                    EMPLOYMENT AND NON-INTERFERENCE AGREEMENT

                  This Employment and Non-Interference Agreement (this
"Agreement"), is dated as of March 1, 1999, by and between Mark A. Kissman (the
"Executive") and SPACEHAB, Incorporated, a Washington corporation (the
"Company").

                  WHEREAS, the Company wishes to retain the future services of
Executive for the Company;

                  WHEREAS, Executive is willing, upon the terms and conditions
set forth in this Agreement, to provide services hereunder; and

                  WHEREAS, the Company wishes to secure Executive's
non-interference, upon the terms and conditions set forth in this Agreement.

                  NOW, THEREFORE, in consideration of the mutual promises and
covenants contained herein, and intending to be legally bound hereby, the
parties hereto agree as follows:

                  1.       Nature of Employment

                  Subject to Section 3, the Company hereby employs Executive,
and Executive agrees to accept such employment, during the Term of Employment
(as defined in Section 3(a)), as Vice President, Finance and Chief Financial
Officer and to undertake such duties and responsibilities as may be reasonably
assigned to Executive from time to time by the Chief Executive Officer, Board of
Directors of the Company, or such other appropriately authorized or designated
executive officer of the Company.

                  2.       Extent of Employment

                  (a) During the Term of Employment, Executive shall perform his
obligations hereunder faithfully and to the best of his ability under the
direction of the Chief Executive Officer, Chief Operating Officer, Board of
Directors of the Company, or such other appropriately authorized or designated
executive officer of the Company, and shall abide by the rules, customs and
usages from time to time established by the Company.

                  (b) During the Term of Employment, Executive shall devote all
of his business time, energy and skill as may be reasonably necessary for the
performance of his duties, responsibilities and obligations under this Agreement
(except for vacation periods and reasonable periods of illness or other
incapacity), consistent with past practices and norms with respect to similar
positions.

                  (c) Nothing contained herein shall require Executive to follow
any directive or to perform any act which would violate any laws, ordinances,
regulations or rules of any governmental, regulatory or administrative body,
agent or authority, any court or judicial authority, or any public, private or
industry regulatory authority. Executive shall act in accordance with the laws,
ordinances, regulations or rules of any governmental, regulatory or
<PAGE>   2
administrative body, agent or authority, any court or judicial authority, or any
public, private or industry regulatory authority.

                  3.       Term of Employment; Termination

                  (a) The "Term of Employment" shall commence on March 1, 1999
and shall continue through July 31, 1999 (the "Initial Term"), subject to
automatic annual renewal for one-year terms thereafter (the "Additional Term"),
unless either the Company or Executive notifies the other party of its intent
not to renew at least ninety (90) days prior to the end of the Initial Term or
Additional Term as the case may be. Should Executive's employment by the Company
be earlier terminated pursuant to Section 3(b), the Term of Employment shall end
on the date of such earlier termination.

                  (b) Subject to the payments contemplated by Section 3(d), the
Term of Employment may be terminated at any time by the Company:

                           (i) upon the death of Executive;

                           (ii) in the event that because of physical or mental
                  disability, Executive is unable to perform and does not
                  perform his duties hereunder, for a continuous period of 90
                  days, and an experienced, recognized physician specializing in
                  such disabilities certifies as to the foregoing in writing;

                           (iii) for Cause or Material Breach (each as defined
                  in Section 3(d));

                           (iv) upon the continuous poor or unacceptable
                  performance of Executive's duties to the Company, in the sole
                  judgment of the Board of Directors of the Company, which has
                  remained uncured for a period of 90 days after the delivery of
                  notice by the Company to the Executive of such dissatisfaction
                  with Executive's performance; or

                           (v) for any other reason not referred to in clauses
                  (i) through (iv), or for no reason, such that this Agreement
                  shall be construed as terminable at will by the Company.

Executive acknowledges that no representations or promises have been made
concerning the grounds for termination or the future operation of the Company's
business, and that nothing contained herein or otherwise stated by or on behalf
of the Company modifies or amends the right of the Company to terminate
Executive at any time, with or without Material Breach or Cause. Termination
shall become effective upon the delivery by the Company to Executive of notice
specifying such termination and the reasons therefor, subject to the
requirements for advance notice and an opportunity to cure provided in this
Agreement, if and to the extent applicable.

                  (c) Subject to the payments contemplated by Section 3(d), the
Term of Employment may be terminated at any time by Executive:

<PAGE>   3
                           (i) upon the death of Executive;

                           (ii) in the event that because of physical or mental
                  disability, Executive is unable to perform and does not
                  perform his duties hereunder, for a continuous period of 90
                  days, and an experienced, recognized physician specializing in
                  such disabilities certifies as to the foregoing in writing;

                           (iii) as a result of the Company's material reduction
                  in Executive's authority, perquisites, position, title or
                  responsibilities (other than such a reduction by the Company
                  because of a temporary illness or disability or such a
                  reduction which affects all of the Company's senior executives
                  on a substantially equal or proportionate basis as a result of
                  financial results, conditions, prospects, reorganization,
                  workout or distressed condition of the Company), or the
                  Company's willful, material violation of its obligations under
                  this Agreement, in each case, after 30 days' prior written
                  notice by Executive to the Company and its Board of Directors
                  and the Company's failure thereafter to cure such reduction or
                  violation within such 30 days; or

                           (iv) voluntarily or for any reason not referred to in
                  clauses (i) through (iii), or for no reason, in each case,
                  after 90 days' prior written notice to the Company and its
                  Board of Directors.

                  (d) For the purposes of this Section 3:

                  "Cause" shall mean any of the following: (i) Executive's
conviction of any crime or criminal offense involving the unlawful theft or
conversion of substantial monies or other property or any other felony (other
than a criminal offense arising solely under a statutory provision imposing
criminal liability on the Executive on a per se basis due to the offices held by
the Executive); or (ii) Executive's conviction of fraud or embezzlement.

                  "Material Breach" shall mean any of the following: (i)
Executive's breach of any of his fiduciary duties to the Company or its
stockholders or making of a willful misrepresentation or omission which breach,
misrepresentation or omission would reasonably be expected to materially
adversely affect the business, properties, assets, condition (financial or
other) or prospects of the Company; (ii) Executive's willful, continual and
material neglect or failure to discharge his duties, responsibilities or
obligations prescribed by Sections 1 and 2 (other than arising solely due to
physical or mental disability); (iii) Executive's habitual drunkenness or
substance abuse which materially interferes with Executive's ability to
discharge his duties, responsibilities or obligations prescribed by Sections 1
and 2; (iv) Executive's willful, continual and material breach of any
noncompetition or confidentiality agreement with the Company, including without
limitation, those set forth in Sections 7 and 8 of this Agreement; and (v)
Executive's gross neglect of his duties and responsibilities, as determined by
the Company's Board of Directors; in each case, for purposes of clauses (i)

                                       3
<PAGE>   4
through (v), after the Company or the Board of Directors has provided Executive
with 30 days' written notice of such circumstances and the possibility of a
Material Breach, and Executive fails to cure such circumstances and Material
Breach within those 30 days.

                           (i) In the event Executive's employment is terminated
                  pursuant to Section 3(b)(i) [death], 3(b)(ii) [disability] or
                  3(b)(v) [any other reason or no reason] or 3(c)(i) [death],
                  3(c)(ii) [disability] or 3(c)(iii) [material reduction], the
                  Company will: (A) pay to Executive (or his estate or
                  representative) the full amounts to which the Executive would
                  be entitled to under Section 4(a) for the period from
                  effectiveness of termination through the sixth month
                  anniversary of termination; and (B) pay to Executive (or his
                  estate or representative) the benefits described in Section 6
                  through the sixth month anniversary of termination.

                           Payment of the amounts and provision of the benefits
                  described above will be made in accordance with the timetable
                  and schedule for such payments contemplated therefor as if
                  such termination did not occur, and will be subject to the
                  other provisions of this Agreement, including Section 3(g),
                  and Sections 7 and 8. If the Company makes the payments
                  required by this Section 3(d)(i), such payments will
                  constitute severance and liquidated damages, and the Company
                  will not be obligated to pay any further amounts to Executive
                  under this Agreement or otherwise be liable to Executive in
                  connection with any termination.

                           (ii) In the event Executive's employment is
                  terminated pursuant to Section 3(b)(iii) [Cause or Material
                  Breach], 3(b)(iv) [poor performance], or 3(c)(iv) [voluntary],
                  the Company will not be obligated to pay any further amounts
                  to Executive under this Agreement.

                  (e) In the event the Term of Employment is terminated and the
Company is obligated to make payments to Executive pursuant to Section 3(d)(i),
Executive shall have a duty to seek to obtain alternative employment; and if
Executive thereafter obtains alternative employment, the Company's payment
obligations under Section 3(d)(i), including its obligation to provide insurance
coverage, if any, will be mitigated and reduced by and to the extent of
Executive's compensation under such alternative employment during the period for
which payments are owed by the Company pursuant to Section 3(d)(i). Moreover, in
the event that Executive is employed by or engaged in a Competitive Business as
contemplated by Section 8(a)(i), then the Company will thereupon no longer be
obligated to make payments under Section 3(d)(i).

                  (f) In the event the Term of Employment is terminated and the
Company is obligated to make payments pursuant to Section 3(d)(i), Executive
hereby waives any and all claims against the Company and its respective
officers, directors, employees, agents, or representatives, stockholders and
affiliates relating to his employment during the term hereof and this Agreement.

                                       4

                  (g) Termination of the Term of Employment will not terminate
Sections 3(d), 3(f), and 7 through 21.

                  4.       Compensation

                  During the Term of Employment, the Company shall pay to
Executive:

                  (a) As base compensation for his services hereunder, in
semi-monthly installments, a base salary at a rate of not less than $170,000 per
annum. Such amounts may be increased (but not decreased) annually at the
discretion of the Compensation Committee of the Board of Directors based upon an
annual review by the Compensation Committee of the Board of Directors of
Executive's performance.

                  (b) An annual incentive bonus, if any, based on Executive's
and/or Company's performance as determined and approved by the Compensation
Committee of the Board of Directors.

                  (c) An annual stock option grant, if any, based on
Executive's, Company's and/or Company Stock performance as determined and
approved by the Compensation Committee of the Board of Directors.

                  5.       Reimbursement of Expenses

                  During the Term of Employment, the Company shall pay all
expenses, including without limitation, transportation, lodging and food for
Executive to attend conventions, conferences and meetings that the Company
determines are necessary or in the best interest of the Company, and for any
ordinary and reasonable expenses incurred by Executive in the conduct of the
Business of the Company. Travel outside the United States shall be subject to
the prior approval of an executive officer of the Company.

                  6.       Benefits

                  During the Term of Employment, Executive shall be entitled to
benefits (including health, disability, pension and life insurance benefits
consistent with Company policy, or as increased from time to time), in each
case, in accordance with guidelines or established from time to time, by the
Board of Directors for senior executives of the Company.

                  7.       Confidential Information

                  (a) Executive acknowledges that his employment hereunder gives
him access to Confidential Information relating to the Company's Business and
its customers which must remain confidential. Executive acknowledges that this
information is valuable, special, and a unique asset of the Company's Business,
and that it has been and will be developed by the Company at considerable effort
and expense, and if it were to be known and used by others engaged in a
Competitive Business, it would be harmful and detrimental to the interests of
the

                                       5
<PAGE>   6

Company. In consideration of the foregoing, Executive hereby agrees and
covenants that, during and after the Term of Employment, Executive will not,
directly or indirectly in one or a series of transactions, disclose to any
person, or use or otherwise exploit for Executive's own benefit or for the
benefit of anyone other than the Companies, Confidential Information (as defined
in Section 10), whether prepared by Executive or not; provided, however, that
any Confidential Information may be disclosed to officers, representatives,
employees and agents of the Companies who need to know such Confidential
Information in order to perform the services or conduct the operations required
or expected of them in the Business (as defined in Section 10). Executive shall
use his best efforts to prevent the removal of any Confidential Information from
the premises of the Companies, except as required in his normal course of
employment by the Company. Executive shall use his best efforts to cause all
persons or entities to whom any Confidential Information shall be disclosed by
him hereunder to observe the terms and conditions set forth herein as though
each such person or entity was bound hereby. Executive shall have no obligation
hereunder to keep confidential any Confidential Information if and to the extent
disclosure of any thereof is specifically required by law; provided, however,
that in the event disclosure is required by applicable law, Executive shall
provide the Company with prompt notice of such requirement, prior to making any
disclosure, so that the Company may seek an appropriate protective order. At the
request of the Company, Executive agrees to deliver to the Company, at any time
during the Term of Employment, or thereafter, all Confidential Information which
he may possess or control. Executive agrees that all Confidential Information of
the Companies (whether now or hereafter existing) conceived, discovered or made
by him during the Term of Employment exclusively belongs to the Companies (and
not to Executive). Executive will promptly disclose such Confidential
Information to the Company and perform all actions reasonably requested by the
Company to establish and confirm such exclusive ownership.

                  (b) In the event that Executive breaches his obligations in
any material respect under this Section 7, the Company, in addition to pursuing
all available remedies under this Agreement, at law or otherwise, and without
limiting its right to pursue the same shall cease all payments to Executive
under this Agreement.

                  (c) The terms of this Section 7 shall survive the termination
of this Agreement regardless of who terminates this Agreement, or the reasons
therefor.

                  8.       Non-Interference

                  (a) Executive acknowledges that the services to be provided
give him the opportunity to have special knowledge of the Company and its
Confidential Information and the capabilities of individuals employed by or
affiliated with the Company, and that interference in these relationships would
cause irreparable injury to the Company. In consideration of this Agreement,
Executive covenants and agrees that:

                           (i) During the Restricted Period (which shall not
                  include any period of violation of this Agreement by the
                  Executive), Executive will not, without the express written
                  approval of the Board of Directors of the Company, anywhere in
                  the Market, directly or indirectly, in one or a series of
                  transactions, own,

                                       6
<PAGE>   7
                  manage, operate, control, invest or acquire an interest in, or
                  otherwise engage or participate in, whether as a proprietor,
                  partner, stockholder, lender, director, officer, employee,
                  joint venturer, investor, lessor, supplier, customer, agent,
                  representative or other participant, in any Competitive
                  Business without regard to (A) whether the Competitive
                  Business has its office, manufacturing or other business
                  facilities within or without the Market, (B) whether any of
                  the activities of Executive referred to above occur or are
                  performed within or without the Market or (C) whether
                  Executive resides, or reports to an office, within or without
                  the Market; provided, however, that (x) Executive may,
                  anywhere in the Market, directly or indirectly, in one or a
                  series of transactions, own, invest or acquire an interest in
                  up to five percent (5%) of the capital stock of a corporation
                  whose capital stock is traded publicly, or that (y) Executive
                  may accept employment with a successor company to the Company.

                           (ii) During the Restricted Period (which shall not
                  include any period of violation of this Agreement by
                  Executive), Executive will not without the express prior
                  written approval of the Board of Directors of the Company (A)
                  directly or indirectly, in one or a series of transactions,
                  recruit, solicit or otherwise induce or influence any
                  proprietor, partner, stockholder, lender, director, officer,
                  employee, sales agent, joint venturer, investor, lessor,
                  supplier, customer, agent, representative or any other person
                  which has a business relationship with the Company or had a
                  business relationship with the Company within the twenty-four
                  (24) month period preceding the date of the incident in
                  question, to discontinue, reduce or modify such employment,
                  agency or business relationship with the Company, or (B)
                  employ or seek to employ or cause any Competitive Business to
                  employ or seek to employ any person or agent who is then (or
                  was at any time within six months prior to the date Executive
                  or the Competitive Business employs or seeks to employ such
                  person) employed or retained by the Company. Notwithstanding
                  the foregoing, nothing herein shall prevent Executive from
                  providing a letter of recommendation to an employee with
                  respect to a future employment opportunity.

                           (iii) The scope and term of this Section 8 would not
                  preclude him from earning a living with an entity that is not
                  a Competitive Business.

                  (b) The terms of this Section 8 shall survive termination of
this Agreement regardless of who terminates this Agreement, or the reasons
therefor.

                  9.       Inventions

                  (a) Each invention, improvement or discovery made or conceived

thereafter without charge to the Company, but at the request and expense of the
Company, assist the Company in obtaining or vesting in itself patents upon such
improvements and inventions. All such inventions, improvements or discoveries

                  (b) In the event that Executive breaches his obligations in
any material respect under Sections 7, 8 or this Section 9, the Company, in

                  12.      Previous Agreements; Executive's Representation

                  (a) Attached hereto as Annex A are all previous employment or
severance agreements, if any, by and between Executive and the Company
(collectively, the "Prior Employment Agreements"). Executive and the Company
hereby cancel, void and render without force and effect all Prior Employment
Agreements, and the Executive releases and discharges the Company from any
further obligations or liabilities thereunder. Notwithstanding the foregoing,
the terms and provisions in any Prior Employment Agreement relating to any
grants of stock options or other derivative securities for the purchase of the
Company's common stock, no par value per share, shall remain in full force and
effect and shall not be amended in any manner as a result of the execution of
this Agreement.

                  (b) Executive hereby warrants and represents to the Company
that Executive has carefully reviewed this Agreement and has consulted with such
advisors as Executive considers appropriate in connection with this Agreement,
is not subject to any covenants, agreements or restrictions, including without
limitation any covenants, agreements or restrictions arising out of Executive's
prior employment, which would be breached or violated by Executive's execution
of this Agreement or by Executive's performance of his duties hereunder.

                  13.      Other Matters

                  Executive agrees and acknowledges that the obligations owed to
Executive under this Agreement are solely the obligations of the Company, and
that none of the Companies' stockholders, directors, officers, affiliates,
representatives, agents or lenders will have any obligations or liabilities in
respect of this Agreement and the subject matter hereof.

                  14.      Validity

                  If, for any reason, any provision hereof shall be determined
to be invalid or unenforceable, the validity and effect of the other provisions
hereof shall not be affected thereby.

                  15.      Severability

                  Whenever possible, each provision of this Agreement will be
interpreted in such manner as to be effective and valid under applicable law,
but if any provision of this Agreement is held to be invalid, illegal or
unenforceable in any respect under any applicable law or rule in any
jurisdiction, such invalidity, illegality or unenforceability will not affect
any other provision or any other jurisdiction, but this Agreement will be
reformed, construed and enforced in such jurisdiction as if such invalid,
illegal or unenforceable provision had never been contained herein. If any court
determines that any provision of Section 8 or any other provision hereof is
unenforceable because of the power to reduce the scope or duration of such
provision, as the case may be and, in its reduced form, such provision shall
then be enforceable.

                  16.      Waiver of Breach; Specific Performance

                  The waiver by the Company or Executive of a breach of any
provision of this Agreement by the other party shall not operate or be construed
as a waiver of any other breach of such other party. Each of the parties (and
third party beneficiaries) to this Agreement will be entitled to enforce its
rights under this breach of any provision of this Agreement and to exercise all
other rights existing in its favor. The parties hereto agree and acknowledge
that money damages may not be an adequate remedy for any breach of the
provisions of Sections 7, 8 and 9 of this Agreement and that any party (and
third party beneficiaries) may in its sole discretion apply to any court of law
or equity of competent jurisdiction for specific performance and/or injunctive
relief, including temporary restraining orders, preliminary injunctions and
permanent injunctions in order to enforce or prevent any violations of the
provisions of this Agreement. In the event either party takes legal action to
enforce any of the terms or provisions of this Agreement against the other
party, the party against whom judgement is rendered in such action shall pay the
prevailing party's costs and expenses, including but not limited to, attorneys'
fees, incurred in such action.

                  17.      Assignment; Third Parties

                  Neither Executive nor the Company may assign, transfer,
pledge, hypothecate, encumber or otherwise dispose of this Agreement or any of
his or its respective rights or obligations hereunder, without the prior written
consent of the other. The parties agree and acknowledge that each of the
Companies and the stockholders and investors therein are intended to be third
party beneficiaries of, and have rights and interests in respect of, Executive's
agreements set forth in Sections 7, 8 and 9.

                  18.      Amendment; Entire Agreement

                  This Agreement may not be changed orally but only by an
agreement in writing agreed to by the party against whom enforcement of any
waiver, change, modification, extension or discharge is sought. This Agreement
embodies the entire agreement and understanding of the parties hereto in respect
of the subject matter of this Agreement, and supersedes and replaces all prior
Agreements, understandings and commitments with respect to such subject matter.

                  19.      Litigation

ARBITRATION. IN CONNECTION WITH THE FOREGOING, THE PARTIES HEREBY WAIVE ANY
