company with respect to the
securities of the Company.


Item 7. Material to be Filed as Exhibits.

Exhibit 1 Preferred Stock Purchase Agreement, dated as of August 2, 1999,
          between the Reporting Person and the Company.

Exhibit 2 Registration Rights Agreement, dated as of August 5, 1999, between the
          Reporting Person and the Company.

Exhibit 3 Strategic Collaboration Agreement, dated as of August 5, 1999, between
          the Reporting Person and the Company.

Company  consisting of consolidated  balance sheets as at March 31, 1999 and the
related consolidated  statements of income,  shareholders' equity and cash flows
for the three and  nine-month  periods then ended and the related notes thereto;

and all other reports, schedules, forms, statements and other documents filed by
the Company with the  Commission  since June 30, 1998 (in each case,  as amended

Schedule 5.5 hereto,  other than  liabilities  arising in the ordinary course of

financial information,  subject to the assumptions made in their preparation and
the  qualifications  set forth  therein,  and nothing has come to the  Company's
attention to cause it to believe that the financial  information and assumptions
upon which it was predicated were unreasonable as of the respective  preparation
dates thereof.

     (f) Nothing has come to the attention of the Company or any Subsidiary that
would  cause it to believe  that any of the  Disclosure  Material  contained  or
contains a false or  misleading  statement of a material  fact or omits to state
any  material  fact  necessary  in  order to make  the  statements  made in such
material,  in light  of the  circumstances  under  which  they  were  made,  not
misleading, provided that the financial information items referred to in Section
5.5(a)(iii) have not been updated since their respective dates of preparation.

     5.6 Litigation.

     Except as set forth in Schedule 5.6, there is no action, suit, arbitration,
proceeding,  investigation  or claim pending or, to the knowledge of the Company
or its Subsidiaries,  threatened,  in law, equity or otherwise before any court,
administrative  agency,  Governmental  Authority or arbitrator  which either (i)
questions  the  validity  of  this  Purchase  Agreement  or  any  of  the  Other
Transaction  Documents  or any action  taken or to be taken  pursuant  hereto or
thereto,  (ii) could have a Material Adverse Effect,  or (iii) would be required

returns are complete and correct.  The Company and each  Subsidiary  has paid or
caused to be paid all taxes, fees, assessments and other governmental charges or
levies  (including  interest


                                       15
<PAGE>


and  penalties)  that  are due and  payable  (whether  or not  shown on any such
return),  except  those  which  are  being  contested  by it in  good  faith  by
appropriate  proceedings  and in respect of which  adequate  reserves  are being
maintained on its books in accordance with GAAP. The Company and each Subsidiary
has  withheld  and paid all  taxes  required  to have  been  withheld  and paid,
including  taxes in  connection  with  amounts  paid or  owing to any  employee,
creditor,  independent  contractor or other third party. Neither the Company nor
any Subsidiary has any material  liabilities for taxes other than those incurred
in the ordinary course of business and in respect of which adequate reserves are
being maintained by it in accordance with GAAP.

by any Person.

     5.13 Properties.

     (a) Except as set forth in Schedule  5.13, the Company does not own, and no
Subsidiary owns, any real property. The Company and each Subsidiary has good and
marketable  title to its assets and other  properties  (including  tangible  and
intangible  personal  property)  free and clear of all Liens  other  than  Liens
disclosed in the most recent financial  statements of the Company referred to in
Section  5.5(a) and other  Liens  which  could not result in a Material  Adverse
Effect.  Certain real  property used by the Company or its  Subsidiaries  in the
conduct of their  respective  businesses  is held under lease,  as identified in
Schedule 5.13 hereto.

     (b) The  Company  and each  Subsidiary  has the  right  to and  does  enjoy
peaceful and undisturbed possession under all leases pursuant to which it leases
property.  Neither  the Company  nor any  Subsidiary  is aware of any pending or
threatened  claim or action by any lessor of any such  property to terminate any
such lease. All such leases are valid and in full force and effect,  and none of
such leases is in default.

     (c) All of the buildings,  machinery,  equipment and other tangible  assets
necessary  for the conduct of the Company's  business are in good  condition and
repair,  ordinary wear and tear excepted,  and are usable in the ordinary course
of business.  There are no defects in such assets or other  conditions  relating
thereto which, in the aggregate,  materially  adversely  affect the operation or
value of such  assets.  The Company  owns,  or leases  under valid  leases,  all
buildings,  machinery,  equipment and other  tangible  assets  necessary for the
conduct of its business.

properties  and business and (ii) the directors  and  executive  officers of the
Company  and its  Subsidiaries,  against  such  losses  and  risks,  and in such
amounts, as are customary in the case of corporations of established  reputation
engaged  in the  same or  similar  businesses  of  similar  size  and  similarly
situated.  The Company and its Subsidiaries  have not been refused any insurance
coverage, and existing insurance coverage of directors and executive officers of
the Company and its Subsidiaries  sought or applied for, and the Company and its
Subsidiaries  have no reason to believe  that they will be unable to renew their
existing  insurance coverage upon terms at least as favorable as those presently
in effect.

and has not experienced and does not expect to experience any substantial  labor
problems.  Neither the Company nor any  Subsidiary  has any  knowledge as to any
intentions  of any key employee or any group of employees to leave the employ of
the Company or of any  Subsidiary.  No employee of the Company

     (c) Any action taken by a Purchaser  Director in his capacity as a director
of  the  Company  (such  as  approving  or  authorizing  transactions,  adopting
resolutions,  etc.) shall be  considered  to be an action taken by such director
solely in his capacity as a director and not in any other capacity and shall not
be construed  as,  considered to be or deemed to be an action taken by Purchaser
and such action shall not in any way bind, obligate,  estop, waive the rights of

stockholders,  in the proxy  statement to be distributed in connection with such
meeting,  that the  Articles be amended to  increase  the  authorized  shares of

"Amendment") reflecting such amendment to the Articles of Incorporation.

otherwise  complying  with the Exchange  Act),  under  Section  12(b) or Section
12(g),  whichever  is  applicable,  of the  Exchange  Act,  with  respect to the

documents and reports as the  Commission  may require or prescribe for companies
whose stock has been registered pursuant to such Section 12(b) or Section 12(g),
whichever is applicable.

     (b) The Company will make whatever  other filings with the  Commission,  or
otherwise  make  generally  available  to the public  such  financial  and other

employees,  agents and stockholders  (collectively,  the "Indemnitees") and hold
them harmless against any loss, liability,  deficiency,  damage, expense or cost
(including  reasonable  legal  expenses)  (collectively  "Losses"),   which  any
Indemnitee may suffer, sustain or become subject to, directly or indirectly as a

Agreement or the  Registration  Rights  Agreement  the  Purchaser may proceed to
protect  and  enforce  its  rights by an action at law,  suit in equity or other
appropriate proceeding, whether for the specific performance of any agreement or
covenant contained herein or therein or for an injunction against a violation of

granted hereby or thereby or by law or for any other remedy  (including  without
limitation damages).

     (c) No  course  of  dealing  and no delay on the part of any  party to this

Registration Rights Agreement  specifically  enforced by any court having equity
jurisdiction,  it being  acknowledged  and agreed that any breach or  threatened
breach of the provisions of this Purchase  Agreement or the Registration  Rights
Agreement will cause irreparable injury to Purchaser and that money damages will

     2.   The facility utilizes two 6000 gallon underground storage tanks to
          receive and store washwater used during the cleaning and fueling of
          satellites. The washwater is treated by air stripping to remove
          volatile organic compounds prior to discharge to the tanks. The tanks
          are periodically pumped out by a waste disposal contractor.

     2.   The facility contains ceiling tiles, floor tiles, roofing material,
          and wallboard/joint compound which typically were manufactured in the
          past, and continue to be manufactured using some asbestos fibers,
          which are bound into a solid matrix and thus are not considered to be
          friable. No asbestos survey has been done to determine whether, in
          fact, such materials contain asbestos.

     3.   The facility generates waste oil, which may contain small
          concentrations of hazardous substances, and uses various alcohols,
          degreasing and cleaning agents, all of which are temporarily stored
          onsite in 55 gallon drums.

     4.   In the normal course of operations at the Company's facilities,
          customers of the Company and, less frequently, the Company itself,
          bring onto the Company's property, store and use Hazardous Material,
          usually in small quantities, the highest volumes of which pertain to
          anhydrous hydrozine, momomethylhydraxine and nitrogen tetroxide.
          Customers who bring chemicals onto the Company's Property are required
          by the Company to remove any wastes or residuals when they leave.

     County, California

     1.   The facility contains one pad-mounted liquid dialectric
          fluid-containing transformer which might contain PCBs, and it contains
          fluorescent lighting fixtures, some of which may include ballasts
          (capacitors) that contain PCBs.

     2.   The facility is situated on property owned by the United States and
          administered by the United States Air Force. The land was previously
          used by the Air Force for other purposes, which would have involved
          the disposal or release of Hazardous Material. Air Force environmental
          site assessments indicate an absence of Hazardous Material on the
          property.

     3.   The facility contains ceiling tiles, floor tiles, roofing material,
          and wallboard/joint compound and various types of mastic, which
          typically were manufactured in the past, and continue to be
          manufactured using some asbestos fibers, which are bound into a solid
          matrix and thus are not considered to be friable. No asbestos survey
          has been done to determine whether, in fact, such materials contain
          asbestos.

     4.   In the normal course of operations at the Company's facilities,
          customers of the Company, and, less frequently, the Company itself,

          Customers who bring chemicals onto the Company's Property are required
          by the Company to remove any wastes or residuals when they leave. The
          facility contains an internal fully enclosed concrete trench catchment
          to which spills of hazardous substances that occur during satellite
          preparation would drain.

acknowledged, the parties hereby agree as follows:

     Section 1. Definitions.

     As used in this  Agreement,  the  following  terms shall have the following
meanings:

     "Commission"  means the  Securities  and Exchange  Commission and any other
successor agency of the federal  government  administering the Securities Act or
the Exchange Act.

     "Exchange  Act" means the Securities  Exchange Act of 1934, as amended,  or
any  similar  successor  federal  statute,   and  the  rules,   regulations  and
interpretations of the Commission thereunder, all as the same shall be in effect
at the time.

     "Holder" means any person owning or having the right to acquire Registrable
Securities  (as  defined  herein)  or any  assignee  or  transferee  thereof  in
accordance with the provisions of the Purchase Agreement.

     "Person"  or  "person"  means  an  individual,  corporation,   partnership,

     "Registration  Demand" shall mean a written notice (i) from one (1) or more
Holders  stating  that the Holder or Holders  of a majority  of the  Registrable
Securities  as of  such  date  desire  to sell  all or part of such  Registrable

the  effective  date of this  Agreement  and on or before the tenth  anniversary
thereof, the Holders holding a majority of the Registrable Securities as of such
date may make a Registration Demand requesting registration under the Securities
Act of all or part of their  Registrable  Securities.  The Company shall use its
best efforts to cause the  Registrable  Securities as to which  registration  is
requested  in the  Registration  Demand  to be  promptly  registered  under  the
Securities Act (and in any event, such registration shall be effected within one
hundred  and eighty  (180) days  following  receipt of a  Registration  Demand).
Within ten (10) days after receipt of any such Registration  Demand, the Company
shall give written notice of the proposed  registration  to all other Holders of
Registrable  Securities.  All Holders of Registrable  Securities  shall have the
option  to have  all or part of their  Registrable  Securities  included  in any

included in such registration and the Company shall be obligated to include such
Registrable Securities in any such registration.

withdraws a registration  statement prior to the effectiveness thereof, (ii) the
sale of securities  subject to a  registration  statement  filed pursuant to any
Registration  Demand is not consummated because of the failure of the Company to
comply with the terms of this Agreement,  (iii) upon the  consummation of a sale
of  securities  subject  to a  registration  statement  filed  pursuant  to  any
Registration Demand, less than eighty percent (80%) of the securities registered
for sale or requested to be registered  for sale  thereunder are sold, or (iv) a
revocation  notice has been delivered and expenses of the Company have been paid
as  provided in Section 2.3 hereof,  such  registration


                                       2
<PAGE>


statement shall not be counted as one of the registrations to which such Holders
are entitled under this Section 2(b).

     (c) Right of Holders to Revoke Registration Demand. After the delivery of a
Registration  Demand  under this  Section 2, at any time prior to the  effective
date of the registration  relating to such  Registration  Demand,  the Holder or
Holders  making such  Registration  Demand may revoke such  request by providing
written  notice of such  revocation to the Company.  Any such  revocation  shall
count as one (1) of the  registrations  to which such revoking Holder or Holders
are entitled under Section 2(b) hereof unless the revoking Holder or Holders pay
all of the Company's  out-of-pocket  expenses with respect to such  registration
and  qualification  incurred to the date of the revocation  notice.  In any such
event, the registration  statement initiated by the revoked  Registration Demand
need not be filed.

     (d) Right of Company to Delay or  Postpone  Registration.  The  Company may
delay or  postpone  the  registration  of  Registrable  Securities  following  a
Registration Demand for a period of not more than ninety (90) days after receipt
of  such  Registration  Demand  if the  Company  furnishes  to  each  Holder  of
Registrable Securities to be included in the applicable registration a copy of a
resolution  of the Board of Directors  certified by the Secretary of the Company
stating that (i) the Company is in possession of material non-public information
which,  in the good  faith  judgment  of the Board of  Directors,  it  considers
prudent not to disclose in a registration  statement,  or (ii) such registration
would, in the good faith judgment of the Board of Directors,  adversely affect a
material  pending  third  party  financing,  reorganization,   recapitalization,
merger,  consolidation or similar transaction, or (iii) such registration would,
in the good faith  judgment of the Board of Directors,  have a Material  Adverse
Effect on the  Company's  business  or  financial  condition  and, in each case,
stating  the basis of such good  faith  judgment;  provided,  however,  that the
Company during such delay or postponement may not file a registration  statement
for securities to be issued and sold for its own account or that of anyone other
than the Holders.

     (e)  Selection  of  Underwriters.  The managing  underwriter  and all other
underwriters  participating  in any  underwritten  public offering  covered by a
Registration Demand shall be selected by the Holders of a majority of the shares
of  Registrable  Stock that  participate  in such  registration,  subject to the
approval  of  the  Board  of  Directors  of  the  Company,  which  shall  not be
unreasonably withheld.

     Section 3. Piggyback Registrations.

     (a)  Piggyback  Registration.  If at any  time or from  time to  time,  the
Company  shall  propose to register  any Common Stock (or any  warrants,  units,
convertibles,  rights or other securities related or linked to any shares of the
Common Stock) for public sale under the Securities  Act,  whether  pursuant to a
demand  by other  security  holders,  a shelf  registration  on  behalf of other
security holders (other than the existing effective shelf registration statement
for the Company's  outstanding  8% Convertible  Subordinated  Notes due 2007) or
otherwise,  then the Company shall give prompt  written notice to all Holders of
the proposed registration (but in no event shall such


                                       3
<PAGE>


notice be given later than forty-five (45) days before any such  registration is
filed with the  Commission).  If any Holders so request  within thirty (30) days
after receipt of such notice, the Company,  subject to the provisions of Section
3(c) shall include in such registration the Registrable Securities held or to be
held by such Holders and requested to be included in such registration.

     (b) Right of Company to Withdraw Registration.  The Company may at any time
prior to the  effectiveness  of any  such  registration  statement,  in its sole
discretion  and  following  notice  to any  Holder  that has,  or may,  elect to
participate in such registration, abandon the proposed offering. In the event of
any such abandonment, the Company shall bear all reasonable expenses incurred by
such Holder in connection with such withdrawn registration statement.

     (c) Underwriter's Clawback.  Notwithstanding anything contained in Sections
3(a) and 3(b)  hereof,  the  Company  shall not be  obligated  to  include  such
Registrable  Securities in such offering if the Company is advised in writing by
the managing  underwriter or  underwriters of such offering (with a copy to each
Holder)  that  such  offering  would  in its or their  good  faith  judgment  be
materially adversely affected by such inclusion,  in which case Holders shall be
entitled to participate in any such reduced number of Registrable Securities (if
any) which may be included in such  registration in proportion to their relative
holdings of Registrable  Securities.  Notwithstanding  the  foregoing,  any such
clawback shall be imposed pro rata on the Holders  exercising  piggyback  rights
and other security holders.

     Section 4. Expenses. Subject to the limitations contained in this Section 4
and except as  otherwise  specifically  provided in this  Agreement,  the entire
costs and  expenses of the  registrations  and  qualifications  pursuant to this
Agreement shall be borne by the Company.  Such costs and expenses shall include,
without limitation,  (i) the fees and expenses of counsel for the Company and of
its accountants, (ii) all other costs, fees and expenses of the Company incident
to  the  preparation,  printing  and  filing  under  the  Securities  Act of the
registration  statement and all amendments and  supplements  thereto,  (iii) the
cost of furnishing copies of each preliminary prospectus,  each final prospectus
and each  amendment or  supplement  thereto to  underwriters,  dealers and other
purchasers of the Registrable Securities, (iv) the costs and expenses (including
fees and disbursements of counsel) incurred in connection with the qualification
of the Registrable  Securities  under the securities or Blue Sky laws of various
jurisdictions,  and  (v)  the  reasonable  fees  and  expenses  of  one  counsel
representing  the  Holders  in  connection  with  each   registration  of  their
Registrable Securities. Such expenses shall not include any selling costs of the
Holders such as  underwriters'  discounts and selling  commissions  or any taxes
related to any sale of Registrable Securities by the Holders.

     Section 5. Obligations of the Company. Without limiting any other provision
hereof, in connection with any registration of Registrable  Securities  pursuant
to Section 2 or 3 hereof,  the Company shall (i) use its best efforts to prepare
and file with the  Commission as soon as reasonably  practicable a  registration
statement with respect to the shares required to be so registered;  (ii) use its
best  efforts to register  and qualify the shares  covered by such  registration
statement  under the  securities or Blue Sky Laws of such  jurisdictions  as any
Holder may reasonably  request;  (iii) take such other actions as are reasonable
and  necessary  to comply  with the  requirements  of the  Securities


                                       4
<PAGE>


Act, the Exchange  Act, and all  applicable  rules and  regulations  promulgated
thereunder; (iv) obtain the withdrawal of any order suspending the effectiveness
of the registration  statement at the earliest  possible time; and (v) provide a
transfer agent and registrar for the  Registrable  Securities not later than the
effective date of any registration statement.

     Section 6. Procedures.

     (a) In the case of each  registration  or  qualification  pursuant  to this
Agreement,  the  Company  will keep all  Holders  advised  in  writing as to the
initiation of proceedings for such  registration and qualification and as to the
completion  thereof,  and will  advise any such  Holder,  upon  request,  of the
progress of such proceedings.

     (b) The Company will use its best efforts,  at the Company's  sole expense,
to keep each registration and qualification  under this Agreement effective (and
in  compliance  with the  Securities  Act) by such action as may be necessary or
appropriate  for a period of one hundred  twenty (120) days after the  effective
date of such registration statement,  including,  without limitation, the filing
of  post-effective  amendments and supplements to any registration  statement or
prospectus necessary to keep the registration  statement current and the further
qualification  under any applicable  Blue Sky or other state  securities laws to
permit such sale or distribution, all as requested by the Holder or Holders.

     (c) The  Company  shall  immediately  notify  each  Holder on whose  behalf
Registrable  Securities have been registered pursuant to this Agreement,  at any
time when a prospectus  relating  thereto is required to be delivered  under the
Securities  Act,  of the  happening  of any  event  as a  result  of  which  the
prospectus  included in such registration  statement  (including any preliminary
prospectus),  as then in effect, includes an untrue statement of a material fact
or omits to state any material fact  required to be stated  therein or necessary
to make the statements therein not misleading in light of the circumstances then
existing.

     (d)  In the  case  of an  underwritten  offering  (and  in  the  case  of a
non-underwritten  offering  where the  Company  furnishes  the same to any other
selling securityholder), the Company will furnish to the underwriter(s) and each
Holder on whose behalf Registrable  Securities have been registered  pursuant to
this Agreement a signed counterpart,  addressed to the underwriter(s) (or in the
case of such  non-underwritten  offering,  each  Holder),  of (i) an  opinion of
counsel  for  the  Company,  dated  the  effective  date  of  such  registration
statement,  and (ii) a so-called "cold comfort" letter signed by the independent
public accountants  certifying the Company's  financial  statements  included in
such registration statement, and such opinion of counsel and accountants' letter
shall cover  substantially  the same matters  with respect to such  registration
statement  (and  the  prospectus  included  therein)  and,  in the  case of such
accountants'  letter,  with  respect  to events  subsequent  to the date of such
financial statements, as are customarily covered in opinions of issuer's counsel
and in  accountants'  letters  delivered  to  underwriters  in  connection  with
underwritten public offerings of securities.


                                       5

     (e) Without  limiting any other  provision  hereof,  in connection with any
registration of Registrable  Securities  under this Agreement,  the Company will
comply with the  Securities  Act, the Exchange  Act,  all  applicable  rules and
regulations  of the  Commission,  and all  other  applicable  laws and will make
generally   available  to  its  securities   holders,   as  soon  as  reasonably
practicable,  an earnings  statement  covering a period of at least  twelve (12)
months,  beginning  with the first month of the first fiscal  quarter  after the
effective date of such registration  statement,  which earnings  statement shall
satisfy the provisions of Section 11 (a) of the Securities Act.

     (f) In connection  with any  registration of Registrable  Securities  under
this  Agreement,  the  Company  will,  if  requested  by  underwriters  for  any
Registrable Securities included in such registration, enter into an underwriting
agreement with such  underwriters  for such offering,  such agreement to contain
such  representations  and  warranties  by the  Company and such other terms and
provisions as are customarily contained in underwriting  agreements with respect
to secondary distributions,  including, without limitation,  provisions relating
to indemnification. The Holders on whose behalf Registrable Securities are to be
distributed  by such  underwriters  shall be  parties  to any such  underwriting
agreement,  and the  representations and warranties by, and the other agreements
on the part of, the  Company to and for the benefit of such  underwriters  shall
also be made to and for the benefit of such Holders. Such underwriting agreement
shall also comply with Section 8 hereof.

     (g) If the Company at any time  proposes to register any of its  securities
under the Securities  Act, other than pursuant to a request made under Section 2
hereof,  whether or not for sale for its own account, and such securities are to
be distributed by or through one or more underwriters, then the Company will use
its  best  efforts,  if  requested  by any  Holder  requesting  registration  of
Registrable  Securities in connection therewith pursuant to Section 3 hereof, to
arrange for such  underwriters to include such Registrable  Securities among the
securities to be distributed by or through such underwriters.

     (h) In  connection  with the  preparation  and filing of each  registration
statement registering Registrable Securities,  the Company will give any Holders
on  whose  behalf  such  Registrable  Securities  are to be so  registered,  any
underwriters participating in any such disposition of Registrable Securities and
their respective counsel and accountants,  the opportunity to participate in the
preparation of such registration statement,  each prospectus included therein or
filed with the Commission, and each amendment thereof or supplement thereto, and
will  give  each  of  them  such  access  to its  books  and  records  and  such
opportunities  to discuss the  business of the Company  with its  officers,  its
counsel and the independent  public accountants who have certified its financial
statements,  as shall be  necessary,  in the  opinion  of such  Holders  or such
underwriters or their respective  counsel,  in order to conduct a reasonable and
diligent  investigation  within  the  meaning  of the  Securities  Act.  Without
limiting the foregoing,  each  registration  statement,  prospectus,  amendment,
supplement or any other document filed with respect to a registration under this
Agreement  shall be subject to review and  reasonable  approval  by the  Holders
registering Registrable Securities in such registration and by their counsel.


                                       6

     Section 7. Furnishing of Documents.  The Company will, at its sole expense,
furnish to each holder with  respect to which  registration  has been  effected,
such number of registration  statements,  prospectuses,  offering  circulars and
other documents  incident to any  registration or  qualification  referred to in
this  Agreement  as any such  Holder from time to time may  reasonably  request.

     Section 8. Indemnification of Holders.

     (a) Subject to the  conditions  set forth  below,  in  connection  with any
registration of Registrable  Securities  pursuant hereto,  the Company agrees to
indemnify and hold harmless each Holder and any  underwriters,  selling brokers,
dealer managers and similar securities industry professionals participating in a
distribution  covered by a registration  statement,  their respective  officers,
directors and affiliates (collectively, the "Indemnitees"):

          (i) against any and all losses, claims, damages or liabilities,  joint
     or  several,   and  expenses  whatsoever  arising  out  of  or  based  upon
     (including,  but not limited to, any and all expense whatsoever  reasonably
     incurred by any of the Indemnities in investigating, preparing or defending
     any litigation, commenced or threatened, or any claim whatsoever based upon
     or arising out of) (A) any untrue or alleged untrue statement of a material
     fact  contained  in  any  preliminary  prospectus,   or  any  amendment  or
     supplement thereto,  the registration  statement or the prospectus (each as
     from time to time amended and supplemented), or in any application or other
     document  executed  by  the  Company  or  based  upon  written  information
     furnished by the Company filed in any  jurisdiction in order to qualify the
     Common Stock under the securities laws thereof or otherwise incident to the
     registration or the  qualification of the Common Stock under the Securities
     Act or any state  securities  laws  applicable  to the Company;  or (B) the
     omission or alleged  omission  from any item  referred to in the  preceding
     clause of a material  fact  required to be stated  therein or  necessary to
     make the statements  therein not misleading;  or (C) any other violation or
     alleged  violation of  applicable  federal or state law, rule or regulation
     relating to action or inaction by the Company in  connection  with any such
     registration or qualification;  provided,  however, that with respect to an
     Indemnitee, the indemnity agreement contained herein shall not apply to any
     loss,  claim,  damage,  liability or action of or involving such Indemnitee
     arising  out of or based  upon any untrue or alleged  untrue  statement  or
     omission  made in  reliance  upon and in  conformity  with any  information
     furnished in writing to the Company by such  Indemnitee  expressly  for use
     therein; and

          (ii) subject to the proviso contained in subsection (i) above, against
     any and all losses, claims, damages and liabilities,  joint or several, and
     expenses  whatsoever  to  the  extent  of  the  aggregate  amount  paid  in
     settlement  of any  litigation,  commenced or  threatened,  or of any claim
     whatsoever  based upon any such  untrue  statement  or omission or any such
     alleged untrue  statement or omission  (including,  but not limited to, any
     and all expenses whatsoever reasonably incurred by the Indemnitees or their
     respective  counsel in  investigating,  preparing or defending  against any
     such  litigation or claim) if such  settlement


                                       7
<PAGE>


is effected  with the written  consent of the Company which consent shall not be
unreasonably withheld.

     (b) The  Company  will  enter  into an  underwriting  agreement  and  other
agreements  with the  underwriter or  underwriters  for any offering  registered
under the Securities Act pursuant to this Agreement and with the Holders selling
Registrable   Securities  pursuant  to  such  offering,  and  such  underwriting
agreement and other agreements shall contain  customary  provisions with respect
to indemnification  which shall, at a minimum,  provide the  indemnification set
forth above.

     (c) The procedure for  indemnification  by the Company under this Section 8
shall be as follows:

          (i)  if  any  action  or  proceeding   (including   any   governmental
     investigation   or  inquiry)  shall  be  brought  or  asserted  against  an
     Indemnitee  in respect of which  indemnity  may be sought from the Company,
     such  Indemnitee  shall  promptly  notify the Company in  writing,  and the
     Company  shall be  entitled to assume the defense  thereof,  including  the
     employment of counsel  reasonably  satisfactory  to such Indemnitee and the
     payment of all reasonable expenses related thereto (including those of such
     counsel),  by  delivering  written  notice of its  election to do so within
     fifteen  (15)  days  following  receipt  of notice  from  such  Indemnitee;
     provided  that the failure of the  Indemnitee  to give the  Company  prompt
     notice  as   provided   herein   shall  not  relieve  the  Company  of  its
     indemnification  obligations  hereunder  except to the extent,  if any, the
     Company shall have been prejudiced thereby;

          (ii) such Indemnitee  shall have the right to employ separate  counsel
     in any such action and to participate in the defense thereof,  but the fees
     and  expenses  of  such  separate  counsel  shall  be the  expense  of such
     Indemnitee unless (A) the Company has agreed to pay such fees and expenses,
     or (B) the  Company  has  failed to assume the  defense  of such  action or
     proceeding by delivering  the notice  referred to in subsection (i) hereof,
     or (C) the Company has failed to employ counsel reasonably  satisfactory to
     the Indemnitee within ten (10) days after the Company has elected to assume
     the defense of such action  pursuant to subsection  (i) hereof,  or if such
     counsel  has  been  employed  by  the  Company,  at  any  time  after  such
     employment,  such  counsel  ceases  (in  the  reasonable  judgment  of  the
     Indemnitee) to be reasonably satisfactory,  or (D) the named parties to any
     such action or proceeding  (including any impleaded  parties)  include both
     such  Indemnitee  and the  Company,  and such  Indemnitee  shall  have been
     advised by counsel that there may be one or more legal  defenses  available
     to such Indemnitee that are different from or additional to those available
     to the Company  creating a conflict of interest on the part of such counsel
     to represent both parties; and

          (iii) if such  Indemnitee  notifies  the  Company in  writing  that it
     elects  to  employ  separate  counsel  at the  expense  of the  Company  as
     permitted by the provisions of the preceding  subsection  (ii), the Company
     shall not have the right to assume the defense of such action or proceeding
     on behalf of such Indemnitee.  The foregoing  notwithstanding,  the


                                       8
<PAGE>


     Company  shall not be liable for the  reasonable  fees and expenses of more
     than one (1) separate firm of attorneys at any time for such Indemnitee and
     any other  Indemnitee  (which firm shall be  designated  in writing by such
     Indemnitee)  in  connection  with  any one such  action  or  proceeding  or
     separate but substantially similar or related actions or proceedings in the
     same  jurisdiction   arising  out  of  the  same  general   allegations  or
     circumstances.

     Section 9. Indemnification of the Company.

     Each  Holder,  in  any  registered  offering  pursuant  hereto,  agrees  to
indemnify and hold  harmless the Company,  its officers and directors and agents
and each other  person,  if any, who controls the Company  within the meaning of
Section  15 of the  Securities  Act  against  any and all  losses,  liabilities,
claims,  damages  and  expenses of the kind  indemnified  against by the Company
under Section 8 above based upon  statements or omissions or alleged  statements
or  omissions,  if any, made in any  preliminary  prospectus,  the  registration
statement  or  prospectus  or  any  amendment  or  supplement   thereof  or  any
application or other document in reliance upon, and in conformity with,  written
information  furnished  by such Holder to the Company  expressly  for use in any
preliminary  prospectus,   the  registration  statement  or  prospectus  or  any
amendment or supplement thereof or in any such application or other document. In
no event,  however,  shall the liability hereunder of any Holder be greater than
the dollar  amount of the  proceeds  received  by such  Holder  upon sale of its
Registrable  Securities  in the  offering  giving  rise to such  indemnification
obligation.  In case any action  shall be brought  against the  Company,  or any
other person so indemnified, in respect of which indemnity may be sought against
any Holder,  such Holder  shall have the rights and duties given to the Company,
and each person so  indemnified  shall have the rights and duties  given to such
Holder,   by  the   provisions   of  Section  8  above  and  the  procedure  for
indemnification shall be as provided for in Section 8.

     Section 10. Reports Under Exchange Act. With a view to making  available to
each Holder the benefits of Rule 144  promulgated  under the  Securities Act and
any other rule or regulation of the  Commission  that may at any time permit the
Holder to sell  securities of the Company to the public without  registration or
pursuant to a registration with the information required to be disclosed on Form
S-3, the Company agrees to use its best efforts to satisfy the  requirements  of
all  such  rules  and  regulations   (including  the   requirements  for  public
information,  registration  under  the  Exchange  Act and  timely  reporting  to
the-Commission).  The Company shall (whether or not it shall then be required to
do so) timely file such information, documents and reports as the Commission may
require or prescribe under Section 13 or 15(d)  (whichever is applicable) of the
Exchange  Act,  for  so  long  as  the  Company  is  subject  to  the  reporting
requirements  of either  Section 13 or 15(d) of the  Exchange  Act.  The Company
shall  forthwith  upon  request  furnish  any Holder of  applicable  Registrable
Securities (i) a written statement by the Company that it has complied with such
reporting  requirements,  (ii) a copy of the most  recent  annual  or  quarterly
report of the Company and (iii) such other  reports and  documents  filed by the
Company with the Commission as such Holder may reasonably request.


                                       9
<PAGE>


     Section 11.  Obligations of Holders.  It shall be a condition  precedent to
the obligation of the Company to register any  Registrable  Securities  pursuant
hereto  that each  Holder  shall (i)  furnish to the  Company  such  information
regarding the  Registrable  Securities  and the intended  method of  disposition
thereof  and other  information  concerning  such  Holder as the  Company  shall
reasonably  request and as shall be required in connection with the registration
statement to be filed by the Company, and (ii) agree to abide by such additional
customary terms affecting the proposed  offering as may be reasonably  requested
by the managing underwriter of such offering.

     Section  12.  Certain  Limitations  in  Connection  with  Future  Grants of
Registration Rights.

     (a) From and after the date of this Agreement,  the Company shall not enter
into any agreement  with any holder or  prospective  holder of any of its Common
Stock  providing for the granting to such holder of demand  registration  rights
unless such  agreement  includes  provisions  to the effect that (i) the Company
will give each Holder  notice at least thirty (30) days prior to the filing of a
registration  statement  pursuant to the exercise of such rights and (ii) if any
Holder  requests  inclusion  of  Registrable  Securities  in  such  registration
statement  within  thirty  (30) days  after  receipt of such  notice,  then such
Holder's  Registrable  Securities  requested to be so included will be on a pari
passu basis in proportion to the securities each selling securityholder requests
to be  registered  if marketing  factors  require a limitation  on the number of
securities to be included in such registration statement.

     (b) From and after the date of this Agreement,  the Company shall not enter
into any agreement  with any holder or  prospective  holder of any of its Common
Stock  providing for the granting to such holder of  incidental  or  "piggyback'
registration  rights  unless such  agreement  includes  provisions to the effect
that,  in the case of a registered  underwritten  public  offering of the Common
Stock to which Section 3 hereof  applies,  such agreement  gives priority to the
Holders of  Registrable  Securities  requested  to be so included  if  marketing
factors  require a  limitation  on the  number  of shares of Common  Stock to be
included in such offering.

     Section 13.  Suspension of Sales.  Upon receipt of written  notice from the
Company that a  registration  statement,  preliminary  prospectus  or prospectus
contains  an untrue  statement  of a  material  fact or an  omission  to state a
material fact required to be stated in a registration statement or prospectus or
necessary to make the  statements  in a  registration  statement,  prospectus or
preliminary  prospectus not misleading,  each Holder shall forthwith discontinue
disposition of Registrable  Securities  until such Holder has received copies of
the  supplemented  or amended  prospectus,  or until  such  Holder is advised in
writing by the registrant that the use of the prospectus may be resumed, and, if
so directed by the  registrant,  such Holder shall deliver to the registrant (at
the registrant's  expense) all copies,  other than permanent file copies then in
such Holder's possession, of the prospectus covering such Registrable Securities
current at the time of receipt of such notice.

     Section 14. Holdback. Except for transfers made in transactions exempt from
the registration  requirements under the Securities Act pursuant to Section 4(2)
thereof or  pursuant  to


                                       10
<PAGE>


Rule  144A,  upon  the  written  request  of  the  managing  underwriter  of any
underwritten  offering of the Common  Stock,  neither the Company nor any Holder
shall sell, make any short sale of, loan,  grant any option for the purchase of,
or  otherwise  dispose of any Common  Stock  (other than those  included in such
registration) without the prior written consent of such managing underwriter for
a period (not to exceed  thirty (30) days before the  effective  date and ninety
(90) days thereafter) that such managing  underwriter  reasonably  determines is
necessary in order to effect the underwritten public offering. In addition,  the
Company will cause each of the officers and directors of the  registrant and any
future  grantee  of  registration  rights to enter  into  substantially  similar
hold-back  agreements with such managing  underwriter covering at least the same
period.

     Section 15. Changes in Registrable  Securities or Preferred Stocks. If, and
as often as, there are any changes in the  Registrable  Securities  or Preferred
Stock by way of stock split, stock dividend, combination or reclassification, or
through merger,  consolidation,  reorganization or  recapitalization,  or by any
other means,  appropriate  adjustment  shall be made in the  provisions  of this
Agreement,  as may be required, so that the rights and privileges granted hereby
shall continue with respect to the Registrable Securities as so changed.

     Section 16.  Specific  Performance.  The Company agrees and stipulates that
the remedies at law of the Holders in the event of any default by the Company in
the performance of or compliance with any of the terms of this Agreement are not
and will not be adequate and that, to the fullest extent  permitted by law, such
terms may be specifically  enforced by a decree for the specific  performance of
any agreement contained herein or by an injunction against a violation of any of
the terms hereof or otherwise. Such remedies and all other remedies provided for
in this Agreement shall,  however,  be cumulative and not exclusive and shall be
in addition to any other remedies which a party may have under this Agreement or
otherwise.

     Section 17. Notices.  All notices,  demands and other  communications to be
given or delivered  under or by reason of the  provisions of this Agreement will
be in writing and will be deemed to have been given when personally delivered or

                        STRATEGIC COLLABORATION AGREEMENT

THIS  AGREEMENT  is entered  into this 5th day of August  1999,  by and  between
DaimlerChrysler Aerospace AG ("DASA"), a German corporation,  acting through its
Space Infrastructure  Division,  with offices located at Hunefeldstrasse 1-5, PO
Box  105909,  D-28059  Bremen,  Germany  ("DASA-RI");   and  Spacehab,  Inc.,  a
Washington  State  corporation  with offices located at Suite 814, 300 D Street,
S.W.,  Washington,  D.C.  20024,  U.S.A.  ("Spacehab")  (DASA and  Spacehab  are
hereafter collectively referred to as the "parties").

                              W I T N E S S E T H:
                              --------------------

     WHEREAS, Spacehab develops, owns and operates pressurized and unpressurized
modules and other equipment for use in  transportation,  research and logistical
support on board the United States National Aeronautics and Space Administration
("NASA") Space Shuttle; and

     WHEREAS, DASA has been a shareholder in Spacehab since 1995; and

     WHEREAS, pursuant to a Collaboration Agreement effective July 24, 1995 (the
"1995  Collaboration  Agreement"),  the  parties  have  cooperated  in the joint
pursuit of  technological  innovations  and new  business  opportunities  in the
environment of space; and

     WHEREAS,  DASA has, as of August 2, 1999,  entered  into a Preferred  Stock
Purchase  Agreement  with  Spacehab  to  increase  its equity  participation  in
Spacehab to  approximately  Eleven and  One-Half  Percent  (11.50%)  through the
acquisition of shares in a new class of preferred  stock (the "Spacehab  Stock")
with  the  view  to  becoming   Spacehab's   leading  strategic   investor  (the
"Subscription Agreement"); and

     WHEREAS,  the  parties  have agreed to update and expand the scope of their
Collaboration  Agreement to reflect their current objectives in cooperating with
one another on technical and financial grounds;

     WHEREAS,  the parties envisage also cooperating beyond the scope defined in
this  Collaboration  Agreement and will be free to propose  additional  business
opportunities for one another's consideration;

     NOW, THEREFORE,  in consideration for the mutual covenants and undertakings
herein contained, the parties have agreed as follows:


<PAGE>


     1. Exclusive Common Business Segments.

     1.1 The parties agree,  during the term hereof, to collaborate  technically
and  financially in the following  areas of mutual  technological  interest (the
"Exclusive Common Business Segments"):

          (a)  Human  space  flight   support  and  research   services  in  the
     unpressurized domain, including the development and procurement of required
     flight and ground hardware, software and related payloads; and

          (b)  Acquisition,  preparation  and  performance  of  sounding  rocket
     missions  excluding,  however,  DASA-RI's ongoing TEXUS and MAXUS programs,
     and

          (c)Inflatable  structures  excluding,  however, the Inflatable Reentry
     and Descent Technology and its applications.

Schedule 1.1  attached  hereto and hereby  incorporated  into and made a part of
this Agreement sets forth the parties' agreed areas of collaboration  within the
Exclusive Common Business Segments as of the execution of this Agreement.  It is
understood  that,  except as set forth in sections 1.5, 1.6 and 2.4.2 below, the
parties'  engagement in new lines of business and activities  falling within the
Exclusive  Common Business  Segments beyond those addressed in Schedule 1.1 will
hereafter  be decided by the parties'  Joint  Management  Committee  pursuant to
article  2 of this  Agreement.  The  parties  intend to  invest  jointly  in the
procurement of flight  hardware and software as a  prerequisite  for offering to
NASA and other  customers a  commercial  service  based on these assets and will
also pursue  other  upcoming  business  opportunities  in the  Exclusive  Common
Business Segments.

     1.2  Within  the  framework  of this  cooperation,  DASA will  receive  and
Spacehab will place with DASA-RI contracts  (preferably  development  contracts)
with a value of at least $12  million  (U.S.) by  December  31,  2000  ("DASA-RI
Minimum Contract Award").

     1.3 Based on their joint market  assessment the parties agree that,  during
calendar  year 2001 at least $13 million  (U.S.) and in  calendar  year 2002 and
beyond an average of $26 million in annual  revenues  (but in no event less than
an aggregate  of $65 million by the end of 2003) will be  generated  for DASA-RI
through the parties'  collaboration  on the  projects  listed in Schedule 1.1 in
sales to NASA and other  customers.  These  revenues will be generated  from (1)
customer  contracts for integration and operation services and (2) contracts for
the leasing of hardware procured through the parties' joint investments,  if any
("DASA-RI


                                      -2-
<PAGE>


Minimum Revenue").  These amounts are understood to be in addition to and not to
include the value of the Minimum  Contract  Award  defined in section 1.2 above.
The average  annual and aggregate  revenues  generated  referred to in the first
sentence of this Section 1.3 are subject to unforeseen events beyond the control
of Spacehab  which  prevent  Spacehab  from  generating  such  revenues  despite
Spacehab's  reasonable best efforts to do so. Spacehab will take reasonable best
efforts to minimize the effects of any unforeseen events.

     1.4 Spacehab  agrees that,  except as permitted  under section 2.4.2 below,
during the term of this  Agreement,  it will not enter into  agreements with any
third parties for engagement in work or cooperation falling within the Exclusive
Common Business Segments.

     1.5 The parties  hereby agree that any program  already in  development  by
either party shall be exempted from the terms of this Agreement.

     1.6  DASA-RI  shall be free to pursue new  business  opportunities  falling
within the Exclusive Common Business Segments (except for projects in the United
States in competition with business opportunities pursued by Spacehab),  whether
in Europe or elsewhere, without the participation of Spacehab.

     1.7 The parties may agree to collaborate  jointly with third parties in any
activities  which they jointly  undertake  within the Exclusive  Common Business
Segments.

     2. Joint Management Committee.

     2.1 The parties'  collaboration in the Exclusive  Common Business  Segments
shall be conducted  under the  direction  and  oversight  of a Joint  Management
Committee (the "Committee").

     2.2 The Committee shall be comprised of an equal number of  representatives
designated  by Spacehab  and  DASA-RI.  They shall choose their own chairman and
adopt procedural rules of governance.

     2.3 The  Committee  shall meet at least four times a year and shall operate
by  consensus.  Meetings may be held by telephone or other  electronic  means by
which all members present may hear and be heard by one another.

     2.4  The  Committee  shall  be  responsible  for  overseeing  the  parties'
implementation  of the schedule of agreed lines of business and  activities  set
forth in Schedule 1.1 hereto. To this end the Committee will periodically review
all active joint projects.  Spacehab will and DASA-RI, at its sole election, may


                                      -3-
<PAGE>


present to the Committee  during the term hereof  additional  or new  commercial
opportunities  not reflected or addressed in Schedule 1.1 but falling within the
Exclusive Common Business Segments. Such presentation will include a preliminary
business plan indicating the key business  parameters of the  opportunity.  Upon
receipt of such a plan the  Committee  will do one of the  following at its next
meeting

          (a)  Agree that the candidate project shall be considered further, or

          (b)  Agree that the candidate project should not be pursued as a joint
               project,  in which  case  the  proposing  party  shall be free to
               pursue the opportunity independently, or

          (c)  Fail to agree on either (a) or (b), in which case  section  2.4.2
               below shall apply.

     2.4.1 In the case a decision is taken under  paragraph (a) above, a project
manager from each party shall be assigned to draft a business plan and a project
plan to include  proposed  investments  by the  parties,  if any, as well as the
development and operations structures for implementation of the opportunity. The
Committee  shall  review the  completed  business  and  project  plan and either
approve the project for  implementation or decide that the project should not be
pursued as a joint project.  The Committee may approve complete  implementation,
or  require  the  project  manager to return for  incremental  authorization  at
specific milestones in the project plan.

     2.4.2  If  the  parties  elect  by  consensus  not  to  collaborate  on any
commercial  opportunity  within the  Exclusive  Common  Business  Segments,  the
proposing   party   shall  be  free  to  pursue  such   commercial   opportunity
independently from the other party, including,  should it so elect, jointly with
one or more  third  parties.  If the  parties,  following  repeated  good  faith
efforts, fail to reach consensus on how to respond to any commercial opportunity
within the Exclusive Common Business  Segments  presented to the Committee,  the
Committee  shall refer the issue for  resolution by the Chairman of Spacehab and
the  President  of  DASA-RI,  who shall meet and  confer on the  subject in good
faith.  If,  following  such effort to resolve a bona fide deadlock  between the
parties,  the parties are still  unable to reach  consensus on how to respond to
the commercial  opportunity within the Exclusive Common Business Segments,  then
either party shall be free to engage in the business opportunity in question.


                                      -4-
<PAGE>


     2.4.3  If the  parties  fail to reach  consensus  following  the  procedure
defined in section  2.4.2  above,  and one party  elects to pursue the  business
opportunity on its own (the "Electing Party"),  then the other party will have a
right of first  refusal  to match  bona  fide  proposals  by third  parties  for
subcontract work in pursuit of such opportunity for the Electing Party. Spacehab
expressly agrees in such instance,  however, not to compete with a then existing
business opportunity of DASA-RI in Europe.

     2.5 As part of its  consideration  of any  commercial  opportunity  for the
parties  falling within the Exclusive  Common  Business  Segments (other than in
cases  where one party is acting in the  capacity of a  contractor  to the other
party pursuant to Section  2.4.3),  the Committee  shall  determine the parties'
respective  ownership of intellectual  property  interests  (including rights to
seek patent  protection) in any technology which will be jointly  developed as a
result of the parties' engagement in the commercial opportunity.

     2.6 In their  consideration  of new  commercial  opportunities  within  the
Exclusive Common Business Segments, the parties,  acting through their appointed
members on the Committee,  shall work in good faith to reach consensus.  Neither
party  shall be  entitled  to  abstain  from  good  faith  consideration  of any
opportunity  brought before the Committee or deliberately to block or hinder the
achievement of consensus on any such issue.

     2.7 The Spacehab  Executive  Committee  and/or  Board of Directors  and the
DASA-RI  Board of  Management  shall  have  final  authority  on  behalf  of the
respective party hereto to accept or reject any major determination by the Joint
Management  Committee,  including  any financial  commitments  required from the
parties  hereto,  but they  shall have no  authority  to alter or amend any such
determination.

     3. Executive  Exchange  Program.  Both parties agree to exchange  executive
level representatives of their companies for a period of up to three months each
with the goal to achieve a better  understanding of each other's  structures and
processes and thereby to optimize the efficiency of the collaboration.

     4. Term.

     4.1 The term of this Agreement shall commence concurrently with the initial
closing  of the  Subscription  Agreement  and shall  remain in effect  until the
earliest of the following:


                                      -5-

this  Agreement,  upon sixty (60) days prior written  notice of  termination  by
either party (the "Notifying Party") to the other (the "Notified Party");

     (b) In the event that the DASA-RI  Minimum Revenue is not met in 2001 or in
2002,  upon thirty (30) days prior written  notice of  termination by DASA-RI to
Spacehab; or

     (c) In the event  that the  DASA-RI  Minimum  Contract  Award is not met by
December 31, 2000,  upon thirty (30) days prior written notice of termination by
DASA-RI to Spacehab;

     (d)  Immediately  upon written notice of termination by the Notifying Party
in the event the Notified Party breaches any material  undertaking  hereunder or
in the Subscription  Agreement and fails to cure such breach within fifteen (15)
days of receiving notice of default from the Notifying Party.

     4.2 In the event of termination of this Agreement pursuant to paragraph (a)
above,  the parties will promptly enter into good faith  negotiations to reach a
mutual agreement on the  discontinuation  of joint projects and they will ensure
that ongoing  contractual  obligations  toward third parties are  professionally
fulfilled or wound up.

                  DESIGNATION OF RIGHTS, TERMS AND PREFERENCES
                                       OF
                   SERIES B SENIOR CONVERTIBLE PREFERRED STOCK
                                       OF
                             SPACEHAB, INCORPORATED

                          (Pursuant to Chapter 6 of the
                      Washington Business Corporation Act)



     Spacehab, Incorporated, a corporation organized and existing under the
Business Corporation Act of the State of Washington (hereinafter called the
"Corporation"), hereby certifies that the following resolution was adopted by
the Board of Directors of the Corporation as required by Chapter 6 of the
Business Corporation Act at a meeting duly called and held on July 13, 1999:

          RESOLVED, that pursuant to the authority granted to and vested in the
     Board of Directors of this Corporation (hereinafter called the "Board of
     Directors" or the "Board") in accordance with the provisions of the
     Articles of Incorporation, the Board of Directors hereby creates a series
     of Preferred Stock of the Corporation, no par value per share (the
     "Preferred Stock"), and hereby states the designation and number of shares,
     and fixes the relative rights, preferences, and limitations thereof as
     follows:

          Series B Senior Convertible Preferred Stock:

     Section 1. Designation and Amount. The shares of such series shall be
designated as "Series B Senior Convertible Preferred Stock" (the "Series B
Preferred Stock") and the number of shares constituting the Series B Preferred
Stock shall be Nine Hundred Seventy-Five Thousand (975,000). Such number of
shares may be decreased by resolution of the Board of Directors; provided that
no decrease shall reduce the number of shares of Series B Preferred Stock to a
number less than the number of shares then outstanding.

     Section 2. Dividends. The holders of the Series B Preferred Stock shall be
entitled to receive, out of funds legally available therefor, such dividends
with respect to the shares of Series B Preferred Stock as may be declared by the
Board of Directors. In addition, when and if the Board of Directors shall
declare a dividend payable with respect to the then outstanding shares of Common
Stock, no par value per share ("Common Stock") of the Corporation, each holder
of Series B Preferred Stock shall be entitled to the amount of dividends as
would be payable on the largest number of whole shares of Common Stock into
which shares of Series B Preferred Stock held by such holder could then be
converted pursuant to Section 5 hereof (such number to be determined as of the
record date for the determination of holders of Common Stock entitled to receive
such



<PAGE>

dividend). Dividends shall not be declared or paid to holders of Common Stock
unless and until the Corporation shall simultaneously declare and pay to holders
of Series B Preferred Stock the dividend referred to in the preceding sentence.

     Section 3. Liquidation, Dissolution or Winding Up; Certain Mergers,
Consolidations and Asset Sales.

          a. In the event of any voluntary or involuntary liquidation,
     dissolution or winding up of the Corporation, the holders of shares of
     Series B Preferred Stock then outstanding shall be entitled to be paid out
     of the assets of the Corporation available for distribution to its
     stockholders, before any payment shall be made to the holders of Common
     Stock or any other class or series of stock ranking on liquidation junior
     to the Series B Preferred Stock (the Common Stock and any other class or
     series of stock ranking on liquidation junior to the Series B Preferred
     Stock, including without limitation, the Series A Junior Participating
     Preferred Stock of the Corporation, being collectively referred to as
     "Junior Stock") by reason of their ownership thereof, an amount equal to
     Nine Dollars ($9.00) for each outstanding share of Series B Preferred Stock
     (the "Series B Original Issue Price")(subject to appropriate adjustment in
     the event of any stock dividend, stock split, combination or other similar
     recapitalization affecting such shares) plus (ii) any dividends declared or
     accrued but unpaid thereon. If upon any such liquidation, dissolution or
     winding up of the Corporation, the remaining assets of the Corporation
     available for distribution to its stockholders shall be insufficient to pay
     the holders of shares of Series B Preferred Stock the full amount to which
     they shall be entitled, the holders of shares of Series B Preferred Stock
     and any class or series of stock ranking on liquidation on a parity with
     the Series B Preferred Stock shall share ratably (based upon the sum of
     each series respective Original Issue Price plus accrued but unpaid
     dividends) in any distribution of the remaining assets and funds of the
     Corporation in proportion to the respective amounts which would otherwise
     be payable in respect of the shares held by them upon such distribution if
     all amounts payable on or with respect to such shares were paid in full.

          b. After the payment of all preferential amounts required to be paid
     to the holders of Series B Preferred Stock and any other class or series of
     stock of the Corporation ranking on liquidation on a parity with the Series
     B Preferred Stock upon the dissolution, liquidation or winding up of the
     Corporation, the holders of shares of Junior Stock then outstanding shall
     be entitled to receive the remaining assets and funds of the Corporation
     available for distribution to its stockholders.

          c. The consolidation or merger of the Corporation into or with any
     other entity or entities which results in the exchange of outstanding
     shares of the Corporation for securities or other consideration issued or
     paid or caused to be issued or paid by any such entity or affiliate
     thereof, and the sale or transfer by the Corporation of all or
     substantially all its assets, shall be deemed to be a liquidation,
     dissolution or winding up of the Corporation within the meaning of the
     provisions of this Section 3, but only for the purposes of the redemption
     of such Series B Preferred Stock, and only if so elected by the holders of
     a majority of the outstanding shares of Series B Preferred Stock, in their
     sole discretion.

                                       2

<PAGE>

     Section 4. Voting.

          a. Each holder of outstanding shares of Series B Preferred Stock shall
     be entitled to the number of votes equal to the number of whole shares of
     Common Stock into which the shares of Series B Preferred Stock held by such
     holder are then convertible (as adjusted from time to time pursuant to
     Section 5 hereof), at each meeting of stockholders of the Corporation (and
     written actions of stockholders in lieu of meetings) with respect to any
     and all matters presented to the stockholders of the Corporation for their
     action or consideration. Except as provided by law, or by the provisions of
     Subsections 4(b), 4(c) and 4(d) below, holders of Series B Preferred Stock
     shall vote together with the holders of Common Stock, as a single class.

          b. For so long as (i) any shares of Series B Preferred Stock remain
     outstanding and (ii) any holder thereof is a Qualified Holder (as defined
     in the Preferred Stock Purchase Agreement (the "Purchase Agreement") dated
     as of August 2, 1999 between the Corporation and Daimler Chrysler Aerospace
     AG ("DASA")), the Series B Preferred Stock (voting as a class) will elect
     one of the Directors (the "Preferred Director") and the Common Stock
     (voting as a class) will elect the remaining Directors. The Preferred
     Director shall be included as a member of the Executive Committee of the
     Board. If at any time Series B Preferred Stock issued remains outstanding
     but there is no Qualified Holder, all of the Directors will be elected by
     the Series B Preferred Stock and Common Stock voting together as one class.
     This Section 4(b) shall not affect or limit provisions of Section 8.1 of
     the Purchase Agreement as to the right of a Qualified Holder to designate a
     nominee for election to the Board (and for such designee, if elected by the
     shareholders, to serve on the Executive Committee of the Board), which
     provisions may remain applicable notwithstanding there not being any shares
     of Series B Preferred Stock outstanding.

          c. Any Preferred Director may be removed at any time, by the vote of
     the holders of more than fifty percent (50%) of all of the then outstanding
     shares of Series B Preferred Stock, voting as a separate class in person or
     by proxy at a special meeting of stockholders called for such purpose (or
     at any adjournment thereof) by holders of at least twenty percent (20%) of
     the outstanding shares of Series B Preferred Stock or at any annual meeting
     of stockholders, or by written consent delivered to the Secretary of the
     Corporation, and no Preferred Director may be removed at any time without
     the affirmative vote or consent of the holders of more than fifty percent
     (50%) of all of the outstanding shares of Series B Preferred Stock. Any
     vacancy created by the removal, death or resignation of a Preferred
     Director may be filled by the holders of more than fifty percent (50%) of
     all of the outstanding shares of Series B Preferred Stock by vote in person
     or by proxy at a special meeting of stockholders of the Corporation called
     for such purpose by holders of at least twenty percent (20%) of the
     outstanding shares of Series B Preferred Stock, or at any annual meeting,
     or by written consent delivered to the Secretary of the Corporation.

          d. So long as any shares of the Series B Preferred Stock remain
     outstanding, unless the vote or consent of the holders of a greater number
     of shares shall then be required by law, the affirmative vote or consent of
     the holders of more than fifty

                                       3

<PAGE>

     percent (50%) of all of the shares of Series B Preferred Stock at the time
     outstanding, voting separately as a class, given in person or by proxy
     either in writing (as may be permitted by law and the Articles of
     Incorporation and By-laws of the Corporation) or at any special or annual
     meeting, shall be necessary to permit, effect or validate the taking of any
     of the following actions by the Corporation:

               (i) create, authorize, issue or sell (i) any class or series of
          capital stock ranking prior to or on parity with the Series B
          Preferred Stock as to dividends or upon liquidation, dissolution or
          winding up; provided, however, that holders of Common Stock may
          receive dividends to the extent provided by Section 2 above and,
          provided further, that the consent to issuance of any class or series
          of capital stock ranking on parity with the Series B Preferred Stock
          shall not be unreasonably withheld; or (ii) any rights, options or
          other securities convertible, exercisable or exchangeable for or into,
          or having rights to purchase, any shares of capital stock described in
          clause (i) hereof; or

               (ii) amend the Articles of Incorporation or By-laws of the
          Corporation, or in any other manner alter or change the powers,
          rights, privileges or preferences of the Series B Preferred Stock, if
          such amendment or action would alter, change or affect adversely the
          powers, rights, privileges or preferences of the holders of the Series
          B Preferred Stock; or

               (iii) increase the number of shares of Series B Preferred Stock
          authorized for issuance above 1,333,334 shares; or

               (iv) at any time after the initial issuance date of the Series B
          Preferred Stock, issue any shares of Series B Preferred Stock, except
          (i) issuances pursuant to the Purchase Agreement, or (ii) issuances of
          share certificates upon transfers or exchanges of shares by holders
          (other than the Corporation) or in replacement of lost, stolen,
          damaged or mutilated share certificates;

     Section 5. Optional Conversion. The holders of the Series B Preferred Stock
shall each have conversion rights as follows (the "Conversion Rights"):

          a. Right to Convert. Shares of Series B Preferred Stock shall be
     convertible, at the option of the holder thereof, at any time and from time
     to time, and without the payment of additional consideration by the holder
     thereof, into such number of fully paid and nonassessable shares of Common
     Stock as is determined by dividing the aggregate Series B Original Issue
     Price of the Shares of Series B Preferred Stock being converted by the
     Series B Conversion Price in effect at the time of conversion or such
     share. The initial "Series B Conversion Price" shall be Nine Dollars
     ($9.00), subject to adjustment as provided below. For purposes of this
     Section 5, "Original Issue Date" shall mean, for the Series B Preferred
     Stock, the date on which the first share of Series B Preferred Stock was
     issued.

          In the  event of a  liquidation  of the  Corporation,  the  Conversion
     Rights  shall  terminate  at the close of  business  on the first  full day
     preceding the date

                                       4

<PAGE>

     fixed for the payment of any amounts  distributable  on  liquidation to the
     holders of Series B Preferred Stock.

          b. Fractional Shares. No fractional shares of Common Stock shall be
     issued upon conversion of the Series B Preferred Stock, and the number of
     shares of Common Stock to be issued shall be rounded to the nearest whole
     share. The shares issuable upon such conversion shall be determined on the
     basis of the total number of shares of Series B Preferred Stock which the
     holder is at the time converting into Common Stock and the number of shares
     of Common Stock issuable upon such aggregate conversion.

          c. Mechanics of Conversion.

               (i) In order for a holder of Series B Preferred Stock to convert
          shares of Series B Preferred Stock into shares of Common Stock, such
          holder shall surrender the certificate or certificates for such shares
          of Series B Preferred Stock, at the office of the transfer agent for
          the Corporation (or at the principal office of the Corporation if the
          Corporation serves as its own transfer agent), together with written
          notice that such holder elects to convert all or any number of the
          shares of the Series B Preferred Stock represented by such certificate
          or certificates. Such notice shall state such holder's name or the
          names of the nominees in which such holder wishes the certificate or
          certificates for shares of Common Stock to be issued. If required by
          the Corporation, certificates surrendered for conversion shall be
          endorsed or accompanied by a written instrument or instruments of
          transfer, in form satisfactory to the Corporation, duly executed by
          the registered holder or his, her or its attorney duly authorized in
          writing. The date of receipt of such certificates and notice by the
          transfer agent (or by the Corporation if the Corporation serves as its
          own transfer agent) shall be the conversion date ("Conversion Date").
          The Corporation shall, as soon as practicable after the Conversion
          Date, issue and deliver at such office to such holder of Series B
          Preferred Stock, or to his, her or its nominees, a certificate or
          certificates for the number of shares of Common Stock to which such
          holder shall be entitled, together with cash in lieu of any fraction
          of a share. In case less than all the shares of Series B Preferred
          Stock represented by any certificate are being converted, a new
          certificate representing the unconverted shares of Series B Preferred
          Stock shall be issued to the holder thereof without cost to such
          holder.

               (ii) The Corporation shall at all times when the Series B
          Preferred Stock shall be outstanding, reserve and keep available out
          of its authorized but unissued stock, for the purpose of effecting the
          conversion of the Series B Preferred Stock, such number of its duly
          authorized shares of Common Stock as shall from time to time be
          sufficient to effect the conversion of all outstanding Series B
          Preferred Stock.

               (iii) Upon any such conversion, no adjustment to the Series B
          Conversion Price shall be made for any declared or accrued but unpaid
          dividends on the Series B Preferred Stock surrendered for conversion
          or on the Common Stock delivered upon conversion, but, as provided in
          clause (iv) below, such dividends shall remain payable to the holder
          thereof.

                                       5

<PAGE>

               (iv) All shares of Series B Preferred Stock which shall have been
          surrendered for conversion as herein provided shall no longer be
          deemed to be outstanding and all rights with respect to such shares,
          including the rights, if any, to receive notices and to vote, shall
          immediately cease and terminate on the Conversion Date, except only
          the right of the holders thereof to receive shares of Common Stock in
          exchange therefor and payment of any dividends declared or accrued but
          unpaid thereon. Any shares of Series B Preferred Stock so converted
          shall be retired and cancelled and shall not be reissued, and the
          Corporation (without the need for stockholder action) may from time to
          time take such appropriate action as may be necessary to reduce the
          authorized Series B Preferred Stock accordingly.

               (v) The Corporation shall pay any and all issue and other taxes
          that may be payable in respect of any issuance or delivery of shares
          of Common Stock upon conversion of shares of Series B Preferred Stock
          pursuant to this Section 5. The Corporation shall not, however, be
          required to pay any tax which may be payable in respect of any
          transfer involved in the issuance and delivery of shares of Common
          Stock in a name other than that in which the shares of Series B
          Preferred Stock so converted were registered, and no such issuance or
          delivery shall be made unless and until the person or entity
          requesting such issuance has paid to the Corporation the amount of any
          such tax or has established, to the satisfaction of the Corporation,
          that such tax has been paid.

          d. Adjustment for Stock Splits and Combinations. If the Corporation
     shall at any time or from time to time after the Original Issue Date of the
     Series B Preferred Stock effect a subdivision of the outstanding Common
     Stock, the Series B Conversion Price then in effect with respect to the
     Series B Preferred Stock immediately before that subdivision shall be
     proportionately decreased. If the Corporation shall at any time or from
     time to time after the Original Issue Date of the Series B Preferred Stock
     combine the outstanding shares of Common Stock, the Series B Conversion
     Price then in effect immediately before the combination with respect to the
     Series B Preferred Stock shall be proportionately increased. Any adjustment
     under this paragraph shall become effective at the close of business on the
     date the subdivision or combination becomes effective.

          e. Adjustment for Certain Dividends and Distributions. In the event
     the Corporation at any time, or from time to time after the Original Issue
     Date of the Series B Preferred Stock shall make or issue, or fix a record
     date for the determination of holders of Common Stock entitled to receive,
     a dividend or other distribution payable in additional shares of Common
     Stock, then and in each such event the Series B Conversion Price with
     respect to the Series B Preferred Stock then in effect shall be decreased
     as of the time of such issuance or, in the event such a record date shall
     have been fixed, as of the close of business on such record date, by
     multiplying the Series B Conversion Price for the Series B Preferred Stock
     then in effect by a fraction:

          (1) the numerator of which shall be the total number of shares of
     Common Stock issued and outstanding immediately prior to the time of such
     issuance or the close of business on such record date, and

                                       6

<PAGE>

          (2) the denominator of which shall be the total number of shares of
     Common Stock issued and outstanding immediately prior to the time of such
     issuance or the close of business on such record date plus the number of
     shares of Common Stock issuable in payment of such dividend or
     distribution;

     provided, however, that if such record date shall have been fixed and such
     dividend is not fully paid or if such distribution is not fully made on the
     date fixed therefor, the Series B Conversion Price for the Series B
     Preferred Stock shall be recomputed accordingly as of the close of business
     on such record date and thereafter the Series B Conversion Price for the
     Series B Preferred Stock shall be adjusted pursuant to this paragraph as of
     the time of actual payment of such dividends or distributions.

          f. Adjustments for Other Dividends and Distributions. In the event the
     Corporation at any time or from time to time after the Original Issue Date
     of the Series B Preferred Stock shall make or issue, or fix a record date
     for the determination of holders of Common Stock entitled to receive, a
     dividend or other distribution payable in securities of the Corporation
     other than shares of Common Stock, then and in each such event provision
     shall be made so that the holders of Series B Preferred Stock shall receive
     upon conversion thereof in addition to the number of shares of Common Stock
     receivable thereupon, the amount of securities of the Corporation that they
     would have received had the Series B Preferred Stock been converted into
     Common Stock on the date of such event and had thereafter, during the
     period from the date of such event to and including the conversion date,
     retained such securities receivable by them as aforesaid during such
     period, giving application to all adjustments called for during such period
     under this paragraph with respect to the rights of the holders of the
     Series B Preferred Stock.

          g. Adjustment for Reclassification, Exchange or Substitution. If the
     Common Stock issuable upon the conversion of the Series B Preferred Stock
     shall be changed into the same or a different number of shares of any class
     or classes of stock, whether by capital reorganization, reclassification,
     or otherwise (other than a subdivision or combination of shares or stock
     dividend provided for above, or a reorganization, merger, consolidation, or
     sale of assets provided for below), then and in each such event the holders
     of the Series B Preferred Stock shall have the right thereafter to convert
     such share into the kind and amount of shares of stock and other securities
     and property receivable upon such reorganization, reclassification, or
     other change, by holders of the number of shares of Common Stock into which
     such shares of Series B Preferred Stock might have been converted
     immediately prior to such reorganization, reclassification, or change, all
     subject to further adjustment as provided herein.

          h. Adjustment for Merger or Reorganization, etc. In case of any
     consolidation or merger of the Corporation with or into another corporation
     or the sale of all or substantially all of the assets of the Corporation to
     another corporation (other than a consolidation, merger or sale which is
     covered by Subsection 3(c)), each share of Series B Preferred Stock shall
     thereafter be convertible (or shall be converted into a security which
     shall be convertible) into the kind and amount of shares of stock or other
     securities or property to which a holder of the number of shares of Common
     Stock of the Corporation deliverable upon conversion of such Series B
     Preferred Stock would have

     Directors) shall be made in the application of the provisions in this
     Section 5 set forth with respect to the rights and interest thereafter of
     the holders of the Series B Preferred Stock, to the end that the provisions
     set forth in this Section 5 (including provisions with respect to changes
     in and other adjustments of the Series B Conversion Price) shall thereafter
     be applicable, as nearly as reasonably may be, in relation to any shares of
     stock or other property thereafter deliverable upon the conversion of the

     assets, consolidation, merger, dissolution, issue or sale of securities or
     any other voluntary action, avoid or seek to avoid the observance or
     performance of any of the terms to be observed or performed hereunder by
     the Corporation, but will at all times in good faith assist in the carrying
     out of all the provisions of this Section 5 and in the taking of all such
     action as may be necessary or appropriate in order to protect the
     respective Conversion Rights of the holders of the Series B Preferred Stock
     against impairment.

          j. Certificate as to Adjustments. Upon the occurrence of each
     adjustment or readjustment of the Series B Conversion Price pursuant to
     this Section 5, the Corporation at its expense shall promptly compute such
     adjustment or readjustment in accordance with the terms hereof and furnish
     to each holder of Series B Preferred Stock a certificate setting forth such
     adjustment or readjustment and showing in detail the facts upon which such
     adjustment or readjustment is based. The Corporation shall, upon the
     written request at any time of any holder of Series B Preferred Stock,
     furnish or cause to be furnished to such holder a similar certificate
     setting forth (i) such adjustments and readjustments, (ii) the Series C
     Conversion Price then in effect, and (iii) the number of shares of Common
     Stock and the amount, if any, of other property which then would be
     received upon the conversion of such Series B Preferred Stock.

                    Corporation (other than a subdivision or combination of its
                    outstanding shares of Common Stock or a stock dividend or
                    stock distribution thereon), or of any consolidation or
                    merger of the Corporation into or with another corporation,

                    merger, sale, dissolution, liquidation or winding up is
                    expected to become effective, and the date as of which it is
                    expected that holders of Common Stock of record shall be
                    entitled to exchange their shares of Common Stock for
                    securities or other property deliverable upon such
                    reclassification, consolidation, merger, sale, dissolution
