Item 2.  Acquisition or Disposition of Assets

      On July 1, 1998,  pursuant to a Stock Purchase  Agreement dated as of July
1,  1998  (the  "Stock  Purchase   Agreement"),   Spacehab,   Incorporated  (the
"Registrant"),  acquired all the outstanding  shares of capital stock of Johnson
Engineering Corporation, a Colorado corporation ("Johnson Engineering"). Johnson
Engineering,  headquartered  in  Houston,  Texas,  is  primarily  engaged in the
business of providing engineering services to the National Aeronautics and Space
Administration  ("NASA").  A copy  of the  Stock  Purchase  Agreement  is  filed
herewith as Exhibit 2.1 and reference is made thereto for the complete terms and
conditions thereof.

      The purchase price of $24,500,000 in cash (subject to adjustment following
a review of the closing date  balance  sheet of Johnson  Engineering)  was based
upon the business  prospects of Johnson  Engineering  and the estimated value of
synergies to be realized by the  integration of the Registrant and capital stock
of Johnson  Engineering.  Registrant  purchased  all the  outstanding  shares of
capital stock of Johnson  Engineering  from the former  shareholders,  Eugene A.
Cernan,  William A. Jackson and W.T. Short, all of whom have executed employment
and  non-competition  agreements with Registrant as of July 1, 1998.  Registrant
obtained  the funds for the  purchase  price from an offering in October 1997 of
its 8% Convertible Subordinated Notes due 2007.

      Registrant  intends to operate Johnson  Engineering under its current name
as  a  wholly-owned   subsidiary  of  Registrant.   Registrant  expects  Johnson
Engineering to continue to operate its business in the same manner as before the
acquisition.

                      UNAUDITED PRO FORMA FINANCIAL DATA


      The  following  unaudited  consolidated  pro forma  financial  information
consists of an Unaudited  Pro Forma  Consolidated  Balance Sheet as of March 31,
1998 and  Unaudited  Pro Forma  Consolidated  Statements  of Income for the nine
months  ended  March 31,  1998 and the year ended June 30,  1997 (the "Pro Forma
Statements").

      The  Unaudited  Pro Forma  Consolidated  Balance Sheet gives effect to the
acquisition  of Johnson  Engineering  as if it occurred on March 31,  1998.  The
Unaudited Pro Forma Consolidated  Statements of Income for the nine months ended
March 31, 1998 and the year ended June 30,  1997 give effect to the  acquisition
of Johnson Engineering as if it occurred at the beginning of such periods.

      The  acquisition  of Johnson  Engineering  will be accounted for using the
purchase  method of  accounting  and,  accordingly,  the purchase  price will be
allocated  to the  tangible  and  identifiable  intangible  assets  acquired and
liabilities  assumed  based on their  respective  fair  values as of the date of
consummation  of the  acquisition.  The pro forma  adjustments  are  based  upon
available  information and upon certain assumptions that management believes are
reasonable.  The actual  allocation  of the  purchase  price,  however,  and the
resulting  effect on net income  from  operations  may differ from the pro forma
amounts included herein.

      Management  believes  that, on the basis set forth  herein,  the Pro Forma
Statements reflect a reasonable  estimate of this transaction based on currently
available information.  The pro forma financial data do not purport to represent
what the Company's  financial  position or results of operations  would actually
have been had this  transaction in fact occurred on the date or at the beginning
of the period  indicated  or to project  the  Company's  financial  position  or
results of  operations  for any future date or period  indicated.  The Pro Forma
Statements  should  be read  in  conjunction  with  the  consolidated  financial
statements  and related  footnotes  of  Spacehab,  Incorporated  included in the
Company's 1997 annual report on Form 10-K and the Company's  quarterly report on
Form 10-Q for the quarter ended March 31, 1998.

        Notes to Unaudited Pro Forma Consolidated Financial Statements

      The  Unaudited  Pro Forma  Consolidated  Balance Sheet gives effect to the
acquisition  of Johnson  Engineering  as if it occurred on March 31,  1998.  The
Unaudited Pro Forma Consolidated  Statements of Income for the nine months ended
March 31, 1998 and the year ended June 30,  1997 give effect to the  acquisition
of Johnson Engineering as if it occurred at the beginning of such periods.

(1)   To recognize the acquisition of Johnson Engineering. The Company purchased
      all of the  outstanding  common  stock  from the  former  shareholders  of
      Johnson  Engineering  for $24.5  million in cash  (subject  to  adjustment
      following  a  review  of  the  closing  date  balance   sheet  of  Johnson
      Engineering),  and incurred approximately $1.5 million in costs associated
      with the acquisition.

      The  acquisition  of Johnson  Engineering  will be accounted for using the
      purchase method of accounting and, accordingly, the purchase price will be
      allocated to the tangible and identifiable  intangible assets acquired and
      liabilities  assumed based on their  respective  fair values as of date of
      consummation   of  the   acquisition.   For  purposes  of  the  pro  forma
      information, management of the Company has assumed that the fair values of
      the assets and liabilities acquired will be equal to their respective book
      values  as of the  date  of the  acquisition,  although  the  Company  has
      included a pro forma  adjustment  to record a $1.1  million  liability  to
      recognize the fair value of Johnson Engineering's  long-term contract with
      NASA.

      The pro forma  adjustments  are based upon available  information and upon
      certain  assumptions that management  believes are reasonable.  The actual
      allocation of the purchase price, however, and the resulting effect on net
      income  from  operations  may differ from the pro forma  amounts  included
      herein.

(2)   To reflect the  historical  results of operations of Johnson  Engineering.
      Johnson Engineering had adopted a December 31 year-end,  while the Company
      operates  on  a  June  30  year-end.  Accordingly,  Johnson  Engineering's
      historical  results of  operations  have been  conformed to the  Company's
      fiscal  year-end  of June 30  with  respect  to the  Unaudited  Pro  Forma
      Consolidated Statements of Income for the nine months ended March 31, 1998
      and the year ended June 30, 1997.

(3) To recognize the amortization of goodwill over a 25-year period.

(4)   To recognize the reduction in the  historical  executive  compensation  of
      Johnson Engineering based on employment agreements with certain executives
      of Johnson Engineering.

(5)   To recognize  Federal and state income  taxes.  Prior to the  acquisition,
      Johnson Engineering had elected S Corporation status for federal and state
      income tax purposes,  and accordingly,  Johnson  Engineering's  historical
      results of operations  reflect no provisions for income taxes.  Subsequent
      to the acquisition,  Johnson  Engineering's  results of operations will be
      consolidated  with those of the Company  for federal and state  income tax
      purposes.

(6)   Excludes  an  extraordinary  gain of $3,274 (or $0.29 per  share),  net of
      taxes, relating to the Company favorably amending and restating the Credit
      Agreement.

                       Johnson Engineering Corporation

                        NOTES TO FINANCIAL STATEMENTS

                              December 31, 1997


NOTE A - NATURE OF OPERATIONS AND SUMMARY OF ACCOUNTING POLICIES

Johnson Engineering Corporation (the "Company") was incorporated in the state of
Colorado in 1973 and is primarily engaged in providing  engineering services and
products to the federal government.

On September 1, 1997, the Company sold its technical  staffing services division
for approximately  $421,000,  resulting in a gain of $275,000.  The sale of this
division  had no  significant  impact on the  financial  position  or results of
operations of the Company.

A summary of the significant  accounting  policies  consistently  applied in the
preparation of the accompanying financial statements follows.

 1.   Contract Revenues

In April  1993,  the  Company  was  awarded a  contract  with  NASA  (the  "NASA
Contract")  for a period of five years,  with priced option  renewals up to nine
years. The Company derived  approximately 97% of its total revenues for the year
ended  December  31,  1997 from  this  long-term  federal  contract  with  NASA.
Additionally,  at December 31, 1997, approximately 97% of the Company's accounts
receivable  were due from NASA. In April 1998,  NASA exercised the first renewal
option, which extended the contract to April 2001.

The Company's NASA contract is on a cost-plus-award-fee  basis and is subject to
review  and  negotiation  by  NASA.  Revenues  on  cost-plus-fee  contracts  are
recognized  to the extent of costs  incurred plus  base-fee  revenues  using the
percentage-of-completion  method, measured on costs incurred.  Award fees, which
provide  earnings based on the Company's  contract  performance as determined by
periodic  NASA  evaluations,  are  recorded  when the amounts can be  reasonably
estimated, or are awarded. As award fees are determined by NASA evaluations,  it
is at least reasonably possible estimated award fees will be revised in the near
term.  Approximately  $400,000 of estimated  award fees  recognized as income in
1997 are subject to  evaluation.  Retainages  of  $147,800 at December  31, 1997
represent  amounts  withheld on contracts  until NASA  performs  final  contract
audits.

Contract costs, including indirect costs, are subject to audit and adjustment by
negotiations  between the Company and NASA. The Company has reserved $130,958 as
accrued contract liability for potential  disallowed costs and future credits on
government contracts as of December 31, 1997.

Unbilled revenues  represent amounts earned but not yet billed by the Company on
contracts.

NOTE A - NATURE OF OPERATIONS AND SUMMARY OF ACCOUNTING POLICIES - CONTINUED

 2.   Property and Equipment

Property and equipment are recorded at cost.  Depreciation  and amortization are
provided using  straight-line and accelerated  methods over the estimated useful
lives of the related assets ranging from three to seven years.

Depreciation  expense of $94,412 was  recorded  for the year ended  December 31,
1997.

 3.   Income Taxes

Federal income taxes on net earnings are payable  personally by the stockholders
pursuant to an election under  Subchapter S of the Internal  Revenue Code not to
have the Company taxed as a corporation. Accordingly, no provision has been made
for federal income taxes.

 4.   Use of Estimates

The preparation of financial  statements in conformity  with generally  accepted
accounting principles requires management to make estimates and assumptions that
affect the amounts reported in the financial  statements and accompanying notes;
accordingly, actual results could differ from those estimates.

NOTE B - COMMON STOCK TRANSACTIONS

The Company issued 20,000 shares of common stock for a $700,000 note  receivable
from  stockholders in 1994. The 6.34%  interest-bearing  note receivable for the
stock  subscription  which was  collateralized by the common stock purchased and
had been reflected as a component of  stockholders'  equity in the  accompanying
financial statements was distributed to the stockholders in 1997.

NOTE C - NOTE PAYABLE TO BANK

The Company has a $2,500,000 line of credit agreement which is collateralized by
cash, accounts receivable,  inventory,  and equipment.  The line of credit bears
interest at the bank's base rate plus .5% (9% at December 31, 1997) and contains
restrictive covenants relating to tangible net worth, ratio of current assets to
current  liabilities,  coverage of earnings  before  interest,  income taxes and
depreciation  and  amortization to outstanding  debt,  dividends and payments to
stockholders,  among other  restrictions.  The line of credit matures on May 31,
1998, and at December 31, 1997, no amounts were outstanding under the line.

NOTE D - COMMITMENTS

The Company has a consulting  contract with the Company's  former president that
provides  for a retainer as well as a percentage  of contract  net  profits,  as
defined,  for contract years six through nine (currently in contract year five);
new contracts net profits,  as defined,  obtained before  September 1, 1998; and
net revenue on shelf technology that existed at November 1994.

The Company rents office space and equipment  under  operating  leases.  Related
rent expense was $333,270 for the year ended  December 31, 1997.  Future minimum
lease  commitments  as of December 31, 1997 for the office and equipment  leases
are as follows:

                                                ==========

NOTE E  - EMPLOYEE SAVINGS PLAN

The Company has an employee  savings plan under  Section  401(k) of the Internal

<PAGE>




            (i)   Seventeen    Million   Nine   Hundred    Thousand    Dollars
                  ($17,900,000) payable to Sellers at closing;

            (ii)  Two Million Five Hundred  Thousand Dollars  ($2,500,000)  (the
                  "Blanket  Escrow  Fund")  delivered  to the  Escrow  Agent (as
                  defined in the Escrow Agreement), to be released in accordance
                  with the terms and  provisions  of the  Escrow  Agreement  set
                  forth as Exhibit IV.A hereto;

            (iii) Three  Million  Dollars  ($3,000,000)  (the  "Award Fee Escrow
                  Fund")  delivered  to the  Escrow  Agent,  to be  released  in
                  accordance  with  the  terms  and  provisions  of  the  Escrow

            (iv)  One Million One Hundred  Thousand  Dollars  ($1,100,000)  (the

      The  Purchase  Price  shall be payable  by wire  transfer  of  immediately

Agent shall theretofore designate in writing to Buyer, or by such other means as
are agreed upon by Sellers,  Buyer and Escrow Agent. The Purchase Price shall be
allocated among the Sellers as set forth on Annex I hereto.

      c)    Closing and Post-Closing Adjustment.

            (i)   Definitions.

                  "GAAP" shall mean Generally Accepted Accounting  Principles as
                  historically applied by the Company.

                  "Retained  Earnings"  shall be given the  meaning  ascribed to
                  this concept in accordance with GAAP.

                  "Special  Bonus"  shall mean a one-time  bonus of Five Hundred
                  Thousand Dollars ($500,000) payable by the Company on June 30,
                  1998 and distributed among certain  employees,  such bonus not
                  being  charged  directly or indirectly to any of the contracts
                  to which NASA is signatory and taking into account any payroll
                  or similar taxes and deductions which are normally assessed on
                  such compensation payable.



<PAGE>


            (ii)  Estimated  Closing  Adjustment.  At  Closing,  Sellers  will
                  deliver to Buyer an estimated  award fee income  calculation
                  for the  period  from June 1, 1998 to, and  including,  June
                  30,  1998,  to be attached to this  Agreement as Exhibit VI,
                  such estimate  being  prepared in  accordance  with GAAP and
                  being based on an  estimated  NASA award fee of seventy five
                  percent  (75%)  for such  period  of  operation  (the  "June
                  Income  Estimate").  The  Company  will then pay Sellers the
                  result of the following  calculation:  the Retained Earnings
                  as at May 31, 1998  according to the unaudited  statement of
                  income and Retained  Earnings being  delivered in accordance
                  with  Section  4(e)(iii)  of  this  Agreement  (the  "May 31
                  Income"),  plus the June Income Estimate,  less the Retained
                  Earnings on the  audited  statement  of income and  retained
                  earnings  for the twelve  (12)  months  ended  December  31,
                  1997,  less any  distributions  and less any other  payments
                  outside of the  ordinary and  historical  course of business
                  made by the Company to Sellers after May 31, 1997,  less the
                  Special Bonus.

            (iii) Post-Closing  Adjustment.   Within  fifteen  (15)  days  after
                  receiving  payment  from NASA  relating to the award fee score
                  determinations  for the  Company  for  both  of the  operating
                  periods  ending March 31 and September  30, 1998,  Buyer shall
                  calculate  the  Retained  Earnings as at June 30,  1998,  such
                  calculation  being  prepared  to reflect  the award fee scores
                  granted  by NASA for the  periods  ending  March 31,  1998 and
                  September  30, 1998 and according to the same  methodology  as
                  was used in determining  the May 31 Income (the result of such
                  calculation  being  hereinafter  referred  to as the  "Closing
                  Income"). Buyer shall then make the following calculation: the
                  Closing  Income,  less the payment made to Sellers as a result
                  of the application of Section  1(c)(ii) of this Agreement.  If
                  this amount is a positive  number,  the  Company  shall pay to
                  Sellers  within  30 days  such  amount.  If this  amount  is a
                  negative number, Sellers will have received an over-payment by
                  operation  of Section  1(c)(ii)  of this  Agreement  and shall
                  reimburse the Company for this over-payment within 30 days, it
                  being understood that such amount,  unless otherwise agreed by
                  Buyer, will not be drawn from any fund established as a result
                  of any of the Escrow Agreements attached hereto as Exhibits.

      SECTION 2.  THE CLOSING.



<PAGE>


      a) Time and Place of Closing.  On the terms and subject to the  conditions
contained in this Agreement,  the closing of the purchase and sale of the Shares
(the  "Closing")  shall  take place at the  offices of Porter & Hedges,  L.L.P.,
Houston,  TX, 77002-2764 on July 1, 1998 or at such other place or time as shall
be mutually agreed to by the parties (the "Closing Date").

      b) Delivery and Payment.  At the  Closing,  each Seller shall  deliver (or
cause to be delivered) to Buyer stock  certificates  representing  the number of
Seller's  Shares set forth  opposite such Seller's name on Annex I hereto,  duly
endorsed or  accompanied  by duly executed  stock powers in blank and having all
necessary stock transfer tax stamps affixed thereto at the expense of Sellers in
form suitable for transfer of valid title thereto to Buyer free and clear of any

collectively  the  "Contracts" ) is valid and enforceable in accordance with its
terms and the Company is not, and will not be with notice, the lapse of time, or
both, in material default under any provision of any such contract, agreement or
commitment.  To the Sellers' knowledge,  any Person which is a party to any such
agreement,  contract or  commitment,  is not, and will not be with  notice,  the
lapse of time or both,  in  material  default  under any  provision  of any such
contract, agreement or commitment. To the Seller's knowledge, by concluding this

dealings  with the  Company  nor any  management  employee  of the  Company  has
notified  Sellers or the  Company or any of its  employees,  and no Seller has a
reasonable  basis to believe,  that any such Person or entity (i) has threatened
to terminate,  either for convenience or default, any contract which is material
to the Business,  (ii) might cease its dealings or  employment  with the Company
after the Closing  Date, or (iii) might seek to  re-negotiate  any or all of the
terms of any  contract  or other  arrangement  which  governs  the  relationship
between this party and the Company, any Seller, or Sellers.

      q     Intellectual Property.



<PAGE>


            i     No Person other than the Company has an  ownership  interest
                  in, or a right to receive a royalty or similar  payment with
                  respect  to, any of the  Intellectual  Property  or Computer
                  Software  listed on  Schedule  4(l)(iii)  hereto,  except as
                  noted in such  Schedule.  No  intellectual  property  rights
                  other than the Intellectual  Property, the Computer Software
                  and the  Licenses  are required to permit the conduct of the
                  business  of the Company as now  conducted.  The Company has
                  good title to, or is licensed or otherwise  has the right to
                  use, all of the  Intellectual  Property  listed on Schedule
                  4(l)(iii),  free and clear of any  Encumbrance or royalty or
                  other payment requirements of any nature whatsoever,  except
                  as noted in such Schedule.

            ii    All  Intellectual  Property is valid and  enforceable to the
                  extent of the Company's  ownership therein,  and none of the
                  Intellectual  Property  has been  cancelled  or abandoned or
                  licensed  by the  Company in such a way as could  reasonably
                  be  expected  to have an adverse  effect on the  validity of
                  such  Intellectual  Property or dedicate same to the public.
                  The  Company  is listed in the  records  of the  appropriate
                  U.S.  agency as the sole and  exclusive  owner of record for
                  each registration, grant and application listed in Schedule
                  4(l)(iii)   as  to  which  it  claims  sole  and   exclusive
                  ownership   in   said   schedule.   All   registration   and
                  maintenance  fees  that  have  become  due  and  payable  in
                  respect  of any such grant or  registration  have been paid.
                  To the best of the  Sellers'  knowledge,  the Company is not
                  infringing  upon, or otherwise  violating,  the intellectual
                  property  rights  of  any  third  party.   The  Company  has
                  received  no notice of any  proceedings  or claims  that are
                  infringing upon or otherwise  violating any such rights, and
                  the  Company  and  the  Sellers  are  unaware  of  any  such
                  infringement  or  violation  as to which notice has not been
                  received by the Company.  No  proceedings or claims in which
                  the Company  alleges that any third party is infringing upon
                  or otherwise violating any of the Intellectual  Property are
                  pending  and  none  have  been  served  by,   instituted  or
                  asserted by the Company.  Without  limiting  the  generality
                  of the foregoing, no trademark,  service mark, trade name or
                  corporate  name used by the  Company,  infringes  or dilutes
                  the  trademark,  service mark,  corporate name or trade name
                  of any person.

                  infringe  the  rights  of any  third  party.  Except  as set
                  forth on Schedule  4(l)(iii),  the Company has obtained from
                  all  individuals  who  participated  in any  respect  in the

                  rights of such  individuals in such Computer  Software,  and

                  thereto,  other than from such  individuals  whose works the
                  Company  hereby  represents  to be  "works  made  for  hire"

                  covered by such annual  report  since the date  thereof.  No
                  actual or threatened disputes,  lawsuits, claims (other than
                  routine  claims  for  benefits)  investigations,  audits  or
                  complaints  to, or by,  any  person or  governmental  entity
                  have been filed or are pending with respect to the Plans.

            iv    None of the assets of the Plans is  invested  in any  property
                  constituting  employer real  property or an employer  security
                  within the meaning of Section 407(d) of ERISA.

            v     The  Company  (or  any  entity  that  is or was at any  time

                  414(b),  (c),  (m) or (o) of the  Code)  has not at any time
                  (x)   maintained,   contributed   to  or  been  required  to
                  contribute  to any plan under  which more than one  employer
                  makes  contributions  (within the meaning of Section 4064(a)
                  of  ERISA)  or any plan that is a  Multiemployer  Plan,  (y)
                  incurred  or expects to incur any  liability  to the Pension
                  Benefit Guaranty  Corporation or otherwise under Title IV of
                  ERISA (other than the payment of premiums  none of which are
                  overdue) or (z)  incurred or expects to incur  liability  in
                  connection with an "accumulated  funding  deficiency" within
                  the  meaning  of  Section  412 of the  Code  whether  or not
                  waived.

            vi    Each Plan that is intended to qualify under  Section  401(a)
                  of the Code is qualified  under Section  401(a) of the Code,
                  and to the knowledge of the Company,  there is no reason why
                  such   tax-qualified   status   should   be   revoked.   All
                  contributions  due with respect to the periods  ending on or
                  before the  Closing  Date to the Plans have been timely made
                  and a pro  rata  portion  of  the  contributions  (including
                  matching  contributions)  for the current plan year has been
                  made  or  appropriate  charges  will  be  reflected  on  the
                  Balance Sheet.

            vii   Neither  the  Company  nor any  other  person,  including  any
                  fiduciary,  has engaged in any  "prohibited  transaction"  (as
                  defined in Section  4975 of the Code or Section 406 of ERISA),
                  which could  subject any of the Plans (or their  trusts),  the
                  Company,  or any person who the Company has an  obligation  to
                  indemnify, to any tax or penalty imposed under Section 4975 of
                  the Code or Section 502 of ERISA.

                  modify at any time each of the Plans.

                  the foregoing.

            ii    The  Company  has  timely   filed  all   reports,   returns,

                  to such  Returns  have  been  paid or will be paid when due.
                  No  adjustment  relating to such  Returns has been  proposed
                  formally or informally by any taxing  authority  and, to the
                  knowledge  of the Company and the  Sellers,  no basis exists
                  for any such adjustment.

                  Return  filed  by  the  Company  for  which  the  applicable

                  all  jurisdictions  in which the Company has filed an income
                  or  franchise  Tax Return.  Except as set forth in Schedule

                  from the  Company)  for any past due Taxes;  the Company has
                  not waived any  statute of  limitations  in respect of Taxes

                  entered  into  by or  with  respect  to the  Company  or the
                  Sellers.

            viii  There are no liens or  Encumbrances  upon the Common  Stock or
                  upon any asset of the Company  that arose in  connection  with
                  any  failure (or  alleged  failure) to pay any Tax.  Except as
                  provided on  Schedule  4(l)(x),  no power of attorney  that is
                  currently in force has been granted to any person with respect

                  period or portion thereof ending on or before the date hereof.

                  related to the Buyer within the meaning of such aforementioned
                  Sections of the Code.

      z No Brokers.  Neither  Sellers nor the Company have entered into and will
not enter into any agreement, arrangement or understanding with any Person which
may  result  in an  obligation  of  Buyer  to pay any  finder's  fee,  brokerage
commission or similar payment in connection with the  transactions  contemplated
hereby.

      aa Illegal  Payments.  Neither the Company nor any Company  Personnel  has
made any payment of funds of the Company  prohibited by law, and no funds of the
Company have been set aside to be used for any payment prohibited by law.

      bb  Transactions  with  Certain  Persons.  Except as disclosed on Schedule

any  Family  Member  or any  Affiliate  thereof  is  presently  a  party  to any
transaction with the Company relating to the business of the Company, including,
without limitation,  any contract,  agreement or other arrangement (i) providing
for the  furnishing  of services  by, (ii)  providing  for the rental of real or
personal  property from, or (iii)  otherwise  requiring  payments to (other than

will constitute, all of the assets and services that are necessary to permit the
business of the Company to be conducted by Buyer in substantially  the manner as
it has  heretofore  been  conducted  and  none of the  Sellers  or any  officer,
director  or  employee  of the  Company  or any Family  Member or any  Affiliate
thereof or any other Person owns any of such assets.

      dd Exclusive  Use of Bank  Accounts.  The bank  accounts and  safe-deposit

Company  have  discharged  all  obligations  and  liabilities  relating  to such

effect filings under the  Hart-Scott-Rodino  Antitrust  Improvements Act of 1976
(the "Hart-Scott-Rodino Act") arises as a result of this Agreement, Buyer relied
on  Sellers'  and  the  Company's  representations  that  (i) the  value  of the
Company's  assets as  determined  under the  Hart-Scott-Rodino  Act and  related
regulations  does not exceed $10  Million  dollars and (ii) the Company is not a

dealings  with the  Company  nor any  management  employee  of the  Company  has
notified  Sellers  or the  Company,  and no  Seller  has a  reasonable  basis to
believe,  that any such person or entity would or might cease business  dealings
or  employment  with the Company after the Closing Date. No customer or supplier
which was material to the business of the Company in the past twelve  months has
terminated in writing or materially  reduced its purchases  from or provision of

Non-competition Period, engage or participate in directly or indirectly (whether
as an officer, director, employee, partner,  consultant,  holder of an equity or
debt investment,  lender or in any other manner or capacity),  or lend it or his
name (or any part or variant  thereof) to, any business which is, or as a result
of Sellers' engagement or participation would become competitive with any aspect
of the  business  of the  Company;  (ii)  deal,  directly  or  indirectly,  in a
competitive manner with any customers doing business with the Company during the

of debt  securities of any  corporation  with one or more classes of its capital
stock  listed  on a  national  securities  exchange  or  actively  traded in the
over-the-counter market shall not, in and of itself,  constitute a breach of the
foregoing  covenant.  Each Seller is  entering  into the  foregoing  covenant to
assure Buyer of the  transfer of the  goodwill of the  Company,  and in order to
induce Buyer to consummate the purchase contemplated by this Agreement.

      b Release.  Except for the enforcement of the terms and provisions of this
Agreement  and for any  agreements  to be  entered  into  by the  Company  at or
following  the  Closing,  Sellers  hereby and on behalf of all  Family  Members,

and agree to hold  harmless the Company  following  the Closing from any and all
claims that they may have or be able to allege.

      c Non-disclosure.  Each Seller will not at any time after the date of this
Agreement  divulge,  furnish to or make  accessible  to anyone any  knowledge or
information  with  respect  to  confidential  or secret  processes,  inventions,
discoveries,  improvements,  formulae,  plans,  material,  devices  or  ideas or
know-how,  whether patentable or not, with respect to any confidential or secret
aspects of the Business of the Company (including, without limitation,  customer
lists,  supplier  lists and pricing  arrangements  with customers or suppliers);
provided, however, that nothing herein shall prohibit each Seller or the Company
from complying  with any order or decree of any court of competent  jurisdiction
or governmental authority,  but each Seller will give Buyer timely notice of the
receipt of any such order or decree.

      d Access to  Facilities;  Due  Diligence.  Between the date hereof and the
Closing Date:  (i)  authorized  representatives  of Buyer shall have  reasonable
access to all  properties,  books,  Records,  Contracts  and other  documents of

Company will furnish to Buyer all information  with respect to the Business that
Buyer reasonably requests.

      e Further Assurances.  To the best of their abilities, for a period of two
(2) years after the Closing  Date Sellers  will,  and will cause the Company and
all Company  Personnel to,  cooperate  fully with Buyer in  connection  with the
transactions contemplated by this Agreement.  Without limiting the generality of
the foregoing, for a period of two (2) years from and after the Closing Date and
with respect to those representations and warranties related to Sections 9(a)(i)
and  9(a)(ii)  of this  Agreement,  from time to time,  at Buyer's  request  and
without further consideration,  Sellers will execute and deliver, or cause to be
executed and  delivered,  such other  instruments  and take such other action as
Buyer  may  reasonably  request  in  order  to carry  out the  purposes  of this
Agreement;  provided,  that Sellers shall not be required to make any payment to
any third  party other than its  employees  and  representatives  (such as legal
counsel and accountants) in complying with this covenant.

      f Filing of Tax Returns and Payment of the Tax.

            i     The Company  shall  timely file or cause to be timely  filed
                  all  Tax  Returns  that  are  required  to  be  filed  (with
                  extensions)  on or before  the  Closing  Date.  The  Company
                  shall  timely  pay  or  cause  to be  timely  paid  all  Tax
                  reported,  or required to be reported,  on such Returns. The
                  Sellers are liable for and have paid,  or (to the extent not
                  yet due and  payable)  will pay,  in a timely  fashion,  all
                  Taxes required to be paid  attributable  to their  ownership
                  of the Company stock in respect of all periods  ending on or
                  prior to the Closing Date,  including,  without  limitation,
                  Taxes for which  they are  liable  due to the  status of the
                  Company as an S Corporation  for federal income tax purposes
                  (and any  analogous  provisions  of state or local law).  To
                  the extent not  covered by the  Deduction  Escrow and by the
                  provisions   of  this   Agreement  as  they  relate  to  the
                  Deduction  Escrow Fund, the Sellers  further shall be liable
                  for, and, at the direction of the Buyer,  shall pay directly
                  the  applicable  taxing  authority on or before the due date
                  therefor  or,  within  ten (10) days of any  payment  by the
                  Buyer or the  Company in respect  thereof,  shall  reimburse
                  the  Buyer  for  the   payment   of,  any  and  all  finally
                  adjudicated  Taxes  of  the  Company   attributable  to  any
                  taxable  period  ending on or prior to the Closing  Date and
                  the  allocable  portion of any and all Taxes of the  Company
                  attributable  to any partial  period  (through and including
                  the Closing  Date) of any taxable  period  beginning  before
                  and ending  after the  Closing  Date to the extent that such
                  Taxes are not  reflected  in the  reserve for Taxes shown in
                  the  Closing  Documents.   The  Taxes  attributable  to  any
                  partial  period shall be computed in the manner set forth in
                  Section 6(g).  At the Closing,  the Sellers shall deliver to
                  the  Buyer a  schedule  that  lists all Tax  Returns  of the
                  Company  for all  taxable  periods  ending on or before  the
                  Closing Date that are not  required to be filed  pursuant to
                  Section 4(y).

            ii    After the Closing  Date,  the Buyer shall  prepare and file,
                  or shall  cause to be  prepared  and filed,  all Tax Returns
                  for the Company  for all  periods  ending on or prior to the
                  Closing  Date which are filed  after the Closing  Date.  The
                  Buyer  shall  permit the  Sellers  to review and  comment on
                  each such Tax Return  described  in the  preceding  sentence
                  prior  to  filing,  and  such  Returns  shall  not be  filed
                  without Sellers' prior written consent,  such consent not to
                  be  unreasonably   withheld.  To  the  extent  permitted  by
                  applicable law, the Sellers shall include any income,  gain,
                  deduction  or other tax items for such  periods of their Tax
                  Returns  in a  manner  consistent  with  the  Schedule  K-1s
                  furnished by the Company to the Sellers for such period.

            iii   Sellers,  the Buyer and the Company shall  cooperate  fully,
                  as and to  the  extent  reasonably  requested  by the  other
                  party,   in  connection  with  the  filing  of  Tax  Returns
                  pursuant to this Section and any audit,  litigation or other
                  proceeding  with respect to Taxes.  Such  cooperation  shall
                  include the retention  and (upon the other party's  request)
                  the   provision  of  records  and   information   which  are
                  reasonably   relevant  to  any  such  Tax   Return,   audit,
                  litigation or other proceeding.

            iv)   All Tax Returns  described in this Agreement shall be prepared
                  in a manner consistent with past practice,  except for changes
                  in applicable law with the consent of the Buyer.

            v)    At the Buyer's option,  the Company and each of the Sellers,
                  including  consenting  spouses,  will join with the Buyer in
                  making the Section  338(h)(10)  Election.  The Sellers  will
                  include any income,  gain, loss, deduction or other tax item
                  resulting from the Section 338(h)(10)  Election on their Tax
                  Returns to the extent  permitted  or required by  applicable
                  law.  For  purposes  of  clarification,  it is  specifically
                  agreed  that Buyer shall  reimburse  Seller for any tax cost
                  arising   from   Buyer's   decision   to  effect  a  Section
                  338(h)(10) Election.

            vi)   Subject to  subparagraph  (vii) below,  any refunds of Taxes
                  not reflected as a receivable  on the Closing  Balance Sheet
                  that  are  received  by the  Buyer or the  Company,  and any
                  amounts  credited  against Tax not  reflected on the Closing
                  Balance  Sheet to which  the  Buyer or the  Company  becomes
                  entitled,  that  relate to the  taxable  periods or portions
                  thereof  ending on or prior to the  Closing  Date,  shall be
                  for the  account of the  Sellers  and the Buyer shall pay to
                  the  Sellers  any  such  refund  or the  amount  of any such
                  credit within  fifteen (15) days after receipt  thereof.  In
                  addition,  to  the  extent  that a  claim  for  refund  or a
                  proceeding  results in a payment or credit  against Tax by a
                  taxing  authority  to the Buyer or the Company of any amount
                  reflected  in the  reserve  for Taxes  shown on the  Closing
                  Balance  Sheet,  the  Buyer  shall  pay such  amount  to the
                  Sellers  within  fifteen  (15) days after  receipt  thereof.
                  Any amount due to the Sellers under this paragraph  shall be
                  subject to offset  for any  amounts  owed by the  Sellers to
                  the  Buyer  under  this  paragraph.  Any  refunds  of  Taxes
                  reflected  as a  receivable  on the  Closing  Balance  Sheet
                  which are  received by the Sellers  shall be for the account
                  of the  Buyer  and the  Sellers  shall  pay to the Buyer any
                  such refund or the amount of any credit within  fifteen (15)
                  days after  receipt or  entitlement  thereto.  In  addition,
                  the  Sellers  shall  pay  to the  Buyer  the  amount  of any
                  refunds  of  Taxes  or  amounts   credited   against   Taxes
                  reflected as a receivable  on the Closing  Balance Sheet not
                  in fact received by the Buyer.

            vii)  If the  Company's  taxable  income  is  adjusted  due to the
                  filing  of  an  amended  return,   adjustment  by  a  Taxing
                  authority,  or  otherwise,  and such  change  results  in an
                  increase in income in a  pre-Closing S return Tax year and a
                  related and opposite  change in a  post-Closing  Tax period,
                  the  Company  and the Buyer shall pay to the Sellers all tax
                  benefit  expected  to  be  generated  from  such  offsetting
                  reductions  in  income  in  all  post-Closing  Tax  periods,
                  computed at the highest  federal,  state and local corporate
                  tax rate (with  state and local tax rates  adjusted  for the
                  benefit of the federal tax deduction).

                  If the Company's  taxable income is adjusted due to the filing
                  of an amended  return,  adjustment by a Taxing  Authority,  or
                  otherwise,  and such change results in a decrease in income in
                  a  pre-Closing  S return  Tax year and  opposite  change  in a
                  post-Closing  Tax period,  the Sellers  shall pay to the Buyer
                  all tax benefit  expected to be generated from such offsetting
                  reductions in income in all pre-Closing Tax periods,  computed
                  at the highest  marginal  federal,  state and local individual
                  tax rate for each such Seller.



<PAGE>


                  For example,  if an amount  expensed in a pre-Closing S return
                  Tax  period  is  capitalized  by a Taxing  authority  (and the
                  Sellers consent to such adjustment),  which capitalized amount
                  is depreciable in post-Closing  Tax periods,  the Sellers will
                  pay  the  additional  Tax  on  their  increased   allocable  S
                  corporation  income,  and the  Company  and Buyer will pay the
                  Sellers  the  tax  benefit   realized  from  their   increased
                  post-Closing tax depreciation.  Any payment arising under this
                  Section  6(f)(vii)  will be paid  within 90 days of receipt of
                  the  final  agreed   adjustment  from  the  taxing  authority,
                  computed by taking the corresponding tax benefit at a discount
                  rate of 15%.

      g)  Apportionment   regarding  Taxes.  Except  as  otherwise  required  by
applicable  law, for any taxable  period that begins on or before and ends after
the Closing  Date,  for  purposes of  apportioning  a Tax to the portion of such
taxable  period that ends on the Closing  Date,  (i) the parties shall treat the
Closing  Date as the last day of such  taxable  period  and (ii) the Tax for the
taxable  period that is allocable to the portion of the taxable period ending on
the  Closing  Date shall (A) in the case of a Tax that is not based on income or
gross  receipts,  be deemed to be the amount of such Tax for the entire  taxable
period multiplied by a fraction, the numerator of which is the number of days in
the  taxable  period  ending  on  (and  including)  the  Closing  Date  and  the
denominator of which is the total number of days in the entire  taxable  period,
and  (B) in the  case of any Tax  based  upon or  related  to  income  or  gross
receipts,  be deemed  equal to the amount that would be payable if the  relevant
taxable  period ended on the Closing  Date,  based on actual  operations  of the
Company  during such period as shown on its  permanent  books and  records.  All
determinations  necessary to give effect to the foregoing  allocations  shall be
made in a manner consistent with prior practice of the Company.

      h) Access to Information  regarding Taxes. From the date hereof, the Buyer
shall,  and cause the  Company  to,  make  available  to the  Sellers  and their
representatives,  and the Sellers shall cause to be made  available to the Buyer
and the Company and their representatives: (i) all Tax Returns and all documents
and records in  connection  with the  preparation  thereof  for taxable  periods
ending on or before the Closing Date and any examination  reports and statements
of deficiencies assessed against,  proposed to be assessed against, or agreed to
by the Company for such taxable periods;  and (ii) any Tax sharing or allocation
agreement or  arrangement  involving the Company at any time during the ten-year
period ending on the date hereof and a true and complete description of any such
unwritten or informal agreement or arrangement.

      i) Books and  Records.  The Buyer  shall  retain or cause the  Company  to
retain all books and records pertinent to the Company for each taxable period or
portion  thereof  ending on or prior to the Closing Date until the expiration of
the applicable  statute of limitations  (giving effect to any and all extensions
and  waivers)  and to abide by or cause  compliance  with all  record  retention
agreements  entered  into  by or on  behalf  of  the  Company  with  any  taxing
authority.



<PAGE>


      j) Notice of Audit.  If the Buyer  receives  any  written  notice from any
taxing authority proposing an adjustment to any Tax for which the Sellers may be
personally  liable or be obligated to indemnify the Buyer under this  Agreement,
the Buyer shall give prompt written notice thereof to the Sellers that describes
such proposed  adjustment in reasonable  detail  ("Notice of Audit"),  and shall
indicate  the  amount  (estimated,  if  necessary)  of the Tax and  other  items
described  in this  Agreement  that may be suffered by the Buyer or the Company.
The failure to give a Notice of Audit  pursuant to this Section  6(j),  however,
shall not reduce the  obligations of the Sellers  hereunder  unless,  and to the
extent that,  such failure  prejudices the rights of the Sellers to contest such
Tax.

      k) Tax Contest.  The Buyer and its duly  appointed  representatives  shall
have the sole right to defend,  negotiate,  resolve, settle or contest any claim
for Tax made by a taxing  authority  with  respect  to any  period  in which the
Company was a "C"  corporation and the Sellers shall have the same rights during
any period in which the Company was a Subchapter S corporation, in each case for
periods prior to the Closing Date and for which the Sellers have indemnified the
Buyer under this Agreement;  provided, however, that Buyer shall not be required
to contest any claim unless (A) it has received  from the Sellers,  in such form
as Buyer shall deem satisfactory,  indemnification  and security for any and all
actual  or  anticipated  liability,  loss,  cost or  expense  arising  out of or
relating to such amount or the contest thereof,  including,  but not limited to,
all  attorneys'  and  accountants'  fees and expenses,  penalties,  interest and
additions  to tax, (B) if the contest  shall be conducted in a manner  requiring
the  payment  of all or part of such  amount,  the  Sellers  shall have paid the
amount  required,  and (C) the Sellers shall have  acknowledged in writing their
liability  to indemnify  Buyer fully for the  contested  Tax and any  additional
interest,  penalties, or expenses arising as a result of such contest; provided,
however,  that,  if the  Sellers  have  complied  with the  foregoing  and Buyer
declines  to  contest  such  Tax  claim,  the  Buyer  will  waive  its  right to
indemnification.  Buyer shall not settle any Tax contest or  otherwise  take any
action  that could  adversely  affect the  Sellers,  without  the consent of the
Sellers, which consent shall not be unreasonably withheld.

      l) Transfer  Taxes.  The Sellers  shall bear the cost of any  documentary,
stamp, transfer, or similar transfer tax payable with respect to the transfer of
the Common Stock to the Buyer.

      m) Collection of Receivables.  After the Closing Date, all cash, checks or
other  proceeds  received  by  Sellers  or any of its  banks or other  financial
institutions that relate to the accounts receivable of the Company shall be paid
to the Company  within ten (10) business  days after  receipt by Sellers,  which
payments shall be accompanied by a statement  identifying the payee,  the amount
of the payment and the related invoice  number.  Sellers shall give Buyer access
to any and all lockboxes of the Company where  payments for accounts  receivable
are remitted,  if any.  Sellers  shall  instruct its banks to remit to Buyer all
amounts  received by such banks with respect to such accounts.  Sellers agree to
endorse  and Buyer  shall have the right to  endorse  the name of Sellers on any
such checks or proceeds  (whether  received  directly by Buyer or received  from
Sellers or its bank) and shall  deposit  such checks and other  proceeds in bank
accounts  maintained  in the  Company's  name.  From and after the Closing Date,
Sellers shall  cooperate  with, and provide  reasonable  assistance to, Buyer in
collecting such accounts.



<PAGE>


      n) Assignment of Receivables.  If any Account Receivable of the Company is
not  collected  by the Company  within  sixty (60) days after the Closing  Date,
Buyer may, at its option, cause the Company to assign such Account Receivable to
Sellers and Sellers shall pay Buyer  directly or through the Escrow an amount in
cash equal to the account  receivable so assigned within three (3) business days
after assignment by Buyer.

      o) Capital Expenditures. From the date of this Agreement until the Closing
Date, neither Sellers nor the Company will incur any capital  expenditure or any
liability  therefor  requiring  any  payment  or  payments  in excess of $10,000
individually  or $250,000 in the aggregate  without the prior written consent of
Buyer.

      p) Government  Clearances.  As soon as practicable  following execution of
this Agreement,  Sellers shall prepare and provide to Buyer,  which shall be set
forth in Schedule 6(s), a description of all existing government clearances (the
"Government Clearances") issued to Sellers or its Personnel under, in connection
with,  or relating to the  Company's  Contracts or Business,  including  but not
limited to all  facilities  clearances  and personnel  clearances in the name of
Sellers.  Sellers shall provide to Buyer promptly any  information  requested by
Buyer  relating to or involving  the  information  described  on Schedule  6(s).
Sellers  shall  promptly  provide such  cooperation  and  assistance,  and shall
execute such documents and consents as Buyer shall reasonably request, to assist
in the transfer or  assignment of the  clearances  described on Schedule 6(s) to
the Company and/or the application for issuance of new clearances to the Company
in connection  with this Agreement as may be required or requested by applicable
governmental  authorities  or may be needed to operate the Business as currently
operated.

      q)  Blanket   Escrow  Fund.  In  the  event  that  Buyer  is  entitled  to
indemnification  as a result of Section 9(c) of this  Agreement,  Buyer shall be
entitled to reimbursement out of the Blanket Escrow Fund which is established as
a result of this Agreement and of the Escrow Agreement  attached as Exhibit IV.A
hereto.

      r) Award Fee Escrow  Fund.  The Award Fee Escrow Fund applies to the award
fee  determinations  which will be granted by NASA for the  following  operating
periods:  (a) April 1, 1998 to September 30, 1998;  (b) October 1, 1998 to March
31, 1999;  (c) April 1, 1999 to September 30, 1999; (d) October 1, 1999 to March
31,  2000;  and (e) April 1, 2000 to  September  30,  2000.  Upon receipt by the
Company  of NASA's  payment of the award fee for each of these  periods,  if the
award fee score is 85 or higher, Seller will be entitled to withdraw Six Hundred
Thousand  Dollars  ($600,000)  from the Award Fee Escrow Fund, and, if the award
fee score is 84 or lower,  Buyer will be entitled  to  withdraw  the same amount
from the Award Fee Escrow Fund, all as provided in the Escrow Agreement attached
as Exhibit IV.B hereto.



<PAGE>


      s) Deduction  Escrow Fund.  If any Tax Return filed by the Company for any
period  ending  before the Sellers'  election to be treated as an S  Corporation
became  effective  (as of April 1,  1996) is  challenged  or  reassessed  by the
Internal  Revenue  Service or by any similar  taxing  authority  on the basis of
deductions  taken in connection  with employees or  consultants,  Buyer shall be
entitled to be reimbursed  for any cost resulting  from such  reassessment.  Any
reimbursement  which results from the  application of this Section 6(s) shall be
drawn from the Deduction Escrow Fund, in accordance with this Agreement and with
the Escrow Agreement  attached as Exhibit IV.C hereto. In the event that Sellers
appeal such  reassessment,  Sellers shall pay all fees and costs associated with
such contest and Buyer shall only be entitled to reimbursement  upon the earlier
of (i) the  receipt  of a  finally  adjudicated  decision  with  regard  to such
reassessment or (ii) Sellers' deciding to pay the amount of such reassessment.

      t) S  Corporation  Election.  Considering  Sellers'  representation  under
Section 4(y)(i) and under any other provisions of this Agreement relating to the
Company's S Corporation status between April 1, 1996 and Closing,  Sellers shall
continue to diligently  pursue any and all means  available  which would lead to
final confirmation  regarding the validity of this election,  in accordance with
the Covenants  (as defined in this  Agreement).  For purposes of  clarification,
nothing in this Section 6(t) shall operate so as to affect or diminish any other
provisions of this Agreement.

      SECTION 7.  DELIVERIES BY SELLERS ON THE CLOSING DATE.

      On or prior to the Closing Date, Sellers shall satisfy the following:

      a) Stock  Certificates.  On the Closing Date, Sellers shall have delivered

performance of their respective obligations  hereunder.  Sellers shall also have

      SECTION 9.  NATURE AND  SURVIVAL OF  REPRESENTATIONS  AND  WARRANTIES;
                  INDEMNIFICATION, ETC.

      Except  as they  relate  to  Sections  3,  6(a),  6(c) and the  Employment
Agreements  attached  hereto as Exhibits  (which  shall be several and not joint
representations  and  undertakings  of the individual  Sellers),  all statements
contained in any Schedule,  Annex or Exhibit  hereto  (except for the Employment
Agreements)  or in any  certificate  delivered  by or on behalf  of the  parties
pursuant to this Agreement or in connection with the  transactions  contemplated
hereby shall be deemed representations and warranties by the parties hereunder.

      a) Survival  of  Representations,  Warranties,  Etc.  Except as  otherwise
provided herein,  the  representations  and warranties made in this Agreement or
provided  herein shall  survive for two (2) years  following  the Closing  Date,
notwithstanding  any investigation at any time made by or on behalf of the other
party; provided, that:

            i)    all  representations and warranties made by Sellers in Section
                  4(r)  (Environmental  Matters),  4(u) (Employee  Benefits) and
                  4(x)   (Compliance   with  Laws),   shall  survive  until  the
                  applicable  period  for  the  statute  of  limitation  (or any
                  extension  thereof)  has  expired  (as the  case  may be,  the
                  applicable "Survival Period");

            ii)   all  representations  and warranties with respect to any Tax
                  shall  survive the Closing  and shall  terminate  and expire
                  thereafter  on the  later to  occur of (A) the  lapse of the
                  applicable  statute  of  limitations  with  respect  to  the
                  assessment of such Tax (including  any  extensions  thereof)
                  and (B) sixty  (60) days after the final  administrative  or
                  judicial   determination   thereof,  and  no  claim  may  be
                  asserted  thereafter  with the  exception of claims  arising
                  out of any fact,  circumstance,  action,  or  proceeding  to
                  which  the party  asserting  such  claim  shall  have  given
                  notice to the other parties to this  Agreement  prior to the
                  termination of such period of the  reasonable  belief that a
                  Tax  or  other  item   described  in  this   Agreement  will
                  subsequently arise therefrom;



<PAGE>


            iii)  if any  representation  or warranty made in this  Agreement or
                  provided for herein is  fraudulently  given,  it shall survive
                  the Closing Date for an unlimited period of time; and

            iv)   any specific claim or action of which specific notice is given
                  to the party which made such representation or warranty, prior
                  to the  date on which  representation  or  warranty  otherwise
                  terminates as provided herein, may continue to be asserted.

      b) Nature of  Sellers'  Liability.  Each  Seller  shall be liable to Buyer
under  Section 3, 6(a) and 6(c)  hereof  only for a breach by such Seller of his
representations, warranties and covenants contained therein. With respect to all
other  representations,  warranties  and  covenants  made  by  Sellers  in  this
Agreement  or as  provided  herein  (other than in Section 3, 6(a) and 6(c)) the
liabilities of Sellers shall be joint and several.

      c)  Sellers'  Agreement  to  Indemnify.  Subject  to  the  limitations  on
liability set forth in Section 9(d) below, each Seller shall fully indemnify and
hold harmless Buyer, its subsidiaries  (including the Company) and to the extent
Buyer is  required to  indemnify  them,  all  Affiliates,  officers,  directors,
employees,  representatives and agents of Buyer and its Subsidiaries against and
in respect of any and all liabilities, losses, damages, deficiencies, penalties,
fines, costs or expenses (including,  without limitation,  the fees and expenses
of investigation  and counsel)  (collectively  "Losses")  resulting from (A) any
misrepresentation or breach of warranty or the non-fulfillment of any agreement,
covenant or obligation by Sellers made in this Agreement  (excluding Sections 3,
6(a),  6(c) and the  Employment  Agreements  attached  hereto  as  Exhibits  but
including,  without limitation, the Schedules, Annexes and other Exhibits hereto
and the certificates delivered hereunder) or as provided herein, and (B) any and
all actions, suits,  proceedings,  claims, demands,  assessments,  and judgments
incidental to the foregoing or the enforcement of such indemnification.

      d)  Limitation  on Liability of Sellers.  Sellers  shall not be subject to
liability under 9(c)(i) for any  misrepresentation  or breach of warranty unless
and until any and all of Buyer's  Losses  exceed  $25,000 in the  aggregate,  in
which case  Sellers  shall be liable  for the full  amount of such  Losses.  For
purposes of clarification, it is specifically understood that no indemnification
shall arise with respect to Section 4(j) hereof until the amount of  uncollected
receivables  within 90 days of the date of invoice  exceeds the bad debt reserve
set forth on the Balance Sheet.  It is also  understood  that the maximum amount
for which each Seller  shall be liable  under this Section 9 shall be the amount
of the Purchase Price which such Seller received.



<PAGE>


      e) Buyer's  Agreement to  Indemnify.  Buyer will fully  indemnify and hold
harmless  Sellers  against and in respect of any and all of Sellers'  Losses (i)
resulting   from  any   misrepresentation   or   breach  of   warranty   or  the
non-fulfillment  of any agreement,  covenant or obligation by Buyer made in this
Agreement (including,  without limitation,  the Schedules,  Annexes and Exhibits
hereto and the certificates  delivered hereunder) or as provided herein and (ii)
arising  out of the conduct of the  business  of the Company  from and after the
date  hereof,  except to the extent any such Loss arises out of or is related to
any matter for which Buyer is entitled to be indemnified  by Sellers  hereunder.
It is  specifically  understood  that if Buyer  and  Sellers  make  the  Section
338(h)(10)  Election  as  described  in this  Agreement  and  Sellers  incur tax
liability  in excess of that which they would have  incurred if the election was
not made, Buyer will indemnify Sellers for such additional tax liability.

      f) Third Party Claims.  Promptly  after the receipt by any party hereto of
notice of any claim,  action,  suit or  proceeding  of any third  party which is
subject to  indemnification  hereunder,  such party or parties (the "Indemnified
Party")  shall  give  written  notice of such claim (a "Notice of Claim") to the
party  obligated  to  provide  indemnification   hereunder  (collectively,   the
"Indemnifying Party"), stating the nature and basis of such claim and the amount
thereof,  to the extent  known.  The  Indemnifying  Party  shall be  entitled to
participate in the defense or settlement of such matter and the parties agree to
cooperate in any such defense or  settlement  and to give each other full access
to all  information  relevant  thereto.  The  Indemnifying  Party  shall  not be
obligated to indemnify an Indemnified Party hereunder for any settlement entered
into without the Indemnifying Party's prior written consent, which consent shall
not be  unreasonably  withheld,  conditioned  or delayed.  If the loss  incurred
relates  to the  failure  of the Buyer or the  Company  to  collect  any note or
account  receivable and if any Sellers pay in full the unpaid balance thereof to
the Buyer or the  Company,  the Buyer will cause the Company to assign said note
or account without  recourse to the Sellers paying same in full  satisfaction of
the Sellers' indemnification  obligation as to such uncollected note or account.
Any collection  procedures by Sellers will be carried out in a reasonable manner
with prior notice to Buyer so as not to  prejudice  the  Company's  relationship
with the account debtor.

      SECTION 10. PAYMENT OF CERTAIN EXPENSES.

      Sellers will pay all federal,  state,  county and local Taxes  (including,
without limitation, any requisite transfer taxes) which may be payable by reason
of the  consummation  of the  purchase  and sale of the  Shares.  Subject to the
foregoing,  each party will be liable for its own costs and expenses incurred in
connection with the negotiation,  preparation,  execution or performance of this
Agreement and the transactions contemplated hereby.



<PAGE>


      SECTION 11. INJUNCTIVE RELIEF.

      Sellers acknowledge that irreparable damage would result if the provisions
of Sections  6(a),  (b) or (c) were not complied with in  accordance  with their
respective specific terms. Accordingly,  Sellers agree that Buyer shall have the
right,  in addition to any other rights or remedies it may have,  to  injunctive
relief,  without the  necessity of posting a bond,  in respect of any failure on
the part of Sellers and to comply with provisions of Sections 6(a), (b) or (c).

      SECTION 12. WAIVER.

      Any of the terms or conditions of this Agreement may be waived at any time
and from time to time in writing by the party  entitled to the benefits  thereof
without affecting any other terms or conditions of this Agreement.

transfer to and vest in Buyer good and marketable title to the Shares,  free and
clear of all such Encumbrances.

      viii) Except as disclosed on Schedule 4(a) of the  Agreement,  neither the
execution and delivery of the Agreement,  the  consummation of the  transactions
contemplated  thereby,  nor compliance by Sellers or the Company with any of the
provisions   thereof  will  (A)  violate  or  conflict   with  the  Articles  of
Incorporation or Bylaws of the Company, (B) violate,  conflict with, result in a
breach of,  constitute a default (or an event which with the giving of notice or

                                  ARTICLE III
                          CLAIMS AGAINST ESCROW FUND


<PAGE>


      Section III.1 Award Fee Escrow Fund  Disbursement.  The parties agree that
the Award Fee Escrow Fund applies to the award fee determinations  which will be
granted  by NASA for the  following  operating  periods:  (a)  April 1,  1998 to
September 30, 1998;  (b) October 1, 1998 to March 31, 1999; (c) April 1, 1999 to
September 30, 1999; (d) October 1, 1999 to March 31, 2000; and (e) April 1, 2000
to September  30,  2000.  Within 10 days of receipt by the Company of payment by
NASA of the award fee attributable to any of the above-referenced periods, Buyer
and two out of three Sellers shall  prepare a  Certificate  (the  "Certificate")
authorizing the release of a portion of the Award Fee Escrow Fund as follows: if
the award fee score  underlying  this  period is 85 or  higher,  Seller  will be
entitled  to  withdraw  and  receive  payment of Six  Hundred  Thousand  Dollars
($600,000)  plus the interest  thereon net of taxes paid,  and, if the award fee
score is less than 85,  Buyer will be entitled to withdraw  the same amount from
the Award Fee  Escrow  Fund.  Accordingly,  the  Award Fee  Escrow  Fund will be
depleted when the  appropriate  party  withdraws the amount  attributable to the
operating period ending September 30, 2000.

                                  ARTICLE IV
                            RESOLUTION OF DISPUTES
      Section  IV.1 If a  dispute  arises  between  Sellers  and Buyer as to the
application,  interpretation  or operation  of this Award Fee Escrow  Agreement,
Sellers  and Buyer  shall  attempt in good faith to agree upon the rights of the
respective parties with respect to such dispute.  If Sellers and Buyer so agree,
a memorandum  setting forth such agreement shall be prepared and signed by Buyer
and  Sellers  and  shall  be  furnished  to  each  of  them,  and a  Certificate
summarizing this agreement and signed by Buyer and two out of three Sellers will
be presented to the Escrow Agent.


<PAGE>


      Section  IV.2  If no  such  agreement  can be  reached  after  good  faith
negotiation,  but in any event 30 days  after  Sellers  refuse to consent to the
delivery  of a portion of the Escrow Fund for the amount of a Loss in respect of
any Claim  made by Buyer (a  "Dispute"),  such  Dispute  shall be  submitted  to
mandatory  and binding  arbitration.  The  arbitration  shall be pursuant to the
Commercial  Arbitration  Rules  of the  American  Arbitration  Association  (the
"AAA").  The arbitration  hearing shall be held in such neutral  location as the
parties may mutually agree or, in the absence of mutual  agreement,  in New York
City.  The  arbitration  panel  will  have no  power  or  authority,  under  the
Commercial  Arbitration  Rules of the AAA or  otherwise,  to relieve the parties
from their  agreement  hereunder to arbitrate or otherwise to amend or disregard
any provision of this Agreement, including without limitation, the provisions of
this  Section 4.2. Any award  rendered by the  arbitration  panel will be final,
conclusive  and binding upon the parties and any judgment  hereon may be entered
and enforced in any court of competent jurisdiction.
      Section IV.3 If at any time there shall arise a dispute between any or all
of the Sellers  concerning  which of them shall be liable for payment of a Claim
or Claims, Sellers hereby expressly acknowledge and agree that: (i) such dispute
will not in any way whatsoever delay the delivery,  in the ordinary  course,  to
Buyer of any amount out of the Escrow Fund pursuant to Article III hereof;  (ii)
Sellers  shall  attempt in good faith to agree upon their rights with respect to
each such Claim;  (iii) if all Sellers so agree, a memorandum setting forth such
agreement  shall be prepared and signed by Sellers and shall be furnished to the
Escrow Agent and Buyer;  and (iv) if no such agreement can be reached after good
faith  negotiation,  but in any event 30 days after either,  as the case may be,
raises a dispute as  referenced  in this Section 4.3,  then the dispute shall be
submitted to binding  arbitration  before an arbitrator or arbitrators  mutually
agreed to by the Sellers.

                                   ARTICLE V
                          EXPIRATION OF ESCROW PERIOD


<PAGE>


      If, upon  expiration  of the Escrow  Period,  Buyer shall have  asserted a
Claim and such Claim is pending or  unresolved  at the time of such  expiration,
the Escrow  Agent  shall  retain in the Escrow  Fund that  portion of the Escrow
Amount,  net of any  distributions  made or to be made  with  respect  to  other
Claims,  equal in value to the  disbursement  asserted  in such Claim until such
matter is resolved.  If it is  determined  that Buyer is entitled to recovery on
account of such  disbursement,  the Escrow  Agent  shall  deliver or cause to be
delivered to Buyer the Escrow  Amount having a value equal to the amount due and
payable with respect to such Claim, plus the interest thereon net of taxes paid.
In the event that no Claims,  or notices as  provided  in Article II are made or
pending by or at the end of the Escrow Period, the remaining value of the Escrow
Fund net of Expenses and taxes shall be disbursed to the Sellers as follows:
William A. Jackson (40%), Eugene A. Cernan (30%) and W.
T. Short (30%).

                                  ARTICLE VI
                      SCHEDULE FOR RELEASE OF ESCROW FUND
      If any amount is paid by the Escrow Agent pursuant to a  disbursement  and
the actual  disbursements  with respect thereto are at the time determined to be
less than such payment,  Buyer shall  promptly  return such excess to the Escrow
Agent to be deposited into the Escrow Fund, if this Escrow  Agreement is then in
effect, or to Sellers,  as the case may be, in accordance with the provisions of
this Article V, if this Escrow Agreement is no longer in effect.

                                 ARTICLE VIII
                  ESCROW AGENT'S RIGHTS AND RESPONSIBILITIES
      To induce the Escrow Agent to act hereunder, it is further agreed that:
            (a)   Any  recitals  contained in this Escrow  Agreement  shall be
      deemed to be those of the principals and not those of the Escrow Agent.
            (b)   The  Escrow  Agent  shall  not be under any duty to give the
      property held  hereunder any greater  degree of care than it gives its own
      similar property.
            (c) The Escrow Agent may engage legal counsel who may be counsel for
      any party to the Escrow  Agreement  and may act upon  advice of counsel in
      reference to any matter connected herewith and shall not be liable for any
      acts or  omissions  taken or  suffered  pursuant  to the  opinion  of such
      counsel.  The fees and  expenses of such  counsel  shall be deemed to be a
      proper  expense  for which the Escrow  Agent will have a lien  against the
      Escrow Fund.


<PAGE>


            (d) The Escrow  Agent  shall not be liable in any respect on account
      of  the  identity,  authority  or  rights  of  the  parties  executing  or
      delivering or  purporting  to execute or deliver this Escrow  Agreement or
      any  documents  or papers  deposited or called for  hereunder.  The Escrow
      Agent shall be  protected  in acting upon any  notice,  request,  consent,
      certificate, order, affidavit, letter, telegram or other paper or document
      believed  by it to be genuine  and correct and to have been signed or sent
      by the proper person or persons.
            (e) The Escrow  Agent shall not be liable for the  outlawing  of any
      rights  under any  statute of  limitations  with  respect  to this  Escrow
      Agreement or any documents deposited with the Escrow Agent.
            (f) The Escrow Agent is hereby expressly authorized to disregard any
      and all  warnings  given  by any of the  parties  hereto  or by any  other
      person,  excepting  only orders or process of courts of law, and is hereby
      expressly authorized to comply with and obey orders,  judgments or decrees
      of any court.  In case the Escrow  Agent obeys or  complies  with any such
      order,  judgment  or decree of any court,  the Escrow  Agent  shall not be
      liable to any of the  parties  hereto or to any other  person by reason of
      such compliance,  notwithstanding any such order, judgment or decree being
      subsequently reversed,  modified, annulled, set aside, vacated or found to
      have been entered without jurisdiction.
            (g)  The  Escrow  Agent  is   authorized  to  rely  on  the  written
      instructions of Sellers as being the acts,  respectively,  of Sellers, and
      the written instructions of the Chief Executive Officer or Chief Financial
      Officer of Buyer as being the act of Buyer.


<PAGE>


            (h) The duties of the Escrow Agent shall be as expressed  under this
      Escrow Agreement,  and the Escrow Agent shall have no implied duties.  The
      permissive  right or power to take any action  shall not be construed as a
      duty to take action  under any  circumstances,  and the Escrow Agent shall
      not be  liable  except in the event of its  gross  negligence  or  willful
      misconduct.
            (i) The Escrow Agent shall not be called upon to advise any party as
      to its rights and obligations hereunder.
            (j) In  consideration  of its  acceptance of the  appointment as the
      Escrow  Agent,  and except  with  respect to the Escrow  Agent's own gross
      negligence or willful  misconduct or acts or omissions by the Escrow Agent
      not in good faith, the other parties hereto agree,  jointly and severally,
      to  indemnify  and  hold  the  Escrow  Agent  harmless  as to any  loss or
      liability  incurred by it to any person,  firm or corporation by reason of
      its having  accepted the same or in carrying out any of the terms  hereof,
      and to  reimburse  the  Escrow  Agent  for  all  its  expenses,  including
      attorney's fees,  incurred by reason of its position  hereunder or actions
      taken pursuant hereto.  The Escrow Agent shall have no liability under, or
      duty to inquire into, the terms and  provisions of this Escrow  Agreement,
      and it is agreed that its duties are purely ministerial in nature and that
      the Escrow  Agent shall incur no liability  whatsoever  except for willful
      misconduct or gross negligence so long as it has acted in good faith. This
      paragraph (j) shall survive the termination of the Escrow Agreement.
            (k) The Escrow Agent may execute any of the duties under this Escrow
      Agreement by or through agents or receivers.
            (l) Unless  specifically  required  by this  Escrow  Agreement,  the
      Escrow Agent shall not be required to give any bond or surety or report to
      any court despite any statute, custom or rule to the contrary.


<PAGE>


            (m) In the event the Escrow Agent becomes  involved in litigation by
      reason  hereof,  it is hereby  authorized to deposit with the clerk of the
      court in which the litigation is pending any and all funds,  securities or
      other  property held by it pursuant  hereto,  less its fees,  expenses and
      advances,  and thereupon  shall stand fully relieved and discharged of any
      further  duties  hereunder.  Also,  in  the  event  the  Escrow  Agent  is
      threatened  with litigation by reason hereof,  it is hereby  authorized to
      implead all interested parties in any court of competent  jurisdiction and
      to deposit  with the clerk of such  court any such  funds,  securities  or
      other  property held by it pursuant  hereto,  less its fees,  expenses and
      advances,  and thereupon  shall stand fully relieved and discharged of any
      further duties hereunder.
            (n) The Escrow Agent shall not be obligated to risk its own funds in
      the  administration  of the Escrow Fund and shall have a lien  against any
      funds,  securities or other  property in its possession or control for its
      fees, expenses and advancements. The Escrow Agent need not take any action
      under  this  Escrow  Agreement  which may  involve  it in any  expense  or
      liability  until  indemnified  to its  satisfaction  for  any  expense  or
      liability it reasonably believes it may occur.

                                  ARTICLE IX
                                    RECORDS
      The Escrow Agent shall  maintain a record of all Claims against the Escrow
Fund filed with it  pursuant to Article  III, a record of all such claims  which
shall  become  payable  as  provided  in  Article  III or IV and a record of all
payments from the Escrow Fund to Buyer.

                                   ARTICLE X
                          RESIGNATION OF ESCROW AGENT


<PAGE>


      The Escrow Agent,  or any successor,  may resign as Escrow Agent hereunder
by giving 30 days' written  notice thereof to Buyer and Sellers by registered or
certified mail. Such resignation  shall become effective  following such written
notice upon the earlier of the  appointment  by Buyer and Sellers of a successor
Escrow  Agent  that  accepts  the  appointment  and  agrees  to be  bound by the
provisions of this Agreement or the expiration of 30 days  thereafter.  Upon the
effectiveness of such  resignation,  all duties of the Escrow Agent so resigning
shall cease,  other than the duty to account in  accordance  with Article  VIII.
Buyer and  Sellers  shall have the right to  terminate  the  appointment  of the
Escrow Agent  hereunder by giving  written  notice  thereof to the Escrow Agent,
specifying the date upon which such  termination  shall take effect. A condition
precedent to such  termination  shall be the  designation of a successor  Escrow
Agent that has accepted the appointment and agreed to be bound by the provisions
of this  Agreement.  In event of such  termination,  the Escrow Agent shall turn
over and deliver to such  successor  Escrow Agent the Escrow Fund, and any other
sums and the records and instruments  held by it under this Escrow Agreement and
render the accounting required by Article VIII.

                                  ARTICLE XI

                          First Union National Bank, NA






            THIS BLANKET ESCROW AGREEMENT (the "Escrow  Agreement")  dated as of
July  1,  1998,  is made  by and  among  SPACEHAB,  INCORPORATED,  a  Washington
corporation  ("Buyer"),  William A.  Jackson,  Eugene A. Cernan and W.T.  Short,
(individually  "Seller" and  collectively  "Sellers")  and First Union  National
Bank, a national banking  association  (the "Escrow Agent"),  as contemplated by
that certain Stock  Purchase  Agreement,  dated as of July 1, 1998, by and among
Sellers and Buyer. Capitalized terms not otherwise defined herein shall have the
meanings ascribed to them in the Stock Purchase Agreement
      WHEREAS, Buyer and Sellers have entered into the Stock Purchase Agreement,
dated as of July 1, 1998,  to provide  for the  purchase of all of the Shares of
the Company;
      WHEREAS,  Sellers have agreed to indemnify Buyer in certain  circumstances
pursuant to Section 9 of the Stock Purchase Agreement;
      WHEREAS,  the  closing  of the  transactions  contemplated  by  the  Stock
Purchase  Agreement  are taking place as of the date hereof and the execution of
this Escrow Agreement by the parties is an express condition thereto; and
      WHEREAS,  Buyer  has  relied  upon  the  representations,  warranties  and
covenants  of  Sellers  provided  in the  Stock  Purchase  Agreement  and in the
Schedules, Annexes, Exhibits Certificates and other documents delivered pursuant
to the Stock Purchase Agreement.


<PAGE>



                                   IV-A - 4

      NOW,  THEREFORE,  to induce  Buyer to  proceed  with the  Closing  and the
acquisition  of all of the Shares of the  Company and in  consideration  of such
Closing and  acquisition,  and in further  consideration of the mutual covenants
and  agreements  contained  herein  and in the  Stock  Purchase  Agreement,  and
intending to be legally bound, the parties hereto do hereby agree as follows:
                                   ARTICLE I
      Section 1.1.  Contemporaneous with the execution of this Escrow Agreement,
Buyer shall deposit at Closing, by wire transfer of immediately available funds,
Two Million Five Hundred  Thousand  Dollars  ($2,500,000) of the Purchase Price,
representing  the sum of the  Blanket  Escrow Fund with the Escrow  Agent,  such
deposit to constitute  an escrow fund (the "Escrow  Fund") to be governed by the
terms set forth herein,  it being  understood  that any interest or other income
thereon will also form part of the Escrow Fund.  The interest  shall be reported
as income to Buyer and Buyer shall be entitled  to receive a  distribution  from
the  Escrow  Fund each  year in an amount  sufficient  to pay the  income  taxes
thereon  calculated at the highest  corporate  rate (giving  effect to state and
local income taxes).  The  disbursement  of any interest  income,  net of income
taxes paid, will be distributed in proportional  amounts to the party or parties
to whom the amounts deposited into the Escrow Fund upon execution of this Escrow
Agreement are actually  paid. The Escrow Agent shall invest the Escrow Amount in
interest bearing United States government  securities or mutual funds consisting
of United  States  government  securities  and  repurchase  agreements  having a
maturity not exceeding the Escrow Period. Upon compliance with the terms hereof,
Buyer shall be entitled to receive  payment  from the Escrow Fund for all Losses
for  which  Buyer is  entitled  to  indemnification  under  the  Stock  Purchase
Agreement.
      Section  1.2. The Escrow  Agent shall hold,  safeguard  and dispose of the
Escrow Fund in accordance with the terms hereof and shall treat such Escrow Fund
as an escrow fund in accordance with the terms hereof and not as the property of
Buyer or Sellers.


<PAGE>


                                  ARTICLE II
                                 ESCROW PERIOD
      The funds  forming the Escrow Fund shall remain in existence  for a period
ending on July 1,  2000  (the  "Escrow  Period")  and no claim  may be  asserted
thereafter  with the exception of claims arising out of any fact,  circumstance,
action,  or proceeding to which the party  asserting such claim shall have given
to the other parties to this Agreement, prior to the termination of such period,
notice of the  reasonable  belief that an item  described in this Agreement will
subsequently arise; provided, however, that any element of the Escrow Fund shall
continue to be  maintained  beyond the Escrow  Period to the extent set forth in
Article V hereof,  in the event  that  there  exists  any Claim (as  defined  in
Article III hereof) that is pending or not yet  resolved  pursuant to Article IV
hereof.
                                  ARTICLE III

existence  of a  certificate  signed by the  Chief  Executive  Officer  or Chief
Financial  Officer of Buyer  ("Officer's  Certificate")  and by two of the three
Sellers:
            (a)  stating  that  Buyer has a Loss and that Buyer is  entitled  to
      indemnification  out of the Escrow Fund pursuant to this Escrow  Agreement
      and Section 9 of the Stock  Purchase  Agreement  other than as a result of
      the specific  items  covered by the Award Fee Escrow Fund or the Deduction
      Escrow Fund; and


<PAGE>


            (b) specifying in reasonable detail (i) the amount of the Loss; (ii)
      the individual items of Losses included in the amount so stated; (iii) the
      basis for the Loss and (iv) the section of the Stock Purchase Agreement to
      which such claim relates;
the Escrow Agent shall, subject to the provisions of Article IV hereof,  deliver
to Buyer, as promptly as practicable, out of the Escrow Fund, such amount out of
the Escrow Fund having a value  equal to the amount of such  Losses.  The Escrow
Agent shall make no delivery out of the Escrow Fund pursuant to this Article III
unless the Escrow Agent shall have received the Officer's  Certificate specified
in this Section 3.1 to make such delivery.
      SECTION  3.2.  Claims.  Any claim by Buyer  against the Escrow Fund made
in an Officer's  Certificate pursuant to this Article III shall be referred to
herein as a "Claim" or, if multiple, "Claims."
                                  ARTICLE IV
                            RESOLUTION OF DISPUTES
      SECTION  4.1. If the Sellers  shall not have  consented to the delivery to
Buyer of that  portion  of the  Escrow  Fund  equal to the  amount  of Losses in
respect of any Claim made in an Officer's  Certificate  pursuant to Article III,
Sellers  and Buyer  shall  attempt in good faith to agree upon the rights of the
respective  parties  with  respect to each such  Claim.  If Sellers and Buyer so
agree, a memorandum setting forth such agreement shall be prepared and signed by
Buyer  and  Sellers  and  shall be  furnished  to each of them and an  Officer's
Certificate will be presented to the Escrow Agent.


<PAGE>


      SECTION  4.2.  If no  such  agreement  can be  reached  after  good  faith
negotiation,  but in any event 30 days  after  Sellers  refuse to consent to the
delivery  of a portion of the Escrow Fund for the amount of a Loss in respect of
any Claim  made by Buyer (a  "Dispute"),  such  Dispute  shall be  submitted  to
mandatory  and binding  arbitration.  The  arbitration  shall be pursuant to the
Commercial  Arbitration  Rules  of the  American  Arbitration  Association  (the
"AAA").  The arbitration  hearing shall be held in such neutral  location as the
parties may mutually agree or, in the absence of mutual  agreement,  in New York
City.  The  arbitration  panel  will  have no  power  or  authority,  under  the
Commercial  Arbitration  Rules of the AAA or  otherwise,  to relieve the parties
from their  agreement  hereunder to arbitrate or otherwise to amend or disregard
any provision of this Agreement, including without limitation, the provisions of
this  Section 4.2. Any award  rendered by the  arbitration  panel will be final,
conclusive  and binding upon the parties and any judgment  hereon may be entered
and enforced in any court of competent jurisdiction.
      SECTION 4.3. If at any time there shall arise a dispute between any or all
of the Sellers  concerning  which of them shall be liable for payment of a Claim
or Claims, Sellers hereby expressly acknowledge and agree that: (i) such dispute
will not in any way whatsoever delay the delivery,  in the ordinary  course,  to
Buyer of any amount out of the Escrow Fund pursuant to Article III hereof;  (ii)
Sellers  shall  attempt in good faith to agree upon their rights with respect to
each such Claim;  (iii) if all Sellers so agree, a memorandum setting forth such
agreement  shall be prepared and signed by Sellers and shall be furnished to the
Escrow Agent and Buyer;  and (iv) if no such agreement can be reached after good
faith  negotiation,  but in any event 30 days after either,  as the case may be,
raises a dispute as  referenced  in this Section 4.3,  then the dispute shall be
submitted to binding  arbitration  before an arbitrator or arbitrators  mutually
agreed to by the Sellers.

                                   ARTICLE V
                          EXPIRATION OF ESCROW PERIOD
      If, upon  expiration  of the Escrow  Period,  Buyer shall have  asserted a
Claim and such Claim is pending or  unresolved  at the time of such  expiration,
the Escrow  Agent  shall  retain in the Escrow  Fund that  portion of the Escrow
Amount,  net of any  distributions  made or to be made  with  respect  to  other
Claims,  equal in value to the Loss  asserted in such Claim until such matter is
resolved.  If it is determined  that Buyer is entitled to recovery on account of
such Claim, the Escrow Agent shall deliver or cause to be delivered to Buyer the
Escrow Amount having a value equal to the amount due and payable with respect to
such Claim plus the  interest  thereof net of taxes  paid.  In the event that no
Claims,  or notices as  provided in Article II, are made or are pending by or at
the end of the Escrow  Period,  the remaining  value of the Escrow Fund,  net of
expenses and taxes shall be disbursed to the Sellers as follows: William A.
Jackson (40%), Eugene A. Cernan (30%) and W.
T. Short (30%).
                                  ARTICLE VI
                      SCHEDULE FOR RELEASE OF ESCROW FUND
      If any  amount is paid by the  Escrow  Agent  pursuant  to a Claim and the
actual  Losses with respect to such Claim are at the time  determined to be less
than such payment,  Buyer shall promptly  return such excess to the Escrow Agent
to be  deposited  into the Escrow  Fund,  if this  Escrow  Agreement  is then in
effect, or to Sellers,  as the case may be, in accordance with the provisions of
this Article V, if this Escrow Agreement is no longer in effect.

                                 ARTICLE VIII
                  ESCROW AGENT'S RIGHTS AND RESPONSIBILITIES
      To induce the Escrow Agent to act hereunder, it is further agreed that:
            (a)   Any  recitals  contained in this Escrow  Agreement  shall be
      deemed to be those of the principals and not those of the Escrow Agent.
            (b)   The  Escrow  Agent  shall  not be under any duty to give the
      property held  hereunder any greater  degree of care than it gives its own
      similar property.
            (c) The Escrow Agent may engage legal counsel who may be counsel for
      any party to the Escrow  Agreement  and may act upon  advice of counsel in
      reference to any matter connected herewith and shall not be liable for any
      acts or  omissions  taken or  suffered  pursuant  to the  opinion  of such
      counsel.  The fees and  expenses of such  counsel  shall be deemed to be a
      proper  expense  for which the Escrow  Agent will have a lien  against the
      Escrow Fund.
            (d) The Escrow  Agent  shall not be liable in any respect on account
      of  the  identity,  authority  or  rights  of  the  parties  executing  or
      delivering or  purporting  to execute or deliver this Escrow  Agreement or
      any  documents  or papers  deposited or called for  hereunder.  The Escrow
      Agent shall be  protected  in acting upon any  notice,  request,  consent,
      certificate, order, affidavit, letter, telegram or other paper or document
      believed  by it to be genuine  and correct and to have been signed or sent
      by the proper person or persons.
            (e) The Escrow  Agent shall not be liable for the  outlawing  of any
      rights  under any  statute of  limitations  with  respect  to this  Escrow
      Agreement or any documents deposited with the Escrow Agent.


<PAGE>


            (f) The Escrow Agent is hereby expressly authorized to disregard any
      and all  warnings  given  by any of the  parties  hereto  or by any  other
      person,  excepting  only orders or process of courts of law, and is hereby
      expressly authorized to comply with and obey orders,  judgments or decrees
      of any court.  In case the Escrow  Agent obeys or  complies  with any such
      order,  judgment  or decree of any court,  the Escrow  Agent  shall not be
      liable to any of the  parties  hereto or to any other  person by reason of
      such compliance,  notwithstanding any such order, judgment or decree being
      subsequently reversed,  modified, annulled, set aside, vacated or found to
      have been entered without jurisdiction.
            (g)  The  Escrow  Agent  is   authorized  to  rely  on  the  written
      instructions of Sellers as being the acts,  respectively,  of Sellers, and
      the written instructions of the Chief Executive Officer or Chief Financial
      Officer of Buyer as being the act of Buyer.
            (h) The duties of the Escrow Agent shall be as expressed  under this
      Escrow Agreement,  and the Escrow Agent shall have no implied duties.  The
      permissive  right or power to take any action  shall not be construed as a
      duty to take action  under any  circumstances,  and the Escrow Agent shall
      not be  liable  except in the event of its  gross  negligence  or  willful
      misconduct.
            (i) The Escrow Agent shall not be called upon to advise any party as
      to its rights and obligations hereunder.


<PAGE>


            (j) In  consideration  of its  acceptance of the  appointment as the
      Escrow  Agent,  and except  with  respect to the Escrow  Agent's own gross
      negligence or willful  misconduct or acts or omissions by the Escrow Agent
      not in good faith, the other parties hereto agree,  jointly and severally,
      to  indemnify  and  hold  the  Escrow  Agent  harmless  as to any  loss or
      liability  incurred by it to any person,  firm or corporation by reason of
      its having  accepted the same or in carrying out any of the terms  hereof,
      and to  reimburse  the  Escrow  Agent  for  all  its  expenses,  including
      attorney's fees,  incurred by reason of its position  hereunder or actions
      taken pursuant hereto.  The Escrow Agent shall have no liability under, or
      duty to inquire into, the terms and  provisions of this Escrow  Agreement,
      and it is agreed that its duties are purely ministerial in nature and that
      the Escrow  Agent shall incur no liability  whatsoever  except for willful
      misconduct or gross negligence so long as it has acted in good faith. This
      paragraph (j) shall survive the termination of the Escrow Agreement.
            (k) The Escrow Agent may execute any of the duties under this Escrow
      Agreement by or through agents or receivers.
            (l) Unless  specifically  required  by this  Escrow  Agreement,  the
      Escrow Agent shall not be required to give any bond or surety or report to
      any court despite any statute, custom or rule to the contrary.
            (m) In the event the Escrow Agent becomes  involved in litigation by
      reason  hereof,  it is hereby  authorized to deposit with the clerk of the
      court in which the litigation is pending any and all funds,  securities or
      other  property held by it pursuant  hereto,  less its fees,  expenses and
      advances,  and thereupon  shall stand fully relieved and discharged of any
      further  duties  hereunder.  Also,  in  the  event  the  Escrow  Agent  is
      threatened  with litigation by reason hereof,  it is hereby  authorized to
      implead all interested parties in any court of competent  jurisdiction and
      to deposit  with the clerk of such  court any such  funds,  securities  or
      other  property held by it pursuant  hereto,  less its fees,  expenses and
      advances,  and thereupon  shall stand fully relieved and discharged of any
      further duties hereunder.


<PAGE>


            (n) The Escrow Agent shall not be obligated to risk its own funds in
      the  administration  of the Escrow Fund and shall have a lien  against any
      funds,  securities or other  property in its possession or control for its
      fees, expenses and advancements. The Escrow Agent need not take any action
      under  this  Escrow  Agreement  which may  involve  it in any  expense  or
      liability  until  indemnified  to its  satisfaction  for  any  expense  or
      liability it reasonably believes it may occur.
                                  ARTICLE IX
                                    RECORDS
      The Escrow Agent shall  maintain a record of all Claims against the Escrow
Fund filed with it  pursuant to Article  III, a record of all such claims  which
shall  become  payable  as  provided  in  Article  III or IV and a record of all
payments from the Escrow Fund to Buyer.
                                   ARTICLE X
                          RESIGNATION OF ESCROW AGENT


<PAGE>


      The Escrow Agent,  or any successor,  may resign as Escrow Agent hereunder
by giving 30 days' written  notice thereof to Buyer and Sellers by registered or
certified mail. Such resignation  shall become effective  following such written
notice upon the earlier of the  appointment  by Buyer and Sellers of a successor
Escrow  Agent  that  accepts  the  appointment  and  agrees  to be  bound by the
provisions of this Agreement or the expiration of 30 days  thereafter.  Upon the
effectiveness of such  resignation,  all duties of the Escrow Agent so resigning
shall cease,  other than the duty to account in  accordance  with Article  VIII.
Buyer and  Sellers  shall have the right to  terminate  the  appointment  of the
Escrow Agent  hereunder by giving  written  notice  thereof to the Escrow Agent,
specifying the date upon which such  termination  shall take effect. A condition
precedent to such  termination  shall be the  designation of a successor  Escrow
Agent that has accepted the appointment and agreed to be bound by the provisions
of this  Agreement.  In event of such  termination,  the Escrow Agent shall turn
over and deliver to such  successor  Escrow Agent the Escrow Fund, and any other
sums and the records and instruments  held by it under this Escrow Agreement and
render the accounting required by Article VIII.
                                  ARTICLE XI

                                    IV-C-1



      THIS DEDUCTION ESCROW AGREEMENT (the "Escrow  Agreement") dated as of July
1, 1998, is made by and among SPACEHAB,  INCORPORATED,  a Washington corporation
("Buyer"),  William A. Jackson,  Eugene A. Cernan and W.T. Short,  (individually
"Seller" and  collectively  "Sellers") and First Union National Bank, a national
banking  association (the "Escrow Agent"), as contemplated by that certain Stock
Purchase  Agreement,  dated as of July 1, 1998,  by and among Sellers and Buyer.
Capitalized  terms not otherwise defined herein shall have the meanings ascribed
to them in the Stock Purchase Agreement
      WHEREAS, Buyer and Sellers have entered into the Stock Purchase Agreement,
dated as of July 1, 1998,  to provide  for the  purchase of all of the Shares of
the Company;
      WHEREAS,  Sellers have agreed to indemnify Buyer in certain  circumstances
pursuant to Section 9 of the Stock Purchase Agreement;
      WHEREAS,  the  closing  of the  transactions  contemplated  by  the  Stock
Purchase  Agreement  are taking place as of the date hereof and the execution of
this Escrow Agreement by the parties is an express condition thereto; and
      WHEREAS,  Buyer  has  relied  upon  the  representations,  warranties  and
covenants  of  Sellers  provided  in the  Stock  Purchase  Agreement  and in the
Schedules, Annexes, Exhibits Certificates and other documents delivered pursuant
to the Stock Purchase Agreement.


<PAGE>


      NOW,  THEREFORE,  to induce  Buyer to  proceed  with the  Closing  and the
acquisition  of all of the Shares of the  Company and in  consideration  of such
Closing and  acquisition,  and in further  consideration of the mutual covenants
and  agreements  contained  herein  and in the  Stock  Purchase  Agreement,  and
intending to be legally bound, the parties hereto do hereby agree as follows:
                                   ARTICLE I
      Section I.1  Contemporaneous  with the execution of this Escrow Agreement,
Buyer shall deposit at Closing, by wire transfer of immediately available funds,
One Million One Hundred  Thousand  Dollars  ($1,100,000)  of the Purchase Price,
representing the sum of the Deduction Escrow Fund (the "Escrow Amount") with the
Escrow Agent,  such deposit to constitute an escrow fund (the "Escrow  Fund") to
be governed by the terms set forth herein, it being understood that any interest
or other income  thereon  will also form part of the Escrow  Fund.  The interest
shall be  reported  as income to Buyer and Buyer  shall be entitled to receive a
distribution  from the Escrow Fund each year in an amount  sufficient to pay the
income taxes thereon  calculated at the highest corporate rate (giving effect to
state and local income taxes).  The disbursement of any interest income,  net of
income taxes paid, will be distributed in  proportional  amounts to the party or
parties to whom the amounts  deposited  into the Escrow Fund upon  execution  of
this Escrow  Agreement  are  actually  paid.  The Escrow  Agent shall invest the
Escrow Amount in interest bearing United States government  securities or mutual
funds  consisting  of  United  States   government   securities  and  repurchase
agreements  having a maturity not exceeding the Escrow Period.  Upon  compliance
with the terms  hereof,  Buyer  shall be entitled  to receive  payment  from the
Escrow Fund for all Losses for which Buyer is entitled to indemnification  under
the Stock Purchase Agreement.
      Section  I.2 The Escrow  Agent shall  hold,  safeguard  and dispose of the
Escrow Fund in accordance with the terms hereof and shall treat such Escrow Fund
as an escrow fund in accordance with the terms hereof and not as the property of
Buyer or Sellers.

                                  ARTICLE II
                                 ESCROW PERIOD
      The funds  forming the Escrow  Fund shall  remain in  existence  until the

Engineering  Corporation  filed its  federal  income tax return for the tax year
ended March 31, 1995 as evidenced by Internal  Revenue  Service  records or (ii)
December 15, 1998, and no claim may be asserted thereafter with the exception of
claims arising out of any fact, circumstance, action, or proceeding to which the
party  asserting  such  claim  shall  have  given to the other  parties  to this
Agreement,  prior to the  termination  of such period,  notice of the reasonable
belief  that an  item  described  in this  Agreement  will  subsequently  arise;
provided,  however,  that any  element of the Escrow  Fund shall  continue to be
maintained beyond the Escrow Period to the extent set forth in Article V hereof,
in the event that there exists any Claim (as defined in Article III hereof) that
is pending or not yet resolved pursuant to Article IV hereof.

            (b) specifying in reasonable detail (i) the amount of the Loss; (ii)
      the individual items of Losses included in the amount so stated; (iii) the
      basis for the Loss and (iv) the section of the Stock Purchase Agreement to
      which such claim relates;
the Escrow Agent shall, subject to the provisions of Article IV hereof,  deliver
to Buyer, as promptly as practicable, out of the Escrow Fund, such amount out of
the Escrow Fund having a value  equal to the amount of such  Losses.  The Escrow
Agent shall make no delivery out of the Escrow Fund pursuant to this Article III
unless the Escrow Agent shall have received the Officer's  Certificate specified
in this Section 3.1 to make such delivery.
      Section III.2     Claims.  Any claim by Buyer  against  the Escrow  Fund
made in an  Officer's  Certificate  pursuant  to this  Article  III  shall  be
referred to herein as a "Claim" or, if multiple, "Claims."
                                  ARTICLE IV
                            RESOLUTION OF DISPUTES
      Section  IV.1 If the Sellers  shall not have  consented to the delivery to
Buyer of that  portion  of the  Escrow  Fund  equal to the  amount  of Losses in
respect of any Claim made in an Officer's  Certificate  pursuant to Article III,
Sellers  and Buyer  shall  attempt in good faith to agree upon the rights of the
respective  parties  with  respect to each such  Claim.  If Sellers and Buyer so
agree, a memorandum setting forth such agreement shall be prepared and signed by
Buyer  and  Sellers  and  shall be  furnished  to each of them and an  Officer's
Certificate will be presented to the Escrow Agent.


<PAGE>


      Section  IV.2  If no  such  agreement  can be  reached  after  good  faith
negotiation,  but in any event 30 days  after  Sellers  refuse to consent to the
delivery  of a portion of the Escrow Fund for the amount of a Loss in respect of
any Claim  made by Buyer (a  "Dispute"),  such  Dispute  shall be  submitted  to
mandatory  and binding  arbitration.  The  arbitration  shall be pursuant to the
Commercial  Arbitration  Rules  of the  American  Arbitration  Association  (the
"AAA").  The arbitration  hearing shall be held in such neutral  location as the
parties may mutually agree or, in the absence of mutual  agreement,  in New York
City.  The  arbitration  panel  will  have no  power  or  authority,  under  the
Commercial  Arbitration  Rules of the AAA or  otherwise,  to relieve the parties
from their  agreement  hereunder to arbitrate or otherwise to amend or disregard
any provision of this Agreement, including without limitation, the provisions of
this  Section 4.2. Any award  rendered by the  arbitration  panel will be final,
conclusive  and binding upon the parties and any judgment  hereon may be entered
and enforced in any court of competent jurisdiction.
      Section IV.3 If at any time there shall arise a dispute between any or all
of the Sellers  concerning  which of them shall be liable for payment of a Claim
or Claims, Sellers hereby expressly acknowledge and agree that: (i) such dispute
will not in any way whatsoever delay the delivery,  in the ordinary  course,  to
Buyer of any amount out of the Escrow Fund pursuant to Article III hereof;  (ii)
Sellers  shall  attempt in good faith to agree upon their rights with respect to
each such Claim;  (iii) if all Sellers so agree, a memorandum setting forth such
agreement  shall be prepared and signed by Sellers and shall be furnished to the
Escrow Agent and Buyer;  and (iv) if no such agreement can be reached after good
faith  negotiation,  but in any event 30 days after either,  as the case may be,
raises a dispute as  referenced  in this Section 4.3,  then the dispute shall be
submitted to binding  arbitration  before an arbitrator or arbitrators  mutually
agreed to by the Sellers.

                                   ARTICLE V
                          EXPIRATION OF ESCROW PERIOD
      If, upon  expiration  of the Escrow  Period,  Buyer shall have  asserted a
Claim and such Claim is pending or  unresolved  at the time of such  expiration,
the Escrow  Agent  shall  retain in the Escrow  Fund that  portion of the Escrow
Amount,  net of any  distributions  made or to be made  with  respect  to  other
Claims,  equal in value to the Loss  asserted in such Claim until such matter is
resolved.  If it is determined  that Buyer is entitled to recovery on account of
such Claim, the Escrow Agent shall deliver or cause to be delivered to Buyer the
Escrow Amount having a value equal to the amount due and payable with respect to
such Claim,  plus the interest  thereon net of taxes paid.  In the event that no
Claims,  or notices as  provided  in Article II, are made or are ending by or at
the end of the Escrow  Period,  the remaining  value of the Escrow Fund,  net of
expenses and taxes shall be disbursed to the Sellers as follows: William A.
Jackson (40%), Eugene A.
Cernan (30%) and W. T. Short (30%).
                                  ARTICLE VI
                      SCHEDULE FOR RELEASE OF ESCROW FUND
      If any  amount is paid by the  Escrow  Agent  pursuant  to a Claim and the
actual  Losses with respect to such Claim are at the time  determined to be less
than such payment,  Buyer shall promptly  return such excess to the Escrow Agent
to be  deposited  into the Escrow  Fund,  if this  Escrow  Agreement  is then in
effect, or to Sellers,  as the case may be, in accordance with the provisions of
this Article V, if this Escrow Agreement is no longer in effect.

                                 ARTICLE VIII
                  ESCROW AGENT'S RIGHTS AND RESPONSIBILITIES
      To induce the Escrow Agent to act hereunder, it is further agreed that:
            (a)   Any  recitals  contained in this Escrow  Agreement  shall be
      deemed to be those of the principals and not those of the Escrow Agent.
            (b)   The  Escrow  Agent  shall  not be under any duty to give the
      property held  hereunder any greater  degree of care than it gives its own
      similar property.
            (c) The Escrow Agent may engage legal counsel who may be counsel for
      any party to the Escrow  Agreement  and may act upon  advice of counsel in
      reference to any matter connected herewith and shall not be liable for any
      acts or  omissions  taken or  suffered  pursuant  to the  opinion  of such
      counsel.  The fees and  expenses of such  counsel  shall be deemed to be a
      proper  expense  for which the Escrow  Agent will have a lien  against the
      Escrow Fund.
            (d) The Escrow  Agent  shall not be liable in any respect on account
      of  the  identity,  authority  or  rights  of  the  parties  executing  or
      delivering or  purporting  to execute or deliver this Escrow  Agreement or
      any  documents  or papers  deposited or called for  hereunder.  The Escrow
      Agent shall be  protected  in acting upon any  notice,  request,  consent,
      certificate, order, affidavit, letter, telegram or other paper or document
      believed  by it to be genuine  and correct and to have been signed or sent
      by the proper person or persons.
            (e) The Escrow  Agent shall not be liable for the  outlawing  of any
      rights  under any  statute of  limitations  with  respect  to this  Escrow
      Agreement or any documents deposited with the Escrow Agent.


<PAGE>


            (f) The Escrow Agent is hereby expressly authorized to disregard any
      and all  warnings  given  by any of the  parties  hereto  or by any  other
      person,  excepting  only orders or process of courts of law, and is hereby
      expressly authorized to comply with and obey orders,  judgments or decrees
      of any court.  In case the Escrow  Agent obeys or  complies  with any such
      order,  judgment  or decree of any court,  the Escrow  Agent  shall not be
      liable to any of the  parties  hereto or to any other  person by reason of
      such compliance,  notwithstanding any such order, judgment or decree being
      subsequently reversed,  modified, annulled, set aside, vacated or found to
      have been entered without jurisdiction.
            (g)  The  Escrow  Agent  is   authorized  to  rely  on  the  written
      instructions of Sellers as being the acts,  respectively,  of Sellers, and
      the written instructions of the Chief Executive Officer or Chief Financial
      Officer of Buyer as being the act of Buyer.
            (h) The duties of the Escrow Agent shall be as expressed  under this
      Escrow Agreement,  and the Escrow Agent shall have no implied duties.  The
      permissive  right or power to take any action  shall not be construed as a
      duty to take action  under any  circumstances,  and the Escrow Agent shall
      not be  liable  except in the event of its  gross  negligence  or  willful
      misconduct.
            (i) The Escrow Agent shall not be called upon to advise any party as
      to its rights and obligations hereunder.


<PAGE>


            (j) In  consideration  of its  acceptance of the  appointment as the
      Escrow  Agent,  and except  with  respect to the Escrow  Agent's own gross
      negligence or willful  misconduct or acts or omissions by the Escrow Agent
      not in good faith, the other parties hereto agree,  jointly and severally,
      to  indemnify  and  hold  the  Escrow  Agent  harmless  as to any  loss or
      liability  incurred by it to any person,  firm or corporation by reason of
      its having  accepted the same or in carrying out any of the terms  hereof,
      and to  reimburse  the  Escrow  Agent  for  all  its  expenses,  including
      attorney's fees,  incurred by reason of its position  hereunder or actions
      taken pursuant hereto.  The Escrow Agent shall have no liability under, or
      duty to inquire into, the terms and  provisions of this Escrow  Agreement,
      and it is agreed that its duties are purely ministerial in nature and that
      the Escrow  Agent shall incur no liability  whatsoever  except for willful
      misconduct or gross negligence so long as it has acted in good faith. This
      paragraph (j) shall survive the termination of the Escrow Agreement.
            (k) The Escrow Agent may execute any of the duties under this Escrow
      Agreement by or through agents or receivers.
            (l) Unless  specifically  required  by this  Escrow  Agreement,  the
      Escrow Agent shall not be required to give any bond or surety or report to
      any court despite any statute, custom or rule to the contrary.
            (m) In the event the Escrow Agent becomes  involved in litigation by
      reason  hereof,  it is hereby  authorized to deposit with the clerk of the
      court in which the litigation is pending any and all funds,  securities or
      other  property held by it pursuant  hereto,  less its fees,  expenses and
      advances,  and thereupon  shall stand fully relieved and discharged of any
      further  duties  hereunder.  Also,  in  the  event  the  Escrow  Agent  is
      threatened  with litigation by reason hereof,  it is hereby  authorized to
      implead all interested parties in any court of competent  jurisdiction and
      to deposit  with the clerk of such  court any such  funds,  securities  or
      other  property held by it pursuant  hereto,  less its fees,  expenses and
      advances,  and thereupon  shall stand fully relieved and discharged of any
      further duties hereunder.


<PAGE>


            (n) The Escrow Agent shall not be obligated to risk its own funds in
      the  administration  of the Escrow Fund and shall have a lien  against any
      funds,  securities or other  property in its possession or control for its
      fees, expenses and advancements. The Escrow Agent need not take any action
      under  this  Escrow  Agreement  which may  involve  it in any  expense  or
      liability  until  indemnified  to its  satisfaction  for  any  expense  or
      liability it reasonably believes it may occur.
                                  ARTICLE IX

      The Escrow Agent shall  maintain a record of all Claims against the Escrow
Fund filed with it  pursuant to Article  III, a record of all such claims  which
shall  become  payable  as  provided  in  Article  III or IV and a record of all
payments from the Escrow Fund to Buyer.
                                   ARTICLE X
                          RESIGNATION OF ESCROW AGENT


<PAGE>


      The Escrow Agent,  or any successor,  may resign as Escrow Agent hereunder
by giving 30 days' written  notice thereof to Buyer and Sellers by registered or
certified mail. Such resignation  shall become effective  following such written
notice upon the earlier of the  appointment  by Buyer and Sellers of a successor
Escrow  Agent  that  accepts  the  appointment  and  agrees  to be  bound by the
provisions of this Agreement or the expiration of 30 days  thereafter.  Upon the
effectiveness of such  resignation,  all duties of the Escrow Agent so resigning
shall cease,  other than the duty to account in  accordance  with Article  VIII.
Buyer and  Sellers  shall have the right to  terminate  the  appointment  of the
Escrow Agent  hereunder by giving  written  notice  thereof to the Escrow Agent,
specifying the date upon which such  termination  shall take effect. A condition
precedent to such  termination  shall be the  designation of a successor  Escrow
Agent that has accepted the appointment and agreed to be bound by the provisions
of this  Agreement.  In event of such  termination,  the Escrow Agent shall turn
over and deliver to such  successor  Escrow Agent the Escrow Fund, and any other
sums and the records and instruments  held by it under this Escrow Agreement and
render the accounting required by Article VIII.
                                  ARTICLE XI

 FOR IMMEDIATE RELEASE

                   SPACEHAB Acquires Johnson Engineering Corp.
        Engineering services company nearly doubles SPACEHAB's revenue base

         Houston, Texas, July 1, 1998 - SPACEHAB, Inc., (Nasdaq: SPAB) announced
today  that it has  acquired  all of the  outstanding  capital  stock of Johnson
Engineering Corporation ("JE"), a 25-year-old Houston-based company. JE supports
the U.S. human space flight program by providing  engineering services to NASA's
Johnson Space Center.

         JE had more than $40  million  of  revenue  for its  fiscal  year ended
December  31,  1997,  and was  profitable.  JE will be a wholly  owned  SPACEHAB
subsidiary  and  will  retain  its name and  management.  Specific  terms of the
transaction, completed on July 1, were not disclosed.

         The merger  broadens  SPACEHAB's  core  business of  supporting  humans
living and  working in space.  With over 400  employees,  JE's  capabilities  to
perform  detailed design,  fabrication,  and operations  complements  SPACEHAB's
traditional strengths in conceptual design and program management.

         JE performs a number of critical  services for NASA including  managing
all  training  operations  and  facility  engineering  at the  Neutral  Buoyancy
Laboratory ("NBL"),  NASA's underwater facility where astronauts train for space
walks and assembly of the International Space Station (ISS); building mockups of
the ISS elements  used in NBL  training:  and  developing  hardware for the crew
living quarters currently scheduled for launch to the ISS in 2003.

         "SPACEHAB's goal is to become the leading company providing  commercial
space  products and services to government  and  industry,"  SPACEHAB  President
David A. Rossi  said.  "With JE, we now have many of the  critical  capabilities
that bring us another step closer to accomplishing that goal."

         Dr. Shelley  Harrison,  SPACEHAB's  Chairman and Chief  Executive
Officer,  added:  "The  combination of JE and SPACEHAB will expand SPACEHAB's
capability to support our most important customer: NASA."

         JE was a privately owned company until joining SPACEHAB on July 1. JE's
top three managers,  Tom Short, William Jackson and Eugene Cernan will remain in
key  management  positions.  Short will  continue as  President  and Cernan will
continue as Chairman of the JE subsidiary.  Jackson joins  SPACEHAB's  corporate
staff as a Vice President of Corporate Development.

         "We see this merger as an opportunity to continue and expand JE's space
flight support activities and to become more directly involved in the commercial
potential of space," Short said.

         Cernan, the last person to walk on the Moon, added:  "Having spent most
of my career in the space program, I am delighted to be part of SPACEHAB,  which
has been leading the  development  of commercial  systems that are advancing the
frontier of human space flight."

         SPACEHAB,  Inc., is the world's leading provider of commercial  payload
processing services for both astronaut-tended and unmanned payloads. SPACEHAB is
the first company to commercially  develop,  own and operate  habitable  modules
that provide space-based laboratory facilities and logistics resupply aboard the
U.S.  Space  Shuttles to support  people  living and working in space.  The next
SPACEHAB  flight is scheduled for Oct. 28,  aboard the Space  Shuttle  Discovery
when Senator John Glenn makes his return voyage to space.
