                               GENERAL INFORMATION


            This Proxy Statement is furnished in connection with the
solicitation by the Board of Directors (the "Board of Directors") of SPACEHAB,
Incorporated, a Washington corporation ("SPACEHAB" or the "Company"), of proxies
to be voted at the 1997 Annual Meeting of Stockholders on October 21, 1997 (the
"Annual Meeting"). This Proxy Statement, the accompanying proxy card and Annual
Report to Stockholders are first being mailed to stockholders on or about
September 22, 1997.

VOTING SECURITIES

            The Board of Directors has fixed the close of business on September
5, 1997 as the record date (the "Record Date") for the determination of
stockholders entitled to notice of, and to vote at, the Annual Meeting. As of
the Record Date, the Company had outstanding 11,146,237 shares of common stock,
no par value per share (the "Common Stock"). Holders of Common Stock are
entitled to notice of and to one vote per share of Common Stock owned as of the
Record Date at the Annual Meeting.

PROXIES
            Dr. Shelley A. Harrison and Margaret E. Grayson, the persons named
as proxies on the proxy card accompanying this Proxy Statement, were selected by
the Board of Directors of the Company to serve in such capacity. Dr. Harrison is
Chairman of the Board of Directors and Chief Executive Officer and Ms. Grayson
is Vice President of Finance, Chief Financial Officer and Treasurer. Each
stockholder giving a proxy has the power to revoke it at any time before the
shares it represents are voted. Revocation of a proxy is effective upon receipt
by the Secretary of the Company of either (i) an instrument revoking the proxy
or (ii) a duly executed proxy bearing a later date. Additionally, a stockholder
may change or revoke a previously executed proxy by voting in person at the
Annual Meeting.

VOTING OF PROXIES

            Since many SPACEHAB stockholders are unable to attend the Company's
Annual Meeting, the Board of Directors solicits proxies to give each stockholder
an opportunity to vote on all matters scheduled to come before the meeting and
set forth in this Proxy Statement. Stockholders are urged to read carefully the
material in this Proxy Statement, specify their choice on each matter by marking
the appropriate boxes on the enclosed proxy card, and sign, date and return the
card in the enclosed stamped envelope.

            If no choice is specified and the card is properly signed and
returned, the shares will be voted by the persons named as proxies in accordance
with the recommendations of the Board of Directors contained in this Proxy
Statement.

QUORUM; METHOD OF TABULATION

            The holders of at least one-third of the Common Stock issued and
outstanding and entitled to vote at the Annual Meeting, if represented in person
or by proxy, will constitute a quorum at the Annual 


                                        1
<PAGE>   5
Meeting. Under applicable law and the Company's Articles of Incorporation and
By-Laws, and assuming that a quorum is present, in the election of directors,
the persons elected will be the persons receiving the greatest number of votes,
up to the number of directors to be elected, of the stockholders present in
person or by proxy and entitled to vote thereon; provided that no stockholder
shall be allowed to cumulate his votes. At the Annual Meeting, the vote of a
majority in interest of the stockholders present in person or by proxy and
entitled to vote thereon is required to ratify the appointment of KPMG Peat
Marwick LLP as the independent public accountants of the Company's financial
statements for the fiscal year ending June 30, 1998.

            One or more inspectors of election appointed for the meeting will
tabulate the votes cast in person or by proxy at the Annual Meeting and will
determine whether or not a quorum is present. The inspectors of election will
treat abstentions as shares that are present and entitled to vote for purposes
of determining the presence of a quorum, but as unvoted for purposes of
determining the approval of any matter submitted to the stockholders for a vote.
If a broker indicates on a proxy that it does not have discretionary authority
as to certain shares to vote on a particular matter, those shares will not be
considered as present and entitled to vote with respect to that matter.

                       PROPOSAL 1 - ELECTION OF DIRECTORS

            A Board of 12 directors will be elected at the Annual Meeting. All
directors hold office until the next annual meeting of stockholders or until
their successors are duly elected and qualified. The Company's Articles of
Incorporation authorize the Board of Directors from time to time to determine
the number of its members. Vacancies in unexpired terms and any additional
positions created by board action may be filled by action of the existing Board
of Directors.

            The nominees for whom the enclosed proxy is intended to be voted are
set forth below. It is contemplated that all nominees will be available for
election, but if one or more is not, the proxy will be voted in accordance with
the best judgment of the proxyholder for such person or persons as may be
designated by the Board of Directors unless the stockholder has directed
otherwise.

            The Audit Committee recommended and the Board of Directors approved
the appointment of KPMG Peat Marwick LLP as independent public accountants for
fiscal 1998, subject to stockholder ratification. The Audit Committee, in
arriving at its recommendation to the Board, reviewed the performance of KPMG
Peat Marwick LLP in prior years as well as the firm's reputation for integrity
and competence in the fields of accounting and auditing. The Audit Committee has
expressed its satisfaction with KPMG Peat Marwick LLP in these respects.

            KPMG Peat Marwick LLP has served as the Company's independent
auditor since 1985. Representatives of KPMG Peat Marwick LLP are expected to be
present at the Annual Meeting and will have the opportunity to make such
statements as they may desire. They are also expected to be available to respond
to appropriate questions from the stockholders present.

            THE BOARD OF DIRECTORS RECOMMENDS A VOTE FOR THE RATIFICATION OF
THE APPOINTMENT OF KPMG PEAT MARWICK LLP AS INDEPENDENT PUBLIC ACCOUNTANTS OF
THE COMPANY FOR THE FISCAL YEAR ENDING JUNE 30, 1998.


           PROPOSAL 3 - APPROVAL OF AMENDMENT TO STOCK INCENTIVE PLAN

            At the January 29, 1997 meeting of the Board of Directors, the Board
of Directors approved three categories of amendments to the Company's 1994 Stock
Incentive Plan (the "Stock Incentive Plan"), subject to stockholder approval at
the Annual Meeting. The first such amendment would increase the maximum number
of shares of Common Stock reserved for issuance under the Stock Incentive Plan
from 1,250,000 to 2,750,000. The Board of Directors approved this amendment to
increase the number of shares subject to the Stock Incentive Plan in order to
allow it to continue to provide long-term incentives to 


                                        6
<PAGE>   10
employees and consultants of the Company. The second category of amendments is
intended to conform the terms of the Stock Incentive Plan to recent changes made
to Rule 16b-3 under the Securities Exchange Act of 1934 ("Rule 16b-3"). Among
other technical changes, the Rule 16b-3 amendments would change the provisions
of the Stock Incentive Plan relating to plan administration to allow for
administration by members of the Board of Directors who satisfy the definition
of "non-employee director" under new Rule 16b-3. The third category of
amendments is intended to satisfy certain conditions of Section 162(m) ("Section
162(m)") of the United States Internal Revenue Code of 1986, as amended (the
"Tax Code"), which limits the amount of tax deductible compensation that may be
paid to individual executive officers of publicly held companies to $1 million
per year. The Section 162(m) amendments would allow the Company to preserve the
tax deductibility of stock options granted to the Company's executive officers
by complying with the requirements for exemption under Section 162(m). Among
other technical amendments, the Section 162(m) amendments would (i) impose a
limitation of 200,000 on the number of shares underlying stock options that may
be granted under the Stock Incentive Plan to any one participant during any one
calendar year and (ii) allow administration of the Stock Incentive Plan by
members of the Board of Directors who satisfy the definition of "outside
director" under Section 162(m).

            During fiscal 1997, the Company retained an independent compensation
consultant to evaluate its compensation practices. In addition, during fiscal
1997, management of the Company conducted an evaluation of the continued
appropriateness of the Stock Incentive Plan relative to the Company's growth in
recent years. At the time the Stock Incentive Plan was originally adopted, the
Company had 6 employees. As of June 30, 1997, the Company and its subsidiary had
61 employees. Management noted the increase in the personnel employed by the
Company and its subsidiary and the potential that the Company might consider
acquisitions of other businesses, in which case the ability to make additional
option grants would be desirable. Therefore, management determined that an
increase of 1,500,000 new shares under the Stock Incentive Plan would be needed.
In addition, in April 1997, the Company determined that an aggregate of
1,150,405 options to purchase shares of Common Stock previously granted did not
continue to represent effective long-term incentives as the exercise prices at
which such options were granted were above the then current share price of the
Common Stock. As a result, the Company granted an aggregate of 815,300 options,
which utilized the existing shares remaining under the Stock Incentive Plan. An
additional 644,256 options already outstanding were canceled and returned to the
Stock Incentive Plan to be made available for the April 1997 grants. As a
result, no shares are currently available for grant under the Stock Incentive
Plan.

            The primary features of the Stock Incentive Plan are summarized
below. The summary is qualified by, and subject to, the full text of the Stock
Incentive Plan, as proposed to be amended and restated, a copy of which is
attached as Exhibit A and should be referred to for a complete statement of the
terms of the Stock Incentive Plan.

                                  PLAN SUMMARY

Administration and Operation of the Plan

            The Compensation Committee of the Board of Directors or such other
appropriate committee of directors as the Board of Directors shall designate
(the "Committee") has all powers with respect to the administration of the Stock
Incentive Plan, including without limitation, selecting which persons will
receive awards and the extent of the award, determining the terms and conditions
of the award, and resolving all questions arising under the Stock Incentive
Plan. Under the Stock Incentive Plan, stock options, stock appreciation rights,
restricted stock and performance share awards may be granted by the Committee
for the purpose of attracting and motivating key employees and consultants of
the Company and to provide long-term incentive compensation to the Company's
employees. The Stock Incentive Plan permits the extension of loans by the
Company to a participant in connection with the payment of the exercise price of
options, the purchase price of restricted shares or the tax incurred with
respect to any award. Furthermore, the Committee may provide for a payment in
the form of cash or shares of Common Stock to offset a participant's tax
incurred with respect to the receipt of an award and any such tax offset
payment. All awards under the Stock Incentive Plan become immediately
exercisable and fully vested upon a "change of control" of the Company (as
defined therein).


                                        7
<PAGE>   11
Eligibility

            Officers and other key employees and consultants of the Company (or
its subsidiaries) are eligible to be granted awards under the Stock Incentive
Plan. Participants under the Stock Incentive Plan are selected from time to time
by the Committee from among those eligible employees.

Number of Shares Available

            The maximum number of shares initially reserved for issuance under
the Stock Incentive Plan was 1,250,000 shares. As of June 30, 1997, options to
purchase 1,250,000 shares of Common Stock pursuant to the Stock Incentive Plan
were issued and outstanding. Since the inception of the Stock Incentive Plan,
the Committee has not granted any stock appreciation rights, restricted stock
awards or performance share awards, nor has it made any loans or tax offset
payments. Providing that the proposed amendment to the Stock Incentive Plan is
approved by stockholders, the aggregate number of shares of Common Stock
reserved for issuance upon exercise of options granted under the Stock Incentive
Plan will be increased to and shall not exceed 2,750,000 shares.

            If any shares of Common Stock that are the subject of an award are
not issued for any reason, such shares shall no longer be charged against the
maximum share limitation and may again be made subject to awards under the Stock
Incentive Plan. In the event of certain corporate reorganizations,
recapitalizations, or other specified transactions affecting the Company or the
Common Stock, the Committee may make appropriate adjustments to the number of
shares available for grant and to the number of shares and prices under
outstanding awards made before the event.

Stock Options

            The Stock Incentive Plan authorizes the grant of non-qualified stock
options to employees and consultants of the Company and its subsidiaries.
Incentive stock options may only be granted to employees of the Company and its
subsidiaries. The exercise price of a non-qualified stock option may be
determined by the Committee in its discretion. The exercise price of an
incentive stock option may not be less than the fair market value of the Common
Stock on the date of grant. The value of Common Stock (determined at the time of
grant) that may be subject to incentive stock options that become exercisable by
any one employee in any one year is limited by the Tax Code to $100,000. The
term of stock options granted under the Stock Incentive Plan shall be fixed by
the Committee, except that the maximum term for incentive stock options is 10
years from the date of grant. The Committee shall determine the extent to which
an option shall become and/or remain exercisable in the event of the termination
of employment or service of a participant under certain circumstances, including
retirement, death or disability, subject to certain limitations for incentive
stock options. Under the Stock Incentive Plan, the exercise price of an option
is payable by the participant in cash or, in the discretion of the Committee, in
Common Stock or through the extension of a loan by the Company or a combination
thereof, or through any other means approved by the Committee.

Stock Appreciation Rights

            The Committee may award stock appreciation rights to participants
under the Stock Incentive Plan. A stock appreciation right entitles the holder,
upon exercise, to a payment based on the difference between the base price
assigned to the stock appreciation right by the Committee on the date of grant
and the fair market value of the Company's Common Stock on the date of exercise.
A stock appreciation right shall be in the form and have the terms and
conditions as specified by the Committee. In the event of a "change of control"
(as defined in the Stock Incentive Plan), the Committee may limit the exercise
of stock appreciation rights to within the 60-day period following the
occurrence of the change of control and may also provide that the amount to be
paid upon exercise of a stock appreciation right shall be based on the "change
of control price" determined pursuant to the Stock Incentive Plan.


                                        8
<PAGE>   12
Restricted Stock

            The Committee may award shares of Common Stock to participants under
the Stock Incentive Plan, subject to such restrictions on transfer and
conditions of forfeiture as it deems appropriate. Such conditions may include
requirements as to the continued service of the participant with the Company or
a subsidiary, the attainment of specified performance goals or such other
criteria as may be determined by the Committee. Subject to the transfer
restrictions and forfeiture restrictions relating to the restricted stock award,
the participant shall have such rights of a stockholder of the Company, which
may include voting and dividend rights, as the Committee may provide. The
Committee may waive, in whole or in part, any or all of the conditions to
receipt of, or restrictions with respect to, any or all of a participant's
restricted stock.

Performance Share Awards

            The Committee may grant performance share awards under the Stock
Incentive Plan. Performance share awards are payable in shares of Common Stock
upon the attainment of specified performance goals or such other criteria as the
Committee may determine. At the time of grant, the Committee establishes the
number of performance shares to be awarded to any employee and the duration of
the performance period. At the end of the performance period, the employee
receives the number of shares of Common Stock covered by the performance share
award, cash equal to the fair market value of such Common Stock, or a
combination of shares and cash, as the Committee may determine. Except as may be
provided by the Committee, in the event of an employee's termination of
employment before the end of the performance period, such employee's performance
share award shall be forfeited. The Committee may waive, in whole or in part,
any or all of the conditions to receipt of, or restrictions with respect to,
stock or cash under a performance share award.

Termination of Employment

            If a participant's employment with the Company or a subsidiary
terminates by reason of death, disability, retirement, voluntary or involuntary
termination or otherwise, such participant's option grants shall be exercisable
to the extent determined by the Committee.

Amendment or Termination of the Plan

            The Board of Directors may discontinue the Stock Incentive Plan at
any time and may amend it from time to time. No amendment or discontinuation of
the Stock Incentive Plan shall adversely affect any award previously granted
without the employee's written consent. Amendments may be made without
stockholder approval except as required to satisfy applicable regulatory
requirements.

Fiscal 1997 Option Grants

            An aggregate of 1,027,350 stock options were granted during fiscal
1997 to Company employees. During fiscal 1997, each of the Named Executive
Officers received the number of stock options set forth following his or her
name: Dr. Shelley A. Harrison (322,700); Chester M. Lee (186,865); David A.
Rossi (82,863); John M. Lounge (74,116); and Margaret E. Grayson (65,000). See
"Executive Compensation - Option Grants in Fiscal 1997." As of September 10,
1997, the closing price of a share of Common Stock on the Nasdaq National Market
was $10.50 per share.

Basic Federal Tax Consequences

            The following is a general description of the current federal income
tax consequences to participants and the Company relating to options and other
awards that may be granted under the Stock Incentive Plan. This discussion does
not purport to cover all tax consequences relating to options or other awards.


                                        9
<PAGE>   13
            The grant of a stock option under the Stock Incentive Plan will not
generally result in taxable income for the participant, nor in a deductible
compensation expense for the Company, at the time of grant. The participant will
have no taxable income upon exercising an incentive stock option (except that
the alternative minimum tax may apply), and the Company will receive no
deduction when an incentive stock option is exercised. Upon exercising a
non-qualified option, the participant will recognize ordinary income in the
amount by which the fair market value of the Common Stock on the date of
exercise exceeds the exercise price, and the Company will generally be entitled
to a corresponding tax deduction. The treatment of a participant's disposition
of shares of Common Stock acquired upon the exercise of an option is dependent
upon the length of time the shares have been held and on whether such shares
were acquired by exercising an incentive stock option or a non-qualified option.
Generally , there will be no tax consequence to the Company in connection with
the disposition of shares acquired under an option, except that the Company may
be entitled to a deduction in the case of a disposition of shares acquired upon
exercise of an incentive stock option before the applicable incentive stock
option holding period has been satisfied.

            The current federal income tax consequences of other awards
authorized under the Stock Incentive Plan generally follow certain basic
patterns: stock appreciation rights are subjected to income tax upon exercise in
substantially the same manner as non-qualified stock options; restricted stock
subject to a substantial risk of forfeiture results in income recognition equal
to the excess of the fair market value of the stock over the purchase price (if
any) only at the time the restrictions lapse, unless the recipient elects to
accelerate recognition as of the date of grant; and performance shares generally
are subject to tax at the time of payment. In each of the foregoing cases, the
Company generally has a corresponding tax deduction at the time the participant
recognizes taxable income.

            Approval of the amendment of the Stock Incentive Plan requires the
affirmative vote of the majority of the Company's shares present, or
represented, and entitled to vote. Continuation of the Stock Incentive Plan, as
amended and restated to reflect the foregoing amendments, will be subject to the
approval of the stockholders of this Proposal 3.

            THE BOARD OF DIRECTORS RECOMMENDS THAT THE STOCKHOLDERS VOTE FOR THE
APPROVAL OF THE AMENDMENTS TO THE STOCK INCENTIVE PLAN.


           PROPOSAL 4 - APPROVAL OF 1997 EMPLOYEE STOCK PURCHASE PLAN

            The Board of Directors, at its meeting held on January 29, 1997,
approved the 1997 Employee Stock Purchase Plan (the "Stock Purchase Plan"), upon
the recommendation of the Compensation Committee. The Stock Purchase Plan, which
will become effective as of October 1, 1997, is being presented for stockholder
approval to enable the Stock Purchase Plan to qualify under Section 423 of the
Tax Code. The purpose of the Stock Purchase Plan is to enhance stockholder value
and promote the attainment of significant business objectives of the Company by
allowing employees to purchase the Company's Common Stock at a discount of 15%,
thereby giving employees an interest in common with that of the stockholders.

            The primary features of the Stock Purchase Plan are summarized
below. The summary is qualified by, and subject to, the full text of the Stock
Purchase Plan, a copy of which is attached as Exhibit C and should be referred
to for a complete statement of the terms of the Stock Purchase Plan.

                                  PLAN SUMMARY

Administration and Operation of the Plan

            The Stock Purchase Plan shall be administered by the Compensation
Committee of the Board of Directors or such other committee of directors as the
Board of Directors shall designate (the "Committee"). The Committee has
discretionary authority to interpret the Stock Purchase Plan and to determine
all questions arising in the administration, application and operation of the
Stock Purchase Plan. The Committee 


                                       10
<PAGE>   14
determines the compensation and benefits of all officers of the Company and
establishes general policies relating to compensation and benefits of employees
of the Company.

            Each employee eligible to participate in the Stock Purchase Plan
will be granted an option to contribute from one and ten percent of the
employee's compensation towards the purchase of the Company's Common Stock at a
purchase price for each calendar quarter (a "Plan Quarter") equal to the lower
of (x) 85% of the fair market value of a share of the Company's Common Stock on
the first day of the Plan Quarter and (y) 85% of the fair market value of a
share of the Company's Common Stock on the last day of the Plan Quarter. Fair
market value is defined in the Stock Purchase Plan as the closing price of the
Company's Common Stock on the relevant date. The amount to be contributed by a
participant will be deducted from each paycheck, held for the participant during
a Plan Quarter and applied towards the purchase of the Company's Common Stock on
the last day of the Plan Quarter. Unless otherwise determined by the Committee,
amounts held for a participant during a Plan Quarter will not bear interest. A
participant may change the percentage of his or her compensation to be
contributed for any given Plan Quarter at least 15 days prior to the beginning
of that period and may elect not to participate with respect to one or more plan
periods.

            The Company will bear the costs of administration of the Stock
Purchase Plan, including any fees, costs and expenses relating to the purchase
of shares. The employee will be responsible for all fees, costs and expenses due
upon the sale of any shares purchased under the Stock Purchase Plan.

            No employee will have the right to purchase stock under the Stock
Purchase Plan if (a) immediately after acquiring the right to purchase stock the
employee would own five percent (5%) or more of the total combined voting power
or value of all classes of stock of the Company or any subsidiary (taking into
account all stock the ownership of which would be attributable to the employee
under applicable provisions of the Tax Code), (b) such right would permit the
employee's right to purchase stock under the Stock Purchase Plan and any other
stock purchase plans of the Company and its subsidiaries in effect from time to
time to exceed $25,000 of fair market value of such stock (determined as of the
first day of each Plan Quarter) for each calendar year, or (c) which would
permit such employee the right to purchase more than 10,000 shares (or such
other number of shares as may be determined in advance for any Plan Quarter by
the Committee) of Common Stock in any Plan Quarter.

Eligibility

            Any employee of the Company or any subsidiary designated by the
Committee who customarily works at least 20 hours per week and more than five
months per year is eligible to participate in the Stock Purchase Plan.
Approximately 61 employees currently are eligible to participate in the Stock
Purchase Plan. Non-employee directors of the Company are not eligible to
participate in the Stock Purchase Plan.

Number of Shares Available

            The number of shares available for purchase under the Stock Purchase
Plan is 1,500,000. Such shares will be newly issued shares reserved for issuance
under the Stock Purchase Plan, treasury shares, shares purchased on the open
market, or any combination thereof. Shares purchased for a participant will be
held for the participant unless a participant requests that a certificate be
issued for such shares. The participant will have the right to vote and be
entitled to dividends, if any, on shares held for the participant's account. Any
cash dividends paid with respect to shares held for the account of a participant
shall be, as determined by the Committee on a uniform basis as to all
participants, either (i) distributed to the participant or (ii) credited to the
participant's account and used, in the same manner as payroll deductions, to
purchase additional shares under the Stock Purchase Plan on the last day of the
Plan Quarter.


                                       11
<PAGE>   15
Termination of Employment

            Upon a participant's termination of employment for any reason (other
than death, retirement or permanent disability) all contributions to the
participant's account will cease, such participant shall cease to be a
participant as of the date of such termination of employment, and, as soon as
practicable, the participant will receive the cash balance remaining in the
participant's account and a certificate or certificates evidencing the stock
purchased by the participant. If a participant shall retire, become permanently
disabled or die, contributions to the participant's account will cease and the
participant or the participant's representative may elect to withdraw the
remaining cash balance or, in the event that no election to withdraw has been
made, the remaining cash balance shall be applied to the purchase of stock on
the last day of the Plan Quarter.

Amendment or Termination of the Stock Purchase Plan

            The Company may, at any time, by action of the Board of Directors,
amend, suspend or discontinue the Stock Purchase Plan, in whole or in part.

Basic Federal Tax Consequences

            The following is a general description of the current federal income
tax consequences to participants and the Company relating to the grant of
options to purchase and purchases of stock under the Stock Purchase Plan. This
discussion does not purport to cover all tax consequences relating to the Stock
Purchase Plan.

            No federal income tax will be recognized by the participant upon the
grant of the option to purchase stock or upon the purchase of the stock under
the Stock Purchase Plan. If a participant disposes of stock purchased under the
Stock Purchase Plan within two years from the first day of the Plan Quarter
during which such stock was purchased, at the time of disposition the
participant will recognize (a) ordinary income equal to the fair market value of
the stock on the day it was purchased less the amount paid for the shares, and
(b) a capital gain or loss equal to the difference between the participant's
basis in the stock (the amount paid for the stock plus the amount taxed as
ordinary income under subparagraph (a) above) and the amount realized upon the
disposition of the stock. If the participant holds the stock for more than one
year, the capital gain or loss will be a long-term capital gain or loss. The
Company generally will be entitled to a deduction in the amount of the ordinary
income on which the participant is taxed under subparagraph (a) above. A
participant must notify the Company if the participant disposes of any stock
purchased under the Stock Purchase Plan within two years from the first day of
the Plan Quarter during which such stock was purchased.

            If a participant disposes of stock purchased under the Stock
Purchase Plan more than two years from the first day of the Plan Quarter during
which such stock was purchased, at the time of the disposition the participant
will recognize ordinary income equal to the lesser of (x) the excess of the fair
market value of the stock on the date of disposition over the amount paid for
such stock, and (y) 15% of the fair market value of such stock at the beginning
of the Plan Quarter in which the stock was purchased. In addition, the
participant will recognize a long-term capital gain or loss equal to the
difference between the participant's basis in the stock (the amount paid for the
stock plus the amount taxed as ordinary income under subparagraph (x) above) and
the amount realized upon the disposition of the stock. The Company will not be
entitled to any deduction.

New Plan Benefits

            It is not possible at this time to determine the dollar value of
benefits available under the Stock Purchase Plan. The table below sets forth the
aggregate of the dollar values of the excess of the fair market values of the
stock on the last day of each Plan Quarter over the dollar amount of stock that
would have been purchased during the period from July 1, 1996 through June 30,
1997 (the four most recent 


                                       12
<PAGE>   16
calendar quarters) by the Named Executive Officers (as defined hereinafter), all
current executive officers as a group (the "Executive Group"), all current
directors who are not executive officers as a group (the "Non-Executive Director
Group") and all employees, including all current officers who are not executive
officers, as a group (the "Employee Group") if the Stock Purchase Plan had been
in effect during such period and each had elected to participate to the maximum
extent permissible of ten percent of his or her salary.

(1)   Assuming that each employee had contributed the maximum of 10% of his or
      her base pay up to the maximum of $25,000 during the period from July 1,
      1996, though June 30, 1997, the table reflects the dollar value
      (calculated as described below) of the shares that would have been
      purchased had the Stock Purchase Plan been in effect for all of such
      period. The dollar value has been calculated by adding for each Plan
      Quarter the amount obtained by multiplying (x) the number of shares that
      would have been purchased in such Plan Quarter by (y) (i) the fair market
      value of the stock on the last day of such Plan Quarter, minus (ii) the
      price the employee would have paid for the stock purchased on that day.

(2)   Non-employee directors are not eligible to participate in the Stock
      Purchase Plan.

(3)   It is not possible to calculate the dollar value for the Employee Group.

            Approval of the Stock Purchase Plan requires the affirmative vote of
a majority of the Company's shares present, or represented, and entitled to
vote. If the stockholders do not approve the Stock Purchase Plan, the Stock
Purchase Plan will not go into effect and the Board of Directors will consider
whether to adopt some alternative arrangement based on its assessment of the
needs of the Company.

            THE BOARD OF DIRECTORS RECOMMENDS THAT THE STOCKHOLDERS VOTE FOR THE
APPROVAL OF THE 1997 EMPLOYEE STOCK PURCHASE PLAN.



             PROPOSAL 5 - APPROVAL OF AMENDMENTS TO DIRECTORS' PLAN

            In November 1995, the Company adopted a directors' stock option plan
(the "Directors' Plan"), as a means for non-employee members of the Board of
Directors to acquire an equity interest in the Company and to secure for the
Company and its stockholders the benefits inherent in such equity ownership by
persons whose advice and counsel are important to the continued growth and
success of the Company.

            At the August 20, 1997 meeting of the Executive Committee of the
Board of Directors, the 


                                       13
<PAGE>   17
following amendments to the Directors' Plan were approved, subject to approval
by the stockholders pursuant to this Proxy Statement: (i) the aggregate number
of shares of Common Stock with respect to which options may be issued under the
Directors' Plan shall be increased to 500,000, (ii) each participant under the
Directors' Plan shall be granted an option to purchase 10,000 shares of Common
Stock on the date on which such person first becomes a director and (iii) a
one-time grant of an option to purchase 10,000 shares of Common Stock shall be
made to each incumbent non-employee director.

            The Company believes that the successful establishment of corporate
strategies and objectives is enhanced by the contributions, guidance and
experience of persons who serve on the Board of Directors as outside directors.
Therefore, the ability to attract and retain such persons is in the best
interest of the Company and its stockholders. During fiscal 1997, the Company
retained an independent compensation consultant to evaluate its compensation
practices. The Board of Directors believes that the proposed amendments to the
Directors' Plan, including the establishment of an initial option grant along
with a one-time make-up grant for incumbent outside directors, is consistent
with prevailing practices in the Company's industry relating to the
compensation of outside directors.                        

            The primary features of the Directors' Plan are summarized below.
The summary is qualified by, and subject to, the full text of the Directors'
Plan, as proposed to be amended and restated, a copy of which is attached as
Exhibit B and should be referred to for a complete statement of the terms of the
Directors' Plan.

                                  PLAN SUMMARY

Administration and Operation of the Plan

            The authority to manage and control the operation and administration
of the Directors' Plan is vested in a committee consisting of two or more
members of the Board of Directors, although such committee cannot direct the
number, timing or price of options granted to eligible recipients thereunder.

            Non-employee directors of the Company are eligible to participate in
the Directors' Plan. Under the current Directors' Plan, effective as of the date
of each annual meeting of stockholders, each non-employee director of the
Company who is elected or continues as a member of the Board of Directors of the
Company shall be awarded an option to purchase 5,000 shares of Common Stock. The
aggregate number of shares of Common Stock with respect to which options may be
issued under the Directors' Plan is 250,000. If the proposed amendments to the
Directors' Plan are adopted, (i) the aggregate number of shares of Common Stock
with respect to which options may be issued under the Director's Plan shall be
increased to 500,000, (ii) each participant under the Directors' Plan shall be
granted an option to purchase 10,000 shares of Common Stock on the date on which
such person first becomes a director and (iii) a one-time grant of an option to
purchase 10,000 shares of Common Stock shall be made to each incumbent
non-employee director.

            Each option grant under the Directors' Plan vests after the first
anniversary of the date of grant and expires six years thereafter. The number of
shares of Common Stock related to awards that expire unexercised or are
forfeited, surrendered, terminated or canceled are available for future awards
under the Directors' Plan. If a director's service on the Board of Directors
terminates for any reason other than death, all vested options may be
exercisable by such director until the earlier of his or her death or the
expiration date of the option grant. In the event of a director's death, any
options which such director was entitled to exercise on the date immediately
preceding his or her death may be exercised by a transferee of such director for
the six-month period after the date of the director's death.

Number of Shares Available

            The maximum number of shares initially reserved for issuance under
the Directors' Plan was 250,000 shares. As of August 31, 1997, the Company had
granted 50,000 options under the Directors' Plan.


                                       14
<PAGE>   18
Amendment or Termination of the Plan

            Subject to any approval of the stockholders of the Company which may
be required by law, the Board of Directors of the Company may at any time amend,
suspend or terminate the Directors' Plan. No amendment or suspension of the
Directors' Plan shall alter or impair any option previously granted under the
Directors' Plan without the consent of the holder thereof.

Fiscal 1997 Option Grants

            An aggregate of 50,000 stock options were granted pursuant to the
Director's Plan during fiscal 1997 to non-employee directors of the Company.
During fiscal 1997, each of the Company's non-employee directors received the
number of stock options set forth following his name:  Hironori Aihara
(5,000); Robert A. Citron (5,000); Dr. Edward E. David, Jr. (5,000); Dr. Shi
H. Huang (5,000); Gordon S. Macklin (5,000); Dr. Brad M. Meslin (5,000); Dr.
Udo Pollvogt (5,000); Alvin L. Reeser (5,000); James R. Thompson (5,000) and
Prof. Ernesto Vallerani (5,000).  As of September 10, 1997, the closing price
of a share of Common Stock on the Nasdaq National Market was $10.50  per
share.

Basic Federal Tax Consequences

            The following is a general description of the current federal income
tax consequences to participants and the Company relating to options granted
under the Directors' Plan. This discussion does not purport to cover all tax
consequences relating to options or other awards.

            The grant of a stock option under the Directors' Plan will not
generally result in taxable income for the participant, nor in a deductible
compensation expense for the Company, at the time of grant. Upon exercising an
option, the participant will recognize ordinary income in the amount by which
the fair market value of the Common Stock on the date of exercise exceeds the
exercise price, and the Company will generally be entitled to a corresponding
tax deduction. The treatment of a participant's disposition of shares of Common
Stock acquired upon the exercise of an option is dependent upon the length of
time the shares have been held. There will be no tax consequence to the Company
in connection with the disposition of shares acquired under an option.

            Approval of the amendment of the Directors' Plan requires the
affirmative vote of the majority of the Company's shares present, or
represented, and entitled to vote. Continuation of the Directors' Plan, as
amended and restated to reflect the foregoing amendments, will be subject to the
approval of the stockholders of this Proposal 5.

            THE BOARD OF DIRECTORS RECOMMENDS THAT THE STOCKHOLDERS VOTE FOR THE
APPROVAL OF THE AMENDMENTS TO THE DIRECTORS' PLAN.

COMPENSATION COMMITTEE REPORT ON EXECUTIVE COMPENSATION

            Compensation of the Company's executives is subject to review and
approval by the Compensation Committee (the "Compensation Committee") of the
Company's Board of Directors.  The Compensation Committee consists of two
outside directors, James R. Thompson (Chairman) and Dr. Edward E. David, Jr.,
and the Chairman and Chief Executive Officer of the Company, Dr. Shelley A.
Harrison.

Compensation Philosophy.

            In determining executive compensation policies, the Compensation
Committee has four primary objectives:

            (1)   to attract, motivate and retain key executive talent;


                                       22
<PAGE>   26
            (2)   to balance the flexibility to reward individuals' skills with
                  the need to structure compensation for defined roles;

            (3)   to ensure that executive compensation is competitive with that
                  of other leading companies in related fields; and

            (4)   to provide incentives to achieve corporate objectives, thereby
                  contributing to the overall goal of enhancing stockholder
                  value.

            The Compensation Committee's compensation policies discussed below
are designed to achieve the foregoing objectives. The Compensation Committee
expects to continuously review and refine the Company's compensation practices
as necessary to respond to a changing business environment.

            In order to evaluate and establish appropriate compensation
practices, the Company consults multiple sources of information. The
Compensation Committee uses data from benchmark companies within the aerospace
or similar high technology industries to assess the Company's performance and
compensation operations, product lines, revenues and markets served. The
Compensation Committee seeks to set its executive compensation levels
competitively with the benchmark companies, to the extent such targets are
consistent with the Compensation Committee's objectives. During fiscal 1997, the
Company retained an independent compensation consultant to evaluate its
compensation practices, and, in particular, salary and bonus levels. The Company
utilized the recommendations of the compensation consultant's report in setting
incentive bonus and option grant levels at the end of fiscal year 1997.

Elements of Executive Compensation.

            The Company's executive compensation program has three components:
(1) annual cash compensation in the form of base salary and incentive bonus
payments, (2) long-term incentive compensation in the form of stock options
granted under the Company's Stock Incentive Plan and (3) other compensation and
employee benefits generally available to all employees of the Company, such as
health insurance. Annual cash compensation is primarily designed to reward
current performance. Long-term incentives and other compensation and employee
benefits are primarily designed to create performance incentives over the long
term for executive officers and employees.

            Base Salary. The base salary of each executive officer is set at a
level deemed sufficient to attract and retain qualified executive officers. The
Compensation Committee has generally determined target base salaries according
to the average base salaries paid by benchmark high technology companies.
Aggregate base salary increases are intended to maintain compensation levels
that are in line with leading companies in related fields, while individual base
salary increases are set to reflect individual performance levels. The base
salaries of certain executive officers are subject to minimums set forth in
individual employment agreements.

            Incentive Bonuses. Annual cash bonuses are designed to provide
incentives based on individual contribution to the achievement of the Company's
annual business goals. Bonus payments have generally been reflective of the
Company's performance in achieving revenues, profitability and other operating
and corporate objectives, as well as the scope of an executive officer's
responsibilities. The Compensation Committee makes a determination as to
incentive bonus payments at the end of each year based on a subjective valuation
of the contributions of individual executive officers to the achievement of the
Company's annual business goals. The award of annual incentive bonuses is based
on achieving corporate goals and the amount of individual incentive bonus
payments is determined by percentage ranges established annually by the
Compensation Committee.

            Long-Term Incentives. The grant of stock options is the Company's
current method for providing long-term incentive compensation to its employees.
The Compensation Committee believes that the use of stock options attracts and
retains qualified personnel for positions of substantial responsibility and also
serves to motivate its executive officers to promote the success of the
Company's business and maximize 


                                       23
<PAGE>   27
stockholder value.

            During fiscal 1997, management of the Company conducted an
evaluation of the continued appropriateness of the Stock Incentive Plan relative
to the Company's growth in recent years. At the time the Stock Option Plan was
adopted, the Company had 6 employees. As of June 30, 1997, the Company and its
subsidiary had 61 employees. Management noted the increase in the personnel
employed by the Company and its subsidiary and the potential that the Company
might consider acquisitions of other businesses, in which case the ability to
make additional option grants would be desirable. Therefore, management
determined that an increase of 1,500,000 new shares under the Stock Incentive
Plan would be needed. In addition, in April 1997, the Company determined that an
aggregate of 1,150,405 options to purchase shares of Common Stock previously
granted did not continue to represent effective long-term incentives as the
exercise prices at which such options were granted were above the current share
price of the Common Stock. As a result, the Company granted an aggregate of
815,300 options, which utilized the existing shares remaining under the Stock
Incentive Plan and an additional 644,256 options already outstanding were
canceled and returned to the Stock Incentive Plan to be made available for the
April 1997 grants. At the January 29, 1997 meeting of the Board of Directors, an
amendment to increase the number of shares reserved for issuance under the Stock
Incentive Plan was approved, subject to approval by the stockholders pursuant to
this Proxy Statement.

Compensation of Chief Executive Officer.

            The Compensation Committee based the fiscal year 1997 Chief
Executive Officer ("CEO") compensation on the policies described above.

            Dr. Shelley A. Harrison served as Chairman and CEO of the Company
throughout the fiscal year.  During fiscal 1997, Dr. Harrison received a
total of $380,982 for his services.  Dr. Harrison's compensation level for
fiscal 1997 was deemed by the Compensation Committee to be appropriate given
Dr. Harrison's qualifications and contribution to meeting the Company's
objectives.

Tax Deductibility of Executive Compensation.

            Section 162(m) of the Tax Code disallows corporate deductibility for
certain compensation paid in excess of $1 million to the Company's Chief
Executive Officer and to each of the four other most highly paid executive
officers of publicly-held companies. "Performance-based compensation," as
defined in Section 162(m), is not subject to the deductibility limitation
provided certain stockholder approval and other requirements are met. The
Company believes that the stock options granted in fiscal 1997 and prior years
satisfied the requirements of federal tax law and thus compensation recognized
in connection with such awards should be fully deductible. It is the Company's
intention to maximize the deductibility of compensation paid to its officers, to
the extent consistent with the best interests of the Company. During fiscal
1997, the Company did not exceed the $1 million deductibility cap with respect
to any officer covered by Section 162(m).

                                    COMPENSATION COMMITTEE,



                                    James R. Thompson, Chairman
                                    Dr. Edward E. David, Jr.

                                  OTHER MATTERS

            The Board of Directors of the Company knows of no matters to be
presented at the Annual Meeting other than those described in this Proxy
Statement. In the event that other business properly comes before the meeting,
the persons named as proxies will have discretionary authority to vote the
shares represented by the accompanying proxy in accordance with their own
judgment.

PROXY SOLICITATION EXPENSE

            The cost of the solicitation of proxies will be borne by the
Company. In addition to solicitation by mail, directors, officers and employees
of the Company, without receiving any additional compensation, may solicit
proxies personally or by telephone or facsimile. The Company has retained
American Stock Transfer & Trust Company to request brokerage houses, banks and
other custodians or nominees holding stock in their names for others to forward
proxy materials to their customers or principals who are the beneficial owners
of shares and will reimburse them for their expenses in doing so. The Company
does not anticipate that the costs and expenses incurred in connection with this
proxy solicitation will exceed those normally expended for a proxy solicitation
for those matters to be voted on in the Annual Meeting.

COMPLIANCE WITH SECTION 16(a) OF THE SECURITIES EXCHANGE ACT OF 1934

            Section 16(a) of the Securities Exchange Act of 1934 requires the
Company's directors and executive officers and persons who beneficially own more
than 10% of the Company's Common Stock to file reports of ownership and changes
in ownership with the Securities and Exchange Commission (the "SEC"). Such
directors, executive officers and greater than 10% stockholders are required by
SEC regulation to furnish to the Company copies of all Section 16(a) forms they
file.

            The Company believes that during fiscal year 1997, all Section 16(a)
filing requirements were satisfied on a timely basis, except the number of late
reports noted for the following individuals: Robert Citron (1-covering 1
transaction); Dr. Edward E. David, Jr. (3-covering 3 transactions); William S.
Dawson (2-covering 2 transactions); Margaret E. Grayson (3-covering 3
transactions); Dr. Shelley A. Harrison (4-covering 4 transactions); Dr. Shi
Huang (1-covering 1 transaction); Chester M. Lee (4-covering 4 transactions);
John M. Lounge (3-covering 3 transactions); Gordon S. Macklin (2-covering 3
transactions); Dr. Brad M. Meslin (2-covering 3 transactions); Dr. Udo Pollvogt
(1-covering 1 transaction); Alvin L. Reeser (2-covering 2 transactions); David
A. Rossi (4-covering 4 transactions); M. Dale Steffey (2-covering 2
transactions); James R. Thompson (1-covering 1 transaction); and Prof. Ernesto
Vallerani (1-covering 1 transaction).

            The Company believes that the late filings noted above were
inadvertent. It has, nonetheless, designated one of its employees to assist the
Company's directors and executive officers with the preparation and filing of
their periodic reports under Section 16(a).

DEADLINE FOR SUBMISSION OF STOCKHOLDER
PROPOSALS FOR NEXT YEAR'S ANNUAL MEETING

            The proxy rules adopted by the SEC provide that certain stockholder
proposals must be included in the proxy statement for the Company's Annual
Meeting. For a proposal to be considered for inclusion in the Company's proxy
materials for the Company's 1998 Annual Meeting of Stockholders, it must be
received in writing by the Company on or before May 26, 1998 at its principal
office, 1595 Spring Hill Road, Suite 360, Vienna, Virginia 22182, Attention:
Secretary.

                            1994 STOCK INCENTIVE PLAN
              (AS AMENDED AND RESTATED EFFECTIVE OCTOBER 21, 1997)


SECTION 1.    PURPOSE

              The purpose of the SPACEHAB, Incorporated 1994 Stock Incentive
Plan (the "Plan") is to enable SPACEHAB, Incorporated (the "Company") and its
subsidiaries (as defined below) to provide a select group of employees the
opportunity to acquire a proprietary interest in the company and to benefit from
the appreciation in the value of its common shares and thereby to enhance the
ability of the company to attract and retain employees of exceptional ability
who, by their participation in the Plan, will have a greater incentive to
contribute to the company's long-term success and growth. For purposes of the
Plan, a "subsidiary" means any subsidiary corporation as defined in Section
424(f) of the Internal Revenue Code of 1986, as amended (the "Code").

SECTION 2.    TYPES OF AWARDS

            2.1 Award under the Plan may be in the form of (i) incentive stock
options or non-qualified stock options ("Stock Options"); (ii) Stock
Appreciation Rights; (iii) Restricted Stock; (iv) Performance Shares; (v) Loans;
and/or (vi) Tax Offset Payments.

            2.2 An eligible employee may be granted one or more types of awards,
which may be independent or granted in tandem. If two awards are granted in
tandem the employee may exercise (or otherwise receive the benefit of) one award
only to the extent he or she relinquishes the tandem award.

SECTION 3.    ADMINISTRATION

            3.1 The Plan shall be administered by the Compensation Committee of
the Company's Board of Directors (the "Board") or such other committee of
directors as the Board shall designate (the "Committee"), which shall consist of
two or more directors who are "non-employee directors" within the meaning of
Rule 16b-3 ("Rule 16b-3") promulgated under the Securities Exchange Act of 1934,
as amended (the "Act"), and who are "outside directors" within the meaning of
Section 162(m) of the Code.

            3.2 The Committee shall have the authority to grant awards to
eligible employees under the Plan; to adopt, alter and repeal such
administrative rules, guidelines and practices governing the Plan as it shall
deem advisable; to interpret the terms and provisions of the Plan and any award
granted under the Plan; and to otherwise supervise the administration of the
Plan. In particular, and without limiting its authority and powers, the
Committee shall have the authority:

                  (a) to determine whether and to what extent any award or
combination of awards will be granted hereunder, including whether any awards
will be granted in tandem with each other;

                  (b) to select the employees to whom awards will be granted;

                  (c) to determine the number of shares of the common stock of
the Company (the "Stock") to be covered by each award granted hereunder;

                  (d) to determine the terms and conditions of any award granted
hereunder, including, but not limited to, any vesting or other restrictions
based on performance and such other factors as the Committee may determine, and
to determine whether the terms and conditions of the award are satisfied;

                  (e) to determine the treatment of awards upon an employee's
retirement, disability, death, termination for cause or other termination of
employment;


                                       A-2
<PAGE>   33
                  (f) to determine pursuant to a formula or otherwise the fair
market value of the Stock on a given date; provided, however, that if the
Committee fails to make such a determination, fair market value shall, in the
event the Stock is traded on a national exchange, mean the closing sale price of
the Stock on a given date;

                  (g) to determine whether the amount of any dividends declared
with respect to the number of shares covered by an award (i) will be paid to the
employee currently or (ii) will be deferred and deemed to be reinvested or (iii)
will otherwise be credited to the employee, or that the employee has no rights
with respect to such dividends;

                  (h) to determine whether to what extent, and under what
circumstances Stock and other amounts payable with respect to an award will be
deferred either automatically or at the election of an employee, including
providing for and determining the amount (if any) of deemed earnings on any
deferred amount during any deferral period;

                  (i) to provide that the shares of Stock received as a result
of an award shall be subject to a right of first refusal, pursuant to which the
employee shall be required to offer to the Company any shares that the employee
wishes to sell, subject to such terms and conditions as the Committee may
specify;

                  (j) to amend the terms of any award, prospectively or
retroactively; provided, however, that no amendment shall impair the rights of
the award holder without his or her consent;

                  (k) to substitute new Stock Options for previously granted
Stock Options, or for options granted under other plans, in each case including
previously granted options having higher option prices; and

                  (l) to allow an option holder to exercise his or her option
prior to its expiration and pay for the acquired shares with currently owned
shares, while at the same time receiving replacement options, at the then
current market price, for the same remaining term as the option exercised.

            3.3 All determinations made by the Committee pursuant to the
provisions of the Plan shall be final and binding on all persons, including the
Company and Plan participants.

            3.4 The Committee may from time to time delegate to one or more
officers of the Company any or all of its authority granted hereunder except
with respect to awards granted to persons subject to Section 16 of the Act. The
Committee shall specify the maximum number of shares that the officer or
officers to whom such authority is delegated may award.

SECTION 4.  STOCK SUBJECT TO PLAN

            4.1 The total number of shares of Stock reserved and available for
distribution under the Plan shall be 2,750,000 (subject to further adjustment as
provided below). Such shares may consist of authorized but unissued shares or
treasury shares. The exercise of a Stock Appreciation Right for cash, the
payment of any other award in cash shall not count against this share limit.

            4.2 To the extent an option terminates without having been
exercised, or an award terminates without the employee having received payment
of the award, or shares awarded are forfeited, the shares subject to such award
shall again be available for distribution in connection with future awards under
the Plan. At no time will the number of shares issued under the Plan plus the
number of shares covered by outstanding awards under the Plan exceed the number
of shares authorized under the Plan.

            4.3 In the event of any merger, reorganization, consolidation, sale
of substantially all 


                                       A-3
<PAGE>   34
assets, recapitalization, Stock dividend, Stock split, spin-off, split-up,
split-off, distribution of assets or other change in corporation structure
affecting the Stock, a substitution or adjustment, as may be determined to be
appropriate by the Committee in its sole discretion, shall be made in the
aggregate number of shares reserved for issuance under the Plan, the number of
shares subject to outstanding awards and the amounts to be paid by employees or
the Company, as the case may be, with respect to outstanding awards.

            4.4 The number of shares of Stock underlying Stock Options or
free-standing Stock Appreciation Rights that may be granted under the Plan to
any one participant during any one calendar year shall not exceed 200,000
shares, subject to adjustment in the same manner as provided in subsection 4.3
above. To the extent required for exemption under Section 162(m) of the Code,
any Stock Options or Stock Appreciation Rights that are canceled or repriced
shall not again be available for grant under this maximum share limit.

SECTION 5.  ELIGIBILITY

            Officers and other key employees and consultants of the Company or a
subsidiary are eligible to be granted awards under the Plan. A director of the
Company or a subsidiary who is not also an employee of the Company or a
subsidiary will not be eligible to be granted awards under the Plan. The
participants under the Plan shall be selected from time to time by the
Committee, in its sole discretion, from among those eligible employees.

SECTION 6.  STOCK OPTIONS

            6.1 The Stock Options awarded under the Plan may be of two types:
(i) Incentive Stock Options within the meaning of Section 422 of the Code or any
successor provision thereto; and (ii) Non-Qualified Stock Options. To the extent
that any Stock Option does not qualify as an Incentive Stock Option, it shall
constitute a Non-Qualified Stock Option.

            6.2 Subject to the following provisions, Stock Options awarded under
the Plan shall be in such form and shall have such terms and conditions as the
Committee may determine:

                  (a) Option Price. The option price per share of Stock
purchasable under a Stock Option shall be determined by the Committee; provided,
however, that any Stock Option granted under the Plan that is intended to
satisfy the requirements of Section 162(m) of the Code shall have an option
price of not less than 100% of the fair market value of the Stock subject to the
option on the date the Stock Option is granted.

                  (b) Option Term. The term of each Stock Option shall be fixed
by the Committee.

                  (c) Exercisability. Stock Options shall be exercisable at such
time or times and subject to such terms and conditions as shall be determined by
the Committee. If the Committee provides that any Stock Option is exercisable
only in installments, the Committee may waive such installment exercise
provisions at any time in whole or in part.

                  (d) Method of Exercise. Stock Options may be exercised in
whole or in part at any time during the option period by giving written notice
of exercise to the Company specifying the number of shares to be purchased,
accompanied by payment of the purchase price. Payment of the purchase price
shall be made in such manner as the Committee may provide in the award, which
may include cash (including cash equivalents), delivery of shares of Stock
already owned by the optionee or subject to awards hereunder, through the
delivery of irrevocable instructions to a broker to deliver promptly to the
Company an amount equal to the purchase price, or by any other manner permitted
by law and determined by the Committee, or any combination of the foregoing. The
Committee may provide that all or part of the shares received upon the exercise
of a Stock Option which are paid for using Restricted Stock or Performance
Shares 


                                       A-4
<PAGE>   35
shall be restricted or deferred in accordance with the original terms of the
award in question. The Committee shall determine acceptable methods for
providing notice of exercise for tendering shares of Stock and for delivery of
irrevocable instructions to a broker and may impose such limitations and
prohibitions on the use of Stock or irrevocable instructions to a broker to
exercise as it deems appropriate.

                  (e) No Shareholder Rights. An optionee shall have neither
rights to dividends or other rights of a shareholder with respect to shares
subject to a Stock Option until the optionee has given written notice of
exercise and has paid for such shares.

                  (f) Surrender Rights. The Committee may provide that options
may be surrendered for cash upon any terms and conditions set by the Committee.

                  (g) Non-transferability. No Stock Option shall be transferable
by the optionee other than by will or by the laws of descent and distribution.
During the optionee's lifetime, all Stock Options shall be exercisable only by
the optionee.

                  (h) Termination of Employment. If an optionee's employment
with the Company or a subsidiary terminates by reason of death, disability,
retirement, voluntary or involuntary termination or otherwise, the Stock Option
shall be exercisable to the extent determined by the Committee. The Committee
may provide that, notwithstanding the option term fixed pursuant to Section
6.2(b), a Stock Option which is outstanding on the date of an optionee's death
shall remain outstanding for an additional period after the date of such death.

            6.3 Notwithstanding the provisions of Section 6.2, no Incentive
Stock Option shall (i) have an option price which is less than 100% of the fair
market value of the Stock on the date of the award of the Stock Option, (ii) be
exercisable more than ten years after the date such Incentive Stock Option is
awarded or (iii) be awarded more than ten years after the effective date of the
Plan. No Incentive Stock Option shall be granted to an employee who, at the time
the option is granted, owns stock possessing more than 10% of the total combined
voting power of all classes of stock of the Company or of its subsidiary, unless
the option price, at the time of the award, is at least 110% of the fair market
value of the stock subject to the option and such option is not exercisable
after the expiration of five years from the date of the award.

SECTION 7.  STOCK APPRECIATION RIGHTS

            7.1 A Stock Appreciation Right shall entitle the holder thereof to
receive payment of an amount, in cash, shares of Stock or a combination thereof,
as determined by the Committee, equal in value to the excess of the fair market
value of the shares as to which the award is granted on the date of exercise
over an amount specified by the Committee. Any such award shall be in such form
and shall have such terms and conditions as the Committee may determine.

            7.2 The Committee may provide that a Stock Appreciation Right may be
exercised only within the 60-day period following occurrence of a Change of
Control (as defined in Section 15.2). The Committee may also provide that in the
event of a Change of Control the amount to be paid upon the exercise of a Stock
Appreciation Right shall be based on the Change of Control Price (as defined in
Section 15.3).

SECTION 8.  RESTRICTED STOCK

            Subject to the following provisions, all awards of Restricted Stock
shall be in such form and shall have such terms and conditions as the Committee
may determine:

            (a) The Restricted Stock award shall specify the number of shares of
Restricted Stock to be awarded, the price, if any, to be paid by the recipient
of the Restricted Stock and the date or dates on which, or the conditions upon
the satisfaction of which, the Restricted Stock will vest. The vesting of


                                       A-5
<PAGE>   36
Restricted Stock may be conditioned upon the completion of a specified period of
service with the Company or a subsidiary, upon the attainment of specified
performance goals or upon such other criteria as the Committee may determine.

            (b) Stock certificates representing the Restricted Stock awarded to
an employee shall be registered in the employee's name, but the Committee may
direct that such certificates shall be held by the Company on behalf of the
employee. Except as may be permitted by the Committee, no share of Restricted
Stock may be sold, transferred, assigned, pledged or otherwise encumbered by the
employee until such share has vested in accordance with the terms of the
Restricted Stock award. At the time Restricted Stock vests, a certificate for
such vested shares shall be delivered to the employee (or his or her designated
beneficiary in the event of death), free of all restrictions.

            (c) The Committee may provide that the employee shall have the right
to vote or receive dividends on Restricted Stock. The Committee may provide that
Stock received as a dividend on, or in connection with a stock split of
Restricted Stock, shall be subject to the same restrictions as the Restricted
Stock.

            (d) Except as may be provided by the Committee, in the event of an
employee's termination of employment before all of his or her Restricted Stock
has vested, or in the event any conditions to the vesting of Restricted Stock
have not been satisfied prior to any deadline for the satisfaction of such
conditions set forth in the award, the shares of Restricted Stock which have not
vested shall be forfeited, and the Committee may provide that (i) any purchase
price paid by the employee shall be returned to the employee or (ii) a cash
payment equal to the Restricted Stock's fair market value on the date of
forfeiture, if lower, shall be paid to the employee.

            (e) The Committee may waive, in whole or in part, any or all of the
conditions to receipt of, or restrictions with respect to, any or all of the
employee's Restricted Stock.

SECTION 9.  PERFORMANCE SHARE AWARDS

            Subject to the following provisions, all awards of Performance
Shares shall be in such form and shall have such terms and conditions as the
Committee may determine:

            (a) The Performance Shares award shall specify the number of
Performance Shares to be awarded to any employee and the duration of the period
(the "Performance Period") after which, and the terms pursuant to which, the
Performance Shares will be issued to the employee. The Committee may condition
the award of Performance Shares, or receipt of Stock or cash at the end of the
Performance Period, upon the attainment of specified performance goals or such
other criteria as the Committee may determine.

            (b) Except as may be permitted by the Committee, Performance Share
awards may not be sold, assigned, transferred, pledged or otherwise encumbered
during the Performance Period.

            (c) At the expiration of the Performance Period, the employee (or
his or her designated beneficiary in the event of death) shall receive (i)
certificates for the number of shares of Stock equal to the number of shares
covered by the Performance Share award, (ii) cash equal to the fair market value
of such Stock or (iii) a combination of shares and cash, as the Committee may
determine.

            (d) Except as may be provided by the Committee, in the event of an
employee's termination of employment before the end of the Performance Period,

SECTION 10. LOANS

            The Committee may provide that the Company shall make, or arrange
for, a loan or loans to an employee with respect to the exercise of any Stock
Option awarded under the Plan, with respect to the payment of the purchase
price, if any, of the Restricted Stock awarded hereunder, or with respect to any
taxes arising from an award hereunder; provided, however, that the Company shall
not loan to an employee more than the excess of the purchase or exercise price
of an award (together with the amount of any taxes arising from such award) over
the par value of any shares of Stock awarded. The Committee shall have full
authority to decide whether a loan will be made hereunder and to determine the
amount, term and provisions of any such loan, including the interest rate to be
charged, whether the loan will be with or without recourse against the borrower,
any security for the loan, the terms on which the loan is to be repaid and the
conditions, if any, under which the loan may be forgiven.

SECTION 11. TAX OFFSET PAYMENTS

            The Committee may provide for a Tax Offset Payment by the Company to
the employee in an amount specified by the Committee, which shall not exceed the
amount necessary to pay the federal, state, local and other taxes payable with
respect to any award and receipt of the Tax Offset Payment, assuming the
employee is taxed at the maximum tax rate applicable to such income. The Tax
Offset Payment may be paid in cash, Stock or a combination thereof, as
determined by the Committee.

SECTION 12. ELECTION TO DEFER AWARDS

            The Committee may permit an employee to elect to defer receipt of an
award for a specified period or until a specified event, upon such terms as are
determined by the Committee.

SECTION 13. TAX WITHHOLDING

            13.1 Each employee shall, no later than the date as of which the
value of an award first becomes includible in the employee's gross income for
applicable tax purposes, pay to the Company, or make arrangements satisfactory
to the Committee regarding payment of, any federal, state, local or other taxes
of any kind required by law to be withheld with respect to the award. The
obligations of the Company under the Plan shall be conditional on such payment
or arrangements, and the Company (and, where applicable, any subsidiary), shall,
to the extent permitted by law, have the right to deduct any such taxes from any
payment of any kind otherwise due to the employee.

            13.2 To the extent permitted by the Committee, and subject to such
terms and conditions as the Committee may provide, an employee may irrevocably
elect to have the withholding tax obligation, or any additional tax obligation
with respect to any awards hereunder, satisfied by (i) having the Company
withhold shares of Stock otherwise deliverable to the employee with respect to
the award or (ii) delivering to the Company, shares of unrestricted Stock.

SECTION 14. AMENDMENTS AND TERMINATION

            The Board may discontinue the Plan at any time and may amend it from
time to time. Solely to the extent deemed necessary or advisable by the Board,
for purposes of complying with Section 422 of the Code, Section 162(m) of the
Code or the rules of any securities exchange or for any other reason, the Board
may seek the approval of any such amendment by the Company's shareholders.
Notwithstanding the foregoing, no termination or amendment of the Plan shall in
any manner affect any award theretofore granted without the holder's consent.

SECTION 15. CHANGE OF CONTROL

            15.1 In the event of a Change of Control, unless otherwise
determined by the Committee at the time of grant or by amendment (with the
holder's consent) of such grant:

                  (a) all outstanding Stock Options and all outstanding Stock
Appreciation Rights awarded under the Plan shall become fully exercisable and
vested;

                  (b) the restrictions and deferral limitations applicable to
any outstanding Restricted Stock and Deferred Stock awards under the Plan shall
lapse and such shares and awards shall be deemed fully vested; and

                  (c) to the extent the cash payment of any award is based on
the fair market value of Stock, such fair market value shall be the Change of
Control Price.

            15.2   A "Change of Control" shall be deemed to occur on:

                  (a) The date that any person or group deemed a person under
Sections 3(a)(9) and 13(d)(3) of the Act, other than the Company and its
subsidiaries as determined immediately prior to that date, in a transaction or
series of transactions has become the beneficial owner, directly or indirectly
(with beneficial ownership determined as provided in Rule 13d-3, or any
successor rule, under such Act) of 20% or more of the outstanding securities of
the Company having the right under ordinary circumstances to vote at an election
of the Board;

                  (b) the date on which one-third or more of the members of the
Board shall consist of persons other than Current Directors (for these purposes,
a "Current Director" shall mean any member of the Board as of the effective date
of the Plan and any successor of a Current Director whose nomination or election
has been approved by a majority of the Current Directors then on the Board); or

                  (c) the date of approval by the shareholders of the Company of
an agreement providing for (A) the merger or consolidation of the Company with
another corporation where the shareholders of the Company, immediately prior to
the merger or consolidation, would not beneficially own, immediately after the
merger or consolidation, shares entitling such shareholders to 50% or more of
all votes (without consideration of the rights of any class of stock to elect
directors by a separate class vote) to which all shareholders of the corporation
issuing cash or securities in the merger or consolidation would be entitled in
the election of directors or where the members of the Board, immediately prior
to the merger or consolidation, would not, immediately after the merger or
consolidation, constitute a majority of the Board of Directors of the
corporation issuing cash or securities in the merger or consolidation or (B) the
sale or other disposition of all or substantially all the assets of the Company.

            15.3 "Change of Control Price" means the highest price per share
paid for the Company's Stock in any transaction reported on any national stock
exchange or in the over-the-counter market, or paid or offered in any
transaction related to a Change of Control at any time during the 90-day period
ending with the Change of Control. Notwithstanding the foregoing sentence, in
the case of Stock Appreciation Rights granted in tandem with Incentive Stock
Options, the Change of Control Price shall be the highest price paid on the date
on which the Stock Appreciation Right is exercised.

SECTION 16. GENERAL PROVISIONS

            16.1 Each award under the Plan shall be subject to the requirement
that, if at any time the Committee shall determine that (i) the listing,
registration or qualification of the Stock subject to the award or related
thereto upon any securities exchange or under any state or federal law, or (ii)
the consent or approval of any government regulatory body or (iii) an agreement
by the recipient of an award with respect to the disposition of Stock, is
necessary or desirable (in connection with any requirement or interpretation of

federal or state securities law, rule or regulation) as a condition of, or in
connection with, the granting of such award or the issuance, purchase or
delivery of Stock thereunder, such award shall not be granted or exercised, in
whole or in part, unless such listing, registration, qualification, consent,
approval or agreement shall have been effected or obtained free of any
conditions not acceptable to the Committee.

            16.2 Nothing set forth in this Plan shall prevent the Board from
adopting other or additional compensation arrangements. Neither the adoption of
the Plan nor any award hereunder shall confer upon any employee of the Company,
or of a subsidiary, any right to continued employment.

            16.3 Determinations by the Committee under the Plan relating to the
form, amount and terms and conditions of awards need not be uniform, and may be
made selectively among persons who receive or are eligible to receive awards
under the Plan, whether or not such persons are similarly situated.

            16.4 No member of the Board or the Committee, nor any officer or
employee of the Company acting on behalf of the Board or the Committee, shall be
personally liable for any action, determination or interpretation taken or made
with respect to the Plan, and all members of the Board or the Committee and all
officers or employees of the Company acting on their behalf shall, to the extent
permitted by law, be fully indemnified and protected by the Company in respect
of any such action, determination or interpretation.

                        1995 DIRECTORS' STOCK OPTION PLAN
              (as amended and restated effective October 21, 1997)


SECTION 1.  PURPOSE

            The 1995 Directors' Stock Option Plan (the "Plan") of SPACEHAB,
Incorporated (the "Company"), is intended to advance the best interest of the
Company by providing the nonemployee members of the Board of Directors of the
Company an opportunity to purchase shares of common stock of the Company (the
"Shares"). This Plan is effective as of September 7, 1995 (the "Effective Date")
and is not intended to qualify as an incentive stock option plan under section
422 of the Internal Revenue Code of 1986, as amended (the "Code").

SECTION 2.  ADMINISTRATION

            The authority to manage and control the operation and administration
of the Plan shall be vested in a Committee (the "Committee") consisting of 2 or
more members of the Board of Directors of the Company, who shall be appointed
by, and may be removed by, such Board; provided that the Committee shall have no
authority, power, or discretion to determine the number, timing or price of
options granted pursuant to paragraph 3 or to alter the terms and conditions of
options as set forth herein. In the absence of any such appointment or removal,
the Board of Directors shall act as the Committee under the Plan. Any
interpretation of the Plan by the Committee and any decision made by the
Committee on any other matter within its discretion is final and binding on all
persons.

SECTION 3.  PARTICIPATION

            Each member of the Company's Board of Directors who is not an
employee of the Company shall be a "Participant" in the Plan. Each Participant
shall receive on October 21, 1997 a one-time grant of an option to purchase
10,000 Shares and each person who becomes a Participant on or after October 21,
1997 shall receive a one-time grant of an option to purchase 10,000 shares on
the date he or she becomes a Participant. In addition, effective as of the date
of each annual meeting of the Company's stockholders on or after the Effective
Date, each Participant who is elected or continues as a member of the Board of
Directors of the Company shall be awarded an option to purchase 5,000 Shares.

SECTION 4.  SHARES SUBJECT TO THE PLAN

            The aggregate number of Shares with respect to which options may be
issued under the Plan is 500,000. The number of shares related to awards that
expire unexercised or are forfeited, surrendered, terminated or canceled shall
again be available for additional awards under the Plan unless the Plan shall
have terminated. Any Shares issued under the Plan may be treasury shares or
authorized but unissued shares.

SECTION 5.  OPTION PRICE

            The option price with respect to each Share shall be the Fair Market
Value of a Share on the date the award is made. The "Fair Market Value" of a
Share as of any date shall be equal to the closing sale price of a Share as
reported on the exchange on which it is traded or as reported by an applicable
automated quotation system on the applicable date or, if no sales of Shares are
reported on such date, the closing sale price of a Share on the date the Shares
were last reported on the exchange or automated quotation system. If the Shares
are not listed or admitted to trading on any exchange or quotation system, Fair
Market Value shall be determined in good faith by the Committee. The purchase
price may be subject to adjustment in the event there is any change in the
capitalization of the Company as provided in paragraph 12.


                                       B-2
<PAGE>   42
SECTION 6.  OPTION EXPIRATION DATE

            The "Expiration Date" with respect to an option or any portion
thereof granted to a Participant under the Plan means the date which is six
years after the date on which the option is first exercisable. Subject to
paragraph 8, all rights to purchase Shares pursuant to an option shall cease no
later than the option's Expiration Date.

SECTION 7.  EXERCISE OF OPTIONS

            Each option shall be exercisable, either in whole or in part, at any
time after the first anniversary of the grant date and before the option's
Expiration Date. A Participant may exercise an option by giving written notice
thereof prior to the option's Expiration Date to the Chief Executive Officer of
the Company at the Company's corporate headquarters setting out the number of
Shares with respect to which the option is to be exercised. Contemporaneously
with the delivery of such notice, the full purchase price of the Shares
purchased pursuant to the exercise of a stock option together with any required
state or federal withholding taxes shall be paid in the form of: (a) cash,
certified check, bank draft, or postal or express money order payable to the
order of the Company or (b) Common Stock at the fair market value on the date of
exercise, and specifying the address to which the certificates for the Shares
are to be mailed. As promptly as practicable after receipt of written
notification and payment, the Company shall deliver to the Participant
certificates in the Participant's name for the number of Shares with respect to
which the option has been exercised. Delivery shall be deemed effected when a
stock transfer agent of the Company shall have deposited the certificates in the
United States mail, addressed to the Participant, at the address specified under
this paragraph.

SECTION 8.  TERMINATION OF SERVICE

            If the Participant terminates service on the Board of Directors
before the first anniversary of the date that an option is granted, such option
shall expire upon the Participant's termination of service and shall not be
exercisable by any person. If the Participant's service on the Board of
Directors terminates for any reason other than death, any options which are not
canceled in accordance with the preceding sentence shall by exercisable by the
Participant until the earlier of his death or the option's Expiration Date. In
the event of the death of a Participant, any options which the Participant was
entitled to exercise on the date immediately preceding his death shall be
exercisable by the person or persons to whom that right passes by will or by the
laws of descent and distribution for a period of six months after the date of
death, but no later than the option's Expiration Date.

SECTION 9.  COMPLIANCE WITH APPLICABLE LAWS

            Notwithstanding any other provision in the Plan, the Company shall
have no liability to issue any Shares under the Plan unless such issuance would
comply with all applicable laws and applicable requirements of any securities
exchange or similar entity. Prior to the issuance of any Shares under the Plan,
the Company may require a written statement that the recipient is acquiring the
Shares for investment and not for the intention of distributing the Shares.
Certificates representing such Shares may bear a legend referring to such
restrictions.

SECTION 10. TRANSFERABILITY

            Options under the Plan are not transferable except (i) by will or by
the laws of descent and distribution or (ii) by the Participant, to his or her
employer or firm. Options may be exercised during the lifetime of the
Participant only by the Participant, and after the death of the Participant,
only as provided in paragraph 8.


                                       B-3
<PAGE>   43
SECTION 11. STOCKHOLDER STATUS

The grant of an option under the Plan shall not confer upon the holder thereof
any right as a stockholder of the Company. No person entitled to exercise any
option granted under the Plan shall have any of the rights or privileges of a
stockholder of record with respect to any Shares issuable upon exercise of such
option until certificates representing such Shares have been issued and
delivered.

SECTION 12. ADJUSTMENTS TO NUMBER OF SHARES SUBJECT TO THE PLAN AND TO OPTION
            TERMS

            Subject to the following provisions of this paragraph 12, in the
event of any change in the outstanding Shares by reason of any stock dividend,
stock split, recapitalization, merger, consolidation, combination, exchange of
shares or other similar corporate change, an appropriate and proportionate
adjustment shall be made in the number and kind of Shares subject to options
outstanding or to be granted under the Plan. Any such adjustment in any
outstanding option shall be made without change in the aggregate purchase price
applicable to the unexercised portion of such option but with a corresponding
adjustment in the price for each Share covered by such option as well as the
adjustment in the number and kind of Shares mentioned above. In no event shall
the purchase price for a Share be adjusted below the par value of such Share,
nor shall any fraction of a Share be issued upon the exercise of an option.

SECTION 13. AGREEMENT WITH COMPANY

            At the time of a grant of an option, the Committee may require a
Participant to enter into an agreement with the Company in a form specified by
the Committee agreeing to the terms and conditions of the Plan.

SECTION 14. AMENDMENT AND TERMINATION OF PLAN

            Subject to any approval of the stockholders of the Company which may
be required by law, the Board of Directors of the Company may at any time amend,
suspend or terminate the Plan. No amendment, suspension or termination of the
Plan shall alter or impair any option previously granted under the Plan without
the consent of the holder thereof.

payroll date occurring immediately after the Commencement Date of a Plan
Quarter. No interest shall accrue to Participants on any amounts withheld under
the Plan, unless and until the Committee shall approve such accrual of interest
on terms that it shall specify and apply on a uniform basis as to all
Participants.

            (c) The Participant's Contribution Rate, once established, shall
remain in effect for all Plan Quarters unless changed by the Participant in
writing delivered to such Participant's Sponsoring Employer and filed with such
Sponsoring Employer at least 15 days prior to the Commencement Date of the next
Plan Quarter. A Participant's Contribution Rate for a Plan Quarter may not be
increased, decreased or otherwise modified at any time during the 15-day period
prior to the Commencement Date of such Plan Quarter.

            (d) A Participant may notify his or her Sponsoring Employer of such
Participant's desire to discontinue his or her Participant Contributions by
delivering to his or her Sponsoring Employer written notice on such forms as may
be provided by the Company or such Participant's Sponsoring Employer at least 15
days prior to the Purchase Date of the relevant Plan Quarter. Upon such request,
there shall be promptly refunded to such Participant as soon as practicable the
entire cash balance in his or her Contribution Account. If a Participant
determines to discontinue his or her Participant Contributions pursuant to this
Section 3.05(d), (i) such Participant shall be terminated from the Plan
effective upon the date of receipt of such Participant's notice to his or her
Sponsoring Employer and (ii) such Participant shall not be permitted to be a
Participant in the Plan for the remainder of the calendar year of the Company in
which such notice is received. In the event that a Participant's payroll
deductions are prevented by legal process, the Participant will be deemed to
have


                                       C-4

terminated from the Plan.

            (e) By enrolling in the Plan, each Participant will be deemed to
have authorized the establishment of a brokerage account in his or her name at a
securities brokerage firm or other financial institution, if approved by the
Committee in its discretion.

            3.04 TERMINATION OF EMPLOYMENT. Any Participant (i) whose employment
by a Sponsoring Employer is terminated for any reason (except death, retirement
or Permanent Disability) or (ii) who shall cease to be an Employee under the
Plan, in either case during a Plan Quarter, shall cease being a Participant as
of the date of such termination of employment. Upon such termination of
employment, there shall be refunded to such Participant as soon as practicable
the entire cash balance in such Participant's Contribution Account. Section
4.03(b) hereof shall apply to the issuance of certificates to a Participant
following termination of employment.

            3.05  DEATH, RETIREMENT OR PERMANENT DISABILITY

            (a) If a Participant shall die during a Plan Quarter, no further
Participant Contributions on behalf of the deceased Participant shall be made.
The executor or administrator of the deceased Participant's estate may elect to
withdraw the balance in said Participant's Contribution Account by notifying the
deceased Participant's Sponsoring Employer in writing at least 15 days prior to
the Purchase Date in respect of such Plan Quarter. In the event no election to
withdraw has been made, the balance accumulated in the deceased Participant's
Contribution Account shall be used to purchase shares of Common Stock in
accordance with Article IV hereof.

             (b) If, during a Plan Quarter, a Participant shall (i) retire or
(ii) incur a Permanent Disability, no further contributions on behalf of the
retired or disabled Participant shall be made. A retired or disabled Participant
may elect to withdraw the balance in his or her Contribution Account by
notifying the Sponsoring Employer in writing at least 15 days prior to the last
day of the Plan Quarter. In the event no election to withdraw has been made, the
balance accumulated in the retired or disabled Participant's Contribution
Account shall be used to purchase shares of Common Stock in accordance with
Article IV hereof. In the event a retired or disabled Participant shall die
during the Plan Quarter of such Participant's retirement or disability and such
Participant shall not have notified his or her Sponsoring Employer of his or her
desire to withdraw his or her Contribution Account, the executor or
administrator of such Participant's estate shall have all the rights provided
pursuant to Section 3.05(a) hereof.


                                   ARTICLE IV.

                            PURCHASE OF COMMON STOCK

            4.01  PURCHASE OF COMMON STOCK.

            (a) On each Purchase Date, each Participant's Contribution Account
shall be used to purchase the maximum number of whole and fractional shares of
Common Stock determined by dividing (i) the Participant's Contribution Account
as of such Purchase Date by (ii) the Purchase Price in respect of such Plan
Quarter.

            (b) If, in any Plan Quarter, the total number of shares of Common
Stock to be purchased pursuant to the Plan by all Participants exceeds the
number of shares authorized under the Plan, then each Participant shall purchase
his or her pro rata portion of the shares of Common Stock remaining available
under the Plan based on the balances in each Participant's Contribution Account
as of the Purchase Date in respect of such Plan Quarter.


                                       C-5
<PAGE>   49
            (c) Any cash dividends paid with respect to shares of Common Stock
held for the account of a Participant shall be, as determined by the Committee
on a uniform basis as to all Participants, either (i) distributed to the
Participant or (ii) credited to the Participant's Contribution Account and used,
in the same manner as payroll deductions, to purchase additional shares of
Common Stock under the Plan on the next Purchase Date (subject to the
limitations of Section 3.02 hereof).

            4.02 PURCHASE PRICE. For each Plan Quarter, the Purchase Price per
share of Common Stock purchased pursuant to the Plan shall be the lesser of (a)
85% of the Closing Market Price on the Commencement Date of such Plan Quarter,
and (b) 85% of the Closing Market Price on the Purchase Date of such Plan
Quarter.

            4.03  NOTICE OF PURCHASE, STOCK CERTIFICATES, VOTING RIGHTS.

            (a) After the Purchase Date in respect of each Plan Quarter, a
report will be made by the Company or its agent to each Participant stating the
entries made to his or her Contribution Account, the number of shares of Common
Stock purchased and the applicable Purchase Price.

            (b) Evidence of shares of Common Stock purchased under the Plan
shall be maintained under the Plan for the account of each Participant and
registered in the manner determined by the Committee. Certificates for the
number of whole shares credited to a Participant's account under the Plan will
be issued to a Participant at any time promptly upon written request to the
Company or its agent; provided, however, that the Company may, at its election,
issue such certificates at such time or times as the Committee deems
appropriate, including, without limitation, following an Employee's termination
of employment with a Sponsoring Employer.

            (c) Shares of Common Stock held under the Plan for the account of
each Participant shall be voted by the holder of record of such shares in
accordance with the Participant's instructions.

            4.04 NOTIFICATION OF DISPOSITION OF STOCK. If a Participant or
former Participant disposes of a share of Common Stock purchased under the Plan
prior to two (2) years after the Commencement Date of the Plan Quarter during
which such share was purchased, then such Participant or former Participant
shall notify his or her Sponsoring Employer immediately of such disposition in
writing.


                                   ARTICLE V.

                            MISCELLANEOUS PROVISIONS

            5.01  SHARES SUBJECT TO PLAN; ADJUSTMENTS.

            (a) The maximum number of shares of Common Stock which may be
purchased under the Plan is 1,500,000 subject, however, to adjustment as
hereinafter set forth. The shares of Common Stock to be purchased under the Plan
will be made available, at the discretion of the Board of Directors or the
Committee, either from authorized but unissued shares of Common Stock or from
previously issued shares of Common Stock reacquired by the Company, including
shares purchased on the open market.

            (b) If the outstanding shares of Common Stock of the Company are
increased, decreased, or exchanged for a different number or kind of shares or
other securities, or if additional shares or new or different shares or other
securities are distributed with respect to such shares of Common Stock or other
securities, through merger, consolidation, spin off, sale of all or
substantially all the property of the Company, reorganization, recapitalization,
reclassification, stock dividend, stock split, reverse stock split or other
distribution with respect to such shares of Common Stock, or other securities,
an appropriate and proportionate adjustment may be made in the maximum number
and kind of shares provided in Section 5.01(a) hereof, subject in the case of
certain corporate reorganizations to the requirements of Section 424(a) 


                                       C-6
<PAGE>   50
of the Code.

            5.02  ADMINISTRATION OF THE PLAN.

            (a) Pursuant to the direction of the Board of Directors, the
Committee shall be responsible for the administration of the Plan. The Committee
shall have the discretionary authority to interpret the Plan and determine all
questions arising in the administration, application and operation of the Plan,
including all questions of fact and all questions of interpretation of the
provisions of the Plan. All such determinations by the Committee shall be
conclusive and binding on all persons. The Committee, from time to time, may
adopt, amend and rescind rules and regulations not inconsistent with the Plan
for carrying out the Plan, and may approve the forms of any documents or
writings provided for in the Plan. The Committee shall have full discretionary
authority to delegate ministerial functions of the Plan to employees of the
Company. No member of the Board of Directors or the Committee shall be liable
for any action, determination or omission taken or made in good faith with
respect to the Plan or any right granted hereunder.

            (b) The Committee may in its discretion engage a bank trust
department, securities brokerage firm or other financial institution as agent to
perform custodial and record-keeping functions for the Plan, such as holding
record title to the Participants' stock certificates, maintaining an individual
investment account for each Participant and providing periodic account status
reports to Participants.

            (c) The Committee shall have the authority to adopt and enforce such
special rules and restrictions under the Plan to be applicable to Participants
who are subject to Section 16 of the Securities Exchange Act of 1934, as
amended, as the Committee shall deem are necessary or appropriate to exempt
certain Plan transactions from the requirements of such Section 16.

            (d) The Company shall bear the cost of administering the Plan,
including any fees, costs and expenses relating to the purchase of shares of
Common Stock under the Plan. Notwithstanding the foregoing, Participants will be
responsible for all fees, costs and expenses incurred in connection with the
disposition of shares of Common Stock purchased under the Plan.

            5.03  TERMINATION AND AMENDMENT OF THE PLAN.

            (a) The Company may, by action of the Board of Directors, terminate
the Plan at any time and for any reason. The Plan shall automatically terminate
upon the purchase by Participants of all shares of Common Stock subject to the
Plan under Section 5.01 hereof, unless such number of shares shall be increased
by the Board of Directors and such increase shall be approved by the
shareholders of the Company. Upon termination of the Plan, as soon as
practicable, there shall be refunded to each Participant the entire cash balance
in his or her Contribution Account, and there shall be forwarded to each
Participant certificates for all whole shares of Common Stock held under the
Plan for the account of such Participant.

            (b) The Board of Directors reserves the right to modify, alter or
amend the Plan at any time and from time to time to any extent that it may deem
advisable, including, without limiting the generality of the foregoing, any
amendment deemed necessary to ensure compliance of the Plan with Section 423 of
the Code. Notwithstanding the foregoing, no amendment of the Plan shall operate
to reduce any amounts previously allocated to a Participant's Contribution
Account nor to reduce a Participant's rights with respect to shares of Common
Stock previously purchased and held on his or her behalf under the Plan. The
Board of Directors may suspend operation of the Plan for any period as it may
deem advisable.

            5.04 GOVERNING LAW; COMPLIANCE WITH LAW. The Plan shall be construed
in accordance with the laws of the Commonwealth of Virginia. The Company's
obligation to sell and deliver shares of Common Stock hereunder shall be subject
to all applicable federal and state laws, rules and regulations and to such
approvals by any regulatory or governmental agency as may, in the opinion of
counsel for the Company, be required. The Company may make such provisions as it
may deem appropriate for the 


                                       C-7
<PAGE>   51
withholding of any taxes or payment of any taxes which it determines it may be
required to withhold or pay in connection with a Participant's participation in
the Plan.

            5.05 NO ASSIGNMENT. The purchase rights granted hereunder are not
assignable or transferable by the Participants, other than by will or the laws
of descent and distribution, and are exercisable during the Participant's
lifetime only by the Participant. Any attempted assignment, transfer or
alienation not in compliance with the terms of the Plan shall be null and void
for all purposes and respects.

            5.06 NO CONTRACT OF EMPLOYMENT. The Plan will not be deemed to
constitute a contract between a Sponsoring Employer and any Participant or to be
a consideration or an inducement for the employment of any Participant or
Employee. Nothing contained in the Plan shall be deemed to give any Participant
or Employee the right to be retained in the service of a Sponsoring Employer or
to interfere with the right of a Sponsoring Employer to discharge any
Participant or Employee at any time regardless of the effect which such
discharge shall have upon him or her as a Participant of the Plan.

            5.07 NO RIGHTS AS STOCKHOLDER. No eligible Employee or Participant
shall by reason of participation in the Plan have any rights of a stockholder of
the Company until he or she acquires shares of Common Stock as herein provided.
