Item 5.  Other Events.

         On August 5, 1999, Spacehab, Incorporated (the "Company") issued
975,000 shares of a new Series B Senior Convertible Preferred Stock (the "Series
B Preferred Stock") and agreed to issue an additional 358,334 shares of the
Series B Preferred Stock following an amendment to its Articles of Incorporation
to permit an increase in the number of authorized shares of preferred stock.
This amendment will be presented to stockholders at their Annual Meeting
scheduled for October 14, 1999.

         The purchaser of the Series B Preferred Stock is DaimlerChrysler
Aerospace AG and the total consideration to be paid is $12 million, assuming all
1,333,334 shares of Series B Preferred are issued.

         The Preferred Stock is entitled to dividends as declared by the
Company's Board of Directors, and the Company may pay dividends upon its Common
Stock only if the Preferred Stock will participate equally in any such dividend.
The Preferred Stock will rank senior to the Common Stock of the Company as to
dividends and distributions upon liquidation, dissolution or winding up of the
Company, and will be entitled, prior and in preference to any distribution to
the holders of Common Stock, to be paid $9 per share of Preferred Stock upon
such liquidation, dissolution or winding up of the Company.

         The Preferred Stock is convertible into shares of the Company's Common
Stock on a one for one basis, subject to anti-dilution provisions.

         The Preferred Stock will be entitled to an equal number of votes as the
number of shares of the Company's Common Stock into which such Preferred Stock
is then convertible on all matters except the election of directors. The
Preferred Stock is entitled, voting separately as a class, to elect one director
of the Company.

         The above summary is qualified in its entirety by the terms and
provisions of the exhibits filed with this Current Report on Form 8-K.

                             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>   2
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>   3
         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>   4
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>   5
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>   6
                     (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>   7
                  (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


                                       7
<PAGE>   8
been entitled upon such consolidation, merger or sale; and, in such case,
appropriate adjustment (as determined in good faith by the Board of 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 Series B Preferred Stock.

                  i. No Impairment. The Corporation will not, by amendment of
its Articles of Incorporation, or through any reorganization, transfer of
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.

                  k. Notice of Record Date. In the event:

                     (a)    that the Corporation declares a dividend (or any
                            other distribution) on its Common Stock payable in
                            Common Stock or other securities of the corporation;

                     (b)    that the Corporation subdivides or combines its
                            outstanding shares of Common 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, or of the sale of all or
                            substantially all of the assets of the Corporation;
                            or


                                       8

                           liquidation or winding up of the Corporation;

then the Corporation shall cause to be filed at its principal office, and shall

                  to such dividend, distribution, subdivision or combination are
                  to be determined, or

         (ii)     the date on which such reclassification, consolidation,

         (a) The Company and each Subsidiary is a corporation duly organized,
validly existing and in good standing under the laws of its state or other
jurisdiction of incorporation. The Company and each Subsidiary is duly
qualified, licensed and authorized to do business and is in good standing in
each jurisdiction in which it owns or leases any material property or in which
the conduct of its business requires it to be so qualified or licensed.

         (b) No proceeding has been commenced looking toward the dissolution or
merger of the Company or any Subsidiary. Except as contemplated by this
Agreement, no proceeding has been commenced looking toward the amendment of the
respective certificate or articles of incorporation of the Company or any

violation in any respect of its certificate or articles of incorporation or
by-


                                       13

laws.

         (c) The Company and each Subsidiary has all requisite power, authority

         (d) The Company has all requisite power, authority (corporate and
other) and legal right to execute, deliver, enter into, consummate and perform
the transactions contemplated by this Purchase Agreement and each Other
Transaction Document (including without limitation the issuance by the Company
of the Shares). The execution, delivery and performance by the Company of this
Purchase Agreement and each Other Transaction Document (including without

any preemptive rights with respect to any issuance of capital stock. On each
Closing Date, no other shares of capital stock of the Company will be

encumbrances, and entitled to be traded on the National Association of

beneficially and of record by the Company free and clear of all Liens, options
or claims of any kind. There are no outstanding options, warrants,

incorporation or by-laws of the Company or any of its Subsidiaries or (B) any
law, rule, regulation or order of any Governmental Authority, or any order,
judgment, writ, injunction, decree, award or other action of any court or

         5.5      Disclosure Materials: Other Information.

         (a) The Company has previously furnished to Purchaser the following
material (the "Disclosure Material"): (i) audited consolidated financial
statements of the Company and its Subsidiaries consisting of consolidated
balance sheets as at June 30, 1998 and June 30, 1997 and the related
consolidated statements of income, changes in shareholders' equity and cash
flows for the fiscal years ended June 30, 1998 and June 30, 1997 and the nine
months ended June 30, 1996 and the related notes thereto, all of which
statements have been certified by KPMG Peat Marwick LLP, independent certified
public accountants; (ii) unaudited consolidated financial statements of the
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;
(iii) the other financial information described in Schedule 5.5(a)(iii); and
(iv) the Company's Form 10-K for the year ended June 30, 1998, Form 10-Q for the
fiscal quarters ended September 30, 1998, December 31, 1998 and March 31, 1999
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
since the time


                                       16
<PAGE>   17
of filing). The audited and unaudited financial statements referred to in the
preceding clauses (i) and (ii) above (including in each case the related notes
and schedules) fairly present the financial condition of the Company and its
Subsidiaries as of the respective dates thereof and the results of the
operations of the Company and its Subsidiaries for such periods and have been
prepared in accordance with GAAP, except that any such unaudited statements may
omit notes and may be subject to normal year-end adjustments.

         (b) Since March 31, 1999, (i) the business of the Company and its
Subsidiaries has been conducted in the ordinary course and (ii) except as set
forth in Schedule 5.5, there has occurred no event that could reasonably be
expected to have a Material Adverse Effect.

         (c) Neither the Company nor any Subsidiary is aware of any obligations
or liabilities, contingent or otherwise (including without limitation any tax

statements referred to in Section 5.5(a) above or otherwise disclosed in
Schedule 5.5 hereto, other than liabilities arising in the ordinary course of
business subsequent to March 31, 1999, none of which would have a Material
Adverse Effect.

         (d) The Company has filed all required reports, schedules, forms,
statements and other documents with the Commission since June 30, 1998 (such
reports, schedules, forms, statements and other documents, together with all
registration statements filed by the Company or its Subsidiaries with the
Commission since June 30, 1998, in each case, as such documents have been
amended since the time of their filing) (all such documents referred to herein
as the "SEC Documents"). As of their respective filing dates (or, if amended, as
of the date of the filing of such amendment), the SEC Documents complied in all
material respects with the requirements of the Securities Act or the Exchange
Act, as the case may be, and the rules and regulations of the Commission
promulgated thereunder applicable to such SEC Documents. None of the SEC
Documents as of such dates contained any untrue statement of a material fact or
omitted to state a material fact required to be stated therein or necessary in
order to make the statements therein, in light of the circumstances under which
they were made, not misleading.

         (e) The financial information referred to in Section 5.5(a)(iii) was
prepared in good faith and the Company reasonably believes that as of the
respective dates of their preparation there was a reasonable basis for such
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.

         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
to be, but has not previously been, described in any filing by the Company with
the Commission. The Company has no knowledge of any unasserted claim that, if
asserted, could have a Material Adverse Effect.

         5.7      Taxes.

with all Governmental Authorities required to be filed by it and all such
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 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

prospective transferee any financial or other information concerning the Company
and its Subsidiaries which is required to be delivered by


                                       26
<PAGE>   27

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
result of (i) any misrepresentation in or breach any of the representations and
warranties of the Company contained in this Agreement or in any Other
Transaction Documents or (ii) any breach of, or failure to perform, any
agreement or covenant of the Company contained in this Agreement or any of the

for an


                                       27
<PAGE>   28
injunction against a violation of any of the terms hereof or thereof or in aid

other remedy (including without limitation damages).

         (c) No course of dealing and no delay on the part of any party to this
Purchase Agreement in exercising any rights or remedies shall operate as a

equity, by statute or otherwise.

         (d) Purchaser shall, in addition to other remedies provided by law,

required, under any applicable state securities laws, (ii) such Shares or
underlying Common Stock are sold in accordance with the applicable requirements
and limitations of Rule 144 or Rule 144A or another exemption from registration
and any applicable state securities laws, (iii) if the Company has so requested,
the Company has been furnished with an opinion, in form and substance reasonably
satisfactory to the Company, from counsel to Purchaser to the effect that
registration under the Securities Act is not required for the transfer as
proposed (provided that such opinion may be conditioned upon the transferee's
assuming the obligations of a holder of Shares or underlying Common Stock under
this Section) or (iv) the Company has been furnished with a letter from the
Division of Corporate Finance of the Commission to the effect that such Division
would not recommend any action to the Commission if such proposed transfer were
effected without a registration statement effective under the Securities Act.
The Company agrees that within five (5) Business Days after receipt of any
opinion referred to in (iii) above, it will notify the holder supplying such
opinion whether such opinion is satisfactory to the Company's counsel.

         (b) The Company may endorse on all Share (or underlying Common Stock)
certificates a legend stating or referring to the transfer restrictions
contained in paragraph (a) above provided, that no such legend shall be endorsed
on any certificates which, when issued, are no longer subject to the
restrictions of this Section 11; provided, further, that if a transfer is made
pursuant to Rule 144 or clause (i) or clause (iv) of paragraph (a) of this
Section 11 or if an


                                       28
<PAGE>   29
opinion of counsel provided pursuant to clause (iii) of paragraph (a) concludes
that the legend is no longer necessary, the Company will deliver upon transfer
certificates without such legends.

REGISTRATION RIGHTS AGREEMENT, dated as of August 5, 1999, between Spacehab,
Incorporated, a Washington corporation (the "Company"), and DaimlerChrysler
Aerospace AG, a German corporation ("Purchaser"). Capitalized terms used but not
otherwise defined herein shall have the meanings assigned to such terms in the
Purchase Agreement dated August 2, 1999, between the Company and Purchaser (the
"Purchase Agreement").

                              W I T N E S S E T H:

         WHEREAS, pursuant to the Purchase Agreement, Purchaser is investing in
shares of Series B Convertible Preferred Stock, no par value (the "Preferred
Stock"), of the Company, which Preferred Stock is convertible into shares of
Common Stock, no par value ("Common Stock") of the Company, all on the terms and
subject to the conditions therein set forth; and

         WHEREAS, the Purchase Agreement contemplates the execution and delivery
of this Agreement contemporaneously therewith;

         NOW, THEREFORE, in connection with the Purchase Agreement and for the
other good and valuable consideration, the receipt and sufficiency of which is
hereby 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,
association, joint venture, trust or unincorporated organization, or a
government, governmental body, court, or any agency or political subdivision
thereof.

         "Registered", "registered" or "registration" refer to a registration
effected by preparing and filing a registration statement or similar document in
compliance with the Securities Act, and the declaration or ordering of
effectiveness of such registration statement or document.

         "Registrable Securities" means (i) the shares of Common Stock
obtainable upon
<PAGE>   2
conversion of Preferred Stock, (ii) the shares of Common Stock outstanding from
any previous conversion of Preferred Stock and (iii) 104,165 shares of Common
Stock owned by Purchaser prior to its purchase of Preferred Stock. Once a Holder
sells Registrable Securities pursuant to a registration statement or Rule 144
under the Securities Act, they shall no longer be deemed to be Registrable
Securities.

         "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
Securities under circumstances requiring registration under the Securities Act
and requesting that the Company effect registration with respect to such
Registrable Securities.

         "Securities Act" means the Securities Act of 1933, 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.

         Section 2.    Registration Rights.

         (a) Demand Registration Rights. At any time after the first anniversary
of 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
registration under this Section 2(a). Any Holder may exercise such option by
delivering written notice of exercise to the Company within thirty (30) days
after receiving notice from the Company of the proposed registration. Any such
notice to the Company shall specify the number of Registrable Securities to be
included in such registration and the Company shall be obligated to include such
Registrable Securities in any such registration.

         (b) Number of Demand Registrations. Subject to the terms and conditions
hereof, the Holders shall be entitled to request (and the Company shall be
required to effect) up to four (4) registrations under the Securities Act of all
or part of the Registrable Securities. For purposes hereof, if (i) the Company
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


                                       2
<PAGE>   3
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
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


                                       3
<PAGE>   4
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 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


                                       4
<PAGE>   5
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 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


                                       5
<PAGE>   6
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.

         (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


                                       6
<PAGE>   7
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.

         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


                                       7
<PAGE>   8
         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 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


                                       8
<PAGE>   9
         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 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


                                       9
<PAGE>   10
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.

         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.


                                       10
<PAGE>   11
         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 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


                                       11

RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING TO

                                       12
<PAGE>   13
represents and warrants, severally and not jointly, that (i) it has all
necessary power and has taken all necessary action to make all the provisions of
the Agreement the valid and binding obligation of the undersigned and
enforceable in accordance with its terms; and (ii) the Agreement is a legal,
valid and binding obligation of the undersigned enforceable in accordance with

         (d) Binding Effect, Benefit and Assignment. The terms of this Agreement
shall be binding upon, and inure to the benefit of, the parties and their
respective successors and permitted assigns whether so expressed or not. The
Company may not assign any of its obligations, duties or rights under this
Agreement except with the consent of each Holder. In addition to any assignment
by operation of law, (i) each Holder may assign, in whole or in part, any or all
of its rights (and/or obligations) under this Agreement to any person, provided

DAIMLERCHRYSLER AEROSPACE TO BUY
$12 MILLION EQUITY STAKE IN SPACEHAB, INC.
German Aerospace Giant's Ownership in U.S. Commercial Space Leader to Increase
to 11.5%

Washington, D.C., August 2, 1999 - SPACEHAB, Inc. (Nasdaq: SPAB) today announced
that Munich-based DaimlerChrysler Aerospace AG (Dasa) is buying a $12 million
equity stake in the Washington-based commercial space services provider. Dasa
has agreed to purchase 1.33 million shares of preferred stock. The preferred
stock, convertible on a one-for-one basis into common stock, will increase
Dasa's investment interest in SPACEHAB to approximately 11.5%.

         Dasa, which is the aerospace subsidiary of DaimlerChrysler, already
owned one percent of SPACEHAB's outstanding common stock and the two companies
enjoy a close working relationship. Dasa is a subcontractor on SPACEHAB's
Integrated Cargo Carrier program, which was used by NASA to deliver
unpressurized cargo to the International Space Station (ISS) during Discovery
mission STS-96 in May.

         The increase of equity by Dasa in SPACEHAB expands and solidifies that
relationship as both companies pursue opportunities related to commercial
resupply and utilization of the ISS. Recently, Dasa's Space Infrastructure
Division took over leadership in the initiative to industrialize operations and
utilization of Europe's share in the ISS by submitting a proposal to the
European Space Agency (ESA). Among various others, one potential area of
cooperation is an advanced orbital propulsion system related to ISS servicing
and station-based science and research.

         "As prime contractor to ESA for Europe's core contributions for the
ISS-D the Columbus laboratory and the Russian Data Management System - and
focusing on an essential role in Space Station operations and utilization, Dasa
felt it was important to strengthen our strategic relationship with SPACEHAB by
expanding our ownership position", said Josef Kind, President of Dasa's Space
infrastructure Division.

         "Dasa's additional investment in SPACEHAB reinforces the view that
SPACEHAB is a key player in the ISS program and is a model for other commercial
companies hoping to resupply and utilize the ISS," said SPACEHAB Chairman and
CEO Dr. Shelley A. Harrison. "We are especially excited about expanding our
cooperation with one of the leading players in the European space industry."

         Under the stock purchase agreement approved today, Dasa will
immediately purchase all of SPACEHAB's 975,000 authorized and unissued preferred
shares. The other 358,333 shares will be issued upon shareholder approval of a
proposal to increase the number of authorized preferred shares that will be
presented at the next shareholders meeting in October. Mr. Josef Kind of Dasa
will join SPACEHAB's Board of Directors, representing the preferred shares.

         Dasa's Space Infrastructure Division is industrial prime for the
Columbus Laboratory, the European contribution to the ISS, and its ground
support and operations infrastructure. Besides developing microgravity
facilities and payloads for the Columbus and other ISS Laboratories, Dasa
participates in several other ISS-related projects, including the Automated
Transfer Vehicle, the data management system for the Russian module of the ISS,
the European Robotic Arm, and Crew Transport Vehicles.

         SPACEHAB is the first company to commercially develop, own and operate
habitable modules that provide laboratory facilities and cargo re-supply aboard
NASA's Space Shuttle fleet. With its Johnson Engineering and Astrotech
subsidiaries, SPACEHAB is the world's leading provider of commercial payload
processing services for manned and unmanned payloads. The Company also supports
NASA astronaut training at Johnson Space Center, Houston.

         This release contains forward-looking statements that are subject to
certain risks and
<PAGE>   2
uncertainties that could cause actual results to differ materially from those
projected in such statements. Such risks and uncertainties include, but are not
limited to, whether the Company will fully realize the economic benefits under
its NASA and other customer contracts, the successful development and
commercialization of new space assets, technological difficulties, product
demand, timing of new contracts and business, market acceptance risks, the
effect of economic conditions, uncertainty in government funding, the impact of
competition, and other risks detailed in the Company's Securities and Exchange
Commission filings.
